Abstract

The present application relates to the technical field of liquid accumulator automatic assembly equipment, and is a three-section type liquid accumulator automatic assembly equipment, comprising: the rear end of an inclined chute is connected with the front end of an input conveyor belt, and a flow outlet is formed in the rear end of the inclined chute; a convex sample selection plate is connected with the front end of the input conveyor belt, and the convex end of the convex sample selection plate and the side wall of the flow outlet form a sample screening space, so that the concave-down baffle conveyed by the input conveyor belt falls from the sample screening space, and the concave-up baffle flows through the sample screening space and slides into the inclined chute. The device can automatically screen the state of the baffle. The concave-down baffle cannot pass through the sample selection plate due to the interference between the concave surface and the convex part of the sample selection plate, and finally falls from the sample screening space to the collection area below. The concave-up baffle can smoothly pass through the sample screening space and enter the inclined chute for continuous conveying. Thus, the defective products caused by human operation omission in the feeding process are reduced, and the production cost of the liquid accumulator automatic assembly equipment is reduced.

Description

Technical Field

[0001] This invention relates to the field of automatic liquid storage tank assembly equipment, specifically a three-stage automatic liquid storage tank assembly equipment and its manufacturing process. Background Technology

[0002] The automated liquid reservoir assembly equipment is an integrated system combining mechanical, electrical, pneumatic, and visual inspection technologies. It is specifically designed for efficient, precise, and unmanned operation of the liquid reservoir assembly process. Its core system includes: a conveying system that automates component feeding via vibratory feeders, conveyor belts, or robotic arms; an assembly unit using multi-axis robotic arms and customized fixtures for precise gripping, positioning, and assembly; a processing module integrating laser welding, spinning sealing, and pressure testing; a visual inspection system and a functional testing system; and a core control system based on a PLC or industrial computer. This allows for the assembly and fitting of the housing, partitions, lower cover, iron pipes, gaskets, and upper cover.

[0003] During assembly, the housing needs to mate with the concave surface of the partition. Currently, partitions are typically fed manually, with operators placing them on a vibratory feeder in a designated position. However, manual feeding is prone to errors. Operators may overlook errors when visually inspecting them, making timely correction difficult. This can lead to defective products being assembled onto the other side of the housing later, increasing production costs when there are many defective products. Therefore, the production cost of existing automated liquid storage tank assembly equipment is relatively high. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic assembly equipment and manufacturing process for a three-stage liquid storage tank.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automatic assembly device for a three-section liquid reservoir is provided, including: a partition loading device;

[0007] The partition feeding device includes a partition conveying mechanism, which includes an input conveyor belt, a convex sample selection plate, an inclined slide, and a feed belt. The rear end of the inclined slide is connected to the front end of the input conveyor belt, and an outlet is provided on the rear end of the inclined slide. The convex sample selection plate is connected to the front end of the input conveyor belt, and the protruding end of the convex sample selection plate forms a sieving space with the side wall of the outlet, so that the partition with the concave surface facing down fed by the input conveyor belt falls out of the sieving space, and the partition with the concave surface facing up flows through the sieving space and slides into the inclined slide.

[0008] In some embodiments, the partition feeding device further includes a flipping mechanism, which is installed on the feeding belt to flip the partitions on the feeding belt.

[0009] The three-section liquid storage automatic assembly equipment also includes a partition assembly device, which includes a partition positioning mechanism and a partition pressing mechanism. The partition positioning mechanism includes a partition translation module, a partition clamping assembly for clamping the partition conveyed by the feed belt, and a partition rotation driver for driving the partition clamping assembly to rotate. The output end of the partition translation module is connected to the partition rotation driver, and the output end of the partition rotation driver is connected to the partition clamping assembly to cooperate with the flipping mechanism so that the concave surface of the partition is aligned with the housing during processing.

[0010] The working end of the partition pressing mechanism presses the partition on the partition clamping assembly against the housing.

[0011] In some embodiments, the material turning mechanism includes a material turning driver and a rotating shaft. The material turning driver is mounted on the feed belt, and the output end of the material turning driver is connected to the rotating shaft to drive the rotating shaft to rotate on the feed belt. The rotating shaft is provided with a magnetic part so that the rotation of the magnetic part can drive the partition to turn over on the feed belt.

[0012] In some embodiments, the partition positioning mechanism further includes a partition lifting assembly that lifts the partitions on the feed belt into the partition clamping assembly. The partition lifting assembly includes a partition lifting driver and a partition lifting member. The partition lifting member is positioned directly opposite the clamping center of the partition clamping assembly in its normal state. The output end of the partition lifting driver is connected to the partition lifting member to drive the partition lifting member to lift the partition to the clamping center of the partition clamping assembly.

[0013] In some embodiments, the partition feeding device further includes the partition feeding mechanism, which includes a partition inclined feeding bin and a partition pushing assembly for transferring the partitions in the partition inclined feeding bin to the input conveyor belt; one end of the partition inclined feeding bin has an opening, and the partition pushing assembly includes a partition 7-shaped pushing platform and a partition pushing driver. The partition 7-shaped pushing platform is slidably connected to the other end of the partition inclined feeding bin, and the output end of the partition pushing driver is connected to the partition 7-shaped pushing platform. Under normal conditions, the partitions fall from one end of the partition inclined feeding bin into the top surface of the partition 7-shaped pushing platform under the action of gravity. During operation, the partition pushing driver drives the partition 7-shaped pushing platform to slide upward to drive the partitions to be fed, and the partition 7-shaped pushing platform blocks the opening during the sliding process.

