Description

Technical Field

[0001] This utility model relates to a turntable for an aluminum electrolytic capacitor assembly machine, belonging to the technical field of aluminum electrolytic capacitor production equipment. Background Technology

[0002] The production of aluminum electrolytic capacitors involves cutting, winding, impregnation, and aging. Electrolytic paper and aluminum foil, which have absorbed the electrolyte, are wound together to form a core package. Leads extend from the core package and are riveted to an outer cover plate. Finally, an aluminum casing is added to complete the assembly of the bare capacitor. A plastic film is placed at the bottom of the aluminum casing, and the capacitor core is placed on the plastic film. The aluminum casing is then tightened to secure the plastic film and the core package.

[0003] When assembling core packs and diaphragms on the assembly machine turntable, the plastic diaphragm must first be fixed in place using clamping components on the turntable. Then, the guide pins of the core pack are inserted into the guide pin holes of the plastic diaphragm to assemble the capacitor assembly. Because unexpected situations such as reversed plastic diaphragm installation, missing core packs, or incorrect guide pin insertion may occur, problematic assembled core packs need to be automatically removed from the turntable to prevent them from entering the next process and mixing with normal products. Existing assembly machines generally use an air nozzle above the core pack station on the turntable to blow problematic core packs off the turntable using compressed air. However, this method is generally only suitable for small-sized capacitors and is ineffective for larger capacitors.

[0004] Therefore, there is a need for a turntable for assembling aluminum electrolytic capacitors, which can clamp, fix and assemble capacitor components while also easily and quickly detaching them from the turntable, thus meeting the needs of automated production of aluminum electrolytic capacitors. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a turntable for assembling aluminum electrolytic capacitors. While clamping, fixing and assembling the capacitor components, it can also easily and quickly detach the capacitor components from the turntable, promptly remove defective products, and meet the needs of automated production of aluminum electrolytic capacitors.

[0006] The purpose of this utility model is achieved as follows:

[0007] A turntable for assembling aluminum electrolytic capacitors includes a circular turntable and a plurality of receiving seats evenly arranged on the outer circumference of the turntable. Each receiving seat includes a support base connected to the turntable, a limiting seat arranged on the support base, and a clamping rod movably arranged next to the limiting seat. The support base is provided with a receiving groove for accommodating guide pins, and the limiting seat is provided with a semi-cylindrical limiting groove.

[0008] A push rod is installed above the receiving seat via a lifting mechanism, and the push rod swings back and forth like a pendulum via a swinging mechanism; the swinging mechanism is mounted on the lifting mechanism.

[0009] The limiting seat is provided with a guide groove for accommodating the bottom end of the push rod, and the guide groove is connected to the limiting groove. After the push rod descends, the lower end of the push rod enters the guide groove. The push rod controls the lower end of the push rod to slide along the guide groove into the limiting groove through the pendulum motion, thereby pushing the capacitor assembly clamped in the receiving seat to disengage from the receiving seat and preventing it from entering the next process.

[0010] Furthermore, the lifting mechanism includes a bracket, and the push rod is mounted on the bracket and is pushed by a lifting cylinder to perform lifting action.

[0011] Furthermore, the swing mechanism includes a rotating shaft rotatably mounted on the bracket, a push rod vertically mounted at one end of the rotating shaft, and a swing arm mounted at the other end of the rotating shaft; the free end of the swing arm is tensioned by a swing spring, and the middle part is pushed upward by a swing cylinder, thereby driving the push rod to perform a pendulum motion.

[0012] Furthermore, the lower end of the push rod has a flat structure, and its thickness is less than the width of the guide groove.

[0013] Furthermore, a ramp is provided at the bottom of the guide groove to guide the lower end of the push rod to slide towards the limiting groove.

