Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production equipment, in particular to an OCV test motion mechanism. BACKGROUND

[0002] The battery module OCV refers to the open-circuit voltage of the battery, which is also the positive and negative electrode voltage difference when the battery is not open circuit. In order to improve the detection efficiency, the enterprise needs to detect the OCV of the battery module at the same time when detecting the voltage resistance of the battery module. The detection device in the prior art usually adopts the detection mode of detecting one by one when detecting the battery module, or detects the battery cell one by one manually, so that the detection efficiency is low. Similarly, the conventional OCV detection considers the number of tests at one time, adopts single-channel multiple switching test, frequently uses relays to switch, the circuit is complicated, frequent switching is easy to cause interference, and the overall time is relatively long.

[0003] In the prior art, a battery OCV tester and a test assembly are disclosed in Chinese Patent No. CN210730226U, which comprises a frame placing plate, a bottom plate, an OCV test mechanism and a jacking cylinder. The test mechanism is installed on the bottom plate, and the jacking cylinder is installed on the bottom plate and located on one side of the test mechanism. The cylinder rod of the jacking cylinder is vertically upward and connected with the frame placing plate. The frame placing plate is located above the test mechanism. The frame placing plate is set as a hollow structure, the bottom of the frame is set as a hollow structure, the battery is placed inside the frame, the tab of the battery is set downward and extends out of the frame and is tested by the test mechanism. However, the above-mentioned battery OCV tester still has the problems of low automation and intelligence, low detection efficiency, and the like. Moreover, in actual production, since the thickness of each battery in the user tray may not be consistent, it is difficult for the probe (temperature probe, shell probe) assembly to be compatible and crimped to the battery poles on both sides during the OCV test process, resulting in poor adaptability of the existing OCV test probe module. Therefore, the probe module needs to be frequently replaced according to different types of batteries, which greatly reduces the work efficiency. Therefore, improvement is needed. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an OCV test motion mechanism, which has high automation and intelligence, can realize automatic conveying, positioning and OCV detection of the battery restraint tray loaded with multiple blade batteries, and greatly improves the detection efficiency.

[0005] To achieve the above technical solutions, the application provides an OCV test moving mechanism, which comprises a bottom plate, two parallel and spaced supports installed on the bottom plate along an X direction, a test control plate installed between the top portions of the two supports, a conveying line guide base installed at the bottom of the test control plate, a plurality of parallel and spaced conveying rollers installed on the conveying line guide base along the X direction, a synchronous belt connecting the conveying rollers, a roller driving motor installed on the conveying line guide base and connected with one of the conveying rollers, a battery restraining tray placed on the conveying roller, a positioning jacking cylinder vertically upwardly installed at the bottom of the bottom plate along a Z direction, a rear blocking block installed at the rear end of the conveying line guide base, an in-place micro switch installed on the rear blocking block, a code scanning gun installed at the rear end of the conveying line guide base and facing the battery restraining tray, OCV test probe modules installed on the left and right sides of the conveying line guide base along a Y direction and facing the battery restraining tray, and the two OCV test probe modules being connected with the test control plate through a wire harness.

Because the probe assembly spring is installed between adjacent probe assemblies, the distance between each probe assembly is the same, so the concave guide block on the probe assembly can be guided in under the condition that the thickness of each column of batteries in the tray is the same. Then, the Y-direction push-pull cylinder can push the module mounting frame and the entire probe module together to the position along the Y-direction, so that the probe module is in pressure contact with the battery, and the battery is in test docking with each probe assembly.

In actual work, the module mounting frame 23 and the whole probe module can be pushed to the position along the Y direction by the Y direction push-pull cylinder 27, so that the probe module is in contact with the battery by probe crimping, and the battery is in test docking with each probe assembly 26. When all the batteries are completed crimping and testing, the Y direction push-pull cylinder 27 drives the module mounting frame 23 to exit, and the test function is completed.

