The "connection" and "coupling" mentioned in this application, under reasonable circumstances (not constituting a self-contradiction), include direct and indirect connections (couplings).

[0040] A type of assembled plastic part 6000 assembled using the assembled plastic part 6000 assembly system of the present invention is as follows: Figure 1As shown, the combined plastic part 6000 includes a housing 6100, a terminal holding auxiliary structure 6300 (TPA), a cap 6700 (CAP), a handle 6800, a slide 1 6400, a slide 2 6500, a sealing ring 6200 and a sealing gasket 6600. The housing 6100 is roughly a rectangular parallelepiped, and the housing 6100 is provided with three cavities along its width direction; the cap 6700 (CAP) and the sealing gasket 6600 are installed into the middle cavity of the housing 6100 from top to bottom; the terminal holding auxiliary structure 6300 (TPA) and the sealing ring 6200 are installed into the middle cavity of the housing 6100 from bottom to top; the slide 1 6400 and the slide 2 6500 are installed into the middle cavity of the housing 6100 from bottom to top; Figure 1 The handles 6800 are inserted into the cavities on both sides of the shell 6100 from top to bottom and cooperate with the slide 1 6400 and the slide 2 6500 respectively.

[0041] like Figure 2 As shown, the assembly system of the combined plastic part 6000 of this embodiment includes an apparatus 1000, an apparatus 2000, an apparatus 3000 and an apparatus 4000 connected in sequence by a conveying device 7000; the apparatus 1000, the apparatus 2000, the apparatus 3000 and the apparatus 4000 all include a turntable and a plurality of shell carriers arranged along the circumference of the turntable; the shell carrier is used to position the shell 6100; the apparatus 1000 also includes an assembly device 1300 for installing the sealing ring 6200 into the shell 6100; the apparatus 2000 also includes an assembly device 2300 for installing the terminal holding auxiliary structure 6300 into the shell 6100, an assembly device 2300 for installing the slide 1 6400 into the slide 1 The assembly device three 2400 of the shell 6100 and the assembly device four 2500 for installing the slide two 6500 into the shell 6100, the assembly device two 2300, the assembly device three 2400 and the assembly device four 2500 are distributed along the circumference of the turntable of the device two 2000; the device three 3000 also includes the assembly device five 3300 for installing the sealing gasket 6600 into the shell 6100 and the assembly device six 3400 for installing the cap 6700 into the shell 6100, the assembly device five 3300 and the assembly device six 3400 are distributed along the circumference of the turntable of the device three 3000; the device four 4000 also includes the assembly device seven 4300 for installing the handle 6800 into the shell 6100.

[0042] The turntable can adopt a cam divider, a DD motor or a servo motor 433124, etc., and the present invention does not limit it, as long as it can drive the housing carrier to rotate. In this embodiment, the turntable includes a DD motor and an annular disc body installed at the output end of the DD motor, and the housing carrier is fixed to the corresponding annular disc body.

[0043] In order to make it easier to assemble the sealing ring 6200 and the terminal retaining auxiliary structure 6300, the shell 6100 can be flipped between the device 2000 and the device 3000. For example, a part of the conveying device 7000 can be set to rotate, or a robot can be set to flip the shell 6100 sent out by the device 2000 180 degrees and then place it on the conveying device 7000; a robot can also be set before entering the device 3000 to flip the shell 6100 180 degrees and then place it into the shell carrier 3 3200 of the device 3000; it is obvious that there are many structures for realizing the 180-degree flipping of the shell 6100, which are not listed one by one here, and the above-listed flipping methods should not be understood as limitations on the present invention. By flipping the shell 6100 180 degrees, the sealing ring 6200 and the terminal retaining auxiliary structure 6300 are assembled from top to bottom in both device 1000 and device 2000, and then the shell 6100 is flipped 180 degrees again, and the sealing gasket 6600, the cap 6700 and the handle 6800 are assembled from top to bottom in device 3000 and device 4000.

