[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 5As shown, a resistance testing device of this utility model includes: an adjustment component 1, which includes a first driving member 11, a second driving member 12, a third driving member 17, a rotary driving member 18, and a support plate 14. The second driving member 12 is connected to the output end of the first driving member 11, and the driving path of the second driving member 12 is perpendicular to that of the first driving member 11. The rotary driving member 18 is connected to the output end of the second driving member 12, and the output end of the rotary driving member 18 is connected to a mounting plate 15. The third driving member 17 is connected to the mounting plate 15, and the output end of the third driving member 17 is connected to a first movable seat 171. The first movable seat 171 is rotatably connected to a rolling member 172. The support plate 14... Plate 14 is slidably connected to mounting plate 15. A guide plate 144 is connected to the side of the support plate 14 near the mounting plate 15. The guide plate 144 includes a guide surface. The plane of the guide surface forms an acute angle with the plane of the support plate 14. The rolling element 172 abuts against the guide surface and can roll on the guide surface. The support plate 14 is provided with a plurality of first adsorption elements 141. Test assembly 2 includes a first detection element 28, a fourth driving element 23 and a test element 25. The test element 25 is connected to the output end of the fourth driving element 23. The test end of the test element 25 and the support plate 14 can both move towards the test position. The detection end of the first detection element 28 faces the test position.

[0029] In this embodiment of the resistance testing device, when testing a display screen, the display screen is placed on a support plate 14, and the first adsorption member 141 adsorbs the display screen. Then, the first driving member 11 and the second driving member 12 work together to move the display screen to below the test position. The third driving member 17 drives the first movable seat 171 to move, causing the rolling member 172 to move along the guide surface, thereby raising the support plate 14 to the height of the test position. Then, the first detection member 28 positions the connector of the display screen. By rotating the support plate 14 with the rotation driving member 18 and moving the support plate 14 with the first driving member 11 and the second driving member 12, the connector of the display screen is accurately positioned at the test position. Finally, the fourth driving member 23 drives the test member 25 to descend, and the test end of the test member 25 abuts against the connector of the display screen, thereby performing the test. The first driving member 11 and the second driving member 12 drive the support plate 14 to adjust horizontally, the rotation driving member 18 drives the support plate 14 to rotate, and the third driving member 17 drives the support plate 14 to adjust in height. Therefore, even if the installation position of the display screen connector is offset, the connector can be accurately positioned in the test position through multi-directional adjustment, ensuring that the connector of the display screen accurately abuts against the test end. Through the cooperation of the guide plate 144 and the rolling member 172, compared to using a lifting driving member, the height adjustment mechanism in the adjustment assembly 1 is smaller in size and has higher adjustment precision.

[0030] Reference Figure 1 As shown, the resistance testing device also includes a base plate 8, and the adjustment component 1, testing component 2, unloading component 3, loading component 5, first conveyor 4 and second conveyor 6 are all connected to the base plate 8.

Both the first driving member 11 and the second driving member 12 are linear driving members. The second driving member 12 is connected to the output end of the first driving member 11, and the driving path of the second driving member 12 is perpendicular to that of the first driving member 11. Specifically, the first driving member 11 is connected to the base plate 8, and the output end of the first driving member 11 is connected to a second movable seat 111. The second driving member 12 is connected to the second movable seat 111. A first slide rail 112 is provided on the base along the driving path of the first driving member 11.

The second movable seat 111 is connected to a second detection element 13 at one end near the test position. The second detection element 13 is connected to the controller and can be regarded as a visual inspection device. The second movable seat 111 is moved by the first driving element 11 so that the detection end of the second detection element 13 can face the test position. The second detection element 13 can perform position calibration on the movement of the display screen.

[0032] The rotary drive 18 is connected to the output end of the second drive 12. The second drive 12 is positioned perpendicular to the drive path of the first drive 11, allowing the first and second drive 11 to move the rotary drive 18 to multiple positions in the horizontal direction. The output end of the rotary drive 18 is connected to a mounting plate 15, and a third drive 17 is connected to the mounting plate 15. The rotary drive 18 can rotate the mounting plate 15, thereby causing the third drive 17 to rotate.

Specifically, guide sleeves 151 are connected to the four corners of the mounting plate 15, and guide posts 152 are slidably connected to the guide sleeves 151.

The top of the guide post 152 is connected to the support plate 14, and a stop is connected to the bottom of the guide post 152. The stop restricts the extreme movement of the guide post 152, thereby preventing the guide post 152 from detaching from the guide sleeves 151. Through the arrangement of the guide posts 152 and the guide sleeves 151, the lifting and lowering of the support plate 14 can be guided.

