Detailed implementation mode

[0026] The following further describes the present utility model in conjunction with the accompanying drawings and implementation modes.

[0027] As Figures 1-4 shown, an IPM module appearance detection mechanism of the present utility model includes a detection table 1, a multi-station handling mechanism 2, a detection mechanism 3, and an unloading mechanism 4. The detection mechanism 3 includes an appearance detection device 31 and a pin detection device 32. The appearance detection device 31 and the pin detection device 32 are both installed on the detection table 1. The multi-station handling mechanism 2 is installed in front of the appearance detection device 31 and the pin detection device 32, and the unloading mechanism 4 is installed on the side of the pin detection device 32.

[0028] By adopting the above technical solution, by integrating the appearance detection device 31 and the pin detection device 32 on the same detection table 1, rapid and continuous detection of the IPM module can be achieved. The appearance detection device 31 can detect the surface condition of the module, such as scratches, stains, etc., while the pin detection device 32 can accurately detect whether the pins of the module are intact and whether the positions are correct. The introduction of the multi-station handling mechanism 2 enables the IPM module to be automatically handled between different detection stations without manual intervention, greatly improving the detection efficiency.

[0029] The appearance detection device 31 includes a dust-proof cover 311, an appearance detection frame 312, and a detection camera 313. The detection camera 313 is installed on the top of the appearance detection frame 312, the dust-proof cover 311 is installed below the detection camera 313, and the appearance detection frame 312 is fixed on the detection table 1.

[0030] By adopting the above technical solutions, the dust-proof cover 311 is installed below the detection camera 313, which can effectively prevent the pollution and damage of the detection camera 313 by dust, particulate matter, etc. in the production environment, ensuring the clarity and service life of the detection camera 313. Due to the protection of the dust-proof cover 311, the detection camera 313 can obtain clearer and more stable images, which is crucial for subsequent image processing and the accuracy of detection results. The appearance detection frame 312 is fixed on the detection table 1, ensuring the stability and reliability of the entire detection device.

[0031] The pin detection device 32 includes an exchange gripper 321, a pin detection station 322, and a PIN pin height detector 323. The exchange gripper 321 is installed above the pin detection station 322, and the PIN pin height detector 323 is installed behind the pin detection station 322. The exchange gripper 321, the pin detection station 322, and the PIN pin height detector 323 are installed on the detection table.

[0032] By adopting the above technical solutions, the exchange gripper 321 can automatically pick up and position the IPM module to be detected to the pin detection station 322, ensuring the accuracy and consistency of each detection. This automated operation method greatly improves the detection efficiency. The PIN pin height detector 323 can collect the data of the pin height in real time and quickly determine whether the pins are qualified by comparing with the preset standards. This efficient data processing method makes the detection results more accurate and reliable and can be timely fed back to the production line for timely adjustment and optimization of the production process.

[0033] The pin detection station 322 includes a prism camera 3221 and a module placement table 3222. The prism camera 3221 is installed on both sides of the module placement table 3222 to detect the inclination and serial number of the module on the module placement table 3222.

[0034] By adopting the above technical solutions, the prism camera 3221 is installed on both sides of the module placement table 3222 and can take pictures of the IPM module placed on the module placement table 3222 from two different angles. By analyzing these two pictures, the inclination of the module can be accurately calculated, which is crucial for ensuring the stable placement of the module during pin detection because a tilted module may lead to inaccurate pin detection. The prism camera 3221 can not only detect the inclination of the module but also read and verify the serial number on the module. The serial number is usually used to identify the uniqueness of the product. By detecting the serial number, the traceability and accuracy of the product can be ensured.

[0035] The exchange gripper 321 includes a first gripper 3211, a second gripper 3212, a first exchange wheel 3213, a second exchange wheel 3214, an exchange shaft 3215, and an exchange motor 3216. The first gripper 3211 and the second gripper 3212 are installed at both ends of the exchange shaft 3215. The exchange motor 3216 is connected to the first exchange wheel 3213. The second exchange wheel 3214 is arranged above the first exchange wheel 3213. The first exchange wheel 3213 and the second exchange wheel 3214 are connected by a belt. The exchange shaft 3215 is respectively connected to the first exchange wheel 3213 and the second exchange wheel 3214.

[0036] By adopting the above technical solution, driven by the exchange motor 3216, the exchange gripper 321 can achieve the rapid and automatic alternating operation of the first gripper 3211 and the second gripper 3212, improving the automation level of the detection process, reducing the need for manual intervention, and thus improving the detection efficiency.

[0037] The detection table 1 includes a loading seat 11, an appearance detection seat 12, a pin detection seat 13, a reserved function seat 14, and an unloading seat 15. The appearance detection seat 12, the pin detection seat 13, and the reserved function seat 14 are connected and installed on the detection table 1. The loading seat 11 and the unloading seat 15 are separately installed on the detection table 1. A push-pull cylinder 16 is arranged behind the appearance detection seat 12, the pin detection seat 13, and the reserved function seat 14. The moving direction of the push-pull cylinder 16 faces the appearance detection frame 312 and the pin detection station 322.

[0038] By adopting the above technical solution, the loading seat 11 is used to place the IPM module to be detected, and the unloading seat 15 is used to collect the detected modules. Through the movement of the push-pull cylinder 16, the module to be detected can be automatically pushed from the loading seat 11 to the appearance detection seat 12 or the pin detection seat 13 for detection, and then the detected module is pushed to the unloading seat 15, greatly improving the automation level of the detection process.

