If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0034] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0035] See Figure 1 and Figure 2As shown, the present application provides a crimping mechanism 100, which includes a machine table 110 and at least two crimping modules 120. The machine table 110 has a loading table (not shown in the figure), which is used to carry the product to be tested 200, such as a loading cavity, and the product to be tested 200 is placed in the loading cavity to stably carry the product to be tested 200. The crimping mechanism 100 is used to test the electrical crimping of the product to be tested 200 to test whether the product to be tested 200 is qualified or not. Wherein, the product to be tested 200 can be a display module, a chip, a battery unit, etc., and the specific element type of the product to be tested 200 is not limited by the present application.

[0036] The plurality of crimping modules 120 are rotationally arranged on the machine table 110, and any crimping module 120 can be rotated to a position opposite to the product to be tested 200, such as in the embodiment, any crimping module 120 can be rotated to a position close to the top of the product to be tested 200, so that the crimping part of the crimping module 120 corresponds to the test part of the product to be tested 200. The plurality of crimping modules 120 are movably arranged on the machine table 110, and the plurality of crimping modules 120 can move towards the direction close to or away from the product to be tested 200. For example, any crimping module 120 is rotated to a position opposite to the product to be tested 200, and the crimping module 120 moves towards the direction close to the product to be tested 200 to realize the electrical crimping test of the crimping module 120 on the product to be tested 200. After the test of the product to be tested 200 is completed, the crimping module 120 moves towards the direction away from the product to be tested 200, and the crimping module 120 is separated from the product to be tested 200, which facilitates the replacement of different crimping modules 120 for the crimping test of the product to be tested 200 and the replacement of the product to be tested 200.

[0037] The above-mentioned crimping mechanism 100, since the plurality of crimping modules 120 are rotationally arranged on the machine table 110, and any crimping module 120 can be rotated to a position opposite to the product to be tested 200, different crimping modules 120 can be switched for the crimping test of the product to be tested 200, and the crimping modules 120 with different test functions can meet the diversified test requirements of the product to be tested 200, and only the crimping mechanism 100 can be used for different function tests of the product to be tested 200, which simplifies the test action and reduces the test cost.

[0038] In an embodiment, referring to Figure 1 and Figure 2As shown, there are two crimping modules 120, both of which are rotatably mounted on the machine base 110 and are spaced apart along the Z-direction. For example, if the two crimping modules 120 are defined as a first crimping module 130 and a second crimping module 140, both are rotatably mounted on the machine base 110 and are spaced apart along the Z-direction. First, the first crimping module 130 rotates to the side closer to the product under test 200, and the first crimping module 130 is opposite to the product under test 200, while the second crimping module 140 rotates to the side away from the product under test 200. Next, both the first crimping module 130 and the second crimping module 140 move towards the product under test 200, and the first crimping module 130 crimps onto the product under test 200, performing an electrical crimping test on the product under test 200. Continuing, after the first crimping module 130 completes its test on the product under test 200, both the first crimping module 130 and the second crimping module 140 move away from the product under test 200, and the first crimping module 130 separates from the product under test 200. Then, the first crimping module 130 and the second crimping module 140 move relative to the machine platform 110 along... Figure 1 The second crimping module 140 rotates 180° in the θ direction, moving closer to the product under test 200 and facing it. The first crimping module 130 rotates away from the product under test 200. Then, both the first crimping module 130 and the second crimping module 140 move towards the product under test 200, and the second crimping module 140 crimps onto the product under test 200, performing an electrical crimping test. Finally, after the second crimping module 140 completes its test on the product under test 200, both the first crimping module 130 and the second crimping module 140 move away from the product under test 200, separating from it. Through the above operations, by rotating and moving the first crimping module 130 and the second crimping module 140, two crimping tests on the product under test 200 can be completed.

[0039] The aforementioned crimping mechanism 100 can switch between two crimping modules 120 to perform crimping tests on the product under test 200. The two crimping modules 120 can meet the diverse testing needs of the product under test 200. Different functional tests of the product under test 200 can be performed using only the crimping mechanism 100, simplifying the testing process and reducing testing costs.

