Description

Technical Field

[0001] The utility model relates to the technical field of automatic discharging, in particular to an automatic discharging mechanical arm device. Background Art

[0002] A robotic arm is a high-precision, high-speed dispensing robot. It's ideal for small-batch production, improving productivity. In addition to dispensing, it can handle a variety of tasks, including UV irradiation, part placement, screw locking, and circuit board cutting. The mechanical structure of a robotic arm is the foundation of its freedom of movement. It typically consists of multiple joints and connecting rods, each of which is coordinated by a drive system consisting of a motor and a reducer, enabling the arm's freedom of movement.

[0003] After searching, the existing patent (Announcement No.: CN220998325 U) discloses a high-efficiency automatic feeding mechanism for a paper nail robot arm, which relates to the technical field of automatic feeding of paper nails. It includes a collection bin, a rotating rod and a movable rack. A fixed plate is installed on the right side of the collection bin, and a rotating rod is provided above the fixed plate. A mechanical arm assembly is provided below the connecting plate. An inner groove is installed above the fixed plate, and a fixed baffle is provided on the right side of the fixed plate. The high-efficiency automatic feeding mechanism for a paper nail robot arm is provided with a mechanical arm assembly and an electromagnet. When the servo motor is started, the servo motor can drive the rotating rod to rotate through the output shaft. The rotating rod can drive the mechanical arm assembly to move through the connecting plate. Then the mechanical arm assembly drives the electromagnet below to move.

[0026] Example 1

[0027] The preferred embodiment of the automatic discharging robot arm device provided by the utility model is as follows Figures 1 to 5 As shown: An automatic discharging robotic arm device, including a material box 1, a rotating chassis 2 is fixedly installed on one side surface of the material box 1, a bearing seat 3 is fixedly installed on the bottom of the casing of the rotating chassis 2, a support frame 4 is embedded and fixedly installed inside the bearing seat 3, a connecting block 5 is installed at the bottom of the rod body of the support frame 4, a No. 1 fixing pin 7 is fixedly installed on the top surface of the connecting block 5, a No. 1 connecting rod 8 is rotatably installed above the No. 1 fixing pin 7, a No. 1 turntable 9 is provided at the bottom of one side of the No. 1 connecting rod 8, a No. 1 motor 10 is provided on the bottom surface of the No. 1 turntable 9, and a connecting frame 11 is fixedly connected to the top of the upper part of the rod body of the support frame 4.

[0028] In this embodiment, by setting the No. 1 fixing pin 7 and the No. 1 connecting rod 8, the No. 1 fixing pin 7 is respectively set at both ends of the No. 1 connecting rod 8 and combined with the No. 1 turntable 9 and the limit block 6, so that when the No. 1 motor 10 drives the No. 1 turntable 9 to rotate, the No. 1 connecting rod 8 drives the connecting block 5 to drive the support frame 4 to start rotating, so as to avoid the gear teeth being misaligned and causing the teeth to be stuck or damaged when the gear teeth are engaged, which is conducive to the support frame 4 to form a fan-shaped reciprocating rotation.

[0029] In this embodiment, the bottom of the support frame 4 is vertically embedded in the interior of the casing of the rotating chassis 2. The connecting block 5 and the limit block 6 are an integrated structure. The limit block 6 is located at the connection between the material box 1 and the rotating chassis 2.

[0031] Example 2

[0032] On the basis of Example 1, a preferred embodiment of an automatic discharging robot arm device provided by the present invention is as follows: Figures 1 to 5 As shown: a lifting box 12 is fixedly installed on one end of the rod body of the connecting frame 11, a No. 2 motor 13 is fixedly installed inside the casing of the lifting box 12, a transmission screw 14 is fixedly installed on the bottom output end of the No. 2 motor 13, and a nut sleeve rod 15 is provided on the rod body below the transmission screw 14 in threaded engagement connection. A positioning rod 16 is fixedly installed on the bottom surface of the casing of the lifting box 12, a positioning block 17 is provided below the rod body of the positioning rod 16, a guide block 18 is fixedly installed on the bottom of the rod body of the nut sleeve rod 15, an electromagnetic suction cup 19 is slidably installed on the outer side of the guide block 18, a No. 3 motor 20 is fixedly installed on the bottom surface of the guide block 18, a No. 2 turntable 21 is fixedly installed on the output end of the No. 3 motor 20, a No. 2 fixing pin 22 is fixedly provided on the surface of the No. 2 turntable 21, a No. 2 connecting rod 23 is rotatably installed above the No. 2 fixing pin 22, and a fixing block 24 is rotatably provided below the rod body of the No. 2 connecting rod 23.

