Technical Field
[0001] The present invention relates to the technical field of vehicle-mounted touch screen testing, and in particular to a vehicle-mounted touch screen production testing device. Background Art
[0002] As a human-computer interaction device, the car touch screen is covered on the surface of the car display screen. When the user touches the display screen, the touch screen can identify the touch point position and transmit the signal to the computer, thereby realizing the interaction between the user and the computer.
[0003] During the production process of existing in-vehicle touch screens, quality inspection tests are required for the in-vehicle touch screens. However, it is inconvenient for workers to place and take the in-vehicle touch screens, which reduces work efficiency and affects people's use. Summary of the Invention
[0004] The present application discloses a vehicle-mounted touch screen production and testing device to solve the problem in the prior art that it is inconvenient for workers to place and take the vehicle-mounted touch screen.
[0005] In order to solve the above problems, the present invention adopts the following technical solutions: A vehicle-mounted touch screen production and testing device, comprising: A test box, wherein an opening is formed on one side of the test box; A cover plate is slidably connected to the test box and is used to open or close the opening; A placement table is used to place the vehicle-mounted touch screen, and the placement table can be moved into or out of the test box through the opening; A linkage mechanism, one end of which is located within the test chamber, and the other end of which is connected to the cover. When the placement platform moves into the test chamber and continues to move, the placement platform drives the cover downward through the linkage mechanism to close the opening. When the placement platform is within the test chamber and moves toward the opening, the placement platform drives the cover upward through the linkage mechanism to open the opening. The connecting mechanism is arranged on the placement table. When the placement table moves into the test box and continues to move, the placement table is connected to the linkage mechanism through the connecting mechanism. When the placement table is located in the test box and moves toward the opening, the connecting mechanism is disconnected from the linkage mechanism so that the placement table can be moved out of the test box.
[0006] The technical solution adopted by the present invention can achieve the following beneficial effects: The present invention places the vehicle-mounted touch screen on a placement table, and then moves the placement table into the test box through the opening. During the process of continuing to move after the placement table moves into the test box, the placement table is connected and locked with the linkage mechanism through the connecting mechanism, and the linkage mechanism drives the cover plate to move downward to close the opening, so as to prevent external light from affecting the test process. After the test is completed, when the placement table is in the test box and moves toward the opening, the placement table first drives the linkage mechanism to move together through the connecting mechanism, and drives the cover plate to move upward through the linkage mechanism to open the opening. Then the connecting mechanism is disconnected from the linkage mechanism and unlocked, so that the placement table and the connecting mechanism can be moved out of the test box through the opening. The present invention allows the staff to place and take the vehicle-mounted touch screen outside the test box, avoiding the problem that the space in the test box is small, which makes it inconvenient for the staff to place and take the vehicle-mounted touch screen, thereby improving the convenience of the test operation and improving the work efficiency.

DETAILED DESCRIPTION
[0010] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.
[0011] The terms "first", "second", "third", "fourth", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", "third", "fourth", etc. are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0012] The inventive concept of this application is described here: During actual use, the inventor found that the existing vehicle-mounted touch screen needs to undergo quality inspection tests during the production process, which are generally divided into touch tests and display tests. Because the display problem of the screen is easily affected by external light, the staff needs to place the vehicle-mounted touch screen in a test box with very dim light for testing, and then close the box door for testing. After the test is completed, the box door is opened and the vehicle-mounted touch screen is taken out from the placement groove. Since the space in the test box is small and contains a testing mechanism, it is not convenient for the staff to place and take the vehicle-mounted touch screen, which reduces work efficiency and affects people's use. After the test is completed, there may be imprints on the surface of the vehicle-mounted touch screen, which needs to be further erased by the staff, reducing production efficiency and increasing the labor intensity of the staff.
[0013] Based on this, the inventor provides a vehicle-mounted touch screen production and testing device, which allows staff to place and take the vehicle-mounted touch screen outside the test box, avoiding the problem of small space inside the test box, which makes it inconvenient for staff to place and take the vehicle-mounted touch screen. It improves the convenience of testing operations, improves work efficiency, and can erase the imprints on the surface of the vehicle-mounted touch screen, reducing the labor intensity of staff and improving the overall practicality and ease of operation of the device.
[0014] The following is combined with Figures 1 to 12 , a vehicle-mounted touch screen production and testing device provided by this application is described in detail through specific embodiments and application scenarios.
[0015] Reference Figure 1 、 Figure 2 and Figure 5 , a vehicle-mounted touch screen production and testing device, comprising: a test box 100, a cover plate 200, a placement table 300, a linkage mechanism 400 and a connection mechanism 500; Specifically, the testing device further includes a workbench 10 , with support legs 20 installed at the four corners of the bottom of the workbench 10 to support the workbench 10 ; the test box 100 is installed at one end of the top of the workbench 10 .