[0040] It should be noted that the specific number of the crimping modules 120 is not limited to two as provided in the above embodiment, and the number of the crimping modules 120 can also be three, four or other numbers. The specific number of the crimping modules 120 is not limited in the present application. When the number of the crimping modules 120 is other numbers, the plurality of crimping modules 120 are arranged at intervals along the circumferential direction of the machine table 110. The crimping action of the plurality of crimping modules 120 on the product to be tested 200 can be performed according to the above embodiment, and will not be described here. Moreover, when the number of the crimping modules 120 is other numbers, and at least two crimping modules 120 have different test functions, the crimping mechanism 100 can meet the different functional test requirements of the product to be tested 200. When the number of the crimping modules 120 is other numbers, and the plurality of crimping modules 120 have the same test function, the crimping mechanism 100 can perform multiple electrical crimping tests on the product to be tested 200 to improve the test reliability of the product to be tested 200.

[0041] In an embodiment, referring to FIG. 1, Figure 1 As shown in FIG. 1, the crimping mechanism 100 further comprises a rotating module 150 and a Z-direction driving module 160. The rotating module 150 and the Z-direction driving module 160 are both arranged on the machine table 110. For example, the Z-direction driving module 160 is arranged on the machine table 110 by welding, screwing or other methods. The rotating module 150 is arranged on the Z-direction driving module 160 by welding, screwing or other methods. The rotating module 150 is indirectly arranged on the machine table 110 through the Z-direction driving module 160. The rotating module 150 is in transmission connection with the plurality of crimping modules 120. For example, the plurality of crimping modules 120 are fixed to the rotating module 150 by mounting brackets 151. The mounting brackets 151 can associate the rotating and moving actions of the plurality of crimping modules 120 with each other. The rotating module 150 is used to drive the plurality of crimping modules 120 to rotate synchronously relative to the machine table 110, so as to rotate any crimping module 120 to a position opposite to the product to be tested 200, and select any crimping module 120 to perform electrical crimping test on the product to be tested 200. The Z-direction driving module 160 is used to drive the plurality of crimping modules 120 to move towards or away from the product to be tested 200. For example, the Z-direction driving module 160 can drive the plurality of crimping modules 120 to move in the vertical direction as shown in FIG. 1, so as to drive the plurality of crimping modules 120 to crimp the product to be tested 200, or drive the plurality of crimping modules 120 to separate from the product to be tested 200. Figure 1 As shown in FIG. 1, the Z-direction driving module 160 is arranged on the machine table 110 by welding, screwing or other methods. The rotating module 150 is arranged on the Z-direction driving module 160 by welding, screwing or other methods. The rotating module 150 is indirectly arranged on the machine table 110 through the Z-direction driving module 160. The rotating module 150 is in transmission connection with the plurality of crimping modules 120. For example, the plurality of crimping modules 120 are fixed to the rotating module 150 by mounting brackets 151. The mounting brackets 151 can associate the rotating and moving actions of the plurality of crimping modules 120 with each other. The rotating module 150 is used to drive the plurality of crimping modules 120 to rotate synchronously relative to the machine table 110, so as to rotate any crimping module 120 to a position opposite to the product to be tested 200, and select any crimping module 120 to perform electrical crimping test on the product to be tested 200. The Z-direction driving module 160 is used to drive the plurality of crimping modules 120 to move towards or away from the product to be tested 200. For example, the Z-direction driving module 160 can drive the plurality of crimping modules 120 to move in the vertical direction as shown in FIG. 1, so as to drive the plurality of crimping modules 120 to crimp the product to be tested 200, or drive the plurality of crimping modules 120 to separate from the product to be tested 200.

