Cutting and seaming mechanism and winding equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 23, 2023, with application number 202311572814.8 and application name “Cutting and Seam Entry Mechanism and Winding Equipment”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of battery processing equipment, and in particular to a cutting and seaming mechanism and a winding device. Background Art

[0003] Winding equipment is a device used to process battery cores. It typically includes a winding needle with a slit. When processing a core using the winding equipment, the needle must first be inserted (the positive and negative electrodes and separators are inserted into the slit of the needle), and then the core is wound.

[0004] In the related art, in order to complete the needle insertion action, the winding needle must first be retracted in the needle seat before the needle insertion action. During the needle insertion action, the winding needle must be extended from the needle seat along its axial direction so that the positive and negative electrode sheets and the separator can just pass through the opening and enter the gap of the winding needle. Only then can the winding core be wound. However, this needle insertion method has many auxiliary actions (such as the winding needle retracting in the needle seat and extending from the needle seat), which makes the winding equipment less efficient in processing the core.

[0005] Summary of the Invention

[0006] The purpose of this application is to provide a new technical solution for a cutting and seaming mechanism and a winding device.

[0007] The present application discloses a seam-breaking mechanism and a winding device, which can improve the efficiency of the winding device in processing a winding core.

[0008] In order to achieve the above objectives, in a first aspect, the present application discloses a cutting and seam-entering mechanism, comprising:

[0009] A driving mechanism, the driving mechanism comprising a driving assembly and a moving member, the moving member being disposed on the driving assembly, and the driving assembly being configured to drive the moving member to move in a first direction toward the winding needle;

[0010] A first pressing assembly, a pushing assembly and a cutting assembly, wherein the first pressing assembly, the pushing assembly and the cutting assembly are all arranged on the moving part;

[0011] When the movable part moves along the first direction toward the winding needle, it drives the first pressing component to press the material strip against the outer wall of the winding needle, drives the cutting component to cut the material strip to form a free end, and drives the pushing component to push the free end into the gap of the winding needle.

[0012] Since the first material pressing assembly, the material pushing assembly and the material cutting assembly are all arranged on the movable part, when the driving assembly drives the movable part to move along the first direction toward the winding needle, it can drive the first material pressing assembly, the material pushing assembly and the material cutting assembly to move synchronously along the first direction toward the winding needle. In the process of the movable part driving the first material pressing assembly, the material pushing assembly and the material cutting assembly to move synchronously along the first direction toward the winding needle, the first material pressing assembly can press the material strip against the outer peripheral wall of the winding needle to fix the material strip, the cutting assembly can cut the fixed material strip to form a free end, the pushing assembly can push the free end into the gap of the winding needle, and after the free end is pushed into the gap of the winding needle, the winding needle can clamp the free end in the gap, thereby realizing the pin insertion action. Compared with the related art, before the needle insertion action is performed, it is necessary to first ensure that the winding needle is retracted in the winding needle seat, and when the needle insertion action is performed, the winding needle needs to be extended from the winding needle seat along the axial direction of the winding needle to complete the needle insertion action. This needle insertion method does not require auxiliary actions such as the winding needle retracting in the winding needle seat and extending from the winding needle seat. Therefore, when the cutting and slitting mechanism is applied to the winding equipment, the efficiency of the winding equipment in processing the core can be improved to a certain extent, making the efficiency of the winding equipment in processing the core higher.

[0013] In addition, since the first pressing component, the pushing component and the cutting component are all arranged on the movable part, and since the driving component drives the movable part to move along the first direction toward the winding needle, it can drive the first pressing component to press the material strip against the outer peripheral wall of the winding needle, drive the cutting component to cut the material strip to form a free end, and drive the pushing component to push the free end into the gap of the winding needle. That is, in the process of driving the first pressing component, the pushing component and the cutting component to move along the first direction toward the winding needle by the same driving component, the first pressing component can realize the function of pressing the material strip against the outer peripheral wall of the winding needle, the cutting component can realize the function of cutting the material strip to form a free end, and the pushing component can realize the function of pushing the free end into the gap of the winding needle. There is no need to set up separate driving mechanisms for the first pressing component, the pushing component and the cutting component respectively. Therefore, on the one hand, the structure of the cutting and slitting mechanism can be simplified and the cost of the cutting and slitting mechanism can be reduced. On the other hand, the efficiency of the needle insertion can be further improved.

[0014] Optionally, the first pressing component includes:

[0015] A pressure roller is rotatably disposed on the movable member. When the movable member moves along the first direction toward the winding needle, the pressure roller is driven to press the material strip against the outer peripheral wall of the winding needle.

[0016] Since the movable part moves along the first direction toward the winding needle, the pressure roller can press the material strip against the outer peripheral wall of the winding needle. Therefore, on the first hand, the pressure roller can play a guiding role, so that the material strip can be transmitted along the outer peripheral wall of the winding needle. On the second hand, since the outer peripheral surface of the pressure roller is relatively round, the pressure roller can avoid damaging the material strip.

[0017] Optionally, the pressing roller is a one-way rotating roller, and the rotation tangent direction of the one-way rotating roller and the winding needle at the point of contact is toward the downstream of the one-way rotating roller.

[0018] Since the rotation tangent direction of the one-way rotating roller and the winding needle is toward the downstream of the one-way rotating roller, when the one-way rotating roller is subjected to tension from the upstream of the pressure roller, the one-way rotating roller cannot rotate, so that the free end of the material strip is tightly fixed to the outer peripheral wall of the winding needle, thereby preventing the material strip from sliding toward the upstream of the pressure roller through the pressure roller when subjected to tension from the upstream of the pressure roller, so that the free end of the material strip can be fixed more firmly.

[0019] Optionally, the pressure roller is elastically connected to the movable member so as to be reciprocatingly movable along the first direction, so that when the pressure roller presses the material strip against the outer peripheral wall of the winding needle, the cutting assembly can follow the movable member and continue to move along the first direction toward the winding needle to cut the material strip to form the free end.

[0020] By making the pressure roller elastically connected to the movable member so as to be reciprocatingly movable along the first direction, the pressure roller can have a buffering function. Therefore, when the pressure roller is pressed against the outer peripheral wall of the winding needle, there will be no direct rigid contact between the pressure roller and the outer peripheral wall of the winding needle. Therefore, it can be avoided that one or both of the pressure roller and the winding needle are damaged.

[0021] Optionally, the first pressing component further includes:

[0022] a first pressing guide rod, the first pressing guide rod being slidably inserted into the moving member along the first direction;

[0023] a press support, the press support being arranged on the first press guide rod and being located on a side of the movable member close to the winding needle along the first direction, the press roller being rotatably arranged on the press support;

[0024] a first pressing stopper, which is provided on the first pressing guide rod and is limited to a side of the movable member opposite to the pressing support;

[0025] The first pressing elastic member is sandwiched between the pressing support and the moving member so that the first pressing elastic member has an elastic force that drives the pressing support and the moving member to move in opposite directions along the first direction.

