Description

Technical Field

[0001] This utility model relates to the technical field of diamond wire production equipment, and in particular to a stirring device for coating micro powder. Background Technology

[0002] Diamond wire is short for diamond cutting wire, also known as diamond cutting wire or diamond wire. Many hard materials in industry are cut using cutting steel wire or even higher-quality diamond wire, such as polycrystalline silicon wafers, monocrystalline silicon wafers, and ingots in the photovoltaic field. In diamond wire production lines, to electroplate the diamond wire busbar with diamond, the diamond micron powder needs to be chemically nickel-plated. This forms a nickel-phosphorus alloy coating on the surface of the diamond micron powder, making the surface conductive so that it can be adsorbed onto the diamond wire busbar through electroplating.

[0003] When nickel plating with diamond micropowder, the diamond micropowder, after pretreatment, is placed in a water bath containing a chemical plating solution. This water bath is then placed in a water bath tank and requires uniform stirring by a stirring paddle. Currently, the stirring method involves a worker holding a power tool with the paddle clamped to its output end, inserting it into the top opening of the water bath tank, and turning it on. This method requires the worker to hold the power tool for extended periods, resulting in significant manpower waste, fatigue, and a high risk of the paddle blades colliding with the inner wall of the tank, causing damage. Because stirring needs to be performed near the top of the water bath tank, commonly available stirring equipment is difficult to install properly.

[0004] Therefore, it is necessary to develop a stirring device for coating micro powder to address the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for coating micro powder, which is easy to install above a water bath and can stably and safely stir the mixture of diamond micro powder and chemical plating solution in the water bath material tank.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a stirring device for plating micronized powder, which is installed above a water bath for nickel plating of diamond micronized powder. It includes a frame, a sliding plate, a motor, a stirring paddle shaft, a vertical guide assembly, and a vertical drive assembly. The frame is a square frame formed by welding square tubing and is vertically installed on the wall or support inside the water bath. The vertical guide assembly is vertically mounted on the central longitudinal beam on the front of the frame. The sliding plate is guided and slidably connected to the frame via the vertical guide assembly. The motor is installed at the bottom of the sliding plate, and its vertically downward-facing output shaft is connected to the stirring paddle shaft. The stirring paddle shaft can extend downwards into the water bath material container. The vertical drive assembly is mounted on the frame and can drive the sliding plate to slide up and down along the vertical guide assembly.

[0008] The specially designed rack and thinner design make it easy to install on the wall next to the water bath, reducing the installation space requirements.

[0009] Furthermore, the vertical guide assembly includes a linear guide rail and a ball bearing slider. The linear guide rail is vertically fixed to the middle longitudinal beam of the frame by screws, and the ball bearing slider is slidably connected to the linear guide rail. The ball bearing slider is installed on the back of the slide plate.

[0010] Furthermore, it also includes a flange seat and a main pin. The bottom end of the slide plate is welded with a horizontally arranged support lug. The main body of the flange seat is an L-shaped plate seat. The motor head is installed downward in the mounting hole of the horizontal plate of the flange seat. A swing arm plate is horizontally welded to the outside of the vertical plate of the flange seat. The swing arm plate can be rotatably inserted into the support lug groove of the support lug and connected through the main pin.

[0011] Furthermore, it also includes a swing angle locking pin. The outer end of the support ear has two symmetrically arranged swing angle locking holes vertically, and the swing arm plate has a corresponding locking pin hole. The swing angle locking pin is inserted into either the swing angle locking hole or the locking pin hole of the swing arm plate to lock the working position or standby position of the stirring paddle shaft.

[0012] The unique sway design allows switching between the working and standby positions of the agitator shaft. In the working position, the agitator shaft and the water bath material tank overlap vertically. When not agitating, the agitator shaft and related components are offset to one side, making it easier for operators to remove the water bath material tank from the water bath.

[0013] Furthermore, the vertical drive assembly includes a rack, a gear, a bearing housing, a handwheel, and a locking member. The rack is located on the back side of one side of the slide plate, and a drive mounting plate is welded to the frame behind the rack mounting position. The output shaft of the handwheel is mounted to the front side wall of the drive mounting plate through the bearing housing. The end of the handwheel output shaft is coaxially keyed to the gear, and the gear meshes with the rack. The locking member can stop the gear.

