[0002] In the process of assembling the circuit of the LCD panel, flexible circuit boards need to be inserted onto the circuit board. During the insertion process, the cover plate on the circuit board needs to be opened to assemble and insert the flexible circuit board into the circuit inside the cover plate. The operation of opening the cover plate is mostly done manually, which is inefficient and inconsistent. Often, some cover plates are not opened, so it is impossible to achieve the integration of automated equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a circuit board cover opening mechanism and system, which solves the problem that the cover of the circuit board to be assembled cannot be opened in time during the assembly process of flexible circuit boards, thus making it impossible to realize the matching of automated equipment.

[0004] In one embodiment of the present invention, a circuit board opening mechanism is provided, wherein a circuit cover is disposed on the surface of the circuit board. The circuit cover is rotatably connected to the circuit board via a pivot and forms a recess between the circuit cover and the circuit board to facilitate opening the circuit cover. The circuit board opening mechanism includes a clamping assembly and an opening assembly.

The clamping component includes a clamping end movable in the clamping direction, which is parallel to the width extension direction. The clamping plate is connected to the clamping end and can be located at the other end in the width extension direction, so that the width direction of the circuit board can be subjected to the clamping force of the clamping plate and the clamping plate. The recess can face the direction of the clamping plate.

[0008] The lid opening assembly is positioned along the width of the fixed platform and can be located at a position corresponding to the recess. The lid opening assembly includes: a first movable frame, a second movable frame, and a lid opening arm.

[0009] The first movable frame is capable of moving along a first moving direction. The first moving direction is perpendicular to the width extension direction.

[0010] The second movable frame is disposed on the first movable frame. The second movable frame includes a depth movable frame and a vertical movable frame. The depth movable frame is movable along a second moving direction and can be positioned at the open cover position. The second moving direction is parallel to the width extension direction. The open cover position is the location of the plane corresponding to the recess. The vertical movable frame is movable in a direction perpendicular to the fixed surface and can be positioned at the open cover height and the open cover movement height. The open cover height is the height position corresponding to the recess.

[0011] The cover opening arm is mounted on a vertically moving frame. The cover opening arm has a cover opening plate, the opening surface of which is parallel to the fixed surface, so that the cover opening plate can be inserted into the recess under the action of the first and second moving frames. When the vertically moving frame moves to the cover opening height, the circuit cover can be disengaged from its initial position around the pivot, so that the surface of the circuit cover is perpendicular to the surface of the circuit board.

[0012] In another embodiment of the circuit board opening mechanism, the circuit board has a line length extension direction and a line width extension direction. The circuit cover is disposed at one end in the line width extension direction. The recess faces outwards from the circuit board.

[0013] The mounting platform includes a fixed length extension direction. This fixed length extension direction can be parallel to the line length extension direction. A mounting protrusion is formed along the fixed length extension direction, and intersects with the edge of the mounting surface.

[0014] Multiple suction holes are sequentially formed on the fixed surface along its extension direction. They are connected to a negative pressure air supply system so that the multiple suction holes can create a negative pressure suction force on the bottom surface of the circuit board.

[0015] In another embodiment of the circuit board opening mechanism, the clamping mechanism includes a clamping support platform and a clamping motor. The clamping support platform includes a clamping surface. The clamping motor is disposed on the clamping support platform and has a movable end formed by transmission via a sliding screw pair transmission mechanism, the end of which is a clamping end. The axial direction of the movable end is parallel to the width extension direction.

[0016] The clamping plate also includes a clamping plate base. The clamping plate base is slidably mounted on the clamping support table via a slide rail. The moving end is connected to the clamping plate base via a coupling. The clamping plate base forms a sliding surface parallel to the clamping table surface. A clamping groove is formed on the sliding surface. The extending direction of the clamping groove is perpendicular to the width extension direction.

[0017] In another embodiment of the circuit board opening mechanism, the invention further includes: a clamping pressure plate having its surface disposed within a clamping groove, and capable of being assembled and fixed at multiple positions within the clamping groove. The surface of the clamping pressure plate is perpendicular to the clamping table surface and has a surface extension direction. The surface extension direction is parallel to the extension direction of the clamping groove. At one end of the clamping pressure plate that is assembled with the circuit board, a clamping protrusion is formed along the surface extension direction, facing the edge of the circuit board.

