[0002] The automotive generator is the main power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally, and at the same time charge the battery. Automotive generators can be divided into DC generators and AC generators. Since AC generators are superior to DC generators in many aspects, DC generators have been phased out.

[0003] When the existing appearance detection device for automotive generators performs appearance detection on the automotive generator, it generally needs to clean the outer wall of the generator to avoid stains on the outer shell of the automotive generator affecting the detection results. After the automotive generator is cleaned, it also needs to be air-dried. However, due to the limited air-drying effect in the position close to the inner side of the automotive generator, parts in some areas are stained with water stains, which not only causes external light refraction and affects the image acquisition of the visual detector, but also the excess water vapor floating in the air will affect the clarity when the visual detector takes pictures.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. An appearance detection device for an automotive generator provided by the present invention starts the flipping mechanism to drive the automotive generator to flip. Under the push of the limiting mechanism, the automotive generator continuously vibrates. By making the automotive generator vibrate continuously, the residual water stains inside the automotive generator are accelerated to drip. On the other hand, the connection stability of each component of the automotive generator can be detected during this process. At the same time, start the electric hot air blower to conduct hot air on the automotive generator. The filtering component is used to filter the moisture in the air flow at the air inlet of the electric hot air blower. At this time, the thrust component can push the guiding mechanism to swing. Under the guiding action of the guiding mechanism, the hot air dries the automotive generator in a large area and at multiple angles.

[0022] 2. An appearance detection device for an automotive generator provided by the present invention starts the electric lifting rod to extend, and at the same time makes the guiding mechanism close to the middle to form a cone. The guiding mechanism and the filtering component block the visual detector and the surrounding of the detection part of the automotive generator, so as to avoid interference from external light sources. At the same time, all the LED tubes at the lower position inside the guiding mechanism are turned on, and each LED tube illuminates the detection part of the automotive generator. Each LED tube can perform corresponding brightness adjustment, so as to maintain the best external lighting conditions during the detection of the visual detector.

[0023] 3. When the visual detector is interfered by water vapor reflection during detection in an appearance detection device for an automotive generator provided by the present invention, at this time, start the electric lifting rod to extend. The electric lifting rod drives the guiding mechanism to move downwards. The guiding mechanism drives all the guiding mechanisms to elastically abut against the parts of the automotive generator on the lower side. At this time, each guiding mechanism is arranged in a ring around the detection part to conduct contact heating on the parts, so that the water vapor near the detection part quickly evaporates.

[0024] 4. Start the electric hot air blower in an appearance detection device for an automotive generator provided by the present invention. Since the guiding mechanism closes to the middle to form a cone, under the guiding action of the guiding mechanism, the hot air conducts concentrated hot air on the detection part from top to bottom. The water vapor in the air in the lower area of the visual detector evaporates under the heating and high temperature of the guiding mechanism. At the same time, each guiding mechanism blows lateral air on the heating part from different directions. Under the guiding action of the guiding mechanism and each guiding mechanism, the water vapor in the air near the detection part is fully taken away, so as to effectively avoid the water vapor in the air affecting the shooting clarity of the visual detector.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0036] As Figures 1-8As shown in the figure, an appearance detection device for an automotive generator provided by the present invention includes a detection table 1. A sliding frame 2 is horizontally slidably connected to the upper end surface of the detection table 1. A fixed frame 3 is also fixedly connected to the upper end surface of the detection table 1. A driving component 10 for driving the horizontal movement of the sliding frame 2 is arranged on the fixed frame 3. A flipping mechanism 4 is arranged on the sliding frame 2. The flipping mechanism 4 can fix the automotive generator and drive the automotive generator to flip. A limiting mechanism 5 is also arranged on the sliding frame 2. When the automotive generator flips with the flipping mechanism 4, the limiting mechanism 5 can push the automotive generator to continuously vibrate.

[0037] A telescopic electric lifting rod 11 is fixedly connected to the middle of the fixed frame 3. The telescopic end of the electric lifting rod 11 is fixedly connected to a hot air blower 12. The hot air blower 12 is connected to a flow guiding mechanism 6. The flow guiding mechanism 6 can guide the air flow. A visual detector 14 is fixedly arranged in the middle of the flow guiding mechanism 6. The electric lifting rod 11 is also connected to a filtering component 7. The filtering component 7 can block the upper light and filter the moisture in the air. The filtering component 7 is also connected to a thrust component 8. The thrust component 8 can push the flow guiding mechanism 6 to swing. When the flow guiding mechanism 6 closes towards the middle, the flow guiding mechanism 6 can enclose into a cone shape. The flow guiding mechanism 6 is connected to a plurality of guiding mechanisms 9. The guiding mechanisms 9 can elastically abut against the lower automotive generator parts and heat them. At the same time, all the guiding mechanisms 9 can also blow hot air to the detection part from the side.

