Description

Technical Field

[0001] The invention relates to an automatic feeding and welding production line for explosion-proof valves, belonging to the technical field of battery explosion-proof valve welding. Background Art

[0002] The power battery system (power battery PACK, battery pack) is the core energy source for providing driving power for new energy vehicles and is one of the most critical components of new energy vehicles. The power battery system is mainly composed of battery modules, electrical systems, thermal management systems, shells, BMS and other components. The battery modules, electrical systems, thermal management systems and BMS are packaged in the shell to form the main body of the power battery system.

[0003] Power batteries generally include battery cover, explosion-proof valve, electrode assembly, etc. Among them, the operation of welding the explosion-proof valve on the battery cover is crucial, which is the key to ensure the safety of power batteries.

[0004] The welding process generally includes the pre-installation, spot welding, full welding and post-weld inspection of the battery cover and explosion-proof valve. In the traditional process, the automated process of the dividing plate is generally adopted, that is, the workstations for pre-installation, spot welding, full welding and post-weld inspection are arranged on the dividing plate, and the workstations are switched in sequence to achieve assembly welding.

[0005] With further improvements in the process, in order to meet the traceability of power batteries and the requirements of back-end assembly accuracy, it is necessary to add online identification of marked battery covers and post-weld shaping operations in traditional equipment. It is difficult to expand the workstations and install shaping stations on traditional dividing plates.

[0006] In this case, the solution of choosing a traditional linear production line can be compatible with the needs of online identification and detection. However, there are two linear workstation stepping methods in traditional linear production. One is the slide stepping method, that is, the battery cover is a supporting conveying structure, and the other is the interval conveyor belt method, that is, the battery cover is transported overhead. Among them, the supported conveying will make it difficult to arrange spot welding, full welding, and shaping stations, and it is impossible to achieve the support at the bottom to increase the welding quality and shaping effect, and the overhead conveyor belt is difficult to meet the positioning accuracy of the workstation switching.

[0007] In addition, traditional battery covers and explosion-proof valves are transported online in a directional manner. Therefore, the orientation and front and back of the materials are screened at the front end. When building the assembly production line, online material loading detection cannot be achieved, resulting in frequent interruptions of equipment operation and continuous production efficiency is difficult to ensure.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the relevant inventions are shown in the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] The present invention provides an explosion-proof valve automatic feeding welding production line, such as Figures 1 to 12 As shown, it includes an automated assembly welding device 1 and a battery cover plate supply device 2.

[0037] The automated assembly welding device 1 comprises an automated circulating conveyor line 3, a loading station 11 arranged in sequence along the feeding direction of the automated circulating conveyor line 3, a code scanning station 12, an explosion-proof valve assembly station 13, an explosion-proof valve spot welding station 14, an explosion-proof valve full welding station 15, a post-welding shaping station 16, a post-welding inspection station 17, and a classification unloading station 18.

[0038] The automated circulating conveyor line 3 includes two interlocking circulating material belts 31 arranged in parallel and at intervals, and a material positioning mechanism 32 arranged between the loading station and the code scanning station. Any interlocking circulating material belt is provided with a side stop 311 and a number of positioning protrusions 312 arranged at even intervals. The material positioning mechanism 32 includes a material positioning portion 320 with an inclined angle.

[0039] The code scanning station 12 includes a code scanning mechanism 120 .

[0040] The explosion-proof valve assembly station 13 comprises an explosion-proof valve supply device 131 and an explosion-proof valve transfer assembly mechanism 132 for picking up the explosion-proof valve 100 of the explosion-proof valve supply device and assembling it on the battery cover plate 200 .

[0041] The explosion-proof valve spot welding station 14 includes an explosion-proof valve spot welding mechanism 140 .

[0042] The explosion-proof valve full welding station 15 includes an explosion-proof valve full welding mechanism 150 .

[0043] The post-weld shaping station 16 includes a shaping mechanism 4, which includes a lifting shaping part 41 with a lifting displacement that runs through two linked circulating material belts and a top shaping part 42 with a lifting displacement that is arranged on the top of the lifting shaping part.

[0044] The post-weld inspection station 17 includes a post-weld image inspection mechanism 170 .

[0045] The sorting and unloading station 18 includes a good product conveying rail 181, an NG conveying belt 182, and an unloading turnover mechanism 183 for rotating and displacing between the sorting and unloading station and the good product conveying rail and between the sorting and unloading station and the NG conveying belt.

