detailed description

The core of the present invention is to provide a detection device applied to power batteries, through the application of the present invention, the efficiency and detection accuracy of detection of power batteries will be significantly improved.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Figure 1 and Figure 2, Figure 1 is a schematic diagram of the overall structure of the present invention; Figure 2 is a schematic diagram of a partial structure of the present invention.

As shown in the figure, the detection equipment used to detect the power battery includes a plurality of detectors 1 and a transmission line 2 for transporting the power battery. There are multiple detection positions on the side of the transmission line 2, and each detector 1 They are respectively set at corresponding detection positions, and each detector 1 corresponds to a different to-be-inspected part of the power battery. The so-called side of the transmission line 2 means that the position where the detector 1 is installed is exactly the position where the detector 1 can detect the corresponding parts of the power battery to be inspected when the power battery moves to the detection position with the transmission line 2, and the side The meaning of side cannot be narrowly limited to the concept of left or right, because the installation positions of each detector 1 are aimed at different parts to be inspected on the power battery, therefore, a process is transmitted along the transmission line 2 on the same power battery In the state, during the transmission process in the direction of the arrow in Figure 1, when each detector 1 can not switch the detection position, a plurality of detectors 1 can detect different parts of the power battery to be inspected at each detection position, In this way, the detection work of all the parts to be inspected on the same power battery is completed; similarly, in the state of continuously arranging and transporting multiple power batteries on the conveying line 2, each detector 1 correspondingly performs corresponding detection of each power battery in turn. The detection of the position is completed when each power battery is output from the transmission line 2. Please note that in this process, each detector 1 points to detect a part of the power battery to be inspected, which can improve the detection accuracy. It is guaranteed and improved, and at the same time, the detection work efficiency can be improved due to avoiding the movement of the detector 1 to switch the detection position.

On the basis of the above-mentioned embodiments, the installation detection device further includes an identifier arranged at the beginning of the conveying line 2 for identifying the specification of the power battery. Calibration mechanisms 3 are respectively provided at each detection position, and the detector 1 is installed on the corresponding calibration mechanism 3, and the calibration mechanism 3 is controlled by the identifier. Thus, when a certain power battery is transported to the transmission line, the identifier identifies the power battery at the beginning of the transmission line 2, and transmits the data to each calibration mechanism 3 corresponding to the specification and model of the recognized power battery , the calibration mechanism 3 moves the detector 1 according to the preset coordinate position, so that each detector 1 moves to the corresponding position to be inspected of the power battery of the corresponding specification and model, thus, when the power battery moves to the corresponding detection position, The detector 1 for this detection position efficiently detects the power battery. It should be noted that, in this embodiment, the calibration mechanism 3 moves the position of the detector 1, not to switch the detector 1 to the position to be inspected of the power battery, but to say that each power battery has a plurality of positions to be inspected , and due to the different specifications and sizes of the power battery, the coordinate positions of the parts to be inspected are different. The calibration mechanism 3 adjusts the movement of the detector 1 to account for the differences in the position coordinates of the parts to be inspected due to differences in specifications and models. And mobile.

For the identifier, it can be further set as a scanning identifier. For power batteries with different specifications and models, the most intuitive difference lies in the difference in appearance and size. The scanning of the power battery through the scanning identifier can be easily and efficiently distinguished. Of course, in the state where labels with different specifications have been pasted or printed on the power battery, the identification and distinction can be realized by scanning the labels with a scanning identifier.

For the calibration mechanism 3 proposed in the above embodiment, according to the calibration requirements, it can be set to drive the detector 1 in translation in three vertical directions, that is, three translation drivers in vertical directions are set to drive translation. As we all know, in three-dimensional space, using the mutually perpendicular X, Y and Z coordinate systems to move can reach each coordinate position in the three-dimensional space, that is, setting the X-direction translation driver 31, the Y-direction translation driver 32 and the Z-direction translation driver 33. Therefore, the setting of the calibration mechanism 3 can move the detector 1 as required. The translation drive can be realized by using various structures such as stepping motors and worm gears. In this embodiment, for the detector 1, the detector 1 includes a light pipe 12 and an intensifier 11 as an example for illustration. As shown in FIG. The light pipe 12 and the intensifier 11 can realize the position adjustment in the three-dimensional space through the X-direction translation driver 31, the Y-direction translation driver 32 and the Z-direction translation driver 33 corresponding to their respective positions, thereby enabling the power battery to detect the irradiation All positions can be detected and irradiated.

In another embodiment, for the detection equipment proposed in this application, its conveying line 3 can be transferred from and transferred to the power battery from the main conveying line on the main production line, which means that the detecting equipment can be independent of the main conveying line Carry out the detection of the power battery, thus, set the beginning end of the transmission line 2 to connect with the main transmission line to realize the output of the power battery from the independent transmission line; at the same time, set the end of the transmission line 2 to also dock with the main transmission line to realize the transmission to the main transmission line Power Battery. The structural arrangement in this embodiment enables the produced power batteries to be tested according to testing requirements during the continuous production and delivery of power batteries. For example, a 100% full test can be performed, that is, the All the transmitted power batteries are imported into the testing equipment from the beginning of the transmission line 2 of the testing equipment, and are transported back to the main transmission line from the end of the transmission line 2 after the testing is completed. However, for example, if it is necessary to carry out detection work in the manner of 50% random inspection, then one power battery can be transported and tested every other one from the main conveying line. Of course, it is also possible to continuously transport 10 power batteries for independent detection by the detection equipment branch, and continuously release 10 power batteries from the main transmission line without detection, so as to achieve the detection index requirement of 50% random inspection.

On the basis of each of the above-mentioned embodiments, for the controller provided by the detection equipment, the controller is set to control each detector 1 separately, so that each controller can detect the power battery according to the control of the controller, or not to test. Such an arrangement enables a certain power battery to perform on-demand detection of one to-be-inspected location, two to-be-inspected locations, and multiple to-be-inspected locations, which further improves work efficiency.

Through the control connection between the controller and each detector 1, the controller can also be set to record and count the detection data obtained by the detector 1, so that the detection value of each position to be detected of a single power battery can be obtained through statistics. The deviation maximum value, deviation minimum value and average value, etc.; of course, in the continuous detection process, the average value of the same position to be inspected of multiple power batteries can also be obtained, so that it can be used to analyze the deviation of manufacturing batch power batteries, This guides the adjustment of the equipment.

Further, an extraction mechanism 4 connected to the controller can also be set on the detection equipment, and according to the comparison and judgment of the controller to the detected values, for unqualified products or power batteries that need to be detected separately, the extraction mechanism can be controlled by the controller 4. The corresponding power battery can be removed from the conveying line. This realizes the removal of the power battery whose detection value is out of tolerance.

Further, setting the extraction mechanism 4 at the end of the conveying line 2 is the optimal setting, because a plurality of detectors 1 are arranged on the conveying line 2, and the detection data detected by each detector 1 is controlled by In the state where each power battery is conveyed to the end of the conveying line 2, it can be extracted at one time by the extraction mechanism 4 as needed. Of course, the extraction mechanism 4 can also be arranged on the rear side of a certain detector 1. When the detected data of the power battery detected by the detector 1 is out of tolerance, the extraction mechanism 4 is immediately used for extraction. When the detection data detected by the detector 1 is the key detection data, such a setting can realize removal of unqualified power batteries more accurately.
