DETAILED DESCRIPTION

[0023] The utility model is further illustrated below in combination with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and not used to limit the scope of the utility model.

[0024] In combination with the drawings, Figs. 1-2 It can be seen that the overall structure of the utility model includes a product machine 1 and a feeding and discharging system 2, a conveying system 3 and a testing system 4 arranged on the product machine 1, and the conveying system 3 is located between the feeding and discharging system 2 and the testing system 4. The feeding and discharging system 2 is used to transmit the whole tray of test pieces to a material taking position. The conveying system 3 is used to take the test pieces on the material taking position one by one into the testing system 4 for testing, and put the qualified test pieces back to the tray, and the unqualified test pieces are rejected and placed in an unqualified tray. The unqualified tray is placed on the product machine 1 in advance, and the conveying system 3 can distinguish the test pieces according to the test results.

[0025] In combination with the drawings, Figs. 3-4 It can be seen that the testing system 4 includes a vertical jacking mechanism 41, a horizontal clamping mechanism 42, a testing fixture 44 and a vector net tester 5. The testing fixture 44 is vertically above the vertical jacking mechanism 41, and the horizontal clamping mechanism 42 is symmetrically arranged two on both sides of the testing fixture 44. The test piece is placed in the testing fixture 44, and is clamped and fixed by the vertical jacking mechanism 41 and the horizontal clamping mechanism 42, so that the probe is in stable contact. The testing fixture 44 is connected with the vector net tester 5 through a data transmission line, and the performance of the test piece in the testing fixture 44 is accepted and tested by the vector net tester 5. The horizontal clamping mechanism 42 is a horizontal guide rail, and the two horizontal clamping mechanisms 42 are provided with clamping blocks 43 at the opposite ends. The clamping blocks 43 can slide on the guide rail, and are provided with a cylinder. The cylinder drives the clamping blocks 43 to extend or retract. A rotary shaft 45 is arranged beside the testing fixture 44, and a downward pressing cylinder 46 is arranged on the rotary shaft 45. Through the rotation of the rotary shaft 45, the downward pressing cylinder 46 is rotated to the vertical upper side of the testing fixture 44 or is shifted. When the test piece is clamped by the left and right clamping blocks 43, the vertical jacking mechanism 41 lifts the test piece to a fixed height below the test piece. At this time, the rotary shaft 45 shifts the downward pressing cylinder 46 to the vertical upper side of the test piece, and presses downward, so that the test piece is stably clamped around.

[0026] The method for realizing the rotation of the rotating shaft 45 is that the rotating shaft is externally provided with a pneumatic cylinder or a micro motor. By setting a triggering condition, the pneumatic cylinder or the micro motor is started to work, and the lower pressing pneumatic cylinder 46 is moved to a set position, i.e. vertically above the test fixture 44. The stroke of each movement is fixed, so it is only necessary to set the triggering condition. It can be linked with the stop action of the horizontal clamping mechanism 42. When the horizontal clamping mechanism 42 stops, the rotating shaft 45 is triggered to start rotating, and after rotating to the position, the lower pressing pneumatic cylinder 46 is triggered to press the test fixture 44. Since the present patent is a utility model patent, and the focus of the application is to display the structural design, as for the internal triggering condition setting, it is a conventional electrical setting, which is not the research content of the present patent. The present patent is a mechanical design, and the structure of the linkage mechanism is designed to be completed.

[0027] The feeding and discharging system 2 will be described below. Referring to Fig. 5 The feeding and discharging system 2 comprises a tray, a conveying line and a jacking pneumatic cylinder. The test piece is placed in the tray, the tray is placed on the conveying line, and the position opposite to the carrying system is set as a material taking position. The jacking pneumatic cylinder is arranged below the material taking position. When the tray is conveyed to the material taking position, the jacking pneumatic cylinder lifts it up, separates it from the conveying line and places it on the material taking position.

[0028] A blocking plate 22 is arranged on the downstream side of the material taking position. The blocking plate 22 is provided with a pressure sensor 25 on the side facing the tray. The pressure sensor 25 is connected with the jacking pneumatic cylinder and controls the switch of the jacking pneumatic cylinder. When the tray abuts against the blocking plate, the blocking plate 22 is pressed, and the pressure sensor 25 controls the jacking pneumatic cylinder 26 to lift up.

[0029] The pressure sensor 25 is also connected with the control switch of the conveying line 21. When the tray abuts against the blocking plate 22, the blocking plate 22 is pressed, and the pressure sensor 25 controls the conveying line 21 to stop working.

[0030] Referring to the accompanying Fig. 6 , the middle part of the blocking plate 22 is provided with a rotating support point 24 with the same height as the conveying line 21. The blocking plate 22 at the lower end of the conveying line 21 is provided with a counterweight 23.

[0031] The operation process of the feeding and discharging system 2 is as follows: when the tray moves to abut against the pressure sensor 25, the jacking pneumatic cylinder 26 lifts up the tray and separates it from the conveying line 21, and synchronously triggers the control switch of the conveying line to stop working. After the tray is lifted up, the tray is not in contact with the pressure sensor 25. At this time, the conveying commands of the pressure sensor are completed (i.e. the tray is lifted up and the conveying line stops working). After the test piece on the tray is detected, the jacking pneumatic cylinder is lowered to contact the pressure sensor 25 again, the control switch of the conveying line is started, and the conveying line starts to work. The pressure sensor realizes one-time contact to start the conveying line and one-time contact to close the conveying line, and the operation is sequentially performed.

[0032] The conveying line 21 can be a belt conveyor or a chain conveyor.

[0033] The conveying system 3 comprises a four-axis robot, the end of the four-axis robot is provided with a vacuum chuck, the upper side of the vacuum chuck is provided with a vision camera, the position of the test piece is determined through the vision camera, the test piece is sucked by the vacuum chuck, and the four-axis robot is moved into the test fixture 44.

[0034] The vector network analyzer is connected with the test tool and the upper computer respectively, and test data is uploaded to the upper computer. The vector network analyzer is connected with the test tool and the upper computer respectively, and test data is uploaded to the upper computer, the upper computer stores and judges the test data, and the test data includes standing wave value, loss value and the like.

It should also be understood that terms such as those defined in a general dictionary should be understood to have meanings consistent with those in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless otherwise defined.
