Description

Technical Field

[0001] This utility model relates to the field of material unloading and storage devices, specifically to a PCB board unloading and storage device. Background Technology

[0002] In the electronics manufacturing industry, PCB boards are core components of electronic devices, and the efficiency of their production process and the stability of product quality are crucial. As the final stage of PCB board production, material handling and storage directly impact the smoothness of subsequent warehousing, transportation, and quality inspection processes, playing a key role in reducing production losses and improving overall production efficiency.

[0003] However, the current PCB board cutting and storage devices still have many technical defects. Traditional cutting platforms are mostly fixed horizontally set up and lack flexible lifting and adjustment structures. Although some cutting and storage devices are equipped with lifting functions, existing cutting and storage devices lack optimized design of the cutting space during the storage process. They cannot form a suitable storage environment according to the structural characteristics of the PCB board, which makes the PCB board prone to shaking and displacement during the cutting process, further reducing the stability and reliability of the storage.

[0004] Therefore, developing a material unloading and storage device that can achieve flexible lifting and adjustment and stably store PCB boards with protruding parts has become an urgent need to solve current technical pain points and improve PCB board production efficiency. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a PCB board unloading and storage device.

[0006] The technical solution of this utility model is as follows: A PCB board unloading and storage device includes a lifting device and a support platform. The lifting device moves the support platform up and down. The support platform has a first inclined surface and a second inclined surface to form an unloading space with an upward angle.

[0007] Preferably, the first inclined plane is set perpendicular to the second inclined plane.

[0008] Preferably, the height of the second inclined plane is less than that of the first inclined plane.

[0009] Preferably, the top of the second inclined surface is provided with two symmetrical grooves.

[0010] Furthermore, the storage device includes a fixed plate, and a support platform is movably connected to one side of the fixed plate via a lifting device so that it can move along the height direction of the fixed plate.

[0011] Preferably, the bottom of the support platform is provided with an edge, and the device is provided with a pressing mechanism on one or both sides near the lifting device, with the bottom end of the pressing mechanism corresponding to the bottom edge of the storage device.

[0012] Preferably, the support platform includes a support plate and a drive plate, the lifting device is connected to the drive plate, and the top of the drive plate is provided with connecting frames on both sides, and the support plate is installed on the connecting frames.

[0013] Furthermore, there is a gap between the inner side of the support plate and the top of the drive plate, and the gap is provided with a first sensor for detecting the feeding.

[0014] Furthermore, two opposing tripods are provided, one side of which is fixedly connected to the drive plate, and the other side of which is fixedly connected to the connecting frame.

[0015] Furthermore, the connecting frame is provided with a limiting protrusion, the support plate is provided with a limiting hole corresponding to the limiting protrusion, and the top of the support plate also includes partition plates arranged in a rectangle.

[0016] The advantages of this utility model based on the above solution are as follows: This utility model achieves precise height adjustment by driving the support platform through a lifting device. The support platform can be adjusted in real time according to the thickness difference of PCB boards of different specifications, the fluctuation of the unloading position in the production process, and other scenario requirements. Furthermore, the support platform forms an upward-angled unloading space through the first and second inclined surfaces. When storing PCB boards with protruding components such as capacitors, resistors, and lenses, the hardware side edge of the PCB board can be precisely matched to the angle between the two inclined surfaces. The angled structure provides bidirectional limiting support for the PCB board edges. Compared to the planar contact of a horizontal platform, the angled fit increases the contact area between the PCB board and the support platform, improving the placement stability of each PCB board. Simultaneously, during multi-layer stacking, the edges of each PCB board are positioned via the angled section, preventing stacking tilt and wobbling caused by differences in the height of protruding components. This ensures the stability of the overall stacking structure, reduces product loss due to improper storage, and improves production yield. Attached Figure Description

Example 1

[0027] like Figure 1As shown, the unloading workshop includes an overall frame 100, a conveying platform 400 installed inside, a robot arm 200, and an unloading and storage device 300 on one side. The conveying platform 400 is located on one side of the overall frame 100, and the robot arm 200 is installed on the other side. A fixing plate 110 is provided next to the robot arm 200, and the unloading and storage device 300 is horizontally installed on the other side of the fixing plate 110.

[0028] like Figure 1 and Figure 2 As shown, a PCB board unloading and storage device 300 is disposed on the fixed plate 110, including two horizontally symmetrically arranged lifting mechanisms 310 and a support platform 320. The lifting mechanisms 310 are movably connected to the support platform 320 so that the support platform 320 can move vertically along the height direction of the fixed plate 110. A robot arm 200 is provided on one side of the storage device. The robot arm 200 is used to transfer the PCB board 500 to the support platform 320 so as to reduce the stacking height of the PCB board 500 while unloading.

[0029] The support platform 320 includes a first inclined surface 321 and a second inclined surface 322, which form an upward-angled unloading space. The robot arm 200 places the PCB board 500 obliquely onto the support platform 320. This oblique placement includes: placing it parallel to the first inclined surface 321 with the bottom of the PCB board 500 touching the second inclined surface 322; or placing it perpendicular to the first inclined surface 321 with the bottom of the PCB board 500 touching the second inclined surface 322. The first inclined surface 321 and the second inclined surface 322 are perpendicular to each other; the height of the second inclined surface 322 is less than that of the first inclined surface 321; and two grooves 323 are symmetrically provided on the top of the second inclined surface 322. In the angled structure formed by the first inclined surface 321 and the second inclined surface 322, the second inclined surface 322 is closer to the robot arm 200, allowing the robot arm 200 to directly place the PCB board 500 obliquely and parallel to one side of the first inclined surface 321.

