[0002] In the field of electronic device processing, foam is often attached to the surface of electronic devices. Foam is a material that has been foamed with plastic particles. According to its use, it can be divided into anti-static foam, conductive foam, sound-absorbing foam, etc., and is widely used in the field of electronics and electrical appliances.

[0003] After the foam is attached to the surface of the product, the release paper on the surface needs to be removed. The traditional release paper removal equipment is an independent stand-alone device. The position of the film tearing jaws usually needs to be set at a fixed point. The compatibility range is very limited and cannot adapt to the high-speed production of the automated production line. In addition, the release paper of some products is located on the side of the product, which makes it difficult to tear off the release paper, thus affecting the processing efficiency and yield of the release paper.

The carrier 21 is loaded with products to which the foam is to be adhered and moves between each station with the transmission streamline 2. The foam has been adhered to the side or the surface of the corner of the product in the previous process. The film tearing component 3 is used to peel off the release paper at the adhering position of the product, the side pressure maintaining component 4 is used to perform side pressure maintaining on the surface of the product after peeling, and the re-inspection component 5 is used to visually monitor whether the foam on the surface of the product falls off, identify good products and NG products according to the monitoring results, and perform targeted processing in the subsequent process.

[0032] In this embodiment, two sets of positioning grooves imitating the products are provided in each carrier 21, and two sets of products can be accommodated and transmitted simultaneously. The adhering surface of the product protrudes from the upper surface of the carrier 21. For each set of products, two sets of film tearing components 3 are arranged along the transmission streamline 2 to perform film tearing processing on one set of products in the carrier 21 respectively, so as to better adapt to the production rhythm of the entire adhering device and improve production efficiency.

[0033] As Figure 4As shown, the film tearing assembly 3 includes a four-axis articulated robot 31 and a film tearing support plate 32 installed at the output end of the four-axis articulated robot 31. A gripper 34 and a blowing pipe 35 are installed on the film tearing support plate 32 through a film tearing bracket 33. The gripper 34 is driven by a clamping cylinder and can clamp the end of the release paper. The blowing pipe 35 is connected to an external blowing device to blow air onto the surface of the release paper, accelerating the separation from the bonding surface. The four-axis articulated robot 31 has an in-built planar movement ability and has a certain rotation and lifting stroke, controlling the gripper 34 to move along a predetermined trajectory, which is particularly suitable for servo processing of short-distance flow lines.

[0034] The film tearing assembly 3 further includes a film tearing monitoring unit, which includes a camera one 36 arranged on the film tearing support plate 32 and a ring light source one 37 coaxially arranged with the camera one 36.

In this embodiment, the jacking drive member is a jacking cylinder 63.

[0039] Stoppers 23 are also provided on both sides of the lifting drive member, and the stoppers 23 are driven by the clamping cylinder to block the movement of the carrier 21 on the streamline, so that the carrier 21 can accurately stay at the processing position. The stoppers 23 are prior art, and the structure of the stoppers 23 is not described in detail here.
