[0020] like Figures 1 to 4 As shown, the utility model provides a fully automatic welding strip cutting device, which is used to cut a rolled welding strip 201 into welding sheets, including a mechanism body 202, on which a unwinding mechanism and a conveying rail 204 are arranged, on which a tape roll 203 is installed, and the welding strip 201 is led out from the tape roll 203 and introduced into the conveying rail 204; on the mechanism body 202, clamping mechanisms 205 are sequentially installed along the conveying rail 204, which are used to clamp the welding strip 201 on the conveying rail 204; a spacing mechanism 206 is used to clamp the welding strip 201 and move it laterally; and a cutting mechanism 207 is used to cut off the welding strip 201 fed by the clamping mechanism 205 or the spacing mechanism 206.

[0021] The soldering strip 201 cutting device designed in this patent can cut the rolled soldering strip 201 into soldering pieces of a specified length, and the length of the soldering piece can be adjusted to any length as needed. When soldering pieces of different widths are needed, it is only necessary to replace the soldering strip 201 with the corresponding size and re-cut it.

[0022] The specific operation method is that, during the preparation work, the rolled welding tape 201 is installed on the unwinding mechanism, which is a conventional structure used in common coil processing, and is mainly composed of a combination of guide wheels, buffer wheels, etc. After the welding tape 201 is released from the coil 203, it is introduced into the conveying rail 204 to be flattened. After the clamping mechanism 205 and the spacing mechanism 206 work in sequence to feed the welding tape 201 to a certain length, the cutting mechanism 207 performs the cutting operation.

[0023] The clamping mechanism 205 and the cutting mechanism 207 are in a working mode where one side clamps and the other side releases. This stepping method feeds the soldering strip 201 forward according to the set length. The detailed operation process is as follows: when cutting starts, the clamping mechanism 205 is in a loose state, the spacing mechanism 206 clamps the soldering strip 201 and moves it horizontally to the feeding finger cutting mechanism 207, the cutting mechanism 207 works to cut the soldering strip 201 as the starting end of the soldering strip 201, then the clamping mechanism 205 clamps the soldering strip 201, the spacing mechanism 206 releases the soldering strip 201 and returns to its original position, after completion, the clamping mechanism 205 releases the soldering strip 201 again, the spacing mechanism 206 clamps the soldering strip 201 again and moves forward a specified distance, and then the cutting mechanism 207 cuts the soldering strip 201, so that the soldering strip 201 of the specified length is obtained, and the reciprocating cycle works continuously.

[0024] The conveying rail 204 includes a flat rail 208 and a side rail 209 installed parallel to the upper end surface of the flat rail 208; the clamping mechanism 205 includes a clamping cylinder 210 installed below the flat rail 208, a first clamping plate 211 arranged above the flat rail 208 and a clamping guide portion, the clamping guide portion includes a clamping guide rail 212 vertically fixed on the mechanism body 202, a clamping slider 213 is arranged on the clamping guide rail 212, a clamping bracket 214 is installed on the clamping slider 213, and the clamping bracket 214 is fixedly connected to the first clamping plate 211; the piston rod of the clamping cylinder 210 is fixedly connected to the clamping bracket 214, and the welding strip 201 is passed between the first clamping plate 211 and the flat rail 208.

[0025] The welding strip 201 is mainly flattened and installed on the flat rail 208. The side gauges clamp the two sides of the welding strip 201. The welding strip 201 is laid flat on the conveyor rail 204 and fed forward. The clamping cylinder 210 can drive the first clamping plate 211 to move up and down above the flat rail 208. In this way, the clamping mechanism 205 has the functions of clamping and releasing. When clamping is required, the piston rod of the clamping cylinder 210 retracts, and the first clamping plate 211 presses the welding strip 201 onto the flat rail 208. When releasing is required, the piston rod of the clamping cylinder 210 extends, and the first clamping plate 211 releases the welding piece.

[0026] The clamping guide rail 212 and the clamping slide block 213 mainly play the role of stabilizing the clamping bracket 214, ensuring that the clamping bracket 214 can stably move vertically under the drive of the clamping cylinder 210, thereby improving the stability and reliability of the clamping mechanism 205.

[0027] The spacing mechanism 206 is installed in the flat rail 208, and the spacing mechanism 206 includes a spacing drive part, a spacing cylinder 215 installed on the spacing drive part, a second clamping plate 216 and a spacing movable frame 223 arranged on the piston rod of the spacing cylinder 215; the spacing drive part includes a horizontally arranged spacing drive screw 217, a spacing drive block 218 installed on the spacing drive screw 217 and a spacing drive motor 219, the spacing drive motor 219 rotates to drive the spacing drive block 218 to move along the spacing drive screw 217, and the spacing A distance fixing frame 220 is provided on the driving block 218, the distance cylinder 215 is fixedly installed on the distance fixing frame 220, a distance vertical guide rail 221 is vertically installed on the distance fixing frame 220, a distance vertical slider 222 is installed on the distance vertical guide rail 221, the distance vertical slider 222 is fixedly connected to the distance movable frame 223, the second clamping plate 216 is arranged above the distance movable frame 223 and fixedly connected to the distance fixing frame 220; the welding strip 201 is passed between the second clamping plate 216 and the distance movable frame 223.

[0028] The distance driving part further includes a distance transverse guide rail 224 horizontally mounted on the mechanism body 202 , on which a distance transverse slider 225 is slidably mounted, and the distance transverse slider 225 is fixedly connected to the distance fixing frame 220 .

[0029] The working principle of the distance mechanism 206 is different from that of the clamping mechanism 205. The distance driving motor 219 rotates to drive the distance driving block 218 to move, and the distance driving block 218 drives the entire distance fixing frame 220 to move horizontally, so that it has a distance function. The piston rod of the distance cylinder 215 on the distance fixing frame 220 moves up and down to drive the distance movable frame 223 to move up and down. The second clamping plate 216 is installed on the distance fixing frame 220. In this way, the up and down movement of the distance movable frame 223 is combined with the second clamping plate 216 to form an operation of clamping and releasing the welding strip 201 passing through it. The combination of the distance vertical guide rail 221 and the distance vertical slider 222 and the distance transverse guide rail 224 and the distance transverse slider 225 is to improve the reliability of the moving parts during the transverse and vertical movement process, and improve the operation accuracy and stability of the device.

[0030] The cutting mechanism 207 includes a cutting seat 226, a knife seat 227, a cutter 228 and a cutting drive mechanism. The cutting seat 226 has a vertical cutting surface. A linear material port 229 is horizontally opened on the cutting surface. The welding strip 201 passes through the material port 229. The knife seat 227 is arranged to fit the cutting surface. A slide groove 230 is vertically opened on the knife seat 227. The cutter 228 is slidably installed in the slide groove 230 and is arranged to fit the cutting surface. A spring piece 231 is also arranged on the knife seat 227 to push the cutter 228 toward the cutting surface; the cutting drive mechanism drives the cutter 228 to move up and down along the slide groove 230.

[0031] The cutter 228 slides up and down in the chute 230 in contact with the cutting surface, and can easily cut the welding strip 201 at the material opening 229. This cutting method has a neat fracture and the welding strip 201 is cut off from the material opening 229, and the cutting accuracy can be accurately controlled. The cutter 228 is in a free state in the chute 230 and is pushed by the spring 231 to fit on the cutting surface. This method has self-compensation ability, and there is no need to consider the problem of reduced processing accuracy caused by the wear of the cutter 228.
