Description

Technical Field

[0001] The present application relates to the technical field of insulator production, and in particular to a production line for insulator products. Background Art

[0002] Insulator products are usually assembled from core rods, slender end fittings, silicone sheds and other accessories. During the assembly process of the core rods and end fittings, the existing technology usually adopts manual methods to coat and polish the core rods and fittings, and then manually assemble the two and move them to the crimping machine for crimping. Finally, they are injected to obtain the insulator products. Manual operation increases the time and labor costs of manufacturing, resulting in low production efficiency. Manual positioning of the crimping position is prone to problems with the core rod and end fitting not being properly fitted, resulting in excessive assembly dimensions and offset crimping positions, making it impossible to guarantee product quality. In addition, processes such as core rod coating and fitting coating in insulator production are also mostly manual operations, resulting in low production efficiency. Utility Model Content

[0028] like Figure 1 As shown, the present application provides a production line 10 for insulator products, including a crimping system 100, a coating system 200, a stripping system 300, and an injection system (not shown). The coating system 200 is used to coat the outer surface of the core rod or the inner surface of the metal fitting at the coating station; the stripping system 300 is used to strip the crimping surface of the metal fitting at the stripping station; the crimping system 100 is used to perform sleeve connection and crimping operations on the core rod and the metal fitting at the crimping station, Figure 7 The crimping system 100 includes a crimping machine 110, a positioning mechanism 130, and a support platform 120, which are arranged in sequence. The support platform 120 is used to support and move the core rod and hardware. The positioning mechanism 130 is used to move against the hardware to be socketed during the socketing operation. The support platform 120 and the positioning mechanism 130 cooperate to socket the hardware onto the end of the core rod. The crimping machine 110 is used to crimp the hardware socketed onto the core rod to obtain an insulator preform. The injection system is used to perform injection molding on the insulator preform at the injection station, injection-molding sheds around the outer periphery of the core rod to obtain the insulator product. The coating station and stripping station are located upstream of the crimping station, and the injection station is located downstream of the crimping station.

[0029] The production line 10 in this application is mainly used to produce insulator products. The production line 10 can adjust some parameters according to actual production requirements, such as the length of the insulator product, the cross-sectional specifications of the core rod, the crimping position of the hardware, the structure of the umbrella skirt, etc.

[0030] The production line 10 further includes a conveyor mechanism 20 for moving core rods, hardware, insulator preforms, or insulator products between workstations. The conveyor mechanism 20 can be an automated device such as a robotic arm, providing flexible placement and high flow efficiency.

[0031] like Figure 2 As shown, the coating system 200 includes a core rod coating device 400, and the core rod coating device 400 includes a core rod coating mechanism 410, a core rod loading mechanism 420 and a core rod drying mechanism 430. The core rod loading mechanism 420 is used to load the core rod; the core rod coating mechanism 410 is arranged on the core rod loading mechanism 420, and is used to coat the outer surface of the core rod after loading; the core rod drying mechanism 430 is arranged on the core rod loading mechanism 420, and is used to dry the core rod after coating.

[0032] The mandrel loading mechanism 420 includes a mandrel moving assembly 421, a mandrel loading rack 422, and a mandrel lifting assembly 423. The mandrel moving assembly 421 is used to move the mandrel; the mandrel loading rack 422 is arranged on one side of the mandrel moving assembly 421, and is used to place the mandrel; the mandrel lifting assembly 423 is arranged at the bottom of one end of the mandrel loading rack 422 close to the mandrel moving assembly 421, and can partially extend out of the upper surface of the mandrel loading rack 422, and is used to lift the mandrel onto the mandrel moving assembly 421.

[0033] The core rod moving assembly 421 includes a conveying platform 4211, a conveying guide rail 4212, a conveying drive 4213, a conveying assembly (not shown), and a conveying seat 4214. The conveying guide rail 4212 is arranged on the conveying platform 4211; the conveying seat 4214 is slidingly connected to the conveying guide rail 4212, and at least two conveying supports are arranged on the conveying seat 4214 at intervals for supporting the core rod. The position of the conveying support is adjustable to meet the support requirements of core rods of more length specifications and expand the application range of the equipment; the conveying drive 4213 is arranged at one end of the conveying guide rail 4212; the conveying assembly is arranged at the bottom of the conveying seat 4214, and the conveying assembly is connected to the power output end of the conveying drive 4213 for transmitting the power of the conveying drive 4213 to the conveying seat 4214, so as to control the movement of the conveying seat 4214 on the conveying guide rail 4212.

[0034] The core rod loading rack 422 includes a fixed plate 4221, a loading plate 4222 and a stopper 4223. The two fixed plates 4221 are arranged relative to each other in the vertical direction on the conveying platform 4211. The loading plate 4222 is mounted in the middle of the two fixed plates 4221, and the loading plate 4222 is tilted downward toward the core rod moving assembly 421. The end of the loading plate 4222 with a higher horizontal height is defined as the loading port, and the other end is the discharge port. The tilted loading plate 4222 facilitates the core rod to move quickly from the loading port to the discharge port, thereby improving the loading efficiency; a number of stoppers 4223 are spaced apart at the end of the loading plate 4222 with a lower horizontal height to prevent the core rod from falling.

[0035] The core rod lifting assembly 423 includes a connected lifting cylinder and a lifting plate (not shown in the figure). A hollow area corresponding to the lifting plate is provided at the discharge port of the loading plate 4222. The lifting cylinder can drive the lifting plate to move upward in the vertical direction and pass through the hollow area. The maximum moving height of the lifting plate is higher than the height of the stopper 4223, so as to lift the core rod close to the stopper 4223 on the loading plate 4222 to the top of the stopper 4223, so as to facilitate the movement of the core rod to the conveying seat 4214 of the core rod moving assembly 421.

[0036] Furthermore, to facilitate the mandrel lifting assembly 423 in lifting and moving the mandrel from the mandrel loading rack 422 to the mandrel moving assembly 421, the stopper 4223 is an inclined block-shaped structure, and its upper surface is tilted downward toward the mandrel moving assembly 421. This facilitates the mandrel to quickly move along the upper surface of the stopper 4223 to the mandrel moving assembly 421 after being lifted. The inclination angle and specific dimensions of the upper surface of the stopper 4223 can be adjusted according to the relative position between the stopper 4223 and the conveying base 4214, and are not specifically limited here as long as they can guide the lifted mandrel and do not affect the movement of the mandrel by the mandrel moving assembly 421.

