Description

Technical Field

[0001] The present invention relates to the technical field of tinning of speaker cable conductors, and in particular to a tinning machine for speaker cable conductors. Background Art

[0002] Speaker cables, also known as speaker cables or speaker cables, are the key conductors connecting audio amplifiers to speakers. Their core function is to transmit the audio signals output by the amplifier to the speakers, enabling them to convert these electrical signals into sound. To improve the conductivity and corrosion resistance of speaker cables, and to ensure a stable and reliable connection, the conductors are often tinned. This process not only helps protect the conductors from environmental factors but also reduces oxidation, ensuring long-term performance.

[0003] In practice, the traditional tinning method mainly involves stripping the speaker cables one by one, then quickly immersing the speaker cable conductors in molten tin using manual or automated equipment, and then quickly removing them to complete the tinning process. However, since speaker cables usually contain two closely adjacent wires, one for the positive and one for the negative terminals, the distance between the two wires is too close, making it easy for the conductors of the speaker cable to be covered by the tin liquid during tinning, and the conductors on both sides adhere together, resulting in poor tinning results. This adhesion not only affects the quality of the tinning, but may also require additional steps to separate the wire ends in the subsequent process, which increases the complexity of the work and increases time and labor costs. Summary of the Invention

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the present invention provides a speaker cable conductor tinning machine that can effectively avoid the conductor tinning adhesion.

[0011] In a preferred embodiment of the present invention, the sheath layer cutting machine, the insulation layer cutting machine and the tinning pool are all composed of a combination of a lifting base and functional main parts, so that the three can perform lifting operation.

DETAILED DESCRIPTION

[0034] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0035] Example 1: A speaker cable conductor tinning machine, such as Figures 1-8 Shown, including:

[0036] The base 1 is a mounting base for various components. The top front side of the base 1 is provided with, from right to left, a sheath cutter 11 for removing the outer sheath of the speaker cable 101, an insulation cutter 12 for removing the insulation layer of the conductors of the speaker cable 101, and a tinning tank 13 for tinning the exposed conductors. A conveyor 14 is also provided in the middle of the base 1 for conveying the speaker cable 101 from right to left. In this embodiment, the conveyor 14 is a plate chain conveyor.

[0037] Specifically, the above-mentioned sheath layer cutting machine 11, insulation layer cutting machine 12 and tin plating pool 13 are all composed of a lifting base and a combination of the main functional parts of the three, so that the three can perform lifting operations. The cutting parts of the sheath layer cutting machine 11 and the insulation layer cutting machine 12 are mainly composed of a telescopic drive and a blade group. The blade group consists of two blades facing each other in the front and back, and the telescopic drive is used to push the corresponding connected blades to move, so that the blades on both sides can fit tightly when cutting is required, thereby realizing the cutting and stripping operations of the speaker cable 101 placed therein.

[0038] The bottom plate 141 is arranged in an array on the conveyor belt of the conveyor 14. A placement groove 1411 for placing the speaker cable 101 is opened on the bottom plate 141. The placement groove 1411 is in an up-down direction. A pinch plate 142 is hingedly provided on the right side of the bottom plate 141. A torsion spring is provided between the pinch plate 142 and the corresponding bottom plate 141. The torsion spring provides the necessary elastic rebound force for the subsequent reset of the pinch plate 142. A limit frame 15 is also provided on the base 1, which contacts and abuts against the pinch plate 142, so that the pinch plate 142 rotates to fit the corresponding bottom plate 141, thereby fixing the position of the speaker cable 101;

[0039] Specifically, see Figure 3, there is space between the back of the limit frame 15 and the conveyor belt of the conveyor 14, that is, the buckle plate 142 comes into contact with the end of the limit frame 15, and is then squeezed and pushed to rotate on the bottom plate 141, and the torsion spring is deformed accordingly until the buckle plate 142 is completely fitted with the bottom plate 141, and the two are transferred to the back of the limit frame 15 as the conveyor 14 is transported, and the closed buckle plate 142 is abutted and fixed at the same time, limiting the reset of the torsion spring and maintaining the closed state between the buckle plate 142 and the bottom plate 141 to buckle and fix the position of the speaker cable 101, and the upper and lower ends of the buckle plate 142 are provided with a plate body extending forward, thereby further limiting its position with the limit frame 15, ensuring the stability of the position of subsequent operations.

