Technical Field
[0001] This utility model belongs to the field of multi-claw robotic arm technology, and in particular relates to a wear-resistant and non-slip multi-claw robotic arm. Background Technology
[0002] Multi-claw robotic arms, as a commonly used modern gripping component, primarily function to grasp and transport items for subsequent transport. However, existing multi-claw robotic arms lack a detachment alarm component, so when items fall inside the robotic arm, they cannot alert nearby staff, potentially causing the robotic arm to become detached and require adjustment. Summary of the Invention
[0003] To achieve the above objectives, the present invention adopts the following technical solution:
[0004] A wear-resistant and non-slip multi-claw manipulator includes a gripper mechanism and a connecting plate. A first transmission mechanism is fixedly connected to the top of the connecting plate, and a second transmission mechanism is fixedly connected to the tail end of the first transmission mechanism. The gripper mechanism includes a connecting plate, and a clamping rod is hinged to the bottom of the connecting plate. Four clamping rods are provided, and an anti-slip sleeve is wrapped around the outer surface of the clamping rod. A first electric telescopic rod is hinged to the bottom of the connecting plate. Four first electric telescopic rods are provided, and the tail end of the first electric telescopic rod is hinged to the back of the clamping rod.
[0005] A pressure sensor is fixedly connected to the inner side of the connecting piece, and the pressure sensor is located inside the clamping rod. A buzzer is fixedly connected to the top of the connecting piece.
[0006] The first transmission mechanism includes connecting rods, which are fixedly connected to the top of the connecting plate. There are two connecting rods, and the connecting rods are located outside the buzzer. The tail ends of the two connecting rods are fixedly connected to electric push rods, and the tail ends of the electric push rods are hinged to connecting shells.
[0007] Preferably, a second electric telescopic rod is hinged to one side of the connecting shell, and the tail end of the second electric telescopic rod is hinged to the bottom of the electric push rod.
[0008] Preferably, the second transmission mechanism includes a transmission disk, which is fixedly connected to the bottom of the connecting housing.
[0009] Preferably, a motor is fixedly connected to the bottom of the transmission disk, and the output end of the motor is connected to the transmission disk.
[0010] Preferably, a shielding shell is fixedly connected to the outer surface of the motor.
[0011] Preferably, the outer surface of the shielding shell is fixedly connected with a fixing plate, and there are two fixing plates. The top of the fixing plate is provided with a threaded fixing hole, and there are four threaded fixing holes.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] This invention incorporates a pressure sensor and a buzzer. When an object moves to the inside of the connecting piece, it exerts pressure on the pressure sensor. When the object falls, the pressure sensor transmits electrical energy to the inside of the buzzer. At this time, the small paddle inside the buzzer vibrates at a high frequency, producing a sharp sound, alerting nearby staff that the robotic arm is not gripping tightly and needs adjustment.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0020] Reference Figures 1-4A wear-resistant and non-slip multi-claw manipulator includes a gripper mechanism 1 and a connecting plate 101. A first transmission mechanism 2 is fixedly connected to the top of the connecting plate 101, and a second transmission mechanism 3 is fixedly connected to the tail end of the first transmission mechanism 2. The gripper mechanism 1 includes the connecting plate 101, a clamping rod 102, an anti-slip sleeve 103, a first electric telescopic rod 104, a pressure sensor 105, and a buzzer 106. It grips items to be transported for subsequent transport. The connecting plate 101 provides fixing points for the clamping rod 102, the first electric telescopic rod 104, the pressure sensor 105, the buzzer 106, and the connecting rod 101, which are fixedly connected to its outer surface. The bottom of the connecting plate 101 is hinged to the clamping rod 102. Four clamping rods 102 are provided. Driven by the first electric telescopic rod 104, the clamping rods 102 move outward to facilitate the entry of items into the inner side of the clamping rods 102. Simultaneously, when the first electric telescopic rod 104 extends, the clamping rods 102 move inward to generate clamping force and secure the items for subsequent transport. An anti-slip sleeve 103, made of rubber, is attached to the outer surface of the clamping rods 102 and has several raised dots to increase the friction at the tail end of the clamping rods 102. Four first electric telescopic rods 104 are hinged to the bottom of the connecting piece 101, and the tail ends of the first electric telescopic rods 104 are hinged... Attached to the back of the clamping rod 102, when it is necessary to move an item to the inside of the clamping rod 102, the first electric telescopic rod 104 can be retracted via an external control component, causing the clamping rod 102 to move outward. When it is necessary to clamp an item, the first electric telescopic rod 104 can be extended via an external control component, causing the clamping rod 102 to move inward, thus clamping and fixing the item. The first transmission mechanism 2 includes a connecting rod 201, an electric push