Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment technology, specifically relating to a six-station fully automatic CNC press-fitting method and device for air conditioning liquid receivers. Background Technology

[0002] Other components such as baffles and filters need to be press-fitted into the liquid reservoir. The traditional method is to press the baffles or filters directly into the interior of the liquid reservoir from the opening through a press-fitting structure.

[0003] However, this method of directly pressing in the baffles or filters presents several problems. First, before the baffles are directly pressed into the reservoir, vibrations during transport due to device movement can cause inaccurate placement, incorrect angles, or even reversed orientation, leading to skewness or bending. If the support clamps the baffles downwards and presses them into the reservoir, it will result in incorrect installation. These errors can only be detected during later quality inspections. Although the pressing process may seem to complete the task initially, it actually increases the time required for later maintenance and repairs, potentially affecting the quality of components. Extended processing cycles can even lead to the scrapping of parts, resulting in a lower product qualification rate and reduced production efficiency. Secondly, the partitions themselves may have burrs, bumps, or dimensional errors. If the partitions are directly pressed into the reservoir holes to form an interference fit, it will introduce significant processing errors, easily leading to defective pressed products. Subsequent pressing of other parts will likely result in scrapped products, increasing the rework and quality inspection cycle. Furthermore, impurities and dust may enter during the pressing process. Direct pressing will cause these foreign objects to be pressed into the reservoir along with the partitions or filters, further leading to product quality problems. Summary of the Invention

[0004] This application provides a six-station fully automatic CNC press-fitting method and device for air conditioning liquid receivers, to solve the above-mentioned technical problems. The existing method of directly pressing the partition or filter into the liquid receiver results in processing errors, quality problems, and increases the time and difficulty of subsequent maintenance and quality inspection. Instead, it reduces the production cycle speed, processing efficiency and product quality.

[0005] The technical solution adopted in this application is as follows:

[0006] A fully automated CNC press-fitting method for a six-station air conditioning liquid receiver, comprising the following steps:

[0007] S1: Pre-installed partition:

[0008] The workpiece is conveyed to the unpowered spindle of the first pre-assembly station on the machine frame;

[0009] The partition is conveyed to the first moving plate assembly of the first pre-assembly mechanism on the frame by the first assembly line assembly on the frame. The first slide assembly of the first pre-assembly mechanism drives the first moving plate assembly to move upward to push the partition into the first spring plate assembly of the first pre-assembly mechanism. Multiple elastic cards of the first spring plate assembly clamp the partition.

[0010] The first slide assembly drives the first spring plate assembly to move directly above the first unpowered spindle, and the cylinder of the first spring plate assembly pushes the partition plate down to the workpiece flaring position.

[0011] S2: Pressing the partition:

[0012] The workpiece is conveyed from the first pre-assembly station to the first powered spindle of the first pressing station on the machine frame;

[0013] The workpiece is grooved on its periphery by the first groove transfer assembly of the pressing mechanism on the frame, and the partition is pressed into the corresponding mounting position of the workpiece by the first moving pressing assembly of the first pressing mechanism moving down.

[0014] S3: Repeat steps S1-S2 so that the workpiece completes the pre-assembly of the second partition in the second pre-assembly station and the press-fitting of the second partition in the second press-fitting station.

[0015] S4: Repeat steps S1-S2 so that the filter is pre-assembled in the third pre-assembly station and the filter is press-fitted in the third press-fitting station.

[0016] The six-station fully automatic CNC press-fitting method for air conditioning liquid receivers disclosed in this application can pre-install and press-fit at least two partitions and filters in the air conditioning liquid receiver. This not only avoids the significant processing errors caused by directly pressing partitions or filters, but also accelerates production cycle time, improves production efficiency, ensures production quality, and increases product qualification rate and quality. In the process of directly pressing partitions into the liquid receiver during partition transportation, the partitions may become misaligned due to vibrations caused by device movement, inaccurate placement angles, or even reversed orientation. Even if the bracket is bent, if it clamps the partition downwards and presses it into the reservoir, it will cause incorrect partition installation, resulting in a certain scrap rate of parts. Moreover, the partition itself may have burrs, bumps, or dimensional errors. If the partition is directly pressed into the reservoir hole to form an interference fit, it is easy to cause the pressed product to be unqualified. Subsequent pressing of other parts will easily result in scrapped products, increasing the subsequent rework and quality inspection cycle. In addition, impurities and foreign objects such as dust may enter during the pressing process. Direct pressing will cause these foreign objects to be pressed into the reservoir along with the partition or filter, further causing product quality problems.

[0017] Therefore, based on the above considerations, this application will perform a pre-assembly operation at the pre-assembly station before the partition or filter is press-fitted. This allows the partition or filter to first enter the flared position of the liquid reservoir, making the plane of the partition or filter basically flush with the flared position of the liquid reservoir, thus achieving basic alignment of the partition or filter. This avoids jamming or damage caused by severe misalignment at the start of the formal press-fitting process. If a problem occurs in any minor step, i.e., before press-fitting, it can be resolved in time, avoiding rework after press-fitting. Moreover, pre-assembly can be carried out simultaneously with the corresponding devices at the press-fitting station. For example, while one liquid reservoir is being press-fitted at the press-fitting station, the next liquid reservoir can be "prepared," achieving advance preparation and precise execution. After pre-assembly, the pre-assembled liquid reservoir is then press-fitted, reducing the waiting time of the devices at the press-fitting station, thereby accelerating the production cycle and further improving production efficiency and product quality.

[0018] The specific steps for pre-installing the partition include:

[0019] S11: The workpiece is transported to the loading position by a robot arm, and the transfer component picks up the workpiece from the loading position and transports it to the first unpowered spindle on the first pre-assembly station.

[0020] S12: The partition is conveyed to the first assembly line component of the first pre-assembly mechanism by the elevator, and then conveyed to the first moving plate component of the first pre-assembly mechanism by the first assembly line component;

[0021] S13: When the laser beam on the first production line assembly detects that there is a partition on the first moving plate assembly, the first slide assembly moves down, driving the first spring plate assembly to move down.

[0022] S14: Drive the first movable plate assembly of the first pre-installation mechanism to move upward to push the partition into the first spring plate assembly, and the multiple elastic clips of the first spring plate assembly clamp the partition;

[0023] S15: The first slide assembly of the first pre-installed mechanism moves horizontally to drive the first spring plate assembly to move directly above the first unpowered spindle;

[0024] S16: The partition is pushed to the workpiece flaring position by the top cylinder of the first spring plate assembly.

