Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery detection, and in particular to a battery conveying system for mass spectrometer analysis and detection. BACKGROUND

[0002] A battery refers to a cup, a groove or other container or part of a composite container containing an electrolyte solution and a metal electrode to generate current, which can convert chemical energy into electrical energy. With the development of science and technology, batteries have been increasingly widely used in mobile phones, automobiles and other fields and are closely related to human daily life. However, in the charge-discharge reaction of the battery, there may be a side reaction and gas generation, and the amount of gas gradually accumulates over time, which seriously damages the service life of the battery and may even cause safety problems.

[0003] The main sources of battery gas generation include oxygen release from electrode materials and decomposition of organic electrolyte and the like. These gases, as products of electrode reactions, can be used to inversely deduce the process of electrode reactions, and meanwhile, by identifying the gas-phase products through mass spectrometry and analyzing the process of catalytic reactions, the structural changes of electrode materials and the stability of electrolyte under potential cycling can be accurately identified.

[0004] A general detection device has only one vacuum mass spectrometry detection device. In the testing process, if the battery leaks, not only gas but also liquid may be leaked. To prevent the leaked solution from polluting the vacuum mass spectrometry detection device, the battery is usually placed in a jig, and the jig is tested together with the vacuum mass spectrometry detection device. In this way, even if the battery leaks, the jig can contain the leaked solution to avoid pollution of the vacuum mass spectrometry detection device.

[0005] However, in this way, if the jig is taken out as a whole every time, when the battery pack does not leak, all the qualified battery packs still need to be taken out from the jig for secondary operation, which is relatively complicated. If the jig and the battery are placed separately, the structures of the jig and the battery are different, and the clamping jaws required for transportation are also different, so two mechanical hands are required for independent transportation, which is complicated to control and reduces efficiency. SUMMARY

[0006] In order to improve the efficiency, the application provides a battery conveying system for mass spectrometer analysis and detection.

[0007] The battery conveying system for mass spectrometer analysis and detection provided by the application adopts the following technical scheme: A battery conveying system for mass spectrometer analysis and detection comprises a base, one end of the base is provided with a conveying belt for conveying batteries, the other end of the base is provided with a feeding station, the feeding station is provided with a jig for carrying batteries, the base is movably connected with a gripper for transferring batteries and jigs, the center of the gripper is provided with a plurality of suction cups for adsorbing batteries, and the two sides of the gripper are horizontally slidably connected with a plurality of pairs of side claws for clamping jigs.

[0008] By adopting the above technical scheme, the gripper is lowered above the battery, the suction cups adsorb and clamp the battery and transfer the battery above the jig, and the battery is placed on the jig. The side claws are opened and located on both sides of the jig, the side claws are closed to clamp both sides of the jig, and the gripper synchronously transports the jig and the suction cups. After testing, if the battery pack does not leak, the gripper can take out the battery alone through the suction cups, and the jig remains in the vacuum mass spectrometer detection equipment for next test. The gripper directly adsorbs and grabs the next batch of batteries through the suction cups and puts them into the jig in the vacuum mass spectrometer detection equipment, so that the jig does not need to be transported again, saving time and effort. When the battery pack leaks and contaminates the jig, the gripper can take out the battery and the jig together through the side claws. Through the arrangement of the suction cups and the side claws, the gripper can clamp and transport the battery and the jig respectively, one gripper can realize the transportation of two different structures, and the actual working condition is selected and adjusted to ensure the optimal process steps, thereby improving the work efficiency.

[0009] As a preferred, the suction cup is connected with the gripper in vertical sliding through a vertical cylinder, the side claw is connected with the gripper in horizontal sliding through a horizontal cylinder, a vertical rod is fixed on the suction cup and arranged vertically, a clamping switch electrically connected with the horizontal cylinder is arranged on the lower surface of the gripper, when the suction cup is at the uppermost position, the vertical rod is in contact with the clamping switch, and the clamping switch is opened; a horizontal rod is fixed on the side claw, and an adsorption switch is arranged on the gripper, when the pair of side claws move to the farthest distance, the horizontal rod is in contact with the adsorption switch, and the adsorption switch is opened.

