Description

Technical Field

[0001] This utility model relates to the field of cable connector assembly technology, and more specifically to an automatic cable connector assembly device. Background Technology

[0002] A cable connector is a waterproof connector that maintains stable electrical connections in humid, wet, or underwater environments. A cable connector includes a main body housing, a waterproof ring, a clamping jaw, a nut, an inner O-ring, and an outer O-ring. The inner O-ring is fitted over the clamping jaw, which is housed inside the main body housing. The waterproof ring is housed inside the clamping jaw. The nut is screwed onto one end of the main body housing, confining the inner O-ring, clamping jaw, and waterproof ring together within the main body housing. The outer O-ring is fitted over the main body housing. This assembly allows for the assembly of the cable connector.

[0003] In existing technology, workers need to manually install and fix the clamping claws, inner O-rings, outer O-rings, waterproof rings, and nuts onto the main body shell in sequence to complete the assembly of the cable connector. However, the long-term repetitive and monotonous operation of assembling cable connectors makes workers prone to fatigue and errors, reducing the product qualification rate. At the same time, manual assembly is inefficient and has high labor costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assembly equipment with a high degree of automation and easy assembly of cable connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic cable connector assembly device, comprising a positioning component, a clamping claw feeding component, an inner O-ring feeding component, a main body feeding component, a main body pressing component, an outer O-ring feeding component, a flipping component, a waterproof ring feeding component, a nut feeding component, and a discharging component;

[0006] The positioning assembly includes a base supporting various components, a turntable rotatably connected to the base, multiple workstations circumferentially distributed around the turntable axis, and a stationary plate coaxial with the turntable and fixed relative to the base. The multiple workstations include, sequentially distributed along the turntable edge and corresponding to the clamping claw loading assembly, inner O-ring loading assembly, main body loading assembly, main body pressing assembly, outer O-ring loading assembly, flipping assembly, waterproof ring loading assembly, nut loading assembly, and unloading assembly, respectively. The turntable sequentially moves the clamping claws at the clamping claw loading stations to each component, assembling and collecting the clamping claws, inner O-rings, main body shell, outer O-rings, waterproof rings, and nuts together.

[0007] As a further improvement of this utility model, the waterproof ring feeding assembly includes a waterproof ring feed channel driven by a vibrator, an end seat connected to one end of the waterproof ring feed channel, a clamping seat located on the other side of the end seat relative to the waterproof ring feed channel, multiple clamping blocks arranged in a circle and connected above the clamping seat, a common clamping cylinder for driving the multiple clamping blocks to move towards each other, a clamping cylinder for partially clamping the waterproof ring at the end of its output shaft, a waterproof ring feeding cylinder that moves synchronously with the clamping cylinder, a feed cylinder through which the output shaft of the waterproof ring feeding cylinder passes and for clamping the waterproof ring, a translation cylinder for driving the clamping cylinder to move horizontally, and a vertical cylinder for driving the translation cylinder to move up and down. The clamping cylinder moves the waterproof ring from the end seat to the clamping seat so that the multiple clamping blocks can clamp the waterproof ring together. The waterproof ring feeding cylinder moves the waterproof ring at the clamping seat to the waterproof ring feeding station.

[0008] As a further improvement of this utility model, the card holder includes a base connected to the base, multiple base columns standing above the base, and a top seat positioned above the multiple base columns and elastically connected to multiple clamping blocks. The center of the base is provided with a top-lifting cylinder with an output end for supporting the waterproof ring. The number of the co-clamping cylinders is multiple and they are distributed circumferentially around the top-lifting cylinders. The output shafts of the multiple co-clamping cylinders are provided with push rods that penetrate the top seat and can drive the clamping blocks to move along the circumferential diameter of the multiple clamping blocks.

[0009] As a further improvement of this utility model, it also includes a rotating pressing component located between the flipping component and the waterproof ring feeding component. The multiple workstations also include a pre-support workstation corresponding to the rotating pressing component. The rotating pressing component includes a rotating cylinder located directly above the pre-support workstation, a pre-tension spring sleeved outside the output shaft of the rotating cylinder, a support sleeve positioned at the end of the pre-tension spring and into which the output shaft of the rotating cylinder extends, and a pre-support cylinder that drives the rotating cylinder to move up and down. The support sleeve is provided with multiple support plates at the port facing the pre-support workstation, which can elastically deform relative to the support sleeve and block the port of the support sleeve. The multiple support plates are all inclined relative to the vertical plane. The output shaft of the rotating cylinder opens the multiple support plates so that the multiple support plates can fit against the inner wall of the clamping claw.

