Description

Cable coating device and coating method Technical Field

[0001] This invention relates to the field of cable processing technology, and more particularly to a cable coating device and coating method. Background Technology

[0002] During wire harness processing, to match the design of the circuit board, the two ground wires in the wire harness need to be positioned with the solder points on the circuit board. However, the placement of the ground wires needs to be adjusted according to actual working requirements. For example, in the special case shown in Figure 1, the cable 900 to be processed is significantly different from the conventional cable structure. On this cable 900, the two ground wires 910 located on both sides of the cable end 920 need to be positioned opposite each other and symmetrical about the axis of the cable body 930 (including the neutral and live wires).

[0003] Before soldering, the ground wires 910 need to be tinned. Since the two ground wires 910 of the cable 900 to be processed are arranged opposite each other, the ground wires 910 need to be inserted vertically into the solder spoon during the tinning process. Therefore, two tinning processes are required to ensure that both ground wires 910 are tinned for successful soldering to the circuit board. The tinning operation includes the following detailed steps: The cable 900 to be processed is fixedly mounted on the tinning carrier; the solder spoon containing solder is raised, immersing one ground wire 910 into the solder; then the solder spoon is lowered, removing the ground wire 910 from the solder; finally, the tinning carrier is rotated 180° to perform the tinning process for the other ground wire 910. For a single cable 900 to be processed, the above tinning operation results in uniform tinning and stable quality.

[0004] However, with technological advancements, the speed of tinning the cables 900 to be processed needs to be increased to improve production efficiency. Considering the above factors, the problem of excessively long tinning times in the two tinning processes becomes apparent. This indicates that the existing tinning process is not conducive to the large-scale mass production of the cables 900 to be processed, and there is an urgent need for a cable coating device and coating method to improve the efficiency of the tinning process. Summary of the Invention

[0005] The purpose of this invention is to provide a cable coating device and coating method to solve the problem of low efficiency in coating operations.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A cable coating device is used to coat the ground wire of a cable to be processed with coating. It includes a coating furnace, a cable carrier, and a coating module. The coating furnace contains the coating. The cable to be processed is detachably mounted on the cable carrier. The coating module includes at least one coating scoop, which has a receiving tank for holding the coating. The level of the coating in the receiving tank is higher than the top of the tank. The coating scoop can move between a coating position and a replenishment position. When the coating scoop is in the replenishment position, it extends into the coating furnace. When the coating scoop is in the coating position, the top of the receiving tank is within a working plane, and the ground wire of the cable to be processed, located within the working plane, is immersed in the coating contained in the receiving tank. The working plane is parallel to a horizontal plane.

[0008] As a preferred technical solution for the cable coating device, the cable carrier is used to fix the cable to be processed at the processing position, and the cable to be processed at the processing position is located within the working plane.

[0009] As a preferred technical solution for the cable coating device, two coating spoons are provided. When the coating spoon is located at the coating position, the two coating spoons are respectively located on both sides of the cable to be processed at the processing position.

[0010] As a preferred technical solution for the cable coating device, the coating module further includes a lifting block and a module frame. Both coating scoops are mounted on the lifting block. The lifting block can reciprocate relative to the module frame in the driving direction to drive the two coating scoops to move between the coating position and the replenishing position.

[0011] As a preferred technical solution for the cable coating device, each coating spoon is fixedly connected to a positioning plate, and the positioning plate is movably installed on the lifting block and can move relative to the lifting block in the horizontal plane.

[0012] As a preferred technical solution for the cable coating device, the lifting block has a mounting surface; the positioning plate has an elongated hole through it, the extension direction of the elongated hole is parallel to both the horizontal plane and the mounting surface, the locking pin can pass through the elongated hole and selectively lock onto the mounting surface, and the two positioning plates can move towards or away from each other along the extension direction of the elongated hole.

[0013] As a preferred technical solution for the cable coating device, the driving direction is perpendicular to the horizontal plane, and the opening of the coating furnace faces upward.

[0014] As a preferred technical solution for the cable coating device, the cable carrier includes a conductor pressure block, which is disposed above the cable to be processed at the processing position, and is used to stop the upward moving cable to be processed by the cable to be processed abutting against the conductor pressure block.

[0015] As a preferred technical solution for the cable coating device, the cable carrier includes a support frame and a pressing device that is detachably fastened to the support frame. The support frame and the pressing device form a positioning through hole, through which the cable to be processed can pass. The conductor pressure block is fixed to the pressing device.

