Description

Technical Field

[0001] The utility model relates to the technical field of improved design of tooling for plate electroplating, in particular to a hoisting fixture for PCB electroplating. Background Art

[0002] The electroplating process of a circuit board refers to immersing the circuit board in an electroplating solution so that a metal layer is formed on the surface of the circuit board or in the conductive hole through electroplating. The current electroplating process requires the use of a lifting fixture to fix the PCB board and immerse it in the electroplating agent for electroplating. However, the current lifting fixture structure is too simple, and the operation is cumbersome when installing and removing the PCB board, which takes a lot of time. In addition, the stability is poor during the lifting process, which may cause the PCB board to shake or even fall, resulting in poor electroplating effect. When the PCB board is fixed, it is fixed in contact with the side of the circuit board, which affects the overall electroplating effect. It is impossible to make targeted adjustments to circuit boards of different sizes, and the practicality of the device is poor.

[0003] In the prior art, a patent with announcement number CN217579119U discloses a circuit board electroplating fixture, in which both sides of the circuit board have symmetrical finished product areas, and the peripheries of the finished product areas are all process frames. The electroplating fixture includes: a middle frame and two side frames, and the side frames are respectively arranged on both sides of the middle frame, and a circuit board can be clamped between the middle frame and the side frames on both sides. The middle frame and the side frames are both annular frame structures. When the circuit board is clamped between the middle frame and the side frames, the inner cavity contour of the annular frame coincides with the edge of the finished product area, and the outer contour of the annular frame is within the range of the process frame. The outer walls of the middle frame and the side frames are provided with a polytetrafluoroethylene coating. It is suitable for clamping circuit boards with larger process edges to reduce metal waste and save production costs.

[0004] The patent with announcement number CN215946499U discloses a PCB circuit board electroplating lifting fixture, including a lifting fixture main body, the lifting fixture main body includes: a receiving body, the receiving body includes a mounting assembly and an upper clamping member fixedly connected to the middle position of the bottom end of the mounting assembly; a sliding clamp group, the sliding clamp group is slidably connected to the mounting assembly; and a fixed clamp group, the fixed clamp group is detachably connected to the mounting assembly, and by setting a stabilizing member, the threaded cylinder can be used to drive the pressure plate to move upward to tighten the connection part with the external fixed structure, so that the lifting fixture main body can be more stably connected to the external device, avoiding the shaking of the device during the lifting and moving process, causing the PCB board to fall, and further improving the electroplating effect of the PCB board.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] Reference Figure 1-6 As shown, a lifting fixture for PCB electroplating of the utility model comprises a frame 2 for accommodating the PCB board 3 to be electroplated. Specifically, the left side plate 22 and the right side plate of the frame 2 are arranged relatively to each other and are both provided with a plurality of support blocks 20. The support blocks 20 are arranged horizontally. The PCB board 3 is placed on two support blocks 20 at the same height. The PCB can be pushed into the frame 2 for placement or push out in combination with a horizontal conveying mechanism such as a push rod, thereby improving the overall loading and unloading work efficiency; a locking mechanism 1, wherein the locking mechanism 1 comprises a screw rod 12 and a pressing block 13. The screw rod 12 is provided with a handle 11. The pressing block 13 is processed with a threaded hole 133 that matches the screw rod 12. One end of the pressing block 13 is slidably arranged on a guide plate 10. The guide plate 10 is fixed on the left side plate 22 or the right side plate. The other end of the pressing block 13 is arranged at the notch of the left side plate 22 or the right side plate. The screw rod 12 rotates to make the pressing block 13 rise and fall to compress or loosen the PCB board 3 placed on the support block 20. The PCB board 3 is placed horizontally and the clamping operation can be realized synchronously.

[0032] Embodiment 2

[0033] Reference Figure 1-6 As shown, based on the technical solution of the first embodiment, a PCB electroplating lifting fixture, for the specific structural design of the frame 2, as shown in FIG. Figure 4 As shown, the left side plate 22 or the right side plate is processed with a notch to accommodate the lifting and lowering activities of the pressure block 13, and the notch divides the horizontal support block 20 into two parts. Similarly, the left side plate 22 or the right side plate is also divided into two parts. In order to increase the structural strength of the left side plate 22 and the right side plate and the support block 20, the left side plate 22 and the right side plate are designed as a whole plate structure, and the support block 20 is generally horizontally welded to the left side plate 22 and the right side plate.

