Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular to a zinc pot zinc liquid replenishment device. Background Technology

[0002] A zinc bath replenishment device is used to maintain the concentration of zinc ions in the zinc bath during the electroplating process. During electroplating, the zinc ions in the zinc bath are gradually depleted over time, requiring periodic replenishment to maintain stable electroplating results and quality.

[0003] Traditional zinc bath replenishment devices have the following drawbacks: 1. They lack a structure for conveniently raising and lowering the zinc rod, making it difficult to maintain close proximity to the bottom of the core rod for efficient zinc replenishment. Therefore, we propose a zinc pot zinc bath replenishment device. Summary of the Invention

[0004] The main objective of this invention is to provide a zinc pot zinc liquid replenishment device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A zinc pot liquid replenishment device includes a bottom plate, a through groove, a pot body, a discharge pipe, an electric heater, a disc-shaped top plate, a pre-drilled hole, and zinc rods. A vertical plate is welded to one end of the top of the bottom plate. A servo motor is mounted on one end of the vertical plate near the bottom via a fixed base. The output shaft of the servo motor is connected to a lead screw. A lead screw is sleeved around the lead screw. A disc-shaped top plate is welded to one end of the lead screw. A pre-drilled hole is formed through the top of the disc-shaped top plate, and a zinc rod is placed inside the pre-drilled hole. A through groove is formed near the center of the top of the bottom plate. First support plates are provided at both ends of the through groove on the top of the bottom plate. The pot body is connected to the top of the first support plates. An electric heater is fixed to the outer wall of the pot body via connecting bolts. An annular outer wall is welded to the bottom of the disc-shaped top plate near its edge, and the bottom of the annular outer wall is located outside the top of the pot body.

[0007] Furthermore, a second support plate is welded to the top of the base plate near both ends, and an annular limiting baffle is connected to the top of the second support plate. The annular limiting baffle is located on the outer periphery of the annular outer wall.

[0008] Furthermore, a slide rail is provided at one end of the upright plate near the center, the end of the wire block is located inside the slide rail, an extension block is welded to one side of the top of the upright plate, a bearing is provided at the bottom of the extension block, and the top of the lead screw is located inside the bearing. Through the limiting and guiding effect of the slide rail on the wire block and the limiting and guiding effect of the bearing on the lead screw, the stability of the wire block when moving up and down can be effectively improved.

[0009] Furthermore, a thermostat is fixed to one end of the upright plate near the bottom via a connecting rod, and the power output terminal of the thermostat is electrically connected to the power input terminal of the electric heater via a wire.

[0010] Furthermore, protrusions are welded to both ends of the base plate near the bottom. The bottom of each protrusion has a through-hole for mounting. External bolts are passed through the mounting holes to facilitate fixing the protrusions to the external surface to be mounted, thereby facilitating the installation of this supplementary device.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model discloses a zinc pot zinc liquid replenishment device. When the servo motor is working, it drives the wire block to rise and fall, thereby causing the zinc rod to rise and fall. Since each group of zinc rods is close to the bottom of the pot in the initial state, when the electric heater is used to heat each group of zinc rods, the bottom of the zinc rods is eliminated at the same speed. Therefore, when the zinc rods move downward with the up and down movement of the wire block, each group of zinc rods can always be kept close to the bottom of the pot. The heated zinc liquid flows out through the discharge pipe to replenish the zinc pot. This replenishment device has a structure that can easily raise and lower the zinc rods and can easily keep the bottom of the core rods heated at close range, thereby achieving efficient replenishment of the core liquid.

A vertical plate 12 is welded to one end of the top of the bottom plate 1. A servo motor 13 is mounted on one end of the vertical plate 12 near the bottom via a fixed base. The output shaft of the servo motor 13 is connected to a lead screw 14. A lead screw block 16 is sleeved around the lead screw 14. A disc-shaped top plate 19 is welded to one end of the lead screw block 16. A pre-drilled hole 20 is provided at the top of the bottom plate 1, and a zinc rod 21 is placed inside the pre-drilled hole 20. A through groove 2 is provided at the top of the bottom plate 1 near the center. A first support plate 5 is provided at both ends of the bottom plate 1 near the through groove 2. A pot body 6 is connected to the top of the first support plate 5. An electric heater 9 is fixed to the outer wall of the pot body 6 by connecting bolts 8. An annular outer wall 23 is welded to the bottom of the disc-shaped top plate 19 near the edge. The bottom of the annular outer wall 23 is located outside the top of the pot body 6.

[0020] The bottom plate 1 has a second support plate 10 welded to both ends near the top of the bottom plate 1. The top of the second support plate 10 is connected to an annular limiting baffle 11, which is located around the annular outer wall 23.

[0021] In this embodiment, as shown... Figure 1 and Figure 4 As shown, the annular limiting baffle 11 facilitates the limiting and guiding function of the annular outer wall 23 during lifting and lowering.

[0022] The vertical plate 12 has a slide rail 15 near the center at one end, the end of the screw block 16 is located inside the slide rail 15, an extension block 17 is welded to one side of the top of the vertical plate 12, a bearing 18 is provided at the bottom of the extension block 17, and the top of the screw 14 is located inside the bearing 18.

[0023] In this embodiment, as shown... Figure 1-3 As shown, the limiting and guiding effect of the slide rail 15 on the lead block 16 and the limiting and guiding effect of the bearing 18 on the lead screw 14 can effectively improve the stability of the lead block 16 when moving up and down.

[0024] The thermostat 22 is fixed to one end of the upright plate 12 near the bottom by a connecting rod. The power output end of the thermostat 22 is electrically connected to the power input end of the electric heater 9 by a wire.

[0025] In this embodiment, as shown... Figure 1As shown, the heating temperature of the electric heater 9 can be easily controlled by controlling the temperature controller 22.

[0026] The base plate 1 has protrusions 3 welded to both ends near the bottom, and the bottom of the protrusions 3 has mounting holes 4 through them.

[0027] In this embodiment, as shown... Figure 1 As shown, external bolts pass through mounting holes 4 to facilitate the fixing of protrusion 3 to the external surface to be installed, thereby facilitating the installation of this supplementary device.

[0028] It should be noted that this utility model is a zinc pot zinc liquid replenishment device. During operation, external bolts pass through the mounting hole 4 to facilitate the fixing of the protrusion 3 to the external surface to be installed, thus facilitating the installation of this replenishment device. The through groove 2 is located on the upper side of the opening of the external zinc pot. The top of the zinc rod 21 is provided with a protrusion corresponding to the reserved hole 20, which is used to limit the vertical height of the zinc rod 21. When the servo motor 13 is working, it can easily drive the lead screw 14 to rotate, thereby causing the lead block 16 to move up and down along the slide rail 15, which in turn drives the disc-shaped top plate 19 and the zinc rod 21. As the zinc rods 21 move up and down, and each group of zinc rods 21 is initially close to the bottom of the pot body 6, the bottom of the zinc rods 21 is eliminated at the same speed when the electric heater 9 heats each group of zinc rods 21. Therefore, when the zinc rods 21 move down with the wire block 16, each group of zinc rods 21 can always be kept close to the bottom of the pot body 6. The heated zinc liquid flows out through the discharge pipe 7 to replenish the external zinc pot. This replenishment device has a structure that can easily raise and lower the zinc rods 21, and can easily heat the bottom of the core rod at close range, thereby achieving efficient replenishment of the core liquid.
