Description

Technical Field

[0001] This invention relates to the field of connector assembly technology, specifically a housing connector assembly machine. Background Technology

[0002] Existing joint assembly technologies have several drawbacks. First, their feeding devices are generally only suitable for one type of joint. For assemblies with multiple joints, each joint requires a separate feeding device, resulting in the need for multiple feeding devices corresponding to different joint structures. Existing feeding devices that can only accommodate one type of joint not only occupy space but also significantly increase costs. Furthermore, when interfacing with other processes, different feeding devices need to be switched, increasing switching steps and impacting operational efficiency. Second, the assembly process is prone to problems such as material slippage during transitions. Summary of the Invention

[0003] This invention provides a shell connector assembly machine that is highly versatile, low-cost, space-saving, efficient, and stable in assembly.

[0004] To achieve the above objectives, the following technical solutions are employed.

[0005] A shell connector assembly machine includes a first double-turntable structure and a control system. The periphery of the first double-turntable structure is sequentially equipped with a connector feeding device, a connector orientation device, a first inspection station, a primary oiling station, a sealing ring feeding and unloading device, a second inspection station, a safety ring feeding device, a third inspection station, a secondary oiling station, a snap ring feeding device, a finished product inspection station, an airtightness inspection device, and an automatic packaging system. The connector feeding device comprises two parallel sets of feeding components, each serving as a universal channel for multiple connectors. A gap space exists between the two sets of feeding components, and each set of feeding components has a cutting component at its outer end that cuts away towards the gap space. After feeding, the connectors are cut away by the cutting component into the gap space. The connector orientation device then clamps the connectors within the gap space and transfers them to the first double-turntable structure. After orientation correction, they sequentially enter each station for inspection, oiling, and assembly. The assembled, high-quality products flow into the automatic packaging system for packaging.

[0006] Furthermore, the feeding assembly includes a feeding channel, which is a segmented channel, including a first channel segment and a second channel segment. The first channel segment and the second channel segment are connected end to end. The feeding channels in the two sets of feeding assemblies are the first feeding channel and the second feeding channel, respectively. The first feeding channel is suitable for feeding straight or regularly shaped joints, and the second feeding channel is suitable for feeding irregularly shaped joints with one or more bends or one or more protruding parts extending out of the joint cylinder.

[0007] Furthermore, the first feeding channel is a U-shaped channel structure, with guide plates provided at the open ends of the two side walls of the U-shaped channel, and guide strips protruding from the side walls on the inner sides of the two side walls of the U-shaped channel respectively; the second feeding channel is a frame structure with an opening at the top, including a base plate and two guide structures located above the base plate and distributed opposite to each other, with the two sides of the base plate connected to the outer side of the guide structures by a plurality of spaced connectors, the connectors being outwardly protruding connectors, and the connectors being distributed at a certain distance from each other.

[0008] Furthermore, a top-pressing assembly is provided above both the first and second feeding channels. The top-pressing assembly includes two or more inverted U-shaped lifting rings. The two sides of the inverted U-shaped lifting rings are fixed to the outside of the side walls of the first or second feeding channel. Each inverted U-shaped lifting ring has a top-pressing block with an elongated oval adjustment hole on either side along the length of the channel. The bottom of the top-pressing block is provided with a top-pressing crossbar, and both ends of the top-pressing crossbar are curved upwards.

[0009] Furthermore, the connector orientation device includes a moving module, on which an orientation clamping mechanism is provided. Below the orientation clamping mechanism is a rotating mechanism, on which a product fixture is provided. The orientation clamping mechanism includes a driving component, and at the bottom of the driving component is a station connecting plate. Both ends of the station connecting plate are provided with a direction identification component and a clamping component. The clamping component is used to clamp the housing connector and move it to the station where the direction identification component is located. The direction identification component is used to identify the direction of the housing connector, so that the direction of the loaded housing connectors is consistent.

[0010] Furthermore, the orientation recognition component includes an orientation recognition seat, a probe, and an orientation recognition block. The orientation recognition seat is fixed below the workstation connecting plate by a fine-tuning block. A probe penetrating the orientation recognition seat is provided on one side of the orientation recognition seat. The top end of the probe extends out after penetrating the workstation connecting plate, and the bottom end of the probe is provided with an orientation recognition block.

[0011] Furthermore, the direction recognition seat is provided with a first sliding sleeve, and the workstation connecting plate is provided with a second sliding sleeve. The probe passes through the direction recognition seat and the workstation connecting plate through the first sliding sleeve and the second sliding sleeve respectively, and can move up and down along the first sliding sleeve and the second sliding sleeve. The direction recognition block is a circular recognition block, and the bottom surface of the direction recognition block abuts against the upper surface of the lug protruding outward from the outer circumference of the housing connector.

