Description

Technical Field

[0001] The present invention relates to the technical field of welding, and particularly to a welding device for the production of cold storage refrigeration temperature controllers. Background Art

[0002] As the core control component of the cold storage refrigeration system, the performance of the cold storage refrigeration temperature controller directly affects the refrigeration effect and operation stability of the cold storage. During the production process of the cold storage refrigeration temperature controller, the welding of the circuit board and electronic components is one of the key links, and the welding quality plays a decisive role in the overall performance of the temperature controller.

[0003] When the existing equipment fixes the circuit board and electronic components, it usually adopts a relatively simple fixing method. Due to the lack of an effective fixing structure between the circuit board and electronic components before welding, it is difficult to ensure the accuracy of the relative position between the circuit board and electronic components. This easily leads to misalignment between the pins of the electronic components and the pads of the circuit board, resulting in welding defects such as virtual soldering and short circuits. Once these welding defects occur, the performance of the temperature controller will be severely affected, and even the temperature controller may not work properly. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the existing technology, the present invention provides a welding device for the production of cold storage refrigeration temperature controllers, which solves the problem that misalignment easily occurs between the pins of the electronic components and the pads of the circuit board in the existing equipment, resulting in welding defects such as virtual soldering and short circuits.

[0006] (II) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A welding device for the production of cold storage refrigeration temperature controllers includes a workbench, and electric soldering irons fixedly installed on both sides of the workbench. A support frame is fixedly connected to the top of the workbench, soldering iron holders are fixedly connected to both sides of the support frame, a flipping device is slidably connected to the top of the support frame, and a pressing device is slidably connected to the top of the flipping device;

[0008] The flipping device is used to fix the circuit board and flip the circuit board over. The flipping device includes a sliding block. A connecting rod is rotatably connected to the inner side of the sliding block. Knobs are rotatably connected to both ends of the connecting rod. Flipping frames are symmetrically and fixedly connected to the outer wall of the connecting rod. A fixing component is slidably connected to the inner wall of the flipping frame. The circuit board is clamped and fixed by the fixing component of the flipping device. Then, electronic components are placed so that the pins pass through the holes in the circuit board. Then, the pressing device presses the components onto the surface of the circuit board, so that the relative positions between the components and the circuit board are accurately locked. After that, the flipping device drives the circuit board, the electronic components and the pressing device to flip over as a whole, so that the component pins face upward. Finally, soldering is performed with a soldering iron. In this way, welding defects such as false soldering and short circuit caused by pin misalignment can be avoided, thereby improving the welding quality and the performance of the thermostat;

[0009] The fixing component includes a fixing block. A guiding rod is fixedly connected to the outer wall of the fixing block. A tension spring is fixedly connected to the outer side of the guiding rod. A connecting frame is fixedly connected to the side of the fixing block away from the guiding rod. A sliding plate is slidably connected to the outer wall of the connecting frame. A limiting strip is fixedly connected to the outer side of the sliding plate. Clamping blocks are rotatably connected to both sides of the connecting frame. By setting the guiding rod, the position of the fixing block relative to the flipping frame can change according to the overall width of the circuit board. When circuit boards of different widths are placed, the fixing block can adjust its position accordingly. Together with the tension spring, the limiting strip and the clamping blocks clamp the circuit board;

[0010] The pressing device is used to press the electronic components onto the circuit board fixed by the flipping device. The pressing device includes an adjusting frame. A limiting slider is slidably connected to the top of the adjusting frame. A fixing cylinder is fixedly connected to the inner side of the limiting slider. An adjusting component is slidably connected to the inner side of the fixing cylinder. Slide the position of the adjusting frame on the connecting rod so that it is in the same straight line as the electronic component. At this time, rotate the adjusting frame and fix it to the locking plate with a bolt. Then, adjust the position of the limiting slider so that it is directly above the electronic component, ensuring that the electronic component is evenly and stably pressed onto the surface of the circuit board.

