Description

Technical Field

[0001] This application relates to the field of waste disposal technology, and in particular to an automatic baling device. Background Technology

[0002] Automatic packaging devices are core equipment for the integrated collection and sealing of materials. They are widely used in pet litter processing, small-scale waste collection, and other scenarios. The core function is to replace manual operation with mechanical automation, thereby improving processing efficiency, hygiene, and standardization, and meeting the needs of rapid batch processing.

[0003] Some existing automatic packaging devices use a negative pressure suction bag structure. During operation, a negative pressure pump creates a negative pressure environment inside the bag box. The suction nozzle at the bag outlet sucks up the edge of the folded garbage bag, and the rotation of the conveyor roller pulls the garbage bag downward to achieve the bag's placement. After receiving the material, the sealing mechanism below completes the sealing through fusion or compression, forming a basic automated process.

[0004] However, this structure has extremely high requirements for the airtightness of the bag box. Even a slight gap can lead to insufficient negative pressure, which will cause the suction bag to fail. It is also unable to adapt to folded garbage bags with uneven surfaces. Negative pressure failure or component jamming will prolong the single packing cycle, resulting in problems such as low processing efficiency and high failure risk, making it difficult to achieve efficient and stable automated processing. Utility Model Content

[0005] This application provides an automatic packaging device to solve the technical problem that existing technologies struggle to achieve efficient and stable automated processing.

[0006] This application proposes an automatic packaging device, comprising:

[0007] Mounting base;

[0008] A bag box is provided on the mounting base. The bag box contains a folded garbage bag. The bag box has an outlet on its inner side and several clamping parts are provided around the outlet.

[0009] A bag-dropping mechanism is located below the bag box. The bag-dropping mechanism includes a driving component and a transmission component. The transmission component and the clamping member are spaced apart. The garbage bag moves between the transmission component and the clamping member through the driving component.

[0010] A sealing mechanism is provided below the lower bag mechanism and is used to seal and pack the garbage bag.

[0011] Furthermore, the mounting base has a lower bag channel and a mounting groove running through its center. The mounting groove has a through hole in its center, which communicates with the lower bag channel. The bag box can be detachably installed in the mounting groove.

[0012] Furthermore, the bag box has a ring structure, and the garbage bag is folded and placed inside the ring channel of the bag box.

[0013] Furthermore, the top of the bag box protrudes from the top of the mounting base, and the top of the mounting base is provided with several elastic buckles located on the outer periphery of the bag box to limit the position of the bag box after installation.

[0014] Furthermore, the drive assembly includes a drive element and a gear transmission pair, the output end of the drive element is connected to the gear transmission pair, and the output end of the gear transmission pair meshes with the transmission end of the transmission assembly.

[0015] Furthermore, the transmission component is a gear transmission mechanism, which includes a plurality of first transmission components and a first lower bag wheel. The plurality of first transmission components are connected in sequence to form a ring structure corresponding to the bag box, and a first lower bag wheel is sleeved in the middle of each first transmission component. The garbage bag is clamped between the first lower bag wheel and the clamping component.

[0016] Furthermore, the first transmission member has a spur gear at its head end, which meshes with the gear transmission pair, and a helical gear at its tail end, which meshes with the adjacent first transmission member; the first transmission members in the middle have helical gears at both their head and tail ends, and they mesh with each other for transmission; the last transmission member has a helical gear at one end and a smooth surface at the other end, and is not connected to the first transmission member.

[0017] Furthermore, the transmission component is a universal joint transmission mechanism, which includes multiple second transmission components and a second lower bag wheel. The multiple second transmission components are connected in sequence to form a ring structure corresponding to the bag box, and each second transmission component is fitted with a second lower bag wheel in the middle. The garbage bag is clamped between the second lower bag wheel and the clamping component.

[0018] Furthermore, the first second transmission component has a spur gear at its head end, which meshes with the gear transmission pair, and a universal joint at its tail end, which is rotatably connected to the adjacent second transmission component; the first and tail ends of each of the middle second transmission components are universal joints, and they are rotatably connected to each other; the last second transmission component has a universal joint at one end and a smooth surface at the other end, and is not connected to the first transmission component.

[0019] Furthermore, the automatic packaging device also includes a control unit, which is electrically connected to the drive assembly to control the lower length of the garbage bag.

[0020] The technical solutions provided in this application have the following advantages compared with the prior art:

[0021] This application utilizes clamping components around the bag outlet to stably position folded garbage bags. The coordinated action of the drive and transmission components in the bag-feeding mechanism provides continuous and stable conveying power for the garbage bags. The gap between the transmission component and the clamping components avoids component jamming caused by rigid contact and eliminates the need for the strict sealing required by the negative pressure suction bag structure. This effectively solves the problem of bag failure caused by insufficient negative pressure in existing negative pressure suction bag structures. At the same time, this gap design can accommodate folded garbage bags with uneven surfaces, preventing bag jamming during bag feeding. Furthermore, the sealing mechanism below can promptly seal the garbage bag after it has been smoothly fed and received the material. This makes the "positioning-bag feeding-material receiving-sealing" process continuous and efficient, solving the problems of long single-packing cycles and high failure risks in existing devices. Ultimately, it achieves efficient and stable automated processing, further improving the efficiency, hygiene, and standardization of material handling, and better meeting the needs of rapid batch processing.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0039] To address the technical challenge of achieving efficient and stable automated processing in existing technologies, this application utilizes clamping components 23 around the bag outlet 22 of the bag box 2 to stably position the folded garbage bag 21. The synergistic effect of the drive component 31 and transmission component 32 in the bag lowering mechanism 3 provides continuous and stable conveying power to the garbage bag 21. The gap between the transmission component 32 and the clamping component 23 avoids component jamming caused by rigid contact and eliminates the need for the strict sealing required by the negative pressure suction bag structure. This solves the problems of long single-packing cycles and high failure risks in existing devices, ultimately achieving efficient and stable automated processing. This further improves the efficiency, hygiene, and standardization of material handling, better meeting the needs of rapid batch processing.

[0040] Please see Figures 1 to 6 This application proposes an automatic packaging device, including: a mounting base 1, a bag box 2, a bag lowering mechanism 3, and a sealing mechanism 4; the bag box 2 is mounted on the mounting base 1, and a folded garbage bag 21 is provided inside the bag box 2. The bag box 2 has a bag outlet 22 on its inner side, and a plurality of clamping members 23 are provided around the bag outlet 22; the bag lowering mechanism 3 is located below the bag box 2, and the bag lowering mechanism 3 includes a driving component 31 and a transmission component 32. The transmission component 32 and the clamping members 23 are spaced apart, and the garbage bag 21 moves between the transmission component 32 and the clamping members 23 through the driving component 31; the sealing mechanism 4 is located below the bag lowering mechanism 3 and is used to seal and package the garbage bag 21.

[0041] Specifically, when the automatic packaging device is working, in the initial state, one end of the folded garbage bag 21 extends to the sealing area of ​​the sealing mechanism 4. The sealing mechanism 4 starts to seal the end for the first time, forming a closed bottom end of the garbage bag 21. After the first sealing is completed, the drive component 31 drives the transmission component 32 to operate. Through the friction between the transmission component 32 and the surface of the garbage bag 21, and with the limiting effect of the clamping component 23, the sealed bottom end of the garbage bag 21 is guided to move smoothly downward along the gap until it reaches the preset material receiving position. The material falls into the garbage bag 21 through the bag outlet 22 of the bag box 2 to complete the material receiving. After the material receiving is completed, the sealing mechanism 4 starts again to seal the open end of the garbage bag 21 for the second time. After sealing, the single automatic packaging process is completed. The sealing mechanism 4 uses a conventional heat sealing device (such as a heat sealing machine or a cable tie sealing machine) to heat and seal the opening of the garbage bag 21.

[0042] Compared to existing technologies, this embodiment forms a closed material-bearing space through the initial sealing, preventing material leakage during material feeding; the gap design between the transmission component 32 and the clamping component 23 ensures smooth and unobstructed movement of the lower bag; the process of "initial sealing-lowering bag-feeding-secondary sealing" is closely connected, and the structural design is adapted to this working logic; the whole process achieves full automation of material sealing and storage, improving the sealing, reliability and hygiene of packaging.

[0043] like Figure 1-2 As shown, the mounting base 1 has a lower bag channel 12 and a mounting groove 11 through the middle. The mounting groove 11 has a through hole 111 in the middle and communicates with the lower bag channel 12. The bag box 2 can be detachably installed in the mounting groove 11.

[0044] Specifically, a vertically extending lower bag channel 12 is machined through the middle of the mounting base 1, serving as the conveying path for the garbage bag 21. A mounting groove 11 is machined at a preset position on the mounting base 1, the outline of which matches the shape of the bag box 2. A through hole 111 is opened in the middle of the mounting groove 11, ensuring that the axis of the through hole 111 is collinear with the axis of the lower bag channel 12 during machining, so that the two are fully connected. The inner wall of the mounting groove 11 is provided with a detachable connection structure, such as an elastic buckle 13 or a positioning slot, and a matching connecting part, such as a locking block or a protruding ridge, is provided on the outer side of the bag box 2. During assembly, align the bag box 2 with the mounting groove 11, ensuring the connecting part of the bag box 2 is aligned with the connecting structure of the mounting groove 11. Smoothly push it into the mounting groove 11 until it engages and is securely fixed, completing the detachable installation of the bag box 2. At this point, the bag outlet 22 of the bag box 2 precisely aligns with the through hole 111 of the mounting groove 11, allowing the garbage bag 21 to enter the lower bag channel 12 through the bag outlet 22 and the through hole 111 of the mounting groove 11, forming a continuous conveying path. When it is necessary to replace the bag box 2 or replenish the garbage bag 21, simply pull the bag box 2 outwards to disengage the connecting structure, thus completing the disassembly.

[0045] like Figure 1 and Figure 4As shown, the bag box 2 has a ring structure, and the garbage bag 21 is folded and placed in the ring channel 24 inside the bag box 2.

[0046] Specifically, in this embodiment, the bag box 2 is manufactured as a ring structure, forming a closed ring channel 24 through the inner and outer side walls. The width and height of the ring channel 24 are adapted to the size of the folded garbage bag 21. A bag outlet 22 is opened at a predetermined position on the ring side wall of the bag box 2. The bag outlet 22 is connected to the inside of the ring channel 24, and the edge of the bag outlet 22 is smoothed to avoid scratching the garbage bag 21. The folded garbage bags 21 are stacked sequentially along the circumference of the ring channel 24, so that the garbage bags 21 neatly fill the ring space. Then, the open end of the outermost garbage bag 21 is pulled to the bag outlet 22 and initially fixed to ensure that the garbage bag 21 can be smoothly led out along the bag outlet 22. During operation, the bag-feeding mechanism 3 applies traction force to the garbage bag 21 at the bag outlet 22 through the transmission component 32. The folded garbage bag 21 is released in an orderly manner from the annular channel 24 and enters the subsequent bag-feeding and packaging process through the bag outlet 22. When the garbage bag 21 in the annular channel 24 is about to run out, the detachable bag box 2 can be removed for replenishment or replacement, making the operation convenient.

[0047] like Figure 1 As shown, the top of the bag box 2 protrudes from the top of the mounting base 1. The top of the mounting base 1 is provided with several elastic buckles 13, which are located on the outer periphery of the bag box 2 to limit the bag box 2 after installation.

[0048] Specifically, a mounting position for the bag box 2 is machined in a preset area on the top of the mounting base 1, ensuring that the depth of the mounting position is less than the height of the bag box 2, so that the top of the bag box 2 can naturally protrude from the top of the mounting base 1 after installation. Around the outer periphery of the mounting position, several elastic buckles 13 are evenly arranged circumferentially. Each elastic buckle 13 consists of a clamping arm and an elastic rotating shaft. The elastic rotating shaft is installed on a fixed base on the top of the mounting base 1. In its natural state, the clamping arm is in a closed clamping state with the top of the bag box 2 under the action of the elastic rotating shaft. Shallow grooves are machined on the outer periphery of the bag box 2 corresponding to the buckle positions to enhance the stability of the clamping and limiting. When it is necessary to disassemble the bag box 2 to replenish or replace the garbage bag 21, press down on the elastic buckle 13 to disengage it from the limiting position of the bag box 2, and then remove the bag box 2 upwards. Reinstallation is done by repeating the pressing action, making the operation convenient. After the bag box 2 is installed, the garbage bag 21 inside can be smoothly discharged through the lower structure without affecting the subsequent bag-feeding and packaging process.

[0049] It is understood that in this embodiment, there are two elastic buckles (13 pieces) respectively located on opposite sides of the outer periphery of the bag box 2. In other embodiments, the number of elastic buckles (13 pieces) may be three, four or more, depending on the actual situation. No limitation is made here.

[0050] like Figure 5-6As shown, the drive assembly 31 includes a drive member 311 and a gear transmission pair 312. The output end of the drive member 311 is connected to the gear transmission pair 312, and the output end of the gear transmission pair 312 meshes with the transmission end of the transmission assembly 32.

[0051] Specifically, the mounting bracket of the drive assembly 31 is fixed to a preset position on the bag-dropping mechanism 3, and the drive component 311 is fixed on the bracket. The output end of the drive component 311 is machined into a gear shaft structure or a mounting adapter connecting flange. A gear transmission pair 312 consisting of a drive gear and a driven gear is selected. The drive gear is fitted onto the output end of the drive component 311 and tightened to ensure no relative slippage. The driven gear is mounted on the rotating shaft of the bracket through a bearing. The position is adjusted to ensure precise meshing between the drive gear and the driven gear, and grease is applied to the meshing point to reduce wear. Then, the transmission end of the transmission assembly 32 (pre-set as a gear structure) is aligned with the driven gear, and the installation position of the transmission assembly 32 is adjusted to achieve smooth meshing. During operation, the drive component 311 starts to output torque, driving the drive gear to rotate. The drive gear drives the driven gear to rotate through meshing, and the driven gear then transmits power to the transmission end of the transmission assembly 32, causing the transmission assembly 32 to rotate and drive the garbage bag 21 to complete the bag-dropping movement. In this structure, the gear transmission pair 312 has high transmission accuracy, ensuring stable power transmission between the drive component 311 and the transmission assembly 32; at the same time, the meshing transmission efficiency is high and the torque loss is small, making the movement of the lower bag smooth and controllable.

[0052] It is understood that the driving component 311 in this embodiment is a drive motor. In other embodiments, the driving component 311 may be an electromagnetic driving component 311, a pneumatic driving component 311, a hydraulic driving component 311, etc. The specific choice can be made according to the actual situation, and no limitation is made here.

[0053] like Figure 5 As shown, the transmission component 32 is a gear transmission mechanism, which includes multiple first transmission components 321 and a first lower bag wheel 322. The multiple first transmission components 321 are connected in sequence to form a ring structure corresponding to the bag box 2. Each first transmission component 321 is fitted with a first lower bag wheel 322 in the middle. The first lower bag wheel 322 clamps the garbage bag 21 between itself and the clamping component 23.

