Description

Technical Field

[0001] This application relates to the field of product testing technology, and in particular to a flipping mechanism, testing device and equipment. Background Technology

[0002] With the development of electronic components such as semiconductors, display panels, and wearable watches, electrical tests are required during the manufacturing process of electronic components to ensure that their performance meets the preset requirements.

[0003] Currently, in the process of electrical testing of electronic components, the product under test (DUT) is typically placed in a test fixture, and the test fixture, along with the DUT, is loaded into the testing machine for electrical testing. However, during the placement of the DUT, the test fixture usually involves opening and closing its lid. This repeated opening and closing can easily damage the test fixture, and since the opening and closing of individual test fixtures can only be done manually, the efficiency of opening and closing the test fixture is too low. Utility Model Content

[0004] Therefore, it is necessary to provide a flipping mechanism, testing device and equipment to address the problems of existing test fixtures being easily damaged during the opening and closing process and having low opening and closing efficiency.

[0005] A flipping mechanism is used for opening and closing the covers of multiple test fixtures. The test fixtures include a carrier plate and a cover plate rotatably disposed on the carrier plate. The carrier plate has a locking portion, and the cover plate has a hook portion that can engage with the locking portion. The flipping mechanism includes:

[0006] The drive assembly and multiple opening and closing cover assemblies include a push module. The drive assembly and the multiple push modules are all drive-connected. The push module responds to the power output of the drive assembly and abuts against the side of the cover plate away from the carrier plate to push the hook part to engage or disengage with the engaging part.

[0007] In one embodiment, the drive assembly includes a drive source and an output shaft rotatably connected to the output end of the drive source;

[0008] The pushing module includes a power source and a pushing component connected to the power source. The power source is located on the output shaft and is used to drive the pushing component to move toward the side of the cover plate away from the carrier plate.

[0009] In one embodiment, the opening and closing cover assembly further includes a Z-axis module, which is drively connected to the test fixture and is used to drive the test fixture to move toward or away from the push module.

[0010] In one embodiment, the opening and closing cover assembly further includes a transverse module, which is tractively connected to the test fixture and is used to drive the test fixture to move in the XY plane.

[0011] In one embodiment, a plurality of the power sources are spaced apart on the output shaft along the extension direction of the output shaft.

[0012] In one embodiment, the opening and closing cover assembly further includes a mounting base, through which the power source is disposed on the output shaft.

[0013] A testing apparatus, the testing apparatus comprising:

[0014] Multiple test fixtures, each test fixture including a carrier plate and a cover plate rotatably disposed on the carrier plate, the carrier plate having a locking portion, and the cover plate having a hook portion capable of engaging with the locking portion; and

[0015] The flipping mechanism described in any of the above technical solutions is used for opening and closing the covers of the plurality of test fixtures.

[0016] In one embodiment, the engaging portion is rotatably disposed on the cover plate, and an elastic element is provided between the hook portion and the cover plate.

[0017] A testing device, the testing device comprising:

[0018] The testing device as described in any of the above technical solutions.

[0019] In one embodiment, the testing equipment further includes:

[0020] Machine tool;

[0021] The testing organization, located on the machine, is used to test the product under test; and

[0022] The loading and unloading mechanism is used to feed the testing device carrying the product to be tested to the testing mechanism, and to unload the product to be tested after testing.

[0023] The aforementioned flipping mechanism, testing device, and equipment drive the drive component to output power and drive the push module to abut against the side of the cover plate away from the carrier plate, thereby pushing the cover plate to rotate around the carrier plate. When the push module pushes the hook part to engage with the engaging part, the cover plate closes to the carrier plate, realizing the closing operation of the test fixture. When the push module pushes the hook part to disengage from the engaging part, it realizes the opening operation of the test fixture. The flipping mechanism provided in this application, in which the push module pushes the hook part to engage or disengage from the engaging part, can realize the opening and closing operation of multiple test fixtures, improving the opening and closing efficiency of the test fixtures. Moreover, the flipping mechanism automatically realizes the opening and closing operation of the test fixtures, resulting in high consistency in the opening and closing operation of the test fixtures and making the test fixtures less prone to damage during the opening and closing operation.

