[0002] Light-emitting diodes (LEDs) are semiconductor electronic components that convert electrical energy into light energy. Currently, LEDs are widely used in indoor and outdoor LED lighting, LED displays, traffic lights, automotive lights, display backlights, lighting fixtures, fiber optic communications, and more.

[0003] LED lighting fixtures typically use LED chips mounted on an LED board as the light-emitting device. After the LED board is manufactured, its outer surface needs to be treated, specifically by encapsulating a transparent coating around its perimeter. This coating serves as insulation. Currently, this surface treatment is usually done manually, where a liquid coating is applied to the outer perimeter of the LED board to form the coating. However, this manual surface treatment method is inefficient, thus affecting the production efficiency of LED lighting fixtures.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0048] Based on the foregoing, existing LED lighting fixtures typically use LED chips mounted on an LED board as the light-emitting device. After the LED board is manufactured, its outer surface needs to be treated, specifically by encapsulating a transparent coating around its perimeter. This coating serves as insulation. Currently, this surface treatment is usually done manually, where a liquid coating is applied to the outer perimeter of the LED board to form the coating. However, this manual surface treatment method is inefficient, thus affecting the production efficiency of LED lighting fixtures.

[0049] To resolve the above issues, please refer to [link / reference]. Figures 1 to 13This embodiment provides a surface treatment device for LED light panels. The device includes a feeding device 210, a cleaning device 220, a surface treatment device 230, and a detection device 240. The feeding device 210 includes a first conveyor line 211 and a first transfer mechanism 212. The first conveyor line 211 can transport a carrier plate 100 carrying an LED light panel 101 from a first feeding station to a first unloading station. The first transfer mechanism 212 includes a first suction nozzle 2121, which can pick up the LED light panel 101 at the first unloading station. The first suction nozzle 2121 can move from the first unloading station to the cleaning device 220, which can clean the LED light panel 101 picked up by the first suction nozzle 2121. The surface treatment device 230 includes a liquid tank 231, a heater 232, a clamping module 233, a first driving member 234, a second driving member 235, and a third driving member 236. The liquid tank 231 contains a liquid, and the heater 232 is configured to heat the liquid in the liquid tank 231. The gripping module 233 includes a mounting shaft 2331 and a gripper 2332, with the gripper 2332 fixedly connected to the mounting shaft 2331. A first drive member 234 can drive the gripping module 233 to move between the liquid tank 231 and the cleaning device 220. A second drive member 235 can drive the gripping module 233 to move vertically up and down. A third drive member 236 can drive the mounting shaft 2331 to rotate around... Its axis rotates, enabling the gripper 2332 to have a first working position with its opening facing upward. The gripper 2332 in the first working position can hold the LED light board 101 sucked by the first suction nozzle 2121. The detection device 240 includes a second transfer mechanism 241 and a detection mechanism 242. The second transfer mechanism 241 can transfer the LED light board 101 from the gripper 2332 to the detection mechanism 242. The detection mechanism 242 can detect the insulation performance of the LED light board 101.

[0050] In this embodiment, the first suction nozzle 2121 of the feeding device 210 can transport the LED light panel 101 to the cleaning device 220. The cleaning device 220 can clean the dust on the surface of the LED light panel 101. The gripper 2332 of the surface treatment device 230 can grip the LED light panel 101 on the first suction nozzle 2121 and transport the LED light panel 101 to the liquid tank 231. The LED light panel 101 held by the gripper 2332 can be immersed in the liquid contained in the liquid tank 231 to coat the outer periphery of the LED light panel 101 with a layer of liquid, thereby forming a coating on the outer periphery of the LED light panel 101. The second transfer mechanism 241 can transfer the LED light panel 101 from the gripper 2332 to the detection mechanism 242. The detection mechanism 242 can detect the insulation performance of the LED light panel 101. Based on the above, the surface treatment equipment for LED light boards in this embodiment uses a mechanical structure to replace manual labor in surface treatment of LED light boards 101, thereby improving work efficiency and avoiding affecting the production efficiency of LED lamps.

