[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, an example of the present application provides a positioning ring feeding mechanism of an automatic assembly machine, the mechanism includes a turntable mechanism 100, a transfer mechanism 200 is arranged on the upper side of the turntable mechanism 100, a feeding mechanism 300 is arranged on the outer side of the turntable mechanism 100, the transfer mechanism 200 includes a transverse conveying component 201 installed on a bracket and a longitudinal conveying component 202 installed on the transverse conveying component 201, a support plate 203 is arranged on the longitudinal conveying component 202, a longitudinal guide rail 204 is arranged at one end of the support plate 203, a slider 205 is arranged on the longitudinal guide rail 204, a clamping mechanism is arranged on the slider 205, a sensing sheet 207 is arranged on the clamping mechanism, and the sensing sheet 207 can be L-shaped, and the support plate 203 is also provided with a position sensor 208, and the position sensor 208 is provided with a slot, and the end of the sensing sheet 207 is inserted into the slot.

[0036] The feeding mechanism 300 of the present application is used to supply the positioning ring 400. The above-mentioned transfer mechanism 200 is used to place the positioning ring 400 on the feeding mechanism 300 into the fixture 101 on the turntable mechanism 100. A plurality of fixtures 101 can be arranged along the circumferential direction on the above-mentioned turntable mechanism 100. After the positioning ring 400 is placed in a fixture 101, the turntable mechanism 100 rotates so that the positioning ring 400 can be placed in the next fixture 101.

[0037] The above-mentioned transverse conveying component 201 of the present application can be a cylinder component, and the above-mentioned longitudinal conveying component 202 can also be a cylinder component.

[0038] The position sensor 208 of the present application may employ an existing through-beam photoelectric sensor with a slot.

[0039] Specifically, after the clamp mechanism picks up the positioning ring 400 on the feeding mechanism 300, the clamp mechanism can move to the top of the fixture 101 under the transportation of the horizontal conveying component 201, and then the longitudinal conveying component 202 drives the support plate 203 to descend, thereby driving the clamp mechanism to descend. If the positioning of the clamp mechanism and the fixture 101 is accurate, the positioning ring 400 will smoothly enter the interior of the fixture 101. If the positioning of the clamp mechanism and the fixture 101 deviates, this will cause the positioning ring 400 on the clamp mechanism to not be placed inside the fixture 101, that is, the positioning ring 400 is placed on the edge of the fixture 101, which will cause the longitudinal conveying component 202 to still move downward, but the clamp mechanism cannot move downward due to the blocking effect of the fixture 101, thereby causing the induction sheet 207 connected to the clamp mechanism to separate from the position sensor 208, thereby prompting the position sensor 208 to generate an alarm signal. If the position sensor 208 is connected to the host computer, the corresponding alarm information can be displayed on the host computer. If the position sensor 208 is connected to an alarm, the alarm will sound an alarm.

[0040] In one embodiment, if Figure 2 As shown, the bracket is provided with an extension arm 209, and the end of the extension arm 209 is provided with a first detection sensor 210, and the first detection sensor 210 faces the upper end of the feeding mechanism 300. Specifically, the feeding mechanism 300 is used to transport the stacked positioning rings 400 upward one by one. The first detection sensor 210 is used to determine whether there is a positioning ring 400 at the uppermost end of the feeding mechanism 300.

[0041] In one embodiment, if Figures 2 to 5As shown, the clamping mechanism includes a driving cylinder 211, a connecting block 212, a driving plate 215, an elastic member 216, a guide block 213 and two clamping arms 214. The upper end of the driving cylinder 211 is connected to the induction plate 207. The lower end of the driving cylinder 211 is connected to the connecting block 212, and the connecting block 212 is connected to the guide block 213. The connecting block 212 is also provided with a corresponding groove for the driving plate 215 to move. The guide block 213 is connected to the slider 205. The guide block 213 is provided with a driving plate guide hole 2131 and a clamping arm guide hole 2132 for guiding the lateral movement of the clamping arm 214. The middle part of the driving plate guide hole 2131 can be made larger to be used by the elastic member 216. The driving plate 215 is arranged in the driving plate guide hole 2131. The driving cylinder 211 is used to drive the driving plate 215 to move downward. Two inclined guide holes 2151 are arranged on the driving plate 215. One end of the clamping claw arm 214 is located in the corresponding clamping claw arm guide hole 2132 and is provided with a pin shaft 217. The pin shaft 217 is inserted into the corresponding guide hole on the driving plate 215. A receiving groove is also arranged on the driving plate 215. The elastic member 216 is arranged in the receiving groove. One end of the elastic member 216 abuts against the end face of the receiving groove, and the other end of the elastic member 216 abuts against the inner wall of the guide block 213.

[0042] Specifically, the elastic member 216 may be an elastic element such as a spring.

[0043] Specifically, the two inclined guide holes 2151 may be arranged in such a manner that the upper ends are close to each other and the lower ends are separated from each other, or the upper ends are separated from each other and the lower ends are close to each other.

