For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] like Figures 1 to 7As shown, this embodiment provides an automatic wire film wrapping mechanism 200 for wrapping a processing section of a wire product with a protective film, wherein the processing section is located between two clamping sections, and the automatic wire film wrapping mechanism 200 includes a wrapping module and a feeding module; the wrapping module includes a rotating film wrapping clamp 230 and two wire clamping units 220, wherein the two wire clamping units 220 are respectively used to selectively fix the two clamping sections, and the rotating film wrapping clamp 230 includes a fixed clamping unit and a dynamic clamping unit movably connected to the fixed clamping unit, and both the fixed clamping unit and the dynamic clamping unit are provided with The wrapping groove and the rotating film wrapping clamp 230 can switch between the wrapping state and the waiting state. When the dynamic clamping line unit is in the wrapping state, the two wrapping grooves form a wrapping through hole, and the hole wall of the wrapping through hole can fit with the processing section. When the dynamic clamping line unit is in the waiting state, the two wrapping grooves are arranged at intervals, and the rotating film wrapping clamp 230 can rotate around the axis of the wrapping through hole; the feeding module is used to place the protective film at the film feeding position on the rotating film wrapping clamp 230 in the waiting state, and the protective film located at the film feeding position is at least partially placed in the wrapping groove.

[0042] The automatic wire film wrapping mechanism 200 uses the setting of the rotating film wrapping clamp 230 and the two wire clamping units 220 to wrap the protective film sandwiched between the wall of the wrapping through hole and the wire product on the outer surface of the processing section during the rotation process, so as to realize the automatic wrapping of the wire product with the protective film. The above scheme avoids the tediousness and errors of manual operation, improves the efficiency of the film wrapping operation and the wrapping accuracy of the protective film. According to the switching of the rotating film wrapping clamp 230 between the wrapping state and the waiting state, the selective contact between the wrapping slot and the processing section is realized, which is convenient for moving the wire product and conveying the protective film, thereby realizing the fast and accurate wrapping of the wire product with the protective film, which helps to avoid the position conflict between the wrapping module and the feeding module. At the same time, the automatic wire film wrapping mechanism 200 places the processing section between the two clamping sections, and uses the wire clamping unit 220 for selective fixation to ensure the stability and accuracy of the wire product during the wrapping process. Through the above structural improvement of the automatic wire film wrapping mechanism 200, it is possible to use a cylindrical film wrapping method to wrap the surface of the wire product in a roll, thereby optimizing the material supply method, helping to reduce the material cost, facilitating the improvement of the automation level of the automatic wire film wrapping mechanism 200, reducing the operating difficulty and cost of the automatic wire film wrapping mechanism 200, reducing the workload of operators, and improving the work efficiency of the film wrapping operation.

[0043] Before the film wrapping operation, the rotating film wrapping clamp 230 is in a waiting state, so that the two wrapping slots are set at intervals. After the protective film is fed into the wrapping slot, the rotating film wrapping clamp 230 is switched to the wrapping state to achieve accurate fitting of the wire product with the wall of the wrapping through hole; when the rotating film wrapping clamp 230 rotates, the wire clamping unit 220 clamps the wire product, so that the wire product is not driven to rotate by the rotating film wrapping clamp 230, so that the protective film can be smoothly wrapped on the outer surface of the wire product; after the film wrapping operation is completed, the wire clamping unit 220 releases the wire product, so that the wrapped wire product can be sent out.

[0044] In this embodiment, the wire product can move periodically along the axis of the wrapping through hole, so that various locations on the wire product can be used as processing sections in turn for film wrapping operations, thereby achieving automatic film wrapping of the entire wire product.

[0045] In this embodiment, the wire automatic film wrapping mechanism 200 also includes a mechanism seat 280, and the wrapping module and the feeding module are both arranged on the mechanism seat 280; the wrapping module includes a rotating drive assembly 260, and the rotating drive assembly 260 drives the rotating film wrapping fixture 230 to rotate through a belt to achieve selective rotation of the rotating film wrapping fixture 230.

