Description

Technical Field

[0002] A rigid-flex board is a composite material composed of a flexible circuit board and a rigid circuit board through processes such as pressing. It has the characteristics of hard-soft combination, good flexibility, and wear resistance. It is widely used in electronic equipment, automobiles, furniture and other fields. The production process of a rigid-flex board mainly includes raw material preparation, hard-soft combination processing, hot pressing molding, repair processing, etc.

[0003] At present, the hard-soft bonding process is a key step in the production of hard-soft boards. By combining soft materials with hard materials, a hard-soft bonding layer is formed, including surface treatment, adhesive selection, bonding and curing. Generally, glue is applied to the surface of the hard board, and then the soft board is placed on the surface of the hard board for pressing. However, during the pressing process, excess glue may flow out from the gap and remain on the hard board and the soft board, which will also cause waste of glue.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] For specific embodiment 1, please refer to Figure 1-19 The present invention is a coating device for processing a soft-hard combined board, comprising a glue storage box 1; a placing plate 2 is fixed to the bottom surface of the glue storage box 1; an L-shaped mounting frame 3 is fixed to the surface of the glue storage box 1; a guide track is provided on the top surface of the L-shaped mounting frame 3; the guide track comprises a closed inner track 4 and a semi-closed outer track 5; both ends of the semi-closed outer track 5 are connected with the closed inner track 4 by a transition curve; the closed inner track 4 and the semi-closed outer track 5 form a closed guide track; a rotating block 6 is rotatably provided on the part of the inner top surface of the guide track where the closed inner track 4 and the semi-closed outer track 5 are connected; a guide groove 7 is provided through the side surface of the rotating block 6; the cross section of the guide groove 7 is the same as the cross section of the guide track ; A scraper assembly 8 is slidably provided on the inner wall of the guide track; the scraper assembly 8 includes a first slider 9; a mounting shaft 10 is fixed to the bottom surface of the first slider 9; a mounting rod 11 is fixed to the bottom end of the mounting shaft 10 by fastening bolts; a scraper 12 is fixed to the bottom end of the mounting rod 11; a guide plate 13 is fixed to the scraper 12; a limit plate 14 is fixed to the surface of the first slider 9; a guide limit block 15 is fixed to the surface of the limit plate 14; the guide limit block 15 is slidably matched with the inner wall of the guide track and the inner wall of the guide groove 7; a first slide bar 16 is fixed to the side surface of the mounting shaft 10; a guide assembly 17 is rotatably provided on the inner top surface of the L-shaped mounting frame 3; the guide assembly 17 is slidably matched with the first slide bar 16.

[0043] Specifically, the four edges of the surface of the placement plate 2 are chamfered; a placement groove 18 is opened on the surface of the placement plate 2; a hard board 19 is placed on the bottom surface of the placement groove 18; the depth of the placement groove 18 is less than the thickness of the hard board 19; the inner wall of the placement groove 18 is matched with the side surface of the hard board 19; a soft board 20 is placed on the surface of the hard board 19; a heating groove 21 is opened on the bottom surface of the placement plate 2; and a heating wire plate 22 is placed inside the heating groove 21.

[0044] The working principle of this embodiment is: first, place the hard board 19 inside the placement groove 18, turn on the electric heating wire plate 22 inside the heating groove 21, heat the inside of the glue storage box 1 to prevent the glue from solidifying, then apply glue to the surface of the hard board 19, and place the soft board 20 on the surface of the hard board 19 for pressing. Some of the excess glue flows out from the gap between the hard board 19 and the soft board 20, and flows into the glue storage box 1 along the surroundings of the placement board 2 for recycling. At this time, the glue scraping assembly 8 is located on the closed inner track 4.

[0045] like Fig.16As shown in the trajectory diagram, the motor drives the rotating block 6 to rotate so that the rotating block 6 is in Fig.16 After reaching the state shown, it stops, the guide groove 7 aligns the closed inner track 4 with one end of the semi-enclosed outer track 5, and drives the scraper assembly 8 from the starting point through the guide assembly 17, and slowly moves along the closed inner track 4, so that the guide limit block 15 slides along the closed inner track 4, and then drives the limit plate 14, the first slider 9, the mounting shaft 10, the mounting rod 11 and the scraper 12 to move slowly. During the process, the scraper 12 is close to the hard plate 19 and the soft plate 20, and the small amount of glue remaining thereon is scraped off, and the glue flows into the glue storage box 1 along the drainage plate 13. The scraper assembly 8 rotates one circle along the hard plate 19 and the soft plate 20, and then scrapes off one circle of glue, and finally stays at the end position of the semi-enclosed outer track 5. At this time, the scraper 12 is separated from the hard plate 19 and the soft plate 20, and the scraping of the glue is completed.

[0046] In this embodiment, the scraper assembly 8 is set on the guide track so that the scraper assembly 8 moves along the inner wall of the guide track. During the process, the scraper 12 is close to the side of the hard board 19 and the soft board 20 to scrape off the excess glue on the hard board 19 and the soft board 20. The glue flows into the glue storage box 1 along the drainage plate 13 to achieve the removal and recycling of the glue.

[0047] For specific embodiment 2, please refer to Figure 1-19 On the basis of the first specific embodiment, the guide assembly 17 includes a mounting block 23; a first U-shaped plate 24 and a second U-shaped plate 25 are symmetrically fixed on two opposite sides of the mounting block 23; a first slider 9 is slidably arranged on the inner wall of the first U-shaped plate 24; a coating assembly 26 is slidably arranged on the inner wall of the second U-shaped plate 25; a rotating shaft 27 is fixed on the surface of the mounting block 23; a limiting plate 28 is fixed on the top of the rotating shaft 27; a rotating groove 29 rotatably matched with the rotating shaft 27 is provided on the inner top surface of the L-shaped mounting frame 3; a limiting groove 30 rotatably matched with the limiting plate 28 is provided on the inner top surface of the rotating groove 29.

