Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a welding fixture for positioning signal ground metal parts. Background Technology

[0002] The positioning and soldering of signal ground metal components on the circuit board is a key pre-fixing process to ensure low impedance and high precision connection with the ground layer, thereby guaranteeing the signal integrity and high-frequency performance of the equipment. According to the existing technology, such as the circuit board soldering fixture box disclosed in Chinese patent document CN209882280U, the drive motor half gear rotates. Due to the rotational characteristics of the half gear, the half gear meshes with the tooth groove in the strip opening, causing the moving plate to slide back and forth on the bottom wall of the box. This allows the heat dissipation device to evenly and quickly dissipate heat from the circuit board on the fixture plate. The battery powers the soldering machine, enabling the soldering machine to solder the circuit board on the fixture plate. The cooler cools the circuit board and delivers cold air to the heat dissipation plate. Multiple first heat dissipation holes and second heat dissipation holes cooperate to dissipate heat from the circuit board on the fixture plate.

[0003] According to its publicly available technical solutions, the existing technology involves placing the circuit board inside the fixture for stability, then adjusting the positioning component to the corresponding position of the circuit board for welding. When the welding is completed and the next circuit board needs to be replaced for processing, the welding position of the circuit board needs to be repositioned. This process is cumbersome and time-consuming, and frequent manual adjustments can easily lead to slight deviations in positioning. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a positioning and welding fixture for signal ground metal parts, thereby solving the problems mentioned in the background. This invention uses an installed release mechanism to displace the first strip block by pressing a short rod, which releases the locked state of the circuit board. After placing the next circuit board, the short rod is reset, allowing the positioning component to be quickly reset. This avoids the frequent manual unlocking and adjustment required in traditional fixtures, improves the efficiency of mass production, and prevents positioning deviations caused by multiple manual operations, thus ensuring continuous and efficient mass production.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a signal ground metal part positioning welding fixture, comprising a welding fixture body, the welding fixture body comprising a placement plate, a clamping assembly, a positioning assembly and a release mechanism, the surface of the placement plate having a groove, the end of the placement plate having a strip-shaped hole, the release mechanism being disposed inside the groove, the clamping assembly and the positioning assembly being disposed on the surface of the placement plate, and a second strip-shaped block being welded to the surface of the placement plate.

[0006] Furthermore, the clamping assembly includes a first strip block and a spring housing, wherein a protrusion is connected to the bottom surface of the first strip block and the protrusion is embedded inside the groove.

[0007] Furthermore, the end of the spring compartment is welded to the side of the shelf, and a spring is installed inside the spring compartment. One end of the spring is welded to the inner wall of the spring compartment, and the other end of the spring is welded to the surface of the protrusion.

[0008] Furthermore, the positioning component includes a T-shaped groove, a first sliding plate, a second sliding plate, and a sleeve. The T-shaped groove is formed on the surfaces of the first strip block and the second strip block, and the bottom surfaces of the first sliding plate and the second sliding plate are each connected to a T-shaped slider.

[0009] Furthermore, the T-shaped slider is embedded inside the T-shaped groove, and a first fixed post and a second fixed post are respectively welded to the top surfaces of the first sliding plate and the second sliding plate. A positioning rod is welded to the surface of the first fixed post, and a collar is welded to the top surface of the second fixed post.

[0010] Furthermore, the end of the positioning rod passes through the inside of the collar, the sleeve is fitted onto the surface of the positioning rod, a telescopic rod is welded to the surface of the sleeve, a positioning ring is welded to the surface of the telescopic rod, and magnetic strips are installed on the inner wall of the sleeve and the top surface of the positioning rod.

[0011] Furthermore, the disengagement mechanism includes a baffle, a cam, and a threaded rod. The baffle is embedded inside a groove, and a long rod is welded to the surface of the baffle. The end of the long rod passes through the side of the shelf, and an L-shaped rod is welded to the surface of the baffle.