[0011] Preferably, the soldering iron holder is used to place the soldering iron. Blocks are fixedly connected to the four sides of the top of the support platform frame. The blocks are used to assist in supporting the flipping device. The soldering iron holders on both sides of the support platform frame are used to place the soldering iron, which is convenient for the operator to pick up and ensures the stable placement of the soldering iron when not in use.

[0012] Preferably, the bottom of the sliding block is slidably connected to the inner walls on both sides of the support platform frame. A locking plate is fixedly connected to the side of the flipping frame away from the connecting rod. The outer wall of the connecting rod is slidably connected to the inner side of the pressing device. Rotate the knob so that the knob drives the flipping frame to flip 180 degrees through the connecting rod. Then, slide the sliding block so that the flipped flipping frame just rests on the surface of the block on the other side.

[0013] Preferably, the outer wall of the guide rod is slidably connected to the inner wall of the flipping frame. The outer wall of the flipping frame is fixedly connected to the outer side of the tension spring. A compression spring is fixedly connected to the side of the sliding plate away from the limiting strip. The end of the compression spring away from the sliding plate is fixedly connected to the inner side of the fixed block. Insert the circuit board between the two fixing components on both sides. At this time, the circuit board slides in the chute opened on the surface of the limiting strip, and forces the sliding plate to slide along the surface of the connecting frame, thereby compressing the compression spring. At this time, under the elastic force of the compression springs in the two fixing components on both sides, the two limiting strips can clamp the edges on both sides of the circuit board.

[0014] Preferably, limiting shafts are rotatably connected to both sides of the sliding plate. The outer wall of the limiting shaft is slidably connected to the inner wall of the clamping block through a sliding hole, and the sliding hole is opened in the wall of the clamping block. When the sliding plate slides along the surface of the connecting frame, at this time, the limiting shaft slides in the sliding hole along with the movement of the sliding plate, forcing the clamping blocks on both sides to deflect, thereby clamping the upper and lower surfaces of the circuit board and further fixing the circuit board in the vertical direction.

[0015] Preferably, one side of the adjusting frame is slidably connected to the outer wall of the connecting rod. The other side of the adjusting frame is fixedly connected to the inner wall of the locking plate through a bolt. An insertion block is fixedly connected to the outer side of the fixed cylinder. If the position of the limiting slider deviates, the pressure may act on the electronic component obliquely, resulting in poor contact between the electronic component and the circuit board, affecting the welding quality and electrical performance; Subsequently, the adjusting component can be used to press the electronic component tightly on the surface of the circuit board.

[0016] Preferably, the adjusting component includes a guide post. A ring-shaped slider is slidably connected to the outer wall of the guide post. A rotating ring is rotatably connected to the outer side of the ring-shaped slider. A compression spring is fixedly connected to the bottom of the ring-shaped slider. The bottom of the guide post is fixedly connected to a pressing block. Under the elastic force of the compression spring, the guide post can maintain a downward movement trend along the fixed cylinder, forcing the pressing block to press on the surface of the electronic component. The stable pressing force can expel the air and impurities between the pins and the pads, increasing the contact area between them.

[0017] Preferably, the outer wall of the guide post is slidably connected to the inner wall of the fixed cylinder. The inner wall of the fixed cylinder is slidably connected to the outer wall of the ring-shaped slider. The inner wall of the fixed cylinder is clamped with the outer wall of the rotating ring through a card slot, and the card slot is opened in the wall of the fixed cylinder. Slide the rotating ring out of the card slot, and the position of the ring-shaped slider in the fixed cylinder can be adjusted up and down, so that it can slide into other card slots, thereby changing the magnitude of the pressing force exerted by the pressing block on the surface of the electronic component.

[0018] Preferably, a latch is slidably connected to the outer side of the rotating ring, and the bottom of the latch is inserted into the inner side of the insertion block. When the latch is inserted into the insertion block, the rotating ring can be locked in one of the card slots. At this time, the position of the annular slider relative to the fixed cylinder is fixed. When the latch is pulled out of the insertion block, the rotating ring can rotate relative to the annular slider.