[0016] Reference Figure 1 and Figure 2 , an opening 110 is formed on one side of the test box 100; The cover plate 200 is slidably connected to the test box 100 and is used to open or close the opening 110; Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 8 The top of the test box 100 at the opening 110 is provided with a moving groove 140, and the cover 200 is slidably arranged in the moving groove 140. A guide rod 150 is installed on the top of the moving groove 140, and a guide groove 230 is provided on the top of the cover 200 to slide with the guide rod 150. A limit block 160 is installed on one end of the guide rod 150 located in the guide groove 230. The limit block 160 is provided to prevent the guide rod 150 from separating from the cover 200, and the sliding cooperation between the guide rod 150 and the guide groove 230 makes the cover 200 move up and down more stably; wherein, the number of guide rods 150 can be multiple, preferably, the number of guide rods 150 is 2, which are symmetrically located at the two ends of the top of the moving groove 140. Similarly, the number of guide grooves 230 is also 2.
[0017] The test box 100 is used in conjunction with the cover plate 200, and the opening 110 can be closed during testing to prevent external light from affecting the testing process, thereby improving the production testing efficiency of the vehicle-mounted touch screen.
[0018] Reference Figure 1 and Figure 2 The placement table 300 is used to place the vehicle-mounted touch screen, and the placement table 300 can be moved into or out of the test box 100 through the opening 110; Specifically, a first linear guide rail 30 is installed on the workbench 10, and the first linear guide rail 30 can extend into the test box 100 through the opening 110. The placement table 300 is slidably set on the first linear guide rail 30. The specific structure and working principle of the first linear guide rail 30 are common knowledge, so they are not described in detail here; preferably, the placement table 300 is installed on the slider of the first linear guide rail 30, and the placement table 300 is driven to move by the first linear guide rail 30, so that the placement table 300 can move into or out of the test box 100 through the opening 110.
[0019] The placement table 300 can be moved in and out of the test box 100, making it convenient for the staff to place the vehicle touch screen on the placement table 300 and then send it into the test box 100 for testing. After the test is completed, it can be easily moved out, which improves the convenience and efficiency of the test operation.
[0020] Reference Figure 1 and Figure 2 One end of the linkage mechanism 400 is located in the test box 100, and the other end of the linkage mechanism 400 is connected to the cover plate 200. When the placement platform 300 moves into the test box 100 and continues to move, the placement platform 300 drives the cover plate 200 to move downward through the linkage mechanism 400 to close the opening 110. When the placement platform 300 is located in the test box 100 and moves toward the opening 110, the placement platform 300 drives the cover plate 200 to move upward through the linkage mechanism 400 to open the opening 110. Specifically, through the linkage mechanism 400, the placement table 300 can continue to move after moving into the test box 100 to drive the cover 200 to close the opening 110, and can drive the cover 200 to open the opening 110 when moving toward the opening 110. This design of automatically opening and closing the opening 110 does not require additional manual operation of the cover 200, reduces the operating steps, and improves the degree of automation of the test process. At the same time, it can also avoid the situation where the test results are affected by the failure to close the opening due to manual negligence.
[0021] Reference Figure 2 and Figure 5 The connecting mechanism 500 is set on the placement table 300. When the placement table 300 moves into the test box 100 and continues to move, the placement table 300 is connected to the linkage mechanism 400 through the connecting mechanism 500. When the placement table 300 is located in the test box 100 and moves toward the opening 110, the connecting mechanism 500 is disconnected from the linkage mechanism 400 so that the placement table 300 can be moved out of the test box 100.
[0022] Specifically, the connecting mechanism 500 can be connected to the linkage mechanism 400 after the placement table 300 moves into the test box 100 to achieve locking, thereby driving the cover 200 to move downward to close the opening 110; and when the placement table 300 needs to be moved out of the test box 100, the placement table 300 first drives the linkage mechanism 400 to move together through the connecting mechanism 500, and drives the cover 200 to move upward through the linkage mechanism 400 to open the opening 110, and then the connecting mechanism 500 is disconnected from the linkage mechanism 400 to achieve unlocking, so that the placement table 300 can be smoothly moved out without being hindered by the cover 200; this design ensures the smoothness of the movement of the placement table 300 before and after the entire test, and realizes the linkage function with the cover 200 without affecting its independent removal, thereby improving the overall practicality and ease of operation of the device.
[0023] Among them, reference Figure 1 、 Figure 2 and Figure 11 In this embodiment, a testing mechanism 600 is provided in the testing box 100 , and the testing mechanism 600 is used to test the vehicle-mounted touch screen.
