Description

Technical Field

[0001] This invention belongs to the field of surface cleaning technology, and specifically relates to a thin film surface cleaning mechanism for inspection machines. Background Technology

[0002] Inspection machines play a crucial role in the film production process, saving significant costs in inspection. They primarily use a vision inspection unit (vision camera) to inspect the film during transport (a high-brightness LED linear focused cold light source is positioned in front of the vision camera for backlighting, with the transported film located between the two). However, impurities such as dust, particles, and insects may appear in certain areas of the film, requiring timely removal.

[0003] In existing technologies, methods for removing impurities adsorbed on film surfaces typically include air blowing and adhesive rollers. Air blowing involves placing fans on both sides of the conveyed film and blowing air at an angle towards the film to remove adsorbed impurities. However, this method cannot control the direction of falling impurities, and the film vibrates due to the wind, easily leading to more serious quality problems, making it impractical. Adhesive rollers involve placing rollers with adhesion functions on one or both sides of the film. Impurities are removed through contact with the film. However, this method easily results in adhesive residue from the rollers being applied to the film, which cannot be removed and also leads to film quality problems, making it impractical as well. Summary of the Invention

[0004] This invention provides a film surface cleaning mechanism for inspection machines, which aims to solve the problem that existing methods for removing impurities adsorbed on the film surface during the inspection process of films are not practical.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a film surface cleaning mechanism for an inspection machine, including an auxiliary mounting frame, a cleaning component, and an adjustment component;

[0006] The auxiliary mounting bracket is used to be mounted on the body of the inspection machine; the auxiliary mounting bracket has a film-passing cavity for the film to pass through;

[0007] The cleaning assembly includes two components, both of which are slidably mounted on the auxiliary mounting bracket and located on opposite sides of the film. Each cleaning assembly has a contact surface that is parallel to and faces the film. The two cleaning assemblies are used to move relative to each other to clamp the film together and clean impurities adsorbed on one side of the film.

[0008] The adjustment component is used to drive the two cleaning components to move relative to each other or in opposite directions.

[0009] In one possible implementation, the spacing between the two cleaning components is perpendicular to the direction of film transfer.

[0010] In one possible implementation, each of the cleaning components includes a rodless cylinder and a cleaning structure;

[0011] The rodless cylinder is disposed in the film-moving cavity and is arranged along the width direction of the film. Both ends of the rodless cylinder are slidably connected to the auxiliary mounting frame, and the rodless cylinder has a slider portion.

[0012] The cleaning structure is disposed on the slider portion and is used to move to the position of the film to be cleaned and then contact the film to remove impurities adsorbed in the position of the film to be cleaned.

[0013] In one possible implementation, the cleaning structure includes a fixed box, a partition, a blower, a movable baffle, and an electric push rod;

[0014] The fixing box is fixed on the slider part. The end of the fixing box away from the slider part is provided with a side wall surface that is parallel to the film. The side wall surface is the contact surface. The fixing box has a receiving cavity and an opening communicating with the receiving cavity is provided on the contact surface. The side of the fixing box away from the contact surface is provided with an outlet.

[0015] The partition plate is fixed in the accommodating cavity and is arranged along the orientation of the opening. The partition plate divides the accommodating cavity into an air inlet cavity and a cleaning cavity communicating with the opening. The end of the partition plate near the opening is provided with a communication port communicating with the air inlet cavity and the cleaning cavity.

[0016] The blower is fixed on the fixed box, and the air outlet of the blower is connected to the air inlet provided on the side wall of the air inlet chamber.

[0017] The movable baffle is slidably disposed in the cleaning chamber along the orientation of the opening and in sliding contact with the partition plate. The movable baffle is provided with a sealing block adapted to the opening.

[0018] The electric push rod is fixed on the fixed box and connected to the movable baffle, and is used to drive the movable baffle to move back and forth along the direction of the opening;

[0019] Wherein, after the electric push rod drives the movable baffle to move away from the opening, the air sent in by the air inlet cavity enters between the sealing block and the opening through the connecting port to clean the impurities on the surface of the film, and carries the impurities from the end of the movable baffle away from the partition plate to the space behind the movable baffle, and is introduced through the outlet.

