Description

Technical Field

[0001] The utility model relates to the production of aluminum bottle caps, in particular to a feeding mechanical arm for the production of aluminum bottle caps. Background Art

[0002] The production process of aluminum bottle caps includes raw material selection, bottle cap manufacturing, surface treatment and packaging. First of all, the selection of raw materials for aluminum bottle caps is very important. Generally, high-purity aluminum plates are used as the base material of bottle caps because high-purity aluminum has good plasticity, strength and corrosion resistance. Secondly, bottle cap manufacturing is the core link of aluminum bottle cap production. First, after precise cutting and forming processes, the aluminum plates are cut into bottle cap blanks of appropriate sizes. Then, the blanks are stamped into shape by a die punch to obtain the basic shape of the bottle cap.

[0003] In the actual production process, the aluminum discs (bottle cap blanks) formed by preliminary processing are often fed manually or with electrical automation equipment during transportation to the next processing station (mold punching machine). Manual feeding is not efficient.

[0004] The use of electrical automation control to transfer and deliver materials requires multiple action structures to cooperate with each other (including adsorption, lifting, transfer and other actions); each action structure is driven by a power source, and the multiple power sources are coordinated through an industrial control protocol system; there is no direct connection and coordination between multiple execution action structures, but a logical coordination relationship is established by software program control; with the increase of usage time, some components of each execution action structure often age, causing signal transmission delays and action execution component jams, which ultimately leads to reduced coordination accuracy.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] See also Figures 1 to 10 As an embodiment of the utility model, the feeding robot arm for aluminum bottle cap production includes a base 1 and a connecting arm 13 arranged on the base 1, one end of the connecting arm 13 is provided with a connecting plate 17, a plurality of suction cups 18 are installed below the connecting plate 17, and one end of the connecting arm 13 away from the suction cup 18 is connected to a lifting assembly, and the lifting assembly is used to drive the suction cup 18 to move upward and downward through the connecting arm 13;

[0033] The end of the connecting arm 13 away from the suction cup 18 is also connected to a deflection assembly, and the deflection assembly is used to drive the suction cup 18 to deflect through the connecting arm 13;

[0034] The deflection assembly and the lifting assembly are both connected to a driving assembly, and the driving assembly is used to alternately drive the lifting assembly and the deflection assembly to move;

[0035] Among them, when the deflection assembly drives the suction cup 18 to deflect to the end of its stroke, the lifting assembly drives the suction cup 18 to move up and down. When the lifting assembly drives the suction cup 18 to move up and down to the end of its stroke, the deflection assembly drives the suction cup 18 to perform deflection movement.

[0036] In this embodiment, when the connecting arm 13 is at the lowest point of the incoming end of the aluminum disc, the aluminum disc is sucked by the suction cup 18; then the driving component drives the lifting component to move, and lifts the connecting arm 13 to lift the connecting plate 17 and thus lift the suction cup 18. At this time, the sucked aluminum disc is lifted along with the lifting of the suction cup 18, and during the lifting process, the deflection component does not move.

[0037] When the suction cup 18 reaches the highest point of the aluminum disc, the driving component stops driving the lifting component and turns to drive the deflection component. Driven by the deflection component, the connecting arm 13 starts to deflect, thereby driving the suction cup 18 on the connecting plate 17 to deflect, and the sucked aluminum disc also deflects accordingly. When the connecting arm 13 reaches the end of the deflection stroke driven by the deflection component (that is, directly above the aluminum disc stamping and forming processing position), the driving component stops driving the deflection component and completes the transfer of the aluminum disc from the incoming material station to the processing station.

[0038] At the same time, the driving assembly rotates to drive the lifting assembly. Driven by the action of the lifting assembly, the connecting arm 13 drops to the lowest point, and the suction cup 18 also drops to the lowest point, releasing the aluminum disc and causing it to fall into the processing position.

[0039] After the aluminum disc is separated from the suction cup 18, the lifting assembly starts to lift the suction cup by lifting the connecting arm 13, so that the suction cup 18 is lifted to its highest point. At this time, the driving assembly drives the deflection assembly to reversely deflect to the initial position (the highest point of the incoming material station), and finally the lifting assembly drives the connecting arm 13 to reset the suction cup 18 to the lowest point of the incoming material station, thus completing a complete aluminum disc transfer action.

