Description

Technical Field

[0001] This application relates to the field of electroplating, and more particularly to a telescopic electroplating bracket. Background Technology

[0002] Generally, electroplating racks are of fixed size and can only be used for electroplating operations on sheets of specific dimensions. This means that when dealing with sheets of different sizes, multiple electroplating racks of different specifications need to be prepared, which not only increases production costs but also occupies a lot of storage space. Moreover, frequently changing electroplating racks of different specifications will reduce production efficiency and increase operational complexity and time costs. Summary of the Invention

[0003] To address the problems in the background art, the present invention aims to provide a telescopic electroplating support, comprising a first telescopic portion, a second telescopic portion, and a telescopic section. The first telescopic portion includes a first sleeve, a first crossbar connecting the first sleeve, and a plurality of first clamps disposed on the first crossbar, the first clamps being used to clamp one end of a workpiece. The second telescopic portion includes a second sleeve, a second crossbar connecting the second sleeve, and a plurality of second clamps disposed on the second crossbar, the second clamps being used to clamp the other end of the workpiece. The telescopic section connects the first sleeve and the second sleeve, and the telescopic section is used to drive the second sleeve to extend into or retract from the first sleeve, thereby changing the distance between the first clamps and the second clamps.

[0004] In some possible implementations, the telescopic part includes a driving member and a transmission member, the driving member being connected to the transmission member, the driving member being fixedly disposed inside the first sleeve, and the transmission member being tractively connected to the second sleeve.

[0005] In some possible implementations, the transmission component includes a screw and a gear, and the inner wall of the second sleeve is provided with a rack, one side of the gear meshing with the screw and the other side of the gear meshing with the rack.

[0006] In some possible implementations, there are two gears, two racks, and the screw is inserted centrally into the second sleeve, with the screw positioned between the two gears.

[0007] In some possible implementations, the second telescopic portion further includes a sealing element disposed at the end of the second sleeve, the sealing element having a through hole through which the screw can be movably passed.

[0008] In some possible implementations, the end of the second sleeve is provided with a protrusion, and the first sleeve is provided with a plurality of positioning holes spaced apart along the axial direction, wherein the protrusion can be inserted into any one of the positioning holes.

[0009] In some possible implementations, there are two first sleeves, which are respectively connected to both ends of the first crossbar to form a semi-enclosed structure; and there are two second sleeves, which are respectively connected to both ends of the second crossbar to form a semi-enclosed structure.

[0010] In some possible implementations, a plurality of the first clamps are spaced apart from the first crossbar, and a plurality of the second clamps are spaced apart from the second crossbar.

[0011] In some possible implementations, the outer surface of the second sleeve is provided with a plurality of graduations spaced apart along the axial direction, the plurality of graduations being used to indicate the length by which the second sleeve extends into or out of the first sleeve.

[0012] In some possible implementations, the telescopic electroplating bracket further includes a control unit and a sensor. The control unit is electrically connected to the sensor and the telescopic part. The sensor is used to acquire the length information of the plate. The control unit generates a control electrical signal based on the length information. The telescopic part drives the second sleeve to extend into or out of the first sleeve based on the control electrical signal.

[0013] The electroplating bracket provided in this application connects a telescopic part between a first sleeve and a second sleeve. This telescopic part can drive the second sleeve into or out of the first sleeve, thereby increasing or decreasing the distance between the first clamp connecting the first sleeve and the second clamp connecting the second sleeve. The first clamp and the second clamp hold both ends of the packaging substrate to be electroplated, thus enabling adaptation to the size of the packaging substrate and improving the versatility and flexibility of the electroplating bracket. When dealing with packaging substrates of different sizes, there is no need to frequently change different models of electroplating brackets, saving production and time costs.

