Description

Technical Field

[0001] This utility model relates to the field of tin coating technology for electronic components, and specifically to a high-efficiency tin coating device for the production of electronic components. Background Technology

[0002] In the production of electronic components, tin coating is a key process. Its purpose is to form a uniform and dense tin layer on the conductive parts of the components, such as pins, terminals, and contacts, to improve conductivity, solderability, corrosion resistance, and oxidation resistance, thereby ensuring the stability and reliability of the components in circuit connections.

[0003] Manual operation is the main reason for unstable tin coating quality. When operators immerse electronic components in molten solder, it is difficult to maintain consistent force and angle. If the force is too small, the contact depth between the component pins and the molten solder will be insufficient, resulting in an excessively thin tin coating or even localized missed coating. During subsequent soldering, insufficient solder can easily lead to cold solder joints, affecting the stability of the circuit connection.

[0004] Traditional clamping mechanisms often use fixed-size designs, which makes it difficult to meet the production needs of electronic components with various specifications and sizes. The clamping force depends on manual control. When the force is too small, the components are prone to loosening and falling off during movement or tinning, which not only causes product scrap but may also fall into the molten solder and contaminate the solder or jam the equipment. Excessive force will cause damage to the components. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-2This utility model provides a technical solution: a high-efficiency tin coating device for electronic component production, including a support platform 1, an L-shaped frame 3 fixedly connected to the rear end of the upper surface of the support platform 1, a processing platform 2 fixedly connected to the lower end of the surface of the L-shaped frame 3, a fixing plate 4 provided at the rear end of the upper surface of the processing platform 2, a pressing component 5 fixedly connected to the upper surface of the fixing plate 4, a clamping component 6 provided at the lower end of the surface of the fixing plate 4 near the lower end of the pressing component 5, and a molten solder chamber 9 fixedly connected to the surface of the processing platform 2. A cooling chamber 10 is fixedly connected to one side of the molten tin chamber 9. A scum removal assembly 7 is fixedly connected to the upper end of both the molten tin chamber 9 and the cooling chamber 10. The clamping assembly 6 includes a clamping frame 601. Limiting posts 607 are fixedly connected to the opposite faces of the two ends of the lower inner wall of the clamping frame 601. A first clamping rod 602 is slidably connected to one end of the outer side of the limiting post 607, and a second clamping rod 608 is slidably connected to the other end of the outer side of the limiting post 607. A fixing rod 604 is fixedly connected to the center of the outer side of the limiting post 607, and an electric push rod 60 is fixedly connected to one side of the fixing rod 604. 3. The output end of the electric push rod 603 passes through the fixed rod 604 and is fixedly connected to the inner wall surface of the second clamping rod 608. The upper surface of the fixed rod 604 is rotatably connected to the first connecting rod 605. Both ends of the upper surface of the first connecting rod 605 are rotatably connected to the second connecting rod 606. The other end of the second connecting rod 606 is rotatably connected to the upper surface of one end of the first clamping rod 602 and the second clamping rod 608, respectively. Both ends of the lower surface of the first clamping rod 602 and the second clamping rod 608 are fixedly connected to the clamping plates 609. Based on the support platform 1, the L-shaped frame 3 is fixed. At the rear end of the upper surface of the support platform 1, the processing platform 2 and other related components are provided for installation support. The processing platform 2 serves as the main working area for tinning and cooling operations. It is started by an electric push rod 603, whose output end drives the second clamping rod 608 to move along the limiting post 607 toward the fixing rod 604. At the same time, thanks to the linkage of the first connecting rod 605 and the second connecting rod 606, the first clamping rod 602 slides toward the second clamping rod 608 in a synchronous manner. With the help of the clamping plate 609, the components to be tinned are precisely clamped, ensuring that the surface to be tinned is vertically downward, which is convenient for subsequent tinning.

