Description

TECHNICAL FIELD

[0001] The utility model relates to electroplating technical field, concretely relates to electroplating equipment apron structure and electroplating equipment. BACKGROUND

[0002] In the electroplating process, when the current density is too high, the electroplated part will produce "edge effect", that is, the current density increases significantly at the edge or protruding part of the workpiece, resulting in the thickness of the coating in these areas being significantly higher than that in other areas. This phenomenon is mainly caused by uneven electric field distribution and electrochemical mass transfer difference.

[0003] At present, the electroplating equipment usually uses a fixed-size apron to shield the edge area of the electroplated part to suppress the current density, thereby reducing the "edge effect" and ensuring the uniformity of the coating thickness. In order to meet the use needs of smaller size electroplated parts, a larger shielding area apron needs to be set, that is, the size of the apron is larger. However, a larger size apron will occupy the space inside the electroplating equipment. SUMMARY

[0004] Therefore, the utility model provides an electroplating equipment apron structure and electroplating equipment to solve the problem that smaller size electroplated parts need to use a larger shielding area apron, resulting in the apron occupying the space inside the electroplating equipment.

[0005] In a first aspect, the utility model provides an electroplating equipment apron structure, comprising:

[0006] An apron frame enclosing a containing space;

[0007] A first apron movably arranged in the containing space of the apron frame;

[0008] A second apron slidingly connected with the first apron and located in the containing space;

[0009] The first apron is provided with a driving part, and the driving part is connected with the apron frame and the second apron respectively. By pushing the first apron, the driving part moves relative to the apron frame, and the second apron moves relative to the first apron.

[0010] Advantages: The utility model supports the first apron and the second apron through the apron frame, and uses the slidingly connected first apron and the second apron to shield the edge area of the electroplated part. The first apron and the second apron slide relative to each other and have different sliding strokes, forming a gradually expanding misaligned shielding area, which can meet the use needs of electroplated parts of various sizes and has a wide range of applications. Moreover, the first apron and the second apron can be stacked together, occupying less space.

[0011] In an alternative embodiment, the shutter frame comprises a surrounding plate, the surrounding plate surrounds the containing space, at least one side of the surrounding plate is provided with a first gear rack, the second shutter is provided with a second gear rack corresponding to the first gear rack on the side close to the first shutter, and the driving part is a gear wheel, the gear wheel is engaged with the first gear rack and the second gear rack respectively.

[0012] Beneficial effects: by pushing the first shutter, the gear wheel on the first shutter rotates under the action of the first gear rack and the second gear rack, and the first gear rack and the second gear rack move in opposite directions. The first gear rack is fixed on the surrounding plate, and the second gear rack is fixed on the second shutter, so that the first shutter moves relative to the surrounding plate while the second shutter moves relative to the surrounding plate with a greater stroke, thereby causing the first shutter and the second shutter to move out of position relative to the surrounding plate, forming a gradually expanding shielding area to meet the use requirements of different sizes of electroplated parts.

[0013] In an alternative embodiment, the opposite sides of the surrounding plate are respectively provided with the first gear rack, the second shutter is provided with two second gear racks corresponding to the first gear rack, and the driving part is a pair of gear wheels, the pair of gear wheels are arranged at one end of the first shutter close to the inner side of the containing space, and the pair of gear wheels are engaged with the corresponding first gear rack and the second gear rack respectively.

[0014] Beneficial effects: by arranging the first gear rack on the opposite sides of the surrounding plate and corresponding arranging the two second gear racks and the two gear wheels, a structure with two end supports is formed, which is beneficial to improving the movement stability of the first shutter and the second shutter, thereby improving the service life of the shutter structure of the electroplating equipment.

[0015] In an alternative embodiment, the side of the first shutter close to the second shutter is provided with a sliding part, and the sliding part is in sliding connection with the second gear rack.

[0016] Beneficial effects: the first shutter is in sliding connection with the second gear rack through the sliding part, which can guide and limit the first shutter and the second shutter through the sliding part, further improving the movement stability of the first shutter and the second shutter.

