Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing equipment, and more specifically, to a drying device for workpieces after electroplating. Background Art

[0002] Workpiece electroplating is the process of plating a thin layer of other metals or alloys on the surface of metal workpieces using the principle of electrolysis. It mainly prevents the workpiece from oxidation (such as rust), improves wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhances aesthetics.

[0003] In order to enhance the electroplating effect, the surface after electroplating needs to be dried. After drying, the tightness between the electroplated film layer and the workpiece surface can be effectively enhanced, and the corrosion of the electroplated layer surface by water stains on the electroplated surface can be avoided. For the drying of the workpiece, a box-type drying equipment is generally used for overall drying. The workpiece is placed on a tray and sent to the drying area of ​​the equipment. Drying gas is introduced or wind is used for drying. After drying, another batch of workpieces that need to be dried is replaced. There is a gap time for waiting for drying and a gap time generated during the replacement process. If multiple drying equipment are used at the same time, the cost will increase. Therefore, although the traditional drying method can provide a drying effect for the workpiece, the overall drying efficiency cannot reach the best.

[0036] like Figure 1-8 As shown, the utility model provides a drying device for workpieces after electroplating, comprising a box body 1, a feed port 101 and a discharge port 103 are respectively arranged on both sides of the box body 1, a guide plate extending inward is arranged on the discharge port 103, a partition net 102 is arranged on the top of the box body 1, and also comprises a drying device 2 arranged inside the box body 1 and corresponding to the positions of the feed port 101 and the discharge port 103, the drying device 2 comprises a driving device 3, a workpiece guiding device 4, a carrying box 5 and a gas guiding device 6;

[0037] The workpiece guiding device 4 is composed of two disc seats 401 of corresponding sizes and positions with a gap between them;

[0038] The carrying boxes 5 are provided in multiple groups and are arranged on the circular end surfaces outside the two disc seats 401 according to the circumference. The carrying boxes 5 are in a semi-closed hollow structure as a whole and are connected to the gap between the two disc seats 401;

[0039] Specifically, the plurality of circumferentially distributed bearing boxes 5 can mainly realize continuous feeding of the workpieces and achieve the effect of cyclic drying. Considering that the drying gas is discharged from between the two disc seats 401 and the drying gas penetrates the bearing box 5 at the same time, so that the workpiece can be fully in contact with the gas, the bearing box 5 adopts a hollow structure, and the gap between the two disc seats 401 is mainly used to install the gas guide device 6;

[0040] The gas guiding device 6 is rotatably connected to the gap between the two disc seats 401 through a bearing sleeve 402 disposed on one of the two disc seats 401, and is used for guiding the drying gas;

[0041] Specifically, the gas guiding device 6 guides the drying gas in a dispersed manner so that the drying gas can fully contact the workpieces in the multiple groups of carrying boxes 5 arranged on the rotating disc seat 401 to achieve drying;

[0042] The driving device 3 is arranged on the box body 1 corresponding to the center of the disc seat 401, and the driving device 3 includes a transmission box 301 for rotating the workpiece guide device 4 and the gas guide device 6 in different directions and a motor 302 for driving the transmission box 301;

[0043] Specifically, the driving device 3 mainly drives the transmission assembly 7 in the transmission box 301 through the motor 302, and the transmission assembly 7 simultaneously realizes the synchronous relative rotation of the disc seat 401 and the gas guide device 6, thereby improving the comprehensiveness of drying;

[0044] In summary, when drying the workpiece after electroplating, the drying device adopts a circulating drying method. The motor 302 drives the workpiece guide device 4 and the gas guide device 6 of the drying device 2 to rotate relative to each other through the transmission box 301. The drying gas is directly introduced into the circular seat 601 through the air inlet pipe 603. In conjunction with the rotation of the circular seat 601, the drying gas is guided into the gap between the two disc seats 401 through multiple sets of gas guide covers 602, and then diffused outward from the gap. The workpiece is embedded into the carrier from the feed port 101. At the loading end face of the box 5, under the guidance of the disc seat 401, due to the inclined structure of the loading end face, when it is rotated to the first flipping position, the workpiece will flip to the connecting end face of the carrying box 5, and the connecting end face is also inclined. When it is rotated to the second flipping position, the workpiece will flip to the unloading end face of the carrying box 5, and continue to rotate until it falls onto the guide plate of the discharge port 103. Through the secondary flipping, the position of the workpiece is replaced, so that the diffused dry gas can contact different end faces of the workpiece, thereby achieving a drying effect on the workpiece;

