[0002] During the production, manufacturing, and application processes of products such as cast films, it is necessary to measure their thickness. Since their thickness is very thin, high precision is required for measurement. In traditional measurement methods, on the one hand, manual measurement is inefficient, difficult to meet the needs of large-scale production, and the measurement results are greatly affected by human factors, making it difficult to guarantee the measurement accuracy. On the other hand, some early automated measurement devices also cannot meet the current requirements for high-precision measurement of the thickness of cast films, and cannot effectively ensure the stability and consistency of product quality.

[0051] The following further elaborates on the content of the present invention in conjunction with specific embodiments:

[0052] For ease of understanding, first describe the application scenario of this application. This application is mainly used to implement the thickness detection of cast films or other film products, and complete the full-automatic process from feeding to discharging based on the thickness detection. In this application, the cast film or other film products are defined as the workpiece to be measured 30, which can be referred to Figure 4 .

[0053] As Figure 1 shown, a sorting device includes a feeding mechanism 1, a weighing mechanism 2, a detection mechanism 3, a transfer mechanism 4, and a discharging mechanism 5; a first transfer module 6 is arranged between the feeding mechanism 1, the weighing mechanism 2, and the detection mechanism 3; a second transfer module 7 is arranged between the detection mechanism 3 and the transfer mechanism 4; a third transfer module 8 is arranged between the transfer mechanism 4 and the discharging mechanism 5.

[0054] Regarding the feeding mechanism 1;

[0055] As Figure 2 shown, the feeding mechanism 1 includes two first bins 11 and a first lifting module 13; the first bins 11 are used to enclose a space for stacking the workpieces to be measured 30, and a placing plate 12 is arranged in the first bins 11, so that the stacked workpieces to be measured 30 are carried on the placing plate 12; the two first bins 11 are installed on the same slide rail and can be driven to move synchronously, and the driving member can be a cylinder, an electric cylinder or other linear driving mechanisms. The two first bins 11 reciprocate between three stations, and thus the middle station always corresponds to a first bin 11, that is, the two first bins 11 alternately reach the middle station; thus, when any one of the first bins 11 is empty, it is replaced by another full first bin 11 for feeding, realizing uninterrupted feeding and improving work efficiency.

[0056] The first lifting module 13 is arranged below the position corresponding to the middle station and is used to lift the placing plate 12 at the corresponding station. Thus, in the case where the workpieces to be measured 30 in the first bin 11 are gradually reduced, it is always ensured that the uppermost workpiece to be measured 30 is at a constant height, facilitating the material picking of the first transfer module 6.

[0057] Regarding the weighing mechanism 2;

[0058] As Figure 3As shown in the figure, the weighing mechanism 2 and the first bin 11 at the middle working station are in the same straight line direction. The weighing mechanism 2 includes a weighing platform 21 and a limiting member 22 provided on the periphery of the weighing platform 21. After the test piece 30 is placed on the weighing platform 21, the weight of the test piece 30 can be directly feedback, and the limiting member 22 is used to abut against the outer wall of the test piece 30 to position the test piece 30, facilitating the first transfer module 6 to accurately pick up the material and transfer it to the designated position.

[0059] Regarding the detection mechanism 3;

[0060] As Figures 4 - 7 shown, the detection mechanism 3 includes a reference platform 31, a test component 32 and a driving component 33.

[0061] The upper end surface of the reference platform 31 forms a reference surface 310. There is at least one stroke space 311 in the reference platform 31. The stroke space 311 is opened in a direction perpendicular to the reference surface 310, and penetrates through the reference platform 31 at both the upper and lower ends. A calibration layer 314 is spanned on the stroke space 311; the reference surface 310 is for the test piece 30 to be attached and carried, and covers at least part of the stroke space 311; the reference platform 31, the weighing mechanism 2 and the first bin 11 at the middle working station are in the same straight line direction, facilitating the first transfer module 6 to transfer the test piece 30.

[0062] In this embodiment, multiple (for example, three) stroke spaces 311 are provided, and the length directions of the multiple stroke spaces 311 are parallel.

