Abstract

This utility model relates to the field of workpiece transfer accessories technology, and specifically discloses an anti-stick plate, including a substrate and multiple protrusions on the substrate. The multiple protrusions are integrally connected to the substrate, and the substrate and protrusions are made of a polymer elastic material. The protrusions are used to contact the workpiece. In the above solution, the anti-stick plate made of polymer elastic material has a low surface energy, that is, the polymer elastic material itself has a certain degree of non-stickiness, which can prevent the adhesive residue on the workpiece from sticking to the anti-stick plate. The multiple protrusions designed on the substrate can further reduce the contact area between the workpiece and the anti-stick plate. The smaller the contact area, the smaller the adhesion force. This design significantly reduces the adhesion force between the workpiece and the anti-stick plate, thereby more effectively preventing the adhesion phenomenon and improving the smoothness of workpiece transfer during the production process.

Description

Technical Field

[0001] This utility model relates to the field of workpiece transfer accessories, and in particular to an anti-stick plate. Background Technology

[0002] In the automated bonding process of mobile phone antennas, the metal antenna needs to be peeled off from the film carrier tape and then transferred through an intermediate transfer stage before being precisely positioned and bonded to the mobile phone casing. During the intermediate transfer stage, a gripping fixture with a vision positioning module can accurately grip the antenna, so that the antenna is bonded to the mobile phone casing in a relatively definite posture and angle.

[0003] However, the lack of a dedicated carrier device for antenna transport in the existing technology leads to the following technical defects in actual production: First, the existing antenna transport generally uses a carrier plate made of metal or engineering plastic with a continuous smooth surface. However, the antenna is prone to displacement due to mechanical vibration or airflow disturbance during transport, which causes the gripping jig to disturb the antenna during the gripping process, resulting in inaccurate gripping posture. Second, the antenna and the thin film carrier tape are glued together. When the antenna is transported to the carrier plate, the antenna is prone to sticking to the carrier plate due to residual adhesive, which increases the difficulty of gripping by the gripping jig.

[0004] Therefore, providing an anti-stick plate to improve the accuracy and efficiency of antenna grabbing is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses an anti-sticking plate to solve the above-mentioned technical problems existing in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] This application provides an anti-stick plate, including a substrate and a plurality of protrusions disposed on the substrate. The plurality of protrusions are integrally connected to the substrate, and the substrate and the protrusions are made of a polymer elastic material. The protrusions are used to contact the workpiece.

[0008] Optionally, a plurality of the protrusion arrays are formed on the substrate, and the plurality of protrusions are spaced apart on the substrate.

[0009] Optionally, the substrate is provided with a first array of protrusions and a second array of protrusions that are alternately distributed along a first direction. Both the first array of protrusions and the second array of protrusions include a plurality of protrusions that are spaced apart along a second direction. The protrusions in the first array of protrusions and the protrusions in the second array of protrusions are staggered in the second direction, and the first direction is perpendicular to the second direction.

[0010] Furthermore, the protrusion is a spherical structure, and the top of the spherical structure is used to contact the workpiece.

[0011] Furthermore, the protrusion includes a base and a contact portion connected to the base, wherein the base is a conical structure, the contact portion is a spherical structure, the large end of the base is connected to the base body, the small end of the base is connected to the contact portion, and the contact portion is used to contact the workpiece.

[0012] Furthermore, in the first array protrusion and the second array protrusion, the distance between two adjacent protrusions is less than the radial dimension of the protrusion.

[0013] Furthermore, the spacing between adjacent first array protrusions and second array protrusions is less than the radial dimension of the protrusions.

[0014] Furthermore, the tops of the plurality of protrusions are located on the same plane.

[0015] Furthermore, the substrate has a plate-like structure, and the thickness of the substrate is greater than the height of the protrusion.

[0016] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0017] The anti-stick plate of this application, made of a polymer elastic material, has a low surface energy, meaning the polymer elastic material itself has a certain degree of non-stickiness, which can prevent residual adhesive on the workpiece from sticking to the anti-stick plate. Multiple protrusions designed on the substrate further reduce the contact area between the workpiece and the anti-stick plate. The smaller the contact area, the weaker the adhesion force. This design significantly reduces the adhesion force between the workpiece and the anti-stick plate, thus more effectively preventing adhesion and improving the smoothness of workpiece transfer during production. At the same time, the integral molding of the substrate and protrusions simplifies the manufacturing process, and the entire anti-stick plate has better structural stability, ensuring the reliability of the anti-stick plate's performance during use and extending its service life.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following is in conjunction with the appendix Figures 1-4 The anti-stick plate provided in this application will be described in detail through specific embodiments and application scenarios.