[0016] The coating application method, applied to the aforementioned cable coating device, includes the following steps:

[0017] S10: Fill the paint furnace with the paint, move the paint scoop to the replenishment position, and fill the receiving tank with the paint;

[0018] S20: Place the cable to be processed on the cable carrier, and adjust the position of the ground wire on the cable to be processed until all the ground wires are located within the working plane;

[0019] S30: The cable to be processed is fixedly positioned using the cable carrier;

[0020] S40: Move the paint spoon to the paint application position so that the paint wets all the ground wires;

[0021] S50: After the dipping time has elapsed, the paint scoop is moved back to the replenishment position, and the cable to be processed is removed from the cable carrier.

[0022] The beneficial effects of this invention are:

[0023] This cable coating device, utilizing a cable carrier, achieves the positioning of the cable to be processed, fulfilling the requirement for fixed positioning. The paint scoop, movable between the coating and replenishment positions, allows for paint replenishment at the replenishment position and coating of the ground wire at the coating position. When the top of the receiving tank is flush with the ground wire, the ground wire's immersion in the paint within the tank ensures contact with the paint above the tank top, enabling batch wetting of ground wires within the working plane and achieving coating operation in the horizontal plane. Unlike conventional vertical coating operations, this design ignores the depth requirement of the paint scoop, expanding the contact space between the ground wire and the paint. Combined with optimized placement of ground wires on the cable to be processed, it allows for a single coating operation on all ground wires. These improvements reduce the number of coating operations from multiple to one, significantly improving the coating efficiency of the processed cables.

[0024] This coating method, with the assistance of a cable coating device, enables a one-time coating operation on all ground wires located on the working plane after all ground wires are in the working plane. The above workflow is simple and reliable, the process is short and the workload is small, the coating operation is effective and the risk of omission is low, and it can also improve the efficiency of coating operation.

[0043] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0044] As shown in Figures 1 to 7, this embodiment provides a cable coating device for coating the ground wire 910 on the cable 900 to be processed with coating 800. The cable coating device includes a coating furnace 400, a cable carrier 100, and a coating module 500. The coating furnace 400 contains coating 800. The cable 900 to be processed is detachably installed on the cable carrier 100. The coating module 500 includes at least one coating spoon 510, which has a receiving tank for holding the coating 800. The liquid level of the coating 800 in the receiving tank is higher than the top of the receiving tank. The coating spoon 510 can move between a coating position and a replenishment position. When the coating spoon 510 is in the replenishment position, the coating spoon 510 extends into the coating furnace 400. When the coating spoon 510 is in the coating position, the top of the receiving tank is located in the working plane, and the ground wire 910 on the cable 900 to be processed, located in the working plane, is immersed in the coating 800 contained in the receiving tank. The working plane is parallel to the horizontal plane.

[0045] In this embodiment, the coating 800 in the receiving tank is higher than the limit of the top of the receiving tank, which can achieve full wetting of the surface of the ground wire 910.

[0046] Specifically, the coating 800 is tin. Due to the inherent properties of high-temperature tin, the surface tension of the coating 800 in liquid state is relatively large. Therefore, when the coating spoon 510 scoops the coating 800 out of the coating furnace 400, the liquid level of the coating 800 will be higher than the top of the receiving tank. These characteristics ensure that when the end of the ground wire 910 is flush with the top of the receiving tank on the coating spoon 510, the ground wire 910 can still be immersed in the coating 800.

[0047] This cable coating device, with the help of the cable carrier 100, achieves the positioning of the cable 900 to be processed, satisfying the fixed positioning requirements of the cable 900. The paint spoon 510, which can move between the coating position and the replenishment position, allows the paint spoon 510 to replenish paint 800 at the replenishment position and allows the ground wire 910 to be coated at the coating position. When the top of the receiving tank is flush with the ground wire 910, the limitation that the ground wire 910 can be immersed in the paint 800 contained in the receiving tank ensures that the ground wire 910 can contact the paint 800 above the top of the receiving tank, thereby achieving batch wetting of the ground wire 910 located in the working plane by the paint 800, realizing the coating operation of the ground wire 910 in the horizontal plane. Unlike the conventional coating operation of the ground wire 910 in the vertical direction, this design ignores the depth requirement of the paint spoon 510, expanding the contact space between the ground wire 910 and the paint 800. By optimizing the arrangement of the ground wires 910 on the cable 900 to be processed, it is possible to apply coating to all ground wires 910 in one go. Through the above improvements, the number of coating operations can be reduced from multiple times to one, thereby significantly improving the coating efficiency of the cable 900 to be processed.

