[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] like Figure 1 and 5 As shown, a high-generation TFT-LCD glass substrate surface visual light inspection equipment comprises a base 1, a light inspection box 5 is arranged above the base 1, a tilting mechanism 2 is arranged on the top surface of the base 1, a mounting plate 3 which can be tilted and displaced therewith is horizontally mounted on the tilting mechanism 2, the light inspection box 5 is detachably arranged on the top surface of the mounting plate 3, and a clamping mechanism 7 for positioning the TFT-LCD glass substrate is arranged on the front of the light inspection box 5.

[0027] By adopting the above technical solution, the tilting mechanism 2 provided on the device drives the mounting plate 3 mounted thereon to tilt and displace accordingly. The lamp inspection box 5 is arranged on the top surface of the mounting plate 3 and will also tilt at the same angle as the mounting plate 3. In this way, the tilting angle can be reasonably adjusted according to the actual observation needs of different people, effectively improving the observation effect. At the same time, a clamping mechanism 7 for positioning the TFT-LCD glass substrate is provided on the front surface of the lamp inspection box 5, which can ensure that the TFT-LCD glass substrate will not fall off the lamp inspection box 5 during the tilting process, causing unnecessary losses.

[0028] As Figure 1 shown, the tilting mechanism 2 includes guide support plates 21 with a semi-circular structure. The two guide support plates 21 are longitudinally symmetrically arranged at the end parts of the top surface of the base 1 respectively; the bottom end parts of the mounting plate 3 are integrally and vertically symmetrically connected with support plates 31. The support plates 31 are circumferentially slidably connected with the top surfaces of the corresponding guide support plates 21 through the arc-shaped surfaces provided on their bottom surfaces; a driving component 22 for driving the mounting plate 3 to tilt and displace along the guide support plates 21 is arranged in the middle of the top surface of the base 1.

[0029] By adopting the above technical solution, the two guide support plates 21 with a semi-circular structure are circumferentially slidably connected with the arc-shaped surfaces on the bottom surfaces of the support plates 31. In this way, it can not only ensure more stable tilting, but also reduce the bearing capacity of the driving component 22, make its operation smoother, and improve its service life.

[0030] As Figure 2 shown, the driving component 22 includes an arc-shaped tooth track 224 longitudinally arranged in the middle of the top surface of the base 1. The two guide support plates 21 are vertically bridged by a strengthening column 23 horizontally arranged on the top surface of the base 1. The arc-shaped tooth track 224 is radially mounted in the middle of the strengthening column 23; a spiral tooth rod 222 is meshed with the arc-shaped tooth track 224. One end of the spiral tooth rod 222 is axially rotatably connected with a bearing seat 221, and the outer diameter of the bearing seat 221 is larger than the outer diameter of the spiral tooth rod 222. The bearing seat 221 is radially fixedly clamped with an arc-shaped groove 32 horizontally penetrating through the middle of the bottom surface of the mounting plate 3; one end of the spiral tooth rod 222 passes through the corresponding bearing seat 221 and is bearing-connected with a rotating rod 223. A handle 2231 is arranged at the outer end of the rotating rod 223 extending out of the arc-shaped groove 32.

[0031] By adopting the above technical solution, manually rotating the handle 2231 drives the rotating rod 223 to rotate around the bearing seat 221. The rotating rod 223 synchronously drives the spiral rack 222 to travel along the arc-shaped tooth track 224, thereby driving the mounting plate 3 to tilt and displace along the guiding support plate 21. The entire driving assembly 22 adopts a gear transmission structure, making the tilting angle easily controlled manually and the operation very convenient. The provided strengthening column 23 can not only ensure the coaxiality of the two guiding support plates 21 and the arc-shaped tooth track 224, making the tilting more stable, but also increase the support stability of the entire tilting mechanism 2.

[0032] As Figure 1 , 3 and shown in FIG. 4, the outer end surface of the guiding support plate 21 is recessed inwardly with a travel groove 211 having the same shape as it. The top surface of the travel groove 211 is penetrated and provided with a limit groove 212 having an arc-shaped structure. A locking assembly 4 is radially inserted into the limit groove 212. The locking assembly 4 includes a limit screw 41, which is radially inserted into the limit groove 212 with a clearance. The top end of the limit screw 41 is radially fixedly connected to the middle of the arc-shaped surface of the corresponding support plate 31. A spacer 42 is axially inserted through the lower part of the limit screw 41. The spacer 42 is in contact with the inner top surface of the travel groove 211 through the arc-shaped surface provided on its top surface. A locking nut 43 is axially screwed to the bottom of the limit screw 41.

[0033] By adopting the above technical solution, during tilting, the locking nut 43 can be loosened, so that the spacer 42 is not in contact with the inner top surface of the travel groove 211, thus preventing the support plate 31 from separating from the guiding support plate 21 during the tilting process. When the tilting stops, the locking nut 43 can be tightened, so that the spacer 42 is tightly attached to the inner top surface of the travel groove 211, effectively increasing the positioning effect between the support plate 31 and the guiding support plate 21 and achieving the purpose of fixing the tilting angle.

[0034] As Figure 1 and 3 shown, a limit flange 311 having an arc-shaped structure is longitudinally attached to the bottom of the inner side surface of the support plate 31, and the limit flange 311 is circumferentially and slidably attached to the inner side surface of the corresponding guiding support plate 21.

