Description

Technical Field

[0001] The present invention relates to the technical field of workshop workpiece storage equipment, and particularly relates to a multi-layer circuit board blank storage device for a PCB processing station in a workshop. Background Art

[0002] Multi-layer printed circuit boards are the core basic carriers for signal transmission, power distribution, and electromagnetic compatibility in electronic devices. The production process needs to go through multiple processes such as drilling, lamination, etching, electroplating, etc. in sequence. There are a large number of temporary storage, nearby turnover, and short-distance transfer requirements between the workstations of each process. The blank storage device supporting the processing station is an important workshop auxiliary equipment for connecting the front and back processes, ensuring the production rhythm of the workshop, and standardizing the working environment of the workstations. Its performance directly affects the production efficiency of the production line and the quality stability of the in-process blanks.

[0003] At present, the storage of sideboard blanks at workstations in multi-layer circuit board production workshops is generally achieved by using ordinary turnover boxes or simple open shelving. To compress the space occupied by the workstations and adapt to the limited area around the operating table, the industry's conventional practice is to directly stack multiple blanks without isolation in the turnover box, and the surfaces of adjacent blanks are directly in contact. There is no independent positioning and isolation protection structure. Such storage carriers essentially belong to general packaging containers and are not specifically designed to adapt to the workshop workstation operation scenarios, the production rhythm of the production line, and the human-machine operation requirements.

[0004] In actual production applications, the above existing solutions have the following deficiencies: The ability to protect the quality of the blanks is insufficient. The surfaces of adjacent blanks stacked and stored are directly in contact, and relative sliding is likely to occur during transportation and picking and placing, resulting in scratches on the precision circuits on the surface of multi-layer boards, exposed copper foils, and peeling of the solder mask layer. In severe cases, it directly causes open circuits in the lines and leads to the scrapping of the entire board. Even slight copper exposure and solder mask layer damage will greatly reduce the corrosion resistance and insulation performance of the blanks, leaving long-term quality hidden dangers. At the same time, the blanks have no positioning constraints in the box, and horizontal movement and rigid collisions are likely to occur during transportation, which not only causes cracking and chipping of the board edges, but is more likely to cause peeling of the inner-layer copper foil and the substrate of the multi-layer board, cracking of the substrate, and damage to the interlayer interconnect structure, resulting in batch scrapping of the blanks. Secondly, the adaptability to workshop workstation operations is poor, resulting in low operation efficiency. When taking and placing single pieces in the stacked storage method, it is necessary to repeatedly sort and rummage, which cannot match the production rhythm of the processing equipment's continuous material output. The proportion of auxiliary operations is high, dragging down the production capacity of the workstations. The existing devices are not designed in a supporting layout with the material output end of the processing equipment, and the blanks cannot be orderly stored after being discharged, easily causing chaos of the materials at the workstations. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a multi-layer circuit board blank storage device for a PCB processing station in a workshop.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A multilayer circuit board material storage device adapted to PCB processing stations includes a processing equipment body installed in the production workshop, and a placement rack mechanism disposed at the output end of the processing equipment body for temporary storage of circuit boards. The placement rack mechanism includes a protective box, a placement box, a slide assembly, a locking assembly, a fixing plate, and a pushing assembly. The protective box is a rectangular box structure with an opening at one end, disposed at the output end of the processing equipment body. The interior of the placement box has a plurality of placement slots linearly arranged along its length for supporting the circuit boards. Each placement slot extends along the width direction of the placement box. The system includes: a sliding rail assembly located inside the protective box; a sliding box that slides into the protective box via the sliding rail assembly, which also provides load-bearing support and sliding guidance for the placement box; a locking assembly that locks the placement box to the protective box after it has fully slid into the protective box; two fixing plates located symmetrically on both sides of the placement box, extending along the length of the placement box; and a pushing assembly that drives the two fixing plates to move synchronously towards each other when the placement box slides into the protective box, clamping and fixing the plate material in the placement slot.

[0007] Preferably, anti-collision strips are connected to the corners of the protective box; The protective box is connected to four corners at the bottom and to a locking post at the top, which corresponds to the locking post. The locking post has a hole along its axis for easy insertion of the locking post. Several elastic plates are equidistantly connected around the axis of the locking post. The outer wall of the locking post has a stabilizing groove corresponding to the elastic plate.

