Technical Field

[0001] This utility model relates to the field of copper substrate blanking technology, and in particular to a stackable material box structure for blanking copper substrates of PCB boards. Background Technology

[0002] In the PCB manufacturing process, the copper substrate is a core conductive component. Its material unloading process requires orderly storage using stacked material boxes to ensure the continuity of subsequent processing and the quality of the substrate.

[0003] In the existing technology, after the material box is placed on the receiving table, it can usually only accommodate material boxes of a fixed size. When faced with material boxes of different widths, they cannot be placed because the spacing is too narrow, or they cannot fit the material box because the spacing is too wide, thus failing to meet the material cutting requirements of copper substrates of various specifications. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a stackable material box structure for cutting copper substrates for PCB boards. It aims to improve the problem that in the prior art, after the material box is placed on the receiving table, it can usually only accommodate material boxes of a fixed size. When faced with material boxes of different widths, the spacing is too narrow to accommodate them, or the spacing is too wide to fit the material boxes, thus failing to meet the cutting requirements of copper substrates of various specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stackable material box structure for unloading copper substrates of PCB boards, including a support platform and a receiving platform. Positioning plates are uniformly fixedly connected to the top of the receiving platform. Symmetrically arranged sliding grooves are uniformly opened inside the receiving platform. Guide rods are fixedly connected inside each sliding groove. A movable plate is slidably connected to the outer wall of each symmetrically arranged guide rod. The bottom of the movable plate is slidably connected to the sliding groove. A compression spring is symmetrically fixedly connected to one side of the movable plate. One end of each compression spring is fixedly connected to one side of the sliding groove. The inner wall of the compression spring is fitted onto the outer wall of the guide rod. A locking screw is threaded into the inside of the movable plate. The bottom of the locking screw abuts against the top of the receiving platform. An adjustment component is installed on the top of the receiving platform.

[0006] By adopting the above technical solution, the material box is placed between the positioning plate and the moving plate. When the material box is placed in, it pushes the moving plate to compress the spring. Then, the position of the moving plate is fixed by the locking screw. This can accommodate material boxes of different widths and effectively solve the problem that traditional receiving tables are difficult to be compatible with material boxes of various widths, thus improving the versatility and flexibility of the equipment.

[0007] Preferably, the length adjustment component includes multiple electric push rods, one side of each of the multiple electric push rods is fixedly connected to one side of the receiving platform, the output end of each electric push rod is fixedly connected to a movable plate, the receiving platform has symmetrically arranged rectangular slots evenly distributed inside, and the bottom of the movable plate is slidably connected to the symmetrically arranged rectangular slots.

[0008] Preferably, a cylinder is installed inside the support platform, a connecting plate is fixedly connected to the output end of the cylinder, support columns are uniformly fixedly connected to the top of the connecting plate, the top of the support columns is slidably connected to the top of the support platform, and the bottom of the receiving platform is fixedly connected to the top of the support columns.

[0009] Preferably, the top of each positioning plate is fixedly connected to a limiting rod, the outer wall of each limiting rod is slidably connected to a limiting ring, the inner thread of each limiting ring is connected to a limiting screw, and one end of the limiting screw is pressed against the outer side of the limiting rod.

[0010] Preferably, a fixing plate is fixedly connected to one side of the limiting ring, and a pressure sensor is installed at the bottom of the fixing plate.

[0011] Preferably, a sliding rod is slidably connected inside the fixed plate, a limit block is fixedly connected to the top of the sliding rod, a spring is fixedly connected to the bottom of the limit block, one end of the spring is fixedly connected to the top of the fixed plate, and the inner wall of the spring is fitted onto the outer wall of the sliding rod.

[0012] Preferably, a mounting base is fixedly connected to the bottom of the sliding rod, and a roller is rotatably connected inside the mounting base, with the pressure sensor located directly above the mounting base.

[0013] Preferably, an indicator light is installed on one side of the limiting rod, and the indicator light is electrically connected to the pressure sensor.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by placing a material box of the target width between the positioning plate and the moving plate, the side wall of the material box contacts the moving plate and pushes it to move away from the positioning plate. At this time, the moving plate slides along the outer wall of the guide rod and squeezes the compression spring. The compression spring is compressed and generates a reverse elastic force, so that the moving plate fits against the side wall of the material box. After the material box is completely placed and fits against the positioning plate and the moving plate, the locking screw inside the moving plate is rotated so that its bottom presses against the top of the receiving platform. At this time, the material box is stably clamped by the positioning plate and the moving plate, thus realizing the ability to adapt to material boxes of different widths.