[0019] (III) Beneficial effects

[0020] The present invention provides a welding device for the production of cold storage refrigeration temperature controllers. It has the following beneficial effects:

[0021] (I) By setting a flipping device, the fixing component of the flipping device clamps and fixes the circuit board. Then, electronic components are placed so that the pins pass through the holes in the circuit board, and then the components are pressed against the surface of the circuit board by a pressing device, so that the relative positions between the components and the circuit board are accurately locked. After that, the flipping device drives the circuit board, the electronic components and the pressing device to turn over as a whole, making the component pins face upward. Finally, soldering is carried out with a soldering iron. In this way, welding defects such as virtual soldering and short circuit caused by pin misalignment can be avoided, thereby improving the welding quality and the performance of the temperature controller.

[0022] (II) By setting fixing components, the circuit board is inserted between the two fixing components on both sides. At this time, the circuit board slides in the sliding grooves opened on the surface of the limiting strips, and forces the sliding plate to slide along the surface of the connecting frame, thereby making the compression spring be compressed. At this time, under the elastic force of the compression springs in the two fixing components on both sides, the two limiting strips can clamp the edges on both sides of the circuit board to prevent the circuit board from shaking during welding.

[0023] (III) By setting clamping blocks, when the sliding plate slides along the surface of the connecting frame, the limiting shaft slides in the sliding holes as the sliding plate moves, forcing the clamping blocks on both sides to deflect, so as to clamp the upper and lower surfaces of the circuit board, further fixing the circuit board in the vertical direction, so as to adapt to circuit boards of different thicknesses, forming a multi-directional constraint on the circuit board and enhancing the stability of the circuit board fixation.

[0024] (IV) By setting guide rods, the position of the fixed block relative to the flipping frame can vary according to the overall width of the circuit board. When circuit boards of different widths are placed, the fixed block can adjust its position accordingly, and together with the tension spring, the limiting strips and the clamping blocks clamp the circuit board, so as to adapt to circuit boards of different sizes.

[0025] (5) By setting a pressing device, after the pins of the electronic component pass through the holes in the circuit board, the position of the sliding adjustment frame on the connecting rod is adjusted so that it is in the same straight line as the electronic component. At this time, the adjustment frame is rotated and fixed to the locking plate by bolts. Subsequently, the position of the limit slider is adjusted so that it is directly above the electronic component, ensuring that the electronic component is evenly and stably pressed on the surface of the circuit board; subsequently, the adjustment component can be used to press the electronic component on the surface of the circuit board.

[0026] (6) By setting an adjustment component, when the plug pin is inserted into the plug block, the rotating ring can be locked in one of the card slots. At this time, the position of the annular slider relative to the fixed cylinder is fixed. Under the elastic force of the pressing spring, the guide post can maintain a downward movement trend along the fixed cylinder, forcing the pressing block to press on the surface of the electronic component. The stable pressing force can expel the air and impurities between the pins and the pads, increase the contact area between them, thereby improving the reliability of welding and reducing the occurrence of welding defects such as virtual soldering and false soldering.

[0027] (7) By setting a card slot, when the plug pin is pulled out of the plug block, the rotating ring can rotate relative to the annular slider at this time, and the rotating ring is slid out of the card slot, so that the position of the annular slider in the fixed cylinder can be adjusted up and down, and it can slide into other card slots. Thus, the magnitude of the pressing force exerted by the pressing block on the surface of the electronic component can be changed, preventing it from damaging the electronic component, and at the same time, it can effectively press electronic components of different heights, ensuring the compatibility and applicability of the device to electronic components of various specifications.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment: Please refer to Figure 1-9 , the present invention provides a technical solution: A welding device for the production of a cold storage refrigeration temperature controller includes a workbench 1 and soldering irons 2 fixedly installed on both sides of the workbench 1.

A flipping device 5 is slidably connected to the top of the support stand 3. A pressing device 6 is slidably connected to the top of the flipping device 5; the soldering iron holders 4 are used to place the soldering irons 2. Cushion blocks 7 are fixedly connected to the four sides of the top of the support stand 3. The cushion blocks 7 are used to assist in supporting the flipping device 5. The workbench 1 serves as the basic support structure of the device, providing a stable platform for the entire welding operation. The soldering irons 2 fixedly installed on both sides are used for soldering the pins of electronic components and are the key tools for realizing welding. The soldering iron holders 4 on both sides of the support stand 3 are used to place the soldering irons 2, facilitating the operator to access and ensuring the stable placement of the soldering irons 2 when not in use.

