[0002] The automatic feeding device for open circlips is a support device for rapid feeding of circlips. There are a large number of processes for circlip assembly in an automated production line. The automatic feeding of circlips can improve the automation level of the equipment and reduce the manual cycle time. With the continuous development of technology, the manufacturing process requirements for the automatic feeding device of open circlips are also getting higher and higher.

[0003] The existing feeding devices for open circlips have certain drawbacks when in use. Firstly, the automation level of the existing feeding devices for open circlips is relatively low, and more manual operations are required. The feeding efficiency cannot well meet the requirements, and the labor cost is relatively high. It requires shutdown operations, which brings certain adverse effects to the actual use process. For this reason, we propose an automatic feeding device for open circlips. Summary of the Utility Model

[0022] As Figures 1-4 shown, an automatic feeding device for an open circlip includes a feeding unit support base 1. A circlip grasping unit 3 and a cylinder support 10 are arranged at the front position of the upper end of the feeding unit support base 1. A pinch prevention switching cylinder 6 is installed at the rear position of the upper end of the feeding unit support base 1. A circlip opening direction guide 14 and a circlip material column 15 are arranged at the upper end of the feeding unit support base 1. The circlip opening direction guide 14 is located outside the circlip material column 15. A counterweight 4 is installed at the top of the circlip material column 15. A cutting cylinder 2 is installed at the front end of the cylinder support 10. It can be flexibly applied to various devices that need to assemble circlips. Only the size of the guide and the blanking position, and the guiding position size need to be modified according to the specific circlip, and it has a certain degree of versatility and flexibility.

[0023] Further, a quick-release component 5 for the stock column is installed outside the snap ring stock column 15, an open snap ring 13 is arranged on the outer wall of the snap ring stock column 15, a quick-release component 8 for the cutting stock sliding groove cover is positioned at the top of the feeding unit support base 1, and a support base 11 is positioned at the bottom of the feeding unit support base 1.

[0024] Further, a snap ring picking position 16 and a picking position laser sensor 9 are arranged on the feeding unit support base 1 at the position of the snap ring grasping unit 3, a snap ring blanking position 17 and a blanking position laser sensor 7 are arranged on the feeding unit support base 1 at the position of the snap ring stock column 15, and a grasping frame 12 is arranged at the bottom of the snap ring grasping unit 3.

[0025] Further, the operator stacks all the open snap rings 13 of the incoming material along the opening direction of the pre-guiding component onto the outer wall of the snap ring stock column 15, and at the same time, a counterweight 4 is positioned and clamped on the topmost group of open snap rings 13, and the bottom of the feeding unit support base 1 is installed and supported through the support base 11.

[0026] Further, the picking position laser sensor 9 monitors the state of the open snap ring 13 at the snap ring picking position 16, and the snap ring grasping unit 3 controls the grasping frame 12 to perform grasping at the snap ring picking position 16, and the blanking position laser sensor 7 monitors the state of the open snap ring 13 at the snap ring blanking position 17.

[0027] Further, the snap ring grasping unit 3 is installed on the side of the feeding unit support base 1 through a cylinder support 10, and the feeding unit support base 1 and the anti-pinch switching cylinder 6 are fixed by bolts.

[0028] Further, when all the open snap rings 13 are stacked onto the snap ring stock column 15, the equipment automatically detects to ensure that the number of open snap rings 13 is sufficient. At this time, the blanking position laser sensor 7 detects that there is an open snap ring 13 at the snap ring blanking position 17, and the cutting cylinder on the side horizontally cuts the open snap ring 13 at the snap ring blanking position 17 to the snap ring picking position 16. Moreover, the switching block and the switching guide groove should be designed according to the snap ring size. After switching in place, the picking position laser sensor 9 detects that there is an open snap ring 13 at the snap ring picking position 16, and the clamping jaw of the equipment for picking the open snap ring 13 automatically takes away the open snap ring 13 at the snap ring picking position 16.

[0029] Further, after the open snap ring 13 is automatically taken away, the picking position laser sensor 9 detects that the product does not exist. At this time, the cutting cylinder starts to reciprocally switch the open snap ring 13 to ensure the continuous automatic operation of the equipment.

[0030] The upper servo electric cylinder drives the grasping unit, and two groups of snap ring automatic feeding units are arranged below, so as to realize the automatic feeding of the snap ring. At the same time, the two groups of snap rings can ensure that the equipment does not stop running, and the feeding cycle is once every 2 hours.

[0031] Working principle: The utility model includes a feeding unit support base 1, a cutting cylinder 2, a circlip grasping unit 3, a counterweight 4, a material column quick-release part 5, an anti-pinch hand switching cylinder 6, a blanking position laser sensor 7, a cutting sliding groove cover plate quick-release part 8, a picking position laser sensor 9, a cylinder support 10, a support base 11, a grasping frame 12, an open circlip 13, a circlip opening direction guide part 14, a circlip material column 15, a circlip picking position 16, a circlip blanking position 17, 18, which can be flexibly applied to various devices that need to assemble circlips. Only the guide part size and the blanking position need to be modified according to the specific circlip, and the guide position size can be adjusted accordingly, having a certain degree of versatility and flexibility.

[0032] Manually stack all the incoming bagged circlips onto the feeding column according to the opening direction of the pre-guide part, and at the same time press the configuration block on the topmost circlip. The device automatically detects the counterweight to ensure that there are enough circlips; at this time, the blanking position laser sensor detects that there is a circlip at the blanking position, and the cutting cylinder horizontally cuts the circlip at the blanking position to the picking position. The switching block and the switching guide groove should be designed according to the circlip size; after switching in place, the picking position sensor detects that there is a circlip at the picking position, and the clamping jaw of the device for picking the circlip automatically takes away the circlip at the picking position. At this time, the picking position laser sensor detects that the product does not exist, and the cutting cylinder starts to reciprocally switch the circlips to ensure the continuous automatic operation of the device.

[0033] The quick-release function of the circlip material column and the quick-release of the cutting groove cover plate of this mechanism ensure that when the size or appearance of the incoming circlip is out of tolerance and causes the mechanism to jam, the device can be quickly restored to operation using the quick-release function.

[0034] There are a large number of circlip assembly processes in the automated production line. The automatic feeding of circlips can improve the automation level of the device and reduce the manual cycle time. This mechanism can achieve the automatic feeding function of different circlips only by changing the corresponding size according to the corresponding circlip.

[0035] This mechanism is used in the circlip assembly process of the steering gear assembly production line. This mechanism is mainly used for the semi-automatic feeding of open circlips to reduce the frequency of manual feeding. This mechanism ensures the consistent opening direction of the circlips through the pre-guide design of the circlips, ensures that the circlips smoothly fall into the pushing groove one by one through the counterweight, detects whether there is a circlip at the blanking position through a set of opposed laser sensors, switches the circlip at the blanking position to the grasping position through the cutting cylinder, and at the same time detects whether there is a circlip at the picking position through another set of laser sensors. The entire mechanism design has a quick-release design to achieve rapid processing in case the circlip gets stuck in the material channel and reduce the equipment downtime.
