All other embodiments that a person skilled in the art can achieve without inventive effort based on the embodiments in the present application are to fall within the scope of protection of the present application.

[0010] With reference to Fig. In the description of the present application, a phase adjuster 900 is a mature technology in the prior art, wherein the assembly line 100 for phase adjusters is used to assemble the phase adjuster 900. The phase adjuster 900 represents an important component of the variable valve control system and comprises a pole tube assembly 910 and a coil assembly 920. The pole tube assembly 910 further comprises an armature pin assembly 918, which can move along its axial direction. The armature pin assembly 918 comprises a detent pin 911, a ball 912, and an armature 913. Under the action of the coil assembly 920, the armature pin assembly 918 can be ejected outwards in the pole tube assembly 910 to act on an oil control valve.

[0011] With reference to Fig. 1 The assembly line 100 for phase adjusters according to an embodiment of the present application comprises a detent pin-anchor assembly device 200, a pole tube assembly device 300 and a phase adjuster assembly device 400, wherein the detent pin-anchor assembly device 200 is used to form an anchor pin assembly 918, wherein the detent pin-anchor assembly device 200 further comprises a detent pin assembly device 210 and an anchor pin assembly device 220.

[0012] With reference to Fig. 23, Fig. 24 and Fig. 25, the detent pin assembly device is used to assemble a detent pin 911 and a ball 912 to form a detent pin assembly 917; the armature pin assembly device 220 is aligned with the detent pin assembly device 210 to assemble the detent pin assembly 917 and the armature 913 to form an armature pin assembly 918. The pole tube assembly device 300 is used to assemble the armature pin assembly 918, a pole cover 914, and a pole tube 915 to form a pole tube assembly 910. The phase converter assembly device 400 is used to assemble the pole tube assembly 910 and the coil assembly 920 to form a phase converter.

[0013] The assembly line 100 for phase adjusters in the embodiments of the present application is used for assembling phase adjusters 900, can increase the level of automation of the assembly of phase adjusters 900, improve production efficiency and ensure consistent product quality.

[0014] The structure and connection relationship of each device of assembly line 100 for phase adjusters according to the embodiment of the present application are described below.

[0015] The detent pin assembly device 210 is used to assemble a detent pin 911 and a ball 912 to form a detent pin assembly 917.

[0016] It is easy to understand that in the phase adjuster 900, after lifting the armature pin assembly 918, the ball 912 is a component that acts on the oil control valve.

[0017] The following is an example of the assembly of the locking pin assembly device 210.

[0018] With reference to Fig. 2 The indexing pin assembly device 210 comprises an indexing pin positioning platform 211, an indexing pin feeding mechanism 212, a ball feeding mechanism 213, and a ball pressing mechanism 214. The indexing pin feeding mechanism 212 is used to feed the indexing pin 911 (see Fig. 24) to feed the detent pin positioning platform 211. The ball feeding mechanism 213 is used to feed the ball 912 (see Fig. 24) to an upper end of the detent pin 911. The ball press mechanism 214 is used to rivet the upper end of the detent pin 911 and the ball 912.

[0019] With reference to the Fig. 2 and Fig. Figure 3 includes the indexing pin positioning platform 211, in particular a indexing pin assembly transfer manipulator 2111 and an indexing pin positioning device 2112, wherein the indexing pin positioning device 2112 is installed at one end of the indexing pin assembly transfer manipulator 2111. An indexing pin positioning section 2113 is provided on the indexing pin positioning device 2112. The indexing pin assembly transfer manipulator 2111 can drive the indexing pin positioning device 2112 such that it moves along a first stroke direction, so that the indexing pin positioning device 2112 moves between an indexing pin feed position, a ball feed position, and a ball press position.

[0020] In some embodiments of the present application, the indexing pin positioning device 2112 has an indexing pin feed position, a ball feed position, and a ball press position. During operation, the indexing pin positioning device 2112 first moves into the indexing pin feed position, wherein the indexing pin feed mechanism 212 feeds an indexing pin 911 to the indexing pin positioning platform 211; then the indexing pin positioning device 2112 moves into the ball feed position, wherein the ball feed mechanism 213 feeds a ball 912 to the upper end of the indexing pin 911; finally, the indexing pin positioning device 2112 moves into the ball press position, wherein the ball press mechanism 214 presses the ball 912 downwards to rivet the ball 912 and the upper end of the indexing pin 911 together, thus forming an indexing pin assembly 917.

[0021] It is easy to understand that the detent pin positioning device 2112 is designed to be movable, with the detent pin feeding mechanism 212, the ball feeding mechanism 213 and the ball pressing mechanism 214 being arranged spread out along a stroke of movement of the detent pin positioning device 2112, which not only promotes rational use of space, but also ensures accurate assembly of the detent pin 911 and the ball 912, thereby guaranteeing riveting accuracy.

[0022] In other embodiments, the locking pin 911 and the ball 912 can be supplied at the same position.

[0023] With reference to Fig. 2 The detent pin feeding mechanism 212 has a detent pin vibration discharge mechanism 2121 and a detent pin discharge tube 2122, wherein one end of the detent pin discharge tube 2122 is connected to the detent pin discharge opening of the detent pin vibration discharge mechanism 2121, and the other end is aligned with a detent pin positioning section 2113, wherein the detent pin discharge tube 2122 can guide the detent pin 911 to the detent pin positioning section 2113.