[0040] As a further solution of the utility model, the driving assembly includes a motor 2 fixedly mounted on the base 1; the output end of the motor 2 is fixedly connected to a transmission shaft 3, and the transmission shaft 3 is rotatably mounted on the base 1;

[0041] A half gear 4 is fixedly mounted on the transmission shaft 3, and a full gear 5 is rotatably mounted on the base 1. The full gear 5 cooperates with the half gear 4. When the full gear 5 and the half gear 4 are meshed with each other, the driving assembly drives the deflection assembly to move. When the full gear 5 and the half gear 4 are disengaged, the driving assembly drives the lifting assembly to move.

[0042] In this embodiment, the size of the half gear 4 is consistent with that of the full gear 5, and the number of teeth of the half gear 4 is half of that of the full gear 5. When the motor 2 starts to work, it drives the transmission shaft 3 to rotate, thereby driving the half gear 4 to rotate. When the half gear 4 is meshed with the full gear 5, the driving assembly only serves as the power source of the yaw assembly. When the half gear 4 is disengaged from the full gear 5, the driving assembly only serves as the power source of the lifting assembly.

[0043] By changing the connection state between the half gear 4 and the full gear 5, the driving assembly drives the lifting assembly and the deflection assembly to move alternately.

[0044] A drive component realizes the alternating coordination between multiple functional components through mechanical transmission, and avoids the problem of low coordination accuracy caused by signal transmission delay, jamming of moving parts, etc. when coordinating the coordination between multiple drive components through the industrial control host using logic programs, thereby reducing the risk of disordered coordination between components when the equipment is running.

[0045] As a further solution of the utility model, the deflection assembly includes a cam 6 fixedly connected to the full gear 5; it also includes a connecting rod 7, on which a slot 701 is provided, and the slot 701 and the protruding block fixed on the cam 6 are slidably matched with each other, and the connecting rod 7 in the deflection assembly is connected to the connecting arm 13.

[0046] In this embodiment, when the driving assembly serves as the power source of the deflection assembly, the full gear 5 starts to rotate, thereby driving the cam 6 to rotate. Through the sliding cooperation between the protruding block fixed on the cam 6 and the slot 701, the connecting rod 7 deflects back and forth with the rotation of the cam 6, driving the connecting arm 13 to deflect back and forth with the rotation of the cam 6. Finally, the suction cup 18 also realizes a reciprocating deflection motion with the rotation of the cam 6, completing the conversion of the aluminum disc from the incoming position to the processing position or from the processing position to the incoming position.

[0047] As a further solution of the utility model, the lifting assembly includes a guide groove 301 provided on the transmission shaft 3 and a lifting block 10 rotatably installed on the transmission shaft 3, and the lifting block 10 can only be raised and lowered above the base 1; a circular groove 1001 is provided on the lifting block 10, and a guide column 11 is installed on the circular groove 1001, and the guide column 11 and the guide groove 301 are slidably matched with each other.

[0048] In this embodiment, the guide groove 301 is divided into two parts, a V-section and a straight section. The V-section and the straight section each occupy half of the circumference of the transmission shaft 3. When the half gear 4 is meshed with the full gear 5, the transmission shaft 3 drives the guide groove 301 to rotate. At this time, the guide column 11 only slides in the straight section of the guide groove 301. In this state, the driving component only serves as a power source for the yaw component.

[0049] At the moment when the half gear 4 is disengaged from the full gear 5, the guide column 11 reaches the end point of the V-field on the guide groove 301, and then the transmission shaft 3 drives the guide groove 301 to rotate. At this time, the guide column 11 only slides in the V-field of the guide groove 301, and the inner wall of the guide groove 301 will squeeze the guide column 11, so that the guide column 11 rises and falls under the guidance of the V-field, and finally drives the lifting block 10 to slide up and down. At the moment when the half gear 4 is re-engaged with the full gear 5, the guide column 11 reaches the other end point of the V-field on the guide groove 301. In this state, the driving component serves as the power source of the lifting component.

[0050] The provision of the circular groove 1001 facilitates the installation of the guide post 11 and also makes subsequent maintenance more convenient.

