Description

Technical Field

[0001] This invention relates to the field of button cell production equipment technology, specifically to an automated button cell production equipment. Background Technology

[0002] Button batteries, also known as coin cells, are batteries shaped like a small button. Due to their small size, button batteries are widely used in various microelectronic products, typically as backup power for devices such as computer motherboards, electronic watches, electronic dictionaries, electronic scales, memory cards, remote controls, electric toys, pacemakers, hearing aids, counters, and cameras. Button batteries are divided into two main categories: chemical batteries and physical batteries. Chemical batteries are the most common, consisting of an anode (positive electrode), a cathode (negative electrode), and an electrolyte. The casing of a button battery is made of stainless steel and includes a positive electrode cap. It is composed of a positive and negative electrode cap and an insulating sealing ring between the positive and negative electrode caps. The sealing ring is made of nylon and, in addition to its insulating function, also prevents electrolyte leakage. There are many types of button batteries, most of which are named after the materials used, such as silver oxide batteries, lithium batteries, and alkaline manganese batteries. However, due to the small size of button batteries, they are currently mostly produced using manual assembly line operations. Generally, each workstation is staffed with one employee. Button batteries require the addition of multiple layers of electrolyte, which must be done manually one by one. This production method is inefficient and requires skilled workers to ensure high product quality. The existing Chinese patent CN 207611828 U discloses an automated button cell battery production equipment. This automated button cell battery production equipment uses a first motor, the drive end of the first motor drives a first drive shaft to rotate, the first drive shaft drives a threaded shaft to rotate. Since the threaded shaft is threadedly connected to the rotating shaft, the threaded shaft drives the rotating shaft to rotate, and the rotating shaft drives the gear to rotate. Thus, the gear acts on the threaded rod. Since the connecting block is threadedly sleeved on the threaded rod, the rotation of the threaded rod drives the movement of the connecting block. However, this equipment has two threaded rods in a connecting plate, but only one of the threaded rods is driven to rotate by the gear at any given time. This can easily cause the connecting plate to be jammed by the non-rotating threaded rod when it moves, thus preventing normal movement. Summary of the Invention

[0003] The purpose of this invention is to provide an automated button cell production equipment to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated button cell battery production equipment, including a workbench, a conveyor belt on the top of the workbench, button cells on the top of the conveyor belt, and a liquid filling mechanism fixedly installed on the top of the workbench. The liquid dispensing mechanism includes a support cylinder, a limiting rod, and a servo motor. The bottom of the support cylinder is fixedly connected to the top of the worktable. A forward and reverse motor is fixedly installed on the inner wall of the support cylinder. A rotating shaft is fixedly installed at the output end of the forward and reverse motor. A turntable is fixedly installed at the top of the rotating shaft. A syringe is clamped to the inner wall of the turntable. The bottom of the servo motor is fixedly connected to the top of the worktable. A threaded rod is fixedly installed at the output end of the servo motor.

The limiting rod movably passes through the bottom of the lifting plate. An installation mechanism is fixedly installed on the inner wall of the turntable, and a blocking mechanism is fixedly installed inside the support cylinder.

[0005] According to the above technical solution, the installation mechanism includes a slide groove, a stop block, a buckle, and a connecting groove. The stop block is engaged in a groove on the turntable and is also engaged on the outer wall of the syringe. The slide groove is located inside the turntable, and a buckle is engaged in the inner wall of the slide groove. A slot is provided on the back of the stop block, and the buckle is engaged in the slot. A spring is fixedly installed on the back of the buckle, and the end of the spring facing the back is fixedly connected to the inner wall of the slide groove. The connecting groove is located at the top of the turntable and communicates with the slide groove. An L-shaped plate is engaged in the inner wall of the connecting groove, and the bottom end of the L-shaped plate is fixedly connected to the top of the buckle. The buckle is engaged in the bottom outer wall of the syringe, and the top of the buckle is fixedly connected to the top of the turntable.

