each battery accommodating groove 102 is used for vertically accommodating a battery, and the top of the battery is provided with a positive pole and a negative pole;
the battery tray 1 is provided with a vertically through probe through hole 101 at the bottom of each battery accommodating groove;
when the shell pressure test of the battery on the battery tray 1 is needed, a shell pressure test needle plate 2 (namely a lower needle plate) which is horizontally distributed is arranged right below the battery tray 1;
a plurality of shell pressure test probes 201 are arranged on the top of the shell pressure test needle plate 2 at positions corresponding to the plurality of probe through holes 101 on the battery tray 1;
the middle parts of the left end and the right end of the shell pressure test needle plate 2, and the middle parts of the front end and the rear end of the shell pressure test needle plate are respectively and fixedly connected with the top telescopic end of a jacking cylinder 3;
and the bottom of the jacking cylinder 3 is arranged on an external equipment platform.
In the present invention, in a specific implementation, the casing pressure test probe 201 on the casing pressure test pin plate 2 is connected to a corresponding detection terminal of an existing OCV (open circuit voltage) test device for a battery.
In the present invention, in a specific implementation, when OCV (open circuit voltage) tests are required for the batteries on the battery tray 1, the open circuit voltage test pin plates 4 (i.e., upper pin plates) are horizontally distributed right above the battery tray 1;
the bottom of the open-circuit voltage test pin plate 4 (i.e., the upper pin plate) is provided with a plurality of open-circuit voltage test probes 401 at positions corresponding to the poles of the batteries in the plurality of battery receiving grooves 102 on the battery tray 1;
the open circuit voltage test pin plate 4 is mounted on the external equipment support above it at the top.
In particular, the open-circuit voltage test probe 401 on the open-circuit voltage test pin plate 4 is connected to a corresponding detection terminal of the existing OCV (open-circuit voltage) test equipment for the battery.
In the present invention, for example, an OCV (open circuit voltage) test tool in a 40ppm device manufactured by sain asia automation equipment (leizhou) ltd may be used as the existing OCV (open circuit voltage) test device for the battery.
It should be noted that, there are two existing test probes in each group, which correspond to a positive and negative pole of a battery, respectively, and a connecting wire is welded to the other end of the probe and connected to two test cables of a test instrument installed in an OCV (open circuit voltage) test device of the battery through an intermediate relay.
It should be noted that the case pressure test is a test of the voltage between the battery negative pole and the battery case.
For the existing battery OCV (open circuit voltage) testing equipment, a testing cable connected with a battery positive pole column is connected in parallel with two intermediate relays connected with the battery positive pole column and a battery shell, and the OCV (open circuit voltage) and shell voltage testing functions are switched through the on-off of the relays.
It should be noted that, in the conventional battery OCV (open circuit voltage) testing device, a mode of performing an OCV (open circuit voltage) and a case voltage test is a testing mode matched with the conventional device, and is not described herein again. The invention specially designs the specific connection structure and the installation position of the related test probe.
Based on the technical scheme, the automatic shell pressure testing tool is suitable for realizing the automatic shell pressure testing after the OCV testing process of the lithium-ion power battery is completed and before the thickness testing process by adding the shell pressure testing function, is added to the OCV testing station, and continues to test the shell pressure after the OCV testing is completed. Wherein, the upper needle plate (open circuit voltage testing needle plate 4) and the OCV testing functional device are shared, and the lower needle plate (shell voltage testing needle plate 2) and the shell voltage testing relay are specially designed. The invention utilizes the hole at the bottom of the battery tray to fix the lower needle plate (the shell pressure test needle plate 2) on the jacking mechanism (namely the jacking cylinder 3) of the original tray, when the jacking mechanism jacks up, the shell pressure test probe upwards passes through the hole (the probe through hole 101) at the bottom of the battery tray to contact the bottom of the battery shell and is matched with the lower pressure of the upper needle plate (the open circuit voltage test needle plate 4) to contact the pole at the top of the battery, and the shell pressure test is finished by the aid of the existing battery OCV (open circuit voltage) test equipment. The invention makes full use of the existing space of the equipment, skillfully combines the shell pressure test function and the OCV test function together, realizes that the same station and the same action complete two test functions, and improves the functional level of the equipment.
In the invention, in the concrete implementation, the holes at the bottom of the battery tray are fully utilized to manufacture the shell pressure test needle plate adaptive to the battery tray, so that each shell pressure test probe can penetrate through the hole at the bottom of the battery tray and directly contact the bottom of the battery, thereby facilitating the collection of the battery shell pressure.
