Description

Technical Field

[0001] The present invention relates to the technical field of stator testing, and in particular to a stator comprehensive testing device and a method thereof. Background Art

[0002] The stator comprehensive tester measures the resistance value of the stator through the resistance test function. This helps to determine whether the conductor of the stator is normal and whether the connection is good. Resistance test is the basis of stator quality detection, which can reflect the conductor material and connection of the stator winding. The tester also has the function of winding turn-to-turn resistance test. The winding turn-to-turn resistance is an important indicator of the motor stator, which reflects the winding condition and insulation quality of the stator. By measuring the winding turn-to-turn resistance value, it can be determined whether the winding quality of the stator is normal and whether the insulation is good.

[0003] The stator is a key part of the motor that generates a rotating magnetic field. Its shape has an important influence on the distribution of the magnetic field. The stator is generally designed to be cylindrical, which makes the stator more uniform in magnetic field distribution, thereby improving the running stability of the motor and reducing noise.

[0004] In order to ensure the test efficiency, the stator is usually laid flat or stood upright for wiring detection during the test. However, since the number of stators in each batch is not fixed, the staff needs to frequently load and unload the materials. Since wiring work is required after each loading and unloading, the loading work of other workstations can no longer be taken care of. This also increases the equipment testing idle period, thereby greatly reducing the test efficiency and the entire test takes a long time. Summary of the invention

[0022] A method for testing using a stator comprehensive testing device as described above, wherein: the method comprises the following steps:

[0023] Step 1: Place the required test stators one by one and roll them into the loading chamber, and place no less than two stator counterweight models that do not need to be tested at the end, and the arc-shaped long plate is first aligned with the discharge port of the loading chamber; It should be explained that the stator counterweight model is a model body with the same size and mass as the actual stator, and is mainly used to subsequently determine whether the stator in the entire chamber has been completely loaded.

[0024] Step 2: By starting the drive motor, under the cooperation of the first bevel gear, the transmission bevel gear and the second bevel gear, the longitudinal transmission shaft and the transverse transmission shaft both start to rotate, so that the first reciprocating screw and the second reciprocating screw start to work;

[0025] When the V-shaped material carrier on one side of the first material guide platform reaches the loading position, the second electromagnetic clutch is powered off. At this time, the V-shaped material carrier on the other side is at the detection position, and the stator that first passes through the arc-shaped long plate begins to climb until it rolls down and touches the guide bar under the action of gravity. At this time, it passes through the first material guide platform and falls onto the V-shaped material carrier. The second electromagnetic clutch is powered on again, and the lead screw slider moves back along the first reciprocating lead screw, that is, the V-shaped material carrier on one side of the first material guide platform is transferred from the loading position to the detection position. On the contrary, the V-shaped material carrier on the second material guide platform begins to transfer from the detection position to the upper material position.

[0026] Step 3: When the V-shaped material carrier on one side of the second material guide table reaches the loading position, the second electromagnetic clutch is powered off, and the material blocking mechanism controls the material discharge to allow the stator driven by the arc short plate to climb. Since the arc length of the arc short plate is not enough, when the arc short plate drives the stator to the top of the loading cavity, it rolls onto the V-shaped material carrier under the action of gravity, and the second electromagnetic clutch is powered on again until the V-shaped material carrier on the second material guide table side returns to the detection position, and the above process is repeated to complete the alternating detection of the workstations on both sides;

[0027] Step 4: When the arc-shaped long plate or the arc-shaped short plate appears to convey the pre-arranged stator counterweight model, it means that all stators in the loading bin room have been tested.

[0028] Beneficial effects of the present invention:

[0029] 1.