[0026] By cooperating with the first pressing guide rod, the first pressing elastic member and the first pressing limit member, the purpose of elastically connecting the pressing roller to the movable member so as to be reciprocating along the first direction can be achieved. The implementation method is simple, and therefore the cost of the cutting and seam-entering mechanism can be reduced.

[0027] Optionally, the cutting component includes:

[0028] The cutter is arranged on the movable member. When the movable member moves along the first direction toward the winding needle, the cutter is driven to press against the material strip to cut the material strip to form a free end.

[0029] When the movable part moves along the first direction toward the winding needle, it will drive the cutter to directly press against the material strip, so that the material strip is cut by the cutter in a direct physical contact manner to form a free end. This method of cutting the material strip is very simple and the structural cost is low. Therefore, it can reduce the cost of the cutting and seaming mechanism while ensuring operational reliability.

[0030] Optionally, the cutting component further includes:

[0031] a cutting guide rod, the cutting guide rod being slidably inserted into the movable member along the first direction, the cutter being provided on the cutting guide rod and being located on a side of the movable member close to the winding needle along the first direction;

[0032] a cutting limiter, the cutting limiter being arranged on the cutting guide rod and being limited to a side of the moving member opposite to the cutter;

[0033] A cutting elastic member is sandwiched between the cutter and the movable member so that the cutting elastic member has an elastic force for driving the cutter to move away from the movable member along the first direction.

[0034] Optionally, the cutting component further includes:

[0035] The abutment is arranged on the cutting guide rod and is located on the side of the cutting limiter opposite to the cutter along the first direction. The first pressing assembly includes a first pressing limiter. The first pressing limiter is located on the side of the abutment facing the cutting limiter and on the moving trajectory of the abutment. When the cutter cuts off the material strip or after cutting off the material strip, the abutment abuts against the first pressing limiter.

[0036] When the pressure roller is pressed against the outer peripheral wall of the winding needle, the first material pressing limiter will stop following the moving member to continue moving along the first direction toward the winding needle. At this time, the cutter can follow the moving member to move along the first direction toward the winding needle. In the process of the cutter following the moving member to move along the first direction toward the winding needle, the abutting member will follow the cutter to move along the first direction toward the first material pressing limiter. When the cutter follows the moving member to move until it just presses against the material strip, the material strip will just be able to be cut by the cutter. At the same time, since the abutting member can just When the cutting tool is in the first position, the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, so the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, so the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the first direction, and the cutting tool will not move in the

[0037] Optionally, the position of the first pressing limiter is adjustable along the first direction.

[0038] Optionally, the pusher assembly includes:

[0039] A push plate is provided on the moving part and has a plurality of notches arranged at intervals along the axial direction of the winding needle.

[0040] By providing a notch on the push plate, when the push plate pushes the free end of the material strip into the gap of the winding needle, interference with the clamping structure in the winding needle for clamping the free end in the gap can be avoided.

[0041] Optionally, the cutting and seaming mechanism further comprises:

[0042] The second pressing assembly is arranged on the movable part and is located on the side of the cutting assembly opposite to the first pressing assembly. When the movable part moves along the first direction toward the winding needle, it drives the second pressing assembly to press the material strip against the outer peripheral wall of the winding needle or drives the second pressing assembly to press against the material strip and separate from the outer peripheral wall of the winding needle.

[0043] Since the second pressing assembly is arranged on the movable part and is located on the side of the cutting assembly opposite to the first pressing assembly, that is, the second pressing assembly is located on both sides of the cutting assembly. In this way, the second pressing assembly and the first pressing assembly can respectively fix the material strip on both sides of the cutting assembly, so that the cutting assembly can better cut the material strip.

[0044] Optionally, the cutting and seaming mechanism further comprises:

[0045] A material guiding assembly is provided on the movable member and is located on the side of the cutting assembly opposite to the first pressing assembly, and is used to guide the material strip located downstream of the cutting assembly after being cut.

[0046] Since the material guiding assembly is arranged on the movable part and is located on the side of the cutting assembly opposite to the first pressing assembly, the material guiding assembly can guide the material strip located downstream of the cutting assembly after cutting, thereby facilitating the winding of the material strip located downstream of the cutting assembly after cutting.

[0047] Optionally, the material guiding component includes:

[0048] An adsorption member is provided on the movable member, and is used for adsorbing the material strip located downstream of the cutting component after cutting to guide the material strip, wherein the adsorption force of the adsorption member on the material strip is smaller than the transmission force of the material strip to the downstream.

[0049] Since the adsorption member can adsorb the material strip located downstream of the cutting component after being cut, the adsorption member can fix the material strip, thereby preventing the material strip located downstream of the cutting component from shaking around after being cut.

[0050] Among them, since the adsorption member fixes the material strip by adsorbing the material strip to itself through adsorption force, compared with the method of fixing by clamping, the situation of damaging the material strip can be avoided.

[0051] Optionally, the first pressing assembly, the pushing assembly and the cutting assembly are arranged in sequence along the circumference of the winding needle.

[0052] In a second aspect, the present application discloses a winding device, comprising:

[0053] a winding needle having a slit;

[0054] In any one of the cutting and slitting mechanisms of the first aspect above, when the movable part moves along the first direction toward the winding needle, it drives the first pressing component to press the material strip against the outer peripheral wall of the winding needle, drives the cutting component to cut the material strip to form a free end, and drives the pushing component to push the free end into the gap of the winding needle, and the winding needle is used to clamp the free end in the gap.

[0055] Compared with the prior art, the present invention has the following advantages:

[0056] In the present application, since the first pressing assembly, the pushing assembly and the cutting assembly are all arranged on the movable part, when the driving assembly drives the movable part to move along the first direction toward the winding needle, it can drive the first pressing assembly, the pushing assembly and the cutting assembly to move synchronously along the first direction toward the winding needle. In the process of the movable part driving the first pressing assembly, the pushing assembly and the cutting assembly to move synchronously along the first direction toward the winding needle, the first pressing assembly can press the material strip against the outer peripheral wall of the winding needle to fix the material strip, the cutting assembly can cut the fixed material strip to form a free end, the pushing assembly can push the free end into the gap of the winding needle, and after the free end is pushed into the gap of the winding needle, the winding needle can clamp the free end in the gap, thereby realizing the pin insertion action. Compared with the related art, before the needle insertion action is performed, it is necessary to first ensure that the winding needle is retracted in the winding needle seat, and when the needle insertion action is performed, the winding needle needs to be extended from the winding needle seat along the axial direction of the winding needle to complete the needle insertion action. This needle insertion method does not require auxiliary actions (actions such as the winding needle retracting in the winding needle seat and extending from the winding needle seat). Therefore, when the cutting and slitting mechanism is applied to the winding equipment, the efficiency of the winding equipment in processing the core can be improved to a certain extent, making the efficiency of the winding equipment in processing the core higher.

