Description

Technical Field

[0001] This application relates to the field of connector assembly technology, and in particular discloses an automated connector assembly production line. Background Technology

[0002] In automated assembly lines, the recycling of carrier components is a key link in achieving continuous production. Traditional assembly lines typically use two methods to achieve carrier repositioning: The first is to use robotic arms for transport-type repositioning. A dedicated robotic arm picks up the carrier component and transfers it from the end of one track to the beginning of another. This method requires additional robotic arms, and considering that the robotic arm's running path cannot interfere with other parts on the assembly line, the overall length and width of the production line need to be increased. In addition, the robotic arms themselves are expensive, and the action cycle of picking up the carrier component from one track and placing it on another track is relatively long, affecting the overall operating efficiency of the assembly line. The second method is to achieve the cyclical transport of carrier components through common closed loop tracks. Although this method does not require robotic arms and does not have a long repositioning cycle, during the carrier turning process, in order to ensure that the carrier component can run smoothly without jamming, the loop track must be designed with a large turning radius. This leads to an increase in the width of the production line layout, which is very unfriendly in small factory spaces.

[0003] Both of these common methods of transposing vehicle components have obvious drawbacks: the robotic arm solution sacrifices length space, increases costs, and has low production line efficiency, while the circular track solution sacrifices width space and is not conducive to the layout of small factories. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this application is to provide an automated assembly production line for connectors that is compact in structure, low in cost, and allows for easy replacement of carrier components without affecting the operation of other parts on the production line.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an automatic assembly production line for joints, comprising: a working platform; a return line mechanism: the return line mechanism is installed on the working platform, and the return line mechanism is provided with several carrier components; a feeding mechanism: the feeding mechanism includes several feeding units; an assembly mechanism: the assembly mechanism includes a rotary assembly component and a linear assembly component, the rotary assembly component includes an indexing turntable and an assembly unit, the assembly unit is configured with a corresponding feeding unit, the assembly unit takes materials from the feeding unit and assembles them on the indexing turntable, after assembly, the workpiece flows from the indexing turntable to the carrier component, and the linear assembly component includes several unloading units and several... Each of the feeding units is equipped with a corresponding loading unit. The feeding unit takes materials from the loading unit and places them on the corresponding workpiece for assembly. After assembly, the corresponding positioning detection unit operates to ensure that the workpiece is assembled in place. The unloading mechanism separates the assembled workpieces into qualified and unqualified categories for unloading. The return line mechanism includes a linear track and a shifting component. There are two linear tracks arranged in parallel, and the two linear tracks run in opposite directions. There are two shifting components located at the two ends of the linear tracks. When the carrier component moves to the end of the linear track, the shifting component pushes or pulls the carrier component into the other linear track.

[0006] As a preferred embodiment, the linear track includes a toothed belt and a fixed slide rail. The shifting assembly includes a first bracket, a second bracket, and a support seat. The first bracket is fixedly mounted on the working platform. The second bracket is slidably mounted on the first bracket in a vertical direction. The support seat is slidably mounted on the second bracket in a front-back direction. A short rail is fixedly mounted on the support seat, and the short rail is adapted to the fixed slide rail. The carrier assembly includes a base. A slider and a slide block are fixedly mounted on the lower side of the base. The slide blocks are symmetrically arranged on the front and rear sides of the slider. A slide block adapted to the short rail is provided on the lower side of the slider. The slide block has a toothed protrusion on its lower side, which is adapted to the straight toothed belt. During the operation of the return line mechanism, only one side of the slide block engages with the corresponding straight toothed belt. When the carrier assembly moves to the end of the linear track, the slider slides from the fixed slide rail into the short rail. The carrier moves to separate the toothed protrusion on the engaged side from the straight toothed belt. The carrier continues to move until the toothed protrusion on the other side engages with another straight toothed belt. At the same time, the short rail connects with the fixed slide rail on that side, and the carrier assembly completes the repositioning.

[0007] As a preferred embodiment, the indexing turntable includes a turntable and an indexing drive device. The indexing drive device is located below the turntable and controls the turntable to rotate periodically and intermittently. Several tilting carriers are fixedly mounted on the upper side of the turntable. Each tilting carrier includes a bearing, a platform, a first gear, and a locking device. The platform is adjustablely rotatably mounted on the bearing. The first gear is mounted on one side of the platform and rotates synchronously with it. The locking device slides vertically on the bearing. Initially, the locking device engages with the first gear to lock it and restrict the platform's rotation. A tilting drive module is located below the turntable. The tilting drive module includes a third support, a slide, a first motor, a second gear, and a top column. The third bracket is fixedly installed on the working platform. The slide table is slidably mounted on the third bracket in the vertical direction. The first motor is fixedly mounted on the slide table. The second gear is mounted on the output shaft of the first motor. When the platform rotates above the flip drive module, the second gear is located directly below the first gear. The top column is fixedly mounted on the slide table. The slide table moves up so that the top column abuts against the locking device and lifts it up, thereby releasing the locking device from locking the first gear. At the same time, the second gear meshes with the first gear. The first motor operates to make the platform rotate controllably. After the rotation is completed, the slide table moves down so that the second gear separates from the first gear. At the same time, the locking device resets, thereby locking the platform again.