[0046] In this embodiment, the dynamic clamping line unit includes a guide rod 231 and a fixed pressure line block 232 fixedly connected to the guide rod 231, and a wrapping groove is arranged on the fixed pressure line block 232. The dynamic clamping line unit includes a dynamic pressure line block 233 and a pressure block 234 fixedly connected to the dynamic pressure line block 233, and the wrapping groove is arranged on the dynamic pressure line block 233. The dynamic pressure line block 233 is elastically connected to the guide rod 231 through an elastic member, and the elastic member is used to push the dynamic pressure line block 233 against the fixed pressure line block 232; the wrapping module also includes a pressing assembly 250, and the pressing assembly 250 selectively pushes the pressure block 234 to move the dynamic pressure line block 233 away from the fixed pressure line block 232.

[0047] The design of the dynamic clamping unit enables the rotating film wrapping clamp 230 to fit the processing section more closely. The cooperation between the guide rod 231 and the fixed pressure line block 232 and the dynamic pressure line block 233 ensures the accurate formation of the wrapping through hole. The elastic member pushes the dynamic pressure line block 233 against the fixed pressure line block 232, ensuring the stability and reliability of the wrapping process. At the same time, the pressing assembly 250 in the wrapping module selectively pushes the pressure block 234, so that the dynamic pressure line block 233 can be away from the fixed pressure line block 232, thereby facilitating the movement of the wire product and the feeding of the protective film, and ensuring the smooth progress of the film wrapping operation.

[0048] Before the film wrapping operation, the pressing assembly 250 presses the pressure block 234 to separate the dynamic pressure line block 233 from the fixed pressure line block 232. After the protective film is sent into the wrapping groove, the pressing assembly 250 detaches from the pressure block 234, and the dynamic pressure line block 233 elastically returns to its original position and abuts against the fixed pressure line block 232.

[0049] The pressing assembly 250 includes a pressing end 251 and a pressing driving unit 252. The pressing driving unit 252 is used to drive the pressing end 251. The pressing end 251 can press against the pressing block 234, so as to switch the rotating film wrapping clamp 230 to the waiting state. Specifically, the pressing driving unit 252 is a servo motor. The pressing assembly 250 is a conventional structure in the art. Its working principle and specific structure are common knowledge in the art and are well known to those skilled in the art, so no further description is given here.

[0050] Furthermore, the guide rod 231 is penetrated by a positioning hole 2311, the positioning hole 2311 is coaxial with the wrapping through hole, a receiving cavity is provided in the middle of the guide rod 231, the positioning hole 2311 is connected to the receiving cavity, the fixed pressure line block 232 is fixedly connected to the inner wall of the receiving cavity, the dynamic pressure line block 233 at least partially extends into the receiving cavity, and the pressure block 234 is arranged outside the guide rod 231.

[0051] The coaxial design of the positioning hole 2311 on the guide rod 231 and the wrapping through hole plays a guiding role for the wire product, realizes the accurate positioning of the wire product in the wrapping through hole, ensures the smooth completion of the film wrapping operation, and thus guarantees the stable operation of the rotating film wrapping fixture 230. The design of the accommodating cavity enables the fixed pressure wire block 232 and the dynamic pressure wire block 233 to be firmly connected, ensuring the precise formation of the wrapping groove and the wrapping through hole. In addition, the design of the guide rod 231 also facilitates the flexible operation and maintenance of the dynamic clamping unit. Moreover, the fixed pressure wire block 232 is fixedly connected to the inner wall of the accommodating cavity, and the dynamic pressure wire block 233 partially extends into the accommodating cavity. The above design makes the structure of the rotating film wrapping fixture 230 more compact, while ensuring the stability and reliability of the dynamic clamping unit.

[0052] Furthermore, two wire clamping units 220 are respectively disposed at two ends of the positioning hole 2311 , and the wire clamping units 220 are used to radially clamp the clamping section.

[0053] The design of the wire clamping unit 220 makes the clamping of the wire product more stable and reliable. Through the selective fixation of the wire clamping unit 220, the stability and accuracy of the wire product during the wrapping process are ensured. The two wire clamping units 220 are respectively arranged at both ends of the positioning hole 2311, which is convenient for cooperation with the rotating film wrapping fixture 230 and improves work efficiency. The above design makes the fixation of the wire product more stable and avoids the movement or deviation of the wire product during the film wrapping process.

