Description

Technical Field

[0001] This utility model relates to the field of automatic adhesive applicator technology, specifically to a roller adsorption device for an adhesive applicator. Background Technology

[0002] Adhesive application equipment is an automated device used to precisely attach various types of tapes, films, protective films, double-sided tapes, and other materials to the surface of products. Its applications are extremely wide-ranging, covering almost all modern manufacturing sectors requiring precise, efficient, and consistent bonding, such as electronic component processing, automotive parts assembly, home appliance manufacturing, and medical device manufacturing.

[0003] Most existing automatic adhesive applicator equipment still uses a pressure-pressing method, where an adsorption head picks up the adhesive sheet and presses it onto the product. This method is prone to problems when applying large adhesive sheets, as air bubbles inside the sheet cannot be completely expelled, leading to poor adhesion. Furthermore, the adsorption heads on existing automatic adhesive applicators are usually fixed to the moving mechanism with screws. When changing products, if the adsorption head needs to be replaced, the entire head must be disassembled and a new one reinstalled. Therefore, the adsorption structure of existing automatic adhesive applicators suffers from problems of poor adhesion and difficulty in replacement, necessitating structural improvements.

[0018] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-6 As shown, a roller adsorption device for an adhesive applicator is provided. The adhesive applicator is equipped with a motion mechanism, and the roller adsorption device is installed on the motion mechanism. The adhesive applicator drives the conveying mechanism, which in turn drives the roller adsorption device to complete the process of adsorbing adhesive sheets and applying adhesive.

[0021] The roller adhesive adsorption device mainly includes a suction head mounting plate 1, a connecting seat 2, a negative pressure adsorption assembly 3, a negative pressure connecting pipe 4, and a roller assembly 5. The suction head mounting plate 1 serves as the main load-bearing structure, with the connecting seat 2 fixedly mounted on its upper part. The connecting seat 2 is used to connect to the motion mechanism of the adhesive applicator (not shown in the figure). The suction head mounting plate 1 has multiple weight-reducing perforations 11 to reduce the overall weight and improve flexibility.

[0022] The negative pressure adsorption component 3 is detachably snapped onto the suction head mounting plate 1. Multiple adsorption holes 31 are evenly distributed on the lower surface of the negative pressure adsorption component 3. One end of the negative pressure connecting pipe 4 is connected to each adsorption hole 31, and the other end is connected to a negative pressure device. During operation, the negative pressure device draws air from the adsorption holes 31 through the negative pressure connecting pipe 4, generating negative pressure suction on the adsorption holes 31, thereby enabling the negative pressure adsorption component 3 to pick up the film.

[0023] Specifically, the lower end face of the suction head mounting plate 1 is machined with a dovetail groove 12. The negative pressure adsorption assembly 3 includes a snap-fit ​​block 32 and an adsorption plate 33. Snap-fit ​​protrusions 34 matching the dovetail groove 12 are formed on both sides of the snap-fit ​​block 32, and the snap-fit ​​protrusions 34 are detachably snapped into the dovetail groove 12. Through the cooperation of the snap-fit ​​protrusions 34 and the dovetail groove 12, the snap-fit ​​block 32 is snapped and fixed to the suction head mounting plate 1, thus connecting and fixing the negative pressure adsorption assembly 3 to the suction head mounting plate 1. By pulling the snap-fit ​​block 32, the snap-fit ​​protrusions 34 can be pulled out from the dovetail groove 12, thereby achieving the purpose of disassembling the negative pressure adsorption assembly 3. The adsorption plate 33 is sealed to the lower end face of the snap-fit ​​block 32, and adsorption holes 31 are evenly distributed on the adsorption plate 33. During operation, the negative pressure generated by the adsorption hole 31 can adsorb the film onto the surface of the adsorption plate 33, thus achieving the purpose of gripping the film; when releasing the film, simply disconnect the negative pressure of the adsorption hole 31, and the film will automatically detach from the surface of the adsorption plate 33.

[0024] To ensure a stable negative pressure in the adsorption holes 31, a perforated groove 35 is provided on the lower end face of the snap-fit ​​block 32. A connecting hole 36 is provided on the snap-fit ​​block 32, connecting to both the negative pressure connecting pipe 4 and the perforated groove 35. The perforated groove 35 is connected to the adsorption holes 31. By providing the perforated groove 35 and connecting hole 36 on the snap-fit ​​block 32, each adsorption hole 31 on the adsorption plate 33 can be connected to the negative pressure connecting pipe 4, resulting in a uniform negative pressure suction force in each adsorption hole 31. This ensures that the adsorption plate 33 can stably adsorb the film, improving processing stability.