[0024] Optionally, the detent pin feeding mechanism 212 further includes a stop mechanism 2123, wherein the stop mechanism 2123 is an air cylinder that can be extended to block a discharge end of the detent pin discharge tube 2122, whereby only one detent pin 911 may fall onto the detent pin positioning section 2113 at a time.

[0025] With reference to Fig. Figure 4 shows that the ball feeding mechanism 213 comprises a ball storage chamber 2131 and a ball transfer manipulator 2134. The ball storage chamber 2131 is provided at its lower end with a ball discharge and lifting mechanism 2132 and at its upper end with a ball discharge opening 2133 for discharging the balls 912. The ball discharge and lifting mechanism 2132 can lift the balls 912 in the ball storage chamber 2131 so that one of the balls 912 exits the ball discharge opening 2133. A ball absorption section 2135 is provided at one end of the ball transfer manipulator 2134, which can adsorb the balls 912 at the ball discharge opening 2133. The ball transfer manipulator 2134 transfers the balls 912 from the ball discharge opening 2133 to the upper end of the detent pin 911, which is located in the detent pin positioning section 2113.

[0026] The ball feeding mechanism 213 is provided with a ball feeding opening 2136. The ball feeding opening 2136 assumes a widened shape, which facilitates feeding.

[0027] With reference to Fig. 2 The ball press mechanism 214 has a ball press drive mechanism 2141 and a ball press head (the ball press head in Fig. 2 is covered by a dust cover). The ball press drive mechanism 2141 can drive the ball press head downwards to act on the detent pin 911 and the ball 912, which are located on the detent pin positioning section 2113, and rivet the ball 912 into the upper end of the detent pin 911.

[0028] Preferably, the ball press head 2142 is concave inwards and fits the contour of the ball 912, so that the locking pin 911 surrounds the ball 912 and prevents the ball 912 from falling out of the upper end of the locking pin 911.

[0029] Optionally, the ball press mechanism 214 is further equipped with a detent rivet NG detection device for detecting an amount of downward pressing of the ball press head in order to determine whether the detent riveting is qualified.

[0030] With reference to Fig. 3 The detent pin assembly device 210 further comprises a detent pin in position detection mechanism 215, wherein the detent pin in position detection mechanism 215 is arranged on the detent pin positioning device 2112 to detect whether the detent pin 911 is in the detent pin positioning section 2113.

[0031] The detent pin in-position detection mechanism 215 is an example of an in-position sensor.

[0032] The following describes the working principle of the locking pin assembly device 210.

[0033] The indexing pin positioning device 2112 is located at an indexing pin feeding position, wherein the indexing pin feeding mechanism 212 feeds an indexing pin 911 to the indexing pin positioning section 2113. The indexing pin assembly transfer manipulator 2111 drives the indexing pin positioning device 2112 such that it moves forward into the ball feeding position, wherein the ball transfer manipulator 2134 adsorbs a ball 912 and feeds it to the upper end of the indexing pin 911.

[0034] The detent pin assembly transfer manipulator 2111 drives the detent pin positioning device 2112 to move forward into a ball pressing position, with the ball pressing mechanism 214 moving downwards and riveting the ball 912 and the bayonet 911 together to form a detent pin assembly 917.

[0035] The anchor pin assembly device 220 is aligned with the detent pin assembly device 210 to assemble the detent pin assembly 917 and the anchor 913, forming an anchor pin assembly 918.

[0036] The following is an example of the assembly of the locking pin assembly device 220.

[0037] With reference to Fig. 5 The anchor pin assembly device 220 comprises an anchor positioning platform 221, an anchor pin feeding mechanism 222, a pin pressing mechanism 223 and a first linear guide rail 225.

[0038] The anchor positioning platform 221 is a worktable for riveting the detent pin assembly 917 and the anchor 913. The anchor positioning platform 221 is installed at the output of the first linear guide rail 225, and the first linear guide rail 225 is used to drive the anchor positioning platform 221 so that it moves along a second stroke direction to form an anchor pin feeding position and a pin pressing position. When the anchor positioning platform 221 is in the anchor pin feeding position, the anchor pin feeding mechanism 222 is used to feed the anchor 913 to the anchor positioning platform 221 and then to feed the detent pin assembly 917 to the center hole of the anchor 913. When the anchor positioning platform 221 is in the pin pressing position, the pin pressing mechanism 223 is used to rivet the detent pin 911 of the detent pin assembly 917 and the anchor 913.

[0039] With reference to Fig. 6 The anchor positioning platform 221 is provided with an anchor positioning groove 2211, the center of which is provided with a concentric column 2212. It is easy to understand that when the anchor 913 is placed in the anchor positioning groove 2211, the concentric column 2212 is located in the center hole of the anchor 913 and can accommodate the detent pin assembly 917 inserted into the center hole of the anchor 913.

[0040] With reference to Fig. Figure 5 of the armature pin feeding mechanism 222 comprises an armature feeding manipulator 2221 and a detent pin assembly feeding manipulator 2222. The armature feeding manipulator 2221 feeds the armature 913 to the armature positioning groove 2211. The detent pin assembly feeding manipulator 2222 is aligned with the detent pin assembly device 210, takes the detent pin assembly 917 out of the detent pin positioning device 2112, and feeds it to the center hole of the armature 913.

