Description

Technical Field

[0002] The shell-type temperature fuse is composed of two pins connecting a section of fusible alloy wire, which is wrapped by a special resin. When the temperature rises to a predetermined temperature, the fusible alloy melts and shrinks into a spherical shape under the action of the special resin, thereby cutting off the current.

After sleeving, it is also necessary for workers to heat-shrink the insulating tube through a hot air gun or an oven. However, since it is a temperature fuse itself, there is a risk of abnormal open circuit of the temperature fuse or thinning of the alloy wire after being heated at a high temperature by the hot air gun or the oven, resulting in abnormal failure risks such as premature open circuit when the product is in use; and the working size of the sleeving equipment is limited, which cannot meet the needs of customers for different specifications and sizes, and manual production operations are still required, and automated production cannot be achieved.

[0042] Embodiment

[0043] As Figures 1 to 8 shown, an automatic wire stripping device for three-layer insulated wire includes an operating table 2, on which a feeding component 3, at least two wire pressing components 4 and at least two wire stripping components 5 are installed; the feeding component 3 includes a feeding unit 31 and a discharging unit 32 symmetrically distributed on the same straight line, and a driving unit 33 respectively connected to the feeding unit 31 and the discharging unit 32. There is a mounting plate 34 fixed to the operating table 2 between the feeding unit 31 and the discharging unit 32. The mounting plate 34 is fixedly connected with a placing plate 35, and the mounting plate 34 and the placing plate 35 are perpendicular to each other; the wire pressing component 4 is fixedly installed on the mounting plate 34, and the wire pressing component 4 includes a pressing block 41 for cooperating with the placing plate 35 to press and a sliding block 42 fixedly connected to the pressing block 41; the wire stripping component 5 is arranged on one side of the placing plate 35, and the wire stripping component 5 includes a fixing plate 51, upper blades 52 and lower blades 54 which are symmetrically distributed up and down and slidably arranged on one side of the fixing plate 51 for automatic wire stripping, and an adjusting member 58 fixedly arranged on the other side of the fixing plate 51 for driving the fixing plate 51 to expand and contract left and right; wherein, the wire pressing component 4 is arranged above the placing plate 35, the pressing block 41 corresponds to the upper blades 52 and the lower blades 54, and the feeding unit 31, the placing plate 35 and the discharging unit 32 are arranged on the same straight line.

[0044] Specifically, including but not limited to, by Figure 1 shown, the wire stripping device includes a frame 1, the operating table 2 is fixedly installed in the frame 1, and the bottom of the frame 1 is also provided with a sliding wheel and a foot rod for supporting and positioning, which improves the flexibility of the device, and an operation screen and an alarm device are also arranged on the frame 1, so that the device can be automatically regulated.

[0045] Specifically, including but not limited to, after the driving unit 33 drives the three-layer insulated wire in a tape to enter along the feeding unit 31, it is squeezed and fixed by the wire pressing component 4, and then wire stripping is performed by the wire stripping component 5. There are two wire stripping components 5 and two wire pressing components 4, and two wire stripping areas are formed by the mutual cooperation of two wire stripping components 5 and two wire pressing components 4. They are installed in the order of the wire stripping component 5, the wire pressing component 4, the wire pressing component 4 and the wire stripping component 5, and the two wire stripping components 5 are respectively arranged on the left and right sides of the placing plate 35, so that the three-layer insulated wire undergoes two wire stripping processes and is discharged from the discharging unit 32 after wire stripping. Of course, in this embodiment, it is processed through a production line on the operating table 2. In some embodiments, the device can also be set as multiple production lines in parallel on the operating table 2 according to actual production requirements, which greatly increases the production efficiency of the device and the rationality of the use of the device space.

[0046] Specifically, including but not limited to, in this embodiment, the mounting plate 34 is in a cross structure, and an opening is provided corresponding to the placement plate 35, so that the placement plate 35 vertically passes through the opening. At the same time, a plurality of notches corresponding to the wire stripping assembly 5 are provided on the placement plate 35 to prevent the wire stripping assembly 5 from bumping against the prevention plate when moving left and right. In addition, a plurality of limiting plates are installed on both sides above the placement plate 35 to prevent the three-layer insulated wire from running off on the placement plate 35, effectively preventing accidents of the equipment. It should be noted that the two wire pressing assemblies 4 are respectively installed at the diagonal corners of both side surfaces of the mounting plate 34. At this time, each wire pressing assembly 4 further includes a sliding structure fixedly connected to the mounting plate 34 and a cylinder installed above the sliding structure. When the cylinder presses down or rises, the sliding block 42 can move up and down within the sliding structure. The pressing block 41 is fixedly installed at the end of the sliding block 42, so as to press or loosen the three-layer insulated wire under the drive of the sliding block 42. It is necessary to meet the requirement that the pressing block 41 protrudes from the end of the sliding block 42, and the pressing block 41 can be a wear-resistant rubber block to ensure the service life and pressing effect of the pressing block 41.

