Description

Technical Field

[0001] The utility model belongs to the technical field of material handling, in particular to a sheet material taking device. Background Art

[0002] Automated production equipment often uses suction cups to pick up sheet materials. For example, during the production of printed circuit boards (PCBs), suction cups are required to pick up PCBs for transfer. Currently, common suction cups have a fixed suction area and can only handle the same type of sheet material. This limited functionality means that when producing different product models, the entire suction cup structure must be replaced after downtime, impacting production efficiency and increasing costs.

[0003] The adsorption structure disclosed in the existing patent CN220975785U, "A lateral material removal mechanism for an LDI exposure machine," came into being and can be adapted to different models of products. Currently, there are more and more functional requirements for PCB boards, so more and more electrical components need to be integrated on the PCB boards, which in turn gradually increases the thickness and weight of the PCB boards. On this basis, the existing technologies including this patent often cause products to fall during actual use. The reason is that there are multiple unavoidable through-holes on the PCB board. During the adsorption process, some of the suction cups are located at the through-holes on the product, causing some of the suction cups to fail to adsorb normally, thereby reducing the overall suction force and causing the PCB board to fall and be damaged.

[0004] In order to solve the above problems, designing a sheet material taking device that can adapt to multiple models and ensure adsorption stability is an important technical problem that those skilled in the art need to solve. Utility Model Content

[0005] The purpose of the present invention is to solve the above problems in the prior art and to provide a sheet material taking device.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] The sheet material picking device includes a frame, on which a first adsorption component, a second adsorption component, a first bracket and a second bracket are provided; the first adsorption component is located on the inner side of the second adsorption component; the product is adsorbed by the first adsorption component, and the outer edge of the product is lifted by the first bracket; the upper surface of the material tray is adsorbed by the second adsorption component, and the outer edge of the material tray is lifted by the second bracket.

[0008] Preferably, the first adsorption component includes a group of bionic tentacles arranged on the main part of the frame, and the bionic tentacles rise and fall relative to the frame; each bionic tentacle corresponds to an air source, and the output end of each bionic tentacle is formed with a group of vacuum adsorption holes evenly distributed.

[0009] Preferably, the second adsorption assembly includes a group of suction cups arranged at the edge of the frame; the aperture of the vacuum adsorption hole on the suction cup is larger than the aperture of a single vacuum adsorption hole on the bionic tentacle; the suction cup and the bionic tentacle rise and fall synchronously with the frame.

[0010] Preferably, the first bracket is arranged at both ends of the first crossbeam of the frame; the first bracket includes two symmetrically arranged horizontal moving mechanisms, a vertical moving mechanism and a support plate; the horizontal moving mechanism is connected to the vertical moving mechanism through a mounting frame; the support plate is provided at the bottom end of the vertical moving mechanism; the two horizontal moving mechanisms synchronously drive the vertical moving mechanism to move along the setting direction of the first crossbeam to adjust the distance between the relatively arranged support plates.

[0011] Preferably, the vertical moving mechanism 1 includes a first cylinder arranged on the upper surface of the horizontal moving mechanism 1 and a second cylinder arranged at the bottom end of the mounting frame; the first cylinder drives the mounting frame to move up and down, and preliminarily adjusts the height of the pallet 1; the second cylinder drives the pallet 1 to move up and down, and accurately adjusts the position of the pallet 1.

[0012] Preferably, all the second cylinders are symmetrically distributed in a rectangular shape, and each of the second cylinders corresponds to one of the support plates.

[0013] Preferably, the second bracket is arranged at both ends of the second crossbeam of the frame; the second bracket includes two symmetrically arranged horizontal moving mechanisms 2, a vertical moving mechanism 2 and a pallet 2; the horizontal moving mechanism 2 is connected to the vertical moving mechanism 2 through a mounting plate; the pallet 2 is provided at the bottom end of the vertical moving mechanism 2; the two horizontal moving mechanisms 2 synchronously drive the vertical moving mechanism 2 to move along the setting direction of the second crossbeam to adjust the distance between the two relatively set pallets 2.

[0016] Preferably, the frame is rectangular; a group of suction cups located on each side of the rectangle are supplied with air by an air source.

[0017] The advantages of the technical solution of this utility model are mainly reflected in:

[0018] The first adsorption component is matched with the first bracket. The first adsorption component adsorbs the upper surface of the product. After the product moves upward, it is clamped and supported by the first bracket to ensure the stability of the product loading and unloading process, thereby ensuring the product yield rate;

[0019] The bionic tentacle contacts the product and generates suction. Since the vacuum adsorption holes on the output end of the bionic tentacle are small in diameter and high in density, even if some of the vacuum adsorption holes are located in the through-holes of the PCB board, it does not affect the overall adsorption of the bionic tentacle to the PCB board. Therefore, the adsorption effect is better under the same suction force, ensuring that the bionic tentacle can effectively adsorb the product during the adsorption process.

[0020] The second adsorption component is matched with the second bracket. The side wall of the material tray is clamped and supported by the second bracket while taking the material. The second adsorption component then adsorbs the upper surface of the material tray to ensure the stability of the material tray and the product during the loading and unloading process, thereby ensuring the product yield.

[0028] like Figure 1 As shown, the present invention discloses a sheet material retrieving device, including a frame 5. In the present invention, the frame 5 is preferably rectangular. Of course, in other embodiments, the frame 5 can also be designed into other shapes such as a circle. The specific shape can be adjusted according to the shape of the product and the material tray carrying the product, and is not limited here. The top of the frame 5 is provided with a lifting mechanism. The lifting structure can be a structure such as an electric cylinder, a lead screw, or a linear module disclosed in the prior art, and is not limited here.

