[0047] Example:

[0048] Figure 2 is a schematic diagram of the structure of a crimping module provided by an embodiment of the present invention, such as Figure 2 As shown, the crimping module includes a positioning component 2 and a crimping component 3.

[0049] The positioning assembly 2 includes a base 21 and a slider 22 . The base 21 is used to be arranged in the carrier 1 . The base 21 has a guide hole 211 . Figure 3 is a schematic diagram of the structure of a slider provided by an embodiment of the present invention, such as Figure 3 As shown, the slider 22 is slidably arranged on the base 21 , and has a supporting inclined surface 221 . The axial direction of the guide hole 211 is perpendicular to the supporting inclined surface 221 . The supporting inclined surface 221 is used to support the connector 200 above the connector 200 .

[0050] The base 21 includes a first base 201 and a second base 202. The first base 201 is inserted at the bottom of the carrier 1, and the second base 202 is fixed on the first base 201. The slider 22 is located on the first base 201, and the crimping assembly 3 is located on the second base 202.

[0051] Exemplarily, the second base body 202 has two spaced apart mounting blocks 204 , and each mounting block 204 has a mounting hole, so that the second base body 202 is fixed to the first base body 201 by inserting bolts into the mounting holes.

[0052] Figure 4 is a first assembly view of the crimping assembly provided by an embodiment of the present invention, Figure 5 is a second assembly view of the crimping assembly provided by an embodiment of the present invention, Figure 6 is a cross-sectional view taken along the AA line on the second seat body provided by an embodiment of the present invention, combined with Figure 4-Figure 6 As shown, the crimping assembly 3 includes a conduction module 31 and a locking block 32. The conduction module 31 is provided with a conduction connector 33 of the crimping connector 200. The conduction module 31 can be slidably inserted in the guide hole 211. The locking block 32 can be slidably inserted in the base 21, and the locking block 32 is used to be inserted into the guide hole 211 to support and lock the conduction module 31 after the conduction module 31 slides into place.

[0053] For a crimping module provided in an embodiment of the present invention, when performing a crimping test on a display panel, first, the crimping module is inserted into the carrier board 1, and the screen body 100 of the display panel is placed on the carrier board 1, and the connector 200 of the display panel passes through the through hole 11 (the through hole 11 is located on the carrier board 1), wherein the connector 200 is arranged obliquely in the through hole 11. Then, the slider 22 is driven to slide, so that the supporting inclined surface 221 moves to the top of the connector 200 and supports the connector 200. At this time, the supporting inclined surface 221 moves into the through hole 11, and accurately supports and positions the connector 200 in the through hole 11, so as to avoid the problem that the connector 200 abuts against the back of the screen body 100 and causes damage to the screen body 100 when the connector 200 is crimped upward in the subsequent process. Next, the conduction module 31 is pressed, so that the conduction connector 33 moves upward (moves obliquely upward relative to the surface of the carrier board 1, i.e., in the M direction) to conduct the connector 200 of the display panel, and the locking block 32 is moved, so that the locking block 32 supports and locks the conduction module 31. Among them, the movement of the conduction module 31 into position means that the conduction module 31 moves to the top of the locking block 32. At this time, the locking block 32 supports the bottom of the conduction module 31 (to prevent the conduction module 31 from moving downward under the action of gravity), and locks the conduction module 31 to ensure that the conduction connector 33 and the connector 200 of the display panel are always in a crimped state. After the crimping test is completed, the locking block 32 retreats to release the lock on the conduction module 31, and drives the conduction module 31 to move downward, thereby finally releasing the crimping of the conduction connector 33 on the connector 200 of the display panel. In addition, the slider 22 retreats to release the support of the slider 22 on the connector 200. At this time, the display panel can be removed to prepare for the crimping of the next display panel.

[0054] That is to say, a crimping module provided by an embodiment of the present invention can not only reliably realize crimping and connection of the inclined connector 200, but also effectively avoid the problem that the connector 200 abuts against the back of the screen body 100 when crimping the connector 200 upwards, causing damage to the screen body 100.

[0055] The crimping module only needs to be inserted into the carrier board 1, and there is no need to significantly change the structure of the carrier board itself. That is, the crimping module can be inserted into each fixture to achieve universality, thereby reducing the production cost.

