Description

Technical Field

[0001] This invention relates to the field of toner cartridge manufacturing technology, and in particular to an automated toner cartridge sealing welding method. Background Technology

[0002] Existing toner cartridges generally have a seal welded on. This seal is used to separate the photosensitive drum and toner, preventing toner leakage during transportation. The seal also helps to identify whether the cartridge has been used. Currently, the seals are typically welded to the cartridge manually, involving pulling, cutting, and welding the seal. This requires multiple people, resulting in low efficiency and difficulty in guaranteeing the quality of the welded seal. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an automated method for welding toner cartridge seals, capable of automatically welding the seals.

[0004] An automated drum sealing welding method according to an embodiment of the present invention includes:

[0005] To install the toner cartridge, the toner cartridge is fixed to the welding base by hand or robotic arm.

[0006] The moving gripper moves the pulley assembly onto the first directional pulley. The first gripper moves with the pulley assembly and moves to a position slightly to the right of the end of the first directional track. At this position, the first gripper cannot clamp the first directional track.

[0007] The transport seal is transported by a feeding wheel, which transports the seal on the material wheel to the seal cutting mechanism. The feeding wheel continues to rotate, and the seal continues to move to the first directional track. After the infrared sensor at the end of the first directional track senses the seal groove, the feeding wheel is closed after a delay, so that part of the seal protrudes outside the first directional track, and the first gripper can just clamp the seal.

[0008] When cutting the seal, the first gripper starts working, clamping one end of the seal. The first gripper moves a small distance to the right, straightening the seal. The seal cutting mechanism then cuts the seal.

[0009] When welding the toner cartridge, the horizontal slide moves to the right, moving the seal to above the welding base. The first gripper and pulley assembly move downwards, moving the seal to the corresponding position. The welding power component drives the welding head to approach the welding base, welding the seal onto the welding base, thus completing the welding process.

[0010] In some embodiments, a detection step is further included, which is used to detect whether the seal of the seal feeding mechanism is broken.

[0011] In some embodiments, a seal detection mechanism is also included, comprising a swing arm hinged to the frame, a sensor mounted on the swing arm, and an alarm mounted below the hinge interface of the swing arm, the alarm sounding an alarm and shutting down the machine when it contacts the sensing wheel.

[0012] In some embodiments, the seal cutting mechanism includes a blade holder, a die mounted on the blade holder, a cutting blade slidably connected to the blade holder, and a second directional rail for mounting the book input end of the blade holder. The first directional rail is located at the output end of the blade holder, and the cutting blade can move closer to or further away from the die.

[0013] In some embodiments, a seal feeding mechanism is also included, which includes a material wheel and a plurality of feeding wheels. The material wheel and the feeding wheels are rotatably connected to the frame, and the plurality of feeding wheels drive the seals on the feeding wheels to move.

[0014] In some embodiments, the seal transfer mechanism includes a first directional track, a sliding bracket, a horizontal slide plate, a first gripper, and a pulley assembly. The first directional track is disposed at the output end of the seal cutting mechanism. The horizontal slide plate slides horizontally along the sliding bracket. The first gripper is installed on the horizontal slide plate at the end away from the seal cutting mechanism, and the pulley assembly is installed at the end close to the seal cutting mechanism. The pulley assembly and the first gripper can slide simultaneously in the vertical direction. The pulley assembly includes two clamping wheels, and both clamping wheels and the first gripper are used to clamp the seal on the first directional track.

[0015] In some embodiments, the toner cartridge welding mechanism includes a welding power component, a welding base, and a welding head. The welding base is used to fix the toner cartridge, and the welding power component drives the welding head to move closer to or away from the welding base.

[0016] In some embodiments, the toner cartridge welding mechanism further includes a conveyor belt and a plurality of welding bases, which are arranged sequentially along the conveyor belt transport direction.

[0017] In some embodiments, the pulley assembly further includes an elastic element, one end of which is connected to the movable clamping wheel and the other end of which is connected to the clamping plate. The elastic element drives the movable clamping wheel to approach the stationary clamping wheel.

[0018] In some embodiments, a second clamp is provided on the welding base for fixing the toner cartridge.

[0043] Reference Figures 1 to 7 The technical solution of the present invention is an automated toner cartridge sealing welding device, which includes: a frame 100, a sealing strip feeding mechanism 200 for transporting sealing strips, a sealing strip detection component 300 for detecting whether the sealing strip of the sealing strip feeding mechanism 200 is broken, a sealing strip cutting mechanism 400 for cutting the sealing strips, a sealing strip transfer mechanism 500, and a toner cartridge welding mechanism 600. The sealing strip transfer mechanism 500 includes a first directional track 510, a sliding bracket 520, a horizontal slide plate 530, a first gripper 540, and a pulley assembly 550. The first directional track 510 is disposed at the output end of the sealing strip cutting mechanism 400. The horizontal slide plate 530 slides horizontally along the sliding bracket 520. On the horizontal slide plate 530, the part away from the sealing strip cutting mechanism 400... A first gripper 540 is installed at one end, and a pulley assembly 550 is installed at the other end near the seal cutting mechanism 400. The pulley assembly 550 and the first gripper 540 can slide simultaneously in the vertical direction. The pulley assembly 550 includes two clamping wheels, and both clamping wheels and the first gripper 540 are used to clamp the seal on the first directional track 510. The drum welding mechanism 600 includes a welding power component 610, a welding base 620, and a welding head 630. The welding base 620 is used to fix the drum, and the welding power component 610 drives the welding head 630 to move closer to or away from the welding base 620. The seal feeding mechanism 200, the seal cutting mechanism 400, the seal transfer mechanism 500, and the drum welding mechanism 600 are sequentially installed on the frame 100.

