Technical Field

[0001] This utility model relates to the field of circuit board welding fixture technology, specifically a circuit board fixing device for circuit board welding. Background Technology

[0002] When repairing and soldering circuit boards, the electronic components on the circuit board are uneven. If the circuit board is placed directly on the workbench, it will wobble and become unstable, affecting the soldering operation. Therefore, devices for fixing circuit boards have appeared on the market, which suspend and fix the circuit board in the air, thereby eliminating the impact of uneven electronic components on the stability of the circuit board.

[0003] There is a circuit board fixing device on the market that uses two clamps to clamp and fix the circuit board by bringing them close together. When disassembling, you only need to move the two clamps away from each other. However, this process requires frequent tightening or loosening of the clamps. Moreover, when performing batch operations on the same type of circuit board, the movement position of the clamps needs to be determined during the secondary fixing, which affects the operation efficiency. Based on this, a circuit board fixing device for circuit board soldering is provided. Utility Model Content

[0031] 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.

[0032] Please see Figures 1-4 In this embodiment of the present invention, a circuit board fixing device for circuit board welding includes a bracket assembly 1 consisting of a base frame 101, a T-shaped rail 102, a slide block 103, a convex column 105, and a first locking bolt 106, as well as a clamping assembly 2. Two base frames 101 are symmetrically fixed to the bottom ends of the T-shaped rail 102, and the base frames 101 and the T-shaped rail 102 are perpendicularly distributed. The slide block 103 is slidably mounted on the outside of the T-shaped rail 102. The first locking bolt 106 is threadedly connected to the outside of the slide block 103 and penetrates through the slide block 103, tightly fitting against the outer wall of the T-shaped rail 102, thereby achieving the positioning of the slide block 103. The circuit board is clamped and fixed by means of two convex columns 105 moving closer to each other. The top of the slide block 103 is provided with a convex groove 104, and the convex column 105 is horizontally slidably connected to the inner side of the convex groove 104. The top of the slide block 103 and the outer side of the convex column 105 are provided with quick release components 3, which are used to realize the horizontal movement of the convex column 105, so as to release the clamping of the cable board when the slide block 103 is fixed.

[0033] Quick-release assembly 3 includes a limiting guide unit and a quick-movement unit;

[0034] The guide unit provides movement guidance and limitation for the convex column 105;

[0035] The quick-traverse unit is used to move and self-lock the convex column 105, and to perform clamping operations on circuit boards of the same type.

[0036] The limiting and guiding unit includes a fixed sealing plate 301, a guide post 302, and a second spring 303;

[0037] The fixing plate 301 is fixed to one end of the slide block 103 by bolts and extends out to the top of the slide block 103. The fixing plate 301 blocks the opening of the convex slide groove 104.

[0038] The guide post 302 is fixed to one end of the convex column 105 and passes through the fixed sealing plate 301. The guide post 302 and the fixed sealing plate 301 are slidably connected and are used to provide guidance for the movement of the convex column 105.

[0039] The second spring 303 is sleeved on the outside of the guide post 302 and distributed between the fixed sealing plate 301 and the convex post 105. The second spring 303 is used to provide elastic force for the reset of the convex post 105.

[0040] The quick-traverse unit includes a fixed shaft 304, a gear 305, a limit block 306, an L-shaped rotating arm 307, and a toothed plate 309.

[0041] The toothed plate 309 is fixed to the top of the slide block 103 and distributed on one side of the convex column 105.

[0042] The fixed shaft 304 is fixed to one side of the outer wall of the convex column 105, and the gear 305 is rotatably connected to the outside of the fixed shaft 304. The gear 305 meshes with the toothed plate 309.

[0043] Two limit blocks 306 are provided, and the two limit blocks 306 are fixed in a fan shape on the side of the gear 305 away from the convex column 105;

[0044] The L-shaped rotating arm 307 is rotatably connected to the outside of the fixed shaft 304 and fits against the side of the gear 305 away from the convex column 105. The L-shaped rotating arm 307 is in an inclined state and is distributed in the middle of the two limiting blocks 306. The bottom locking head of the L-shaped rotating arm 307 is engaged with the inner side of a tooth groove of the tooth plate 309 to realize the relative locking of the gear 305 and the tooth plate 309.

[0045] The L-shaped rotating arm 307 is rotated downwards to release the engagement with the toothed plate 309, while providing rotational power for the gear 305. The rotation of the gear 305 is used to realize the movement operation of the convex column 105.