[0035] By adopting the above technical solution, the provided limit flange 311 can prevent the support plate 31 from radially extruding the limit screw 41, and can effectively improve the service life of the limit screw 41.

[0036] As Figure 4 shown, a pointer 214 is longitudinally attached to the middle of the outer side surface of the support plate 31, and the pointer 214 is circumferentially and slidably attached to the angle line 213 engraved on the outer edge of the corresponding guiding support plate 21.

[0037] By adopting the above technical solution, the pointer 214 and the angle line 213 are used in cooperation, and the specific tilting angle can be displayed, which is convenient for the observer to make test records and summarize experience.

[0038] As Figure 1 and 3 shown, longitudinal slots 33 with an inverted T-shaped cross-section are horizontally and oppositely formed on the top surface of the mounting plate 3, and one end of each slot 33 penetrates through the corresponding end face of the mounting plate 3; insertion rods 511 are horizontally and oppositely and vertically connected to the bottom surface of the lamp inspection box 5, and the insertion rods 511 are horizontally inserted and matched with the corresponding slots 33.

[0039] By adopting the above technical solution, the cooperation of the slots 33 and the insertion rods 511 can facilitate the disassembly and fixing of the lamp inspection box 5 as needed.

[0040] As Figure 1 and 3 shown, a retaining strip 6 is attached to the outer end face of the insertion rod 511, and the ends of the retaining strip 6 are respectively screwed and fixed to the screw holes 34 formed in the end face of the mounting plate 3 through fastening bolts 61.

[0041] By adopting the above technical solution, the cooperation of the retaining strip 6 and the fastening bolts 61 can prevent the insertion rod 511 from sliding out of the slot 33.

[0042] As Figures 5 to 7 shown, the lamp inspection box 5 includes an outer frame 51, a light-transmitting plate 52 is sealed to the top surface of the outer frame 51, and the surface of the light-transmitting plate 52 is flush with the edge of the outer frame 51; the clamping mechanism 7 includes a fixed clamping rod 71 with a U-shaped right-angle structure, the fixed clamping rod 71 is fixedly arranged on the top surface of the outer frame 51, and the inner side of the fixed clamping rod 71 is flush with the corresponding edge of the light-transmitting plate 52; a movable clamping rod 72 is horizontally spanned between the vertical parts of the fixed clamping rod 71, and the end face of the movable clamping rod 72 is slidably attached to the inner side surface of the corresponding vertical part of the fixed clamping rod 71; a guide groove 711 is longitudinally formed through the side surface of the vertical part of the fixed clamping rod 71 along its long side direction; convex rods 721 are integrally and horizontally and vertically connected to the middle of the end face of the movable clamping rod 72, the convex rods 721 are slidably inserted and matched with the corresponding guide grooves 711, and the end face of the convex rod 721 is connected to a pressing assembly 73 longitudinally arranged on the outer side of the corresponding vertical part of the fixed clamping rod 71, and the pressing assembly 73 is used to drive the movable clamping rod 72 to move and be positioned along the guide groove 711.

[0043] By adopting the above technical solution, during use, the extracted TFT-LCD glass substrate can be placed against the surface of the light-transmitting plate 52, and then the moving clamping rod 72 is driven by the pressing assembly 73 to cooperate with the fixed clamping rod 71 to clamp and fix the TFT-LCD glass substrate; in this way, TFT-LCD glass substrates of various sizes can be adapted to prevent them from falling off the lamp inspection box 5 during the tilting process.

[0044] As Figure 5 shown, the pressing assembly 73 includes a stop block 731, the stop block 731 is vertically connected to the end face corresponding to the convex rod 721, a positioning screw rod 733 is longitudinally and movably arranged in the stop block 731, the bottom end of the positioning screw rod 733 is vertically and fixedly connected to a mounting block 732 arranged at the bottom of the fixed clamping rod 71, a spring 734 is axially sleeved on the positioning screw rod 733, and the bottom end of the spring 734 is connected to the mounting block 732, and its top end is connected to the stop block 731; a positioning nut 735 is screwed on the upper part of the positioning screw rod 733, and the positioning nut 735 is located above the corresponding stop block 731.

[0045] By adopting the above technical solution, manually rotating and moving the positioning nut 735 longitudinally can drive the moving clamping rod 72 to displace along the positioning screw rod 733, and the arranged spring 734 can play a buffering effect to prevent the moving clamping rod 72 from damaging the edge of the TFT-LCD glass substrate during the clamping process.

[0046] When the present invention is implemented, first, the extracted TFT-LCD glass substrate is fixedly placed on the light-transmitting plate 52 of the lamp inspection box 5 through the clamping mechanism 7, and then, during the observation process, an operator rotates the handle 2231 to drive the rotating rod 223 to rotate around the bearing seat 221, and the rotating rod 223 synchronously drives the spiral rack 222 to travel along the arc-shaped tooth track 224, thereby driving the mounting plate 3 to tilt and displace along the guiding support plate 21. At the same time, by tightening the locking nut 43, the cushion block 42 is made to closely adhere to the inner top surface of the stroke groove 211, so as to achieve the purpose of fixing the tilting angle and facilitating manual observation.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
