Description

Technical Field

[0001] This solution belongs to the technical field of sintered cotton pressing equipment, specifically involving an automatic pressing equipment for sintered cotton. Background Technology

[0002] Sintered cotton is a porous functional material (common substrates are metals, ceramics, etc.) made by powder pressing and high-temperature sintering. With its high porosity, corrosion resistance, high temperature resistance and controllable fluid permeation interception ability, it is often used in industry for fluid filtration, sealing buffering, homogenization and dispersion.

[0003] As per the instruction manual Figure 1 As shown, connectors (including single and multiple sets) are used for connecting pipelines and regulating gas flow. However, in actual industrial applications, the transmitted gas often contains tiny solid particles, which can easily cause wear, scratches, or even blockages to the precision structures inside the connector, such as the valve core and sealing surfaces. Therefore, sintered cotton needs to be installed in the connector's mounting position to intercept impurities in the gas and prevent them from entering downstream pipelines and subsequent equipment.

[0004] When installing sintered cotton in the joint, the existing method involves workers using pliers, tweezers, and other tools to pick up individual pieces of sintered cotton and then aligning them one by one with the installation position of the joint for initial positioning. This method is not only extremely inefficient, but also prone to problems such as displacement and skewness in the installation position of the sintered cotton in the joint due to the influence of the precision and skill of manual operation. Summary of the Invention

[0005] This invention provides an automatic pressing and sintering cotton equipment to solve the problem of automatic installation of sintering cotton at the joint.

[0006] This invention provides an automatic pressing and fitting device for sintered cotton, comprising a frame. Along the material flow direction, a joint feeding device, a sintered cotton feeding device, a transfer device, and a pressing device are sequentially arranged on the frame. The joint feeding device and the sintered cotton feeding device are respectively used to convey the joint and the sintered cotton to the transfer device. The transfer device includes a joint transfer assembly and a sintered cotton transfer assembly mounted on the frame. The joint transfer assembly moves the joint along the frame to the joint pressing station, and the sintered cotton transfer assembly moves the sintered cotton along the frame to the sintered cotton pressing station, aligning the sintered cotton with the installation position of the joint. The pressing device is located directly above the sintered cotton pressing station and applies axial pressure to the sintered cotton, pressing it into the installation position of the joint.

[0007] The principle and effect of this solution are as follows: the joint feeding device and the sintered cotton feeding device automatically feed the joints and sintered cotton respectively, eliminating the need for manual hand-held tools to handle the material. Then, the joint transfer component in the transfer device receives the joint and moves it to the preset joint pressing station. At the same time, the sintered cotton transfer component simultaneously receives the sintered cotton and transfers it to the corresponding sintered cotton pressing station, ensuring alignment with the joint's installation position and avoiding deviations that easily occur during manual alignment. Finally, the pressing device applies axial pressure directly above the sintered cotton pressing station, pressing the sintered cotton into the joint's installation position. This solution simplifies the manual operation process through the above structure, eliminating the need for manual alignment, placement, and preliminary positioning, improving work efficiency, and avoiding problems such as sintered cotton breakage, deformation, or insecure positioning caused by uneven manual pressing force.

[0008] Furthermore, the joint feeding device includes a joint hopper and a vibrating feed hopper. The joint hopper is mounted on the frame. One end of the vibrating feed hopper is connected to the outlet of the joint hopper, and the free end extends to the joint pressing station. The outlet end of the vibrating feed hopper is equipped with a first sensor for detecting the joint.

[0009] The principle and effect of this solution are as follows: the connector hopper pre-stores connectors to be processed, avoiding frequent manual replenishment. During operation, the vibration of the vibrating hopper drives the connectors to be sorted and conveyed along its internal track, so that the connectors are conveyed to the designated position. The first sensor is used to detect whether the connectors at the discharge end are in place, and can coordinate with the subsequent transfer components when the connectors are detected to be in place.

[0010] Furthermore, the sintered cotton feeding device includes a sintered cotton hopper and a vibrating feeder. The sintered cotton hopper is mounted on the frame. One end of the vibrating feeder is connected to the outlet of the sintered cotton hopper, and the free end extends to the sintered cotton pressing station. The outlet end of the vibrating feeder is equipped with a second sensor for detecting the sintered cotton. The vibrating feeder is equipped with multiple feeding troughs arranged along its length, and the outlet end of the vibrating feeder is equipped with a baffle that cooperates with the multiple feeding troughs. The baffle is equipped with a block for blocking the feeding troughs.

