Description

Technical Field

[0001] This application belongs to the field of air conditioning liquid receiver manufacturing, and in particular relates to a fully automated continuous production line for air conditioning liquid receivers. Background Technology

[0002] In refrigeration and air conditioning systems, the compressor, as a core component, is crucial for the efficient and reliable operation of the entire system. The receiver, 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 under unstable conditions. The existing receiver manufacturing process mainly includes several steps: First, a spinning machine is used to spin-finish one end of an open-end cylindrical body; second, a tube expander and polishing machine is used to expand the other end of the cylinder, increasing the opening size to facilitate the installation of subsequent components. After flaring, the inside of the cylinder needs to be cleaned to remove metal shavings, dust, and other impurities generated during processing; third, a CNC press-fitting machine is used to install the partitions and filters, pressing them into the cylinder; fourth, the other end of the spinning machine is spun shut; fifth, a tube fitting machine is used to install the end gas pipes.

[0003] In the existing liquid storage container manufacturing process, some steps still rely on manual transfer between processes. Since manual transfer is time-consuming and labor-intensive, and may involve waiting and delays, the overall processing cycle is prolonged, and production efficiency cannot be effectively improved. This inefficiency is particularly pronounced in large-scale production, becoming a significant factor restricting the expansion of liquid storage container production scale and cost reduction. Reliance on manual transfer increases the labor intensity of workers, and the presence of manual transfer hinders the smooth and transparent flow of materials and information in the production process. Production managers struggle to accurately monitor the production progress of each process and the location of liquid storage containers in real time, which is detrimental to the rational arrangement and scheduling of production plans. In the event of production abnormalities, such as quality problems in a process, it is difficult to detect and take effective measures to adjust in a timely manner, leading to chaos in the entire production line and affecting normal production operations. Therefore, the existing technology needs further improvement and enhancement. Utility Model Content

[0004] This utility model provides a fully automated continuous production line for air conditioner liquid receivers. In the existing air conditioner liquid receiver processing flow, some processes rely on manual transportation. Manual transportation is time-consuming and labor-intensive, and waiting and delays are prone to occur during transportation, resulting in a longer processing cycle. The problem of low efficiency is even more prominent when producing on a large scale, which restricts the expansion of production scale and cost reduction.

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

[0006] A fully automated continuous 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 along the x-axis.

[0007] The conveying device is located on one side of the first and second vertical spinning machines, including a conveyor line that conveys along the x-axis and multiple gantry frames that cross the conveyor line. Each gantry frame is equipped with a gripper assembly that can be lifted and moved along the y-axis. The gripper assembly is used to send the cylinder to be processed to the inlet of the vertical spinning machine / remove the spun cylinder from the inlet of the vertical spinning machine.

[0008] The transfer device, installed on the table of the pipe expander / brusher, presser, and pipe packer, includes parallel gripper units. Each gripper unit can independently grip and release the cylinder, and the spacing between adjacent gripper units is fixed.

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, realizing fully automatic continuous production.

[0009] In a preferred embodiment, the positioning element is located at the intersection of the path range that the gripper assembly can cover when it moves along the y-axis and the path range that the gripper unit can cover when it moves along the x-axis.

[0010] In the preferred implementation, the positioning component of the tube expanding and brushing machine table is cylindrical, with the end diameter of the cylindrical component matching the inner diameter of the cylinder and the lower side being larger than the outer diameter of the cylinder.

[0011] 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.

[0012] In a preferred implementation, the conveyor line includes a loading bus, a unloading bus, and loading sub-lines. Each vertical spinning machine corresponds to two loading sub-lines and to a first gantry frame, a second gantry frame, and a third gantry frame. The gripper assembly of the first gantry frame transfers the cylinders 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 cylinders to be processed on the two loading sub-lines to the spinning inlet and respectively transfer the spun cylinders to the unloading bus. The loading bus automatically loads the cylinders through the gripper assembly on the fourth gantry frame, and the unloading bus automatically unloads the cylinders through the gripper assembly on the fifth gantry frame.