[0051] As a further solution of the utility model, the lifting assembly further comprises a rotating shaft sleeve 8 rotatably mounted on the base 1, the rotating shaft sleeve 8 is fixedly connected to the connecting rod 7; an inner groove 801 is formed on the rotating shaft sleeve 8;

[0052] The lifting assembly also includes a rotating shaft 9, on which a boss 901 is fixedly provided, the boss 901 and the inner groove 801 are slidably fitted with each other, and the rotating shaft 9 is fixedly installed on the connecting arm 13; a lifting rod 12 is rotatably connected to the rotating shaft 9, the lifting rod 12 is fixedly installed on the lifting block 10, and the lifting rod 12 is in conflict with the guide column 11; the rotating shaft 9 in the lifting assembly is connected to the connecting arm 13.

[0053] In this embodiment, when the half gear 4 is meshed with the full gear 5, the connecting rod 7 will drive the rotating shaft sleeve 8 to rotate on the base 1, and drive the rotating shaft 9 to rotate under the interlocking action of the inner groove 801 and the boss 901, so that the connecting arm 13 also performs a yaw movement with the movement of the yaw assembly. When the half gear 4 is disengaged from the full gear 5, the lifting block 10 will drive the lifting rod 12 fixedly connected thereto to move upward or downward, thereby driving the rotating shaft 9 to slide up and down in the rotating shaft sleeve 8, so that the connecting arm 13 also performs an upward and downward movement.

[0054] As a further solution of the utility model, the connecting arm 13 is connected to the connecting plate 17 through a buffer assembly, and the buffer assembly includes a sleeve 14 fixedly mounted on the connecting arm 13, and a sleeve column 16 is slidably connected to the sleeve 14, and the sleeve column 16 is engaged with the sleeve 14; a spring 15 is provided in the sleeve 14, and the two ends of the spring 15 are respectively in contact with the connecting arm 13 and the sleeve column 16.

[0055] In this embodiment, when the suction cup 18 contacts the aluminum disc, since the height of the aluminum disc pile cannot be accurately controlled, when the height of the aluminum disc is greater than the lowest point height of the downward movement of the suction cup 18, the aluminum disc will squeeze the suction cup 18, and the air in the suction cup 18 will be squeezed out. At this time, negative pressure is formed between the suction cup 18 and the aluminum disc, so that the aluminum disc is firmly adsorbed.

[0056] If the aluminum disc is still squeezed by the suction cup 18 after being adsorbed, the squeezing force will be transmitted to the sleeve column 16 along the connecting plate 17, causing the sleeve column 16 to slide inward in the sleeve 14 and compress the spring 15 that conflicts with it. The elastic force of the spring 15 offsets this squeezing force, thereby preventing the aluminum disc from being too high and exceeding the lowest point height of the suction cup 18 when it moves downward, thereby preventing the excessive squeezing force from damaging the equipment or squeezing and deforming the aluminum disc itself.

[0057] As a further solution of the utility model, a protective cover 19 is fixedly mounted on the base 1 , a slide groove 1901 is opened on the protective cover 19 , and the connecting arm 13 passes through the slide groove 1901 to be connected with the buffer assembly and the rotating shaft 9 .

[0058] In this embodiment, the protective cover 19 can prevent the components installed therein from being damaged by external forces during the actual production process. The opening of the slide groove 1901 provides space for the movement of the connecting arm 13, and the slide groove 1901 can play a dual role of guiding and supporting the movement of the connecting arm 13.

[0059] As a further solution of the utility model, a position sensor is installed on the connecting plate 17, and a solenoid valve is installed on 18, and the position sensor cooperates with the solenoid valve.

[0060] In this embodiment, the solenoid valve opens only after the position sensor sends a signal, and the position sensor sends a signal only when the suction cup 18 reaches the lowest point of the processing position. When the suction cup 18 reaches the lowest point of the processing position, the position sensor on the connecting plate 17 sends a signal to the solenoid valve on the suction cup 18, causing the solenoid valve to open, thereby releasing the negative pressure between the suction cup 18 and the aluminum disc and releasing the aluminum disc to the processing position.

[0061] The above embodiments are exemplary rather than restrictive, so without departing from the spirit or basic features of the present invention, the technical solutions of the present invention that can be implemented in other specific forms are all included in the present invention.