[0039] The multi-station handling mechanism 2 includes a vertical moving frame 21, a horizontal moving frame 22, and a four-station handling gripper 23. The four-station handling gripper 23 is installed on the horizontal moving frame 22. The horizontal moving frame 22 is installed on the vertical moving frame 21. The bottom of the vertical moving frame 21 is connected to the detection table 1.

[0040] By adopting the above technical solution, through the combination of the vertical moving frame 21 and the horizontal moving frame 22, the multi-station handling mechanism 2 can achieve automatic movement in both the horizontal and vertical directions, thereby automatically transporting the IPM modules to be detected or already detected from one station to another. The design of the four-station handling gripper 23 allows the mechanism to handle four stations simultaneously, significantly improving the efficiency of the detection process. In one working cycle, the mechanism can continuously pick up parts from one station, transport them to another station for detection or processing, and then transport the processed modules to the next station or the blanking seat, realizing a pipeline operation mode.

[0041] The four-station handling gripper 23 includes a handling frame 231 and module grippers 232. The bottom of the handling frame 231 is provided with mounting positions 233, the number of mounting positions 233 is 4, the number of module grippers 232 is 4, and the module grippers 232 are respectively installed on the mounting positions 233. The spacing distance of the mounting positions 233 corresponds to the spacing distance of the loading seat 11, the appearance inspection seat 12, the pin inspection seat 13, the reserved function seat 14, and the blanking seat 15.

[0042] By adopting the above technical solution, since the four-station handling gripper 23 can hold four IPM modules simultaneously, it can complete the handling process from the loading seat 11 to the appearance inspection seat 12, the pin inspection seat 13, the reserved function seat 14, and the blanking seat 15 at one time, significantly improving the continuity and efficiency of the detection process. Since the spacing distance of the mounting positions 233 corresponds to the spacing distance of each station on the detection table 1, the four-station handling gripper 23 can accurately locate to each station, ensuring that the modules can be accurately picked up and placed.

[0043] The horizontal moving frame 22 includes a horizontal moving track 221 and a horizontal moving motor 222. The horizontal moving motor 222 is connected to the horizontal moving track 221, and the handling frame 231 is installed on the horizontal moving track 221 for horizontal movement. The horizontal moving track 221 is connected to the vertical moving frame 21.

[0044] By adopting the above technical solution, the horizontal moving motor 222 can accurately control the moving distance and speed of the handling frame 231 on the horizontal moving track 221, ensuring that the handling frame 231 can accurately locate to each station on the detection table 1, thereby realizing accurate module handling.

[0045] The vertical moving frame 21 includes a vertical moving track 211 and a vertical moving motor 212. The vertical moving motor 212 is connected to the vertical moving track 211, and the horizontal moving track 221 is installed on the vertical moving track 211 for vertical movement.

[0046] By adopting the above technical solution and combining with the horizontal movement ability of the horizontal movement frame 22, the vertical movement frame 21 provides the vertical movement ability, enabling the handling frame 231 to achieve precise movement in three-dimensional space, ensuring that the handling frame 231 can accurately reach each station on the inspection table 1, whether in the horizontal direction or the vertical direction.

[0047] In the specific implementation of the present utility model, the IPM module to be detected is placed on the loading seat 11. The four-station handling gripper 23 of the multi-station handling mechanism 2 moves above the loading seat 11 through the combined movement of the vertical movement frame 21 and the horizontal movement frame 22, and the module gripper 232 grabs the IPM module on the loading seat 11.

[0048] The four-station handling gripper 23 transports the IPM module above the appearance inspection seat 12, puts down the IPM module into the dust-proof cover 311 of the appearance inspection device 31, and the inspection camera 313 performs an appearance inspection on the IPM module, such as checking for scratches, stains, etc. After the inspection is completed, the four-station handling gripper 23 picks up the IPM module from the appearance inspection seat 12.

[0049] The four-station handling gripper 23 transports the IPM module above the pin inspection seat 13.

[0050] The first gripper 3211 or the second gripper 3212 of the exchange gripper 321 grabs the IPM module and places it on the module placement table 3222. The prism camera 3221 detects the inclination and serial number of the IPM module on the module placement table 3222, and the PIN pin height detector 323 detects the pin height of the IPM module. After the inspection is completed, the exchange gripper 321 picks up the IPM module, and the first gripper 3211 and the second gripper 3212 drive the exchange shaft 3215 to exchange positions through the first exchange wheel 3213 and the second exchange wheel 3214, and place the IPM module back on the appearance inspection seat 12 to prepare for the next operation.

[0051] If the IPM module passes the inspection, the four-station handling gripper 23 transports the IPM module to the unloading seat 15; if the IPM module fails the inspection, the four-station handling gripper 23 can transport the IPM module to the reserved function seat 14 or other designated positions for further processing.

[0052] The four-station handling gripper 23 of the multi-station handling mechanism 2 can perform loading, appearance inspection, pin inspection, and unloading operations in a cycle. When picking up the previous IPM module for inspection or unloading, the front gripper can pick up the next IPM module for loading or inspection to improve the inspection efficiency.
