Description

Technical Field

[0001] The utility model relates to an aluminum foil taking, placing and stacking device for aluminum capacitors, belonging to the technical field of aluminum capacitor production equipment. Background Art

[0002] During the aluminum capacitor production process, it is sometimes necessary to transfer aluminum foil from one location to another and stack it.

[0003] For example, Chinese patent publication CN209226207U discloses an aluminum foil stacking device comprising a conveyor belt, a rotating arm assembly, and a stacking platform. The conveyor belt is connected to a cylinder, the output end of which is connected to a push plate, which is connected to a push plate guide rail located directly above the conveyor belt. The rotating arm assembly comprises a rotating arm, a bracket, a suction plate, a rotating arm motor, and a lifting motor. One end of the rotating arm is connected to the suction plate, and the other end is connected to the power output end of the rotating arm motor. The rotating arm motor is fixed to a sliding bracket, which is connected to the bracket via a sliding assembly. The sliding assembly comprises a lead screw, bracket guide rollers, and sliders connected to both sides of the sliding bracket. The sliders are connected to the bracket guide rollers, and the lifting motor is connected to the lead screw to drive the sliding bracket up and down. The suction plate is equipped with several pneumatic suction cups, and both the pneumatic suction cups and the cylinder are connected to an air source. This device can stack the aluminum foil cut from the conveyor belt together, preventing deformation and bending of the foil by airflow.

[0004] The process of the arm assembly in the equipment completing an aluminum foil stacking cycle is as follows: the arm moves down and the pneumatic suction cup sucks the aluminum foil, the arm moves up, the arm rotates forward, the arm moves down to place the aluminum foil on the stacking table, the arm moves up, and the arm rotates in the opposite direction to reset. Among them, the arm moves up and rotates forward after the pneumatic suction cup sucks the aluminum foil can be completed simultaneously, and the arm moves up and rotates in the opposite direction to reset after the aluminum foil is placed on the stacking table can be completed simultaneously. It can be seen that the arm assembly needs to perform at least four actions arranged in chronological order to complete an aluminum foil stacking cycle, resulting in low efficiency of the equipment in stacking aluminum foil.

If arranged in chronological order, the present invention only requires three actions to complete an aluminum foil stacking cycle: Step 1: The actuator 5 absorbs the aluminum foil, and the lifting drive assembly 4 drives the actuator 5 to rise to the maximum position, while the rotary drive assembly 3 drives the actuator 5 to swing a certain angle; Step 2: The lifting drive assembly 4 drives the actuator 5 down to a suitable position, and the actuator 5 releases the aluminum foil; Step 3: The lifting drive assembly 4 first drives the actuator 5 up to the highest position, and then drives the actuator 5 down to a height position where it can absorb the aluminum foil, while the rotary drive assembly 3 drives the actuator 5 to swing in the opposite direction a certain angle to reset to the initial position. It can be seen that the present invention only requires three actions to complete an aluminum foil stacking cycle when arranged in chronological order, which speeds up the aluminum foil stacking speed and improves the aluminum foil stacking efficiency.

[0032] The lifting drive assembly 4 includes a lifting drive motor 41, a coupling 42, and a drive shaft 43. The lifting drive motor 41 is mounted on the side wall of the main frame 1. One end of the coupling 42 is connected to the output shaft of the lifting drive motor 41, the middle portion is rotatably connected to the side wall of the main frame 1, and the other end extends into the main frame 1. One end of the drive shaft 43 extends into the rotation drive assembly 3, and the other end is connected to the end of the coupling 42 away from the lifting drive motor 41.

During use, the middle portion of the coupling 42 is connected to the side wall of the main frame 1 via a deep groove ball bearing; one end of the drive shaft 43 extends into the transmission frame 32.

[0033] The lifting drive motor 41 is a servo motor or a stepping motor.

[0034] The driving shaft 43 is fitted with a bearing 44, which maintains contact with the actuator 5. During operation, the bearing 44 contacts the shoulder surface of the abutment block 51. Under the action of the compression spring B553, the transmission shaft 52 tends to slide downward, allowing the bearing 44 to maintain contact with the shoulder surface of the abutment block 51. During operation, the driving shaft 43 and bearing 44 are assembled to form a standard follower, which is readily available on the market.

[0035] The actuator 5 is L-shaped and includes a transmission shaft 52 and a swing arm 54. One end of the swing arm 54 is provided with an aluminum foil picking and placing component 55, and the other end is connected to one end of the transmission shaft 52. The middle part of the transmission shaft 52 passes through the base 2 and is movably connected to the base 2. A compression spring A53 is installed on the transmission shaft 52 between the swing arm 54 and the base 2, and a supporting block 51 is provided on the end of the transmission shaft 52 away from the swing arm 54.

