[0001] The utility model relates to the technical field of printed circuit board manufacturing, and particularly relates to a hanging basket mechanism. Background Art
[0002] Copper deposition is the abbreviation of electroless copper plating and is also a step in the process of manufacturing printed circuit boards. After the printed circuit board is drilled, it is immersed in a copper deposition solution. Copper ions in the copper deposition solution gain electrons and are reduced to metallic copper, which is deposited on the hole wall, enabling the originally insulated holes to conduct electricity. In the copper deposition process, the printed circuit board needs to be installed on a hanging basket and then immersed in a copper deposition tank. Existing hanging baskets can basically only carry printed circuit boards of fixed sizes, and the equipment has low versatility. Printed circuit boards of different batches may have different sizes due to different types and processing technologies. To perform copper deposition on printed circuit boards of different batches, different hanging baskets have to be used, which is very troublesome, time-consuming, and laborious.

[0021] The realization, functional features and advantages of the purpose of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners
[0022] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] Referring to Figures 1 to 3 , the present utility model provides a hanging basket mechanism, including a cross beam 1 and a basket body 2. Mounting parts 11 are arranged at both ends of the cross beam 1; the basket body 2 is connected to the cross beam 1. The basket body 2 is composed of multiple interconnected frame rods 3 and forms a feeding surface 31. A plurality of insertion holes 32 are formed through two opposite frame rods 3 at the bottom of the basket body 2. A plurality of first limiting strips 4 are movably connected to the insertion holes 32. Insertion columns 41 are arranged at both ends of the first limiting strip 4. The insertion columns 41 can be inserted into / removed from any insertion hole 32 to adjust the distance between the first limiting strips 4. A plurality of slots 42 are equidistantly arranged on the first limiting strip 4 to insert and fix the circuit board.
[0024] It can be understood that the mounting parts 11 at both ends of the cross beam 1 are used to hang the entire hanging basket on a moving mechanism or a copper deposition tank for copper deposition. The basket body 2 is composed of multiple frame rods 3, forming a space for installing the circuit board inside. And one side of the basket body 2 is a feeding surface 31. The circuit board is put into the basket body 2 from the feeding surface 31 for installation. A row of insertion holes 32 are arranged on two opposite frame rods 3 at the bottom of the basket body 2 for placing the first limiting strips 4. Insertion columns 41 are arranged at both ends of the first limiting strip 4. When the insertion columns 41 are inserted into the insertion holes 32, the first limiting strip 4 is fixed at the bottom of the basket body 2. A plurality of slots 42 are formed on the first limiting strip 4. The circuit board is erected and the edge is inserted into the slots 42 for fixation. By inserting the circuit board into the slots 42 at different positions, the distance between the circuit boards can also be adjusted.
[0025] When installing a circuit board with a larger size for electroless copper plating, the first limiting strip 4 can have a larger spacing and a smaller number, which helps to reduce the weight of the entire hanging basket and increase its service life. When installing a circuit board with a smaller size, the spacing of the first limiting strip 4 can be adjusted smaller and the number can be increased to make the first limiting strip 4 more densely arranged. To adjust the spacing of the first limiting strip 4, just pick up the first limiting strip 4 upward so that the insertion posts 41 at both ends of the first limiting strip 4 leave the insertion holes 32, then align the insertion posts 41 with the insertion holes 32 at the desired position, and then put it down to complete the position adjustment. This method is simple and convenient, time-saving and labor-saving, and has a simple structure, which is convenient for production.
[0026] Referring to Figure 2 , in an embodiment of the present application, both ends of the first limiting strip 4 extend outward and are gradually bent to form a placement portion 43, and the frame rod 3 is attached to the placement portion 43.
[0027] It can be understood that the placement portion 43 forms a hook-shaped structure at both ends of the first limiting strip 4. The two hooks fit on the surface of the frame rod 3 and hook the frame rod 3, which can provide a part of the limiting function, so that the first limiting strip 4 cannot move back and forth on the frame rod 3, increasing the stability of the circuit board installed on the first limiting strip 4, and at the same time, it will not affect the taking and placing of the first limiting strip 4 from the frame rod 3.
[0028] Referring to Figure 2 , in an embodiment of the present application, at least one insertion post 41 protrudes from the placement portion 43 corresponding to the insertion hole 32.
[0029] It can be understood that the insertion post 41 is located inside the hook-shaped placement portion 43. The placement portion 43 can provide a certain protection for the insertion post 41 so that it is not directly exposed and damaged by collision. The insertion post 41 should be set as long as possible. The longer insertion post 41 can make the first limiting strip 4 more stable after being inserted into the insertion hole 32, not easy to loosen, and not easy to shake, which will affect the electroless copper plating of the circuit board. Further, two insertion posts 41 can be arranged side by side and can be inserted into two insertion holes 32 at the same time, so that the first limiting strip 4 can be more stable and not easy to loosen.
