A pair of the lead screw nuts are respectively fixedly connected to the front end and the middle part of the push rod, so as to improve the symmetry and stability of the structure, improve the smoothness of transmission, optimize the force distribution of the structure, and extend the service life of the pushing mechanism.

[0011] Furthermore, the transmission mechanism is provided with a pair of transmission gears, and both of the pair of transmission gears are respectively meshed with a corresponding set of the driving gear and the driven gear, so as to further improve the stability of transmission.

[0012] Furthermore, it further includes a cracked part collection area, a wrinkled part collection area, a normal part collection area and an image acquisition device; A pair of the pushing mechanisms, the cracked part collection area and the wrinkled part collection area are respectively arranged on both sides of a conveyor belt for conveying stamping parts, and the cracked part collection area and the wrinkled part collection area are respectively arranged opposite to the push plates of a pair of the pushing mechanisms, and a pair of the push plates respectively serve as a cracked part push plate and a wrinkled part push plate; The normal part collection area is located at the end of the conveyor belt; the image acquisition device is in data communication with the controller, and its acquisition direction faces the conveyor belt.

[0013] A time-sharing control method for an energy-saving stamping part sorting device is used to control the above-mentioned energy-saving stamping part sorting device to perform sorting work, and includes the following processes: First step, confirm the states of the transmission mechanism (4) and the pushing mechanism (5), so that a pair of transmission gears (42) are in a state separated from the driving gear (22) and the driven gear (51), and a pair of push plates (56) are in a retracted state; Subsequently, set the working parameters of the stamping part sorting device and the conveyor belt to meet Equation 1 below: (Equation 1); Wherein, L1 is the distance between the rupture part push plate and the wrinkling part push plate, L2 is the width of the conveyor belt, V is the speed of the conveyor belt, V1 is the forward stroke speed of the driving mechanism (2) driving the push plate (56), V2 is the return stroke speed of the driving mechanism (2) driving the push plate (56), t1 is the time required for the transmission gear (42) to move from the initial position to engage with the driving gear (22) and the driven gear (51), and t2 is the time required for the transmission gear (42) to move away from the driving gear (22) and the driven gear (51) and return to the reset position; When the stamping part sorting device is provided with an auxiliary driving mechanism (3), the working parameters of the auxiliary driving mechanism (3) should also be set to meet Equation 2 below: (Equation 2); Wherein, V3 is the forward stroke speed of the auxiliary driving mechanism (3) driving the push plate (56), and V4 is the return stroke speed of the auxiliary driving mechanism (3) driving the push plate (56); Second step, set the spacing I between the stamping parts conveyed by the conveyor belt, and make I meet Equation 3 below: I≥L1 (Equation 3); Make adjacent stamping parts enter the sorting with I as the spacing; Third step, place each stamping part on the conveyor belt and convey it forward under the action of the conveyor belt. Let the two stamping parts about to enter between the pushing mechanism (5) and the rupture part collection area (6) or the wrinkling part collection area (7) be stamping part A and stamping part B respectively. The image acquisition device acquires the images of stamping part A and stamping part B and transmits them to the controller, and the controller judges the value of I: If I = L1, then go to the fourth step; If , then go to the fifth step; Otherwise, , go to the sixth step; Fourth step, the controller judges the type of the stamping part: If either the stamping part A or the stamping part B is a cracked part and the other is a wrinkled part, and the conveying order of the damaged part and the wrinkled part corresponds to the setting position order of the cracked part push plate and the wrinkled part push plate, the driving mechanism (2) starts with a high power that can at least drive the two pushing mechanisms (5) to work simultaneously. When the stamping part A and the stamping part B are respectively conveyed between the two pushing mechanisms (5) and the cracked part collection area (6) or the wrinkled part collection area (7), the driving mechanism (2) drives the cracked part push plate and the wrinkled part push plate to just extend, push the cracked part and the wrinkled part from the conveyor belt into the cracked part collection area (6) and the wrinkled part collection area (7), and then reset; At the same time, after the stamping part A and the stamping part B are both conveyed into the area between the pushing mechanism (5) and the cracked part collection area (6) or the wrinkled part collection area (7), the third step is carried out again until the stamping part sorting device stops; Otherwise, go to the sixth step; Step 5, the controller judges the type of the stamping part: If either the stamping part A or the stamping part B is a damaged part and the other is a wrinkled part, and the conveying order of the damaged part and the wrinkled part corresponds to the setting position order of the cracked part push plate and the wrinkled part push plate, the driving mechanism (2) starts with a low power that can at least drive one pushing mechanism (5) to work. When the stamping part A is conveyed between the subsequent pushing mechanism (5) along the conveying direction and the cracked part collection area (6) or the wrinkled part collection area (7), the driving mechanism (2) drives the cracked part push plate or the wrinkled part push plate to just extend, push the stamping part A from the conveyor belt into the cracked part collection area (6) or the wrinkled part collection area (7), and then reset; During the process from the driving mechanism (2) driving the cracked part push plate or the wrinkled part push plate to start extending to the cracked part push plate or the wrinkled part push plate retracting and resetting, the stamping part B is conveyed between the previous pushing mechanism (5) along the conveying direction and the wrinkled part collection area (7) or the cracked part collection area (6). At this time, the auxiliary driving mechanism (3) drives the wrinkled part push plate or the cracked part push plate to just extend, push the stamping part B from the conveyor belt into the wrinkled part collection area (7) or the cracked part collection area (6), and then reset; At the same time, after the stamping part A and the stamping part B are both conveyed into the area between the pushing mechanism (5) and the cracked part collection area (6) or the wrinkled part collection area (7), the third step is carried out again until the stamping part sorting device stops; Otherwise, go to the sixth step; Step 6, the controller judges the type of the stamping part: If both the stamping part A and the stamping part B are normal parts, the two pushing mechanisms (5) remain in the initial state until both the stamping part A and the stamping part B are conveyed into the area between the pushing mechanism (5) and the cracked part collection area (6) or the wrinkled part collection area (7), and the third step is carried out again until the stamping part sorting device stops; Otherwise, if at least one of the stamped parts A and B is a cracked part or a wrinkled part, the driving mechanism (2) starts with a low power that can at least drive one of the pushing mechanisms (5) to work. When at least one wrinkled part or cracked part is conveyed between the pushing mechanism (5) and the cracked part collection area (6) or the wrinkled part collection area (7), the cracked part push plate or the wrinkled part push plate just extends out, pushes the cracked part or the wrinkled part from the conveyor belt into the cracked part collection area (6) and the wrinkled part collection area (7), and then resets; Meanwhile, after both the stamped part A and the stamped part B are conveyed between the pushing mechanism (5) and the cracked part collection area (6) or the wrinkled part collection area (7), the third step is performed again until the stamped part sorting device stops.

