Description

Technical Field

[0001] The present invention relates to the technical field of smart wearable bracelet diaphragm assembly, and in particular to an automatic diaphragm cleaning device. Background Art

[0002] The application of diaphragms in smart wearable bracelets is mainly reflected in the following two scenarios and functions:

[0003] (1) Display technology

[0004] Electronic paper membrane: Electronic paper membrane is a new type of electronic ink display technology. Its main components are polyimide and conductive materials. It is ultra-thin, ultra-light, flexible, and low-power. This membrane is sensitive to light sources and can achieve low-power display. Therefore, it has been widely used in low-power devices such as smart wearable bracelets.

[0005] (2) Waterproof and breathable

[0006] Water-resistant membrane: The smart band's water-resistant membrane is highly waterproof and breathable. This breathability balances internal and external pressures, providing a certain degree of waterproofing. This water-resistant, breathable membrane ensures the band remains waterproof.

[0007] To facilitate the transportation and storage of the diaphragm, the diaphragm is often attached to a roll to form a continuous strip structure, which is more convenient for transportation and storage. In the process of removing and assembling the diaphragm from the roll, it is necessary to use a suction cup to remove the adhered diaphragm. During the removal process, in order to ensure the assembly effect of the diaphragm on the bracelet, the bottom of the diaphragm needs to be blown clean. Due to the toughness of the diaphragm itself, the diaphragm in an adsorbed state is prone to deformation during the blowing and cleaning process. During the deformation process, the adsorption effect of the suction cup on the diaphragm is affected and even the diaphragm may fall off, which is not conducive to the stable self-cleaning operation of the diaphragm during the assembly process.

[0035] Example 1

[0036] See also Figures 1-11 The automatic diaphragm cleaning device shown in the figure includes an operating table 101 and multiple groups of diaphragm bodies 102, and also includes:

[0037] An operating frame 2 is provided above the operating table 101, and the operating frame 2 is supported and installed on the upper end of the operating table 101 by a support seat 3. The operating table 101 is provided with a feeding assembly for feeding the diaphragm body 102 and a taking assembly for taking the diaphragm body 102 after feeding. The operating table 101 is provided with a cleaning assembly for self-cleaning the diaphragm body 102 after taking the material. Two groups of U-shaped covers 9 for blowing air to prevent the diaphragm body 102 from falling off are provided above the diaphragm body 102 during the cleaning process. L-shaped frames 8 are installed on both sides of the operating table 101, and the two groups of U-shaped covers 9 are located between the two groups of L-shaped frames 8. The L-shaped frames 8 are provided with an adjustment assembly for adjusting the positions of the two groups of U-shaped covers 9;

[0038] Preferably, the cleaning assembly includes an air blowing cleaning cover 701 arranged above the operating table 101, two sets of U-shaped covers 9 are located above the air blowing cleaning cover 701, the air blowing cleaning cover 701 and the operating table 101 are fixed by a mounting bracket 702, and an air supply assembly for supplying air to the air blowing cleaning cover 701 and the two sets of U-shaped covers 9 is provided on the operating table 101;

[0039] It should be noted here that: through the mutual cooperation of the feeding component, the picking component, the cleaning component and the two sets of U-shaped covers 9, the diaphragm body 102 can be fed, picked and blown clean quickly and efficiently, which is convenient for the subsequent high-quality assembly of the diaphragm body 102. In addition, during the blowing cleaning process, the gas blown out from the two sets of U-shaped covers 9 generates a thrust on the upper and surrounding parts of the diaphragm body 102 during the adsorption cleaning process. Through the thrust action, the diaphragm body 102 is prevented from being deformed during the blowing cleaning process, which affects the adsorption stability of the diaphragm body 102.

[0040] Preferably, the feeding assembly includes an operating frame 401 fixed to the upper end of the operating table 101, and a discharge roller 402 and a winding roller 403 are rotatably connected to the operating frame 401. A tape 404 is wound between the discharge roller 402 and the winding roller 403. Each group of diaphragm bodies 102 is evenly adhered to the surface of the tape 404 by means of colloid. The tape 404 passes through the operating frame 2, and the operating frame 2 is provided with a support assembly for supporting the tape 404.

[0041] It should be noted here that: the roll tape 404 with the film body 102 adhered to it is placed on the discharge roller 402. After the placement is completed, one end of the roll tape 404 is passed through the operating frame 2 and one end of the roll tape 404 is fixed to the outer side of the winding roller 403. In the process of the roll tape 404 passing through the operating frame 2, the support roller 504 and the support plate 502 are respectively supported by the outer side and the inner side of the roll tape 404, so as to facilitate the subsequent stable transportation of the roll tape 404. After installation and connection, the roll tape 404 is transported between the discharge roller 402, the winding roller 403 and the operating frame 2 through the coordinated rotation of the discharge roller 402 and the winding roller 403.

