Description

Technical Field

[0001] The present application relates to the technical field of material testing, and more specifically, to a device for detecting the quality of glue application on a motor rotor and an automated motor assembly system. Background Art

[0002] Glue application on a motor rotor is a key process in motor manufacturing. In some processes, glue is applied in the rotor slots to form a glue strip material, which is used for fixing permanent magnets, insulation protection, heat dissipation optimization, and improving the overall stability of the rotor, etc.

[0003] Currently, the quality of the glue strip material formed by glue application is usually evaluated by inspectors observing the surface of the glue strip material. This method relies on manual labor and has low detection efficiency; the detection result cannot reflect the properties of the glue strip material inside the rotor slot, which is not conducive to accurately evaluating the quality of the glue strip material formed by glue application. Summary of the Invention

Through automatic detection by the detection device, the detection efficiency is high; during detection, the distribution of the glue strip material is detected along the thickness direction of the glue strip material, and the detection result can reflect the properties of the glue strip material inside the rotor slot, which is conducive to more accurately evaluating the quality of the glue strip material formed by glue application.

[0005] The embodiments of the present application are implemented as follows: In a first aspect, an embodiment of the present application provides a device for detecting the quality of glue application on a motor rotor, including: A bracket unit, the bracket unit includes a bracket base and two support members; the two support members are spaced apart along a first direction on the top of the bracket base and are used to respectively support the two rotor shafts of the motor rotor; A detection unit, the detection unit includes a vertical slide rail, a moving seat, two detection brackets, and two groups of distance sensors. The moving seat is installed on the vertical slide rail and is slidably engaged with the vertical slide rail along the vertical direction. The two detection brackets are connected to the moving seat and are spaced apart along the first direction. The two detection brackets respectively correspond to the two ends of the glue strip material in the rotor slot of the motor rotor. The two groups of distance sensors are arranged oppositely and are respectively installed on the inner side surfaces of the bottoms of the two detection brackets; A power unit, the power unit is in transmission connection with the moving seat and is used to drive the moving seat to reciprocate between a high position and a low position; when the moving seat is at the high position, the distance sensors are located above the rotor slot; when the moving seat is at the low position, the distance sensors are located in the rotor slot.

[0006] The device for detecting the quality of glue application on a motor rotor provided by the embodiment of the present application has the following beneficial effects: Configure two detection brackets corresponding to the two ends of the rubber strip material respectively. On the inner side of the bottoms of the two detection brackets, two groups of distance sensors are arranged opposite to each other. The lifting of the moving seat drives the detection brackets and the distance sensors, so that the distance sensors can extend into the rotor slots and detect from the end faces of the two ends of the rubber strip material. Among them, during the process of the distance sensors continuously extending into the rotor slots, the distance sensors correspond to the end faces at different thicknesses of the rubber strip material. This detection method detects the distribution of the rubber strip material along the thickness direction of the rubber strip material, and the detection result can reflect the properties of the rubber strip material inside the rotor slot, which is beneficial to more accurately evaluate the quality of the rubber strip material formed by caulking.

[0026] Hereinafter, the technical solutions of the present application will be exemplarily described through some embodiments.

[0027] See Figure 1 and Figure 2 First, in a first aspect, an adhesive application quality detection device 100 for a motor rotor provided by an embodiment of the present application includes a support unit 110, a detection unit 120, and a power unit 130.

[0028] It should be noted that, in the embodiments of the present application, in addition to the above functional units, the adhesive application quality detection device 100 for a motor rotor may also be conventionally configured with a device base, and the device base may be in the form of a housing, a frame, etc. Without limiting the fixing manner of the specific functional structure, the specific functional structure is, for example, fixed to the ground, a wall, or the device base.

[0029] See Figure 3 and Figure 4 As shown in and, the support unit 110 includes a support base 111 and two support members 112. Among them, the support base 111 can be fixed to the ground or to the device base. The two support members 112 are spaced apart along a first direction on the top of the support base 111, and the first direction is consistent with the axial direction of the motor rotor 200. The bottom of the support member 112 is exemplarily fixedly connected to the support base 111. The two support members 112 are used to respectively support the two rotor shafts 210 of the motor rotor 200, that is, the distance between the two support members 112 matches the axial length of the motor rotor 200. A groove matching the rotor shaft 210 can be provided at the top of the support member 112 for accommodating and fixing the rotor shaft 210; a bushing can also be connected to the top of the support member 112 for inserting and fixing the rotor shaft 210.

