Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation detection, in particular to a rotary table detection platform. BACKGROUND

[0002] Touchpad is an input device that can move the cursor by sliding the finger on the smooth touchpad. It is the most widely used notebook computer mouse. Because the thickness of the touchpad is very thin, about 0.5mm, it can be designed in the ultra-thin notebook computer or keyboard.

[0003] As a precision accessory of notebook computer and other terminals, the touchpad needs to be detected before being assembled in these terminals, including but not limited to the detection of the overall flatness, the four peripheral shape sizes and the stud profile of the touchpad.

[0004] The existing touchpad detection production line includes processes such as feeding, conveying, detecting and discharging. The feeding process is completed by a feeding device, and the detection process is completed by a detection device. The detection device generally includes a detection piece, a bearing piece and a detection movement assembly. The bearing piece is used to bear the touchpad to be detected. The bearing piece is arranged at the output end of the detection movement assembly. The bearing piece is driven by the detection movement assembly to reciprocate below the detection piece, and the edge to be detected is changed every time. If the touchpad includes four edges, the detection movement assembly needs to drive the bearing piece to rotate the touchpad four times to detect the four edges respectively. This design integrates multiple detection functions in one detection device, but the touchpad needs to be moved multiple times to cooperate with the detection device to complete the detection of different items, resulting in long detection time and low detection efficiency. SUMMARY

The at least two loading members are sequentially arranged at the edges of the rotary table along the circumference of the rotary table. The rotary table driving member is used to drive the rotary table to rotate, so that any loading member can sequentially flow between the feeding and discharging stations and the detection stations. When any loading member is opposite to the feeding and discharging stations or any detection station, the remaining loading members are respectively opposite to the other stations one by one.

[0009] A detection module corresponding to each detection station is arranged, each detection module comprising a driving mechanism and a detection mechanism, the driving mechanism is arranged on the workbench, and the driving mechanism is used to drive the detection mechanism to move relative to the loading piece, and the detection mechanism comprises a camera or a laser.

[0036] The present embodiment provides a rotary table detection platform for detecting workpieces, wherein the workpieces can be touch panels 700 of notebook computers. The rotary table detection platform comprises a workbench 100, a transfer module 200, a first detection module 300, a second detection module 400 and a third detection module 500, the touch panels 700 are arranged on the transfer module 200, the transfer module 200 drives the touch panels 700 to sequentially flow between the first detection module 300, the second detection module 400 and the third detection module 500, and when any touch panel 700 is at a position opposite to any detection module, the other detection modules correspond to a touch panel 700, so that each detection module can synchronously perform detection work, improving the detection efficiency.

[0037] Please refer to Figure 1 and Figure 2 The workbench 100 is sequentially provided with a feeding and discharging station 101, a first detection station 102, a second detection station 103 and a third detection station 104, and the feeding and discharging station 101, the first detection station 102, the second detection station 103 and the third detection station 104 are arranged in a ring shape.

[0038] The transfer module 200 is arranged on the workbench 100. The transfer module 200 comprises a rotating disc 201, a rotating disc driving member 109, and four loading members 202 arranged in sequence along the circumference of the rotating disc 201 at the edge of the rotating disc 201. The rotating disc driving member 109 is used to drive the rotating disc 201 to rotate, so that any loading member 202 can be transferred in sequence between the feeding and discharging station 101, the first detection station 102, the second detection station 103, and the third detection station 104. When any loading member 202 is opposite to any station, the remaining three loading members 202 are opposite to the other three stations respectively. In this way, each station can be operated synchronously, improving the utilization rate of the equipment and the detection efficiency.

[0039] The workbench 100 is provided with four mounting grooves 105, and each mounting groove 105 is provided with a jig plate 106. The loading member 202 can be unloaded and mounted on the jig plate 106. The loading member 202 comprises a jig 203 used for fixing the touch panel 700.

[0040] Please refer to Figure 4 and Figure 5 Each loading member 202 comprises the jig 203, a first positioning assembly, and a second positioning assembly. The jig 203 is arranged on the jig plate 106. The jig 203 is provided with a containing groove 216 for placing the touch panel 700. The bottom of the containing groove 216 is provided with a detection through hole 217 matched with the contour to be detected on the touch panel 700. When the touch panel 700 is placed in the containing groove 216, at least part of the contour of the touch panel 700 is exposed from the detection through hole 217. In this way, a camera can shoot a clear image of the touch panel 700 from below to perform appearance detection.

