[0036] A sorting and unloading device 7 is also arranged at one end of the jig transmission line 1 close to the unloading and transferring device 4 .

[0037] Continue to refer to Figures 1 to 7 As shown, in this embodiment, the fixture transmission line 1 can adopt the existing magnetic levitation transmission line with a ring structure, and the detection device 5 is provided with multiple groups (which can be set according to the detection requirements), and the detection device 5 is arranged at the detection position of the fixture transmission line 1.

[0039] The structures and working principles of the loading and unloading transfer device 3 and the unloading and unloading transfer device 4 are basically similar (the following mainly describes the principle of the loading and unloading device 3). The loading and unloading device 3 is mainly used to transfer the battery to the loading fixture 2, while the unloading and unloading device 4 transfers the battery after the inspection to the sorting and unloading device 7 for sorting and unloading; in this embodiment, the sorting and unloading device 7 includes an unloading transmission line, a tray unloading stacker arranged on one side of the unloading transmission line, a tray loading stacker arranged on one side of the tray unloading stacker, and a stacker spanning the tray unloading stacker and the tray loading stacker.

At this time, the tray transfer mechanism has transferred the empty tray from the tray loading palletizer to the tray unloading palletizer, and then the sorting robot will transfer the qualified and unqualified batteries to the corresponding areas of the tray respectively. After the tray is full, the tray unloading palletizer will unload the tray containing batteries.

[0041] In this embodiment, the loading transmission line 31 can directly adopt a conventional assembly line. The first X-axis manipulator 34 and the first Y-axis manipulator 33 both include vacuum suction nozzles. During operation, an external manipulator or an upstream assembly line transfers or transfers the battery to the loading transmission line 31. The loading transmission line 31 transfers the battery to the bottom of the first Y-axis manipulator 33. The first Y-axis manipulator 33 has a plurality of vacuum suction nozzles (the number and spacing of the vacuum suction nozzles can be set according to actual usage requirements). The first Y-axis manipulator 33 transfers the battery to the loading distance changing mechanism 32 via the vacuum suction nozzle. Subsequently, the loading distance changing mechanism 32 increases the distance between the batteries (so that the batteries can be tested separately later) and transfers them to the bottom of the first X-axis manipulator 34. Finally, the first X-axis manipulator 34 transfers the batteries after distance change to the loading fixture 2.

[0042] The feeding pitch-changing mechanism 32 comprises a first pitch-changing frame 321, a pitch-changing sliding seat 322 slidably arranged on the top of the first pitch-changing frame 321, and a pitch-changing translation mechanism 323 installed on one side of the first pitch-changing frame 321 and connected to the pitch-changing sliding seat 322; a plurality of first pitch-changing rails 324 and a plurality of second pitch-changing rails 325 are provided on the top of the first pitch-changing frame 321, and the plurality of first pitch-changing rails 324 and the plurality of second pitch-changing rails 325 are symmetrically arranged along the center line of one side of the top of the first pitch-changing frame 321; each of the first pitch-changing rails 324 and the second pitch-changing rails 325 comprises a first pitch-changing groove, a second pitch-changing groove connected to the tail of the first pitch-changing groove, and a third pitch-changing groove connected to the tail of the second pitch-changing groove; the first pitch-changing groove and the third pitch-changing groove are both provided in parallel and spaced apart along the width direction of the first pitch-changing frame 321; the second pitch-changing groove of the first pitch-changing rail 324 is inclined toward one end of the top of the first pitch-changing frame 321 Assume that (the inclination angles of the second pitch-changing grooves are different), the second pitch-changing grooves of the second pitch-changing rail 325 are inclined toward the other end of the top of the first pitch-changing frame 321 (the inclination angles of the second pitch-changing grooves are different); the top of the pitch-changing sliding seat 322 is provided with a pitch-changing slot hole along its length direction, and a plurality of pitch-changing jigs 326 for carrying the product to be tested are slidably arranged in the pitch-changing slot hole; a pitch-changing guide wheel 327 is installed at the bottom of each of the pitch-changing jigs 326 along the horizontal direction, and each pitch-changing guide wheel 327 is correspondingly arranged in a first pitch-changing groove; the top of the pitch-changing jig 326 is connected with a first profiling block 328, and the top of the first profiling block 328 is provided with a first profiling groove for loading the product to be tested; a pitch-changing guide rod 329 is also installed in the pitch-changing slot hole along its length direction, and a first linear bearing is installed on the pitch-changing jig 326, and the pitch-changing jig 326 is slidably connected to the pitch-changing guide rod 329 via the first linear bearing.

[0043] In this embodiment, the pitch-changing translation mechanism 323 includes a translation cylinder, and the number of the first pitch-changing rail 324 and the second pitch-changing rail 325 are both provided in three groups (the number of which can be set by oneself according to actual use requirements). The pitch-changing sliding seat 322 is slidably connected to the top of the first pitch-changing frame 321 via the sliding rail. The pitch-changing translation mechanism 323 can drive the pitch-changing sliding seat 322 to slide, and when the pitch-changing sliding seat 322 slides, it will drive the pitch-changing fixture 326 to slide synchronously. Since the pitch-changing guide wheel 327 of the pitch-changing fixture 326 is arranged in the pitch-changing rail and is slidably connected to the pitch-changing guide rod 329 via the first linear bearing, the pitch-changing fixture 326 will slide simultaneously in two directions along the pitch-changing rail and the pitch-changing guide rod 329. Since the second pitch-changing groove is opened at an angle, the spacings between the plurality of second pitch-changing grooves are different, so the pitch-changing fixture 326 can be changed.

[0044] In one embodiment, the loading jig 2 includes a jig connecting seat 21 connected to the jig transmission line 1, a jig loading seat connected to the jig connecting seat 21, and a carrying fixture 22 installed on the jig loading seat; the carrying fixture 22 is also provided with a first carrying slot for loading the product to be tested; the jig loading seat is also provided with a first limiting shaft 23, the first limiting shaft 23 is movably inserted into the first carrying slot from one end of the carrying fixture 22, and can rotate relative to the first carrying slot; the jig loading seat is also provided with a first positioning shaft 24, the first positioning shaft 24 is movably inserted into the first carrying slot from the other end of the carrying fixture 22, and can translate and rotate relative to the first carrying slot.

The number of loading fixtures 2 can be set according to actual usage requirements. The first fixture clamping mechanism 35 is arranged close to the battery loading position. During loading, the first fixture clamping mechanism 35 will drive the first positioning axis 24 away from the first limiting axis 23 to increase the gap between the two, so as to facilitate the first X-axis manipulator 34 to transfer the battery to the first carrying slot of the carrying fixture 22. Subsequently, the first positioning moves in the direction of the first limiting axis 23, thereby clamping the battery and limiting it. In addition, a fixture clamping mechanism is also provided at the unloading and transferring device 4, which is mainly used to drive the first positioning axis 24 away from the first limiting axis 23 to increase the gap between the two, so as to facilitate the unloading and transferring device 4 to transfer the inspected battery to the unloading transmission line.
