Description

Technical Field

[0001] The utility model relates to the field of splint transportation, in particular to a transportation mechanism for splints. Background Technique

[0002] A PCB automatic loading and unloading machine is a device that places a PCB board on a PCB production line or receives a PCB board from a PCB production line on a carrier. Taking the receiving machine as an example, after the PCB automatic receiving machine transports the PCB board on the production line to the receiving conveyor section, the receiving machine suction cup sucks up the PCB board and places it on the carrier. The production line's requirement for receiving the board is to ensure that the PCB board is placed on the carrier stably and quickly, without causing phenomena such as board jamming, board dropping, and board scratching.

[0003] The suction cup mechanism of the existing automatic receiving machine realizes board suction by means of an independent vacuum generator plus a suction nozzle. During the board receiving process, the vacuum generator generates vacuum, sucks the board surface through the suction nozzle, and then receives the board. Due to the large differences in the board surface structures of different processes, the differences in the board surface structures are manifested in the unevenness of the board surface, the presence of through holes of different sizes on the board surface, and the easy scratching of the board surface, etc., which will cause phenomena such as vacuum breakage, board scratching, and insecure adsorption when the suction nozzle adsorbs the board surface, resulting in phenomena such as board dropping, board jamming, and board surface damage.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0030] As Figures 1-7 ;

[0031] It includes a frame 1. A conveyor belt 2 is installed at the front end of the frame 1. A moving assembly 100 is provided on the frame 1, and the moving assembly 100 can support and move the PCB board; A clamping plate assembly 200 is also provided on the frame 1, and the clamping plate assembly 200 can clamp and support the PCB board;

[0032] The moving component 100 includes a first motor 3, a first synchronous pulley 4, and a second synchronous pulley 5. The first motor 3, the first synchronous pulley 4, and the second synchronous pulley 5 are respectively installed on the front side of the right end of the frame 1. The first synchronous pulley 4 and the second synchronous pulley 5 are connected by belt drive. The first motor 3 drives the first synchronous pulley 4 to rotate, and the first synchronous pulley 4 rotates synchronously with the second synchronous pulley 5 through the belt.

[0033] Further, there are two second synchronous pulleys 5, and a first synchronous belt 7 is connected between the second synchronous pulleys 5. After the second synchronous pulleys 5 rotate, they drive the first synchronous belt 7 to drive, so that the first synchronous belt 7 drives the first support seat 8 to move up and down. The first support seat 8 is installed on the first synchronous belt 7. The first support seat 8 and the second support seat 17 are used to support the clamping plate assembly 200 to move up and down to adjust the height. The rear end of the first support seat 8 slides on the frame 1 to guide the sliding of the first support seat 8.

[0034] Further, a third synchronous pulley 9 and a fourth synchronous pulley 12 are respectively installed at the upper end of the first support seat 8. A second synchronous belt 10 is connected between the third synchronous pulley 9 and the fourth synchronous pulley 12. A second motor 11 is also installed at the upper end of the first support seat 8. The output end of the second motor 11 is connected to the fourth synchronous pulley 12. The second motor 11 is used to drive the fourth synchronous pulley 12 to rotate. The fourth synchronous pulley 12 and the third synchronous pulley 9 rotate to drive the second synchronous belt 10 to drive. Through the drive of the second synchronous belt 10, the clamping plate assembly 200 is driven to move horizontally to adjust the position.

[0035] Further, sixth synchronous pulleys 15 are symmetrically installed on the front side of the left end of the frame 1. When the sixth synchronous pulleys 15 rotate, they drive the third synchronous belt 16 to drive. The third synchronous belt 16 is installed between the sixth synchronous pulleys 15. Through the drive of the third synchronous belt 16, the second support seat 17 is driven to move up and down. A first connecting rod 6 is installed between the sixth synchronous pulley 15 and the second synchronous pulley 5. When the second synchronous pulley 5 rotates, it also drives the first connecting rod 6 to rotate. The first connecting rod 6 drives the sixth synchronous pulley 15 to rotate, so that the sixth synchronous pulley 15 and the second synchronous pulley 5 rotate synchronously, so that the first support seat 8 and the second support seat 17 move up and down synchronously.

[0036] Further, a guide rail 20 is also installed on the front side of the left end of the frame 1. The second support seat 17 is installed on the third synchronous belt 16. The rear end of the second support seat 17 is slidably connected to the guide rail 20 to guide the sliding of the second support seat 17 through the guide rail 20.

