Technical Field
[0001] This utility model relates to the field of welding technology, and in particular to a welding device for circuit board production. Background Technology
[0002] Welding is a mechanical process used to permanently join two or more metallic or non-metallic materials by heating, pressurizing, or a combination of both. Its core components include power supply systems, welding systems, clamping and positioning equipment, etc.
[0003] In the field of welding, existing technologies often require the use of clamps to fix the circuit boards to be welded in order to ensure welding accuracy. However, when welding circuit boards of different sizes and widths, existing circuit board welding methods require constant replacement of clamps, which greatly reduces welding efficiency and increases labor costs.

This utility model employs a welding device for circuit board production, including a base plate. A fixing plate is fixedly connected to the top of the base plate. A moving mechanism is provided at the front end of the fixing plate, and a clamping mechanism is provided at the top of the base plate. The moving mechanism includes a fixed frame, the rear end of which is fixedly connected to the front end of the fixing plate. A one-way threaded rod is rotatably connected inside the fixed frame, and a threaded block is threadedly connected to the outer wall of the one-way threaded rod. An electric push rod is fixedly connected to the front end of the threaded block. In this utility model, the moving mechanism can drive the soldering iron tip to move horizontally and rise and fall, thus facilitating the soldering of circuit boards of different sizes and models. This eliminates the need for manual movement by workers, reducing their workload and improving work efficiency.
[0005] The following defects were found in response to the above: In the field of welding, in the existing technology, when welding circuit boards, it is often necessary to use a fixture to fix the circuit board to be welded in order to ensure the welding accuracy. However, when the existing circuit board welding faces circuit boards of different sizes and widths, it is necessary to constantly change the fixture for fixation, which greatly reduces the welding efficiency and increases labor costs. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing circuit board welding methods, which require constant changes of fixtures for fixing circuit boards of different sizes and widths, greatly reducing welding efficiency and increasing labor costs. Therefore, this invention proposes a welding device for circuit board production.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a welding device for circuit board production, comprising a base, a support column, and a welding machine. A fixing device is provided on the upper surface of the base. The fixing device includes a base plate, which is fixedly connected to the base. Sliding grooves are provided on both sides of the base plate. Sliding plates are slidably connected to the inner walls of the two sliding grooves. Two rectangular grooves are provided on the upper surface of the sliding plates. Sliding blocks are slidably connected to the inner walls of the two rectangular grooves. A support plate is fixedly connected to the upper surface of the sliding blocks. A screw is rotatably connected to the upper surface of the support plate. A limiting rod is fixedly connected to the upper surface of the support plate. A pressure plate is slidably connected to the arc surface of the limiting rod. The pressure plate is threadedly connected to the screw. Two cylinders are fixedly connected to the upper surface of the sliding plates. A processing table is fixedly connected to the upper surfaces of the two cylinders.
[0008] The effect achieved by the above components is as follows: when it is necessary to solder the circuit board, the circuit board is placed on the processing table, and the screw is turned so that the pressure plate moves downward, thereby pressing and fixing the circuit board to be soldered.
[0009] Preferably, a rubber strip is fixedly connected to the lower surface of both pressure plates, and the rubber strip is rectangular.
[0010] The effect achieved by the above components is that when the rubber strip comes into contact with the circuit board, the rubber strip can increase the friction between the two, resulting in a better fixing effect.
[0011] Preferably, a limiting plate is fixedly connected to one side of the two rectangular grooves that are far apart from each other, and a round rod is fixedly connected to one side of each of the two limiting plates. The round rod is slidably connected to the slider and fixedly connected to the rectangular groove.
[0012] The effect achieved by the above components is that the limiting plate restricts the direction of the slider's movement, preventing the slider from slipping out of the rectangular groove.
[0013] Preferably, a spring is fitted onto the arc surface of the round rod, and the spring is fixedly connected to the slider and the limiting plate respectively.
[0014] The effect achieved by the above components is as follows: when the spring is in an uncompressed state, the two pressure plates are above the processing table. The pressure plates need to be pushed away from each other to place the circuit board. After placement, the pressure plates are released, and the spring pushes the pressure plates back to their original position due to the elastic force. This facilitates the operation of the processing personnel and speeds up the processing efficiency.
[0015] Preferably, a storage device is provided on one side of the base. The storage device includes a storage slot, which is opened on one side of the base. A rectangular hole is opened on the side of the base away from the support column. Two slide rails are fixedly connected to the inner wall of the storage slot. A rectangular strip is slidably connected to the inner wall of each of the two slide rails. An outer frame is fixedly connected to the side of the two rectangular strips that are close to each other. A rectangular plate is fixedly connected to one side of the outer frame.
[0016] The effect achieved by the above components is that after the circuit board is soldered, the circuit board can be placed in the outer frame. After storing a certain number of circuit boards, the rectangular plate can be pulled out of the outer frame to transport the processed circuit boards to the designated location in one go.
