Description

Technical Field

[0001] The present invention relates to the field of lithium battery formation and grading, and particularly to a valve inserting device. Background Art

[0002] In the current process of lithium battery formation and grading, the batteries that have undergone formation need to be transported along the conveyor line to the station for inserting the battery safety valves, and the safety valves are inserted into the liquid injection holes of the batteries to prevent the electrolyte with a relatively high temperature and active chemical properties in the batteries from volatilizing into the air, resulting in air pollution.

[0003] In the existing process of inserting safety valves, after the valve insertion is completed, the main detection work relies on opposed fiber optic sensors. Since the electrolyte inside the battery is relatively active and easy to volatilize and adhere to the opposed fiber optic sensors, it will not only affect the detection accuracy of the opposed fiber optic sensors, increase the false detection rate, but also corrode the opposed fiber optic sensors and shorten the service life of the opposed fiber optic sensors.

[0004] In the existing battery production process, generally, the batteries that have completed the first activation after undergoing multiple charge and discharge processes are placed in battery trays and transported to different devices in sequence through a transportation device to complete the processes of placing safety valves, inserting valves, and detecting, etc. This not only consumes a lot of time during the transportation process, but also the production equipment occupies a large space, affecting the space utilization rate of the production site. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a valve inserting device, which can effectively increase the space utilization rate of the valve inserting device.

[0007] Further, the moving device includes: a bracket; a lateral moving mechanism arranged on the bracket and capable of sliding relative to the bracket in the left - right direction; a longitudinal moving mechanism arranged on the lateral moving mechanism and capable of sliding relative to the lateral moving mechanism in the front - back direction; a vertical moving mechanism arranged on the lateral moving mechanism and capable of sliding relative to the lateral moving mechanism in the up - down direction; and a connecting plate arranged on the vertical moving mechanism.

[0008] Further, the moving device further includes a driving mechanism arranged on the bracket, and the driving mechanism is used to drive the lateral moving mechanism, and / or the longitudinal moving mechanism and / or the vertical moving mechanism to slide.

[0009] Further, a feeding device is arranged below the mobile device, and the feeding device is used to transport the safety valve to the grasping position.

[0010] Further, a vibrating guide rail is arranged below the mobile device, and the feeding device is used to transport the safety valve output by the vibrating guide rail to the grasping position.

[0011] Further, a vibrating disk is arranged below the mobile device, and the vibrating disk is used to supply the safety valve to the vibrating guide rail.

[0012] Further, a plurality of conveying rollers are arranged below the mobile device, and the conveying rollers are used to transport the battery tray.

[0013] Further, a lifting device is arranged below the mobile device, and the lifting device is used to lift the battery tray transported by the conveying rollers.

[0014] Further, a limiting device is arranged above the lifting device. When the lifting device lifts the battery tray, the limiting device can limit the battery in the battery tray.

[0015] Further, the lifting device includes a plurality of cylinders and a lifting bracket arranged below the mobile device. The plurality of cylinders are all drivingly connected to the lifting bracket; the lifting bracket is used to lift the battery tray.

[0016] When the plug valve device of the present invention is used, the battery can be placed below the mobile device, and then the mobile device is used to move the grasping device, the pressing device, and the plug valve detection device to above the battery in sequence, and processes such as placing the safety valve, pressing the valve, and plug valve detection are performed on the battery in sequence; since the corresponding devices are all integrated on the mobile device, there is no need to move the battery during the three processes, and only the mobile device needs to be controlled to move different devices, effectively saving the time required to move the battery and the occupied space of the device for moving the battery.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0036] In the description of the present invention, the meaning of "several" is one or more, the meaning of "multiple" is more than two, and understandings such as "greater than", "less than", "exceeding", etc. do not include the corresponding number, and understandings such as "above", "below", "within", etc. include the corresponding number. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0038] Refer to Figures 1 - 3 , a feeding device 100 according to the first aspect of this embodiment includes: a base 110; a carrier plate 140 provided on the base 110, and the carrier plate 140 is provided with a positioning hole through which a safety valve can pass in the up-and-down direction; a first push block 132 provided above the carrier plate 140 and movably connected to the carrier plate 140; the first push block 132 is provided with an abutting portion that can abut against the safety valve and push the safety valve above the positioning hole; a conveying block 150 provided below the carrier plate 140 and slidably connected to the base 110, and the conveying block 150 is used to carry the safety valve falling from the positioning hole.