[0030] See Figure 5 and Figure 6The detection unit 120 includes a vertical slide rail (not shown), a moving seat 121, two detection brackets 122 and two sets of distance sensors 123. Among them, the vertical slide rail can be fixed to the ground or to the base of the device. The moving seat 121 is installed on the vertical slide rail and slidably cooperates with the vertical slide rail along the vertical direction. The two detection brackets 122 are connected to the moving seat 121 and are spaced apart along the first direction. The detection brackets 122 are, for example but not limited to, connected to the side, bottom or inside of the moving seat 121; the two detection brackets 122 respectively correspond to the two ends of the rubber strip material 230 in the rotor slot 220 of the motor rotor 200. The detection bracket 122 is, for example, a strip bracket, a columnar bracket or a plate bracket extending in the vertical direction. Two groups of distance sensors 123 are arranged opposite to each other and are respectively installed on the inner side surfaces of the bottom of the two detection brackets 122. Each group of distance sensors 123 can be provided with one or more sensors. The distance sensor 123 is, for example, a laser ranging sensor. Exemplarily, the inner side surface of the bottom of the detection bracket 122 is provided with a mounting groove, and the distance sensor 123 is exemplarily embedded in the mounting groove.

[0031] The power unit 130 is in transmission connection with the moving seat 121, and is used to drive the moving seat 121 to reciprocate between the high position and the low position. It is understandable that the power unit 130 can directly transmit the transmission to the moving seat 121, or can also transmit the transmission to the moving seat 121 indirectly. Figure 5 When the moving seat 121 is at a high position, the distance sensor 123 is located above the rotor slot 220. It should be noted that the distance sensor 123 only needs to be higher than the rotor slot 220 in the vertical direction, and is not limited to being located directly above the rotor slot 220. The distance sensor 123 can also be located obliquely above the rotor slot 220. Figure 6 When the moving seat 121 is located at the lower position, the distance sensor 123 is located in the rotor slot 220. In this state, the two groups of distance sensors 123 are respectively facing the two end surfaces of the rubber strip material 230.

[0032] The motor rotor gluing quality detection device 100 provided in the embodiment of the present application has the following working principles: In the unchecked initial state, see Figure 1 and Figure 5 , the moving seat 121 is located at a high position, and at this time the distance sensor 123 is higher than the rotor slot 220.

[0033] During the detection, the power unit 130 drives the moving seat 121 to lower until it moves to the lower position. During the lowering process of the moving seat 121, the bottom of the detection bracket 122 drives the distance sensor 123 to gradually extend into the rotor slot 220; see Figure 2 and Figure 6When the moving seat 121 is at the lowest position, the distance sensor 123 is located in the rotor slot 220. As the distance sensor 123 continues to extend into the rotor slot 220, the distance sensor 123 corresponds to the end surfaces of the rubber strip material 230 at different thicknesses. By measuring the distance between the distance sensor 123 and the end surfaces of the rubber strip material 230 at different thicknesses at both ends, the length of the rubber strip material 230 at different thicknesses can be determined. When the distance sensor 123 descends to the point where two groups of distance sensors 123 face each other, it indicates that there is no rubber strip material 230 at this depth, and the actual thickness of the rubber strip material 230 can be determined based on this.

[0034] After the detection is completed, the power unit 130 drives the moving seat 121 to rise until the movement returns to the high position, that is, returns to the initial state before detection.

[0035] Based on the above working principle, the motor rotor gluing quality detection device 100 provided in the embodiment detects the distribution of the rubber strip material 230 along the thickness direction of the rubber strip material 230, and can obtain the length of the rubber strip material 230 at different thicknesses and the actual thickness of the rubber strip material 230. The detection result can reflect the properties of the rubber strip material 230 inside the rotor slot 220, which is conducive to more accurate evaluation of the quality of the rubber strip material 230 formed by gluing.

[0036] See also Figure 1 and Figure 2 In some embodiments, the power unit 130 includes a swing arm 131, a synchronous pulley 132, a first rotating disk 133, and a synchronous belt 134. The swing arm 131 is rotatably connected to a first reference shaft 135 whose axis is parallel to a first direction. The synchronous pulley 132 is rotatably connected to a second reference shaft 136 whose axis is parallel to the first direction. The first rotating disk 133 is fixedly connected to a drive shaft 137 whose axis is parallel to the first direction. The first and second reference shafts 135, 136 are illustratively fixed to the device base, and the drive shaft 137 is illustratively connected to the output shaft of the rotating motor. In the vertical direction, the second reference shaft 136 is higher than the first reference shaft 135 and the drive shaft 137. In the horizontal direction, the first reference shaft 135, the second reference shaft 136, and the drive shaft 137 are arranged in sequence.

