Description

Technical Field

[0001] This application relates to the field of electroplating technology, and in particular to a pressing device, a hanger, and an electroplating production line. Background Technology

[0002] In the field of vertical electroplating technology, the workpiece to be plated (e.g., a circuit board to be plated) is fixed on a hanger in the electroplating production line. The hanger includes an upper clamp and a lower clamp arranged opposite each other. The workpiece to be plated is fixed between the upper clamp and the lower clamp. The upper clamp and the lower clamp are spaced apart in the vertical direction. The upper clamp clamps the upper end of the workpiece to be plated along the thickness direction of the workpiece to be plated, and the lower clamp clamps the lower end of the workpiece to be plated along the thickness direction of the workpiece to be plated. This realizes the clamping of the workpiece to be plated by the electroplating equipment.

[0003] However, with traditional electroplating equipment, the surface of the workpiece to be plated will warp or wrinkle, which will affect the flatness of the workpiece surface and ultimately affect the electroplating quality due to the low flatness. Utility Model Content

[0004] One of the technical problems addressed by this application is how to improve the electroplating quality of workpieces to be plated.

[0005] A clamping device is used in conjunction with a clamping mechanism, the clamping mechanism comprising a first clamp and a second clamp spaced apart and used to clamp opposite ends of a workpiece to be plated, characterized in that the clamping device comprises:

[0006] Load-bearing components;

[0007] A drive mechanism, wherein the drive mechanism is disposed on the support member; and

[0008] A clamping mechanism is provided on the driving mechanism. The driving mechanism is used to drive the clamping mechanism to move closer to or away from the first clamp. The clamping mechanism is used to press against the first clamp so that the first clamp can move away from the second clamp by a preset distance.

[0009] In one embodiment, the clamping mechanism includes a connecting unit and an elastic unit. The connecting unit is connected to the driving mechanism, and the elastic unit is disposed on the connecting unit. The elastic unit is elastic and is used to apply a force to the first clamp.

[0010] In one embodiment, the elastic unit includes an elastic element and an abutment element, the abutment element being slidably connected to the connecting unit and capable of protruding relative to the connecting unit, the elastic element abutting between the abutment element and the connecting unit.

[0011] In one embodiment, the connecting unit has a sliding hole, the abutting member slides in the sliding hole, and the elastic member is housed in the sliding hole.

[0012] In one embodiment, at least one of the following schemes is also included:

[0013] The abutting member includes a first abutting section and a second abutting section connected to each other. The first abutting section is used to contact the first clamp. The second abutting section protrudes from the end face of the first abutting section. The end face includes a stepped surface surrounding the second abutting section. The elastic member is sleeved on the second abutting section and abuts against the stepped surface.

[0014] The elastic element includes a spring;

[0015] The connecting unit includes a first connector and a second connector. The first connector is connected to the driving mechanism. The second connector protrudes from the surface of the first connector facing the carrier and has a higher flexibility than the first connector. The elastic unit is disposed on the second connector.

[0016] In one embodiment, the clamping mechanism further includes a first sensor disposed on the connecting unit and / or the elastic unit and used to send feedback information to control the movement of the clamping mechanism.

[0017] In one embodiment, the driving mechanism includes a driving cylinder, the cylinder barrel of which is fixed to the support member, and the piston rod of which is connected to the pressing mechanism.

[0018] In one embodiment, a transfer mechanism is also included, the transfer mechanism including a transferor that drives the carrier to move closer to or away from the first clamp so that the clamping mechanism can contact the first clamp.

[0019] In one embodiment, both the clamping mechanism and the carrier move in a linear motion and their directions of motion are perpendicular to each other;

[0020] The transfer mechanism also includes a second sensor, which is disposed on the carrier and used to send feedback information to control the movement of the carrier;

[0021] The transfer device includes a transfer cylinder, and the piston rod of the transfer cylinder is connected to the carrier.

[0022] A clamping device includes a clamping mechanism and a pressing device as described in any one of the above descriptions. The clamping mechanism includes a support member, a first clamp, and a second clamp. The first clamp and the second clamp are disposed on the support member and are used to clamp the workpiece to be plated. The pressing device is capable of contacting the first clamp. The first clamp and the second clamp are arranged at intervals in a vertical direction, and the second clamp is located above the first clamp.

[0023] An electroplating production line includes the aforementioned rack.

[0024] One technical effect of one embodiment of this application is that, given that the clamping device is used in conjunction with the clamping mechanism, when the first clamp moves closer to the second clamp due to the opening force, when the clamping mechanism clamps the next workpiece to be electroplated, the clamping mechanism can apply a force to the first clamp, thereby driving the first clamp away from the second clamp by a preset distance. This reasonably increases the distance between the first and second clamps. For the workpiece to be electroplated clamped between the first and second clamps, the first and second clamps can form a certain amount of tension on the workpiece, ensuring good tension under reasonable tension. This effectively prevents warping or wrinkling of the workpiece surface due to poor tension, thereby improving the flatness of the workpiece surface and ultimately improving the electroplating quality. Furthermore, the flat surface of the workpiece will not collide with other components of the electroplating production line, effectively preventing damage to the workpiece or equipment malfunction.

