Abstract
Description
Technical Field
[0001] This application relates to the field of product testing technology, and in particular to a testing organization. Background Technology
[0002] Display modules, as crucial components for human-computer interaction, are widely used in electronic devices. Before leaving the factory, display modules undergo performance testing. Typically, this is done by placing the display module in a testing device and using the device's crimping and conductive modules to establish electrical connection between the display module and an external testing device, thus performing electrical testing on the display module.
[0003] Generally, after the display module is placed on the carrier, its B2B (board to board) connector is plugged into the back of the PCB (Printed Circuit Board) to achieve electrical connection between the display module and the test module. However, the operating space during the insertion process is too small, and after the display module is tested, the carrier along with the display module must be disassembled and rotated 180° before the display module can be disassembled. The insertion and removal of the display module is too cumbersome and seriously affects the disassembly efficiency. Utility Model Content
[0004] Therefore, it is necessary to provide a testing mechanism to address the problem of overly cumbersome plugging and unplugging operations in the existing display module testing process.
[0005] A testing organization, the testing organization comprising:
[0006] A carrier for carrying the product under test, the product under test having a test end;
[0007] A test piece connected to the carrier, the test piece having an electrical connection terminal;
[0008] The disengagement assembly includes a main body and a conductive member. The main body is disposed on the carrier and is movable between a first position and a second position. The conductive member has a first conductive end and a second conductive end. The first conductive end is electrically connected to the electrical connection end, and the second conductive end is fixed to the main body.
[0009] Specifically, when the product under test is placed on the carrier and the main body moves to the first position, the second conductive terminal is electrically connected to the product under test; when the main body moves to the second position, the second conductive terminal is separated from the product under test.
[0010] In one embodiment, the disengagement component further includes a drive module for driving the body to move between the first position and the second position.
[0011] In one embodiment, the drive module includes a connecting block and a rolling element. The connecting block is embedded in the body, and the body is movable relative to the connecting block between a first position and a second position. The connecting block has an inclined surface and is fixed to the carrier and / or the test piece. The rolling element is embedded in the body and cooperates with the inclined surface.
[0012] When the rolling element rolls on the inclined plane, it drives the main body to move between the first position and the second position.
[0013] In one embodiment, the drive module further includes a pressing member connected to the rolling member and extending at least partially outward from the body.
[0014] In one embodiment, the body is provided with a guide hole that extends between the first position and the second position;
[0015] The drive module also includes a guide member, which is movably inserted into the guide hole and connected to the connecting block. The guide member extends at least partially to the outside of the main body and is located on opposite sides of the main body to the pressing member.
[0016] In one embodiment, the main body can move between a third position and a fourth position relative to the carrier. When the main body moves to the third position, the main body avoids the position where the end to be tested needs to be placed. When the main body moves to the fourth position, the second conductive end is directly facing the position where the end to be tested needs to be placed.
[0017] In one embodiment, the main body is provided with a first magnetic attractor, and the carrier or the test piece is provided with a plurality of second magnetic attractors that can cooperate with the first magnetic attractor, the plurality of second magnetic attractors being distributed at intervals between the third position and the fourth position.
[0018] In one embodiment, the body is provided with at least one elastic element located between the body and the carrier, and the elastic element deforms between the first position and the second position.
[0019] In one embodiment, the main body includes a housing and a cover plate, the cover plate being detachably disposed on the housing, and the second conductive end being fixed to the housing.
[0020] In one embodiment, the carrier has a bearing cavity for holding the product under test;
[0021] The test piece has a placement slot, and when the product to be tested is placed in the bearing cavity, the end to be tested is placed in the placement slot.
[0022] In the aforementioned testing mechanism, when the product under test (DUT) is placed on the carrier and the main body moves to the first position, the second conductive terminal is electrically connected to the DUT, achieving electrical conductivity between the test piece and the DUT, allowing for electrical testing of the DUT. After the DUT is tested, the main body moves to the second position, causing the second conductive terminal to separate from the DUT, facilitating the removal and removal of the DUT. The testing mechanism provided in this application achieves electrical connection between the test piece and the DUT through a conductive adapter, unaffected by the position of the electrical connection terminal on the test piece. The electrical connection operation between the test piece and the DUT is simple, and after the DUT is tested, the main body moves to separate the conductive adapter from the DUT, allowing operators to remove and remove the DUT after testing, simplifying the insertion and removal operations of the DUT.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. 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.
[0039] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.
