Description

Technical Field

[0001] This application relates to the technical field of automotive handle rotor detection equipment, and in particular to a detection and classification device for automotive handle rotors. Background Art

[0002] An automotive handle rotor is essentially a damper installed at the rotational connection position of the handle. The role of the rotor is to absorb energy, reduce the maximum value of the frequency response, and then slowly release the energy, thereby eliminating sudden energy shocks. For example, when the automotive handle is not installed with a rotor, after taking out the handle and releasing it, the handle will retract very rigidly with a "bang"; after the automotive handle is installed with a rotor, after taking out the handle and releasing it, the handle will retract slowly and gracefully.

[0003] An existing automotive handle rotor is as shown in Figure 1 and Figure 2 and includes a housing, a core body, and a cover body. The outer shape of the housing is a cylinder. A through hole for the handle rotating shaft to pass through is axially penetrated through the center of the housing. And an installation groove for inserting and installing the core body is opened on the circumferential side of the through hole on the housing. The installation groove penetrates one end in the axial direction of the housing. The outer side of the housing has a rib for clamping with the handle. The core body is an overall hollow cylinder structure. Before the core body is installed in the installation groove, damping oil is applied to the installation groove in the housing. After the core body is installed in the installation groove, the core body is rotationally connected with the housing along the axis of the housing. And one end of the core body close to the opening of the installation groove of the housing has two convex blocks, and the two convex blocks are located at both ends in the same diameter direction of the core body. The cover body is an overall disc structure. One end face of the cover body has two mating grooves, and a convex portion is provided at the corresponding position of the mating groove on the other end face of the cover body. After the cover body is closed at one end of the housing close to the opening of the installation groove, the two convex blocks of the core body are respectively inserted into the two mating grooves.

[0004] Before the rotor is used, it is necessary to detect the magnitude of its damping force, and judge whether its damping force meets the product requirements through the detection results, and screen out and eliminate unqualified rotors. The traditional process of detecting the damping force of the rotor usually requires operators to hold the detection equipment and detect the rotors one by one, with low automation and troublesome operation. Therefore, there is an urgent need for a device that is convenient for detecting and classifying the damping force of the rotor. Summary of the Invention

[0005] In order to improve the problem that the process of detecting and classifying the damping force of the rotor is not convenient enough, this application provides a detection and classification device for automotive handle rotors.

[0007] A detection and classification device for automobile handle rotors, comprising a feeding mechanism for feeding, a detection mechanism for detecting the damping force of the rotor, a classification mechanism for classifying the rotor according to the detection results, and a transportation mechanism for carrying the rotor to move, wherein the feeding mechanism, the detection mechanism and the classification mechanism are all located on the circumferential side of the transportation mechanism, the transportation mechanism comprises a rotating disk and a first driving member for driving the rotating disk to rotate, the rotating axis of the rotating disk is vertically arranged, and a circular array on the rotating disk has four positioning seats for fixing the rotor, the feeding mechanism comprises a vibrating disk and a feeding track, one end of the feeding track is fixedly connected to the vibrating disk, the classification mechanism comprises an elimination component for allowing unqualified products to leave the rotating disk and a retention component for allowing qualified products to leave the rotating disk, the feeding track, the detection mechanism, the elimination component and the retention component are arranged in sequence on the circumferential side of the rotating disk and are also distributed in a circular array, the first driving member drives the rotating disk to rotate periodically by 90°, and after each rotation of the rotating disk, the end of the feeding track away from the vibrating disk leads to a positioning seat.

[0008] By adopting the above technical scheme, a number of rotors are moved to the positioning seat for positioning under the predetermined state under the action of the feeding mechanism, the detection mechanism detects the damping force of the rotor on the mounting seat, the classification mechanism classifies the rotors according to the detection results, and the rotating disk rotates to make the rotors pass through different processes in sequence. The cooperation of various mechanisms makes the detection and classification device more automated, thereby making the detection and classification process of automobile handle rotors more convenient and efficient.

[0009] Optionally, the positioning seat is provided with a positioning groove for the rotor to enter and a clearance groove adapted to the convex strip on the rotor, one end of the clearance groove is communicated with the positioning groove, and the other end of the clearance groove passes through the top of the positioning seat, and guide members are provided on both sides of the feeding track, and there is a clearance space for the convex strip on the rotor to pass through between the ends of the two guide members away from the feeding track, and after each rotation of the rotating disk, the clearance space is aligned with the clearance groove in a straight line direction and is communicated with it.

