Description

Technical Field

[0001] This utility model relates to the field of jig technology, and more specifically, to a frame-welded bakelite jig. Background Technology

[0002] In the existing technology, when soldering PCB boards, bakelite fixtures are used to fix the PCB boards, and then external soldering equipment is used to solder the PCB boards. However, in order to fix the PCB boards stably, bakelite fixtures are required to fit the PCB boards tightly. However, the specifications of PCB boards vary depending on the application scenario. In the existing technology, in order to fit the PCB boards precisely, the specifications of the bakelite fixtures are also fixed. This makes it impossible to fix PCB boards of different specifications, which is not suitable for large-scale use. Utility Model Content

[0003] The purpose of this invention is to provide a frame-welded bakelite fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a frame-welded bakelite fixture, including a fixed plate, a limit support frame fixedly connected to the top of the fixed plate, a rotating frame movably connected to the top of the limit support frame, sliding grooves on both the left and right sides of the rotating frame, a sliding block slidably connected to the inner cavity of the sliding groove, a threaded rod connected to the inner cavity of the sliding block, a clamping frame movably sleeved on the surface of the threaded rod, the sliding block being able to move along the axial direction of the sliding groove, and the threaded rod having a degree of freedom of lifting;

[0005] The first groove is located at the bottom of the clamping frame. The second groove is located on the front side of the inner cavity of the rotating frame, near the first groove. The first groove and the second groove are arranged opposite to each other. A damping ring is fixedly connected to the side of the limiting support frame away from the rotating frame. The rotating shafts at both ends of the rotating frame are movably sleeved in the inner cavity of the damping ring. The rotating frame can rotate around the damping ring as the axis. An anti-slip strip is fixedly connected to the top of the rotating frame.

[0006] The beneficial effects of adopting the above technical solution are as follows: By rotating the threaded rod one, the threaded rod one rises slightly away from the clamping frame, thereby moving the clamping frame away from the anti-slip strip, allowing the clamping frame to move. Then, the clamping frame is moved, thereby changing the distance between the first and second grooves. Next, multiple PCB boards are placed side by side in the inner cavities of the first and second grooves. Then, the threaded rod one is tightened, causing the threaded rod one to fall slightly, thereby pressing the clamping frame, making the clamping frame fit tightly against the anti-slip strip, thus preventing the clamping frame from moving. This allows the gap to be adjusted according to the different specifications of PCB boards, thereby achieving the ability to fix PCB boards of different specifications.

[0007] As a further improvement of this utility model, a hinge frame is provided at the top of the rotating frame, and a rectangular frame is hinged to the top of the hinge frame. A spring assembly is fixedly connected to the side of the rectangular frame away from the first groove, and a pressure plate is fixedly connected to the side of the spring assembly away from the rectangular frame. A soft pad is fixedly connected to the side of the pressure plate close to the rectangular frame.

[0008] The beneficial effects of adopting the above technical solution are as follows: After the PCB board is fixed by the first groove and the second groove, the rectangular frame is rotated in the direction of the first groove. At this time, the pushing force of the spring assembly drives the soft pad to press the PCB board tightly, thereby supporting the PCB board.

[0009] As a further improvement of this utility model, a support column is fixedly connected to the top of the rotating frame, and a threaded rod is threadedly connected to the top of the support column, with a limit plate engaging the surface of the threaded rod.

[0010] The beneficial effects of adopting the above technical solution are as follows: before pressing the rectangular frame down, the threaded rod 2 is unscrewed, and then the limiting plate is pulled out. After the rectangular frame is pressed down, the limiting plate is then inserted into the inner cavity of the support column, and then the threaded rod 2 is screwed into the inner cavity of the support column to fix the limiting plate, thereby pressing and fixing the rectangular frame through the limiting plate.

[0011] As a further improvement of this utility model, a pull ring is fixedly connected to the side of the pressure plate away from the soft pad, a collection bin is fixedly connected to the side of the rotating frame away from the rotating frame, and a discharge pipe is fixedly connected to the side of the collection bin away from the rotating frame.

[0012] The beneficial effects of adopting the above technical solution are as follows: during the welding process, pulling the pull ring causes the pressure plate to move away from the rotating frame, thereby extending the spring assembly. Then, releasing the pull ring causes the pressure plate to move downward through the tension of the spring assembly, thereby causing the soft pad to knock and vibrate the PCB, thus shaking off the welding debris generated on its surface into the inner cavity of the collection chamber, and then discharging it through the discharge pipe.

[0013] As a further improvement of this utility model, the clamping frame is located above the anti-slip strip, and the clamping frame is fitted into the inner cavity of the rotating frame;

[0014] The beneficial effect of adopting the above technical solution is that, by positioning the clamping frame above the anti-slip strip, the clamping frame can fit tightly against the anti-slip strip after being pressed by the threaded rod, thus preventing the clamping frame from moving.

