[0002] An in-vehicle central control screen refers to a touch screen or display screen installed on the center console of an automobile, which is used to display various information of the vehicle and control certain functions of the vehicle. It usually has functions such as navigation, entertainment, vehicle information display and control, etc. During the production process of the in-vehicle central control screen, in order to ensure the integrity of the functions, it is necessary to detect its various functions, including screen detection, touch detection, button detection, etc. Since there are many items to be detected, in the prior art, multiple devices are usually required to detect the various functions of the central control screen respectively, resulting in a time-consuming and cumbersome testing process, frequent replacement of testing devices, thus affecting the testing efficiency and increasing the testing cost. Content of the Utility Model

[0003] In view of this, the utility model provides an in-vehicle central control screen automatic detector that integrates various detection items such as the screen detection function, touch detection function, button and knob detection function of the in-vehicle central control screen.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] An in-vehicle central control screen automatic detector includes: a machine platform, a detection receiving platform, a panel detection mechanism and an image detection mechanism. A first linear module is arranged on the machine platform; the detection receiving platform is arranged at the output end of the first linear module and is used for placing the central control screen to be detected; the panel detection mechanism and the image detection mechanism are arranged on the machine platform and are sequentially arranged at intervals along the conveying direction of the first linear module; wherein, the panel detection mechanism includes a panel support arranged on the machine platform, a first lifting module arranged on the panel support and above the detection receiving platform, and a mounting plate connected to the output end of the first lifting module. The mounting plate is connected with a screen touch detection component and a knob button detection component; the image detection mechanism includes an image support arranged on the machine platform, a second lifting module arranged on the image support and above the detection receiving platform, and a camera component connected to the output end of the second lifting module.

[0006] In the above technical scheme, when inspecting the vehicle-mounted central control screen, the product to be inspected is first placed on the inspection platform, and then the first linear module drives the inspection platform to move under the panel inspection mechanism and the image inspection mechanism for inspection. When the inspection platform moves to under the panel inspection mechanism, the first lifting module drives the mounting plate to descend, so that the screen touch detection component is close to the central control screen, and performs brightness, flicker and touch detection on the central control screen, and then switches to the knob and button detection component to detect the validity of the buttons and knobs on the central control screen; then, when the inspection platform moves to under the image detection mechanism, the second lifting module drives the camera assembly to descend to make it close to the central control screen, and detects the silk screen and screen integrity of the central control screen. After all inspections are completed, the first linear module drives the inspection platform to push back, and the central control screen is taken out to complete the inspection.

[0007] Optionally, in a possible implementation, the screen touch detection component includes a first fixing frame, a color analyzer disposed on the first fixing frame, and a plurality of touch test units, wherein the plurality of touch test units are disposed around the periphery of the color analyzer.

[0008] In the above technical solution, by cleverly combining the color analyzer with multiple touch test units and surrounding them, the simultaneous detection of screen display quality and touch performance is achieved, avoiding the cumbersome process of separate equipment testing in the traditional detection method, greatly improving the detection efficiency. In addition, the surround design allows each touch test unit to independently test different areas of the screen, which helps to quickly locate and identify potential problem areas on the screen, and can also adapt to detection needs of different sizes.

[0009] Optionally, in a possible implementation, the touch test unit includes a touch driver and a touch head elastically clamped on the first fixing frame, the touch driver is used to squeeze the touch head, and a plurality of the touch drivers are mounted on the first fixing frame through a support plate.

[0010] In the above technical solution, the output end of the touch driver squeezes the touch head to make the touch head move and touch the screen. That is, the touch driver squeezes the touch head by precisely controlling the force, simulating the scenario of the user pressing the screen with his finger in actual operation. This not only ensures the accuracy of the test results, but also helps to discover touch problems that may be caused by long-term pressing or pressing with different forces. The elastically arranged touch head can also ensure that the touch driver can automatically reset when it retracts.

[0011] Optionally, in a possible implementation, the knob and button detection assembly includes a second fixing frame, and a button detection unit and a knob detection unit spaced apart on the second fixing frame, and the button detection unit has a front detection portion and a side detection portion.

[0012] In the above technical solution, by integrating the key detection unit and the knob detection unit on the same second fixing bracket, it can independently detect the keys and knobs on the screen, and complete the testing of two different types of input components without replacing or adjusting the device; the specially designed front detection part and side detection part of the key detection unit can detect the keys on the front and side of the central control screen on the same device, thereby effectively improving the detection range.

