Description

Technical Field

[0001] This utility model belongs to the technical field of insulator dipping equipment, specifically relating to a suspension insulator dipping device. Background Technology

[0002] Insulator dip coating is an advanced surface treatment process, mainly used to coat the surface of insulators with anti-flashover coatings to improve their insulation performance and pollution resistance.

[0003] In the existing insulator dip coating system, the insulator with a steel cap ball socket installed at the top is placed on the workpiece conveying station of the conveyor line. The workpiece conveying station moves the insulator along the conveyor line to the bottom of the dip coating machine head. Then, the dip coating machine head clamps the steel cap ball socket at the top of the insulator. Next, the workpiece conveying station reverses and resets. The dip coating tank moves on the conveyor line to the bottom of the dip coating machine head where the insulator has been attached. The dip coating machine head and the dip coating tank work together to coat the surface of the insulator with anti-flashover coating, completing the surface treatment process of the insulator.

[0004] Furthermore, existing dip coating systems are all devices for surface treatment of individual insulators, such as the prior art with publication number WO2016127508A1. In practice, their production efficiency is low and can no longer meet the high-efficiency requirements faced by people in the context of rapid social development. Utility Model Content

At least two L-shaped mounting plates distributed along the length direction are detachably connected to the upper mounting rod, and each second ranging laser sensor is mounted on one L-shaped mounting plate.

[0018] As a preferred technical solution of this utility model, a material trough installation platform is fixed on the upper part of the material trough moving assembly, and a material trough lifting cylinder is installed in the middle of the material trough installation platform. The telescopic rod of the material trough lifting cylinder is connected to the bottom of the material trough. At least two second vertical rods are provided around the bottom of the material trough, and each second vertical rod slides vertically on the material trough installation platform through a third sliding bearing.

[0019] As a preferred technical solution of this utility model, the dip coating machine head assembly includes a machine head mounting beam and vertical support columns supporting both ends of the machine head mounting beam. The two vertical support columns are respectively located on both sides of the ground rail. At least two electric clamping mechanisms arranged along its length are installed on the machine head mounting beam. The electric clamping mechanism includes a ball head bolt for hooking a steel cap ball socket and a rotating shaft for driving the ball head bolt to rotate. The ball head bolt is located below the machine head mounting beam, and the rotating shaft is rotatably connected to the machine head mounting beam. The lower end of the rotating shaft is connected to the ball head bolt. A clamping head located below the machine head mounting beam is sleeved on the rotating shaft. Two clamping cylinders are installed on the machine head mounting beam. The two clamping cylinders are respectively located at... On both sides of the rotating shaft, connecting plates are fixed to the telescopic rods of the two clamping cylinders. The outer wall of the clamping head is rotatably connected to the middle of the connecting plate through ball bearings, so as to drive the clamping head to move downward through the clamping cylinders and clamp the steel cap ball socket with the ball head bolt.

[0020] As a preferred technical solution of this utility model, both ends of the machine head mounting beam are fixed with a flipping shaft. The two flipping shafts are rotatably connected to the upper ends of two vertical support columns through bearing seats. A second drive motor for driving the flipping shaft to rotate is installed on one vertical support column. A vertical plate is fixed on the other vertical support column. The vertical plate is located on the side of the bearing seat away from the machine head mounting beam. Multiple U-shaped photoelectric sensors arranged in a ring on the vertical plane are installed on the side of the vertical plate close to the bearing seat.

[0021] As a preferred technical solution of this utility model, the suspension insulator dipping device further includes a controller and a sealed working chamber.

The controller is electrically connected to the workpiece loading and unloading assembly, workpiece height measuring assembly, dipping head assembly, material tank moving assembly, temperature control mechanism, and humidity control mechanism.