[0014] In some embodiments, the partition pusher assembly is configured as three, namely the bottom partition pusher assembly, the middle partition pusher assembly, and the top partition pusher assembly. The outer sides of the middle partition pusher assembly and the top partition pusher assembly are provided with partition "7" shaped fixing platforms. Under normal conditions, the two partition "7" shaped fixing platforms are flush with the partition "7" shaped pusher platforms in the corresponding partition pusher assemblies.

[0015] In some embodiments, an input baffle is provided on the input conveyor belt, and the input baffle and the input conveyor belt form a limiting space for allowing a single partition to pass horizontally.

[0016] In some embodiments, the device further includes a shell feeding device, a lower iron pipe cover feeding device, a lower iron pipe cover assembly device, a pad feeding device, a pad assembly device, a top cover feeding device, and a top cover assembly device. The shell feeding device, the partition feeding device, the lower iron pipe cover feeding device, the pad feeding device, and the top cover feeding device are arranged sequentially at intervals. The lower iron pipe cover feeding device cooperates with the lower iron pipe cover assembly device, the pad feeding device cooperates with the pad assembly device, and the top cover feeding device cooperates with the top cover assembly device to assemble the shell, partition, lower cover, pad, and top cover sequentially.

[0017] In some embodiments, a clamping and transferring device is further included. The clamping and transferring device includes a frame, a transferring and lifting module, a transferring and traversing module, a housing gripper mechanism, a partition gripper mechanism, a lower cover rotating gripper mechanism, a pad gripper mechanism, and an upper cover gripper mechanism. The transferring and lifting module is mounted on the frame. The output end of the transferring and lifting module is connected to the transferring and traversing module. The output end of the transferring and traversing module is connected to the housing gripper mechanism, the partition gripper mechanism, the lower cover rotating gripper mechanism, the pad gripper mechanism, and the upper cover gripper mechanism.

[0018] A method for assembling a three-stage liquid reservoir automatic assembly device is provided, comprising:

[0019] The iron pipe is installed into the lower cover, and the shell, partition, lower cover containing the iron pipe, pad and upper cover are fed at the same time. The partition is conveyed by the input conveyor belt, and the partition with the concave side facing down is screened out by the sieve space formed by the convex sample selection plate connected to the input conveyor belt and the outlet of the inclined slide. The partition with the concave side facing up is conveyed to the feed belt by the inclined slide for feeding.

[0020] The partition is flipped by the flipping assembly. The partition assembly device works so that the concave side of the partition faces the first assembly station. The iron pipe is pressed into the lower cover by the iron pipe lower cover pressing mechanism. Then, the iron pipe lower cover assembly device drives the iron pipe lower cover to face the second assembly station. The pad assembly device drives the pad to face the third assembly station. The upper cover assembly device drives the upper cover to face the fourth assembly station.

[0021] A partition assembly device drives the concave surface of the partition to press against the shell at the first assembly station to form a first assembly. A lower cover assembly device drives the lower cover of the iron pipe to press against the first assembly at the second assembly station. A pad assembly device drives the pad to press against the second assembly at the third assembly station. An upper cover assembly device drives the upper cover to press against the third assembly at the fourth assembly station. Material transfer between the stations is achieved through a clamping and transferring device, and the shell gripper mechanism, partition gripper mechanism, lower cover rotating gripper mechanism, pad gripper mechanism, and upper cover gripper mechanism within the clamping and transferring device simultaneously clamp and move the material.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This application combines an input conveyor belt, a convex sample selection plate, an inclined slide, and a feed belt to form a sieving space between the convex sample selection plate and the inclined slide. When the concave-facing partition passes through the sieving space, due to the continuous resistance of the input conveyor belt at its rear end, the inner surface of the concave-facing partition will contact the protruding part of the convex sample selection plate and fall from the sieving space under the action of thrust, thus screening out the concave-facing partition. When the concave-facing partition passes through, the partition is pushed by the input conveyor belt, and when the partition reaches the protruding part of the convex sample selection plate, it is not interfered with. Therefore, it can be directly conveyed to the inclined slide and continue feeding. Thus, it can be seen that the three-stage automatic assembly equipment for liquid storage tanks of this application can automatically screen the state of the partitions. Partitions with concave surfaces facing downwards cannot pass through due to interference between their concave surfaces and the protruding parts of the convex selection plate, and ultimately fall from the screening space into the collection area below; while partitions with concave surfaces facing upwards can pass through the screening space smoothly and enter the inclined slide for further conveying. This reduces defective products caused by human error during the feeding process, thereby reducing the production cost of the automatic assembly equipment for liquid storage tanks.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0037] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0038] In the following embodiments and accompanying drawings, reference is made to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The coordinate system is defined with the direction of the arrow pointing to the X-axis as right, the direction of the arrow pointing to the Y-axis as front, and the direction of the arrow pointing to the Z-axis as up.

[0039] like Figures 1 to 3 As shown, an automatic assembly device for a three-section liquid reservoir is provided, including: a partition loading device 2; the partition loading device 2 includes a partition conveying mechanism 22, the partition conveying mechanism 22 includes an input conveyor belt 221, a convex sample selection plate 222, an inclined slide 223 and a feed belt 224, the rear end of the inclined slide 223 is connected to the front end of the input conveyor belt 221, and an outlet is provided on the rear end of the inclined slide 223, the convex sample selection plate 222 is connected to the front end of the input conveyor belt 221, and the protruding end of the convex sample selection plate 222 and the side wall of the outlet form a sieve space 225, so that the partition with the concave surface facing down fed by the input conveyor belt 221 falls out of the sieve space 225, and the partition with the concave surface facing up flows through the sieve space 225 and slides into the inclined slide 223.

