Description

Technical Field

[0001] This invention belongs to the field of display panel testing, and more specifically, relates to a multi-screen crimping fixture, testing equipment, and testing method for automotive screens. Background Technology

[0002] With the increasing development of new energy vehicles, in-vehicle screens are being used more and more in the field of automotive displays, and are developing towards larger screens, higher definition, interactivity, multiple screens, and multiple forms. The functions of in-vehicle screens are also increasing.

[0003] In related technologies, multi-screen modules include multiple internal vehicle-mounted screens and external plastic components. The multiple vehicle-mounted screens are spaced apart and inserted into the plastic components, and the connectors of each vehicle-mounted screen extend from the back of the plastic components. After the multi-screen module is assembled, the plastic components are installed inside the vehicle, thus achieving the integrated installation of multiple vehicle-mounted screens simultaneously.

[0004] However, during vehicle factory testing, most of the in-vehicle screens in the assembled multi-screen modules can work normally or interact with each other. But a small number of the in-vehicle screens in the assembled multi-screen modules malfunction during the assembly process (cannot be lit or the display performance does not meet the requirements), which requires the assembled multi-screen modules to be disassembled for replacement or repair, thus increasing the cost of vehicle production. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a multi-screen crimping fixture, testing equipment, and testing method for automotive screens. The purpose is to enable performance testing of multiple automotive screens in advance and simultaneously before the installation of multi-screen modules, thereby avoiding the need for disassembly, replacement, or repair due to malfunctions after installation and reducing automotive production costs.

[0006] In a first aspect, embodiments of the present invention provide a multi-screen crimping fixture for vehicle-mounted screens, the multi-screen crimping fixture including a support component and a crimping component;

[0007] The support assembly includes a carrier plate and a flip plate. The flip plate has multiple first clearance areas and a first plate surface and a second plate surface arranged opposite to each other. The carrier plate has a second clearance area. The flip plate can be flipped relative to the carrier plate. Multiple positioning blocks are movably arranged on the first plate surface to position the multi-screen module on the flip plate.

[0008] The crimping assembly includes a plurality of crimping members for crimping the vehicle screen connector. The plurality of crimping members are arranged opposite to the second clearance area. The plurality of crimping members are spaced apart on the second plate surface, and each crimping member is located on one side of the corresponding first clearance area.

[0009] Optionally, the middle parts of both sides of the flip plate are rotatably arranged in the second clearance area via rotating shafts, and each rotating shaft is arranged parallel to the flip plate.

[0010] Optionally, one side of the inner wall of the second clearance area has at least one first limiting block, and the other side of the inner wall of the second clearance area has at least one second limiting block. The rotating shaft is located between the first limiting block and the second limiting block. When the first plate is arranged facing upward, one side of the flip plate overlaps the first limiting block. When the second plate is arranged facing upward, the other side of the flip plate overlaps the second limiting block.

[0011] Optionally, at least one pin is movably arranged on the carrier plate, and each of the opposite sides of the flip plate has a limiting groove, in which the pin is movably inserted.

[0012] Optionally, a hinge shaft runs through the second clearance area, and the inner wall of the second clearance area has protrusions on both sides that limit the movement of the flip plate. The hinge shaft is located between the two protrusions, and one side of the flip plate is hinged to the hinge shaft.

[0013] Optionally, the carrier plate has a hinge shaft on one side, and one side of the flip plate is hinged to the hinge shaft.

[0014] Secondly, embodiments of the present invention provide a testing device, the testing device including a multi-screen crimping fixture for vehicle-mounted screens as described in the first aspect.

[0015] Optionally, the testing equipment further includes at least one adapter PCB board and a signal generator. The adapter PCB board and the plurality of the crimping components are all electrically connected. Each adapter PCB board is located on the second board surface, and each adapter PCB board is electrically connected to the signal generator through a plug and socket connection.

[0016] Optionally, the testing equipment further includes a robotic arm, which is connected to the flip plate to flip the flip plate.

[0017] Thirdly, embodiments of the present invention provide a testing method, the testing method being based on the multi-screen crimping fixture for vehicle-mounted screens described in the first aspect, the testing method comprising:

[0018] The multi-screen module is placed on the first board surface, and the multi-screen module is positioned on the first board surface by the multiple positioning blocks;

[0019] Flip the flip plate so that the plurality of crimping parts on the second plate surface are exposed after flipping, thereby allowing the connectors of each vehicle screen to pass through the corresponding first clearance area and crimp each connector onto the corresponding crimping part;

[0020] The flip plate is reversed so that the multi-screen module is arranged facing upwards, and the vehicle screen is lit up by providing electrical signals to each of the pressing parts.

