Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, specifically to a lithium battery mold production and testing system. Background Technology

[0002] Lithium batteries are widely used in daily life due to their high energy density and long cycle life, especially in new energy vehicles. In recent years, the development of new energy vehicles has been rapid, so the performance of lithium batteries used in new energy vehicles has also received attention.

[0003] As disclosed in Chinese Patent CN202110659844.7, a high-precision lithium battery electrode production process and system involves placing a current collector into the lower mold of a die-casting device and quantitatively extruding slurry onto the current collector. The upper and lower molds of the die-casting device are heated to a drying temperature. After maintaining the drying temperature for a certain period, the upper and lower molds stop heating, and the current collector is die-cast during the cooling process to obtain the battery electrode. This invention uses a die-casting process instead of the traditional rolling process. After the external force is removed, the current collector will not rebound, and the pressure on all parts of the current collector will be consistent, preventing inconsistent ductility across different areas. Therefore, the thickness and compaction density of the battery electrode produced by the die-casting process can be kept highly consistent, significantly improving the processing quality, precision, and yield of the battery electrode.

[0004] However, in the process of lithium battery mold production, it is necessary to test the performance of the lithium battery mold. The existing testing method may be to manually contact the positive and negative terminals of the lithium battery mold with a sensor pen device in order to detect the quality of the lithium battery mold.

[0005] However, the above method is rather troublesome and cumbersome to operate, and its efficiency is relatively low. Manual operation is subject to certain errors, so there may be missed detections, and the safety performance may be poor. In addition, when testing multiple lithium battery molds, it may be necessary to start and stop the conveyor belt equipment back and forth, which may affect the service life of the conveyor belt equipment and increase production costs. Summary of the Invention

The two arc-shaped covers are located in the deflection area of ​​the lithium battery mold and are in contact with the positive and negative connecting posts. An air outlet is opened on the side of the arc-shaped cover facing the lithium battery mold. Brush bristles are fixedly connected to the side of the arc-shaped cover.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] I. This invention, through the operation of the drive mechanism and the action of the transmission mechanism, first clamps the lithium battery mold laterally and then deflects it. This method provides a stable clamping of the lithium battery mold and facilitates the subsequent contact and alignment of the lithium battery mold with the first and second detection mechanisms. It also improves its stability and avoids situations where the lithium battery mold is unstable. The deflection of the lithium battery mold is coordinated with the lifting, so the lithium battery mold can be aligned with the first detection mechanism on the one hand, and has a rotation cleaning process on the other hand, thus having excellent self-cleaning effect.

[0030] Second, this invention, through the operation of the drive mechanism and the action of the linkage mechanism, lifts the clamped lithium battery mold. Because the lithium battery mold is moved upward, it can be moved away from the conveyor belt equipment. Therefore, the conveyor belt equipment does not need to be stopped when the system is inspecting a single lithium battery mold. This reduces the impact on the service life and maintenance caused by the repeated starting and stopping of the motor in the conveyor belt equipment. This method can lift the lithium battery mold to a certain extent during the clamping and locking process, thus reducing external interference factors and achieving the effect of non-stop conveying. Therefore, it has better practicality and intelligence.

[0031] III. This invention, through the operation of the driving mechanism and under the action of the connecting mechanism, cleans the lithium battery mold, and in conjunction with the deflection form of the transmission mechanism, provides the following:

[0032] First: This method prioritizes the use of air jets, which can clean the surface of the lithium battery mold and the positive and negative terminals with air jets. At the same time, it can also remove dust from the brush bristles with air jets, so as to have a certain self-cleaning effect, making the positive and negative terminals clean, so as to ensure the subsequent automated testing operations.

[0033] Second: Because the movement of the lithium battery mold is in the form of upward movement and rotation, during its rotation, the lithium battery mold and the brush bristles form a relative movement trend, which enables the brush bristles to clean the lithium battery mold in a moving manner, thereby quickly cleaning the dust and impurities on it, so as to ensure the cleanliness of the positive and negative terminals.

