Description

Technical Field

[0001] This application belongs to the field of air conditioning liquid receiver manufacturing, and particularly relates to an automatic vertical spinning production line and manufacturing method for air conditioning liquid receivers. Background Technology

[0002] In the field of refrigeration and air conditioning systems, the compressor is the core component, and its stable operation directly affects whether the entire system can work efficiently and reliably. The receiver-of-charge (ROC), as an important auxiliary component of the compressor, plays an indispensable role in the refrigeration system. Its main function is to store liquid refrigerant, effectively preventing the compressor from operating in unstable conditions, thereby ensuring the normal operation of the refrigeration system.

[0003] Currently, the raw materials for producing liquid storage tanks are cylindrical bodies of equal length with open ends, cut from metal tubes. The processing involves multiple steps. First, a spinning machine is used to spin-form a closed-end structure at one end of the cylindrical body. Next, a tube flaring and polishing machine is used to flare the other end of the body, increasing the opening size to facilitate the installation of subsequent components. After flaring, the inside of the body is cleaned to remove metal shavings, dust, and other impurities generated during processing. Then, a CNC press-fitting machine is used to press-fit the baffles and filters into the inside of the body. The other end of the body is then spun closed using a spinning machine. Finally, a tube-loading machine is used to install the end gas pipes.

[0004] However, the existing liquid storage tank processing flow has many problems that urgently need to be solved:

[0005] Low efficiency in process transfer: Some processes still heavily rely on workers for inter-process transfers. Manual transfers not only consume a significant amount of time and energy, but are also prone to waiting and delays during the transfer process. This not only prolongs the entire processing cycle but also makes it difficult to effectively improve production efficiency and meet the ever-increasing market demand.

[0006] Metal pipe surface contamination: Since metal pipes inevitably have some rust and dirt on their surface, these impurities can contaminate the processing equipment if they are directly put into processing. For example, during the spinning process, rust may fall into the spinning machine, which may not only cause downtime and affect the continuity of production, but also contaminate the work area, increasing subsequent cleaning costs and difficulties.

[0007] Fluctuations in metal tube material quality affect product quality: The material properties of the metal tubes can vary, meaning the purchased tubes may possess different characteristics, some with higher hardness and others with lower softness. During the spinning process, these material differences can lead to subtle, barely perceptible taper changes after spinning and finishing. These changes are not easily detected during production and can only be identified through subsequent inspection. However, by this time, the product is often already deemed defective and must be scrapped, resulting in wasted raw materials and increased production costs. Therefore, existing technology requires further improvement and enhancement. Summary of the Invention

[0008] This invention provides an automatic vertical spinning production line and production method for air conditioner liquid receivers, which at least solves or alleviates one or more technical problems in the prior art, or at least provides a beneficial alternative.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] An automatic vertical spinning production line for air conditioning liquid receivers includes a first vertical spinning machine, a tube expanding and polishing machine, a pressing machine, a second vertical spinning machine, and a tube loading machine arranged sequentially in the x-axis direction.

[0011] A conveying device is installed on one side of the first vertical spinning machine and the second vertical spinning machine, including a conveyor line that conveys along the x-axis and multiple gantry frames that cross the conveyor line; each gantry frame is provided with a gripper assembly that can be lifted, moved along the y-axis and rotated, the gripper assembly being used to send the cylinder to be processed to the inlet of the vertical spinning machine and to remove the spun cylinder from the inlet of the vertical spinning machine;

[0012] The transfer device is installed on the table of the pipe expanding and polishing machine, the pressing machine, and the pipe loading machine, and includes parallel gripper units; each gripper unit can independently grip and release the cylinder, and the spacing between adjacent gripper units is fixed; the parallel gripper units can reciprocate along the x-axis to achieve continuous equidistant movement of the cylinder;

[0013] The loading station is located on the table of the pipe expanding and polishing machine, the pressing machine, and the pipe loading machine. The loading station is equipped with a positioning component and a detection component. The positioning component is located at the intersection of the path range that the gripper assembly can cover when moving along the y-axis and the path range that the gripper unit can cover when moving along the x-axis, and is used to position and temporarily store the cylinder. The detection component is used to detect whether there is material at the loading station and transmits the detection signal to the controller. The controller controls whether the gripper assembly or gripper unit of the next process can move to transfer the cylinder to each station for processing according to the detection signal, so as to realize fully automatic continuous production.

[0014] In a preferred implementation, the conveyor line includes a loading bus, a unloading bus, and loading sub-lines. The loading bus and unloading bus correspond to multiple parallel first vertical spinning machines or second vertical spinning machines. Each vertical spinning machine has two spinning inlets corresponding to two loading sub-lines and corresponding to a first gantry frame, a second gantry frame, and a third gantry frame. The gripper assembly of the first gantry frame transfers the cylinder to be processed on the loading bus to the two secondary loading sub-lines. The gripper assemblies on the second and third gantry frames respectively send the cylinder to be processed on the two loading sub-lines to the spinning inlets and respectively transfer the spun cylinder to the unloading bus.