[0051] Specifically, in this embodiment, the carrier plate 100 is elongated. The first conveyor line 211 includes two first side plates 2111 arranged opposite to each other. A conveyor belt 2112 is arranged between the two first side plates 2111. The extension direction of the conveyor belt 2112 is parallel to the extension direction of the first side plates 2111. The first loading station and the first unloading station are located on both sides of the conveyor belt 2112 along its extension direction. The carrier plate 100 carrying the LED light panel 101 can be placed on the conveyor belt 2112. The conveyor belt 2112 can transport the carrier plate 100 carrying the LED light panel 101 from the first loading station to the first unloading station. The two first side plates 2111 can provide guidance for the carrier plate 100. The surface treatment equipment for LED light panels also includes a workbench 260, and the feeding device 210 includes a first mounting frame 213 and a second mounting frame 214. The first mounting frame 213 is mounted on the workbench 260, and two first side plates 2111 are fixedly connected to the first mounting frame 213. A tenth driving member 2131 is mounted on the first mounting frame 213, which drives the second mounting frame 214 to move along the extension direction of the conveyor belt 2112. An eleventh driving member 2141 is mounted on the second mounting frame 214, and a pressure plate 2142 is connected to the movable end of the eleventh driving member 2141. The pressure plate 2142 has locking posts 21421 on both sides along the extension direction of the conveyor belt 2112. The eleventh driving component 2141 can drive the pressure plate 2142 to rise and fall vertically. Both ends of the carrier plate 100 are provided with locking holes 102. When the carrier plate 100 carrying the LED light board 101 is located at the first unloading station, the tenth driving component 2131 drives the first mounting bracket 213 to move along the extension direction of the conveyor belt 2112 so that the two locking posts 21421 on the pressure plate 2142 correspond one-to-one with the locking holes 102 at both ends of the carrier plate 100 and are located directly above the two locking holes 102 respectively. The tenth driving component 2131 drives the pressure plate 2142 to fall vertically so that the two locking posts 21421 extend into the two locking holes 102 one-to-one, thereby fixing the carrier plate 100 to the first unloading station.

[0052] When the carrier plate 100 carrying the LED light board 101 is fixed to the first unloading station, the first suction nozzle 2121 can pick up the LED light board 101 carried on the carrier plate 100 and transfer the LED light board 101 to the cleaning device 220 to clean the LED light board 101, so as to prevent the insulation performance of the coating formed on its outer periphery from being affected by dust.

[0053] After the cleaning device 220 completes cleaning, the first driving member 234 drives the gripper 2332 to move to the cleaning device 220, and the third driving member 236 drives the mounting shaft 2331 to rotate, thereby placing the gripper 2332 in the first working position. Simultaneously, the second driving member 235 drives the gripper 2332 to descend vertically, positioning it directly below the first suction nozzle 2121. Because the gripper 2332 is in the first working position, when the two gripping arms of the gripper 2332 open and the second driving member 235 drives the gripper 2332... After rising vertically, the LED light panel 101 can be accommodated between the two gripping arms. At this time, the two gripping arms of the gripper 2332 close, thereby achieving the gripping of the LED light panel 101. After the gripper 2332 grips the LED light panel 101, the first suction nozzle 2121 stops adsorbing the LED light panel 101, and the first driving member 234 drives the gripper 2332 back to the liquid tank 231. It can be understood that, in addition to having a first working position with the opening facing upward, the gripper 2332 also has a second working position with the opening facing downward. When the gripper 2332 returns to the liquid tank... After position 231, the third driving member 236 drives the mounting shaft 2331 to rotate, so that the gripper 2332 is in the second working position. The second driving member 235 drives the gripper 2332 to descend, so that the LED light panel 101 held by the gripper 2332 is immersed in the liquid. After the LED light panel 101 is immersed in the liquid, the third driving member 236 drives the mounting shaft 2331 to rotate, so that the gripper 2332 swings between the first working position and the second working position, thereby ensuring that the outer periphery of the LED light panel 101 is fully covered with the liquid. After that, the second driving member 236 drives the mounting shaft 2331 to rotate, so that the gripper 2332 swings between the first working position and the second working position, thereby ensuring that the outer periphery of the LED light panel 101 is fully covered with the liquid. 35 drives the gripper 2332 to rise, so as to extract the LED light board 101 held by the gripper 2332 from the liquid. After the LED light board 101 is extracted from the liquid, the gripper 2332 is placed above the liquid tank 231 for a period of time to allow the liquid surrounding the LED light board 101 to solidify, thereby forming an insulating coating on the outer periphery of the LED light board 101. Then, the second transfer mechanism 241 transfers the LED light board 101 from the gripper 2332 to the detection mechanism 242, and the detection mechanism 242 tests the insulation performance of the LED light board 101.