[0024] Specifically, the testing mechanism 600 works inside the test box 100, which can avoid interference from external environmental factors such as light, temperature, and vibration on the test results. At the same time, mechanized detection replaces manual visual or manual operation, which can eliminate subjective errors in human judgment; the testing mechanism 600 can cooperate with the placement table 300 to ensure that the testing mechanism 600 can perform detection under normal working conditions of the vehicle-mounted touch screen, avoiding misjudgment due to poor contact; the testing mechanism 600 can cooperate with the first linear guide rail 30. After the first linear guide rail 30 sends the placement table 300 into the test box 100, the testing mechanism 600 can start the detection without manual intervention, realizing the automatic connection of "feeding-detection" and reducing waiting time.
[0025] Test Maker 600 achieves automation, precision, and anti-interference in the testing process, ultimately meeting the stringent quality control requirements for automotive touch screen production.
[0026] Reference Figure 1 、 Figure 2 and Figure 11 , in this embodiment, the testing mechanism 600 includes a moving component 610 and a stylus tip 620; The moving assembly 610 is connected to the test box 100, and the stylus pen head 620 is detachably connected to the moving assembly 610, so that the stylus pen head 620 can be easily replaced. The moving component 610 is used to drive the stylus pen head 620 to move; Specifically, refer to Figure 11The moving assembly 610 includes a second linear guide rail 611, a first telescopic member 612, a second telescopic member 613 and a connecting plate 614; two second linear guide rails 611 are provided, and the second linear guide rails 611 are arranged horizontally, and the conveying direction of the second linear guide rail 611 is the same as the conveying direction of the first linear guide rail 30; one end of the second linear guide rail 611 is connected to the upper part of the side away from the opening 110 in the test box 100, and the two second linear guide rails 611 are located at both ends of the upper part of one side in the test box 100; a sliding device is provided between the two second linear guide rails 611 There is a same first telescopic member 612, and both ends of the first telescopic member 612 are connected to the sliders of the two second linear guide rails 611 respectively; the first telescopic member 612 can be a ball screw pair or a rodless cylinder. In this embodiment, the first telescopic member 612 is preferably a rodless cylinder, and the slider of the first telescopic member 612 can move in the vertical direction of the conveying direction of the second linear guide rail 611; the second telescopic member 613 is vertically installed on the slider of the first telescopic member 612, and the second telescopic member 613 can be a cylinder, an electric cylinder or a hydraulic cylinder. In this embodiment, the second telescopic member 613 is vertically installed on the slider of the first telescopic member 612. The component 613 is preferably a cylinder; the telescopic end of the second telescopic component 613 is connected to a connecting plate 614, and the connecting plate 614 is detachably connected to the stylus pen head 620; the second telescopic component 613 is used to drive the stylus pen head 620 to move up and down; the first telescopic component 612 is used to drive the stylus pen head 620 to move in a direction perpendicular to the conveying direction of the second linear guide rail 611; wherein, the specific structure and working principle of the second linear guide rail 611, the first telescopic component 612 and the second telescopic component 613 are common knowledge, so they are not described in detail here; through the second linear guide rail The rail 611, the first telescopic member 612, and the second telescopic member 613 implement multi-axis linkage control of the stylus tip 620, ensuring that the stylus tip 620 accurately stops at any position on the vehicle-mounted touch screen. The stylus tip 620 can be precisely positioned in multiple dimensions and tested using a preset program or a visual recognition system to generate an optimal path. The second linear guide rail 611, the first telescopic member 612, and the second telescopic member 613 enable precise movement of the stylus tip 620, ensuring minimal error in its operating trajectory, meeting the high touch accuracy requirements of vehicle-mounted touch screens. The stylus tip 620 is used to detect the vehicle-mounted touch screen.
[0027] Specifically, when the vehicle-mounted touch screen is in the powered working state, the detection signal of the stylus tip 620 can be effectively received and fed back by the touch screen, ensuring the validity of the detection data; the specific structure and working principle of the stylus tip 620 are common knowledge, so they will not be described in detail here.
[0028] Programmed detection can be achieved through the mobile component 610. That is, after the detection path and operation steps are preset, the device can automatically complete a comprehensive detection of the vehicle-mounted touch screen without manual point-by-point operation. This not only reduces labor costs, but also greatly improves the detection speed and adapts to the batch detection needs of the production line.
[0029] Reference Figure 2 、 Figure 3 and Figure 8 In this embodiment, a wiper 210 is provided at the bottom of the cover plate 200 , and the wiper 210 is used to wipe dust and / or imprints on the surface of the vehicle-mounted touch screen.
