[0069] In an embodiment, in order to move the sleeved core rod to the crimping machine 110 for crimping, the positioning mechanism 130 needs to be moved out of the movement range of the core rod, so the moving assembly 132 is arranged. The moving assembly 132 comprises a mounting plate 1321, a third guide rail 1322 and a third power assembly 1323. The mounting plate 1321 is an L-shaped plate arranged in the vertical direction.

[0071] In an embodiment, to ensure that the metal fitting is accurately sleeved on the core rod before the crimping operation is performed, and to avoid generating waste products, the crimping system 100 further comprises a detection mechanism 160 for detecting whether the sleeving position of the metal fitting on the core rod is accurate. The detection mechanism 160 comprises a detection base 161, a fourth power assembly 162, a guide column 163 (only indicated in the figure), a reference element 164, a spring element 165, and a sleeving detection assembly 166. The detection base 161 is arranged on the other side of the crimping machine 110. The fourth power assembly 162 is arranged on the detection base 161. The power output end of the fourth power assembly 162 faces the crimping machine 110 and is connected with a first baffle 167. The first baffle 167 is provided with a first through hole. The guide column 163 passes through the first through hole and is connected with the first baffle 167 through a fastener 168. The fourth power assembly 162 drives the first baffle 167 to move and in turn controls the guide column 163 to move in a first direction. The fastener 168 can be a shaft sleeve or the like. The reference element 164 is fixedly connected with the guide column 163 at the end close to the crimping machine 110 through a second baffle 169. The reference element 164 is used to abut against the metal fitting sleeved on the end of the core rod. That is, before the metal fitting sleeved on the end of the core rod is crimped or during the crimping process, the reference element 164 abuts against the metal fitting. The reference element 164 can be an elastic body. In this way, when abutting against the metal fitting, the surface of the metal fitting can be prevented from being damaged, thereby affecting the product quality. The spring element 165 is sleeved on the outer periphery of the guide column 163. The two ends of the spring element 165 abut against the fastener 168 and the second baffle 169, respectively. The sleeving detection assembly 166 is arranged on the detection base 161 and is used to detect whether the spring element 165 is deformed. On the one hand, before crimping, the detection mechanism 160 can detect whether the sleeving position of the metal fitting on the core rod is accurate. In this way, the metal fitting can be prevented from being directly crimped without being sleeved in place, thereby generating waste products and wasting materials and labor. On the other hand, when the metal fitting is crimped, the detection mechanism 160 can abut against the end of the metal fitting not connected with the core rod. In this way, the metal fitting can be prevented from being displaced and causing the crimping position to deviate, thereby affecting the product quality.

[0072] In combination Figure 11 As shown in the figure, the production line 10 of the insulator product further comprises a preheating system 600 for heating the insulator preform at a preheating station. The preheating station is located between the crimping station and the injection station.

The preheating conveying assembly 620 is arranged on the preheating rack 610 and is used to control the movement of the insulator preform to be preheated into the oven 630 and the movement of the insulator preform after preheating out of the oven 630. The oven 610 is arranged at the middle part of the preheating conveying assembly 620 and is used to heat the insulator preform.

[0074] The preheating conveying assembly 620 comprises two moving frames 621 which are arranged in parallel and spaced apart on the preheating frame 610, and are used to carry the insulator preform and control the movement of the insulator preform. The preheating conveying assembly 620 is provided with a conveying button for controlling the movement of the moving frames 621. The preheating conveying assembly 620 is uniformly and spaced apart provided with a plurality of carrying positions along the moving direction of the preheating conveying assembly 620, that is, a plurality of carrying seats 622 are correspondingly provided on the two moving frames 621, and each two corresponding carrying seats 622 on the two moving frames 621 form a carrying position. A plurality of carrying positions are provided in the heating area of the oven 630, and one carrying position is provided on each side outside the heating area. The carrying position located outside the heating area and closest to the pressure connection system 100 is defined as the feeding carrying position, and the carrying position located outside the heating area and farthest from the pressure connection system 100 is defined as the discharging carrying position. After the core rod and the fitting complete the pressure connection to form the insulator preform, the conveying mechanism 20 can convey the insulator preform to the feeding carrying position, and start the conveying button. The preheating conveying assembly 620 moves forward by a preset distance along its moving direction, so that the feeding carrying position enters the first carrying position in the heating area. Then the next insulator preform is continuously conveyed to the feeding carrying position and the conveying button is started. The above operation is repeated until all the carrying positions in the heating area are placed with the insulator preform. When the insulator preform in the last carrying position in the heating area completes the heating operation, the conveying button is started to move to the discharging carrying position. The conveying mechanism 20 can convey the insulator preform at this position to the injection system, and the above operation is repeated in sequence, so as to realize the flow line operation of the insulator preform heating operation.

[0075] The oven 630 is a heating device with two open ends. The two open ends can allow the preheating conveying assembly 620 to move through the oven 630, and the openings at the two ends of the oven 630 can be provided with lifting doors for closing the openings at the two ends of the oven 630 when the insulator preform in the oven 630 is heated and the preheating conveying assembly 620 does not need to move, so as to reduce heat loss and improve heating efficiency. The oven 630 can be realized by using the existing technology, and specific limitations are not made here.

[0076] Further, the preheating system 600 further comprises a temperature detection assembly 640 arranged on the preheating frame 610 and located at the discharging carrying position, which is used to detect whether the surface temperature of the insulator preform after the heating operation meets the requirements of the subsequent injection operation, so as to ensure the injection quality. The temperature detection assembly 640 can be realized by using the existing technology, as long as the corresponding function can be realized, and specific limitations are not made here.

[0077] The injection system comprises an injection machine and a feeding rack. The injection machine is used for injection operation on the insulator preform. The feeding rack is located at the feeding port of the injection machine and is used for placing and moving the insulator preform. The conveying mechanism 20 can move the insulator preform after the heating operation to the feeding rack. The feeding rack controls the movement of the insulator preform to the injection mold in the injection machine and locks and fixes the insulator preform. The injection machine performs injection operation on the insulator preform, that is, high-temperature vulcanized silicone rubber is injected around the core rod of the insulator preform to form an umbrella skirt, and the core rod, the fitting, and the umbrella skirt are sealed and connected, so as to obtain the insulator product. The injection system can be realized by using the prior art, and is not specifically limited here.