[0021] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0022] For the multi-screen crimping fixture for vehicle-mounted screens provided in this embodiment of the invention, after the multi-screen module is assembled, firstly, the multi-screen module is placed on the first plate surface of the flip plate (at this time, the first plate surface is arranged upwards), and the multi-screen module is positioned on the flip plate by multiple positioning blocks to prevent the multi-screen module from falling off during subsequent flipping. Then, the flip plate is flipped so that multiple crimping parts are exposed after flipping, and the connectors of each vehicle-mounted screen in the multi-screen module pass through the corresponding first clearance area.

[0023] Next, the connectors of each vehicle screen are crimped together using corresponding crimping devices. Electrical signals are then supplied to each crimping device to illuminate each vehicle screen. Finally, the flip panel is flipped again (so that the first panel faces upwards), and the display performance of each vehicle screen is tested. This allows for performance testing of multiple vehicle screens before installation of the multi-screen module, avoiding the need for disassembly, replacement, or repair due to malfunctions after installation, thereby reducing automotive production costs.

[0024] In other words, the multi-screen crimping fixture for vehicle screens provided in this embodiment of the invention can perform performance testing on multiple vehicle screens in advance and simultaneously before the installation of the multi-screen module, avoiding the problem of disassembly, replacement or repair due to failure after the installation of the multi-screen module, thereby reducing the cost of automobile production.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0036] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this invention.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Figure 1 This is a schematic diagram of the first state of use of a multi-screen crimping fixture for vehicle-mounted screens provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the multi-screen crimping fixture includes a support component 1 and a crimping component 2.

[0041] Figure 2 This is a schematic diagram of the structure of the support component provided in an embodiment of the present invention, such as... Figure 2 As shown, the support assembly 1 includes a carrier plate 11 and a flip plate 12. The flip plate 12 has a plurality of first clearance areas 121, and the flip plate 12 has a first plate surface 122 and a second plate surface 123 arranged opposite to each other (see...). Figure 3 The carrier plate 11 has a second avoidance area 111, the flip plate 12 can be flipped relative to the carrier plate 11, and a plurality of positioning blocks 1221 are movably arranged on the first plate surface 122 to position the multi-screen module 100 on the flip plate 12.

[0042] The crimping assembly 2 includes a plurality of crimping elements 21 for crimping the connector of the vehicle screen 200 (see...). Figure 4Multiple crimping parts 21 are arranged opposite to the second clearance area 111. Multiple crimping parts 21 are arranged at intervals on the second plate surface 123, and each crimping part 21 is located on one side of the corresponding first clearance area 121.

[0043] For the multi-screen crimping fixture for a vehicle-mounted screen 200 provided in this embodiment of the invention, after the multi-screen module 100 is assembled, firstly, the multi-screen module 100 is placed on the first plate surface 122 of the flip plate 12 (at this time, the first plate surface 122 is arranged facing upwards, see...). Figure 1 The multi-screen module 100 is positioned on the flip plate 12 by multiple positioning blocks 1221 to prevent it from falling off during subsequent flipping. Then, the flip plate 12 is flipped so that multiple pressing parts 21 are exposed after flipping, and the connectors of each vehicle screen 200 in the multi-screen module 100 pass through the corresponding first clearance area 121. It should be noted that those skilled in the art will understand that the multiple first clearance areas 121 on the flip plate 12 can be set separately and independently, or they can be connected as one unit, and this application does not limit this.

[0044] Next, the connectors of each vehicle screen 200 are crimped together using the corresponding crimping pieces 21. Electrical signals are then supplied to each crimping piece 21 to illuminate each vehicle screen 200. Finally, the flip plate 12 is flipped again (so that the first plate surface 122 faces upwards), and the display performance of each vehicle screen 200 is tested. This allows for performance testing of multiple vehicle screens 200 before the multi-screen module 100 is installed, preventing the need for disassembly, replacement, or repair due to malfunctions after installation, thus reducing automotive production costs.

[0045] In other words, the multi-screen crimping fixture for vehicle screens provided in this embodiment of the invention can perform performance testing on multiple vehicle screens 200 in advance and simultaneously before the installation of the multi-screen module 100, avoiding the problem of disassembly, replacement or repair due to failure after the installation of the multi-screen module 100, thereby reducing the cost of automobile production.

