Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board storage rack technology, and in particular to a combinable storage rack for circuit boards. Background Technology
[0002] Currently, the industry mainly uses strip racks and L-shaped racks for storing circuit boards. Strip racks have a simple structure, with slots on the end face, making them suitable for the rapid storage and turnover of smaller circuit boards, which can improve turnover efficiency in the mass production stage of small boards. However, when it comes to the production stage of larger circuit boards, strip racks cannot provide horizontal and vertical bidirectional restraint. Due to the high center of gravity of the circuit boards, they are prone to tipping over and component collisions. Therefore, L-shaped racks are needed to stably fix larger circuit boards with a right-angle structure.
[0003] To meet the storage needs of different production stages, companies need to purchase both strip racks and L-shaped racks: during the production cycle of small boards, L-shaped racks are idle for a long time, occupying storage space; when large boards are produced, strip racks become idle assets, resulting in a great waste of equipment resources. Utility Model Content
[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a combined storage rack that can flexibly switch storage forms according to production needs.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A modular storage rack for circuit boards includes a first strip-shaped board frame and a second strip-shaped board frame. A plurality of first storage slots for placing circuit boards are spaced apart on the left and right sides of the end face of the first strip-shaped board frame, and a plurality of second storage slots for placing circuit boards are spaced apart on the left and right sides of the end face of the second strip-shaped board frame. A detachable connection structure is provided between the first and second strip-shaped board frames, connecting them into a mutually perpendicular L-shape. The plurality of first storage slots and the plurality of second storage slots are arranged in a one-to-one correspondence.
[0007] In some embodiments, the detachable connection structure includes insert plates disposed on the left and right sides of the rear end of the first strip plate frame, and sockets for insert plates to be inserted are provided on the left and right sides of the end face of the second strip plate frame. When the insert plate is inserted into the socket, the first strip plate frame and the second strip plate frame are connected and combined to form an L-shape that is perpendicular to each other.
[0008] In some embodiments, sliding grooves are provided on both the left and right sides of the rear end of the first strip plate frame, and the two insert plates slide back and forth in the sliding grooves. Limiting grooves communicating with the sliding grooves are provided on both the left and right sides of the first strip plate frame, and limiting blocks are provided on the insert plates, with the limiting blocks movably disposed in the limiting grooves.
[0009] In some embodiments, a locking member is also included, which can keep the insert plate locked in a position where it is slid into the groove, or in a position where it is inserted into the socket.
[0010] In some embodiments, the locking element is a pin. A first insertion hole communicating with a slide groove is provided on the side wall of the first strip plate frame, and a second insertion hole communicating with a socket is provided on the side wall of the second strip plate frame. A locking hole is provided on the insertion plate. When the insertion plate is locked in the form of sliding into the slide groove, the pin passes through the first insertion hole and is inserted into the locking hole. When the insertion plate is locked in the form of being inserted into the socket, the pin passes through the second insertion hole and is inserted into the locking hole.
[0011] In some embodiments, the outer wall of the pin is provided with an external thread, and the inner wall of the locking hole is provided with an internal thread that connects with the external thread.
[0012] In some embodiments, handle notches are provided on both the left and right sides of the first and second strip-shaped plate frames.
[0013] In some embodiments, both the first strip plate frame and the second strip plate frame are made of antistatic material.
[0014] The structure can be flexibly adjusted according to the production stage. During the batch production and turnover stage of small circuit boards, two independent strip-shaped racks (the first and second strip-shaped racks) can be used separately. A single-direction storage slot enables dense storage and rapid retrieval of small boards, meeting the requirements for efficient turnover. When entering the production and storage stage of large circuit boards, the first and second strip-shaped racks can be combined into an L-shape through a detachable connection structure, forming horizontal and vertical right-angle limits to effectively fix large circuit boards, preventing tipping damage and meeting stable storage requirements. No rack replacement is required; simple disassembly and assembly completes the form change, reducing production preparation time by more than 60%, significantly improving production efficiency, and perfectly adapting to multi-specification, multi-stage production scenarios.

[0019] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0020] like Figures 1-4 A modular storage rack for circuit boards is shown, characterized in that it includes a first strip-shaped board frame 1 and a second strip-shaped board frame 2. A plurality of first storage slots 3 for placing circuit boards are spaced apart on the left and right sides of the end face of the first strip-shaped board frame 1. A plurality of second storage slots 4 for placing circuit boards are spaced apart on the left and right sides of the end face of the second strip-shaped board frame 2. A detachable connection structure is provided between the first strip-shaped board frame 1 and the second strip-shaped board frame 2, connecting and combining the first strip-shaped board frame 1 and the second strip-shaped board frame 2 into a mutually perpendicular L-shape. The plurality of first storage slots 3 and the plurality of second storage slots 4 are arranged in a one-to-one correspondence.
[0021] When small circuit boards need to be stored, the first strip board holder 1 and the second strip board holder 2 are placed independently, and the small circuit boards are directly inserted into the corresponding first storage slot 3 or second storage slot 4, and the storage is achieved by using the slot body to limit the movement.