[0031] Referring to Figures 4 to 6As shown, the back of the module mounting frame 23 is mounted with a probe module mounting plate 25, two probe assembly X-direction guide rails 213 are mounted on the probe module mounting plate 25 in parallel and spaced apart along the Z direction, a plurality of probe assemblies 26 are mounted on the probe assembly X-direction guide rails 213 in parallel and spaced apart, the back of adjacent probe assemblies 26 is connected by a long hole connecting plate 29, the back of each probe assembly 26 is mounted with a long hole fixing screw 210 which is inserted into the long hole of the long hole connecting plate 29, so that the adjacent probe assemblies 26 can be pushed or pulled, probe assembly springs 217 are mounted between the sides of adjacent probe assemblies 26, the probe assembly springs 217 ensure that the distance between each probe assembly 26 is the same, an electric cylinder pushing block 215 is mounted on the left side end of the first probe assembly 26, a tray liner detection photoelectric sensor 211 is mounted on the electric cylinder pushing block 215 and faces the battery restraining tray along the Y direction, the tray liner detection photoelectric sensor 211 is used to detect the tray liner on the battery restraining tray 3, a probe module push-pull electric cylinder 24 is mounted on the module mounting frame 23 and connected with the electric cylinder pushing block 215, an X-direction adjusting screw 212 is mounted on the right side end of the probe assembly X-direction guide rail 213 and is used to limit the movement position of the rightmost probe assembly 26 and fine adjust the limit position of the last probe assembly 26. In actual work, the tray liner detection photoelectric sensor 211 moves with the electric cylinder pushing block 215 pushed by the probe module push-pull electric cylinder 24, when the tray liner detection photoelectric sensor 211 detects the tray liner on the battery restraining tray 3, the probe module push-pull electric cylinder 24 stops pushing, because the probe assembly springs 217 are mounted between adjacent probe assemblies 26, the distance between each probe assembly 26 is the same, so that the concave guide block 267 on the probe assembly 26 can be guided in only when the thickness of each column of batteries on the tray is the same.

[0032] Referring to Figure 7As shown, the probe assembly 26 comprises a probe mounting rack 261, the top and bottom of which are mounted with slide mounting plates 262, the back of which is mounted with slide blocks 263, the probe mounting rack 261 is embeddedly mounted on the probe assembly X guide rail 213 provided on the probe module mounting plate 25 through the slide blocks 263, the top of the probe mounting rack 261 is mounted with a guide block mounting seat 265, a concave guide block 267 is mounted at the front end of the guide block mounting seat 265, and a compression spring 266 is mounted between the concave guide block 267 and the guide block mounting seat 265, the front side of the probe mounting rack 261 is mounted with a shell probe 268, the lower side of the shell probe 268 is mounted with a temperature probe 269, and the lower side of the temperature probe 269 is mounted with two parallel and spaced apart pole column probes 2610. In actual work, the function of the concave guide block 267 is to realize the insertion positioning of each probe assembly 26, and the shell probe 268, the temperature probe 269 and the pole column probe 2610 are respectively used for interfacing with the shell, the battery cell and the pole column on the battery. The top of the probe mounting rack 261 of the last probe assembly 26 is mounted with a concave guide block detection photoelectric sensor 216 arranged opposite to the concave guide block 267 along the X direction, so as to detect whether each concave guide block 267 is inserted in place in the actual test process. A plurality of spring mounting holes 264 are provided on the left side and the right side of the probe mounting rack 261, one end of the probe assembly spring 217 is inserted and mounted in the spring mounting hole 264, and in actual work, the function of the probe assembly spring 217 is to ensure that the distance between each probe assembly 26 is the same. In actual work, the pushing of the whole row of probe assemblies 26 is realized by the double-stroke Y-direction push-pull cylinder 27 to realize the guiding and crimping functions: in the first stage, the probe module guiding function is pushed, if the concave guide block 267 is not guided into the tray lining block convex guide block of the battery restraining tray 3, the concave guide block 267 will move backward under the action of the compression spring 266, and the photoelectric sensor will be triggered, then the Y-direction push-pull cylinder 27 will return to the original position and alarm; in the second stage, the probe module probe crimping function is pushed, the first stage concave guide block 267 is guided into the lining block convex guide block of the battery restraining tray 3, then the first stage Y-direction push-pull cylinder 27 does not trigger the alarm, the second stage Y-direction push-pull cylinder 27 is started, at this time the photoelectric sensor shielding sensing function (if not shielded, the concave guide block will trigger the photoelectric sensor when the probe is crimped to the pole column), and the test function is completed when the pole column probe is crimped to the pole column, so as to further ensure the safety of the probe assembly 26 in the pushing process.

