[0043] like Figures 3 to 5 As shown, the transparent bearing assembly includes a mounting seat 4 and a transparent member 5, the mounting seat 4 is connected to the frame 1, the mounting seat 4 is provided with a mounting groove 40 extending along the second direction, and the mounting groove 40 extends along the third direction, and the transparent member 5 is arranged in the mounting groove 40.

Among them, the first direction, the second direction and the third direction are not parallel to each other and are not collinear.

[0044] Preferably, the second direction is a vertical direction, the first direction and the third direction are horizontal directions, and the first direction, the second direction and the third direction are perpendicular to each other. More specifically, in this embodiment, the first direction is the length direction of the frame 1, that is, the conveying direction of the material; the second direction is the height direction of the frame 1, that is, the vertical direction, and the third direction is the width direction of the frame 1.

[0045] In this embodiment, the outer dimensions of the transparent member 5 are matched with the dimensions of the mounting groove 40, and the transparent member 5 can be directly placed into the mounting groove 40, which has the advantages of simple structure and convenient installation. In other embodiments, the transparent member 5 can be fixed in other detachable ways in this embodiment, and even the transparent member 5 and the mounting seat 4 can be bonded by an adhesive layer, and the adhesive layer can be destroyed when replacing.

[0046] As an example, the transparent member 5 is plate-shaped and extends along the third direction. More specifically, the transparent member 5 is a glass plate. A highly transparent glass plate can be used.

[0047] As an example, the upper surface of the mounting seat 4 is flush with the upper surface of the first conveying assembly 2, the upper surface of the first conveying assembly 2 and the upper surface of the second conveying assembly 3 are coplanar, and the thickness of the transparent member 5 is less than or equal to the depth of the first mounting groove 491.

Of course, the upper surface of the transparent member 5 is lower than the upper surface of the mounting seat 4, which can also facilitate the camera assembly 6 to shoot the material above the transparent member 5.

[0048] like Figures 3 to 5 As shown, as an example, the mounting seat 4 includes a first mounting seat 41 and a second mounting seat 42 spaced apart along a first direction, the mounting groove 40 includes a first groove 43 arranged on the first mounting seat 41 and a second groove 44 arranged on the second mounting seat 42, the first groove 43 and the second groove 44 both extend along a third direction, and the transparent member 5 is arranged in the first groove 43 and the second groove 44.

[0049] Specifically, the first mounting seat 41 has a first plane 431 and a first side surface 432 which are perpendicular to each other, the second groove 44 has a second plane 441 and a second side surface 442 which are perpendicular to each other, the first side surface 432 and the second side surface 442 are arranged opposite to each other, and the first plane 431 and the second plane 441 are located on the same horizontal plane. The opposite two sides of the transparent member 5 are located between the first side surface 432 and the second side surface 442, and the opposite two ends of the bottom surface of the transparent member 5 are overlapped on the first plane 431 and the second plane 441 respectively.

[0050] As an example, the first mounting seat 41 is arranged close to the first conveying component 2, and the second mounting seat 42 is arranged close to the second conveying component 3. A guide slope 48 is arranged at one end of the first mounting seat 41 close to the first conveying component 2, and the guide slope 48 gradually tilts upward along the conveying direction of the first conveying component 2 until it is flush with the upper surface of the first conveying component 2, and the angle between the guide slope 48 and the top surface of the first mounting seat 41 is 15°~30°. Preferably, the angle between the guide slope 48 and the top surface of the first mounting seat 41 can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29° or 30°. Refer to Figure 3 and Figure 4 As an example, the transparent member 5 is a rectangular plate. The upper surface of the first mounting seat 41 is provided with a first avoidance hole 493 and a second avoidance hole 494, both of which extend along the second direction, the first avoidance hole 493 has a first opening, and the first avoidance hole 493 is connected to the first groove 43 through the first opening, the second avoidance hole 494 has a second opening, and the second avoidance hole 494 is connected to the first groove 43 through the second opening, the first avoidance hole 493 and the second avoidance hole 494 are provided at both ends of the first groove 43 along the third direction, one of the corners of the transparent member 5 built in the first groove 43 is placed in the first opening, and the other corner of the transparent member 5 built in the first groove 43 is placed in the second opening.

[0051] A third avoidance hole 495 and a fourth avoidance hole 496 are provided on the upper surface of the second mounting seat 42. The third avoidance hole 495 and the fourth avoidance hole 496 both extend along the second direction. The third avoidance hole 495 has a third opening. The third avoidance hole 495 is connected to the second groove 44 through the third opening. The fourth avoidance hole 496 has a fourth opening. The fourth avoidance hole 496 is connected to the second groove 44 through the fourth opening. The third avoidance hole 495 and the fourth avoidance hole 496 are provided at both ends of the second groove 44 along the third direction. One of the corners of the transparent part 5 built into the second groove 44 is placed in the third opening, and the other corner of the transparent part 5 built into the second groove 44 is placed in the fourth opening.

