Compared with the manual method used in the prior art, the use of automatic sorting equipment to measure the thickness of the product and sort the product improves the efficiency of the thickness measurement and sorting of the product, and can also improve the overall production efficiency of low-temperature co-fired ceramics.

[0034] In one embodiment, see Figure 2 The thickness measuring device 4 includes a base 41, a carrying platform 42, a measuring unit 43 and a measuring drive assembly 44. The carrying platform 42 is slidably arranged on the top surface of the base 41. The carrying platform 42 is used to place the product to be measured. The measuring drive assembly 44 is arranged on the base 41, and the driving end of the measuring drive assembly 44 is connected to the carrying platform 42. The measuring drive assembly 44 is used to drive the carrying platform 42 to slide along a first direction relative to the base 41, and the measuring unit 43 is arranged on the base 41 for detecting the thickness of the product placed on the carrying platform 42.

[0035] Specifically, the base 41 refers to a supporting component with a certain volume, and the base 41 can be block-shaped or plate-shaped, etc., wherein the base 41 can be made of marble, etc., to reduce the influence of temperature on the size of the base 41. The bearing platform 42 refers to a component with a certain area, and the bearing platform 42 can be block-shaped or plate-shaped. The top of the bearing platform 42 can have a supporting surface for placing products, and the bearing platform 42 can be made of quartz material to make the supporting surface more flat, and at the same time, the influence of temperature on the flatness of the supporting surface can be reduced. A slider rail structure can be provided between the bearing platform 42 and the base 41, and a roller rail structure can also be provided.

[0036] When measuring the thickness of the product, the product can be placed on the supporting surface of the carrying platform 42 by the loading and transporting device 2, and then the thickness of the product can be measured by the measuring unit 43. In addition, the carrying platform 42 can be driven to slide relative to the base 41 along the first direction by the measuring driving component 44, so that the measuring unit 43 can measure multiple points of the product, further improving the accuracy of the thickness measurement.

[0037] In an alternative embodiment, see Figure 2 , an adsorption structure 45 for fixing the product is provided on the carrying platform 42, and the product is adsorbed on the supporting surface of the carrying platform 42 through the adsorption structure 45 to avoid the movement of the product during measurement, resulting in a hard measurement result. Specifically, the adsorption structure 45 can be a vacuum adsorption unit. For example, a vacuum chamber connected to a vacuum generating unit is provided in the block component, and a plurality of adsorption holes are provided on the block component, and the vacuum chamber is connected to the outside through the adsorption holes. The object can be adsorbed by generating negative pressure at the adsorption holes, so that the product can be fixed on the carrying platform 42 more firmly and conveniently.

[0038] In addition, a mounting groove 46 for mounting the adsorption structure 45 can be provided on the top surface of the supporting platform 42. After the adsorption structure 45 is installed in the mounting groove 46, the adsorption surface of the adsorption structure 45 remains flush with the supporting surface, thereby ensuring the adsorption of the product while avoiding the accuracy of the thickness measurement.

[0039] In one embodiment, see Figure 2The measuring unit 43 includes a spectral confocal sensor, and the number of the spectral confocal sensors is multiple, and the multiple spectral confocal sensors are arranged in sequence and spaced apart along the second direction, and the second direction is arranged at an angle to the first direction.

At the same time, multiple spectral confocal sensors are arranged in sequence and spaced apart along the second direction, so that the thickness measuring device 4 can not only measure multiple points of the product along the first direction, but also measure multiple points of the product along the second direction, which can make the thickness measurement of the product more comprehensive.

[0040] It should be noted that each spectral confocal sensor is usually composed of two measuring parts, one of which can be set above the carrying platform 42 through a bracket to detect the upper surface of the product. The other measuring part can be set below the carrying platform 42 to detect the lower surface of the product. Finally, the thickness data of the product is obtained by calculating the position difference between the upper surface and the lower surface of the product. In order to avoid the influence of the measuring part on the movement of the carrying platform 42, an avoidance groove for avoiding the measuring part is also provided on the carrying platform 42, and the length direction of the avoidance groove is set along the first direction.

[0041] In one embodiment, see Figure 1 The automatic sorting equipment also includes a measuring and transporting device 7 and a transfer support table 8.

By setting the measuring and transporting device 7 and the transfer support table 8, the arrangement position of the sorting and transporting device 5 and the unloading storage device 6 can be made more free, and the total occupied area of ​​the entire equipment can also be reduced.
