Description

Technical Field

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

[0002] Currently, the industry standard for circuit board storage is shelf-style direct storage, where finished circuit boards that have completed testing are placed horizontally on ordinary shelves. While this storage method is simple and straightforward, it has significant drawbacks in practical applications: when there are more than two circuit boards vertically, they usually need to be stacked, which poses a risk of damaging lower-layer circuit boards due to stacking pressure. Furthermore, when it is necessary to retrieve the bottom circuit boards, the upper-layer circuit boards must be removed one by one, resulting in low operational efficiency. In addition, under the existing storage method, when different models of circuit boards are mixed together, it is necessary to rely on cushioning materials such as pearl cotton for physical isolation, which increases material costs and also affects the warehouse staff's ability to quickly identify the boards because the markings are obscured.

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] The first aspect of this utility model is to provide a storage rack, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a limiting frame 2, and a support frame 3; The frame 1 has multiple horizontally arranged receiving cavities, which are configured to accommodate vertically arranged plates 4. The ends of the receiving cavities along the vertical direction are provided with limiting structures for inserting plates 4. Both the limiting frame 2 and the support frame 3 are connected to the bottom of the frame 1. The limiting frame 2 has a first limiting groove 21 configured to cooperate with the shelf 5 and define the position of the frame 1 relative to the shelf 5 along the insertion direction of the receiving cavity. The support frame 3 is configured to support the surface of the shelf 5.

[0024] When the storage rack provided in the above embodiments is used, such as Figure 2 As shown, the limiting frame 2 can cooperate with the shelf 5 and limit the position of the frame 1 relative to the shelf 5 along the insertion direction of the receiving cavity. At the same time, the support frame 3 supports the surface of the shelf 5, and the plate 4 can be vertically inserted into each receiving cavity through the limiting structure.

[0025] Therefore, the above-mentioned storage rack can avoid the safety and quality hazards caused by the existing stacked storage method. The boards 4 are stored vertically and independently. When taking out any board 4, there is no need to move the other boards 4. The boards 4 do not interfere with each other, improving operational efficiency. Moreover, the storage rack can stably cooperate with the shelf 5 to ensure the stability of the board 4 storage.

[0026] There are multiple ways in which the limit frame 2 and the shelf 5 can be matched. For example, the limit frame 2 and the shelf 5 can be snapped together, or the limit frame 2 and the shelf 5 can be connected by bolts, pins and other connecting parts. Therefore, there are also multiple options for the structure of the limit frame 2.

[0027] In alternative implementations, such as Figure 1 As shown, the limiting frame 2 includes a first longitudinal beam 22 and a first vertical beam 23. The first longitudinal beam 22 is connected to the bottom of the frame 1 and extends along the insertion direction. Both ends of the first longitudinal beam 22 are vertically connected to the first vertical beam 23, and a first limiting groove 21 is formed between the first vertical beam 23 at both ends.

[0028] When in use, the support plate 52 on the shelf 5 can be snapped into the first limiting groove 21. At this time, the first longitudinal beam 22 overlaps on the support plate 52, and the two first vertical beams 23 can abut against the side wall of the shelf 5 along the insertion direction, thereby limiting the position of the frame 1 relative to the support plate 52 in the above direction.

[0029] The aforementioned limit frame 2 has a simple design, is easy to process, and can effectively improve the connection reliability between the storage rack and the shelf 5.

[0030] Wherein, both the first longitudinal beam 22 and the first vertical beam 23 may adopt a plate-like structure. Compared with a tubular structure, it not only facilitates the connection between the frame 1 and the limiting frame 2, but also can reduce the weight of the limiting frame 2 as much as possible.

[0031] In an optional embodiment, as shown in Figure 1 , the limiting frame 2 further comprises a bottom plate 24, the bottom plate 24 is connected to any one of the first vertical beams 23, and the bottom plate 24 is arranged at an angle to the first vertical beam 23 along the extending direction of the first vertical beam 23 to form a hook-like structure. Specifically, the bottom plate 24 is arranged opposite to and parallel with the first longitudinal beam 22 along the extending direction of the first vertical beam 23.

[0032] In use, the bottom plate 24 can extend to the bottom surface of the bearing plate 52, so as to cooperate with the first longitudinal beam 22 to limit the position of the frame 1 relative to the bearing plate 52 in the direction perpendicular to the bearing plate 52, making the position of the storage rack relative to the shelf 5 more stable.