[0030] Specifically, when the placement table 300 is moved into the test box 100 through the opening 110, the surface of the vehicle-mounted touch screen on the placement table 300 can contact the wiper 210 at the bottom of the cover plate 200 to wipe off the dust on the surface of the vehicle-mounted touch screen, thereby avoiding false touches or missed detections during detection by the stylus tip 620; when the placement table 300 is moved out of the test box 100 through the opening 110, the surface of the vehicle-mounted touch screen on the placement table 300 can contact the wiper 210 at the bottom of the cover plate 200 to wipe off the imprint on the surface of the vehicle-mounted touch screen, thereby avoiding affecting the appearance of the vehicle-mounted touch screen; if the surface of the vehicle-mounted touch screen is re-contaminated with dust during detection, the dust and the imprint can be wiped off together by the wiper 210; preferably, the wiper 210 is made of a soft elastic material, such as microfiber, sponge, etc., to automatically clean the surface of the vehicle-mounted touch screen, thereby providing an accurate detection basis for the testing mechanism 600 and protecting the appearance of the vehicle-mounted touch screen. At the same time, it is compatible with the automated design of the device, thereby reducing product scrapping due to surface defects and reducing production costs.
[0031] Reference Figure 2 、 Figure 4 、 Figure 6 、 Figure 9 and Figure 10 In this embodiment, the linkage mechanism 400 includes a rack 410, a linkage assembly 420 and a threaded rod 430; The rack 410 is slidably connected to the test box 100, and the rack 410 can be plugged into the connecting mechanism 500. The rack 410 is transmission-connected to the linkage assembly 420, and the linkage assembly 420 is transmission-connected to the threaded rod 430. The threaded rod 430 is threadedly connected to the cover plate 200. Specifically, refer to Figure 4 、 Figure 6 and Figure 9The rack 410 is horizontally slidably arranged on the side of the test box 100 away from the opening 110. The rack 410 passes through the test box 100. A sliding hole 120 is horizontally opened on the test box 100. The rack 410 is located in the sliding hole 120 and slides with the sliding hole 120. A guide bar 413 is installed on at least one side of the adjacent gear teeth on the rack 410. In this embodiment, guide bars 413 are installed on both sides of the adjacent gear teeth on the rack 410. A guide hole 130 is horizontally opened on the test box 100 and communicates with the sliding hole 120. The guide bar 413 slides with the guide hole 130, thereby improving the rack 410. Stability of movement; a stopper 414 is provided on one end of the rack 410 located outside the test box 100, and the stopper 414 cannot pass through the sliding hole 120 and the guide hole 130, and the stopper 414 does not interfere with the first gear 421 of the linkage assembly 420; when the placement table 300 is located in the test box 100 and moves toward the opening 110, when the stopper 414 contacts the side of the test box 100, the placement table 300 continues to move toward the opening 110, and the rack 410 cannot continue to move due to the obstruction of the stopper 414. At this time, the connection mechanism 500 and the rack 410 will be disconnected to achieve unlocking.
[0032] The plug-in cooperation between the connecting mechanism 500 and the rack 410 requires the placement table 300 to reach a specific position to be triggered. This mechanical interlocking design avoids accidental opening and closing of the cover 200 due to misoperation, thereby improving the safety of the device.
[0033] Reference Figure 8 , the threaded rod 430 is arranged vertically, and there is a gap between the threaded rod 430 and the test box 100. One end of the threaded rod 430 extends into the movable groove 140 and is threadedly connected to the cover 200. A threaded groove 220 is provided on the top of the cover 200. The threaded rod 430 is threadedly connected to the threaded groove 220, and the cover 200 is driven to move up and down by the rotation of the threaded rod 430; the threaded connection between the threaded rod 430 and the threaded groove 220 has a self-locking function. When the placement table 300 stops moving, the threaded rod 430 can fix the cover 200 in the current position, and the opening 110 can be kept closed without an additional locking mechanism, ensuring that external light will not affect the test process during the test.
[0034] The linkage assembly 420 is used to transmit the power of the rack 410 to the threaded rod 430, so that the threaded rod 430 drives the cover plate 200 to move up and down.
