[0002] With the rapid development of society and the economy, the types and quantities of electronic devices are increasing daily, and electronic products have penetrated into all aspects of our lives. Among these electronic products, PCBs (Printed Circuit Boards) support the operation of various complex circuits. However, existing SMT and related industries have many shortcomings in PCB material handling.

[0003] Due to the wide variety of board material types and sizes, switching between production models becomes quite cumbersome. Furthermore, the existing SMT material baskets have open inlet and outlet designs, easily leading to material spillage. During manual handling or transfer, boards are frequently damaged by impacts. Simultaneously, because some production processes involve overall heating, the original standard SMT material baskets cannot meet the requirements for overall baking, and existing baskets cannot achieve fully automated production. This not only restricts equipment development but also significantly reduces production efficiency. This utility model proposes a new solution to address these problems. Utility Model Content

[0046] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] The first aspect of this application, as Figures 1-6 As shown, a sheet metal box 100 is provided, including at least two side plates 11, a top plate 12, a bottom plate 13, and a blocking member 3. The inner side walls of the two oppositely arranged side plates 11 are symmetrically provided with multiple layers of plate grooves 111 from top to bottom. The plate grooves 111 are used to accommodate sheet metal 300. The top plate 12 is used to connect the upper side of the two adjacent side plates 11, and the bottom plate 13 is used to connect the lower side of the two adjacent side plates 11. The blocking member 3 is inserted through the end of the side plate 11. The blocking member 3 includes a first position and a second position. When the blocking member 3 is in the first position, the blocking member 3 is located on the movement trajectory of the sheet metal 300 entering and exiting the plate groove 111 to form a stop. When the blocking member 3 is in the second position, the blocking member 3 and the plate groove 111 are staggered to release the channel of the plate groove 111.

[0048] The sheet metal box 100 provided in this embodiment includes at least two side plates 11, a top plate 12, a bottom plate 13, and a blocking member 3. The blocking member 3 realizes the automatic feeding and discharging switch function of the sheet metal box 100, which can effectively prevent the sheet metal 300 from falling out during automatic transfer, facilitates the storage and handling of the sheet metal 300, and improves the level of production automation and production efficiency.

[0049] The sheet metal box 100 is made entirely of high-temperature resistant metal or metal alloy materials, ensuring its durability during high-temperature baking and improving the level of automation and production efficiency.

[0050] Furthermore, the inner side of the side plate 11 is precision-machined to form multiple parallel grooves 111, the depth of each groove 111 matching the thickness of the plate 300, ensuring that the plate 300 does not wobble after insertion. Furthermore, the top plate 12 connects the upper sides of two adjacent side plates 11, while the bottom plate 13 connects the lower sides of two adjacent side plates 11. The top plate 12 and bottom plate 13 serve to fix the side plates 11, improving the overall structural stability.

[0051] When the blocking member 3 is in the blocking state, that is, when the blocking member 3 is in the first position, the elastic member pushes the flange 311 of the blocking member 3 into the channel of the plate groove 111, and the plate 300 is blocked from sliding out. When the blocking member 3 is in the releasing state, that is, when the blocking member 3 is in the second position, the blocking member 3 is pressed down by external force to align its groove with the plate groove 111, and the plate 300 can move freely in and out. After the external force is removed, the elastic member can automatically bounce the blocking member 3 back to the first position to form the blocking state.

[0052] The board box 100 provided in this embodiment effectively prevents the board 300 from accidentally slipping during transportation or stacking through the automatic locking mechanism of the blocking component 3, reducing the risk of damage. The overall material selection of the board box 100 takes into account the high temperature resistance characteristics, which can meet the requirements of PCB baking process. The multi-layer board groove 111 and the stackable structure significantly improve the storage and transfer density and improve production efficiency.

[0053] like Figure 13 As shown, the height of the side plate 11, the layer height of the plate groove 111, and the height of the blocking member 3 of the plate box 100 can all be adjusted according to actual needs. By replacing the blocking rod 31 with different heights, it can be adapted to the side plate 11 with different heights. By replacing the blocking rod 31 with different flange spacing, it can be adapted to the plate 300 with different thicknesses, which increases the flexibility and expandability of the box.

[0054] In one possible implementation, such as Figures 1-12 As shown, a through hole is provided on the side plate 11, which passes through several plate grooves 111 and is located at the end of the side plate 11.

[0055] The side plate 11 has through holes at both ends for installing the blocking component 3 assembly. Figure 5 and Figure 6 As shown, the blocking member 3 can be made of stainless steel cylinder. The surface of the blocking member 3 is provided with an annular flange 311 and an annular concave flange 312, and automatic reset is achieved by pressing with an elastic element.