[0046] It should be noted that the crimping component 21 provided by the present invention is a conventional crimping conductive structure in the art, which may specifically include a base, a flip cover, and a mold core, etc.

[0047] For example, the number of vehicle screens 200 in the multi-screen module 100 can be 1-4 (this embodiment uses 3 as an example for illustration), and the corresponding pressing parts 21 can be 1-4, etc. The present invention does not limit this.

[0048] In addition, after the performance testing of multiple vehicle screens 200 is completed, the crimping of each vehicle screen 200 connector is released. Then, multiple positioning blocks 1221 are moved to release the positioning of the multi-screen module 100. At this time, the multi-screen module 100 that has been tested is removed, and then the above steps are repeated to test the next multi-screen module 100.

[0049] In one implementation of this embodiment, the first plate 122 has a plurality of spaced slide rail groups, each slide rail group including at least one slide rail 1222, and each slide rail 1222 is slidably provided with a positioning block 1221 to press against the outer edge of the multi-screen module 100 after sliding.

[0050] In the above embodiment, the position of the positioning block 1221 can be adjusted by sliding the positioning block 1221, thereby sliding the positioning block 1221 above the multi-screen module 100, and then cooperating with the flip plate 12 to clamp the multi-screen module 100, thereby achieving the positioning of the multi-screen module 100 on the first plate surface 122 of the flip plate 12.

[0051] For example, since the multi-screen module 100 is elongated and its top is relatively flat, it can be positioned using a large positioning block 1221. The bottom of the multi-screen module 100 has an irregular structure and can be positioned using three small positioning blocks 1221.

[0052] For example, each slide rail group includes two parallel and spaced slide rails 1222, thereby ensuring the stability of the sliding of the positioning block 1221.

[0053] Furthermore, each positioning block 1221 has a first magnet (not shown in the figure), and each slide rail 122 has a second magnet 1223 on the first plate surface 122 and next to both ends of each slide rail 1222. The first magnet and any one of the opposite second magnets 1223 are matched with each other.

[0054] In the above embodiment, the magnetic force between the first magnet and the second magnet 1223 can be used to attract and position the positioning block 1221, thereby preventing the positioning block 1221 from accidentally sliding and causing it to release its fixation to the multi-screen module 100.

[0055] For example, when each positioning block 1221 causes the first magnet to slide to correspond with a second magnet 1223, the second magnet 1223 has a magnetic force on the first magnet, the positions of the first magnet and the positioning block 1221 remain fixed, and the positioning block 1221 precisely presses against the multi-screen module 100. When each positioning block 1221 causes the first magnet to slide to correspond with another second magnet 1223, the other second magnet 1223 has a magnetic force on the first magnet, the positions of the first magnet and the positioning block 1221 remain fixed, and the positioning block 1221 is misaligned with the multi-screen module 100, at which point the multi-screen module 100 can be picked up and put down.

[0056] For example, multiple limiting blocks are provided on the flip plate 12, and each limiting block is arranged at both ends of the slide rail 1222 to limit the sliding of the positioning block 1221 and ensure the sliding accuracy of the positioning block 1221.

[0057] In another implementation of the invention, the first plate surface 122 has a plurality of spaced-apart pneumatic grippers 1224 (see...). Figure 5 Each pneumatic gripper 1224 has its gripper 1225 fixedly connected to its corresponding positioning block 1221.

[0058] In the above embodiment, the pneumatic gripper 1224 can drive the gripper 1225 to rotate and rise and fall by air pressure, thereby driving the positioning block 1221 to rotate and rise and fall, thereby realizing the positioning of the multi-screen module 100.

[0059] For example, when it is necessary to position the multi-screen module 100 on the flip plate 12, the pneumatic gripper 1224 drives the gripper 1225 and the positioning block 1221 to rotate above the multi-screen module 100 and then descend, thereby clamping the multi-screen module 100. Similarly, when it is necessary to release the positioning of the multi-screen module 100 on the flip plate 12, the pneumatic gripper 1224 drives the gripper 1225 and the positioning block 1221 to rise and rotate in the opposite direction, thereby releasing the clamping of the multi-screen module 100.

[0060] In one implementation of the present invention Figure 6 This is a schematic diagram of the structure of a carrier plate provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the middle of both sides of the flip plate 12 is rotatably arranged in the second clearance area 111 via a rotating shaft 14, and each rotating shaft 14 is arranged parallel to the flip plate 12.