[0044] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0045] See Figures 1-3 As shown, this application provides a flipping mechanism 100, which includes a drive assembly 110 and multiple opening and closing cover assemblies 120. The flipping mechanism 100 is used for opening and closing the cover of a test fixture 200. The test fixture 200 includes a carrier plate 210 and a cover plate 220. The cover plate 220 is rotatably disposed on the carrier plate 210. For example, one side of the cover plate 220 is rotatably connected to the carrier plate 210 by a rotating pin. When the cover plate 220 is closed on the carrier plate 210, a bearing space for bearing the product to be tested is formed between the cover plate 220 and the carrier plate 210. The carrier plate 210 has a locking portion 211, and the cover plate 220 has a hook portion 221. The hook portion 221 can engage or disengage with the locking portion 211. For example, the locking portion 211 can be a pin on the carrier plate 210, and the hook portion 221 can be a hook on the cover plate 220. The hook has a groove that can cooperate with the pin. When the hook portion 221 engages with the locking portion 211, the cover plate 220 covers the carrier plate 210. When the hook portion 221 disengages from the locking portion 211, the cover plate 220 opens relative to the carrier plate 210. In this embodiment, the product under test can include, but is not limited to, electronic components such as semiconductors, display panels, and wearable watches.

[0046] The opening and closing assembly 120 includes a push module 121, and a drive assembly 110 is tractively connected to multiple push modules 121. The push module 121 abuts against the side of the cover plate 220 opposite to the carrier plate 210 in response to the power output of the drive assembly 110. The push module 121 is used to push the hook portion 221 to engage or disengage with the engaging portion 211. For example, the drive assembly 110 outputs power and drives the push module 121 to abut against the side of the cover plate 220 opposite to the carrier plate 210, thereby pushing the cover plate 220 to rotate around the carrier plate 210. When the push module 121 pushes the hook portion 221 to engage with the engaging portion 211, the cover plate 220 closes onto the carrier plate 210, enabling a closing operation for the test fixture 200. When the push module 121 pushes the hook portion 221 to disengage from the engaging portion 211, an opening operation for the test fixture 200 is achieved.

[0047] The aforementioned flipping mechanism 100 pushes the module 121 to engage or disengage the hook portion 221 and the engaging portion 211. The flipping mechanism 100 can realize the opening and closing operations of multiple test fixtures 200, improve the opening and closing efficiency of the test fixtures 200, and the flipping mechanism 100 automatically realizes the opening and closing operations of the test fixtures 200. The opening and closing operations of the test fixtures 200 have high consistency, and the test fixtures 200 are not easily damaged during the opening and closing operations.

[0048] In one embodiment, see Figures 1-3 As shown, the drive assembly 110 includes a drive source 111 and an output shaft 112, with the output shaft 112 rotatably connected to the output end of the drive source 111. The push module 121 includes a power source 1211 and a pusher 1212, with the pusher 1212 and the power source 1211 being driveably connected. The power source 1211 is disposed on the output shaft 112 to realize the drive connection between the push module 121 and the drive assembly 110. The power source 1211 is used to drive the pusher 1212 to move toward the side of the cover plate 220 away from the carrier plate 210.

[0049] For example, in its normal state, the test fixture 200 has a cover plate 220 covering the carrier plate 210. When it is necessary to open or close the cover of the test fixture 200, firstly, the drive source 111 outputs power to the output shaft 112, the output shaft 112 rotates and drives the push module 121 to rotate. Figure 2The cover plate 220 is rotated in the V1 direction to a position where it can abut against the cover plate 220. Then, the power source 1211 outputs power to the pusher 1212, which moves toward the side of the cover plate 220 away from the carrier plate 210. During the continuous movement of the pusher 1212, the pusher 1212 applies abutting force to the cover plate 220 until the hook portion 221 separates from the engaging portion 211. Next, the drive source 111 outputs power to the output shaft 112, which rotates and drives the pusher module 121 to move toward a position where it avoids the cover plate 220 opening. The cover plate 220 moves along... Figure 2 The test fixture 200 is opened by rotating around the carrier plate 210 in the V2 direction, allowing the product to be tested to be placed in the bearing space between the carrier plate 210 and the cover plate 220. After the product is placed in the test fixture 200, the drive source 111 outputs power to the output shaft 112, which rotates and drives the push module 121 around the carrier plate 210. Figure 2 The cover plate 220 is rotated in the direction of V1 to a position where it can abut against the cover plate 220; finally, the power source 1211 outputs power to the pusher 1212, which moves toward the side of the cover plate 220 away from the carrier plate 210. During the continuous movement of the pusher 1212, the pusher 1212 applies abutting force to the cover plate 220, and the cover plate 220 moves along... Figure 2 The device rotates in the direction of V1 around the carrier plate 210 until the hook part 221 engages with the engaging part 211, thereby realizing the closing operation of the test fixture 200.

