Description

Technical Field

[0001] The utility model relates to the technical field of capacitor processing, in particular to a blanking device for an aluminum electrolytic capacitor casing machine. Background Art

[0002] During the capacitor production process, a plastic sleeve is placed over the aluminum shell of the capacitor. The sleeve is printed with the capacitor's electrical properties and manufacturer's information. After the sleeve is completed, the fixture clamps the capacitor and unloads it.

[0003] The current unloading device generally uses a robot to first clamp the capacitor, then drive the capacitor upward to separate from the casing machine, and then drive the capacitor to rotate above the conveyor belt. The capacitor is then released and falls onto the conveyor belt. This type of robot is generally more sophisticated and expensive, and the capacitor is easily deformed and damaged when the robot clamps it. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings. Example

[0021] Reference Figures 1 to 3 The present invention discloses a blanking device for an aluminum electrolytic capacitor casing machine. The device comprises a casing machine body, which includes a base 2 and a rotating disk 3 located above the base 2. The rotating disk 3 is driven intermittently by a motor (not shown). The casing machine body casings capacitors, and the completed capacitors are positioned on top of the rotating disk 3. A conveyor belt 4 is provided on one side of the rotating disk 3 to transport the completed capacitors. The above-described prior art is not detailed here.

[0022] The top of the base 2 is rotatably connected to a driven rod 5, which is connected to the rotating disk 3 via a belt transmission. The top of the driven rod 5 is fixedly connected to a top plate 6, so that the top plate 6 moves synchronously with the rotating disk 3.

[0023] The bottom of the top plate 6 is fixedly connected to a plurality of electric push rods 7, and the output ends of two corresponding electric push rods 7 are fixedly connected to a top shell 8. The bottom of the top shell 8 is open. When the rotating plate 3 is stationary, the capacitor completed by one of the sleeves is located directly below the corresponding top shell 8.

[0024] A linkage unit 9 is provided within the top plate 6. This linkage unit 9 comprises several accommodating cavities 91 defined within the top plate 6. These cavities 91 are located directly above the corresponding top shell 8, and pistons 92 are interference-fitted within these cavities. Several communication ports are defined at the top of the top plate 6, connecting to the corresponding cavities 91. The upper half of these cavities 91 is open to the outside world, ensuring that the pistons 92 are not subject to pressure resistance from above during movement.

[0025] A sliding rod 93 is fixedly connected to the bottom of the piston 92. This sliding rod 93 slides through the bottom wall of the accommodating chamber 91 and is fixedly connected to the top of the top shell 8. An exhaust pipe is fixedly inserted into the lower half of the accommodating chamber 91, and a one-way valve 94 is fixedly mounted on the outer periphery of the exhaust pipe. The one-way valve 94 prevents airflow from flowing from the lower half of the accommodating chamber 91 to the outside of the accommodating chamber 91, preventing reverse flow.

[0026] A fixing portion 10 is provided within the top shell 8. The fixing portion 10 comprises an annular cavity 101 formed within the sidewall of the top shell 8. The annular cavity 101 communicates with the lower half of the corresponding accommodating chamber 91 via a flexible tube. Several air intake ports 102 are formed on the inner circumference of the top shell 8 and communicate with the annular cavity 101.

[0027] In the initial state, the top shell 8 is completely located above the capacitor and does not hinder the rotation of the capacitor on the rotating disk 3. The electric push rod 7 moves downward, driving the top shell 8 to move downward, and the upper half of the capacitor is located in the top shell 8. At the same time, the top shell 8 drives the sliding rod 93 and the piston 92 to move downward, and the air below the piston 92 is discharged through the exhaust pipe and the one-way valve 94.

[0028] Then the electric push rod 7 moves upward, driving the top shell 8 to move upward, and the top shell 8 drives the sliding rod 93 and the piston 92 to move upward, and a negative pressure is formed under the piston 92, so a negative pressure is formed at the air intake 102 and the annular cavity 101. When the negative pressure at the air intake 102 is strong enough to stably adsorb the capacitor so that it is relatively stationary with the top shell 8, the upper half of the capacitor has not completely left the top shell 8. Therefore, the electric push rod 7 continues to move upward, which can drive the capacitor to move upward, so that the capacitor is separated from the rotating disk 3 until the top shell 8 moves to the initial height.