[0025] To improve sealing, a sealing ring 6 is provided on the upper surface of the snap-fit ​​block 32. The sealing ring 6 is fitted around the connecting hole 36 and makes a sealing contact with the suction head mounting plate 1. By setting the sealing ring 6, the snap-fit ​​block 32 and the suction head mounting plate 1 can be connected and sealed to prevent air leakage and ensure the stability of the processing of adhesive films and the application of adhesive.

[0026] like Figure 6 As shown, the roller bonding assembly 5 is fixedly connected to the suction head mounting plate 1, and the roller bonding assembly 5 is located on one side of the negative pressure adsorption assembly 3. Specifically, the roller bonding assembly 5 includes a roller bonding mounting base 51 fixedly mounted on the suction head mounting plate 1. Two symmetrically positioned lifting drive components 52 are mounted on the roller bonding mounting base 51. In this embodiment, the lifting drive components 52 are cylinders. The output ends of the lifting drive components 52 are connected to a roller mounting frame 53. A freely rotatable roller bonding roller 54 is mounted on the roller mounting frame 53 via bearings and a rotating shaft. During the roller bonding process, the lifting drive components 52 drive the roller mounting frame 53 to lower the roller bonding roller 54, causing the roller bonding roller 54 to come into contact with the adhesive sheet. Then, under the action of the motion mechanism of the adhesive applicator, the roller bonding adsorption device is driven to move horizontally, and the roller bonding roller 54 will roll on the surface of the adhesive sheet, thereby attaching the adhesive sheet to the surface of the product. After the roll application is completed, the lifting drive 52 drives the roller mounting frame 53 to reset and rise the roll application roller 54, causing the roll application roller 54 to separate from the film.

[0027] To ensure smooth lifting of the roller mounting frame 53, two roller lifting guide rods 55 are fixed on the roller mounting frame 53, and two roller lifting guide sleeves 56 are installed at corresponding positions on the roller mounting base 51. The roller lifting guide rods 55 pass through the corresponding roller lifting guide sleeves 56 and can slide up and down. The cooperation between the roller lifting guide rods 55 and the roller lifting guide sleeves 56 limits and guides the movement direction of the roller mounting frame 53, improving the accuracy of the transmission.

[0028] In addition, a limit buffer 57 is installed on the roller mounting base 51, which can abut against the roller mounting frame 53. The limit buffer 57 is used to contact the roller mounting frame 53 when it rises to its highest position, so as to limit and buffer the movement.

[0029] Working principle: During processing, the external negative pressure device generates negative pressure at the adsorption hole 31 through the negative pressure connecting pipe 4, the connecting hole 36, and the hollow groove 35. The motion mechanism of the adhesive applicator moves the entire roller adsorption device to the position of the adhesive sheet, and the bottom surface of the adsorption plate 33 contacts and adsorbs the adhesive sheet. Then, the motion mechanism of the adhesive applicator moves the roller adsorption device with the adsorbed adhesive sheet to the starting attachment position on the surface of the product to be adhered. Then, the lifting drive 52 is activated, pushing the roller mounting frame 53 and the roller roller 54 downward until the roller roller 54 abuts against the adhesive sheet and presses down one end of the adhesive sheet.

[0030] Then, the negative pressure of the negative pressure adsorption component 3 is released, and the film is placed on the adhesive application position on the product. The motion mechanism of the adhesive applicator then drives the roller adsorption device to move horizontally, maintaining appropriate downward pressure while moving along a predetermined application path (e.g., from one end of the product to the other). During this process, the roller 54 rolls on the film under frictional force, gradually rolling and adhering the film from the starting end to the product surface, and completely expelling any air between them.

[0031] After the film is fully applied, the lifting drive 52 drives the rolling roller 54 to rise and reset, detaching it from the film surface. The conveying mechanism then drives the rolling adsorption device back to the ready position, preparing for the next application operation.

[0032] When it is necessary to replace the negative pressure adsorption component 3, simply hold the negative pressure adsorption component 3 by hand and apply horizontal force along the guide direction of the dovetail groove 12 to slide it off the suction head mounting plate 1. When installing a new negative pressure adsorption component 3, align its locking protrusion 34 with the entrance of the dovetail groove 12 and push it horizontally until it is in place to complete the installation. The whole process is quick and easy.

[0033] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