[0037] Wherein, a first connecting seat 1311 is provided on the side wall of a section of the swing arm 131 close to the first reference axis 135; the first connecting seat 1311 is exemplarily rotatably connected to the main body of the swing arm 131, and the axial direction of rotation is parallel to the first direction. A second connecting seat 1331 is eccentrically provided on the disk surface of the first rotating disk 133, and the second connecting seat 1331 is exemplarily rotatably connected to the disk surface of the first rotating disk 133, and the axial direction of rotation is parallel to the first direction. The synchronous belt 134 is slidably matched with the synchronous pulley 132. The synchronous belt 134 can be in the form of a rope-shaped strip, a flat belt, etc. One end of the synchronous belt 134 is connected to the first connecting seat 1311, and the other end of the synchronous belt 134 is connected to the second connecting seat 1331.

[0038] See Figure 7 , a sliding cavity 1312 extending along the length direction of the swing arm 131 is formed inside a section of the swing arm 131 away from the first reference axis 135. A sliding block 1313 is slidably arranged in the sliding cavity 1312, and the sliding block 1313 can slide in the sliding cavity 1312 along the length direction of the arm. The sliding block 1313 is rotatably connected to the moving seat 121 so that the power unit 130 is in transmission connection with the moving seat 121.

[0039] Based on the technical solution of configuring the swing arm 131 and other structures as described above, its working principle is as follows: In the initial state without detection, see Figure 1 , the moving seat 121 is at a high position, and at this time, the second connecting seat 1331 moves to a position below the driving shaft 137 and is at the lowest position.

[0040] During detection, when the driving shaft 137 rotates, before the second connecting seat 1331 rotates to the highest position, the second connecting seat 1331 gradually rises. At this time, the synchronous belt 134 slides on the synchronous pulley 132 in the direction close to the first connecting seat 1311, and the first connecting seat 1311 and the swing arm 131 swing downward around the first reference axis 135 under the action of gravity; exemplarily, a torsion spring for driving the first reference axis 135 to swing downward is connected between the first connecting seat 1311 and the swing arm 131, making the process of the swing arm 131 swinging downward smoother. Since the moving seat 121 can only move up and down in the vertical direction and the sliding block 1313 is rotatably matched with the moving seat 121, during the downward swing of the swing arm 131, the sliding block 1313 slides in the length direction of the swing arm 131 in the direction close to the first reference axis 135 and rotates relative to the moving seat 121. The height of the sliding block 1313 in the vertical direction decreases and drives the moving seat 121 to descend. Until the second connecting seat 1331 moves to the highest position, see Figure 2 , at this time, the swing arm 131 swings to the lowest position, and the sliding block 1313 drives the moving seat 121 to descend to this low position.

[0041] After the detection is completed, the drive shaft 137 continues to rotate. Before the second connecting seat 1331 moves back to the lowest position, the second connecting seat 1331 gradually descends. At this time, the synchronous belt 134 slides on the synchronous pulley 132 in the direction approaching the second connecting seat 1331. The first connecting seat 1311 and the swing arm 131 swing upward around the first reference axis 135 under the traction of the synchronous belt 134. During the upward swing of the swing arm 131, the sliding block 1313 slides along the length direction of the swing arm 131 in the direction away from the first reference axis 135 and rotates relative to the moving seat 121. The height of the sliding block 1313 in the vertical direction increases and drives the moving seat 121 to rise. Until the second connecting seat 1331 moves back to the lowest position, see Figure 1 , at this time the swing arm 131 swings to the highest position, and the sliding block 1313 drives the moving seat 121 to rise to this high position, that is, it returns to the initial state before detection.

[0042] Based on the above working principle, in the technical solution of configuring the swing arm 131 and other structures, the rotation of the drive shaft 137 drives the eccentrically arranged second connecting seat 1331 to move, so that the synchronous belt 134 connected to the second connecting seat 1331 drives the swing arm 131 to swing, thereby driving the moving seat 121 to move up and down. In this driving mode, the drive shaft 137 rotates one week to realize one reciprocating movement of the up and down movement of the moving seat 121, which is convenient to drive; and the rotation power drives the up and down movement, with high movement smoothness and high adjustment accuracy.

[0043] See Figures 8 - 12 , in some implementation schemes, a storage cavity 1211 with an open bottom is provided in the moving seat 121. The body of the moving seat 121 is rotatably provided with a transmission shaft 1212 located in the storage cavity 1211. The transmission shaft 1212 is fixedly connected to the sliding block 1313 so that the body of the moving seat 121 is rotatably connected to the sliding block 1313. The transmission shaft 1212 is used to realize the relative rotation between the body of the moving seat 121 and the sliding block 1313 when the swing arm 131 swings. The axial direction of the transmission shaft 1212 is parallel to the axial direction of the first reference axis 135.

