Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a coating apparatus and method for processing photovoltaic cables with high factor values. Background Technology

[0002] Photovoltaic modules are typically used in environments exposed to rain, sunlight, and extreme temperatures, which places stringent demands on the sealing and waterproofing of the cables and connectors. Extensive testing has revealed that the greater the surface tension of the cable, the stronger the adhesion between the cable surface and the sealant, which necessitates a high surface dyne value. Irradiated cables are produced through radiation cross-linking technology, where the insulation layer is treated with high-energy radiation (such as electron beams or gamma rays) to form a three-dimensional network molecular structure in materials like polyethylene, significantly improving heat resistance, flame retardancy, and mechanical strength.

[0003] Because photovoltaic cables exposed to high radiation levels operate in harsh environments, coatings are typically applied to the outer surface of the cable to improve its protection coefficient. CN119259349A discloses a cable coating device and method. Through a transmission and coating assembly, the device enables automated and uniform coating of the outer surface of the cable to be coated during transmission. However, this coating equipment can only coat a single cable. To increase the number of cables to be coated, an additional coating device or assembly is required, increasing production costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a coating apparatus and method for processing photovoltaic cables with high coefficient of performance irradiation. The coating assembly can simultaneously coat multiple cables, improving coating efficiency and aiming to solve the problems in the prior art.

[0005] To achieve the above-mentioned technical objectives, the specific technical solution of the present invention is as follows: The present invention proposes a coating device for processing high-factor irradiated photovoltaic cables, comprising: a housing, a coating component and a drive component installed inside the housing; the coating component includes an annular frame, which is fixedly installed at the bottom of the housing, and multiple slide rails are uniformly fixedly connected to the annular frame along its circumference, with the slide rails facing the center of the annular frame; a slide seat is slidably connected to the slide rail, and a spray pipe is fixedly installed on the slide seat; wherein, the drive component is used to drive the slide seat to reciprocate on the slide rail, and the slide seat drives the spray pipe to reciprocate to spray the cable surface; wherein, the coating component coats multiple cables simultaneously, and the cables are uniformly distributed along the circumference of the annular frame and located between two adjacent slide rails.

[0006] As a preferred embodiment of the present invention, the surface of the spray pipe is symmetrically provided with two rows of nozzles with adjustable angles, and the side of the slide seat is provided with a slide groove, a slider is slidably connected in the slide groove, and a limiting rod for adjusting the nozzle angle is fixedly connected on the slider.

[0007] As a preferred embodiment of the present invention, the limiting rod is provided with a limiting hole that cooperates with the nozzle, and a stop bar is fixedly connected to one end of the slide rail near the annular frame. The stop bar is used to drive the slider to slide, and an elastic element is fixedly connected between the slider and the slide groove.

[0008] As a preferred embodiment of the present invention, the spray pipe is provided with an arc-shaped channel that is connected to the nozzle, and a hollow nozzle seat is fixedly connected to the nozzle. The nozzle seat and the channel are slidably connected in a sealed manner, and a through hole communicating with the inside of the nozzle seat is provided in the center of the channel.

[0009] As a preferred embodiment of the present invention, the ring frame is equipped with a plurality of positioning wheel sets for positioning the cable, and the slide is fixedly connected with a clamping plate for clamping and fixing the spraying pipe.

[0010] As a preferred embodiment of the present invention, the driving assembly includes a slide rod and a reciprocating block slidably connected to the slide rod, and each reciprocating block is hinged to a connecting rod with each slide block.

[0011] As a preferred embodiment of the present invention, the drive assembly further includes a mounting bracket, a slide bar is fixedly mounted on the mounting bracket, a drive motor is fixedly mounted on the mounting bracket, a crank is fixedly connected to the drive motor shaft, and a connecting rod is rotatably connected between the crank and the reciprocating block.

[0012] As a preferred embodiment of the present invention, both ends of the housing are equipped with conveyor wheel sets that correspond one-to-one with the cables, and a hot air fan is installed on the inner wall of the housing.

[0013] As a preferred embodiment of the present invention, the coating assembly is provided with a circular protective shell, which is fixedly installed on the inner wall of the housing; a sealing strip that cooperates with the channel sealing is fixedly installed on the nozzle seat.

[0014] A coating method for processing high-factor irradiated photovoltaic cables includes the following steps:

[0015] Step 1: Pass multiple cables through the corresponding conveyor wheel set at one end of the machine housing, through the corresponding positioning wheel set, and finally out from the corresponding conveyor wheel set at the other end of the machine housing.

