Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a high-speed and stable alkaline battery screening device. Background Technology

[0002] Ensuring product quality is paramount in the production of alkaline batteries. Since defective products may emerge during production, their entry into the market can severely impact consumer experience and the product's reputation. Therefore, rigorous screening is necessary before alkaline batteries leave the factory to eliminate defective products.

[0003] Traditional screening methods rely primarily on manual operation, requiring workers to inspect each battery individually to identify and reject defective products. However, this manual screening method has significant limitations. First, manual screening is slow and cannot meet the demands of large-scale production, especially on high-volume production lines, where it becomes a bottleneck restricting production efficiency. Furthermore, with rising labor costs, reliance on manual screening increases production costs, hindering companies from reducing costs and improving market competitiveness. Additionally, manual screening is susceptible to worker fatigue and distraction, making it difficult to guarantee accuracy and consistency, potentially leading to missed defects or misjudgments of qualified products.

[0004] Given the aforementioned problems, manual screening methods can no longer meet the demands of modern production lines for high efficiency, low cost, and high accuracy. Therefore, developing an automated, high-speed, and stable alkaline battery screening device to replace traditional manual screening methods has become an inevitable trend in the industry.

[0020] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0021] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a high-speed and stable alkaline battery screening device, including a feeding conveyor mechanism 1, a sorting and positioning turntable 2, a screening and classification mechanism 3, a defective product channel 4, and a qualified product channel 5. The feeding conveyor mechanism 1 is used to longitudinally feed several batteries arranged in a straight line to the area below the sorting and positioning turntable 2. The sorting and positioning turntable 2 is used to transfer the batteries one by one and allow them to be inspected by a visual inspection device (not shown in the figure). The screening and classification mechanism 3 is used to guide the qualified batteries determined to be qualified after visual inspection on the sorting and positioning turntable 2 into the qualified product channel 5, and to guide the unqualified batteries into the defective product channel 4. The automated feeding and conveying mechanism 1 and the sorting and positioning turntable 2 enable rapid and continuous conveying and positioning of batteries, significantly improving the speed of the screening process and meeting the needs of high-speed production lines. Visual inspection equipment is used to accurately inspect the batteries, ensuring the accuracy of the screening results and effectively reducing the rate of missed defects. The automated screening process reduces the need for manual operation, lowers labor costs, reduces the labor intensity of workers, and improves the safety of the working environment. Precise screening and classification ensures that only qualified batteries can enter the subsequent production process, thereby improving the overall quality of the final product.

[0022] In this embodiment, it is further preferred that the feeding and conveying mechanism 1 includes a base 11, supporting side plates 12, sprockets 13, and rollers 14. The base 11 is provided with symmetrical supporting side plates 12, and a drive shaft 15 is disposed between the two supporting side plates 12. The symmetrically arranged supporting side plates 12 provide a stable structural foundation, ensuring the stability and symmetry of the entire conveying mechanism during operation, reducing deviations and malfunctions caused by structural asymmetry. The drive shaft 15 is fixedly connected to the sprockets 13, ensuring efficient and stable power transmission, reducing energy loss, and improving the overall working efficiency of the conveying mechanism. Hollow pin chains are wound around the front and rear sprockets 13. The design of the hollow pin chains makes the chain... Lighter and easier to maintain, the chain's flexibility allows for stable operation at different speeds, adapting to varying production speed requirements. Rollers 14 connect the hollow pin chains on the left and right sides, arranged laterally. Adjacent rollers 14 form a limiting slot for placing batteries. The batteries are parallel to the rollers 14, ensuring neat arrangement during transport and precise battery positioning. This ensures the batteries maintain the correct orientation and position during transport, preventing displacement or misalignment. Precise battery positioning and parallel arrangement reduce collisions and friction during transport, lowering the risk of battery damage, protecting battery integrity, and improving product quality.

[0023] In this embodiment, it is further preferred that the top of the support side plate 12 is also provided with a guide side plate 16. The guide side plate 16 is arranged longitudinally on the battery conveying path. The two guide side plates 16 are symmetrically arranged on the left and right sides and have a spacing adapted to the battery length. The input end of the guide baffle is provided with an inclined guide surface. The longitudinal arrangement of the guide side plate 16 ensures that the battery maintains a straight movement on the conveying path, reduces the offset and vibration of the battery during the conveying process, and thus improves the accuracy and stability of the conveying process.