[0040] The placing mechanism 2 is arranged on the conveyor 14. The placing mechanism 2 includes two bevel plates 21 respectively arranged at the limit frame 15 and the bottom of the conveyor 14. The bevel plates 21 on both sides are arranged symmetrically front and back, and the right ends of both are located on the left side of the sheath layer cutting machine 11. A group of guide rods 22 arranged at intervals on the left and right are provided at the bottom of the bottom plate 141 and the gusset plate 142. A front plate 23 is slidably provided between the guide rods 22 on the gusset plate 142. A rear plate 24 symmetrically provided with oblique grooves 241 is slidably provided between the guide rods 22 on the bottom plate 141, so that the rear plate 24 and the front plate 23 can slide along the corresponding guide rods 22 in the front and rear directions, and springs are further provided between the rear plate 24 and the front plate 23 and the corresponding guide rods 22. At the same time, the front plate 23 and the rear plate 24 are also in contact with and abut against the bevel plates 21 on the same side respectively.

[0041] Specifically, see Figure 5 The left and right sides of the bevel plate 21 are both provided with curved bevel surfaces that transform from straight segments into inclined states. When the front plate 23 and the rear plate 24 enter the bevel plate 21, they will first be embedded in the channel portion composed of straight segments. Because the spacing in this area is adapted to the initial spacing between the front plate 23 and the rear plate 24, the two maintain their initial state until the front plate 23 and the rear plate 24 contact the inclined surface on the same side. As a result, the front plate 23 and the rear plate 24 will slide along the inclined surface and be continuously squeezed, thereby narrowing the distance between the two and forming a close-up operation. At this time, the sheath layer of the speaker cable 101 has been stripped off. Cooperating with the subsequent operation of the parts, this action can initially realize the expansion operation of the conductor portion of the speaker cable 101.

[0042] The unfolding mechanism 3 is arranged on the rear plate 24. The unfolding mechanism 3 includes a trapezoidal plate 31 arranged at the bottom of the rear bevel plate 21. The trapezoidal plate 31 is located above the tin plating pool 13. A card frame 32 for separating the wires is slidably provided in the oblique groove 241 of the rear plate 24. A guide frame 33 is symmetrically provided on the rear side of the rear plate 24. A pushing block 34 is slidably provided between the guide frames 33 on both sides. The pushing block 34 slides in the up and down directions. Springs are provided between the left and right ends of the pushing block 34 and the corresponding guide frames 33, and a single-shaped groove 341 is symmetrically provided on the pushing block 34. The ends of the card frame 32 are respectively slidably embedded in the single-shaped groove 341 on the same side, and a protruding rod 342 for contacting and abutting with the trapezoidal plate 31 is further provided in the middle part of the rear side of the pushing block 34 to push the sliding operation of the corresponding card frames 32 on both sides.

[0043] Specifically, see Figure 7 The inclined groove 241 is in the shape of an "eight". Due to the cooperation between the trapezoidal plate 31 and the protruding rod 342, the locking frame 32 is adapted to the expanded state of the inclined groove 241 from the initial closed state and expands. Accordingly, when the front plate 23 and the rear plate 24 are brought closer, the closed locking frame 32 is inserted between the wires in this process, thereby achieving the initial expansion and expansion of the wire part. Further, the cooperation between the locking frame 32 and the inclined groove 241 allows the wires on both sides to be completely separated, thereby presenting the state of the wires on both sides being expanded, ensuring that the tin liquid can be separated and evenly covered when the conductor part is tinned, effectively avoiding the occurrence of adhesion, thereby improving the tinning effect of the speaker cable 101.