[0056] In one possible implementation, such as Figure 5 and Figure 6 As shown, the blocking component 3 includes a blocking rod 31, a blocking cap 32, a spring 33, and a plug 34. The blocking rod 31 passes through the through hole, the blocking cap 32 is located at the top of the blocking rod 31, and the outer diameter of the blocking cap 32 is larger than the inner diameter of the through hole. The spring 33 is sleeved on the blocking rod 31, the first end of the spring 33 contacts the blocking cap 32, and the second end of the spring 33 contacts the side plate 11. The spring 33 applies a spring force to the blocking cap 32 to move it away from the side plate 11. The plug 34 is located at the bottom of the blocking rod 31, and the outer diameter of the plug 34 is larger than the inner diameter of the through hole.

[0057] The blocking rod 31 passes through the through hole of the side plate 11. The top of the blocking rod 31 is fixed to the blocking cap 32 by threads or clips, and the bottom of the blocking rod 31 is fitted with a plug 34. The elastic element can be a spring 33, which is sleeved on the upper side of the blocking rod 31 and located between the side plate 11 and the blocking cap 32. The two ends of the spring 33 abut against the blocking cap 32 and the side plate 11 respectively, forming a pre-compression state. It can be understood that the blocking cap 32 and the plug 34 have an outer diameter larger than the through hole, forming a bidirectional limit to ensure that the blocking component 3 will not detach from the side plate 11 during movement.

[0058] This embodiment provides a specific structure of the blocking component 3. The bidirectional limiting design of the blocking cap 32 and the plug 34 avoids the risk of loss of the blocking component 3. The preload of the spring 33 ensures the automatic recovery capability of the blocking state. The single-point pressing type simplifies the operation. Only vertical force is needed to trigger the state switching. The modular components support quick disassembly and assembly. When damaged, vulnerable parts such as the blocking rod 31 and the spring 33 can be replaced separately.

[0059] In one possible implementation, such as Figure 5 and Figure 6 As shown, the blocking rod 31 includes a flange 311 and a concave flange 312. The flanges 311 are arranged sequentially along the axial direction of the blocking rod 31. The distance between the flanges 311 is adapted to the distance between the plate grooves 111. An inwardly recessed concave flange 312 is formed between adjacent flanges 311. The height of the concave flange 312 is adapted to the height of the plate groove 111. The blocking member 3 adopts a cylindrical rod structure. The rod body is machined with alternating flanges 311 and concave flanges 312. The flanges 311 are aligned with the plate groove 111 to form a physical stop for the plate material 300 in the plate groove 111. When an external force drives the blocking member 3 to move downward axially, the concave flange 312 aligns with the plate groove 111, thus releasing the passage of the plate groove 111.

[0060] Among them, such as Figure 11 and Figure 12 As shown, when the blocking member 3 is in the first position, the flange 311 is aligned with the plate groove 111, forming a stop for the plate material 300 entering and exiting the plate groove 111; when the blocking member 3 is in the second position, the concave flange 312 is aligned with the plate groove 111, releasing the plate groove 111 channel to allow the plate material 300 to enter and exit.

[0061] Among them, such as Figure 11 As shown, in its natural state, i.e., when the blocking member 3 is in the first position, the spring 33 pushes the blocking cap 32 upward, causing the blocking rod 31 to rise as a whole. At this time, the plug 34 closes the lower end of the through hole, and several flanges 311 in the middle of the blocking rod 31 are embedded in the plate groove 111 to form a physical stop; as Figure 12 As shown, in the working state, that is, when the blocking member 3 is in the second position, the external force presses down the blocking cap 32, compresses the spring 33 to move the blocking rod 31 down, and the plug 34 disengages from the lower end of the through hole. At the same time, several concave edges 312 of the blocking rod 31 align with the plate groove 111 channel, and the blocking state is released.

[0062] In one possible implementation, the blocking member 3 is disposed at one end of the side plate 11, and the blocking members 3 on the two oppositely disposed side plates 11 are disposed in opposite directions.

[0063] Among them, such as Figure 4 As shown, the number of blocking elements 3 is not less than the number of side plates 11. The number of blocking elements 3 can be at least two, and the two blocking elements 3 are respectively set on different side plates 11 and located at both ends of the board groove 111. They can limit the movement of the board material 300 in both directions along the board groove 111. The blocking elements 3 are installed in a mirror symmetrical manner on adjacent side plates 11. The blocking elements 3 of one side plate 11 are set to one side, and the blocking elements 3 of the opposite side plate 11 are set to the other side, forming a two-way interlocking structure. Each board groove 111 is equipped with independent blocking elements 3 at both ends to ensure that the two-way limiting function is independently controllable. The two-way blocking design eliminates the risk of board material 300 moving around, which is particularly suitable for the automated transmission needs of high-precision PCB boards.

[0064] It is understandable that, such as Figure 7 As shown, the number of side panels 11 can be two, three or other integers. Different numbers of side panels 11 can be freely combined according to actual needs. Each side panel 11 has an integrated blocking part 3 at the end, which supports quick disassembly and maintenance.

[0065] Understandably, when there are two side panels 11, they can be produced as identical standard parts, reducing production costs.