[0024] In this embodiment, it is further preferred that the base 11 is also provided with a mounting frame 6, and the material distribution and positioning turntable 2 is set on one side of the mounting frame 6 and driven by the first motor 21 to rotate intermittently. This can achieve precise control of the battery positioning and material distribution process, ensuring the positioning accuracy and stability of the battery during the transportation process. The material distribution and positioning turntable 2 rotates counterclockwise. The combination of intermittent rotation and counterclockwise rotation of the material distribution and positioning turntable 2 improves the material distribution efficiency, allowing the batteries to be accurately distributed to different channels according to a predetermined rhythm and sequence. The material distribution and positioning turntable 2 is gear-shaped and has evenly spaced limiting grooves 22 around its outer circumference. Each limiting groove 22 is embedded with a magnetic adsorption block, providing a strong and stable battery positioning method, ensuring that the batteries are not affected by vibration or impact during the material distribution process. When displacement occurs, the material distribution and positioning turntable 2 is located at the transmission end of the feeding conveyor mechanism 1. The thickness of the material distribution and positioning turntable 2 is less than the length of the battery. The bottom of the material distribution and positioning turntable 2 is pre-set to form a picking station, that is, when the limiting groove 22 of the material distribution and positioning turntable 2 rotates to this station, it can precisely adsorb and pick up the battery at that position. This provides a simple and effective battery positioning mechanism, enabling automated picking, reducing manual operation, improving the automation level and operating efficiency of the production line, and ensuring the accurate positioning and stable transmission of the battery during the picking process. The material distribution and positioning turntable 2 design in this embodiment, with its ingenious structural design, compact layout, and complex and precise picking action achieved by a simple structure, demonstrates that while maintaining ease of operation, it can meet the needs of efficient and precise industrial automation. This design not only improves production efficiency but also enhances the reliability and economy of the equipment.

[0025] In this embodiment, it is further preferred that the screening and sorting mechanism 3 includes a second motor 31, an eccentric shaft 32, a pusher block 33, a guide block 34, a first limiting block 35, and a second limiting block 36. The first limiting block 35, the second limiting block 36, and the pusher block 33 are all arranged and fixedly assembled on the same side as the material distribution and positioning turntable 2. A first traveling channel 7 is formed between the first limiting block 35 and the material distribution and positioning turntable 2, and a second traveling channel 8 is formed between the second limiting block 36 and the material distribution and positioning turntable 2. A downwardly inclined defective product channel 4 is formed between the first limiting block 35 and the second limiting block 36, and a qualified product channel 5 is formed between the guide block 34 and the second limiting block 36. The defective product channel 4 is located between the first traveling channel 7 and the second traveling channel 8. The end of the guide block 34 is provided with an arc-shaped guide hook, which is used for material distribution at the material picking station. After passing inspection, the batteries picked up by the positioning turntable 2 pass through the first travel channel 7 and the second travel channel 8 in sequence, and are then guided into the qualified product channel 5 by the guide block 34. Batteries picked up by the sorting positioning turntable 2 at the picking station that fail inspection pass through the first travel channel 7 and are then pushed into the defective product channel 4 by the pusher block 33. The design of the screening and sorting mechanism 3 is ingeniously coordinated with the sorting positioning turntable 2. Under the intermittent rotation of the sorting positioning turntable 2, the batteries can dynamically enter the corresponding channels, achieving efficient dynamic coordination and rapid classification of batteries. Qualified and defective products can be quickly and accurately diverted into their respective channels, greatly improving screening efficiency. Through ingenious layout and mechanism design, the screening and sorting mechanism 3 simplifies the sorting operation, reduces complex mechanical parts and operating steps, and makes the entire sorting process more concise and efficient.