[0044] The first gripper 540 is a double-headed electric gripper. When connected by electricity, the grippers on the double-headed electric gripper can come close to each other to fix one end of the seal.

[0045] Specifically, the pulley assembly 550 and the first gripper 540 move to the position of the first directional track 510. The seal transport mechanism transports the seal to the seal cutting mechanism 400, which then slides further onto the first directional track 510. The first gripper 540 fixes one end of the seal. The two clamping wheels on the pulley assembly 550 are located on the upper and lower sides of the first directional track 510, respectively. The two clamping wheels can approach each other and fix the other end of the seal. With both ends of the seal fixed, the seal remains stretched. The seal cutting mechanism 400 cuts the seal, and the horizontal slide plate 530 moves horizontally... The seal is moved above the welding base 620, and the first gripper 540 pulls the seal closer to the drum welding mechanism 600. The clamping wheel can roll along the first directional track 510 without wearing the seal. The pulley assembly 550 and the first gripper 540 can slide vertically at the same time, so that the seal is close to the drum of the welding base 620 and covers the drum. The welding power component 610 drives the welding head 630 to approach the welding base 620, so that the seal is fixed on the drum. The whole process does not require manual operation, reducing labor intensity, reducing production costs, and effectively improving processing quality.

[0046] In some embodiments, the seal feeding mechanism 200 includes a material wheel 210 and a plurality of feeding wheels 220. Both the material wheel 210 and the feeding wheels 220 are rotatably connected to the frame 100. The plurality of feeding wheels 220 drive the seals on the feeding wheels 220 to move. There are an even number of feeding wheels 220, which are evenly distributed on the upper and lower sides of the seal to clamp the seal. The feeding wheels 220 on the upper and lower sides rotate in opposite directions to maintain the transport direction of the seal.

[0047] Specifically, the seal feeding mechanism 200 also includes pressure rollers 230. There are four or more pressure rollers 230, which are symmetrically arranged on the upper and lower sides of the seal. The seal is transported between the pressure rollers 230, so that the seal can be output in a straight line.

[0048] Specifically, the feeding wheel 220 is provided with friction texture to increase the friction between the feeding wheel 220 and the seal, thus maintaining the smooth operation of the seal.

[0049] Specifically, the frame 100 is provided with multiple sliding holes, and multiple feeding wheels 220 are respectively installed on the corresponding sliding holes. The feeding wheels 220 can move on the sliding holes. By adjusting the position of the feeding wheels 220, seals of different thicknesses can be used.

[0050] In some embodiments, the seal detection mechanism includes a swing arm 310 hinged to the frame 100, a sensor 320 mounted on the swing arm 310, and an alarm 330 mounted below the hinge joint of the swing arm 310. The alarm 330 sounds an alarm and shuts down the machine when it contacts the sensor wheel. When the cable breaks or detaches from the machine, the swing arm 310 swings down naturally. When the sensor 320 contacts the alarm 330, it triggers a switch inside the alarm 330, disconnecting the main power supply to the machine, stopping its operation, and simultaneously connecting the backup power supply to activate the alarm bell to alert the operator. This reduces material waste and even prevents damage to the machine from cable entanglement. It also reduces employee workload, allowing them to perform other tasks after completing the initial preparation work, preventing the machine from continuing to operate after the seal breaks, which could lead to the inability to solder the toner cartridge.

[0051] In some embodiments, the seal cutting mechanism 400 includes a blade holder, a die mounted on the blade holder, a cutting blade slidably connected to the blade holder, and a second directional rail 410 mounted on the input end of the blade holder. The first directional rail 510 is located at the output end of the blade holder, allowing the cutting blade to move closer to or further away from the die. The cutting blade can cut the seal by moving closer to or further away from the die. The first directional rail 510 is located at the input end of the blade holder, and the second directional rail 410 is located at the output end. The directional rails are used to maintain the stability of the seal's input or output. The widths of both the first and second directional rails 510 are set according to the predetermined size of the seal to maintain the stability of the seal's input or output.

[0052] Specifically, both the first directional rail 510 and the second directional rail 410 can be detached to install the knife holder, and different sizes of seals can be used by changing the directional rail.

[0053] In some embodiments, an infrared sensor 320 is provided at the end of the first directional track 510. The infrared sensor 320 is electrically connected to the feeding wheel 220. When the seal is transported to the upper side of the first directional track 510, the infrared sensor 320 sends a signal to the feeding wheel 220, the feeding wheel 220 stops moving, and the seal stops transporting.