[0008] In a further preferred embodiment, a positioning disk is coaxially mounted on the second gear. A plurality of insertion holes are arranged along the circumferential direction on one side of the positioning disk. The radial distance from the axis of any of the insertion holes to the axis of the positioning disk is equal. The insertion holes are suitable for mounting positioning pins. A proximity sensor is fixedly mounted on the slide table, and the proximity sensor is adapted to the positioning pin. When the second gear rotates until the positioning pin is opposite to the proximity sensor, the first motor stops running, and the stage flips. The rotation angle of the second gear is adjusted by mounting the positioning pin in different insertion holes, thereby adjusting the flip angle of the stage.

[0009] Further preferably, a limiter is also provided on the platform, and a liftable unlocking contact is configured on the turntable. When the platform rotates above the unlocking contact, the limiter is located directly above the unlocking contact. The limiter includes a limit rod, a slide rod, an elastic element, an end cap, and a fixing pin. The slide rod passes through the platform and is adapted to slide in the vertical direction. The limit rod is fixedly disposed at the upper end of the slide rod, and the end cap is fixedly disposed at the lower end of the slide rod. The elastic element is sleeved on the slide rod and located between the platform and the end cap. A guide groove is provided on the slide rod. After passing through the platform, the fixing pin slides into the guide groove, which includes a connected axial section and a transition section. As the unlocking contact rises to abut against the end cap and continues to rise, when the fixing pin slides within the axial section, the slide rod only slides upward. When the fixing pin slides within the transition section, the slide rod rotates as it rises, and the limiting rod rises and rotates synchronously, thereby releasing the restriction on the workpiece. When the unlocking contact descends to separate from the end cap, the limiting rod resets due to the elastic force of the elastic element and the cooperation between the guide groove and the fixing pin.

[0010] As a preferred embodiment, the feeding unit is further equipped with a fixing component, which includes a fixing plate, a sliding plate, and an abutment plate. The fixing plate is fixed to the working platform, the sliding plate is slidably disposed on the fixing plate in the vertical direction, and the abutment plate is fixed to the upper side of the sliding plate. Before feeding, the sliding plate moves downward until the abutment plate presses against the workpiece on the carrier assembly and then stops. After the feeding unit completes feeding, the sliding plate resets to separate the abutment plate from the workpiece, and the carrier assembly continues to move to the next work station.

[0011] In a further preferred embodiment, the abutment plate is provided with a positioning pin, and the upper side of the carrier assembly is provided with a corresponding positioning hole. The sliding plate moves downward to allow the positioning pin to be inserted into the positioning hole, thereby achieving accurate contact between the abutment plate and the workpiece.

[0012] As a preferred embodiment, the positioning detection unit includes a fourth bracket, a moving platform, a mounting platform, a pressure rod, and a displacement sensor. The fourth bracket is fixedly mounted on the working platform. The moving platform is slidably mounted on the fourth bracket in the vertical direction. The mounting platform is slidably mounted on the moving platform in the vertical direction. The pressure rod is slidably mounted on the underside of the mounting platform in the vertical direction. The displacement sensor is mounted on the upper side of the mounting platform. The pressure rod passes through the mounting platform and abuts against the lower movable part of the displacement sensor. A through hole is provided at the bottom of the moving platform corresponding to the pressure rod. When the carrier assembly moves directly below the pressure rod, the moving platform moves down so that its bottom presses against the carrier assembly. Subsequently, the mounting platform moves down so that the pressure rod passes through the through hole and abuts against the workpiece. The mounting platform continues to move down, and the movable part is compressed. The pressure rod applies downward pressure to the workpiece to ensure that the workpiece is assembled in place. The displacement sensor detects the compression amount until a set parameter is reached. Then, the mounting platform stops moving down. After the workpiece is assembled in place, the mounting platform and the moving platform reset.

[0013] As a preferred embodiment, the unloading mechanism includes a first support platform, a two-dimensional translation platform, and a material-grabbing gripper. The first support platform is fixedly installed on the working platform, the two-dimensional translation platform is installed on the first support platform, and the material-grabbing gripper is installed on the two-dimensional translation platform. The two-dimensional translation platform is used to adjust the material-grabbing gripper in the front-back and up-down directions. Depending on whether the material-grabbing gripper picks up a qualified or unqualified workpiece, the two-dimensional translation platform adjusts the material-grabbing gripper to different unloading areas for diverting unloading.

