Description

Technical Field

[0001] The utility model relates to the technical field of pressing plates, in particular to a flexible pressing plate mechanism. Background Art

[0002] In the field of glue dispensing, when performing glue dispensing operations on polygonal panels that are large in size and prone to warping at the edges, a pressure plate mechanism is required to press the edges of the polygonal panels to ensure the flatness of the polygonal panels during the glue dispensing operation. Existing pressure plate mechanisms mainly use a pressure plate to directly press the edges of the polygonal panels to flatten the polygonal panels as a whole. However, for polygonal panels with a large amount of warping (about 10mm), when using the existing pressure plate mechanism to press the warped edges, the contact position between the pressure plate and the edge of the polygonal panel will change during the pressing process. The friction generated by the relative movement between the two will damage the polygonal panel, especially for some relatively brittle polygonal panels, which are very easy to crush or crack.

DETAILED DESCRIPTION

[0033] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0035] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 9As shown, the flexible pressure plate mechanism of the present invention includes: a longitudinal drive component 1, a transverse drive component 2 and a pressure plate 3. The transverse drive component 2 is installed on the longitudinal drive component 1, and the longitudinal drive component 1 can drive the transverse drive component 2 to move up and down; the pressure plate 3 is connected to the transverse drive component 2, and the pressure plate 3 can move in the horizontal direction under the drive of the transverse drive component 2; wherein, a universal pressure head 31 is provided on the pressure plate 3, and when the universal pressure head 31 presses down the warped edge of the polygonal panel 100, the universal pressure head 31 can adaptively adjust the contact position with the warped edge.

[0037] In other words, this embodiment does not directly contact the edge of the polygonal panel 100 with the pressing plate 3, but instead provides a universal pressing head 31 to contact the edge of the polygonal panel 100. During the pressing process, as the warped edge is gradually flattened, the universal pressing head 31 can adaptively adjust its position relative to the polygonal panel 100 under the action of friction, preventing the polygonal panel 100 from being damaged by friction. Moreover, compared to the pressing plate 3 directly pressing the polygonal panel 100, the pressing plate 3 and the polygonal panel 100 are in surface contact, while the universal pressing head 31 and the polygonal panel 100 are in point contact, resulting in a smaller contact area with the polygonal panel 100. The surface of the polygonal panel 100 is equipped with a precise chip or circuit structure, and small-area contact is less likely to damage the effective area on the polygonal panel 100. The longitudinal drive assembly 1 and the transverse drive assembly 2 can drive the pressing plate 3 to move to the specified position.

[0038] For example, the universal pressure head 31 is made of polyetheretherketone (PEK) material, which has the advantages of high temperature resistance, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardancy, peeling resistance, radiation resistance, and stable insulation. In addition, the friction coefficient of the polyetheretherketone material is small, which helps to reduce the friction and wear of the polygonal panel 100; the self-lubricating property of the polyetheretherketone material can secrete lubricant by itself during operation, which helps to further reduce wear.

[0039] For example, when the flexible pressing plate mechanism presses down the edge of the polygonal panel 100 , the polygonal panel 100 is placed on the carrying platform 200 .

[0040] For example, the universal pressure head 31 includes: a connecting portion 311 and a ball 312, and most of the volume of the ball 312 is located in the receiving groove of the connecting portion 311. A mounting hole 32 is provided on the pressure plate 3, and the upper end of the connecting portion 311 is installed in the mounting hole 32. It should be noted that the ball 312 can rotate freely and will not fall off from the receiving groove. The connecting portion 311 is arranged vertically to the pressure plate 3. When pressing down, the ball 312 contacts the edge of the polygonal panel 100. As the warping amount decreases, the ball 312 can adaptively adjust the contact position with the warped edge under the action of friction. It can be understood that the warped edge is roughly arc-shaped, and the ball 312 is not stuck in the receiving groove, but can rotate. During the downward pressure of the universal pressing head 31, the ball 312 contacts the warped edge. Assuming that the initial contact position between the ball 312 and the warped edge is point A, as the warped edge gradually flattens, the contact position changes from point A to point B. During the downward pressure process, the ball 312 generates a certain amount of friction due to the change in contact position, which may scratch the panel. However, the ball 312 of this embodiment is freely rotatable. When the contact position changes, this friction can be offset by the rotation of the ball 312, thereby preventing the panel from being scratched. In addition, the ball 312 of this embodiment is in point contact with the warped edge, with a smaller contact area, which can further reduce the risk of damage to the polygonal panel 100 during the downward pressure process.

