DETAILED DESCRIPTION

[0024] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the water washing tank used in the production of diode leads. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] like Figure 1-4 As shown, a water washing tank for diode lead production includes a tank body 1, the tank body 1 is provided with a drying mechanism 2, the drying mechanism 2 includes a wind tube 22 fixedly connected to the tank body 1, the wind tube 22 has an outlet pipe 225, an inlet pipe 222 connected to the inside of the tank body 1 and an air inlet pipe 221 connected to an air pump 21, and a water absorption block 26 is also provided at the inlet pipe 222.

[0027] The above-mentioned water washing tank can be used for but not limited to cleaning the diode lead. Clean water is injected into the tank body 1. During cleaning, the lead enters the tank body 1 and is cleaned with clean water. Then the lead passes through the water absorption block 26. During this process, a large amount of water on the lead is absorbed by the water absorption block 26, so as to achieve rapid preliminary drying of the lead. The water absorption block 26 can be a sponge block. The sponge block is soft and has good water absorption performance. It can quickly absorb a large amount of water on the lead without scratching the lead. Then the lead enters the air duct 22 through the inlet pipe 222, and the air pump 21 blows external dry air into the air duct 22 to form an airflow inside the air duct 22. The small amount of water remaining on the lead can be dried by the airflow, so as to complete the drying of the lead, thereby reducing the probability of oxidation of the lead, improving the quality of the lead, and facilitating subsequent processing of the lead.

[0028] In the water washing tank, the lead wire can be dried twice by the airflow inside the water absorbent block 26 and the wind tube 22, which can improve the drying speed while ensuring the drying effect; after the external airflow enters the wind tube 22, part of the airflow can be blown onto the water absorbent block 26 from the wire inlet pipe 222, thereby achieving the drying of the water absorbent block 26, and then improving the drying effect of the water absorbent block 26 on the lead wire.

[0029] A further improvement is, Figure 1-4As shown, the air cylinder 22 is vertically arranged just above the tank body 1, the inlet pipe 222 is coaxially arranged at the bottom of the air cylinder 22, the water absorption block 26 is arranged on the bottom end of the inlet pipe 222, and is located inside the tank body 1. The lead wires after cleaning in the tank body 1 pass through the water absorption block 26 and the inlet pipe 222 in sequence vertically upward. In the above-mentioned water washing tank, a guide wheel for guiding the forward direction of the lead wire can be arranged inside the tank body 1. The moving direction of the lead wire when it is out of water is vertically upward, so that the water on the lead wire can flow down quickly along the lead wire under the action of gravity, reducing the amount of water remaining on the lead wire after the lead wire is out of water, thereby reducing the pressure when the lead wire is dried later, so as to ensure the drying effect of the lead wire.

[0030] A further improvement is, Figure 3-5 As shown, a mesh box 25 for containing a desiccant is provided inside the air duct 22. After the moisture on the lead wire is dried by the air flow, the humidity inside the air duct 22 will increase, affecting the drying effect of the lead wire inside the air duct 22. The desiccant provided inside the mesh box 25 can absorb the moisture in the air inside the air duct 22, thereby reducing the humidity inside the air duct 22 to improve the drying effect on the lead wire.

[0031] A further improvement is, Figure 3-5 As shown, the mesh box 25 is a flat structure and is provided in plurality, and each mesh box 25 is evenly spaced and distributed on the inner wall of the wind tube 22 around the axis of the wind tube 22. When the mesh box 25 is filled with desiccant, the flat mesh box 25 can make the area of ​​the desiccant in contact with the air larger, thereby improving the drying effect of the air inside the wind tube 22; compared with last year, the mesh boxes 25 are evenly distributed inside the wind tube 22, which can effectively dry the air everywhere inside the wind tube 22, calmly and effectively reduce the humidity inside the wind tube 22, and improve the drying effect of the lead wire.

[0032] A further improvement is, Figure 3-5 As shown, the top opening of the wind tube 22 is covered with a top cover 224, the outlet pipe 225 is arranged on the top cover 224, and is coaxially arranged with the inlet pipe 222, and the net box 25 is detachably connected to the wind tube 22. A slot 223 is arranged on the inner wall of the wind tube 22 along the axial direction of the wind tube 22, and a plug strip 251 is arranged on the net box 25, and the plug strip 251 is plugged and matched with the slot 223, so that the net box 25 and the wind tube 22 can be disassembled and assembled, and the opening and closing of the top cover 224 can facilitate the replacement of the net box 25, thereby improving the convenience of using the water washing tank; the lead wire inside the wind tube 22 is dried and then comes out from the outlet pipe 225 for winding or subsequent operations.

[0033] A further improvement is, Figure 3 and 4As shown, the bottom end of the inlet pipe 222 is coaxially connected to the dehydration cylinder 24, and the water absorption block 26 is arranged inside the dehydration cylinder 24. When the dehydration cylinder 24 rotates, the water on the lead wire absorbed by the water absorption block 26 will be separated from the water absorption block 26 under the action of centrifugal force, thereby achieving the drying of the water absorption block 26, so as to improve the drying effect of the water absorption block 26 on the lead wire.

[0034] A further improvement is, Figure 3 and 6 As shown, a connecting sleeve 245 is coaxially arranged on the top of the dehydration cylinder 24, and the connecting sleeve 245 is coaxially sleeved on the outer periphery of the inlet pipe 222. The connecting sleeve 245 and the inlet pipe 222 are connected through a bearing 244, and the tank body 1 is provided with a driving unit 23 for driving the connecting sleeve 245 to rotate. The driving unit 23 includes a motor fixedly connected to the tank body 1, and a driving gear is fixedly connected to the rotating shaft of the motor. A gear ring 241 meshing with the driving gear is sleeved on the outer periphery of the connecting sleeve 245. The motor provides power, and the driving gear and the gear ring 241 are driven, so that the connecting sleeve 245 rotates, and then drives the dehydration cylinder 24 to rotate, and the water inside the water absorption block 26 is separated by the dehydration cylinder 24, and the water absorption effect of the water absorption block 26 is improved.

[0035] A further improvement is, Figure 6 As shown, a plurality of drainage grooves 242 are evenly spaced around the axis of the dehydration cylinder 24. The arrangement of the drainage grooves 242 can facilitate the drainage of the water inside the dehydration cylinder 24, thereby improving the dehydration effect; at the same time, the drainage grooves 242 can make the surface of the dehydration cylinder 24 rough, increase the friction between the water absorption block 26 and the dehydration cylinder 24, and enable the dehydration cylinder 24 to more effectively drive the water absorption block 26 to rotate, thereby removing the water inside the water absorption block 26.

[0036] A further improvement is, Figure 6 As shown, a flange 243 is provided inside the bottom end of the dehydration cylinder 24. The flange 243 can limit the water absorption block 26 inside the dehydration cylinder 24, prevent the water absorption block 26 from detaching from the inside of the dehydration cylinder 24, and improve the stability of the connection between the two.