[0044] The conveying device 7000 can be a belt conveyor, a single-axis robot, a direct vibration feeder, etc. The present invention does not limit it, as long as it can transfer the shell 6100 between various devices.

[0045] The housing carrier may have a contoured groove adapted to the outer contour of the housing 6100, so as to position the housing 6100. In some embodiments, the housing carrier may be configured as a plurality of positioning blocks, which are distributed in a rectangular shape, and the rectangle is adapted to the outer contour of the housing carrier, and the positioning blocks of two adjacent sides of one group of the rectangle are set to be elastically retractable, for example, the positioning blocks are set to be fixed blocks and retractable blocks, and a compression spring is set between the fixed blocks and the retractable blocks, so that the positioning blocks of the other two adjacent sides are the positioning reference, and the elastically retractable positioning blocks clamp the housing 6100.

[0046] The turntables of the device 1000, the device 2000, the device 3000 and the device 4000 are respectively the turntable 1100, the turntable 2100, the turntable 3100 and the turntable 4100, and the shell carriers of the device 1000, the device 2000, the device 3000 and the device 4000 are respectively the shell carrier 1200, the shell carrier 2200, the shell carrier 33200 and the shell carrier 44200. The working principle of the assembly system of the combined plastic part 6000 of this embodiment is:

[0047] The shell 6100 is placed on the shell carrier 1200, and the turntable 1100 drives the shell carrier 1200 equipped with the shell 6100 to rotate to the assembly device 1300. The assembly device 1300 installs the sealing ring 6200 on the shell 6100, and the turntable 1100 continues to drive the shell carrier 1200 equipped with the shell 6100 to rotate out of the assembly device 1300; the conveying device 7000 delivers the shell 6100 equipped with the sealing ring 6200 to The housing carrier 2200 of the second device 2000 and the second turntable 2100 carry the housing carrier 2200 with the housing 6100 to the second assembly device 2300, the third assembly device 2400 and the fourth assembly device 2500 respectively. The second assembly device 2300, the third assembly device 2400 and the fourth assembly device 2500 respectively install the terminal holding auxiliary structure 6300, the first slide 6400 and the second slide 6500 to the housing 6100, and the turntable 1100 The shell carrier 2200 with the shell 6100 is driven out; the shell 6100 is delivered to the shell carrier 3200 of the equipment 3000 by the conveying device 7000, and the turntable 3100 takes the shell carrier 3200 with the shell 6100 to the assembly device 5 3300 and the assembly device 6 3400 respectively, and the assembly device 5 3300 and the assembly device 6 3400 respectively install the sealing gasket 6600 and the cap 6700 to the shell 6100 0, turntable three 3100 continues to rotate out with shell carrier three 3200 equipped with shell 6100, and the conveying device 7000 delivers the shell 6100 to shell carrier four 4200 of equipment four 4000, turntable four 4100 rotates shell carrier four 4200 equipped with shell 6100 to assembly device seven 4300, and assembly device seven 4300 installs handle 6800 into shell 6100; this reciprocating cycle completes the assembly of all combined plastic parts 6000.

[0048] like Figure 2 As shown, device 1 1000, device 2 2000, device 3 3000 and device 4 4000 are all equipped with feeding devices. Specifically, device 1 1000 is respectively connected with housing feeding device 1400 and sealing ring feeding device 1500; device 2 2000 is connected with terminal holding auxiliary structure feeding device 2600, slide 1 feeding device 2700 and slide 2 feeding device 2800; device 3 3000 is connected with sealing gasket feeding device 3500 and cap feeding device 3600; device 4 4000 is connected with handle feeding device 4400; the feeding device can adopt a vibrating feeder or the like. In some embodiments, such as Figure 2 As shown, device 1 1000, device 2 2000, device 3 3000 and device 4 4000 are distributed in a rectangular shape. Compared with other arrangements, the rectangular distribution can shorten the walking distance of operators between the devices, reduce the labor intensity of operators, and reduce the time for replenishing materials to the feeding equipment.

