Description

Technical Field

[0001] This invention relates to the field of composite insulator processing, and in particular to a cleaning system for end fittings of composite insulators. Background Technology

[0002] In the process of producing composite insulator fittings, the fittings need to be cleaned and rust-proofed before packaging. The traditional cleaning method involves operators cleaning the fittings in separate spray rough cleaning areas, ultrasonic rough cleaning areas, and rinsing areas, and then spraying rust-proofing oil. The disadvantages of this method are that each process needs to be carried out separately, and the water in the fitting crimping holes needs to be spun dry after each process is completed. This results in low cleaning efficiency and high labor intensity.

[0003] In response to the above phenomenon, patent CN201420691851.0 proposes a composite insulator hardware cleaning device, including a frame, and the inner walls of the spray coarse washing box, ultrasonic coarse washing box, first bubbling rinsing box, second bubbling rinsing box and rust-preventive oil spray box inside the frame are all inclined inward from top to bottom; a chain conveyor belt extending along the long axis of the frame is provided on the frame.

[0004] The cleaning device in the aforementioned patent requires the composite insulator fittings to be placed on a conveyor belt and cleaned in different cleaning areas as the belt moves along. This cleaning method has the following drawbacks: First, this conveying method necessitates that the fittings be placed flat on the conveyor belt. Since the fittings are typically fixed to the composite insulator using hot pressing or crimping processes, they must be air-dried after cleaning. Otherwise, residual moisture can easily lead to serious accidents such as core rod breakage. The aforementioned cleaning method only utilizes an inclined conveyor belt... Pour out the cleaning fluid from the fittings. This method cannot completely drain the water from the fittings, inevitably leaving residual moisture. This necessitates a second drying process after cleaning, which is very troublesome. Secondly, most existing composite insulator fittings are cylindrical in structure. Therefore, when using a conveyor belt to transport the fittings, some fittings may tumble on the conveyor belt. This causes these fittings to remain in a certain cleaning area for too long. Especially since the entire cleaning process includes ultrasonic vibration cleaning, which can cause vibration of the cleaning fluid, the probability of fittings tumbling is increased. This can negatively impact the surface quality and performance of the fittings. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cleaning system for the end fittings of composite insulators that ensures the cleaning effect of the fittings and avoids secondary processing.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a composite insulator end fitting cleaning system, the innovation of which is: including a material frame, a feeding assembly, a cleaning assembly, a discharging assembly and a transfer assembly; A material frame for temporarily placing composite insulator fittings, the material frame including a material frame body and a support column disposed inside the material frame body; A feeding assembly used to receive composite insulating hardware delivered from the previous process; A feeding assembly used to transport the cleaned composite insulator fittings to the next process; A cleaning assembly for cleaning hardware, the cleaning assembly including a cleaning bracket disposed between a loading assembly and a unloading assembly, the cleaning bracket being provided with a cleaning tank and a drying tank; A transfer component is used to move the material frame between the feeding component, the cleaning component and the unloading component. The transfer component includes a transfer bracket and a transfer trolley set on the transfer bracket. The transfer trolley is also equipped with a material claw for gripping the material frame.

[0007] Furthermore, the material frame includes a material frame body, which is a rectangular hollow frame structure with an open top. A pair of parallel lifting crossbars are also provided on the upper surface of the material frame body. Support columns for fixed-point support of composite insulator hardware are provided inside the material frame body. The support columns are arranged in a rectangular array inside the material frame body. The feeding assembly includes a feeding bracket, on which a feeding conveyor belt is mounted; The feeding assembly includes a feeding bracket, on which a feeding conveyor belt is provided; The cleaning assembly includes a cleaning support frame, on which a cleaning tank and a drying tank are provided. There are several cleaning tanks and one drying tank, and all the cleaning tanks and drying tanks are arranged in a straight line. The cleaning tanks store cleaning liquid and are equipped with an ultrasonic generator. The bottom of the drying tank has several drying holes. The inner walls of the cleaning tanks and the drying tanks are also equipped with support components for supporting the material frame. The side wall of the drying tank is also equipped with a row of fans. The transfer assembly includes a transfer bracket, and a transfer trolley is also arranged on the transfer bracket above the cleaning assembly. The transfer trolley moves horizontally along the transfer bracket, and the direction of movement of the transfer trolley is consistent with the distribution direction of the cleaning tank and the drying tank. The bottom of the transfer trolley is also provided with a material frame gripping assembly. The material frame gripping assembly includes an array of gripping claws. Each set of gripping claws consists of four claws, and every two claws work together to grip the same lifting crossbar. The transfer trolley also moves up and down under the drive of a lifting assembly, and drives the claws to move up and down synchronously.

