Description

Technical Field

[0001] This utility model relates to a sheet bonding device. Background Technology

[0002] Many current devices and apparatuses contain components that require the attachment of sheet-like materials. For example, a microphone head needs to have an acoustic damping sheet installed, which is usually a mesh, to improve the microphone's performance.

[0003] These mesh-like acoustic damping sheets are often thin and have a small diameter (when they are circular), making them very flexible and easily deformable components. Furthermore, acoustic damping sheets often need to be attached to other components, so they usually also have adhesive on them.

[0004] The current installation process involves workers manually picking up the acoustic damping sheet and attaching it to the relevant components. However, this manual operation makes it difficult to guarantee the installation accuracy of the acoustic damping sheet. For example, manual operation can cause unnecessary deformation of the acoustic damping sheet, and the adhesive on the sheet can cause it to stick to the worker's hands. Therefore, it is difficult to guarantee the accuracy and efficiency of the acoustic damping sheet installation and positioning.

[0005] Therefore, there is a need in the art for a technical solution that can ensure the accurate positioning and installation of sheet materials (e.g., acoustic damping sheets). Utility Model Content

[0006] In response to the problems and needs mentioned above, this disclosure proposes a novel technical solution that solves the aforementioned problems and brings about other technical effects by adopting the following technical features.

[0007] This utility model provides a sheet attaching device for attaching sheet material to a target component, comprising: a sheet material placement station; a target component placement station; a first sheet material positioning device configured to move to the sheet material placement station and acquire a first position signal of the sheet material at the sheet material placement station; and a sheet material picking device configured to move and pick up the sheet material according to the first position signal of the sheet material, wherein the sheet material picking device is further configured to move to the target component placement station and attach the sheet material to the target component at the target component placement station.

[0008] Preferably, the sheet bonding equipment further includes a three-dimensional moving system having a mounting plate, and the first sheet positioning device and the sheet picking device are mounted on the mounting plate, the three-dimensional moving system being configured to move the mounting plate along the three coordinate axes of a Cartesian coordinate system defined for the sheet bonding equipment.

[0009] Preferably, the first sheet positioning device includes a first camera to acquire a first image of the sheet on the sheet placement station.

[0010] Preferably, the sheet picking device is configured to be moved to an intermediate position by a three-dimensional moving system, and the sheet attaching device further includes a second sheet positioning device, which is configured to acquire a second position signal of the sheet on the sheet picking device at the intermediate position; and the sheet picking device is further configured to move from the intermediate position to the target component placement station according to the second position signal, and attach the sheet to the target component at the target component placement station.

[0011] Preferably, the second sheet positioning device includes a second camera to acquire a second image of the sheet.

[0012] Preferably, the sheet attaching device further includes: a first light source, which is associated with the first camera and can illuminate the sheet on the sheet placement station; and a second light source, which is associated with the second camera and can illuminate the sheet on the sheet picking device located at the intermediate position.

[0013] Preferably, the first light source is mounted on the mounting plate and positioned directly below the first camera, and has a housing and a light-emitting device installed inside the housing. The housing of the first light source has a first transparent component positioned within the field of view of the first camera, so that the first camera can obtain a first image of the sheet through the first transparent component. The second light source is positioned directly above the second camera and has a housing and a light-emitting device installed inside the housing. The housing of the second light source has a second transparent component positioned within the field of view of the second camera.

[0014] Preferably, the sheet bonding equipment includes a substrate, a sheet placement station, a target component placement station, a three-dimensional moving system, and a second light source disposed on the upper surface of the substrate.

[0015] Preferably, the second camera is disposed below the substrate, and the substrate includes a third transparent component disposed within the field of view of the second camera, so that the second camera can obtain a second image of the sheet through the second transparent component and the third transparent component.

[0016] Preferably, the sheet loading station includes an automatic sheet roll peeling machine and a loading table for carrying the sheets peeled off from the automatic sheet roll peeling machine.

[0017] This invention's equipment can replace manual application work by workers, avoiding unnecessary deformation of the sheet material caused by manual operation. Furthermore, this equipment allows for accurate positioning and picking of the sheet material during the picking stage, and accurate sheet application can typically be performed immediately after the sheet is accurately picked up.