[0040] See Figures 1-3 As shown, this application provides a testing mechanism 100, which includes a carrier 110, a test piece 120, and a disconnection assembly 130. The carrier 110 is used to carry a product under test (DUT) 200, which has a test terminal 210. The test piece 120 is connected to the carrier 110 and has an electrical connection terminal (not shown). Exemplarily, the test piece 120 is a PCB (Printed Circuit Board). The testing mechanism 100 can perform electrical tests on the DUT 200, which can be a display module for mobile phones, computers, tablets, etc.
[0041] The disconnect assembly 130 includes a main body 131 and a conductive member 132. The main body 131 is disposed on a carrier 110 and is movable between a first position and a second position. The main body 131 can be directly disposed on the carrier 110, or it can be disposed on a test piece 120 to indirectly dispose of it on the carrier 110. The conductive member 132 has a first conductive end 1321 and a second conductive end 1322. Exemplarily, the conductive member 132 is an FPC (Flexible Printed Circuit). The first conductive end 1321 is located at one end of the conductive member 132, and the second conductive end 1322 is located at the other end. The first conductive end 1321 is electrically connected to an electrical connection end, and the second conductive end 1322 is fixed to the main body 131.
[0042] When the product under test 200 is placed on the carrier 110 and the main body 131 moves to the first position, the second conductive terminal 1322 is electrically connected to the end under test 210. Since the first conductive terminal 1321 is electrically connected to the electrical connection terminal, electrical conduction between the test piece 120 and the product under test 200 is achieved through the conductive component 132, allowing electrical testing of the product under test 200. When the main body 131 moves to the second position, the second conductive terminal 1322 separates from the end under test 210. For example, after the product under test 200 is tested, the main body 131 moves to the second position and causes the second conductive terminal 1322 to separate from the end under test 210, facilitating the removal and removal of the product under test 200.
[0043] The aforementioned testing mechanism 100 achieves electrical connection between the test piece 120 and the product under test 200 through the conductive element 132. This connection is unaffected by the position of the electrical connection terminal on the test piece 120. In particular, when the electrical connection terminal is located on the back of the test piece 120, the conductive element 132 can transfer the electrical connection terminal to a position that facilitates insertion of the product under test 200. The electrical connection operation between the test piece 120 and the product under test 200 is simple. After the product under test 200 is tested, the main body 131 drives the conductive element 132 to separate from the product under test 200. The operator can then remove and re-remove the product under test 200 after testing, simplifying the insertion and removal operation of the product under test 200.
[0044] In one embodiment, see Figures 1-3As shown, the disconnection assembly 130 also includes a drive module 133, which drives the main body 131 to move between a first position and a second position. For example, when the drive module 133 drives the main body 131 to the first position, the second conductive end 1322 is electrically connected to the end under test 210, achieving electrical connection between the test piece 120 and the product under test 200 through the conductive element 132, allowing for electrical testing of the product under test 200. Alternatively, when the drive module 133 drives the main body 131 to the second position, the second conductive end 1322 is separated from the end under test 210, and the conductive element 132 will not interfere with the removal / removal operation of the product under test 200, facilitating the removal / removal operation of the product under test 200.
[0045] Specifically, see Figures 1-4 As shown, the drive module 133 includes a connecting block 1331 and a rolling element 1332. The connecting block 1331 is embedded in the main body 131. If the main body 131 has a shell structure, it has a cavity for accommodating the connecting block 1331, and the main body 131 can move between a first position and a second position relative to the connecting block 1331. The connecting block 1331 has an inclined surface 1333 and is fixed to the carrier 110 and / or the test piece 120. The rolling element 1332 is embedded in the main body 131 and engages with the inclined surface 1333. When the rolling element 1332 rolls on the inclined surface 1333, it drives the main body 131 to move between the first position and the second position.
[0046] For example, when the rolling element 1332 rolls on the inclined plane 1333, the connecting block 1331 cannot move because it is fixed to the carrier 110 and / or the test piece 120. At this time, the rolling element 1332 can drive the main body 131 to move between the first position and the second position during the rolling process. Specifically, if the rolling element 1332 drives the main body 131 to the first position, electrical connection can be achieved between the test piece 120 and the product under test 200; if the rolling element 1332 drives the main body 131 to the second position, the second conductive end 1322 can be separated from the end under test 210, and the conductive element 132 will not interfere with the removal and removal operation of the product under test 200, which facilitates the removal and removal operation of the product under test 200.