[0010] As a further improvement of this utility model, the plurality of workstations also include a waterproof ring pressing workstation located between the waterproof ring loading workstation and the nut loading workstation, and the stationary plate is provided with a waterproof ring pressing cylinder corresponding to the waterproof ring pressing workstation and used to press the waterproof ring into place.

The diameter of the circumference of the outer wall of the multiple feeding columns matches the inner diameter of the push ring. The push ring pushes the O-rings tightened outside the multiple feeding columns away from the feeding columns, so that the O-rings are tightened outside the clamping jaws or the main body shell.

[0012] As a further improvement of this utility model, it also includes a rotary positioning component located between the clamping claw feeding component and the inner O-ring feeding component. The plurality of workstations also include a correction workstation corresponding to the rotary positioning component. The rotary positioning component includes a rotating claw cylinder located directly above the correction workstation, a pressure spring sleeved outside the output shaft of the rotating claw cylinder, a rotation limiting sleeve positioned at the end of the pressure spring and through which the output shaft of the rotating claw cylinder passes, and a linear cylinder that drives the rotating claw cylinder to move up and down. The rotation limiting sleeve is provided with a rotation limiting groove into which the end of the clamping claw extends and restricts the rotation of the clamping claw. The rotation of the clamping claw is driven by the output shaft of the rotating claw cylinder so that the rotation limiting sleeve can be sleeved outside the clamping claw under the action of the pressure spring.

[0013] As a further improvement of this utility model, it also includes a limiting component positioned on the stationary plate and corresponding to the inner O-ring feeding station. The limiting component includes a thumb cylinder that can hold the clamping claw and a limiting cylinder that drives the thumb cylinder to move radially along the stationary plate.

[0014] As a further improvement of this utility model, the main pressing assembly includes a pressing cylinder located directly above the pressing station and fixed relative to the base, a support cylinder located directly below the pressing station and fixedly connected to the base, and a support plate located on the output shaft of the support cylinder.

[0015] As a further improvement of this utility model, each of the multiple workstations is provided with a claw seat and a shell seat arranged side by side for clamping claws and main body shells to be inserted. The flipping assembly includes a lifting cylinder fixed relative to the base, a rotating cylinder positioned on the output shaft of the lifting cylinder, and a clamping cylinder eccentrically connected to the output shaft of the rotating cylinder. The main body shell at the claw seat is clamped by the clamping cylinder, and the main body shell is flipped and inserted into the shell seat under the drive of the lifting cylinder and the rotating cylinder.

[0016] The beneficial effects of this utility model are as follows: The clamping claws at the clamping claw loading station are sequentially driven to each component by the turntable, so that the clamping claws, inner O-ring, main body shell, outer O-ring, waterproof ring and nut are assembled together and collected. Compared with the manual assembly method, this design realizes the automation of assembling cable connectors, with a high degree of automation, reducing labor costs, and effectively making up for the defects of manual assembly that cause fatigue and easy errors for workers, thereby improving the qualification rate of cable connectors.

The outer wall of the push ring 36 has an integrally formed lug and the lug is fixedly connected to the output shaft of the O-ring feeding cylinder 35.

[0033] Specific reference Figure 5 As shown, the main pressing assembly 5 includes a pressing cylinder 51, a supporting cylinder 52, and a supporting plate 53. Both the pressing cylinder 51 and the supporting cylinder 52 are linear cylinders. The pressing cylinder 51 is fixedly connected to the base 11 by a bracket. The pressing cylinder 51 is positioned directly above the pressing station 134 with its output shaft facing downward. The supporting cylinder 52 is positioned on the base 11 and below the pressing station 134 with its output shaft facing upward. The supporting plate 53 is generally frustum-shaped and its small end is fixedly connected to the output shaft of the supporting cylinder 52.

