Description

Technical Field

[0001] This invention relates to the field of positioning and clamping device technology, and more specifically, to a flexible floating positioning and adaptive clamping device for assembling vehicle screens. Background Technology

[0002] The assembly technology of in-vehicle screens is a core link that has been constantly evolving with the development of automotive intelligence and display technology. Early in-vehicle displays were mostly small-sized, single-function independent modules, but now screens have developed towards larger sizes and higher resolutions, with a high degree of integration of display functions.

[0003] In the assembly process of the display module with the mid-frame and back frame, existing processes typically involve first precisely positioning the mid-frame before gripping and assembling the display module. However, due to the inevitable slight deviation between the gripping mechanism and the positioning system, rigid assembly methods can easily transfer stress to the screen, causing damage. Furthermore, if the mid-frame itself is deformed, direct assembly will also increase the risk of screen damage. Summary of the Invention

[0004] This invention provides a flexible floating positioning and adaptive clamping device for assembling vehicle screens, solving the technical problem of assembly-related damage in related technologies.

[0005] This invention provides a flexible floating positioning and adaptive clamping device for assembling vehicle screens, comprising: Multiple positioning and clamping mechanisms are respectively set in multiple side areas of the middle frame to position and limit the middle frame; Each positioning and clamping mechanism includes multiple moving blocks and pressing members on each moving block. The moving block has a channel inside, one end of the pressing member extends into the channel and can be reversibly connected to the channel, and the other end of the pressing member is used to press against the side of the middle frame. A linear actuator is connected to the middle frame to drive the moving block to move toward the side of the middle frame so that the pressing part presses against the side of the middle frame. After being pressed, the pressing part moves relative to the channel and acts on the auxiliary part through the medium in the channel, causing the auxiliary part to be displaced. The auxiliary component is equipped with a detection mating part; It also includes a detection and positioning mechanism, which is used to cooperate with the detection and mating part to determine whether there is deformation on the side of the middle frame after the pressing part presses against the side of the middle frame based on the displacement of the auxiliary part.

[0006] As a further optimization of the present invention, multiple movable blocks constitute a side area corresponding to one side of the middle frame, and the side area is divided into a fixed middle area and adjustable selection areas at both ends. The central fixed area is composed of multiple movable blocks that are fixedly connected together, while the two adjustable selection areas at both ends are composed of movable blocks that are rotatably connected by hinges. The movable blocks at the desired selection area are adjusted according to the corresponding side length of the middle frame and are limited by positioning components.

[0007] As a further optimization of the present invention, the positioning component includes a limiting frame, a rod, and a positioning pin. The limiting frame is installed on a moving block between the fixed area in the middle and the adjustable selection areas at both ends, and is also installed on a moving block at the adjustable selection areas at both ends. The rod slides through the limiting frame and is positioned by the positioning pin to limit the position of the rod, thereby selecting a corresponding number of moving blocks according to the length of the corresponding side of the middle frame.

[0008] As a further optimization of the present invention, the channel is a right-angle channel, the pressing member is a pressing rod, one end of the pressing rod slides into one opening of the right-angle channel, the auxiliary member slides into the other opening of the right-angle channel, the inside of the right-angle channel is filled with liquid, and one end of the pressing rod that extends into the inside of the right-angle channel is reversibly connected to the right-angle channel through a pressing spring.

[0009] As a further optimization of the present invention, the auxiliary component includes a moving rod and a return spring. One end of the moving rod slides into the interior of the right-angle channel and is reversibly connected to the right-angle channel through the return spring. When the pressing rod continuously extends into the interior of the right-angle channel and compresses the pressing spring, the moving rod extends out through the action of liquid, stretching and storing energy in the return spring.

[0010] As a further optimization of the present invention, the detection and positioning mechanism includes a linear driver, a connecting block, a common connection block, a pressure sensor, and a probe. The output end of the linear driver is fixedly connected to the connecting block. The connecting block has a sliding cavity on the side facing the common connection block. The common connection block slides into the interior of the sliding cavity and is connected to the sliding cavity through the pressure sensor. One end of the probe is fixedly connected to the common connection block, and the other end is used to slide through the insertion port.

[0011] As a further optimization of the present invention, the detection mating part is a socket opened on the moving rod. After the pressing rod and the middle frame are pressed and stabilized, the linear driver drives the probe to pass through the socket. If the side of the middle frame is not flat, the extension height of each pressing rod is different from that of each moving rod, resulting in different heights of each socket. When the probe cannot pass through the corresponding socket, it is subject to resistance. If the pressure sensor detects a non-set value, it is judged as abnormal and the assembly is stopped.