[0025] In this application, during the pre-assembly of the first partition, a transfer assembly clamps the workpiece and moves it from the loading position to the unpowered spindle at the first pre-assembly station. The purpose of setting up the unpowered spindle is to achieve fixed clamping of the workpiece, preventing it from tilting or rotating. The assembly line component transports the first partition to the moving plate assembly of the first pre-assembly mechanism. The moving plate assembly is capable of vertical movement, which transports the first partition to the spring plate assembly above it. The spring plate assembly is connected to the feeding slide assembly, which... The drive spring plate assembly moves horizontally and vertically, aligning it with the lower movable plate assembly. This allows the first partition in the movable plate assembly to be inserted upwards into the spring plate assembly. The movable plate assembly extends into the spring plate assembly. The first partition inside the movable plate assembly first contacts multiple elastic clips of the spring plate assembly. These clips are compressed by the first partition, and the resulting elastic force clamps the peripheral surface of the first partition, thus embedding it into the elastic plate assembly. Then, the spring plate assembly is moved to directly above the unpowered spindle via the feeding slide assembly. The top cylinder connected to the top of the spring plate assembly moves downward to push the first partition plate below precisely to the flared position of the workpiece, thus achieving the pre-installation of the first partition plate of the workpiece. This application positions and transports the partition plate and the workpiece separately. After the partition plate is conveyed in an assembly line, it needs to be precisely positioned by the cooperation of a special moving plate assembly and the spring plate assembly, further preventing jamming or inaccurate positioning of the partition plate during transportation, and accurately capturing each partition plate. The plate effectively clamps and positions each partition, ensuring it is correctly positioned directly above the workpiece. A cylinder at the top of the spring plate assembly then pushes the partition downwards from its precisely positioned position into the flared section of the workpiece. The spring plate assembly can move vertically and horizontally via the feeding slide assembly. Therefore, the distance between the partitions directly above the workpiece is small, preventing a large drop. Furthermore, the top cylinder contacts and pushes the partitions at a constant speed until they are pushed to the flared position of the workpiece.

[0026] The specific steps for pressing the partition plate include:

[0027] S21: The workpiece is transported from the first pre-assembly station to the first powered spindle of the first pressing station by the transfer assembly;

[0028] S22: Grooving is performed on the periphery of the workpiece by the grooving and transfer assembly of the first pressing mechanism, so that multiple partition mounting positions are formed on the inner wall of the workpiece along the axial direction. At the same time, the moving pressing assembly of the first pressing mechanism moves down to press the partitions into the corresponding mounting positions on the inner wall of the workpiece.

[0029] The workpiece is conveyed from the first pre-assembly station to the powered spindle of the first pressing station via a transfer assembly. The powered spindle drives the rotation of the workpiece because, during the pressing process, the partition needs to be pressed into the rotating liquid reservoir to achieve a spin pressing operation. The purpose of this spin pressing is to ensure that the partition is installed flat, smoothly, and without damage, while also ensuring the sealing and assembly quality between the partition and the inner wall of the tank. Furthermore, the partition is typically a metal disc with a rubber sealing ring, its diameter slightly larger than the inner diameter of the liquid reservoir. Therefore, the partition and the workpiece have an interference fit. If the partition is pressed directly into the tank in a straight line, the significant friction will cause it to tilt easily. Once tilting begins, the pressing resistance increases sharply, causing the partition edges to curl or deform, scratching the inner wall of the tank, damaging the smoothness of the inner wall, affecting subsequent sealing, and even generating metal fragments. It also further overloads the equipment: the pressing equipment needs to output greater pressure, which may cause damage. This application employs a first powered spindle to rotate the workpiece. Simultaneously, the rotation of the workpiece by the first powered spindle also provides rotational power to the pressing head in the first pressing mechanism above, allowing the partition to rotate and press into the workpiece. This rotational pressing is equivalent to applying a "torsional force" and a "grinding" action to the partition. This rotational force helps correct minor tilts, allowing the partition to automatically "align" itself, ensuring it always enters the tank with the most uniform force.

[0030] Therefore, the reservoir needs to be rotated in the first press-fitting station. The powered spindle can not only clamp and position the workpiece, but also rotate it and adjust its height to suit different processing requirements. While pressing the partition into the reservoir, in order to achieve precise positioning and installation of the partition in the reservoir, the workpiece is grooved on its periphery by a grooving transfer assembly. This creates an inward radial boss inside the reservoir corresponding to the grooved position. At the same time, the moving press-fitting assembly is moved down to apply pressure to the partition located at the flared position and press it into the top of the grooved boss. The top surface of the boss abuts against the bottom surface of the connecting partition, thus achieving the press-fitting and positioning of the partition. This completes the press-fitting of the first partition into the reservoir, forming an interference fit with the reservoir.

[0031] The specific steps for the workpiece to pre-assemble the second partition in the second pre-assembly station include:

[0032] The workpiece is transported to the second unpowered spindle of the second pre-installation station on the machine frame. The second moving plate assembly on the machine frame is driven to move upward and embed the second partition into the second spring plate assembly on the machine frame. The second spring plate assembly is driven to move directly above the second unpowered spindle. The second partition is pushed to the workpiece flaring position by the cylinder.

[0033] The specific steps for pressing the second partition plate onto the workpiece in the second pressing station include:

[0034] The workpiece is transported to the second powered spindle of the second pressing station on the machine frame. The second grooving and transfer assembly on the machine frame grooves the periphery of the workpiece to form a mounting position. The second moving pressing assembly on the machine frame pushes the second partition plate to press it into the mounting position of the workpiece.

[0035] The specific steps for the workpiece to complete the pre-assembly of the filter in the third pre-assembly station include:

[0036] The workpiece is transported to the third unpowered spindle of the third pre-assembly station on the machine frame. The third moving plate assembly on the machine frame is driven to move upward and embed the partition into the third spring plate assembly on the machine frame. The third spring plate assembly is driven to move directly above the third unpowered spindle and pushes the filter to the workpiece flare position through the cylinder.

[0037] The specific steps for the workpiece to complete the filter pressing in the third pressing station include:

[0038] The workpiece is transported to the third powered spindle of the third pressing station on the machine frame. The third grooving transfer assembly on the machine frame grooves the periphery of the workpiece to form an installation position. The third moving pressing assembly on the machine frame pushes the filter to be pressed into the installation position of the workpiece.

[0039] This application also relates to a six-station fully automatic CNC pressing device for air conditioning liquid receivers, based on the aforementioned six-station fully automatic CNC pressing method for air conditioning liquid receivers, including:

[0040] The frame has multiple pre-assembly stations and pressing stations arranged sequentially at intervals;

[0041] A pre-assembly mechanism is installed at a pre-assembly station. The pre-assembly mechanism includes a first base and a production line assembly, a slide assembly, and a moving plate assembly connected to the first base. A spring plate assembly is connected to one side of the slide assembly above the moving plate assembly. The production line assembly is used to transport the partition to the moving plate assembly, and the moving plate assembly can push the partition to move into the spring plate assembly. The slide assembly can drive the spring plate assembly to move vertically and horizontally, so that the partition is transported to the workpiece flaring position.

[0042] A pressing mechanism is provided at a pressing station; the pressing mechanism includes a second base and a movable pressing component and a grooving and conveying component connected to the second base; the grooving and conveying component is used to groove multiple annular grooves on the periphery of the workpiece to facilitate the formation of mounting positions for installing partitions, and the movable pressing component can drive the partitions to be pressed into the corresponding mounting positions of the workpiece.

[0043] The pre-assembly mechanism of this application enables pre-assembly before pressing, allowing components such as partitions or filters to be precisely positioned before pressing. This ensures that the pre-positioned partitions or filters can be directly and linearly pushed into the liquid reservoir during the pressing process. This avoids misalignment of partitions or filters due to vibration during transport, incorrect placement of partitions or filters during transport leading to assembly errors, and structural defects in the partitions or filters that go undetected, resulting in defective products after pressing. This increases the difficulty of subsequent rework and quality inspection, and in severe cases, leads to product scrapping, reduced output, increased production cycle and costs, and waste of raw materials, among other processing problems. Therefore, this application, by setting up a pre-assembly mechanism, can... It allows for advance preparation for pressing, ensuring a smoother and uninterrupted pressing process, reducing waiting time, increasing production cycle and speed, and improving product quality and pass rate. It achieves a high degree of automation, intelligence, and full-process monitoring, ensuring precise positioning at every stage. The assembly line components facilitate the conveyor transport of partitions, while the moving plate components ensure precise delivery of each partition to the spring plate components. The spring plate components then precisely position each partition or filter. By driving the spring plate components vertically and horizontally to align them directly above the workpiece with the flared position, and using a top cylinder to push the partitions or filters within the spring plate components, the partitions or filters are precisely delivered to the flared position, facilitating a one-click pressing mechanism to insert the partitions into the reservoir's mounting position.

