Description

Technical Field

[0001] The present invention relates to the field of electronic wire harness processing, and particularly to an electronic wire harness uniform tin plating mechanism and its processing method. Background Art

[0002] Tin plating of electronic wire harnesses refers to plating a layer of tin on the surface of the wires of the electronic wire harness to improve its electrical conductivity, corrosion resistance, and aesthetics. The main purpose of this process is to protect the wires from the erosion of the external environment and at the same time optimize its electrical conductivity.

[0003] A wire harness two - end batch tin plating device for electronic product production disclosed in Patent No. CN113604763B includes a base, an n - shaped seat, a heating frame, a loading frame, a placing mechanism, and a driving mechanism. A middle part on one side of the base is fixedly connected with the n - shaped seat. The driving mechanism is installed on one side of the n - shaped seat far from the base. The heating frame is fixedly connected between the four inner sides of the n - shaped seat close to the base. The loading frame is fixedly connected to both ends of the heating frame far from the base and is communicated. An appropriate amount of wire harnesses are placed into the placing mechanism, and then an appropriate amount of tin liquid is poured into the loading frame. The tin liquid in the loading frame flows into the heating frame. Start the heating frame, and the heating frame heats the tin liquid. Pull the driving mechanism to move downward. When the driving mechanism moves downward and contacts the placing mechanism, the driving mechanism drives the placing mechanism to operate. The placing mechanism operates to drive the wire harness to reverse for left - end tin plating, and the placing mechanism also drives the wire harness to rotate forward for right - end tin plating. In this way, there is no need for manual tin plating of the wire harness, which is relatively convenient and has high work efficiency.

[0004] In the prior art, the wire harness is placed into the placing mechanism and then the tin liquid is poured in. The driving mechanism drives the placing mechanism to descend to tin - plate the wire harness. However, in a high - temperature environment, the components in the tin plating liquid are more likely to undergo chemical reactions and cause oxidation, forming oxides on the surface layer of the tin plating liquid. At this time, it is necessary for workers to use tools to timely remove the oxides on the surface layer of the tin plating liquid to enable the wire harness to better complete the tin plating. The tin plating liquid will generate toxic gases when heated. Workers going back and forth to remove the oxides on the surface layer of the tin plating liquid will cause harm to the workers' bodies, and it is also very troublesome to manually remove the oxides every time of tin plating, which affects the work efficiency.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. 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 making creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1 - 8 As shown in the figure, the present invention is an electronic wire harness uniform tin plating mechanism and its processing method, including a tin plating tank 1 and support legs 2; it also includes a scraping and cleaning unit arranged in the tin plating tank 1; The support legs 2 are fixedly arranged at the bottom of the tin plating tank 1, and there are four support legs 2, which are respectively arranged at the four corners of the bottom of the tin plating tank 1; The scraping and cleaning unit is arranged in the tin plating tank 1 and includes a driving component, a scraping component 38, a cleaning component 39, a transverse movement component 37 and a fixing component 40; the driving component drives the scraping component 38 to move; the driving component drives the cleaning component 39 to clean the scraping component 38; the driving component drives the transverse movement component 37 to move; the fixing component 40 moves and clamps on the transverse movement component 37; The electronic wire harness is clamped and fixed by the fixing component 40, and then the driving component drives the transverse movement component 37 to move, sending the electronic wire harness above the tin plating tank 1. When the transverse movement component 37 moves, it will also drive the scraping component 38 to move to scrape the tin plating tank 1. When the scraping component 38 reaches one end of the tin plating tank 1, the driving component drives the cleaning component 39 to clean the scraping component 38; The electronic wire harness is clamped by the fixing component 40, and then the driving component drives to drive the transverse moving component 37 to move. The moving transverse moving component 37 drives the fixing component 40 and the electronic wire harness to above the tin plating tank 1. Such a setting is to make it more convenient to carry the electronic wire harness for tin plating, reduce manual handling, keep the workers as far away from the tin plating tank 1 as possible, and avoid workers inhaling the toxic gas in the tin plating tank 1; When the transverse moving component 37 moves, it will drive the scraping component 38 to move. The moving scraping component 38 will scrape the inner surface layer of the tin plating tank 1. Because the tin plating solution in the tin plating tank 1 is heated and undergoes a chemical reaction, an oxide layer is formed on the surface layer. The moving scraping component 38 scrapes the oxide on the surface of the tin plating tank 1, and then places the electronic wire harness to be tin plated into the tin plating tank 1 for tin plating; When the scraping component 38 scrapes the oxide in the tin plating tank 1, these oxides will adhere to the surface of the scraping component 38, which will affect the effect of the next work of the scraping component 38. Therefore, the driving component drives the cleaning component 39 to move, and the moving cleaning component 39 cleans the oxides adhering to the scraping component 38, so that the scraping component 38 can effectively scrape the oxides in the tin plating tank 1 during the next work.

