Description
Technical Field
[0001] This utility model relates to the field of touch screen deformation detection technology, and more specifically, to a touch screen deformation detection fixture. Background Technology
[0002] Touchscreens are a key input component of modern electronic devices, enabling efficient human-computer interaction by sensing user touches and sending commands to the main processor. To ensure product quality, touchscreens undergo multiple inspection processes at the end of production, with deformation detection being a crucial step. This inspection focuses on identifying structural deformations caused by internal stress, improper assembly, or transportation. Using high-precision sensors and optical methods, it effectively determines whether the product's outer wall is flat and whether the structure is bent, preventing assembly difficulties, display abnormalities, or touch malfunctions caused by deformation at the source. It is a core means of ensuring product yield and durability. Currently, during the phase change detection of touch screens, it has been found that the fixtures for fixing the touch screens have a fixed structure. Each time a different model of touch screen is replaced, a corresponding special fixture must be switched, which leads to a significant increase in production costs and is not conducive to the switching and testing of products. To address the aforementioned issues, this application proposes a touchscreen deformation detection fixture. Utility Model Content
[0003] The purpose of this utility model is to provide a touch screen deformation detection fixture to solve the problem of low applicability of existing touch screen fixtures.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A touch screen deformation detection fixture includes a deformation detector and a detection fixture within its working area; The testing fixture includes a fixed base, a boss, and a side plate that can move laterally. The fixing base is a box structure with an opening at the top. The boss is fixedly installed inside the fixing base. A side groove is provided between the boss and the inner wall of the fixing base, covering the left end and the front and rear ends of the boss. The side plate is located on the outer side of the left end of the fixed seat. The inner side of the side plate is provided with a fixed base plate and a lifting and lowering carrier plate above it. The carrier plate and the base plate are spliced with the boss to fill the side groove. The front and rear sides of the carrier plate and the base plate are symmetrically provided with opposing moving positioning groups; A side baffle is fixed above the left end of the carrier plate.
[0005] Preferably, the worktable of the deformation detector is rotatably mounted with trays at both ends, allowing it to operate horizontally and be stored vertically.
[0006] Preferably, the left and right ends of the fixing base are respectively provided with a feeding groove and a discharging groove, and the top of the discharging groove is located above the boss and adjacent to each other.
[0007] Preferably, an electric telescopic device is provided above the base plate and fixedly connected to the carrier plate, distributed at the corner positions.
[0008] Preferably, the positioning assembly includes a positioning column and a slide, the slide being slidably installed inside positioning grooves opened on the front and rear sides of the carrier plate.
[0009] Preferably, at least two positioning posts are provided in the left and right directions and are installed above the slide, and the slide is located between the base plate and the carrier plate.
[0010] Preferably, a transmission unit is provided on the upper left end of the base plate to drive the carriage to move back and forth in the forward and backward directions.
[0011] The beneficial effects of this utility model are: By moving the positioning columns in opposite directions on both sides inside the side panel, the touch screen can be guided to the central area, enabling simultaneous size adjustment and positioning operations. This adapts to different models of touch screens and meets the deformation detection needs of different product models. By removing and merging the side plate on one side of the fixed base, combined with the lifting and lowering movement of the carrier plate on the base plate, the carrier plate carrying the touch screen can be quickly removed before and after the inspection operation to facilitate positioning and adjustment. At the same time, the inspected touch screen can be automatically ejected to achieve the effect of automatic unloading. Attached Figure Description

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0016] A touch screen deformation detection fixture is designed to improve deformation detection efficiency. By combining the lifting and lowering motion of the carrier plate 231 with the pulling motion of the side plate 23, the carrier plate 231 can be moved to the outside for placing the touch screen, avoiding space limitations and facilitating operation. At the same time, by using the opposing movement of the positioning pins 241 on both sides of the carrier plate 231, the touch screen can be quickly positioned in the center area and the size can be automatically adjusted. Finally, when the carrier plate 231 is pushed into the interior of the fixing seat 21, the detected touch screen can be automatically pushed out to achieve the effect of automatic unloading. In some embodiments, the specific structure of the touchscreen deformation detection fixture is as follows: Figure 1-5 As shown, it includes a deformation detector 1 and a detection fixture 2 above it; Deformation detector 1 is the main body of the deformation detection equipment. A detection head is installed on its top, and a support plate 11 is rotatably installed on both sides of the deformation detector 1. The testing fixture 2 includes a fixed base 21 and a pull-out and movable side plate 23 inside it; Among them, the