[0042] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings of specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0044] Please see Figure 1 , Figure 2 as well as Figure 3 This application provides a telescopic electroplating support 100 (hereinafter referred to as the electroplating support 100) in one embodiment. The electroplating support 100 can be used in the electroplating process of various workpieces, providing stable support and positioning for various workpieces, and ensuring the uniformity and quality of electroplating. Various workpieces include packaging substrates, electronic components, hardware accessories, etc. This application uses a packaging substrate as an example for illustrative description.

[0045] The electroplating support 100 includes a first telescopic portion 10, a second telescopic portion 20, and a telescopic section 30. The first telescopic portion 10 includes a first sleeve 11, a first crossbar 13, and a plurality of first clamps 12. The first crossbar 13 is connected to the first sleeve 11. The plurality of first clamps 12 are disposed on the first crossbar 13 and are used to clamp one end of the encapsulation substrate. The second telescopic portion 20 includes a second sleeve 21, a second crossbar 24, and a plurality of second clamps 22. The second crossbar 24 is connected to the second sleeve 21. The plurality of second clamps 22 are disposed on the second crossbar 24 and are used to clamp the other end of the encapsulation substrate. The telescopic section 30 connects the first sleeve 11 and the second sleeve 21. The telescopic section 30 is used to drive the second sleeve 21 to extend into or retract from the first sleeve 11, thereby changing the distance between the first clamps 12 and the second clamps 22. Understandably, in other embodiments of this application, the telescopic portion 30 can be used to drive the first sleeve 11 to extend into or retract from the second sleeve 21.

[0046] The electroplating bracket 100 provided in this application connects a telescopic part 30 between a first sleeve 11 and a second sleeve 21. The telescopic part 30 can drive the second sleeve 21 into or out of the first sleeve 11, thereby increasing or decreasing the distance between the first clamp 12 connecting the first sleeve 11 and the second clamp 22 connecting the second sleeve 21. The first clamp 12 and the second clamp 22 hold both ends of the packaging substrate to be electroplated, thus enabling adaptation to the size of the packaging substrate and improving the versatility and flexibility of the electroplating bracket 100. When dealing with packaging substrates of different sizes, it is not necessary to frequently change different models of the electroplating bracket 100, saving production and time costs.

[0047] Please see Figure 2 , Figure 3 as well as Figure 4In this embodiment, the telescopic part 30 includes a driving member 31 and a transmission member 32, with the driving member 31 connected to the transmission member 32. The driving member 31 is fixedly disposed inside the first sleeve 11, and the transmission member 32 is tractively connected to the second sleeve 21. Part of the transmission member 32 is located inside the first sleeve 11, and the other part extends outside the first sleeve 11. The driving member 31 drives the transmission member 32, and the transmission member 32 drives the second sleeve 21, causing the second sleeve 21 to extend into or retract from the first sleeve 11. The driving member 31 is a servo motor, which has precise control performance and can meet the accuracy requirements of the telescopic operation. The transmission member 32 includes a screw 321 and a gear 322, and a rack 211 is provided on the inner wall of the second sleeve 21. One side of the gear 322 meshes with the screw 321, and the other side of the gear 322 meshes with the rack 211. Specifically, when the servo motor rotates in the forward direction, it drives the screw 321 to rotate in the forward direction. The forward rotation of the screw 321 drives the gear 322, which meshes with it, to rotate in a specific direction. Since the other side of the gear 322 meshes with the rack 211 on the inner wall of the second sleeve 21, the rotation of the gear 322 causes the second sleeve 21 to extend into the first sleeve 11. When the servo motor rotates in the reverse direction, the screw 321 rotates in the reverse direction, thereby driving the gear 322 to rotate in the reverse direction, so that the second sleeve 21 exits the first sleeve 11.

[0048] In this embodiment, there are two gears 322 and two racks 211. The double-gear and double-rack design, compared to a single gear-rack structure, provides a more balanced force distribution and a more stable transmission effect. The screw 321 is centrally inserted into the second sleeve 21, and the screw 321 is located between the two gears 322. Each gear 322 meshes with one rack 211 on one side and with the screw 321 on the other side. This layout helps to make the entire transmission structure more symmetrical in space, and from a mechanical point of view, it can effectively reduce the possible skewing or jamming caused by uneven force distribution.