[0014] Furthermore, the locking component includes a stop pawl, a torsion spring, and a support base. The root of the stop pawl is rotatably connected to the top of the support base via a rotating shaft, and the downward-facing tip of the stop pawl abuts against the teeth of the gear. The root of the support base is fixedly connected to the front side wall of the drive mounting plate. The torsion spring is sleeved on the rotating shaft and its two ends are connected to the stop pawl and the support base.

[0015] Furthermore, a release handle is fixedly connected to the root of the stop pawl, which faces upwards. Pulling the release handle can overcome the torsion spring's restoring force and cause the tip of the stop pawl to disengage from the gear.

[0016] Furthermore, the stirring paddle shaft is covered with a protective layer made of PP material.

[0017] Furthermore, a baffle is provided at the bottom of the flange seat, which can cover and seal the top opening of the water bath material tank.

[0018] While the stirring paddle shaft is being lowered into place, the baffle also covers and seals the top opening of the water bath material tank, eliminating the need for additional sealing operations.

[0019] Compared with the prior art, the advantages of the stirring device for coating micro powder of this utility model are as follows:

[0020] This utility model discloses a stirring device for coating micronized powder. By setting the frame as a square frame formed by welding square tubing, the installation space is compact, allowing for easy installation onto the wall or support inside the water bath tank via legs or hangers. The stirring paddle shaft's entry and exit from the tank is achieved by a sliding plate guided along the vertical guide assembly. Compared to manually supporting the electric tool for stirring, installing and supporting the motor via the sliding plate improves stirring stability and safety. This utility model's stirring device for coating micronized powder is easy to install above a water bath tank and can stably and safely stir the mixture of diamond micronized powder and chemical plating solution in the water bath material tank.

[0021] Furthermore, the main pin connects the swing arm plate and the support lugs, allowing the flange seat to rotate around the main pin, thus enabling the agitator shaft to switch between the working and standby positions. By adding a swing angle locking hole and a swing angle locking pin, a double-pin locking method is used to fix the angle of the swing arm plate, ensuring stable operation of the agitator shaft in the working position. A right-angle bend or hanging ring at the top of the swing angle locking pin facilitates easy insertion and removal by operators. Using a rack and pinion system to control the movement of the slide plate allows for precise control of the downward stroke, ensuring the required depth of entry into the water bath material tank is met. A handwheel drive gear facilitates manual movement of the slide plate, reducing equipment manufacturing costs. A pawl-type stop gear prevents the gear from rotating under its own weight. A release handle allows for quick unlocking of the gear lock, enabling rapid descent. Adding a PP protective layer to the shaft section and blades of the agitator shaft prevents corrosion from the chemical plating solution and reduces wear from the diamond powder. By adding the baffle, the top opening of the water bath material tank can be sealed after the stirring paddle shaft descends and enters the water bath material tank, thus preventing the mixture from splashing out during the stirring process.

[0028] The core of this invention is to provide a stirring device for coating micro powder, which is easy to install above a water bath and can stably and safely stir the mixture of diamond micro powder and chemical plating solution in the water bath material tank.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main structure of the stirring device for coating micro powder according to this utility model; Figure 2 This is a schematic diagram of the left side of the stirring device for coating micro powder according to this utility model; Figure 3 This is a side view of the gear and stop pawl components in this utility model. Figure 4 This is a top view schematic diagram of the mechanism at the position of the middle support ear of this utility model.

