[0035] Embodiment:

[0036] Figure 1 It is a structure diagram of the positioning module provided by the utility model embodiment, as shown in Figure 1 The positioning module includes a base 1, a sliding block 2 and a transmission assembly 3.

[0037] The base 1 has a sliding groove 12 arranged along a first direction (X-axis direction), and the sliding block 2 is slidably arranged in the sliding groove 12, and a first elastic member 13 is clamped between the sliding block 2 and the base 1.

[0038] The transmission assembly 3 includes a movable block 31, an unlocking button 32, a locking block 33 and a first connecting rod 341, the movable block 31 is slidably arranged on the base 1 along a second direction, the unlocking button 32 is used to drive the movable block 31 to slide, the locking block 33 is used to lock the unlocking button 32, and the two ends of the first connecting rod 341 are hinged on the sliding block 2 and the movable block 31 respectively, and the first elastic member 13 and the first connecting rod 341 are located on the same side of the sliding block 2 (i.e. both are located on the left side of the sliding block 2).

[0039] Exemplarily, when the connector on the carrier plate needs to be positioned, first, the movable block 31 is driven to slide backward in the second direction by unlocking the button 32. In the process of the backward movement of the movable block 31, the slider 2 is caused to retreat by the first connecting rod 341, and the slider is separated from the through hole of the carrier plate (regarded as the first state, the slider does not support the connector), so as to avoid the interference of the slider 2 with the placement of the connector. In the process of the backward movement of the slider 2, the first elastic member 13 is compressed. Then, the unlocking button 32 is locked by the locking block 33. At this time, the unlocking button 32, the movable block 31, the first connecting rod 341 and the slider 2 are all locked, and the first elastic member 13 cannot drive the slider 2 to move forward to reset.

[0040] Then, the display panel is placed on the carrier plate, the connector of the display panel is inserted into the through hole, and the connector is arranged obliquely in the through hole (at this time, the slider 2 is arranged opposite to the connector, and the unlocking button 32 and the locking block 33 are located outside the screen body). Finally, the locking block 33 is unlocked to unlock the unlocking button 32, so as to finally unlock the movable block 31. At this time, under the action of the first elastic member 13, the slider 2 is automatically moved forward to one end of the sliding groove 12, and at this time, the slider 2 is accurately moved to the target position of one end of the sliding groove 12 under the action of the first elastic member 13 (regarded as the second state, the slider supports the connector), and the side surface of the slider 2 is just attached to the connector and located above the connector at this position, so as to accurately support the connector. Thereafter, the crimping test can be performed, and under the action of the elastic force of the first elastic member 13, the slider is firmly arranged at one end of the sliding groove 12 (the slider will not retreat in the process of crimping).

[0041] In an implementation mode of the utility model, the transmission assembly includes a second connecting rod 342, the movable block 31 is provided with a guide groove 312 arranged in the first direction, the base 1 is provided with a mounting seat 11, the first elastic member 13 is located between the slider 2 and the mounting seat 11, one end of the second connecting rod 342 is hinged to the mounting seat 11, and the other end of the second connecting rod 342 is hinged to the first connecting rod 341 and the hinge shaft is in sliding fit with the guide groove 312. The two connecting rods (i.e. the first connecting rod 341 and the second connecting rod 342) can increase the driving stroke of the slider 2, and the connecting rod slides more smoothly.

[0042] In addition, the movable block 31 is provided with a first inclined surface 311, the unlocking button 32 is slidably arranged on the base 1 to lift relative to the base 1, and the bottom of the unlocking button 32 is abutted against the first inclined surface to drive the movable block 31 to slide. That is, the unlocking button 32 (the unlocking button 32 is located above the movable block 31) is moved in the vertical direction to drive the movable block 31 to slide.

[0043] Further, one side of the unlocking button 32 is provided with a boss 321, and the locking block 33 is slidably arranged on the base 1 in the second direction to limit and lock the boss. The locking block 33 plays a role of limiting the upward movement of the boss 321,

[0044] It should be noted that in other embodiments of the utility model, the unlocking button 32 can be arranged on the side of the movable block, at this time the unlocking button 32 also slides along the second direction, that is, the movable block 31 is driven to slide by sliding along the second direction. In addition, the locking block 33 can also be arranged to be locked by being movably arranged into the corresponding locking groove of the unlocking button 32, and the utility model does not limit this.

[0045] Specifically: Figure 2 is the structural schematic diagram of the transmission assembly provided by the utility model embodiment, Figure 3 is the assembly schematic diagram of the unlocking button provided by the utility model embodiment, in combination with Figure 2 and Figure 3 It is shown that the base 1 has a mounting seat 11, the transmission assembly 3 includes a movable block 31, an unlocking button 32, a locking block 33 and two connecting rods, the movable block 31 is slidably arranged on the base 1 along the second direction (Y-axis direction), the first inclined surface 311 and the guide groove 312 arranged along the first direction are arranged on the movable block 31, one side of the unlocking button 32 has a boss 321, the unlocking button 32 is slidably arranged on the base 1 to lift (Z-axis direction) relative to the base 1, and the bottom of the unlocking button 32 abuts against the first inclined surface 311 to drive the movable block 31 to slide, the locking block 33 is slidably arranged on the base 1 along the second direction to limit and lock the boss 321, one end of one connecting rod is hinged to the mounting seat 11, one end of the other connecting rod is hinged to the sliding block 2, the other ends of the two connecting rods are hinged and the hinge shafts (arranged along the Z-axis) are in sliding fit with the guide groove 312, so that the sliding block 2 is driven to move in the direction away from the mounting seat 11 through the two connecting rods.