[0041] For example, the pressing plate 3 may be provided with a plurality of universal pressing heads 31, and the plurality of universal pressing heads 31 may be arranged on the same straight line. For a larger polygonal panel 100, the number of universal pressing heads 31 may be increased, and for a smaller polygonal panel 100, the number of universal pressing heads 31 may be decreased.

[0042] Specifically, the flexible pressure plate mechanism also includes a first mounting block 5, a second mounting block 6, and a first connecting plate 7. The first mounting block 5 is connected to the transverse drive assembly 2, the second mounting block 6 is connected to the first mounting block 5, the first connecting plate 7 is slidably connected to the first mounting block 5, and the pressure plate 3 is connected to the first connecting plate 7. The first mounting block 5 is provided with a slide rail 51 and a slider 52. The slider 52 is slidably connected to the slide rail 51 and is connected to the first connecting plate 7. The first connecting plate 7 and the second mounting block 6 do not contact each other. The second mounting block 6 is arranged horizontally, while the first mounting block 5 and the first connecting plate 7 are arranged vertically. In other words, the second mounting block 6 moves with the first mounting block 5. In addition to moving with the first mounting block 5, the first connecting plate 7 can also move vertically relative to the first mounting block 5. The flexible pressure plate mechanism also includes a pressure detection assembly 4, which is mounted on the second mounting block 6 and is used to detect the force applied by the pressure plate 3 against the edge of the polygonal panel 100. The pressure detection assembly 4 includes: a pressure sensor 41 and a pressure calibration platform 42. One end of the pressure sensor 41 is connected to the first connecting plate 7, and the other end extends into the second mounting block 6 and is connected to the pressure calibration platform 42. The pressure calibration platform 42 is located on the upper surface of the second mounting block 6.

[0043] When the pressure plate 3 drives the universal pressure head 31 to press the warped edge, the warped edge generates an upward reaction force on the universal pressure head 31. This reaction force causes the pressure plate 3 and the first connecting plate 7 to move upward, causing the first connecting plate 7 and the pressure plate 3 to move upward a small distance. The upward movement of the first connecting plate 7 squeezes the pressure sensor 41, thereby detecting the pressure value of the universal pressure head 31 on the warped edge. The pressure calibration platform 42 is used to calibrate and adjust the pressure sensor 41 to ensure the accuracy of the detected pressure value.

[0044] For example, the first mounting block 5 is provided with a first stopper 8. The first stopper 8 is used to prevent the first connecting plate 7 from falling. The first stopper 8 is located at the lower end of the first mounting block 5. As previously described, when the universal pressing head 31 presses down on the warped edge of the polygonal panel 100, the reaction force causes the first connecting plate 7 to move upward a small distance. Then, when the pressing process ends and the universal pressing head 31 leaves the polygonal panel 100, the first connecting plate 7 moves downward under the action of gravity. At this time, the first stopper 8 can limit the downward movement of the first connecting plate 7, preventing it from falling.

