[0002] In the manufacturing process of solar panels, silver paste is printed for the positive electric field and aluminum paste is printed for the negative electric field. Screen printing is used in the printing of the positive and negative electric fields of solar panels. The screen is usually made of woven stainless steel wire. In order to ensure the printing quality of solar panels during the processing and production of screen printing boards, the screen printing boards need to be inspected. Usually, the screen of solar cell screen printing boards is inspected by inspection equipment, and the existing inspection equipment is the equipment used to inspect the screen inside the solar cell screen printing board.

[0003] According to the authorized patent application No. 201120198296.4, which discloses a solar cell screen printing plate inspection device, the existing inspection device has a fixed inspection light source inside the inspection cavity when inspecting the screen of solar cell screen printing plates. When emitting light, it can only clearly inspect the screen near the light source. It is not easy to clearly inspect the screen far from the light source, resulting in uneven brightness distribution of the light source and inconvenience in moving and adjusting it, which leads to inaccurate inspection results. This affects the convenience of moving the inspection device and the accuracy of inspection of solar cell screen printing plates. Therefore, this utility model proposes a solar cell screen printing plate inspection device. Utility Model Content

[0004] The purpose of this invention is to provide a solar cell screen printing plate inspection device to solve the problems in the prior art where the inspection light source is fixed inside the inspection cavity when inspecting the screen of a solar cell screen printing plate. When emitting light, the light source can only clearly inspect the screen near the light source, and it is not easy to clearly inspect the screen far from the light source. This results in uneven distribution of the light source illumination brightness and inaccurate inspection results due to the inconvenience of moving and adjusting the light source.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solar cell screen-printed board inspection device, comprising an inspection device body, a storage groove and an inspection cavity respectively formed at both ends of the upper surface of the inspection device body, a solar cell screen-printed board body supported on the surface of the inspection cavity, a lamp holder provided at the bottom of the interior of the inspection cavity, an illumination inspection lamp tube being fitted inside the lamp holder, and the inspection device body also comprising:

[0006] A movable adjustment mechanism, comprising a movable adjustment component disposed inside the detection cavity, wherein limit control components are provided at both ends of the movable adjustment component;

[0007] A protective mechanism, comprising a winding assembly disposed at the tail end of the detection workbench, the outer surface of the winding assembly extending to the surface of the detection cavity, and sliding assemblies disposed at the connection points between the ends of the protective assembly and the sides of the detection cavity.

[0008] Preferably, the movable adjustment assembly includes a lead screw rotatably connected to the middle position of the bottom end inside the detection chamber. The end of the lead screw is equipped with a forward and reverse motor on the front surface of the detection worktable. A movable frame is provided inside the detection chamber. The structure of the lead screw and the middle position of the movable frame are matched. The bottom end of the lamp holder is fixed to the inside of the movable frame by screws.

[0009] Preferably, the limiting control component includes limiting grooves formed on both sides of the bottom end inside the detection cavity, and the end of the movable frame is provided with a limiting slider, and the limiting slider is slidably connected to the inside of the limiting groove.

[0010] Preferably, the winding assembly includes a mounting box fixed to the tail end of the inspection workbench by bolts, a winding shaft rotating inside the mounting box, a spring fitted onto the end of the winding shaft, and the two ends of the spring being fixed to the end surface of the winding shaft and the inner surface of the mounting box by screws, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a movable adjustment mechanism, the screw can be rotated by the forward and reverse motor. The rotation of the screw causes the movable frame to move within the detection cavity, positioned on the outer surface of the screw. This movement controls the movement of the movable frame, causing the lamp holder and the illumination lamp to move at the bottom of the detection cavity. When performing screen printing inspection on the lower surface of the battery screen-printed board, the lamp holder and the illumination lamp can provide close-range illumination for different positions on the lower surface of the battery screen-printed board, allowing for clear observation and reducing the likelihood of detection errors. This improves the convenience and accuracy of the movement of the detection device body for screen printing inspection of the battery screen-printed board. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a solar cell screen printing plate inspection device, including an inspection device body 100. A storage groove 102 and an inspection cavity 106 are respectively opened at both ends of the upper surface of the inspection device body 100. When in use, the inspection device body 100 stores the pre-inspected solar cell screen printing plate body 103 inside the storage groove 102. The surface of the inspection cavity 106 supports and places the solar cell screen printing plate body 103. The solar cell screen printing plate body 103 is then closed and placed on the surface of the inspection cavity 106. A lamp holder 104 is provided at the bottom of the inspection cavity 106. An illumination inspection lamp tube 105 is fitted inside the lamp holder 104. When the lamp holder 104 is energized, the illumination inspection lamp tube 105 is energized to illuminate the inside of the inspection cavity 106, allowing observation of the broken wires in the internal screen printing plate body 103. The inspection device body 100 is equipped with:

[0028] The movable adjustment mechanism includes a movable adjustment component disposed inside the detection cavity 106. Limit control components are provided at both ends of the movable adjustment component. When the detection device body 100 is used for detection, the movable adjustment mechanism can move and adjust the lamp holder 104 and the illumination detection lamp tube 105 inside the detection cavity 106 to illuminate and detect different positions on the lower surface of the battery screen printing plate body 103, so as to clearly observe the detection and reduce the likelihood of detection errors.

[0029] To facilitate the movement of the lamp holder 104 and the lighting detection lamp tube 105 within the detection cavity 106 via a movable adjustment assembly, and to enable close-range illumination detection at different positions on the lower surface of the battery screen printing plate body 103, in this embodiment, preferably, the movable adjustment assembly includes a lead screw 1042 rotatably connected to the middle position of the bottom end inside the detection cavity 106. A forward / reverse motor 1043 is mounted at the end of the lead screw 1042 on the front surface of the detection workbench 101. A movable frame 1041 is provided inside the detection cavity 106. The lead screw 1042 and the movable frame 1041 are structurally matched at their middle positions. The bottom end of the lamp holder 104 is fixed to the interior of the movable frame 1041 by screws. The forward / reverse motor 1043 can be rotated to drive the lead screw 1042 to rotate. When the lead screw 1042 rotates, it drives the movable frame 1041 to move, thereby moving the lamp holder 104 and the lighting detection lamp tube 105 to different positions on the lower surface of the battery screen printing plate body 103 for close-range illumination detection.

[0030] In order to facilitate the stable movement and adjustment of the movable frame 1041 inside the detection cavity 106 by means of the limit control component, in this embodiment, preferably, the limit control component includes limit slide grooves 1045 formed on both sides of the bottom end inside the detection cavity 106, and a limit slider 1044 is provided at the end of the movable frame 1041, and the limit slider 1044 is slidably connected to the inside of the limit slide groove 1045. When the movable frame 1041 slides inside the detection cavity 106, it can drive the limit slider 1044 to slide within the limit slide groove 1045, which facilitates the stable movement and detection of the lamp holder 104 and the lighting detection lamp tube 105 by the movable frame 1041, and allows for clear observation and detection.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8This utility model provides a technical solution: a solar cell screen printing plate inspection device, including an inspection device body 100. A storage groove 102 and an inspection cavity 106 are respectively opened at both ends of the upper surface of the inspection device body 100. When in use, the inspection device body 100 stores the pre-inspected solar cell screen printing plate body 103 inside the storage groove 102. The surface of the inspection cavity 106 supports and places the solar cell screen printing plate body 103. The solar cell screen printing plate body 103 is then closed and placed on the surface of the inspection cavity 106. A lamp holder 104 is provided at the bottom of the inspection cavity 106. An illumination inspection lamp tube 105 is fitted inside the lamp holder 104. When the lamp holder 104 is energized, the illumination inspection lamp tube 105 is energized to illuminate the inside of the inspection cavity 106, allowing observation of the broken wires in the internal screen printing plate body 103. The inspection device body 100 is also equipped with:

[0033] The protective mechanism includes a winding assembly located at the tail end of the testing workbench 101, a protective assembly whose outer surface extends to the surface of the testing cavity 106, and sliding assemblies located at the connection points between the ends of the protective assembly and the sides of the testing cavity 106. This allows the testing device body 100 to be placed after testing, with the protective mechanism protecting the surface of the testing cavity 106. This prevents dust from falling into the interior of the testing cavity 106 and onto the surface of the lighting testing lamp tube 105, thus reducing the lighting effect and improving the protective effect of the testing device body 100 on the testing cavity 106 when the battery screen printing plate body 103 is placed after screen printing testing.