[0042] Preferably, the support assembly includes a strip frame 501 disposed inside the operating frame 2 and a support plate 502 for supporting against the inner side of the roll belt 404. The strip frame 501 is fixed inside the operating frame 2. A driving member for driving the support plate 502 to extend and retract is provided on the strip frame 501. The upper end of the operating frame 2 is rotatably connected to a support roller 504 for supporting against the outer side of the conveyed roll belt 404.

[0043] It should be noted here that: one end of the tape 404 is passed through the operating frame 2 and one end of the tape 404 is fixed to the outside of the winding roller 403. In the process of the tape 404 passing through the operating frame 2, the support roller 504 and the support plate 502 are respectively supported against the outside and inside of the tape 404, so as to facilitate the subsequent stable transportation of the tape 404.

[0044] Preferably, the driving member is a transplanting cylinder 503, which is mounted on the strip frame 501, and the output end of the transplanting cylinder 503 is fixed to one end of the support plate 502;

[0045] It should be noted here that the support plate 502 can be driven to extend and retract by the transfer cylinder 503. By extending and retracting the support plate 502, the belt 404 can be controlled to be in a tight or relaxed state, which further facilitates the transportation of the auxiliary belt 404 and the removal of the diaphragm body 102.

[0046] Preferably, the material picking assembly includes a robotic arm 601 disposed on one side of the operating table 101, a driving end of the robotic arm 601 is fixed with an operating cylinder 602, a diaphragm clamping claw 603 is fixed to the outside of the operating cylinder 602, a suction cup 604 for adsorbing the diaphragm body 102 is installed on the inside of the diaphragm clamping claw 603, and a suction fan for extracting pressure from the suction cup 604 is installed inside the operating cylinder 602;

[0047] It should be noted here that: in the process of using the material picking assembly to remove the diaphragm body 102 adhered to the web 404, the suction cup 604 at the front end of the diaphragm clamp 603 is pressed against and adsorbed by the diaphragm body 102 to be picked up on the web 404 through the movement of the operating cylinder 602. After the diaphragm body 102 is pressed against and adsorbed, the support plate 502 is driven to shrink by the transplanting cylinder 503. At this time, the diaphragm body 102 is adsorbed by the suction cup 604, so that the diaphragm body 102 to be picked up is in a suspended state. Then, the diaphragm body 102 is separated from the web 404 by the movement and driving of the operating cylinder 602 and the adsorption of the suction cup 604 and the diaphragm body 102.

[0048] Preferably, the diaphragm clamping jaws 603 are provided with multiple groups on the outside of the operating cylinder 602;

[0049] It should be noted that: multiple groups of diaphragm clamps 603 can be used to perform material removal operations on multiple groups of diaphragm bodies 102.

[0050] Preferably, a visual module 605 is installed at the front end of the operating cylinder 602 for identifying the diaphragm body 102 during the material removal process;

[0051] It should be noted that the visual module 605 facilitates the identification and determination of the position of the diaphragm body 102;

[0052] It is worth noting here that the visual module 605 is generally composed of components such as an image sensor, a lens, and a processor. Its working principle and working method are regarded as conventional technical means in this application and will not be elaborated on here.

[0053] Preferably, the air supply assembly includes an organ hose 1002 installed between the U-shaped cover 9 and the air blowing cleaning cover 701, and a blowing fan 1001 is installed on the upper end of the operating table 101. The two sets of organ hoses 1002 are connected to each other through a connecting hose 1003, and the connecting hose 1003 is installed in communication with the air outlet end of the blowing fan 1001;

[0054] It should be noted here that: through the blowing effect of the blowing fan 1001 and the communication effect of the connecting hose 1003 and the accordion hose 1002, air can be supplied to the U-shaped cover 9 and the blowing cleaning cover 701 at the same time.

