Description

Technical Field

[0001] This application relates to the technical field of flat wire motors, and in particular to a cutting mechanism for the enameled paint skin of the flat wire of a motor for new energy vehicles. Background Art

[0002] During the assembly process of the flat wire motor of a new energy vehicle, it is necessary to straighten, remove the skin, cut, etc. the coiled flat wire through a flat wire processing device. The methods for quickly removing the enameled paint skin of the flat wire generally include two types: laser skin removal and mechanical skin removal. The method of laser skin removal usually irradiates the enameled paint skin of the flat wire with a high-energy laser beam generated by a laser generator, but charred paint skin will remain on the copper core of the flat wire. The method of mechanical skin removal usually uses a servo system to control a stamping die, and removes the paint skin outside the flat wire by stamping, ensuring that during the skin removal process, the tool head can quickly and effectively cut the insulating paint layer while minimizing damage to the copper core.

[0003] In the related art, the stamping die is installed on a frame. The stamping die includes a tool holder, a first template, and a second template. On one side of the tool holder close to the first template, two symmetric tool heads are fixedly connected. A cutting channel having the same width as the copper core of the flat wire is left between the two tool heads. The first template is provided with a wire passing groove for the flat wire to pass through and a first feed groove communicating with the wire passing groove and for the tool head to pass through. The second template is provided with a second feed groove for the tool head to pass through and corresponding to the upper feed groove. The tool holder is driven by a vertical servo press to drive the tool head to pass through from the (upper and lower / left and right) sides of the flat wire, thereby removing the paint skin of the flat wire.

[0004] In view of the above related art, in order to ensure the accuracy of skin removal cutting and prevent the tool head from damaging the copper core, the two tool heads on the stamping die are usually fixedly connected to the tool holder to prevent displacement. Therefore, the distance between the two tool heads is a fixed value, and thus only flat wires of the same model and style can be cut and skinned. When flat wires of different models need to be processed, the stamping die needs to be removed from the frame and a tool holder matching the flat wire specification needs to be replaced. Since the stamping die has many components, the disassembly and assembly process is relatively cumbersome. Utility Model Content

[0005] In order to improve the problem that the disassembly and assembly of the stamping die is relatively cumbersome, this application provides a cutting mechanism for the enameled paint skin of the flat wire of a motor for new energy vehicles.

[0006] The cutting mechanism for the enameled paint skin of the flat wire of a motor for new energy vehicles provided by this application adopts the following technical solution:

[0007] A cutting mechanism for the enameled paint skin of the flat wire of a motor for new energy vehicles includes an installation table surface and a vertical skin removal component and a horizontal skin removal component arranged side by side on the installation table surface;

[0008] The vertical wire stripping assembly includes a vertical stamping frame and a vertical stamping die disposed on the vertical stamping frame. A first quick-release structure for disassembling and assembling the vertical stamping die is provided on the vertical stamping frame.

[0009] The horizontal wire stripping assembly includes a horizontal stamping frame and a horizontal stamping die disposed on the horizontal stamping frame. A second quick-release structure for disassembling and assembling the horizontal stamping die is provided on the horizontal stamping frame.

[0010] By adopting the above technical solutions, the vertical wire stripping assembly is used to remove the paint on the left and right edges of the flat wire, and the horizontal wire stripping assembly is used to remove the paint on the upper and lower edges of the flat wire. The vertical wire stripping assembly and the horizontal wire stripping assembly are respectively equipped with the first quick-release structure and the second quick-release structure. When dealing with flat wires of different widths or thicknesses, the stamping dies of the corresponding assemblies can be quickly replaced without the need for cumbersome disassembly and assembly of the entire mechanism. The quick-release structure makes the disassembly and assembly of the stamping die simpler and faster, reduces the time required for replacing the die, improves production efficiency, and enables the mechanism to flexibly adapt to flat wires of different models and specifications. Since the vertical wire stripping assembly and the horizontal wire stripping assembly can respectively perform precise wire stripping on different sides of the flat wire, it helps to ensure the accuracy and consistency of the wire stripping process. The distance between the cutting heads of each assembly can be selected according to the size of the specific flat wire, so as to minimize the damage to the copper core during the wire stripping process.

[0011] Further, the vertical stamping die includes a vertical tool holder, an upper template, a lower template, and a first die holder disposed below the lower template. A first limit seat for inserting and mounting the first die holder is provided on the vertical stamping frame.

[0012] The first quick-release structure includes a first fixing plate abutted against one side of the first limit seat and a first quick-release rod passing through the first fixing plate. A first quick interface for inserting and fixing the first quick-release rod is provided on the first die holder.

