Description

Technical Field

[0001] The present application relates to the technical field of material testing, and in particular to a motor rotor gluing quality testing device and an automated motor assembly system. Background Art

[0002] Motor rotor gluing is a key process in motor manufacturing. In some processes, glue is applied in the rotor slots to form rubber strips, which are used to fix magnetic steel, provide insulation protection, optimize heat dissipation, and improve the overall stability of the rotor.

[0003] At present, the quality of the rubber strip material formed by gluing is usually evaluated by inspectors observing the surface of the rubber strip material. This method relies on manual labor and has low detection efficiency. The test results cannot reflect the properties of the rubber strip material inside the rotor slot, which is not conducive to accurately evaluating the quality of the rubber strip material formed by gluing. Summary of the Invention

[0004] The purpose of this application is to provide a motor rotor gluing quality detection device and an automated motor assembly system, which uses automatic detection by the detection device to achieve high detection efficiency. During detection, the distribution of the rubber strip material is detected along the thickness direction of the rubber strip material. The detection results can reflect the properties of the rubber strip material inside the rotor slot, which is conducive to more accurate evaluation of the quality of the rubber strip material formed by gluing.

[0005] The embodiment of the present application is implemented as follows:

[0062] The technical solution of this application will be exemplarily described below through some embodiments.

[0063] See also Figure 1 and Figure 2 In a first aspect, an embodiment of the present application provides a motor rotor gluing quality detection device 100 , comprising a bracket unit 110 , a detection unit 120 and a power unit 130 .

[0064] It should be noted that in the embodiments of the present application, in addition to the above-mentioned functional units, the motor rotor gluing quality inspection device 100 can also be conventionally configured with a device base, which can be in the form of a casing, a frame, etc. In the absence of a limit on the fixing method of a specific functional structure, the specific functional structure can be fixed to the ground, a wall or the device base, for example.

[0065] See also Figure 3 and Figure 4The bracket unit 110 includes a bracket base 111 and two support members 112. The bracket base 111 can be fixed to the ground or to the base of the device. The two support members 112 are spaced apart at the top of the bracket base 111 along a first direction, which is consistent with the axial direction of the motor rotor 200. The bottom of the support member 112 is fixedly connected to the bracket base 111 for example. 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; the top of the support member 112 can also be connected to a sleeve for plugging and fixing the rotor shaft 210.

[0066] See also Figure 5 and Figure 6 The 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.

[0067] 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 6When 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.

[0068] The motor rotor gluing quality detection device 100 provided in the embodiment of the present application has the following working principles:

[0069] 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.

[0070] 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 6 When 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.

[0071] 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.

[0072] 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.

[0073] See also Figure 1 and Figure 2In 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.

[0074] A first connecting seat 1311 is provided on the side wall of a section of the swing arm 131 near 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 axis of rotation is parallel to the first direction. A second connecting seat 1331 is eccentrically provided on the surface of the first rotating disk 133. The second connecting seat 1331 is exemplarily rotatably connected to the surface of the first rotating disk 133, and the axis of rotation is parallel to the first direction. The synchronous belt 134 is slidably engaged with the synchronous wheel 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.

[0075] See also Figure 7 A sliding cavity 1312 extending along the length of the swing arm 131 is defined within a portion of the swing arm 131 away from the first reference axis 135. A sliding block 1313 is slidably disposed within the sliding cavity 1312. The sliding block 1313 is rotatably connected to the moving base 121, thereby providing a transmission connection between the power unit 130 and the moving base 121.

[0076] Based on the above technical solution of configuring the swing arm 131 and other structures, the working principle is as follows:

[0077] In the unchecked initial state, see Figure 1 , the moving seat 121 is located at a high position, and at this time the second connecting seat 1331 moves to the bottom of the driving shaft 137 and is located at the lowest position.

[0078] During testing, the drive shaft 137 rotates, and before the second connecting seat 1331 rotates to its highest position, the second connecting seat 1331 gradually rises. At this time, the synchronous belt 134 slides on the synchronous wheel 132 toward 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. For example, a torsion spring is connected between the first connecting seat 1311 and the swing arm 131 to drive the first reference axis 135 to swing downward, making the swing arm 131 swing downward more smoothly. Since the moving seat 121 can only be raised and lowered in the vertical direction and the sliding block 1313 is rotatably matched with the moving seat 121, during the swing arm 131 downward swing process, the sliding block 1313 slides along the length direction of the swing arm 131 toward the direction close to the first reference axis 135 and rotates relative to the moving seat 121, the sliding block 1313 is lowered in the vertical direction 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 the lower position.