[0034] Furthermore, the frame 2 also includes a bottom plate 23, which has two limit blocks 231 extending outward. The two limit blocks 231 are symmetrically arranged and the guide plate 10 is clamped therebetween. The limit blocks 231 are designed to limit the bottom activity range of the guide plate 10, usually to limit its left and right shaking, and can also limit the front and back directions, that is, the limit blocks 231 extend in the front and back directions to clamp the guide plate 10, so that the four sides of the limit blocks 231 are restricted and the bottom shaking will not affect the guiding function.

[0035] Furthermore, the frame 2 further comprises a top plate 21, and the top plate 21 and the bottom plate 23 are both fixedly connected to the left side plate 22 and the right side, and one side of the frame 2 is opened to facilitate the horizontal placement or removal of the PCB board 3, that is, the front of the frame 2 is used for the feeding and unloading operation of the PCB board 3. In addition, a rib plate is provided between the top plate 21 and the bottom plate 23, such as Figure 1 As shown, a vertical rib plate is provided at the back of the frame 2 to increase the structural strength. The back is not designed as a complex reinforcing rib structure or an integral plate in order to facilitate the outward push of the PCB board 3, that is, the PCB is pushed forward by a push rod and falls onto the belt conveyor mechanism to enter the next process. At this time, the entire fixture is lifted and its own height is adjusted so that each layer of PCB boards 3 can be pushed out one by one.

[0036] Furthermore, the top plate 21 is also processed with a lifting hole 221 that matches the lifting ring to facilitate subsequent lifting operations. The top plate 21 and the bottom plate 23 are also designed with a reinforcing rib structure according to actual needs, which can be designed horizontally or vertically or a combination of the two.

[0037] Embodiment 3

[0038] Reference Figure 1-6 As shown, based on the technical solution of the second embodiment, a PCB electroplating lifting fixture, for the specific structural design of the locking mechanism 1, as shown in FIG. Figure 5-6As shown, the guide plate 10 described above is an L-shaped plate, the horizontal plate of the guide plate 10 is fixed to the left plate 22 or the right plate, and the vertical plate of the guide plate 10 is clamped in the extension component at the bottom of the frame 2, that is, the bottom of the vertical plate is located between the two limit blocks 231. In addition, a vertical T-shaped slot is processed on the guide plate 10, and a T-shaped block 131 matching the T-shaped slot is processed on the pressing block 13, so that the guide plate 10 has a vertical guiding function.

[0039] Furthermore, a buffer pad 134 is provided at the lower part of one end of the pressing block 13. The buffer pad 134 is designed to prevent the PCB board 3 from being damaged by excessive force when the pressing block 13 descends. The material of the buffer pad 134 is selected according to the electroplating solution and has a certain deformation ability. The height of the pressing block 13 is the same as the height of the support block 20 to prevent the top or bottom size of the pressing block 13 from affecting the entry and exit of the PCB board 3 along the support block 20.

[0040] Furthermore, as described above, a vertical first open groove 121 is processed on the screw 12, and a vertical second open groove 132 is processed in the threaded hole 133. The two open grooves are designed to facilitate the rapid discharge of the electroplating solution to avoid excessive residue in the thread gap, which affects the rotation operation of the screw 12. The height difference between the two adjacent support blocks 20 on the frame 2 is the same as the height difference between the two adjacent pressure blocks 13 on the locking mechanism 1, so that the pressure blocks 13 have a uniform lifting height and synchronously tighten or loosen the PCB board 3 on the support blocks 20. At the same time, in order to facilitate actual operation, the size of each support block 20 is the same, the spacing between the two adjacent support blocks 20 is the same, the size of each pressure block 13 is the same, and the spacing between the two adjacent pressure blocks 13 is the same. In this way, when each pressure block 13 is assembled with the screw 12, it is only necessary to pad it with an equal height block, and the height of the equal height block is the spacing between the two adjacent support blocks 20.

[0041] In the device of the utility model, the assembly and matching relationship of each component, the material and size parameters of each component are selected according to actual needs. For example, the position of the lifting ring, the number and pitch of the screw 12, the size of the limit block 231, etc. are existing technologies or materials. The relevant technical personnel can directly purchase or customize them from the market according to the required product models and specifications.

[0042] The above is only a preferred specific embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned embodiment, and the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme of the utility model and its utility model concept, shall be covered within the protection scope of the utility model.
