Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a multi-layer PCB stacking positioning fixture. Background Technology

[0002] PCB, also known as printed circuit board, serves as a support for electronic components. During PCB manufacturing, positioning fixtures are often used to clamp multiple raw materials for the PCB, and then the stacking components on the positioning fixtures are used to stack the multiple raw materials together.

[0003] Some existing positioning fixtures directly use screws to push the clamping plates to move and clamp multiple PCB raw materials. Then, stacking components installed on the clamping plates are used to stack the multiple PCB raw materials. However, because the positions of the stacking components are relatively fixed, the raw materials to be stacked cannot be placed between the clamping plates sequentially during the stacking process. The clamping plates must be opened before the raw materials are put in. When the clamping plates are opened, the multiple raw materials that have just been stacked together often lose their restraining force due to the short stacking time. The stress generated during the stacking process can cause them to expand outward. When they are clamped and fixed by the clamping plates at this time, they are prone to secondary deformation, which can cause embrittlement of the internal parts during repeated stress deformation, resulting in a decrease in the yield of the final product. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer PCB stacking positioning fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multilayer PCB stacking positioning fixture, including a mounting platform, a rotating handle on the mounting platform, a first bevel gear connected to the rotating handle, a second bevel gear movably fitted and meshing with the outer wall of the first bevel gear, the top end of the second bevel gear penetrating the mounting platform and connected to a gear plate, two translational gear plates movably fitted and meshing with the outer wall of the gear plate, a clamping plate fixedly installed at the top end of each translational gear plate, and a stacking assembly connected to the top ends of the two clamping plates.

[0006] Preferably, the stacking assembly includes two U-shaped frames, each with a rotating shaft rotatably mounted on it. A rotating plate is fixedly mounted on the outer wall of each rotating shaft. Each rotating plate has a movable groove, and a pressure rod is provided in each movable groove. A stacking block is fixedly mounted at the bottom end of each of the two pressure rods. The top ends of the two pressure rods are connected to a stacking plate. An L-shaped insert plate is fixedly mounted at the bottom end of each U-shaped frame.

[0007] Preferably, a fixing block is fixedly installed at the top of each U-shaped frame, the fixing block is provided with an opening, and a movable block is slidably installed in the opening of the fixing block. A connecting screw is provided on the movable block, and a limit plate is provided on the side of each of the two U-shaped frames that are close to each other.

[0008] Preferably, the top of the mounting platform is provided with four translation slots, and the bottom of each clamp is fixedly installed with a translation plate, and the width of the translation plate and the translation tooth plate is the same as the width of the translation slot.

[0009] Preferably, each of the clamps is provided with a T-slot, and an adjusting screw is rotatably installed in each of the T-slots. A sliding block adapted to the T-slot is movably fitted on the outer wall of each adjusting screw, and a fitting plate is fixedly installed on each sliding block.

[0010] Preferably, each of the two clamping plates has an insertion groove on the side wall on the side away from each other, and the length and width of the insertion groove are the same as the length and width of the long end of the L-shaped insertion plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By pulling the stacking plate upwards to disconnect it from the pressure rod, the L-shaped insert plate is pulled out of the insert slot on the clamping plate, causing the two U-shaped frames to detach from the top of the clamping plate. New material can then be placed between the two clamping plates. The L-shaped insert plate and the stacking plate are then reset in sequence to continue the stacking operation. This avoids the need to control the clamping of the raw materials by loosening the clamping plates until the stacked parts do not affect the insertion of new materials, thus speeding up work efficiency and improving the yield rate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-layer PCB stacking positioning fixture, including a mounting platform 1, a rotating handle 2 on the mounting platform 1, a first bevel gear 3 connected to the rotating handle 2, a second bevel gear 4 movably attached to the outer wall of the first bevel gear 3 and meshing therewith, the top of the second bevel gear 4 penetrating the mounting platform 1 and connected to a gear plate 24, two translational gear plates 6 movably attached to the outer wall of the gear plate 24 and meshing therewith, a clamping plate 8 fixedly installed at the top of each translational gear plate 6, and a stacking assembly 11 connected to the top of the two clamping plates 8. By controlling the rotation of the rotating handle 2 to rotate the first bevel gear 3, the first bevel gear 3 drives the gear plate 24 to rotate, causing the two translational gear plates 6 to move in translational grooves 5, and the clamping plates 8 located on the two translational gear plates 6 move closer to each other to clamp the PCB raw materials.