[0014] As a preferred embodiment, the system also includes a fuel injection device, which comprises a second support platform, a mounting bracket, a shifting assembly, and a fuel injector. The second support platform is fixedly mounted on the working platform. The mounting bracket is slidably mounted on the upper side of the second support platform in the front-to-back direction. The shifting assembly is mounted on the mounting bracket. The fuel injector is slidably mounted on the shifting assembly in the up-down direction. The shifting assembly is adapted to adjust the position of the fuel injector in the up-down and left-to-right directions.

[0015] Further preferably, the displacement assembly includes a second motor, a rotating plate, a movable component, a guide plate, and a two-dimensional adjustment platform. The second motor is fixedly installed on the rear side of the mounting frame, and its output shaft passes through the mounting frame and is fixedly connected to the rotating plate. The rotating plate is provided with a waist-shaped groove. The guide plate is fixedly installed on the front side of the mounting frame and is provided with a U-shaped groove. The two-dimensional adjustment platform includes a left-right sliding assembly disposed on the front side of the mounting frame and an up-down sliding assembly disposed on the left-right sliding assembly. One end of the movable component is slidably disposed in the waist-shaped groove, and the other end passes through the U-shaped groove and is connected to the up-down sliding assembly. The operation of the second motor drives the rotating plate to rotate. Constrained by the U-shaped groove, the movable component slides along the U-shaped groove, thereby driving the up-down sliding assembly to move.

[0016] As a preferred embodiment, the carrier assembly further includes a carrier body detachably mounted on the base. A locking block is slidably disposed on the base via an elastic element, and a corresponding locking block is disposed on the carrier body. A transport mechanism is provided on the working platform. The transport mechanism includes a release component and a transport unit. A push block is provided on the release component. After the push block pushes the locking block away from the locking block, the carrier body is released from the locking limit with the base. When the push block resets, the locking block resets synchronously under the action of the elastic element. The transport unit includes a third support platform, a two-dimensional translation platform, and transport grippers. The third support platform is fixedly installed on the working platform. The second two-dimensional translation platform is installed on the third support platform. The transport gripper is installed on the second two-dimensional translation platform. The second two-dimensional translation platform is used to adjust the transport gripper in the left-right and up-down directions. The working platform is also equipped with a conveying mechanism. The conveying mechanism includes a conveying platform and a photoelectric switch. The conveying platform is fixedly installed on the working platform. The photoelectric switch is located at both ends of the conveying platform. The conveying platform is used to transport the carrier body in both directions. The transport unit is used to transport the carrier body between the conveying platform and the base.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] (1) The reflow mechanism has a compact layout and saves space: the carrier component is repositioned by two parallel straight tracks and a repositioning component at its end. During the repositioning process, the repositioning component achieves non-interference repositioning by directly pushing or pulling the carrier component into another straight track. Unlike the existing technology that uses a robotic arm for repositioning, it does not require considering the working range and increasing the length and width of the reflow mechanism to avoid interference. It also does not require considering the turning radius at the bend and increasing the width of the reflow mechanism as with the repositioning method using a circular track. The reflow mechanism of this application has a more compact layout and saves more space.

[0019] (2) The carrier component repositioning method is simple, has a short cycle, and is highly efficient: the repositioning is achieved by directly pushing or pulling the carrier component into another straight track through the repositioning component. The action is simple and the stroke is short, which avoids the problem of a long action cycle when the robot arm operates the repositioning, from grabbing the carrier component from one track to placing it into another track, thus improving the turnover efficiency of the production line.

[0020] (3) Low cost and easy maintenance: The transposition component used in this application has a simple structure, low part cost, easy assembly and maintenance, and extremely low maintenance cost. There is no need to purchase a special transposition robot, which reduces the purchase cost and the subsequent maintenance cost. Attached Figure Description

