Description

Technical Field

[0001] The present application relates to the technical field of display screen lamination, and in particular to a spring ejector pin for lamination. Background Art

[0002] With the rise of intelligence, the automotive industry is also gradually realizing automotive intelligence. For example, the structure of the car display screen is undoubtedly an important manifestation of automotive intelligence. At present, the bonding of the car display screen requires the use of a bonding jig and the use of optical glue to bond the glass cover. The above bonding method is specifically to place the optical glue in the placement groove in the bonding jig, and place the glass cover on the optical glue. At this time, the spring ejector supports the glass cover so that the glass cover and the optical glue do not contact. Then, the bonding jig, glass cover and optical glue are placed in a vacuum bonding machine as a whole, and a force is applied to the spring ejector so that the spring ejector presses down the glass cover to complete the bonding.

[0003] During the lamination process, spring-loaded ejectors play a crucial role, ensuring that the glass cover and optical adhesive do not come into contact under atmospheric pressure. Furthermore, within the vacuum chamber of the vacuum laminator, the spring-loaded ejectors help bond the glass cover and optical adhesive together, ensuring a bubble-free bond. However, as the number of laminations increases, the spring-loaded ejectors can become stuck during lamination, compromising the lamination quality.

[0004] The spring in the spring ejector in the related art is difficult to replace, and it is not easy to confirm whether the spring in the spring ejector is damaged. If the spring ejector becomes stuck, the entire spring ejector needs to be replaced, which increases the cost of use. Utility Model Content

[0036] With the rise of intelligence, the automotive industry is also gradually realizing automotive intelligence. For example, the structure of the car display screen is undoubtedly an important manifestation of automotive intelligence. At present, the bonding of the car display screen requires the use of a bonding jig and the use of optical glue to bond the glass cover. The above bonding method is specifically to place the optical glue in the placement groove in the bonding jig, and place the glass cover on the optical glue. At this time, the spring ejector supports the glass cover so that the glass cover and the optical glue do not contact. Then, the bonding jig, glass cover and optical glue are placed in a vacuum bonding machine as a whole, and a force is applied to the spring ejector so that the spring ejector presses down the glass cover to complete the bonding.

[0037] During the lamination process, spring-loaded ejectors play a crucial role, ensuring that the glass cover and optical adhesive do not come into contact under atmospheric pressure. Furthermore, within the vacuum chamber of the vacuum laminator, the spring-loaded ejectors help bond the glass cover and optical adhesive together, ensuring a bubble-free bond. However, as the number of laminations increases, the spring-loaded ejectors can become stuck during lamination, compromising the lamination quality.

[0038] The spring in the spring ejector in the related art is difficult to replace, and it is not easy to confirm whether the spring in the spring ejector is damaged. If the spring ejector becomes stuck, the entire spring ejector needs to be replaced, which increases the cost of use.

[0039] For the above questions, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4The embodiment of the present application relates to a spring ejector pin 10 for lamination, comprising a housing 100, a needle head 200, an adjustment seat 300 and a compression spring 400. The needle head 200 and the adjustment seat 300 are respectively arranged at two opposite ends of the housing 100, and the compression spring 400 is arranged between the needle head 200 and the adjustment seat 300, and the opposite ends of the compression spring 400 are respectively in contact with the needle head 200 and the adjustment seat 300.

[0040] The housing 100 has a hollow interior, with a first opening 110 and a second opening 120 at opposite ends, each communicating with the interior. The housing 100 has an inner edge protruding inwardly from the first opening 110. Specifically, the housing 100 has a sleeve structure, with the central axes of the first opening 110 and the second opening 120 coinciding with the central axis of the housing 100.

[0041] The needle 200 includes a connected head 210 and a stopper 220. The stopper 220 is slidably disposed within the housing 100, and the stopper 220 is capable of abutting against the inner edge of the first opening 110. The head 210 is connected to the side of the stopper 220 facing the first opening 110, and the head 210 is capable of extending out of the first opening 110. Specifically, the outer diameter of the head 210 is smaller than the outer diameter of the stopper 220. The housing 100 includes a side wall and an end portion disposed at one end of the side wall. The first opening 110 is disposed at the end portion, and the stopper 220 is capable of abutting against the inner side wall of the end portion. The second opening 120 is disposed at the other end of the side wall.

