Description

Technical Field

[0001] This application relates to the field of display screen testing technology, and in particular to a comprehensive electrical performance testing device for home appliance displays. Background Technology

[0002] With the rapid popularization of smart homes and home appliances, LCD and OLED displays have become core interactive components in air conditioners, refrigerators, kitchen appliances, and small appliances, and their electrical performance directly determines the overall functionality and safety of the appliance. In the mass production and factory testing of home appliance displays, comprehensive electrical performance testing is a key process for quality control, requiring rapid completion of power supply connection, signal loading, parameter acquisition, and pass / fail determination.

[0003] The existing technology still has the following problems:

[0004] 1. Existing testing equipment does not have a double clamping structure designed for home appliance displays. During testing, the screen is prone to slippage, leading to test point misalignment and poor contact. Moreover, it is not easy to detect when the screen shifts, affecting test accuracy and the reliability of results. In addition, existing connectors rely solely on the friction of their own springs for fixation, without additional locking and limiting structures. This results in weak anti-interference capabilities, and the wires are easily loosened under external force, directly causing test interruptions and data distortion, seriously affecting the continuity of testing and the accuracy of data.

[0005] 2. Existing testing equipment cannot clean the outer surface of the display screen. During the production, transportation and loading process of home appliance display screens, dust, oil, fingerprints and debris inevitably adhere to the surface. These contaminants will interfere with the optical detection and visual positioning functions of the equipment, causing recognition errors. At the same time, hard foreign objects on the screen surface can easily scratch the panel, forming permanent damage such as scratches and indentations. This not only damages the appearance quality of the product, but also causes the product to be scrapped, significantly reducing the overall yield. Summary of the Invention

[0006] To overcome the shortcomings of existing testing devices that lack a dual-clamping structure specifically designed for home appliance displays, which leads to screen slippage during testing, resulting in test point misalignment, poor contact, and difficulty in detecting screen misalignment, thus affecting test accuracy and reliability, and to address the fact that current connectors rely solely on their own spring friction for fixation without additional locking and limiting structures, resulting in weak anti-interference capabilities and easy loosening of wires under external force, directly causing test interruptions and data distortion, severely impacting the continuity and accuracy of testing, and that the testing device cannot clean the outer surface of the display, while home appliance displays inevitably accumulate dust, oil, fingerprints, and debris during production, transportation, and loading processes, which can interfere with the optical detection and visual positioning functions of the equipment, causing recognition errors, and that hard foreign objects on the screen surface can easily scratch the panel, causing permanent damage such as scratches and indentations, the purpose of this invention is to provide a comprehensive electrical performance testing device for home appliance displays to solve the above-mentioned deficiencies.

[0017] The technical solution provided in this application has at least the following technical effects or advantages:

[0018] 1. By employing a connecting component, this invention effectively solves the problem of existing testing devices lacking a dual-clamping structure designed for home appliance displays. This leads to screen slippage during testing, causing test point misalignment and poor contact, which is difficult to detect, affecting test accuracy and result reliability. Furthermore, existing connectors rely solely on their own spring friction for fixation, lacking additional locking and limiting structures, resulting in weak anti-interference capabilities. Wires are easily detached under external force, directly causing test interruptions and data distortion, severely impacting the continuity and accuracy of testing. This invention, through its connecting component, provides dual clamping during testing of home appliance displays, effectively preventing screen slippage and eliminating test point misalignment and poor probe contact. Screen misalignment can be detected promptly, significantly improving test accuracy and result reliability. Simultaneously, the addition of a locking and limiting structure to the connector provides buffering and anti-detachment effects under external force interference, significantly enhancing the connector's resistance to external forces and effectively preventing detachment. This prevents test interruptions and data distortion, ensuring the continuity and accuracy of testing.