[0012] As a further optimization of the present invention, a linear motion device is provided above the middle frame. The linear motion device is connected to a suction cup through a floating module. The suction cup is used to adsorb the display module. The linear motion device drives the display module to move vertically toward the middle frame for floating assembly.

[0013] As a further optimization of the present invention, the linear motion device is mounted on the XYZ module, which can drive the suction cup to pick up and assemble the display module.

[0014] As a further optimization of the present invention, the middle frame is placed on the base plate, the linear actuator is assembled on the base plate, and the bottom of the moving block is slidably connected to the base plate by a slider.

[0015] The beneficial effects of this invention are as follows: 1. The flexible floating positioning and adaptive clamping device for vehicle screen assembly described in this invention, through the cooperation of a pressure rod, a right-angle channel, a liquid medium and a moving rod, enables the pressure rod to achieve flexible adaptive clamping when pressing against the side of the middle frame. The pressure rod is not rigidly fixed, but automatically adjusts the pressure according to the actual shape of the side of the middle frame through the combined action of liquid pressure transmission and spring restoring force, thereby reducing the damage to the screen caused by rigid assembly.

[0016] 2. The flexible floating positioning and adaptive clamping device for vehicle screen assembly described in this invention, by opening an insertion port on the moving rod and cooperating with the measuring rod and pressure sensor of the detection positioning mechanism, can detect the flatness of each side while positioning the middle frame. If the middle frame is deformed, the extension height of each moving rod is inconsistent, causing the insertion port to be misaligned. When the measuring rod cannot pass through, the pressure sensor will feed back an abnormal signal and stop the assembly. This realizes the integrated function of positioning and detection, and detection and positioning, reducing the problem of display module assembly damage caused by middle frame deformation.

[0017] 3. The flexible floating positioning and adaptive clamping device for vehicle screen assembly described in this invention, after the probe completes the deformation detection, remains in the inserted state and plays a limiting and locking role on the moving rod. Then, through the liquid reaction, it acts on the pressure rod, so that the pressure rod stably maintains the pressure against the middle frame. That is, the detection mechanism simultaneously undertakes the dual functions of deformation detection and positioning stability.

[0018] 4. The flexible floating positioning and adaptive clamping device for vehicle screen assembly described in this invention divides the side area into a fixed central area and adjustable selectable areas at both ends, and uses a hinge rotation connection with positioning components for limiting. This allows the device to flexibly adjust the length of each side area according to different sizes of the frame, making it versatile and compatible, and adaptable to the assembly needs of various specifications of vehicle screens.

[0019] 5. The flexible floating positioning and adaptive clamping device for vehicle screen assembly described in this invention connects the suction cup and the linear motion device through the floating module, enabling the display module to automatically compensate for minor positional deviations during the assembly process, further reducing the risk of rigid contact. It works in conjunction with the side deformation detection function of the middle frame to improve the assembly quality and yield of the vehicle screen from the three stages of positioning, detection and assembly.

Detailed Implementation

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] Example 1 like Figures 1 to 7 As shown, this embodiment of the invention provides a flexible floating positioning and adaptive clamping device for assembling vehicle screens, including multiple positioning and clamping mechanisms 2, detection and positioning mechanisms 4, linear actuators 3, linear motion devices 6, floating modules 7, suction cups 8, and a base plate 5.

[0030] There are multiple positioning clamping mechanisms 2, and multiple sets of positioning clamping mechanisms 2 are combined to form four side areas applicable to the middle frame 1. The positioning clamping mechanisms 2 at each side area are combined to limit the side of the middle frame 1. The four side areas together position and limit the middle frame 1. It should be noted that the middle frame 1 here refers to the middle frame structure that needs to be positioned and clamped during the assembly of the vehicle screen, and its shape is usually rectangular.

[0031] Each positioning and clamping mechanism 2 includes multiple moving blocks 21, multiple pressing members (pressing rods 22 in this embodiment), multiple pressing springs 24, multiple auxiliary members and positioning members. The multiple moving blocks 21 constitute a side area corresponding to one side of the middle frame 1. This side area is divided into a fixed area in the middle and adjustable selection areas at both ends.

[0032] The central fixed area is composed of multiple movable blocks 21 fixedly connected together and used as a whole unit. The two adjustable selection areas at both ends are composed of movable blocks 21 rotatably connected by hinges 23. The hinges 23 can realize relative rotation between two adjacent movable blocks 21.