[0047] Further, see Figure 2 and Figure 4As shown, the drive module 133 also includes a pressing member 1334, which is connected to the rolling member 1332. An operator can press, push, or squeeze the pressing member 1334 to transmit external force to the rolling member 1332, thereby driving the rolling member 1332 to roll on the inclined plane 1333, thus moving the main body 131 between the first and second positions. Furthermore, the pressing member 1334 extends at least partially beyond the outer side of the main body 131, facilitating pressing operations on the rolling member 1332. Preferably, the surface of the pressing member 1334 extending beyond the main body 131 has an anti-slip layer to increase the friction between the pressing member 1334 and the operator's operating part, further improving the ease and reliability of operation of the rolling member 1332.
[0048] Furthermore, see Figure 2 and Figure 4 As shown, the main body 131 is provided with a guide hole 1311. Preferably, the guide hole 1311 is integrally formed into the main body 131 by injection molding, extrusion, or other methods to simplify the molding process of opening the guide hole 1311 in the main body 131. The guide hole 1311 extends between the first position and the second position. For example, the guide hole 1311 is an elongated hole, and the extension direction of the guide hole 1311 is the movement direction of the main body 131 between the first position and the second position. The drive module 133 also includes a guide member 1335, which is movably inserted into the guide hole 1311. For example, the guide member 1335 is inserted into the guide hole 1311, and there is a gap between the guide member 1335 and the guide hole 1311 to avoid the guide member 1335 interfering with the movement of the main body 131. The guide member 1335 is connected to the connecting block 1331. The guide member 1335 extends at least partially to the outside of the main body 131, and the guide member 1335 and the pressing member 1334 are located on opposite sides of the main body 131, facilitating the operator to perform movement operations on the main body 131 between the first position and the second position. Specifically, when performing movement operations on the main body 131, the operator can hold, touch, or otherwise act on the pressing member 1334 and the guide member 1335, and apply external force to the pressing member 1334 to drive the rolling member 1332 to roll on the inclined plane 1333, thereby moving the main body 131 between the first position and the second position.
[0049] The aforementioned testing mechanism 100, through the movement of the guide member 1335 within the guide hole 1311, can guide the movement of the main body 131 between the first position and the second position. The guide member 1335 and the pressing member 1334 provide the operator's operating position, making it convenient for the operator to perform the movement operation of the main body 131 between the first position and the second position, and the guide member 1335 will not interfere with the movement of the main body 131.
[0050] In one embodiment, see Figures 1-3 As shown, the main body 131 can move between a third position and a fourth position relative to the carrier 110. When the main body 131 moves to the third position, the main body 131 avoids the position where the test end 210 needs to be placed. When the main body 131 moves to the fourth position, the second conductive end 1322 is directly facing the position where the test end 210 needs to be placed. For example, during the testing of the product under test 200, firstly, the main body 131 moves to the third position, avoiding the position where the test terminal 210 needs to be placed. The main body 131 will not interfere with the insertion action of the test terminal 210. At this time, the test terminal 210 of the product under test 200 can be placed on the carrier 110 or the test piece 120. Then, after the test terminal 210 of the product under test 200 is placed in the test position, the main body 131 moves to the fourth position, with the second conductive terminal 1322 facing the position where the test terminal 210 needs to be placed. Finally, the main body 131 moves to the first position, causing the second conductive terminal 1322 to contact and electrically connect with the test terminal 210, realizing electrical conduction between the product under test 200 and the test piece 120, enabling electrical testing of the product under test 200.
[0051] Specifically, see Figures 1-3 As shown, the main body 131 is provided with a first magnetic suction member 1312, and the carrier 110 or test piece 120 is provided with a plurality of second magnetic suction members 140. The second magnetic suction members 140 can cooperate with the first magnetic suction member 1312, and the plurality of second magnetic suction members 140 are distributed at intervals between the third position and the fourth position. For example, if there are two sets of second magnetic suction members 140, and the two sets of second magnetic suction members 140 are respectively set in the third position and the fourth position, when the first magnetic suction member 1312 cooperates with the second magnetic suction member 140 in the third position, the main body 131 can be maintained in the third position for insertion and placement of the product under test 200; when the first magnetic suction member 1312 cooperates with the second magnetic suction member 140 in the fourth position, the main body 131 can be maintained in the fourth position for electrical conduction between the product under test 200 and the test piece 120; or, for example, the second magnetic suction member 140 is provided with a first magnetic suction member 1312, and the test piece 120 is provided with a plurality of second magnetic suction members 140. The magnetic suction element 140 consists of three sets, which are spaced apart between the third and fourth positions. When the first magnetic suction element 1312 engages with two sets of second magnetic suction elements 140 near the third position, the main body 131 can be held in the third position for insertion and placement of the product under test 200. When the first magnetic suction element 1312 engages with the other two sets of second magnetic suction elements 140 near the fourth position, the main body 131 can be held in the fourth position for electrical connection between the product under test 200 and the test piece 120. Of course, in other feasible embodiments, the number of second magnetic suction elements 140 can be four, five, or other. This application does not limit the specific number of second magnetic suction elements 140.
