[0044] Example:

[0045] In order to better understand the structure of the carrier, the structure of the display panel 10 is briefly introduced:

[0046] Figure 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present invention, such as Figure 1 As shown, the display panel 10 includes a screen body 100 and a connector 200, wherein the connector 200 is located on the back of the screen body 100 and is arranged obliquely relative to the screen body 100. The connector 200 includes a flat cable 201 and a conductive portion 202 (having multiple test points), and two ends of the flat cable 201 are connected to the screen body 100 and the conductive portion 202 respectively.

[0047] Figure 2 is a schematic diagram of the structure of a crimping device provided by an embodiment of the present invention, such as Figure 2 As shown, the crimping device includes a test bench 1, a connector positioning assembly 2 and a crimping assembly.

[0048] Figure 3 is a schematic diagram of the structure of the test bench provided by an embodiment of the present invention, such as Figure 3 As shown, the test bench 1 has a first through hole 11 .

[0049] Figure 4 is a first view of a connector positioning assembly provided by an embodiment of the present invention, Figure 5 is a second view of the connector positioning assembly provided by an embodiment of the present invention, combined with Figure 4 and Figure 5As shown, the connector positioning assembly 2 includes a positioning block 21, a slider 22 and a driving member 23. The positioning block 21 is arranged in the test bench 1. The positioning block 21 has a first supporting surface 211 and a second through hole 212. The first supporting surface 211 is used to support the cable 201 of the connector 200, and one side of the first supporting surface 211 extends into the second through hole 212. The second through hole 212 is connected to the first through hole 11.

[0050] Figure 6 is a schematic diagram of the structure of a slider provided by an embodiment of the present invention, such as Figure 6 As shown, the slider 22 has a second supporting surface 221, and the second supporting surface 221 is used to support the conductive portion 202 and the cable 201 of the connector 200. The first supporting surface 211 and the second supporting surface 221 are both arranged obliquely, and the slider 22 is slidably arranged on the positioning block 21 along the first direction (X-axis direction). The output end of the driving member 23 is transmission-connected to the slider 22 to drive the second supporting surface 221 to move toward the direction of the first supporting surface 211 to clamp the cable 201 of the connector 200.

[0051] The crimping assembly is located on the test bench 1 , and is used to crimp the conducting portion 202 of the conducting connector 200 .

[0052] For a crimping device provided in an embodiment of the present invention, when crimping a display panel 10 (the connector 200 of the display panel 10 is located on the back of the screen body 100 and is arranged at an angle), first, the screen body 100 of the display panel 10 is placed on the test bench 1, at which time the connector 200 passes through the first through hole 11, and the cable 201 of the connector 200 is tilted and placed on the first support surface 211, while the conductive portion 202 of the connector 200 is located in the second through hole 212. Then, the slider 22 is slid by the driving member 23, so that the second supporting surface 221 on the slider 22 moves to above the first supporting surface 211, and at this time, the second supporting surface 221 and the first supporting surface 211 clamp the cable 201 of the connector 200, and the second supporting surface 221 is also located above the conductive part 202 of the connector 200 (that is, the supporting area of ​​the second supporting surface 221 is larger than the supporting area of ​​the first supporting surface 211), and is attached to the conductive part 202, thereby finally completing the precise fixation of the connector 200, avoiding the problem that the position of the connector 200 cannot be fixed after the display panel 10 is loaded.

[0053] Next, the conducting part 202 of the conducting connector 200 is crimped upward by the crimping assembly, thereby finally lighting up the screen 100. Since the second supporting surface 221 is located above the connector 200 and is in contact with the conducting part 202, the second supporting surface 221 can support the conducting part 202 of the connector 200 during upward crimping, and the connector 200 always remains tilted relative to the screen 100 and will not be pushed upward, thereby avoiding the problem of the connector 200 abutting against the back of the screen 100 and causing damage to the screen 100.

[0054] That is to say, the crimping device provided by the embodiment of the present invention can not only achieve the precise fixation of the tilted connector 200 on the back of the screen body 100, but also always keep the connector 200 tilted relative to the screen body 100, thereby ensuring the accuracy of subsequent crimping and effectively avoiding damage to the screen body 100.

[0055] Exemplarily, the test bench 1 comprises a support plate and a box body, wherein the support plate cover is arranged on the box body to seal the box body, the positioning block 21 is arranged on the back of the support plate, and the crimping assembly is located in the box body.

[0056] It is easy to understand that after the crimping test is completed, the slider 22 is driven to retreat, that is, the first support surface 211 moves and is misaligned with the second support surface 221, thereby releasing the clamping of the connector 200. At this time, the display panel 10 can be removed from the crimping device, and the next display panel 10 can be tested.

[0057] Exemplarily, the crimping assembly includes a lifting member and a probe module (not shown), the lifting member is located below the positioning block 21, the lifting member is used to drive the probe module to lift and lower (Z-axis direction), and the lifting direction of the crimping member is perpendicular to the first supporting surface 211, the crimping member is used to pass through the second through hole 212 and then crimp the conductive portion 202 of the conductive connector 200, thereby achieving automatic crimping through the crimping assembly.