[0017] In an alternative embodiment, the side of the second gear rack away from the first gear rack is provided with a sliding rail, and the sliding part is a sliding block, the sliding block is in sliding cooperation with the sliding rail.

[0018] Beneficial effects: the sliding block is fixed on the first shutter, the second gear rack is fixed on the second shutter, and the sliding block is in sliding connection with the first shutter and the second shutter by sliding in the sliding rail, thereby realizing the guiding and limiting effects.

[0019] In an alternative embodiment, the moving stroke of the second shutter is greater than the moving stroke of the first shutter.

[0020] Beneficial effects: The second shielding plate has a greater travel distance than the first shielding plate, causing the first and second shielding plates to move out of alignment with the surrounding plate. The second shielding plate gradually exceeds the coverage area of ​​the first shielding plate. The area of ​​the second shielding plate that exceeds the coverage area of ​​the first shielding plate and the area where the first shielding plate is located together form a shielding surface to shield electroplated parts of different sizes.

[0021] In one alternative implementation, the travel distance of the second baffle is twice that of the first baffle.

[0022] Beneficial effects: Since the gear is mounted on the first shielding plate, when the gear rotates, the rotational stroke of the gear and the first rack is the moving stroke of the first shielding plate, and the relative stroke of the first rack and the second rack is the moving stroke of the second shielding plate. Setting the moving stroke of the second shielding plate to twice that of the first shielding plate makes it easier to accurately control the shielding area of ​​the first and second shielding plates, thus facilitating the rapid shielding of electroplated parts of different sizes.

[0023] In one alternative embodiment, a push rod is further included, which passes through one side of the enclosure and has one end connected to the first cover plate for pushing the first cover plate.

[0024] Beneficial effect: By connecting and setting a push rod on one side of the first cover, it is easy to push the first cover by the push rod, which makes it convenient to use.

[0025] In one optional embodiment, a guide sleeve is provided on one side of the enclosure to connect the inner and outer sides of the accommodating space, and the push rod passes through the guide sleeve.

[0026] Beneficial effects: The guide sleeve is used to guide and limit the push rod, which helps to improve the motion stability between the first and second baffles.

[0027] Secondly, this utility model also provides an electroplating device, comprising:

[0028] Clamps suitable for clamping electroplated parts;

[0029] In the above-described electroplating equipment shielding structure, at least one of the first shielding plate and the second shielding plate is capable of shielding the edge area of ​​the electroplated part.

[0030] Beneficial effects: Since the electroplating equipment includes an electroplating equipment shielding structure, it has the same effect as the electroplating equipment shielding structure, so it will not be elaborated here. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0041] According to embodiments of the present invention, on the one hand, such as Figure 1As shown, a shielding structure for electroplating equipment is provided, mainly including: a shielding frame 1, a first shielding plate 2, and a second shielding plate 3. The shielding frame 1 encloses an accommodating space. The first shielding plate 2 is movably disposed within the accommodating space of the shielding frame 1. The second shielding plate 3 is slidably connected to the first shielding plate 2 and located within the accommodating space. The first shielding plate 2 is provided with a driving part 201, which is connected to both the shielding frame 1 and the second shielding plate 3. By pushing the first shielding plate 2, the driving part 201 moves relative to the shielding frame 1, thereby causing the second shielding plate 3 to move relative to the first shielding plate 2.

[0042] Therefore, the electroplating equipment shielding structure provided in this embodiment of the utility model supports the first shielding plate 2 and the second shielding plate 3 through the shielding plate frame 1. The first shielding plate 2 and the second shielding plate 3, which are slidably connected, shield the edge area of ​​the electroplated part 6. The first shielding plate 2 and the second shielding plate 3 slide relative to each other and have different sliding strokes, forming a gradually expanding staggered shielding area, which can meet the usage requirements of electroplated parts 6 of various sizes and has a wide range of applications. Moreover, the first shielding plate 2 and the second shielding plate 3 can be stacked together, occupying less space.

