Description

Technical Field

[0001] This utility model relates to the field of PCB circuit board processing, and in particular to a general-purpose fixture for wave soldering. Background Technology

[0002] Wave soldering is a critical process in the production of PCB circuit boards. It involves using a power pump to create solder waves of a specific shape on the surface of a solder bath by molten liquid solder. When the PCB circuit board passes through the wave at a specific angle, the components are soldered. During wave soldering, fixtures are used to fix the PCB circuit board to ensure the stability and accuracy of the soldering.

[0003] In the existing technology, the fixtures used for wave soldering of PCB circuit boards usually clamp the PCB circuit boards by means of a single clamping plate. This method has obvious shortcomings. When it is necessary to clamp PCB boards of different lengths, the clamping plates need to be locked one by one, which is cumbersome and inefficient. The same applies to disassembly, which increases the labor intensity of the workers.

[0004] Therefore, it is necessary to invent a universal fixture for passing through wave peaks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a universal fixture for passing through wave peaks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a universal fixture for wave cresting, comprising a rectangular frame plate, a rectangular placement groove at the top of the central opening of the rectangular frame plate, two movable plates slidably disposed within the rectangular frame plate, each movable plate having a strip-shaped placement groove on its opposite side, a single-sided limiting component at the top of both the rectangular frame plate and the movable plates, the single-sided limiting component including a fixed plate, a first threaded hole at the top of both the rectangular frame plate and the movable plates, a first bolt threaded into the first threaded hole, a first strip-shaped opening corresponding to the first bolt on the surface of the fixed plate, multiple clamping plates slidably disposed on the top of the fixed plate, multiple sliding grooves corresponding to the clamping plates at the top of the fixed plate, a second threaded hole at the sliding groove, a second bolt threaded into the second threaded hole, a second strip-shaped opening corresponding to the second bolt on both the upper and lower sides of the clamping plate, and an adjustment component disposed on the movable plate.

[0007] Preferably, the adjusting assembly includes a horizontal locking strip, which is connected to the top of the movable plate by bolts. A first stud is threadedly connected to the top of the horizontal locking strip, and a pressure plate is slidably disposed on the outer side of the first stud. A first nut is threadedly connected to the outer wall of the first stud. Two vertical locking strips are provided on the top of the rectangular frame plate, which are connected to the top of the rectangular frame plate by bolts. A U-shaped adjusting plate is slidably disposed inside the vertical locking strip, and a second stud is threadedly connected to the top of the U-shaped adjusting plate. The top end of the second stud passes through the pressure plate and is threadedly connected to a second nut.

[0008] Preferably, the two opposing single-sided limiting components together form a double-sided limiting component.

[0009] Preferably, the middle area between the rectangular placement slot and the strip placement slot is the placement opening.

[0010] Preferably, a pull block is fixedly connected to the top of the clamping plate.

[0011] The technical effects and advantages of this utility model are as follows: By setting a fixing plate and locking the fixing plate with the first bolt, multiple clamping plates are all on the fixing plate. Adjusting the position of one fixing plate can adjust the position of multiple clamping plates, which simplifies the operation steps and improves work efficiency. At the same time, since multiple clamping plates can be adjusted freely, different numbers of clamping plates can be used to clamp the PCB circuit board according to its length, which is more flexible and can adapt to PCB boards of different lengths.

[0014] 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.

[0015] This utility model provides, for example Figure 1-6 The diagram shows a general-purpose fixture for wave cresting, comprising a rectangular frame plate 1. A rectangular placement groove 2 is formed at the top of the central opening of the rectangular frame plate 1. Two movable plates 3 are slidably disposed within the rectangular frame plate 1. Each movable plate 3 has a strip-shaped placement groove 4 on its opposite side. A single-sided limiting component 5 is provided at the top of both the rectangular frame plate 1 and the movable plates 3. The single-sided limiting component 5 includes a fixed plate 51. A first threaded hole is formed at the top of both the rectangular frame plate 1 and the movable plates 3, and a first bolt 52 is threaded into the first threaded hole. A first strip-shaped opening 53 corresponding to the first bolt 52 is formed on the surface of the fixed plate 51. Multiple clamping plates 54 are slidably disposed at the top of the fixed plate 51. Multiple sliding grooves 55 corresponding to the clamping plates 54 are formed at the top of the fixed plate 51. The sliding grooves 55 have openings... The device is provided with a second threaded hole, and a second bolt 56 is threaded into the second threaded hole. The upper and lower sides of the clamping plate 54 are provided with second slots 57 corresponding to the second bolts 56. The movable plate 3 is provided with an adjustment component 6. Multiple clamping plates 54 are located on the fixed plate 51, which is locked by the first bolt 52. If the PCB circuit board is long, the position of multiple clamping plates 54 can be adjusted by adjusting the position of one fixed plate 51, thereby clamping the long PCB circuit board. Since multiple clamping plates 54 can be freely adjusted, if the PCB circuit board is short, different numbers of clamping plates 54 can be used to clamp the PCB circuit board according to its length.

