[0002] Currently, selective wave soldering commonly uses chains to transport PCBs. The PCBs need to be positioned at the soldering location. Due to the limitations of the chain, the PCBs are often too high above the solder pot nozzle in actual production, making them prone to soldering defects. An innovative design has been developed to replace the chain-type transport with a roller-type transport, rendering the original pusher structure unsuitable. In the prior art, Chinese patent CN201751072U discloses a pusher device for selective wave soldering. This pusher device is fixed to the outside of roller A on the wave soldering equipment and includes a slide rail component fixed to the wave soldering equipment. The slide rail component serves as a guide mechanism for a pusher rod used to clamp the PCB, achieving precise guidance and positioning. An automated power component compatible with the wave soldering control system is used for automated control of the pusher rod. However, this pusher device only adjusts in one direction, resulting in low adjustment accuracy. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please see Figures 1 to 5 This invention provides a selective wave soldering machine for adjusting and fixing a workpiece 3. The selective wave soldering machine includes a connecting frame 1 and a fixing device 2. The fixing device 2 is mounted on the connecting frame 1, and the workpiece 3 is fixedly connected to the fixing device 2. In use, adjusting the fixing device 2 allows for fine-tuning and fixing of the workpiece 3.

[0025] The fixing device 2 includes a push plate 21, a limiting block 22, and a rhombus plate 23. The push plate 21 is fixedly connected to the fixed workpiece 3 and can slide relative to the connecting frame 1 in a first direction. The limiting block 22 is fixedly connected to the push plate 21 and can slide on the connecting frame 1 in a second direction. The rhombus plate 23 is fixedly connected to the limiting block 22 and can slide relative to the connecting frame 1 in a third direction.

[0026] The rhomboid plate 23 includes a main body 231 and a guide 232 connected to each other. The guide 232 is located at the bottom of the main body 231. The main body 231 is fixedly connected to the limiting block 22, and the guide 232 is slidably connected to the connecting frame 1.

[0027] The fixing device 2 further includes a first adjusting member 24, a second adjusting member 25, and a third adjusting member 26. The first adjusting member 24 is used to adjust the push plate 21 back and forth along a first direction; the second adjusting member 25 is used to adjust the limiting block 22 left and right along a second direction; and the third adjusting member 26 is used to adjust the rhomboid plate 23 up and down along a third direction. In this embodiment, using... Figure 1For example, the first direction is the Z-axis direction, the second direction is the X-axis direction, and the third direction is the Y-axis direction.

[0028] Furthermore, one end of the first adjusting member 24 passes through the connecting frame 1 and abuts against the push plate 21, and the first adjusting member 24 is threadedly connected to the connecting frame 1. Specifically, the connecting frame 1 has a threaded hole 10, and the first adjusting member 24 is threadedly connected to the threaded hole 10. When it is necessary to make a fine adjustment to the push plate 21, the first adjusting member 24 is rotated, thereby allowing the first adjusting member 24 to slide relative to the connecting frame 1, and thus push the push plate 21 to slide back and forth in the first direction. In this embodiment, the first adjusting member 24 is a bolt. In other embodiments not shown, the second adjusting member 24 can also be a pin or a shaft.

[0029] The second adjusting member 25 includes a sliding member 251 and a locking member 252. One end of the sliding member 251 is provided with a limiting block 22 and the locking member 252, and the sliding member 251 and the locking member 252 are threadedly connected. The locking member 252 is slidably mounted on the connecting frame 1. When it is necessary to fine-tune the limiting block 22, the sliding member 251 is loosened, so that the second adjusting member 25 can slide relative to the connecting frame 1, and the limiting block 22 can slide left and right in the second direction.

[0030] In this embodiment, the sliding member 251 is a bolt, and the locking member 252 is a nut. In other embodiments not shown, the second adjusting member 24 may also be a pin or a shaft.

[0031] Furthermore, the connecting frame 1 has a first slide groove 11, which is located on the side wall of the connecting frame 1, and the locking member 252 is slidably disposed in the first slide groove 11. In use, the locking member 252 can slide left and right along the extending direction of the first slide groove 11.

[0032] To prevent the locking member 252 from disengaging from the first slide groove 11, the first slide groove 11 includes a sliding part 111 and a through part 112 that are interconnected. The width of the sliding part 111 is greater than the width of the through part 112. The cross-section of the sliding part 111 is approximately triangular. The locking member 252 includes a locking part 2521 and a connecting part 2522 that are interconnected. The locking part 2521 is slidably disposed in the sliding part 111, and the connecting part 2522 is slidably disposed in the through part 112.

[0033] When it is necessary to fix the limiting block 22, rotate the sliding member 251 so that the sliding member 251 moves closer to the locking member 252 until the sliding member 251 abuts against the connecting frame 1, thereby fixing the sliding member 251 and fixing the limiting block 22.

[0034] The third adjusting component 26 includes a bolt 261 and a nut 262. One end of the bolt 261 passes through the rhombus plate 23 and the nut 262, and the bolt 261 is threadedly connected to the rhombus plate 23 and the nut 262. The connecting frame 1 has a second sliding groove 12, which is located on the upper end surface of the connecting frame 1. The nut 262 is slidably disposed in the second sliding groove 12. In use, the nut 262 can slide left and right along the extension direction of the second sliding groove 12. Specifically, the rhombus plate 23 has a through hole 233, and one end of the bolt 261 passes through the through hole 233 and is threadedly connected to the nut 262. In use, rotating the third adjusting component 26 can drive the rhombus plate 23, the limiting block 22, and the push plate 21 to make slight up and down adjustments, thereby enabling the fixed workpiece 3 to make slight up and down adjustments.

[0035] Furthermore, the limiting block 22 is provided with a waist-shaped groove 221, and one end of the sliding member 251 is provided through the waist-shaped groove 221 and the locking member 252. Since one end of the sliding member 251 extends into the first sliding groove 11, when the limiting block 22 is adjusted up and down, the sliding member 251 slides up and down in the waist-shaped groove 221 along the extension direction of the waist-shaped groove 221.

[0036] Furthermore, the limiting block 22 and the push plate 21 are fixedly connected by a fixing member 220, one end of which passes through the limiting block 22 and is fixedly connected to the push plate 21. Specifically, the upper end face of the limiting block 22 is recessed to form an adjustment groove 222, which extends through the upper and lower end faces of the limiting block 22. When the first adjusting member 24 pushes against the push plate 21, the fixing member 220 slides back and forth in the adjustment groove 222 along the extension direction of the adjustment groove 222.

[0037] The fixing device or selective wave soldering provided by this utility model has a high adjustment accuracy by setting a push plate 21, a limiting block 22 and a rhombus block 23, with the limiting block 22 slidably set on the connecting frame 1 along the second direction, the push plate 21 slidably relative to the connecting frame 1 along the first direction, and the rhombus block 23 slidably relative to the connecting frame 1 along the third direction.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
