[0002] The toner cartridge bin is usually called a toner cartridge or an ink cartridge, and is a container for loading toner in a laser printer. During the assembly process of the toner cartridge, its end cover needs to be preliminarily combined with the toner cartridge first, and then the two are completely pressed and fixed by an ultrasonic pressing device. Whether it is manual operation or automated conveying and pressing method, before pressing the end cover, the end cover and the toner cartridge need to be pre-combined first. However, in actual operation, there may be situations where the end cover and the toner cartridge are not fully engaged, or the edge of the end cover is not fully inserted into the toner cartridge, resulting in defective products after pressing and causing losses of materials and costs. To avoid the occurrence of the above problems, it is often necessary to manually adjust the position of the end cover repeatedly to ensure its correct installation before pressing. This method is not only time-consuming and laborious, but also inefficient. Summary of the Invention

Detailed implementation mode

[0025] Example 1: Refer to Figures 1 - 4, A toner cartridge end - cover pressing device, including a workbench 1. A gantry 2 is connected to the workbench 1. An ultrasonic plastic welder 3 is installed on the top of the gantry 2. A positioning mechanism for adjusting the alignment between the end - cover 11 and the toner cartridge 10 is provided on the gantry 2. The positioning mechanism includes two electric slide rails 43 respectively connected to the front and rear sides of the gantry 2. Lifting plates 42 are connected to the sliders of the two electric slide rails 43. Guide rails 41 are connected to the front and rear sides of the gantry 2. The guide rails 41 are located to the left of the electric slide rails 43. The two lifting plates 42 are respectively slidably connected to the two guide rails 41. The lifting of the lifting plates 42 is guided by the guide rails 41 to ensure that the lifting plates 42 lift more smoothly. A cylinder 44 is installed on the lifting plate 42. A mounting plate 45 is connected to the telescopic rod of the cylinder 44. Two left - right T - shaped sliding rods 46 are slidably connected to the mounting plate 45. A guide rod 47 is connected between the two left - right T - shaped sliding rods 46. The guide rod 47 includes a square plate connected to the two left - right T - shaped sliding rods 46 and two T - shaped rods respectively connected to the left and right sides of the square plate. Pushing plates 48 are slidably provided on the two T - shaped rods of the guide rod 47. One end of the pushing plate 48 away from the guide rod 47 on its same side is bent outward to ensure that the pushing plate 48 can closely fit the end - cover 11, so as to effectively push the end - cover 11 to the correct position during the operation. A spring 49 is sleeved on the T - shaped rod of the guide rod 47. The two ends of the spring 49 are respectively connected to the pushing plate 48 and the T - shaped rod of the guide rod 47. A reed 410 is connected to the side of the mounting plate 45 facing the guide rod 47. The reed 410 is in close contact with the square plate of the guide rod 47. A downward - pressing component for pressing the end - cover 11 into the toner cartridge 10 is provided on the square plate of the guide rod 47. The downward - pressing component includes two left - right lifting rods 411 slidably arranged on the square plate of the guide rod 47. The shape of the lifting rod 411 is U - shaped. A pressing rod 412 is connected between the lower parts of the two left - right lifting rods 411. The lifting rods 411 and the pressing rod 412 are both located between the two left - right pushing plates 48. A wedge - shaped block 413 is connected to the upper part of the lifting rod 411. A T - shaped rod 414 in contact with the wedge - shaped block 413 is connected to the top of the mounting plate 45. A spring 415 is sleeved on the lifting rod 411. The two ends of the spring 415 are respectively connected to the lifting rod 411 and the square plate of the guide rod 47.