[0041] Examples include the output end of the armature feed manipulator 2221 and the output end of the detent pin assembly feed manipulator 2222, which are typical pneumatic fingers.

[0042] With reference to the Fig. 5 and Fig. 7 The pin press mechanism 223 includes a pin press drive mechanism 2231, a pin press head (the pin press head in Fig. 7 is covered by a dust cover) and a pin-clamp finger 2232.

[0043] Driven by the first linear guide rail, the anchor positioning platform 221 is moved forward under the pin pressing mechanism 223, with the pin clamping finger 2232 clamping the detent pin 911, the pin pressing drive mechanism 2231 driving the pin pressing head to a downward movement to rivet the anchor 913 and the detent pin 911, forming an anchor pin assembly 918.

[0044] Preferably, the pin press head is hollow inside and its pressing surface is ring-shaped in order to press evenly and stably on the upper side of the detent pin 911.

[0045] This ensures that the upper surface of the 912 ball is not damaged during the riveting process.

[0046] Optionally, the pin press mechanism 223 is further equipped with an anchor pin rivet NG detection device for detecting an amount of downward pressing of the pin press head in order to determine whether the anchor pin riveting is qualified.

[0047] With reference to Fig. 6 further provides that the anchor pin assembly device 220 also has an anchor pin in position detection mechanism 224. The anchor pin in position detection mechanism 224 is arranged on the anchor positioning platform 221 to detect whether the assembly to be riveted is located in the anchor positioning groove 2211.

[0048] The anchor pin in-position detection mechanism 224 is an example of an in-position sensor.

[0049] The following describes the working principle of the anchor pin assembly device 220.

[0050] The armature feed manipulator 2221 feeds the armature 913 to the armature positioning groove 2211; The detent pin assembly feed manipulator 2222 takes the detent pin assembly 917 out of the detent pin positioning device 2112 and feeds it to the center hole of the armature 913; The first linear guide rail 225 drives the anchor positioning platform 221 so that it moves under the pin pressing mechanism 223; The pin clamping finger clamps the locking pin 911; The pin press head is pressed downwards to rivet the anchor 913 and the detent pin 911 to form the anchor pin assembly 918.

[0051] A pole tube assembly device 300 is used to assemble the anchor pin assembly 918, a pole cover 914 and a pole tube 915 to form a pole tube assembly 910;

[0052] The following is an example of the assembly of the polar tube assembly device 300.

[0053] With reference to Fig. 8 The polar tube assembly device 300 includes a rotary disk 310, an armature transfer manipulator 330, a pre-assembly mechanism 340 and a polar tube press fitting device 350.

[0054] With reference to Fig. 8 Several positioning devices 320 are evenly arranged along the circumferential direction of the turntable 310, each of the positioning devices 320 being installed on the turntable 310 for the armature 913, a pole cover 914 or a pole tube 915.

[0055] In some embodiments of the present application, eight positioning devices 320 are arranged.

[0056] Using the example of one of the positioning devices 320, with reference to Fig. 9 The positioning device 320 comprises a base plate 321, an armature positioning section 322, a pole cover positioning section 323, and a pole tube positioning section 324. The base plate 321 is detachably installed on the turntable 310, with the armature positioning section 322 and the pole tube positioning section each arranged on both sides of the pole cover positioning section 323.

[0057] The first position is the feed position. At the first position, the armature 913, the pole cover 914 and the pole tube 915 are fed to the positioning device 320.

[0058] For example, the first position is a first manual working position 390, in which an operator at the first manual working position 390 manually feeds the armature 913, the pole cover 914 and the pole tube 915 to a corresponding positioning section.

[0059] As a further example, the manipulator is used at the first position to feed the armature 913, the pole cover 914 and the pole tube 915 each to a corresponding positioning section on the positioning device 320.

[0060] With reference to Fig. 8 The pole tube assembly device 300 optionally includes a positioning device in-position detection mechanism 370, which is arranged above the feed position to detect whether the armature 913, the pole cover 914 and the pole tube 915 are in place.

[0061] An armature transfer manipulator 330 is used to transfer the armature 913 from the positioning device 320 to the armature pin assembly device 220.

[0062] It is easy to understand that, after the 913 has been fed through the first manual working position 390, the rotary table 310 together with the positioning device 320 is rotated into the feeding position of the armature transfer manipulator 330, whereby the armature transfer manipulator 330 grips the armature 913 and then transfers the armature 913 to the armature positioning platform 221 of the armature pin assembly device 220 as one of the raw materials for forming the armature pin assembly 918.

[0063] In some embodiments of the present application, the armature transfer manipulator 330 is the armature feed manipulator 2221, wherein the armature transfer manipulator 330 is defined in relation to the pole tube assembly device 300 and the armature feed manipulator 2221 is defined in relation to the armature pin assembly device 220.

[0064] A pre-assembly mechanism 340 is arranged downstream of the armature transfer manipulator 330 and is used to feed the armature pin assembly 918 formed by the armature pin assembly device 220 to the positioning device 320 and then to pre-assemble the pole tube 918, the pole cover 914 and the armature pin assembly 915 to form a pre-assembled pole tube assembly.

