The head of the head material belt 15 passes through the head material guide wheel 108 and the two stop bars 109 in sequence and enters the head material positioning module 2. The head material belt 15 can be limited by the two stop bars 109.

[0077] According to one embodiment of the present invention, the head material positioning module 2 includes: a positioning module mounting plate 204, and a head material straightening component 205, a head material guiding component 203, a head material positioning component 202 and a welding claw 201 arranged sequentially on the positioning module mounting plate 204 along the conveying direction of the head material belt 15.

Thus, when the head material belt 15 is conveyed between the first positioning block 2022 and the second positioning block 2025, the guide rod cylinder 2021 drives the first positioning block 2022 to approach the head material belt 15, and the head material positioning cylinder 2023 drives the second positioning block 2025 to approach the head material belt 15, until the positioning pin 13 on the second positioning block 2025 is inserted into the positioning hole 14 and extends into the clearance groove. The first positioning block 2022 and the second positioning block 2025 are clamped on both sides of the head material belt 15 to stabilize the head material belt 15. At this time, the head material belt 15 is in the state of waiting to be cut, ensuring the cutting accuracy of the head material belt 15.

[0087] A gripper slide cylinder 207 is mounted on the positioning module mounting plate 204. A pneumatic finger 208 is mounted on the moving end of the gripper slide cylinder 207. The gripper slide cylinder 207 is used to control the pneumatic finger 208 to rise and fall along the z-axis. A welding gripper 201 is mounted on the pneumatic finger 208. The pneumatic finger 208 is used to control the welding gripper 201 to grip the head material strip 15 and the tail material strip 16. Specifically, the welding gripper 201 includes a first gripper and a second gripper that are spaced apart. A laser channel is formed between the first gripper and the second gripper for the laser to pass through. The first gripper is used to grip the head material strip 15, and the second gripper is used to grip the tail material strip 16. The laser cutting and welding module 7 emits a laser into the laser channel, thereby performing butt welding on the head material strip 15 and the tail material strip 16.

[0088] According to one embodiment of the present invention, a buffer module 3 is provided between the feeding module 1 and the head material positioning module 2. The buffer module 3 includes a buffer tray 301 and a detection rod 302. The feeding module 1 and the buffer tray 301 are staggered in height. The detection rod 302 is disposed in the buffer tray 301 and is used to sense the head material strip 15 falling on the detection rod 302. Since the feeding module 1 and the buffer tray 301 are staggered in height, when the detection rod 302 senses the head material strip 15, it means that the head material strip 15 has fallen. If the material enters the buffer tray 301, it indicates that the feeding speed of the feeding module 1 is too fast or the feeding speed of the traction component 501 is too slow. At this time, the control system can adjust the feeding speed of the feeding module 1 or the feeding speed of the traction component 501 in a timely manner according to the feedback of the detection rod 302, so that the material belt remains suspended in the air during the conveying process. This can effectively prevent the material belt from falling into the buffer tray 301 and damaging the terminals due to friction with the buffer tray 301 during the conveying process, thereby improving the stability of the material belt conveying and the product quality.

[0089] The operation of the feeding unit includes the following steps:

[0090] Step S1: Loading the material tray, loading the feeding tray 104 containing a roll of terminal material tape onto the feeding tray motor 105, and loading the empty paper tray 102 onto the paper tray motor 103.

[0091] Step S2: The operator pulls out the head material strip 15 from the end of the feeding tray 104, passing it sequentially through the head material guide wheel 108, between the two stop bars 109, above the buffer module 3, between the two straightening wheels 2051, between the first fixed guide wheel 2031 and the first moving guide wheel 2032, the fiber optic through-beam sensor 2035, between the second fixed guide wheel 2033 and the second moving guide wheel 2034, and between the first positioning block 2022 and the second positioning block 2025 until it extends a certain distance beyond the end of the welding claw 201 (it should be noted that at this time the welding claw 201 is in the initial state, that is, the claw slide cylinder 207 does not control the welding claw 201 to rise). Then, the isolation paper used to separate the two adjacent head material strips 15 is pulled out from the end of the feeding tray 104, passing sequentially through the paper strip guide wheel group 106 and the damper 107 and wrapped around the paper tray 102.

[0092] Step S3: The guide rod cylinder 2021 drives the first positioning block 2022 to approach the head material belt 15, and the head material positioning cylinder 2023 drives the second positioning block 2025 to approach the head material belt 15 until the positioning pin 13 on the second positioning block 2025 is inserted into the positioning hole 14 and extends into the clearance groove. The first positioning block 2022 and the second positioning block 2025 are clamped on both sides of the head material belt 15.