[0015] In a preferred embodiment, a cleaning device is also included, which is located in front of the first vertical spinning machine. The cleaning cylinder is fed onto the feeding bus via the gripper assembly on the fourth portal frame. The cylinder on the unloading bus is automatically unloaded to the loading station of the tube expander and polisher / tube packer via the gripper assembly on the fifth portal frame.

[0016] In a preferred implementation, the gripper assembly is equipped with a pipe-clamping cylinder on the front side of the pickup position corresponding to the loading bus, loading sub-line and unloading bus, and a material stopper is provided on the rear side. A sensor for sensing whether there is material is provided between the pipe-clamping cylinder and the material stopper. A safety light curtain is provided at the placement position of the gripper assembly corresponding to the unloading bus.

[0017] In a preferred embodiment, the first vertical spinning machine / second vertical spinning machine is equipped with a slide table that can move along the y-axis. The slide table has a loading position and a unloading position. The gripper assemblies on the second and third portal frames respectively send the cylinders to be processed from the two loading lines to the loading position or remove them from the unloading position. The loading position is equipped with a first sensor to sense whether there is material and transmit the information to the controller. The controller controls the slide table to move to the spinning position corresponding to the loading position. The unloading position is equipped with a second sensor to sense whether there is material and transmit the information to the controller. The controller controls the gripper assembly to move to the unloading position to pick up the processed cylinder.

[0018] In a preferred embodiment, the transfer device includes two slide rails on the table of the pipe expanding and polishing machine / pressing machine / pipe loading machine and a slider that cooperates with the slide rails. A rack is provided between the two slide rails. An L-shaped support plate is provided on the upper side of the slider. A drive motor is provided on the part of the support plate parallel to the slide rails. The output shaft of the drive motor is provided with a gear that meshes with the rack. A gripper mounting frame is slidably connected to the part of the support plate perpendicular to the slide rails. The gripper mounting frame is connected to a lifting mechanism. The gripper unit is mounted on the gripper mounting frame.

[0019] In a preferred implementation, the pipe expanding and polishing machine has a pipe expanding station and an inner wall polishing station. The positioning component of the loading station on the table of the pipe expanding and polishing machine is cylindrical. The diameter of the end of the cylindrical component is adapted to the inner diameter of the cylinder, and the lower side is larger than the outer diameter of the cylinder. The gripper unit is provided with three grippers with a spacing adapted to the pipe expanding station and the inner wall polishing station. The gripper unit located at the end is connected to a flipping motor to realize the flipping of the cylinder.

[0020] In a preferred implementation, the press-fitting machine has a first partition pre-assembly station, a first partition press-fitting and grooving station, a second partition pre-assembly station, a second partition press-fitting and grooving station, a filter pre-assembly station, and a filter press-fitting and grooving station. The gripper unit has seven grippers with a spacing adapted to the distance between each station. On one side of the filter press-fitting and grooving station, there is also a material unloading station that is opposite to the material loading station.

[0021] In a preferred embodiment, the tube loading machine has a first foreign object suction station, a flux storage liquid cup station, a second foreign object suction station, an inner tube pre-assembly station, and an inner tube pressing station. The gripper unit has five grippers with a spacing adapted to the distance between each station, and the positioning element is located on the upper side of the first foreign object suction station.

[0022] In a preferred embodiment, the positioning parts of the press machine table and the pipe fitting machine table have cylindrical grooves at their ends, and the inner diameter of the cylindrical grooves is adapted to the outer diameter of the cylinder.

[0023] The production method of the automatic vertical spinning production line for air conditioner liquid receivers includes the following steps:

[0024] S1: Cylinder cleaning and rust removal

[0025] The cut cylinder is placed vertically and passed through the cleaning device. The cleaning components inside the device perform rust removal and cleaning on the outer surface of the cylinder, removing iron oxide rust and dirt, ensuring the cleanliness of the cylinder surface, and providing a good foundation for subsequent processing.

[0026] S2: Preparation for cylinder loading bus allocation

[0027] After the cleaned cylinder comes out of the cleaning device and reaches the designed position, the sensing element set at the position detects the cylinder. Then, the gripper assembly on the fourth gantry frame picks up the cylinder, flips it 90 degrees, and places it horizontally on the loading bus.

[0028] S3: The feeding bus provides balanced material supply for the spinning machine.

[0029] Cylinders continuously fed along the feeding bus at designed intervals arrive at the pick-up position of the first vertical spinning machine. After the sensing element detects the cylinder at this position, the clamping cylinder and the blocking element activate to ensure that there is only one cylinder at the pick-up position. The gripper assembly on the first gantry frame picks up at least two cylinders in a row and distributes them to the two feeding lines. Then, the corresponding clamping cylinder and blocking element stop working, and the cylinder continues to move along the feeding bus to the pick-up position of the second first vertical spinning machine. Similarly, after at least two cylinders are placed, the clamping cylinder and blocking element at the previous position resume working. This process is repeated to distribute the same number of cylinders to the two first vertical spinning machines.

[0030] S4: Preparation for feeding the feeding section cylinder

[0031] The cylinder to be processed at the feeding line moves to the picking position of the line. After the sensor detects the cylinder, the clamping cylinder and the baffle start to work. The gripper assembly on the second and third portal frames picks up the cylinder, rotates it 90 degrees, and places it vertically on the feeding position of the first / second spinning machine slide.

