Description

Technical Field

[0001] This application relates to the technical field of display screen processing, and more particularly to a PCB material box. Background Technology

[0002] MLED (Mini LED and Micro LED) achieves finer image control and higher pixel density through tiny light-emitting diodes. It supports independent control of the brightness and color of each pixel, resulting in a more realistic visual experience compared to traditional LCD (Light Emitting Diode) and OLED (Organic Light-Emitting Diode) technologies. It excels in contrast, color gamut, and brightness, and can display deeper blacks and a wider color gamut.

[0003] Molding is an important step in MLED manufacturing. Multiple PCBs (Printed Circuit Boards) are usually stored in a box and processed by taking out the PCBs one by one and molding them separately.

[0004] In the prior art, the material boxes used to store PCB boards usually adopt a manual opening or closing self-locking switch, which is cumbersome to operate. Furthermore, if there are problems such as accidental touch, operation delay, or forgetting to operate, the risk of PCB boards falling off will increase, such as CN211568765U. Utility Model Content

[0005] One of the technical problems this application aims to solve is the issue of PCB boards easily falling off during the PCB loading and unloading process due to manual operation of the self-locking switch.

[0006] To address the aforementioned technical problems, this application provides a PCB material box.

[0007] A PCB box according to this application includes: a box assembly, which includes a box structure and a locking structure. The locking structure has a protrusion and is movably connected to the box structure. The PCB is disposed inside the box structure. The protrusion has a locked state close to the PCB and a locked state away from the PCB. An adjustment assembly includes a driving structure and a force-applying structure. The force-applying structure is connected to the driving structure and is correspondingly arranged with the locking structure.

[0008] In some embodiments, the drive structure includes a rotary cylinder, and the force-applying structure is connected to the rotary cylinder. The force-applying structure has a force-applying state close to the locking structure and a force-waiting state far from the locking structure.

[0009] In some embodiments, the force-applying structure includes a force-applying section and a guide section. The force-applying section is connected to a rotary cylinder, and the guide section is connected to the force-applying section. The guide section has an inclined surface, and the vertical height of the side of the inclined surface near the force-applying section is lower than that of the side of the inclined surface away from the force-applying section.

[0010] In some embodiments, the material box structure includes a connecting portion and a first side plate, the first side plate being connected to the connecting portion, the first side plate having a plurality of first grooves, the plurality of first grooves being spaced apart, and the PCB portion being located within the first groove.

[0011] In some embodiments, the first side plate has a mounting hole through which a plurality of first grooves pass, a locking structure is movably connected to the mounting hole, and a plurality of protrusions are provided, with the plurality of protrusions corresponding one-to-one with the plurality of first grooves.

[0012] In some embodiments, the hopper assembly further includes an elastic element disposed within a mounting hole and connected to the end of the locking structure away from the adjustment assembly.

[0013] In some embodiments, the material box structure further includes a second side plate, which is movably connected to the connecting portion. The second side plate has a plurality of second grooves, which are provided in a one-to-one correspondence with a plurality of first grooves.

[0014] In some embodiments, the connecting portion includes a guide rail connected to a first side plate and disposed perpendicular to the first side plate, a second side plate movably connected to the guide rail, and a second groove facing the first groove.

[0015] In some embodiments, the connecting part has an elongated hole, the length direction of which is parallel to the guide rail, and the second side plate has a threaded hole corresponding to the elongated hole, and a fastener passes through the elongated hole and connects with the threaded hole.

[0016] In some embodiments, the first groove has a first guide portion at both ends, and the width of the first guide portion decreases continuously along the direction from the end to the middle of the first groove; the second groove has a second guide portion at both ends, and the width of the second guide portion decreases continuously along the direction from the end to the middle of the second groove.

[0017] Through the above technical solution, the PCB material box provided in this application places multiple PCBs within the material box structure. A driving structure drives a force-applying structure to move, which in turn applies external force to a locking structure, causing the locking structure to move. The protrusions move closer to or further from the PCBs as the locking structure moves, thus switching between a locking state and a ready-to-lock state. The movement cycle of the driving structure is set according to the time interval between inserting or removing PCBs, thereby achieving automatic loading and unloading. The technical solution of this application effectively solves the problem in existing technologies where manual operation of the self-locking switch easily causes PCBs to fall during PCB loading and unloading.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] like Figures 1 to 7 As shown, the PCB material box disclosed in Embodiment 1 of this application includes: a material box assembly 10 and an adjustment assembly 20. The material box assembly 10 includes a material box structure 11 and a locking structure 12. The locking structure 12 has a protrusion 121. The locking structure 12 is movably connected to the material box structure 11. The PCB is disposed in the material box structure 11. The protrusion 121 has a locked state close to the PCB and a locked state away from the PCB. The adjustment assembly 20 includes a driving structure 21 and a force-applying structure 22. The force-applying structure 22 is connected to the driving structure 21. The force-applying structure 22 is correspondingly disposed to the locking structure 12.