[0093] Step S4: Repeat steps S1 to S2 to complete the material preparation work for multiple feeding units layer by layer.

[0094] The cutting and welding unit is located on one side of the feeding unit. The cutting and welding unit includes: a z-axis linear module 4, a tail material traction module 5, a camera module 6, and a laser cutting and welding module 7.

The tail material traction module 5 is set on the x-axis slide 404. The end of the tail material traction module 5 is equipped with a traction component 501 for guiding and conveying the tail material strip 16 along the x-axis direction.

The second x-axis linear module 403 is used to control the laser cutting and welding module 7 to move along the x-axis direction and to cut and weld the head material strip 15 and the tail material strip 16.

[0095] According to one embodiment of the present invention, the tail material traction module 5 includes: a traction module mounting plate 503, and a tail material positioning component 502, a tail material guiding component 504, and a traction component 501 arranged sequentially on the traction module mounting plate 503 along the conveying direction of the tail material belt 16.

The piston end of the tail material positioning cylinder 5021 faces the tail material belt 16. The third positioning block 5022 is mounted on the piston end of the tail material positioning cylinder 5021. A positioning pin 13 is provided on the side of the third positioning block 5022 facing the tail material belt 16. A positioning hole 14 matching the positioning pin 13 is opened on the tail material belt 16. The tail material positioning cylinder 5021 is used to drive the third positioning block 5022 closer to or further away from the tail material belt 16. The third positioning block 5022 is located on one side of the tail material belt 16. A fourth positioning block 5023 is located on the other side of the tail material belt 16. The third positioning block 5022 corresponds to the fourth positioning block 5023. The fourth positioning block 5023 is provided with a clearance groove for avoiding the positioning pin 13. Thus, when the tail material belt 16 is conveyed between the third positioning block 5022 and the fourth positioning block 5023, the tail material positioning cylinder 5021 drives the third positioning block 5022 to approach the tail material belt 16 until the positioning pin 13 on the third positioning block 5022 is inserted into the positioning hole 14 and extends into the clearance groove. The third positioning block 5022 and the fourth positioning block 5023 are clamped on both sides of the tail material belt 16 to stabilize the tail material belt 16. At this time, the tail material belt 16 is in the state of waiting to be cut, ensuring the cutting accuracy of the tail material belt 16.

Specifically, a plurality of positioning pins 13 are provided on the outer periphery of the third movable guide wheel 5042, and positioning holes 14 that match the positioning pins 13 are opened on the tail material belt 16. The positioning holes 14 are used to... The positioning pin 13, in conjunction with the positioning pin, positions the tail material belt 16 during the conveying and guiding process, thereby improving the conveying accuracy of the belt. Furthermore, the positioning pin 13, through the positioning hole 14, can stabilize the tail material belt 16. It should be noted that multiple positioning pins 13 are arranged in a ring array on the outer periphery of the lower end of the third moving guide wheel 5042, and an annular clearance groove is provided on the outer periphery of the lower end of the third fixed guide wheel 5041. When the positioning pin 13 is inserted into the positioning hole 14, it extends into the annular clearance groove without causing interference.

[0098] The traction assembly 501 includes: a traction wheel 5011, a traction servo motor 5012, and a main traction wheel 5013 mounted on the traction servo motor 5012. The traction wheel 5011 and the main traction wheel 5013 are located on both sides of the tail material belt 16. The traction wheel 5011 and the main traction wheel 5013 are rolledly connected to the tail material belt 16. A plurality of positioning pins 13 are also provided on the outer periphery of the main traction wheel 5013. Specifically, the plurality of positioning pins 13 are arranged in a ring array on the outer periphery of the main traction wheel 5013. An annular clearance groove for avoiding the positioning pins 13 is provided on the outer periphery of the traction wheel 5011.

[0099] The tail material guiding assembly 504 further includes: a first guide plate 5043 and a second guide plate 5044. The first guide plate 5043 is disposed outside the traction wheel 5011, and the second guide plate 5044 is disposed outside the main traction wheel 5013. A tail material channel 5045 for the tail material belt 16 to pass through is formed between the first guide plate 5043 and the second guide plate 5044. The first guide plate 5043 and the second guide plate 5044 are each provided with a second waist-shaped hole 5046. The installation position of the first guide plate 5043 and the second guide plate 5044 on the traction module mounting plate 503 is adjusted by the second waist-shaped hole 5046, thereby achieving the function of adjusting the spacing of the tail material channel 5045, which can adapt to tail material belts 16 of different thicknesses.

