[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Referring to Figures 1 to 5, a glue-dispensing clamp of the present invention includes: a base 1; a clamping plate 3, which abuts against the base 1 and forms a clamping space between the clamping plate 3 and the base 1; a pressure plate 2, which is hinged to the base 1, and is connected to a stop block 21. The pressure plate 2 is also clamped to a pressure block 22, and an elastic element 24 is provided between the pressure block 22 and the stop block 21. The pressure block 22 can abut against the clamping plate 3, and the clamping plate 3 is located between the pressure block 22 and the base 1.

[0027] This embodiment provides a glue-filling clamp. The shell to be glued is placed on the base 1, and the screen to be glued is placed at the mounting position of the shell, abutting against the clamping plate 3. The pressure plate 2 is rotated, causing the pressure block 22 to abut against the top of the clamping plate 3. At this time, the elastic element 24 is compressed, and the clamping plate 3 is subjected to pressure, thereby stably clamping the shell to be glued and the screen. Through the hinge between the pressure plate 2 and the base 1, and the cooperation between the pressure block 22 and the elastic element 24, the rotation of the pressure plate 2 allows the pressure block 22 to apply pressure to the clamping plate 3, thus stably clamping the shell to be glued and the screen between the clamping plate 3 and the base 1. The clamping and disassembly process only requires rotating the pressure plate 2, eliminating the need to rotate multiple bolts, thereby improving clamping and disassembly efficiency.

[0028] Referring to Figure 6, the base 1 is generally flat. A rectangular limiting groove 11 is provided in the middle of the base 1. The limiting groove 11 is used to accommodate the shell to be filled with glue. The shell to be filled with glue can abut against the side wall of the limiting groove 11, thereby fixing the horizontal position of the shell to be filled with glue. A guide groove 12 is provided on the inner edge of the limiting groove 11. The guide groove 12 is arranged around the edge of the limiting groove 11. During glue filling, the glue can flow along the guide groove 12, thereby guiding the flow direction of the glue.

[0029] Referring to Figure 5, the clamping plate 3 is generally flat. The clamping plate 3 and the base 1 form a clamping space for clamping the shell to be glued and the screen. The clamping plate 3 includes a detachable adsorption part 4. The clamping plate 3 is provided with multiple limiting rods 32 arranged in a cross shape. The body of the clamping plate 3 is engaged with the adsorption part 4 through the limiting rods 32. The adsorption part 4 of the clamping plate 3 is provided with four material passage holes 41 corresponding to the guide groove 12. The material passage holes 41 are located near the four corners of the adsorption part 4. The external glue dispensing equipment is connected to the material passage holes 41. The glue flows through the material passage holes 41 into the guide groove 12, and then the glue enters between the shell to be glued and the screen.

[0030] Referring to Figures 6 and 7, the bottom of the clamping plate 3 is provided with a positioning post 33, and the base 1 is provided with a positioning hole 15 corresponding to the position of the positioning post 33. The positioning post 33 can pass through the positioning hole 15, and the positioning post 33 and the positioning hole 15 can slide relative to each other. Through the cooperation of the positioning post 33 and the positioning hole 15, the clamping plate 3 can be positioned for installation, and the horizontal direction of the clamping plate 3 can also be fixed.

[0031] The suction part 4 of the clamping plate 3 is also provided with multiple air holes 42, which are disposed through the clamping plate 3 and correspond to the positions of the limiting grooves 11. The top of the air holes 42 are connected to an external air extraction device. By extracting air through the external air extraction device, the screen to be coated with glue can be attached to the bottom of the clamping plate 3. Thus, by moving the clamping plate 3, the screen to be coated with glue can be moved together, avoiding screen contamination caused by the screen moving alone.

[0032] Referring to Figures 2 to 4, two pressure plates 2 are hinged to the two side edges of the base 1 and are arranged opposite each other. Each pressure plate 2 is connected to a stop block 21 and also has a pressure block 22 engaged. An elastic element 24 is provided between the pressure block 22 and the stop block 21. The pressure block 22 can abut against the clamping plate 3, which is located between the pressure block 22 and the base 1. Specifically, the pressure plate 2 is hinged to the base 1 via two connecting parts 23. The base 1 is connected to a rotating shaft 14, and the connecting parts 23 are rotatably connected to the rotating shaft 14. An opening is provided on the side of the pressure plate 2 closest to the base 1, located between the connecting parts 23. This opening prevents the pressure plate 2 from colliding with the clamping plate 3 during rotation.

