Description

Technical Field

[0001] This utility model relates to the field of gluing equipment technology, and in particular to an automatic gluing device for polishing discs. Background Technology

[0002] Some polishing pads need to be fixed to a base so that users can hold them and perform polishing operations. When producing polishing pads, an adhesive applicator is used to apply adhesive to the base, and then the polishing pad is pressed into the base so that the polishing pad and the base are bonded and fixed together with adhesive.

[0003] For example, Chinese patent application number "CN202220366347.8" is entitled "An Automatic Glue Application Device for Polishing Sheets". Its structure includes: a frame and a lower mold positioning plate. The lower mold positioning plate is fixed on the frame. A material application mechanism is also provided on the side of the frame. The material application mechanism includes a slide rail, a feeding base, and a push plate. There are two slide rails installed on the frame. The push plate is stacked on the feeding base and the feeding base is engaged with the slide rail. The lower mold positioning plate has regularly distributed positioning grooves. The feeding base and the push plate have feeding holes corresponding to the positions of the positioning grooves. By providing a material application mechanism next to the lower mold positioning plate, when the equipment is applying glue to the base, the operator can place the polishing sheets on the staggered feeding base and push plate. After the glue application is completed, the feeding base is used to bring the polishing sheets to the top of the base. Then, the push plate is pushed to place all the polishing sheets on the base at once, so that the polishing sheets and the base are bonded and fixed with glue, thus speeding up the production process.

[0004] However, after the device glues the polishing disc to the base, it is not easy to demold. Forcibly removing it can easily damage the product, which seriously affects the product yield. Secondly, after demolding, residues are easily stuck to the inner wall of the lower template positioning plate, which is inconvenient to handle and can have an adverse effect on product manufacturing, making it easy to produce unqualified defective products. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic gluing device for polishing sheets. By incorporating a limiting groove and bolts, it facilitates more precise material feeding of the polishing sheets. A demolding device is also included to facilitate the demolding of the product inside the mold cavity using air pressure, preventing product damage and simultaneously cleaning residue inside the mold cavity, thereby improving production efficiency.

[0006] This utility model also provides an automatic gluing device for a polishing sheet as described above, comprising: a worktable, a movable component above the worktable, a gluing head below the movable component, a lower template on the surface of the worktable, multiple mold grooves on the surface of the lower template, a demolding device on the bottom wall of the mold groove, limiting grooves on both sides of the surface of the lower template, slide rails fixedly connected above the worktable and on both sides of the lower template, a feeding tray slidably connected to the slide rails, a placement groove on the upper surface of the feeding tray, bolts threaded onto the feeding tray, a push plate slidably connected to the bottom of the feeding tray, and a pressure pad fixedly connected to the bottom of the push plate. The limiting grooves and bolts facilitate more precise feeding of the polishing sheet, and the demolding device allows for demolding of the product inside the mold groove using air pressure, preventing product damage and cleaning residue inside the mold groove, thus improving production efficiency.

[0007] According to the automatic gluing device for polishing sheets, the demolding device includes a first slide groove disposed on the bottom wall of the mold groove. A first cylinder is fixedly connected to the bottom wall of the first slide groove, and a first sealing block is fixedly connected to the output end of the first cylinder. An air inlet pipe is disposed on one side of the first slide groove, and a second slide groove is disposed on the other side of the first slide groove and located on the bottom wall of the mold groove. A second cylinder is fixedly connected to the bottom of the second slide groove, and a second sealing block is fixedly connected to the output end of the second cylinder. An air outlet pipe is disposed on one side of the second slide groove. The first sealing block is output by the first cylinder, and air pressure is delivered to the inside of the first slide groove through the air inlet pipe, thereby using air pressure to demold the product. Then, the second sealing block is output by the second cylinder, causing the second sealing block to move to the bottom of the air outlet pipe and seal the upper end of the mold groove. Airflow is delivered to the inside of the mold groove through the air inlet pipe to clean the residue on the inner wall of the mold groove and discharged through the air outlet pipe.

[0008] According to the automatic gluing device for polishing discs, the first sealing block and the second sealing block are slidably connected by the first and second sliding grooves. Air pressure leakage is prevented by the first and second sealing blocks.

[0009] According to the automatic gluing device for polishing discs, the air inlet pipe and the air outlet pipe correspond to each other, facilitating the input and output of gas through the air inlet pipe and the air outlet pipe.

[0010] According to the automatic gluing device for polishing sheets, the number of mold slots and the number of placement slots correspond to each other and are of the same size. When the placement slot is located directly above the mold slot, it is convenient to place the polishing sheet into the mold slot through the placement slot.

[0011] According to the automatic gluing device for polishing sheets, the bottom of the pusher plate is higher than the surface of the lower template, and the pressure pad is adapted to the surface of the lower template. The pressure pad facilitates uniform compression of the polishing sheet, thereby accelerating production speed.

[0012] According to the automatic gluing device for polishing discs, the bolt is threadedly connected to the limiting groove. This threaded connection facilitates stability of the placement groove when the polishing disc is placed.

[0023] The demolding device 6 includes a first slide groove 601 disposed on the bottom wall of the mold groove 5. A first cylinder 602 is fixedly connected to the bottom wall of the first slide groove 601. A first sealing block 603 is fixedly connected to the output end of the first cylinder 602.
