Description

Technical Field

[0001] This utility model specifically relates to a rotor directional feeding device. Background Technology

[0002] The ignition switch of existing motorcycles or electric vehicles connects and disconnects the circuit through a rotor. The rotor drives the moving contact to make contact with the external stationary contact. When the rotation causes the moving contact to make contact with the external stationary contact, it can activate the corresponding circuit system, so that the circuit system outputs power to connect with the vehicle and allows the vehicle to use electricity.

[0003] To meet the requirements of large-volume and efficient rotor assembly, a corresponding rotor assembly machine needs to be designed, which inevitably involves a feeding device for the orderly transport of rotors. (See attached document). Figure 1 , 2 The rotor structure shown has irregularly shaped and positioned holes at its upper end. In subsequent assembly processes, springs need to be precisely assembled within specific holes at the upper end of the rotor, and these springs are used to connect conductive contacts. The structure of the holes on the upper part of the rotor and their relative positions clearly demonstrate that the rotor must be positioned in a specific direction during loading to ensure efficient and accurate assembly during subsequent operations in the rotor assembly machine.

[0004] Therefore, when designing a feeding device, it is essential to consider how to ensure that "all rotors maintain the same orientation". Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a rotor orientation feeding device to address the shortcomings of the prior art, so as to ensure that all rotors meet the orientation consistency requirements before entering the subsequent assembly process, and avoid problems such as spring misalignment and contact failure caused by incorrect orientation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotor orientation feeding device, comprising a frame, characterized in that: the frame is provided with a rotor sorting feeding component for orderly transporting several sets of rotors, a clamping feeding component for orderly transporting several sets of rotor clamps, and a pre-rotating component distributed between the rotor sorting feeding component and the clamping feeding component; the frame is also provided with a first transfer mechanism for transferring the rotor from the rotor sorting feeding component to the pre-rotating component and / or for transferring the rotor from the pre-rotating component to the rotor clamp within the clamping feeding component; the pre-rotating component is used to rotate the rotor; the frame is also provided with a detection component and a correction rotating component distributed above the clamping feeding component; the detection component is used to detect the direction of the rotor within the rotor clamp; when the detection component detects that the rotor needs to be adjusted in direction, the correction rotating component rotates the rotor whose direction needs to be adjusted.

[0007] Using the above technical solution, during the operation of this device, the rotor is first transported by the rotor sorting and loading component, entering the loading process in a preliminary orderly state. The first transfer mechanism transfers the rotor from the rotor sorting and loading component to the pre-rotating component, which performs preliminary rotational adjustment on the rotor, ensuring that its direction is close to the target state or that the rotated direction already maintains the target state. Both directions ensure that the rotor can be smoothly clamped into the rotor fixture. The adjusted rotor is placed in the rotor fixture of the fixture sorting and loading component via the first transfer mechanism, and the rotor fixture moves orderly with the fixture sorting and loading component. When the rotor fixture moves to below the detection component, the detection component detects the direction of the rotor in the fixture in real time. If the rotor direction is still detected to deviate from the set direction, the correction rotating component operates, and the correction rotating component rotates and adjusts the rotor again until its direction meets the requirements. Finally, all the corrected rotors enter the subsequent assembly process with the rotor fixture, ensuring that operations such as spring installation and contact plate connection can be completed efficiently and accurately. The rotor sorting and feeding unit uses an orderly transport function to initially arrange several groups of rotors into a set order, avoiding feeding blockages caused by rotor stacking or directional confusion. A pre-rotating component performs preliminary directional adjustment before the rotors enter the rotor fixture, ensuring smooth clamping. The first transfer mechanism ensures continuous rotor flow between the sorting and feeding unit, the pre-rotating component, and the rotor fixture, preventing delays or misalignments from affecting overall efficiency. The detection component detects rotors that have not been successfully oriented, and the correction rotating component performs final correction for detected directional deviations. Through rotation, it ensures that all rotors meet strict directional consistency requirements before entering subsequent assembly processes, avoiding problems such as spring misalignment and contact failure caused by incorrect orientation.

