It is also a way to make money to operate the baby clip machine. The quality of the machine directly affects whether the business is booming. Although there are after-sales services, it will affect the normal operation. If there is no one to manage the machine, there will be less people to play. Only by ensuring the good state of the machine can we have stable income. Therefore, daily maintenance is essential.

When the coin cannot be put in, it may be that the coin hole is damaged or the game coin is too strict. The potentiometer on the top should be properly adjusted. Clockwise rotation is to make it loose, and anti clockwise rotation is to make it tighter. When twisting, pay attention to the strength, and do not cause additional damage. When there is no response from the doll clamping machine after the coin is put in, consider the reason why the game coin is too loose. The same as the above method, or check whether the switch of the coin dispenser is turned on, sometimes the switch is turned off due to various reasons, and check whether the trigger time switch is turned on. When the claw reaches the bottom and cannot be lifted up, it is necessary to check whether the microswitch on the crown block is sensitive. When the claw grabs in mid air, it is considered that the microswitch is damaged or the spring elasticity under the hardware is not enough. When the paw does not move after the coin is put in, consider whether the connection on the rocker of the machine is normal or the safety tube on the power supply fails. When the power is turned off, move the crown block to the middle of the machine, and then turn on the power supply to observe whether the crown block can return to the top of the exit.

When the crane starts to move automatically after the coin is put in, it should be considered that the rocker or the main board is damaged. During the use of the doll clamping machine, some people will cause damage to the inner part of the rocker. Open the inner part and pull out a line in the automatic moving direction. If the test returns to normal, it is necessary to replace a rocker for micro motion. When it is confirmed that the rocker has no problem, it is necessary to check the main board First, remove the rocker connection, then try to see if the fault exists, and then check whether the motor of the crown block can work normally. The front, rear, left and right four should be detected. If it can not be solved, a motherboard should be replaced.

When the crown block is not in the position above the exit after power on, and the display screen shows 01 and keeps flashing, it is considered that there is a problem with the binding belt. First, open the door of the doll grabbing machine, turn off the machine, and detect whether the binding belt above the crown block is completely removed. When the doll clamping machine cannot be powered on normally, check the switch to see if the wiring is normal, whether there is an open circuit, and whether the contact is good. Then check the indicator light of the power box. If the normal power supply light is on, replace another power box to check whether there is a problem. Since the voltage provided by the power box exists in a range, you can adjust it with a potentiometer, and then check the main board, if the light is on Then change another motherboard to check whether the motherboard is normal.
