[0015] In one of the embodiments, the sliding block is provided with a positioning hole.

[0016] The compression module is further provided with an elastic pin, when the sliding block moves to the second position, the elastic pin is inserted into the positioning hole.

[0038] The technical solutions provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

[0039] Referring to Figure 1 With Figure 2 As shown in the drawings, the present application provides a test fixture 100, which includes a carrier plate 110, a crimping module 120 and a foolproof assembly 130. The carrier plate 110 is used to carry a product to be tested, and the carrier plate 110 is provided with a first hook 111. The crimping module 120 is pivotally connected to the carrier plate 110, such as being rotatably connected to the carrier plate 110 through a rotating shaft. The crimping module 120 can be rotated between an open state and a closed state to perform pick-and-place and test operations on the product to be tested. The crimping module 120 is provided with a second hook 121, which can be clamped to the first hook 111 to lock the crimping module 120 in the closed state to perform electrical tests on the product to be tested. Moreover, a torsional spring 122 is provided on the rotating shaft, which facilitates the resetting of the crimping module 120 between the open state and the closed state. The foolproof assembly 130 is arranged on the carrier plate 110, and the foolproof assembly 130 can slide between a first position and a second position. In this embodiment, the product to be tested can be a display module for a mobile phone, a computer or a tablet, and the test fixture 100 can perform performance tests such as lighting and interface plugging on the product to be tested.

[0040] When the fool-proof component 130 is in the first position, the fool-proof component 130 blocks at least part of the first clamping hook 111, that is, when the fool-proof component 130 is in the first position, the orthographic projection of the fool-proof component 130 overlaps or covers the outside of the first clamping hook 111. At this time, the crimping die set 120 can be rotated to electrically connect with the product to be tested, and the first clamping hook 111 is clamped on the second clamping hook 121 to lock the crimping die set 120 in the closed state to test the product to be tested. When the fool-proof component 130 is in the second position, the fool-proof component 130 avoids the second clamping hook 121.

[0041] The test fixture 100 described above, when the product to be tested needs to be tested, places the product to be tested on the carrier plate 110, rotates the crimping die set 120 to clamp the first clamping hook 111 on the second clamping hook 121, locks the crimping die set 120 in the closed state and electrically connects with the product to be tested to test the product to be tested. Since the fool-proof component 130 is in the first position at this time, the fool-proof component 130 blocks at least part of the first clamping hook 111, and the operation of the fool-proof component 130 on the first clamping hook 111 is interfered, which avoids damage caused by manual misoperation of taking and placing the product to be tested without power off. After the product to be tested is tested, the product to be tested can be powered off during the sliding process of the fool-proof component 130 from the first position to the second position, and after the fool-proof component 130 slides to the second position, the fool-proof component 130 avoids the first clamping hook 111, and the operator can perform the unlocking operation of the first clamping hook 111 and the second clamping hook 121, rotate the crimping die set 120 to the open state and take out the tested product to be tested. Since the fool-proof component 130 is in the first position during testing, the unlocking operation of the first clamping hook 111 and the second clamping hook 121 is interfered, and after the product to be tested is tested, the fool-proof component 130 needs to be slid from the first position to the second position, and the product to be tested is powered off during the sliding process, so that the taking and placing operation of the product to be tested can be performed, avoiding the phenomenon of hot plug of the product to be tested during testing.

[0042] In an embodiment, referring to Figure 1 and Figure 2As shown, the test fixture 100 further comprises a control assembly 140, which controls the power-off of the product under test in response to the sliding of the fool-proof assembly 130 from the first position to the second position. For example, after the product under test is tested, at this time, the fool-proof assembly 130 is in the first position, the unlocking action of the first hook 111 and the second hook 121 cannot be immediately performed, the sliding action of the fool-proof assembly 130 from the first position to the second position needs to be performed, and during the sliding of the fool-proof assembly 130 from the first position to the second position, the control assembly 140 controls the power-off of the product under test, so that after the fool-proof assembly 130 slides to the second position, the product under test is powered off, the fool-proof assembly 130 avoids the first hook 111, the unlocking action of the first hook 111 and the second hook 121 is performed, the product under test is taken and placed, and the adverse phenomenon of hot plug of the product under test in the testing process is avoided.

