Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-5 As shown, a lightweight logistics robot gripping device proposed in one embodiment of the present invention includes a gripping robotic arm structure 1 and a multi-directional gripping structure 2. Both the gripping robotic arm structure 1 and the multi-directional gripping structure 2 are controlled and powered in real time by existing control systems and power supply systems.

[0021] The multi-directional clamping structure 2 includes a connecting top frame 201, the bottom end of which is movably engaged with a drive platform 202, and the top end of the drive platform 202 is equipped with two oppositely arranged first electric push rods 203, the movable ends of which are fixedly mounted with clamping side plates 204.

[0022] A pressure sensor can be installed on the inner side of the clamping side plate 204. The pressure sensor can monitor the clamping force between the clamping side plate 204 and the goods in real time.

[0023] When a logistics robot is handling goods, if the clamping force is too small, it may not be able to hold the goods securely and there is a risk of the goods slipping. In this case, the pressure sensor will quickly feed back the detected signal to the control system.

[0024] After receiving the signal, the control system can immediately adjust the extension and retraction of the first electric push rod 203 to increase the clamping force of the clamping side plate 204 on the goods, ensuring that the goods are firmly clamped.

[0025] When the clamping force is too large and may damage the goods, the pressure sensor will also send a signal to the control system, which will then control the first electric push rod 203 to retract appropriately, reduce the clamping force, and avoid damage to the goods.

[0026] A second electric push rod 210 is hinged to the outer side of the clamping side plate 204. A deflection frame 211 is hinged to the movable end of the second electric push rod 210. A hinge frame 212 is welded to the outer side of the deflection frame 211. A base support frame 216 is fixedly installed at the bottom end of the hinge frame 212. The base support frame 216 extends to the bottom of the clamping side plate 204.

[0027] like Figure 2 As shown, in some embodiments, the gripping robotic arm structure 1 includes a mounting bracket 101, a rotating component 102 is provided at the top of the mounting bracket 101, a movable component 103 is provided at the movable end of the rotating component 102, and a connecting component 104 is provided at the other end of the movable component 103. The other end of the connecting component 104 is movably engaged with the top of the connecting top frame 201.

[0028] Specifically, by using the rotating component 102 in the gripping robotic arm structure 1, the movable component 103 can be rotated, thereby adjusting the position of the multi-directional clamping structure 2 so that it can accurately reach above the goods, facilitating subsequent clamping and bottoming operations of the goods.

[0029] The cooperation between the movable part 103 and the connecting part 104 enables the connecting top frame 201 to be flexibly connected to the gripping robotic arm structure 1, ensuring the stability and coordination of the entire device during the cargo handling process.

[0030] like Figure 3 As shown, in some embodiments, buffer pads 205 are provided at opposite ends of the two clamping side plates 204, and the buffer pads 205 are soft silicone grease pads.

[0031] Specifically, the buffer pad 205 can buffer and protect the goods when the clamping side plate 204 clamps them, avoiding damage to the surface of the goods due to excessive clamping force. This buffer protection is especially important for some goods with fragile or easily damaged surfaces, effectively improving the applicability and safety of the device for different types of goods.

[0032] like Figure 4 As shown, in some embodiments, a movable stage 206 is fixedly installed at the opposite ends of the two clamping side plates 204, a slide rod 207 is fixedly installed at the bottom end of the drive platform 202, a slider 208 is fixedly installed at the top end of the movable stage 206, the inner wall of the slider 208 is slidably connected to the surface of the slide rod 207, and a limit block 209 is fixedly sleeved on the side end of the slide rod 207.

[0033] Specifically, the sliding connection of the slider 208 on the slide rod 207 enables the two clamping side plates 204 to move smoothly and steadily relative to each other under the drive of the first electric push rod 203, ensuring the accuracy and stability of the clamping action.

[0034] The setting of the limiting block 209 restricts the sliding range of the slider 208, preventing the slider 208 from sliding out of the slide bar 207, thereby avoiding excessive movement of the clamping side plate 204 and ensuring the normal operation of the entire multi-directional clamping structure 2. like Figure 5 As shown, in some embodiments, the top end of the hinge frame 212 is rotatably connected to a hinge seat 213, and the side end of the hinge seat 213 is connected to the outer wall of the clamping side plate 204.

[0035] Specifically, the rotatable connection between the hinge seat 213 and the hinge frame 212 allows the hinge frame 212 to rotate flexibly within a certain range. When the second electric push rod 210 pushes the deflection frame 211, the hinge frame 212, and the bottom support frame 216 to move, this rotatable connection method can better adapt to the bottom support requirements of goods of different shapes, allowing the bottom support frame 216 to fit more closely to the bottom of the goods, thus improving the bottom support effect and stability.

[0036] like Figure 5 As shown, in some embodiments, an outer plate 214 is fixedly installed on the outer side of the clamping side plate 204, and a follower frame 215 is rotatably connected to the bent part of the outer plate 214. The bottom end of the follower frame 215 is fixedly connected to the inner side of the support frame 216.

[0037] Specifically, the external plate 214 and the follower frame 215 further enhance the linkage and coordination of the entire multi-directional clamping structure 2. During the movement of the base support frame 216 driven by the second electric push rod 210, the follower frame 215 rotates accordingly at the bend of the external plate 214 as the base support frame 216 moves. This design makes the movement of the base support frame 216 more stable and reliable, better supporting the bottom of the goods and further improving the stability and safety of the device during goods handling.

[0038] When in use, once the goods arrive at the location of the logistics robot, the gripping robotic arm structure 1 begins to work.

[0039] The rotating component 102 rotates and adjusts according to the position of the goods, so that the multi-directional clamping structure 2 is in the appropriate orientation.

[0040] Subsequently, the two first electric push rods 203 on the drive platform 202 are activated simultaneously, causing the two clamping side plates 204 to move relative to each other and gradually approach the side of the cargo.

[0041] After the clamping side plate 204 initially clamps and fixes the side end of the goods, the second electric push rod 210 starts to work. The second electric push rod 210 pushes the deflection frame 211, the deflection frame 211 drives the hinge frame 212 to move, and the hinge frame 212 causes the bottom support frame 216 to rotate until the bottom support frame 216 supports the goods from the bottom.

[0042] In summary, by setting up a multi-directional clamping structure 2, and using two first electric push rods 203 to drive the two clamping side plates 204 to move relative to each other, the side end of the goods can be initially clamped and fixed. At the same time, the second electric push rod 210 pushes the deflection frame 211, the articulation frame 212, and the bottom support frame 216 to move, so that the bottom support frame 216 supports the goods from the bottom. This achieves multi-directional clamping and bottom support of the goods, effectively avoiding the situation of goods slipping when handling heavy or irregularly shaped goods. It improves the stability and reliability of the logistics robot in the process of handling goods, effectively avoids the occurrence of problems such as goods slipping, expands the application scope of the logistics robot, and further expands the application scenarios and use value of the logistics robot.

[0043] It should be noted that the specific models and specifications of the rotating component 102, moving component 103, connecting component 104, first electric push rod 203, and second electric push rod 210 in the lightweight logistics robot gripping device need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] Furthermore, the power supply and operating principle of the rotating component 102, moving component 103, connecting component 104, first electric push rod 203, and second electric push rod 210 in the lightweight logistics robot gripping device are clear to those skilled in the art and will not be described in detail here.

[0045] Furthermore, the working principles and wiring methods of the rotating component 102, moving component 103, connecting component 104, first electric push rod 203, and second electric push rod 210 in the lightweight logistics robot gripping device are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