[0049] For different specifications of assembled plastic parts 6000, the number of holes of cap 6700 is different. If a punching device is configured separately for each specification of assembled plastic part 6000, the diameter of the annular disk of device 3000 will be increased. In addition, since the punching devices cannot overlap, only the sealing gasket 6600 of one specification of assembled plastic part 6000 is assembled at the same time as the punching, while the sealing gasket 6600 and cap 6700 of other specifications of assembled plastic parts 6000 are not synchronized, and there is a waiting time, which slows down the production cycle. Therefore, in some embodiments, such as Figure 2 As shown, device five 5000 for punching the cap 6700 is arranged between device three 3000 and the cap feeding device 3600; in this way, the punching is completed by device five 5000 alone, and device three 3000 is only responsible for the assembly of the sealing gasket 6600 and the cap 6700. The sealing gasket 6600 and the cap 6700 of the combined plastic parts 6000 of different specifications are assembled simultaneously in device three 3000, and the production efficiency is higher.

[0050] like Figure 3 As shown, in some embodiments, the apparatus 5000 may include a punching device 5100 and a transfer device 5200 for transferring the punched cap 6700 to the apparatus 3000; the punching device 5100 includes a punching die 5110, a press 5120 for driving the punching die 5110 to punch, and a cap carrier 5130 for positioning the cap 6700; Figure 4 As shown, the punch die 5110 includes a body 5111, a punch 5112, a reset device 5113 and a limit device 5114; the body 5111 has a limit structure 51111; the punch 5112 and the limit device 5114 are provided in multiple and one-to-one correspondence, and the punch 5112 is configured to slide within the range limited by the limit structure 51111 and the reset device 5113; the reset device 5113 has a first telescopic portion 51133, when the punch 5112 is in the initial position mode, the first telescopic portion 51133 extends along the movement direction of the die 5110 and is used to reset the punch 5112; the limiting device 5114 has a second telescopic portion 51143, and when the punch 5112 corresponding to the limiting device 5114 is in the punching mode, the second telescopic portion 51143 extends along the direction perpendicular to the movement direction of the die 5110 and is used to fix a part of the punch 5112 between the second telescopic portion 51143 and the limiting structure 51111.

[0051] It can be understood that the number of punches 5112 covers the number of holes of the cap 6700 of the assembled plastic part 6000 of all specifications; when punching, the second telescopic part 51143 of the limit device 5114 corresponding to the number of holes of the cap 6700 extends to fix the corresponding punch 5112, and then the press 5120 drives the die 5110 to move toward the cap 6700, and the fixed punch 5112 flushes out the connected material in the hole of the cap 6700, while the other punches 5112 are not fixed, so after contacting the cap 6700, the punch 5112 retreats, and after punching is completed, the press 5120 drives the die 5110 back. When replacing the cap 6700 of another specification, the first telescopic part 51133 of the reset device 5113 extends to reset the punch 5112, and then the second telescopic part 51143 of the limit device 5114 corresponding to the specification is extended to fix the corresponding punch 5112.