[0054] It is understandable that the liquid in the liquid tank 231 may solidify after being left to stand for a long time. If the liquid in the liquid tank 231 solidifies, it will be impossible to wrap the liquid around the LED light board 101 held by the gripper 2332. Therefore, in this embodiment, a heater 232 is provided. The heater 232 can heat the liquid in the liquid tank 231 to prevent the liquid in the liquid tank 231 from solidifying.

[0055] Based on the above, the surface treatment equipment for LED light boards in this embodiment uses a mechanical structure to replace manual labor in surface treatment of LED light boards 101, thereby improving work efficiency and avoiding affecting the production efficiency of LED lamps.

[0056] In this embodiment, the gripper 2332 can be a pneumatic gripper 2332 or an electric gripper 2332, etc., and no specific limitation is made in this embodiment.

[0057] It is understood that the surface treatment device 230 also includes a third mounting bracket 238 and a fourth mounting bracket 239. The third mounting bracket 238 is mounted on the worktable 260, and the fourth mounting bracket 239 is slidably connected to the third mounting bracket 238. The clamping module 233 is connected to the fourth mounting bracket 239. The first driving member 234 mentioned above can be a servo motor or a stepper motor, etc., and the movable end of the first driving member 234 is connected to the first transmission belt 2341. The fourth mounting bracket 239 is fixedly connected to the first transmission belt 2341, thereby driving the clamping module 233 to move between the liquid tank 231 and the cleaning device 220. The second driving member 23... 5 can be a servo motor or a stepper motor, etc., and the movable end of the second drive member 235 is connected to the first lead screw via the second transmission belt 2351. The clamping module 233 also includes a fifth mounting bracket 2333, and the mounting shaft 2331 is rotatably connected to the fifth mounting bracket 2333. The fifth mounting bracket 2333 is screwed onto the first lead screw (not shown in the figure). The second drive member 235 can drive the first lead screw to rotate, thereby causing the fifth mounting bracket 2333 to rise and fall vertically. The third drive member 236 is mounted on the fifth mounting bracket 2333. The third drive member 236 can be a servo motor or a stepper motor, etc., and this embodiment does not impose specific limitations on it. The tenth drive member 2131 is a KK module, and the eleventh drive member 2141 can be a linear drive structure such as a cylinder or an electric cylinder.

[0058] It should be noted that in this embodiment, there are multiple first suction nozzles 2121 and multiple grippers 2332. The multiple first suction nozzles 2121 and multiple grippers 2332 are arranged in a one-to-one correspondence. The multiple grippers 2332 are fixedly connected to the mounting shaft 2331 and are arranged at intervals along the extension direction of the mounting shaft 2331 so as to perform surface treatment on multiple LED light panels 101 at one time.

[0059] Preferably, the cleaning device 220 in this embodiment includes two cleaning shafts 221, which are arranged in parallel. Each of the two cleaning shafts 221 is fitted with a brush (not shown in the figure) around its outer periphery. The two cleaning shafts 221 can rotate around their respective axes. The LED light panel 101 sucked by the first suction nozzle 2121 can be moved between the two cleaning shafts 221. Specifically, the first suction nozzle 2121 can be moved above the two cleaning shafts 221 and can be raised and lowered in the vertical direction so that the LED light panel 101 can be moved between the two cleaning shafts 221. When the LED light panel 101 is located between the two cleaning shafts 221, the brush fitted on the outer periphery of the cleaning shaft 221 can sweep across the LED light panel 101 to clean it when the cleaning shaft 221 rotates.

[0060] In addition to the first suction nozzle 2121, the first transfer mechanism 212 in this embodiment also includes a fourth driving member 2122 and a fifth driving member (not shown in the figure). The fourth driving member 2122 can drive the first suction nozzle 2121 to move above the two cleaning shafts 221 or above the first unloading station. Specifically, the first suction nozzle 2121 is mounted on the sixth mounting bracket 2124, which is slidably connected to the first mounting bracket 213. The fourth driving member 2122 can be a stepper motor or a servo motor, etc. The movable end of the fourth driving member 2122 is connected to a third transmission belt 21221, and the sixth mounting bracket 2124 is fixedly connected to the third transmission belt 21221. 122 drives the sixth mounting frame 2124 to move horizontally above the two cleaning shafts 221 or above the first unloading station via the third transmission belt 21221. The fifth driving component can drive the first suction nozzle 2121 to rise and fall vertically. Specifically, the first suction nozzle 2121 is slidably connected to the sixth mounting frame 2124 in the vertical direction. The fifth driving component can be a stepper motor or a servo motor, etc. The movable end of the fifth driving component is connected to the fourth transmission belt 21231. The first suction nozzle 2121 is fixedly connected to the fourth transmission belt 21231. The fifth driving component drives the first suction nozzle 2121 to rise and fall via the fourth transmission belt 21231. The structure of the first transfer mechanism 212 in this embodiment is simple.

