Description

Technical Field

[0001] The invention belongs to the field of pickling automatic line design, and specifically relates to an automatic separation and assembly mechanism for inner and outer baskets and a use method. Background Art

[0002] Surface treatment production line refers to an automated production line that uses a series of automated equipment and processes to clean, polish, coat, spray, harden, and other treatments on the surface of parts. According to different treatment processes, surface treatment production lines can be divided into electroplating production lines, coating production lines, chemical oxidation production lines, and thermal spraying production lines. Surface treatment production lines are mainly composed of pre-treatment equipment (such as cleaning machines, rust removers), surface treatment equipment (electroplating tanks, spray chambers, polishing machines or heat treatment furnaces), automated conveying systems (such as conveyor belts, robot arms), and control systems (including computer control systems, sensors, actuators, etc.). Surface treatment equipment is used to perform various treatments on the surface of workpieces. The automated conveying system is used to automatically transport workpieces to various processing stations to achieve continuous operation of the production line. The control system is used to monitor and regulate the operation of the entire production line to ensure the stability and efficiency of the production process.

[0003] The pickling automatic line is the automated production line corresponding to the first step of the surface treatment production line. It mainly removes oxide scale, dirt or impurities on the surface of the material through mechanical and chemical actions in an acid, alkali, high temperature and high humidity environment to improve the purity and quality of the material.

[0004] The pickling automatic line generally uses an inner basket to hold parts. At present, the operator usually puts a batch of parts weighing about 30kg into the inner basket. Both the inner basket and the outer basket are rectangular frames. The height of the inner basket is smaller than that of the outer basket. The inner frame with the parts is then loaded into the outer basket. After the inner basket is put into the outer basket, the gap between the two is 5~6mm, which means that the assembly tooling is completed. Then the outer basket is hung on the production equipment, which means that the parts are put on the line. After the automatic pickling line has finished pickling the parts, the equipment will place the clean parts with inner and outer frames that have been pickled on the end platform of the equipment, and the parts will be taken off the line to complete the pickling. Before the clean parts that have been pickled enter the next process, the inner frame with the parts must be taken out of the outer frame, that is, the inner and outer frames are separated, and the outer frame is left at the station. The assembly tooling and the separation of the inner and outer frames are manually operated. This method of manual assembly and separation greatly consumes the physical strength of the operator and is unsafe. Although the current automation technology is relatively mature, it is still difficult to apply it specifically on the pickling automatic line. There is no simple structure and convenient operation method to solve the problem of manual assembly and separation of inner and outer baskets. Summary of the invention

[0007] A further improvement of the present invention is that the vertical distance between the support rods at the edge and the inner wall of the opening is greater than the diameter of the bottom rod of the outer basket, and the gap between the support surfaces of two adjacent support rods is greater than the diameter of the bottom rod of the outer basket.

[0008] A further improvement of the present invention is that the bottom of the outer basket is a nine-square grid structure, and there are eight support rods, which are arranged to form a square frame structure.

[0010] A further improvement of the present invention is that the support rod is L-shaped, the vertical edge of the support rod is the supporting part of the support rod, the horizontal edge of the support rod is the supporting surface of the support rod, the vertical edge of the support rod is located on the outside, and when the top plate is flush with the support rod, a gap is left between the top plate and the horizontal edge of the adjacent support rod.

[0011] A further improvement of the present invention is that the length of the top plate is 4-6 mm greater than the length of the grid-shaped center of the outer basket bottom, and the width of the top plate is 4-6 mm greater than the width of the grid-shaped center of the outer basket bottom.

[0012] A further improvement of the present invention is that the support surface of the support rod is flush with the upper surface of the workbench, the length of the area enclosed by the support surfaces of all the support rods is greater than the length of the bottom of the inner basket, and the width of the area enclosed by the support surfaces of all the support rods is greater than the width of the bottom of the inner basket.

