DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] like Figure 1As shown, an embodiment of the present application discloses a double-layer material cutting and welding machine, including a double-layer loading rack assembly 1 arranged in sequence along the product transportation direction for driving the double-layer material strip to be transmitted forward, a first roll-to-roll welding assembly 2 for welding the front end product of the double-layer material strip, a second roll-to-roll welding assembly 3 for welding the rear end product of the double-layer material strip, a first roll-to-roll cutting assembly 4 for cutting the waste connection of the lower layer material strip, a thrust detection assembly 5, a second roll-to-roll cutting assembly 6 for cutting the waste connection of the upper layer material strip, and a conveying assembly 7 for conveying the product to the next workstation.

[0044] It should be explained that in this production line, the material belt is conveyed forward by the feeding mechanism 8, and the feeding mechanism 8 is a conventional structure, for example, including a pulling claw that can pull the material belt forward and a cylinder that drives the pulling claw to make horizontal and lifting movements.

[0045] Specifically, during operation, the upper material tray 101 and the lower material tray 102 are discharged synchronously, so that the upper material strip and the lower material strip are stacked up and down and conveyed to the first roll-to-roll welding assembly 2, the first roll-to-roll welding assembly 2 presses the front-end products of the upper material strip and the lower material strip, and welds the upper and lower layers of the upper material strip and the lower material strip together through a laser welding machine, and then the products continue to be conveyed to the second roll-to-roll welding assembly 3, the second roll-to-roll welding assembly 3 presses the rear-end products of the upper material strip and the lower material strip, and welds the upper and lower layers of the upper material strip and the lower material strip together through a laser welding machine. The upper and lower layers of products in the belt are welded together, and then the products continue to be conveyed to the first roll-to-roll cutting component 4, which cuts the waste connection of the lower material belt and collects the cut lower waste belt. Then the products continue to be conveyed to the thrust detection component 5 for welding strength detection. After the detection is completed, the products are conveyed to the second roll-to-roll cutting component 6, which cuts the waste connection of the lower material belt to completely separate the products from the material belt. The separated products are transported to the next workstation by the transport component 7.

[0046] This structure can realize fully automatic welding of two layers of products through the design of a double-layer loading rack assembly 1, a first roll-to-roll welding assembly 2, a second roll-to-roll welding assembly 3, a first roll-to-roll cutting assembly 4, a thrust detection assembly 5, a second roll-to-roll cutting assembly 6 and a conveying assembly 7, thereby improving the overall welding efficiency.

[0047] In this embodiment, the double-layer loading rack assembly 1 includes an upper material tray 101 and a lower material tray 102, and an upper material tray driving motor for driving the upper material tray 101 to rotate and a lower material tray driving motor for driving the lower material tray 102 to rotate. An upper material channel 103 and a lower material channel 104 are respectively arranged on the same side of the upper material tray 101 and the lower material tray 102. A grounding wire induction rod 105 is arranged on the upper material channel and the lower material channel 104. When the grounding wire When there is no electrical signal from the sensing rod 105, the upper material tray 101 and the lower material tray 102 rotate to discharge the material, and a waste roll rod collecting rack 106 is provided on one side of the upper material tray 101 and the lower material tray 102, and a winding rod 107 is provided on the waste roll rod collecting rack 106, and a spring 108 is provided between the winding rod 107 and the waste roll rod collecting rack 106, so that the waste paper on the winding rod 107 can abut against the upper material tray 101 or the lower material tray 102.

[0048] It should be explained that current will be given to the upper material channel 103 and the grounding wire induction rod 105. When the material strip in the upper material channel 103 contacts the grounding wire induction rod 105, the upper material channel 103, the grounding wire induction rod 105 and the material strip will form a loop to generate current. Similarly, when the material strip in the lower material channel 104 contacts the grounding wire induction rod 105, the lower material channel 104, the grounding wire induction rod 105 and the material strip will form a loop to generate current.

[0049] Specifically, the upper material belt is installed in the upper material tray 101, and the lower material belt is installed in the lower material belt. The upper material tray driving motor and the lower material tray driving motor drive the upper material tray 101 and the lower material tray 102 to rotate and discharge the material. In the normal discharge process, the material belt will not contact the grounding wire induction rod 105, and the grounding wire induction rod 105 has no electrical signal. The upper material tray driving motor and the lower material tray driving motor continue to work. When the discharge is too long, the material belt will jump up and contact the grounding wire induction rod 105, and the grounding wire induction rod 105 will generate current. At this time, the upper material tray driving motor The motor or the unloading tray driving motor stops working and waits until the grounding wire sensing rod 105 has no current before continuing to work. At the same time, during the unloading process, there is a layer of waste paper on one side of the material belt, and the waste paper will be wound on the winding rod 107. Under the action of the spring 108, the waste paper on the winding rod 107 will always be in contact with the upper material tray 101 or the lower material tray 102. Under the action of friction, the rotation of the upper material tray 101 or the lower material tray 102 will drive the winding rod 107 to rotate together, so that the winding rod 107 can realize the winding of the waste paper.

[0050] In this structure, the grounding wire induction rod 105 is provided to realize automatic material discharge operation, thereby reducing the situation where the material strip is discharged too much or too little. At the same time, the winding rod 107 is provided to realize automatic collection of waste materials.