[0043] Specifically, referring to Figure 1 and Figure 2 As shown, the control assembly 140 comprises a sensing element 141 and a control element (not shown in the figure), and the control element is in communication connection with the sensing element 141. The sensing element 141 is used for sensing the position of the fool-proof assembly 130, and the control element is used for controlling the power-off of the product under test. For example, when the sliding action of the fool-proof assembly 130 from the first position to the second position is performed, the sensing element 141 senses the position change of the fool-proof assembly 130, feeds back the position change signal of the fool-proof assembly 130 to the control element, and the control element controls the power-off of the product under test. The power-off control operation of the product under test is associated with the position sliding operation of the fool-proof assembly 130, the power-off operation of the product under test can be automatically implemented during the sliding process of the fool-proof assembly, and the adverse phenomenon of hot plug of the product under test in the testing process is avoided.

[0044] Among them, the sensing element 141 can be an infrared sensor, a position sensor or other elements capable of obtaining position change information, and the control element can be a programmable logic controller (PLC), a micro control unit (MCU) or other elements capable of controlling the on-off of a circuit. The specific element type of the sensing element 141 and the control element is not limited in the present application.

[0045] In an embodiment, referring to Figure 1 and Figure 2As shown, the fool-proof assembly 130 comprises a sliding seat 131 and a sliding block 132. The sliding seat 131 is arranged on the carrier plate 110 to realize mounting and fixing of the fool-proof assembly 130, and the sliding block 132 is slidingly arranged in the sliding seat 131. When the sliding block 132 slides to the first position, the sliding block 132 blocks at least part of the first clamping hook 111, and the sliding block 132 interferes with the unlocking operation of the first clamping hook 111 and the second clamping hook 121, so as to avoid damage caused by taking and placing the to-be-tested product without power-off due to manual misoperation. When the sliding block 132 slides to the second position, the sliding block 132 avoids the first clamping hook 111, and the operator can perform the unlocking operation of the first clamping hook 111 and the second clamping hook 121, rotate the crimping module 120 to the open state, and take out the to-be-tested product after testing, so as to avoid the phenomenon of hot plugging of the to-be-tested product in the testing process.

[0046] For example, the first clamping hook 111 has an operation portion 1111 which protrudes to the outside of the carrier plate 110, and the operator can press, push or pull the operation portion 1111 to rotate the first clamping hook 111, so that the first clamping hook 111 and the second clamping hook 121 are switched from the locked state to the unlocked state, facilitating taking and placing the to-be-tested product after testing.

[0047] Further, continuing to refer to Figure 3 and Figure 4 As shown, the fool-proof assembly 130 further comprises a first elastic member 133. The first elastic member 133 is arranged between the sliding seat 131 and the sliding block 132, for example, one end of the first elastic member 133 abuts against the sliding seat 131, and the other end of the first elastic member 133 abuts against the sliding block 132. The deformation direction of the first elastic member 133 is consistent with the movement direction of the sliding block 132, and when the first elastic member 133 is not subjected to external force, the sliding block 132 is located at the first position. For example, after testing of the to-be-tested product is completed, the sliding block 132 is at the first position, the sliding block 132 interferes with the operation of the first clamping hook 111, and the unlocking operation of the first clamping hook 111 and the second clamping hook 121 cannot be performed. The operator presses, pushes or pulls the sliding block 132 to move the sliding block 132 from the first position to the second position, the first elastic member 133 is compressed, and in the process of sliding the sliding block 132 from the first position to the second position, the control assembly 140 controls power-off of the to-be-tested product. After the sliding block 132 slides to the second position, the sliding block 132 avoids the first clamping hook 111, and the unlocking operation of the first clamping hook 111 and the second clamping hook 121 can be performed to rotate the crimping module 120 to the open state to take and place the to-be-tested product. After the to-be-tested product is taken and placed, the first elastic member 133 is elastically reset to push the sliding block 132 from the second position to the first position, and the testing operation of the to-be-tested product is continued.

