Technical Field

[0001] The utility model relates to the technical field of box body processing, in particular to a mask box bonding and glue injection device. Background Art

[0002] The mask to be processed consists of a glass / quartz substrate, a chrome layer, and a photoresist layer. Its pattern structure is achieved through a platemaking process, typically using direct-write lithography equipment such as laser direct-write lithography machines and electron-beam lithography machines. Masks are widely used in various fields involving photolithography, including ICs, FPDs, PCBs, and MEMS. Masks are packaged and transported in cassettes, which are made of fixed-size sheets joined together with glue. Traditionally, glue injection has been done manually, which is difficult to operate, results in uneven glue flow, and can easily lead to bonding problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-4 A mask box bonding and injection device includes an injection tube 1, a plate body 3 and a shell 5. The shell 5 has an electric control board 10 built in. The inner wall of the shell 5 is provided with a servo motor 11. The output end of the servo motor 11 is connected to a screw rod 8, and the screw rod 8 is threadedly connected to a rod body 7. The end of the rod body 7 is connected to a piston 6. The piston 6 is sealed and slidably connected to the injection tube 1. The output end of the injection tube 1 is threadedly connected to a needle 2. A guide strip 13 is provided on the rod body 7, and a guide port corresponding to the guide strip 13 is provided on the plate body 3.

[0019] The servo motor 11 is powered to drive the screw rod 8 to rotate, and the screw rod 8 is threadedly connected to the rod body 7. Under the restriction of the guide bar 13 and the guide port, the piston 6 is driven to move back to suck the glue into the injection tube 1. The servo motor 11 rotates in the opposite direction to drive the piston 6 to move forward to squeeze the glue out of the needle 2. After the piston 6 is squeezed to the bottom, the elastic part 9 is compressed to play a protective role to prevent the piston 6 and the injection tube 1 from being over-extruded, causing the injection tube 1 to rupture, thereby improving safety. The device can be operated with one hand, which is convenient for injecting glue into the adhesive board.

[0020] In this embodiment, the housing 5 includes a rear shell 51, an intermediate shell 52 and a front shell 53. The rear shell 51 is provided with a wiring port. The intermediate shell 52 and the front shell 53 are connected to the plate body 3 by fastening bolts 4. The rear shell 51, the intermediate shell 52 and the servo motor 11 are fixed by fastening bolts 4.

[0021] In this embodiment, a mounting hole is provided on the front shell 53, and an elastic member 9 is provided in the mounting hole. The end of the elastic member 9 is pressed on the end handle of the injection tube 1. After the piston 6 is squeezed to the bottom, the elastic member 9 is compressed, which plays a protective role, preventing the piston 6 and the injection tube 1 from being over-extruded, causing the injection tube 1 to rupture, thereby improving safety.

[0022] In this embodiment, an elastic hand strap 12 is provided on the side wall of the housing 5. Passing the hand through the elastic hand strap 12 makes it easier to hold and prevents the device from falling off.

[0023] In this embodiment, the injection tube 1 is a transparent structure, which is convenient for observing the remaining glue.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