[0100] The third moving guide wheel 5042 and the driven traction wheel 5011 are respectively mounted on a second guide wheel adjustment assembly 505. The second guide wheel adjustment assembly 505 includes: a second adjustment guide rail 5051, a second adjustment slider 5052, and a second adjustment rod 5053.

[0101] According to one embodiment of the present invention, the camera module 6 includes: a light source 601 that can be raised and lowered along the z-axis, and a lens 602 and a camera 603 connected as a whole. The light source 601 is located on one side of the head material strip 15 and the tail material strip 16, and the lens 602 and the camera 603 are located on the other side of the head material strip 15 and the tail material strip 16. The camera module 6 detects the size, position and appearance of the head material strip 15 and the tail material strip 16, and transmits the signal to the control system. The control system controls the laser cutting and welding module 7 to work, and cuts the tail of the head material strip 15 and the head of the tail material strip 16, so that the head and tail materials keep the edges neat and improve the welding effect. Specifically, a lifting cylinder 604 is provided on the mobile platform 401, and a light source 601 is installed on the lifting end of the lifting cylinder 604. When the camera module 6 is working, the light source 601 is raised, and together with the lens 602 and the camera 603, it takes pictures and detects the head material belt 15 and the tail material belt 16. When the laser cutting and welding module 7 is working, the light source 601 is lowered to avoid blocking the laser and to protect the light source 601.

[0102] According to one embodiment of the present invention, the laser cutting and welding module 7 includes: a manual platform 701 and a laser assembly 702. The manual platform 701 is mounted on the moving end of a second x-axis linear module 403. The second x-axis linear module 403 is used to control the position of the manual platform 701 in the x-axis direction to realize the cutting operation of the tail material strip 16, the cutting operation of the head material strip 15, or the welding operation of the tail material strip 16 and the head material strip 15. The laser assembly 702 is mounted on the manual platform 701, and the manual platform 701 is used to adjust the position of the laser assembly 702 in the y-axis direction.

[0103] According to one embodiment of the present invention, the manual platform 701 includes:

[0104] Platform base 703 is slidably mounted on the moving end of the second x-axis linear module 403, and a guide rail 704 is provided on the platform base 703 along the y-axis direction;

[0105] The third adjusting slider 705 is mounted on the guide rail 704, and the laser assembly 702 is mounted on the third adjusting slider 705;

[0106] An adjusting screw 706 is provided, with an adjusting turntable 707 mounted at one end. The other end of the adjusting screw 706 extends along the y-axis and is threadedly connected to a third adjusting slider 705. A locking handle 708 is provided on one end of the adjusting screw 706. Specifically, the locking handle 708 includes a locking block 709 and a handle 710. The locking block 709 is sleeved on the adjusting screw 706, and a groove 711 is formed on one end of the locking block 709, dividing the locking block 709 into an upper locking part 712. The handle 710 passes through the groove 711 from the upper locking part 712 and extends into the lower locking part 713. The handle 710 is threadedly connected to both the upper locking part 712 and the lower locking part 713. When the operator rotates the adjusting screw 706 to adjust the third adjusting slider 705 to the set position, rotating the handle 710 will bring the upper locking part 712 and the lower locking part 713 closer together, thereby clamping the adjusting screw 706 and preventing the adjusting screw 706 from rotating, thus locking the third adjusting slider 705.