[0011] The principle and effect of this solution are as follows: the sintered cotton hopper is used to pre-store sintered cotton, reducing the need for frequent manual replenishment. During operation, the vibration of the vibrating feeder drives the sintered cotton to be oriented and conveyed along its internal track. Since the joints in this application have different models, including single and multiple sets, when the sintered cotton is conveyed to the vibrating feeder, it moves synchronously into multiple feeding slots. The corresponding feeding slot is blocked by the baffle. When different models of joints are selected for processing, the corresponding feeding slot is blocked by the baffle. When the sintered cotton is conveyed to the discharge end of the vibrating feeder, the arrival status of the sintered cotton is detected by the second sensor, thereby connecting the operation of the subsequent transfer components.

[0012] Furthermore, the joint transfer assembly includes a joint transfer cylinder and a support platform. The joint transfer cylinder is mounted on the frame via a bracket. The support platform is fixedly connected to the piston rod of the joint transfer cylinder. The joint pressing station is located on the support platform and is situated on one side of the discharge end of the vibrating hopper. The joint pressing station is equipped with a third sensor for detecting the joint. The third sensor is electrically connected to the transfer cylinder. The piston rod of the joint transfer cylinder extends towards the pressing device and is used to drive the joint pressing station to move below the pressing device.

[0013] The principle and effect of this solution are as follows: the joint pressing station is adjacent to the discharge end of the vibrating feed hopper and can receive joints. The third sensor can detect whether the joint is in place at the joint pressing station. Its detection signal can control the action of the joint transfer cylinder. Only after the joint is in place, the piston rod of the joint transfer cylinder is extended, driving the joint bearing platform to move towards the pressing device, so that the joint pressing station moves to the bottom of the pressing device to cooperate with the subsequent pressing process.

[0014] Furthermore, the sintered cotton transfer assembly includes a sintered cotton transfer cylinder and a support plate. The sintered cotton transfer cylinder is mounted on the frame via a bracket, and the support plate is positioned above the support platform. The support plate is fixedly connected to the piston rod of the sintered cotton transfer cylinder. The sintered cotton pressing station is located on the support plate and is situated on the discharge end side of the vibrating feed hopper. The second sensor is electrically connected to the sintered cotton transfer cylinder. The piston rod of the sintered cotton transfer cylinder faces the pressing device and is used to drive the sintered cotton pressing station to move below the pressing device and directly above the joint pressing station. The support plate is provided with a limiting plate and a limiting cylinder. The limiting plate is located at the bottom of the support plate and is used to block the sintered cotton pressing station. The piston rod of the limiting cylinder is fixedly connected to the limiting plate and is used to drive the limiting plate away from the sintered cotton pressing station.

[0015] The principle and effect of this scheme are as follows: the sintered cotton pressing station is a through-hole sintered cotton pressing station. When the piston rod of the limiting cylinder is in the retracted state, the bottom of the sintered cotton pressing station is blocked by the limiting plate. The sintered cotton pressing station is adjacent to the discharge end of the vibrating feed hopper and can receive sintered cotton. The second sensor is used to detect whether the sintered cotton is in the sintered cotton pressing station. After it is in place, the piston rod of the sintered cotton transfer cylinder is controlled to extend, driving the bearing plate, the limiting plate and the limiting cylinder to move towards the pressing device. The sintered cotton pressing station is located below the pressing device and directly above the joint pressing station. When the pressing device is pressing, the piston rod of the limiting cylinder is controlled to extend, and then the sintered cotton is pressed into the joint.

[0016] Furthermore, the pressing device includes a pressing frame, a pressing cylinder, a pressing head, and a support platform. The pressing frame is mounted on the frame, the pressing cylinder is mounted on the pressing frame, the piston rod of the pressing cylinder is fixedly connected to the support platform, the pressing head is mounted on the support platform, and the pressing head is positioned directly above the sintered cotton pressing station. The shape of the pressing head matches the installation position of the joint.

[0017] The principle and effect of this solution are as follows: After the sintered cotton and the joint are coaxially aligned, the pressing cylinder drives the piston rod to extend, which in turn drives the pressing head to act on the surface of the sintered cotton and apply stable axial pressure. Since the pressing head is a contour pressing head that matches the shape of the joint installation position, it can guide the sintered cotton to be embedded in the installation position of the joint, avoiding the assembly offset and skewing problems that are easy to occur in manual pressing, and avoiding the damage and deformation of the sintered cotton.

[0018] Furthermore, the pressing device also includes a vacuum pump, and the pressing head is a hollow pressing head, one end of which is connected to the vacuum pump through a pipe.