[0044] The assembly line component includes conveyor belts distributed along the length of the first base;

[0045] The slide assembly is positioned above the conveyor belt. The slide assembly includes a first movable slide that moves horizontally and a second movable slide that slides vertically connected to the first movable slide. A spring plate assembly is connected to the outward-facing side of the second movable slide. The spring plate assembly includes a driving component, a fixed disk, and spring plate housings. The fixed disk is connected to the second movable slide, the driving component is connected above the fixed disk, and multiple spring plate housings are circumferentially connected below the fixed disk. A limit groove is formed at the bottom of each spring plate housing. A spring plate is connected to the inward-facing side of each spring plate housing.

[0046] The movable plate assembly includes a drive device connected to the first base and a movable plate connected above the drive device; the movable plate is circumferentially connected with a plurality of baffles corresponding to the limiting grooves. The drive device drives the movable plate to move upward so that the baffles extend into the limiting grooves. The partition or filter can squeeze the spring sheet and be clamped by the elastic force released by the spring sheet.

[0047] The conveyor belt in the assembly line component of this application can effectively transport multiple partitions or filters, so that the partitions or filters are sequentially fed into the moving plate assembly on the other side of the assembly line component. The slide assembly is set above the conveyor belt and includes a first moving slide and a second moving slide. The first moving slide can move horizontally, thereby driving the second moving slide and the spring plate assembly on one side of the second moving slide to move horizontally. The second moving slide can move vertically, thereby driving the spring plate assembly on one side of the second moving slide to move vertically, so that it can be correspondingly set with the moving plate assembly. When the spring plate assembly is above the moving plate assembly, by driving the moving plate in the moving plate assembly to move upward, since the moving plate can be embedded in the limiting groove of the spring plate housing of the spring plate assembly, the partition can be moved into the spring plate connected to the spring plate housing. The spring plate is compressed by the pressure of the partition or filter, and the released reverse elastic force can clamp the periphery of the partition or filter, and the partition or filter is clamped below the fixed plate.

[0048] The present application discloses a six-station fully automatic CNC press-fitting device for an air conditioning liquid receiver, which further includes a first positioning mechanism. The first positioning mechanism is disposed in the pre-assembly station corresponding to the lower part of the pre-assembly mechanism. The first positioning mechanism includes a non-powered spindle connected to the frame. The non-powered spindle includes a base, a connecting component connected above the base, and a pneumatic chuck assembly connected above the connecting component.

[0049] The pneumatic chuck assembly includes an outer chuck seat, an inner chuck seat, and multiple chucks slidably connected to the inner chuck seat. The outer chuck seat has air holes that communicate with the inner chuck seat for gas flow. These air holes correspond to the chucks, allowing airflow to push the chucks to move relative to each other and clamp the workpiece around its periphery. A positioning rod is connected within the connecting assembly; the positioning rod can adjust its height relative to the connecting assembly to adjust the height of the workpiece between the chucks.

[0050] This application establishes a first positioning mechanism corresponding to the pre-assembly mechanism. The unpowered spindle in this first positioning mechanism positions and clamps the workpiece, preventing workpiece tilting or movement and facilitating subsequent pre-assembly. The base of the unpowered spindle is connected to a pneumatic chuck assembly via a connecting component. In practical applications, neither the outer nor inner seat of the pneumatic chuck assembly rotates; only the multiple chucks within the inner seat can move relative to it. This movement is achieved through air holes connecting the outer and inner seats to the outside. External pneumatic equipment supplies gas into these holes, pushing the chucks inward to clamp the workpiece in the center, thus securing it. A positioning rod is located inside the base. Since the positioning rod connects to the connecting component, its height can be adjusted relative to the component. One end of the positioning rod extends into the inner seat of the pneumatic chuck assembly, reaching the bottom of the workpiece. Adjusting the height of the positioning rod allows for adjustment of the workpiece's height, thus adapting to the installation and positioning of liquid reservoirs of different sizes and heights.

[0051] The movable pressing assembly includes a drive mechanism connected above the second base, a pressing rod connected below the drive mechanism, and a pressing head rotatably connected below the pressing rod. The pressing head extends downward into the workpiece through the drive mechanism and rotates with the workpiece.

[0052] The grooving transfer assembly includes a positioning seat connected to the bottom wall of the second base, a sliding seat slidably connected to the top of the positioning seat, and a grooving wheel rotatably connected to the sliding seat; proximity switches are connected to both sides of the positioning seat to detect the limit position of the grooving wheel sliding along the positioning seat; the grooving wheel can groove the circumference of the rotating workpiece.

[0053] This application achieves the following by setting a pressing rod of a movable pressing assembly and a pressing head rotatably connected below the pressing rod: A drive mechanism is connected above the pressing rod, which drives the pressing rod and pressing head to move vertically, thereby adjusting the height of the pressing rod and pressing head so that the pressing head extends into the workpiece and can rotate with the workpiece. This allows the pressing head to follow the workpiece during downward pressing of the partition or filter, achieving a spin-pressing operation. Simultaneously, a grooving transfer assembly also operates, with its sliding seat moving along a fixed path. The seat slides towards the workpiece, causing the grooved wheel to move to the circumference of the workpiece and press it inward, forming multiple annular grooves on the circumference of the workpiece, i.e., the reservoir. This creates multiple annular bosses on the inner circumference of the reservoir. When the pressing head presses down on the partition or filter, it positions the partition or filter above the annular bosses. The bottom surface of the partition or filter and the top surface of the annular bosses form the mounting position for the partition or filter, thus achieving precise positioning of the partition or filter within the reservoir and completing the precise pressing process.

[0054] This application discloses a six-station fully automatic CNC pressing device for an air conditioning liquid receiver, which further includes a second positioning mechanism. The second positioning mechanism includes a powered spindle. The powered spindle includes a base cylinder, an outer sleeve connected above the cylinder, a main spindle disposed inside the outer sleeve, a main spindle connector disposed above the outer sleeve, and a pneumatic rotary chuck assembly disposed above the main spindle connector. The main spindle is connected to the main spindle connector and the base cylinder respectively, and an adjusting rod for adjusting the workpiece height is connected above the main spindle. The pneumatic rotary chuck assembly includes a rotary chuck outer seat, a rotary chuck inner seat connected inside the rotary chuck outer seat, and multiple clamps for clamping the workpiece slidably connected inside the rotary chuck inner seat. The rotary chuck inner seat is connected to the main spindle connector. When the base cylinder drives the main spindle to rotate, the workpiece can be rotated through the main spindle connector, the rotary chuck inner seat, and the clamps to achieve rotary pressing.

[0055] This application incorporates a second positioning mechanism positioned below the pressing mechanism. This second positioning mechanism includes a power spindle capable of rotating the workpiece. The spindle is housed inside the outer casing and connects to a spindle connector. This connector connects to the inner seat of the pneumatic rotary chuck assembly. An adjusting rod is connected to the top of the spindle, allowing for height adjustment relative to the spindle. The adjusting rod contacts the bottom of the workpiece, providing both support and height adjustment. The outer and inner seats of the pneumatic rotary chuck assembly have air vents connecting to the outside. Gas enters the inner seat through the outer seat and impacts the clamps, causing them to grip the workpiece and fix it between multiple clamps. When the base cylinder drives the spindle to rotate, it drives the spindle connector, the inner seat of the rotary chuck, and the clamps to rotate, thus achieving the rotational pressing of the workpiece during the pressing process.

