[0055] It also includes an L-shaped member feeding mechanism 10 disposed on one side of the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7;

[0056] The L-shaped piece feeding mechanism 10 includes an L-shaped piece feeding assembly 110, an L-shaped piece cutting assembly 120, and a dividing mechanism 130 which divides the L-shaped pieces cut by the L-shaped pieces into the first L-shaped welding assembly 6 and the second L-shaped welding assembly 7 respectively.

[0057] During the specific operation, the main material belt loading component 1 discharges the material, so that the main material belt moves to the first main material belt welding component 2 and the second main material belt welding component 3 in sequence. Then, the external transport component transports the parts to be welded to the first main material belt welding component 2 and the second main material belt welding component 3 for welding operations. Then the product continues to be transported to the roll-to-roll waste cutting component 4, and the roll-to-roll waste cutting component 4 removes the waste on the material belt. Then the product continues to be transported to the first thrust testing component 5, and the first thrust testing component 5 detects whether the upper layer product and the lower layer product are welded firmly. After the detection is completed, the product is transported to The first L-shaped welding component 6 and the second L-shaped welding component 7, the L-shaped part feeding mechanism 10 divides the L-shaped parts into the first L-shaped welding component 6 and the second L-shaped welding component 7 respectively, the main material and the L-shaped parts are welded together by the first L-shaped welding component 6 and the second L-shaped welding component 7, after the welding is completed, the product is conveyed to the L-shaped part breaking component 8, the L-shaped part breaking component 8 breaks the end waste of the L-shaped part, after the breaking is completed, the product continues to be conveyed to the second thrust testing component 9, the second thrust testing component 9 detects whether the upper layer product and the lower layer product are firmly welded, and completes the production of the entire product.

[0058] In this structure, through the coordinated use of the main material strip feeding assembly 1, the first main material strip welding assembly 2, the second main material strip welding assembly 3, the roll-to-roll waste cutting assembly 4, the first thrust testing assembly 5, the first L-shaped welding assembly 6, the second L-shaped welding assembly 7, the L-shaped piece breaking assembly 8, the second thrust testing assembly 9 and the L-shaped piece feeding mechanism 10, full-automatic welding of the product can be achieved, thereby improving the overall welding efficiency.

[0059] In this embodiment, the main material belt loading assembly 1 and the L-shaped piece loading assembly 110 both include a material tray 101 and a material tray driving motor for driving the material tray 101 to rotate, a material channel 102 is provided on one side of the material tray 101, a grounding wire sensing rod 103 is provided on the material channel 102, when there is no electrical signal from the grounding wire sensing rod 103, the material tray 101 rotates to discharge the material, a waste roll rod collecting rack is provided on one side of the material tray 101, a winding rod 104 is provided on the waste roll rod collecting rack, a spring is provided between the winding rod 104 and the waste roll rod collecting rack, so that the waste paper on the winding rod 104 can abut against the material tray.

[0060] It should be explained that current will be given to the material channel 102 and the grounding sensor rod 103. When the material strip in the material channel 102 contacts the grounding sensor rod 103, the material channel 102, the grounding sensor rod 103 and the material strip will form a loop to generate current.

[0061] Specifically, during operation, the material belt is installed in the material tray 101, and the material tray driving motor drives the material tray 101 to rotate and discharge the material. During normal material discharge, the material belt will not contact the grounding wire sensing rod 103, and the grounding wire sensing rod 103 has no electrical signal, and the material tray driving motor continues to work. When the material discharge is too long, the material belt will jump up and contact the grounding wire sensing rod 103, and the grounding wire sensing rod 103 will generate current. At this time, the material tray driving motor stops working and waits for the grounding wire sensing rod 103 to have no current before continuing to work. At the same time, during the material discharge process, there is a layer of waste paper on one side of the material belt, and the waste paper will be wound around the winding rod 104. Under the action of the spring, the waste paper on the winding rod 104 will always be in contact with the material tray 101. Under the action of friction, the rotation of the material tray 101 will drive the winding rod 104 to rotate together, so that the winding rod 104 can realize the winding of the waste paper.

[0062] In this structure, the grounding wire induction rod 103 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 104 is provided to realize automatic collection of waste materials.

