For example, during the testing of products such as VR glasses and semiconductor chips, the product to be tested is typically placed in a carrier, which is connected to a crimping cover plate that rotates. When the cover plate rotates to a first position where it electrically contacts the product to be tested, the crimping unit on the cover plate makes electrical contact with the product to perform an electrical crimping test on the product to be tested. When the cover plate rotates in the opposite direction to a second position where it is separated from the product to be tested, the product to be tested can be placed, retrieved, or replaced.

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

[0039] See Figure 1-Figure 3 As shown, the present application provides a cover closing mechanism 100, which includes a frame 110 and a cover pressing assembly 120. The cover closing mechanism 100 is used to cover the cover plate 300 on the carrier 200. The carrier 200 is used to carry the product 400 to be tested (such as a chip module, a wearable module, etc.). One end of the cover plate 300 is rotatably arranged on the carrier 200. The cover plate 300 has a first state and a second state. Figure 2 As shown, when the cover 300 is in the first state, the cover 300 is separated from the carrier 200. Figure 3 As shown, when the cover plate 300 is in the second state, the cover plate 300 is attached to the carrier 200 . That is, the cover plate 300 can be switched between the first state and the second state by rotating the cover plate 300 relative to the carrier 200 .

[0040] The cover pressing assembly 120 is movably mounted on the frame 110, and during the movement of the cover pressing assembly 120, the cover pressing assembly 120 can abut the side of the cover plate 300 away from the carrier 200. In other words, during the movement of the cover pressing assembly 120, the cover pressing assembly 120 can apply an abutting force to the cover plate 300, causing the cover plate 300 to rotate relative to the carrier 200, thereby switching the cover plate 300 from the first state to the second state, thereby achieving rotational covering of the cover plate 300 on the carrier 200. For example, when there is only one cover plate 300 on the carrier 200, the cover pressing assembly 120 moves relative to the frame 110 to a position where it can abut the side of the cover plate 300 away from the carrier 200, and continuously applies an abutting force to the cover plate 300 during the movement, thereby achieving rotational covering of the cover plate 300. When there are multiple cover plates 300 on the carrier 200, or multiple carriers 200 all have cover plates 300, and the orientations of the multiple cover plates 300 (such as the position of the cover plates 300, the direction in which the cover plates 300 are opened relative to the carrier 200, etc.) are different, the cover pressing assembly 120 moves to the corresponding cover plates 300 relative to the frame 110, and the cover pressing assembly 120 can apply abutting forces to the corresponding cover plates 300 in different orientations to achieve rotational covering of multiple cover plates 300 in different orientations.

[0041] The above-mentioned closing mechanism 100 applies a force to the cover plate 300 during the movement through the cover pressing assembly 120, automatically completes the closing operation of the cover plate 300, reduces the labor intensity of the closing operation of the cover plate 300, and completes the automatic closing of the cover plate 300 by mechanical means, which can ensure the consistency of the closing action of the cover plate 300, improve the closing efficiency and closing quality of the cover plate 300, and through the movement of the cover pressing assembly 120 relative to the frame 110, it can realize the rotational closing of multiple cover plates 300 in different orientations.

[0042] In one embodiment, continue to refer to Figure 4 and Figure 5 As shown, the cover pressing assembly 120 includes a roller 121 and a mounting plate 122. The mounting plate 122 is movably mounted on the frame 110 to movably mount the cover pressing assembly 120 on the frame 110. The roller 121 is rotatably mounted on the mounting plate 122. During the movement of the mounting plate 122, the roller 121 can roll against the cover plate 300. In other words, the roller 121 can apply a rolling pressing force to the cover plate 300 during the rolling process, causing the cover plate 300 to rotate relative to the carrier 200, thereby switching the cover plate 300 from the first state to the second state, thereby achieving rotational covering of the cover plate 300 on the carrier 200. Moreover, since the roller 121 is rotatably arranged on the mounting plate 122, when the roller 121 rolls and presses against the cover plate 300, the roller 121 and the cover plate 300 are in high-pair contact, which can reduce the friction and scratches of the roller 121 on the cover plate 300 during the rotation of the cover plate 300, thereby avoiding damage to the cover plate 300 by the roller 121.

[0043] Further, see Figure 1-Figure 5 As shown, the cover assembly 120 further includes a connecting plate 123. The connecting plate 123 is movably mounted on the frame 110 to movably mount the cover assembly 120 on the frame 110. The mounting plate 122 is movably mounted on the connecting plate 123. Since the roller 121 is connected to the mounting plate 122, the position of the roller 121 can be adjusted by the movement of the mounting plate 122 relative to the connecting plate 123. When the cover assembly 120 moves relative to the frame 110, the roller 121 is adapted to the position of the cover plate 300. The roller 121 can roll and abut against the cover plate 300, thereby performing a rotational closing operation on the cover plate 300.