When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0046] Embodiment 1, refer to Figure 1-Figure 9 , as an embodiment of the present invention, provides a stator comprehensive testing device, the device comprising:

[0047] The test main unit 100 includes: a front loading platform 101, a rear detection platform 102 located at the rear side of the front loading platform 101, a V-shaped load-bearing frame 110 slidably arranged on both sides above the front loading platform 101, and a mounting frame 103 fixedly arranged on the rear detection platform 102, on which a detection display screen 106 for displaying test data is installed, and a loading chamber 107 is also arranged on one side of the front loading platform 101, and a material blocking mechanism is arranged on the discharge port side of the loading chamber 107, which includes: a blocking cylinder 107a fixed on the inner side of the front loading platform 101 and a gate 107b fixed on the output end of the blocking cylinder 107a; here, the blocking cylinder 107a is turned on and off to control the stator to discharge materials in an orderly manner at intervals, that is, only when the previous detection stator completely falls into the V-shaped load-bearing frame 110, the next stator can discharge materials.

[0048] Specifically, the front loading platform 101 is symmetrically fixedly connected with the front rail 108, the rear inspection platform 102 is symmetrically fixedly connected with the rear rail 109, the bottom of the V-shaped material carrier 110 is fixedly connected with the rail slider 110b that slides with the front rail 108 and the rear rail 109, and the side of the V-shaped material carrier 110 is also fixedly provided with a buffer side wing plate 110a. The stator rolling down during the loading is buffered, and a gap is left between the front rail 108 and the rear rail 109 for detecting the passage of the protective cover 105 after it is lowered, so that the protective cover 105 can completely cover the stator in the V-shaped material carrier 110 during the test.

[0049] The stator loading unit 200 includes: a loading chamber shell 201 arranged on the inner side of the front loading platform 101, material rollers 202 rotatably connected to the upper and lower sides of the loading chamber shell 201, and a conveying chain plate 204 arranged on the upper and lower side material rollers 202, and a plurality of arc-shaped long plates 205 and arc-shaped short plates 206 arranged on the conveying chain plate 204; in order to accurately identify whether the stator being discharged falls on the arc-shaped long plate 205 or the arc-shaped short plate 206, a barcode or QR code can be scanned, and a barcode or QR code can be affixed to the arc-shaped conveying long plate and short plate. When the conveying plate arrives at the designated location, the barcode or QR code information is read by a scanner to confirm the position, and the signal obtained by the integrated scanner is used to perform logical judgment and control the discharge through a PLC or a control system. This belongs to the conventional determination technical means in the field of transportation and will not be elaborated here.

[0050] In addition, a loading cavity 203 for stator loading and climbing is provided between the loading chamber shell 201 and the conveying chain plate 204, and a feeding port aligned with the discharge port of the loading chamber 107 is provided on one side of the loading chamber shell 201, and a first material guide platform 111 and a second material guide platform 112 are symmetrically provided on both sides of the discharge port of the loading chamber shell 201, and the first material guide platform 111 and the second material guide platform 112 are both inclined. The loading stations corresponding to the two sides respectively enable the stator to be loaded in an orderly manner from different sides.

[0051] It should be noted that the arc length of the cross section of the long arc plate 205 is greater than one quarter of the arc length of the cross section of the stator under test, and the cross section length of the short arc plate 206 is less than one quarter of the arc length of the cross section of the stator under test. That is to say, when the long arc plate 205 drives the stator to rise, the stator can pass the conveying high position, so as to complete the blanking from one side of the first material guide platform 111, and after the short arc plate 206 drives the stator to rise and takes the stator out of the loading cavity 203, it cannot independently convey the stator to pass the conveying high position due to insufficient arc length, and under the action of gravity, the blanking is completed directly from one side of the second material guide platform 112, the long arc plate 205 and the short arc plate 206 are alternately and evenly spaced, and the spacing distance between them only allows a single stator to enter, and the long arc plate 205 and the short arc plate 206 are both provided with notch grooves 207, and the first material guide platform 111 is fixedly connected to the side of the loading cavity 203 with a guide bar 111a matching the size of the notch groove 207. The guide bar 111 a is mainly used to guide the stator and does not affect the normal movement of the arc-shaped long plate 205 and the arc-shaped short plate 206 .