[0040] Specifically, materials are conveyed from back to front. The input conveyor belt 221 adopts a belt conveyor structure and is horizontally set. Its surface is flat and smooth, facilitating the smooth movement of the partitions. The drive part of the input conveyor belt 221 is driven by a motor. The conveying speed of the partitions can be controlled by adjusting the motor speed. Furthermore, the width of the input conveyor belt 221 is slightly larger than the width of the partitions to ensure that the partitions do not deviate from the conveyor belt during the conveying process. The rear end plane of the inclined slide 223 is higher than the front end plane, forming an inclined surface that is lower at the front and higher at the back. A rectangular outlet is provided at the rear end of the inclined slide 223, and the outlet setting creates a gap between the rear end of the inclined slide 223 and the front end of the input conveyor belt 221. A convex sample selection plate 222 is positioned within the gap, with its straight end connected to the front end of the input conveyor belt 221. The convex end is angled downwards, and is positioned below the inclined surface of the inclined slide 223. The convex sample selection plate 222 maintains a certain distance from the inclined surface of the inclined slide 223, thus forming a sieve space 225 where the concave-faced partition can fall. The sieve space 225 is designed according to the thickness of the partition and the depth of the concave surface, ensuring that only the concave-faced partition can pass smoothly without falling. This partition can slide directly into the lower inclined slide 223. The convex sample selection plate 222 is made of metal with a polished surface to reduce frictional resistance when in contact with the partition. The feed belt 224 is located at the front end of the inclined slide 223, smoothly transitioning to it. It receives the concave-faced partitions from the inclined slide 223 and conveys them to the subsequent workstation. The feed belt 224 is horizontally positioned.

[0041] It is worth noting that this application uses the input conveyor belt 221, the convex sample selection plate 222, the inclined slide 223, and the feed belt 224 to form a sieving space 225 between the convex sample selection plate 222 and the inclined slide 223. When the concave-facing partition passes through the sieving space 225, its rear end is continuously supported by the input conveyor belt 221, causing the inner surface of the concave-facing partition to contact the protruding part of the convex sample selection plate 222 and fall from the sieving space 225 under the action of thrust, thus screening out the concave-facing partition. When the concave-facing partition passes through, it is pushed by the input conveyor belt 221, and when it reaches the protruding part of the convex sample selection plate 222, it is not interfered with, so it can be directly conveyed to the inclined slide 223 and continue feeding. Thus, it can be seen that the three-stage automatic liquid storage tank assembly equipment of this application can automatically screen the state of the partitions. The partitions with the concave side facing down cannot pass through because their concave surface interferes with the protruding part of the convex sample selection plate 222, and eventually fall from the sieving space 225 to the collection area below; while the partitions with the concave side facing up can pass through the sieving space 225 smoothly and enter the inclined slide 223 for further conveying. This reduces defective products caused by human error during the feeding process, thereby reducing the production cost of the automatic liquid storage tank assembly equipment.

[0042] To facilitate the loading of the shell, such as Figure 1 Figure 2 and Figure 4 As shown, in some embodiments, the partition feeding device 2 further includes a partition feeding mechanism 21, which includes a partition inclined feeding bin 211 and a partition pushing assembly 212 for conveying the partitions in the partition inclined feeding bin 211 to the input conveyor belt 221; one end of the partition inclined feeding bin 211 has an opening, and the partition pushing assembly 212 includes a partition 7-shaped pushing platform 2121 and a partition pushing driver. The partition is slidably connected to the other end of the inclined feeding bin 211. The output end of the partition pusher driver is connected to the partition 7-shaped pusher platform 2121. Under normal conditions, the partition falls from one end of the inclined feeding bin 211 into the top surface of the partition 7-shaped pusher platform 2121 under the action of gravity. During operation, the partition pusher driver drives the partition 7-shaped pusher platform 2121 to slide upward to drive the partition to feed material. The partition 7-shaped pusher platform 2121 is also blocked during the sliding process.

[0043] Specifically, in this embodiment, the 7-shaped configuration is mirrored in the figure, specifically a 7-shaped configuration mirrored along the YZ plane. The inclined feed hopper 211 is mounted on the ground via a frame and positioned to the left of the input conveyor belt 221. Both the inclined feed hopper 211 and the 7-shaped pusher platform 2121 are made of stainless steel with smooth inner walls to reduce frictional resistance during movement. The feed hopper's capacity is designed according to production requirements. The feed hopper includes a straight surface and an inclined surface. The straight surface is perpendicular to the horizontal plane, and the inclined surface forms a 30° angle with the horizontal plane. An opening is located at the bottom of the inclined surface. The 7-shaped pusher platform 2121 corresponds to the opening, ensuring that the partition can roll from the inclined surface onto the 7-shaped pusher platform 2121 under gravity. The partition 7-shaped pusher platform 2121 is shaped like the number 7. The short plane supports the partition, while the long plane prevents the remaining partition from falling out of the movable opening. The width of the partition 7-shaped pusher platform 2121 is designed according to the size of the partition to ensure stable support without displacement. The partition pusher driver adopts a cylinder structure, and the stroke length is designed according to the height difference between the partition from the movable opening and the input conveyor belt 221.

