Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a circuit board copper plating basket. Background Technology

[0002] In circuit board manufacturing, copper plating is applied to the substrate, followed by etching to lay out the circuitry. During copper plating, the circuit boards are often secured using clamps. However, this method limits the number of circuit boards that can be plating at once, thus impacting manufacturing efficiency. Other methods include... Figure 3 The suspended platform shown is used for copper plating of circuit boards. This type of platform can complete copper plating of multiple circuit boards at once, and is therefore widely used in the industry. The platform includes a rectangular base frame 1, with multiple lower support rods 11 inside the rectangular base frame 1. The two ends of the rectangular base frame 1 have end recesses 10, which are fixed together by multiple long horizontal rods 13. Limiting inner plates 14 are welded to the long horizontal rods 13, and multiple limiting V-grooves 15 are formed on the limiting inner plates 14. Multiple inner horizontal rods 12 are provided inside the end recesses 10. During copper plating, the circuit board is placed vertically inside the platform. During placement, the limiting V-grooves 15 limit the circuit board, while the lower support rods 11 support the circuit board. However, this type of platform can only perform copper plating of circuit boards of a single size, and the limiting V-grooves 15 can easily scratch the circuit board during placement. Utility Model Content

[0003] This utility model provides a circuit board copper plating basket to overcome the shortcomings of the prior art, and solves the problems of the narrow application range and easy scratching of the circuit board by the existing baskets, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A circuit board copper plating basket includes a lower frame with a rectangular structure. Concave parts are welded to both ends of the lower frame, and multiple pairs of sleeves are welded and fixed to each concave part. A reinforcing crossbar is provided between the sleeves at the same end. Connecting support rods are welded to the outer periphery of the sleeves, and constraint tubes are welded to the outer ends of the connecting support rods. Side concave rods pass through the constraint tubes on the same side, with both ends of the side concave rods extending into the constraint tubes. Limiting side plates are welded to the horizontal sections of the side concave rods, and limiting grooves are formed on the inner sides of the limiting side plates. The limiting grooves limit the circuit board, and the side concave rods are retractable onto the constraint tubes. During operation, the circuit board can be placed first, and then the limiting side plates can be pushed inward to position the circuit board. This method avoids damage to the circuit board and facilitates limiting operations on circuit boards of different sizes, thus expanding its applicability.

[0006] Furthermore, multiple strips are welded parallel to the length direction of the lower frame. The length direction of the strips is parallel to the length direction of the lower frame. The strips can support the lower end of the placed circuit board to prevent the circuit board from falling when the size of the circuit board is small.

[0007] Furthermore, the strip has multiple lower slots along its length, and the lower slots correspond one-to-one with the limiting slots. The lower slots can limit the circuit board and ensure an effective gap between the circuit boards during copper plating, thus facilitating the copper plating operation.

[0008] Furthermore, both the lower slot and the limiting slot are V-shaped. This V-shape reduces the contact area between the circuit board and the lower slot and limiting slot, thus avoiding any impact on the copper plating effect. Specifically, after the circuit board is placed, the inclined surfaces of the lower slot and limiting slot act on the edges of the circuit board, thereby achieving the purpose of positioning the circuit board. This structure also facilitates the positioning of circuit boards of different thicknesses.

[0009] Furthermore, in order to lock the concave rod and improve the positioning effect of the circuit board, a pair of limiting nuts are threaded to both ends of the concave rod. T-shaped seats are fitted at both ends of the concave rod, with the T-shaped seats located between each pair of limiting nuts. The T-shaped seats are fitted onto the reinforcing crossbar. An inner top screw is rotatably provided at the outer end of the T-shaped seat. An inner top concave part is threaded to the inner top screw. An end cap is provided at the outer end of the inner top screw. A pair of protruding plates are welded to both sides of the inner end of the inner top concave part. A pressure rod is provided on each pair of protruding plates. A pressure block is fitted on the pressure rod. An oblique hole is opened on the pressure block. The inner end of the oblique hole extends upward at an angle. The pressure rod passes through the oblique hole. An L-shaped pressure plate is provided at the inner end of the pressure block. The vertical section of the L-shaped pressure plate passes through the inner end of the T-shaped seat, and the inner end of the L-shaped pressure plate acts on the reinforcing crossbar.