[0015] As a further improvement of this utility model, a limiting rod is provided at the top of the limiting support frame, and the rotating frame is placed at the top of the limiting support frame;

[0016] The beneficial effects of adopting the above technical solution are: by using the limiting post at the top of the limiting support frame, the rotating frame is limited by the limiting support frame when it is vertically erected, and by placing the rotating frame at the top of the limiting support frame, the rotating frame can be supported and fixed by the limiting support frame when it is horizontally placed.

[0017] As a further improvement of this utility model, the spring assembly consists of a damping telescopic rod and a spring, wherein the damping telescopic rod is located at the center of the spring cavity;

[0018] The beneficial effects of adopting the above technical solution are: by setting the spring, the soft pad can fit tightly against the PCB board downwards, thereby supporting the PCB board; and by using the damping telescopic rod located at the center of the spring cavity, the spring is prevented from shifting during deformation.

[0019] As a further improvement of this utility model, the soft pad is fitted into the inner cavity of the rectangular frame, and the collection chamber is a conical cavity.

[0020] The beneficial effects of adopting the above technical solution are: by fitting the soft pad into the inner cavity of the rectangular frame, the rectangular frame can position and guide the soft pad; and by using the cone-shaped cavity of the collection bin, the material is concentrated and guided downwards into the material pipe.

[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides a frame-welded bakelite fixture, including a fixed plate 1, a limiting support frame 2 fixedly connected to the top of the fixed plate 1, a rotating frame 3 movably connected to the top of the limiting support frame 2, and sliding grooves 4 on both the left and right sides of the rotating frame 3. A sliding block 5 is slidably connected to the inner cavity of the sliding groove 4, and a threaded rod 6 is threadedly connected to the inner cavity of the sliding block 5. A clamping frame 7 is movably sleeved on the surface of the threaded rod 6. The sliding block 5 can move along the axial direction of the sliding groove 4, and the threaded rod 6 has a degree of freedom of lifting.

[0030] Groove 1 8 is located at the bottom of clamping frame 7. Groove 2 9 is located on the front side of the inner cavity of rotating frame 3 near groove 1 8. Groove 1 8 and groove 2 9 are arranged opposite to each other. A damping ring 10 is fixedly connected to the side of limiting support frame 2 away from rotating frame 3. The rotating shafts at both ends of rotating frame 3 are movably sleeved in the inner cavity of damping ring 10. Rotating frame 3 can rotate around damping ring 10 as the axis. Anti-slip strip 11 is fixedly connected to the top of rotating frame 3.

[0031] The beneficial effects of adopting the above technical solution are as follows: By rotating the threaded rod 6, the threaded rod 6 rises slightly away from the clamping frame 7, thereby moving the clamping frame 7 away from the anti-slip strip 11, allowing the clamping frame 7 to move. Then, the clamping frame 7 is moved, thereby changing the distance between the groove 8 and the groove 9. Then, multiple PCB boards are arranged side by side in the inner cavity of the groove 8 and the groove 9. Then, the threaded rod 6 is tightened, causing the threaded rod 6 to fall slightly, thereby pressing the clamping frame 7, making the clamping frame 7 fit tightly against the anti-slip strip 11, thus preventing the clamping frame 7 from moving. This allows the gap to be adjusted according to the different specifications of PCB boards, thereby achieving the ability to fix PCB boards of different specifications.

[0032] In one embodiment of the present invention, a hinge frame 15 is provided at the top of the rotating frame 3, and a rectangular frame 16 is hinged at the top of the hinge frame 15. A spring assembly 17 is fixedly connected to the side of the rectangular frame 16 away from the groove 8. A pressure plate 18 is fixedly connected to the side of the spring assembly 17 away from the rectangular frame 16. A soft pad 20 is fixedly connected to the side of the pressure plate 18 close to the rectangular frame 16.

[0033] The beneficial effects of adopting the above technical solution are as follows: After the PCB board is fixed by the first groove 8 and the second groove 9, the rectangular frame 16 is rotated in the direction of the first groove 8. At this time, the pushing force of the spring assembly 17 drives the soft pad 20 to press the PCB board tightly, thereby supporting the PCB board.

[0034] In one embodiment of this utility model, a support column 12 is fixedly connected to the top of the rotating frame 3, and a threaded rod 13 is threadedly connected to the top of the support column 12, with a limit plate 14 engaging the surface of the threaded rod 13.

[0035] The beneficial effects of adopting the above technical solution are as follows: before pressing down on the rectangular frame 16, the threaded rod 13 is unscrewed, and then the limiting plate 14 is pulled out. After pressing down on the rectangular frame 16, the limiting plate 14 is inserted into the inner cavity of the support column 12, and then the threaded rod 13 is screwed into the inner cavity of the support column 12 to fix the limiting plate 14, thereby pressing and fixing the rectangular frame 16 through the limiting plate 14.

