[0033] The solder strip cutting equipment of the present invention includes a first pressing mechanism 23 capable of forming a pressing channel 231, and the pressing channel 231 includes a first pressing surface 2111 and a second pressing surface 2212 parallel to each other. When the pressing channel 231 is closed, the first pressing surface 2111 and the second pressing surface 2212 approach and press the solder strip pulled out from the feeding device 1, thereby keeping the portion of the solder strip pressed by the first pressing surface 2111 and the second pressing surface 2212 flat. The first pressing mechanism 23 is moved by the first moving mechanism 6 to move the pressed solder strip to the cutting station, where the cutting device 3 cuts the solder strip into solder sheets. Therefore, the present invention has a high degree of automation and can cut solder sheets with high flatness, which is beneficial to improving the efficiency of solder strip cutting and the yield.

[0034] Specifically, the length of the pressing channel 231 should be greater than or equal to the length of the solder strip transported into the cutting device 3 by the picking device 2 each time, so that the portion of the solder strip entering the cutting device 3 is pressed by the first pressing mechanism 23.

[0035] Please see Figures 2 to 6 Specifically, the first pressing mechanism 23 includes a first pressing module 21 and a second pressing module 63. The second pressing module 63 includes a first support member 222, a second support member 223, and a pressing member 221. The second support member 223 is slidably connected to the first support member 222. The first support member 222 is connected to the first moving mechanism 6. The pressing member 221 is connected to the second support member 223. The pressing member 221 is arranged opposite to the first pressing module 21 to form a pressing channel 231. The material taking device 2 also includes a second moving mechanism 24. The second moving mechanism 24 is used to drive the second support member 223 to move up and down. Under the action of the second support member 223 moving up and down, the pressing member 221 moves closer to or away from the first pressing module 21 to close or open the pressing channel 231.

[0036] The first pressing module 21 has a groove 211 formed on its lower bottom surface, and the upper surface of the pressing member 221 has a protrusion 2211 that can fit into the groove 211. The pressing channel 231 is formed by the groove 211 and the protrusion 2211. The bottom wall of the groove 211 is the first pressing surface 2111, and the upper surface of the protrusion 2211 is the second pressing surface 2212. The second bearing member 223 is connected to the first bearing member 222 through the fourth sliding structure 227.

[0037] Please see Figure 1 , Figure 2 and Figure 8In some embodiments, the cutting device 3 includes a second pressing mechanism 34 and a third pressing mechanism 38, which are used to press the solder strip and can create a height difference between the solder strip portion located in the second pressing mechanism 34 and the solder strip portion located in the third pressing mechanism 38 to cut the solder strip.

[0038] Specifically, the second pressing mechanism 34 and the third pressing mechanism 38 are close to each other. When the second pressing mechanism 34 and the third pressing mechanism 38 press the solder strip and form a high-low displacement difference to cut the solder strip, the cutting surface of the solder strip can be formed between the first pressing mechanism 23 and the second pressing mechanism 34, and the cutting surface can be made flat.

[0039] Please see Figure 1 , Figure 3 , Figure 8 and Figure 9 Specifically, the cutting device 3 also includes a third support member 37 and a third moving mechanism 381 connected to the third support member 37. The third support member 37 is slidably connected to the frame 4. The second pressing mechanism 34 includes a third pressing module 31 and a fourth pressing module 33 arranged opposite to each other.

The third pressing mechanism 38 includes a fifth pressing module 32 and a sixth pressing module 36 respectively connected to the third support member 37. Module 32 is used to press the solder strip portion located on the sixth pressing module 36; the third moving mechanism 381 can drive the third bearing member 37 to move up and down so that the fourth pressing module 33 moves closer to or away from the third pressing module 31 to press or release the solder strip portion located between the third pressing module 31 and the fourth pressing module 33; during the upward movement of the third bearing member 37, the third pressing module 31 stops the fourth pressing module 33 to compress the first elastic member 332, and the solder strip portion pressed by the fifth pressing module 32 and the sixth pressing module 36 continues to rise under the drive of the third bearing member 37 to cut the solder strip.