[0014] In the above-mentioned third and fourth steps, the method for the controller to judge the type of the stamped part according to the image collected by the image acquisition device can be specifically referred to "Research on the Defect Recognition Method of Stamped Parts Based on Machine Vision" (Zhao Jiayi. Research on the Defect Recognition Method of Stamped Parts Based on Machine Vision [D], 2020.). The present invention provides an energy-saving stamped part sorting device and a time-sharing control method for its driving unit, and has the following beneficial effects: 1. The stamped part sorting device of the present invention uses the same driving mechanism to drive multiple pushing mechanisms through multiple transmission mechanisms, which can effectively improve the utilization rate of the driving mechanism, reduce the equipment cost, and reduce the waste of energy and the loss of resources.

[0015] 2. The present invention improves the compactness of the structure of the stamped part sorting device, reduces the occupied area of the stamped part sorting device, and is beneficial to the optimization of the production site layout.

[0016] 3. The time-sharing control method of the present invention rationally utilizes the energy of the driving mechanism by driving the two push rod devices separately or simultaneously and correspondingly adjusting the output power of the driving mechanism, so as to further improve the energy utilization rate and has the advantage of energy saving.

[0017] 4. The present invention can be equipped with an auxiliary driving mechanism with a power much smaller than that of the driving mechanism to cooperate with the driving mechanism to work, so as to drive a pair of pushing mechanisms to perform the pushing and sorting work at different but close time points respectively. On the premise of maintaining relatively low energy consumption, the adaptability of the sorting device to special working conditions is further expanded. Brief Description of the Drawings

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] An energy-saving stamping part sorting device, as Figures 1 to 4 shown, its structural relationship is as follows: It includes a frame 1, a driving mechanism 2, an auxiliary driving mechanism 3, a pair of transmission mechanisms 4 and a pair of pushing mechanisms 5, and is equipped with a conveyor belt, a cracked part collection area 6, a wrinkled part collection area 7, a normal part collection area 8 and an image acquisition device.