[0012] Furthermore, the other end of the L-shaped rod is connected to the surface of the cam via a bearing. A short rod is welded to the surface of the cam, and the end of the short rod passes through the interior of the strip-shaped hole. A threaded hole is opened on the surface of the second strip-shaped block, and the threaded rod is inserted into the interior of the threaded hole. A handwheel is welded to the end of the threaded rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. This signal ground metal positioning welding fixture, through the installed clamping components, eliminates the need for adjustment devices when replacing circuit boards of different specifications. It can clamp circuit boards of different specifications simply by releasing the first strip block, avoiding the cumbersome operation of adjusting the clamp in the traditional method and improving clamping efficiency.

[0015] 2. The metal positioning welding fixture for this signal ground uses the installed positioning components to achieve rapid locking of the sleeve and positioning rod by utilizing the magnetic attraction between the sleeve and the positioning rod. It also ensures that the telescopic rod and the positioning ring always maintain a stable vertical downward position, preventing welding misalignment caused by angular tilt.

[0016] 3. The signal ground metal part positioning welding fixture, through the installed release mechanism, presses the short rod to move the first strip block, thereby releasing the locked state of the circuit board. After placing the next circuit board, the short rod is reset, which allows the positioning component to be quickly reset. This avoids the frequent manual unlocking and adjustment in traditional fixtures, improves the operation efficiency of mass production, prevents positioning deviations caused by multiple manual operations, and provides a guarantee for continuous and efficient mass production.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4This utility model provides the following technical solution: a signal ground metal component positioning and welding fixture, including a welding fixture body, the welding fixture body including a placement plate 1, a clamping component 2, a positioning component 3 and a release mechanism 4, the surface of the placement plate 1 is provided with a groove 8, the end of the placement plate 1 is provided with a strip hole 6, the release mechanism 4 is disposed inside the groove 8, the clamping component 2 and the positioning component 3 are disposed on the surface of the placement plate 1, the surface of the placement plate 1 is welded with a second strip block 26, after the circuit board is clamped by using the clamping component 2, the positioning component 3 is adjusted to the signal ground for welding, and after welding is completed, the circuit board can be quickly replaced by the release component.

[0024] In this embodiment, the clamping assembly 2 includes a first strip block 9 and a spring compartment 10. The bottom surface of the first strip block 9 is connected to a protrusion, which is embedded in the interior of the groove 8. The end of the spring compartment 10 is welded to the side of the shelf 1. A spring 23 is provided inside the spring compartment 10. One end of the spring 23 is welded to the inner wall of the spring compartment 10, and the other end of the spring 23 is welded to the surface of the protrusion. Pushing the first strip block 9 causes the spring 23 to enter a compressed state. After the circuit board is placed in the designated position on the shelf 1, the first strip block 9 is slowly released to complete the clamping of the circuit board.

[0025] In this embodiment, the positioning component 3 includes a T-shaped groove 24, a first sliding plate 11, a second sliding plate 14, and a sleeve 17. The T-shaped groove 24 is formed on the surfaces of the first strip block 9 and the second strip block 26. T-shaped sliders are connected to the bottom surfaces of both the first sliding plate 11 and the second sliding plate 14, and these sliders are embedded inside the T-shaped groove 24. A first fixing post 12 and a second fixing post 15 are welded to the top surfaces of the first sliding plate 11 and the second sliding plate 14, respectively. A positioning rod 13 is welded to the surface of the first fixing post 12, and a collar 1 is welded to the top surface of the second fixing post 15. 6. The end of the positioning rod 13 passes through the inside of the collar 16. The sleeve 17 is fitted onto the surface of the positioning rod 13. A telescopic rod 25 is welded to the surface of the sleeve 17. A positioning ring 19 is welded to the surface of the telescopic rod 25. Magnetic strips 18 are installed on the inner wall of the sleeve 17 and the top surface of the positioning rod 13. The first sliding plate 11 is pushed to move. The displacement of the first sliding plate 11 is linked to the synchronous displacement of the positioning rod 13. After the positioning rod 13 is adjusted to the transverse area of ​​the signal ground, the sliding sleeve 17 moves the positioning ring 19 above the signal ground and rotates the sleeve 17 to complete the positioning of the signal ground.