[0033] Preferably, the first longitudinal beam 22, the first vertical beam 23 and the bottom plate 24 adopt an integrated structure.

[0034] Any structure capable of providing a supporting function can be the support frame 3 mentioned in the above embodiments. For example, the support frame 3 adopts a laterally placed U-shaped structure, one end of which is connected to the bottom of the frame 1 and the other end of which is supported on the bearing plate 52, or the support frame 3 adopts an L-shaped structure, one end of which is welded to the bottom of the frame 1 and the other end of which is supported on the bearing plate 52, and so on.

[0035] In an optional embodiment, as shown in Figure 3 , the support frame 3 comprises a first cross beam 31 and two bent beams 32. The first cross beam 31 extends in a direction perpendicular to the insertion direction and is fixedly connected to the bottom of the frame 1 for transmitting supporting force. Two ends of the first cross beam 31 are respectively connected with the bent beams 32, and the bent beams 32 are bent downward and finally supported on the upper surface of the shelf 5, thereby forming a stable supporting structure and further enhancing the load-bearing capacity and installation stability of the frame 1.

[0036] Wherein, the bottom end of the bent beam 32 facing away from the first cross beam 31 is arranged in a bent manner, specifically, it can be bent inward so as to be disposed directly opposite to the first cross beam 31; or as shown in Figure 3 , bent outward so as to be staggered from the first cross beam 31 in the vertical direction. At this time, the support frame 3 is in a "several" shape, and the outwardly bent portion of the bent beam 32 can be connected to the bearing plate 52 through a connecting member such as a screw.

[0037] Preferably, the first cross beam 31 and the bent beam 32 adopt an integrated structure.

[0038] In each of the above embodiments, the limiting frame 2 and the support frame 3 can be configured as one or more. When multiple are configured, the configuration direction can be perpendicular to the insertion direction. The limiting frame 2 and the support frame 3 can be alternately distributed in the configuration direction. The support frame 3 can be distributed on the outside and the limiting frame 2 can be concentrated on the inside, or the limiting frame 2 can be distributed on the outside and the support frame 3 can be concentrated on the inside.

[0039] by Figure 1 Taking this example, there are two limit frames 2 and two support frames 3. The two limit frames 2 are connected to the two ends of the bottom of the frame 1 in a direction perpendicular to the insertion direction. The two support frames 3 are located inside the two limit frames 2 and are arranged opposite to each other in the insertion direction.

[0040] Frame 1 can be a fixed frame structure or an assembled and adjustable frame structure, thus enabling the use of boards 4 of different sizes.

[0041] In an optional embodiment, the frame 1 includes multiple horizontally arranged first support beams 113 extending along the insertion direction to support the plate 4 and define its installation position within the receiving cavity. Each first support beam 113 has a retaining edge on both sides along its length, which extends upward from the top edge of the first support beam 113 to form a limiting structure on both sides of the plate 4, thereby preventing the plate 4 from undergoing large lateral displacement or tilting during storage and ensuring its stable upright position within the receiving cavity.

[0042] Furthermore, to facilitate the accurate insertion of the bottom end of the board 4 between the two side flanges and thus smoothly enter the receiving cavity, at least one end of the first support beam 113 is provided with a first insertion channel 1121. The first insertion channel 1121 includes a straight extension section, the cross-sectional width of which remains unchanged and is smaller than the distance between the two side flanges, so as to guide the board 4 to be inserted between the two side flanges and reduce the collision between the board 4 and the flanges.

[0043] In a specific embodiment, the first insertion channel 1121 may be disposed at both ends of the first support beam 113.

[0044] In alternative implementations, such as Figure 5 As shown, the first insertion channel 1121 has a port at its end along the insertion direction. The port is the entrance for the board 4 to enter the first insertion channel 1121. In order to improve the centering and guiding performance of the insertion process, the first insertion channel 1121 includes a first guide section 1122 located near the port. The end of the first guide section 1122 away from the port is connected to a straight extension section. The opening of the first guide section 1122 gradually increases along the direction that gradually approaches the port.

[0045] During the insertion process, the board 4 first contacts the large opening end of the first guide section 1122, and automatically adjusts its posture under the action of the first guide section 1122, gradually aligning with the middle part of the first insertion channel 1121, thereby achieving smooth insertion. The setting of the first guide section 1122 not only improves the insertion efficiency of the board 4, but also reduces the assembly difficulty of the board 4.

