[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical ideas claimed for protection by the present invention. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.
[0035] like Figures 1 to 5 As shown, a circular ring feeding device in an embodiment of the utility model includes a conveying device 100, a feeding device 200, a rejecting device 300, a reflow trough 400, a correction mechanism 500 and a baffle 600.
[0036] The conveying device 100 is used to drive the ring to move from left to right; in fact, the conveying device 100 can be a conveying mechanism such as a chain drive or a belt drive, which can drive the ring to move from left to right; the baffle 600 is set on the right side of the conveyor and is used to prevent the ring from continuing to move to the right. When the conveying device 100 drives the ring to move from left to right until it abuts against the left side of the baffle 600, the ring stops moving right relative to the conveying device 100, and an external material moving mechanism (such as a material moving robot arm or a three-axis translation table cooperates with a clamping mechanism) transfers the rightmost one or more rings to the external continuous punching machine for processing; the ring on the conveying device 100 continues to move right until it abuts against the baffle 600, and is thus transferred to the external continuous punching machine in groups in cooperation with the external material moving device.
[0037] The feeding device 200 is arranged on the front side of the left part of the conveying device 100 and is used to transfer the ring to the left part of the conveying device 100; the feeding device 200 can include a material collecting trough and a material transfer robot arm or a three-axis translation platform with a clamping mechanism to achieve the transfer of the ring to the left part of the conveying device 100.
[0038] It should be noted that, in the present invention, the outer diameter of the ring to be transferred is greater than the length of the ring (specifically determined according to the design requirements of the front bushing of the corresponding automobile suspension swing arm). Through observation tests, it can be known that under the constraint of the shape of the ring, there are three postures when the ring is transferred to the conveying device 100. The first is the opening facing up and down, the second is the opening facing front and back, and the third is the left and right. Since the ring enters the external continuous punching machine in an up and down manner, the ring in the second and third postures must be processed.
[0039] The rejection device 300 is arranged at the rear side of the middle part of the conveying device 100 and is used to push the front-to-back facing ring forward away from the conveying device 100; the extraction device can be an image recognition device in conjunction with a telescopic rod. When a ring in the second posture is identified, the rejection device 300 pushes the ring in the second posture away from the conveying device 100 to prevent the ring in the second posture from continuing to move right.
[0040] The reflux trough 400 is arranged on the front side of the middle part of the conveying device 100 and the feed port is opposite to the output end of the rejection device 300 and is used to re-convey the ring to the feeding device 200; in fact, the discharge port of the reflux trough 400 is connected to the collecting trough of the feeding device 200 to prepare for re-moving the ring to the left part of the conveying device 100.
[0041] The correction mechanism 500 is arranged on the right side of the rejection device 300 and is used to move the circular ring facing left and right to the up and down direction; the correction mechanism 500 can be a correction robot or a toggle block, which can correct the circular ring in the third position by rotating it through 90 degrees to the circular ring in the first position, and the conveying device 100 continues to drive the circular ring to move right; so that the circular rings between the correction mechanism 500 and the baffle 600 are all in the first position, ensuring that the opening of the circular ring transferred to the external continuous punching machine is facing up and down.
[0042] The circular ring loading equipment of the utility model cooperates with each other through the conveying device 100, the feeding device 200, the rejection device 300, the reflow trough 400, the correction mechanism 500 and the baffle 600, which can drive the circular ring to move from left to right to the right part of the conveying device 100, and ensure that the opening of the circular ring located on the right part of the conveying device 100 is moved away by the external material moving mechanism in an upward and downward direction, with lower manual participation and reduced labor intensity.
[0043] It is worth mentioning that Figure 2As shown, the rejecting device 300 preferably includes a rejecting cylinder 310 arranged at the rear side of the middle part of the conveying device 100, a push plate 320 installed at the output end of the front side of the rejecting cylinder 310, a distance sensor 330 arranged on the left side of the rejecting cylinder 310 and above the conveying device 100 for detecting the height of the ring, and a first photoelectric switch 340 arranged in front of the rejecting cylinder 310 and above the conveying device 100 for detecting the ring. The distance sensor 330 is communicatively connected with the first photoelectric switch 340, and the conveying device 100 and the rejecting cylinder 310 are communicatively connected with the first photoelectric switch 340. In fact, the lower end or the lower side of the ring is against the upper conveying surface of the conveying device 100. Therefore, by detecting the distance between the upper end or the upper side of the ring through the distance sensor 330, the actual height of the ring can be determined; for the ring in the first posture, the distance sensor 330 can detect that the two positions of the ring are the same (the left and right parts of the ring), and the ring directly moves to the right through the push plate 320; for the ring in the second posture, the distance sensor 330 detects that the height of the ring is changing (because the upper side is a convex arc surface), and sends a signal to the first photoelectric switch 340. When the second When the ring in the first posture reaches the push plate 320, the first photoelectric switch 340 can first detect the right part of the ring and pass through the ring, send a signal to the conveying device 100 to stop the conveying device 100, and send a signal to the rejection cylinder 310 to drive the rejection cylinder 310 to move forward and push the ring to the reflow groove 400; for the ring in the third posture, the distance sensor 330 can detect that the height of the ring remains unchanged (the position of the ring with the opening facing left and right is a line segment extending left and right), and the ring directly moves right through the push plate 320. This allows the rejection device 300 to have the function of rejecting the ring in the second posture.