[0052] The driving main unit 300 includes: a driving motor 301 fixedly installed on the rear side of the rear detection platform 102 and used to drive the material roller 202 to rotate, and a vertical transmission shaft rotatably connected to the inner side of the rear detection platform 102 through a connecting sleeve 306, and the upper and lower ends of the vertical transmission shaft are fixedly connected with a transmission bevel gear 303, and the output shaft of the driving motor 301 is fixedly connected with a first bevel gear 302 meshing with the transmission bevel gear 303 at the lower end, and a transverse transmission shaft is also rotatably connected between the inner side of the rear detection platform 102 and the material loading chamber shell 201, and the transverse transmission shaft is fixedly connected with a second bevel gear 307 meshing with the transmission bevel gear 303 at the upper end;

[0053] Among them, the first reciprocating screw 312 and the second reciprocating screw 313 are rotatably connected between the rear detection platform 102 and the front loading platform 101, and screw sliders 314 are provided on the first reciprocating screw 312 and the second reciprocating screw 313, and the screw sliders 314 are fixedly connected to the bottom of the V-shaped load-bearing frame 110 through a connecting frame 315. The transverse transmission shaft and the first reciprocating screw 312 and the second reciprocating screw 313 are connected through a belt transmission assembly. The belt transmission assembly includes a driving wheel 308 rotatably connected to the transverse transmission shaft, a rotating shaft 318 rotatably connected to the back side of the rear detection platform 102, and a driven wheel 310 rotatably connected to the first reciprocating screw 312 and the rotating shaft 318, respectively, and a transmission belt 311 is provided between the driven wheel 310 and the driving wheel 308.

[0054] The first circular gear 316 is fixedly inserted and connected to the rotating shaft 318, and the second circular gear 317 is fixedly inserted and connected to the end of the second reciprocating screw 313, and the second circular gear 317 is meshed and connected with the first circular gear 316. Tension rollers 309 are symmetrically arranged on both sides of the driving wheel 308, and the tension rollers 309 are rotatably connected to the back side of the rear detection platform 102. That is to say, by driving the motor 301, the first reciprocating screw 312 and the second reciprocating screw 313 can be driven by the belt transmission assembly to realize the opposite rotation of the first reciprocating screw 312 and the second reciprocating screw 313, thereby controlling the movement directions of the V-shaped material carriers 110 on both sides to be opposite.

[0055] Example 2, refer to Figure 1-9 , which is different from the first embodiment, a first electromagnetic clutch 304 is provided on the side of the output end of the driving motor 301 close to the material loading chamber housing 201, and a second electromagnetic clutch 305 is provided on the vertical transmission shaft. The first electromagnetic clutch 304 and the second electromagnetic clutch 305 are controlled to be powered on and off, so as to temporarily stop or start the rotation of the material roller 202, the first reciprocating screw 312 and the second reciprocating screw 313. The mounting frame 103 is symmetrically fixedly connected with a telescopic cylinder 104, and the output end of the telescopic cylinder 104 is symmetrically fixedly connected with a detection protective cover 105. Protective shielding work is performed under the test detection protective cover 105.

[0056] The remaining structures are the same as those in the first embodiment, and the test method applied to the above-mentioned stator comprehensive test equipment comprises the following steps:

[0057] Step 1: Place the required test stators in turn and roll them into the loading chamber 107, and place no less than two stator counterweight models that do not need to be tested at the end, and the arc-shaped long plate 205 is first aligned with the discharge port of the loading chamber 107; It should be explained that the stator counterweight model is a model body that is consistent with the actual stator body size and mass, and is mainly used for subsequent judgment of whether the stator in the entire chamber has been completely loaded.

[0058] Step 2: By starting the driving motor 301, under the cooperation of the first bevel gear 302, the transmission bevel gear 303 and the second bevel gear 307, the longitudinal transmission shaft and the transverse transmission shaft start to rotate, so that the first reciprocating screw 312 and the second reciprocating screw 313 start to work;

[0059] When the V-shaped material carrier 110 on one side of the first material guide platform 111 reaches the loading position, the second electromagnetic clutch 305 is powered off. At this time, the V-shaped material carrier 110 on the other side is at the detection position, and the stator that first passes through the arc-shaped long plate 205 begins to climb until it rolls down and touches the guide bar 111a under the action of gravity, and then passes through the first material guide platform 111 and falls onto the V-shaped material carrier 110. The second electromagnetic clutch 305 is powered on again, and the lead screw slider 314 moves back along the first reciprocating lead screw 312, that is, the V-shaped material carrier 110 on one side of the first material guide platform 111 is transferred from the loading position to the detection position, and on the contrary, the V-shaped material carrier 110 on the second material guide platform 112 begins to transfer from the detection position to the upper material position;