[0018] The height of the clamping protrusion corresponds to the distance between the circuit cover and the edge of the circuit board. The outward-facing end of the clamping protrusion includes the inner edge facing the pressure plate seat. A straight chamfer or a curved chamfer is formed on the inner edge.

[0019] In another embodiment of the circuit board opening mechanism, the first moving frame includes: a first support frame, a main frame, and a first moving motor.

[0020] The first support frame includes a first support surface, which has a first support length direction parallel to the fixed length extension direction. A first slide rail is provided along the first support length direction. A main frame is slidably disposed on the first slide rail and includes a main support surface. The main support surface is perpendicular to the first support surface.

[0021] The first moving motor is mounted on the first support surface. The rotation output shaft of the first moving motor is connected to the main frame through a sliding screw pair transmission mechanism, so that the main frame moves along the extension direction of the first slide rail under the drive of the first moving motor to a position that corresponds to the recess.

[0022] In another embodiment of the circuit board opening mechanism, the depth movement frame includes a depth slide rail and a depth movement motor. The depth slide rail is disposed on the main support surface, and the extension direction of the depth slide rail is perpendicular to the length direction of the first support.

[0023] A depth-moving motor is mounted on the main support surface. The rotation output shaft of the depth-moving motor is connected to the vertical moving frame via a sliding helical pair transmission mechanism, so that the vertical moving frame can move along the extension direction of the depth slide rail and be positioned in the open position.

[0024] In another embodiment of the circuit board opening mechanism, the vertical moving frame includes: a vertical support base, a vertical belt reduction module, a vertical motor, a vertical slide rail, and a vertical slider.

[0025] The vertical support base connects to the moving output end of the sliding helical pair transmission mechanism of the depth-moving frame. The vertical support base includes a first vertical surface and a second vertical surface. The first and second vertical surfaces are parallel to the overall support surface.

[0026] The vertical belt reduction module includes a vertical driving pulley and a vertical driven pulley. The vertical driving pulley and the vertical driven pulley are connected by a belt drive.

[0027] A vertical motor is positioned on the first vertical plane. The output shaft of the vertical motor is parallel to the first vertical plane. The output shaft of the vertical motor is connected to a vertical drive pulley.

[0028] A vertical slide rail is positioned on the second vertical plane. A vertical slider is slidably mounted on the vertical slide rail and moves along the vertical slide rail via the moving output end of the vertical sliding screw pair transmission mechanism. The rotation input shaft of the vertical sliding screw pair transmission mechanism is parallel to the output shaft of the vertical motor and connected to the vertical driven pulley, so that the output torque of the vertical motor can be transmitted to the rotation input shaft of the vertical sliding screw pair transmission mechanism.

[0029] In another embodiment of the circuit board opening mechanism, the opening arm includes a horizontal arm and a vertical arm. The horizontal arm is connected to the vertical slider and is perpendicular to a second vertical plane. The vertical arm is connected to the end of the horizontal arm away from the vertical slider. An opening tab is provided at the end of the vertical arm away from the horizontal arm.

[0030] The vertical arm, at its end away from the horizontal arm, includes an opening abutment surface that is perpendicular to the fixed surface. The opening abutment surface intersects with the opening flaps. The outer edges of the opening flaps include rounded or 45° chamfered edges.

[0031] In another embodiment of the circuit board opening mechanism, the invention further includes a camera device and a lighting device. The camera device is connected to the second movable frame via a support frame. The camera end of the camera device is positioned at a position corresponding to the opening arm. The opening arm forms an outwardly bent portion along a second moving direction. The camera device is disposed within the bent portion.

[0044] To provide a clearer understanding of the technical features, objectives, and effects of the invention, specific embodiments of the invention are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0045] In this document, "illustrative" means "serving as an example, illustration, or description," and any illustrations or embodiments described herein as "illustrative" should not be construed as a more preferred or advantageous technical solution. For the sake of brevity, each figure only schematically shows the parts relevant to this exemplary embodiment, and they do not represent the actual structure or true proportions of the product.

[0046] Figure 1 This is a schematic diagram illustrating the structure of the circuit board opening mechanism in one embodiment of the present invention. (Refer to...) Figures 1-3 In one embodiment of the present invention, a circuit board opening mechanism is provided, wherein a circuit cover 91 is provided on the surface of the circuit board. The circuit cover 91 is rotatably connected to the circuit board via a pivot and forms a recess 92 between the circuit cover 91 and the circuit board to facilitate opening the circuit cover 91. The circuit board opening mechanism includes a clamping assembly 100 and an opening assembly 200.

