[0028] Please refer to Figures 1 to 5 The application exemplarily provides a circuit board feeding and discharging device, which comprises:

[0029] A rack 1 is provided with a conveying platform 2, and the conveying platform 2 is provided with a carrier 3 for placing a circuit board, and the carrier 3 can be conveyed on the conveying platform 2;

[0030] A mechanical arm 4 is arranged on the rack 1;

[0031] A mounting plate 5 is arranged on a movable end of the mechanical arm 4;

[0032] A grabbing module 6 is arranged on the mounting plate 5, and the grabbing module 6 comprises a driving assembly and a clamping plate 19, the driving assembly comprises a driving piece 17 and a driving plate 18, the driving plate 18 is oppositely arranged on the driving piece 17, the driving plate 18 at least partially extends from one side of the driving piece 17 and is connected with the clamping plate 19, both ends of the clamping plate 19 are provided with an extending section 20 extending downward in the vertical direction, and the extending section 20 is provided with a clamping part 21 on the opposite side of the clamping plate 19, and the driving piece 17 can drive the driving plate 18 to move close to or away from each other, and drive the clamping part 21 to move close to or away from each other to clamp or release the circuit board.

[0033] In the circuit board feeding and discharging device provided by the application, the driving piece 17 drives the driving plate 18 to move close to or away from each other, and drives the clamping plate 19 to move synchronously, and the clamping part 21 moves close to or away from each other to clamp or release the circuit board, the mechanical arm 4 can drive the grabbing module 6 to move to realize the grabbing, feeding or discharging of the circuit board, improve the production efficiency, and ensure the stability of the clamping force during the feeding and discharging of the circuit board, avoid the circuit board from falling off during the clamping and moving, and reduce the risk of damage to the circuit board.

[0034] In the embodiment, the clamping part 21 is provided with a groove structure 22, when clamping the circuit board, the groove structure 22 is in contact with the two sides of the circuit board, the upper and lower groove walls of the groove structure 22 limit the circuit board in the vertical direction, specifically, the clamping part 21 is arranged at both ends of the clamping plate 19, and the groove structure 22 matched with the clamping part 21 ensures that the clamping force on both sides of the circuit board is the same when the clamping plate 19 moves close to each other from the two sides of the circuit board and clamps the circuit board, improves the stability of clamping, and the upper and lower groove walls of the groove structure 22 can limit the top surface and the bottom surface of the circuit board, which can avoid the circuit board from sliding greatly during clamping, and further ensure the stability of clamping.

[0035] In the above embodiment, the driving member 17 is provided with an elastic telescopic member 23 on the side close to the circuit board. When the grabbing module 6 is close to the circuit board, the elastic telescopic member 23 is in contact with the surface of the circuit board, the clamping portions 21 are close to each other, the groove structure 22 is in contact with the two sides of the circuit board, the elastic telescopic member 23 cooperates with the upper groove wall of the groove structure 22 to limit the circuit board, and when the clamping portions 21 clamp the circuit board and move, the elastic telescopic member 23 cooperates with the lower groove wall of the groove structure 22 to limit the circuit board. Specifically, when clamping the circuit board, the elastic telescopic member 23 is compressed and retracted by the circuit board when in contact with the circuit board, cooperates with the upper groove wall of the groove structure 22, and limits the circuit board in the vertical direction. When clamping the circuit board and lifting the circuit board and the grabbing module 6 for movement by the mechanical hand, the elastic telescopic member 23 tightly pushes down the circuit board, cooperates with the lower groove wall of the groove structure 22, and limits the circuit board in the vertical direction. This ensures that the circuit board does not deviate due to gravity during clamping and movement, resulting in unstable clamping and falling.

[0036] In the present embodiment, the driving plate 18 has a T-shaped assembly portion 26 at one end connected with the clamping plate 19, and the clamping plate 19 has an assembly groove 27 matched with the assembly portion 26 at one side connected with the driving plate 18. The driving plate 18 and the clamping plate 19 are connected by clamping the assembly portion 26 on the assembly groove 27, ensuring that the driving plate 18 and the clamping plate 19 can be stably assembled.

[0037] In some embodiments, the driving member 17 is provided with a sliding rail 25, and the sliding rail 25 is provided with sliding blocks opposite to each other. The driving plate 18 is at least partially connected with the sliding blocks, and the sliding blocks can move close to or away from each other on the sliding rail 25 to control the clamping or releasing action of the clamping plate 19. Specifically, the driving member 17 drives the sliding blocks to move on the sliding rail 25, ensuring the stability of the clamping force of the clamping plate 19 on both sides. In the present embodiment, the driving member 17 can be an element such as a gas cylinder or a lead screw motor that can provide driving force, which is not limited herein.