[0044] To facilitate material pushing, such as Figure 4 As shown, in some embodiments, three partition pusher assemblies 212 are provided, namely a bottom partition pusher assembly 212, a middle partition pusher assembly 212, and a top partition pusher assembly 212. The outer sides of the middle partition pusher assembly 212 and the top partition pusher assembly 212 are provided with partition 7-shaped fixing platforms 2122. Under normal conditions, the two partition 7-shaped fixing platforms 2122 are flush with the partition 7-shaped pusher platforms 2121 in the corresponding partition pusher assembly 212.

[0045] Specifically, the arrangement of three partition pusher assemblies 212 and two partition 7-shaped fixing platforms 2122 forms a three-stage conveying system, and the three partition pusher assemblies 212 and two partition 7-shaped fixing platforms 2122 are configured to block the movable opening. That is, inside the partition inclined feeding bin 211: a partition pusher assembly 212 is provided at the bottom; a partition 7-shaped fixing platform 2122 and a partition pusher assembly 212 are provided from left to right at the middle; and a partition 7-shaped fixing platform 2122 and a partition pusher assembly 212 are provided from left to right at the top. The bottom partition 7-shaped pusher platform 2121 is slidably connected to the right side of the middle partition 7-shaped fixing platform 2122, the middle partition 7-shaped pusher platform 2121 is slidably connected to the left side of the top partition 7-shaped fixing platform 2122, and the top partition 7-shaped pusher platform 2121 is slidably connected to the straight surface, so as to transfer the partitions on the inclined surface to the input conveyor belt 221 through a three-stage conveying method. Furthermore, the three partition pusher components 212 are driven simultaneously to load materials through a three-stage conveying method. This graded pushing design reduces the stroke and load of a single pusher component, improving the stability and reliability of the system. The three pusher components operate sequentially from bottom to top, ensuring that the partitions can rise smoothly step by step.

[0046] Furthermore, when the partition is conveyed from the inclined feeding bin 211 to the input conveyor belt 221, a pushing component is also provided on the input conveyor belt 221. The pushing component pushes the overlapping partitions on the input conveyor belt 221 back into the inclined feeding bin 211, leaving only a single partition. The pushing component can be configured as a combination of a cylinder and a pusher plate. The height from the bottom surface of the pusher plate to the top surface of the input conveyor belt 221 is slightly greater than the height of a single partition but less than the height of two overlapping partitions, ensuring that only a single partition remains on the input conveyor belt 221.

[0047] To facilitate material feeding, such as Figure 2 As shown, in some embodiments, an input baffle 2211 is provided on the input conveyor belt 221, and the input baffle 2211 and the input conveyor belt 221 form a limiting space for allowing a single partition to pass horizontally.

[0048] Specifically, an input baffle 2211 is provided on the right side of the input conveyor belt 221. A limiting space is formed between the input baffle 2211 and the input conveyor belt 221 to allow a single partition to pass horizontally. The distance between the input baffle 2211 and the input conveyor belt 221 is slightly greater than the thickness of the partition, allowing the partition to pass smoothly without getting stuck. Furthermore, the input baffle 2211 can cooperate with the pusher assembly to ensure that a single partition remains on the input conveyor belt 221.

[0049] To facilitate the assembly of the partitions, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the partition loading device 2 further includes a flipping mechanism 23, which is mounted on the feeding belt 224 to flip the partitions on the feeding belt 224; the three-section liquid storage automatic assembly equipment also includes a partition assembly device 6, which includes a partition positioning mechanism 61 and a partition pressing mechanism 62. The partition positioning mechanism 61 includes a partition translation module 614, a partition clamping assembly 611 for clamping the partitions conveyed by the feeding belt 224, and a partition rotation driver 612 for driving the partition clamping assembly 611 to rotate. The output end of the partition translation module 614 is connected to the partition rotation driver 612, and the output end of the partition rotation driver 612 is connected to the partition clamping assembly 611 to cooperate with the flipping mechanism 23 so that the concave surface of the partition is aligned with the housing during processing; the working end of the partition pressing mechanism 62 presses the partition on the partition clamping assembly 611 against the housing.

[0050] Specifically, refer to Figure 2 The flipping mechanism 23 is mounted on the feed belt 224 to flip the partition so that its concave surface faces downwards. (Reference) Figure 1 , Figure 5 and Figure 6 The partition assembly device 6 also includes a frame, which is U-shaped, and the feed belt 224 passes through the frame to convey the partitions. A partition translation module 614 is mounted on the frame and uses a linear guide rail structure, driven by a servo motor, to achieve precise horizontal movement of the partitions. The partition rotation driver 612 uses a servo motor structure to achieve precise rotation of the partition clamping assembly 611, causing the concave-facing partition to rotate 90°, so that the concave surface of the partition faces forward. The partition clamping assembly 611 uses a pneumatic gripper structure with rubber pads to firmly clamp the partitions without damaging their surfaces. The partition pressing mechanism 62 includes a pressing driver and a pressing component. The partition pressing driver is mounted on the frame via a mounting platform. The output end of the partition pressing driver is connected to the partition pressing component to drive the partition pressing component to horizontally press the partition on the partition clamping assembly 611 onto the housing for assembly. Furthermore, the partition pressing driver can be configured as a cylinder, and the partition pressing component can be configured as a partition pressing column.