[0065] With reference to Fig. 8 In some embodiments of the present application, the pre-assembly mechanism 340 comprises a first manipulator 341 and a second manipulator 342. The first manipulator 341, the second manipulator 342, and the polar tube press fitting device 350 are arranged sequentially along one direction of rotation of the rotary disk 310, so that the entire polar tube assembly device 300 has a compact design.

[0066] The first manipulator 341 is used to remove the armature pin assembly 918 from the armature pin assembly device 220 and, after turning it over, assemble it with the pole cover 914 on the pole cover positioning section 323, so that a pole cover assembly is formed.

[0067] It is easy to understand that the anchor pin assembly 918 formed by the anchor pin assembly device 220 is in an upright state, while the upper end of the detent pin assembly 917 is inserted into the pole cover 914, whereby the anchor pin assembly 918 must be turned over and placed upside down and then assembled with the pole cover 914.

[0068] The second manipulator 342 is located downstream of the first manipulator 341. The second manipulator 342 is used to assemble a pole tube 915, located on the pole tube positioning section 324, with the pole cover assembly on the pole cover positioning section 323, thus forming a pre-assembled pole tube assembly.

[0069] The pole tube press fitting device 350 is located downstream of the second manipulator 342 and is used to remove and rivet the pre-assembled pole tube assembly located at the pole cover positioning section 323, thereby producing a pole tube assembly 910.

[0070] In some embodiments of the present application, the execution end of the first manipulator 341 and the execution end of the second manipulator 342 are conventional pneumatic fingers, wherein the execution end of the first manipulator 341 can clamp and turn the anchor pin assembly 918.

[0071] The specific design of one form of the polar tube press fitting device 350 is shown below as an example.

[0072] With reference to Fig. 10 The polar tube press fitting device 350 has a polar tube gripping mechanism 351, a positioning platform 352 for pre-assembled polar tube assembly and a polar tube press mechanism 353.

[0073] The positioning platform 352 for pre-assembled polar tube assemblies is used to position the pre-assembled polar tube assembly.

[0074] With reference to Fig. 10 and Fig. In some embodiments of the present application, the positioning platform 352 for pre-assembled polar tube assemblies comprises a worktable 3521 for riveting polar tubes and a positioning section 3522 for riveting polar tube assemblies, wherein the positioning section 3522 for riveting polar tube assemblies is installed on the worktable 3521 for riveting polar tubes and is used to position an inverted pre-assembled polar tube assembly.

[0075] The polar tube press mechanism 353 is used to rivet the pre-assembled polar tube assembly onto the positioning platform 352 for pre-assembled polar tube assemblies, forming a polar tube assembly 910.

[0076] With reference to Fig. 12 In some embodiments of the present application, the polar tube press mechanism 353 has a circumferential retaining finger 3531 for polar tube assemblies, wherein the circumferential retaining finger 3531 for polar tube assemblies engages the polar tube 915 of the pre-assembled polar tube assembly in the circumferential direction and presses downwards onto the polar tube 915, whereby the polar tube 915 of the pre-assembled polar tube assembly and the polar cover 914 are riveted together in one piece to form a polar tube assembly 910.

[0077] Optionally, the pole tube pressing mechanism 353 further includes a pole tube rivet NG detection device for detecting an amount of downward pressing of the circumferential retaining finger 3531 for pole tube assemblies to determine whether the pole tube riveting is qualified.

[0078] The polar tube gripping mechanism 351 is used to grip the pre-assembled polar tube assembly from the positioning device 320 and to place the pre-assembled polar tube assembly onto the positioning platform 352 for pre-assembled polar tube assemblies, and to remove the polar tube assembly 910 from the positioning platform 352 for pre-assembled polar tube assemblies and place it back into the positioning device 320.

[0079] With reference to Fig. 10 and Fig. 11 In some embodiments of the present application, the polar tube gripping mechanism 351 comprises a lifting and rotating mechanism 3511, a mounting frame 3512, and two gripping fingers. The mounting frame 3512 is connected to an output of the lifting and rotating mechanism 3511, the lifting and rotating mechanism 3511 being used to drive the mounting frame 3512 to raise or lower and rotate it, with a gripping finger being mounted at each end of the mounting frame 3512, the gripping finger being used to grip the pre-assembled polar tube assembly or the polar tube assembly 910.

[0080] As an example of the lifting and rotating mechanism 3511, the lifting and rotating mechanism 3511 comprises an L-shaped plate 3513, a rotary drive mechanism 3518, and a lifting drive mechanism 3519. A frame is provided with a vertical plate (not shown in the figure), wherein the lifting drive mechanism 3519 is installed on the vertical plate, the L-shaped plate 3513 is installed at the output of the lifting drive mechanism 3519, the rotary drive mechanism 3518 is installed on the lower side of the flat plate section of the L-shaped plate 3513, and a mounting frame 3512 is rotatably installed on the upper side of the flat plate section, with the output of the rotary drive mechanism 3518 being connected to the mounting frame 3512.

[0081] With reference to Fig. 10 The two gripping fingers have a first gripping finger 3514 and a second gripping finger 3515. The two gripping fingers have the same structure.

[0082] Using the example of the first gripping finger 3514, with reference to Fig. 11 The first gripping finger 3514 has a circumferential holding claw 3516 and a lower holding claw 3517. It is easy to understand that when transferring the pre-assembled polar tube assembly, the lower holding claw 3517 can receive the pre-assembled polar tube assembly and the circumferential holding claw encloses the polar tube 915 in the circumferential direction in order to jointly transfer the pre-assembled polar tube assembly.