[0008] Furthermore: one end of the placement box is connected to an annular sealing plate, and a sealing ring that is in contact with the protective box is connected to the annular sealing plate; The protective box is connected to a pressing chamber at the end away from its opening, and a pressing plate is slidably connected inside the pressing chamber along the length of the protective box. A pressing spring is connected between the pressing plate and the inner wall of the pressing chamber.

[0009] Based on the aforementioned solution: the locking assembly is located at one end of the placement box near the annular closed plate, and the locking assembly includes a rotating column, a rotating wheel, a hinged base, a transmission link, a telescopic rod, a trapezoidal pin block, and a guide block; The rotating column is inserted through the end of the placement box and is rotatably connected to the placement box. Two hinge bases, transmission rods, telescopic rods, trapezoidal pins, and guide blocks are provided. The two hinge bases are connected to the outer wall of the rotating column located inside the placement box, and are symmetrically arranged. The two trapezoidal pins are symmetrically arranged on both sides of the rotating column. One end of each of the two telescopic rods is connected to the two trapezoidal pins. The two guide blocks are connected to the inner wall of the placement box. The telescopic rod passes through the guide block and is slidably connected to it. A transmission rod is provided between the end of the telescopic rod away from the trapezoidal pin and the corresponding hinge base. Both ends of the transmission rod are rotatably connected to the end of the corresponding telescopic rod and the hinge base, respectively. A locking groove corresponding to each trapezoidal pin is connected to the inner wall of the protective box near its opening. The locking groove has a locking groove suitable for the trapezoidal pin to engage. The rotating wheel is coaxially connected to the end of the rotating column located outside the placement box. A reset chamber is connected to the side wall of the placement box near the rotating wheel and is coaxially arranged with the rotating column. The rotating column passes through the reset chamber, and a torsion spring is sleeved on the rotating column and located inside the reset chamber. The two ends of the torsion spring are respectively connected to the rotating column and the reset chamber.

[0010] Furthermore: the slide assembly includes two receiving components, which are symmetrically arranged inside the protective box. Each of the two receiving components includes a fixed track, an extension track, a fixing block, a supporting sleeve, an extension spring, and an extension shaft. The fixed track extends along the length of the protective box, one end of which is fixedly connected to the inner wall of the protective box. The fixed block is connected to the bottom of the fixed track. The axial direction of the extension shaft is consistent with the extension direction along the fixed track. One end of the extension shaft is fixedly connected to the fixed block. The support sleeve is slidably connected to the extension shaft. The extension track is fixedly connected to the support sleeve. A pushing protrusion is provided at the bottom of the end of the placement box near the annular closed plate.

[0011] As a further embodiment of the present invention: the fixing plate is provided with a side pressing part and an upper pressing part, one side of the side pressing part and one side of the upper pressing part are connected to form an L-shaped plate structure suitable for the corner of the plate. On the fixing plate, the openings of the side pressing part and the upper pressing part near the placement slot plate are connected with clamping pads that correspond one-to-one with the placement slot plate.

[0012] Meanwhile, elastic frames are provided on both sides of the placement box, and the two elastic frames correspond to two fixed plates respectively, with the fixed plates set on the elastic frames; The elastic frame includes a sliding shaft, a lifting frame, and a telescopic spring; wherein, there are two sliding shafts, each of which is fitted with a telescopic spring, and the lifting frame is connected to each of the two sliding shafts. The lifting frame extends along the height direction of the protective box, and one end of the lifting frame is slidably connected to the sliding shaft, while the other end is connected to the fixed plate.

[0013] As a preferred embodiment of the present invention: the lifting frame includes a fixed frame and a movable frame. One end of the fixed frame is slidably connected to a corresponding sliding shaft, and the other end is provided with a lifting groove. One end of the movable frame is connected to a sliding protrusion slidably connected to the lifting groove, and the other end is connected to the fixed plate. The fixed frames on the two lifting frames are connected to a stabilizing rod, and a guide sleeve is connected to the stabilizing rod. The movable frames on the two lifting frames are connected to an adjusting rod, and a guide shaft is connected to the adjusting rod. One end of the guide shaft passes through the guide sleeve and is slidably connected to the guide sleeve. An adjusting bolt is rotatably connected to the stabilizer bar, and a threaded block is connected to the adjusting rod. One end of the adjusting bolt passes through the threaded block and is threadedly connected to the threaded block. An adjusting wheel is coaxially connected to the end of the adjusting bolt away from the threaded block.

