Description

Technical Field

[0001] The invention belongs to the technical field of electronic component welding, and in particular relates to a PCB board positioning welding device and a positioning welding method. Background Art

[0002] In the field of electronic equipment manufacturing, the assembly and connection technology of PCB boards is of vital importance. In the prior art, the assembly of PCB boards that need to be tightly connected and compact often faces the problems of complex operation, low positioning accuracy, and poor connection stability. In particular, in the scenario where small PCB boards are firmly connected through equidistant connecting pieces, traditional welding methods often require manual fixing of PCB boards, adjustment and welding one by one, which is inefficient and easy to damage the PCB boards. For PCB board operations that require welding of multiple equidistant connecting pieces, traditional methods are difficult to achieve the goal of high efficiency. Summary of the invention

[0003] The purpose of the present invention is to design a PCB board positioning welding device and a positioning welding method to address the shortcomings and deficiencies of traditional PCB board welding processes, so as to achieve efficient welding of PCB boards with multiple equidistant connecting pieces.

[0004] In order to achieve the above purpose / solve the above technical problems, the present invention is implemented by adopting the following technical solutions: In a first aspect, the present invention provides a PCB board positioning welding device, the PCB board positioning welding device comprising a PCB board positioning unit, which is used to fix the bottom PCB board and the vertical PCB board to be welded; The PCB board positioning unit comprises a base, a short slide, a PCB board limit block and a fixed limit block; The base plate is provided with a bottom plate fixing structure for fixing and connecting the bottom PCB board; The short slide is fixed at one end of the base, the fixed limit block is fixed at the other end of the base, and the short slide is provided with a short slide moving end capable of moving relative to the fixed limit block; The PCB board limiting block is fixedly connected to the movable end of the short slide, so as to be able to approach or move away from the fixed limiting block to clamp the vertical PCB board.

[0005] The effect produced by the above settings: PCB board positioning mainly fixes the PCB board placed on the bottom and the vertically placed PCB board through bolts and a short slide. The base fixes the bottom PCB board through the bottom plate fixing structure. Then, by operating the short slide, the PCB board limit block and the fixed limit block cooperate with each other to clamp the vertically arranged PCB board, so that the bottom PCB board to be welded and the vertical PCB board are fixed, and then further welding is carried out.

[0006] Furthermore, the device also includes a connecting piece welding unit, which is used to position the connecting piece between the bottom PCB board and the vertical PCB board to be welded.

[0008] The effect of the above settings: The connecting piece welding mainly positions and places the connecting pieces attached to the strong magnetic material through a long slide to realize array arrangement. The long slide drives the fixture to move, thereby driving the attached connecting pieces to move to the corresponding positions between the bottom PCB board to be welded and the vertical PCB board, preparing for the next step of welding.

[0009] Further, the clamp includes a strong magnetic clamp and a magnet; The magnet is fixedly connected to the connection block, and the strong magnetic clamp is adsorbed on the connection block through the magnet, and is used to adsorb the connection piece, so as to drive the attached connection piece to move with the movement of the moving end of the long slide.

[0010] The effect of the above settings is that the connection block can be fixed by magnet adsorption after lifting the clamp of strong magnetic material, and the connection piece can be pushed down when pressed down. The mechanical clamp needs to tighten the bolts to fix it, and the bolts need to be loosened when pressed down. It is more convenient to use magnets.

[0011] Furthermore, the base plate fixing structure includes bolt holes arranged on the base plate.

[0012] The above arrangement produces an effect of: connecting the bolt holes arranged on the base plate and the bolt holes on the bottom PCB board by bolts.

[0013] Furthermore, both the PCB board limiting block and the fixed limiting block are provided with limiting grooves adapted to the vertical PCB board.

[0014] The above settings produce the following effects: the limiting grooves are conducive to better clamping and positioning the vertical PCB board so that it fits above the bottom PCB board.