[0019] 2. By employing a cleaning component, this invention effectively solves the problem of existing testing devices being unable to clean the outer surface of the display screen. During the production, transportation, and loading processes of home appliance displays, dust, oil, fingerprints, and debris inevitably accumulate on the surface. These contaminants interfere with the optical detection and visual positioning functions of the equipment, causing recognition errors. Furthermore, hard foreign objects on the screen surface can easily scratch the panel, causing permanent damage such as scratches and indentations. This not only damages the product's appearance but also leads to product scrap, significantly reducing the overall yield. This invention, through its cleaning component, can effectively clean the display screen surface before testing, thoroughly removing dust, oil, fingerprints, and debris. This eliminates the interference of contaminants on optical detection and visual positioning, avoids recognition errors, ensures a smooth testing process and accurate judgment, and prevents hard foreign objects from scratching the screen, preventing appearance defects such as scratches and indentations, reducing product scrap, eliminating manual cleaning procedures, and improving overall testing efficiency.

[0034] To address the issue of screen slippage during testing, which can lead to test point misalignment and poor contact, this invention utilizes a connecting component to provide double clamping during testing of the home appliance display screen. This effectively prevents screen slippage during testing and eliminates test point misalignment and probe contact issues. Furthermore, to address the problem of not being able to clean the outer surface of the display screen, this invention employs a cleaning component to effectively clean the screen surface before testing, thoroughly removing dust, oil, fingerprints, and debris. This eliminates interference from contaminants on optical detection and visual positioning, preventing recognition errors.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1:

[0036] Please see Figure 1As shown, a comprehensive electrical performance testing device for a home appliance display screen includes a main testing device 1, a turntable 2, a display screen 4, a plug 5, and connecting wires 6. The top of the turntable 2 is used to connect to an external power supply. A probe is installed on the top of the main testing device 1 for comprehensive electrical performance testing of the display screen 4. One end of the connecting wire 6 is connected to the top of the turntable 2. The display screen 4 and the plug 5 are fixedly connected. A drive motor is installed inside the main testing device 1, and the output end of the drive motor is sleeved with the bottom end of the turntable 2. The turntable 2 is rotatably connected to the inner cavity of the main testing device 1. A connecting component 3 is installed on the upper surface of the turntable 2. The outer surface of the test equipment is equipped with a display screen 4, and a slot is provided on the outer surface of the display screen 4. The plug 5 is inserted into the slot. The outer surface of the test equipment body 1 is provided with a cleaning component 7. During the test, the display screen 4 is placed on the connecting component 3 for clamping and fixing. The cleaning component 7 cleans the outer surface of the display screen 4 to prevent dust on the outer surface of the display screen 4 from interfering with the test. The connecting component 3 is used to limit the plug 5, so that the plug 5 and the display screen 4 maintain stable contact, thereby preventing external force from dragging the connecting wire 6, causing the plug 5 to fall out of the slot of the display screen 4, which would cause the test to be interrupted and the test data to be distorted.

[0037] Please see Figure 1 and Figure 2 As shown, the connecting assembly 3 includes a support plate 31, with a first threaded rod 32 rotatably connected to the inner cavity of the support plate 31. Clamping mechanisms 33 are provided at both ends of the support plate 31, and a first connecting plate 34 is fixedly installed on one side of the support plate 31. A buffer mechanism 35 and a locking and limiting mechanism 36 are provided on the outer surface of the first connecting plate 34. The support plate 31 and the turntable 2 are fixedly connected. When testing the display screen 4, the display screen 4 is placed on the support plate 31, and the clamping mechanism 33 clamps and fixes the display screen 4 by rotating the first threaded rod 32. The slot of the display screen 4 and the plug 5 are inserted. The buffer mechanism 35 and the locking and limiting mechanism 36 on the first connecting plate 34 are used to limit and buffer the connection of the wire 6, preventing the plug 5 from falling out of the slot due to external force, thereby ensuring the stability of the connection between the plug 5 and the display screen 4 during the test. At this time, the turntable 2 rotates 90 degrees on the main body 1 of the testing equipment, so that the display screen 4 moves to the bottom of the cleaning assembly 7 for cleaning.

