Description

Technical Field

[0001] The utility model relates to the technical field of laminators, in particular to a conveying reflow machine for a photovoltaic component laminator. Background Art

[0002] In the prior art, before the battery assembly is packaged and cured, a surrounding frame needs to be placed on the edge of each assembly to buffer the pressure transition of the curing rubber sheet during curing, so as to solve the undesirable phenomena such as tearing, hollowing, and excessive pressure caused by the difference between the edge and the inside. However, the battery assembly will produce glue overflow during the lamination process, resulting in conveyor belt contamination, which will affect the normal processing of subsequent battery assemblies. Therefore, the company uses pallets instead of frames to solve the glue overflow problem. However, the number of pallets required for assembly line production is huge. In order to reduce the demand for the number of pallets and reduce production costs, the company needs to develop a pallet reflow line to ensure that the pallet is quickly put into use after it is empty. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the shortcomings of the prior art that a large number of trays are required and the production cost is high when laminating battery components, the utility model provides a conveying reflow machine for a photovoltaic component laminating machine.

[0004] The technical solution to be adopted by the utility model to solve its technical problems is: a conveyor reflow machine for a photovoltaic module laminator, comprising a frame arranged below the laminator, the frame is provided with a multi-layer conveyor belt for transmitting trays, the short side walls of the trays are provided with push-pull ears cooperating with the laminator, the output end of the conveyor belt is provided with a driving frame, the driving frame is provided with a plurality of connecting rods corresponding to the positions of each conveyor belt at intervals in the vertical direction, each connecting rod is provided with two limit baffles corresponding to the positions of the push-pull ears, the driving frame is provided with a driving mechanism for driving the limit baffle to approach or move away from the upper surface of the conveyor belt in the vertical direction, the limit baffle is provided with a telescopic rotating motor on the side close to the conveyor belt, and the output end of the telescopic rotating motor is provided with a clamping plate arranged parallel to the limit baffle.

[0005] The reflow machine is installed under the laminator, and is used to return the pallets conveyed from the laminator (empty pallets after the battery components are unloaded) to the loading side of the laminator. The pallet transfer between the reflow machine and the laminator can be done manually or by an automatic lifter (the automatic lifter is related to the company's invention application on "a conveying lift for a photovoltaic module laminator", and has a certain relevance to the invention of this application). In order to ensure that the position of the pallet transported from the reflow machine conveyor belt will not be skewed, a driving frame is set at the end of the conveyor belt, and the driving mechanism controls the position of the driving frame to rise or fall; when the driving frame is in a low position, the two limit baffles on the connecting rod can block the push-pull ears on both sides of the pallet to prevent the pallet from continuing to move; the telescopic rotating motor first drives the clamping plate to rotate and set it vertically downward, and the two vertically set clamping plates apply force to the side walls of the pallet to correct the position of the pallet in the length direction; then the clamping plate is driven to approach the limit baffle, and force is applied to the push-pull ears on both sides of the pallet to correct the position of the pallet in the width direction, so that the pallet will not be skewed when it is output from the reflow machine, which is convenient for the normal operation of the subsequent "automatic lift"; the telescopic rotating motor drives the clamping plate to release the push-pull ears and then rotate to a horizontal state, and the driving mechanism controls the position of the driving frame to rise, so that the limit baffle is set above the pallet, thereby transporting the pallet to the "automatic lift".

[0006] Furthermore, the driving mechanism includes two hydraulic cylinders arranged at the bottom of the driving frame and guide shafts arranged at both sides of the driving frame, and the driving frame is provided with a plurality of guide wheels matched with the guide shafts. The hydraulic cylinder is used to drive the position of the driving frame to rise and fall, and the arrangement of the guide wheels and the guide shafts ensures that the driving frame is always arranged in a vertical direction without being skewed.