[0046] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0047] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0048] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0050] A preferred embodiment of this application, such as Figures 1 to 3 As shown, the automatic assembly production line for connectors includes: a working platform 1; a return line mechanism 2: the return line mechanism 2 is installed on the working platform 1, and several carrier components 3 are set on the return line mechanism 2; a feeding mechanism: the feeding mechanism includes several feeding units 4; an assembly mechanism: the assembly mechanism includes a rotary assembly component 5 and a linear assembly component 6. The rotary assembly component 5 includes an indexing turntable 51 and an assembly unit 52. The assembly unit 52 is equipped with a corresponding feeding unit 4. The assembly unit 52 takes materials from the feeding unit 4 and assembles them on the indexing turntable 51. After assembly, the workpiece is transferred from the indexing turntable 51 to the carrier component 3. The linear assembly component 6 includes several unloading units 61 and several arrival detection units 6. 2. Each feeding unit 61 is equipped with a corresponding feeding unit 4. The feeding unit 61 takes materials from the feeding unit 4 and places them on the corresponding workpiece for assembly. After assembly, the corresponding positioning detection unit 62 operates to ensure that the workpiece is assembled in place. The unloading mechanism 7: The unloading mechanism 7 sorts the assembled workpieces into qualified and unqualified ones for unloading. The return line mechanism 2 includes a linear track 21 and a shifting component 22. There are two linear tracks 21 arranged in parallel. The two linear tracks 21 run in opposite directions. There are two shifting components 22, which are located at the two ends of the linear tracks 21 respectively. When the carrier component 3 moves to the end of the linear track 21, the shifting component 22 pushes or pulls the carrier component 3 into the other linear track 21.

[0051] The return line mechanism 2 used in this embodiment differs significantly from existing technologies. It uses two parallel straight tracks 21 as the assembly line tracks, one for assembly and the other for return. The straight tracks 21 greatly reduce the width of the entire assembly line. Considering the motion interference of various components, the two straight tracks 21 can be brought as close together as possible. To achieve continuous operation of the entire assembly line, a specially designed shifting component 22 is set at the end of the straight tracks 21. Unlike the robot and circular track in existing technologies, it achieves shifting simply and directly by pushing or pulling the carrier component 3 that needs to be shifted directly from the current track into another track. There are no multiple steps and large spatial trajectories of robot movement, no long cycle of robot completion of shifting process, and no large turning radius limitation at the bends of circular tracks. The shifting component 22 in this embodiment adopts a minimalist approach to achieve short path, short cycle, and high efficiency shifting.

[0052] To achieve the above-mentioned technical effects, this embodiment provides a specific structure: as follows Figures 4 to 8 As shown, the linear track 21 includes a toothed belt and a fixed slide rail (not shown in the figure, but both are prior art). The shifting assembly 22 includes a first bracket 221, a second bracket 222, and a support seat 223. The first bracket 221 is fixedly installed on the work platform 1. The second bracket 222 is slidably mounted on the first bracket 221 in the vertical direction. The support seat 223 is slidably mounted on the second bracket 222 in the front-back direction. A short rail 2231 is fixedly installed on the support seat 223, and the short rail 2231 is adapted to the fixed slide rail. The carrier assembly 3 includes a base 31. A slider 311 and a slide block 312 are fixedly mounted on the lower side of the base 31. The slide blocks 311 and 312 are symmetrically arranged on the front and rear sides of the slider 311. The lower side of the slide block 312 is provided with a groove 3111 that is adapted to the short rail 2231. The lower side of the slide block 312 is provided with a toothed protrusion 3121 that is adapted to the straight toothed belt. During the operation of the return line mechanism 2, only one side of the slide block 312 is engaged with the corresponding straight toothed belt. When the carrier assembly 3 moves to the end of the straight track 21, the slider 311 slides from the fixed slide rail into the short rail 2231. The carrier seat 223 moves to separate the toothed protrusion 3121 on the engaged side from the straight toothed belt. The carrier seat 223 continues to move until the toothed protrusion 3121 on the other side is engaged with another straight toothed belt. At the same time, the short rail 2231 is connected to the fixed slide rail on that side, and the carrier assembly 3 completes the repositioning.

[0053] Understandably, the carrier 223 is used to move the carrier assembly 3 from one straight track 21 to another. Its forward and backward movement cannot be less than the distance between the two straight tracks 21. To ensure the stable operation of the production line, sufficient redundancy space can be provided. At the same time, to ensure that the carrier 223 can accurately move the carrier assembly 3, two sensors, such as photoelectric sensors, should be set on the sliding track of the carrier 223 at the positions corresponding to the two straight tracks 21. When the carrier 223 moves to the sensor position, it should stop in time to ensure accurate movement. Of course, under the premise of ensuring accuracy, the sliding track of the carrier 223 can also be set to be the same width as the two straight tracks 21, that is, when the carrier 223 is located at the end of the sliding track, it corresponds exactly to the straight track 21.