[0019] The principle and effect of this solution are as follows: Since sintered cotton is a porous functional material, it is relatively soft and lacks rigidity. Without temporary fixation, if the pressing head directly presses the sintered cotton, it is prone to displacement, wrinkling, or even damage. Therefore, this solution uses a vacuum pump to provide negative pressure to the pressing head. The piston rod of the pressing cylinder extends a certain distance, allowing the pressing head to contact the sintered cotton. At this point, the vacuum pump activates, generating negative pressure that firmly adheres the sintered cotton to its end face through the hollow pressing head, thus fixing the sintered cotton. Then, the piston rod of the limiting cylinder extends, ensuring that the sintered cotton and the joint mounting position are not obstructed axially. Finally, the piston rod of the pressing cylinder continues to extend, smoothly pressing the sintered cotton into the joint mounting position, avoiding the displacement and skewing problems that easily occur during sintered cotton pressing.

[0020] Furthermore, the pressing device also includes a detection component, which includes a support plate, a spring, and a fourth sensor; the pressing head includes a movable tube and a fixed tube, the movable tube is slidably disposed inside the fixed tube, and one end of the movable tube extends out of the fixed tube and is fixedly connected to the support plate, the spring is disposed inside the fixed tube, one end of the spring is fixedly connected to the movable tube, and the free end is fixedly connected to the fixed tube, the fixed tube is fixedly disposed on the support platform, and the fourth sensor cooperates with the support plate to detect the distance the support plate moves after the movable tube is pressed to the installation position.

[0021] The principle and effect of this solution are as follows: If the sintered cotton is not installed in place (i.e., its end face is not in complete contact with the bottom surface of the joint mounting position), a gap will exist between the sintered cotton and the mounting position. This will not only fail to effectively intercept impurities in the gas, but may also cause displacement and detachment under the impact of gas flow. Furthermore, the sintered cotton should not be over-pressed during pressing, i.e., excessive compression of the pressing surface. Therefore, the movable tube in this solution can slide and extend within the fixed tube, and is reset by a spring. During pressing, the movable tube first contacts and adsorbs the sintered cotton. After the sintered cotton is pressed to the bottom surface of the joint mounting position, the subsequent pressing force will drive the movable tube to move in the opposite direction, causing the support plate to move towards the fourth sensor until the sensor detects the preset moving distance. It can detect whether the moving distance has not reached the preset value (sintered cotton not in place) or exceeded the preset value (over-pressing).

[0022] Furthermore, the detection component also includes a guide rail, one end of which is fixed on the press frame, and the free end passes through the support plate.

[0023] The principle and effect of this solution are as follows: the guide rail is used to provide positioning and guidance for the movement of the support plate, and to prevent the support plate from deviating.

[0024] Furthermore, it also includes a screening device, which includes a screening cylinder, a discharge hopper, and a distribution plate. The discharge hopper is fixedly mounted on the frame, and one end of the discharge hopper is located below the joint pressing station. The discharge hopper has a through groove, and the distribution plate is rotatably mounted in the through groove. The distribution plate is hinged to the piston rod of the screening cylinder. The screening cylinder is used to drive the distribution plate to rotate, thereby blocking or opening the through groove. The screening cylinder is electrically connected to a fourth sensor. The fourth sensor is used to control the piston rod of the screening cylinder to retract and open the through groove when the distance the support plate moves deviates from the preset distance.

[0025] The principle and effect of this solution are as follows: Under normal conditions, when the fourth sensor detects that the moving distance of the support plate is consistent with the preset value (sintered cotton is properly pressed), the piston rod of the screening cylinder remains extended, the material distribution plate rotates to the position of blocking the through slot, and the qualified connectors are transported along the discharge hopper track to the qualified product collection area for subsequent packaging processing; when the fourth sensor detects that the moving distance of the support plate deviates from the preset distance (sintered cotton is not in place or over-pressed, and is judged as unqualified product), it will immediately feed back an electrical signal to control the piston rod of the screening cylinder to retract, drive the material distribution plate to rotate to the position of opening the through slot, and the unqualified connectors will fall directly into the collection area through the through slot, thereby automatically screening and discharging qualified and unqualified connectors to meet the needs of large-scale production.