[0034] Third: The overall operation has excellent intelligence and linkage. During the clamping, lifting and rotating of the lithium battery mold, the lithium battery mold is pre-processed immediately, which can ensure the normal progress of the test and improve the efficiency of the test, making it more practical.

[0035] Fourth, this invention enables the overall performance testing of the lithium battery mold through the action of testing mechanism one, and the individual lithium battery cells within the lithium battery mold through the action of testing mechanism two. The performance of the lithium battery mold can be determined by observing the illumination of the testing lights on the testing equipment, thus achieving the goal of rapid performance testing of the lithium battery mold. Furthermore, the entire process is mechanized, resulting in a higher level of intelligence. It can also perform individual testing and diagnosis of internal lithium battery cells in problematic lithium battery molds, enabling timely identification and detection, greatly improving work efficiency, and achieving the goal of efficient production testing of lithium battery molds.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] Please see Figures 1 to 8 This embodiment provides a technical solution: a lithium battery mold production and testing system, including: a base 1, a conveyor belt device 2, a lithium battery mold 3, positive and negative connecting columns 4, a support plate 5, a mounting cover 6, a drive mechanism, a transmission mechanism, a linkage mechanism, and a connecting mechanism.

[0048] More specifically, in this embodiment: In actual use, multiple lithium battery pack molds to be tested are placed on conveyor belt devices 2 for transport, with each conveyor belt device 2 spaced a certain distance apart. When the lithium battery mold 3 is in the appropriate position on the conveyor belt, it is detected by sensing, such as by a camera or infrared sensor. At this time, the control board will operate the drive mechanism, which will drive the transmission mechanism and linkage mechanism to operate, thereby clamping and lifting the lithium battery mold 3. After clamping, it will rotate 90°. Therefore, it has the effect of improving detection stability and keeping the lithium battery mold 3 away from the conveyor belt devices 2. It also has the effect of pre-processing the parts of the lithium battery mold 3 to be tested. Then, it can also make the lithium battery mold 3 to be tested face the detection mechanism. Therefore, this system has excellent linkage and intelligence, thus improving the overall detection effect and efficiency.

[0049] It is worth noting that this embodiment also includes: testing institution one and testing institution two.

[0050] More specifically, in this embodiment: after the lithium battery mold 3 has deflected, the control board will drive the first detection mechanism to operate. The first detection mechanism will contact and dock with the positive and negative connecting posts 4 on the lithium battery mold 3, so as to determine whether a single lithium battery mold 3 is in a normal state by means of detection lights. When it is in a normal state, the above mechanism will be reset and then the subsequent lithium battery molds 3 will be detected. When it is in an abnormal state, the control board will drive the second detection mechanism. The second detection mechanism will contact and detect multiple lithium battery units in the lithium battery mold 3 one by one, so as to intelligently detect which specific lithium battery unit has a problem, so as to achieve the purpose of rapid detection.

[0051] Example 2:

[0052] Based on the above embodiments:

[0053] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The driving mechanism in Embodiment 1 is disclosed as follows: The driving mechanism includes:

[0054] Motor 7, the outer shell of motor 7 is fixedly connected to the upper surface of mounting cover 6 via bracket 1, a rotating rod 8 is fixedly connected to the rotating part of motor 7, a rotating plate 9 is fixedly connected to the end of the rotating rod 8, a fixing plate 10 is fixedly connected to the inner wall of mounting cover 6, and an opening 1 is provided in the center of fixing plate 10 for the rotating rod 8 to pass through and to be rotatably connected to it on a fixed axis.

[0055] More specifically, in this embodiment: the control board will operate the motor 7, the rotating part of the motor 7 will drive the rotating rod 8 to rotate, thereby causing the rotating plate 9 to rotate.