[0037] Furthermore, the mandrel feeding mechanism 420 also includes an auxiliary lifting assembly 424 for guiding the mandrel lifted by the mandrel lifting assembly 423 to the mandrel moving assembly 421. The auxiliary lifting assembly 424 includes an auxiliary moving assembly 4241, an auxiliary fixing plate 4242, a guide rod 4243 and a guide plate 4244. The two guide rods 4243 are arranged horizontally and parallel to each other. The guide rods 4243 are mounted on the upper parts of the two fixing plates 4221 and are respectively located near the loading port and the discharging port; the auxiliary fixing plate 4242 is arranged vertically and penetrates the two guide rods 4243 so that the auxiliary fixing plate 4242 can move along the guide rods 4243; the guide plate 4244 is arranged on the auxiliary fixing plate 4242 At one end of the mandrel moving assembly 421, the surface of the guide plate 4244 is tilted downward toward the mandrel moving assembly 421, and the surface height of the guide plate 4244 is higher than the stopper 4223 and the conveying seat 4214. On the one hand, it can limit the maximum height of the mandrel jacking to prevent the mandrel jacking assembly 423 from jacking the mandrel too high and causing it to fall. On the other hand, it can play a certain guiding role in the moving path of the mandrel after jacking; the auxiliary moving assembly 4241 is set on one of the fixed plates 4221, and can drive the auxiliary fixed plate 4242 to move along the guide rod 4243 to adjust the position of the guide plate 4244, so that it can play a limiting role for mandrels of more length specifications, thereby expanding the application range of the equipment. The inclination angle, specific size and height of the guide plate 4244 can be adjusted according to the relative position between the guide plate 4244 and the conveying seat 4214. For example, the inclination angle of the guide plate 4244 can be the same as the upper surface of the stopper 4223, and the height between the two is slightly larger than the cross-sectional specification of the core rod. The guide plate 4244 can extend to partially above the conveying seat 4214 to achieve better limiting and guiding effects, or other settings can be used. As long as it can limit and guide the core rod after jacking and does not affect the movement of the core rod by the core rod moving assembly 421, no specific restrictions are made here.

[0038] Combine Figure 3As shown, the mandrel coating mechanism 410 is arranged on the mandrel moving assembly 421 and is located above the middle of the mandrel moving path. The mandrel coating mechanism 410 includes a coating frame 411 and an operating assembly 412. The coating frame 411 includes a plurality of support rods 4111 and a top plate 4112. The plurality of support rods 4111 are vertically arranged on the conveying platform 4211 and distributed on both sides of the conveying guide rail 4212; the top plate 4112 is horizontally mounted on the plurality of support rods 4111 so that the top plate 4112 is located above the conveying guide rail 4212, that is, above the mandrel moving path; the operating assembly 412 is arranged at the bottom of the top plate 4112 and is used to perform coating operations on the outer surface of the mandrel. The operating assembly 412 includes a claw driving member (Figure The two claws 4121 are arranged at the bottom of the top plate 4112 at relative intervals and are connected to the claw driving member. The claw driving member can drive the two claws 4121 to move toward each other to clamp the core rod; the water absorbing member is arranged on the inner side of the two claws 4121 close to each other, and is used to absorb the core rod coating agent. In the process of the claws 4121 clamping the core rod, the water absorbing member will also squeeze the core rod to release the core rod coating agent therein. After the claws 4121 clamp the core rod in place, the core rod moving assembly 421 can be used to control the core rod to move along the conveying guide rail 4212, so that the core rod coating agent squeezed out of the water absorbing member is used to coat the outer surface of the core rod.

[0039] Furthermore, the inner surfaces of the adjacent claws 4121 can be grooved. The matching grooves of the two claws 4121 have a profile that matches the cross-sectional shape and specifications of the mandrel. This allows the two claws 4121 to clamp the mandrel within the grooves, providing a more effective grip. This in turn increases the pressure exerted by the absorbent element on the mandrel, ensuring a successful coating operation. Furthermore, the claws 4121 are removable. When coating mandrels of different specifications, the corresponding claws 4121 can be quickly replaced, simplifying installation, increasing efficiency, and enhancing the versatility of the equipment.

[0040] Furthermore, the operating component 412 also includes a first raw material conveying component 4122, which is used to continuously provide raw materials to the water-absorbing component. The first raw material conveying component 4122 includes a raw material barrel, a pipeline and a peristaltic pump. The water-absorbing component is connected to the raw material barrel through a pipeline. The peristaltic pump can drive the pipeline to absorb raw materials from the raw material barrel and continuously convey them to the water-absorbing component, ensuring that the water-absorbing component is always filled with sufficient core rod coating agent to ensure the coating effect. There is no need to replace the water-absorbing component during the production process, making the production rhythm more compact and more efficient.

[0041] Furthermore, two operating assemblies 412 may be provided, spaced apart at the bottom of the top plate 4112 along the direction of movement of the mandrel. The operating assembly 412 proximal to the mandrel loading mechanism 420 is used to clean the outer surface of the mandrel, while the operating assembly 412 distal to the mandrel loading mechanism 420 is used to coat the outer surface of the mandrel, thereby preventing the coating effect from being affected by dirt, oil, or other stains on the outer surface of the mandrel. It is understood that the first material conveying assembly 4122 of the operating assembly 412 for cleaning delivers a cleaning agent to its absorbent member, while the first material conveying assembly 4122 of the operating assembly 412 for coating delivers a mandrel coating agent to its absorbent member. The absorbent member may be a sponge, for example, the cleaning agent may be a solvent such as alcohol, and the mandrel coating agent may be a coupling agent, for example.

[0042] Furthermore, to avoid wasting resources, the mandrel coating mechanism 410 further includes a reflux assembly 413 for collecting mandrel coating agent dripping during the coating operation or collecting cleaning agent dripping during the cleaning operation. The reflux assembly 413 includes a first reflux tray 4131 and a second reflux tray 4132. The first reflux tray 4131 is disposed below the coating operation assembly 412 and is used to collect mandrel coating agent dripping during the coating operation; the second reflux tray 4132 is disposed on the conveying seat 4214, and the conveying support is disposed on the second reflux tray 4132, so that the second reflux tray 4132 is located below the mandrel and is used to collect cleaning agent dripping during the cleaning operation. The first reflux tray 4131 and the second reflux tray 4132 are both tilted downward, with a reflux hole at their lower end. Each is connected to a corresponding raw material barrel via a pipe. This allows the collected cleaning agent or mandrel coating agent to quickly flow through the reflux hole and into the raw material barrel for recycling and reuse. This also prevents the collected raw materials from being exposed to air for a long time, causing them to deteriorate and affect the quality of the recycled raw materials. Furthermore, the reflux assembly 413 may include a reflux drive 4133, which is disposed on one side of the conveying platform 4211 and connected to the first reflux tray 4131. The reflux drive 4133 is used to drive the first reflux tray 4131 away from the mandrel coating mechanism 410 in a direction perpendicular to the direction of mandrel movement. When the gripper 4121 needs to be replaced or the first reflux tray 4131 needs to be disassembled for cleaning, the first reflux tray 4131 can be controlled to move away, facilitating assembly. The second reflux tray 4132 is detachably connected to the conveying base 4214 and the conveying support, facilitating assembly.