[0046] The battery cover plate supply device 2 comprises a battery cover plate conveyor line 20 for supplying battery cover plates, and a battery cover plate turnover mechanism 5 for circulating the battery cover plates between the battery cover plate conveyor line and a loading station.

[0047] The battery cover 200 is provided with a liquid injection hole 210, and the battery cover turnover mechanism 5 is provided with a picking-up part for picking up the battery cover. The picking-up part is provided with a plurality of negative pressure adsorption ends 51 and a gas detection channel 52 opposite to the liquid injection hole.

[0048] Specific implementation process and principle description: The battery cover conveyor line 20 conveys the supply material of the battery cover 200. When conveying to the end, the battery cover turnover mechanism 5 picks up the battery cover and places it on the loading station. When picking up, a number of negative pressure adsorption ends 51 perform negative pressure adsorption on the battery cover, and the air detection channel 52 is aligned with the position of the injection hole 210. The battery cover may have differences in forward and reverse directions and orientations. When the forward and reverse directions or orientation errors occur, the air detection channel 52 can identify and send a detection signal of correct or incorrect position to the rear end.

[0049] When the battery cover 200 circulates on the automated circulating conveyor line 3, it is first transferred to the loading station 11. At this time, the battery cover is limited and guided at both ends by the side stop 311. As the automated circulating conveyor line 3 runs, the battery cover will be pushed and positioned by the material positioning part 320 of the material positioning mechanism 32, so that the battery cover is facing away from the conveyor line and is abutted and limited by the positioning protrusion 312, thus meeting the high-precision positioning requirements after the battery cover is loaded.

[0050] After the loading is positioned, it passes through the subsequent stations in sequence. At the code scanning station 12, the code scanning mechanism 120 identifies and detects the identification code on the battery cover. The NG products are identified and do not participate in the operation of the subsequent stations until they are unloaded at the classification unloading station. The explosion-proof valve 100 is pre-assembled and loaded at the explosion-proof valve assembly station 13, and the explosion-proof valve supply device 131 supplies the explosion-proof valve. The explosion-proof valve transfer assembly mechanism 132 picks up the supplied explosion-proof valve and pre-assembles it on the battery cover 200.

[0051] After the explosion-proof valve is pre-assembled, the explosion-proof valve is spot-welded and fully welded in sequence by the explosion-proof valve spot welding mechanism 140 and the explosion-proof valve full welding mechanism 150 .

[0052] After the explosion-proof valve is welded, it enters the post-weld shaping station 16 , at which the post-weld shaping station realizes bidirectional matching shaping by relative displacement of the lifting shaping part 41 and the top shaping part 42 .

[0053] After shaping is completed, post-weld inspection is carried out by the post-weld image inspection mechanism 170. After the inspection, the unloading turnover mechanism 183 classifies and unloads the materials at the classification unloading station 18, and unloads the materials onto the good product conveyor rail 181 and the NG conveyor belt 182 respectively.

[0054] In a specific embodiment, the battery cover plate turnover mechanism 5 includes a turnover frame 50 and a linear slide 53 disposed on the turnover frame, and the linear slide is provided with at least two pick-up portions disposed in parallel and at intervals.

[0055] That is, it meets the requirements of synchronous picking and online turnover detection of at least two battery covers.

[0056] In a specific embodiment, the material-dispensing positioning portion 320 includes two inclined carrier blocks 321 disposed at intervals, and a material-dispensing brush 322 is disposed on any inclined carrier block.

[0057] The material shifting brush 322 can be moved and positioned without causing damage to the product surface, thus meeting the requirements of continuous shifting and material passing.

[0058] In a specific embodiment, the explosion-proof valve supply device 131 includes an explosion-proof valve supply belt 1311, a flexible vibration disk 1312 arranged at the discharge end of the explosion-proof valve supply belt, an explosion-proof valve image detection mechanism 1313 arranged on the top of the flexible vibration disk, at least one explosion-proof valve conveying line rail 6 with a plurality of explosion-proof valve carriers, and an explosion-proof valve turnover robot arm 1314 for rotating the explosion-proof valve between the flexible vibration disk and the explosion-proof valve conveying line rail.