[0044] Both ends of the transmission shaft 1212 are respectively connected with transmission gears 1213, and the two transmission gears 1213 respectively correspond to the two detection brackets 122. A transmission rack 1221 extending in the vertical direction is provided on the side wall of the detection bracket 122. The transmission gear 1213 meshes with the transmission rack 1221 so that when the moving seat 121 moves to a high position, the detection bracket 122 drives the distance sensor 123 to retract into the storage cavity 1211, and when the moving seat 121 moves to a low position, the detection bracket 122 drives the distance sensor 123 to extend out of the storage cavity 1211 from the bottom of the moving seat 121.

[0045] In the above technical solution, the transmission gear 1213 of the moving seat 121 meshes with the transmission rack 1221 of the detection bracket 122, and its working principle is as follows: In the initial state without detection, refer to Figure 1 and Figures 8 - 10 , the swing arm 131 is in the raised state, and the detection bracket 122 and the distance sensor 123 are located in the storage cavity 1211.

[0046] During detection, the swing arm 131 swings downward, driving the sliding block 1313 and the transmission shaft 1212 to rotate relative to the body of the moving seat 121 in the first rotation direction ( Figure 10 taking the clockwise direction as an example in Figure 11 and Figure 12 ), the transmission shaft 1212 drives the transmission gear 1213 to rotate in the first rotation direction, and the rotation of the transmission gear 1213 causes the transmission rack 1221 to drive the detection bracket 122 to extend out of the storage cavity 1211 from the bottom of the moving seat 121; until the swing arm 131 swings to the lowest position, the detection bracket 122 stops descending, refer to

[0047] and Figure 11 and Figure 12 Figure 12 ), at this time, the detection bracket 122 drives the distance sensor 123 to extend out of the storage cavity 1211 from the bottom of the moving seat 121.

[0048] Based on the above working principle, in the above technical solution, a transmission gear 1213 that rotates synchronously with the sliding block 1313 is configured on the body of the moving seat 121, and a transmission rack 1221 is correspondingly configured on the detection bracket 122. During the process of the drive shaft 137 outputting power to drive the moving seat 121 to lift and lower, the relative rotation between the body of the moving seat 121 and the sliding block 1313 can be utilized to make the transmission gear 1213 drive the transmission rack 1221. Among them, in the initial state without detection, the detection bracket 122 and the distance sensor 123 are located in the storage cavity 1211, which can effectively prevent dust; moreover, during the process of the drive shaft 137 outputting power to drive the moving seat 121 to lift and lower, the telescopic drive of the detection bracket 122 can be realized synchronously, and only one power source needs to be configured, with better controllability.

[0049] See Figure 7 Figure 7 , in some embodiments, an air vent cavity 1314 extending along the length direction of the swing arm 131 is further formed inside a section of the swing arm 131 away from the first reference axis 135. The air vent cavity 1314 is located on a side of the sliding cavity 1312 away from the first reference axis 135. An air vent piston 1315 is slidably disposed in the air vent cavity 1314. The air vent piston 1315 and the sliding block 1313 are connected by a piston rod 1316. Wherein, on a side of the air vent piston 1315 close to the first reference axis 135, the air vent cavity 1314 communicates with the outside. The air vent piston 1315 is provided with a one-way air intake structure 13151 to enable gas to intake unidirectionally from the side close to the first reference axis 135 towards the side away from the first reference axis 135. The swing arm 131 is provided with an air outlet 1317, and a one-way air outlet structure 13171 is disposed in the air outlet 1317 to enable gas to be discharged outwards from the air outlet 1317 unidirectionally. On a side of the air vent piston 1315 away from the first reference axis 135, the air vent cavity 1314 communicates with the air outlet 1317. It can be understood that the one-way air intake structure 13151 and the one-way air outlet structure 13171 can be conventionally designed, for example, but not limited to, being configured in the form of a one-way valve flap or a one-way valve.

[0050] See Figure 10 and Figure 12 Figure 12 , an air vent passage 1222 is provided on the inner side surface of the detection bracket 122. As an example, a protruding portion is provided on the inner side surface of the detection bracket 122, and the air vent passage 1222 penetrates through the protruding portion in the vertical direction. The air inlet and the air outlet 1317 of the air vent passage 1222 are connected by an air vent hose (not shown in the figure), and the air outlet 1317 of the air vent passage 1222 opens downward and is located above the distance sensor 123.

[0051] The working principle of the above technical solution is as follows: During detection, when the drive shaft 137 outputs power to drive the moving seat 121 to descend, the swing arm 131 swings downward, the sliding block 1313 slides along the length direction of the swing arm 131 towards the direction close to the first reference axis 135. The sliding block 1313 drives the piston rod 1316, and the piston rod 1316 drives the air vent piston 1315 away from the air outlet 1317. The air pressure in the air vent cavity 1314 is less than the atmospheric pressure, causing the one-way air intake structure 13151 to open, and external gas enters the side of the air vent piston 1315 close to the first reference axis 135. Until the moving seat 121 stops moving and the air intake reaches air pressure balance, the one-way air intake structure 13151 returns to the closed state.

