Description

Technical Field

[0002] Button batteries are named for their flat and small shape similar to buttons. They are widely used in various small electronic devices. Their main functions include timing function. In electronic watches, button batteries are mainly used to drive timing chips to realize the time display function; data storage function. In some electronic devices such as computer motherboards, button batteries are used to keep the CMOS setting information from being lost during power outages. This is mainly done by maintaining the data in RAM through continuous power supply; wireless transmission function. In devices such as remote controls and wireless mice, button batteries power the signal transmission module to ensure that the device can send signals to control other electrical appliances, especially in situations where miniaturized and lightweight power supplies are required, demonstrating their irreplaceable value.

[0003] Button batteries have a wide range of uses. To meet their usage requirements, the production equipment for button batteries needs to ensure production efficiency. In the current production process of button batteries, seven types of parts, namely, negative electrode shell, negative electrode sheet, diaphragm, positive electrode sheet, gasket, spring and positive electrode shell, are placed in the same vertical column on the tray in sequence. The parts are sucked up by seven negative pressure suction cups and moved to the assembly position synchronously. Since the negative pressure states of multiple negative pressure suction cups need to be individually controlled at the assembly position to achieve material discharge, each negative pressure suction cup needs to be connected to a negative pressure pipeline and a control valve. The pipeline system is complicated, and the suction force of multiple negative pressure suction cups cannot be guaranteed to be consistent, which may cause some parts to be sucked up while others are not, resulting in missing parts assembly and affecting the yield rate. Summary of the invention

[0004] The purpose of the present invention is to provide a button battery production line liquid injection fixture and a method of using the same in order to solve the above-mentioned problems. The present invention can maintain the suction of multiple groups of suction cup fixtures consistent, and keep multiple suction cup fixtures synchronously sucking up multiple assembly parts, thereby simplifying the equipment structure.

[0012] Preferably, a C-shaped support plate extending upward is fixed to the outer side of the fixed plate, and a movable disk and a fixed disk distributed overlappingly are provided on the inner side of the support plate. The movable disk is provided on the top side of the fixed disk, and a conversion motor fixed to the top side of the support plate is provided above the movable disk, and the output end of the conversion motor is fixedly connected to the movable disk.

[0014] Preferably, the fixed plate is provided with a vertically penetrating lower assembly hole corresponding to the upper assembly hole, and the lower assembly hole is tightly connected with the assembly head. The fixed plate is provided with a vertically penetrating lower discharge hole corresponding to the upper discharge hole. The upper discharge hole and the lower discharge hole have the same diameter and are both larger than the inner diameter of the assembly head. A collecting barrel is provided above the support plate, and the collecting barrel is connected with the mounting hole.

[0015] Preferably, a plurality of longitudinally extending rollers are rotatably arranged inside the conveyor below the pallet, a conveyor belt is arranged inside the conveyor, two conveyor rollers supporting the rotation of the conveyor belt are arranged inside the conveyor, a conveying motor driving the conveyor rollers to rotate is fixed on the front side of the conveyor, supports are transversely fixed at the four corners of the bottom of the conveyor, the bottom sides of the two groups of supports on the same side are longitudinally connected with supporting beams, the ends of the supporting beams are vertically penetrated by supporting feet, and the outer sides of the supporting feet are threaded with limiting nuts that are pressed against the bottom side of the supporting beams.

[0016] The method for using the liquid injection fixture of the button battery production line comprises the following steps:

[0017] a. Stack the negative electrode shells of button batteries vertically into the collecting barrel, and place the six assembly parts, namely, negative electrode sheet, diaphragm, positive electrode sheet, gasket, spring and positive electrode shell, into multiple receiving slots in the same vertical column on the tray from back to front in the assembly order, and connect the front end of the synchronous tube with the external negative pressure extraction equipment, use the conveyor to move the tray horizontally to the bottom of the multiple suction cup fixtures under the mounting frame, and use the lifting cylinder to support the slide rail to drive the synchronous tube to move downward, and place multiple suction cup fixtures into multiple groups of receiving slots accordingly, so as to synchronously maintain the negative pressure state of multiple suction cup fixtures through the synchronous tube, so as to synchronously suck up multiple assembly parts;