[0046] Specifically, the longitudinal cross-sectional shape of the first guide section 1122 can be a trumpet-shaped or tapered expansion structure, so that the board 4 can be guided to the correct alignment position during the insertion process, thereby reducing insertion failure or structural damage caused by skewness or misalignment.

[0047] The aforementioned longitudinal section is parallel to the top surface of the first support beam 113.

[0048] The gradual increase in the opening of the first guide section 1122 can be achieved by setting the inner wall surface of the first guide section 1122 as an inclined surface, which is inclined at a certain angle relative to the insertion direction, so that the opening on the side closer to the port is larger than the opening on the side farther from the port. This inclination angle can be reasonably set according to the actual dimensional error of the insert, material properties, and assembly requirements.

[0049] In an optional implementation, the limiting structure includes a second limiting groove, such as... Figure 4 As shown, the frame 1 also includes a fixing frame 11, which includes a lower support 111 and a limiting plate assembly 112, wherein: The lower bracket 111 has a circular hole 132. A limiting bracket 2 and a support bracket 3 are connected to the lower side of the lower bracket 111. A limiting plate assembly 112 is connected to the upper side of the lower bracket 111 and has multiple recessed receiving grooves 1111. Both ends of the first support beam 113 are embedded in the receiving grooves 1111 to achieve a stable connection between the first support beam 113 and the lower bracket 111. This structure not only improves the installation accuracy of the first support beam 113 but also enhances the stability and vibration resistance of the overall structure.

[0050] The limiting plate assembly 112 has a first insertion channel 1121 located above each of the first support beams 113, and a second limiting groove is formed between the first insertion channel 1121 and the first support beam 113. Specifically, the first insertion channel 1121 can limit the plate 4 in a direction perpendicular to the insertion direction, and the first support beam 113 can support the plate in a vertical direction, so that the bottom end of the plate 4 can be fully limited and supported after entering the receiving cavity.

[0051] Specifically, such as Figure 5As shown, in order to avoid the first support beam 113 obstructing the installation of the limiting plate assembly 112, the top surface of the end of the first support beam 113 embedded in the receiving groove 1111 is flush with the top surface of the two lower supports 111, or the top surface of the aforementioned end is lower than the top surface of the two lower supports 111, thereby facilitating the extension of the limiting plate assembly 112 above the first support beam 113.

[0052] In alternative implementations, such as Figure 5 As shown, the limiting plate assembly 112 includes an end plate 1123 located at the end and at least one guide plate 1124 located between the end plates 1123. The arrangement direction of the end plates 1123 and each guide plate 1124 is perpendicular to the insertion direction.

[0053] A first insertion channel 1121 is formed between the end plate 1123 and the adjacent guide plate 1124. A first insertion channel 1121 is formed between two adjacent guide plates 1124. The end plate 1123 and the guide plate 1124 can be connected to the lower bracket 111 by screws or other connectors.

[0054] In alternative implementations, such as Figure 6 As shown, the end face of the lower bracket 111 along the insertion direction is configured to abut against the limiting part 41 on the board to limit the insertion depth of the board 4.

[0055] Specifically, when the board 4 is inserted into the second limiting groove along the insertion direction, the limiting part 41 on the board 4 moves synchronously with the board. When the board 4 is inserted into place, the limiting part 41 contacts the aforementioned end face of the lower bracket 111 and forms a rigid abutment, thereby preventing the board 4 from being inserted further, ensuring that it is accurately installed in the predetermined position of the receiving cavity, and preventing the board 4 from sliding out from the other end of the receiving cavity.

[0056] In alternative implementations, such as Figure 4 As shown, the lower support 111 includes a bottom beam 1112 and a second vertical beam 1113; the bottom beam 1112 is bent into an inverted U-shape, and a receiving groove 1111 is recessed on the top surface of the bottom beam 1112; the second vertical beam 1113 extends vertically, and the bottom end of the second vertical beam 1113 has a bent section, which is connected to the bottom beam 1112, and the first longitudinal beam 22 is connected to the bottom surface of the bent section.

[0057] The connection methods mentioned in the above embodiments may include, but are not limited to, welding, screw connection, etc.