[0054] The fixed slide rail and the short rail 2231 have the same cross-sectional shape, ensuring that the carrier assembly 3 can slide from the fixed slide rail into the short rail 2231. The toothed protrusion 3121 on the lower side of the slide block 312 meshes with the straight tooth belt, so the carrier assembly 3 can slide back and forth on the straight tooth belt. Through this special structural design, the carrier assembly 3 can be pushed or pulled in in a straight line. Of course, if there is a height difference between the two straight rails 21, the second bracket 222 can slide up and down to ensure that the carrier assembly 3 can be repositioned. Obviously, during the repositioning process, the repositioning component 22 does not affect the adjacent mechanisms. It only moves in the back and forth direction and in the up and down direction at a certain height of the return line assembly, without interfering with the movement of other parts. At the same time, its movement trajectory is short and simple, which is suitable for the high-efficiency production environment of the assembly line. Compared with the existing technology, its advantages are obvious.

[0055] Obviously, the specific components of the transposition assembly 22 are multiple plates, a sliding mechanism, and a short rail 2231. These components are very common and inexpensive, and their assembly structure is quite simple, without complicated assembly. Therefore, it is low in cost and easy to maintain.

[0056] This embodiment provides a pipe fitting assembly production line. The process includes the assembly of an outer sealing ring and the assembly of an inner sealing ring. The assembly methods for the inner and outer sealing rings differ. This embodiment provides an assembly and testing scheme for the outer sealing ring. Specifically, it adopts a rotary 511 type assembly method, and the specific structural design is as follows: Figures 9 to 14As shown, the indexing rotary table 51 includes a turntable 511 and an indexing drive device 512. The indexing drive device 512 is located below the turntable 511 and controls the turntable 511 to rotate periodically and intermittently. Several tilting carriers 513 are fixedly installed on the upper side of the turntable 511. Each tilting carrier 513 includes a bearing 5131, a platform 5132, a first gear 5133, and a locking device 5134. The platform 5132 is rotatably mounted on the bearing 5131. 5133 is disposed on one side of the platform 5132 and rotates synchronously with the platform 5132. Locking device 5134 is slidably disposed on the bearing 5131 in the vertical direction. In the initial state, locking device 5134 meshes with the first gear 5133 to lock the first gear 5133, thus restricting the rotation of the platform 5132. A tilting drive module 514 is disposed below the turntable 511. The tilting drive module 514 includes a third bracket 5141, a slide table 5142, a first motor 5143, and a second gear 51. 44 and top column 5145, third bracket 5141 are fixedly installed on the working platform 1, slide table 5142 is slidably mounted on the third bracket 5141 in the vertical direction, first motor 5143 is fixedly mounted on slide table 5142, and second gear 5144 is mounted on the output shaft of first motor 5143. When the platform 5132 rotates above the flip drive module 514, the second gear 5144 is located directly below the first gear 5133. Top column 5145 is fixedly mounted on slide table 5142. The slide table 5142 moves upward, causing the top column 5145 to abut against the locking device 5134 and lift it up, thereby releasing the locking device 5134 from locking the first gear 5133. At the same time, the second gear 5144 meshes with the first gear 5133, and the first motor 5143 operates to make the platform 5132 rotate controllably. After the rotation is completed, the slide table 5142 moves downward, causing the second gear 5144 to separate from the first gear 5133. At the same time, the locking device 5134 resets, thereby locking the platform 5132 again.

[0057] Since pipe fittings come in various forms, such as straight-through fittings and directional fittings, this embodiment provides a tilting carrier 513 to accommodate different pipe fittings. The pipe fittings are fed by a feeding unit 4, such as a hoist or vibratory feeder, and then picked up by an assembly unit 52 (e.g., a robotic arm) and placed into the tilting carrier 513. Another robotic arm then picks up the outer sealing ring for assembly. In actual production, the outer sealing ring is not in its current position, so the direction of the pipe fitting needs to be adjusted. This is achieved by a rotation drive module 514. Specifically, as shown... Figure 2As shown, the hoist is located behind the indexing turntable 51. The robotic arm grabs the pipe fitting body fed by the hoist. The outer sealing ring feeding unit 4 is on the left side of the indexing turntable 51. The robotic arm grabs the outer sealing ring on the turntable 511. The installation position of the pipe fitting body is recorded as the first position, and the positions are sequentially recorded as the second position to the sixth position in a counterclockwise direction. The first position is the pipe fitting body installation position, and the third position is the outer sealing ring installation position. If necessary, the pipe fitting body may need to be rotated at a certain angle before it can be operated at the outer sealing ring installation position. Therefore, the second position is set as the rotation position. The rotation drive module 514 is located below this position. After the installation is completed at the third position, the assembled pipe fitting needs to be inspected. In this embodiment, visual inspection is used. Due to the limitations of visual inspection perspective, pipe joints in fixed positions can only be visually inspected locally. For comprehensive inspection, the pipe joints need to be flipped. Therefore, in this embodiment, the fourth station is set as the first visual inspection station, and the fifth station is the flipping station and the second visual inspection station. A flipping drive module 514 is also set below the station. At the fourth station, the camera inspects the pipe joint at this angle. After flowing to the fifth station, the flipping drive module 514 controls the tilting carrier 513 to flip, and then the camera inspects the pipe joint at this angle, realizing a complete inspection from all directions and multiple angles. Then, the sixth station is the unloading station. The semi-finished pipe joint after inspection is picked up by the robot and placed on the return line mechanism 2. Finally, the sealing ring assembly is completed.

