Description

Technical Field

[0001] The present application relates to the field of product testing technology, and in particular to a testing fixture and device. Background Art

[0002] VR glasses use head-mounted display devices to block a person's vision and hearing from the outside world, guiding the user to experience a virtual environment. The display principle is that the left and right eye screens display the left and right eye images respectively. The human eye receives this differential information and creates a three-dimensional perception in the mind. VR glasses require signal testing before leaving the factory to verify that the VR glasses can properly output the corresponding signals after receiving them. Because the left and right eye screens of VR glasses are symmetrical, they must be tested independently.

[0003] Currently, two methods are commonly used to test VR glasses: one is to set up two testing stations on the testing fixture, and place the left eye screen and the right eye screen on the two testing stations for electrical testing; the other is to use two testing fixtures to perform independent electrical testing on the left eye screen and the right eye screen. However, regardless of which testing method is used, the different testing environments of the left eye screen and the right eye screen lead to low reliability of the test results of the left and right eye screens of VR glasses.

[0041] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0042] See Figure 1-Figure 3 As shown, the present application provides a testing jig 100, which includes a carrier plate 110, a first cover plate 120, a second cover plate 130 and a testing assembly 140. The testing jig 100 is used to perform electrical testing on a first product 200 and a second product 300, and the first product 200 and the second product 300 are symmetrical structures. For example, in this embodiment, the testing jig 100 is used to perform electrical testing on VR glasses, the first product 200 is the left eye screen of the VR glasses, and the second product 300 is the right eye screen of the VR glasses. The left eye screen and the right eye screen can be electrically tested by the testing jig 100. Of course, in other feasible embodiments, the testing jig 100 can also be used to test other products with symmetrical structures such as dual screens. This application does not limit the specific testing products of the testing jig 100.

[0043] The carrier 110 has a cavity 111 for accommodating a first product 200 and a second product 300. For example, when the first product 200 needs to be inspected, the first product 200 can be placed in the cavity 111. Similarly, when the second product 300 needs to be inspected, the second product 300 can be placed in the cavity 111. Preferably, the cavity 111 is integrally formed with the carrier 110 by injection molding, extrusion, or the like, to simplify the molding process of the cavity 111 on the carrier 110.

[0044] The detection component 140 is disposed on the carrier 110 and is used to perform electrical testing on the first product 200 and the second product 300. Figure 1 and Figure 4 As shown, when the first product 200 is placed in the mold cavity 111, the detection component 140 is electrically connected to the first product 200 to perform electrical detection on the first product 200. Figure 2 and Figure 5 As shown, when the second product 300 is placed in the mold cavity 111, the detection assembly 140 is electrically connected to the second product 300. When testing the first product 200 and the second product 300, the above-mentioned detection fixture 100 can place the first product 200 or the second product 300 in the mold cavity 111. Because the first product 200 and the second product 300 share the mold cavity 111 and the detection assembly 140, the consistency of the detection environment of the first product 200 and the second product 300 can be ensured, thereby improving the reliability of the detection results of the first product 200 and the second product 300.

[0045] In one embodiment, see Figure 1-Figure 3 As shown, the inspection jig 100 further includes a first cover plate 120 and a second cover plate 130, one of which is detachably connected to the carrier plate 110, wherein the first cover plate 120 corresponds to the first product 200, and the second cover plate 130 corresponds to the second product 300. Since the first product 200 and the second product 300 are symmetrical structures, the cover plate structures required when fixing the first product 200 and the second product 300 are slightly different. In this embodiment, when the first product 200 is accommodated in the mold cavity 111, the first cover plate 120 is connected to the carrier plate 110 and pressed onto the first product 200, and when the second product 300 is accommodated in the mold cavity 111, the second cover plate 130 is connected to the carrier plate 110 and pressed onto the second product 300. That is to say, refer to Figure 1 and Figure 4 As shown, when the first product 200 needs to be inspected, the first cover plate 120 can be connected to the carrier plate 110, and the first product 200 can be pressed and fixed in the cavity 111 by the first cover plate 120 for inspection. Figure 2 and Figure 5 As shown, when the second product 300 needs to be inspected, the second cover plate 130 can be connected to the carrier plate 110, and the second product 300 can be pressed and fixed in the cavity 111 through the second cover plate 130 for inspection.

