Description

Technical Field

[0001] The present invention relates to the technical field of product bottom film removal, and specifically to a mechanism for die-cutting adhesive backing. Background Art

[0002] Die-cut adhesive-backed products are increasingly widely used in the fields of consumer electronics, new energy vehicles, medical devices and instruments, and industrial packaging. For some products or components, after special surface treatment (such as electroplating treatment, plasma treatment, parylene coating treatment, coating treatment, etc.), the adhesive backing needs to be compounded for use. Therefore, precise positioning and fitting of the adhesive backing with the product and components are required to ensure that there is no glue leakage or overflow at the edges, so as not to affect the use of customers.

[0003] The existing technical solutions for precise positioning and assembly of adhesive backing for products and components are as follows:

[0004] Positioning and fitting with a turning plate mesh box fitter. Its working principle is to take pictures of the characteristic positions on the product through a special CCD camera, industrial lens and light source, collect image data through an image processing machine (PC), perform image processing, and perform position calculation to judge the actual position of the product. By comparing with the previously set reference position, the actual offset value of the product is calculated, and by controlling the movement of the alignment platform, the product is moved to the previously set reference position to achieve fast, closed-loop, high-precision alignment. The positioning and fitting accuracy is ±0.15 mm.

[0005] Positioning and fitting with an automated robotic arm. Its working principle is to take pictures of the characteristic positions on the product through a special CCD camera, industrial lens and light source, collect image data through an image processing machine (PC), perform image processing, and perform position calculation to judge the actual position of the product. The robotic arm is controlled by a PLC to make real-time adjustments according to the image position captured by the CCD camera to achieve high-precision, fast positioning and fitting. The positioning and fitting accuracy is ±0.15 mm.

[0006] The existing technology more considers the needs of mass production of mechanical automation operations. The factory needs to evaluate the feasibility of relevant solutions, purchase and apply for relevant automated equipment, and the equipment manufacturer needs to do relevant debugging and training. The equipment cost is high, and the development and preparation cycle is too long, often taking several months of development time. Moreover, it is developed for a specific purpose. If adjustments are needed later, relevant functions need to be re-evaluated and re-developed. Relevant training for operators needs to be done in the early stage. During the die-cutting of adhesive backing, there are many equipment abnormalities and the handling is cumbersome. Often, the equipment manufacturer needs to arrange professional personnel to do debugging and maintenance. Therefore, the existing precise positioning and assembly structure of adhesive backing for components is only applicable to mass-produced products in large quantities, and has great limitations for small-batch trial production evaluation programs. Summary of the Invention

[0007] In view of the above problems, the present invention provides a mechanism for die-cutting adhesive backing, which is conveniently applied to the small-batch trial production verification or evaluation plan stage, reducing the R & D cost.

A plurality of air suction holes are arranged on the lower surface of the adhesive backing positioning grooves, and the air suction holes communicate with the inner cavity. A stripping plate is arranged on the upper surface of the upper plate of the fixture carrier plate, and a shaped stripping groove is arranged at the position corresponding to each adhesive backing positioning groove. There is one shaped stripping groove corresponding to the upper part of each adhesive backing positioning groove. The side of the inner cavity is externally connected to the air circuit switch through a pipeline, and the air circuit switch is externally connected to the vacuum generator.

[0015] It is further characterized in that:

[0016] It further includes a plurality of groups of positioning columns. A plurality of upwardly convex positioning columns are fixedly arranged on the upper plate in the peripheral area corresponding to all the adhesive backing positioning grooves. Positioning holes are respectively arranged on the stripping plate at the positions corresponding to the positioning columns. The positioning columns protrude upward after passing through the positioning holes and are used to position the incoming product to ensure the reliable and accurate alignment of the stripping plate and the upper plate;

[0021] The profiling stripping groove extends 0.07 mm outward relative to the outer shape of the adhesive backing, ensuring that the die-cut adhesive backing with a die-cutting tolerance within ±0.15 mm can reliably pass through the profiling stripping groove.
