Technical Field

[0001] This invention relates to a needle-threading device for a rotating shaft between a can lid and a can body in the field of automated mechanical assembly. Background Technology

[0002] Common tin cans used for storing candy typically feature a lid. To facilitate opening and closing the can after use, the lid is usually fitted with a hinged structure, connected to the can body by a sturdy hinge. Users can easily open the lid from the opening in the can and close it securely afterward. However, the small size of tin cans and the small hinge between the lid and body make it difficult for assembly workers to thread the thin hinge between the lid and body during manufacturing. Summary of the Invention

[0003] This invention utilizes the rotation of the main rotating shaft to drive the rotation of the first and second turntables, as well as the movement of components within the motor drive devices of each unit.

[0006] The initial position of the can lid and can body frame is such that, under the influence of rebound devices on both sides of the movable can lid table, a certain gap is reserved between the movable can lid table and the can body frame as well as between the movable can lid table and the frame push plate, a spring plunger pushes the can lid groove outward, so that the can lid groove slightly rotates counterclockwise, at this time, the left swinging post on the can lid groove is located at the upper end of the swinging post inclined groove, and the right swinging post is located at the lower end of the swinging post inclined groove. Wherein, the inner blocking surface of the arc-shaped baffle can tightly push against the frame push plate, and the inner blocking surface of the arc-shaped baffle located below the second pin-penetrating device is indented inward, thereby further pushing the frame push plate inward to make the can lid groove on the can lid and can body frame cling to the can body frame.

[0007] Wherein, the can lid groove twisting frame on the first pin-penetrating device is in a shape of "凵", and the transverse opening of the can lid groove twisting frame is slightly inclined to the hole direction of the can body shaft pin hole, the bottom surface of the can lid groove twisting frame is an arc edge, so that when the can lid groove twisting frame presses down, it can press the can lid groove to twist to a certain inclination angle, thereby making the can lid installed on the can lid groove swing to a certain angle, so that one end of the can lid shaft pin hole opened on the can lid directly clings to the can body shaft pin hole opened on the can body, ensuring that the shaft pin is successfully assembled into the can body shaft pin hole. A can lid vibration plate is installed beside the can lid conveying groove, the can lid is actively pushed into the can lid conveying groove through the can lid vibration plate, thereby providing a force for pushing the can lid placed in the can lid conveying groove toward the pushing groove plate.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Reference Figures 1-13The automatic can body and can lid assembly machine of the present invention includes a first turntable 11, a second turntable 12, and a main rotating shaft 13. The first turntable 11 and the second turntable 12 operate synchronously, with the first turntable 11 located to the side of the second turntable 12. The main rotating shaft 13 is connected to pulleys of the first turntable 11 and the second turntable 12 respectively. A can lid feeding device 2 and a can lid needle-threading device 3 are arranged sequentially around the rotation direction of the first turntable 11. 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 sequentially around the rotation direction of the second turntable 12. The automatic can body and can lid assembly machine of the present invention is equipped with a main rotating shaft motor to drive the main rotating shaft 13 to rotate, thereby driving the first turntable 11 and the second turntable 12 to rotate counterclockwise synchronously. Through the longitudinal rotating shaft 132, the rotating frame push plate 54, the can lid unloading push rod 95, and the delivery push block 95 mounted on the push frame plate 131 are driven to move up and down. The rotary 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. A switching box pulley is mounted on the switching box input shaft, and either the first rotary box 11 or the second rotary box 12 is mounted on the switching box output shaft. A motion mechanism is installed between the switching box input shaft and the switching box output shaft, enabling the switching box output shaft to perform intermittent motion. This allows the continuous motion transmitted from the drive shaft 13 to the switching box input shaft to be switched to intermittent motion, causing the first rotary box 11 and the second rotary box 12 to rotate intermittently in a horizontal direction via the switching box output shaft. The rotation pattern of the first rotary box 11 and the second rotary box 12 is as follows: after rotating to 45°, it remains stationary for a period of time, then rotates another 45°, and remains stationary for another period of time. During the time the first rotary box 11 and the second rotary box 12 remain stationary, the can lid feeding device 2, the first needle-threading device 7, and other devices complete one cycle of their respective work processes. A tank body conveyor belt is installed on the side of the tank body feeding device 5, and the tank body conveyor belt is directly opposite the tank body push groove of the tank body pusher 52.

