Detailed implementation manners

[0022] To facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the relevant accompanying drawings.

[0023] A positioning fixture for solving the problem of product misalignment, referring to Figure 1 and Figure 2 , includes a fixture body 10. An accommodation groove 11 for accommodating a display screen 20 is formed on the upper surface of the fixture body 10. The display screen 20 and the backlight on one side thereof are accommodated in the accommodation groove 11. The side of the display screen 20 away from the backlight faces upward, so as to facilitate the bonding operation between the display screen 20 and the solid OCA glue.

[0024] Referring to Figure 1 , a fixed clamping block 30 is provided on one side of the fixture body 10 relative to the display screen 20. The fixed clamping block 30 is fixedly arranged and abuts against the side of a long side of the display screen 20. When the display screen 20 is placed in the accommodation groove 11, one side of the display screen 20 abuts against the fixed block 45. There are two fixed clamping blocks 30, and the two fixed clamping blocks 30 are arranged along the length direction of the accommodation groove 11.

[0025] Further, referring to Figure 1 , an FPC 21 is usually bonded to the display screen 20. Therefore, a relief groove 12 is formed on the upper surface of the fixture body 10 at a position corresponding to the FPC 21. The relief groove 12 is communicated with the accommodation groove 11. When the display screen 20 is accommodated in the accommodation groove 11, the FPC 21 is correspondingly placed in the relief groove 12.

[0026] Referring to Figure 1 and Figure 2, due to the uncertain size of the display screen 20, when the size of the display screen 20 is relatively small, the display screen 20 cannot be fixed on the fixture body 10, which is inconvenient for the bonding operation. Therefore, a moving clamping block 40 is provided on the other side of the fixture body 10 relative to the display screen 20. The moving clamping block 40 is arranged opposite to the fixed clamping block 30. The moving clamping block 40 and the fixed clamping block 30 are respectively located on both sides of the fixture body 10 relative to the accommodation groove 11. The number of the moving clamping blocks 40 and the fixed clamping blocks 30 is adapted. There are two moving clamping blocks 40, and the two moving clamping blocks 40 are arranged along the length direction of the accommodation groove 11. The moving clamping block 40 can be moved to adjust to a suitable position to abut against the other side of the display screen 20 away from the fixed clamping block 30, so as to fix the display screen 20 on the fixture body 10.

[0027] Referring to Figure 1 and Figure 2 , the moving clamping block 40 includes two side blocks 41 and a sliding clamping block 42 slidably arranged between the two side blocks 41. The two side blocks 41 are separated by a certain distance. The sliding clamping block 42 is located between the two side blocks 41. The width of the sliding clamping block 42 is the distance between the two side blocks 41, so as to fix the sliding clamping block 42 between the two side blocks 41. The sliding clamping block 42 can slide along the length direction of the side block 41 to approach the side part of the display screen 20.

[0028] Referring to Figure 1 and Figure 2 , a push rod 43 is inserted through the sliding clamping block 42. The push rod 43 is arranged along the length direction of the sliding clamping block 42. The push rod 43 penetrates through the sliding clamping block 42 along the length direction of the sliding clamping block 42. One end of the push rod 43 is located inside the sliding clamping block 42, and the other end of the push rod 43 passes through the outside of the sliding clamping block 42 and is located outside the fixture body 10. A threaded hole 421 for the push rod 43 to penetrate through is formed in the sliding clamping block 42. The push rod 43 is inserted into the threaded hole 421, and a thread 431 is provided on the outer wall of the push rod 43. The push rod 43 is threadedly connected with the inner wall of the threaded hole 421. By rotating the push rod 43 to push the sliding clamping block 42 to slide along the length direction of the side block 41, the position of the sliding clamping block 42 is adjusted to abut against the side part of the display screen 20, and together with the fixed clamping block 30, the display screen 20 is fixed on the fixture body 10.

[0029] Furthermore, referring to Figure 1 and Figure 2 , a knob 50 for conveniently rotating the push rod 43 is sleeved on the end of the push rod 43 passing through the sliding clamping block 42.

[0030] Furthermore, referring to Figure 1 and Figure 2, the heights of the two side blocks 41 are the same as the height of the sliding block 42. A top block 44 for limiting is provided above the two side blocks 41 and the sliding block 42. The length of the top block 44 is the sum of the widths of the two side blocks 41 and the width of the sliding block 42. The top block 44 is arranged on the top of the sliding block 42 to limit the sliding block 42 and prevent the sliding block 42 from shifting.

[0031] Further, referring to Figure 1 and Figure 2 , a fixing block 45 for fixing the push rod 43 is arranged between the two side blocks 41. The fixing block 45 is arranged in a C shape, and the concave portion of the fixing block 45 faces the area between the two side blocks 41. The fixing block 45 is located on the side of the two side blocks 41 away from the accommodating groove 11. The sides of the fixing block 45 facing the two side blocks 41 are respectively connected to the ends of the two side blocks 41. One end of the push rod 43 away from the sliding block 42 passes through the side of the fixing block 45, and the push rod 43 is threadedly connected to the inside of the fixing block 45. The fixing block 45 is used to limit the position of the push rod 43 to prevent it from shifting when the push rod 43 rotates.

[0032] Referring to Figure 1 and Figure 2 , after the display screen 20 is accommodated in the accommodating groove 11 and one side of the display screen 20 abuts against the fixed block 30, by holding the knob 50 and rotating the push rod 43, the sliding block 42 is pushed towards the direction close to the other side of the display screen 20 until the sliding block 42 abuts against the other side of the display screen 20. The fixed block 30 and the moving block 40 cooperate to fix the display screen 20 on the fixture body 10, thus facilitating the subsequent bonding operation of the solid OCA glue, preventing the display screen 20 and the solid OCA glue from being displaced during the bonding process, and improving the bonding efficiency.

[0033] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