[0058] It is understandable that when assembling the outer sealing ring at the third station, a fixed protective plate assembly can be set up to ensure assembly stability and accuracy. This assembly is fixed to the pipe fitting body during assembly by sliding horizontally and is released after assembly.

[0059] Depending on the different pipe fittings, the flipping angle varies. Therefore, to accurately set the flipping angle, this embodiment provides a specific positioning method: a positioning disk 5146 is coaxially mounted on the second gear 5144. Several insertion holes 51461 are arranged along the circumferential direction on one side of the positioning disk 5146. The radial distance from the axis of any insertion hole 51461 to the axis of the positioning disk 5146 is equal. The insertion hole 51461 is suitable for mounting a positioning pin 5147. A proximity sensor 5148 is fixedly mounted on the slide table 5142. The proximity sensor 5148 is adapted to the positioning pin 5147. When the second gear 5144 rotates until the positioning pin 5147 is opposite to the proximity sensor 5148, the first motor 5143 stops running, and the stage 5132 completes the flipping. The rotation angle of the second gear 5144 is adjusted by mounting the positioning pin 5147 in different insertion holes 51461, thereby adjusting the flipping angle of the stage 5132.

[0060] During the assembly and testing of the outer sealing ring, the tilting carrier 513 may need to be rotated multiple times. Therefore, it is necessary to ensure that the pipe fitting body is fixed on the platform 5132 throughout the entire process. Figure 12 and Figure 15 As shown, a limiter is also provided on the platform 5132, and a liftable unlocking contact 515 is configured on the turntable 511. When the platform 5132 rotates above the unlocking contact 515, the limiter is located directly above the unlocking contact 515. The limiter includes a limit rod 5135, a slide rod 5136, an elastic element 5137, an end cap 5138, and a fixing pin 5139. The slide rod 5136 passes through the platform 5132 and is adapted to slide in the vertical direction. The limit rod 5135 is fixedly installed at the upper end of the slide rod 5136, and the end cap 5138 is fixedly installed at the lower end of the slide rod 5136. The elastic element 5137 is sleeved on the slide rod 5136 and located between the platform 5132 and the end cap 5138. A guide is provided on the slide rod 5136. The fixing pin 5139 passes through the platform 5132 and slides into the guide groove. The guide groove includes a connected axial section 51361 and a transition section 51362. During the process of the unlocking contact 515 rising to abut against the end cap 5138 and continuing to rise, when the fixing pin 5139 slides in the axial section 51361, the slide rod 5136 only slides upward. When the fixing pin 5139 slides in the transition section 51362, the slide rod 5136 rotates while rising, and the limiting rod 5135 rises and rotates synchronously, thereby releasing the limitation on the workpiece. When the unlocking contact 515 descends to separate from the end cap 5138, the limiting rod 5135 resets due to the elastic force of the elastic element 5137 and the cooperation between the guide groove and the fixing pin 5139.

[0061] The aforementioned guide groove, through the setting of axial section 51361 and transition section 51362, cleverly realizes the simple up-and-down sliding of the limit rod 5135 in the initial stage and the combined motion of up-and-down sliding and horizontal rotation in the later stage. The unlocking contact 515 needs to be set at the loading and unloading stations of the pipe joint, namely the first station and the sixth station.

[0062] Of course, different types of pipe fittings may require different numbers of external sealing rings to be assembled. Therefore, more workstations can be set on the turntable 511, and more feeding units 4 and assembly units 52 can be arranged around it. The six-workstation design in this embodiment is not a specific limitation of this application. Those skilled in the art can make adjustments according to actual needs, and these adjustments all fall within the protection scope of this application.

[0063] After the pipe fittings are transferred to the return line mechanism 2, the assembly of the inner sealing rings begins. Since multiple sealing rings need to be assembled, but their assembly processes are all the same, several linear assembly assemblies 6 need to be configured on the entire return line mechanism 2. This application will not repeat the description of the linear assembly assemblies 6 for different inner sealing rings. Figure 1Also, the repetitive linear assembly component 6 is omitted.