Detailed Implementation

[0035] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0037] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0041] See Figure 1 , Figure 2 and Figure 3An embodiment of this application provides a mounting fixture 10 including a clamping mechanism 11 and a pressing device 12. The clamping mechanism 11 is used to clamp a plate-shaped workpiece to be plated, such as a PCB substrate. Some PCB substrates have a small thickness, for example, the thickness of the PCB substrate can be 0.05mm to 1.6mm. The clamping mechanism 11 includes a first clamp 11a, a second clamp 11b, and a support member 11c. The first clamp 11a and the second clamp 11b are spaced apart on the support member 11c, and the support member 11c is the mounting carrier for the first clamp 11a and the second clamp 11b. For example, the first clamp 11a and the second clamp 11b can be spaced apart in the vertical direction, with the second clamp 11b located above the first clamp 11a. The second clamp 11b can clamp the upper end of the workpiece to be plated along the thickness direction, and the first clamp 11a can clamp the lower end of the workpiece to be plated along the thickness direction. This allows the workpiece to be plated to extend vertically and be clamped on the clamping mechanism 11. In this case, the first clamp 11a can be understood as the lower clamp, and the second clamp 11b as the upper clamp. After the clamping mechanism 11 has clamped the workpiece to be plated, it can be electroplated on the electroplating production line. In other embodiments, the workpiece to be plated can also be other thicker plate-like structures fixed on the hanger 10 in the same way as described in the above embodiments, and will not be repeated here.

[0042] See Figure 1 , Figure 2 and Figure 3 The clamping device 12 includes a support member 12a, a drive mechanism 12b, and a clamping mechanism 12c. The drive mechanism 12b is mounted on the support member 12a, and the clamping mechanism 12c is mounted on the drive mechanism 12b. The drive mechanism 12b drives the clamping mechanism 12c to move closer to or further away from the first clamp 11a. The clamping mechanism 12c presses against the first clamp 11a, thereby allowing the first clamp 11a to move a predetermined distance away from the second clamp 11b. When the first clamp 11a is located below the second clamp 11b, the clamping mechanism 12c can drive the first clamp 11a downwards a predetermined distance, thereby reasonably increasing the vertical distance between the first clamp 11a and the second clamp 11b.

[0043] If the clamping device 12 is not provided on the hanger 10, when the lower first clamp 11a is opened to unload the electroplated workpiece, the lower first clamp 11a will be displaced upwards under the opening force, thus reducing the vertical distance between the first clamp 11a and the second clamp 11b. When clamping the next workpiece to be electroplated via the clamping mechanism 11, the reduced distance between the first clamp 11a and the second clamp 11b reduces the vertical tension of the first clamp 11a and the second clamp 11b on the workpiece. This affects the tensioning effect of the first clamp 11a and the second clamp 11b on the workpiece, causing warping or wrinkling on the surface of the workpiece, which in turn affects the flatness of the plate-shaped workpiece surface, ultimately affecting the electroplating quality due to lower flatness. It is understandable that during the electroplating process, an uneven surface of the workpiece increases the probability of collision with other components of the electroplating production line, causing damage to the workpiece or equipment malfunction.

[0044] See Figure 1 , Figure 2 and Figure 3 Regarding the hanger 10 in the above embodiment, given the presence of the clamping device 12, when the first clamp 11a located below has a certain upward displacement due to the opening force, when the clamping mechanism 11 clamps the next workpiece to be electroplated, the clamping mechanism 12c can apply a force to the first clamp 11a, thereby driving the first clamp 11a downward away from the second clamp 11b by a preset distance. This will reasonably increase the distance between the first clamp 11a and the second clamp 11b. For the workpiece to be electroplated clamped between the first clamp 11a and the second clamp 11b, the first clamp 11a and the second clamp 11b can form a certain amount of tension in the vertical direction, so that the workpiece to be electroplated has a good tension effect under the action of reasonable tension. This effectively avoids warping or wrinkling of the surface of the workpiece to be electroplated due to poor tension, thereby improving the flatness of the surface of the workpiece to be electroplated, and ultimately improving the electroplating quality of the workpiece to be electroplated, ensuring that the electroplating quality of the workpiece to be electroplated meets the requirements. During the electroplating process, the flat surface of the workpiece to be plated will not collide with other parts of the electroplating production line, thus effectively avoiding damage to the workpiece or equipment failure.

