Description

Technical Field

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

[0002] In the electronics manufacturing industry, the storage of printed circuit boards (PCBs) is a key factor affecting production efficiency. Currently, the mainstream PCB storage racks are mainly divided into three categories: traditional double-tray racks, drawer-type racks, and intelligent storage racks, among which traditional double-tray racks are the most widely used.

[0003] Traditional double-tray shelving units feature a symmetrical design with 3-8 metal trays on each side. While this design offers ample storage space, it presents challenges for display and retrieval. Viewing circuit boards or accessing boards on the other side requires multiple 180° rotations of the shelving unit, which is time-consuming and labor-intensive. Furthermore, frequent rotations can easily cause circuit boards to collide. Additionally, the double-tray configuration occupies a significant aisle width, typically around 1.2 meters, restricting passage and hindering movement.

[0004] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a circuit board placement rack that solves the problems of display, retrieval obstacles, and inconvenience in turnover of existing circuit board placement racks.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example: A circuit board placement rack, such as Figure 1-7 As shown, the assembly includes a base frame 1, rollers 2, a first placement component 3, a second placement component 4, a first locking mechanism, and a second locking mechanism. The base frame 1 is a rectangular frame, and four rollers 2 are installed at the four corners of the bottom of the base frame 1. The first placement component 3 is fixed to the base frame 1. Both the first placement component 3 and the second placement component 4 are used to place circuit boards, and the second placement component 4 is rotatably connected to the first placement component 3.

[0038] Preferably, the first placement component 3 includes a first support frame 31 and a first storage tray 32. The first support frame 31 consists of two uprights, and a crossbar can be appropriately added between the two uprights to improve connection stability. The bottom of the first support frame 31 is fixed to the base frame 1, and the first storage tray 32 is fixed to one side of the first support frame 31.

[0039] Specifically, multiple first storage trays 32 are provided along the height direction of the first support frame 31, and the multiple first storage trays 32 are arranged at equal intervals.

[0040] In the above technical solution, multiple first storage trays 32 arranged at equal intervals realize the layered utilization of vertical space, which greatly improves the storage capacity compared with a single-layer storage structure. The four-roller base 1 design enables 360° free movement, and together with the rotating second placement component 4, the operating radius is reduced.

[0041] Preferably, the second placement component 4 includes a second support frame 41, a second storage tray 42, pulleys 43, and a hydraulic rod 44. The second support frame 41 consists of two uprights and at least one crossbar, and is rotatably connected to the first support frame 31. The second storage tray 42 is fixed on the second support frame 41.

[0042] Specifically, multiple second storage trays 42 are provided along the height direction of the second support frame 41, and the multiple second storage trays 42 are arranged at equal intervals.

[0043] Specifically, a rotating shaft 7 is fixed on one of the columns of the first support frame 31. The length direction of the rotating shaft 7 is consistent with the length direction of the column, that is, both are vertically arranged. The rotating shaft 7 passes through one of the columns of the second support frame 41, that is, the second support frame 41 can rotate around the rotating shaft 7 by 0-180°.

[0044] In the above technical solution, the vertical rotating shaft 7 structure ensures that the center of gravity of the circuit board placement rack remains within the support surface during rotation, avoiding the risk of tipping over. The equally spaced multi-layered storage trays improve vertical space utilization, and the rotating shaft 7 enables rotational retrieval and placement, reducing the width of the passageway. The vertical rotating shaft 7, combined with the rotatable frame, allows operators to complete double-sided retrieval and placement without repeatedly rotating the placement rack, saving time and effort.

[0045] Preferably, the pulley 43 is installed at the bottom of the hydraulic rod 44, and the upper end of the hydraulic rod 44 is fixed to the bottom of the second support frame 41.

[0046] More preferably, the pulley 43 is installed on the other side of the second support frame 41 relative to the rotatable connection between the second support frame 41 and the first support frame 31.

[0047] In the above technical solution, the hydraulic rod 44 and the pulley 43 combine to form a support structure, so that the unfolded placement frame has a relatively stable connection strength, which facilitates the pushing of the unfolded placement frame and improves the stability and installation strength of the placement frame. When the placement frame needs to be merged, that is, when the second support frame 41 needs to be rotated to the back of the first support frame 31, the hydraulic rod 44 can drive the pulley 43 to move upward, at which time the pulley 43 leaves the ground, making it simple and convenient to use.

[0048] Reference Figure 1-7 The first locking mechanism includes a first limiting block 51, a first positioning shaft 52, and a first insert plate 53. The first limiting block 51 is fixed to the other side of the first support frame 31 relative to the rotatable connection between the first support frame 31 and the second support frame 41. The first positioning shaft 52 is fixed to the other side of the second support frame 41 relative to the rotatable connection between the second support frame 41 and the first support frame 31. One end of the first insert plate 53 is sleeved on the first positioning shaft 52. The top of the first limiting block 51 has a first insertion slot adapted to the first insert plate 53, and the first insert plate 53 is used to be inserted into the first insertion slot.

[0049] In the above technical solution, after the placement racks are combined, the first placement component 3 and the second placement component 4 need to be locked to prevent the first placement component 3 from rotating freely around the rotating shaft 7, thereby affecting the stability of the circuit board placement. To this end, the present invention provides a first locking mechanism. When using the first locking mechanism, it is only necessary to rotate the first insert plate 53 so that the first insert plate 53 is inserted into the socket.

[0050] Preferably, the second locking mechanism includes a second limiting block 51, a second positioning shaft 62, and a second insert plate 63. The first limiting block 51 is fixed on the first support frame 31 and near the rotatable connection between the first support frame 31 and the second support frame 41. The second positioning shaft 62 is fixed on the second support frame 41 and near the rotatable connection between the first support frame 31 and the second support frame 41. One end of the second insert plate 63 is sleeved on the second positioning shaft 62. The second limiting block 61 has a second insertion slot adapted to the second insert plate 63, and the second insert plate 63 is used to be inserted into the second insertion slot.

[0051] In the above technical solution, after the placement rack is unfolded, the first placement component 3 and the second placement component 4 need to be locked to prevent the first placement component 3 from rotating freely around the rotating shaft 7, thereby affecting the stability of the circuit board placement. To this end, the present invention provides a second locking mechanism. When using the second locking mechanism, it is only necessary to rotate the second insert plate 63 so that the second insert plate 63 is inserted into the second socket.

[0052] In summary, this circuit board placement rack can be unfolded or merged as needed. When merged, the first placement component 3 and the second placement component 4 are located on the front and rear sides of the rack, respectively, which maximizes space utilization and makes the structure more stable. When unfolded, the first placement component 3 and the second placement component 4 are both arranged side by side on the front side of the rack, making display and retrieval more convenient and allowing for smooth passage through narrow passages during turnover, making it very flexible to use.
