[0028] 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.
[0029] Reference Figures 1 to 4 As shown, a screen detection device of this utility model includes: a housing 1, the housing 1 including a detection space; a material carrier assembly 2, the material carrier assembly 2 including a first driving member 22 and a support plate 21, the first driving member 22 being connected to the housing 1, the support plate 21 being located in the detection space and rotatably connected to the housing 1, and the output end of the first driving member 22 being connected to the support plate 21; a carrier 3, at least two carriers 3 being connected to the support plate 21; a support assembly 4, a plurality of support assemblies 4 being connected to the housing 1, the support assembly 4 including a rolling member 44, the rolling member 44 abutting against the support plate 21; and a detection assembly 5, connected to the housing 1, the detection assembly 5 including a detection member 57, the detection end of the detection member 57 facing the support plate 21.
[0030] In this embodiment of the screen detection device, the screen to be tested is placed on a carrier 3. A first driving member 22 drives a support plate 21 to rotate. During the rotation of the support plate 21, a rolling member 44 abuts against the bottom of the support plate 21 and rolls until the screen to be tested moves to the detection position. At this time, the detection member 57 detects the screen to be tested. By supporting the support plate 21 with multiple support components 4, the support plate 21 is prevented from tilting when the screen to be tested is placed on the carrier 3 or removed from the carrier 3, thereby preventing the screen to be tested from tilting at the detection position and improving the detection accuracy. The rolling member 44 allows the rolling member 44 to roll during the rotation of the support plate 21, preventing vibration or damage to the support plate 21 caused by sliding friction between the support plate 21 and the support components 4, thereby further improving the detection accuracy.
[0031] Reference Figure 1 As shown, housing 1 includes a detection space located within housing 1, and the screen to be detected is detected within the detection space.
[0032] Reference Figure 2 , Figure 5 and Figure 6 As shown, the material loading assembly 2 includes a first driving member 22 and a support plate 21. The housing 1 includes a support plate 12. The first driving member 22 is connected to the support plate 12 of the housing 1. The support plate 21 is located in the detection space and is rotatably connected to the support plate 12 of the housing 1. Specifically, the support plate 21 is disc-shaped. The first driving member 22 is connected to the bottom side of the support plate 12, and the support plate 21 is rotatably connected to the top side of the support plate 12. The first driving member 22 is a rotary driving member, and its output end is connected to the middle position of the support plate 21, thereby enabling the first driving member 22 to drive the support plate 21 to rotate.
[0033] The carrier 3 is used to support the screen to be tested. At least two carriers 3 are connected to the top side of the support plate 21, and the at least two carriers 3 are centrally symmetrically distributed on the support plate 21 about its central axis. This makes the overall force on the support plate 21 more uniform and prevents the support plate 21 from tilting due to excessive force in some areas. In this embodiment, there are two carriers 3, and the center of the support plate 21 is located between the two carriers 3. Depending on the size of the support plate 21 and the carriers 3, the support plate 21 can be connected to different numbers of carriers 3.
[0034] The carrier 3 includes a material loading plate 31 located on the top side of the carrier 3. The material loading plate 31 has multiple locking blocks 32, each with a locking slot. The multiple locking blocks 32 form a material loading space. The multiple locking blocks 32 are arranged along the edge of the screen to be tested, with locking blocks 32 corresponding to the four corners of the screen and also corresponding to the middle of the long side of the screen. This allows the locking blocks 32 to support the screen to be tested and prevent it from bending. The edge of the screen to be tested can abut against the locking slot, thus fixing the position of the screen to be tested.
[0035] The carrier 3 also includes a first connecting plate 33 connected to the carrying plate 31. The first connecting plate 33 is parallel to and connected to the carrying plate 21. A first adjusting member 35 and a second adjusting member 36 are connected to the carrying plate 21. The first adjusting member 35 includes a connecting block connected to the carrying plate 21. The connecting block is threadedly connected to the adjusting block, which can be considered as a bolt. By rotating the adjusting block, the end of the adjusting block abuts against the edge of the first connecting plate 33, that is, the adjusting end of the first adjusting member 35 abuts against the edge of the first connecting plate 33. The second adjusting member 36 has the same structure as the first adjusting member 35, and will not be described again. The first connecting plate 33 and the carrying plate 21 can be connected by bolts through a slotted hole, so that the position of the first connecting plate 33 can be adjusted. The adjustment paths of the first adjusting member 35 and the second adjusting member 36 are perpendicular, that is, the adjusting ends of the first adjusting member 35 and the second adjusting member 36 abut against the two perpendicular edges of the first connecting plate 33, so that the position of the first connecting plate 33 in different directions can be adjusted by the first adjusting member 35 and the second adjusting member 36.