[0034] Specific reference Figure 6 As shown, the flipping assembly 7 includes a lifting cylinder 71, a rotating cylinder 72, and a clamping cylinder 73. The lifting cylinder 71 is positioned on the base 11 by a bracket and the output shaft of the lifting cylinder 71 is vertically downward. The cylinder body of the rotating cylinder 72 is fixedly connected to the output shaft of the lifting cylinder 71. The cylinder body of the clamping cylinder 73 is fixedly connected to the output shaft of the rotating cylinder 72 and the clamping cylinder 73 is eccentrically set relative to the rotation center of the rotating cylinder 72.

[0035] Specific reference Figure 7As shown, the waterproof ring feeding assembly 8 includes a waterproof ring feed channel 81, an end seat 82, a clamping seat 83, multiple clamping blocks 84, a co-clamping cylinder 85, a clamping cylinder 86, a waterproof ring feeding cylinder 87, a feed cylinder 88, a translation cylinder 89, and a vertical cylinder 80. A vertical vibrator is fixedly installed on the base 11, and the waterproof ring feed channel 81 is positioned on the vertical vibrator. One end of the waterproof ring feed channel 81 can be externally connected to a vibrating plate containing a waterproof ring, and the other end of the waterproof ring feed channel 81 is connected to the end seat 82. The end seat 82 is fixedly connected to the base 11, and the end seat 82 has a groove for accommodating the waterproof ring. The depth of the groove is less than the height of the waterproof ring. The clamping seat 83 is fixedly connected to the straight line where the waterproof ring feed channel 81 and the end seat 82 are located. A bracket positioned on the base 11 is provided on one side of the clamping seat 83, and a cylinder that can drive the clamping cylinder 86 and the waterproof ring feeding cylinder 87 to move horizontally simultaneously is fixedly connected to the bracket. The translation cylinder 89 and the vertical cylinder 80 that drives the horizontal cylinder 89 to move up and down are provided. The output shaft of the clamping cylinder 86 is machined with a groove for partial clamping of the waterproof ring. The inner cavity of the groove is frustoconical and the large end is located on the end face of the groove. The material cylinder 88 is fixedly connected to the cylinder body of the waterproof ring feeding cylinder 87 through a connecting plate. The material cylinder 88 is sleeved outside the output shaft of the waterproof ring feeding cylinder 87. The material cylinder 88 is cut along the length of the material cylinder 88 from the downward end face to form a gap groove on the cylinder wall. The inner diameter of the material cylinder 88 is smaller than the outer diameter of the waterproof ring. The part of the inner wall of the material cylinder 88 near the end face is chamfered to facilitate the smooth entry of the waterproof ring into the material cylinder 88. Multiple clamping blocks 84 are all confined on the clamping seat 83. The number of clamping cylinders 85 is the same as the number of clamping blocks 84. The clamping cylinders 85 are linear cylinders and the output shaft of the clamping cylinders 85 can be directly connected to the clamping blocks 84.

[0036] The nut feeding assembly 9 is the same as the prior art, which includes a material channel for transporting nuts and a robot for feeding nuts to the nut feeding station 138 and screwing the nuts onto the main body shell;

[0037] The unloading assembly 10 is the same as the prior art, including a collection box positioned on the base 11 and a robotic arm that clamps the product at the unloading station 139 to the collection box;

[0038] In the initial state, the O-ring manipulator 34 and the O-ring feeding cylinder 35 are located directly above the feeding seat 32 and the four-jaw chuck 33, respectively. The drive shafts of the four-jaw chuck 33 are all far apart, so that the diameter of the circumference of the four support rods is larger than the diameter of the circumference of the multiple feeding columns 37 or the outer diameter of the material cylinder 88. The four support rods together open an O-ring. The pressing cylinder 51 and the support plate 53 are both far away from the pressing station 134. The output shaft of the clamping cylinder 73 is located above the claw seat at the flipping station 136. The clamping cylinder 86 and the waterproof ring feeding cylinder 87 are located directly above the end seat 82 and the chuck seat 83, respectively. A waterproof ring is placed on the end seat 82 and the chuck seat 83. The manipulators of the clamping claw feeding assembly 2, the main body feeding assembly 4 and the nut feeding assembly 9 are all located above the corresponding material channels. The manipulator of the unloading assembly 10 is located above the unloading station 139. The power is turned on and the relevant processing operations are performed. The assembly steps of the cable connector are as follows:

[0039] Step 1: The clamping claw loading assembly 2 uses a robotic arm to grab the clamping claws on the corresponding material channel to the clamping claw loading station 131, with one end of the clamping claw extending into the claw seat;

[0040] In the second step, the turntable 12 rotates at a certain angle, causing the clamping claws to move from the clamping claw loading station 131 to the inner O-ring loading station 132. The inner O-rings are transported by the vibratory feeder and the inner O-ring material channel 31 to the feeding seat 32. The O-ring robot arm 34 and the O-ring loading cylinder 35 both move downwards to their positions. The grippers of the O-ring robot arm 34 extend into the feeding seat 32 and clamp the inner O-rings. Multiple loading columns 37 are inserted into the inner cavity surrounded by multiple support rods. The drive shafts of the four-jaw chuck 33 move closer together and retract to the inside of the circumference of the multiple loading columns 37. The inner O-rings are tightened outside the multiple loading columns 37. Then, the O-ring robot arm 34 and the O-ring loading cylinder 35 are reset. The inner O-rings in the O-ring material channel 31 enter the feeding seat 32 for the next clamping. Then, the O-ring robot arm 34 and the O-ring loading cylinder 35 move horizontally to their positions. The O-ring manipulator 34 and the O-ring loading cylinder 35 are located directly above the four-jaw chuck 33 and the inner O-ring loading station 132, respectively. Then, the O-ring manipulator 34 and the O-ring loading cylinder 35 move downwards into place. The four support rods of the four-jaw chuck 33 pass through the inner O-ring held by the O-ring manipulator 34. One end of the clamping jaws passes into the circumference of the multiple loading columns 37. Then, the O-ring loading cylinder 35 drives the push ring 36 to move downwards, causing the inner O-ring to be pushed away from the loading column 37 and retracted on the outer wall of the clamping jaws. The O-ring manipulator 34 releases the O-ring, causing the inner O-ring to fall onto the drive shaft of the four-jaw chuck 33. Finally, the push ring 36 resets first, and the O-ring manipulator 34 and the O-ring loading cylinder 35 reset later. The drive shafts of the four-jaw chuck 33 move away from each other, causing the four support rods to open the inner O-ring in preparation for the next removal with the help of the loading column 37.

[0041] The third step is to rotate the turntable 12 at a certain angle so that the clamping claw with the inner O-ring moves from the inner O-ring feeding station 132 to the main body feeding station 133. The main body feeding component 4 uses the robot to clamp the main body shell in the corresponding material channel to the main body feeding station 133. The part of the clamping claw with the inner O-ring is covered by the main body shell, and then the robot resets.

[0042] Step 4: The turntable 12 rotates at a certain angle, causing the clamping claw containing the main body shell to move from the main body loading station 133 to the pressing station 134. The support cylinder 52 drives the support plate 53 to move upward, so that the support plate 53 touches the lower surface of the turntable 12. Then, the output axis of the pressing cylinder 51 moves downward and presses the main body shell downward. The main body shell moves linearly relative to the clamping claw and engages with the clamping claw. Then, the pressing cylinder 51 and the support cylinder 52 reset one after another.

[0043] Step 5: Rotate turntable 12 at a certain angle to move the main body shell with clamping claws in place from the pressing station 134 to the outer O-ring feeding station 135. Since the outer O-ring feeding assembly 6 and the inner O-ring feeding assembly 3 have roughly the same structure, the difference is that the inner diameter of the feeding column 37 of the outer O-ring feeding assembly 6 is matched with the outer diameter of the main body shell. Repeat the inner O-ring feeding action in step 2 to make the outer O-ring fit outside the main body shell.

[0044] Step 6: The turntable 12 rotates at a certain angle, causing the main body shell, which has been clamped by the clamping claws, to move from the outer O-ring feeding station 135 to the flipping station 136. The lifting cylinder 71 drives the rotating cylinder 72 and the clamping cylinder 73 to move downwards into place as a whole. Then, the clamping cylinder 73 clamps the main body shell. Next, the lifting cylinder 71 resets, and the main body shell is released from the claw seat. Then, the rotating cylinder 72 drives the clamping cylinder 73 and the main body shell to flip 180 degrees so that the main body shell is directly above the shell seat with the clamping claws facing upwards. Immediately afterwards, the lifting cylinder 71 drives the rotating cylinder 72, the clamping cylinder 73 and the main body shell to move downwards into place as a whole. The clamping cylinder 73 releases the main body shell, and the main body shell is partially accommodated in the shell seat. Finally, the lifting cylinder 71 and the rotating cylinder 72 reset one after the other.