[0056] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0057] The pre-assembly mechanism of this application enables pre-assembly before pressing, allowing components such as partitions or filters to be precisely positioned before pressing. This allows the pre-positioned partitions or filters to be directly pushed into the liquid reservoir during the pressing process, avoiding misalignment of partitions or filters due to vibration during transport, incorrect placement of partitions or filters during transport leading to assembly errors, and structural errors in the partitions or filters that go undetected and result in defective products after pressing. This increases the difficulty of subsequent rework and quality inspection, and in severe cases, leads to product scrapping, reduced output, increased production cycle and production costs, and waste of raw materials, among other processing problems.

[0058] Therefore, this application, by setting a pre-installation mechanism, can prepare for pressing in advance, making the pressing process smoother and more uninterrupted, reducing waiting time, increasing production cycle and speed, and improving product quality and pass rate. It achieves a high degree of automation, intelligence, and full-process monitoring, ensuring that every step is precise. The assembly line component realizes the assembly line transport of the partitions, the moving plate component enables precise transport of each partition to the spring plate component, the spring plate component enables precise positioning of each partition or filter, the driving spring plate component is adjusted vertically and horizontally to be directly above the workpiece and aligned with the flared position, and the top cylinder pushes the partition or filter in the spring plate component to be precisely transported to the flared position, facilitating the subsequent pressing mechanism to press the partition into the installation position of the liquid reservoir with one click. This application involves a pre-assembly operation at the pre-assembly station before the diaphragm or filter is press-fitted. This allows the diaphragm or filter to first enter the flared position of the liquid reservoir, ensuring that the plane of the diaphragm or filter is basically flush with the flared position of the liquid reservoir. This achieves basic alignment of the diaphragm or filter, preventing jamming or damage caused by severe misalignment at the start of the formal press-fitting process. If a problem occurs in any minor step before press-fitting, it can be resolved promptly, avoiding rework after press-fitting. Furthermore, pre-assembly can be performed simultaneously with the corresponding devices at the press-fitting station. For example, while one liquid reservoir is being press-fitted, the next liquid reservoir can be prepared in advance, enabling precise and accurate execution. After pre-assembly, the pre-assembled liquid reservoir is then press-fitted, reducing the waiting time for devices at the press-fitting station, thereby accelerating the production cycle and further improving production efficiency and product quality.

[0085] Example 1

[0086] This application relates to a six-station fully automatic CNC press-fitting method for an air conditioning liquid receiver, the steps of which include:

[0087] S1: Pre-installed partition:

[0088] The workpiece is conveyed to the unpowered spindle 9 of the first pre-assembly station 2 on the frame 1;

[0089] The partition is conveyed to the first moving plate assembly 84 of the first pre-assembly mechanism 8 on the frame 1 by the first assembly line assembly 82. The first slide assembly 83 of the first pre-assembly mechanism 8 drives the first moving plate assembly 84 to move upward to push the partition into the first spring plate assembly 85 of the first pre-assembly mechanism 8. The multiple elastic cards of the first spring plate assembly 85 clamp the partition.

[0090] The first slide assembly 83 drives the first spring plate assembly 85 to move directly above the first unpowered spindle 9, and the cylinder of the first spring plate assembly 85 pushes the partition to fall to the workpiece flaring position.

[0091] S2: Pressing the partition:

[0092] The workpiece is conveyed from the first pre-assembly station 2 to the first powered spindle 11 of the first pressing station 3 on the frame 1;

[0093] The first groove transfer assembly 103 of the pressing mechanism 10 on the frame 1 grooves the periphery of the workpiece, and the first moving pressing assembly 102 of the first pressing mechanism 10 moves down to press the partition into the corresponding installation position of the workpiece.

[0094] S3: Repeat steps S1-S2 so that the workpiece completes the pre-assembly of the second partition in the second pre-assembly station 4 and the press-fitting of the second partition in the second press-fitting station 5.

[0095] S4: Repeat steps S1-S2 so that the filter is pre-assembled in the third pre-assembly station 6 and the filter is press-fitted in the third press-fitting station 7.

[0096] This application presents a six-station fully automated CNC press-fitting method for air conditioning liquid receivers, capable of pre-installing and press-fitting at least two partitions and filters in the liquid receiver. This not only avoids the significant processing errors associated with directly pressing partitions or filters, but also accelerates production cycle time, improves production efficiency, ensures production quality, and increases product qualification rate and quality. During the process of directly pressing partitions into the liquid receiver during transport, vibrations caused by device movement can lead to inaccurate placement angles, even reversed orientation, and inaccurate positioning, resulting in partition skewing or bending. If the support directly presses the partitions downwards into the liquid receiver, it can cause installation errors, leading to a certain scrap rate for components. Furthermore, the partitions themselves may have burrs, bumps, or dimensional errors. If the partitions are directly pressed into the liquid receiver holes to form an interference fit, these issues may not be detected in time. Problems are only discovered during quality inspection after all processes are completed, requiring rework and further reducing production efficiency. Moreover, rework may cause secondary damage to the workpiece. Furthermore, because problems cannot be detected in a timely manner, an error in one step can further affect the quality of the product during subsequent pressing of other components, potentially leading to scrapped products. Moreover, impurities and dust can enter during the pressing process; directly pressing these materials can cause them to be pressed into the reservoir along with the partitions or filters, further contributing to product quality issues.

[0097] Therefore, based on the above considerations, this application will perform a pre-assembly operation at the pre-assembly station before the partition or filter is press-fitted. This allows the partition or filter to first enter the flared position of the liquid reservoir, ensuring that the plane of the partition or filter is flush with the flared position of the liquid reservoir. This achieves basic alignment of the partition or filter, avoiding jamming or damage caused by severe misalignment at the start of the formal press-fitting process. If a problem occurs in any minor step, i.e., before press-fitting, it can be resolved promptly, avoiding rework after press-fitting. Moreover, the multi-station setup allows pre-assembly and press-fitting to be carried out simultaneously. For example, while one liquid reservoir is being press-fitted at the press-fitting station, the next liquid reservoir can be "prepared" for pre-assembly of the press-fitting components, thus achieving advance preparation and precise execution. Each press-fitting component is pre-assembled before the liquid reservoir with the pre-assembled components is press-fitted, reducing the waiting time of the equipment at the press-fitting station, thereby accelerating the production cycle and further improving production efficiency and product quality.

[0098] Furthermore, the specific steps for pre-installing the partitions include:

[0099] S11: The workpiece is transported to the loading position 15 by the robot arm, and the transfer component 12 clamps the workpiece and transports it from the loading position 15 to the first unpowered spindle 9 on the first pre-assembly station 2;

[0100] S12: The partition is conveyed to the first assembly line component 82 of the first pre-assembly mechanism 8 by the elevator, and then conveyed to the first moving plate component 84 of the first pre-assembly mechanism 8 by the first assembly line component 82.

[0101] S13: When the laser beam detection device 17 on the first production line assembly 82 detects that there is a partition on the first moving plate assembly 84, the first slide assembly 83 moves down and drives the first spring plate assembly 85 to move down.