[0010] By adopting the above technical solution, the rotor can maintain a predetermined position state unchanged during the movement on the loading track, thereby facilitating the rotor to be moved from the loading track to the positioning seat for fixation, and reducing the probability that the rotor's position state deviates during the movement and cannot enter the positioning groove and be fixed on the positioning seat.

[0011] Optionally, the end of the guide member away from the rotating disk has a chamfer, so that the space between the ends of the two guide members away from the rotating disk is larger.

[0012] By adopting the above technical solution, the rotor moved out from the vibration plate can be guided to facilitate the rotor to smoothly enter the feeding track, and the position state of the moving rotor can be adjusted at the same time.

[0013] Optionally, a baffle is provided on the outer side of the rotating disk. The baffle surrounds the rotating disk and is fixed relative to the rotating disk. Four inlets and outlets are provided on the baffle, and the four inlets and outlets correspond to the four mounting seats one by one.

[0014] A plurality of guiding tracks are provided on the end surface of the baffle close to the rotating disk. After the rotor is fixed on the positioning seat, the two protruding portions on the cover body are located between the positioning seat and the baffle. During the rotation of the rotating disk, the protruding portions abut against the plurality of guiding tracks, and the cover body rotates relative to the housing.

[0015] By adopting the above technical solution, under the action of the guiding tracks, when the rotating disk drives the rotor to rotate as a whole, the cover body drives the core body to rotate relative to the housing, so that the damping oil inside the rotor can be more uniform before the damping force detection, thereby improving the accuracy of the damping force detection of the rotor.

[0016] Optionally, the detection mechanism includes a detection body for detecting the rotor, a second driving member for driving the detection body to move, a third driving member for driving the detection body to rotate, and a control member for collecting detection data. Two grooves for cooperating with the protruding portions are provided at one end of the detection body close to the rotating disk.

[0017] By adopting the above technical solution, after the second driving member drives the detection body to move, the third driving member drives the detection body to rotate. During the rotation of the detection body, the two protruding portions can enter the corresponding grooves. The continuous rotation of the detection body drives the cover body and the core body to rotate relative to the housing, reducing the extrusion wear of the detection body on the rotor during the detection process and also improving the accuracy of the detection data.

[0018] Optionally, after each rotation of the detection body by the third driving member, the position of the groove on the detection body after rotation is the same as that before rotation, and the two grooves on the detection body are located in the same horizontal plane.

[0019] The guiding track is of an arc structure. After the rotor moves through a plurality of guiding tracks, the two protruding portions on the cover body are located in the same horizontal plane.

[0020] By adopting the above technical solution, when the rotating disk rotates the rotor to a position close to the detection mechanism, the two grooves on the detection body correspond to the two protruding portions on the rotor cover body one by one. After the second driving member drives the detection body to move, the two protruding portions can enter the corresponding grooves, eliminating the step of rotating the detection body to align the grooves with the protruding portions, making the process of the detection mechanism detecting the damping force of the rotor more convenient and further reducing the wear of the rotor during the damping force detection process.

[0021] Optionally, the elimination component includes a first moving member for contacting the rotor, a fourth driving member for driving the first moving member to move, and a first collection box for collecting the eliminated rotors. During the movement of the first moving member, the end portion of the first moving member slides through the relief groove on the positioning seat, and the first collection box is located on one side of the rotating disc.

[0022] By adopting the above technical solution, according to the detection result of the detection mechanism, the sorting mechanism can conveniently collect the rotors that fail the detection uniformly.

[0023] Optionally, the retention component is similar in structure to the elimination component, including a second moving member, a fifth driving member, and a second collection box. It further includes a sorting member for sorting the qualified rotors detected and a sixth driving member for driving the sorting member to move. A plurality of sorting channels are formed on the sorting member. After the sorting member moves, there is always a sorting channel aligned and communicated with the adjacent inlet and outlet. The second collection box has a plurality of mutually independent collection slots, and the ends of the plurality of sorting channels away from the rotating disc respectively correspond to the plurality of collection slots one by one.

[0024] By adopting the above technical solution, according to the detection result of the detection mechanism, the sorting mechanism can conveniently collect the qualified rotors detected, and can collect the qualified rotors according to the magnitude of the damping force.