[0039] When the feeding device 100 of this embodiment is applied, during use, the safety valve can be conveyed to the carrier plate 140 through the vibration guide rail 122, so that the safety valve moves above the positioning hole, and then the safety valve falls along the positioning hole onto the conveying block 150, and the conveying block 150 transports the safety valve to the grasping position for the grasping device 300 to grasp; since the safety valve is positioned by the positioning hole during the process of falling onto the conveying block 150, the position accuracy of the safety valve on the conveying block 150 can be ensured; at the same time, the safety valve falling onto the conveying block 150 has no vibration relative to the conveying block 150, which is convenient for the grasping device 300 to accurately position the safety valve.

[0040] Among them, the safety valve can slide into the positioning hole on the carrier plate 140 in various ways. For example, the carrier plate 140 is inclined so that the safety valve naturally slides into the positioning hole under the action of gravity; or the output end of the external vibration guide rail 122 is directly aligned with the positioning hole, so that the safety valve can fall into the positioning hole after sliding out of the vibration guide rail 122; or the safety valve can be pushed from the carrier plate 140 above the positioning hole through a ground connection component so that the safety valve can fall into the positioning hole.

[0041] It can be understood that the conveying block 150 can also slide relative to the base 110 in various ways to convey the safety valve to the grasping position. For example, it can be driven by a driving component such as a cylinder or a hydraulic cylinder to drive the conveying block 150 to slide, or manually driven to drive the conveying block 150 to slide.

[0042] As Figure 2 , Figure 3 shown, a first pushing block 132 is arranged above the bearing plate 140. The first pushing block 132 is movably connected to the bearing plate 140, and an abutting portion capable of abutting against the safety valve and pushing the safety valve above the positioning hole is arranged on the first pushing block 132; during feeding, the external vibrating guide rail 122 can convey the safety valve to abut against the abutting portion, and then the first pushing block 132 pushes the safety valve above the positioning hole, so that the safety valve falls into the positioning hole. When feeding is not required for a short time, the output end of the vibrating guide rail 122 can be blocked by the first pushing block. At this time, the safety valve on the vibrating guide rail 122 will not slide out of the vibrating guide rail 122, and there is no need to stop the vibration of the vibrating guide rail 122.

[0043] Similarly, the first pushing block 132 can push the safety valve above the positioning hole in various ways. For example, the first pushing block 132 is pushed by a cylinder or a hydraulic cylinder, so that the first pushing block 132 slides relative to the bearing plate 140; or by means of a motor or a hydraulic motor, etc., the first pushing block 132 is driven to rotate relative to the bearing plate 140 to push the safety valve above the positioning hole.

[0044] Specifically, as Figure 2 shown, the abutting portion can be a depression arranged on the first pushing block 132 and having a shape matching that of the safety valve.

[0045] Furthermore, as Figure 2 shown, a valve pressing device 141 is arranged above the bearing plate 140. The valve pressing device 141 can press down relative to the bearing plate 140 and press the safety valve into the positioning hole; when the safety valve moves above the positioning hole, it is easy to shift relative to the positioning hole and cause jamming. At this time, by arranging the valve pressing device 141, the safety valve can be made to slide out of the positioning hole downward; it can be understood that the valve pressing device 141 can press down the safety valve in various ways. For example, a cylinder or a motor arranged above the positioning hole is used to push the piston to press down and press the safety valve out of the positioning hole, or an electromagnet arranged below the positioning hole is used to suck the safety valve downward out of the positioning hole; as long as a force can be applied to the safety valve so that the safety valve can slide out of the positioning hole downward.

