A coin cell battery feeding device

Abstract

This utility model belongs to the field of button batteries, and in particular, it is a button battery feeding device. Addressing the problems of existing traditional vibratory feeder feeding mechanisms, such as batteries easily tipping over or stacking within the conveying track, lack of an effective screening mechanism when mixing batteries of different specifications, and the rigid feeding method driven by a vibratory motor easily causing damage to the battery surface coating, the following solution is proposed. It includes an L-shaped support plate, with side plates fixedly connected to both sides of the L-shaped support plate. A fixed inclined plate is fixedly connected to one side of the top of the L-shaped support plate. The fixed inclined plate is fixedly connected between the two side plates and is inclined. In this utility model, a double L-shaped rod dynamic adjustment mechanism is used. When the sliding feeding plate vibrates and displaces, the top of the pushing rod contacts the inclined surface of the trapezoidal hole, driving the two sliding L-shaped rods to form a 2mm gap compensation. The staggered fixed guide plates on the surface of the fixed inclined plate form a serpentine conveying channel, allowing for a longer screening time for the batteries.

Description

Technical Field

[0001] This utility model relates to the field of button battery technology, and in particular to a button battery feeding device. Background Technology

[0002] Background: In the button battery manufacturing industry, the feeding device is the core equipment in the front-end process, and its feeding stability and sorting accuracy directly affect the quality control of the subsequent packaging process.

[0003] Traditional vibratory feeder mechanisms have three major technical bottlenecks: First, batteries are prone to tipping over or stacking in the conveyor track, resulting in a jamming failure rate as high as 8%; second, there is a lack of effective screening mechanism when mixing batteries of different specifications, requiring manual secondary sorting, which reduces production efficiency by 30%; third, the rigid feeding method driven by the vibratory motor is prone to damage to the coating on the battery surface, and the pass rate can only be maintained at about 92%.

[0004] The aforementioned problems have led to a dual dilemma for battery manufacturers: high energy consumption and low yield, making it difficult to meet the stringent requirements of the consumer electronics market for micro batteries. Summary of the Invention

[0005] The purpose of this invention is to address three major technical bottlenecks in existing traditional vibratory feeder mechanisms: First, batteries are prone to tipping over or stacking within the conveyor track, resulting in a jamming failure rate as high as 8%; second, there is a lack of effective screening mechanisms when mixing batteries of different specifications, requiring manual secondary sorting, which reduces production efficiency by 30%; and third, the rigid feeding method driven by the vibratory motor is prone to damaging the battery surface coating, resulting in a pass rate of only about 92%. Therefore, this invention proposes a button battery feeding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A button battery feeding device includes an L-shaped support plate, with side plates fixedly connected to both sides of the L-shaped support plate and a fixed inclined plate fixedly connected to one side of the top of the L-shaped support plate. The fixed inclined plate is fixedly connected between the two side plates and is inclined. The top of the fixed inclined plate has multiple discharge holes for screening the size of the button batteries. Two fixed horizontal plates are fixedly connected between the two side plates, and a sliding feeding plate is slidably connected between the two side plates. The sliding feeding plate is located on one side of the fixed inclined plate and is used to transport the material at the top of the sliding feeding plate to the top of the fixed inclined plate. Two first compression springs are symmetrically arranged between the fixed horizontal plates and the sliding feeding plate. Both ends of the first compression springs abut against the bottom of the sliding feeding plate and the top of the fixed horizontal plates through spring seats. A current-diverting component for diverting the button battery is provided at the top of the sliding feeding plate.

[0007] In one possible design, the diversion assembly includes two fixed L-shaped rods symmetrically arranged at the top of the sliding feed plate, fixedly connected to the top of the two fixed L-shaped rods and a common top cover plate, one end of the top cover plate having an arc-shaped groove, two symmetrically arranged sliding L-shaped rods slidably connected between the top cover plate and the sliding feed plate, the two sliding L-shaped rods being located between the two fixed L-shaped rods, the gap between the sliding L-shaped rods and the fixed L-shaped rods being used for conveying button batteries, and a baffle plate being fixedly connected to one side of the top of the top cover plate.

[0008] In one possible design, a triangular guide block is fixedly connected at the midpoint between the upper cover plate and the sliding feed plate, and the plane of the triangular guide block abuts against one end of the sliding L-shaped rod.

[0009] In one possible design, a rectangular plate is fixedly connected to one side of the sliding L-shaped rod, and the same second compression spring is fixedly connected between the two rectangular plates. A trapezoidal hole is opened at the bottom center of the rectangular plate, and two symmetrically arranged rectangular holes are opened inside the sliding feeding plate. The rectangular holes and trapezoidal holes are matched. Two symmetrically arranged push rods are fixedly connected to the top of one of the fixed horizontal plates. The top of the push rods slides into the interior of the rectangular holes, and the top of the push rods is used in conjunction with the trapezoidal holes.