[0015] Furthermore, the strong magnetic clamp is provided with a slot for fixing the connecting piece.

[0016] The above settings produce the following effects: the card slots on the strong magnetic clamp are conducive to better fixing the connecting piece, and are convenient for fixing and positioning when the connecting piece is pressed down.

[0018] Furthermore, the device also includes a connecting piece welding unit, which is used to position the connecting piece between the bottom PCB board and the vertical PCB board to be welded.

[0019] The connecting piece welding unit comprises a long slide, a connecting block and a clamp; The long slide is arranged on the base, and a movable long slide moving end is arranged on the base; The connecting block is fixedly connected to the moving end of the long slide; the clamp is detachably connected to the connecting block and is used to install the connecting piece, so as to drive the attached connecting piece to move with the movement of the moving end of the long slide; The method further comprises: When the connecting piece welding unit is working, after the PCB board positioning work is completed, the connecting piece is placed in the card slot of the fixture, and the relative position of the fixture is adjusted by using the long slide. After reaching the specified position, the fixture is pressed down to make the connecting piece fit with the bottom PCB board and the vertical PCB board respectively, and the welding work begins; After the welding is completed, lift the fixture. At this time, the connecting piece has been welded to the fixed PCB board, and the connecting piece falls off; Another connecting piece is taken and placed in the card slot of the fixture, and the position of the fixture is adjusted again by the long slide to carry out the next round of welding of the connecting pieces until the welding work of the entire connecting piece array is completed.

[0020] Compared with the prior art, the present invention has the following advantages: The present invention limits the position of the PCB board by using a short slide table, so as to facilitate fixing and taking out.

Example 1

[0029] like Figure 1-4 As shown, this embodiment provides a PCB board positioning welding device, including a PCB board positioning unit, which is used to fix the bottom PCB board 10 and the vertical PCB board 10 to be welded; The PCB board positioning unit comprises a base 1, a short slide 9, a PCB board 10, a limit block 7 and a fixed limit block 3; The base plate is provided with a bottom plate fixing structure for fixing and connecting the bottom PCB board 10; The short slide 9 is fixed at one end of the base 1, the fixed limit block 3 is fixed at the other end of the base 1, and the short slide 9 is provided with a short slide 9 moving end capable of moving relative to the fixed limit block 3; The PCB board 10 limiting block 7 is fixedly connected to the movable end of the short slide 9 so as to be able to approach or move away from the fixed limiting block 3 to clamp the vertical PCB board 10 .

[0030] The PCB board positioning mainly fixes the PCB board 10 placed on the bottom surface and the PCB board 10 placed vertically through bolts and the short slide 9. The base 1 fixes the bottom PCB board 10 through the bottom plate fixing structure. Then, by operating the short slide 9, the PCB board 10 limit block 7 and the fixed limit block 3 cooperate with each other to clamp the vertically arranged PCB board 10 so that the bottom PCB board 10 to be welded and the vertical PCB board 10 are fixed, and then further welding is performed.

[0031] Specifically, the device further comprises a connecting piece 2 welding unit, and the connecting piece 2 welding unit is used to position the connecting piece 2 between the bottom PCB board 10 and the vertical PCB board 10 to be welded.

[0032] The connecting piece 2 welding unit comprises a long slide 8, a connecting block 6 and a clamp; The long slide 8 is arranged on the base 1, and a movable end of the long slide 8 is arranged on the base 1; The connecting block 6 is fixedly connected to the moving end of the long slide 8; the clamp is detachably connected to the connecting block 6 and is used to install the connecting piece 2, thereby driving the attached connecting piece 2 to move with the movement of the moving end of the long slide 8.

[0033] The welding of the connecting piece 2 mainly positions and places the connecting piece 2 attached to the strong magnetic material through the long slide 8 to realize the array arrangement. The long slide 8 drives the clamp to move, thereby driving the attached connecting piece 2 to move to the corresponding position between the bottom PCB board 10 to be welded and the vertical PCB board 10, so as to prepare for the next step of welding.