[0025] Optionally, the plurality of sorting channels are all inclined, and the inclination degree of the sorting channels decreases in the direction away from the rotating disc.

[0026] By adopting the above technical solution, the speed of the qualified rotors moving along the sorting channels can be gradually reduced, thereby reducing the adverse impact on the quality of the rotors when the rotors fall into the second collection box during the collection process.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. High degree of automation, capable of automatically feeding and detecting the rotors, and capable of automatically eliminating and collecting the unqualified rotors and sorting and collecting the qualified rotors according to the detection results, making the damping force detection process of the rotors more convenient and efficient;

[0029] 2. During the process of transporting the rotors to the detection position, the core of the rotor can be rotated relative to the housing before detection, so that the damping oil inside the rotor is more uniform, reducing the influence of the uneven distribution of the damping oil inside the rotor on the detection result and improving the detection accuracy;

[0030] When the rotor is transported to the detection position, the two protruding parts of the upper cover of the rotor can correspond to the two grooves on the detection body one by one, making the detection process more convenient and reducing the wear on the rotor during the detection process.

[0041] The following further describes the present application in detail with reference to Figures 1-9 the accompanying drawings.

[0042] An embodiment of the present application discloses a detection and classification device for an automotive handle rotor.

[0043] Referring to Figure 1 and Figure 2 , the detection and classification device is used to detect the damping force existing during the relative rotation of the core 12 and the housing 11 in the rotor 1, and classify the rotor 1 according to the detection result. The rotor 1 includes a housing 11, a core 12, and a cover 13, and the rotor 1 is a cylindrical structure as a whole.

[0044] Referring to Figure 3 and Figure 4 , the detection and classification device includes a machine body 2, a loading mechanism 3, a transport mechanism 4, a detection mechanism 5, and a classification mechanism 6. The loading mechanism 3, the transport mechanism 4, the detection mechanism 5, and the classification mechanism 6 are all installed on the machine body 2, and the bottom of the machine body 2 is fixedly connected to the ground. A plurality of rotors 1 are successively moved onto the transport mechanism 4 through the loading mechanism 3. The transport mechanism 4 moves the rotor 1 to the position of the detection mechanism 5 to detect its own damping force. After the detection is completed, the transport mechanism 4 moves the rotor 1 to the position of the classification mechanism 6 again, and the classification mechanism 6 collects the rotor 1 at different positions for blanking according to the detection result.

[0045] Referring to Figure 5 and Figure 6, the feeding mechanism 3 includes a vibrating bowl 31 and a feeding track 32. The vibrating bowl 31 contains a number of rotors 1. The vibrating bowl 31 can transport the rotors 1 one by one and transport the rotors 1 in a predetermined position state during the transportation process. When the rotor 1 is about to be transported away from the vibrating bowl 31, at this time, the axis of the rotor 1 is horizontal, and the rib 113 of the housing 11 is located at the top position of the housing 11 at this time. In this embodiment, since the vibrating bowl 31 is a common existing technology, it will not be elaborated here.

[0046] Referring to Figure 3 and Figure 6 , one end of the feeding track 32 in the length direction is fixedly connected to the outlet position of the vibrating bowl 31. After the rotor 1 is transported away from the vibrating bowl 31, it can continue to move along the feeding track 32 while maintaining its position state. The moving direction of the rotor 1 on the feeding track 32 is the same as the direction of its own axis.

[0047] Referring to Figure 6 and Figure 7 , guiding members 321 for further adjusting the position state of the rotor 1 are installed on both sides of the feeding track 32. The two guiding members 321 and the feeding track 32 together enclose a space for the rotor 1 to move through. One ends of the two guiding members 321 are respectively fixedly connected to both sides of the feeding track 32. There is a clearance space 322 between the other ends of the two guiding members 321 for the rib 113 on the housing 11 of the rotor 1 to move through. The guiding member 321 is provided with a chamfer 3211 at a position near the vibrating bowl 31 of the clearance space 322. After the rotor 1 is transported away from the vibrating bowl 31, the rib 113 on the housing 11 of the rotor 1 contacts the chamfer 3211 position of the guiding member 321. With the assistance of the chamfer 3211, the position of the rib 113 on the housing 11 of the rotor 1 gradually becomes centered relative to the housing 11, and finally the rotor 1 continues to move on the feeding track 32 while maintaining the position state where the rib 113 on the housing 11 is located directly above the housing 11 vertically.

