Description

A coil pin tinning device Technical Field

[0001] This application relates to the field of tinning equipment technology, and in particular to a coil pin tinning apparatus. Background Technology

[0002] Currently, with the rapid development and changes in science and technology, the requirements and trends for the size design of electronic consumables are getting smaller and smaller, and the requirements for the structure of cables and electronic wires are smaller and finer, thus the requirements for the processing of electronic wires are getting higher and higher.

[0003] After the coil is assembled, the exposed wire leads of the coil need to be tinned. Tinning is an essential part of the manufacturing process of electronic products, especially timers. Traditionally, tinning is done manually. The usual practice is for a person to hold the coil and immerse the exposed wire leads into the tinning container, so that the coil leads are immersed in the solder liquid to complete the tinning operation. Due to the instability of manual tinning, it is difficult for the worker to maintain a consistent tinning depth, resulting in low tinning quality. Therefore, more and more manufacturers are producing or purchasing tinning equipment to replace manual tinning, so that the tinning depth is consistent and the processing quality is improved. However, when using current tinning equipment, the worker needs to place the coils one by one onto the tinning main component. Only after the coils are placed can the tinning main component be moved to move the coils to the tinning container for tinning. This makes the tinning efficiency low and difficult to meet the continuous processing needs of mass production. Summary of the Invention

[0004] To improve the tinning efficiency of coil pins, this application provides a coil pin tinning apparatus.

[0005] This application provides a coil pin tinning device, which adopts the following technical solution:

[0006] A coil pin tinning device includes a machine base. The top of the machine base is provided with a top frame and a tinning box. A transverse sliding seat is slidably connected to the side wall of the top frame. A lifting assembly is provided on the side wall of the transverse sliding seat.

The coil is picked up by the coil picking device, and then the transverse seat is moved to the top of the tinning box. The tinning box is lowered by the lifting component, so that the lead wire of the coil is immersed in the tinning box for tinning. At the same time as tinning, the coil can be placed on the coil fixing rod. After tinning is completed, the coil can be removed from the coil picking device, and the transverse seat can be moved again to pick up the coil, shortening the tinning time interval and improving tinning efficiency.

[0015] By adopting the above technical solution, after the tinning is completed, the coil take-up piece can be moved into the inlet / outlet tank, so that the coil is located between the stripper and the clamping plate. The coil take-up piece is moved upward, and the clamping plate blocks the coil, causing the coil to separate from the coil take-up piece, thereby quickly removing the coil for the next round of tinning and improving the tinning efficiency.

[0036] The present application will be further described in detail below with reference to Figures 1-4.

[0037] This application discloses a coil pin tinning device.

[0038] Referring to Figure 1, a coil pin tinning device includes a machine base 1. A top frame 11 and a tinning box 12 are provided on the top side of the machine base 1. The tinning box 12 is located in the middle of the top side of the machine base 1 and contains solder liquid. A transverse support 2 is slidably connected to the side wall of the top frame 11. A transverse drive 21, which is a rodless cylinder, is provided on the side wall of the top frame 11. The drive end of the transverse drive 21 is connected to the transverse support 2. A lifting assembly is provided on the side wall of the transverse support 2. A tinning seat 3 is connected to the side wall of the lifting assembly. The lifting assembly includes a lifting seat 22 and a lifting drive 23, which is a cylinder. The lifting seat 22 is slidably connected to the side wall of the horizontal moving seat 2 and is installed on the side wall of the horizontal moving seat 2. The lifting seat 22 slides vertically and is installed at the output end of the lifting drive component 23. The tin-dipping seat 3 is connected to the side wall of the lifting seat 22. The tin-dipping seat 3 is provided with a coil grabbing component 31 for grabbing coils. The top of the machine base 1 is provided with a coil loading frame 13. The coil loading frame 13 is located in the moving path of the horizontal moving seat 2. Several coil fixing rods 14 are provided on the side of the coil loading frame 13 near the top frame 11. The coil fixing rods 14 are arranged horizontally and the arrangement direction of the coil fixing rods 14 is perpendicular to the sliding direction of the horizontal moving seat 2.