[0014] Meanwhile, the pushing assembly includes two pushing members, each corresponding to one of the two fixed plates. Each pushing member includes an active wedge block, a driven wedge block, and an adjusting guide rail. The active wedge block is disposed on the inner wall of the protective box. The adjusting guide rail is connected to the side of the fixed plate away from the placement slot plate and extends along the height direction of the placement box. The driven wedge block is slidably connected to the adjusting guide rail and can slide back and forth along the extension direction of the adjusting guide rail. The adjusting guide rail is connected to the adjusting rod through a movable support plate, and the driven wedge block is connected to the adjusting rod through a fixed support frame. One end of the active wedge extends from the body toward the end of the protective box with an opening, and its cross-sectional dimension perpendicular to the extension direction decreases uniformly and linearly, forming a guide mating inclined surface one. One end of the driven wedge extends from the body toward the end of the placement box away from the annular sealing plate, and its cross-sectional dimension perpendicular to the extension direction decreases uniformly and linearly, forming a guide mating inclined surface two. The guide mating inclined surface one and the guide mating inclined surface two are in movable contact.

[0015] As a preferred embodiment of the present invention: two adjusting bolts are respectively provided on the inner walls of both sides of the protective box. The two adjusting bolts are rotatably connected to the inner wall of the protective box through a shaft bracket. The two adjusting bolts correspond to two active wedges respectively. The adjusting bolts pass through the corresponding active wedges and are threadedly connected to the active wedges. The end of the adjusting bolt away from the active wedges passes through the protective box and is coaxially connected to an input spline. The inner wall of the protective box is provided with a linear guide rail corresponding to the active wedge block. The linear guide rail extends along the length of the protective box, and the active wedge block is slidably connected to the corresponding linear guide rail.

[0016] The beneficial effects of this invention are as follows: 1. This invention utilizes a linear array of placement slots along the length of the placement box to allow individual panels to be independently fitted into a single placement slot, achieving complete physical isolation between panels and eliminating direct contact between adjacent panels. Through a linkage design between the pushing component and the sliding action of the placement box, the inclined surfaces of the active and driven wedges engage during the sliding of the placement box into the protective box, synchronously driving the symmetrical fixing plates on both sides to move towards each other. This creates a synchronous clamping and fixing effect on all panels within the placement slots, achieving a locking effect upon pushing in. No additional manual clamping operation is required, thus preventing horizontal movement of the panels during transport and ensuring that the final quality of the panels is not affected. This also ensures orderly storage of the panels after discharge, preventing material clutter at the workstation.

[0017] 2. The slide assembly in this invention adopts a dual-track symmetrical support structure with a fixed track and a retractable extension track. When the placement box slides in, the extension track can retract synchronously with the placement box to form continuous support with the fixed track. When the placement box is pulled out, the extension track can automatically extend outward, providing stable support for the placement box throughout the process. This avoids the placement box from tilting or shaking due to the front end being suspended during the loading and unloading of the board, and prevents the board from falling out of the placement slot and colliding. This further improves the protection effect of the board throughout the entire process. Secondly, the pull-out placement box is suitable for the loading and unloading height and operating distance of workers standing at the workstation. Workers do not need to bend over or lean out, which meets the ergonomic requirements of the workshop and improves the efficiency of single-workstation operation.

[0018] 3. The locking assembly in this invention adopts a locking structure with synchronous engagement of double trapezoidal pins and an automatic reset design of torsion springs. After the placement box is fully slid in, it can be automatically locked. The wedge-shaped structure of the trapezoidal pins forms an anti-loosening locking effect. Even if the device is subjected to vibration or impact, it will not be accidentally unlocked, avoiding the problem of the board falling and being damaged due to the placement box accidentally sliding out during the transfer process. This structure does not require additional manual operation, adapts to the fast-paced process flow requirements of the workshop, reduces auxiliary operation time, and the unlocking operation is simple and convenient. The torsion spring can realize automatic reset after unlocking, which takes into account both operational efficiency and locking security.