[0056] Example 3:

[0057] Based on the above embodiments:

[0058] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The transmission mechanism in Embodiment 1 is disclosed as follows: The transmission mechanism includes:

[0059] Two sliding columns 11 are provided. The lower surface of the fixed plate 10 has two horizontal grooves 12 and one annular groove 13. The annular groove 13 is connected to the horizontal groove 12. The lower surface of the rotating plate 9 has two arc-shaped grooves 14. The sliding columns 11 are slidably connected to the horizontal groove 12, the annular groove 13 and the arc-shaped groove 14. The end of the sliding column 11 is threaded with a screw 15. The end of the screw 15 is fixedly connected with a telescopic pressure plate 16. A spring is fixedly connected inside the telescopic pressure plate 16.

[0060] More specifically, in this embodiment: during use, due to the rotation of the rotating plate 9, and the sliding relationship between the sliding column 11 and the transverse groove 12, the annular groove 13, and the arc-shaped groove 14, as... Figure 4 and Figure 5As shown, under the guidance of the arc surface of the arc groove 14 and the clockwise rotation of the rotating plate 9, the two sliding pillars 11 will move in the transverse groove 12, so that the two sliding pillars 11 will move closer to each other. When they move to the end of the arc groove 14, they will also enter the annular groove 13 from the transverse groove 12. At this time, the continued rotation of the rotating plate 9 will drive the two sliding pillars 11 to rotate synchronously. Therefore, on the lithium battery mold 3, the lithium battery mold 3 is clamped in a limited way, and the telescopic pressure plate 16 is retracted, thereby increasing the clamping force on the lithium battery mold 3. Then, the lithium battery mold 3 is driven to rotate. The actual rotation angle is 90°. When it is necessary to reset, the drive mechanism only needs to be reversed. When the sliding pillar 11 is directly opposite the transverse groove 12, the elastic action of the spring can make the sliding pillar 11 spring into the transverse groove 12 to achieve the effect of quick reset.

[0061] This method helps to ensure that the lithium battery mold 3 is properly aligned with the first and second detection mechanisms, and also improves its stability, preventing instability of the lithium battery mold 3. The deflection of the lithium battery mold 3 is coordinated with the lifting, so that the lithium battery mold 3 can be properly aligned with the first detection mechanism on the one hand, and also has a rotation cleaning process on the other hand, thus having excellent self-cleaning effect.

[0062] Example 4:

[0063] Based on the above embodiments:

[0064] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The linkage mechanism in Embodiment 1 is disclosed as follows: The linkage mechanism includes:

[0065] Two connecting plates 17 are provided. The outer surface of the connecting plate 17 has an opening for the screw 15 to pass through and be fixedly connected thereto. The end of the connecting plate 17 is slidably connected to the slide rod 18. The outer surface of the rotating plate 9 has two guide grooves 36. The groove wall of the guide groove 36 is slidably connected to the end of the slide rod 18. The outer surface of the slide column 11 is fixedly connected to the friction ring 19. The lower surface of the rotating plate 9 is fixedly connected to the arc-shaped friction element 20.

[0066] More specifically, in this embodiment: during use, due to the sliding restriction relationship between the sliding column 11 and the arc groove 14 and the transverse groove 12, the sliding column 11 will slide in the arc groove 14 in the early stage, thereby forming a relative movement trend between the two, so that the friction ring 19 contacts the arc friction element 20, and finally the friction ring 19 and the sliding column 11 rotate. Due to the threaded transmission relationship between the sliding column 11 and the screw 15, and the position restriction of the screw 15 by the connecting plate 17, the screw 15 will not rotate. Therefore, as the sliding column 11 rotates, its internal thread groove rotates, thereby driving the screw 15 to move upward. Through the restriction and adaptation of the sliding rod 18, the telescopic pressure plate 16 can finally drive the lithium battery mold 3 to move upward.

[0067] Because the lithium battery mold 3 is moved upwards, it can be moved away from the conveyor belt 2. Therefore, the conveyor belt 2 does not need to be stopped when the system tests a single lithium battery mold 3. This reduces the impact on the service life and maintenance caused by the repeated starting and stopping of the motor inside the conveyor belt 2. If the lithium battery mold 3 is tested directly on the running conveyor belt 2, due to the conveying nature of the conveyor belt 2, even if the lithium battery mold 3 is locked, it may cause a certain amount of wear on the contact surface between the lithium battery mold 3 and the conveyor belt 2, and may also cause instability. Therefore, to avoid this situation, this method can lift the lithium battery mold 3 to a certain extent during the clamping and locking process, thereby reducing external interference factors and achieving the effect of non-stop conveying. Therefore, it has better practicality and intelligence.