[0031] The following is in conjunction with the appendix Figure 2 The automatic pressing and sintering cotton equipment according to an embodiment of the present invention is described in detail. The frame 1 serves as the supporting foundation. The frame 1 is welded from stainless steel profiles, and adjustable leveling feet are provided at the four corners of the bottom to adjust the equipment's level according to on-site conditions. Along the material flow direction, the frame 1 is sequentially assembled with a joint feeding device 2, a sintering cotton feeding device 3, a transfer device 4, and a pressing device 5. A screening device 7 is correspondingly arranged below the pressing device 5.

[0032] Please see Figure 1 In this embodiment, the connectors 6 to be stamped and installed include three types: a single C, two Bs, and three As. All three types of connectors 6 are cylindrical structures with cylindrical grooves distributed axially. These grooves are the mounting positions 61 for assembling sintered cotton. The sintered cotton (not shown in the figure) fits perfectly with the shape of the mounting position 61. After pressing, it can tightly adhere to the inner wall of the mounting position 61, thereby intercepting impurities in the gas flowing through the connector 6.

[0033] Please see Figure 3 The joint feeding device 2 consists of a joint hopper 21, a vibrating hopper 22, and a first sensor 23. The joint hopper 21 is an annular box structure, fixed to one side of the frame 1. It can hold hundreds of joints 6 to be processed at one time, ensuring continuous feeding. The joint hopper 21 is a gravity-fed self-flowing hopper. A vibrator (not shown) is installed at the bottom of the joint hopper 21. The vibration generated by the vibrator drives the joints 6 in the hopper to move along the hopper wall towards the discharge port. The feed end of the vibrating hopper 22 is connected to the discharge port of the joint hopper 21. The track width of the vibrating hopper 22 is adapted to the outer diameter of the joints 6, so that the joints 6 are arranged along the track. The free end of the vibrating hopper 22 extends horizontally to the side of the joint pressing station 411. The outer wall of its discharge end is fixed to the first sensor 23 by a bracket. The first sensor 23 is a diffuse reflection photoelectric sensor, which can detect whether there is a joint 6 in place at the end of the track. The detection signal is transmitted to the control system to provide a trigger signal for subsequent transfer actions.

[0034] Please continue reading. Figure 3The sintered cotton feeding device 3 includes a sintered cotton hopper 31, a vibrating feeder 32, a second sensor 33, a baffle 34, and a stop block 35. The sintered cotton hopper 31 has the same structure as the joint hopper 21 and is fixed on the frame 1. Its discharge port is connected to the feed end of the vibrating feeder 32. The top of the vibrating feeder 32 has three parallel feeding grooves 321 along its length. The width of the feeding grooves 321 matches the diameter of the sintered cotton, allowing for the simultaneous feeding of multiple sets of sintered cotton and adapting to the pressing requirements of three different types of joints 6. A rectangular baffle 34 is fixed to the discharge end of the vibrating feeder 32 by bolts. The baffle 34 has threaded holes corresponding to each feeding groove 321. The stop block 35 has a cylindrical structure and threads machined on its outer surface. By rotating the stop block 35, its depth into the feeding groove 321 can be adjusted, thereby blocking or opening different feeding grooves 321. For example, when processing a single set of connectors 6, excess feed troughs 321 can be blocked to avoid ineffective feeding. The second sensor 33 is a fiber optic sensor, fixed above the discharge end of the vibrating feed hopper 32 by a bracket. Its detection head faces the end of the feed trough 321 and can detect the positioning status of the sintered cotton in each feed trough 321. The detection signal is electrically connected to the sintered cotton transfer cylinder 422, and the transfer action is only started after the sintered cotton has stably settled in position. Please continue reading. Figure 3 The transfer device 4 includes a joint transfer assembly 41 and a sintered cotton transfer assembly 42, which work together to align the joint 6 with the sintered cotton. The joint transfer assembly 41 consists of a joint pressing station 411, a joint transfer cylinder 412, a support platform 413, and a third sensor 414. The support platform 413 is made of high-strength rectangular steel plate, and its bottom slides with a linear guide rail on the frame 1 via a slider. The top of the support platform 413 is milled to form the joint pressing station 411, which is a circular groove that matches the shape of the joint 6. The groove depth is slightly less than the height of the joint 6, which can both initially position the received joint 6 and facilitate subsequent material discharge. The joint transfer cylinder 412 is horizontally fixed on the frame 1 by a bracket, and its piston rod end is fixedly connected to the support platform 413 via a joint. The third sensor 414 is an inductive proximity switch, which is embedded in the side of the connector pressing station 411 and electrically connected to the connector transfer cylinder 412. When the connector 6 falls into the connector pressing station 411, the third sensor 414 detects a metal signal and immediately feeds it back to the control system, triggering the piston rod of the connector transfer cylinder 412 to extend, driving the support platform 413 to move towards the pressing device 5 until the connector pressing station 411 reaches below the pressing device 5, completing the transfer and positioning of the connector 6.