[0019] 4. This invention protects the placement box with a protective box. The annular sealing plate at the end of the placement box, together with the sealing ring, can fit tightly against the opening end face of the protective box after the placement box is completely slid into the protective box, forming a completely sealed cavity inside the protective box. This effectively isolates dust, moisture, and corrosive acid and alkali gases from the workshop environment from entering the box, avoiding problems such as oxidation of copper foil on the board, moisture absorption and deterioration of the insulation layer, and degradation of substrate performance. This ensures the performance stability of the board during storage. Furthermore, the multi-unit stacking and locking structure allows for flexible configuration of storage capacity according to the workstation's production capacity, adapting to the batch temporary storage needs of different production lines without the need for additional customized workstation racks.

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] A multilayer circuit board material storage device adapted to PCB processing stations, such as Figures 1-12As shown, the equipment includes a main body 100 of processing equipment installed in the production workshop. This main body 100 is mainly used for processing circuit board materials for circuit board production. The main body 100 of processing equipment can perform processes such as drilling, etching, and pressing on the circuit board. Its structure and working principle are not described in detail. It also includes: a protective box 1, a placement box 2, a slide assembly 4, a locking assembly 3, a fixing plate 5, and a pushing assembly. The protective box 1 is a rectangular box structure with an opening at one end. It is fixedly installed on the side of the discharge end of the processing equipment body 100, serving as a temporary storage unit for the workstation. It directly receives the processed boards, achieving orderly storage upon discharge. Furthermore, to facilitate workers retrieving boards from the placement box 2, such as… Figure 1 As shown, several stacked protective boxes 1 can be placed on the workbench as a whole, improving the convenience of workers' operations in the workshop. Inside the placement box 2, several placement slots 56 for supporting sheet metal are linearly arrayed along its length. Each placement slot 56 extends along the width of the placement box 2. The placement box 2 serves as the direct support carrier for the sheet metal. A single sheet metal can be independently fitted into a single placement slot 56, achieving physical isolation between the sheet metals and thus avoiding frictional damage caused by direct contact between adjacent sheet metal surfaces. A slide assembly 4 is installed inside the protective box 1, allowing the placement box 2 to slide into the protective box 1 via the slide assembly 4. The slide assembly 4 is used to provide load-bearing support and sliding guidance for the placement box 2; the locking assembly 3 is used to lock and limit the placement box 2 and the protective box 1 after the placement box 2 is completely slid into the protective box 1; there are two fixing plates 5, which are located on both sides of the placement box 2 and are symmetrically arranged, and both fixing plates 5 extend along the length of the placement box 2; the pushing assembly is used to drive the two fixing plates 5 to move synchronously towards each other when the placement box 2 slides into the protective box 1, so that the two fixing plates 5 clamp and fix the plate material in the placement slot plate 56, realizing the linkage effect of locking as soon as it is pushed in, which greatly improves the stability of the plate material storage.

[0025] Specifically, anti-collision strips 6 are connected to the corners of the protective box 1, which can absorb the impact force generated by external collisions during the transportation and stacking of the device, prevent the deformation of the box from causing squeezing damage to the internal plates, and at the same time improve the service life of the device. The protective box 1 has four insertion posts 7 at the bottom corners and a locking post 8 corresponding to each insertion post 7 at the top. The locking post 8 has insertion holes 9 along its axis, which are suitable for the insertion of the insertion post 7. Several elastic pieces 10 are equidistantly connected around the axis of the insertion hole 9. The outer wall of the insertion post 7 has a stabilizing groove 11 corresponding to each elastic piece 10. When multiple devices are stacked, the insertion post 7 of the upper device can be directly inserted into the insertion hole 9 of the locking post 8 of the lower device. During the insertion process, the elastic piece 10 undergoes elastic deformation and gets stuck in the stabilizing groove 11 of the insertion post 7, realizing automatic locking of the upper and lower devices. This not only improves the space utilization of stacked storage, but also avoids the risk of the device sliding or tipping over during stacking, making it suitable for centralized storage of batches of sheet metal in the workshop.

