Description

Technical Field

[0001] The invention relates to the field of mechanical automation, and in particular to a conveying device for quickly detecting large cylindrical batteries. Background Art

[0002] At present, most of the appearance inspections for large cylindrical batteries, such as font inspection and barcode inspection, are carried out manually.

[0036] With reference to the accompanying drawings, the above and other features of the present invention will become apparent through the following description. In the specification and the accompanying drawings, specific embodiments of the present invention are specifically disclosed, which show some embodiments in which the principles of the present invention can be adopted, and it should be understood that the present invention is not limited to the described embodiments.

[0037] The present invention provides a conveying device for quickly testing large cylindrical batteries. Figure 1 It is a structural schematic diagram of a conveying device for rapid detection of large cylindrical batteries according to the present invention. Figure 2 yes Figure 1 Schematic diagram of the transplanting movement trajectory of medium and large cylindrical batteries. Figure 3 This is an exploded view of the conveying device for rapid detection of large cylindrical batteries of the present invention. As shown in the figure, the conveying device for rapid detection of large cylindrical batteries includes a rotating mechanism 1 and a transplanting mechanism 2, and the transplanting mechanism 2 is located below the rotating mechanism 1; wherein, the rotating mechanism 1 includes a servo motor 11, and each large cylindrical battery to be detected is placed on the rotating mechanism 1. One of the large cylindrical batteries is marked as 001 in the figure as an example. The servo motor 11 drives the rotating mechanism 1 to rotate and drives each large cylindrical battery to be detected to rotate continuously. The complete appearance image of the continuously rotating large cylindrical battery is obtained through the detection camera for detection; the transplanting mechanism 2 includes a servo motor 21. While the servo motor 11 drives the rotating mechanism 1 to rotate continuously, the servo motor 21 drives the transplanting mechanism 2 to move continuously so as to transfer each large cylindrical battery to be detected located on the rotating mechanism 1 to the next position. Thus, the rotating mechanism 1 and the transplanting mechanism 2 cooperate with each other to realize the interactive detection and transplanting of each large cylindrical battery. After the large cylindrical battery completes the acquisition of the surface image while continuously rotating on the rotating mechanism 1, it is pushed by the transplanting mechanism 2, such as Figure 2As shown in the motion trajectory, the large cylindrical battery moves in an elliptical jump-like manner between adjacent rotating wheels, and is sequentially transferred to the next position on the rotating mechanism 1, avoiding the frequent start and stop of the servo motor 11 and the servo motor 21, and can fully obtain the appearance image of the large cylindrical battery to ensure the inspection quality and the inspection efficiency. According to the embodiment of the present invention, the transplanting time can be less than 0.5S, the inspection time is also 0.5S, 60 large cylindrical batteries can be inspected per minute, and the rapid inspection of large cylindrical batteries is realized. The posture of the product remains the same during discharging and feeding, thereby ensuring that there is no impact on other equipment on the production line, facilitating subsequent automated operations.

[0038] Figure 4 It is a structural schematic diagram of the rotating mechanism of the conveying device for rapid detection of large cylindrical batteries of the present invention, Figure 5 FIG. 1 is a top view of the rotating mechanism of the conveying device for rapid detection of large cylindrical batteries of the present invention, see FIG. Figure 4-Figure 5 According to a preferred embodiment of the present invention, the rotating mechanism 1 also includes a first row of rotating wheels 12 and a second row of rotating wheels 13, each row of rotating wheels includes a plurality of rotating wheels, and the figure shows rotating wheels 121, 122, 131 and 132 as examples, and the servo motor 11 drives the rotating wheels of the first row 12 and the second row 13 to rotate synchronously; there is a first spacing between two adjacent rotating wheels of the first row 12, and a second spacing between two adjacent rotating wheels of the second row 13, and the first spacing is equal to the second spacing; one end of a large cylindrical battery to be detected is carried between two adjacent rotating wheels of the first row 12, and the other end of a large cylindrical battery to be detected is carried between two adjacent rotating wheels of the second row 13. For example, refer to Figure 4 One end of the large cylindrical battery 001 is located between the rotating wheel 121 and the rotating wheel 122, and the other end of the large cylindrical battery 001 is located between the rotating wheel 131 and the rotating wheel 132. When the servo motor 11 drives the rotating wheels 121, 122, 131 and 132 to rotate synchronously, the large cylindrical battery 001 is driven to rotate continuously. Thus, the detection camera can obtain a complete appearance image of the large cylindrical battery 001 for detection. For further information, see Figure 5 There is a third spacing between the first row of rotating wheels 12 and the second row of rotating wheels 13, and the third spacing is used for the transplanting mechanism 2 disposed below to contact and transfer each large cylindrical battery to be detected. Preferably, each rotating wheel of the first row of rotating wheels 12 and the second row of rotating wheels 13 is a rubber rotating wheel, and the transplanting mechanism 2 drives each large cylindrical battery to complete an elliptical jumping movement between the rubber rotating wheels for transplantation, so as to avoid damage to the large cylindrical battery.

