Description

Technical Field

[0001] This utility model relates to the field of tin-dipping machine technology, specifically to a tin-dipping machine with a clamping mechanism. Background Technology

[0002] A tin-dipping machine is a specialized device for tin plating the surface of electronic components. It immerses the electronic components in molten tin, forming a tin layer on their surface, thereby improving the solderability and corrosion resistance of the components. Tin-dipping machines are widely used in electronics manufacturing, semiconductor packaging, and other fields, and are an indispensable piece of equipment in the modern electronics industry.

[0003] During the operation of the tin-dipping machine, the workpieces to be tinned are usually placed facing downwards to be immersed in the tin bath. Therefore, when fixing the tin-dipping workpieces, they need to be fixed from below, which is extremely inconvenient. At the same time, after the tinning process is completed, it is also inconvenient to observe the tin-dined workpieces with the workpieces facing downwards, making it impossible to effectively ensure the quality of the tinning process. Therefore, we propose a tin-dipping machine with a clamping mechanism to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a tin-dipping machine with a clamping mechanism to solve the problems mentioned in the background art, such as the inconvenience of fixing workpieces and the inability to effectively observe the quality of tin plating.

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.

[0024] Please see Figure 1-7 This utility model provides a technical solution: a tin-dipping machine with a clamping mechanism, including a device body 1, a movable seat 2 is provided on the device body 1, the two ends of the movable seat 2 are connected to a first slide rod 3, the first slide rod 3 is installed in the device body 1, and the device body 1 is provided with a lifting component for adjusting the up and down working position of the movable seat 2.

[0025] Furthermore, the lifting assembly includes a first screw 4, a movable block 6, and a support rod 7. The first screw 4 is mounted on the main body 1 of the device via bearings and is located directly below the movable seat 2. The movable block 6 is threadedly connected to the first screw 4, and one end of the support rod 7 is movably connected to the movable block 6. The other end of the support rod 7 is movably connected to the movable seat 2. Two movable blocks 6 are symmetrically arranged on the first screw 4. The threads connecting the first screw 4 and the two movable blocks 6 are in opposite directions. By rotating the first screw 4, the two movable blocks 6 move in opposite directions. In this way, the position of the movable seat 2 can be controlled to rise and fall by the support rod 7.

[0026] Furthermore, the first screw 4 is fixed with handles 5 at both ends, which facilitates the control of the rotation of the first screw 4 from both sides of the device and improves work efficiency.

[0027] A rotating shaft 11 is movably mounted on the movable base 2. A worm gear 10 is fixed on the rotating shaft 11. A worm 9 is connected to the outside of the worm gear 10. The worm 9 is mounted on the drive motor 8. The drive motor 8 is mounted on the movable base 2. Connecting rods 12 are fixed at both ends of the rotating shaft 11. A clamping mechanism 13 is fixed at the outer end of the connecting rod 12.

[0028] Furthermore, a second slide rod 15 is fixed on the clamping mechanism 13, and a second screw 16 is mounted on the clamping mechanism 13 via a bearing. A movable clamping plate 14 is connected through the second screw 16 and the second slide rod 15. The movable clamping plate 14 is threadedly connected to the second screw 16, which can control the movement of the movable clamping plate 14 in a stable position in the clamping mechanism 13 to complete the clamping of the workpiece. A limit rod 17 is fixed on the clamping mechanism 13, which can initially limit the workpiece to facilitate the quick completion of the workpiece fixing work.

[0029] Furthermore, the second slide bar 15 is symmetrically arranged about the second screw 16, and the movable clamping plate 14 forms a moving structure on the clamping mechanism 13 through the second screw 16, ensuring that the movable clamping plate 14 is in a stable and efficient moving state on the clamping mechanism 13.

[0030] Furthermore, the limiting rod 17 includes a fixed sleeve rod 1701, a telescopic top rod 1702, and a spring 1703. The fixed sleeve rod 1701 is vertically fixed on the clamping mechanism 13. The telescopic top rod 1702 is connected inside the fixed sleeve rod 1701. A spring 1703 is provided between the telescopic top rod 1702 and the fixed sleeve rod 1701, so that the limiting rod 17 has a telescopic function. The limiting rods 17 are evenly distributed on the clamping mechanism 13, so that the limiting rods 17 can effectively clamp workpieces of different sizes.

[0031] A heating device 18 is installed on the main body 1 of the device. The heating device 18 is located on the side of the movable seat 2. A molten tin pool 19 is provided inside the heating device 18. A scraper 20 is provided inside the molten tin pool 19, and a cylinder 21 and a third slide rod 22 are connected to it.

[0032] Working principle: When using this tinning machine, first start the drive motor 8, which drives the worm wheel 10 through the worm 9, so that the rotating shaft 11 rotates on the moving seat 2, thereby driving the clamping mechanism 13 to flip through the connecting rod 12. This flips the clamping mechanism 13 to the outside of the main body 1 of the device, and the direction of the clamping mechanism 13 is upward, which makes it convenient to directly install and fix the workpiece to be tinned on the clamping mechanism 13.

[0033] When fixing the workpiece, the workpiece is first placed into the clamping mechanism 13. Since there is a limiting rod 17 and a movable clamping plate 14 on the clamping mechanism 13, the space inside the clamping mechanism 13 can be reduced, and the workpiece can be placed directly into the clamping mechanism 13. Due to the presence of the limiting rod 17 and the movable clamping plate 14, the workpiece can be pre-fixed when it is placed. After the workpiece is arranged and fixed on the clamping mechanism 13, the second screw 16 is rotated to move the position of the movable clamping plate 14, thereby clamping and fixing the workpiece.

[0034] After the workpiece is fixed on the clamping mechanism 13, the drive motor 8 is started again. Through the transmission of the worm 9 and the worm wheel 10, the rotating shaft 11 drives the clamping mechanism 13 to rotate, and the clamping mechanism 13 can be rotated to the top of the molten solder pool 19.

[0035] Then, by rotating the first screw 4 with the throttle 5, the moving block 6 moves on the first screw 4, and the position height of the moving seat 2 can be changed by the support rod 7. During the movement of the moving seat 2, both ends are connected to the device body 1 through the first slide rod 3 to ensure the stable working state of the moving seat 2.

[0036] When the moving seat 2 moves up and down, it drives the clamping mechanism 13 to move up and down, so that the workpiece can be immersed in the tin bath 19 for tin plating. At this time, the position height of the moving seat 2 is at the most suitable position, and then this position can be maintained to perform tin plating work on the same type of batch of workpieces.

[0037] After the workpiece on the clamping mechanism 13 has been immersed in tin, the clamping mechanism 13 is rotated again so that the clamping mechanism 13, along with the tin-immersed workpiece, rotates to an upward position. This makes it easier to observe the quality of the workpiece after tinning. Once it is qualified, the workpiece can be removed and replaced with other workpieces that need to be immersed in tin. The rotation of the clamping mechanism 13 is repeated. Since the position and height of the moving seat 2 are appropriate, the same workpiece can be directly immersed in the molten tin as the clamping mechanism 13 rotates, thus completing the tinning work.

[0038] The above describes the working process of the tin-dipping machine. Any content not described in detail in this manual is existing technology known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