[0012] Furthermore, the sealing ring feeding and unloading device includes a feeding mechanism, which includes a feeding frame. The feeding frame is equipped with a feeding vibrating plate, and the discharge end of the feeding vibrating plate is equipped with a conveying mechanism. The unloading mechanism is characterized in that: the discharge end of the conveying mechanism is equipped with a positioning mechanism, which includes a positioning station. One side of the positioning station is equipped with a pushing mechanism, and the other side is equipped with a picking station. A picking mechanism is located outside the picking station. The picking mechanism includes a picking claw, which includes a moving rod. The picking end of the moving rod is equipped with multiple elastic claw pieces, and the ends of the elastic claw pieces are V-shaped bends with the pointed ends protruding outwards. After the sealing ring is fed from the feeding mechanism, it is conveyed to the discharge end by the conveying mechanism. Then, the pushing mechanism pushes the sealing ring to the picking station. The picking mechanism then drives the picking claw to move down to the picking station, so that the sealing ring at the picking station enters above the arc portion of the picking claw, completing the unloading process.

[0013] Furthermore, the airtightness testing device includes a second double-rotor structure, a test frame, and an interface sealing mechanism. The second double-rotor structure is located outside the first double-rotor structure and includes a rotatable second large turntable and a fixed second small turntable. The second large turntable is located below the second small turntable, and multiple joint placement stations are evenly distributed on the portion of the second large turntable extending beyond the second small turntable. The test frame is equipped with a clamping mechanism for clamping the joints, and the interface sealing mechanism includes one or more interface sealing components. The sealing end of the interface sealing component is correspondingly set to the interface of the joint to be sealed.

[0014] Furthermore, the automatic packaging system includes a frame and a discharge channel. The discharge channel is located above the frame. A first package and a second package are provided on the frame. The first package is rotatably mounted on the frame. The second package is located on the side of the first package located in the discharge channel. The end and middle of the discharge channel are respectively provided with a first discharge port corresponding to the first package and an openable and closable second discharge port corresponding to the second package.

[0015] Compared with the prior art, the shell connector assembly machine of the present invention has the following advantages:

[0016] The shell connector assembly machine of this invention automates the entire process from connector feeding and orientation correction to finished product inspection and packaging. It has a high degree of automation and good connector assembly stability. The two sets of feeding devices are universal feeding structures that are compatible with various connector specifications, which is highly versatile. Only one connector feeding device is needed to feed various different connector materials, which greatly reduces the number of feeding devices. This not only saves space and reduces costs, but also avoids the need to switch devices between different connector materials, thus improving work efficiency. Attached Figure Description

[0044] The housing connector assembly machine of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0045] Reference Figure 1 and Figure 2A shell connector 350 assembly machine includes a first double turntable structure 100 and a control system. The first double turntable structure 100 has, in sequence, a connector feeding device 200, a connector orientation device 300, a sealing ring 4453 feeding and unloading device 400, a safety ring feeding device 500, a snap ring feeding device 600, an airtightness testing device 700, and an automatic packaging system 800. A first testing station 1 and a primary oiling station 2 are sequentially arranged between the connector orientation device 300 and the sealing ring 4453 feeding and unloading device 400. A second testing station 3 is arranged between the sealing ring 4453 feeding and unloading device 400 and the safety ring feeding device 500. A series of components are arranged between the safety ring feeding device 500 and the snap ring feeding device 600. The third inspection station 4 and the secondary oiling station 5 are located. A finished product inspection station 6 is provided between the snap ring feeding device 600 and the airtightness inspection device 700. The connector feeding device 200 includes two sets of feeding components distributed in parallel. The feeding components are all multi-connector universal channels. There is a gap space 270 between the two sets of feeding components. The outer end of each set of feeding components is provided with a cutting component that cuts away in the direction of the gap space 270. After the feeding components feed the material, they are cut away by the cutting component to the gap space 270. Then, the connector orientation device 300 clamps the connector in the gap space 270 and transfers it to the first double turntable structure 100. After orientation correction, the connectors enter each station in sequence for inspection, oiling and feeding assembly. The assembled good products flow into the automatic packaging system 800 for packaging.In this embodiment, the connector feeding device 200 is used to feed the housing connector 350. Specifically, according to the specifications of the housing connector 350, a set of feeding components is selected from the connector feeding device 200 to feed the housing connector 350. After the housing connector 350 is fed to the discharge end, the cutting component pushes the housing connector 350 to the position between the two sets of feeding components, corresponding to the connector orientation device 300. The connector orientation device 300 then clamps the housing connector 350 cut off by the cutting component and moves it to the first double turntable. The orientation correction station on structure 100 performs orientation correction. After orientation correction, the housing joint 350 rotates from the first double turntable structure 100 to the first inspection station 1. The first inspection station 1 checks whether there are foreign objects inside the housing joint 350. After one inspection, it enters the first oiling station 2 to apply oil to the inner surface of the housing joint 350. After the first oiling, the housing joint 350 continues to rotate forward to the sealing ring 4453 feeding and unloading device 400. The sealing ring 4453 feeding and unloading device 400 then performs the feeding and unloading operation. A sealing ring 4453 is fed into the housing joint 350. After the sealing ring 4453 is installed in the housing joint 350, the housing joint 350 continues to rotate forward to the second inspection station 3. The second inspection station 3 checks whether the sealing ring 4453 is installed in the housing joint 350. After the inspection, it enters the second oiling station 5, where oil is applied to the inner surface of the housing joint 350 and the sealing ring 4453. After the second oiling, the housing joint 350 continues to rotate from the first turntable structure to the snap ring feeding device 6. At position 00, the spring feeding device feeds and installs the retaining ring into the housing joint 350. After the retaining ring is installed, the device continues to rotate forward to the finished product inspection station 6. The finished product inspection station 6 performs finished product inspection on the housing joint 350 assembled with the sealing ring 4453 and the retaining ring to check whether the sealing ring 4453 or the retaining ring is missing. After the finished product inspection, the good products enter the airtightness testing device 700 for finished product airtightness testing, and then enter the automatic packaging system 800 for finished product packaging and warehousing. Defective products flow into the defective product channel.