[0034] In operation, workers place multiple cans on the can body conveyor belt, with the can body shaft pinholes facing towards the second turntable 12. A can cover vibrating plate on the can cover conveying trough 21 transports the can covers in an orderly manner into the can cover feeding trough 21, with the can cover shaft pinholes facing away from the first turntable 11. The main rotating shaft 13 rotates, driving the first turntable 11 and the second turntable 12 to rotate. The can cover conveying trough 21 on the can cover feeding device 2 transports the can covers, and the can cover conveying baffle 22 rises, no longer obstructing the can cover transport, allowing the can covers to be transported onto the pushing trough plate 23. After the pushing trough plate 23 is filled with can covers, the can cover conveying baffle 22 descends to block new can cover pushes. The trough plate pusher device 24 pushes the pushing trough plate 23 forward to below the can cover transport device 14. The vertical moving pusher 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 extracted, thereby tightening the can cover. The can lid is tightly adsorbed. The vertical moving pusher 142 rises, and the horizontal moving guide rail slider device 141 moves forward to place the adsorbed can lid directly above the can lid groove 111 on the first turntable 11. The vertical moving pusher 142 descends until the adsorbed can lid is placed in the can lid groove 111. Air is injected into the inside of the suction cup 143 to release the adsorption effect on the can lid. The vertical moving pusher 142 rises, and the horizontal moving guide rail slider device 141 moves backward until the suction cup 143 on the vertical moving pusher 142 is placed directly above the push trough plate 23. The trough plate pusher device 24 pulls the push trough plate 23 back to the side of the can lid conveying trough 21.

[0035] Then the first turntable 11 rotates 45°, stops, rotates 45° again, stops, rotates 45° again, stops, rotates 45° again, stops, and rotates 45° again until the can lid groove 111 containing the can lid is placed next to the can lid needle threading device 3. The needle on the needle conveying device 36 is pushed into the needle hole holder 39. The longitudinal movable plate push rod pushes the longitudinal movable plate 38 forward, pushing the needle hole holder 39 containing the needle forward until the needle is directly above the needle clamping base. The lateral movable plate push rod pushes the lateral movable plate push rod. The moving plate 37 moves the pin hole holder 39 away from the pin clamping base, while the sliding rod pusher device controls the sliding rod 35 to rise and clamp the pin to the bottom of the clamping rod 34; the can lid needle threading device motor rotates, and the clamping rod cam 321 pushes the clamping rod 34, causing the clamping rod 34 to swing in the direction of its lower end toward the can lid. At the same time, the clamping bracket cam 323 rotates and pushes the pin hole clamping bracket 311 down to clamp the pin hole clamp onto the can lid pin hole. The clamping rod 34, which holds the pin, swings until the pin is fully aligned with the can lid pin hole. To the can lid shaft hole; the side pusher 322 pushes the rocker arm protrusion 341, causing the clamping rod rocker arm 33 to move laterally, so that the clamping rod 34 inserts the clamped shaft pin into the can lid shaft hole; then the slide rod pusher device controls the sliding rod 35 to descend, so as to release the clamping effect on the shaft pin, while the side pusher 322 continues to rotate, disengaging from the pusher of the rocker arm protrusion, and under the action of the spring mechanism, pushes the clamping rod rocker arm 33 back, so that the clamping rod 34 and the sliding rod 35 are completely disengaged from the shaft pin; the clamping rod cam 321 Continue rotating, no longer pushing the clamping rod 34. Since the weight of the upper end of the clamping rod 34 and the sliding rod 35 is less than the weight of the lower end, the clamping rod 34 swings back to contact the clamping rod cam 321 again, resetting. The support cam 323 continues to rotate to release the downward pushing effect on the shaft hole support cam 311. Under the action of the springback device, the shaft hole support cam 311 rises and resets. After the worker takes out the assembled can cover, one operation of the can cover feeding device 2 is completed.