[0068] Example 5:

[0069] Based on the above embodiments:

[0070] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The connecting mechanism in Embodiment 1 is disclosed as follows: The connecting mechanism includes:

[0071] A cam 21 is fixedly connected to the outer surface of the rotating rod 8. A piston mechanism 22 is fixedly connected to the outer surface of the mounting cover 6. The piston mechanism 22 includes a piston cylinder, a piston rod, a piston head, a pressure plate, a spring, an input pipe 23, and two output pipes 24. Both the input pipe 23 and the output pipe 24 are equipped with one-way valves. The end of the output pipe 24 is fixedly connected to an arc-shaped cover 25. The two arc-shaped covers 25 are located in the deflection area of ​​the lithium battery mold 3 and are in contact with the positive and negative connecting posts 4. An air outlet is opened on the side of the arc-shaped cover 25 facing the lithium battery mold 3. Brush bristles 26 are fixedly connected to the side of the arc-shaped cover 25.

[0072] More specifically, in this embodiment: the rotation of the rotating rod 8 drives the cam 21 to rotate, and due to the intermittent contact between the cam 21 and the pressure plate, and the elastic restoring property of the spring 2, the pressure plate, piston rod, and piston head will reciprocate, ultimately causing a change in the pressure inside the piston mechanism 22. This allows clean air from the outside to be drawn into the piston mechanism 22 through the input pipe 23, and then continuously input into the arc-shaped cover 25 through the two output pipes 24. Finally, the gas is sprayed towards the lithium battery mold 3 through the air outlet on it. This method has the following advantages:

[0073] Firstly, in the lithium battery mold 3 production and testing system, the lithium battery mold 3 usually needs to be placed on the conveyor belt equipment 2 for continuous conveying or transfer for production and testing. Therefore, during this process, some dust may adhere to it. If the dust adheres to the positive and negative connection posts 4 or the terminals of a single lithium battery, it may affect the normal connection of the testing equipment, resulting in testing failure or malfunction. Therefore, in order to avoid this situation, this method prioritizes the use of air jet cleaning, which can clean the surface of the lithium battery mold 3 and the positive and negative terminals 4 with air jet cleaning, and can also remove dust from the brush bristles 26 with air jet cleaning, so as to have a certain self-cleaning effect, making the positive and negative terminals 4 clean, so as to ensure the subsequent automated testing operation.

[0074] Secondly, since the movement of the lithium battery mold 3 is in the form of upward movement and rotation, during its rotation, the lithium battery mold 3 and the brush bristles 26 form a relative movement trend, which enables the brush bristles 26 to physically clean the lithium battery mold 3, thereby quickly cleaning the dust and impurities on it, so as to ensure the cleanliness of the positive and negative terminals 4.

[0075] Thirdly, the overall operation has excellent intelligence and linkage. During the clamping, lifting and rotating of the lithium battery mold 3, the lithium battery mold 3 is pre-processed, which can ensure the normal progress of the test and improve the efficiency of the test, making it more practical.

[0076] Example 6:

[0077] Based on the above embodiments:

[0078] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The testing organization in Example 1 is disclosed as follows: Testing organization 1 includes:

[0079] Two electric push rods 27 are fixedly connected to the inner wall of the mounting cover 6. The telescopic part of the electric push rod 27 is fixedly connected to the detection device 37, which is used to connect to the positive and negative connecting posts 4.

[0080] More specifically, in this embodiment: after the lithium battery mold 3 is lifted and deflected, the positive and negative connecting posts 4 on the side of the lithium battery mold 3 are directly aligned with the testing device 37. At this time, the control board will promptly operate the telescopic parts of the two electric push rods 27 to operate, ultimately causing the testing device 37 to contact the corresponding positive and negative connecting posts 4. At this time, the testing device 37 operates, causing the testing light on the testing device 37 to light up. This corresponds to the normal state of the lithium battery mold. When the light does not light up, it corresponds to the state that needs repair. This achieves the purpose of rapid performance testing of the lithium battery mold 3, and the whole process is mechanically operated, thus the level of intelligence is better.