[0038] A plurality of LED lamps 13 are arranged at a position near the lower part of the inner side of the flow guiding mechanism 6.

[0039] Working principle:

[0040] Before detection stage:

[0041] Fix the rinsed automotive generator on the flipping mechanism 4. Then start the flipping mechanism 4 to drive the automotive generator to flip. Under the push of the limiting mechanism 5, the automotive generator continuously vibrates. By making the automotive generator continuously vibrate, the residual water stains inside the automotive generator are accelerated to drip. On the other hand, the connection stability of each component of the automotive generator can be detected during this process. At the same time, start the hot air blower 12 to heat the automotive generator with hot air. The filtering component 7 is used to filter the moisture in the air flow at the air inlet of the hot air blower 12. At this time, the thrust component 8 can push the flow guiding mechanism 6 to swing. Under the guiding action of the flow guiding mechanism 6, the hot air dries the automotive generator in a large area and at multiple angles.

[0042] Detection stage:

[0043] The electric lifting rod 11 is started to extend, and at the same time, the diversion mechanism 6 is closed towards the middle to form a cone shape. At this time, the limit mechanism 5 is stopped from pushing the automobile generator to vibrate, and the flipping mechanism 4 drives the automobile generator to flip. At the same time, the driving assembly 10 can drive the automobile generator to move horizontally, so that each part of the automobile generator passes under the visual detector 14 in turn. During this process, the diversion mechanism 6 and the filtering assembly 7 block the visual detector 14 and the surrounding of the detection part of the automobile generator, so as to avoid the interference of external light sources. At the same time, all the LED tubes 13 at the lower position on the inner side of the diversion mechanism 6 are turned on, and the detection part of the automobile generator is illuminated by each LED tube 13. Each LED tube 13 can perform corresponding brightness adjustment, so as to maintain the best external light conditions during the detection of the visual detector 14;

[0044] Since the drying effect of the position of the automobile generator close to the inner side is limited, water stains adhere to the parts in some areas, which not only causes the refraction of external light and affects the image acquisition of the visual detector 14, but also the excess water vapor floating in the air will affect the clarity of the visual detector 14 during shooting;

[0045] In this embodiment, when the visual detector 14 is interfered by water vapor reflection during detection, the electric lifting rod 11 is started to extend at this time. The electric lifting rod 11 drives the diversion mechanism 6 to move downward. The diversion mechanism 6 drives all the guiding mechanisms 9 to elastically abut against the parts of the automobile generator below. At this time, each guiding mechanism 9 is arranged in a ring around the detection part to perform contact heating on the parts, so that the water vapor near the detection part evaporates quickly; At the same time, the electric hot air blower 12 is started. Since the diversion mechanism 6 is closed towards the middle to form a cone shape at this time, under the guiding action of the diversion mechanism 6, the hot air focuses on the detection part from top to bottom. The water vapor in the air in the area below the visual detector 14 evaporates under the heating and high temperature of the diversion mechanism 6. At the same time, each guiding mechanism 9 blows air laterally on the heating part from different directions. Under the guiding action of the diversion mechanism 6 and each guiding mechanism 9, the water vapor in the air near the detection part is fully taken away, so as to effectively avoid the water vapor in the air from affecting the shooting clarity of the visual detector 14.

[0046] As Figure 2 shown, as a preferred embodiment of the present invention, the flipping mechanism 4 includes a rotating frame 41, an elastic telescopic rod 42, a first motor 43, a limiting rod 44 and an electric push plate 45;

[0047] The rotating frame 41 is arranged in the middle of the sliding frame 2. Elastic telescopic rods 42 and limiting rods 44 are respectively fixedly connected to both ends of the rotating frame 41. The sliding frame 2 is fixedly connected with a first motor 43. The output shaft of the first motor 43 is fixedly connected to one end of the elastic telescopic rod 42. Electric push plates 45 are fixedly connected to the side walls at both ends of the rotating frame 41.

[0048] In an embodiment of the present invention, the automotive generator is placed on the rotating frame 41, and then the electric push plates 45 on both sides are started to fix the automotive generator. The first motor 43 is started, and the first motor 43 drives the rotating frame 41 to rotate through the elastic telescopic rod 42, and the rotating frame 41 drives the automotive generator to flip.