[0022] Beneficial Effects: Before production, this invention first controls the workpiece loading and unloading assembly to move along the ground rail to below the dip coating machine head assembly. The height of the electric clamping mechanism is measured using a first ranging laser sensor. Then, the workpiece loading and unloading assembly is reset, allowing at least two insulators with steel cap ball sockets at their upper ends to be placed on the respective workpiece chucks. This ensures the chucks clamp the insulators tightly, guaranteeing their stability during movement. Next, the insulator coating process can begin. During coating, the workpiece loading and unloading assembly moves the insulators towards the dip coating machine head assembly. When passing the workpiece height measuring assembly, the second ranging laser sensor can detect... The height of each steel cap socket is measured to determine the height difference between the steel cap socket and the electric clamping mechanism. Before the workpiece loading and unloading assembly moves to below the dip coating head assembly, the chuck lifting mechanism drives the workpiece chuck to rise, raising the steel cap socket to the specified height. Then, the workpiece loading and unloading assembly continues to move, allowing the steel cap socket to be directly hooked onto the electric clamping mechanism. The workpiece chuck is also released from its restraint on the insulator, and the workpiece loading and unloading assembly is reset. Next, the material tank moving assembly moves to the dip coating head assembly, placing the insulator in the coating inside. The electric clamping mechanism controls the rotation within the coating to achieve uniform coating treatment on the surface of the insulator.

[0023] This invention facilitates the automatic connection of multiple insulators through the cooperation of a first and a second ranging laser sensor. It also facilitates the alternating connection of insulators on different dip coating head assemblies and the alternating coating of different dip coating head assemblies within the material tank moving assembly through at least two dip coating head assemblies. This enables automated production and significantly improves production efficiency. Attached Figure Description

Detailed Implementation

[0035] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0036] Example:

[0037] like Figures 1-10 As shown, this embodiment provides a suspension insulator dip coating device, including a ground rail 1 and workpiece loading and unloading assembly 2, workpiece height measuring assembly 3, dip coating head assembly 4, and material tank moving assembly 5 arranged sequentially along the length of the ground rail 1. The workpiece loading and unloading assembly 2 and the material tank moving assembly 5 are located at opposite ends of the ground rail 1 to avoid mutual interference. Both the workpiece loading and unloading assembly 2 and the material tank moving assembly 5 are electrically slidable on the ground rail 1 for easy movement. At least two dip coating head assemblies 4 arranged sequentially along the length of the ground rail 1 are provided between the workpiece height measuring assembly 3 and the material tank moving assembly 5. This facilitates alternating coating processes in practice, improving processing efficiency. Figure 1 The example shown uses four workpiece chucks to facilitate surface treatment of multiple insulators at once. To ensure the stability of the insulators as they move on the ground rail 1, the workpiece loading and unloading assembly 2 is equipped with at least two workpiece chucks arranged along the width of the ground rail 1. These chucks hold the insulators with steel cap ball sockets installed at the top, ensuring the stability of the insulators as they move on the ground rail 1 with the workpiece loading and unloading assembly 2. At the same time, the insulators are arranged sequentially to facilitate the simultaneous processing of multiple insulators.

[0038] Similarly, at least two electric clamping mechanisms are installed on the dip coating head assembly 4, arranged along the width direction of the ground rail 1, to clamp the steel cap ball socket through the electric clamping mechanism and control the insulator connected to the steel cap ball socket to rotate in the material trough 501 at the upper end of the material trough moving assembly 5, so as to ensure that all insulators can be hooked on the dip coating head assembly 4 when they move to a position of the dip coating head assembly 4, and then be surface coated in the material trough 501 in the subsequent process.

[0039] To ensure that the insulators on the workpiece loading and unloading assembly 2 can be attached to the dip coating head assembly 4, a chuck lifting mechanism is connected to the lower end of each workpiece chuck. When the workpiece loading and unloading assembly 2 moves all the insulators to below the dip coating head assembly 4, the chuck lifting mechanism lifts the insulators on the workpiece chucks toward the electric clamping mechanism, so that the steel cap ball socket can be attached to the electric clamping mechanism at a suitable height. This ensures smooth attachment and also leaves a certain space between the steel cap ball socket and the electric clamping mechanism, so as to facilitate surface coating treatment of insulators of different sizes.

