DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In the description of the embodiments of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "inner", "outer", "upper", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is customarily placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0022] As shown in the front view of the material component Figure 4a and the top view of the material component Figure 4b As shown, this embodiment is used for conveying the tray 41. At least two parallel bosses 42 for supporting the tray 41 are formed on the bottom surface of the tray 41, and the length direction of the boss 42 is perpendicular to the length direction of the tray 41.

[0023] Specifically, in this embodiment, the photovoltaic modules 43 are stacked on the tray 41, and the tray 41 is stably conveyed by carrying and stabilizing the tray 41 to stably convey the photovoltaic modules 43. In this embodiment, three bosses 42 are formed on the bottom surface of the tray 41, and there are gaps on the sides of the bosses 42 for placing the forklift forks, so that the forklift forks extend into the gaps between the bosses 42 to lift the tray 41.

[0024] As Figure 1 shown, this embodiment includes: a first conveyor 1 for conveying the tray 41, and the conveying direction of the first conveyor 1 is perpendicular to the length direction of the boss 42; a second conveyor 3 with its feeding end connected to the discharging end of the first conveyor 1, and the conveying direction of the second conveyor 3 is perpendicular to the conveying direction of the first conveyor 1. At least two channels 34 are formed at the feeding end of the second conveyor 3. The channels 34 can always keep the bosses 42 passing through themselves in contact with the conveying surface of the second conveyor 3, and the channels 34 can limit the bosses 42 that cannot pass through themselves from contacting the conveying surface of the second conveyor 3.

[0025] Specifically, the first conveyor 1 conveys the tray 41 towards the feeding end of the second conveyor 3, where the boss 42 is in contact with the conveying surface of the first conveyor 1. The length directions of the three bosses 42 are all perpendicular to the conveying direction of the first conveyor 1, so that when the first conveyor 1 conveys the boss 42, its length direction is always parallel to the conveying direction of the second conveyor 3. As a result, when the three bosses 42 move to the feeding end of the second conveyor 3, they can pass through the channels 34 along the length direction and then be in contact with the conveying surface of the second conveyor 3, realizing that the second conveyor 3 conveys the tray 41 to the next process along the length direction of the three bosses 42.

[0026] Among them, the second conveyor 3 includes a second cavity 33 which cannot carry the tray 41. If the boss 42 gradually enters the second cavity 33 during the conveying process of the second conveyor 3, the center of gravity of the material assembly 4 will gradually move towards the second cavity 33, thereby causing the tray 41 to tip over.

[0027] Secondly, the feeding end of the second conveyor 3 forms a blocking surface for blocking the boss 42 from entering its conveying surface. The blocking surface forms a channel 34 corresponding to the area of the conveying surface of the second conveyor 3 that can carry the tray 41, so that the second conveyor 3 can carry and convey the boss 42 passing through the channel 34. Furthermore, the second conveyor 3 can stably convey the tray 41, avoiding the tray 41 tipping over due to moving towards the second cavity 33 and causing the photovoltaic module 43 to fall. Specifically, when the boss 42 moves towards the feeding end of the second conveyor 3, the projection of the end face of the boss 42 along the conveying direction of the second conveyor 3 cannot completely pass through the channel 34, and the boss 42 cannot pass through the channel 34 and enter the second conveyor 3, so it always stays on the first conveyor 1 and triggers an alarm to remind the operator to adjust the position of the tray 41; when the boss 42 moves towards the feeding end of the second conveyor 3, the projection of the end face of the boss 42 along the conveying direction of the second conveyor 3 completely passes through the channel 34, and the end face of the boss 42 enters the channel 34. The first conveyor 1 continuously conveys the boss 42 towards the second conveyor belt 32, so that the boss 42 gradually passes through the channel 34 and contacts the second conveyor belt 32. If there is an angular deviation between the length direction of the boss 42 and the length direction of the second conveyor belt 32, the channel 34 can continuously correct the length direction of the boss 42 during the continuous movement of the boss 42 to make it coincide with the length direction of the second conveyor belt 32, so that the second conveyor belt 32 can carry the boss 42 passing through the channel 34 and stably convey the boss 42.