[0044] like Figure 1 and Figure 9 As shown, the base 1 is provided with a material conveying mechanism 4 for assisting and placing the speaker cables 101 at different stages of processing. The material conveying mechanism 4 includes a load-bearing frame 41 arranged between the left and right sides of the base 1. The top of the load-bearing frame 41 spans above the conveyor 14, and a moving block 42 with a hook 43 is slidably provided on the top of the load-bearing frame 41 for hanging the speaker wire bundle 100. The top part of the load-bearing frame 41 is tilted backward, and a cross bar is provided between the side walls of the top of the load-bearing frame 41 in front of the moving block 42, so that the hung speaker wire bundle 100 can obtain a more stable placement platform.

[0045] like Figure 1 and Figure 9 As shown, the feeding mechanism 4 also includes a retention rack 44 arranged on the right side of the limit rack 15, which is used to detain and place the speaker cable 101 to be fed, and a shift rack 45 is provided on the left side of the limit rack 15 for limiting the discharge position of the speaker cable 101. A group of guide racks 46 are provided at intervals above and below the left side of the load-bearing rack 41 for guiding the moving direction of the discharged speaker cable 101, thereby effectively managing the feeding and discharging of the speaker cables 101.

[0046] During use, the speaker wire bundle 100 to be processed is first placed on the moving block 42 via the hook 43, so that the speaker wire bundle 100 is supported and placed by the load-bearing frame 41. Then, the moving block 42 is slid to adjust the position of the speaker wire bundle 100 so that the bottom end of the required speaker wire bundle 100 faces the retention rack 44. Then, the conveyor 14 is started, and the staff sorts the speaker cables 101 in the speaker wire bundle 100 one by one and places them in the placement groove 1411 of the bottom plate 141. The remaining speaker cables 101 to be fed are placed in the retention rack 44.As the conveyor 14 is conveying, the speaker cable 101 in the placement groove 1411 is continuously moved from right to left until the gusset 142 comes into contact with the limit frame 15, so that the gusset 142 is squeezed and rotated by the end of the limit frame 15, and as it moves, it is completely closed against the back of the limit frame 15, and the torsion spring is deformed accordingly, so that the gusset 142 is completely engaged with the corresponding bottom plate 141 to fix the placement position of the speaker cable 101. Then the speaker cable 101 moves to the top of the sheath layer cutting machine 11, and the lifting base of the sheath layer cutting machine 11 drives its cutting body to rise, and closes the blades on both sides to cut and peel off the sheath layer outside the speaker cable 101, and then continues to move to the left. When it is close to the middle position of the conveyor 14 When the speaker cable 101 is cut and peeled off by the insulation cutter 12, the front plate 23 and the back plate 24 are pushed by the inclined surface so that the two slide closer to each other on the corresponding guide rod 22, and the springs therein are deformed. Due to the movement of the back plate 24, the positioning frame 32 thereon moves along and contacts the wire of the speaker cable 101. At this time, the two positioning frames 32 are in a fitted state, so that the fitted parts of the two are convex as a whole, and the two positioning frames 32 are in a fitted state. The raised portion between the frames 32 is inserted between the two wires of the speaker cable 101, thereby preliminarily separating the two wires that were originally combined together, and then transporting them to the left, the protruding rod 342 contacts the trapezoidal plate 31 and slides along the inclined surface of the trapezoidal plate 31, thereby pushing the connected pushing block 34 to slide down between the guide frames 33, and the springs on both sides are deformed accordingly, and as the pushing block 34 moves, the positioning frame 32 moves synchronously, and then slides along the corresponding inclined groove 241. Driven by the inclination of the inclined groove 241, the positioning frame 32 slides adaptively in the straight groove 341 synchronously until the protruding rod 342 moves to the end of the inclined surface of the trapezoidal plate 31, so that the protruding rod 342 rests on the bottom of the trapezoidal plate 31, and accordingly, the pushing block 34 and the positioning The frames 32 are moved to the bottom of the guide frame 33, causing the retaining frames 32 on both sides to expand outward, thereby unfolding and separating the two wires. At this time, the speaker cable 101 is also moved directly above the tinning tank 13. From then on, the tinning tank 13 simultaneously tins the conductor portion of the speaker cable 101, completing the tinning operation on the conductor of the speaker cable 101. Finally, the conveyor 14 conveys it to the left to the end of the limit frame 15. Then, the restrictions of the pinch plate 142, front plate 23, and rear plate 24 are released, allowing the speaker cable 101 to be guided outward by the guide frame 46 and pushed out. The stop frame 45 simultaneously blocks the front position of the speaker cable 101 to restrict the direction of the speaker cable 101 and smoothly push it to the left for discharge, thus completing the discharge of the speaker cable 101.

