DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the drawings.

[0030] As Figure 1As shown, the embodiment of the application discloses a high-precision vehicle-mounted screen electric testing device, which comprises a feeding conveying line 1 and a discharging conveying line 2, one side of the feeding conveying line 1 and the discharging conveying line 2 is provided with an electric testing table 3 used for electric testing of products, a carrying frame 4 is arranged above the feeding conveying line 1 and the electric testing table 3, one side of the carrying frame 4 is provided with a first XYZ driving module 5, a fourth rotary motor 6 is arranged at the driving end of the first XYZ driving module 5, a first carrying assembly 7 is arranged at the driving end of the fourth rotary motor 6, the first carrying assembly 7 is used for carrying the product on the feeding conveying line 1 to the electric testing table 3, one side of the first carrying assembly 7 is provided with a first positioning camera 8 used for rough positioning of the product on the feeding conveying line 1, the other side of the carrying frame 4 is provided with a second XYZ driving module 9, a second carrying assembly 10 is arranged at the driving end of the second XYZ driving module 9, and the second carrying assembly 10 is used for carrying the product at the electric testing table 3 to the discharging conveying line 2. The electric testing table 3 comprises an electric testing assembly and an electric testing piece driving mechanism 301 used for driving the electric testing assembly to move horizontally, a second fine positioning camera 11 is arranged at the front end of the electric testing table 3, and a third fine positioning camera 12 is arranged at the middle part of the electric testing table 3. The first carrying assembly 7 places the product into the electric testing assembly after positioning and adjusting through the second fine positioning camera 11, and the electric testing assembly moves to the third fine positioning camera 12 to be positioned and adjusted again.

[0031] In specific work, the vehicle-mounted screen is moved from the previous device to the feeding conveying line 1, the first positioning camera 8 performs rough positioning on the vehicle-mounted screen to be tested, then the first carrying assembly 7 is driven by the first XYZ driving module 5 to suck the vehicle-mounted screen, and the vehicle-mounted screen is corrected in rotation according to the rough positioning result of the first positioning camera 8 through the fourth rotary motor 6, then the first carrying assembly 7 is driven by the first XYZ driving module 5 to carry the product above the second fine positioning camera 11, the second fine positioning camera 11 further positions the vehicle-mounted screen, the first XYZ driving module 5 and the fourth rotary motor correct the vehicle-mounted screen in rotation, and the corrected vehicle-mounted screen is placed into the electric testing assembly, the electric testing piece driving mechanism 301 drives the electric testing assembly to move to the third fine positioning camera 12, the electric testing assembly is finely adjusted in position according to the positioning structure of the third fine positioning camera 12, so that the FPC end of the vehicle-mounted screen can be perfectly pressed with the electric testing end of the electric testing assembly, and then stable electric testing operation is realized.

[0032] In the above structure, the first positioning camera 8 can realize coarse positioning of the vehicle-mounted screen, and the position of the vehicle-mounted screen is preliminarily adjusted. The second fine positioning camera 11 can further accurately adjust the position of the vehicle-mounted screen, so as to ensure that the vehicle-mounted screen can be accurately placed in the electrical measurement assembly. Since some precision loss may occur due to slight shaking during the process of placing the vehicle-mounted screen into the electrical measurement assembly, the third fine positioning camera 12 is arranged to realize repositioning of the product, so as to achieve final accurate testing. In actual production testing, the electrical measurement success rate can reach 99.5%.

[0033] In the embodiment, the electrical measurement assembly includes an electrical measurement mounting frame 302, and a product fixture 303 is mounted on the electrical measurement mounting frame 302. The product fixture 303 is provided with a UVW adjusting platform 305 and an electrical measurement crimping assembly mounted on the UVW adjusting platform 305 on one side.