[0054] The wire clamping unit 220 is a conventional structure in the art, and its purpose is to selectively clamp the clamping section of the wire product. Its working principle and specific structure are common knowledge in the art and are well known to technicians in the art, so they will not be elaborated here.

[0055] In this embodiment, the wrapping module further includes a locking unit 281 , and the locking unit 281 selectively fixes the rotating film wrapping fixture 230 .

[0056] The locking unit 281 can selectively fix the rotating film wrapping fixture 230, thereby preventing the rotating film wrapping fixture 230 from accidentally shifting its position, ensuring that the rotating film wrapping fixture 230 remains in the same position while waiting for material loading, preventing accidental movement or rotation, and improving the stability and reliability of the wire automatic film wrapping mechanism 200. The above design makes the wire automatic film wrapping mechanism 200 safer during operation and avoids unnecessary accidents.

[0057] The locking unit 281 includes a locking drive unit and a locking end. The locking drive unit is used to drive the locking end. The locking end can be plugged into the rotating film wrapping fixture 230, so as to achieve selective fixation of the rotating film wrapping fixture 230. Specifically, the locking drive unit is a locking cylinder. The locking unit 281 is a conventional structure in the art, and its working principle and specific structure are common knowledge in the art, and are well known to those skilled in the art, so no further description is given here.

[0058] Exemplarily, a protective film roll 800 is installed on the feeding module, and the feeding module includes a film feeding assembly 270 and a cutting assembly 240 arranged on the film feeding assembly 270. A positioning piece is provided on the film feeding assembly 270, and the positioning piece selectively fixes part of the end of the protective film roll 800. The cutting assembly 240 separates the protective film from the end of the protective film roll 800.

[0059] The feeding module can automatically feed the protective film to the film feeding position of the rotating film wrapping fixture 230. Through the cooperation of the film feeding component 270 and the cutting component 240, the length of the film feeding and cutting can be controlled, so as to quantitatively control the size of the cut protective film, thereby realizing automatic feeding, precise cutting and accurate placement of the protective film. The above design improves work efficiency and reduces the difficulty and error rate of manual operation. The design of the positioning part selectively fixing the end of the protective film roll 800 reduces the risk of positional displacement of the end of the protective film roll 800, ensures the smooth cutting of the cutting component 240, ensures the smooth forming of the protective film, makes the feeding and wrapping of the protective film more accurate and efficient, ensures the success rate of the film wrapping operation, and improves the yield rate of the wire products.

[0060] Furthermore, the feeding module also includes a film pressing assembly 210 disposed on the film feeding assembly 270, and the film pressing assembly 210 selectively presses the end of the protective film roll 800 so that the end of the protective film roll 800 can be clamped between the film pressing assembly 210 and the positioning member.

[0061] The film pressing assembly 210 can selectively press against the end of the protective film roll 800 so that the end of the protective film roll 800 can be clamped between the film pressing assembly 210 and the positioning piece, thereby ensuring that the protective film remains in position during the cutting process, avoiding the impact of the cutting action on the end of the protective film roll 800, and improving the stability and yield of the protective film forming.

[0062] The film pressing assembly 210 includes a film pressing driving unit 212 and a film pressing end 211. The film pressing driving unit 212 is used to drive the film pressing end 211. The film pressing end 211 can be pressed against the end of the protective film roll 800, thereby achieving accurate positioning of the end of the protective film roll 800. Specifically, the film pressing driving unit 212 is a servo motor. The film pressing assembly 210 is a conventional structure in the art, and its working principle and specific structure are common knowledge in the art, and are well known to those skilled in the art, and will not be elaborated herein.

[0063] In this embodiment, the cutting assembly 240 includes two cutting knives, and the two cutting knives are used to cut the portion of the protective film roll 800 extending out of the positioning piece from both sides.

[0064] The two cutting knives of the cutting assembly 240 can accurately cut the part of the protective film roll 800 extending out of the positioning piece from both sides, so as to obtain a suitable length of the protective film. The above design makes the cutting of the protective film more accurate and convenient, reduces the waste of the protective film roll 800, and reduces the complexity of the cutting action.