[0057] In addition, since the first pressing component, the pushing component and the cutting component are all arranged on the movable part, and since the driving component drives the movable part to move along the first direction toward the winding needle, it can drive the first pressing component to press the material strip against the outer peripheral wall of the winding needle, drive the cutting component to cut the material strip to form a free end, and drive the pushing component to push the free end into the gap of the winding needle. That is, in the process of driving the first pressing component, the pushing component and the cutting component to move along the first direction toward the winding needle by the same driving component, the first pressing component can realize the function of pressing the material strip against the outer peripheral wall of the winding needle, the cutting component can realize the function of cutting the material strip to form a free end, and the pushing component can realize the function of pushing the free end into the gap of the winding needle. There is no need to set up separate driving mechanisms for the first pressing component, the pushing component and the cutting component respectively. Therefore, on the one hand, the structure of the cutting and slitting mechanism can be simplified and the cost of the cutting and slitting mechanism can be reduced. On the other hand, the efficiency of the needle insertion can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0081] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0082] Referring to Figures 1, 2 and 3, the cutting and slitting mechanism 200 includes: a driving mechanism 1, a first pressing component 2, a pushing component 3 and a cutting component 4, wherein the driving mechanism 1 includes a driving component 11 and a moving part 12, the moving part 12 is arranged on the driving component 11, and the driving component 11 is used to drive the moving part 12 to move along the first direction F1 toward the direction close to the winding needle 100 (the positive direction of the X-axis in Figure 3), the first pressing component 2, the pushing component 3 and the cutting component 4 are all arranged on the moving part 12, when the moving part 12 moves along the first direction F1 toward the direction close to the winding needle 100, it drives the first pressing component 2 to press the material strip A against the outer wall of the winding needle 100, drives the cutting component 4 to cut the material strip A to form a free end A1, and drives the pushing component 3 to push the free end A1 into the gap 101 of the winding needle 100.

[0083] In this embodiment, since the first pressing component 2, the pushing component 3 and the cutting component 4 are all arranged on the movable part 12, when the driving component 11 drives the movable part 12 to move along the first direction F1 toward the direction close to the winding needle 100, it can drive the first pressing component 2, the pushing component 3 and the cutting component 4 to move synchronously along the first direction F1 toward the direction close to the winding needle 100. In the process of the movable part 12 driving the first pressing component 2, the pushing component 3 and the cutting component 4 to move synchronously along the first direction F1 toward the direction close to the winding needle 100, the first pressing component 2 can press the material strip A against the outer peripheral wall of the winding needle 100, thereby fixing the material strip A, the cutting component 4 can cut the fixed material strip A to form a free end A1, the pushing component 3 can push the free end A1 into the gap 101 of the winding needle 100, and after the free end A1 is pushed into the gap 101 of the winding needle 100, the winding needle 100 can clamp the free end A1 in the gap 101, thereby realizing the pin insertion action.

[0084] Based on this, when the cutting and slitting mechanism 200 is applied to the winding device 300 for processing the battery core, the above-mentioned material strip can be understood as the positive and negative electrode sheets and diaphragms of the core. Obviously, in the process of the driving component 11 driving the moving part 12 to move along the first direction F1 toward the direction of the winding needle 100, the positive and negative electrode sheets and diaphragms can be pressed against the outer peripheral wall of the winding needle 100 by the first pressing component 2, the fixed positive and negative electrode sheets and diaphragms can be cut off to form a free end A1 by the cutting component 4, and the free end A1 can be pushed into the gap 101 of the winding needle 100 by the pushing component 3, and then the winding needle 100 is passed through. 00 Clamping the free end A1 in the gap 101 can realize the action of inserting the winding core needle. Compared with the related art, before the needle insertion action is performed, it is necessary to first ensure that the winding needle is retracted in the winding needle seat, and when the needle insertion action is performed, the winding needle needs to be extended from the winding needle seat along the axial direction of the winding needle to complete the needle insertion action. This needle insertion method does not require auxiliary actions (actions such as the winding needle retracting in the winding needle seat and extending from the winding needle seat). Therefore, when the cutting and slit mechanism 200 is used in the winding equipment, the efficiency of the winding equipment in processing the winding core can be improved to a certain extent, so that the efficiency of the winding equipment in processing the winding core is higher.

[0085] Among them, since the first pressing component 2, the pushing component 3 and the cutting component 4 are all arranged on the movable part 12, and since the driving component 11 drives the movable part 12 to move along the first direction F1 toward the direction close to the winding needle 100, it can drive the first pressing component 2 to press the material strip A against the outer peripheral wall of the winding needle 100, drive the cutting component 4 to cut the material strip A to form a free end A1, and drive the pushing component 3 to push the free end A1 into the gap 101 of the winding needle 100. That is, the first pressing component 2, the pushing component 3 and the cutting component 4 are driven by the same driving component 11 along the first direction F1 toward the winding needle During the movement in the direction of 100, the first pressing component 2 can realize the function of pressing the material strip A against the outer peripheral wall of the winding needle 100, the cutting component 4 can realize the function of cutting the material strip A to form a free end A1, and the pushing component 3 can realize the function of pushing the free end A1 into the gap 101 of the winding needle 100. There is no need to set up separate driving mechanisms for the first pressing component 2, the pushing component 3 and the cutting component 4 respectively. Therefore, on the one hand, the structure of the cutting and slitting mechanism 200 can be simplified and the cost of the cutting and slitting mechanism 200 can be reduced. On the other hand, the efficiency of the needle insertion can be further improved.

[0086] In addition, referring to Figure 3, when the cutting and seaming mechanism 200 is applied in the winding device 300, assuming that the winding device 300 includes a winding station W1 and a blanking station W2, in the related art, based on the limitations of the winding process, it is necessary to cut the material strip A at the middle position between the winding station W1 and the blanking station W2. Such a setting will make a section of the material strip A between the winding station W1 and the free end A1 longer, and this longer section of the material strip A will be wasted.

[0087] In the present application, considering that the function of the free end A1 is only to be pushed into the gap 101 of the winding needle 100 by the pushing component 3 for clamping by the winding needle 100, it does not need to be too long. Therefore, the cutting component 4 of the cutting and slitting mechanism 200 can be set close to the winding station W1, so that after the material strip A is cut, the section of the material strip A between the free end A1 and the winding station W1 is shorter, thereby saving the material strip A and avoiding waste of the material strip A.