[0008] The aforementioned rotor orientation feeding device can be further configured as follows: the rotor sorting feeding component includes a first vibrating feeder and a rotor sorting guide rail installed above the first vibrating feeder. The rotor sorting guide rail is provided with rotor conveying grooves arranged along the axial direction of the rotor sorting guide rail. A positioning block is connected to the end of the rotor sorting guide rail facing the pre-rotating component. The positioning block is provided with a rotor positioning groove. The side of the rotor positioning groove facing the rotor sorting guide rail is provided with an opening, and the rotor positioning groove communicates with the rotor conveying groove through the opening.

[0009] Using the above technical solution, during device operation, the first vibrating feeder achieves continuous and stable conveying of the rotor on the rotor sorting guide rail through regular vibration. Through the rotor conveying trough, the rotor maintains a specific posture during movement, initially screening and arranging rotors with relatively consistent orientations, reducing the complexity of subsequent orientation adjustments. During movement, the rotor conveying trough and the rotor shape form a guide, and several groups of rotors initially form a relatively consistent orientation arrangement. When the rotor is conveyed by vibration to the end of the rotor sorting guide rail facing the pre-rotating component, it enters the rotor positioning slot of the positioning block through the opening. At this point, the first transfer mechanism can accurately grab the rotor that has completed the initial sorting from the rotor positioning slot and transfer it to the pre-rotating component for subsequent adjustments.

[0010] The aforementioned rotor orientation feeding device can be further configured as follows: the pre-rotating component includes a first rotary cylinder and a positioning seat linked to the output end of the first rotary cylinder. The positioning seat is provided with a positioning structure. When the first transfer mechanism transfers the rotor from the rotor conveying trough to the positioning structure on the positioning seat, the first rotary cylinder drives the positioning seat to rotate, and then the positioning structure synchronously drives the rotor to rotate.

[0011] Using the above technical solution, when the first transfer mechanism transfers the rotor, which has been initially sorted by the rotor sorting guide rail, to the positioning structure of the positioning seat, the positioning structure can be configured as a positioning hole adapted to the bottom of the rotor or a protrusion inserted into the bottom of the rotor, so that the positioning structure and the rotor engage, fixing the rotor to the positioning seat. At this time, the output end of the first rotary cylinder drives the positioning seat to rotate synchronously (the rotation angle is determined by the deviation between the rotor's target direction and the current detection direction, usually 90 degrees). Due to the effect of the positioning structure, the rotor rotates synchronously with the positioning seat until it reaches the initially set direction requirement or directly reaches the required direction. After the initial rotation is completed, the first rotary cylinder stops operating, and the first transfer mechanism transfers the rotor from the positioning seat to the rotor fixture for sorting and loading parts in the fixture, entering the subsequent detection and final calibration process.

[0012] The aforementioned rotor orientation feeding device can be further configured as follows: the first transfer mechanism includes a first main transfer plate and a first auxiliary transfer plate. One end of the first main transfer plate is linked to a first gripper cylinder for transferring the rotor from the rotor positioning slot to the positioning structure, and the other end of the first main transfer plate is linked to a second gripper cylinder for transferring the rotor from the positioning structure to the rotor fixture. The first main transfer plate is linked to a first cylinder for driving the first main transfer plate to reciprocate vertically. The body of the first cylinder is mounted on the first auxiliary transfer plate. The first main transfer plate is linked to a first slider, which is slidably engaged with a first slide rail mounted on the first auxiliary transfer plate. The first auxiliary transfer plate is linked to a second cylinder for driving the first auxiliary transfer plate to reciprocate horizontally. The body of the second cylinder is fixed to the frame. The first auxiliary transfer plate is linked to a second slider, which is slidably engaged with a second slide rail mounted on the frame.