[0045] It is understandable that when tensioning of the workpiece to be plated is required, the drive mechanism 12b can drive the clamping mechanism 12c to move closer to the first clamp 11a until it contacts the first clamp 11a, thereby applying downward pressure to the first clamp 11a. When the clamping mechanism 11 stops working, the drive mechanism 12b can drive the clamping mechanism 12c to move away from the first clamp 11a, causing the clamping mechanism 12c to disengage from the first clamp 11a.

[0046] See Figure 4 , Figure 5 and Figure 6 In some embodiments, the clamping mechanism 12c includes a connecting unit 100 and an elastic unit 200. The connecting unit 100 is connected to the driving mechanism 12b, and the elastic unit 200 is disposed on the connecting unit 100. The elastic unit 200 is elastic and applies a force to the first clamp 11a by contacting it. Because the elastic unit 200 is elastic, during the contact between the elastic unit 200 and the first clamp 11a, the elastic unit 200 can absorb the impact energy generated by the collision with the first clamp 11a due to its own elasticity, thus preventing damage to the first clamp 11a and the clamping mechanism 12c. Multiple elastic units 200 can be arranged at intervals on the connecting unit 100, allowing them to absorb more impact energy.

[0047] See Figure 7 , Figure 8 and Figure 9 In some embodiments, the elastic unit 200 includes an elastic element 210 and an abutment element 220. The abutment element 220 is slidably connected to the connecting unit 100, and the elastic element 210 abuts against the connecting unit 100. The abutment element 220 can protrude relative to the connecting unit 100, so that the abutment element 220 contacts the first clamp 11a and applies a force to the first clamp 11a. During the contact between the abutment element 220 and the first clamp 11a, the abutment element 220 can slide relative to the connecting unit 100 against the elastic force of the elastic element 210, thereby allowing the elastic element 210 to absorb the impact energy between the abutment element 220 and the first clamp 11a, preventing damage to the first clamp 11a and the abutment element 220. The elastic element 210 may include a spring or an elastic block, etc.

[0048] See Figure 7 , Figure 8 and Figure 9In some embodiments, the connecting unit 100 has a sliding hole 121, the abutment 220 slides within the sliding hole 121, and the elastic element 210 is housed within the sliding hole 121. The sliding engagement between the abutment 220 and the sliding hole 121 effectively guides the movement of the abutment 220, improving its smoothness and preventing it from jamming during contact with the first clamp 11a, thus ensuring the elastic element 200 effectively absorbs impact energy. Since the elastic element 210 is housed within the sliding hole 121, the hole effectively protects the elastic element 210, preventing it from failing to deform elastically due to external interference, and also ensuring the elastic element 200 effectively absorbs impact energy. On the other hand, the elastic element 210 can make full use of the existing space of the sliding hole 121, avoiding the elastic element 210 occupying the installation space outside the sliding hole 121, thereby improving the structural compactness of the clamping mechanism 12c.

[0049] See Figure 7 , Figure 8 and Figure 9 In some embodiments, the abutment member 220 includes a first abutment section 221 and abutment section 222, which can be coaxially arranged. The first abutment section 221 is located below the second abutment section 222, allowing a portion of the first abutment section 221 to be outside the sliding hole 121, thus causing the first abutment section 221 to protrude relative to the connecting unit 100 so that it contacts the first clamp 11a. The second abutment section 222 protrudes from the end face of the first abutment section 221, which is the upper end face of the first abutment section 221, allowing the second abutment section 222 to be located within the sliding hole 121. The middle portion of this end face is covered by the second abutment section 222, while the edge portion of the end face, not covered by the second abutment section 222, forms a stepped surface 223. This stepped surface 223 surrounds the second abutment section 222, making the entire abutment member 220 resemble a stepped shaft structure. The elastic element 210 is sleeved on the second abutting section 222 and abuts against the step surface 223; thus, the second abutting section 222 can position the elastic element 210 radially along the second abutting section 222, and the step surface 223 can position the elastic element 210 axially along the second abutting section 222.

[0050] See Figure 7 , Figure 8 and Figure 9In some embodiments, the sliding hole 121 includes a first hole 1211 and a second hole 1212 coaxially arranged. The diameter of the first hole 1211 is larger than the diameter of the second hole 1212. The first hole 1211 is located below the second hole 1212. The first hole 1211 is slidably engaged with the first abutting section 221, and the second hole 1212 is slidably engaged with the second abutting section 222. The elastic member 210 can be located inside the first hole 1211, and the first abutting section 221 cannot enter the second hole 1212. The elastic member 210 abuts between the stepped surface 223 and the bottom wall surface of the first hole 1211, so that the bottom wall surface of the first hole 1211 can play a good limiting role for the elastic member 210 and the first abutting section 221.