[0036] The carrier 3 also includes a second connecting plate 34 connected between the material carrier plate 31 and the first connecting plate 33, i.e., the two sides of the second connecting plate 34 are connected to the material carrier plate 31 and the first connecting plate 33 respectively. A third adjusting member 37 is connected to the first connecting plate 33. The third adjusting member 37 has the same structure as the first adjusting member 35 and will not be described again. The adjusting end of the third adjusting member 37 abuts against the edge of the second connecting plate 34. The second connecting plate 34 and the first connecting plate 33 are connected by bolts. The position of the second connecting plate 34 can be finely adjusted by the third adjusting member 37, and the second connecting plate 34 can also be kept stable. A spacer is also provided between the material carrier plate 31 and the second connecting plate 34. The two sides of the spacer are connected to the second connecting plate 34 and the material carrier plate 31 respectively. The spacer creates a space between the material carrier plate 31 and the second connecting plate 34 to accommodate electrical components. The electrical components are used to control the screen to be tested, thereby cooperating with the testing component 57 to complete the test. By setting the first adjusting member 35, the second adjusting member 36 and the third adjusting member 37, the position of the carrier plate 31 can be adjusted so that the screen to be tested can correspond to the position of the detection end of the detection member 57. At the same time, the setting of the adjusting members can also keep the carrier plate 31 stable.
[0037] Reference Figure 3 , Figure 4 and Figure 7 As shown, the support assembly 4 is used to support the carrier plate 21. Multiple support assemblies 4 are connected to the housing 1. The support assembly 4 includes a rolling element 44, which abuts against the carrier plate 21. Specifically, the support assembly 4 also includes a connecting seat 41 and a receiving member 43. The connecting seat 41 is connected to the support plate 12 of the housing 1. The receiving member 43 is used to receive the rolling element 44, which can be regarded as a ball bearing. The receiving member 43 is connected to the connecting seat 41 and includes a receiving cavity. The rolling element 44 is located in the receiving cavity. The top of the receiving member 43 has an opening. The opening is circular and the diameter of the opening is smaller than the diameter of the rolling element 44. The rolling element 44 abuts against the edge of the opening, and part of the rolling element 44 is located outside the receiving cavity, that is, part of the rolling element 44 protrudes from the opening into the receiving cavity and can abut against the bottom of the carrier plate 21. The assembly structure of the receiving member 43 and the rolling member 44 can be regarded as a steel ball roller. The top of the receiving member 43 is provided with an end cap, and the opening is located on the end cap. The end cap can be fixed by pressing, while the rolling member 44 is located in the receiving cavity. Multiple guide balls are rolled at the bottom of the receiving cavity. The guide balls can be regarded as small balls. The rolling member 44 abuts against the guide balls. The setting of the guide balls can avoid friction between the rolling member 44 and the side wall of the receiving member 43, thereby making the rotation of the support plate 21 more stable. In this embodiment, four support components 4 are equidistantly arranged along the moving path of the support plate 21. The four support components 4 are centrally symmetrical about the rotation axis of the support plate 21. Different numbers of support components 4 can be set according to different sizes of support plates 21.
[0038] The receiving member 43 has a connecting post 45 at the end away from the opening. The connecting post 45 has threads on its side wall, and the connecting seat 41 has a threaded hole at its end, so that the connecting post 45 and the connecting seat 41 are threadedly connected, thereby fixing the position of the receiving member 43. A washer 42 is provided between the ends of the receiving member 43 and the connecting seat 41. The washer 42 can be regarded as a spring washer 42, thereby improving the stability of the connection between the receiving post and the connecting seat 41.