The top plate supports the outer basket, and the cylinder pushes the piston rod to move vertically downward. The outer basket moves downward under the action of gravity, and the support surfaces of all support rods support the inner basket to realize automatic separation of the inner and outer baskets. The cylinder pushes the piston rod to move vertically downward, so that the distance between the top plate and the supporting surfaces of all supporting rods is greater than the height of the outer basket, and the outer basket is placed in the grid formed by all supporting rods and the openings. The outer basket stops moving after contacting the top plate, and the inner frame is placed on the supporting surfaces of all supporting rods and aligned with the outer basket. The cylinder pushes the piston rod to move vertically upward, and the outer basket moves upward driven by the top plate. When the top plate is flush with the supporting surfaces of all supporting rods, the bottom of the outer basket lifts the bottom of the inner frame, thereby realizing automatic assembly of the inner and outer baskets.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides an automatic separation and assembly mechanism for inner and outer baskets. An opening is provided on a work surface to facilitate the arrangement of support rods distributed in an array. All adjacent support surfaces are arranged at intervals and are located on the same horizontal plane, which can not only constitute the support force surface of the inner basket, but also enable the outer basket to move up and down in the grid-shaped gap formed by all support rods and the opening. The cylinder is arranged at the center of the support rods distributed in an array, and its piston rod can be arranged upward to be located at the center of the opening. After the top of the piston rod is fixed with a top plate whose length and width are both larger than the corresponding length and width of the grid-shaped center of the bottom of the outer basket, the upper surface of the top plate constitutes the support force surface of the outer basket. The top plate has a gap with the adjacent support rods in the vertical direction, and the top plate at the top of the piston rod can be pushed by the cylinder to push the outer basket to move up and down along the hollow bracket in the vertical direction. When the piston rod is retracted downward, the outer basket will sink below the work surface under the action of self-gravity, and since the bottom of the inner basket is an overall plane, the support rod will support the inner basket to remain stationary. After the outer basket moves down, it will stay on the support rod to achieve automatic separation of the inner and outer frames. During assembly, the outer basket moves upward under the action of the top plate, and the bottom of the outer basket can lift the bottom of the inner frame to realize the automatic assembly of the inner and outer baskets. The implementation method of the present invention is that as long as the air intake direction of the cylinder is controlled, the outer basket can be raised or lowered, thereby realizing the separation and assembly of the outer basket and the inner basket in the vertical z-axis direction, and the upper and lower outer baskets of the pickling automatic line can be automatically assembled and separated from the inner basket, and the separated inner and outer baskets can realize automatic diversion. The present invention is safe and reliable, suitable for use on the pickling automatic line, and realizes the separation function requirements of simple structure, reliable positioning, convenient operation and safety, and solves the separation and assembly problems of the inner and outer baskets required for the automatic line and the single station. The present invention uses the pneumatic expansion principle of the cylinder to push the outer basket up and down in the Z-axis direction of the workbench to separate the inner and outer baskets, and solves the heavy physical work of manually separating the inner and outer baskets for pickling in the automatic pickling line. From the perspective of industrialization, it can be promoted to the automatic production line or single station application. It has the value of promotion and application in the current pickling automatic line, and can be used alone, or the workbench can be embedded in the automatic production line.

[0017] The present invention provides a method for using an automatic separation and assembly mechanism for inner and outer baskets. When the inner and outer baskets need to be automatically separated, the initial state of the cylinder is that the piston rod rises, and the cylinder pushes the piston rod to move vertically upward, so that the top plate is flush with the supporting surfaces of all supporting rods, and when the outer basket equipped with the inner frame arrives at the separation station (i.e., the supporting surface of the supporting rod), the grid at the bottom of the outer basket is aligned with the grid formed by all supporting rods and the openings, and the top plate supports the outer basket. The cylinder pushes the piston rod to move vertically downward under the push of high-pressure air, and the outer basket moves downward under the action of gravity. The supporting surfaces of all supporting rods support the inner basket, and the inner basket is automatically transferred away from the separation station. The cylinder uses the high-pressure air to push the piston rod of the piston upward again, so that the lower end of the bottom surface of the outer basket rises to the original position, thereby realizing automatic separation of the inner and outer baskets. When it is necessary to automatically assemble the inner and outer baskets, the initial state of the cylinder is that the piston rod is lowered. The cylinder pushes the piston rod to move vertically downward so that the distance between the top plate and the supporting surfaces of all support rods is greater than the height of the outer basket. The outer basket is placed in the assembly station (in the grid formed by all support rods and the openings). The outer basket stops moving after contacting the top plate. The inner frame is placed on the supporting surfaces of all support rods and aligned with the outer basket. The cylinder, pushed by high-pressure air, pushes the piston rod to move vertically upward, and the outer basket moves upward driven by the top plate. When the top plate is flush with the supporting surfaces of all support rods, the bottom of the outer basket lifts the bottom of the inner frame, realizing automatic assembly of the inner and outer baskets.

[0021] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0022] The present invention provides an automatic separation and assembly mechanism for inner and outer baskets, such as Figure 1 As shown, it mainly includes a work surface 3, a support rod 4 and a cylinder, and the cross-sections of the inner basket 2 and the outer basket 1 are rectangular and the bottoms are both horizontal. The bottom surface of the inner basket 2 is a whole plate with round holes, or a mesh-shaped woven frame or a welded frame. Figure 1 The inner basket 2 provided is an inner basket 2 with circular holes on the bottom surface. The circular holes are arranged in an array on the bottom surface of the inner basket 2 and have a diameter of 10-14 mm. The distance between the centers of two adjacent circular holes is 16-20 mm.

