[0039] Embodiment 1

[0040] This embodiment provides an automatic cutting system, as Figures 1 to 7 shown, which includes a positioning device 1 and a cutting device 2. Among them, the positioning device 1 has a positioning component for positioning the workpiece to be cut; the cutting device 2 is movably arranged towards or away from the positioning device 1, and its cutting part cooperates with the positioning device 1 to cut the workpiece to be cut when it is on the side of the workpiece to be cut away from the positioning device 1.

[0041] Specifically, the automatic cutting system is suitable for cutting various materials. For example, when the automatic cutting system is used to cut the clip 5, the workpiece to be cut is the clip 5, and the clips 5 are connected in rows at intervals on both sides of the connecting belt 6, and the middle of the connecting belt 6 has a circular through hole.

[0042] As Figure 3 and Figure 7 shown, the feeding device 3 includes two positioning columns 31, a fourth driving mechanism 32, a fifth driving mechanism 33, a first conveying table 34, a transition conveying table 35, a second conveying table 36 and a second connecting plate 234. The driving end of the fourth driving mechanism 32 is connected with an L-shaped plate, and the two positioning columns 31 are arranged on the L-shaped plate. The upper part of the positioning column 31 is conical, which is convenient for inserting into the circular through hole of the connecting belt 6. The fourth driving mechanism 32 is arranged on the third connecting plate 37, and the third connecting plate 37 is connected with the driving end of the fifth driving mechanism 33. The fifth driving mechanism 33 is arranged on the machine frame. For example, both the fourth driving mechanism 32 and the fifth driving mechanism 33 are cylinders.

[0043] During operation, a row of the connecting belt 6 and the clips 5 are placed on the first conveying table 34. The first conveying table 34 is provided with elongated holes. The fourth driving mechanism 32 drives the positioning columns 31 to move upward through the elongated holes and insert into the circular through holes of the connecting belt 6 to position the connecting belt 6 and the clips 5. The fifth driving mechanism 33 drives the fourth driving mechanism 32 towards the positioning device 1 through the third connecting plate 37, so as to drive the positioning columns 31 to slide in the elongated holes and transport the front connecting belt 6 and the clips 5 to the lower part of the positioning device 1. The two positioning columns 31 located on the same straight line simultaneously pull the connecting belt 6 forward to prevent the connecting belt 6 from tilting.

[0044] A cover plate is arranged above the first conveying table 34. The cover plate is provided with a groove facing the first conveying table 34. During operation, the groove is clamped above the connecting belt 6 to play a guiding role, so that the rear connecting belt 6 enters the first conveying table 34 evenly.

[0045] The positioning device 1 includes a positioning component, a first slider 12, a first driving mechanism 13, and a first connecting plate 14. Among them, the positioning component includes a positioning knife 111, an elastic positioning member 112, and an abutting member 113. The first driving mechanism 13 is a cylinder. The driving end of the first driving mechanism 13 is connected to the first slider 12. The first slider 12 is provided with a first special-shaped through hole with a smooth transition in height. The first connecting plate 14 is connected to the first connecting column, and the first connecting column is inserted into the first special-shaped through hole. The first driving mechanism 13 drives the first slider 12 to move horizontally, and the horizontal movement of the first slider 12 drives the first connecting plate 14 to move up and down.

[0046] As Figure 4 shown, two rows of spaced mounting grooves are formed on the first connecting plate 14. Each mounting groove is equipped with a fitting positioning knife 111 and an elastic positioning member 112. The positioning knife 111 is located inside the elastic positioning member 112. The abutting member 113 is sleeved on the connecting column and arranged on the first connecting plate 14. The abutting member 113 is located inside the two rows of positioning knives 111 and is adapted to be clamped above the connecting strip 6.

[0047] As Figure 5 and Figure 6 shown, the cutting device 2 includes a cutting member 21, a support table 22, and a cutting driving mechanism. The cutting driving mechanism includes a second slider 231, a second driving mechanism 232, a third driving mechanism 233, a second connecting plate 234, a third slider 235, and a guide rail 236. Both the second driving mechanism 232 and the third driving mechanism 233 are cylinders.

[0048] There are two sets of the positioning component and the cutting device 2. The two sets of cutting devices 2 are symmetrically distributed on both sides of the positioning device 1. During operation, the clamps 5 on both sides of the connecting strip 6 can be positioned and cut simultaneously, improving production efficiency.

[0049] The support table 22 has a receiving portion for receiving the cut clamps 5. The cutting member 21 is provided on the support table 22 as a cutting portion. The driving end of the second driving mechanism 232 is connected to the second slider 231. The second slider 231 is provided with a second special-shaped through hole 2311 with a smooth transition in height. The support table 22 is inserted into the second special-shaped through hole 2311 through a second connecting column below.

[0050] Two third driving mechanisms 233 are provided at the bottom of the base. A driving plate is provided at the driving end of each third driving mechanism 233. The support table 22 of each cutting device 2 is fixed on the mounting seat. A groove is provided on the side of the mounting seat. Two second connecting plates 234 are provided above and below the groove. The second connecting plates 234 and the groove of the mounting seat form two sliding channels. The protruding portions on the upper and lower sides of the second slider 231 are clamped in the sliding channels, so that the second slider 231 can slide between the two second connecting plates 234.

[0051] The mounting seat and the second connecting plate 234 below are fixed on the rectangular mounting plate, the mounting plate is set on two third sliders 235, and the base is provided with two guide rails 236 set perpendicular to the conveying direction of the first conveying platform 34. The two third sliders 235 are clamped on the guide rails 236, and the third slider 235 is connected to the driving plate.

