Detailed Implementation

[0020] Example 1, please refer to Figures 1 to 3, which are schematic diagrams of a screen detection positioning fixture and detection production line provided by this utility model. The screen detection positioning fixture includes: a fixture support block A10, a screen positioning block A20, a wire positioning groove A11, a fixture cover plate A30, etc., which are sequentially arranged on the fixture support block A10. It can be imagined that this screen detection positioning fixture also includes other functional components and specific structures, such as electrical connection components, installation structures, etc., which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0021] In this embodiment, the fixture support block A10 is a rectangular block main support structure that provides structural strength for the flow of various processes, and the overall center of gravity is balanced for easy transportation.

[0022] In this embodiment, the screen positioning block A20 is axially detachably connected to one end of the fixture support block A10. The screen positioning block A20 has a screen limiting slot A21 for screen positioning and external protection. Specifically, one end of the fixture support block A10 is connected to a plug-in positioning post A13, and the screen positioning block A20 has a plug-in positioning hole A22 that mates with the plug-in positioning post A13. The plug-in positioning hole A22 on the screen positioning block A20 is sleeved onto the plug-in positioning post A13 along the thickness direction, achieving an axially detachable connection between the screen positioning block A20 and the fixture support block A10. This detachable nature of the screen positioning block A20 allows the fixture to be adapted to different screen sizes, improving its versatility in testing. The screen positioning block A20 is provided with protruding screen guide posts A23 at intervals. The outer surface of the screen guide posts A23 is smooth. A screen guide groove A24 is formed between the screen guide posts A23. Before the screen end is inserted, the screen guide groove A24 can be used as a pre-insertion guide for the screen to be inserted into the screen limiting slot A21, so as to prevent damage caused by inaccurate insertion direction of the screen end and the screen limiting slot A21.

[0023] In other embodiments, the screen positioning block A20 and the clamp support block A10 can also be connected by magnetic attraction or threaded connection.

[0024] In this embodiment, the clamp support block A10 has a recessed wire positioning groove A11, and a port positioning groove A12 communicating with the wire positioning groove A11 is provided at the end of the clamp support block A10 away from the screen limiting slot A21. The port positioning groove A12 is used to position the detection electrical port of the screen wire, and the wire positioning groove A11 is used to position the wire close to the detection electrical port, thus completing the positioning of the two movable ends of the screen, preventing the wire near the detection electrical port from bending and breaking, and improving the positioning accuracy, which is beneficial to the electrical detection of the screen. Optimally, one end of the fixture support block A10 is provided with a recessed fixture step surface A14, and the insertion positioning post A13 is set on the fixture step surface A14, which reduces the interference of the insertion connection between the screen positioning block A20 and the fixture support block A10. At the same time, the height of the screen positioning block A20 is lower than the height of the fixture support block A10, which makes it easier for the wire to extend laterally from the screen end into the wire positioning groove A11. Moreover, the space between the bottom of the screen and the screen positioning block A20 is also conducive to the overall gathering of the excess screen wires extending out of the wire positioning groove A11, saving fixture space.

[0025] In this embodiment, a clamp cover plate A30 is hinged to one side of the clamp support block A10. There are two clamp cover plates A30, each independently hinged. The two clamp cover plates A30 can respectively press against the wire positioning groove A11 and the port positioning groove A12. The multiple clamp cover plates A30 provide better positioning and reduce mutual interference. The clamp cover plate A30 corresponding to the wire positioning groove A11 has a rectangular frame structure, reducing the pressing area with the clamp support block A10 and minimizing damage from foreign object compression. A pressing pad A32 is provided on the clamp cover plate A30 located in the port positioning groove A12. The pressing pad A32 flexibly presses against the port positioning groove A12, preventing damage to the electrical ports of the wire under force and providing elastic fixation of the electrical ports, thus avoiding inaccurate test results due to poor port contact during testing. The clamp cover plate A30 can be fitted with a torsion spring at the hinge to increase stability when open.

[0026] In other embodiments, the clamp cover plate A30 may also be a single cover plate that simultaneously presses onto the wire positioning groove A11 and the port positioning groove A12.

[0027] The clamp cover plate A30 and the clamp support block A10 are fixed together by a pressure plate fixing structure A31. The pressure plate fixing structure A31 includes magnetic blocks A311 respectively disposed on the clamp support block A10 and the clamp cover plate A30. The two magnetic blocks A311 or the magnetic blocks A311 are attracted and fixed to the metal plate. When the clamp cover plate A30 rotates and presses against the wire positioning groove A11, the magnetic blocks A311 attract each other to form a lock between the clamp support block A10 and the clamp cover plate A30 without the action of external force.

[0028] In other embodiments, the pressure plate fixing structure A31 further includes an elastic protrusion A312 disposed on the clamp support block A10, and a rotation limiting part A313 disposed at the end of the clamp cover plate A30 away from the hinge point and cooperating with the elastic protrusion A312. The rotation limiting part A313 can elastically pass through the elastic protrusion A312 or a clearance opening is provided on the rotation limiting part A313 to form a rotationally engaged elastic snap-fit ​​structure. Under the absence of external force, the clamp support block A10 and the clamp cover plate A30 are locked together. This solution can also be used as a supplementary solution to the magnetic block A311 to improve the locking effect and avoid the problem of accidental opening.

[0029] A cover plate opening groove A15 is provided at the movable contact point between the fixture support block A10 and the fixture cover plate A30, away from the hinge point of the two. The cover plate opening groove A15 increases the protruding end area of ​​the fixture cover plate A30 relative to the fixture support block A10. The cover plate opening groove A15 also serves as a force guide groove for opening the fixture cover plate A30 and acting on the fixture cover plate A30, which facilitates automated matching.

[0030] In this embodiment, the clamp support block A10 is provided with a test through hole A16 at one end near the port positioning groove A12, which is connected to the port positioning groove A12. The built-in detection of the electrical port can play a protective role, and the test through hole A16 provides an external electrical connection channel and avoids accidental electrical connection from the outside.

[0031] In addition, the fixture support block A10 is also provided with a fixture positioning hole A17, which facilitates accurate positioning of the fixture during subsequent testing, and a wire clamping hole A18 that passes through the fixture support block A10 and communicates with the wire positioning groove A11. The wire clamping hole A18 is used to accurately clamp the wire when transferring the screen and the wire in the future.

[0032] Example 2: This utility model also provides a testing production line, which has the screen testing and positioning fixture as described above. Except for the screen testing and positioning fixture, the other components are all existing technology or commercially available parts.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