[0048] When the working plane contains both the top of the receiving groove and the cable 900 to be processed, the ground wire 910 on the cable 900 located in the working plane can be located in the same plane as the top of the receiving groove. This allows the action of the ground wire 910 immersing in the coating 800 to occur in the working plane, thereby achieving accurate control of the working status of the cable coating device.

[0049] In this embodiment, one end of the cable 900 to be processed is provided with a cable end 920. A cable body 930, coaxial with the cable 900, and two ground wires 910 extend from the cable end 920. The two ground wires 910 are symmetrically arranged about the axis of the cable body 930. With the above structure, the cable 900 to be processed does not require optimization of the ground wire 910's position in the aforementioned cable coating device, thus meeting the work requirement of applying coating to all ground wires 910 in a single operation.

[0050] In other embodiments of this example, the specific structure of the cable 900 to be processed, the number of ground wires 910, and the arrangement of the ground wires 910 need to be selected according to the actual working conditions. When using the above-mentioned cable coating device for coating operation, the specific structure of the cable 900 to be processed needs to be considered, and all ground wires 910 should be adjusted to the working plane with minimal position adjustment as the benchmark. The specific position adjustment operation of the ground wires 910 shall be adjusted by those skilled in the art according to the actual situation, and the specific adjustment method is a conventional technical means in the art, which will not be described in detail here.

[0051] In this embodiment, the cable carrier 100 is used to fix the cable 900 to be processed at the processing position, and the cable 900 to be processed at the processing position is located in the working plane.

[0052] With the above settings, the fixed position of the cable 900 to be processed is defined and the arrangement direction of the cable 900 to be processed is standardized. This allows the position adjustment of the ground wire 910 to be completed in advance before the installation of the cable 900, thereby ensuring that the ground wire 910 can be wetted in batches and significantly improving the efficiency of the dipping operation.

[0053] Furthermore, two paint scoops 510 are provided. When the paint scoops 510 are in the dipping position, the two paint scoops 510 are respectively located on both sides of the cable 900 to be processed at the processing position. The limitation of the two paint scoops 510 being located on both sides of the cable 900 to be processed allows paint 800 to be provided on both sides of the cable 900 to be processed. The above limitation allows all ground wires 910 located in the working plane to complete the paint dipping operation at one time, ensuring that the batch wetting of ground wires 910 can be successfully completed.

[0054] Naturally, the height of the two identical paint scoops 510 must always be consistent, thus ensuring that the paint-coating height of the ground wires 910 on both sides of the cable to be processed 900 is consistent.

[0055] Furthermore, the coating module 500 also includes a lifting block 530 and a module frame 540. Both coating scoops 510 are mounted on the lifting block 530. The lifting block 530 can reciprocate relative to the module frame 540 in the driving direction to drive the two coating scoops 510 to move between the dipping position and the replenishing position.

[0056] By setting up the lifting block 530 and the module frame 540, the two paint scoops 510 are driven synchronously, ensuring the accurate positioning of the paint scoops 510 and enabling the paint application action to start and end in a timely manner, thereby ensuring the smooth completion of the paint application operation.

[0057] By placing part of the ground wire 910 outside the paint 800 and immersing part of the ground wire 910 in the paint 800, the ground wire 910 can be partially coated with paint.

[0058] Furthermore, each paint scoop 510 is fixed to a positioning plate 520, which is movably mounted on the lifting block 530 and can move horizontally relative to the lifting block 530. This design allows for fine-tuning of the position of the paint scoop 510 relative to the lifting block 530, thus adjusting the wettable range of the paint 800 when the paint scoop 510 is in the coating position. These improvements not only enable the cable coating device to adapt to various types of cables 900 with different structures, but also allow for fine-tuning of the coating length on the ground wire 910, making the coating process more flexible and significantly expanding its applicability.

[0059] For example, the lifting block 530 has a mounting surface; the positioning plate 520 has an elongated hole 521 through it, the extension direction of the elongated hole 521 is parallel to both the horizontal plane and the mounting surface, the locking pin can pass through the elongated hole 521 and selectively lock to the mounting surface, and the two positioning plates 520 can move towards or away from each other along the extension direction of the elongated hole 521.

[0060] By setting the mounting surface, the range of motion of the positioning plate 520 is limited. At the same time, by limiting the extension direction of the elongated hole 521, the two paint scoops 510 can only move towards or away from each other. While limiting the wettable range of the paint 800, it can also ensure that the local paint application to the ground wire 910 can still be completed smoothly.

