Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a high-speed and stable alkaline battery screening device. Background Art

[0002] In the production process of alkaline batteries, it is crucial to ensure product quality. Since defective products may appear during the production process, if these defective products enter the market, it will seriously affect the consumer experience and the market reputation of the product. Therefore, alkaline batteries need to be strictly screened before leaving the factory to eliminate defective products.

[0003] Traditional screening methods mainly rely on manual operations, and workers need to check each battery one by one to identify and remove defective products. However, this manual screening method has obvious limitations. First, manual screening is slow and cannot meet the needs of large-scale production. Especially on high-volume production lines, manual screening has become a bottleneck restricting production efficiency. In addition, with the increase in labor costs, relying on manual screening methods has led to increased production costs, which is not conducive to companies reducing costs and improving market competitiveness. At the same time, manual screening is affected by factors such as worker fatigue and distraction, and it is difficult to ensure the accuracy and consistency of screening, which may lead to missed inspections of defective products or misjudgment of qualified products.

[0004] In view of the above problems, manual screening methods can no longer meet the needs 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 the traditional manual screening method has become an inevitable trend in the development of the industry.

The feeding conveying mechanism 1 is used to longitudinally arrange a plurality of batteries in a line and send them one by one to the bottom of the material dividing and positioning turntable 2, the material dividing and positioning turntable 2 is used to transfer the batteries one by one and make them 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 on the material dividing and positioning turntable 2 after visual inspection into the qualified product channel 5, and guide the unqualified batteries into the defective product channel 4, through Through the automated loading and conveying mechanism 1 and the material distribution and positioning turntable 2, the rapid and continuous conveying and positioning of the batteries are realized, which greatly improves the speed of the screening process and meets the needs of high-speed production lines. The visual inspection equipment is used to accurately inspect the batteries, which ensures the accuracy of the screening results and effectively reduces the missed detection rate of defective products. The automated screening process reduces the need for manual operation and reduces labor costs. At the same time, it reduces the labor intensity of workers and improves the safety of the working environment. Through precise screening and classification, it ensures that only qualified batteries can enter the subsequent production process, thereby improving the overall quality of the final product.

[0022] It is further preferred in this embodiment that the feeding conveying mechanism 1 includes a base 11, a supporting side plate 12, a sprocket 13, and a roller 14. The base 11 is provided with a left-right symmetrical supporting side plate 12, and a transmission shaft 15 is provided between the two supporting side plates 12. The left-right symmetrical supporting side plates 12 provide a stable structural foundation, ensuring the stability and symmetry of the entire conveying mechanism during operation, reducing deviations and failures caused by structural asymmetry, and the transmission shaft 15 is fixedly connected to the sprocket 13, ensuring the high efficiency and stability of power transmission, reducing energy loss, and improving the working efficiency of the entire conveying mechanism. A hollow pin chain is wound around the front and rear sprockets 13, and the design of the hollow pin chain makes the chain It is lighter and easier to maintain.

The two guide side plates 16 are symmetrically arranged on the left and right and have a spacing adapted to the length of the battery. 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 linear motion on the conveying path, reduces the displacement and vibration of the battery during the conveying process, and thus improves the accuracy and stability of the conveying process.

[0024] It is further preferred in the present embodiment that a mounting frame 6 is further provided on the base 11, and the material distribution positioning turntable 2 is arranged on one side of the mounting frame 6 and is driven by a first motor 21 to rotate intermittently, which can realize precise control of the battery positioning and material distribution process, and ensure the positioning accuracy and stability of the battery during the conveying process. The material distribution positioning turntable 2 rotates counterclockwise, and the intermittent rotation of the material distribution positioning turntable 2 is combined with the counterclockwise rotation to improve the distribution efficiency, so that the batteries can be accurately distributed to different channels according to a predetermined rhythm and sequence. The material distribution positioning turntable 2 is gear-shaped and has an outer periphery provided with limiting grooves 22 evenly spaced around the circumferential direction. A magnetic adsorption block is embedded in each of the limiting grooves 22, which provides a strong and stable battery positioning method to ensure that the battery will not be affected by vibration or impact during the distribution process. The material distribution and positioning turntable 2 is arranged at the transmission end of the feeding and conveying 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 preset to form a material picking station, that is, the limiting groove 22 of the material distribution and positioning turntable 2 can just adsorb and pick up the battery at this position when it rotates to this station, providing a simple and effective battery positioning mechanism, so that automatic material picking can be carried out, reducing manual operation, improving the automation level and operating efficiency of the production line, and ensuring the precise positioning and stable transmission of the battery during the material picking process. The design of the material distribution and positioning turntable 2 in this embodiment, with its ingenious structural design, compact layout and complex and precise material picking actions realized by simple structure, shows that it can meet the needs of efficient and precise industrial automation while maintaining ease of operation. This design not only improves production efficiency, but also improves the reliability and economy of the equipment.