[0033] In this embodiment, by setting the guide block 18 and the No. 3 motor 20, according to the setting of the No. 3 motor 20, when the No. 3 motor 20 drives the No. 2 turntable 21 to rotate, the No. 2 connecting rod 23 connected to the No. 2 turntable 21 through the No. 2 fixing pin 22 follows and moves up and down. At the same time, the bottom of the fixed block 24 is fixed to the electromagnetic suction cup 19, so that the electromagnetic suction cup 19 moves up and down with the speed of rotation of the No. 2 turntable 21, and a vibrating state is formed when viewed from the outside, which is convenient for screening the row of nails adsorbed on the electromagnetic suction cup 19, thereby ensuring that no nails fall off when the row of nails are moved.

[0034] In this embodiment, the positioning rod 16 is arranged in a mirror image on both sides of the transmission screw 14, and the top of the rod body of the positioning rod 16 is fixed to the bottom surface of the lifting box 12. The setting of the positioning rod 16 facilitates the protection of the transmission screw 14 to prevent external force from touching the transmission screw 14 and causing damage to it.

[0035] In this embodiment, the nut sleeve rod 15 vertically penetrates the center of the positioning block 17, and the surface of the nut sleeve rod 15 and the interior of the positioning block 17 are welded and fixedly connected. The positioning rod 16 synchronously vertically penetrates the positioning block 17, and the surface of the positioning rod 16 and the two sides of the positioning block 17 are movably connected. Through the setting of the positioning block 17, it is convenient to connect the nut sleeve rod 15 and the positioning rod 16, so that when the transmission screw 14 rotates, the nut sleeve rod 15 remains stable and can move up and down along the positioning rod 16.

[0036] In this embodiment, the guide block 18 has a cylindrical structure. The bottom of the guide block 18 is embedded in the inner cavity of the electromagnetic suction cup 19. The surface of the guide block 18 is mirror-symmetrically provided with sliding grooves on both sides to fit with the top of the electromagnetic suction cup 19. Through the arrangement of the guide block 18 and the electromagnetic suction cup 19, the electromagnetic suction cup 19 can move up and down along the guide block 18 when it starts to vibrate following the power output by the No. 3 motor 20, which is conducive to the electromagnetic suction cup 19 forming a vibration shape to screen the nails.

The electromagnetic suction cup 19 is vertically located above the center line of the inner groove of the material box 1. The setting of the electromagnetic suction cup 19 facilitates the adsorption and transfer of the rows of nails inside the material box 1.

[0038] The working principle and use process of the present invention are as follows: First, the No. 2 motor 13 inside the lifting box 12 arranged above the top of the material box 1 starts to output power to the transmission screw 14 installed on the output end, so that it rotates, so that the nut sleeve 15 starts to move by engaging with the thread of the transmission screw 14, and the nut sleeve 15 is restrained by the setting of the positioning rod 16 and the positioning block 17, and can only move up and down along the positioning rod 16, so that the electromagnetic suction cup 19 arranged at the bottom of the nut sleeve 15 will drop into the inner groove of the material box 1 to adsorb the material, and after the adsorption is completed, the No. 2 motor 13 starts to drive the transmission screw 14 to operate in the reverse direction, so that the electromagnetic suction cup 19 starts to rise and disengage. Inside the material box 1, while the electromagnetic suction cup 19 is rising, the No. 3 motor 20 starts to drive the No. 2 turntable 21 to start rotating, and the No. 2 connecting rod 23 is driven by the No. 2 turntable 21, so that the electromagnetic suction cup 19 moves up and down along the guide block 18 at the frequency of the rotation of the No. 2 turntable 21, so that the material that is not firmly adsorbed on the bottom surface of the electromagnetic suction cup 19 falls into the material trough of the material box 1, and then the No. 1 motor 10 arranged inside the rotating chassis 2 starts to drive the No. 1 turntable 9 installed on the output end to rotate, so that the support frame 4 starts to rotate through the connection block 5 and the No. 1 connecting rod 8 to transfer the electromagnetic suction cup 19 from the top of the material box 1 and put it into the next process of producing materials.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
