Description

Technical Field

[0001] This utility model belongs to the technical field of piston production equipment, and in particular relates to a piston sorting and feeding device. Background Technology

[0002] Pistons are a core component in the mechanical field, playing a crucial role in equipment such as brake calipers and hydraulic valve groups due to their core functions of sealing and force transmission.

[0003] For traditional caliper pistons, aluminum alloy is usually used as the blank material and is plastically formed into a blank with an open end and a closed end through cold heading process. Due to the limited precision of cold heading, subsequent roughing and finishing are required. In the process of feeding the cold heading blank into the roughing or finishing process, the open end and closed end of the piston must be accurately distinguished. For example, the closed end is used as the positioning reference for roughing. If the axial orientation is confused, it will lead to positioning deviation and affect product quality.

[0004] Traditional methods mostly rely on manual sorting and feeding, requiring manual identification and adjustment of the orientation of each item. This not only incurs continuous labor costs but also results in low sorting efficiency and is prone to misjudgment of orientation due to human fatigue, affecting the yield of subsequent processing. Some production lines use a "robotic arm + vision recognition system" to achieve automatic orientation identification and directional gripping, but the procurement and maintenance costs of the entire system are high. Therefore, there is an urgent need for a low-cost piston sorting and feeding device that can ensure the differentiation and adjustment of orientation before piston feeding. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a piston sorting and feeding device that achieves low-cost investment while ensuring the effectiveness of distinguishing and adjusting the orientation of the piston before feeding.

[0006] In view of this, the present invention provides a piston sorting and feeding device, comprising: The frame is equipped with a conveyor belt for conveying pistons; The sorting mechanism is mounted on the frame and is used to detect the axial direction of the pistons on the conveyor belt and, based on the detection feedback, adjusts them to a uniform axial orientation by rotation. The feeding mechanism is mounted on the frame and located below the sorting mechanism. It is used to rotate and adjust the piston to move horizontally out, and then the material is picked up by a robotic arm.

[0007] In the above technical solution, the sorting mechanism further includes: A detection component, installed at the end of the conveyor belt, is used to detect the axial orientation of the piston; The rotating assembly, mounted on the frame, receives the piston on the conveyor belt and drives the piston to rotate forward or backward according to feedback from the detection assembly to adjust its axial orientation.

[0008] In the above technical solution, further: The detection assembly includes a baffle mounted above the conveyor belt and an infrared sensor mounted on the side of the conveyor belt, with a detection unit mounted on the baffle. The frame is equipped with a first drive cylinder, which is used to drive a baffle to intercept and release the movement of the piston.

[0009] In the above technical solution, the detection unit further includes: The second drive cylinder is mounted on the baffle, and the baffle has a through hole corresponding to the output end of the second drive cylinder; A gravity sensor is installed at the output end of the second drive cylinder and is pushed by the second drive cylinder to pass through the through hole. It is used to detect whether the side of the piston near the baffle is an open end or a closed end.

[0010] In the above technical solution, further: The output end of the second drive cylinder is provided with an elastic cover, and along the driving direction of the second drive cylinder, an elastic block is provided between the inner wall of the elastic cover and the gravity sensor.

[0011] In the above technical solution, further: The frame also includes a fixing block installed at the end of the conveyor belt, and the fixing block has a spherical cavity and a discharge port that communicates with the spherical cavity vertically at the bottom; The rotating assembly includes a sphere rotatably connected to a spherical chamber and a first driving device for driving the sphere to rotate along a vertical plane. A through hole is provided in the sphere through its center, and a first chamfer is provided on the side of the through hole near the conveyor belt. The first driving device is used to drive the ball to rotate so that the through hole aligns with the discharge port.

[0012] In the above technical solution, further: The discharge port is equipped with a guide cylinder, and the end of the guide cylinder near the spherical chamber has a second chamfer.

[0013] In the above technical solution, the feeding mechanism further includes: The movable block is slidably connected to the frame, and a countersunk hole is provided in the movable block, with a third chamfer at the top of the countersunk hole; The second drive unit is mounted on the frame and is used to drive the moving block to move into or out of the sorting mechanism.

[0014] The beneficial effects of this utility model are as follows: 1. By employing a sorting mechanism, the axial direction of the piston is detected, and based on the detection, it is adjusted by rotation to maintain a uniform axial orientation. Subsequently, a feeding mechanism moves the piston out for the robotic arm to grasp. This avoids the labor costs, low efficiency, and error-prone nature of manual sorting, as well as the need to use a robotic arm in conjunction with a vision recognition system for sorting, thereby reducing equipment investment costs and subsequent maintenance costs.