[0061] Preferably, the surface treatment device 230 in this embodiment further includes a deflector 2371, a sixth driving member 2372, and a seventh driving member (not shown in the figure). The deflector 2371 includes a connecting portion 23711 and a deflecting portion 23712. The connecting portion 23711 is fixedly connected to the movable end of the sixth driving member 2372. The deflecting portion 23712 is located at the end of the connecting portion 23711 away from the sixth driving member 2372 and is directly opposite the opening of the liquid tank 231. The sixth driving member 2372 can drive the deflector 2371 to move up and down in the vertical direction and can extend the deflecting portion 23712 into the liquid. The seventh driving member can drive the sixth driving member. 2372 moves along the length of the liquid tank 231, thereby enabling the agitator 23712 to agitate the liquid in the liquid tank 231 to prevent sedimentation. The sixth drive member 2372 can be a linear drive structure such as a cylinder or an electric cylinder. In this embodiment, there is no specific limitation. The seventh drive member can be a stepper motor or a servo motor. The movable end of the seventh drive member is connected to the fifth transmission belt 23731. The sixth drive member 2372 is fixedly connected to the fifth transmission belt 23731. The seventh drive member can drive the sixth drive member 2372 to move along the length of the liquid tank 231 through the fifth transmission belt 23731.

[0062] Before the second drive member 235 drives the gripper 2332 to descend so that the LED light panel 101 held by the gripper 2332 is immersed in the liquid, the seventh drive member drives the sixth drive member 2372 to move to the leftmost or rightmost position of the liquid tank 231 along its extension direction so that the paddle plate 2371 can avoid the gripper 2332, thereby ensuring that the LED light panel 101 held by the gripper 2332 can be immersed in the liquid.

[0063] Furthermore, the second transfer mechanism 241 includes a first transport module 2411, a temporary storage module 2412, and a second transport module 2413. The first transport module 2411 includes a second suction nozzle 24111, which can pick up the LED light board 101 held by the gripper 2332. The temporary storage module 2412 is provided with a second carrier plate. The second suction nozzle 24111 can move to the temporary storage module 2412 and place the LED light board 101 in the carrier groove of the second carrier plate of the temporary storage module 2412. The second transport module 2413 includes a third suction nozzle 24131, which can pick up the LED light board 101 carried on the second carrier plate of the temporary storage module 2412 and can move to the detection mechanism 242. The temporary storage mechanism can store the LED light board 101 that is to be detected when the third suction nozzle 24131 transfers the LED light board 101 to the detection mechanism 242 for detection.

[0064] The first transport module 2411 further includes a twelfth driving component 24112, which is a KK module. The twelfth driving component 24112 drives the second suction nozzle 24111 to move to the temporary storage module 2412. Specifically, after the liquid material surrounding the LED light panel 101 solidifies, the first driving component 234 drives the clamping module 233 to move from the liquid tank 231 to the first transport module 2411. When the clamping module 233 moves from the liquid tank 231 to the first transport module 2411, the gripper 2332 is located below the second suction nozzle 24111. The third driving component 236 drives the mounting shaft 2331 to rotate, thereby causing the clamp... When the claw 2332 is in the first working position, the second driving member 235 drives the claw 2332 to rise vertically so that the second suction nozzle 24111 can contact the LED light panel 101 held by the claw 2332, thereby enabling the second suction nozzle 24111 to pick up the LED light panel 101 held by the claw 2332. After the second suction nozzle 24111 picks up the LED light panel 101 held by the claw 2332, the claw 2332 releases the LED light panel 101. Then, the first driving member 234 drives the clamping module 233 to return to the liquid tank 231, while the twelfth driving member 24112 drives the second suction nozzle 24111 to move to the temporary storage module 2412.