[0039] When large-volume tinning is required, the coil can be placed on the coil fixing rod 14, so that the coil fixing rod 14 clamps the coil. The horizontal moving drive 21 drives the horizontal moving seat 2 to move horizontally closer to the coil loading frame 13. The coil is picked up by the coil picking member 31. Then, the horizontal moving seat 2 is moved to directly above the tinning box 12, and the lifting drive 23 drives the lifting seat 22 to descend, so that the lead wire of the coil is immersed in the tinning box 12 for tinning. At the same time as tinning, the coil can be placed on the coil fixing rod 14. After tinning is completed, the coil on the coil picking member 31 can be removed, and the horizontal moving seat 2 can be moved again to pick up the coil. It is not necessary to put the coil into the coil picking member 31 one by one before tinning, thereby shortening the waiting time for putting in the coil and improving the tinning efficiency.

[0040] Referring to Figures 2 and 3, the soldering base 3 extends horizontally. A plurality of limiting rings 32 are provided on the side of the soldering base 3 near the ring-taking member 31. The limiting rings 32 are arranged along the extending direction of the soldering base 3. The ring-taking member 31 is located within the limiting rings 32. The number of ring-taking members 31 within the same limiting ring 32 is at least two. In this embodiment, the number of ring-taking members 31 within the same limiting ring 32 is two. The ring-taking member 31 is arranged in a semi-frustum shape, and the arcuate portion of the ring-taking member 31 abuts against the inner wall of the limiting ring 32. Next, the end face area of ​​the ring taker 31 away from the immersion solder base 3 is larger than the end face area of ​​the ring taker 31 close to the immersion solder base 3. The ring takers 31 are symmetrically arranged, and an elastic member 33 is provided between adjacent ring takers 31. The elastic member 33 is a spring. The two ends of the elastic member 33 are respectively connected to the side walls of the ring takers 31 that are close to each other within the same limiting ring 32. The side walls of the ring takers 31 that are close to each other are provided with grooves, and the end of the elastic member 33 is fixed to the side wall of the groove.

[0041] When tinning is required, the coil is mounted on the coil loading rack 13, and the tinning base 3 is moved closer to the coil loading rack 13, causing the coil take-up piece 31 to be inserted into the coil. The elastic member 33 applies a pushing force to the coil take-up piece 31, causing the coil take-up pieces 31 to move away from each other and press against the inner wall of the coil, thereby grasping the coil. At this time, the tinning base 3 is moved away from the coil loading rack 13, and the coil can be removed from the coil loading rack 13 for tinning. There is no need to wait for the staff to place the coils one by one on the coil take-up piece 31, which shortens the coil placement time and improves tinning efficiency.

[0042] The immersion soldering base 3 has an internal cavity 34. A through hole is formed on the side of the immersion soldering base 3 near the limiting ring 32, and the through hole communicates with the cavity 34. The limiting ring 32 encloses the end of the through hole away from the cavity 34. A sliding frame 35 is slidably connected inside the cavity 34, and the sliding frame 35 slides and engages with the side wall of the cavity 34. The extending direction of the sliding frame 35 is consistent with the extending direction of the immersion soldering base 3, and the sliding direction of the sliding frame 35 is perpendicular to the extending direction of the immersion soldering base 3. The end of the take-up ring 31 near the immersion soldering base 3 passes through the through hole into the cavity 34, and the take-up ring 31 slides with the sliding frame 35. The connection is made so that the end of the ring 31 that passes through the cavity 34 is provided with a slider 36. The slider 36 is a T-shaped block. The slider 36 is slidably connected to the side of the sliding frame 35 near the limiting ring 32. The sliding direction of the slider 36 is perpendicular to the sliding direction of the transverse seat 2. The cavity 34 is provided with a lifting drive 37 for driving the sliding frame 35 to move. The lifting drive 37 is a cylinder. The driving end of the lifting drive 37 is connected to the sliding frame 35. The inner wall of the limiting ring 32 is provided in the shape of a frustum hole. The inner diameter of the limiting ring 32 near the immersion solder seat 3 is smaller than the inner diameter of the limiting ring 32 away from the immersion solder seat 3.