[0043] Specifically, in the initial state, the first shield 2 and the second shield 3 are stacked together, which can meet the usage requirements of larger electroplated parts 6. When the first shield 2 is pushed, under the action of the drive unit 201, the first shield 2 and the second shield 3 move relative to the shield frame 1 respectively, and the moving stroke of the second shield 3 is greater than the moving stroke of the first shield 2, thereby gradually expanding the coverage area of ​​the first shield 2 and the second shield 3. When the first shield 2 moves to its maximum stroke, the ends of the first shield 2 and the second shield 3 connect to form the maximum coverage area, thereby meeting the usage requirements of smaller electroplated parts 6. When the first shield 2 and the second shield 3 are not used to shield the electroplated parts 6, pushing the first shield 2 back to the initial state, the first shield 2 and the second shield 3 are stacked together, which does not occupy the electroplating space of the electroplating equipment.

[0044] In addition, the movement of the second shield 3 is greater than that of the first shield 2, causing the first shield 2 and the second shield 3 to move out of alignment with the enclosure 101. The second shield 3 gradually exceeds the coverage area of ​​the first shield 2. The area of ​​the second shield 3 that exceeds the coverage area of ​​the first shield 2 and the area where the first shield 2 is located together form a shielding surface to shield electroplated parts 6 of different sizes.

[0045] Specifically, the first shield 2 and the second shield 3 can be made of insulating board, such as polyvinyl chloride board, polyethylene board, etc., which has good acid and alkali resistance and corrosion resistance. Multiple through holes can also be provided on the first shield 2 and the second shield 3 to adjust the current distribution and electroplating solution flow.

[0046] In one embodiment, such as Figure 2As shown, the cover frame 1 includes a surrounding plate 101, which encloses an accommodating space. At least one side of the surrounding plate 101 is provided with a first rack 102. The side of the second cover 3 closest to the first cover 2 is provided with a second rack 301 opposite to the first rack 102. The drive unit 201 is a gear, which meshes with both the first rack 102 and the second rack 301.

[0047] By pushing the first shield 2, the gears on the first shield 2 rotate under the action of the first rack 102 and the second rack 301, causing the first rack 102 and the second rack 301 to move in opposite directions. The first rack 102 is fixed to the enclosure 101, and the second rack 301 is fixed to the second shield 3, so that while the first shield 2 moves relative to the enclosure 101, the second shield 3 moves relative to the enclosure 101 with a larger stroke, thereby causing the first shield 2 and the second shield 3 to move in a staggered manner relative to the enclosure 101, forming a gradually expanding shielding area to meet the usage requirements of electroplated parts 6 of different sizes.

[0048] Specifically, the first rack 102 is fixed to the inner wall of the enclosure 101, for example, by fasteners. Fasteners can be screws, bolts, etc. The gear is rotatably mounted on the first cover plate 2, for example, by a bearing. The second rack 301 is fixed to the second cover plate 3, for example, by fasteners. The opposite sides of the gear mesh with the first rack 102 and the second rack 301, respectively.

[0049] Furthermore, in one embodiment, such as Figure 2 As shown, the enclosure 101 has first racks 102 on opposite sides. The second cover 3 has two corresponding second racks 301. The drive unit 201 is a pair of gears, which are spaced apart at one end of the first cover 2 near the inner side of the receiving space. The pair of gears mesh with the corresponding first racks 102 and second racks 301 respectively.

[0050] First racks 102 are respectively provided on opposite sides of the enclosure 101, and two second racks 301 and two gears are respectively provided to form a structure supported at both ends, which helps to improve the movement stability of the first shield 2 and the second shield 3, thereby improving the service life of the shield structure of the electroplating equipment.

[0051] Furthermore, in one embodiment, the first shield 2 is disposed above the second shield 3, and a pair of gears are disposed on opposite sides of the bottom surface of the first shield 2, close to the surrounding plate 101. The electroplated part 6 is located below the second shield 3. The opposite sides of the bottom surface of the first shield 2 are respectively provided with clearance grooves to avoid the first rack 102 and / or the second rack 301.

