Referring to fig. 1, a silicon rod 100 is generally of a rectangular parallelepiped block-shaped structure. During the fabrication of the solar cell, the silicon rod 100 needs to be transported to a corresponding dicing station.

When the existing transport trolley is used for transporting the silicon rod 100, the silicon rod 100 is easy to displace in the transportation process, and the silicon rod 100 is easy to damage.

Therefore, the present application further improves the transportation apparatus, so that the transportation quality problem of the silicon rod 100 can be improved to some extent. In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The present application provides a transportation device 1. Referring to fig. 2, the transport device 1 includes an transfer shelf 10 and an AGV carriage 20, and the transfer shelf 10 is disposed on the AGV carriage 20.

With the AGV trolley 20, the silicon rods 100 placed in the turnaround shelves 10 on the AGV trolley 20 can be transported to a desired position.

With continued reference to FIG. 2, the epicyclic shelf 10 includes a cargo box 11 and a push-clip mechanism 12.

Referring to fig. 3, the container 11 has a plurality of placement areas spaced apart along the first direction D1 therein, each for independently placing the silicon rods 100. Opposite ends of the cargo box 11 at each placement area are provided with a first stop 111 and a second stop 112, respectively.

Referring to fig. 4, the push-clamping mechanism 12 includes a chassis 121 and a plurality of push members 122 protruding from the chassis 121 and disposed at intervals along a first direction D1, wherein the chassis 121 is movably disposed between the first blocking members 111 and the second blocking members 112 of the plurality of placement areas, so that one side of the silicon rod 100 of each placement area abuts against one push member 122, and the other side abuts against the first blocking member 111 and the second blocking member 112 of the placement area.

The transport device 1 provided by the examples of the present application is described in further detail below with reference to the accompanying drawings.

The epicyclic shelf 10 is used to carry silicon rods 100 and is connected to an AGV trolley. To facilitate carrying the silicon rods 100, the epicyclic shelf 10 comprises a cargo box 11.

Wherein a plurality of placement areas are provided inside the cargo box 11 to place a plurality of silicon rods 100. In order to facilitate the placement of the silicon rods 100 in each placement area in a one-to-one correspondence, first and second stops 111 and 112 are provided at opposite ends of the cargo box 11 at each placement area, respectively. Each placement area may be spaced apart using a first stop 111 and a second stop 112.

Illustratively, as shown in FIG. 3, three placement areas are provided within the cargo box 11.

The cargo box 11 is illustratively formed of a floor, and four side panels interconnected about the edges of the floor. The bottom plate is used for carrying the silicon rods 100, and the four side plates are used for protecting the silicon rods 100, so that the probability that gas components outside the container 11 collide with the silicon rods 100 in the container 11 is reduced.

The present application is not limited to the specific form of the first and second stops 111, 112, and in one possible embodiment, please continue to refer to fig. 3, in which the first and second stops 111, 112 are both plate-shaped. Further, the first stop 111 has a first panel 1111 adjacent to the placement area and the second stop 112 has a second panel 1121 adjacent to the placement area, the first panel 1111 and the second panel 1121 being coplanar and perpendicular to the floor of the cargo box 11.

The plate-shaped first blocking piece 111 and the plate-shaped second blocking piece 112 are coplanar near the plate surface of the placement area and are perpendicular to the bottom plate of the container 11, so that when the silicon rod 100 placed in the placement area abuts against the first blocking piece 111 and the second blocking piece 112, the abutting area of one side of the silicon rod 100 is larger, and the abutting force is more uniform.

It is noted that the plate-like first and second stoppers 111 and 112 are coplanar near the plate surface of the placement area, meaning that both plate surfaces can simultaneously contact the side surfaces of the silicon rod 100. Both panels are perpendicular to the floor of the cargo box 11: since the silicon rod 100 is generally rectangular in shape, when the bottom surface of the silicon rod 100 is placed on the floor of the cargo box 11, the side surface of the silicon rod 100 perpendicular to the floor is parallel to the plate surfaces of the two stoppers. Coplanar and perpendicular refer to what can be achieved industrially, with angles similar to zero degrees and 90 degrees, respectively, but are not limited to standard zero degrees and 90 degrees.