[0044] It is worth mentioning that the correction mechanism 500 preferably includes a hook plate 510 disposed on the upper side of the conveying device 100, and the distance between the lower end of the hook plate 510 and the conveying surface of the conveying device 100 is greater than the length of the ring and less than the outer diameter of the ring. Figure 2 , the ring in the first position can directly pass between the hook plate 510 and the upper conveying surface of the conveying device 100. When the upper right part of the ring in the third position abuts against the left side of the hook plate 510, the conveying device 100 drives the lower part of the ring to continue to move right, and the upper part of the ring turns left under the abutment of the hook plate 510, turning the ring 90 degrees to the first position and passing between the hook plate 510 and the upper conveying surface of the conveying device 100. Specifically, the left side of the hook plate 510 is preferably a rightward concave arc surface, which leaves more space for the ring to turn over, ensuring smooth turning of the ring.
[0045] Further, such as Figure 2 and Figure 4As shown, the correction mechanism 500 preferably also includes a screw 520 installed on the conveying device 100 and extending forward and backward through the middle of the hook plate 510, and two nuts 530 threadedly connected to the screw 520 and respectively used to abut against the front and rear sides of the hook plate 510; in fact, the middle of the hook plate 510 can be provided with a round through hole for the screw 520 to pass through, and by rotating the nut 530 to loosen the abutment with the hook plate 510, the front and rear position and rotation angle of the hook plate 510 can be adjusted to adapt to rings of different sizes within a certain range. In fact, the screw 520 can be fixed on the support frame of the conveying device 100.
[0046] In fact, the conveying device 100 preferably includes a base 110, a double-chain conveying mechanism 120 installed on the base 110, and two limit plates 130 correspondingly arranged on the front and rear sides of the chain mechanism and used to limit the ring, the middle of the rear limit plate 130 is provided with a first notch 131 for the push plate 320 to enter and exit, and the middle of the front limit plate 130 is provided with a second notch 132 connected to the entrance of the reflux groove 400. Since the ring with the opening shifted to the left and right direction is restricted from rolling forward and backward in front of the double-chain conveying mechanism 120 to change the opening to the left and right direction, it is ensured that the opening of the ring transferred to the conveying device 100 is in three positions: up and down, front and back, and left and right.
[0047] It should be noted that if Figure 5 As shown, the feeding device 200 preferably includes a raw material trough 210 for placing multiple rings and a lifting assembly 220 for transferring the rings in the raw material trough 210 to the conveyor belt in rows; the raw material trough 210 is provided with multiple first steps 211 that are gradually raised from the front to the back, and the lifting assembly 220 includes a lifting cylinder 221 and a lifting frame 222 installed at the lifting output end, and the lifting frame 222 is provided with multiple second steps 223 that are arranged one by one in front of the first step 211 and gradually raised from the front to the back, and the upper side of the first step 211 and the upper side of the second step 223 are inclined downward from the front to the back. The figure shows three first steps 211 and three second steps 223. The lifting cylinder 221 drives the lifting frame 222 to move downward so that the upper side of the second step 223 which is arranged one by one on the front side of the first step 211 is lower than the upper side of the first step 211 in front of it, and the ring moves from the first step 211 to the second step 223 on its rear side; the lifting cylinder 221 drives the lifting frame 222 to move upward so that the upper side of the second step 223 which is arranged one by one on the rear side of the first step 211 is lower than the upper side of the first step 211 in front of it, and the ring moves from the second step 223 to the first step 211 on its rear side or to the conveyor belt, thereby realizing the transfer of the rings in rows to the left part of the conveying device 100, thereby improving the efficiency of the feeding device 200 in transferring the rings to the conveying device 100.
[0048] In addition, the ring feeding device of the present invention preferably further includes a second photoelectric switch 700 disposed behind the correction mechanism 500 and used to detect the rings on the conveying device 100, and the second photoelectric switch 700 is in communication connection with the feeding device 200. When the rings gradually accumulate on the right side of the conveying device 100 until the left side of the accumulated second photoelectric switch 700, the second photoelectric switch 700 continues to detect the presence of the rings, and sends a signal to the feeding device 200 to stop the feeding device 200 from conveying the rings to the conveying device 100, thereby preventing the rings from accumulating too much on the conveying device 100 and avoiding the clogging of the conveying device.
[0049] It should be noted that the circular feeding equipment of the present invention is also preferably equipped with a controller such as a PLC to achieve communication connection and automatic operation between various electrical components.
[0050] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