[0046] Exemplarily, the first cover plate 120 and the second cover plate 130 have magnetic adsorption properties. For example, at least a portion of the first cover plate 120 is made of a magnetic metal such as iron, cobalt, or nickel, and at least a portion of the second cover plate 130 is also made of a magnetic metal such as iron, cobalt, or nickel. The carrier plate 110 is provided with at least one magnetic member 112. The magnetic member 112 is used to adsorb the first cover plate 120 or the second cover plate 130 to the carrier plate 110, so as to achieve a detachable connection between the first cover plate 120 or the second cover plate 130 and the carrier plate 110. Preferably, the carrier plate 110 is provided with a plurality of magnetic members 112, which are arranged at intervals along the circumferential direction of the carrier plate 110. The plurality of magnetic members 112 can ensure the reliability of the connection between the first cover plate 120 or the second cover plate 130 and the carrier plate 110. Of course, in other feasible embodiments, the first cover plate 120 or the second cover plate 130 can also be detachably connected to the carrier plate 110 by means of snap connection, screw connection, etc. This application does not limit the specific connection method between the first cover plate 120, the second cover plate 130 and the carrier plate 110.

[0047] Traditionally, when a product is placed in a mold cavity for testing, the outer contour of the product is positioned by the mold cavity. If the mold cavity is a contour cavity, the mold cavity positioning requires too high an accuracy for the outer contour of the product. Figure 1-Figure 3 As shown, the inspection fixture 100 further includes a first positioning module 150 and a second positioning module 160. The first positioning module 150 is configured to accurately position the first product 200 accommodated in the mold cavity 111, and the second positioning module 160 is configured to accurately position the second product 300 accommodated in the mold cavity 111. By positioning the first product 200 and the second product 300 respectively by the first positioning module 150 and the second positioning module 160, the positional accuracy of the first product 200 and the second product 300 during the inspection process can be ensured.

[0048] Specifically, see Figure 1-Figure 3 As shown, the first positioning module 150 includes a plurality of first positioning posts 151, which are all disposed on the carrier 110. The plurality of first positioning posts 151 are spaced apart along the periphery of the cavity 111, and at least two first positioning posts 151 are located on opposite sides of the cavity 111. For example, see Figure 3As shown, the first positioning module 150 includes two first positioning posts 151, one of which is located on one side of the cavity 111, and the other is located on the other side of the cavity 111, that is, the two first positioning posts 151 are located at two relatively distant positions within the cavity 111. When testing the first product 200, the first product 200 is placed in the cavity 111, and the circumferential dimension of the cavity 111 is greater than or equal to the outer contour dimension of the first product 200. The first product 200 is roughly positioned by the cavity 111, and the outer contour or characteristic holes of the first product 200 are precisely positioned by multiple first positioning posts 151. The first positioning posts 151 can reduce the constraints on the positioning process of the first product 200, avoiding the undesirable phenomenon of jamming due to over-limiting during the positioning process of the first product 200.

[0049] Similarly, the second positioning module 160 includes a plurality of second positioning posts 161, which are all disposed on the carrier 110. The plurality of second positioning posts 161 are spaced apart along the periphery of the cavity 111, with at least two second positioning posts 161 being located on opposite sides of the cavity 111. For example, see Figure 3 As shown, the second positioning module 160 includes two second positioning posts 161, one of which is located on one side of the cavity 111, and the other is located on the other side of the cavity 111, that is, the two second positioning posts 161 are located at two relatively distant positions within the cavity 111. When testing the second product 300, the second product 300 is placed in the cavity 111, and the circumferential dimension of the cavity 111 is greater than or equal to the outer contour dimension of the second product 300. The second product 300 is roughly positioned by the cavity 111, and the outer contour or characteristic hole of the second product 300 is precisely positioned by multiple second positioning posts 161. The second positioning posts 161 can reduce the constraints on the positioning process of the second product 300, avoiding the undesirable phenomenon of jamming due to over-limiting during the positioning process of the second product 300.