[0058] In an optional embodiment, the limiting structure includes a third limiting groove 1211, and the frame 1 also includes a movable frame 12 and an adjusting component 13. The movable frame 12 is arranged opposite to the fixed frame 11 in the vertical direction and forms multiple receiving cavities with the fixed frame 11. The movable frame 12 is connected to the fixed frame 11 through the adjusting component 13. The adjusting component 13 is configured to adjust the distance between the movable frame 12 and the fixed frame 11 in the vertical direction, thereby realizing the adjustment of the size of the receiving cavity.

[0059] During use, the user can adjust the relative position between the movable frame 12 and the fixed frame 11 by adjusting the component 13, thereby changing the height of the accommodating space to accommodate different sizes and models of boards 4.

[0060] The structure of the adjustment component 13 can be, but is not limited to, a nut and screw structure, a slide rail adjustment structure, or a telescopic connection component such as a pneumatic cylinder or a hydraulic cylinder. Its specific form can be selected according to actual needs, as long as it can achieve flexible adjustment of the distance between the movable frame 12 and the fixed frame 11.

[0061] like Figure 1 As shown, the adjustment component 13 includes a waist-shaped hole 131, a round hole 132, a bolt, and a nut. One of the waist-shaped hole 131 and the round hole 132 is disposed on the movable frame 12, and the other is disposed on the fixed frame 11. Multiple waist-shaped holes 131 and round holes 132 can be configured, and they are all distributed in the vertical direction. The bolt can pass through the waist-shaped hole 131 and the round hole 132 and be locked by the nut. By adjusting the locking state of the nut, the friction between the movable frame 12 and the fixed frame 11 can be adjusted, thereby adjusting the distance between the movable frame 12 and the fixed frame 11 in the vertical direction.

[0062] Specifically, the top of the second vertical beam 1113 is provided with a round hole 132 and a scale for displaying the movement size of the movable frame 12. The movable frame 12 is provided with a waist-shaped hole 131.

[0063] In alternative implementations, such as Figure 7 As shown, the limiting structure includes a third limiting groove 1211, and the movable frame 12 includes an upper support 121. The upper support 121 is connected to the fixed frame 11 through the adjusting component 13, and the upper support 121 is recessed with the third limiting groove 1211.

[0064] The aforementioned third limiting groove 1211 can limit the top of the board 4, and together with the second limiting groove, it can support the board 4 from the top and bottom respectively, thereby ensuring that the board 4 is stably placed in the receiving cavity.

[0065] Similar to the second limiting groove, the third limiting groove 1211 has a second insertion channel and a second guide section disposed near the port of the second insertion channel, the opening of the second guide section gradually increasing in the direction of gradually approaching the port.

[0066] In alternative implementations, such as Figure 4 As shown, the upper support 121 includes a top beam 1212 and a second support beam 1213. The top beam 1212 is bent into an inverted U-shape, and a third limiting groove 1211 is recessed on the bottom surface of the top beam 1212. The top beam 1212 has waist-shaped holes 131 at both ends. The second support beam 1213 extends along the insertion direction, and the end of the second support beam 1213 overlaps the top beam 1212 and is connected to the top beam 1212 by screws or other connecting parts.

[0067] In an optional implementation, to make the structure of frame 1 more robust, such as... Figure 4 As shown, the frame 1 also includes a third vertical beam 14 and a fourth vertical beam 15 that extend vertically. The top end of the third vertical beam 14 is connected to the top beam 1212, and the bottom end of the fourth vertical beam 15 is connected to the guide plate 1124. An adjustment component 13 can be connected between the top end of the fourth vertical beam 15 and the bottom end of the third vertical beam 14.

[0068] The second aspect of this utility model provides a board storage device. The board storage device provided by the second aspect of this utility model includes a shelf 5 and the aforementioned storage rack. The shelf 5 includes at least one storage layer 51 arranged in the vertical direction. Each storage layer 51 is provided with at least one storage rack. The limiting frame 2 in the storage rack is engaged with the shelf 5 through a first limiting groove 21, and the support frame 3 is supported on the surface of the shelf 5.

[0069] Reference Figure 2 The shelf 5 may include three storage layers 51, and each storage layer 51 may have multiple storage racks placed side by side, which can realize the vertical storage of the board 4.

[0070] The card storage device provided by the second aspect of this utility model has the following advantages: 1. It can avoid the safety and quality hazards caused by the existing method of stacking and storing circuit boards on shelves, and the number of circuit boards stored per unit area can be effectively increased; 2.