[0065] Specifically, the two cutting knives of the cutting assembly 240 are respectively a first cutting knife 241 and a second cutting knife 242. The first cutting knife 241 has a first blade 2411 and a first cutting drive unit 2412. The first cutting drive unit 2412 is used to drive the first blade 2411. The first blade 2411 is used to cut the protective film from one side. The second cutting knife 242 has a second blade 2421 and a second cutting drive unit 2422. The second cutting drive unit 2422 is used to drive the second blade 2421. The second blade 2421 is used to cut the protective film from the other side. With the cooperation of the first blade 2411 and the second blade 2421, the two blades can cut oppositely. Specifically, the first cutting drive unit 2412 is a servo motor, and the second cutting drive unit 2422 is a servo motor. The cutting knife is a conventional structure in the art, and its working principle and specific structure are common knowledge in the art, and are well known to those skilled in the art, so no further description is given here.

[0066] Exemplarily, the film feeding assembly 270 can switch between a film pulling position and a material cutting position relative to the wrapping module, and the film pressing assembly 210 moves synchronously with the film feeding assembly 270. When the film feeding assembly 270 is located at the film pulling position, the wrapping module and the material feeding module are spaced apart. When the film feeding assembly 270 is located at the material cutting position, the protective film separated from the protective film roll 800 is located at the film feeding position.

[0067] The film feeding assembly 270 can switch between the film drawing position and the material cutting position relative to the wrapping module. The above design makes the film feeding process more flexible and helps to improve the feeding efficiency of the protective film. When the film feeding assembly 270 is in the film drawing position, the wrapping module and the feeding module are spaced apart, thereby avoiding position conflicts between the two, reducing the space occupied by the wire automatic film wrapping mechanism 200, and helping to achieve structural optimization design.

[0068] In this embodiment, the positioning member includes a film suction plate 271 , and the film suction plate 271 selectively absorbs the surface of the protective film roll 800 .

[0069] The film absorbing plate 271 is designed to selectively absorb the surface of the protective film roll 800, which ensures the stability and flatness of the protective film during the feeding process and helps to improve the quality of the film wrapping operation. The film absorbing plate 271 includes an absorption layer and an absorption unit. The absorption layer has a plurality of absorption holes. The absorption unit is arranged at the bottom of the absorption layer and has the same number as the absorption holes. Each absorption unit is used to absorb the end of the protective film roll 800 placed on the absorption layer through a corresponding absorption hole. The film absorbing plate 271 is a conventional structure in the art. Its working principle and specific structure are common knowledge in the art and are well known to technicians in the art, so they will not be elaborated here.

[0070] Specifically, when the film feeding assembly 270 is located at the film pulling position, the pressing block 234 presses the protective film roll 800 against the film suction plate 271 from one side, and the film suction plate 271 absorbs the protective film roll 800 from the other side to keep the protective film roll 800 flat, and then the protective film roll 800 is pulled out. The above process avoids the slipping of the protective film roll 800 and avoids the failure of pulling out the protective film roll 800.

[0071] In this embodiment, the rotating film wrapping fixture 230 is defined to rotate around the first direction X, and the protective film roll 800 is fed along the second direction Y. The first direction X and the second direction Y are perpendicular to each other and both are located in the horizontal plane. The two cutting knives reciprocate along the third direction Z, and the third direction Z is perpendicular to the horizontal plane; the plane where the positioning member is located is parallel to the horizontal plane, and the film pressing assembly 210 reciprocates along the third direction Z.

[0072] Furthermore, the film feeding assembly 270 also includes a film feeding drive unit 272 and a film feeding body 273, the film suction plate 271 is fixedly arranged on the film feeding body 273, and the film feeding drive unit 272 is used to drive the film feeding body 273 to reciprocate along the second direction Y. Specifically, the film feeding drive unit 272 is a servo motor. Through the above structural design, the layout optimization of the wire automatic film wrapping mechanism 200 is achieved, the risk of position conflict between the wrapping module and the feeding module is reduced, and the space occupied by the wire automatic film wrapping mechanism 200 is reduced, which helps to achieve structural optimization design.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