[0051] To facilitate the use of the material turning mechanism 23, such as Figure 2 As shown, in some embodiments, the material turning mechanism 23 includes a material turning driver 231 and a rotating shaft 232. The material turning driver 231 is mounted on the feed belt 224, and the output end of the material turning driver 231 is connected to the rotating shaft 232 to drive the rotating shaft 232 to rotate on the feed belt 224. A magnetic part is provided on the rotating shaft 232 so that the partition can be turned over on the feed belt 224 by the rotation of the magnetic part.

[0052] Specifically, the flipping driver 231 is installed on the left side of the feed belt 224. The flipping driver 231 employs a stepper motor structure, enabling precise control of the rotating shaft 232. The rotating shaft 232 is made of stainless steel. Mounting plates are installed on both sides of the feed belt 224, and these plates are bolted to the support of the feed belt 224. Rotation holes are provided on the mounting plates, and both ends of the rotating shaft 232 are connected to these rotation holes via bearings, ensuring smooth rotation of the rotating shaft 232. The magnetic component uses a powerful permanent magnet embedded in the surface of the rotating shaft 232. The magnetic strength is designed according to the weight of the partition, ensuring it can attract the partition and cause it to flip.

[0053] In order to transfer the partition from the feed belt 224 to the partition clamping assembly 611, such as Figure 5 and Figure 6 As shown, in some embodiments, the partition positioning mechanism 61 further includes a partition lifting assembly 613 that lifts the partitions on the feed belt 224 into the partition clamping assembly 611. The partition lifting assembly 613 includes a partition lifting driver 6131 and a partition lifting member 6132. The partition lifting member 6132 is positioned directly opposite the clamping center of the partition clamping assembly 611 under normal conditions. The output end of the partition lifting driver 6131 is connected to the partition lifting member 6132 to drive the partition lifting member 6132 to lift the partition to the clamping center of the partition clamping assembly 611.

[0054] Specifically, the partitions on the feed belt 224 can be transferred to the partition lifting component 6132 via grippers; alternatively, the front end of the feed belt 224 can be positioned at the partition positioning mechanism 61 to directly transmit the partitions to the clamping center of the partition lifting assembly 613 within the partition positioning mechanism 61. The partition lifting driver 6131 adopts a cylinder structure. The partition lifting component 6132 is configured as a partition lifting platform, with its center directly opposite the clamping center of the normally functioning partition clamping assembly 611. The size of the partition lifting platform is slightly smaller than the size of the partition to ensure stable support of the partition without displacement. The upper surface of the partition lifting platform has positioning protrusions that engage with the concave surface of the partition to ensure accurate positioning of the partition during the lifting process.

[0055] To facilitate the automatic assembly of the liquid reservoir, such as Figure 1As shown, in some embodiments, the three-section liquid reservoir automatic assembly equipment further includes a shell feeding device 1, an iron pipe lower cover feeding device 3, an iron pipe lower cover assembly device 7, a pad feeding device 4, a pad assembly device 8, an upper cover feeding device 5, and an upper cover assembly device 9. The shell feeding device 1, the partition plate feeding device 2, the iron pipe lower cover feeding device 3, the pad plate feeding device 4, and the upper cover feeding device 5 are arranged sequentially at intervals. The iron pipe lower cover feeding device 3 cooperates with the iron pipe lower cover assembly device 7, the pad plate feeding device 4 cooperates with the pad plate assembly device 8, and the upper cover feeding device 5 cooperates with the upper cover assembly device 9 to assemble the shell, partition plate, lower cover, pad plate, and upper cover in sequence.

[0056] Specifically, the shell feeding device 1, partition plate feeding device 2, iron pipe lower cover feeding device 3, pad plate feeding device 4, and upper cover feeding device 5 are arranged alternately from left to right. The partition plate assembly device 6, iron pipe lower cover assembly device 7, pad plate assembly device 8, and upper cover assembly device 9 are also arranged alternately from left to right. Each assembly device and each feeding device is arranged in a one-to-one correspondence, and each assembly device is located in front of its respective feeding device, forming a processing line for a single component other than the shell. Each line is responsible for the feeding and assembly of one component.

[0068] To facilitate the automatic assembly of the liquid reservoir, such as Figure 1 , Figure 7 and Figure 8 As shown, in some embodiments, the three-section liquid reservoir automatic assembly equipment further includes a clamping and transferring device 10. The clamping and transferring device 10 includes a frame 101, a transferring and lifting module 102, a transferring and traversing module 103, a shell gripper mechanism 104, a partition gripper mechanism 105, a lower cover rotating gripper mechanism 106, a pad gripper mechanism 107, and an upper cover gripper mechanism 108. The transferring and lifting module 102 is mounted on the frame 101. The output end of the transferring and lifting module 102 is connected to the transferring and traversing module 103. The output end of the transferring and traversing module 103 is connected to the shell gripper mechanism 104, the partition gripper mechanism 105, the lower cover rotating gripper mechanism 106, the pad gripper mechanism 107, and the upper cover gripper mechanism 108.

