[0039] Reference Figures 1 to 8 The dart assembly device of the utility model is implemented as follows:

[0040] A dart assembly device comprises: a turntable device 10, a dart shaft feeding device 20, an aluminum ring feeding device 30, a pressing device 40 and a feeding device 50.

[0041] The turntable device 10 includes a plurality of jig components 130. The plurality of jig components 130 circulate along a circular path.

[0042] The dart bar feeding device 20 comprises: a dart bar conveying mechanism 200 and a dart bar loading mechanism 300. The dart bar conveying mechanism 200 is used to continuously supply dart bars, and the dart bar loading mechanism 300 is used to transfer the dart bars from the dart bar conveying mechanism 200 to the fixture component 130 of the loading station.

[0043] The aluminum ring feeding device 30 includes: an aluminum ring conveying mechanism 400 and an aluminum ring fitting mechanism 500. The aluminum ring conveying mechanism 400 is used to continuously supply dart aluminum rings, and the aluminum ring fitting mechanism 500 is used to fit the dart aluminum rings from the aluminum ring conveying mechanism 400 into the dart dart shaft of the fixture component 130 of the ring fitting station.

[0044] The pressing device 40 is used to press the dart aluminum ring and the dart shaft.

[0045] The unloading device 50 is used to unload the jig component 130 in the unloading station.

[0046] In actual use, the jig component 130 of the turntable device 10 can sequentially reach the loading station, the ferrule station, the pressing station and the unloading station. The dart bar loading mechanism 300 transfers the dart bar from the dart bar conveying mechanism 200 to the jig component 130 at the loading station to realize the loading operation of the jig component 130. When the jig component 130 that has completed loading moves to the ferrule station, the aluminum ring fitting mechanism 500 transfers the dart aluminum ring from the aluminum ring conveying mechanism 400 to the jig component 130, and inserts it onto the dart bar. The dart bar with the dart aluminum ring moves to the pressing station with the jig component 130 and is pressed by the pressing device 40. When the dart bar that has completed the ferrule processing moves to the unloading station, the corresponding jig component 130 is taken away by the unloading device 50 to realize the unloading of the processed product.

[0047] The turntable device 10 includes a rotating disk 110 and a rotation driving member 120. The rotating disk 110 is in a disk shape, and the rotation driving member 120 is used to drive the rotating disk 110 to rotate. The rotation axis of the rotating disk 110 extends in the up-down direction.

[0048] In this embodiment, the turntable device 10 is a four-station turntable. The loading station is arranged at the rear end of the turntable device 10, the ring station is arranged at the left end of the turntable device 10, the pressing station is arranged at the front end of the turntable device 10, and the unloading station is arranged at the right end of the turntable device 10.

[0049] The number of the jig components 130 is four. The four jig components 130 are evenly distributed around the circumference of the rotating disk 110. The jig component 130 has a jig clamping claw for clamping the dart shaft, and the jig clamping claw includes two claw pieces arranged in pairs on the left and right and elastically pressed against each other. The two claw pieces arranged in pairs have clamping grooves facing each other, and the clamping grooves extend in the up-down direction, so that when the dart shaft is clamped in the clamping groove, its axial direction extends in the up-down direction.

[0050] In this embodiment, the dart shaft conveying mechanism 200 includes: a dart shaft vibration plate 210 and a dart shaft direct vibration 220. The dart shaft direct vibration 220 is arranged in the front-to-back direction. The dart shaft vibration plate 210 is arranged at the rear side of the dart shaft direct vibration 220 and is connected to the dart shaft direct vibration 220. The dart shaft direct vibration 220 has a dart shaft conveying channel extending front and back. The front end of the dart shaft conveying channel has a feed port.

[0051] The dart shafts are screened and supplied through the dart shaft vibration plate 210, so that the dart shafts can continue to enter the dart shaft direct vibration 220 in the same direction. The dart shaft direct vibration 220 can continuously transport the dart shafts thereon forward by vibration.

[0052] The dart bar feeding mechanism 300 includes a feeding clamp 310 and a feeding driving component 320 .

[0053] The feeding clamp 310 uses a clamping cylinder to drive two symmetrically arranged clamping members to press against each other or move away from each other. The structure of the clamping members can refer to the structure of the claws of the fixture clamp, and the clamping members and the claws both clamp and grab the dart shaft through a groove structure arranged in a contoured manner.