[0010] By adopting the above technical scheme, when the suction cup is at the uppermost position, it is in the standby initial state, and when the side claw is in the open position, it is in the standby initial state. When the suction cup is in the standby initial state, the clamping switch is in the open state, and at this time, the horizontal cylinder can freely extend and retract, that is, the side claw can be closed or opened. When the suction cup is lowered, it means that the gripper needs to adsorb the battery, at this time, the side claw does not need to perform the action. At this time, the vertical rod is separated from the clamping switch, the clamping switch is closed, the horizontal cylinder is disconnected, and the horizontal cylinder cannot be started, that is, the side claw cannot be closed or opened. Similarly, when the side claw is in the open standby state, the suction cup can freely move up and down to adsorb the battery, and when the side claw is closed to clamp the jig, the suction cup is locked and cannot move. The suction cup and the side claw are interlocked, when one side performs the grabbing and transporting operation, the other side is locked and cannot move, thereby avoiding mutual interference.

[0011] Preferably, the base is provided with a jig stacking station, which includes a number of vertically arranged limiting rods that form a stacking area, and the jigs are stacked in the stacking area.

[0012] By adopting the above technical solution, the gripper removes the fixture from the stacking station and places it on the loading station to await the addition of batteries, which is convenient to use.

[0013] Preferably, the stacking area is provided with a slide rail, and a limiting plate located at the end of the slide rail is vertically fixed on the stacking station.

[0014] By adopting the above technical solution, operators can first stack several jigs from the outside, and then slide them into the stacking station via slide rails for replenishment, which is convenient to use.

[0015] Preferably, the fixture has a plurality of receiving slots for holding batteries, the number of suction cups is the same as the number of receiving slots, and the distribution position of the suction cups is the same as the distribution position of the receiving slots on the fixture.

[0016] By adopting the above technical solution, the fixture can carry multiple batteries at a time, and the grippers can also pick up multiple batteries at a time and put them into the fixture at once, thus improving work efficiency.

[0017] Preferably, a discharge guide rail is provided between the conveyor belt and the loading station, and a discharge plate is slidably connected to the discharge guide rail. The sliding direction of the discharge plate is parallel to the conveying direction of the conveyor belt. The discharge plate is provided with a number of discharge slots.

[0019] Preferably, the discharge guide rails are provided in multiple ways, and each discharge guide rail is provided with a discharge plate.

[0020] By adopting the above technical solution, multiple discharge guide rails can be used alternately, improving work efficiency.

[0021] Preferably, a preliminary inspection platform is provided between the conveyor belt and the discharge guide rail. A transfer plate is rotatably connected to the preliminary inspection platform. The center of the transfer plate is vertically rotatably connected to the preliminary inspection platform. Preliminary inspection slots for accommodating batteries are respectively opened at both ends of the transfer plate. One end of the transfer plate faces the conveyor belt and the other end faces the discharge guide rail. A detection probe is provided on the preliminary inspection platform above the transfer plate. The detection probe is directly opposite the end of the transfer plate near the discharge guide rail.

[0022] By adopting the above technical solution, the batteries on the conveyor belt are transported to the initial inspection slot at one end of the transfer plate. The transfer plate rotates 180 degrees, and the detection probe performs a preliminary inspection of the batteries on the transfer plate. During the inspection process, the end of the transfer plate closest to the conveyor belt is reloaded with batteries from the conveyor belt. Inspection is performed at one end of the transfer plate while loading occurs at the other. The rotation of the transfer plate changes the positions of both ends, thus forming a continuous operation and improving efficiency.

[0023] Preferably, the initial inspection station is equipped with a sorting robot at the end near the discharge guide rail, and a residual material belt is provided parallel to one side of the conveyor belt, with a single-piece qualified station fixed next to the residual material belt.

[0024] By adopting the above technical solution, the sorting robot grabs and transports the batteries that have been detected by the detection probe. If the batteries are qualified, they are transported to the discharge plate; if they are not qualified, they are transported to the waste material belt for output.

[0025] Preferably, an adjustment frame is slidably connected to one end of the conveyor belt near the transfer plate, and several adjustment suction cups are slidably connected horizontally on the adjustment frame. The sliding direction of the adjustment frame is parallel to the conveying direction of the conveyor belt, and the sliding direction of the adjustment suction cups is perpendicular to the conveying direction of the conveyor belt.

