Description

Technical Field

[0001] This utility model relates to the field of circular part feeding technology, and in particular to an automatic feeding device for gripping circular parts. Background Technology

[0002] Against the backdrop of ever-accelerating modern industrial production, efficient, precise, and automated production processes have become core elements for enterprises to enhance their competitiveness. Especially in many fields involving the processing of circular parts, such as machinery manufacturing, electronic equipment production, and automotive parts manufacturing, the efficiency and quality of the circular part loading process, as the initial stage of production, have a crucial impact on overall production efficiency.

[0003] However, in existing technologies, traditional methods of feeding round parts mostly rely on manual operation. Workers need to manually move the round parts from the storage area to the processing equipment and then place them one by one on the processing station. This method has the problems of high labor costs and worker fatigue under long-term, high-intensity work conditions, which increases the rate of operational errors. To solve the shortcomings of manual feeding, some companies have tried to use devices such as vibratory feeders to sort the round parts and then transport them to the feeding position. However, these devices have obvious limitations. First, they have extremely strict requirements on the specifications and shape of the round parts and can only be used for a few specific sizes and shapes of round parts. Once the size, thickness or material of the round parts changes, the equipment needs to be adjusted on a large scale or may even become unusable. Second, these devices have poor stability and accuracy in the process of gripping and handling round parts. Round parts are very prone to positional displacement and falling during the transfer process, which seriously affects the accuracy of feeding and the continuity of production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where it is difficult to accurately orient the robotic arm during gripping, and uneven force is easily generated during the gripping process. If this happens, the round parts are likely to fall off during continued transportation. Therefore, an automatic feeding device for gripping round parts is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for gripping circular parts, including a positioning frame, a turntable fixedly connected to the bottom of the positioning frame, a movable block slidably connected to the outer wall of the positioning frame, and a gripping mechanism fixedly connected to one side of the movable block;

[0006] The clamping mechanism includes a support platform, a fixed platform, a turntable, and a clamping plate. The fixed platform is fixedly installed on the lower surface of the end of the support platform, and the turntable is rotatably installed on the upper surface of the fixed platform. A connecting rod is fixedly installed on one side of the top of the clamping plate, and a protrusion is fixedly installed on the upper surface of the connecting rod. The protrusion is slidably connected inside the turntable.

[0007] Preferably, a strip hole is provided at the junction of the turntable and the protrusion, and the turntable is located on the upper surface of the connecting rod.

[0008] Preferably, a geared motor is fixedly installed on the top of the support platform, and a rocker arm is fixedly connected to the output end of the geared motor.

[0009] Preferably, one end of the rocker arm is rotatably connected to the edge of the turntable, and the axis of the output shaft of the geared motor and the axis of the turntable are on the same straight line.

[0010] Preferably, a receiving groove is provided at the junction of the fixed platform and the connecting rod.

[0011] Preferably, an arc-shaped hole is provided at the center of the turntable, and the bolts used to connect the fixed platform and the support platform are located inside the arc-shaped hole.

[0012] Preferably, a threaded rod is rotatably mounted inside the positioning frame, and the threaded rod is threadedly connected to the movable block.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a circular part is clamped by setting a clamping plate that is also arc-shaped. In actual use, the turntable drives multiple connecting rods through the protrusion to change the position of the clamping plate and complete the clamping and fixing of the circular part. The distance between the multiple clamping plates is always consistent. When clamping, it can ensure that the circular part is subjected to uniform force. During the loading and transportation process, the probability of the circular part falling off is reduced. Even if it is subjected to external force, it will not affect the circular part, thus ensuring the assembly accuracy.

[0015] 2. In this utility model, by using the geared motor and the rocker arm in combination, the stability of the support platform is not affected, while the turntable has enough rotation space. The presence of the receiving groove provides the connecting rod with room to move, while the arc-shaped hole restricts the rotation path of the disc and prevents misalignment.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an automatic feeding device for gripping round parts, including a positioning frame 1, a turntable 3 fixedly connected to the bottom of the positioning frame 1, a movable block 5 slidably connected to the outer wall of the positioning frame 1, and a gripping mechanism 4 fixedly connected to one side of the movable block 5.