[0040] To achieve automated production, a first ranging laser sensor 201 is installed on one side of each workpiece chuck, such as the side of the workpiece chuck closer to the dip coating head assembly 4 or the side of the workpiece chuck further away from the dip coating head assembly 4. This ensures that when the workpiece loading and unloading assembly 2 moves on the ground rail 1, the insulator at the upper end of the workpiece chuck is in a straight line with the first ranging laser sensor 201. This is used to detect the height of each electric clamping mechanism before production. Then, when the insulator is attached to the electric clamping mechanism, the lifting mechanism of the chuck can be used to precisely control the rising height of the steel cap ball socket, thereby precisely controlling the attachment of the steel cap ball socket to the electric clamping mechanism.

[0041] To further ensure that the steel cap ball socket can be accurately attached to the electric clamping mechanism, at least two second ranging laser sensors 301 arranged along the width direction of the ground rail 1 are provided on the workpiece height measuring component 3. When the workpiece loading and unloading component 2 passes the workpiece height measuring component 3, the second ranging laser sensors 301 measure the height of each steel cap ball socket plane. Then, by using the measurement data of the first ranging laser sensor 201 and the measurement data of the second ranging laser sensor 301, the height difference between the steel cap ball socket and the electric clamping mechanism can be accurately calculated. In this way, the lifting height of the steel cap ball socket can be precisely controlled by the chuck lifting mechanism to achieve accurate attachment of the steel cap ball socket to the electric clamping mechanism.

[0042] Before production, this invention first controls the workpiece loading and unloading assembly 2 to move along the ground rail 1 to below the dip coating head assembly 4. The first distance-measuring laser sensor 201 measures the height of the electric clamping mechanism. Then, the workpiece loading and unloading assembly 2 is reset, allowing at least two insulators with steel cap ball sockets at their upper ends to be placed on the respective workpiece chucks. This ensures the workpiece chucks clamp the insulators, guaranteeing their stability during movement. Next, the insulator coating process can begin. During coating, the workpiece loading and unloading assembly 2 moves the insulators towards the dip coating head assembly 4. When passing the workpiece height measuring assembly 3, the second distance-measuring laser sensor 301 can... The height of each steel cap socket is detected to determine the height difference between the steel cap socket and the electric clamping mechanism. Before the workpiece loading and unloading assembly 2 moves to below the dip coating head assembly 4, the chuck lifting mechanism drives the workpiece chuck to rise, raising the steel cap socket to the specified height. Then, the workpiece loading and unloading assembly 2 continues to move, allowing the steel cap socket to be directly hooked onto the electric clamping mechanism. The workpiece chuck is also released from its restraint on the insulator, and the workpiece loading and unloading assembly 2 is controlled to reset. Next, the material tank moving assembly 5 moves to the dip coating head assembly 4, placing the insulator in the coating inside. The electric clamping mechanism controls the rotation in the coating to achieve uniform coating treatment on the surface of the insulator.

[0043] This invention facilitates the automatic connection of multiple insulators through the cooperation of the first ranging laser sensor 201 and the second ranging laser sensor 301. With at least two dip coating head assemblies 4, it facilitates the alternating connection of insulators on different dip coating head assemblies 4 and the alternating coating of different dip coating head assemblies 4 in the material tank moving assembly 5. This facilitates automated production and can significantly improve production efficiency.