Detailed Implementation

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] Example

[0032] This application discloses a battery delivery system for mass spectrometer analysis and detection, referring to... Figures 1 to 3 The system includes a base 1, on which a conveyor belt 2, a preliminary inspection table 8, a discharge guide rail 7, and a loading station 3 are sequentially arranged. A gripper 5 is movably connected to the end of the base 1 near the loading station 3, and a fixture 4 for carrying batteries is placed inside the loading station 3. The gripper 5 can slide horizontally and vertically via the guide rail.

[0033] Reference Figures 1 to 3 Conveyor belt 2 transports goods towards the initial inspection table 8. A position probe 23 and an adjustment frame 21 are fixed above the end of conveyor belt 2 near the initial inspection table 8. The adjustment frame 21 is located between the position probe 23 and the initial inspection table 8. The adjustment frame 21 is slidably connected to the conveyor belt 2 via a guide rail, and the sliding direction of the adjustment frame 21 is parallel to the conveying direction of the conveyor belt 2. Two adjustment suction cups 22 are slidably connected to the adjustment frame 21 via the guide rail. The sliding direction of the two adjustment suction cups 22 is perpendicular to the conveying direction of the conveyor belt 2, and the adjustment suction cups 22 are electrically connected to the position probe 23.

[0034] Reference Figures 1 to 3 The battery is placed at one end of the conveyor belt 2 and transported towards the adjustment frame 21. The position probe 23 takes a picture of the battery and identifies its location, and transmits the information to the adjustment suction cup 22. The adjustment suction cup 22 and the adjustment frame 21 work together to adjust the position of the adjustment suction cup 22 so that the adjustment suction cup 22 is located directly above the battery to pick up the battery and transport it to the initial inspection table 8.

[0035] Reference Figures 1 to 3A transfer plate 81 is rotatably connected to the initial inspection table 8. The center of the transfer plate 81 is vertically rotatably connected to the initial inspection table 8. Two initial inspection slots 811 for accommodating batteries are respectively opened at both ends of the transfer plate 81. One end of the transfer plate 81 faces the conveyor belt 2, and the other end faces the discharge guide rail 7. A detection probe 82 is provided on the initial inspection table 8 above the transfer plate 81, and the detection probe 82 is directly opposite the end of the transfer plate 81 near the discharge guide rail 7. The suction cup 22 is adjusted to transport the batteries into the two initial inspection slots 811 of the transfer plate 81 near the conveyor belt 2. The transfer plate 81 rotates 180 degrees, aligning the unloaded end with the conveyor belt 2 to wait for the next pair of batteries. The loaded end of the transfer plate 81 rotates to be below the detection probe 82, and the detection probe 82 detects the batteries.

[0036] Reference Figures 1 to 3 A sorting robot 83 is installed at the end of the initial inspection station 8 near the discharge guide rail 7. A residual material belt 84 is installed parallel to one side of the conveyor belt 2, and a single-item qualified station 85 is fixed next to the residual material belt 84. The sorting robot 83 transfers the inspected batteries. If two batteries are both unqualified, they are transferred to the residual material belt 84 for output. If one battery is unqualified, it is output through the residual material belt 84, while the qualified battery is placed on the single-item qualified station 85 until the next single qualified battery appears, at which point it is transferred to the discharge guide rail 7. If both batteries are qualified, they are conveyed to the discharge guide rail 7.

[0037] Reference Figures 1 to 3 The discharge guide rails 7 are provided in two parallel sections. A discharge plate 71 is slidably connected to each other on the discharge guide rails 7, and the sliding direction of the discharge plate 71 is parallel to the conveying direction of the conveyor belt 2. Several discharge slots 711 for accommodating batteries are provided on the discharge guide rails 7. In this application, there are six discharge slots 711 in total, arranged in two rows of three.