[0083] Optionally, the polar tube press fitting device 350 also features a dust removal mechanism 354 for riveting polar tubes.

[0084] With reference to Fig. 12 the dust removal mechanism 354 for riveting polar tubes is arranged on the worktable 3521 for riveting polar tubes in order to clean the positioning section 3522 for riveting polar tube assemblies.

[0085] The dust removal mechanism 354 for riveting polar tubes is an example of a common suction and blowing dust removal mechanism.

[0086] With reference to Fig. 10 further provides that the polar tube press fitting device 350 also has a polar tube assembly in-position detection mechanism 355 to detect whether the polar tube assembly 910 is located in the positioning section 3522 for riveting polar tube assemblies. By way of example, the polar tube assembly in-position detection mechanism 355 is an in-position sensor.

[0087] The following describes the working principle of the polar tube press fitting device 350.

[0088] The first gripper finger 3514 is aligned with the positioning device 320; The first gripping finger 3514 grips the pre-assembled polar tube assembly; The lifting drive mechanism 3519 drives the L-shaped plate 3513 to lift, the L-shaped plate 3513 driving the first gripping finger 3514 to lift in order to grip the pre-assembled polar tube assembly; The rotary drive mechanism 3518 further drives the mounting frame 3512 to rotate, so that the first gripping finger 3514 is rotated to the positioning section 3522 for riveting polar tube assemblies; The lifting drive mechanism 3519 drives the L-shaped plate 3513 to lower, wherein the first gripping finger 3514 places the pre-assembled polar tube assembly onto the positioning section 3522 for riveting polar tube assemblies, after which the L-shaped plate is raised to reset; The rotary drive mechanism 3518 drives the mounting frame 3512 to rotate further, so that the first gripping finger 3514 bypasses the stroke of the polar tube press mechanism 353; The circumferential retaining finger 3531 for polar tube assemblies grips the pre-assembled polar tube assembly in the circumferential direction and presses it downwards, wherein the polar tube 915 of the pre-assembled polar tube assembly and the polar cover 914 are riveted together in one piece to form a polar tube assembly 910; The rotary drive mechanism 3518 drives the first gripping finger 3514 so that it rotates further towards the positioning device 320 to grip the next pre-assembled polar tube assembly, with the second gripping finger 3515 now reaching the positioning section 3522 for riveting polar tube assemblies to grip the riveted polar tube assembly 910; The rotary drive mechanism 3518 drives the first gripper finger 3514 so that it rotates further to the positioning section 3522 for riveting polar tube assemblies, whereby the second gripper finger 3515 now reaches the positioning device 320 in order to place the riveted polar tube assembly 910 back onto the positioning device 320.

[0089] It is easy to understand that with this arrangement the press fit of the pole tube can be carried out efficiently and the riveting efficiency can be improved.

[0090] With reference to Fig. 8 The polar tube assembly assembly device 300 optionally includes a dust removal device 360 ​​of the turntable, which is used to clean the positioning device 320 on the turntable 310.

[0091] The dust removal device 360 ​​of the turntable is, by way of example, a conventional suction and blowing dust removal mechanism. In further embodiments, the dust removal device 360 ​​of the turntable can also clean the positioning device 320 by means of a brush.

[0092] The following explains the working principle of the polar tube assembly device 300. The armature 913 is manually fed to the armature positioning section 322 of the positioning device 320, the pole cover 914 is manually fed to the pole cover positioning section 323, and the pole tube 915 is manually fed to the pole tube positioning section 324; The rotary disk 310 drives the positioning device 320 so that it moves to the armature transfer manipulator 330, the armature transfer manipulator 330 gripping the armature 913 and transferring the armature 913 to the armature pin assembly device 220; The rotary disk 310 drives the positioning device 320 so that it moves to the first manipulator 341, wherein the first manipulator 341 grasps the armature pin assembly 918 from the armature pin assembly device 220 and inserts the armature pin assembly 918 into the pole cover 914, so that a pole cover assembly is formed; The rotary disk 310 drives the positioning device 320 so that it moves to the second manipulator 342, the second manipulator 342 gripping the polar tube 915 and covering the polar tube 915 on the polar cover assembly, thus forming a pre-assembled polar tube assembly; The rotary disk 310 drives the positioning device 320 so that it moves to the pole tube press fitting device 350, the pole tube press fitting device 350 removing the pre-assembled pole tube assembly for riveting and transferring a qualifiedly riveted pole tube assembly 910 back to the pole cover positioning section 323 of the positioning device 320; The rotary disk 310 drives the positioning device 320 so that it rotates to the polar tube assembly discharge position 311, whereby the polar tube assembly 910 is removed by a third manipulator 380 described below and transferred to the next operation; The turntable 310 drives the positioning device 320 so that it rotates to the cleaning position, whereby the dust removal device 360 ​​of the turntable cleans the positioning device 320.

[0093] With reference to Fig. 1 The assembly line 100 for phase adjusters optionally includes a third manipulator 380 and a return feed line 500.