[0054] The feeding drive component 320 is used to drive the feeding jaw 310 to move between the feeding port and the fixture component 130 at the feeding station. Specifically, the feeding drive component 320 includes: a feeding drive unit 321, a driving slide 322, a flip seat 323 and a guide plate 324.

[0055] The feeding drive unit 321 is used to drive the driving slide 322 to move forward and backward. The middle part of the flip seat 323 has a connecting shaft. The connecting shaft extends in the left-right direction and is rotatably connected to the driving slide 322.

[0056] In this embodiment, the driving slide 322 is arranged on the front right side of the feeding port. The left end of the flip seat 323 is block-shaped, and the feeding clamp 310 is installed on the left end of the flip seat 323 and is aligned with the feeding port front and back. The feeding clamp 310 is arranged along the radial direction of the connecting shaft. The guide plate 324 is arranged on the right side of the driving slide 322. The left side of the guide plate 324 has a guide groove 3241, and the right end of the flip seat 323 is transmission-connected to the guide groove 3241.

[0057] The right end of the flip seat 323 has a transmission end 3231. The transmission end 3231 is eccentrically arranged with respect to the connecting shaft, and the transmission end 3231 is movably embedded in the guide groove 3241. The guide groove 3241 includes a translation section and a flip section. The translation section is arranged at the rear side of the flip section and is connected to the flip section end to end. The translation section extends in the front-to-back direction, and the flip section extends upward in an arc transition.

[0058] When the transmission end 3231 is in the translation section, the feeding clamp 310 is arranged backward. When the feeding drive unit 321 drives the driving slide 322 to move to the rear limit position, the transmission end 3231 is in the rear section of the translation section. At this time, the feeding clamp 310 is in the front side of the feeding port, and the feeding clamp 310 can clamp the dart shaft in the feeding port. In the process of the feeding drive unit 321 driving the driving slide 322 to move forward: the transmission end 3231 first moves along the translation section, so that the feeding clamp 310 and the driving slide 322 translate forward; when the transmission end 3231 moves along the flipping section, the driving slide 322 still moves forward, but the transmission end 3231 swings upward relative to the connecting shaft, so that the flip seat 323 rotates relative to the driving slide 322, and the feeding clamp 310 flips downward around the connecting shaft, so that the dart rod on it swings downward to the fixture component 130 of the feeding station, thereby realizing the loading and placing action of the dart rod.

[0059] In a further embodiment, the jig member 130 has a positioning groove for positioning the lower end of the dart shaft. The positioning groove is arranged below the jig clamp and opens upward. The dart shaft feeding mechanism 300 also includes a lifting drive member 330. The lifting drive member 330 is used to drive the feeding drive member 320 and the feeding clamp 310 to move up and down.

[0060] Specifically, the lifting drive component 330 includes: a lifting drive unit 331 and a lifting platform 332. The lifting platform 332 is slidably arranged in the up-down direction. The lifting drive unit 331 has a lifting drive end that is transmission-connected to the lifting platform 332 and enables the lifting platform 332 to move up and down relative to the turntable device 10. The driving slide 322 is slidably installed on the lifting platform 332 in the front-back direction. The guide plate 324 is arranged beside the driving slide 322 and is fixedly connected to the lifting platform 332.

[0061] When the loading clamp 310 clamps the dart shaft and turns downward to the up-down direction, the dart shaft is aligned with the positioning groove. At this time, the lifting drive unit 331 drives the lifting platform 332 to move downward, so that the lower end of the dart shaft is inserted into the positioning groove, and the fixture clamp of the fixture member 130 clamps the dart shaft.

[0062] Furthermore, in order to facilitate the dart bar feeding mechanism 300 to take materials, a material blocking mechanism 230 is provided at the front side of the feed port. The material blocking mechanism 230 includes: a material blocking member 231 and a material blocking driving unit 232. The material blocking member 231 is provided at the front side of the feed port, and the material blocking member 231 has a material blocking groove extending front and back. The rear end of the material blocking groove is aligned and connected with the dart bar conveying channel front and back, and the front end of the material blocking groove has a material blocking portion. The material blocking driving unit 232 is used to drive the material blocking member 231 to rise and fall.

