[0055] The slide transverse movement module 23 drives the slide plate 231 and the longitudinal movement linear module 24, the vertical movement linear module 25, the carriage 22, the rotating seat 21, the detection CCD machine 222, the flip driving mechanism 215, and the glue suction head 2 on the slide plate 231 to move horizontally along the working panel 1; the longitudinal movement linear module 24 drives the vertical movement linear module 25, the slide plate 22, the rotating seat 21, the detection CCD machine 222, the flip driving mechanism 215, and the glue suction head 2 to move longitudinally along the working panel 1; the vertical movement linear module 25 drives the slide plate 22, the rotating seat 21, the detection CCD machine 222, the flip driving mechanism 215, and the glue suction head 2 to move vertically along the working panel 1 until the detection CCD machine 222 is moved to the top of the non-stick platform 11;

[0056] The detection CCD machine 222 detects the placement angle of the adhesive strip 54 to be pasted on the non-stick platform 11, and the rotating motor 221 drives the rotating seat 21 and the flip driving mechanism 215 on the rotating seat 21 and the adhesive suction head 2 to rotate at a certain angle, so that the angle of the adhesive suction head 2 is consistent with the placement angle of the adhesive strip 54 to be pasted on the non-stick platform 11;

[0057] The slide 22 further moves along three axes, so that the adhesive suction head 2 is located directly above the adhesive strip 54 to be applied, and at this time, the curved adsorption surface of the adhesive suction head 2 faces downward (such as Fig.13 shown);

[0058] The slide 22 moves downward, and the glue suction head 2 moves to the adhesive strip 54 to be pasted, and sucks the adhesive strip 54 (the top of the adhesive strip 54 to be pasted is not sticky because the protective paper 53 is pasted), and the glue pressing cylinder 41 drives the non-stick pressing block 4 to move upward, and the non-stick pressing block 4 presses the adhesive strip 54 to be pasted, so that the top of the adhesive strip 54 to be pasted fits the arc-shaped adsorption surface of the glue suction head 2, and the glue pressing cylinder 41 drives the non-stick pressing block 4 to move downward and reset;

[0059] The turning cylinder 211 pushes the pull block 214 downward, so that the rotating shaft 213, the turning platform 212 and the glue suction head 2 rotate downward and turn 90 degrees (such as Fig.14 As shown in the figure, the adhesive surface of the adhesive strip 54 to be pasted is turned to the side, and the slide 22 continues to move in three axes until the adhesive suction head 2 and the adhesive strip 54 to be pasted adsorbed thereon are moved into the watch case 5, and the adhesive suction head 2 is pressed against the adhesive groove 51 on the inner wall of the watch case 5, so that the adhesive strip 54 to be pasted adsorbed thereon can be pasted into the adhesive groove 51 on the inner wall of the watch case 5, and the adhesive suction head 2 is withdrawn. If two adhesive grooves 51 are provided on the inner wall of the watch case 5, the above-mentioned adhesive action can be repeated;

[0060] The lateral linear module 33 drives the support seat 3 to reset, the two pressing claws 31 are released, and the shifting manipulator 91 controls the finger cylinder 913 at its end to grab the glued watch case 5 on the support seat 3, and put the glued watch case 5 into the empty blanking rubber disc 56 carried by the blanking plate (at this time, the blanking plate is located directly below the blanking hole 141, and the blanking rubber disc 56 is carried on the blanking plate);

[0061] Repeat the above actions until the unloading rubber tray 56 is filled with glued watch cases 5, and the two rubber tray cylinders 911 at the end of the shifting manipulator 91 drive the corresponding three-finger electric grippers 912 to move downward, and the two three-finger electric grippers 912 grab the topmost empty rubber tray on the loading plate 83 and place the rubber tray on the top of the rubber tray carried by the unloading plate to form a new unloading rubber tray 56 (the loading plate 83 will gradually move up as the loading rubber tray 55 is continuously reduced), and the shifting manipulator 91 can continue to put the glued watch cases 5 in the unloading rubber tray 56, and the unloading plate will gradually move downward as the unloading rubber trays 56 are continuously stacked;

[0062] When all the rubber discs on the loading plate 83 are moved to the unloading plate, the unloading linear module drives the unloading support frame and the unloading plate it supports to move downward together until the unloading plate is supported on the unloading conveyor belt. The unloading motor drives the unloading conveyor belt to run, and the unloading plate and the stack of rubber discs with attached watch cases 5 it supports can be conveyed to the unloading end of the unloading frame 133 for unloading.

[0063] In the automatic bonding equipment for the inner wall rubber strip of the watch case of the present invention, a loading plate 83 and a unloading plate are provided at one end of the working panel 1, which are respectively used for the input and output of the product (i.e., the watch case 5), thereby realizing continuous processing of the product; a glue feeding mechanism 6 is provided at the other end of the working panel 1, which is responsible for conveying the rubber strip 54 to be pasted to the designated position as required; a non-stick platform 11 is provided next to the glue feeding mechanism 6, which is used for temporarily placing the rubber strip 54 to be pasted, so as to prevent the rubber strip from becoming ineffective due to adhesion before being used; at the same time, a glue transferring mechanism 7 is provided at the output end of the glue feeding mechanism 6, which can accurately move the rubber strip 54 to be pasted conveyed by the glue feeding mechanism 6 to the non-stick platform 11. Between the glue transfer mechanism 7 and the loading plate 83, the present invention cleverly arranges a bearing seat 3, a glue application mechanism 26 and a shifting manipulator 91. The bearing seat 3 is laterally slidably arranged between the loading plate 83 and the non-stick platform 11, and is used to carry the product to be glued; the glue application mechanism 26 is responsible for absorbing the glue strip 54 to be applied on the non-stick platform 11, and flipping it over and attaching it to the inner wall of the product on the bearing seat 3. During this process, the glue application mechanism 26 can flexibly adapt to the surface changes of the inner wall of the product to ensure that the glue strip fits tightly with the inner wall of the product. In addition, the shifting manipulator 91 plays a vital role in the entire glue application process. It can accurately move products between different workstations to ensure that the products can be processed according to the predetermined process flow. This automated movement method not only improves production efficiency, but also ensures the consistency and accuracy of glue application.

[0064] In summary, the automatic glue sticking device for the inner wall of the watch case proposed in the present invention realizes the automation, efficiency and precision of the glue sticking operation on the inner wall of the product through its unique layout of the working panel 1 and the design of each functional module. Compared with the prior art, the device has higher flexibility and adaptability when processing the inner wall of the product with complex curved surface structure, can significantly improve the glue sticking quality and production efficiency, and brings significant technological progress and economic benefits to the modern manufacturing industry.

[0065] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