[0047] Example 2: Based on Example 1, Figure 1 and Figure 10 As shown, it also includes side panels 5 respectively arranged on the left and right sides of the lifting base of the tin plating pool 13, and the side panels 5 are provided with guide grooves 51 inclined backward. Guide rails 52 are provided on the left and right outer walls of the tin plating pool 13, and a scraper 53 for scraping off the tin liquid layer agglomerated on the surface of the tin plating pool 13 is slidably provided between the guide rails 52 on both sides. Slide blocks 54 are provided on the left and right sides of the scraper 53, and the slide blocks 54 are embedded in the guide grooves 51 on the same side and the two form a sliding fit.

[0048] During the tin plating process of the speaker cable 101, the lifting base of the tin plating pool 13 will synchronously drive the tinned main part to rise. At the same time, the scraper 53 will move up synchronously with the tin plating pool 13, and the sliders 54 on both sides of the scraper 53 will slide along the guide groove 51 on the same side. Affected by the inclination trend of the guide groove 51, the scraper 53 is pushed to move backward on the guide rail 52, so that the bottom of the scraper 53 contacts the tin liquid on the surface of the tin plating pool 13 to scrape the agglomerated tin liquid on the surface of the tin plating pool 13 after cooling, thereby removing the tin liquid layer that is difficult to flow, and facilitating the tin plating treatment of the conductor of the speaker cable 101.

[0049] like Figure 11 and Figure 12 As shown, a triangle plate 6 is also included. The blade groups of the sheath layer cutting machine 11 and the insulation layer cutting machine 12 are both provided with a triangle plate 6. The triangle plates 6 on both sides are located on the opposite sides between the corresponding blades to guide the discharge of the rubber head after cutting; support plates 61 are respectively provided on the outer walls of the sheath layer cutting machine 11 and the insulation layer cutting machine 12, and a centralizing frame 62 is embedded between the two support plates 61. The left and right sides of the centralizing frame 62 and the support plates 61 are provided with corresponding feed troughs 611, and the feed troughs 611 are respectively connected with the triangle plates 6 on the same side to ensure the smooth progress of the cutting process and the orderly discharge of waste after cutting, thereby reducing machine failures caused by waste accumulation.

[0050] like Figure 11 and Figure 12 As shown, it also includes a clamping plate 63 symmetrically hingedly arranged at the front of the centralizing frame 62, and L-shaped plates 64 are respectively arranged on the support plates 61 to engage with the clamping plates 63 on the same side, so as to fix the centralizing frame 62 between the two support plates 61, ensuring that the centralizing frame 62 will not be displaced during the cutting process, thereby ensuring the accuracy of cutting and the stability of the centralizing frame 62.

[0051] During the process of stripping the speaker cable 101, when the blades of the sheath layer cutter 11 or the insulation layer cutter 12 are closed for cutting, the corresponding triangular plates 6 on both sides fit together, and then the cut rubber head naturally falls onto the triangular plate 6 and slides down along the inclined slope of the triangular plate 6 to the adjacent feed trough 611, thereby entering the interior of the collecting frame 62 to realize the collection and processing of waste. After the collecting frame 62 is used up, the card plates 63 on both sides can be rotated to separate them from the L-shaped plate 64 to release the restriction on the collecting frame 62, and the collecting frame 62 can be taken out for cleaning.

[0052] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