Further, flexible first protection pads 115 may be disposed at the first board 1111 and the second board 1121, so as to reduce the probability of damage of the silicon rod 100 during the hard contact process when the silicon rod abuts against the first board 1111 and the second board 1121. The material of the first protection pad 115 may be silica gel.

Further, with continued reference to fig. 3, the opposite ends of the cargo box 11 at each receiving area are also provided with a third stop 113 and a fourth stop 114, respectively. The third stopper 113 is opposite to the first stopper 111, and the fourth stopper 114 is opposite to the second stopper 112. The first stopper 111, the second stopper 112, the third stopper 113 and the fourth stopper 114 together form a placement area.

Further, with continued reference to fig. 3, the first and second stoppers 111 and 112 are spaced apart along the second direction D2, and the third and fourth stoppers 113 and 114 are spaced apart along the second direction D2.

Further, in one possible embodiment, an opening 116 may be provided in the bottom of the cargo box 11. Illustratively, the first and second baffles 111, 112 are spaced from one another by an opening 116, while the third and fourth baffles 113, 114 are spaced from one another by an opening 116.

The pushing and clamping mechanism 12 is used for pushing the silicon rod 100 placed in the corresponding placement area through the pushing piece 122, so that the silicon rod 100 is clamped between the pushing piece 122 and the first blocking piece 111 and the second blocking piece 112, and the probability of sliding of the silicon rod 100 in the container 11 is reduced.

With continued reference to fig. 4, the plurality of pushing members 122 are disposed on the chassis 121 at intervals along the first direction D1 and protrude from the chassis 121. The bottom frame 121 is movably disposed between the first stoppers 111 and the second stoppers 112 of the plurality of placement areas, so that one side of the silicon rod 100 of each placement area abuts against one of the pushing members 122, and the other side abuts against the first stoppers 111 and the second stoppers 112 of the placement area by the pushing members 122.

In one possible embodiment, the chassis 121 is disposed below the cargo box 11 and a plurality of pushers 122 attached to the chassis 121 extend from the opening 116 into the interior of the cargo box 11 in a one-to-one correspondence with the first and second stops 111, 112 at the placement area.

Further, in order to facilitate pushing the plurality of pushing members 122 simultaneously by the chassis 121 in a direction approaching the first stopper 111 and the second stopper 112 to clamp the silicon rod 100, in one possible embodiment, the distance between two adjacent pushing members 122 is equal to the distance between two adjacent placement areas.

It should be noted that, when the distances between two adjacent pushing members 122 are equal to the distances between two adjacent placement areas, the distances between the two pushing members are not absolutely equal, and the actual distances between the two pushing members can be adjusted correspondingly within a reasonable error range or tolerance range in industrial manufacturing.

Since the plurality of silicon rods 100 are generally the same in size, the distance between two adjacent pushing members 122 is equal to the distance between two adjacent placement areas, when the silicon rods 100 at the plurality of placement areas need to be clamped, after the plurality of pushing members 122 are simultaneously moved a certain distance along the first direction D1, each pushing member 122 can abut against one side of the silicon rod 100 in the corresponding placement area, and simultaneously the plurality of silicon rods 100 are clamped in the corresponding placement area.

Alternatively, in one possible embodiment, the distance between two adjacent pushers 122 is not equal to the distance between two adjacent placement areas. The silicon rods 100 of the respective placement zones may be selectively clamped or relaxed by individually adjusting the movement of the push member 122 of each placement zone.

Further, in order to reduce the probability of the pushing member 122 damaging the silicon rod 100 during pushing of the silicon rod 100, in one possible embodiment, the pushing member 122 includes a first pushing plate 1221 and a second pushing plate 1222 spaced apart along the second direction D2. Further, the first and second push plates 1221, 1222 are each perpendicular to the floor of the cargo box 11.