[0035] Please continue reading 3 and... Figure 4The sintered cotton transfer assembly 42 includes a sintered cotton pressing station 421, a sintered cotton transfer cylinder 422, a support plate 423, a limiting plate 424, and a limiting cylinder 425. The support plate 423 is located above the support platform 413 and is fixedly connected to the piston rod of the sintered cotton transfer cylinder 422; the sintered cotton transfer cylinder 422 is fixed to the frame 1 by a bracket. The sintered cotton pressing station 421 is a circular through hole penetrating the support plate 423. The diameter of the through hole is slightly larger than the diameter of the sintered cotton but smaller than the diameter of the joint mounting position 61, which allows the sintered cotton to pass smoothly and guides it during pressing. The limiting plate 424 is a long strip of steel plate, which is fitted to the bottom of the supporting plate 423. One end of it is hinged to the piston rod of the limiting cylinder 425 by a pin. The cylinder body of the limiting cylinder 425 is fixed on the supporting plate 423. Under normal conditions, the piston rod of the limiting cylinder 425 is in the retracted state, which drives the limiting plate 424 to completely cover the bottom of the sintered cotton pressing station 421, providing support for the sintered cotton. The second sensor 33 is electrically connected to the sintered cotton transfer cylinder 422. When it is detected that the sintered cotton has been stably placed in the sintered cotton pressing station 421, the piston rod of the sintered cotton transfer cylinder 422 extends, which drives the supporting plate 423, the limiting plate 424 and the limiting cylinder 425 to move synchronously in the direction of the pressing device 5, so that the sintered cotton pressing station 421 is located directly above the joint pressing station 411, realizing the coaxial alignment of the sintered cotton and the joint installation position 61, which facilitates the subsequent pressing operation.

[0036] Please continue reading. Figure 4 and Figure 5 The pressing device 5 consists of a pressing frame 51, a pressing cylinder 52, a pressing head 53, a support platform 54, a vacuum pump 55, and a detection component 56. The pressing frame 51 is welded from square steel and fixed to the frame 1. The pressing cylinder 52 is a servo cylinder, which can control the extension speed and stroke of the piston rod and can realize segmented action. The end of the piston rod of the pressing cylinder 52 is fixedly connected to the support platform 54 by bolts. The two sides of the support platform 54 are slidably engaged with the guide sleeves on the pressing frame 51 through guide rods (not shown). The pressing head 53 has three sets, consisting of a movable tube 531 and a fixed tube 532. The fixed tube 532 is fixed to the support platform 54 by threads, and the movable tube 531 slides through the fixed tube 532. The gap between the two is very small, allowing the movable tube 531 to slide within the fixed tube 532. The lower end of the movable tube 531 is machined to fit the joint mounting position 61, which facilitates the smooth entry of the sintered cotton into the mounting position 61. Both the movable tube 531 and the fixed tube 532 are hollow structures. The upper end of the fixed tube 532 is connected to the vacuum pump 55 through a high-temperature resistant hose. The vacuum pump 55 is fixed to the side of the pressing frame 51. After starting, it can form a negative pressure in the movable tube 531, which can firmly adsorb the sintered cotton and solve the problem of pressing posture deviation caused by the soft texture and insufficient rigidity of the sintered cotton.

[0037] Please continue reading. Figure 4 and Figure 5 The detection component 56 includes a support plate 561, a spring (not shown), a fourth sensor 562, and a guide rail 563, used to detect whether the sintering cotton is installed in place. The support plate 561 is fixed to the upper end of the movable tube 531. The spring is sleeved on the outside of the movable tube 531 and located between the fixed tube 532 and the support plate 561. The elastic coefficient of the spring can be adaptively adjusted by those skilled in the art according to the operational requirements, so that it can provide a restoring force for the movable tube 531 and also play a buffering role during pressing to avoid rigid impact. The fourth sensor 562 is a laser displacement sensor, fixed to the side of the pressing frame 51 and corresponding to the support plate 561, which can detect the moving distance of the support plate 561 in real time. The guide rail 563 consists of three parallel and vertically arranged optical axes, one end of which is fixed to the pressing frame 51, and the other end slides through the support plate 561, providing guidance for the movement of the support plate 561 and ensuring the accuracy of the detection results of the fourth sensor 562. When the sintered cotton is pressed to the bottom surface of the joint installation position 61, the subsequent pressing force will drive the movable tube 531 to retract relative to the fixed tube 532, causing the support plate 561 to move towards the fourth sensor 562. The fourth sensor 562 will compare the detected moving distance of the support plate 561 with the preset value to determine whether the sintered cotton is installed in place or over-pressed.