[0023] This invention provides a sheet attaching device for attaching sheet material to a target component. For example, an acoustic damping sheet can be mounted onto a relevant component in the head of a microphone.

[0024] like Figure 1-2 As shown in the preferred embodiment, the sheet bonding equipment includes: a sheet placement station 1; a target component placement station 2; a first sheet positioning device 31, configured to move to the sheet placement station 1 and acquire a first position signal of the sheet on the sheet placement station 1; and a sheet picking device 4, configured to move and pick up the sheet according to the first position signal of the sheet, and the sheet picking device 4 is further configured to move to the target component placement station 2 and attach the sheet to the target component on the target component placement station 2.

[0025] It should be understood that the first sheet positioning device 31 can be implemented by any suitable means or device, such as a device based on vision, infrared, ultrasound, or electromagnetic sensing and positioning, as long as it can determine the accurate position of the sheet so that the sheet picking device 4 can pick up the sheet. The sheet picking device 4 can be, for example, a vacuum nozzle or any other suitable picking device (e.g., a magnetic picking device, an electrostatic picking device, etc.). The first sheet positioning device 31 and the sheet picking device 4 can be moved by any suitable individual drive system or integrated drive system (e.g., the three-dimensional motion system 5 described later). The movement and operation of the various components, devices, systems, etc. described above and later can be controlled by some individual controllers or by an integrated control system, the composition of which will not be described further herein.

[0026] The equipment of this invention can replace manual application work by workers, avoiding unnecessary deformation of the sheet caused by manual operation. Furthermore, this equipment allows for accurate positioning and picking of the sheet during the sheet picking stage, and accurate sheet application can usually be performed immediately after the sheet is accurately picked up. In other words, this invention overcomes the problems of potential sheet deformation and inaccurate positioning during the sheet picking stage through the first sheet positioning device 31 and the sheet picking device 4.

[0027] Preferably, the sheet placement station 1 may include an automatic sheet roll peeling machine 11 and a placement table 12 for carrying the sheets peeled from the automatic sheet roll peeling machine 11. Taking acoustic resist sheets as an example, the automatic peeling machine 11 peels one or more rows of acoustic resist sheets (not shown) from a perforated material roll 13 and conveys them to the placement table 12. The placement table 12 may also include, for example, a material that is not sticky to the adhesive on the acoustic resist sheets to facilitate subsequent pick-up operations. Furthermore, the first sheet positioning device 31 can position each of the one or more rows of acoustic resist sheets on the placement table 12, and the sheet pick-up device 4 accurately picks up the corresponding acoustic resist sheet according to the corresponding positioning signal.

[0028] Preferably, the sheet attaching device may further include a three-dimensional moving system 5. The three-dimensional moving system 5 may also have a mounting plate 51, and the first sheet positioning device 31 and the sheet picking device 4 are mounted on the mounting plate 51, so that the first sheet positioning device 31 and the sheet picking device 4 can move together with the mounting plate 5, which further simplifies the movement operation of the two.

[0029] Specifically, the three-dimensional moving system 5 is configured to move the mounting plate 51 along the three coordinate axes (XYZ) of a Cartesian coordinate system defined for the sheet attachment equipment. This three-dimensional moving system 5 is, for example, a moving system driven by a cylinder or hydraulic cylinder, and includes necessary guide rails, supports, etc. (shown in the figures but not labeled).

[0030] Preferably, the first sheet positioning device 31 includes a first camera (not marked) to acquire a first image of the sheet on the sheet placement station 1. That is, the first sheet positioning device 31 is a visual positioning device, and the acquired first image of the sheet can be processed to obtain a first position signal of the sheet (e.g., by determining the position of a feature portion of the sheet, the edge position of the sheet, the geometric center position of the sheet, etc.). This positioning process can be implemented in any suitable manner, for example, by a processor in the control system as described above.

