[0044] The cross arm plate 41 is arranged on the tray 21, and the power device 4 is fixed on the cross arm plate 41. The power device 4 is fixed on the cross arm plate 41 by screws. The output shaft of the power device 4 passes through the through hole 42 on the cross arm plate 41 and is connected with the push plate 3. The cross arm plate 41 provides a fixed support for the power device 4, so that it is stably installed on the tray 21, and ensures that the power device 4 does not shake or displace during operation, thereby providing a basic guarantee for the stable operation of the entire feeding device.

[0048] The lower end of the push plate 3 is provided with a brush 31, which can effectively prevent the nut from being jammed when moving in the tray 21. During the rotation of the push plate 3 to push the nut, part of the nut may be jammed at the edge or other parts of the tray 21 due to various reasons (such as uneven surface of the tray 21, mutual extrusion between nuts, etc.). The presence of the brush 31 can exert a certain external force on the nut when the nut is about to be jammed or has been jammed, so that the nut returns to the normal movement track, ensuring that the nut can smoothly enter the chute 1 from the discharge port 22, maintaining the smoothness of the feeding process. When the push plate 3 rotates, the rolling of the nut in the tray 21 may produce a large noise and vibration. When the brush 31 contacts the nut, it can play a certain buffering role, reducing the collision between the nuts and between the nut and the tray 21, thereby reducing the noise and vibration generated during the operation of the entire feeding device, improving the working environment, and also helping to reduce the damage caused by vibration of the equipment.

The embedded groove 32 provided at the lower end of the push plate 3 provides a precise installation position for the brush 31, so that the brush 31 can be accurately installed on the push plate 3, ensuring the positional accuracy during operation. At the same time, the upper end of the brush 31 is embedded in the embedded groove 32, and then fixed by the pressing member 33 provided at the embedded groove 32. This installation method can firmly connect the brush 31 to the push plate 3, avoiding the loosening and falling of the brush 31 during the rotation of the push plate 3, ensuring that the brush 31 can stably play its role, such as preventing the nut from being jammed, cleaning the tray debris, etc., facilitating the replacement and maintenance of the brush.

[0050] The bottom plate 26 of the tray 21 is provided with connecting holes 25 on both sides of the discharge port 22, and the guide plate of the chute 1 is provided with fixed holes corresponding to the connecting holes 25. The screw passes through the connecting holes 25 and the fixed holes and is connected with the nut, facilitating the connection with the chute.

[0051] The bottom plate 26 of the tray 21 is provided with a protective plate 6, which has a hardness lower than that of the nut. PVC, polyethylene (PE) or polypropylene (PP) and other materials can be used, which have certain hardness and wear resistance. The protective plate 6 is provided with corresponding openings corresponding to the discharge port 22 to avoid scratching the nut.

[0052] The power device 4 is electrically connected with the controller 7, which is a foot switch for user to control the feeding by himself, or a PLC control system including a circuit board, and the power device 4 is electrically connected with the circuit board to control the forward and reverse rotation of the motor and the reverse rotation after the motor is blocked. When the user needs to feed the nuts into the chute 1, the foot switch is stepped on, the circuit is connected, the current is transmitted to the power device 4, the power device 4 is started and drives the pushing plate 3 to rotate, so as to drive the nuts in the feeding tray 21 to rotate and enter the chute 1 from the discharge port 22; when the foot switch is released, the circuit is disconnected, the power device 4 stops working, and the feeding process is paused. In this way, the user can flexibly control the feeding time and amount of nuts according to the actual production needs.

[0053] Advantages: flexible operation. The user can control the start and stop of feeding by himself, which is very suitable for some work scenes that need to add nuts according to the specific operation rhythm, such as manual assembly work, which can feed on demand at any time, improving the flexibility and convenience of work.

[0054] Simple and easy to use: the operation mode of the foot switch is intuitive and easy to understand, without complex training, new employees can quickly operate, reducing the skill threshold of the operator.

[0055] Low cost: compared with some complex automatic control systems, the cost of the foot switch is relatively low, which is an economical and practical choice for some production scenes with limited budget.

[0056] The case of the PLC control system as the controller 7

[0057] Working principle: the circuit board in the PLC control system is pre-set with corresponding programs and logic. When the system starts, the circuit board sends signals to the power device 4 according to the set instructions to control the forward rotation of the motor. At this time, the power device 4 drives the pushing plate 3 to rotate in a specific direction, pushing the nuts from the discharge port 22 into the chute 1. When the motor is blocked (for example, the motor load is too large to rotate normally due to nut jamming), the circuit board will immediately issue instructions to reverse the motor to try to remove the blocking state and avoid equipment damage. Through this forward and reverse control logic, the stable operation of the feeding device is ensured.

[0058] Advantages: high degree of automation. The PLC control system can automatically run according to the pre-set program without frequent manual intervention, greatly improving the production efficiency and continuity. It can realize various complex feeding modes such as timed feeding and quantitative feeding to meet the needs of different production processes.

[0059] Strong fault handling capability: when the motor appears to be blocked, the system can automatically detect and take countermeasures in time, effectively protecting the power device 4 and other components, reducing the risk of equipment damage, reducing maintenance costs and downtime,

[0060] Precise control: the speed, direction and running time of the motor can be accurately controlled, so as to realize accurate control of the nut feeding speed and quantity, and ensure the stability and consistency of product quality,

[0061] Good scalability: the PLC control system has good scalability and can be easily integrated with other devices or systems, such as linkage control with other automated devices on the production line, further improving the automation level and intelligent degree of the entire production line.

[0062] Working principle and use method:

[0063] Pedal switch operation: when the nut needs to be transported, the operator steps on the pedal switch, the power device 4 starts, and the nut starts to be transported from the tray 21 to the nut positioning part 11 through the chute 1; after completing the feeding requirement, release the pedal switch, the feeding stops, and the start and stop of feeding can be controlled at any time according to the actual assembly rhythm;

[0064] PLC control system operation: start the PLC control system, the system automatically controls the power device 4 to run according to the preset program, realizes automatic feeding of the nut, and automatically executes countermeasures such as reverse rotation when abnormal conditions such as blockage occur during operation, the operator can adjust the feeding speed, quantity and other parameters by modifying the PLC program according to the production needs;

[0065] When the power is turned on or the power source is started, the output shaft starts to rotate, and since the power device 4 is connected with the push plate 3, this rotating motion is transmitted to the push plate 3, so that the push plate 3 starts to rotate in the tray 21. A large number of nuts are placed in the tray 21, and as the push plate 3 rotates, the nuts roll and move in the tray 21 under the action of the push plate 3. The bottom plate 26 of the tray 21 is provided with a discharge port 22, and the discharge port 22 is accurately corresponding to the upper opening of the chute 1. During the movement of the nuts in the tray 21, part of the nuts will reach the position of the discharge port 22. Due to the action of gravity and the pushing force of the push plate 3, these nuts will fall smoothly from the discharge port 22 into the chute 1. After the nuts enter the chute 1, they move to the delivery end under the guidance of the chute 1, until they reach the nut positioning part 11, where the nuts are accurately positioned, facilitating subsequent assembly through the assembly port 12 and other operations.
