Description

Technical Field

[0001] This application relates to the field of automated machining technology, and in particular to a steel plate loading device. Background Technology

[0002] During container manufacturing, after the steel sheets are cut to specific dimensions, sandblasting is required to enhance paint adhesion. This sandblasting process involves placing the steel sheets individually onto a machine tool's worktable. Currently, a robotic arm is typically used to lift the steel sheets onto the worktable. The robotic arm picks up a sheet, moves it above the worktable, places it on the worktable, and then moves back to pick up another sheet, repeating this process.

[0003] For the aforementioned technologies, the process of the robotic arm repeatedly grabbing steel plates and moving back and forth on the machine tool table takes a certain amount of time, and the efficiency of steel plate loading needs to be improved. Utility Model Content

[0004] To improve the efficiency of steel plate feeding, this application provides a steel plate feeding device.

[0005] The steel plate loading device provided in this application adopts the following technical solution: A steel plate loading device includes a frame, a horizontally arranged conveying mechanism mounted on the frame, and a lifting mechanism mounted on the frame for lifting steel plates onto the conveying mechanism. The conveying mechanism includes a drive roller rotatably mounted on the frame, a driven roller rotatably mounted on the frame, a conveyor belt mounted on the drive roller and the driven roller, and a drive motor for driving the drive roller to rotate. The lifting mechanism includes a lifting suction cup for attracting steel plates and a lifting drive component mounted on the frame for driving the lifting suction cup to move up and down. The frame has a magnetic support arranged on the upper side of the lower section of the conveyor belt.

[0006] By adopting the above technical solution, when steel plates are placed under the frame, the lifting suction cups, driven by the lifting drive, can sequentially lift the steel plates below. Due to the magnetic support, the steel plates are adsorbed onto the lower surface of the lower section of the conveyor belt. The conveying mechanism moves the steel plates from one side to the other, and after detaching from the other side, they fall onto the sandblasting feed conveyor table. Compared to traditional robotic arms, this steel plate loading device has a higher loading efficiency.

[0007] Optionally, the magnetic support includes a fixed guide rail arranged along the conveying direction and a plurality of fixed magnetic blocks for attracting the steel plate; the plurality of fixed magnetic blocks are arranged at intervals along the length direction on the bottom surface of the fixed guide rail, and the distance between adjacent fixed magnetic blocks is no more than 20cm.

[0008] By adopting the above technical solution, the specific structure of the magnetic support is disclosed, which enables the steel plate to be stably adsorbed on the lower side of the magnetic support, i.e., the lower surface of the lower end of the conveyor belt.

[0009] Optionally, the bottom surface of the fixed guide rail is provided with an arrangement groove for arranging the fixed magnetic block, and the depth of the arrangement groove is not greater than the thickness of the fixed magnetic block.

[0010] By adopting the above technical solution, the installation method of the fixed magnetic block and the fixed guide rail is disclosed. By installing the fixed magnetic block in the arrangement groove on the lower side of the fixed guide rail, the connection strength between the fixed magnetic block and the fixed guide rail is relatively ideal.

[0011] Optionally, both sides of the fixed guide rail are provided with roller assemblies that support the upper surface of the lower section of the conveyor belt. The roller assembly includes a plurality of support rollers arranged along the length direction of the fixed guide rail, and the bottom end of the support roller is not higher than the bottom surface of the fixed magnetic block.

[0012] By adopting the above technical solution, the roller assembly can be supported on both sides of the conveyor belt, so that the conveyor belt will not directly rub against the lower surface of the fixed guide rail, which helps to reduce the probability of damage to the upper side of the conveyor belt due to friction and extend its service life.

[0013] Optionally, the support roller includes a rotatably arranged support bearing and a fixing bolt that presses the inner ring of the support bearing against the outer side of the fixed guide rail.

[0014] By adopting the above technical solution, it is easy to support the rollers to be installed on the fixed guide rail, and the support effect is quite ideal.

[0015] Optionally, the distance between adjacent support rollers is no more than 5cm.

[0016] By adopting the above technical solution, the spacing between adjacent support rollers is limited, which helps to ensure the support effect of the support rollers on the edge of the conveyor belt.

[0017] Optionally, it includes two conveying mechanisms arranged symmetrically on the left and right sides; the magnetic supports in the frame are arranged in a one-to-one correspondence with the conveying mechanisms.

[0018] By adopting the above technical solution, setting up two conveying mechanisms can better support and convey the steel plate, which helps to improve the conveying effect of the steel plate.

[0019] Optionally, a conveying platform for conveying steel plates to the lower side of the lifting mechanism may also be included.

[0020] By adopting the above technical solution, the setting of the conveyor table allows the workers to place the steel plate on one side of the conveyor table, that is, the outside of the frame. After being conveyed by the conveyor table, the steel plate can be transported to the lower side of the lifting mechanism, which makes it easier to place the steel plate under the lifting mechanism.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The lifting mechanism uses a lifting drive to lift the steel plates sequentially using suction cups. Magnetic supports then adhere the steel plates to the lower surface of the conveyor belt, and the conveying mechanism laterally moves the steel plates to the sandblasting feed conveyor table. Compared to traditional robotic arms, this device significantly improves feeding efficiency. 2. Multiple fixed magnetic blocks arranged on the bottom surface of the fixed guide rail can ensure that the steel plate is firmly adsorbed on the surface of the guide rail. At the same time, the roller assembly installed on both sides of the guide rail can effectively reduce the friction between the upper side of the conveyor belt and the bottom surface of the fixed magnetic blocks, reduce the probability of the upper side of the conveyor belt being damaged due to friction, and extend its service life. 3. Setting up two conveying mechanisms with magnetic supports arranged in a one-to-one correspondence with the conveying mechanisms can further ensure the stability of steel plate conveying.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a steel plate loading device. (Refer to...) Figure 1 The steel plate loading device includes a frame 1, a conveying mechanism 2 mounted on the frame 1 and arranged horizontally, a lifting mechanism 3 mounted on the frame 1 for lifting the steel plate to the conveying mechanism 2, and a conveying table 4 for conveying the steel plate to the lower side of the lifting mechanism 3.