[0022] When large circuit boards need to be stored, the first strip board frame 1 and the second strip board frame 2 are fixed in an L-shape by a detachable connection structure. At this time, the storage slot of the first strip board frame 1 is horizontal and the storage slot of the second strip board frame 2 is vertical. The bottom of the large circuit board is inserted into the first storage slot 3 in the horizontal direction and the side is inserted into the second storage slot 4 in the vertical direction. Stable fixation is achieved by horizontal and vertical bidirectional limiting.
[0023] Furthermore, there is no need to replace the board frame; the form can be changed simply by disassembly and assembly, reducing production preparation time by more than 60%, significantly improving production efficiency, and perfectly adapting to multi-specification and multi-stage production scenarios.
[0024] See Figures 2-4As shown, the detachable connection structure includes insert plates 21 located on the left and right sides of the rear end of the first strip plate frame 1, and insertion slots 22 for inserting the insert plates 21 are provided on the left and right sides of the end face of the second strip plate frame 2. When the insert plate 21 is inserted into the insertion slot 22, the first strip plate frame 1 and the second strip plate frame 2 are connected and combined to form an L-shape that is perpendicular to each other.
[0025] When switching to an L-shape, align the insert plate 21 at the rear end of the first strip plate frame 1 with the slot 22 of the second strip plate frame 2 and insert it vertically until the insert plate 21 is fully inserted into the slot 22 (the rear end of the insert plate is flush with the edge of the slot). At this time, the two strip plate frames automatically form a 90° vertical L-shape.
[0026] Furthermore, sliding grooves 31 are provided on both the left and right sides of the rear end of the first strip plate frame 1, and the two insert plates 21 slide back and forth in the sliding grooves 31. Limiting grooves 32 communicating with the sliding grooves 31 are provided on both the left and right sides of the first strip plate frame 1. Limiting blocks 33 are provided on the insert plates 21, and the limiting blocks 33 are movably disposed in the limiting grooves 32.
[0027] When assembly is required, manually push the limiting block 33 to slide forward along the limiting groove 32, causing the insert plate 21 to extend out of the slide groove 31 until the block slides to the front end of the limiting groove 32 (end of the stroke). At this time, the extension length of the insert plate 21 meets the requirements of the insertion port 22. When the insert plate needs to be stored, push the block to slide backward along the limiting groove, and the insert plate 21 is retracted into the slide groove 31 until the block slides to the rear end of the limiting groove, so as to avoid the insert plate occupying space or being damaged by collision when idle.
[0028] Furthermore, it also includes a locking element that can keep the insert plate 21 locked in the form of sliding into the groove 31, or keep the insert plate 21 locked in the form of being inserted into the socket 22.
[0029] The locking element is a pin 51. A first insertion hole 52 communicating with the slide groove 31 is provided on the side wall of the first strip plate frame 1, and a second insertion hole 53 communicating with the insertion port 22 is provided on the side wall of the second strip plate frame 2. A locking hole 54 is provided on the insertion plate 21. When the insertion plate 21 is locked in the form of sliding into the slide groove 31, the pin 51 passes through the first insertion hole 52 and is inserted into the locking hole 54. When the insertion plate 21 is locked in the form of being inserted into the insertion port 22, the pin 51 passes through the second insertion hole 53 and is inserted into the locking hole 54.
[0030] Retraction and locking process: Push the limit block 33 to retract the insert plate 21 into the slide groove 31. At this time, the locking hole 54 of the insert plate is aligned with the first insertion hole 52 of the first strip plate frame. After passing the pin 51 through the first insertion hole 52, insert it into the locking hole 54. The insert plate is fixed and cannot slide forward.
[0031] Extension locking process: Push the lever to extend the insert plate 21 and insert it into the socket 22 of the second strip plate frame. At this time, the locking hole 54 of the insert plate is aligned with the second socket 53 of the second strip plate frame. After the pin 51 passes through the second socket 53, it is inserted into the locking hole 54. The insert plate is fixed and cannot slide backward, thereby locking the first strip plate frame 1 and the second strip plate frame 2.
[0032] Preferably, an external thread is provided on the outer wall of the pin 51, and an internal thread is provided on the inner wall of the locking hole 54 to connect with the external thread; compared with the simple plug-in type, the threaded locking has a much higher vibration resistance and is suitable for vibration environments such as workshop assembly lines, avoiding the pin from falling off and the structure from loosening due to vibration.
[0033] In this invention, handle notches 71 are provided on both the left and right sides of the first strip-shaped board frame 1 and the second strip-shaped board frame 2; workers can easily move a single strip-shaped board frame by holding the handle notch of the board frame with one hand, avoiding slippage due to the smooth surface of the board frame.
[0034] In this utility model, both the first strip plate frame 1 and the second strip plate frame 2 are made of antistatic material, preferably antistatic ABS plastic.
[0035] During production, a permanent antistatic agent (such as carbon black masterbatch) is added to the plastic raw material instead of being sprayed on the surface (to avoid the coating losing its antistatic effect after wear), ensuring long-term stable antistatic performance.
[0036] Based on the accompanying drawings and the foregoing display and description of the basic principles, main features, and advantages of this utility model, those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
