Description

Technical Field

[0001] This utility model relates to the field of printing consumables, and in particular to a sponge assembly machine for ink cartridges. Background Technology

[0002] In the field of printing consumables manufacturing, the assembly of the sponge inside the ink cartridge is a crucial process for ensuring ink dispensing stability and preventing ink leakage. The sponge must be precisely placed into the corresponding cavity of the ink cartridge, and the assembly process must avoid deformation or displacement of the sponge to ensure the subsequent performance of the ink cartridge. Currently, the industry mostly uses vibratory feeders to supply sponges for ink cartridges, utilizing the vibration force of the vibratory feeder to transport the sponges one by one to the assembly station. However, ink cartridge sponges are typically soft, low-density, and lightweight, presenting significant drawbacks in vibratory feeder processes. 1. Lightweight sponges tend to attract and stack each other under the high-frequency vibration of the vibratory feeder, making it difficult to achieve orderly separation and causing blockage of the feeding channel; 2. The sponge itself lacks sufficient gravity support, and it is easy to get stuck in the discharge port, guide chute, etc. of the vibratory plate during vibration, causing interruption of material supply and thus causing the whole machine to stop. Frequent jamming and shutdown not only require manual cleaning of the blocked sponge in time, increasing labor costs, but also seriously affect the production rhythm and reduce the overall production efficiency. At the same time, improper operation during manual cleaning may also damage or contaminate the sponge, affecting the product qualification rate. 3. The vibration intensity of the vibratory feeder is difficult to accurately match the lightweight sponge. Excessive intensity can easily cause the sponge to deform, while insufficient intensity cannot achieve effective material supply, further limiting its applicability in the ink cartridge sponge assembly process.

[0003] Therefore, there is an urgent need for an assembly equipment that can adapt to lightweight sponge feeding and avoid jamming and shutdown to solve the above problems. Utility Model Content

[0021] Reference Figures 1-3A sponge assembly machine for ink cartridges includes a frame 100 and a sponge feeding device 200, a vision recognition device 300, a feeding slide 400, a material transfer device 500, a conveyor line 600, and an assembly device 700 disposed on the frame 100. The sponge feeding device 200 includes a first linear drive assembly and a plurality of feeding plates 210, which are stacked sequentially in the vertical direction. The output end of the first linear drive assembly is connected to the feeding plate 210 located at the bottom, and the sponge is placed on the feeding plate 210. The visual recognition device 300 is disposed above the feeding plate 210 and is used to recognize the posture of the sponge on the feeding plate 210. The feeding chute 400 is located around the feeding plate 210; The material transfer device 500 is located above the feeding plate 210 and is used to transfer the sponge on the feeding plate 210 to the feeding chute 400 based on the feedback result of the visual recognition device 300. The conveyor line 600 is connected to the end of the feeding chute 400, and the ink cartridge is placed on the conveyor line 600; The assembly device 700 is connected between the feeding slide 400 and the conveyor line 600, and is used to assemble the sponge on the feeding slide 400 into the ink cartridge on the conveyor line 600.

[0022] Reference Figures 1-3 A sponge assembly machine for ink cartridges includes a frame 100 and a sponge feeding device 200, a vision recognition device 300, a feeding slide 400, a material transfer device 500, a conveyor line 600, and an assembly device 700, all mounted on the frame 100. The components work together to automate the entire process of sponge feeding and assembly into the ink cartridge. The specific working principle and implementation process are as follows: I. Sponge Supply Stage The sponge feeding device 200 adopts a multi-layer stacked feeding structure, with multiple feeding plates 210 stacked sequentially in the vertical direction. Each feeding plate 210 has a sponge to be assembled laid flat on it. Initially, all feeding plates 210 are stacked, and the sponge is stored between them. The first linear drive component (not shown in the figure) is connected to the bottom feeding plate 210. After the sponge on the top feeding plate 210 has been transferred, the first linear drive component starts and pushes the bottom feeding plate 210 upwards, driving all the sponge to move upwards. The stacked feeding plates 210 rise synchronously, causing the next feeding plate 210 to move to the same height as the initial feeding position, thus achieving continuous replenishment of the sponge. This feeding method does not rely on vibration force, avoiding the problems of adsorption and stacking of lightweight sponges caused by vibration, and ensuring a stable and orderly feeding process. It should be noted that after the sponge on the top feeding plate 210 has been transferred, the empty feeding plate 210 can be pushed away by the sixth linear drive component. This is existing technology and will not be described in detail here, nor should it be considered as a limitation of this utility model.