[0055] Preferably, the adjustment assembly includes a transmission plate 1101 fixed to one side of the two sets of U-shaped covers 9, a double-headed screw 1102 is rotatably connected between the two sets of L-shaped frames 8, and the threads at both ends of the double-headed screw 1102 are arranged in opposite directions, the two sets of transmission plates 1101 are respectively engaged with the two ends of the double-headed screw 1102, a driving motor 1103 for driving the double-headed screw 1102 is installed on the L-shaped frame 8, a guide rod 1104 is fixed between the two sets of L-shaped frames 8, and the two sets of transmission plates 1101 are slidably connected to the guide rod 1104;

[0056] It should be noted here that: the double-headed screw 1102 is driven to rotate by driving the motor 1103. Since the threads at both ends of the double-headed screw 1102 are set in opposite directions, during the rotation of the double-headed screw 1102, the two sets of transmission plates 1101 and the two ends of the double-headed screw 1102 are mutually engaged and driven by the guide rod 1104 on the transmission plate 1101. The two sets of transmission plates 1101 and the U-shaped cover 9 after being subjected to force move closer to or away from each other, thereby adjusting the distance between the two sets of U-shaped covers 9.

[0057] In this solution: A diaphragm automatic cleaning device includes the following working steps:

[0058] During the cleaning and assembly process of the diaphragm body 102, the roll 404 with the diaphragm body 102 adhered thereto is sleeved on the discharge roller 402. After the sleeve is completed, one end of the roll 404 is passed through the operation frame 2 and one end of the roll 404 is fixed to the outer side of the take-up roller 403. During the process of the roll 404 passing through the operation frame 2, the support roller 504 and the support plate 502 are respectively supported against the outer side and the inner side of the roll 404, which is convenient for the subsequent stable transportation of the roll 404. After installation and connection, the discharge roller 402 and the take-up roller 403 are rotated in coordination, so that the roll 404 is transported between the discharge roller 402, the take-up roller 403 and the operation frame 2. During the transportation process, the diaphragm body 102 adhered to the roll 404 is removed in sequence by the material taking component.

[0059] In the process of using the material taking component to remove the diaphragm body 102 adhered to the roll 404, the mechanical arm 601 drives the operating cylinder 602 to move. During the movement, the suction cup 604 used for adsorption on the diaphragm clamp 603 is first placed above the air blowing cleaning cover 701. The air supply function of the air supply component cooperates with the air discharge function of the air blowing cleaning cover 701 to pre-blow and clean the surface of the suction cup 604 used for adsorption on the diaphragm clamp 603, which is convenient for subsequent more stable film cleaning. The sheet body 102 is subjected to the suction and material picking operation. After the suction cup 604 is pre-cleaned, the suction cup 604 at the front end of the diaphragm clamp 603 is moved to abut against and adsorb the diaphragm body 102 to be picked up on the tape 404. After the diaphragm body 102 is abutted and adsorbed, the support plate 502 is driven to shrink by the transfer cylinder 503. At this time, the suction cup 604 adsorbs the diaphragm body 102, so that the diaphragm body 102 to be picked up is in a suspended state (see Figure 6 ), and then by the moving driving action of the operating cylinder 602 and the adsorption action of the suction cup 604 and the diaphragm body 102, the adsorbed diaphragm body 102 is separated from the roll 404, and the diaphragm body 102 is removed;

[0060] After the diaphragm body 102 is taken out, the mechanical arm 601 moves the operating cylinder 602 so that the adsorbed diaphragm body 102 is placed above the air cleaning cover 701. After the movement is completed, the two sets of U-shaped covers 9 are driven to approach each other through the adjustment component so that the two sets of U-shaped covers 9 are placed on both sides of the diaphragm clamping claw 603 in a sleeve state (see Figure 10), after the position adjustment of the two groups of U-shaped covers 9 is completed, air is supplied to the air blowing cleaning cover 701 and the two groups of U-shaped covers 9 through the air supply component. During the air supply process, the gas blown out from the air blowing cleaning cover 701 blows and cleans the surface of the diaphragm body 102 after adsorption and material removal, which is convenient for the high-quality assembly and processing of the diaphragm body 102 after material removal, and the gas blown out from the two groups of U-shaped covers 9 generates a thrust on the four sides above the diaphragm body 102 during the adsorption and cleaning process. Through the thrust action, the diaphragm body 102 is prevented from being deformed during the process of being blown and cleaned, which affects the adsorption stability of the diaphragm body 102, and further facilitates the stable self-cleaning operation of the diaphragm body 102 during the assembly process. In addition, during the air blowing protection process, the blowing force of the U-shaped cover 9 on the diaphragm body 102 is less than the blowing force of the air blowing cleaning cover 701 on the diaphragm body 102 (the magnitude of the blowing force can be controlled by the air outlet aperture and the length of the pipeline). Through force control, the diaphragm body 102 is prevented from separating from the suction cup 604.
