Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and in particular to a soft silicone adhesive fixture. Background Technology

[0002] In current product designs, to increase the anti-slip performance of products, it is often necessary to attach a soft silicone ring to the bottom of the product's outer shell. This design not only improves the stability of the product but also helps to enhance the user experience.

[0003] Currently, the common method for joining silicone rings involves placing a soft silicone ring on a fixture and then bonding the bottom of the product to the silicone ring by pressing. However, due to the soft nature of the silicone ring, it is prone to deformation, making it difficult for workers to accurately align the silicone ring when placing it, resulting in misalignment and affecting product quality. Secondly, due to the limited space at the bottom of the product, increasing the height of the fixed silicone ring during fixture processing can prevent the bottom of the product from making contact with the silicone ring, thus failing to achieve effective bonding.

[0004] Based on this, in order to optimize the bonding stability of existing silicone rings, we propose a soft silicone jig. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that soft silicone rings are prone to deformation due to their softness, making it difficult for employees to accurately align them when placing them, resulting in misalignment and affecting product quality. Therefore, this invention proposes a soft silicone bonding fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a soft silicone adhesive jig, including:

[0008] Carrier and positioning elements floatingly connected in the carrier;

[0009] The positioning element has a contact portion extending through the carrier plate, the contact portion being used to contact the bottom surface of the product;

[0010] The carrier is provided with a rubber pad that is sleeved on the outside of the contact portion, and the contact portion and the product are also provided with a positioning structure.

[0011] Furthermore, the carrier tray includes a pallet and a base plate;

[0012] The base plate has a movable cavity in the middle, and the end face of the tray has a through hole that communicates with the movable cavity, wherein the tray and the base plate are connected by fasteners.

[0013] Furthermore, the positioning member also includes a limiting portion, which is formed below the contact portion;

[0014] The contact portion slides in the through hole, and the limiting portion slides in the movable cavity and stops below the tray.

[0015] Furthermore, the contact portion has a cylindrical structure, and the limiting portion has a rectangular structure.

[0016] Furthermore, several return springs are placed between the bottom of the limiting part and the inner bottom surface of the movable cavity.

[0017] Furthermore, positioning grooves are provided at the bottom of the limiting part and on the inner bottom surface of the movable cavity, and the two ends of the reset spring are respectively placed between the two opposite positioning grooves.

[0018] Furthermore, the positioning structure is a protrusion formed on the upper surface of the contact portion, and the bottom of the product has a recess that adapts to the protrusion and an annular groove that adapts to the rubber pad.

[0019] The present invention proposes a soft silicone applicator, which has the following advantages: By adopting a floating positioning component design, the positioning component can move back and forth up and down using a return spring, effectively avoiding the disadvantage that the bottom of the product cannot contact the adhesive pad due to the positioning component being too high; at the same time, the addition of a product positioning structure on the positioning component effectively prevents the product from moving during the pasting process, greatly improving the efficiency and stability of applying the adhesive ring to the bottom of the product.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 As one embodiment of this utility model, a soft silicone adhesive bonding fixture is disclosed. Specifically, the fixture includes a carrier plate 1 and a positioning member 2 floatingly connected in the carrier plate 1. Specifically, the floating direction of the positioning member 2 is the height direction of the carrier plate 1.

[0027] The positioning member 2 has a contact portion 20 extending through the carrier plate 1, the contact portion 20 being used to contact the bottom surface of the product 3;

[0028] The carrier plate 1 is provided with a rubber pad 4 that is sleeved on the outside of the contact portion 20. The rubber pad 4 is made of soft silicone and can be coated with an adhesive layer for bonding with the bottom of the product 3. The contact portion 20 and the product 3 are also provided with a positioning structure 5.

[0029] In some embodiments, the carrier 1 of the present invention includes a tray 11 and a base plate 12; the base plate 12 has a movable cavity 13 in the middle, and the end face of the tray 11 is provided with a through hole 14 communicating with the movable cavity 13. The tray 11 and the base plate 12 are connected by fasteners. In a specific embodiment, the fasteners are set as screws, that is, the tray 11 and the base plate 12 in this embodiment are connected and fixed by screws. At the same time, the movable cavity 13 and the through hole 14 form a space for the positioning member 2 to move.

[0030] Based on the above embodiments, the positioning member 2 in this embodiment further includes a limiting part 21, which is formed below the contact part 20. In this embodiment, the limiting part 21 and the contact part 20 are integrally formed.

[0031] The contact portion 20 slides in the through hole 14, and the limiting portion 21 slides in the movable cavity 13 and stops below the tray 11.

[0032] It should be noted that the contact part 20 in this embodiment is a cylindrical structure. Of course, the through hole 14 in this embodiment is set as a circular hole that matches the contact part 20. The limiting part 21 is a rectangular structure, that is, the movable cavity 13 is set as a rectangular cavity that matches the limiting part 21. The design of the limiting part 21 with a rectangular structure is to avoid the entire positioning part 2 from rotating circumferentially, so as to ensure the connection stability between it and the product 3.

[0033] Of course, in order to reset the positioning member 2 after it is pushed down, in this embodiment, a number of reset springs 22 are also placed between the bottom of the limiting part 21 and the inner bottom surface of the movable cavity 13.

[0034] The bottom of the limiting part 21 and the inner bottom surface of the movable cavity 13 are provided with positioning grooves 23. The two ends of the reset spring 22 are respectively placed between the two opposite positioning grooves 23. That is, in this embodiment, the positioning grooves 23 are used to position the ends of the reset spring 22, which can realize the convenient assembly of the reset spring 22 and also avoid the problem of the reset spring 22 shifting after installation.

[0035] It should be noted that, in this embodiment, the positioning structure 5 is a protrusion formed on the upper surface of the contact portion 20, and the bottom of the product 3 has a recess 31 that adapts to the protrusion and an annular groove 32 that adapts to the adhesive pad 4.

[0036] Specifically, the shape of the protrusion in this embodiment can be any shape. When it is cylindrical, at least two protrusions are provided to prevent the product 3 from rotating circumferentially. Of course, the recess 31 can be pre-formed on the bottom of the outer shell of the product 3, or it can be other holes in the outer shell of the product 3, such as screw holes.

[0037] In specific operation, first place the rubber pad 4 on the carrier plate 1, and center and constrain it by the positioning member 2. Then place the product 3 on the positioning member 2. The protrusion on the positioning member 2 corresponds to the recess 31 at the bottom of the product 3 to prevent the product 3 from moving. Since the contact part 20 protrudes above the carrier plate 1 in the initial state, the bottom of the product 3 does not contact the rubber pad 4 at this time.

[0038] Press product 3 downwards, the return spring 22 begins to contract, and the positioning part 2 moves downwards. At this time, the bottom of product 3 contacts and sticks to the adhesive pad 4. After picking up the pasted product 3, the positioning part 2 rises back to its original position, and the soft silicone pasting of the next product 3 continues.

[0039] In summary, by adopting a floating positioning component 2, the present invention utilizes a return spring 22 to achieve reciprocating up-and-down movement, effectively avoiding the disadvantage that the bottom of the product 3 cannot contact the adhesive pad 4 due to the positioning component 2 being too high; at the same time, the addition of a positioning structure 5 for the product 3 on the positioning component 2 effectively prevents the product 3 from moving during the pasting process, greatly improving the efficiency and stability of applying the adhesive ring to the bottom of the product 3.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