[0046] As Figure 2As shown, a receiving portion 151 is provided on the conveying block 150. The receiving portion 151 is used to receive the safety valve that falls from the positioning hole. The receiving portion 151 can ensure the stability of the relative position of the safety valve on the conveying block 150, so that the safety valve can be accurately transported to the grasping position under the transportation of the conveying block 150.

[0047] As Figure 2 shown, a first air cylinder 131 is provided on the bearing plate 140, and the first pushing block 132 can slide back and forth under the drive of the first air cylinder 131.

[0048] Furthermore, a second air cylinder 160 is provided on the base 110, and the second air cylinder 160 can drive the conveying block 150 to slide back and forth.

[0049] As Figure 2 shown, a photoelectric inductor is provided on one side in the sliding direction of the conveying block 150. When the safety valve gets stuck in the positioning hole, the photoelectric inductor can sense that there is no safety valve on the conveying block 150. At this time, the feeding device 100 can be controlled to stop working, and the on-site staff can be notified to come and handle it. Preferably, a through-beam fiber optic can be used as the photoelectric inductor.

[0050] For the purpose of protecting the cables connected to the conveying block 150, a drag chain connected to the conveying block 150 is also provided on the base 110.

[0051] In the second aspect of this embodiment, a feeding system is further provided, including the above-mentioned feeding device 100, and may further include a conveying device for supplying safety valves to the feeding device 100. Among them, the conveying device can be a vibrating guide rail 122, or a belt conveyor or a conveying roller for transporting safety valves, etc.

[0052] Among them, in order to facilitate taking materials from the vibrating disk 121, a vibrating guide rail 122 is provided on the base 110, and the discharging end of the vibrating guide rail 122 is opposite to the position of the abutting portion.

[0053] As Figures 3 - 5 shown, the grasping device 300 in the third aspect of this embodiment is characterized by including: a connecting plate 200 for docking with the moving device 600; a lifting driving device provided on the connecting plate 200; and a grasping mechanism drivingly connected to the lifting driving device, and the grasping mechanism is used to grasp the safety valve.

[0054] When the grasping device 300 of this embodiment is applied, during use, the connecting plate 200 can be driven so that the grasping device 300 is located below the battery filling hole, and then the lifting driving device is controlled to descend, so that the safety valve on the grasping mechanism falls above the battery filling hole. Since only the lifting driving device needs to drive the grasping mechanism during the whole process, and there is no need to drive the connecting plate 200 to descend, it effectively reduces the interference of other devices on the connecting plate 200 with the battery during the grasping process.

[0055] As Figure 4 , Figure 5 shown, in this embodiment, a grasping device 300, a pressing device 400, and an inserting valve detection device 500 are integrated on the connecting plate 200. For example, by lifting and lowering the connecting plate 200 to make the grasping device 300 lift and lower, it is easy to cause the pressing device 400 and the inserting valve detection device 500 to collide with the battery.

[0056] Among them, the lifting drive device can drive the grasping mechanism to lift and lower in various ways. For example, a cylinder or a hydraulic cylinder provided on the connecting plate 200 can drive the grasping mechanism to lift and lower, or a linear motor or a motor gear rack mechanism can also drive the grasping mechanism to lift and lower.

[0057] It should be understood that the grasping device 300 can also grasp the safety valve in various ways. For example, a pneumatic gripper driven and connected to the lifting drive device can clamp the safety valve, or the safety valve can be sucked by a vacuum chuck 330 or a vacuum nozzle and other devices, or the safety valve can be attracted by an electromagnet driven and connected to the lifting drive device.