[0046] Reference Figure 1 , Figures 3 to 10The two feeding components are a first feeding component 210 and a second feeding component 220, both of which include a feeding channel. The feeding channel is a segmented channel, comprising a first channel segment and a second channel segment, which are connected end-to-end. The feeding channels in the two feeding components are a first feeding channel 211 and a second feeding channel 221. The first feeding channel 211 is suitable for feeding straight or regularly shaped joints, while the second feeding channel 221 is suitable for feeding irregularly shaped joints with one or more bends or one or more protruding portions extending from the joint cylinder. In this embodiment, the segmented channel structure divides the feeding channel into a first channel segment and a second channel segment, with the first and second channel segments connected end-to-end. This not only effectively ensures stable transmission through the segmented channel but also allows any one of the channel segments to be used as an extension channel, facilitating maintenance by operators. In the event of a feeding channel malfunction, timely repairs are ensured, thereby ensuring smooth feeding. In this embodiment, the first feeding channel 211 is compatible with feeding a variety of different joint materials, and the second feeding channel 221 is compatible with feeding a variety of different joint materials. The two sets of feeding components of the joint feeding device 200 can be compatible with feeding a variety of different joint materials, which is highly versatile. Only one joint feeding device 200 is needed to complete the feeding of a variety of different joint materials, which greatly reduces the number of feeding devices. It not only occupies less space and greatly reduces costs, but also avoids the switching of devices between feeding different joint materials, thus improving the efficiency of operation. Specifically, the connector feeding device 200 further includes a first feeding component 230 and a second feeding component 240 respectively connected to the first feeding component 210 and the second feeding component 220. The first feeding component 230 includes a first vibrating plate 231 and a first feeding rack 411232. The first vibrating plate 231 is disposed on the first feeding rack 411232, and the discharge channel 840 of the first vibrating plate 231 is connected to the first feeding channel 211 in the first feeding component 210. The second feeding component 240 includes a second vibrating plate 241 and a second feeding rack 411242. The second vibrating plate 241 is disposed on the second feeding rack 411242, and the discharge channel 840 of the second vibrating plate 241 is connected to the second feeding channel 221 in the second feeding component 220.

[0047] Reference Figure 1 , Figures 3 to 10The first feeding channel 211 is a U-shaped channel structure. Guide plates 2111 are provided at the open ends of both side walls of the U-shaped channel, and guide strips 2112 protruding from the side walls are provided on the inner sides of both side walls. The first feeding channel 211 adopts a U-shaped channel structure, which is suitable for various straight cylindrical circular connectors, as well as circular connectors with an inclined bent pipe-like interface on one side. Specifically, it can accommodate the feeding of various connector materials. The guide plates 2111 at the open ends of both side walls of the U-shaped channel are used to engage the notch at the top of the connector material within the U-shaped channel, providing guidance for the connector material at its upper part. The guide strips 2112 protruding from the side walls on the inner sides of the U-shaped channel are used to engage the connector on the cylindrical body of the connector, providing guidance for the connector in the middle of the connector material, ensuring the stability of the connector feeding. The second feeding channel 221 is a frame structure with an opening at the top, including a base plate 2211 and two guide structures 2212 located above the base plate 2211 and distributed opposite each other. The two sides of the base plate 2211 are connected to the outer sides of the guide structures 2212 by a plurality of spaced-apart connectors 2213. The connectors 2213 are protruding outward connectors 2213, and the connectors 2213 are distributed at a certain distance from each other. Specifically, the upper and lower ends of the connector 2213 are connected to the outer side of the guide structure 2212 and the outer side of the base plate 2211, respectively. The middle part of the connector 2213 protrudes outward, making the entire connector 2213 a flattened "U" shape. This outward protrusion of the middle part of the connector 2213 increases the conveying space in the second feeding channel 221, which greatly saves the raw material cost of the second feeding channel 221 while ensuring the structural stability of the second feeding channel 221. The second feeding channel 221 of the frame structure is suitable for conveying various irregularly shaped joint materials. Specifically, it can accommodate the feeding of various irregularly shaped joint materials. The base plate 2211 in the frame structure is used to provide support for the joint material. The two guide structures 2212 distributed opposite to each other above the base plate 2211 cooperate with the joint to be conveyed to engage the joint and provide guidance for the joint. The connectors 2213 that connect the base plate 2211 and the guide structures 2212 at both ends provide support for the guide structures 2212 and can greatly save materials, thereby saving costs.