[0061] Specifically, the mounting surface is perpendicular to the horizontal plane. The above design plans the movement trajectory of the paint scoop 510, limits the active area of ​​the paint 800's wettable range, and reduces the complexity of adjusting the position of the paint scoop 510.

[0062] In this embodiment, the driving direction is perpendicular to the horizontal plane, and the opening of the paint furnace 400 faces upward. This design optimizes the layout of the paint module 500, reducing the space it occupies and simplifying the lifting block 530's operation of the two paint scoops 510. This facilitates structural optimization of the cable coating device and minimizes its space requirements. Furthermore, this design allows the paint furnace 400 to be positioned directly below the paint scoops 510, enabling the timely collection of paint 800 dripping from the scoops 510. This reduces the rate of paint 800 loss and minimizes environmental pollution, contributing to a cleaner working environment.

[0063] For example, the cable carrier 100 includes a conductor clamping block 111, which is disposed above the cable 900 to be processed at the processing position. The conductor clamping block 111 stops the upward-moving cable 900 from moving against the conductor clamping block 111. The conductor clamping block 111 prevents the cable 900 from shifting upwards under external force, avoiding the possibility of the paint spoon 510 accidentally pushing the cable 900. This effectively prevents the cable 900 from shifting position and reduces the risk of the ground wire 910 tilting.

[0064] Specifically, the conductor clamp 111 is made of titanium alloy. The titanium alloy conductor clamp 111 does not stick to solder, which can prevent the coating 800 from adhering to the conductor clamp 111. This can reduce the loss of coating 800 and avoid the situation where the positioning ability of the cable 900 to be processed is affected by the coating 800 clumping.

[0065] Furthermore, the cable carrier 100 includes a support frame 120 and a pressing device 110 detachably fastened to the support frame 120. The support frame 120 and the pressing device 110 form a positioning through hole, through which the cable to be processed 900 can pass. The conductor pressing block 111 is fixedly connected to the pressing device 110. Specifically, the conductor pressing block 111 is integrally formed on the pressing device 110. Through the detachable connection design between the support frame 120 and the pressing device 110, selective fixing of the cable to be processed 900 within the positioning through hole can be achieved. The above structure is simple and reliable, occupies little space, and has high connection stability, thus successfully achieving the positioning purpose of the cable to be processed 900.

[0066] In this embodiment, the cable coating device also includes a device frame 300, a coating oven 400 and a module frame 540, all of which are fixedly installed on the device frame 300. A drive unit 210 is fixedly connected to the device frame 300, and the output end of the drive unit 210 is connected to a connecting frame 220. The drive unit 210 is used to drive the connecting frame 220 to move relative to the device frame 300. The support frame 120 is detachably connected to the connecting frame 220. The setting of the drive unit 210 enables the cable carrier 100 to make fine adjustments to its position.

[0067] In this embodiment, the vertical direction of the cable coating device is vertical. In the horizontal plane, the length direction of the cable 900 to be processed, mounted on the cable carrier 100, is the same as the front-back direction of the cable coating device, and the extension direction of the elongated hole 521 is the same as the left-right direction of the cable coating device. That is, the two positioning plates 520 move towards or away from each other along the left-right direction of the cable coating device.

[0068] This embodiment also provides a coating application method, applied to the above-mentioned cable coating application device, including the following steps:

[0069] Step 1: Fill the paint oven 400 with paint 800, and move the paint scoop 510 to the replenishment position so that the paint 800 fills the receiving tank.

[0070] Step 2: Place the cable 900 to be processed on the cable carrier 100, and adjust the position of the ground wire 910 on the cable 900 until all the ground wires 910 are located within the working plane.

[0071] Step 3: Use cable carrier 100 to fix and position the cable 900 to be processed.

[0072] Step 4: Move the paint spoon 510 to the paint application position so that the paint 800 soaks all the ground wires 910.

[0073] Step 5: After the dipping time, move the paint spoon 510 back to the replenishment position and remove the cable 900 to be processed from the cable carrier 100.

[0074] This coating method, with the assistance of a cable coating device, enables a one-time coating operation on all ground wires 910 located on the working plane after all ground wires 910 are in the working plane. The above workflow is simple and reliable, the process is short and the workload is small, the coating operation is effective and the risk of omission is low, and it can also improve the efficiency of coating operation.

[0075] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