[0069] Specifically, the frame 101 is positioned in front of each assembly device. The frame 101 is constructed of aluminum profiles, possessing high strength and good stability, capable of withstanding the weight and reaction forces generated by the movements of various gripper mechanisms. The height of the frame 101 is designed according to the height of each workstation, ensuring that the clamping and transferring device 10 can cover all workstations. The material transfer lifting module 102 employs a servo motor-driven screw-slider structure to achieve precise vertical movement of the gripper mechanism. The stroke length of the lifting module is designed according to the height difference between each workstation. The material transfer traverse module 103 employs a servo motor-driven synchronous belt structure to achieve precise horizontal movement of the gripper mechanism. The stroke length of the traverse module is designed according to the distance between each workstation. The housing gripper mechanism 104, partition gripper mechanism 105, iron pipe lower cover rotating gripper mechanism 106, pad gripper mechanism 107, and upper cover gripper mechanism 108 are arranged sequentially from left to right and connected to the transverse moving module. All four mechanisms operate simultaneously. The housing gripper mechanism 104 employs a pneumatic gripper structure with specially designed clamping blocks, enabling it to firmly grip the housing without damaging its surface. The opening and closing distance of the grippers is designed according to the dimensions of the housing. The partition gripper mechanism 105 employs a pneumatic gripper structure with rubber pads, enabling it to firmly grip the partition without damaging its surface. The opening and closing distance of the grippers is designed according to the thickness of the partition. The iron pipe lower cover rotating gripper mechanism 106 includes a pneumatic gripper and a rotary cylinder 1061, equipped with a specially designed clamping block, which can firmly grip the lower cover with the iron pipe. The output end of the rotary cylinder 1061 is connected to the pneumatic gripper, enabling 180° rotation of the gripped material, allowing the two ends of the housing to interchange positions. The pad gripper mechanism 107 adopts a pneumatic gripper structure, equipped with a specially designed clamping block, which can accurately place it at the assembly station. The upper cover gripper mechanism 108 adopts a pneumatic gripper structure, equipped with a specially designed clamping block, which can firmly grip the upper cover without damaging the surface of the upper cover. The opening and closing distance of the gripper is designed according to the size of the upper cover, and the clamping force is adjusted by air pressure.

[0070] And, as Figure 6 , Figure 8 and Figure 9 Below the housing gripper mechanism 104 is a housing transfer station a; below the partition gripper mechanism 105 is a first assembly station b; below the iron pipe lower cover rotating gripper mechanism 106 is a second assembly station c; below the pad gripper mechanism 107 is a third assembly station d; and below the upper cover gripper mechanism 108 is a fourth assembly station e. Each station is configured as a clamping and positioning structure for fixed processing.

[0071] Thus, for reference Figure 6 , Figure 8 and Figure 9The production process of a single three-section liquid reservoir is as follows: First, the shell has a first end and a second end that are arranged opposite to each other. The shell is transferred from the shell transfer station a to the first assembly station b via the shell gripper mechanism 104 of the clamping and transferring device 10. At the first assembly station b, the first end of the shell is pressed against the concave surface of the partition to obtain the first assembly. Then, the first assembly is transferred to the second assembly station c via the partition gripper mechanism 105 of the clamping and transferring device 10, so that the first assembly is pressed against the lower cover of the iron pipe to obtain the second assembly. The second assembly is then transferred to the lower cover of the iron pipe via the clamping and transferring device 10. The cover rotation gripper mechanism 106 transfers the second assembly to the third assembly station d, and drives the second assembly to rotate 180° so that the second end of the shell is aligned with the pad. The second assembly is pressed against the pad to obtain the third assembly. The third assembly is transferred to the fourth assembly station e by the pad gripper mechanism 107 of the clamping and transferring device 10, so that the third assembly is pressed against the cover. After pressing, a primary product is obtained. The primary product is then moved to the recycling station by the cover gripper mechanism 108 of the clamping and transferring device 10. Finally, it is transported to the welding station f by the conveyor belt for welding to obtain the formed product.

[0072] The overall working steps of the three-stage liquid storage automatic assembly equipment are as follows:

[0073] First, such as Figure 1 , Figure 7 and Figure 9 As shown, each workstation prepares materials:

[0074] Multiple shells are manually poured into the inclined shell feeding hopper. Under gravity, the shells reach the bottom shell 7-shaped pusher platform. The shell feeding device 1 is activated, and the bottom shell pusher driver moves the bottom shell 7-shaped pusher platform upwards, aligning it with the middle shell 7-shaped fixed platform. Some shells can then reach the middle shell 7-shaped fixed platform. Simultaneously, the middle shell pusher driver moves the middle shell 7-shaped pusher platform upwards, allowing the middle shells to reach the fixed platform. The U-shaped pusher platform is flush with the top housing 7-shaped fixed platform, allowing some housings to reach the top housing 7-shaped fixed platform. Simultaneously, the top housing pusher driver drives the top housing 7-shaped pusher platform to move upward, making it flush with the housing conveyor belt, allowing the housings to reach the housing conveyor belt. This process is repeated, with three housing pusher components simultaneously conveying the housings from the bottom of the inclined loading bin to the housing conveyor belt, which then conveys the housings from back to front.