[0079] 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 lowers. At this time, the synchronous belt 134 slides on the synchronous wheel 132 in the direction close to 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 sliding block 1313 increases in height in the vertical direction 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 the high position, that is, it returns to the initial state without detection.

[0080] Based on the aforementioned operating principle, in the technical solution configured with swing arm 131 and other structures, the rotation of drive shaft 137 drives the movement of eccentrically positioned second connecting seat 1331, causing synchronous belt 134 connected to second connecting seat 1331 to swing swing arm 131, thereby driving the movement seat 121 to rise and fall. In this drive mode, one rotation of drive shaft 137 completes one reciprocating movement of the movement seat 121, providing convenient driving. Furthermore, the rotational power drives the movement, resulting in smooth movement and high control precision.

[0081] See also Figures 8 to 12In some embodiments, a bottom-open receiving chamber 1211 is provided within the moving base 121. A transmission shaft 1212 is rotatably disposed within the body of the moving base 121, located within the receiving chamber 1211. The transmission shaft 1212 is fixedly connected to the sliding block 1313, thereby rotatably connecting the body of the moving base 121 to the sliding block 1313. The transmission shaft 1212 is used to achieve relative rotation between the body of the moving base 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.

[0082] Transmission gears 1213 are connected to both ends of the transmission shaft 1212, and the two transmission gears 1213 correspond to the two detection brackets 122. A transmission rack 1221 extending vertically is provided on the sidewall of the detection bracket 122. The transmission gears 1213 mesh with the transmission rack 1221, so that when the moving base 121 moves upward, the detection bracket 122 drives the distance sensor 123 to retract into the storage chamber 1211. When the moving base 121 moves downward, the detection bracket 122 drives the distance sensor 123 to extend from the bottom of the moving base 121 out of the storage chamber 1211.

[0083] In the above technical solution, the transmission gear 1213 of the moving seat 121 is engaged with the transmission rack 1221 of the detection bracket 122, and its working principle is as follows:

[0084] In the unchecked initial state, see Figure 1 and Figures 8 to 10 , the swing arm 131 is in an upward state, and the detection bracket 122 and the distance sensor 123 are located in the storage cavity 1211.

[0085] 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 along the first rotation direction ( Figure 10 The transmission shaft 1212 drives the transmission gear 1213 to rotate along the first rotation direction. 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 base 121; until the swing arm 131 swings to the lowest position, the detection bracket 122 stops descending. Figure 11 and 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.

[0086] See also Figure 11 and Figure 12 After the detection is completed, the swing arm 131 swings upward, driving the sliding block 1313 and the transmission shaft 1212 to rotate relative to the body of the moving seat 121 in a second rotation direction opposite to the first rotation direction ( Figure 12The transmission shaft 1212 drives the transmission gear 1213 to rotate in the second rotation direction. The rotation of the transmission gear 1213 causes the transmission rack 1221 to drive the detection bracket 122 to move upward until the swing arm 131 swings to the highest position. At this time, the detection bracket 122 drives the distance sensor 123 to retract into the receiving chamber 1211, that is, it returns to the initial state without detection.

[0087] 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 main body of the moving seat 121, and a transmission rack 1221 is correspondingly configured on the detection bracket 122. When the drive shaft 137 outputs power to drive the moving seat 121 up and down, it can utilize the relative rotation between the main body of the moving seat 121 and the sliding block 1313 to enable the transmission gear 1213 to drive the transmission rack 1221. Specifically, in the initial state without detection, the detection bracket 122 and the distance sensor 123 are located in the storage chamber 1211, which can effectively prevent dust. Moreover, when the drive shaft 137 outputs power to drive the moving seat 121 up and down, it can simultaneously realize the telescopic drive of the detection bracket 122. Only one power source is required, which improves controllability.