[0033] In actual use, when the side length of the middle frame 1 changes, the operator can adjust the number of movable blocks 21 at both ends of the adjustable selection area by rotating the hinge 23 according to the actual length of the corresponding side of the middle frame 1. That is, select the movable blocks 21 to unfold or fold, so that the length of the entire side area matches the side length of the middle frame 1. After the adjustment is completed, the movable blocks 21 at the selection area are limited and fixed by the positioning component.

[0034] like Figure 6As shown, the movable block 21 has a channel inside. In this embodiment, as a preferred implementation, the channel is a right-angle channel 211, that is, the channel is approximately L-shaped or right-angled. It should be noted that the channel of the present invention is not limited to a right-angled bend shape. In other embodiments, the channel can also be an arc bend, an obtuse bend, or any other connecting path shape that can realize the transmission of liquid pressure, as long as the displacement generated by the pressure on the pressing member can be transmitted to the auxiliary member through the medium.

[0035] One end of the pressure rod 22 slides into one opening of the right-angle channel 211, and the auxiliary component slides into the other opening of the right-angle channel 211. The pressure rod 22 presses vertically against the side of the middle frame 1. One end of the pressure rod 22 extending into the right-angle channel 211 is reversibly connected to the right-angle channel 211 through the pressure spring 24. The inside of the right-angle channel 211 contains a medium. In this embodiment, the medium is preferably a liquid, such as hydraulic oil, water, or other fluids with good pressure transmission performance.

[0036] As an optional implementation, a piston head (not shown in the figure) is provided at one end of the pressure rod 22 that extends into the right-angle channel 211. The piston head is slidably sealed with the inner wall of the right-angle channel 211 to ensure that the liquid pressure can be effectively applied to the auxiliary component. One end of the pressure spring 24 is fixedly connected to the pressure rod 22, and the other end is fixedly connected to the inner wall of the right-angle channel 211 to provide restoring force after the pressure rod 22 is compressed.

[0037] The middle frame 1 is connected to a linear actuator 3, which is used to fix the moving block 21 in the fixed area to drive the moving block 21 to move toward the side of the middle frame 1. The linear actuator 3 can be an actuator element that can provide linear driving force, such as a cylinder, a hydraulic cylinder, or an electric push rod.

[0038] like Figure 4 , Figure 6 and Figure 7 As shown, when the linear actuator 3 extends, the moving block 21 of its driving fixed area moves towards the side of the middle frame 1. The moving block 21 drives all the pressing rods 22 on it to move synchronously, so that the ends of the pressing rods 22 gradually press against the side of the middle frame 1. As the linear actuator 3 continues to extend, the pressing rods 22 are subjected to the reaction force of the middle frame 1 and retract into the right-angle channel 211 relative to the moving block 21, compressing the pressing spring 24. At the same time, the pressure is transmitted to the auxiliary component through the liquid in the right-angle channel 211, causing the auxiliary component to extend out of the right-angle channel 211 and generate displacement. During this process, the pressing force of the pressing rods 22 is flexible. The pressing rods 22 are not completely rigidly fixed, but floating pressing is achieved through the combined action of the pressing spring 24 and the liquid, thereby avoiding rigid impact or damage to the middle frame 1.

[0039] like Figures 4 to 7 As shown, the auxiliary components include a moving rod 25 and a return spring 26. One end of the moving rod 25 slides into the interior of the right-angle channel 211 and is reversibly connected to the right-angle channel 211 via the return spring 26. Specifically, when the pressing rod 22 continuously extends into the interior of the right-angle channel 211 and compresses the pressing spring 24, the liquid pressure inside the right-angle channel 211 increases. The liquid acts on the end of the moving rod 25, pushing the moving rod 25 to extend out of the right-angle channel 211. At the same time, it stretches the return spring 26 to store energy. When the external force on the pressing rod 22 is released, under the combined restoring force of the pressing spring 24 and the return spring 26, both the pressing rod 22 and the moving rod 25 return to their initial positions.

[0040] The movable rod 25 is provided with a detection mating part. In this embodiment, the detection mating part is a socket 251 opened along the diameter direction of the movable rod 25, that is, the socket 251 passes through the rod body of the movable rod 25.

[0041] The positioning component includes a limiting frame 27, a plug rod 28, and a positioning pin 29. The limiting frame 27 is installed on a moving block 21 between the central fixed area and the two adjustable selection areas at both ends, and is also installed on each moving block 21 at the two adjustable selection areas at both ends. The limiting frame 27 has a through hole through which the plug rod 28 passes.