[0102] S14: Drive the first moving plate assembly 84 of the first pre-installation mechanism 8 to move upward to push the partition into the first spring plate assembly 85, and the multiple elastic clips of the first spring plate assembly 85 clamp the partition.

[0103] S15: The first slide assembly 83 of the first pre-installation mechanism 8 moves horizontally to drive the first spring plate assembly 85 to move directly above the first unpowered spindle 9;

[0104] S16: The partition is pushed to the workpiece flaring position by the top cylinder of the first spring plate assembly 85.

[0105] In this application, the pre-assembly of the first partition is performed at the first pre-assembly station 2. The workpiece is first picked up from the loading station 15 and transferred to the first unpowered spindle 9 at the first pre-assembly station 2 by the transfer assembly 12. The purpose of setting the first unpowered spindle 9 is to achieve fixed clamping of the workpiece, preventing it from tilting or rotating. The first partition is then transported sequentially to the first moving plate assembly 84 of the first pre-assembly mechanism 8 via the first assembly line assembly 82. The first moving plate assembly 84 transports the first partition to the first spring plate assembly 85 above it by moving vertically. The first spring plate assembly 85 is connected to the first slide assembly 83, which drives the first spring plate assembly 85 to move horizontally and vertically, thereby aligning the first spring plate assembly 85 with the first moving plate assembly 84 below. This allows the first partition in the first moving plate assembly 84 to be inserted upwards into the first spring plate assembly 85. Specifically, the first moving plate assembly 84 can... The first partition in the first movable plate assembly 84 extends into the first spring plate assembly 85 and firstly extends into the multiple elastic cards, touching the multiple elastic cards of the first spring plate assembly 85. The multiple elastic cards are compressed by the pressure of the first partition. The reverse elastic force released after the multiple elastic cards are compressed can clamp the peripheral side of the first partition, thereby realizing the first partition is embedded into the first elastic plate assembly. Then, the first spring plate assembly 85 is driven by the first slide assembly 83 to move directly above the first unpowered spindle 9. The top cylinder connected to the top of the first spring plate assembly 85 can move downward to push the first partition below to the flared position of the workpiece, thereby realizing the pre-installation of the first partition of the workpiece.

[0106] This application positions and transports the first partition and the workpiece separately. After being conveyed in an assembly line, the first partition needs to be precisely positioned by the cooperation of a dedicated first moving plate assembly 84 and a first spring plate assembly 85. This further prevents the first partition from getting stuck or being inaccurately positioned during transportation. It can accurately capture each partition and effectively clamp and position each partition, so that the first partition is positioned correctly above each workpiece. The cylinder at the top of the first spring plate assembly 85 performs the final push, allowing the first partition to fall downwards from its precisely positioned position into the flared position of the workpiece. The first spring plate assembly 85 can be moved up and down and horizontally by the first slide assembly 83. Therefore, the distance between the first partition and the workpiece is small, and there will not be a large falling distance. Moreover, during the process of pushing the first partition, the top cylinder will contact the first partition and push it at a constant speed until the first partition is pushed to the flared position of the workpiece.

[0107] Furthermore, the specific steps for pressing the partition include:

[0108] S21: The workpiece is transported from the first pre-assembly station 2 to the first powered spindle 11 of the first pressing station 3 by the transfer assembly 12;

[0109] S22: Grooving is performed on the periphery of the workpiece by the grooving transfer assembly 103 of the first pressing mechanism 10, so that multiple partition mounting positions are formed on the inner wall of the workpiece along the axial direction. At the same time, the moving pressing assembly 102 of the first pressing mechanism 10 moves down to press the partitions into the corresponding mounting positions on the inner wall of the workpiece.

[0110] The workpiece is conveyed from the first pre-assembly station 2 to the powered spindle of the first pressing station 3 via the transfer assembly 12. The powered spindle can drive the rotation of the workpiece because, during the pressing process, the partition needs to be pressed into the rotating liquid reservoir to achieve a spin pressing operation. The purpose of this spin pressing is to ensure that the partition can be installed flat, smoothly, and without damage, while also ensuring the sealing and assembly quality between the partition and the inner wall of the tank. Furthermore, the partition is usually a metal disc with a rubber sealing ring, and its diameter is slightly larger than the inner diameter of the liquid reservoir. Therefore, the partition and the workpiece have an interference fit. If the partition is pressed into the tank directly in a straight line, it is very easy for it to tilt due to the large friction. Once tilting begins, the pressing resistance will increase sharply, causing the edge of the partition to curl or deform, scratching the inner wall of the tank, damaging the smoothness of the inner wall, affecting subsequent sealing, and even generating metal fragments. It also further causes equipment overload: the pressing equipment needs to output greater pressure, which may cause damage. This application employs a first powered spindle to rotate the workpiece. Simultaneously, this rotation of the workpiece also provides rotational power to the pressing head in the upper first pressing mechanism, allowing the partition to be rotated and pressed into the workpiece. This rotational pressing is equivalent to applying a "torsional force" and a "grinding" action to the partition. This rotational force helps correct minor tilts, allowing the partition to automatically "align" itself, ensuring it always enters the can with the most even force. It's much easier and smoother than simply pressing down on a bottle cap.

[0111] Therefore, the reservoir needs to be rotated in the first pressing station 3. The first powered spindle 11 can not only clamp and position the workpiece, but also rotate the workpiece and adjust the height of the workpiece to adapt to different processing requirements. While pressing the first partition into the reservoir, in order to achieve precise positioning and installation of the first partition in the reservoir, the first grooving transfer assembly 103 needs to press the workpiece inward from the periphery, forming an annular boss on the inner side of the workpiece and an annular groove on the outer side of the workpiece. That is, grooving is achieved on the periphery of the workpiece, so that the inside of the reservoir has an inward radial boss corresponding to the grooving position. At the same time, the first moving pressing assembly 102 is moved down, and a certain downward pressure is applied to the first partition located at the flared position so that it is pressed into the top of the boss. The top surface of the boss abuts against the bottom surface of the first partition, thereby achieving the pressing and positioning of the first partition, and thus achieving the pressing of the first partition into the reservoir to form an interference fit with the reservoir.

[0112] Furthermore, the specific steps for the pre-assembly of the second partition plate in the second pre-assembly station 4 include:

[0113] The workpiece is transported to the second unpowered spindle 9 of the second pre-assembly station 4 on the frame 1. The second moving plate assembly 84 on the frame 1 is driven to move upward and embed the second partition into the second spring plate assembly 85 on the frame 1. The second spring plate assembly 85 is driven to move directly above the second unpowered spindle 9 and the second partition is pushed to the workpiece flaring position by the cylinder.

[0114] The second pre-assembly station 4 in this application has the same structural layout and working principle as the first pre-assembly station 2; its purpose is to complete the pre-assembly of the second partition, which will not be elaborated on here.

[0115] Furthermore, the specific steps for pressing the second partition plate onto the workpiece at the second pressing station 5 include:

[0116] The workpiece is transported to the second powered spindle 11 of the second pressing station 5 on the frame 1. The second grooving transfer assembly 103 on the frame 1 grooves the periphery of the workpiece to form an installation position. The second moving pressing assembly 102 on the frame 1 pushes the second partition plate to press into the installation position of the workpiece.

[0117] The second pressing station 5 in this application has the same structural layout and working principle as the first pressing station 3; however, it is only for pressing the second partition plate, so it will not be described in detail here.