[0088] See also Figure 7 In some embodiments, a ventilation cavity 1314 extending along the length direction of the swing arm 131 is further provided inside a section of the swing arm 131 away from the first reference axis 135. The ventilation cavity 1314 is located on the side of the sliding cavity 1312 away from the first reference axis 135. A ventilation piston 1315 is slidably provided in the ventilation cavity 1314. The ventilation piston 1315 and the sliding block 1313 are connected by a piston rod 1316. Particularly, on the side of the ventilation piston 1315 close to the first reference axis 135, the ventilation cavity 1314 is connected to the outside. The vent piston 1315 is provided with a one-way air inlet structure 13151, allowing air to be unidirectionally inhaled from the side closer to the first reference axis 135 toward the side farther from the first reference axis 135. The swing arm 131 is provided with an air outlet 1317, which is provided with a one-way air outlet structure 13171, allowing air to be discharged unidirectionally from the air outlet 1317. On the side of the vent piston 1315 farther from the first reference axis 135, the vent cavity 1314 is connected to the air outlet 1317. It will be understood that the one-way air inlet structure 13151 and the one-way air outlet structure 13171 can be of conventional design, such as, but not limited to, a one-way valve or a one-way valve.

[0089] See also Figure 10 and Figure 12The inner side of the detection bracket 122 is provided with an air duct 1222. For example, the inner side of the detection bracket 122 is provided with a protrusion, and the air duct 1222 vertically penetrates the protrusion. The air inlet and outlet 1317 of the air duct 1222 are connected by a ventilation hose (not shown). The air outlet 1317 of the air duct 1222 opens downward and is located above the distance sensor 123.

[0090] The working principle of the above technical solution is as follows:

[0091] During the inspection, when the driving shaft 137 outputs power to drive the moving seat 121 to descend, the swing arm 131 swings downward, and the sliding block 1313 slides along the length direction of the swing arm 131 toward 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 ventilation piston 1315 away from the air outlet 1317. The air pressure in the ventilation chamber 1314 is lower than the atmospheric pressure, so that the one-way air intake structure 13151 opens, and external air enters the side of the ventilation 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.

[0092] After the detection is completed, in the process of the drive shaft 137 outputting power to drive the moving seat 121 to rise, the swing arm 131 swings upward, and the sliding block 1313 slides along the length direction of the swing arm 131 toward the direction away from the first reference axis 135, and 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, so that the one-way air outlet structure 13171 is opened. At this time, air can be blown into the air duct 1222 through the ventilation hose. After the gas enters the air duct 1222, it is blown downward from the top of 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 air duct 1222 stops blowing air downward from the top of the distance sensor 123.

[0093] Based on the above working principle, in the above technical solution, when the driving shaft 137 outputs power to drive the moving seat 121 to rise, the sliding block 1313 can be used to slide the ventilation piston 1315 to supply air to the air duct 1222 of the detection bracket 122. The air duct 1222 blows downward from the top of the distance sensor 123, which can remove dust from the surface of the distance sensor 123, which is beneficial to protect the distance sensor 123 to obtain more accurate detection results.

[0094] Continue to see Figure 10 and Figure 12Furthermore, a guide protrusion 1223 is provided on the inner side of the bottom of the detection bracket 122. The guide protrusion 1223 is located below the distance sensor 123. A ferromagnetic arc-shaped guide surface is provided on the side of the guide protrusion 1223 close to the distance sensor 123. It is understood that the guide protrusion 1223 can be entirely magnetized, or a magnetic arc-shaped surface layer can be provided on the side of the guide protrusion 1223 close to the distance sensor 123.

[0095] Based on the above design, when the air duct 1222 blows air downward from the top of the distance sensor 123, the arc-shaped guide surface can guide the blown dust to the side below the distance sensor 123 to avoid the accumulation of the blown dust to form a dead corner; in addition, since the arc-shaped guide surface is ferromagnetic, it can absorb and remove ferromagnetic dust in the rotor slot 220 during detection.