[0050] In order to protect the appearance of the first product 200 and the second product 300 during the inspection process, in one embodiment, refer to Figure 1 and Figure 2As shown, the first cover plate 120 is connected to a first cushioning member 121. When the first cover plate 120 is connected to the carrier plate 110, the first cushioning member 121 is located on the side closest to the mold cavity 111. Exemplarily, the first cushioning member 121 is a cushioning foam. During the process of pressing and securing the first product 200 with the first cover plate 120, the first cushioning member 121 is located between the first product 200 and the first cover plate 120. Due to its flexibility, the first cushioning member 121 deforms upon contact with the first product 200 to adapt to the first product 200, preventing direct contact between the first cover plate 120 and the first product 200 from affecting its appearance. Similarly, the second cover plate 130 is connected to a second cushioning member 131. When the second cover plate 130 is connected to the carrier plate 110, the second cushioning member 131 is located on the side closest to the mold cavity 111. Exemplarily, the second buffer component 131 is a buffer foam. During the process of pressing and fixing the second product 300 by the second cover plate 130, the second buffer component 131 is located between the second product 300 and the second cover plate 130. Since the second buffer component 131 is flexible, when the second buffer component 131 contacts the second product 300, it can be deformed to adaptively fit the second product 300, thereby avoiding direct contact between the second cover plate 130 and the second product 300 and affecting the appearance of the first product 200.

[0051] In one embodiment, see Figure 1 and Figure 2 As shown, both the first product 200 and the second product 300 have a conductive portion 400. For example, both the first product 200 and the second product 300 include a flexible circuit board, and the flexible circuit board has a conductive portion 400. Figure 6 As shown, the detection assembly 140 includes a fixing base 141, a flip plate 142, a signal adapter 143 and a probe module 144. The signal adapter 143 and the probe module 144 are both arranged on the flip plate 142, and the fixing base 141 is arranged on the carrier 110 to achieve the installation and fixation of the detection assembly 140. The flip plate 142 is rotatably arranged on the fixing base 141, and during the rotation of the flip plate 142, the probe module 144 has a first state of abutting the conductive part 400 and a second state of being separated from the conductive part 400. The signal adapter 143 is arranged on the flip plate 142, and the signal adapter 143 is communicatively connected to the probe module 144, such as the signal adapter 143 is communicatively connected to the probe module 144 through a cable, Bluetooth, WIFI, etc., and a protective plate 149 is provided on the outer cover of the signal adapter 143 to ensure the stability of the working environment of the signal adapter 143 and to protect the signal adapter 143. For example, see Figure 1 and Figure 4As shown, when the first product 200 needs to be inspected, the first product 200 is placed in the mold cavity 111, and the flip plate 142 rotates to the first state of contacting the conductive portion 400 of the first product 200. The signal adapter 143 transmits the detection signal of the first product 200 to the outside world. After the inspection of the first product 200 is completed, the flip plate 142 rotates to the second state of separation from the conductive portion 400 of the second product 300, so as to facilitate the replacement operation of the first product 200. Similarly, refer to Figure 2 and Figure 5 As shown, when the second product 300 needs to be inspected, the second product 300 is placed in the mold cavity 111, and the flip plate 142 is rotated to the first state of abutting the conductive part 400 of the second product 300, and the signal adapter 143 transmits the detection signal of the second product 300 to the outside world. After the inspection of the second product 300 is completed, the flip plate 142 is rotated to the second state of being separated from the conductive part 400 of the second product 300, so as to facilitate the replacement operation of the second product 300.

