[0020] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0021] like Figures 1 to 4 As shown, the present invention discloses an automatic VC temperature equalizing plate flatness detection machine 100, which detects the flatness of the VC temperature equalizing plate in a non-contact manner, reduces the quality risk caused by frequent manual contact with the product, and reduces the risk of crushing the VC temperature equalizing plate.

[0022] The VC temperature equalizing plate flatness automatic inspection machine 100 of the present invention comprises a loading device 10, a picking and unloading device 20, a code scanning device 30, a rotating platform device 40, a laser detection device 50 and a sorting and unloading device 60. The loading device 10, the picking and unloading device 20, the code scanning device 30, the rotating platform device 40, the laser detection device 50 and the sorting and unloading device 60 are arranged in sequence along the flow direction of the VC temperature equalizing plate. The picking and unloading device 20 is used to grab the VC temperature equalizing plate at the loading device 10 to the code scanning device 30 and to grab the VC temperature equalizing plate at the code scanning device 30 and put it into the rotating platform device 40. The code scanning device 30 comprises a material detection sensor 31 and a code scanning gun 32. The code scanning gun 32 reads the identity information of the VC temperature equalizing plate to be inspected when the material detection sensor 31 is triggered. The rotating platform device 40 is used to send the VC temperature balancing board to the laser detection device 50. The laser detection device 50 is used to detect the flatness of the VC temperature balancing board. The sorting and unloading device 60 sorts the VC temperature balancing board according to the detection result.

[0023] In the present invention, a barcode scanning device 30 is used to read the VC temperature equalizing board to be tested to obtain the identity information of the VC temperature equalizing board. After the laser detection device 50 performs flatness detection on the VC temperature equalizing board, the sorting and unloading device 60 can sort the corresponding VC temperature equalizing board. Because the identity information of the VC temperature equalizing board corresponds to the detection result one by one, after the flatness detection, it can be immediately known whether the flatness of a certain VC temperature equalizing board is poor, so that the flatness can be fully automatically detected without manual monitoring of the detection results and making corresponding sorting actions, thereby reducing work intensity and reducing the risk of errors.

[0024] like Figure 1 and Figure 2As shown, the material taking and placing device 20 of the present invention is arranged directly above the code scanning device 30, so as to optimize the layout and carry the VC temperature equalizing plate. Preferably, the material detection sensor 31 and the code scanning gun 32 are arranged in conjunction. After the material detection sensor 31 detects that the VC temperature equalizing plate is placed, the code scanning gun 32 then reads the identity information of the VC temperature equalizing plate to realize automatic reading of the identity information. More specifically, the code scanning gun 32 obtains the identity information of the VC temperature equalizing plate by reading the QR code, barcode, number, character, pattern or picture on the VC temperature equalizing plate. It is worth noting that the identity information of each VC temperature equalizing plate is independent and unique.

[0025] like Figure 1 and Figure 2 As shown, the feeding device 10 includes a feeding motor 11 and a feeding fixture 12. The feeding fixture 12 is installed at the output end of the feeding motor 11, and the feeding motor 11 drives the feeding fixture 12 to slide along the Z axis. Specifically, the VC temperature plate is placed in the feeding fixture 12, and the feeding motor 11 drives the feeding fixture 12 to slide along the Z axis from bottom to top to perform sequential feeding.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the rotating platform device 40 includes a turntable 41 and a positioning fixture 42 installed on the top of the turntable 41. The positioning fixture 42 has at least a loading station, a detection station and a unloading station. The rotation of the turntable 41 drives the positioning fixture 42 to continuously switch between the loading station, the detection station and the unloading station. When the positioning fixture 42 is at the loading station, the VC temperature equalizing plate to be tested is placed on the positioning fixture 42, and the rotation of the turntable 41 drives the positioning fixture 42 to switch to the detection station. The laser detection device 50 performs a flatness detection on the VC temperature equalizing plate. Then, the rotation of the turntable 41 drives the positioning fixture 42 to switch to the unloading station, and the sorting and unloading device 60 sorts the VC temperature equalizing plate according to the detection results.

[0027] Furthermore, a plurality of positioning fixtures 42 are installed on the top of the turntable 41. The turntable 41 has a rotation centerline (not shown. In this embodiment, the rotation centerline coincides with the structural centerline of the turntable 41). The turntable 41 rotates around the rotation centerline. The plurality of positioning fixtures 42 are arranged alternately at equal angles around the rotation centerline on the top of the turntable 41. By providing a plurality of positioning fixtures 42, a plurality of VC temperature averaging plates can be loaded at the same time, thereby improving the detection efficiency.