[0050] In this embodiment, the drive source 111 and the power source 1211 may include, but are not limited to, power components such as drive motors and drive cylinders. Furthermore, the pusher 1212 may be a rod-shaped member that is retractable relative to the power source 1211. The power output from the power source 1211 can drive the pusher 1212 to extend into or out of the power source 1211, thereby driving the pusher 1212 to move towards or away from the side of the cover plate 220 opposite to the carrier plate 210.

[0051] Since the travel distance of the drive member 1212 driven by the power source 1211 is limited, in one embodiment, see [reference] Figures 1-3 As shown, the opening and closing assembly 120 also includes a Z-axis module 123. The Z-axis module 123 is driveably connected to the test fixture 200 and is used to drive the test fixture 200 to move towards or away from the push module 121. Exemplarily, when the test fixture 200 is opened or closed, the power source 1211 outputs power to drive the pusher 1212 towards the side of the cover plate 220 away from the carrier plate 210. Because the push module 121 rotates around the cover during the opening and closing process... Figure 2The V1 direction rotation, i.e., the push module 121 moves along the arc trajectory, drives the test fixture 200 to move towards the push module 121 through the Z-axis module 123, compensating for the movement stroke of the push member 1212, so that the push member 1212 can always abut against the side of the cover plate 220 away from the carrier plate 210, ensuring that the push module 121 can apply abutting force to the cover plate 220, and complete the opening and closing operation of the test fixture 200.

[0052] Further, see Figures 1-3 As shown, the opening and closing cover assembly 120 also includes a lateral module 124. The lateral module 124 is drively connected to the test fixture 200 and is used to drive the test fixture 200 to move in the XY plane. Exemplarily, when the test fixture 200 is opened and closed, the power source 1211 outputs power to drive the pusher 1212 towards the side of the cover plate 220 away from the carrier plate 210. Because the pusher module 121 moves around the cover plate during the opening and closing process... Figure 2 The rotation in the V1 direction, i.e., the pushing module 121 moves along an arc-shaped trajectory, drives the test fixture 200 towards the pushing module 121 via the Z-axis module 123, and drives the test fixture 200 to move in the XY plane via the lateral module 124. The Z-axis module 123 and the lateral module 124 cooperate to compensate for the movement stroke of the pushing member 1212, so that the pushing member 1212 can always abut against the side of the cover plate 220 away from the carrier plate 210, ensuring that the pushing module 121 can apply abutting force to the cover plate 220, completing the opening and closing operation of the test fixture 200. Furthermore, for test fixtures 200 in different positions, the lateral module 124 can feed test fixtures 200 in different positions to the positions corresponding to the flipping mechanism 100, and the flipping mechanism 100 performs the opening and closing operation of test fixtures 200 in different positions.

[0053] In one embodiment, see Figures 1-4 As shown, multiple power sources 1211 are spaced apart on the output shaft 112 along its extension direction. Thus, by placing multiple push modules 121 on the drive assembly 110, during the power output process of the drive assembly 110, multiple push modules 121 can simultaneously complete the opening and closing operations of multiple test fixtures 200 in a single operation, thereby improving the opening and closing efficiency of the test fixtures 200.

[0054] Further, see Figures 1-3As shown, the opening and closing cover assembly 120 also includes a mounting base 125, through which the power source 1211 is mounted on the output shaft 112. Thus, the mounting base 125 enables the transmission connection between the push module 121 and the drive assembly 110. The mounting base 125 facilitates the installation layout of the push module 121, improving the connection stability and reliability between the push module 121 and the drive assembly 110 without altering the overall structure of the push module 121.

[0055] For example, the mounting base 125 is fixed to the output shaft 112 by means of screwing, snap-fitting, etc., and the power source 1211 is fixed to the mounting base 125 by means of screwing, snap-fitting, etc., and the transmission connection between the drive module 121 and the drive component 110 is realized through the mounting base 125.

[0056] Additionally, see Figures 1-4 As shown, this application also provides a testing device 300, which includes a plurality of testing fixtures 200 and a flipping mechanism 100 as described above. The flipping mechanism 100 is used for opening and closing the lids of the plurality of testing fixtures 200. The testing fixture 200 includes a carrier plate 210 and a cover plate 220. The cover plate 220 is rotatably disposed on the carrier plate 210. For example, one side of the cover plate 220 is rotatably connected to the carrier plate 210 by a rotating pin, and when the cover plate 220 is closed on the carrier plate 210, a bearing space for bearing the product to be tested is formed between the cover plate 220 and the carrier plate 210. The carrier plate 210 has a locking part 211, and the cover plate 220 has a hook part 221. The hook part 221 can engage or disengage with the locking part 211. When the hook part 221 engages with the locking part 211, the cover plate 220 covers the carrier plate 210. When the hook part 221 disengages from the locking part 211, the cover plate 220 opens relative to the carrier plate 210.