[0048] Reference Figure 1 , Figures 3 to 10Above the first feeding channel 211 and the second feeding channel 221, a top-pressing assembly 250 is provided. The top-pressing assembly 250 includes two or more inverted U-shaped lifting rings 251. The two sides of each inverted U-shaped lifting ring 251 are fixed to the outer side walls of the first feeding channel 211 or the second feeding channel 221. Each inverted U-shaped lifting ring 251 has a top-pressing block 252 with an elongated adjusting hole on either side along the channel length. The bottom of each top-pressing block 252 has a top-pressing crossbar 253, with both ends of the crossbar 253 curving upwards. The top-pressing assembly 250 is used to press down on the joint material within the U-shaped channel or frame-type structure channel, preventing the joint material from shaking and damaging itself during feeding. Specifically, the top-pressing assembly 250 includes two or more U-shaped lifting rings fixed to the side walls of the first feed channel 211 and the second feed channel 221. The U-shaped lifting rings have top-pressing blocks 252, and the bottom of the top-pressing blocks 252 is fixed with a top-pressing crossbar 253. These components are used to press down on the joint material, preventing it from shaking during feeding and causing damage. In this embodiment, both ends of the top-pressing crossbar 253 are upwardly curved, meaning both ends of the top-pressing crossbar 253 have upwardly curved portions. This curved portion facilitates installation and disassembly.

[0049] Reference Figure 1 , Figures 3 to 10 Below both the first and second channel sections, a direct vibration assembly 260 is provided to abut against the channel. The direct vibration assembly 260 includes a mounting frame 261 and a direct vibration device 262. The direct vibration device 262 is located on top of the mounting frame 261. The mounting frame 261 is an adjustable mounting frame, including an I-beam frame 2611 and a top plate 2612. The top plate 2612 is movably connected to the upper plate of the I-beam frame 2611 via an adjusting member 2613. During the material conveying process, the direct vibration device 262 in the direct vibration assembly 260 is activated, causing the first and second channel sections above it to vibrate, thus moving the material on them and ultimately conveying the material to its position. The adjustable mounting frame 261 mainly consists of the I-beam frame 2611 and the top plate 2612. The top plate 2612 is connected to the I-beam frame 2611 via the adjusting member 2613, facilitating the installation of the direct vibration device 262.

The first changing fixture 213 is fixed on the gripper of the first directional clamping member 3242126. After the joint material is conveyed into the first changing fixture 213, the first directional clamping member 3242126 is activated, driving the first changing fixture 213 to clamp the joint material. At this time, the first cutting drive member 2123 is activated, driving the first directional clamping member 3242126 to move the joint material on it together with the first slide block 2125 towards the second feeding channel 221 to a suitable position corresponding to the joint orientation device 300, so that the joint orientation device 300 can clamp and operate.

The movable module 310 is used to drive the directional clamping mechanism 320 to move, so that the directional clamping mechanism 320 clamps the shell joint 350 in the previous process feeding channel and moves it to the direction correction station, that is, the station where the direction identification component 323 is located.Specifically, the rotating mechanism 340 is located at the orientation correction station. The directional clamping mechanism 320 clamps the housing joint 350 and moves it into the product fixture 330 on the rotating mechanism 340. Then, the driving component 321 in the directional clamping mechanism 320 located above the rotating mechanism 340 drives the station connecting plate 322 and its orientation identification component 323 to move downwards and contact the housing joint 350 to identify the orientation of the housing joint 350. If the orientation is correct, it flows into the next station. In this embodiment, the orientation... The driving component 321 is a driving cylinder, and the directional clamping component 324 is a clamping cylinder. The driving cylinder is connected to the moving module 310 through the cylinder fixing plate 325 and the slider 326. It is driven by the moving module 310 to move back and forth along the module driving direction. First, the moving module 310 drives the driving cylinder in the directional clamping mechanism 320 to move above the housing joint 350 at the discharge end of the feeding channel. Then, the driving cylinder drives the station connecting plate 322 and the directional clamping component 324 installed below the station connecting plate 322, i.e., the clamping cylinder. The cylinder moves down to a suitable position, and the clamp cylinder activates to clamp the housing connector 350. After the clamp cylinder clamps the housing connector 350, the drive cylinder drives the clamp cylinder to move the housing connector 350 upward, disengaging it from the discharge end of the feeding channel. Then, the clamp cylinder clamping the housing connector 350, along with the station connecting plate 322 and the drive cylinder, is moved by the moving module 310 towards the direction correction station, above the product fixture 330 at the direction correction station. Then, the drive cylinder activates to drive the station connecting plate 322 and the clamp cylinder to move downward, causing the housing connector clamped by the clamp cylinder to move downward. When connector 350 enters the product fixture 330, the clamp cylinder releases and returns to its original position. At this time, the drive cylinder drives the station connecting plate 322 and the fine-tuning block 3234 connected to it to move the probe 3232 and the direction identification block 3233 downwards through the direction identification seat 3231 to contact the housing connector 350 and identify the direction of the housing connector 350. If the direction of the housing connector 350 is found to be incorrect after identification, the rotation mechanism 340 is activated, driving the product fixture 330 to rotate the housing connector 350 to the correct position before flowing into the next station. This technical solution automates the entire process from clamping and moving the housing connector 350 to the direction correction station, as well as identifying and correcting the direction of the housing connector 350 at the direction correction station. This process is highly automated and efficient, effectively ensuring the consistency of the housing connector 350's direction and greatly facilitating the assembly of subsequent components within the housing connector 350, thus simplifying the manufacturing process of subsequent steps.