[0034] Specifically, when the vehicle-mounted screen moves to below the third fine positioning camera 12, the third fine positioning camera 12 performs the last accurate positioning of the vehicle-mounted screen. After positioning is completed, the UVW adjusting platform 305 starts to work, and according to the data feedback of the third fine positioning camera 12, the electrical measurement crimping assembly is slightly adjusted in three dimensions, so as to ensure that the test pins on the electrical measurement crimping assembly can be accurately aligned with the test points of the FPC on the vehicle-mounted screen. After the UVW adjusting platform 305 completes the adjustment, the electrical measurement crimping assembly starts to work, and electrical performance testing is performed on the vehicle-mounted screen to be tested. During the testing process, the electrical measurement assembly collects and analyzes the test data to evaluate whether the performance of the vehicle-mounted screen meets the expected standard.

[0035] In the structure, the product fixture 303 needs to be frequently disassembled and replaced for electrical measurement of different vehicle-mounted screens. In the structure, the electrical measurement crimping assembly is adjusted to adapt to the position of the product. In this way, when the test product is replaced, only the fixture and the pressure head 308 in the electrical measurement crimping assembly need to be disassembled, and the UVW adjusting platform 305 does not need to be disassembled and adjusted.

[0036] Specifically, the electrical measurement crimping assembly can have various forms. The following are two specific structural forms: The first embodiment is that the electrical measurement crimping assembly includes a first bottom needle template 306 for bearing the FPC end of the product. The first bottom needle template 306 is provided with a pressure head mounting frame 307 above. The pressure head mounting frame 307 is provided with a pressure head 308 and a pressure head driving mechanism 309 for driving the pressure head 308 to move up and down. The UVW adjusting platform 305 is provided with a first driving air cylinder 310 for driving the pressure head mounting frame 307 to move horizontally.

[0037] It should be explained that when the detection product is replaced, the first bottom needle template 306 and the pressure head 308 should be replaced synchronously.

[0038] Specifically, when the test is performed, the vehicle screen is located in the product fixture 303, the FPC end of the vehicle screen is located on the first bottom needle template 306, the first driving cylinder 310 drives the pressure head mounting frame 307 to move above the first bottom needle template 306, so that the pressure head 308 can be accurately aligned with the FPC end of the vehicle screen. Subsequently, the pressure head driving mechanism 309 is started, driving the pressure head 308 to make lifting movement, lowering the pressure head 308 to contact the first bottom needle template 306, thereby crimping the FPC end of the vehicle screen. During the crimping process, the pressure head 308 and the test needle on the bottom needle template contact the FPC end of the vehicle screen to perform electrical performance test.

[0039] The second embodiment is that the electrical test and crimping assembly comprises a second bottom needle template 311 for bearing the FPC end of the product, one end of the second bottom needle template 311 is provided with a rotating upper pressure head 312, the rotating upper pressure head 312 is hinged with one end of the second bottom needle template, a spring is installed at the hinged end of the rotating upper pressure head 312 and the second bottom needle template, when there is no external force, the rotating upper pressure head 312 is in the state of springing up, one side of the rotating upper pressure head 312 is provided with a first pressing block 313 and a first rotating motor 314 for driving the first pressing block 313 to make rotating movement, when the first rotating motor 314 drives the first pressing block 313 to rotate, the first pressing block 313 drives the upper pressure head 308 to make rotating and pressing movement. The other end of the second bottom needle template 311 is provided with a pressing part 315, the bottom of the pressing part 315 is hinged with the second bottom needle template 311 through a spring, the upper part of the pressing part 315 comprises a pressing end and an opening end, when there is no external force, the pressing end applies pressure to the second bottom needle template 311, one side of the pressing part 315 is provided with a second pressing block 316 and a second driving cylinder 317 for driving the second pressing block 316 to make lifting movement, when the second pressing block 316 presses the opening end, the pressing end moves away from the second bottom needle template 311.

[0040] It should be explained that when the detection product is replaced, the second bottom needle template 311 and the rotating upper pressure head 312 should be replaced synchronously.