[0049] During operation, when the screw 321 rotates, it simultaneously drives the two gears 322 to rotate synchronously. Each gear 322 meshes with its corresponding rack 211, thus converting the rotational motion of the screw 321 into a smoother and more precise linear motion of the second sleeve 21. This structural design further improves the accuracy and stability of the second sleeve 21's insertion into or withdrawal from the first sleeve 11, thereby allowing for more precise adjustment of the distance between the first clamp 12 and the second clamp 22, better adapting to electroplating operations on packaging substrates of different sizes.

[0050] In this embodiment, the second telescopic portion 20 further includes a sealing member 23, which is disposed at the end of the second sleeve 21. On one hand, the sealing member 23 prevents external impurities from entering the interior of the second sleeve 21. In the electroplating working environment, various electroplating solution droplets, dust particles, and other impurities may exist. If these impurities enter the interior of the second sleeve 21, they will interfere with the normal operation of the telescopic portion 30, for example, affecting the meshing of the gear 322 and rack 211, and the rotation of the screw 321, thereby reducing the performance and service life of the electroplating bracket. On the other hand, the sealing member 23 is provided with a through hole 231 through which the screw 321 can movably pass. The through hole 231 provides a stable moving channel for the screw 321, ensuring that the screw 321 maintains an accurate movement trajectory during the process of driving the gear 322 to rotate and thus extending and retracting the second sleeve 21, and will not deviate due to a lack of limiting. Meanwhile, the movable connection between the sealing member 23 and the screw 321 can also support the screw 321 to a certain extent, share the force on the screw 321 during operation, and help improve the stability and reliability of the telescopic part 30 structure.

[0051] Please see Figure 4 In this embodiment, the end of the second sleeve 21 is provided with a protrusion 212, and the first sleeve 11 is provided with a plurality of positioning holes 111 spaced apart along the axial direction. The protrusion 212 can be inserted into any one of the positioning holes 111. The cooperation between the protrusion 212 and the positioning hole 111 can achieve precise axial positioning. When it is necessary to fix the second sleeve 21 in a specific position, the protrusion 212 is inserted into the corresponding positioning hole 111 to ensure the accuracy of the position of the second sleeve 21 relative to the first sleeve 11, and to ensure the stability of the distance between the first clamp 12 and the second clamp 22, thereby stably clamping packaging substrates of different sizes for electroplating operations.

[0052] Furthermore, the inner wall of the first sleeve 11 is provided with a groove (not shown) along the axial direction, and a plurality of positioning holes 111 are spaced apart in the groove. The protrusion 212 can move within the groove, thereby restricting the rotation of the second sleeve 21 within the first sleeve 11. The groove is configured to provide a track for the protrusion 212 to move. When the protrusion 212 moves within the groove, it can only move along the axial direction, thus effectively restricting the rotation of the second sleeve 21 within the first sleeve 11. This helps to maintain the structural stability and functionality of the entire electroplating bracket. Understandably, if the second sleeve 21 rotates within the first sleeve 11, it may disrupt the meshing relationship between the gear 322 and the rack 211, thereby affecting the normal operation of the telescopic part 30, making it impossible to accurately adjust the distance between the first clamp 12 and the second clamp 22, and ultimately affecting the electroplating effect of the encapsulation substrate.

