Description

Technical Field

[0001] The utility model relates to the technical field of stacking equipment, in particular to an automatic lever material blocking device. Background Art

[0002] In the stamping automation line, there are two ways of stacking, manual stacking and robot stacking.

The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0053] The terms "a", "an", "the", "" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0054] like Figure 1-5 As shown, an automatic lever material blocking device of an embodiment of the utility model comprises a material frame 1, a baffle component 2 and a lever component 3, wherein the baffle component 2 is rotatably connected to the inside of the material frame 1, one end of the lever component 3 is connected to the robot 4, and the other end of the lever component 3 is used to move the baffle component 2, and the baffle component 2 has a first position and a second position, wherein the lever component 3 can drive the baffle component 2 to switch between the first position and the second position.

[0055] Figure 2The state of the baffle member 2 in the first position is shown. At this time, the state of the baffle member 2 before loading is also the initial state of the baffle member 2. In this state, the sheet materials such as the hanging parts can be easily loaded into the material frame 1, and the baffle member 2 can be prevented from protruding from the material frame 1 to affect the loading; Figure 1 The second position of the baffle component 2 is shown to be the state of the baffle component 2 after loading is completed. At this time, the baffle component 2 is needed to block the material to prevent the material frame 1 from shaking, falling, scratching, etc. during transportation. The present application can drive the baffle component 2 to automatically block the material through the robot 4 and the lever component 3. The baffle component 2 can be quickly pulled down by the robot, which improves the work efficiency. After field testing, the robot can ensure that the automatic lever can be completed within 10 seconds. The present application can avoid the safety risks caused by human participation and improve the work stacking efficiency.

[0056] like Figure 1-3 In a preferred embodiment of the material frame 1 shown, the material frame 1 includes a base plate 11 and two column groups 12. The two column groups 12 are symmetrically distributed and vertically connected to the base plate 11. Each column group 12 is connected to a baffle component 2. Through the cooperation of the two baffle components 2, the problems of sheet material shaking, falling, and scratching caused by sheet material transportation can be effectively prevented, thereby improving the safety performance of the material frame 1.

[0057] like Figure 1-4 In a preferred embodiment of the baffle member 2 shown, the baffle member 2 includes a rotating shaft 21, a first baffle 22, and a driving assembly 23. The rotating shaft 21 is rotatably connected to the column group 12, one end of the first baffle 22 is fixed to one side of the rotating shaft 21 close to the feeding end of the material frame 1, and the other end of the first baffle 22 is used to block the material; the driving assembly 23 is detachably connected to the connection between the rotating shaft 21 and the first baffle 22, and the driving assembly 23 and the first baffle 22 are respectively located on both sides of the rotating shaft 21; wherein the driving assembly 23 can drive the rotating shaft 21 and the first baffle 22 to rotate from the first position to the second position. In this embodiment, Figure 2 In the first position shown, the first baffle 22 is parallel to the column 121, and the interference of the first baffle 22 with the loading can be avoided. Figure 1 In the second position shown, the first baffle 22 and the column 121 are in a vertical state. At this time, the first baffle 22 can prevent the sheet material from tilting and falling when the forklift transports the material frame 1. Therefore, in this embodiment, the robot 4 is used to realize automatic lever shifting, which avoids the time waste and safety risks caused by the participation of personnel in lever shifting, improves work efficiency, facilitates installation and disassembly, and has strong maintainability.

[0058] In addition, the column group 12 is provided with a rotating shaft bracket 13 for installing the rotating shaft 21. The rotating shaft 21 is rotatably connected between the rotating shaft brackets 13, which can reduce the resistance of the robot 4 when shifting the rod. The robot 4 only needs to gently shift the first baffle 22, and the rotating shaft 21 can drive the first baffle 22 to rotate.

