[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] The hardware loading mechanism includes a loading platform 511, several loading guide rails 512, a loading drive 513, a loading transmission assembly (not shown), and a loading tray 514. Several loading guide rails 512 are arranged in parallel at intervals on the loading platform 511; the loading tray 514 is slidably connected to the loading guide rails 512; the loading drive 513 is set on the loading platform 511; the loading transmission assembly is set at the bottom of the loading tray 514 and connected to the power output end of the loading drive 513, which is used to transmit the power of the loading drive 513 to the loading tray 514 and control the movement of the loading tray 514 on the loading 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 firmly placed. A loading button 515 is provided at one end of the loading platform 511 for starting the hardware loading mechanism; a loading buffer 516 is provided at the other end of the loading platform 511 for limiting the maximum moving 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 against the loading buffer 516 and stops moving. The entire loading process is simple and convenient to operate.

[0052] 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), whose structure and function are similar to those of the first raw material conveying component 4122 and will not be repeated here.

[0053] The hardware drying mechanism is arranged on the loading platform 511 and is located on one side of the hardware coating mechanism, so as to facilitate drying the hardware after coating, shorten the circulation distance and improve production efficiency. The hardware drying mechanism can be a blower or fan.

[0054] 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.

[0055] 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.

[0056] 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.