[0016] Step 2: Multiple cables are simultaneously transported forward by the conveyor wheel set. During the cable transport process, the drive component drives the slide to slide back and forth on the slide rail, which in turn drives the spraying pipe to move back and forth to spray a protective layer onto the cables on both sides.

[0017] Step 3: In step 2, when the slide block slides on the slide rail to one end near the ring frame, the stop rod drives the limit rod to move, and the limit rod drives the nozzle to slide in the channel, so that the nozzle sprays the back of the cable in an inclined downward direction.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The present invention provides multiple spray tubes on a ring frame, and the drive component can drive the slide to slide back and forth on the slide rail. During the sliding process of the slide, the spray tubes are driven to move back and forth, thereby coating multiple cable surfaces at the same time, which improves the cable coating efficiency.

[0021] 2. This invention features two rows of adjustable nozzles symmetrically arranged on the spray tube. When the spray tube moves close to the ring frame, the nozzles are moved by the stop bar, changing the nozzle angle so that the nozzles can coat the back of the cable, ensuring comprehensive coating of the cable.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example: This example discloses a coating apparatus for processing photovoltaic cables with high factor values, such as... Figures 1-9 As shown, it includes: a housing 1, a coating assembly 2 and a drive assembly 3 installed inside the housing 1. The coating assembly 2 can coat multiple cables 6 simultaneously. The coating assembly 2 includes a ring frame 21, with a base frame 27 fixedly connected to the lower end of the ring frame 21. The base frame 27 is fixedly installed on the bottom of the housing 1 by bolts. Multiple slide rails 24 are evenly fixedly connected to the ring frame 21 along its circumference, with the slide rails 24 facing the center of the ring frame 21. A slide seat 22 is slidably connected to the slide rail 24, and a spray nozzle is fixedly installed on the slide seat 22. The coating pipe 23 is connected to an external spraying machine via a flexible hose. The drive assembly 3 is used to drive the slide 22 to reciprocate on the slide rail 24. The cable 6 is evenly distributed around the annular frame 21 and is located between two adjacent slide rails 24. In this embodiment, there are four spraying pipes 23 and four cables 6. The drive assembly 3 drives the slide 22 to reciprocate, and the slide 22 drives the spraying pipe 23 to reciprocate, so that the four cables 6 are sprayed at the same time, which greatly improves the coating efficiency of the cables 6.

[0034] Preferably, both ends of the housing 1 are equipped with conveyor wheel sets 5 that correspond one-to-one with the cables 6. The conveyor wheel sets 5 are equipped with motors that drive the cables 6 forward. The inner wall of the housing 1 is equipped with hot air fans 7, which are provided with multiple fans that correspond one-to-one with the cables 6. The hot air fans 7 quickly dry the coated cables 6.

[0035] Preferably, the coating component 2 is provided with a circular protective shell 4, which is fixedly installed on the inner wall of the housing 1; the protective shell 4 can prevent paint from splashing.

[0036] Preferably, the ring frame 21 is equipped with multiple positioning wheel sets 25 for positioning the cable 6. There are four positioning wheel sets 25. The positioning wheel sets 25 make the position of the cable 6 accurate and ensure that the spraying pipe 23 is sprayed in place. The slide 22 is fixedly connected with a clamping plate 224 for clamping and fixing the spraying pipe 23. The clamping plate 224 is fixedly installed on the slide 22 by bolt assembly. The clamping plate 224 is an arc plate. The spraying pipe 23 is clamped and fixed on the clamping plate 224 by locking bolts.

[0037] like Figures 5-7 As shown, the surface of the spray pipe 23 is symmetrically provided with two rows of adjustable nozzles 233, with four nozzles 233 in each row. During the forward conveying of the cable 6, the spray pipe 23 moves up and down, and the four nozzles 233 can completely cover the surface of the cable 6 without any missed spraying. The spray pipe 23 is provided with an arc-shaped channel 231 that cooperates with the nozzles 233. A hollow nozzle seat 232 is fixedly connected to the nozzle 233. The nozzle seat 232 is slidably connected to the channel 231. The center of the channel 231 is provided with a through hole 234 that communicates with the inside of the nozzle seat 232. When the nozzle seat 232 slides up and down in the channel 231, the orientation of the nozzles 233 changes accordingly, thereby adjusting the angle of the nozzles 233 and the spraying direction of the nozzles 233 to ensure comprehensive spraying of the cable 6. When the nozzle seat 232 slides in the channel 231, the through hole 234 always communicates with the inside of the nozzle seat 232 to ensure the continuity of spraying.