[0034] The third driving member 17 is a linear driving member. The output end of the third driving member 17 is connected to a first movable seat 171, which can drive the first movable seat 171 to move. The first movable seat 171 is rotatably connected to a rolling member 172, which can be considered a roller. The sidewall of the rolling roller protrudes from the top of the first movable seat 171. A guide plate 144 is connected to the side of the support plate 14 near the mounting plate 15. The width of the guide plate 144 gradually decreases along the driving path of the third driving member 17, thus forming an inclined guide surface at the bottom of the guide plate 144. The plane of the guide surface forms an acute angle with the plane of the support plate 14. The sidewall of the rolling member 172 abuts against the guide surface, and the third driving member 17 enables the rolling member 172 to roll on the guide surface, thereby controlling the lifting and lowering of the support plate 14. In this embodiment, two rolling members 172 and two guide plates 144 are provided, making the lifting and lowering of the support plate 14 more stable. The first movable seat 171 is slidably connected to the mounting plate 15. Specifically, the mounting plate 15 is connected to the second slide rail 173 along the drive path of the third drive member 17, and the first movable seat 171 is connected to the second slide rail 173.

[0035] The support plate 14 is equipped with multiple first adsorption elements 141 connected to an external vacuum source. The negative pressure generated by the first adsorption elements 141 adsorbs the display screen, fixing it relative to the support plate 14. The support plate 14 can then move the display screen. A pad 142 is also connected to the support plate 14, and multiple second adsorption elements 143 connected to the vacuum source are attached to the pad 142. The pad 142 supports the connector of the display screen, and the second adsorption elements 143 adsorb the connector, thus keeping the connector of the display screen fixed during testing. The pad 142 can be moved to the test position by the cooperation of the first driving element 11, the second driving element 12, the third driving element 17, and the rotary driving element 18, i.e., the connector of the display screen is located at the test position. Preferably, the mounting plate 15 is connected to multiple pressure measuring elements 16 connected to the first adsorption elements 141, and the support plate 14 is connected to multiple pressure measuring elements 16 connected to the second adsorption elements 143. The pressure measuring elements 16 can detect the adsorption pressure of the adsorption elements, thus keeping the display screen and its connector horizontal.

[0036] Reference Figure 5As shown, the test assembly 2 includes a first detection element 28, a fourth driving element 23, and a test element 25. The test element 25 is connected to the output end of the fourth driving element 23. Both the test end of the test element 25 and the support plate 14 can move towards the test position. The detection end of the first detection element 28 faces the test position. Specifically, the test assembly 2 also includes a first support frame 21, which is connected to the base plate 8. The first support frame 21 is connected to a first connecting plate 22 and a second connecting plate 29. The second connecting plate 29 is located on top of the first support frame 21 and is parallel to the base plate 8. The first connecting plate 22 is located between the test position and the second connecting plate 29 and is perpendicular to the base plate 8. The fourth driving component 23 is a linear driving component and is connected to the first connecting plate 22. The output end of the fourth driving component 23 is connected to the third movable seat 24. The test piece 25 is connected to the third movable seat 24, and the test end of the test piece 25 passes through the third movable seat 24. The test end of the test piece 25 is located above the test position. The fourth driving component 23 can drive the test end of the test piece 25 to descend, so that the test end of the test piece 25 moves to the test position. The second connecting plate 29 is connected to the mounting base 27. The first detection component 28 can be regarded as a visual inspection device and is connected to the controller. The first detection component 28 is connected to the mounting base 27. The test piece 25 is located between the first detection component 28 and the test position, that is, the first detection component 28 is located above the test piece 25. The first detection component 28 can guide and calibrate the movement of the display screen, so that the connector of the display screen can be accurately located in the inspection position. Preferably, the test component 2 includes multiple first detection elements 28 and test elements 25. In this embodiment, the test component 2 includes two first detection elements 28 and two test elements 25, so that it can be used to test different displays. A fifth driving element 26 is connected to the second connecting plate 29 along the length direction of the second connecting plate 29. The fifth driving element 26 is a linear driving element. The output end of the fifth driving element 26 is connected to one of the mounting bases 27, so that the fifth driving element 26 can drive the first detection elements 28 to move, so that the detection range of the first detection elements 28 is wider and it can be used to test different displays.