[0059] like Figure 1-4 In a preferred embodiment of the driving assembly 23 shown, the driving assembly 23 includes a mounting plate 231, a clamping assembly 232, a dial plate 233 and a limit block 234. One end of the clamping assembly 232 is detachably connected to the rotating shaft 21, and the other end is connected to the mounting plate 231. The dial plate 233 is hinged to the end of the mounting plate 231 away from the rotating shaft 21. One end of the limit block 234 is connected to the end of the dial plate 233 close to the rotating shaft 21, and the other end of the limit block 234 extends toward the direction of the clamping assembly 232 to limit the rotation range of the dial plate 233. Of course, the limit block 234 can also be fixed to the clamping assembly 232 at one end and extend to one end of the dial plate 233 at the other end to limit the rotation range of the dial plate 233.

[0060] In this embodiment, the clamping assembly 232 is detachably connected to the rotating shaft 21, and the rotating shaft 21 is rotatably connected between the two columns 121. Since the dial plate 233 and the mounting plate 231 are hinged, when the first baffle 22 is in the first position, the mounting plate 231 and the dial plate 233 are coplanar; when the first baffle 22 is in the second position, the mounting plate 231 and the dial plate 233 are vertical. If the robot 4 uses the lever component 3 to shift the first baffle 22 at this time, at the moment when the first baffle 22 rotates upward, the dial plate 233 moves downward under the influence of its own gravity, thereby driving the rotating shaft 21 and the first baffle 22 to rotate outward through the mounting plate 231 and the clamping assembly 232, so that the first baffle 22 switches to the first position, thereby completing the automatic lever shifting process of the first baffle 22. In this embodiment, the first baffle 22 is quickly pulled down by the robot 4. After field testing, the robot 4 can ensure that the automatic lever can be completed within 10 seconds. That is, the present application utilizes the hinged structure of the lever 233 and the mounting plate 231 and the deadweight of the lever 233 to complete the automatic and rapid lever pull of the first baffle 22. It avoids the safety risks caused by human participation, is simple to operate, and improves work efficiency. The modification structure of the drive assembly 23 and the material frame 1 is simple, and each material frame 1 modification only takes 5 minutes to complete, and the production cost is low.

[0061] like Figure 1-4In a preferred embodiment of the clamping assembly 232 shown, the clamping assembly 232 includes two symmetrically arranged clamps 2321 and bolts 2322, one end of the clamp 2321 is connected to the rotating shaft 21, and the other end is connected to the mounting plate 231, and the bolt 2322 is connected to one of the clamps 2321 for fixing the clamp 2321 and the rotating shaft 21. The bolt 2322 enables the installation and adjustment of the clamping assembly 232 in different directions, improves the compatibility of the equipment, and facilitates maintenance and replacement.

[0062] like Figure 1-4 In a preferred embodiment of the clamping assembly 232 shown, the two clamps 2321 each include an arc plate 23211 and a connecting plate 23212 for connecting the rotating shaft 21, the connecting plate 23212 is connected to the side of the arc plate 23211 close to the mounting plate 231, and is detachably connected to the mounting plate 231, wherein the two arc plates 23211 are arranged to form a mounting groove, the rotating shaft 21 is inserted into the mounting groove, and then the rotating shaft 21 and the clamps 2321 are fixed by bolts 2322. The two clamps 2321 can be installed on different rotating shafts 21, with a wide range of adaptability, and if one of them fails, the part can be directly replaced, which is convenient for maintenance.

[0063] like Figure 1-4 In a preferred embodiment shown, each column group 12 includes two columns 121 and a cross bar 122 connected between the two columns 121, the rotation shaft 21 is located on the inner side of the cross bar 122, the first baffle 22 can abut against the cross bar 122 after rotating with the rotation shaft 21, and the cross bar 122 is used to limit the rotation range of the first baffle 22. When the first baffle 22 rotates to the first position, the first baffle 22 can abut against the cross bar 122, and the cross bar 122 is used to limit the rotation range of the first baffle 22, so that the first baffle 22 switches between the first position and the second position.

[0064] like Figure 1-4 In a preferred embodiment of the baffle member 2 shown in FIG. 1 , the baffle member 2 further comprises a second baffle 24, the second baffle 24 is located inside the material frame 1, and the second baffle 24 is fixed to the side of the rotating shaft 21 away from the feeding end of the material frame 1, and the second baffle 24 and the first baffle 22 are arranged vertically. The purpose of this design is that when the first baffle 22 is in the first position such as Figure 1 When the first baffle 22 is vertical to the column 121, the sheet material can be prevented from shaking, falling or being scratched during the loading process without interfering with the loading.