[0088] When the movable part 12 moves along the first direction F1 toward the winding needle 100, it drives the first pressing component 2 to press the material strip A against the outer peripheral wall of the winding needle 100, drives the cutting component 4 to cut the material strip A to form a free end A1, and drives the pushing component 3 to push the free end A1 into the gap 101 of the winding needle 100. The three actions can be realized roughly simultaneously, or can be realized sequentially in chronological order. The above three actions can be realized roughly simultaneously. Specifically, it can be understood that while the first pressing component 2 presses the material strip A against the outer peripheral wall of the winding needle 100, the cutting component 4 can just cut the material strip A to form a free end A1 and the pushing component 3 can just push the free end A1 into the gap 101 of the winding needle 100. When the three actions are realized simultaneously, the needle insertion efficiency of the cutting and slitting mechanism 200 can be further improved.

[0089] When the above three actions are implemented in sequence according to the time sequence, specifically, referring to FIG4 , when the moving member 12 drives the first pressing component 2, the cutting component 4 and the pushing component 3 to move along the first direction F1 toward the direction close to the winding needle 100, first, the first pressing component 2 can press the material strip A against the outer peripheral wall of the winding needle 100, and as the moving member 12 continues to move along the first direction F1 toward the direction close to the winding needle 100, the cutting component 4 will cut the material strip A and form a free end A1 (the state in step ① in FIG4 ). After the material strip A is cut, as the moving member 12 continues to move along the first direction F1 toward the direction close to the winding needle 100, 00, the pushing component 3 will push the free end A1 into the gap 101 of the winding needle 100 (the state in step ② in Figure 4). After the free end A1 is pushed into the gap 101, the free end A1 can be clamped in the gap 101 by the winding needle 100 (the state in step ③ in Figure 4). Finally, the first pressing component 2, the pushing component 3 and the cutting component 4 can be driven by the movable part 12 to move along the first direction F1 in the direction away from the winding needle 100, so that the first pressing component 2, the pushing component 3 and the cutting component 4 are away from the winding needle 100 along the first direction F1 (the state in step ④ in Figure 4).

[0090] Of course, the above three actions may also be performed in other possible orders, as long as the purpose of cutting the material strip A and pushing the free end A1 of the material strip A into the gap 101 can be achieved. This embodiment does not limit this.

[0091] In some embodiments, referring to FIG2 , the driving assembly 11 includes a driving member 111 and a screw mechanism 112. The rotating shaft of the driving member 111 is connected to the screw of the screw mechanism 112. The moving member 12 is arranged on the moving block of the screw mechanism 112. In this way, when the driving member 111 drives the screw to rotate, it can drive the moving block to move along the first direction F1, thereby achieving the purpose of driving the moving member 12 to move along the first direction F1.

[0092] Since the screw mechanism 112 is technologically mature and has high operating precision, the moving member 12 can move more reliably and with higher motion precision when moving along the first direction F1.

[0093] The driving component 111 may be a motor or any other possible component. This embodiment does not limit the driving component 111.

[0094] In some embodiments, referring to Figures 2, 3 and 5, the first pressing assembly 2 includes: a pressing roller 21, which is rotatably disposed on the movable part 12. When the movable part 12 moves along the first direction F1 toward the direction close to the winding needle 100, it drives the pressing roller 21 to press the material strip A against the outer wall of the winding needle 100.

[0095] Since the movable part 12 moves along the first direction F1 toward the direction close to the winding needle 100, the pressure roller 21 can press the material strip A against the outer peripheral wall of the winding needle 100. Therefore, on the first hand, the pressure roller 21 can play a guiding role, so that the material strip A can be transmitted along the outer peripheral wall of the winding needle 100. On the second hand, since the outer peripheral surface of the pressure roller 21 is relatively round, the pressure roller 21 can avoid damaging the material strip A.

[0096] It can be understood that, referring to FIG. 3 , when the pressure roller 21 presses against the outer peripheral wall of the winding needle 100 , the rotation axis of the pressure roller 21 is parallel to the rotation axis of the winding needle 100 .

[0097] After the pressure roller 21 is pressed against the outer peripheral wall of the winding needle 100 and the cutting component 4 cuts the material strip A, in order to prevent the free end A1 of the material strip A from sliding toward the upstream of the pressure roller 21 (the upper side of the pressure roller 21 in Figure 6) due to the tension from the upstream of the pressure roller 21, resulting in the pressure roller 21 being unable to keep the material strip A on the outer peripheral wall of the winding needle 100, in some embodiments, see Figure 6, the pressure roller 21 is a one-way rotating roller, and the rotation tangent direction F2 of the one-way rotating roller and the winding needle 100 at the point where the one-way rotating roller is pressed is toward the downstream of the one-way rotating roller.

[0098] Since the rotation tangent direction F2 of the one-way rotating roller and the winding needle 100 is toward the downstream of the one-way rotating roller, when the one-way rotating roller is subjected to tension from the upstream of the pressure roller 21, the one-way rotating roller cannot rotate, so that the free end A1 of the material strip A is tightly fixed to the outer peripheral wall of the winding needle 100, thereby preventing the material strip A from sliding toward the upstream of the pressure roller 21 through the pressure roller 21 when subjected to tension from the upstream of the pressure roller 21, so that the free end A1 of the material strip A can be fixed more firmly.

[0099] The upstream of the pressure roller 21 refers to the side of the pressure roller 21 close to the unwinding mechanism when the cutting and slitting mechanism 200 is applied in the winding device 300 and the winding device includes an unwinding mechanism for conveying the material strip A to the winding needle 100 .

[0100] In order to avoid rigid contact between the pressure roller 21 and the winding needle 100 when the pressure roller 21 is pressed against the outer wall of the winding needle 100, which may cause one or both of the pressure roller 21 and the winding needle 100 to be damaged, and also to enable the cutting component 4 to continue to move along the first direction F1 toward the winding needle 100 following the moving part 12 when the pressure roller 21 is pressed against the outer wall of the winding needle 100, in some embodiments, referring to Figures 3 and 5, the pressure roller 21 is elastically connected to the moving part 12 for reciprocating movement along the first direction F1, so that when the pressure roller 21 presses the material strip A against the outer wall of the winding needle 100, the cutting component 4 can continue to move along the first direction F1 toward the winding needle 100 following the moving part 12 to cut the material strip A to form a free end A1.

[0101] By elastically connecting the pressure roller 21 to the movable member 12 so as to be reciprocatable along the first direction F1, the pressure roller 21 can be given a buffering function. Therefore, when the pressure roller 21 presses against the outer peripheral wall of the winding needle 100, on the one hand, there will be no direct rigid contact between the pressure roller 21 and the outer peripheral wall of the winding needle 100, thereby preventing damage to one or both of the pressure roller 21 and the winding needle 100. On the other hand, when the pressure roller 21 presses against the outer peripheral wall of the winding needle 100, the cutting assembly 4 can continue to move along the first direction F1 toward the winding needle 100 with the movable member 12, so that the cutting assembly 4 can cut the material strip A to form a free end A1.