[0029] A sealing layer 103 is fixedly connected to the inner wall of the top shell 8, and the air inlet 102 extends through the side wall of the sealing layer 103. The sealing layer 103 is made of rubber material. When the upper half of the capacitor enters the top shell 8, the sealing layer 103 can fully fit the outer wall of the capacitor, thereby fully shielding the air inlet 102 from the outer wall of the capacitor, thereby improving the negative pressure adsorption effect.

[0030] An air inlet 95 is provided on the outer periphery of the top plate 6. The air inlet 95 includes an air inlet port 951 formed on the outer periphery of the top plate 6, which communicates with the accommodating cavity 91. Several springs 952 are fixedly connected to the outer periphery of the top plate 6. The springs 952 are rigid springs that can only expand or contract, but cannot bend.

[0031] The corresponding ends of the springs 952 away from the top plate 6 are commonly fixedly connected to a side plate 953, and one side of the side plate 953 is fixedly connected to a connecting rod 954, which passes through the corresponding air inlet 951, and the end of the connecting rod 954 away from the side plate 953 is fixedly connected to a baffle 955, and the baffle 955 is in contact with the inner wall of the accommodating cavity 91 and completely covers the corresponding air inlet 951.

[0032] A fixing plate 956 is fixedly connected to the top of the base 2. An arc-shaped protrusion 957 is fixedly connected to one side of the fixing plate 956 at a position corresponding to the side plate 953. When the side plate 953 moves to the arc-shaped protrusion 957, the arc-shaped protrusion 957 squeezes the side plate 953, thereby compressing the spring 952 and moving the baffle 955 away from the side plate 953, revealing the corresponding air inlet 951. External air enters the accommodating chamber 91 through the air inlet 951, and the air pressure in the accommodating chamber 91 returns to normal. The capacitor is no longer attracted by the negative pressure and falls directly to the top of the conveyor belt 4 for transportation.

[0033] When the rotating disk 3 is stationary, the corresponding side plate 953 contacts the arc-shaped protrusion 957 and the spring 952 is compressed. During the time when the rotating disk 3 is stationary, the air pressure in the accommodating cavity 91 can return to normal, and the capacitor can fall onto the conveyor belt 4.

[0034] When the side plate 953 continues to rotate away from the arc-shaped protrusion 957, the baffle 955 covers the corresponding air inlet 951 under the restoring force of the spring 952. From the beginning to the end, the negative pressure strength in the accommodating chamber 91 is not enough to compress the spring 952.

[0035] The implementation principle of the above embodiment is:

[0036] The rotating disk 3 and the top disk 6 are stationary, the electric push rod 7 moves downward, driving the top shell 8 to move downward, and the upper half of the capacitor is located in the top shell 8. At the same time, the top shell 8 drives the sliding rod 93 and the piston 92 to move downward, and the air flow below the piston 92 is discharged through the exhaust pipe and the one-way valve 94.

[0037] Then the electric push rod 7 moves upward, the top shell 8, the sliding rod 93 and the piston 92 move upward, and a negative pressure is formed under the piston 92, so a negative pressure is formed at the air intake port 102 and the annular cavity 101. When the negative pressure at the air intake port 102 is large enough, the capacitor is adsorbed by the negative pressure, and the electric push rod 7 continues to move upward, which can drive the capacitor to move upward, so that the capacitor is separated from the rotating disk 3 until the top shell 8 moves to the initial height.

[0038] The motor works to make the rotating disk 3 and the top disk 6 rotate to a certain angle and then stop. The arc-shaped protrusion 957 squeezes the side plate 953, so the spring 952 is compressed, and the baffle 955 moves in the direction away from the side plate 953, and the corresponding air inlet 951 is exposed. The external air enters the accommodating chamber 91 through the air inlet 951, and the air pressure in the accommodating chamber 91 returns to normal. The capacitor is no longer adsorbed by the negative pressure, and the capacitor falls directly to the top of the conveyor belt 4 and is transported.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