[0041] The first positioning assembly comprises a first air cylinder 204 and a first push block 205. The first air cylinder 204 is fixed on the jig plate 106 and can drive the first push block 205 to move close to or away from the touch panel 700 on the jig 203. The second positioning assembly comprises a second air cylinder 210 and a second push block 211. The second air cylinder 210 is fixed on the jig plate 106 and can drive the second push block 211 to move close to or away from the touch panel 700 on the jig 203. The movement direction of the second push block 211 relative to the jig 203 is perpendicular to the movement direction of the first push block 205 relative to the jig 203. The first positioning assembly and the second positioning assembly are used to limit the adjacent two sides of the touch panel 700 respectively, which can prevent the touch panel 700 from shifting during the rotation of the rotating disc 201, and is conducive to improving the image acquisition accuracy.

[0042] In a possible implementation, to avoid interference of the first and second positioning assemblies with the feeding and discharging, the first positioning assembly is arranged close to the center of the turntable 201 and away from the edge of the turntable 201, and the second positioning assembly is arranged on the left or right side of the first positioning assembly, on the side opposite to the first positioning assembly and close to the edge of the turntable 201, so as to have no obstruction and have sufficient feeding and discharging operation space.

[0043] In a possible implementation, the turntable 201 has a disc-shaped structure, and has limited length and width space. To reduce the length and width space occupied by the positioning assemblies and improve the utilization of the turntable 201, the first and second positioning assemblies are arranged side by side instead of being directly pushed by the cylinders to limit the positions of the push blocks, so as to reduce the length of the positioning assemblies.

[0044] Please refer to Figure 4 , the first positioning assembly includes a first cylinder 204, a first push block 205, a first transition plate 206, a first push block fixing member 207, a first spring 208, and a first stop block. The first stop block is fixed on the jig plate 106, the first transition plate 206 is located between the first stop block and the first cylinder 204, the piston rod of the first cylinder 204 is connected to the first transition plate 206, the first transition plate 206 is connected to the first push block fixing member 207 through the first spring 208, the first push block 205 is fixed on the first push block fixing member 207, and the bottom of the first push block fixing member 207 is in sliding connection with the first transition plate 206. The first transition plate 206 can drive the first push block 205 to extend and retract under the driving action of the first cylinder 204, and the movement direction of the first push block 205 is the same as that of the piston of the first cylinder 204. The second positioning assembly includes a second cylinder 210, a second push block 211, a second transition plate 212, a second push block fixing member 213, a second spring 214, and a second stop block. The second stop block is fixed on the jig plate 106, the second transition plate 212 is located between the second stop block and the second cylinder 210, the piston rod of the second cylinder 210 is connected to the second transition plate 212, the second transition plate 212 is connected to the second push block fixing member 213 through the second spring 214, the second push block 211 is fixed on the second push block fixing member 213, and the bottom of the second push block fixing member 213 is in sliding connection with the second transition plate 212. The second transition plate 212 can drive the second push block 211 to extend and retract under the driving action of the second cylinder 210, and the movement direction of the second push block 211 is the same as that of the piston of the second cylinder 210.

[0045] As known from the foregoing, the present embodiment is provided with the detection through hole 217 on the jig 203. When the touch panel 700 is arranged on the jig 203, the profile of the part of the touch panel 700 to be detected can be exposed from the detection through hole 217. When the detection device collects images from above or below the touch panel 700, the images of the upper and lower surfaces of the touch panel 700 can be obtained, but the image of the side surface of the touch panel 700 cannot be obtained. To solve this problem, the present embodiment is provided with the prism 220 to transfer the image of the side surface of the touch panel 700, so that the detection device can obtain the image of the side surface of the touch panel 700 from above or below the touch panel 700. For details, please refer to Figure 4 and Figure 5 The detection through hole 217 includes a side direction detection through hole 218 corresponding to the side surface of the touch panel 700. The jig 203 is provided with a prism mounting seat 219 near the side direction detection through hole 218. The prism mounting seat 219 is provided with the prism 220. The prism 220 is located in the side direction detection through hole 218 and is used to refract the image of the side surface of the touch panel 700 to the upper or lower side of the turntable 201.

[0046] Please refer to Figure 3 The workbench 100 is fixed with a driving member mounting seat 107. The turntable driving member 109 is fixed on the driving member mounting seat 107. The output shaft of the turntable driving member 109 is connected to the turntable 201. The transfer module 200 further includes a vacuum suction assembly, a support frame 221 and an electric slip ring 222. The vacuum suction assembly includes a vacuum generator 223, a plurality of first vacuum nozzles 224 and a plurality of second vacuum nozzles.

