Description

Technical Field

[0001] This utility model belongs to the technical field of insulator dipping equipment, and specifically relates to a workpiece loading and unloading assembly. 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 automatic insulator dipping and 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 dipping and coating machine head. Then, the dipping and coating machine head clamps the steel cap ball socket at the top of the insulator. Next, the workpiece conveying station reverses and resets. The dipping coating tank moves on the conveyor line to the bottom of the dipping and coating machine head where the insulator has been attached. The dipping and coating machine head and the dipping coating tank work together to coat the surface of the insulator with anti-flashover coating, completing the surface treatment process of the insulator.

[0004] During the automatic dip coating process of the insulators, the insulators will move along with the workpiece conveying station. When the workpiece conveying station is conveying the insulators, the movement of the workpiece conveying station may cause the insulators to become unstable and tilt, which will make it difficult for the dip coating head to clamp the insulators smoothly and affect the dip coating efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a workpiece loading and unloading assembly as a workpiece conveying station, in order to solve the problem of instability in existing workpiece conveying stations when conveying insulators.

[0006] The aforementioned problems exist in the technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A workpiece loading and unloading assembly includes a workpiece mounting frame that moves along a conveyor line. Multiple workpiece clamps, evenly distributed along the width of the conveyor line, are mounted on the upper end of the workpiece mounting frame to clamp an insulator onto the workpiece mounting frame. Each workpiece clamp includes a base plate mounted on the upper end of the workpiece mounting frame. A vertically extending steel foot fixing seat is elastically connected to the center of the upper end of the base plate to support the lower end of the insulator's steel foot. At least two grippers rotatably connected to the base plate are arranged around the steel foot fixing seat. The steel foot fixing seat is connected to all the grippers via a hinge mechanism, so that when the steel foot fixing seat moves downward, the hinge mechanism drives the upper ends of all the grippers to move towards the steel foot fixing seat and clamp the insulator's steel foot.

[0009] As a preferred technical solution of this utility model, a base is provided below the base plate, and the base plate is connected to the base through multiple support columns. The base is slidably connected to the workpiece mounting frame along the width direction of the conveyor line.

[0010] As a preferred technical solution of this utility model, the upper end of the workpiece mounting frame is provided with a mounting plate, and the mounting plate is provided with two first slide rails that are parallel to each other and extend along the width direction of the conveyor line. The lower end of each base is provided with a first slider that is slidably connected to the two first slide rails respectively.

[0011] As a preferred technical solution of this utility model, multiple mounting plates are provided, with each base corresponding to a mounting plate below it. Multiple first vertical limiting posts are installed at the lower end of the mounting plate, and each first vertical limiting post is slidably connected to the workpiece mounting frame through a linear bearing. Multiple electric cylinders are installed on the workpiece mounting frame, and the telescopic rod of each electric cylinder is connected to a mounting plate.

[0012] As a preferred technical solution of this utility model, a limiting plate is provided between the base plate and the base. The lower end of the steel foot fixing seat is connected to the middle part of the limiting plate. The middle part of the base is provided with an avoidance hole to facilitate the limiting plate to pass through and move downward. At least one second vertical limiting post is installed on the limiting plate. The upper part of the second vertical limiting post passes through the base plate and slides with the base plate. A cylinder is installed on the base plate above the limiting plate. The telescopic rod of the cylinder is set towards the limiting plate.

[0013] As a preferred technical solution of this utility model, the lower part of the steel foot fixing seat is a sliding part that matches and slides through the middle of the base plate and is slidably engaged with the base plate. The middle part of the steel foot fixing seat is provided with a limiting part located above the base plate, and a return spring sleeved on the outside of the sliding part is provided between the limiting part and the base plate.

[0014] As a preferred technical solution of this utility model, at least two hinge seats are fixed on the base plate around the steel foot fixing seat. The clamping claw includes an upper clamping rod and a lower connecting rod. The upper clamping rod and the lower connecting rod are integrally formed, and the connection part of the upper clamping rod and the lower connecting rod is rotatably connected to the hinge seat. The upper end of the upper clamping rod is inclined upward towards the steel foot fixing seat, and the lower end of the lower connecting rod is rotatably connected to the hinge mechanism.