[0040] The flipping device 5 is used to fix the circuit board and flip the circuit board over. The flipping device 5 includes a sliding block 51. A connecting rod 52 is rotatably connected to the inner side of the sliding block 51. Knobs 54 are rotatably connected to both ends of the connecting rod 52. Flipping frames 53 are symmetrically and fixedly connected to the outer wall of the connecting rod 52. A fixing component 56 is slidably connected to the inner wall of the flipping frame 53. The bottom of the sliding block 51 is slidably connected to the inner walls on both sides of the support platform frame 3. A locking plate 55 is fixedly connected to the side of the flipping frame 53 away from the connecting rod 52. The outer wall of the connecting rod 52 is slidably connected to the inner side of the pressing device 6. First, the circuit board is clamped and fixed by the fixing component 56 of the flipping device 5. Then, electronic components are placed so that the pins pass through the holes in the circuit board. Next, the components are pressed onto the surface of the circuit board by the pressing device 6, so that the relative positions between the components and the circuit board are accurately locked. After that, the knob 54 is rotated, so that the knob 54 drives the flipping frame 53 to flip 180 degrees through the connecting rod 52. Subsequently, the sliding block 51 is slid, so that the flipped flipping frame 53 just rests on the surface of the spacer 7 on the other side. At this time, the flipping device 5 drives the circuit board, the electronic components and the pressing device 6 to be turned over as a whole, so that the component pins face upward. Finally, soldering is performed with the soldering iron 2. In this way, welding defects such as false soldering and short circuit caused by pin misalignment can be avoided, thereby improving the welding quality and the performance of the thermostat.

[0041] The fixing member 56 includes a fixing block 561. The outer wall of the fixing block 561 is fixedly connected with a guide rod 562. The outer side of the guide rod 562 is fixedly connected with a tension spring 563. One side of the fixing block 561 away from the guide rod 562 is fixedly connected with a connecting frame 564. The outer wall of the connecting frame 564 is slidably connected with a sliding plate 567. The outer side of the sliding plate 567 is fixedly connected with a limiting strip 568. Both sides of the connecting frame 564 are rotatably connected with clamping blocks 566. The outer wall of the guide rod 562 is slidably connected with the inner wall of the flipping frame 53. The outer wall of the flipping frame 53 is fixedly connected with the outer side of the tension spring 563. One side of the sliding plate 567 away from the limiting strip 568 is fixedly connected with a compression spring 565. One end of the compression spring 565 away from the sliding plate 567 is fixedly connected with the inner side of the fixing block 561. Both sides of the sliding plate 567 are rotatably connected with limiting shafts 560. The outer walls of the limiting shafts 560 are slidably connected with the inner walls of the clamping blocks 566 through sliding holes 568, and the sliding holes 568 are formed in the walls of the clamping blocks 566. When fixing the circuit board, first insert the circuit board between the two fixing members 56 on both sides. At this time, the circuit board slides in the chute formed on the surface of the limiting strip 568, and forces the sliding plate 567 to slide along the surface of the connecting frame 564, thereby compressing the compression spring 565. At this time, under the elastic force of the compression springs 565 in the two fixing members 56 on both sides, the two limiting strips 568 can clamp the edges on both sides of the circuit board to prevent the circuit board from shaking during welding. When the sliding plate 567 slides along the surface of the connecting frame 564, at this time, the limiting shafts 560 slide in the sliding holes 569 along with the movement of the sliding plate 567, forcing the clamping blocks 566 on both sides to deflect, thereby clamping the upper and lower surfaces of the circuit board, further fixing the circuit board in the vertical direction to facilitate adapting to circuit boards of different thicknesses, forming a multi-directional constraint on the circuit board and enhancing the stability of the circuit board fixing. By setting the guide rod 562, the position of the fixing block 561 relative to the flipping frame 53 can vary according to the overall width of the circuit board. When placing circuit boards of different widths, the fixing block 561 can adjust its position accordingly, and then cooperate with the tension spring 563 to make the limiting strip 568 and the clamping block 566 jointly clamp the circuit board, so as to adapt to circuit boards of different sizes.