The second vacuum nozzles are arranged on the lower surface of the jig plate 106 and are used to suck the lower surface of the jig 203. The vacuum generator 223 is fixed on the workbench 100. The vacuum generator 223 is connected to the first vacuum nozzles 224 and the second vacuum nozzles respectively and is used to provide suction force for the first vacuum nozzles 224 and the second vacuum nozzles. The lower end of the support frame 221 is fixed on the workbench 100. The upper end of the support frame 221 extends to the upper side of the turntable 201. The electric slip ring 222 is located on the upper side of the turntable 201. The fixed ring of the electric slip ring 222 is connected to the upper end of the support frame 221. The rotating ring of the electric slip ring 222 is connected to the turntable 201. The electric slip ring 222, the turntable 201 and the output shaft of the turntable driving member 109 are coaxially arranged. Vacuum pipes, power lines and signal lines can be connected to the corresponding devices through the electric slip ring 222. The line layout specification can make the surface of the workbench 100 clean and prevent the cables from being entangled.

[0047] The first detection module 300 is arranged at the first detection station 102. The first detection module 300 comprises a pressing column 301, a pressing mechanism 303, a first driving mechanism and a first detection mechanism. The pressing column 301 is fixed to the workbench 100. The pressing mechanism 303 is in sliding connection with the pressing column 301. The pressing mechanism 303 is used to apply a pressing force to the touch panel 700 on the jig 203 so as to keep the touch panel 700 flat. The first driving mechanism is arranged on the workbench 100 and can drive the first detection mechanism to move relative to the touch panel 700. The first detection mechanism comprises a first camera 302 arranged below the workbench 100. The first camera 302 is used to detect the outer dimensions of the touch panel 700.

[0048] Please refer to Figure 6 The pressing mechanism 303 is arranged above the turntable 201 and comprises a pressing plate 304, a pressing driving element 305 and a plurality of pressing heads 306. The pressing plate 304 is in sliding connection with the pressing column 301. The pressing heads 306 are fixed to the pressing plate 304. The pressing driving element 305 is arranged on the pressing column 301 and is used to drive the pressing plate 304 to move close to or away from the touch panel 700. The pressing heads 306 are used to abut against the upper surface of the touch panel 700. The pressing heads 306 are made of soft rubber and will not damage the surface of the touch panel 700. The plurality of pressing heads 306 abut against the upper surface of the touch panel 700, so that the touch panel 700 can be kept flat. The touch panel 700 is a thin-walled part with a thickness of about 0.5 mm. When the touch panel 700 is placed flat on the jig 203, the touch panel 700 may be warped due to its own deformation or the clamping action of the first positioning assembly and the second positioning assembly. The warping will affect the measurement accuracy. Therefore, the touch panel 700 needs to be kept flat by the pressing mechanism 303. When the pressing mechanism 303 is used to apply a pressing force to the warped touch panel 700, the edges of the touch panel 700 abut against and apply a pushing force to the first push block 205 and the second push block 211 when the touch panel 700 is unfolded. Under the action of the pushing force, the first push block 205 causes the first spring 208 to compress and deform, and the second push block 211 causes the second spring 214 to compress and deform, so that the touch panel 700 is limited on the side surface and the upper and lower surfaces and kept flat.

[0049] In one possible implementation, a scanning gun is further arranged on the pressing column 301. The scanning gun can be used to detect the profile of the stud on the upper surface of the touch panel 700. The scanning gun in cooperation with the first camera 302 can detect the profiles of the upper surface and the lower surface of the stud on the touch panel 700, so that the detection is more comprehensive.

[0050] In a possible implementation, the turntable 201 is further provided with a calibration plate mounting hole 108, and a calibration plate 600 is arranged at the calibration plate mounting hole 108, and the calibration plate 600 is provided with a plurality of calibration holes 601; the turntable 201 can drive the calibration plate 600 to rotate to be opposite to the first detection module 300, the second detection module 400 and the third detection module 500. The calibration plate 600 can be used for spatial coordinates of the same three detection modules. Specifically, the calibration plate 600 is rotated to the positions of the first detection module 300, the second detection module 400 and the third detection module 500 respectively, the first detection module 300 collects first coordinate data of the calibration holes 601 on the calibration plate 600, the second detection module 400 collects second coordinate data of the calibration holes 601 on the calibration plate 600, and the third detection module 500 collects third coordinate data of the calibration holes 601 on the calibration plate 600; by corresponding the first coordinate data, the second coordinate data and the third coordinate data, a difference between the data can be found, and the images acquired by the detection modules are brought into the difference for calculation, so that the images acquired by the detection modules can be unified in the same coordinate system, so that comprehensive detection data can be obtained conveniently.