[0015] As a preferred technical solution of this utility model, the hinge mechanism includes a positioning ring and at least two hinge rods. The positioning ring is fixedly connected to the steel foot fixing seat above the base plate. Each hinge rod is inclined, and the upper end of each hinge rod is rotatably connected to the positioning ring. The lower end of each hinge rod is rotatably connected to the lower end of the lower connecting rod.

[0016] As a preferred technical solution of this utility model, a U-shaped limiting groove is provided in the middle of the hinge seat. The connection part of the upper clamping rod and the lower connecting rod is rotatably connected in the U-shaped limiting groove through the first rotating shaft. The first rotating shaft passes through the two side walls of the U-shaped limiting groove, and both ends of the first rotating shaft are clamped with snap rings. The two snap rings abut against the outer walls on both sides of the U-shaped limiting groove.

[0017] As a preferred technical solution of this utility model, the upper end of the steel foot fixing seat is provided with a steel foot limiting groove, and the lower part of the steel foot of the insulator is matched and disposed in the steel foot limiting groove.

[0018] Beneficial effects: This utility model installs multiple workpiece clamps evenly distributed along the width of the conveyor line on the workpiece mounting frame, allowing multiple insulators to be mounted simultaneously. This facilitates the simultaneous coating of anti-flashover paint on the surfaces of multiple insulators in subsequent processes, improving work efficiency. Specifically, by elastically connecting the steel foot fixing seat to the base plate, when the insulator is placed on the steel foot fixing seat, the insulator's weight presses down on the steel foot fixing seat, causing it to move downwards. At this time, the steel foot fixing seat drives the hinge mechanism, which in turn causes all the grippers to close, thereby controlling all the grippers to clamp the steel feet on the insulator. This ensures that the insulator can move stably on the conveyor line to below the coating head. When the coating head clamps the insulator, causing it to disengage from the workpiece clamps in the opposite direction, the steel foot fixing seat moves upwards under the action of elastic force. This, in turn, causes all the grippers to open through the hinge mechanism, releasing the restraint on the steel feet. This ensures that the coating head can smoothly clamp the insulator, guaranteeing the efficiency of subsequent coating processes. Attached Figure Description

[0023] 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.

[0024] Example:

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a workpiece loading and unloading assembly, including a workpiece mounting frame 1 that moves along a conveyor line. The lower end of the workpiece mounting frame 1 cooperates with the conveyor line to facilitate movement along the conveyor line. The upper end of the workpiece mounting frame 1 is equipped with multiple workpiece clamps that are evenly distributed along the width direction of the conveyor line, which are used to clamp insulators onto the workpiece mounting frame 1. Multiple insulators can be mounted on the workpiece mounting frame 1 at the same time, which facilitates the simultaneous application of anti-flashover coating to the surfaces of multiple insulators in subsequent processes, thereby improving work efficiency.

[0026] The workpiece chuck includes a base plate 2 mounted on the upper end of the workpiece mounting frame 1, allowing the base plate 2 to move under the control of the conveyor line. A vertically extending steel foot fixing seat 3 is elastically connected to the middle of the upper end of the base plate 2, allowing the steel foot fixing seat 3 to move up and down relative to the base plate 2. This supports the lower end of the steel feet of the insulator, facilitating the placement of the insulator to be coated onto the steel foot fixing seat 3, thus enabling the insulator to move on the conveyor line. At least two grippers 4 are rotatably connected to the base plate 2 around the steel foot fixing seat 3. The number of grippers 4 is set according to actual conditions. When grippers 4 clamp the insulator, if one gripper 4 has two clamping points on the insulator, or if the contact area during clamping is relatively large, then two grippers 4 are preferred. If each clamping jaw 4 has only one clamping point on the insulator and the clamping area is not large, it is preferable to set three or more clamping jaws 4. The setting can be set according to the actual situation and there is no specific restriction. The steel foot fixing seat 3 is connected to all the clamping jaws 4 through the hinge mechanism 5. When the steel foot fixing seat 3 moves downward, the hinge mechanism 5 drives the upper ends of all the clamping jaws 4 to move towards the steel foot fixing seat 3 and clamp the steel foot of the insulator. Then, when the insulator to be coated is placed on the steel foot fixing seat 3, the weight of the insulator will press down on the steel foot fixing seat 3, causing the steel foot fixing seat 3 to move downward. At this time, the steel foot fixing seat 3 will drive the hinge mechanism 5 to move, and the hinge mechanism 5 will drive all the clamping jaws 4 to close, so that all the clamping jaws 4 clamp the steel foot on the insulator, ensuring the stability of the insulator when moving on the conveyor line.