[0045] It should be noted that the first flip position and the second flip position are determined according to the inclination angle of the loading end surface and the inclination angle of the connecting end surface of the carrying box 5;

[0046] In order to achieve the circulation drying of multiple workpieces at the same time, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the carrying box 5 includes a connecting seat 502 which is hollow and connected to the two disc seats 401 and a frame 501 which is arranged on the connecting seat 502 and is used to place the workpiece, and the frame 501 and the connecting seat 502 are in a communicating structure;

[0047] Further explained, the carrying box 5 is installed on the disc base 401 and can rotate with the disc base 401. By using the circular rotation, multiple carrying boxes 5 for carrying workpieces can be arranged on the disc base 401, thereby achieving a cyclic drying effect;

[0048] At the same time, the feeding end face, the unloading end face and the end face connected to the connection seat 502 of the frame 501 are all in a strip-shaped mesh structure, and the two sides adjacent to the feeding end of the frame 501 are provided with a cross structure formed by multiple groups of support rods;

[0049] Further defined, the end surface where the frame 501 is connected to the connection seat 502 is set at an oblique angle, the feeding end surface of the frame 501 is set obliquely toward the inner side of the frame 501 and a baffle 503 is set at the port of the feeding end surface, and the unloading end surface of the frame 501 is set parallel to the connection seat 502;

[0050] According to the description of the structure of frame 501, see Figure 6 As shown, in order to achieve the position adjustment of the workpiece in the carrying box 5, the loading end face, the unloading end face and the connecting end face with the connecting seat 502 of the strip-shaped mesh structure can limit the corners of the workpiece through the strip structure, so that the workpiece can be easily turned over after the position of the carrying box 5 is adjusted. At the same time, in order to achieve the turning of multiple positions in the carrying box 5 during the entire circular motion of the workpiece, the loading end face and the connecting end face are set to an oblique structure. When the disc seat 401 rotates to a specific position, the inclined loading end face and the connecting surface can realize the position turning of the workpiece to achieve the effect of multi-position exchange, thereby realizing multi-angle drying of the workpiece.

[0051] At the same time, in order to improve the stability of the workpiece after loading, a baffle 503 is provided at the loading end surface to prevent the workpiece from accidentally falling during loading;

[0053] Furthermore, in order to ensure the circulation of gas while the gas guiding device 6 rotates, the air inlet pipe 603 is connected to the circular seat 601 of the gas guiding device 6 through the bearing sleeve 402 to ensure the flow of dry gas while the circular seat 601 rotates;

[0054] In order to realize the linear relative rotation between the disc seat 401 and the circular seat 601, as shown in FIG. Figure 7 and Figure 8As shown, a transmission assembly 7 is provided inside the motor 302, and the transmission assembly 7 is composed of a first bevel gear 8, a second bevel gear 9, a third bevel gear 10 and a U-shaped frame 11; wherein, the first bevel gear 8 is provided with an integrated sleeve rod 801 and a first fixed disk 802 provided on the sleeve rod 801 for connecting the disk seat 401, the sleeve rod 801 is a hollow structure and is connected to the first bevel gear 8 through the sleeve rod 801; the second bevel gear 9 is provided with a transmission end connected to the transmission box 301 Rod 901, one end of the transmission rod 901 passes through the first bevel gear 8 and is connected to the outside of the sleeve rod 801, and a second fixing plate 902 for connecting the circular seat 601 is provided on the through portion of the transmission rod 901; the third bevel gear 10 is rotatably connected to the center of the inner end surface of the U-shaped frame 11, and both ends of the U-shaped frame 11 are provided with a limiting sleeve 1101 for limiting the sleeve rod 801 and the transmission rod 901, and the third bevel gear 10 is meshed and connected with the first bevel gear 8 and the second bevel gear 9 at the same time;

[0055] Specifically, through the nested structure of two groups of bevel gears, in conjunction with a group of gears that realize transmission at the same time, while the second bevel gear 9 rotates forward, the first bevel gear 8 will reverse through the third bevel gear 10, and at the same time the second bevel gear 9 will drive the sleeve rod 801 to rotate, thereby realizing the relative rotation of the sleeve rod 801 and the transmission rod 901, that is, the relative rotation of the disc seat 401 and the circular seat 601.