[0013] By adopting the above technical solutions, the first limit seat and the first quick interface ensure the accurate positioning of the vertical stamping die during the installation process. When the vertical stamping die is inserted into the first limit seat, it can be automatically aligned and fixed, reducing the positioning error caused by human factors and improving the accuracy and consistency of the wire stripping process. The first quick-release structure enables the vertical stamping die to be quickly removed from or installed on the vertical stamping frame. When dealing with flat wires of different models, the operator only needs to operate the first quick-release rod to release or fix the die from the first limit seat, avoiding the cumbersome steps during the disassembly and assembly process, and improving production efficiency and flexibility.

[0014] Further, a first fixing screw is also passed through the first fixing plate, and the first fixing screw passes through the first fixing plate and is threadedly connected to the first die holder.

[0015] By adopting the above technical solution, the first fixing screw fixes the first die base on the first fixing plate through threaded connection, increasing the stability of the vertical stamping die on the vertical stamping machine frame, which is more reliable than a simple quick-release structure. The stable die fixing method can ensure that the die will not loosen or shift during high-speed stamping, improving the stability and precision of the peeling process and reducing safety accidents caused by die loosening or falling off.

[0016] Further, two symmetrically arranged vertical cutting heads are fixedly connected to the vertical tool holder on the side close to the upper template. A vertical cutting channel equal in width to the copper core of the flat wire is left between the two vertical cutting heads. A first obtuse-angle guiding groove for guiding the paint film incision is formed on the side of the vertical cutting head far from the connection with the vertical tool holder.

[0017] By adopting the above technical solution, a vertical cutting channel equal in width to the copper core of the flat wire is left between the two vertical cutting heads, ensuring that the cutting heads can accurately cut along the edge of the copper core during the peeling process, avoiding damage to the copper core, and at the same time ensuring the flatness of the edge of the peeled flat wire, which is beneficial to subsequent processing and use. When the cutting head contacts the flat wire and starts cutting, the first obtuse-angle guiding groove formed on the vertical cutting head can guide the incision direction of the paint film, enabling the paint film to be cut and peeled along a predetermined path, helping to reduce the resistance and friction during the cutting process, reducing the wear of the cutting head, and improving the peeling efficiency. The obtuse-angle guiding groove enables the cutting head to make a smooth transition during the cutting process, reducing the impact and damage to the copper core caused by sudden cutting in or out.

[0018] Further, the upper template has an upper-side feed slot for the vertical cutting head to pass through, the lower template has a lower-side feed slot for the vertical cutting head to pass through and corresponding to the upper-side feed slot. The first die base is provided with a first blanking slot corresponding to the lower-side feed slot and for the paint film to fall. The vertical stamping machine frame is provided with a first material receiving port communicating with the first blanking slot on the lower side. A first material receiving pipe is fixedly connected to the lower side of the vertical stamping machine frame at the position of the first material receiving port. A negative pressure pump body connected to the first material receiving pipe is provided below the installation tabletop, and a first pipeline hole for the first material receiving pipe to pass through is opened on the installation tabletop.

[0019] By adopting the above technical solution, the upper feed groove on the upper template and the lower feed groove on the lower template are accurately corresponding to the vertical cutter head, ensuring that the vertical cutter head can smoothly pass through the left and right sides of the flat wire during the skinning process and perform cutting along a predetermined path, reducing the resistance and vibration during the cutting process, and improving the skinning efficiency and accuracy. The first blanking groove opened on the first die base corresponds to the lower feed groove, so that the cut paint waste can directly fall into it. The first material receiving port and the first material receiving pipe on the lower side of the vertical stamping machine frame facilitate the further collection and treatment of the waste. The negative pressure pump body below the installation table is connected to the first blanking groove through the first material receiving pipe, and uses negative pressure suction to suck and collect the cut paint waste, avoiding the waste flying around during the production process and causing pollution to the equipment and the environment. The automated waste collection method reduces the trouble of manual cleaning.

[0020] Further, a first wire passing groove for the flat wire to pass through is opened on the upper template along the length direction of the flat wire near the lower template side. The vertical stamping machine frame is symmetrically provided with first supporting brackets for supporting the flat wire on both sides. A first horizontal hole for the flat wire to pass through and aligned with the first wire passing groove is opened on the first supporting bracket.