[0027] This invention features multiple workpiece clamps evenly distributed along the width of the conveyor line on a workpiece mounting frame 1. This allows multiple insulators to be mounted simultaneously on the workpiece mounting frame 1, facilitating the simultaneous coating of anti-flashover paint on the surfaces of multiple insulators in subsequent processes, thus improving work efficiency. Specifically, by elastically connecting the steel foot fixing seat 3 to the base plate 2, when an insulator is placed on the steel foot fixing seat 3, the weight of the insulator presses down on the steel foot fixing seat 3, causing it to move downwards. At this time, the steel foot fixing seat 3 drives the hinge mechanism 5, which in turn causes all the grippers 4 to close, thereby controlling all the grippers 4 to clamp the steel feet on the insulator. This ensures that the insulator can move stably on the conveyor line to below the coating head. When the coating head clamps the insulator, causing it to disengage from the workpiece clamps in the opposite direction, the steel foot fixing seat 3 moves upwards under the action of elastic force. This, in turn, causes all the grippers 4 to open through the hinge mechanism 5, releasing the restraint on the steel feet, thus ensuring that the coating head can smoothly clamp the insulator, guaranteeing the efficiency of subsequent coating processes.

[0028] As a preferred embodiment of this example, it should be further explained that a base 6 is provided below the base plate 2. The base plate 2 is connected to the base 6 through multiple support columns 7. The workpiece chuck can be installed on the workpiece mounting frame 1 through the base 6, which also provides more space for the downward movement of the steel foot fixing seat 3, ensuring that the gripper 4 can clamp the insulator. The base 6 is slidably connected to the workpiece mounting frame 1 along the width direction of the conveyor line, thereby facilitating the adjustment of the position of the workpiece chuck according to the actual situation and improving flexibility.

[0029] As a preferred embodiment of this invention, it should be further explained that the upper end of the workpiece mounting frame 1 is provided with a mounting plate 101, and the mounting plate 101 is provided with two parallel first slide rails 102 extending along the width direction of the conveyor line. The lower end of each base 6 is provided with a first slider 601 that is slidably connected to the two first slide rails 102, so that each workpiece chuck can slide stably on the first slide rail 102 with the help of the first slider 601, thereby realizing the sliding adjustment of the workpiece chuck in the width direction of the conveyor line.

[0030] As a preferred embodiment of this invention, it should be further explained that multiple mounting plates 101 are provided, with each base 6 having a corresponding mounting plate 101 below it. Multiple first vertical limiting posts 103 are installed at the lower end of the mounting plate 101, and each first vertical limiting post 103 is slidably connected to the workpiece mounting frame 1 via a linear bearing 104. Multiple electric cylinders 105 are installed on the workpiece mounting frame 1, and the telescopic rod of each electric cylinder 105 is connected to a mounting plate 101. Thus, in practice, when the insulator slides to the bottom of the dip coating machine head, the mounting plate 101 can be driven to rise by the electric cylinder 105, thereby driving the insulator on the workpiece clamp to rise, so as to facilitate the dip coating machine head to clamp the insulator.

