Description

Technical Field

[0001] This application relates to the field of battery assembly technology, and in particular to a battery safety valve assembly machine. Background Technology

[0002] The assembly and inspection of battery safety valves are crucial for ensuring battery safety performance and play a vital role in the entire battery production process. Currently, known safety valve assembly lines primarily rely on manual or semi-automated methods to install the safety valve caps. This process includes six steps: installing rubber gaskets, installing rubber caps, installing the front cover, the first gas test, ultrasonic welding, and the second gas test. The entire assembly process requires the collaborative work of more than ten employees, with each step handled by one to two workers. After all components are prepared, employees must manually transfer the packaged products to the next step and then install them themselves. This highly manual operation not only increases the company's cost burden, mainly due to the continuous rise in labor costs, but also presents numerous problems in production efficiency and quality stability.

In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0025] This utility model provides a battery safety valve assembly machine, comprising: a first turntable 110, on which a material belt is provided for conveying materials; a first vibratory plate 200, movably connected to the first turntable 110, the first vibratory plate 200 conveying an exhaust valve body onto the first turntable 110 via a finger cylinder; a clamp 300, movably connected to the first turntable 110, the clamp 300 for installing rubber caps; and a second vibratory plate 400, movably connected to the first turntable 110. A turntable 110 and a second vibrating plate 400 are used to install the front cover of the exhaust vent via a robotic arm; a third vibrating plate 500 is movably connected to the first turntable 110 and is used to install a washer via a robotic arm; a fourth vibrating plate 900 is movably connected to the fourth turntable and is used to install the rear cover of the exhaust vent; a welder 700 is connected to an airtightness tester 600 via a conveyor belt and is used to connect the exhaust vent body and the exhaust vent front cover.

[0026] Specifically, various materials and components are placed systematically at designated locations on the assembly line. Feeding is achieved via a vibratory feeder, precisely conveying the components to their predetermined positions. Subsequently, a sophisticated finger cylinder device firmly grips the component and places it onto a rotating turntable. The finger cylinder is an automated actuator that simulates human hand grasping motions, consisting of a cylinder body, a finger, and a control system. Upon receiving a control signal, the finger cylinder quickly and accurately grips the component and lifts it stably. Under the gripping action of the finger cylinder, the component is safely transferred to its designated position on the turntable. The turntable automatically completes the assembly process of the battery safety valve according to a preset program, including precise component installation, necessary pressure testing, and intelligent rejection of defective products. Ultrasonic welding technology is used in key assembly stages to ensure weld strength and product reliability. The entire assembly process, from component feeding, assembly, testing, and finished product output, requires only one operator for monitoring and management, significantly saving human resources. The assembly machine meets the requirements for the assembly, gas testing and welding of battery safety valves, which not only significantly improves production efficiency, but also effectively reduces the defect rate, thereby helping enterprises solve problems such as personnel shortage, low efficiency and high cost.

[0027] In some embodiments, the first turntable 110 has a circular structure, with a conveyor belt arranged around its periphery. The conveyor belt rotates along the first turntable 110 at a preset speed to transport materials. The first turntable 110 is an automated transfer device that enables rapid transfer and exchange of parts between multiple workstations. The first turntable 110 has multiple workstations, each corresponding to a different assembly or inspection process. As the first turntable 110 rotates, parts are sequentially transferred to each workstation, achieving continuous operation of the automated production line.

[0028] In some embodiments, the first vibratory plate 200, the second vibratory plate 400, and the third vibratory plate 500 are respectively connected around the outer periphery of the first turntable 110, and each of the first vibratory plate 200, the second vibratory plate 400, and the third vibratory plate 500 is correspondingly connected to a linear vibrator, which is used to convey materials. A vibratory plate is an automatic orientation and sorting feeding device that uses vibration to arrange scattered parts in an orderly manner and transport them to a designated position on the production line. The vibratory plate not only improves the efficiency of feeding but also ensures the accuracy and consistency of the parts, laying a solid foundation for the smooth operation of subsequent processes. Under the action of the vibratory plate, various parts are orderly transported to the beginning of the production line.

