DETAILED DESCRIPTION
[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0026] Please refer to Figure 1-4 , Figure 1 A schematic diagram of a three-dimensional structure of a device for measuring an LED light of an instrument panel, wherein the interior is opened after the back plate is removed. A device for measuring an LED light of an instrument panel comprises a shell 1, wherein the shell 1 has a cavity for detecting an LED light of an instrument panel, wherein the shell 1 provides a closed environment for detection, wherein a needle bed 2 is provided at the bottom of the shell 1, wherein a top plate 3 is provided above the needle bed 2, wherein a plurality of pressure columns 4 are provided at the bottom of the top plate 3 for pressing the instrument panel, wherein a moving component 100 is provided in the shell 1, wherein the top plate 3 moves up and down under the action of the moving component 100, wherein the needle bed 2 is a non-standard test auxiliary fixture for testing online components by using electrical properties to check for manufacturing defects and component failures, and wherein the instrument panel to be detected is placed on the needle bed 2 On the top, the needle bed 2 is used in conjunction with the top plate 3 to perform fixed detection on the LED lights of the automobile dashboard. During the detection, the upper computer 5, the lower computer 6 and the image recognition camera 7 are also required. The upper computer 5, the lower computer 6 and the image recognition camera 7 are all prior art, and conventional models in the field can be used to implement the technical solution of the present application. Preferably, the lower computer 6 is installed in a box at the bottom of the shell 1, the upper computer 5 is electrically connected to the lower computer 6 and the image recognition camera 7 respectively, and the lower computer 6 is electrically connected to the instrument panel for controlling the lighting of the instrument panel. The image recognition camera 7 is installed at the top of the shell 1, and its connecting line passes through the through hole at the top of the shell 1. The image recognition camera 7 is used to take pictures of the instrument panel in the shell 1 during detection.
[0027] The upper computer 5 refers to a computer that can directly issue control commands, usually a PC / host computer / mastercomputer / upper computer, and displays various signal changes (hydraulic pressure, water level, temperature, etc.) on the screen. The lower computer 6 is a computer that directly controls the equipment to obtain the equipment status, usually a PLC / single chip microcomputer / slave computer / lower computer and the like. The command issued by the upper computer 5 is first given to the lower computer 6, and the lower computer 6 then interprets the command into a corresponding timing signal to directly control the corresponding equipment. The lower computer 6 reads the equipment status data from time to time, converts it into a digital signal and feeds it back to the upper computer 5.
[0028] In this embodiment, the moving component 100 includes a cylinder 110 and a fixed block 120. Preferably, two cylinders 110 and two fixed blocks 120 are provided, respectively on both sides of the shell 1. The two cylinders 110 are respectively fixed on the two side walls of the shell 1. The top plate 3 is connected to the fixed block 120. The telescopic end of the cylinder 110 drives the fixed block 120 to move up and down in the shell 1, thereby driving the top plate 3 to move up and down in the shell 1, and cooperates with the needle bed 2 to fix the car dashboard to detect it.
[0029] In this embodiment, the front side or the rear side of the shell 1 is set to an openable baffle 11. After opening the baffle 11, it is convenient to put in and take out the car dashboard or replace the equipment parts in the shell 1. The opening method of the baffle 11 can be set to slide open or rotate open. For example, the baffle 11 is rotatably connected to the shell 1 through a pin shaft and can be rotated horizontally left and right or up and down. The baffle 11 can also be set to be slidably connected to the shell 1, such as an up and down sliding connection, and a slide groove is opened on both side walls of the shell 1. The baffle 11 slides up and down along the slide groove to open or close the inside of the shell 1.