[0038] In the above embodiment, the circuit board feeding and discharging device further comprises a lens 7 for detecting the feeding of the circuit board. The lens 7 is provided opposite to the grabbing module 6 on the mounting plate 5. Specifically, after clamping the circuit board and placing the circuit board on the carrier 3 to complete the feeding, the lens 7 takes a photo of the circuit board to detect whether the circuit board is placed in place on the carrier 3, facilitating the normal progress of the next process.

[0039] In some embodiments, a plurality of limiting columns 9 and a plurality of positioning columns 10 are arranged on the carrier 3, the limiting columns 9 enclose a first station 11 for placing the circuit board, and the positioning columns 10 are used to position the circuit board on the first station 11. Specifically, when the circuit board is fed, the circuit board is clamped and placed on the first station 11, and the positioning columns 10 extend into the assembly holes of the circuit board to position the circuit board, so as to ensure that the circuit board is placed in place. At the same time, when the lens 7 is detected, the lens 7 takes a photo of the circuit board, and the control system can determine whether the circuit board is placed in place according to whether the positioning columns 10 are on the assembly holes in the photo.

[0040] It can be understood that the circuit board needs to be fed or unloaded according to production requirements. In the present application, a feeding platform 8 is further arranged on the rack 1, which can be used to place the circuit board to be fed or the circuit board after unloading. A plurality of limiting blocks 13 are arranged on the feeding platform 8, which enclose a second station 14 for placing the circuit board. The bottom of the feeding platform 8 is further provided with a second sensor 16 for sensing the circuit board. Specifically, the feeding platform 8 has a gap 15 at the position of the sensing head of the second sensor 16, so that the sensing light can detect whether the circuit board is placed on the feeding platform 8. When unloading, the mechanical hand control grabbing module 6 moves from the carrier 3 to clamp the circuit board and then moves to the feeding platform 8. The grabbing module 6 places the circuit board on the second station 14. When feeding, the mechanical hand control grabbing module 6 clamps the circuit board on the second station 14 and moves to place it on the carrier 3. The second sensor 16 detects whether there is a circuit board on the feeding platform 8 to control the movement sequence of the mechanical hand and perform feeding or unloading operation.

[0041] It should be noted that during the unloading process, the circuit board may be rejected due to detection failure in the previous process, and the carrier 3 may be empty, i.e., there is no circuit board on the carrier 3. In the present application, a first sensor 24 for sensing the circuit board is further arranged on the driving member 17. The first sensor 24 detects whether there is a circuit board on the carrier 3, so as to determine whether the mechanical hand needs to perform subsequent operation. When the first sensor 24 detects that there is no circuit board on the carrier 3 and the second sensor 16 detects that there is no circuit board on the feeding platform 8, the mechanical hand does not need to perform operation and waits for the next carrier 3.

[0042] In the present embodiment, during the feeding process, a third sensor 12 for detecting the height of the circuit board on the carrier 3 is arranged on one side of the conveying platform 2. When the circuit board is placed in place, the positioning columns 10 on the carrier 3 extend into the assembly holes of the circuit board to position the circuit board. At this time, the height of the circuit board on the carrier 3 is lower than the setting height of the third sensor 12, which determines that the circuit board is placed in place. If the circuit board is not placed in place, the height of the circuit board on the carrier 3 is higher than the setting height of the third sensor 12, and the third sensor 12 detects that the circuit board is not placed in place.

[0043] To sum up, in the circuit board feeding and discharging device provided by the application, the driving members 17 drive the driving plates 18 to move close to or away from each other, drive the clamping plates 19 to move synchronously, and drive the clamping portions 21 to move close to or away from each other to realize clamping or releasing of the circuit board. The mechanical arm 4 can drive the grabbing module 6 to move to realize grabbing, feeding or discharging of the circuit board, improve the production efficiency, and ensure the stability of the clamping force during the feeding and discharging process of the circuit board, avoid the circuit board from falling off during the clamping and moving process, and reduce the risk of damage to the circuit board.

[0044] The above embodiments only exemplarily illustrate the principles and effects of the application, and are not used to limit the application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and category of the application.