[0044] As a preferred embodiment of this invention, it should be further explained that the ground rail 1 includes two parallel rail sections 101 connected by a connecting rod to ensure stability. Each of the two rail sections 101 is fixed with parallel longitudinal slide rails 102 and racks 103, both extending along the length of the rail section 101. The lower end of the workpiece loading / unloading assembly 2 is fixed with first sliders 202 slidably connected to the two longitudinal slide rails 102 and first gears 204 driven by a first motor 203. The two first gears 204 mesh with the two racks 103 respectively. In practice, by controlling the rotation of the first gears 204 through the first motor 203, the first gears 204 can move along the extension direction of each rack 103, thereby driving... The entire workpiece loading and unloading assembly 2 moves on the ground rail 1. The cooperation between the first slider 202 and the longitudinal slide rail 102 makes the movement of the workpiece loading and unloading assembly 2 more stable. The lower end of the material trough moving assembly 5 is fixed with a second slider 502 that is slidably connected to the two longitudinal slide rails 102 and a second gear 504 driven by a second motor 503. The two second gears 504 mesh with the two racks 103 respectively. Similarly, the rotation of the second gears 504 driven by the second motor 503 can make the second gears 504 move along the extension direction of the racks 103, thereby driving the entire material trough moving assembly 5 to move on the ground rail 1. The cooperation between the second slider 502 and the longitudinal slide rail 102 makes the movement of the material trough moving assembly 5 more stable.

[0045] As a preferred embodiment of this example, it should be further explained that the upper part of the workpiece loading and unloading assembly 2 is provided with a chuck mounting platform 205. At least two mounting plates 206 arranged along the width direction of the ground rail 1 are mounted on the upper end of the chuck mounting platform 205. Each mounting plate 206 is equipped with a first ranging laser sensor 201 on the chuck mounting platform 205 near the dip coating head assembly 4. This allows the first ranging laser sensor 201 to detect the height of the electric clamping mechanism first when the workpiece loading and unloading assembly 2 moves, thereby reducing the sliding distance of the workpiece loading and unloading assembly 2 and saving resources. The upper end of each mounting plate 206 is provided with a transverse slide rail 207 extending along the width direction of the ground rail 1. A workpiece chuck is correspondingly provided above each mounting plate 206, and the lower end of the workpiece chuck is provided with a transverse slider 208 that slides on the transverse slide rail 207. This allows for adjustment by moving the transverse slider 208 on the transverse slide rail 207. The movement of the workpiece chuck in the width direction of the ground rail 1 enables precise positioning of the insulator, ensuring that the insulator and the corresponding electric clamping mechanism remain in a straight line, thus facilitating automated operation of the equipment. Each mounting plate 206 is equipped with a chuck lifting mechanism between itself and the chuck mounting platform 205. The chuck lifting mechanism includes a chuck lifting cylinder 209 mounted on the chuck mounting platform 205. The telescopic rod of the chuck lifting cylinder 209 is connected to the middle of the mounting plate 206, facilitating control of the insulator's lifting and lowering on the mounting plate 206 via the chuck lifting cylinder 209. The chuck lifting mechanism also includes at least two first vertical rods 210 mounted on the lower end of the mounting plate 206. Each first vertical rod 210 slides vertically on the chuck mounting platform 205 via a first sliding bearing 211. Therefore, when the mounting plate 206 is lifted or lowered, the first vertical rod 210 slides in cooperation with the chuck mounting platform 205, improving the stability of the mounting plate 206 during lifting and lowering.

