DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Photovoltaic module pallet stacker, such as Figures 1 to 4 As shown, it includes two symmetrically arranged brackets 1, the tops of the brackets 1 are connected by a cross bar 2, and the left and right sides of the brackets 1 are respectively provided with a first clamping mechanism 3 for clamping the two sides of the pallet, and the bottom center of the bracket 1 is respectively provided with a second clamping mechanism 4 for clamping the pallet and a lifting mechanism 5 for lifting the pallet, the second clamping mechanism 4 is connected to the lifting mechanism 5, and the first clamping mechanism 3 is located above the second clamping mechanism 4, and a control cabinet 6 is provided on one of the brackets 1, and a PLC controller is provided inside the control cabinet 6, and the output ends of the PLC controller are respectively connected to the controlled ends of the first clamping mechanism 3, the second clamping mechanism 4 and the lifting mechanism 5.

[0022] The first clamping mechanism 3 includes a first top plate 7, and the inner side of the first top plate 7 is provided with a first support block 8 that is matched with the side holes on the left and right sides of the pallet. The outer side of the first top plate 7 is connected to the first cylinder 9 installed on the bracket 1, and the controlled end of the first cylinder 9 is connected to the output end of the PLC controller in the control cabinet 6.

[0023] A proximity switch for detecting the position of the tray is provided on the first supporting block 8 , and an output end of the proximity switch is connected to an output end of the PLC controller.

[0024] The first top plate 7 is symmetrically provided with a first guide post 10 , which is slidably fitted with a first sleeve 11 mounted on the bracket 1 , and can ensure the stability of the movement of the first top plate when the first cylinder pushes the first top plate to move.

[0025] The second clamping mechanism 4 includes a second top plate 12, which is slidably fitted with a connecting plate 15, and the connecting plate 15 is installed on the lifting mechanism 5. The inner side of the second top plate 12 is provided with a second support block 13 that is fitted with the side holes on the left and right sides of the pallet. The outer side of the second top plate 12 is connected to a second cylinder 19 installed on the connecting plate 15, and the controlled end of the second cylinder 19 is connected to the output end of the PLC controller in the control cabinet 6.

[0026] The second top plate 12 is symmetrically provided with second guide posts 18 , which are slidably fitted with the second sleeve 14 mounted on the connecting plate 15 , thereby ensuring the stability of the movement of the second top plate 12 .

[0027] The jacking mechanism 5 includes a jacking frame 16 installed in the middle of the connecting plate 15, the jacking frame 16 is connected to a jacking cylinder 17 installed outside the bracket 1, and the controlled end of the jacking cylinder 17 is connected to the output end of the PLC controller.

[0028] The lifting cylinder 17 is mounted on a base 20 at the bottom outside the bracket 1 , and both sides of the base 20 are supported by support columns 21 .

[0029] With the second support block 13 at the lowest end as the initial position, when in use, the pallet is moved between the two brackets 1 by a forklift, and then the second cylinder 19 is controlled to drive the second top plate 12 to extend toward the pallet, so that the second support blocks 13 on both sides are respectively inserted and connected with the side holes in the middle of both sides of the pallet.

[0030] Next, the lifting cylinder 17 is started to move, the lifting frame 16 is lifted, and the pallet is driven to move upward.

[0031] When the proximity switch on the first supporting block 8 receives the signal, it sends a signal to the PLC controller to control the lifting cylinder 17 to stop moving.

[0032] At the same time, the first cylinder 9 is controlled to push the first top plate 7 to move toward the pallet, so that the first support block 8 is plugged and connected with the side holes on both sides of the pallet to clamp the pallet.

[0033] Then, the lifting cylinder 17 is controlled to drive the second clamping mechanism to move downward, and the pallet is lifted again according to the above operation to perform pallet stacking.

[0034] During the operation, when the top of the lower pallet contacts the bottom of the upper pallet after lifting, the first clamping mechanism 3 releases the clamping of the pallet, and the upper pallet is driven upward by the lifting mechanism 5. Since the second clamping mechanism clamps the bottom pallet, the stability of the pallet can be guaranteed.

[0035] When the proximity switch on the first support block 8 receives the arrival signal of the bottom pallet, the first clamping mechanism 3 is controlled again to clamp the bottom pallet, and the above operation is repeated to complete the pallet stacking.

[0036] The utility model provides a photovoltaic component pallet stacker, which can quickly and neatly stack photovoltaic component pallets by coordinating a first clamping mechanism, a second clamping mechanism and a lifting mechanism that are staggered in the upper and lower positions, thereby improving the stacking efficiency and ensuring the stability of the pallets after stacking. In addition, the entire device is automatically controlled by a PLC controller, reducing labor costs.