[0044] Further, see Figure 1-Figure 5 As shown, the cover closing mechanism 100 further includes an adjustment assembly (not shown). The adjustment assembly is used to adjust the relative position of the mounting plate 122 and the connecting plate 123 to adjust the position of the roller 121 so that the roller 121 is adapted to the position of the cover plate 300. During the movement of the cover pressing assembly 120 relative to the frame 110, the roller 121 can abut against the cover plate 300 to perform a rotational closing operation on the cover plate 300.

[0045] Among them, continue to refer to Figure 6 As shown, the adjustment assembly includes a connector (not shown in the figure), which is used to connect the mounting plate 122 to the connecting plate 123. Exemplarily, the connector can be a connecting element such as a bolt or a hook, so that the mounting plate 122 can be connected to the connecting plate 123 through the connector. The mounting plate 122 is provided with a waist-shaped groove 1221. Preferably, the waist-shaped groove 1221 is integrally formed on the mounting plate 122 by injection molding, extrusion, etc., so as to simplify the molding process of opening the waist-shaped groove 1221 on the mounting plate 122. The connecting plate 123 is provided with a plurality of connecting holes 1231. Preferably, the connecting holes 1231 are integrally formed on the connecting plate 123 by injection molding, extrusion, etc., so as to simplify the molding process of opening the connecting holes 1231 on the connecting plate 123. The plurality of connecting holes 1231 are spaced apart along the extension direction of the waist-shaped groove 1221, and the orthographic projections of the plurality of connecting holes 1231 in the waist-shaped groove 1221 are located inside the waist-shaped groove 1221. Exemplarily, refer to Figure 6 As shown, the waist groove 1221 extends longitudinally along the length direction (along Figure 6 As shown, the plurality of connection holes 1231 extend in the vertical direction. Figure 6 The connecting piece is passed through the waist-shaped groove 1221 and connected to any one of the connecting holes 1231 .

[0046] When the position of the roller 121 of the lid closing mechanism 100 needs to be adjusted, the connection between the mounting plate 122 and the connecting plate 123 by the connecting member can be released, and the connecting member can be connected to the corresponding connecting hole 1231. This allows the position of the roller 121 to be adjusted so that the position of the roller 121 and the cover plate 300 are compatible. The minimum position adjustment of the roller 121 is defined by two adjacent connecting holes 1231, and the number of connecting holes 1231 can correspond to multiple adjustment positions. In other words, the number of connecting holes 1231 and the spacing between two adjacent connecting holes 1231 can be adaptively set based on the minimum position adjustment of the roller 121 and the number of adjustment positions, and this application does not impose any restrictions thereon.

[0047] In one embodiment, see Figure 1-Figure 4 As shown, the cover closing mechanism 100 further includes a moving assembly 130, which is mounted on the frame 110 by welding, screwing, or the like. The moving assembly 130 is configured to move the cover pressing assembly 120 in multiple directions. For example, the cover pressing assembly 120 is transmission-connected to the moving assembly 130, and the moving assembly 130 enables the cover pressing assembly 120 to move relative to the frame 110, so that the cover pressing assembly 120 can exert an abutting force on the cover plate 300 during movement, and the cover plate 300 rotates relative to the carrier 200 to switch the cover plate 300 from a first state to a second state, thereby achieving rotational closing of the cover plate 300 on the carrier 200.

[0048] It should be noted that, in this embodiment, the moving component 130 can be moved along Figure 1 and Figure 4 The cover pressing assembly 120 is moved in the three directions of X, Y, and Z. In other feasible embodiments, the moving assembly 130 is not limited to the above three moving directions, and can also be moved in other directions, as long as the moving assembly 130 can apply abutting force on the cover plate 300 during the process of moving the cover pressing assembly 120.

[0049] Specifically, see Figure 1-Figure 4 As shown, the moving assembly 130 includes an X-axis module 131, a Y-axis module 132 and a Z-axis module 133. The X-axis module 131 is connected to the cover assembly 120 in a transmission manner. The X-axis module 131 is used to drive the cover assembly 120 to move along the axis of the moving assembly 130. Figure 1 and Figure 4 The Y-axis module 132 is connected to the cover assembly 120, and the Y-axis module 132 is used to drive the cover assembly 120 along the Figure 1 and Figure 4 The Z-direction module 133 is connected to the gland assembly 120, and the Z-direction module 133 is used to drive the gland assembly 120 along Figure 1 and Figure 4Thus, through the cooperation of the X-axis module 131, the Y-axis module 132, and the Z-axis module 133, the cover pressing assembly 120 can be moved in three-dimensional space, and the cover pressing assembly 120 can apply abutting force to the cover plate 300 during the movement, so that the cover plate 300 rotates relative to the carrier 200, thereby switching the cover plate 300 from the first state to the second state, and realizing the rotational covering of the cover plate 300 on the carrier 200.