[0030] Maintaining the same feeding height or feeding height includes: for PCB boards 500 that are fed obliquely downwards, each PCB board 500 has a projected height in the moving direction of the lifting device based on the position of its center of gravity or center point, and the downward stroke of the lifting device is determined based on the difference in projected height between them.

[0031] The support platform 320 is movably connected to one side of the fixed plate 110 via a lifting device, so that the support platform 320 can move along the height direction of the fixed plate 110.

[0032] like Figures 3-6As shown, the support platform 320 is specifically composed of a support and a drive plate 340. The drive plate 340 is vertically arranged below one side of the support platform 320. The center of one side of the drive plate 340 is connected to the ball screw 312 of the lifting device through a transmission thread to form a transmission engagement. The top left and right sides of the drive plate 340 are symmetrically provided with horizontally arranged connecting frames 350. The support plate 330 is located on the upper side of the two connecting frames 350, so that the support plate 330 and the drive plate 340 form a vertical drive structure.

[0033] There is a gap between the inner side of the support plate 330 and the top of the drive plate 340. The gap is provided with a first sensor for detecting the feeding of materials. The first sensor is specifically an infrared sensor.

[0034] The support platform 320 has an edge 324 at its bottom. The device has a pressing mechanism 325 on one or both sides near the lifting device. The bottom end of the pressing mechanism 325 is set corresponding to the bottom edge 324 of the storage device to fix the shape of the storage device and avoid the risk of tipping over.

[0035] Multiple limiting protrusions 351 are provided on the two connecting frames 350 facing the outer side of the support plate 330, such as two horizontally distributed limiting protrusions 351. The support plate 330 has corresponding limiting holes 331 that are adapted to the limiting protrusions 351. The limiting protrusions 351 are embedded in the limiting holes 331 to achieve precise positioning of the support plate 330 and the connecting frame 350, preventing the support plate 330 from shifting during the material handling process. To enhance the structural strength between the connecting frame 350 and the drive board 340, two opposing tripods 360 are provided on one side of the drive board 340. One side of the tripod 360 is fixedly connected to the side of the drive board 340 by bolts, and the adjacent side is fixedly connected to the outer wall of the connecting frame 350, forming a stable triangular support structure. The tripod 360 is also provided with multiple circular holes, and the diameter of each circular hole is arranged in an arithmetic progression along the vertical direction. This not only reduces the structural weight, but also serves as temporary mounting holes for the later installation of auxiliary positioning parts for PCB boards 500 of different sizes.

[0036] The lifting device includes a ball screw 312 assembly driven by a servo motor 311. The servo motor 311 is horizontally fixed, and its output shaft is connected to the bottom end of the ball screw 312 via a coupling. The ball screw 312 is connected to a transmission nut 313, which is connected to a drive plate 340 on the support platform 320 to realize the vertical lifting of the support platform 320. The guide mechanism 370 consists of two guide rails 371 parallel to the ball screw 312. The guide rails 371 are vertically fixed, and a sliding member 372 is provided at a corresponding position on the support platform 320. The sliding member 372 has a sliding groove and forms a sliding connection with the guide rails 371.

[0037] This utility model achieves precise height adjustment by driving the support platform 320 through a lifting device. The support platform 320 can be adjusted in real time according to the thickness difference of PCB boards of different specifications, the fluctuation of the unloading position in the production process, and other scenario requirements. Furthermore, the support platform 320 forms an upward-angled unloading space through the first inclined surface 321 and the second inclined surface 322. When storing PCB boards with protruding components such as capacitors, resistors, and lenses on the surface, the hardware side edge of the PCB board can be precisely matched to the angle between the two inclined surfaces. In this invention, the angled structure provides bidirectional limiting support for the edges of the PCB board. Compared to the planar contact of a horizontal platform, the oblique fit increases the contact area between the PCB board and the support platform 320, improving the placement stability of each PCB board. Simultaneously, during multi-layer stacking, the edges of each PCB board are positioned via the angled portion, preventing stacking tilt and wobbling caused by differences in the height of protruding components. This ensures the stability of the overall stacking structure, reduces product loss due to improper storage, and improves production yield. Example 2

[0038] Based on the material unloading and storage device 300 of Embodiment 1, this utility model also includes a logistics trolley, which includes at least one material unloading and storage device 300, and the trolley is movably or detachably connected to one side of the robotic arm 200. This utility model also provides a first method for placing PCB board material 500: The conveying device delivers the PCB board 500 (hereinafter referred to as the board) to one side of the robot arm 200. The robot arm 200 transfers the board to the support platform 320. At this time, the bottom surface of the board is parallel to the first inclined surface 321, and one side abuts against the second inclined surface 322. Materials are stacked obliquely upward along the second inclined surface 322. After each material is placed, the board has a relative displacement in the vertical direction or in the height direction of the fixed plate 110. The lifting device then moves down by one of the relative displacements until the bottom end of the board on the upper side abuts against one side of the groove 323. Example 3

[0039] Based on the material feeding and storage device 300 of Embodiment 1, this utility model provides a second method for placing PCB board 500: The material unloading and storage device 300 is detachably or fixedly mounted on one side of the robot arm 200 via the fixing plate 110; The conveying device delivers the PCB board 500 (hereinafter referred to as the board) to one side of the robot arm 200, and the robot arm 200 transfers the board to the support table 320; At this time, the bottom surface of the board is perpendicular to the first inclined surface 321 and one side is in contact with the second inclined surface 322. The material is placed along the length of the first inclined surface 321 or the second inclined surface 322. The lifting mechanism 310 is not in operation. The second placement method is achieved by the movement of the robot arm 200, so that there is no mutual pressure between each PCB board 500 and the stacking stability is achieved.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