[0032] In one specific implementation, such as Figures 1-4 As shown, the stirring device for plating micro-powder of this utility model is installed above a water bath for nickel plating of diamond micro-powder. It includes a frame 1, a sliding plate 2, a motor 4, a stirring paddle shaft 5, a vertical guide assembly, and a vertical drive assembly. The frame 1 is a square frame formed by welding square tubes, with reinforcing square or rectangular tubes in the middle. The frame 1 is vertically installed on the wall or support inside the water bath, which is generally arranged against the wall or set on one side with a support for hanging objects. The vertical guide assembly is vertically installed on the middle longitudinal beam on the front of the frame 1. The middle longitudinal beam is a rectangular tube welded vertically in the middle part of the frame 1. The sliding plate 2 is guided and slidably connected to the frame 1 through the vertical guide assembly. The motor 4 is installed at the bottom of the sliding plate 2, and the vertically downward output shaft of the motor 4 is coaxially connected to the stirring paddle shaft 5. The bottom end of the stirring paddle shaft 5 is provided with stirring blades. As the sliding plate 2 moves vertically downward, the stirring paddle shaft 5 can penetrate downward into the water bath material tank 13. The vertical drive assembly is mounted on the frame 1 and can drive the slide plate 2 to slide up and down along the vertical guide assembly.

[0033] Specifically, it also includes a speed controller. The motor 4 is a speed-regulating motor, and the speed controller is electrically connected to the motor 4, enabling control of the output speed of the motor 4. This allows for convenient adjustment of the operating speed of the stirring paddle shaft 5.

[0034] By setting the frame 1 as a square frame formed by welding square tubes, the installation space is compact, and it is easy to install it onto the wall or bracket inside the water bath tank via support legs or hangers. The sliding plate 2 slides along the vertical guide assembly, realizing the inlet and outlet movements of the stirring paddle shaft 5. Compared with manually supporting the electric tool for stirring, installing and supporting the motor 4 via the sliding plate 2 improves the stability and safety of stirring. This utility model is a stirring device for coating micro powder, which is easy to install above the water bath tank and can stably and safely stir the mixture of diamond micro powder and chemical plating solution in the water bath material tank 13.

[0035] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the vertical guide assembly includes a linear guide rail 101 and ball sliders 204. The linear guide rail 101 is vertically fixed to the middle longitudinal beam of the frame 1 by screws. At least two ball sliders 204 are slidably connected to the linear guide rail 101 and are mounted on the back of the slide plate 2.

[0036] Specifically, the linear guide rails 101 can be two parallel lines, with two ball bearing sliders 204 connected to each linear guide rail 101, and four ball bearing sliders 204 mounted on the back of the slide plate 2.

[0037] Obviously, the vertical guide assembly can also use guide posts and guide sleeves for vertical guidance. Using two guide posts and four guide sleeves positioned between the back of the slide plate 2 and the frame 1 can also achieve relatively precise guidance. Similar simple replacement methods all fall within the protection scope of this utility model.

[0038] In one specific embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4 As shown, the stirring device for coating micro powder of this utility model also includes a flange seat 3 and a main pin shaft 11. A horizontally arranged support lug 202 is welded to the bottom end of the slide plate 2, and the roots of the two support lug plates are directly welded to the bottom end of the front side wall of the slide plate 2. The main body of the flange seat 3 is an L-shaped plate seat. The motor 4 is installed downwards in the mounting hole of the horizontal plate of the flange seat 3. A swing arm plate 301 is horizontally welded to the outer side of the vertical plate of the flange seat 3. The swing arm plate 301 can be rotatably inserted into the support lug groove of the support lug 202 and connected through the main pin shaft 11.

[0039] Specifically, such as Figure 2As shown, a supporting stiffener is provided between the outer wall of the rocker arm plate 301 and the vertical plate of the flange seat 3. The supporting stiffener is a triangular tie plate.

[0040] Specifically, such as Figure 2 and Figure 4 As shown, the stirring device for coating micro powder of this utility model also includes a swing angle locking pin 12. Two symmetrically arranged swing angle locking holes 2021 are vertically formed on the outer end of the support ear 202, i.e., they are formed on the support ear plate. The swing arm plate 301 has corresponding locking pin holes, meaning the locking pin holes can move to a coaxial position with the swing angle locking holes 2021. The swing angle locking pin 12 is inserted into either the swing angle locking hole 2021 or the locking pin hole of the swing arm plate 301 to lock the stirring paddle shaft 5 in its working or standby position.

[0041] Specifically, such as Figure 2 and Figure 4 As shown, the top of the sway pin 12 has a right-angle bend or a hanging ring, which makes it easy for operators to grab, pull out, and insert the pin.