[0028] Please see Figure 1 and Figure 4 This application discloses an anti-stick plate, which can temporarily support a workpiece (e.g., a metal antenna) during transit, facilitating further processing (e.g., bending the metal antenna) and allowing for precise gripping by a jig to subsequent workstations (e.g., gripping the metal antenna and attaching it to a mobile phone casing). This process effectively prevents adhesion between the workpiece and the anti-stick plate, improving the accuracy and convenience of the gripping jig. For details, please refer to... Figure 1 and Figure 3The disclosed anti-stick plate includes a substrate 100 and a plurality of protrusions 200 disposed on the substrate 100. The plurality of protrusions 200 are integrally connected with the substrate 100, and the substrate 100 and the protrusions 200 are made of a polymer elastic material. Exemplarily, the substrate 100 is a plate-like structure, and the plurality of protrusions 200 are formed on one side of the surface of the substrate 100. The substrate 100 and the protrusions 200 are integrally molded using silicone material. The protrusions 200 can be dot-shaped protrusions, cylindrical protrusions, prismatic protrusions, or spherical protrusions, etc. The embodiments of this application do not impose specific limitations on this. The protrusions 200 are used to contact the workpiece.

[0029] Based on the above technical solutions, in specific applications, the anti-stick plate of this application embodiment has a low surface energy due to the high surface energy of the polymer elastic material (e.g., silicone material). This means that the polymer elastic material itself has a certain degree of non-stickiness, which can prevent the workpiece from sticking to the anti-stick plate. Even if there is adhesive residue on the workpiece, the multiple protrusions 200 designed on the substrate 100 can further reduce the contact area between the workpiece and the anti-stick plate. The smaller the contact area, the smaller the adhesion force. This design significantly reduces the adhesion force between the workpiece and the anti-stick plate, thereby more effectively preventing the adhesion phenomenon and improving the smoothness of workpiece transfer during the production process. At the same time, the integral molding of the substrate 100 and the protrusions 200 can simplify the production process during manufacturing. In addition, the entire anti-stick plate has better structural stability, which can ensure the reliability of the anti-stick plate's performance during use and extend its service life.

[0030] In some embodiments of this application, a plurality of protrusions 200 may be arrayed on the substrate 100, and the plurality of protrusions 200 are spaced apart on the substrate 100. The array arrangement makes the protrusions 200 distributed more evenly on the substrate 100. This even distribution prevents the anti-stick plate from concentrating local stress when bearing the workpiece, preventing excessive pressure at a certain point or in a certain area, and improving the stability and reliability of the anti-stick.

[0031] In some embodiments of this application, please refer to... Figure 1 , Figure 2 , Figure 3 The substrate 100 is provided with a first array of protrusions a and a second array of protrusions b alternately distributed along a first direction. For example, in... Figure 2 In the diagram, the odd-numbered columns of protrusions 200 from right to left constitute the first array protrusions a, and the even-numbered columns of protrusions 200 from right to left constitute the second array protrusions b. Both the first array protrusions a and the second array protrusions b include multiple protrusions 200 spaced apart along a second direction. The protrusions 200 in the first array protrusions a and the protrusions 200 in the second array protrusions b are staggered along the second direction, which is perpendicular to the second direction. For example, the substrate 100 can be a plate-like structure, and the first direction can be the length direction of the substrate 100, i.e., the... Figure 4 The first direction is the X-axis direction, and the second direction can be the width direction of the base 100, that is... Figure 4 In the Y-axis direction; during long-term use, the anti-stick plate will be constantly subjected to contact and friction with the workpiece, which is prone to fatigue damage, such as wear, breakage and detachment of the protrusions 200. In this embodiment, the multiple protrusions 200 are not simply distributed in an array. The protrusions 200 in the first array protrusion a are misaligned with the protrusions 200 in the second array protrusion b. This misaligned distribution makes the stress distribution more uniform, reduces the repeated action of stress cycles on specific parts, thereby reducing the possibility of fatigue crack generation and propagation, extending the service life of the anti-stick plate, and improving its reliability and durability. On the other hand, this misaligned form also allows the protrusions 200 in the second array protrusion b to encroach on the area between two adjacent protrusions 200 in the first array protrusion a, that is, to make the protrusions 200 more densely distributed on the base 100, which can ensure the support stability of the anti-stick plate for the workpiece and avoid the situation where the workpiece and the base 100 are in large-area contact due to the sparse distribution of local protrusions, resulting in poor anti-sticking effect.

