Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic junction box processing technology, specifically to a tooling for detecting the marking position of photovoltaic junction boxes. Background Technology
[0002] A photovoltaic junction box is a connection device between a solar cell array composed of solar cell modules and a solar charging control device. Its main function is to connect and protect the solar photovoltaic modules.
[0003] During the production and processing of photovoltaic junction boxes, parameter markings need to be processed on the box body by etching or labeling. In order to ensure that the processing standards of photovoltaic junction boxes are uniform, the marking position of the markings needs to be checked after the parameter markings are processed to ensure that the marking position of each photovoltaic junction box is uniform.
[0004] Currently, the accuracy of the marking position on photovoltaic junction boxes is mainly determined by scanning the boxes with a visual lens. However, this method requires the construction of a visual lens inspection platform to convert, analyze, and process the information captured by the lens. Therefore, the overall debugging work is quite cumbersome and costly. Furthermore, the parameter markings on the photovoltaic junction boxes are only used to display the parameters of the junction boxes themselves, so the positional accuracy of the markings is not overly critical. In conclusion, the method of determining the marking position by a visual lens does not meet the needs of actual production. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tooling for detecting the marking position on photovoltaic junction boxes, which can ensure rapid detection of the marking position on photovoltaic junction boxes while reducing the overall detection cost.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for detecting the marking position of a photovoltaic junction box, comprising a workbench, a placement plate on the workbench for placing the photovoltaic junction box to be tested, a liftable mounting plate above the workbench, a through observation port on the mounting plate, a horizontally movable positioning block on the mounting plate, one end of the positioning block extending to a position opposite to the observation port as a positioning part, a positioning opening on the positioning part, and a contact part perpendicular to the positioning block on the positioning block. The positioning block is lifted and lowered by the mounting plate to make the contact part contact the photovoltaic junction box, thereby determining whether the parameter marking on the photovoltaic junction box is opposite to the positioning opening.
[0007] The present invention is further configured such that: a horizontally arranged slide rail is fixed on the mounting plate, a slider is coupled on the slide rail, the slider can form a sliding fit with the slide rail, and the positioning block is fixed to the slider.
[0008] The present invention is further configured such that: the coupling point between the slider and the slide rail is a coupling surface, the coupling surface is provided with a mounting groove with the opening facing the slide rail, the mounting groove is provided with a pressure block and a pressure spring, one end of the pressure spring is fixed to the bottom of the mounting groove and the other end is fixed to the pressure block, the pressure spring is used to apply pressure to the pressure block, and the slider is provided with a connecting rod, the connecting rod drives the pressure blocks on both sides away from the slide rail by rotating.
[0009] The present invention is further configured such that: the slider is provided with a threaded hole, the connecting rod can form a threaded engagement with the threaded hole, a cavity communicating with the threaded hole is provided below the threaded hole, the pressure block is provided with a transmission part extending to the cavity, the end of the connecting rod is provided with a pushing inclined surface, and the transmission part is provided with a coupling inclined surface that facilitates full contact with the pushing inclined surface.
[0010] The present invention is further configured such that: a protruding boss is fixed on the workbench, and a connecting waist hole is provided on the boss; the placement plate is fixed to the connecting waist hole by a locking member.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for 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. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] like Figures 1 to 4 As shown, this utility model discloses a coding position detection fixture for photovoltaic junction boxes, including a workbench 1, a placement plate 2 on the workbench 1, the placement plate 2 is used to place the photovoltaic junction box 100 to be tested, specifically, the placement plate 2 is provided with a placement groove 21, one side of the placement groove 21 is an open structure, so that the photovoltaic junction box 100 to be tested can slide into the placement groove 21 through the open structure.
[0021] A liftable mounting plate 3 is provided above the workbench 1. Specifically, a sleeve 32 is provided on the side of the mounting plate 3 facing away from the slide rail 5. The sleeve 32 is integrally set with the mounting plate 3. A guide rod 11 is fixed on the workbench 1. The sleeve 32 is fitted around the outer periphery of the guide rod 11. A return spring 12 is fitted around the outer periphery of the guide rod 11. One end of the return spring 12 is fixed to the workbench 1, and the other end is fixed to the sleeve 32. When the mounting plate 3 is pressed downward, it can slide downward along the guide rod 11 through the sleeve 32. After the mounting plate 3 is released, the return spring 12, which was compressed when sliding downward, can drive the mounting plate 3 to return to its original position. In this way, the lifting and lowering of the mounting plate 3 can be realized.
