[0077] According to a second aspect of the present application, a use method of the detection equipment feeding and discharging system is provided, which is applied to the detection equipment feeding and discharging system in any of the above technical solutions. The use method comprises the following steps: placing the workpiece on the positioning suction cup assembly 124 of the feeding positioning mechanism 12; sliding the moving table 123 to drive the positioning column 13 to move, and positioning the workpiece; moving the positioned workpiece to the loading table mechanism 15 by the mechanical hand 14, and waiting for detection. The workpiece is positioned by the positioning column 13 of the feeding positioning mechanism 12, and then is carried to the loading table mechanism by the mechanical hand 14 after accurate positioning, so that the workpiece position on the loading table is accurate, and the accuracy of the detection result is improved, and the detection quality is improved.

[0078] Before the workpiece is placed on the feeding positioning mechanism 12, the workpiece is placed on the feeding buffer mechanism 16, and the workpiece is pre-positioned. The workpiece is preliminarily positioned in the feeding positioning mechanism 12 by the positioning strip 163 of the feeding positioning mechanism 12, and the position of the workpiece does not change after being carried, thereby improving the efficiency of the second positioning, and improving the detection efficiency.

[0079] Further, the inductor is installed in the feeding buffer mechanism 16, and is used to sense whether the workpiece is fed in place, so that the workpiece is fed in place before subsequent actions are performed.

[0080] Before the workpiece is placed on the feeding positioning mechanism 12, the workpiece is moved from the feeding buffer mechanism 16 to the feeding positioning mechanism 12 by the feeding carrying mechanism 17. The workpiece on the feeding buffer mechanism 16 is carried to the feeding positioning mechanism 12 by the feeding carrying mechanism 17, so that the first preliminary positioning and the second accurate positioning are carried by different mechanisms respectively, the position and the accuracy of the carrying mechanism are corrected respectively, and the workpiece can be carried to the specified position after the workpiece is positioned twice.

[0084] As another embodiment, the positioning linear module 125 drives the positioning suction disc assembly 124 to move linearly on the rack 11 to move the workpiece below the transfer suction disc assembly 144. When the feeding buffer mechanism 16 and the feeding transport mechanism 17 are not provided in the system, the workpiece positioned on the feeding positioning mechanism 12 is directly transported by the positioning linear module 125, which is more efficient and smooth in steps.

[0085] After the workpiece enters the feeding positioning mechanism 12, the extension and retraction action of the first positioning cylinder 1232 is controlled to drive the positioning column 13 to move, so that the short side of the workpiece is in contact with the positioning column 13 and the short side positioning block 1243 at the same time, and the short side of the workpiece is elastically positioned; the extension and retraction action of the second positioning cylinder 1247 is controlled to drive the long side push rod 1246 to move, and then the long side of the workpiece is in contact with the long side positioning block 1244 and the long side push block 1249 at the same time, and the long side of the workpiece is elastically positioned. By controlling the actions of the first positioning cylinder 1232 and the second positioning cylinder 1247, the positioning rod and the long side push block 1249 are brought into contact with the workpiece, respectively, to drive the workpiece to move until the workpiece is in contact with the positioning rod, the short side positioning block 1243, the long side push block 1249 and the long side positioning block 1244 at the same time, thereby realizing the function of elastically positioning the long side and the short side of the workpiece, and achieving elastic and accurate positioning of the workpiece, which can ensure the accuracy of workpiece positioning and prevent damage to the workpiece.

[0086] After the workpiece is positioned by the feeding positioning mechanism 12, the manipulator 14 moves to a position close to the feeding positioning mechanism 12, and when the transfer suction disc assembly 144 moves above the workpiece, the transfer cylinder 143 is controlled to drive the transfer suction disc assembly 144 to descend and suck the workpiece, and then the workpiece is moved to the loading table mechanism 15, and the loading table suction disc assembly is used to suck and fix the workpiece, and then detection is performed. The workpiece positioned accurately is moved to the loading table mechanism 15 by the manipulator 14 in the vertical direction and in the horizontal direction, and then detection is performed.

[0087] As another embodiment, after the workpiece is positioned by the feeding buffer mechanism 16, the feeding linear module 171 drives the feeding suction disc assembly 173 to move linearly on the rack 11, and when the feeding suction disc assembly 173 reaches above the workpiece on the feeding buffer mechanism 16, the feeding cylinder 172 and the feeding suction disc assembly 173 are controlled to act, suck and transfer the workpiece to the feeding positioning mechanism 12, and then the manipulator 14 moves the workpiece to the loading table mechanism 15, and then detection is performed. When the feeding buffer mechanism 16 and the feeding transfer mechanism 17 are provided in the system, the workpiece positioned accurately for the second time can also be moved from the feeding positioning mechanism 12 to the loading table mechanism 15 by the feeding transfer mechanism 17, and then detection is performed. The workpiece after detection is moved to the discharging mechanism 18 by the manipulator 14, and then the workpiece is discharged to the discharging position, so that the workpiece completes the feeding, detection and discharging processes in the same device, improves the continuity of the production process, and improves the production efficiency.

[0088] After the workpiece positioned is moved to the loading table mechanism 15 by the manipulator 14, and then detection is performed, the manipulator 14 moves the workpiece after detection of the loading table mechanism 15 to the discharging mechanism 18, and then the discharging mechanism 18 moves the workpiece after detection to the discharging position. After the workpiece ends detection, the manipulator 14 moves to a position close to the loading table mechanism 15, and when the transfer suction disc assembly 144 moves above the workpiece, the transfer cylinder 143 is controlled to drive the transfer suction disc assembly 144 to descend and suck the workpiece, and then the workpiece is moved to the discharging suction disc assembly 182, and the discharging suction disc assembly 182 sucks and fixes the workpiece, and then the workpiece is moved to the discharging position. The position of the workpiece after detection is unchanged, and the workpiece is moved by the manipulator 14, so that the control of the discharging precision of the workpiece is realized, the precision of the subsequent process is ensured, the continuity between processes is improved, and the production efficiency is improved.