[0048] In the embodiment, the first elastic member 133 is a return spring, which is elastically deformed and elastically returns to drive the slider 132 to move between the first position and the second position. Of course, in other possible embodiments, the first elastic member 133 can also be an elastic sheet or other elastic element, and the specific type of the first elastic member 133 is not limited in the application.

[0049] Specifically, referring to Figure 1 、 Figure 2 and Figure 4 , the slider 132 is provided with a positioning hole 1321. Preferably, the positioning hole 1321 is formed on the slider 132 by injection molding, extrusion or other methods to simplify the forming process of the positioning hole 1321 on the slider 132. The crimping module 120 is also provided with an elastic pin 123. When the slider 132 moves to the second position, the positioning hole 1321 is aligned with the elastic pin 123, the elastic pin 123 extends and is inserted into the positioning hole 1321 to lock the slider 132 at the second position for the unlocking action of the first and second clamping hooks 111 and 121, which facilitates the operator to perform the unlocking action.

[0050] In an embodiment, referring to Figure 1 and Figure 2 , the first clamping hook 111 is movably arranged on the carrier plate 110 and can slide between a third position and a fourth position. When the first clamping hook 111 slides to the third position, the first clamping hook 111 avoids the second clamping hook 121, so that the clamping part of the first clamping hook 111 can move to a position matched with the clamping part of the second clamping hook 121. When the first clamping hook 111 slides to the fourth position, the first clamping hook 111 can be clamped on the second clamping hook 121, so that the first clamping hook 111 and the second clamping hook 121 are clamped, and the crimping module 120 is in a locked state for electrical testing of the product under test.

[0051] Further, referring to Figure 1 、 Figure 2 and Figure 5 , the test fixture 100 further includes a second elastic member 150. The second elastic member 150 is arranged between the first clamping hook 111 and the carrier plate 110, such as one end of the second elastic member 150 abutting against the carrier plate 110, and the other end of the second elastic member 150 abutting against the first clamping hook 111. The deformation direction of the second elastic member 150 is consistent with the movement direction of the first clamping hook 111, and when the second elastic member 150 is not subjected to external force, the first clamping hook 111 is located at the fourth position. In the embodiment, referring to Figure 5 , the operator presses the crimping module 120 towards the C direction shown in Figure 5 , the crimping module 120 rotates relative to the carrier plate 110, and the clamping part of the second clamping hook 121 abuts against the clamping part of the first clamping hook 111 during the movement to pushFigure 5 The left first clamping hook 111 moves from the fourth position to the third position towards the D direction, the second elastic member 150 is compressed, the first clamping hook 111 avoids the second clamping hook 121, and the second clamping hook 121 continues to move along the C direction as shown. Figure 5 After the second clamping hook 121 continues to move along the C direction as shown to a position where it can be clamped with the first clamping hook 111, the second elastic member 150 is elastically reset, Figure 5 The left first clamping hook 111 moves from the third position to the fourth position towards the E direction and cooperates with the second clamping hook 121 to limit the crimping module 120 in the locking state for electrical testing of the product to be tested.

[0052] In this embodiment, the second elastic member 150 is a reset spring, and the elastic deformation and elastic reset of the second elastic member 150 drive the first clamping hook 111 to move between the third position and the fourth position. Of course, in other possible embodiments, the second elastic member 150 can also be an elastic sheet or other elastic element, and the specific type of the second elastic member 150 is not limited in this application.