[0013] Optionally, in a possible implementation manner, the front detection part includes a first pressing driving member, a connecting plate arranged at the output end of the first pressing driving member, and a plurality of front pressing heads spaced apart on the connecting plate; the side detection part includes a plurality of second pressing driving members and side pressing heads arranged at the output ends of the second pressing driving members.

[0014] In the above technical solution, the front detection part uses the first pressing driving member to drive the connecting plate to move, and then drives the plurality of front pressing heads to synchronously or independently press the front pressing area of the central control screen. At the same time, when there are keys on the side of the central control screen, the central control screen can be rotated so that the second pressing driving member can drive the side pressing heads to press and detect the keys on the side of the central control screen, so that the detection of the key detection unit can be more comprehensive and accurate.

[0015] Optionally, in a possible implementation manner, the knob detection unit includes an electric rotating jaw and clamping blocks arranged at two output ends of the electric rotating jaw, and the two clamping blocks are arranged oppositely and a "T" - shaped groove is arranged on the opposite surface thereof.

[0016] In the above technical solution, the electric rotating jaw has the functions of clamping and rotating. By clamping and rotating the knob, the functional effectiveness of the knob can be detected. The two clamping blocks are arranged oppositely and are equipped with "T" - shaped grooves, which can effectively adapt to different sizes of knobs and increase the contact area with the knob, ensuring that the knob can be effectively clamped and realizing stable and precise clamping.

[0017] Optionally, in a possible implementation manner, a light - shielding plate and a light - shielding driving member are further arranged on the panel support. The light - shielding plate is slidably clamped on the panel support and is located between the panel detection mechanism and the image detection mechanism, and the light - shielding driving member is used to drive the lifting of the light - shielding plate.

[0018] In the above technical solution, the setting of the light - shielding plate and its precise control by the light - shielding driving member can effectively isolate the light interference between the panel detection mechanism and the image detection mechanism when they are working. For the detection environment requirements of the screen, it can significantly improve the detection accuracy and stability and ensure the reliability of the detection results.

[0019] Optionally, in a possible implementation, the camera assembly includes a camera fixing plate, and a plurality of silk screen detection cameras, dark point detection cameras and light sources provided on the camera fixing plate.

[0020] In the above technical solution, the camera assembly integrates cameras of different detection types, including silk screen detection cameras and dark point detection cameras, enabling a set of equipment to meet multiple detection requirements at the same time. Among them, the silk screen detection camera focuses on detecting the silk screen quality on the surface of the central control screen or other objects to be detected, and the dark point detection camera is specifically used to capture and identify defects such as dark spots and bright spots on the screen to ensure the accuracy and reliability of the detection results. In addition, the setting of the light source can provide a stable and uniform lighting environment for the detection camera, improve the imaging quality, and ensure the accuracy of the detection results.

[0022] In the above technical solution, through the plurality of positioning columns on the positioning table, the central control screen can be accurately positioned and fixed. With the locking function of the locking member, it can be ensured that the central control screen remains stable and does not shake during the detection process. In addition, the positioning table is designed with a rotation function and is driven to rotate by the rotation driving member, so that the central control screen can be detected at different angles and positions, which not only meets the requirements of various detection scenarios, but also can observe and analyze the performance of the central control screen from multiple angles during a single detection process, improving the comprehensiveness and accuracy of the detection.

[0023] Optionally, in a possible implementation, two groups of the first linear modules are arranged at intervals and in parallel. Second linear modules are provided on both the panel support and the portrait support. The second linear module is perpendicular to the first linear module. The first lifting module and the second lifting module are respectively arranged at the output ends of the two groups of the second linear modules.

[0024] In the above technical solution, the setting of the two groups of the first linear modules can place two detection platforms at the same time, and the setting of the two groups of the second linear modules enables the first lifting module and the second lifting module to reciprocate between the two detection platforms, that is, two central control screens can be detected at the same time, so as to further improve the detection efficiency of the central control screen.

Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0042] Please refer to Figure 1, this embodiment provides an automatic detection machine for vehicle-mounted central control screens, including: a machine platform 1, a detection receiving platform 2, a panel detection mechanism 3, and an image detection mechanism 4. A first linear module 11 is provided on the machine platform 1; the detection receiving platform 2 is arranged at the output end of the first linear module 11 and is used for placing the central control screen to be detected; the panel detection mechanism 3 and the image detection mechanism 4 are arranged on the machine platform 1 and are sequentially arranged at intervals along the conveying direction of the first linear module 11; wherein, the panel detection mechanism 3 includes a panel support 31 arranged on the machine platform 1, a first lifting module 32 arranged on the panel support 31 and located above the detection receiving platform 2, and a mounting plate 33 connected to the output end of the first lifting module 32.

