[0002] Printed circuit boards, also known as PCB boards, require glue dispensing during their production process. Currently, PCB boards are mainly glued by special glue dispensing machines. When the glue dispensing machine is working, the PCB board is first conveyed to the corresponding position through a conveyor belt, and then the PCB board is clamped and fixed by a clamping mechanism, and finally glue is dispensed on the fixed PCB board. However, most of the current clamping mechanisms are hydraulically driven or cylinder driven. The clamping plate or clamping block of the clamping mechanism is easy to collide with the PCB board during the clamping process, thereby causing damage to the PCB board. In severe cases, it may even cause the PCB board to be scrapped, increasing the production cost of the PCB board. Summary of the invention

[0022] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1 to 5 As shown, a plate positioning and clamping device is a preferred embodiment of the present invention. The plate positioning and clamping device comprises a lifting mechanism, a top plate 1, a pushing mechanism, a vertical plate 4 and an elastic baffle 6. The top plate 1 is fixed to the driving end of the lifting mechanism. The pushing mechanism comprises a guide block 2 and a guide rod 5 of a guide assembly. One end of the guide rod 5 is fixedly connected to the vertical plate 4 and the other end is provided with a buffer assembly. The buffer assembly comprises a guide sleeve 3 slidably assembled at the end of the guide rod 5 and a buffer spring arranged in the guide sleeve 3. The top plate 1 is used to push the buffer assembly to realize the driving of the guide rod 5. The vertical plate 4 is used to clamp and fix with the elastic baffle 6 to realize the clamping and positioning of the material.

[0024] Specifically, the lifting mechanism in this embodiment is a scissor-type lifting mechanism, which is fixed below the top plate 1. The lifting and lowering of the lifting mechanism can realize the lifting and lowering drive of the top plate 1. Since the scissor-type lifting mechanism is a prior art, it is not described in detail in this embodiment. In this embodiment, the top plate 1 is in the shape of a strip plate, and there are two top plates 1. The two top plates 1 are arranged in parallel and spaced apart. In this embodiment, the two top plates 1 are fixedly connected to the driving end of the lifting mechanism. Specifically, the two top plates 1 can be fixed on the same plate, and the lifting mechanism can be fixed below the plate. The plate is driven to move by the lifting mechanism, so that the two top plates 1 can be driven synchronously. In other embodiments, the lifting mechanism can also be a screw drive mechanism, a hydraulic cylinder drive mechanism, an electric push rod, etc.

[0025] In this embodiment, there are two vertical plates 4, which are spaced apart and respectively located above the ends of the top plates 1, that is, the two vertical plates 4 and the two top plates 1 form a square frame as a whole, and the two top plates 1 are located below the two vertical plates 4. In this embodiment, two pushing mechanisms are respectively arranged on the same vertical plate 4, and the two pushing mechanisms are arranged above the corresponding ends of the two top plates 1 in a one-to-one correspondence. In this embodiment, the pushing mechanism includes a guide block 2 and a guide rod 5. The guide block 2 is in the shape of a rectangular parallelepiped. A guide hole for the guide rod 5 to pass through is provided in the guide block 2. In this embodiment, the top end of the guide rod 5 is connected and fixed to the vertical plate 4, and the connection and fixing method is specifically bolt or screw connection. The bottom end of the guide rod 5 is provided with a buffer assembly. In this embodiment, the buffer assembly includes a guide sleeve 3 and a buffer spring. The guide sleeve 3 is guided and slidably assembled on one end of the guide rod 5. An inner hole for the guide rod 5 to slide is provided in the guide sleeve 3. The buffer spring is placed in the inner hole of the guide sleeve 3. One end of the buffer spring is used to press against the guide rod 5, and the other end is used to press against the guide sleeve 3. In this way, when the guide sleeve 3 is pushed, the buffer spring will be squeezed at the same time, thereby playing a role in buffering the guide sleeve 3 and the guide rod 5 to move upward.

[0026] In order to limit the maximum upward movement of the guide rod 5, the diameter of the guide sleeve 3 in this embodiment is larger than the diameter of the guide rod 5, so that the guide sleeve 3 will stop and limit with the hole edge of the guide hole in the guide block 2. In this embodiment, the end surface of the guide sleeve 3 used to stop and limit with the hole edge of the guide hole constitutes a stop structure in this embodiment. In order to further enhance the buffering effect, in this embodiment, a second buffer pad is fixed on the end surface of the guide sleeve 3 facing the top plate 1, and the material of the second buffer pad is rubber or silicone.

[0027] In order to enhance the guiding function of the vertical plate 4, a plurality of guide rails 10 are provided on the side of the vertical plate 4 in this embodiment. Figure 5 As shown, in this embodiment, the guide rail 10 structure includes a guide groove 9 and a guide rail 10. The guide rail 10 is guided and slidably assembled in the guide groove 9. The guide rail 10 is connected and fixed to the vertical plate 4 by screws. The guiding and limiting effect of the guide rail 10 and the guide groove 9 enhances the guiding property of the vertical plate 4. In this embodiment, a linear bearing is also provided on the groove wall of the guide groove 9, so as to reduce the friction between the guide rail 10 and the guide groove 9. Since the guide rail 10 needs to slide up and down in the guide groove 9, in order to avoid the rigid contact between the two ends of the guide rail 10, in this embodiment, a first buffer pad 11 is also provided at both ends of the guide rail 10. In this embodiment, the material of the first buffer pad 11 is plastic.

[0028] In this embodiment, the elastic baffle 6 can be detachably mounted on the fixing plate 7. Figure 1 As shown, the fixing plate 7 is a long strip, and a plurality of fixing holes for fixing the elastic baffle 6 are arranged on the fixing plate 7, and the fixing holes are arranged at intervals along the extension direction of the fixing plate 7. In this embodiment, the elastic baffle 6 is fixed to the fixing plate 7 by screws, and in order to adjust the extension length and azimuth angle of the elastic baffle 6, a waist-shaped hole 8 for the bolt to pass through is arranged on the elastic baffle 6 in this embodiment.

[0029] In this embodiment, the fixed plate 7 is fixed on the outer plate, and the outer plate is located below the fixed plate 7 and on the outer side of the vertical plate 4 (the side of the two vertical plates 4 facing each other is the inner side, and the side away from each other is the outer side). In this embodiment, the guide block 2 and the guide groove 9 of the guide rail 10 structure are also fixed on the side of the outer plate.

[0030] The working process of the present invention is as follows: when it is necessary to clamp and position the material (the PCB board in this embodiment), the PCB board is first conveyed to the top of the two vertical plates 4 by the conveyor belt, and then the lifting mechanism is started. The lifting mechanism will lift up the two top plates 1, and the two top plates 1 will first contact the buffer components of the four pushing mechanisms and continue to push the guide sleeves 3 upward. The buffer springs in the guide sleeves 3 will be compressed, and the guide rods 5 will drive the vertical plates 4 upward under the action of the buffer springs until the two vertical plates 4 push the PCB board to the corresponding elastic baffles 6 positions, and the clamping and positioning of the PCB board is achieved through the clamping action of the two vertical plates 4 and the elastic baffles 6.

[0031] In summary, the embodiment of the present invention provides a plate positioning and clamping device. Since a buffer assembly is provided at one end of the guide rod 5, the buffer spring of the buffer assembly has an energy storage and buffering effect when compressed, thereby avoiding the situation where the material is easily damaged when the kinetic energy of the vertical plate 4 is large. In addition, the elastic baffle 6 and the second buffer pad in the present invention also have a certain elastic deformation performance, further avoiding the problem of rigid collision with the material.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
