Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to an automatic glue applicator for artificial diamond resin elastic grinding blocks. Background Art

[0002] An automatic glue applicator for artificial diamond resin elastic grinding blocks is a device specifically designed for the automated production of artificial diamond resin elastic grinding blocks. Through a series of automated operations, such as automatically transporting elastic grinding blocks, automatically applying resin, and automatically fixing, etc., the efficient and precise production of artificial diamond resin elastic grinding blocks is achieved.

[0003] In the traditional method of gluing elastic grinding blocks, workers place the elastic grinding blocks on the workbench, then press an object on the elastic grinding blocks to prevent the elastic grinding blocks from falling off the workbench. Subsequently, workers apply resin to the elastic grinding blocks. During this process, it is necessary to clamp the elastic grinding blocks and then evenly apply glue to them. After the glue application is completed, the elastic modules are collected in a receiving box.

[0004] For example, the patent publication number: CN220074430U discloses an automatic glue applicator for diamond resin elastic grinding blocks. Through the settings of a lifting seat, a sliding groove, a lifting rod, a connecting plate, a lifting block, a screw rod, a lifting groove, a first bevel gear, a second bevel gear, and a rotating shaft, rotating the rotating shaft can control the lifting of the cylinder and keep it stable without lateral displacement of the cylinder; through the settings of a sleeve, an annular groove, a communicating groove, a clamping groove, a clamping block, a limiting groove, a limiting ring, and a return spring, the sleeve cannot control the rotation of the rotating shaft when not in use, which can prevent personnel from accidentally touching the sleeve and causing the cylinder to lift.

[0005] Although the above device can achieve the pressing work of elastic grinding blocks, the above existing devices still have deficiencies in positioning, spraying glue, and automatic blanking of elastic grinding blocks. At the same time, for the glue liquid in the glue storage barrel, it is necessary to efficiently stir the glue liquid. Otherwise, when the glue liquid is conducted to the glue spraying head, the fluidity of the glue liquid will be reduced.

Detailed implementation manners

[0036] The present invention will be further described below with reference to the accompanying drawings: As shown in the figure Figures 1 - 16, this embodiment provides an automatic glue - sticking machine for artificial diamond resin elastic grinding blocks, which includes a workbench 1, a material - receiving box 2, and a support frame 3. The material - receiving box 2 is arranged on one side of the workbench 1, and the support frame 3 is fixedly installed on the other side of the workbench 1. A plurality of placement grooves 4 for placing elastic grinding blocks are formed on the workbench 1. It is characterized in that: clamping components 5 for clamping elastic grinding blocks are arranged inside the inner walls on both sides of the placement groove 4. A push plate 6 is slidably clamped on the bottom surface of the placement groove 4. A plurality of driving components 7 for driving the movement of the push plate 6 are arranged inside the workbench 1. A glue - spraying component 8 connected to the workbench 1 is arranged above the placement groove 4; The glue - spraying component 8 includes a glue - spraying head 801. Above the support frame 3, there is a glue storage barrel 9. Inside the glue storage barrel 9, there is a stirring component 10 for stirring the glue liquid. One side of the glue storage barrel 9 is communicated with a glue - discharging pump 11. The output end of the glue - discharging pump 11 is communicated with a pipe fitting 12, and the pipe fitting 12 can be communicated with the glue - spraying head 801. A pushing frame 13 is arranged on the support frame 3, and pushing components 14 are evenly arranged on the pushing frame 13. The pushing components 14 are used for pressing the elastic grinding blocks.

[0037] As Figure 1 shown, an inclined boss 15 is arranged on one side surface of the workbench 1, and the material - receiving box 2 is arranged below the inclined boss 15, so that the elastic grinding blocks sprayed with glue can be automatically pushed into the material - receiving box 2 by the driving component 7.