[0013] Using the above technical solution, the second cylinder drives the first auxiliary transfer plate to move horizontally along the second slide rail until the first gripper cylinder on the first main transfer plate aligns with the positioning block (rotor positioning slot) at the end of the rotor sorting guide rail. Simultaneously, the second gripper cylinder on the first main transfer plate aligns with the positioning structure. Then, the first cylinder activates, pushing the first main transfer plate vertically downwards along the first slide rail. The grippers of the first gripper cylinder open and hold the rotor in the rotor positioning slot, while the grippers of the second gripper cylinder open and hold the rotor at the positioning structure. The first cylinder reverses its action, causing the first main transfer plate to rise vertically, disengaging one set of rotors from the positioning slot and the other set from the positioning structure. The second cylinder then activates again, driving the first auxiliary transfer plate to move horizontally in the opposite direction. The first cylinder descends again, and the first and second gripper cylinders release the rotors respectively. One set of rotors is placed on the positioning structure of the positioning seat, and the other set is placed on the rotor clamp. Throughout the process, the two gripper cylinders work synchronously, improving transfer efficiency.

[0014] The aforementioned rotor orientation feeding device can be further configured as follows: the detection component includes a detection support plate and a detection element installed at one end of the detection support plate; the other end of the detection support plate is linked to a third cylinder for driving the detection support plate to reciprocate vertically; the detection support plate is also linked to a third slider; the third slider is slidably fitted with a third slide rail; and the third slide rail is installed on the frame.

[0015] Using the above technical solution, the third cylinder is used to adjust the height of the detection element to adapt to rotors of different specifications and types, thereby improving detection accuracy. The detection element can preferably be a photoelectric sensor, a laser sensor, or similar device.

[0016] The aforementioned rotor orientation feeding device can be further configured as follows: the correction rotating component includes a rotary clamping finger cylinder and a correction support plate connected to the rotary clamping finger cylinder body. The rotary clamping finger cylinder is distributed on the side of the detection element away from the pre-rotating component. The correction support plate is linked to a fourth cylinder for driving the correction support plate to reciprocate vertically. The correction support plate is also linked to a fourth slider. The fourth slider is slidably fitted with a fourth slide rail, and the fourth slide rail is fixed on the frame.

[0017] Using the above technical solution, when it is detected that the rotor is not adjusted to the required direction, the fourth cylinder drives the correction support plate to move vertically downward along the fourth slide rail, the rotating clamping finger cylinder clamps the rotor, the fourth cylinder drives the rotating clamping finger cylinder to rise, the rotating clamping finger cylinder rotates the rotor until it reaches the required direction, the fourth cylinder drives the rotating clamping finger cylinder to move downward, and the rotor with the adjusted direction is placed on the rotor fixture.

[0018] The aforementioned rotor orientation feeding device can be further configured such that: the clamp sorting feeding component includes a clamp sorting guide rail, the clamp sorting guide rail is provided with clamp conveying grooves arranged along the axial direction of the clamp sorting guide rail, and several sets of rotor clamps are arranged in order in the clamp conveying grooves; the clamp sorting feeding component also includes a moving source for driving several sets of rotor clamps to move along the clamp conveying grooves.

[0019] Using the above technical solution, the clamp conveying trough guides the movement of several sets of rotor clamps, facilitating the placement of the rotors on the rotor clamps. The moving source can be of various types, such as a drive belt or a cylinder, as long as it enables the rotor clamps to move within the clamp conveying trough.

[0020] The aforementioned rotor orientation feeding device can be further configured as follows: the rotor clamp includes a clamping seat, and two sets of symmetrically arranged arc-shaped limiting blocks are provided above the clamping seat. There is a clamping gap between the two sets of arc-shaped limiting blocks that can accommodate the rotor. Inserts distributed between the two sets of arc-shaped limiting blocks are also provided above the clamping seat. An infeed inclined surface is provided above the arc-shaped limiting blocks. When the rotor is placed in the clamping gap, the inserts are inserted into the rotor.