[0032] S5: Spinning and finishing operation on a spinning machine

[0033] After the sensor on the loading position detects the cylinder, the slide moves along the y-axis to the spinning position. The spinning mechanism at the spinning position descends and installs the cylinder from the loading position onto the mold. Then the slide retracts and begins the spinning and closing operation. After the slide retracts, a new cylinder is simultaneously placed into the loading position. At this time, it is necessary to wait for the previous cylinder to complete the spinning. After the spinning is completed, the slide re-enters, first aligning the unloading position with the spinning position to receive the spun cylinder. Then the slide continues to move forward to the spinning position corresponding to the loading position to install the new cylinder. Finally, the slide retracts.

[0034] S6: Spinning completed cylinder unloading and temporary storage

[0035] After the sensor at the unloading position detects the presence of material, the gripper assemblies on the second and third portal frames pick up and remove the cylinder after one end has been spun, and place it into the unloading bus. The safety light curtain at the placement position senses whether there is material. If there is material, the gripper assembly will not release the material temporarily to ensure that the cylinder is placed in an orderly manner.

[0036] S7: The cylinder is transferred to the tube expander and polishing machine.

[0037] As the cylinder moves to the end along the feeding bus, the sensing element detects the presence of material, and the clamping cylinder and the material blocking element are activated. Then, the gripper assembly on the fifth portal frame picks up the cylinder and flips it over, sending it to the feeding station of the tube expander and polisher, so that the un-spun end is placed facing down on the outside of the cylindrical end.

[0038] S8: Pipe Expanding and Polishing Machine Processing

[0039] After the inspection unit detects that there is material at the loading station of the tube expanding and polishing machine, the moving device is activated. The gripper unit first grips the cylinder, then lifts, moves horizontally, and lowers it to the tube expanding station for the tube expanding process. After expansion, the opening side of the tube is funnel-shaped. Next, the second gripper unit grips the cylinder, lifts, moves horizontally, and lowers it to the inner wall polishing station for inner wall polishing. Then, the third gripper unit grips the cylinder, lifts, moves horizontally, and flips it, placing the cylinder with the expanded hole side facing up at the loading station of the pressing machine.

[0040] S9: Press-fitting machine assembly operation

[0041] With the expanded hole side of the cylinder facing upwards and the closed side located in the cylindrical groove of the positioning component, after the detection component detects the presence of material, the transfer device on the tube loading machine begins to deliver material in the same way as the transfer device in S8, completing the assembly of the partition and filter, and sending the assembled cylinder to the unloading station.

[0042] S10: Second vertical spinning machine for secondary spinning

[0043] After completing the above process, the cylinder passes through the conveyor line of the second vertical spinning machine and repeats steps S6-S7 to achieve the other end of the cylinder being spun and closed.

[0044] S11: Final processing by the pipe-loading machine

[0045] The cylinder with both ends closed is placed at the loading station of the tube loading machine. The loading station is the same location as the first foreign object dust collection station. The cylinder is delivered sequentially by the transfer device to each station for processing, thus completing the processing flow of the entire production line.

[0046] The above structure has the following beneficial effects:

[0047] 1. The automatic vertical spinning production line for air conditioning liquid receivers of this application has each processing equipment arranged sequentially along the x-axis, and together with the conveying device and the transfer device, a continuous production process is formed. The entire production line realizes the fully automatic transfer of the cylinder between each process, without the need for workers to perform heavy transfer work.

[0048] 2. The automatic vertical spinning production line for air conditioning liquid receivers of this application includes a feeding bus, a discharging bus, and a feeding sub-line. The feeding bus and the discharging bus correspond to multiple parallel first or second vertical spinning machines. This layout makes full use of space, reduces the floor space occupied between equipment, and can prevent the entire line from stopping due to the failure of a single machine. When one spinning machine has a problem, the entire conveyor line can be adjusted to feed material to the spinning machine in normal condition.

[0049] 3. The automatic vertical spinning production line for air conditioning liquid receivers in this application has a pre-positioned cleaning device to remove surface impurities, preventing rust and dirt on the cylinder surface from falling off during processing and interfering with the normal processing flow.

[0050] 4. The automatic vertical spinning production method for air conditioning liquid receivers in this application achieves seamless integration from cleaning to final assembly of the cylinder through a fully automated design of the feeding bus, branch line, spinning machine, tube expanding and polishing machine, pressing machine, second spinning machine, and tube loading machine. Through the coordinated control of sensing elements, tube clamping cylinders, and material blocking components, it ensures that the two first vertical spinning machines obtain cylinders evenly, avoiding efficiency bottlenecks caused by uneven material supply from a single machine.

[0061] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0062] The present invention will now be described with reference to the accompanying drawings.