[0058] Furthermore, as Figure 6 shown, the lifting drive device includes a grasping cylinder 310 provided on the connecting plate 200. The grasping cylinder 310 is drivingly connected to a grasping rod 320, and the lower end of the grasping rod 320 is connected to a grasping mechanism; among them, the use of the grasping rod 320 can ensure that the grasped safety valve will not collide with the pressing device 400.

[0059] As Figure 6 shown, the grasping device 300 includes a vacuum chuck 330 provided at the lower end of the grasping rod 320.

[0060] Furthermore, in order to facilitate vacuum pumping of the vacuum chuck 330 and reduce the exposed pipelines outside, an exhaust passage is provided through the inside of the grasping rod 320, and the exhaust passage is communicated with the vacuum chuck 330; as Figure 6 shown, the vacuum pumping device can be directly connected above the grasping rod 320 to reduce the difficulty of pipeline routing caused by routing pipes below the grasping rod 320.

[0061] In order to enable the grasping rod 320 to slide up and down stably relative to the connecting plate 200, a linear bearing is provided on the connecting plate 200, and the grasping rod 320 is slidably connected to the connecting plate 200 through the linear bearing.

[0062] Among them, a buffer 312 can be provided between the grasping rod 320 and the connecting plate 200 to reduce the impact on the connecting plate 200 during grasping, and the buffer 312 is preferably a compression spring.

[0063] As Figure 4As shown, two grasping rods 320 are arranged on the connecting plate 200 in the front-rear direction, and a grasping mechanism is connected below each grasping rod 320; at this time, the two grasping mechanisms can be controlled to grasp a safety valve respectively, and place the safety valves on two batteries simultaneously.

[0064] Furthermore, in order to independently control the two grasping rods 320, two lifting drive devices are arranged on the connecting plate 200, and the two lifting drive devices are respectively connected to the two grasping rods 320 in a one-to-one correspondence.

[0065] Refer to Figures 4 - 6 , the pressing device 400 of the fourth aspect of this embodiment includes: a connecting plate 200 for docking with the moving device 600; a fixed sleeve 420 connected to the connecting plate 200, the fixed sleeve 420 having a first inner cavity communicating with an external air extraction device; a sliding sleeve 450 located in the first inner cavity and slidably connected to the fixed sleeve 420, the sliding sleeve 450 having a second inner cavity communicating with the first inner cavity, and the second inner cavity being able to communicate with the safety valve; a valve pressing rod 460 partially located in the second inner cavity and connected to the connecting plate 200.

[0066] When applying the pressing device 400 of this embodiment, during use, the connecting plate 200 can be controlled to descend, so that the sliding sleeve 450 wraps the safety valve and the lower end of the sliding sleeve 450 abuts against the battery, and then the external air extraction device is controlled to extract the gas in the first inner cavity, so that the volatilized gas of the electrolyte inside the battery is sequentially passed through the second inner cavity and the first inner cavity and then extracted. After that, the connecting plate 200 is directly controlled to continue descending, so that the valve pressing rod 460 in the second inner cavity presses the safety valve into the liquid injection hole. The entire pressing process first extracts gas and then presses the valve, effectively reducing the situation of the battery bulging due to the volatilization of the electrolyte. At the same time, the valve pressing process is carried out in a vacuum environment, effectively reducing the possibility of air entering the battery interior.

[0067] Specifically, after evacuating the inside of the battery, without evacuating the sliding sleeve 450, the connecting plate 200 is directly controlled to continue descending. At this time, the sliding sleeve 450 can slide upward relative to the fixed sleeve 420, and the tab valve pressing rod 460 descends to abut against the safety valve and presses the safety valve into the battery liquid injection hole. During this process, the sliding sleeve 450 always abuts against the battery, which can effectively reduce the possibility of external air entering the battery liquid injection hole; at the same time, only the connecting plate 200 needs to be controlled to descend during the whole process, without translation, effectively simplifying the control of the equipment.