[0059] That is, the explosion-proof valve is supplied through the explosion-proof valve supply belt 1311, and the explosion-proof valve falls on the flexible vibration plate 1312 for interval flattening. At this time, the position and positive and negative directions are detected through the explosion-proof valve image detection mechanism 1313, and the explosion-proof valve turnover robot arm 1314 picks up the explosion-proof valve and places it on the explosion-proof valve conveying line rail 6.

[0060] In a specific embodiment, the explosion-proof valve conveying line rail 6 is provided with a negative pressure suction flipping mechanism 60 for receiving the explosion-proof valve picked up by the explosion-proof valve turnover robot arm and flipping the explosion-proof valve carried on the explosion-proof valve carrier.

[0061] That is, the explosion-proof valve supply has a positive and a negative side, and the negative pressure suction flip mechanism 60 can realize that the reverse explosion-proof valve takes over and then flips to adjust the forward output of the explosion-proof valve.

[0062] In a specific embodiment, the explosion-proof valve transfer assembly mechanism 132 includes an assembly turnover part 1321 for turnover between the explosion-proof valve supply device and the automated circulation conveyor line, and an explosion-proof valve position angle guide mechanism 1322 located at the bottom of the running path of the assembly turnover part.

[0063] That is, the explosion-proof valve position angle guiding mechanism 1322 can realize the position data collection of the explosion-proof valve picked up on the assembly turnover part 1321, and adjust the position according to the rear-end assembly requirements, thereby improving the pre-assembly accuracy.

[0064] In a specific embodiment, the explosion-proof valve transfer assembly mechanism 132 includes an explosion-proof valve unloading cabin and a battery cover unloading cabin arranged on the turnover path of the assembly turnover part, and the assembly turnover part 1321 has a negative pressure turnover picking part 13210 for picking up the explosion-proof valve or the battery cover.

[0065] That is, when the battery cover is in the wrong direction or orientation, the battery cover can be unloaded at the explosion-proof valve pre-assembly station. The battery cover at this unloading position is only in the wrong direction and does not belong to NG products, which makes recycling more convenient.

[0066] In a specific embodiment, the explosion-proof valve spot welding mechanism 140 includes a spot welding machine 141 and a spot welding locking mechanism 142, the spot welding locking mechanism includes a spot welding base located at the top of the automated circulating conveyor line, and a spot welding lifting module with lifting displacement arranged at the bottom of the spot welding base; a spot welding cabin seat with a spot welding hollow portion is provided on the spot welding base, and the spot welding hollow portion is connected to a spot welding exhaust channel.

[0067] The explosion-proof valve full welding mechanism 150 includes a full welding machine 151 and a full welding locking mechanism 152. The full welding locking mechanism includes a full welding base located at the top of the automated circulating conveyor line, and a full welding lifting module with lifting displacement arranged at the bottom of the full welding base; a full welding cabin seat with a full welding hollow portion is provided on the full welding base, and the full welding hollow portion is connected to a spot welding exhaust channel.

[0068] Due to the use of a conveyor line with intervals, both spot welding and full welding can be carried out by the coordination of the jacking module and the welding cabin. This arrangement eliminates the defect of the traditional rotating pallet that cannot achieve two-way coordination, thereby ensuring the welding quality of spot welding and full welding operations.

[0069] In a specific embodiment, two electrode slots spaced apart from each other are provided on the battery cover, and a plurality of arc-shaped protrusions for cooperating with the electrode slots are respectively provided on the two linked circulating material belts.

[0070] The illustration of the arc-shaped protrusion is omitted in the accompanying drawings. The arc-shaped protrusion is a structure corresponding to the electrode slot, which can improve the mounting position accuracy and stability of the battery cover on the linked circulating material belt 31.

[0071] From the above description, it can be found that the material belt can be positioned and conveyed, so that the positioning accuracy is guaranteed while meeting the linkage and coordination requirements of the welding and shaping stations. The welding quality and shaping quality of the product are guaranteed, and the qualified rate is greatly improved. It meets the gas inspection requirements of the front and back and direction during the transfer, and no additional station is required for inspection. The completion of the direction inspection during the transfer process improves the operation efficiency. The unloading of battery covers with the wrong direction is compatible in the explosion-proof valve pre-assembly station, so that recycling and screening are more convenient and convenient, and the overall operation is smoother and more stable.

[0072] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that includes a list of elements includes not only those elements but also other elements not expressly listed, or also includes elements inherent to such process, method, article, or apparatus / device.

[0073] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