[0046] As a preferred embodiment of this invention, it should be further explained that the workpiece chuck includes a base 212 and a bottom plate 213 arranged sequentially from bottom to top. The edge of the bottom plate 213 is connected to the base 212 through a support column 214 to ensure integrity. A steel foot fixing seat 215 for supporting the lower end of the steel foot of the insulator is provided in the middle of the bottom plate 213. The stability of the insulator is ensured by the support of the steel foot fixing seat 215. The lower part of the steel foot fixing seat 215 slides vertically on the bottom plate 213 through a second sliding bearing 216, ensuring that the steel foot fixing seat 215 can only be raised and lowered stably vertically, and also ensuring the stability of the insulator when the steel foot fixing seat 215 is raised and lowered. A return spring 217 is sleeved on the lower part of the steel foot fixing seat 215. The two ends of the return spring 217 abut against the second sliding bearing 216 and the middle part of the steel foot fixing seat 215, respectively, so that the steel foot The fixed base 215 can automatically reset after descent. It should be noted that the steel foot fixed base 215 can be a multi-segment structure with different diameters, or it can have a limit structure in the middle to abut against the return spring 217. The steel foot fixed base 215 is provided with at least two grippers 218 rotatably connected to the base plate 213 around its perimeter. The steel foot fixed base 215 is connected to all the grippers 218 through a hinge mechanism, so that when the steel foot fixed base 215 moves downward, the hinge mechanism drives the upper ends of all the grippers 218 to move towards the steel foot fixed base 215 and clamp the steel foot of the insulator. In practice, when the insulator is placed on the steel foot fixed base 215, it will press down on the steel foot fixed base 215. The downward movement of the steel foot fixed base 215 will drive the hinge mechanism to move. The movement of the hinge mechanism will drive the upper parts of the grippers 218 to move towards the insulator and clamp the insulator. It should be noted that when the insulator is attached to the electric clamping mechanism, the chuck lifting cylinder 209 retracts, causing the workpiece chuck to descend, and the steel foot fixing seat 215 moves upward relative to the base plate 213, thereby causing the upper end of the gripper 218 to move away from the insulator and automatically release the restraint on the insulator.

[0047] Preferably, the upper end of the steel foot fixing seat 215 is provided with a limiting groove, and the steel foot on the lower inner side of the insulator can be supported in the limiting groove, further improving the stability of the insulator.

[0048] As a preferred embodiment of this example, it should be further explained that at least two hinge seats 219 are fixed on the base plate 213 around the steel foot fixing seat 215. The gripper 218 includes an upper clamping rod and a lower connecting rod, which are integrally formed. The connection between the upper clamping rod and the lower connecting rod is rotatably connected to the hinge seat 219, allowing the upper and lower parts of the gripper 218 to swing around its middle part. The upper end of the upper clamping rod is inclined upwards towards the steel foot fixing seat 215, and in its natural state, space is reserved between all the grippers 218 for the steel foot to fall onto the steel foot fixing seat 215. The lower end of the lower connecting rod rotates with the hinge mechanism, thereby... When the insulator is supported on the steel foot fixing seat 215, gravity will cause the steel foot fixing seat 215 to move downward. The steel foot fixing seat 215 will drive the lower end of the lower connecting rod to move downward through the hinge mechanism, thereby causing the upper end of the upper clamping rod to move towards the steel foot and clamp the steel foot of the insulator. The hinge mechanism includes a positioning ring 220 and at least two hinge rods 221. The positioning ring 220 is fixedly connected to the middle of the steel foot fixing seat 215 and can move up and down with the steel foot fixing seat 215. Each hinge rod 221 is inclined, and the upper end of each hinge rod 221 is rotatably connected to the positioning ring 220, and the lower end of each hinge rod 221 is rotatably connected to the lower end of the lower connecting rod. Figure 4 As shown, when the steel foot fixing seat 215 moves downward, the lower end of the lower connecting rod can be moved downward through the hinge mechanism, thereby causing the gripper 218 to clamp the steel foot of the insulator; the upper end of the return spring 217 abuts against the positioning ring 220, ensuring that the return spring 217 can be compressed when the steel foot fixing seat 215 moves downward, and after the insulator is removed, the return spring 217 can also drive the steel foot fixing seat 215 to return to its original position. Preferably, a limiting plate 222 is provided between the base 212 and the bottom plate 213, and the lower end of the steel foot fixing seat 215 is connected to the limiting plate 222, so that the limiting plate 222 and the steel foot fixing seat 215 can be raised and lowered synchronously. The base 212 is provided with a clearance hole to facilitate the passing of the limiting plate 222 through its middle part, so as to ensure that the steel foot fixing seat 215 has sufficient descent space to achieve the clamping of the insulator by the gripper 218. A pressing cylinder 223 is installed on the bottom plate 213 above the limiting plate 222. The extension rod of the pressing cylinder 223 is set towards the limiting plate 222. In practice, if the clamping effect of the gripper 218 on the insulator is not very good, the limiting plate 222 can also be pressed down by the pressing cylinder 223, so that the steel foot fixing seat 215 moves further down, thereby increasing the clamping force of the gripper 218 on the insulator.