[0052] The transfer device 5200 may be a single-axis robot, a synchronous belt conveyor, etc., and the present invention does not limit it, as long as it can achieve the position change of the cap 6700. In some embodiments, such as Figure 3 As shown, the transfer device 5200 may include a cap turntable 5210 and a robot 1 5220 for transferring the cap 6700 from the cap turntable 5210 to the device 3 3000, and a plurality of cap carriers 5130 are arranged along the circumference of the cap turntable 5210 and fixed to the cap turntable 5210. The cap turntable 5210 may have the same structure as the above-mentioned turntable 1 100, turntable 2 2100, turntable 3 3100 or turntable 4 4100, or may adopt other forms. Considering that the hole spacing of the cap 6700 is small, one punching device 5100 covering all specifications of the assembled plastic parts 6000 may cause the second telescopic portion 51143 of the limiting device 5114 to be too small, thereby reducing the strength and increasing the frequency of replacement. Therefore, in some embodiments, at least two punching devices 5100 are arranged along the cap turntable 5210, so that the punches 5112 and the limiting devices 5114 can be flexibly arranged to increase the strength and reduce the frequency of replacing the limiting devices 5114. For example, for the caps 6700 with small spacing, the punches 5112 of the punching device 5100 are arranged at intervals. For the convenience of explanation, as shown in FIG. Figure 5As shown, assuming that the holes of the cap 6700 from one end to the other are respectively the first hole 6701, the second hole 6702, the third hole 6703, the fourth hole 6704, the fifth hole 6705, the sixth hole 6706, the seventh hole 6707 and the eighth hole 6708, taking two punching devices 5100 as an example, the punch 5112 of one punching device 5100 corresponds to the first hole 6701, the third hole 6703, the fifth hole 6705 and the seventh hole 6707, and the punch 5112 of the other punching device 5100 corresponds to the second hole 6702, the fourth hole 6704, the sixth hole 6706 and the eighth hole 6708, thereby increasing the distance between the punches 5112 and indirectly increasing the distance between the limit devices 5114, so that the size of the second telescopic portion 51143 can be made larger to improve the strength.

[0053] In some embodiments, Figure 6 As shown, the main body 5111 has a stepped through hole 51112 , the punch 5112 is a stepped shaft slidably matched with the stepped through hole 51112 , and the stepped surface of the stepped through hole 51112 is a limiting structure 51111 .

[0054] In some embodiments, Figure 6 As shown, the reset device 5113 includes a plurality of ejector pins 51131 corresponding to the plurality of punches 5112 one by one and a reset drive unit 51132 driving the plurality of ejector pins 51131 to extend and retract along the moving direction of the die 5110. The ejector pins 51131 are the first retractable part 51133. The reset drive unit 51132 can be a drive device such as a cylinder, a crank slider mechanism, etc., which drives the load to perform linear motion. In some embodiments, such as Figure 6 As shown, the reset drive unit 51132 is a telescopic cylinder 51134. The cylinder body of the telescopic cylinder 51134 is fixed to the output end of the press 5120, and the piston rod of the telescopic cylinder 51134 is connected to a plurality of ejector pins 51131.

[0055] In some embodiments, Figure 6As shown, a stripper plate 5115 is provided between the body 5111 and the cap carrier 5130, the stripper plate 5115 is connected to the body 5111, and a stripper spring 5116 is provided between the stripper plate 5115 and the body 5111, and the stripper plate 5115 is slidably matched with the punch 5112. The stripper plate 5115 can be connected to the body 5111 by equal height screws. By setting the unloading spring 5116 and the unloading plate 5115, when the press machine 5120 drives the die 5110 to move toward the cap 6700, the unloading plate 5115 first contacts the cap 6700 and presses the cap 6700 through the unloading spring 5116, on the one hand, to prevent the cap 6700 from moving during the punching process, and on the other hand, to guide the punch 5112; and when the punch 5112 returns, the unloading plate 5115 continues to press the cap 6700 under the action of the unloading spring 5116 to prevent the punch 5112 from lifting the cap 6700.