[0042] The insertion rod 28 slides through the limiting frame 27 and is positioned by the positioning pin 29. Specifically, the limiting frame 27 and the insertion rod 28 are respectively provided with pin holes. When the insertion rod 28 is inserted into the predetermined position, the insertion end of the positioning pin 29 slides through the pin hole of the limiting frame 27 and the pin hole of the insertion rod 28, thereby limiting and fixing the position of the insertion rod 28. According to the length of the corresponding side of the middle frame 1, the operator selects the corresponding number (i.e. the required number) of moving blocks 21 and inserts the insertion rod 28 into the limiting frame 27 corresponding to the selected area, thereby limiting and fixing the moving block 21 of the selected area.

[0043] Each of the four sides is provided with a detection and positioning mechanism 4. The detection and positioning mechanism 4 is used to cooperate with the detection mating part (i.e., the insertion port 251). After the pressing part presses against the side of the middle frame 1, the displacement of the moving rod 25 is used to determine whether there is deformation on the side of the middle frame 1.

[0044] The detection and positioning mechanism 4 includes a linear driver 41, a connecting block 42, a common connecting block 43, a pressure sensor 44, and a measuring rod 45. The output end of the linear driver 41 is fixedly connected to the connecting block 42. The connecting block 42 has a sliding cavity 421 on the side facing the common connecting block 43. The common connecting block 43 slides into the interior of the sliding cavity 421 and is connected to the sliding cavity 421 through the pressure sensor 44. One end of the measuring rod 45 is fixedly connected to the common connecting block 43, and the other end is used to slide through the insertion port 251 on the moving rod 25.

[0045] The linear actuator 41 can be a rodless cylinder or a linear motor. The linear actuator 41 drives the connecting block 42, the common connecting block 43 and the measuring rod 45 to move in the direction of the side length of the middle frame 1, so that the measuring rod 45 passes through the socket 251 on the moving rod 25.

[0046] Once the pressure bar 22 is stably pressed against the middle frame 1, i.e., the middle frame 1 is stably positioned, the linear actuator 41 drives the probe 45 to move forward and pass through the socket 251. If the side of the middle frame 1 is flat and without deformation, the reaction force experienced by each pressure bar 22 when pressing against the side of the middle frame 1 is the same, and the degree to which each pressure bar 22 compresses the pressure spring 24 is the same. The length of extension of each moving rod 25 driven by the liquid is also the same. Therefore, the sockets 251 on each moving rod 25 are at the same height position, and the probe 45 can pass smoothly through all the sockets 251. At this time, the probe 45 does not experience additional resistance during the movement, and the pressure value detected by the pressure sensor 44 is the set normal value (the preset reference value).

[0047] If the side of the middle frame 1 is uneven or deformed (e.g., local protrusions, depressions, or overall bending), since there are multiple pressure rods 22 distributed along the side of the middle frame 1, the pressure rods 22 corresponding to the deformed locations will be subjected to different reaction forces. The pressure rods 22 corresponding to the protrusions will be subjected to greater pressure and retract more, while the pressure rods 22 corresponding to the depressions will be subjected to less pressure and retract less. Each pressure rod 22 extends its corresponding moving rod 25 to a different length through liquid drive, resulting in inconsistent heights of the insertion ports 251 on each moving rod 25 (i.e., a height difference). At this time, when the measuring rod 45 moves forward, it will be unable to pass through the insertion ports 251 with inconsistent heights, and the measuring rod 45 will be subjected to resistance. This resistance is transmitted to the pressure sensor 44 through the common connection block 43. If the pressure sensor 44 detects a non-set value (e.g., a pressure value exceeding a preset threshold), it will determine that the middle frame 1 is deformed, thereby avoiding damage to the display module 9 during assembly due to the deformation of the middle frame 1.

[0048] Furthermore, once the side of the middle frame 1 is flat and the measuring rod 45 passes smoothly through all the sockets 251, the measuring rod 45 remains inserted into the sockets 251. At this time, the measuring rod 45 limits the position of the moving rod 25, and the moving rod 25 is fixed by the measuring rod 45. Thus, through the liquid reaction, the pressure rod 22 is stably locked in the current pressure position, thereby achieving stable positioning and clamping of the middle frame 1. In other words, while performing the deformation detection function, the measuring rod 45 also undertakes the function of assisting in positioning and stabilization, realizing the integration of detection and positioning.

[0049] A linear motion device 6 is provided above the middle frame 1. The linear motion device 6 is connected to a suction cup 8 through a floating module 7. The suction cup 8 is used to adsorb the display module 9. It should be noted that the floating module 7 (which is a known technology and will not be described in detail here) refers to a connection structure that can provide floating compensation in at least one direction. Its function is to give the suction cup 8 a certain floating margin when it contacts the display module 9 or is assembled, so as to avoid damage caused by rigid contact.