[0063] In this embodiment, the first main material strip welding assembly 2 and the second main material strip welding assembly 3 both include a first welding frame, in which a first main flow channel plate 201 for the main material channel 102 to pass through is provided, a first lower pressure block mounting plate 202 and a first lifting drive cylinder 203 for driving the first lower pressure block mounting plate 202 to perform lifting movement are provided below the first main flow channel plate 201, a first upper pressure block mounting plate 204 is provided above the first main flow channel plate 201, a second lifting drive cylinder 205 for driving the first upper pressure block mounting plate 204 to perform lifting movement is provided below the first lifting drive cylinder 203, and a first lower pressure block is provided at the bottom of the first upper pressure block mounting plate 204. The upper surface of the first lower pressure block mounting plate 202 is provided with a first upper pressure block that cooperates with the first lower pressure block, and the upper surface of the first lower pressure block mounting plate 202 is provided with a retractable first part positioning needle 206. The bottom end of the first part positioning needle 206 is provided with a third lifting drive cylinder 207 for driving the first part positioning needle 206 to extend out of the upper surface of the first lower pressure block mounting plate 202. The first lower pressure block mounting plate 202 is also provided with a first material strip positioning needle 208 for positioning the material strip. A notch is opened on the first upper pressure block mounting plate 204 to expose the product welding point, and a first laser welding component 209 for welding is arranged above the first upper pressure block mounting plate 204.

[0064] Specifically, during operation, the main material belt moves to the first main flow channel plate 201, the first part positioning pin 206 is in an extended state, the part is transported to the first lower pressure block mounting plate 202 by an external mechanism, and is positioned by the first part positioning pin 206, then the first lifting drive cylinder 203 drives the first lower pressure block mounting plate 202 to rise, and the second lifting drive cylinder 205 drives the first upper pressure block mounting plate 204 to descend, so that the part and the main material belt are pressed together, and the main material belt is positioned by the first material belt positioning pin 208. At this time, the main material belt and the part are pressed by the first upper pressure block and the first lower pressure block, and the first laser welding assembly 209 welds the main material belt and the part. After welding is completed, the third lifting drive cylinder 207 first drives the first part positioning pin 206 to descend, so that the first part positioning pin 206 exits the product, and then the first lifting drive cylinder 203 drives the first lower pressure block mounting plate 202 to descend, and the second lifting drive cylinder 205 drives the first upper pressure block mounting plate 204 to rise, and the product continues to flow to the next workstation.

[0065] The arrangement of the above structure can realize precise positioning of the main material strip and parts during welding. At the same time, after welding is completed, the third lifting drive cylinder 207 first drives the first part positioning needle 206 to descend, thereby preventing the first part positioning needle 206 from pulling the product skewed when the first lower pressure block mounting plate 202 descends, thereby ensuring the product yield.

[0066] In this embodiment, it also includes a precision positioning pin 210 arranged below the first upper pressure block mounting plate 204, and the first lower pressure block mounting plate 202 is provided with a pin hole that cooperates with the precision positioning pin 210. When the first upper pressure block mounting plate 204 moves downward and the first lower pressure block mounting plate 202 moves upward, the precision positioning pin 210 passes through the main channel plate and extends into the pin hole. A detection block is provided on one side of the first upper pressure plate mounting plate, and a sensor mounting block is provided on one side of the lower pressure plate mounting plate, and a displacement detection sensor 211 is provided on the sensor mounting block.

[0067] Specifically, when the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202 move toward each other, the precision positioning pin 210 can be inserted into the pin hole, thereby ensuring the position of the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202. At the same time, during the movement, the displacement detection sensor 211 can detect the distance between the first upper pressure block mounting plate 204 and the first lower pressure block mounting plate 202. When the detected distance position is inaccurate, it means that the material tape may be stuck at this time, and the material tape needs to be inspected to ensure the yield rate of subsequent product production.

[0068] In this embodiment, the roll-to-roll waste cutting assembly 4 and the L-shaped piece cutting assembly 120 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;

[0069] A waste discharge mechanism 404 for collecting waste is also provided at the bottom end of the cutting frame.

[0070] Specifically, when the cutting operation is performed, when the main material channel 102 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.

[0071] 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.