[0049] As a preferred embodiment of this invention, it should be further explained that the workpiece height measuring component 3 includes an upper mounting rod 302 extending along the width direction of the ground rail 1. Both ends of the upper mounting rod 302 are connected to vertical support rods 303 supported on the ground to ensure the stability of the upper mounting rod 302 and to ensure that the height of the upper mounting rod 302 is higher than that of the steel cap ball socket, so that the steel cap ball socket will not be affected when passing under the workpiece height measuring component 3. The two vertical support rods 303 are respectively set on both sides of the ground rail 1, so as not to affect the movement of the workpiece loading and unloading component 2 on the ground rail 1. At least two L-shaped mounting plates distributed along its length direction are detachably connected to the upper mounting rod 302. Each second ranging laser sensor 301 is mounted on one L-shaped mounting plate, which facilitates the loading, unloading and adjustment of the second ranging laser sensor 301.

[0050] As a preferred embodiment of this example, it should be further explained that a material trough mounting platform 505 is fixed to the upper part of the material trough moving assembly 5, and a material trough lifting cylinder 506 is installed in the middle of the material trough mounting platform 505. The telescopic rod of the material trough lifting cylinder 506 is connected to the bottom of the material trough 501, so as to facilitate the control of the lifting of the material trough 501 by the material trough lifting cylinder 506, and then cooperate with the insulators attached to the dip coating head assembly 4 for coating work. At least two second vertical rods 507 are provided around the bottom of the material trough 501. Each second vertical rod 507 slides vertically on the material trough mounting platform 505 through a third sliding bearing 508. The cooperation between the second vertical rod 507 and the third sliding bearing 508 ensures the stability of the material trough 501 when it is lifted.

[0051] As a preferred embodiment of this invention, it should be further explained that the dip coating head assembly 4 includes a head mounting beam 401 and vertical support columns 402 supporting both ends of the head mounting beam 401. The two vertical support columns 402 are respectively arranged on both sides of the ground rail 1, without affecting the movement of the workpiece loading and unloading assembly 2 and the material trough moving assembly 5 on the ground rail 1. At least two electric clamping mechanisms are installed on the head mounting beam 401 along its length, ensuring that each insulator can be attached to one electric clamping mechanism. The electric clamping mechanism includes a mechanism for attaching steel cap balls. The ball head bolt 403 and the rotating shaft 404 for rotating the ball head bolt 403 are included. The connection of the ball head bolt 403 to the steel cap ball socket is existing technology and will not be further described here. The ball head bolt 403 is positioned below the machine head mounting beam 401 to ensure smooth connection to the steel cap ball socket. The rotating shaft 404 is rotatably connected to the machine head mounting beam 401 to ensure its stability. The lower end of the rotating shaft 404 is connected to the ball head bolt 403, ensuring that the rotating shaft 404 can drive the ball head bolt 403 to rotate, thereby driving the insulator in the feed trough 5041. The rotating shaft 404 is rotated internally to achieve uniform coating on the insulator surface. A clamping head 405, located below the machine head mounting beam 401, is sleeved on the rotating shaft 404, ensuring that the clamping head 405 can rotate relative to the rotating shaft 404. Two clamping cylinders 406 are mounted on the machine head mounting beam 401, located on opposite sides of the rotating shaft 404. Connecting plates 407 are fixed to the telescopic rods of the two clamping cylinders 406. The connecting plates 407 can be moved up and down by the two clamping cylinders 406. The outer wall of the clamping head 405 is connected to the connecting plate 407 via ball bearings 408. The central rotating connection is used to drive the clamping head 405 downward through the clamping cylinder 406 to cooperate with the ball head bolt 403 to clamp the steel cap ball socket. That is, during the process of the two clamping cylinders 406 controlling the connecting plate 407 to move downward, the connecting plate 407 can drive the clamping head 405 to move downward, so that the clamping head 405 cooperates with the ball head bolt 403 to clamp the steel cap ball socket. At the same time, the clamping head 405 can rotate relative to the connecting plate 407. When the steel cap ball socket rotates with the insulator, the clamping head 405 can also rotate with the steel cap ball socket to avoid friction between the two.