[0038] Please see Figure 2 , Figure 3 and Figure 4As shown, the clamping mechanism 33 includes a clamping plate 331. A first slider 332 is slidably connected to the inner cavity of the clamping plate 331. Slide rods 333 are fixedly installed at both ends of the first slider 332. A first spring 334 is sleeved on the outer surface of the slide rods 333. Flexible clamping blocks 335 are slidably connected to both ends of the first slider 332. A connecting strip 336 is fixedly connected to the outer surface of the flexible clamping blocks 335. A spring rod 337 is fixedly installed on the outer surface of the first slider 332. A second spring 338 is sleeved on the outer surface of the spring rod 337. A first button 339 is provided in the middle part of the clamping plate 331. A first alarm 3310 is fixedly installed on the outer surface of the clamping plate 331. The clamping plate 331 and the support plate 31 are slidably connected. The slide bar 333 and the clamping plate 331 are slidably connected. The first slide bar 332 and the clamping plate 331 are connected by threads, and the threads at both ends of the first slide bar 332 are opposite in direction. The first slide bar 333 and the clamping plate 331 are slidably connected. The first spring 334 is located between the inner wall of the first slide bar 332 and the clamping plate 331. The two ends of the first button 339 are chamfered, and the middle bottom wall of the first slide bar 332 is rounded. In this way, the first slide bar 332 can press the first button 339 when it moves. The first button 339 and the first alarm 3310 are electrically connected, and the pressing of the first button 339 controls the first alarm 3310 to sound an alarm. The connecting bar 336 and the elastic rod 337 are slidably connected. The second spring 338 is located between the elastic rod 337 and the connecting bar 336. The flexible clamping block 335 is located at... Now, on the outside of the clamping plate 331, when clamping the display screen 4, the first threaded rod 32 is rotated to drive the clamping plate 331 to slide on the support plate 31, so that the two clamping plates 331 move closer to each other. At this time, the flexible clamping block 335 first contacts the side of the display screen 4. As the clamping plates 331 continue to move closer, the flexible clamping block 335 slides in the inner cavity of the first slider 332, causing the connecting bar 336 to slide on the elastic rod 337 and compress the second spring 338 until the outer surface of the clamping plate 331 contacts the side of the display screen 4. At this time, the clamping plate 331 and the flexible clamping block 335 clamp the display screen 4 to limit its position. The elastic force of the second spring 338 keeps the flexible clamping block 335 and the display screen 4 in close contact, preventing the display screen 4 from being moved. During the test, slippage or displacement occurs, preventing test point misalignment, poor probe contact, etc. When the display screen 4 shifts within the cavity of the clamping plate 331, the movement of the display screen 4 causes the flexible clamping block 335 to move. The movement of the flexible clamping block 335 causes the first slider 332 to slide within the cavity of the clamping plate 331. The sliding of the first slider 332 causes the sliding rod 333 to slide within the cavity of the clamping plate 331 and compress the first spring 334. At this time, the first slider 332 presses the first button 339, causing the first alarm 3310 to sound an alarm, reminding the staff that the display screen 4 has shifted during the test, making it easier for the staff to detect in time, thereby greatly improving the test accuracy and the reliability of the test results.