[0007] Furthermore, a guide slope that cooperates with the pallet is provided on one side of the two limit baffles on the same connecting rod, and the distance between the two limit baffles is slightly greater than the length of the pallet. The distance between the limit baffles is slightly greater than the length of the pallet to prevent the pallet from being stuck between the two limit baffles. The guide slope cooperates with the pallet to guide the position of the pallet.

[0008] Furthermore, the distance between the two clamping plates on the same connecting rod in a vertical state is the same as the distance between the two limit baffles.

[0009] Furthermore, a buffer pad is provided on one side of the clamping plate close to the limit baffle.

[0010] The beneficial effects of the utility model are as follows: the utility model provides a conveying reflow machine for a photovoltaic module laminator, which adopts a reflow machine arranged under the laminator to reflow the pallet, and the position of the pallet is corrected by cooperating with a limit baffle and a clamping plate, so that the pallet can be quickly put into use when it is conveyed to the loading side of the laminator, thereby improving production efficiency.

[0016] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0017] like Figure 1-3 As shown, the utility model is a conveyor reflow machine for a photovoltaic module laminator, comprising a frame 1 arranged below the laminator, the frame 1 being provided with a multi-layer conveyor belt 2 for transmitting a tray 3, the short side wall of the tray 3 being provided with a push-pull ear 31 cooperating with the laminator, the output end of the conveyor belt 2 being provided with a driving frame 4, the driving frame 4 being provided with a plurality of connecting rods 5 corresponding to the position of each conveyor belt 2 at intervals in the vertical direction, each connecting rod 5 being provided with two limit baffles 6 corresponding to the position of the push-pull ear 31, the driving frame 4 being provided with a driving mechanism for driving the limit baffle 6 to approach or move away from the upper surface of the conveyor belt 2 in the vertical direction, the limit baffle 6 being provided with a telescopic rotating motor 7 on the side close to the conveyor belt 2, the output end of the telescopic rotating motor 7 being provided with a clamping plate 8 arranged parallel to the limit baffle 6.

[0018] The driving mechanism includes two hydraulic cylinders 9 arranged at the bottom of the driving frame 4 and guide shafts 10 arranged at both sides of the driving frame 4. The driving frame 4 is provided with a plurality of guide wheels 11 cooperating with the guide shafts 10.

[0019] A guide slope cooperating with the tray 3 is provided on one side of the two limit baffles 6 on the same connecting rod 5 , and the distance between the two limit baffles 6 is slightly larger than the length of the tray 3 .

[0020] The distance between the two clamping plates 8 on the same connecting rod 5 in a vertical state is the same as the distance between the two limit baffles 6 .

[0021] A buffer pad is provided on one side of the clamping plate 8 close to the limit baffle 6 .

[0022] Working process:

[0023] The output ends of the two hydraulic cylinders 9 contract to put the drive frame 4 in a low position. When the conveyor belt 2 transports the pallet 3 to the output end, the two limit baffles 6 on the connecting rod 5 can block the push-pull ears 31 on both sides of the pallet 3 to prevent the pallet 3 from continuing to move; the telescopic rotary motor 7 first rotates to drive the clamping plate 8 to rotate and set it vertically downward, and the two vertically set clamping plates 8 apply force to the side walls of the pallet 3 to correct the position of the pallet 3 in the length direction; the output end of the telescopic rotary motor 7 then contracts to drive the clamping plate 8 to move closer to the limit baffle 6, and by applying force to the push-pull ears 31 on both sides of the pallet 3, the position of the pallet 3 in the width direction is corrected, so that the pallet 3 will not be skewed when it is output from the reflow machine;

[0024] After the position correction of pallet 3 is completed, the telescopic rotating motor 7 drives the clamping plate 8 to release the push-pull ear 31 and rotate to a horizontal state. The output end of the hydraulic cylinder 9 extends out to drive the frame 4 to rise, so that the limit baffle 6 is set above the pallet 3, and the pallet 3 enters the "automatic lifting machine" under the transportation of the conveyor belt 2.