[0035] Specifically, refer to Figure 10The linkage assembly 420 includes a first gear 421, a first rotating shaft 422, a first bevel gear 423, a second bevel gear 424, a second rotating shaft 425, a third bevel gear 426 and a fourth bevel gear 427; the linkage assembly 420 is located outside the test box 100, the first gear 421 is meshed and connected with the rack 410, and the first gear 421 is arranged horizontally; the first gear 421 is connected to the first rotating shaft 422, and the first rotating shaft 422 is arranged vertically, and the top of the first rotating shaft 422 is connected to the first bevel gear 423, and the first bevel gear 423 is arranged horizontally; the first bevel gear 423 is meshed and connected with the second bevel gear 424, and the second bevel gear 424 is arranged vertically; the second bevel gear 4 24 is connected to the second rotating shaft 425, and the second rotating shaft 425 is arranged horizontally; the other end of the second rotating shaft 425 is connected to the third bevel gear 426, and the third bevel gear 426 is arranged vertically; the third bevel gear 426 is meshed and connected with the fourth bevel gear 427, and the fourth bevel gear 427 is arranged horizontally, and the fourth bevel gear 427 is connected to the threaded rod 430; wherein, a fixed block is rotatably installed on the first rotating shaft 422 and the second rotating shaft 425, and one side of the fixed block is connected to the test box 100, and the first rotating shaft 422 and the second rotating shaft 425 are supported by the fixed block; preferably, a protective cover (not shown in the figure) is provided on the outside of the linkage assembly 420 to protect the linkage assembly 420.
[0036] Through the movement of the rack 410, the first gear 421 is driven to rotate, the first gear 421 drives the first rotating shaft 422 to rotate, thereby driving the first bevel gear 423 to rotate, the first bevel gear 423 drives the second bevel gear 424 to rotate, thereby driving the second rotating shaft 425 to rotate, and then driving the third bevel gear 426 to rotate, the third bevel gear 426 drives the fourth bevel gear 427 to rotate, thereby driving the threaded rod 430 to rotate, thereby driving the cover 200 to move up and down.
[0037] The linkage mechanism 400 achieves the accuracy of mechanical transmission, the automation of movement synchronization, the efficiency of space utilization and the stability of environmental control, which significantly improves the efficiency and reliability of vehicle-mounted touch screen production testing.
[0038] Reference Figure 2 and Figure 5 In this embodiment, the connecting mechanism 500 includes a mounting block 510, a connecting slot 520 and a plug-in assembly 530; The mounting block 510 is connected to the placement table 300. A connecting groove 520 capable of connecting to the rack 410 is formed on the side of the mounting block 510 facing the rack 410. A plug-in assembly 530 is provided in the connecting groove 520. The plug-in assembly 530 can be plug-fitted with the rack 410 .
[0039] Specifically, the mounting block 510 is connected to the lower part of the placement table 300; by setting the connection groove 520, a precise insertion path is provided for the rack 410, ensuring the docking accuracy of the rack 410 and the plug-in component 530, avoiding connection failure or component damage due to inaccurate alignment; the connection is formed by the plug-in cooperation between the plug-in component 530 and the rack 410, which can effectively transmit pulling force and pushing force. In the process of the placement table 300 pushing the rack 410 to move, this connection method ensures the high efficiency of power transmission and avoids slipping or loosening.
[0040] When the placement table 300 is completely moved into the test box 100 and continues to move inward, the rack 410 is gradually inserted into the connection groove 520 and triggers the locking of the plug-in component 530. Then the cover 200 begins to descend. When the placement table 300 moves in the opposite direction to a specific position, the plug-in component 530 and the rack 410 are disconnected to achieve unlocking, and the cover 200 rises synchronously. This automated connection ensures the continuity of the test process, reduces manual intervention, and improves production efficiency.
[0041] Reference Figure 2 and Figure 5 In this embodiment, the plug-in assembly 530 includes a second sliding groove 531, an insert block 532 and a second elastic member 533; The second sliding groove 531 is connected to the connecting groove 520. An inserting block 532 is slidably provided in the second sliding groove 531. A second elastic member 533 is connected between the inserting block 532 and the inner wall of the second sliding groove 531. The insert block 532 can be plug-fitted with the rack 410 .
[0042] Specifically, there are multiple second sliding grooves 531. In this embodiment, there are two second sliding grooves 531. Second sliding grooves 531 are provided on both sides of the connecting groove 520. The second elastic member 533 is provided to enable the plug block 532 to float in the second sliding groove 531. When the rack 410 is inserted into the connecting groove 520, the plug block 532 can automatically adjust its position through elastic deformation to compensate for the manufacturing error or assembly deviation between the rack 410 and the connecting groove 520, thereby achieving reliable plug-in fit. At the moment when the plug block 532 contacts the rack 410, the second elastic member 533 can absorb the impact energy and reduce the noise and wear caused by the rigid collision. This buffering effect prolongs the service life of the plug block 532 and the rack 410. service life; the second elastic member 533 is preferably a spring; the number of the second elastic members 533 can be set to multiple, which can be flexibly set according to actual use requirements, and this embodiment does not limit this; when the stop block 414 contacts the side of the test box 100, the placement table 300 continues to move toward the opening 110, and the rack 410 cannot continue to move due to the obstruction of the stop block 414. At this time, the rack 410 applies a reverse force to the plug block 532, forcing the plug block 532 to overcome the elastic force of the second elastic member 533 and retract into the second sliding groove 531, thereby releasing the locked state and realizing automatic unlocking without the need for additional control signals, and does not rely on electronic components or complex control systems, thereby reducing the probability of failure and improving the reliability and durability of the equipment.