[0046] A torsion spring 308 is also provided on the outside of the fixed shaft 304. The two ends of the torsion spring 308 are respectively engaged and fixed with the L-shaped rotating arm 307 and the fixed shaft 304. The torsion spring 308 provides a restoring elastic force for the L-shaped rotating arm 307.

[0047] In this embodiment: Under normal conditions, the bottom locking head of the L-shaped rotating arm 307 engages with a tooth groove of the toothed plate 309. At this time, the convex column 105 and the slide 103 are in a stable locked state. By loosening the first locking bolt 106, the slide 103 and the convex column 105 can be moved horizontally as a whole. In this way, the two clamping components 2 can be moved closer or further apart, thereby clamping or releasing circuit boards of different widths.

[0048] When performing batch soldering operations on circuit boards of the same model, the clamping of the circuit boards can be released using quick-release assembly 3, as follows:

[0049] When clamping the first circuit board, the two clamping components 2 are brought closer together by moving the slide block 103 to clamp the first circuit board.

[0050] After the soldering operation of the first circuit board is completed, when it is necessary to remove the first circuit board, the top of the L-shaped rotating arm 307 is pressed downward manually, causing the L-shaped rotating arm 307 to rotate around the fixed shaft 304. The bottom clamp of the L-shaped rotating arm 307 separates from the toothed plate 309 (the torsion spring 308 is further deformed and twisted). At the same time, the L-shaped rotating arm 307 rotates downward and contacts the lower limiting block 306. Then, the L-shaped rotating arm 307 continues to rotate downward. At this time, the L-shaped rotating arm 307 applies a deflection force to the gear 305 through the lower limiting block 306, causing the gear 305 to rotate. Under the limiting action of the toothed plate 309 on the gear 304, the rotating gear 305 moves horizontally, which in turn drives the convex column 105 and the clamping assembly 2 to move backward as a whole (during this process, the backward movement of the convex column 105 further compresses and deforms the second spring 303), thereby releasing the clamp on the first circuit board, so that the first circuit board can be easily removed.

[0051] Next, place the second circuit board (of the same model) between the two clamping components 2 and align it with the fixed clamping component 2. Then, slowly release the pressure on the L-shaped rotating arm 307. At this time, the convex column 105 and the clamping component 2 as a whole reset under the elastic force of the second spring 303, thus clamping the second circuit board. After the convex column 105 has reset, release the pressure on the L-shaped rotating arm 307. The L-shaped rotating arm 307 will reset to its initial state under the torque of the torsion spring 308. The bottom latch of the L-shaped rotating arm 307 will engage with the toothed plate 309 again, thus reinforcing the position of the convex column 105. (It should be noted that at this time, the L-shaped rotating arm 307 is in contact with the upper limit block 306, and the torsion spring 308 still exerts a pushing force on the L-shaped rotating arm 307.)

[0052] Please refer to this carefully. Figures 1-4 The clamping assembly 2 includes a side-tilted T-shaped post 201, a clamping block 202, a first spring 203, and a second locking bolt 204;

[0053] The side-inverted T-shaped column 201 extends from one end of the convex column 105 to the other end and is fixedly connected to the clamping block 202. The side-inverted T-shaped column 201 and the convex column 105 are rotatably connected.

[0054] The first spring 203 is distributed between the clamping block 202 and the convex column 105 and is sleeved on the outside of the side-inverted T-shaped column 201. The first spring 203 is used to provide rotational resistance for the clamping block 202.

[0055] The second locking bolt 204 is threaded onto one side of the convex column 105 and passes through the convex column 105, fitting tightly against the outer wall of the side-inverted T-shaped column 201. The second locking bolt 204 is used to provide rotational locking for the side-inverted T-shaped column 201.

[0056] In this embodiment, it should be noted that the clamping block 202 has slots at its port for inserting the edge of the circuit board. The slots are provided with multiple slots of different thicknesses to accommodate circuit boards of different thicknesses.

[0057] When clamping the circuit board, first adjust the two sets of clamping components 2 to be further apart so that their width is greater than that of the circuit board. Then, insert one edge of the circuit board into the slot of a clamping block 202. Then, move the other set of clamping components 2 closer to the circuit board. Finally, the other clamping block 202 engages with the other edge of the circuit board, thereby achieving the clamping of the circuit board.

[0058] By loosening the second locking bolt 204, the clamping block 202 and the side-inverted convex column 201 can be rotated as a whole, thereby realizing the angle adjustment of the circuit board and the flipping operation. The first spring 203 is used to provide frictional resistance between the clamping block 202 and the convex column 105, that is, with the second locking bolt 204 loosened, the clamping block 202 and the side-inverted convex column 201 can maintain a stable state when no external force is applied.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