[0049] As Figure 3 shown, as a preferred embodiment of the present invention, the limiting mechanism 5 includes a first electric telescopic sleeve 51, a toothed disc 52, a turntable 53, an electric telescopic seat 54 and a positioning rod 55;

[0050] The fixed end of the first electric telescopic sleeve 51 is rotatably connected to the sliding frame 2. The limiting rod 44 is inserted into the first electric telescopic sleeve 51. The telescopic end of the first electric telescopic sleeve 51 is provided with a plurality of meshing grooves. A toothed disc 52 is fixedly connected to the outer side wall of the flipping mechanism 4. The telescopic end of the first electric telescopic sleeve 51 meshes with the toothed disc 52. The fixed end of the first electric telescopic sleeve 51 is fixedly connected to a turntable 53. The turntable 53 is annularly provided with a plurality of jacks. The sliding frame 2 is fixedly connected with an electric telescopic seat 54, and the electric telescopic seat 54 is fixedly connected with a positioning rod 55, and the positioning rod 55 is aligned with one of the jacks.

[0051] In an embodiment of the present invention, after the automotive generator is fixed on the rotating frame 41, if it is necessary to drive the automotive generator to flip stably, at this time, the first electric telescopic sleeve 51 is started to extend. The first electric telescopic sleeve 51 pushes the rotating frame 41 to squeeze the elastic telescopic rod 42, so that the elastic telescopic rod 42 is squeezed to the limit. At this time, the first electric telescopic sleeve 51, the toothed disc 52, the limiting rod 44, the elastic telescopic rod 42 and the rotating frame 41 are fixedly locked in the horizontal direction. The first motor 43 drives the rotating frame 41 to rotate through the elastic telescopic rod 42. At this time, under the extrusion force of the first electric telescopic sleeve 51 and the toothed disc 52, the first electric telescopic sleeve 51 and the limiting rod 44 rotate synchronously with the rotating frame 41;

[0052] Before detection: Start the positioning rod 55 to extend, and the positioning rod 55 is inserted into the jack on the turntable 53. At this time, the first electric telescopic sleeve 51 contracts to a certain extent. Under the elastic force of the elastic telescopic rod 42, the rotating frame 41 drives the toothed disc 52 to elastically squeeze the first electric telescopic sleeve 51. When the first motor 43 drives the rotating frame 41 to rotate through the elastic telescopic rod 42, at this time, under the guiding action of the first electric telescopic sleeve 51 and the elastic force of the elastic telescopic rod 42, the toothed disc 52 drives the rotating frame 41 to vibrate horizontally back and forth, and the rotating frame 41 drives the automotive generator to vibrate back and forth, so as to quickly drip or disperse the water stains on the automotive generator.

[0053] As Figure 6 and Figure 7As shown, as a preferred embodiment of the present invention, the diversion mechanism 6 includes a disc 61, a rotating rod 62, a diversion plate 63 and a rubber strip 64;

[0054] The telescopic end of the electric lifting rod 11 is fixedly connected to a disc 61. The visual detector 14 is fixedly connected to the middle position of the lower end surface of the disc 61. The disc 61 is rotatably connected with a plurality of rotating rods 62 along the circumferential direction. The central cylinder 65 of the rotating rod 62 is inserted into the rotating seat on the disc 61, and an elastic torsion spring is connected between the rotating rod 62 and the rotating seat on the disc 61. One end of the rotating rod 62 is fixedly connected to a diversion plate 63. The diversion plate 63 is fan-shaped. An air outlet is provided at the bottom of the diversion plate 63. Rubber strips 64 are provided on both side walls of the diversion plate 63;

[0055] The air outlet of the electric hot air blower 12 is communicated with the disc 61. The central cylinder 65 of the rotating rod 62 is communicated with the disc 61 through the rotating seat on the disc 61.

[0056] In the embodiment of the present invention, when the electric hot air blower 12 is started, the electric hot air blower 12 heats the external wind. After the external wind enters the disc 61 from the electric hot air blower 12, the hot air diffuses from each disc 61 into each diversion plate 63, and the wind is guided by each diversion plate 63.

[0057] As Figure 5 shown, as a preferred embodiment of the present invention, the filtering assembly 7 includes a baffle 71, a diversion sleeve 72 and a filter net 73;

[0058] The baffle 71 is fixedly connected to the telescopic end of the electric lifting rod 11. A plurality of strip-shaped holes are formed in the baffle 71 along the annular direction. A diversion sleeve 72 is provided on the upper side of each strip-shaped hole. All the diversion sleeves 72 are communicated with the strip-shaped holes on the baffle 71. The upper end surface of the diversion sleeve 72 is inclined. A filter net 73 is provided on the side end surface of the diversion sleeve 72.