[0008] Furthermore, the support column is inclined.

[0009] Furthermore, a limiting component is also provided on the feeding bracket at the discharge side of the feeding conveyor belt. The limiting component includes a pair of limiting plates arranged side by side on the feeding bracket.

[0010] Furthermore, each of the aforementioned cleaning tanks is connected to a circulation assembly, which includes a recycled water tank, a concentrate tank, a stock solution tank, a circulation tank, a cleaning tank, and a filter. The filter has an inlet, a clean liquid outlet, a waste liquid outlet, and a backwash port. The filter's inlet is connected to the outlet of the circulation tank via a pipe, and the circulation tank's inlet is connected to the outlet of the stock solution tank. A filter is also installed between the stock solution tank and the circulation tank. The stock solution tank's inlet is connected to each cleaning tank via a pipe. The filter's clean liquid outlet is connected to the inlet of the recycled water tank via a pipe, and the recycled water tank's outlet is connected to each cleaning tank. The filter's waste liquid outlet is connected to the inlet of the concentrate tank, and the filter's backwash port is connected to the outlet of the cleaning tank via a pipe.

[0011] Furthermore, the concentrate tank, stock solution tank, circulation tank, and cleaning tank are all installed on a circulation base. The circulation base includes a base body, which is a cuboid frame structure. The base body is divided into four regions, which are sequentially defined as the first region, the second region, the third region, and the fourth region. The first region and the second region are arranged vertically, as are the third region and the fourth region. The third region is located next to the first region, and the fourth region is located next to the second region. The concentrate tank is located in the first region, the stock solution tank is located in the second region, the circulation tank and the cleaning tank are both located in the third region, and the fourth region is an unused area for the arrangement of pipelines.

[0012] Furthermore, the support assembly includes several support rods distributed on the inner wall of the washing tank or drying tank. Each support rod is inclined, and the size of the outline enclosed by the bottom surface of each support rod is smaller than the size of the material frame, while the size of the outline enclosed by the top surface of each support rod is larger than the size of the material frame. This ensures that when the material frame is supported on the support rods, there is a gap between the bottom surface of the material frame and the bottom of the inner wall of the washing tank or drying tank.

[0013] Furthermore, a transition bracket is provided between the transfer trolley and the transfer support. The transfer trolley is a cuboid frame structure, and the transition bracket is a rectangular support. The transition bracket is located inside the transfer trolley, and the length of the transition bracket is less than the length of the transfer trolley, while the width of the transition bracket is greater than the width of the transfer trolley. The cooperation between the transfer trolley and the transition support is as follows: a pair of parallel horizontal guide rails are installed at the top of the transition support, and the horizontal guide rails extend along the arrangement direction of the washing tank and the drying tank. A horizontal slider that cooperates with the horizontal guide rails is also installed on the transfer trolley. The transfer trolley is driven to move horizontally by a linear driver installed on the transition support. The lifting assembly consists of a lifting connecting rod on the upper and lower sides of the transition bracket, and lifting sprockets on the upper and lower sides of the transfer bracket. A lifting chain connects the lifting connecting rods and the lifting sprockets. One side of the lifting chain is connected to the upper lifting connecting rod on the transition bracket, and the other side passes through the upper and lower lifting sprockets in sequence before connecting to the lower lifting connecting rod on the transition bracket, forming a closed loop. One of the lifting sprockets is driven to rotate by a lifting motor, thereby driving the transition bracket to move up and down, thus realizing the up and down movement of the transfer trolley and the material claw.

[0014] Furthermore, a protective component is provided on the outside of the cleaning component and the transfer component. The protective component includes a protective cover that surrounds both the cleaning component and the transfer component. On both sides of the protective cover, there is a feeding opening that allows the discharge side of the feeding component to extend into the material and a discharging opening that allows the feeding side of the unloading component to extend into the material. A first guide component is also provided at the feed opening to guide a pair of material frames. The first guide component includes a pair of first guide plates arranged side by side on both sides of the feed opening. A first guide slope is also provided on the side of the two first guide plates near the feeding component. A second guide component is also provided at the discharge opening to guide a pair of material frames. The second guide component includes a pair of second guide plates arranged side by side on both sides of the discharge opening, and a second guide slope is provided on the upper side of the two second guide plates.

