Description

Technical Field

[0001] The present invention relates to the technical field of tin plating for horn cable conductors, and particularly to a tin plating machine for horn cable conductors. Background Art

[0002] A horn cable, also known as a speaker cable or audio cable, is a crucial wire connecting an audio amplifier to a speaker. Its core function is to transmit the audio signal output by the amplifier to the speaker, enabling the speaker to convert these electrical signals into sound. To improve the electrical conductivity of the horn cable, enhance its corrosion resistance, and ensure the stability and reliability of the connection, the conductor of the cable is usually tin-plated. This process not only helps protect the conductor from environmental factors but also reduces oxidation, ensuring long-term performance.

[0003] In actual operation, the traditional tin plating method mainly involves stripping the horn cable one by one, and then quickly immersing the horn cable conductor into the molten tin liquid manually or through automated equipment, and then quickly removing it to complete the tin plating process. However, since the horn cable usually contains two closely adjacent wires inside, which are respectively used for the connection of the positive and negative poles, during the process of directly immersing the wire conductor of the horn cable into the tin plating bath, due to the too-close distance between the two wires, when the conductor parts of the two are tin-plated, it is extremely easy for them to be covered by the tin liquid and the conductors on both sides to be adhered together, resulting in poor tin plating effect. At the same time, this adhesion not only affects the quality of tin plating but also may require additional processes to separate the wire ends in the subsequent process, thus increasing the complexity of the work and raising the time cost and labor input. Summary of the Invention

[0004] In order to overcome the above-mentioned drawbacks existing in the prior art, the present invention provides a tin plating machine for horn cable conductors that can effectively avoid the adhesion of conductors during tin plating.

[0005] Technical Solution: A tin plating machine for horn cable conductors includes: A base, which is a carrier for component installation. A sheath layer cutting machine, an insulating layer cutting machine, and a tin plating bath are sequentially arranged on the base from right to left.

A placement groove for placing the horn cable is opened on the bottom plate. A buckle plate is hingedly arranged on the right side of the bottom plate. A torsion spring is arranged between the buckle plate and the corresponding bottom plate. A limit frame that contacts and abuts against the buckle plate is also arranged on the base to make the buckle plate fit with the corresponding bottom plate to fix the horn cable; A placement mechanism is provided on the conveyor. The placement mechanism includes two beveled plates respectively arranged at the limiting frame and the bottom of the conveyor. The two beveled plates on both sides are symmetrically arranged front and back. And a set of guide rods are arranged at the bottom of both the bottom plate and the buckle plate. A front plate is slidably arranged between the guide rods on the buckle plate. A rear plate symmetrically provided with inclined slots is slidably arranged between the guide rods on the bottom plate. Springs are arranged between the rear plate and the front plate and the corresponding guide rods. And the front plate and the rear plate are respectively in contact with and abutted against the beveled plates on the same side; An unfolding mechanism is provided on the rear plate. The unfolding mechanism includes a trapezoidal plate arranged at the bottom of the rear beveled plate. Card frame for separately placing wires are slidably arranged in the inclined slots of the rear plate. Guide frames are symmetrically arranged at the rear side of the rear plate. A pushing block is slidably arranged between the two guide frames on both sides. Springs are arranged between the two ends of the pushing block and the corresponding guide frames. And the pushing block is symmetrically provided with one-word slots. The ends of the card frames are respectively slidably embedded in the one-word slots on the same side. And a convex rod for contacting and abutting against the trapezoidal plate is arranged on the pushing block to push the sliding operation of the corresponding card frames on both sides.

[0006] In a preferred embodiment of the present invention, both the left and right sides of the beveled plate have a bent inclined surface that changes from a straight line segment to an inclined state to adapt to the initial interval between the front plate and the rear plate that are fitted into. Then, the distance between the two is pushed closer by the inclined surface to form a closing operation.