[0014] Furthermore, the clamping rod provides the elasticity required to clamp the plastic diaphragm via a clamping spring mounted on the turntable.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a push rod with swinging and lifting functions positioned directly above the turntable receiving seat of an aluminum electrolytic capacitor assembly machine. A guide groove communicating with a core package limiting groove is provided on the limiting seat of the receiving seat. When the push rod descends, its lower end enters the guide groove. When the push rod swings, its lower end is guided along the guide groove into the limiting groove, pushing the capacitor core package or plastic diaphragm in the limiting groove out of the receiving seat. This achieves the purpose of automatically and quickly pushing defective products away from the receiving seat, meeting the needs of automated production of aluminum electrolytic capacitors.

[0024] See Figures 1-4 This utility model relates to a turntable for assembling aluminum electrolytic capacitors. The turntable is circular (1), and several receiving seats (2) are evenly arranged on its outer circumference. Each receiving seat (2) includes a support base (21) connected to the turntable (1), a limiting seat (22) on the support base (21), and a clamping rod (23) movably disposed beside the limiting seat (22). The clamping rod (23) provides the elasticity required to clamp the plastic diaphragm via a clamping spring (27) mounted on the turntable (1). The support base (21) has a receiving groove (24) for accommodating guide pins. The limiting seat (22) has a semi-cylindrical limiting groove (25).

[0025] During the assembly of aluminum electrolytic capacitors, turntable 1 rotates intermittently at a certain production rhythm. A diaphragm feeding device located next to turntable 1 places plastic diaphragms 4 one by one onto the support base 21, and the position is limited by the limiting seat 22. At the same time, the clamping rod 23 clamps and fixes the plastic diaphragms 4. Then, a core pack feeding device located next to turntable 1 places the core pack 5 with leads onto the plastic diaphragm 4, and inserts the guide pin 6 at the bottom of the core pack 5 into the guide pin hole of the plastic diaphragm 4. The guide pin 6 passes through the plastic diaphragm 4 and extends into the receiving groove 24. If there are abnormal situations such as missing plastic diaphragms 4, missing core packs 5, or bent guide pins 6, causing the core pack 5 and diaphragm 4 to be unqualified, the detection device will issue an unqualified signal.

[0026] A push rod 3 is mounted on a lifting mechanism directly above the receiving seat 2. The push rod 3 swings back and forth like a pendulum through a swinging mechanism mounted on the lifting mechanism. The lifting mechanism includes a bracket 31, on which the push rod 3 is mounted. A lifting cylinder 32 pushes the bracket 31, thereby driving the push rod 3 to move up and down. The swinging mechanism is rotatably mounted on a rotating shaft 33 on the bracket 31. The push rod 3 is vertically mounted at one end of the rotating shaft 33, and a swing arm 34 is mounted at the other end of the rotating shaft 33. The free end of the swing arm 34 is pulled downward by a swing spring 35, and the middle part is pushed upward by a swing cylinder 36, thereby driving the rotating shaft 33 and the push rod 3 to perform a pendulum motion. When a non-conforming signal is received, the lifting mechanism and the swinging mechanism sequentially drive the push rod 3 to descend and then swing. After completion, it automatically resets to its original position to wait for the next non-conforming signal to appear, without affecting the normal production process.

[0027] The limiting seat 22 is provided with a guide groove 26 for accommodating the bottom end of the push rod 3, and the guide groove is connected to the limiting groove 25. The lower end of the push rod 3 has a flat structure, and its thickness is less than the width of the guide groove 26. After the push rod 3 descends, the lower end of the push rod 3 enters the guide groove 26. A ramp is set at the bottom of the guide groove 26 to guide the lower end of the push rod 3 to slide towards the limiting groove 25. Subsequently, the push rod 3 is controlled by a pendulum motion to slide the lower end of the push rod 3 along the guide groove 26 into the limiting groove 25, thereby pushing the unqualified capacitor assembly clamped in the receiving seat 2 to resist the clamping resistance and quickly detach from the receiving seat 2, preventing it from entering the next process and achieving the purpose of automatically rejecting unqualified products.

[0028] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