[0068] Furthermore, as Figure 6As shown, in order to ensure that when the sliding sleeve 450 slides relative to the fixed sleeve 420, external air does not penetrate along the gap between the sliding sleeve 450 and the fixed sleeve 420, and to ensure the vacuum degree of the first inner cavity and the second inner cavity, a sealing ring 452 is provided on the sliding sleeve 450. The sealing ring 452 is used to block the gap between the sliding sleeve 450 and the fixed sleeve 420; as Figure 6 shown, a flange is provided at the upper end of the sliding sleeve 450. The sealing ring 452 is sleeved around the flange, and the sealing ring 452 abuts against both the flange and the inner wall of the fixed sleeve 420 at the same time, so that air does not penetrate from the gap between the sliding sleeve 450 and the fixed sleeve 420.

[0069] As Figure 6 shown, in order to further prevent air from penetrating from the gap between the sliding sleeve 450 and the battery, a sealing ring 451 can be provided at the lower end of the sliding sleeve 450. When the lower end of the sliding sleeve 450 abuts against the battery, the sealing ring 451 can block the gap between the sliding sleeve 450 and the battery, ensuring the effect of vacuum pumping.

[0070] Furthermore, a connecting block 410 is provided on the connecting plate 200. Both the fixed sleeve 420 and the pressure valve rod 460 are provided on the connecting block 410.

[0071] As Figure 4 、 Figure 6 shown, in order to facilitate connecting the first inner cavity to an external air extraction device and facilitating vacuum pumping of the first inner cavity and the second inner cavity, a pipe connection part 401 is provided on the connecting block 410. The pipe connection part 401 is communicated with the first inner cavity; at this time, only the pipeline of the vacuum extraction device needs to be connected to the pipe connection part 401, and then the vacuum pumping operation can be carried out on the first inner cavity and the second inner cavity.

[0072] As Figure 6 shown, in order to further prevent air leakage between the sliding sleeve 450 and the fixed sleeve 420 while facilitating the assembly of the sliding sleeve 450 and the fixed sleeve 420 together, a sealing cover 440 is provided at the lower end of the fixed sleeve 420. The sealing cover 440 is in sliding fit with the sliding sleeve 450, and the sealing cover 440 is detachably connected to the fixed sleeve 420; during assembly, the sliding sleeve 450 can be first inserted into the first inner cavity, then the sealing cover 440 is sleeved around the sliding sleeve 450, and finally the sealing cover 440 is installed at the lower end of the fixed sleeve 420; the sealing cover 440 can be detachably connected to the fixed sleeve 420 in various ways such as by snap fasteners, threaded fasteners, etc.

[0073] As Figure 6As shown, a compression spring 430 is sleeved around the pressure valve rod 460. The two ends of the compression spring 430 are respectively connected to the connecting plate 200 and the sliding sleeve 450. When the sliding sleeve 450 abuts against the battery, the compression spring 430 can buffer the impact generated when the sliding sleeve 450 and the battery collide, preventing the sliding sleeve 450 from being damaged. Further, the compression spring 430 can also ensure that the sliding sleeve 450 is in the extended state usually. When the connecting plate 200 descends, the sliding sleeve 450 abuts against the battery first, and then the pressure valve rod 460 presses the safety valve into the battery liquid injection hole, preventing the safety valve from being inserted into the liquid injection hole without completing the vacuum pumping process, resulting in production accidents.

[0074] As Figure 7 shown, the pressure valve rod 460 has a third inner cavity, and a grasping rod 320 is arranged in the third inner cavity. A vacuum suction cup 330 is arranged at the lower end of the grasping rod 320. During the valve inserting process, the vacuum suction cup 330 can be controlled to suck the safety valve, and then the connecting plate 200 is controlled to make the vacuum suction cup 330 move above the battery and start to descend. First, the safety valve is placed above the liquid injection hole, and then when the sliding sleeve 450 abuts against the battery, the external air extraction device can be controlled to evacuate the first inner cavity, and then the connecting plate 200 is controlled to continue to descend, so that the pressure valve rod 460 presses the safety valve into the battery liquid injection hole to complete the valve inserting work. The whole process of placing the safety valve and inserting the valve only requires the connecting plate 200 to descend, without translation, effectively saving production time.