[0038] The slide block 22 has vertical grooves 221 on both sides, and a slider 222 is slidably connected in the grooves 221. A limiting rod 225 for adjusting the angle of the nozzle 233 is fixedly connected to the slider 222. The limiting rod 225 is parallel to the spray pipe 23 and has a limiting hole 226 that mates with the nozzle 233. The width of the limiting hole 226 is larger than the diameter of the nozzle 233 to prevent the nozzle 233 from getting stuck when the limiting rod 225 moves up and down. A stop bar 26 is fixedly connected to one end of the slide rail 24 near the ring frame 21. The slide block 22 slides... When the slider approaches the ring frame 21, the stop bar 26 pushes the slider 222 to slide. The slider 222 drives the limit bar 225 to move. The movement of the limit bar 225 changes the orientation of the nozzle 233 so that the nozzle 233 can spray the back of the cable 6 (the side facing the inner wall of the ring frame 21). An elastic element 223 is fixedly connected between the slider 222 and the groove 221. The elastic element 223 is a spring and is used to reset the nozzle 233. In its natural state, the nozzle 233 is in the middle position of the groove 231 and is in a horizontal state.

[0039] In practical implementation: such as Figure 8As shown, taking the uppermost spray pipe 23 as an example, when the slide block 22 slides from bottom to top to a position close to the ring frame 21, the height of the spray pipe 23 exceeds the height of the cables 6 on both sides. During the upward movement of the spray pipe 23, it is impossible to spray the back side of the cable 6 (the side facing the inner wall of the ring frame 21), resulting in missed spraying positions. In this embodiment, when the slide block 22 moves to the uppermost position, the stop bar 26 contacts the slider 222, and drives the slider 222 and the limiting rod 225 to move downward. When the limiting rod 225 moves, it drives the nozzle seat 232 to slide downward in the channel 231, thereby adjusting the nozzle 233 to be tilted downward, and the spraying direction is as follows. Figure 8 As indicated by the middle arrow, the nozzles 233 on the two adjacent spray pipes 23 can just spray the back of the cable 6 in place, thus enabling the cable 6 to be fully sprayed.

[0040] Preferably, a sealing strip 235 that seals with the channel 231 is fixedly installed on the nozzle seat 232, ensuring the sealing effect between the nozzle 233 and the channel 231.

[0041] like Figure 9 As shown, the drive assembly 3 includes a mounting bracket 31, a slide rod 33, and a reciprocating block 34 slidably connected to the slide rod 33. The reciprocating block 34 is hinged to each slide seat 22 with a connecting rod 35. The slide rod 33 is fixedly mounted on the mounting bracket 31, which is fixedly connected to the bottom of the housing 1. A drive motor 32 is fixedly mounted on the mounting bracket 31. A crank 36 is fixedly connected to the shaft of the drive motor 32. A connecting rod 37 is rotatably connected between the crank 36 and the reciprocating block 34. The drive motor 32 drives the crank 36 to rotate circumferentially, which drives the reciprocating block 34 to slide back and forth, thereby driving the spray pipe 23 to move back and forth.

[0042] A coating method for processing high-factor irradiated photovoltaic cables, based on the above-mentioned coating apparatus, includes the following steps:

[0043] Step 1: Pass multiple cables 6 through the corresponding conveyor wheel set 5 at one end of the housing 1, through the corresponding positioning wheel set 25, and finally out from the corresponding conveyor wheel set 5 at the other end of the housing 1.

[0044] Step 2: The conveyor wheel set 5 drives multiple cables 6 to be conveyed forward simultaneously. During the conveying process, the drive assembly 3 drives the slide block 22 to slide back and forth on the slide rail 24, which in turn drives the spraying pipe 23 to move back and forth to spray a protective layer onto the cables 6 on both sides.

[0045] Step 3: In step 2, when the slide block 22 slides on the slide rail 24 to one end close to the ring frame 21, the stop rod 26 drives the limit rod 225 to move, and the limit rod 225 drives the nozzle 233 to slide in the channel 231, so that the nozzle 233 sprays the back of the cable 6 in an inclined downward direction.

[0046] Step 4: After the cable 6 is sprayed and dried by the hot air fan 7, it is conveyed out from one end of the housing 1.

[0047] Finally, it should be noted that in the description of this invention, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