[0017] Preferably, a handle is fixedly connected to one side of the rectangular plate, and the handle has a "U" shaped cross-section.
[0018] The effect achieved by the above components is that the outer frame can be pulled out by using the handle to pull the rectangular plate, which is more convenient and less strenuous.
[0019] Preferably, a plurality of foam strips are fixedly connected to the upper surface of the outer frame, and the plurality of foam strips are evenly distributed on the surface of the outer frame.
[0020] The effect achieved by the above components is that when placing the circuit board, several foam strips can act as a buffer to prevent damage to the circuit board.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting a fixing device, when welding circuit boards, the pressure plate needs to be manually pushed away from each other. Since the pressure plate is fixedly connected to the limiting rod, and the limiting rod is also fixedly connected to the support plate, and the support plate is fixedly connected to the slider, pushing the pressure plate will cause the support plate to move towards the limiting plate. The slider is slidably connected to the rectangular groove, so pushing the pressure plate will also cause the slider to slide along the rectangular groove towards the limiting plate. The limiting plate restricts the slider's sliding direction, preventing it from slipping out of the rectangular groove. During the slider's movement, since the spring is fixedly connected to the slider and the limiting plate, and the spring is fitted onto the round rod, the slider compresses the spring as it moves towards the limiting plate, generating elastic force. When the circuit board to be welded is large enough to be placed on the processing table, the pressure plate is stopped from being pushed. Releasing the pressure plate at this point causes the slider to spring back to its original position due to the spring force, and the pressure plate returns to the top of the processing table. At this point, the screw can be turned. Since the screw and the pressure plate are connected by a thread, the pressure plate will move downwards when the screw is turned. At this time, the distance between the two sliders can also be finely adjusted so that the two pressure plates press onto the appropriate part of the circuit board to avoid hindering the welding process. After the welding process is completed, the slide plate can be pushed along the groove of the base plate to the side of the storage slot for easy storage.
[0023] In this invention, a storage device is provided. After welding is completed, the sliding plate can be pushed along the groove of the base plate to the side of the storage groove. At this time, the screw needs to be loosened to move the two pressure plates upward, thus releasing the circuit board. Then, the welded circuit board can be manually placed into the outer frame. When processing time is urgent, the circuit board can also be directly pushed from the processing table into the outer frame. The gaps between the several foam strips fixedly connected to the bottom of the outer frame are small enough to protect the circuit board and prevent it from being damaged. The outer frame can store a certain number of circuit boards. When there are no more circuit boards, the handle can be pulled away from the base. Since the handle is fixedly connected to the rectangular plate, and the rectangular plate is fixedly connected to the outer frame, pulling the handle will also pull the rectangular plate and the outer frame. Two rectangular strips are fixedly connected to both sides of the outer frame. The two rectangular strips are slidably connected to the two slide rails. So, while pulling, the outer frame will slide along the slide rail groove towards the rectangular hole until it slides out of the rectangular hole. Then, the processed circuit board can be placed in the designated area at once. The handle facilitates operation for processing personnel and saves manpower. Attached Figure Description

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a welding device for circuit board production, including a base 1, a support column 2, and a welding machine 3. A fixing device 4 is provided on the upper surface of the base 1, and a storage device 5 is provided on one side of the base 1.
[0030] The following section will explain the specific design and function of the fixing device 4 and the storage device 5.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the fixing device 4 includes a base plate 401, which is fixedly connected to the base 1. Both sides of the base plate 401 are provided with sliding grooves 402. The inner walls of the two sliding grooves 402 are slidably connected to sliding plates 403. The upper surface of the sliding plate 403 is provided with two rectangular grooves 404. The inner walls of the two rectangular grooves 404 are slidably connected to sliders 405. The upper surface of the sliders 405 is fixedly connected to a support plate 406. The upper surface of the support plate 406 is rotatably connected to a screw 407. The upper surface of the support plate 406 is fixedly connected to a limit rod 408. The arc surface of the limit rod 408 is slidably connected to a pressure plate 409. The pressure plate 409 is threadedly connected to the screw 407. The upper surface of the sliding plate 403 is fixedly connected to two cylinders 414. The upper surface of the two cylinders 414 is fixedly connected to a processing table 413. When soldering is required on a circuit board, the circuit board is placed on the processing table 413. Rotating the screw 407 moves the pressure plate 409 downwards, thereby pressing and fixing the circuit board to be soldered. Rubber strips 410, which are rectangular in shape, are fixedly connected to the lower surfaces of both pressure plates 409. When the rubber strips 410 contact the circuit board, they increase the friction between them, resulting in better fixing. Limiting plates 415 are fixedly connected to the opposite sides of the two rectangular grooves 404. A round rod 412 is fixedly connected to one side of each limiting plate 415. The round rod 412 is slidably connected to the slider 405 and fixedly connected to the rectangular groove 404. The limiting plates 415 restrict the sliding direction of the slider 405, preventing it from slipping out of the rectangular groove 404. A spring 411 is fitted onto the arc surface of the round rod 412, and the spring 411 is fixedly connected to both the slider 405 and the limiting plate 415. When the spring 411 is in an uncompressed state, the two pressure plates 409 are above the processing table 413. The pressure plates 409 need to be pushed away from each other to place the circuit board. After placement, the pressure plates 409 are released, and the spring 411 pushes the pressure plates 409 back to their original position due to the elastic force. This facilitates the operation of the processing personnel and speeds up the processing efficiency.