[0053] Reference Figure 1 , Figure 2 ,as well as Figures 11 to 14The orientation recognition component 323 includes an orientation recognition seat 3231, a probe 3232, and an orientation recognition block 3233. The orientation recognition seat 3231 is fixed below the workstation connecting plate 322 by a fine-tuning block 3234. A probe 3232 is provided on one side of the orientation recognition seat 3231, penetrating the seat. The top end of the probe 3232 extends out after penetrating the workstation connecting plate 322, and the bottom end of the probe 3232 is provided with an orientation recognition block 3233. In this embodiment, the orientation recognition seat 3231, together with the workstation connecting plate 322 located above, ensures good stability of the probe 3232 as it passes through the workstation connecting plate 322 and the orientation recognition seat 3231, and moves up and down along the workstation connecting plate 322 and the orientation recognition seat 3231. This ensures the accuracy of the orientation recognition block 3233 at the bottom of the orientation probe 3232 in recognizing the orientation of the housing connector 350.

[0054] Reference Figure 1 , Figure 2 ,as well as Figures 11 to 14The direction recognition seat 3231 is provided with a first sliding sleeve 3235, and the workstation connecting plate 322 is provided with a second sliding sleeve 3236. The probe 3232 passes through the direction recognition seat 3231 and the workstation connecting plate 322 through the first sliding sleeve 3235 and the second sliding sleeve 3236 respectively, and can move up and down along the first sliding sleeve 3235 and the second sliding sleeve 3236. In this embodiment, the first sliding sleeve 3235 and the second sliding sleeve 3236 provide guidance and protection for the probe 3232, allowing the probe 3232 to move up and down along the first sliding sleeve 3235 and the second sliding sleeve 3236, avoiding direct contact between the probe 3232 and the workstation connecting plate 3232 and the direction recognition seat 3231, and improving the service life of the probe 3232. The direction recognition block 3233 is a circular recognition block, and the bottom surface of the direction recognition block 3233 abuts against the upper surface of the lug protruding outward from the outer circumference of the housing connector 350. In this embodiment, the directional drive component 321 activates the drive station connection plate 322 to drive the direction recognition seat 3231 and its probe 3232. The direction recognition block 3233 at the bottom of the probe 3232 moves downward together until the bottom surface of the direction recognition block 3233 abuts against the upper surface of the lug. The probe 3232 senses the height of the direction recognition block 3233 at this time and determines the direction of the housing connector 350. Specifically, the outer circumferential surface of the housing connector 350 is provided with a set of high lugs and a set of low lugs. The high lug set consists of two high lugs 351, and the low lug set consists of two low lugs 352. The four lugs are evenly spaced, that is, the high lug set and the low lug set are distributed opposite to each other along the center of the housing connector 350. Regardless of whether the probe 3232 senses that the direction recognition block 3233 abuts with any of the high lugs 351 in the high lug set, or the probe 3232 senses that the direction recognition block 3233 abuts with any of the low lugs 352 in the low lug set, it can compare with the preset orientation of the housing connector 350 and rotate the housing connector 350 to complete the orientation correction of the housing connector 350. The orientation correction is convenient, quick and efficient.

[0055] Reference Figure 1 , Figure 2 ,as well as Figures 11 to 14 Both ends of the workstation connecting plate 322 are provided with directional clamping components 324, which are located outside the direction identification component 323. In this embodiment, the directional clamping components 324 are used to clamp the housing joint 350 in the feeding channel and move the clamped housing joint 350 to the direction correction station. At the direction correction station, the direction identification component and the rotating mechanism 340 together identify and correct the direction of the housing joint 350.

[0056] Reference Figure 1 , Figure 2 ,as well as Figures 11 to 14The rotating mechanism 340 includes a rotating drive component 341, a belt 342, and a rotating spindle 343. The rotating drive component 341 is connected to the rotating spindle 343 via the belt 342. The rotating spindle 343 is connected to the product fixture 330, and the rotating spindle 343 drives the product fixture 330 to rotate. In this embodiment, when the orientation recognition component 323 detects that the orientation of the housing joint 350 is incorrect, the rotating drive component 341 in the rotating mechanism 340 is activated, driving the rotating spindle 343 via the belt 342 to rotate the product fixture 330 and its housing joint 350 to the correct position, thus correcting the orientation of the housing joint 350. Further, the rotating mechanism 340 also includes a protective frame 344. The rotating spindle 343 is installed inside the protective frame 344 and extends out of the top plate 2612 of the protective frame 344 before connecting to the product fixture 330. The rotating drive component 341 is located on one side outside the protective frame 344. In this embodiment, the protective frame 344 is provided so that the rotating spindle 343 is placed inside the protective frame 344, which protects the rotating spindle 343 and effectively reduces the potential risks caused by the rotating spindle 343 being exposed.