The first push plate 1221 and the second push plate 1222 are utilized to push the silicon rod 100 at the same time, so that the stress area on one side of the silicon rod 100 is larger, the stress is more uniform, and the pushing process is more stable.

Further, in one possible embodiment, a flexible second guard pad 123 may be provided on the first push plate 1221 proximate to the third plate 12211 of the placement area, and a flexible second guard pad 123 may be provided on the second push plate 1222 proximate to the fourth plate 12221 of the placement area. The second protection pad 123 may be a silicone pad, for example.

The flexible protection pad is arranged at the position of the plate surface which is used for abutting against the silicon rod 100, so that the probability of damage of the silicon rod 100 during clamping can be reduced.

The present application does not limit how the chassis 121 may be movably disposed in each placement area, and in one possible embodiment, the push-grip mechanism 12 further includes a transmission member 124, where the transmission member 124 includes a lead screw 1241, a guide rod 1242, and a slider 1243. The screw 1241 is used for connecting with the driver 125; the slider 1243 is screwed with the screw 1241 and is simultaneously slidingly connected with the guide rod 1242. The chassis 121 is fixedly connected to the slider 1243, so as to drive the chassis 121 to move along the first direction D1, so that the pushing member 122 approaches or separates from the corresponding first blocking member 111 and the second blocking member 112.

Further, to facilitate the securement of the drive member 124, in one possible embodiment, a bracket 126 is provided at the bottom of the cargo box 11. The bracket 126 is secured to the bottom of the cargo box and the actuator 125 and guide rods 1242 are secured to the bracket 126 so that the undercarriage 121 may be supported below the cargo box 11 by the slide 1243.

Illustratively, the bracket 126 includes a "n" shaped drive mount, and a guide bar support pad.

Further, a lead screw support pad may be disposed at an end of the lead screw 1241 remote from the driver 125. The screw 1241 is rotatably connected with the screw support cushion block through a bearing.

Further, the bracket 126 may further include four legs, each of which has a roller disposed under it.

The present application is not limited to the type of AGV cart 20 and the relevant personnel may make corresponding selections as needed in the existing AGV cart.

Further, an aviation plug may be disposed at the container 11, and the aviation plug may be electrically connected to the driver 125 in a conductive communication manner, so as to facilitate the transportation of the silicon rod 100 by using the transportation device 1 in cooperation with the silicon rod scheduling system.

When a certain silicon rod 100 is required, a rod-requiring instruction is issued to a workshop solidification warehouse, the solidification warehouse system automatically matches silicon rods meeting the process conditions and feeds back the quantity of the silicon rods which can be discharged by a silicon rod scheduling system, feedback of the solidification warehouse system is obtained, a calling request is issued to a control system of an AGV trolley 20, and the control system commands the AGV trolley 20 to transport a turnover shelf 10 to a solidification blanking port for receiving. After the AGV trolley 20 transports the turnover goods shelf 10 to the coordinates of the discharging opening of the curing warehouse, after the docking mechanism of the curing warehouse detects the turnover goods shelf 10, the aviation plug in the turnover goods shelf 10 is electrified with the socket above the docking mechanism, and the curing warehouse system transmits a signal to the driver 125 and controls the motor to drive the underframe 121 to move so as to clamp the silicon rod 100 according to the size type of the silicon rod 100 and the matching corresponding frequency.

The working principle of the transporting device 1 provided in the embodiment of the present application is as follows:

the silicon rods 100 are placed in corresponding placement areas in the container 11 in a one-to-one correspondence manner, then the underframe 121 in the pushing and clamping mechanism 12 is utilized to drive the pushing piece 122 arranged on the underframe 121 to move along the first direction D1, so that one side of the silicon rod 100 is abutted against the pushing piece 122, the other side of the silicon rod 100 is abutted against the first blocking piece 111 and the second blocking piece 112, the silicon rod 100 is clamped, and further the movement of the silicon rod 100 in each placement area is limited. The silicon rod 100 placed in the container 11 on the AGV car is then transported to a desired position using the AGV car.