[0047] Through the above solution, the production cost is reduced, the requirements of customers for different sizes are met, and high-efficiency automated production is achieved.

[0048] As a specific improved embodiment, the adjusting member 58 includes a first telescopic block 581, a second telescopic block 582 slidably connected to the first telescopic block 581, and a connecting block 583 slidably connected to the second telescopic block 582. The first telescopic block 581 is fixedly connected with a first driving member 584. The connecting block 583 is provided with a fine-tuning knob 585, and the connecting block 583 is fixedly connected to the operating table 2.

[0049] Specifically, including but not limited to, between the adjusting member 58 and the fixing plate 51, there is a triangular fixing block. The triangular fixing block is fixedly connected to the first telescopic block 581. The first telescopic block 581, the second telescopic block 582, and the connecting block 583 are assembled in sequence from top to bottom. And there is a sliding structure between the first telescopic block 581 and the second telescopic block 582, and between the second telescopic block 582 and the connecting block 583, so that the first telescopic block 581 can slide relative to the second telescopic block 582, and the second telescopic block 582 can slide relative to the connecting block 583. And the end of the connecting block 583 is fixed to the operating table 2. Based on this, when the first telescopic block 581 or the second telescopic block 582 moves telescopically, it can drive the movement of the fixing plate 51, thereby adjusting different wire stripping lengths to meet the needs of different customers; the first driving member 584 can be a cylinder, which is fixedly installed at the end of the first telescopic block 581 to provide the sliding power for the first telescopic block 581 and the second telescopic block 582. At the same time, a fine-tuning knob 585 is fixedly installed on the connecting block 583. The fine-tuning knob 585 is arranged below the second telescopic block 582. Correspondingly, a locking member is also arranged in cooperation with the fine-tuning knob 585. The fine-tuning knob 585 is mainly used for finely adjusting the moving distance of the second telescopic block 582. The fine-tuning knob 585 is a micrometer knob. Thus, after the first telescopic block 581 moves and pushes the fixing plate 51 to a specified position, further fine adjustment is carried out through the fine-tuning knob 585 to reach the specified precise position. After reaching the specified position, the locking member locks and fixes the second telescopic block 582. On the one hand, it can ensure locking after precise positioning. On the other hand, at this time, only the reciprocating movement of the first telescopic block 581 is required to drive the fixing plate 51, and the second telescopic block 582 does not need to move telescopically anymore, which can reduce energy consumption.

[0050] Through the above solution, under the drive of the first driving member 584, the first telescopic block 581 and the second telescopic block 582 can reciprocate relative to the connecting block 583, ensuring the accuracy and adjustment of the automatic wire stripping of the equipment. At the same time, the connecting block 583 is installed with a fine-tuning knob 585 for adjusting the precise wire stripping length, further improving the accuracy of the wire stripping length and ensuring the quality of the triple-insulated wire.

[0051] As a specific implementation of the improvement, the range of the transverse telescopic movement of the fixing plate 51 along the operating table 2 is 20mm - 80mm.

[0052] Specifically, including but not limited to, the fixing plate 51 moves horizontally and telescopically along the operating table 2, so that it can extend into or out of the notch of the placing plate 35. The left - right movement range of the fixing plate 51 is 20mm - 80mm, that is, the moving distance of the fixing plate 51. Based on this, the adjustment range of the adjusting part 58 is 20mm - 80mm. Therefore, the workable wire length of the wire stripping assembly 5 for stripping the three - layer insulated wire can be adjusted within the range, and it can adapt to the three - layer insulated wires with different wire stripping length requirements. Of course, in some embodiments, the range can also be changed according to different requirements. Since the operating table 2 is provided with multiple through - holes and the wire stripping assembly 5 is accommodated at the through - holes, at this time, only by changing the length and other dimensions of the through - holes, as well as the moving lengths of the first telescopic block 581 and the second telescopic block 582 relative to the sliding structure, the range can be increased or decreased, which can further improve the adaptability and practicability of the equipment. It should be noted that in this embodiment, two wire stripping assemblies 5 are provided and their working lengths are the same. Among them, the working lengths of the two wire stripping assemblies 5 can also be set to be different, and their automatic controls do not affect each other, which can meet a greater market demand.