[0063] The specific solution adopted is as follows:

[0064] like Figures 1-7 As shown, the present invention provides an automatic vertical spinning production line for air conditioning liquid receivers, including a first vertical spinning machine 1, a tube expanding and polishing machine 2, a pressing machine 3, a second vertical spinning machine 4, and a tube loading machine 5 arranged sequentially in the x-axis direction;

[0065] The conveying device 6 is located on one side of the first vertical spinning machine 1 and the second vertical spinning machine 4, and includes a conveyor line that conveys along the x-axis and multiple gantry frames that cross the conveyor line; each gantry frame is provided with a gripper assembly that can be lifted and moved along the y-axis and can be rotated, the gripper assembly being used to send the cylinder to be processed to the inlet of the vertical spinning machine and to remove the spun cylinder from the inlet of the vertical spinning machine;

[0066] The gripper assembly can be a two-finger gripper, with polyurethane or silicone pads embedded on the inside of the fingers to prevent scratching the cylinder surface; the gantry frame structure consists of two vertical columns and a horizontal beam, with linear guide rails installed on the surface of the beam along the direction of the horizontal beam, and slider 81 assemblies configured on the guide rails. The slider 81 assembly is directly mounted with a lifting cylinder, and a bracket is connected to the end of the cylinder piston rod. A motor is mounted on the bracket, and the motor output shaft is connected to a rotating bracket, with the gripper assembly fixed at the end of the bracket; the above-mentioned drive structure and gripper module are mature solutions in the field of industrial automation and are widely used in sorting, assembly and other scenarios, and this application will not elaborate on the technical details.

[0067] The transfer device 8 is set on the table of the pipe expanding and polishing machine 2, the pressing machine 3, and the pipe loading machine 5, and includes parallel gripper units 86; each gripper unit 86 can independently grip and release the cylinder, and the distance between adjacent gripper units 86 is fixed; the parallel gripper units 86 can reciprocate along the x-axis to realize the continuous equidistant movement of the cylinder.

[0068] The loading station is located on the table of the pipe expanding and polishing machine 2, the pressing machine 3, and the pipe loading machine 5. The loading station is equipped with a positioning component 7 and a detection component. The positioning component 7 is located at the intersection of the path range that the gripper assembly can cover when moving along the y-axis and the path range that the gripper unit 86 can cover when moving along the x-axis, and is used to position and temporarily store the cylinder. The detection component is used to detect whether there is material at the loading station and transmits the detection signal to the controller. The controller controls whether the gripper assembly or gripper unit 86 of the next process can move to transfer the cylinder to each station for processing according to the detection signal, so as to realize fully automatic continuous production.

[0069] The automatic vertical spinning production line for air conditioning liquid receivers disclosed in this application has each processing device arranged sequentially along the x-axis. Combined with a conveying device 6 and a transfer device 8, it forms a continuous production process. The gripper assembly 68 of the conveying device 6 can accurately deliver the cylinder to be processed to the inlet of the vertical spinning machine and remove the spun cylinder. The parallel gripper unit 86 of the transfer device 8 can reciprocate along the x-axis, enabling continuous equidistant movement of the cylinder between the tube expanding and polishing machine 2, the pressing machine 3, and the tube loading machine 5. This avoids the time wasted during manual transfer, significantly shortens the processing cycle, and improves production efficiency, especially in large-scale production. The cylinder can be processed sequentially through the first vertical spinning machine 1, the tube expanding and polishing machine 2, the pressing machine 3, the second vertical spinning machine 4, and the tube loading machine 5 without manual intervention in the connection between processes, reducing the possibility of production interruptions and further improving production efficiency.

[0070] The detection unit at the loading station can detect in real time whether there are any cylinders temporarily stored and transmit the signal to the controller. Based on the detection signal, the controller controls the gripper assembly or gripper unit 86 of the next process to move and transfer the cylinders to each processing station, ensuring the real-time and accurate transmission of information during production. Production managers can monitor the production progress and cylinder position information of each process in real time through the control system, which is beneficial for rationally planning and scheduling production. The entire production line achieves fully automated transfer of cylinders between processes, eliminating the need for workers to perform heavy transfer work. Workers only need to handle a few operations such as initial loading and final unloading, greatly reducing the labor intensity of workers and improving work comfort and safety.

[0071] Each processing equipment is arranged sequentially along the x-axis. The conveying device 6 is located on one side of the first and second vertical spinning machines 4. It adopts a conveyor line that conveys along the x-axis and a gantry frame that spans the conveyor line. This layout makes full use of space and reduces the floor space occupied between the equipment.

[0072] Positioning component 7 ensures smooth transfer of cylinders between different devices via gripper assemblies and gripper units 86. The gripper assembly primarily handles cylinder transfer between the vertical spinning machine and the conveyor line; its range of movement along the y-axis determines its reach to the inlet of the vertical spinning machine and specific positions on the conveyor line. Gripper unit 86 moves along the x-axis between the tube expander / brusher 2, press-fitter 3, and tube installer 5, facilitating cylinder transfer between these devices. Positioning component 7 is located at the intersection of these paths. Both the gripper assembly and gripper unit 86 can accurately reach the position of positioning component 7 within their range of movement, thus stably gripping or placing the cylinder and ensuring a smooth transfer process.

[0073] Because the positioning component 7 clearly defines the handover position, the gripper assembly and gripper unit 86 do not need to search the cylinder over a large area, enabling them to quickly and accurately perform gripping and placement operations. This significantly shortens the handover time between processes and improves the overall operating efficiency of the production line. The stable handover process makes the production rhythm between various devices more coordinated, reducing production interruptions and waiting times caused by poor handover, achieving continuous and smooth production, and facilitating large-scale, high-efficiency production.