[0018] b. When one of the suction cup fixtures does not press against the assembly parts, the assembly parts at that position cannot close the bottom of the suction cup fixture, causing the suction channel inside the suction cup fixture at that position to be unable to be closed. Since multiple suction cup fixtures are connected to the synchronous tube, when one group of assembly parts is not sucked up, a negative pressure environment cannot be formed in the entire synchronous tube, and the suction cup fixtures at other positions can also remain detached from the assembly parts, thereby avoiding the loss of some parts during the assembly process;

[0019] c. During assembly, the movable plate is rotated by the conversion motor, and the upper assembly hole of the movable plate is rotated to the position of the mounting hole connected to the support plate. At this time, the bottom of the collection barrel is connected to the upper assembly hole, and the negative electrode shell in the collection barrel falls downward into the upper assembly hole. Then the conversion motor drives the movable plate to reset, and a group of negative electrode shells are rotated to the assembly head position using the upper assembly hole. At the same time, the movable plate closes the bottom of the collection barrel again, and the negative electrode shell falls along the lower assembly hole into the top side of the pressing block in the assembly head, completing the negative electrode shell unloading action;

[0020] d. When assembling other parts into the negative electrode shell, the driving assembly is used to support the synchronous tube to slide longitudinally backward under the support of the slide rail. When the last group of suction cup fixtures follows the synchronous tube to move above the assembly head, the top cylinder is used to support the synchronous tube to move downward, and the suction cup fixture is used to send the parts into the negative pressure shell in the assembly head along the upper assembly hole and the lower assembly hole. Then, the adjustment cylinder is used to drive the adjustment frame to move forward as a whole, so as to support the piston plate to move forward to between the last group of suction cup fixtures and its adjacent suction cup fixtures through the push rod, and the negative pressure connection state of the group of suction cup fixtures located directly above the assembly head and its adjacent suction cup fixtures is disconnected through the piston plate. At this time, the group of suction cup fixtures directly above the assembly head is released from the negative pressure state, and the adsorbed parts fall downward along the upper assembly hole and the lower assembly hole in turn into the negative electrode shell in the assembly head;

[0021] e. After that, the cylinder support adjustment frame is reset, and at the same time, the synchronous tube continues to translate backward synchronously under the support of the driving assembly to the position where the next set of suction cup fixtures are aligned with the assembly head and the parts are sent downward into the assembly head. Then, the cylinder support adjustment frame continues to slide forward until the piston plate moves between the suction cup fixture to be unloaded and the adjacent suction cup fixture in front of it, so that the negative pressure state of the suction cup fixture directly above the assembly head is released by the piston plate again, and the continuous unloading action of multiple suction cup fixtures sliding backward one by one is realized;

[0022] f. After the parts adsorbed by the multiple suction cup fixtures are poured into the assembly head, the movable plate is rotated by the conversion motor to close the top opening of the lower assembly hole of the fixed plate with the movable plate, and then the button battery parts in the stacked state are supported by the pressing block at the bottom cylinder to move upward, so that the button battery is pressed upward to the bottom side of the movable plate with the pressing block, so as to realize the pressing and sealing of the positive electrode shell and the negative electrode shell of the button battery;

[0023] g. After the assembly is completed, move the pressing block downward to place the button battery product into the assembly head, and rotate the movable plate to align the upper discharge hole with the lower assembly hole. At this time, lift the button battery product into the upper discharge hole, and rotate the movable plate at the same time to use the upper discharge hole to support the button battery product to rotate to the corresponding lower discharge hole position, and discharge the button battery downward through the lower discharge hole to complete the automatic assembly process of a group of button batteries.