[0043] Reference Figure 2 、 Figure 6 and Figure 9 In this embodiment, the rack 410 is provided with a connecting block 411 that can be inserted into the connecting groove 520, and the connecting block 411 is provided with a slot 412 that can be plugged into and matched with the inserting block 532; Specifically, there are multiple slots 412. In the present embodiment, there are two slots 412, which are compatible with the plug block 532. Preferably, the plug block 532 has at least one inclined surface on the side opposite to the connecting block 411. In the present embodiment, the connecting block 411 has an inclined surface on the side close to the plug block 532, so that the plug block 532 can be retracted into the connecting groove 520 through the inclined surface of the connecting block 411. Preferably, the connecting block 411 and the rack 410 can be manufactured by an integrated casting or forging process to reduce assembly links and improve structural strength.
[0044] Among them, reference Figure 6 A first inclined surface 4121 and a second inclined surface 4122 are provided on a side of the slot 412 away from the rack 410. The first inclined surface 4121 is close to the bottom of the slot 412, and the inclination angle of the first inclined surface 4121 is smaller than the inclination angle of the second inclined surface 4122. When the insert block 532 is inserted into the slot 412, the insert block 532 quickly enters the slot 412 through the second inclined surface 4122 and the first inclined surface 4121 to complete the locking. Specifically, the shape of the plug block 532 extending to the connecting groove 520 is set to be a right-angled trapezoid, and the inclined surface of the trapezoid can be the same as the inclination angle of the first inclined surface 4121, and the shape of the plug block 532 located in the second sliding groove 531 is set to be square; the shape of the lower part of the slot 412 is roughly the same as the shape of the plug block 532 extending to the connecting groove 520; when the plug block 532 is fully embedded in the slot 412, the inclined surface of the plug block 532 is in contact with the first inclined surface 4121 to form a self-locking structure, so that when the placement table 300 continues to drive the rack 410 to move in the direction away from the opening 110, the plug block 532 can push the rack 410 to continue moving, and the self-locking structure can effectively resist the vibration or impact load that may be generated during the test.
[0045] The dual inclined surfaces (first inclined surface 4121 and second inclined surface 4122) of slot 412 are designed to form a stepped guiding structure; the second inclined surface 4122 has a larger inclination angle (the angle with the horizontal plane is 60°-75°), which provides quick guidance in the initial stage, so that the plug 532 can be quickly aligned with the entrance of slot 412, reducing insertion resistance and allowing smooth insertion even if there is a slight position deviation of the placement table 300; the first inclined surface 4121 has a smaller inclination angle (the angle with the horizontal plane is 30°-45°), which provides fine guidance when the plug 532 approaches the bottom of slot 412, ensuring that the plug 532 is fully embedded and tightly locked; the design of the first inclined surface 4121 and the second inclined surface 4122 utilizes the angle difference to form a "coarse adjustment + fine adjustment" insertion process, significantly improving the locking efficiency.
[0046] When the placement platform 300 is located in the test box 100 and moves toward the opening 110 , the second inclined surface 4122 has an inclination angle greater than that of the first inclined surface 4121 , thereby preventing the inserting block 532 from rapidly separating from the slot 412 .
[0047] Specifically, the angular difference between the double inclined surfaces (the first inclined surface 4121 and the second inclined surface 4122) produces asymmetric unlocking resistance. When the placement platform 300 moves in the opposite direction, the larger angle of the second inclined surface 4122 causes the plug block 532 to be subjected to a larger lateral component of force, so that the plug block 532 needs to overcome a higher friction force to disengage from the slot 412 (that is, the inclined surface of the plug block 532 and the adjacent vertical surface are stuck between the connection between the first inclined surface 4121 and the second inclined surface 4122, and a larger reverse force is required to pull the plug block 532 out along the second inclined surface 4122). This design effectively prevents mislocking caused by vibration or accidental collision during testing, ensuring connection stability. Only when the placement platform 300 applies sufficient reverse force (exceeding the pre-tightening force of the second elastic member 533) can the plug block 532 slide out along the second inclined surface 4122, achieving controllable separation.
[0048] In this embodiment, when unlocking, the larger inclination angle of the second inclined surface 4122 ensures that the inserting block 532 will not be disengaged until the placement platform 300 moves in the opposite direction for a certain distance, so that the cover 200 has enough time to complete the upward movement.