[0006] According to the above technical solution, the blocking mechanism includes a first gear and a limiting groove. The limiting groove is located on the outer wall of the support cylinder. The inner wall of the first gear is fixedly connected to the outer wall of the rotating shaft. The first gear meshes with a second gear. A second threaded rod is fixedly installed on the inner wall of the second gear. The bottom end of the second threaded rod is rotatably connected to the bottom inner wall of the support cylinder through a bearing. A connecting plate is threadedly connected to the outer wall of the second threaded rod. A baffle is fixedly installed on the right outer wall of the connecting plate. The baffle is engaged in the limiting groove.

[0007] According to the above technical solution, a support leg is fixedly installed at the bottom of the workbench, a damper is fixedly installed on the inner wall of the support leg, a support foot is fixedly installed at the bottom of the damper, and the top of the support foot is snapped into the support leg.

[0008] According to the above technical solution, an anti-slip plate is fixedly installed at the bottom of the lifting plate, and the lower surface of the anti-slip plate contacts the top of the injection rod inside the syringe.

[0009] According to the above technical solution, the syringe is made of transparent plastic, and a magnifying glass is fixedly installed at the bottom of the turntable, with the magnifying glass facing the lower half of the syringe.

[0010] According to the above technical solution, the buckle is L-shaped, and a groove is provided at the bottom of the buckle. The length of the spring in its uncompressed state is the same as the depth of the groove.

[0011] According to the above technical solution, the number of teeth of the first gear is three times the number of teeth of the second gear, and the baffle is located on the front of the button battery.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In this invention, a servo motor drives a threaded rod to rotate, which in turn moves a lifting plate downward. The downward movement of the lifting plate squeezes the injection rod inside the syringe, injecting the electrolyte into the button cell, completing the first electrolyte addition. The servo motor then reverses to move the lifting plate upward, and the forward and reverse motors drive the rotating shaft to rotate, which in turn drives the turntable and the syringes on the turntable to rotate. This allows syringes containing other electrolytes to rotate to the bottom of the lifting plate. Finally, the servo motor rotates forward to perform a second injection, completing the injection of different electrolytes. 2. In this invention, by inserting the bottom end of a syringe filled with electrolyte into a buckle, pulling the L-shaped plate to move it, and then moving the locking block, the locking block retracts into the slide groove, locking the stop block into the groove on the turntable to limit the syringe. When the L-shaped plate is released, the spring pushes the locking block into the slot, thus fixing the stop block. 3. In this invention, a baffle is set to block the button cell batteries, preventing them from continuing to move forward due to inertia after the conveyor belt stops, thus preventing the addition of liquid. A forward and reverse motor drives a rotating shaft to rotate, which in turn drives a first gear to rotate, which in turn drives a second gear to rotate. The rotation of the second gear causes the connecting plate to move upward, which in turn causes the baffle to move upward, so that the baffle no longer blocks the button cell batteries. After the second addition of liquid is completed, the conveyor belt can be started to carry the button cell batteries away until the next button cell battery is added. Before adding liquid, the forward and reverse motor needs to reverse to reset the syringe to avoid incorrect addition sequence. When the forward and reverse motor reverses to reset the syringe, the baffle resets, which can block the next button cell battery. 4. This invention, by incorporating a transparent syringe and a magnifying glass, eliminates concerns about electrolyte corrosion of the syringe and allows direct observation of the remaining electrolyte level inside the syringe. The magnifying glass further enhances the worker's ability to monitor the electrolyte level. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0016] A preferred embodiment of the automated button cell production equipment provided by the present invention is as follows: Figures 1 to 7 As shown: An automated button cell battery production equipment includes a workbench 1, a conveyor belt 2 on the top of the workbench 1, button cells 5 on the top of the conveyor belt 2, and a liquid filling mechanism 6 fixedly installed on the top of the workbench 1. The liquid dispensing mechanism 6 includes a support cylinder 601, a limiting rod 607, and a servo motor 608. The bottom of the support cylinder 601 is fixedly connected to the top of the worktable 1. A forward and reverse motor 602 is fixedly installed on the inner wall of the support cylinder 601. A rotating shaft 603 is fixedly installed at the output end of the forward and reverse motor 602. A turntable 604 is fixedly installed on the top of the rotating shaft 603. A syringe 605 is clamped to the inner wall of the turntable 604. The forward and reverse motor 602 drives the rotating shaft 603 to rotate, thereby driving the turntable 604 and the rotating shaft 608 to rotate. The syringe 605 on the disc 604 rotates. The bottom of the servo motor 608 is fixedly connected to the top of the worktable 1. A threaded rod 609 is fixedly installed at the output end of the servo motor 608. A lifting plate 606 is threadedly connected to the outer wall of the threaded rod 609. The bottom of the limiting rod 607 is fixedly connected to the top of the worktable 1. The limiting rod 607 moves through the bottom of the lifting plate 606. An anti-slip plate 10 is fixedly installed at the bottom of the lifting plate 606. The lower surface of the anti-slip plate 10 is flush with the syringe 605. The top of the injection rod in syringe 5 is in contact with the anti-slip plate 10 to prevent slippage when the lifting plate 606 moves down to push the injection rod in syringe 605. A limit rod 607 is set so that when the servo motor 608 drives the first threaded rod 609 to rotate, the lifting plate 606 cannot rotate and can only move along the first threaded rod 609. The servo motor 608 is turned on to drive the first threaded rod 609 to rotate, which in turn drives the lifting plate 606 to move down. The lifting plate 606 moves down to squeeze the injection rod in syringe 605, injecting the electrolyte in syringe 605 into button battery 5, completing one liquid addition. Then the servo motor 608 is turned on to reverse, which makes the lifting plate 606 move up. Then the forward and reverse motor 602 is turned on to drive the rotating shaft 603 to rotate, which in turn drives the turntable 604 and the syringe 605 on the turntable 604 to rotate, so that the syringe 605 containing other electrolytes rotates to below the lifting plate 606. Then the servo motor 608 is turned on to rotate forward for a second injection, completing the injection of different electrolytes. An installation mechanism 7 is fixedly installed on the inner wall of the turntable 604, and a blocking mechanism 8 is fixedly installed inside the support cylinder 601. Example 2