[0065] It is understandable that there are multiple second suction nozzles 24111 and third suction nozzles 24131, and the number of first suction nozzles 2121, grippers 2332, second suction nozzles 24111 and third suction nozzles 24131 are equal.

[0066] Preferably, the temporary storage module 2412 includes two drive shafts 24121 arranged opposite to each other, a drive chain 24122 wound between the two drive shafts 24121, and a plurality of second carrier plates fixedly connected to the drive chain 24122. The plurality of second carrier plates are spaced apart along the arrangement direction of the two drive shafts 24121. The drive chain 24122 is provided with a second loading station and a second unloading station along its conveying direction. A second suction nozzle 24111 can move to the second loading station, and a third suction nozzle 24131 can move to the second unloading station and is fixedly connected to the drive chain 24122. The second carrier plate can be moved sequentially to the second loading station and the second unloading station. That is, the empty second carrier plate can first move to the second loading station, and the LED light board 101 picked up by the second suction nozzle 24111 can be placed on the second carrier plate located at the second loading station. The second carrier plate carrying the LED light board 101 can be moved from the second loading station to the second unloading station. The third suction nozzle 24131 can pick up the LED light board 101 from the second carrier plate located at the second unloading station. After that, the empty second carrier plate can return to the second loading station from the second unloading station.

[0067] Specifically, in addition to the twelfth driving member 24112, the first conveying module 2411 also includes a thirteenth driving member 24113. The thirteenth driving member 24113 can be a linear drive structure such as a cylinder or an electric cylinder. The second suction nozzle 24111 is connected to the movable end of the thirteenth driving member 24113. The thirteenth driving member 24113 is connected to the twelfth driving member 24112 in a transmission manner. That is, the twelfth driving member 24112 can drive the thirteenth driving member 24113 to move to the second loading station. The thirteenth driving member 24113 can drive the second suction nozzle 24111 to rise and fall in the vertical direction to place the LED light board 101 onto the carrier plate 100 located at the second loading station.

[0068] In addition to the third suction nozzle 24131, the second transport module 2413 also includes a seventh mounting bracket 24132, a fourteenth drive component 24133, a fifteenth drive component 24134, and a sixteenth drive component 24135. The seventh mounting bracket 24132 is mounted on the workbench 260, and the fourteenth drive component 24133 is mounted on the seventh mounting bracket 24132. The movable end of the fourteenth drive component 24133 is connected to a first connecting plate 24136, and the fourteenth drive component 24133 can drive the first connecting plate 24135. The connecting plate 24136 moves horizontally between the second unloading station and the inspection mechanism 242. A second connecting plate 24137 is slidably connected to the first connecting plate 24136 in the vertical direction. A fifteenth driving component 24134 is mounted on the first connecting plate 24136 and is used to drive the second connecting plate 24137 to move vertically. A third connecting plate 24138 is slidably connected to the second connecting plate 24137 in a horizontal direction perpendicular to the moving direction of the first connecting plate 24136. A sixteenth driving component... The actuator 24135 is mounted on the second connecting plate 24137 and is used to drive the third connecting plate 24138 to move in a horizontal direction perpendicular to the moving direction of the first connecting plate 24136. The third suction nozzle 24131 is fixedly connected to the third connecting plate 24138. In this embodiment, the fourteenth driving member 24133 and the sixteenth driving member 24135 can drive the third suction nozzle 24131 to move in the horizontal plane, thereby ensuring that the third suction nozzle 24131 can communicate with the second material unloading station located at the second unloading station. The LED light panel 101 on the carrier plate is facing each other. The fifteenth driving member 24134 can drive the third suction nozzle 24131 to rise and fall in the vertical direction so that the third suction nozzle 24131 can pick up the LED light panel 101. That is, in this embodiment, the three-axis movement of the third suction nozzle 24131 is realized by the fourteenth driving member 24133, the fifteenth driving member 24134 and the sixteenth driving member 24135 to ensure that the third suction nozzle 24131 can accurately pick up the LED light panel 101 from the second unloading station.

