[0002] With the rapid development of the photovoltaic industry, the storage of photovoltaic modules has also undergone significant changes. The storage method of enterprises has gradually changed from manual handling and stacking to automated storage systems. Its main structure includes shelf systems and automated storage and retrieval systems. The shelf systems include multi-layer shelves with standard spacing and standard-sized pallets for carrying photovoltaic modules. The automated storage and retrieval systems include stackers for storing and retrieving goods, shuttle vehicles for horizontal movement, and conveyors for transporting goods in and out of the warehouse.

[0003] Among them, the conveyor transports the photovoltaic components placed on the pallet to the interior of the warehouse. Secondly, in order to achieve greater space utilization of the shelf, the photovoltaic components will be processed by stacking together, specifically, multiple pallets carrying photovoltaic components are stacked up in the height direction. The existing stacking device uses a chain machine to drive the fork to move up and down and then drive the pallet to move up and down. However, when the inventor of this application implemented the existing stacking device to stack multiple layers of pallets, he found that: the fork carrying the pallet will be flexibly deformed by the gravity of the pallet and the photovoltaic components during the rising process. Secondly, the chain machine only applies a pulling force to one end of the fork to drive the photovoltaic components to rise. The end of the fork away from the pulling force point will be slightly lower than the other end, causing the top surface of the fork to be not a horizontal plane, and then causing the rising pallet to deviate in the horizontal direction, and then the photovoltaic components after the support cannot be aligned, which may cause the photovoltaic components after the support to be unable to be placed in the storage position of the stereoscopic warehouse, and may also cause the center of gravity of the upper photovoltaic components to be unstable and fall.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figure 1 As shown, the embodiment of the utility model performs pallet processing on the material assembly 3, and the material assembly 3 includes a photovoltaic assembly 31 and a pallet 32 ​​that carries the photovoltaic assembly 31.

[0023] Specifically, the pallet 32 ​​in the photovoltaic warehousing field includes a mother pallet 32 ​​and a child pallet 32, wherein the child pallet 32 ​​is placed on the mother pallet 32 ​​according to the placement rules to form an overall material component 3 to ensure its uniform size, and then it is placed in a standard size storage location of the stereoscopic warehouse for storage to improve the volume utilization rate of the stereoscopic warehouse.

[0024] Combination Figure 2 As shown, this embodiment includes: a supporting component 1, which includes a mobile fork 123 for carrying a material component 3, the points of action of the supporting force on the mobile fork 123 enclose a force area one, and the center of gravity of the material component 3 falls within the force area one; a conveying member 4 for conveying the material component 3 to the force area one; and a counterweight 2 connected to the supporting component 1, the counterweight 2 and the mobile fork 123 move in the vertical direction at the same time but in opposite directions, and the points of action of the force exerted by the counterweight 2 on the supporting component 1 enclose a force area two, and the projection of the force area two in the vertical direction completely covers the force area one.

[0025] Specifically, the top surface of the mobile fork 123 is used to support the bottom surface of the pallet 32, so that the photovoltaic component 31 applies downward pressure to the mobile fork 123 through the contact area between the pallet 32 ​​and the mobile fork 123, that is, the gravity of the photovoltaic component 31. Secondly, the mobile fork 123 is subjected to a vertical upward supporting force, and the points of action of the supporting force form a force area 1, wherein the gravity action line of the material component 3 passes through the force area 1, and further, its gravity passes through the center of the force area 1, so that the pressure applied by the material component 3 on the mobile fork 123 and the supporting force received by the mobile fork 123 are equal. The bending moment is zero, so that the mobile fork 123 will not undergo flexural deformation when carrying the material component 3, and the top surface of the mobile fork 123 will not undergo bending deformation, so that the contact surface between the material component 3 and the mobile fork 123 is always a horizontal plane, so that the material component 3 will not be subjected to horizontal forces or component forces to cause it to move relative to the mobile fork 123, thereby ensuring that when the mobile fork 123 performs palletizing processing on the material component 3, the pallet 32 ​​will not be offset in the horizontal direction, ensuring that subsequent sub-pallets 32 can be aligned with other sub-pallets 32 and the mother pallet 32.

[0026] Secondly, the conveying member 4 forms a horizontal conveying surface, which conveys the material assembly 3 to the action range of the moving fork 123, so that the gravity action line of the material assembly 3 passes through the force area 1, and then the moving fork 123 extends into the bottom of the pallet 32 ​​to carry the material assembly 3 and lift it for pallet processing.