[0052] After the detection is completed, during the process of the drive shaft 137 outputting power to drive the moving seat 121 to rise, the swing arm 131 swings upward, the sliding block 1313 slides along the length direction of the swing arm 131 in a direction away from the first reference axis 135, the sliding block 1313 drives the piston rod 1316, and the piston rod 1316 drives the ventilation piston 1315 to approach the air outlet 1317. The air pressure in the ventilation chamber 1314 is greater than the atmospheric pressure, causing the one-way air outlet structure 13171 to open. At this time, air can be blown into the ventilation duct 1222 through the ventilation hose. After the air enters the ventilation duct 1222, it blows downward from above the distance sensor 123; until the moving seat 121 stops moving and the exhaust reaches air pressure balance, the one-way air outlet structure 13171 returns to the closed state, and the ventilation duct 1222 stops blowing downward from above the distance sensor 123.

[0053] Based on the above working principle, in the above technical solution, during the process of the drive shaft 137 outputting power to drive the moving seat 121 to rise, the sliding of the sliding block 1313 can be used to push the ventilation piston 1315 to supply air to the ventilation duct 1222 of the detection bracket 122. The ventilation duct 1222 blows downward from above the distance sensor 123, which can remove dust on the surface of the distance sensor 123, and is beneficial to protecting the distance sensor 123 to obtain more accurate detection results.

[0054] Continue to refer to Figure 10 and Figure 12 Moreover, on the inner side of the bottom of the detection bracket 122, there is also a guiding convex block 1223. The guiding convex block 1223 is located below the distance sensor 123, and on the side of the guiding convex block 1223 close to the distance sensor 123, there is an arc-shaped guiding surface with ferromagnetism. It can be understood that the guiding convex block 1223 can be a magnet as a whole, or an arc-shaped surface layer made of magnet material can be provided on the side of the guiding convex block 1223 close to the distance sensor 123.

[0055] Based on the above design, when the ventilation duct 1222 blows downward from above the distance sensor 123, the arc-shaped guiding surface can guide the blown dust to the side below the distance sensor 123, avoiding the accumulation of the blown dust to form dead corners; in addition, due to the ferromagnetism of the arc-shaped guiding surface, during detection, it can adsorb and remove ferromagnetic dust in the rotor slot 220.

[0056] Refer to Figure 9 、 Figure 11 and Figure 13, the motor rotor glue application quality detection device 100 further includes a dust collection unit 140; a collection channel 1214 communicating with the storage cavity 1211 is further provided in the moving seat 121, and the outlet of the collection channel 1214 communicates with the dust collection unit 140. When the moving seat 121 is at a high position, an air vent gap communicating with the collection channel 1214 is formed between the inner side surface of the detection bracket 122 and the body of the moving seat 121; the air outlet 1317 of the air vent passage 1222 corresponds to the upper opening of the air vent gap, wherein the air outlet 1317 of the air vent passage 1222 can be aligned with the upper opening of the air vent gap, or can be slightly higher or slightly lower than the upper opening of the air vent gap; the inlet of the collection channel 1214 is aligned with the arc-shaped guiding surface.

[0057] Based on the above design, when the detection bracket 122 rises to be close to Figure 11 After reaching the highest position shown, as the detection bracket 122 continues to rise, the gas blown out by the air vent passage 1222 first passes through the air vent gap and blows towards the arc-shaped guiding surface, and then is guided towards the collection channel 1214 through the arc-shaped guiding surface. Since the cross-sectional area of the air vent gap is relatively small, the gas has a relatively high flow rate, which is beneficial to blowing the ferromagnetic dust adsorbed on the arc-shaped guiding surface into the collection channel 1214 more thoroughly; since the cross-sectional area of the collection channel 1214 is relatively small, the gas has a relatively high flow rate, which is beneficial to blowing the dust in the collection channel 1214 into the dust collection unit 140.

[0058] Refer to Figure 13 , exemplarily, the dust collection unit 140 includes a dust collection chamber 141, a camera 142 and a filter plate 143. Optionally, the inlet of the dust collection chamber 141 is opened at the top of the dust collection chamber 141, and the outlet of the dust collection chamber 141 is opened at the bottom of the dust collection chamber 141. The inlet of the dust collection chamber 141 communicates with the outlet of the collection channel 1214; the filter plate 143 is installed in the dust collection chamber 141, and the inlet and outlet of the dust collection chamber 141 are respectively located on both sides of the filter plate 143; the camera 142 is installed in the dust collection chamber 141, and the lens of the camera 142 faces the filter plate 143. Optionally, a transparent partition is provided around the front of the lens of the camera 142, and the transparent partition is used to separate the camera 142 from the internal cavity of the dust collection chamber 141 to prevent the dust entering the dust collection chamber 141 from adhering to or scratching the camera 142.