[0045] Step 7: The turntable 12 rotates at a certain angle, moving the rotated main body shell from the flipping station 136 to the waterproof ring loading station 137. The waterproof ring is transported by the vibrating plate and the waterproof ring material channel 81 to the end seat 82. One side of the waterproof ring is attached to the groove wall of the end seat 82, and its upward end is higher than the plane of the upper surface of the end seat 82. Driven by the vertical cylinder 80, the clamping cylinder 86 and the waterproof ring loading cylinder 87 move downward into place. The output shaft end face of the clamping cylinder 86 is aligned with the upper surface of the end seat 82. The surface contacts the top, and the upper end of the waterproof ring in the end seat 82 is engaged with the end of the output shaft of the engagement cylinder 86. The waterproof ring on the engagement seat 83 enters the material cylinder 88, and the material cylinder 88 is partially opened by the waterproof ring. Then, the vertical cylinder 80 resets, and the waterproof rings in the end seat 82 and the engagement seat 83 move upward with the engagement cylinder 86 and the material cylinder 88, respectively. The waterproof ring in the waterproof ring channel 81 enters the end seat 82 so that it can be engaged with the output shaft of the engagement cylinder 86 next time. The translation cylinder 89 drives the engagement cylinder 86 and the waterproof ring. The feeding cylinder 87 moves radially along the turntable 12 until the clamping cylinder 86 and the waterproof ring feeding cylinder 87 are respectively located above the clamping seat 83 and the waterproof ring feeding station 137. The vertical cylinder 80 drives the clamping cylinder 86 and the waterproof ring feeding cylinder 87 to move downwards into position. The waterproof ring at the end of the output shaft of the clamping cylinder 86 is located at the center of multiple clamping blocks 84. The material cylinder 88 is coaxial with the clamping claw and close to the clamping claw. Then, multiple clamping cylinders 85 drive the corresponding clamping blocks 84 to move towards the center of the clamping seat 83 until multiple Clamping blocks 84 clamp the waterproof ring on the output shaft of clamping cylinder 86. At the same time, the output shaft of waterproof ring feeding cylinder 87 moves downward relative to the material cylinder 88 and pushes the waterproof ring away from the material cylinder 88. The waterproof ring enters the inner cavity of the clamping claw. The output shaft of waterproof ring feeding cylinder 87 resets. Then, vertical cylinder 80 and translation cylinder 89 reset one after another. The waterproof ring on the output shaft of clamping cylinder 86 disengages from the slot. Finally, multiple clamping cylinders 85 drive the corresponding clamping blocks 84 to reset. The released waterproof ring stops at the center position of the card seat 83.

[0046] Step 8: The turntable 12 rotates at a certain angle so that the main body shell with the waterproof ring is moved from the waterproof ring feeding station 137 to the nut feeding station 138. The robot arm clamps the nut in the material channel to the upper end of the main body shell and screws it onto the outside of the end of the main body shell. Then the robot arm resets.

[0047] Step 9: Turntable 12 rotates at a certain angle so that the main body shell with nuts is moved from nut loading station 138 to unloading station 139. The robot arm clamps the main body shell at unloading station 139 above the collection box. Then the robot arm releases the main body shell, and the main body shell falls into the collection box. Finally, the robot arm resets.

[0048] Step 10: Rotate turntable 12 at a certain angle so that the main body shell with nuts is moved from unloading station 139 to clamping claw loading station 131. Repeat the above nine steps to assemble the cable connectors one by one.

[0049] Compared to manual assembly, this design automates the assembly of cable connectors, resulting in a high degree of automation, reduced labor costs, and effectively compensates for the fatigue and error-prone nature of manual assembly, thereby improving the pass rate of cable connectors.

[0050] The main body pressing component 5 provides support for the turntable 12 through the support cylinder 52 and the support plate 53, so that the turntable 12 cannot tilt when the pressing cylinder 51 presses down on the main body shell, ensuring that the turntable 12 always remains in a horizontal state, which is conducive to the balance of the turntable 12 rotation.