[0043] To describe the movements of each mechanism more clearly, this embodiment establishes a spatial rectangular coordinate system for auxiliary explanation. Specifically, the first linear module 11 of this embodiment is arranged along the Y-axis direction, and the detection receiving platform 2 is fixedly arranged at the output end of the first linear module 11. Among them, the first linear module 11 is a conventional device in the prior art, such as a linear motor, and its specific structure will not be elaborated here. The panel detection mechanism 3 and the image detection mechanism 4 are arranged at intervals along the conveying direction of the first linear module 11, and the detection sequence of the two can be flexibly adjusted according to actual needs.

[0044] When detecting the vehicle-mounted central control screen in this embodiment, first place the product to be detected on the detection receiving platform 2, and then the first linear module 11 drives the detection receiving platform 2 to move to the lower parts of the panel detection mechanism 3 and the image detection mechanism 4 respectively for detection. When the detection receiving platform 2 moves below the panel detection mechanism 3, the first lifting module 32 drives the mounting plate 33 to descend, so that the screen touch detection component 34 approaches the central control screen, and the brightness, flicker degree and touch detection of the central control screen are carried out. Then, switch to the knob button detection component 35 to detect the effectiveness of the buttons and knobs of the central control screen; then, when the detection receiving platform 2 moves below the image detection mechanism 4, the second lifting module 42 drives the camera component 43 to descend to approach the central control screen, and the silk printing and screen integrity of the central control screen are detected. After all the detections are completed, the first linear module 11 drives the detection receiving platform 2 to push back, and the central control screen is taken out to complete the detection.

[0045] It should be noted that the panel bracket 31 and the portrait bracket 41 are fixed on the machine 1 at intervals, and the first lifting module 32 is installed on the panel bracket 31. The first lifting module 32 includes a first lifting drive member 321, a first lifting card plate 322 and a first guide rail slider unit 323. The first lifting card plate 322 is installed on the panel bracket 31, the first lifting drive member 321 is fixed to the first lifting card plate 322, and the output end of the first lifting drive member 321 is connected to the mounting plate 33, and the mounting plate 33 is connected to the first lifting card plate 322 through the first guide rail slider unit 323, thereby improving the lifting stability of the mounting plate 33. When the mounting plate 33 is lifted or lowered, it can synchronously drive the screen touch detection component 34 and the knob button detection component 35 to lift or lower.

[0046] Please refer to Figure 2 The second lifting module 42 includes a second lifting drive and a second lifting card, the second lifting card is installed on the image support 41, the second lifting drive is fixed to the second lifting card, and the output end of the second lifting drive is connected to the camera assembly 43. The first lifting drive 321 and the second lifting drive can be linear drive mechanisms such as cylinders or screw transmission mechanisms.

[0047] Please refer to Figure 2 , Figure 4 and Figure 5 In this embodiment, the screen touch detection component 34 and the knob button detection component 35 are sequentially arranged along the Y-axis direction. The screen touch detection component 34 includes a first fixing frame 341, a color analyzer 342 arranged on the first fixing frame 341, and a plurality of touch test units 343. The plurality of touch test units 343 are arranged around the periphery of the color analyzer 342. Among them, the detection end of the color analyzer 342 and the detection end of the touch test unit 343 both pass through the bottom of the first fixing frame 341, so as to be directly opposite to the central control screen for convenient detection.

[0048] This embodiment achieves simultaneous detection of screen display quality and touch performance by cleverly combining the color analyzer 342 with multiple touch test units 343 and surrounding them, avoiding the cumbersome process of separate devices required for separate testing in traditional detection methods, and greatly improving detection efficiency. In addition, the surround design allows each touch test unit 343 to independently test different areas of the screen, which helps to quickly locate and identify potential problem areas on the screen, and can also adapt to detection needs of different sizes.