[0048] Referring to Figure 3 and Figure 7 , one end of the feeding track 32 away from the vibrating bowl 31 leads to the transporting mechanism 4. The transporting mechanism 4 includes a rotating disk 41 for carrying the rotor 1 to move and a first driving member 42 for driving the rotating disk 41 to rotate. The bottom of the first driving member 42 is fixedly connected to the machine body 2, the rotating disk 41 is fixedly connected to the top of the first driving member 42. The rotating disk 41 is a disk-shaped structure. The rotation axis of the rotating disk 41 is vertical, and the rotation axis of the rotating disk 41 coincides with its own axis.

[0049] Referring to Figure 7 and Figure 8, the transport mechanism 4 further includes a baffle 43 for reducing the probability of the rotor 1 being thrown out from the rotating disk 41. The baffle 43 is fixed relative to the rotating disk 41. In this embodiment, preferably, the bottom of the baffle 43 is fixedly connected to the machine body 2. The baffle 43 is arranged along the circumference of the rotating disk 41, and the baffle 43 surrounds the rotating disk 41. There is a very small distance between the rotating disk 41 and the baffle 43 to facilitate the rotation of the rotating disk 41. Four inlets and outlets 431 for the rotor 1 to enter and exit are provided on the baffle 43, and the four inlets and outlets 431 are circumferentially arranged on the baffle 43 with the axis of the rotating disk 41 as the center line. The end of the feeding track 32 away from the vibrating disk 31 is fixedly connected to the baffle 43, and the end of the feeding track 32 away from the vibrating disk 31 communicates with one of the inlets and outlets 431.

[0050] Four positioning seats 411 for fixing the rotor 1 are installed on the rotating disk 41. The four positioning seats 411 are all located at the position of the rotating disk 41 close to the baffle 43, and the four positioning seats 411 are also circumferentially arranged on the rotating disk 41 with the axis of the rotating disk 41 as the center line. Each time the first driving member 42 drives the rotating disk 41 to rotate by 1 / 4 of a turn, and the opening and closing of the first driving member 42 is periodic. After each rotation of the rotating disk 41 ends, there is always a positioning seat 411 aligned with the inlet and outlet 431 along the moving direction of the rotor 1 on the feeding track 32. In this embodiment, preferably, the first driving member 42 is a motor.

[0051] Refer to Figure 2 and Figure 8 , a positioning groove 4111 and a relief groove 4112 for the rotor 1 to enter and be fixed are provided on the positioning seat 411. The positioning groove 4111 is opened in the horizontal direction, and one end of the positioning groove 4111 penetrates through the side of the positioning seat 411 close to the baffle 43. The relief groove 4112 is located above the positioning groove 4111, and the relief groove 4112 communicates with the positioning groove 4111 and penetrates through the side of the positioning seat 411 close to the baffle 43, the side of the positioning seat 411 away from the baffle 43, and the top of the positioning seat 411. After the rotor 1 leaves the feeding track 32 and passes through the inlet and outlet 431, it can enter the positioning groove 4111 and the relief groove 4112 along the original moving direction. After the rotor 1 enters the positioning groove 4111 and the relief groove 4112, the rotation of the rotor 1 along its axis direction is restricted by the positioning seat 411. At this time, the convex portion 132 on the cover body 13 of the rotor 1 is located outside the positioning groove 4111 and there is a distance between the convex portion 132 and the baffle 43.

[0052] Refer to Figure 3 and Figure 4 , the detection mechanism 5 is located at a position on one side of the rotating disk 41 close to another inlet and outlet 431. The inlet and outlet 431 corresponding to the detection mechanism 5 is adjacent to the inlet and outlet 431 corresponding to the feeding mechanism 3. After the rotor 1 is fed onto the positioning seat 411 and fixed, the rotating disk 41 rotates to drive the rotor 1 to move closer to the detection mechanism 5.