[0059] In the embodiment of the present invention, the upper part of the visual detector 14 is blocked by the baffle 71, so as to avoid the influence of the external light condition on the shooting of the visual detector 14. A plurality of diversion sleeves 72 are provided on the baffle 71. Through the side openings of the diversion sleeves 72, while the baffle 71 blocks the outside light, it is ensured that the external air can flow to the lower side of the baffle 71. At the same time, the moisture impurities in the external air entering are filtered by the filter net 73, so that dry air flow can be stably introduced at the air inlet of the electric hot air blower 12.

[0060] As Figure 5 shown, as a preferred embodiment of the present invention, the thrust assembly 8 includes a second electric telescopic sleeve 81, an airbag 82 and an air pump 83;

[0061] A second electric telescopic sleeve 81 is provided on the lower end surface of the baffle 71. The telescopic end of the second electric telescopic sleeve 81 is fixedly connected to an annular push plate 84. An airbag 82 is provided on the inner wall of the telescopic end of the second electric telescopic sleeve 81. The telescopic end of the second electric telescopic sleeve 81 is fixedly connected to an air pump 83. The air outlet of the air pump 83 is communicated with the airbag 82.

[0062] In the embodiment of the present invention, when the second electric telescopic sleeve 81 is started to contract, the annular push plate 84 on the second electric telescopic sleeve 81 simultaneously pushes all the rotating rods 62 to rotate. All the rotating rods 62 drive the connected flow guide plates 63 to rotate outwards. When the second electric telescopic sleeve 81 extends, at this time, under the action of each elastic torsion spring, all the flow guide plates 63 are reversely flipped and reset. Therefore, when the second electric telescopic sleeve 81 reciprocates telescopically, all the flow guide plates 63 can reciprocate to rotate, so as to blow and dry the lower automotive generator in a large area and at multiple angles;

[0063] When the second electric telescopic sleeve 81 extends, all the flow guide plates 63 close together to form a cone in the middle. At this time, the air pump 83 is started to inflate the airbag 82, and the airbag 82 blocks the gap between the disc 61 and each flow guide plate 63. The middle of each flow guide plate 63 is sealed by a rubber strip 64. Through the cooperation of the airbag 82 and all the rubber strips 64, the external light can be blocked to the greatest extent between the visual detector 14 and the detection part of the automotive generator. At the same time, all the LED tubes 13 are started to adjust the light brightness of the detection part of the automotive generator, so as to improve the detection accuracy of the visual detector 14;

[0064] When all the flow guide plates 63 concentrate on guiding air to the detection part, under the reverse thrust of the wind force, the disc 61 and all the flow guide plates 63 will inevitably vibrate, which will affect the stability of the visual detector 14 during shooting. In this embodiment, the airbag 82 elastically limits all the flow guide plates 63 to the middle. At the same time, each flow guide plate 63 elastically abuts against each other through each rubber strip 64, which can ensure the stability of the visual detector 14 during shooting to the greatest extent.

[0065] As Figure 8 As shown, as a preferred embodiment of the present invention, the guiding mechanism 9 includes an elastic telescopic sleeve 91 and air guiding holes 92. The fixed end of the elastic telescopic sleeve 91 is fixedly connected to the outer side wall of the flow guide plate 63. The elastic telescopic sleeve 91 is internally communicated with the flow guide plate 63. An electric heater is arranged in the elastic telescopic sleeve 91. A plurality of air guiding holes 92 are opened at the telescopic end of the elastic telescopic sleeve 91. The end of the telescopic end of the elastic telescopic sleeve 91 is provided with an inclined surface. A flow control valve is arranged at the position of the flow guide plate 63 close to the bottom air outlet.

[0066] In the embodiment of the present invention, each elastic telescopic sleeve 91 is elastically abutted against the parts around the detection part of the automotive generator. At this time, the diversion mechanism 6 forms a connection contact with the automotive generator through each elastic telescopic sleeve 91, further improving the stability of the diversion mechanism 6 when blowing air. An electric heater is provided in the elastic telescopic sleeve 91, and the parts around the automotive generator can be heated when contacting through the elastic telescopic sleeve 91, thereby increasing the water vapor evaporation rate of the detection part of the automotive generator; each elastic telescopic sleeve 91 can also hot air dry the automotive generator from different angles.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