The blocking assembly 6 includes a second driving member 66 and a baffle 65. The baffle 65 is connected to the output end of the second driving member 66. The baffle 65 can abut against the support plate 21 and can be located between the carriers 3. Specifically, the baffle 65 is perpendicular to the support plate 21, and the width of the baffle 65 is greater than the width of the carrier 3. The screen detection device also includes a first connecting frame connected to the housing 1. The first connecting frame includes a first connecting rod 15, a second connecting rod 16, and a support rod 13. The two support rods 13 are connected to the housing 1. The first connecting rod 15 and the second connecting rod 16 are both connected between the two support rods 13. The first connecting rod 15 is connected to the top side wall of the support rod 13. The second driving component 66 is a linear driving component. It is connected to the first connecting rod 15 via a third connecting plate 61. A mounting rod 62 is connected to the output end of the second driving component 66. A baffle 65 is connected to the mounting rod 62. A first limiting member 63, capable of abutting against the second connecting rod 16, is connected to the mounting rod 62. A second limiting member 64, capable of abutting against the mounting rod 62, is connected to the first connecting rod 15. Both the first limiting member 63 and the second limiting member 64 can be considered as buffers, thereby limiting the extreme movement position of the baffle 65. Two guide blocks 67 are also connected to the third connecting plate 61. A guide rod 68 is slidably connected to each guide block 67. The end of the guide rod 68 is connected to the mounting rod 62, and the guide rod 68 is parallel to the movement path of the baffle 65. The guide rod 68 and the guide blocks 67 guide the movement of the baffle 65, preventing it from shaking during movement.
[0040] Reference Figure 1 As shown, the housing is provided with a feed inlet 11, which corresponds to the position of part of the support plate 21. The screen to be tested can be placed on the carrier 3 through the feed inlet 11. The baffle 65 is located between the feed inlet 11 and the detection component 5. The baffle 65 is moved by the second driving member 66 so that the baffle 65 abuts against the support plate 21 and is located between the two carriers 3, thereby avoiding the light entering through the feed inlet 11 from affecting the detection of the detection component 57.
[0041] Reference Figure 10As shown, the detection component 5 is used to detect the screen to be tested, and the detection component 5 is connected to the housing 1. Specifically, the screen detection device also includes a second connecting frame 14 connected to the housing 1. The detection component 5 includes a mounting plate 51, a detection element 57, a third driving element 52, and a fourth driving element 53.

The movable base 59 is also connected to a guide column 55, and the movable frame 54 is connected to a guide plate 58. The guide plate 58 is slidably connected to the guide column 55, thereby guiding the movement of the detection element 57. The fourth driving component 53 can drive the detection element 57 to rise and fall. An angle adjusting component 56 is also connected between the detection element 57 and the movable frame 54. The angle adjusting component 56 can be regarded as an angle adjusting mechanism in the prior art, thereby adjusting the angle of the detection element 57.
[0042] In use, the screen to be tested is placed on carrier 3. The first drive member 22 drives the carrier plate 21 to rotate. During the rotation of the carrier plate 21, the rolling member 44 abuts against the bottom of the carrier plate 21 and rolls until the screen to be tested moves to the testing position. Then, the second drive member 66 drives the baffle 65 to abut against the carrier plate 21. At the same time, the third drive member 52 and the fourth drive member 53 cooperate to move the testing member 57 to the testing position. Another screen to be tested is placed on another carrier 3. After the testing member 57 has moved, it begins to test the screen to be tested. After the test is completed, the baffle 65 and the testing member 57 are reset, and the carrier plate 21 rotates, moving the screen that has been tested to the inlet 11. The screen to be tested moves to the testing position, and the above steps are repeated. During the testing of one screen to be tested, the screen that has been tested on another carrier 3 is removed and the screen to be tested is placed, thereby improving the testing efficiency.
[0043] This invention discloses a screen inspection device. Multiple support components 4 support a carrier plate 21, preventing the carrier plate 21 from tilting when the screen to be inspected is placed on or removed from the carrier 3. This prevents the screen from tilting at the inspection position, improving inspection accuracy. The rolling element 44 allows the carrier plate 21 to roll during rotation, preventing vibration or damage to the carrier plate 21 due to sliding friction between it and the support components 4, further improving inspection accuracy. By using multiple carriers 3, the device allows for the removal and placement of the inspected screen from another carrier 3 during the inspection process, improving inspection efficiency.