[0063] A plurality of embedding grooves 312 are provided in the reference platform 31. The embedding grooves 312 are opened in a direction parallel to the reference surface 310, and at least one end in the length direction penetrates through the reference platform 31 in the horizontal direction; an adsorption component 313 is embedded in the embedding groove 312. The length direction of the adsorption component 313 is parallel to the length direction of the stroke space 311, and the adsorption component 313 and the stroke space 311 are alternately and spaced apart. Combining Figure 7 shown, the lower end of the adsorption component 313 is locked and fixed on the reference platform 31 by screws. A positioning member 315 is connected to the upper end of the adsorption component 313. Two adjacent positioning members 315 press on both ends of the calibration layer 314. Based on this, in this embodiment, when three stroke spaces 311 are provided, four embedding grooves 312 and adsorption components 313 are respectively provided to ensure that both ends of each calibration layer 314 can be pressed by the positioning members 315 fixed at the upper end of the adsorption component 313.

[0064] In one embodiment, the adsorption component 313 adopts a vacuum adsorption method. Therefore, an air flow channel 318 is provided in the adsorption component 313, and an air pipe 319 is connected to its end. At this time, since at least one end of the embedding groove 312 penetrates through the reference platform 31 in the horizontal direction, the air pipe 319 can be smoothly accommodated in the embedding groove 312. Specifically refer toFigure 7 as shown

[0065] As Figure 5 , Figure 6 As shown, the test component 32 is arranged corresponding to the stroke space 311, and includes an upper test piece 321 and a lower test piece 322 which are coaxially arranged and respectively arranged on the upper and lower sides of the reference plane 310. The lower test piece 322 is accommodated in the stroke space 311; the lower test piece 322 is installed on the working platform below the reference platform 31, the upper test piece 321 is fixed on the cross beam, and each upper test piece 321 and the upper test piece 321 are installed on the output end of the fine adjustment module. The fine adjustment module includes a linear fine adjustment module 316 and / or a rotary fine adjustment module 317.

[0066] In this embodiment, as Figure 4 shown, the fine adjustment module connected to the upper test piece 321 includes a linear fine adjustment module 316 and a rotary fine adjustment module 317. The fine adjustment module is manually adjusted to realize the fine adjustment of the upper test piece 321 in a straight line direction in the vertical plane and the rotational fine adjustment along the horizontal rotation axis direction. As Figure 8 shown, the fine adjustment module connected to the lower test piece 322 includes a linear fine adjustment module 316, and by means of manual adjustment, the fine adjustment of the lower test piece 322 in a straight line direction in the horizontal plane is realized.

[0067] The driving component 33 drives the reference platform 31 and the test component 32 to move relatively, and makes the test component 32 flow through the calibration layer 314 and the component to be tested 30 relative to the reference platform 31 in sequence. As Figure 4 , Figure 8 shown, in this embodiment, the driving component 33 adopts an electric cylinder. The output end of the driving component 33 is fixedly connected to the reference platform 31. The reference platform 31 is installed on the linear guide rail, and the length direction of the linear guide rail is parallel to the length direction of the stroke space 311 / the adsorption component 313. Furthermore, based on the operation of the driving component 33, the reference platform 31 can drive the calibration layer 314 and the component to be tested 30 to move; correspondingly, the lower test piece 322 reciprocates in the stroke space 311. In other embodiments, the driving component 33 can also adopt a combination of a cylinder, a motor and a rack and pinion, or other linear driving methods.

[0068] In this application, a detection area is formed between the upper test piece 321 and the lower test piece 322. During the movement of the reference platform 31 driving the calibration layer 314 and the test piece 30 to be measured, the test assembly 32 flows through the calibration layer 314 and the test piece 30 to be measured in sequence relative to the reference platform 31. That is to say, the calibration layer 314 reaches the detection area first, and then the test piece 30 to be measured reaches the detection area. The calibration layer 314 has a rated thickness, which serves as a standard scale and provides a reliable reference basis for subsequent thickness measurement. When the upper test piece 321 and the lower test piece 322 pass through the calibration layer 314, the measured thickness of the calibration layer 314 will be obtained, and the measured thickness will be compared and analyzed with the rated thickness data of the calibration layer 314. The system can quickly calibrate and adjust the measurement accuracy of the test assembly 32; when the test piece 30 to be measured is located between the upper test piece 321 and the lower test piece 322, the test assembly 32 can accurately measure the thickness of the test piece 30 to be measured based on the previous calibration results, greatly reducing the generation of measurement errors, thereby significantly improving the accuracy of measuring the thickness of the test piece 30 to be measured.