[0023] II. Sponge Posture Recognition and Transfer Stage Reference Figure 1 and Figure 2 Preferably, the material transfer device 500 includes a three-axis motion module 510, an angle adjustment component 520, and a clamping component 530; the angle adjustment component 520 is installed at the output end of the three-axis motion module 510; the clamping component 530 is installed at the output end of the angle adjustment component 520; the angle adjustment component 520 is used to adjust the angle of the clamping component 530 according to the feedback result of the vision recognition device 300, and the clamping component 530 is used to clamp the sponge on the feeding plate 210.

[0024] Specifically, the visual recognition device 300 is fixedly installed above the feeding plate 210, capturing real-time images of the sponge on the feeding plate 210. It analyzes the sponge's placement angle, position, and other posture information using image algorithms, and transmits this feedback result to the transfer device 500. The transfer device 500 achieves flexible movement in the X, Y, and Z directions through a three-axis motion module 510. Its output end is equipped with an angle adjustment component 520, which is preferably configured as a stepper motor. The angle adjustment component 520 can adjust according to the feedback signal from the visual recognition device 300. The rotation angle of the clamping component 530 is precisely adjusted. The clamping component 530 is preferably set as a thumb cylinder so that the clamping direction of the clamping component 530 is adapted to the posture of the sponge. Then, the three-axis motion module 510 drives the clamping component 530 to move to the target sponge position. The thumb cylinder is activated and gently clamps the sponge to avoid deformation or damage. After clamping, the three-axis motion module 510 moves the sponge to the entrance of the feeding slide 400. The clamping component 530 is released, and the sponge enters the feeding slide 400 under its own gravity and slides down the slide to the assembly station.

[0025] Furthermore, the bottom of the end of the feeding chute 400 has an opening, and a conveyor belt 900 is provided below the feeding chute 400. The lower end of the sponge can abut against the conveyor belt 900 at the opening, thereby ensuring that the sponge is conveyed forward until it reaches the end of the feeding chute 400, ensuring that it is accurately grasped by the assembly device 700.

[0026] III. Ink Cartridge Delivery and Positioning Stage Reference Figure 1 and Figure 3 In some embodiments, a first enclosure 810 is provided on one side of the conveyor line 600 and a second enclosure 820 is provided on the other side. An assembly channel 830 is formed between the first enclosure 810 and the second enclosure 820. The ink cartridge is placed in the assembly channel 830. The system also includes a fifth linear drive assembly 840 connected to the first enclosure 810. The fifth linear drive assembly 840 is used to adjust the distance between the first enclosure 810 and the second enclosure 820 to accommodate ink cartridges of different sizes.

[0027] In other embodiments, the frame 100 is provided with a control switch electrically connected to the fifth linear drive assembly 840. The control switch has a first position and a second position. When the control switch is in the first position, the fifth linear drive assembly 840 can drive the first enclosure 810 closer to the second enclosure 820, or when the control switch is in the second position, the fifth linear drive assembly 840 can drive the first enclosure 810 away from the second enclosure 820.

[0028] Specifically, the conveyor line 600 is connected to the end of the feeding chute 400. The ink cartridge to be assembled is placed in the assembly channel 830 of the conveyor line 600. The assembly channel 830 is constructed by the first enclosure plate 810 and the second enclosure plate 820 on both sides of the conveyor line 600. According to the size of the ink cartridge, the fifth linear drive assembly 840 can be adjusted by the control switch on the frame 100: when the control switch is in the first position, the fifth linear drive assembly 840 drives the first enclosure plate 810 closer to the second enclosure plate 820, reducing the distance of the assembly channel 830; when the control switch is in the second position, the fifth linear drive assembly 840 drives the first enclosure plate 810 away from the second enclosure plate 820, expanding the distance of the assembly channel 830, ensuring that the assembly channel 830 is accurately matched with the size of the ink cartridge and preventing the ink cartridge from shifting during the conveying process.