[0031] As a preferred embodiment of this example, it should be further explained that a limiting plate 8 is provided between the base plate 2 and the base 6, and the lower end of the steel foot fixing seat 3 is connected to the middle part of the limiting plate 8, so that the limiting plate 8 and the steel foot fixing seat 3 can be raised and lowered synchronously. The middle part of the base 6 is provided with an avoidance hole 602 to facilitate the passing of the limiting plate 8 and its downward movement, without affecting the raising and lowering of the steel foot fixing seat 3. At least one second vertical limiting post 9 is installed on the limiting plate 8. The upper part of the second vertical limiting post 9 passes through the base plate 2 and slides with the base plate 2 to ensure the stability of the steel foot fixing seat 3 when it is raised and lowered. A cylinder 10 is installed on the base plate 2 above the limiting plate 8. The telescopic rod of the cylinder 10 is set towards the limiting plate 8. After the cylinder 10 is extended, it can push the limiting plate 8, causing the limiting plate 8 and the steel foot fixing seat 3 to move further downward, which can increase the closing force of the gripper 3 clamping the insulator, making the insulator more stable when it moves on the conveyor line.

[0032] As a preferred embodiment of this invention, it should be further explained that the lower part of the steel foot fixing seat 3 is a sliding part that matches and slides through the middle of the base plate 2 and is slidably engaged with the base plate 2, so that the steel foot fixing seat 3 can stably achieve elastic sliding on the base plate 2. The middle part of the steel foot fixing seat 3 is provided with a limiting part located above the base plate 2. A return spring 11 is provided between the limiting part and the base plate 2 and sleeved outside the sliding part. The return spring 11 provides an upward elastic force to the steel foot fixing seat 3, ensuring that when the insulator is pressed on the steel foot fixing seat 3, the steel foot fixing seat 3 can move downward, and after the insulator is disengaged, the steel foot fixing seat 3 can automatically reset.

[0033] As a preferred embodiment of this example, it should be further explained that at least two hinge seats 201 are fixed on the base plate 2 around the steel foot fixing seat 3. The hinge seats 201 correspond one-to-one with the grippers 4. The grippers 4 include an upper clamping rod and a lower connecting rod. The upper clamping rod and the lower connecting rod are integrally formed to ensure the stability of the structure. The connection part of the upper clamping rod and the lower connecting rod (which can be understood as the middle part of the gripper 4) is rotatably connected to the hinge seat 201, so that the gripper 4 can swing relative to the hinge seat 201. The upper end of the upper clamping rod is inclined upward towards the steel foot fixing seat 3, and the lower end of the lower connecting rod is rotatably connected to the hinge mechanism 5. Thus, during the process of fixing the steel foot 3, the steel foot fixing seat 3 will press down the lower end of the connecting rod through the hinge mechanism 5, thereby causing the upper end of the upper clamping rod to swing towards the steel foot fixing seat 3, thereby clamping the steel foot.

[0034] As a preferred embodiment of this invention, it should be further explained that the hinge mechanism 5 includes a positioning ring 501 and at least two hinge rods 502. The positioning ring 501 is fixedly connected to the steel foot fixing seat 3 above the base plate 2. It can be welded or integrally formed, or it can be detachably connected by bolts or the like. Each hinge rod 502 is inclined, and the upper end of each hinge rod 502 is rotatably connected to the positioning ring 501. The lower end of each hinge rod 502 is rotatably connected to the lower end of the lower connecting rod, ensuring the stability and flexibility of the hinge rod 502.

[0035] As a preferred embodiment of this invention, it should be further explained that the hinge seat 201 is provided with a U-shaped limiting groove in the middle, similar to an horn. The connection part of the upper clamping rod and the lower connecting rod is rotatably connected to the U-shaped limiting groove through the first rotating shaft. The first rotating shaft passes through the two side walls of the U-shaped limiting groove, ensuring that the gripper 4 can rotate stably on the hinge seat 201. Both ends of the first rotating shaft are engaged with snap rings, and the two snap rings abut against the outer walls on both sides of the U-shaped limiting groove, making assembly and disassembly simple.

[0036] As a preferred embodiment of this invention, it should be further explained that the upper end of the steel foot fixing seat 3 is provided with a steel foot limiting groove 301, and the lower part of the steel foot of the insulator is matched and disposed in the steel foot limiting groove 301. This makes the support of the steel foot fixing seat 3 for the insulator more stable, and at the same time does not affect the clamping of the upper part of the steel foot by the gripper 4, thereby ensuring the stability of the insulator when it moves on the conveyor line.

[0037] 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.
