Each block is provided with two test bars 203, the two test bars 203 are positioned in the same plane and parallel to the sliding rail, and when the test bars 203 reciprocate, the ends of the test bars 203 are abutted against the edges of the product batteries. Two sides of the detection reference platform 201, which are close to the end of the test rod 203, are not provided with flanges 202, and the other two sides are provided with flanges 202. When the test lever 203 is pushed toward the product battery, the product battery is pushed against the flange 202, and the flange 202 limits the product battery, thereby obtaining reliable dimensional parameters.

After the parameters are obtained, the product batteries are grabbed and sent to the temporary storage platform 301 through the clamping jaw 109, and the defective product cutting and arranging assembly 3 on the side edge of the temporary storage platform 301 pushes the product batteries into the corresponding length defect collecting section 305 or width defect collecting section 306 according to the long-side defects or short-side defects.

As shown in fig. 5 and 6, the specific structure for pushing the defective product battery includes a sliding rail disposed at the side of the defective product collecting tank, and a temporary storage platform 301 is slidingly connected to the sliding rail. A push cylinder 302 is fixedly installed on the temporary storage platform 301, and a push block chute 304 is correspondingly arranged at a piston rod of the push cylinder 302 so as to push out the product battery along the push block chute 304 in a straight line. Since the upper ends of the length defect collecting section 305 and the width defect collecting section 306 are connected with each other, the defect products can be correspondingly collected according to the defect types only by adjusting the relative positions between the temporary storage platform 301 and the length defect collecting section 305 and the width defect collecting section 306.

the product battery is put into the carrier on the material loading conveyer belt 6, and the carrier is carried product battery to detection benchmark platform 201 department, and through clamping jaw 109 centre gripping product battery, put on the detection benchmark platform 201, after the sensor in corresponding position detected the product battery, the measuring stick stretches out, detects long limit and the minor face of product battery respectively.

After the detection is completed, the measuring rod retreats to a waiting position, and meanwhile, the system judges, screens, records and stores data.

When the carrier on the feeding conveyor belt 6 brings the next product battery into place, the motor 103 turns over to move the clamping jaw 109 of the transfer device 5, such as the leftmost clamping jaw 109 in the figure to clamp the product battery in the carrier, and the middle clamping jaw 109 clamps the product battery which is tested on the detection reference platform 201; then the motor 103 rotates positively, and the tested product batteries are sent to the defect product cutting assembly 3 and fall on the temporary storage platform 301; the product battery to be detected falls on the detection reference platform 201 and is ready for detection.

After the sensor at the defective product cutting and arranging assembly 3 detects the product battery, the motor 103 reverses, and moves to the waiting position again to wait for the next clamping. Meanwhile, according to the measured result, if there is a defect in the long side dimension of the product battery, the product battery needs to be pushed into the length defect collecting section 305, which comprises the following specific processes: the pushing block 303 corresponds to the length defect collecting section 305, and the piston rod of the pushing cylinder 302 extends out to push the product battery on the temporary storage platform 301 into the length defect collecting section 305. If there is a defect in the short side dimension, the pushing block 303 moves to the position of the width defect collecting section 306, and the piston rod of the pushing cylinder 302 extends out to push the product battery into the width defect collecting section 306.

If the product size is qualified, the pushing cylinder 302 does not move, the motor 103 rotates forward, the rightmost clamping jaw 109 clamps the product battery on the temporary storage platform 301, the middle clamping jaw 109 clamps the product battery on the detection reference platform 201, the leftmost clamping jaw 109 clamps the product battery on the carrier, the three product batteries move to one station in the feeding direction at the same time, namely, the qualified product battery is placed at the position of the qualified product conveyor belt 7, the detected product battery is placed on the temporary storage platform 301, and the product battery on the carrier is placed on the detection reference platform 201. After the placement is completed, the motor 103 drives the clamping jaw 109 to reset.

And the product batteries on the qualified product conveyor belt 7 are conveyed along with the conveyor belt, meanwhile, the camera reads the two-dimensional codes on the product batteries, the system compares, judges, records and stores the read two-dimensional codes, if the two-dimensional codes are wrong, the piston rod of the air cylinder positioned at the side edge of the qualified product conveyor belt 7 extends out, and the product batteries positioned on the qualified product conveyor belt 7 are pushed out of the conveyor belt and fall into the collecting container. And if the two-dimensional code is correct, outputting the qualified product battery to the next engineering equipment through the qualified product conveyor belt 7.

Compared with the traditional battery measurement and two-dimension code information comparison, the device almost does not need to be manually participated in the whole process, and the product quality and stability are greatly improved by combining the efficient servo motor 103, the electric cylinder, the two-dimension code reader, the conveying line and the special clamp, so that the labor intensity is greatly saved, the labor intensity is reduced, and the economic benefit is improved. And good data recording to facilitate future process traceability.