[0029] Reference Figure 1 and Figure 3In some embodiments, the positioning component 710 includes a third linear drive component 711, a fourth linear drive component 712, a first baffle 713, and a second baffle 714; the first baffle 713 is connected to the output end of the third linear drive component 711; the second baffle 714 is connected to the output end of the fourth linear drive component 712; the third linear drive component 711 and the fourth linear drive component 712 can respectively drive the first baffle 713 and the second baffle 714 to extend into the conveyor line 600, so that the ink cartridge is confined between the first baffle 713 and the second baffle 714, or the third linear drive component 711 and the fourth linear drive component 712 can respectively drive the first baffle 713 and the second baffle 714 to be pulled out from the conveyor line 600, so that the assembly conveyor line 600 drives the ink cartridge forward.

[0030] Specifically, when the ink cartridge moves along the conveyor line 600 to the corresponding assembly station of the assembly device 700, the positioning component 710 starts working: the third linear drive component 711 drives the first baffle 713 and the fourth linear drive component 712 drives the second baffle 714, which extend into the conveying path from both sides of the conveyor line 600, respectively, to limit the ink cartridge between the first baffle 713 and the second baffle 714, thereby achieving precise positioning of the ink cartridge and providing a stable assembly benchmark for subsequent sponge assembly; after the sponge assembly is completed, the third linear drive component 711 and the fourth linear drive component 712 respectively drive the first baffle 713 and the second baffle 714 to be pulled out from the conveyor line 600, releasing the limitation on the ink cartridge, and the conveyor line 600 continues to drive the assembled ink cartridge forward to enter the next production process.

[0031] IV. Sponge Assembly Stage Reference Figure 1 and Figure 3 In some embodiments, the assembly device 700 includes a positioning component 710, a rotary drive component 720, a second linear drive component 730, and a pin 740. The positioning component 710 is disposed on the conveyor line 600 and is used to position the ink cartridges on the conveyor line 600. The rotary drive component 720 has a first state and a second state. The second linear drive component 730 is mounted on the output end of the rotary drive component 720. The pin 740 is mounted on the output end of the second linear drive component 730. When the rotary drive component 720 is in the first state, it can drive the second linear drive component 730 closer to the feed chute 400 so that the second linear drive component 730 can insert the sponge on the feed chute 400. Alternatively, when the rotary drive component 720 is in the second state, it can drive the second linear drive component 730 closer to the conveyor line 600 so that the second linear drive component 730 can place the sponge into the ink cartridge on the conveyor line 600.

[0032] Specifically, the assembly device 700 is connected between the feeding slide 400 and the conveyor line 600. Its core is to realize the sponge picking and assembly through the state switching of the rotary drive component 720. The rotary drive component 720 is preferably set as a rotary cylinder. When the sponge slides down the feeding slide 400 to the designated position, the rotary drive component 720 switches to the first state, driving the second linear drive component 730 and the insertion pin 740 to rotate and approach the feeding slide 400. The second linear drive component 730 is preferably set as a linear cylinder. When the insertion pin 740 is aligned with the sponge, the second linear drive component 730 starts and pushes the insertion pin 740 forward. The insertion pin 740 inserts into the sponge to realize the stable insertion and picking of the sponge.

[0033] After material handling is completed, the second linear drive assembly 730 drives the pin 740 to reset, and the rotary drive assembly 720 switches to the second state, driving the second linear drive assembly 730 and the pin 740 to rotate in the direction of the conveyor line 600, so that the sponge is aligned with the assembly cavity of the positioned ink cartridge; then, the second linear drive assembly 730 starts again, pushing the pin 740 forward to smoothly place the sponge into the cavity of the ink cartridge, completing the assembly of the sponge and the ink cartridge. The structural design of the pin 740 is adapted to the soft characteristics of the sponge, avoiding damage to the sponge during insertion and placement, and ensuring assembly quality.

[0034] This utility model achieves full automation of the sponge feeding, posture recognition, transfer, ink cartridge positioning and assembly process through the structured cooperation of various components. It effectively solves the problem of easy jamming of lightweight sponge in traditional vibratory feeder feeding and ensures production continuity. At the same time, each drive component adopts a mature and universal mechanical structure, and the modular design makes the equipment easy to maintain. The adjustable assembly channel that adapts to different specifications of ink cartridges further expands the applicability of the equipment.

[0035] The advantages of this invention are: the sponge posture is accurately identified by the visual recognition device, and the material transfer device clamps and smoothly transfers the sponge, which solves the problem of material shortage in the feeding channel caused by the unstable feeding of the vibratory feeder, effectively avoids frequent shutdowns, ensures the continuity of the production process, and significantly improves production efficiency.

[0036] Of course, this utility model is not limited to the above-described embodiments.

All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