[0034] Specifically, the clamp includes a strong magnetic clamp 5 and a magnet 4; the magnet 4 is fixedly connected to the connecting block 6, and the strong magnetic clamp 5 is adsorbed on the connecting block 6 through the magnet 4, and is used to adsorb the connecting piece 2, thereby driving the attached connecting piece 2 to move with the movement of the moving end of the long slide 8. After the connecting block 6 lifts the clamp of the strong magnetic material, it can be adsorbed and fixed by the magnet 4, and the connecting piece 2 can be pushed down when pressed down. When using a mechanical clamp, it is also necessary to tighten the bolts to fix it, and the bolts need to be loosened when pressing down. It is more convenient to use the magnet 4.

[0035] Specifically, the bottom plate fixing structure includes bolt holes arranged on the base plate, and the bolt holes arranged on the base plate are connected with the bolt holes on the bottom PCB board 10 by bolts.

[0036] Specifically, the PCB board 10 limit block 7 and the fixed limit block 3 are both provided with limit grooves adapted to the vertical PCB board 10. The limit grooves are conducive to better clamping and positioning the vertical PCB board 10 so that it fits above the bottom PCB board 10.

[0037] Specifically, the strong magnetic clamp 5 is provided with a slot for fixing the connecting piece 2. The slot on the strong magnetic clamp 5 is conducive to better fixing the connecting piece 2, and is convenient for fixing and positioning when the connecting piece 2 is pressed down. Example 2

[0038] like Figure 1 As shown, this embodiment provides a PCB board positioning welding device, which is used in the technical field of electronic component welding. The technical solution involved mainly consists of two parts: a PCB board positioning unit and a connecting piece welding unit.

[0039] The PCB board positioning unit mainly fixes the PCB board 10 placed on the bottom surface and the PCB board 10 placed vertically through bolts and the short slide 9. The connecting piece welding unit mainly positions and places the connecting pieces 2 attached to the strong magnetic material through the long slide 8 to realize array arrangement.

[0040] The PCB board positioning unit is composed of a base 1, a short slide 9, a PCB board limit block 7, and a fixed limit block 3. The short slide 9 is fixed at one end of the base 1, the fixed limit block 3 is fixed to the edge of the other end of the base 1, and the PCB board limit block 7 is fixedly connected to the moving end of the short slide 9.

[0041] The short slide 9 is used to fix the PCB board limit block 7 with the moving end of the short slide 9 to clamp or release the PCB board 10.

[0042] The connecting piece 2 welding unit is composed of a long slide 8, a connecting block 6, a strong magnetic clamp 5, and a magnet 4. The upper end of the base 1 is fixedly connected to the long slide 8, the upper end of the movable end of the long slide 8 is fixedly connected to the connecting block 6, and the other end of the connecting block 6 is connected to the strong magnetic clamp 5, and the strong magnetic clamp 5 is adsorbed on the connecting block 6 through the magnet 4.

[0043] The long slide 8 is used to fix the connection block 6 with the moving end of the long slide 8. The strong magnetic clamp 5 is fixedly attached to the connection block 6 through the magnet 4. The movement of the slider of the long slide 8 drives the strong magnetic clamp 5 to move for easy welding.

[0044] There is a small slot under the strong magnetic material, which is where the connecting piece 2 is placed. Figure 1 (with connecting piece 2) Figure 3 (Without connecting piece 2), the circle on connecting piece 2 is a through hole, and this through hole is used to complete other work, which is not related to this application. After lifting the strong magnetic material, it can be adsorbed and fixed by magnet 4, and pushed down when pressing down. Using a mechanical clamp also requires tightening the bolts to fix it, and loosening the bolts when pressing down. It is more convenient to use magnet 4.