[0033] In order to further explain the present application, the overall operation process of the present application is explained as follows:

[0034] (1) Loading and positioning: the battery restraint tray 3 loaded with the blade battery is delivered to the conveying drum 8 by the forklift, the drum driving motor 7 drives the conveying drum 8 to convey the battery restraint tray 3 backward to the position, then the positioning lifting cylinder 10 is lifted to fix the position of the battery restraint tray 3, and then the code scanning gun 13 scans the code information on the battery restraint tray, and the two OCV test probe modules 2 are controlled to move inward by the test control panel 4;

[0035] (2) Probe module alignment: the tray liner detection photoelectric sensor 211 moves along with the cylinder pushing block 215 pushed by the probe module push-pull cylinder 24, and when the tray liner detection photoelectric sensor 211 detects the tray liner on the battery restraint tray 3, the probe module push-pull cylinder 24 stops pushing. Since the probe assembly spring 217 is installed between the adjacent probe assemblies 26, the distance between each probe assembly 26 is the same, so that the concave guide block 267 on the probe assembly 26 can be guided in under the condition that the thickness of each column of batteries on the tray is the same;

[0036] (3) Detection: the Y-direction push-pull cylinder 27 pushes the module mounting frame 23 and the entire probe assembly 26 mounted on the module mounting frame 23 to the position along the Y-direction, so that the probe assembly 26 is in contact with the battery, realizing the test connection of the battery and each probe assembly 26. During this period, the pushing of the entire column of probe assemblies 26 is realized by the double-stroke Y-direction push-pull cylinder 27 in two stages to realize the guiding and pressing functions: the first stage is the probe module guiding function. If the concave guide block 267 is not guided into the tray liner convex guide block of the battery restraint tray 3, the concave guide block 267 will move backward under the action of the compression spring 266 and trigger the photoelectric sensing, and then the Y-direction push-pull cylinder 27 will return to the original position and alarm. The second stage is the probe module probe pressing function. If the concave guide block 267 is guided into the liner convex guide block of the battery restraint tray 3 in the first stage, the first stage Y-direction push-pull cylinder 27 does not trigger the alarm, and the second stage Y-direction push-pull cylinder 27 is started. At this time, the photoelectric sensing shielding sensing function is triggered (if not shielded, the concave guide block will trigger the photoelectric sensing when the probe is pressed to the pole), and the test function is completed when the pole probe is pressed to the pole;

[0037] (4) Material withdrawal: when all the batteries are pressed and tested, the Y-direction push-pull cylinder 27 drives the module mounting frame 23 and the entire probe assembly 26 mounted on the module mounting frame 23 to exit, completing the test function, and then the positioning lifting cylinder 10 is reset, and the conveying drum 8 conveys the tested battery restraint tray 3 forward, and the forklift unloads the tested battery restraint tray 3.

[0038] The OCV test mechanism has high automation and intelligence, and can realize automatic conveying, positioning and OCV detection of the battery restraint tray 3 loaded with multiple blade batteries, greatly improving the detection efficiency. Through the structural design of the OCV test probe module 2, in the case that the thickness of each battery in the user tray is inconsistent, the OCV test probe (temperature probe, shell probe) assembly can be compatible and crimped to the battery poles on both sides, without the need to replace different types of probe assemblies, improving the adaptability and working efficiency of the probe module. Through the structural design of the probe assembly 26, through the structure design of the concave guide block 267 and the compression spring 266, not only the accuracy of the probe assembly 26 and the battery crimping can be improved, but also the safety of the probe assembly 26 in the advancing process can be further improved.

[0039] The above is a preferred embodiment of the present application, but the present application should not be limited to the embodiment and the content disclosed in the drawings, so any equivalent or modification made without departing from the spirit of the present application falls within the scope of the present application.