[0021] Using the above technical solution, two sets of arc-shaped limiting blocks cooperate with the plug-in to clamp the rotor, preventing the rotor from deflecting during transportation and improving assembly accuracy. The inclined feed surface makes the rotor assembly into the rotor fixture smoother and less prone to interference.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 3 to 11The rotor orientation feeding device shown includes a frame, a rotor sorting and feeding component for orderly transporting several sets of rotors, a clamping and feeding component 2 for orderly transporting several sets of rotor clamps 1, and a pre-rotating component distributed between the rotor sorting and feeding component and the clamping and feeding component 2. The frame also includes a first transfer mechanism for transferring rotors from the rotor sorting and feeding component to the pre-rotating component and / or for transferring rotors from the pre-rotating component to the rotor clamps 1 within the clamping and feeding component 2. The pre-rotating component rotates the rotors. The frame also includes a detection component and a correction rotating component distributed above the clamping and feeding component 2. The detection component detects the direction of the rotors within the rotor clamps 1. When the detection component detects that the rotor needs to be adjusted, the correction rotating component rotates the rotor whose direction needs to be adjusted. During operation, the rotors are first transported by the rotor sorting and feeding component, entering the feeding process in a preliminary orderly state. The first transfer mechanism transfers the rotor from the rotor sorting and loading unit to the pre-rotating unit. The pre-rotating unit performs preliminary rotational adjustment on the rotor, ensuring its orientation is close to the target state or that the rotated orientation already maintains the target state. Both orientations ensure the rotor can be smoothly clamped into the rotor fixture 1. The adjusted rotor is then placed into the rotor fixture 1 of the fixture sorting and loading unit 2 via the first transfer mechanism. The rotor fixture 1 moves orderly with the fixture sorting and loading unit 2. When the rotor fixture 1 moves below the detection component, the detection component performs real-time detection on the orientation of the rotor within the fixture. If a deviation is detected between the rotor orientation and the set orientation, the correction rotating unit operates, rotating and adjusting the rotor again until its orientation meets the requirements. Finally, all the corrected rotors enter the subsequent assembly process with the rotor fixture 1, ensuring that operations such as spring installation and contact plate connection are completed efficiently and accurately. The rotor sorting and loading unit, through its orderly transport function, initially arranges several groups of rotors into a state arranged in a set order, avoiding loading obstruction caused by rotor stacking or orientation confusion. The pre-rotating component performs initial orientation adjustment before the rotor enters rotor fixture 1, ensuring smooth clamping of the rotor. The first transfer mechanism ensures continuous flow of the rotor between the sorting and loading components, the pre-rotating component, and rotor fixture 1, avoiding impacts on overall efficiency due to transfer delays or misalignments. The detection component detects rotors that have not been successfully oriented, and the correction rotating component performs final correction for detected directional deviations. Through rotation, it ensures that all rotors meet strict directional consistency requirements before entering subsequent assembly processes, avoiding problems such as spring assembly misalignment and contact failure caused by incorrect orientation.

[0037] The rotor sorting and feeding system includes a first vibrating feeder 3 and a rotor sorting guide rail 4 mounted above the first vibrating feeder 3. The rotor sorting guide rail 4 has rotor conveying troughs 41 arranged axially along the guide rail 4. A positioning block 6 is connected to the end of the rotor sorting guide rail 4 facing the pre-rotating component. The positioning block 6 has a rotor positioning groove 61, which has an opening on the side facing the rotor sorting guide rail 4, and the positioning groove 61 communicates with the rotor conveying trough 41 through the opening. The first vibrating feeder 3 achieves continuous and stable conveying of the rotor on the rotor sorting guide rail 4 through regular vibration. Through the rotor conveying trough 41, the rotor maintains a specific posture during movement, initially screening and arranging rotors with relatively consistent directions, reducing the complexity of subsequent direction adjustments. During movement, the rotor conveying trough 41 and the rotor shape form a guide, and several groups of rotors initially form an arrangement with relatively consistent directions. When the rotor is conveyed to the end of the rotor sorting guide 4 facing the pre-rotating component by vibration, it enters the rotor positioning groove 61 of the positioning block 6 through the opening. At this time, the first transfer mechanism can accurately grab the rotor that has completed the initial sorting from the rotor positioning groove 61 and transfer it to the pre-rotating component for subsequent adjustment.