[0046] For the positioning module provided by the utility model embodiment, the positioning module is installed on the carrier plate. When it is needed to position the connector on the carrier plate, first, the unlocking button 32 is pressed down, the unlocking button 32 slides down, the bottom of the unlocking button 32 presses the first inclined surface 311 of the movable block 31, the movable block 31 slides backward along the second direction. In the process of the backward movement of the movable block 31, the hinge shafts of the two connecting rods are correspondingly pulled through the guide groove 312, the included angle of the two connecting rods becomes smaller, the other connecting rod correspondingly pulls the sliding block 2 to retreat (that is, moves in the direction of the mounting seat 11, the sliding block 2 moves from one end to the other end of the sliding groove 12), the sliding block 2 retreats and is separated from the through hole of the carrier plate (regarded as the first state, the sliding block does not support the connector), so that the sliding block 2 does not interfere with the placement of the connector. In the process of the backward movement of the sliding block 2, the first elastic member 13 is compressed. Then, the locking block 33 is slid, the locking block 33 moves to the upper side of the boss 321 of the unlocking button 32 to limit. At this time, the unlocking button 32, the movable block 31, the connecting rods and the sliding block 2 are locked, and the first elastic member 13 does not drive the sliding block 2 to move forward to reset.

[0047] In addition, since the sliding directions of the unlocking button 32 and the movable block 31 are different from the direction of the slider 2, and the driving of the slider 2 in the first direction can be converted into the driving of the lateral unlocking button 32 based on the transmission of the connecting rod (that is, the driving position and the driving direction of the unlocking button 32 are changed by the transmission of the connecting rod relative to the direct driving of the slider 2, and the slider 2 can be driven back by only operating the unlocking button 32 on the lateral side of the slider 2, and the locking can be achieved by operating the locking block 33 on the lateral side), convenient recycling operation of the slider 2 can be achieved, the operation of the slider in a narrow space is avoided, and the test efficiency is improved.

[0048] Then, the display panel is placed on the carrier plate, the connector of the display panel is inserted into the through hole, and the connector is arranged obliquely in the through hole (at this time, the slider 2 is arranged opposite to the connector, and the unlocking button 32 and the locking block 33 are located outside the screen body). Finally, the locking block 33 is driven to retreat, the locking block 33 is unlocked from the locking of the boss 321, and thus the movable block 31 is finally unlocked. At this time, under the action of the first elastic member 13, the slider 2 is automatically moved forward to one end of the sliding groove 12, and at this time, the slider 2 is accurately moved to the target position (which is regarded as a second state, the slider supports the connector) of one end of the sliding groove 12 under the action of the first elastic member 13. At this position, the side surface of the slider 2 is just attached to the connector and located above the connector, and accurate support for the connector is achieved. Thereafter, crimping test can be performed, and under the elastic force of the first elastic member 13, the slider is firmly arranged at one end of the sliding groove 12 (the slider will not retreat in the crimping process). In the process of moving the slider 2 forward, the connecting rod and the movable block 31 are reset, so as to prepare for the positioning of the next display panel.

[0049] That is, the positioning module provided in the embodiment of the utility model not only can conveniently drive the slider 2, but also the slider 2 is driven by the first elastic member 13, the transmission error is small, and accurate movement of the slider 2 to the target position is ensured.

[0050] It is easy to understand that when the positioning module is in the first state, the hinged shafts of the two connecting rods are located at one end of the guide groove 312, and when the positioning module is in the second state, the hinged shafts of the two connecting rods are located at the other end of the guide groove 312.

[0051] Exemplarily, the other ends of the two connecting rods are hinged on the pin shaft (that is, the hinged shaft mentioned above), the movable bearing 3121 is inserted into the guide groove 312, and one end of the pin shaft is inserted into the inner ring of the movable bearing 3121, so as to reduce the friction force.

[0052] In addition, in the positioning module, the elastic force of the first elastic member 13 is used to drive the slider 2 to move forward, and the transmission assembly 3 is used to drive the slider 2 to move backward and compress the first elastic member 13. Therefore, when the slider 2 is driven to the target position, the transmission assembly 3 does not need to be actively driven, and the slider 2 can be accurately moved by the first elastic member 13.

[0053] Exemplarily, the side of the slider 2 away from the mounting base 11 is provided with a second inclined surface 22, which is parallel to the connector, so that the connector is better and more stably supported by the second inclined surface 22. When the slider 2 slides to one end of the sliding groove 12, the second inclined surface 22 is parallel to and in contact with the connector.