[0061] In the above embodiment, rotating the center of the flip plate 12 by the pivot 14 can lower the center of gravity of the flip plate 12 during the flipping process (flipping in the counterclockwise direction A), resulting in better flipping stability. Furthermore, since the center of gravity of the flip plate 12 is close to the rotation axis, the flip plate 12 is more likely to maintain a state where the first plate surface 122 faces upwards or the second plate surface 123 faces upwards. Additionally, it can reduce the space occupied above the carrier plate 11 during the flipping process, facilitating the placement of detection equipment (e.g., a camera).

[0062] For example, one end of the rotating shaft 14 is fixedly inserted into the flip plate 12, and the other end of the rotating shaft 14 is rotatably inserted into the inner wall of the second clearance area 111.

[0063] Furthermore, one side of the inner wall of the second clearance area 111 has at least one first limiting block 1111, and the other side of the inner wall of the second clearance area 111 has at least one second limiting block 1112. The rotating shaft 14 is located between the first limiting block 1111 and the second limiting block 1112. When the first plate surface 122 is arranged facing upwards, one side of the flip plate 12 overlaps the first limiting block 1111 (see...). Figure 1 When the second plate 123 is arranged facing upwards, the other side of the flip plate 12 overlaps the second limiting block 1112 (see...). Figure 4 ).

[0064] In the above embodiment, when the first plate surface 122 is arranged facing upwards, the first limiting block 1111 can limit one side of the flip plate 12, which can prevent the flip plate 12 from accidentally flipping clockwise and affecting the pressing operation. When the second plate surface 123 is arranged facing upwards, the second limiting block 1112 can limit the other side of the flip plate 12, which can also prevent the flip plate 12 from accidentally flipping counterclockwise and affecting the operation.

[0065] It is easy to understand that the distance from the rotating shaft 14 to the first limiting block 1111 is L1, the distance from the rotating shaft 14 to the second limiting block 1112 is L2, the distance from the rotating shaft 14 to the right side of the flip plate 12 is L3, and the distance from the rotating shaft 14 to the left side of the flip plate 12 is L4 (see...). Figure 3 Among them, L3>L1, L2>L4, and L3>L2, L1>L4, so that when the flip plate 12 flips (switches from the first plate surface 122 to the second plate surface 123), the second limiting block 1112 will not affect the flip plate 12 flipping, and after the flipping is completed, the flip plate 12 just overlaps with the second limiting block 1112.

[0066] In addition, at least one pin 112 is movably arranged on the carrier plate 11, and each of the opposite sides of the flip plate 12 has a limiting groove 124, in which the pin 112 is movably inserted.

[0067] In the above embodiment, when the pin 112 is inserted into the limiting groove 124, the flip plate 12 can also be flipped and limited by the pin 112. When the pin 112 is removed from the limiting groove 124, the limiting of the flip plate 12 can be released.

[0068] For example, the pin 112 can be inserted into the limiting groove 124 by sliding or rotating.

[0069] In this embodiment, the pin 112 and the second limiting block 1112 are located on the same side of the second clearance area 111. When the first plate surface 122 is arranged facing upwards, one side of the flip plate 12 overlaps with the first limiting block 1111. At this time, the pin 112 extends into the limiting groove 124 on the bottom surface of the other side of the flip plate 12, thereby achieving the limitation of both sides of the flip plate 12 (see...). Figure 1 This simultaneously prevents the flip plate 12 from flipping clockwise and counterclockwise (by the engagement of the first limiting block 1111 and the pin 112). When the second plate surface 123 is arranged facing upwards, the other side of the flip plate 12 overlaps with the second limiting block 1112, at which time the pin 112 extends into the limiting groove 124 on the top surface of the other side of the flip plate 12 (see...). Figure 4 This allows for clamping and limiting of the other side of the flip plate 12, thereby preventing the flip plate 12 from flipping clockwise and counterclockwise at the same time.

[0070] Figure 7 This is a schematic diagram of another carrier plate provided in an embodiment of the present invention, as shown below. Figure 7 As shown, a hinge shaft 1113 passes through the second clearance area 111. The inner walls of the second clearance area 111 have protrusions 1114 on both sides that limit the movement of the flip plate 12. The hinge shaft 1113 is located between the two protrusions 1114. One side of the flip plate 12 is hinged to the hinge shaft 1113.

[0071] In the above embodiment, by cooperating with the hinge shaft 1113 and any boss 1114, support can be provided for both sides of the flip plate 12, thereby preventing the flip plate 12 from flipping.