[0118] Furthermore, the specific steps for pre-assembling the filter in the third pre-assembly station 6 include:

[0119] The workpiece is transported to the third unpowered spindle 9 of the third pre-assembly station 6 on the frame 1. The third moving plate assembly 84 on the frame 1 is driven to move upward, and the second partition is embedded into the third spring plate assembly 85 on the frame 1. The third spring plate assembly 85 is driven to move directly above the third unpowered spindle 9, and the filter is pushed to the workpiece flare position by the cylinder.

[0120] The third pre-assembly station 6 in this application has the same structural layout and working principle as the first pre-assembly station 2; its purpose is to complete the pre-assembly of the filter, which will not be elaborated on here.

[0121] Furthermore, the specific steps for pressing the filter into place within the third pressing station 7 include:

[0122] The workpiece is transported to the third powered spindle 11 of the third pressing station 7 on the frame 1. The third grooving transfer assembly 103 on the frame 1 grooves the periphery of the workpiece to form an installation position. The filter is pushed and pressed into the installation position of the workpiece by the third moving pressing assembly 102 on the frame 1.

[0123] The third pressing station 7 in this application has the same structural layout and working principle as the first pressing station 3; the difference is that the third pressing mechanism is used to press the filter, which will not be described in detail here.

[0124] Example 2

[0125] This application also relates to a six-station fully automatic CNC pressing device for air conditioning liquid receivers, such as... Figure 1-10 As shown, a six-station fully automatic CNC press-fitting method for an air conditioning liquid receiver, as described above, includes:

[0126] The frame 1 has multiple pre-assembly stations and pressing stations arranged sequentially at intervals;

[0127] A pre-assembly mechanism 8 is installed at a pre-assembly station. The pre-assembly mechanism 8 includes a first base 81 and a production line assembly 82, a slide assembly 83, and a moving plate assembly 84 connected to the first base 81. A spring plate assembly 85 is connected to one side of the slide assembly 83 above the moving plate assembly 84. The production line assembly 82 is used to transport the partition to the moving plate assembly 84, and the moving plate assembly 84 can push the partition to move into the spring plate assembly 85. The slide assembly 83 can drive the spring plate assembly 85 to move vertically and horizontally, so that the partition is transported to the workpiece flaring position.

[0128] The pressing mechanism 10 is located at the pressing station. The pressing mechanism 10 includes a second base 101 and a movable pressing assembly 102 and a grooving and transfer assembly 103 connected to the second base 101. The grooving and transfer assembly 103 is used to groove a plurality of annular grooves on the periphery of the workpiece to facilitate the formation of mounting positions for mounting partitions. The movable pressing assembly 102 can drive the partitions to be pressed into the corresponding mounting positions of the workpiece.

[0129] The pre-assembly mechanism 8 of this application enables pre-assembly before pressing, positioning components such as partitions or filters precisely in their corresponding positions before pressing. This allows the pre-positioned partitions or filters to be directly and linearly pushed into the liquid reservoir during the pressing process. This avoids issues such as misalignment of partitions or filters due to vibration during transport, incorrect placement of partitions or filters during transport leading to assembly errors, and undetected structural errors in the partitions or filters resulting in defective products after pressing. These issues increase the difficulty of subsequent rework and quality inspection, and in severe cases, lead to product scrapping, reduced output, increased production cycle and costs, and waste of raw materials. Therefore, by setting up the pre-assembly mechanism 8, this application can prepare for pressing in advance, making the pressing process smoother and uninterrupted, reducing waiting time, increasing production cycle and speed, improving product quality and yield, achieving a high degree of automation, intelligence, and full-process monitoring, and ensuring precise positioning at every stage. The assembly line component 82 enables the continuous conveying of the partitions. The moving plate component 84 ensures precise delivery of each partition to the spring plate component 85. The spring plate component 85 precisely positions each partition or filter. By driving the spring plate component 85 vertically and horizontally, it is aligned directly above the workpiece with the flared position. A top cylinder pushes the partition or filter in the spring plate component 85, precisely delivering it to the flared position. This facilitates the subsequent pressing mechanism 10 to press the partition into the installation position of the liquid reservoir with a single click. Figure 11 The diagram shown is a side view of the cross-section of the reservoir 18 after the pre-installation and pressing of the first partition, the pre-installation and pressing of the second partition, and the pre-installation and pressing of the filter. The first partition 19 is located at the bottom of the reservoir, the second partition 20 is located between the first partition and the filter, and the filter 21 is pressed onto the top of the reservoir 18.

The multiple pressing stations mentioned herein include, but are not limited to, the first pressing station 3, the second pressing station 5, and the third pressing station 7. The first pre-assembly station 2, the second pre-assembly station 4, and the third pre-assembly station 6 mentioned in the method have the same structure. The first pressing station 3, the second pressing station 5, and the third pressing station 7 have the same structure. That is, the first pre-assembly mechanism 8 in the first pre-assembly station, the second pre-assembly mechanism 8 in the second pre-assembly station, and the third pre-assembly mechanism 8 in the third pre-assembly station have the same structure. The first pressing mechanism 10 in the first pressing station, the second pressing mechanism 10 in the second pressing station, and the third pressing mechanism 10 in the third pressing station have the same structure.

[0131] Specifically, such as Figure 1 and Figure 2 As shown, a transfer assembly 12 is connected to one side of the frame 1 along its length. On the side of the frame 1 connected to the transfer assembly 12, a first pre-assembly station 2, a first pressing station 3, a second pre-assembly station 4, a second pressing station 5, a third pre-assembly station 6, and a third pressing station 7 are sequentially arranged along the length of the frame 1.

Specifically,

[0132] The first pre-assembly station 2 is connected to a first positioning mechanism and a first pre-assembly mechanism 8. The first positioning mechanism is used to clamp the workpiece, and the first pre-assembly mechanism 8 is used to pre-assemble the first partition in the workpiece by placing the first partition at the flared part of the workpiece.

[0133] The second pre-assembly station 4 is connected to a first positioning mechanism and a second pre-assembly mechanism 8. The first positioning mechanism is used to clamp the workpiece, and the second pre-assembly mechanism 8 is used to pre-assemble the second partition in the workpiece by placing the second partition at the flared end of the workpiece.

[0134] The third pre-assembly station 6 is connected to the first positioning mechanism and the third pre-assembly mechanism 8. The first positioning mechanism is used to clamp the workpiece, and the second pre-assembly mechanism 8 is used to pre-assemble the filter in the workpiece by placing the filter at the flared part of the workpiece.

[0135] The first pressing station 3 is connected to a second positioning mechanism and a first pressing mechanism 10. The second positioning mechanism is used to clamp the workpiece and realize the rotation of the workpiece, which is conducive to realizing rotational pressing. The first pressing mechanism 10 is used to rotate and press the first partition located at the flared position into the workpiece to realize pressing.

[0136] The second pressing station 5 is connected to a second positioning mechanism and a second pressing mechanism 10. The second positioning mechanism is used to clamp the workpiece and realize the rotation of the workpiece, which is conducive to realizing rotational pressing. The second pressing mechanism 10 is used to rotate and press the second partition located at the flared position into the workpiece to realize pressing.

[0137] The third pressing station 7 is connected to a second positioning mechanism and a third pressing mechanism 10. The second positioning mechanism is used to clamp the workpiece and realize the rotation of the workpiece, which is conducive to realizing rotational pressing. The third pressing mechanism 10 is used to rotate and press the filter located at the flared position into the workpiece to realize pressing.

