Description
Technical Field
[0001] This utility model relates to a backlight testing fixture, specifically a fixture for improving the efficiency of backlight EMR testing. Background Technology
[0002] EMR stands for Electro Magnetic Resonance technology. Touchscreens using this technology are also known as electromagnetic touchscreens. The basic principle is that an electromagnetic pen emits electromagnetic signals that interact with an electromagnetic induction plate behind the display screen. When the pen approaches the touchscreen, the electromagnetic induction plate detects the pen's electromagnetic signal, causing a change in the induction lines beneath it. The X and Y coordinates of the pen are calculated based on this change in magnetic flux. This product is primarily used in electronic devices requiring precise handwriting input and drawing functions, providing users with a more convenient, efficient, and accurate handwriting input and drawing experience.
[0003] In existing test fixtures, the snap-fit connection points for the test cables and adapter cables on the fixture body are designed with full clearance, such as... Figure 1 , 2 As shown. When testing an EMR (Electronic Reinforced Molding) cable, traditional male-female connector testing requires manual connection of the male and female connectors. Specifically, this requires two hands simultaneously: one hand holds the cable with the male connector, and the other holds the cable with the female connector for connection. This testing method presents a significant challenge in aligning the male and female connectors on the bottom of the EMR cable. The main reasons for the problems are: ① The EMR electromagnetic membrane must be lifted to see the connector clips on the back of the membrane. Since the cable on the back of the electromagnetic membrane is connected to the EMR via ACF, pulling on the ACF connection during operation can easily cause defects. Therefore, the EMR cannot be lifted too high to prevent the EMR and EMR cable connection from being torn apart. This requires careful operation and takes a long time. Also, because the alignment is done under the electromagnetic membrane, visual obstruction makes it impossible to see, and the alignment is basically based on feeling. Forcing the snap on if the alignment is inaccurate will damage the connector and cause defects, resulting in a loss of yield. ② The male and female clips are small and have a very dense pin arrangement of 40. ③ During the connection clipping process, the EMR material must not be creased or warped. To avoid creases and warping, the EMR cannot be lifted too high during operation, resulting in limited working space and making bottom clipping connection very difficult. This leads to low testing efficiency and the risk of damaging the male and female clips if the alignment is inaccurate before snapping. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] A fixture for improving backlight EMR testing efficiency includes a fixture body with a placement groove. The placement groove has an ACF slot for placing an ACF and a test cable slot for placing a test cable, and the ACF slot and the test cable slot are connected. The fixture body has a semi-recessed structure corresponding to the position of the adapter cable, and the semi-recessed groove is connected to the test cable slot. The adapter cable is fixed in the semi-recessed groove, and the depth of the semi-recessed groove is equal to or greater than the height of the test cable and the adapter cable after the buckle is connected. An L-shaped limiting wall is provided at the edge of the adapter cable buckle and away from the position of the test cable, or at the edge of the semi-recessed groove and away from the position of the test cable.
[0007] The difference between this solution and existing technologies is that the connection position of the test cable and adapter cable clips has been changed from a fully open space to a semi-recessed groove, and the clips for fixing the adapter cable are fixed on the semi-recessed groove. This changes the alignment method of the test cable and adapter cable clips: after fixing the adapter cable clips, only the EMR test cable clips are needed for movement and alignment. The original two movable clips (test cable clips and adapter cable clips) are reduced to only one movable clip (test cable clip) for alignment, which greatly reduces the alignment difficulty, i.e., the operation difficulty is greatly reduced.
[0008] Preferably, in order to improve the alignment accuracy of the test cable clip and the adapter cable clip and reduce the risk of misalignment, the top surface of the L-shaped limiting barrier is flush with or lower than the bottom surface of the placement groove.
[0009] Preferably, the clip side of the adapter cable is fixed to the semi-submerged tank with glue.
[0010] Compared with the prior art, the present invention has the following advantages:
[0011] 1. This utility model reduces the number of movable clips (test cable clip and adapter cable clip) from two to one by fixing the adapter cable clip. This allows for one-handed connection during wiring, significantly reducing alignment difficulty and ensuring high alignment accuracy. It also reduces the risk of misalignment and minimizes damage to the clip caused by misalignment, thus preventing the EMR electromagnetic test board from being scrapped. This effectively improves work efficiency and product yield.
[0012] 2. It can improve the alignment speed of male and female pins of EMR test cables and adapter cables, thereby improving testing efficiency and achieving the goal of improving production efficiency. Attached Figure Description

[0020] To make the objectives and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0021] like Figure 3 , 4 As shown in Figures 5 and 6, this utility model is a fixture for improving the efficiency of backlight EMR testing. It includes a fixture body 1 with a placement groove 2 for placing an EMR electromagnetic membrane 7. The placement groove 2 has an ACF slot 3 for placing an ACF and a test cable slot 4 for placing a test cable 8. The ACF slot 3 and the test cable slot 4 are connected, and the ACF is connected to the test cable 8. A semi-recessed groove 5 is located on the fixture body 1 corresponding to the position of the adapter cable 9. The semi-recessed groove 5 is connected to the test cable slot 4. The adapter cable 9 is secured to the semi-recessed groove 5 with glue on one side. The depth of the semi-recessed groove 5 is equal to or greater than the height of the test cable 8 and the adapter cable 9 after the snap-fit connection. Preferably, the depth of the semi-recessed groove 5 is equal to the height of the test cable 8 and the adapter cable 9 after the snap-fit connection. An L-shaped limiting barrier 6 is provided at the edge of the clip of the adapter cable 9, away from the test cable 8, or at the edge of the semi-sunken trough 5, away from the test cable 8. The best option is to provide an L-shaped limiting barrier 6 at the edge of the clip of the adapter cable 9.
[0022] In a preferred embodiment, the top surface of the L-shaped limiting barrier 6 is flush with the bottom surface of the placement groove 2.
[0023] During testing, the EMR electromagnetic membrane 7 is placed on the placement slot 2 of this fixture. At this time, the ACF and the test cable 8 are aligned in the ACF slot 3 and the test cable slot 4, respectively. The clip of the test cable 8 corresponds to the position of the semi-submerged slot 5. Since one side of the connecting cable and its clip are fixed in the semi-submerged slot 5, the clip of the test cable 8 corresponds to the clip of the connecting cable. Then, the EMR electromagnetic membrane 7 is slightly lifted, and the clip of the test cable 8 is aligned with the L-shaped limiting wall 6 by one hand. The clip of the test cable 8 is then connected with the clip of the adapter cable 9 to complete the connection operation for testing. This invention utilizes a semi-recessed groove 5 to fix the adapter cable 9 and its clips, reducing the original two movable clips (the test cable 8 clip and the adapter cable 9 clip) to only one movable clip (the test cable 8 clip). During wiring, only one hand is needed to press down the test cable 8 clip to complete the clip connection action, greatly reducing the difficulty of alignment, ensuring high alignment accuracy, reducing the risk of misalignment, and effectively improving work efficiency and product yield.
[0024] The above embodiments are merely specific examples to further illustrate the purpose, technical solution, and beneficial effects of this utility model, and this utility model is not limited thereto. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the disclosure of this utility model are included within the protection scope of this utility model.