[0047] Reference Figures 1-3The clamping assembly 100 includes a fixing platform 10 and a clamping mechanism 20. The fixing platform 10 includes a fixing surface capable of supporting the bottom surface of the circuit board 90. A fixing protrusion 11 is provided at one end of the fixing surface in the width extension direction K.

[0048] Reference Figures 1-3 The clamping mechanism 20 includes a clamping plate 21 and a clamping component 22. The clamping component 22 includes a clamping end movable in the clamping direction, which is parallel to the width extension direction K. The clamping plate 21 is connected to the clamping end and can be located at the other end in the width extension direction K, so that the width direction of the circuit board 90 can be subjected to the clamping force of the clamping plate 21. The recess 92 can face the clamping plate 21.

[0049] Reference Figure 1 , Figure 4 The lid opening assembly 200 is disposed in the width direction of the fixed platform 10 and can be located at the position corresponding to the recess 92. The lid opening assembly 200 includes: a first movable frame 30, a second movable frame 40, and a lid opening arm 50. The first movable frame 30 is movable along a first moving direction A1. The first moving direction A1 is perpendicular to the width extension direction K.

[0050] Reference Figure 1 , Figure 4 A second movable frame 40 is disposed on top of the first movable frame 30. The second movable frame 40 includes a depth movable frame 41 and a vertical movable frame 42. The depth movable frame 41 is movable along a second moving direction A2 and can be located at the open position. The second moving direction A2 is parallel to the width extension direction K. The open position is the location of the plane corresponding to the recess 92. The vertical movable frame 42 is movable in a direction perpendicular to the fixed surface and can be located at the open height and the open movement height. The open height is the height position corresponding to the recess 92.

[0051] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 The opening arm 50 is mounted on the vertical moving frame 42. The opening arm 50 has an opening tab 51, the opening surface of which is parallel to the fixed surface, so that the opening tab 51 can be inserted into the recess 92 (i.e., ...) under the action of the first moving frame 30 and the second moving frame 40. Figure 5 (as shown in the figure) When the vertical moving frame 42 moves to the opening moving height, the circuit cover 91 can be disengaged from the initial position around the pivot, so that the surface of the circuit cover 91 is perpendicular to the surface of the circuit board 90.

[0052] Therefore, the working process of the circuit board opening mechanism in this invention is as follows:

[0053] The first step is to assemble the circuit board 90 onto the fixed platform 10. This assembly process can be automated using other assembly equipment. The clamping mechanism 20 is activated, causing the clamping plate 21 to move in the width extension direction K, so that the circuit board 90 is subjected to the clamping force of the clamping plate 21 in the width direction. This completes the clamping and fixing of the circuit board.

[0054] The second step involves activating the first movable bracket 30 in the cover opening assembly 200 to align it with the mounting position of the circuit board, and then activating the second movable bracket 40 until... Figure 5 The position of the cover-opening arm 50 is such that the opening plate 51 of the cover-opening arm 50 corresponds to the recessed portion 92 of the circuit cover 91. When the cover-opening arm 50 moves upward with the second moving frame 40, the circuit cover 91 rotates smoothly around the pivot to a vertical position. Furthermore, the closing operation can also be achieved through the reverse control of the above-mentioned device.

[0055] Therefore, the circuit board opening mechanism of this invention solves the technical problems of low positioning accuracy, unstable clamping, uncontrollable opening force, poor operational consistency, and difficulty in integration into automated production lines that exist in traditional manual opening methods. Thus, this invention, through its three-dimensionally positionable opening arm, can accurately position itself in the three-dimensional space formed by the first moving direction A1, the second moving direction A2, and the vertical direction, and achieves non-destructive insertion through the geometric matching of the opening piece 51 and the recessed portion 92.

[0056] The front end of the opening plate 51 is provided with a guide chamfer to avoid interference with the edge of the recessed part 92; the opening arm 50 and the vertical moving frame 42 are connected by a linear guide pair to ensure that the opening surface is always parallel to the fixed surface during the opening action, thereby ensuring the uniqueness and repeatability of the movement trajectory of the circuit cover 91 during the rotation process around the axis.