[0040] Specifically, the third support member 37 is provided with a mounting groove 333, and the side wall of the mounting groove 333 is provided with a fifth sliding structure 331. The fourth pressing module 33 is slidably connected to the side wall of the mounting groove 333 through the fifth sliding structure 331. By setting a first elastic member 332 between the third support member 37 and the fourth pressing module 33, when the third support member 37 drives the fourth pressing module 33 to rise and press the solder strip onto the third pressing module 31, the third support member 37 can still rise by compressing the first elastic member 332 to drive the third pressing mechanism 38 to rise and exceed the height of the second pressing mechanism 34. This results in a height difference between the solder strip portion located in the second pressing mechanism 34 and the solder strip portion located in the third pressing mechanism 38 to cut the solder strip.

[0041] Please see Figure 2 , Figure 5 , Figure 10 and Figure 11 Specifically, the device further includes a drive unit 5. The fifth pressing module 32 includes a first swing member 322 and a second swing member 323 oscillatingly connected to the third support member 37.

The drive unit 5 can drive the first swing member 322 and the second swing member 323 to swing to press or release the solder strip portion located in the sixth pressing module 36. The first swing member 322 and the second swing member 323 are connected to the third support member 37. When the third support member 37 rises, the first swing member 322 and the second swing member 323 can rise synchronously with it, so that the third pressing mechanism 38 remains in a pressed state during the rise.

[0042] Please see Figures 2 to 5 Furthermore, the first moving mechanism 6 includes a first cam 61, a second elastic element 66, a first sliding structure 63, and a first transmission structure.

The first transmission structure includes a first movable element 65, and the first movable element 65 is provided with a first sliding part 64. The first movable element 65 is connected to the first pressing mechanism 23. The first sliding part 64 abuts against the outer peripheral wall of the first cam 61. The driving device 5 can drive the first cam 61 to rotate. Under the rotation of the first cam 61, the first sliding part 64 slides along the outer peripheral wall of the first cam 61, so that the first pressing mechanism 23 slides laterally to approach or move away from the cutting device 3. Under the action of the second elastic member 66, the first sliding part 64 can slide close to the outer peripheral wall of the first cam 61 when the first cam 61 rotates. When the first sliding part 64 slides from the proximal part to the distal part of the first cam 61, the first movable member 65 drives the first pressing mechanism 23 to move from a position away from the cutting device 3 to a position close to the cutting device 3. When the first sliding part 64 moves from the distal part to the proximal part of the first cam 61, the first pressing mechanism 23 moves from a position close to the cutting device 3 to a position away from the cutting device 3.

[0043] Please see Figure 2 and Figure 6In some embodiments, the second moving mechanism 24 includes a second transmission structure and a second sliding structure 243.

The second sliding part 245 supports the second bearing member 223. The driving device 5 includes a second cam 56. The third sliding part 242 abuts against the outer peripheral wall of the second cam 56. Driving the second cam 56 to rotate can cause the third sliding part 242 to slide along the outer peripheral wall of the second cam 56 to drive the second movable member 241, the second bearing member 223 and the pressing member 221 to move up and down. By having the second sliding part 245 support the second carrier 223, the second carrier 223 can avoid generating large resistance with the second movable part 241 when it moves laterally. Furthermore, the up-and-down movement of the second movable part 241 can be transmitted to the second carrier 223 through the second sliding part 245, causing the second carrier 223 to move up and down.