[0138] For the sake of brevity, and since the first pre-assembly mechanism 8, the second pre-assembly mechanism 8, and the third pre-assembly mechanism 8 have the same structure, the first pre-assembly mechanism 8, the second pre-assembly mechanism 8, and the third pre-assembly mechanism 8 in the first pre-assembly station 2, the second pre-assembly station 4, and the third pre-assembly station 6 are collectively referred to as pre-assembly mechanism 8. Similarly, the first pressing mechanism 10 in the first pressing station 3, the second pressing mechanism 10 in the second pressing station 5, and the third pressing mechanism 10 in the third pressing station 7 are collectively referred to as pressing mechanism 10. A detailed description of the entire device is as follows:

[0139] Furthermore, the transfer assembly 12 includes a transfer table 121 slidably connected to a track on the frame 1. A fixed platform 122 is connected above the transfer table 121. A movable platform 123 is connected to the side of the fixed platform 122 facing the pre-assembly station of the frame 1. A cylinder is connected to the top of the fixed platform 122. The movable platform 123 is connected to the bottom of the cylinder, which can drive the movable platform 123 to move up and down. The movable platform 123 includes a central support distributed along the length direction of the frame 1. The side of the central support facing the pre-assembly station has multiple equally spaced gripping assemblies. The gripping assembly includes a linear cylinder 131, a gripping positioning seat 1031, and two grippers rotatably connected to the gripping positioning seat 1031. Each gripper 133 is rotatably connected to the gripper positioning seat 132 via a rotating shaft. The rotating shaft connected to each gripper 133 has a first gear. The linear cylinder 131 is connected to a rack, which has teeth on both sides. The rack is connected to the gripper positioning seat 132 and can mesh with the first gear. Therefore, when the linear cylinder 131 drives the rack to move linearly, it can drive the first gear to rotate, thereby causing the grippers 133 on both sides to rotate relative to each other, thus setting the opening and closing angle of the grippers 133 to adapt to clamping liquid reservoirs of different sizes. The transfer table 121 moves along the length of the frame 1, and can move vertically under the drive of the cylinder, thereby realizing the horizontal and vertical movement of the gripper assembly 13 to install the workpiece in different pre-assembly and pressing positions.

[0140] like Figure 3The diagram shows a pre-assembly mechanism 8, which includes a first base 81 connected to the frame 1 and a conveyor assembly 82, a slide assembly 83, and a moving plate assembly 84 connected to the first base 81. Figure 3 As shown, a conveyor assembly 82 is connected to the first base 81. The conveyor assembly 82 includes a conveyor belt distributed along the length direction of the first base 81. The conveyor assembly 82 is used to convey the partition to the moving plate assembly 84.

[0141] Furthermore, the slide assembly 83 is disposed above the conveyor belt. The slide assembly 83 includes a first movable slide 831 that moves horizontally and a second movable slide 832 that slides vertically connected to the first movable slide 831. The first movable slide 831 moves horizontally and includes a first drive cylinder and a first movable slide body connected to one side of the first drive cylinder. The bottom of the first movable slide body is slidably connected to the track of the first base 81 by a slider.

[0142] When the first drive cylinder is activated, it can push the first movable slide body to slide along the first base 81; the second movable slide 832 includes a fixed bracket 8321, a movable slide plate 8322, and a slide plate bracket 8323; the fixed bracket 8321 is connected to the top of the first movable slide body, the movable slide plate 8322 has a slider that can slide and connect with the slide rail on the fixed bracket 8321, the slide rail is arranged vertically, so that the movable slide plate 8322 can move vertically, and the slide plate bracket 8323 is connected to one side of the movable slide plate 8322. On the side, the slide bracket 8323 can move vertically under the drive of the movable slide 8322; the slide bracket 8323 has a positioning platform in the horizontal direction, and a spring plate assembly 85 is connected in the positioning platform. The first base 81 is connected to the movable plate assembly 84 at the end of the conveyor belt. The spring plate assembly 85 is set above the movable plate assembly 84. The spring plate assembly 85 can move vertically or horizontally under the drive of the slide assembly 83, and move the spring plate assembly 85 to a preset height position directly above the movable plate assembly 84.

[0143] Furthermore, the spring plate assembly 85 includes a drive member 851, a fixed plate 852, and a spring plate housing 853; the fixed plate 852 is connected to the second movable slide 832, the drive member 851 is connected above the fixed plate 852, and a plurality of spring plate housings 853 are circumferentially connected below the fixed plate 852; a limiting groove is formed at the bottom of the spring plate housing 853; a spring plate is connected to the inward side of the spring plate housing 853.

[0144] like Figure 4As shown, the fixed plate 852 is connected to the positioning platform on one side of the sliding bracket and is fixedly connected to the positioning platform. The fixed plate 852 has a circular structure with a cavity in the middle. The top of the fixed plate 852 is connected to a driving component 851, which is preferably a cylinder. Multiple spring plate housings 853 are fixedly connected to the bottom of the fixed plate 852 along the circumference. The bottom of the multiple spring plate housings 853 has a limiting groove. The function of this limiting groove is to be able to insert and cooperate with the baffle 14 on the periphery of the moving plate 842 of the moving plate assembly 84, so that the baffle 14 can be embedded in the limiting groove during the upward movement of the moving plate 842. A spring plate is connected to the inward side of the spring plate housing 853.

[0145] Furthermore, the movable plate assembly 84 includes a drive device 841 connected to the first base 81 and a movable plate 842 connected above the drive device 841; the movable plate 842 is circumferentially connected with a plurality of baffles 14 corresponding to the limiting grooves. The drive device 841 drives the movable plate 842 to move upward so that the baffles 14 extend into the limiting grooves. The partition or filter can squeeze the spring sheet and be clamped by the elastic force released by the spring sheet; the movable plate assembly 84 can push the partition to move into the spring sheet assembly 85; the slide assembly 83 can drive the spring sheet assembly 85 to move vertically and horizontally so that the partition is conveyed to the workpiece flaring position.

[0146] The conveyor belt in the assembly line component 82 of this application can effectively transport multiple partitions or filters, so that the partitions or filters are sequentially fed into the movable plate assembly 84 on the other side of the assembly line component 82. The slide assembly 83 is disposed above the conveyor belt. The slide assembly 83 includes a first movable slide 831 and a second movable slide 832. The first movable slide 831 can move horizontally, thereby driving the second movable slide 832 and the spring plate assembly 85 on one side of the second movable slide 832 to move horizontally. The second movable slide 832 can move vertically, thereby driving the second movable slide 832 to move horizontally. The spring plate assembly 85 on one side of 32 can move vertically and be positioned corresponding to the movable plate assembly 84. When the spring plate assembly 85 is above the movable plate assembly 84, the movable plate 842 in the movable plate assembly 84 is driven to move upward. Since the movable plate 842 can be embedded in the limiting groove of the spring plate housing 853 of the spring plate assembly 85, the partition can be moved into the spring plate connected to the spring plate housing 853. The spring plate is compressed by the partition or filter, and the released reverse elastic force can clamp the periphery of the partition or filter. The partition or filter is clamped below the fixed plate 852.

[0147] Furthermore, the six-station fully automatic CNC pressing device for air conditioning liquid receiver of this application also includes a first positioning mechanism; the first positioning mechanism includes a non-powered spindle 9 connected to the frame 1; the non-powered spindle 9 includes a base 91, a connecting component 92 connected above the base 91 and a pneumatic chuck assembly 93 connected above the connecting component 92.

