Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a robotic arm feeding device for anchor bolt pallet production. Background Technology

[0002] Rock bolt trays are typically used in conjunction with rock bolts to support underground rock roadways in coal mines. Existing rock bolt trays are all single-layer structures. During specific support operations, the threaded end of the rock bolt needs to pass through the central hole of the rock bolt tray so that the horizontal side of the rock bolt tray supports the inner wall of the roadway, while the unthreaded end of the rock bolt is suspended.

[0003] The production of anchor bolt trays involves multiple steps, including shearing and stamping. Shearing is used to cut blanks to the required dimensions, while stamping is used to shape the sheared blanks. After stamping, the formed anchor bolt trays need to be removed for subsequent processes. However, removing the stamped anchor bolt blanks carries a certain degree of risk. Therefore, robotic arms are commonly used for this operation. However, existing robotic arms sometimes experience unstable clamping during the clamping process, causing materials to fall off. To address this, this application proposes a robotic arm feeding device for anchor bolt tray production to ensure stable material transfer. Utility Model Content

[0004] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a robotic arm feeding device for anchor bolt tray production. The solution includes a robotic arm body, characterized in that an upper mounting plate is fixedly connected to the working end of the robotic arm body, and a lower mounting plate is correspondingly arranged below the upper mounting plate. Four connecting rods arranged in a rectangular array are fixedly connected to the opposite ends of the upper and lower mounting plates. Four mounting holes are provided on the lower mounting plate, intersecting with the connecting rods. Each mounting hole contains a coaxially slidably connected elastic connecting pipe. An adsorption cover is integrally arranged at the lower end of each elastic connecting pipe. A vacuum pump is arranged at the lower end of the upper mounting plate. The suction end of the vacuum pump is fixedly connected to a five-way connector. The five-way connector includes one main interface and four secondary interfaces. The main interface is fixedly connected to the suction end of the vacuum pump. Each secondary interface is fixedly connected to one end of an elbow, and the other end of each elbow corresponds to and is fixedly connected to the upper end of the elastic connecting pipe.

[0005] Preferably, each of the elastic connecting pipes includes a vertical pipe that is slidably connected to the mounting hole and integrally arranged with the adsorption cover. The upper end of the vertical pipe is fixedly connected to the elbow on its corresponding side. An upper baffle is coaxially fixedly connected to the upper part of the vertical pipe. An upper support spring is coaxially fitted on the vertical pipe. The upper and lower ends of the upper support spring are respectively fixedly connected to the upper baffle and the lower mounting plate. A lower baffle is coaxially fixedly connected to the lower part of the vertical pipe. A lower support spring is coaxially fitted on the vertical pipe. The upper and lower ends of the lower support spring are respectively fixedly connected to the lower mounting plate and the lower baffle.

[0006] Preferably, a soft rubber liner is fixedly connected to the inner edge of the adsorption cover.

[0007] The beneficial effects of this utility model are:

[0008] In use, the robotic arm can move flexibly to transfer materials. When transferring materials, the robotic arm is first driven to make the suction covers at the lower ends of the four elastic connecting pipes abut against the upper surface of the anchor tray. To ensure the sealing of the abutment, a soft inner liner is fixedly connected to the inner edge of the suction cover. This allows the inner liner to fit tightly against the upper surface of the anchor tray under the further downward pressure of the robotic arm, ensuring a tight seal. A vacuum pump can then be used to create a vacuum, allowing the suction cover to hold the anchor tray for transfer. There are four suction covers, each equipped with an inner liner, ensuring a tight suction and stable transfer of the anchor tray, preventing materials from falling off. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: During use, the robotic arm body 1 can move flexibly to facilitate material transfer. When transferring materials, the robotic arm is first driven to make the suction covers 7 at the lower ends of the four elastic connecting pipes 6 abut against the upper surface of the anchor tray 19. To ensure the sealing of the abutment area, a soft inner liner 18 is fixedly connected to the inner edge of the suction cover 7. This allows the inner liner 18 to tightly abut against the upper surface of the anchor tray 19 under the further downward pressure of the robotic arm, ensuring a tight seal. A vacuum pump 8 can then be used to create a vacuum, allowing the suction covers 7 to adhere to the anchor tray 19 for transfer. There are four suction covers 7, each equipped with an inner liner 18, ensuring a tight suction and guaranteeing stable transfer of the anchor tray 19, preventing material from falling off. The robotic arm body is existing technology; its specific structure and operating logic can be achieved using suitable existing technology, and will not be described in detail here.

[0017] In Example 2, based on Example 1, when the anchor rod tray 19 is stamped and needs to be transferred, the robotic arm body 1 is controlled to move so that the four adsorption hoods 7 abut against the upper surface of the anchor rod tray 19 located at the stamping station. In order to ensure the tightness of the abutment between the adsorption hoods 7 and the upper surface of the anchor rod tray 19, and thus to complete the adsorption transfer under the action of the vacuum pump, an inner liner 18 is arranged on the inner edge of the adsorption hoods 7.

[0018] Specifically, after the adsorption cover 7 abuts against the upper surface of the anchor tray 19, in order to ensure the tightness of the contact area and thus complete the vacuuming, the upper mounting plate 2 needs to be further pressed down by the robotic arm body 1. Consequently, the lower mounting plate 3 connected to the connecting rod 4 will also be pressed down, and the elastic connecting pipe 6 connected to the lower mounting plate 3 through the mounting hole 5 will also be subjected to downward pressure. Under the downward pressure, the mounting hole 5 of the mounting plate 3 will slide relative to the vertical pipe 13, thereby stretching the upper support spring 15 fixedly connected between the upper baffle 14 and the lower mounting plate 3, while compressing the lower support spring 17 fixedly connected between the lower baffle 16 and the lower mounting plate 3. Furthermore, the adsorption cover 7, under the downward pressure, will further compress the anchor tray 19, thereby causing the inner liner 18 to undergo a certain deformation to ensure that it can tightly abut against the upper surface of the anchor tray 19, that is, the adsorption cover 7 tightly abuts against the upper surface of the anchor tray 19.

[0019] In Example 3, based on Example 2, the suction end of the vacuum pump 8 is connected to the main interface 10 of the five-way connector 9, and each of the secondary interfaces 11 is fixedly connected to the vertical pipe 13 via elbows 12. After the adsorption hood 7 is tightly pressed against the upper end of the anchor bolt tray 19 by the inner liner 18, the vacuum pump 8 is started to create a vacuum. Under the suction action of the vacuum pump 8, the adsorption hood 7 is vacuumed through the five-way connector 9, elbows 12, and vertical pipe 13, thus allowing the adsorption hood 7, or more precisely, the inner liner 18, to adsorb the anchor bolt tray 19. Then, the robotic arm body 1 can be driven to transfer the material.