[0063] In actual use, the dart shaft moves forward under the action of the dart shaft direct vibration 220. When the material blocking member 231 is at the front side of the feed port, the front end of the dart shaft can be transported forward to the material blocking groove, and the material blocking portion can limit the dart shaft so that the front section of the dart shaft is exposed in the dart shaft conveying channel. When the feeding clamp 310 takes the dart shaft, the material blocking driving unit 232 drives the material blocking member 231 to move downward relative to the material blocking conveying channel, so that the front section of the dart shaft is completely exposed, which is convenient for the clamping and grabbing of the dart shaft.

[0064] The jig member 130 that has completed the loading of the dart shaft moves from the loading station to the ring station.

[0065] In this embodiment, the aluminum ring conveying mechanism 400 includes: an aluminum ring vibration plate 410 and an aluminum ring direct vibration 420. The aluminum ring direct vibration 420 is arranged in the left-right direction. The aluminum ring direct vibration 420 has an aluminum ring conveying channel extending in the left-right direction. The aluminum ring vibration plate 410 and the ring station are respectively arranged at the left and right ends of the aluminum ring direct vibration 420. The left end of the aluminum ring conveying channel is connected to the aluminum ring vibration plate 410, and the right end of the aluminum ring conveying channel has a discharge end.

[0066] The dart aluminum rings are supplied through the aluminum ring vibration plate 410, so that the dart aluminum rings can continuously enter the aluminum ring direct vibration 420 one by one. The aluminum ring direct vibration 420 can continuously transport the dart aluminum rings on it to the right through vibration.

[0067] The aluminum ring fitting mechanism 500 includes an aluminum ring taking and placing component 510 and a transfer component 520 .

[0068] The aluminum ring picking and placing component 510 is used to pick up and place the aluminum ring. The transfer component 520 is used to drive the aluminum ring picking and placing component 510 to move. In this embodiment, the transfer component 520 includes an X-axis drive component arranged along the left-right direction and a Z-axis drive component arranged along the up-down direction. The X-axis drive component and the Z-axis drive component are respectively used to drive the aluminum ring picking and placing component 510 to move along the left-right direction and the up-down direction, so that the aluminum ring picking and placing component 510 can perform translation and lifting actions, thereby realizing the picking and placing of the aluminum ring. The X-axis drive component and the Z-axis drive component can adopt linear drive components such as cylinders, electric push rods, hydraulic push rods or screw nut drive components.

[0069] The aluminum ring picking and placing component 510 includes: an aluminum ring guide rod 511, a ring knocking sleeve 512 and a ring knocking driving unit 513. The aluminum ring guide rod 511 is roughly cylindrical, and the lower end of the aluminum ring guide rod 511 has an aluminum ring guide column 5111 in a conical shape, which is wide at the top and narrow at the bottom. The ring knocking sleeve 512 is coaxially sleeved on the aluminum ring guide rod 511. The ring knocking driving unit 513 is used to drive the ring knocking sleeve 512 to move up and down relative to the aluminum ring guide rod 511.

[0070] In actual use, the aluminum ring guide rod 511 moves downward and is inserted into the dart aluminum ring. During the insertion process, the inner ring of the dart aluminum ring is tightly sleeved on the aluminum ring guide column 5111, thereby realizing the movement of the dart aluminum ring. The dart aluminum ring moves to the sleeve station with the aluminum ring guide rod 511 and is aligned with the dart dart shaft on the fixture component 130. At this time, the ring unseating driving unit 513 drives the unseating sleeve 512 to move downward relative to the aluminum ring guide rod 511. The unseating sleeve 512 can drive the dart aluminum ring on the aluminum ring guide column 5111 to break away from the aluminum ring guide column 5111 and move downward, so that it falls and is sleeved on the dart dart shaft, realizing the sleeve action of the dart dart shaft.

[0071] It is worth noting that the diameters of the aluminum ring guide column 5111 and the de-hooking sleeve 512 need to be set according to the inner and outer diameters of the dart aluminum ring.