[0026] In this embodiment, it is further preferred that the pusher block 33 is rotatably engaged with the mounting frame 6 via a positioning pin. The pusher block 33 has an oblong hole. The second motor 31 is located on the other side of the mounting frame 6. The output shaft of the second motor 31 is connected to an eccentric shaft 32. One end of the eccentric shaft 32 is inserted into the oblong hole of the pusher block 33. The pusher block 33 has two symmetrical push rods 37. The material distribution and positioning turntable 2 is located between the two push rods 37. The symmetrical push rod design not only provides structural balance but also ensures the uniformity and stability of the pushing action, avoiding battery damage or equipment wear caused by uneven force. The end of the push rod 37 has a concave arc-shaped surface. The second motor 31 drives the pusher block 33 to move through the eccentric shaft 32 and pushes the battery into the defective product channel 4 through the head of its push rod 37. The small displacement of the eccentric shaft 32 is amplified by the linkage mechanism, so that the pusher block 33 can achieve a wide range of pushing action. This design utilizes simple mechanical principles to achieve the maximum output with the minimum input, improving the efficiency and response speed of the action. The cooperation structure between the eccentric shaft 32 and the linkage is simple, reducing complex mechanical parts, reducing the failure rate and maintenance costs. At the same time, this structure has high reliability and can maintain stable performance during long-term production. It's worth noting that, compared to the commonly used cylinder-driven feeding method, which has a maximum speed of 300 pieces / minute, this method requires the equipment to slow down to 300 pieces / minute for rejection after detecting defective products, before accelerating production again. This directly impacts the overall production efficiency of the line. Through the cooperation of the eccentric shaft 32 and the linkage mechanism, the screening and sorting mechanism 3 can achieve high-speed, large-displacement movement. This simple and effective structure allows for a rejection speed of 1000 pieces / minute, more than three times the speed of the cylinder-driven feeding method. This structure also features high-speed stability, allowing the production line to maintain continuous high-speed operation without slowing down when rejecting defective products, significantly improving overall production efficiency.

[0027] In a further preferred embodiment, the device also includes a guide rail 9 and a defective product storage device 10. The guide rail 9 is vertically fixed below the mounting frame 6 and located behind the base 11. The guide rail 9 has a serpentine, continuously winding guide channel. The upper entrance of the guide channel communicates with the defective product channel 4, and the lower exit of the guide channel faces the defective product storage device 10. This structure ensures that defective products can still enter the storage area in an orderly manner after high-speed screening, avoiding chaos and accumulation caused by high-speed rejection. Due to the guiding effect of the guide rail 9, defective products are aligned in direction when entering the defective product storage device 10, reducing... The risk of short circuits caused by connecting battery terminals end-to-end is eliminated, ensuring the safety of defective product storage. Specifically, the defective product storage device 10 includes a belt conveyor and three limiting baffles arranged in a U-shape on the belt conveyor. The guide rail 9 is located between the left and right limiting baffles, with its lead-out end facing the belt conveyor. This layout helps to arrange and fix defective products in an orderly manner, preventing them from moving and becoming disordered during storage. The orderly defective product handling process improves the overall coordination of the production line, enabling each link in the production line to cooperate more smoothly and reducing production interruptions caused by improper handling of defective products.

[0028] In actual operation, when the equipment starts running, the batteries are fed into the system through the feeding conveyor mechanism 1. This mechanism is responsible for arranging the batteries longitudinally along the conveyor belt, preparing them for the next step of the sorting process. The arranged batteries reach the sorting and positioning turntable 2, which is driven by a motor and rotates intermittently, causing the batteries to pass through the detection port of the vision inspection device set on one side of the equipment one by one, thereby completing the quality inspection. According to the vision inspection results, qualified batteries are guided into the qualified product channel 5 by the guide block 34, while unqualified batteries are pushed into the defective product channel 4 by the pusher block 33. The defective product channel 4 will then remove the unqualified batteries. The battery is guided to the guide rail system 9, which is designed in a serpentine pattern to transport defective products to the defective product storage device 10 in an orderly manner through continuous looping. During this process, as the battery rotates with the material distribution and positioning turntable 2, the pusher block 33 is in a standby state, ready to respond to the detection results. Once the visual inspection equipment determines that a battery is defective, the pusher block 33 will receive a signal and prepare to perform the pushing action. Under the push of the pusher block 33, the defective battery is pushed away from the first travel channel 7 to the defective product channel 4. This action is quick and accurate, ensuring that defective products do not enter the subsequent production process.

[0029] It is worth noting that the technical features of motors, vision inspection equipment, etc. involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0030] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