[0049] Please refer to Figure 4 and Figure 5, in this embodiment, the touch test unit 343 includes a touch drive 3431 and a touch head 3432 elastically clamped on the first fixing bracket 341. The touch drive 3431 is used to squeeze the touch head 3432. A plurality of touch drives 3431 are mounted on the first fixing bracket 341 through a support plate 344. Specifically, a through hole for the color analyzer 342 to pass through is provided in the middle of the support plate 344. A plurality of touch drives 3431 are arranged at intervals in a circular array around the through hole. Each touch drive 3431 corresponds to a touch head 3432, and a top block opposite to the touch head 3432 is provided at the output end of the touch drive 3431. The touch drive 3431 squeezes the touch head 3432 through the top block. In addition, the touch head 3432 is elastically clamped on the first fixing bracket 341 through an elastic member such as a spring.

[0050] The touch drive 3431 in this embodiment is a cylinder. Its output end squeezes the touch head 3432 to make the touch head 3432 move and touch the screen. That is, the touch drive 3431 squeezes the touch head 3432 by precisely controlling the force, simulating the scenario of a user pressing the screen with a finger during actual operation. This not only ensures the accuracy of the test results but also helps to discover touch problems that may be caused by long-term pressing or pressing with different forces. The elastically arranged touch head 3432 can also ensure that the touch drive 3431 can automatically reset when retracting.

[0051] Please refer to Figure 2 and Figure 3 , in this embodiment, the knob button detection component 35 includes a second fixing bracket 351, and a button detection unit 352 and a knob detection unit 353 arranged at intervals on the second fixing bracket 351. The button detection unit 352 has a front detection part 3521 and a side detection part 3522. Specifically, the second fixing bracket 351 can be connected to the first fixing bracket 341 or to the mounting plate 33. The front detection part 3521 and the side detection part 3522 are both independent detection components and can act independently.

[0052] In this embodiment, by integrating the button detection unit 352 and the knob detection unit 353 on the same second fixing bracket 351, it can independently detect the buttons and knobs on the screen, and complete the tests of two different types of input components without replacing or adjusting the device. The specially designed front detection part 3521 and side detection part 3522 of the button detection unit 352 can detect the buttons on the front and side of the central control screen on the same device, thus effectively improving the detection range.

[0053] Please refer to Figure 3, the front detection unit 3521 of this embodiment includes a first pressing drive member 3521a, a connecting plate 3521b disposed at the output end of the first pressing drive member 3521a, and a plurality of front pressing heads 3521c spaced apart on the connecting plate 3521b; the side detection unit 3522 includes a plurality of second pressing drive members 3522a and side pressing heads 3522b disposed at the output ends of the second pressing drive members 3522a. The first pressing drive member 3521a can be a cylinder. The first pressing drive member 3521a is fixed to the second fixing bracket 351, and its output end is connected to the connecting plate 3521b. The plurality of front pressing heads 3521c are spaced apart according to a certain rule, such as in a rectangular array or a linear arrangement, etc., and are in the same plane. The specific arrangement method can be flexibly set according to the button positions of the actual central control screen. Similarly, the side detection unit 3522 can also be set to a plurality according to actual needs. For example, the central control screen detected in this embodiment has two buttons on the side. Therefore, by setting two second pressing drive members 3522a and side pressing heads 3522b to align for detection.

[0054] In this embodiment, the front detection unit 3521 of this embodiment uses the first pressing drive member 3521a to drive the connecting plate 3521b to move, thereby driving the plurality of front pressing heads 3521c to synchronously or independently press the front pressing area of the central control screen. At the same time, when there are buttons on the side of the central control screen, the central control screen can be rotated so that the second pressing drive member 3522a can drive the side pressing head 3522b to press and detect the buttons on the side of the central control screen. In this way, the detection of the button detection unit 352 can be more comprehensive and accurate.

[0055] Please refer to Figure 2 and Figure 3 , in this embodiment, the knob detection unit 353 includes an electric rotary gripper 3531 and clamping blocks 3532 disposed at the two output ends of the electric rotary gripper 3531. The two clamping blocks 3532 are disposed opposite to each other, and a "T"-shaped groove is provided on the opposite surface thereof. Specifically, the electric rotary gripper 3531 is fixed to the second fixing bracket 351. It is a conventional device in the prior art, and its specific structure will not be described in detail here. The two clamping blocks 3532 can be fixed by screws and other parts. In addition, the electric rotary gripper 3531 can be set to a plurality according to actual needs. For example, the central control screen of this embodiment has two knobs. Therefore, electric rotary grippers 3531 are provided at the corresponding two positions.