The rotating driving gear 7 makes the driven rod 9 and the turbine on the driven fixed plate 35 rotate. The rotating turbine drives the worm 4 to rotate. The rotating worm 4 makes the moving frame 3 move. The moving frame 3 slides on the limiting column 18 in the sliding box 12. When the moving frame 3 slides to the specified position, it stops moving and compresses the rebound spring 5. When the worm wheel 8 rotates in reverse, the rebound spring 5 will push the moving frame 3 onto the thread of the worm 4 to make the moving frame 3 continue to move.

[0021] Please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown in the figures, the scraping assembly 38 includes a moving groove 22, a pulley 34, a connecting column 19, a connecting block 20 and a decontamination plate 21; Among them, the moving groove 22 is opened on the moving frame 3; there are two moving grooves 22, which are symmetrically arranged on the moving frame 3; the pulley 34 is slidably arranged in the moving groove 22; the connecting column 19 is rotatably arranged on the pulley 34; the connecting block 20 is fixedly connected with the connecting column 19; the decontamination plate 21 is fixedly arranged on the connecting block 20; When the moving frame 3 moves, it drives the pulley 34 and the connecting column 19 in the moving groove 22 to move left and right. The left and right moving connecting column 19 makes the connecting block 20 and the decontamination plate 21 also move left and right. In this way, the decontamination plate 21 can scrape the oxide surface layer in the tin plating tank 1, so that the electronic wire harness on the fixing component 40 can be effectively tinned.

The rotating semi-toothed gear 10 drives the sliding tooth plate 14 to slide on the sliding rod 15 of the support plate 13 and compress the compression spring 16 on the sliding rod 15. The sliding of the sliding tooth plate 14 causes the scraping plate 32 fixed at the bottom to move. When the decontamination plate 21 approaches, the moving scraping plate 32 will clean the decontamination plate 21.

The rotating fixed rotating rod 31 drives the fixed gear 29 to rotate. The rotating fixed gear 29 causes the moving tooth plate 26 to move within the limiting box 28. The two moving tooth plates 26 are arranged in a vertically staggered manner. Therefore, when the fixed gear 29 rotates, the two moving tooth plates 26 will move inward or outward simultaneously, enabling the clamping blocks 30 at the bottom of the moving tooth plates 26 to clamp the electronic wire harness inward or loosen the electronic wire harness outward.

[0024] Please refer to Figure 1 、 Figure 6 and Figure 8 As shown in the figure, a telescopic rod 24 is fixedly connected to the moving frame 3; the bottom of the telescopic rod 24 is fixedly connected to the sliding plate 23; a telescopic motor 25 is fixedly connected to the top of the moving frame 3, and the telescopic motor 25 is communicated with the telescopic rod 24; The telescopic rod 24 is driven to expand and contract by the telescopic motor 25, causing the telescopic rod 24 to drive the sliding plate 23 to slide up and down on the moving frame 3, enabling the clamping block 30 on the sliding plate 23 to send the electronic wire harness into the tin plating tank 1 for tin plating.

[0027] Working principle of the present invention: The electronic wire harness is clamped by the fixing component 40, and then the driving component drives to drive the transverse movement component 37 to move.

The moving scraping component 38 will scrape the surface layer of the tin plating tank 1. Because the tin plating solution in the tin plating tank 1 is heated and undergoes a chemical reaction, an oxide layer is formed on the surface layer. The scraping component 38 moves to scrape the oxide on the surface of the tin plating tank 1, and then the electronic wire harness to be tin plated is placed into the tin plating tank 1 for tin plating; When the scraping component 38 scrapes the oxide in the tin plating tank 1, these oxides will adhere to the surface of the scraping component 38, which will affect the effect of the next work of the scraping component 38. Therefore, the driving component drives the cleaning component 39 to move, and the cleaning component 39 moves to clean the oxides adhering to the scraping component 38, so that the scraping component 38 can effectively scrape the oxides in the tin plating tank 1 during the next work.