[0025] It is further preferred in the present embodiment that the screening and classification mechanism 3 includes a second motor 31, an eccentric shaft 32, a pushing block 33, a guiding 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 pushing block 33 are all arranged and fixedly assembled on the same side of the material distribution positioning turntable 2. A first travel channel 7 is formed between the first limiting block 35 and the material distribution positioning turntable 2, and a second travel channel 8 is formed between the second limiting block 36 and the material distribution positioning turntable 2. A defective product channel 4 inclined downward is formed between the first limiting block 35 and the second limiting block 36, and a qualified product channel 5 is formed between the guiding block 34 and the second limiting block 36. The defective product channel 4 is located between the first travel channel 7 and the second travel channel 8. The end of the guiding block 34 is provided with an arc-shaped guide hook, which is divided at the material taking station After the batteries sucked by the positioning turntable 2 are tested and found to be qualified, they can pass through the first travel channel 7 and the second travel channel 8 in sequence, and then be guided into the qualified product channel 5 by the guide block 34. After the batteries sucked by the material distribution positioning turntable 2 at the material picking station are tested and found to be unqualified, they can pass through the first travel channel 7 and then be pushed into the defective product channel 4 by the pushing block 33. The design of the screening and classification mechanism 3 is cleverly coordinated with the material distribution positioning turntable 2. Under the intermittent rotation of the material distribution positioning turntable 2, the batteries can dynamically enter the corresponding channels, realizing efficient dynamic coordination and realizing rapid classification of the batteries. Qualified products and defective products can be quickly and accurately diverted to their respective channels, greatly improving the screening efficiency. Through clever layout and mechanism design, the screening and classification mechanism 3 simplifies the material distribution operation, reduces complex mechanical components and operating steps, and makes the entire material distribution process more concise and efficient.

[0026] It is further preferred in this embodiment that the pusher block 33 is rotatably matched with the mounting bracket 6 through a positioning pin shaft, the pusher block 33 is provided with a waist-shaped hole, the second motor 31 is arranged on the other side of the mounting bracket 6, the output shaft of the second motor 31 is connected to the eccentric shaft 32, one end of the eccentric shaft 32 is inserted into the waist-shaped hole of the pusher block 33, the pusher block 33 is provided with two left-right symmetrical push rods 37, the material distribution positioning turntable 2 is located between the two push rods 37, and the left-right symmetrical push rod 37 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 is provided with a concave arc surface. The second motor 31 drives the push block 33 to move through the eccentric shaft 32 and can push 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 connecting rod mechanism, so that the push block 33 can achieve a wide range of pushing actions. This design utilizes simple mechanical principles to achieve maximum output with minimum input, thereby improving the efficiency and response speed of the action. The matching structure of the eccentric shaft 32 and the connecting rod is simple, reducing complex mechanical parts, reducing failure rate and maintenance costs. At the same time, this structure has high reliability and can maintain stable performance during a long production process. It is worth mentioning that compared with the generally used cylinder pushing method, the maximum speed of the cylinder pushing method is 300 pieces / minute, which means that after detecting defective products, the equipment needs to slow down to 300 pieces / minute for rejection, and then speed up production, which directly affects the production efficiency of the entire line. Through the cooperation of the eccentric shaft 32 and the connecting rod mechanism, the screening and classification mechanism 3 can achieve high-speed and large-displacement movement. This structure is simple and effective, so that the rejection speed can reach 1000 pieces / minute, which is more than three times the speed of the cylinder pushing solution. The structure has high-speed and stable characteristics. The production line does not need to slow down when rejecting defective products, and can maintain continuous high-speed operation, which greatly improves the overall production efficiency.

[0027] In this embodiment, it is further preferred that it further includes a guide rail 9 and a defective product storage device 10. The guide rail 9 is vertically and fixedly arranged below the mounting frame 6 and is located at the rear side of the base 11. The guide rail 9 is provided with a serpentine continuous winding guide channel. The upper end inlet of the guide channel is communicated with the defective product channel 4, and the lower end outlet of the guide channel faces the defective product storage device 10. This structure can ensure that after high-speed screening of defective products, they can still enter the storage area orderly, avoiding chaos and accumulation caused by high-speed rejection. Due to the guiding effect of the guide rail 9, the defective products enter the defective product storage device 10 in the same direction, reducing the risk of short circuit caused by the head and tail of the battery being connected, and ensuring the safety of defective product storage. Specifically, the defective product storage device 10 includes a belt conveyor and limit baffles. Three limit baffles are arranged in a U-shape on the belt conveyor. The guide rail 9 is located between the left and right limit baffles, and the outlet end of the guide rail 9 faces the belt conveyor. This layout helps the orderly arrangement and fixation of defective products, preventing the movement and chaos of defective products during storage. The orderly defective product processing flow improves the overall coordination of the production line, enabling each link of the production line to cooperate more smoothly and reducing production interruptions caused by improper handling of defective products.

[0028] During specific operation, when the equipment starts to operate, the battery is sent into the system through the feeding conveyor mechanism 1. This mechanism is responsible for longitudinally arranging the batteries along the conveyor belt and preparing them for the next material separation process. The arranged batteries reach the material separation positioning turntable 2. The turntable is driven by a motor and rotates intermittently, enabling the batteries to pass through the detection port of the visual detection device arranged on one side of the equipment one by one, thereby completing the quality inspection. According to the visual inspection results, qualified batteries are guided by the guide block 34 into the qualified product channel 5, while unqualified batteries are pushed into the defective product channel 4 by the pushing block 33. The defective product channel 4 guides the unqualified batteries to the guide rail 9 system. The guide rail 9 is designed in a serpentine shape to continuously wind and convey the defective products to the defective product storage device 10 in an orderly manner. During this process, when the battery rotates with the material separation positioning turntable 2, the pushing block 33 is in a standby state, ready to respond to the detection results. Once the visual detection device determines that a certain battery is unqualified, the pushing block 33 will receive a signal and be ready to perform the pushing action. Under the push of the pushing block 33, the unqualified battery is pushed away from the first traveling channel 7 to the defective product channel 4. This action is rapid and accurate, ensuring that defective products do not enter the subsequent production process.

For the specific structures, working principles, possible control methods, and spatial arrangement methods of these technical features, conventional selections in the art can be adopted and should not be regarded as the inventive points of this invention patent.
