Description

Technical Field

[0001] The utility model relates to the field of magic hook processing, in particular to a magic hook laser welding fixture. Background Art

[0002] In the existing technology, the connection between magic hook (also commonly known as Velcro or Velcro) and various products mainly relies on sewing or bonding processes. These two connection methods have been widely used in many fields, such as clothing, footwear, outdoor equipment, etc., and they provide convenient and fast connection solutions.

[0003] However, these traditional connection methods have shown their limitations in the application of certain specific materials. Especially when dealing with plastic products, due to the characteristics of plastic materials, the sewing process is often not applicable. Sewing plastic materials is not only difficult to operate, but also may damage the integrity of the material and reduce the durability of the product.

[0004] Although the bonding process can solve the connection problem between non-woven materials such as plastics and magic hooks to a certain extent, this process also has significant defects. At present, the bonding process usually requires pre-adhesion on the surface of the material, followed by hot pressing and lamination using hot pressing equipment. However, the high temperature and pressure during the hot pressing process often cause the hook and hair structure of the magic hook to deform, thereby affecting its bonding performance and reusability. In addition, the gluing and hot pressing process also increase production steps and costs, reducing production efficiency. Utility Model Content

[0005] The utility model aims at solving the challenges faced by the prior art in connecting magic hooks with specific materials (such as plastic products), including the inapplicability of sewing and the deformation of the hook hair in the bonding process.

[0006] A magic hook laser welding fixture is provided, comprising: a base plate, a plurality of fixed guide pillars are installed above the base plate, the fixed guide pillars are sleeved with a movable plate through a linear bearing, a cylinder is arranged above the base plate, the movable end of the cylinder is connected to the movable plate, a lower module is also arranged above the base plate at a position corresponding to the movable plate, a placement groove is provided above the lower module, an opening is provided at a position of the movable plate corresponding to the placement groove, a transparent plate is installed in the opening, and a protrusion is provided at a lower portion of the transparent plate at a position corresponding to the placement groove.

[0007] Optionally, a positioning column is provided at a position of the lower module close to the placement groove, a light shielding plate is detachably provided on the positioning column, and the light shielding plate is provided with an avoidance opening.

[0008] Optionally, a transparent cover is detachably provided on the positioning column.

[0009] Optionally, a fixed plate is also installed on the fixed guide column, and a buffer is installed on the fixed plate. Beneficial Effects

[0010] The utility model provides a magic hook laser welding fixture which is applied to a laser. The material to be bonded and the magic hook are pressed tightly by utilizing the protrusions on a transparent plate. Then, the laser is used to penetrate the transparent plate to melt the contact surface between the magic hook and the material to be bonded, thereby achieving the purpose of bonding the two. Compared with the hot pressing compound in the prior art, the magic hook is not easy to deform, and the performance of the magic hook is maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The following is a detailed description of a specific implementation of a magic hook laser welding fixture of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0017] like Figures 1 to 3As shown, a magic hook laser welding fixture includes a base plate 1, a plurality of fixed guide pillars 2 are installed above the base plate 1, and the fixed guide pillars 2 are connected with a movable plate 3 through a linear bearing, so that the movable plate 3 can slide up and down on the fixed guide pillars 2, a cylinder 4 is arranged above the base plate 1, and the movable end of the cylinder 4 is connected to the movable plate 3, and the cylinder 4 can provide power for the movable plate 3 to slide up and down, and a lower module 5 is also arranged above the base plate 1 at a position corresponding to the movable plate 3, and a placement groove 51 is opened above the lower module 5, and the placement groove 51 is used to place materials to be processed, and an opening 31 is opened at a position of the movable plate 3 corresponding to the placement groove 51, and a transparent plate 6 is installed in the opening 31, and the transparent plate 6 is used to transmit light, and a protrusion 61 is provided at a position corresponding to the placement groove 51 at the lower part of the transparent plate 6, and the protrusion 61 is used to apply pressure during bonding.

[0018] It can be understood that the magic hook laser welding fixture provided by the utility model is applied to the laser. In this embodiment, the material to be bonded and the magic hook are first placed on the placement groove 51, the cylinder 4 drives the movable plate 3 to move downward, and the material to be bonded and the magic hook are pressed tightly by the protrusion 61 on the transparent plate 6, and then the laser is used to penetrate the transparent plate 6 to melt the contact surface between the magic hook and the material to be bonded, so as to achieve the purpose of bonding the two.

[0019] In some embodiments, a positioning column 52 is provided near the placement slot of the lower module, and a light shielding plate 7 is detachably provided on the positioning column 52 , and the light shielding plate 7 is provided with an avoidance opening 71 .

[0020] In this embodiment, after the material to be bonded and the magic hook are placed in the placement groove 51, the light shielding plate 7 is buckled on the positioning column 52. At this time, the light shielding plate 7 covers the material to be bonded, and the magic hook is exposed through the avoidance opening 71. In this way, during processing, light is prevented from irradiating other positions that do not need to be melted, which may cause quality problems.

[0021] In some embodiments, a transparent cover plate 8 is detachably provided on the positioning column 52 .

[0022] In this embodiment, after the light shielding plate 7 is covered on the material to be bonded, the transparent cover plate 8 is buckled on the positioning column 52. At this time, the transparent cover plate 8 covers the magic hook to prevent the movable plate 3 from pushing the magic hook during processing and affecting the accuracy.

[0023] In some embodiments, a fixing plate is also installed on the fixed guide column, and a buffer 9 is installed on the fixing plate.

[0024] In this embodiment, the buffer 9 is used to limit the downward movement distance of the movable plate, so as to ensure that the pressure on the magic hook is not too large and avoid the magic hook from being crushed.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