[0031] On the other hand, after the sheet is picked up by the sheet picking device 4, its position may shift or deviate due to various reasons. That is, although the sheet has been accurately positioned by the first sheet positioning device 31, it may not be in an ideal position after being picked up by the sheet picking device 4. For example, if the sheet picking device 4 is configured as a vacuum nozzle, due to airflow disturbances, the position of the sheet picked up each time may not be completely consistent or ideal. Therefore, in order to further improve the sheet bonding accuracy, this utility model also proposes to perform secondary positioning on the sheet that has been picked up by the sheet picking device 4 before performing the sheet bonding operation.

[0032] Specifically, the sheet picking device 4 is also configured to be moved to an intermediate position by the three-dimensional moving system 5. The sheet attaching device also includes a second sheet positioning device 32, which is configured to acquire a second position signal of the sheet on the sheet picking device 4 at the intermediate position. For example, the sheet picking device 4 can remain at the intermediate position for a period of time so that the second sheet positioning device 32 has sufficient time to acquire the second position signal of the sheet. Furthermore, the sheet picking device 4 is also configured to move from the intermediate position to the target component placement station 2 according to the second position signal and attach the sheet to the target component on the target component placement station 2.

[0033] By providing an additional second sheet positioning device 32, the position of the sheet on the sheet picking device 4 can be accurately repositioned before the bonding operation, thereby guiding the sheet picking device 4 to move more accurately to the target component placement station 2 and perform the bonding operation. Thus, the accuracy of the sheet bonding operation can be greatly improved after two accurate positioning operations by the first and second sheet positioning devices 32.

[0034] It should be understood that the second sheet positioning device 32 may be similar to the first sheet positioning device 31 and may be implemented by any suitable means or means, such as a device based on vision, infrared, ultrasound or electromagnetic sensing and positioning.

[0035] Preferably, the second sheet positioning device 32 may include a second camera to acquire a second image of the sheet. That is, the second sheet positioning device 32 is also a visual positioning device, and the acquired second image of the sheet can be processed to obtain a second position signal of the sheet. This processing can be implemented in any suitable manner, for example, by a processor in the control system as described above.

[0036] Furthermore, since sheet bonding equipment is typically installed in poorly lit factory environments, the poor lighting conditions of the first and second sheet positioning devices 31 and 32, which are implemented as cameras, may affect the quality of the acquired images, thereby impacting the accuracy of the relevant position signals. Therefore, this invention proposes that the sheet bonding equipment may further include: a first light source 61, which is associated with the first camera and illuminates the sheet on the sheet placement station 1; and a second light source 62, which is associated with the second camera and illuminates the sheet on the sheet picking device 4 located in the middle position.

[0037] It should be understood that the “associated settings” mentioned above refer to the fact that the position of the light source can be set relatively flexibly. For example, it can be set in a suitable position around the relevant camera, at a distance that is far or close to the camera, or even an LED light integrated with the camera, as long as it can illuminate the sheet and improve the imaging quality of the camera.

[0038] According to a preferred embodiment, a first light source 61 can be mounted on a mounting plate 51 and positioned directly below a first camera, and has a housing and a light-emitting device (not shown) installed within the housing. The housing of the first light source 61 also has a first transparent component 63 positioned within the field of view of the first camera, allowing the first camera to acquire a first image of the sheet through the first transparent component 63. This arrangement ensures that the first light source 61 can move with the first camera and provides a compact layout.

[0039] Furthermore, the second light source 62 is positioned directly above the second camera and has a housing and a light-emitting device installed within the housing. The housing of the second light source 62 has a second transparent component 64 positioned within the field of view of the second camera, so that the second light source 62 does not obstruct the field of view of the second camera.

[0040] According to the preferred embodiment shown in the accompanying drawings, such as Figure 1-2 As shown, the sheet bonding equipment may include a substrate 7, a sheet placement station 1, a target component placement station 2, a three-dimensional moving system 5, and a second light source 62 disposed on the upper surface of the substrate 7.

[0041] More preferably, such as Figure 2 As shown, in order to meet the focal length requirements of the second camera, the second camera can be positioned below the substrate 7 (e.g., fixed to the lower surface of the substrate 7 or fixed to other frame structures by any suitable means), and the substrate 7 includes a third transparent component 65 disposed within the field of view of the second camera, so that the second camera can acquire a second image of the sheet through the second transparent component 64 and the third transparent component 65.

[0042] The exemplary embodiments of this disclosure have been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