fixing base 21 is a box with an open top, and a boss 22 is fixed at the center of the front and rear inside. There is a certain distance between the left end of the boss 22 and the left side of the fixing base 21. The right end of the boss 22 extends to the right end of the fixing base 21. Side grooves 211 are formed between the front and rear side walls of the boss 22 and the front and rear inner walls of the fixing base 21, as well as between the left end face of the boss 22 and the left end inner wall of the fixing base 21. Furthermore, the side plate 23 is located on the outer side of the left end of the fixed base 21, and the bottom plate 232 is fixedly installed on the inner side of the side plate 23. The carrier plate 231 is lifted and installed above it. When the bottom plate 232 and the carrier plate 231 are slidably installed inside the fixed base 21, they fill the inside of the side groove 211 and form a splice with the boss 22. It is understandable that when the side panel 23 is pulled outward, the lowering of the carrier plate 231 can leave the tested touch screen above the boss 22. Then, when the side panel 23 pushes the carrier plate 231 into the fixed seat 21 in the opposite direction, the raised carrier plate 231 can automatically push out the left-in touch screen to complete the automatic unloading. It is also understandable that the space outside the removed carrier plate 231 is freed from the restriction of obstacles, making it easier to place the touch screen to be tested; A positioning assembly 24 is provided between the carrier plate 231 and the base plate 232, including a positioning post 241 and a carriage 242; Among them, the positioning post 241 is a cylindrical structure, with its upper end extending upwards and protruding above the carrier plate 231; The carriage 242 is a transverse plate structure that moves back and forth, used to fix two transversely adjacent positioning columns 241. It should be noted that positioning grooves 2311 are provided on both the front and rear sides of the carrier plate 231, each corresponding to a positioning post 241, to provide space for the positioning post 241 to slide forward and backward. It should also be noted that a side baffle 2312 protrudes from the upper left end of the carrier plate 231; Understandably, when the touch screen is placed on top of the carrier plate 231 and one end of it blocks the side block 2312, the positioning post 241 moves closer to the front and rear sides of the carrier plate 231 at the same time, which can drive the touch screen to automatically position itself to the center and achieve the effect of automatic size adaptation.
[0017] like Figure 3-5 As shown, a discharge trough 212 is provided at the right end of the fixed base 21, which connects the side trough 211 and the space above the discharge trough 212. The left end of the fixed base 21 is provided with a feed groove 213, which is connected to the side groove 211 and has the same height as the discharge groove 212; Furthermore, an electric telescopic device 2321 is fixedly installed at the corner area of the base plate 232, with its upper end fixedly connected to the lower end of the carrier plate 231, for controlling the lifting and lowering movement of the carrier plate 231. It should be noted that after the carrier plate 231 moves into the interior of the fixed base 21, the upward movement causes the side baffle 2312 to abut against the top surface of the feed trough 213, which in turn drives the upper surface of the carrier plate 231 to be flush with the upper surface of the boss 22.
[0018] like Figure 4-5 As shown, a transmission unit 243 is fixedly installed on the upper left end of the base plate 232, and ball screws are installed at both ends of the unit, which are rotatably connected to the bearing seats on the upper front and rear ends of the base plate 232. The left end of the carriage 242 is provided with a transmission groove, which is connected to the ball screw drive. It should be noted that the ball screws at the front and rear ends of the transmission unit 243 rotate in opposite directions, which can drive the front and rear slides 242 to move in opposite directions at the same time, that is, to move closer or further away at the same time at the same distance. It is understandable that the opposing movement of adjacent carriages 242 can drive the touch screen to move automatically to the center via the positioning column 241.
[0019] In some publicly available publications, the specific usage methods of touch screen deformation detection fixtures are as follows: S1. After a touch screen deformation detection operation, the carrier plate 231 is lowered by the electric telescopic device 2321 to release the support of the touch screen. Then, the side plate 23 is pulled outward so that the bearing part of the carrier plate 231 is moved to the left side of the fixed seat 21, leaving only a part inside the feed trough 213. S2. At this time, the next touch screen to be tested can be placed directly inside the carrier plate 231, and one end of it can be placed against the side block 2312 to complete the positioning. S3. If it is necessary to replace the touch screen with another model, the transmission unit 243 drives the adjacent front and rear slides 242 to move away simultaneously. Then, the touch screen is placed on the top of the carrier plate 231 and one end of it abuts against the side block 2312. Finally, the transmission unit 243 drives the adjacent positioning posts 241 to move closer to each other, thereby abutting against the touch screen and positioning it in the center position. S4. After the touch screen is positioned, the side plate 23 is pushed back so that the carrier plate 231 enters the fixed seat 21. At the same time, the carrier plate 231 is raised by the side baffle 2312 so that its end can abut against the touch screen placed above the boss 22. As the carrier plate 231 is pushed in, the placed touch screen is pushed out from the discharge slot 212 to achieve automatic unloading.
