Description

Technical Field

[0001] This utility model belongs to the field of welding tooling technology, and in particular relates to an auxiliary tooling for circuit board welding. Background Technology

[0002] In the circuit board manufacturing process, electronic components are inserted one by one onto the circuit board, and then the pins of the electronic components are soldered. During the above process, the circuit board needs to be placed on a soldering fixture, which fixes the processing position of the circuit board before soldering.

[0003] Regarding auxiliary tooling for circuit board soldering, a search of existing technology reveals a utility model patent with Chinese patent authorization announcement number CN220278528U, which discloses a soldering tooling for circuit boards. This tooling mainly includes a base, a limiting platform connected to the base via a telescopic rod, and limiting posts on the left and right sides of the base connected by springs. Pressure plates are located on the upper side of the limiting platform on both sides of the base. In use, the circuit board is clamped onto the limiting platform, and then soldering is performed on the circuit board.

[0004] In the prior art, welding fixtures similar to the above-mentioned existing technical solutions have been found to have areas for improvement in actual implementation: the limiting posts on both sides of the base are elastically set on both sides of the base by springs, which can easily cause the clamping to be loose when the width of the circuit board is small, and can easily cause the circuit board to not fit when the width of the circuit board is large. Overall, the range of circuit board widths that can be clamped is relatively small. Utility Model Content

[0005] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a circuit board welding auxiliary tooling, which solves the problem that the width range of the circuit boards that can be clamped in the existing circuit board welding auxiliary tooling is relatively small.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a circuit board welding auxiliary fixture, including a base, wherein there are two bases, the bases are made of rectangular tubes, the two bases are arranged parallel to each other on the left and right, each base is detachably connected to a base plate, and a rectangular sleeve is fixedly connected above each base plate. Both rectangular sleeves can be slidably fitted onto a support rod, and a support seat is fixed above each rectangular sleeve. Each support seat is provided with a clamping clamp on one side facing each other, the two clamping clamps are symmetrically arranged, and the clamping clamps are rotatably adjustable and elastically extendable and retractable on the support seat. A base support for placing a soldering gun or soldering iron is provided above one side of the support rod.

[0007] As a further improvement of this utility model, the base plate is detachably connected to the support rod by screws.

[0008] As a further improvement of this utility model, each of the rectangular sleeves is threaded with a first tightening bolt, one end of which rests against the support rod.

[0009] As a further improvement of this utility model, each rectangular sleeve is provided with a thickened block on the front side, and the first tightening bolt is threadedly connected to the thickened block.

[0010] As a further improvement of this utility model, a circular sleeve is rotatably connected to the support base at the position where the clamping clip is set. A second tightening bolt is threaded onto the support base and presses against the circular sleeve. A sliding shaft is slidably connected to the end of the circular sleeve away from the support base. The end of the sliding shaft away from the support base is connected to the clamping clip. A spring is fixedly connected between the clamping clip and the support base. The spring is sleeved on the outside of the sliding shaft and the circular sleeve.

[0011] As a further improvement of this utility model, each of the two clamping clamps has a clamping groove on its opposite side.

[0012] As a further improvement of this utility model, the support rod is made of a rectangular tube.

[0013] As a further improvement of this utility model, the base is made of a round rod that is spirally bent into a cup shape, and the bottom of the base is connected to the support rod by screws.

[0014] As a further improvement of this utility model, a foot is provided at both the front and rear ends of the base.

[0015] Compared with the prior art, this utility model has the following advantages: 1. By setting the circuit board welding auxiliary tooling device as a base, rectangular sleeve, support rod, support sleeve and clamping clamp, when welding circuit boards, according to the width of this batch of circuit boards, the distance between the two rectangular sleeves is changed by sliding the rectangular sleeve, and then the clamping clamp is compressed to clamp the two circuit boards between the two clamping clamps. Because the position of the two clamping clamps can be adjusted over a wide range by sliding the rectangular sleeve, when the width of the circuit board does not change much, the elasticity of the clamping clamp can be adjusted adaptively. When the width of the circuit board changes significantly, the distance between the two rectangular sleeves can be adjusted so that the clamping clamp can hold the circuit board, greatly increasing the clamping range of the circuit board.

[0016] In addition, the clamping clamp of this device can be rotated and adjusted, so the angle of the circuit board can be changed. For example, when the worker is sitting and soldering, the circuit board can be adjusted so that the circuit board surface is tilted towards the worker, which facilitates soldering and reduces fatigue.

[0017] In addition, by setting a base on the support rod, the soldering gun or soldering iron can be supported.

[0018] 2. By setting the detachable connection of the base plate on the support rod, the processing, manufacturing and assembly of the base plate are facilitated.

[0019] 3. By threading the first tightening bolt onto the rectangular sleeve, the rectangular sleeve can be locked onto the support rod. A thickening block is provided on the front side of the rectangular sleeve, and the first tightening bolt is threadedly connected to the thickening block, thus increasing the threaded connection length of the first tightening bolt and improving the connection firmness of the first tightening bolt.