[0026] First, place the toner cartridge 10 combined with the end cap 11 on top of the workbench 1 and position it directly below the ultrasonic plastic welding machine 3. Then, control the two cylinders 44 to drive the two mounting plates 45 closer to each other. As a result, the front and rear guide rods 47 are pushed closer to each other through the reed 410, and then the front and rear push plates 48 on both sides are driven closer to each other. Since one end of the push plate 48 away from the guide rod 47 on its same side bends outward, when the end cap 11 and the toner cartridge 10 are not fully engaged or the edge of the end cap 11 is not fully inserted into the toner cartridge 10, the front and rear push plates 48 moving closer to each other can push the end cap 11 to adjust its position in the front-back and left-right directions on the toner cartridge 10. The spring 49 can apply a force to make the left and right push plates 48 closely fit the end cap 11, and then effectively push the end cap 11 to be accurately positioned during the operation. When the square plates on the front and rear guide rods 47 respectively contact the front and rear ends of the end cap 11, the front and rear guide rods 47 and the push plates 48 on both sides cannot move closer to each other anymore. Thus, the front and rear mounting plates 45 drive the front and rear T-shaped rods 414 to continue moving closer to each other, compress the reed 410, and make the T-shaped rod 414 squeeze the inclined surface on the wedge block 413. As a result, the wedge block 413 drives the pressure rod 412 to move downward through the lifting rod 411, compressing the spring 415. The downward movement of the pressure rod 412 presses the end cap 11 into the toner cartridge 10, enabling the automatic adjustment of the alignment between the end cap 11 and the toner cartridge 10, achieving the precise assembly of the end cap 11 and the toner cartridge 10, effectively improving production efficiency and reducing the generation of defective products, and further reducing the loss of materials and costs. After the end cap 11 is accurately positioned, control the two cylinders 44 to drive the two mounting plates 45 away from each other. The reed 410 then returns to its original state, and the T-shaped rod 414 releases the wedge block 413. Under the reset action of the spring 415, the lifting rod 411 drives the pressure rod 412 and the wedge block 413 to move upward and reset. When the mounting plate 45 moves to contact the end of the T-shaped slide rod 46, the two mounting plates 45 continue to move away from each other and pull the front and rear guide rods 47 on both sides away from each other through the T-shaped slide rod 46, thereby driving the front and rear push plates 48 on both sides to move away from each other to avoid interfering with the ultrasonic welding head 31 of the ultrasonic plastic welding machine 3 and preventing it from hindering the subsequent ultrasonic pressing and fixing of the end cap 11 and the toner cartridge 10 by the ultrasonic welding head 31. If the end cap 11 and the toner cartridge 10 are fully engaged and the edge of the end cap 11 is fully inserted into the toner cartridge 10, the front and rear guide rods 47 and the push plates 48 moving closer to each other only slide on the top of the end cap 11 without affecting its position. Next, control the ultrasonic welding head 31 of the ultrasonic plastic welding machine 3 to move downward to perform ultrasonic pressing on the end cap 11 and the toner cartridge 10 to fully press and fix them. The ultrasonic plastic welding machine 3 is a prior art and will not be elaborated here. After the toner cartridge chamber pressing is completed, control the ultrasonic welding head 31 of the ultrasonic plastic welding machine 3 to move upward and reset. Then, remove the assembled toner cartridge chamber and place the toner cartridge 10 combined with the end cap 11 again. This process can be repeated to perform the toner cartridge chamber pressing work cyclically.The control of the electric slide rail 43 drives the lifting plate 42 to lift, which can adjust the heights of the guide rod 47 and the push plate 48 to adapt to toner cartridge bins of different height specifications.

[0027] Embodiment 2: On the basis of Embodiment 1, refer to Figure 2 and Figure 5 , a centering mechanism is provided on the top of the workbench 1 for pushing the toner cartridge 10 to be centered and aligned with the ultrasonic plastic welding machine 3. The centering mechanism includes two sets of guide sleeves 51 connected to the top of the workbench 1, with two guide sleeves 51 in each set. The two guide sleeves 51 in each set are symmetrically arranged left and right. A sliding rod 52 is slidably arranged in each guide sleeve 51. A first positioning plate 53 is connected between the left and right sliding rods 52. A third spring 54 is sleeved on the sliding rod 52, and the two ends of the third spring 54 are respectively connected to the sliding rod 52 and the guide sleeve 51. A conveyor belt 55 is provided in the middle of the first positioning plate 53. A plurality of balls 56 for reducing friction are arranged at intervals on one side of the two first positioning plates 53 close to each other.

[0028] The toner cartridge 10 combined with the end cap 11 is placed between the front and rear first positioning plates 53. The front and rear first positioning plates 53 are pushed away from each other by the toner cartridge 10, and the third spring 54 is compressed. Through the cooperation of the third springs 54 on the front and rear sides and the first positioning plates 53, the toner cartridge 10 can be centered and positioned in the front and rear directions to ensure that the toner cartridge 10 is accurately located directly below the ultrasonic plastic welding machine 3 for pressing the end cap 11, thereby effectively improving the assembly accuracy of the end cap 11 and the toner cartridge 10. After the end cap 11 and the toner cartridge 10 are pressed, the conveyor belt 55 is controlled to work to convey the assembled toner cartridge bin to the left. The balls 56 can reduce the friction between the toner cartridge bin and the first positioning plate 53 to ensure that the toner cartridge bin can be smoothly conveyed to the left.

[0029] Embodiment 3: On the basis of Embodiment 2, refer to Figures 5 - 7, a pushing mechanism for pushing the powder box 10 is provided at the inner bottom of the workbench 1. The pushing mechanism includes two front and rear rodless cylinders 61 connected to the right side of the inner bottom of the workbench 1. Connecting seats 62 are connected to the sliders of the two rodless cylinders 61. Pushing blocks 63 are hinged to the two connecting seats 62. Two front and rear torsion springs 65 are connected between the pushing block 63 and the connecting seat 62. Support blocks 64 are connected to the sliders of the two rodless cylinders 61. The support block 64 is located on the right side of the pushing block 63 and is used to support the pushing block 63. Two guide grooves 01 for the pushing block 63 to slide are opened at the top of the workbench 1. A through groove 02 is opened in the middle of the top of the workbench 1. A positioning mechanism for positioning the powder box 10 is provided in the through groove 02. The positioning mechanism includes an electric push rod 71 installed on the left side in the through groove 02. A movable plate 72 is connected to the telescopic rod of the electric push rod 71. A positioning plate two 73 that can be lifted is slidably connected to the movable plate 72 through a chute. A wedge plate 74 is connected to the lower right part of the positioning plate two 73. Both the left and right sides of the wedge plate 74 are designed with inclined surfaces. A contact rod 75 is connected between the sliders of the two rodless cylinders 61. The left and right reciprocating movement of the contact rod 75 can contact the wedge plate 74. A rubber block 8 is connected to the right side surface of the positioning plate two 73. The powder box 10 can be buffered and protected through the rubber block 8 to avoid damage to the powder box 10 caused by direct hard collision with the positioning plate two 73.