[0096] See also Figure 9 、 Figure 11 and Figure 13 The motor rotor gluing quality inspection device 100 further includes a dust collection unit 140; a collection channel 1214 communicating with the storage chamber 1211 is further provided in the moving seat 121, and the outlet of the collection channel 1214 is communicated with the dust collection unit 140. When the moving seat 121 is in a high position, a ventilation gap communicating with the collection channel 1214 is formed between the inner side surface of the inspection bracket 122 and the body of the moving seat 121; the air outlet 1317 of the air channel 1222 corresponds to the upper opening of the ventilation gap, wherein the air outlet 1317 of the air channel 1222 can be aligned with the upper opening of the ventilation gap, or slightly higher or slightly lower than the upper opening of the ventilation gap; the inlet of the collection channel 1214 is aligned with the arc-shaped guide surface.

[0097] Based on the above design, when the detection bracket 122 rises to a position close to Figure 11 After reaching the highest position shown, as detection bracket 122 continues to rise, the gas blown out of air passage 1222 first passes through the ventilation gap and is blown toward the curved guide surface, and then is guided through the curved guide surface to collection channel 1214. Because the ventilation gap has a relatively small cross-sectional area, the gas has a high flow rate, which helps to more thoroughly blow the ferromagnetic dust adsorbed on the curved guide surface into collection channel 1214. Because the cross-sectional area of ​​collection channel 1214 is relatively small, the gas has a high flow rate, which helps to blow the dust in collection channel 1214 into dust collection unit 140.

[0098] See also Figure 13Exemplarily, the dust collection unit 140 includes a dust collection chamber 141, a camera 142, and a filter plate 143. Optionally, the entrance 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 entrance of the dust collection chamber 141 is connected to the outlet of the collection channel 1214; the filter plate 143 is installed in the dust collection chamber 141, and the entrance 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 in front of the lens of the camera 142, which is used to separate the camera 142 from the internal cavity of the dust collection chamber 141 to prevent dust entering the dust collection chamber 141 from adhering to or scratching the camera 142.

[0099] In the above technical solution, dust collected in the dust collection chamber 141 is intercepted by the filter plate 143, and the dust adhesion to the filter plate 143 is observed by the camera 142, thereby analyzing the dust collection speed of the dust collection chamber 141. If the dust collection speed of the dust collection chamber 141 is relatively fast, it indicates that the dust content in the working environment is relatively high. In this case, the working environment can be dust-removed to maintain a clean working environment.

[0100] See also Figure 3 and Figures 14 to 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 illustratively located on the side of the first rotating disk 133 where the second connecting seat 1331 is not provided. A surface of the second rotating disk 138, which is away from the first rotating disk 133, is provided with spaced apart limiting protrusions 1381 and a transmission post 1382. The limiting protrusion 1381, which is away from the transmission post 1382, has an arc-shaped guide edge 13811 coaxial with the second rotating disk 138 on the side away from the transmission post 1382. The distance between the transmission post 1382 and the axis of the drive shaft 137 is greater than the radius of the arc-shaped guide edge 13811.

[0101] The bracket unit 110 also includes a shaft fixing turntable 113, which is rotatably connected to the top of one support member 112. The axial direction of the shaft fixing turntable 113 is a first direction, and the disk surface of the shaft fixing turntable 113 is provided with a shaft fixing groove 1131 that matches the rotor shaft 210. During operation, one rotor shaft 210 of the motor rotor 200 can be inserted and fixed in the shaft fixing groove 1131. The rotation of the shaft fixing turntable 113 drives the motor rotor 200 to rotate, thereby switching the rotor slot 220 of the motor rotor 200 facing upward, and then switching the target rubber strip material 230 to be detected. Based on this, optionally, the top of the other support member 112 can be configured with a support groove, and the other rotor shaft 210 of the motor rotor 200 can be rotatably accommodated in the support groove.

[0102] The edge of the shaft-fixing turntable 113 is provided with a plurality of arcuate retaining grooves 1132 and a plurality of transmission slots 1133. The number of arcuate retaining grooves 1132 and transmission slots 1133 is illustratively the same as the number of rotor slots 220 of the rotor shaft 210. The plurality of arcuate retaining grooves 1132 are evenly spaced along the circumference of the shaft-fixing turntable 113, and the plurality of transmission slots 1133 are evenly spaced along the circumference of the shaft-fixing turntable 113. The arcuate retaining grooves 1132 and the shaft-fixing grooves 1131 are arranged alternately. In other words, along the circumference of the shaft-fixing turntable 113, the arrangement is alternating in the order of one arcuate retaining groove 1132, then one transmission slot 1133, then one arcuate retaining groove 1132, and then one transmission slot 1133. The arc-shaped limiting groove 1132 matches the arc-shaped guiding edge 13811 , and the transmission sliding groove 1133 extends from the edge of the shaft-fixing turntable 113 toward the axis of the shaft-fixing turntable 113 .