[0094] With reference to Fig. In the return conveying line 500, several return devices 510 are provided along its conveying direction, each return device 510 being equipped with a pole tube assembly positioning structure 511 and a coil assembly positioning structure 512. The pole tube assembly positioning structure 511 is used to position the pole tube assembly 910, and the coil assembly positioning structure 512 is used to position the coil assembly 920. The phase converter assembly device 400 is used to grip the pole tube assembly 910 and the coil assembly 920 from the return device 510 for assembly, forming a phase converter 900, which is then placed back onto the return device 510.

[0095] As an exemplary form of the feedback device 510, the pole tube assembly positioning structure is a pole tube assembly positioning groove, wherein the coil assembly positioning structure 512 is a coil assembly positioning groove.

[0096] With reference to Fig. In addition, the return feed line 500 is equipped with a second manual working position 530 and a third manual working position 540. The coil assembly 920 comprises a coil assembly body and a sealing ring. The operator completes the manual assembly of the coil assembly 920 at the second manual working position 530 and then feeds the coil assembly to the return device 510. At the third manual working position 540, a qualified phase converter 900 is removed.

[0097] With reference to Fig. 1 The third manipulator 380 is used to transfer the pole tube assembly 910 from the pole tube assembly assembly device 300 to the return device 510 on the return feed line 500.

[0098] With reference to Fig. In particular, the third manipulator 380 is aligned with the polar tube assembly discharge position 311 of the polar tube assembly assembly device 300. Pneumatic fingers of the output end of the third manipulator 380 can be reversed to position the polar tube assembly 910 upright on the return device 510.

[0099] In the description of the present application, "an upright arrangement" means that the polar tube 915 is located at the bottom and the polar cover 914 is located at the top. An "upside-down arrangement" of the polar tube assembly 910 means that the polar tube 915 is located at the top and the polar cover 914 is located at the bottom.

[0100] It is easy to understand that during the process of forming and riveting the pre-assembled polar tube assembly, the polar tube assembly 910 is inverted to facilitate its assembly. However, the polar tube assembly 910 is installed upright on the coil assembly 920; the third manipulator 380 reverses the polar tube assembly 910 when it is fed to the return device 510, so that it is placed upright on the return device 510, thus facilitating the assembly of the polar tube assembly 910 and the coil assembly 920.

[0101] The phase converter assembly device 400 is used to assemble the pole tube assembly 910 and the coil assembly 920 to form a phase converter 900.

[0102] With reference to the Fig. 14 and Fig. 15 The specific construction of an exemplary phase converter assembly device 400 is described below.

[0103] With reference to Fig. 14 The phase converter assembly device 400 comprises a pole tube coil positioning clamp 410, a feed and discharge manipulator 420, a coil riveting mechanism 430 and a rotary table 440.

[0104] In some embodiments of the present application, the pole tube coil positioning clamp 410 is attached to the rotary table 440, wherein the pole tube coil positioning clamp 410 can rotate together with the rotary table 440 to achieve a feed and discharge position, and a riveting position.

[0105] The rotary table 440 is driven by a "gear and rack" mechanism, causing it to rotate.

[0106] When the pole tube coil positioning clamp 410 is in the feed and discharge position, the pole tube coil positioning clamp 410 corresponds to the feed and discharge manipulator 420. When the pole tube coil positioning clamp 410 is in the riveting position, the pole tube coil positioning clamp 410 corresponds to the coil riveting mechanism 430.

[0107] The pole tube coil positioning clamp 410 has a pole tube assembly positioning device 411 and a coil assembly lifting mechanism 412.

[0108] With reference to Fig. 15 in particular the pole tube assembly positioning device 411 has a pole tube assembly positioning section 4111 and a counter-punch 4112, wherein a coil assembly positioning block 4121 is provided at the output of the coil assembly lifting mechanism 412, wherein the coil assembly positioning block 4121 is located below the counter-punch 4112.

[0109] The feed and discharge manipulator 420 is used to feed the pole tube assembly 910 to the pole tube assembly positioning section 4111, to feed the coil assembly 920 to the coil assembly positioning block 4121, and then to discharge the phase converter 900 formed by riveting from the coil assembly positioning block 4121.

[0110] With reference to Fig. Figure 14 shows that the feed and discharge manipulator 420 includes, by way of example, a feed and discharge manipulator 421 for coil assemblies and a pole tube assembly feed manipulator 422. The feed and discharge manipulator 421 for coil assemblies is used to transfer the coil assembly 920 or the phase converter 900. The pole tube assembly feed manipulator 422 is used to transfer the pole tube assembly 910.

[0111] With reference to Fig. 15 The coil riveting mechanism 430 includes a coil pole tube press head 431 and a pole tube assembly transfer manipulator 432.

[0112] The pole tube assembly transfer manipulator 432 is used to grip the pole tube assembly 910 from the pole tube assembly positioning section 4111 and place it into the counter-punch 4112, with the coil pole tube press head 431 being guided through the counter-punch 4112 to rivet the pole tube assembly 910 and the coil assembly 920 together, so that the phase converter 900 is formed.