[0056] Exemplarily, the conducting module 31 is provided with a positioning pin 310, and the slider 22 is provided with a positioning hole, so that the positioning pin 310 can be accurately inserted into the corresponding positioning hole during the upward movement of the conducting module 31, thereby ensuring the upward movement accuracy of the conducting module 31. In addition, the slider 22 is provided with a magnet, which can absorb the steel sheet on the connector 200, so that the connector 200 is closely attached to the supporting inclined surface 221 of the slider 22. The supporting inclined surface 221 is provided with a positioning groove, which can position the connector 200.

[0057] Exemplarily, the bottom of the carrier board 1 has a notch, the base 21 is inserted into the notch, and the notch is communicated with the through hole 11 .

[0058] Figure 7 is a schematic diagram of the assembly of the first seat body provided by an embodiment of the present invention, such as Figure 7 As shown, the positioning assembly 2 also includes a first elastic member 23, and a slide groove 212 arranged along the first direction (X-axis direction) is provided on the base 21. The slider 22 can be slidably inserted in the slide groove 212, and the first elastic member 23 is clamped between the base 21 and the slider 22.

[0059] In the above embodiment, under the action of the first elastic member 23, the slider 22 automatically moves forward to one end of the slide slot 212. At this time, the slider 22 moves precisely to the target position of one end of the slide slot 212 under the action of the first elastic member 23 (considered as the second state, the slider 22 supports the connector 200). At this position, the support slope 221 of the slider 22 just touches the connector 200 and is located above the connector 200, achieving precise support for the connector 200. After that, the crimping test can be carried out, and under the elastic force of the first elastic member 23, the slider 22 is firmly set on one end of the slide slot 212 (the slider 22 will not move back during the crimping process).

[0060] Figure 8 is a schematic diagram of the structure of a transmission assembly provided by an embodiment of the present invention, Fig. 9 is a schematic diagram of the assembly of the unlock button provided in an embodiment of the present invention, combined with Figure 8 and Fig. 9 As shown, the crimping module also includes a transmission assembly 4, which includes a movable block 41, an unlocking button 42, a limit block 43 and two connecting rods 44. The movable block 41 is slidably arranged on the base 21 along the second direction (Y-axis direction). The movable block 41 is provided with an inclined surface 411 and a guide groove 412 arranged along the first direction. One side of the unlocking button 42 has a boss 421. The unlocking button 42 is slidably arranged on the base 21 to be lifted or lowered relative to the base 21 (Z-axis direction), and the bottom of the unlocking button 42 is against the inclined surface 411 to drive the movable block 41 to slide. The limit block 43 is slidably arranged on the base 21 along the second direction to lock the boss 421 after limiting. One end of a connecting rod 44 is hinged to the base 21, and one end of the other connecting rod 44 is hinged to the slider 22. The other ends of the two connecting rods 44 are hinged and the hinge shaft is slidably matched with the guide groove 412 to drive the slider 22 to move toward the back-conducting module 31 through the two connecting rods 44.

[0061] Specifically, when the unlock button 42 is pressed down, the unlock button 42 will slide down, and the bottom of the unlock button 42 will squeeze the inclined surface 411 of the movable block 41, so that the movable block 41 slides back along the second direction. During the retreat of the movable block 41, the hinge axis of the two connecting rods 44 will be pulled correspondingly through the guide groove 412, so that the angle between the two connecting rods 44 becomes smaller, and the other connecting rod 44 will pull the slider 22 back (the slider 22 moves from one end of the slide groove 212 to the other end), so that the slider 22 retreats and disengages from the through hole 11 of the carrier 1 (regarded as the first state, the slider 22 does not support the connector 200), so as to prevent the slider 22 from interfering with the placement of the connector 200. During the retreat of the slider 22, the first elastic member 23 will be compressed. Then, the sliding limit block 43 is moved to the top of the boss 421 of the unlock button 42 for limiting. At this time, the unlocking button 42 , the movable block 41 , the connecting rod 44 and the sliding block 22 are all locked, and the first elastic member 23 will not drive the sliding block 22 to move forward and reset.

[0062] Since the sliding directions of the unlocking button 42 and the movable block 41 are different from the directions of the slider 22, and based on the transmission of the connecting rod 44, the driving of the slider 22 along the first direction can be converted into the lateral driving of the unlocking button 42 (that is, the unlocking button 42 changes the driving position and driving direction relative to the direct driving of the slider 22 through the transmission of the connecting rod 44, and only the lateral unlocking button 42 of the slider 22 is operated to complete the retracting drive of the slider 22, and the locking is achieved by operating the lateral limit block 43), which can realize the convenient recovery operation of the slider 22, avoid operating the slider 22 in the narrow space under the screen 100, and improve the testing efficiency.