[0016] 2. In this utility model, when the material box is stacked to a copper substrate, the cylinder is activated. The output end of the cylinder shortens and drives the receiving platform to move downward a certain distance, so that the material box moves down and the distance between the top of the substrate in the material box and the unloading track is kept at a certain distance. This avoids the substrate from falling and getting stuck due to excessive stacking, and realizes the up and down adjustment of the receiving platform to adapt to the change of stacking height of the copper substrate in the material box.

[0017] 3. In this utility model, by loosening the limiting screw on the limiting ring according to the height of the material box, the limiting ring is slid along the limiting rod to the target height, so that the roller is located inside the upper part of the material box. The limiting screw is then tightened to fix it. After the substrate stack rises and contacts the roller, it pushes the mounting base and sliding rod to move upward. The limiting block stretches the spring. When the material box is full, the mounting base squeezes the pressure sensor, and the signal is transmitted to the material receiving table control system, triggering the indicator light to light up and reminding the user to replace the material box. This realizes automatic monitoring and timely reminder of the material box's full state, effectively avoiding production problems caused by the material box being too full.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-2 , Figures 4-5 This utility model provides an embodiment of a stackable material box structure for unloading copper substrates of PCB boards, including a support platform 1 and a receiving platform 2. Positioning plates 201 are uniformly fixedly connected to the top of the receiving platform 2. Symmetrically arranged sliding grooves 202 are uniformly opened inside the receiving platform 2. Guide rods 203 are fixedly connected inside each sliding groove 202 of the receiving platform 2. A movable plate 204 is slidably connected to the outer wall of each symmetrically arranged guide rod 203. The bottom of the movable plate 204 is slidably connected inside the sliding groove 202. Compression springs 205 are symmetrically fixedly connected to one side of the movable plate 204. One end of each compression spring 205 is fixedly connected to one side of the sliding groove 202. The inner wall of the compression spring 205 is fitted onto the outer wall of the guide rod 203. A locking screw 206 is threadedly connected inside the movable plate 204. The bottom of the locking screw 206 abuts against the top of the receiving platform 2. An adjustment component is installed on the top of the receiving platform 2.

[0027] Specifically, in the initial state, the moving plate 204 maintains an initial distance from the positioning plate 201 under the elastic force of the compression spring 205. The material box of the target width is placed between the positioning plate 201 and the moving plate 204. The side wall of the material box contacts the moving plate 204 and pushes it to move away from the positioning plate 201. At this time, the moving plate 204 slides along the outer wall of the guide rod 203 and squeezes the compression spring 205. The compression spring 205 is compressed and generates a reverse elastic force, so that the moving plate 204 fits against the side wall of the material box. After the material box is fully placed and fits against the positioning plate 201 and the moving plate 204, the locking screw 206 inside the moving plate 204 is rotated so that its bottom presses against the top of the receiving table 2. The position of the moving plate 204 is locked by friction. At this time, the material box is stably clamped by the positioning plate 201 and the moving plate 204, and the width is adapted. This enables the device to adapt to material boxes of different widths, effectively solving the problem that the traditional receiving table 2 is difficult to be compatible with material boxes of various widths, and improving the versatility and flexibility of the equipment.

[0028] Reference Figure 1 , Figures 4-5The length adjustment component includes multiple electric push rods 3, one side of each electric push rod 3 is fixedly connected to one side of the receiving platform 2, and the output end of the electric push rod 3 is fixedly connected to a movable plate 301. The receiving platform 2 has symmetrically arranged rectangular slots 302 evenly distributed inside, and the bottom of the movable plate 301 is slidably connected in the symmetrically arranged rectangular slots 302.

[0029] Specifically, when it is necessary to adapt to material boxes of different lengths, after the width of the material box is fixed, the electric push rod 3 is activated. The output end of the electric push rod 3 extends and pushes the movable plate 301 to slide away from the electric push rod 3 along the rectangular groove 302. When the movable plate 301 moves to one side, the electric push rod 3 is turned off, thereby fixing the material boxes of different lengths and further enhancing the adaptability of the equipment to material boxes of different specifications.

[0030] Reference Figure 2 The support platform 1 is equipped with a cylinder 4. The output end of the cylinder 4 is fixedly connected to a connecting plate 401. The top of the connecting plate 401 is evenly fixedly connected to a support column 402. The top of the support column 402 is slidably connected to the top of the support platform 1. The bottom of the receiving platform 2 is fixedly connected to the top of the support column 402.