[0029] Combine Figure 2 and Figure 4 As shown, the frame 5 is provided with a first adsorption component 1. Specifically, the first adsorption component 1 includes a group of bionic tentacles 11 provided on the main part of the frame 5. Each of the bionic tentacle 11 corresponds to an air source, and the output end of each of the bionic tentacle 11 is formed with a group of vacuum adsorption holes evenly distributed. When adsorbing a product, the bionic tentacle 11 rises and falls relative to the frame 5. The bionic tentacle contacts the product and generates suction. Since the vacuum adsorption holes on the output end of the bionic tentacle are small in diameter and high in density, even if the local vacuum adsorption holes are located in the through-holes of the PCB board, it does not affect the adsorption of the bionic tentacle on the PCB board as a whole. Therefore, the adsorption effect is better under the same suction force, ensuring that the bionic tentacle can effectively adsorb the product during the adsorption process.

[0030] The frame 5 is provided with a first bracket 3, which is provided at both ends of the first crossbeam 51 of the frame 5. Figure 1 and Figure 5As shown, the first bracket 3 comprises two symmetrically arranged horizontal moving mechanisms 31, a vertical moving mechanism 32, and a support plate 33. The horizontal moving mechanism 31 is connected to the vertical moving mechanism 32 via a mounting bracket; the support plate 33 is mounted at the bottom end of the vertical moving mechanism 32. The two horizontal moving mechanisms 31 synchronously drive the vertical moving mechanism 32 to move along the direction of the first crossbeam 51 to adjust the spacing between the opposing support plates 33.

[0031] Further, such as Figure 5 As shown, the vertical moving mechanism 1 32 includes a first cylinder 321 provided on the upper surface of the horizontal moving mechanism 1 31 and a second cylinder 322 provided at the bottom end of the mounting frame. The first cylinder 321 drives the mounting frame to move up and down, preliminarily adjusting the height of the pallet 1 33; the second cylinder 322 drives the pallet 1 33 to move up and down, accurately adjusting the position of the pallet 1 33. All the second cylinders 322 are symmetrically distributed in a rectangular shape, and each second cylinder 322 corresponds to one pallet 1 33. The lifting height of the pallet 1 is controlled step by step by the first cylinder and the second cylinder, so that products of different thicknesses can be carried; the pallet 1 is then driven by the horizontal moving mechanism 1 to clamp the edge of the product; that is, the product is adsorbed by the first adsorption component 1, and when the product is separated from the tray, the first bracket 3 is started, and the outer edge of the product is lifted by the first bracket 3. The first adsorption component is matched with the first bracket, and the first adsorption component adsorbs the upper surface of the product. After the product moves upward, it is clamped and supported by the first bracket to ensure the stability of the product loading and unloading process, thereby ensuring the product yield.

[0032] like Figures 1 to 3 As shown, the frame 5 is further provided with a second adsorption assembly 2, and the first adsorption assembly 1 is located inside the second adsorption assembly 2. The upper surface of the tray is adsorbed by the second adsorption assembly 2, and the outer edge of the tray is supported by the second bracket 4.

[0033] Furthermore, the second adsorption assembly 2 includes a set of suction cups 21 arranged at the edge of the frame 5. When the frame 5 is rectangular, the set of suction cups 21 located on each side of the rectangular frame 5 is supplied with air by an air source. Since through holes are generally not formed on the material tray, the suction cups 21 in the present invention are known ordinary suction cups, and their structure is not described in detail here. Furthermore, the aperture of the vacuum adsorption hole on the suction cup 21 is larger than the aperture of the single vacuum adsorption hole on the bionic tentacle 11; and the suction cup 21 and the bionic tentacle 11 rise and fall synchronously with the frame 5.

[0034] like Figure 1 and Figure 3As shown, the frame 5 is provided with the second bracket 4; the second bracket 4 is provided at both ends of the second beam 52 of the frame 5. The second bracket 4 includes two symmetrically arranged horizontal moving mechanisms 2 41, a vertical moving mechanism 2 42 and a pallet 2 43. The horizontal moving mechanism 2 41 is connected to the vertical moving mechanism 2 42 through a mounting plate. The pallet 2 43 is provided at the bottom end of the vertical moving mechanism 2 42; the two horizontal moving mechanisms 2 41 synchronously drive the vertical moving mechanism 2 42 to move along the setting direction of the second beam 52 to adjust the distance between the two relatively arranged pallets 2 43. The second adsorption component is matched with the second bracket, and the side wall of the material tray is clamped and supported by the second bracket while taking the material, and then the upper surface of the material tray is adsorbed by the second adsorption component to ensure the stability of the material tray and the product during the loading and unloading process, thereby ensuring the product yield.

[0035] Further, such as Figure 2 As shown, the first crossbeam 51 and the second crossbeam 52 are arranged at an angle, and in the present invention, the two are preferably arranged vertically. Figure 1 or Figure 3 As shown, in the present invention, the horizontal moving mechanism 1 31 and the horizontal moving mechanism 2 41 are designed as slide cylinders, and the vertical moving mechanism 2 42 is a driving cylinder. Figure 3 and Figure 5 As shown, the pallet 1 33 and the pallet 2 43 are L-shaped plates, and the lowest end of the pallet 1 33 is preferably not lower than the lowest end of the pallet 2 43 .

[0036] There are many implementation methods for the present utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the present utility model.