[0051] See Figure 7 , Figure 8 and Figure 9 In some embodiments, the connecting unit 100 includes a first connecting member 110 and a second connecting member 120. The first connecting member 110 is connected to the driving mechanism 12b and can be a plate-like structure. The second connecting member 120 protrudes from the surface of the first connecting member 110 facing the support member 12a. For example, the first connecting member 110 and the second connecting member 120 can be connected perpendicularly. The second connecting member 120 is more flexible than the first connecting member 110. A sliding hole 121 is provided on the second connecting unit 100, allowing the elastic unit 200 to be disposed on the second connecting member 120. For example, the second connecting member 120 can be made of flexible silicone material, thus giving it higher flexibility. Given that the more flexible second connecting member 120 protrudes from the first connecting member 110, it can effectively prevent the less flexible first connecting member 110 from contacting the first clamp 11a, thus avoiding a rigid collision between the first connecting member 110 and the first clamp 11a. When the abutment 220 is completely contained within the sliding hole 121 and the second connector 120 contacts the first clamp 11a, it can be ensured that the highly flexible second connector 120 forms a flexible collision with the first clamp 11a, thus avoiding damage to the connecting unit 100 and the first clamp 11a.

[0052] In some embodiments, the clamping mechanism 12c further includes a first sensor disposed on the connecting unit 100 and / or the elastic unit 200. The first sensor is used to send feedback information to control the movement of the clamping mechanism 12c. For example, the first sensor can be a pressure sensor disposed on the abutment member 220. When the pressure of the pressure sensor reaches a set value, the clamping mechanism 12c can stop moving to stop increasing the pressure on the first clamp 11a, thus preventing the workpiece to be plated from becoming over-tensioned. Alternatively, the second sensor can be a distance sensor disposed on the connecting unit 100. When the distance sensor detects that the distance between the first connecting member 110 and the first clamp 11a is less than a set value, the clamping mechanism 12c can also stop moving to stop increasing the pressure on the first clamp 11a, thus preventing the workpiece to be plated from becoming over-tensioned.

[0053] In some embodiments, the drive mechanism 12b includes a drive cylinder, the cylinder barrel of which is fixed to the support member 12a, and the piston rod of the drive cylinder is connected to the clamping mechanism 12c. The up-and-down extension and retraction of the piston rod of the drive cylinder can drive the clamping mechanism 12c to move vertically closer to or further away from the first clamp 11a. In other embodiments, the drive mechanism 12b may include a hydraulic cylinder, a linkage mechanism, a belt mechanism, and a cam mechanism, etc.

[0054] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the clamping device 12 further includes a transfer mechanism 12d, which includes a transferor that drives the carrier 12a to move closer to or away from the first clamp 11a, so that the clamping mechanism 12c can contact the first clamp 11a. Specifically, when it is necessary to apply downward pressure to the first clamp 11a, the transferor can drive the carrier 12a to move closer to the first clamp 11a, thereby causing the clamping mechanism 12c and the drive mechanism 12b to move synchronously with the carrier 12a. When the clamping mechanism 12c is directly above the first clamp 11a, the transferor can stop driving the carrier 12a to move closer to the first clamp 11a. When the workpiece to be plated is electroplated on the clamping mechanism 11, in order to avoid the clamping device 12 interfering with the workpiece to be plated, the transferor can drive the carrier 12a to move away from the first clamp 11a.

[0055] In some embodiments, both the clamping mechanism 12c and the carrier 12a move linearly in directions perpendicular to each other. For example, the clamping mechanism 12c moves linearly in the vertical direction, while the carrier 12a moves linearly in the horizontal direction. In other embodiments, the carrier 12a can rotate in the horizontal direction, allowing it to move closer to or away from the first clamp 11a.

[0056] In some embodiments, the transfer device may include a transfer cylinder, the cylinder barrel of which is fixedly mounted, and the piston rod of the transfer cylinder is connected to the carrier 12a. When the piston rod of the transfer cylinder extends or retracts in the horizontal direction, it can drive the carrier 12a to move closer to or further away from the first clamp 11a. In other embodiments, the transfer device may also include a hydraulic cylinder, a linkage mechanism, a belt mechanism, and a cam mechanism, etc.

[0057] In some embodiments, the transfer mechanism 12d further includes a second sensor disposed on the carrier 12a and used to send feedback information to control the movement of the carrier 12a. For example, the second sensor can be a distance sensor, etc., so that the second sensor is used to detect the distance between the carrier 12a and the first clamp 11a. For example, when the clamping mechanism 12c is just above the first clamp 11a, the second sensor sends feedback information, thereby causing the transferor to stop driving the carrier 12a to continue moving based on the feedback information.

[0058] This application also provides an electroplating production line, which includes the aforementioned hanger 10. By setting the hanger 10, the electroplating quality of the workpiece to be plated can be effectively improved.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