[0057] Therefore, it improves the positioning accuracy and repeatability of the circuit board opening mechanism, and significantly reduces the circuit cover damage rate and opening failure rate caused by manual operation, especially in mass production; thus, it can be matched with automated assembly equipment, improving the automation level of the overall circuit board processing and the efficiency of production line integration.

[0058] like Figure 1 , Figure 8 As shown, in another embodiment of the circuit board opening mechanism, the circuit board has a line length extension direction and a line width extension direction K. A circuit cover 91 is provided at one end in the line width extension direction K. A recess 92 faces the outside of the circuit board.

[0059] like Figure 1 , Figure 8As shown, the mounting platform 10 includes a fixed length extension direction. This fixed length extension direction can be parallel to the line length extension direction. A fixing protrusion 11 is formed along the fixed length extension direction, and intersects with the edge of the fixing surface. A plurality of suction holes 12 are sequentially formed on the fixing surface along its extension direction. These holes are connected to a negative pressure air supply system, so that the plurality of suction holes 12 can create a negative pressure suction force on the bottom surface of the circuit board. This enhances the positioning suction force on the circuit board 90, making the circuit board more securely fixed.

[0060] like Figure 1 , Figure 2 As shown, in another embodiment of the circuit board opening mechanism, the clamping mechanism 20 includes a clamping support platform 23 and a clamping motor 24. The clamping support platform 23 includes a clamping surface. The clamping motor 24 is disposed on the clamping support platform 23 and has a movable end formed by transmission via a sliding screw pair transmission mechanism, the end of which is a clamping end. The axial direction of the movable end is parallel to the width extension direction K. The aforementioned sliding screw pair transmission mechanism is a lead screw and nut transmission structure. The lead screw is 25 as shown in the figure, and the nut is 26.

[0061] The clamping plate 21 also includes a clamping plate base 27. The clamping plate base 27 is slidably mounted on the clamping support table 23 via a slide rail. The moving end is connected to the clamping plate base 27 via a coupling. The clamping plate base 27 forms a sliding surface parallel to the clamping table surface. A clamping groove 28 is formed on the sliding surface. The extending direction of the clamping groove 28 is perpendicular to the width extending direction K.

[0062] In another embodiment of the circuit board opening mechanism, the invention further includes: a clamping plate 21 with its surface disposed within a clamping groove 28, and capable of being assembled and fixed at multiple positions within the clamping groove 28. The surface of the clamping plate 21 is perpendicular to the clamping table surface and has a surface extension direction. The surface extension direction of the clamping plate 21 is parallel to the extension direction of the clamping groove 28. At one end of the clamping plate 21 that is assembled with the circuit board, a clamping protrusion 29 is formed along the surface extension direction of the clamping plate 21, which is oriented towards the edge of the circuit board.

[0063] The protrusion height of the clamping protrusion 29 corresponds to the distance between the circuit cover 91 and the edge of the circuit board. The outward-facing end of the clamping protrusion 29 includes an inner edge facing the pressure plate seat 27. A straight chamfer or a curved chamfer is formed on the inner edge, making it easier to position the edge of the circuit board.

[0064] like Figure 4 As shown, in another embodiment of the circuit board opening mechanism, the first moving frame 30 includes: a first support frame 31, a main frame 32, and a first moving motor 33.

[0065] like Figure 4As shown, the first support frame 31 includes a first support surface, which has a first support length direction parallel to the fixed length extension direction. A first slide rail is provided along the first support length direction. The main frame 32 is slidably disposed on the first slide rail and includes a main support surface. The main support surface is perpendicular to the first support surface.

[0066] like Figure 4 As shown, the first moving motor 33 is mounted on the first support surface. The rotation output shaft of the first moving motor 33 is connected to the main frame 32 via a sliding screw pair transmission mechanism, so that the main frame 32, driven by the first moving motor 33, moves along the extension direction of the first slide rail to a position corresponding to the recess 92. The aforementioned sliding screw pair transmission mechanism is a lead screw and nut structure, consistent with the similar structure mentioned above, and will not be described again here.

[0067] like Figure 4 As shown, in another embodiment of the circuit board opening mechanism, the depth moving frame 41 includes a depth slide rail 43 and a depth moving motor 44. The depth slide rail 43 is disposed on the main support surface, and the extending direction of the depth slide rail 43 is perpendicular to the length direction of the first support.