[0107] According to one embodiment of the present invention, the laser assembly 702 includes: a laser galvanometer 7021, a laser 7022, a field lens 7023, and a light-blocking protective plate 7024 that can be raised and lowered along the z-axis. The laser galvanometer 7021 is mounted on a manual platform 701. The laser 7022 is mounted at the light-incident end of the laser galvanometer 7021. The laser 7022 is used to generate a laser beam. The laser galvanometer 7021 is used to change the propagation direction of the laser beam. The field lens 7023 is mounted at the light-outceasing end of the laser galvanometer 7021. The field lens 7023 is used to converge the laser beam. The field lens 7023 is located on one side of the head feed belt 15 and the tail feed belt 16. The light-blocking protective plate... 7024 is located on the other side of the head material belt 15 and the tail material belt 16, and between the camera module 6 and the field lens 7023. A light-blocking plate lifting cylinder 7025 is provided on the moving platform 401. The light-blocking plate 7024 is installed on the lifting end of the light-blocking plate lifting cylinder 7025. The light-blocking plate lifting cylinder 7025 is used to adjust the position of the light-blocking plate 7024 in the z-axis direction. When the laser assembly 702 is working, the light-blocking plate 7024 rises to block the camera module 6 to protect the camera module 6. When the camera module 6 is working, the light-blocking plate 7024 falls to prevent the light path between the interference light source 601 and the camera 603 from propagating. Therefore, by adjusting the position of the third adjusting slider 705 in the y-axis direction, the distance between the field lens 7023 and the tail material strip 16 and the head material strip 15 in the y-axis direction is adjusted, thereby changing the laser cutting intensity. (It should be noted that the principle of this design is that when the distance between the field lens 7023 and the strip is adjusted, the focal point of the laser beam changes. If the distance between the field lens 7023 and the strip is too close, the laser beam may not be able to focus sufficiently, resulting in a decrease in energy density at the focal point and a weakening of the cutting intensity. Conversely, if the distance between the field lens 7023 and the strip is too far, the laser beam may diverge before reaching the strip, similarly resulting in a decrease in energy density at the focal point and a weakening of the cutting intensity. Only when the distance between the field lens 7023 and the strip is adjusted to a suitable position can the laser beam form the best focusing effect on the strip surface, maximizing the energy density at the focal point and thus achieving the best cutting intensity.)

[0108] According to one embodiment of the present invention, a rotatable guide wheel 405 is provided on the end of the mobile platform 401 away from the feeding assembly. The axis of the guide wheel 405 is arranged along the y-axis direction. The guide wheel 405 changes the tail material belt 16 from a vertical setting to a horizontal setting and guides the tail material belt 16 to the next process.

[0109] According to one embodiment of the present invention, a blanking module 8 is provided on the x-axis slide 404. The blanking module 8 includes: a side rail cylinder 801, a three-axis cylinder 802, a lifting block 803, a stepper motor 804, and a blanking fork 805. The piston end of the side rail cylinder 801 moves along the x-axis direction. The three-axis cylinder 802 is mounted on the piston end of the side rail cylinder 801, and the piston end of the three-axis cylinder 802 moves along the z-axis direction. The lifting block 803 is mounted on the three-axis cylinder 801. On the piston end of component 2, a photoelectric sensor 806 is mounted on the side of the lifting block 803 facing the tail material conveyor 16. A stepper motor 804 is mounted on the lifting block 803, and a dropping fork 805 is mounted on the motor shaft of the stepper motor 804. A slot 808 is formed on the dropping fork 805, and a photoelectric baffle 807 is provided on the dropping fork 805 to cooperate with the photoelectric sensor 806. Through the cooperation of the photoelectric baffle 807 and the photoelectric sensor 806, the stepper motor... After the machine 804 drives the unloading fork 805 to rotate, the unloading fork 805 is reset. When the laser cutting and welding module 7 fails to cut the tail of the head material strip 15 or the head of the tail material strip 16, the side rail cylinder 801 is activated, driving the three-axis cylinder 802 to move along the x-axis to a position above the tail of the head material strip 15 or the head of the tail material strip 16. Subsequently, the three-axis cylinder 802 is activated, driving the lifting block 803 to descend along the z-axis until the head material... When the tail end of the head material strip 15 or the head end of the tail material strip 16 enters the slot 808 of the dropping fork 805, the stepper motor 804 starts and drives the dropping fork 805 to rotate clockwise and counterclockwise by a certain angle, so that the tail end of the head material strip 15 or the head end of the tail material strip 16 is subjected to the torsional force applied by the dropping fork 805, and thus separates from the head material strip 15 or the tail material strip 16. By setting the above-mentioned dropping module 8, the auxiliary separation function of the cut material strip is realized.

[0110] According to one embodiment of the present invention, a material discharge channel 9 is provided on one end of the mobile platform 401 near the material feeding component. The material discharge channel 9 is located between the head material positioning module 2 and the tail material positioning component 502.

[0111] According to one embodiment of the present invention, a waste box 17 is provided on the frame 10. The waste box 17 is located below the bottommost head material positioning module 2 and the moving platform 401. The waste box 17 is used to receive the head material or tail material waste that falls through the material drop channel 9.

[0112] The specific steps involved in cutting and welding the unit are as follows:

[0113] Step S5: The operator rotates the adjusting turntable 707 to adjust the position of the third adjusting slider 705 in the y-axis direction. After adjusting the third adjusting slider 705 to the set position according to the specifications or model of the strip to be cut, the locking handle 708 locks the adjusting screw 706 to prevent it from rotating.