[0020] 4. A circular sleeve is rotatably connected to the support base and locked by a second tightening bolt, thus allowing adjustment of the clamping angle and consequently the circuit board angle. A sliding shaft is slidably connected to the circular sleeve, which is connected to the clamping clamp. Springs are fitted around the outside of the circular sleeve and the sliding shaft, allowing the clamping clamp to elastically extend and retract left and right.

[0021] 5. By providing a clamping groove on each of the two opposing sides of the clamping clamp, the circuit board can be clamped in the clamping grooves of the two clamping clamps. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0024] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0025] This utility model discloses an auxiliary tooling for circuit board soldering. (Refer to...) Figure 1A circuit board soldering auxiliary fixture includes two bases 1, each made of rectangular tubing, arranged parallel to each other on the left and right sides. Each base 1 has a foot 16 fixedly installed at both its front and rear ends. A base plate 2 is detachably connected to the top of each base 1. Specifically, the base plate 2 is detachably connected to a support rod 4 via screws 8. This detachable connection of the base plate 2 to the support rod 4 facilitates its processing, fabrication, and assembly.

[0026] Each base plate 2 is fixedly connected to a rectangular sleeve 3. Both rectangular sleeves 3 can slide left and right onto a support rod 4, which is made of rectangular tubing. Each rectangular sleeve 3 is fixedly connected to a support base 5. Each support base 5 has a clamping clip 6 on its facing side. The two clamping clips 6 are symmetrically arranged and are rotatably adjustable and elastically extendable left and right on the support base 5. The clamping clips 6 of this device can be rotated and adjusted, thus changing the angle of the circuit board. For example, when a worker is sitting while welding, the circuit board can be adjusted so that the board surface is tilted towards the worker, reducing fatigue during welding.

[0027] In addition, each of the two clamping clips 6 has a clamping groove 15 on its opposite side. By having a clamping groove 15 on each of the clamping clips 6 on its opposite side, the circuit board can be clamped in the clamping groove 15 of the two clamping clips 6.

[0028] A base 7 for placing a soldering gun or soldering iron is provided above one side of the support rod 4. The base 7 is made of a round rod that is spirally bent into a cup shape, and its bottom is connected to the support rod 4 by screws 8. By providing the base 7 on the support rod 4, the soldering gun or soldering iron can be supported.

[0029] Furthermore, a circular sleeve 11 is rotatably connected to the support base 5 at each position where the clamping clip 6 is located. A second tightening bolt 12 is threaded onto the support base 5, and the second tightening bolt 12 abuts against the circular sleeve 11. A sliding shaft 13 is slidably connected to the end of the circular sleeve 11 furthest from the support base 5. The end of the sliding shaft 13 furthest from the support base 5 is connected to the clamping clip 6. A spring 14 is fixedly connected between the clamping clip 6 and the support base 5, and the spring 14 is sleeved on the outside of the sliding shaft 13 and the circular sleeve 11. By rotatably connecting the circular sleeve 11 to the support base 5 and locking it with the second tightening bolt 12, the angle of the clamping clip 6 can be adjusted, thereby adjusting the angle of the circuit board. The sliding shaft 13 is slidably connected to the circular sleeve 11, and the sliding shaft 13 is connected to the clamping clip 6. The spring 14 is sleeved on the outside of the circular sleeve 11 and the sliding shaft 13, allowing the clamping clip 6 to elastically extend and retract left and right.

[0030] Furthermore, each rectangular sleeve 3 is threadedly connected to a first tightening bolt 9, one end of which rests against the support rod 4. Each rectangular sleeve 3 has a thickening block 10 on its front side, and the first tightening bolt 9 is threadedly connected to the thickening block 10. By threading the first tightening bolt 9 onto the rectangular sleeve 3, the rectangular sleeve 3 can be locked onto the support rod 4. The presence of a thickening block 10 on the front side of each rectangular sleeve 3, with the first tightening bolt 9 threadedly connected to it, increases the threaded connection length of the first tightening bolt 9, thereby improving the connection strength of the first tightening bolt 9.

[0031] This utility model sets the circuit board welding auxiliary tooling device as a base 1, rectangular sleeve 3, support rod 4, support sleeve and clamping clamp 6. When welding circuit boards, according to the width of this batch of circuit boards, the distance between the two rectangular sleeves 3 is changed by sliding the rectangular sleeves 3, and then the clamping clamp 6 is compressed to clamp the two circuit boards between the two clamping clamps 6. Because the position of the two clamping clamps 6 can be adjusted over a wide range by sliding the rectangular sleeves 3, when the width of the circuit board does not change much, the elastic characteristics of the clamping clamp 6 can be adjusted adaptively. When the width of the circuit board changes significantly, the distance between the two rectangular sleeves 3 can be adjusted so that the clamping clamp 6 can clamp the circuit board, greatly increasing the clamping range of the circuit board.