[0020] In one possible implementation, the cleaning structure further includes a filter screen disposed at the opening.

[0021] In one possible implementation, each rodless cylinder is provided with a limiting slider at both ends, and a corresponding elongated sliding opening is provided on the auxiliary mounting bracket for the limiting slider to slide and connect.

[0022] In one possible implementation, there are two adjustment components, which are respectively disposed on both sides of the rodless cylinder, and each adjustment component includes a telescopic structure and a connecting rod.

[0023] The telescopic structure is arranged along the transmission direction of the film and has a fixed end and a telescopic end. The fixed end of the telescopic structure is fixed on the auxiliary mounting frame.

[0024] The connecting rod is provided in two parts, and the two connecting rods are respectively configured to correspond one-to-one with the two rodless cylinders. One end of each connecting rod is hinged to the limiting slider on the corresponding rodless cylinder, and the other end is hinged to the telescopic end of the telescopic structure.

[0025] In one possible implementation, each of the limiting sliders is provided with a hinge portion for the connecting rod to hinge.

[0026] In this implementation, two cleaning components are provided, distributed on both sides of the film, to clean impurities adsorbed on the two side surfaces of the film, ensuring effective cleaning. The contact surfaces of the two cleaning components clamp the film between them, preventing vibration during the cleaning process and ensuring film quality. Furthermore, the two cleaning components can move relative to each other or in opposite directions under the action of an adjusting component, ensuring disengagement from the film after cleaning, preventing marks and secondary damage, and maintaining film quality. The film surface cleaning mechanism for inspection machines provided by this implementation ensures film stability during impurity removal, prevents recurrence of quality problems, guarantees film production quality, and is highly practical.

[0036] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0037] Please refer to the following: Figure 1 and Figure 2 The following describes the film surface cleaning mechanism for an inspection machine provided by the present invention. The film surface cleaning mechanism for an inspection machine includes an auxiliary mounting frame 10, cleaning components 20, and an adjusting component 30. The auxiliary mounting frame 10 can be mounted on the body of the inspection machine. The auxiliary mounting frame 10 has a film-passing cavity for the film 40 to pass through. Two cleaning components 20 are provided, each slidably mounted on the auxiliary mounting frame 10 and located on opposite sides of the film 40. Each cleaning component 20 has a contact surface 2211 parallel to and facing the film 40. The two cleaning components 20 can move relative to each other to clamp the film 40 and clean impurities adsorbed on one side of the film 40. The adjusting component 30 can drive the two cleaning components 20 to move relative to each other or in opposite directions.

[0038] The working principle of the film surface cleaning mechanism for the inspection machine provided in this embodiment is as follows: After the film 40 passes through the vision detection unit during the inspection and transfer process and is detected by the vision detection unit to have impurities adsorbed on its surface, under the control of the inspection machine control system, the part with adsorbed impurities moves to the corresponding position between the two cleaning components 20. The adjusting component 30 drives the two cleaning components 20 to move relative to each other so that the two contact surfaces 2211 clamp the film 40 therebetween. Then, the two cleaning components 20 clean the impurities adsorbed on the film 40. After cleaning, the adjusting component 30 drives the two cleaning components 20 to move in opposite directions to detach from the film 40. At this time, the inspection machine continues to work and the film 40 continues to be transferred.

[0039] The film surface cleaning mechanism for inspection machines provided in this embodiment, compared with the prior art, has two cleaning components 20, distributed on both sides of the film 40, which can clean impurities adsorbed on the two side surfaces of the film 40, ensuring the cleaning effect of the film 40. The contact surfaces 2211 on the two cleaning components 20 can clamp the film 40, which can prevent the film 40 from vibrating during the cleaning process and ensure the quality of the film 40. Moreover, the two cleaning components 20 can also move relative to each other or in opposite directions under the drive of the adjusting component 30, ensuring that they disengage from the film 40 after cleaning, avoiding leaving marks on the film 40, preventing secondary damage to the film 40, and ensuring the quality of the film 40. The film surface cleaning mechanism for inspection machines provided in this embodiment can ensure the stability of the film 40 during the cleaning process, and can also prevent the film 40 from having quality problems again, ensuring the production quality of the film 40, and is highly practical.