[0058] It should be noted that in other embodiments of the present invention, the crimping assembly can also be set to a manual mode, that is, the conductive part 202 of the conductive connector 200 is crimped by flipping the probe module.

[0059] In addition, the crimping device only needs to set a positioning block 21 on the test bench 1 and adjust the crimping direction of the crimping assembly, without significantly changing the structure of the crimping device itself.

[0060] In an implementation of the present invention, the driving member 23 may be a driving structure such as a cylinder, a linear motor or a screw, and the present invention does not limit this.

[0061] In another implementation of the present invention, Figure 7 is a schematic structural diagram of a driving member provided by an embodiment of the present invention, Figure 8 is a schematic diagram of a first state of a driving member provided by an embodiment of the present invention, combined with Figure 7 and Figure 8 As shown, the driving member 23 includes an inclined wedge block 231, a locking button 232, a hook 233, two connecting rods 234 and a movable bearing 235. The inclined wedge block 231 is slidably arranged on the positioning block 21 along the second direction (Y-axis direction). One side of the locking button 232 has a boss 2321. The locking button 232 is slidably arranged on the positioning block 21 to rise and fall relative to the positioning block 21, and the bottom of the locking button 232 abuts against the inclined surface of one side of the inclined wedge block 231 to drive the inclined wedge block 231. Sliding, the hook 233 is rotatably arranged on the positioning block 21 to hook the rear locking boss 2321, one end of a connecting rod 234 is hinged to the positioning block 21, and one end of the other connecting rod 234 is hinged to the slider 22, and the other ends of the two connecting rods 234 are hinged to the inner ring of the movable bearing 235, and the other side of the inclined wedge block 231 is slidably matched with the outer ring of the movable bearing 235 along the first direction, and a first elastic member 14 is arranged between the slider 22 and the positioning block 21 to reset the sliding slider.

[0062] Specifically, when the connector 200 on the crimping device needs to be clamped and fixed, the locking button 232 is pressed down, the locking button 232 will slide down, and the bottom of the locking button 232 will squeeze the inclined surface of the inclined wedge block 231, so that the inclined wedge block 231 slides along the second direction.

[0063] During the sliding process of the inclined wedge block 231, the movable bearing 235 is driven to slide along the first direction, and the angle between the two connecting rods 234 is gradually increased, thereby driving the slider 22 to slide along the first direction, so that the second supporting surface 221 of the slider 22 moves toward the direction of the connector 200 (see FIG. Fig. 9), so that the connector 200 is finally clamped and fixed through two supporting surfaces, which is convenient for subsequent crimping and testing. In addition, since the sliding directions of the locking button 232 and the inclined wedge block 231 are different from the direction of the slider 22, and based on the transmission of the connecting rod 234, the drive of the slider 22 along the first direction can be converted into the lateral drive of the locking button 232 (that is, the locking button 232 changes the driving position and driving direction relative to the direct drive of the slider 22 through the transmission of the connecting rod 234, avoiding the operation of the slider 22 under the screen body 100, and only operating the locking button 232 on the side of the slider 22 can complete the drive of the slider 22), not only can the overall size of the entire driving member 23 be reduced (the length and width reach 70-80mm), the structure is compact, the space occupied is small, the cost is low, and the slider 22 can be conveniently operated, thereby improving the test efficiency. At the same time, the hook 233 is driven to rotate so that the hook 233 hooks and locks the boss 2321, thereby completing the locking of the locking button 232 and the inclined wedge block 231, and finally completing the locking of the connecting rod 234 and the slider 22, so that the slider 22 can continue to be clamped on the connector 200.

[0064] Exemplarily, both the slider 22 and the positioning block 21 have an articulated seat 225 , and the articulated seat 225 is hinged to the connecting rod 234 via the corresponding articulated seat 225 .

[0065] It is easy to understand that after the display panel crimping test is completed, the hook 233 is rotated in the opposite direction to release the hook 233 from locking the boss 2321. At this time, under the action of the first elastic member 14, the slider 22 automatically retreats along the first direction, and there is no need to drive the slider 22 back, and the angle between the two connecting rods 234 is reduced, and the movable bearing 235, the inclined wedge block 231 and the locking button 232 all automatically retreat, thereby preparing for the clamping and fixing of the connector of the next display panel. In addition, at this time, since the slider 22 has released the clamping and fixing of the connector, the display panel can be freely taken in and out.

[0066] Furthermore, the hook 233 includes a hooking portion 2331 and a driving portion 2332 connected to each other, the boss 2321 can drive the hooking portion 2331 to rotate, and a second elastic member 15 is provided between the driving portion 2332 and the positioning block 21 so that the hooking portion 2331 can re-hook the boss 2321 after the hook 233 rotates.