[0038] Please continue reading. Figure 6 The screening device 7 is used to automatically separate qualified and unqualified connectors 6, and includes a screening cylinder 71, a discharge hopper 72, and a distribution plate 73. The upper end of the discharge hopper 72 is located directly below the connector pressing station 411, which facilitates the receiving of the connectors 6 after pressing. The main body of the discharge hopper 72 is inclined, and the bottom is provided with a qualified product discharge port. The discharge hopper 72 has a through groove, and a corresponding unqualified product collection box (not shown) is set below the through groove. The distribution plate 73 is rotatably installed in the through groove via a stainless steel rotating shaft. The size of the distribution plate 73 is adapted to the through groove. One end of the distribution plate 73 is hinged to the piston rod of the screening cylinder 71 via a connecting rod. The screening cylinder 71 is fixed to the side of the discharge hopper 72 by a bracket. The screening cylinder 71 is electrically connected to the fourth sensor 562. When the fourth sensor 562 detects that the moving distance of the support plate 561 is consistent with the preset value, it determines that the sintered cotton is installed correctly. The piston rod of the screening cylinder 71 remains extended, driving the material distribution plate 73 to block the through slot. The qualified connector 6 slides down the inclined track of the discharge hopper 72 to the qualified product collection box. When the fourth sensor 562 detects that the moving distance does not reach the preset value (sintered cotton not in place) or exceeds the preset value (over-pressing), it determines that it is a defective product. It immediately sends a feedback signal to control the piston rod of the screening cylinder 71 to retract, driving the material distribution plate 73 to rotate and open the through slot. The defective connector 6 falls into the special collection box through the through slot, realizing automatic screening and preventing defective products from flowing into the downstream process.

[0039] The automatic pressing and sintering cotton equipment of the present invention operates as follows: Before operation, the joints 6 to be processed are placed into the joint hopper 21, and the sintering cotton is placed into the sintering cotton hopper 31. According to the model of the joints 6 (single or multiple groups), the baffle 34 is adjusted to activate the corresponding number of feeding troughs 321. After the equipment is started, the control system links each device to act in sequence. The vibrating hopper 22 of the joint feeding device 2 vibrates, driving the joints 6 to be conveyed in sequence along the track. After the first sensor 23 detects that the joints 6 are in place, the joints 6 fall smoothly into the joint pressing and sintering device. At station 411, the third sensor 414 detects the placement signal of connector 6, triggering the connector transfer cylinder 412 to move the support platform 413 towards the pressing device 5 until the connector pressing station 411 reaches below the pressing device 5. Simultaneously, the vibrating feeder 32 of the sintered cotton feeding device 3 vibrates, and the sintered cotton is conveyed in sequence along the feeding trough 321. After the second sensor 33 detects that the sintered cotton has arrived, it triggers the sintered cotton transfer cylinder 422 to move the support plate 423, so that the sintered cotton pressing station 421 is precisely positioned at the connector. Directly above the pressing station 411, coaxial alignment is completed. Then, the piston rod of the pressing cylinder 52 extends a short distance, causing the lower end of the movable tube 531 of the pressing head 53 to contact the sintered cotton. The vacuum pump 55 starts, generating negative pressure to adsorb the sintered cotton. The piston rod of the limiting cylinder 425 extends, moving the limiting plate 424 away from the sintered cotton pressing station 421, removing the bottom obstruction. The pressing cylinder 52 continues to extend, driving the pressing head 53 to press the sintered cotton into the joint mounting position 61. When the end face of the sintered cotton contacts the bottom surface of the mounting position 61, the movable tube 531 is relatively fixed. When tube 532 retracts, it moves support plate 561 toward fourth sensor 562. Fourth sensor 562 detects the moving distance in real time and feeds it back to control system. After pressing is completed, vacuum pump 55 stops working, piston rod of pressing cylinder 52 retracts, moving tube 531 resets under spring action, joint transfer cylinder 412 drives bearing platform 413 to reset, and the pressed joint 6 falls into discharge hopper 72. Screening device 7 automatically screens qualified and unqualified products according to the detection result of fourth sensor 562, realizing continuous automated operation.