[0042] In the present embodiment, the rotating module 150 is a rotating motor, and the Z-direction driving module 160 is a Z-direction driving electric cylinder. Of course, in other possible embodiments, the rotating module 150 can also be a rotating electric cylinder, a rotating hydraulic cylinder or other elements capable of outputting power. The Z-direction driving module 160 can also be a Z-direction driving motor, a Z-direction driving hydraulic cylinder or other elements capable of outputting power. The specific types of the rotating module 150 and the Z-direction driving module 160 are not limited in the present application.

[0043] In one embodiment, referring to Figure 1 and Figure 2 As shown, the compression module 120 includes a body 121 and a plurality of test pieces 122, the plurality of test pieces 122 are arranged in an array on the body 121, and the plurality of test pieces 122 are arranged at intervals. The body 121 is arranged on the machine table 110, and exemplarily, the body 121 is enclosed by a top plate 1211, a side plate 1212 and a bottom plate 1213, and at least one of the top plate 1211, the side plate 1212 and the bottom plate 1213 can be connected to the mounting bracket 151 by screwing, welding or the like, so as to realize the connection and fixation between the body 121 and the machine table 110. When the compression module 120 moves towards the direction close to the product to be tested 200, the test piece 122 can be compressed on the product to be tested 200, and the test piece 122 and the product to be tested 200 are electrically connected, so as to realize the electrical compression test of the product to be tested 200 by the compression module 120.

[0044] It should be noted that the number of test pieces 122 can be set according to the test points of the product to be tested 200, such as the number of test pieces 122 and the number of test points of the product to be tested 200 are consistent, so that when the compression module 120 compresses the product to be tested 200, the plurality of test pieces 122 can complete the compression test of the product to be tested 200 at one time, and the test efficiency of the product to be tested 200 is improved.

[0045] Specifically, referring to Figures 1-3 As shown, the test piece 122 includes a connecting shaft 1221 and a compression head 1222, the connecting shaft 1221 is movably inserted into the body 121 along the axial direction of the connecting shaft 1221, and the compression head 1222 is connected to the end of the connecting shaft 1221, such as the compression head 1222 is connected to the connecting shaft 1221 by means of a high screw 1223, and the high screw 1223 limits the free movement of the compression head 1222 on the basis of locking the compression head 1222. The compression head 1222 can be compressed on the product to be tested 200 to perform electrical compression test on the product to be tested 200, and since the connecting shaft 1221 can move relative to the body 121, the compression head 1222 and the product to be tested 200 are flexibly and floatingly compressed, so as to avoid damaging the product to be tested 200 during the compression process of the compression head 1222. Preferably, the compression head 1222 is a copper structure, which can not only ensure good electrical conductivity between the compression head 1222 and the product to be tested 200 to form stable electrical conduction during the compression of the compression head 1222 on the product to be tested 200, but also ensure sufficient structural strength of the compression head 1222 and reduce the manufacturing cost of the compression head 1222.

[0046] Further, referring to Figures 1-3As shown, the body 121 is provided with a plurality of guide holes 1214, such as the guide hole 1214 formed in the bottom plate 1213, and the plurality of guide holes 1214 are arranged at intervals. Preferably, the guide hole 1214 is integrally formed on the bottom plate 1213 by injection molding, extrusion or the like, so as to simplify the forming process of the guide hole 1214. The cross section of the connecting shaft 1221 in the plane perpendicular to the axis direction thereof is shaped, and since the connecting shaft 1221 is inserted into the guide hole 1214, the guide hole 1214 is also shaped. For example, the cross section of the connecting shaft 1221 in the plane perpendicular to the axis direction thereof is D-shaped or crescent-shaped, that is, the connecting shaft 1221 is edge-cut processed so that the connecting shaft 1221 is a D-shaped shaft or a crescent-shaped shaft as a whole, and the shape of the guide hole 1214 is adapted to the shape of the connecting shaft 1221. For example, when the connecting shaft 1221 is a D-shaped shaft, the guide hole 1214 is a D-shaped hole, and for example, when the connecting shaft 1221 is a crescent-shaped shaft, the guide hole 1214 is a crescent-shaped hole.