[0056] In some embodiments, Figure 6 As shown, the limiting device 5114 includes a telescopic rod 51141 and a limiting driving unit 51142 that drives the telescopic rod 51141 to extend and retract in a direction perpendicular to the moving direction of the punch 5110. The telescopic rod 51141 is a second telescopic portion 51143. The limiting driving unit 51142 can be a driving device that drives the load to perform linear motion, such as a cylinder, a crank slider mechanism, etc. In some embodiments, Figure 6 As shown, the limit drive unit 51142 includes a second telescopic cylinder 511421 and a reset spring 511422. The telescopic rod 51141 is in the shape of a stepped shaft. The body 5111 has a stepped hole adapted to the telescopic rod 51141. The reset spring 511422 is a compression spring, and its two ends respectively abut against the step surface of the telescopic rod 51141 and the step surface of the stepped hole. The cylinder body of the second telescopic cylinder 511421 is fixed to the body 5111. The piston rod of the second telescopic cylinder 511421 abuts against the end of the telescopic rod 51141, that is, the telescopic rod 51141 is extended by the telescopic cylinder, and the telescopic rod 51141 is retracted by the reset spring 511422. In some embodiments, as Figure 6 As shown, the main body 5111 includes a mounting block 1 51113 and a mounting block 2 51114. The mounting block 1 51113 and the mounting block 2 51114 are detachably connected. When the telescopic rod 51141 needs to be replaced, it is only necessary to remove the mounting block 1 51113. There are fewer disassembly parts, and replacement is more convenient and quick.

[0057] In some embodiments, Figure 7 and Figure 8 As shown, the assembly device 7 4300 may include a clamping device 4310 for clamping the handle 6800, a manipulator 2 4320 for driving the clamping device 4310 to move so as to insert the clamped handle 6800 into the housing 6100, and a support structure 4330 for supporting the housing 6100; Figure 8 , Fig. 9 and Fig.10 As shown, the expansion structure 4330 includes an expansion component 4331 and a lifting drive component 4332, and the expansion component 4331 includes two relatively arranged expansion fingers 43311 and a finger driving component 43312 for driving the expansion fingers 43311 to open and close; when the assembly device seven 4300 is in the assembly mode, the lifting drive component 4332 is used to drive the expansion structure 4330 to move, so that the two expansion fingers 43311 are inserted into the gap of the mounting handle 6800 of the shell 6100, and the finger driving component 43312 is used to drive the two expansion fingers 43311 to open, so as to expand the gap of the mounting handle 6800 of the shell 6100, and the manipulator two 4320 is used to drive the handle 6800 on the clamping device 4310 to be inserted into the shell 6100. When turntable four 4100 rotates the shell 6100 to assembly device seven 4300, the lifting drive component 4332 drives the two spreading fingers 43311 to move toward the shell 6100 and insert them into the cavities on both sides of the shell 6100 respectively, and the cavities on both sides are the gaps in the shell 6100 for installing the handle 6800; then the finger driving component 43312 drives the two spreading fingers 43311 to open, and expand the cavities on both sides, and the manipulator two 4320 inserts the handle 6800 into the shell 6100, and then the two spreading fingers 43311 are reset, and the cavities on both sides are restored, and the protrusions on both sides of the vertical arm of the handle 6800 are respectively inserted into the holes in the cavity wall of the shell 6100 and the corresponding grooves of the slide, and the lifting drive component 4332 drives the two spreading fingers 43311 to leave the cavities on both sides to complete the assembly of the handle 6800. Since the handle 6800 is a thin sheet structure, and the line connecting the clamping point and the protruding point of the handle 6800 and the direction of inserting the handle 6800 into the shell 6100 have a clamp, if the handle 6800 is directly inserted into the shell 6100 by the second manipulator 4320, the handle 6800 is subjected to a force couple, and the assembly may not be completed and the handle 6800 and the shell 6100 may be damaged. Therefore, the present invention is provided with a propping component 4331 to prop open the cavities on both sides of the shell 6100 to prevent the handle 6800 from being subjected to the reaction force of the shell 6100 when the handle 6800 is inserted.