[0010] In one possible design, multiple fixed guide plates are fixedly connected to the top of the fixed inclined plate. The multiple fixed guide plates are arranged alternately, and the fixed guide plates are inclined to guide the button battery.

[0011] In one possible design, two symmetrically arranged support legs are fixedly connected to the bottom of the side plate, a first collection box is placed on one side of the bottom of the side plate to collect button batteries that cannot pass through the discharge hole, and a second collection box is placed directly below the side plate to collect button batteries that pass through the discharge hole.

[0012] In this application, during use, the button battery is placed on the top of the sliding feed plate from one side and begins to slide down along the inclined surface of the sliding feed plate. The baffle prevents the button battery from popping out, and the triangular guide block divides the button battery into two sides. At this time, the button battery is blocked by the arc groove and cannot be stacked up and down into the gap between the top cover plate and the sliding feed plate. It can only enter one by one between the sliding L-shaped rods and the fixed L-shaped rods on both sides. The arc surfaces of the sliding L-shaped rods and the fixed L-shaped rods facilitate the entry of the button battery. The vertical parts of the sliding L-shaped rods and the fixed L-shaped rods can facilitate the downward conveying of the button battery one after another, ensuring the subsequent screening effect. After the button batteries are conveyed downwards, they can slide down along the surface of the fixed inclined plate. The setting of multiple fixed guide plates can extend the movement path of the button batteries. Button batteries of appropriate size are discharged through the discharge hole and enter the interior of the second collection box. Larger button batteries slide down along the surface of the fixed inclined plate and enter the interior of the first collection box for collection, thus realizing the separation of two types of button batteries. Furthermore, during the continuous feeding process, the button battery causes the sliding feed plate to vibrate continuously in the vertical direction. The sliding feed plate compresses the first compression spring, allowing it to vibrate multiple times in the vertical direction. When the sliding feed plate moves downward, the top of the push rod moves from the inside of the rectangular hole to the inside of the trapezoidal hole. The top of the push rod abuts against the inclined surface of the inner wall of the top of the trapezoidal hole. At this time, the two rectangular plates move closer to each other, and the rectangular plates compress the second compression spring, thereby increasing the gap between the sliding L-shaped rod and the fixed L-shaped rod. This prevents the button battery from getting stuck in the gap between the sliding L-shaped rod and the fixed L-shaped rod, thus preventing material accumulation.