[0043] Furthermore, the reflux assembly 413 also includes two auxiliary reflux trays 4134, which are respectively arranged on both sides of the conveying guide rail 4212, and are used to collect liquid that drips during the coating operation or cleaning operation on the core rod and is not collected by the first reflux tray 4131 and the second reflux tray 4132, so as to prevent it from dripping directly onto the conveying platform 4211 and polluting the operating environment.

[0044] The mandrel drying mechanism 430 is disposed on the mandrel moving assembly 421, and the mandrel drying mechanism 430 and the mandrel loading rack 422 are respectively located on either side of the mandrel coating mechanism 410. This allows the mandrels to be loaded from the mandrel loading rack 422 onto the mandrel moving assembly 421, and after passing through the mandrel coating mechanism 410 to complete the coating operation, they are moved to the mandrel drying mechanism 430 for drying. This facilitates the sequential flow of mandrels for loading, coating, and drying operations, thereby improving production efficiency. The mandrel drying mechanism 430 includes a drying rack and a fan. The drying rack is disposed on one side of the conveying platform 4211, and the fan is disposed above the drying rack, with the fan's air outlet facing the mandrel moving assembly 421, thereby improving the drying efficiency of the mandrels.

[0045] Furthermore, the mandrel coating device 400 also includes several sensors for detecting whether there are mandrels at the target position, facilitating the monitoring of the flow of mandrels and avoiding costly waste caused by idling equipment. Sensors can be installed on the discharge port of the mandrel loading rack 422, the mandrel coating mechanism 410, and the mandrel drying mechanism 430. If a mandrel is detected at the corresponding position, the mandrel can be controlled to perform loading, coating, and drying operations. In addition, a sensor can be installed in the gap between the mandrel loading rack 422 and the outer side of the end of the mandrel moving assembly 421. If a mandrel is detected here, it indicates that the mandrel has fallen abnormally, and the sensor will issue a warning signal. The sensor can be a photoelectric sensor, an infrared sensor, etc., and is not specifically limited here.

[0046] like Figure 4 As shown, the coating system 200 also includes a fitting coating device 500, which includes a fitting feeding mechanism, a fitting coating mechanism (not shown) and a fitting drying mechanism (not shown). The fitting feeding mechanism is used to feed the fittings; the fitting coating mechanism is located on one side of the fitting feeding mechanism and is used to coat the inner surface of the fitting; the fitting drying mechanism is located on one side of the fitting feeding mechanism and is used to dry the coated fittings.

[0047] The hardware feeding mechanism includes a feeding platform 511, several feeding guide rails 512, a feeding drive 513, a feeding transmission assembly (not shown), and a feeding tray 514. Several feeding guide rails 512 are arranged in parallel at intervals on the feeding platform 511; the feeding tray 514 is slidingly connected to the feeding guide rails 512; the feeding drive 513 is arranged on the feeding platform 511; the feeding transmission assembly is arranged at the bottom of the feeding tray 514 and is connected to the power output end of the feeding drive 513, which is used to transmit the power of the feeding drive 513 to the feeding tray 514, and control the feeding tray 514 to move on the feeding guide rails 512. The loading tray 514 is provided with several hardware slots for placing hardware. The shape of the hardware slots matches the outer surface contour of the hardware to ensure that the hardware is securely placed. The loading tray 514 includes a first tray and a second tray, each used to place two types of hardware for insulator products. This allows the two types of hardware to be loaded simultaneously without having to disassemble or replace the loading tray 514, thereby improving production efficiency. A loading button 515 is provided at one end of the loading platform 511 for activating the hardware loading mechanism. A loading buffer 516 is provided at the other end of the loading platform 511 for limiting the maximum travel distance of the loading tray 514. By clicking the loading button 515, the loading tray 514 can be controlled to move along the loading guide rail 512 until the loading tray 514 abuts the loading buffer 516 and stops moving. The entire loading process is simple and convenient to operate.

[0048] The fitting coating mechanism is arranged on the loading platform 511 and is located on one side of the loading buffer 516, so as to facilitate the coating operation of the fittings that have completed the loading operation, shorten the circulation distance, and improve production efficiency. The fitting coating mechanism can be an infiltration tank, in which a fitting coating agent is placed. The conveying mechanism 20 is used to clamp the fittings and infiltrate them in the infiltration tank, so that the fitting coating agent adheres to the inner surface of the fittings to complete the coating operation of the fittings. The fitting coating agent can be a coupling agent or other reagent. The fitting coating mechanism also includes a second raw material conveying component (not shown) for continuously providing raw materials to the infiltration tank. The second raw material conveying component includes a raw material barrel, a pipeline and a peristaltic pump. The infiltration tank is connected to the raw material barrel by a pipeline. The peristaltic pump can drive the pipeline to absorb the raw material from the raw material barrel and continuously convey it to the infiltration tank, ensuring that the infiltration tank is always filled with sufficient fitting coating agent to ensure the coating effect. No additional raw materials need to be added during the production process, making the production rhythm more compact and more efficient.

[0049] The fitting drying mechanism is mounted on the loading platform 511 and is located to one side of the fitting coating mechanism. This facilitates drying of coated fittings, shortening the circulation distance and improving production efficiency. The fitting drying mechanism can be a blower or fan with its outlet facing upward from the fitting coating mechanism. Once the conveying mechanism 20 has removed the coated fittings from the fitting coating mechanism, the fitting drying mechanism can directly dry the fittings.

[0050] Combine Figure 5 and Figure 6 As shown, the stripping system 300 includes a support mechanism 310 and a stripping mechanism 320. The support mechanism 310 is used to fix the hardware and control its rotation. The stripping mechanism 320 is located above the support mechanism 310 and is used to strip the hardware. The stripping operation is to remove the oxide layer or stains on the crimping surface of the hardware to clean the hardware and avoid affecting the next processing step.