[0039] According to a preferred implementation of the embodiment of the present invention, see Figure 4 and Figure 5 , the ends of the rotating wheels of the first row of rotating wheels 12 away from the second row of rotating wheels 13 are fixedly connected to the first rotating synchronous belt pulleys, and one of the rotating synchronous belt pulleys 123 is marked in the figure as an example; the ends of the rotating wheels of the second row of rotating wheels 13 away from the first row of rotating wheels 12 are fixedly connected to the second rotating synchronous belt pulleys, and one of the rotating synchronous belt pulleys 133 is marked in the figure as an example; the tooth profiles of the rotating synchronous belt pulleys are the same. The output shaft of the servo motor 11 is connected to the synchronous belt pulley 125 through the synchronous belt 124, and the synchronous belt pulley 125 is connected to the synchronous belt pulley 127 through the double-sided tooth synchronous belt 126, and the upper surface of the double-sided tooth synchronous belt 126 between the synchronous belt pulley 125 and the synchronous belt pulley 127 is respectively engaged with each first rotating synchronous belt pulley. Therefore, when the output shaft of the servo motor 11 rotates, the double-sided tooth synchronous belt 126 between the synchronous belt pulley 125 and the synchronous belt pulley 127 is driven to move back and forth in a cycle, and the moving double-sided tooth synchronous belt 126 drives each rotating synchronous belt pulley to rotate, thereby driving the rotating wheels fixedly connected to each rotating synchronous belt pulley to rotate, for example Figure 5 The servo motor 11 drives the rotating wheel 122 fixedly connected to the rotating synchronous pulley 123 to rotate. Correspondingly, the output shaft of the servo motor 11 is also connected to the synchronous pulley 135 through the synchronous belt 134, and the synchronous pulley 135 is connected to the synchronous pulley 137 through the double-sided toothed synchronous belt 136. The upper surface of the double-sided toothed synchronous belt 136 between the synchronous pulley 135 and the synchronous pulley 137 is respectively engaged with each second rotating synchronous pulley. Therefore, when the servo motor 11 is activated, each rotating wheel of the first row of rotating wheels 12 and the second row of rotating wheels 13 is synchronously driven to rotate, thereby driving each large cylindrical battery to rotate continuously and stably.

[0040] Figure 6 FIG. 1 is a schematic diagram of the transfer mechanism of the conveying device for rapid detection of large cylindrical batteries of the present invention, with the second cam portion hidden. Figure 6According to a preferred embodiment of the present invention, the transplanting mechanism 2 also includes an eccentric cam 22, and the output shaft 211 of the servo motor 21 is fixedly connected to the eccentric cam 22; linear bearings 221 and linear bearings 222 are vertically arranged on both sides of the eccentric cam 22, and the linear bearing 221 is penetrated by a slide bar 223, and the linear bearing 222 is penetrated by a slide bar 224, and the upper ends of the slide bar 223 and the slide bar 224 are respectively fixedly connected to the mounting plate 23, and the mounting plate 23 is connected to the V-groove driving block 24, and the V-groove driving block 24 is located in the space of the third spacing between the first row of rotating wheels 12 and the second row of rotating wheels 13 so as to contact and transfer each large cylindrical battery of the detection object; the lower ends of the slide bar 223 and the slide bar 224 are respectively fixedly connected to the mounting plate 25, and the mounting plate 25 is slidably connected to the bottom plate 26. Thus, the servo motor 21 drives the eccentric cam 22 to rotate. Due to the eccentric design of the eccentric cam 22, it is decomposed into uniform motion in two directions, vertical up and down and horizontal left and right. The vertical up and down uniform motion is offset by the up and down movement of the linear bearing 221 relative to the slide bar 223 and the up and down movement of the linear bearing 222 relative to the slide bar 224, and finally drives the V-groove drive block 24 to move horizontally reciprocatingly relative to the base plate 26, thereby providing power for the horizontal left and right movement of each large cylindrical battery.