[0036] Using the technical solution of Embodiment 1, multiple PCBs are placed inside the material box structure 11. The driving structure 21 drives the force-applying structure 22 to move, which in turn applies external force to the locking structure 12, causing it to move. The protrusion 121 moves closer to or further away from the PCB as the locking structure 12 moves, thus switching between the locking state and the ready-to-lock state. The movement cycle of the driving structure 21 is set according to the time interval between placing or removing the PCB, thereby achieving automatic loading and unloading. The technical solution of Embodiment 1 effectively solves the problem in the prior art where PCBs easily fall off due to manual operation of the self-locking switch during PCB loading and unloading.

[0037] It should be noted that the above-mentioned "the force-applying structure 22 and the locking structure 12 are correspondingly set" includes the case where the force-applying structure 22 and the locking structure 12 are connected and the case where the force-applying structure 22 and the locking structure 12 are not connected.

[0038] like Figures 1 to 3As shown, in the technical solution of Embodiment 1, the driving structure 21 includes a rotary cylinder 211, and a force-applying structure 22 is connected to the rotary cylinder 211. The force-applying structure 22 has a force-applying state close to the locking structure 12 and a force-waiting state away from the locking structure 12. Under the driving action of the rotary cylinder 211, the force-applying structure 22 rotates together with the output shaft of the rotary cylinder 211. As the force-applying structure 22 rotates, the end of the force-applying structure 22 away from the output shaft of the rotary cylinder 211 approaches or moves away from the locking structure 12. When the force-applying structure 22 approaches the locking structure 12, it applies an external force to the locking structure 12, and the locking structure 12 locks the PCB in the material box structure 11. When the force-applying structure 22 moves away from the locking structure 12, the locking structure 12 releases the PCB without affecting the normal loading and unloading of the PCB. The method of using a rotary cylinder 211 to control the movement of the force-applying structure 22 is relatively simple. By setting the rotation speed of the rotary cylinder 211 according to the time interval between loading and unloading, the automatic locking and opening of the material box assembly 10 can be achieved, ensuring stable loading and unloading movement and preventing PCB slippage.

[0039] like Figure 3 As shown, in the technical solution of Embodiment 1, the force-applying structure 22 includes a force-applying section 221 and a guide section 222. The force-applying section 221 is connected to the rotary cylinder 211, and the guide section 222 is connected to the force-applying section 221. The guide section 222 has an inclined surface 2221. The vertical height of the side of the inclined surface 2221 near the force-applying section 221 is lower than the side of the inclined surface 2221 away from the force-applying section 221. During the rotation of the force-applying structure 22, the side of the inclined surface 2221 furthest from the force-applying section 221 first contacts the locking structure 12. As the force-applying structure 22 continues to rotate, the inclined surface 2221 abuts against the locking structure 12, and the side of the inclined surface 2221 closer to the force-applying section 221 gradually approaches the locking structure 12. Due to the inclination of the inclined surface 2221, as the force-applying structure 22 rotates, the locking structure 12 is gradually pressed down by the inclined surface 2221, and the protrusion 121 moves closer to the PCB, locking the PCB board inside the material box assembly 10. The inclined surface 2221 avoids the problem that the force-applying structure 22 directly contacts the side of the locking structure 12 during rotation, applying only a horizontal force to the locking structure 12 without applying a vertical force, thus preventing the locking structure 12 from moving vertically.

[0040] like Figures 4 to 6 As shown, in the technical solution of Embodiment 1, the material box structure 11 includes a connecting part 111 and a first side plate 112. The first side plate 112 is connected to the connecting part 111. The first side plate 112 has a plurality of first grooves 1121, which are arranged at intervals. The PCB portion is located in the first groove 1121. The arrangement of the plurality of first grooves 1121 allows the PCBs to be separated, avoiding wear on the PCBs and facilitating individual loading and unloading of the PCBs.

[0041] like Figures 4 to 6 As shown, in the technical solution of Embodiment 1, the first side plate 112 has a mounting hole 1122 through which a plurality of first grooves 1121 are inserted. The locking structure 12 is movably connected to the mounting hole 1122. A plurality of protrusions 121 are provided, each corresponding to one of the plurality of first grooves 1121. The mounting hole 1122 is used to mount the locking structure 12. The axis of the mounting hole 1122 is parallel to the vertical direction. The locking structure 12 is movably disposed within the mounting hole 1122. As the locking structure 12 moves, the protrusions 121 enter or exit the corresponding first grooves 1121, thereby achieving the switching between a locked state and a ready-to-lock state.