[0074] The positioning component 7 can be installed on one side of the table with the help of the mounting plate, without occupying the main processing area in the middle of the table, ensuring that equipment such as the pipe expansion and polishing machine 2, the pressing machine 3, and the pipe fitting machine 5 have enough space for normal processing operations.

[0075] In actual production, to improve production efficiency and meet the demands of large-scale production, it is often necessary to set up multiple spinning machines for simultaneous processing. However, according to existing technical solutions, each spinning machine needs to be equipped with an independent conveyor mechanism (including at least one input line and one output line). This means that when multiple spinning machines are set up, multiple independent conveyor lines need to be established accordingly. This layout requires a large amount of production space, which undoubtedly increases the company's production costs and operational pressure. Too many conveyor lines not only make the production workshop appear crowded and cluttered, but also affect the operation of production personnel and the efficiency of logistics flow, reducing the flexibility and responsiveness of the entire production system. Each independent conveyor line needs to be equipped with a corresponding drive device, such as a motor and transmission chain, to realize the function of transporting the cylinder. Multiple conveyor lines mean that multiple drive devices need to operate simultaneously, which not only increases the equipment procurement cost, but also leads to a significant increase in energy consumption.

[0076] To address the aforementioned issues, in a preferred embodiment of this application, the conveyor line includes a loading bus 60, a unloading bus 61, and loading sub-lines 62. The loading bus 60 and unloading bus 61 correspond to multiple parallel first vertical spinning machines 1 or second vertical spinning machines 4. Each vertical spinning machine has two spinning inlets corresponding to two loading sub-lines 62 and corresponding to a first gantry frame 63, a second gantry frame 64, and a third gantry frame 65. The gripper assembly of the first gantry frame 63 transfers the cylinders to be processed on the loading bus 60 to the two secondary loading sub-lines 62. The gripper assemblies on the second gantry frame 64 and the third gantry frame 65 respectively send the cylinders to be processed on the two loading sub-lines 62 to the spinning inlets and respectively transfer the spun cylinders to the unloading bus 61.

[0077] By coordinating the "main-secondary" graded conveying system with the gantry frame gripper assembly, the production linkage of multiple spinning machines is realized. Multiple spinning machines are arranged side by side, with the main feeding / unloading conveyor line extending longitudinally along the equipment, and the secondary feeding line adjacent to the equipment and parallel to the main feeding / unloading conveyor line, forming a "main trunk + branch" structure. The gripper assembly on the gantry frame mechanism achieves span gripping through horizontal and vertical lifting movements, realizing the linkage between the main trunk and branches. Compared with traditional independent conveyor lines, the workshop area occupied is greatly reduced, the number of drive devices is reduced, and energy consumption is greatly reduced.

[0078] In addition, this layout can prevent the entire line from stopping due to the failure of a single piece of equipment. When one of the spinning machines has a problem, the entire conveyor line can be adjusted to feed material to the spinning machine that is in normal condition.

[0079] As a preferred embodiment of this application, it also includes a cleaning device 9, which is set in front of the first vertical spinning machine 1. The loading bus 60 loads the cleaned cylinder onto the loading bus 60 through the gripper assembly on the fourth portal frame 66. The cylinder on the unloading bus 61 is automatically unloaded to the loading station of the tube expander and polisher 2 / tube packer 5 through the gripper assembly on the fifth portal frame 67.

[0080] Without a cleaning device, rust and dirt on the cylinder surface may flake off during processing, interfering with the normal workflow. For example, rust falling off during spinning may affect the operation of the spinning machine, leading to uneven spinning. If it enters processing equipment such as spinning machines and tube flaring and polishing machines, it will accelerate equipment wear and shorten the equipment's lifespan. A cleaning device removes these impurities beforehand, avoiding such interference and ensuring the stability and continuity of each processing step. The cleaning device can pre-treat the cylinder; operations like sandblasting can effectively remove rust and dirt from the outer surface of the cylinder. A cleaner cylinder surface provides an ideal processing foundation for subsequent spinning, flaring, and other processing steps. For instance, in the spinning process, a clean cylinder surface reduces friction and impurity interference with the spinning tools, making the spinning process smoother and reducing processing difficulty.

[0081] The feeding bus 60 continuously conveys the cylinders. Without effective measures, various abnormal situations may occur when the gripper assembly picks up the cylinders. For example, the cylinder may continue to be conveyed forward due to inertia, causing the gripper to fail to grasp it accurately; or a later cylinder may arrive at the front and be picked up by the gripper along with the previous cylinder, resulting in incorrect quantity picking or unstable gripping. These problems will seriously affect the accuracy and efficiency of subsequent processing steps, and may even lead to equipment malfunctions and product quality issues.

[0082] To address the aforementioned issues, a clamping cylinder is installed in front of the pickup positions corresponding to the loading bus 60, loading branch line 62, and unloading bus 61 of the gripper assembly, while a stop is installed behind it. The clamping cylinder blocks subsequent cylinders, and the stop prevents the cylinder to be picked up from continuing to move forward due to conveying inertia, ensuring that the gripper can accurately grip only one cylinder at a time. A sensor is installed between the clamping cylinder and the stop to detect the presence of material. The sensor can monitor the presence of a cylinder at that position in real time, and the gripper assembly will only perform the gripping action when a cylinder is detected. This further improves the accuracy and reliability of gripping, avoiding gripping failures or abnormalities caused by misjudgment.