[0081] Example 7:

[0082] Based on the above embodiments:

[0083] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 The second testing organization in Example 1 is disclosed as follows: the second testing organization includes:

[0084] Electric push rod 28, the outer shell of electric push rod 28 is fixedly connected to the inner wall of mounting cover 6. The telescopic part of electric push rod 28 is fixedly connected to L-shaped plate 29. The outer surface of L-shaped plate 29 has three openings 3. The opening wall of opening 3 is slidably connected to moving rod 30. One end of moving rod 30 is fixedly connected to detection block 31. Detection block 31 is provided with positive and negative contact posts. Positive and negative contact posts are connected to the positive and negative terminals of a single lithium battery cell in lithium battery mold 3. The outer shell of motor 2 32 is fixedly connected to the side of L-shaped plate 29. The rotating part of motor 2 32 is fixedly connected to rotating shaft 33. The outer surface of rotating shaft 33 is fixedly connected to three protruding plates 34. The other end of moving rod 30 is fixedly connected to moving plate 35. Moving plate 35 and the opposite side of L-shaped plate 29 are both fixedly connected to spring 3.

[0085] More specifically, in this embodiment: when it is necessary to inspect each lithium battery mold 3 individually, the control board will automatically operate the telescopic part of the electric push rod 28. The operation of the telescopic part of the electric push rod 28 will cause the L-shaped plate 29 to move closer to the deflected and raised lithium battery mold 3. Therefore, the three detection blocks 31 will be aligned with the wiring terminals on the corresponding lithium battery units. At this time, the control board will operate the rotating part of the motor 32, which will then drive the rotating shaft 33 and the convex plate 34 to rotate. Thus, under the contact relationship, and when the angles of the three convex plates 34 are not fixed, such as... Figure 7 As shown, moving from left to right will cause the corresponding detection block 31 to move downwards. Eventually, the downward-moving detection block 31 will come into contact with the positive and negative electrodes of the corresponding lithium battery cell. If the detection block 31 is working normally, the light will illuminate to indicate that it is normal. If the light does not illuminate, it can detect the damage of a specific individual lithium battery cell in a timely manner, thereby achieving the function of timely identification and detection, greatly improving work efficiency, and achieving the purpose of efficient production testing of lithium battery mold 3.

[0086] Working principle: The lithium battery mold production and testing system has the following steps when in use:

[0087] S1: The user first places the lithium battery mold 3 to be tested at intervals on the conveyor belt device 2 and starts the conveyor belt device 2 to transport it. When the lithium battery mold 3 is transported to the area to be tested, intelligent operation is performed through sensing, so that the control board controls the drive mechanism to operate.

[0088] S2: After the drive mechanism is operated, it will drive the transmission mechanism and linkage mechanism to operate, thereby moving the lithium battery mold 3 upward with the variable clamping edge. After the clamping and movement are completed, it will drive the lithium battery mold 3 to deflect, so that the positive and negative connecting columns 4 are directly opposite the detection mechanism.

[0089] S3: The control board will immediately drive the detection mechanism 1 to contact the positive and negative connecting post 4, and then detect and judge the normality of a single lithium battery mold 3 by the lighting status of the detection light. When a single lithium battery mold 3 is abnormal, the control board will immediately manipulate the detection mechanism 2 to move, and make the detection mechanism 2 perform performance tests on multiple lithium battery units in the lithium battery mold 3 one by one, so as to achieve automated detection and judgment.

[0090] S4: After the inspection is completed, the control board will randomly download the information corresponding to the lithium battery mold 3, and then drive the drive mechanism to reverse, so that the lithium battery mold 3 is rotated, lowered and released, so that it can re-enter the conveyor belt equipment 2 for transportation.

[0091] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
