[0018] The structure and other aspects of the automatic slurry dipping device of the present invention are further described in detail below through specific implementations and with reference to the accompanying drawings.

[0019] like Figure 1As shown, the automatic slurry dipping device of the utility model is used to automatically infiltrate the end of the metal wire 90 with metal slurry, such as silver slurry or gold slurry. Before the metal slurry is infiltrated, the metal wire 90 is arranged on the flat plate 91 at equal intervals. In a preferred embodiment, the flat plate 91 is provided with transverse grooves 911 at equal intervals, and the metal wire 90 is placed in the transverse grooves 911. The automatic slurry dipping device of the utility model generally includes a slurry supply device 21, a flat plate pushing device 22 and a wire pressing device 23. The slurry supply device 21 is used to automatically infiltrate the end of the metal wire with metal slurry. The flat plate pushing device 22 is used to push the flat plate 91 horizontally along the first direction X. The wire pressing device 23 is used to position the metal wire 90 on the flat plate 91 during slurry dipping to prevent the metal wire 90 from moving.

[0020] like Figure 2 and Figure 3 As shown, in one embodiment, the slurry supply device 21 includes a rotatable feed roller 211, a slurry heating device 212 and a drive 213 cylinder 214, wherein the drive motor 213 drives the feed roller 211 to rotate through a belt 215, and the cylinder 214 is used to drive the feed roller 211 and the slurry heating device 212 to move horizontally along the slide rail 216 toward the direction close to the metal wire 90 or toward the direction away from the metal wire 90. At least one circumferential groove 211a is provided on the circumferential surface of the feed roller 211. In this embodiment, four circumferential grooves 211a are provided on the circumferential surface of the feed roller 211, so that the ends of four wires can be infiltrated with metal slurry at one time. The slurry heating device 212 is used to heat and melt solid metal. The slurry heating device 212 has a cavity 212a for accommodating metal slurry. At least a portion of the circumferential surface of the feed roller 211 is located in the cavity 212a. At least a portion of the feed roller 211 extends into the cavity 212a and the circumferential surface of the feed roller 211 is immersed in the metal slurry so that the circumferential groove 211a of the feed roller 211 is filled with the metal slurry. A collecting groove 217 for collecting leaked material is also provided below the feed roller 211, and the metal slurry leaked from the feed roller 211 is collected in the collecting groove 217.

[0021] like Figure 4 and Figure 5As shown, in one embodiment, the flat plate pushing device 22 includes a claw 221, a bracket 222 and a driving motor 223, the driving motor 223 is connected to the screw rod 224 to drive the screw rod 224 to rotate, and the screw rod 224 is connected to the bracket 222 through a connecting member 225. The bracket 222 can move left and right along the slide rail 227 provided on the base 226. The driving motor 223 drives the screw rod 224 to rotate, and when the screw rod 224 rotates, the connecting member 225 moves left and right along the screw rod 224, and the connecting member 225 further drives the bracket 222 to move left and right along the slide rail 227. The claw 221 is fixed to the end of the rotating shaft 228, and the rotating shaft 228 can rotate around its axis. In this embodiment, claws 221 are provided at both ends of the rotating shaft 228. The rotating shaft 228 is rotatably supported on the bracket 222. A rotating member 229 is fixed to the middle of the rotating shaft 228, and one end of the rotating member 229 is connected to a pull rod 230. The pull rod 230 can move up and down under the drive of a driving mechanism (not shown). The rotating member 229 rotates around the center of the rotating shaft 228 under the action of the pull rod 230, and the rotating shaft 228 fixed to the rotating member 229 also rotates at the same time, thereby driving the claws 221 at both ends of the rotating shaft 228 to approach or move away from the flat plate 91. When the claw 221 approaches the flat plate 91, the end of the claw 221 extends into the horizontal groove 911 of the flat plate 91. When the claw 221 moves horizontally, the claw 221 can push the flat plate 91 to move horizontally together.

[0022] like Figure 6 As shown, in one embodiment, the wire pressing device 23 includes at least one pressing head 231, a slider 232 for mounting the pressing head 231, and a cantilever 233. The pressing head 231 is mounted on the slider 232, and the slider 232 can move up and down along the second direction Y under the action of the cylinder 234. The slider 232 is located at one end of the cantilever 233, and the cantilever 233 is fixed on the bracket 235. When the slider 232 moves downward, it drives the pressing head 231 to approach and contact the metal wire 90 on the flat plate 91. In this embodiment, four pressing heads 231 are arranged on the slider 232, so that the pressing heads 231 can press four metal wires at a time.

[0023] In a specific embodiment, the transverse groove 911 on the flat plate 91 has a middle notch 912, and the pressure head 231 is located at the middle notch 912 when it moves downward along the second direction Y. The purpose of setting the middle notch 912 is to enable the pressure head 231 to directly contact the metal wire on the flat plate 91 so as to position the wire on the flat plate to prevent the wire 90 from moving left and right in the transverse groove 911.

[0024] When the automatic slurry dipping device of the utility model is working, a metal wire 90 is placed on the flat plate 91, and the flat plate pushing device 22 pushes the flat plate 91 to move horizontally along the first direction X. When the metal wire 90 on the flat plate 91 reaches the position relative to the feeding roller 211, the pressing head 231 of the wire pressing device 23 moves downward to contact the metal wire 90 and position the metal wire 90 on the flat plate 91. The cylinder 214 of the slurry supply device 21 drives the feeding roller 211 to approach the metal wire 90 until the end of the metal wire 90 extends into the circumferential groove 211a on the circumferential surface of the feeding roller 211. Before the feeding roller 211 moves horizontally, it first rotates and fills the circumferential groove 211a with metal slurry during the rotation. When the end of the metal wire 90 extends into the circumferential groove 211a, the end can be soaked with metal slurry. Afterwards, the feeding roller 211 moves away from the metal wire 90, and the pressing head 231 of the wire pressing device 23 moves upward to move away from the metal wire 90. The flat plate pushing device 22 pushes the flat plate 91 to move laterally along the first direction X again. In this way, the end of the metal wire can be automatically wetted with metal slurry.

Modifications, equivalent substitutions and other improvements to the above embodiments that are obvious to those skilled in the art are also within the concept of the utility model.