[0032] Reference Figure 4As shown in this embodiment: the storage device 5 includes a storage slot 51, which is located on one side of the base 1. A rectangular hole 52 is provided on the side of the base 1 away from the support column 2. Two slide rails 53 are fixedly connected to the inner wall of the storage slot 51. Rectangular strips 54 are slidably connected to the inner walls of the two slide rails 53. An outer frame 55 is fixedly connected to the side of the two rectangular strips 54 that are close to each other. A rectangular plate 56 is fixedly connected to one side of the outer frame 55. After the circuit board is soldered, the circuit board can be placed in the outer frame 55. After storing a certain number of circuit boards, the rectangular plate 56 is pulled to pull out the outer frame 55, transporting the processed circuit board to the designated location in one go. A handle 57 is fixedly connected to one side of the rectangular plate 56. The cross-section of the handle 57 is "U". Pulling the rectangular plate 56 with the handle 57 to pull out the outer frame 55 is more convenient and labor-saving. Several foam strips 58 are fixedly connected to the upper surface of the outer frame 55. The several foam strips 58 are evenly distributed on the surface of the outer frame 55. When placing the circuit board, several foam strips 58 can act as a buffer to prevent damage to the circuit board.
[0033] In this invention, by setting a fixing device 4, when soldering circuit boards is required, the pressure plate 409 needs to be manually pushed in a direction away from each other. Since the pressure plate 409 is fixedly connected to the limiting rod 408, and the limiting rod 408 is also fixedly connected to the support plate 406, and the support plate 406 is fixedly connected to the slider 405, when the pressure plate 409 is pushed, the pressure plate 409 will drive the support plate 406 to move towards the limiting plate 415. The slider 405 is slidably connected to the rectangular groove 404, so when the pressure plate 409 is pushed, the slider 405 will also slide along the rectangular groove 404 towards the limiting plate 415. The limiting plate 415 restricts the sliding direction of the slider 405 and prevents the slider 405 from slipping out of the rectangular groove 404. During the sliding process of slider 405, since spring 411 is fixedly connected to slider 405 and limiting plate 415, and spring 411 is sleeved on round rod 412, slider 405 will squeeze spring 411 while moving towards limiting plate 415, so that spring 411 generates elastic force. When the circuit board to be welded is large enough to be placed on processing table 413, the pressure plate 409 is stopped being pushed. At this time, the pressure plate 409 is released, and slider 405 will be driven by the elastic force of spring 411 to push pressure plate 409 back to its original position. Pressure plate 409 will return to the top of processing table 413. At this point, the screw 407 can be turned. Since the screw 407 and the pressure plate 409 are connected by a thread, the pressure plate 409 will move downwards when the screw 407 is turned. At this time, the distance between the two sliders 405 can also be finely adjusted so that the two pressure plates 409 press onto the appropriate part of the circuit board to avoid hindering the soldering process. After the soldering process is completed, the slide plate 403 can be pushed along the slide groove 402 of the base plate 401 to the side of the storage slot 51 for easy storage.
[0034] In this invention, by setting up a storage device 5, after the welding process is completed, the sliding plate 403 can be pushed to slide along the groove 402 of the base plate 401 to the side of the storage groove 51. At this time, the screw 407 needs to be loosened so that the two pressure plates 409 move upward to release the circuit board. Then, the welded circuit board can be manually placed into the outer frame 55. When the processing time is urgent, the circuit board can also be directly pushed from the processing table 413 into the outer frame 55. The gaps between the several foam strips 58 fixedly connected to the bottom of the outer frame 55 are small enough to protect the circuit board and prevent it from being damaged. The outer frame 55 can store a certain number of circuit boards. When processing the circuit board, the handle 57 can be pulled away from the base 1. Since the handle 57 is fixedly connected to the rectangular plate 56, and the rectangular plate 56 is fixedly connected to the outer frame 55, pulling the handle 57 will also pull the rectangular plate 56 and the outer frame 55. Two rectangular strips 54 are fixedly connected to both sides of the outer frame 55. The two rectangular strips 54 are slidably connected to the two slide rails 53. So when pulling, the outer frame 55 will slide along the groove of the slide rail 53 towards the rectangular hole 52 until it slides out of the rectangular hole 52. Then the processed circuit board can be placed in the designated area at once. The handle 57 facilitates the operation of the processing personnel and saves manpower.