[0069] Regarding the transfer mechanism 4;

[0070] As Figure 9 shown, the transfer mechanism 4 is arranged on the side of the reference platform 31 and includes a transfer platform 41. A limiting member 22 is arranged on the periphery of the transfer platform 41. The limiting member 22 is used to abut against the outer contour of the product (the test piece 30 to be measured that has completed the detection) to realize the positioning of the product and facilitate the accuracy of subsequent material taking. In this embodiment, an ion blower 42 is arranged on the side of the transfer mechanism 4 to eliminate the static electricity on the surface of the product.

[0071] Regarding the blanking mechanism 5;

[0072] As Figure 9 shown, the blanking mechanism 5 includes a plurality of second bins 51 and a second lifting module 52. A second lifting module 52 is correspondingly arranged below each second bin 51. The second bins 51 enclose a space for stacking products. A placement plate 12 is arranged in the second bin 51, and the stacked products are carried on the placement plate 12; the output end of the second lifting module 52 is connected to the placement plate 12 in the corresponding second bin 51 and is used to sink the corresponding connected placement plate 12. Thus, when the products in the second bin 51 are gradually stacked, the topmost product is always kept at a constant height, which is convenient for the third transfer module 8 to discharge materials.

[0073] In this embodiment, four second bins 51 are arranged to stack products in different thickness ranges after thickness detection, which is convenient for the application of subsequent processes; of course, the second bins 51 can also be arranged in other quantities.

[0074] Based on the above arrangements of the feeding mechanism 1, weighing mechanism 2, detection mechanism 3, transfer mechanism 4 and discharging mechanism 5, they perform actions independently. However, the transfer of the workpiece 30 / product to be measured between various mechanisms requires the transfer module to perform actions. Therefore, the first transfer module 6, the second transfer module 7 and the third transfer module 8 are provided.

[0075] As Figure 3 shown, the first transfer module 6 is arranged between the feeding mechanism 1, weighing mechanism 2 and detection mechanism 3; there are two first picking modules 61 on the first transfer module 6, and the two first picking modules 61 reciprocate between the feeding mechanism 1 and the weighing mechanism 2, and between the weighing mechanism 2 and the detection mechanism 3 respectively; that is to say, when one of the first picking modules 61 transfers the workpiece 30 in the feeding mechanism 1 to the weighing mechanism 2, the other first picking module 61 transfers the workpiece 30 on the weighing mechanism 2 to the detection mechanism 3, with coordinated and efficient pace.

[0076] The second transfer module 7 is arranged between the detection mechanism 3 and the transfer mechanism 4, and there is a second picking module 71 on the second transfer module 7, and the second picking module 71 reciprocates between the detection mechanism 3 and the transfer mechanism 4.

[0077] The third transfer module 8 is arranged between the transfer mechanism 4 and the discharging mechanism 5, and there is a third picking module 81 on the third transfer module 8, and the third picking module 81 reciprocates between the transfer mechanism 4 and the discharging mechanism 5.

[0078] During operation, the first transfer module 6 takes out the workpiece 30 in the first bin 11 and places it on the weighing platform 21. After weighing on the weighing platform 21, another first picking module 61 on the first transfer module 6 transfers the workpiece 30 on the weighing platform 21 to the reference platform 31, and after moving with the reference platform 31, the thickness detection is completed; then the second transfer module 7 places the product that has been detected on the reference platform 31 on the transfer platform 41. After positioning by the transfer platform 41, finally it is transferred to the corresponding second bin 51 by the third transfer module 8.

[0079] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
