[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-Figure 13The automatic assembly machine for can body and can cover of the present invention comprises a first turntable 11, a second turntable 12, and a main rotating shaft 13. The first turntable 11 and the second turntable 12 rotate synchronously, and the first turntable 11 is located on the side of the second turntable 12. The driving shaft 13 is connected with the pulleys of the first turntable 11 and the second turntable 12 respectively. A can cover feeding device 2 and a can cover needle threading device 3 are arranged in sequence around the rotation direction of the first turntable 11, and a can body feeding device 5, a first needle threading device 7, a second needle threading device 8, and a finished product delivery device 9 are arranged in sequence around the rotation direction of the second turntable 12. The automatic assembly machine for can body and can cover of the present invention is provided with a main rotating shaft motor, which is used to drive the driving rotating shaft 13 to rotate, thereby driving the first turntable 11 and the second turntable 12 to rotate synchronously counterclockwise, and driving the rotating frame push plate 54 installed on the push frame plate 131, the can cover unloading push rod 95, and the delivery push block 95 to move up and down through the longitudinal rotating shaft 132. Among them, the turntable switching box 133 has a switching box input shaft extending outward from the side and a switching box output shaft extending outward from the top, the switching box pulley is installed on the switching box input shaft, the first turntable 11 or the second turntable 12 is installed on the switching box output shaft, and a motion mechanism that allows the switching box output shaft to make intermittent motion is installed between the switching box input shaft and the switching box output shaft, thereby realizing that the continuous motion of the active shaft 13 transmitted to the switching box input shaft can be switched to intermittent motion through the switching box output shaft to make the first turntable 11 and the second turntable 12 make an intermittent motion rotating in the horizontal direction. The rotation of the first turntable 11 and the second turntable 12 is to rotate to 45°, then stop for a period of time, then rotate 45°, and then stop for a period of time. During the time when the first turntable 11 and the second turntable 12 are stationary, the can cover feeding device 2, the first needle threading device 7 and other devices complete their respective work processes. A can body conveyor belt is installed on the side of the can body feeding device 5, and the can body conveyor belt is directly opposite to the can body pushing groove of the can body pushing frame 52.

[0034] When the present invention is working, workers place multiple can bodies on the can body conveyor belt, and at this time, the can body axis pinholes of the can bodies face the direction close to the second turntable 12, and the can cover vibration plate on the can cover conveying trough 21 conveys the can covers to the can cover feeding trough 21 in an orderly manner, and at this time, the can cover axis pinholes face the direction away from the first turntable 11. The main rotating shaft 13 rotates to drive the first turntable 11 and the second turntable 12 to rotate; the can cover conveying trough 21 on the can cover feeding device 2 conveys the can covers, and the can cover conveying baffle 22 rises and no longer blocks the conveying of the can covers, so that the can covers can be conveyed to the pushing trough plate 23. After the pushing trough plate 23 is placed with can covers, the can cover conveying baffle 22 descends to block the pushing of new can covers, and the trough plate push rod device 24 pushes the pushing trough plate 23 forward to the bottom of the can cover transport device 14, and the vertically movable push frame 142 on the can cover transport device 14 descends until the suction cup 143 contacts the can cover, and the air inside the suction cup 143 is sucked out to tighten the can cover. The can cover is tightly adsorbed, the vertical moving push frame 142 rises, the horizontal moving guide slider device 141 moves forward to place the adsorbed can cover just above the can cover groove 111 on the first turntable 11, the vertical moving push frame 142 descends until the adsorbed can cover is placed in the can cover groove 111, air is injected into the inner side of the suction cup 143 to release the adsorption effect on the can cover, the vertical moving push frame 142 rises, the horizontal moving guide slider device 141 moves backward until the suction cup 143 on the vertical moving push frame 142 is placed just above the pushing slot plate 23, and the slot plate push rod device 24 pulls the pushing slot plate 23 back to the side of the can cover conveying slot 21.