[0054] In some embodiments, the seal transfer mechanism 500 further includes a first power component and a second power component. The first power component drives the horizontal slide plate 530 to slide horizontally along the sliding bracket 520, and the second power component drives the pulley assembly 550 and the first gripper 540 to slide vertically simultaneously. Both the first and second power components are disposed on the side of the horizontal slide plate 530 opposite to the first gripper 540. The first gripper 540 and the pulley assembly 550 are disposed on one side of the horizontal slide plate 530, and the first and second power components are disposed on the other side of the horizontal slide plate 530 to prevent the first and second power components from interfering with the first gripper 540 and the pulley assembly 550 during transportation, thus affecting the transport of the seal.

[0055] Specifically, both the first and second power components are lead screws.

[0056] In some embodiments, the pulley assembly 550 includes a clamping plate 551, a movable clamping wheel 552, and a stationary clamping wheel 553. The stationary clamping wheel 553 is rotatably connected to the clamping plate 551, and the movable clamping wheel 552 can move closer to or away from the stationary clamping wheel 553. The clamping plate 551 is fixedly connected to the first gripper 540. The clamping wheels on the pulley assembly 550 need to clamp the upper and lower sides of the first directional track 510 respectively. The first directional track 510 itself has a certain thickness. After the pulley assembly 550 moves out of the first directional track 510, there is a certain gap between the clamping wheels. The movable clamping wheel 552 moves closer to the stationary clamping wheel 553, so that the two clamping wheels can clamp the seal, keeping both ends of the seal in a clamped state.

[0057] Specifically, both clamping wheels are damping wheels, which have a certain damping to prevent the clamping wheels from rolling naturally, causing the seal to loosen and affecting the quality of the seal.

[0058] In some embodiments, the pulley assembly 550 further includes an elastic element, one end of which is connected to a movable clamping wheel 552 and the other end to a clamping plate 551. The elastic element drives the movable clamping wheel 552 closer to the stationary clamping wheel 553. The elastic element brings the movable clamping wheel 552 closer to the stationary clamping wheel 553, keeping the two clamping wheels in a clamped state.

[0059] In some embodiments, a second gripper 621 is provided on the welding base 620, which is used to fix the toner cartridge. The second gripper 621 is a three-headed electric gripper, and the claws of the three-headed electric gripper can move closer to the center of the second gripper 621 to clamp the object. A triangular positioning block is provided at one end of the toner cartridge, and the second pointed claw quickly positions the toner cartridge, which facilitates the installation of the toner cartridge.

[0060] The specific welding base 620 is also equipped with a support block, which is used to support the other end of the toner cartridge and maintain the stability of the toner cartridge installation.

[0061] In some embodiments, the drum welding mechanism 600 further includes a conveyor belt 640 and a plurality of welding bases 620, which are arranged sequentially along the transport direction of the conveyor belt 640.

[0062] In some embodiments, the conveyor belt 640 is provided with a guide rod 641, and the welding base 620 is provided with a guide groove 622. The guide rod 641 cooperates with the guide groove 622. The cooperation between the guide rod 641 and the guide groove 622 maintains the stability of the welding base 620 in the horizontal direction, ensuring that the seal can be accurately attached to the corresponding position of the toner cartridge.

[0063] In some embodiments, the welding base 620 is provided with a position sensor 320. The position sensor 320 moves to a corresponding position with the power component that drives the first gripper 540 to move up and down. When the seal moves to the corresponding position, the first gripper 540 is controlled to stop moving.

[0064] The working principle of the automated toner cartridge sealing welding device is as follows: The toner cartridge is fixed on the welding base 620 by hand or robotic arm; the pulley assembly 550 moves to the first directional pulley, and the first gripper 540 moves with the pulley assembly 550. The first gripper 540 moves to a position slightly to the right of the end of the first directional track 510, at which position the first gripper 540 cannot clamp the first directional track 510; the feeding wheel 220 transports the seal on the material wheel 210 to the seal cutting mechanism 400. The feeding wheel 220 continues to rotate, and the seal continues to move to the first directional track 510. The infrared sensor 320 at the end of the first directional track 510 senses the seal groove. After the seal is removed, the feeding wheel 220 is closed after a delay, causing the seal to protrude beyond the first directional track 510, where the first gripper 540 can clamp the seal. The first gripper 540 then starts working, clamping one end of the seal. The first gripper 540 moves a short distance to the right, straightening the seal. The seal cutting mechanism 400 then cuts the seal. The horizontal slide plate 530 moves to the right, moving the seal above the welding base 620. The first gripper 540 and the pulley assembly 550 move downwards, moving the seal to the corresponding position. The welding power component 610 drives the welding head 630 to approach the welding base 620, welding the seal onto the welding base 620, thus completing the welding process.

[0065] This application can adapt to different types of toner cartridges. The embodiments in the accompanying drawings do not show the structure of the toner cartridge and the corresponding welding joint. The welding head is adapted to different types of toner cartridges by installing welding structures of different sizes.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effects, should be included within the scope of protection of this disclosure and fall under the protection scope of the present invention.