[0057] Reference Figure 1 , Figure 2 ,as well as Figures 11 to 14 In a non-limiting embodiment of the present invention, a sensing bracket 345 is provided on one side of the protective frame 344, and a sensor 346 is provided on the top of the sensing bracket 345 for sensing the housing connector 350 inside the product fixture 330. Specifically, the sensor 346 is an optical fiber sensor 346. The optical fiber sensor 346 has the advantages of sensitivity, accuracy, strong adaptability, and compactness. In this embodiment, the sensing bracket 345 and the sensor 346 thereon are used to sense whether there is a housing connector 350 inside the product fixture 330, ensuring that the direction recognition component 323 only moves down to identify the direction of the housing connector 350 when there is a housing connector 350 inside the product fixture 330.

[0058] Reference Figure 1 , Figure 2 ,as well as Figures 15 to 19The sealing ring 4453 feeding and unloading device 400 includes a feeding mechanism 410, which includes a feeding rack 411. The feeding rack 411 is equipped with a feeding vibrating disc 412. The discharge end of the feeding vibrating disc 412 is equipped with a conveying mechanism 420. The discharge end of the conveying mechanism 420 is equipped with a positioning mechanism 430. The positioning mechanism 430 includes a positioning station 431. One side of the positioning station 431 is equipped with a pushing mechanism 432, and the other side is equipped with a picking station 433. The outside of the picking station 433 is equipped with a picking mechanism 440, which includes a picking claw 445. The picking claw 445 includes a moving rod 4451. The picking end of the moving rod 4451 is provided with multiple elastic claw pieces 4452. The end of the elastic claw piece 4452 is a V-shaped bend 44521 with the tip protruding outward. After the sealing ring 4453 is fed from the feeding mechanism 410, it is conveyed to the discharge end by the conveying mechanism 420. Then, the pushing mechanism 432 pushes the sealing ring 4453 to the picking station 433. Then, the picking mechanism 440 drives the picking claw 445 to move down to the picking station 433, so that the sealing ring 4453 at the picking station 433 enters above the arc part 44522 of the picking claw 445, thus completing the picking. In this embodiment, the sealing ring 4453 picking device mainly consists of a feeding mechanism 410, a picking device, and a conveying mechanism 420 disposed between the feeding mechanism 410 and the picking device. Its overall structure has few components and is simple. During operation, the feeding mechanism 410 feeds the sealing ring 4453 to the conveying mechanism 420, which then conveys it to the discharge end. At this time, the pushing mechanism 432 on the discharge end side pushes the sealing ring 4453 to the picking station 433. Then, the picking mechanism 440 activates its picking claw 445 to move the sealing ring 4453 towards the discharge end. The material is moved from the picking end of the picking claw 445 to the V-shaped tip of the V-shaped bend 44521 on the picking claw 445, so that the V-shaped bend 44521 stops the sealing ring 4453, thus completing the picking of the sealing ring 4453. The whole operation process is simple and convenient. The picking mechanism 440 can complete the picking by always moving in one direction. It effectively avoids the situation that the sealing ring 4453 is easy to fall off or be damaged when using pneumatic or electric grippers in the prior art, thus avoiding rework and greatly improving the operation efficiency.

[0059] Reference Figure 1 , Figure 2 ,as well as Figures 15 to 19The V-shaped bend 44521 has an outward protrusion of an arc 44522, which facilitates the external drive component 321 to smoothly pass over the arc 44522 to complete the material picking up by the picking claw 445 during the process of the drive moving rod 4451 driving the elastic claw 4452 and the sealing ring 4453 to continue moving, thus ensuring material picking efficiency. Multiple elastic claw plates 4452 are spaced apart on the outer circumferential surface of the moving rod 4451. The outer contour dimension formed by the material-grabbing end of the V-shaped bend 44521 of the multiple elastic claw plates 4452 is smaller than the inner diameter of the sealing ring 4453, ensuring that the end of the material-grabbing claw 445 smoothly enters the sealing ring 4453 when it moves towards the sealing ring 4453. The outer contour dimension formed by the arc portion 44522 of the V-shaped bend 44521 of the multiple elastic claw plates 4452 is larger than the inner diameter of the sealing ring 4453, so that the material-grabbing claw 445 extends into the sealing ring 4453. As the sealing ring 4453 continues to move forward, it undergoes elastic deformation under the support of the arc portion 44522 of the V-shaped bend 44521. After successfully passing through the arc portion 44522, the sealing ring 4453 returns to its original shape and is stopped by the arc portion 44522 of the V-shaped bend 44521 on the elastic claw 4452. This prevents the sealing ring 4453 from falling off the picking claw 445, ensuring convenient material picking by the picking claw 445 and avoiding rework due to the sealing ring 4453 falling off, thus ensuring work efficiency.