[0026] Reference Figure 3The pressing component 5 includes a fixed base 501, with a gear 502 disposed on the inner wall of the fixed base 501. One end of the gear 502 is rotatably connected to the inner wall of the fixed base 501, and the other end of the gear 502 extends to the outside and is fixedly connected to a rotating column 504. A pressing handle 505 is fixedly connected to the surface of the rotating column 504. Both sides of the gear 502 are meshed with cylindrical racks 503. The lower end of the cylindrical rack 503 passes through the fixed base 501 and is fixedly connected to the upper surface of the clamping frame 601, while the upper end of the cylindrical rack 503 passes through the upper surface of the fixed base 501. A baffle 507 is fixedly connected. A spring 506 is fixedly connected to the lower surface of the baffle 507 near the outer side of the cylindrical rack 503. The lower end of the spring 506 is fixedly connected to the upper surface of the fixed base 501. By operating the pressing handle 505 of the pressing assembly 5, the rotating column 504 drives the gear 502 to rotate. The cylindrical racks 503 on both sides that mesh with it are driven downward, so that the clamping frame 601 and the components are pressed down. This allows the tin-coated surface of the components to be immersed in the tin liquid in the tin liquid chamber 9 to complete the tin coating. The spring 506 is compressed to prepare for the reset after the tin coating is completed.

[0027] Reference Figure 4 , Figure 5 The slag removal assembly 7 includes two threaded rods 705, which are distributed on both sides of the upper end of the molten tin chamber 9. A rotating seat 703 is fixedly connected to one end of each threaded rod 705. A drive motor 701 is fixedly connected to the outer side of the rotating seat 703 closest to one side. A belt 702 is driven through the outer surface of the rotating seat 703. Sliding blocks 704 are threadedly connected to the surfaces of the threaded rods 705. A scraper support frame 706 is fixedly connected to the surface of the sliding blocks 704. The lower surface of the scraper support frame 706... A fixed elastic scraper 707 is connected, and the slag removal component 7 operates continuously or as needed. The drive motor 701 drives the rotating seats 703 on both sides and the threaded rod 705 to rotate via the belt 702. The sliding block 704 drives the scraper support frame 706 and the elastic scraper 707 to move horizontally. After the tin coating is completed, the spring 506 drives the clamping frame 601 to move upward and reset. The servo motor 13 drives the fixed plate 4 to move horizontally again, moving it above the cooling chamber 10. The pressing component 5 repeats the action to immerse the pins into the cooling chamber 10 and accelerate the solidification of the tin layer.

[0028] Reference Figure 6A servo motor 13 is fixedly connected to one side of the upper end of the L-shaped frame 3. A lead screw 14 is fixedly connected to the output shaft end of the servo motor 13. The other end of the lead screw 14 passes through the upper end of the fixed plate 4 and is rotatably connected to the other end of the L-shaped frame 3. Sliding grooves 17 are provided on both sides of the fixed plate 4. A sliding rod 15 is provided on the upper and lower opposite surfaces of the inner wall of the sliding groove 17. The sliding rod 15 passes through the rear end of the clamping frame 601 and is fixedly connected to the bottom of the sliding groove 17. A sliding rod 26 is provided on the lower opposite surface of the L-shaped frame 3. The sliding rod 26 passes through the lower rear surface of the fixed plate 4 and is fixedly connected to the other end of the L-shaped frame 3. The servo motor 13 drives the lead screw 14 to rotate, so that the fixed plate 4 moves along the sliding rod 26 towards the solder cavity 9 until the clamped component is directly above the solder cavity 9. At the same time, the clamping frame 601 can maintain stability along the sliding rod 15 in the sliding groove 17 to ensure positioning accuracy.

[0029] Reference Figure 4 , Figure 6 Both the molten tin chamber 9 and the cooling chamber 10 are fixedly connected to the front side of a slag discharge connecting plate. A slag collection box 12 is provided on the upper surface of the support platform 1 near the lower end of the slag discharge connecting plate at the front end of the molten tin chamber 9 and the cooling chamber 10. U-shaped plates 11 are fixedly connected on both sides of the upper surface of the support platform 1 near the slag collection box 12. The slag collection box 12 is slidably connected to the inner wall of the U-shaped plate 11. By scraping off the slag from the surface of the molten tin, the slag falls into the slag collection box 12 through the slag discharge connecting plate, ensuring the purity of the molten tin and reducing the probability of poor soldering. When the slag collection box 12 is full, it can be pulled out along the U-shaped plate 11 for cleaning, ensuring the continuous operation of the device. A sliding groove 17 is provided at the rear end of the upper surface of the processing platform 2. The lower end of the fixed plate 4 is slidably connected to the inner wall of the sliding groove 17. A limit plate is fixedly connected to the top of the fixed plate 4. Support legs 8 are fixedly connected to the four corners of the lower surface of the support platform 1. The sliding groove 17 maintains stable left and right movement, ensuring positioning accuracy, and the support legs 8 ensure stability during operation.