[0039] Please see Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the buffer mechanism 35 includes a limiting ring 351, which is fixedly connected to the first connecting plate 34. A groove 352 is formed on the outer surface of the limiting ring 351. A buffer ring 353 is provided in the middle of the limiting ring 351. A buffer rod 354 is fixedly installed on the outer surface of the buffer ring 353. A third spring 355 is sleeved on the outer surface of the buffer rod 354. A washer 356 is slidably connected to the outer surface of the third spring 355. The connecting wire 6 is slidably connected to the buffer ring 353. The third spring 355 is located between the buffer ring 353 and the washer 356. The washer 356 is slidably connected to the inner wall of the limiting ring 351. The washer 356 is used to prevent the third spring 355 and the limiting ring 351 from rubbing against each other. The locking and limiting mechanism 36 includes a fixed... A fixed block 361 is slidably connected to an elastic block 362 within its inner cavity. A first connecting rod 363 is fixedly installed on the inner wall of the fixed block 361. A fourth spring 364 is sleeved on the outer surface of the first connecting rod 363. A connecting frame 365 is fixedly installed on the outer surface of the fixed block 361. A second button 366 is provided on the inner wall of the connecting frame 365. A second alarm 367 is fixedly installed on the outer surface of the connecting frame 365. A limit block 368 is slidably connected to the inner cavity of the connecting frame 365. A second connecting rod 369 is fixedly installed on the inner wall of the connecting frame 365. A fifth spring 3610 is sleeved on the outer surface of the second connecting rod 369. A first protrusion 3611 is fixedly installed at one end of the limit block 368. The outer surface of the limit block 368 is fixed... A first compression rod 3612 is installed, a fixed block 361 and a first connecting plate 34 are fixedly connected, and the inner cavity of the top of the elastic block 362 is fixedly connected to the connecting wire 6. When the plug 5 and the slot on the outer surface of the display screen 4 are inserted, the connecting wire 6 between the elastic block 362 and the plug 5 has a bent part. Thus, when the connecting wire 6 is dragged, the locking limit mechanism 36 can prevent the tension of the connecting wire 6 from affecting the plug 5, thereby maintaining a stable connection between the plug 5 and the display screen 4. The fourth spring 364 is located between the inner wall of the elastic block 362 and the fixed block 361. The second button 366 and the second alarm 367 are electrically connected, and pressing the second button 366 controls the second alarm 367 to sound an alarm. The top of 62 is located between the limiting block 368 and the first protrusion 3611. The second connecting rod 369 is located between the limiting block 368 and the inner wall of the connecting frame 365. When the limiting block 368 slides towards the second connecting rod 369, the first pressing rod 3612 presses the second button 366. The two ends of the second button 366 are chamfered. When the connecting wire 6 is dragged, the lateral tension of the connecting wire 6 presses the buffer ring 353, causing the buffer ring 353 to shift within the inner cavity of the limiting ring 351. At this time, the buffer rod 354 slides within the inner cavity of the groove 352 and presses the third spring 355. Thus, the buffer ring 353 can buffer the connecting wire 6 laterally, preventing the connecting wire 6 from having a large swaying amplitude.Simultaneously, the tension of the connecting wire 6 causes the elastic block 362 to slide on the fixed block 361 and the first connecting rod 363, compressing the fourth spring 364. The elastic force of the fourth spring 364 is used to buffer the tension of the connecting wire 6. When a large tension is applied to the connecting wire 6, the elastic block 362 continues to slide on the fixed block 361. As the elastic block 362 moves, the top of the elastic block 362 compresses the first protrusion 3611 in the inner cavity of the connecting frame 365, causing the limiting block 368 to slide on the connecting frame 365 and the second connecting rod 369, compressing the fifth spring 3610. The elastic force of the fifth spring 3610 is used to buffer the tension of the connecting wire 6 a second time, ultimately locking the connecting wire 6. At the same time, the movement of the limiting block 368 causes the first compression rod 3612 to press against the second button 36. The compression generated by wire 6 triggers the second alarm 367, ensuring that the tension on the connecting wire 6 does not affect the insertion of the plug 5 and the display screen 4. Combined with the clamping mechanism 33 limiting the position of the display screen 4, it allows for simultaneous monitoring of both the display screen 4 and the plug 5, preventing movement between them. This effectively avoids screen slippage during testing, eliminating test point misalignment and poor probe contact. When the display screen 4 shifts, it can be detected promptly, significantly improving test accuracy and the reliability of the test results. Simultaneously, the plug 5 is equipped with a locking and limiting structure, providing buffering and anti-detachment effects when the connecting wire 6 is subjected to external force interference, significantly enhancing the plug 5's resistance to external forces and effectively preventing loosening. This prevents test interruptions and data distortion, ensuring the continuity and accuracy of the testing work. Example 2:

[0040] Please see Figure 10 and Figure 11 As shown, the cleaning component 7 includes a support leg 71, a lifting mechanism 72 at the top of the support leg 71, a connecting block 73 on the upper surface of the lifting mechanism 72, and a dust removal frame 74 fixedly mounted on the lower surface of the connecting block 73. A gear 75 is rotatably connected to the middle part of the dust removal frame 74, and half of the gear 75 is hollowed out, so that when the gear 75 rotates, it can drive a gear frame 76 to reciprocate within the cavity of the dust removal frame 74. The gear frame 76 is slidably connected to the cavity of the dust removal frame 74, and a cleaning mechanism 77 is provided on the outer surface of the gear frame 76. An electric motor 78 is installed on the upper surface. The output end of the electric motor 78 is sleeved with a gear 75. The gear 75 meshes with a gear frame 76. The support leg 71 is fixedly connected to the outer surface of the main body 1 of the test equipment. The height of the connecting block 73 is adjusted by the lifting mechanism 72 so that the cleaning mechanism 77 can contact the outer surface of the display screen 4. The operation of the electric motor 78 drives the gear 75 to rotate. The rotation of the gear 75 drives the gear frame 76 to move back and forth in the inner cavity of the dust removal frame 74. The movement of the gear frame 76 drives the cleaning mechanism 77 to wipe and clean the outer surface of the display screen 4.