[0013] In the preferred implementation, a clamping cylinder is provided on the front side of the picking position of the feeding bus, the feeding branch line and the unloading bus, and a blocking cylinder is provided on the rear side. A safety light curtain is provided at the placement position of the unloading bus.

[0014] 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.

[0015] In a preferred embodiment, the tube expanding and polishing machine has a tube expanding station and an inner wall polishing station. The gripper unit has three grippers with a spacing adapted to the tube expanding station and the inner wall polishing station. The gripper unit at the end is connected to a flipping motor to achieve tube flipping.

[0016] 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.

[0017] 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.

[0018] The above structure has the following beneficial effects:

[0019] By adopting the fully automated continuous production line for air conditioning liquid receivers of this application, each processing equipment is arranged sequentially along the x-axis, forming a continuous production process in conjunction with a conveying device and a transfer device. The gripper assembly of the conveying device 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 of the transfer device can reciprocate along the x-axis, realizing continuous equidistant movement of the cylinder between the tube expanding and polishing machine, the pressing machine, and the tube loading machine, avoiding the time wasted in the manual transfer process, greatly shortening the processing cycle, and improving production efficiency, especially when the advantages are more obvious in large-scale production. The cylinder can be processed sequentially through the first vertical spinning machine, the tube expanding and polishing machine, the pressing machine, the second vertical spinning machine, and the tube loading machine, without the need for manual intervention in the connection between processes, reducing the possibility of production interruption and further improving production efficiency.

[0028] 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 this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; 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. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] The present invention will now be described with reference to the accompanying drawings.

[0033] The specific solution adopted is as follows:

[0034] like Figure 1-5 As shown, this utility model provides a fully automatic continuous 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 along the x-axis.

[0035] The conveying device 6 is located on one side of the first and second vertical spinning machines 4, including a conveying line along the x-axis and multiple gantry frames spanning the conveying line. Each gantry frame is equipped with a gripper assembly that can be lifted and moved along the y-axis. The gripper assembly 68 adopts a cylinder gripper design. The gantry frame serves as the support structure for the entire device and is constructed from two vertical beams and one horizontal beam. A slide rail 80 is set on the crossbeam and equipped with a matching slider 81. The slider 81 can slide smoothly along the slide rail 80. The slider 81 is tightly connected to the mounting plate, and the mounting plate is further connected to the lifting mechanism. There are two common choices for the lifting mechanism, such as a motor screw combination or a cylinder. When a cylinder is used as the lifting mechanism, the piston rod end of the cylinder is connected to the gripper assembly to realize the y-axis movement and lifting of the gripper assembly. Furthermore, the end of the cylinder is connected to the motor mounting bracket, the motor mounting bracket is connected to the motor, and the gripper assembly is connected to the motor rod, so that it can be flipped. The gripper assembly is used to send the cylinder to be processed to the inlet of the vertical spinning machine / remove the spun cylinder from the inlet of the vertical spinning machine.

[0036] The transfer device 8 is installed on the table of the tube expander and polisher 2, the presser 3, and the tube packer 5. It includes parallel gripper units 86, each of which can independently grip and release the cylinder. The spacing between adjacent gripper units 86 is fixed. The parallel gripper units 86 can reciprocate along the x-axis to achieve continuous equidistant movement of the cylinder. The table of the tube expander and polisher 2, the presser 3, and the tube packer 5 is also equipped with a loading station. The loading station is equipped with a positioning component 7 and a detection component. The positioning component 7 can position and temporarily store the cylinder. The detection component can detect whether there is material at the loading station. The detection component can be a laser sensor. The detection component transmits a signal to the controller. The controller controls whether the gripper assembly or gripper unit 86 of the next process moves to transfer the cylinder to each station for processing, so as to realize fully automatic continuous production.