[0052] Furthermore, a first drive motor 409 is installed at one end of the machine head mounting beam 401. The first drive motor 409 is connected to all rotating shafts 404 through a transmission mechanism, thereby driving all rotating shafts 404 to rotate synchronously. The transmission mechanism includes a transmission sprocket 410 and a transmission chain 411. The motor shaft of the first drive motor 409 and the upper part of each rotating shaft 404 are equipped with transmission sprockets 410. The rotating shaft 404 is provided with one or two transmission sprockets 410 according to the actual situation. The transmission sprockets 410 on the motor shaft of the first drive motor 409 are engaged with the transmission sprockets 410 on the upper part of the adjacent rotating shaft 404 through the transmission chain 411. The transmission sprockets 410 on the upper part of any two adjacent rotating shafts 404 are engaged with the transmission chain 411, thereby ensuring that the first drive motor 409 can drive all rotating shafts 404 to rotate simultaneously, thereby achieving the insulating surface coating.

[0053] As a preferred embodiment of this invention, it should be further explained that both ends of the machine head mounting beam 401 are fixed with a tilting shaft. The two tilting shafts are rotatably connected to the upper ends of the two vertical support columns 402 through bearing seats 412, thereby allowing the machine head mounting beam 401 to rotate between the two vertical support columns 402. This allows the insulator to be tilted at a certain angle within the material trough 501, resulting in a better coating effect. A second drive motor 413 is installed on one vertical support column 402 to drive the tilting shaft, so that the machine head mounting beam 401 can be rotated through the second drive motor 413 to achieve the tilt adjustment of the insulator. A vertical plate 4 is fixed on the other vertical support column 402. 14. The vertical plate 414 is located on the side of the bearing housing 412 away from the machine head mounting beam 401. Multiple U-shaped photoelectric sensors 415 arranged in a ring on the vertical plane are installed on the side of the vertical plate 414 near the bearing housing 412. A light-shielding plate 416 that cooperates with the U-shaped photoelectric sensor 415 is installed on the flip shaft. When the machine head mounting beam 401 rotates, the light-shielding plate 416 will rotate accordingly. When the light-shielding plate 416 cooperates with a U-shaped photoelectric sensor 415, the rotation angle of the machine head mounting beam 401 can be determined. At this time, the signal fed back by the U-shaped photoelectric sensor 415 can be used to control the second drive motor 413 to stop, thereby determining the tilt angle of the insulator, which is convenient for precise control of the tilt angle of the insulator.

[0054] As a preferred embodiment of this invention, it should be further explained that the suspension insulator dipping device also includes a controller and a sealed working chamber. Both ends of the working chamber are equipped with automatic opening and closing doors. When the automatic opening and closing doors are closed, the working chamber is sealed; when open, they facilitate pre-construction operations. The ground rail 1, workpiece loading and unloading assembly 2, workpiece height measuring assembly 3, dipping head assembly 4, and material tank moving assembly 5 are all housed within the working chamber to facilitate sealed operation, thus isolating the coating within the working chamber and benefiting worker health. The working chamber is equipped with a temperature control mechanism and a humidity control mechanism. Existing technologies can be used for these mechanisms, and no restrictions are imposed here, to better control the temperature and humidity during dipping, improving product quality stability and reducing investment in related environmental protection equipment. The controller is electrically connected to the workpiece loading and unloading assembly 2, workpiece height measuring assembly 3, dipping head assembly 4, material tank moving assembly 5, temperature control mechanism, and humidity control mechanism to achieve automated control.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