[0021] By adopting the above technical solution, the first wire passing groove opened on the upper template is aligned with the first horizontal holes on the first supporting brackets on both sides of the vertical stamping machine frame, forming a stable channel for the flat wire to smoothly pass through during the skinning process, ensuring the stability and accuracy of the flat wire during transmission, and avoiding cutting errors caused by the offset of the flat wire position. The first supporting bracket serves as a supporting point for the flat wire, enhancing the stability of the mechanism during the skinning process. The first wire passing groove and the first horizontal hole are accurately aligned, enabling the vertical cutter head to accurately cut to the predetermined position of the flat wire, that is, the junction of the copper core and the paint skin, reducing excessive damage to the copper core, and ensuring the flatness of the edge of the flat wire after skinning.

[0022] Further, the horizontal stamping die includes a horizontal tool holder, a front template, a rear template, and a second die base provided on the side of the rear template away from the front template. A second limiting seat for inserting and installing the second die base is provided on the horizontal stamping machine frame;

[0023] The second quick-release structure includes a second fixing plate abutted against the upper side of the second limiting seat and a second quick-release rod passing through the second fixing plate. A second quick interface for inserting and fixing the second quick-release rod is opened on the second limiting seat;

[0024] A second fixing screw is also passed through the second fixing plate. The second fixing screw passes through the second fixing plate and is threadedly connected to the second die base.

[0025] By adopting the above technical solution, the horizontal stamping die includes components such as a horizontal tool holder, a front template, a rear template, and a second die holder. These components are quickly installed and disassembled through a second quick-release structure, simplifying the die assembly process and making it more convenient and efficient when maintenance or die replacement is required, thereby improving production efficiency and flexibility. The second limit seat provides a stable support platform for the second die holder, ensuring the stability and accuracy of the die during the stamping process. The second quick-release structure is tightly connected to the second limit seat through a second fixing plate and a second quick-release rod, enhancing the overall stability of the die and reducing errors caused by vibration or impact. The cooperation of the second quick-release rod and the second quick interface realizes the quick locking and release of the die, improving the efficiency of die replacement. The second fixing screw, as an auxiliary fixing device, further enhances the connection strength between the die and the second die holder, ensuring that the die will not loosen or fall off due to excessive force during the stamping process.

[0026] Further, two symmetrically arranged horizontal cutting heads are fixedly connected to the horizontal tool holder on the side close to the front template. A horizontal cutting channel with the same thickness as the copper core of the flat wire is left between the two horizontal cutting heads. A second obtuse-angle guiding groove for guiding the paint film incision is provided on the side of the horizontal cutting head away from the connection with the horizontal tool holder.

[0027] By adopting the above technical solution, a horizontal cutting channel with the same thickness as the copper core of the flat wire is left between the two horizontal cutting heads, ensuring that the cutting head can cut along the thickness of the copper core during the cutting process, avoiding excessive damage to the copper core, protecting the integrity and electrical conductivity of the copper core, and ensuring the quality of the flat wire after peeling. When the cutting head contacts the flat wire and starts cutting, the second obtuse-angle guiding groove on the horizontal cutting head can guide the incision direction of the paint film, enabling the paint film to be cut and peeled along a predetermined path, reducing the resistance and friction during the cutting process, reducing the wear of the cutting head, and also protecting the copper core from impact and damage during the cutting process.

[0028] Further, the front template has a front-side feed slot for the horizontal cutting head to pass through, the rear template has a rear-side feed slot for the horizontal cutting head to pass through and corresponding to the front-side feed slot, the second die holder is provided with a second blanking slot corresponding to the rear-side feed slot and for the paint film to enter, a second material receiving port communicating with the second blanking slot is provided on one side of the horizontal stamping frame, a second material receiving pipe is fixedly connected to the horizontal stamping frame at the position of the second material receiving port, the second material receiving pipe communicates with the first material receiving pipe, and a second pipeline hole for the second material receiving pipe to pass through is provided on the installation table surface.

[0029] By adopting the above technical solutions, the front side feed groove on the front template corresponds precisely to the rear side feed groove on the rear template, providing a smooth cutting path for the horizontal cutter head, ensuring that the horizontal cutter head can smoothly pass through the upper and lower sides of the flat wire during the peeling process, and cutting along a predetermined path, thereby improving the cutting accuracy and efficiency. The second blanking groove on the second die base corresponds to the rear side feed groove, enabling the cut paint waste to directly fall into it, reducing the accumulation of waste inside the equipment, facilitating subsequent cleaning. The second material receiving pipe is connected to the first material receiving pipe, enabling the waste to be exported outside the equipment for centralized treatment of the paint waste.