[0024] The beneficial effects are as follows: 1. The present invention arranges multiple groups of suction cup fixtures and connects them to the same synchronous pipe, and uses the external negative pressure device of the synchronous pipe to provide suction negative pressure, so as to keep the suction forces of the multiple groups of suction cup fixtures consistent, keep the multiple suction cup fixtures to synchronously suck up multiple assembly parts, avoid the problem of missing parts caused by the negative pressure supplied by multiple fixtures separately, and simplify the equipment structure;

[0025] 2. At the same time, a piston plate extending into the synchronous tube is arranged at the bottom side of the slide rail. The position of the piston plate is controlled to individually adjust the working state of the suction cup fixture moved to the position above the assembly head. After the suction cup fixture moves to the assembly head position, it can be individually controlled to release the negative pressure state, thereby ensuring that other groups of suction cup fixtures in front maintain the adsorption state of subsequent assembly parts while realizing independent unloading. There is no need to set up additional negative pressure pipelines and control valves, which is more convenient to operate, reduces equipment failure rate, and improves working speed;

[0026] 3. In addition, a collecting barrel is provided as a negative electrode shell accommodating container for vertical feeding, which can cooperate with a rotatable movable plate to supply the negative electrode shell to the inside of the assembly head along the lower assembly hole of the fixed plate, thereby improving the convenience of feeding. There is no need to place the negative electrode shell in the tray accordingly, which is easy to use. At the same time, the movable plate can cooperate with the pressing block to press and assemble the button battery, without the need to set up additional pressing equipment, further simplifying the equipment structure and improving the yield rate and production efficiency.

A fixed plate 10 supporting the assembly head 11 is fixed on the rear side of the conveyor 1. The fixed plate 10 is a right-angle bent structure with the top extending backward. A bottom cylinder 12 is fixed on the bottom side of the fixed plate 10. The assembly head 11 is a vertically extending cylindrical structure. The telescopic end of the bottom cylinder 12 extends into the interior of the assembly head 11, and a pressure block 12a with a clearance fit on the inner wall of the assembly head 11 is fixed at the telescopic end of the bottom cylinder 12. The pressure block 12a can be lifted and lowered under the support of the bottom cylinder 12, and can support the button battery parts placed in the interior of the assembly head 11 to meet the requirements of loading and unloading and pressing.

[0047] A C-shaped support plate 13 extending upward is fixed on the outside of the fixed plate 10, and a movable disk 14 and a fixed disk 15 distributed in an overlapping manner are arranged on the inner side of the support plate 13. The movable disk 14 is arranged on the top side of the fixed disk 15, and the fixed disk 15 is coaxially distributed with the movable disk 14. A conversion motor 14c fixed to the top side of the support plate 13 is arranged above the movable disk 14, and the output end of the conversion motor 14c is fixedly connected to the movable disk 14, and the conversion motor 14c is used to drive the movable disk 14 to rotate.

The pallet 2 is fed into the top side of the rollers 101 via the conveyor belt 18, and the rollers 101 are used instead of the conveyor belt 18 to support the pallet 2, thereby improving the stability of the suction cup clamp 602 when it is pressed down against the top surface of the parts inside the pallet 2, which helps to improve the stability of the parts adsorption.

The outer threads of the support legs 104 are equipped with limit nuts 105 that are pressed against the bottom sides of the support beams 103. By adjusting the height position of the limit nuts 105 on the outer sides of the support legs 104, the ground flatness requirements of different installation positions can be met.

[0050] The method for using the liquid injection fixture of the button battery production line includes the following steps:

[0051] a. Stack the negative electrode shells of button batteries vertically into the collecting barrel 9, and place the six assembly parts of the negative electrode sheet, diaphragm, positive electrode sheet, gasket, spring and positive electrode shell to which the electrolyte is dripped into the multiple receiving grooves 201 in the same vertical column on the tray 2 from back to front in the assembly order, and connect the front end of the synchronous pipe 6 with the external negative pressure extraction device, use the conveyor 1 to move the tray 2 horizontally to the bottom of the multiple suction cup fixtures 602 under the mounting frame 4, and use the lifting cylinder to support the slide rail 5 to drive the synchronous pipe 6 to move downward, and place the multiple suction cup fixtures 602 into the multiple groups of receiving grooves 201 accordingly, so as to synchronously maintain the negative pressure state of the multiple suction cup fixtures 602 through the synchronous pipe 6, so as to synchronously suck up the multiple assembly parts;