[0063] It is easy to understand that when the slider is in the first state, the hinge axes of the two connecting rods 44 are at one end of the guide groove 412 ; when the slider is in the second state, the hinge axes of the two connecting rods 44 are at the other end of the guide groove 412 .

[0064] Exemplarily, the other ends of the two connecting rods 44 are hinged on a pin shaft (i.e., the hinge shaft mentioned above), a movable bearing 4121 is inserted in the guide groove 412, and one end of the pin shaft is inserted in the inner ring of the movable bearing 4121, thereby reducing friction.

[0065] In addition, in the positioning assembly 2, the slider 22 is driven forward only by the elastic force of the first elastic member 23, while the transmission assembly 4 drives the slider 22 backward and compresses the first elastic member 23. Therefore, when the slider 22 is driven to the target position, the active transmission of the transmission assembly 4 is not required, and the first elastic member 23 can be used to drive the slider 22, so that the slider 22 can be accurately moved to the end of the slide groove 212.

[0066] Fig.10 is a schematic diagram of the assembly of the first seat body and the pressure strip provided in an embodiment of the present invention, Fig.11 is a schematic diagram of the structure of the first seat body provided by an embodiment of the present invention, combined with Fig.10 and Fig.11 As shown, two spaced apart limiting grooves 215 are provided on the side walls of the base 21 corresponding to the slide groove 212 , and each limiting groove 215 extends along the first direction. Bosses are provided on two opposite sides of the slider 22 , and each boss slidably cooperates with the corresponding limiting groove 215 .

[0067] In the above embodiment, the limiting groove 215 can limit the slider 22 in the vertical direction to prevent the slider 22 from vertically disengaging from the sliding groove 212 during the sliding process.

[0068] Exemplarily, the base 21 has a step groove including steps, the inner diameter of the bottom groove is the smallest, which is regarded as the slide groove 212, and the top groove is the largest. At the same time, a pressure strip 216 is inserted, which can limit the top of the middle groove, thereby forming a limiting groove 215.

[0069] Furthermore, a plurality of guide bearings arranged at intervals are provided at the bottom of the slider 22 , and the outer ring of each guide bearing is slidably matched with the corresponding side wall of the slide groove 212 , thereby reducing the friction force on the slider 22 during the sliding process.

[0070] It should be noted that the sliding of the movable block 41 is also limited by the above-mentioned limiting grooves and guided by the guide bearings, which will not be described in detail here.

[0071] Exemplarily, the base 21 has a first positioning groove 217, the slider 22 has a second positioning groove 222, and the two ends of the first elastic member 23 are respectively inserted into the first positioning groove 217 and the second positioning groove 222, and the positioning of the two ends of the first elastic member 23 is achieved through the first positioning groove 217 and the second positioning groove 222.

[0072] Referring to the figure, the bottom of the boss 421 has a first inclined surface 4211, the top of the limit block 43 has a second inclined surface 431, the first inclined surface 4211 is parallel to the second inclined surface 431, and the first inclined surface 4211 is used to drive the second inclined surface 431 to move along the first direction.

[0073] In the above embodiment, when the unlocking button 42 moves downward, the first inclined surface 4211 presses the second inclined surface 431 , so that the limiting block 43 can automatically retreat.

[0074] Furthermore, a fourth elastic member 218 is sandwiched between the limiting block 43 and the base 21 .

[0075] It is easy to understand that when the unlocking button 42 moves downward, the limit block 43 will squeeze the fourth elastic member 218 while retreating. When the boss 421 moves to below the limit block 43, the limit block 43 can be automatically driven to extend under the action of the fourth elastic member 218, thereby realizing automatic locking of the boss 421, and the unlocking button 42 will not move up and reset.

[0076] In one implementation of the present invention, the transmission assembly 4 includes a locking button 45, which is slidably arranged on the base 21 to be raised and lowered relative to the base 21. A third inclined surface 451 is provided at the bottom of the locking button 45. The third inclined surface 451 is parallel to the second inclined surface 431. The third inclined surface 451 is used to drive the second inclined surface 431 to move along the first direction.