[0028] Furthermore, the second conveyor 3 includes: at least two second conveyor belts 32 for carrying and conveying the boss 42, the conveying direction of the second conveyor belt 32 is the same as the length direction of the boss 42, and each second conveyor belt 32 can carry at most one boss 42; and a limit baffle 35 provided at the feeding end of the second conveyor belt 32, the distance between the end face of the limit baffle 35 and the opposite face of the boss 42 is less than the width of a single boss 42, and the distance between the end face of the limit baffle 35 and the opposite face of the boss 42 is not less than zero.

[0029] Specifically, in this embodiment, three second conveyor belts 32 are arranged in parallel along the conveying direction of the second conveyor 3, and the second cavity 33 exists in the gap between the adjacent second conveyor belts 32. The second conveyor belts 32 correspond to the bosses 42 respectively, so that the second conveyor belt 32 can stably carry and convey the bosses 42. Secondly, the larger surface of the limit baffle 35 is the limit surface for limiting the movement of the boss 42. It is fixedly connected to the feeding end of the second conveyor 3 by bolts to prevent the boss 42 from entering the second cavity 33. In the process of the boss 42 passing through the channel 34, the minimum distance between the right end face of the boss 42 and the end face of the limit baffle 35 is less than the width of a single boss 42, so that when the boss 42 moves toward the second conveyor belt 32, its bottom surface will not be separated from the second conveyor belt 32, and the second conveyor belt 32 can always provide support for the boss 42, thereby stably conveying the boss 42; when The minimum distance between the right end face of the boss 42 and the end face of the limit baffle 35 is greater than the width of a single boss 42. The boss 42 moves toward the second conveyor belt 32, and there is an angle deviation between the boss 42 and the conveying direction of the second conveyor belt 32. The channel 34 cannot correct the length direction of the boss 42 to a suitable angle, so that the boss 42 will continue to move toward the second cavity 33, causing the center of gravity of the material assembly 4 to gradually deviate from the second conveyor belt 32 and move toward the second cavity 33 until the center of gravity falls in the second cavity 33, causing the tray 41 to overturn, the photovoltaic assembly 43 to fall, and a production accident to occur. Secondly, the distance between the side of the limit baffle 35 and the side of the boss 42 cannot be less than zero, and can be equal to zero or greater than zero.

[0030] Combination Figure 2 As shown, the second conveyor 3 further includes a straightening baffle 36 whose larger surface coincides with the end surface of the limiting baffle 35 , and the larger surface of the straightening baffle 36 and the top surface of the second conveyor belt 32 form a channel 34 .

[0031] Specifically, both end surfaces of the limit baffle 35 are fixedly connected to the straightening baffle 36, and the opposite surface of the straightening baffle 36 and the second conveyor belt 32 is a larger surface, so that the channel 34 applies pressure to the side of the boss 42 through the larger surface of the straightening baffle 36, thereby continuously correcting the angle between the length direction of the boss 42 and the conveying direction of the second conveyor belt 32, and then the channel 34 carries and conveys the boss 42 through the top surface of the second conveyor belt 32. Among them, when the larger surface of the straightening baffle 36 faces the larger surface of the straightening baffle 36, the channel 34 is formed of two side surfaces of the larger surface of the straightening baffle 36, and the top surface of the second conveyor belt 32 constitutes its bottom surface, thereby being able to correct the length direction of the boss 42 so that it can always be carried by it when moving toward the second conveyor belt 32.

[0032] Furthermore, the first conveyor 1 includes: a first mounting bracket 11, in the middle area of which a first cavity 13 is formed; and at least two first conveyor belts 12 disposed on the top surface of the first mounting bracket 11, the conveying direction of the first conveyor belt 12 being the length direction of the first mounting bracket 11, and the area between the first conveyor belts 12 arranged in parallel along the length direction being the first cavity 13.