[0047] The test device described above sets the connecting shaft 1221 as a shaped shaft, such as a D-shaped shaft or a crescent-shaped shaft, so that the connecting shaft 1221 cannot rotate during the movement of the connecting shaft 1221 relative to the body 121 along the axis direction thereof, thereby ensuring the stability and reliability of the pressure head 1222 during the crimping process. Moreover, increasing the distance between the two connecting shafts 1221 can reserve more space for avoidance, and the connecting shaft 1221 will not collide with other elements during the test process, and since the volume of the two connecting shafts 1221 is reduced, the connecting shaft 1221 can be arranged in a narrow space for testing the test piece 122, thereby better realizing the miniaturization design of the crimping mechanism 100.

[0048] Since the aspect ratio of the connecting shaft 1221 is large, that is, the connecting shaft 1221 is an elongated shaft, the connecting shaft 1221 is prone to shaking during the movement of the connecting shaft 1221 relative to the bottom plate 1213, which causes the crimping position between the pressure head 1222 and the product under test 200 to deviate. Based on this, in an embodiment, referring to Figures 1-3 As shown, the end of the connecting shaft 1221 away from the pressure head 1222 is provided with a counterweight 1224, that is, the pressure head 1222 is arranged at one end of the connecting shaft 1221, and the counterweight 1224 is arranged at the other end of the connecting shaft 1221. The counterweight 1224 can be a weight, a metal block or the like element having a certain mass. In this way, by adding the counterweight 1224 to the connecting shaft 1221, the overall weight of the test piece 122 can be increased, so as to improve the stability of the connecting shaft 1221 during the movement of the connecting shaft 1221 relative to the bottom plate 1213, ensure the accurate alignment of the crimping position between the pressure head 1222 and the product under test 200, and further improve the test reliability of the crimping module 120 for the product under test 200.

[0049] Further, referring to Figures 1-3As shown, the counterweight 1224 is provided with a buffer 1226 on the side close to the body 121. After the test piece 122 is arranged behind the body 121, the counterweight 1224 is close to the top plate 1211. The buffer 1226 can be arranged at the end of the counterweight 1224 close to the top plate 1211. The buffer 1226 can buffer the contact impact force between the connecting shaft 1221 and the top plate 1211 during the movement, so as to avoid the deformation and fracture of the connecting shaft 1221 during the repeated impact on the top plate 1211, and protect the test piece 122.

[0050] The counterweight screw 1225 of the counterweight 1224 contacts the buffer 1226, so as to avoid the loosening of the counterweight screw 1225 during the continuous impact on the top plate 1211. In the embodiment, the buffer 1226 is a buffer foam, which is fixed to the counterweight 1224 by means of sticking, locking and the like, so as to realize the fixation of the buffer 1226 to the counterweight 1224.

[0051] In an embodiment, referring to Figures 1-3 As shown, at least one elastic member 1227 is further arranged between the connecting shaft 1221 and the pressure head 1222. The elastic member 1227 buffers the abutting force of the pressure head 1222 abutting against the product 200, so that the pressure head 1222 and the product 200 are in a flexible floating pressure connection, and the instantaneous force applied by the pressure head 1222 to the product 200 is prevented from being too large to damage the product 200. When the elastic member 1227 is a plurality of elastic members 1227, the plurality of elastic members 1227 are arranged in a circumferential direction of the pressure head 1222. The plurality of elastic members 1227 buffer the abutting force in cooperation, so as to improve the buffering reliability of the elastic member 1227. When one of the elastic members 1227 is deformed and damaged, the other elastic members 1227 can still function, so as to reduce the use cost of the pressure connection mechanism 100.

[0052] In the embodiment, the elastic member 1227 can be a return spring. Of course, in other feasible embodiments, the elastic member 1227 can also be an elastic sheet or other elastic element. The specific type of the elastic member 1227 is not limited in the application. In addition, the number of the elastic member 1227 can be four, six or other numbers. The specific number of the elastic member 1227 is also not limited in the application.

[0053] In an embodiment, referring to Figures 1-3As shown, the crimping module 120 comprises a signal conducting wire 1228.
