Technical Field

[0001] This utility model relates to the field of coating technology, specifically to a device for zinc-aluminum-magnesium coating on the surface of a photovoltaic bracket. Technical Background

[0002] Due to the differences in shape of photovoltaic brackets of different specifications, it is difficult to ensure that a completely uniform coating effect can be achieved on the surface of brackets with various complex shapes. In addition, excess solution adhering to the photovoltaic bracket during the coating process will flow and cause uneven coating, so the corrosion resistance of the bracket in harsh environments cannot be fully guaranteed.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] like Figure 1-4As shown, this embodiment provides a zinc-aluminum-magnesium plating device for photovoltaic brackets, including a frame 1. The frame 1 is equipped with a linear drive device 2 and a linear drive device 4. A plating head 41, which is a spray gun, is fixedly installed at the output end of the linear drive device 4. During spraying, the plating solution is sprayed in a divergent manner to expand the plating area for plating the photovoltaic bracket. A rotation-reversing component 21, which is a linear slide, is installed at the output end of the linear drive device 2. The linear drive device 2 drives the rotation-reversing component 21 to move. By installing two sets of rotation-reversing components 21 on the frame 1, adjacent rotation-reversing components 21 rotate in opposite directions and cooperate with each other to reverse the direction of the photovoltaic bracket. Increasing the number of rotation-reversing components 21 increases the number of photovoltaic components that can be plating, thereby improving work efficiency.

[0028] The rotation and reversing assembly 21 includes a base 211, on which a lifting platform 212 is fixedly mounted. An outer rotating cylinder 213 and an inner rotating cylinder 214 are rotatably mounted on the base 211. The outer rotating cylinder 213 is fitted over the inner rotating cylinder 214, and multiple clamping assemblies 215 are rotatably mounted on the outer rotating cylinder 213. A ratchet 216 is fixedly mounted on the outer rotating cylinder 213, a steering component 2140 is fixedly mounted on the inner rotating cylinder 214, and a second ratchet 217 is fixedly mounted on the inner rotating cylinder 214. A rotational power source 218 is fixedly mounted on the lifting platform 212. The rotational power source 218 can be an electric motor, a pneumatic motor, or a hydraulic motor. A bidirectional ratchet 219 is fixedly mounted on the output shaft of the rotational power source 218. By lifting the lifting platform 212, the bidirectional ratchet 219 can engage with the second ratchet 217. The bidirectional ratchet 219 and ratchet 217 engage, the inner rotating cylinder 214 rotates, and the clamping assembly 215 is used to clamp the photovoltaic bracket, so that the photovoltaic bracket can be reversed.

[0029] The frame 1 is equipped with a plating component 3, which includes a truss 31. The truss 31 is slidably connected to the frame 1 and rotatably connected to the outer rotating cylinder 213. Multiple plating heads 32 are fixedly installed on the truss 31. The plating heads 32 are spray guns. When the plating heads 32 perform spraying, the plating solution is sprayed in a divergent manner to expand the plating area. By setting up the truss 31 and multiple plating heads 32, when the clamping component 215 clamps the photovoltaic accessory, both sides of the accessory can be plating when the accessory rotates and reverses.

[0030] A ratchet 216 is fixedly installed on the outer rotating cylinder 213. The bidirectional ratchet 219 can engage and disengage with the ratchet 216. When the bidirectional ratchet 219 engages with the ratchet 216, the clamping assembly 215 is used to clamp the photovoltaic accessories. When the outer rotating cylinder 213 rotates, the clamping assembly 215 is guided by the guide 2140 to realize the rotation and reversal of the clamping assembly 215.

[0031] The platform 211 has a sliding groove 2110, and the outer rotating cylinder 213 is rotatably connected to the sliding groove 2110 to limit the rotation position of the outer rotating cylinder 213 and prevent the rotating cylinder 213 from leaving the platform 211.

[0032] Multiple connectors 2141 are fixedly installed on the inner rotating cylinder 214 to limit the position of the inner rotating cylinder 214 and allow the rotating cylinder 214 to rotate on the base 211.

[0033] The platform 211 is provided with a second sliding groove 2112, and multiple balls 2111 are rotatably installed on the second sliding groove 2112 to reduce the friction between the connecting piece 2141 and the platform 211.

[0034] The connector 2141 engages with the ball bearing 2111 to enable the inner rotating cylinder 214 to rotate.

