[0039] This embodiment provides a PCB squeegee storage rack, including a rack body 1 and a storage device 2 provided on the rack body 1. The storage device 2 includes:

[0040] A placement tray 21, provided on the rack body 1;

[0041] A plurality of storage slots 22, which are arranged at intervals along the Y direction on the placement tray 21;

[0042] A clamping mechanism 23, provided above the storage slot 22. The clamping mechanism 23 includes two clamping blocks 231 and an elastic member 232;

[0043] A squeegee 24, which is inserted into the storage slot 22;

[0044] Among them, the two clamping blocks 231 are arranged on both sides of the squeegee 24. The clamping blocks 231 are inserted into the storage slot 22 and are slidably connected to the storage slot 22. The elastic member 232 is arranged at one end of the clamping block 231 away from the squeegee 24. The elastic member 232 is arranged in the storage slot 22. One end of the elastic member 232 abuts against the inner wall of the storage slot 22, and the other end abuts against the clamping block 231.

[0045] Such as Figure 1-7As shown in the figure, two clamping blocks 231 are inserted into the storage slot 22. The clamping blocks 231 can move freely along the X direction in the storage slot 22. When storing the scraper 24, first move the two clamping blocks 231 to both ends of the storage slot 22 in the X direction. After inserting the scraper 24, the elastic member 232 provided on the side of the clamping block 231 away from the scraper 24 generates an elastic force on the clamping block 231, pushing the clamping block 231 to abut against both sides of the scraper 24, thereby playing a role in clamping and fixing the scraper 24. The cooperation of the two clamping blocks 231 and the elastic member 232 can adjust the fixing size according to the scraper 24 of different specifications and sizes, so as to clamp and fix the scraper 24 of any size. At the same time, the fixing is stable, making the scraper 24 not easy to shake and be damaged during storage, and improving the storage safety of the scraper 24.

[0046] The frame body 1 is cylindrical. The frame body 1 penetrates through the placing plate 21 and is fixedly connected to the placing plate 21 by clamping. A plurality of placing plates 21 are arranged along the height direction of the frame body 1, which can increase the storage quantity of the scraper 24 and enhance the storage capacity of the storage rack.

[0047] The clamping block 231 can be made of materials such as stainless steel. In this utility model, it is preferably made of plastic. The plastic is light in weight and is easily pushed by the elastic member 232 to clamp and fix the scraper 24. It also has good wear resistance and low cost, which can reduce the maintenance cost while improving the fixing effect.

[0048] The clamping mechanism 23 further includes:

[0049] Two connecting rods 233, which are arranged on both sides of the clamping block 231 in the Y direction. The connecting rods 233 are hinged to the clamping block 231;

[0050] A fixing block 234, which is arranged between the two connecting rods 233. The fixing block 234 is arranged above the scraper 24, and the bottom of the fixing block 234 abuts against the top of the scraper 24.

[0051] As Figure 1-8 shown in the figure, the two ends of the clamping block 231 are hinged with connecting rods 233. A fixing block 234 is arranged on the connecting rods 233. The fixing block 234 and the connecting rods 233 are integrally designed. The cooperation of the connecting rods 233 and the fixing block 234 can perform secondary fixing on the scraper 24 clamped and fixed by the clamping block 231. The user can rotate the connecting rods 233 to drive the fixing block 234 to rotate. The bottom of the fixing block 234 abuts against the top of the scraper 24. The fixing block 234 can prevent the scraper 24 from moving longitudinally, improve the stability of the fixing of the storage rack, improve the storage safety, and prevent the scraper 24 from being damaged.

[0052] Clamping protrusions 235 are arranged at both ends of the clamping block 231 in the Y direction, and clamping grooves 221 which are matched with the clamping protrusions 235 are arranged at both ends of the storage slot 22 in the Y direction. The clamping protrusions 235 are slidably connected with the clamping grooves 221.

[0053] AsFigure 5 , 8 As shown in 8 , the snap projection 235 is provided at the bottom of the snap block 231, and the snap groove 221 is provided at the bottom of the storage groove 22. The snap projection 235 cooperates with the snap groove 221 to longitudinally limit the snap block 231 while allowing the snap block 231 to freely move along the X direction in the storage groove 22, preventing the snap block 231 from disengaging from the storage groove 22 and thus affecting the storage of the scraper 24.

[0054] Embodiment 2:

[0055] This embodiment provides a PCB scraper storage rack. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0056] An access port 222 is provided on the storage groove 22. The access port 222 communicates with the snap groove 221 and is provided at the middle position of the storage groove 22.

[0057] As Figures 2-4 shown, the access port 222 is used to allow the snap block 231 to enter or leave the storage groove 22, facilitating the installation and disassembly of the snap block 231. Damaged parts can be replaced and repaired at any time, which is convenient for maintenance and can extend the service life of the storage rack.

[0058] The access port 222 is provided at the middle position of the storage groove 22. When the scraper 24 is stored in the storage groove 22, the snap block 231 snap-fixes the scraper 24, and at the same time, the scraper 24 limits the snap block 231, preventing the snap block 231 from disengaging from the access port 222 and thus affecting the snap-fixing function of the snap mechanism 23 on the scraper 24, improving the snap-fixing stability of the snap mechanism 23.

[0059] A limit projection 236 is provided at one end of the snap block 231 facing the elastic member 232, and the elastic member 232 is sleeved with the limit projection 236.

[0064] As Figures 6-8 shown, the protective layer 25 is used to protect the scraping blade 24, preventing the scraping blade 24 from being physically damaged due to friction with the clamping block 231 and the inner wall of the storage groove 22 during storage and retrieval, thereby affecting the performance of the scraping blade 24. At the same time, it can also maintain the sharpness of the scraping blade 24 and the accuracy of subsequent processing, and extend the service life of the scraping blade 24.

[0065] The protective layer 25 can be made of materials such as silica gel. In the present utility model, it is preferably rubber, which has strong wear resistance and corrosion resistance, and provides a good anti-slip effect, and can effectively protect the scraping blade 24 to prevent the scraping blade 24 from being damaged during storage. The protective layer 25 is adhesively connected to the clamping block 231 and the inner wall of the storage groove 22.

[0066] The storage device 2 further includes:

[0067] A transparent dust-proof cover 26, which is arranged above the placement tray 21. The placement tray 21 is provided with a placement groove 211, and the transparent dust-proof cover 26 is clamped in the placement groove 211.

[0068] As Figures 1-4 shown, the transparent dust-proof cover 26 can enable the user to observe the storage condition of the scraping blade 24 in the storage rack at any time while preventing dust, so that the user can select any scraping blade 24 for storage and retrieval.

[0069] The transparent dust-proof cover 26 is made of transparent plastic. The transparent plastic is light in weight, convenient to open and close, and has a low cost and a long service life, which can effectively reduce the maintenance cost.

[0070] The above embodiments are only the preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
