Description

Technical Field

[0001] The invention belongs to the field of electroplating of slender lead electronic components, and relates to a barrel plating device for slender lead electronic components. Background Art

[0002] With the rapid development of the existing electronics industry, the complexity of devices has gradually increased. The electronic components required by the industry are characterized by small size, many and thin leads, etc. Conventional electroplating processes use hanging plating and barrel plating processes for production. At present, due to the low productivity of the conventional hanging plating process and the large amount of maintenance of equipment and auxiliary tools, it cannot meet the requirements of customers for large quantities and low costs.

[0003] In the existing conventional barrel plating process, due to the large gap between the drum mesh plates, the leads are easily stuck during the operation of the equipment, resulting in bending damage to the leads. In the conventional drum equipment, due to the large edge area of the internal stretched cloth and the small through-hole area for internal and external exchange, the current distribution is affected, and then the coating thickness is inconsistent, and in severe cases, even batch scrapping will occur. Summary of the Invention

[0004] To solve the above-mentioned problems of the existing technology, the invention adopts a barrel plating device for slender lead electronic components, including: a drum 1, a barrel plating rack 2 and a motor mechanism 3; the drum 1 is arranged on the barrel plating rack 2, and the motor mechanism 3 is arranged on the barrel plating rack 2 and connected to the drum 1.

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

[0006] There are multiple through-holes on the quadrilateral bottom plate 12.

[0007] The drum 1 further includes a mesh cloth and a pressing strip 13. The mesh cloth is fixed on the quadrilateral bottom plate 12 by the pressing strip 13 and screws. The pressing strip 13 is arranged outside the drum 1.

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

[0009] The motor mechanism 3 includes: a motor 31, a relay 32 and a motor speed regulating device 33; the motor 31, the relay 32 and the motor speed regulating device 33 are connected to an external power supply; wherein, the motor 31 and the relay 32 are connected in parallel, and the motor 31 is connected in series with the motor speed regulating device 33.

[0010] The motor mechanism 3 further includes: a coupling 35 and an encoder 36; one end of the coupling 35 is connected to the motor 31, and the other end is connected to the encoder 36.

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

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

[0013] Beneficial effects:

[0014] 1. In view of the characteristics of slender-lead electronic components, the present invention, different from the traditional single-fixed method of the mesh cloth, uses a slender-shaped pressing strip and screws to fix the mesh cloth, reducing the edge of the stretched mesh cloth and keeping the internal structure flat, thereby effectively reducing the internal gap of the roller and then reducing the occurrence of lead bending; 2. The mesh cloth of the roller is fixed by an external pressing strip, different from the internal fixing method, which improves the contact area of the mesh cloth and avoids interference with the side wall, reduces the number of gaps, thereby reducing the frequency of scratching of electronic components, and then can increase the opening area of the side wall, which is beneficial to the liquid exchange inside and outside the roller; 3. The barrel plating equipment of the present invention adds a motor speed regulating device outside the motor, and uses a flexible coupling to connect the encoder, real-time displays and monitors values such as the rotation speed, and in case of abnormal conditions, it feeds back to the control center in real time, avoiding lead bending caused by abnormal rotation speed or product batch scrapping caused by power failure during the electroplating process.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 shown, the present invention adopts a barrel plating device for slender lead electronic components, including: a drum 1, a barrel plating rack 2, and a motor mechanism 3; the drum 1 is arranged on the barrel plating rack 2, and the motor mechanism 3 is arranged on the barrel plating rack 2 and connected to the drum 1.

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

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

[0028] The material of the drum 1 can be polypropylene resin or transparent organic glass. The former is corrosion-resistant, high-temperature resistant, and has high strength. The latter has relatively weak high-temperature resistance, but its unique transparency facilitates users to observe the internal product operation situation in real time;

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

[0030] The drum 1 further includes a mesh cloth and an elongated pressure strip 13. The mesh cloth is fixed to the quadrilateral bottom plate 12 by the elongated pressure strip 13 and screws, reducing the edge of the stretched cloth of the mesh cloth, maintaining the flatness of the internal structure, thereby effectively reducing the internal gap of the drum, and then reducing the occurrence of lead bending.

[0031] The mesh cloth can also be fixed by an external pressure strip. Different from the internal fixing method, the number of gaps is reduced, thereby reducing the frequency of product scratching; the contact area of the mesh cloth is increased, and then the side wall opening area is increased, which is beneficial to the exchange of liquid inside and outside the drum.

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

[0033] The motor mechanism 3 further includes: a coupling 35 and an encoder 36; as Figure 5 , Figure 6 shown, one end of the coupling 35 is connected to the motor 31, and the other end is connected to the encoder 36. The flexible coupling 35 is used to connect the encoder 36 to display and monitor values such as the rotational speed in real time, and abnormal conditions are fed back to the control center in real time to avoid the bending of leads caused by abnormal rotational speed or the scrapping of product batches caused by power failure during the electroplating process. A flexible coupling is added in the middle for buffering and noise reduction, and it can also adapt to a certain axial eccentricity and angular deviation.

[0034] As Figure 7 shown, the motor mechanism 3 further includes a sealed box 34, and the motor 31, the relay 32, and the motor speed regulating device 33 are arranged inside the sealed box 34 to prevent the internal equipment from being corroded in an acidic environment.

[0035] The above-mentioned embodiments further illustrate the purpose, technical solutions, and advantages of the present invention in detail. It should be understood that the above-mentioned embodiments are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made to the present invention within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