[0037] By adopting the fully automated continuous production line for air conditioning liquid receivers of this application, each processing equipment is arranged sequentially along the x-axis, and together with the conveying device 6 and the transfer device 8, a continuous production process is formed. The gripper assembly 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, realizing the continuous equidistant movement of the cylinder between the tube expanding and polishing machine 2, the pressing machine 3, and the tube loading machine 5, avoiding the time wasted in the manual transfer process, greatly shortening the processing cycle, and improving production efficiency, especially when the advantages are more obvious 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 the need for manual intervention in the connection between processes, reducing the possibility of production interruption and further improving production efficiency.

[0038] 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.

[0039] 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.

[0040] Furthermore, the positioning element 7 is located at the intersection of the path range covered by the gripper assembly when moving along the y-axis and the path range covered by the gripper unit 86 when moving along the x-axis. This is crucial for ensuring smooth transfer of the cylinder between different devices via the gripper assembly and gripper unit 86. The gripper assembly is mainly responsible for transferring the cylinder between the vertical spinning machine and the conveyor line. Its movement range along the y-axis determines its ability to reach the inlet of the vertical spinning machine and specific positions on the conveyor line. The gripper unit 86 moves along the x-axis between the pipe expanding and polishing machine 2, the pressing machine 3, and the pipe loading machine 5, realizing the transfer of the cylinder between these devices. With the positioning element 7 located at the intersection of these paths, both the gripper assembly and the gripper unit 86 can accurately reach the position of the positioning element 7 within their movement range, thus stably gripping or placing the cylinder and ensuring a smooth transfer process.

[0041] 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.

[0042] In addition, see Figure 3 , Figure 4 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 the pipe expansion and polishing machine 2, pressing machine 3, pipe loading machine 5 and other equipment have enough space for normal processing operations.

[0043] In a preferred embodiment of this application, the positioning element 7 on the table of the tube expanding and brushing machine is cylindrical, with the diameter of the end of the column matching the inner diameter of the cylinder and the lower side larger than the outer diameter of the cylinder. The unclosed end of the cylinder is temporarily placed against the upper part of the positioning element 7. The diameter of the end of the cylindrical positioning element 7 matches the inner diameter of the cylinder after it has been spun and closed. When the cylinder is placed on the positioning element 7, the end can be tightly inserted into the cylinder, utilizing the constraint of the inner wall of the cylinder to achieve precise radial positioning. This positioning method effectively prevents radial movement of the cylinder on the table, ensuring the positional stability of the cylinder during the tube expanding and brushing process, thereby improving processing accuracy and product quality.

[0044] Furthermore, the positioning element 7 on both the press-fitting machine 3 and the pipe-loading machine 5 has a cylindrical groove at its end, the inner diameter of which is adapted to the outer diameter of the cylinder. In the press-fitting process, the cylinder opening faces upwards and the constricted end faces downwards—a specific process requirement. The cylindrical groove at the end of the positioning element 7 can well accommodate the constricted end of the cylinder. Utilizing the matching relationship between the inner diameter of the cylindrical groove and the outer diameter of the cylinder, precise positioning of the cylinder on the press-fitting machine 3 is achieved. This positioning method ensures the cylinder's stable position during the press-fitting process, preventing displacement due to external forces, thus guaranteeing press-fitting quality. The cylinders processed by the pipe-loading machine 5 are constricted at both ends. The cylindrical groove design can simultaneously accommodate either constricted end of the cylinder, providing a stable support and positioning structure for the cylinder, maintaining a fixed position and posture on the table, facilitating accurate gripping and operation by the gripper unit 86 of the pipe-loading machine 5.

[0045] See Figure 1 The conveyor line includes a loading bus 60, a unloading bus 61, and loading sub-lines 62. Each vertical spinning machine corresponds to two loading sub-lines 62 and to the first portal frame 63, the second portal frame 64, and the third portal frame 65. The gripper assembly of the first portal 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 portal frame 64 and the third portal frame 65 respectively send the cylinders to be processed on the two loading sub-lines 62 to the spinning inlet, where they are received by the receiving system that moves along the y-axis direction from the spinning machine inlet. The spinning completed cylinders are then transferred from the spinning inlet to the unloading bus 61. The loading bus 60 is automatically loaded through the gripper assembly on the fourth portal frame 66, and the cylinders on the unloading bus 61 are automatically unloaded through the gripper assembly on the fifth portal frame 67.