[0035] Then the first turntable 11 rotates 45°, stops, rotates 45° again, stops, rotates 45° again, stops, and rotates 45° again until the can cover groove 111 with the can cover is placed on the side of the can cover needle threading device 3, the axial needle on the axial needle conveying device 36 is pushed into the axial needle hole frame 39, and the longitudinal movable plate push rod pushes the longitudinal movable plate 38 forward to push the axial needle hole frame 39 with the axial needle forward until the axial needle is located directly above the clamping needle base, and the lateral movable plate push rod pushes the lateral movable plate The movable plate 37 makes the shaft pin hole frame 39 away from the clamping pin base frame, and at the same time, the slide rod push rod device controls the clamping slide rod 35 to rise and clamp the shaft pin to the bottom end of the clamping rod 34; the motor of the can cover needle threading device rotates, and the clamping rod cam 321 pushes the clamping rod 34 so that the clamping rod 34 makes a swinging movement with its lower end toward the can cover, and at the same time, the clamping frame cam 323 rotates to push the shaft hole clamping frame 311 down to the shaft hole clamping to tighten the can cover shaft hole, and the clamping rod 34 with the shaft pin clamped swings until its shaft pin is completely facing the can cover. The side push protrusion 322 pushes the swing rod protrusion 341 to make the clamp rod swing rod 33 move sideways, so that the clamp rod 34 inserts the clamped shaft pin into the shaft hole of the tank cover; then the slide rod push rod device controls the clamp slide rod 35 to descend to release the clamping effect on the shaft pin, and at the same time, the side push protrusion 322 continues to rotate, disengaging from the push on the swing rod protrusion, and under the action of the rebound device, the clamp rod swing rod 33 is pushed back, so that the clamp rod 34 and the clamp slide rod 35 are completely separated from the shaft pin; the clamp rod cam 321 Continue to rotate, no longer push the clamping rod 34, because the weight of the swing point of the clamping rod 34 and the clamping slide bar 35 is not as heavy as the weight of the lower end, the clamping rod 34 swings back to contact the clamping rod cam 321 again, and resets, and the supporting clamp frame cam 323 continues to rotate to release the downward push on the shaft hole supporting clamp frame 311, and the shaft hole supporting clamp frame 311 rises and resets under the action of the rebound device, and the worker takes out the assembled can cover, completing one process of the can cover feeding device 2.

[0036] The conveyor belt on the can body conveyor belt works to push the can body into the can body pushing groove of the can body pushing rack 52, and then the can body pushing rack 52 pushes forward to push the can body into the can body rotating rack, and the small magnet installed on the can body rotating rack absorbs the can body tightly; at the same time, the can body feeding baffle on the can body pushing rack 52 moves to the can body conveyor belt to prevent the can body that has not been transported to the can body pushing groove from moving. Then the can body rotating plate 53 rotates 180° until the can body rotating rack with the can body is directly below the can body rack 17 on the second turntable 12, and the main rotating shaft 13 rotates to drive the rotating rack push plate 54 to push up, pushing the can body into the can body rack 17, and then the rotating rack push plate 54 descends and resets. At this time, the can body is absorbed by the small magnet installed on the can body rack 17.

[0037] Then the first turntable 11 rotates 45°, stops, and rotates 45° again. At the same time, the second turntable 12 rotates 45°, stops, and rotates 45° again. The rotation of the second turntable 12 pushes the can cover and can body rack 15 into the arc baffle 131. The arc baffle 131 pushes the rack push plate 19 inward by pushing the push plate roller 191, thereby pushing the can cover groove 16 inward to a position where the can cover transport device 14 can put the transported can cover into the can cover groove 16, and a certain amount of movable space is left between the can cover groove 16 and the can body rack 17. At this time, the can cover groove 111 with the can cover with the axis pin and the can cover and body rack 15 with the can body are both placed on the can cover transportation device 14 between the first turntable 11 and the second turntable 12, and the vertically movable push frame 142 descends until the suction cup 143 contacts the can cover with the axis pin installed on the can cover groove 111, and the air inside the suction cup 143 is extracted to tightly adsorb the can cover, and the vertically movable push frame 142 rises, and the horizontally movable guide rail slider device 141 moves to place the adsorbed can cover on the can cover groove 16 of the can cover and body rack 15 on the second turntable 12, and the vertically movable push frame 142 descends until the adsorbed can cover is placed in the can cover groove 16, and air is injected into the inside of the suction cup 143 to release the adsorption effect on the can cover, and the vertically movable push frame 142 rises, and the horizontally movable guide rail slider device 141 moves until the suction cup 143 on the vertically movable push frame 142 is placed on the can cover groove 111 on the first turntable 11.

[0038] Then the second rotating disk 12 rotates 45°, and the can body rack 15 with the can body and the can cover with the axial pin is placed under the first needle threading device 7. First, the first rotating shaft 77 rotates, driving each cam to rotate, and the rod rack cam 773 pushes the first rod rack 72 downward, so that the can cover groove screw rack 75 is pressed to the can cover groove 16 and the can cover groove 16 is rotated to a certain angle, so that the can cover axial pin hole is aligned with the can body axial pin hole, and the axial pin installed on the can cover axial pin hole is facing the striker 76. Then, when the first rod rack 72 descends, the rod cam 772 first allows the limit rod 74 to swing forward, and then removes the tightening effect on the limit rod 74. Under the action of the rebound device, the limit rod 74 is reset, so that the limit rod 74 can bypass the inner curling edge in the case where the can body is provided with an inner curling edge and is placed in the can body. At this time, the side of the limit rod 74 is facing the opening of the can body axial pin hole to prepare for limiting the maximum insertion distance of the axial pin. Then, when the first rod frame 72 drops to the lowest position and one side of the limiting plug 74 faces the can body axis pin hole, the push rod cam 771 pushes the lower end of the first push rod 73 to swing to the left, and then removes the tightening effect on the first push rod 73, allowing the first push rod 73 to swing back naturally, hitting the striker limiting cap of the striker 76, and the striker 76 hits the axis pin and moves toward the can body axis pin hole, and finally stops on the limiting plug 74. Finally, the rod frame cam 773 removes the tightening effect on the first rod frame 72, and the first rod frame 72 rises under the action of the rebound device; at the same time, the plug cam 772 pushes the limiting plug 74 to swing forward, so that the first rod frame 72 drives the limiting plug 74, the first push rod 73, and the can cover groove screw frame 75 to rise. At this time, the can cover and the can body are connected in series by the axis pin into a whole. And the can body is no longer adsorbed by the magnet on the can body frame.