[0075] Further, an exhaust passage is arranged through the grasping rod 320, and the exhaust passage is communicated with the vacuum suction cup 330. At this time, the vacuum suction cup 330 can be provided with vacuum suction force by directly evacuating the other end of the grasping rod 320 away from the vacuum suction cup 330, which is convenient for grasping.

[0076] Specifically, as Figure 7 shown, a base 110 is arranged on the connecting plate 200. The fixed sleeve 420, the pressure valve rod 460 and the grasping rod 320 are all arranged on the base 110. A connecting pipe part communicated with the exhaust passage is arranged on the base 110. At this time, the external air extraction device can be connected to the connecting pipe part to provide suction force for the vacuum suction cup 330, further facilitating the layout of the pipeline.

[0077] As Figure 6 shown, the valve inserting detection device 500 of the fifth aspect of this embodiment includes: a connecting plate 200 for docking with the moving device 600; a detection rod 520 capable of sliding up and down relative to the connecting plate 200; and an induction device for detecting the displacement of the detection rod 520 relative to the induction device in the up and down direction.

[0078] When the plug valve detection device 500 of this embodiment is applied, after the plug valve is completed, the connecting plate 200 can be driven to move the detection rod 520 above the detection position, and then the induction device and the detection rod 520 are controlled to descend a specified distance. When the induction device senses that the detection rod 520 generates a displacement in the up and down direction relative to the detection position, it can be determined that the safety valve is accurately inserted into the liquid injection hole; the detection is completed entirely by mechanical components without using opposed fiber optics, which can effectively reduce the impact of the volatile electrolyte on the detection equipment and improve the accuracy and service life of the detection equipment.

[0079] Among them, the induction device can sense the displacement of the detection rod 520 relative to the induction device in various ways. For example, a contact switch is set on the connecting plate 200. When the detection rod 520 is impacted during the descending process, the contact switch can be triggered, and the displacement of the detection rod 520 relative to the connecting plate 200 can be detected; a magnetic ring can also be set on the detection rod 520, and a sensor 532 is set on the connecting plate 200, and the displacement of the magnetic ring is measured by the sensor 532, etc.

[0080] It can be understood that the above-mentioned specified distance can be flexibly determined according to the battery size and the device size. As long as the detection rod 520 can touch the safety valve when the battery is normally inserted into the safety valve; and when the battery is not correctly inserted into the safety valve, the detection rod 520 cannot touch the safety valve after descending the specified distance, and the induction device does not sense the displacement of the detection rod 520. At this time, it can be determined that the plug valve fails.

[0081] It should be understood that the process of driving the detection rod 520 and the induction device to descend can be completed either by the moving device 600 driving the connecting plate 200 to descend or by the lifting drive device provided on the connecting plate 200 driving the induction device and the detection rod 520 to descend. Specifically, as Figure 6 shown, a lifting drive device is provided on the connecting plate 200. The lifting drive device is drivingly connected to the induction device, and the detection rod 520 is slidably connected to the induction device. The detection rod 520 can slide up and down relative to the induction device.

[0082] Among them, in order to be able to arrange the lifting drive device and the detection rod 520 non-coaxially, facilitate the arrangement of the position of the lifting drive device, and save the occupied space of the device, the lifting drive device includes a detection cylinder 510 provided on the connecting plate 200. The detection cylinder 510 is drivingly connected to a second connecting rod 511, and the second connecting rod 511 is slidably connected to the detection device.