[0075] refer to Figures 1 to 4Multiple partitions are manually poured into the inclined feeding hopper 211. Under gravity, the partitions reach the bottom partition 7-shaped pusher platform 2121. The partition feeding device is activated, and the bottom partition pusher driver drives the bottom partition 7-shaped pusher platform 2121 to move upward, making it flush with the middle partition 7-shaped fixed platform 2122. Some partitions can reach the middle partition 7-shaped fixed platform 2122. At the same time, the middle partition pusher driver drives the middle partition 7-shaped pusher platform 2121 to move upward, thus allowing the middle partition 7-shaped pusher platform 2121 to move upward. 21 is flush with the top partition 7-shaped fixing platform 2122, and part of the partition can reach the top partition 7-shaped fixing platform 2122; at the same time, the top partition pusher drive drives the top partition 7-shaped pusher platform 2121 to move upward, so that the top partition 7-shaped pusher platform 2121 is flush with the input conveyor belt 221, and the partition can reach the input conveyor belt 221. This process is repeated, and the three partition pusher components 212 convey the partitions at the bottom of the partition inclined feeding bin 211 to the input conveyor belt 221. The input conveyor belt 221 conveys the partitions from back to front. After being limited by the pushing assembly and the input baffle 2211, the partition remains in a single state on the input conveyor belt 221. The input conveyor belt 221 continues to transport the partitions and reaches the sieving space 225 to screen out the partitions with their concave surfaces facing down, retaining the partitions with their concave surfaces facing up. The partitions then travel from the inclined slide 223 to the feed belt 224 and are flipped by the magnetic part of the flipping mechanism 23, so that the concave surfaces of the partitions face down. Figure 5 and Figure 6 And it is understandable that, Figure 6 The partition clamping assembly 611 is in the state after being rotated 90°. The partition clamping assembly 611 in the normal state is as follows: Figure 5 As shown, it is laid flat along the XY plane to receive the partition on the partition lifting member 6132. The partition continues to be conveyed until it reaches the partition lifting member 6132. The partition lifting member 6132 is driven to lift by the partition lifting driver 6131, so that the partition reaches the center of the horizontally placed partition clamping assembly 611. The partition clamping assembly 611 clamps the partition, and then the partition rotation driver 612 drives the partition clamping assembly 611 to rotate 90°, so that the concave surface of the partition faces the first assembly station b.

[0076] The iron pipe is manually inserted into the lower cover and conveyed via the lower cover conveyor chain. Upon reaching the front end of the conveyor chain, the lower cover translation clamping assembly clamps the lower cover and guides it to the lower cover fixing assembly. The fixing assembly then tightens the lower cover, and the lower cover pressing assembly presses it down, fixing the iron pipe to the lower cover. The fixing assembly then releases, and the lower cover translation clamping assembly continues to hold the lower cover onto the iron pipe. On the lower cover conveyor chain, the iron pipe lower cover continues to be transported until the iron pipe lower cover reaches the iron pipe lower cover lifting component. The iron pipe lower cover lifting component is driven by the iron pipe lower cover lifting driver to lift the iron pipe lower cover, so that the iron pipe lower cover reaches the center of the horizontally placed iron pipe lower cover clamping assembly. The iron pipe lower cover clamping assembly clamps the iron pipe lower cover. Then, the iron pipe lower cover rotation driver drives the iron pipe lower cover clamping assembly to rotate 90°, so that the assembly surface of the iron pipe lower cover faces the second assembly station c.

[0077] Multiple pads are manually placed on the pad conveyor belt, which transports them one by one. The pad limit adjustment component adjusts the pads to ensure that they are transported until they reach the pad lifting component. The pad lifting driver drives the pad lifting component to lift the pads, so that the pads reach the center of the horizontally placed pad clamping component. The pad clamping component clamps the pads, and then the pad rotation driver drives the pad clamping component to rotate 90°, so that the pads face the third assembly station d.

[0078] Multiple covers are manually placed on the cover conveyor belt, which transports them one by one. The cover limit adjustment component adjusts the conveyor belt to ensure that the covers are transported until they reach the cover lifting component. The cover lifting driver drives the cover lifting component to lift the cover, so that the cover reaches the center of the horizontally placed cover clamping component. The cover clamping component clamps the cover, and then the cover rotation driver drives the cover clamping component to rotate 90° so that the assembly surface of the cover faces the third assembly station d.

[0079] Subsequently, with corresponding materials available at each workstation, each component is processed simultaneously:

[0080] The partition translation module 614 drives the partition clamping assembly 611 to move the partition to the first assembly station b. At the same time, the partition pressing driver drives the partition pressing component to press the partition horizontally, pressing the partition on the partition clamping assembly 611 into the housing on the first assembly station b, so that the concave surface of the partition is pressed with the housing on the first assembly station b to form the first assembly.

[0081] The iron pipe lower cover translation module drives the iron pipe lower cover clamping assembly to move the iron pipe lower cover to the second assembly station c. At the same time, the iron pipe lower cover pressing driver drives the iron pipe lower cover pressing component to press the iron pipe lower cover horizontally, pressing the iron pipe lower cover on the iron pipe lower cover clamping assembly into the first assembly body on the second assembly station c to form the second assembly body.

[0082] The pad plate clamping assembly is driven by the pad plate translation module to move the pad plate to the third assembly station d. At the same time, the pad plate pressing driver drives the pad plate pressing component to press the pad plate horizontally and press the pad plate into the second assembly body on the third assembly station d to form the third assembly body.

[0083] The upper cover is driven by the upper cover translation module to hold the upper cover, which moves the upper cover to the fourth assembly station e. At the same time, the upper cover pressing driver drives the upper cover pressing component to press the upper cover horizontally, pressing the upper cover into the third assembly body on the fourth assembly station e to form a primary product.

[0084] Finally, the individual primary products are welded together in sequence to obtain the final product.