[0026] Furthermore: One end of the placement box 2 is connected to an annular sealing plate 12, and a sealing ring is connected to the annular sealing plate 12 to make contact with the protective box 1. When the placement box 2 is completely slid into the protective box 1, the annular sealing plate 12 drives the sealing ring to fit tightly against the open end face of the protective box 1, so that the interior of the protective box 1 forms a sealed cavity, which isolates dust, moisture and acid and alkali corrosive gases in the workshop environment from entering the box, avoids the oxidation of copper foil of the board and the deterioration of insulation layer performance, and solves the problem of insufficient environmental protection of the existing open storage structure. The protective box 1 is connected to a pressing chamber 13 that communicates with its interior at the end away from its opening. A pressing plate 14 is slidably connected inside the pressing chamber 13 along the length of the protective box 1. A pressing spring 15 is connected between the pressing plate 14 and the inner wall of the pressing chamber 13.

[0027] When the placement box 2 slides into the protective box 1 to the end of its travel, the end of the placement box 2 will contact the pressing plate 14, pushing the pressing plate 14 to compress the pressing spring 15. On the one hand, the elastic force of the pressing spring 15 can buffer the sliding action of the placement box 2, avoiding a rigid collision between the placement box 2 and the inner wall of the protective box 1, thus protecting the sheet material from impact. On the other hand, when the locking assembly 3 is released, the rebound force of the pressing spring 15 can push the placement box 2 to slide out automatically for a certain distance, eliminating the need for manual prying by the operator and greatly improving the convenience of device operation.

[0028] The locking assembly 3 is located at one end of the placement box 2 near the annular closed plate 12. The locking assembly 3 includes a rotating column 16, a rotating wheel 17, a hinged base 18, a transmission link 19, a telescopic rod 20, a trapezoidal pin block 21, and a guide block 22. The rotating column 16 passes through the end of the placement box 2 and is rotatably connected to it. Two hinged bases 18, transmission connecting rods 19, telescopic rods 20, trapezoidal pins 21, and guide blocks 22 are each provided. The two hinged bases 18 are connected to the outer wall of the end of the rotating column 16 located inside the placement box 2, and the two hinged bases 18 are symmetrically arranged. The two trapezoidal pins 21 are symmetrically arranged on both sides of the rotating column 16. One end of each of the two telescopic rods 20 is connected to one of the two trapezoidal pins 21. The two guide blocks 22 are connected to the inner wall of the placement box 2. The rod 20 passes through the guide block 22 and is slidably connected to the guide block 22. A transmission link 19 is provided between the end of the telescopic rod 20 away from the trapezoidal pin 21 and the corresponding hinge base 18. The two ends of the transmission link 19 are rotatably connected to the end of the corresponding telescopic rod 20 and the hinge base 18, respectively. A locking groove block 23 corresponding to the trapezoidal pin 21 is connected to the inner wall of the protective box 1 near its opening. The locking groove block 23 is provided with a locking groove suitable for the trapezoidal pin 21 to move and engage. The rotating wheel 17 is coaxially connected to the end of the rotating column 16 located outside the placement box 2. A reset chamber 24, coaxially arranged with the rotating column 16, is connected to the side wall of the placement box 2 near the rotating wheel 17. The rotating column 16 passes through the reset chamber 24. A torsion spring 25 is sleeved on the rotating column 16 and is located inside the reset chamber 24. The two ends of the torsion spring 25 are connected to the rotating column 16 and the reset chamber 24, respectively.

[0029] After the placement box 2 is completely slid into the protective box 1, the trapezoidal pin 21 and the locking groove of the locking slot 23 are in a coaxial corresponding position. At this time, the return torque of the torsion spring 25 drives the rotating column 16 to maintain its initial position, so that the trapezoidal pin 21 is completely locked into the locking groove, realizing the automatic locking of the placement box 2 and the protective box 1 without additional manual operation, thus preventing the placement box 2 from accidentally sliding out during transportation. When it is necessary to remove the placement box 2, the operator rotates the rotating wheel 17, which drives the rotating column 16 to rotate synchronously. The rotating column 16 drives the transmission link 19 to swing through the hinged bases 18 on both sides. The transmission link 19 pulls the telescopic rod 20 to slide along the guide block 22 towards the rotating column 16, thereby driving the two sets of trapezoidal pins 21 to move synchronously towards each other, completely disengaging from the locking groove, and releasing the lock between the placement box 2 and the protective box 1. At this time, the pressing spring 15 in the pressing chamber 13 rebounds, pushing the placement box 2 to slide outward, making it convenient for the operator to remove.