[0020] The stacking assembly 11 includes two U-shaped frames 12, which are movably fitted to the top of the clamping plate 8 to prevent the U-shaped frames 12 from being unable to be removed when adding raw materials between the two clamping plates 8. A rotating shaft 13 is rotatably mounted on each U-shaped frame 12, and a rotating plate 14 is fixedly mounted on the outer wall of each rotating shaft 13. Each rotating plate 14 has a movable groove 19, and a pressure rod 20 is installed within each movable groove 19. A stacking block 21 is fixedly mounted at the bottom of each of the two pressure rods 20, and a stacking plate 22 is connected to the top of both pressure rods 20. The bottom of the stacking plate 22 has two insertion holes matching the diameter of the pressure rods 20. This allows for easy removal of the stacking plate 22 from the top of the two pressure rods 20 during later use, enabling the removal of the two L-shaped insert plates 23. The bottom of the U-shaped frame 12 is fixedly equipped with L-shaped insert plates 23. Insertion slots are provided on the side walls of the two clamping plates 8 that are far apart from each other, and the length and width dimensions of the insertion slots are the same as the length and width dimensions of the long end of the L-shaped insert plate 23. By inserting the L-shaped insert plate 23 into the insertion slot on the clamping plate 8, the position of the U-shaped frame 12 can be fixed. Then, the pressure rods 20 are controlled to slide in the movable slot 19 until the stacking plate 22 and the pressure rods 20 can be inserted and connected together, so that the material can be stacked.

[0021] Each of the U-shaped frames 12 has a fixed block 15 fixedly installed at its top. The fixed block 15 has an opening, and a movable block 16 is slidably installed in the opening. The movable block 16 is provided with a connecting screw 17. Each of the two U-shaped frames 12 has a limit plate 18 on the side where they are close to each other. The top of each rotating plate 14 is provided with a threaded hole that matches the diameter of the connecting screw 17. By pushing the movable block 16 to slide on the fixed block 15 to adjust its position, and controlling the connecting screw 17 to pass through the movable block 16 and screw into the threaded hole on the rotating plate 14, the bottom of the rotating plate 14 is in contact with the limit plate 18, which can restrict the rotating plate 14 from continuing to rotate through the rotating shaft 13.

[0022] The top of the mounting platform 1 is provided with four translation slots 5, and the bottom of the clamping plate 8 is fixedly installed with translation plates 7. The width of the translation plates 7 and the translation toothed plates 6 is the same as the width of the translation slots 5, so that the translation plates 7 and the translation toothed plates 6 can move horizontally during use.

[0023] Each clamping plate 8 is provided with a T-slot, and an adjusting screw 9 is rotatably installed in each T-slot. A sliding block that matches the T-slot is movably fitted on the outer wall of each adjusting screw 9, and a bonding plate 10 is fixedly installed on each sliding block. By controlling the rotation of the adjusting screw 9, the bonding plates 10 on the two clamping plates 8 can be tightly attached to the raw material to perform secondary position correction, thereby achieving precise positioning and clamping.

[0024] Working principle: In use, first place two raw materials on the top of the mounting platform 1 and control the rotating handle 2 to rotate. During the rotation of the rotating handle 2, the two clamping plates 8 are brought closer together and clamped and positioned by the cooperation of the first bevel gear 3, the second bevel gear 4, the gear plate 24, and the translational gear plate 6. Then, control the adjusting screw 9 to rotate so that the bonding plate 10 can fit the raw material, and the stacking plate 22 can be connected to the pressure rod 20. By pressing the stacking plate 22, the stacking block 21 is used to stack the raw material. When it is necessary to add new material for stacking, pull the stacking plate 22 upward to disconnect it from the pressure rod 20. Pull the L-shaped insert plate 23 out of the insert slot on the clamping plate 8, and drive the two U-shaped frames 12 to detach from the top of the clamping plate 8. New material can then be placed between the two clamping plates 8. Then, reset the L-shaped insert plate 23 and the stacking plate 22 in sequence to continue the stacking operation.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