[0036] In one embodiment of this utility model, a pull ring 19 is fixedly connected to the side of the pressure plate 18 away from the soft pad 20, a collection bin 21 is fixedly connected to the side of the rotating frame 3 away from the rotating frame 3, and a discharge pipe 22 is fixedly connected to the side of the collection bin 21 away from the rotating frame 3.

[0037] The beneficial effects of adopting the above technical solution are as follows: during the welding process, pulling the pull ring 19 causes the pressure plate 18 to move away from the rotating frame 3, thereby causing the spring assembly 17 to extend. Then, when the pull ring 19 is released, the pressure plate 18 moves downward through the pulling force of the spring assembly 17, thereby causing the soft pad 20 to knock and vibrate the PCB, thereby shaking off the debris generated by the welding on its surface into the inner cavity of the collection chamber 21, and then discharging it through the discharge pipe 22.

[0038] In one embodiment of this utility model, the clamping frame 7 is located above the anti-slip strip 11, and the clamping frame 7 is attached to the inner cavity of the rotating frame 3.

[0039] The beneficial effect of adopting the above technical solution is that, since the clamping frame 7 is located above the anti-slip strip 11, the clamping frame 7 can fit tightly with the anti-slip strip 11 after being pressed by the threaded rod 6, thereby making the clamping frame 7 unable to move.

[0040] In one embodiment of this utility model, a limiting rod is provided at the top of the limiting support frame 2, and the rotating frame 3 is placed at the top of the limiting support frame 2.

[0041] The beneficial effects of adopting the above technical solution are: by using the limiting post at the top of the limiting support frame 2, the rotating frame 3 is limited by the limiting support frame 2 when it is vertically erected, and by placing the rotating frame 3 at the top of the limiting support frame 2, the rotating frame 3 can be supported and fixed by the limiting support frame 2 when it is horizontally placed.

[0042] In one embodiment of this utility model, the spring assembly 17 consists of a damping telescopic rod and a spring, with the damping telescopic rod located at the center of the spring cavity;

[0043] The beneficial effects of adopting the above technical solution are: by setting the spring, the soft pad 20 can be tightly attached to the PCB board downwards, thereby supporting the PCB board; and by using the damping telescopic rod located at the center of the spring cavity, the spring is prevented from shifting during deformation.

[0044] In one embodiment of this utility model, the soft pad 20 is attached to the inner cavity of the rectangular frame 16, and the collection chamber 21 is a conical cavity.

[0045] The beneficial effects of adopting the above technical solution are: by attaching the soft pad 20 to the inner cavity of the rectangular frame 16, the rectangular frame 16 can position and guide the soft pad 20, and by using the collection bin 21 as a conical cavity, the collection bin 21 can concentrate and guide the material in the direction of the downward material pipe 22.

[0046] The working principle and usage process of this utility model: unscrew the threaded rod 13 to remove the limiting plate 14;

[0047] Rotate the threaded rod 6. At this time, the threaded rod 6 and the sliding block 5 will make the threaded rod 6 rise, thereby reducing the pressure on the clamping frame 7 and separating the clamping frame 7 from the anti-slip strip 11. Then, adjust the distance between the clamping frame 7 and the groove 9 to match the size of the PCB board to be soldered. Then, place multiple PCB boards side by side into the inner cavity of the groove 8 and the groove 9. Then, rotate and tighten the threaded rod 6 again, so that the threaded rod 6 will press the clamping frame 7 down again, so that the clamping frame 7 is in contact with the anti-slip strip 11, thereby fixing the position of the clamping frame 7 and fixing multiple PCB boards.

[0048] Next, the rectangular frame 16 is placed down towards the PCB board, so that the soft pad 20 contacts and adheres to the PCB board. Then, the limiting plate 14 is inserted into the inner cavity of the support column 12, and then the threaded rod 13 is screwed into the inner cavity of the limiting plate 14 again, so as to fix the limiting plate 14. At this time, the limiting plate 14 contacts the rectangular frame 16 and fixes the rectangular frame 16.

[0049] Next, rotate the rotating frame 3 so that its bottom end faces the front of the limiting support frame 2, and limit the rotating frame 3 by the top end of the limiting support frame 2, making the rotating frame 3 vertical and exposing the PCB board. Then, use external welding equipment to weld the PCB board. During the welding process, pull the pull ring 19 to extend the spring assembly 17, and release the pull ring 19. The spring assembly 17 pulls the pressure plate 18 to move towards the rectangular frame 16, thereby vibrating the PCB board through the soft pad 20, causing the debris generated during the welding process on the PCB board to fall off. The fallen debris falls into the inner cavity of the collection chamber 21 and is discharged through the discharge pipe 22 at the bottom of the collection chamber 21.