[0051] The supporting mechanism 310 is set on the workbench. The supporting mechanism 310 includes a first base 311, a rotating component 312 and a fixed component 313. The first base 311 is vertically installed on the workbench. The rotating component 312 is set on the first base 311 and is used to rotate the hardware. The rotation angle can be 360° or any angle; the fixed component 313 is connected to the rotating component 312 and is used to fix the hardware.

[0052] The rotating assembly 312 includes a rotating drive member 3121 and an active rotating member 3122. Both the rotating drive member 3121 and the active rotating member 3122 are disposed on the first base 311. The fixed assembly 313 is disposed on the active rotating member 3122. The rotating drive member 3121 drives the active rotating member 3122 to rotate, thereby causing the hardware on the fixed assembly 313 to rotate. The fixed assembly 313 includes a fixed platform 3131, a fixed seat 3132, and an auxiliary fixed member 3133. The fixed platform 3131 is horizontally fixed to the active rotating member 3122. The fixed seat 3132 and the auxiliary fixed member 3133 are disposed on the fixed platform 3131 and are used to cooperate with and fix the hardware. The fixed seat 3132 may specifically include an end fixed seat and a middle fixed seat arranged at intervals. The end fixed seat is used to abut one end of the hardware, and the middle fixed seat is used to support the middle of the hardware. The auxiliary fixing member 3133 can be a pressing member, which is arranged above the middle fixing seat and is used to press and fix the hardware to the fixing seat 3132. The hardware is fixed by the fixing seat 3132 and the auxiliary fixing member 3133, which is easy to operate and has a good fixing effect.

[0053] Furthermore, the rotating assembly 312 also includes a follower rotating member 3123. Correspondingly, the supporting mechanism 310 also includes a second base 314. The follower rotating member 3123 is movably connected to the second base 314, and the follower rotating member 3123 can move toward the first base 311 to abut the other end of the hardware. After fixing one end and the middle of the hardware using the fixed seat 3132 and the auxiliary fixing member 3133, the follower rotating member 3123 is controlled to abut the other end of the fixed hardware. The rotating driving member 3121 drives the active rotating member 3122 to rotate, driving the follower rotating member 3123 and the hardware to rotate, so that the rotation process of the hardware is more stable to facilitate the stripping operation.

[0054] The stripping mechanism 320 comprises a laser emitting assembly and a lens assembly, which is connected to the laser emitting assembly via a light transmission or light refraction conduit. The lens assembly can select different lenses and adjust the corresponding lens focal length according to the different metal oxide layers or stains to be stripped, so that the light emitted by the lens assembly can thoroughly strip the crimping surface of the hardware.

[0055] Furthermore, the peeling system 300 includes a moving device 330, on which the peeling mechanism 320 is mounted. The moving device 330 can drive the peeling mechanism 320 to move horizontally and vertically to adjust the distance between the lens assembly and the crimping surface of the hardware to ensure a good peeling effect. The moving device 330 can be a conventional moving mechanism and is not specifically limited herein.

[0056] Furthermore, the stripping system 300 can be provided with at least two sets of carrying mechanisms 310 and stripping mechanisms 320, which are respectively arranged at different workstations of the workbench. For example, when two sets of carrying mechanisms 310 and stripping mechanisms 320 are provided, the stripping system 300 can simultaneously strip the two hardware required for producing an insulator, thereby improving production efficiency; when four sets of carrying mechanisms 310 and stripping mechanisms 320 are provided, the stripping system 300 can simultaneously strip the four hardware required for producing two insulator products, thereby further improving production efficiency.

[0057] Furthermore, the stripping system 300 also includes a dust collection device 340, which includes a connected exhaust fan (not shown) and an exhaust duct 341. The exhaust duct 341 is arranged on one side of the supporting mechanism 310. The exhaust duct 341 is provided with at least one branch pipe 3411. The exhaust port of the branch pipe 3411 faces the hardware on the supporting mechanism 310, which can quickly collect the dust generated during the stripping. For example, if the stripping system 300 is provided with multiple workstations, a branch pipe 3411 is provided at each workstation to ensure the dust removal effect. In addition, in order to prevent the dust generated by the hardware during stripping from being inhaled by the staff, the stripping system 300 can be set in a closed space such as an equipment cabinet or a sealed cabinet. At the same time, in order to facilitate the staff to observe the stripping of the hardware, at least one side of the closed space is transparent, for example, the equipment cabinet is sealed by a glass door.

[0058] Combine Figure 7-10 As shown, in the crimping system 100, a mandrel supporting device 140 and at least one hardware supporting device 150 are provided on the supporting platform 120. The mandrel supporting device 140 is used to support the mandrel and control the movement of the mandrel, and the hardware supporting device 150 is used to support the hardware and control the movement of the hardware. The hardware supporting device 150 is arranged at the end position of the mandrel supported by the mandrel supporting device 140 to facilitate the connection between the hardware and the mandrel.

[0059] When the crimping system 100 is in operation, the mandrel support device 140 and the hardware support device 150 cooperate to move at least one of the mandrel and the hardware so that the hardware is placed on the end of the mandrel. For example, after the mandrel and the hardware are placed separately, the crimping system 100 can control the mandrel support device 140 to push the mandrel toward the hardware; or control the hardware support device to push the hardware toward the mandrel; or simultaneously control the mandrel support device and the hardware support device to move toward each other until the hardware is placed on the end of the mandrel. A preset placement position can be set in the crimping system 100, and the mandrel support device 140 and the hardware support device 150 cooperate to move at this preset placement position to place the hardware on the end of the mandrel.

[0060] One hardware support device 150 can be provided, located on one side of the mandrel support device 140, so that one hardware can be sleeved and crimped for the first time before another hardware can be sleeved and crimped for the second time; or, two hardware support devices 150 can be provided, located on both sides of the mandrel support device 140, so that the first sleeved and crimped operation and the second sleeved and crimped operation can be completed in sequence, making the production cycle more compact and the efficiency higher.

[0061] The support platform 120 includes a first support plate 121, a rotating mechanism 122, and a lifting mechanism 123. The core rod support device 140 and the hardware support device 150 are arranged on the first support plate 121; the rotating mechanism 122 is arranged below the first support plate 121, and is used to drive the first support plate 121 to rotate, and then the direction of the core rod and the hardware can be adjusted according to the operation requirements; the lifting mechanism 123 is arranged below the first support plate 121, and is used to adjust the height of the first support plate 121, and then the height of the core rod and the hardware can be controlled.