[0015] 2. By using a second drive cylinder to push a gravity sensor to detect and distinguish between the open and closed ends of the piston, the investment cost is effectively reduced. After distinguishing between the open and closed ends, the piston can be bidirectionally adjusted by guiding it into the rotating assembly for forward and reverse rotation, thereby facilitating the conversion of the piston's axial orientation. This not only reduces costs but also effectively ensures conversion efficiency. 3. The vertically set discharge port and the moving block with the countersunk hole are used. After the piston is driven to rotate by the rotating component, when the through hole corresponds to the discharge port, the piston will fall due to its own weight and fall into the countersunk hole. The second driving device drives the moving block to move out from under the sorting mechanism. The structure is simple, the investment cost is low, and the convenience is high, which effectively ensures production efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0018] Example 1: This embodiment provides a piston sorting and feeding device, including: The frame 1 is equipped with a conveyor belt 2 for conveying the piston 3; The sorting mechanism is mounted on the frame 1 and is used to detect the axial direction of the piston 3 on the conveyor belt 2 and, based on the detection feedback, adjust it to a uniform axial orientation by rotation. The feeding mechanism 4 is mounted on the frame 1 and located below the sorting mechanism. It is used to rotate the adjusted piston 3 to move horizontally out, and then grab it by the robot arm. The specific structures of the conveyor belt 2 and the robot are existing mature technologies, which are known to those skilled in the art from traditional conveyor belts 2 and robots, and will not be elaborated here.

[0019] As can be seen from this embodiment, by using a sorting mechanism to detect the axial direction of piston 3, and then adjusting it by rotation to maintain a uniform axial orientation, the feeding mechanism 4 moves piston 3 out for the robotic arm to grasp. This avoids the labor costs, low efficiency and error-proneness of manual sorting, and avoids the use of robotic arms in conjunction with a vision recognition system for sorting, thereby reducing the investment cost of equipment and the subsequent maintenance cost. Furthermore, after the axial orientation of piston 3 is adjusted by the sorting mechanism, it is moved out by the feeding mechanism 4 and then picked up by the robot. The robot used here has lower technical requirements and lower investment costs compared to the robot used in some production lines that uses "robot + vision recognition system" to achieve end-to-end automatic recognition and directional picking.

[0020] Example 2: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the sorting mechanism includes: The detection component 5 is installed at the end of the conveyor belt 2 and is used to detect the orientation of the piston 3 along the axial direction; The rotating assembly 6 is mounted on the frame 1 and is used to receive the piston 3 on the conveyor belt 2. Based on the feedback from the detection assembly 5, it drives the piston 3 to rotate forward or backward to adjust the axial orientation.

[0021] As can be seen from this embodiment, by using the second drive cylinder 70 to push the gravity sensor 72 to detect and distinguish the open end or closed end of the piston 3, the investment cost is effectively reduced. Furthermore, after distinguishing the open end and the closed end, the piston 3 is guided into the rotating assembly 6 for bidirectional adjustment in the forward and reverse directions, thereby conveniently changing the axial orientation of the piston 3. This not only reduces costs but also effectively ensures conversion efficiency. Example 3: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The detection component 5 includes a baffle 50 installed above the conveyor belt 2 and an infrared sensor 51 installed on the side of the conveyor belt 2, and a detection unit 7 is installed on the baffle 50. The frame 1 is equipped with a first drive cylinder 52, which is used to drive the baffle 50 to intercept and release the movement of the piston 3. Meanwhile, the specific structure of the infrared sensor 51 is a mature existing technology, a routine detection operation used in traditional conveyor production lines for the supply of individual products, and is known to those skilled in the art from traditional conveyor production lines, so it will not be elaborated here. Furthermore, the first drive cylinder 52 can be a pneumatic cylinder.

[0022] As can be seen from this embodiment, by using the baffle 50 and the infrared sensor 51, invalid detection is avoided. At the same time, the detection unit 7 is set on the baffle 50, which facilitates the detection according to the different structural characteristics of the open end and the closed end, effectively ensuring the accuracy of the detection. The first drive cylinder 52 facilitates the removal of the baffle 50, ensuring the continued delivery of the piston 3 after the axial orientation detection.

[0023] Example 4: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features, wherein the detection unit 7 includes: The second drive cylinder 70 is mounted on the baffle 50, and the baffle 50 has a through hole 71 corresponding to the output end of the second drive cylinder 70. Gravity sensor 72 is installed at the output end of the second drive cylinder 70 and is pushed by the second drive cylinder 70 to pass through the through hole 71, used to detect whether the side of the piston 3 near the baffle 50 is an open end or a closed end; The second drive cylinder 70 can be a pneumatic cylinder, and its specific structure with the gravity sensor 72 is a mature existing technology, which is known to those skilled in the art from traditional pneumatic cylinders and gravity sensors 72, and will not be described in detail here.