[0083] For safe material feeding, the placement position of the feeding bus 61 must be clear and unobstructed. If there are cylinders or other obstructions at the placement position, direct feeding may cause them to fall or collide, affecting product quality and production safety. Therefore, a safety light curtain is installed at the placement position of the gripper assembly corresponding to the feeding bus 61. The safety light curtain works by blocking the light beam when an object enters the area, emitting a signal to the gripper assembly that feeding is not permitted. The gripper assembly will only perform the feeding action when the safety light curtain detects that the placement position is safe and unobstructed, thus ensuring the safety and accuracy of the feeding process.

[0084] A clamping cylinder is installed between the feeding positions of two adjacent gripper assemblies corresponding to the feeding bus 61. After the preceding gripper assembly lowers the cylinder, to prevent the cylinder from colliding or misaligning with the cylinder lowered by the following gripper assembly due to excessive speed during conveying, the clamping cylinder is activated to temporarily stop it. After the following cylinder is lowered, the clamping cylinder returns to its original position, clearing the passage so that the conveyor line can continue to operate normally. This design ensures that the cylinders are arranged in an orderly manner during the feeding process, avoiding chaos and collisions, and improving the efficiency and accuracy of feeding.

[0085] The entire conveyor line's operating logic is designed to ensure the accuracy and safety of each link, forming a complete and efficient conveyor line operating system that can meet the stringent requirements for cylinder conveying during liquid storage tank processing, thereby improving production efficiency and product quality.

[0086] In a preferred embodiment of this application, the first vertical spinning machine 1 / second vertical spinning machine 4 is provided with a slide table 10 that can move along the y-axis. The slide table 10 is provided with a loading position and a unloading position. The gripper assemblies on the second portal frame 64 and the third portal frame 65 respectively send the cylinders to be processed from the two loading lines 62 to the loading position or remove them from the unloading position. The loading position is provided with a first sensor to sense whether there is material and transmit the information to the controller. The controller controls the slide table 10 to move to the spinning position corresponding to the loading position. The unloading position is provided with a second sensor to sense whether there is material and transmit the information to the controller. The controller controls the gripper assembly to move to the unloading position to pick up the processed cylinder.

[0087] Specifically, when the cylinders to be processed on the two feeding lines 62 reach the designated positions, the gripper assemblies on the second gantry frame 64 and the third gantry frame 65 begin to operate, grabbing the cylinders and sending them to the feeding position of the spinning machine. At this time, the first sensor at the feeding position detects the presence of a cylinder and immediately sends a signal to the controller. After receiving the signal, the controller quickly controls the slide table 10 to move along the y-axis, so that the feeding position precisely corresponds to the spinning position. In this way, the cylinder is in the optimal spinning processing position, preparing it for subsequent processing steps.

[0088] After the slide table 10 aligns the loading position with the spinning position, the spinning mechanism 11 of the vertical spinning machine descends to clamp the cylinder and remove it from the loading position, thus beginning the spinning process on the cylinder. The spinning machine shapes the cylinder by rotating and extruding it to achieve the required size and shape.

[0089] Once the spinning process is complete, the cylinder is placed at the unloading position of the slide 10. The second sensor at the unloading position begins to monitor whether there is a completed cylinder at the unloading position. Once a cylinder is detected, the second sensor immediately sends a signal to the controller. After receiving the signal, the controller controls the gripper assembly to move to the unloading position. The gripper assembly picks up the completed cylinder and removes it from the unloading position, placing it on the unloading bus 61.

[0090] The loading position uses a cylindrical slot seat with an inner diameter larger than the outer diameter of the cylinder. This is to facilitate the subsequent lowering and clamping of the spinning mechanism 11 to retrieve the cylinder from the loading position. However, when the gripper assembly vertically places the cylinder into the cylindrical slot, if there is a misalignment, and the slide table 10 moves to align the loading position with the corresponding spinning position, the cylinder cannot be accurately inserted into the mold cavity of the spinning mechanism 11 when it descends. This leads to production interruption, requiring manual intervention and adjustment, which seriously affects production efficiency and product quality. To solve the cylinder misalignment problem, a straightening component is installed at the slot opening. Specifically, it can be one of two structures: First, a chuck is installed at the slot opening, with the center hole of the chuck matching the inner diameter of the cylindrical slot seat. When the sensor detects material, the chuck starts first, using the grippers to move towards the center of the center hole to position and straighten the cylinder, ensuring it is in the correct position and preventing misalignment. Alternatively, two alignment cylinders can be installed on both sides of the cylindrical slot seat. The piston rod of the cylinder is connected to the arc-shaped section of the adapter cylinder. After sensing the presence of material, the alignment cylinder is activated, pushing the arc-shaped section to move closer to the cylinder, straightening the cylinder from both sides and keeping it in a vertical state, which facilitates the operation of the subsequent spinning mechanism 11.