[0031] Specifically, as the stacking height of the copper substrates in the material box changes, in the initial state, the cylinder 4 is in the extended state, and the top of the support column 402 drives the receiving platform 2 to the highest position. At this time, the bottom end of the material box and the unloading end are on the same horizontal line with no substrate inside.

[0032] When the material box is stacked to a copper substrate, cylinder 4 is activated. The output end of cylinder 4 shortens and drives the receiving platform 2 to move downward a certain distance, so that the material box moves down and the distance between the top of the substrate in the material box and the unloading track is kept at a certain distance. This prevents the substrate from falling and getting stuck due to excessive stacking, and realizes the up and down adjustment of the receiving platform 2 to adapt to the change in the stacking height of the copper substrate in the material box.

[0033] Reference Figures 1-5 Each positioning plate 201 has a fixed connection to a limiting rod 5 on its top. Each limiting rod 5 has a sliding connection to a limiting ring 501 on its outer wall. The limiting ring 501 has a limiting screw 502 connected to its internal thread. One end of the limiting screw 502 is pressed against the outside of the limiting rod 5.

[0034] A fixing plate 503 is fixedly connected to one side of the limiting ring 501, and a pressure sensor 504 is installed at the bottom of the fixing plate 503.

[0035] A sliding rod 505 is slidably connected inside the fixed plate 503. A limit block 506 is fixedly connected to the top of the sliding rod 505. A spring 507 is fixedly connected to the bottom of the limit block 506. One end of the spring 507 is fixedly connected to the top of the fixed plate 503. The inner wall of the spring 507 is fitted onto the outer wall of the sliding rod 505.

[0036] The bottom of the sliding rod 505 is fixedly connected to the mounting base 508, and the roller 509 is rotatably connected inside the mounting base 508. The pressure sensor 504 is located directly above the mounting base 508.

[0037] An indicator light 6 is installed on one side of the limit rod 5, and the indicator light 6 is electrically connected to the pressure sensor 504.

[0038] Specifically, based on the height of the material box, loosen the limiting screw 502 on the limiting ring 501, allowing the limiting ring 501 to slide along the limiting rod 5 to the target height, so that the roller 509 is just above the inside of the material box. Then tighten the limiting screw 502 to fix the position of the limiting ring 501. As copper substrates continuously fall into the material box, the stacking height gradually increases. When the top of the substrate contacts the roller 509, the continuing stacked substrates will push the roller 509 upward. After being subjected to force, the roller 509 drives the mounting base 508 to move upward. The mounting base 508 pushes the sliding rod 505 to slide along the inside of the fixing plate 503. The top of the sliding rod 505 is limited. The position block 506 rises synchronously and stretches the spring 507. The spring 507 generates a reverse pulling force, causing the roller 509 to adhere to the top of the substrate. When the substrate is stacked to the full height of the material box, the top of the mounting base 508 presses the pressure sensor 504. After the pressure sensor 504 detects the pressure signal, it transmits the signal to the control system of the receiving table 2. The control system triggers the indicator light 6 to light up, reminding the staff to replace the material box in time. This realizes automatic monitoring and timely reminder of the full status of the material box, effectively avoiding production problems caused by the material box being too full. The specific model of the pressure sensor 504 is DF9-40.

[0039] Working principle: Place the target width material box between the positioning plate 201 and the moving plate 204. The side wall of the material box pushes the moving plate 204 to slide along the guide rod 203 and squeezes the compression spring 205. After they fit together, rotate the locking screw 206 to press against the receiving table 2 and lock the moving plate 204 to complete the width adaptation.

[0040] After the width is fixed, start the electric push rod 3. Its output end pushes the movable plate 301 to slide along the rectangular groove 302 away from the electric push rod 3. After it is in place, turn off the electric push rod 3 to complete the length fixing.

[0041] Initially, cylinder 4 extends, and support column 402 drives receiving platform 2 to the highest position, with the bottom of the material box and the unloading end at the same level; for each copper substrate stacked, the output end of cylinder 4 shortens, and receiving platform 2 moves down a certain distance, so that the top of the substrate and the unloading track maintain a fixed distance.

[0042] According to the height of the material box, loosen the limiting screw 502 on the limiting ring 501, slide the limiting ring 501 along the limiting rod 5 to the target height, so that the roller 509 is located inside the upper part of the material box, tighten the limiting screw 502 to fix it, after the substrate stack rises and contacts the roller 509, push the mounting base 508 and the sliding rod 505 to move upward, the limiting block 506 stretches the spring 507, when the material box is full, the mounting base 508 squeezes the pressure sensor 504, the signal is transmitted to the control system of the receiving table 2, triggering the indicator light 6 to light up, reminding to replace the material box.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