[0102] There are many ways in which the pressing roller 21 can be elastically connected to the movable member 12 for reciprocating motion along the first direction F1. In one possible implementation, referring to Figures 3 and 5, the first pressing assembly 2 also includes: a first pressing guide rod 22, a pressing support 23, a first pressing limiter 24 and a first pressing elastic member 25, wherein the first pressing guide rod 22 is slidably inserted in the movable member 12 along the first direction F1 (the X-axis direction in Figure 5), the pressing support 23 is provided on the first pressing guide rod 22 and is located at the position where the movable member 12 moves along the first direction F1. On the side of the winding needle 100 in a direction F1 (the right side of the movable part 12 in Figure 5), the pressure roller 21 is rotatably arranged on the pressure support 23, the first pressure limiter 24 is arranged on the first pressure guide rod 22 and is limited to the side of the movable part 12 opposite to the pressure support 23 (the left side of the movable part 12 in Figure 5), and the first pressure elastic part 25 is clamped between the pressure support 23 and the movable part 12, so that the first pressure elastic part 25 has an elastic force to drive the pressure support 23 to move along the first direction F1 away from the movable part 12.

[0103] In this embodiment, since the first pressing guide rod 22 is slidably inserted into the movable member 12 along the first direction F1, the pressing support 23 is arranged on the first pressing guide rod 22 and is located on the side of the movable member 12 along the first direction F1 close to the winding needle 100, and the first pressing limiter 24 is arranged on the first pressing guide rod 22 and is limited to the side of the movable member 12 opposite to the pressing support 23, therefore, the movable member 12 will be limited between the first pressing limiter 24 and the pressing support 23, that is, the movable member 12 can slide between the pressing support 23 and the first pressing limiter 24 along the first direction F1, and since the first pressing elastic member 25 is clamped between the pressing support 23 and the movable member 12, the first pressing elastic member 25 can drive the pressing support 23 to move along the first direction F1 toward away from the movable member 12 until the movable member 12 is in a state of abutting against the first pressing limiter 24.

[0104] In this state, when the movable member 12 moves along the first direction F1 toward the direction close to the winding needle 100, driving the pressure roller 21 to press against the outer wall of the winding needle 100, as the movable member 12 continues to move along the first direction F1 toward the direction close to the winding needle 100, the pressure roller 21 will not be able to continue moving with the movable member 12 due to the blocking effect of the winding needle 100. At this time, the movable member 12 will leave the first material pressing limit member 24 and move along the first material pressing guide rod 22 toward the direction close to the pressure roller 21, and the first material pressing elastic member 25 will continue to be compressed and the degree of compression will increase.

[0105] When the movable member 12 moves in the first direction F1 away from the winding needle 100 (the negative direction of the X-axis in FIG. 3 ), driving the pressure roller 21 away from the outer peripheral wall of the winding needle 100, as the movable member 12 moves in the first direction F1 away from the winding needle 100, the first press elastic member 25 drives the press support 23 to move along the first press guide rod 22 away from the movable member 12, and the first press elastic member 25 is restored, and the movable member 12 is again in a state of abutting against the first press stopper 24. During the process of compression and restoration of the first press elastic member 25, the distance between the movable member 12 and the pressure roller 21 can be reduced or increased, thereby achieving the purpose of elastically connecting the pressure roller 21 to the movable member 12 so that it can reciprocate in the first direction F1.

[0106] It can be seen that through the cooperation between the first pressing guide rod 22, the first pressing elastic member 25 and the first pressing limit member 24, the purpose of elastically connecting the pressing roller 21 to the movable member 12 so that it can reciprocate along the first direction F1 can be achieved. The implementation method is simple, and therefore, the cost of the cutting and seam-entering mechanism 200 can be reduced.

[0107] Of course, the pressing roller 21 may also be elastically connected to the moving member 12 in a reciprocating manner along the first direction F1 by other means, which will not be listed here in this embodiment.

[0108] It should be noted that the first pressing guide rod 22 may be a cylindrical structure or a square rod structure, etc., which is not limited in this embodiment. The first pressing stopper 24 may be a stopper ring, etc., which is not limited in this embodiment. The first pressing elastic member 25 may be a spring, a spring, or any other possible elastic element, which is not limited in this embodiment.

[0109] It should also be noted that the above-mentioned first pressing guide rod 22 can be slidably inserted into the movable part 12 along the first direction F1 through a linear bearing, or can be slidably inserted into the movable part 12 through other methods. For example, it can be achieved by opening a guide hole on the movable part 12 that passes through the movable part 12 along the first direction F1, and then slidably inserting the first pressing guide rod 22 into the guide hole along the first direction F1. This embodiment is not limited here.

[0110] Based on the above description, it can be seen that the cutting component 4 has the function of cutting the material strip A to form a free end A1, wherein there are multiple ways for the cutting component 4 to cut the material strip A. For example, in one possible implementation method, the material strip A can be cut by laser cutting. When the cutting component 4 cuts the material strip A by laser cutting, there is no need for direct contact between the cutting component 4 and the material strip A. Therefore, the structural design difficulty of the cutting component 4 can be reduced.

[0111] Of course, the material strip A can also be cut in other possible ways. For example, in another possible implementation, referring to Figures 3 and 5, the cutting component 4 includes: a cutter 41, and the cutter 41 is arranged on the movable part 12. When the movable part 12 moves along the first direction F1 toward the direction close to the winding needle 100, it drives the cutter 41 to press against the material strip A to cut the material strip A to form a free end A1.

[0112] It can be seen that in this implementation, when the movable member 12 moves along the first direction F1 toward the winding needle 100, it will drive the cutter 41 to directly press against the material strip A, so that the material strip A is cut by the cutter 41 in a direct physical contact manner to form a free end A1. This method of cutting the material strip A is very simple and has a low structural cost. Therefore, the cost of the cutting and seaming mechanism 200 can be reduced while ensuring operational reliability.

[0113] In some embodiments, referring to FIG. 5 , the position of the first pressing stopper 24 relative to the first pressing guide rod 22 along the first direction F1 is adjustable.

[0114] By making the position of the first press stopper 24 relative to the first press guide rod 22 adjustable along the first direction F1, on the one hand, the distance between the press support 23 and the first press stopper 24 can be adjusted, and then the sliding stroke of the movable member 12 between the press support 23 and the first press stopper 24 along the first direction F1 can be adjusted, thereby making the application scenarios of the cutting and seaming mechanism 200 wider. On the other hand, by adjusting the position of the first press stopper 24 relative to the first press guide rod 22 along the first direction F1, the purpose of adjusting the compression degree of the first press elastic member 25 can be achieved, which can avoid the situation where the distance between the press support 23 and the first press stopper 24 is too large, causing the first press elastic member 25 to become loose and unable to abut between the movable member 12 and the press support 23 respectively.