[0064] Specifically, the feeding unit 61 is a robot; in this embodiment, a suction robot is used to pick up the inner sealing ring from the feeding unit 4. Figure 16 As shown, the feeding unit 61 is equipped with a fixing component 63, which includes a fixing plate 631, a sliding plate 632, and an abutment plate 633. The fixing plate 631 is fixed on the working platform 1. The sliding plate 632 is slidably disposed on the fixing plate 631 in the vertical direction. The abutment plate 633 is fixed on the upper side of the sliding plate 632. A positioning pin 634 is provided on the abutment plate 633. A positioning hole 321 is correspondingly provided on the upper side of the carrier assembly 3. The sliding plate 632 moves downward to allow the positioning pin 634 to be inserted into the positioning hole 321, so as to achieve accurate contact between the abutment plate 633 and the workpiece. Before feeding, the sliding plate 632 moves downward until the abutment plate 633 presses against the workpiece on the carrier assembly 3 and then stops. After the feeding unit 61 completes feeding, the sliding plate 632 resets to separate the abutment plate 633 from the workpiece, and the carrier assembly 3 continues to move to the next station.

[0065] To ensure accurate grasping by each robot or robotic arm, a vision inspection mechanism can be installed in the feeding unit 4 to assist in accurate grasping.

[0066] In this embodiment, as Figure 17 As shown, the positioning detection unit 62 includes a fourth bracket 621, a moving platform 622, a mounting platform 623, a pressure rod 624, and a displacement sensor 625. The fourth bracket 621 is fixedly mounted on the work platform 1. The moving platform 622 is slidably mounted on the fourth bracket 621 in the vertical direction. The mounting platform 623 is slidably mounted on the moving platform 622 in the vertical direction. The pressure rod 624 is slidably mounted on the lower side of the mounting platform 623 in the vertical direction. The displacement sensor 625 is mounted on the upper side of the mounting platform 623. The pressure rod 624 passes through the mounting platform 623 and abuts against the lower movable part 6251 of the displacement sensor 625. The bottom of the moving platform 622 is provided with a through hole 6221 corresponding to the pressure rod 624. When the carrier assembly 3 moves directly under the pressure rod 624, the moving platform 622 moves down so that its bottom presses against the carrier assembly 3. Then the mounting platform 623 moves down so that the pressure rod 624 passes through the through hole 6221 and abuts against the workpiece. The mounting platform 623 continues to move down, and the movable part 6251 is compressed. The pressure rod 624 applies downward pressure to the workpiece to ensure that the workpiece is assembled in place. The displacement sensor 625 detects the amount of compression until the set parameter is reached. Then the mounting platform 623 stops moving down. After the workpiece is assembled in place, the mounting platform 623 and the moving platform 622 are reset.

[0067] Understandably, after the feeding unit 61 assembles the inner sealing ring onto the pipe fitting, a slight deviation in the installation of the inner sealing ring may occur due to vibration or error. To ensure product quality and consistency, the positioning detection unit 62 operates. After the pressure rod 624 abuts against the inner sealing ring, the mounting platform 623 continues to move downward. During this process, the pressure rod 624 will exert a certain pressure on the inner sealing ring, which can compensate for the deviation and thus assemble the inner sealing ring into place. At the same time, the displacement sensor 625 detects the compression amount to ensure stroke consistency. Through the operation of the positioning detection unit 62, the deviation is compensated, and the stroke is consistent during operation, ensuring the consistency of the workpiece.

[0068] To ensure that the positioning detection unit 62 can accurately dock with the carrier assembly 3, a positioning pin 634 that matches the positioning hole 321 on the carrier assembly 3 can be set on the moving platform 622.

[0069] After being assembled from multiple linear assembly components 6, the pipe fitting completes the installation of multiple parts. After passing inspection, it enters the unloading area, where the unloading mechanism 7 diverts and unloads the materials. Figure 18 As shown, the unloading mechanism 7 includes a first support platform 71, a two-dimensional translation platform 72, and a material gripper 73. The first support platform 71 is fixedly installed on the working platform 1, the two-dimensional translation platform 72 is installed on the first support platform 71, and the material gripper 73 is installed on the two-dimensional translation platform 72. The two-dimensional translation platform 72 is used to adjust the material gripper 73 in the front-back direction and the up-down direction. Depending on whether the material gripper 73 picks up a qualified or unqualified workpiece, the two-dimensional translation platform 72 adjusts the material gripper 73 to different unloading areas for diverting unloading.

[0070] The aforementioned multiple linear assembly components 6 can be used to install multiple parts, specifically, including the installation of the lower O-ring, spacer ring, upper O-ring, and fixing ring in sequence. After the installation of the above parts is completed, before unloading, a locking spring installation station and a cap installation station can be set. These two stations are directly picked up and installed by a robot, and displacement is also detected by the positioning detection unit 62. Thus, the assembly of all components of the pipe joint is completed.

