[0031] Example:

[0032] Figure 1 This is a first view of a crimping mechanism provided in an embodiment of the present invention. Figure 2 This is a second view of a crimping mechanism provided in an embodiment of the present invention, combined with... Figure 1 and Figure 2 As shown, the crimping mechanism includes a base 1, a conductive module 2, and a locking block 3.

[0033] Figure 3 This is a cross-sectional view along direction AA on the base provided in this embodiment of the utility model, as shown below. Figure 3 As shown, the base 1 has a guide hole 11 extending along the first direction (Z-axis direction), the conductive module 2 is provided with a conductive connector 4, the conductive module 2 is slidably inserted into the guide hole 11, and the locking block 3 is slidably inserted into the base 1 along the second direction (Y-axis direction). The locking block 3 is used to insert into the guide hole 11 to support and lock the conductive module 2 in the first direction after the conductive module 2 slides into place.

[0034] For the crimping mechanism provided in this embodiment of the utility model, when crimping and connecting a display panel on a carrier plate or test bench (taking the connector facing downwards as an example), firstly, the base 1 is fixed on the carrier plate, ensuring that the guide hole 11 is perpendicular to the connector. At this time, the crimping mechanism is located below the display panel. Then, the connecting module 2 is driven to move upwards (by pressing with a finger). During the upward movement of the connecting module 2, the connecting connector 4 is moved, facilitating the crimping and connecting of the connector of the display panel (the connecting connector 4 moves perpendicular to the connector). The connecting module 2 moves (upwards) into position, meaning it moves above the locking block 3. Next, the locking block 3 is slid, so that one end of the locking block 3 extends into the guide hole 11. At this time, the locking block 3 provides support for the lower part of the connecting module 2 (preventing the connecting module 2 from moving downwards under the action of gravity), thus locking the connecting module 2 and ensuring that the connector of the connecting connector 4 and the connector of the display panel are always in a crimped state. Since the entire crimping mechanism does not require the use of a cylinder or flipping for crimping during the crimping and connecting process, the testing cost is reduced.

[0035] That is, the crimping mechanism provided by the embodiment of the utility model, simple structure, can conveniently crimp the connector of the display panel, and does not need to be crimped through the cylinder or overturning, thereby reducing the test cost.

[0036] It is easy to understand that after the crimping test is completed, the locking block 3 is slid in the direction away from the guide hole 11, thereby releasing the locking of the conduction module 2, and the conduction module 2 is moved downward, thereby finally contacting the crimping of the connector of the display panel by the conduction connector 4, at this time, the display panel can be removed, and the crimping of the next display panel is prepared.

[0037] In addition, the crimping mechanism only needs to be inserted at the bottom of the carrier plate, without the need to greatly change the structure of the carrier plate itself, that is, the universal crimping can be realized on each corresponding carrier plate, thereby reducing the production cost.

[0038] It should be noted that the crimping mechanism can not only be applied to the working condition that the connector is arranged downward (especially suitable for the working condition that the connector is arranged downward and inclined), but also can be applied to the working condition that the connector is arranged upward, and the utility model does not limit this.

[0039] In the embodiment, the conduction module 2 includes a floating plate 21, a button plate 22 and a first elastic member 23, the floating plate 21 is slidably inserted into the guide hole 11, the conduction connector 4 is located on the side of the floating plate 21 away from the button plate 22, the two ends of the first elastic member 23 are respectively in transmission connection with the floating plate 21 and the button plate 22, and the locking block 3 is used for supporting the button plate 22.

[0040] In the above embodiment, the floating adjustment of the floating plate 21 and the conduction connector 4 can be realized through the first elastic member 23, the installation error in the crimping process can be compensated, and thereby the setting precision of the conduction connector 4 is reduced.

[0041] Further, a T-shaped bolt 221 is movably inserted into the button plate 22, and the top end of the T-shaped bolt 221 is in threaded connection with the floating plate 21. The bottom of the T-shaped bolt 221 can realize the guidance and limiting of the button plate 22, so as to avoid that the button plate 22 is bounced by the first elastic member 23 in the resetting process.

[0042] Exemplarily, the top end of the T-shaped bolt 221 is in threaded connection with the floating plate 21, and the bottom end of the T-shaped bolt 221 is in T-shaped structure, thereby realizing the guidance and limiting of the button plate 22.

[0043] Continuously referring to Figure 3 The inner wall of the base 1 has an inner flange 12, the inner flange 12 is used for limiting the conduction module 2, and the inner flange 12 and the locking block 3 are spaced apart in the first direction.

[0044] It is easy to understand that the inner flange 12 can limit the upward movement of the through connector 4, avoiding the problem that the through connector 4 moves upward too much and causes the connector of the display panel to be damaged.

[0045] Further, the second elastic member 13 is clamped between the inner flange 12 and the through module 2. During the crimping process, the second elastic member 13 is compressed. After the crimping is completed, the locking block 3 is released, and the restoring force of the second elastic member 13 causes the entire through module 2 to automatically move downward, thereby preparing for the next crimping.