[0058] In some embodiments, Fig. 9 and Fig.10As shown, the finger driving component 43312 includes a base 433121, a rotating shaft 433122 rotatably supported on the base 433121, two end cams 433123 fixed to the rotating shaft 433122, a motor 433124 driving the rotating shaft 433122 to rotate, a moving seat 433125 fixed to the output end of the lifting driving component 4332, and two cam follower components 433126 respectively connected to the two end cams 433123; the two cam follower components 433126 are slidably connected to the base 433121 in a direction parallel to the rotating shaft 433122. 121, two driven rollers 1 are arranged at one end of each cam follower component 433126, and driven roller 2 4331262 is arranged at the other end; the outer circumferential surfaces of the two driven rollers 1 4331261 are tangent to the two end surfaces of the end cam 433123 respectively; the two spreading fingers 43311 are slidably connected to the moving seat 433125 along the spreading direction thereof, the spreading fingers 43311 have a slide groove 433111 along the lifting direction of the spreading structure 4330, and the driven roller 2 4331262 is located in the slide groove 433111 and is adapted to the slide groove 433111. In some embodiments, the lifting drive component 4332 is a telescopic cylinder 3 43321, the cylinder body of the telescopic cylinder 3 43321 is fixed to the base 433121, and the piston rod of the telescopic cylinder 3 43321 is connected to the lifting seat. The motor 433124 drives the two end face cams 433123 to rotate through the rotating shaft 433122, thereby driving the two cam follower parts 433126 to drive the two spreading fingers 43311 to open and close. The timing control is achieved by setting a cam mechanism. Usually, the shell carrier is configured as a plurality of positioning blocks, and the plurality of positioning blocks are distributed in a rectangular shape. The rectangle is adapted to the outer contour of the shell carrier, and the positioning blocks of two adjacent sides of one group of the rectangle are set to be elastically retractable. For example, the positioning blocks are set to be fixed blocks and retractable blocks, and a compression spring is set between the fixed block and the retractable block, so that the positioning blocks of the other two adjacent sides are the positioning reference, and the elastically retractable positioning blocks clamp the shell 6100. Therefore, when the shell 6100 is stretched open, the stretching fingers 43311 first squeeze the elastically retractable positioning block with the shell 6100 to leave a stretching space for the other side of the shell 6100, and then the two stretching fingers 43311 stretch the shell 6100 and insert the handle 6800. Compared with the control through the controller and the servo drive mechanism, the cam mechanism is simpler and more reliable.

[0059] In some embodiments, Fig.11As shown, the assembly device 7 4300 may also include a clamping mechanism 4340 for clamping the slide 1 6400 and the slide 2 6500; the clamping mechanism 4340 includes two elastic clamping parts 4341 that contact the slide 1 6400 and the slide 2 6500 respectively and can be elastically clamped, and a clamping driving unit 4342 that drives the two elastic clamping parts 4341 to move along the insertion direction of the slide 1 6400 and the slide 2 6500; the slide 1 6400 and the slide 2 6500 have grooves that match the protrusions on both sides of the handle 6800, and the slide 1 6400 and the slide 2 6500 are clamped by the clamping mechanism 4340 to ensure that the slide 1 6400 and the slide 2 6500 are accurately positioned before being inserted into the handle 6800. In some embodiments, as Fig.11 As shown, the clamping drive unit 4342 is a telescopic cylinder 43421.

[0060] The elastic pressing portion 4341 may be at least partially made of an elastic material, such as eutectic; or may be a mechanism composed of elastic elements such as a spring. Fig.11 As shown, the elastic clamping portion 4341 may include two limit blocks 43411 arranged at intervals along the insertion direction of slide 1 6400 and slide 2 6500, and a clamping shaft 43412 slidably set along the insertion direction of slide 1 6400 and slide 2 6500; the clamping shaft 43412 is in a step shape with a thick middle and thin ends, and the two ends of the clamping shaft 43412 are respectively slidably matched with the two limit blocks 43411, and the end of the clamping shaft 43412 close to the shell 6100 extends out of the corresponding limit block 43411, and a clamping spring 1 43413 is set between the clamping shaft 43412 and at least one of the limit blocks 43411. When the elastic clamping portion 4341 is in a clamping state, the clamping spring 1 43413 is used to provide a clamping force to clamp slide 1 6400 and slide 2 6500.