[0042] The main pin 11 connects the swing arm plate 301 and the lug 202, enabling the flange seat 3 to rotate around the main pin 11, thus allowing the agitator shaft 5 to switch between the working position and the standby position. By adding a swing angle locking hole 2021 and a swing angle locking pin 12, the angle of the swing arm plate 301 is fixed using a double-pin locking method, ensuring stable operation of the agitator shaft 5 in the working position. A right-angle bend or hanging ring is provided at the top of the swing angle locking pin 12 for easy insertion and removal by operators.

[0043] In one specific embodiment of this utility model, such as Figures 1-3 As shown, the vertical drive assembly includes a rack 203, a gear 6, a bearing seat 7, a handwheel 8, and a locking component. The rack 203 is screwed onto the back of one side of the slide plate 2. To increase the height of the slide plate 2, the side where the rack 203 is mounted extends downwards by a certain length. A drive mounting plate 102 is welded to the rear of the rack 203 mounting position on the frame 1. The bottom end of the drive mounting plate 102 is welded to the bottom crossbeam tube of the frame 1, and the top end is welded to the crossbeam tube in the middle of the frame 1. The output shaft of the handwheel 8 is mounted to the front wall of the drive mounting plate 102 via the bearing seat 7, which is screwed onto the front wall of the drive mounting plate 102. The output shaft of the handwheel 8 is coaxially keyed to the gear 6, which meshes with the rack 203. The locking component can stop the gear 6.

[0044] Specifically, such as Figure 1 As shown, multiple weight-reducing holes 201 are arranged at intervals between the mounting side of the rack 203 and the main body plate of the slide plate 2.

[0045] Specifically, the locking component includes a stop pawl 9, a torsion spring, and a support base 10. The root of the stop pawl 9 is rotatably connected to the top of the support base 10 via a rotating shaft, which is clearance-fitted into the shaft hole at the top of the support base 10. The downward-facing tip of the stop pawl 9 abuts against the teeth of the gear 6. The root of the support base 10 is directly welded to the front sidewall of the drive mounting plate 102. The torsion spring is sleeved on the rotating shaft and its two ends are connected to the stop pawl 9 and the support base 10. The restoring force of the torsion spring causes the tip of the stop pawl 9 to press against the gear 6.

[0046] Obviously, the locking component can also lock the gear 6 using a locking pin method. That is, multiple circumferential through holes are evenly distributed around the end face of the gear 6, and a locking pin seat is added to the front side wall of the drive mounting plate 102. The gear 6 is locked by inserting the locking pin into the through holes of different positions. Similar simple modifications all fall within the protection scope of this utility model.

[0047] Specifically, such as Figure 1 and Figure 3 As shown, a release handle 901 is fixedly connected to the base of the stop pawl 9, with the base facing upwards. The release handle 901 is an L-shaped thin rod structure, with its bottom end directly welded to the base of the stop pawl 9 and its top end having a bent portion. Pulling the release handle 901 can overcome the torsion spring's restoring force, causing the tip of the stop pawl 9 to disengage from the gear 6.

[0048] By employing a rack and pinion mechanism to control the movement of the slide plate 2, the downward stroke can be precisely controlled, ensuring that the depth of entry into the water bath material tank 13 meets the requirements. The handwheel 8 drives the gear 6, facilitating manual movement of the slide plate 2 and reducing equipment processing costs. The use of a pawl 9 to stop the gear 6 prevents it from rotating under its own weight. The release handle 901 allows for quick unlocking of the gear, enabling rapid descent.

[0049] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the impeller shaft 5 is covered with a protective layer made of PP material. The protective layer is made of high-density PP plastic.

[0050] By adding a PP protective layer to the shaft section and blades of the agitator shaft 5, the corrosion of the agitator shaft 5 by the chemical plating solution can be prevented, and the wear of the diamond powder can also be reduced.