[0046] The loading bus 60 and unloading bus 61 serve as the main channels for material transfer, while each vertical spinning mill is equipped with two loading branches 62. This layout ensures large-scale, rapid material transfer while allowing for precise material supply according to the production needs of each spinning mill. It reduces redundant configuration of conveying equipment, lowering equipment procurement costs and floor space. Material transfer between different lines is achieved through the first to fifth gantry frames 67 and their gripper assemblies. Each gantry frame undertakes a specific transfer task, with clear division of labor, forming an orderly material conveying system.

[0047] Furthermore, the loading bus 60, loading branch line 62, and unloading bus 61 are equipped with clamping cylinders at the front of their pickup positions and blocking cylinders at the rear, along with laser sensors. The laser sensors continuously monitor changes in distance at the pickup positions. When a cylinder is detected reaching the pickup position, the clamping cylinder immediately activates, preventing the following cylinder from advancing further, thus isolating it. Subsequently, the blocking cylinder activates, fixing the current cylinder in a suitable position for accurate pickup by the gripper assembly. After the gripper assembly picks up the cylinder and places it on the loading branch line 62, once the first spinning machine completes its pickup action and confirms its placement, the clamping cylinder and blocking cylinder enter a locked state and no longer respond to the laser sensor's detection signal. At this point, subsequent cylinders can smoothly move to the next pickup station, preparing for feeding subsequent spinning machines.

[0048] By coordinating the laser sensor, clamping cylinder, and baffle cylinder, only one cylinder is picked up at each location, avoiding the chaos and collisions caused by multiple cylinders entering the picking area simultaneously. This improves the accuracy and stability of the gripper assembly, providing a reliable material supply for subsequent spinning processes. When multiple spinning machines are operating simultaneously, this control mechanism provides material to each machine according to a predetermined sequence and rhythm. After the first spinning machine completes its pick-up, subsequent cylinders can move sequentially to the next workstation, achieving orderly material flow, improving the efficiency of multi-machine collaborative operation, and fully utilizing the overall capacity of the production line.

[0049] A safety light curtain is installed at the placement position of the unloading bus 61. Its main function is to detect in real time whether there is a cylinder at that position. When a cylinder is detected, the gripper assembly does not release the cylinder to prevent the cylinder from falling directly from the top of the line.

[0050] In a preferred embodiment of this application, the transfer device 8 includes two slide rails 80 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 that meshes with the rack. A gripper mounting frame 85 is slidably connected to the part of the support plate perpendicular to the slide rails 80. The gripper mounting frame 85 is connected to a lifting mechanism 88. A gripper unit 86 is installed on the gripper mounting frame 85. In this way, the gripper unit 86 can realize lifting and horizontal movement, thereby realizing continuous conveying of the cylinder over a certain distance.

[0051] For details, see Figure 3 The tube expansion and polishing machine 2 has a tube expansion station 20 and an inner wall polishing station 21. The gripper unit 86 has three grippers 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 a flipping motor 87 to realize the flipping of the cylinder.

[0052] See Figure 4 The press-fitting machine 3 has a first partition pre-assembly station 30, a first partition pressing and grooving station 31, a second partition pre-assembly station 32, a second partition pressing and grooving station 33, a filter pre-assembly station 34, and a filter pressing and grooving station 35. The gripper unit 86 is provided with seven grippers and the spacing is adapted to the distance of each station. A material unloading station 36 is also provided on one side of the filter pressing and grooving station 35, which is set opposite to the material loading station.

[0053] See Figure 5 The tube loading machine 5 has a first foreign object suction station 50, a flux storage liquid cup station 51, a second foreign object suction station 52, an inner tube pre-assembly station 53, and an inner tube pressing station 54. The gripper unit 86 is provided with five grippers and the spacing is adapted to the distance of each station. The positioning element 7 is located on the upper side of the first foreign object suction station 50.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