[0051] As one specific implementation method of the improvement, please refer to the following: Figure 7 As shown, the card holder 83 includes a base 831, four base pillars 832, and a top seat 833. The base 831 is fixedly connected to the base 11. The four base pillars 832 are fixedly connected to the four corners of the base 831 and are in a vertical position. The top seat 833 is fixedly connected to the upward-facing ends of the four base pillars 832. There are four clamping blocks 84. A through groove is machined at the center of the top seat 833. Four slots are machined on the top seat 833, all of which are circumferentially distributed around the through groove. One end of a spring is positioned on the bottom of the slot, and the length direction of the spring is the same as the diameter direction of the circumference of the four slots. Grooves are machined on the opposite sides of the slots. Slider blocks are integrally formed on both sides of the clamping block 84 and are respectively inserted into the grooves. The two slot walls of the clamping block 84 without sliders are respectively machined with clamping parts and beveled surfaces that can penetrate the slot walls. The clamping block 84 is inserted into the slot along the diameter of the circumference of the slot. The sliders on both sides of the clamping block 84 are located in the corresponding grooves and the clamping part of the clamping block 84 is inserted into the groove wall of the through groove. The bottom of the clamping block 84 is machined with a stepped surface and contacts the other end of the spring. A lifting cylinder 834 is fixedly connected at the center of the base 831. The lifting cylinder 834 is a linear cylinder and the cylinder body stands on the base 831. The output shaft end of the lifting cylinder 834 is located in the through groove. Two co-clamping cylinders 85 distributed around the lifting cylinder 834 are also fixedly connected on the base 831. The output shafts of the two co-clamping cylinders 85 are fixedly connected with crossbars at both ends located below the two adjacent clamping blocks 84. Push rods 835 penetrating the top seat 833 are erected at both ends of the crossbars. The ends of the push rods 835 that protrude from the top seat 833 are machined with sliding surfaces that can slide relative to the inclined surface.

[0052] In the seventh step of the first embodiment, after the material cylinder 88 moves downward into place, the lifting cylinder 834 pushes the waterproof ring at the end of the output shaft into the material cylinder 88. Then the lifting cylinder 834 resets. After the clamping cylinder 86 moves downward into place, the lifting cylinder 834 remains stationary. The output shafts of the two co-clamping cylinders 85 move upward. The four push rods 835 move upward relative to the corresponding clamping blocks 84. The four clamping blocks 84 move towards each other and clamp the waterproof ring with the clamping part. The spring is compressed and deformed. After the clamping cylinder 86 separates from the waterproof ring, the two co-clamping cylinders 85 drive the push rods 835 to reset. The four clamping blocks 84 move away from each other under the push of the spring. The released waterproof ring is located on the end face of the output shaft of the lifting cylinder 834.

[0053] Compared to the design where the co-clamping cylinder 85 is positioned on the top seat 833 and directly connected to the clamping block 84, this design can reduce the size of the top seat 833, reduce the area occupied, and make the structure more compact. At the same time, it can make up for the defect of deformation of the waterproof ring caused by the large force generated by the co-clamping cylinder 85 directly driving the clamping block 84 to clamp the waterproof ring, and ensure the stability of the waterproof ring structure. The design of the lifting cylinder 834 can ensure that the waterproof ring is completely inserted into the material cylinder 88. Compared with the design where one co-clamping cylinder 85 drives two clamping blocks 84 to move, the design of one co-clamping cylinder 85 drives one clamping block 84 to move can reduce the number of co-clamping cylinders 85 and reduce the cost of use.