[0059] In the above technical solution, the dust collected by the dust collection chamber 141 is intercepted by the filter plate 143, and the adhesion condition of the dust on the filter plate 143 is observed through the camera 142, so as to analyze the dust collection speed of the dust collection chamber 141. When the dust collection speed of the dust collection chamber 141 is relatively fast, it indicates that the dust amount in the working environment is relatively high. At this time, the working environment can be dust-removed, which is beneficial to maintaining a clean working environment.

[0060] Refer to Figure 3 and Figures 14 - 17, in some embodiments, the power unit 130 further includes a second rotating disk 138, which is fixedly connected to the drive shaft 137. The second rotating disk 138 is exemplarily located on a side of the first rotating disk 133 where the second connecting seat 1331 is not provided. On a disk surface of the second rotating disk 138 away from the first rotating disk 133, there are spaced-apart limiting bumps 1381 and transmission columns 1382. On a side of the limiting bump 1381 away from the transmission column 1382, there is an arc-shaped guiding edge 13811 coaxial with the second rotating disk 138. The distance from the transmission column 1382 to the axis of the drive shaft 137 is greater than the radius of the arc-shaped guiding edge 13811.

[0061] The bracket unit 110 further includes a rotating shaft fixing turntable 113, which is rotatably connected to the top of a support member 112. The axial direction of the rotating shaft fixing turntable 113 is the first direction. On the disk surface of the rotating shaft fixing turntable 113, there is a rotating shaft fixing groove 1131 matching the rotor rotating shaft 210. During operation, a rotor rotating shaft 210 of the motor rotor 200 can be inserted and fixed in the rotating shaft fixing groove 1131. By the rotation of the rotating shaft fixing turntable 113, the motor rotor 200 is driven to rotate, so as to switch the rotor slots 220 of the motor rotor 200 facing upward, and further switch the target rubber strip material 230 to be detected. Based on this, optionally, a support groove can be configured at the top of the other support member 112, and the other rotor rotating shaft 210 of the motor rotor 200 can be rotatably received in the support groove.

[0062] On the edge of the rotating shaft fixing turntable 113, there are a plurality of arc-shaped limiting grooves 1132 and a plurality of transmission chutes 1133. The numbers of the arc-shaped limiting grooves 1132 and the transmission chutes 1133 are respectively exemplarily the same as the number of the rotor slots 220 of the rotor rotating shaft 210. The plurality of arc-shaped limiting grooves 1132 are evenly spaced along the circumferential direction of the rotating shaft fixing turntable 113, and the plurality of transmission chutes 1133 are evenly spaced along the circumferential direction of the rotating shaft fixing turntable 113. The arc-shaped limiting grooves 1132 and the rotating shaft fixing groove 1131 are arranged alternately. That is to say, in the circumferential direction of the rotating shaft fixing turntable 113, they are arranged alternately in the order of one arc-shaped limiting groove 1132, then one transmission chute 1133, then one arc-shaped limiting groove 1132, and then one transmission chute 1133. The arc-shaped limiting groove 1132 matches the arc-shaped guiding edge 13811, and the transmission chute 1133 extends from the edge of the rotating shaft fixing turntable 113 towards the axis of the rotating shaft fixing turntable 113.

[0063] See Figure 14, when the distance sensor 123 is located in the rotor slot 220, at least a part of the arc-shaped guiding edge 13811 fits with the arc-shaped limiting groove 1132, and the transmission column 1382 is located outside the transmission sliding groove 1133. It should be noted that the transmission column 1382 being located outside the transmission sliding groove 1133 does not mean that the transmission column 1382 is located at the opening of the transmission sliding groove 1133, but rather indicates that the transmission column 1382 is not engaged with the transmission sliding groove 1133. In this state, the cooperation between the arc-shaped guiding edge 13811 and the arc-shaped limiting groove 1132 limits the rotation of the rotating shaft-fixed turntable 113 to prevent the rotating shaft-fixed turntable 113 from driving the motor rotor 200 to rotate, and the distance sensor 123 can more conveniently and accurately detect the rubber strip material 230 in the rotor slot 220. After the detection is completed, during the process of the drive shaft 137 driving the moving seat 121 to rise through the rotation of the first rotating disk 133, the second rotating disk 138 rotates synchronously. At this time, the arc-shaped guiding edge 13811 gradually slides out from the sliding-out side of the arc-shaped limiting groove 1132 that it cooperates with.