[0056] The electric rotary gripper 3531 of this embodiment has the functions of clamping and rotating. By clamping and rotating the knob, the functional effectiveness of the knob can be detected. The two clamping blocks 3532 are disposed opposite to each other and are equipped with "T"-shaped grooves, which can effectively adapt to different sizes of knobs and increase the contact area with the knobs, ensuring that the knobs can be effectively clamped and achieving stable and accurate clamping.

[0057] Please refer to Figure 2 and Figure 4 In this embodiment, a light-shielding plate 311 and a light-shielding driving member 312 are further provided on the panel bracket 31. The light-shielding plate 311 is slidably clamped on the panel bracket 31 and is located between the panel detection mechanism 3 and the image detection mechanism 4. The light-shielding driving member 312 is used to drive the lifting of the light-shielding plate 311. Specifically, the light-shielding driving member 312 can be a cylinder. The light-shielding driving member 312 can be installed on the panel bracket 31 through a fixing bracket, and its output end drives the lifting of the light-shielding plate 311 to open or close the moving channel of the detection receiving platform 2 between the panel detection mechanism 3 and the image detection mechanism 4. In addition, the light-shielding plate 311 can be slidably connected to the panel bracket 31 through a second guide rail slider unit 313, so as to effectively improve the stability of the lifting process of the light-shielding plate 311.

[0058] The setting of the light-shielding plate 311 in this embodiment and its precise control through the light-shielding driving member 312 can effectively isolate the light interference between the panel detection mechanism 3 and the image detection mechanism 4 when they are working. For the detection environment requirements of the screen, it can significantly improve the accuracy and stability of the detection and ensure the reliability of the detection results.

In addition, an additional light source 434 can be added to the image bracket 41 to further improve the brightness.

[0060] The camera assembly 43 in this embodiment integrates cameras of different detection types, including a silk screen detection camera 433 and a dark spot detection camera 432, so that a set of equipment can meet multiple detection requirements at the same time. Among them, the silk screen detection camera 433 focuses on detecting the silk screen quality on the surface of the central control screen or other objects to be detected, and the dark spot detection camera 432 is specifically used to capture and identify defects such as dark spots and bright spots on the screen to ensure the accuracy and reliability of the detection results. In addition, the setting of the light source 434 can provide a stable and uniform lighting environment for the detection cameras, improve the imaging quality, and ensure the accuracy of the detection results.

[0061] It should be noted that both the silk screen detection camera 433 and the dark spot detection camera 432 are integrated with a vision automatic detection system, which can automatically read the product barcode from the tooling board and query relevant information through a computer program, and can automatically control the second lifting module 42 to move above the central control screen to be detected through a computer program for automatic detection and automatic judgment of the test results.

[0062] Please refer to Figure 7, in this embodiment, the receiving platform 2 includes a support base 21, a positioning platform 22 rotatably mounted on the support base 21, a plurality of positioning posts 23 provided on the positioning platform 22, a locking member 24 provided on the positioning platform 22 and used for locking the central control screen, and a rotation driving member 25 provided on the support base 21 and used for driving the positioning platform 22 to rotate. Specifically, the support base 21 is fixed to the output end of the first linear module 11. One end of the positioning platform 22 is rotatably mounted on the support base 21 through a rotating shaft, and the other end is a free end and is also supported by the support base 21. The locking member 24 includes a locking cylinder 241 and a pressing block 242. The pressing block 242 is rotatably provided on the output shaft of the locking cylinder 241. When locking, the pressing block 242 is rotated to be located above the central control screen, and then the locking cylinder 241 drives the pressing block 242 to move and lock the central control screen. In addition, an insertion interface matching the central control screen is also provided on the support base 21, which is electrically connected to the central control screen and used for supplying power to the central control screen.

[0063] In this embodiment, through the plurality of positioning posts 23 on the positioning platform 22, the central control screen can be accurately positioned and fixed. Combining with the locking function of the locking member 24, it can ensure that the central control screen remains stable and does not shake during the detection process. In addition, the positioning platform 22 is designed with a rotation function and is driven to rotate by the rotation driving member 25, so that the central control screen can be detected at different angles and positions. This not only meets the requirements of various detection scenarios, but also can observe and analyze the performance of the central control screen from multiple angles during a single detection process, improving the comprehensiveness and accuracy of the detection.

[0064] Please refer to Figure 1 , in this embodiment, there are two groups of first linear modules 11 arranged at intervals and in parallel.