[0053] Through the above - mentioned solution, the workable wire length of the equipment can be arbitrarily adjusted within the range, that is, the wire stripping length is adjusted according to the length requirements of different three - layer insulated wires, which improves the intelligence and flexibility of the equipment.

[0054] As a specific improved embodiment, the upper blade 52 is fixedly connected with a first sliding block 53 for driving the upper blade 52 to move up and down, and the lower blade 54 is fixedly connected with a second sliding block 55 for driving the lower blade 54 to move up and down.

[0055] Specifically, including but not limited to, a sliding structure is arranged on the side surface of the fixing plate 51 facing the wire pressing assembly 4. The first sliding block 53 and the second sliding block 55 can move up and down along the fixing plate 51. The fixing plate 51 is vertically arranged, and cylinders are fixedly installed at both the upper and lower ends of the fixing plate 51. The two cylinders respectively drive the first sliding block 53 and the second sliding block 55, so that the first sliding block 53 and the second sliding block 55 can move vertically. There are multiple sliding blocks in the sliding structure, and the first sliding block 53 and the second sliding block 55 are fixedly connected with the sliding blocks. At this time, the upper blade 52 is embedded in the side surface of the first sliding block 53, and the lower blade 54 is embedded in the side surface of the second sliding block 55. The first sliding block 53 and the second sliding block 55 are both rectangular structures, and the side surfaces of the upper blade 52, the lower blade 54, the first sliding block 53 and the second sliding block are on the same horizontal plane. It should be noted that in this embodiment, both the upper blade 52 and the lower blade 54 are detachable structures, so that the blades can be replaced or maintained, realizing the quick disassembly and assembly of the upper blade 52 and the lower blade 54. Of course, in some embodiments, the first sliding block 53 and the upper blade 52, the second sliding block 55 and the lower blade 54 can also be set as an integral structure, which is convenient for the processing and production of components.

[0056] Through the above solution, the first sliding block 53 drives the upper blade 52 to move up and down, and the second sliding block 55 drives the lower blade 54 to move up and down, enabling automatic wire stripping of the three-layer insulated wire.

[0057] As a specific embodiment of the improvement, the wire stripping interval after the upper blade 52 and the lower blade 54 are vertically telescoped and closed along the fixed plate 51 is 1 mm - 20 mm.

[0058] Specifically, including but not limited to, the fixed plate 51 is vertically arranged, and there is a sliding structure on its side. The first sliding block 53 and the second sliding block 55 can reciprocate up and down along the fixed plate 51 under the drive of the upper cylinder and the lower cylinder, that is, both the upper blade 52 and the lower blade 54 can move up and down telescopically. Based on this, when the upper blade 52 and the lower blade 54 are pushed by the cylinder to close the blades for wire stripping operation, the lower knife depth of the blade can be adjusted through the cylinder on the wire stripping assembly 5, mainly by adjusting the positions of the upper blade 52 and the lower blade 54. Then, of course, the sliding distance of the sliding structure can also be adjusted outside the wire stripping interval of 1 mm - 20 mm according to actual needs to adapt to more wire stripping depth dimensions. It should be noted that in this embodiment, two wire stripping assemblies 5 are provided and the wire stripping depths are the same. Among them, the two wire stripping depths can also be set to be different, and their automatic controls do not affect each other, which can meet greater market demands.

[0059] Through the above solution, the lower knife depth of the upper blade 52 and the lower blade 54 can be adjusted arbitrarily within a certain range to adapt to the wire stripping depth requirements of different three-layer insulated wires, improving the adaptability and flexibility of equipment production.

[0060] As a specific embodiment of the improvement, a guide tube 56 is connected to the bottom end of the second sliding block 55, and a wire collecting cylinder is arranged below the guide tube 56.