[0036] The longitudinal section of the abutting block 51 is in the shape of an inverted convex letter.

[0037] The aluminum foil taking and placing component 55 includes a detection signal block A551, a detection signal block B554, and a negative pressure suction nozzle 555. The detection signal block A551 is installed at the bottom of the swing arm 54 through a connecting assembly.

The detection signal block B554 contacts the detection signal block A551 under the push of the compression spring B553. The negative pressure suction nozzle 555 is provided on the detection signal block B554.

[0038] The connecting assembly includes a T-shaped insulating sleeve 558, an insulating gasket 552 and a locking screw. A T-shaped stepped hole is provided on the detection signal block A551 along the thickness direction, and the large end of the T-shaped stepped hole faces downward. The T-shaped insulating sleeve 558 is located in the T-shaped stepped hole on the detection signal block A551. A countersunk hole is provided on the T-shaped insulating sleeve 558, and the large end of the countersunk hole faces downward. The insulating gasket 552 is located between the detection signal block A551 and the swing arm 54. One end of the locking screw passes through the countersunk hole on the T-shaped insulating sleeve 558 and the inner hole of the insulating gasket 552 and is threadedly connected to the threaded hole at the bottom of the swing arm 54.

[0039] During use, the swing arm 54 is provided with a micro-slider 556, and the detection signal block B554 is provided with a micro-guide rail 557. The micro-guide rail 557 and the micro-slider 556 are slidably connected, thereby achieving a sliding connection between the detection signal block B554 and the swing arm 54. The T-shaped insulating sleeve 558 is used to separate the detection signal block A551 from the locking screw (not shown), thereby maintaining insulation between the detection signal block A551 and the locking screw; the insulating gasket 552 is used to separate the detection signal block A551 from the swing arm 54, thereby maintaining insulation between the detection signal block A551 and the swing arm 54.

[0040] As more and more aluminum foil is stacked together, the height of the aluminum foil pile increases. The downward travel of the actuator 5 to release the aluminum foil needs to be gradually reduced. However, the aluminum foil used in aluminum capacitors is relatively fragile. If the pressure exerted on the aluminum foil pile by the actuator 5 during downward movement is too great, the aluminum foil can easily be crushed. Therefore, the detection signal block A551 and the detection signal block B554 are used in conjunction to achieve the purpose of controlling the downward travel of the negative pressure suction nozzle 555 when releasing the aluminum foil. On the one hand, this adapts to the increasing height of the aluminum foil pile, and on the other hand, it prevents the negative pressure suction nozzle 555 from exerting too much pressure on the aluminum foil, which could cause the aluminum foil to be crushed.

[0041] The working principle or use process of the aluminum foil picking, placing and stacking device for aluminum capacitors described in the utility model is as follows:

[0042] The first step is to start from the initial position. When the negative pressure nozzle 555 sucks the aluminum foil, the lifting drive motor 41 is activated, and the driving shaft 43 is driven to rotate through the coupling 42. The bearing 44 on the driving shaft 43 pushes the abutment block 51 upward. The abutment block 51 drives the transmission shaft 52 and the swing arm 54 to overcome the spring force of the compression spring A53 and move upward to the highest position. The compression spring A53 is further compressed. At the same time as the lifting drive motor 41 is activated, the rotation drive motor 31 is activated, driving the transmission frame 32 to rotate. The transmission frame 32 transmits the torque to the transmission shaft 52 through the ball spline pair. The transmission shaft 52 drives the swing arm 54 to swing a certain angle.

[0043] In the second step, the lifting drive motor 41 moves again, driving the coupling 42 and the driving shaft 43 to rotate a certain angle, the compression spring A53 is extended, and the swing arm 54 and the transmission shaft 52 are pushed down together. When the aluminum foil sucked by the negative pressure suction nozzle 555 contacts the aluminum foil pile, the aluminum foil reacts to the negative pressure suction nozzle 555, and the negative pressure suction nozzle 555 pushes the detection signal block B554 to overcome the force of the compression spring B553 and move upward. The detection signal block B554 is separated from the detection signal block A551, and the conduction signal is disconnected. The lifting drive motor 41 stops driving the negative pressure suction nozzle 555 to continue moving down to crush the aluminum foil, and the negative pressure suction nozzle 555 releases the aluminum foil.

[0044] In the third step, the lifting drive motor 41 is activated to drive the negative pressure suction nozzle 555 to move up and then down to the initial height position. During this process, the rotation drive motor 31 is activated to drive the transmission shaft 52 to drive the swing arm 54 to swing in the opposite direction and reset to the initial position; when the negative pressure suction nozzle 555 is separated from the aluminum foil, the compression spring B553 extends and pushes the detection signal block B554 to move down and reset, and the detection signal block B554 contacts the detection signal block A551 again, and the conduction signal is connected.