[0040] In some embodiments, the cleaning component 20 described above may employ, for example... Figure 2 The structure shown. See also Figure 2 The two cleaning components 20 are spaced perpendicularly to the transfer direction of the film 40. This structure ensures that the two contact surfaces 2211 are opposite each other, avoids misalignment of the two contact surfaces 2211, and thus ensures the clamping area when clamping the film 40, thereby expanding the cleaning range.

[0041] In some embodiments, the cleaning component 20 described above may employ, for example... Figures 1 to 2 The structure shown. See also Figures 1 to 2 Each cleaning component 20 includes a rodless cylinder 21 and a cleaning structure 22. The rodless cylinder 21 is disposed in the film-carrying chamber and is arranged along the width direction of the film 40. Both ends of the rodless cylinder 21 are slidably connected to the auxiliary mounting bracket 10, and the rodless cylinder 21 has a slider portion. The cleaning structure 22 is disposed on the slider portion and can move to the position of the film 40 to be cleaned and contact the film 40 to remove impurities adsorbed in the position of the film 40 to be cleaned.

[0042] The rodless cylinder 21 ensures that the cleaning structure 22 moves along the width of the film 40, thereby ensuring that the cleaning structure 22 corresponds to the area on the film 40 where impurities are adsorbed, thus guaranteeing the removal of impurities. The rodless cylinder 21 has a simple structure and is easy to control.

[0043] It should be noted that the sliders on the two rodless cylinders 21 slide synchronously, meaning that the two cleaning structures 22 need to be in the same position in the width direction of the film 40 during the movement of the two cleaning structures 22.

[0044] In some embodiments, the cleaning structure 22 described above may employ, for example... Figure 3 The structure shown. See also Figure 3 The cleaning structure 22 includes a fixed box 221, a partition plate 222, a blower 223, a movable baffle 224, and an electric push rod 225.

[0045] A fixed housing 221 is fixed to the slider section. The end of the fixed housing 221 away from the slider section has a side wall parallel to the film 40, which serves as a contact surface 2211. The fixed housing 221 has a receiving cavity, and an opening 227 communicating with the receiving cavity is provided on the contact surface 2211. An outlet is provided on the side of the fixed housing 221 away from the contact surface 2211. A partition plate 222 is fixed in the receiving cavity and arranged along the orientation of the opening 227. The partition plate 222 divides the receiving cavity into an air inlet cavity 229 and a cleaning cavity communicating with the opening 227. The end of the partition plate 222 near the opening 227 has a connecting port communicating with the air inlet cavity 229 and the cleaning cavity. A blower 223 is fixed to the fixed housing 221, and the outlet of the blower 223 communicates with an air inlet provided on the side wall of the air inlet cavity 229. The movable baffle 224 is slidably disposed in the cleaning chamber along the orientation of the opening 227 and is in slidable contact with the partition plate 222. The movable baffle 224 is provided with a sealing block adapted to the opening 227. The electric push rod 225 is fixed on the fixed box 221 and connected to the movable baffle 224, and can drive the movable baffle 224 to reciprocate along the direction of the opening 227.

[0046] After the electric push rod 225 moves the movable baffle 224 away from the opening 227, the air sent in by the air inlet 229 enters between the sealing block and the opening 227 through the connecting port to clean the impurities on the surface of the membrane 40. The air carrying the impurities flows from the end of the movable baffle 224 away from the partition plate 222 to the space behind the movable baffle 224 and is introduced through the outlet.