[0045] The flexible pressure plate mechanism also includes a base 9, on which a longitudinal drive assembly 1 is mounted. A photoelectric sensor 10 is also provided on the base 9 for detecting whether the pressure plate 3 has reached a specified height. Specifically, the longitudinal drive assembly 1 includes a longitudinal drive member 101, a transmission module 102, a screw module 103, and a longitudinal drive plate 104. The screw module 103 is connected to the longitudinal drive member 101 via the transmission module 102, which is in turn connected to the longitudinal drive plate 104, which is in turn connected to the transverse drive assembly 2. A baffle 1041 is connected to the longitudinal drive plate 104. There are two photoelectric sensors 10 (referred to as photoelectric sensors a and b, with photoelectric sensor a located directly above photoelectric sensor b). When the longitudinal drive plate 104 moves up and down, it drives the baffles 1041 up and down with it. When the baffles 1041 engage with the photoelectric sensors 10, a sensing signal is triggered. Photoelectric sensor a corresponds to the position of the longitudinal drive plate 104 when it reaches the specified height, while photoelectric sensor b corresponds to the initial position of the longitudinal drive plate 104. For example, the transmission module 102 includes a synchronous belt 1021 and two synchronous pulleys 1022. One synchronous pulley 1022 is connected to the output shaft of the longitudinal drive member 101, and the other synchronous pulley 1022 is connected to the lead screw of the lead screw module 103. The synchronous belt 1021 is mounted on the two synchronous pulleys 1022, and the nut of the lead screw module 103 is connected to the longitudinal drive plate 104. When the longitudinal drive member 101 is started, the lead screw is rotated by the synchronous pulley 1022 and the synchronous belt 1021. The rotation of the lead screw causes the nut to move up and down, thereby driving the longitudinal drive plate 104 to move up and down.

[0046] Specifically, the transverse drive assembly 2 includes a transverse mounting plate 201, a transverse drive member 202, a transverse guide rail 203, and a transverse drive plate 204. The transverse mounting plate 201 is connected to the longitudinal drive assembly 1, and the transverse drive plate 204 is connected to the transverse mounting plate 201 via the transverse guide rail 203. The transverse drive member 202 is mounted on the transverse mounting plate 201, and the transverse drive plate 204 is connected to the transverse drive member 202. Specifically, the transverse mounting plate 201 is connected to the longitudinal drive plate 104, and the transverse drive plate 204 is connected to the first mounting block 5. When the transverse drive member 202 is activated, it can drive the transverse drive plate 204 to move horizontally. The transverse guide rail 203 helps to improve the stability of the transverse drive plate 204 during movement. For example, the transverse drive plate 204 is also provided with a second limit block 205, and the transverse mounting plate 201 is provided with a third limit block 207 to limit the horizontal travel of the transverse drive plate 204. The third limit block 207 is located near the output end of the transverse driving member 202. A buffer 206 is provided on the second limit block 205. When the transverse driving member 202 is started, it can drive the transverse driving plate 204 to extend or retract horizontally. When the transverse driving plate 204 extends, the second limit block 205 also moves horizontally. When the end of the buffer 206 abuts against the third limit block 207, the transverse driving plate 204 stops extending.

[0047] In one embodiment, there is one longitudinal drive assembly 1, one transverse drive assembly 2, and one pressing plate 3, which is suitable for small-sized polygonal panels 100. In one embodiment, there is one longitudinal drive assembly 1, one transverse drive assembly 2, and multiple pressing plates 3, which is suitable for medium-sized polygonal panels 100. In one embodiment, there is one longitudinal drive assembly 1, multiple transverse drive assemblies 2, and multiple pressing plates 3 on each transverse drive assembly 2, which is suitable for large-sized polygonal panels 100.

[0048] Working process:

[0049] In the initial state, the pressing plate 3 is in the initial position. When the polygonal panel 100 is placed on the working platform (the flexible pressing plate mechanism is located on the side of the working platform), the longitudinal drive component 1 drives the transverse drive component 2 and the pressing plate 3 to move upward to the specified height. Then, the transverse drive component 2 drives the pressing plate 3 to extend horizontally, so that the universal pressure head 31 is located directly above the warped edge of the polygonal panel 100. Then, the longitudinal drive component 1 drives the transverse drive component 2 and the pressing plate 3 to move downward together. During this downward movement, the universal pressure head 31 gradually flattens the warped edge. During the flattening process, the contact position of the universal pressure head 31 with the warped edge can be adaptively adjusted.

[0050] In summary, the flexible pressure plate mechanism of the present invention utilizes a universal pressure head 31 in contact with the edge of the polygonal panel 100. During downward pressure, as the warped edge is gradually flattened, the universal pressure head 31 rotates relative to the polygonal panel 100 under the action of friction, preventing damage to the polygonal panel 100 due to friction. Furthermore, the universal pressure head 31 makes point contact with the polygonal panel 100, resulting in a smaller contact area with the panel 100. This small contact area is less likely to damage the active area of ​​the polygonal panel 100.
