The following will refer to the accompanying drawings. Figures 1-8 The present invention will be described in detail with reference to the embodiments.

[0027] A pusher for circuit board processing includes a worktable 1 with two parallel conveyor belts 2 rotatably mounted on it. Weighing sensors 3 and object sensors 4 are respectively mounted on the two conveyor belts 2 to detect circuit boards. Two sets of drive rollers 17 are rotatably mounted at both ends of the worktable 1, and the drive rollers 17 are mounted on the output end of a servo motor 18. The two conveyor belts 2 are adapted and connected to the two sets of drive rollers 17. Baffles 19 are fixedly mounted on both sides of the two conveyor belts 2 to prevent circuit boards from falling off the conveyor belts 2. Two baffles 19 near the processing unit also have through slots 10 to facilitate the passage of circuit boards.

[0028] Two conveyor belts 2 are used for feeding circuit boards. When the object sensor 4 senses the circuit board, the feeding conveyor belt is paused. After the pusher plate 8 pushes the circuit board under the processing component 11, it is processed. After processing is completed, the circuit board is pushed into the other unloading conveyor belt 2. After the weighing sensor 3 senses the circuit board on the conveyor belt 2, the conveyor belt 2 is started to transport the circuit board to the external storage frame, completing the unloading operation.

[0029] The object sensor 4 is a laser sensor, a technology currently available. After detecting an object, it works with the PLC control system to transmit the sensed information to the control system. The control system then uses a preset procedure to control the start and stop of the servo motor 18, achieving automated material feeding. The weighing sensor 3 is a technology currently available that can weigh circuit boards. After sensing the weight of the circuit board, it transmits the information to the control system. The control system then uses a preset procedure to control the start and stop of the servo motor 18, achieving automated material unloading.

[0030] The load cell 3 is fixedly installed on the top wall of the workbench opposite to the through groove 10, below the conveyor belt 2 at the end away from the object sensor 4. It can detect the weight of the circuit board and corresponds to the conveyor belt 2 used for unloading. The object sensor 4 is installed on the inner wall of the baffle 19 on the same side as the first electric telescopic rod 5, opposite to the through groove 10. It can detect the object of the circuit board and corresponds to the conveyor belt 2 used for loading.

[0031] A first electric telescopic rod 5 is fixedly installed on the same side as the object sensor 4. A storage rack 6 is fixedly installed at the telescopic end of the first electric telescopic rod 5. A second electric telescopic rod 7 is fixedly installed on the inner wall of the storage rack 6. A push plate 8 is fixedly installed at the telescopic end of the second electric telescopic rod 7. After the object sensor 4 senses the circuit board, the conveyor belt 2 stops conveying. At this time, the first electric telescopic rod 5 is activated, which drives the storage rack 6 to move closer to the circuit board. That is, it drives the push plate 8 to move closer to the circuit board, so that it pushes the circuit board 8 through the through groove 10 and moves it below the processing component 11.

[0032] The first electric telescopic rod 5 is fixedly installed on the inner wall of the baffle 19. The inner wall of the storage rack 6 is fixedly provided with a receiving groove 20. The second electric telescopic rod 7 is fixedly installed on the inner wall of the receiving groove 20. A rubber pad 21 is fixedly installed on the side of the push plate 8 near the processing unit. The dimensions of the storage rack 6 and the push plate 8 are both smaller than the dimensions of the through groove 10, allowing passage within the through groove 10. When the second electric telescopic rod 7 is retracted to its shortest length, the push plate 8 is just inside the receiving groove 20. When the first electric telescopic rod 5 is extended to its longest length, it can push the circuit board under the processing assembly 11. When both the first electric telescopic rod 5 and the second electric telescopic rod 7 are extended to their longest length, the push plate 8 can push the circuit board onto the opposite conveyor belt 2 used for unloading.

[0033] A processing unit is set between the two conveyor belts 2. The processing unit includes several support plates 9. A through groove 10 and a processing component 11 are fixedly set on one of the support plates 9. The through groove 10 and the processing component 11 are both set on a support plate 9 parallel to the baffle 19. The processing component 11 is set at the top of the support plate 9 and is a processing device for circuit boards, including a chip mounter or a drilling machine. The processing component 11 is the structure used for subsequent processing after the circuit board is fixed, such as a chip mounter or a drilling machine. It is adapted and combined with the pusher according to production needs.

[0034] There are three support plates 9. The other two symmetrical support plates 9 are each fixedly equipped with a third electric telescopic rod 12. The telescopic end of the third electric telescopic rod 12 is fixedly equipped with a clamping plate 13. The clamping plate 13 has a U-shaped structure, and a rubber pad 21 is also fixedly installed on its opposite inner side wall. Two limiting grooves 22 parallel to the baffle 19 are fixedly installed on the top wall of the workbench 1. The two clamping plates 13 can move in the two limiting grooves 22 respectively.

[0035] After the circuit board is pushed under the processing assembly 11, it needs to be clamped and fixed using the clamping plate 13 to facilitate subsequent processing. The third electric telescopic rod 12 is activated, causing it to move the two clamping blocks 13 closer to the circuit board. When the rubber pads 21 on both sides of the clamping plate 13 contact and abut against the sides of the circuit board, pressure is generated. The pressure sensor 16 can detect this pressure. When the detected pressure matches the preset pressure value of the control system, the control system instructs the third electric telescopic rod 12 to stop extending. This effectively clamps and fixes the circuit board without damaging it. The clamping plate 13 can move within the limiting groove, serving as a guide and enhancing stability.

[0036] A fourth electric telescopic rod 14 is symmetrically arranged on both sides of the clamping plate 13. A pressure block 15 is fixedly arranged at the telescopic end of the fourth electric telescopic rod 14. Pressure sensors 16 are arranged on the side wall of the pressure block 15 and the side wall of the clamping plate 13. Rubber pads 21 are also fixedly arranged on the opposite side wall of the pressure block 15. The pressure sensors 16 are respectively fixed between the rubber pad 21 and the side wall of the pressure block 15, and between the rubber pad 21 and the inner side wall of the clamping plate 13.

[0037] Then, the fourth electric telescopic rod 14 is activated, causing it to move the pressure blocks 15 closer to the other two sides of the circuit board. When the rubber pads 21 contact and abut against the other two side walls of the circuit board, pressure is generated. The pressure sensor 16 can sense this pressure. When the pressure sensed by the sensor matches the preset pressure value of the control system, the control system instructs the fourth electric telescopic rod 14 to stop extending and moving. At this time, the circuit board can be fixed and clamped without damaging it. In other words, the four side walls of the circuit board are clamped and fixed at this time, and circuit boards of different specifications and sizes can be clamped and fixed, which is highly flexible. The clamped and fixed circuit board then completes other processing steps with the cooperation of the processing component 11.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