[0024] As can be seen from this embodiment, the gravity sensor 72 is pushed through the through hole 71 and close to the piston 3 by the second drive cylinder 70. Based on the obvious difference in the triggering of the gravity sensor 72 by the open end and the closed end of the piston 3, it is possible to distinguish whether the end of the piston 3 close to the baffle 50 is the open end or the closed end. In combination with the forward and reverse rotation of the subsequent rotating component 6, it is easy to keep the axial orientation of the piston 3 uniform, which is convenient for the subsequent direct clamping and feeding by the robot without further adjustment.

[0025] Example 5: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The output end of the second drive cylinder 70 is provided with an elastic cover 73, and along the driving direction of the second drive cylinder 70, an elastic block 74 is provided between the inner wall of the elastic cover 73 and the gravity sensor 72. Both the elastic cover 73 and the elastic block 74 can be made of rubber.

[0026] As can be seen from this embodiment, the elastic cover 73 can provide a certain degree of protection for the gravity sensor 72, and the elastic block 74 can provide a certain buffering effect when the second drive cylinder 70 pushes the gravity sensor 72 to contact the piston 3. Furthermore, the force when the gravity sensor 72 comes into contact with the closed end is smoothly transmitted to the gravity sensor 72 by the elastic block 74, avoiding rigid contact and effectively ensuring the service life of the gravity sensor 72.

[0027] Example 6: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The frame 1 also includes a fixing block 8 installed at the end of the conveyor belt 2, and the fixing block 8 has a spherical cavity 9 and a discharge port 10 vertically opened at the bottom that communicates with the spherical cavity 9; The rotating assembly 6 includes a sphere 60 rotatably connected to the spherical chamber 9 and a first driving device 61 for driving the sphere 60 to rotate along the vertical plane. A through hole 62 is provided in the sphere 60 through the center of the sphere, and a first chamfer 63 is provided on the side of the through hole 62 near the conveyor belt 2. The first driving device 61 is used to drive the ball 60 to rotate so that the through hole 62 corresponds to the discharge port 10. Meanwhile, the first drive device 61 can use a motor and an indexer. The specific structure of these devices is based on existing mature technologies, which are known to those skilled in the art from traditional motors and indexers, and will not be elaborated here.

[0028] As can be seen from this embodiment, by opening the spherical chamber 9 and opening the discharge port 10 at its bottom, and cooperating with the rotation of the ball 60, the two ends of the through hole 62 in the ball 60 correspond to the discharge port 10 when rotating forward or backward, respectively. This makes it easier for the two ends of the piston 3 that is guided into the through hole 62 to correspond to the discharge port 10 when rotating forward or backward, thereby making it easier to control the axial orientation of the piston 3 when feeding. Moreover, the structure is simple and the manufacturing cost is low. The opening of the first chamfer 63 facilitates the piston 3 to enter the through hole 62. Preferably, the conveyor belt 2 can be tilted, and the corresponding through hole 62 can be tilted, keeping the through hole 62 parallel to the conveying direction of the conveyor belt 2. The tilt angle can be 5°-10°, which makes it easier to guide the piston 3 into the through hole 62. Furthermore, the discharge port 10 is vertically oriented, which ensures the stability of the axial orientation of the piston 3 after it comes out of the discharge port 10, and prevents it from tipping over.

[0029] Example 7: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The discharge port 10 is equipped with a guide cylinder 11, and the end of the guide cylinder 11 near the spherical chamber 9 is provided with a second chamfer 12.

[0030] As can be seen from this embodiment, the stability and guiding effect of the piston 3 when it falls are further improved by setting the guide cylinder 11, and the opening of the second chamfer 12 makes it easier for the piston 3 to enter the guide cylinder 11 from the discharge port 10, thus avoiding jamming when the piston 3 falls.

[0031] Example 8: This embodiment provides a piston sorting and feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the feeding mechanism 4 includes: The movable block 40 is slidably connected to the frame 1, and a countersunk hole 41 is provided in the movable block 40, and a third chamfer 42 is provided at the top of the countersunk hole 41. The second drive unit 43 is mounted on the frame 1 and is used to drive the moving block 40 to move into or out of the sorting mechanism. The second drive device 43 can be a motor and a lead screw transmission assembly, and a slider and a slide rail are set between the moving block 40 and the frame 1. The specific structure is a mature existing technology, which can be known to those skilled in the art from traditional motors, lead screw transmission assemblies, sliders and slide rails, and will not be described in detail here.

[0032] As can be seen from this embodiment, the second driving device 43 drives the moving block 40 to reciprocate between the sorting mechanism and the robot gripping station, ensuring that the piston 3 is moved out from under the sorting mechanism, which is convenient for the robot to grip, effectively improving convenience, and the structure is simple and the investment cost is low.

[0033] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