[0103] See also Figure 14 When distance sensor 123 is located in rotor slot 220, at least a portion of arcuate guide edge 13811 abuts arcuate limiting groove 1132, and transmission post 1382 is located outside transmission slot 1133. It should be noted that transmission post 1382 being located outside transmission slot 1133 does not necessarily mean that transmission post 1382 is located at the opening of transmission slot 1133, but rather indicates that transmission post 1382 is not engaged with transmission slot 1133. In this state, the engagement between arcuate guide edge 13811 and arcuate limiting groove 1132 limits the position of shaft fixing turntable 113, preventing shaft fixing turntable 113 from driving motor rotor 200 to rotate. This allows distance sensor 123 to more conveniently and accurately detect rubber strip material 230 in rotor slot 220. After the detection is completed, the driving shaft 137 drives the moving seat 121 to rise through the rotation of the first rotating disk 133, and the second rotating disk 138 rotates synchronously. At this time, the arc-shaped guiding edge 13811 gradually slides out from the sliding side of the arc-shaped limiting groove 1132 that cooperates with it.

[0104] Taking the clockwise rotation of the second rotating disk 138 as an example, in the process of the arc-shaped guiding edge 13811 sliding out from the sliding side of the arc-shaped limiting groove 1132, see Figure 15After the arc-shaped guide edge 13811 slides over the center of the arc-shaped limiting groove 1132, the transmission column 1382 first reaches the opening of the transmission slide 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 slide groove 1133 on the sliding-in side of the arc-shaped limiting groove 1132. After the transmission column 1382 slides into the transmission slide groove 1133, as the second rotating disk 138 continues to rotate, the arc-shaped guide edge 13811 gradually slides out from the sliding-out side of the arc-shaped limiting groove 1132 that it matches and eventually disengages from the arc-shaped limiting groove 1132. At the same time, the transmission column 1382 drives the rotating shaft fixing rotary disk 113 to rotate in the opposite direction to the second rotating disk 138; see Figure 16 , the transmission column 1382 first gradually slides toward the bottom of the transmission chute 1133 until it reaches the bottom of the transmission chute 1133; Figure 17 Then, the transmission column 1382 gradually slides toward the opening of the transmission slot 1133 until it is separated from the opening of the transmission slot 1133 to fix the turntable 113 with the rotating shaft.

[0105] Continue to see Figure 16 and Figure 17 In the process of the transmission column 1382 sliding out of the transmission slide 1133, the arc-shaped guide edge 13811 slides into the sliding side of the next arc-shaped limiting groove 1132. After the transmission column 1382 is separated from the opening of the transmission slide 1133 and the shaft fixing turntable 113, the cooperation of the arc-shaped guide edge 13811 and the arc-shaped limiting groove 1132 limits the shaft fixing turntable 113 until the second rotating disk 138 rotates further and returns to the position as shown in FIG. Figure 14 The status shown.

[0106] It can be understood that the distribution range of the limiting protrusion 1381 (for example, the central angle of the circle), the distance from the transmission column 1382 to the axis of the drive shaft 137, the depth of the transmission groove 1133, etc. can be configured accordingly based on the above relative position relationship.

[0107] In the above technical solution, by configuring the rotating shaft fixed turntable 113 and the second rotating disk 138 that cooperate with each other, the driving shaft 137 can also drive the second rotating disk 138 to drive the rotating shaft fixed turntable 113 to rotate during the process of outputting power to drive the moving seat 121 to rise. The upward-facing rubber strip material 230 is switched by the rotation of the rotating shaft fixed turntable 113 as the target to be measured. Compared with separately configuring power to drive the motor rotor 200 to rotate, this design method is more convenient to operate.