[0060] Step 3: When the V-shaped material carrier 110 on one side of the second material guide platform 112 reaches the loading position, the second electromagnetic clutch 305 is powered off, and the material blocking mechanism controls the discharge to allow the stator driven by the arc-shaped short plate 206 to climb. Since the arc length of the arc-shaped short plate 206 is not enough, when the arc-shaped short plate 206 drives the stator to the top of the loading cavity 203, it rolls onto the V-shaped material carrier 110 under the action of gravity, and the second electromagnetic clutch 305 is powered on again until the V-shaped material carrier 110 on the second material guide platform 112 side returns to the detection position, and the above process is repeated to complete the alternating detection of the workstations on both sides;

[0061] Step 4: When the arc-shaped long plate 205 or the arc-shaped short plate 206 conveys the pre-arranged stator counterweight model, it means that the testing of all stators in the loading chamber 107 is completed.

[0062] In summary, the present invention arranges V-shaped loading racks 110 on both sides of the equipment, so that when the V-shaped loading rack 110 on one side is loading and unloading, the V-shaped loading rack 110 on the other side can perform wiring testing work normally, which greatly reduces the idle period of equipment detection and improves the detection efficiency. By setting arc conveying plates of different lengths, different discharge positions can be achieved at one feeding position according to different detection positions, thereby meeting the alternating loading requirements of the V-shaped loading racks 110 on both sides, greatly reducing the loading burden of the staff and improving work efficiency.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

10. A testing method applied to the stator comprehensive testing equipment according to claim 9, characterized in that: The method comprises the following steps: Step 1: Place the required stators for testing in turn and roll them into the loading chamber (107), and place at least two stator weight models that do not need to be tested at the end, and the arc-shaped long plate (205) is first aligned with the discharge port of the loading chamber (107); Step 2: By starting the driving motor (301), under the cooperation of the first bevel gear (302), the transmission bevel gear (303) and the second bevel gear (307), the longitudinal transmission shaft and the transverse transmission shaft both start to rotate, so that the first reciprocating screw (312) and the second reciprocating screw (313) start to work; When the V-shaped material carrier (110) located on one side of the first material guide platform (111) reaches the loading position, the second electromagnetic clutch (305) is powered off. At this time, the V-shaped material carrier (110) on the other side is located at the detection position, and the stator that first passes through the arc-shaped long plate (205) begins to climb until it rolls down and contacts the guide bar (111a) under the action of gravity. At this time, it passes through the first material guide platform (111) and falls onto the V-shaped material carrier (110). The second electromagnetic clutch (305) is powered on again, and the lead screw slider (314) moves back along the first reciprocating lead screw (312), that is, the V-shaped material carrier (110) located on one side of the first material guide platform (111) moves from the loading position to the detection position, and conversely, the V-shaped material carrier (110) located on the second material guide platform (112) starts to move from the detection position to the upper material position; Step 3: When the V-shaped material carrier (110) on one side of the second material guide platform (112) reaches the loading position, the second electromagnetic clutch (305) is powered off, and the material blocking mechanism controls the material discharge to allow the stator driven by the arc-shaped short plate (206) to climb. Since the arc length of the arc-shaped short plate (206) is insufficient, when the arc-shaped short plate (206) drives the stator to the top of the loading cavity (203), it rolls onto the V-shaped material carrier (110) under the action of gravity, and the second electromagnetic clutch (305) is powered on again until the V-shaped material carrier (110) on the second material guide platform (112) returns to the detection position, and the above process is repeated to complete the alternating detection of the workstations on both sides; Step 4: When the arc-shaped long plate (205) or the arc-shaped short plate (206) conveys the pre-arranged stator counterweight model, it means that the testing of all stators in the loading chamber (107) is completed.