[0072] For example, the hinge shaft 1113 divides the second clearance area 111 into a first through hole and a second through hole. When the flip plate 12 is located in the first through hole, the first plate surface 122 of the flip plate 12 faces upward. When the flip plate 12 is located in the second through hole, the second plate surface 123 of the flip plate 12 faces upward.

[0073] In another implementation of the present invention, the carrier plate 11 has a hinge shaft on one side, and the flip plate 12 is hinged to the hinge shaft on one side.

[0074] In the above embodiment, before the flip plate 12 is flipped, the flip plate 12 is placed on the carrier plate 11. After the flip plate 12 is flipped at a certain angle, the flip plate 12 can be opened so that the crimping member 21 is detached from the second clearance area 111 and exposed. At this time, the connectors of each vehicle screen 200 can be conveniently crimped by the corresponding crimping member 21.

[0075] For example, the flip angle of the flip plate 12 can be 0-180° (so that the flip plate 12 can be upright or tilted), preferably 90-180°, to facilitate the crimping of the connector.

[0076] It should be noted that in other embodiments of the present invention, the flip plate 12 can also be manually flipped, in which case no rotating shaft or hinge shaft is required, and the flip plate 12 is placed on the carrier plate 11 before and after flipping, with the first plate surface 122 facing upward.

[0077] In an embodiment of the present invention, the support assembly 1 further includes columns 13 and a base plate 15. The top ends of a plurality of columns 13 are inserted into the carrier plate 11 at intervals. The base plate 15 is arranged parallel to and at intervals with the carrier plate 11. The bottom end of each column 13 is inserted into the base plate 15.

[0078] It is easy to understand that since multiple columns 13 are arranged at the bottom of the carrier plate 11, the carrier plate 11 is raised from the work station, and the work station will not interfere with the positioning block 1221 or the pressing part 21 on the bottom surface of the flip plate 12 before and after flipping in the second clearance area 111.

[0079] In addition, the base plate 15 can not only increase the structural strength of the entire support assembly 1, but also increase the flatness of its bottom.

[0080] For example, the base plate 15 has a plurality of spaced weight-reducing holes 151, thereby reducing the mass of the entire support assembly 1.

[0081] This invention provides a testing device, which includes a multi-screen crimping fixture for vehicle-mounted screens as described above.

[0082] Specifically, the test equipment also includes at least one adapter PCB board 3 and a signal generator (not shown). The adapter PCB board 3 and multiple crimping parts 21 are all connected. Each adapter PCB board 3 is located on the second board surface 123. Each adapter PCB board 3 is connected to the signal generator through a plug and socket.

[0083] In the above embodiment, the adapter PCB board 3 acts as a connector for multiple crimping components, facilitating communication with the signal generator. That is, the electrical signal generated by the signal generator passes through the adapter PCB board and the crimping components 21, ultimately illuminating the vehicle screen. It should be noted that the adapter PCB board 3 can be configured to correspond one-to-one with multiple crimping components, enabling the vehicle screen to connect to the signal generator via the crimping components. In other implementations, the number of adapter PCB boards 3 can be one, two, or more, as long as multiple vehicle screens of a multi-screen module can be connected to the signal generator via crimping components. This application does not specifically limit this.

[0084] It is easy to understand that the adapter PCB board 3 and the signal generator are connected through a plug and socket. Therefore, during the flipping process, the adapter PCB board 3 and the signal generator are not connected. They are only connected through the plug and socket when the vehicle screen is being tested.

[0085] For example, the testing equipment may also include an imaging mechanism or an evaluation mechanism, which is not limited by the present invention.

[0086] In this embodiment, the testing equipment also includes a robotic arm, which is connected to the flip plate 12 via a transmission to flip the flip plate.

[0087] In the above embodiment, the robotic arm can drive the flip plate 12 through a suction cup or gripper, thereby causing the flip plate 12 to flip so as to crimp the connector of the vehicle screen.

[0088] For example, the flipping angle of the robotic arm flipping plate 12 can also be 0-180°, preferably 90-180°, to facilitate the crimping of the connector.

[0089] For example, the carrier plate 11 has a positioning groove, and the flip plate 12 is movably inserted into the positioning groove before and after flipping.

[0090] Figure 8 This is a flowchart of a testing method provided in an embodiment of the present invention, such as... Figure 8 As shown, this test method is based on the aforementioned multi-screen crimping fixture for automotive screens, and the test method includes:
