Description

Technical Field

[0001] This invention relates to the field of coating technology, and in particular to a coating device for the shell of a sweeping robot and a coating shell forming equipment. Background Technology

[0002] With the rapid development of smart home technology, robotic vacuum cleaners have become an important tool for cleaning modern homes. Their automated functions, integrating vacuuming and mopping, significantly improve the quality of life. While meeting functional requirements, the market has also placed higher demands on the product's appearance design. The back shell of robotic vacuum cleaners is often formed by injection molding. To give the back shell of the robotic vacuum cleaner a specific texture, pattern, or color, a plastic film with corresponding decorative effects is usually pre-attached to the injection mold. Then, the injection molding process is carried out to integrate the film with the back shell of the robotic vacuum cleaner, thus achieving the goal of attaching the decorative plastic film inside the back shell of the robotic vacuum cleaner.

[0003] Current film application methods primarily rely on manual handling, where the film is picked up and applied to the injection mold cavity. This method is inefficient, the repetitive nature of the work leads to excessive labor intensity, and the precision of manually applied films is low, making it difficult to ensure consistent placement. Defects such as misalignment, wrinkles, or residual micro-air bubbles are easily produced, severely impacting the appearance and overall quality of the molded product. Therefore, there is an urgent need for automated film application equipment. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a robotic vacuum cleaner shell coating device and a coated shell forming equipment, which can achieve automated film application, improve film application quality, and increase yield and production efficiency.

[0005] This invention provides a film coating device for a robotic vacuum cleaner shell, used to coat a film onto a mold of an injection molding device. The mold is used to form the robotic vacuum cleaner shell. The robotic vacuum cleaner shell film coating device includes: a bracket, an adjustment mechanism disposed on the bracket, an adsorption component, and a roller assembly disposed on the adsorption component. The roller assembly is slidable relative to the adsorption component. The adsorption component is rotatably connected to the adjustment mechanism to drive the roller assembly to rotate. The adjustment mechanism is used to adjust the position of the adsorption component in a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are mutually perpendicular. The adsorption component has a first state and a second state. The adsorption component switches between the first state and the second state by rotating a preset angle relative to the adjustment mechanism. In the first state, the adsorption component is used to adsorb the film. In the second state, the adsorption component is used to coat the film. The roller assembly is used to roll and press the coated film.

[0006] In one embodiment, the adjustment mechanism includes an X-line module fixedly mounted on the bracket, a Y-line module mounted on the X-line module, and a Z-line module mounted on the Y-line module. The Y-line module is movable relative to the X-line module along the first direction, and the Z-line module is movable relative to the Y-line module along the second direction and the third direction.

The suction cups pass through the first clearance holes. The roller assembly is disposed on the second connecting plate and the roller assembly is slidable relative to the second connecting plate.

[0008] In one embodiment, the adsorption assembly further includes a plurality of first air nozzles and a plurality of second air nozzles. The plurality of first air nozzles are spaced apart along the second direction on the side of the first connecting plate away from the Z-line module and located between the two sets of suction cup assemblies. Each set of suction cup assemblies has a plurality of second air nozzles on the side away from the first air nozzles. The plurality of second air nozzles are spaced apart along the second direction on the side of the first connecting plate away from the Z-line module. The second connecting plate has a plurality of second clearance holes spaced apart along the second direction on the side facing the first connecting plate and located between the two sets of suction cup assemblies. The second clearance hole corresponds one-to-one with a plurality of first air nozzles. Each first air nozzle passes through the corresponding second clearance hole. The two ends of the second connecting plate facing the first connecting plate are respectively provided with a plurality of third clearance holes spaced apart along the second direction. The plurality of third clearance holes correspond one-to-one with a plurality of second air nozzles. Each second air nozzle passes through the corresponding third clearance hole. In the first state, the first air nozzle and the second air nozzle are used to remove dust from the diaphragm. In the second state, the first air nozzle and the second air nozzle are used to press the diaphragm after it has been applied by air jet.

[0009] In one embodiment, in the first state, the airflow ejected by the first jet nozzle is greater than the airflow ejected by the second jet nozzle, and in the second state, the airflow ejected by the first jet nozzle is less than the airflow ejected by the second jet nozzle.

[0011] In one embodiment, the third connecting plate is provided with a slide rail on the side away from the second connecting plate, the sliding plate is movably disposed on the slide rail, and mounting plates extending out of the sliding plate are respectively provided on both sides of the sliding plate near the end of the second connecting plate, a fixed shaft is provided between the two mounting plates, and the roller is sleeved on the fixed shaft.

[0012] In one embodiment, the robotic vacuum cleaner shell coating device further includes a flipping drive component fixedly disposed on the Z-line module.

[0032] Example 1

[0033] Please refer to Figures 1-5 This invention illustrates a robotic vacuum cleaner shell coating device 100 provided in an embodiment of the present invention, used to coat a film 6 onto a mold 201 of an injection molding device 200. The mold 201 is used to form a robotic vacuum cleaner shell 5. The robotic vacuum cleaner shell coating device includes: a support 1, an adjustment mechanism 2 disposed on the support 1, an adsorption component 3, and a roller assembly 4 disposed on the adsorption component 3. The roller assembly 4 can slide relative to the adsorption component 3. The adsorption component 3 is rotatably connected to the adjustment mechanism 2 to drive the roller assembly 4 to rotate. The adjustment mechanism 2 is used to adjust the position of the adsorption component 3 in the first direction X, the second direction Y, and the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The adsorption component 3 has a first state and a second state. The adsorption component 3 switches between the first state and the second state by rotating relative to the adjustment mechanism 2 by a preset angle. In the first state, the adsorption component 3 is used to adsorb the film 6. In the second state, the adsorption component 3 is used to coat the film 6. The roller assembly 4 is used to roll and press the coated film 6.

[0034] It needs to be explained, such as Figures 7-9As shown, the diaphragm 6 is a textured, patterned, or colored plastic sheet with a rectangular structure. The diaphragm 6 has a slight elasticity; after a small bending, it can naturally return to its original straight state after the external force is removed. The mold 201 used to mold the robot vacuum cleaner shell 5 is an injection mold. No more than two-thirds of the diaphragm 6 is coated with an adhesive layer 7 to enhance its adhesion and better fit with the mold 201 used to mold the robot vacuum cleaner shell 5. The adhesive layer 7 is a TPU plastic adhesive layer. Through the injection molding process, the robot vacuum cleaner shell 5 and the diaphragm 6 are bonded together to form the final product. At this point, the robot vacuum cleaner shell 5 and the diaphragm 6 are integrated, giving the product textured, patterned, or colored characteristics.

[0035] Specifically, the first direction X is the length direction of the robot vacuum cleaner shell covering device 100, the second direction Y is the width direction of the robot vacuum cleaner shell covering device 100, and the third direction Z is the height direction of the robot vacuum cleaner shell covering device 100. The adjustment mechanism 2 can adjust the position of the adsorption component 3 in the horizontal direction (i.e., the first direction X and the second direction Y) and the vertical direction (i.e., the third direction Z).

[0036] Specifically, such as Figures 2-3 As shown, with a preset angle of 90°, when the robotic vacuum cleaner shell coating device 100 is working, the adsorption component 3 has a first state and a second state. The first state is a horizontal state, and the second state is a vertical state. The adsorption component 3 switches between the first state and the second state by rotating 90° relative to the adjustment mechanism 2. In the first state, both the adsorption component 3 and the film 6 are horizontal, which facilitates the adsorption component 3 to pick up the film 6. After the adsorption component 3 rotates 90° relative to the adjustment mechanism 2, it switches to the second state (i.e., the vertical state). Then, the position of the adsorption component 3 is adjusted by the adjustment mechanism 2 so that the film 6 in the vertical state is attached to the mold 201 used to form the robotic vacuum cleaner shell 5. Then, the roller assembly 4 rolls the film 6 attached to the mold 201, so that the film 6 and the mold 201 are further bonded. Finally, the injection molding device 200 performs injection molding, and the film 6 is completely bonded to the inside of the robotic vacuum cleaner shell 5 and integrated with the robotic vacuum cleaner shell 5 to obtain the final product.

[0037] The position of the adsorption component 3 is adjusted and precisely positioned by the adjustment mechanism 2. Combined with the flip-out connection between the adsorption component 3 and the adjustment mechanism 2, the film 6 is efficiently and accurately picked up and placed, which greatly improves the efficiency and accuracy of automatic film application, reduces manual intervention and reduces human operation error. At the same time, the roller assembly 4 performs rolling to eliminate air bubbles and unevenness, improves the film application quality, increases the yield and production efficiency, and reduces production costs.

[0038] In order to achieve the effect of adjusting the position of the adsorption component 3 to adsorb or attach the membrane 6, and considering structural stability, adjustment accuracy and automation adaptability, a three-line module adjustment mechanism 2 with two perpendicular intersections is adopted.

[0039] Specifically, such as Figures 1-3 As shown, the positioning mechanism 2 includes an X-line module 21 fixed on the bracket 1, a Y-line module 22 on the X-line module 21, and a Z-line module 23 on the Y-line module 22. The Y-line module 22 can move relative to the X-line module 21 along the first direction X, and the Z-line module 23 can move relative to the Y-line module 22 along the second direction Y and the third direction Z. The adsorption component 3 is rotatably connected to the Z-line module 23.

[0040] Specifically, the X-line module 21 is fixedly mounted on the bracket 1 along the first direction X, the Y-line module 22 is mounted on the X-line module 21 along the second direction Y, so that the X-line module 21 and the Y-line module 22 are perpendicular, and the Z-line module 23 is mounted on the Y-line module 22 along the third direction Z, so that the Y-line module 22 and the Z-line module 23 are perpendicularly intersecting.

[0041] The X-linear module 21 can drive the Y-linear module 22, Z-linear module 23, adsorption component 3, and roller assembly 4 to move along the first direction X (i.e., the length direction). The Y-linear module 22 can drive the Z-linear module 23, adsorption component 3, and roller assembly 4 to move along the second direction Y (i.e., the width direction). The Z-linear module 23 can drive the adsorption component 3 and roller assembly 4 to move along the third direction Z (i.e., the height direction). The three modules work together to adjust the horizontal (i.e., the first direction X and the second direction Y) and height positions of the adsorption component 3 and roller assembly 4, so that the adsorption component 3 can be accurately moved above the film 6 to complete adsorption. Alternatively, the adsorption component 3 and roller assembly 4 can be adjusted to the position corresponding to the mold 201 on the injection molding device 200 for film application or rolling, realizing automated film application and rolling, further improving production efficiency and saving costs.

[0042] Specifically, the X linear module 21 is a single-stroke electric slide, the Y linear module 22 is a single-stroke electric slide, and the Z linear module 23 is a single-stroke electric slide; or the X linear module 21, the Y linear module 22, and the Z linear module 23 together constitute a three-axis servo manipulator, which can adjust the position of the adsorption component 3 in the first direction X, the second direction Y, and the third direction Z.

[0043] Specifically, such as Figures 1-5As shown, the adsorption assembly 3 includes a first connecting plate 31, a second connecting plate 32, a spacer plate 37, and two sets of suction cup assemblies. The first connecting plate 31 is rotatably connected to the Z-line module 23. The second connecting plate 32 is located on the side of the first connecting plate 31 away from the Z-line module 23, and the spacer plate 37 is located between the first connecting plate 31 and the second connecting plate 32. The two sets of suction cup assemblies are spaced along the first direction X on the side of the first connecting plate 31 away from the Z-line module 23. Each set of suction cup assemblies includes multiple suction cups 33 spaced along the second direction Y. The second connecting plate 32 has multiple first clearance holes 321 spaced along the second direction Y on the side facing the first connecting plate 31. The suction cups 33 pass through the first clearance holes 321 to achieve adsorption of the membrane 6. The roller assembly 4 is located on the second connecting plate 32, and the roller assembly 4 can slide relative to the second connecting plate 32.

[0044] Specifically, in the first state, the suction cup 33 is used to adsorb the membrane 6, and in the second state, the suction cup 33 is used to attach the membrane 6.

[0045] Multiple suction cups 33 are arranged at intervals on the side of the first connecting plate 31 away from the Z-line module 23 to form spaced adsorption points. During operation, the suction cups 33 generate negative pressure through an external negative pressure device, and the air pressure difference forms a uniformly distributed adsorption force on the diaphragm 6 to ensure that the diaphragm 6 is subjected to balanced force, avoid deformation caused by single-point force, and protect the texture, pattern and color of the diaphragm 6 surface from damage.

[0046] Under normal circumstances, when the membrane 6 is attached to the mold 201 used to form the robot vacuum cleaner shell 5 through the adsorption component 3, there are air bubbles and unevenness on the membrane 6, resulting in poor attachment quality. This leads to poor product quality and low appearance yield, and also affects the injection molding effect of the robot vacuum cleaner shell 5. By setting the roller component 4 to roll the attached membrane 6, air bubbles and unevenness are eliminated, the attachment quality is improved, and the yield and production efficiency are increased.

[0047] Specifically, such as Figures 1-5 As shown, the roller assembly 4 includes a third connecting plate 41 vertically disposed on the second connecting plate 32, a driving member 44 fixedly disposed on the third connecting plate 41, a sliding plate 43 movably connected to the third connecting plate 41, and a roller 42 disposed on the sliding plate 43 near the end of the second connecting plate 32. The driving member 44 is connected to the sliding plate 43 in a transmission manner. The driving member 44 is used to drive the sliding plate 43 to slide relative to the third connecting plate 41, so that the roller 42 moves relative to the second connecting plate 32.

[0048] Specifically, the third connecting plate 41 is vertically disposed at one end of the second connecting plate 32, the driving member 44 is fixedly disposed on the side of the third connecting plate 41 away from the second connecting plate 32, and the sliding plate 43 is located on the side of the third connecting plate 41 away from the second connecting plate 32. In the first state, the roller 42 is higher than the surface of the second connecting plate 32 away from the first connecting plate 31 along the third direction Z, so that a distance difference is formed between the roller 42 and the surface of the second connecting plate 32 away from the first connecting plate 31, avoiding interference when the roller 42 picks up the diaphragm 6 by the suction cup 33, and ensuring the overall stability; in the second state, the driving member 44 is fixedly disposed on the side of the third connecting plate 41 away from the first connecting plate 31, so that a distance difference is formed between the roller 42 and the surface of the second connecting plate 32 away from the first connecting plate 31, thus avoiding interference when the roller 42 picks up the diaphragm 6 by the suction cup 33, and ensuring the overall stability; in the second state, the driving member 44 is fixedly disposed on the side of the third connecting plate 41 away from the first connecting plate 32, the sliding plate 43 is located on the side of the third connecting plate 41 away from the first connecting plate 32, the sliding plate 43 is located on the side of the third connecting plate 41 away from the first connecting plate 31, thus avoiding interference when the roller 42 picks up the diaphragm 6 by the suction cup 33, thus ensuring the overall stability; in the second state, the driving member 44 is fixedly disposed on the side of the third connecting plate 41 away from the first connecting plate 32, the sliding plate 43 is located on the side of the third connecting plate 41 away from the first connecting plate 32, the sliding plate 43 is located on the side of the third connecting plate 41 away from the first The driving component 44 drives the sliding plate 43 to slide relative to the third connecting plate 41, thereby causing the roller 42 to move relative to the second connecting plate 32 along the second direction Y and protrude from the surface of the second connecting plate 32 away from the first connecting plate 31, so as to roll the applied film 6 to eliminate air bubbles and unevenness. By controlling the position of the roller 42 in different states, not only is interference from the roller 42 when the suction cup 33 picks up the film 6 avoided, but the applied film 6 can also be rolled to eliminate air bubbles and unevenness, ensuring the smoothness of the process sequence and improving the overall stability and production efficiency. Specifically, the driving component 44 is a cylinder.

[0049] Specifically, such as Figure 4 As shown, a slide rail 411 is provided on the side of the third connecting plate 41 away from the second connecting plate 32. A sliding plate 43 is movably mounted on the slide rail 411. Mounting plates 431 extending from the sliding plate 43 are provided on both sides of the sliding plate 43 near the end of the second connecting plate 32. A fixed shaft 432 is provided between the two mounting plates 431, and a roller 42 is sleeved on the fixed shaft 432. This arrangement helps to improve the overall stability and facilitates the rolling of the roller 42.

[0050] Specifically, such as Figure 4 As shown, the robotic vacuum cleaner shell coating device 100 also includes a flipping drive 24 fixedly mounted on the Z-linear module 23. The flipping drive 24 is connected to the first connecting plate 31 and is used to drive the first connecting plate 31 to flip relative to the Z-linear module 23. By setting the flipping drive 24 to drive the adsorption assembly 3 to flip 90° between the first and second states, different process requirements can be met. Specifically, the flipping drive 24 is a 90° flipping cylinder.

[0051] Specifically, such as Figure 4 As shown, the adsorption assembly 3 also includes a reinforcing plate 36 disposed between the first connecting plate 31 and the Z-linear module 23. A flipping drive 24 is connected to the reinforcing plate 36 and is used to drive the reinforcing plate 36 to flip, so that the first connecting plate 31 flips relative to the Z-linear module 23. By providing the reinforcing plate 36, its overall structure can be enhanced, which is beneficial to the overall stability.

[0052] The working principle of the robotic vacuum cleaner shell covering device 100 provided in this embodiment is as follows:

[0053] The X-line module 21, Y-line module 22, and Z-line module 23 adjust the position of the second connecting plate 32 above the membrane 6 placed on the material picking platform (not shown in the figure). Both the second connecting plate 32 and the membrane 6 are in a horizontal state. The suction cup 33 picks up the membrane 6. At this time, the adsorption component 3 is in the first state, in which half of the area of ​​the membrane 6 is coated with a layer of adhesive 7, which is a TPU plastic adhesive layer. Then, the flipping drive component 24 rotates the adsorption component 3 together with the roller assembly 4 90° clockwise relative to the Z-line module 23 to switch to the second state. The X-line module 21, Y-line module 22, and Z-line module 23 control the position of the second connecting plate 32 to be adjusted to the position of the mold 201 on the injection molding device 200. The suction cup 33 attaches the membrane 6 to the mold 201 used to form the shell 5 of the sweeping robot. The side of the membrane 6 with the adhesive layer 7 is set close to the injection port of the injection molding device 200 for easy positioning. Then, the adsorption assembly 3, together with the roller assembly 4, is controlled to move backward along the second direction Y to reserve a rolling distance and avoid interference. At the same time, the drive unit 44 drives the roller 42 to move relative to the second connecting plate 32 along the second direction Y and protrude from the surface of the second connecting plate 32 away from the first connecting plate 31. The Z-linear module 23 controls the adsorption assembly 3, together with the roller assembly 4, to move upward along the third direction Z so that the roller 42 rolls the film 6 attached to the mold 201. After the rolling is completed, the adsorption assembly is moved backward by the flipping drive unit 24. Component 3, together with roller assembly 4, rotates 90° counterclockwise relative to Z-linear module 23, switching to the first state. Simultaneously, drive component 44 drives roller 42 back to its original position, and the robot vacuum cleaner shell coating device 100 resets. At the same time, the left and right mold plates of injection molding device 200 are closed by a mold closing mechanism. The mold 201 on the left mold plate, used to form the robot vacuum cleaner shell 5, closes with the mold on the right mold plate to form the mold cavity of the robot vacuum cleaner shell 5. Then, injection molding is performed to obtain the robot vacuum cleaner shell 5. Figures 7-8 As shown, at this time, the diaphragm 6 is attached to the inside of the robot vacuum cleaner shell 5.

[0054] like Figure 10 As shown, another embodiment of this application also provides a film-coated housing molding apparatus, including an injection molding device 200, on which a mold 201 for molding a robotic vacuum cleaner housing 5 is provided, and further including the robotic vacuum cleaner housing film-coating device 100 provided in the aforementioned embodiments, with the injection molding device 200 disposed opposite to the robotic vacuum cleaner housing film-coating device 100 along the second direction Y. This facilitates the robotic vacuum cleaner housing film-coating device 100 in applying the film 6 onto the mold 201 for molding the robotic vacuum cleaner housing 5, while also reducing the overall space occupied and resulting in a more compact structure.

[0055] By using the robot vacuum cleaner shell coating device 100 and the injection molding device 200 together, a robot vacuum cleaner shell 5 with the film 6 is obtained, which greatly improves the efficiency and accuracy of automatic film application, reduces manual intervention, reduces human operation errors, improves film application quality, increases yield and production efficiency, and reduces production costs.

[0056] Example 2

[0057] The robotic vacuum cleaner shell coating device 100 in this embodiment is largely the same as the robotic vacuum cleaner shell coating device 100 in Embodiment 1, except that the adsorption component 3 is different.

[0058] In this embodiment, the adsorption assembly 3 further includes a plurality of first air nozzles 34 and a plurality of second air nozzles 35. The plurality of first air nozzles 34 are spaced apart along the second direction Y on the side of the first connecting plate 31 away from the Z-line module 23 and located between the two sets of suction cup assemblies. Each set of suction cup assemblies has a plurality of second air nozzles 35 on the side away from the first air nozzles 34. The plurality of second air nozzles 35 are spaced apart along the second direction Y on the side of the first connecting plate 31 away from the Z-line module 23. The second connecting plate 32 has a plurality of second clearance holes 322 spaced apart along the second direction Y on the side facing the first connecting plate 31 and located between the two sets of suction cup assemblies. The holes 322 correspond one-to-one with multiple first air nozzles 34, and each first air nozzle 34 passes through a corresponding second clearance hole 322. The two ends of the second connecting plate 32 facing the first connecting plate 31 are respectively provided with multiple third clearance holes 323 spaced apart along the second direction Y. The multiple third clearance holes 323 correspond one-to-one with multiple second air nozzles 35, and each second air nozzle 35 passes through a corresponding third clearance hole 323. In the first state, the first air nozzles 34 and the second air nozzles 35 are used to remove dust from the diaphragm 6. In the second state, the first air nozzles 34 and the second air nozzles 35 are used to press the diaphragm 6 after it has been applied by air jet.

[0059] Under normal circumstances, dust or powder easily adheres to the diaphragm 6, affecting the product's appearance, yield, and application effect. Therefore, dust removal is necessary before adsorbing the diaphragm 6. Furthermore, during the process of applying the diaphragm 6 with a suction cup and then rolling it, it was found that the application was not tight, leading to wrinkles during subsequent rolling. By setting the first air nozzle 34 and the second air nozzle 35, not only is dust removal of the diaphragm 6 achieved, but pre-coating of the applied diaphragm 6 is also possible, significantly improving the efficiency and cleanliness of automatic film application, further enhancing yield and production efficiency, and reducing production costs.

[0060] Specifically, the first jet nozzle 34 and the second jet nozzle 35 are respectively connected to the jetting device (not shown in the figure).

[0061] Specifically, in the first state, the airflow ejected by the first nozzle 34 is greater than the airflow ejected by the second nozzle 35, and in the second state, the airflow ejected by the first nozzle 34 is less than the airflow ejected by the second nozzle 35.

[0062] Specifically, the first jet nozzle 34 is equipped with a control valve (not shown in the figure). By controlling the opening of the control valve, the airflow size ejected by the first jet nozzle 34 can be adjusted. The second jet nozzle 35 is equipped with a control valve (not shown in the figure). By controlling the opening of the control valve, the airflow size ejected by the second jet nozzle 35 can be adjusted.

[0063] In the first state, the airflow from the first nozzle 34 is controlled to be greater than that from the second nozzle 35, causing dust or particulate matter to diffuse from the center to both sides, resulting in better dust removal. In the second state, because the adhesion of the film 6 on both sides is weaker, if the airflow from the first nozzle 34 and the second nozzle 35 is kept consistent, the edges of the film 6 will not adhere well to the robot vacuum cleaner housing 5. Since the second nozzle 35 is positioned to pre-press the two sides of the film 6 after application, by controlling the airflow from the first nozzle 34 to be less than that from the second nozzle 35 in the second state, the pre-pressing effect is further improved, which further improves the efficiency and cleanliness of automatic film application, while also increasing the yield rate and production efficiency and reducing production costs. By rationally setting the positions of the first jet nozzle 34 and the second jet nozzle 35, as well as the airflow magnitude of the first jet nozzle 34 and the second jet nozzle 35 under different states, it is not only beneficial to the compactness of the structure, but also to further improve the dust removal effect and the pre-coating effect through process timing control, thereby meeting the diversified process requirements, further improving the yield and production efficiency, and reducing production costs.

[0064] The working principle of the robotic vacuum cleaner shell covering device 100 provided in this embodiment is as follows:

[0065] The second connecting plate 32 is adjusted to be above the diaphragm 6 placed on the picking platform using the X-linear module 21, Y-linear module 22, and Z-linear module 23. Both the second connecting plate 32 and the diaphragm 6 are horizontal. First, the first jet nozzle 34 and the second jet nozzle 35 are controlled to eject airflow, with the airflow from the first jet nozzle 34 being greater than that from the second jet nozzle 35, for dust removal. After dust removal, the first jet nozzle 34 and the second jet nozzle 35 are closed, and then the diaphragm 6 is picked up by the suction cup 33. At this time, the adsorption assembly 3 is in the first... In the first state, the adsorption assembly 3 and roller assembly 4 are rotated 90° clockwise relative to the Z linear module 23 by the flipping drive 24, switching to the second state. The X linear module 21, Y linear module 22, and Z linear module 23 control the position of the second connecting plate 32 to be adjusted to the position of the mold 201 on the injection molding device 200. The suction cup 33 attaches the diaphragm 6 to the mold 201 used to form the housing 5 of the sweeping robot. The side of the diaphragm 6 with the adhesive layer 7 is set close to the injection port of the injection molding device 200 for easy positioning. Then, the adsorption assembly 3, together with the roller assembly 4, is controlled to retract along the second direction Y to allow for a rolling distance and avoid interference. The first nozzle 34 and the second nozzle 35 are controlled to eject airflow, wherein the airflow ejected by the first nozzle 34 is less than that ejected by the second nozzle 35. Simultaneously, the drive unit 44 drives the roller 42 to move relative to the second connecting plate 32 along the second direction Y and protrude from the surface of the second connecting plate 32 away from the first connecting plate 31. The Z-linear module 23 controls the adsorption assembly 3, together with the roller assembly 4, to move upward along the third direction Z, so that while the first nozzle 34 and the second nozzle 35 pre-press the film 6 on the mold 201, the roller 42 presses the film 6 adhered to the mold 201. The diaphragm 6 on the mold 201 is synchronously rolled. After rolling, the first air nozzle 34 and the second air nozzle 35 are closed. The adsorption assembly 3 and the roller assembly 4 are rotated 90° counterclockwise relative to the Z-linear module 23 by the flipping drive 24, switching to the first state. At the same time, the drive 44 drives the roller 42 to return to its original position, and the robot vacuum cleaner shell coating device 100 is reset. Simultaneously, the left and right templates of the injection molding device 200 are closed by the mold closing mechanism. The mold 201 on the left template for forming the robot vacuum cleaner shell 5 is closed with the mold on the right template to form the mold cavity of the robot vacuum cleaner shell 5. Then, the injection molding process is performed to obtain the robot vacuum cleaner shell 5. Figures 7-8 As shown, at this time, the diaphragm 6 is attached to the inside of the robot vacuum cleaner shell 5.

[0066] By controlling the airflow of the first jet nozzle 34 and the second jet nozzle 35, not only is the dust removal effect of the diaphragm 6 improved, but the pre-coating effect is also further enhanced, which further improves the efficiency and cleanliness of automatic film application, while also increasing the yield and production efficiency and reducing production costs.

[0067] The film-coated shell forming equipment in this embodiment is the same as the film-coated shell forming equipment in Embodiment 1, and will not be described again.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