[0148] like Figure 5-6 As shown, the pneumatic chuck assembly 93 includes an outer chuck seat 931, an inner chuck seat 932, and multiple chucks 933 slidably connected to the inner chuck seat 932. The outer chuck seat 931 has air holes communicating with the inner chuck seat 932 for gas flow. The air holes correspond to the chucks 933 so that airflow can push the chucks 933 to move relative to each other, thereby clamping the workpiece around its periphery. A positioning rod 94 is connected within the connecting assembly 92. The positioning rod 94 can be height-adjusted relative to the connecting assembly 92 to adjust the height of the workpiece between the chucks 933. Preferably, the positioning rod 94 is threaded into the connecting assembly 92, and one end of the positioning rod 94 can extend into the inner chuck seat 932 to support the bottom of the workpiece.

[0149] This application establishes a first positioning mechanism corresponding to the pre-assembly mechanism 8. The unpowered spindle 9 in the first positioning mechanism positions and clamps the workpiece, preventing it from tilting or moving and facilitating subsequent pre-assembly. The base 91 of the unpowered spindle 9 is connected to a pneumatic chuck assembly 93 via a connecting component 92. In practical applications, the outer seat of the pneumatic chuck assembly 93 does not rotate, nor does the inner seat 932. Only the multiple chucks 933 within the inner seat 932 can move relative to it. The movement is achieved through air holes connecting the outer seat 931 and the inner seat 932 to the outside. Gas is supplied to these holes by an external pneumatic device, pushing the chucks 933 inward to clamp the workpiece between them, thus fixing the workpiece. The positioning rod 94 is provided inside the base 91. Since the positioning rod 94 can be connected to the connecting component 92, the positioning rod 94 can be adjusted in height relative to the connecting component 92. One end of the positioning rod 94 can extend into the chuck inner seat 932 of the pneumatic chuck assembly 93, so it can contact the bottom of the workpiece. Therefore, when the height of the positioning rod 94 is adjusted, the height of the workpiece can be adjusted, thereby adapting to the installation and positioning of liquid reservoirs of different sizes and heights.

[0150] Furthermore, such as Figure 7As shown, the movable pressing assembly 102 includes a drive mechanism 1021 connected above the second base 101, a pressing rod 1022 connected below the drive mechanism 1021, and a pressing head 1023 rotatably connected below the pressing rod 1022. The pressing head 1023 extends downward into the workpiece via the drive mechanism 1021 and rotates with the workpiece. The top of the pressing head 1023 is rotatably connected to the bottom of the pressing rod 1022 via a bearing. The top of the pressing rod 1022 is provided with a fixing plate connected to the bottom of the drive mechanism 1021. The drive mechanism 1021 is connected to the top of the second base 101. A groove transfer assembly 103 is also connected to the inner bottom wall of the second base 101.

[0151] Furthermore, such as Figure 8 As shown, the grooving transfer assembly 103 includes a positioning seat 1031 connected to the bottom wall of the second base 101, a sliding seat 1032 slidably connected to the upper part of the positioning seat 1031, and a grooving wheel 1033 rotatably connected to the sliding seat 1032; proximity switches are connected to both sides of the positioning seat 1031 to detect the extreme position of the grooving wheel 1033 sliding along the positioning seat 1031; the grooving wheel 1033 can groove the circumference of the rotating workpiece.

[0152] This application achieves the following by setting a pressing rod 1022 of a movable pressing assembly 102 and a pressing head 1023 rotatably connected below the pressing rod 1022: the pressing rod 1022 is connected to a driving mechanism 1021 above it. The driving mechanism 1021 can drive the pressing rod 1022 and the pressing head 1023 to move vertically, thereby adjusting the height of the pressing rod 1022 and the pressing head 1023 so that the pressing head 1023 can extend into the interior of the workpiece and rotate with it. This allows the pressing head 1023 to follow the workpiece when pressing it down into the partition or filter to perform a spin pressing operation. While pressing, the grooving transfer assembly 103 is also in operation. The sliding seat 1032 of the grooving transfer assembly 103 can slide along the positioning seat 1031 toward the workpiece side, so that the grooving wheel 1033 moves to the periphery of the workpiece and squeezes the periphery of the workpiece inward, so that multiple annular grooves are formed on the periphery of the workpiece, i.e., the liquid reservoir, thereby forming multiple annular bosses on the inner periphery of the liquid reservoir. When the pressing head 1023 presses down into the partition or filter, it can position the partition or filter above the annular bosses. The bottom surface of the partition or filter and the top surface of the annular bosses form the mounting position for the partition or filter, thereby achieving precise positioning of the partition or filter in the liquid reservoir and completing the precise pressing process. In addition, proximity switches are connected to both sides of the positioning seat 1031 to detect the extreme position of the grooved wheel 1033 sliding along the positioning seat 1031, prevent the grooved wheel 1033 from moving excessively, and achieve precise positioning of the grooved wheel 1033.

[0153] Furthermore, the six-station fully automatic CNC press-fitting device for an air conditioning liquid receiver of this application also includes a second positioning mechanism, which includes a powered spindle 11.

[0154] like Figure 9-10 As shown, the powered spindle 11 includes a base cylinder 111, an outer sleeve 112 connected above the cylinder, a spindle 113 disposed inside the outer sleeve 112, a spindle connector 114 disposed above the outer sleeve 112, and a pneumatic rotary chuck assembly 115 disposed above the spindle connector 114; the lower part of the spindle 113 is connected to the base cylinder 111, and the upper part of the spindle 113 is connected to an adjusting rod 116 for adjusting the workpiece height; the upper part of the spindle 113 is also connected to the spindle connector 114.

[0155] Furthermore, the pneumatic rotary chuck assembly 115 includes a rotary chuck outer seat 931 disposed above the spindle connector 114, a rotary chuck inner seat 1152 connected inside the rotary chuck outer seat 931, and a plurality of clamps 1153 slidably connected within the rotary chuck inner seat 1152 for clamping workpieces. The rotary chuck inner seat 1152 is connected to the spindle connector 114. When the base cylinder 111 drives the spindle 113 to rotate, the spindle connector 114, the rotary chuck inner seat 1152, and the clamps 1153 can rotate, thereby driving the workpiece to rotate to facilitate rotary pressing.

[0156] This application places the second positioning mechanism below the pressing mechanism 10. The second positioning mechanism includes a power spindle 11, which can drive the workpiece to rotate. The spindle 113 is located inside the outer sleeve 112 and can be connected to the spindle connector 114. The spindle connector 114 is connected to the rotary chuck inner seat 1152 of the pneumatic rotary chuck assembly 115. An adjusting rod 116 is also connected to the top of the spindle 113. The adjusting rod 116 can adjust the height relative to the spindle 113. The adjusting rod 116 can contact the bottom of the workpiece, thus both supporting the workpiece and adjusting its height. The pneumatic rotary chuck assembly 115 has an outer rotary chuck seat 931 and an inner rotary chuck seat 1152 with air holes that communicate with the outside. Gas enters the inner rotary chuck seat 1152 through the outer rotary chuck seat 931 and impacts the clamps 1153 on the inner rotary chuck seat 1152, thereby pushing the clamps 1153 to clamp the workpiece, so that the workpiece is fixed between multiple clamps 1153, thereby achieving workpiece fixation. When the base cylinder 111 drives the spindle 113 to rotate, it drives the spindle connector 114, the inner rotary chuck seat 1152 and multiple clamps 1153 to rotate, thereby realizing the rotational pressing of the workpiece during the pressing process.