For the invention, the OCV testing station is utilized to realize the shell pressure testing function: in the lithium ion battery separator, the original OCV test mode is as follows: the OCV test needle plate is fixed on the test station, when the whole tray battery flows to the test station, the jacking cylinder jacks up the battery of the whole battery tray at the test station, and at the moment, the polar column of each battery is just contacted with the OCV test probe so as to accurately test related data. The shell pressure test utilizes the original jacking function of this station, places shell pressure test faller in jacking frock on, can make jacking frock decline through proper adjustment jacking frock time, and shell pressure test probe contactless passes through the battery tray of this station. When the jacking cylinder is jacked up, the shell pressure test probe is contacted with the bottom of the battery shell, and the OCV open-circuit voltage test probe is contacted with the pole at the top of the battery, so that the basic condition of battery shell pressure test can be met.
In the invention, in particular, the function switching between the OCV test and the shell voltage test can be realized through the intermediate relay: and the intermediate relays are respectively and serially connected with a power supply loop of the battery OCV (open circuit voltage) testing equipment and a power supply loop of the battery voltage testing equipment.
It should be noted that, when the intermediate relay controls the switching of the two power supply circuits, the connection manner of the upper contacts is a known technique, and is not described herein again.
According to the invention, based on an OCV testing station of the lithium ion battery separator, an intermediate relay is additionally arranged for switching the OCV testing function and the shell pressure testing function, when the OCV is tested, the relay does not act, the relay is attracted and started when the OCV is tested, and the relay is disconnected when the shell pressure testing is finished.
In the invention, the mechanical action control, the test function switching and the data statistics can be further realized by a PLC program and a computer function software program, for example, the action control of the intermediate relay can be realized by the PLC program and is communicated with matched computer function software, the instrument is controlled by the computer function software to realize the test channel switching, the shell pressure test function is better completed, and then the test data is uploaded to an external database for storage by the matched computer function software.
It should be noted that, referring to fig. 1, with the present invention, at the beginning of the battery case pressure test, the case pressure test probe passes through the through hole (i.e. the probe through hole 101) at the bottom of the battery tray and directly contacts the bottom of the battery, so as to collect the case pressure data of the battery.
As shown in fig. 2, the schematic diagram of the casing pressure test needle plate is that the positions of the needle holes of the casing pressure test needle plate correspond to the positions of the through holes at the bottom of the battery tray one by one, so that the casing pressure test probe can smoothly pass through the through holes at the bottom of the battery to contact the bottom of the casing of the battery.
In the concrete implementation, when the shell pressure test needle plate descends, the shell pressure test probe descends below the original conveying chain track, and the conveying chain does not collide with the battery tray when conveying the battery tray; when the case pressure test pin plate is lifted up, the case pressure test probes contact the bottom of the case of the battery through the through holes (i.e., the probe through holes 101) at the bottom of the battery tray.
It should be noted that, for the invention, the shell pressure test function is added on the basis of the lithium ion battery separator, and the shell pressure test function and the OCV test function are combined to form two test functions at the same station, so that the space is reasonably utilized, and the mechanical structure modification cost is saved;
after the invention is applied, the function can be automatically tested on the equipment without adding manpower, so that the manual test and data entry of a staff are needed because the equipment does not have the function, and the labor cost of the procedure is saved. The casing pressure test needle plate is arranged on the OCV jacking plate by fully utilizing the jacking function of the OCV station.
According to the invention, when the conveying chain of the battery tray on the original equipment acts and the jacking cylinder descends, the shell pressure test probe descends below the plane of the conveying chain, and the bottom of the battery tray cannot be contacted with the shell pressure test probe. After the OCV testing mechanism is jacked, the pole columns at the tops of the batteries on the battery tray can contact an OCV testing probe (open-circuit voltage testing probe), the bottom of the batteries can contact a shell pressure testing probe, and two tests of the OCV and the shell pressure can be completed in one jacking process.
For the OCV and shell pressure testing function, the PLC can control the intermediate relay to suck and complete the switching between the two functions.

4. mechanical action control, test function switching and data statistics can be further realized through a PLC program and a computer function software program without the need of additional hardware assistance, so that hardware purchase and processing cost is saved;
5. structural design is reasonable, need not to increase other operations, and two test sequence are accomplished, promote production line functional level, reduce two line body assistants.