[0029] Reference Figure 1 The conveyor table 4 is a roller conveyor table. The conveyor table 4 is arranged laterally at the bottom of the frame 1, with one end of the conveyor table 4 located on the outside of the frame 1 and the other end located at the bottom of the frame 1. When conveying steel plates, the steel plates can be placed on the conveyor table 4 at the end located on the outside of the frame 1. After being conveyed by the conveyor table 4, the steel plates can be conveyed to the lower side of the lifting mechanism 3.

[0030] Reference Figure 1 and Figure 2 The frame 1 includes a top support 11, a magnetic support 12 located below the top support 11 and arranged horizontally, and a connecting rod 13 connecting the magnetic support 12 and the top support 11. There are two magnetic supports 12, which are arranged symmetrically from left to right.

[0031] Reference Figure 1 and Figure 2 The steel plate loading device has two conveying mechanisms 2, which are arranged in a one-to-one correspondence with the magnetic supports 12. Each conveying mechanism 2 includes a drive roller 21 horizontally rotatably mounted at one end of the corresponding magnetic support 12, a driven roller 22 horizontally rotatably mounted at the other end of the corresponding magnetic support 12, a conveyor belt 24 mounted on the drive roller 21 and the driven roller 22, and a drive motor 23 that drives the drive roller 21 to rotate. The magnetic support 12 is arranged inside the conveyor belt 24 and supported on the upper surface of the lower section of the corresponding conveyor belt 24.

[0032] Reference Figure 2 and Figure 3 The magnetic support 12 includes a fixed guide rail 121 arranged along the conveying direction and a plurality of fixed magnetic blocks 122 for attracting steel plates. The plurality of fixed magnetic blocks 122 are arranged at intervals along the length direction on the bottom surface of the fixed guide rail 121. In this embodiment, the spacing between adjacent fixed magnetic blocks 122 is 10cm. To facilitate the installation of the fixed magnetic blocks 122 on the lower side of the fixed guide rail 121, the bottom surface of the fixed guide rail 121 is provided with an arrangement groove 1211 for arranging the fixed magnetic blocks 122. In order to ensure that the connection strength between the fixed magnetic blocks 122 and the fixed guide rail 121 is relatively ideal, the depth of the arrangement groove 1211 is not greater than the thickness of the fixed magnetic blocks 122, so that the bottom surface of the fixed magnetic blocks 122 can be exposed in the arrangement groove 1211.

[0033] Reference Figure 2 and Figure 4To extend the service life of the conveyor belt 24 and reduce the probability of damage caused by friction between the conveyor belt 24 and the fixed magnetic block 122, roller assemblies supporting the upper surface of the lower section of the conveyor belt 24 are provided on both sides of the fixed guide rail 121. The roller assemblies are supported on both sides of the conveyor belt 24. The roller assembly includes multiple support rollers 1212 arranged along the length of the fixed guide rail 121. The bottom end of the support roller 1212 is not higher than the bottom surface of the fixed magnetic block 122, so that the conveyor belt 24 does not directly rub against the lower surface of the fixed guide rail 121. The support roller 1212 includes a rotatably arranged support bearing 12121 and a fixing bolt 12122 that presses the inner ring of the support bearing 12121 against the outer side of the fixed guide rail 121. The fixed guide rail 121 has a fixing screw hole 1213 that mates with the fixing bolt 12122. To ensure the support effect of the support rollers 1212 on the edge of the conveyor belt 24, the distance between adjacent support rollers 1212 shall not exceed 5cm.

[0034] Reference Figure 2 and Figure 4 The lifting mechanism 3 includes a lifting drive 31 connected to the lower side of the top bracket 11, a lifting bracket 32 ​​installed below the lifting drive 31 and driven to move up and down by the lifting drive 31, and a lifting suction cup 33 installed on the lifting bracket 32. The lifting drive 31 is an inverted lifting cylinder with its piston rod extending vertically downwards; the lifting bracket 32 ​​is a connecting rod arranged in the front-to-back direction and locked to the bottom end of the piston rod of the lifting cylinder by screws; the lifting suction cup 33 is a vacuum suction cup, and in this embodiment, there are six lifting suction cups 33 arranged at intervals in the front-to-back direction.

[0035] Reference Figure 1 and Figure 4 In this embodiment, the steel plate loading device has three sets of lifting mechanisms 3, which are arranged at intervals on the left and right at the bottom of the top frame 1. Among them, two magnetic supports 12 are respectively arranged on the supports of two adjacent lifting mechanisms 3, so that the steel plate can be stably attracted by the magnetic supports 12 after being lifted by the lifting mechanism 3.

[0036] The implementation principle of the steel plate loading device in this application embodiment is as follows: the worker places the stacked steel plates on the conveyor table 4 outside the frame 1, and the conveyor table 4 transports the steel plates to the lower side of the lifting mechanism 3; the lifting mechanism 3 lifts the topmost steel plate so that the steel plate is attached to the lower surface of the conveyor belt 24 and the steel plate is attracted by the magnetic bracket 12; after being transported by the conveyor mechanism 2, the steel plate moves forward until it is detached from the magnetic attraction of the magnetic bracket 12 and falls off the conveyor mechanism 2 and onto the conveyor mechanism 2 of the sandblasting device.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