[0015] The advantages of this invention are as follows: The cleaning system of this invention adopts the cooperation of a material frame, a feeding component, a cleaning component, a discharging component, and a transfer component. Through the cooperation of the material frame and the transfer between the cleaning tank and the drying tank, the cleaning of hardware is completed. Compared with the cleaning of conveyor belts, the entire process can ensure the cleaning time of each batch of hardware, thereby ensuring the cleaning effect. In addition, with the design of the drying tank, the hardware can be automatically dried in time after cleaning. The entire cleaning system realizes automated processing from feeding, cleaning, drying to discharge, which is very convenient.

[0016] The material frame is designed with a hollowed-out frame body and internal support columns arranged in a rectangular array. This design allows multiple hardware fittings to be placed vertically in the frame, which facilitates cleaning and avoids interference between them. It also allows the cleaning fluid to flow smoothly out of the hardware fitting cavity, preventing liquid residue in the hardware fitting cavity.

[0017] The design of the support components is intended to provide auxiliary support for the material frame when it is placed in the cleaning tank or drying tank. This prevents the material frame from being too close to the bottom of the cleaning tank or drying tank, which would prevent the cleaning solution in the cleaning tank from smoothly entering the inner cavity of the hardware to clean it, or prevent the air from smoothly entering the inner cavity of the hardware to dry it. This provides a good foundation for the smooth cleaning and drying of the hardware.

[0018] The setup of the concentrate tank, raw material tank, circulation tank, and cleaning tank is optimized by installing them all on a single circulation base. This reduces the space required for each tank, increases space utilization, and minimizes the area occupied in the factory. Furthermore, it facilitates unified observation and management of each tank by personnel.

[0019] The design of the first and second guide components is to guide the position of the material frame when it enters the loading position and when the cleaned material frame is placed in the discharge position, ensuring the accuracy of the material frame's movement. This provides a stable foundation for the subsequent transfer components to accurately grab the material frame from the loading component and place it on the unloading component.

[0025] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0026] like Figures 1-5 The composite insulator end fitting cleaning system shown includes a material frame, a feeding assembly, a cleaning assembly, a discharging assembly, and a transfer assembly.

[0027] A material frame 1 is used for temporarily placing composite insulator fittings. The material frame 1 includes a material frame body and a support column disposed within the material frame body.

[0028] Specifically, the material frame 1 includes a material frame body 11, which is a rectangular hollow frame structure with an open top. A pair of parallel lifting crossbars 12 are also provided on the upper surface of the material frame body 11. Both sides of the lifting crossbars 12 are welded and fixed to the material frame body 11 through a pair of connecting rods 13. The two connecting rods 13 of the same pair are arranged in an inverted V-shape. Support columns 14 for fixed-point support of composite insulator fittings are provided inside the material frame body 11. The support columns 14 are arranged in a rectangular array inside the material frame body 11, and the top of the support columns 14 is arc-shaped. The design of the material frame 1, with its hollow material frame body 11 and the rectangular array of support columns 14 inside, facilitates the vertical placement of multiple fittings within the material frame. This facilitates cleaning and avoids interference between them. It also allows cleaning fluid to flow smoothly out of the fitting cavities, preventing liquid residue within the fitting cavities.

[0029] The support columns 14 are inclined, and all support columns 14 are inclined in the same direction. The design of the support columns 14 allows the hardware to be inclined during the cleaning process. This design facilitates the cleaning fluid to clean the grooves, corners and other areas of the hardware, improving the cleaning effect.

[0030] Inside the material frame body 11, there are also several protective nets 15 formed by horizontally and vertically distributed metal wires connected in a grid pattern. The protective nets 15 are located at the bottom of the material frame body 11 and on the inner walls of the four sides of the material frame body 11. The anti-slip nets 15 play a protective role for the hardware inside the material frame body 11. Even if the hardware is separated from the support column 14 due to human error or other factors during conveying, cleaning, drying, etc., the separated hardware will remain inside the material frame body 11 and will not fall directly outside the material frame body 11.

[0031] The feeding assembly is used to receive composite insulating hardware from the previous process. The feeding assembly includes a feeding bracket 2, on which a feeding conveyor belt is installed. The feeding conveyor belt is driven by a feeding motor installed on the feeding bracket 2.