[0023] The bottom of the outer basket 1 is a rectangular grid structure, and a rectangular opening 11 is provided on the work surface 3 near the corresponding position, and its length and width are both greater than or equal to the corresponding length and width of the bottom surface of the outer basket 1. A plurality of vertically distributed support rods 4 are fixed in an array in the opening 11, and the support surfaces on the upper surfaces of all adjacent support rods 4 are arranged at intervals. These support surfaces are all located on the same horizontal plane, and can constitute the support force-bearing surface of the inner basket 2. The outer basket 1 can move up and down in the grid-like gap formed by all the support rods 4 and the opening 11. The cylinder is arranged at the center of the support rods 4 distributed in the array. Therefore, all the support rods 4 need to be arranged into a frame structure with a gap in the center to leave a certain amount of space for the cylinder. This is from Figure 1 The piston rod 5 of the cylinder is placed upright and upward, and is located at the center of the opening 11. A rectangular top plate is fixed on the top of the piston rod 5. The length and width of the top plate are larger than the corresponding length and width of the central grid of the bottom grid of the outer basket 1. The upper surface of the top plate constitutes the supporting force surface of the outer basket 1. The piston rod 5 of the cylinder moves up and down in the vertical z-axis. The top plate can lift up the central area of ​​the lower end surface of the bottom structure of the outer basket 1. In order to facilitate the up and down movement of the top plate, the top plate has a gap with the adjacent support rod 4 in the vertical direction. Due to the viewing angle, the top plate is Figure 1 and Figure 2 The upper surface of the support rod 4 cooperates with the piston rod 5 of the cylinder to support the inner basket 2 after the outer basket 1 moves up and down, so that the inner basket 2 can remain stationary.

[0024] As a specific structure that facilitates the outer basket 1 to move up and down in the grid-like gaps formed by all the support rods 4 and the openings 11, the bottom rod of the outer basket 1 is a rectangular hollow structure, and the outer basket 1 is a rectangular frame structure, that is, the upper end of the bottom is four vertical frames, and the support surfaces on the upper surfaces of all the support rods 4 are rectangular structures of the same size. The length and width of these support surfaces are smaller than the corresponding length and width of the rectangular grid at the bottom of the outer basket 1, and the spacing distance between the support rods 4 located at the edge and the inner wall of the opening 11 in the vertical direction is greater than the diameter of the bottom rod of the outer basket 1, and the gap distance between the support surfaces of two adjacent support rods 4 is greater than the diameter of the bottom rod of the outer basket 1.

[0025] For the pickling automatic line, the bottom of the outer basket 1 is generally a rectangular hollow structure of a nine-square grid structure, so there are eight support rods 4, and the eight support rods 4 are arranged into a square structure frame, distributed around the bottom of the outer basket 1, and the top plate supports the central area of ​​the lower end surface of the nine-square grid structure of the bottom surface of the outer basket 1. The gap distance between the support surfaces of the upper surfaces of two adjacent support rods 4 is equal, and this value is set to S1, and the vertical distance between the support rods 4 located at the edge and the inner wall of the opening 11 is also equal, and this value is set to S2, S1= S2, so that the size is relatively uniform, which is not only convenient for design, but also conducive to the outer basket 1 to maintain a certain stability when it moves up and down driven by the piston rod 5.

[0026] Generally, the length and width of the support surface of the upper surface of the support rod 4 are 3-5 mm smaller than the rectangular grid at the bottom of the outer basket 1, and the gap distance S1 between the support surfaces of the upper surfaces of two adjacent support rods 4 is 3-5 mm larger than W, so the vertical distance S2 between the support rod 4 located at the edge and the inner wall of the opening 11 is also 3-5 mm larger than W. The length and width of the top plate are 4-6 mm larger than the central grid of the grid at the bottom of the outer basket 1.

[0027] The present invention designs the shape of the support rod 4 to be L-shaped, and its vertical side is the supporting component of the support rod 4, which is a plate, and only the horizontal side of the support rod 4 is designed to be a rectangular supporting surface of the support rod 4, and the vertical side of the support rod 4 is further arranged on the outside, which can leave more space for the cylinder and save costs. At the same time, the supporting force can also be satisfied. When the top plate is flush with the support rod 4, there is a gap between the top plate and the horizontal side of the adjacent support rod 4.