[0039] Then the second rotating disk 12 rotates 45 degrees until the can cover and body frame 15 is placed under the second needle threading device 8. The second rotating shaft 83 on the second needle threading device 8 rotates, driving the collision block rod cam 831, the insertion rod cam 832, and the rod frame cam 833 to rotate, thereby driving the second rod frame 82, the collision block rod 85, and the insertion rod 86 to move. The rod frame cam 833 drives the second rod frame 82 to descend and drives the various components installed on the second rod frame 82 to descend. In the process of the descent, the collision block rod cam 831 drives the collision block rod 85 to swing outward first and then inward to the original position, so that The collision plate 87 can bypass the inner curling edge of the can mouth of the can body and be placed in the can mouth. At this time, the collision block arranged on the collision plate 87 is located outside the right end of the axis pin and is ready to push the axis pin. The collision rod 85 swings inward, so that the can body top groove 851 arranged on the collision rod 85 hits the can body axis pin hole and pushes the can body and the can cover to the can cover top frame 84 together, so that the top frame groove on the can cover top frame 84 presses the can cover axis pin hole tightly, that is, the collision rod 85 and the can cover top frame 84 form a clamp. The substructure "clamps" the can cover shaft pin hole and the can body shaft pin hole tightly, aligns the left opening of the can cover shaft pin hole with the left opening of the can body shaft pin hole, ensures that the shaft pin can smoothly pass through the can body shaft pin hole during operation, and then the plunger cam 832 inserts the inclined plunger 86 to the inclined surface on the bump plate 87 between the bump plate 87 and the bump rod 85, thereby driving the bump plate 87 to move to the left, so that the bump directly pushes the shaft pin to the left and bumps it to the specified assembly position Finally, as the second rotating shaft 83 rotates, the cams are driven to rotate to remove the force acting on the second rod frame 82, the impact block rod 85, and the insertion rod 86. Under the action of each rebound device, the second rod frame 82 rises, driving the impact block rod 85, the insertion rod 86, and the impact block plate 87 to rise. At this time, the impact block rod 85 drives the impact block plate 87 to swing upward so that it can bypass the inner curling edge of the can body and the can mouth and rise smoothly. The insertion rod 86 makes an upward swinging motion relative to the impact block rod 85 to reset the impact block plate 87.

[0040] Then the second turntable 12 rotates 45° until its can body rack 17 is located directly above the can cover unloading push rod 95, and the main rotating shaft 13 rotates to drive the can cover unloading push rod 95 to push up, through the can cover groove 16, the can cover platform, and the can cover unloading hole on the can cover movable platform 18, and the can cover that has been combined with the can body into a whole and is still placed in the can cover groove 16 is ejected, ensuring that the subsequent iron can pushing and removing process proceeds smoothly.

[0041] Then the second turntable 12 rotates 45° until its can body rack 17 is located directly above the sending push block 95, and the second turntable 12 moves stationary for a period of time. At this time, the can body sending groove 94 is also located directly above the can body rack 17, and the can cover and can body rack 15 leaves the arc baffle 131 so that the can cover and can body rack 15 returns to the initial position. The main rotating shaft 13 rotates to drive the sending pushing block 95 to rise and push the can body into the can body sending groove 94. The electromagnet in the can body sending groove 94 works to place the can body firmly in the can body sending groove 94. Then the main rotating shaft 13 no longer allows the sending pushing block 95 to push up, so that the sending pushing block 95 is away from the can body, and the can body sending groove 94 is pushed to the conveyor belt device 91 by the sending pushing rack 92. The electromagnet of the can body sending groove 94 stops working and stops magnetically attracting the can body, so that the can body falls onto the conveyor belt device 91 and is transported out. The can body sending groove 94 continues to be pushed back by the sending pushing rack 92 to the top of the can body rack 17, completing a working process of the present invention.

[0042] The first turntable 11 and the second turntable 12 of the present invention are respectively provided with 8 workstations, that is, when the present invention is working, each device works simultaneously to form a pipeline-type work process.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