[0032] The unloading assembly is used to transport the cleaned composite insulator fittings to the subsequent process. The unloading assembly includes a unloading bracket 3, on which an unloading conveyor belt is installed. The unloading conveyor belt is driven by an unloading motor installed on the unloading bracket 3.

[0033] A cleaning assembly for cleaning hardware includes a cleaning bracket 5 disposed between a loading assembly and a unloading assembly, and a cleaning tank 51 and a drying tank 52 are provided on the cleaning bracket 5.

[0034] Specifically, the cleaning assembly includes a cleaning support 5, on which a cleaning tank 51 and a drying tank 52 are provided. Both the cleaning tank 51 and the drying tank 52 are hollow rectangular trough structures with open tops. There are three cleaning tanks 51 and one drying tank 52, and all the cleaning tanks 51 and drying tanks 52 are arranged in a straight line. The cleaning tank 51 stores cleaning fluid and also contains an ultrasonic generator. The bottom of the drying tank 52 has several drying holes 521, which are circular holes and are arranged in a rectangular array at the bottom of the trough. Below the drying tank 52, there is a fan connected to the drying holes 521. A row of fans 522 is also provided on the side wall of the drying tank 52. Support components for supporting the material frame are also provided on the inner walls of the cleaning tank 51 and the drying tank 521.

[0035] like Figure 5As shown in the schematic diagram, the support assembly includes several support rods 53 distributed on the inner wall of the washing tank 51 or the drying tank 52. Each support rod 53 is inclined, and the size of the outline enclosed by the bottom surface of each support rod 53 is smaller than the size of the material frame, while the size of the outline enclosed by the top surface of each support rod 53 is larger than the size of the material frame. This results in a gap between the bottom surface of the material frame body 11 and the bottom of the inner wall of the washing tank 51 or the drying tank 52 when the material frame body 11 is supported on each support rod 53. The design of the support component is intended to provide auxiliary support for the material frame when it is placed in the cleaning tank 51 or the drying tank 52. This prevents the material frame from being too close to the bottom of the cleaning tank 51 or the drying tank 52, which would prevent the cleaning fluid in the cleaning tank 51 from smoothly entering the inner cavity of the hardware to clean it, or prevent the air from smoothly entering the inner cavity of the hardware to dry it. This provides a good foundation for the smooth cleaning and drying of the hardware.

[0036] Each cleaning tank 52 is also connected to a circulation component, such as Figure 4 As shown in the schematic diagram, the circulation assembly includes a recycled water tank, a concentrate tank 6, a stock solution tank 61, a circulation tank 62, a cleaning tank 63, and a filter 64. The filter 64 has an inlet, a clean liquid outlet, a waste liquid outlet, and a backwash port. The inlet of the filter 64 is connected to the outlet of the circulation tank via a pipe, and the inlet of the circulation tank is connected to the outlet of the stock solution tank. A filter 65 is also installed between the stock solution tank 61 and the circulation tank 62. The inlet of the stock solution tank 61 is connected to each cleaning tank 51 via a pipe, and the clean liquid outlet of the filter 64 is connected to the inlet of the recycled water tank via a pipe. The recycled water tank is located beside the cleaning assembly, and its outlet is connected to each cleaning tank 51. The waste liquid outlet of the filter 64 is connected to the inlet of the concentrate tank 6, and the backwash port of the filter 64 is connected to the outlet of the cleaning tank 63 via a pipe.

[0037] During operation, the cleaning waste liquid after multiple cleanings in the cleaning tank 51 is first pumped into the raw liquid tank 61. The filter 64 is turned on, and the pump first filters the waste liquid in the raw liquid tank 61 through the filter 65 to remove particulate impurities. The filtered waste liquid then enters the circulation tank 62, and then enters the filter 64 again for treatment. The treated water is divided into two parts: the recycled water enters the recycled water tank for use, and the wastewater enters the concentrate tank 6 for centralized treatment.

[0038] The concentrate tank 6, the stock solution tank 61, the circulation tank 62, and the cleaning tank 63 are all installed on a circulation base. The circulation base includes a base body 66, which is a cuboid frame structure. The base body is divided into four regions, which are defined as the first region, the second region, the third region, and the fourth region in sequence. The first region and the second region are distributed vertically, and the third region and the fourth region are distributed vertically. The third region is located next to the first region, and the fourth region is located next to the second region. The concentrate tank 6 is located in the first region, the stock solution tank 61 is located in the second region, the circulation tank 62 and the cleaning tank 63 are both located in the third region, and the fourth region is an empty area for the arrangement of pipelines. The concentration tank 6, raw liquid tank 61, circulation tank 62 and cleaning tank 63 are arranged in a reasonable manner, with all of them installed on a circulation base. This reduces the space required for each tank, increases space utilization, and reduces the area occupied in the factory. It also facilitates unified observation and management of each tank by personnel.