rod 202, a connecting shell 203, and a second electric telescopic rod 204, which drives the gripper mechanism 1 to swing so that the gripper mechanism 1 can subsequently grasp the item. The connecting rod 201 is fixedly connected to the top of the connecting piece 101. Two connecting rods 201 are provided, with the connecting rod 201 located outside the buzzer 106. The connecting rod 201 is fixedly connected to the top of the connecting piece 101, providing a fixing point for the electric push rod 202 fixedly connected to its tail end. The tail ends of the two connecting rods 201 are fixedly connected to the electric push rod 202. When it is necessary to adjust the position of the gripper mechanism 1, electrical energy can be transmitted to the interior of the electric push rod 202 via an external control component. At this time, the electric push rod 202 extends or retracts to adjust the position of the gripper mechanism 1. The tail end of the electric push rod 202 is hinged to a connecting shell 203, which is hinged to the tail end of the electric push rod 202, providing a connection point for the second electric telescopic rod 204 hinged to one side, and also providing a fixing point for the transmission disc 301 fixedly connected to its bottom.A second electric telescopic rod 204 is hinged to one side of the connecting shell 203, and the tail end of the second electric telescopic rod 204 is hinged to the bottom of the electric push rod 202. When it is necessary to swing the gripper mechanism 1, electrical energy can be transmitted to the interior of the second electric telescopic rod 204 via an external control component. At this time, the second electric telescopic rod 204 extends or retracts, causing the gripper mechanism 1 to swing, so that the gripper mechanism 1 can subsequently hold the object. The second transmission mechanism 3 includes a transmission disk 301 and a motor 30. 2. The shielding shell 303, the fixing plate 304, and the threaded fixing hole 305 drive the gripper mechanism 1 to rotate, completing the subsequent transportation of the items. The transmission disk 301 is fixedly connected to the bottom of the connecting shell 203. The transmission disk 301 rotates under the drive of the motor 302, which drives the gripper mechanism 1 to rotate via the connecting shell 203, so as to facilitate the subsequent transportation of items. The bottom of the transmission disk 301 is fixedly connected to the motor 302, and the output end of the motor 302 is connected to the transmission disk 301. The connection provides a fixing point for the shielding shell 303, which is fixedly connected to its outer surface. When it is necessary to transport items, electrical energy can be transmitted to the inside of the motor 302 via an external control component. At this time, the motor 302 transmits rotational power to the inside of the transmission disk 301 through electromagnetic effect. The shielding shell 303 is fixedly connected to the outer surface of the motor 302, providing a shield to prevent water from the external environment from entering the inside of the motor 302. Two fixing plates 304 are fixedly connected to the outer surface of the shielding shell 303. Each fixing plate 304 provides a fixing point for a threaded fixing hole 305 extending through its top. Four threaded fixing holes 305 are provided at the top of each fixing plate 304. When the robot needs to be fixed, external bolts can be inserted into the threaded fixing holes 305 by external force, and then into the external fixing plane to complete the overall fixing of the robot.
[0021] Reference Figure 1 , Figure 3 and Figure 4A pressure sensor 105 is fixedly connected to the inner side of the connecting piece 101, and the pressure sensor 105 is located inside the clamping rod 102. The pressure sensor 105 is fixedly connected to the inner side of the connecting piece 101. When the object moves to the inner side of the connecting piece 101, it generates pressure on the pressure sensor 105. When the object falls, the pressure sensor 105 transmits electrical energy to the inside of the buzzer 106. The buzzer 106 is fixedly connected to the top of the connecting piece 101. When electrical energy is transmitted to the inside of the buzzer 106 through the pressure sensor 105, the small lever inside the buzzer 106 vibrates at a high frequency and emits a sharp sound, reminding the surrounding staff that the robotic arm is not gripping tightly and needs adjustment.
[0022] The functional principle of this utility model can be explained through the following operation: First, the external bolt is inserted into the threaded fixing hole 305 and then into the external fixing plane to fix the entire robot arm. When it is necessary to clamp an item, the external control component can transmit electrical energy to the inside of the second electric telescopic rod 204 and the electric push rod 202 to adjust the designated position of the gripper mechanism 1. Then, the external control component drives the first electric telescopic rod 104 to retract, causing the clamping rod 102 to move outward. After that, the external control component drives the first electric telescopic rod 104 to extend, causing the clamping rod 102 to move inward, thus completing the clamping and fixing of the item. Then, the external control component transmits electrical energy to the inside of the motor 302. At this time, the motor 302 transmits rotational power to the inside of the transmission plate 301 through electromagnetic effect. The transmission plate 301 drives the gripper mechanism 1 to rotate, so that the item can be released later.