[0066] In one possible implementation, such as Figure 4 As shown, the top plate 12 and / or the bottom plate 13 are provided with marking parts 121. There can be multiple marking parts 121. That is, a flat marking area is reserved in the non-functional area of ​​the top plate 12 and / or the bottom plate 13 for the QR code label to be pasted or laser engraved. The marking parts 121 can be slightly recessed in the edge area to form a guard to prevent the label from shifting and falling off.

[0067] In one possible implementation, such as Figure 4 As shown, the top plate 12 is provided with an indicator sign 122, which indicates the flow direction of the sheet material 300 into and out of the plate groove 111. The indicator sign 122 can be set in the area of ​​the top plate 12 directly above the inlet of the plate groove 111. The arrow points to the direction of the sheet material 300 entering the plate groove 111. The double arrow can eliminate misjudgment of direction, reduce the risk of reverse loading of the sheet material 300, and visual guidance reduces the operator's path confirmation time and improves the efficiency of the action connection of the sheet material 300 entering and exiting the plate groove 111.

[0068] In one possible implementation, at least one of the top plate 12, side plate 11 and bottom plate 13 is provided with a weight-reducing groove 113.

[0069] Among them, the side plate 11 can be provided with an array of waist-shaped grooves, and the two ends are designed with arc transition structures to significantly reduce the risk of stress concentration. Other shapes of weight-reducing grooves 113, such as wave-shaped continuous grooves, can also be used.

[0070] Several weight-reducing grooves 113 can also be provided on the top plate 12 and the bottom plate 13. Under the premise of ensuring structural rigidity, they can not only reduce weight, but also prevent interference when the plate boxes 100 are stacked.

[0071] In one possible implementation, such as Figures 1-4 As shown, the top plate 12 is provided with a protruding gripping head 2. The gripping head 2 is used for gripping and transferring by the robotic arm. The gripping head 2 is locked to the top plate 12 by pins and screws, which can meet the gripping requirements of the robotic arm of the AGV / OHT crane. The gripping head 2 is located in the center of the top plate 12, forming a torque balance point when gripping, which effectively suppresses the swaying of the plate 300 during the transfer process.

[0072] The second aspect of this application, as Figures 8-12 As shown, an assembly-type sheet metal container is provided, including at least two sheet metal boxes 100 according to any one of the first aspects, the sheet metal boxes 100 being stackable.

[0073] The modular sheet metal container provided in this embodiment allows for boltless and rapid assembly and stacking of the upper and lower side panels 11 when at least two sheet metal boxes 100 are stacked vertically. The side panels 11 can be detachably connected by screws.

[0074] In one possible implementation, such as Figure 4 and Figure 8 As shown, the upper and lower ends of the side plate 11 are respectively provided with matching protrusions 112 and grooves. The protrusions 112 can be embedded in the grooves, and the height of the protrusions 112 is not lower than the height of the blocking member 3 in the first position.

[0075] The height of the protrusion 112 matches the depth of the groove, ensuring the stability of the sheet metal box 100 when stacked and transported, and allowing multiple layers to be stacked without screws.

[0076] In one possible implementation, such as Figure 4 and Figure 8 As shown, the bottom of the side plate 11 is provided with screw holes, and the top of the side plate 11 has corresponding screw holes on the protrusion 112. When the plate boxes 100 are stacked, they can be detachably connected by screws.

[0077] The convex strip 112 can be provided with several screw holes, and the corresponding screw holes are provided in the groove on the inner side of the side plate 11. When tightening the screws, the number of sheet materials 300 placed in the sheet material box 100 is doubled according to the stacking quantity. The stacked sheet material boxes 100 become an independent unit for use, which facilitates the improvement of storage density and production efficiency.

[0078] In one possible implementation, when the sheet metal box 100 includes a clamping head 2, a relief groove 131 for avoiding the clamping head 2 is provided on the bottom plate 13.

[0079] Among them, such as Figure 8 and Figure 12 As shown, the base plate 13 is provided with a clearance groove 131 corresponding to the clamping head 2. The depth of the clearance groove 131 needs to be greater than the maximum stroke height of the clamping head 2 to ensure that the base plate 13 of the upper board box 100 completely avoids the clamping head 2 of the lower board box 100 when stacking, and to ensure that the clamping head 2 of the lower board box 100 does not interfere with the board material 300 stored in the upper board box 100. This enables the vertical stacking of multiple board boxes 100, and the blocking functions do not interfere with each other after stacking. The clamping head 2 has a standardized structural design and is compatible with most automated handling equipment.

[0080] In one possible implementation, such as Figures 8-12As shown, when the sheet metal boxes 100 are stacked vertically, the blocking member 3 of the upper sheet metal box 100 contacts the blocking member 3 of the lower sheet metal box 100. When at least two sheet metal boxes 100 are stacked vertically, the blocking members 3 of the upper and lower sheet metal boxes 100 form rigid contact. When an external force presses down on the upper blocking member 3, the upper blocking member 3 moves downward, pushing the lower blocking member 3 to move synchronously, ensuring the synchronicity of mechanical activities and ensuring that the stacking of the boxes does not affect the switching function of blocking the entry and exit of the sheet metal 300.