[0072] In order to avoid the aluminum ring conveying mechanism 400 from being affected by inaccurate positioning of the aluminum ring during the conveying process, a dividing mechanism 430 is provided at the discharge end. The dividing mechanism 430 includes: a dividing block 431 and a dividing driving unit 432. The dividing block 431 is arranged at the discharge end. The left side of the dividing block 431 is close to the discharge end and is provided with a dividing trough 4311 flush with the discharge end. The dividing trough 4311 is coaxially provided with a avoiding hole. The dividing driving unit 432 has a dividing driving end which is transmission-connected to the dividing block 431 and enables the dividing block 431 to move forward and backward relative to the aluminum ring conveying mechanism 400.

[0073] The material distribution drive unit 432 drives the material distribution block 431 to move forward and backward. When the material distribution trough 4311 is aligned with the discharge end, the dart aluminum ring at the right end of the aluminum ring conveying channel can fall into the material distribution trough 4311 from the discharge end. Then, the material distribution block 431 moves forward and backward, so that the material distribution trough 4311 and the discharge end are staggered front and back, and while the material is blocked at the discharge end, the material distribution trough 4311 drives a single dart aluminum ring to achieve material distribution, which facilitates the aluminum ring picking and placing component 510 to pick up the dart aluminum ring. The aluminum ring guide rod 511 can extend into the avoidance hole without interfering with the material distribution block 431, so that the inner ring of the dart aluminum ring can be tightly sleeved on the aluminum ring guide column 5111.

[0074] After the dart aluminum ring is put on the dart shaft, the fixture component 130 moves from the ring-putting station to the pressing station.

[0075] The pressing device 40 comprises: a pressing slide 610, a pressing needle 620 and a pressing driving member 630. The pressing body is arranged above the pressing station and connected to the pressing slide 610. The lower part of the pressing needle 620 is cylindrical. The pressing driving member 630 has a pressing driving end which is transmission-connected to the pressing slide 610 and moves the pressing slide 610 up and down.

[0076] In actual use, the pressing drive component 630 drives the pressing slide 610 to move downward, and the lower part of the pressing needle 620 is coaxially inserted into the dart shaft of the jig component 130 of the pressing station, and the dart aluminum ring is pressed onto the dart shaft through the lower end of the pressing needle 620.

[0077] In order to avoid product and equipment damage caused by excessive extrusion, in a further embodiment, the pressing needle 620 is elastically connected to the pressing slide 610 in the up and down direction.

[0078] Specifically, the upper end of the pressing needle 620 is cylindrical in shape and is connected to the pressing slide 610 by sliding up and down. A retaining ring is provided in the middle of the pressing needle 620. A spring 640 is provided between the retaining ring and the pressing slide 610. The spring 640 is coaxially sleeved on the outer side of the pressing needle 620, and the upper and lower ends of the spring 640 are elastically abutted against the pressing slide 610 and the retaining ring respectively. When the pressing slide 610 moves downward, the pressing needle 620 can be elastically pressed against the upper side of the dart aluminum ring to achieve tightening, and the pressing needle 620 can compress the spring 640 to move upward relative to the pressing slide 610.

[0079] Furthermore, the pressing slide 610 is provided with a position detection unit 611 for sensing the height position of the pressing pin 620. In this embodiment, the position detection unit 611 is a proximity switch. The position detection unit 611 is installed on the pressing slide 610 and detects the upper end of the pressing pin 620.

[0080] In order to reduce the load of the turntable device 10 in the pressing station, a top column 650 is provided on the lower side of the pressing station. The upper end of the top column 650 has a horizontally extending supporting surface. The lower side of the rotating disk 110 has a supporting surface. The supporting surface is arranged one by one with the jig component 130 up and down. The supporting surface is flush with the supporting surface. When the jig component 130 rotates to the pressing station, the supporting surface is aligned and fits with the supporting surface, so that when the jig component 130 is pressed, the top column 650 can provide support for the rotating disk 110.

[0081] The unloading device 50 includes: an unloading clamp 710 and an unloading transfer module 720. The unloading transfer module 720 is used to drive the unloading clamp 710 to move, so as to remove the processed dart shaft from the jig component 130 of the unloading station. The specific structure of the unloading clamp 710 can refer to the jig clamp and the loading clamp 310. The specific structure of the unloading transfer module 720 can refer to the transfer component 520.

[0082] Furthermore, the unloading device 50 is also provided with an unloading chute 730 and a receiving tray 740.