[0052] The first magnetic attractor 1312 can be a magnet formed from atoms such as iron, cobalt, and nickel, and the second magnetic attractor 140 can also be a magnet formed from atoms such as iron, cobalt, and nickel. Alternatively, one of the first magnetic attractor 1312 and the second magnetic attractor 140 can be a magnet formed from atoms such as iron, cobalt, and nickel, and the other of the first magnetic attractor 1312 and the second magnetic attractor 140 can be a magnetic metal block.
[0053] The aforementioned testing mechanism 100, through the magnetic attraction between the first magnetic member 1312 and the second magnetic member 140, can maintain the main body 131 in the third position for inserting and placing the product under test 200, or maintain the main body 131 in the fourth position for electrical conduction between the product under test 200 and the test piece 120.
[0054] In one embodiment, see Figures 1-3 As shown, the main body 131 is provided with at least one elastic element 1313, which is located between the main body 131 and the carrier 110, and the elastic element 1313 deforms between a first position and a second position. Thus, when an external force is applied to the main body 131, the main body 131 moves between the first position and the second position, and the main body 131 can drive the elastic element 1313 to undergo elastic deformation. After the external force applied to the main body 131 is removed, the elastic element 1313 elastically resets, realizing the reset operation of the main body 131.
[0055] Preferably, there are multiple elastic elements 1313, and the multiple elastic elements 1313 are spaced apart, which can ensure sufficient elastic restoring force and improve the stability of the main body during movement. For example, the elastic element 1313 is a return spring, and the restoring operation of the main body 131 is achieved through the elastic deformation of the elastic element 1313. Of course, in other feasible embodiments, the elastic element 1313 can also be an elastic sheet or other elastic element. This application does not limit the specific element type of the elastic element 1313.
[0056] In one embodiment, see Figures 1-4 As shown, the main body 131 includes a housing 1314 and a cover plate 1315. The cover plate 1315 is detachably disposed on the housing 1314, such as by screwing, snapping, riveting, or other means. Thus, by removing the cover plate 1315, components inside the housing 1314 (such as the drive module structure) can be reset or replaced. The second conductive terminal 1322 is fixed to the housing 1314. When the housing 1314 moves between the first position and the second position, the housing 1314 can drive the second conductive terminal 1322 to be electrically connected to the test terminal 210 for electrical continuity testing of the test product 200, or drive the second conductive terminal 1322 to be separated from the test terminal 210 for easy removal and removal of the test product 200.
[0057] In one embodiment, see Figures 1-4 As shown, the carrier 110 has a bearing cavity 111 for holding the product under test 200. Preferably, the bearing cavity 111 is integrally formed into the carrier 110 by injection molding, extrusion, or other methods, simplifying the molding process of opening the bearing cavity 111 in the carrier 110. Furthermore, the bearing cavity 111 is preferably a contoured cavity, improving the ease and stability of placing the product under test 200. The test piece 120 has a placement groove 121. When the product under test 200 is placed in the bearing cavity 111, the end to be tested 210 is accommodated in the placement groove 121. Preferably, the placement groove 121 is integrally formed into the test piece 120 by injection molding, extrusion, or other methods, improving the ease and stability of placing the end to be tested 210.
[0058] The following combination Figures 1-6 The testing procedures performed by the testing organization 100 provided in this application on the product 200 to be tested are described in detail.
[0059] First, the main body 131 moves to the third position, avoiding the placement groove 121; then, the product under test 200 is placed in the bearing cavity 111, and the end under test 210 is accommodated in the placement groove 121; next, the main body 131 moves to the fourth position, so that the second conductive end 1322 faces the end under test 210; then, the main body 131 moves to the first position, and the second conductive end 1322 is electrically connected to the electrical connection end to achieve electrical conduction between the product under test 200 and the test piece 120, and an electrical test is performed on the product under test 200; continuing, the pressing member 1334 is pressed, pushing the rolling member 1332 towards Figure 6 As shown, the movement in direction B is restricted because the connecting block 1331 is fixed to the carrier 110 and cannot move. The rolling element 1332 drives the main body 131 along... Figure 6 As shown in the C direction, the second conductive terminal 1322 separates from the terminal under test 210; finally, the operator performs the removal and removal operation of the product under test 200 to disassemble the product under test 200 after testing.
[0060] 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.
[0061] 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.