[0042] like Figure 4 and Figure 5 As shown, in the technical solution of Embodiment 1, the material box assembly 10 further includes an elastic element, which is disposed in the mounting hole 1122 and connected to the end of the locking structure 12 away from the adjusting assembly 20. When the locking structure 12 is subjected to an external force from the force-applying structure 22, the locking structure 12 moves downward, compressing the elastic element, and the protrusion 121 approaches the PCB to lock the PCB; after the force-applying structure 22 moves away from the locking structure 12, under the elastic force of the elastic element, the locking structure 12 resets, the protrusion 121 moves away from the PCB, and becomes a locking state, at which time the PCB is loaded and unloaded.

[0043] like Figure 1 As shown, in the technical solution of Embodiment 1, the material box structure 11 further includes a second side plate 113, which is movably connected to the connecting part 111. The second side plate 113 has a plurality of second grooves 1131, which are arranged one-to-one with a plurality of first grooves 1121. As the second side plate 113 moves, the distance between the second grooves 1131 and the first grooves 1121 changes, thereby adapting to PCBs of different widths and improving versatility.

[0044] like Figure 1 As shown, in the technical solution of Embodiment 1, the connecting part 111 includes a guide rail 1111, which is connected to the first side plate 112 and is perpendicular to the first side plate 112. The second side plate 113 is movably connected to the guide rail 1111, and the second groove 1131 is arranged facing the first groove 1121. The guide rail 1111 guides the movement of the second side plate 113, preventing the position of the second side plate 113 from shifting, which could lead to misalignment between the first groove 1121 and the second groove 1131, causing problems such as twisting and deformation of the internal PCB.

[0045] like Figure 6As shown, in the technical solution of Embodiment 1, the connecting part 111 has an elongated hole 1112, the length direction of which is parallel to the guide rail 1111. The second side plate 113 has a threaded hole corresponding to the elongated hole 1112. A fastener passes through the elongated hole 1112 and connects to the threaded hole. Loosen the fastener, move the second side plate 113, and adjust the distance between the second side plate 113 and the first side plate 112. Pass the fastener through the elongated hole 1112 and tighten it with the threaded hole to fix the second side plate 113. Then, place it into the PCB to prevent the second side plate 113 from moving during use, which would increase the distance between the second side plate 113 and the first side plate 112 and cause the PCB to fall off.

[0046] like Figure 7 As shown, in the technical solution of Embodiment 1, the first groove 1121 has first guide portions at both ends, and the width of the first guide portions decreases continuously along the direction from the end to the middle of the first groove 1121. The second groove 1131 has second guide portions at both ends, and the width of the second guide portions decreases continuously along the direction from the end to the middle of the second groove 1131. The arrangement of the first guide portions and the second guide portions facilitates the insertion of the PCB into the interior of the first groove 1121 and the second groove 1131. The protrusion 121 locks the PCB by pressing both sides of the PCB into the first groove 1121 and the second groove 1131.

[0047] The difference between the technical solution of Embodiment 2 and that of Embodiment 1 is that the driving structure 21 includes a linear drive cylinder, and the force application structure 22 is connected to the locking structure 12. The linear drive cylinder drives the force application structure 22 to move in a linear direction, thereby causing the locking structure 12 to move in a linear direction. Since the force application structure 22 and the locking structure 12 are connected and move synchronously, there is no need to set up an elastic element in the technical solution of Embodiment 2, which further simplifies the structure.

[0048] In summary, adding a Festo DRRD series rotary cylinder to the loading and unloading platform, with adjustable buffer and clamping blocks supporting any angle from 0-190°, is beneficial for unlocking the material box self-locking switch and buffer plunger, connecting the clamping blocks to the cylinder, rotary cylinder, and electrical control system. The PLC programmable logic controller serves as the core, receiving signals from sensors and controlling the rotary cylinder's self-locking action. Photoelectric sensors detect the material box's position, pressure sensors confirm the locked state, and independent safety relays form an emergency stop circuit, immediately cutting off the locking power in abnormal situations. Expected benefits include: increased production efficiency (improved loading and unloading speed, reducing cycle time by 3-5 seconds); improved product quality (reduced frequency of PCB board drops due to manual control of the material box self-locking switch); and improved safety (eliminating the risk of accidental material box detachment, reducing operator intervention, and minimizing human error). Long-term maintenance plan includes weekly checks of mechanical component wear. In summary, this solution, through mechatronics design, achieves intelligent control of material box locking / unlocking, achieving an optimal balance in terms of safety, reliability, and economy. It can significantly improve the overall performance of the loading and unloading platform, lay the foundation for subsequent intelligent upgrades of the production line, effectively improve equipment production efficiency, and reduce the frequency of PCB boards falling due to manual operation.