[0038] The pre-rotating component includes a first rotary cylinder 5 and a positioning seat 7 linked to the output end of the first rotary cylinder 5. The positioning seat 7 is equipped with a positioning structure 71. When the first transfer mechanism transfers the rotor from the rotor conveying trough 41 to the positioning structure 71 on the positioning seat 7, the first rotary cylinder 5 drives the positioning seat 7 to rotate, and then the positioning structure 71 synchronously drives the rotor to rotate. When the first transfer mechanism transfers the rotor, which has been initially sorted by the rotor sorting guide rail 4, to the positioning structure 71 on the positioning seat 7, the positioning structure 71 can be configured as a positioning hole adapted to the bottom of the rotor or as a protrusion inserted into the bottom of the rotor, thus the positioning structure 71 and the rotor engage, fixing the rotor to the positioning seat 7. At this time, the first rotary cylinder 5 starts, and its output end drives the positioning seat 7 to rotate synchronously (the rotation angle is determined by the deviation between the rotor's target direction and the current detection direction, usually 90 degrees). Due to the action of the positioning structure 71, the rotor rotates synchronously with the positioning seat 7 until it reaches the initially set direction requirement or directly reaches the desired direction. After the initial rotation is completed, the first rotary cylinder 5 stops operating, and the first transfer mechanism transfers the rotor from the positioning seat 7 to the rotor fixture 1 of the fixture sorting and loading part 2, and enters the subsequent inspection and final calibration process.

[0039] The first transfer mechanism includes a first main transfer plate 8 and a first auxiliary transfer plate 9. One end of the first main transfer plate 8 is linked to a first gripper cylinder 10 for transferring the rotor from the rotor positioning slot 61 to the positioning structure 71, and the other end of the first main transfer plate 8 is linked to a second gripper cylinder 11 for transferring the rotor from the positioning structure 71 to the rotor clamp 1. The first main transfer plate 8 is linked to a first cylinder 12 for driving the first main transfer plate 8 to reciprocate vertically. The body of the first cylinder 12 is mounted on the first auxiliary transfer plate 9. The first main transfer plate 8 is linked to a first slider 13, which is slidably engaged with a first slide rail 14 mounted on the first auxiliary transfer plate 9. The first auxiliary transfer plate 9 is linked to a second cylinder 15 for driving the first auxiliary transfer plate 9 to reciprocate horizontally. The body of the second cylinder 15 is fixed on the frame. The first auxiliary transfer plate 9 is linked to a second slider 16, which is slidably engaged with a second slide rail 17 mounted on the frame. The second cylinder 15 is activated first, driving the first auxiliary transfer plate 9 to move horizontally along the second slide rail 17 until the first gripper cylinder 10 on the first main transfer plate 8 aligns with the positioning block 6 (rotor positioning groove 61) at the end of the rotor sorting guide rail 4. At the same time, the second gripper cylinder 11 on the first main transfer plate 8 aligns with the positioning structure 71. Then, the first cylinder 12 is activated, pushing the first main transfer plate 8 vertically downward along the first slide rail 14. The grippers of the first gripper cylinder 10 open and clamp the rotor in the rotor positioning groove 61, while the grippers of the second gripper cylinder 11 open and clamp the rotor at the positioning structure 71. The first cylinder 12 reverses its action, causing the first main transfer plate 8 to rise vertically, causing one set of rotors to disengage from the positioning groove and the other set of rotors to disengage from the positioning structure 71. The second cylinder 15 actuates again, driving the first auxiliary transfer plate 9 to move horizontally in the opposite direction. The first cylinder 12 descends again, and the first gripper cylinder 10 and the second gripper cylinder 11 release the rotors respectively. One set of rotors is placed on the positioning structure 71 of the positioning seat 7, and the other set of rotors is placed on the rotor clamp 1. Throughout the process, the two gripper cylinders work synchronously, improving the transfer efficiency.

[0040] The detection assembly includes a detection support plate 18 and a detection element 19 mounted on one end of the detection support plate 18. A third cylinder 20 is linked to the other end of the detection support plate 18 to drive its vertical reciprocating motion. The detection support plate 18 is also linked to a third slider 21, which is slidably fitted with a third slide rail 22, which is mounted on a frame. The third cylinder 20 is used to adjust the height of the detection element 19 to accommodate rotors of different specifications and types, thereby improving detection accuracy. The detection element 19 can preferably be a photoelectric sensor, a laser sensor, or similar device.