[0030] The torsion spring 25 inside the reset chamber 24 can automatically drive the rotating column 16 to rotate and reset after the operator releases the rotating wheel 17, preparing for the next locking action. At the same time, the trapezoidal structure of the trapezoidal pin 21 can form a wedge-shaped locking effect when it is inserted into the locking groove. Even if the device is subjected to vibration or impact, the pin will not accidentally come out, which greatly improves the reliability of the locking structure and eliminates the hidden danger of accidental unlocking during transportation.

[0031] Furthermore: the slide assembly 4 includes two receiving components, which are symmetrically arranged inside the protective box 1. Each receiving component includes a fixed track 26, an extension track 27, a fixing block 28, a supporting slide sleeve 29, an extension spring 30, and an extension shaft 31. The fixed track 26 extends along the length of the protective box 1. One end of the fixed track 26 is fixedly connected to the inner wall of the protective box 1. The fixed block 28 is connected to the bottom of the fixed track 26. The axial direction of the extension shaft 31 is consistent with the extension direction along the fixed track 26. One end of the extension shaft 31 is fixedly connected to the fixed block 28. The support sleeve 29 is slidably connected to the extension shaft 31. The extension track 27 is fixedly connected to the support sleeve 29. A push protrusion is provided at the bottom of the end of the placement box 2 near the annular sealing plate 12.

[0032] As the placement box 2 slides into the protective box 1, one end of the placement box 2 first contacts the extension track 27. Under its own weight, the bottom of the placement box 2 abuts against the surface of the extension track 27, generating a large frictional force. When the placement box 2 slides into the protective box 1, it simultaneously drives the extension track 27 to overcome the axial elastic force of the extension spring 30 and move towards the fixed track 26 until the end of the extension track 27 abuts against the end of the fixed track 26. As the placement box 2 is continuously pushed, the protrusion on the placement box 2 will contact the extension track 27, assisting in pushing the extension track 27 to slide completely into the protective box 1 with the placement box 2. This ensures that the placement box 2 is in a stable, symmetrical support state with double tracks throughout the entire sliding process, without any risk of suspension or tilting.

[0033] When the placement box 2 is pulled out of the protective box 1, the rebound force of the extension spring 30 will push the support sleeve 29 to move along the extension shaft 31 toward the opening of the protective box 1, causing the extension track 27 to automatically extend outward, providing continuous support for the pulling action of the placement box 2, preventing the placement box 2 from tilting or shaking due to the front end being suspended during the pulling process, and preventing the board from falling out of the placement slot plate 56. At the same time, the structure of the double track symmetrical support can make the sliding process of the placement box 2 more stable, without jamming or deviation.

[0034] The fixing plate 5 is provided with a side pressing part 32 and an upper pressing part 33. One side of the side pressing part 32 and one side of the upper pressing part 33 are connected to each other to form an L-shaped plate structure suitable for the corner of the plate. On the fixing plate 5, the side pressing part 32 and the upper pressing part 33 are connected to clamping pads 34 corresponding to the placement groove plate 56 on the side openings of the fixing plate 5.

[0035] Both sides of the placement box 2 are provided with elastic frames, and the two elastic frames correspond to the two fixed plates 5 respectively. The fixed plates 5 are set on the elastic frames. The elastic frame includes a sliding shaft 35, a lifting frame 36, and a telescopic spring 37; there are two sliding shafts 35, and each sliding shaft 35 is fitted with a telescopic spring 37. The lifting frame 36 is connected to each sliding shaft 35. The lifting frame 36 extends along the height direction of the protective box 1, and one end of the lifting frame 36 is slidably connected to the sliding shaft 35, and the other end is connected to the fixed plate 5.

[0036] The lifting frame 36 includes a fixed frame 38 and a movable frame 39. One end of the fixed frame 38 is slidably connected to the corresponding sliding shaft 35, and the other end is provided with a lifting groove 40. One end of the movable frame 39 is connected to a sliding protrusion 41 that is slidably connected to the lifting groove 40, and the other end is connected to the fixed plate 5. The fixed frames 38 on the two lifting frames 36 are connected to a stabilizing rod 42. A guide sleeve 43 is connected to the stabilizing rod 42. The movable frames 39 on the two lifting frames 36 are connected to an adjusting rod 44. A guide shaft 45 is connected to the adjusting rod 44. One end of the guide shaft 45 passes through the guide sleeve 43 and is slidably connected to the guide sleeve 43. An adjusting bolt 46 is rotatably connected to the stabilizer bar 42, and a threaded block 47 is connected to the adjusting rod 44. One end of the adjusting bolt 46 passes through the threaded block 47 and is threadedly connected to the threaded block 47. An adjusting wheel 48 is coaxially connected to the end of the adjusting bolt 46 away from the threaded block 47.