[0061] Specifically, including but not limited to, the guiding tube 56 is a hollow rectangular tube. The second sliding block 55 has a cavity inside, and there are an inlet and an outlet for the circulation of the wire skin recovery at both ends connecting the cavity. The inlet and the outlet are symmetrically distributed up and down. The upper end of the lower blade 54 is close to the inlet, so that the wire skin falls into the inlet after being peeled off. And a convex bulge is provided at the bottom of the first sliding block 53 corresponding to the inlet. A groove is provided at the center of the convex bulge, and a plurality of small pushing cylinders for pushing and pressing the wire skin are installed in the groove. The small pushing cylinders correspond to the cutting edges 542, and the convex bulge is of a U-shaped structure with its notch facing the upper blade 52. The convex bulge corresponds to the inlet. When the first sliding block 53 and the second sliding block 55 are attached, the convex bulge can be embedded into the inlet. Based on this, on the one hand, it can prevent the wire skin from falling into the equipment, and on the other hand, it can provide enough space to satisfy the wire skin falling into the cavity after being peeled off. A receiving bucket 57 is placed below the guiding tube 56. The receiving bucket 57 is placed in the frame 1, and a door body is installed at the position of the frame 1 corresponding to the receiving bucket 57 for easy taking or placing of the receiving bucket 57. At the same time, the receiving bucket 57 can be placed on a pressure sensor, and an alarm is issued when the pressure exceeds a certain value, so that it can be cleaned in time to avoid the wire skin overflowing from the receiving bucket 57. Then, when the three-layer insulated wire is automatically stripped by the upper blade 52 and the lower blade 54, the wire skin falls off under the pressing action of the small pushing cylinders after being peeled off. And the small pushing cylinders are also connected with air inlets to automatically clean the wire skin remaining on the cutting edges 542. The wire skin passes through the inlet, the cavity, the outlet in sequence and then enters the guiding tube 56, and thus falls into the receiving bucket 57 to complete the wire skin recovery.

[0062] Through the above solution, the wire stripping assembly 5 can automatically collect the waste wire skin of the stripped wire, ensure the normal operation of the equipment, and uniformly process the recovered wire skin to avoid environmental pollution.

[0063] As a specific embodiment of the improvement, both the upper blade 52 and the lower blade 54 are provided with mutually meshing cutter teeth 541, and a plurality of cutting edges 542 are provided on the cutter teeth 541.

[0064] Specifically, including but not limited to, both the upper blade 52 and the lower blade 54 are set as rectangular structures. The cutter teeth 541 are arranged on the narrow sides of the upper blade 52 and the lower blade 54. The cutter teeth 541 are of a V-shaped tooth structure. In this embodiment, the cutter teeth 541 are provided with 4 V-shaped teeth, and thus the stripping operation of 4 three-layer insulated wires can be carried out simultaneously. Of course, the structure of the cutter teeth 541 can also be optimized according to the actual production requirements and equipment requirements to improve the production efficiency and product quality of the equipment. The cutting edges 542 are the openings of the V-shaped teeth. The bottom connection of the cutting edges 542 of the lower blade 54 is set as an arc structure. When the cutter teeth 541 of the upper blade 52 and the lower blade 54 are meshed, the arc structure of the cutting edges 542 just corresponds to the three-layer insulated wire, which can cut off more wire skin and improve the precision and quality of wire stripping.

[0065] Through the above solution, the setting of the cutting teeth 541 enables the device to automatically strip multiple three-layer insulated wires simultaneously. Meanwhile, the arc-shaped structure of the cutting edge 542 can increase the contact area between the upper blade 52 and the lower blade 54 with the three-layer insulated wire respectively, that is, it can cut more wire skins and ensure the rapid peeling of the wire skins.

[0066] As a specific embodiment of the improvement, the driving unit 33 is fixedly installed under the operation table 2. The driving unit 33 includes a second driving member 331 and a rotating member 332 rotatably connected to the second driving member 331. First rotating members 333 and second rotating members 334 are fixedly installed at both ends of the rotating member 332 respectively. The first rotating member 333 is rotatably connected to the feeding unit 31, and the second rotating member 334 is rotatably connected to the discharging unit 32.

[0067] Specifically, including but not limited to, the driving unit 33 is fixedly installed at the bottom of the operation table 2. The second driving member 331 is a cam divider, and the rotating member 332 is the output shaft of the second driving member 331. First rotating members 333 and second rotating members 334 are fixedly sleeved at both ends of it. Both the first rotating member 333 and the second rotating member 334 are runner wheels. Thus, when the rotating member 332 rotates under the drive of the second driving member 331, it drives the first rotating member 333 and the second rotating member 334 to rotate in the same direction. As a result, after the three-layer insulated wire enters from the feeding unit 31, it is led out from the discharging unit 32 through the placing plate 35.

[0068] Through the above solution, the cooperation between the second driving member 331 and the rotating member 332 can provide rotation in the same direction, ensuring the feeding unit 31 and the discharging unit 32 move in the same direction to complete automatic feeding.