[0036] The conveyor belt on the can body conveyor pushes the can body into the can body push slot of the can body pusher 52. Then, the can body pusher 52 pushes forward, pushing the can body into the can body rotating frame. Small magnets installed on the can body rotating frame hold the can body tightly. At the same time, the can body feed baffle on the can body pusher 52 moves onto the can body conveyor belt to prevent cans that have not yet been transported into the can body push slot from moving. Then, the can body rotating plate 53 rotates 180° until the can body rotating frame with the can body is directly below the can body frame 17 on the second turntable 12. The main rotating shaft 13 rotates, driving the rotating frame pusher plate 54 to push upward, pushing the can body into the can body frame 17. Then, the rotating frame pusher plate 54 descends to reset. At this time, the can body is held by the small magnets installed on the can body frame 17.

[0037] Then the first turntable 11 rotates 45°, stops, and then rotates 45° again. At the same time, the second turntable 12 rotates 45°, stops, and then rotates 45° again. The rotation of the second turntable 12 pushes the can lid and can body frame 15 into the arc baffle 131. The arc baffle 131 pushes the frame push plate 19 inward by pushing the push plate roller 191, thereby pushing the can lid slot 16 inward to a position where the can lid transport device 14 can put the transported can lid into the can lid slot 16, and there is a certain amount of room for movement between the can lid slot 16 and the can body frame 17. At this time, the can lid groove 111 with the can lid containing the pin and the can lid body frame 15 with the can body are both placed at the can lid transport device 14 between the first turntable 11 and the second turntable 12. The vertical moving pusher 142 descends until the suction cup 143 contacts the can lid with the pin on the can lid groove 111. The air inside the suction cup 143 is extracted, thereby tightly adsorbing the can lid. The vertical moving pusher 142 rises, and the horizontal moving guide rail slider device 141 moves to place the adsorbed can lid directly above the can lid groove 16 of the can lid body frame 15 on the second turntable 12. The vertical moving pusher 142 descends until the adsorbed can lid is placed in the can lid groove 16. Air is injected into the inside of the suction cup 143 to release the adsorption effect on the can lid. The vertical moving pusher 142 rises, and the horizontal moving guide rail slider device 141 moves to place the suction cup 143 on the vertical moving pusher 142 directly above the can lid groove 111 on the first turntable 11.

[0038] Then, the second turntable 12 rotates 45°, and the can lid and can body frame 15, which contains the can body and the can lid with the pin, is placed below the first needle insertion device 7. First, the first rotating shaft 77 rotates, driving each cam to rotate. The rod cam 773 pushes the first rod 72 down, causing the can lid slot screwing frame 75 to press against the can lid slot 16 and rotate the can lid slot 16 by a certain angle, so that the can lid pin hole is aligned with the can body pin hole, and the pin installed on the can lid pin hole is facing the striking pin 76. Then, as the first rod 72 descends, the insertion rod cam 772 first swings the limiting insertion rod 74 forward, and then releases the clamping force on the limiting insertion rod 74. Under the action of the spring-loaded device, the limiting insertion rod 74 returns to its original position, so that the limiting insertion rod 74 can bypass the inward rolled edge and be inserted into the can body if the can body has an inward rolled edge. At this time, the side of the limiting insertion rod 74 is facing the opening of the can body pin hole to limit the deepest insertion distance of the pin. Next, when the first rod 72 descends to its lowest point and one side of the limiting rod 74 is aligned with the can body pin hole, the push rod cam 771 pushes the lower end of the first push rod 73 to swing to the left, releasing the clamping force on the first push rod 73, allowing it to swing back naturally and strike the striking pin limiting cap of the striking pin 76. The striking pin 76 then strikes the pin and moves towards the can body pin hole, finally stopping on the limiting rod 74. Finally, the rod cam 773 releases the clamping force on the first rod 72, and the first rod 72 rises under the action of the spring mechanism; simultaneously, the insert rod cam 772 pushes the limiting rod 74 forward, causing the first rod 72 to lift the limiting rod 74, the first push rod 73, and the can lid slot screwing bracket 75. At this point, the can lid and the can body are connected as a whole by the pin. Furthermore, the can body is no longer attracted by the magnet on the can body frame.