[0010] The advantages of the above technical solution are:

[0011] This invention expands the applicability of the hanging basket and avoids damage to the circuit board during placement. Attached Figure Description

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0013] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0014] Figure 2 A magnified view of point A is shown.

[0015] Figure 3 A three-dimensional structural diagram of the existing suspended basket is shown. Detailed Implementation

[0016] like Figures 1-3 As shown, a circuit board copper plating basket includes a lower frame 2, which has a rectangular structure. Concave parts 3 are welded to both ends of the lower frame 2. Multiple strips 20 are welded inside the lower frame 2 parallel to its length direction. The length direction of the strips 20 is parallel to the length direction of the lower frame 2. Multiple lower slots 21 are formed on the strips 20 along their length direction.

[0017] Multiple pairs of sleeves 4 are welded and fixed on the concave part 3. A reinforcing crossbar 40 is provided between the sleeves 4 at the same end. A connecting support rod 42 is welded on the outer periphery of the sleeve 4. A constraint tube 43 is welded to the outer end of the connecting support rod 42. A side concave rod 44 is inserted into the constraint tube 43 on the same side. Both ends of the side concave rod 44 are inserted into the constraint tube 43. A limiting side plate 54 is welded on the horizontal section of the side concave rod 44. A limiting groove 55 is formed with an opening on the inner side of the limiting side plate 54. The lower locking groove 21 and the limiting groove 55 are in a one-to-one correspondence. Both the lower locking groove 21 and the limiting groove 55 have a V-shaped structure.

[0018] Both ends of the concave rod 44 are threadedly connected to a pair of limiting nuts 45. T-shaped seats 41 are fitted onto both ends of the concave rod 44, with each T-shaped seat 41 positioned between the pairs of limiting nuts 45. The T-shaped seats 41 are fitted onto the reinforcing crossbar 40. An inner top screw 46 is rotatably mounted on the outer end of the T-shaped seat 41. An inner top recess 48 is threadedly connected to the inner top screw 46. An end cap 47 is provided on the outer end of the inner top screw 46, and the inner end of the inner top recess 48... A pair of protruding plates 49 are welded on each side. Each pair of protruding plates 49 is provided with a pressure rod 50. A pressure block 51 is fitted on the pressure rod 50. An oblique hole 52 is opened on the pressure block 51. The inner end of the oblique hole 52 extends upward. The pressure rod 50 passes through the oblique hole 52. An L-shaped pressure plate 53 is provided on the inner end of the pressure block 51. The vertical section of the L-shaped pressure plate 53 passes through the inner end of the T-shaped seat 41, and the inner end of the L-shaped pressure plate 53 acts on the reinforcing crossbar 40.

[0019] When in use, the operator places the circuit board vertically on the lower slot 21 of the strip 20 and positions the circuit board using the lower slot 21. Multiple circuit boards can be placed on the strip 20 in this way. After the circuit board is placed, the inclined surface of the lower slot 21 acts on the edge of the circuit board, thereby achieving the purpose of positioning the circuit board.

[0020] Then push the concave rod 44 to move the limiting side plate 54 to both sides of the circuit board, and make the inclined surface of the limiting groove 55 act on the edges of both sides of the circuit board.

[0021] The operator then rotates the inner top screw 46 via the end cap 47, causing the inner top screw 46 to move the inner top recess 48 inward. As the inner top recess 48 moves inward, the pressure rod 50 on it acts on the oblique hole 52, ultimately causing the inner end of the vertical section of the L-shaped pressure plate 53 to act on the reinforcing crossbar 40. At this point, the positioning of the opposite concave rod 44 is completed. The basket is then hung on the mounting bracket, and the copper plating operation is performed.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