[0033] The pressure plate 2 has multiple mounting slots 27 on the side away from the base 1. A stop block 21 is located within the mounting slot 27 and is connected to the pressure plate 2 via fasteners 26. The fasteners 26 are threadedly connected to the stop block 21 and the bottom of the mounting slot 27 in sequence; the fasteners 26 can be considered as bolts. A through hole 28 is provided at the bottom of the mounting slot 27, and a pressure block 22 engages with the through hole 28, with a portion of the pressure block 22 located outside the through hole 28. Specifically, the pressure block 22 is spherical, and the end of the through hole 28 away from the mounting groove 27 is provided with a radially arranged protruding edge 29. The protruding edge 29 is arranged around the edge of the through hole 28. By setting the protruding edge 29, the diameter of the corresponding position of the protruding edge 29 in the through hole 28 is smaller than the diameter of the through hole 28. The pressure block 22 abuts against the side wall of the through hole 28, and at the same time, the pressure block 22 also abuts against the protruding edge 29. That is, the diameter of the pressure block 22 is larger than the diameter of the corresponding position of the protruding edge 29 in the through hole 28, so that the pressure block 22 is engaged with the through hole 28. At the same time, part of the pressure block 22 is located outside the through hole 28, and the through hole 28 is connected to the opening. The edge of the clamping plate 3 can be located inside the opening and abut against the pressure block 22 protruding from the through hole 28. The elastic element 24 can be considered as a spring. A baffle 25 is also provided between the elastic element 24 and the pressure block 22. The baffle 25 is attached to the side wall of the through hole 28 and can slide within the through hole 28. The end of the elastic element 24 and the pressure block 22 both abut against the baffle 25. The baffle 25 prevents the abutment positions of the elastic element 24 and the pressure block 22 from being misaligned, which would cause the pressure block 22 to apply different pressures to the clamping plate 3. The side of the baffle 21 near the bottom of the mounting groove 27 is provided with a receiving hole. The receiving hole is connected to the through hole 28 and their center lines are collinear. The elastic element 24 is located in the receiving hole and the through hole 28, that is, the elastic element 24 is located in the receiving cavity formed by the receiving hole and the through hole 28. The baffle 21 abuts against the bottom of the mounting groove 27, so that the pressures applied by the multiple pressure blocks 22 to the clamping plate 3 are all the same.

[0034] Referring to Figure 5, the clamping plate 3 is also provided with a slot 31. The edge of the slot 31 is arc-shaped. During the movement of the pressure block 22, the pressure block 22 protrudes from the through hole 28 and can enter the slot 31. At this time, the pressure block 22 is in a state of applying pressure to the clamping plate 3. The pressure applied to the pressure block 22 by the elastic member 24 makes the pressure block 22 engage with the slot 31. The arc-shaped edge of the slot 31 can prevent the pressure block 22 from being damaged during the movement.

[0035] Referring to Figure 6, a plurality of support columns 13 are provided on the base 1 near the edge of the pressure plate 2. The plurality of support columns 13 are equidistantly arranged along the edge of the pressure plate 2. The support columns 13 are detachably connected to the clamping plate 3. By setting the support columns 13, the levelness of the clamping plate 3 can be adjusted. According to the different thicknesses of the shell and screen to be potted, different support columns 13 can be replaced to adjust the distance between the clamping plate 3 and the base 1.

[0036] In use, the shell to be glued is placed in the limiting groove 11 of the base 1. The screen to be glued is attached to the bottom of the clamping plate 3 by the external air extraction device. The clamping plate 3 is moved so that the screen to be glued is in the installation position of the shell. The pressure plate 2 is rotated so that the pressure block 22 abuts against the top of the clamping plate 3. At this time, the elastic element 24 is compressed and the clamping plate 3 is under pressure. The shell to be glued and the screen are stably clamped. Finally, the external glue dispensing device dispenses glue into the feed hole 41. The glue flows through the feed hole 41 and enters the guide groove 12 until the glue enters between the shell to be glued and the screen.

[0037] This utility model discloses a glue-filling clamp. Through the hinge between the pressure plate 2 and the base 1, and the cooperation between the pressure block 22 and the elastic element 24, the pressure block 22 can apply pressure to the clamping plate 3 by rotating the pressure plate 2. This allows the shell to be glued and the screen to be stably clamped between the clamping plate 3 and the base 1. The clamping and disassembly process only requires rotating the pressure plate 2, without rotating multiple bolts, thereby improving the clamping and disassembly efficiency.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
