Technical Field
[0001] This utility model relates to the field of electronic equipment testing technology, specifically to a display board programming testing device. Background Technology
[0002] In the electronic equipment manufacturing industry, the display control board (PCB) is a core display and interaction component, and its quality directly affects the user experience and market competitiveness of the product. From production to finished product, the PCB needs to go through many key processes such as programming (writing specific programs and data into electronic components), functional testing, and display status detection. Deviations in any of these processes may lead to product performance defects.
[0003] Currently, there are shortcomings in the programming and testing stages of display boards. During the programming process, some programming equipment is not equipped with a fixing device, which causes the display board to shake or shift due to factors such as equipment vibration or accidental contact during manual operation. This results in misalignment between the programming probe and the display board pins, leading to programming failure.
[0004] In terms of testing, manual testing requires personnel to manually complete steps such as button function testing and display screen verification, which is inefficient and prone to missed detections and misjudgments due to individual skill differences and work fatigue. While some automated testing equipment can improve efficiency, it is complex in structure and has high purchase, debugging, and maintenance costs. Summary of the Invention

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0026] This embodiment provides a display board programming and testing device, such as... Figures 1 to 6 As shown, the system includes a testing platform 1, within which is a programmer (not shown in the figure). This programmer, a prior art technology, has the function of programming the display board, capable of writing specific programs or data onto the board; details are omitted here. A test socket 15 for placing the display board is located on the top of the testing platform 1. The display board is situated within the test socket 15, and multiple probes are arranged at the bottom of the test socket 15. The lower ends of these probes are electrically connected to the programmer's main board inside the testing platform 1 via a flexible circuit board, forming a data transmission channel. When the display board is placed in the positioning slot, the pins on the bottom of the display board correspond one-to-one with the tops of the probes in the test socket 15. Then, the programmer is activated, and it can program the display board placed in the test socket 15 through the data transmission channel.
[0027] The testing station 1 includes a detachably connected housing 10 and a top plate 13. The programmer is located inside the housing 10, and the test socket 15 is located on top of the top plate 13. It should be noted that the test socket 15 on top of the top plate 13 adopts a replaceable design, which can quickly replace the appropriate test socket 15 according to different models or sizes of the display board, thus improving the practicality of the device.
[0028] The outer casing 10 and the top plate 13 are detachably connected by the cooperation of elastic clips 12 and hooks 14. Specifically, hooks 14 are provided at both ends of the top plate 13, and elastic clips 12 that can hook the hooks 14 are provided at both ends of the outer casing 10. By making the top plate 13 and the outer casing 10 detachably connected, when the programmer inside the outer casing 10 malfunctions, the top plate 13 can be removed in time for easy maintenance. Furthermore, placing the programmer inside the outer casing 10, with the top of the outer casing 10 sealed by the top plate 13, isolates the programmer from the outside environment, ensuring the stability of the programmer's operation.
[0029] A first control switch 11 is also provided on the outer casing 10. The first control switch 11 is electrically connected to the programmer and can be used to control the programmer to turn on or off.
[0030] Furthermore, the top plate 13 is also provided with a support frame 2 as a support unit. The support frame 2 includes two support plates 20 arranged at intervals between each other, and a connecting plate 21 connecting the two support plates 20. A pressing assembly 3 and a button testing assembly 4 are mounted on this support unit. The pressing assembly 3 is mounted on the connecting plate 21, while the button testing assembly 4 is located below the pressing assembly 3. The pressing assembly 3 and the button testing assembly 4 are connected by a transmission mechanism, and the pressing assembly 3 can cooperate with the button testing assembly 4 to fix the display board placed in the test holder 15, ensuring the stability of the display board during the programming process.
[0031] Furthermore, the pressing assembly 3 includes a first mounting plate 30, a drive rod 31, a connecting rod 32, and a pressure rod 33. The first mounting plate 30 is mounted on the connecting plate 21, the drive rod 31 is hinged to the first mounting plate 30, and the two ends of the connecting rod 32 are connected to the drive rod 31 and the pressure rod 33, respectively. It also includes a first guide sleeve 34, through which the pressure rod 33 passes, and the pressure rod 33 can move along the axial direction of the first guide sleeve 34. By providing the first guide sleeve 34, when the drive rod 31 rotates under external force, it drives the pressure rod 33 via the connecting rod 32. Under the guidance of the first guide sleeve 34, the pressure rod 33 can achieve a vertical downward or upward movement.