[0069] Preferably, the spacing between any two adjacent carrier plates 100 on the transmission chain 24122 is equal. The temporary storage module 2412 further includes a circular plate 24123 and rollers 24124. The circular plate 24123 is fixedly connected to one of the two transmission shafts 24121, and the axis of the circular plate 24123 coincides with the axis of the transmission shaft 24121. At least two limiting grooves 241231 are formed on the edge of the circular plate 24123. The at least two limiting grooves 241231 are evenly arranged along the circumference of the circular plate 24123. When the carrier plate 100 fixedly connected to the transmission chain 24122 is... When the plate 100 moves to the second loading station or the second unloading station, the roller 24124 is directly opposite one of the at least two limiting grooves 241231. The roller 24124 can move into the limiting groove 241231, and the wheel surface of the roller 24124 can fit against the groove wall of the limiting groove 241231, that is, the roller 24124 can be engaged in the limiting groove 241231 to fix the second carrier plate to the second loading station or the second unloading station. Moreover, in this embodiment, at least two limiting grooves 241231 can be directly opposite the roller 24124 in sequence. When the circular plate 24123 rotates from one of the two adjacent limiting grooves 241231 facing the roller 24124 to the other facing the roller 24124, the moving distance of the transmission chain 24122 is equal to the distance between the two adjacent second carrier plates. That is, when the roller 24124 is facing at least one of the two limiting grooves 241231, there must be two carrier plates 100 located at the second loading station and the second unloading station respectively. At this time, the roller 24124 moves into the limiting groove 241231, thereby enabling it to move between the second loading station and the second unloading station. A second carrier plate is fixed at each of the two locations, which facilitates the second suction nozzle 24111 to place the LED light board 101 onto the second carrier plate located at the second loading station, and also facilitates the third suction nozzle 24131 to pick up the LED light board 101 from the second carrier plate located at the second unloading station. After the transmission chain 24122 moves a distance equal to the distance between two adjacent second carrier plates, an empty second carrier plate is fixed at the second loading station, and at the same time, a second carrier plate carrying the LED light board 101 is fixed at the second unloading station.

The second limiting plate 24126 can abut against the downstream side of the first limiting plate 24125 in the transmission direction of the transmission chain 24122. When the roller 24124 moves into the limiting groove 241231, the eighth driving member 24127 drives the second limiting plate 24126 to move up and down in the vertical direction to further limit the second carrier plate located at the second loading station and the second unloading station.

[0071] It is understood that the eighth drive component 24127 can be selected as a linear drive structure such as a cylinder or an electric cylinder, and no specific restrictions are made on this in this embodiment.

[0072] Furthermore, the testing mechanism 242 includes a platform 2421, a first push plate 2422, a ninth driving member 2423, and a testing plate 2424. The platform 2421 is mounted on the workbench 260 and carries an unloaded third plate. A first guide plate 24211 and a second guide plate 24212 are arranged opposite to each other on the platform 2421. The two ends of the third plate abut against the first guide plate 24211 and the second guide plate 24212, respectively. A third loading station and a third unloading station are respectively arranged on both sides of the first guide plate 24211 along its extension direction. The ninth driving member 2423 can drive the first push plate 2422 to move along the extension direction of the first guide plate 24211. 2422 can push the third carrier plate from the third loading station to the third unloading station. The second transfer mechanism 241 can transfer the LED light board 101 from the gripper 2332 to the third carrier plate located at the third loading station. The detection plate 2424 is provided with contacts. The detection plate 2424 is located at the third unloading station and can be raised and lowered in the vertical direction. Specifically, the detection mechanism 242 also includes a seventeenth driving member 2425. The seventeenth driving member 2425 can drive the detection plate 2424 to rise and lower in the vertical direction. The contacts can contact the LED light board 101 on the third carrier plate located at the third unloading station. When the contacts contact the LED light board 101, the insulation performance of the LED light board 101 is detected.

[0073] In this embodiment, the ninth driving component 2423 and the seventeenth driving component 2425 can both be selected as linear drive structures such as cylinders or electric cylinders, and no specific restrictions are imposed on them.

[0074] It is understood that the principle of detecting insulation performance through contact is existing technology, therefore, it will not be described in detail in this embodiment.

[0075] It should be noted that the testing mechanism 242 also includes a third conveyor line 2426, which is used to supply an empty third carrier plate to the third loading station. The structure of the third conveyor line 2426 is the same as that of the first conveyor line 211. The structure of the third conveyor line 2426 will not be described in detail in this embodiment.

[0076] Preferably, the surface treatment equipment for LED light panels further includes a feeding device 250.