[0029] In some embodiments, the number of clamps 300 is two, and the two clamps 300 are arranged parallel to each other along the track.

[0030] In some embodiments, a second turntable 120 is also included. One end of a conveyor belt is connected to the first turntable 110, and the other end of the conveyor belt is connected to the second turntable 120. The conveyor belt is used to transport materials from the first turntable 110 to the second turntable 120. The second turntable 120 is an automated transfer device that enables the rapid transfer and exchange of parts between multiple workstations. The second turntable 120 has multiple workstations, each corresponding to a different assembly or inspection process. As the second turntable 120 rotates, parts are sequentially transferred to each workstation, realizing continuous operation of the automated production line.

[0031] In some embodiments, a sorting device 800 is also included. One end of the sorting device 800 is connected to an airtightness tester 600, and the other end is connected to a welder 700. The sorting device 800 is used to distinguish between good and defective products. After assembly, pressure testing becomes a critical step to ensure product quality. By applying a certain air pressure to the inside of the assembled product and monitoring changes in air pressure, the product's sealing performance and structural integrity are determined. If the product has leaks or structural defects, the air pressure will change abnormally. In this way, defective products can be detected and rejected in a timely manner, preventing them from flowing into subsequent processes.

[0032] Specifically, in the pressure-holding air test, when the sensor detects a defective product, it sends a signal to the control system. The control system then activates the actuator, which is a cylinder or push rod, to remove the defective product from the production line.

[0033] In some embodiments, a receiving component is movably disposed below the sorting device 800 to receive materials that have passed through the sorting device 800. Rejected defective products are collected in the receiving component for subsequent reprocessing or disposal. Simultaneously, relevant information about the defective products is recorded for quality traceability and improvement.

[0034] In some embodiments, a discharge port 910 is also included, which is connected to a welder 700, which is an ultrasonic welder 700. Ultrasonic welding is a process that uses energy generated by high-frequency vibration to melt materials and achieve a connection. During the welding process, the ultrasonic generator converts electrical energy into high-frequency vibration energy and transmits it to the parts to be welded through the welding head. Under the action of high-frequency vibration, the material on the surface of the parts is rapidly heated and melted, thereby achieving a strong connection. After ultrasonic welding, the product has completed all assembly and testing processes and becomes a qualified finished product. At this time, the finished product will be conveyed to the end of the production line for collection, packaging, and warehousing by operators or automated equipment.

[0035] In this embodiment, the welder 700 is used to weld the exhaust vent body and the exhaust vent front cover.

[0036] In some embodiments, a flipping device 920 is also included, which is disposed between the first vibrating plate 200 and the second vibrating plate 400. The flipping device 920 is used to flip the material on the material belt of the first turntable 110.

[0037] In some embodiments, an airtightness detector 600 is also included. The airtightness detector 600 is connected to the first turntable 110 via a conveyor belt. The airtightness detector 600 is used to detect the air pressure of the opening and closing valve.

[0038] Workflow:

[0039] The first vibratory feeder delivers the product to the positioning point, where a finger cylinder clamps the product into the first turntable. Manual placement of the tray positions the product, and a servo module clamps the product into the spray tank, rotating it to ensure even oil spraying. The second vibratory feeder delivers the product to the positioning point, where a finger cylinder clamps it into the first turntable. Defective or missing products are removed from the first turntable by a cylinder module. The product is then lifted, rotated 180 degrees, and placed back into the fixture. The third vibratory feeder lifts the gasket and places it into the product. The fourth vibratory feeder delivers the product to the positioning point, where a finger cylinder places it into the turntable. The product is then conveyed to an airtightness tester via a conveyor belt, with 15 products tested at a time. A sorting device with upper and lower limits removes defective products. Qualified products are then welded using an ultrasonic welder.