[0060] Reference Figure 1 , Figure 2 ,as well as Figures 15 to 19 The movable rod 4451 has multiple spaced-apart receiving grooves 4454 on its outer circumferential surface, and the elastic claw 4452 is fixed within the receiving grooves 4454. In this embodiment, the receiving grooves 4454 on the movable rod 4451 allow the elastic claw 4452 to be placed within them, with its outer surface aligned with the outer circumferential surface of the movable rod 4451. This ensures the compact structure of the picking claw 445 and prevents interference with other components caused by the elastic claw 4452 protruding from the movable rod 4451, further ensuring operational efficiency. Specifically, in this embodiment, the upper part of the elastic claw 4452 has one or more fixing holes 44523. After the elastic claw 4452 is placed in the receiving groove 4454, it is fixed within the receiving groove 4454 using fastening screws at the fixing holes 44523.

[0061] Reference Figure 1 , Figure 2 ,as well as Figures 15 to 19The conveying mechanism 420 includes a conveying channel 421. One end of the conveying channel 421 is connected to the discharge end of the feeding mechanism 410, and the other end is connected to the positioning mechanism 430. A straight vibrator 422 is provided at the bottom of the conveying channel 421. The straight vibrator 422 is mounted on the fine-tuning frame 423. The straight vibrator 422 in this embodiment has the same structure and principle as the straight vibrator in the feeding device described above, and will not be described again here. In this embodiment, the setting of the straight vibrator 422 at the bottom of the conveying channel 421 allows the sealing ring 4453 to be effectively dispersed under the action of the straight vibrator 422 after entering the conveying channel 421. This ensures that the sealing rings 4453 that accumulate during feeding by the feeding mechanism 410 are conveyed forward one by one in sequence, avoiding rework caused by material accumulation, thereby ensuring work efficiency.

[0062] Reference Figure 1 , Figure 2 ,as well as Figures 15 to 19 The positioning mechanism 430 includes a positioning mounting frame 434, and the positioning station 431 is located in the middle of the positioning mounting frame 434. The pushing mechanism 432 and the picking station 433 are located on the outer sides of the positioning station 431, respectively. The two sides of the positioning station 431 are respectively provided with movable spaces for the pushing mechanism 432 and the sealing ring 4453 to pass through. In this embodiment, the positioning station 431 is set to connect with the conveying channel 421 and receive the sealing ring 4453 conveyed by the conveying channel 421. The pushing mechanism 432 and the picking station 433 are respectively set on both sides of the positioning station 431. The pushing mechanism 432 is used to push the sealing ring 4453 at the positioning station 431 to the picking station 433, so that the sealing ring 4453 is picked up by the picking mechanism 440 at the picking station 433. This structure is reasonably distributed, occupies little space, and effectively ensures work efficiency.

The fine-tuning components 435 are used to fine-tune the positions of the mounting frame 261 and the fine-tuning frame 423, ensuring their precise positioning and thus ensuring work quality and efficiency. Specifically, the fine-tuning components 435 on the mounting frame 261 are located on one side of the base plate 2211 of the mounting frame 261, used to fine-tune the relative position of the mounting frame 261 and the conveying mechanism 420, ensuring the precise position of the positioning station 431 on the mounting frame 261; the fine-tuning frame 423 is equipped with two sets of fine-tuning components 435, one set located on one side of the base plate 2211 of the fine-tuning frame 423 for overall front-to-back fine-tuning, and the other set located in the middle of the fine-tuning frame 423 for upper-to-low fine-tuning, ensuring the precise position of the vibrator 262 on the fine-tuning frame 423.

The moving mechanism 441 is mounted on the material handling frame 443, and the upper and lower cylinder 442 is mounted on the moving mechanism 441 and is driven to move by the moving mechanism 441. The driving end of the upper and lower cylinder 442 is provided with a lifting frame 444, and the lifting frame 444 is provided with a material handling claw 445. In this embodiment, the moving mechanism 441 in the material handling mechanism 440 is used to drive the upper and lower cylinder 442 and the material handling claw 445 to move together to above the material handling station 433. The upper and lower cylinder 442 is activated to drive the material handling claw 445 to move down to pick up the sealing ring 4453. After the material handling is completed, the upper and lower cylinder 442 returns to its original position, and the moving mechanism 441 drives the upper and lower cylinder 442 and the material handling claw 445 to move together to the next station. This material handling mechanism 440 operates automatically throughout the entire process and has high work efficiency. Specifically, the moving mechanism 441 includes a motor 4411 and a moving fixed plate 4413. The motor 4411 is located on the side of the picking rack 443 away from the picking station 433. The moving fixed plate 4413 is located on the side of the picking rack 443 located at the picking station 433. The driving end of the motor 4411 is connected to a rotating rod 4412. The moving fixed plate 4413 is provided with an arched semi-circular movable space 44131. The rotating rod 4412 is located in the semi-circular movable space 44131. The outer end of the rotating rod 4412 is connected to an upper and lower cylinder 442 through a connecting plate 446 and a cylinder fixing frame 447. A picking claw 445 is provided below the upper and lower cylinders 442. In practice, the motor 4411 starts and drives the rotating rod 4412 to move within the semi-circular movable space 44131. The rotating rod 4412, through the connecting plate 446 and the cylinder fixing frame 447, drives the upper and lower cylinders 442 and the picking claw 445 connected to it to move to a suitable position. When the picking claw 445 moves above the picking station 433, the upper and lower cylinders 442 start and drive the picking claw 445 to move down. The picking claw 445 extends into the sealing ring 4453 below and continues to move down. The sealing ring 4453 is then pushed open by the V-shaped bend 44521 on the picking claw 445 and passes over the V-shaped tip of the V-shaped bend 44521, so that the sealing ring 4453 is tightly fitted onto the picking claw 445, completing the picking of material by the picking claw 445.