[0041] Please see Figure 10 , Figure 12 and Figure 13As shown, the lifting mechanism 72 includes an adjusting block 721. A second threaded rod 722 is rotatably connected to the inner cavity of the adjusting block 721. A driving block 723 is slidably connected to the upper surface of the adjusting block 721.

The second connecting plate 771 is slidably connected, the second pressing rod 774 is slidably connected to the second connecting plate 771, the sixth spring 776 is located between the inner walls of the second slider 773 and the second connecting plate 771, the bottom end of the cleaning brush 772 is provided with bristles, when the toothed frame 76 moves, the rolling ball 775 and the second protrusion 778 contact and generate compression, the bristles at the bottom end of the cleaning brush 772 contact the outer surface of the display screen 4, by rotating the second threaded rod 722, the driving block 723 is driven to slide on the upper surface of the adjusting block 721, so that the driving rod 724 slides in the inner cavity of the driving groove 728, at this time the lifting rod 726 slides in the inner cavity of the receiving rod 725, and at the same time the distance between the lifting plate 727 and the adjusting block 721 changes, so that the height of the connecting block 73 changes, thus enabling The contact pressure between the bristles on the lower surface of the cleaning brush 772 and the screen 4 is adjustable to avoid damage to the screen 4 while still cleaning its outer surface. The movement of the toothed frame 76 moves the second connecting plate 771, which in turn causes the ball 775 and the second protrusion 778 on the fixed plate 777 to press against each other. This causes the second slider 773 and the second pressing rod 774 to slide within the inner cavity of the second connecting plate 771. The sliding of the second slider 773 moves the cleaning brush 772. This, combined with the reciprocating movement of the toothed frame 76, allows the bristles to perform cross-cleaning of the screen 4. Bidirectional cross-cleaning can fully cover the dead corners of the outer surface of the screen 4, while lateral cleaning can remove floating dust and residual impurities from the outer surface of the screen 4.Vertical cleaning compensates for the blind spots of horizontal cleaning, thoroughly removing dust, oil, fingerprints, and debris, thereby eliminating interference from contaminants on optical detection and visual positioning, avoiding recognition errors, ensuring a smooth testing process and accurate judgment. Simultaneously, it prevents hard foreign objects from scratching the screen, preventing scratches, dents, and other cosmetic defects, reducing product scrap, eliminating manual cleaning steps, and improving overall testing efficiency.

[0042] In summary, during testing, the display screen 4 is placed on the connecting component 3 for clamping and fixing. The cleaning component 7 cleans the outer surface of the display screen 4 to prevent dust from interfering with the test. The connecting component 3 limits the plug 5, ensuring stable contact between the plug 5 and the display screen 4, thus preventing external forces from dragging the connecting wire 6 and causing the plug 5 to fall out of the slot of the display screen 4, which would interrupt the test and distort the test data. When testing the display screen 4, it is placed on the support plate 31, and the clamping mechanism 33 clamps and fixes the display screen 4 by rotating the first threaded rod 32. The slot of the display screen 4 and the plug 5 are inserted, and the first connecting plate 34... The buffer mechanism 35 and locking limit mechanism 36 on the upper part are used to limit and buffer the connection wire 6 to prevent the plug 5 from falling out of the slot due to external force dragging, thereby ensuring the stability of the connection between the plug 5 and the display screen 4 during the test. At this time, the turntable 2 rotates 90 degrees on the main body 1 of the test equipment, so that the display screen 4 moves to the bottom of the cleaning component 7 for cleaning. The height of the connecting block 73 is adjusted by the lifting mechanism 72 so that the cleaning mechanism 77 can contact the outer surface of the display screen 4. The operation of the motor 78 drives the gear 75 to rotate. The rotation of the gear 75 drives the gear frame 76 to move back and forth in the inner cavity of the dust removal frame 74. The movement of the gear frame 76 drives the cleaning mechanism 77 to wipe and clean the outer surface of the display screen 4.