[0037] Further, a seventh synchronous pulley 18 and a fifth synchronous pulley 13 are respectively installed at the upper end of the second support base 17. The seventh synchronous pulley 18 and the fifth synchronous pulley 13 rotate synchronously to drive the fourth synchronous belt 19 to transmit. The fourth synchronous belt 19 is installed between the seventh synchronous pulley 18 and the fifth synchronous pulley 13 for transmission, and the fourth synchronous belt 19 drives the clamping plate assembly 200 to move back and forth. A second connecting rod 14 is installed between the fifth synchronous pulley 13 and the fourth synchronous pulley 12, and the fourth synchronous pulley 12 drives the fifth synchronous pulley 13 to rotate synchronously through the second connecting rod 14;

[0038] Further, a first infrared sensor 21 and a second infrared sensor 22 are respectively installed at the front end of the frame 1. The first infrared sensor 21 and the second infrared sensor 22 are respectively arranged at both ends of the conveyor belt 2. The first infrared sensor 21 senses that the PCB board enters the conveyor belt 2, and the second infrared sensor 22 senses that the PCB board moves to the right end of the conveyor belt 2;

[0039] Further, the clamping plate assembly 200 includes a static clamping plate 23, a first connecting block 24 and a second connecting block 26. The static clamping plate 23 is installed between the first connecting block 24 and the second connecting block 26. The first connecting block 24 is installed on the second synchronous belt 10, and the second connecting block 26 is installed on the fourth synchronous belt 19. The first connecting block 24 and the second connecting block 26 move synchronously to drive the static clamping plate 23 and the moving clamping plate 31 to move;

[0040] Further, a cylinder 25 is installed at the end of the first connecting block 24. The cylinder 25 is used to push and pull the moving plate 28. The output end of the cylinder 25 is connected to the moving plate 28. Since the moving plate 28 is pushed and pulled, the bolt 30 slides in the chute 29. When the moving plate 28 is pushed, the bolt 30 supports the moving clamping plate 31 to move away from the static clamping plate 23, so that the space between the static clamping plate 23 and the moving clamping plate 31 opens. When the moving plate 28 is pulled, the bolt 30 supports the moving clamping plate 31 to approach the static clamping plate 23, so that the static clamping plate 23 and the moving clamping plate 31 approach each other to clamp the upper edge of the PCB board. Finally, it supports the PCB board to rise and move to the next process. A chute 29 is opened on the moving plate 28. The chute 29 is inclined to guide the movement of the bolt 30. The bolt 30 is slidably arranged in the chute 29. The movement of the bolt 30 drives the moving clamping plate 31 to move away from and close to the static clamping plate 23. The lower end of the bolt 30 is threadedly installed with the moving clamping plate 31. A limiting block 27 is installed at the bottom of the second connecting block 26. The upper edge of the PCB board is clamped and supported by the static clamping plate 23 and the moving clamping plate 31. Teflon is sprayed on the static clamping plate 23 and the moving clamping plate 31 to prevent the clamping jaws from damaging the surface of the PCB board. Although the surface of the board is uneven and there are through holes of different sizes, the static clamping plate 23 and the moving clamping plate 31 clamp the edge of the board, which will not affect the clamping force and thus will not cause the phenomenon of the board falling off.

[0041] The working principle of the present utility model is as follows: Adjust the height position of the limit block 27, place the PCB board on the conveyor belt 2, the lower end of the PCB board is limited and conveyed by the limit block on the conveyor belt 2, and the upper end of the PCB board is inserted into the limit block 27 for limit conveyance. When the second infrared sensor 22 senses the PCB board, the conveyor belt 2 stops working, the cylinder 25 pulls the moving plate 28, and the bolt 30 supports the moving clamping plate 31 to approach the static clamping plate 23. By approaching between the static clamping plate 23 and the moving clamping plate 31, the upper edge of the PCB board is clamped and supported. The first motor 3 drives the first synchronous pulley 4 to rotate, the first synchronous pulley 4 drives the second synchronous pulley 5 to rotate through the belt, the second synchronous pulley 5 drives the first connecting rod 6 to rotate, and also drives the first synchronous belt 7 to drive. The first connecting rod 6 drives the sixth synchronous pulley 15 to rotate, and the sixth synchronous pulley 15 drives the third synchronous belt 16 to drive. Thus, the first synchronous belt 7 and the third synchronous belt 16 are synchronously driven, respectively supporting the first support seat 8 and the second support seat 17 to rise synchronously, driving the PCB board to rise. The second motor 11 drives the fourth synchronous pulley 12 to rotate, the fourth synchronous pulley 12 drives the second synchronous belt 10 to drive, the fourth synchronous pulley 12 also drives the second connecting rod 14 to rotate, the second connecting rod 14 drives the fifth synchronous pulley 13 to rotate, and the fifth synchronous pulley 13 drives the fourth synchronous belt 19 to drive. Thus, the second synchronous belt 10 and the fourth synchronous belt 19 are synchronously driven, thereby driving the clamping plate assembly 200 to move back and forth to the next process, so as to directly clamp the edge of the PCB board without adsorbing the board surface, avoiding board dropping, board jamming, and sucking damage to the PCB board surface, and at the same time enabling the PCB board to be stably and quickly collected.

[0042] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present utility model can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