[0028] Furthermore, the VC temperature equalizing plate flatness automatic inspection machine 100 of the present invention also includes a vacuum pipe 70, which is suitable for connecting with a vacuum generating device, and the positioning fixture 42 is provided with a structural positioning groove 421 for placing the VC temperature equalizing plate, and the structural positioning groove 421 is connected with the vacuum pipe 70. After the VC temperature equalizing plate is placed in the structural positioning groove 421, the vacuum generating device evacuates the structural positioning groove 421 through the vacuum pipe 70, so that the structural positioning groove 421 generates negative pressure, so that the VC temperature equalizing plate is stably positioned in the structural positioning groove 421, and the accuracy of the detection result is ensured. Among them, the vacuum generating device can adopt the existing structure. The vacuum pipe 70 can adopt structures such as a hose and a metal pipe.

[0029] like Figure 1 and Figure 3 As shown, the laser detection device 50 includes a line laser detection module 51 and a moving module 52. The line laser detection module 51 is installed at the output end of the moving module 52, and the moving module 52 drives the line laser detection module 51 to slide in the X-axis.

[0030] The line laser detection module 51 of the present invention detects the flatness of the VC temperature equalizer by line laser detection (using the least square method to calculate the flatness result, but not limited to this). The laser line emitted by the line laser (using 2D or 3D equipment) irradiates the surface of the VC temperature equalizer. The camera captures the emitted light on the surface of the VC temperature equalizer to form a line. The curvature of the laser line is analyzed by image processing technology, so as to accurately measure the height of the surface of the VC temperature equalizer. The measured data is statistically analyzed to determine whether the surface of the VC temperature equalizer meets the flatness requirements. In addition, the use of line laser detection can reduce the risk of crushing the product due to contact with the product.

[0031] like Figure 1 and Figure 4 As shown, the sorting and unloading device 60 includes a sorting X-axis 61, a sorting Y-axis 62, a material picking suction cup 63 and a sorting material box 64. The sorting X-axis 61 is installed at the output end of the sorting Y-axis 62, the material picking suction cup 63 is installed at the output end of the sorting X-axis 61, the sorting Y-axis 62 drives the sorting X-axis 61 to slide in the Y-axis, the sorting X-axis 61 drives the material picking suction cup 63 to slide in the X-axis, and the sorting material box 64 is arranged on one side of the rotating platform device 40. The sorting X-axis 61 and the sorting Y-axis 62 drive the material picking suction cup 63 to slide in the XY direction, and according to the test results, the corresponding VC temperature equalizing plate is placed in the sorting material box 64. For example, the qualified VC temperature equalizing plate can be placed in the sorting material box 64, and the unqualified ones can be sent out. Of course, the unqualified VC temperature equalizing plate can also be placed in the sorting material box 64, and the qualified ones can be sent out. Alternatively, the VC temperature equalizing plates that have passed the test may be placed in a certain (or several) specific spaces of the sorting box 64 , and the VC temperature equalizing plates that have failed the test may be placed in other spaces of the sorting box 64 .

[0032] like Figure 1 and Figure 2 As shown, the material picking and unloading device 20 adopts a PPU manipulator, and a plurality of material picking and unloading suction cups 21 are installed at the output end of the PPU manipulator. Grasping the VC temperature averaging plate by the material picking and unloading suction cups 21 can greatly reduce the damage to the VC temperature averaging plate, and the PPU manipulator can quickly and effectively transfer materials.

[0033] In addition, the VC temperature equalizing plate flatness automatic inspection machine 100 of the present invention is also provided with a human-computer interaction interface (having a display module, such as a liquid crystal display screen), through which the working conditions, inspection results, etc. can be understood. In addition, the operation of the equipment can be controlled through buttons such as "start", "stop", "emergency stop", and "power".

[0034] The following is a brief introduction to the working process of the VC temperature equalizing plate flatness automatic detection machine 100 of the present invention: the VC temperature equalizing plate is placed on the loading fixture 12, the loading motor 11 drives the loading fixture 12 to slide from bottom to top on the Z axis, the material taking and discharging device 20 takes away the VC temperature equalizing plate, and sends the taken VC temperature equalizing plate to the code scanning device 30, after the material detection sensor 31 detects that the VC temperature equalizing plate is put in, the code scanning gun 32 reads the identity information of the VC temperature equalizing plate. Next, the material taking and discharging device 20 takes away the VC temperature equalizing plate from the code scanning device 30, and then puts the taken VC temperature equalizing plate on the positioning fixture 42 at the loading station. The turntable 41 rotates to drive the positioning fixture 42 to the detection station, and the moving module 52 drives the line laser detection module 51 to slide on the X axis, and the line laser detection module 51 performs flatness detection on the VC temperature equalizing plate. According to the detection results, the sorting X-axis 61 and the sorting Y-axis 62 drive the material picking suction cup 63 to slide in the XY direction, and the material picking suction cup 63 sucks the VC temperature averaging plate and puts the VC temperature averaging plate into the corresponding space of the sorting material box 64.

[0035] Figure 1 , Figure 2 , Figure 3 and Figure 4 , the direction indicated by arrow X is the X-axis direction, the direction indicated by arrow Y is the Y-axis direction, and the direction indicated by arrow Z is the Z-axis direction.

[0036] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
