[0023] Regarding a crimping device provided by an embodiment of the present invention, when crimping a display panel (the connector of the display panel is located on the back of the screen body and arranged at an angle), first, the screen body of the display panel is placed on the test bench, at which time the connector will pass through the first through hole, and the cable of the connector will be tilted and placed on the first support surface, while the conductive part of the connector is located in the second through hole. Then, the slider is slid by the driving member so that the second supporting surface on the slider moves above the first supporting surface, and at this time, the cable of the connector is clamped between the second supporting surface and the first supporting surface, and the second supporting surface is simultaneously located above the conductive part of the connector (that is, the supporting area of ​​the second supporting surface is larger than the supporting area of ​​the first supporting surface) and is in contact with the conductive part, thereby finally completing the precise fixation of the connector and avoiding the problem that the position of the connector cannot be fixed after the display panel is loaded.

[0024] Next, the crimping assembly presses upward against the conductive portion of the connector, ultimately lighting the screen. Because the second support surface is located above the connector and abuts against the conductive portion, it supports the conductive portion during upward crimping. The connector remains tilted relative to the screen and is not pushed upward, preventing damage to the screen caused by the connector abutting against the back of the screen.

[0025] That is to say, the crimping device provided by the embodiment of the present invention can not only achieve precise fixation of the inclined connector on the back of the screen, but also always keep the connector tilted relative to the screen, thereby ensuring the accuracy of subsequent crimping and effectively avoiding the problem of damage to the screen.

[0044] Example:

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

[0046] Figure 1 Schematic diagram of the structure of the display panel provided by the embodiment of the present invention. Figure 1 As shown, the display panel 10 includes a screen body 100 and a connector 200. 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 cable 201 and a conductive portion 202 (having multiple test points). The two ends of the cable 201 are respectively connected to the screen body 100 and the conductive portion 202.

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

[0048] Figure 3 Schematic diagram of the structure of the test bench provided by the embodiment of the present invention. Figure 3 As shown, the test platform 1 has a first through hole 11 .

[0049] Figure 4 This is a first view of a connector positioning assembly provided by an embodiment of the present invention. Figure 5 This 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 Schematic diagram of the structure of the slider provided by the embodiment of the present invention. 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 at an angle. 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 conductive portion 202 of the conductive 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 this time, the connector 200 will pass through the first through hole 11, and the cable 201 of the connector 200 will be tilted and placed on the first support surface 211, while the conductive part 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 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 in contact with 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 conductive portion 202 of the conductive connector 200 is pressed upward by the crimping assembly, ultimately lighting up the screen 100. Because the second support surface 221 is located above the connector 200 and in contact with the conductive portion 202, the second support surface 221 supports the conductive portion 202 of the connector 200 during the upward crimping operation. The connector 200 remains tilted relative to the screen 100 and is not pushed upward, preventing the connector 200 from abutting 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 precise fixation of the inclined 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 the problem of damage to the screen body 100.

[0055] For example, the test bench 1 includes a support plate and a box body, wherein the support plate cover is provided on the box body to seal the box body, the positioning block 21 is provided 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 support surface 211, and the crimping member is used to pass through the second through hole 212 and then crimp the conductive part 202 of the conductive connector 200, thereby realizing 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 configured to be manual, that is, the conductive portion 202 of the conductive connector 200 is crimped by flipping the probe module.

[0059] In addition, the present 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 one 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 structural diagram of a driving member provided by an embodiment of the present invention, Figure 8 This 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. A first elastic member 14 is provided 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, and 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, causing the inclined wedge block 231 to slide along the second direction.

[0063] As the inclined wedge 231 slides, it drives the movable bearing 235 to slide in the first direction, and the angle between the two connecting rods 234 gradually increases, thereby driving the slider 22 to slide in the first direction, so that the second supporting surface 221 of the slider 22 moves toward the connector 200 (see FIG. Figure 9), thereby finally completing the clamping and fixing of the connector 200 through the 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 directions 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 drive of the locking button 232 in the lateral direction (that is, the locking button 232 changes the drive position and drive direction relative to the direct drive of the slider 22 through the transmission of the connecting rod 234, avoiding the method of operating 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). This not only reduces the overall size of the entire driving member 23 (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 easily operated, thereby improving the testing 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 a hinge seat 225 , which is hinged to the connecting rod 234 via the corresponding hinge 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 the boss 2321. At this time, under the force of the first elastic member 14, the slider 22 automatically retreats in the first direction, eliminating the need to drive the slider 22 backward. The angle between the two connecting rods 234 decreases, and the movable bearing 235, the inclined wedge 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, since the slider 22 is no longer clamped on the connector, the display panel can be freely removed and placed.

[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, thereby realizing the automatic locking of the boss 2321 by the hook 233 after driving the slider 22 to move into position, that is, finally realizing the locking of the slider 22, avoiding the problem of manual operation of the hook 233 to achieve locking, and improving the testing efficiency.

[0068] Exemplarily, the driving portion 2332 is located below the hook portion 2331. The connection between the hook portion 2331 and the driving portion 2332 is achieved by a rotating shaft so as to be rotatably mounted on the positioning block 21.

[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 locked, the unlock button 236 is driven downward, which in turn drives the hook 233 to rotate, causing the hook 233 to release its hooking from the boss 2321. Thereafter, driven by the first elastic member 14, the slider 22 and the wedge 231 retreat, while the lock button 232 moves upward, causing the boss 2321 to be higher than the hooking portion 2331, ultimately achieving unlocking. This releases the connector 200 from its clamping position, allowing the display panel 10 to be freely removed.

[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] For example, 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 achieve a double insurance effect.

[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] Figure 10 FIG. 1 is a schematic diagram of an assembly of a fixing block provided in an embodiment of the present invention. Figure 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 is located above the slider 22. The locking button 232 and the unlocking button 236 slide in conjunction 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 apart 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 into the groove 12. The groove 12 can achieve 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 100 onto the test bench 1 .

[0082] It is easy to understand that when the two tongue modules 13 move toward each other and approach each other, the two tongue modules 13 can press the two ends of the screen 100, so that the screen 100 is reliably pressed on the test bench 1, and the screen 100 is prevented from moving on the test bench 1 during the pressing process. When the screen 100 needs to be replaced, the two tongue modules 13 are slid away from each other to release the pressure on the screen 100.

[0083] Exemplarily, a positioning groove 16 is provided on the top surface of the test bench 1 . The positioning groove 16 is communicated with the first through hole 11 . The positioning groove 16 is used to position the screen body 100 .