[0042] The pressing device 6 is used to press the electronic component onto the circuit board fixed by the flipping device 5. The pressing device 6 includes an adjusting frame 61. A limit slider 62 is slidably connected to the top of the adjusting frame 61. A fixed cylinder 63 is fixedly connected to the inner side of the limit slider 62. An adjusting component 65 is slidably connected to the inner side of the fixed cylinder 63. One side of the adjusting frame 61 is slidably connected to the outer wall of the connecting rod 52. The other side of the adjusting frame 61 is fixedly connected to the inner wall of the locking plate 55 by bolts. An insertion block 66 is fixedly connected to the outer side of the fixed cylinder 63. After passing the pins of the electronic component through the circuit board holes, slide the position of the adjusting frame 61 on the connecting rod 52 to make it in the same straight line as the electronic component. At this time, rotate the adjusting frame 61 and fix it to the locking plate 55 by bolts. Subsequently, adjust the position of the limit slider 62 to make it directly above the electronic component to ensure that the electronic component is evenly and stably pressed on the surface of the circuit board. If the position of the limit slider 62 deviates, the pressure may act on the electronic component obliquely, resulting in poor contact between the electronic component and the circuit board, affecting the welding quality and electrical performance. Subsequently, the adjusting component 65 can be used to press the electronic component onto the surface of the circuit board.

[0043] The adjusting component 65 includes a guiding column 651. An annular slider 652 is slidably connected to the outer wall of the guiding column 651. A rotating ring 653 is rotatably connected to the outer side of the annular slider 652. A pressing spring 655 is fixedly connected to the bottom of the annular slider 652. A pressing block 656 is fixedly connected to the bottom of the guiding column 651. The outer wall of the guiding column 651 is slidably connected to the inner wall of the fixed cylinder 63. The inner wall of the fixed cylinder 63 is slidably connected to the outer wall of the annular slider 652. The inner wall of the fixed cylinder 63 is clamped with the outer wall of the rotating ring 653 through a card slot 64, and the card slot 64 is opened in the wall of the fixed cylinder 63. A plug pin 654 is slidably connected to the outer side of the rotating ring 653. The bottom of the plug pin 654 is inserted into the inner side of the insertion block 66. When the plug pin 654 is inserted into the insertion block 66, the rotating ring 653 can be locked in one of the card slots 64. At this time, the position of the annular slider 652 relative to the fixed cylinder 63 is fixed. Under the elastic force of the pressing spring 655, the guiding column 651 can maintain a downward movement trend along the fixed cylinder 63, forcing the pressing block 656 to press on the surface of the electronic component. The stable pressing force can exclude the air and impurities between the pins and the pads, increase the contact area between them, thereby improving the reliability of welding and reducing the occurrence of welding defects such as false soldering and cold soldering. When the plug pin 654 is pulled out from the insertion block 66, at this time, the rotating ring 653 can rotate relative to the annular slider 652. Slide the rotating ring 653 out of the card slot 64, and the position of the annular slider 652 in the fixed cylinder 63 can be adjusted up and down so that it can slide into other card slots 64. Thus, the pressing force of the pressing block 656 acting on the surface of the electronic component can be changed to prevent it from damaging the electronic component. At the same time, it can also effectively press electronic components of different heights, ensuring the compatibility and applicability of the device to various specifications of electronic components.