[0071] The aforementioned tests include sealing tests, which aim to ensure the effectiveness of the sealing rings. Some sealing rings may fail to meet sealing performance standards due to defects in their own components or possible deviations during assembly. Sealing tests can detect this in a timely manner, allowing materials to be diverted to non-conforming areas and ensuring production quality. Pressure tests and visual inspections can also be added as needed during the assembly process.

[0072] To ensure that the sealing ring can be assembled smoothly, such as Figures 19 to 20As shown, this embodiment also includes an oil spraying device 64, which includes a second support platform 641, a mounting frame 642, a shifting component 643, and an oil sprayer 644. The second support platform 641 is fixedly mounted on the work platform 1. The mounting frame 642 is slidably mounted on the upper side of the second support platform 641 in the front-to-back direction. The shifting component 643 is mounted on the mounting frame 642. The oil sprayer 644 is slidably mounted on the shifting component 643 in the up-down direction. The shifting component 643 is suitable for adjusting the position of the oil sprayer 644 in the up-down and left-to-right directions. The shifting component 643 includes a second motor 6431, a rotating plate 6432, a movable part 6433, a guide plate 6434, and a two-dimensional adjustment platform 6435. The second motor 6431 is fixedly mounted on the rear side of the mounting frame 642, and its output shaft passes through the mounting frame 642 and then... A rotating plate 6432 is fixedly connected and has a waist-shaped groove 64321. A guide plate 6434 is fixedly installed on the front side of the mounting frame 642 and has a U-shaped groove 64341. The two-dimensional adjustment platform 6435 includes a left-right sliding component 64351 and an up-down sliding component 64352 on the left-right sliding component 64351. One end of the movable member 6433 is slidably disposed in the waist-shaped groove 64321, and the other end passes through the U-shaped groove 64341 and is connected to the up-down sliding component 64352. When the second motor 6431 runs, it drives the rotating plate 6432 to rotate. Due to the constraint of the U-shaped groove 64341, the movable member 6433 slides along the U-shaped groove 64341, thereby driving the up-down sliding component 64352 to move.

[0073] The oil spraying device 64 is set before the lower O-ring assembly station and after the fixed ring assembly station. The first oil spraying device 64 ensures that multiple sealing rings can be assembled smoothly, and the second oil spraying device 64 ensures that the locking spring and cap can be installed smoothly.

[0074] Since the production line may need to assemble multiple types of pipe fittings, and different types of pipe fittings require corresponding carrier components 3, equipment that can replace carrier components 3 is also needed, such as... Figures 21 to 24As shown, the carrier assembly 3 also includes a carrier body 32 detachably mounted on the base 31. A locking block 313 is slidably disposed on the base 31 via an elastic element, and a corresponding locking block 322 is disposed on the carrier body 32. A transport mechanism 8 is disposed on the work platform 1. The transport mechanism 8 includes a release assembly 82 and a transport unit 81. A push block 821 is disposed on the release assembly 82. After the push block 821 pushes the locking block 313 away from the locking block 322, the carrier body 32 is released from the locking limit with the base 31. When the push block 821 resets, the locking block 313 is simultaneously reset by the action of the elastic element. The transport unit 81 includes a third support platform 811, a two-dimensional translation platform 812, and a transport gripper. 813, the third support platform 811 is fixedly installed on the working platform 1, the second two-dimensional translation platform 812 is installed on the third support platform 811, and the transport gripper 813 is installed on the second two-dimensional translation platform 812. The second two-dimensional translation platform 812 is used to adjust the transport gripper 813 in the left and right directions and the up and down directions. The working platform 1 is also equipped with a conveying mechanism 9, which includes a conveying platform 91 and a photoelectric switch 92. The conveying platform 91 is fixedly installed on the working platform 1, and the photoelectric switch 92 is set at both ends of the conveying platform 91. The conveying platform 91 is used to transport the carrier body 32 in both directions, and the transport unit 81 is used to transport the carrier body 32 between the conveying platform 91 and the base 31.

[0075] In this embodiment, the carrier assembly 3 is designed as a detachable carrier body 32 and base 31. The base 31 always rotates on the return line mechanism 2. The carrier body 32 is fixed by the cooperation of the snap-fit ​​block 313 and the snap-fit ​​block 322. When a change of type is required, the original carrier body 32 only needs to be removed by the transport unit 81 and the new carrier body 32 installed to replace the carrier body 32 of the entire production line, so that production can proceed smoothly. Through the cooperation of the transport mechanism 8 and the conveying mechanism 9, automated changeover can be achieved quickly and accurately without manual operation.

[0076] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