[0039] A transfer component is used to move the material frame between the feeding component, the cleaning component and the unloading component. The transfer component includes a transfer bracket 4 and a transfer trolley 41 set on the transfer bracket 4. The transfer trolley 41 is also equipped with a material claw 42 for gripping the material frame.

[0040] Specifically, the transfer component includes a transfer support 4, which is a hollow cuboid frame structure. A transfer trolley 41 is also installed on the transfer support 4 above the cleaning component. The transfer trolley 41 moves horizontally along the transfer support, and the direction of movement of the transfer trolley 41 is consistent with the distribution direction of the cleaning tank 51 and the drying tank 52. A material frame gripping component is also installed at the bottom of the transfer trolley 41. The material frame gripping component includes five sets of gripping claws. Each set of gripping claws consists of four claws 42. Every two claws work together to grip the same lifting crossbar 12. The lower part of the claw 42 is a hook structure. The transfer trolley 41 is also lifted up and down by a lifting component, which drives the claws 42 to lift up and down synchronously.

[0041] A transition support 43 is also provided between the transfer trolley 41 and the transfer bracket 4. The transfer trolley is a cuboid frame structure, and the transition support 43 is a rectangular support. The transition support 43 is located inside the transfer trolley 41, and the length of the transition support 43 is less than the length of the transfer trolley 41, while the width of the transition support 43 is greater than the width of the transfer trolley 41.

[0042] The cooperation between the transfer trolley 41 and the transition bracket 43 is as follows: a pair of parallel horizontal guide rails are installed at the top of the transition bracket 43, and the horizontal guide rails extend along the arrangement direction of the washing tank 51 and the drying tank 52. A horizontal slider that cooperates with the horizontal guide rails is also installed on the transfer trolley 41. The transfer trolley is driven to move horizontally by a linear actuator installed on the transition bracket 43. In this embodiment, the linear actuator can adopt a similar drive structure such as a cylinder, hydraulic cylinder, or lead screw and nut pair.

[0043] The lifting assembly consists of a lifting connecting rod 44 on the upper and lower sides of the transition bracket 43, and lifting sprockets 45 on the upper and lower sides of the transfer bracket 4. A lifting chain 46 is connected between the lifting connecting rod 44 and the lifting sprocket 45. One side of the lifting chain 46 is connected to the upper lifting connecting rod 44 on the transition bracket 43, and the other side of the lifting chain 46 passes over the upper and lower lifting sprockets 45 in sequence and connects to the lower lifting connecting rod 44 on the transition bracket 43 to form a closed loop. One of the lifting sprockets 45 is driven to rotate by a lifting motor 46, thereby driving the transition bracket 43 to move up and down, thus realizing the up and down movement of the transfer trolley 41 and the material claw 42.

[0044] A limiting component is also provided on the feeding bracket 2 at the discharge side of the feeding conveyor belt. The limiting component includes a pair of limiting plates arranged side by side on the feeding bracket 2. The cooperation of the two limiting plates at the discharge side of the feeding conveyor belt serves to limit the conveying stroke of the material frame body 11 on the feeding conveyor belt in one direction, so as to prevent the material frame body 11 from exceeding the limit on the feeding conveyor belt and affecting the automatic gripping of the material frame body 11 by the subsequent transfer components.

[0045] A protective component is also provided on the outside of the cleaning component and the transfer component. The protective component includes a protective cover that surrounds both the cleaning component and the transfer component. On both sides of the protective cover, there is a feed opening that allows the discharge side of the feeding component to extend into the feed, and a discharge opening that allows the feed side of the unloading component to extend into the discharge. The design of the protective component is to provide physical isolation and protection for the cleaning component and the transfer component. This is to prevent external debris from affecting the smooth operation of the cleaning component and the transfer component, and also to prevent personnel from easily coming into contact with the cleaning component, which could affect the cleaning of the hardware.

[0046] A first guide assembly is also provided at the feed opening of the protective cover to guide a pair of material frame bodies 11. The first guide assembly includes a pair of first guide plates arranged side by side on both sides of the feed opening. A first guide ramp is also provided on the side of the two first guide plates near the feeding assembly.