[0027] Secondly, the counterweight 2 moves downward under the action of gravity, which drives the mobile fork 123 to move vertically upward, and then drives the material component 3 to move upward for combined support processing, wherein the counterweight 2 applies an upward pulling force to the combined support component 1, and the area surrounded by the action points of the pulling force acting on the combined support component 1 is the force area 2, and the planes of the force area 2 and the force area 1 are both horizontal planes, and their projections in the vertical direction are the projections of the tension, pressure, and gravity directions, and their projections can completely cover the force area 1. Furthermore, the center line of the force area 2 passes through the force area 1, so that the tension and pressure bending moment of the combined support component 1 are zero, so that each point in the process of the mobile fork 123 rising rises the same distance, avoiding the top surface of the mobile fork 123 rotating relative to the other side due to only one side being subjected to tension during the rising process, so that the other side rises a different distance, causing the top surface of the mobile fork 123 to change from a horizontal plane to an inclined plane, causing the pallet 32 ​​to shift in the horizontal direction.

[0028] Furthermore, the supporting assembly 1 also includes a supporting member 12 and a chain 13, wherein the supporting member 12 includes a movable fork 123, and both ends of the chain 13 are respectively connected to the supporting member 12 and the counterweight member 2, and the two ends of the chain 13 have opposite movement directions. During the vertical downward movement of the counterweight member 2, the supporting member 12 is driven to move vertically upward by the chain 13.

[0029] Specifically, the supporting member 12 includes a movable fork 123 with a horizontal top surface, and the supporting assembly 1 includes four chains 13, one end of the four chains 13 is respectively connected to the supporting member 12, so that the end can drive the movable fork 123 to move; secondly, the four chains 13 are divided into two groups, one group is connected to the motor through the chain 13 to realize rotation around the sprocket, the rotation of the sprocket drives the transmission shaft to rotate, and then drives the two groups of chains 13 to rotate around the sprocket, realizing the synchronous rotation of the four chains 13, thereby driving the top surface of the supporting member 12 to move the same distance at each point during the rising process, thereby driving the top surface of the movable fork 123 to always be a horizontal plane.

[0030] Secondly, one end of the two chains 13 of the same transmission shaft is respectively connected to the two ends of the same counterweight 2, and the other end thereof is respectively connected to the supporting member 12 by bolts. The connection point applies tension to the supporting member 12. The connection point is the point of application of the tension, and the area enclosed by it is the force area two. The counterweight 2 moves downward, and cooperates with the motor to drive the chain 13 to move around the sprocket, thereby changing the movement direction of the other end of the chain 13 to vertical upward movement, and then the four chains 13 simultaneously drive the force-bearing area 2 of the supporting member 12 to move vertically upward, so that when the motor drives the supporting member 12 to rise for supporting processing, the gravity of the counterweight 2 can offset part of the gravity of the supporting member 12, and then it can reduce the load of the motor, thereby improving the response speed of the motor, so that the motor can change the movement state in time, and then more conveniently lift the supporting member 12 for supporting processing; secondly, the counterweight 2 can absorb part of the vibration generated by the rotation of the motor by applying a force to the chain 13, thereby reducing part of the vibration transmitted to the supporting member 12 through the chain 13, and reducing the impact of the vibration on the material component 3 on the supporting member 12; secondly, the two groups of counterweights 2 act on the two groups of chains 13 at the same time, so that the supporting member 12 can rise faster and improve the supporting efficiency.

[0031] Combination Figure 3 and Figure 4 As shown, the supporting member 12 also includes: a mounting frame 121, the top surface of which is a horizontal plane; a fork rail 122 connected to the top surface of the mounting frame 121, the top surface of which is a horizontal plane connected to a moving fork 123, the moving fork 123 moves relative to the material component 3 along the length direction of the fork rail 122, the fork rail 122 applies a supporting force to one end of the moving fork 123; and a supporting roller 124 connected to the top surface of the mounting frame 121, the supporting roller 124 can apply a supporting force to the other end of the moving fork 123 away from the fork rail 122, and the points of action of the supporting force applied by the fork rail 122 and the supporting roller 124 to the moving fork 123 form a force area 1.

[0032] Specifically, the mounting frame 121 is connected by channel aluminum to form a rectangular frame connecting the fork rails 122 and the support rollers 124. Among them, the mounting frame 121 is connected by at least two fork rails 122 by bolts, and the top surface of the fork rails 122 forms sliding friction with the bottom surface of the moving fork 123. Driven by the chain 13, cylinder and other power parts, the moving fork 123 extends along the fork rails 122 into the bottom of the pallet 32 ​​to carry the material assembly 3 and provide an upward support force, so that the moving fork 123 carrying the material assembly 3 exerts downward pressure on the fork rails 122, and the material assembly 3 exerts downward pressure on the moving fork 123; secondly, after the moving fork 123 is fully extended into and extended from the bottom of the pallet 32 The top end will contact the support roller 124 fixedly connected to the opposite side away from the fork guide rail 122, so that the side surface of the support roller 124 is tangent to the bottom surface of the mobile fork 123, thereby exerting an upward supporting force on the top of the mobile fork 123, wherein the point of action of the support force of the support roller 124 on the mobile fork 123 and the point of action of the support force of the fork guide rail 122 on the mobile fork 123 form a force area 1, so that the total bending moment of the supporting force and pressure acting on the mobile fork 123 is zero, so that the mobile fork 123 will not undergo flexural deformation during the process of carrying the material component 3, thereby affecting the flatness of its top surface.