[0115] In order to prevent the cutter 41 from continuously moving along the first direction F1 toward the winding needle 100 after the cutter 41 cuts the material strip A, causing the cutter 41 to be inserted too deeply into the outer wall of the winding needle 100, so that a deep avoidance groove needs to be excavated on the outer wall of the winding needle 100 to avoid the cutter 41, in some embodiments, referring to Figures 3 and 5, the cutting assembly 4 further includes: a cutting guide rod 42, a cutting limiter 43 and a cutting elastic member 44, wherein the cutting guide rod 4 The cutting blade 41 is slidably inserted into the movable member 12 along the first direction F1. The cutting blade 41 is disposed on the cutting guide rod 42 and is located on the side of the movable member 12 close to the winding needle 100 along the first direction F1. The cutting blade stopper 43 is disposed on the cutting guide rod 42 and is limited to the side of the movable member 12 opposite to the cutting blade 41. The cutting blade elastic member 44 is sandwiched between the cutting blade 41 and the movable member 12 so that the cutting blade elastic member 44 has an elastic force to drive the cutting blade 41 to move away from the movable member 12 along the first direction F1.

[0116] Such a configuration allows the cutter 41 to be elastically connected to the movable member 12 for reciprocating motion along the first direction F1, that is, a buffered contact between the cutter 41 and the material strip A can be achieved. In this way, when the material strip A is relatively hard, the cutter 41 can be prevented from being damaged.

[0117] Among them, the setting position, working principle and structure of the cutting guide rod 42, the cutting limiter 43 and the cutting elastic member 44 can refer to the description of the first pressing guide rod 22, the first pressing limiter 24 and the first pressing elastic member 25 in the above text, and this embodiment will not be described in detail here.

[0118] Furthermore, in order to better avoid the situation that after the cutter 41 cuts the material strip A, the cutter 41 will continue to move along the first direction F1 toward the winding needle 100 following the moving part 12, resulting in the need to dig a deep avoidance groove on the outer wall of the winding needle 100 for avoiding the cutter 41, thereby weakening the mechanical strength of the winding needle 100, in some embodiments, see Figure 5, the cutting assembly 4 further includes: a supporting member 45, the supporting member 45 is arranged on the cutting guide rod 42 And along the first direction F1, it is located on the side of the cutting limiter 43 opposite to the cutter 41 (the left side of the cutting limiter 43 in Figure 5), the first pressing assembly 2 includes a first pressing limiter 24, the first pressing limiter 24 is located on the side of the abutment 45 facing the cutting limiter 43 (the right side of the abutment 45 in Figure 5) and is located on the moving trajectory of the abutment 45, when the cutter 41 cuts off the material strip A or after cutting off the material strip A, the abutment 45 abuts against the first pressing limiter 24.

[0119] With such arrangement, after the pressure roller 21 presses against the outer peripheral wall of the winding needle 100, the first material pressing limiter 24 will stop following the moving member 12 to continue moving along the first direction F1 toward the winding needle 100. At this time, the cutter 41 can follow the moving member 12 to move along the first direction F1 toward the winding needle 100. In the process that the cutter 41 follows the moving member 12 to move along the first direction F1 toward the winding needle 100, the abutting member 45 will follow the cutter 41 to move along the first direction F1 toward the first material pressing limiter 24. When the cutter 41 follows the moving member 12 to move until it just presses against the material strip A, the material strip A will just be able to be cut by the cutter 41. At the same time, due to the abutting member Component 45 can just move to abut against the first material pressing limit component 24, and when the abutting component 45 abuts against the first material pressing limit component 24, the first material pressing limit component 24 will prevent the abutting component 45 from continuing to move along the first direction F1 toward the winding needle 100, thereby making it impossible for the cutter 41 to continue to move along the first direction F1 toward the winding needle 100, thereby avoiding the situation where the cutter 41 continues to follow the moving component 12 to move along the first direction F1 toward the winding needle 100 after cutting off the material strip A, thereby avoiding the need to dig a very deep avoidance groove on the outer peripheral wall of the winding needle 100, which causes the mechanical strength of the winding needle 100 to be weakened.

[0120] The abutting member 45 may be a plate-shaped structure. Of course, the abutting member 45 may also be other possible structures, which is not limited in this embodiment.

[0121] It is worth noting that, based on the above description, it can be known that in the process of the abutment 45 following the cutter 41 to move along the first direction F1 toward the direction close to the first pressure limiter 24, when the abutment 45 abuts against the first pressure limiter 24, the cutter 41 will stop moving. Therefore, the position of the first pressure limiter 24 relative to the abutment 45 is related to the timing when the cutter 41 stops moving. The present application makes the position of the first pressure limiter 24 relative to the first pressure guide rod 22 adjustable along the first direction F1, so that the position of the first pressure limiter 24 relative to the abutment 45 can be adjusted, and then the timing when the cutter 41 stops moving can be adjusted, thereby better ensuring that the cutter 41 stops moving after cutting the material strip A, and thus better avoiding the need to excavate a very deep avoidance groove on the outer peripheral wall of the winding needle 100.

[0122] In order to make the abutment 45 more stable when following the cutter 41 in the first direction F1 toward the first press stopper 24, in some embodiments, as shown in FIG5 , a through hole is provided on the abutment 45, and the first press guide rod 22 passes through the through hole along the first direction F1. In this way, the first press guide rod 22 can guide the abutment 45, making the abutment 45 more stable when following the cutter 41 in the first direction F1 toward the first press stopper 24.

[0123] In some embodiments, referring to FIG. 3 and FIG. 7 , the pusher assembly 3 includes a pusher plate 31 disposed on the movable member 12 and having a plurality of notches 311 spaced apart along the axial direction of the winding needle 100 (the Y-axis direction in FIG. 7 ).

[0124] By providing a notch 311 on the push plate 31, when the push plate 31 pushes the free end A1 of the material strip A into the gap 101 of the winding needle 100, interference with the clamping structure in the winding needle for clamping the free end A1 in the gap 101 can be avoided.

[0125] Specifically, the clamping structure may also be provided with a protrusion matching the notch 311 . When the push plate 31 enters the gap 101 , the notch 311 can just be used to accommodate the protrusion, thereby avoiding interference between the push plate 31 and the clamping structure.

[0126] In some embodiments, referring to Figures 1 and 5, the cutting and seaming mechanism 200 also includes: a second pressing assembly 5, the second pressing assembly 5 is arranged on the movable part 12 and is located on the side of the cutting assembly 4 opposite to the first pressing assembly 2, when the movable part 12 moves along the first direction F1 toward the direction close to the winding needle 100, it drives the second pressing assembly 5 to press the material strip A against the outer peripheral wall of the winding needle 100 or drives the second pressing assembly 5 to press against the material strip A and separate from the outer peripheral wall of the winding needle 100.