[0007] In a preferred embodiment of the present invention, the sheath layer cutting machine, the insulating layer cutting machine, and the tin plating bath are all composed of a combination of a lifting base and a functional main component, so that the three can perform a lifting operation.

[0008] In a preferred embodiment of the present invention, a feeding mechanism for assisting and placing the horn cables at different processing stages is provided on the base. The feeding mechanism includes a load-bearing frame arranged between the two sides of the base. The top of the load-bearing frame straddles above the conveyor. And a moving block with a hook is slidably arranged on the top of the load-bearing frame for hanging the horn cable bundle.

[0009] In a preferred embodiment of the present invention, the feeding mechanism further includes a detention frame arranged on the right side of the limiting frame for detaining and placing the incoming horn cables. A blocking frame for restricting the discharging position of the horn cables is arranged on the left side of the limiting frame. A set of guiding frames are arranged at intervals up and down on the left side of the load-bearing frame to guide the moving direction of the discharged horn cables.

[0010] In a preferred embodiment of the present invention, side plates are respectively arranged on both sides of the lifting base of the tin plating bath. Guide grooves inclined backward are opened on the side plates. Guide rails are arranged on the outer walls on both sides of the tin plating bath. A scraper for scraping the caked tin liquid layer on the surface of the tin plating bath is slidably arranged between the two guide rails on both sides. Sliders are arranged on both sides of the scraper. The sliders are embedded in the guide grooves on the same side and the two form a sliding fit.

[0011] In a preferred embodiment of the present invention, there is also a triangular plate. Triangular plates are provided on the blade groups of the sheath layer cutting machine and the insulation layer cutting machine. Both side triangular plates are located on the opposite sides between the corresponding blades to guide the discharge of the rubber heads after cutting. Support plates are respectively provided on the outer walls of the sheath layer cutting machine and the insulation layer cutting machine. A centralized frame is placed between the two support plates in an embedded manner. Feeding grooves adapted to each other are provided on both sides of the centralized frame and on the support plates, and the feeding grooves are respectively connected to the triangular plates on the same side.

[0012] In a preferred embodiment of the present invention, there are also clamping plates symmetrically and hingedly arranged at the front of the centralized frame. L-shaped plates that are engaged with the clamping plates on the same side are respectively provided on the support plates to fix the centralized frame between the two support plates.

[0013] Compared with the prior art, the present invention has the following advantages: 1. Through the coordinated work of the placement mechanism and the unfolding mechanism, the present invention uses the limit frame to fix the buckle plate, the hypotenuse plate to limit and push the front plate, and the hypotenuse plate to push the positioning frame, realizing the automatic positioning of the speaker cable during the conveying process without manual intervention. Especially before tin plating, the unfolded positioning frame can accurately separate the two wires bonded together, effectively avoiding the possible tin plating adhesion problem between conductors in the traditional method, and ensuring the tin plating effect and product quality.

[0014] 2. Through the setting of the material transfer mechanism, the present invention provides corresponding support for the speaker cable at different stages. The load-bearing frame and the hook are used to hang the speaker cable bundles to be processed, the retention frame provides a temporary storage space before feeding, and the blocking frame and the guiding frame are responsible for the discharge and drainage of the speaker cable after tin plating, making the entire production process smoother and more efficient, and reducing the operation complexity.

[0015] 3. Through the triangular plate structure provided in the sheath layer cutting machine and the insulation layer cutting machine, the present invention ensures that the cut waste materials (such as the sheath and the insulation layer) can be smoothly discharged and centrally collected, keeping the working area clean and simplifying the subsequent waste material treatment procedure.

[0016] 4. Through the setting of the scraping plate, the present invention synchronously removes the cooled tin liquid layer on the surface of the tin plating bath during the tin plating process of the speaker cable, ensuring the fluidity of the tin liquid in the tin plating bath, and thus guaranteeing the overall tin plating effect of the speaker cable.