[0053] Reference Figure 3 and Figure 5 As shown in FIGS. 4 and 5, the detecting mechanism 5 includes a detecting body 51 for detecting the damping force of the rotor 1, a control member 52 for collecting detection data, a second driving member 53 for driving the detecting body 51 to move, a third driving member 54 for driving the detecting body 51 to rotate, and a base 55 for supporting the above structure. The detecting body 51 is integrally a cylindrical structure, the axis of the detecting body 51 is horizontal and aligned with the other inlet / outlet 431, the third driving member 54 is fixedly connected to the end of the detecting body 51 away from the rotating disk 41, the second driving member 53 is fixedly connected to the third driving member 54, and the second driving member 53 is located on the side of the third driving member 54 away from the detecting body 51. The bottom of the base 55 is fixedly connected to the machine body 2, and the second driving member 53 is fixedly installed on the base 55. The third driving member 54 and the detecting body 51 are both slidably connected to the base 55. The second driving member 53 drives the third driving member 54 and the detecting body 51 to slide horizontally. During the sliding process of the detecting body 51, it can enter and exit from the inlet / outlet 431. The second driving member 53 drives the detecting body 51 to rotate about its own axis. The bottom of the control member 52 is also fixedly connected to the machine body 2, and the control member 52 is located on one side of the base 55.

[0054] Reference Figure 2 and Figure 5 As shown in FIGS. 5 and 6, two grooves 511 for adapting to the convex portions 132 on the cover body 13 are provided at the end of the detecting body 51 away from the second driving member 53. After the second driving member 53 drives the detecting body 51 to penetrate into the inlet / outlet 431 and abut against the rotor 1 on the positioning seat 411, the third driving member 54 drives the detecting body 51 to rotate. The detecting body 51 drives the cover body 13 to rotate through the plug-in fit between the grooves 511 and the convex portions 132. The rotation of the cover body 13 drives the core body 12 to rotate relative to the housing 11. The detecting body 51 transmits the data of the force required to rotate the cover body 13 to the control member 52, and the control member 52 displays the damping force of the rotor 1 through calculation. In this embodiment, the second driving member 53 is preferably a cylinder, and the third driving member 54 is preferably a motor.

[0055] Reference Figure 3 and Figure 9 As shown in FIGS. 6 and 7, a plurality of guiding tracks 432 are further installed on the side of the baffle 43 close to the rotating disk 41. The plurality of guiding tracks 432 are all located at the position between the inlet / outlet 431 corresponding to the feeding mechanism 3 and the inlet / outlet 431 corresponding to the detecting mechanism 5 on the baffle 43. In this embodiment, preferably, four guiding tracks 432 are installed. At this time, during the process of the rotor 1 moving from the feeding mechanism 3 to the detecting mechanism 5, a relative rotation of 270°-360° will occur between the core body 12 and the housing 11. According to different rotation requirements, more guiding tracks 432 can also be installed in other embodiments.

[0056] Reference Figure 2, Figure 8 and Figure 9 , the four guiding rails 432 are all arc plate structures. The inclination degree of the guiding rail 432 gradually decreases along the moving direction of the rotor 1. The guiding rail 432 inclines upward along the moving direction of the rotor 1. The normal direction at one end of the guiding rail 432 is vertical, and the normal direction at the other end of the guiding rail 432 is horizontal. During the rotation of the rotating disk 41, there is a spacing between the positioning seat 411 and the guiding rail 432, and the convex part 132 on the cover body 13 of the rotor 1 will contact the guiding rail 432.

[0057] The first guiding rail 432 is used to drive the cover body 13 to rotate relative to the housing 11 until the two convex parts 132 on the cover body 13 are located on the same vertical line. The part of the guiding rail 432 close to the end with a vertical normal direction is the rotating part 4321, and the other part is the fixed part 4322. The fixed part 4322 is fixedly connected to the baffle 43. The rotating part 4321 can rotate relative to the fixed part 4322. At the rotational connection position of the guiding rail 432 and the rotating part 4321, a structure for driving the rotating part 4321 to remain integral with the fixed part 4322 is installed. In this embodiment, preferably, this structure is a torsion spring. Since the torsion spring is a common prior art, it will not be elaborated here. The rotating part 4321 can rotate towards the direction close to the rotating disk 41, and after the rotating part 4321 rotates, it will automatically reset under the action of the torsion spring.