[0022] The cracked part collection area 6 and the wrinkled part collection area 7 are arranged on one side of the conveyor belt and are arranged in sequence along the conveying direction of the conveyor belt. A pair of pushing mechanisms 5 are arranged on the other side of the conveyor belt and are respectively arranged opposite to the cracked part collection area 6 and the wrinkled part collection area 7. A pair of push plates 56 serve as the cracked part push plate and the wrinkled part push plate respectively; the normal part collection area 8 is located at the end of the conveyor belt; the image acquisition device is in data communication with the controller, and its acquisition direction faces the conveyor belt.

[0023] The driving mechanism 2 includes a driving motor 21 and a driving gear 22. The driving gear 22 serves as the output end of the driving mechanism 2 and is shaft-connected to the output shaft of the driving motor 21.

[0024] The auxiliary driving mechanism 3 includes an auxiliary driving motor 31 and an auxiliary driving gear 32. The auxiliary driving gear 32 is shaft-connected to the output shaft of the auxiliary driving motor 31 and meshes with the driven gear 51 of the pushing mechanism 5 (the previous pushing mechanism 5 along the conveying direction) opposite to the cracked part collection area 6.

[0025] The transmission mechanism 4 includes a pair of magnetic-coupled rodless cylinders and a pair of transmission gears 42. The magnetic-coupled rodless cylinders are installed on the frame 1, and the output ends of the pair of magnetic-coupled rodless cylinders are respectively fixedly installed with the pair of transmission gears 42 to drive the pair of transmission gears 42 to act synchronously.

[0026] The pushing mechanism 5 includes a driven gear 51, a lead screw shaft 52, a pair of lead screw nuts 53, a lead screw guide rail 54, a pair of push rods 55 and a push plate 56; the lead screw nuts 53 are arranged in pairs along the axial direction of the lead screw shaft 52, are threadedly fitted and installed on the lead screw shaft 52, and are slidably fitted and installed with the lead screw guide rail 54; the push rods 55 are arranged in pairs on both sides of the lead screw shaft 52, and the push plate 56 is fixedly installed with the lead screw nuts 53 through the push rods 55, and the pair of lead screw nuts 53 are respectively fixedly connected to the front end and the middle part of the push rod 55; the lead screw shaft 52 and the driven gear 51 serving as the input end of the pushing mechanism 5 are coaxially fixedly connected.

[0027] When the above-mentioned stamping part sorting device works, one action of the driving mechanism 2 to drive a pushing mechanism 5 includes the following process: First step, the magnetic-coupled rodless cylinder drives the transmission gear 42 to move, so that the transmission gear 42 meshes between the driving gear 22 and the driven gear 51; Second step, the driving motor 21 drives the driving gear 22 to rotate forward, and the rotation is sequentially transmitted through the driving gear 22, the transmission gear 42 and the driven gear 51 to the lead screw shaft 52, so that the lead screw nut 53 drives the push plate 56 to extend out through the push rod 55 under the guiding and limiting action of the lead screw guide rail 54; Third step, the driving motor 21 drives the driving gear 22 to rotate reversely, and the rotation is sequentially transmitted through the driving gear 22, the transmission gear 42 and the driven gear 51 to the lead screw shaft 52, so that the lead screw nut 53 drives the push plate 56 to retract and reset through the push rod 55 under the guiding and limiting action of the lead screw guide rail 54; Fourth step, the magnetic-coupled rodless cylinder drives the transmission gear 42 to move, so that the transmission gear 42 disengages and resets from between the driving gear 22 and the driven gear 51.

[0028] When the above-mentioned stamping part sorting device works, one action of the auxiliary driving mechanism 3 to drive the previous pushing mechanism 5 along the conveying direction includes the following process: First step, the auxiliary driving motor 31 drives the driven gear 51 to rotate forward, which is sequentially transmitted to the lead screw shaft 52, so that the lead screw nut 53 drives the push plate 56 to extend out through the push rod 55 under the guiding and limiting action of the lead screw guide rail 54; Second step, the auxiliary driving motor 31 drives the driven gear 51 to rotate reversely, which is sequentially transmitted to the lead screw shaft 52, so that the lead screw nut 53 drives the push plate 56 to retract and reset through the push rod 55 under the guiding and limiting action of the lead screw guide rail 54.