[0054] Specifically, the mounting bracket of the gear transmission mechanism is fixed at a preset position on the lower bag mechanism 3, ensuring that the bracket position corresponds to the bag outlet 22 of the bag box 2. Several first transmission components 321 (gear structure) with identical structures are selected, and each first transmission component 321 is sequentially installed on the bracket, so that adjacent first transmission components 321 mesh with each other, ultimately forming an annular structure that matches the shape of the bag box 2. The inner contour of this annular structure matches the outer contour of the bag outlet 22 of the bag box 2. A first lower bag wheel 322 is installed at a preset mounting position in the middle of each first transmission component 321 and fixed by key connection or tight fit, ensuring that the first lower bag wheel 322 rotates synchronously with the first transmission component 321. The wheel surface of each first lower bag wheel 322 forms a corresponding gap with the clamping member 23 on the periphery of the bag outlet 22 of the bag box 2, pulling the extended end of the folded garbage bag 21 between the first lower bag wheel 322 and the clamping member 23, forming a stable clamping through their cooperation. The output end of the drive assembly 31 is engaged with the first transmission component 321 in the annular structure to complete the power transmission connection. During operation, the drive assembly 31 drives the first transmission component 321 engaged with it to rotate. Through gear meshing, it drives all the first transmission components 321 in the annular structure to rotate synchronously. The first lower bag wheel 322 rotates with the first transmission component 321. Utilizing the friction between the wheel surface and the garbage bag 21, and in conjunction with the limiting effect of the clamping component 23, it drives the garbage bag 21 to move smoothly downward, realizing the bag lowering action.

[0055] like Figure 5 As shown, the first transmission component 321 has a spur gear at its head end, which meshes with the gear transmission pair 312, and a helical gear at its tail end, which meshes with the adjacent first transmission component 321; the first transmission components 321 in the middle have helical gears at both ends, and they mesh with each other for transmission; the last transmission component 321 has a helical gear at one end and a smooth surface at the other end, and is not connected to the first transmission component.

[0056] Specifically, during assembly, the first transmission component 321 is first installed at the starting position of the bracket, with its spur gear end facing the gear transmission pair 312 of the drive assembly 31. The position is adjusted to achieve precise meshing between the spur gear and the gear transmission pair 312. Next, each intermediate first transmission component 321 is installed sequentially, so that the tail helical gear of the previous transmission component meshes with the head helical gear of the next transmission component in pairs, forming a continuous transmission link. Finally, the last transmission component is installed, with its helical gear end meshing with the tail helical gear of the second-to-last intermediate transmission component, and its smooth surface end facing the spur gear side of the first transmission component, maintaining a non-contact state. All transmission components together form a ring structure corresponding to the bag box 2. During operation, the drive assembly 31 drives the spur gear of the first transmission component 321 to rotate via the gear transmission pair 312. The helical gear at its tail end transmits power to the adjacent intermediate transmission components. The intermediate transmission components transmit power sequentially through the meshing of the first and last helical gears, ultimately driving the last transmission component to rotate. All the first bag-dropping wheels 322 rotate synchronously with the transmission components. Utilizing the friction between the wheel surface and the garbage bag 21, along with the clamping component 23 for positioning, the garbage bag 21 is smoothly lowered. This structure ensures efficient power input through the meshing of the spur gear and the gear transmission pair 312, and the helical gear meshing transmission is smooth and low-noise. The ring layout adapts to the bag box 2 structure, and the synchronous drive of multiple bag-dropping wheels ensures uniform force on the garbage bag 21. The smooth end of the last transmission component avoids interference, improving structural adaptability and ensuring smooth and stable bag dropping overall.

[0057] like Figure 6 As shown, in another embodiment, the transmission assembly 32 is a universal joint transmission mechanism. The universal joint transmission mechanism includes multiple second transmission components 323 and second lower bag wheels 324. The multiple second transmission components 323 are sequentially connected to form a ring structure corresponding to the bag box 2. Each second transmission component 323 has a second lower bag wheel 324 fitted in its center. The second lower bag wheel 324 clamps the garbage bag 21 between itself and the clamping component 23. The transmission principle is similar to that of a gear transmission mechanism and will not be elaborated here.

[0058] like Figure 6 As shown, the first second transmission component 323 has a spur gear at its head end, which meshes with the gear transmission pair 312, and a universal joint at its tail end, which is rotatably connected to the adjacent second transmission component 323; the first and tail ends of each of the middle second transmission components 323 are universal joints, and they are rotatably connected to each other; the last second transmission component 323 has a universal joint at one end and a smooth surface at the other end, and is not connected to the first transmission component.