[0033] Among them, the top surface of the fork guide rail 122 and the top surface of the movable fork 123 are both horizontal planes, so that the top surface of the movable fork 123 is always horizontal during the movement, and the bottom surface of the pallet 32 ​​is always horizontal during the pallet combination processing, so that when the sub-pallet 32 ​​is subsequently stacked on the mother pallet 32, the relative position can be aligned to achieve precise alignment and form a regular material component 3.

[0034] Furthermore, the support assembly 1 also includes a vertical guide rail 14, the length direction of the vertical guide rail 14 is the vertical direction, and when the counterweight 2 moves along the vertical guide rail 14, the chain 13 drives the mounting frame 121 to move along the vertical guide rail 14. The number of vertical guide rails 14 is the same as that of the chain 13, and the points of action of the vertical force applied by the chain 13 to the mounting frame 121 form a force area 2.

[0035] Specifically, the counterweight 2 is slidably connected to the vertical guide rail 14, so that the movement direction of the counterweight 2 is always in the vertical direction during the movement, so that the pulling force applied by the two groups of counterweights 2 to the chain 13 is their own weight; secondly, both ends of the counterweight 2 are slidably connected to the vertical guide rail 14, so that the two ends of the counterweight 2 respectively connected to the chain 13 are subjected to the same vertical friction force, so that the movement speeds of the two ends of the counterweight 2 and the chain 13 are the same, and so their movement distances are the same.

[0036] Secondly, the chain 13 is fixedly connected to the mounting frame 121 through a connecting piece, and the action point of the chain 13 on the mounting frame 121 is the connection point with the mounting frame 121, forming a force area 2, which completely covers the force area 1 so that when the chain 13 lifts the supporting member 12, the bending moment of the supporting member 12 on the chain 13 is zero, and the bending moment of the material component 3 on the supporting member 12 is zero.

[0037] Furthermore, the counterweight 2 includes: a first counterweight 21 connected to the chain 13 at both ends, rollers 23 are provided at both ends of the first counterweight 21 and are slidably connected to the vertical guide rail 14, and the first counterweight 21 can drive the connection point between the mobile fork 123 and the fork guide rail 122 to move vertically upward; and a second counterweight 22 connected to the chain 13, rollers 23 are provided at both ends of the second counterweight 22 and are slidably connected to the vertical guide rail 14, and the second counterweight 22 can drive the support roller 124 to move vertically upward, and the weight of the second counterweight 22 is equal to the weight of the first counterweight 21.

[0038] Specifically, the first counterweight 21 and the second counterweight 22 offset the pulling force of the support 12 on the chain 13 through their own gravity, and then cooperate with the motor to drive the mounting frame 121 to move vertically upward. The same weight of the two makes the pulling force applied to the two groups of chains 13 the same, and then the forces applied to the rotating shaft of the motor through the sprockets by the two groups of chains 13 are the same, so that the rotating shaft of the motor is balanced and the shear force is the same, keeping the position fixed, thereby ensuring that the distance between the two groups of chains 13 and the motor is fixed, so that the tension of the two groups of chains 13 is the same, and then the torque transmitted to the two groups of chains 13 by the motor is the same.

[0039] Furthermore, the first counterweight 21 and the second counterweight 22 are both composed of a plurality of weight blocks of the same specification.

[0040] Specifically, the first counterweight 21 and the second counterweight 22 adjust the number of weight blocks according to the weight of the supporting member 12 and the material assembly 3, and then adjust their own gravity, and then adjust the pulling force on the chain 13, thereby ensuring the load stability of the motor and improving the applicability of the motor for supporting members 12 and material assemblies 3 of different weights.

[0041] Furthermore, the angle of the conveying direction of the conveying member 4 relative to the holding member 12 remains unchanged, and the angle of the material assembly 3 relative to the holding member 12 remains unchanged during the conveying process.

[0042] Specifically, the conveying member 4 is placed under the mounting frame 121, and the pallets 32 are transported to the loading position in sequence, and the mobile fork 123 stacks the pallets 32 in sequence. Since the conveying angle remains unchanged, the initial position of the pallet 32 ​​lifted by the mobile fork 123 is the same. Since the top surface of the mobile fork 123 is always a horizontal plane, the relative position of the pallet 32 ​​with the mobile fork 123 does not change during the rising process. As a result, the angle of the pallet 32 ​​relative to the mounting frame 121 is the same during the conveying and stacking processes, thereby improving the stacking accuracy, achieving the alignment of the pallet 32, and obtaining a regular material assembly 3.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