[0062] The rotating mechanism 122 includes a rotating base 1221 and a rotating power assembly 1222 . The rotating base 1221 is fixedly connected to the first support plate 121 . The rotating power assembly 1222 is connected to the rotating base 1221 via a speed regulator to drive the rotating base 1221 to rotate.

[0063] Furthermore, a zero position detection assembly can be provided on the first support plate 121 to detect whether the working position of the first support plate 121 is accurate. When the first support plate 121 is in the working position, the mandrel, the hardware, and the position where the two are crimped at the crimping machine 110 are located in the same straight line, making the movement path of the mandrel and the hardware for sleeve connection and crimping simpler and faster, thereby improving production efficiency. If the zero position detection assembly detects that the first support plate 121 is not accurately in the working position, the first support plate 121 can be controlled to rotate to the working position through the rotation mechanism 122. The zero position detection assembly can be a detection device or circuit such as a laser sensor.

[0064] The lifting mechanism 123 includes a base plate 1231, a guide assembly 1232, a first lifting plate 1233, a second lifting plate 1234 and a lifting power assembly 1235. The guide assembly 1232 is arranged on the base plate 1231 in the vertical direction; the first lifting plate 1233 is located below the first support plate 121, and the first lifting plate 1233 is slidingly connected to the guide assembly 1232; the second lifting plate 1234 is fixed below the first lifting plate 1233 through a lifting guide column 1236; the lifting power assembly 1235 is fixed below the second lifting plate 1234, and is used to drive the second lifting plate 1234 to drive the first lifting plate 1233 to move on the guide assembly 1232, thereby controlling the height of the core rod and hardware on the first support plate 121.

[0065] In one embodiment, the lifting mechanism 123 further includes a plurality of limiters 1237 disposed on the upper side of the guide assembly 1232 and above the first lifting plate 1233. The limiters 1237 are configured to abut the first lifting plate 1233 to limit the maximum travel height of the first lifting plate 1233. On the one hand, the limiters 1237 can constrain the first lifting plate 1233 to a target crimping height, facilitating subsequent crimping operations by the crimping system 100 at that height without requiring secondary height adjustments, thereby improving production efficiency. On the other hand, the limiters prevent the first lifting plate 1233 from moving excessively and potentially damaging other components of the equipment, thereby extending the service life of the crimping system 100.

[0066] The limiting member 1237 can be a limiting plate, and a limiting plate is fixedly provided on the top of the guide assembly 1232 in the horizontal direction. The two limiting plates are arranged relative to each other and close to each other. The ends of the two limiting plates close to each other and the projections of the two ends of the first lifting plate 1233 on the horizontal plane have a partially overlapping area, and this area is defined as a limiting area. Furthermore, in order to facilitate the adjustment of the maximum moving height of the first lifting plate 1233, a screw hole can be opened in the limiting area on the limiting plate, and a limiting nut is provided in the screw hole. By adjusting the height of the limiting nut, the maximum moving height of the first lifting plate 1233 can be easily adjusted, which facilitates the rapid limitation of core rods and hardware of different specifications to the target crimping height for crimping operations, while expanding the application range of the crimping system 100 and making the production cycle more compact and more efficient.

[0067] In one embodiment, the lifting mechanism 123 further includes a plurality of auxiliary supports 1238 rotatably disposed on top of the guide assembly 1232 and abutting the first support plate 121, for auxiliary support of the first support plate 121. The auxiliary supports 1238 may be roller structures. On the one hand, the provision of the auxiliary supports 1238 ensures a more stable and reliable placement of the mandrel and fittings on the first support plate 121, preventing unstable placement from affecting the sleeve and crimping operations and thus affecting product quality. On the other hand, when the first support plate 121 rotates, the auxiliary supports 1238 rotate with it, reducing friction between the two, slowing wear on the equipment, and extending its service life.

[0068] The mandrel supporting device 140 includes a mandrel supporting mechanism 141 and a mandrel moving mechanism 142 . The mandrel supporting mechanism 141 is used to support the mandrel. The mandrel moving mechanism 142 is disposed at the bottom of the mandrel supporting mechanism 141 and is used to control the movement of the mandrel.

[0069] In one embodiment, the mandrel support mechanism 141 includes a second support plate 1411, a plurality of mandrel support seats 1412, and a mandrel detection assembly 1413. The second support plate 1411 is disposed on the mandrel moving mechanism 142; the plurality of mandrel support seats 1412 are spaced apart on the second support plate 1411 to cooperate with supporting mandrels; and the mandrel detection assembly 1413 is disposed on the second support plate 1411 to detect whether a mandrel is present on the mandrel support seats 1412. The mandrel detection assembly 1413 may be a detection device or circuit such as a laser sensor or a weight sensor.

[0070] The mandrel support seat 1412 can be configured as a V-shaped plate, vertically disposed on the second support plate 1411, with multiple V-shaped plates spaced correspondingly along the axial direction of the mandrel for accommodating the mandrel. Furthermore, a fixing member can be provided on the mandrel support seat 1412 to secure the mandrel. For example, the fixing member can also be configured as an inverted V-shaped plate or a hold-down member, and the mandrel support seat 1412 and the fixing member cooperate to clamp and secure the mandrel.

[0071] The mandrel moving mechanism 142 includes a first guide rail 1421, a first power assembly 1422 and a first transmission assembly (not shown). The first guide rail 1421 is set along a first direction. The first direction is the direction from the socketing position of the mandrel and the hardware to the crimping position of the hardware in the crimping machine 110, so that the mandrel can be moved to the crimping machine 110 for crimping through the mandrel moving mechanism 142 after the socketing is completed; the specific structure and connection method of the mandrel moving mechanism 142 are similar to those of the mandrel moving assembly 421 and will not be repeated here.

[0072] The hardware support device 150 includes a hardware support mechanism 151 and a hardware moving mechanism 152 . The hardware support mechanism 151 is used to support the hardware; the hardware moving mechanism 152 is provided at the bottom of the hardware support mechanism 151 and is used to control the movement of the hardware.

[0073] The hardware support mechanism 151 includes a third support plate 1511, a hardware support base 1512, and a hardware detection assembly 1513. The third support plate 1511 is mounted on the hardware moving mechanism 152. The hardware support base 1512 is mounted on the third support plate 1511 and is used to support the hardware. The hardware detection assembly 1513 is mounted on the third support plate 1511 or the hardware support base 1512 and is used to detect whether a hardware is present on the hardware support base 1512. The hardware detection assembly 1513 can be a detection device or circuit such as a laser sensor or a weight sensor.