[0028] like Figure 2 As shown, the supporting surface of the support rod 4 is flush with the upper surface of the workbench 3, and the top plate can move to a position flush with the workbench 3, so that when the outer basket 1 is placed later, the lower end of its bottom surface is flush with the upper surface of the workbench 3, and the support rod 4 mainly realizes the function of supporting the inner basket 2. Therefore, the length and width of the area enclosed by the supporting surfaces of all support rods 4 are larger than the corresponding length and width of the bottom of the inner basket 2, and the inner basket 2 can be stably supported.

[0029] In order to stably install the work surface 3, the present invention fixes a column 6 at each of the four corners of the lower surface of the work surface 3, so that the bottom of the support rod 4 can be flush with the bottom of the column 6. Further, a bottom plate is added, and the bottoms of the column 6 and the support rod 4 are welded to the horizontally distributed bottom plate. Based on this, the cylinder body of the cylinder can be fixed to the bottom plate by welding. Since the design of the bottom plate can be clearly expressed in words, adding the bottom plate will affect the Figure 1 , Figure 2 The clarity of the base plate Figure 1 and Figure 2 The height of the workbench is generally 1.2m, and the height of the cylinder when the piston rod is not extended is generally 0.3m.

[0030] By pushing the top plate at the top of the piston rod through the cylinder, the outer basket 1 can be pushed up and down along the hollow bracket in the vertical direction. When the piston rod is retracted downward, the outer basket 1 will sink below the work surface 3 under the action of gravity, and since the bottom of the inner basket 2 is an overall plane, the eight support rods 4 will support the inner basket 2 to stay on the work surface 3. After the outer basket 1 moves down, it will stay on the upper part of the work surface 3 to achieve automatic separation of the inner and outer frames. During assembly, the outer basket 1 moves upward under the action of the top plate. The implementation method is that as long as the air intake direction of the cylinder is controlled, the outer basket 1 can be raised or lowered, thereby realizing the separation and assembly of the outer basket 1 and the inner basket 2 in the vertical z-axis direction.

[0031] The outer basket 1 and the inner basket 2 are made of 316L stainless steel or titanium, and the support rod 4 and the cylinder are made of 304 stainless steel.

[0032] The present invention provides an automatic separation and assembly mechanism for inner and outer baskets. When the inner and outer baskets need to be automatically separated, the following steps are performed: Step 1: The initial state of the cylinder is that the piston rod 5 is raised, and the cylinder pushes the piston rod 5 to move vertically upward so that the top plate is flush with the supporting surfaces of all the supporting rods 4; Step 2, when the outer basket 1 with the inner frame 2 arrives at the separation station (i.e., the support surface of the support rod 4), it is kept in the same plane with the support rod 4, the lower end of the bottom surface of the outer basket 1 is flush with the upper surface of the work surface 3, the grid at the bottom of the outer basket 1 is aligned with the grid formed by all the support rods 4 and the openings 11, and the top plate is in contact with the lower end of the bottom surface of the outer basket 1, and the top plate supports the outer basket 1, as shown in FIG. Figure 1 As shown; Step 3: The cylinder receives the driving signal and pushes the piston rod 5 vertically downward under the pressure of 0.4Mpa high-pressure air. The outer basket 1 moves downward under the action of gravity and then falls below the work surface 3. Figure 2 As shown, the supporting surfaces of all support rods 4 support the inner basket 2, and the inner basket 2 is automatically transferred by the push rod to leave the separation station to the drying process. The cylinder receives the driving signal again, and the 0.4Mpa high-pressure air pushes the piston rod 5 of the piston upward to make the lower end of the bottom surface of the outer basket 1 rise to a state flush with the upper surface of the work table 3, thereby realizing the automatic separation of the inner and outer baskets.

[0033] The present invention provides an automatic separation and assembly mechanism for inner and outer baskets. When the inner and outer baskets need to be automatically assembled, the following steps are performed: Step 1, the initial state of the cylinder is that the piston rod 5 is descending, and the cylinder pushes the piston rod 5 to move vertically downward, so that the distance between the top plate and the supporting surfaces of all the supporting rods 4 is greater than the height of the outer basket 1; Step 2, place the outer basket 1 into the assembly station (in the grid formed by all the support rods 4 and the openings 11), stop the outer basket 1 from moving after it contacts the top plate, and place the inner frame 2 on the support surfaces of all the support rods 4 and align it with the outer basket 1; Step 3, the cylinder receives the driving signal and pushes the piston rod 5 to move vertically upward under the push of 0.4Mpa high-pressure air. The outer basket 1 moves upward driven by the top plate. When the top plate is flush with the supporting surfaces of all support rods 4, the bottom of the outer basket 1 lifts the bottom of the inner frame 2, finally realizing the automatic assembly of the inner and outer baskets.