[0026] In this embodiment, the release mechanism 4 includes a baffle 22, a cam 21, and a threaded rod 5. The baffle 22 is embedded inside the groove 8. A long rod 7 is welded to the surface of the baffle 22, and the end of the long rod 7 passes through the side of the shelf 1. An L-shaped rod is welded to the surface of the baffle 22, and the other end of the L-shaped rod is connected to the surface of the cam 21 through a bearing. A short rod 20 is welded to the surface of the cam 21, and the end of the short rod 20 passes through the inside of the strip hole 6. A threaded hole is opened on the surface of the second strip block 26, and the threaded rod 5 is inserted into the inside of the threaded hole. A handwheel is welded to the end of the threaded rod 5. Pressing the short rod 20 towards the first sliding plate 11 causes the cam 21 to rotate, thereby causing the first sliding plate 11 to move, releasing the lock on the circuit board. Replacing the circuit board pushes the short rod 20 back to its original position, and the circuit board is clamped again.

[0027] Working principle: In the initial state, the end of the threaded rod 5 does not contact the top surface of the long rod 7, and the sleeve 17 and the magnetic strip 18 of the positioning rod 13 are misaligned. The first strip block 9 is pushed, causing it to move along the groove 8 on the surface of the shelf 1. The spring 23 enters the compressed state, placing the circuit board on one side of the second strip block 26 on the surface of the shelf 1, with the end of the circuit board flush with the edge of the groove 8 on the shelf 1. The first strip block 9 is slowly released, and it moves under the elastic force of the spring 23. When the first strip block 9 contacts the side of the circuit board, the clamping work of the circuit board is completed, pushing the first sliding plate 11 to move along the T-shaped groove 24. The displacement of the first sliding plate 11 drives the first fixed... The column 12 and the positioning rod 13 are displaced. The displacement of the positioning rod 13 causes the sleeve 17, the telescopic rod 25, the positioning ring 19, and the collar 16 to move synchronously. The displacement of the collar 16 causes the second fixed column 15 and the second sliding plate 14 to move. When the positioning rod 13 moves to the signal ground area on the circuit board, the displacement stops. At this time, the sleeve 17 is pushed to move along the positioning rod 13. The displacement of the sleeve 17 causes the telescopic rod 25 and the positioning ring 19 to move synchronously. When the positioning ring 19 reaches above the signal ground, the sleeve 17 is rotated so that the magnetic strip 18 on the inner wall of the sleeve 17 coincides with the magnetic strip 18 on the top surface of the positioning rod 13, so that the sleeve 17 enters the locked state, and the telescopic rod 25 is magnetically positioned. Always maintain a vertically downward position. Adjust the length of the telescopic rod 25 to lower the positioning ring 19 to a suitable welding height. Insert the cylindrical metal part into the positioning ring 19 for welding. When the metal part is welded to the signal ground surface, adjust the telescopic rod 25 to its initial height, causing the positioning ring 19 to disengage from the cylindrical shape. Push the baffle 22 to slide along the groove 8. The displacement of the baffle 22 causes the L-shaped rod, cam 21, long rod 7, and short rod 20 to move synchronously. When the cam 21 moves to the side contact with the T-shaped slider on the bottom surface of the first sliding plate 11, rotate the handwheel at the end of the threaded rod 5. The threaded rod 5 rotates and moves downward. When the displacement reaches the point where the end of the threaded rod 5 contacts the top surface of the long rod 7, stop rotating. At this time, the long rod 7... With the baffle 22 locked, press the short rod 20 against the first sliding plate 11 to rotate the cam 21. The rotation of the cam 21 causes the T-shaped slider in contact with the cam 21 to move. The movement of the T-shaped slider causes the first strip block 9 to move. The movement of the first strip block 9 releases the clamp on the circuit board, allowing the soldered circuit board to be pulled out and the next circuit board of the same specifications to be soldered to be placed. After placement, push the short rod 20 to reset. The movement of the short rod 20 causes the cam 21 to rotate to the initial position. The first strip block 9 returns to the initial position under the elastic force of the spring 23 to clamp the circuit board. After adjusting the length of the telescopic rod 25, insert the metal part into the positioning ring 19 for soldering. Repeat the above operation.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
