Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to a touch screen anti-mis-touch test fixture. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through the LCD display.

[0003] During the production and preparation process, touch screens usually need to pass quality inspection tests before entering the subsequent finished product assembly steps. Some touch screen products will be calibrated synchronously during the quality inspection test. In the actual calibration process, since the touch surface of the touch screen is mostly exposed to the outside, the operator's hands and external wire objects can easily come into contact with the touch screen during the detection process, resulting in abnormal calibration data, which in turn affects the normal operation of the subsequent whole machine. For this reason, a touch screen anti-mistouch test fixture is proposed. Utility Model Content

[0004] Based on this, it is necessary to provide a touch screen anti-mistouch test fixture to address the above technical problems, and to add protective elements above the detection base to form a blocking protection for the touch screen during the detection process, thereby avoiding external contact interference and improving the yield rate of the touch screen.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A touch screen anti-mistouch test fixture, comprising:

[0007] A detection base, wherein an embedding groove is provided on the top of the detection base;

[0008] A touch screen is embedded in the detection base through an embedding groove to be detected;

[0009] The flipping piece is arranged on one side of the top of the detection base and is used for connecting the protective element. The protective element is rotated on the surface of the flipping piece to form a covering protection for the touch screen during detection.

[0011] Furthermore, a connecting block is fixedly connected to the surface of the rotating shaft for connecting it with a corresponding protective element.

[0012] Furthermore, the protection element includes a protection cover plate connected to the corresponding connection block.

[0013] Furthermore, a boss is extended outwardly from the edge of the protective cover plate, and a hollow groove is formed inside the protective cover plate;

[0014] There is a height gap between the empty groove and the touch screen.

[0015] Furthermore, a through slot is provided on the other side of the top of the detection base, and a locking piece is installed in the through slot for locking the flipping of the protective element.

[0016] Furthermore, the locking member comprises a housing fixed in the slot and an arc-shaped clamping block slidably disposed in the housing;

[0017] The side wall of the shell is connected with a spring fixed to the end of the arc-shaped clamping block, and the front end of the arc-shaped clamping block is extended outside the shell by the support of the spring;

[0018] A pushing handle connected with the inner arc-shaped clamping block is slidably disposed on the outer side of the shell.

[0019] Furthermore, a support block is fixed below the boss, and a locking rod is fixedly connected to the surface of the support block.

[0020] Furthermore, a torsion spring is sleeved on the surface of the rotating shaft;

[0021] One end of the torsion spring is connected to the support seat and the other end is connected to the connecting block.

[0022] Furthermore, avoidance grooves are provided at the four corners of the top of the detection base, and insulating protective cotton is laid in the avoidance grooves.

[0040] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0041] As described in the background art, during the detection process, the operator's hands and external wire objects can easily come into contact with the touch screen, causing abnormal calibration data, thereby affecting the subsequent normal operation of the entire machine.

[0042] In order to solve this technical problem, the utility model provides a touch screen anti-mistouch test fixture, which is used for touch screen detection and calibration.

[0043] Specifically, please refer to Figure 1-Figure 8 , the touch screen anti-mistouch test fixture includes:

[0044] A detection base 1, wherein an embedding groove 11 is provided on the top of the detection base 1;

[0045] A touch screen 12, which is embedded in the detection base 1 through the embedding groove 11 to be detected;

[0046] The flip member 3 is disposed on one side of the top of the detection base 1 and is used for connecting the protection element 4. The protection element 4 is rotated on the surface of the flip member 3 to form a covering protection for the touch screen during detection.

[0047] The touch screen anti-mistouch test fixture provided by the utility model connects the protection element 4 on the flip part 3, so that when the touch screen 12 is placed in the embedding groove 11 for testing, the protection element 4 is flipped so that the protection cover plate 41 inside covers the top of the touch screen 12 to form a blocking protection for it, thereby avoiding external interference and ensuring accurate proofreading of data.

[0048] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0051] Please refer to Figure 1-Figure 4 A touch screen anti-mistouch test fixture comprises: a detection base 1, on the top of which is provided an embedding groove 11; a touch screen 12, which is embedded in the detection base 1 through the embedding groove 11 to be detected; a flip member 3, which is arranged on one side of the top of the detection base 1 for connecting with a protective element 4, and the protective element 4 is rotated on the surface of the flip member 3 to form a covering protection for the touch screen during detection.

[0052] Please refer to Figure 3 , Figure 4 The flip member 3 includes a support seat 31 and a rotation shaft 32 rotatably disposed at both ends of the support seat 31;

[0053] A connection block 33 is fixedly connected to the surface of the rotating shaft 32 for connecting it with the corresponding protective element 4;

[0054] Before testing the touch screen 12, the protective cover 41 is turned over to make it appear as shown in the figure. Figure 3 In the state shown, the touch screen 12 is then inserted into the corresponding detection base 1 through the embedding groove 11, and then the protective cover 41 is flipped over so that the connecting block 33 thereon drives the rotating shaft 32 to rotate relative to the support base 31, so that the protective cover 41 covers the top of the detection base 1. After the flipped protective cover 41 contacts the surface of the detection base 1, the touch screen 12 is placed under the protective cover 41, thereby forming protection for the touch screen 12 and avoiding contact with the outside during the detection and calibration of the touch screen 12 to affect the subsequent accuracy.