[0049] Reference Figure 2 、 Figure 7 and Figure 12 In this embodiment, the placement platform 300 includes a placement slot 310, an elastic support component 320 and a power-on component 330; A placement groove 310 is provided on the placement platform 300, an elastic support component 320 is provided at the bottom of the placement groove 310, and a power-on component 330 is provided on the placement platform 300; The placement slot 310 is used to place the vehicle-mounted touch screen; Specifically, the placement slot 310 is opened on the top of the placement platform 300; the number of the placement slots 310 is several, so that several vehicle-mounted touch screens can be placed on the placement platform 300, which is convenient for batch testing; in this embodiment, the number of the placement slot 310 is 1.
[0050] The elastic support assembly 320 is used to elastically support the vehicle-mounted touch screen for easy handling; Specifically, by setting the elastic support component 320, the vehicle-mounted touch screen is elastically supported, so that the vehicle-mounted touch screen is not completely in contact with the bottom of the placement groove 310, and the height of the vehicle-mounted touch screen is 3-5 mm higher than the top surface of the placement platform 300, which is convenient for the staff to take the vehicle-mounted touch screen; when the placement platform 300 enters the test box 100 through the opening 110, the cover plate 200 presses the vehicle-mounted touch screen downward, so that the surface of the vehicle-mounted touch screen is in close contact with the wiping block 210, and the dust on the surface of the vehicle-mounted touch screen is wiped off; in the process of the placement platform 300 being moved out of the test box 100 through the opening 110, the cover plate 200 presses the vehicle-mounted touch screen downward, The surface of the vehicle-mounted touch screen on the platform 300 can be in close contact with the wiper 210 at the bottom of the cover plate 200 to erase the imprint on the surface of the vehicle-mounted touch screen; and when the second telescopic member 613 drives the stylus pen head 620 to contact the surface of the vehicle-mounted touch screen, the elastic support component 320 can prevent the stylus pen head 620 from making hard contact with the surface of the vehicle-mounted touch screen and causing damage to the surface of the vehicle-mounted touch screen; wherein, the two sides of the bottom of the cover plate 200 can be set with smooth transitions, and the two sides of the wiper block 210 are set with inclined surfaces, so that the surface of the vehicle-mounted touch screen can squeeze the wiper block 210 upward along the inclined surface of the wiper block 210, thereby making the surface of the vehicle-mounted touch screen in close contact with the wiper block 210.
[0051] The power-on component 330 is used to supply power to the vehicle-mounted touch screen.
[0052] Specifically, a wiring groove 340 is opened on one side of the placement slot 310, and the wiring groove 340 is used to accommodate the plug wire of the vehicle-mounted touch screen, and the plug wire is connected to the plug wire; Reference Figure 2 and Figure 7 The power-on component 330 includes a first interface 331, a second interface 332 and a second connector 333; the first interface 331 is located at the end of the wiring groove 340 away from the placement groove 310, and the first interface 331 can be connected to the plug on the vehicle-mounted touch screen plug cable. A second interface 332 is installed on one side of the upper part of the placement platform 300. The first interface 331 and the second interface 332 are connected by wires, and the wires are located inside the placement platform 300; the second interface 332 is located above the mounting block 510, and a second connector 333 that can be connected to the second interface 332 is installed on the inner wall of the test box 100, and the second connector 333 can be connected to an external power supply through wires.
[0053] When the vehicle-mounted touch screen is placed in the placement groove 310, the plug of the vehicle-mounted touch screen is connected to the first interface 331, so that the plug wire of the vehicle-mounted touch screen is placed in the wiring groove 340. When the placement table 300 is moved into the test box 100 and the second interface 332 is connected to the second connector 333, the vehicle-mounted touch screen can be powered, and then the vehicle-mounted touch screen can be tested through the stylus head 620.
[0054] Reference Figure 2 and Figure 7 In this embodiment, the elastic support assembly 320 includes a first sliding groove 321, a support block 322 and a first elastic member 323; The first sliding groove 321 is connected to the bottom of the placement groove 310. A support block 322 is slidably provided in the first sliding groove 321. A first elastic member 323 is connected between the support block 322 and the inner wall of the first sliding groove 321. The support block 322 is used to support the vehicle-mounted touch screen.