[0032] Furthermore, the button testing assembly 4 includes a fixed plate 40 and a pressure plate 41 arranged vertically, and the fixed plate 40 and the pressure plate 41 are connected by a positioning post 42. The fixed plate 40 is fixedly connected to the pressure rod 33. When the pressing assembly 3 is pressed down, the pressure rod 33 can drive the fixed plate 40 and the pressure plate 41 to move downward synchronously until the pressure plate 41 presses the display panel tightly onto the test base 15.
[0033] Furthermore, after the display board is programmed, the button testing component 4 can test the button functions of the display board. By simulating button operations, the accuracy and sensitivity of the button response are tested. Specifically, multiple mounting sleeves 43 are provided between the fixing plate 40 and the pressure plate 41. Each mounting sleeve 43 contains a button 44, which corresponds one-to-one with the buttons on the display board. The mounting sleeve 43 has an interface for an external air pipe. Compressed air is input through the external air pipe, which can drive the button 44 to move along the axial direction of the mounting sleeve 43, thereby simulating a human hand pressing a button on the display board and achieving accurate testing of the button functions. It should be noted that when the pressing component drives the button testing component 4 to press down on the display board, the external air pipe of the mounting sleeve 43 is not connected. At this time, the lower end of the button 44 protrudes slightly from the bottom of the mounting sleeve 43 under the action of gravity. When the mounting sleeve 43 contacts the surface of the display board along with the pressure plate 41, the display board generates an upward reaction force on the button 44, forcing the button 44 to retract upward into the mounting sleeve 43 to avoid interference with the display board.
[0034] Furthermore, the button testing assembly 4 also includes a guide device 45 to ensure the stability and accuracy of the pressing action of the pressure plate 41. The guide device 45 includes a guide rod 46 disposed on the top plate 13 and a second guide sleeve 47 mounted on the pressure plate 41. The guide rod 46 passes through the second guide sleeve 47 and through the pressure plate 41. During the process of the pressing assembly 3 driving the pressure plate 41 to move up and down, the second guide sleeve 47 slides along the guide rod 46. The guide rod 46 provides a stable guiding effect for the pressure plate 41, so that the pressure plate 41 can always maintain a straight line movement and avoid deviation or shaking, thereby ensuring that the pressure plate 41 can accurately and smoothly press the display panel.
[0035] In addition, a second control switch 6 and an operation button 7 are also provided on the top plate 13. The second control switch 6 is connected to the air valve on the external air pipe via a wire and is used to control the opening or closing of the air valve. When the operator turns on the second control switch 6, the air valve circuit is turned on and enters the standby state. At this time, the air pipe passage is closed, waiting for further operation instructions. The operation button 7 is connected to the air valve control terminal. When the air valve is in standby, pressing the operation button 7 will send a signal. After receiving the signal, the air valve opens, and compressed air enters the mounting sleeve 43 of the button test component 4 through the air pipe, pushing the button 44 to press the display panel button and complete the button function test.
[0036] Furthermore, a visual judgment component 5 is also provided on the connecting plate 21 of the support frame 2. The visual judgment component 5 can analyze and judge parameters such as the image, color, and brightness displayed on the display board to determine whether the display board's display function is normal. The visual judgment component 5 includes a second mounting plate 50 and a detection camera 51. The second mounting plate 50 is fixedly mounted on the first mounting plate 30. The lens of the detection camera 51 is located directly above the test base 15. The detection camera 51 can slide along the height direction on the second mounting plate 50. Because the detection camera 51 is slidably mounted on the second mounting plate 50, the operator can flexibly adjust the position of the detection camera 51 according to the detection requirements of display boards of different sizes to ensure the accuracy of the detection. After the detection camera 51 completes the shooting, it will upload the acquired image to the management system in real time through the data transmission line. The management system will classify and store the data for subsequent traceability, query, and statistical analysis.
[0037] In addition, the top plate 13 is also equipped with status indicator lights 8 for intuitive feedback on the display board testing status. Status indicator lights 8 include three types: "OK", "NG", and "Testing". When the display board testing starts, the "Testing" status indicator light illuminates, indicating that the device is in operation; after the test is completed, if all functions of the display board pass the test, the "OK" status indicator light illuminates; if the display board has problems such as programming errors, abnormal button functions, or substandard display status, the "NG" status indicator light will illuminate.