[0052] In actual production, it is difficult and costly to chamfer glass. However, when the unchamfered glass is installed in the mounting groove 40, the four corners of the glass are likely to collide with the side wall of the mounting groove 40, resulting in edge collapse and cracking. Therefore, the four corners of the mounting groove 40 are enlarged by the first avoidance hole 493, the second avoidance hole 494, the third avoidance hole 495 and the fourth avoidance hole 496, leaving redundant space for placing the glass, thereby reducing the collision between the corners of the glass and the mounting groove 40, thereby protecting the transparent member 5 made of glass.

[0053] As an example, a first mounting hole 497 and a second mounting hole 498 are provided on the top surface of the first mounting seat 41, and the first mounting hole 497 and the second mounting hole 498 both extend along the second direction, and the first mounting hole 497 and the second mounting hole 498 are both used to mount the first mounting seat 41 on the frame 1. A third mounting hole 499 and a fourth mounting hole 500 are provided on the top surface of the second mounting seat 42, and the third mounting hole 499 and the fourth mounting hole 500 both extend along the second direction, and the third mounting hole 499 and the fourth mounting hole 500 are both used to mount the second mounting seat 42 on the frame 1.

[0054] In this embodiment, the first mounting hole 497, the second mounting hole 498, the third mounting hole 499 and the fourth mounting hole 500 are all threaded holes, and the first mounting seat 41 and the second mounting seat 42 are fixed to the frame body 1 by passing bolts through the frame body 1 and screwing into the threaded holes. In other embodiments, the first mounting hole 497, the second mounting hole 498, the third mounting hole 499 and the fourth mounting hole 500 may be through holes, and the first mounting seat 41 and the second mounting seat 42 are respectively mounted on the frame body 1 by passing each bayonet through the frame body 1 and snapping into the first mounting hole 497, the second mounting hole 498, the third mounting hole 499 and the fourth mounting hole 500.

[0055] Reference Figure 6 In one embodiment, the cross section of the mounting seat 4 gradually decreases from the top surface to the bottom surface thereof, the orthographic projection of the end of the mounting seat 4 close to the first direction on the upper surface of the mounting seat 4 coincides with the orthographic projection of the end of the first conveying component 2 close to the mounting seat 4 on the upper surface of the mounting seat 4, and the orthographic projection of the end of the mounting seat 4 close to the second conveying component 3 on the upper surface of the mounting seat 4 coincides with the orthographic projection of the end of the second conveying component 3 close to the mounting seat 4 on the upper surface of the mounting seat 4. Through the above arrangement, the interval between the two sides of the mounting seat 4 along the first direction and the first conveying component 2 and the second conveying component 3 can be reduced, so that the material can be smoothly conveyed from the first conveying component 2 to the second conveying component 3.

[0056] Reference Figure 5 As an example, the first mounting seat 41 has a first sub-side surface 411 and a second sub-side surface 412, and opposite sides of the first sub-side surface 411 are respectively connected to the guiding inclined surface 48 and the second sub-side surface 412, and the first sub-side surface 411 and the second sub-side surface 412 are both arranged on a side of the first mounting seat 41 close to the first conveying component 2, and the first sub-side surface 411 and the second sub-side surface 412 are both arranged facing the first conveying component 2, and the second sub-side surface 412 is located at the top of the first sub-side surface 411, and the angle between the first sub-side surface 411 and the second sub-side surface 412 is 120°-150°;

The first sub-side surface 411 and the second sub-side surface 412 allow the facing surfaces of the first mounting seat 41 and the first conveying component 2 to be as close as possible, and reduce the gap between the upper surface of the first conveying component 2 and the upper surface of the first mounting seat 41. When the material is conveyed to the vicinity of the gap between the upper surface of the first conveying component 2 and the upper surface of the first mounting seat 41, it can smoothly move from the upper surface of the first conveying component 2 to the upper surface of the first mounting seat 41. Similarly, the third sub-side surface 421 and the fourth sub-side surface 422 are used to reduce the gap between the second conveying component 3 and the second mounting seat 42, and will not be described in detail.

The mounting seat 4 can be a separate integral component, or it can be the mounting seat 4 which is divided into the first mounting seat 41 and the second mounting seat 42 in the previous embodiment.