[0044] Working principle:

[0045] During use, the workbench 1 serves as the basic support structure of the device, providing a stable platform for the entire welding operation. The soldering irons 2 fixedly installed on both sides are used for soldering the pins of electronic components and are the key tools for achieving welding. The iron holders 4 on both sides of the support frame 3 are used to place the soldering irons 2, facilitating the operator to pick them up and ensuring the stable placement of the soldering irons 2 when not in use;

[0046] First, the fixing part 56 of the flipping device 5 clamps and fixes the circuit board. Then, the electronic components are placed so that the pins pass through the holes in the circuit board. Next, the pressing device 6 presses the components tightly on the surface of the circuit board to accurately lock the relative positions between the components and the circuit board. After that, the knob 54 is rotated, and the knob 54 drives the flipping frame 53 to flip 180 degrees through the connecting rod 52. Subsequently, the sliding block 51 is slid, so that the flipped flipping frame 53 just rests on the surface of the cushion block 7 on the other side. At this time, the flipping device 5 drives the circuit board, the electronic components and the pressing device 6 to turn over as a whole, making the component pins face upward. Finally, the soldering iron 2 is used for soldering, thereby avoiding welding defects such as false soldering and short circuit caused by pin misalignment, and thus improving the welding quality and the performance of the thermostat;

[0047] When fixing the circuit board, first insert the circuit board between the fixing parts 56 on both sides. At this time, the circuit board slides in the chute opened on the surface of the limiting strip 568, and forces the sliding plate 567 to slide along the surface of the connecting frame 564, thereby causing the compression spring 565 to be compressed. At this time, under the elastic force of the compression spring 565 in the two fixing parts 56 on both sides, the two limiting strips 568 can clamp the edges on both sides of the circuit board to prevent the circuit board from shaking during welding;

[0048] When the sliding plate 567 slides along the surface of the connecting frame 564, at this time, the limiting shaft 560 slides in the sliding hole 569 along with the movement of the sliding plate 567, forcing the clamping blocks 566 on both sides to deflect, thereby clamping the upper and lower surfaces of the circuit board, further fixing the circuit board in the vertical direction to facilitate adapting to circuit boards of different thicknesses, forming a multi-directional constraint on the circuit board and enhancing the stability of the circuit board fixation.

[0049] By setting the guide rod 562, the position of the fixing block 561 relative to the flipping frame 53 can vary according to the overall width of the circuit board. When placing circuit boards of different widths, the fixing block 561 can adjust its position accordingly, and together with the tension spring 563, the limiting strip 568 and the clamping block 566 clamp the circuit board together, so as to adapt to circuit boards of different sizes;

[0050] After passing the pins of the electronic component through the holes in the circuit board, slide the adjusting bracket 61 to the position on the connecting rod 52 so that it is in a straight line with the electronic component. At this time, rotate the adjusting bracket 61 and fix it to the locking plate 55 with bolts. Subsequently, adjust the position of the limit slider 62 so that it is directly above the electronic component, ensuring that the electronic component is evenly and stably pressed against the surface of the circuit board. If the position of the limit slider 62 deviates, the pressure may act on the electronic component obliquely, resulting in poor contact between the electronic component and the circuit board and affecting the welding quality and electrical performance. Subsequently, the adjusting component 65 can be used to press the electronic component against the surface of the circuit board.

[0051] When the bolt 654 is inserted into the socket 66, the rotating ring 653 can be locked in one of the card slots 64. At this time, the position of the annular slider 652 relative to the fixed cylinder 63 is fixed. Under the elastic force of the pressing spring 655, the guide post 651 can maintain a downward movement trend along the fixed cylinder 63, forcing the pressing block 656 to press on the surface of the electronic component. The stable pressing force can expel the air and impurities between the pins and the pads, increase the contact area between them, thereby improving the reliability of welding and reducing the occurrence of welding defects such as false soldering and cold soldering.

[0052] When the bolt 654 is pulled out of the socket 66, at this time, the rotating ring 653 can rotate relative to the annular slider 652, and the rotating ring 653 can be slid out of the card slot 64, so that the position of the annular slider 652 in the fixed cylinder 63 can be adjusted up and down, and it can slide into other card slots 64. Thus, the magnitude of the pressing force exerted by the pressing block 656 on the surface of the electronic component can be changed, preventing it from damaging the electronic component. At the same time, it can also effectively press electronic components of different heights, ensuring the compatibility and applicability of the equipment to various specifications of electronic components.