[0113] It is further provided that the number of pole tube coil positioning clamps 410 is two, namely a first pole tube coil positioning clamp 450 and a second pole tube coil positioning clamp 460, wherein the first pole tube coil positioning clamp 450 and the second pole tube coil positioning clamp 460 are each installed at both ends of the rotary table 440. That is, the number of pole tube assembly positioning devices 411 and coil assembly lifting mechanisms 412 is each two, wherein the coil assembly lifting mechanism 412 corresponds one-to-one to the pole tube assembly positioning device 411. When one group consisting of a pole tube assembly positioning device 411 and a coil assembly lifting mechanism 412 is in the feed and discharge position, the other group consisting of a pole tube assembly positioning device 411 and a coil assembly lifting mechanism 412 is in the riveting position.It is easy to understand that with this arrangement the press fit of the pole tube assembly 910 and the coil assembly 920 can be carried out efficiently and the riveting efficiency can be improved.

[0114] The following describes the working principle of the phase converter assembly device 400.

[0115] The first pole tube coil positioning clamp 450 is located at the feed and discharge position, while the second pole tube coil positioning clamp 460 is located at the rivet position; The feed and discharge manipulator 421 for coil assemblies feeds the coil assembly 920 to the coil assembly positioning block 4121 of the first pole tube coil positioning terminals 450; The pole tube assembly feed manipulator 422 takes the pole tube assembly 910 out of the return device 510 and feeds it to the pole tube assembly positioning section 4111 of the first pole tube coil positioning terminals 450; The rotary table 440 rotates and drives the first pole tube coil positioning clamp 450 so that it rotates into the riveting position, while at the same time the second pole tube coil positioning clamp 460 rotates into the feed and discharge position; The coil assembly lifting mechanism 412 of the first pole tube coil positioning clamp 450 drives the coil assembly positioning block 4121 to lift, so that the coil assembly 920 is on the coil assembly positioning block 4121 close to the lower side of the counter-punch 4112; The pole tube assembly transfer manipulator 432 takes out the pole tube assembly 910, which is located on the pole tube assembly positioning section 4111, and transfers it to a position above the punch hole 4112, and places the pole tube assembly 910 through the counter punch 4112 onto the coil assembly 920; The coil-pole tube press head 431 moves downwards to rivet the pole tube assembly 910 and the coil assembly 920 together, forming a phase converter 900; The pole tube assembly feed manipulator 422 guides the phase adjuster 900 back to the return device 510.

[0116] The phase converter assembly device 400 rivets the pole tube assembly 910 and the coil assembly 920 together to form the phase converter 900.

[0117] With reference to Fig. The assembly line 100 for phase adjusters, located upstream of the phase adjuster assembly device 400 along the conveying direction of the return conveying line 500, further includes an O-ring assembly device 600. The O-ring assembly device 600 is arranged along the conveying direction of the return conveying line 500 between the third manipulator 380 and the phase adjuster assembly device 400. The O-ring assembly device 600 is used to clamp an O-ring 916 onto the pole tube 915 and the pole cover 914 of the pole tube assembly 910 to improve sealing performance.

[0118] The following is an example of the construction of the O-ring assembly device 600.

[0119] With reference to Fig. Figure 16 of the O-ring assembly device 600 comprises an O-ring feeder assembly 610, an O-ring assembly assembly 620, and an O-ring transfer manipulator 630. The O-ring feeder assembly 610 is provided with an O-ring discharge position 611 and can dispense an O-ring 916 precisely to the O-ring discharge position 611. The O-ring assembly assembly 620 is used to clamp the O-ring 916 onto the polar tube assembly 910 to form a sealed polar tube assembly 910.

[0120] In some embodiments of the present application, the O-ring feeder assembly 610 uses a “vibrating disc + linear feeder” form for discharge.

[0121] With reference to Fig. 17 and Fig. 18 The O-ring assembly 620 has a liftable O-ring assembly table, the upper end face of which is an O-ring assembly table surface 621. The O-ring assembly 620 further comprises an expanding claw 622, an expanding claw lifting mechanism 623, a retraction ring 624, a release and lifting mechanism 625, and a grooved slide 626. The expanding claw lifting mechanism 623, the release and lifting mechanism 625, and the grooved slide 626 are installed on the O-ring assembly table, with one end of the expanding claw 622 projecting from the O-ring assembly table surface 621 to form an O-ring placement section 6223.

[0122] The O-ring transfer manipulator 630 is used to adsorb the O-ring 916 from an O-ring discharge position 611 and place it on an O-ring feed position.

[0123] The spreading claw 622 is laterally slidable on the slide 626 with grooves, wherein the spreading claw 622 has a spread state and a retracted state.

[0124] With reference to Fig. 19 In particular, the spreading claw 622 is provided with several claw plates 6224.

[0125] With reference to Fig. Section 18 of the slide 626 has several lateral sliding grooves 6261. The lateral sliding grooves 6261 correspond one-to-one with the claw plates 6224, the claw plates 6224 being slidably arranged in the lateral sliding grooves 6261.

[0126] With reference to Fig. 19 The retraction ring 624 is mounted on the outside of the spreader claw 622, the upper end of the spreader claw lifting mechanism 623 being provided with a lifting block having a first circumferential surface 6231. Accordingly, a second circumferential surface 6221 is provided on the lower inner side of the spreader claw 622. When the spreader claw lifting mechanism 623 pushes the spreader claw 622 upwards, the first circumferential surface 6231 and the second circumferential surface 6221 bear against each other to cause the spreader claw 622 to slide laterally, thereby stretching the O-ring 916. The inner wall of the retraction ring 624 is provided with a third circumferential surface 6241. Accordingly, the outside of the spreader claw 622 is provided with a fourth circumferential surface 6222.When the unlocking and lifting mechanism 625 pushes the retraction ring 624 upwards, the third circumferential surface 6241 and the fourth circumferential surface 6222 come into contact with each other to retract the spreading claw 622 into the grooved slide 626, thereby removing the O-ring 916.