[0127] Since the second pressing component 5 is arranged on the movable part 12 and is located on the side of the cutting component 4 opposite to the first pressing component 2, that is, the second pressing component 5 is located on both sides of the cutting component 4. In this way, the second pressing component 5 and the first pressing component 2 can fix the material strip A on both sides of the cutting component 4 respectively, so that the cutting component 4 can better cut the material strip A.

[0128] In addition, when the movable member 12 moves along the first direction F1 toward the winding needle 100, it can drive the second pressing assembly 5 to press the material strip A against the outer peripheral wall of the winding needle 100, or drive the second pressing assembly 5 to press the material strip A against the outer peripheral wall of the winding needle 100 and detach from the outer peripheral wall of the winding needle 100. With this arrangement, when the outer peripheral wall area of ​​the winding needle 100 is large, the second pressing assembly 5 can be driven to press the material strip A against the outer peripheral wall of the winding needle 100, so that the material strip A can be better fixed. When the outer peripheral wall area of ​​the winding needle 100 is small and there is no free space for the second pressing assembly 5 to press thereon, the second pressing assembly 5 can be driven to press the material strip A against the outer peripheral wall of the winding needle 100 and detach from the outer peripheral wall of the winding needle 100. With this arrangement, the material strip A can also be fixed to a certain extent without occupying the space on the outer peripheral wall of the winding needle 100, and it can be suitable for scenarios with small winding needles.

[0129] It is worth noting that the above-mentioned fixing of the material strip A does not mean that the material strip A is completely fixed on the outer peripheral wall of the winding needle 100 and does not move, but that the material strip A can be relatively flat under the action of the second pressing component 5 and the first pressing component 2, which is convenient for the cutting component 4 to perform the cutting work.

[0130] In some embodiments, referring to Figures 1 and 5, the second pressing assembly 5 includes a pressing block 53, which is elastically connected to the movable member 12 for reciprocating movement along the first direction F1, so that when the pressing block 53 presses the material strip A against the outer peripheral wall of the winding needle 100 or presses against the material strip A and detaches from the outer peripheral wall of the winding needle 100, the cutting assembly 4 can follow the movable member 12 and continue to move along the first direction F1 toward the winding needle 100 to cut the material strip A to form a free end A1.

[0131] This arrangement allows, on the one hand, the pressing block 53 to provide a buffer when pressing against the outer wall of the winding needle 100, thereby preventing rigid contact between the pressing block 53 and the winding needle 100, which could damage at least one of them. On the other hand, when the pressing block 53 presses against the outer wall of the winding needle 100, the cutting assembly 4 can continue to move in the first direction F1 toward the winding needle 100, following the moving member 12, so that the cutting assembly 4 can cut the material strip A to form a free end A1.

[0132] In other embodiments, the pressing block 53 may also be replaced by a pressing roller, which is not limited in this embodiment.

[0133] Among them, there are many ways to realize that the above-mentioned pressing block 53 can be elastically connected to the moving member 12 for reciprocating movement along the first direction F1. In one possible implementation, referring to Figures 1 and 5, the second pressing assembly 5 includes: a connecting member 51, a second pressing guide rod 52, a second pressing limiter 54 and a second pressing elastic member 55, wherein the connecting member 51 is connected to the moving member 12, the second pressing guide rod 52 is slidably inserted in the connecting member 51 along the first direction F1, and the pressing block 53 is arranged on the second pressing guide rod 52 and is located close to the connecting member 51 along the first direction F1. On the side near the winding needle 100, when the movable part 12 moves along the first direction F1 toward the winding needle 100, it drives the pressure block 53 to press the material strip A against the outer peripheral wall of the winding needle 100 or press the material strip A and separate from the outer peripheral wall of the winding needle 100. The second material pressing limiter 54 is arranged on the second material pressing guide rod 52 and is limited to the side of the connecting member 51 opposite to the pressure block 53. The second material pressing elastic member 55 is clamped between the pressure block 53 and the connecting member 51, so that the second material pressing elastic member 55 has the elastic force to drive the pressure block 53 to move along the first direction F1 toward away from the connecting member 51.

[0134] The principle that the pressure block 53 has a buffering function is similar to the principle that the pressure roller 21 has a buffering function, and will not be described in detail in this embodiment.

[0135] In addition, the structure of the second pressing guide rod 52 can be similar to that of the first pressing guide rod 22, the structure of the second pressing limiter 54 can be similar to that of the first pressing limiter 24, and the structure of the second pressing elastic member 55 can be similar to that of the first pressing elastic member 25. For details, please refer to the description of the first pressing guide rod 22, the first pressing limiter 24 and the first pressing elastic member 25 in the above embodiment, and this embodiment will not be repeated here.

[0136] In some embodiments, referring to Figures 3, 5 and 8, the cutting and slitting mechanism 200 also includes: a material guiding assembly 6, which is arranged on the movable part 12 and is located on the side of the cutting assembly 4 opposite to the first pressing assembly 2, and the material guiding assembly 6 is used to guide the material strip A located downstream of the cutting assembly 4 after cutting.

[0137] Since the material guiding assembly 6 is arranged on the movable part 12 and is located on the side of the cutting assembly 4 opposite to the first pressing assembly 2, the material guiding assembly 6 can guide the material strip A located downstream of the cutting assembly 4 after cutting, thereby facilitating the winding of the material strip A located downstream of the cutting assembly 4 after cutting.

[0138] For example, referring to Figure 3, when the cutting and slitting mechanism 200 is applied in the winding device 300, assuming that the winding device 300 includes a winding station W1 and a unloading station W2, after the cutting component 4 cuts the material strip A, the material strip A located between the unloading station W2 and the cutting component 4 will lose support and swing around, that is, the material strip A located downstream of the cutting component 4 will swing around. Based on this, the present application arranges the material guide component 6 on the movable part 12 and on the side of the cutting component 4 opposite to the first pressing component 2. The material guide component 6 can well guide the material strip A located downstream of the cutting component 4 after cutting, thereby facilitating the winding of the part of the material strip A on the reel located at the unloading station W2.

[0139] In some embodiments, referring to FIG8 , the material guiding component 6 includes: an adsorption member 61, which is arranged on the movable member 12, and the adsorption member 61 is used to adsorb the material strip A located downstream of the cutting component 4 after cutting to guide the material strip A, wherein the adsorption force of the adsorption member 61 on the material strip A is less than the transmission force of the material strip A to the downstream.