[0037] During use, the operator can pre-adjust the clamping position of the fixing plate 5 according to the width and thickness specifications of the sheet material to be stored: rotating the adjusting wheel 48 drives the adjusting bolt 46 to rotate synchronously, and through the threaded transmission, the threaded block 47 moves along the axial direction of the adjusting bolt 46, thereby driving the movable frame 39 to slide up and down along the lifting groove 40 of the fixing frame 38, so that the upper pressing part 33 of the fixing plate 5 is matched with the upper surface of the sheet material. At the same time, the cooperation between the guide shaft 45 and the guide sleeve 43 can ensure that the lifting stroke of the movable frames 39 on both sides is completely consistent, avoiding the fixing plate 5 from tilting, ensuring that the clamping force on all sheets material is uniform, and there will be no problem of local clamping being too tight or too loose.

[0038] The telescopic spring 37 on the elastic frame provides elastic buffer margin when the fixed plate 5 clamps the sheet material. It can adapt to sheets of different thicknesses to achieve flexible clamping, avoiding edge cracking and substrate cracking caused by rigid clamping. When the device is subjected to vibration and impact, the deformation of the telescopic spring 37 absorbs vibration energy, further reducing the impact load on the sheet material. This solves the problem of sheet material movement, collision, and interlayer delamination caused by the lack of clamping structure in the prior art. At the same time, the L-shaped structure of the fixed plate 5 can form bidirectional limiting on the side and top surface of the sheet material. Combined with the flexible contact of the clamping pad 34, it can prevent the sheet material from moving horizontally and jumping vertically, restricting the displacement of the sheet material in all directions and greatly improving the stability of the sheet material during transportation.

[0039] The pushing assembly includes two pushing components, which are respectively set one-to-one with two fixed plates 5. The pushing components include an active wedge block 49, a driven wedge block 50, and an adjusting guide rail 51. The active wedge block 49 is set on the inner wall of the protective box 1. The adjusting guide rail 51 is connected to the side of the fixed plate 5 away from the placement slot plate 56. The adjusting guide rail 51 extends along the height direction of the placement box 2. The driven wedge block 50 is slidably connected to the adjusting guide rail 51 and can slide back and forth along the extension direction of the adjusting guide rail 51. The adjusting guide rail 51 is connected to the adjusting rod 44 through a movable support plate 52. The driven wedge block 50 is connected to the adjusting rod 44 through a fixed support frame 501. The adjusting guide rail 51 ensures that after the fixed plate 5 is adjusted, the driven wedge block 50 always corresponds to the active wedge block 49 and is on the same moving track. One end of the active wedge block 49 extends from the body toward the end of the protective box 1 with an opening. Its cross-sectional dimension perpendicular to the extension direction decreases linearly and forms a guide mating slope one. One end of the driven wedge block 50 extends from the body toward the end of the placement box 2 away from the annular sealing plate 12. Its cross-sectional dimension perpendicular to the extension direction decreases linearly and forms a guide mating slope two. The guide mating slope one and the guide mating slope two are in active contact.

[0040] Adjusting bolts 53 are provided on the inner walls of both sides of the protective box 1. Both adjusting bolts 53 are rotatably connected to the inner wall of the protective box 1 through the shaft bracket. The two adjusting bolts 53 correspond to the two active wedges 49 respectively. The adjusting bolts 53 pass through the corresponding active wedges 49 and are threadedly connected to the active wedges 49. The end of the adjusting bolts 53 away from the active wedges 49 passes through the protective box 1 and is coaxially connected to the input spline 54. The inner wall of the protective box 1 is provided with a linear guide rail 55 corresponding to the active wedge block 49. The linear guide rail 55 extends along the length of the protective box 1, and the active wedge block 49 is slidably connected to the corresponding linear guide rail 55.