[0013] Beneficial effects: Utilizing a dual L-shaped rod dynamic adjustment mechanism, when the sliding feed plate experiences a 0.5mm vibration displacement, the top of the push rod contacts the inclined surface of the trapezoidal hole, driving the two sliding L-shaped rods to form a 2mm gap compensation. Actual measurements show that this mechanism can automatically remove jammed particles smaller than 1.5mm in diameter, reducing the number of stoppages due to jamming by 92% compared to traditional vibratory feeders. During battery transport, the 120° diversion angle design of the triangular guide block automatically distributes the battery flow into two streams, and combined with the 0.3mm height-limiting structure of the arc-shaped groove, effectively blocks the stacked material transport path, increasing the single-channel transport efficiency to 120 particles / minute. The staggered fixed guide plates on the surface of the inclined plate form a serpentine conveying channel with a length extending to 800mm, providing a stable screening time of 4.5 seconds for the batteries. The discharge port adopts a stepped aperture design; the upper section has a diameter of 5.2mm, forming a 0.2mm interference fit with the standard battery diameter, while the lower section has a diameter of 4.8mm, enabling automatic centering guidance and achieving a sorting accuracy of 99.5%. For oversized batteries, the 15° inclination angle of the fixed inclined plate, combined with the Teflon coating on the surface, ensures that large-sized batteries smoothly slide into the first collection box at a speed of 0.3m / s, avoiding impact damage. The dual compression spring system forms a three-stage buffer mechanism. The first compression spring, with a stiffness of 25 N / mm, absorbs vertical impacts, while the second compression spring, with a stiffness of 12 N / mm, enables horizontal adjustment, thus increasing the device's impact resistance by three times. The gap between the sliding feed plate and the fixed horizontal plate is dynamically adjustable within a range of 0.1-0.5 mm, ensuring efficient vibration transmission while avoiding mechanical interference. After 2000 hours of durability testing, the spring fatigue life exceeds 10^6 cycles, meeting the requirements of 24-hour continuous operation in battery production lines. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1 Reference Figure 1-4 A feeding device includes an L-shaped support plate 13, with side plates 1 fixedly connected to both sides of the L-shaped support plate 13. A fixed inclined plate 14 is fixedly connected to one side of the top of the L-shaped support plate 13. The fixed inclined plate 14 is fixedly connected between the two side plates 1 and is inclined. A plurality of discharge holes 15 are opened on the top of the fixed inclined plate 14. The discharge holes 15 are used to screen the size of the button batteries. Two fixed horizontal plates 9 are fixedly connected between the two side plates 1. A sliding feeding plate 11 is slidably connected between the two side plates 1. The sliding feeding plate 11 is located on one side of the fixed inclined plate 14 and is used to transport the material at the top of the sliding feeding plate 11 to the top of the fixed inclined plate 14. Two first compression springs 10 are symmetrically arranged between the fixed horizontal plates 9 and the sliding feeding plate 11. Both ends of the first compression springs 10 abut against the bottom of the sliding feeding plate 11 and the top of the fixed horizontal plates 9 through spring seats. A current-diverting assembly for diverting the button battery is provided at the top of the sliding feeding plate 11. The current-diverting assembly includes two fixed L-shaped rods 20 symmetrically arranged at the top of the sliding feeding plate 11. A top cover plate 7 is fixedly connected to the top of the two fixed L-shaped rods 20. An arc groove 5 is opened at one end of the top cover plate 7. Two sliding plates 5 are slidably connected between the top cover plate 7 and the sliding feeding plate 11. Two sliding L-shaped rods 21 are located between two fixed L-shaped rods 20. The gap between the sliding L-shaped rods 21 and the fixed L-shaped rods 20 is used to transport button batteries. A baffle 6 is fixedly connected to one side of the top of the upper cover plate 7. A triangular guide block 12 is fixedly connected to the middle position between the upper cover plate 7 and the sliding feed plate 11. The plane of the triangular guide block 12 abuts against one end of the sliding L-shaped rod 21. The button battery is put onto the top of the sliding feed plate 11 through one side and begins to slide down along the slope of the sliding feed plate 11. The baffle 6 prevents the button battery from popping out. The triangular guide block 12 divides the button battery into two sides. At this time, the button battery is blocked by the arc groove 5 and cannot be stacked up and down into the gap between the upper cover plate 7 and the sliding feed plate 11. It can only enter one by one between the sliding L-shaped rods 21 and the fixed L-shaped rods 20 on both sides. The arc surfaces of the sliding L-shaped rods 21 and the fixed L-shaped rods 20 facilitate the insertion of the button battery. The vertical parts of the sliding L-shaped rod 21 and the fixed L-shaped rod 20 can facilitate the downward conveying of button batteries one after another, ensuring the subsequent screening effect. A rectangular plate 22 is fixedly connected to one side of the sliding L-shaped rod 21. A second compression spring 19 is fixedly connected between the two rectangular plates 22. A trapezoidal hole 18 is opened at the bottom center of the rectangular plate 22. Two rectangular holes 17 are symmetrically arranged inside the sliding feed plate 11. The rectangular holes 17 and trapezoidal holes 18 are matched. Two push rods 16 are symmetrically arranged fixedly connected to the top of one of the fixed horizontal plates 9. The top of the push rods 16 slides into the interior of the rectangular holes 17. The top of the push rods 16 is matched with the trapezoidal holes 18. During the continuous feeding process, the button battery will drive the sliding feed plate 11. 1. The sliding feed plate 11 vibrates continuously in the vertical direction, squeezing the first compression spring 10. It can vibrate multiple times in the vertical direction. When the sliding feed plate 11 moves down, the top of the push rod 16 moves from the inside of the rectangular hole 17 to the inside of the trapezoidal hole 18. The top of the push rod 16 abuts against the inclined surface of the inner wall of the top of the trapezoidal hole 18. At this time, the two rectangular plates 22 approach each other, and the rectangular plates 22 squeeze the second compression spring 19. As a result, the gap between the sliding L-shaped rod 21 and the fixed L-shaped rod 20 increases, which prevents the button battery from getting stuck in the gap between the sliding L-shaped rod 21 and the fixed L-shaped rod 20, thereby preventing material accumulation.

Two symmetrically arranged support legs 4 are fixedly connected to the bottom of the side plate 1. A first collection box 2 is placed on one side of the bottom of the side plate 1 to collect button batteries that cannot pass through the discharge hole 15. A second collection box 3 is placed directly below the side plate 1 to collect button batteries that pass through the discharge hole 15. After the button batteries are conveyed downward, they can slide down the surface of the fixed inclined plate 14. The arrangement of multiple fixed guide plates 8 can extend the movement path of the button batteries. Button batteries of appropriate size are discharged through the discharge hole 15 and enter the interior of the second collection box 3. Larger button batteries slide down the surface of the fixed inclined plate 14 and enter the interior of the first collection box 2 to complete the collection, thereby realizing the separation of two types of button batteries.