[0052] Specifically, see Figure 1-Figure 3 and Figure 6 As shown, the detection assembly 140 further includes a positioning block 145, which is disposed on the fixing seat 141 and has a positioning groove 1451. When the first product 200 or the second product 300 is accommodated in the mold cavity 111, the conductive portion 400 is located in the positioning groove 1451. The positioning groove 1451 limits the conductive portion 400 to ensure the position accuracy of the conductive portion 400, improve the contact position accuracy between the probe module 144 and the conductive portion 400, and further improve the reliability of electrical testing of the first product 200 and the second product 300. Since the conductive part 400 is located on the flexible circuit board, when the first product 200 or the second product 300 is accommodated in the mold cavity 111, the conductive part 400 is adsorbed on the positioning block 145. If a connector 1452 is provided on the positioning block 145, the gas in the positioning groove 1451 can be extracted through the connector 1452 to adsorb the conductive part 400 through the vacuum negative pressure, thereby ensuring the flatness of the conductive part 400 in the positioning groove 1451 and avoiding the electrical crimping of the first product 200 or the second product 300 due to the warping of the conductive part 400.

[0053] Further, see Figure 1-Figure 3 and Figure 6As shown, the detection assembly 140 further includes a floating plate 146. The floating plate 146 is floatingly disposed on the flip plate 142, for example, by being mounted on the flip plate 142 via equal-height bolts 1461. The probe module 144 is fixed to the floating plate 146. Due to the floating of the floating plate 146 relative to the flip plate 142, when the probe module 144 abuts the conductive portion 400, on the one hand, the probe module 144 can fine-tune the abutment position of the adaptive conductive portion 400 in three-dimensional space, further ensuring the abutment position accuracy between the probe module 144 and the conductive portion 400, thereby further improving the reliability of electrical testing of the first product 200 and the second product 300. On the other hand, when the probe module 144 abuts the conductive portion 400, the instantaneous force between the probe module 144 and the conductive portion 400 is buffered, thereby protecting the probe module 144.

[0054] In one embodiment, see Figure 1-Figure 3 and Figure 6 As shown, the detection assembly 140 further includes at least one hook 147, and the hook 147 is rotatably disposed on the carrier 110. Figure 4 and Figure 5 As shown, when the probe module 144 is in the first state, the hook 147 is hooked on the flip plate 142, locking the flip plate 142 in the first state where the probe module 144 abuts against the conductive portion 400, and performing electrical testing on the first product 200 or the second product 300; Figure 1 and Figure 2 As shown, when the probe module 144 is in the second state, the hook 147 is separated from the flip plate 142, so that the flip plate 142 can be rotated to the second state where the probe module 144 is separated from the conductive portion 400, thereby facilitating the replacement operation of the first product 200 and the second product 300. Figure 6 As shown, the flip plate 142 is rotatably set on the fixed seat 141 through the rotating shaft 148, and a plurality of torsion springs 1481 are set on the rotating shaft 148. When external force is applied to the flip plate 142, the flip plate 142 overcomes the elastic force of the torsion spring 1481, so that the flip plate 142 switches from the second state to the first state to perform electrical detection of the first product 200 or the second product 300; on the contrary, when the external force acting on the flip plate 142 is removed and the hook 147 rotates and separates from the flip plate 142, under the elastic force of the torsion spring 1481, the flip plate 142 is reset from the first state to the second state, thereby facilitating the replacement operation of the first product 200 or the second product 300.

[0055] Also, see Figure 1-Figure 3As shown, the present application also provides a testing device, which includes a machine and a testing fixture 100 such as the above-mentioned technical solution. The testing device is used to perform electrical testing on a first product 200 and a second product 300. The testing fixture 100 is loaded on the machine to load the first product 200 or the second product 300 carried thereon into the testing device for electrical testing. When testing the first product 200 and the second product 300, the above-mentioned testing device can place the first product 200 or the second product 300 in the mold cavity 111, ensuring consistency in the testing environment of the first product 200 and the second product 300, thereby improving the reliability of the test results of the first product 200 and the second product 300.

[0056] 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.

[0057] 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.