[0016] The adjusting assembly 6 includes a horizontal locking strip 61, which is bolted to the top of the movable plate 3. A first stud 62 is threaded to the top of the horizontal locking strip 61. A pressure plate 63 is slidably disposed on the outer side of the first stud 62, and a first nut 64 is threaded to the outer wall of the first stud 62. Two vertical locking strips 65 are provided on the top of the rectangular frame plate 1, and are bolted to the top of the rectangular frame plate 1. A U-shaped adjusting plate 66 is slidably disposed inside the vertical locking strips 65, and a second stud 67 is threaded to the top of the U-shaped adjusting plate 66. The top of the second stud 67 passes through the pressure plate 63 and is threaded to a second nut 68. The horizontal locking strip 61... The vertical locking strip 65 is connected to the horizontal locking strip 61 by a pressure plate 63 and a first nut 64. After adjusting the position of the moving plate 3, the second nut 68 is tightened, pressing the pressure plate 63 against the vertical locking strip 65. This fixes the position of the moving plate 3. To adjust the position of the moving plate 3, the second nut 68 is rotated in the opposite direction, so that the pressure plate 63 is not pressed against the vertical locking strip 65. Then, the moving plate 3 is pulled, allowing the U-shaped adjusting plate 66 to slide within the vertical locking strip 65, thus adjusting the position of the moving plate 3.

[0017] The two opposing single-sided limiting components 5 together form a double-sided limiting component. By using the two sets of single-sided limiting components 5 to clamp the upper and lower edges of the PCB circuit board, the stability of the PCB circuit board wave soldering can be maintained.

[0018] The middle area between the rectangular placement slot 2 and the strip placement slot 4 is the placement opening 7. The PCB circuit board can be placed by placing it in the placement opening 7 and placing it on the rectangular placement slot 2 and the strip placement slot 4.

[0019] A pull block 8 is fixedly connected to the top of the clamping plate 54. By pulling the pull block 8, one of the clamping plates 54 can be pulled individually.

[0020] The working principle of this utility model is as follows: Adjust the distance between the two movable plates 3 according to the width of the PCB circuit board. Rotate the second nut 68 in the opposite direction so that the pressure plate 63 is not pressed against the vertical clamping strip 65. Pull the movable plate 3, and the U-shaped adjusting plate 66 slides within the vertical clamping strip 65. When the movable plate 3 is adjusted to the appropriate position, lock the second nut 68 so that the pressure plate 63 is pressed against the vertical clamping strip 65, thus fixing the movable plate 3. Place the PCB circuit board into the placement opening 7. If the PCB circuit board is long, loosen the first bolt 52 and move the fixed plate 51. Since multiple clamping plates 54 are all set on the fixed plate 51, they will move the multiple clamping plates. 54 are moved together and adjusted to a suitable position. Then, the first bolt 52 is tightened to fix the fixing plate 51. The clamping plate 54 extends out of the rectangular placement slot 2 and the strip placement slot 4 to clamp the PCB circuit board on the rectangular placement slot 2 and the strip placement slot 4. If the PCB circuit board is short, the corresponding number of clamping plates 54 can be pulled in the slide groove 55 by the pull block 8 according to its length. After adjusting the position, the second bolt 56 is tightened. The clamping plate 54 is fixed by the cooperation of the second bolt 56 and the second strip opening 57. The upper and lower sides of the PCB circuit board are clamped by the double-sided limiting component composed of two opposite single-sided limiting components 5.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
