Technical Field
[0001] This utility model relates to the field of calibration fixture technology, specifically a calibration fixture for a cleaning rack. Background Technology
[0002] Mobile phone glass covers are an indispensable and important component of modern smartphones. They not only protect the phone screen from scratches and impacts, but also play a key role in display effects and appearance design. Cleaning is a crucial step in the production process of mobile phone glass covers. Its purpose is to remove impurities such as dust, oil, and polishing powder from the glass surface to ensure the smooth progress of subsequent processes and product quality. A cleaning rack is required for the cleaning of mobile phone glass covers.
[0003] Because the adjustment of racks of different specifications is currently quite arbitrary and there are no fixed spacing dimensions, the position of automated racks is not accurately matched, which can easily lead to scrapping. Therefore, a cleaning rack calibration fixture is proposed to solve the above-mentioned problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a cleaning rack correction fixture in view of the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cleaning rack calibration fixture, including a main board, a horizontal bar fixedly installed on the main board, a rack positioning block fixedly installed on the main board, and a slotted corresponding position opened on the main board;
[0006] The horizontal bar has an installation groove, a spacing plate is fixedly installed inside the installation groove, and a rack positioning block is fixedly installed on the horizontal bar.
[0007] Preferably, there are two horizontal bars, both of which are fixedly installed on the motherboard. The motherboard has a first mounting hole. The main function of the horizontal bars is to fix the position of the spacing plate and the motherboard. The first mounting hole allows the horizontal bars to be easily fixed to the motherboard with bolts.
[0008] Preferably, the motherboard has a second mounting hole, and there are two rack positioning blocks. The two rack positioning blocks are fixedly installed at the front right and rear right sides of the motherboard, respectively. The second mounting hole allows the frame positioning blocks to be easily fixed to the motherboard with bolts. The rack positioning blocks are used to fix the first rack and the other racks are positioned synchronously according to the spacing plate. The function of the frame positioning blocks is to use clamps to keep the position of each frame consistent.
[0009] Preferably, the crossbar has a third mounting hole, and there are two corresponding slots. The two corresponding slots are respectively located on the left and right sides of the front of the main board. The third mounting hole allows the spacing plate to be easily fixed to the crossbar with bolts. The function of the corresponding slot is to keep the slot direction consistent with that of the frame.
[0010] Preferably, the crossbar has a fourth mounting hole, and there are three spacing plates. The three spacing plates are fixedly installed on the crossbar at equal intervals. The fourth mounting hole allows the rack positioning block to be easily fixed to the crossbar with bolts. The spacing plates can be replaced according to the product width when changing product models.
[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0012] This cleaning rack calibration fixture matches the cleaning rack via a main board. One of its outer long sides has two slots that correspond to the two opening slots on the cleaning rack for orientation confirmation. The central area is hollowed out for visually adjusting the spacing. A horizontal bar is used to fix the spacing plate position. The spacing plate can be increased in size according to different product widths to ensure sufficient clearance during rack adjustment so that the product is neither too tight nor too loose when inserted into the rack. Only the spacing plate needs to be replaced for each model change; the rest of the structure remains unchanged. A rack positioning block positions the first rack to ensure uniform orientation. A rack alignment block keeps the fixture aligned with the rack, solving the problem of inconsistent rack positions, preventing product scrap due to automated rack insertion, reducing production costs, and preventing scratches caused by product stacking and rack collapse due to loose rack adjustment. This improves product yield and reduces production costs. Attached Figure Description