[0074] In order to facilitate the stable placement of the hardware, a receiving cavity matching the shape of the hardware can be provided on the hardware support seat 1512, or a clamping piece can be provided in the hardware support device 150, and the clamping piece is a rotatable pressing mechanism to further clamp and fix the hardware.

[0075] In one embodiment, in order to facilitate the movement of the sleeved core rod to the crimping machine 110 for crimping, the hardware support mechanism 151 needs to be moved to a range of motion that allows the core rod to exit, so a hardware moving mechanism 152 is provided. For example, the hardware support mechanism 151 can be controlled to move downward and exit, and the hardware moving mechanism 152 includes a second guide rail 1521 and a second power assembly 1522. The second guide rail 1521 is arranged on the first support plate 121 in the vertical direction, and the second guide rail 1521 is slidably connected to the hardware support mechanism 151; the second power assembly 1522 is arranged on the first support plate 121 and is located on one side of the second guide rail 1521. The power output end of the second power assembly 1522 is connected to the hardware support mechanism 151, and is used to control the hardware support mechanism 151 to move on the second guide rail 1521; correspondingly, the hardware support mechanism 151 and the mandrel support mechanism 141 can be pre-set to be located in the first direction, so that when the hardware and the mandrel are placed respectively, the two are directly coaxially arranged, so that the zero position detection assembly is used to detect whether the first support plate 121 is aligned with the crimping machine 110 to determine whether the first support plate 121 is accurately located in the working position. Alternatively, the hardware support mechanism 151 can also be controlled to move and exit along the second direction, where the second direction refers to the direction perpendicular to the first direction in the horizontal plane. The hardware moving mechanism 152 can still adopt the aforementioned structure, as long as the setting direction of the second guide rail 1521 is adjusted and the components are connected accordingly. No further details will be given.

[0076] Positioning mechanism 130 includes a positioning assembly 131 and a moving assembly 132. Positioning assembly 131 is configured to flexibly abut the hardware to be socketed, while moving assembly 132 controls the movement of positioning assembly 131. Positioning mechanism 130 simulates the twisting motion of manual socketing by flexing positioning assembly 131 against the hardware to be socketed. Simultaneously, mandrel moving mechanism 142 drives the mandrel. This coordinated twisting of the hardware and movement of the mandrel allows the mandrel to be socketed into the elongated inner cavity of the hardware, ensuring a high-quality socketing connection.

[0077] In one embodiment, the positioning assembly 131 includes a positioning base 1311, a first positioning plate 1312, a second positioning plate 1313 and a positioning roller 1314. The positioning base 1311 is a step-type block structure, including a first cavity 13111 and a second cavity 13112 arranged in sequence from top to bottom. The first cavity 13111 is used to install the first positioning plate 1312, the second positioning plate 1313 and the positioning roller 1314, and the second cavity 13112 is used to accommodate part of the hardware support seat 1512 so that the positioning assembly 131 can fully abut the hardware; the first positioning plate 1312 is arranged in the vertical direction. On the positioning base 1311, the first positioning plate 1312 is arranged along the second direction to facilitate abutting the end of the hardware to be sleeved; the second positioning plate 1313 is connected to the bottom end of the first positioning plate 1312, and the upper plate surface of the second positioning plate 1313 is inclined downward in the direction away from the first positioning plate 1312; the positioning roller 1314 is a rotatable roller structure, which is arranged on the positioning base 1311 in the vertical direction and the positioning roller 1314 is located on one side of the first positioning plate 1312. The positioning roller 1314 cooperates with the first positioning plate 1312 and the second positioning plate 1313 to movably abut the hardware to be sleeved.

[0078] In one embodiment, in order to facilitate the movement of the sleeved core rod to the crimping machine 110 for crimping, the positioning mechanism 130 needs to be moved to the range of motion for exiting the core rod, so a moving assembly 132 is provided. For example, the positioning assembly 131 can be controlled to move and exit along the second direction. The moving assembly 132 includes a mounting plate 1321, a third guide rail 1322 and a third power assembly 1323. The mounting plate 1321 is an L-shaped plate, which is arranged in the vertical direction. The cavity of the L-shaped plate partially overlaps with the second cavity 13112, which can allow the core rod to pass through and move to the crimping machine 110 for crimping. The mounting plate 1321 can be arranged on the side of the crimping machine 110 close to the support platform 120, so that the layout of the crimping system 100 is more compact and saves floor space. Alternatively, the mounting plate 1321 can be directly provided. The third guide rail 1322 is disposed on the mounting plate 1321 along the second direction, and the positioning assembly 131 is slidably connected to the third guide rail 1322. That is, the side of the positioning base 1311 near the crimping machine 110 is slidably connected to the third guide rail 1322. The third power assembly 1323 is disposed on the mounting plate 1321 and is located on one side of the third guide rail 1322. The power output end of the third power assembly 1323 is connected to the positioning assembly 131 for controlling the movement of the positioning assembly 131 on the third guide rail 1322. Alternatively, the positioning assembly 131 can be controlled to move out in the vertical direction. The moving assembly 132 can still adopt the aforementioned structure. It is only necessary to adjust the setting direction of the third guide rail 1322 and connect the various components accordingly. No further details will be given.

[0079] During socketing, first place the mandrel on the mandrel support seat 1412, place the hardware in the accommodating cavity of the hardware support seat 1512, then control the moving assembly 132 to drive the positioning assembly 131 to move along the second direction to the first direction, at this time the hardware support seat 1512 is partially accommodated in the second cavity 13112, the inclined upper plate surface of the second positioning plate 1313 abuts the end of the hardware, and then control the mandrel moving mechanism 142 to move along the first direction to push the mandrel toward the hardware, and under the resistance of the accommodating cavity of the hardware support seat 1512, the end of the mandrel is initially socketed into the hardware. The mandrel moving mechanism 142 continues to move the mandrel, and the hardware will move toward the positioning mechanism 130 under the action of the thrust, that is, push the hardware along the inclined upper plate surface of the second positioning plate 1313 to abut against the first positioning plate 1312 and the positioning roller 1314. Since this abutment method has a certain degree of mobility, the hardware will twist in the first cavity 13111. Under the continuous push of the mandrel moving mechanism 142, it will continue to twist so that the mandrel continues to move into the cavity of the hardware until the hardware is completely sleeved on the end of the mandrel, completing the sleeve operation. After the sleeve is completed, the control moving component 132 drives the positioning component 131 to exit in the second direction, reserving space for the subsequent movement of the mandrel with the hardware sleeved to the crimping machine 110 for crimping.