[0053] In this embodiment, the electroplating support 100 is generally rectangular. There are two first sleeves 11, each connected to both ends of the first crossbar 13 to form a semi-enclosed structure. Multiple first clamps 12 are spaced apart on the first crossbar 13. This semi-enclosed structure design allows the first telescopic portion 10 to effectively fix part of the packaging substrate edge from one side. Furthermore, because the two first sleeves 11 are connected to the first crossbar 13, the stability and rigidity of the structure are guaranteed to a certain extent, preventing deformation or shaking caused by external forces during the electroplating process, thus avoiding impact on the electroplating effect. There are also two second sleeves 21, each connected to both ends of the second crossbar 24 to form a semi-enclosed structure. Multiple second clamps 22 are spaced apart on the second crossbar 24. Similarly, this semi-enclosed structure of the second telescopic portion 20 cooperates with the first telescopic portion 10. When the first telescopic portion 10 and the second telescopic portion 20 adjust their relative positions via the telescopic part 30 to fit the size of the encapsulation substrate, the two semi-enclosed structures can completely surround the edge of the encapsulation substrate, providing a stable clamping effect from both sides. Furthermore, the connection between the second crossbar 24 and the two second sleeves 21 enhances the overall structural strength of the second telescopic portion 20, ensuring that the electroplating support 100 can stably support the encapsulation substrate during the electroplating process, thus ensuring the uniformity and quality of the electroplating.

[0054] In this embodiment, the outer surface of the second sleeve 21 is provided with multiple graduations (not shown) spaced apart along the axial direction. These graduations indicate the length by which the second sleeve 21 extends into or out of the first sleeve 11. The operator can intuitively determine the positional relationship of the second sleeve 21 relative to the first sleeve 11 using these graduations. In practical applications, when it is necessary to adjust the distance between the first clamp 12 and the second clamp 22 according to the size of the packaging substrate, the operator can quickly and accurately adjust the second sleeve 21 to the appropriate position. For example, if the clamp spacing required for a specific size packaging substrate is known, the operator can directly refer to the graduations to push or pull the second sleeve 21 into or out to the corresponding marked position without performing complex measurement or adjustment processes, thus improving work efficiency.

[0055] Please see Figure 5 In this embodiment, the electroplating bracket 100 further includes a control unit 40 and a sensor 50. The control unit 40 is electrically connected to the sensor 50 and the telescopic part 30. The sensor 50 is used to acquire the length information of the plate material. The control unit 40 generates a control electrical signal based on the length information. The telescopic part 30 drives the second sleeve 21 to extend into or retract from the first sleeve 11 based on the control electrical signal. The control unit 40 includes one of a programmable logic controller (PLC), a microcontroller (such as a 51 microcontroller or an STM32 microcontroller), or a digital signal processor (DSP). The sensor 50 includes one of a photoelectric sensor, an ultrasonic sensor, or a linear variable differential transformer (LVDT) sensor.

[0056] In practice, when sensor 50 detects that the length of the encapsulation substrate is too long, it transmits this length information to control unit 40. Control unit 40 calculates and determines that the distance between the first clamp 12 and the second clamp 22 needs to be increased to accommodate the length of the encapsulation substrate. Therefore, control unit 40 generates a corresponding control signal, which instructs the drive member 31 of the telescopic section 30 to perform an action in a specific direction and amplitude. Upon receiving the control signal, the drive member 31 of the telescopic section 30 begins to operate, driving the second sleeve 21 out of the first sleeve 11 via a transmission member 32 (such as the engagement of a screw 321 and a gear 322) until the distance between the first clamp 12 and the second clamp 22 matches the length of the encapsulation substrate.

[0057] When sensor 50 detects that the packaged substrate is too short, it transmits the length information to control unit 40. Control unit 40 calculates that the distance between the first clamp 12 and the second clamp 22 needs to be reduced, and then generates a corresponding control signal. Based on this control signal, telescopic part 30 drives the second sleeve 21 to extend into the first sleeve 11, adjusting the distance between the first clamp 12 and the second clamp 22 to a suitable length for the shorter packaged substrate. This ensures that the electroplating bracket 100 can accurately adapt to packaged substrates of different lengths, guaranteeing the smooth progress of the electroplating process.