[0029] During the working process of the above stamping part sorting device, when the push plate 56 of the pushing mechanism 5 is extended by the driving mechanism 2 through the transmission mechanism 4, the time required for the magnetic coupling rodless cylinder to drive the transmission gear 42 to engage between the driving gear 22 and the driven gear 51 is t1, and the driven gear 51 rotates at a speed of n 13 Rotation makes the pushing speed of the push rod 56 be V1, then V1 satisfies: V1 = n 13 ×Ph; where Ph is the lead of the lead screw shaft 52.

[0030] When the driving mechanism 2 drives the push plate 56 of the pushing mechanism 5 to retract through the transmission mechanism 4, the driven gear 51 rotates at a speed of n 23 Rotation, the time required for the magnetic coupling rodless cylinder to drive the transmission gear 42 to disengage from between the driving gear 22 and the driven gear 51 and reset is t2. Let the return speed of the push rod 56 be V2, then V2 satisfies: V2 = n 23 ×Ph; For each pushing mechanism 5, when its push plate 56 extends once under the drive of the driving mechanism 2, to ensure that before the next stamping part reaches its working position, the push plate 56 has completed retraction and reset and can perform the next extension action, then formula one and formula three should be satisfied.

[0031] In addition, when I = L1, the driving mechanism 2 can drive the push plates 56 of the two pushing mechanisms 5 to extend synchronously at the same time, and push two stamping parts into the cracked part collection area 6 and the wrinkled part collection area 7 respectively, and the driving mechanism 2 can be used alone to drive the pushing mechanism 5. And when At this time, when the latter pushing mechanism 5 along the conveying direction pushes the first stamping part and has not completed reset, the second stamping part has already moved to the previous pushing mechanism 5 along the conveying direction. The driving mechanism 2 cannot drive the non-synchronous actions of the two pushing mechanisms 5 at the same time, so the auxiliary driving mechanism 3 needs to be used to drive the previous pushing mechanism 5 along the conveying direction.

[0032] During the working process of the above stamping part sorting device, when the auxiliary driving mechanism 3 drives the push plate 56 of the pushing mechanism 5 to extend, the driven gear 51 rotates at a speed of n 33 Rotation makes the pushing speed of the push rod 56 be V3, then V3 satisfies: V3 = n 33 ×Ph; When the auxiliary driving mechanism 3 drives the push plate 56 of the pushing mechanism 5 to retract, the driven gear 51 rotates at a speed of n 43 Rotation makes the return speed of the push rod 56 be V4, then V4 satisfies: V4 = n 43 ×Ph; For the previous pushing mechanism 5 along the conveying direction, after its push plate 56 extends once under the drive of the auxiliary drive mechanism 3, in order to ensure that before the next stamping part reaches its working position, the push plate 56 has completed the retraction and reset and can perform the next extension action, the second formula and the third formula should be satisfied.