[0055] Specifically, multiple first sliding grooves 321 can be set. In this embodiment, four first sliding grooves 321 can be set at the bottom of a placement groove 310; the sliding cooperation of the support block 322 in the first sliding groove 321 and the first elastic member 323 together constitute a damping system, which effectively attenuates the vibration generated during the test and avoids deformation of the screen due to excessive click pressure of the stylus head 620; and through the setting of the first elastic member 323, it is ensured that the vehicle-mounted touch screen always maintains contact with the support block 322 during the picking and placing process, avoiding position displacement caused by shaking; preferably, the first elastic member 323 is a spring, and the number of the first elastic members 323 can be set to multiple, which can be flexibly set according to actual usage requirements, and this embodiment does not limit this.
[0056] The surface of the support block 322 that contacts the vehicle-mounted touch screen can be covered with soft materials such as silicone and polyurethane, which can not only provide sufficient supporting force but also avoid scratching the tempered film or coating on the surface of the vehicle-mounted touch screen, thereby realizing flexible support and quick placement of the vehicle-mounted touch screen, and providing a precise, efficient and durable support solution for the production and testing of vehicle-mounted touch screens.
[0057] In this embodiment, an electrical control cabinet (not shown) is provided on one side of the workbench 10. The electrical control cabinet (not shown) contains various electrical components, system programs, operation panels, etc., which control the entire device to perform actions according to established programs, process various sensors and signal sources, and output corresponding program instructions. The operator can input data from the vehicle-mounted touch screen into the system program through the external touch screen. At the same time, the external indicator light and warning light display the operating status of the device, and the external button can pause or stop the operation of the device.
[0058] Working principle: When in use, the staff places the vehicle-mounted touch screen in the placement groove 310 of the placement table 300, and connects the plug of the vehicle-mounted touch screen to the first interface 331, so that the plug wire of the vehicle-mounted touch screen is placed in the wiring groove 340, and then the placement table 300 is transported by the first linear guide 30. When the placement table 300 enters the test box 100 through the opening 110, the cover 200 presses the vehicle-mounted touch screen downward, so that the surface of the vehicle-mounted touch screen is in close contact with the wiper 210, and the vehicle The dust on the surface of the touch screen is wiped off. After the placement table 300 enters the test box 100, it continues to move through the first linear guide rail 30. When the connecting block 411 is inserted into the connecting groove 520, the inserting block 532 is squeezed by the connecting block 411 and inserted into the second sliding groove 531. Then, when the inserting block 532 is opposite to the slot 412, the second elastic member 533 allows the inserting block 532 to quickly align with the entrance of the slot 412, and the inserting block 532 is inserted into the slot 412, forming a self-locking structure. The placement table 300 is connected to the rack 410, and then the placement table 300 continues to drive the rack 410 to move deeper into the test box 100. When the rack 410 moves, it drives the first gear 421 to rotate, and the first gear 421 drives the first rotating shaft 422 to rotate, thereby driving the first bevel gear 423 to rotate, and the first bevel gear 423 drives the second bevel gear 424 to rotate, thereby driving the second rotating shaft 425 to rotate, and then drives the third bevel gear 426 to rotate, and the third bevel gear 426 drives the fourth bevel gear 427 to rotate, thereby driving the threaded rod 430 to rotate, thereby driving the cover 200 to descend, closing the opening 110 to prevent external light from affecting the testing process. The placement table 300 continues to move until the second interface 332 is connected to the second connector 333, powering the vehicle-mounted touch screen, and then multi-axis linkage control of the stylus pen head 620 is realized through the second linear guide 611, the first telescopic member 612 and the second telescopic member 613, so that the stylus pen head 620 can detect the vehicle-mounted touch screen; After the test is completed, the first linear guide 30 drives the placement table 300 to move toward the opening 110, and the second interface 332 is separated from the second joint 333. At this time, the plug block 532 is still plugged into the slot 412. The placement table 300 drives the rack 410 to move in the opposite direction, and finally drives the cover 200 to rise, opening the opening 110. Until the stopper 414 contacts the side of the test box 100, the placement table 300 continues to move toward the opening 110, and the rack 410 cannot continue to move due to the obstruction of the stopper 414. At this time, the rack 410 applies a reverse force to the plug block 532, forcing the plug block 532 to overcome the first stopper 414. The elastic force of the second elastic member 533 retracts into the second sliding groove 531, thereby releasing the locked state and achieving automatic unlocking, so that the placement platform 300 is separated from the rack 410, and then the first linear guide 30 continues to move the placement platform 300. In the process of the placement platform 300 moving out of the test box 100 through the opening 110, the surface of the vehicle-mounted touch screen on the placement platform 300 can contact the wiper 210 at the bottom of the cover 200 to erase the imprint on the surface of the vehicle-mounted touch screen. After the placement platform 300 is moved out of the test box 100, with the cooperation of the support block 322 and the first elastic member 323, it is convenient for the staff to pick up the vehicle-mounted touch screen.