[0017] Based on Example 1, a preferred embodiment of the automated button cell production equipment provided by the present invention is as follows: Figures 1 to 7As shown: The mounting mechanism 7 includes a slide groove 701, a stop block 702, a buckle 704, and a connecting groove 705. The stop block 702 is engaged in a groove on the turntable 604 and is also engaged on the outer wall of the syringe 605. The slide groove 701 is located inside the turntable 604, and a buckle 708 is engaged on the inner wall of the slide groove 701. A buckle groove 703 is provided on the back of the stop block 702, and the buckle 708 is engaged in the buckle groove 703. A spring 706 is fixedly installed on the back of the buckle 708, and the end of the spring 706 facing the back is connected to the slide groove 701. The inner wall of 1 is fixedly connected. The length of the spring 706 in its uncompressed state is the same as the depth of the slide groove 701, so that when the spring 706 is not subjected to external force, it can push the locking block 708 into the locking groove 703, so that the locking block 708 is locked in the locking groove 703. The blocking block 702 is fixed by the locking block 708 being locked in the locking groove 703. The connecting groove 705 is located at the top of the turntable 604 and is connected to the slide groove 701. An L-shaped plate 707 is engaged with the inner wall of the connecting groove 705, and the bottom end of the L-shaped plate 707 is connected to the locking block 701. The top of the 08 is fixedly connected. By pulling the L-shaped plate 707, the locking block 708 is moved, causing the locking block 708 to disengage from the slot 703, making it easy to remove the stop block 702. The buckle 704 is engaged with the bottom outer wall of the syringe 605. The top of the buckle 704 is fixedly connected to the top of the turntable 704. The buckle 704 is L-shaped, and the bottom of the buckle 704 has a groove, so that the buckle 704 can be well locked into the bottom of the syringe 605, providing upward support for the syringe 605, and cooperating with the stop block 702 to support the syringe. 605 is used to limit the movement of the syringe 605 during injection. The bottom end of the syringe 605 filled with electrolyte is inserted into the buckle 604. The L-shaped plate 707 is pulled to move, which in turn moves the locking block 708. The locking block 708 retracts into the slide groove 701 and squeezes the spring 706, locking the stop block 702 into the groove on the turntable 604 to limit the movement of the syringe 605. Then the L-shaped plate 707 is released, and the spring 706 changes force to push the locking block 708 into the slot 703, thus fixing the stop block 702. Example 3