[0043] When it is necessary to remove the coil from the coil loading rack 13, the tinning seat 3 is driven to move closer to the coil loading rack 13, so that the coil take-up piece 31 is inserted into the coil. Then, the extension drive 37 drives the sliding frame 35 to move closer to the limiting ring 32. The elastic member 33 applies a pushing force to the coil take-up piece 31, so that the coil take-up pieces 31 move away from each other, thereby making the coil take-up piece 31 press against the opposite sides of the inner wall of the coil. Then, the tinning seat 3 can be driven to move away from the coil loading rack 13, so that the coil on the coil loading rack 13 can be removed at once. It is simple and quick. Since the coil take-up piece 31 is in the shape of a semi-circular frustum, after the coil take-up piece 31 is inserted into the coil, the coil take-up piece 31 that opens to each other can limit the coil. This can reduce the situation where the coil falls off the coil take-up piece 31 during the movement and needs to be removed and repositioned, thus improving the tinning efficiency.

[0044] Referring to Figure 1, the immersion soldering base 3 is rotatably connected to the side wall of the lifting base 22. The rotation axis of the immersion soldering base 3 extends in the horizontal direction. The side wall of the lifting base 22 is equipped with a flipping drive 24 for driving the immersion soldering base 3 to rotate. The flipping drive 24 is a servo motor, and the drive end of the flipping drive 24 is connected to the immersion soldering base 3.

[0045] The immersion holder 3 can be moved between the coil loading rack 13 and the immersion box 12. After the coil is removed from the coil loading rack 13 by the coil take-up member 31, the flipping drive member 24 drives the immersion holder 3 to rotate, so that the immersion holder 3 is located between the coil loading rack 13 and the coil take-up member 31. The transverse slide 2 is then moved to place the coil take-up member 31 above the immersion box 12. The lifting seat 22 can then be lowered, so that the coil on the coil take-up member 31 is close to the immersion box 12 for immersion. The rotation of the immersion holder 3 and the movement of the transverse slide 2 can be carried out simultaneously, thereby shortening the time to move the coil above the immersion box 12 and improving the immersion efficiency.

[0046] Referring to Figures 1 and 4, the top side of the machine base 1 is provided with a stripping seat 4 and a clamping plate 41. The tin-immersion box 12 is located between the coil loading frame 13 and the stripping seat 4. The clamping plate 41 is located above the stripping seat 4. Both the stripping seat 4 and the clamping plate 41 extend in the horizontal direction. The clamping plate 41 has an inlet / outlet slot 42 for inserting the coil 31 on the side near the tin-immersion box 12.

[0047] After the coil is immersed in tin, the lifting seat 22 is driven to rise, and the transverse seat 2 is driven to move, so that the coil take-up piece 31 moves to the side of the clamping plate 41 near the tin-immersion box 12, and inserts the coil take-up piece 31 into the inlet / outlet slot 42. At the same time, the coil is positioned between the clamping plate 41 and the stripper seat 4. At this time, the sliding frame 35 is driven to move away from the limiting ring 32, and the coil take-up piece 31 moves towards the cavity 34. Since the coil take-up piece 31 abuts against the inner wall of the limiting ring 32, the coil take-up pieces 31 move closer to each other under the limiting action of the limiting ring 32. The coil take-up piece 31 moves away from the inner wall of the coil, and the lifting seat 22 is driven to rise. The coil is separated from the coil take-up piece 31 under the obstruction of the clamping plate 41, and the coil falls onto the stripper seat 4, thus completing the collection of the coil after tin immersion. This allows for the next round of tin immersion processing without the need for workers to remove the coil take-up piece 31 one by one. The coil is removed at once, which speeds up the stripping speed and facilitates the next round of tin immersion, thereby improving the tin immersion efficiency.