[0052] b. When one of the suction cup fixtures 602 is not pressed against the assembly part, the assembly part at this position cannot close the bottom of the suction cup fixture 602, causing the suction channel inside the suction cup fixture 602 at this position to be unable to be closed. Since multiple suction cup fixtures 602 are connected to the synchronous tube 6, when one group of assembly parts is not sucked up, a negative pressure environment cannot be formed in the entire synchronous tube 6, and the suction cup fixtures 602 at other positions can also remain detached from the assembly parts, thereby avoiding the loss of some parts during the assembly process;

[0053] c. During assembly, the movable disk 14 is rotated by the conversion motor 14c, and the upper assembly hole 14a of the movable disk 14 is rotated to the position of the mounting hole 13a connected to the support plate 13. At this time, the bottom of the collecting barrel 9 is connected to the upper assembly hole 14a, and the negative electrode shell in the collecting barrel 9 falls downward into the upper assembly hole 14a. Then, the conversion motor 14c drives the movable disk 14 to reset, and a group of negative electrode shells are rotated to the position of the assembly head 11 by using the upper assembly hole 14a. At the same time, the movable disk 14 closes the bottom of the collecting barrel 9 again, and the negative electrode shell falls along the lower assembly hole 15a into the top side of the pressing block 12a in the assembly head 11, completing the negative electrode shell unloading action;

[0054] d. When assembling other parts into the negative electrode shell, the driving assembly 7 is used to support the synchronous tube 6 to slide longitudinally backward under the support of the slide rail 5. When the last set of suction cup fixtures 602 follows the synchronous tube 6 to move above the assembly head 11, the synchronous tube 6 is supported to move downward by the top cylinder 401, and the suction cup fixture 602 is used to send the parts along the upper assembly hole 14a and the lower assembly hole 15a into the negative pressure shell in the assembly head 11. Then, the adjusting cylinder 502 is used to drive the adjusting frame 8 to move forward as a whole, so as to pass through the push rod 8 02 The support piston plate 803 moves forward to between the last group of suction cup fixtures 602 and its adjacent suction cup fixtures 602, and the negative pressure connection state between the group of suction cup fixtures 602 located directly above the assembly head 11 and its adjacent suction cup fixtures 602 is disconnected through the piston plate 803. At this time, the group of suction cup fixtures 602 directly above the assembly head 11 is released from the negative pressure state, and the parts adsorbed by them fall downward along the upper assembly hole 14a and the lower assembly hole 15a in turn into the negative electrode shell in the assembly head 11;

[0055] e. After that, the adjusting cylinder 502 supports the adjusting frame 8 to reset, and at the same time, the synchronous tube 6 continues to translate backward synchronously under the support of the driving assembly 7 to the position where the next group of suction cup fixtures 602 are aligned with the assembly head 11 and the parts are sent downward into the assembly head 11, and then the adjusting cylinder 502 is used to support the adjusting frame 8 to continue to slide forward until the piston plate 803 moves between the suction cup fixture 602 to be unloaded and the adjacent suction cup fixture 602 in front of it, so that the negative pressure state of the suction cup fixture 602 directly above the assembly head 11 is released by the piston plate 803 again, and the continuous unloading action of multiple suction cup fixtures 602 sliding backward one by one is realized. After the unloading of the negative electrode sheet to which the electrolyte is dripped is completed, the electrolyte is dripped onto the negative electrode sheet placed in the assembly head 11;