[0030] Referring to Figure 1 , in an embodiment of the present application, a cross bar 5 is provided on the side of the basket body 2 opposite to the feeding surface to limit the circuit board inside the basket body 2.
[0031] It can be understood that the cross bar 5 can block the circuit board to prevent it from tilting. Moreover, the cross bar 5 can make the structure of the entire basket body 2 more stable, improve its bearing capacity, and enhance the anti-deformation ability of the basket body 2, making its service life longer.
[0032] Referring toFigure 1 In an embodiment of the present application, a movable rod 51 is movably connected between the cross bar 5 and the frame rod 3 above it. Second limit bars 6 are movably connected to the side of the basket body 2 adjacent to the feeding surface, on the cross bar 5, and on the movable rod 51. Fixing grooves 61 are equidistantly arranged on the second limit bars 6, and the opening directions of the fixing grooves 61 all face the circuit board, so as to insert the edge of the circuit board into the fixing grooves 61 for limit fixing.
[0033] It can be understood that the movable rod 51 can slide left and right along the cross bar and the frame rod 3. Second limit bars 6 are movably connected to the side of the basket body 2 adjacent to the feeding surface, on the cross bar 5, and on the movable rod 51. The second limit bars 6 at these three positions respectively correspond to the other three sides of the circuit board after it is inserted into the slot 42. Fixing grooves 61 are formed on the second limit bars 6, and the fixing grooves 61 all face the circuit board. By adjusting the positions of the second limit bars 6, the edges of the three sides of the circuit board are inserted into the fixing grooves 61, which can play a good role in fixing the circuit board and prevent it from shaking during the copper deposition process and affecting the copper deposition effect; there are two second limit bars 6 on the cross bar 5, and the opening directions of the fixing grooves 61 on them are opposite to each other. When installing circuit boards with smaller sizes, one row of circuit boards may be installed on the left and right sides in the basket body 2, and the two limit bars on the cross bar 5 can respectively limit and fix the circuit boards between the two rows of circuit boards.
[0034] Refer to Figure 3 In an embodiment of the present application, movable sleeves 62 are provided at one end or both ends of the movable rod 51 and the second limit bars 6. The movable sleeves 62 are sleeved on the cross bar 5 or the frame rod 3 or the movable rod 51 and can slide or rotate, so as to adjust the position and angle of the second limit bars 6 so that the fixing grooves 61 are inserted into the edges of the circuit board.
[0035] It can be understood that the movable sleeve 62 is a sleeve, sleeved on the cross bar 5 or the frame rod 3 or the movable rod 51, and can slide or rotate along them. Through the above settings, the position and angle of the second limit bars 6 can be adjusted according to the different sizes of the circuit boards, so that the fixing grooves 61 on the second limit bars 6 can be perfectly inserted into the edges of the circuit board to achieve the best fixing effect on the circuit board.
[0036] Refer to Figure 3 In an embodiment of the present application, the movable sleeve 62 is provided with a fastening screw 63, and the fastening screw 63 is rotated to fix the movable sleeve 62 on the cross bar 5 or the frame rod 3.
[0037] Understandably, after adjusting the position and angle of the second limiting strip 6 so that it is plugged into the circuit board, turning the fastening screw 63 can make the movable sleeve 62 tightly attached to the cross bar 5 or the frame rod 3 or the movable rod 51, and it can no longer be rotated or slid. Through the above settings, it is possible to prevent the second limiting strip 6 fixing the circuit board from shaking, avoiding affecting the copper deposition process of the circuit board.
[0038] Referring to Figure 3 , in an embodiment of the present application, an operating handle 64 is provided at the free end of the fastening screw 63.
[0039] Understandably, the operating handle 64 can facilitate the user to turn the fastening screw 63, enabling the user to increase the force-bearing area during turning and making the turning process more labor-saving.
[0040] In the technical solution of the present utility model, a first limiting strip 4 that can be freely disassembled and adjusted in position is provided on the basket body 2. The first limiting strip 4 has a slot 42 for installing a circuit board. By adjusting the number and spacing of the first limiting strips 4, different sizes of circuit boards can be correspondingly carried. And a second limiting strip 6 is also provided on the side of the basket body 2. A fixing groove 61 is opened on the second limiting strip 6. Moving the second limiting strip 6 can make the edge of the circuit board inserted into the fixing groove 61 for limiting and fixing. This technical solution can carry different sizes of circuit boards without replacing the hanging basket, with simple operation, time-saving and labor-saving.
