At the same time, the time for manual placement of the unformed sheet is shortened, thereby improving production efficiency.

[0031] When stamping an unformed sheet, the stamping mechanism 2 is started, the stamping motor 201 is started, the output end of the stamping motor 201 drives the crankshaft 202 to rotate, the rotation of the crankshaft 202 drives the crank arm 204 to reciprocate up and down, the reciprocating up and down movement of the crank arm 204 drives the stamping seat 205 to reciprocate up and down, the reciprocating up and down movement of the stamping seat 205 drives the stamping plate 4 to slide up and down outside the guide post 8, the sliding of the stamping plate 4 up and down outside the guide post 8 drives the upper die back plate 1001 to move up and down, the up and down movement of the upper die back plate 1001 drives the upper die core 1002 to move up and down, the downward movement of the upper die core 1002 enters the inside of the lower die core 1004 to stamp the unformed sheet into a formed shape. When the upper die core 1002 moves downward, the stamping sheet pushes the two demolding plates 1102 to rotate inward around the demolding shaft 1101, and the two demolding plates 1102 rotate toward each other around the demolding shaft 1101 to squeeze the return spring 1103. At this time, the sheet is stamped into a U shape. After stamping, when the upper die core 1002 moves upward, the return spring 1103 releases pressure to push the two demolding plates 1102 to rotate outward around the demolding shaft 1101, and the two demolding plates 1102 rotate outward around the demolding shaft 1101 to push the stamped sheet to separate from the upper die core 1002, preventing the stamped sheet from adhering to the upper die core 1002 and causing the stamping of the sheet to fail.

[0032] After the photovoltaic module frame is stamped and formed, the ejecting mechanism 14 is started to push the stamped sheet upward. The electric telescopic rod 1401 is started to contract. The contraction of the electric telescopic rod 1401 drives the two sliding seats 1402 to slide toward each other in the T-shaped sliding groove of the lower die back plate 1003. The sliding of the two sliding seats 1402 toward each other drives one end of the two ejecting rods 1403 to move toward each other. The movement of one end of the two ejecting rods 1403 toward each other drives the other end of the two ejecting rods 1403 to move upward. The upward movement of the other end of the ejecting rod 1403 drives the ejecting seat 1405 to move upward. The upward movement of the ejecting seat 1405 drives the ejecting block 1406 to slide upward in the lower die core 1004. The ejecting block 1406 slides upward to push the stamped photovoltaic module frame upward by a certain distance and then stops. After the sheet is stamped into a U shape, the tops of the two vertical sides of it need to be folded inward again.

[0033] At this time, the support mechanism 15 is started to support the inner side of the stamped plate, and the support motor 1502 is started. The output end of the support motor 1502 drives the support shaft 1504 to rotate, and the rotation of the support shaft 1504 drives the support gear 1503 to rotate. The support gear 1503 is meshed with the tooth grooves on the lower surface of the support rack 1506. The rotation of the support gear 1503 drives the support rack 1506 to slide on the outside of the guide rail 1505. The support rack 1506 slides on the outside of the guide rail 1505 into the U-shaped plate to provide support for the inside of the stamped plate, so as to prevent deformation of the stamped plate when it is bent, which affects the processing quality of the frame of the photovoltaic module.

[0034] The bending mechanism 12 is started to fold the top of the vertical edge of the stamped sheet inward, and the stamping mechanism 2 drives the upper die back plate 1001 to move upward, and the upper die back plate 1001 moves upward to drive the trigger rod 1201 to move upward, and the trigger rod 1201 moves upward to drive the trigger shaft 1208 to move upward. When the trigger shaft 1208 moves to the inclined surface at the lower part of the trigger groove 1209, under the guidance of the trigger groove 1209, the trigger shaft 1208 moves upward to push the sliding sleeve 1202 to slide inward, and the sliding sleeve 1202 slides inward to push the two connecting rods 1203 to slide toward each other in the guide frame 1206, and the connecting rods 1203 slide toward each other. The inner sliding drives the two bending rods 1207 to slide toward each other, and the two bending rods 1207 slide toward each other to stretch the tension spring 1205. The two bending rods 1207 slide toward each other to fold the top of the vertical edge of the processed plate inward. After the photovoltaic module frame is processed and formed, the stamping mechanism 2 drives the upper mold back plate 1001 to move downward, and the downward movement of the upper mold back plate 1001 drives the trigger rod 1201 to move downward. The tension spring 1205 contracts and pulls the two bending rods 1207 to reset. At this time, the bending mechanism 12 is reset. The bending mechanism 12 integrates the processing steps of the photovoltaic module frame into a set of molds, which improves production efficiency and reduces labor and time costs.

[0035] The support motor 1502 is started in reverse again to make the support rack 1506 slide out from the inside of the stamped plate, and the ejection mechanism 14 is started to eject the stamped photovoltaic module frame from the inside of the lower mold core 1004. At this time, the processing of the photovoltaic module frame is completed.

[0036] A method for using a photovoltaic module frame stamping die comprises the following steps: S1. Use a forklift to place the stamping die 10 on the lifting plate 5, push the fixing seat 601 into the T-shaped slide groove, push the fixing seat 601 to contact the upper die back plate 1001 and the lower die back plate 1003, tighten the fixing bolt 602 with a wrench, start the hydraulic telescopic rod 7, adjust the distance between the upper die core 1002 and the lower die core 1004, pull the positioning handle 1301, the positioning handle 1301 slides outward to drive the two positioning rods 1302 to slide outward, place the unformed sheet between the two positioning rods 1302, loosen the positioning handle 1301, and the two positioning rods 1302 slide toward each other to clamp the unformed sheet; S2, start the stamping mechanism 2, the output end of the stamping motor 201 drives the crankshaft 202 to rotate, the rotation of the crankshaft 202 drives the other end of the crank arm 204 to reciprocate up and down, the other end of the crank arm 204 reciprocates up and down to drive the upper mold core 1002 to move up and down, the upper mold core 1002 moves up and down to stamp the unformed sheet, and the reset spring 1103 pushes the two stripping plates 1102 to rotate in opposite directions with the stripping shaft 1101 as the center, to prevent the sheet from sticking to the upper mold core 1002, causing product processing failure; S3, start the ejection mechanism 14, the electric telescopic rod 1401 contracts to drive the other ends of the two ejection rods 1403 to move upward, the other ends of the ejection rods 1403 move upward to drive the ejection block 1406 to slide upward in the lower mold core 1004, start the support mechanism 15, the output end of the support motor 1502 drives the support rack 1506 to slide on the outside of the guide rail 1505, the support rack 1506 slides on the outside of the guide rail 1505, slides into the plate to provide support for the plate; S4, start the punching mechanism 2, the punching mechanism 2 drives the trigger rod 1201 to move upward, the trigger rod 1201 moves upward and drives the two bending rods 1207 to slide toward each other, the two bending rods 1207 slide toward each other to form the photovoltaic module frame, and after the photovoltaic module frame is formed, the support mechanism 15 and the bending mechanism 12 are reset; S5, start the ejection mechanism 14, push the processed photovoltaic module frame upward, take out the processed photovoltaic module frame, and then put in the unformed plate, and then proceed to process the next product.