[0033] Specifically, the first mounting bracket 11 is a frame composed of channel aluminum, and its top end is provided with two first conveyor belts 12 arranged in parallel along the conveying direction. The first cavity 13 is located within the gap between the first conveyor belts 12, enabling the first conveyor belts 12 to carry and convey the bottom surface of the tray 41 and transport it to the feeding end of the second conveyor belt 32. During this process, the middle area of the tray 41 is always in contact with the first cavity 13, allowing the components placed in the first cavity 13 to exert a force on the bottom surface of the tray 41 without affecting the conveyance of the first conveyor belts 12.

[0034] Secondly, the length direction of the boss 42 is perpendicular to the conveying direction of the first conveyor belt 12. The first conveyor belts 12 respectively carry both ends of the boss 42, such that even if there is an angular deviation between the length direction of the boss 42 and the conveying direction of the first conveyor belt 12, the first conveyor belts 12 may still continue to carry the boss 42 and thus stably transport it to the feeding end of the second conveyor belt 32.

[0035] As Figure 3 shown, this embodiment further includes a lifting transfer machine 2 disposed in the first cavity 13. The lifting transfer machine includes: a lift 21, the top surface of which can move in the vertical direction; and a conveying member 22 disposed on the top surface of the lift 21, the conveying direction of the conveying member 22 being perpendicular to the conveying direction of the first conveyor belt 12, and the conveying surface of the conveying member 22 being at the same height as the conveying surface of the second conveyor 3. The conveying member 22 can push the boss 42 towards the channel 34.

[0036] Specifically, the lifting and transferring machine can adjust the position of the projection of the conveying member 22 along the conveying direction relative to the channel 34 by adjusting the position of the second conveyor 3 . Secondly, the lift 21 can drive the conveying surface of the conveying member 22 up and down through a vertically placed cylinder or screw drive, so that there is no height difference between the conveying surface of the second conveyor belt 32 and its conveying surface, thereby reducing the obstruction encountered by the boss 42 during the movement toward the channel 34, so that only the limit baffle 35 can limit the movement of the boss 42 along the length direction; secondly, when the conveying member 22 pushes the boss 42 through the channel 34 to move toward the second conveyor belt 32, the length direction of the boss 42 does not shift relative to the conveying direction of the conveying member 22, so that when the first conveyor 1, the lifting and transferring machine 2 and the second conveyor 3 are placed, by adjusting the conveying direction of the conveying member 22 to be parallel to the conveying direction of the second conveyor belt 32, and the projection of the conveying member 22 along the conveying direction can cover the channel 34, the limit baffle 35 can block the boss 42 or the channel 34 can correct the angle of the length direction of the boss 42 relative to the conveying direction of the second conveyor belt 32, so that the second conveyor belt 32 can stably convey the boss 42 to the next process.

[0037] Furthermore, the number of the conveying members 22 is the same as the number of the bosses 42 , the conveying surface of a single conveying member 22 carries and conveys a single boss 42 , and a single channel 34 extends along the conveying direction of the second conveyor 3 and intersects with a single conveying member 22 .

[0038] Specifically, the lifting and transferring machine 2 includes three conveying members 22, which are composed of rollers, so that a single conveying member 22 can convey a single boss 42, thereby making the movement of the three bosses 42 independent. When the conveying member 22 pushes the boss 42 close to the channel 34:

[0039] There is an angle deviation between the length direction of the boss 42 and the conveying direction of the second conveyor belt 32, but the right end face of the boss 42 can pass through the channel 34, and the three conveying members 22 adjust their respective conveying speeds and continue to push the boss 42 to move toward the second conveyor belt 32, so that the length direction of the boss 42 can rotate under the limit of the straightening baffle 36 and the push of the conveying member 22, so that its bottom surface can always be in contact with the second conveyor belt 32 and be conveyed by it;

[0040] There is an angular deviation between the length direction of the boss 42 and the conveying direction of the second conveyor belt 32. The right end face of the boss 42 closest to the channel 34 cannot pass through the channel 34. The three conveying members 22 adjust their respective conveying speeds and continue to push the boss 42 so that its length direction gradually coincides with the conveying direction of the second conveyor belt 32, and an alarm is issued to notify the operator to adjust the position of the boss 42 so that it can pass through the channel 34.

[0041] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