[0041] Specifically, when testing, the vehicle screen is located in the product fixture 303, and the FPC end of the vehicle screen is located on the second bottom needle template 311. At this time, the first rotary motor 314 is started to drive the first pressing block 313 to rotate, and the first pressing block 313 drives the rotary upper pressing head 312 to rotate and press, so that the rotary upper pressing head 312 is pressed to contact the second bottom needle template 311, thereby pressing and connecting one end of the FPC end of the vehicle screen. During the pressing process, the rotary upper pressing head 312 and the test needles on the second bottom needle template 311 contact the FPC end of the vehicle screen to test the electrical performance. When the test is completed, the second driving cylinder 317 is started to drive the second pressing block 316 to move up and down, and the second pressing block 316 presses the opening end of the pressing part 315, so that the pressing end moves away from the second bottom needle template 311. At this time, the rotary upper pressing head 312 is released and returns to the vertical state, so that the vehicle screen can be smoothly taken out.

[0042] The above two test structures can effectively press the FPC end of the vehicle screen to ensure the accuracy and stability of the electrical performance test. In actual application, appropriate test structures can be selected according to the specific size and shape of the vehicle screen and test requirements.

[0043] In the embodiment, the electrical measurement platform 3 includes two sets of electrical measurement assemblies and electrical measurement piece driving mechanisms 301 that drive the electrical measurement assemblies to move horizontally. The carrying frame 4 is provided at the bottom with a camera driving mechanism for driving the third precision positioning camera 12 to move reciprocally between the two sets of electrical measurement assemblies. The lens of the third precision positioning camera 12 is arranged downward, and the lens of the second precision positioning camera 11 is arranged upward.

[0044] Specifically, in the embodiment, two sets of electrical measurement assemblies and electrical measurement piece driving mechanisms 301 are arranged to simultaneously test two vehicle screens, thereby improving the test efficiency. The camera driving mechanism drives the third precision positioning camera 12 to move reciprocally between the two sets of electrical measurement assemblies, thereby ensuring that each vehicle screen can be accurately positioned before testing.

[0045] In the embodiment, the upper feeding transmission line 1 includes a first belt transmission line and a motor that drives the first belt transmission line to rotate. The tail end of the first belt transmission line is provided with a blocking plate 13.

[0046] Specifically, when the vehicle screen moves to the tail end of the first belt transmission line, the blocking plate 13 blocks the vehicle screen from moving forward. At this time, the first carrying assembly 7 carries the vehicle screen from the first belt transmission line to the electrical measurement platform 3 for testing.

[0047] In the structure, by setting the blocking plate 13, when the vehicle-mounted screen moves to the tail end of the first belt conveying line and the first conveying assembly 7 does not timely convey the vehicle-mounted screen, it can ensure that the screen does not fall off from the first belt conveying line.

[0048] In the embodiment, the first conveying assembly 7 and the second conveying assembly 10 each include a suction cup mounting frame 701, and a plurality of first suction nozzle units 702 are arranged on the suction cup mounting frame 701.

[0049] Specifically, a plurality of waist-shaped grooves can be arranged on the suction cup mounting frame 701, and the first suction nozzle units 702 are installed in the waist-shaped grooves through fasteners. The first suction nozzle units 702 can be adjusted according to the shape and size of different vehicle-mounted screens to ensure that the vehicle-mounted screens can be firmly adsorbed, so as to avoid slipping or damage during conveying.

[0050] In the embodiment, the tail end of the discharging conveying line 2 is provided with a double-layer conveying line 14, which includes an upper conveying line 141 for conveying unqualified products and a lower conveying line 142 for conveying qualified products.

[0051] Specifically, after the vehicle-mounted screen is tested, according to the test result, the vehicle-mounted screen will be transported to the upper conveying line 141 or the lower conveying line 142 of the double-layer conveying line 14. If the test result is unqualified, the vehicle-mounted screen will be transported to the upper conveying line 141 for subsequent maintenance or processing by the staff; if the test result is qualified, the vehicle-mounted screen will be transported to the lower conveying line 142 for subsequent packaging or warehousing operations.

[0052] The double-layer conveying line 14 can realize automatic diversion of unqualified products and qualified products, and improve the automation degree and efficiency of the production line.