[0035] The clamping assembly 215 includes a rotating shaft 2151, which is rotatably connected to the outer rotating cylinder 213. A guide member 2152 is fixedly installed at one end of the rotating shaft 2151, and the guide member 2152 is in contact with the inner rotating cylinder 214. Guide wheels 2153 are provided at both ends of the guide member 2152, and an elastic gripper 2154 is fixedly installed at the other end of the rotating shaft 2151. When the guide wheel 2153 passes through the steering member 2140, since two inclined surfaces are formed between the inner rotating cylinder 214 and the steering member 2140, the guide wheel 2153 will rotate around the rotating shaft 2151 when it passes through the first inclined surface. When it reaches the highest point of the steering member 2140, the high point of the guide wheel 2153 will descend along the second inclined surface, so that the low point of 2153 will rotate to the front side, thereby realizing the reversal of the elastic gripper 2154.

[0036] The linear drive device 2 includes a second rotary power source 22, which can be an electric motor, a pneumatic motor, or a hydraulic motor. The second rotary power source 22 is fixedly connected to the frame 1. A bidirectional threaded rod 23 is fixedly installed at the output end of the second rotary power source 22. The bidirectional threaded rod 23 is rotatably connected to the frame 1. A slide block 24 is threaded onto the bidirectional threaded rod 23. A rotation reversing component 21 is provided on the slide block 24. By setting the bidirectional threaded rod 23, the two sets of rotation reversing components 21 on the frame 1 can move in opposite directions or in reverse, which is convenient for clamping photovoltaic brackets of different lengths.

[0037] The elastic gripper 2154 includes a fixing member 2155 and multiple gripping arms 2156. The fixing member 2155 has a slot 2157 and a sliding hole 2158. A sliding rod 2159 is fixedly installed on the gripping arm 2156. An elastic element 25, which is a spring, is provided in the slot 2157. One end of the elastic element 25 is fixedly connected to the fixing member 2155, and the other end is fixedly connected to the gripping arm 2156. The sliding rod 2159 is slidably connected to the sliding hole 2158. Through the extension effect of the elastic element 2157, the distance between the gripping arms 2156 is increased to clamp photovoltaic brackets of different sizes. The restoring force of the spring continuously clamps the photovoltaic bracket. The setting of the sliding rod 2159 and the sliding hole 2158 ensures that the movement of the gripping arm 2156 is opposite.

[0038] The specific operation is as follows: For the photovoltaic bracket, the operating platform 212 is lowered, causing the bidirectional ratchet 219 to engage with ratchet 216, thus rotating the inner rotating cylinder 214. The elastic grippers 2154 of the clamping assembly 215 are used to clamp the photovoltaic components onto the rotating shaft 2151. If the photovoltaic components are to be coated, the operating platform 212 is raised, causing the bidirectional ratchet 219 to engage with ratchet 217, thus installing the photovoltaic bracket onto the clamping assembly 215.

[0039] Photovoltaic component coating: The linear drive unit 2 is activated, moving the rotating and reversing assembly 21 to create a certain distance between the photovoltaic components on the clamping assembly 215 and the sides of the frame 1. The rotary power source 218 is activated, driving the bidirectional ratchet 219 to rotate, raising the lifting platform 212. The bidirectional ratchet 219 engages with ratchet 216, causing the outer rotating cylinder 213 to rotate, and the clamping assembly 215 to rotate as well. During rotation, the guide wheel 2153 of the guide member 2152 rolls along the steering member 2140, achieving the rotation and reversal of the photovoltaic components. The coating head 32 coats both sides of the photovoltaic components. Simultaneously, the moving speed of the linear drive unit 2 and the rotation speed of the outer rotating cylinder 213 can be adjusted according to actual conditions to ensure uniform coating.

[0040] If the photovoltaic bracket needs to be coated, the lifting platform 212 is lowered, causing the bidirectional ratchet 219 to engage with the second ratchet 217. The linear drive device 2 is activated and moved to a suitable position according to the length of the photovoltaic bracket. The rotary power source 218 is activated, causing the inner rotating cylinder 214 to rotate, thus rotating the photovoltaic bracket. At this time, the linear drive device 4 is activated, causing the coating head 41 to move along the length of the photovoltaic bracket to coat it. During the coating process, the moving speed of the linear drive device 4 and the rotation speed of the inner rotating cylinder 214 can be adjusted according to the length and shape of the photovoltaic bracket to ensure coating quality.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
