Description

Technical Field

[0001] The invention belongs to the technical field of positioning and placing glue, and in particular is a mechanism for positioning and placing glue. Background Art

[0002] During the product processing process, it is sometimes necessary to attach film to the product, and when attaching the film, a film carrier and a product processing table are usually required. In the production, transportation and processing of the film, the film carrier plays a vital role. It can effectively fix the film, prevent contamination, and improve production efficiency. When used, the film carrier can ensure that the film is accurately positioned during placement and processing, and can effectively protect the film from scratches, contamination and other physical damage. The product processing table is used to position and fix the product to be attached with film to avoid product offset when attaching the film. Therefore, a glue picking and placing mechanism with precise positioning is required.

[0003] The existing precise positioning glue picking and placing mechanism has certain disadvantages when in use. When in use, the existing precise positioning glue picking and placing mechanism usually uses a clamping mechanism to clamp the film on the film carrier and then attach it to the product. Since the structure of the film is usually a long and narrow flexible structure, the clamping force of the clamping mechanism is uneven or the clamping point is improperly positioned when clamping the film, which easily causes the film to bend and deform, and thus cannot be accurately attached to the product. When using the clamping mechanism, excessive clamping force may tear or scratch the film, resulting in waste, while excessive clamping force may cause the film to fall during transportation, causing economic losses to people, thereby reducing the use effect of the precise positioning glue picking and placing mechanism and failing to meet people's needs.

When the adsorption chamber 16 returns to normal pressure, the cleaning structure 19 closes the adsorption hole 18.

[0047] The cleaning structure 19 in the present invention includes a cleaning rod 21 movably arranged in the adsorption hole 18 and a filtering structure 22 movably connected to the bottom end of the cleaning rod 21.

The driving structure 15 and the clamping block 14 cooperate to clamp and fix the film. The adsorption chamber 16, the adsorption strip 17 and the adsorption hole 18 adsorb and fix the film. The positioning column 8 accurately transfers the clamped film to the top of the product processing table 2 to achieve precise attachment. The clamping structure 4 and the adsorption structure 5 work together to separate the film from the adsorption strip 17 so that the next round of operation can be carried out. The synergistic effect of the clamping components ensures that the film can achieve high-precision positioning in each link, reducing the time for manual intervention and adjustment, speeding up the production rhythm, and consistent positioning and fixing methods make the processing process of each film the same, ensuring the stability of product quality and reducing the scrap rate caused by inaccurate positioning or loose fixation.

[0057] When the adsorption chamber 16 is formed into a negative pressure chamber, the moving structure 20 can control the connecting frame 34 and the connecting rod 35 to drive the cleaning rod 21 to move in the adsorption hole 18, so that the buffer structure 23 drives the filter structure 22 to move out of the adsorption hole 18, so that the adsorption hole 18 adsorbs and fixes the film. When the adsorption chamber 16 is restored to normal pressure, the moving part 26 and the connecting frame 34 move downward under the action of gravity, and the first buffer spring 27 cooperates with the third buffer spring 39 to make the cleaning rod 21 move up and down. The buffer part 30, the second buffer block 31, the second guide rod 33 and the second buffer spring 32 control the filter block 24 to move up and down in the adsorption hole 18 to clean up the impurities in the adsorption hole 18. The filter block 24 knocks on the film to separate the film from the adsorption strip 17. The entire adsorption, fixing and cleaning process does not require manual intervention, which improves production efficiency and can thoroughly clean the impurities in the adsorption hole to ensure the adsorption effect and film quality. The coordinated work between the various structures is stable and reliable, reducing the probability of failure.
