[0031] In order to explain the content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0032] See also Figures 1 to 4The present invention discloses a mounting seat inspection machine 100, which is used for the inspection of the mounting seat 200. In the present application, the mounting seat 200 includes but is not limited to the shell seat of the component of the automobile steering gear. The mounting seat 200 has two mounting surfaces, the front and the back, and its side wall 201 is roughly circular. The front of the mounting seat 200 has been installed with connectors 300, 400 and 500 of different heights for connecting with other parts of the automobile, and a sealing end cover 600. Among them, the heights of the connectors 400 and 500 are basically the same, and two plug-in sheets 301 are installed in the connector 300. In order to ensure the assembly accuracy of the four stacked wiring terminals installed on the back of the mounting seat 200 and electrically connected to the three connectors, the inductor welded to the two ends of one of the wiring terminals, and the three capacitors welded to the two ends of the other three wiring terminals in a one-to-one correspondence, the mounting seat inspection machine 100 of the present invention needs to first inspect the installation status of the three connectors. Specifically, the mounting seat inspection machine 100 of the present invention includes a turntable 10 installed on a working platform 101, a loading device 20, a height detection device 30, an inner hole detection device 40, an image detection device 50, a flipping device 60, a transparency detection device 70, a laser engraving device 80 and a unloading device 90 arranged in sequence along the transfer direction of the turntable 10, the loading device 20 is used to place the mounting seat 200 on the turntable 10 with its front side facing upward, the turntable 10 is used to convey the mounting seat 200 placed thereon, the height detection device 30 is used to detect the height of the connector 400 and the connector 500 on the mounting seat 200 and the height of the plug-in piece 301 in the connector 300, and the inner hole detection device 40 is used to detect the height after the height detection. The sizes of the inner holes of the connector 300, the connector 400 and the connector 500 are detected, the image detection device 50 is used to detect the shapes of the through holes 401 and the through holes 501 in the connector 400 and the connector 500 after the inner hole detection, the flipping device 60 is used to remove the mounting base 200 after the through hole detection from the turntable 10 and flip it 180°, and then put the mounting base 200 with the back facing up after the flipping back on the turntable 10, the transparency detection device 70 is used to detect the transparency of the side wall 201 of the mounting base 200 after the flipping, the laser engraving device 80 is used to laser code the mounting base 200 after the light transmittance detection, and the unloading device 90 is used to divert and unload the mounting base 200 after the coding is completed.

[0033] It should be noted that the mounting seat inspection machine 100 of the present invention also includes a control system, which is electrically connected to the turntable 10, the loading device 20, the height detection device 30, the inner hole detection device 40, the image detection device 50, the flip device 60, the transparency detection device 70, the laser engraving device 80 and the unloading device 90, and is used to control the coordinated actions between the various devices. Among them, the control system is an existing design, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0034] See also Figure 3 and Figure 4 , a plurality of positioning jigs 11 for fixing the mounting seat 200 are arranged along the circumference of the turntable 10, and the turntable 10 can drive the positioning jigs 11 to pass through the loading device 20, the height detection device 30, the inner hole detection device 40, the image detection device 50, the flipping device 60, the transparency detection device 70, the laser engraving device 80 and the unloading device 90 in sequence, so as to complete the corresponding actions at the workstations of the corresponding devices.

[0035] See also Figures 3 to 5 The loading device 20 includes a loading conveyor belt 21, a loading mechanism 22 and a loading claw 23 connected to the output end of the loading mechanism 22. The loading conveyor belt 21 is arranged at a loading station close to the turntable 10 and conveys the mounting seat 200 along the X-axis direction; the loading mechanism 22 is arranged between the loading conveyor belt 21 and the turntable 10, and can drive the loading claw 23 to move linearly along the Z-axis and Y-axis directions to transfer the mounting seat 200 on the loading conveyor belt 21 to the turntable 10. Among them, the feeding conveyor belt 21 is arranged along the X-axis direction, and its output end is flush with the feeding station of the turntable 10. Then, the feeding mechanism 22 can drive the feeding clamping claw 23 to move parallel to the Y-axis direction through the Y-axis driver 221 and go back and forth between the feeding conveyor belt 21 and the turntable 10, and drive the feeding clamping claw 23 to move vertically up and down to approach the mounting seat 200 through the Z-axis driver 222 connected to the output end of the Y-axis driver 221, so that the clamping driver 223 drives the feeding clamping claw 23 to clamp or release the mounting seat 200, and the moving stroke is short, which correspondingly improves the feeding efficiency. Specifically, the Y-axis driver 221, the Z-axis driver 222 and the clamping driver 223 are all linear cylinders.

[0036] See also Figure 6In addition to manually placing the mounting seat 200 on the loading conveyor belt 21, in order to further improve efficiency, in a preferred embodiment of the present application, the loading device 20 also includes a transfer mechanism 24, which is used to flip the mounting seat 200 circulating in the previous device 180° and then transfer it to the loading conveyor belt 21. The transfer mechanism 24 includes a transfer module 241 and a transfer clamp 242 connected to the output end of the transfer module 241. The X-axis driver 2411, the Y-axis driver 2412 and the Z-axis driver 2413 of the transfer module 241 drive the transfer clamp 242 to move linearly along the X-axis, Y-axis and Z-axis directions respectively, so that the clamping driver 2414 drives the transfer clamp 242 to pick up and place the mounting seat 200. The swing driver 2415 of the transfer module 241 can drive the transfer clamp 242 to swing a certain angle relative to the loading conveyor belt 21, so as to swing the mounting seat 200 from the previous device to the loading conveyor belt 21. The rotation driver 2416 of the transfer module 241 can drive the mounting seat 200 to rotate 180° relative to the loading conveyor belt 21, so that the mounting seat 200 is placed on the loading conveyor belt 21 with the front side facing up, so as to facilitate subsequent loading and detection operations.