[0140] Since the adsorption part 61 can adsorb the material strip A located downstream of the cutting component 4 after cutting, the adsorption part 61 can fix the material strip A, thereby preventing the material strip A located downstream of the cutting component 4 from shaking around after cutting.

[0141] Among them, since the adsorption member 61 fixes the material strip A by adsorbing it to itself through adsorption force, compared with the method of fixing by clamping, the situation of damaging the material strip A can be avoided.

[0142] In addition, since the adsorption force of the adsorption component 61 on the material strip A is smaller than the transmission force of the material strip A to the downstream, the adsorption component 61 only plays a role of fixing and guiding, and does not completely fix the material strip A. That is, the adsorption component 61 only plays a role of pulling the material strip, thereby facilitating the material strip A to continue to be transmitted downstream to realize the winding of the material strip A.

[0143] Among them, the above-mentioned adsorption part 61 can be an adsorption plate, and vacuum suction holes can be set on the adsorption plate to adsorb the material strip A through the vacuum suction holes. Of course, the material strip A can also be adsorbed by other methods, which is not limited in this embodiment.

[0144] In order to better absorb the material strip A through the adsorption member 61 to better pull the material strip A, in some embodiments, referring to FIG8 , the material guide assembly 6 further includes: a material guide driving member 62, the material guide driving member 62 is arranged on the movable member 12, the adsorption member 61 is arranged on the material guide driving member 62, and the material guide driving member 62 is used to drive the adsorption member 61 to move along the first direction F1 until it abuts against the material strip A to absorb the material strip A.

[0145] Since the adsorption component 61 is arranged on the material guide driving component 62, the material guide driving component 62 can drive the adsorption component 61 to move along the first direction F1 until it abuts against the material strip A. Therefore, on the one hand, the vacuum suction hole of the adsorption component 61 can be better fitted to the material strip A, so that the adsorption component 61 has a better adsorption effect on the material strip A. On the other hand, by adjusting the driving stroke of the material guide driving component 62, the adsorption component 61 can also adjust the guide trajectory of the material strip A, which is convenient for the subsequent winding of the material strip A.

[0146] The material guide drive member 62 may be any possible device such as a cylinder or an electric cylinder, as long as it can drive the adsorption member 61 to move along the first direction F1 until it abuts against the material strip A. This embodiment does not limit the material guide drive member 62.

[0147] Furthermore, in some embodiments, referring to FIG8 , the material guide assembly 6 also includes: a material guide support 63 and a material guide roller 64, the material guide support 63 is slidably arranged on the movable member 12 along the first direction F1, the material guide driving member 62 is used to drive the material guide support 63 to move along the first direction F1 (X-axis direction in FIG8 ), the adsorption member 61 and the material guide roller 64 are both arranged on the material guide support 63, and the material guide roller 64 is used to abut against the material strip A to guide the material strip A when the material guide driving member 62 drives the material guide support 63 to move along the first direction F1.

[0148] Since the adsorption component 61 and the material guide roller 64 are both arranged on the material guide support 63, when the material guide driving component 62 drives the material guide support 63 to move along the first direction F1, the adsorption component 61 and the material guide roller 64 can be synchronously driven to move along the first direction F1 so that the adsorption component 61 and the material guide roller 64 can both abut against the material strip A to guide the material strip A. Under the dual guiding action of the adsorption component 61 and the material guide roller 64, the guiding effect on the material strip A can be better.

[0149] In addition, since the material guiding support 63 is slidably disposed on the moving member 12 along the first direction F1 , when the material guiding driving member 62 drives the material guiding support 63 to move along the first direction F1 , the material guiding support 63 will move more smoothly.

[0150] Among them, the material guide support 63 can be slidably set on the movable part 12 along the first direction F1 in a variety of ways. In one possible implementation method, see Figure 8, a material guide rod 65 extending along the first direction F1 is provided on the material guide support 63, and a guide hole penetrating the movable part 12 along the first direction F1 can be opened on the movable part 12. The material guide rod 65 is slidably inserted in the guide hole along the first direction F1. In this way, the purpose of slidably setting the material guide support 63 on the movable part 12 along the first direction F1 can be achieved.

[0151] The number of the material guiding rods 65 may be one, two, or three, etc. The present embodiment does not limit the number of the material guiding rods 65 .

[0152] In some embodiments, referring to FIG. 3 , the first pressing assembly 2 , the pushing assembly 3 and the cutting assembly 4 are sequentially arranged along the circumference of the winding needle 100 .

[0153] By arranging the first pressing component 2, the pushing component 3 and the cutting component 4 in sequence along the circumference of the winding needle 100, the pushing component 3 can be located between the first pressing component 2 and the cutting component 4 along the circumference of the winding needle 100. This arrangement makes it convenient for the cutting component 4 to cut the material strip A and then push the free end A1 into the gap 101 of the winding needle 100 through the pushing component 3.

[0154] The present application also provides a winding device 300, see Figure 3, the winding device 300 includes: a winding needle 100 and a cutting and slitting mechanism 200, wherein the winding needle 100 has a gap 101, and when the movable part 12 moves along the first direction F1 toward the direction close to the winding needle 100, it drives the first pressing component 2 to press the material strip A against the outer wall of the winding needle 100, drives the cutting component 4 to cut the material strip A to form a free end A1, and drives the pushing component 3 to push the free end A1 into the gap 101 of the winding needle 100, and the winding needle 100 is used to clamp the free end A1 in the gap 101.

[0155] Among them, the structure of the cutting and seaming mechanism 200 can be the same as the structure of any cutting and seaming mechanism 200 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and this embodiment will not go into details.

[0156] In this embodiment, since the cutting and slitting mechanism 200 does not need to perform auxiliary actions (such as the winding needle retracting in the winding needle seat and extending from the winding needle seat) when performing the needle insertion action, when the cutting and slitting mechanism 200 is used in the winding equipment, it can improve the efficiency of the winding equipment in processing the winding core to a certain extent, making the efficiency of the winding equipment in processing the winding core higher.

[0157] In addition, since the cutting and slitting mechanism 200 can use the same driving component 11 to enable the first pressing component 2 to press the material strip A against the outer wall of the winding needle 100, the cutting component 4 to cut the material strip A to form a free end A1, and the pushing component 3 to push the free end A1 into the gap 101 of the winding needle 100, there is no need to set up separate driving mechanisms for the first pressing component 2, the pushing component 3 and the cutting component 4 respectively. Therefore, on the one hand, the structure of the cutting and slitting mechanism 200 can be simplified and the cost of the cutting and slitting mechanism 200 can be reduced. On the other hand, the efficiency of the needle insertion can be further improved.

[0158] Based on this, when the winding device 300 includes the cutting and slitting mechanism 200, the cost of the winding device 300 can be reduced, the needle insertion efficiency of the winding device 300 can be improved, and the efficiency of the winding device in processing the winding core is higher.