[0047] In this embodiment, the two cleaning structures 22 need to work simultaneously. Assume the two outer surfaces of the film 40 are the front and back sides, respectively, with each side corresponding to a cleaning structure 22. When the visual inspection unit detects impurities adsorbed in a certain area of ​​the front side, the film 40 moves, transferring that area to the location of the rodless cylinder 21. At this point, the two rodless cylinders 21 respectively drive the two cleaning structures 22 to move to that area, and the two cleaning structures 22 move relative to each other, clamping the film 40 within them. Because there are impurities on the front side, in the cleaning structure 22 corresponding to the back side of the film 40, the electric push rod 225 pushes the moving baffle 224, causing the sealing block 228 to block the opening 227, and the outward-facing end of the sealing block 228 moves to be flush with the contact surface 2211. This cleaning structure 22 only provides a flat surface that can contact the film 40. In the cleaning structure 22 corresponding to the front of the film 40, the movable baffle 224 moves away from the film 40 under the drive of the electric push rod 225, so that a gap appears between the sealing block 228 and the film 40. Since the opening 227 is set on the side wall of the fixed box 221, the opening 227 has a certain thickness. At this time, an air passage will appear in the fixed box 221. The air passage includes the air inlet chamber 229, the connecting port, the gap between the sealing block 228 and the film 40 at the opening 227, the gap between the end of the movable baffle 224 away from the partition plate 222 and the side wall of the accommodating cavity, and the space on the back of the movable baffle 224. Finally, the air passage is connected to the outlet.

[0048] In this embodiment, when the air blown in by the blower 223 enters the gap between the sealing block 228 and the membrane 40, it blows away and carries away the impurities adsorbed on the front side of the membrane 40. Because it is abutted by the cleaning structure 22 on the back side of the membrane 40, the membrane 40 located in the opening 227 area can be kept flat, preventing the membrane 40 from vibrating or being stretched by the wind, thus ensuring the quality of the membrane 40. Finally, the impurities are carried by the wind to the back space of the movable baffle 224.

[0049] In addition, to ensure a tight fit between the sealing block 228 and the opening 227, the side view section of the opening 227 can be an isosceles trapezoidal structure, as shown in [reference needed]. Figure 3 This structure ensures that the sealing block 228 is limited, preventing the outward-facing end of the sealing block 228 from protruding from the contact surface 2211. In addition, this structure also ensures the flow of air.

[0050] It should be noted that the clamping of the film 40 by the two contact surfaces 2211 does not require compression; the film 40 only needs to be clamped between them.

[0051] It should be noted that the back of the movable baffle 224, that is, the side of the movable baffle 224 away from the opening 227, and the side of the movable baffle 224 closer to the opening 227, is the head.

[0052] In some embodiments, the cleaning structure 22 described above may employ, for example... Figure 4 The structure shown. See also Figure 4 The cleaning structure 22 also includes a filter screen 226, which is disposed at the opening 227. The filter screen 226 is designed to intercept impurities so that they remain in the space behind the movable baffle 224, preventing impurities from floating out of the opening 227 and continuing to fall onto the membrane 40.

[0053] It should be noted that the fixed box 221 is equipped with a sealed door for cleaning internal impurities.

[0054] In some embodiments, the rodless cylinder 21 described above can be as follows: Figure 1 The structure shown. See also Figure 1 Each rodless cylinder 21 has a limit slider at both ends, and a corresponding long strip slide 11 for sliding connection of the limit slider is provided on the auxiliary mounting bracket 10.

[0055] The limiting slider and the matching elongated sliding opening 11 can ensure the linear sliding of the two rodless cylinders 21, thereby ensuring that they move relative to each other or move in opposite directions.

[0056] In some embodiments, the adjustment component 30 may employ, for example... Figure 1 The structure shown. See also Figure 1 Two adjustment components 30 are respectively arranged on both sides of the rodless cylinder 21. Each adjustment component 30 includes a telescopic structure 31 and a connecting rod 32. The telescopic structure 31 is arranged along the transmission direction of the diaphragm 40 and has a fixed end and a telescopic end. The fixed end of the telescopic structure 31 is fixed on the auxiliary mounting frame 10. There are two connecting rods 32, which are respectively arranged one-to-one with the two rodless cylinders 21. One end of each connecting rod 32 is hinged to the limit slider on the corresponding rodless cylinder 21, and the other end is hinged to the telescopic end of the telescopic structure 31.

[0057] The telescopic structure 31 drives two connecting rods 32, which can simultaneously pull two rodless cylinders 21 to move relative to each other or in opposite directions, thereby ensuring that the cleaning structure 22 comes into contact with or leaves the membrane 40.

[0058] In some embodiments, the aforementioned limiting slider can be as follows: Figure 1 The structure shown. See also Figure 1 Each limit slider is provided with a hinge part for the connecting rod 32 to hinge, and the hinge part can ensure the rotational connection of the pull rod.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