[0083] Among them, in order to make the up and down sliding of the detection rod 520 relative to the connecting plate 200 smooth, a linear bearing is provided on the connecting plate 200, and the detection rod 520 can be slidably connected to the connecting plate 200 through the linear bearing.

[0084] As shown Figure 6 in the figure, a buffer spring 540 is connected between the detection rod 520 and the detection device; when the detection rod 520 is impacted, the buffer spring 540 can buffer the impact received by the detection rod 520 to prevent the detection device from being greatly impacted and affecting the measurement accuracy; when the connecting plate 200 rises after the detection is completed, the buffer spring 540 can drive the detection rod 520 to automatically return to the initial state, facilitating the next detection.

[0085] Among them, in order to further reduce the impact on the induction device, the induction device includes a sensor 532 provided on the connecting plate 200, and a detection block 531 is provided on the detection rod 520. The sensor 532 can detect the displacement generated by the detection block 531 relative to the sensor 532; among them, the sensor 532 determines whether there is a relative displacement between the detection rod 520 and the induction device by detecting the displacement of the detection block 531.

[0086] In order to enable the valve insertion detection device 500 to detect multiple batteries simultaneously, two detection rods 520 and two induction devices are arranged on the connecting plate 200 in the front-back direction, and the two induction devices can respectively detect the displacements of the two detection rods 520 relative to the induction devices in the up-down direction.

[0087] Among them, two lifting drive devices are arranged on the connecting plate 200 in the front-back direction; at this time, the two detection rods 520 can be independently detected.

[0088] This embodiment also provides a valve insertion detection method, which uses the above valve insertion detection device 500 to perform valve insertion detection work, including the following steps: a positioning step, driving the connecting plate 200 so that the detection rod 520 is directly above the position of the valve to be detected; a detection step, when the detection rod 520 is directly above the position of the valve to be detected, controlling the detection rod 520 to descend a specified distance; when the induction device detects that the detection rod 520 generates a displacement in the up-down direction relative to the induction device, stop descending the detection rod 520 and send an alarm signal.

[0089] Among them, in order to prevent other devices on the detection plate from interfering with the battery when controlling the detection rod 520 to descend through the detection plate, the detection step further includes: controlling the lifting drive device to drive the induction device and the detection rod 520 to descend a specified distance together.

[0090] In the sixth aspect of this embodiment, a valve inserting method is provided, which at least applies the above-mentioned pressing device 400 for valve inserting work, including the following steps: placing a safety valve, placing the safety valve to be inserted above the battery liquid injection hole; moving components, controlling the movement of the connecting plate 200 so that the sliding sleeve 450 moves above the liquid injection hole; sealing the liquid injection hole, controlling the sliding sleeve 450 to descend so that the lower end of the sliding sleeve 450 is sleeved around the safety valve to be inserted and seals the battery liquid injection hole; extracting gas, controlling an external air extraction device to extract the air in the first inner cavity so that the electrolyte gas in the battery liquid injection hole passes through the second inner cavity and the first inner cavity in sequence to the external air extraction device; pressing the safety valve, controlling the valve pressing rod 460 to descend and pressing the safety valve to be inserted into the liquid injection hole.

[0091] When applying the valve inserting method of this embodiment, during valve inserting, the connecting plate 200 can be controlled to descend so that the sliding sleeve 450 wraps the safety valve and the lower end of the sliding sleeve 450 abuts against the battery, and then the external air extraction device is controlled to extract the gas in the first inner cavity, so that the volatile gas of the electrolyte inside the battery passes through the second inner cavity and the first inner cavity in sequence and is extracted. After that, the connecting plate 200 is directly controlled to continue descending, so that the valve pressing rod 460 in the second inner cavity presses the safety valve into the liquid injection hole. In the whole pressing process, gas is extracted first and then the valve is pressed, effectively reducing the situation of the battery bulging due to electrolyte volatilization. At the same time, the valve pressing process is carried out in a vacuum environment, effectively reducing the possibility of air entering the battery.