[0053] Preferably, the first clamping hook 111 and the second clamping hook 121 are both multiple, and the multiple first clamping hooks 111 are arranged at intervals along the circumferential direction of the carrier plate 110, and the multiple second clamping hooks 121 are arranged at intervals along the circumferential direction of the crimping module 120. The clamping and cooperation of the multiple first clamping hooks 111 and the second clamping hooks 121 can improve the closure reliability of the crimping module 120 and the carrier plate 110, and further improve the testing reliability of the product to be tested. For example, in this embodiment, the first clamping hook 111 is two, and the second clamping hook 121 is also two, and the two first clamping hooks 111 are arranged on opposite sides of the carrier plate 110, and the two second clamping hooks 121 are arranged on opposite sides of the crimping module 120. Of course, in other possible embodiments, the first clamping hook 111 and the second clamping hook 121 can also be other quantities, and the specific number and arrangement position of the first clamping hook 111 and the second clamping hook 121 are not limited in this application.

[0054] In an embodiment, referring to Figure 1 and Figure 2 As shown, the crimping module 120 includes a pressing plate 124 and a test member 125 arranged on the pressing plate 124, such as a test probe, a test interface, etc. The carrier plate 110 is provided with a bearing cavity 112 for bearing the product to be tested. Preferably, the bearing cavity 112 is a profiling cavity to improve the convenience and reliability of placing the product to be tested. When the product to be tested is placed in the bearing cavity 112 and the first clamping hook 111 is clamped in the second clamping hook 121, the crimping module 120 is locked in the closed state, the test member 125 is electrically connected to the product to be tested, and the test member 125 can perform performance testing such as lighting and interface plugging on the product to be tested.

[0055] In addition, referring to Figures 1-5 The application further provides a test device, which comprises the test fixture 100 of the above technical solution. The test device can perform performance tests such as lighting and interface plugging on the product to be tested.

[0056] The test device described above, because the foolproof component 130 is in the first position during the test process, the unlocking operation of the first clamping hook 111 and the second clamping hook 121 is interfered, and after the test of the product to be tested is completed, the foolproof component 130 needs to be slid from the first position to the second position, and during the sliding process, the power supply to the product to be tested is turned off, so that the taking and placing operations of the product to be tested can be performed, thereby avoiding the adverse phenomenon of hot plugging of the product to be tested during the test process.

[0057] The following will be described in detail Figures 1-5 The test operation of the product to be tested in the application will be described in detail.

[0058] First, the crimping module 120 is rotated to the open state, and the product to be tested is placed on the carrier plate 110; then, the operator acts on the crimping module 120 in the pressing, pushing, and dialing manner along Figure 5 The crimping module 120 rotates relative to the carrier plate 110, and the clamping part of the second clamping hook 121 abuts against the clamping part of the first clamping hook 111 during the rotation process, pushing the first clamping hook 111 to move along the C direction. Figure 5 The left first clamping hook 111 moves along the D direction from the fourth position to the third position, and the second elastic member 150 is compressed, and the first clamping hook 111 avoids the second clamping hook 121, and the second clamping hook 121 continues to move along the C direction. Figure 5 After the second clamping hook 121 continues to move along the C direction to a position where it can be clamped with the first clamping hook 111, the second elastic member 150 is elastically reset, Figure 5 The left first clamping hook 111 moves along the E direction from the third position to the fourth position and cooperates with the second clamping hook 121, and the crimping module 120 is locked in the closed state and electrically connected with the product to be tested, so as to perform electrical test on the product to be tested; then, after the test of the product to be tested is completed, because the sliding block 132 is in the first position, the sliding block 132 blocks at least part of the first clamping hook 111, and the unlocking operation of the first clamping hook 111 and the second clamping hook 121 cannot be immediately performed, at this time, the operator acts on the sliding block 132 in the pressing, dialing, and pushing manner, so that the sliding block 132 moves from the first position to the second position, the first elastic member 133 is compressed, and during the sliding process of the sliding block 132 from the first position to the second position, the control component 140 controls the power supply to the product to be tested to be turned off, the unlocking operation of the first clamping hook 111 and the second clamping hook 121 can be performed, and the crimping module 120 is rotated to the open state to take and place the product to be tested; finally, after the taking and placing of the product to be tested are completed, the first elastic member 133 is elastically reset to push the sliding block 132 to move from the second position to the first position, and the test operation of the product to be tested is continued.