[0041] The calibration rotating component includes a rotary clamping finger cylinder 23 and a calibration support plate 24 connected to the body of the rotary clamping finger cylinder 23. The rotary clamping finger cylinder 23 is located on the side of the detection element 19 away from the pre-rotating component. The calibration support plate 24 is linked to a fourth cylinder 25 for driving the calibration support plate 24 to reciprocate vertically. The calibration support plate 24 is also linked to a fourth slider 26, which is slidably fitted with a fourth slide rail 27, which is fixed to the frame. When it is detected that the rotor is not adjusted to the required direction, the fourth cylinder 25 drives the calibration support plate 24 to move vertically downward along the fourth slide rail 27. The rotary clamping finger cylinder 23 clamps the rotor, and the fourth cylinder 25 drives the rotary clamping finger cylinder 23 to rise. The rotary clamping finger cylinder 23 rotates the rotor to the required direction, and the fourth cylinder 25 drives the rotary clamping finger cylinder 23 to move downward, placing the adjusted rotor on the rotor clamp 1.

[0042] The fixture sorting and loading component 2 includes a fixture sorting guide rail, on which fixture conveying grooves 28 are arranged axially along the fixture sorting guide rail. Several sets of rotor fixtures 1 are arranged in an orderly manner within the fixture conveying grooves 28. The fixture sorting and loading component 2 also includes a moving source for driving the several sets of rotor fixtures 1 to move along the fixture conveying grooves 28. The fixture conveying grooves 28 provide moving guidance for the several sets of rotor fixtures 1, facilitating the placement of rotors on the rotor fixtures 1. The moving source can be selected in various ways, such as by a drive belt or a cylinder, as long as it enables the rotor fixtures 1 to move within the fixture conveying grooves 28.

[0043] The rotor fixture 1 includes a clamping base 1-1. Above the clamping base 1-1 are two sets of symmetrically arranged arc-shaped limiting blocks 1-2. A clamping gap exists between the two sets of arc-shaped limiting blocks 1-2 to accommodate the rotor. Above the clamping base 1-1 are also inserts 1-3 distributed between the two sets of arc-shaped limiting blocks 1-2. An infeed ramp is provided above the arc-shaped limiting blocks 1-2. When the rotor is placed within the clamping gap, the inserts 1-3 are inserted into the rotor. The two sets of arc-shaped limiting blocks 1-2 cooperate with the inserts 1-3 to clamp the rotor, preventing rotor deflection during transportation and improving assembly accuracy. The infeed ramp makes the rotor assembly process into the rotor fixture smoother and less prone to interference.

[0044] The working principle of this embodiment is as follows:

[0045] First, a preferred vibratory feeder continuously transports rotors into the first direct-vibration feeder 3. The rotors are arranged in an orderly manner on the first direct-vibration feeder 3, and the direction of the rotors will appear as shown in the attached figure. Figure 3 The two cases shown.

[0046] Secondly, the rotor is transported by the first gripper cylinder 10 to the rotor positioning groove 61 and then transferred to the positioning structure 71 on the positioning seat 7. The first rotary cylinder 5 drives the rotor to rotate 90 degrees, and the direction of the rotor will be further changed as shown in the attached figure. Figure 4 In the two cases shown (both directions can achieve rotor clamping in rotor fixture 1), one direction has been rotated to the direction required for machining, but there is still a direction that does not correspond to machining.

[0047] Furthermore, the second gripper cylinder 11 continues to transport the rotor to the rotor clamp 1. When the detection element 19 detects a rotor whose orientation is still incorrect, and the rotor moves below the rotary clamping finger cylinder 23, the rotary clamping finger cylinder 23 moves down to grip the rotor and disengages it from the rotor clamp 1. It then rotates the rotor 180 degrees until the rotor orientation is as shown in the attached diagram. Figure 5 As shown, the rotor with the adjusted orientation is placed into rotor fixture 1 and transported to the next process.

[0048] It should be noted that in this embodiment, the first gripper cylinder 10 and the second gripper cylinder 11 in the first transfer mechanism work synchronously. That is, when the first gripper cylinder 10 transfers the rotor in the rotor positioning groove 61, the second gripper cylinder 11 also synchronously transfers the rotor at the positioning seat 7, resulting in high working efficiency and no delay.