[0092] Among them, the step of sealing the liquid injection hole includes: controlling the sliding sleeve 450 to descend so that the sealing ring 451 seals the gap between the sliding sleeve 450 and the battery; at this time, the sealing ring 451 can better seal the gap between the sliding sleeve 450 and the battery, further preventing air from infiltrating.

[0093] In the above method, in order to facilitate the arrangement of the pipeline of the air extraction device, the external air extraction device extracts the gas in the first inner cavity through the pipe connection part 401 provided on the base 110.

[0094] It can be understood that the above-mentioned grasping device 300 can be used to complete the step of placing the safety valve in the valve inserting method. At this time, the steps of preventing the safety valve are as follows: driving the connecting plate 200 so that the grasping rod 320 in the third inner cavity moves above the grasping position, controlling the vacuum chuck 330 to suck the safety valve to be inserted; after the vacuum chuck 330 sucks the safety valve to be inserted, driving the connecting plate 200 so that the grasping rod 320 moves above the battery liquid injection hole, and releasing the suction force of the vacuum chuck 330.

[0095] Before placing the safety valve, the feeding step can be performed first through the above-mentioned feeding device 100 to transport the safety valve to the grasping position, making it convenient for the grasping device 300 to grasp. At this time, the feeding step specifically includes: controlling the first push block 132 to push the safety valve above the positioning hole; controlling the conveying block 150 to move below the positioning hole so that the safety valve falls onto the conveying block 150 through the positioning hole; controlling the conveying block 150 to transport the safety valve that has fallen onto the conveying block 150 to the grasping position.

[0096] Further, in order to improve the accuracy of the falling position of the safety valve on the positioning hole, the feeding step includes: controlling the conveying block 150 to move below the positioning hole and controlling the valve pressing device 141 to press down so that the safety valve falls onto the conveying block 150 through the positioning hole.

[0097] Further, the feeding step includes controlling the second cylinder 160 to drive the conveying block 150 to move below the positioning hole.

[0098] Among them, the feeding step further includes: controlling the first cylinder 131 to drive the first push block 132 to push the safety valve above the positioning hole.

[0099] As Figure 6 shown, after completing the valve insertion work, it is also necessary to use the above-mentioned valve insertion detection device 500 to perform the detection step to detect whether the valve insertion is successful. The above-mentioned valve insertion detection step includes: a positioning step. After the safety valve is pressed into the liquid injection hole, drive the connecting plate 200 so that the detection rod 520 is directly above the position of the valve to be detected; a detection step. After the detection rod 520 is directly above the position of the valve to be detected, control the detection rod 520 to descend a specified distance; when the sensing device detects that the detection rod 520 generates a displacement in the up and down direction relative to the sensing device, stop descending the detection rod 520 and send out an alarm signal.

[0100] Among them, the above-mentioned detection step further includes: the detection step further includes: controlling the lifting drive device to drive the sensing device and the detection rod 520 to descend a specified distance together; at this time, by driving the lifting drive device to control the detection rod 520 to descend, it can effectively avoid the situation where other devices on the connecting plate 200 interfere with the battery when driving the detection rod 520 to descend by driving the connecting plate 200.

The moving device 600 can drive the connecting plate 200 to drive the grasping device 300, the pressing device 400, and the plug valve detection device 500 to move simultaneously.

[0102] When the plug valve device of the present invention is applied, during use, the battery can be placed below the moving device 600, and then the moving device 600 can sequentially move the grasping device 300, the pressing device 400, and the plug valve detection device 500 above the battery to perform processes such as placing the safety valve, pressing the valve, and plug valve detection on the battery in sequence. Since the corresponding devices are all integrated on the moving device 600, there is no need to move the battery during the three processes, and only the moving device 600 needs to be controlled to move different devices, effectively saving the time required to move the battery and the occupied space of the device for moving the battery.