[0050] Further, see Figure 1-Figure 4 As shown, the Y-axis module 132 is arranged on the frame 110 by welding, screwing, etc. to realize the mobile installation of the cover assembly 120 on the frame 110; the X-axis module 131 is arranged on the Y-axis module 132 for sliding along the Y-axis, such as the X-axis module 131 is transmission-connected to the Y-axis module 132, and the X-axis module 131 can be driven to slide along the Y-axis through the Y-axis module 132; the Z-axis module 133 is arranged on the X-axis module 131 for sliding along the X-axis, such as the Z-axis module 133 is transmission-connected to the X-axis module 131, and the Z-axis module 133 can be driven to slide along the X-axis through the X-axis module 131; the cover assembly 120 is transmission-connected to the Z-axis module 133. In this way, by sliding the X-direction module 131 on the Y-direction module 132, the pressure cover assembly 120 can be driven to move along the Y-direction, and by sliding the Z-direction module 133 on the X-direction module 131, the pressure cover assembly 120 can be driven to move along the X-direction. Since the pressure cover assembly 120 is transmission-connected to the Z-direction module 133, the pressure cover assembly 120 can be driven to move along the Z-direction through the Z-direction module 133.

[0051] Further, see Figure 1-Figure 4As shown, the Z-direction module 133 includes a first Z-direction module 1331 and a second Z-direction module 1332. The first Z-direction module 1331 is slidably disposed on the X-direction module 131 along the X-direction, the second Z-direction module 1332 is transmission-connected to the first Z-direction module 1331, and the gland assembly 120 is transmission-connected to the second Z-direction module 1332. The first Z-direction module 1331 allows the gland assembly 120 to be slidably disposed on the X-direction module 131 along the X-direction, thereby driving the movement of the gland assembly 120 in the X-direction. Since the second Z-direction module 1332 is transmission-connected to the first Z-direction module 1331, the position of the gland assembly 120 in the Z-direction height direction can be coarsely adjusted via the first Z-direction module 1331, and the position of the gland assembly 120 in the Z-direction height direction can be fine-tuned via the second Z-direction module 1332. For example, when the specifications of the cover 300 to be covered change, the position of the cover assembly 120 can be pre-adjusted by the first Z-direction module 1331 to adapt to the covering action of cover plates 300 of different specifications; and since the cover assembly 120 will rotate relative to the carrier 200 during the process of abutting the cover 300, the position of the cover 300 in the Z direction will change during the rotation. The position of the cover assembly 120 can be adjusted by the second Z-direction module 1332 to ensure that the roller 121 is always in abutment with the side of the cover 300 away from the carrier 200. The cover assembly 120 can always apply an abutting force to the cover 300 during the movement, thereby realizing the rotational covering of the cover 300 on the carrier 200.

[0052] In this embodiment, the X-axis module 131 and the Y-axis module 132 are combined modules of a slide rail and a drive source. Of course, in other feasible embodiments, the X-axis module 131 and the Y-axis module 132 can also be chain conveyors, belt conveyors, etc. This application does not limit the specific component types of the X-axis module 131 and the Y-axis module 132. In addition, in this embodiment, the first Z-axis module 1331 and the second Z-axis module 1332 are linear motors, hydraulic cylinders, electric cylinders, etc. The second Z-axis module 1332 is transmission-connected to the output end of the first Z-axis module 1331, and the gland assembly 120 is transmission-connected to the output end of the second Z-axis module 1332.

[0053] Also, see Figure 1-Figure 4 As shown, the present application also provides a crimping device (not shown), which includes a carrier 200, a cover plate 300 and a cover closing mechanism 100 as described above. The carrier 200 is used to carry the product to be tested 400 (such as a chip module, a wearable module, etc.). One end of the cover plate 300 is rotatably arranged on the carrier 200. The cover plate 300 has a crimping portion 310. During the rotation of the cover plate 300, the cover plate 300 has a first state and a second state, see Figure 2As shown, when the cover 300 is in the first state, the crimping portion 310 is separated from the product to be tested 400, which facilitates the operation of taking, placing and replacing the product to be tested 400. Figure 3 As shown, when the cover 300 is in the second state, the crimping portion 310 electrically contacts the product 400, and the crimping device can perform an electrical crimping test on the product 400. The cover closing mechanism 100 is used to switch the cover 300 from the first state to the second state.

[0054] The above-mentioned crimping device applies a force to the cover plate 300 during the movement of the cover assembly 120, and automatically completes the closing operation of the cover plate 300, so that the crimping device can perform electrical crimping testing on the product to be tested 400, reducing the labor intensity of the closing operation of the cover plate 300, and completing the automatic closing of the cover plate 300 by mechanical means, which can ensure the consistency of the closing action of the cover plate 300, so that when the cover plate 300 is in the second state, the crimping part 310 maintains good electrical contact with the product to be tested 400, thereby improving the testing efficiency of the crimping device for the product to be tested 400 and the reliability of the test results.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0056] The above-described embodiments merely represent several implementation methods of the present application. 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 a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