[0058] Refer to Figure 2 and Figure 9, when the rotor 1 moves with the two convex portions 132 on the cover body 13 located on the same vertical line, the rotor 1 can smoothly pass through the first guiding track 432 while maintaining its original state; when the rotor 1 moves with the two convex portions 132 on the cover body 13 located on the same horizontal line, one convex portion 132 on the cover body 13 will first contact the fixing portion 4322. During the movement of the rotor 1, this convex portion 132 rotates away from the fixing portion 4322 under the guidance of the fixing portion 4322, and the straight line where the two convex portions 132 are located starts to incline and the inclination gradually increases until the convex portion 132 at the lower end of the inclination contacts the rotating portion 4321. At this time, if the rotor 1 continues to move, the convex portion 132 at the upper end of the inclination is subjected to the reaction force from its contact with the fixing portion 4322. The reaction force drives the convex portion 132 at the upper end of the inclination to rotate away from the fixing portion 4322 and at the same time drives the convex portion 132 at the lower end of the inclination to rotate towards the rotating portion 4321. At this time, the convex portion 132 at the lower end of the inclination has two acting forces on the rotating portion 4321, and the sum of the two acting forces is greater than the acting force of the torsion spring on the rotating portion 4321. The convex portion 132 at the lower end of the inclination will drive the rotating portion 4321 to rotate. At the same time, the inclination of the straight line where the two convex portions 132 on the cover body 13 are located gradually increases until the convex portion 132 at the lower end of the inclination separates from the rotating portion 4321, and then the inclination of the straight line where the two convex portions 132 on the cover body 13 are located will continue to increase until the two convex portions 132 on the cover body 13 are located on the same vertical line. At this time, the rotor 1 can pass through the first guiding track 432 with the two convex portions 132 on the cover body 13 located on the same vertical line;

[0059] When the rotor 1 moves with the straight line where the two convex portions 132 on the cover body 13 are located inclined and the inclination direction is opposite to that of the first guiding track 432, during the movement of the rotor 1, the convex portion 132 at the lower end of the inclination will first contact the rotating portion 4321. At this time, the acting force of the convex portion 132 at the lower end of the inclination on the rotating portion 4321 caused by the movement of the rotor 1 is less than the acting force of the torsion spring on the rotating portion 4321. The continuous movement of the rotor 1 will drive the cover body 13 to rotate relative to the housing 11 until the two convex portions 132 on the cover body 13 are located on the same vertical line. At this time, the rotor 1 can pass through the first guiding track 432 with the two convex portions 132 on the cover body 13 located on the same vertical line;

[0060] When the rotor 1 is inclined with respect to the straight line where the two protruding parts 132 on the cover body 13 are located, and the inclination direction is the same as that of the first guiding track 432, during the movement of the rotor 1, both of the two protruding parts 132 may come into contact with the guiding track 432 first. When the protruding part 132 at the upper end of the inclination first contacts the fixing part 4322, the continuous movement of the rotor 1 will drive the cover body 13 to rotate relative to the housing 11 in the direction of the tendency that the two protruding parts 132 are on the same vertical line. During this period, the changes of the two protruding parts 132 on the cover body 13 are the same as those in the above situation, so they will not be elaborated here; when the protruding part 132 at the lower end of the inclination first contacts the rotating part 4321, the continuous movement of the rotor 1 will drive the protruding part 132 at the upper end of the inclination to rotate towards the direction close to the fixing part 4322 until the two protruding parts 132 respectively contact the fixing part 4322 and the rotating part 4321. After that, the continuous movement of the rotor 1 will drive the cover body 13 to rotate relative to the housing 11 in the direction of the tendency that the two protruding parts 132 are on the same vertical line. During this period, the changes of the two protruding parts 132 on the cover body 13 are the same as those in the above situation, so they will not be elaborated here either.

[0061] Regardless of the relative position relationship of the two protruding parts 132 on the cover body 13 of the rotor 1, after the rotor 1 moves through the guidance of the first guiding track 432, the two protruding parts 132 of the cover body 13 on the rotor 1 will be on the same vertical line.

[0062] Refer to Figure 2 and Figure 9 As shown in and, the second guiding track 432 is used to drive the cover body 13 to rotate relative to the housing 11 until the two protruding parts 132 on the cover body 13 are on the same horizontal line. The inclination direction of the second guiding track 432 is the same as that of the first guiding track 432. After the rotor 1 moves through the first guiding track 432, the protruding part 132 located below on the cover body 13 will first contact the second guiding track 432. At this time, when the rotor 1 continues to move, the protruding part 132 located below on the cover body 13 will rotate away from the guiding track 432 and the protruding part 132 above will rotate towards the guiding track 432 until the two protruding parts 132 on the cover body 13 are on the same horizontal line. Only then can the rotor 1 smoothly pass through the second guiding track 432 while maintaining its current position state.