[0077] In the above embodiment, the locking button 45 can drive the second inclined surface 431 to move through the third inclined surface 451 during the descent process, so that the limit block 43 overcomes the elastic force of the fourth elastic member 218 and retreats, thereby also releasing the locking of the boss 421 by the limit block 43. At this time, when the first elastic member 23 drives the slider 22 to move forward, the slider 22 will be driven through the connecting rod 44, and finally the movable block 41 moves forward, and the unlocking button 42 moves up and resets, and the slider is switched to the second state.

[0078] That is, by pressing the unlock button 42, the slider 22 can be moved back to unlock the connector 200, and the display panel can be freely placed. By pressing the lock button 45, the limit of the boss 421 can be released, so that the slider 22 moves forward to position the connector 200, and the crimping can be performed on this basis.

[0079] Exemplarily, the locking button 45 is also located on one side of the screen body 100 of the display panel, and will not interfere with the screen body 100 during operation. In addition, a fifth elastic member 219 is also sandwiched between the locking button 45 and the base 21, so that it can automatically move up and reset after unlocking, avoiding interference with the movement of the limit block 43.

[0080] In this embodiment, a pressing plate 220 is provided on the base 21, and a guide hole 211 is provided on the pressing plate 220, and the unlocking button 42 can be slidably inserted in the guide hole 211. The pressing plate plays a guiding role for the unlocking button 42.

[0081] By way of example, the pressure plate can also guide the locking button 45 .

[0082] In one implementation of the present invention, the conduction module 31 includes a floating plate 311, a button plate 312 and a second elastic member 313. The floating plate 311 can be slidably inserted in the guide hole 211. The two ends of the second elastic member 313 are respectively transmission-connected to the floating plate 311 and the button plate 312. The locking block 32 is used to support and lock the button plate 312.

[0083] In the above embodiment, the second elastic member 313 can realize floating adjustment of the floating plate 311 and the conductive connector 33 , and can compensate for the installation error in the crimping and conductive process, thereby reducing the setting accuracy of the conductive connector 33 .

[0084] Furthermore, a T-bolt 3121 is movably inserted on the button plate 312, and the top of the T-bolt 3121 is threadedly engaged with the floating plate 311. The bottom of the T-bolt 3121 can guide and limit the button plate 312 to prevent the first elastic member 23 from bouncing the button plate 312 during the resetting process.

[0085] Exemplarily, the top end of the T-shaped bolt 3121 is threadedly matched with the floating plate 311 , and the bottom end of the T-shaped bolt 3121 is a T-shaped structure, thereby achieving guidance and limitation of the button plate 312 .

[0086] Continuing to refer to the figure, the inner wall of the base 21 has an inner flange 213, the inner flange 213 is used to limit the conduction module 31, and the inner flange 213 and the locking block 32 are spaced apart, and a third elastic member 214 is sandwiched between the inner flange 213 and the conduction module 31.

[0087] It is easy to understand that the inner flange 213 can limit the upward movement of the conductive connector 33, so as to avoid the problem that the conductive connector 33 moves upward too far and causes the connector 200 of the display panel to be crushed. During the crimping process, the third elastic member 214 is compressed. After the crimping is completed, after the locking block 32 releases the limit, the restoring force generated by the third elastic member 214 causes the entire conductive module 31 to automatically move downward, thereby preparing for the next crimping.

[0088] In this embodiment, the crimping module also includes a signal transmission module 5, which includes a first PCB board 51, a cable 52 and a second PCB board 53. The first PCB board 51 is located on the conduction module 31, and the conduction connector 33 is located on the first PCB board 51. The cable 52 connects the first PCB board 51 and the second PCB board 53. The second PCB board 53 is fixed on the base 21, and has multiple test points.

[0089] It is easy to understand that the second PCB board 53 (regarded as a fixed end) is fixed on the base 21, and the first PCB board 51 (regarded as a movable end) is fixed on the movable conductive module 31, and the two are connected and conductive by a flexible cable 52, so that the normal conduction of the circuit can still be guaranteed before and after the first PCB board 51 moves.

[0090] Specifically, when the carrier board 1 is arranged on the test bench, an electrical signal is provided to the second PCB board 53 through the test bench. The electrical signal passes through the flat cable 52, the first PCB board 51 and the conductive connector 33 in sequence, and is finally transmitted to the connector 200 of the display panel, thereby lighting up the screen body 100 of the display panel.