[0054] Figure 4 is an assembly view of the base provided by the embodiment of the utility model, Figure 5 is a structural view of the base provided by the embodiment of the utility model, which is combined with Figure 4 and Figure 5 As shown in the figures, the base 1 is provided with two spaced-apart limiting grooves 14 corresponding to the side walls of the sliding groove 12, and each limiting groove 14 extends in the first direction. The slider 2 is provided with a protrusion 23 on each of the opposite sides, and each protrusion 23 is in sliding cooperation with the corresponding limiting groove 14.

[0055] In the above embodiment, the limiting groove 14 can limit the slider 2 in the vertical direction, so that the slider 2 does not vertically separate from the sliding groove 12 during sliding.

[0056] Exemplarily, the base 1 is provided with a stepped groove, including three steps, the inner diameter of the lowermost groove is the smallest, which is regarded as the sliding groove 12, and the uppermost groove is the largest, and the pressing strip 19 is inserted into the uppermost groove. The pressing strip 19 can limit the top of the middle groove, thereby forming the limiting groove 14.

[0057] Further, the bottom of the slider 2 is provided with a plurality of spaced-apart guide bearings, and the outer ring of each guide bearing is in sliding cooperation with the corresponding side wall of the sliding groove 12, thereby reducing the frictional force during the sliding of the slider 2.

[0058] It should be noted that the sliding of the movable block 31 also uses the above-mentioned limiting groove limiting and guide bearing guiding, which will not be described here.

[0059] Figure 6 is a structural view of the slider provided by the embodiment of the utility model, as shown in the figure, Figure 6 The base 1 is provided with a first positioning groove 15, and the slider 2 is provided with a second positioning groove 21. The two ends of the first elastic member 13 are respectively inserted into the first positioning groove 15 and the second positioning groove 21, and the positioning of the two ends of the first elastic member 13 is realized by the first positioning groove 15 and the second positioning groove 21.

[0060] Referring to Figure 3 The bottom of the boss 321 has a first inclined surface 3211, and the top of the locking block 33 has a second inclined surface 331. Preferably, the first inclined surface 3211 is parallel to the second inclined surface 331. The first inclined surface 3211 is used to drive the second inclined surface 331 to move in the first direction.

[0061] In the above embodiment, the second inclined surface 331 is extruded by the first inclined surface 3211 during the process that the unlocking button 32 moves downward, so that the locking block 33 can automatically retreat.

[0062] Further, the second elastic member 16 is clamped between the locking block 33 and the base 1.

[0063] It is easy to understand that the second elastic member 16 is extruded by the locking block 33 during the process that the unlocking button 32 moves downward, and the locking block 33 can be automatically driven to extend under the action of the second elastic member 16 when the boss 321 moves below the locking block 33, so that the automatic locking of the boss 321 is realized, and the unlocking button 32 will not be reset upward.

[0064] In an implementation mode of the utility model, the transmission assembly 3 includes a locking button 35, the locking button 35 is slidably arranged on the base 1 to lift relative to the base 1, and the bottom of the locking button 35 is provided with a third inclined surface 351. Preferably, the third inclined surface 351 is parallel to the second inclined surface 331. The third inclined surface 351 is used to drive the second inclined surface 331 to move in the first direction.

[0065] In the above embodiment, the second inclined surface 331 can be driven to move by the third inclined surface 351 during the process that the locking button 35 descends, so that the locking block 33 retreats against the elastic force of the second elastic member 16, so that the locking of the boss 321 by the locking block 33 can also be released. At this time, the slider 2 is driven to move forward by the first elastic member 13 during the process that the slider 2 moves forward, and the slider 2 is finally driven to move forward by the connecting rod transmission, so that the movable block 31 moves forward, the unlocking button 32 resets upward, and the positioning module switches to the second state.

[0066] That is to say, the slider 2 retreats by pressing the unlocking button 32, the connector is unlocked, and the display panel can be freely taken and placed. The locking button 35 can release the limiting of the boss 321, so that the slider 2 moves forward, the connector is positioned, and the crimping can be carried out on this basis.

[0067] Exemplarily, the locking button 35 is also located on one side of the screen body of the display panel, and does not interfere with the screen body during operation. In addition, the third elastic member 18 is also clamped between the locking button 35 and the base 1, so that the locking button 32 can automatically reset upward after unlocking, and interference with the movement of the locking block 33 is avoided.

[0068] Exemplarily, the first elastic member, the second elastic member and the third elastic member can all be springs.

[0069] In the embodiment, the base 1 is provided with a pressing plate 17, the pressing plate 17 is provided with a guide hole, and the unlocking button 32 is slidably inserted in the guide hole. The pressing plate 17 plays a guiding role on the unlocking button 32.

[0070] Exemplarily, the pressing plate 17 can also guide the locking button 35.

[0071] Those skilled in the art can understand that the above description is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