[0108] See also Figure 18In some further implementation schemes, the shaft fixing turntable 113 is further provided with a shaft fixing sleeve 1134 located in the shaft fixing groove 1131, and the shaft fixing sleeve 1134 is used to insert and fix the rotor shaft 210; the shaft fixing sleeve 1134 is rotatably matched with the shaft fixing groove 1131 within a preset angle; that is, the shaft fixing sleeve 1134 can drive the motor rotor 200 to rotate relative to the shaft fixing groove 1131 within a preset angle.

[0109] Optionally, the preset angle is a smaller angle, for example, less than 10°, further less than 5°. Exemplarily, in the cross-section of the rotating shaft fixing sleeve 1134 and the rotating shaft fixing groove 1131, the main body is circular; a portion of the circular body is provided with a fan-shaped ear portion protruding outward, wherein the central angle corresponding to the fan-shaped ear portion of the rotating shaft fixing sleeve 1134 is smaller than the central angle corresponding to the fan-shaped ear portion 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 the preset angle.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] As an example, the gas compression transmission element 11331 includes a connecting rod, a telescopic spring, and a slide. The slide is slidably connected to the body of the rotating shaft fixed turntable 113 along the depth direction of the transmission slot 1133. The width of the slide matches the transmission post 1382. The connecting rod extends along the depth direction of the transmission slot 1133. The bottom end of the connecting rod is connected to the gas compression piston 11351. The rod body of the connecting rod is slidably inserted into the slide. The telescopic spring is mounted on the connecting rod and abuts between the slide and the gas compression piston 11351. Based on this, when the transmission column 1382 slides into the transmission slot 1133, in the process of the transmission column 1382 sliding toward the bottom of the transmission slot 1133, the transmission column 1382 drives the slide plate to slide toward the bottom of the transmission slot 1133, the slide plate squeezes the telescopic spring, and the telescopic spring drives the gas compression piston 11351 to slide toward the bottom of the gas compression chamber 1135, and the gas in the gas compression chamber 1135 is compressed during the sliding process; in the process of the transmission column 1382 sliding from the bottom of the transmission slot 1133 toward the opening, the telescopic spring exerts a force on the slide plate, causing the slide plate to slide from the bottom of the transmission slot 1133 toward the opening and return to its initial position. At the same time, the effect of the telescopic spring on the gas compression piston 11351 is reduced, and under the action of the air pressure in the gas compression chamber 1135, the gas compression piston 11351 slides toward the direction close to the transmission slot 1133 and returns to its initial position.

[0114] A clamping piston 11311 and a clamping plate 11312 are provided in the rotating shaft fixing groove 1131. The clamping plate 11312 is connected to the side of the clamping piston 11311 close to the rotating shaft fixing sleeve 1134. The bottom of the rotating shaft fixing groove 1131 is connected to the gas compression chamber 1135, so that when the gas in the gas compression chamber 1135 is compressed, the clamping piston 11311 slides toward the side close to the rotating shaft fixing sleeve 1134 and drives the clamping plate 11312 to clamp the rotating shaft fixing sleeve 1134.

[0115] When the transmission post 1382 is engaged with the transmission chute 1133, the motor rotor 200 is rotated to switch the rubber strip material 230 to be tested. Based on this design, during the process of rotating the motor rotor 200 to switch the rubber strip material 230 to be tested, the engagement of the transmission post 1382 with the transmission chute 1133 enables the pressing plate 11312 to press against the rotating shaft fixing sleeve 1134, effectively maintaining the rotating shaft fixing sleeve 1134 and the rotating shaft fixing slot 1131 in relative fixation, thereby achieving a more accurate rotation angle of the motor rotor 200.

[0116] As an example, the clamping piston 11311 and the clamping plate 11312 are connected by a connecting shaft, and a return spring is provided on the outer sleeve of the connecting shaft. The return spring is supported between the body of the shaft fixing turntable 113 and the clamping piston 11311. When the transmission column 1382 slides out of the opening of the transmission slide groove 1133, the return spring pushes the clamping piston 11311 to move toward the bottom of the shaft fixing groove 1131 to reset.

[0117] In a second aspect, an embodiment of the present application provides an automated motor assembly system (not shown), comprising the motor rotor gluing quality detection device 100 provided in the above embodiment.