[0065] In addition, the second baffle 24 can also be arranged in parallel with the first baffle 22, so that during transportation, the second baffle 24 and the first baffle 22 simultaneously block the material to prevent the sheet material from tilting.

[0066] like Figure 1 and 5In a preferred embodiment of the lever component 3 shown, the lever component 3 includes a lever assembly 31, and the lever assembly 31 includes a U-shaped bracket 311 and two levers 312, and the two levers 312 are symmetrically distributed at both ends of the U-shaped bracket 311, wherein the two levers 312 can be inserted into the material frame 1 and drive the first baffle 22 to move under the drive of the robot 4. Specifically, when the lever assembly 31 is inserted into the material frame 1, the two levers 312 are parallel to the bottom plate 11 and perpendicular to the rotating shaft 21, and the distance between the free ends of the two levers 312 is less than the distance between the two rotating shafts 21, and the robot 4 only needs to translate the machinery to complete the shifting of the two first baffles 22. When the first baffle 22 is in the second position, the two toggle rods 312 can push the first baffle 22 upward under the drive of the robot 4, so that the first baffle 22 rotates to the first position, which is convenient for loading and unloading sheet materials; when the first baffle 22 is in the first position, the two toggle rods 312 can quickly push the first baffle 22 down under the drive of the robot 4, so that the first baffle 22 moves to the second position to block the material.

[0067] The U-shaped bracket 311 includes two round rods 3111 and a connecting rod 3112 connected between the two round rods 3111. By selecting different connecting rods 3112, the relative distance between the two round rods 3111 can be changed, thereby adjusting the operating range of the two toggle rods 312 to adapt to different types of material frames 1. Different toggle rod components 3 can be selected according to different material frames 1, thereby improving the compatibility of the equipment and the application range of the product.

[0068] like Figure 1 and 5 In a preferred embodiment of the lever member 3 shown, the lever member 3 further includes a mounting frame 32 and an end picker 33. The end picker 33 and the lever assembly 31 are detachably connected to the two ends of the mounting frame 32, respectively. The mounting frame 32 is provided with a connection portion for connecting with the robot 4. The two round rods 3111 are detachably connected to one end of the mounting frame 32 through a quick connector. In addition, in some embodiments, as long as the two ends of the end picker 33 can move the first baffle 22, the end picker 33 can also be provided at both ends of the mounting frame 32, as long as the lever shifting process can be realized, and the present application does not make any limitation here.

[0069] The specific principles are as follows:

[0070] The stacking process at the end of the original stamping automation line is as follows: after stamping is completed, the sheet material in the mold cavity is grabbed by the robot and placed on the belt conveyor. The belt conveyor transports the sheet material to the outside of the closed line, and the operator completes quality inspection, stacking, lever shifting and other tasks.

[0071] Application example of this technology: After the stamping is completed, the sheet material in the mold cavity is grabbed by the manipulator and placed on the belt conveyor. The belt conveyor conveys the sheet material to the outside of the closed line, and the operator or online equipment completes the quality inspection. Then the manipulator puts the sheet material into the material frame 1, and the robot 4 uses the toggle rod 312 to toggle the first baffle 22 to the second position, so that the first baffle 22 can block the material; then during the unloading process, the robot 4 can use the toggle rod 312 to hit the first baffle 22 upwards, and the robot 4 only needs to move horizontally 20mm to complete the toggle process of the two first baffles 22. The self-weight of the toggle plate 233 quickly rotates vertically downward, and the first baffle 22 is driven by the toggle plate 233 to quickly rotate to the first position, automatically realizing fast and efficient lever shifting. This application can achieve the completion of lever shifting within 110 seconds for each material frame, avoiding the time waste and safety risks caused by the participation of personnel in lever shifting. No personnel are required before the forklift transfers the material frame 1. At the same time, the second baffle 24 behind the material frame 1 can be welded and fixed to avoid the first baffle 22 not being in place, causing the sheet material to shake, fall, or be scratched due to the transfer of the sheet material, thereby effectively improving safety and stacking efficiency.