[0064] Taking the clockwise rotation of the second rotating disk 138 as an example, during the process of the arc-shaped guiding edge 13811 sliding out from the sliding-out side of the arc-shaped limiting groove 1132, refer to Figure 15 , when the arc-shaped guiding edge 13811 slides past the center of the arc-shaped limiting groove 1132, the transmission column 1382 first reaches the opening of the transmission sliding groove 1133 on the sliding-in side of the arc-shaped limiting groove 1132; as the second rotating disk 138 continues to rotate, the transmission column 1382 slides into the transmission sliding groove 1133 on the sliding-in side of the arc-shaped limiting groove 1132. After the transmission column 1382 slides into the transmission sliding groove 1133, as the second rotating disk 138 continues to rotate, the arc-shaped guiding edge 13811 gradually slides out from the sliding-out side of the arc-shaped limiting groove 1132 that it cooperates with and finally disengages from the arc-shaped limiting groove 1132, and at the same time, the transmission column 1382 drives the rotating shaft-fixed turntable 113 to rotate in the direction opposite to that of the second rotating disk 138; refer to Figure 16 , the transmission column 1382 first gradually slides towards the bottom of the transmission sliding groove 1133 until it slides to the bottom of the transmission sliding groove 1133; refer to Figure 17 , then the transmission column 1382 gradually slides towards the opening of the transmission sliding groove 1133 until it disengages from the rotating shaft-fixed turntable 113 from the opening of the transmission sliding groove 1133.

[0065] Continue to refer to Figure 16 and Figure 17, during the process of the transmission column 1382 sliding out of the transmission chute 1133, the arc-shaped guiding edge 13811 slides into the sliding-in side of the next arc-shaped limiting groove 1132. After the transmission column 1382 detaches from the rotating shaft fixing turntable 113 at the opening of the transmission chute 1133, the cooperation between the arc-shaped guiding edge 13811 and the arc-shaped limiting groove 1132 limits the rotating shaft fixing turntable 113 until the second rotating disc 138 further rotates and returns to the state as shown in Figure 14 shown.

[0066] It can be understood that the distribution range of the limiting bumps 1381 (such as the central angle corresponding to), the distance from the transmission column 1382 to the axis of the drive shaft 137, the depth of the transmission chute 1133, etc. can be correspondingly configured based on the above relative position relationship.

[0067] In the above technical solution, by configuring the mutually cooperating rotating shaft fixing turntable 113 and the second rotating disc 138, when the drive shaft 137 outputs power to drive the moving seat 121 to rise, it can also drive the second rotating disc 138 to drive the rotating shaft fixing turntable 113 to rotate. By rotating the rotating shaft fixing turntable 113 to switch the upward-facing strip material 230 as the measurement target, compared with separately configuring the power drive motor rotor 200 to rotate, this design method is more convenient to operate.

[0068] See Figure 18 , in some further embodiments, the rotating shaft fixing turntable 113 is further provided with a rotating shaft fixing sleeve 1134 located in the rotating shaft fixing groove 1131. The rotating shaft fixing sleeve 1134 is used for plugging and fixing the rotor rotating shaft 210; the rotating shaft fixing sleeve 1134 is rotatably matched with the rotating shaft fixing groove 1131 within a preset angle; that is to say, the rotating shaft fixing sleeve 1134 can drive the motor rotor 200 to rotate relative to the rotating shaft fixing groove 1131 within a preset angle.

[0069] Optionally, the preset angle is a relatively small angle, such as <10°, further <5°. Exemplarily, in the cross-section of the rotating shaft fixing sleeve 1134 and the rotating shaft fixing groove 1131, the main body part is circular; on a part of the circular main body, there are outwardly protruding fan-shaped ears. Among them, the central angle corresponding to the fan-shaped ear of the rotating shaft fixing sleeve 1134 is smaller than the central angle corresponding to the fan-shaped ear of the rotating shaft fixing groove 1131, and the difference between the two is the preset angle, so that the rotating shaft fixing sleeve 1134 can rotate relative to the rotating shaft fixing groove 1131 within a preset angle.

[0070] Based on this design, during inspection, when the inspection bracket 122 extends into the rotor slot 220, if the slot wall of the rotor slot 220 is stained with impurities (such as overflowed glue material), when the impurities come into contact with the inspection bracket 122, the motor rotor 200 can swing within a preset angle range under the action of the inspection bracket 122 on the impurities, thereby preventing the impurities from interfering with the descent of the inspection bracket 122, making the lifting and lowering of the inspection bracket 122 smoother.

