Description

Technical Field

[0001] This invention relates to an automatic pressure application device, and more particularly to an automatic pressure application device for bonding fragile flat surfaces. Background Technology

[0002] During product manufacturing, it is necessary to bond the base to a fragile surface (such as glass). Therefore, a method is needed to apply stable pressure to the fragile surface and the base without damaging the fragile surface.

[0003] The commonly used pressure application method in existing technologies is manual, slow pressing. During this process, because the pressure and time are manually controlled, when the adhesive is viscous, a large and sustained pressure is required. This leads to uneven stress on fragile surfaces, potentially resulting in incomplete flattening of the surface, uneven adhesive distribution underneath, and internal stress within the adhesive during curing. Furthermore, operators are prone to fatigue, and the pressure application efficiency is low. Therefore, this traditional manual pressure application method cannot effectively control the pressure application effect and quality, and its efficiency is low. Summary of the Invention

[0004] This invention provides an automatic pressure application device for bonding fragile flat surfaces, which can solve the technical problems of existing manual pressure application methods that cannot effectively control the pressure effect and quality, and have low pressure application efficiency.

[0010] The second slide rail is fixed to the upper surface of the chassis, and the movable base is slidably installed on the second slide rail for placing and fixing the base to be bonded, and ensuring that when the base to be bonded is placed on it, the bonding plane is parallel and can be directly opposite the upper pressure plate and pressure sensor.

[0014] Preferably,

[0027] Specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details are set forth for purposes of explanation and not limitation, in order to aid in a thorough understanding of the present invention.

[0028] It should be noted that, in order to avoid obscuring the invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0029] like Figure 1 As shown in the figure, an automatic pressure application device for fragile flat bonding is provided according to a specific embodiment of the present invention. The automatic pressure application device includes a housing 1, a second slide rail 3, a movable base 4, an upper pressure plate 5, a pneumatic / electric linear motion mechanism 6, a pressure sensor 8, a start button 9, an emergency stop button 10, a support frame 11, and a first slide rail 12.

[0030] The chassis 1 includes, but is not limited to, a microcontroller (MCU) and a central processing unit (CPU) control circuit, used to control the timing and position of the movable base 4, control the movement length and timing of the pneumatic / electric linear motion mechanism 6, collect the applied pressure measured by the pressure sensor 8, and has a timing function. Its circuit structure and control program are widely used in the industry, therefore, they will not be described in detail.

[0031] The support frame 11 is U-shaped and installed on the upper surface of the housing 1. It is used to install the first slide rails 12 for the vertical movement of the upper pressure plate 5. There are four first slide rails 12, each vertically fixed in pairs on both sides between the upper plate of the support frame and the housing 1. The upper surface of the support frame 11 is provided with through holes for the extension connecting rod of the pneumatic / electric linear motion mechanism 6 to pass through. The end of the extension connecting rod is fixedly connected to the upper pressure plate 5.

[0032] The pressure sensor 8 is fixedly installed on the lower surface of the upper pressure plate 5 and is used to measure the downward pressure during the pressure application process. In order to ensure that the downward pressure is vertical, the upper pressure plate 5 and the pressure sensor 8 must be securely installed and kept parallel.

[0033] The upper pressure plate 5 is slidably mounted on the first slide rail 12 and is used to transmit the downward pressure of the pneumatic / electric linear motion mechanism 6 to the pressure sensor 8. During the downward pressing process, the guide rail restricts its position to ensure that the downward pressure is perpendicular to the pressure sensor 8.

[0034] The second slide rail 3 consists of two rails, which are arranged in parallel on the upper surface of the chassis (including the control circuit) 1, for the movement and positioning of the movable base 4.

[0035] The movable base 4 is slidably installed on the two rails of the second slide rail 3 for placing and fixing the base to be bonded. Its shape should conform to the appearance characteristics of the base and ensure that when the base to be bonded is placed on it, the bonding plane is parallel and can be directly opposite the upper pressure plate 5 and the pressure sensor 8.

[0036] The pneumatic / electric linear motion mechanism 6 includes, but is not limited to, cylinders, linear motors, lead screw motors, belt linear modules, and other automatic linear motion mechanisms.

[0037] The start button 9 and the emergency stop button 10 are used to control the start of the device's downward pressure and emergency stop.

[0038] In one specific embodiment, the upper pressure plate 5, on which the pressure sensor 8 is installed, is preferably connected to the support frame 11 via an adapter plate 13 to ensure reliable installation. The upper pressure plate 5 and the adapter plate 13 are fixedly connected by bolts, and the adapter plate 13 is slidably connected to the first slide rail 12 via a slider fixedly mounted thereon. The end of the extension connecting rod of the pneumatic / electric linear motion mechanism 6 is fixedly connected to the adapter plate 13.

[0039] In one specific embodiment, when a pneumatic linear motion mechanism is selected, an air filter 7 is preferably used.

[0040] In one specific embodiment, in order to ensure that the pressure sensor 8 and the movable base 4 are aligned, a positioning device is provided on the second slide rail 3 to ensure that the movable base 4 can accurately reach directly below the pressure sensor 8 under the control of the chassis 1.

[0041] In one specific embodiment, the chassis 1, movable base 4, upper pressure plate 5 and support frame 11 are all made of aluminum alloy and have undergone special surface treatment to ensure that the materials have strong mechanical strength and corrosion resistance; the pressure sensor 8 is covered with soft rubber material to protect the fragile surface.

[0042] In one specific embodiment, the handles 2 are installed on both sides of the chassis 1 for carrying the pressure application device.

[0043] The specific operation process of this invention is as follows: The base to be bonded is fixed to the movable base. The start button is pressed, and the movable base, under the control of the chassis, precisely reaches directly below the pressure sensor. The pneumatic / electric linear motion mechanism moves downwards, generating downward pressure on the upper pressure plate. The chassis collects the applied pressure measured by the pressure sensor and adjusts the movement length of the pneumatic / electric linear motion mechanism according to the pressure measured by the pressure sensor. After reaching the preset pressure value, the pneumatic / electric linear motion mechanism stops pressing down and maintains the pressure for a preset holding time. During this process, the pneumatic / electric linear motion mechanism and the pressure sensor constitute a negative feedback control system, ensuring that the pressure between the fragile surface and the base to be bonded is always at the set value. When the pressure reaches the preset value, timing begins. When the timing ends, the pneumatic / electric linear motion mechanism and the movable base return to the zero position.

[0044] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, whole, step, or component, but does not exclude the presence or addition of one or more other features, wholes, steps, components, or combinations thereof.

[0045] Many features and advantages of these embodiments are apparent from this detailed description, and therefore the appended claims are intended to cover all such features and advantages of these embodiments that fall within their true spirit and scope. Furthermore, since many modifications and alterations will readily occur to those skilled in the art, the embodiments of the invention are not intended to be limited to the precise structures and operations illustrated and described, but rather to encompass all suitable modifications and equivalents falling within their scope.
