Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent mechanical arms, and particularly relates to an intelligent mechanical arm for assembling a jewelry box. BACKGROUND

[0002] The traditional jewelry box assembly process is usually completed manually, but manual operation has the disadvantages of low efficiency, poor precision, and easy errors. With the continuous development of automation technology, more and more enterprises begin to seek intelligent and automated production methods to improve production efficiency, reduce production costs, and ensure product quality consistency. The existing mechanical arm has certain drawbacks in use. The connection between the two mechanical arms will be severely worn due to long-term rotation, and manual addition of oil is required to alleviate the wear. When the mechanical arm is controlled by the control end, it cannot clearly capture the picture in front of the mechanical arm, which may cause operation errors and affect the accuracy of the results. When using a clamping plate to clamp an object, the clamping plate itself may cause instability, which poses a certain safety hazard. Therefore, an industrial assembly mechanical arm is proposed to solve the above problems.

[0003] The prior art discloses an industrial assembly mechanical arm with the publication number CN207465227U. The oil inside the oil box is delivered to the brush through the delivery pipe, and the oil is automatically applied to the rotating part during the rotation of the rotating shaft. Because of the presence of the foam block, the oil will not be used excessively, and a benign cycle can be maintained. The compression spring can directly clamp the object by the elastic force of the spring, which is practical. In the case of sudden power failure of the mechanical arm, the spring can still clamp the object, avoiding the object from falling and eliminating safety hazards.

Several first springs 412 are fixedly installed between the first clamping plate 48 and the support plate 49. The first motor 421 drives the first clamping plate 48 to slide, thereby clamping the jewelry box body 52.

[0022] A second spring 420 is fixedly installed between the first limiting rod 415 and the third slide groove 419. Both the upper and lower ends of the first limiting rod 415 are set as inclined surfaces to facilitate the first limiting rod 415 to be reset by the elastic force of the second spring 420.

[0023] The first clamping plate 48 is slidably connected to the outer side of the rotating shaft 417, so that the rotating shaft 417 can drive the first clamping plate 48 to slide.

[0024] The positioning device includes a partition rod 51 and a connecting rod 53. The partition rod 51 is fixedly installed on the top of the workbench 1. Two connecting rods 53 are symmetrically arranged and fixedly installed on the side wall of the jewelry box body 52. ​​Both connecting rods 53 have screw holes on their surfaces. The jewelry box body 52 is assembled through the screw holes on the surface of the connecting rods 53.

[0025] The positioning device also includes a first pressing rod 54 and a second pressing rod 57. The worktable 1 has a fourth sliding groove 55 and a second sliding groove 510.

The second limiting rod 512 is slidably installed inside the second sliding groove 510. The jewelry box body 52 is positioned by the second limiting rod 512.

[0026] A No. 3 spring 56 is fixedly installed between the No. 1 extrusion rod 54 and the No. 4 slide groove 55. The No. 1 extrusion rod 54 slides through the worktable 1. A No. 4 spring 59 is fixedly installed between the No. 2 extrusion rod 57 and the No. 1 slide groove 58. The side of the No. 2 extrusion rod 57 near the No. 1 extrusion rod 54 is set as an inclined surface. A No. 5 spring 511 is fixedly installed between the No. 2 limit rod 512 and the No. 2 slide groove 510. The side of the No. 2 limit rod 512 near the No. 2 extrusion rod 57 is set as an inclined surface to facilitate the extrusion and reset of the No. 2 limit rod 512.

[0027] The working principle and usage of this invention are explained in detail below: During use, when assembling the jewelry box body 52, the first robotic arm 3 and the second robotic arm 43 are adjusted to suitable positions, and the third robotic arm 45 is adjusted to a suitable angle via the starting device. At this time, the first motor 421 starts, driving the rotating shaft 417 to rotate. The rotating shaft 417 moves the first clamping plate 48, causing the sliding rod 411 to move closer to the second clamping plate 413. This movement of the sliding rod 411 also moves the support plate 49 and the first rubber pad 410 closer to the second clamping plate 413, thus clamping the jewelry box body 52. ​​The softness of the first and second rubber pads effectively buffers the pressure on the jewelry box body 52, preventing damage to delicate jewelry. For minor scratches or indentations on the surface, when the first rubber pad 410 clamps the jewelry box body 52 to a certain extent, the jewelry box body 52 exerts a counter-pressure on the first rubber pad 410. Under pressure, the first rubber pad 410 moves towards the first clamping plate 48. The movement of the first rubber pad 410 towards the first clamping plate 48 causes the support plate 49 to move towards the first clamping plate 48. The movement of the support plate 49 towards the first clamping plate 48 compresses the sliding rod 411. The movement of the sliding rod 411 compresses the first limiting rod 415. The first limiting rod 415, under the compressive force, moves away from the sliding rod 411 and inserts into the limiting groove 418. The limiting groove 418 contains a sensor. When the first limiting rod 415 is inserted into the limiting groove 418, the sensor causes the first motor 421 to stop working to prevent over-clamping of the jewelry box body 52. ​​Over-clamping can cause slight deformation of the jewelry box shape, affecting its appearance.

[0028] After the jewelry box body 52 is clamped, the first robotic arm 3 and the second robotic arm 43 move the jewelry box body 52 to the top of the workbench 1. The hydraulic rod 42 is activated, which drives the second robotic arm 43 to slide. The sliding of the second robotic arm 43 drives the third robotic arm 45 to slide. The sliding of the third robotic arm 45 drives the jewelry box body 52 to slide. When the jewelry box body 52 slides to a certain distance, it will squeeze the first extrusion rod 54. The first extrusion rod 54 moves downward under the extrusion force and comes into contact with the second extrusion rod 57 and squeezes the second extrusion rod 57. The second extrusion rod 57 moves towards the second limit rod 512 under the extrusion force and squeezes the second limit rod 512. The second limit rod 512 moves upward under the extrusion force and positions the jewelry box body 52 to prevent the jewelry box body 52 from deviating, which would make it difficult to align the screw holes and thus affect the assembly efficiency of the jewelry box body 52.

[0029] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
