TECHNICAL FIELD
[0001] The application relates to a material feeding mechanical hand material limiting structure. BACKGROUND
[0002] The material feeding mechanical hand is a mechanical device for automatically carrying workpieces in a production line or an automatic system, and a material feeding mechanical hand material limiting structure is usually matched with the material feeding mechanical hand during clamping of the workpiece, so as to prevent the workpiece from falling off.
[0003] In the existing mechanical hand, a pneumatic drive is usually used to enable the clamping rod on the main body to clamp the workpiece, and a tooth-shaped structure is arranged on the clamping rod to increase the friction between the clamping rod and the workpiece and prevent the workpiece from falling off the clamping rod. However, if the mechanical hand malfunctions, the workpiece may still fall off the clamping rod, and the workpiece cannot be continuously limited. Therefore, a material feeding mechanical hand material limiting structure needs to be provided to solve the above problems.
[0004] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information which does not constitute prior art. CONTENT OF THE UTILITY MODEL

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a material feeding mechanical hand material limiting structure, comprising a rack, a guide rail mounted on the rack, a guide plate slidably mounted on the guide rail, an adjusting mechanism mounted on the guide plate, the adjusting mechanism having a hanger, a clamping jaw mechanism mounted at the bottom of the hanger, the clamping jaw mechanism comprising a cylinder fixed to the bottom of the hanger, three sets of jaw heads, the three sets of jaw heads being slidably mounted at the bottom of the cylinder, a limiting unit being mounted at the bottom end of the jaw head, the limiting unit comprising a base fixed to the end of the jaw head, a limiting rod rotatably connected to the base at the middle, and a spring arranged between the limiting rod and the base.
[0007] Preferably, the limiting rod extends outwardly from the inside and outside of the jaw head at both ends.
[0008] Preferably, the limiting rod is made of rubber material.
[0009] Preferably, the adjusting mechanism further comprises a first air cylinder mounted on the guide plate, and the hanger is connected to the output end of the first air cylinder.
[0010] Preferably, a second cylinder is installed on the side of the hanger, and the second cylinder has a limiting end.
[0011] The beneficial effects of this application are as follows: The material feeding robot anti-dislodgement structure provided by this application, when the claw grips the workpiece, through the rotation of the limiting rod and the action of the extended end of the limiting rod, and with the mutual cooperation of the limiting rod and the spring, the workpiece falling is buffered to prevent damage to the workpiece, thereby achieving the effect of limiting the workpiece held by the clamping rod.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0021] like Figures 1-2 As shown, this application provides a feeding robot anti-dislodging structure, including a frame 1 and a guide rail 11 mounted on the frame 1, a guide plate 12 slidably mounted on the guide rail 11, and a screw drive structure 13 mounted on the guide rail 11. The screw drive structure 13 is connected to the guide plate 12 to drive the guide plate 12 to slide back and forth along the guide rail 11.
[0022] An adjustment mechanism 2 is installed on the guide plate 12. The adjustment mechanism 2 includes a first cylinder 21 fixed on the guide plate 12 and a hanger 23 installed on the output end of the first cylinder 21. A gripper mechanism 3 for clamping workpieces is installed on the hanger 23. The first cylinder 21 is adapted to drive the hanger 23 to move up and down, and indirectly drive the gripper mechanism 3 on the hanger 23 to move, thereby driving the gripper mechanism 3 to move closer to the workpiece.
[0023] Meanwhile, a second cylinder 24 is installed on the side of the hanger 23. The end of the second cylinder 24 is provided with a limit end 241. The limit end 241 is suitable for limiting the displacement of the gripper mechanism 3 under the action of the second cylinder 24.
[0024] like Figures 2-3 As shown, the gripper mechanism 3 includes a cylinder 31 fixed below the hanger 23 and three sets of gripper heads 32 disposed at the bottom of the cylinder 31. The three sets of gripper heads 32 are slidably mounted on the cylinder 31, so that the three sets of gripper heads 32 are adapted to retract or open towards the center of the cylinder 31. In this application, the gripper mechanism 3 is pneumatically driven to drive the three sets of gripper heads 32 to move and clamp the workpiece.
[0025] During the gripping process of the gripper mechanism 3, the three sets of grippers 32 move synchronously through pneumatic action, causing the three sets of grippers 32 to contract or expand relative to each other. When the three sets of grippers 32 are in a contracted state, the gripper mechanism 3 is suitable for clamping the workpiece through the inside of the grippers 32. When the three sets of grippers 32 are in an expanded state, the gripper mechanism 3 is suitable for expanding and contracting to clamp the ring-shaped workpiece through the outside of the grippers 32.
[0026] A limiting unit 33 for preventing workpiece detachment is installed at the end of the claw 32. The limiting unit 33 includes a base 331 fixed to the end of the claw 32 and a limiting rod 332 disposed on the base 331. The limiting rod 332 is rotatably connected to the base 331 at the middle, and the limiting rod 332 extends to both the inner and outer sides of the claw 32 with protruding ends (not shown in the figure). The limiting rod 332 is made of rubber, and a spring 333 is connected between the limiting rod 332 and the base 331. The spring 333 is suitable for resetting the limiting rod 332 after rotation.
[0027] In summary, when the gripper 32 clamps the workpiece, the rotation of the limiting rod 332, combined with the action of the extended end of the limiting rod 332, and the cooperation between the limiting rod 332 and the spring 333, buffers the workpiece falling to prevent damage to the workpiece, thus achieving the effect of limiting the workpiece clamped by the gripper.
[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations are possible for those skilled in the art. Any improvements and modifications made within the spirit and principles of this application, without departing from its principles, should also be considered within the scope of protection of this application.