[0033] A time-sharing control method for an energy-saving stamping part sorting device, which is used to control the above-mentioned energy-saving stamping part sorting device to perform the sorting work of stamping parts, including the following processes: In the first step, confirm the states of the transmission mechanism 4 and the pushing mechanism 5, so that a pair of transmission gears 42 are in a state separated from the driving gear 22 and the driven gear 51, and a pair of push plates 56 are in a retracted state; Subsequently, set the working parameters of the stamping part sorting device and the conveyor belt to satisfy the following formula one: (Formula one); Among them, L1 is the distance between the rupture part push plate and the wrinkling part push plate, L2 is the width of the conveyor belt, V is the speed of the conveyor belt, V1 is the pushing speed of the drive mechanism 2 driving the push plate 56, V2 is the return speed of the drive mechanism 2 driving the push plate 56, t1 is the time required for the transmission gear 42 to move from the initial position to engage with the driving gear 22 and the driven gear 51, and t2 is the time required for the transmission gear 42 to move away from the driving gear 22 and the driven gear 51 to reset; When the stamping part sorting device is provided with an auxiliary drive mechanism 3, the working parameters of the auxiliary drive mechanism 3 should also be set to satisfy the following formula two: (Formula two); Among them, V3 is the pushing speed of the auxiliary drive mechanism 3 driving the push plate 56, and V4 is the return speed of the auxiliary drive mechanism 3 driving the push plate 56; In the second step, set the spacing I of the conveyor belt for conveying stamping parts, and make I satisfy the following formula three: I≥L1 (Formula three); Make adjacent stamping parts enter the sorting with I as the spacing; In the third step, place each stamping part on the conveyor belt and convey it forward under the action of the conveyor belt. Let the two stamping parts about to enter between the pushing mechanism 5 and the rupture part collection area 6 or the wrinkling part collection area 7 be stamping part A and stamping part B respectively. The image acquisition device acquires the images of stamping part A and stamping part B and transmits them to the controller. The controller judges the value of I: If I = L1, then proceed to the fourth step; If , then proceed to the fifth step; Otherwise, , proceed to the sixth step; In the fourth step, the controller judges the type of the stamping part: If any one of the stamping parts A and B is a damaged part and the other is a wrinkled part, and the conveying order of the damaged part and the wrinkled part corresponds to the setting position order of the broken part push plate and the wrinkled part push plate, the driving mechanism 2 starts with a high power that can at least drive the two pushing mechanisms 5 to work simultaneously. When the stamping parts A and B are respectively conveyed between the two pushing mechanisms 5 and the broken part collection area 6 or the wrinkled part collection area 7, the driving mechanism 2 drives the broken part push plate and the wrinkled part push plate to just extend out, push the broken part and the wrinkled part from the conveyor belt into the broken part collection area 6 and the wrinkled part collection area 7, and then reset; At the same time, after both the stamping parts A and B are conveyed into the area between the pushing mechanism 5 and the broken part collection area 6 or the wrinkled part collection area 7, the third step is carried out again until the stamping part sorting device stops; Otherwise, go to the sixth step; Step 5, the controller judges the type of the stamping part: If any one of the stamping parts A and B is a damaged part and the other is a wrinkled part, and the conveying order of the damaged part and the wrinkled part corresponds to the setting position order of the broken part push plate and the wrinkled part push plate, the driving mechanism 2 starts with a low power that can at least drive one pushing mechanism 5 to work. When the stamping part A is conveyed between the subsequent pushing mechanism 5 along the conveying direction and the broken part collection area 6 or the wrinkled part collection area 7, the driving mechanism 2 drives the broken part push plate or the wrinkled part push plate to just extend out, push the stamping part A from the conveyor belt into the broken part collection area 6 or the wrinkled part collection area 7, and then reset; During the process from the driving mechanism 2 driving the broken part push plate or the wrinkled part push plate to start extending to the broken part push plate or the wrinkled part push plate retracting and resetting, the stamping part B is conveyed between the previous pushing mechanism 5 along the conveying direction and the wrinkled part collection area 7 or the broken part collection area 6. At this time, the auxiliary driving mechanism 3 drives the wrinkled part push plate or the broken part push plate to just extend out, push the stamping part B from the conveyor belt into the wrinkled part collection area 7 or the broken part collection area 6, and then reset; At the same time, after both the stamping parts A and B are conveyed into the area between the pushing mechanism 5 and the broken part collection area 6 or the wrinkled part collection area 7, the third step is carried out again until the stamping part sorting device stops; Otherwise, go to the sixth step; Step 6, the controller judges the type of the stamping part: If both the stamping parts A and B are normal parts, the two pushing mechanisms 5 remain in the initial state until both the stamping parts A and B are conveyed into the area between the pushing mechanism 5 and the broken part collection area 6 or the wrinkled part collection area 7, and the third step is carried out again until the stamping part sorting device stops; Otherwise, if at least one of the stamped parts A and B is a cracked part or a wrinkled part, the driving mechanism 2 starts with a low power that can at least drive one of the pushing mechanisms 5 to work. When at least one of the wrinkled parts or cracked parts is conveyed between the pushing mechanism 5 and the cracked part collection area 6 or the wrinkled part collection area 7, the cracked part push plate or the wrinkled part push plate just extends out, pushes the cracked part or the wrinkled part from the conveyor belt into the cracked part collection area 6 and the wrinkled part collection area 7, and then resets; Meanwhile, after both the stamped part A and the stamped part B are conveyed between the pushing mechanism 5 and the cracked part collection area 6 or the wrinkled part collection area 7, the third step is carried out again until the stamped part sorting device stops.