Detailed implementation manners

[0030] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent a limitation on the scope of the present invention as defined by the appended claims. Any numerical labels such as first or second are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0031] Embodiment 1: A tin plating machine for a speaker cable conductor, as Figures 1-8 shown, includes: A base 1, which is an installation carrier for each component. On the front side of the top of the base 1, a sheath cutter 11 for removing the outer sheath layer of the speaker cable 101, an insulation cutter 12 for removing the wire insulation layer of the speaker cable 101, and a tin plating bath 13 for tin plating the exposed conductor are arranged in sequence from right to left. A conveyor 14 for conveying the speaker cable 101 from right to left is also arranged in the middle of the base 1. In this embodiment, the conveyor 14 is a plate chain conveyor; Specifically, the above-mentioned sheath cutter 11, insulation cutter 12, and tin plating bath 13 are all composed of a lifting base and the main functional components of the three, so that the three can present a lifting operation. Among them, the cutting parts of the sheath cutter 11 and the insulation cutter 12 are mainly composed of a telescopic driving member and a blade group. The blade group is composed of two blades facing each other front and back, and the telescopic driving member is used to push the corresponding connected blade to move, so that the two blades can be closely attached when cutting is required, thereby realizing the cutting and peeling operations on the speaker cable 101 placed therein.

[0032] Base plates 141 are arranged in a row on the conveyor belt of the conveyor 14. A placement groove 1411 for placing the speaker cable 101 is opened on the base plate 141. The placement groove 1411 trends along the upper and lower edges. A buckle plate 142 is hingedly arranged on the right side of the base plate 141. A torsion spring is arranged between the buckle plate 142 and the corresponding base plate 141. The torsion spring provides the necessary elastic resilience for the subsequent reset of the buckle plate 142. A limit frame 15 that contacts and abuts against the buckle plate 142 is also arranged on the base 1, so that the buckle plate 142 rotates to fit with the corresponding base plate 141, thereby fixing the position of the speaker cable 101; Specifically, see in detail 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.

[0033] 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. 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.

[0034] 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 inclined side plate 21. The trapezoidal plate 31 is located above the tin plating bath 13. In the inclined slots 241 of the rear plate 24, clamping frames 32 for separately placing wires are slidably arranged. On the left and right sides of the rear side of the rear plate 24, guiding frames 33 are symmetrically arranged. A pushing block 34 is slidably arranged between the two guiding frames 33. The pushing block 34 slides in the up and down direction. Springs are arranged between the left and right ends of the pushing block 34 and the corresponding guiding frames 33. And on the pushing block 34, linear slots 341 are symmetrically arranged on the left and right. The ends of the clamping frames 32 are respectively slidably embedded in the linear slots 341 on the same side. And in the middle of the rear side of the pushing block 34, a convex rod 342 for contacting and abutting against the trapezoidal plate 31 is also arranged, which is used to push the sliding operation of the two corresponding clamping frames 32.

[0035] Specifically, as shown in Figure 7 , the inclined slots 241 are in an "eight" shape. Due to the cooperation of the trapezoidal plate 31 and the convex rod 342, the clamping frames 32 change from the initial closed state, and then expand to adapt to the expansion state of the inclined slots 241. Correspondingly, when the front plate 23 and the rear plate 24 approach each other, the closed clamping frames 32 are inserted between the wires during this process, realizing the preliminary expansion and unfolding of the wire part. Further, with the cooperation of the clamping frames 32 and the inclined slots 241, the wires on both sides are completely separated, thus presenting a state where the wires on both sides are unfolded, ensuring that the tin liquid can be covered separately and evenly when tin plating the conductor part, effectively avoiding the occurrence of adhesion, and thus improving the tin plating effect of the speaker cable 101.