[0068] like Figure 4 As shown, a depth-moving motor 44 is mounted on the main support surface. The rotation output shaft of the depth-moving motor is connected to the vertical moving frame 42 via a sliding helical pair transmission mechanism, so that the vertical moving frame 42 can move along the extension direction of the depth slide rail 43 and can be positioned in the open position.

[0069] In another embodiment of the circuit board opening mechanism, the vertical moving frame 42 includes: a vertical support base 71, a vertical belt reduction module 72, a vertical motor 73, a vertical slide rail 74, and a vertical slider 75.

[0070] The vertical support base 71 connects to the moving output end of the sliding helical transmission mechanism of the depth moving frame 41. The vertical support base 71 includes a first vertical surface and a second vertical surface. The first and second vertical surfaces are parallel to the overall support surface.

[0071] The vertical belt reduction module 72 includes a vertical driving pulley and a vertical driven pulley. The vertical driving pulley and the vertical driven pulley are connected by a belt drive.

[0072] A vertical motor 73 is mounted on a first vertical plane. The output shaft of the vertical motor 73 is parallel to the first vertical plane. The output shaft of the vertical motor 73 is connected to a vertical drive pulley.

[0073] A vertical slide rail 74 is disposed on the second vertical plane. A vertical slider 75 is slidably disposed on the vertical slide rail 74 and is driven to move on the vertical slide rail 74 by the moving output end of the vertical sliding screw pair transmission mechanism. The rotation input shaft of the vertical sliding screw pair transmission mechanism is parallel to the output shaft of the vertical motor 73 and connected to the vertical driven pulley, so that the output torque of the vertical motor 73 can be transmitted to the rotation input shaft of the vertical sliding screw pair transmission mechanism. This makes the overall structure more compact.

[0074] In another embodiment of the circuit board opening mechanism, the opening arm 50 includes a horizontal arm 52 and a vertical arm 53. The horizontal arm 52 is connected to the vertical slider 75 and is perpendicular to the second vertical plane. The vertical arm 53 is connected to the end of the horizontal arm 52 away from the vertical slider 75. An opening piece 51 is provided at the end of the vertical arm 53 away from the horizontal arm 52.

[0075] The vertical arm 53, at its end away from the horizontal arm 52, includes an opening abutment surface 54 that is perpendicular to the fixed surface. The opening abutment surface 54 intersects with the opening tabs 51. The outer edges of the opening tabs 51 include arcs or 45° chamfers. This allows the opening tabs to make a flexible cut when contacting the circuit board cover, avoiding hard scratches; the force distribution at the intersection is optimized by finite element method to ensure that the abutment surface and the opening tabs work together to ensure that the cover separates smoothly along a preset trajectory.

[0076] In another embodiment of the circuit board opening mechanism, the invention further includes a camera device 81 and a lighting device. The camera device 81 is connected to the second movable frame 40 via a support frame. The camera end of the camera device 81 is positioned corresponding to the opening arm 50. The opening arm 50 forms an outwardly bent portion along the second moving direction A2. The camera device 81 is disposed within the bent portion. The camera device 81 captures images after opening and before opening. The lighting device is configured to illuminate when the camera device 81 takes a picture.

[0077] In another embodiment of the circuit board opening mechanism, the invention further includes a main controller with multiple input and output terminals. The output terminals are connected to the drive terminals of the suction / negative pressure air supply system, the clamping motor 24, the control motor of the first moving frame 30, the control motor of the second moving frame 40, the camera device 81, and the lighting device, respectively. The main controller can be an industrial-grade PLC controller, integrating an EtherCAT bus communication module, supporting real-time image recognition algorithm embedding and air pressure closed-loop feedback regulation. Its input terminals are connected to a suction / negative pressure sensor, a clamping force sensor, and multiple position sensors, thereby providing auxiliary positioning.

[0078] After the driving suction negative pressure air supply system and clamping motor 24 are activated, the control motors of the first moving frame 30 and the second moving frame 40 are activated according to the set movement amount, and the camera device 81 operates to enable the lid opening arm 50 to complete the lid opening operation and acquire images before and after the lid is opened. The images after and before the lid is opened are then compared in real time by the algorithm embedded in the main controller to automatically identify the opening and closing status of the lid. Without the need for external data, real-time status judgment and abnormal warnings can be performed through the images.

[0079] It should be understood that although this specification describes various embodiments, not every embodiment contains only independent technical solutions. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