[0044] Specifically, the two inclined guide holes 2151 are arranged in such a manner that the upper ends are close to each other and the lower ends are separated from each other. When the driving cylinder 211 extends, it will press the driving plate 215 downward, and the driving plate 215 moves downward. The guide holes on the driving plate 215 will cause the clamping claw arms 214 to contract and move, and then the two clamping claw arms 214 can extend into the interior of the positioning ring 400. When the driving cylinder 211 retracts, the driving plate 215 moves upward under the action of the elastic member 216, and the two clamping claw arms 214 extend outward under the action of the guide holes, and then the positioning ring 400 can be supported and clamped. When the driving cylinder 211 presses the driving plate 215 again, the clamping claw arms 214 contract and the positioning ring 400 can be released. The elastic member 216 is used to drive the two clamping claw arms 214 to open, and this force is relatively moderate and is not easy to damage the surface of the positioning ring.

[0045] It is understandable that if the upper ends of the two inclined guide holes 2151 are separated from each other and the lower ends are close to each other, such an arrangement allows the two clamping arms 214 to extend outward during the downward pressing process of the driving cylinder 211, thereby clamping the inner support of the positioning ring 400.

[0046] In one embodiment, the lower end of the clamp arm 214 is provided with a downward pressing surface 2142, and a support block 2141 protruding downward is provided on one side of the downward pressing surface 2142. The support block 2141 is used to extend into the positioning ring 400 to achieve internal support and clamping of the positioning ring. The downward pressing surface 2142 is used to limit the upper end surface of the positioning ring 400. Since both clamp arms 214 are provided with downward pressing surfaces 2142, both ends of the positioning ring 400 are limited, so that when the positioning ring 400 is placed, one end of the positioning ring 400 will not be tilted up.

[0047] In one embodiment, a second detection sensor 500 is disposed at the lower end of one of the clamping arms 214, and the second detection sensor 500 is used to detect whether there is a positioning ring 400 between the two clamping arms 214. Specifically, a horizontal through hole and a vertical through hole that are connected can be opened at the lower end of the clamping arm 214, and the second detection sensor 500 is disposed in the horizontal through hole, and the vertical through hole is used for optical path detection.

[0048] In one embodiment, limit blocks 206 are respectively disposed at both ends of the longitudinal guide rail 204 , and the limit blocks 206 are connected to the support plate 203 . The limit blocks 206 are used to limit the moving position of the slider 205 .

[0049] In one embodiment, if Figure 6 As shown, the feeding mechanism 300 includes a base 301, on which a rotating motor 302 and a rotating disk 303 connected to the rotating motor 302 are arranged, and on which a plurality of bin mounting seats 304 are arranged, for example, four bin mounting seats 304 can be arranged. A magazine bin 305 is detachably connected to each bin mounting seat 304. A lead screw lifting mechanism 306 is also arranged on the base 301, and a lifting assembly is arranged on one side of the lead screw lifting mechanism 306, and the lead screw lifting mechanism 306 is connected to the lifting assembly, and the lifting assembly is used to lift the positioning ring 400 on the feeding magazine. The lead screw lifting mechanism 306 is used to drive the lifting assembly to move up and down. The lifting assembly is used to lift the positioning rings 400 stacked on the magazine bin 305 one by one.

[0050] In one embodiment, the lifting assembly includes a connecting plate 307 and a rotating assembly 308, wherein the connecting plate 307 is respectively connected to the screw lifting mechanism 306 and the rotating assembly 308, and two lifting rods 309 are installed on the rotating assembly 308. A support arm 310 is provided at the upper end of the lifting rod 309, and the rotating assembly 308 is used to drive the lifting rod 309 to rotate.

[0051] Specifically, there are many implementations of the rotating assembly 308. For example, the rotating assembly 308 includes a base body, in which two gears are arranged, each gear is connected to a lifting rod 309, a rack is arranged between the two gears, the gears are meshed with the racks, and the racks are connected to a cylinder. The cylinder drives the rack to move, and the rack drives the gear to rotate, thereby causing the lifting rod 309 to rotate. The rotation of the lifting rod 309 drives the support arm 310 to rotate. When it is necessary to lift the positioning ring 400, the support arm 310 rotates to the bottom of the positioning ring 400, so that the positioning ring 400 can be lifted by the support arm 310. When all the positioning rings 400 on a magazine bin 305 are picked up, the support arm 310 moves downward to reset and rotates outward, and then the rotating disk 303 rotates, so that another magazine bin 305 filled with positioning rings 400 rotates to the loading station, and then the support arm 310 rotates inward to the bottom of the stacked positioning rings 400. This can then lift the retaining ring 400 upward via the support arm 310 .

[0052] In one embodiment, a linear bearing 311 is disposed on the base 301 , and the lifting rod 309 passes through the linear bearing 311 .

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