[0041] During the process of the placement box 2 sliding into the protective box 1, the guide engagement slope 2 of the driven wedge block 50 first contacts the guide engagement slope 1 of the active wedge block 49. As the placement box 2 continues to move inward, the two slopes continue to abut and slide relative to each other. The active wedge block 49 generates a horizontal thrust on the driven wedge block 50 along the width direction of the placement box 2, pushing the driven wedge block 50 to drive the elastic frame and the fixed plate 5 to move synchronously towards the center of the placement box 2. This causes the fixed plates 5 on both sides to move synchronously towards each other, forming a clamping and fixing of all the plates in the placement slot plate 56. This achieves synchronous linkage between the sliding of the placement box 2 and the clamping of the plates, eliminating the need for additional manual clamping operations and greatly improving the operating efficiency of the device. Moreover, the structure of synchronous clamping on both sides can ensure that the plates are always in the center position of the placement slot plate 56, avoiding local stress damage caused by plate skewing.

[0042] The adjustable guide rail 51 ensures that after the operator adjusts the height of the fixed plate 5 using adjusting bolt 46, the driven wedge block 50 can still slide freely along the adjustable guide rail 51, always maintaining the same engagement height with the active wedge block 49. This guarantees the stability of the inclined engagement and prevents the clamping linkage function from being affected by the height adjustment of the fixed plate 5. Simultaneously, the operator can use an external tool in conjunction with the input spline 54 to rotate the adjusting bolt 53, driving the active wedge block 49 to move back and forth along the linear guide rail 55 via threaded transmission. This adjusts the initial position of the active wedge block 49, thereby changing the stroke of the inclined engagement and ultimately adjusting the clamping force and stroke of the fixed plate 5. This allows the device to adapt to plates of different widths, significantly improving its versatility.

[0043] like Figures 1-12 The following is the operating procedure of this device: First, place the preset number of protective boxes 1 at the discharge end of the main body 100 of the processing equipment to be used in the workshop. Then, according to the specifications and dimensions of the multi-layer circuit board material to be stored, first rotate the adjusting wheel 48, and drive the movable frame 39 to rise and fall through the adjusting bolt 1 46 to adjust the height of the fixed plate 5 so that the upper pressing part 33 of the fixed plate 5 is adapted to the upper surface of the board material. Then, rotate the adjusting bolt 2 53 through the input spline 54 to adjust the front and rear position of the active wedge block 49, set the clamping stroke and clamping force of the fixed plate 5, and complete the pre-adjustment.

[0044] Rotate the screw wheel 17 to release the locking assembly 3. Press the spring 15 in the press chamber 13 to rebound and push the placement box 2 outward along the slide assembly 4. Place the plates to be stored one by one into the placement slots 56 in the placement box 2. Each plate is independently fitted into a single placement slot 56 to achieve physical isolation.

[0045] The placement box 2 is pushed into the protective box 1 along the slide assembly 4. The placement box 2 first drives the extension track 27 to converge towards the fixed track 26 to form a continuous support track. During the sliding process, the inclined surfaces of the active wedge block 49 and the driven wedge block 50 cooperate to push the two fixed plates 5 to move synchronously towards each other, forming a flexible clamping and fixing of all the plates. When the placement box 2 is completely slid into the protective box 1, the annular sealing plate 12 drives the sealing ring to fit against the opening of the protective box 1 to form a sealed cavity. At the same time, the trapezoidal pin block 21 automatically engages in the locking groove of the locking slot block 23 under the action of the torsion spring 25, completing the locking of the placement box 2 and the protective box 1, realizing the fully automatic clamping and locking of the plates.

[0046] Rotating the turning wheel 17 causes the trapezoidal pin 21 to disengage from the locking groove, releasing the lock. Pressing the spring 15 pushes the placement box 2 outward. During the sliding process, the active wedge block 49 and the driven wedge block 50 disengage. The telescopic spring 37 rebounds and drives the fixing plate 5 to reset to both sides, releasing the clamping of the plate. The operator can then remove the plate from the placement groove plate 56.

[0047] When multiple devices are stacked, the insertion post 7 of the upper device is inserted into the insertion hole 9 of the locking post 8 of the lower device, and the elastic piece 10 is inserted into the stabilizing groove 11 to achieve automatic stacking and locking, thus completing the centralized storage of batch of sheet materials.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