[0069] As a specific embodiment of the improvement, the feeding unit 31 or the discharging unit 32 includes a toothed wheel 321, a guide wheel 322 arranged in cooperation with the toothed wheel 321, and a traction belt 323 linked to one end of the toothed wheel 321. The traction belt 323 is connected to the first rotating member 333 or the second rotating member 334.

[0070] Specifically, including but not limited to, the feeding unit 31 or the discharging unit 32 further includes two fixing blocks that can fixedly install the toothed wheel 321 on the operating table 2. The two fixing blocks are vertically arranged with a distance between them. The toothed wheel is placed between the two fixing blocks, and then a transmission shaft passes through the toothed wheel 321 and the fixing blocks. A runner is installed at one end of the transmission shaft protruding from the fixing block. At this time, the runner and the transmission shaft are fixedly connected. Then, the first rotating member 333 or the second rotating member 334 and the toothed wheel 321 can be connected through the traction belt 323, so that the first rotating member 333 and the toothed wheel 321 are linked to realize the rotation of the toothed wheel 321. And the toothed wheel 321 is a V-shaped gear structure, and the three-layer insulating wire can be accommodated in the toothed wheel 321 and initially positioned. The guide wheel 322 and the toothed wheel 321 are parallel to each other. The guide wheel 322 is fixedly connected with an adjusting shaft, and the adjusting shaft is fixedly connected with the fixing block. The guide wheel 322 can squeeze the three-layer insulating wire into the toothed wheel 321 when it enters, so as to guide the three-layer insulating wire in a specified direction during the movement process, ensuring that the three-layer insulating wire can move along a predetermined path. Here, it should also be noted that the feeding unit 31 may also include a sensor, which is fixedly installed on the operating table 2 and can collect information about the three-layer insulating wire.

[0071] Through the above solution, the equipment can realize automatic feeding and discharging, and the guide wheel 322 can accurately position the movement direction according to different three-layer insulating wires, ensuring the stability and accuracy of the equipment.

[0072] As a specific implementation of the improvement, the discharging unit 32 further includes a guiding member 324 for guiding the traction belt 323. The guiding member 324 is arranged between the second rotating member 334 and the toothed wheel 321.

[0073] Specifically, including but not limited to, based on the feeding unit 31 being arranged at one end of the operating table 2 and the discharging unit 32 being arranged at the other end of the operating table 2, and the driving unit 33 being fixedly installed at the bottom of the operating table 2 corresponding to the lower part of the feeding unit 31. Then, the guiding belt of the feeding unit 31 can directly pass through the through hole of the operating table 2 and be connected to the first rotating member 333. For the discharging unit 32, a guiding member 324 needs to be set. The guiding member 324 is arranged close to the discharging unit 32 and is fixedly installed under the operating table 2. The guide wheel 322 can limit the traction belt 323, thereby changing the traction angle formed by the connection between the traction belt 323 and the second rotating member 334 or the toothed wheel 321, avoiding the scraping of the traction belt 323, and thus improving the service life.

[0074] Through the above solution, the setting of the guiding member 324 can ensure the synchronous linkage of the second rotating member 334 and the toothed wheel 321 of the discharging unit 32.

[0075] Workflow:

[0076] First, after the three-layer insulated wire with the tape is induced by the inductor, the drive unit 33 is started, and the gear shaft rotates to send the three-layer insulated wire into the wire-passing track of the placement plate 35 to complete automatic feeding and wire-in. Then, the cylinder of the previous wire-pressing assembly 4 presses down, and the three-layer insulated wire is pressed tightly by the pressing block 41. Then, the previous wire-stripping assembly 5 strips the wire on the left side of the three-layer insulated wire. At this time, the first driving member 584 of the adjusting member 58 pushes the fixing plate 51 forward to reach the specified wire-stripping position adjusted in advance, and then fine-tunes through the fine-tuning button. Then, the upper blade 52 moves downward driven by the first sliding block 53, and the lower blade 54 moves upward driven by the second sliding block 55 to complete the closing of the blades for wire-stripping operation. The wire skin enters the collection bucket 57 through the guide tube 56 for recycling.

[0077] Then, the same steps as above are carried out through the cooperation of the subsequent wire-pressing assembly 4 and the subsequent wire-stripping assembly 5. After pressing the three-layer insulated wire tightly, wire-stripping is carried out on the right side to complete all wire-stripping operations of the three-layer insulated wire.

[0078] Finally, after the processed three-layer insulated wire passes through the placement plate 35, the toothed wheel 321 of the discharging unit 32 rotates to complete automatic discharging.

[0079] Finally, it should be noted that the above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