[0030] Further, a second wire passing groove for the flat wire to pass through is formed on the front template along the length direction of the flat wire near the side close to the rear template. Second support brackets for supporting the flat wire are symmetrically arranged on both sides of the horizontal stamping frame, and second level holes for the flat wire to pass through and aligned with the second wire passing groove are formed on the second support brackets.

[0031] By adopting the above technical solutions, the second wire passing groove formed on the front template is aligned with the second level holes on the second support brackets on both sides of the horizontal stamping frame, ensuring that the flat wire can maintain a stable position and posture when passing through the horizontal cutter head for cutting, avoiding cutting errors caused by vibration or deviation. The alignment of the second wire passing groove and the second level holes enables the flat wire to accurately pass through the cutting area of the horizontal cutter head during the cutting process, reducing the deviation during the cutting process, improving the cutting accuracy and consistency, and ensuring the edge flatness and dimensional accuracy of the flat wire after peeling.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The vertical peeling assembly and the horizontal peeling assembly respectively adopt the first quick-release structure and the second quick-release structure to achieve the quick installation and disassembly of the die, enabling operators to quickly replace the corresponding stamping die when dealing with flat wires of different widths, thicknesses or models, without the need for cumbersome disassembly and assembly of the entire mechanism, improving production efficiency and flexibility, and reducing downtime and die replacement costs;

[0062] The implementation principle of the motor flat wire edge paint peeling mechanism of a new energy vehicle in an embodiment of the present application is as follows: The peeling mechanism includes a vertical peeling component 1 and a horizontal peeling component 2, which are installed side by side on the installation table 3. The vertical peeling component 1 is responsible for removing the paint on the left and right sides of the flat wire, and the horizontal peeling component 2 is responsible for removing the paint on the upper and lower sides of the flat wire.

[0063] The vertical stamping frame 11 drives the vertical stamping die 12 to work through the vertical servo press 112. The vertical stamping die 12 is composed of an upper template 122, a lower template 123, a vertical tool holder 121, a vertical tool head 1211, etc. A vertical cutting channel 1212 equal to the width of the flat wire copper core is formed between the two vertical tool heads 1211. When the flat wire passes through the first wire groove 1221, the vertical servo press 112 drives the first pressing member 113 to press down the vertical tool holder 121, so that the vertical tool heads 1211 sequentially enter the upper side feed groove 1222 and the lower side feed groove 1231, and remove the paint from the left and right sides of the flat wire. During the cutting process, the first obtuse angle guiding groove 1213 guides the direction of the paint incision, ensuring a smooth cutting process and reducing damage to the copper core. The cut paint waste falls into the first material dropping groove 1241 through the lower side feed groove 1231, and is discharged from the first receiving port 1111, and finally collected and processed through the first receiving pipe 114.

[0064] The horizontal stamping frame 21 drives the horizontal stamping die 22 to work through the horizontal servo press 212. The horizontal stamping die 22 consists of a horizontal tool holder 221, a front template 222, a rear template 223, a horizontal tool head 2211, etc. A horizontal cutting channel 2212 equal to the thickness of the flat copper core is formed between two horizontal tool heads 2211. When the flat wire passes through the second wire passing groove 2221, the horizontal servo press 212 drives the second pressing member 213 to press against the horizontal tool holder 221, so that the horizontal tool heads 2211 sequentially enter the front side feed groove 2222 and the rear side feed groove 2231, and remove the paint film from the upper and lower sides of the flat wire. During the cutting process, the second obtuse angle guiding groove 2213 plays a role in guiding the direction of the paint film incision. The cut paint film waste falls into the second blanking groove 2241 through the rear side feed groove 2231, and is discharged through the second material receiving port 2111, and finally communicates with the first material receiving pipe 114 through the second material receiving pipe 214 for joint collection and treatment.

[0065] The vertical paint stripping assembly 1 and the horizontal paint stripping assembly 2 are respectively disassembled and assembled quickly through the first quick disassembly structure 13 and the quick disassembly structure, which is convenient for operators to quickly disassemble, assemble or replace the die to meet the processing requirements of flat wires with different widths, thicknesses or models. The quick disassembly structure cooperates with the quick interface on the limit seat through the quick disassembly rod to realize the quick locking and release of the die, and is supplemented by a fixing screw for auxiliary fixation to ensure the stability and accuracy of the die during the stamping process.

[0066] The cutting mechanism is also equipped with a waste collection system. Through the first material receiving pipe 114 and the second material receiving pipe 214 connected to the negative pressure pump body 4, the cut paint film waste is automatically collected and treated, avoiding pollution to the production environment and equipment, and improving production efficiency and cleanliness.

[0067] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
