Description

TECHNICAL FIELD

[0001] The present application belongs to the field of electroplating of electronic components with elongated leads, and relates to a barrel plating device for electronic components with elongated leads. BACKGROUND

[0002] With the rapid development of the existing electronic industry, the complexity of devices is gradually increasing, and the electronic components required by the industry present the characteristics of small size, many thin leads, etc. The conventional electroplating process adopts hanging plating and barrel plating process for production. At present, the conventional hanging plating process cannot meet the requirements of large quantities and low cost of customers due to low production rate and large amount of maintenance of equipment and auxiliary tools.

[0003] The existing conventional barrel plating process is prone to cause lead bending damage due to the large gap between the barrel screen and the plating process. The conventional barrel device is affected by the current distribution due to the large internal cloth edge area and the small through-hole area for internal and external exchange, thereby leading to inconsistent plating layer thickness, and even causing batch rejection. SUMMARY

[0004] To solve the above technical problems, the present application adopts a barrel plating device for electronic components with elongated leads, which comprises a barrel 1, a barrel plating frame 2 and a motor mechanism 3. The barrel 1 is arranged on the barrel plating frame 2, and the motor mechanism 3 is arranged on the barrel plating frame 2 and connected with the barrel 1.

[0005] The barrel 1 is a hexagonal prism structure composed of two hexagonal side plates 11 and six quadrilateral bottom plates 12.

[0006] The quadrilateral bottom plate 12 has a plurality of through holes.

[0007] The barrel 1 further comprises a screen cloth and a pressing strip 13, and the screen cloth is fixed on the quadrilateral bottom plate 12 by the pressing strip 13 and a screw. The pressing strip 13 is arranged outside the barrel 1.

[0008] The material of the barrel 1 is any one of polypropylene resin and transparent organic glass.

[0009] The motor mechanism 3 comprises a motor 31, a relay 32 and a motor speed adjusting device 33. The motor 31, the relay 32 and the motor speed adjusting device 33 are connected with an external power supply. The motor 31 and the relay 32 are connected in parallel, and the motor 31 is connected in series with the motor speed adjusting device 33.

[0010] The motor mechanism 3 further comprises a shaft coupling 35 and an encoder 36. One end of the shaft coupling 35 is connected with the motor 31, and the other end is connected with the encoder 36.

[0011] The motor mechanism 3 further comprises a sealing box 34, and the motor 31, the relay 32 and the motor speed adjusting device 33 are arranged inside the sealing box 34.

[0012] The roller 1 is connected to the motor mechanism 3 by a three-tooth meshing method.

[0013] Beneficial effects:

[0014] 1. This invention addresses the characteristics of slender lead electronic components. Unlike traditional single-fixation methods, it uses slender pressure strips and screws to fix the mesh, reducing the edge stretching of the mesh, maintaining a flat internal structure, and effectively reducing the internal gap of the drum, thereby reducing the occurrence of lead bending. 2. The drum mesh is fixed with external pressure strips, unlike internal fixing methods. This increases the contact area of ​​the mesh and avoids interference with the sidewalls, reducing the number of gaps and thus lowering the frequency of scratching of electronic components. This also increases the opening area of ​​the sidewalls, facilitating the exchange of liquids inside and outside the drum. 3. The drum plating equipment of this invention adds a motor speed adjustment device to the outside of the motor and uses a flexible coupling to connect the encoder, displaying and monitoring speed and other values ​​in real time. Abnormal situations are fed back to the control center in real time, avoiding lead bending or product batch scrapping caused by abnormal speed during electroplating. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention employs a barrel plating apparatus for slender lead electronic components, comprising: a barrel 1, a barrel plating frame 2, and a motor mechanism 3; the barrel 1 is mounted on the barrel plating frame 2, and the motor mechanism 3 is mounted on the barrel plating frame 2 and connected to the barrel 1.

[0026] Preferably, such as Figure 4 As shown, the motor mechanism 3 is connected to the drum 1 via a three-tooth meshing method.

[0027] like Figure 2 , Figure 3 As shown, the roller 1 is a hexagonal prism structure composed of two hexagonal side plates 11 and six quadrilateral base plates 12, and the plates are connected by screws.

[0028] The material of roller 1 can be polypropylene resin or transparent plexiglass. The former is corrosion-resistant, high temperature resistant and high strength, while the latter is less resistant to high temperature. However, its unique transparency makes it easy for users to observe the operation of the internal products in real time.

[0029] Structurally, the quadrilateral base plate 12 adopts a porous structure design.

[0030] The roller 1 also includes a mesh and a slender pressure strip 13. The mesh is fixed to the quadrilateral base plate 12 by screws through the slender pressure strip 13, which reduces the stretching edge of the mesh and maintains the flatness of the internal structure, thereby effectively reducing the internal gap of the roller and reducing the occurrence of wire bending.

[0031] The mesh can also be fixed with external pressure strips, which, unlike internal fixing methods, reduces the number of gaps and thus reduces the frequency of product scratches; it also increases the contact area of ​​the mesh, thereby increasing the opening area of ​​the side wall, which is beneficial for the exchange of liquid inside and outside the roller.

[0032] The motor mechanism 3 includes: a motor 31, a relay 32, and a motor speed regulating device 33; the motor 31, relay 32, and motor speed regulating device 33 are connected to an external power supply; wherein, as shown... Figure 8 As shown, motor 31 and relay 32 are connected in parallel, and motor 31 is connected in series with motor speed regulating device 33. Motor speed regulating device 33 adjusts the motor speed in real time through an external knob, thereby controlling the frequency of drum rotation.

[0033] The motor mechanism 3 also includes: a coupling 35 and an encoder 36; such as Figure 5 , Figure 6 As shown, one end of coupling 35 is connected to motor 31, and the other end is connected to encoder 36. A flexible coupling 35 is used to connect to encoder 36, allowing for real-time display and monitoring of values ​​such as rotational speed. Abnormal situations are fed back to the control center in real time, preventing product batch scrapping caused by wire bending or power failure due to abnormal rotational speed during electroplating. The addition of a flexible coupling in the middle serves to reduce vibration and noise, while also accommodating certain shaft eccentricities and angular deviations.

[0034] like Figure 7 As shown, the motor mechanism 3 also includes a sealed box 34, and the motor 31, relay 32 and motor speed regulating device 33 are installed inside the sealed box 34 to prevent corrosion of the internal equipment in an acidic environment.

[0035] The above-described embodiments further illustrate the purpose, technical solution, and advantages of the present invention. It should be understood that the above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made to the present invention within the spirit and principles of the present invention should be included within the protection scope of the present invention.