[0048] The stripping seat 4 is slidably connected to the top side of the machine base 1. The sliding direction of the stripping seat 4 is consistent with the sliding direction of the stripping seat 4. The top side of the machine base 1 is provided with a stripping drive 43 for driving the stripping seat 4 to slide. The stripping drive 43 is a cylinder. The drive end of the stripping drive 43 is connected to the bottom of the stripping seat 4. The top side of the stripping seat 4 is rotatably connected with a feeding plate 44. The extension direction of the feeding plate 44 is consistent with the extension direction of the stripping seat 4. The extension direction of the rotation axis of the feeding plate 44 is consistent with the extension direction of the feeding plate 44. The stripping seat 4 is provided with a feeding drive 45 for driving the feeding plate 44 to rotate. The feeding drive 45 is a servo motor. The drive end of the feeding drive 45 is connected to the feeding plate 44.

[0049] When the coil separates from the coil-retrieving component 31, it falls onto the top side of the feeding plate 44. At this time, the unloading drive component 43 can be made to drive the unloading seat 4 to move horizontally, so that the unloading seat 4 and the feeding plate 44 are away from the bottom of the clamping plate 41. Then, the unloading drive component 45 can be made to drive the feeding plate 44 to rotate upward, so that the coil can be poured out of the feeding plate 44, thereby collecting the coil and unloading quickly, leaving space on the top side of the feeding plate 44.

[0050] Referring to Figure 1, a solder scraper 5 is slidably connected to the side wall of the solder immersion box 12. The side wall of the solder immersion box 12 is provided with a solder scraper drive 51 for driving the solder scraper 5 to move. The solder scraper drive 51 is a servo motor. The output end of the solder scraper drive 51 is connected to a lead screw 52. The extension direction of the lead screw 52 is perpendicular to the sliding direction of the transverse seat 2. The solder scraper 5 is threadedly engaged with the lead screw 52. The sliding direction of the solder scraper 5 is consistent with the extension direction of the lead screw 52.

[0051] After the coil is immersed in tin, impurities from the coil may remain in the tin immersion box 12, affecting the subsequent tin immersion effect. Therefore, after tin immersion, the tin scraper drive 51 can drive the lead screw 52 to rotate, causing the tin scraper 5 to move along the extension direction of the lead screw 52. The tin scraper 5 scrapes away the impurities and tin dross on the tin immersion box 12, thereby reducing the impact on subsequent tin immersion and ensuring the tin immersion quality.

[0052] A slidable squeegee 53 is slidably connected to the side wall of the immersion tin box 12. The sliding direction of the squeegee 53 is consistent with the extension direction of the lead screw 52. The squeegee 53 is threadedly connected to the lead screw 52, ​​and the lead screw 52 passes through the squeegee 53. The squeegee 5 is slidably connected to the squeegee 53. The squeegee 5 is located at the top of the squeegee 53. The squeegee 5 slides vertically on the squeegee 53. The squeegee 5 is provided with a lifting and lowering drive 54 for driving the squeegee 5 to move. The lifting and lowering drive 54 is a cylinder. The driving end of the lifting and lowering drive 54 is connected to the squeegee 5. The end of the squeegee 5 near the immersion tin box 12 is arranged in the shape of a scraper.

[0053] After the tin scraper 5 removes the impurities and solder dross from the tin-dipping tray 12, the solder liquid level in the tin-dipping tray 12 drops. At this time, the tin scraper 5 can be raised and lowered by the lifting drive 54 to adjust the height of the tin scraper 5 to a suitable position for scraping, thereby reducing the loss of solder liquid and saving costs.

[0054] The top of the machine base 1 is equipped with a controller 6, and the lifting drive component 23 is electrically connected to the controller 6. Two transmission rods 61 are fixed on the side wall of the tin-immersion base 3. The transmission rods 61 are made of metal and are electrically connected to the controller 6.