[0052] like Figure 7 As shown, the intermediate conveyor platform 35 is located at the middle position of the rear end of the first conveyor platform 34, and the second conveyor platform 36 is located at the rear end of the intermediate conveyor platform 35. The width of the intermediate conveyor platform 35 is smaller than the widths of the first conveyor platform 34 and the third conveyor platform. On the horizontal plane, the intermediate conveyor platform 35 and the first conveyor platform 34 and the second conveyor platform 36 on either side form a clearance area to accommodate the cutting device 2.

[0053] During operation, the sections of the clips 5 to be cut are located on the transition conveyor table 35, and the cutting devices 2 on both sides of the positioning device 1 operate simultaneously. The third driving mechanism 233 drives the third slider 235 to move toward the positioning device 1, and the third slider 235 drives the support platform 22 and the cutting piece 21 to move to the bottom of the clips 5 on both sides of the material belt 6, so that the positioning knife 111 is located directly above the junction of the clips 5 and the material belt 6, and the cutting piece 21 and the positioning knife 111 are staggered and connected in the horizontal direction, and the cutting piece 21 is located directly below the elastic positioning piece 112. The first driving mechanism 13 drives the first connecting plate 14 to move downward, driving the positioning assembly to move downward, so that the abutment 113 abuts against the top of the material belt 6, and the positioning knife 111 and the elastic positioning member 112 abut against the top of the clamp 5; then the second driving mechanism 232 drives the second slider 231 to slide toward the direction close to the second connecting plate 234, and the second connecting column slides to the height of the second special-shaped through hole 2311 to make the cutting piece 21 move upward, and under the opposite forces of the cutting piece 21 and the blade of the lower end of the positioning knife 111, the clamp 5 is cut off from the material belt 6, and the cut clamp 5 falls onto the accommodating part of the support platform 22.

[0054] When the cutting piece 21 moves upward to cut the clamp 5, the abutment piece 113 abuts against the top of the connecting belt 6 to prevent the connecting belt 6 from moving during the cutting process and affecting the cutting effect; the elastic positioning piece 112 abuts against the top of the clamp 5 to prevent the clamp 5 from shaking, thereby ensuring the accuracy of the cutting position.

[0055] The cut clip 5 is placed on the support platform 22, and the third driving mechanism 233 drives the support platform 22 to move away from the positioning device 1. After the support platform 22 is reset, the six-axis robot drives the clamp to clamp the clip 5 and assemble the clip 5 in order to different positions of the conductive sheet, finally realizing the automatic cutting and installation of the clip 5, with high work efficiency, saving labor costs, and low assembly defect rate of the clip 5.

[0056] Preferably, a tape cutting mechanism 4 is provided at the tail of the second conveying table 36. The tape cutting mechanism 4 includes a sixth driving mechanism and a cutter. The cutter is arranged at the driving end of the sixth driving mechanism. Since the connecting tape 6 is continuously arranged, as the rear feeding device 3 continuously transports the connecting tape 6 behind the first conveying table 34 to the transition conveying table 35, the connecting tape 6 after removing the clip 5 is pushed by the rear connecting tape 6 as waste to the end of the second conveying table 36. The waste moves out of the second conveying table 36, and the sixth driving mechanism drives the cutter to move downward to cut the waste from the junction of the adjacent connecting tapes 6. The cut waste falls into the lower slide plate and slides into the waste box through the slide plate.

[0057] As the first alternative embodiment of Embodiment 1, the tape cutting mechanism 4 may not be provided, and the waste after removing the clip 5 is processed manually or by other means, as long as the automatic cutting system can automatically cut the clip 5.

[0058] As a further variation, the second conveying table 36 and the transition conveying table 35 may not be provided. As long as the connecting tape 6 has sufficient strength to support the clips 5 on both sides of the area to be cut during the cutting process, the cutting can be completed.

[0059] As the second alternative embodiment of Embodiment 1, the feeding device 3 may also use a belt conveyor to transport the connecting tape 6 and the clip 5 to the lower part of the positioning device 1.

[0060] As the third alternative embodiment of Embodiment 1, only one set of positioning components and the cutting device 2 may be provided. The cutting device 2 is arranged on either the left or right side of the positioning device 1, and the positioning components are arranged on either side of the first connecting plate 14 and on the same side as the cutting device 2. The same-side arrangement of the positioning components and the cutting device 2 can cooperate to complete the automatic cutting of the clip 5 on one side of the connecting tape 6.

[0061] As the fourth alternative embodiment of Embodiment 1, the third driving mechanism 233 may not be provided, and the support table 22 and the cutting member 21 are directly arranged directly below the positioning device 1, and the second driving mechanism 232 drives the cutting member 21 to move upward to complete the cutting.

[0062] As the fifth alternative embodiment of Embodiment 1, the second driving mechanism 232 may not be provided. The support table 22 and the cutting member 21 are directly arranged directly below the positioning device 1. During operation, the cutting member 21 and the support table 22 are abutted directly below the clip 5, the positioning knife 111 and the elastic positioning member 112 are abutted directly above the clip 5, and the first driving mechanism 13 drives the first connecting plate 14 to move downward, driving the positioning knife 111 to move downward to cut the clip 5.

[0063] As a sixth alternative embodiment of Embodiment 1, the first driving mechanism 13 can be vertically arranged on the frame, and the first connecting plate 14 is directly connected to the driving end of the first driving mechanism 13. The first driving mechanism 13 drives the first connecting plate 14 to move up and down.

[0064] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the embodiments. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the embodiments here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