[0056] f. After the parts sucked by the multiple suction cup fixtures 602 are poured into the assembly head 11, the movable plate 14 is rotated by the conversion motor 14c to close the top of the lower assembly hole 15a of the fixed plate 15 by the movable plate 14, and then the bottom cylinder 12 is used to support the pressing block 12a to support the stacked button battery parts to move upward, so that the button battery is pressed upward to the bottom side of the movable plate 14 by the pressing block 12a, so as to achieve the pressing and sealing of the positive electrode shell and the negative electrode shell of the button battery;

[0057] g. After the assembly is completed, the pressing block 12a is moved downward to place the button battery product into the assembly head 11, and the movable disk 14 is rotated to align the upper discharge hole 14b with the lower assembly hole 15a. At this time, the button battery product is lifted up into the upper discharge hole 14b, and the movable disk 14 is rotated at the same time to use the upper discharge hole 14b to support the button battery product to rotate to the corresponding lower discharge hole 15b position, and the button battery is discharged downward through the lower discharge hole 15b, completing the automatic assembly process of a group of button batteries.

[0058] Multiple groups of suction cup fixtures 602 are arranged and connected to the same synchronous pipe 6, and negative pressure is provided by the external negative pressure device of the synchronous pipe 6, so as to keep the suction force of the multiple groups of suction cup fixtures 602 consistent, and keep the multiple suction cup fixtures 602 to synchronously suck up multiple assembly parts, so as to avoid the problem of missing parts caused by the negative pressure supplied by multiple fixtures separately, and simplify the equipment structure;

[0059] At the same time, a piston plate 803 extending into the synchronization tube 6 is provided at the bottom side of the slide rail 5, and the position of the piston plate 803 is controlled to individually adjust the working state of the suction cup fixture 602 moved to the position above the assembly head 11. After the suction cup fixture 602 moves to the position of the assembly head 11, it can be individually controlled to release the negative pressure state, thereby ensuring that other groups of suction cup fixtures 602 in front maintain the adsorption state of subsequent assembly parts while realizing independent unloading, without the need to set up additional negative pressure pipelines and control valves, which is more convenient to operate, reduces equipment failure rate, and improves working speed;

[0060] In addition, a collecting barrel 9 is provided as a negative electrode shell accommodating container for vertical feeding, which can cooperate with a rotatable movable plate 14 to supply the negative electrode shell to the inside of the assembly head 11 along the lower assembly hole 15a of the fixed plate 15, thereby improving the convenience of feeding. There is no need to place the negative electrode shell in the tray 2 accordingly, which is easy to use. At the same time, the movable plate 14 can cooperate with the pressing block 12a to press and assemble the button battery, without the need to set up additional pressing equipment, further simplifying the equipment structure and improving the yield rate and production efficiency.