[0054] As one specific implementation method of the improvement, please refer to the following: Figure 10As shown, it also includes a rotating pressing component c0 located between the flipping component 7 and the waterproof ring feeding component 8. Multiple workstations 13 also include pre-support workstations c13 corresponding to the rotating pressing component c0. The rotating pressing component c0 includes a rotating cylinder c1, a pre-tensioning spring c2, a support sleeve c3, and a pre-supporting cylinder c4. The rotating cylinder c1 is a rotary cylinder, and the pre-supporting cylinder c4 is a linear cylinder. Multiple support plates c5 are integrally formed at one end of the support sleeve c3. All support plates c5 can elastically swing relative to the edge of the support sleeve c3's end. During assembly, the pre-supporting cylinder c4 is positioned on the base 11 by its diameter, and the rotating cylinder... The cylinder body of C1 is fixedly connected to the output shaft of the pre-support cylinder C4. The output shaft of the rotating cylinder C1 faces the pre-support station C13. The pre-tension spring C2 is sleeved outside the output shaft of the rotating cylinder C1, and one end of the pre-tension spring C2 is fixedly connected to the output shaft of the rotating cylinder C1. The support sleeve C3 is sleeved outside the output shaft of the rotating cylinder C1, and the port of the support sleeve C3 is welded to one end of the pre-tension spring C2. Multiple support plates C5 are located below the output shaft of the rotating cylinder C1 and cover the port of the support groove C3. After the main body shell, after being rotated by the turntable 12, moves from the rotating station 136 to the pre-support station C13, the pre-support cylinder C4 drives the rotating cylinder C1 vertically downward. As the cylinder moves downwards, multiple support plates c5 partially extend into the clamping jaws, opening the jaw ports. Because the clamping jaws are no longer opened, they push the support sleeve c3 to move linearly relative to the output shaft of the cylinder c1. The preload spring c2 is compressed, and the output shaft of the cylinder c1 contacts the multiple support plates c5, causing them to swing outwards relative to the ports of the support sleeve c3. The contact area between the multiple support plates c5 and the inner wall of the clamping jaws increases and they become closer together. Once the cylinder c1 is in position, the output shaft of the cylinder c1, the preload spring c2, the support sleeve c3, the clamping jaws, and the main body shell rotate synchronously. After rotation to the final position... The pre-support cylinder C4 drives the rotating cylinder C1 to reset, and the pre-tension spring C2 and the support sleeve C3 reset sequentially relative to the output shaft of the rotating cylinder C1. This design allows the clamping claw and the main body shell to rotate relative to the housing while adjusting their positions, ensuring that the clamping claw and the main body shell are coaxial with respect to the housing, which facilitates the subsequent installation of the waterproof ring. At the same time, the port of the clamping claw is opened, which facilitates the smooth entry of the waterproof ring into the clamping claw. Furthermore, if the clamping claw and the main body shell rotate relative to each other due to loosening during the rotation process, it is convenient to classify and collect the main body shells that are not properly engaged, saving subsequent assembly operations and reducing the waste of parts.

[0055] As one specific implementation of the improvement, since the function of the waterproof ring feeding cylinder 87 is only to push the waterproof ring away from the material cylinder 88, and it cannot ensure whether the waterproof ring is properly installed in the clamping jaws, in order to solve the aforementioned problem, please refer to the following: Figures 1 to 3As shown, the multiple stations 13 also include a waterproof ring pressing station d13 located between the waterproof ring loading station 137 and the nut loading station 138. The stationary plate 14 is equipped with a waterproof ring pressing cylinder d0 corresponding to the waterproof ring pressing station d13 and used to press the waterproof ring into place. When the main body shell containing the waterproof ring moves to the waterproof ring pressing station d13, the output shaft end of the waterproof ring pressing cylinder d0 extends into the inner cavity of the clamping claw and presses down the waterproof ring. Then the waterproof ring pressing cylinder d0 resets. This design can ensure that the waterproof ring is locked in place in the inner cavity of the clamping claw, making up for the defect that the waterproof ring moves randomly in the inner cavity of the clamping claw and affects the cable passage.