[0047] A second guide assembly is also provided at the discharge opening of the protective cover to guide a pair of material frame bodies 11. The second guide assembly includes a pair of second guide plates arranged side by side on both sides of the discharge opening, and a second guide ramp is provided on the upper side of the two second guide plates. The design of the first and second guide assemblies is to guide the position of the material frame when it enters the loading position and when the cleaned material frame is placed at the discharge position, ensuring the accuracy of the material frame's movement. This provides a stable foundation for the subsequent transfer assembly to accurately grab the material frame from the loading assembly and place it on the unloading assembly.

[0048] Working principle: When cleaning the fittings, the fittings processed in the previous process are first placed manually on the support columns 14 inside the main body 11 of the material frame. Then, the main body 11 of the material frame containing the fittings is conveyed by the feeding conveyor belt. When the main body 11 of the material frame reaches the feeding position, the feeding conveyor belt stops conveying. In subsequent practical applications, the position of the main body 11 of the material frame can be detected by installing a sensor on the feeding bracket at the feeding position, and the feeding conveyor belt can be controlled in conjunction with a PLC controller.

[0049] When the material frame body 11 reaches the loading position, the transfer trolley 41 is in the first position. At this position, the five sets of gripping claws are respectively located above the discharge side of the loading conveyor belt, the three washing tanks 51, and the drying tank 52. In the vertical direction, each claw 42 is located on the side of the corresponding lifting crossbar 12 near the loading component. Then, the lifting motor 46 works to drive the transfer trolley 41 downward until the transfer trolley 41 moves to the second position. At this position, the hook structure of the claw 42 is diagonally below the lifting crossbar 12. Then, the linear drive drives the transfer trolley 41 to move horizontally towards the discharge component, so that the transfer trolley 41 moves to the third position. At this position, the hook structure of the claw 42 is... The hook structure is located directly below the lifting crossbar 12. Then, the lifting motor 46 operates to drive the transfer trolley 41 upward. As the transfer trolley 41 moves upward, the hook structure of the material claw 42 hooks onto the lifting crossbar 12, thereby driving the material frame body 11 upward synchronously. The lifting motor 46 stops operating after the transfer trolley 41 moves to the fourth position. The height of the transfer trolley 41 at the fourth position is the same as that at the first position. Horizontally, the transfer trolley 41 at the fourth position is closer to the discharge assembly than the transfer trolley 41 at the first position. Then, the linear actuator drives the transfer trolley 41 to move towards the discharge assembly until the transfer trolley 41... Moving to the fifth position, at this position, the five sets of gripping claws are respectively positioned above the three cleaning tanks 51, one drying tank 52, and the feeding side of the discharge component. Then, the lifting motor 46 operates, driving the transfer trolley 41 downwards until the transfer trolley 41 moves to the sixth position. At this position, the height of the transfer trolley 41 is the same as that of the transfer trolley in the third position. Since the hook structure of the gripper 42 is directly below the lifting crossbar 12, the material frame body 11 will be supported on the support component of the first cleaning tank 51. Then, the linear drive drives the transfer trolley 41 to move towards the feeding component until the transfer trolley 41 moves to the seventh position. At this time, the hook structure of the material claw 42 is located diagonally below the lifting crossbar 12. Then, the lifting motor 46 works to drive the transfer trolley 41 upward. While the transfer trolley 41 is moving upward, the hook structure of the material claw 42 will be offset from the lifting crossbar 12 and will not touch the lifting crossbar 12. That is, at this time, the first material frame has been placed in the first cleaning tank 51 for cleaning. The transfer trolley 41 will move upward to the eighth position under the drive of the lifting motor 46. At this position, the height of the transfer trolley 41 is the same as the height of the transfer trolley 41 at the first position. Then, the transfer trolley 41 is driven by the linear driver to move towards the feeding component until the transfer trolley 41 moves from the eighth position to the first position, completing one action cycle.

[0050] As the aforementioned transfer trolley 41 continues its cyclical operation, it will grab the second material frame on the loading conveyor belt and place it into the first cleaning tank 51 for cleaning. While grabbing the second material frame, the transfer trolley 41 will simultaneously grab the first material frame, causing the first material frame to move from the first cleaning tank 51 to the second cleaning tank 51. This process is repeated until the first material frame is placed on the unloading conveyor belt under the drive of the transfer trolley 41 and transported by the unloading conveyor belt to the first process, completing the cleaning process of the hardware in the first material frame.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