[0030] Preferably, we choose to connect the baffle 11 to the shell 1 in an up and down sliding manner, which just cooperates with the driving action of the cylinder 110, saving manpower to automatically open or close the baffle 11. Specifically, a connecting piece 130 is also provided between the telescopic end of the cylinder 110 and the fixed block 120. The baffle 11 is connected to the connecting piece 130, and a detachable connection with screws can be adopted. The connecting piece 130 is used to connect the baffle 11 and slide up and down under the driving action of the cylinder 110. In order not to affect the image recognition camera 7 on the top of the shell 1 to take pictures of the instrument panel below, the connecting piece 130 is configured in a frame form, that is, the image recognition camera 7 on the top can take pictures of the instrument panel below from the hollowed-out part in the middle of the connecting piece 130. The two ends of the connecting piece 130 are respectively connected to the telescopic ends of the cylinder 110, and the side of the connecting piece 130 is connected to the baffle 11.
[0031] Slide rails 140 are respectively arranged on the two side walls inside the shell 1, and sliders 150 are arranged on both sides of the connecting member 130. The sliders 150 are slidably connected with the slide rails 140. By setting the sliders 150 and the slide rails 140, the cylinder 110 is more stable when driving parts that need to slide up and down, such as the connecting member 130 and the fixing block 120.
[0032] Since the LED light is divergent and the distance between the LED lights is relatively close, the LED lights interfere with each other. Therefore, a diffuse reflection plate 8 is provided between the top plate 3 and the instrument panel on the needle bed 2 to filter the LED light. The diffuse reflection plate 8 is connected to the fixed block 120 through the fixed component 160, and can move up and down with the fixed block 120 after being driven by the cylinder 110. The fixed block 120 is preferably L-shaped, and the bottom end of the fixed block 120 is connected to the top plate 3, and the side plate of the fixed block 120 is connected to the fixed component 160.
[0033] The fixing assembly 160 includes an n-shaped support block 161, which is connected to the side plate of the fixing block 120. The top of the support block 161 is threadedly connected to a lead screw 162, and the bottom of the lead screw 162 is connected to a connecting block 163. Both sides of the connecting block 163 are slidably connected to the support block 161. The bottom of the connecting block 163 passes through the top plate 3 to connect to the diffuse reflection plate 8, that is, there is a hole on the top plate 3 for the connecting block 163 to pass through. The support block 161 is adjusted to slide up and down by the lead screw 162, thereby driving the diffuse reflection plate 8 to move up and down, and adjusting the distance between the diffuse reflection plate 8 and the instrument panel to achieve the best display effect.
[0034] In order to facilitate the replacement of the top plate 3 and the needle bed 2, a plurality of positioning pins 9 are provided on both sides of the bottom needle bed 2 in the shell 1 to fix the needle bed 2 and facilitate replacement. The top plate 3 is detachably connected to the bottom end of the fixed block 120, for example, by using screws to connect the top plate 3 and the fixed block 120, so as to facilitate the disassembly and replacement of the top plate 3.
[0035] The working principle of this utility model:
[0036] The image recognition camera 7 is fixed on the top of the equipment, and the instrument panel to be tested is placed inside the equipment. When the cylinder 110 is pressed down, the block will be driven down. After the block drops to the bottom, a closed environment is formed inside the equipment to prevent external light interference. Then the upper computer 5 controls the lower computer 6 to light up the instrument panel LED light. The upper computer 5 controls the camera to take pictures, and the color and on and off status of the LED light are identified through the photos to determine whether it is a good product, thereby transforming the traditional method of manually measuring LEDs into an automatic detection method.
[0037] Different models of automobile dashboards need to be configured with a corresponding set of top plates 3 and needle beds 2. The top plates 3 and needle beds 2 are replaceable devices, which can be quickly replaced through positioning pins 9. In this way, they are compatible with most products. Since the light from LED lights diverges and the distance between LED lights is close, the LED lights interfere with each other. Therefore, a diffuse reflection plate 8 is placed between the dashboard and the top plate 3. The distance between the diffuse reflection plate 8 and the dashboard can be adjusted through the diffuse reflection plate 8 fixing component 160 to achieve the best display effect.
[0038] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