[0024] The clamping mechanism 4 includes a support platform 41, a fixed platform 43, a turntable 44, and a clamping plate 46. The fixed platform 43 is fixedly installed on the lower surface of the end of the support platform 41. The turntable 44 is rotatably installed on the upper surface of the fixed platform 43. A connecting rod 47 is fixedly installed on one side of the top of the clamping plate 46. A protrusion 48 is fixedly installed on the upper surface of the connecting rod 47. The protrusion 48 is slidably connected to the inside of the turntable 44. A strip hole 49 is provided at the junction of the turntable 44 and the protrusion 48. The turntable 44 is located on the upper surface of the connecting rod 47.

[0025] The specific settings and functions of this embodiment are described below. The positioning frame 1 is used to determine the position of the entire device. The turntable 3 at its bottom is used to connect with the rotating mechanism, so that the device can adjust its direction. In actual use, the movable block 5 moves up and down along the positioning frame 1, bringing the clamping mechanism 4 above the circular part, so that the clamping plates 46 can be evenly distributed around the circular part. Then, the turntable 44 is driven. During the rotation of the turntable 44, the strip hole 49 will drive the connecting rod 47 through the protrusion 48, forcing the clamping plate 46 to move towards the center of the turntable 44, thus completing the clamping and fixing of the circular part. The existence of the strip hole 49 provides sufficient space for the protrusion 48 to move. After the clamping plate 46 has clamped the circular part, the movable block 5 drives the circular part upward. The rotating mechanism drives the turntable 3 to directly change the direction of the device and bring the circular part to the designated position. The clamping plate 46 is specifically an arc-shaped plate that can adapt to the curvature of the circular part.

[0026] Example 2: Figure 3 and Figure 4 As shown, a geared motor 42 is fixedly installed on the top of the support platform 41. A rocker arm 45 is fixedly connected to the output end of the geared motor 42. One end of the rocker arm 45 is rotatably connected to the edge of the turntable 44. The axis of the output shaft of the geared motor 42 and the axis of the turntable 44 are on the same straight line. A receiving groove 411 is provided at the junction of the fixed platform 43 and the connecting rod 47. An arc-shaped hole 410 is provided at the center of the turntable 44. The bolts used to connect the fixed platform 43 and the support platform 41 are located inside the arc-shaped hole 410. A threaded rod 2 is rotatably installed inside the positioning frame 1. The threaded rod 2 is threadedly connected to the movable block 5.

[0027] The overall effect of this embodiment is that the output shaft of the geared motor 42 is connected to the rocker arm 45, and the other end of the rocker arm 45 is rotatably connected to the edge of the turntable 44. When the geared motor 42 is operating, the rocker arm 45 drives the turntable 44 to rotate, thereby providing a power source for the movement of the clamping plate 46. The receiving groove 411 in the fixed platform 43 is used to receive the connecting rod 47 and determine its movement path. The existence of the arc-shaped hole 410 not only ensures the connection stability between the fixed platform 43 and the support platform 41, but also determines the rotation path of the turntable 44, preventing structural misalignment. A servo motor is provided on the top of the positioning frame 1. The output shaft of the servo motor is connected to the threaded rod 2. The height of the movable block 5 is adjusted by driving the threaded rod 2. The servo motor and the geared motor 42 are controlled in coordination by a pre-written control program to realize the automation of the entire feeding process.

[0028] The usage and working principle of this device are as follows: During use, the turntable 3 is connected to the rotating mechanism. A servo motor connected to the threaded rod 2 is installed on the top of the positioning frame 1. The servo motor drives the threaded rod 2 to adjust the height of the movable block 5, bringing the clamping mechanism 4 above the circular part. This allows the clamping plates 46 to be evenly distributed around the circular part. Then, the reduction motor 42 is started. The reduction motor 42 drives the turntable 44 via the rocker arm 45. The rotation of the turntable 44 drives the connecting rod 47, forcing the clamping plates 46 to move towards the center of the turntable 44, thus clamping and fixing the circular part. During this process, the protrusion 48 moves along the slot 49, and the connecting rod 47 moves along the receiving groove 411. After the clamping plate 46 has clamped the circular part, the servo motor drives the threaded rod 2 to adjust the movable block 5. As the circular part is pulled upwards, the rotating mechanism drives the turntable 3 to directly change the direction of the device, ultimately bringing the circular part to the designated position. Once the designated position is reached, the reduction motor 42 is reversed to release the clamping plate 46 from the circular part, completing the loading operation.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