[0030] Place the powder box 10 combined with the end cap 11 on the right side of the top of the workbench 1, and place the powder box 10 combined with the end cap 11 between the two front and rear positioning plates one 53. Control the rodless cylinder 61 to drive the connecting seat 62, the support block 64 and the contact rod 75 to move left and right reciprocally, so as to drive the pushing block 63 to move left and right reciprocally. Since the pushing block 63 is supported by the support block 64 and cannot rotate downward to the right, the pushing block 63 can push the powder box 10 combined with the end cap 11 to the left to the directly below the ultrasonic plastic welding machine 3 when moving left, realizing the automatic feeding of the powder box 10, thus improving the automation level and the pressing efficiency. When the contact rod 75 moves left to contact the inclined surface on the right side of the wedge plate 74, the contact rod 75 continues to move left to squeeze the inclined surface on the right side of the wedge plate 74, so as to push the wedge plate 74 to drive the positioning plate two 73 to move upward to position the powder box 10, avoiding excessive leftward pushing of the powder box 10, ensuring that the powder box 10 is accurately pushed to the directly below the ultrasonic plastic welding machine 3, and thus ensuring the accurate assembly of the end cap 11 and the powder box 10. When the contact rod 75 moves right and disengages from the wedge plate 74, under the action of gravity, the positioning plate two 73 and the wedge plate 74 move downward and reset to avoid the powder box 10 and prevent hindering the subsequent leftward conveying of the powder box 10 by the conveyor belt 55. Controlling the telescopic rod of the electric push rod 71 to shorten or elongate can drive the movable plate 72 to drive the positioning plate two 73 to adjust the position in the left and right directions to adapt to powder boxes 10 of different specifications and sizes, so as to ensure that powder boxes 10 of different specifications and sizes can be accurately pushed to the directly below the ultrasonic plastic welding machine 3.

[0031] Example 4: On the basis of Example 3, refer to Figure 8 , a feeding mechanism is provided between the right sides of the tops of the two positioning plates 53. The feeding mechanism includes a telescopic storage box 91 connected between the right sides of the tops of the two positioning plates 53. The telescopic storage box 91 includes two L-shaped plates 911 respectively connected to the right sides of the tops of the two positioning plates 53. Two guide rods 912 are connected to the left side of the L-shaped plate 911. A vertical plate 913 is slidably connected between the upper and lower guide rods 912. A fourth spring 914 is sleeved on the guide rod 912. The two ends of the fourth spring 914 are respectively connected to the vertical plate 913 and the L-shaped plate 911. Two second electric slide rails 92 are installed on the right side walls of the two L-shaped plates 911. A push block 93 is hinged to the slider of each of the two second electric slide rails 92.

[0032] First, turn the push block 93 to the right out of the telescopic storage box 91 to prevent the push block 93 from hindering the powder box 10 from being placed in the telescopic storage box 91 for storage. Then stack the powder boxes 10 combined with the end caps 11 from bottom to top in the telescopic storage box 91 composed of the L-shaped plates 911, the guide rods 912, the vertical plate 913 and the fourth spring 914. The telescopic storage box 91 composed of the L-shaped plates 911, the guide rods 912, the vertical plate 913 and the fourth spring 914 can not only store powder boxes 10 of different specifications and sizes, but also position the powder boxes 10 stacked from bottom to top to prevent the powder boxes 10 stacked from bottom to top from collapsing and scattering. Then turn the push block 93 back to the left into the telescopic storage box 91. After the powder box 10 combined with the end cap 11 at the lowermost end in the telescopic storage box 91 is pushed away to the left by the push block 63, control the second electric slide rail 92 to drive the push block 93 to move downwards, and push the powder box 10 combined with the end cap 11 in the telescopic storage box 91 downwards, so that the next powder box 10 combined with the end cap 11 moves down to the workbench 1, so as to realize the automatic continuous feeding of the powder boxes 10, further improving the automation level and the pressing efficiency. When the push block 63 moves to the right and contacts the lowermost powder box 10 in the telescopic storage box 91, the push block 63 continues to be pushed to the right by the lowermost powder box 10 in the telescopic storage box 91 and turns left and downwards, compressing the torsion spring 65. When the push block 63 moves to the right beyond the lowermost powder box 10 in the telescopic storage box 91, under the reset action of the torsion spring 65, the push block 63 turns right and upwards to reset, preparing for pushing the next powder box 10.