[0037] Reference Figure 6As shown, the resistance testing device also includes a feeding assembly 3, which includes a sixth driving member 31, a seventh driving member 34, and a first adsorption mechanism. The output end of the sixth driving member 31 is connected to the seventh driving member 34 via a connecting seat 33. The driving path of the sixth driving member 31 is perpendicular to the driving path of the seventh driving member 34. The first adsorption mechanism is connected to the output end of the seventh driving member 34. Both the first adsorption mechanism and the support plate 14 can move to the feeding position. Specifically, the feeding assembly 3 also includes a second support frame 32, which is connected to the base plate 8. The sixth driving member 31 is connected to the second support frame 32. Both the sixth driving member 31 and the seventh driving member 34 are linear driving members. The driving path of the sixth driving member 31 is perpendicular to the driving path of the seventh driving member 34. The sixth driving member 31 can drive the first adsorption mechanism to move horizontally, and the seventh driving member 34 can drive the first adsorption mechanism to rise and fall. Through the cooperation of the sixth driving member 31 and the seventh driving member 34, the first adsorption mechanism can move to the feeding position. Once the display screen passes the test, the carrier plate 14 can move to the unloading position, and the first adsorption mechanism moves the display screen located on the carrier plate 14 to the outside, thereby completing the unloading action.

[0038] Reference Figure 7 As shown, the first adsorption mechanism includes an adsorption plate 35, an adjusting plate 38, a fastener 37, and a third adsorption element 39. The adsorption plate 35 has multiple adjusting holes 36, which are oblong through holes. The fastener 37 can be considered a hand-tightening screw; its connecting part passes through the adjusting hole 36 and connects to the adjusting plate 38. The connecting part of the fastener 37 can move along the adjusting hole 36. The third adsorption element 39 is connected to a vacuum source and is also connected to the adjusting plate 38. When the third adsorption element 39 moves to a suitable position, the fastener 37 is tightened, thus fixing the position of the third adsorption element 39. The adsorption plate 35 is connected to multiple third adsorption elements 39, which can adsorb the display screen. The position of the third adsorption element 39 is adjustable, allowing the first adsorption mechanism to adsorb display screens of different sizes.

The second adsorption mechanism 52 is connected to the output end of the driving mechanism 51, and the driving mechanism 51 can drive the second adsorption mechanism 52 to move.

The second adsorption mechanism 52 can move towards the first conveyor 4 or the second conveyor 6. Specifically, the second adsorption mechanism 52 can drive the display screen to be tested located on the first conveyor 4 to the loading position via the drive mechanism 51. The second adsorption mechanism 52 can also drive the display screen that failed the test located at the loading position to the second conveyor 6 via the drive mechanism 51. When the support plate 14 is unloaded, the support plate 14 can also move to the loading position. At this time, the second adsorption mechanism 52 can place the display screen to be tested on the support plate 14.

[0040] Reference Figure 9 As shown, the resistance testing device also includes a detection component 7, which is located above a conveyor 4 and a second conveyor 6. The detection component 7 includes a third detection element 72 and a mounting bracket 71.

The third detection element 72 is used to assist the second adsorption mechanism 52 in accurately adsorbing and placing the display screen. A light source is connected to the bottom edge of the mounting bracket 71.

[0041] In use, the first conveyor 4 transports the display screen to be tested to one end near the loading assembly 5. Then, the second adsorption mechanism 52 drives the display screen to be tested, located on the first conveyor 4, to the loading position via the drive mechanism 51. Simultaneously, the unloaded support plate 14 moves to the loading position. The second adsorption mechanism 52 places the display screen to be tested on the support plate 14, and the first adsorption member 141 adsorbs the display screen. Further, the first drive member 11 and the second drive member 12 cooperate to move the display screen to below the test position. The third drive member 17 drives the first movable seat 171 to move, raising the support plate 14 to the height of the test position. Then, the first detection member 28 and the second detection member 13 cooperate to position the connector of the display screen to be tested. The rotating drive member 18 drives the support plate 14 to move. The plate 14 is rotated and adjusted, and the first driving member 11 and the second driving member 12 drive the support plate 14 to move and adjust, so that the connector of the display screen to be tested is accurately located in the test position; further, the fourth driving member 23 drives the test piece 25 to descend, and the test end of the test piece 25 abuts against the connector of the display screen to be tested, and the display screen to be tested is tested; when the display screen to be tested passes the test, the first adsorption mechanism and the support plate 14 both move to the unloading position, and the first adsorption mechanism moves the display screen that has passed the test located on the support plate 14 to the outside; when the display screen to be tested fails the test, the support plate 14 moves back to the loading position, and the second adsorption mechanism 52 drives the display screen that has failed the test located at the loading position to the second conveyor 6, and the second conveyor 6 moves the display screen that has failed the test to the outside.

[0042] This utility model discloses a resistance testing device. A first driving component 11 and a second driving component 12 adjust the horizontal position of a support plate 14, a rotation driving component 18 adjusts the rotation of the support plate 14, and a third driving component 17 adjusts the height of the support plate 14. This allows for multi-directional adjustment to ensure the connector is accurately positioned for testing even if the display screen connector's installation position is offset, ensuring precise contact between the connector and the test end.