[0080] Furthermore, in order to protect the positioning mechanism 130, a limiting assembly 133 can be provided in the positioning mechanism 130, and the limiting assembly 133 includes an abutment plate 1331 and a buffer 1332. The abutment plate 1331 is an L-shaped plate, and the abutment plate 1331 is fixedly connected to the positioning assembly 131, that is, the long side end of the abutment plate 1331 is fixedly connected to the plate surface of the positioning base 1311 close to the crimping machine 110, and the long side of the abutment plate 1331 extends toward the side close to the moving assembly 132, and the short side of the abutment plate 1331 is used to abut with the buffer 1332; the buffer 1332 is provided on the mounting plate 1321 and is located on the moving path of the short side of the abutment plate 1331, and the abutment plate 1331 abuts against the buffer 1332 to limit the maximum moving distance of the moving assembly 132. When the moving assembly 132 drives the positioning assembly 131 to move in the second direction, it also drives the abutment plate 1331 to move until the abutment plate 1331 abuts against the buffer 1332 and gradually stops moving. At this time, the positioning assembly 131 is at the target abutment position. The provision of the limit assembly 133 not only provides a buffering and shock-absorbing effect, extending the service life of the equipment, but also facilitates the rapid movement of the positioning assembly 131 to the target abutment position, improving production efficiency.

[0081] Furthermore, since the hardware structures at both ends of the insulator product are generally different, in order to ensure the matching of the positioning mechanism 130 and the hardware to ensure the movable abutment effect, the present application sets two positioning mechanisms 130 of different sizes, that is, the first positioning plate 1312, the second positioning plate 1313 and the positioning roller 1314 are of different sizes to match the hardware of different movable abutment structures. The two positioning mechanisms 130 are both arranged between the crimping machine 110 and the support platform 120, and the two positioning rollers 1314 are arranged relative to each other. It is understandable that the two positioning components 131 are close to each other, and the two moving components 132 are far away from each other, so that the two moving components 132 can drive their respective positioning components 131 to move and avoid mutual interference. It is understandable that the specific size and installation position of the two positioning mechanisms 130 can be adjusted according to the socket requirements, and no specific restrictions are made here.

[0082] In one embodiment, in order to ensure that the hardware is accurately socketed on the core rod before the crimping operation is carried out to avoid the generation of waste, the crimping system 100 also includes a detection mechanism 160 for detecting whether the socketing position of the hardware on the core rod is accurate. The detection mechanism 160 includes a detection base 161, a fourth power component 162, a guide column 163 (the marks in the figure are only for schematic reference), a reference part 164, a spring part 165 and a socket detection component 166. The detection base 161 is arranged on the other side of the crimping machine 110; the fourth power component 162 is arranged on the detection base 161, and the power output end of the fourth power component 162 faces the crimping machine 110 and is connected to the first baffle 167, and the first baffle 167 is provided with a first through hole; the guide column 163 passes through the first through hole and is connected to the first baffle 167 through a fastener 168. Component 162 drives the first baffle 167 to move and thus controls the guide column 163 to move along the first direction. The fastener 168 can be a connecting component such as a sleeve; the reference component 164 is fixedly connected to the end of the guide column 163 close to the crimping machine 110 through the second baffle 169, and is used to abut the hardware sleeved on the end of the core rod, that is, before or during the crimping process of the hardware sleeved on the end of the core rod, the reference component 164 abuts the hardware. The reference component 164 can be an elastomer, so that when abutting the hardware, it can avoid damaging the surface of the hardware and affecting the product quality; the spring component 165 is sleeved on the outer periphery of the guide column 163, and the two ends of the spring component 165 abut the fastener 168 and the second baffle 169 respectively; the sleeve detection component 166 is arranged on the detection base 161, and is used to detect whether the spring component 165 is deformed. On the one hand, before crimping, the detection mechanism 160 can detect whether the fitting is correctly positioned on the core rod, thereby avoiding direct crimping due to the fitting not being properly positioned and resulting in waste, waste of materials and labor; on the other hand, when the fitting is crimped, the detection mechanism 160 can abut the end of the fitting that is not connected to the core rod, thereby avoiding displacement of the fitting and causing the crimping position to shift, thereby affecting product quality.

[0083] When the detection mechanism 160 is running, the fourth power assembly 162 can be used to first drive the first baffle 167 to move, and drive the guide column 163 and the second baffle 169 connected thereto to move, so that the reference piece 164 on the second baffle 169 stays at the preset crimping position. When the socket position of the hardware on the core rod is accurate, the core rod support device 140 drives the core rod with the hardware socketed to move to the preset crimping position. The end of the core rod with the hardware socketed can abut the reference piece 164 to wait for the subsequent crimping machine 110 to accurately crimp the core rod and the hardware to ensure the crimping quality. When the socket position of the hardware on the core rod is inaccurate, the core rod support device 140 drives the core rod with the hardware socketed to move to the preset crimping position. When the screw thread is tightened, the core rod supporting device 140 drives the core rod with the hardware to move to the preset crimping position. Since the hardware is not properly fitted on the core rod, the end of the hardware away from the core rod will exceed the preset crimping position, thereby generating a certain thrust on the reference part 164, thereby pushing the second baffle 169 to compress the spring part 165 to move. The fitting detection component 166 detects the deformation of the spring part 165 and sends a warning signal. The crimping machine 110 does not perform the crimping operation, avoiding the crimping machine 110 directly performing the crimping operation at this position, which will cause the crimping position of the hardware on the core rod to be inaccurate, resulting in scrap, waste of materials and labor.

[0084] Combine Figure 11 As shown, the production line 10 for insulator products further includes a preheating system 600 for heating the insulator preforms at a preheating station, which is located between the crimping station and the injection station.

[0085] The preheating system 600 includes a preheating rack 610, a preheating conveyor assembly 620 and an oven 630. The preheating conveyor assembly 620 is set on the preheating rack 610 and is used to control the movement of the insulator preforms to be preheated into the oven 630 and control the movement of the preheated insulator preforms out of the oven 630. The oven 610 is set in the middle of the preheating conveyor assembly 620 and is used to heat the insulator preforms.