[0038] Reference Figures 1 to 3 The discharge plate 71 conveys the batteries to one end near the loading station 3. The grippers 5 grasp the batteries on the discharge plate 71 and convey them to the loading station 3. The center of the grippers 5 is equipped with several suction cups 51 for adsorbing the batteries. The number of suction cups 51 is the same as the number of discharge troughs 711, and the distribution of the suction cups 51 is consistent with the distribution of the discharge troughs 711 on the discharge plate 71. Several pairs of side claws 52 for clamping the fixture 4 are horizontally slidably connected to both sides of the grippers 5.

[0039] Reference Figures 1 to 3The suction cup 51 is vertically slidably connected to the gripper 5 via a vertical cylinder 53, and the side gripper 52 is horizontally slidably connected to the gripper 5 via a horizontal cylinder 54. A vertically arranged vertical rod 55 is fixed on the suction cup 51, and a gripping switch 56 electrically connected to the horizontal cylinder 54 is provided on the lower surface of the gripper 5. When the suction cup 51 is at its highest position, the vertical rod 55 abuts against the gripping switch 56, and the gripping switch 56 is turned on. A horizontal rod 57 is fixed on the side gripper 52, and an adsorption switch 58 is provided on the gripper 5. When the pair of side grippers 52 move to their farthest distance in opposite directions, the horizontal rod 57 abuts against the adsorption switch 58, and the adsorption switch 58 is turned on.

[0040] Reference Figures 1 to 3 When suction cup 51 is at its highest position, it is in the initial standby state. When side claw 52 is in the open position, it is also in the initial standby state. When suction cup 51 is in the initial standby state, clamping switch 56 is in the open state, allowing the horizontal cylinder 54 to extend and retract freely, meaning side claw 52 can tighten or open. When suction cup 51 descends, it indicates that claw 5 is about to pick up the battery; at this time, side claw 52 does not need to perform any action. At this time, vertical rod 55 separates from clamping switch 56, clamping switch 56 closes, horizontal cylinder 54 is disconnected, and horizontal cylinder 54 cannot be activated, meaning side claw 52 cannot tighten or open. Similarly, when side claw 52 is in the open standby state, suction cup 51 can move freely up and down to pick up the battery. When side claw 52 retracts to clamp the fixture 4, suction cup 51 is locked and cannot move. Suction cup 51 and side claw 52 are interlocked; when one is performing a gripping and transport operation, the other is locked and cannot move, thus avoiding mutual interference.

[0041] Reference Figures 1 to 3 The fixture 4 has several receiving slots 41 for holding batteries. The number of receiving slots 41 is the same as the number of discharge slots 711, and the distribution position of the receiving slots 41 is the same as the distribution position of the discharge slots 711 on the discharge plate 71. The gripper 5 can grab all the batteries on the discharge plate 71 at once and place them all on the fixture 4 at one time, making loading convenient and quick.

[0042] Reference Figures 1 to 3 The base 1 is equipped with a jig stacking station 6, which includes several vertically arranged limiting rods 61 surrounding a stacking area 62, within which jigs 4 are stacked. A slide rail 63 is provided within the stacking area 62, and a limiting plate 64 is vertically fixed at the end of the slide rail 63 on the stacking station. A gripper 5 removes the jigs 4 from the stacking station and places them on the loading station 3 to await battery addition, making it convenient to use. Operators can stack several jigs 4 from the outside and then slide them into the stacking station via the slide rail 63 for replenishment, also convenient to use.

[0043] The implementation principle of a battery transport system for mass spectrometry analysis in this application embodiment is as follows: Batteries are synchronously placed on conveyor belt 2 by an external robotic arm or manually, and then placed on transfer plate 81 via adjusting suction cup 22. After preliminary testing by detection probe 82, unqualified batteries are discharged through residual material belt 84. Qualified batteries are transported to discharge plate 71 for arrangement by sorting robotic arm 83. Gripper 5 first picks up a fixture 4 from fixture stacking station 6 and places it into loading station 3. Gripper 5 then picks up all batteries from discharge plate 71 at once and transfers them all to fixture 4. Gripper 5 then transfers the loaded fixture 4 for mass spectrometry testing. If the batteries are qualified after mass spectrometry testing, gripper 5 picks up and removes all batteries. If the batteries are unqualified and leakage occurs, gripper 5 removes fixture 4 along with the batteries using side gripper 52.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