[0042] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The adjustment seat 300 is detachably connected to the inside of the housing 100 and is located at the second opening 120, and the position of the adjustment seat 300 is adjustable along the extension direction of the housing 100. A sleeve portion 310 is provided at one end of the adjustment seat 300 facing the inside of the housing 100, and the outer diameter of the sleeve portion 310 gradually increases in the direction from the end of the adjustment seat 300 facing the inside of the housing 100 to the end of the adjustment seat 300 facing the outside of the housing 100. One end of the compression spring 400 abuts against the limiting portion 220, and the other end of the compression spring 400 is sleeved on the sleeve portion 310. Specifically, the sleeve portion 310 is a conical structure. The central axis of the adjustment seat 300, the central axis of the needle 200 and the central axis of the housing 100 coincide with each other.

[0043] By detachably attaching the adjustment seat 300 to the housing 100 and positioning it at the second opening 120, the adjustment seat 300 can be removed when inspecting the compression spring 400 in the spring ejector pin for damage or replacing the compression spring 400, thereby reducing the cost of use. By making the position of the adjustment seat 300 adjustable along the extension direction of the housing 100, the compression amount of the compression spring 400 can be adjusted by adjusting the position of the adjustment seat 300 relative to the housing 100, thereby increasing the elastic force of the needle 200. By gradually increasing the outer diameter of the sleeve portion 310 from the end of the adjustment seat 300 facing the inside of the housing 100 toward the end of the adjustment seat 300 facing the outside of the housing 100, the compression spring 400 can be securely installed and prevented from falling off during use. Furthermore, the sleeve portion 310 can accommodate different compression springs 400, allowing selection of a suitable compression spring 400 for glass cover plates of different sizes, thus providing a wide range of applications.

[0044] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 According to some embodiments of the present application, optionally, the hollow inner cavity includes a first accommodating section 130 and a second accommodating section 140, the limiting portion 220 is slidably disposed in the first accommodating section 130, and the adjustment seat 300 is adjustably disposed in the second accommodating section 140.

[0045] Specifically, the outer wall of the limiting portion 220 abuts the inner wall of the first accommodating section 130. The limiting portion 220 is a cylindrical structure and can rotate relative to the first accommodating section 130. It should be noted that the compression spring 400 can apply an elastic force to the limiting portion 220, causing the limiting portion 220 to move toward the first opening 110, thereby extending the head portion 210 out of the first opening 110. When the limiting portion 220 moves to abut the inner wall of the end portion, the head portion 210 extends the maximum distance out of the first opening 110.

[0046] In this embodiment, the outer wall of the adjustment base 300 is provided with a first thread, and the inner wall of the second accommodating section 140 is provided with a second thread, and the first thread and the second thread are threadedly connected. By rotating the adjustment base 300, the position of the adjustment base 300 relative to the housing 100 can be adjusted, and the adjustment base 300 can be removed.

[0047] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4According to some embodiments of the present application, optionally, an adjustment portion 320 is provided at one end of the adjustment seat 300 away from the sleeve portion 310. In one embodiment, the adjustment portion 320 is a countersunk hole or a blind hole opened on the end of the adjustment seat 300 away from the sleeve portion 310.

[0048] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 According to some embodiments of the present application, optionally, the inner diameter of the first accommodating section 130 is larger than the inner diameter of the second accommodating section 140, and can be adapted to compression springs 400 with different compression amounts.

[0049] The inner diameter of the first opening 110 is smaller than the inner diameter of the first accommodating section 130 , which can prevent the limiting portion 220 from sliding out of the first opening 110 .

[0050] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 According to some embodiments of the present application, optionally, the head 210 is made of PEEK. Specifically, the limiting portion 220 is made of PEEK.

[0051] It should be noted that PEEK has very high strength and modulus, with a tensile strength exceeding 90-100 MPa and a flexural strength exceeding 170 MPa, enabling it to withstand large external forces without deformation. PEEK also exhibits excellent toughness and high impact strength, resisting fractures when impacted. PEEK can withstand repeated loading and unloading cycles without fatigue failure, and after multiple stress cycles, its material properties show relatively little degradation, making it suitable for components requiring long-term stable operation. PEEK can operate at relatively high temperatures for long periods of time, with a heat deformation temperature typically around 160-180°C. It can withstand higher temperatures for short periods of time. PEEK exhibits excellent resistance to most chemicals. It resists corrosion from acids, alkalis, organic solvents, and other agents, enabling long-term stable operation in some harsh chemical environments.

[0052] The head 210 is made of PEEK material, which has the characteristics of high strength and modulus, excellent toughness, wear resistance, high temperature resistance, and chemical inertness.

[0053] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4According to some embodiments of the present application, the limiting portion 220 and the head portion 210 are optionally integrally formed to ensure the connection strength between the limiting portion 220 and the head portion 210. The adjusting seat 300 and the sleeve portion 310 are integrally formed to ensure the connection strength between the adjusting seat 300 and the sleeve portion 310.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