[0127] With reference to Fig. 16 The O-ring assembly 620 optionally also includes an O-ring in-position detection sensor 627 for detecting whether the O-ring 916 on the pole tube assembly 910 is qualifiedly stretched.

[0128] The following describes the working principle of the O-ring assembly device 600.

[0129] The O-ring feeder assembly 610 feeds the O-ring 916 to the O-ring discharge position 611; The O-ring assembly table is raised to a preset height; The O-ring transfer manipulator 630 transfers the O-ring 916 from an O-ring discharge position 611 to the upper end of the spreading claw 622; The spreading claw lifting mechanism 623 pushes the spreading claw 622 upwards, so that the spreading claw 622 is in a spread state; An external manipulator removes the polar tube assembly 910 from the return device 510 and, after turning it over, inserts it into a central area of ​​the spreading claw 622; The unlocking and lifting mechanism 625 pushes the retraction ring 624 upwards, so that the spreading claw 622 is in a retracted state; The O-ring 916 is automatically installed on the polar tube assembly 910 to form a sealed polar tube assembly 910; The external manipulator guides the sealed polar tube assembly 910 back to the return device 510.

[0130] Furthermore, it is planned that the assembly line 100 for phase adjusters will also have some devices for functional testing or marking of product information in order to ensure the product quality and traceability of the finally discharged phase adjuster 900.

[0131] With reference to Fig. In some embodiments of the present application, it is provided that the assembly line 100 for phase adjusters further comprises a function detection device 700, wherein the function detection device 700 is arranged along the conveying direction of the return conveying line 500 downstream of the phase adjuster assembly device 400 and is used to detect whether the performance of the phase adjuster 900 conforms to the standard.

[0132] With reference to Fig. 1 In some embodiments of the present application, four function detection devices 700 are provided, wherein the four function detection devices 700 have the same structure and are arranged sequentially along the conveying direction of the return conveying line 500 downstream of the phase converter assembly device 400 in order to improve the efficiency of detecting the functionality of the phase converter 900.

[0133] Using one of the function acquisition devices 700 as an example, an exemplary setup of the function acquisition device 700 is shown.

[0134] With reference to Fig. 20 In some embodiments of the present application, the function detection device 700 comprises a phase-changer positioning table 710, a phase-changer detection mechanism 720, a probe clamp 730 and a fourth manipulator 740.

[0135] The phase adjuster positioning table 710 is used to position the phase adjuster 900 and includes a phase adjuster lifting mechanism 711 and a positioning ring 712. A phase adjuster placement position 7111 is provided at the upper end of the phase adjuster lifting mechanism 711, and the phase adjuster lifting mechanism 711 can drive the phase adjuster placement position 7111 to raise or lower it. The fourth manipulator 740 is used to remove the phase adjuster 900 from the return device 510 and place it at the phase adjuster placement position 7111. The positioning ring 712 is arranged above the phase adjuster placement position 7111. After the phase adjuster placement position 7111 has risen, the phase adjuster 900 is engaged in the positioning ring 712.

[0136] The phase adjuster detection mechanism 720 is used to detect a thrust value of the phase adjuster 900.

[0137] The phase-changer detection mechanism 720 comprises a thrust lever 721, a thrust sensor 722, and a probe 723. The thrust lever 721 is mounted on the frame of the phase-changer positioning table 710 by means of a screw pin and has a first end 7211 and a second end 7212. The first end 7211 is located above the positioning ring 712 and is used to transmit the thrust force of the phase-changer 900. The thrust sensor 722 is mounted on the frame of the phase-changer positioning table 710, with the second end 7212 located above the thrust sensor 722. It is used to transmit the thrust force of the phase-changer 900 by lever action and to act upon the thrust sensor 722. The probe 723 is used to be inserted into an interface 940 of the phase-changer 900.

[0138] In the description of the present application, the other end of probe 723 is connected to the battery. Probe 723 is used only as a conductive part. When the battery is powered, the coil assembly 920 is energized and generates a magnetic field to push the armature pin assembly 918 outwards.

[0139] The probe clamp 730 can adjust the angle of the probe 723 in the phase adjuster detection mechanism 720 and insert the probe 723 into the interface 940 of the phase adjuster 900.

[0140] With reference to Fig. 21 The probe clamp 730 has an angle adjustment plate 731 and a probe mounting part 732, wherein the probe mounting part 732 is installed on the angle adjustment plate 731 such that its angle is adjustable, wherein the probe 723 and a battery mounting position are mounted on the probe mounting part 732.

[0141] For example, the angle adjustment plate 731 is provided with several arc grooves 7311, wherein the probe mounting part 732 is installed on one side of the angle adjustment plate 731, a threaded element being guided through the arc groove 7311 and interacting with a nut to install the probe mounting part 732 on the angle adjustment plate 731. If the installation angle of the probe 723 needs to be adjusted, the probe mounting part 732 is slid along the arc groove 7311 and then secured to adjust the probe 723 to a suitable angle.