[0055] The touch screen anti-mistouch test fixture provided in Example 1 is further optimized. Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protection element 4 includes a protection cover plate 41 connected to the corresponding connection block 33;

[0056] A boss 42 extends outward from the edge of the protective cover plate 41, and a hollow groove 43 is formed inside the protective cover plate 41;

[0057] The arrangement of the boss 42 extending from the edge of the protective cover 41 allows the operator to have more space for the hand to contact the protective element 4 when turning over the protective cover 41, thereby facilitating the touch screen 12 to detect the front and back turning;

[0058] There is a height gap between the empty slot 43 and the touch screen 12;

[0059] Through the design of the above structure: Figure 1 and Figure 2As shown, when the touch screen 12 is detected in the embedded groove 11, the flipped protective cover plate 41 can maintain a certain distance from the touch screen 12 below, and the contact between the flipped protective cover plate 41 and the touch screen 12 is avoided by this distance, so that the touch area of ​​the touch screen 12 remains completely protected.

[0060] The touch screen anti-mistouch test fixture provided in Example 1 or 2 is further optimized, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a through slot 13 is provided on the other side of the top of the detection base 1, and a locking member 5 is installed in the through slot 13 for locking the protective element 4 in a flipping state;

[0061] The locking member 5 includes a housing 51 fixed in the through slot 13 and an arc-shaped block 52 slidably disposed in the housing 51;

[0062] The side wall of the housing 51 is connected with a spring 53 fixed to the end of the arc-shaped block 52. The front end of the arc-shaped block 52 is extended outside the housing 51 by the support of the spring 53.

[0063] A support block 420 is fixed below the boss 42, and a locking rod 421 is fixedly connected to the surface of the support block 420;

[0064] On the basis of the above embodiment, in order to keep the flipped protective cover 41 stable when the touch screen 12 is detected, so that it is not easy to be opened from the outside, the locking member 5 is additionally provided;

[0065] Specifically, when the protective cover 41 is flipped over the surface of the detection base 1, the locking rod 421 on the protective cover 41 during the flipping process will come into conflict with the surface of the arc-shaped block 52. Due to the setting of the arc surface structure at the front end of the arc-shaped block 52, it will have a sliding tendency toward the shell 51 when it is subjected to the resistance force. When the arc-shaped block 52 continuously slides in the shell 51, the spring 53 in the shell 51 is also continuously compressed. When the sliding distance of the arc-shaped block 52 is enough for the locking rod 421 to pass through, the protective cover 41 can be further flipped to achieve contact with the detection base 1.

[0066] When the protective cover 41 is completely in contact with the detection base 1, the locking rod 421 is located below the arc block 52, and the arc block 52 does not receive the resistance force of the locking rod 421. At this time, the arc block 52 is popped outward by the force of the spring 53. The arc block 52 after popping out will extend above the locking rod 421 to form a barrier to the locking rod 421. At this time, the protective cover 41 is limited, which ensures the stability of the detection space of the touch screen 12 in the embedded groove 11 and further reduces the possibility of external interference with its contact.

[0067] As a further optimization of this embodiment: the outer side of the housing 51 is slidably provided with a push handle 54 connected to the inner arc-shaped block 52 thereof;

[0068] like Figure 7 As shown, through the structural design of the pushing handle 54, after the detection of the touch screen 12 in the detection base 1 is completed, the pushing handle 54 can be directly pushed to make the arc-shaped block 52 connected thereto slide toward the direction of the shell 51, so that the locking rod 421 can follow the protective cover plate 41 to flip and reset, which is convenient for removing the touch screen 12 in the embedded groove 11 after the detection is completed, so that the subsequent touch screen 12 to be detected can be placed.

[0069] The touch screen anti-mistouch test fixture provided in Example 3 is further optimized, such as Figure 1 As shown, a torsion spring 34 is sleeved on the surface of the rotating shaft 32;

[0070] One end of the torsion spring 34 is connected to the support seat 31 and the other end is connected to the connecting block 33;

[0071] In Example 3, after the touch screen 12 embedded in the groove 11 is detected, when the push handle 54 is pushed to flip the protective cover 41, the protective cover 41 still needs to be manually flipped open by the operator, which is likely to affect the detection efficiency of the touch screen 12. For this reason, the torsion spring 34 is designed;

[0072] Specifically, Figure 8 As shown, when the torsion spring 34 is added, the protective cover plate 41 is subjected to the force of the torsion spring 34. Figure 3 In the open state shown, after the touch screen 12 is placed in the embedded groove 11 and the protective cover 41 is flipped over for closed protection detection, the push handle 54 is pushed to release the limiting effect on the locking rod 421. At this time, through the torsion recovery effect of the torsion spring 34, the protective cover 41 can be rotated and flipped open, thereby making it more convenient for the operator to take out the touch screen 12 in the embedded groove 11, which is beneficial to improving the detection efficiency of the touch screen 12.

[0073] The touch screen anti-mistouch test fixture provided in Example 4 is further optimized, such as Figure 3As shown, avoidance grooves 14 are provided at the four corners of the top of the detection base 1, and insulating protective cotton 15 is laid in the avoidance grooves 14;

[0074] By setting the avoidance groove 14, when the touch screen 12 is placed in the embedding groove 11, the edge of the touch screen 12 can form a better avoidance with the detection base 1, avoiding the corners of the touch screen 12 from making rigid contact with the detection base and being easily broken, which is beneficial to the protection of the touch screen 12 during the detection process.

[0075] The use process of the touch screen anti-mistouch test fixture provided by the utility model is as follows: the touch screen 12 to be tested is placed in the embedding groove 11, the protective cover plate 41 is turned over so that the locking rod 421 on it is placed under the arc-shaped card block 52 to lock the protective cover plate 41, and then the touch screen 12 is tested and proofread through the testing base 1. After the detection and proofreading of the touch screen 12 is completed, the pushing handle 54 is pushed to make the arc-shaped card block 52 release the locking effect of the locking rod 421, and the protective cover plate 41 is turned over and opened by the force of the torsion spring 34, and the touch screen 12 after the detection in the embedding groove 11 is taken out.