The end and middle of the discharge channel 840 are respectively provided with a first discharge port 841 corresponding to the first packaging component 820 and an openable and closable second discharge port 842 corresponding to the second packaging component 830. The first package 820 and the second package 830 are configured to package products in different ways. Both a first discharge port 841 and a second discharge port 842 are provided on the same discharge channel 840, and the second discharge port 842 is an openable discharge port. Specifically, a first discharge port 841 corresponding to the first package 820 is provided at the end of the discharge channel 840, and a second discharge port 842 corresponding to the second package 830 is provided in the middle of the discharge channel 840. The arrangement of the first discharge port 841 and the second discharge port 842 allows operators to choose either the first package 820 or the second package 830 for packaging materials according to actual needs, thereby enabling the packaging of the second package 830. The discharge port 842 is opened and closed. Specifically, when the operator selects the first package 820 to pack materials, the second discharge port 842 is closed, allowing the material in the discharge channel 840 to flow directly to the first discharge port 841 located at the end of the channel and fall into the first package 820, where it is packed. When the operator selects the second package 830 to pack materials, the second discharge port 842 is opened. At this time, the material in the discharge channel 840 will fall from the second discharge port 842 into the second package 830, where it is packed. This method is not only convenient to operate but also highly efficient and has a wide range of applications.

[0071] Reference Figure 1 , Figure 2 ,as well as Figures 23 to 27 The discharge channel 840 is an inclined channel, and an observation hole 843 is provided on the top plate of the discharge channel 840. A detachable transparent plate 850 is provided on the observation hole 843. In this technical solution, the discharge channel 840 is set as an inclined channel to facilitate the downward movement of materials under their own weight. The combination of the observation hole 843 and the transparent plate 850 on the top plate of the discharge channel 840 allows operators to observe the material flow in the discharge channel 840 in real time. If any jamming is found, the transparent plate 850 can be removed to clear the jamming and ensure the normal flow of materials in the discharge channel 840.

[0072] Reference Figure 1 , Figure 2 ,as well as Figures 23 to 27 The bottom plate of the discharge channel 840 is provided with a second discharge port 842.

The arrangement of the second discharge port 842 and the corresponding opening / closing component 860 on the bottom plate 2211 of the discharge channel 840 allows the opening / closing component 860 to open the second discharge port 842 when the material needs to be collected and packaged using the second packaging component 830. At this time, the material in the discharge channel 840 will fall from the second discharge port 842 as it flows through it, falling into the second packaging component 830 below the second discharge port 842, where the second packaging component 830 collects and packages the material. Specifically, the opening / closing component 860 includes an opening / closing cylinder 861 and an opening / closing assembly. The opening / closing cylinder 861 is fixed to the bottom of the discharge channel 840, and the pushing end 865 of the opening / closing cylinder 861 is fixedly connected to the opening / closing assembly. The opening / closing cylinder 861 is connected to the system control mechanism. When it is necessary to open or close the second discharge port 842, the control mechanism controls the opening / closing cylinder 861 to drive the opening / closing assembly to close or open the second discharge port 842. It has a high degree of automation and high efficiency. The opening / closing assembly includes an opening / closing plate 862 that cooperates with the L-shaped guide plate 845. The opening / closing plate 862 has a push plate 864 at one end of the opening / closing cylinder 861. The push plate 864 is fixedly connected to the pushing end 865 of the opening / closing cylinder 861. The push plate 864 has a reinforcing plate 863 on the side away from the opening / closing cylinder 861. The reinforcing plate 863 is a triangular rib. The opening and closing assembly mainly consists of an opening and closing plate 862 and a push plate 864 located at one end of the opening and closing plate 862. The assembly has a simple structure and is easy to manufacture. The push plate 864 is fixedly connected to the pushing end 865 of the opening and closing cylinder 861, allowing the cylinder to control the opening and closing plate 862 to extend into or exit the second discharge port 842 via the push plate 864. A reinforcing plate 863 is provided on the side of the push plate 864 away from the cylinder 861 to enhance its stability.