[0022] In addition, the mounting plate 3 has a through observation port 31, and the mounting plate 3 has a horizontally movable positioning block 4. One end of the positioning block 4 extends to a position opposite to the observation port 31 as a positioning part 41. The positioning part 41 has a positioning opening 411, and the positioning block 4 has a contact part 42 perpendicular to the positioning block 4. The positioning block 4 is lifted and lowered by the mounting plate 3 so that the contact part 42 contacts the photovoltaic junction box 100. The positioning block 4 can be positioned by the contact part 42 contacting the photovoltaic junction box 100. The principle of ensuring that the positioning block 4 is in place is that in the existing photovoltaic junction box 100, its outer wall is often provided with a locking block 200 for installing the cover. Thus, by making the contact part 42 contact the locking block 200, the positioning can be achieved. Block 4 is used for rapid positioning. Therefore, when it is necessary to detect the opening position of the parameter markings on the photovoltaic junction box 100, it is only necessary to lower the mounting plate 3 to drive the positioning block 4 to descend, so that the contact part 42 contacts the photovoltaic junction box 100 for positioning. Then, it can be observed through the observation port 31 on the mounting plate 3 whether the parameter markings on the photovoltaic junction box 100 have fallen into the positioning port 411, so as to determine whether the opening position of the parameter markings is correct. Compared with the existing technology of detecting through a vision lens, there is no need to build a vision lens detection platform, which can effectively reduce the difficulty of overall debugging. Furthermore, the detection method that can be performed with a simple mechanical structure can also reduce the overall detection cost.
[0023] In this embodiment, the positioning block 4 can move horizontally on the mounting plate 3. A horizontally arranged slide rail 5 is fixed on the mounting plate 3, and a slider 6 is coupled on the slide rail 5. The slider 6 can form a sliding fit with the slide rail 5, and the positioning block 4 is fixed to the slider 6 by bolts and nuts. Thus, by pushing the slider 6, the positioning block 4 can move along the slider 6. In this way, the position of the positioning block 4 can be adjusted so that when testing photovoltaic junction boxes 100 of different specifications, the position of the positioning block 4 can be adjusted to adapt to photovoltaic junction boxes 100 of different specifications.
[0024] In addition, the coupling point between the slider 6 and the slide rail 5 is used as the coupling surface. The coupling surface is provided with a mounting groove 61 with the opening facing the slide rail 5. The mounting groove 61 is provided with a pressure block 7 and a pressure spring 8. One end of the pressure spring 8 is fixed to the bottom of the mounting groove 61 and the other end is fixed to the pressure block 7. The pressure spring 8 is used to apply pressure to the pressure block 7. In this way, after the slider 6 is coupled to the slide rail 5, the positive pressure applied by the pressure block 7 can increase the friction between the slider 6 and the slide rail 5, thereby preventing the slider 6 from moving erroneously on the slide rail 5.
[0025] Furthermore, when the slider 6 needs to slide, a connecting rod 9 is provided on the slider 6. The slider 6 has a threaded hole that can form a threaded fit with the connecting rod 9. By rotating the connecting rod 9, the connecting rod 9 can be raised and lowered. During the descent, the pushing inclined surface 91 at the end of the connecting rod 9 can fully contact the coupling inclined surface 711 on the transmission part 71, thereby pushing the transmission parts 71 on both sides to move in opposite directions in the chamber 62. This can drive the pressure block 7 away from the slide rail 5, thereby releasing the slide rail 5. At this time, the slider 6 can slide normally.
[0026] In this embodiment, a protruding boss 10 is further fixed on the workbench 1. The boss 10 is provided with a connecting waist hole 101. The placement plate 2 is fixed to the connecting waist hole 101 by a locking member. The setting of the boss 10 can increase the installation height of the placement plate 2. In this way, when observing whether the parameter marker of the photovoltaic detection box in the placement slot 21 is opposite to the detection port through the observation port 31, the user's bending distance can be reduced, thereby improving the convenience of observation. In addition, the setting of the connecting waist hole 101 can adjust the installation position of the placement plate 2. The moving adjustment direction of the placement plate 2 is perpendicular to the horizontal moving direction of the positioning block 4 on the same plane. This can accommodate more specifications of photovoltaic junction boxes 100 and further expand the scope of use.
[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