[0045] like Figure 2As shown, when the PCB board positioning welding unit is working, the short slide 9 is adjusted to the initial position, a bottom PCB board 10 is fixed to the base 1 by bolts, and the limiting grooves of the fixed limiting blocks 3 are used to accurately stack four additional PCB boards 10 on the main PCB board 10 on the base 1. By operating the short slide 9, the PCB board limiting blocks 7 and the fixed limiting blocks 3 cooperate with each other to firmly clamp the four PCB boards 10.

[0046] After the welding process is successfully completed, the short slide 9 is operated again to return to the starting position and the bolts of the main PCB board 10 are removed to take out the product.

[0047] like Figure 3 As shown, when the connecting piece 2 welding unit is working, a magnet 4 is embedded in the connecting block 6 to absorb the strong magnetic clamp 5. After the PCB board positioning work is completed, the connecting piece 2 is placed in the card slot of the strong magnetic clamp 5, and the long slide 8 is used to adjust the relative position of the strong magnetic clamp 5. After reaching the position, the strong magnetic clamp 5 is pressed down to make the connecting piece 2 fit the pad, and the welding work starts. After the welding is completed, the strong magnetic clamp 5 is lifted to carry out the next round of welding of the connecting piece 2 until the welding work of the entire connecting piece 2 array is completed.

[0048] Press the connecting piece 2 down to fit it with the pad position (left, right, and bottom).

[0049] The connection relationship between the connecting piece 2 and the bottom PCB board 10 and the vertical PCB board 10 is as follows: Figure 4 As shown, the soldering pad is the position with tin on the PCB board 10, that is, the place where the connecting piece 2 is connected to the PCB board 10. Figure 1 and Figure 4 Several small vertical strips can be observed, which are the solder pads.

[0050] Figure 4 In the figure, the two yellow through holes at the front of the bottom PCB board 10 are used to fix the PCB board 10 placed on the bottom surface. They can be fixed by connecting them with the threaded holes of the base plate through bolts.

[0051] The four vertical PCB boards 10 placed vertically are divided into two groups, and then there is Figure 4 Display array. Figure 4 The yellow positions all around are the installation positions of the connecting piece 2, which are installed in an array of yellow bars with equal spacing. Figure 4 In the figure, a set of connecting pieces 2 are installed on each side, but it is not limited to Figure 4 Configuration shown. Example 3

[0052] This embodiment provides a PCB board positioning welding method, based on the device described in Embodiment 1, comprising the following steps: When the PCB board positioning welding unit is working, the short slide 9 is adjusted to the initial position, a main PCB board 10 is fixed on the base 1 by bolts, and the limiting grooves of the fixed limiting blocks 3 are used to accurately stack four additional PCB boards 10 on the main PCB board 10 on the base 1 so that they are completely fitted with the main PCB board 10. By operating the short slide 9, the PCB board limiting blocks 7 and the fixed limiting blocks 3 cooperate with each other to firmly clamp the four PCB boards 10 and start welding.

[0053] After the welding process is successfully completed, the short slide 9 is operated again to return it to the starting position, and the bolts of the main PCB board 10 are removed to take out the product.

[0054] When the connecting piece 2 welding unit is working, a magnet 4 is embedded in the connecting block 6 to absorb the strong magnetic clamp 5. After the PCB board positioning work is completed, the connecting piece 2 is placed in the card slot of the strong magnetic clamp 5, and the long slide 8 is used to adjust the relative position of the strong magnetic clamp 5. After reaching the specified position, the strong magnetic clamp 5 is pressed down to make the connecting piece 2 fit the pad and start the welding work. After the welding is completed, the strong magnetic clamp 5 is lifted. Since the connecting piece 2 has been welded to the fixed PCB board 10, the connecting piece 2 falls off. At this time, take two more connecting pieces 2 and place them in the card slots of the strong magnetic clamp 5. The position of the strong magnetic clamp 5 is adjusted by the long slide 8 again, and the next round of welding of the connecting pieces 2 is carried out until the welding work of the entire connecting piece 2 array is completed.