[0091] Due to differences in material properties, the taper after spinning may be problematic. If this is not detected and adjusted in time during production, it can lead to a large number of defective products, resulting in resource waste and increased production costs. Therefore, in this embodiment, the unloading position is designed as a slot in a conical cavity, and laser sensors are installed at different positions inside the conical cavity. After each spinning operation, the spinning mechanism 11 aligns with the unloading position, lowers and releases the clamped spinning cylinder, allowing the cylinder to enter the conical cavity, with the spinning end corresponding to the conical cavity. The laser sensor transmits distance measurement data to the controller, using the distance to completely fit the conical cavity as a reference value. If the distance measurement data is greater than the reference value, it indicates a large taper and a harder material. Based on the detection results of the laser sensor, if adjustment is needed, the controller can control the spinning mechanism 11 to adjust the extrusion pressure, correcting the taper problem at this step and preventing the production of a large number of defective products.

[0092] The spinning process can be divided into two steps: rough spinning: In the rough spinning stage, many wrinkles will appear on the outer edge of the cone. This is a normal process phenomenon, and its purpose is to initially shape the cone into the cylinder. Fine spinning: After rough spinning, the fine spinning process is carried out. Fine spinning can make the cone surface smoother, improving the appearance quality and dimensional accuracy of the product. The step-by-step spinning process, combined with taper detection and adjustment, improves the stability and reliability of the spinning process, ensuring the consistency of product quality.

[0093] In a preferred embodiment of this application, the transfer device 8 includes two slide rails 80 mounted on the table of the pipe expanding and polishing machine 2 / pressing machine 3 / pipe loading machine 5 and a slider 81 that cooperates with the slide rails 80. A rack is provided between the two slide rails 80. An L-shaped support plate is provided on the upper side of the slider 81. A drive motor 84 is provided on the part of the support plate parallel to the slide rails 80. The output shaft of the drive motor 84 is provided with a gear. The gear meshes with the rack. When the drive motor 84 is running, the rotational motion of the motor is converted into linear motion of the slider 81 on the slide rails 80 through the interaction of the gear and the rack, thus realizing the effective transmission of power. The support plate and the vertical part of the slide rail 80 are slidably connected to the gripper mounting frame 85. The gripper mounting frame 85 is connected to the lifting mechanism 88. The gripper unit 86 is installed on the gripper mounting frame 85. Driven by the lifting mechanism, the gripper mounting frame 85 can move up and down. For the gripper unit 86 that needs to achieve the flipping function, a rotating motor is first installed on the gripper mounting frame 85. The motor output shaft passes through the gripper mounting frame 85 and connects to the support block. Then the gripper unit 86 is installed on the support block. The gripper unit 86 is a cylinder gripper. Like the gripper assembly, a flexible contact part is set on the side of the gripper that contacts the cylinder to prevent the cylinder from having indentations or overall deformation during clamping.

[0094] See Figure 4 The tube expansion and polishing machine 2 has a tube expansion station 20 and an inner wall polishing station 21. The positioning part 7 of the loading station on the table of the tube expansion and polishing machine 2 is cylindrical. The diameter of the end of the cylindrical part is adapted to the inner diameter of the cylinder, and the lower side is larger than the outer diameter of the cylinder. The cylinder opening side of the spinning end is inserted into the upper end of the cylinder. There are three gripper units 86 with a spacing adapted to the tube expansion station 20 and the inner wall polishing station 21. The gripper unit 86 at the end is connected to the flipping motor 87 to realize the flipping of the cylinder so that the opening side faces upward during the next pressing.

[0095] See Figure 5The press-fitting machine 3 has a first partition pre-installation station 30, a first partition press-fitting and grooving station 31, a second partition pre-installation station 32, a second partition press-fitting and grooving station 33, a filter pre-installation station 34, and a filter press-fitting and grooving station 35. The gripper unit 86 has seven grippers with a spacing adapted to the distance of each station. The filter press-fitting and grooving station 35 also has a feeding station 36 on one side, which is opposite to the feeding station. The cylinder opens upward and passes through the above stations in sequence to realize the installation of two partitions and a filter screen. Inward protrusions are set on the upper and lower sides of the installation position to restrict the position of the partitions and filter screen inside the cylinder.

[0096] See Figure 6 The tube loading machine 5 has a first foreign object suction station 50. The positioning component 7 is located on the upper side of the first foreign object suction station 50. After the cylinder is placed on the upper side, it vibrates to absorb some dirt in the cylinder. The cylinder comes to the flux storage liquid cup station 51 to dip in flux liquid. It comes to the second foreign object suction station 52 for vibration suction. The end thin tube is installed at the inner tube pre-assembly station 53 and the inner tube pressing station 54. There are five gripper units 86 with a spacing adapted to the distance of each station. Similarly, the conveying or transferring of this application can be connected to welding equipment or other equipment to realize the fully automated processing.

[0097] In addition, since both the pressing and pipe-loading processes involve the spinning and closing ends being located on the lower side, the positioning parts 7 on the pressing machine 3 and the pipe-loading machine 5 have cylindrical grooves at their ends, and the inner diameter of the cylindrical grooves is adapted to the outer diameter of the cylinder.