[0071] Optionally, the outer wall of the shaft fixing sleeve 1134 and the groove wall of the shaft fixing groove 1131 cooperate in a damping sliding manner so that the two can remain relatively fixed in the absence of external force, and then rotate relative to each other based on the force under the action of the detection bracket 122.

[0072] See also Figure 19 and Figure 20 A gas compression chamber 1135 is also defined within the shaft-fixing turntable 113. This chamber is located on the side of the transmission chute 1133 near the shaft-fixing groove 1131 and illustratively extends radially of the shaft-fixing turntable 113. A gas compression piston 11351 is slidably disposed within the gas compression chamber 1135. A gas compression transmission member 11331 is slidably disposed within the transmission chute 1133. The gas compression transmission member 11331 is in driving connection with the gas compression piston 11351 and cooperates with a transmission post 1382, such that when the transmission post 1382 slides into the transmission chute 1133, the gas compression transmission member 11331 drives the gas compression piston 11351 to slide and compress the gas within the gas compression chamber 1135.

[0073] As an example, the gas compression transmission member 11331 includes a connecting rod, a telescopic spring, and a sliding plate. The sliding plate is slidably connected to the body of the rotating shaft fixed turntable 113 along the depth direction of the transmission chute 1133, and the width of the sliding plate matches that of the transmission column 1382. The connecting rod extends along the depth direction of the transmission chute 1133, the bottom end of the connecting rod is connected to the gas compression piston 11351, and the rod body of the connecting rod is slidably disposed through the sliding plate; the telescopic spring is sleeved on the connecting rod, and the telescopic spring abuts between the sliding plate and the gas compression piston 11351. Based on this, when the transmission column 1382 slides into the transmission chute 1133, during the process of the transmission column 1382 sliding towards the bottom of the transmission chute 1133, the transmission column 1382 drives the sliding plate to slide towards the bottom of the transmission chute 1133, the sliding plate compresses the telescopic spring, and the telescopic spring drives the gas compression piston 11351 to slide towards the direction close to the bottom of the gas compression chamber 1135, and the gas in the gas compression chamber 1135 is compressed during the sliding process; during the process of the transmission column 1382 sliding from the bottom of the transmission chute 1133 towards the opening, the telescopic spring exerts a force on the sliding plate to make the sliding plate slide from the bottom of the transmission chute 1133 towards the opening and return to the initial position. At the same time, the action of the telescopic spring on the gas compression piston 11351 decreases, and under the action of the air pressure in the gas compression chamber 1135, the gas compression piston 11351 slides towards the direction close to the transmission chute 1133 and returns to the initial position.

[0074] A pressing piston 11311 and a pressing plate 11312 are provided in the rotating shaft fixing groove 1131. The pressing plate 11312 is connected to the side of the pressing piston 11311 close to the rotating shaft fixing sleeve 1134. The bottom of the rotating shaft fixing groove 1131 communicates with the gas compression chamber 1135, so that when the gas in the gas compression chamber 1135 is compressed, the pressing piston 11311 slides towards the side close to the rotating shaft fixing sleeve 1134 and drives the pressing plate 11312 to press the rotating shaft fixing sleeve 1134.

[0075] In the state where the transmission column 1382 cooperates with the transmission chute 1133, it is in the process of the rotating motor rotor 200 switching the test strip material 230. Based on this design, during the process of the rotating motor rotor 200 switching the test strip material 230, through the cooperation of the transmission column 1382 and the transmission chute 1133, the pressing plate 11312 can exert a pressing effect on the rotating shaft fixing sleeve 1134, so that the rotating shaft fixing sleeve 1134 and the rotating shaft fixing groove 1131 can better maintain relative fixation, thereby making the rotation angle of the motor rotor 200 more accurate.

[0076] As an example, the pressing piston 11311 and the pressing plate 11312 are connected by a connecting shaft. A return spring is sleeved outside the connecting shaft, and the return spring abuts between the body of the rotating shaft fixed turntable 113 and the pressing piston 11311. After the transmission column 1382 slides out of the opening of the transmission chute 1133, the return spring pushes the pressing piston 11311 to move back towards the bottom of the rotating shaft fixing groove 1131.

[0077] In a second aspect, an embodiment of the present application provides an automated motor assembly system (not shown in the figure), including the motor rotor glue injection quality detection device 100 provided in the above embodiment.

[0078] In the present application, the automated motor assembly system can be provided with other functional devices according to conventional requirements. For example, but not limited to, a feeding device can be configured upstream of the motor rotor glue injection quality detection device 100, a glue sealing device for injecting glue into the rotor groove 220, etc. For example, but not limited to, a discharging device and a sorting device can be configured downstream of the motor rotor glue injection quality detection device 100.

[0079] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