[0036] As Figure 1 and Figure 9 shown, a feeding mechanism 4 for assisting and placing the speaker cable 101 at different processing stages is arranged on the base 1. The feeding mechanism 4 includes a bearing frame 41 arranged between the left and right sides of the base 1. The top of the bearing frame 41 straddles above the conveyor 14. And a moving block 42 with a hook 43 is slidably arranged on the top of the bearing frame 41 for hanging the speaker wire bundle 100. And the top part of the bearing frame 41 inclines backward, and a cross bar is arranged between the side walls at the top of the bearing frame 41 at a position in front of the moving block 42, so that the hung speaker wire bundle 100 can have a more stable placement platform.

[0037] As Figure 1 and Figure 9 shown, the feeding mechanism 4 further includes a detention frame 44 arranged on the right side of the limiting frame 15 for detaining and placing the incoming speaker cable 101. On the left side of the limiting frame 15, a blocking frame 45 for restricting the discharging position of the speaker cable 101 is arranged. A group of guiding frames 46 are arranged at intervals up and down on the left side of the bearing frame 41 to guide the moving direction of the discharged speaker cable 101, so as to effectively manage the incoming and outgoing speaker cables 101.

[0038] During use, first place the speaker wire bundle 100 to be processed on the moving block 42 through the hook 43, so that the speaker wire bundle 100 is supported by the load-bearing frame 41 and provided with a placement. Then slide the moving block 42 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 start the conveyor 14, and the staff will sort the speaker wires 101 in the speaker wire bundle 100 one by one and place them in the placement groove 1411 of the bottom plate 141, and the remaining speaker wires 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.

[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 10 shown, it further includes side plates 5 respectively arranged on the left and right sides of the lifting base of the tin plating bath 13. Guide grooves 51 inclined backward are formed on the side plates 5. Guide rails 52 are arranged on the outer walls on the left and right sides of the tin plating bath 13. A scraper 53 for scraping the caked tin liquid layer on the surface of the tin plating bath 13 is slidably arranged between the two guide rails 52. Sliders 54 are arranged on the left and right sides of the scraper 53. The sliders 54 are embedded in the guide grooves 51 on the same side and the two form a sliding fit.

[0040] During the tin plating process of the horn cable 101, the lifting base of the tin plating bath 13 will synchronously drive the main part of the tin plating to rise. At the same time, the scraper 53 moves upward synchronously with the tin plating bath 13, and the sliders 54 on both sides of the scraper 53 slide along the guide grooves 51 on the same side accordingly. Affected by the inclination trend of the guide grooves 51, the scraper 53 is thus pushed to move backward on the guide rails 52, so that the bottom of the scraper 53 contacts the tin liquid on the surface of the tin plating bath 13, to scrape the caked tin liquid after cooling on the surface of the tin plating bath 13, thereby removing the tin liquid layer that is difficult to flow, facilitating the tin plating treatment of the conductor of the horn cable 101.

[0041] As Figure 11 and Figure 12 shown, it further includes triangular plates 6. Triangular plates 6 are arranged on the blade groups of the sheath layer cutting machine 11 and the insulation layer cutting machine 12. The two triangular plates 6 are both located on the opposite sides between the corresponding blades, for guiding the discharge of the rubber heads after cutting; Support plates 61 are respectively arranged on the outer walls of the sheath layer cutting machine 11 and the insulation layer cutting machine 12. A centralized frame 62 is placed between the two support plates 61 in an embedded manner. Feeding grooves 611 adapted to each other are formed on the left and right sides of the centralized frame 62 and on the support plates 61, and the feeding grooves 611 are respectively connected to the triangular plates 6 on the same side, ensuring the smooth progress of the cutting process and the orderly discharge of the waste after cutting, reducing machine failures caused by waste accumulation.

[0042] As Figure 11 and Figure 12 shown, it further includes clamping plates 63 symmetrically hinged to the front part of the centralized frame 62. L-shaped plates 64 engaged with the clamping plates 63 on the same side are respectively arranged on the support plates 61, for fixing the centralized frame 62 between the two support plates 61, ensuring that the centralized frame 62 will not be displaced during the cutting process, thus ensuring the accuracy of the cutting and the stability of the centralized frame 62.

[0043] 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.

[0044] 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.