[0098] The production method of the automatic vertical spinning production line for air conditioner liquid receivers includes the following steps:

[0099] S1: Cylinder cleaning and rust removal

[0100] The cut cylinder is placed vertically and passed through the cleaning device. The cleaning components inside the device perform rust removal and cleaning on the outer surface of the cylinder, removing iron oxide rust and dirt, ensuring the cleanliness of the cylinder surface, and providing a good foundation for subsequent processing.

[0101] S2: Preparation for cylinder loading bus 60 allocation

[0102] After the cleaned cylinder comes out of the cleaning device and reaches the designed position, the sensing element set at the position detects the cylinder. Then, the gripper assembly on the fourth gantry frame 66 picks up the cylinder, flips it 90 degrees, and places it horizontally on the loading bus 60.

[0103] S3: Feed bus 60 provides balanced material supply for the spinning machine.

[0104] Cylinders continuously fed along the feeding bus 60 at designed intervals arrive at the picking position of the first vertical spinning machine 1. After the sensing element detects the cylinder at this position, the clamping cylinder and the blocking element activate to ensure that there is only one cylinder at the picking position. The gripper assembly on the first gantry frame 63 picks up at least two cylinders in a row and distributes them to the two feeding lines 62. Then, the corresponding clamping cylinder and blocking element stop working, and the cylinder continues to move along the feeding bus 60 to the picking position of the second first vertical spinning machine 1. Similarly, after at least two cylinders are placed, the clamping cylinder and blocking element at the previous position resume working. This process is repeated to distribute the same number of cylinders to the two first vertical spinning machines 1.

[0105] S4: Preparation for feeding cylinder at feeding line 62

[0106] The cylinder to be processed at the feeding line 62 moves to the picking position of the line. After the sensor detects the cylinder, the clamping cylinder and the baffle start to work. The gripper assembly on the second portal frame 64 and the third portal frame 65 picks up the cylinder, rotates it 90 degrees, and places it vertically on the feeding position of the first / second spinning machine slide 10.

[0107] S5: Spinning and finishing operation on a spinning machine

[0108] After the sensor on the loading position detects the cylinder, the slide table 10 moves along the y-axis to the spinning position. The spinning mechanism 11 at the spinning position descends and installs the cylinder at the loading position onto the mold. Then the slide table 10 retracts and begins the spinning and closing operation. After the slide table 10 retracts, a new cylinder is simultaneously placed into the loading position. At this time, it is necessary to wait for the previous cylinder to complete the spinning. After the spinning is completed, the slide table 10 re-enters, first aligning the unloading position with the spinning position to receive the spun cylinder. Then the slide table 10 continues to move forward until the loading position aligns with the spinning position to install the new cylinder. Finally, the slide table 10 retracts.

[0109] S6: Spinning completed cylinder unloading and temporary storage

[0110] After the sensor at the unloading position detects the presence of material, the gripper assembly on the second portal frame 64 and the third portal frame 65 picks up and removes the cylinder after one end has been spun, and places it into the unloading bus 61; the safety light curtain at the placement position senses whether there is material. If there is material, the gripper assembly will not release the material temporarily to ensure that the cylinder is placed in an orderly manner.

[0111] S7: The cylinder is transferred to the tube expander and polishing machine 2

[0112] As the cylinder moves to the end along the feeding bus 61, the sensing element detects the presence of material, and the clamping cylinder and the material blocking element are activated. Then, the gripper assembly on the fifth portal frame 67 picks up the cylinder and flips it over, sending it to the feeding station of the tube expander and brushing machine 2, so that the un-spun end is placed facing down on the outside of the cylindrical end.

[0113] S8: Pipe Expanding and Polishing Machine 2 Processing

[0114] After the inspection unit detects that there is material at the loading station of the tube expanding and polishing machine 2, the moving device is activated. The gripper unit 86 first grips the cylinder, then lifts, moves horizontally, and lowers it to the tube expanding station 20 for tube expanding. After expanding, the opening side of the tube is flared. Next, the second gripper unit 86 grips the cylinder, lifts, moves horizontally, and lowers it to the inner wall polishing station 21 for inner wall polishing. Then, the third gripper unit 86 grips the cylinder, lifts, moves horizontally, and flips it, placing the cylinder with the expanded hole side facing up at the loading station of the pressing machine 3.

[0115] S9: Assembly Operation of Press Fitting Machine 3

[0116] With the expanded hole side of the cylinder facing upwards and the closed side located in the cylindrical groove of the positioning component 7, after the detection component detects the presence of material, the transfer device 8 on the tube loading machine 5 begins to deliver material in the same way as the transfer device 8 in S8, completing the assembly of the partition and filter, and sending the assembled cylinder to the unloading station 36.

[0117] S10: Second vertical spinning machine, 4-stage spinning

[0118] After completing the above process, the cylinder passes through the conveyor line of the second vertical spinning machine 4 and repeats steps S6-S7 to achieve the other end of the cylinder being spun and closed.

[0119] S11: Final processing of pipe loading machine 5

[0120] The cylinder with both ends closed is placed at the loading station of the tube loading machine 5. The loading station is the same location as the first foreign object dust collection station 50. The cylinder is delivered sequentially by the transfer device 8 to each station for processing, and finally the processing flow of the entire production line is completed.