[0051] In this embodiment, the first roll-to-roll welding assembly 2 and the second roll-to-roll welding assembly 3 both include a welding frame, in which a lower main board 201 and a first lifting cylinder 202 for driving the lower main board 201 to perform lifting movements are arranged, a lower pressure plate 203 and a second lifting cylinder 204 for driving the lower pressure plate 203 to perform lifting movements are arranged above the lower main board 201, a first positioning needle for penetrating into the positioning holes of the two layers of material strips and a lower pressure head for pressing the product are arranged on the lower main board 201, a lower pressure head cooperating with the upper pressure head is arranged at the lower part of the lower pressure plate 203, a hollow portion for exposing the welding position of the product is arranged on the lower pressure plate 203, and also includes a laser welding assembly arranged on the top of the welding frame and a smoke exhaust pipe 205 for discharging welding smoke.

[0052] Specifically, when the material channel moves to the lower main board 201, the first lifting cylinder 202 drives the lower main board 201 to move upward, and the second lifting cylinder 204 drives the lower pressure plate 203 to move downward, so that the part of the product that does not need to be welded is pressed between the upper pressure head and the lower pressure head. At the same time, the first positioning needle passes through the positioning holes of the two layers of material strips, so that the two layers of material strips are accurately positioned. Then the laser welding assembly performs welding operations on the welding points of the two layers of material strips, and the smoke generated during the welding process is discharged by the exhaust pipe 205.

[0053] The roll-to-roll welding assembly of this structure can realize the welding of the upper and lower layers of the structure while accurately positioning, thereby ensuring the welding automation and the accuracy of the welding, and preventing the misalignment of the upper and lower layers of the product.

[0054] In this embodiment, a detection block is disposed on one side of the lower pressing plate 203 , a sensor mounting block is disposed on one side of the lower main board 201 , and a displacement detection sensor 206 is disposed on the sensor mounting block.

[0055] Specifically, after the lower main board 201 and the lower pressure plate 203 have pressed the product, the displacement detection sensor 206 can detect the distance between the lower main board 201 and the lower pressure plate 203, and thus make a judgment by comparing the actual thickness of the two layers of products. If the thickness is inaccurate, it means that dust and other conditions appear on the material strip.

[0056] In this embodiment, the first roll-to-roll cutting assembly 4 and the second roll-to-roll cutting assembly 6 both include a cutting frame, on which a lower mold 401 and an upper mold 402 located above the lower mold 401 are disposed, a first electric cylinder 403 for driving the upper mold 402 to move downward is disposed above the upper mold 402, and a cutter for cutting off the connection end between the product and the waste is disposed at the lower end of the upper mold 402;

[0058] Specifically, when cutting, when the material channel moves to between the lower mold 401 and the upper mold 402, the first electric cylinder 403 drives the upper mold 402 to move downward, and the cutter under the upper mold 402 cuts off the connection between the product and the waste, and the cut waste is discharged through the waste discharge mechanism 404.

[0059] It should be explained that the waste discharge mechanism 404 described above can be a reel, the waste belt is rolled onto the reel in advance, and the waste is reeled by the reel. The above structure can also be designed as a waste discharge pipe, and the waste is sucked away by the waste discharge pipe.

[0061] Specifically, when conducting inspection, the product is supported by the support plate from below, and the elastic upper pressure block 501 descends. Under the action of the third lifting cylinder 507 and the fourth lifting cylinder 508, the upper product is pressed between the elastic lower pressure block and the support plate 502. Then the second electric cylinder 505 drives the inspection rod 504 to extend into the avoidance groove 503 and contact with the lower product, and exert pressure on the lower product. At this time, the detection sensor can detect the thrust at this time, and judge whether the upper product and the lower product are firmly welded at this time by the size of the thrust.

[0066] The variable pitch module includes a variable pitch mounting plate 712, a suction cup fixing plate 713 is arranged in the middle of the bottom of the variable pitch mounting plate 712, side plates 714 horizontally slidingly connected to the variable pitch mounting plate 712 are arranged on both sides of the suction cup fixing plate 713, and also includes a plurality of connecting rods 715, one end of the connecting rod 715 is rotatably connected to the side plate 714, and the other end of the connecting rod 715 is rotatably connected to the suction cup fixing plate 713, one end of the connecting rod 715 is located below the suction cup fixing plate 713 and is provided with a suction cup 716 for sucking products, and one side of the end of the side plate 714 is provided with a side plate driving cylinder 717 for driving the side plate 714 to make horizontal movements.

[0067] Specifically, when the second roll-to-roll cutting assembly 6 completes cutting of the product, the horizontal driving module drives the material receiving bottom plate 701 to move to the bottom of the second roll-to-roll cutting assembly 6, and the fourth lifting cylinder 702 drives the material receiving bottom plate 701 to rise, so that the cut product can fall on the material receiving bottom plate 701, and through the positioning of the second positioning pin 709, the positioning hole of the product can fall on the second positioning pin 709, and then the first horizontal driving cylinder 707 drives the second material placing rod 705 to move to achieve lateral pitch change of the product, and then the horizontal driving module drives the material receiving bottom plate 701 to move out of the second roll-to-roll cutting assembly 6, the second horizontal driving module 711 drives the spacing frame 710 to move to above the material receiving bottom plate 701, the suction cup 716 sucks up the product in turn and moves it back to its original position, and then the side plate driving cylinder 717 drives the side plate 714 to move horizontally, so that the connecting rod 715 moves, and then the connecting rod 715 drives the suction cup 716 to rotate 90 degrees.

[0068] The transport assembly 7 of this structure can realize the transport and distance change of products, thereby ensuring that the products after distance change fall into the subsequent workstations one by one.