[0046] In an implementation mode of the utility model, the crimping mechanism further comprises a signal transmission module 5, the signal transmission module 5 comprises a first PCB board 51, a wire 52 and a second PCB board 53, the first PCB board 51 is located on the through module 2, and the through connector 4 is located on the first PCB board 51, the wire 52 connects the first PCB board 51 and the second PCB board 53, and a plurality of test points are arranged on the second PCB board. Wherein, the second PCB board 53 can be fixed on the carrier plate.

[0047] It is easy to understand that the second PCB board 53 (regarded as a fixed end) is fixed on the carrier plate, and the first PCB board 51 (regarded as a movable end) is fixed on the movably arranged through module 2, and the two are connected in a flexible wire 52, so that the first PCB board 51 can still ensure the normal conduction of the circuit before and after moving.

[0048] Specifically, when the carrier plate is arranged on the test table, the test points of the second PCB board 53 are provided with an electrical signal by the test table, and the electrical signal passes through the wire 52, the first PCB board 51 and the through connector 4 in turn, and is finally transmitted to the connector of the display panel, thereby realizing the lighting of the screen body of the display panel.

[0049] Further, the signal transmission module 5 further comprises a power supply 54 and a plurality of lamp beads 55, the power supply 54 and the plurality of lamp beads 55 are located on the second PCB board 53, and each lamp bead 55 is electrically connected with a corresponding test point of the through connector 4, and the power supply 54 supplies power to each lamp bead 55 through the corresponding test point.

[0050] It is easy to understand that when the through connector 4 and the connector of the display panel are normally crimped and conducted, the test points of the through connector 4 are connected and conducted after being connected with the corresponding test points of the connector, forming a plurality of conducted units, at this time, the power supply 54, the lamp beads 55 and the corresponding conducted units form a closed loop, and the lamp beads 55 will be normally lit. After actual crimping, if a certain lamp bead 55 is not lit, it indicates that the test point on the through connector 4 and the corresponding test point of the connector are abnormally contacted, and should be repaired.

[0051] That is, after the crimping is completed, whether the test points on the on-off connector 4 are normally connected to the corresponding test points on the connector can be determined by observing each lamp bead 55, so that the fault can be eliminated in time.

[0052] Figure 4 is a structural schematic view of the locking block provided by the embodiment of the utility model, in combination with Figure 3 and Figure 4 As shown in the drawings, the side of the on-off module 2 can be in contact with the first inclined surface 31 to drive the locking block 3 to move, and the third elastic member 14 is clamped between the locking block 3 and the base 1 to support the locking on-off module 2 after the locking block 3 is driven to move and reset.

[0053] In the above embodiment, during the upward movement of the on-off module 2, the locking block 3 can be automatically moved in the direction away from the guide hole 11 by the on-off module 2 pressing the first inclined surface 31, so as to realize retraction (at this time, the third elastic member 14 is compressed). After the on-off module 2 is displaced above the locking block 3, the restoring force generated by the third elastic member 14 makes the locking block 3 slide out, so as to realize automatic locking of the on-off module 2.

[0054] Exemplarily, the base 1 has two guide grooves, one end of each guide groove is in vertical communication with the guide hole 11, the locking block 3 is slidably inserted into the guide groove, and the third elastic member 14 is located in the corresponding guide groove.

[0055] Exemplarily, the first elastic member 23, the second elastic member 13 and the third elastic member 14 can all be springs or rubbers.

[0056] Further, the base 1 is inserted with an unlocking button 6 which can slide in the first direction, one side of the unlocking button 6 has a second inclined surface, the locking block 3 has a third inclined surface 32, the second inclined surface is parallel to the third inclined surface 32, and the second inclined surface is used to drive the third inclined surface 32 to move in the second direction, so as to make the locking block 3 move in the direction away from the guide hole 11.

[0057] In the above embodiment, after the crimping is completed, the second inclined surface of the unlocking button 6 can press the third inclined surface 32 of the locking block 3 by driving the unlocking button 6 to move upward, and finally the locking block 3 moves transversely and retreats, so as to release the locking of the on-off module 2. That is, the on-off module 2 or the unlocking button 6 can be conveniently driven by fingers below the base 1.

[0058] Exemplarily, the base 1 is inserted with a guide shaft 16, the unlocking button 6 is provided with a strip-shaped hole, the guide shaft 16 and the strip-shaped hole are in sliding cooperation, so as to realize the guidance of the lifting of the unlocking button 6. In addition, the locking block 3 is provided with a socket 33, the top of the unlocking button 6 is inserted into the socket 33, and the third inclined surface 32 is a side inner wall of the socket 33.

[0059] In this embodiment, the base 1 has two mounting blocks 15 arranged at intervals, each mounting block 15 has a mounting hole, so that the base 1 is fixed on the carrier plate by inserting bolts in the mounting holes.

[0060] 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, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