[0086] The preheating conveying assembly 620 includes two movable racks 621, which are arranged in parallel at intervals on the preheating rack 610 for cooperating in carrying the insulator preform and controlling the movement of the insulator preform. A transfer button is provided on the preheating conveying assembly 620 for controlling the movement of the movable rack 621. Several bearing positions are evenly spaced along the moving direction of the preheating conveying assembly 620, that is, a plurality of bearing seats 622 are correspondingly provided on the two movable racks 621, and every two corresponding bearing seats 622 on the two movable racks 621 form a bearing position, wherein several bearing positions are provided in the heating area of the oven 630, and a bearing position is provided on each side outside the heating area. The bearing position outside the heating area and closest to the crimping system 100 is defined as the loading bearing position, and the bearing position outside the heating area and farthest from the crimping system 100 is defined as the unloading bearing position. When the core rod and the hardware are crimped to form the insulator preform, the conveying mechanism 20 can be The insulator preform is transported to the loading load position and the transfer button is activated. The preheating conveying component 620 moves forward a preset distance along its moving direction so that the loading load position enters the first load position in the heating area. The next insulator preform is then transported to the loading load position and the transfer button is activated until all load positions in the heating area are filled with insulator preforms. When the insulator preform at the last load position in the heating area completes the heating operation, the transfer button is activated to move it forward to the unloading load position. The conveying mechanism 20 can then transport the insulator preform at this position to the injection system. The above operations are repeated in sequence, thereby realizing the assembly line operation of the insulator preform heating operation.

[0087] Furthermore, the preheating conveying assembly 620 also includes a preheating drive component for controlling at least one movable frame 621 to move in a direction perpendicular to its moving direction to adjust the distance between the two movable frames 621, and then adjust the distance between the corresponding supporting seats 622 to carry insulator preforms of more length specifications, thereby improving the versatility of the equipment.

[0088] Furthermore, the preheating conveyor assembly 620 is also equipped with a sensor for detecting whether an insulator preform is placed at the loading position. If no insulator preform is placed, a prompt is given to continue placing the insulator preform. Alternatively, a sensor is provided for detecting whether an insulator preform at the unloading position has been removed by the conveyor mechanism 20. If so, the preheating conveyor assembly 620 is controlled to advance one position to replenish the insulator preform. The distance and rhythm of movement of the preheating conveyor assembly 620 can be adjusted according to heating requirements and are not specifically limited here.

[0089] The oven 630 is a heating device with openings at both ends. These openings allow the preheating conveyor assembly 620 to move through the oven 630. Furthermore, lift doors can be provided at the openings at both ends of the oven 630 to close the openings when the insulator preforms within the oven 630 are being heated and the preheating conveyor assembly 620 does not need to move, thereby reducing heat loss and improving heating efficiency. The oven 630 can be implemented using existing technology and is not specifically limited herein.

[0090] Furthermore, preheating system 600 also includes a temperature detection assembly 640, mounted on preheating frame 610 at the unloading position. This assembly is used to detect whether the surface temperature of the heated insulator preform meets the requirements for subsequent injection molding, thereby ensuring injection quality. Temperature detection assembly 640 can be implemented using existing technology, as long as it can achieve the corresponding function, and is not specifically limited here.

[0091] The injection system includes an injection molding machine and a feeder rack. The injection molding machine is used to inject insulator preforms. The feeder rack is located at the injection molding machine's feed port and is used to place and move the insulator preforms. A conveyor mechanism 20 moves the heated insulator preforms onto the feeder rack. The feeder rack controls the movement of the insulator preforms into the injection mold within the injection molding machine and secures them in place. The injection molding machine then injects the insulator preforms, injecting high-temperature vulcanized silicone rubber molded sheds around the core rod of the insulator preform. This creates a sealed connection between the core rod, hardware, and sheds, resulting in the final insulator product. The injection molding system can be implemented using existing technologies and is not specifically limited here.

[0092] Combine Figure 1 As shown, the production line 10 of the present application includes two conveying mechanisms 20 (only one is shown in the figure), and the crimping system 100, the coating system 200, the stripping system 300, and the preheating system 600 can be arranged around one of the conveying mechanisms 20 to facilitate the conveying mechanism 20 to transport core rods, hardware, and insulator preforms between the stripping station, the coating station, the crimping station, and the preheating station. The conveying mechanism 20 is defined as the first conveying mechanism; the preheating system 600, the injection system and the other conveying mechanism 20 can be distributed in a triangular shape to facilitate the conveying mechanism 20 to transport insulator preforms and insulator products between the above-mentioned preheating station and the injection station. The conveying mechanism 20 is defined as the second conveying mechanism. The above arrangement can improve the operating efficiency.

[0093] Furthermore, the core rod coating device 200 and the crimping system 100 are both arranged along the first direction and are respectively located on both sides of the first conveying mechanism, so that after the first conveying mechanism grabs the core rod that has completed the coating operation from the core rod coating device 200, it can be directly placed on the crimping system 100 for standby without adjusting the direction of the core rod; the crimping system 100, the hardware coating device 500 and the stripping system 300 are arranged adjacent to each other in sequence, so that after the first conveying mechanism grabs the hardware from the loading tray 514 of the hardware coating device 500, it can be quickly transferred to the stripping system 300 for stripping operation, and the hardware that has completed stripping can be quickly transferred to the hardware coating mechanism of the hardware coating device 500 for coating and drying operation, and then quickly transfer the dried hardware to the crimping system 100 for standby use; the preheating system 600 can be adjacently arranged on the other side of the crimping system 100 away from the hardware coating device 500, so that the first conveying mechanism grabs the insulator preform from the crimping system 100 and quickly transfers it to the preheating system 600 for preheating operation; the injection system can be adjacently arranged on the other side of the preheating system 600 away from the crimping system 100, so that the second conveying mechanism can grab the preheated insulator preform from the preheating system 600 and quickly transfer it to the injection system for injection operation. Through the above arrangement, the moving distance of the conveying mechanism 20 at each workstation can be shortened, the transfer rhythm can be accelerated, and the production efficiency can be improved.

[0094] Furthermore, the hardware coating device 500 and the crimping system 100 are arranged at intervals in the first direction, and are arranged on both sides of the first conveying mechanism opposite to the core rod coating device 200 along the second direction. The stripping system 300 and the preheating system 600 are arranged on both sides of the first conveying mechanism opposite to each other along the second direction, and both are partially located between the hardware coating device 500, the crimping system 100 and the core rod coating device 200, so that the crimping system 100, the coating system 200, the stripping system 300, and the preheating system 600 can roughly surround a rectangular space, and the first conveying mechanism is located in the middle of the rectangular space, which can further speed up the transfer rhythm and improve production efficiency; at the same time, it also makes the layout of the production line 10 more compact and saves space.