[0057] The aforementioned testing device 300 pushes the module 121 to engage or disengage the hook part 221 and the engaging part 211. The flipping mechanism 100 can realize the opening and closing operation of multiple test fixtures 200, improving the opening and closing efficiency of the test fixtures 200. Moreover, the flipping mechanism 100 automatically realizes the opening and closing operation of the test fixtures 200, resulting in high consistency in the opening and closing operation of the test fixtures 200 and making the test fixtures 200 less prone to damage during the opening and closing operation.

[0058] In one embodiment, see Figures 1-4As shown, the engaging portion 211 is rotatably mounted on the cover plate 220, and an elastic element 230 is provided between the hook portion 221 and the cover plate 220. If there is an installation gap between the hook portion 221 and the cover plate 220, the elastic element 230 is disposed within the installation gap, with one end of the elastic element 230 fixed to the cover plate 220 and the other end fixed to the hook portion 221. Thus, the hook portion 221 is elastically mounted on the cover plate 220. When an abutting force is applied to the cover plate 220, the elastic deformation of the elastic element 230 allows for elastic engagement or disengagement between the hook portion 221 and the engaging portion 211.

[0059] In this embodiment, the elastic element 230 is a spring. Through the elastic deformation of the spring, an elastic connection can be achieved between the hook portion 221 and the cover plate 220. Of course, in other feasible embodiments, the elastic element 230 can also be an elastic sheet or other elastic element. This application does not limit the specific type of elastic element 230.

[0060] Further, see Figures 1-3 As shown, the test fixture 200 also includes a pressure head 240, which is disposed on the side of the cover plate 220 facing the carrier plate 210. When the cover plate 220 is closed on the carrier plate 210, the pressure head 240 can be electrically pressed onto the product under test to perform an electrical pressing test on the product under test. Furthermore, the pressure head 240 integrates a heat dissipation unit to dissipate heat during the pressing test, ensuring the stability of the pressing test environment, improving the testing reliability of the test device 300, and extending the service life of the test device 300.

[0061] Additionally, see Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, this application also provides a test device 400, which includes a test apparatus 300 as described above. The test apparatus 300 is used to perform electrical tests on the product under test carried by the test apparatus 300.

[0062] In one embodiment, see Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the testing equipment 400 also includes a machine base 410, a testing mechanism 420, and a loading / unloading mechanism 430. The testing mechanism 420 is disposed on the machine base 410 and is used to test the product under test. The loading / unloading mechanism 430 is used to feed the testing device 300 carrying the product under test to the testing mechanism 420, and is also used to unload the product under test after testing. Exemplarily, the loading / unloading mechanism 430 includes a multi-axis conveying module 431, a lifting module 432, and a conveyor line 433. The multi-axis conveying module 431 is used to transport the testing device 300 to the conveyor line 433, the lifting module 432 is used to switch the testing device 300 between the loading position and the unloading position, and the conveyor line 433 is used for the transfer operation of the testing device 300 between the loading / unloading mechanism 430 and the testing mechanism 420. The testing unit 420 may include multiple testing units. These multiple testing units can be used for the same type of testing, such as aging testing units. They can also be used for different types of testing, such as aging testing units, lighting testing units, etc.

[0063] In the aforementioned testing equipment 400, firstly, the operator moves the product to be tested to the loading / unloading mechanism 430; then, the flipping mechanism 100 performs opening and closing operations on multiple testing fixtures 200 to place multiple products to be tested into multiple testing fixtures 200 respectively, and after the products to be tested are placed into the testing fixtures 200, the cover plate 220 closes onto the carrier plate 210; next, the conveyor line 433 feeds the testing device 300 carrying the products to be tested from the loading / unloading mechanism 430 to the testing mechanism 420; then, the testing mechanism 420 tests the products to be tested; continuing, the conveyor line 433 feeds the testing device 300 carrying the products to be tested from the testing mechanism 420 to the loading / unloading mechanism 430; finally, the loading / unloading mechanism 430 unloads the products to be tested from the testing device 300.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