[0053] In the embodiment, the discharging conveying line 2 includes a second belt conveying line and a motor for driving the second belt conveying line to rotate, and the bottom of the discharging conveying line 2 is provided with a third driving cylinder 201 for driving the discharging conveying line 2 to move up and down, so that the second belt conveying line can move to the upper conveying line 141 and the lower conveying line 142, respectively.

[0054] Specifically, when the discharging operation of the vehicle-mounted screen is needed, if the vehicle-mounted screen is a good product, the third driving cylinder 201 is started to drive the discharging conveying line 2 to move up and down, so that the second belt conveying line transports the vehicle-mounted screen to the corresponding lower conveying line 142. If the vehicle-mounted screen is a defective product, the third driving cylinder 201 is started to drive the discharging conveying line 2 to move up and down, so that the second belt conveying line transports the vehicle-mounted screen to the corresponding lower conveying line 142.

[0055] The above arrangement can ensure that the vehicle-mounted screen can be accurately delivered to the designated position after the test is completed, facilitating subsequent processing and analysis.

[0056] In this embodiment, the tail end of the lower layer transmission line 142 is provided with a turnover mechanism 143, which includes a turnover frame 1431, and a turnover assembly is arranged on the turnover frame 1431. The turnover assembly includes a turnover mounting frame 1432, a rotating rod 1433 and a third rotary motor 1434 for driving the rotating rod 1433 to rotate are arranged on the turnover mounting frame 1432, and a suction cup mounting plate 1435 is further included, a plurality of second suction nozzle units 1436 are arranged on the suction cup mounting plate 1435, and one end of the suction cup mounting plate 1435 is connected with the rotating rod 1433.

[0057] Specifically, when the detected product needs to be turned over and dispensed, the third rotary motor 1434 is started to drive the rotating rod 1433 to rotate, thereby driving the suction cup mounting plate 1435 and the second suction nozzle unit 1436 to turn over. At this time, the second suction nozzle unit 1436 will adsorb the vehicle-mounted screen that has completed the test, and the vehicle-mounted screen will be turned over to a specified angle with the turning action of the turnover assembly. After the turning is completed, subsequent dispensing and discharging operations are performed through the next station.

[0058] The above structure makes the high-precision vehicle-mounted screen electrical test equipment flexible to adapt to different test requirements, improving the multifunctionality and operation convenience of the equipment.

[0059] In this embodiment, the turnover mounting frame 1432 is vertically and slidingly connected with the turnover frame 1431, and a fourth drive cylinder 1437 for driving the turnover mounting frame 1432 to move up and down is arranged at the bottom of the turnover mounting frame 1432.

[0060] Specifically, the fourth drive cylinder 1437 can increase the turning radius of the turnover frame 1431, that is, the second suction nozzle unit 1436 can move to a farther distance, thereby meeting the turning requirements of different vehicle-mounted screens. When the size of the vehicle-mounted screen to be turned over is large or the turning angle is large, the fourth drive cylinder 1437 is started to drive the turnover mounting frame 1432 to move up, thereby driving the turnover assembly and the second suction nozzle unit 1436 to move up to adjust the starting position of the turning, so that the turning action is more smooth and can be accurately completed. Such design not only improves the flexibility and application range of the equipment, but also ensures the stability and accuracy of the turning operation.

[0061] In the embodiment, the turnover frame 1431 is provided with a gap for the product to pass through, and further comprises a detachable baffle 1438 installed on one side of the turnover frame 1431, which is used to shield the gap.

[0062] Specifically, when the lower transmission line 142 needs to be directly connected with the transmission line of the next station, the detachable baffle 1438 can be removed, so that the vehicle-mounted screen can pass through the gap and move to the next station smoothly. If the vehicle-mounted screen needs to be turned over, the detachable baffle 1438 can be installed, so that the detachable baffle 1438 can block the vehicle-mounted screen, and the turnover assembly can suck and turn over the vehicle-mounted screen smoothly, preventing the vehicle-mounted screen from flowing into the next station.

[0063] The above specific embodiments further illustrate the purpose, technical solutions and advantages of the present application. It should be understood that the above description is only specific embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
