Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0035] In the description of this utility model, it should be understood that the terms "vertical", "horizontal", "top", "bottom", "upper", "lower", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] It should be noted that, unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] As described in the background section, existing technologies require multi-angle photography of products to achieve comprehensive product inspection. Therefore, the carrier for fixing or placing the products needs to have a certain degree of mobility to cooperate with the inspection and photography of the vision equipment. Secondly, to ensure inspection efficiency, a carrier often needs to hold multiple products and rotate or move them synchronously through a transmission device. However, as the number of products increases, the transmission accuracy of the transmission device in the existing technology decreases as it moves further away from the power source, resulting in a reduction in inspection accuracy.

[0038] For the above issues, please refer to the appendix. Figures 1-4 As shown, this utility model provides a carrier for product testing, including a base plate 34 and a first fixing plate 38 and a second fixing plate 39 disposed opposite each other on both sides of the base plate 34 along a second direction Y. A second mounting plate 33 is driven and mounted on the side of the second fixing plate 39 near the first fixing plate 38 via a coupling. In this embodiment, the second mounting plate 33 can rotate relative to the second fixing plate 39 in the central axis of the second direction Y. A first mounting plate 32 is driven and mounted on the side of the first fixing plate 38 near the second fixing plate 39. In this embodiment, the first mounting plate 32 can rotate relative to the first fixing plate 39. Plate 38 rotates axially in the second direction Y. A top plate 34 is mounted on the top of the first mounting plate 32 and the second mounting plate 33. Side plates 314 are also mounted on both sides of the first mounting plate 32, the second mounting plate 33, the top plate 34, and the side plates 314. The first mounting plate 32, the second mounting plate 33, the top plate 34, and the side plates 314 together form a mounting cavity. A third transmission assembly 36 is installed within the mounting cavity. The output end of the third transmission assembly 36 is connected to a transmission assembly 37. The transmission assembly 37 is used to mount the product and drive the product to rotate. In this embodiment, the commutator is a differential 371. In other possible embodiments, the commutator can also be a commutator.

[0039] The third transmission assembly 36 includes a second motor 361, the output end of which is connected to a second reducer 362. The output end of the second reducer 362 is provided with a first synchronous pulley 363, and a second synchronous pulley 364 is provided on the transmission shaft 373. The first synchronous pulley 363 and the second synchronous pulley 364 are connected by a first synchronous belt 365. The second synchronous pulley 364 is connected to the transmission assembly 37.

[0040] like Figures 2-3 As shown, in a further embodiment, a positioning plate 310 is installed at the end of the second mounting plate 33, and a positioning sensor 311 for detecting the positioning plate 310 is provided on the second fixing plate 39. The positioning plate sensor 311 is provided with several sets of sensors arranged at equal angles on the rotation path of the positioning plate 310.

[0041] like Figures 4-5As shown, a second drive assembly 35 is also installed in the mounting cavity. The second drive assembly 35 includes a first motor 351. A first reducer 352 is installed at the output end of the first motor 351. The fixed end of the first reducer 352 is installed on the first fixed plate 38. The first reducer 352 is also connected to the first mounting plate 32. The first motor 351 drives the transmission assembly 37 installed on the top plate 34 to rotate in the second direction Y through the first reducer 352. In this embodiment, the first reducer 352 is a harmonic reducer. Its fixed end is installed on the first fixed plate 38. The first mounting plate 32 is rotatably installed on the first reducer 352. Therefore, the first mounting plate 32, the second mounting plate 33, the top plate 34, the side plate 314, and the transmission assembly 37 installed on the top plate 34 can rotate around the second direction Y under the drive of the first reducer 315.

[0042] like Figure 6 As shown, in a further embodiment, the transmission assembly 37 includes a plurality of differentials 371. The differentials 371 are mounted below the top plate 34 along the second direction Y. The differentials 371 are mounted with drive shafts 373 along the second direction, and output shafts 374 are mounted along the third direction Z. The end of the output shaft 374 extends out of the top plate 34. The product can be mounted and fixed on the output shaft 374. Adjacent drive shafts 373 are connected by couplings 372.

[0043] Because the differentials 371 are connected via drive shafts 373, the farther a differential 371 is from the power source, the worse its rotational accuracy. To ensure that the rotational accuracy error of all differentials 371 is within an acceptable range, the power source needs to be located on the drive shaft 373 of the intermediate differential 371. Figure 6 As shown, the transmission mechanism 37 has 6 sets of differentials. Therefore, the second synchronous pulley 364 is set between the third set of differentials and the fourth set of differentials to ensure that the differential 371, which is farthest from the power source, has the smallest error caused by the transmission mechanism.

[0044] like Figures 5-6 As shown, to further improve the rotational accuracy of the differential 371, a high-precision differential 374 is selected in this embodiment, with an arc minute accuracy difference of only 3. On this differential 371, the axes of the drive shaft 373 and the output shaft 374 are not on the same plane. The ends of the drive shaft 373 and the output shaft 374 that are close to each other can be connected via... Figure 8 The hyperboloid gears shown provide a more robust direct meshing and larger contact area compared to spur gears, resulting in lower transmission errors.

[0045] like Figures 7-8As shown, this utility model also improves a device for product testing, including the aforementioned carrier 300 and a turntable 200. The carrier 300 is mounted on the turntable 200, and the bottom of the turntable 200 is provided with a first drive assembly 100 for driving the turntable 200 to rotate in a third direction Z. The carrier 300 has several groups arranged in a circular pattern at equal angles on the turntable 200. In this embodiment, the number of carriers 300 is two groups, which are mounted opposite each other on the turntable 200. In a further embodiment, the first drive assembly 100 includes a third motor 10 and a cam divider 11 that is driven by the third motor 10. The output end of the cam divider 11 is mounted on the bottom of the turntable 200, and the output end of the third motor 10 is equipped with a third synchronous pulley 12. The third synchronous pulley 12 is connected to the input end of the cam divider 11 through a second synchronous belt 13.

[0046] In this invention, the product can be placed on the output shaft 374, or a carrier plate can be set on the output shaft 374 and the product to be inspected can be placed on the carrier plate. Therefore, the output shaft 374 can drive the product to rotate to cooperate with the vision device for shooting. The product can also be rotated by the third drive component 36 to achieve multi-angle shooting, thereby improving the inspection efficiency. Furthermore, under the drive of the first drive component 100, two sets of carriers 300 set on the turntable 200, one set can be used for inspection and shooting with the vision device, and the other set is used for loading or unloading, further improving the product inspection efficiency.