[0067] In the above embodiment, the boss 2321 can drive the hook 233 to open automatically during the downward movement, and after continuing to move downward, the second elastic member 15 can make the hook 233 rotate and hook the boss 2321, so that after driving the slider 22 to move into place, the hook 233 can automatically lock the boss 2321, that is, finally lock the slider 22, avoid the problem of manual operation of the hook 233 to achieve locking, and improve the test efficiency.

[0068] Exemplarily, the driving portion 2332 is located below the hooking portion 2331. The connection between the hooking portion 2331 and the driving portion 2332 is rotatably mounted on the positioning block 21 via a rotating shaft.

[0069] In addition, the driving member 23 also includes an unlocking button 236, which is slidably arranged on the positioning block 21 to rise and fall relative to the positioning block 21. The bottom of the unlocking button 236 abuts against the hook 233 to drive the hook portion 2331 to rotate back to the boss 2321 and then unlock.

[0070] In the above embodiment, when the slider 22 is in the locked state, the unlock button 236 is driven to move downward, and the unlock button 236 drives the hook 233 to rotate, so that the hook 233 releases the hook connection with the boss 2321. Thereafter, driven by the first elastic member 14, the slider 22 and the inclined wedge block 231 will retreat, and the lock button 232 will move upward, so that the boss 2321 is higher than the hooking portion 2331, and finally unlocking is achieved, thereby releasing the clamping fixation of the connector 200, and finally the display panel 10 can be freely taken in and out.

[0071] In addition, after unlocking is completed, when the downward pressure on the unlock button 236 is removed, the hook 233 will automatically rotate under the elastic force of the second elastic member 15, and the hook portion 2331 will drive the unlock button 236 to move upward, so that the unlock button 236 moves upward and resets.

[0072] Exemplarily, a third elastic member 17 is provided between the unlocking button 236 and the positioning block 21 to drive the unlocking button 236 to move upward. The third elastic member 17 can cooperate with the second elastic member 15 to realize the function of double insurance.

[0073] Exemplarily, the first elastic member 14 , the second elastic member 15 and the third elastic member 17 may be springs.

[0074] That is, the driving member 23 provided by the present invention can automatically slide and lock the slider 22 by pressing the locking button 232 , and can automatically unlock the slider 22 by pressing the unlocking button 236 .

[0075] In this embodiment, the positioning block 21 includes a base 213 and a shell 214. The shell 214 is detachably fixed to the outer edge of the base 213 and forms a protective space. The second through hole 212 passes through the shell 214, the protective space and the base 213. The slider 22 slides with the base 213 and is located in the protective space. The first support surface 211 is located on the shell 214.

[0076] In the above embodiment, the housing 214 can provide a cover and protection for the slider 22 .

[0077] Exemplarily, the oblique wedge block 231 and the hook 233 are both located on the base 213, and the oblique wedge block 231 and the connecting rod 234 are located in the protection space.

[0078] Fig.10 is a schematic diagram of the assembly of the fixing block provided in an embodiment of the present invention, such as Fig.10 As shown, the base 213 has a fixed block 18, and a guide seat 19 is installed on the fixed block 18. The guide seat 19 is spaced apart from the base 213, and the guide seat 19 is located above the slider 22. The locking button 232 and the unlocking button 236 slide in cooperation with the corresponding guide holes on the guide seat 19.

[0079] Exemplarily, the guide seat 19 is inserted into the shell 214, and the locking button 232 and the unlocking button 236 extend out of the shell 214 and the test bench 1, and are spaced from the screen body 100, so that the locking and unlocking of the slider 22 can be conveniently completed at the edge of the test bench 1.

[0080] Furthermore, the test bench 1 has a groove 12, one side of the groove 12 extends to the side of the test bench 1, and the housing 214 is detachably inserted in the groove 12. The groove 12 can realize accurate positioning of the housing 214.

[0081] Exemplarily, at least two tongue modules 13 are arranged at intervals on the top surface of the test bench 1 , and each tongue module 13 is slidably arranged on the test bench 1 to press the screen body 100 onto the test bench 1 .

[0085] In the above embodiment, the positioning space formed by the U-shaped positioning block 222 can realize the precise positioning of the conductive part 202 of the connector 200, further ensuring the subsequent crimping accuracy. In addition, the conductive part 202 of the connector 200 can be magnetically attracted by the magnet 223, so that the conductive part 202 is closely attached to the second supporting surface 221, ensuring the layout accuracy of the conductive part 202 and preventing the conductive part 202 from tilting downward.

[0086] Exemplarily, the number of magnets 223 is two.

[0087] It should be noted that the conductive portion 202 of the connector 200 has a steel sheet, so that the magnet 223 can achieve magnetic attraction to the conductive portion 202 .

[0088] Exemplarily, a plurality of spaced-apart bushings 224 are inserted into the slider 22, and a plurality of spaced-apart guide rods 215 are provided on the positioning block 21. Each guide rod 215 can be slidably inserted into a corresponding bushing 224. The bushing 224 can guide the guide rod 215, thereby ensuring the sliding accuracy of the slider 22 and thus ensuring the positioning accuracy of the connector 200.