[0051] In one specific embodiment of this utility model, a baffle is also provided at the bottom of the flange seat 3, which can cover and seal the top opening of the water bath material tank 13. The baffle is made of plastic sheet and is installed on the bottom surface of the horizontal plate of the flange seat 3 by screws. The baffle has a clearance hole at the position of the stirring paddle shaft 5.

[0052] By adding the baffle, the top opening of the water bath material tank 13 can be sealed after the stirring paddle shaft 5 enters the water bath material tank 13, thus preventing the mixture from splashing out during the stirring process.

[0053] The working process of this utility model's stirring device for coating micro powder is as follows: Before each stirring, first determine whether the stirring paddle shaft 5 is in the working position, i.e., whether it is directly above the water bath material tank 13. If not, re-insert the swing angle locking pin 12 and pull the swing arm plate 301 back to the angle corresponding to the working position. When the slide plate 2 moves downward, pulling the release handle 901 can overcome the torsion spring's reset force, causing the tip of the stop pawl 9 to disengage from the gear 6. Under the self-weight of the slide plate 2 and its components, the gear 6 can rotate rapidly. By holding the handle of the handwheel 8, the rotation speed can be easily controlled, allowing the stirring paddle shaft 5 to quickly move into the water bath material tank 13. After moving into position, release the release handle 901 to reset the stop pawl 9 to the engagement position of the gear 6, completing the working position locking. At this time, the baffle simultaneously closes the top opening of the water bath material tank 13. Turn on the motor 4, and at the set speed, the motor 4 drives the stirring paddle shaft 5 to uniformly stir the diamond micro powder and chemical plating solution in the water bath material tank 13. After stirring is completed, stop the motor 4 and raise the stirring paddle shaft 5. Since the stop pawl 9 is already in contact with the gear 6, it creates a downward anti-reverse effect. Therefore, every time the handwheel 8 rotates and the slide plate 2 moves upward, the stop pawl 9 will engage with the gear 6, preventing the agitator shaft 5 from suddenly descending without resistance and thus preventing a safety accident. After the agitator shaft 5 is raised, the swing angle locking pin 12 is removed, the flange seat 3 and its components are rotated aside, and the swing angle locking pin 12 is reinserted. This makes it easier for operators to remove the water bath material tank 13 from the water bath.

[0054] In summary, this utility model's stirring device for coating micro powder, by setting the frame 1 as a square frame formed by welding square tubes, has a compact installation space and is easy to install onto the wall or bracket inside the water bath tank via support legs or hangers; the sliding plate 2 slides along the vertical guide assembly, realizing the infeed and outfeed actions of the stirring paddle shaft 5. Compared to manually supporting the electric tool for stirring, installing and supporting the motor 4 via the sliding plate 2 improves the stirring stability and safety. This utility model's stirring device for coating micro powder is easy to install above the water bath tank and can stably and safely stir the mixture of diamond micro powder and chemical plating solution in the water bath material tank 13. Furthermore, by connecting the swing arm plate 301 and the support lug 202 via the main pin 11, the flange seat 3 can rotate around the main pin 11, thereby enabling the agitator shaft 5 to switch between the working position and the standby position. By adding a swing angle locking hole 2021 and a swing angle locking pin 12, the angle of the swing arm plate 301 is fixed using a double-pin locking method, ensuring stable operation of the agitator shaft 5 in the working position. A right-angle bend or hanging ring is provided at the top of the swing angle locking pin 12 for easy insertion and removal by operators. The movement of the slide plate 2 is controlled by a gear and rack system, allowing precise control of the downward stroke to ensure the required depth of entry into the water bath material tank 13. A handwheel 8 drives the gear 6, facilitating manual movement of the slide plate 2 and reducing equipment processing costs. A stop pawl 9 stops the gear 6, preventing it from rotating under its own weight. A release handle 901 allows for quick unlocking of the gear, enabling rapid descent. By adding a PP protective layer to the shaft section and blades of the agitator shaft 5, corrosion of the agitator shaft 5 by the chemical plating solution can be prevented, and wear of the diamond powder can also be reduced. By adding the baffle, the top opening of the water bath material tank 13 can be sealed after the agitator shaft 5 enters the water bath material tank 13, preventing the mixture from splashing out during the stirring process.