[0059] Specifically, in this embodiment, the first second transmission component 323 is fixed at the starting position of the bracket, and its angle is adjusted so that the spur gear end is fully engaged with the gear transmission pair 312 of the drive assembly 31. Next, the intermediate transmission components are installed sequentially, achieving rotational connection through the universal joint joints of adjacent transmission components. Utilizing the angle compensation capability of the universal joints, the transmission link can be flexibly adjusted according to layout requirements. Finally, the end transmission component is installed, connecting its universal joint joint to the joint of the second-to-last intermediate transmission component, with the smooth surface end facing the spur gear side of the first transmission component, maintaining a non-contact state. All transmission components together form a ring structure corresponding to the bag box 2. During operation, the drive assembly 31 drives the first transmission component to rotate through the gear transmission pair 312. Power is transmitted sequentially to the intermediate and end transmission components via its tail universal joint. All second transmission components 323 operate synchronously, and the second lower bag wheel 324 rotates with the transmission components. Using the friction of the wheel surface in conjunction with the clamping component 23 for limiting, the garbage bag 21 is smoothly lowered. This structure ensures precise power input through the meshing of spur gears and gear transmission pair 312, while the universal joint connection can adapt to the angle requirements of the annular layout, reducing the impact of assembly errors.

[0060] Furthermore, such as Figure 2 As shown, the mating end of the clamping member 23 with the first lower bag wheel 322 or the second lower bag wheel 324 is configured as a gear.

[0061] Specifically, when installing the bag-lowering mechanism 3, the position of the bag-lowering wheel is adjusted so that the gear of the bag-lowering wheel and the gear of the clamping member 23 form a corresponding engagement—the two maintain a slight gap to accommodate the garbage bag 21, while the positions of the gear tooth peaks and valleys are relatively staggered, forming a meshing tendency but not directly biting. The garbage bag 21 is pulled between the gear of the clamping member 23 and the gear of the bag-lowering wheel, and the concave and convex structure of the gear tooth surface forms a bidirectional limit for the garbage bag 21. During operation, the bag-lowering wheel rotates under the drive of the drive component 31, and its gear tooth surface generates friction with the surface of the garbage bag 21. At the same time, the gear tooth surface of the clamping member 23 restricts the garbage bag 21 from deviating, jointly driving the garbage bag 21 to move smoothly downward along the gear engagement gap, completing the bag-lowering action. Among them, the gear engagement can increase the contact friction with the garbage bag 21 and prevent the bag from slipping; the tooth structure forms a precise limit for the garbage bag 21, preventing deviation and tearing.

[0062] In an optional embodiment, the automatic packaging device further includes a control unit electrically connected to the drive assembly 31 to control the lower bag length of the garbage bag 21.

[0063] Specifically, the control unit is fixed on the mounting base 1 of the automatic packaging device or the bracket of the bag-dropping mechanism 3, ensuring that its installation position is convenient for wiring and not easily affected by vibration. The signal output terminal of the control unit is electrically connected to the control input terminal of the drive component 31 through a wire to establish a control signal transmission link between the two; at the same time, a detection element (such as a position sensor or encoder) for detecting the moving distance of the garbage bag 21 is installed on the transmission component 32 or the bag-dropping path, and the signal output terminal of the detection element is electrically connected to the signal input terminal of the control unit to form a closed-loop control circuit. Before operation, the target bag-feeding length parameter of the garbage bag 21 is preset by the control unit. During operation, the control unit sends a start signal to the drive component 31, which drives the transmission component 32 to transport the garbage bag 21. The detection element collects the moving distance of the garbage bag 21 or the operating parameters of the transmission component 32 in real time and feeds the data back to the control unit. The control unit processes the feedback data, and when it determines that the actual bag-feeding length of the garbage bag 21 has reached the preset value, it immediately sends a stop signal to the drive component 31, which stops operating, completing a single precise bag-feeding control. After the subsequent material receiving and sealing processes are completed, the control unit can start the next bag-feeding control cycle according to the instruction. This application achieves precise and controllable bag-feeding length through the electrical connection between the control unit and the drive component 31, avoiding insufficient material receiving or waste of the garbage bag 21. At the same time, automated control reduces manual intervention and enhances the standardization and stability of the device operation.