[0061] In some embodiments, Fig. 9 and Fig.10 As shown, the assembly device 4300 may also include an elastic pressing structure 4350 for pressing the housing 6100. The elastic pressing structure 4350 is fixed to the output end of the lifting drive component 4332 and rises and falls simultaneously with the spreading structure 4330. Before the spreading finger 43311 is inserted into the housing 6100, the elastic pressing structure 4350 first presses the housing 6100 to ensure that the spreading finger 43311 is accurately inserted into the housing 6100. The elastic pressing structure 4350 may have the same structure as the elastic pressing part 4341. In some embodiments, as Fig. 9 and Fig.10As shown, the elastic clamping structure 4350 may include a clamping block 4351 slidably connected to the movable seat 433125 along the lifting direction of the support structure 4330 and a clamping spring 4352 arranged between the clamping block 4351 and the movable seat 433125. When the elastic clamping portion 4341 is in a clamping state, the clamping spring 4352 is used to provide a clamping force for the clamping shell 6100.

[0062] The housing 6100 can be transferred from the housing loading device 1400 to the housing carrier 1200 of the turntable 1100 by a robot. Fig.12 As shown, the shell 6100 is placed on the shell carrier 1200 on the turntable 1100 through the grab module 1, and the grab module 1 is located between the shell feeding device 1400 and the turntable 1100. The grab module 1 can adopt an existing structure, such as the HSP series high-speed grab module of FESTO; another example is the Chinese utility model patent CN208249299U, which is named as an integrated rotating grab mechanism. Of course, other forms can be adopted, and the present invention does not limit it. It is only necessary to install a structure for clamping the shell 6100 at the output end of the grab module 1, such as a clamping claw cylinder.

[0063] Assembly device 1 1300, assembly device 2 2300, assembly device 3 2400, assembly device 4 2500, assembly device 5 3300, assembly device 6 3400 and assembly device 7 4300 can all use manipulators, and only need to configure the corresponding end tool for picking up parts such as sealing gasket 6600 at the end of the manipulator. In some embodiments, assembly device 1 1300 may include a grabbing module 2 1310 disposed between the sealing ring feeding device 1500 and the turntable 1 1100, and a sealing ring 6200 end tool fixed to the grabbing module 2 1310. The sealing ring 6200 end tool may adopt a structure similar to Chinese utility model patent CN202943586U, which is named a clamping assembly mechanism for elastic sealing ring 6200. In other embodiments, such as Fig.13As shown, the end tool of the sealing ring 6200 includes a clamping device 4310-1330 for clamping the sealing ring 6200 in a free state and a clamping device 4310-1340 for clamping the stretched state; an opening mechanism 1320 for stretching the sealing ring 6200 is also arranged between the turntable 1100 and the sealing ring feeding device 1500; the opening mechanism 1320 may include a guide rail slide parallel finger clamp 1322 and two guide rail slide parallel finger clamps 2 respectively installed on the two slides of the guide rail slide parallel finger clamp 1322, and the two slides of the guide rail slide parallel finger clamp 2 are both installed with opening fingers 1321, and the opening directions of the guide rail slide parallel finger clamp 1 1322 and the guide rail slide parallel finger clamp 2 are perpendicular to each other; the guide rail slide parallel finger clamp 1 1322 and the guide rail slide parallel finger clamp 2 can both adopt existing technologies, such as the MHF2 series guide rail slide parallel finger clamp of SMC company. The clamping device 4310-1330 can be a clamping cylinder. When clamping the sealing ring 6200 in a free state, the two fingers of the clamping device 4310-1330 are inserted into the seal, and then the two fingers are opened to support the sealing ring 6200. Then, the grasping module 2 1310 drives the clamping device 4310-1340 to remove the sealing ring 6200 on the opening mechanism 1320, and at the same time drives the clamping device 4310-1330 to put the sealing ring 6200 on the opening mechanism 1320; then, the parallel finger clamp 1 1322 of the guide rail slide and the parallel finger clamp 2 of the guide rail slide move at the same time, driving the four opening fingers 1321 to open, expand the sealing ring 6200, and facilitate the clamping device 4310-1340 to grasp. In some embodiments, such as Fig.13 As shown, the clamping device 4310-1340 includes a retractable core block 1341 and a push sleeve 1342 sleeved outside the core block 1341. The core block 1341 extends out of the push sleeve 1342, and the outer contour of the core block 1341 extending out of the push sleeve 1342 is adapted to the inner wall of the expanded sealing ring 6200. When the sealing ring 6200 is taken out from the opening mechanism 1320, the core block 1341 is inserted into the sealing ring 6200, and the guide rail slide parallel finger clamp 1 1322 and the guide rail slide parallel finger clamp 2 respectively drive the four opening fingers 1321 to close, thereby sleeve the sealing ring 6200 outside the core block 1341. It can be understood that an avoidance groove for avoiding the four opening fingers 1321 can be processed on the core block 1341, and the four opening fingers 1321 can also be set to be retractable, so as to avoid the interference between the core block 1341 and the four opening fingers 1321. In some embodiments, such as Fig.13As shown, the opening mechanism 1320 also includes a lifting cylinder 1323, and the guide rail slide parallel finger clamp 1322 is installed at the output end of the lifting cylinder 1323, so that the four opening fingers 1321 are retractable. When installing the sealing ring 6200, the grabbing module 2 1310 drives the clamping device 4310 2 1340 to move to the shell 6100. After contacting the shell 6100, the core block 1341 gradually retracts, and the push sleeve 1342 continues to move, thereby pushing the sealing ring 6200 into the shell 6100. The extension and retraction of the core block 1341 can be achieved by setting a spring between the core block 1341 and the push sleeve 1342.