[0050] The linear motion unit 6 drives the display module 9 to move vertically toward the middle frame 1 for floating assembly. The linear motion unit 6 is mounted on the XYZ module, which is a module that can move in three directions: X-axis, Y-axis, and Z-axis. It can drive the suction cup 8 to pick up and assemble the display module 9. Through the floating compensation effect of the floating module 7, the display module 9 can automatically adapt to small positional deviations during the process of fitting with the middle frame 1, further reducing the risk of assembly damage. At the same time, in conjunction with the above-mentioned step of detecting whether the middle frame 1 is deformed, the assembly operation of the display module 9 is only performed when it is determined that the middle frame 1 is not deformed, thereby reducing assembly damage.

[0051] The middle frame 1 is placed on the base plate 5, the linear actuator 3 is mounted on the base plate 5, and the linear driver 41 is detachably mounted on the base plate 5 so that the position of the linear driver 41 can be adjusted according to the size of different middle frames 1. That is, when a middle frame 1 of a different size is replaced, the linear driver 41 can be disassembled and reinstalled to a position that matches the current positioning and detection of the middle frame 1.

[0052] Example 2 Based on Example 1, such as Figure 3 As shown, in a further preferred embodiment, the bottom of the movable block 21 in the central fixed area is slidably connected to the base plate 5 via a slider for guidance.

[0053] Specifically, a guide groove is provided on the base plate 5 corresponding to the position of the central fixed area. A slider is fixedly connected to the bottom of the moving block 21, and the slider is slidably disposed in the guide groove. In this way, when the linear actuator 3 drives the moving block 21 in the central fixed area to move toward the side of the middle frame 1, the slider slides along the guide groove, ensuring that the moving direction of the moving block 21 is accurate and stable, so that each pressing rod 22 can accurately press the side of the middle frame 1 vertically, thereby improving the positioning accuracy.

[0054] In other embodiments, the guide structure may also adopt other common linear guide methods such as guide rail and guide block cooperation, linear bearing and guide shaft cooperation, etc. Those skilled in the art can select a suitable guide structure according to actual needs.

[0055] Work process: First, based on the dimensions of the middle frame 1 to be assembled, the operator adjusts the number of movable blocks 21 at the adjustable selection areas at both ends of each side area. By rotating the hinge 23 to unfold or fold some of the movable blocks 21, the length of each side area matches the corresponding side length of the middle frame 1. Then, the movable blocks 21 at the selection area are fixed by positioning components (limiting frame 27, insert rod 28, positioning pin 29).

[0056] Next, the middle frame 1 is placed on the base plate 5, and the linear actuator 3 is activated. The linear actuator 3 drives the moving blocks 21 of the fixed areas of each side region to move toward the side of the middle frame 1. The moving blocks 21 drive the pressing rod 22 to gradually approach and press against the side of the middle frame 1. After the pressing rod 22 is subjected to the reaction force of the middle frame 1, it retracts into the right-angle channel 211, compresses the pressing spring 24, and extends through the liquid in the right-angle channel 211 to drive the moving rod 25 to extend.

[0057] Once each pressure bar 22 has been sufficiently pressed and stabilized against the side of the middle frame 1 (for example, the pressure spring 24 has been compressed to a predetermined degree), the detection and positioning mechanism 4 of each side area is activated, and the linear driver 41 drives the measuring rod 45 to move toward the middle frame 1, attempting to pass through the socket 251 on each moving rod 25.

[0058] If all probes 45 can pass smoothly through the corresponding sockets 251 (i.e., the pressure sensor 44 detects a normal value), then it is determined that the sides of the middle frame 1 are flat and without deformation. At this time, the probes 45 remain inserted into the sockets 251, limiting the movement rod 25. The movement rod 25 reacts with the liquid to the pressure rod 22, so that the pressure rod 22 stably presses against the middle frame 1, completing the stable positioning of the middle frame 1.

[0059] If a probe 45 encounters resistance during movement and cannot pass through the socket 251 (i.e., the pressure sensor 44 detects a value other than the set value), it is determined that there is deformation on the corresponding side of the middle frame 1, and subsequent assembly operations are stopped to avoid damage to the display module 9 caused by continuing to assemble the deformed middle frame 1.

[0060] After determining that the middle frame 1 is stable and without deformation, the XYZ module drives the linear motion device 6 to move to the material picking position of the display module 9. The suction cup 8 adsorbs the display module 9, and then the XYZ module drives the linear motion device 6 to move the display module 9 above the middle frame 1. The linear motion device 6 drives the display module 9 to move vertically downward. Under the floating compensation of the floating module 7, the display module 9 floats and adheres to the middle frame 1, completing the assembly.

[0061] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