[0056] As an improved specific implementation, since multiple protrusions are integrally formed on the outer wall of the clamping claw, and the states of the clamping claw at the clamping claw loading station 131 are different, the multiple loading columns 37 at the inner O-ring loading assembly 3 are prone to contacting the protrusions when moving downwards, thus affecting the assembly of the inner O-ring. To solve the aforementioned problem, please refer to the following specific implementation. Figure 8As shown, a rotary positioning component a0 is provided between the clamping jaw feeding assembly 2 and the inner O-ring feeding assembly 3. Multiple workstations 13 also include a correction workstation a13 corresponding to the rotary positioning component a0. The rotary positioning component a0 includes a rotating jaw cylinder a1, a pressure spring a2, a rotation limiting sleeve a3, and a linear cylinder a4. The rotating jaw cylinder a1 is a rotary cylinder. The end face of the rotation limiting sleeve a3 is machined with a rotation limiting groove a5 for the clamping jaw end to insert into. The inner contour of the rotation limiting groove a5 can match the contour of the clamping jaw end face. During assembly, linear cylinder a4 is positioned on base 11 via a bracket. Then, rotary claw cylinder a1 is fixedly connected to the output shaft of linear cylinder a4 via a connecting bracket, with the output shaft of rotary claw cylinder a1 facing the correction station a13. A downward pressure spring a2 is sleeved around the output shaft of rotary claw cylinder a1, with one end of the spring fixedly connected to the output shaft. One end of the unprocessed limiting groove a5 of the limiting sleeve a3 is sleeved around the output shaft of rotary claw cylinder a1 and welded to one end of the downward pressure spring a2. The rotary table 12 then rotates the cylinder. After the clamping jaw moves from the clamping jaw loading station 131 to the calibration station a13, the linear cylinder a4 drives the rotary jaw cylinder a1 to move vertically downwards into position. If the end face of the clamping jaw is not aligned with the rotation limiting groove a5, the end face of the clamping jaw will not engage with the rotation limiting groove a5 and will instead contact the end face of the rotation limiting sleeve a3. The rotation limiting sleeve a3 will move linearly relative to the output shaft of the rotary jaw cylinder a1, compressing the pressure spring a2. Then, the output shaft of the rotary jaw cylinder a1 will drive the pressure spring a2 and the rotation limiting sleeve a3 to rotate relative to the clamping jaw until the rotation limiting groove a5 and the end face of the clamping jaw are aligned. With the part facing each other, the downward pressure spring a2 pushes the rotation limiting sleeve a3 downward, and the end of the clamping claw inserts into the rotation limiting groove a5. As the output shaft of the rotating claw cylinder a1 continues to rotate, the clamping claw rotates with the rotation limiting sleeve a3. After the clamping claw rotates to the position, the linear cylinder a4 drives the rotating claw cylinder c1 to reset, and the clamping claw separates from the rotation limiting sleeve a3. This design can rotate the clamping claws in different states to the same state, ensuring that the subsequent multiple feeding columns 37 do not interfere with the protrusions on the outer wall of the clamping claw, which is conducive to the smooth engagement of the inner O-ring on the designated position on the outer wall of the clamping claw.

[0057] As an improved implementation, in the second step of the first embodiment, because the distance by which the vertical cylinder drives the O-ring feeding cylinder 35 to move downward cannot be precisely controlled, there is a situation where the O-ring feeding cylinder 35 moves downward too much, causing the inner O-ring to fail to be fitted into the designated position. To solve the aforementioned problem, please refer to [the relevant documentation]. Figure 9As shown, it also includes a limiting component b0 positioned on the stationary plate 14 and corresponding to the inner O-ring loading station 132. The limiting component b0 includes a thumb cylinder b1 capable of clamping the clamping claw and a limiting cylinder b2 that drives the thumb cylinder b1 to move radially along the stationary plate 14. The limiting cylinder b2 is a linear cylinder. In the initial state, the two output shafts of the thumb cylinder b1 are far apart. After the clamping claw moves to the inner O-ring loading station 132, the limiting cylinder b2 drives the thumb cylinder b1 to move toward the clamping claw and stop. The two output shafts of the thumb cylinder b1 are located on both sides of the clamping claw. Subsequently, the two output shafts of the thumb cylinder b1 move toward each other and clamp the clamping claw. Performing the second step of the first embodiment, the multiple feeding columns 37 move to the position where the output shaft of the thumb cylinder b1 touches the column and remain stationary. The output shafts of the thumb cylinder b1 move away from each other and reset. The limit cylinder b2 drives the thumb cylinder b1 to return to its initial state. The O-ring feeding cylinder 35 drives the push ring 36 to push the inner O-ring outside the feeding column 37 away from the feeding column 37, so that the inner O-ring is tightened at the designated position of the clamping claw. Subsequently, the O-ring feeding cylinder 35 drives the push ring 36 to reset and the O-ring feeding cylinder 35 resets with the vertical cylinder. This design can improve the accuracy of the inner O-ring being tightened on the clamping claw and improve the product qualification rate.