[0037] See also Figure 7 In order to further improve the accuracy of detection, in the preferred embodiment of the present application, the feeding device 20 also includes a correction mechanism 25 installed beside the feeding mechanism 22, which is used to calibrate the horizontality of the mounting seat 200 placed on the turntable 10. The correction mechanism 25 includes a correction drive module 251, a lifting plate 252 connected to the output end of the correction drive module 251, a calibration plate 253 and a pressing plate 254 connected to the upper and lower opposite sides of the lifting plate 252, and a correction sensor 255 arranged at the rear side of the calibration plate 253. Among them, the pressing plate 254 and the calibration plate 253 are connected through a guide column 256 inserted on the lifting plate 252, and a spring 257 is sleeved on the guide column 256 between the pressing plate 254 and the lifting plate 252, and three push rods 258 arranged at 120° intervals are provided at the lower end of the pressing plate 254. The Z-axis driver 2511 of the correction drive module 251 can drive the lifting plate 252 to move linearly along the Z-axis direction, so that the three push rods 258 can abut against the three corresponding abutting ends on the mounting seat 200. Since the three push rods 258 are equidistant and equal in height, and are located at the three vertices of an equilateral triangle, the mounting seat 200 can be flattened with the push of the three push rods 258 to correct the small errors during assembly, thereby ensuring the stability of the subsequent workstations. During this process, the correction sensor 255 monitors the horizontality of the edge of the calibration plate 253 and feeds back the detection information to the control system. When the mounting seat 200 is over-tilted, one side of the product will obviously float up with the pressure, and the correction sensor 255 will send an alarm message to the control system after sensing it, so as to eliminate the abnormal situation.

[0038] See also Figure 4 , Figure 8 and Fig. 9 The height detection device 30 includes a first Z-axis driver 31 and a height measurement sensor 32 connected to the output end of the first Z-axis driver 31. The first Z-axis driver 31 can drive the height measurement sensor 32 to move linearly along the Z-axis direction, so that the reference rod 321 of the height measurement sensor 32 is inserted into the connector 400 or the connector 500 and abuts against the bottom wall of the connector 400 or the connector 500 to measure the height difference between the bottom wall of the connector 400 or the connector 500 and the corresponding top end thereof, or the reference rod 321 is inserted into the connector 300 and abuts against the top end of its plug-in sheet 301 to measure the height difference between the top surface of the plug-in sheet 301 and the top surface of the connector 300. The number of the height measurement sensors 32 can be one or two as required.

[0039] Specifically, in the preferred embodiment of the present application, two height detection devices 30 are arranged in sequence along the rotation direction of the turntable 10. When the heights of the connector 400 and the connector 500 need to be detected, in order to improve efficiency, Figure 8 As shown, two height measurement sensors 32 are respectively connected to the output end of a first Z-axis driver 31, so that they can move synchronously and complete the detection of two connectors at one time. When it is necessary to detect the height of two plug-in plates 301 in the connector 300, due to the limited space in the connector 300 and the small distance between the two plug-in plates 301, as shown in FIG. Fig. 9 As shown, a height measuring sensor 32 is connected to the output end of a first Z-axis driver 31, and the height detection device 30 also includes an X-axis driver 33. The first Z-axis driver 31 is connected to the output end of the X-axis driver 33, and the height measuring sensor 32 can move along the X-axis direction under the drive of the X-axis driver 33, thereby completing the detection of the two plug-in sheets 301 in sequence. Of course, the setting of a height measuring sensor 32 can also be used to detect the height of the connector 400 and the connector 500. Specifically, the X-axis driver 33 is a linear cylinder, and the first Z-axis driver 31 is a slide cylinder.

The second Z-axis driver 41 can drive the through gauge 44 to move linearly along the Z-axis direction, so that the through gauge 44 can be inserted into the connector 300, the connector 400 and the connector 500 to complete the detection of the corresponding inner hole. The buffer component 43 is connected between the connecting plate 42 and the through gauge 44 to prevent the through gauge 44 from moving too fast and play a buffering role, thereby protecting the connector under test. Among them, the through gauge 44 is specifically a step gauge, and the second Z-axis driver 41 is a motor or an electric cylinder. The buffer assembly 43 includes a positioning pin 431 installed at the upper end of the connecting plate 42 and abutting against the top of the through gauge 44, and a spring 432 sleeved between the positioning pin 431 and the connecting plate 42. When the through gauge 44 moves downward too fast or the pressure is too large, the through gauge 44 can slide upward along the linear slide rail 421 on the connecting plate 42, and the spring 432 is compressed, thereby playing a role of buffering and avoiding, effectively protecting the connector under test. Preferably, the inner hole detection device 40 also includes a pressure sensor 45 installed at the output end of the second Z-axis driver 41, which is used to sense the movement stroke of the second Z-axis driver 41, thereby controlling the movement of the through gauge 44.

[0041] Specifically, in order to improve efficiency, in the preferred embodiment of the present application, two inner hole detection devices 40 are arranged in sequence along the rotation direction of the turntable 10, one of which can be used for synchronous detection of the inner holes of the connectors 400 and 500, and the other is used for detection of the inner hole of the connector 300. The difference between the two inner hole detection devices 40 lies in the size and number of the through gauges 44. Of course, in other embodiments, three through gauges 44 can also be set to synchronously complete the detection of three connectors at one time.

Specifically, the X-axis driver 511, the Y-axis driver 512, and the Z-axis driver 513 are all linear motors, which are used to shoot the five through holes 401 in the connector 400 and the three through holes 501 in the connector 500, and determine the specific shape and position of the through holes according to the light transmission conditions.