[0039] Then the second turntable 12 rotates 45° until the can lid and can body frame 15 is positioned below the second needle-threading device 8. The second rotating shaft 83 on the second needle-threading device 8 rotates, driving the impact block cam 831, the insertion rod cam 832, and the rod holder cam 833 to rotate, thereby driving the second rod holder 82, the impact block 85, and the insertion rod 86 to move. The rod holder cam 833 drives the second rod holder 82 to descend, causing the various components mounted on the second rod holder 82 to descend. During this descent, the impact block cam 831 drives the impact block 85 to swing outward first and then inward back to its original position, thus... The impact plate 87 can be placed inside the can opening by bypassing the inward rolled edge of the can body. At this time, the impact block on the impact plate 87 is located outside the right end of the shaft pin, ready to push the shaft pin. The impact rod 85 swings inward, causing the can body top groove 851 on the impact rod 85 to hit the shaft pin hole on the can body and push the can body and can cover together to the can cover top bracket 84. The top bracket groove on the can cover top bracket 84 is then pressed tightly against the can cover shaft pin hole. That is, the impact rod 85 and the can cover top bracket 84 form a clamp. The substructure clamps the can cover pin hole and the can body pin hole together, aligning the left opening of the can cover pin hole with the left opening of the can body pin hole to ensure that the pin can pass smoothly into the can body pin hole during operation. Then, the insert rod cam 832 inserts the inclined insert rod 86 into the inclined surface of the impact plate 87 between the impact plate 87 and the impact rod 85, thereby driving the impact plate 87 to move to the left, so that the impact block directly pushes the pin to the left to strike the designated assembly position. Finally, as the second rotating shaft 83 rotates, it drives each cam to rotate, relieving the force acting on the second rod 82, the impact rod 85, and the insertion rod 86. Under the action of each spring device, the second rod 82 rises, driving the impact rod 85, the insertion rod 86, and the impact plate 87 to rise. At this time, the impact rod 85 drives the impact plate 87 to swing upward so that it can smoothly rise around the inner rolled edge of the can body and can mouth. The insertion rod 86 makes an upward swinging motion relative to the impact rod 85, so that the impact plate 87 returns to its original position.

[0040] Then the second turntable 12 rotates 45° until its can body frame 17 is directly above the can lid removal push rod 95. The main rotating shaft 13 rotates to drive the can lid removal push rod 95 to push upward, passing through the can lid removal hole on the can lid groove 16, the can lid platform, and the can lid movable platform 18, and pushing out the can lid that has been combined with the can body and is still placed in the can lid groove 16, ensuring that the subsequent iron can pushing and removal process is carried out smoothly.

[0041] Then the second turntable 12 rotates 45° until its can body frame 17 is directly above the delivery push block 95. The second turntable 12 remains stationary for a period of time. At this time, the can body delivery groove 94 is also directly above the can body frame 17, and the can lid and can body frame 15 leave the arc baffle 131, causing the can lid and can body frame 15 to return to the initial position. The main rotating shaft 13 rotates, driving the delivery pusher 95 to rise and push the can body into the can body delivery groove 94. The electromagnet in the can body delivery groove 94 works, firmly placing the can body in the can body delivery groove 94. Then, the main rotating shaft 13 stops pushing the delivery pusher 95 upward, causing the delivery pusher 95 to move away from the can body. The can body delivery groove 94 is pushed onto the conveyor belt device 91 by the delivery pusher 92. The electromagnet in the can body delivery groove 94 stops working and stops magnetically attracting the can body, causing the can body to fall onto the conveyor belt device 91 and be transported out. The can body delivery groove 94 is then pushed back to the top of the can body frame 17 by the delivery pusher 92, completing one cycle of the workflow of this invention.

[0042] The first turntable 11 and the second turntable 12 of the present invention are each provided with 8 workstations, that is, when the present invention is working, each device works at the same time to form an assembly line-style workflow.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