[0038] As Figure 12 shown, clamping grooves 16 are symmetrically formed on the inner walls on both sides of the placement groove 4. The clamping component 5 includes a clamping cylinder 501 fixedly installed in the clamping groove 16. The clamping component 5 further includes a clamping plate 502. The output end of the clamping cylinder 501 is fixedly connected to the clamping plate 502. The clamping plate 502 is made of rubber material. So that after the staff places the elastic grinding block in the placement groove 4, the external controller controls the clamping cylinder 501 to clamp the elastic grinding block, and then different - shaped elastic grinding blocks can be clamped.

[0039] As Figure 12 shown, a clamping groove is formed at the bottom of the placement groove 4, and the lower end of the push plate 6 is slidably clamped in the clamping groove. The driving component 7 includes a driving lead screw 701 rotatably installed in the clamping groove. One end of the driving lead screw 701 extends to the outside of the rear side of the workbench 1.

Sliding grooves are formed on both inner walls of the running groove 17. The sliding rod 805 is slidably clamped with the sliding grooves. When a staff member places an elastic grinding block in the placing groove 4, by starting the hub motor 804, the hub motor 804 can drive the rotating gear 802 to rotate. At this time, the rotating gear 802 starts to rotate with the fixed rack 19. By the limiting of the moving frame 803 by the linear bearing 806, the moving frame 803 can move along the length direction of the placing groove 4.

[0041] A linear bearing 806 is fixedly installed in the guiding groove 18. The other end of the moving frame 803 is sleeved on the surface of the linear bearing 806. An adjusting lead screw 807 is rotatably installed inside the upper end of the moving frame 803. An adjusting motor 808 is fixedly installed at one end of the adjusting lead screw 807.

A visual sensor 810 is fixedly installed on the glue spraying head 801. By starting the adjusting motor 808 (the adjusting motor 808 is a servo motor), the adjusting motor 808 can drive the adjusting lead screw 807 to rotate. By electrically connecting the visual sensor 810 to an external controller, and then through the connection between the controller and the adjusting motor 808, the movement of the moving ring 809 can drive the movement of the glue spraying head 801 to realize precise spraying of the elastic grinding block.

[0042] As Figure 11As shown in the figure, the stirring assembly 10 includes a stirring motor 1001. A docking rod 1002 is fixedly installed at the output end of the stirring motor 1001.

A cross insertion groove 1006 is formed at the upper end and the lower end of the stirring rod 1004. A cross insertion rod 1007 is rotatably installed in the glue storage barrel 9. The cross insertion rod 1007 is inserted into the cross insertion groove 1006. When a staff member turns on the stirring motor 1001, the stirring motor 1001 can drive the docking rod 1002 to rotate. Then, through the connection between the docking cross rod 1003 and the stirring rod 1004, the stirring motor 1001 can drive the stirring rod 1004 to rotate. At this time, the glue liquid is stirred by the stirring rod 1004. Due to the detachable connection between the stirring rod 1004, the cross insertion rod 1007 and the docking cross rod 1003, it is convenient for the staff member to replace and disassemble the stirring rod 1004.

[0043] As Figure 7 shown, the pipe fitting 12 includes a main pipe 1201 and two sub - pipes 1202. One end of the main pipe 1201 and the sub - pipes 1202 is in communication with the glue outlet pump 11. The main pipe 1201 and the sub - pipes 1202 are both spring telescopic pipes 1203. The free ends of the main pipe 1201 and the sub - pipes 1202 are in communication with the glue spraying head 801. When the moving frame 803 moves, the glue liquid in the glue storage barrel 9 can be introduced into the glue spraying head 801 through the main pipe 1201 and the sub - pipes 1202 by the glue outlet pump 11, so as to realize the spraying on the elastic grinding block.

[0044] As Figure 5 shown, the pushing assembly 14 includes a pushing cylinder 1401. The pushing cylinder 1401 is fixedly installed on the lower surface of the pushing frame 13. A detachable pressing plate 1402 is fixedly installed at the output end of the pushing cylinder 1401.