[0018] Based on Example 1, a preferred embodiment of the automated button cell production equipment provided by the present invention is as follows: Figures 1 to 7As shown: The blocking mechanism 8 includes a first gear 801 and a limiting groove 806. The limiting groove 806 is located on the outer wall of the support cylinder 601. The inner wall of the first gear 801 is fixedly connected to the outer wall of the rotating shaft 603. The first gear 801 meshes with a second gear 803. A second threaded rod 802 is fixedly installed on the inner wall of the second gear 803. The bottom end of the second threaded rod 802 is rotatably connected to the bottom inner wall of the support cylinder 601 through a bearing. A connecting plate 805 is threadedly connected to the outer wall of the second threaded rod 802. The right outer wall of the connecting plate 805 is fixedly installed with... A baffle 804 is engaged within a limiting groove 806. The limiting groove 806 limits the baffle 804, thereby limiting the connecting plate 805. This ensures that when the second threaded rod 802 rotates, the connecting plate 805 can only move, not rotate. The number of teeth on the first gear 801 is three times the number of teeth on the second gear 803, so that for every one rotation of the first gear 801, the second gear 803 rotates three times. This increases the rotational speed of the second threaded rod 802 and improves the lifting distance of the connecting plate 805. The baffle 804 is located on the front of the button cell battery 5, allowing... The baffle 804 can block the button cell battery 5. When the output belt 2 transports the button cell battery 5 to the liquid filling position, the conveyor belt 2 stops. At this time, the front of the button cell battery 5 contacts the back of the baffle 804, preventing the button cell battery 5 from continuing to move forward due to inertia after the conveyor belt 2 stops, thus preventing liquid filling. After the first liquid filling is completed, the forward and reverse motor 602 drives the rotating shaft 603 to rotate, which in turn drives the turntable 604 and the syringe 605 on the turntable 604 to rotate for the next liquid filling. The rotating shaft 603 drives the first gear 801 to rotate, which in turn drives the second gear 805 to rotate. When gear 803 rotates, gear 803 drives connecting plate 805 to move upward, which in turn drives baffle 804 to move upward, so that baffle 804 no longer blocks button cell battery 5. After the second liquid addition is completed, conveyor belt 2 can be started to drive button cell battery 5 away until liquid is added to the next button cell battery 5. Before adding liquid, forward and reverse motor 602 needs to reverse to drive syringe 605 to reset to avoid incorrect liquid addition sequence. When forward and reverse motor 602 reverses to drive syringe 605 to reset, baffle 804 resets and can block the next button cell battery 5.

[0019] Furthermore, a support leg 4 is fixedly installed at the bottom of the worktable 1, a damper 9 is fixedly installed on the inner wall of the support leg 4, a support foot 3 is fixedly installed at the bottom of the damper 9, and the top of the support foot 3 is snapped into the support leg 4. The damper 9 is used to buffer and reduce the vibration generated by the forward and reverse motor 602 and the servo motor 608 on the worktable 1 when they are working.

[0020] Furthermore, the syringe 605 is made of transparent plastic, so there is no need to worry about the electrolyte corroding the syringe 605, and the remaining amount of electrolyte inside the syringe 605 can be directly observed. A magnifying glass 11 is fixedly installed at the bottom of the turntable 604, and the magnifying glass 11 is directly facing the lower half of the syringe 605. The magnifying glass 11 magnifies the syringe 605, making it easier for workers to observe the remaining amount of electrolyte inside the syringe 605.