[0034] To facilitate the opening or winding of the protective curtain 1064 via the winding assembly, in this embodiment, preferably, the winding assembly includes a mounting box 1061 fixed to the tail end of the detection workbench 101 by bolts. A winding shaft 1068 rotates inside the mounting box 1061. A spring 1067 is fitted onto the end of the winding shaft 1068. The two ends of the spring 1067 are respectively fixed to the end surface of the winding shaft 1068 and the inner surface of the mounting box 1061 by screws. The protective curtain 1064 can be pulled to rotate the winding shaft 1068, opening and closing the protective curtain 1064 to protect the surface of the detection chamber 106. Conversely, the deformation of the spring 1067 can rotate the winding shaft 1068 to wind up the protective curtain 1064.

[0035] To facilitate surface protection of the detection cavity 106 after use and prevent dirt and dust from entering the cavity, the protective component is preferably included in this embodiment as a protective curtain 1064 wound around the outer surface of the take-up shaft 1068. A through groove 1063 is provided at the end of the detection cavity 106, and the protective curtain 1064 passes through the through groove 1063. The protective curtain 1064 opens the surface of the detection cavity 106 through the through groove 1063, and the protective curtain 1064 protects the surface of the detection cavity 106, making it difficult for dust to fall into the cavity.

[0036] To facilitate the sliding control of opening the protective curtain 1064 via a sliding assembly, in this embodiment, preferably, the sliding assembly includes control grooves 1066 formed at the top of both sides inside the detection cavity 106. A control slider 1065 slides inside the control grooves 1066. The end of the control slider 1065 is fixed to the end of the protective curtain 1064 by screws. When the protective curtain 1064 is pulled open, the control slider 1065 can be driven to slide within the control grooves 1066 for stable opening of the protective curtain. A threaded reinforcing rod 1062 is threadedly rotated on the side of the detection workbench 101. The end of the threaded reinforcing rod 1062 presses against the surface of the control slider 1065. After the protective curtain 1064 is opened, the threaded reinforcing rod 1062 is rotated to press and fix the control slider 1065, thereby opening and fixing the protective curtain 1064.

[0037] The working principle and usage process of this utility model are as follows: During the inspection, the forward and reverse motor 1043 drives the lead screw 1042 to rotate. The rotation of the lead screw 1042 causes the moving frame 1041 to move on the outer surface of the lead screw 1042. When the moving frame 1041 moves, it drives the limiting slider 1044 to slide inside the limiting groove 1045. This movement of the moving frame 1041 causes the lamp holder 104 and the lighting detection lamp tube 105 to move at the bottom of the inspection cavity 106. When inspecting the screen printing of the lower surface of the battery screen printing plate body 103, the lamp holder 104 and the lighting detection lamp tube 105 can provide close-range illumination and inspection at different positions on the lower surface of the battery screen printing plate body 103. The inspection is clear and less prone to errors, improving the convenience and accuracy of the movement of the inspection device body 100 in inspecting the screen printing of the battery screen printing plate body 103.

[0038] Finally, when the main body 100 of the testing device is not used after testing, the end of the protective curtain 1064 is pulled directly to drive the winding shaft 1068 to rotate inside the mounting box 1061. This causes the protective curtain 1064 to fully open and close on the surface of the testing cavity 106, passing through the through groove 1063. When the protective curtain 1064 is pulled, the control slider 1065 slides within the control groove 1066 for stable opening and closing. The threaded reinforcing rod 1062 is then rotated to press against the surface of the control slider 1065 to fix the protective curtain 1064, thus protecting the surface of the testing cavity 106 after use. Furthermore, when not in use, the detection chamber 106 is not easily exposed to the outside world, preventing dust from falling inside. At the same time, the surface of the illumination detection lamp tube 105 is not easily covered by dust, reducing the illumination effect. This effectively illuminates the detection process and improves the protection effect of the detection device body 100 on the detection chamber 106 when the battery screen printing plate body 103 is placed after screen printing detection. When the detection device body 100 is in use, the threaded reinforcing rod 1062 is loosened, and the spring 1067 deforms, driving the winding shaft 1068 to rotate and roll up and close the protective curtain 1064. The end of the protective curtain 1064 is closed on one side of the through groove 1063, which does not affect the placement of the battery screen printing plate body 103 for detection.