[0030] The working principle and usage process of this utility model are as follows: Based on the support platform 1, the support legs 8 provide stable support for the entire device, ensuring that there is no shaking during operation. The L-shaped frame 3 is fixed to the rear end of the upper surface of the support platform 1, providing installation support for the processing platform 2 and other related components. The processing platform 2 serves as the main working area for tinning and cooling operations. When tinning electronic components, the components are first clamped and fixed. This is achieved by activating the electric push rod 603 in the clamping assembly 6, whose output end drives the second clamping rod 608 to move along the limiting post 607 towards the fixing rod 604. Through the linkage of the first connecting rod 605 and the second connecting rod 606, the first clamping rod 602 slides synchronously towards the second clamping rod 608 along the limiting post 607. The clamping plate 609 on the lower surface of the first clamping rod 602 and the second clamping rod 608 can accurately clamp the component to be tinned, ensuring that the surface of the component to be tinned is vertically downward, preparing for subsequent tinning. After clamping, the component needs to be moved above the molten solder cavity 9. The servo motor 13 on one side of the upper end of the L-shaped frame 3 operates, and its output shaft drives the lead screw 14 to rotate. The lead screw 14 passes through the upper end of the fixed plate 4. Under the action of the lead screw 14, the fixed plate 4 will move horizontally towards the molten solder cavity 9 along the sliding rod 16 on the opposite side of the lower end of the L-shaped frame 3. At the same time, the sliding rod 15 in the sliding grooves 17 on both sides of the fixed plate 4 passes through the rear end of the clamping frame 601, and the clamping frame 601 can move smoothly along the sliding rod 15. When the component reaches directly above the molten solder cavity 9, it is pressed down by the pressing component 5. In the current tinning operation, the operator rotates the pressing handle 505, causing the rotating column 504 and the gear 502 fixed to one end of the rotating column 504 to rotate. The cylindrical racks 503 meshing on both sides of the gear 502 move downward under the drive of the gear 502, thereby driving the clamping frame 601 and the clamped components to press down together, so that the tinning surface of the components is immersed in the molten tin in the tin chamber 9 to complete the tinning. During this process, the spring 506 on the lower surface of the baffle 507 at the upper end of the cylindrical rack 503 is compressed, storing elastic potential energy, preparing for the reset of the clamping frame 601 after tinning. During the tinning process, the slag removal component 7 will work continuously or as needed to ensure the purity of the molten tin. In the slag removal component 7, the drive motor 701 drives the rotating parts on both sides through the belt 702. The base 703 rotates, causing the threaded rod 705 to rotate. The sliding block 704, which is threaded onto the surface of the threaded rod 705, moves accordingly, thereby moving the scraper support frame 706 and the elastic scraper 707 to scrape away the slag on the surface of the molten solder. The scraped slag falls through the slag discharge connecting plate on the front side of the molten solder chamber 9 into the slag collection box 12 below. The slag collection box 12 is placed inside the U-shaped plate 11 on the upper surface of the support platform 1 and can be slid out along the U-shaped plate 11 for easy cleaning of the slag and to ensure the continuous operation of the device. After the tin coating is completed, the spring 506 releases its elastic potential energy, causing the cylindrical rack 503 to move upward and the clamping frame 601 to move upward and reset. Subsequently, the servo motor 13 drives the fixed plate 4 to move again, transferring the components above the cooling chamber 10.The pressing component 5 repeats the pressing action described above, immersing the tin-coated surface of the component into the cooling chamber 10, accelerating the solidification of the tin layer. The slag removal component 7 at the top of the cooling chamber 10 also performs slag removal based on the same principle, ensuring a clean cooling environment.