[0063] The structure of the third guiding track 432 is the same as that of the first guiding track 432, and the structure of the fourth guiding track 432 is the same as that of the second guiding track 432. The position changes of the two protruding parts 132 on the cover body 13 when the rotor 1 moves through the third guiding track 432 and the fourth guiding track 432 are the same as the above by the same token. Therefore, this embodiment will not be elaborated here.

[0064] Refer to Figure 1 and Figure 5, the rotating disk 41 rotates and drives the loaded rotor 1 to move 1 / 4 of a circle, at which time the axis of the rotor 1 coincides with the axis of the detection body 51, and the two protrusions 132 on the cover 13 of the rotor 1 are aligned one by one with the two grooves 511 on the detection body 51. In order to make the grooves 511 on the detection body 51 be aligned with the protrusions 132 on the cover 13 of the rotor 1 every time the rotor 1 is detected, the third driving member 54 drives the detection body 51 to rotate before and after, and the relative positions of the two grooves 511 on the detection body 51 remain unchanged, and the two grooves 511 on the detection body 51 are located on the same horizontal line.

[0065] Reference Figure 3 and Figure 4 The classification mechanism 6 includes an elimination component 61 for eliminating unqualified rotors 1, and the elimination component 61 is located on the side of the rotating disk 41 away from the feeding mechanism 3. The elimination component 61 includes a first moving member 611 for driving the rotor 1 to separate from the positioning seat 411, a fourth driving member 612 for driving the first moving member 611 to move, and a first collection box 613 for collecting unqualified rotors 1. The first collection box 613 is fixedly mounted on the body 2, and the first collection box 613 is located on one side of the rotating disk 41. The first collection box 613 has a separate collection slot, and the collection slot opens vertically upward. After the unqualified rotor 1 is separated from the positioning seat 411, it can pass through the inlet and outlet 431 and fall into the collection slot of the first collection box 613.

[0066] The first moving member 611 and the fourth driving member 612 are fixed relative to the rotating disk 41. In this embodiment, the fourth driving member 612 is preferably fixedly connected to the body 2, the first moving member 611 is fixedly connected to the fourth driving member 612, and the first moving member 611 is located on the side of the fourth driving member 612 close to the rotating disk 41. The fourth driving member 612 drives the first moving member 611 to move in a direction parallel to the moving direction of the rotor 1 on the loading track 32, and the end of the first moving member 611 away from the fourth driving member 612 can pass through the yielding groove 4112 of the adjacent positioning seat 411 during the movement of the first moving member 611. The baffle 43 is installed with a lower hopper 433 at one end close to the elimination component 61 to facilitate it to fall into the first collection box 613 for collection. The lower hopper 433 is located on the side of the baffle 43 away from the rotating disk 41 and tilted downward, and the lower hopper 433 is communicated with the adjacent inlet and outlet 431. In this embodiment, the fourth driving member 612 is preferably a cylinder.

[0067] Reference Figure 3 and Figure 4, the sorting mechanism 6 further includes a retaining component 62 for classifying and collecting the qualified rotors 1 according to the detection values. The retaining component 62 is located on the side of the rotating disk 41 away from the detection mechanism 5. The retaining component 62 includes a second moving member 621 for driving the rotor 1 to separate from the positioning seat 411, a fifth driving member 622 for driving the second moving member 621 to move, and a second collection box 623 for collecting the qualified rotors 1 classified. In this embodiment, the second moving member 621, the fifth driving member 622, and the second collection box 623 are correspondingly similar in structure to the first moving member 611, the fourth driving member 612, and the first collection box 613, and the relative positional relationship with the corresponding positioning seat 411 is the same. The fifth driving member 622 is also preferably a cylinder, so it will not be introduced separately here.

[0068] The difference between the second collection box 623 and the first collection box 613 is that the second collection box 623 has several independent collection slots for different rotors 1 to fall into after classification. In this embodiment, it is preferably to classify the qualified rotors 1 into three categories: low, medium, and high according to the detection value of their damping force. The specific classification criteria are set by the operator on the control member 52. After collecting the detection data, the control member 52 can control the elimination component 61 and the retaining component 62 respectively, so that the rotor 1 separates from the positioning seat 411 at a suitable place according to its own detection data and enters the corresponding collection slot.