[0055] Before tinning, the tinning base 3 can be rotated so that the guide rod 61 faces the top of the tinning box 12, driving the lifting base 22 and the tinning base 3 to descend, bringing the guide rod 61 close to the solder liquid in the tinning box 12. The solder liquid is a molten metal. When the guide rod 61 contacts the solder liquid, the guide rod 61 is energized and transmits an electrical signal to the controller 6. After receiving the signal, the controller 6 stops the lifting drive 23 from driving the lifting base 22 to descend, marks the descent height of the lifting base 22, and then drives the lifting base 22 and the tinning base 3 to rise. The tinning base 3 is rotated so that the coil pins on the coil take-up piece 31 face the top of the tinning box 12. The lifting base 22 and the tinning base 3 are driven to descend according to the marked descent height to perform tinning. This method can accurately control the descent height of each tinning operation, reducing the possibility of poor tinning quality due to insufficient descent height, and also reducing the possibility of excessive descent height causing the pins to enter the tinning box 12 too deeply, resulting in wasted solder liquid.

[0056] The lifting drive unit 54 is electrically connected to the controller 6, and the solder scraper 5 is made of metal and is electrically connected to the controller 6.

[0057] During the descent of the lifting drive 54 and the solder scraper 5, when the solder scraper 5 comes into contact with the solder liquid, the solder scraper 5 transmits an electrical signal to the controller 6, causing the lifting drive 54 to stop driving. Then, the solder scraper drive 51 can drive the solder scraper base 53 to move to scrape solder. This can accurately control the descent height of the solder scraper 5, reducing the situation where the solder scraper 5 fails to scrape solder liquid due to insufficient descent height, and also reducing the situation where the solder scraper 5 is too deep and a large amount of solder liquid is scraped out, thus reducing waste.

[0058] The lifting assembly is equipped with a buffer assembly, which includes a fixed plate 7, a buffer spring 71 and a buffer plate 72. The fixed plate 7 is fixed to the bottom side of the lifting seat 22, the top end of the buffer spring 71 is fixed to the bottom side of the fixed plate 7, and the buffer plate 72 is installed at the bottom end of the buffer spring 71.

[0059] When the lifting drive 23 drives the lifting seat 22 and the tin-dipping seat 3 to descend, the buffer plate 72 abuts against the top side of the machine base 1, and the buffer spring 71 is compressed, thereby slowing down and buffering the lifting seat 22. This reduces the possibility of the coil pins or conduction rods 61 entering the tin-dipping box 12 too deeply due to the excessively fast descent speed of the tin-dipping seat 3, thus reducing waste and saving costs.

[0060] The top side of the machine base 1 is provided with a movable frame 15, and the coil loading frame 13 is slidably connected to the movable frame 15. The coil loading frame 13 slides in the horizontal direction, and the sliding direction of the coil loading frame 13 is perpendicular to the sliding direction of the transverse seat 2. The side wall of the movable frame 15 is provided with a transfer drive 16 for driving the coil loading frame 13 to slide horizontally. The transfer drive 16 is a rodless cylinder. The drive end of the transfer drive 16 is connected to the coil loading frame 13. The moving path of the coil loading frame 13 intersects with the moving path of the transverse seat 2.

[0061] After the coil removal component 31 removes the coil from the coil loading rack 13, the transfer drive component 16 can drive the coil loading rack 13 to slide horizontally, causing the coil loading rack 13 to deviate from the moving path of the transverse seat 2. The operator can then place the coil into the coil loading rack 13 at the position after the coil loading rack 13 has been moved out. The increased operating space after the coil loading rack 13 has been moved out makes it easier for the operator to place the coil, thus speeding up the coil placement and improving the tinning efficiency.

[0062] The implementation principle of the coil pin tinning device in this application embodiment is as follows: When tinning is required, the coil can be placed in the coil loading rack 13, and the horizontal moving seat 2 is driven to move horizontally close to the coil loading rack 13. The coil is picked up by the coil picking member 31, and then the horizontal moving seat 2 is moved directly above the tinning box 12. The lifting drive member 23 drives the lifting seat 22 to descend, so that the lead wire of the coil is immersed in the tinning box 12, thereby performing tinning. At the same time as tinning, the coil can be placed on the coil fixing rod 14. After tinning is completed, the coil on the coil picking member 31 can be removed, and the horizontal moving seat 2 can be moved again to pick up the coil. It is not necessary to put the coil into the coil picking member 31 one by one before tinning, thereby shortening the coil placement time and improving tinning efficiency.

[0063] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