The second pressing mechanism 34 releases the solder strip; when the first cam 61, the fourth cam 58 and the fifth cam 59 are rotated by the drive motor 51, the first sliding part 64 slides to the first part 612, the lower end 3221 of the first swing member 322 slides from the seventh part 581 to the eighth part 582, and the lower end 3231 of the second swing member 323 slides from the ninth part 591 to the tenth part 592, the first pressing mechanism 23 presses the solder strip and moves it to the second position close to the cutting device 3, and the third pressing mechanism 38 presses the solder strip; when the drive motor 51 continues to drive the third cam 57 to rotate, the fourth sliding part 38 slides from the fifth part 571 to the sixth part 572, the second pressing mechanism 34 presses the solder strip and forms a high-low displacement difference with the third pressing mechanism 38 to cut the solder strip. After the solder strip is cut, the second cam 56 is driven to rotate by the drive motor 51, causing the third sliding part 242 to slide from the third part 561 to the fourth part 562. At this time, the pressing channel 231 is opened, and the second pressing mechanism 34 remains in a pressing state. Then, the first cam 61 is rotated to make the first sliding part 64 slide from the first part 612 to the first part 611, so that the first pressing mechanism 23 moves from the second position to the first position, thereby cyclically conveying the solder strip into the cutting device 3 and cutting the solder strip.

[0049] The various steps of cutting solder strip are coordinated by the cooperation of the first cam 61, the second cam 56, the third cam 57, the fourth cam 58 and the fifth cam 59, and only one drive motor 51 is used as the power source, which helps to simplify the equipment structure and reduce the size of the equipment. The cooperation of the first cam 61 and the second cam 56 can ensure that the length of the solder strip fed into the cutting device 3 is consistent each time, thereby ensuring that the length of the solder sheet cut off each time is also consistent. By adjusting the cooperation relationship between the first cam 61 and the second cam 56, the length of the solder strip fed into the cutting device 3 can be adjusted. The length of the solder strip fed into the cutting device 3 each time is the moving distance of the second pressing mechanism 34 pressing the solder strip and moving it to the second position.

[0050] Please see 4 and Figure 6Furthermore, the device also includes a fifth elastic element 29 and a sixth elastic element 311. The fifth elastic element 29 is disposed between the first movable element 65 and the second bearing element 223. The fifth elastic element 29 applies a downward force to the second bearing element 223, so that when the second movable element 241 and the second sliding part 245 move downward, the second bearing element 223 abuts against the second sliding part 245 under the elastic force of the fifth elastic element 29 and its own gravity. The sixth elastic element 311 is disposed between the frame 4 and the third bearing element 37. The sixth elastic element 311 applies a downward force to the third bearing element 37, so that the fourth sliding part 38 is tightly attached to the outer peripheral wall of the third cam 57.

[0051] Please see Figure 1 and Figure 2 In some embodiments, the device further includes a feeding groove 41 and a seventh pressing module 42. The feeding groove 41 is recessed in the frame 4 and is used to convey the solder strip pulled from the feeding device 1. The seventh pressing module 42 is rotatably connected to the frame 4 and is in close contact with the solder strip on the feeding groove 41. When the taking device 2 pulls the solder strip, the seventh pressing module 42 can rotate slightly away from the feeding groove 41. The setting of the seventh pressing module 42 can make the solder strip entering the taking device 2 flat.

[0052] Please see Figure 1 In some embodiments, the feeding device 1 includes a connector 11 and a reel 12 rotatably connected to the connector 11. The connector 11 is connected to the frame 4. The reel 12 is wound with solder strip to be cut. When the feeding device 2 pulls the solder strip, the reel 12 rotates to release the solder strip.

[0053] Please see Figure 2 and Figure 11 In some embodiments, the rotating shaft 52 of the drive device 5 is also provided with a positioning disk 54, the positioning disk 54 is provided with a sensing mark 541, and a position sensor 541 is provided corresponding to the positioning disk 54.

[0054] Please see Figure 8 and Figure 9 In some embodiments, the device further includes an optical fiber sensor 7, the transmitting end and the receiving end of which are respectively disposed on both sides of the frame 4. After the cutting device 3 cuts the solder strip, the transmitting end and the receiving end of the optical fiber sensor 7 are blocked by the cut solder strip, thereby sensing whether there is a cut solder sheet on the sixth pressing module 36.

[0055] The first sliding structure 63, the second sliding structure 243, the third sliding structure 35, the fourth sliding structure 227 and the fifth sliding structure 331 in this invention can all be a sliding rail and a slider cooperation structure, or other cooperation structures that can slide against each other.
