A robotic arm gripper for an automated vacuum coating production line

Abstract

This utility model discloses a robotic arm gripper for an automated vacuum coating line, comprising a slide rail with two sliding blocks slidably mounted on it. The sliding blocks are driven by a cylinder. Each sliding block has a base, and gripper arms are mounted at both ends of the base. A pad, made of polyurethane elastomer, is mounted on the inner side of each gripper arm. In this utility model, the inner side of the pad that contacts the substrate is grooved, with a certain degree of redundancy, ensuring the substrate is fully contained within the groove when the gripper grasps it, while also preventing the substrate from detaching from the gripper. Since the contact between the pad and the substrate is mostly planar, friction is reduced. Furthermore, the polyurethane elastomer material of the pad generates fewer frictional particles when in contact with the metal substrate, thus reducing the occurrence of crystal defects.

Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, specifically a robotic arm gripper for an automated vacuum coating line. Background Technology

[0002] The existing grippers are made of aluminum alloy, as is the substrate. The substrate is gripped via a concave-convex clamping mechanism. Because the gap between the slots in the temporary storage rack is greater than the substrate thickness, the substrate experiences some forward and backward displacement. The robotic arm is programmed to grip the substrate at a fixed position each time. In extreme cases, this can lead to the gripper protrusions not aligning with the substrate's grooves, resulting in the substrate not being gripped. In most cases, there is friction between the edge of the gripper protrusion and the edge of the substrate groove. This metal-to-metal friction generates metal powder, which accumulates in the substrate groove. During vacuum coating, the substrate rotates at high speed, causing the metal powder in the substrate groove to be ejected and adhere to the surface of the coated product, forming crystal spots and causing product defects. Utility Model Content

[0003] The purpose of this invention is to provide a robotic arm gripper for an automated vacuum coating production line to solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm gripper for an automatic vacuum coating line, comprising a slide rail, on which two slide blocks are slidably mounted, each slide block being mounted with a base, the slide blocks being driven by a cylinder, and gripper arms being mounted at both ends of the base, with pads mounted on the inner side of the gripper arms, the pads being made of polyurethane elastomer.

[0005] Preferably, the pad has a groove on the side away from the claw arm.

[0006] Preferably, the pad and the claw arm are fixed together by countersunk screws.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: Two sliding blocks achieve contraction and expansion through a cylinder slide rail, thereby cooperating with the claw arm and the pad to achieve the purpose of gripping the substrate. The polyurethane elastomer pad is fixed to the claw arm with countersunk screws. The inner side of the pad, where it contacts the substrate, is grooved. This groove has a certain redundancy so that the substrate is completely contained within the groove when the claw grips it, and it also prevents the substrate from detaching from the claw. Since the contact between the pad and the substrate is mostly planar, friction is reduced. Furthermore, since the pad is made of polyurethane elastomer, there are fewer frictional particles generated when it contacts a metal substrate, thus reducing the occurrence of crystal defects.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0013] Please see Figure 1-2 In this embodiment of the present invention, a robotic arm gripper for an automated vacuum coating line includes a slide rail 1. Two slide blocks 4 are slidably mounted on the slide rail 1. The slide blocks 4 are driven by a cylinder 2. Each slide block 4 is equipped with a base 3. Claw arms 5 are mounted at both ends of the base 3. A pad 6 is mounted on the inner side of the claw arm 5. The pad 6 is made of polyurethane elastomer and has a groove on the side away from the claw arm 5. The pad 6 and the claw arm 5 are fixed together by countersunk screws. The two slide blocks expand and contract through the cylinder slide rail, thereby cooperating with the claw arm and the pad to achieve the purpose of gripping the substrate. The polyurethane elastomer pad is fixed to the claw arm by countersunk screws. The part of the pad that contacts the substrate is grooved. The groove has a certain redundancy so that the substrate is fitted into the groove when the gripper grips the substrate, and it also prevents the substrate from falling off the gripper. Since the contact between the pad and the substrate is mostly planar, friction is reduced. In addition, the pad is made of polyurethane elastomer, which generates fewer frictional particles when in contact with the metal substrate, thereby reducing the occurrence of crystal defects.

[0014] The working principle of this invention is as follows: Two sliding blocks expand and contract via a cylinder guide rail, thereby cooperating with the claw arm and pad to grasp the substrate. The polyurethane elastomer pad is fixed to the claw arm with countersunk screws. The inner side of the pad, which contacts the substrate, is grooved with some redundancy, ensuring that the substrate is fully contained within the groove when the claw grasps it, and preventing the substrate from detaching from the claw. Since the contact between the pad and the substrate is mostly planar, friction is reduced. Furthermore, the polyurethane elastomer material of the pad generates fewer frictional particles when in contact with the metal substrate, thus reducing the occurrence of crystal defects.

[0015] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