[0064] Obviously, the shell 6100 can also be transferred from the turntable to the conveying device 7000 through the structure of the above-mentioned grabbing module 1 or grabbing module 2 1310, and then transferred from the conveying device 7000 to another turntable or discharge.

[0065] The terminal holding auxiliary structure 6300 and the cap 6700 are made of hard materials, so the assembly device 2300 for installing the terminal holding auxiliary structure 6300 into the shell 6100 and the assembly device 63400 for installing the cap 6700 into the shell 6100 can both be completed using the structure of the above-mentioned grasping module 1 or grasping module 2 1310, and it is only necessary to replace the end tool with a clamping cylinder.

[0066] The slide 1 6400 and the slide 2 6500 are also made of hard material, but the slide 1 6400 and the slide 2 6500 need to be inserted into the housing 6100 from the horizontal direction. Therefore, when the assembly device 3 2400 and the assembly device 4 2500 adopt the structure of the above-mentioned grabbing module 1 or grabbing module 2 1310, a telescopic cylinder can be added to the end tool. Specifically, when the grabbing module moves the slide 1 6400 or the slide 2 6500 to the housing carrier 2 2200, the telescopic cylinder pushes the clamping claw of the slide 1 6400 or the slide 2 6500 toward the housing 6100. 00 moves, thereby inserting a part of the slide 1 6400 or the slide 2 6500 into the shell 6100, and then a final pressure telescopic cylinder is arranged on the turntable 2 2100. When the shell carrier 2 2200 on which the slide 1 6400 and the slide 2 6500 are installed is rotated to the final pressure telescopic cylinder, the piston rod of the final pressure telescopic cylinder is extended to push the slide 1 6400 and the slide 2 6500 completely into the shell 6100; the assembly device 3 2400 and the assembly device 4 2500 can also be implemented by a multi-axis robotic arm, which are not listed one by one here, and the present invention does not limit them.

[0067] The sealing gasket 6600 is made of soft material, and the end tool of the assembly device 5 3300 can be a vacuum suction head.

[0068] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