[0032] In this embodiment, the protrusion 200 can be a spherical structure. The top of the spherical structure is used to contact the workpiece. Geometrically, the contact between the sphere and the workpiece surface is a point contact. Compared with other shapes of protrusions, such as cylindrical or prismatic protrusions, the spherical structure can control the contact area to a very small range, thereby significantly reducing the adhesion force and more effectively preventing the workpiece from sticking to the anti-stick plate, greatly improving the anti-stick effect. At the same time, the spherical protrusion 200 has high symmetry and uniformity, and can better withstand forces in all directions when subjected to external forces, and is not easily deformed or damaged.

[0033] For further technical solutions, please refer to Figure 3 and Figure 4 The protrusion 200 includes a base 210 and a contact portion 220 connecting the base 210. The base 210 has a conical structure, and the contact portion 220 has a spherical structure. The large end of the base 210 is connected to the base 100, and the small end of the base 210 is connected to the contact portion 220. The contact portion 220 is used to contact the workpiece. The conical base 210 has high stability. Its large end is connected to the base 100, and its small end is connected to the spherical contact portion 220, which can strengthen the strength of the connection between the protrusion 200 and the base 210. This design, which is narrow at the top and wide at the bottom, allows the protrusion 200 to distribute the stress evenly along the conical side to the base 100 when subjected to external force. This enhances the stability of the integral connection between the protrusion 200 and the base 100 and reduces the risk of structural damage caused by local stress concentration. For example, it avoids the risk of the protrusion 200 breaking from its root.

[0034] In this embodiment, the tops of the multiple protrusions 200 are located on the same plane, which enables the workpiece to have a consistent contact state with each protrusion 200. That is, the tops of the multiple protrusions 200 together form a regular support plane, providing a clear positioning reference for the placement of the workpiece and facilitating the positioning and gripping of the gripping fixture.

[0035] In this embodiment, in the first array protrusion a and the second array protrusion b, the distance between two adjacent protrusions 200 is less than the radial dimension of the protrusion 200. This allows the multiple protrusions 200 in the first array protrusion a and the multiple protrusions 200 in the second array protrusion b to be arranged compactly in the second direction. Similarly, the distance between adjacent first array protrusion a and second array protrusion b is less than the radial dimension of the protrusion 200. This allows the protrusions 200 to be distributed compactly in the first direction. Through this design, the multiple protrusions 200 can be distributed relatively compactly in both the first and second directions, thereby ensuring the stability of the workpiece support.

[0036] In this embodiment, the substrate 100 can be a plate-like structure, and the thickness of the substrate 100 is greater than the height of the protrusion 200, so that the substrate 100 has sufficient strength and rigidity to maintain the shape and position of the protrusion 200. During long-term use, the protrusion 200 will not tilt or shift due to the deformation of the substrate 100, thereby ensuring a stable contact state between the protrusion 200 and the workpiece, and a durable and reliable anti-sticking effect.

[0037] In this embodiment, the substrate 100 and the protrusion 200 are structural components made of silicone material. Silicone material itself is soft and elastic. During the process of the gripping fixture gripping the workpiece, a certain impact force may be generated between the gripping fixture and the workpiece. The soft silicone structural component can absorb and disperse this impact force, preventing the workpiece from being damaged due to excessive pressure. On the other hand, the anti-stick plate made of silicone material has the characteristics of being slightly white and transparent. It can serve as a base to facilitate the vision system on the gripping fixture to accurately identify the position and posture of the workpiece, ensuring that the gripping fixture can accurately position and grip the workpiece.