[0091] Exemplarily, a plurality of test points are provided on the back of the second PCB board 53. A plurality of avoidance holes 203 are correspondingly provided on the base 21, and the plurality of avoidance holes 203 are located in the gap. When the carrier board 1 is placed on the test bench, the test points on the test bench pass through the gap and the corresponding avoidance holes to be connected with the plurality of test points on the second PCB board 53, thereby finally lighting up the display panel. In addition, the button board 312 and the driving button 6 described later can also be operated from the bottom of the carrier board 1 through the corresponding avoidance holes.

[0092] Furthermore, the signal transmission module 5 also includes a power supply 54 and multiple lamp beads 55, which are all located on the second PCB board 53, and each lamp bead 55 is electrically connected to a test point corresponding to the conductive connector 33, and the power supply 54 supplies power to each lamp bead 55 through the corresponding test point.

[0093] It is easy to understand that when the conductive connector 33 and the connector 200 of the display panel are crimped and normally connected, each test point on the conductive connector 33 is connected by the corresponding test point of the connector 200 and then turned on, forming a plurality of conductive units that have been turned on. At this time, the power supply 54, each lamp bead 55 and each corresponding conductive unit form a closed loop, and each lamp bead 55 will be lit normally. After the actual crimping, if a lamp bead 55 does not light up, it means that the contact between the test point on the conductive connector 33 and the test point corresponding to the connector 200 is abnormal, and it should be repaired.

[0094] That is to say, after the crimping is completed, by observing each lamp bead 55, it can be determined whether each test point on the conductive connector 33 is normally connected and conductive with the corresponding test point of the connector 200, so that the fault can be eliminated in time.

[0095] Exemplarily, a glass 12 is inserted on the carrier 1, and the glass 12 faces the plurality of lamp beads 55, so that it is convenient to observe whether each lamp bead 55 is normally lit through the transparent property of the glass 12 above the carrier 1. A positioning tongue module 13 is also provided on the carrier 1.

[0096] Fig.12 is a schematic diagram of the structure of the locking block provided in an embodiment of the present invention, combined with Figure 6 and Fig.12 As shown, a first inclined surface 321 is provided on the side of the locking block 32 facing the guide hole 211, and the side edge of the conductive module 31 can contact the first inclined surface 321 to drive the locking block 32 to move, and a sixth elastic member 230 is clamped between the locking block 32 and the base 21 to support and lock the conductive module 31 after driving the locking block 32 to move and reset.

[0097] In the above embodiment, when the conduction module 31 moves upward, the conduction module 31 squeezes the first inclined surface 321 to automatically move the locking block 32 in the direction away from the guide hole 211, thereby achieving retraction (the sixth elastic member 230 is compressed at this time). After the conduction module 31 moves to the top of the locking block 32, the restoring force generated by the sixth elastic member causes the locking block 32 to slide out, thereby achieving automatic locking of the conduction module 31.

[0098] Exemplarily, the base 21 has two guide grooves, one end of each guide groove is vertically connected to the guide hole 211 , the locking block 32 can be slidably inserted in the guide groove, and the sixth elastic member 230 is located in the corresponding guide groove 412 .

[0099] Exemplarily, each elastic member may be a spring or rubber.

[0100] Further, a slidable driving button 6 is inserted in the base 21, and a second inclined surface is provided on one side of the driving button 6, and a third inclined surface 322 is provided on the locking block 32. Preferably, the second inclined surface is parallel to the third inclined surface 322. The second inclined surface is used to drive the third inclined surface 322 to move along the second direction, so that the locking block 32 moves in a direction away from the guide hole 211.

[0101] In the above embodiment, after the crimping is completed, the driving button 6 is driven to move upward, so that its second inclined surface can press the third inclined surface 322 of the locking block 32, and finally the locking block 32 retreats, thereby releasing the lock of the conduction module 31. That is, the conduction module 31 or the driving button 6 can be conveniently driven by fingers under the base 21.

[0102] Exemplarily, a guide shaft is inserted on the base 21, and a bar hole is provided on the driving button 6. The guide shaft and the bar hole are slidably matched, thereby guiding the lifting and lowering of the driving button 6. In addition, a plug hole 323 is provided on the locking block 32, and the top of the driving button 6 is inserted into the plug hole 323. The third inclined surface 322 is an inner wall of one side of the plug hole 323.

[0104] Fig.15 is a flow chart of a crimping method provided by an embodiment of the present invention, such as Fig.15 As shown, the crimping method is based on the above-mentioned crimping carrier, and the crimping method includes:

[0105] S1 . Place the screen body 100 of the display panel on the carrier board 1 , and pass the connector 200 of the display panel through the through hole 11 .

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