[0041] For further information, see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the transfer mechanism of the conveying device for rapid detection of large cylindrical batteries of the present invention, with the first cam portion hidden. Figure 8It is an installation schematic diagram of the first cam and the second cam. As shown in the figure, the transplanting mechanism 2 also includes an eccentric cam 27. The output shaft 211 of the servo motor 21 passes through the eccentric cam 22 and is fixedly connected to the eccentric cam 27; a guide rail 271 is horizontally arranged on the upper end of the eccentric cam 27, and the guide rail 271 is slidably connected to the mounting plate 28. A slide bar 281 is vertically arranged at one end of the mounting plate 28, and a slide bar 282 is vertically arranged at the other end of the mounting plate 28; linear bearings 231 and linear bearings 232 are respectively arranged at both ends of the mounting plate 23, the slide bar 281 passes through the linear bearing 231 and is fixedly connected to one end of the V-groove driving block 24, and the slide bar 282 passes through the linear bearing 232 and is fixedly connected to the other end of the V-groove driving block 24. Thus, the servo motor 21 drives the eccentric cam 27 to rotate. Due to the eccentric design of the eccentric cam 27, it is decomposed into uniform motion in the vertical up and down and horizontal left and right directions. The uniform motion in the vertical and horizontal directions is offset by the horizontal sliding of the guide rail 271 relative to the mounting plate 28, and finally drives the V-groove drive block 24 to move up and down relative to the mounting plate 23 in a circular manner, thereby providing power for the vertical up and down movement of each large cylindrical battery. Since the two eccentric wheels of the eccentric cam 22 and the eccentric cam 27 are fixedly connected to the same output shaft 211 of the servo motor 21, and the eccentric direction is the same, the output shaft 211 of the servo motor 21 synchronously drives the eccentric cam 22 and the eccentric cam 27 to move, and finally realizes that the V-groove drive block 24 pushes each large cylindrical battery in contact with the top thereof to complete an elliptical jump movement, and completes the transplantation of each large cylindrical battery between each rotating wheel of the rotating mechanism 1. Due to the coaxial drive, the coordination of the mechanism movement is very high, the vibration generated is very small, and the operation is stable.

[0042] Preferably, see Figure 3 , the four corners between the mounting plate 23 and the mounting plate 25 are respectively fixedly connected to the connecting rod 201, the connecting rod 202, the connecting rod 203 and the connecting rod 204; the middle of the mounting plate 23 is provided with an opening 2301, and the mounting plate 28 and the V-groove driving block 24 are connected to the connecting rod 205 and the connecting rod 206 through the opening 2301; through the fixed connection of each connecting rod, the action stability of the transplanting mechanism 2 is further strengthened, and it is ensured that the V-groove driving block 24 stably pushes each large cylindrical battery to complete the transplanting action. Further, the bottom plate 26 is horizontally parallel to the guide rail 261 and the guide rail 262, and the guide rail 261 is provided with at least one first slider, and one of the sliders 263 is shown in the figure. Correspondingly, the guide rail 262 is also correspondingly provided with at least one second slider, and each slider is respectively fixedly connected to the lower surface of the mounting plate 25. Through the sliding connection of multiple sliders and each slide rail, the action stability of the transplanting mechanism 2 is further strengthened, and it is ensured that the V-groove driving block 24 stably pushes each large cylindrical battery to complete the transplanting action.

[0043] According to a preferred implementation of the embodiment of the present invention, see Figure 3A support mechanism 3 is provided between the rotating mechanism 1 and the transplanting mechanism 2. The support mechanism 3 includes a support plate 31. The support plate 31 supports the mounting plate 14 of the rotating mechanism 1. An opening 311 is provided in the middle of the support plate 31. Accordingly, an opening 141 is provided in the middle of the mounting plate 14 (see Figure 5 ), the V-groove driving block 24 passes through the opening 311 and the opening 141 and is located in the space of the third spacing between the first row of rotating wheels 12 and the second row of rotating wheels 13 so as to contact and transfer each large cylindrical battery to be inspected; the support plate 31 and the bottom plate 26 are respectively fixedly connected with the support rods 301, 302, 303 and 304. The mounting plate 14 of the rotating mechanism 1 is supported by the support plate 31, the influence of the movement of the transplanting mechanism 2 is isolated, and the rotating mechanism 1 and the bottom plate 26 remain relatively still, ensuring the stability of the continuous rotation of each large cylindrical battery, thereby effectively ensuring the quality of the appearance inspection.