[0085] The material transfer between each station is achieved synchronously through the clamping and transferring device 10. The shell gripper mechanism 104 reciprocates between the shell transfer station a and the first assembly station b. The partition gripper mechanism 105 reciprocates between the first assembly station b and the second assembly station c. The iron pipe cover rotating gripper mechanism 106 reciprocates between the second assembly station c and the third assembly station d. The iron pipe cover rotating gripper drives the third assembly to rotate 180° so that the shell after conversion can be assembled in the next step. The pad gripper mechanism 107 reciprocates between the third assembly station d and the fourth assembly station e. The upper cover gripper mechanism 108 reciprocates between the fourth assembly station e and the recycling station.

[0086] In addition, such as Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, reinforcing plates can also be placed in the liquid reservoir. The three-section liquid reservoir automatic assembly equipment of this application can also include a reinforcing plate loading device 31 and a reinforcing plate assembly device 71, and a reinforcing plate assembly station g is also provided. The clamping and transferring device 10 also includes a reinforcing plate gripper mechanism 109, which is connected to the output end of the transferring transverse module 103. The reinforcing plate loading device 31 includes a reinforcing plate conveying mechanism, which includes a reinforcing plate conveyor belt. The reinforcing plate conveyor belt can transport multiple reinforcing plates, and a reinforcing plate limit adjustment component is provided at the middle end of the reinforcing plate conveyor belt. The reinforcing plate limit adjustment component includes a reinforcing plate limit driver and a reinforcing plate guide block. The reinforcing plate limit driver is set on the reinforcing plate conveyor belt, and the output end of the reinforcing plate limit driver is connected to the reinforcing plate guide block to push multiple reinforcing plates to be transferred one by one on the reinforcing plate conveyor belt. The reinforcing plate assembly device 71 includes a reinforcing plate positioning mechanism and a reinforcing plate pressing mechanism. The reinforcing plate positioning mechanism and the partition plate positioning mechanism 61 have similar component structures and mating methods; the reinforcing plate pressing mechanism and the partition plate pressing mechanism 62 have similar component structures and mating methods. The front end of the reinforcing plate conveyor belt is arranged adjacent to the reinforcing plate positioning mechanism to transport the reinforcing plate to the clamping center of the reinforcing plate lifting assembly within the reinforcing plate positioning mechanism.

[0087] Furthermore, in any of the above embodiments, each relevant component is equipped with a positioning sensing component. Processing only begins after each component detects its positioning, ensuring the smooth operation of each process. Additionally, during feeding, the conveying component is equipped with a material control structure. The material control component controls the conveying progress, ensuring that the conveying component only transports the next material after the previous material has been processed. It should be noted that the specific components of the three-stage liquid storage tank automatic assembly equipment described above all utilize existing components, such as the transverse module, lifting module, motor, cylinder, clamping components, pneumatic grippers, and conveyor belt, which will not be described in detail in this solution.

[0088] It can be seen that the structures of the various devices in this application can work synchronously, and the clamping and transferring device 10 cooperates with the processing devices at each station to perform synchronous material transfer and processing, thereby effectively shortening the processing time and speeding up the processing efficiency. In addition, almost all loading stations are equipped with large loading spaces, thereby effectively reducing manual intervention and thus effectively increasing the automation level of the three-stage liquid storage automatic assembly equipment.

[0089] An assembly method for a three-stage liquid reservoir automatic assembly device is provided, including the following steps:

[0090] S110, the iron pipe is installed into the lower cover, and the housing, partition, lower cover containing the iron pipe, pad, and upper cover are fed simultaneously. The partition is conveyed by the input conveyor belt, and the partition with the concave side facing down is screened out by the sieve space formed by the convex selection plate connected to the input conveyor belt and the outlet of the inclined slide. The partition with the concave side facing up is conveyed to the feed belt by the inclined slide for feeding.

[0091] Specifically, the shell, partition, lower cover with iron pipe, pad, and upper cover are fed simultaneously to transport each material to the preparation area.

[0092] S120, the partition is flipped by the flipping component, and the partition assembly device works so that the concave surface of the partition faces the first assembly station. The iron pipe is pressed into the lower cover by the iron pipe lower cover pressing mechanism, and then the iron pipe lower cover assembly device drives the iron pipe lower cover to the second assembly station. The pad assembly device drives the pad to the third assembly station, and the upper cover assembly device drives the upper cover to the fourth assembly station.

[0093] Specifically, by preparing materials for each component, each component is transported to its corresponding workstation.

[0094] S130, the partition assembly device drives the concave surface of the partition to press against the shell at the first assembly station to form a first assembly. The iron pipe lower cover assembly device drives the iron pipe lower cover to press against the first assembly at the second assembly station. The pad assembly device drives the pad to press against the second assembly at the third assembly station. The upper cover assembly device drives the upper cover to press against the third assembly at the fourth assembly station. Material transfer between the stations is achieved through a clamping and transferring device, and the shell gripper mechanism, partition gripper mechanism, iron pipe lower cover rotating gripper mechanism, pad gripper mechanism, and upper cover gripper mechanism within the clamping and transferring device simultaneously clamp and move the material.

[0095] Specifically, the shell gripper mechanism, partition gripper mechanism, iron pipe lower cover rotating gripper mechanism, pad gripper mechanism, and upper cover gripper mechanism move up and down and laterally in sync to transfer the corresponding materials. After each component is processed at its corresponding workstation and pressed together, all parts of the three-section liquid reservoir are firmly connected together. Subsequent welding will then form a complete primary product.

[0096] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.