[0069] Refer to Figure 3 and Figure 4 , for the convenience of the rotor 1 falling into the corresponding collection slot on the second collection box 623 after separating from the positioning seat 411, the retaining component 62 further includes a classification member 624 and a sixth driving member 625 for driving the classification member 624 to move. The sixth driving member 625 is fixed relative to the rotating disk 41. In this embodiment, it is preferably that the sixth driving member 625 is fixedly connected to the body 2, the classification member 624 is fixedly connected to the sixth driving member 625, and the classification member 624 is located on the side of the baffle 43 away from the rotating disk 41. The direction in which the sixth driving member 625 drives the classification member 624 to move is parallel to the moving direction of the first moving member 611. In this embodiment, the sixth driving member 625 is preferably a cylinder.

[0070] Three classification channels 6241 are correspondingly formed on the classification member 624. One ends of the three classification channels 6241 close to the baffle 43 are adjacent, and spaces are left between the other ends of the three classification channels 6241 away from the baffle 43. One end of the classification channel 6241 close to the baffle 43 communicates with the adjacent inlet / outlet 431, and the other end of the classification channel 6241 away from the baffle 43 is located above the second collection box 623. The classification channels 6241 are all inclined downward, and the inclination degree of each part of the classification channel 6241 is inversely proportional to the distance between it and the baffle 43.

[0071] The control member 52 compares the detected damping force value of the rotor 1 with a preset value to determine the classification type of the rotor 1, and controls the sixth driving member 625 to drive the classification member 624 to move to the classification channel 6241 corresponding to the type and communicate with the adjacent inlet and outlet 431. When the rotating disk 41 rotates to drive the rotor 1 to move to a position close to the inlet and outlet 431, the control member 52 then controls the fifth driving member 622 to drive the second moving member 621 to push the rotor 1, so that the rotor 1 is separated from the positioning seat 411 and falls into the corresponding collection groove on the second collection box 623 through the corresponding classification channel 6241 for collection.

[0072] The implementation principle of the detection and classification device for the automotive handle rotor in the embodiment of the present application is as follows:

[0073] A number of rotors 1 to be detected for damping force are fed through the vibrating disk 31 while the preliminary position state of the rotors 1 during feeding is adjusted. Then the rotor 1 enters the feeding track 32, and the feeding track 32 adjusts the secondary position state of the rotor 1. After the rotor 1 leaves the feeding track 32, it passes through the inlet and outlet 431 and is fixed on the positioning seat 411. Then the first driving member 42 drives the rotating disk 41 to rotate by 1 / 4 turn, moving the rotor 1 in the direction close to the detection mechanism 5. During the movement of the rotor 1, a number of guiding tracks 432 drive the cover body 13 to drive the core body 12 to rotate relative to the housing 11, making the distribution of the damping oil inside the rotor 1 more uniform and improving the accuracy of the detected damping force value. At the same time, a number of guiding tracks 432 will drive the moved rotor 1 to keep the two protruding portions 132 on its cover body 13 on the same horizontal line;

[0074] Then the second driving member 53 drives the detection body 51 to move so that the two protruding portions 132 are respectively inserted into the two grooves 511. Then the third driving member 54 drives the detection body 51 to rotate to drive the cover body 13 and the core body 12 to rotate. At the same time, the control member 52 collects the detection values during the rotation process and controls the classification mechanism 6 through the detection values;

[0075] When the detected damping force result of the rotor 1 is unqualified, the first driving member 42 drives the rotating disk 41 to rotate again. After the rotor 1 moves to a position close to the elimination assembly 61, the control member 52 will control the fourth driving member 612 to drive the first moving member 611 to separate the rotor 1 from the positioning seat 411 and fall into the collection groove of the first collection box 613 through the inlet and outlet 431 and the discharge hopper 433 for collection;

[0076] When the damping force detection result of the rotor 1 is qualified, the control member 52 will classify the rotor 1 according to the detection data, and control the sixth driving member 625 to drive the classification member 624 to move to the corresponding classification channel 6241 to communicate with the inlet and outlet 431 and the corresponding collection groove on the second collection box 623. Then, the first driving member 42 drives the rotating disk 41 to rotate again. After the rotor 1 moves to a position close to the retention assembly 62, the control member 52 will control the fifth driving member 622 to drive the second moving member 621 to separate the rotor 1 from the positioning seat 411 and drop it into the corresponding collection groove of the second collection box 623 through the corresponding classification channel 6241 for collection.

[0077] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