A method for using a liquid injection fixture for a button battery production line, using the liquid injection fixture for a button battery production line according to claim 9, characterized in that: The following steps are involved: a. stacking the negative electrode shells of the button batteries vertically into a collecting barrel (9), and placing the six assembly parts, namely, the negative electrode sheet, the diaphragm, the positive electrode sheet, the gasket, the spring, and the positive electrode shell, in a sequential order from back to front into a plurality of receiving grooves (201) in the same vertical row on the tray (2), and connecting the front end of the synchronous tube (6) to an external negative pressure extraction device, using a conveyor (1) to move the tray (2) horizontally to below a plurality of suction cup fixtures (602) below the mounting frame (4), and using a lifting cylinder to support the slide rail (5) to drive the synchronous tube (6) to move downward, and placing the plurality of suction cup fixtures (602) into the plurality of groups of receiving grooves (201) accordingly, so as to synchronously maintain the negative pressure state of the plurality of suction cup fixtures (602) through the synchronous tube (6), so as to synchronously suck up the plurality of assembly parts; b. When one of the suction cup fixtures (602) is not pressed against the assembly part, the assembly part at that position cannot close the bottom of the suction cup fixture (602), causing the suction channel inside the suction cup fixture (602) at that position to be unable to be closed. Since the plurality of suction cup fixtures (602) are all connected to the synchronous tube (6), when one group of assembly parts is not sucked up, a negative pressure environment cannot be formed in the entire synchronous tube (6), and the suction cup fixtures (602) at other positions can also remain detached from the assembly parts, thereby avoiding the loss of some parts during the assembly process; c. During assembly, the movable disk (14) is rotated by the conversion motor (14c), and the upper assembly hole (14a) of the movable disk (14) is rotated to the position of the mounting hole (13a) connected to the support plate (13). At this time, the bottom of the collection barrel (9) is connected to the upper assembly hole (14a), and the negative electrode shell in the collection barrel (9) falls downward into the upper assembly hole (14a). Then, the conversion motor (14c) drives the movable disk (14) to reset, and a group of negative electrode shells are rotated to the position of the assembly head (11) by using the upper assembly hole (14a). At the same time, the movable disk (14) closes the bottom of the collection barrel (9) again, and the negative electrode shell falls along the lower assembly hole (15a) into the top side of the pressing block (12a) in the assembly head (11), completing the negative electrode shell unloading action; d. When assembling other parts into the negative electrode shell, the driving assembly (7) is used to support the synchronous tube (6) to slide longitudinally backward under the support of the slide rail (5). When the rearmost set of suction cup fixtures (602) follows the synchronous tube (6) to move above the assembly head (11), the synchronous tube (6) is supported to move downward by the top cylinder (401), and the suction cup fixture (602) is used to send the parts along the upper assembly hole (14a) and the lower assembly hole (15a) into the negative pressure shell in the assembly head (11). Then, the adjusting cylinder (502) is used to drive the adjusting frame (8) to move forward as a whole, so as to pass through the push rod The support piston plate (802) moves forward to between the last group of suction cup clamps (602) and its adjacent suction cup clamps (602), and disconnects the negative pressure connection state between the group of suction cup clamps (602) located directly above the assembly head (11) and its adjacent suction cup clamps (602) through the piston plate (803). At this time, the group of suction cup clamps (602) directly above the assembly head (11) is released from the negative pressure state, and the parts adsorbed by them fall downward along the upper assembly hole (14a) and the lower assembly hole (15a) in sequence into the negative electrode shell in the assembly head (11); e. After that, the adjusting cylinder (502) supports the adjusting frame (8) to reset, and at the same time, the synchronous tube (6) is synchronously and continuously translated backward under the support of the driving assembly (7) to the position where the next set of suction cup fixtures (602) are aligned with the assembly head (11) and the parts are sent downward into the assembly head (11). Then, the adjusting cylinder (502) is used to support the adjusting frame (8) to continue to slide forward until the piston plate (803) moves between the suction cup fixture (602) to be unloaded and the suction cup fixture (602) adjacent to the front side thereof, so that the negative pressure state of the suction cup fixture (602) directly above the assembly head (11) is released by the piston plate (803) again, thereby realizing the continuous unloading action of sliding the multiple suction cup fixtures (602) backward one by one; f. After the parts sucked by the plurality of suction cup fixtures (602) are poured into the assembly head (11), the movable disk (14) is rotated by the conversion motor (14c) so as to use the movable disk (14) to seal the top opening of the lower assembly hole (15a) of the fixed disk (15), and then the bottom cylinder (12) is used to support the pressing block (12a) to support the stacked button battery parts to move upward, so as to use the pressing block (12a) to press the button battery as a whole upward to the bottom side of the movable disk (14), so as to achieve the compression sealing of the positive electrode shell and the negative electrode shell of the button battery; g. After the assembly is completed, the pressing block (12a) is moved downward to place the button battery product into the assembly head (11), and the movable disk (14) is rotated to align the upper discharge hole (14b) with the lower assembly hole (15a). At this time, the button battery product is lifted up into the upper discharge hole (14b), and the movable disk (14) is rotated at the same time to support the button battery product with the upper discharge hole (14b) to rotate to the position corresponding to the lower discharge hole (15b), and the button battery is discharged downward through the lower discharge hole (15b), thereby completing the automatic assembly process of a group of button batteries.