[0052] In one embodiment, such as Figure 3 and Figure 4As shown, the first cover plate 2 has a sliding part 202 on the side near the second cover plate 3, and the sliding part 202 is slidably connected to the second rack 301. The first cover plate 2 is slidably connected to the second rack 301 through the sliding part 202, which can guide and limit the first cover plate 2 and the second cover plate 3, further improving the movement stability of the first cover plate 2 and the second cover plate 3.

[0053] Furthermore, in one embodiment, such as Figure 4 As shown, the second rack 301 has a slide rail 302 on the side opposite to the first rack 102, and the sliding part 202 is a slider, which slides in conjunction with the slide rail 302. The slider is fixed on the first cover plate 2, the second rack 301 is fixed on the second cover plate 3, and the slider slides in the slide rail 302 to achieve a sliding connection between the first cover plate 2 and the second cover plate 3, thereby achieving the guiding and limiting functions.

[0054] Specifically, the first cover plate 2 has a mounting groove between a pair of gears, and the slider is fixed in the mounting groove. The slider protrudes from the bottom surface of the first cover plate 2, and one side of the slider extends toward the second rack 301 and is slidably connected to the slide rail 302.

[0055] Furthermore, in one embodiment, the travel distance of the second shield 3 is twice the travel distance of the first shield 2. Since the gear is mounted on the first shield 2, when the gear rotates, the rotational travel distance between the gear and the first rack 102 is the travel distance of the first shield 2, and the relative travel distance between the first rack 102 and the second rack 301 is the travel distance of the second shield 3. Setting the travel distance of the second shield 3 to twice that of the first shield 2 facilitates precise control of the shielding area of ​​the first shield 2 and the second shield 3, thereby enabling rapid shielding of electroplated parts 6 of different sizes.

[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the electroplating equipment's shielding structure also includes a push rod 4, which passes through one side of the enclosure 101. One end of the push rod 4 is connected to the first shielding plate 2 for pushing the first shielding plate 2. By connecting the push rod 4 to one side of the first shielding plate 2, it is convenient to push the first shielding plate 2, making it easy to use.

[0057] Furthermore, in one embodiment, such as Figure 2 As shown, a guide sleeve 103 is provided on one side of the enclosure 101, connecting the inner and outer sides of the receiving space, and the push rod 4 passes through the guide sleeve 103. The guide sleeve 103 is used to guide and limit the push rod 4, which helps to improve the movement stability between the first cover plate 2 and the second cover plate 3. The second cover plate 3 moves away from the push rod 4.

[0058] It should be noted that this embodiment of the invention does not limit the number of push rods 4; one, two, or more can be selected as needed. The same number of guide sleeves 103 are correspondingly provided on the enclosure 101. For example, as... Figure 1 As shown, two push rods 4 are provided, spaced apart on the same side of the enclosure 101.

[0059] According to an embodiment of the present invention, on the other hand, as... Figure 5 As shown, an electroplating apparatus is also provided, mainly comprising: a clamp 5 and an electroplating apparatus shielding structure; the clamp 5 is adapted to clamp the electroplated part 6. At least one of the first shielding plate 2 and the second shielding plate 3 is capable of shielding the edge area of ​​the electroplated part 6.

[0060] Since the electroplating equipment includes a shielding structure that has the same effect as the shielding structure, it will not be elaborated on here.

[0061] Specifically, such as Figure 5 As shown, the clamp 5 is located on the outside of the shielding frame, and the electroplated part 6 is located below the shielding frame and is shielded by the first shielding plate 2 and the second shielding plate 3.

[0062] To achieve the basic functions of the electroplating equipment, the electroplating equipment in this embodiment may also include other necessary modules or components, such as a housing and an electroplating tank. It should be noted that any suitable existing structure can be selected from the other necessary modules or components included in the electroplating equipment. To clearly and concisely illustrate the technical solution provided in this embodiment, the above-mentioned parts will not be repeated here, and the accompanying drawings have also been simplified accordingly. However, it should be understood that the scope of this utility model is not limited thereto.

[0063] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