[0048] Specifically, a first slide cylinder 31 is fixed to the bottom surface of the mounting block 23; the first slide rod 16 is slidably matched with the inner wall of the first slide cylinder 31; a reciprocating screw 32 facing vertically downward is fixed to the side surface of the first slide cylinder 31; a slip ring 33 is arranged on the side surface of the reciprocating screw 32; a guide slider matched with the thread groove of the reciprocating screw 32 is arranged on the inner wall of the slip ring 33; a U-shaped limiting shaft 34 is fixed to the top surface of the limiting groove 30; a through groove 35 is opened on the surface of the limiting plate 28; the through groove 35 extends to the rotating shaft 27 and passes through the reciprocating screw 32; the U-shaped limiting shaft 34 is matched with the inner wall of the through groove 35; the slip ring 33 and the U-shaped limiting shaft 34 are penetrated and slidably matched.

[0049] The working principle of this embodiment is: the guide assembly 17 is driven by a motor to rotate, thereby driving the first U-shaped plate 24 to rotate, and then driving the coating assembly 26 to rotate, thereby driving the first slider 9 to slide along the inner wall of the first U-shaped plate 24, thereby driving the scraper assembly 8 to move as a whole, thereby driving the guide limit block 15 to slide along the inner wall of the guide track, thereby driving the scraper assembly 8 to slide along the inner wall of the guide track at the same time, thereby enabling the scraper assembly 8 to scrape off excess glue on the hard plate 19 and the soft plate 20. During the movement of the scraper assembly 8, the first slide bar 16 slides along the inner wall of the first slide cylinder 31. The first slide bar 16 and the first slide cylinder 31 play a guiding and limiting role on the scraper assembly 8, so that the scraper 12 is always facing the hard plate 19 and the soft plate 20, thereby achieving successful scraping of the glue.

[0050] For specific embodiment 3, please refer to Figure 1-19 On the basis of the first and second specific embodiments, the coating assembly 26 includes a second slider 36 that slides with the inner wall of the second U-shaped plate 25; a mounting plate 37 is symmetrically fixed on the surface and bottom of the second slider 36; an arc groove 38 is provided on the inner top surface of the L-shaped mounting frame 3; the arc groove 38 is composed of two inner ring grooves and an outer ring groove with different diameters, the inner ring groove and the outer ring groove are tangent and connected to each other, and the two ring grooves deviate from the center of the inner top surface of the L-shaped mounting frame 3; a guide ball 39 that matches the inner wall of the arc groove 38 is fixed on the surface of the mounting plate 37 located on the surface of the second slider 36; a piston rod 40 is fixed on the bottom surface of the mounting plate 37 located on the bottom surface of the second slider 36; a piston plate 41 is fixed on the bottom end of the piston rod 40; a piston cylinder 42 that slides with the piston rod 40 is slidably provided on the peripheral side of the piston plate 41.

[0051] Specifically, an L-shaped glue extraction tube 43 is fixedly passed through the bottom end of the piston cylinder 42; one end of the L-shaped glue extraction tube 43 is connected with the interior of the piston cylinder 42, and the other end thereof extends to the interior of the glue storage box 1; an L-shaped glue outlet tube 44 is fixedly passed through the side surface of the piston cylinder 42 near the top end; one end of the L-shaped glue outlet tube 44 is connected with the interior of the piston cylinder 42, and the other end thereof faces the surface of the hard plate 19; a second slide cylinder 45 is fixedly passed through the side surface of the piston cylinder 42; a second slide rod 46 is slidably provided on the inner wall of the second slide cylinder 45; a driven ring 47 is fixedly provided on the end of the second slide rod 46; the driven ring 47 is rotatably matched with the slide ring 33.

[0052] Furthermore, one-way valves are provided on the L-shaped glue extraction tube 43, the L-shaped glue outlet tube 44 and the piston plate 41, so that glue can only enter the cavity of the piston cylinder 42 located below the piston plate 41 from the L-shaped glue extraction tube 43, and the glue in the cavity of the piston cylinder 42 located above the piston plate 41 can only flow into the L-shaped glue outlet tube 44 and flow out from the end of the L-shaped glue outlet tube 44 and drip onto the surface of the hard plate 19.

[0053] The working principle of this embodiment is: during the rotation of the guide component 17, the second U-shaped plate 25 is driven to rotate, which in turn drives the second slider 36 to move, which in turn drives the mounting plate 37 to move, which in turn drives the guide ball 39 to slide along the inner wall of the arc groove 38, and then drives the coating component 26 to move along the trajectory of the arc groove 38 as a whole, so that the coating component 26 drips glue on the surface of the hard board 19.

[0054] Since the two annular grooves of the arc groove 38 deviate from the center of the inner top surface of the L-shaped mounting frame 3, the distances between the positions of the annular grooves and the center of the inner top surface of the L-shaped mounting frame 3 are different, which is similar to the shape of a spiral line. Therefore, the coating component 26 gradually shrinks inward or expands outward during the movement, so that the glue is applied in a spiral line on the surface of the hard board 19, increasing the coating area of ​​the glue, thereby optimizing the bonding effect between the hard board 19 and the soft board 20.

[0055] like Fig.15 as well as Fig.16 As shown, the inner ring groove is composed of an inner ring groove a and an inner ring groove b, and the outer ring groove is composed of an outer ring groove a and an outer ring groove b. A baffle is arranged on the top surface of the arc groove 38, and a motor is installed on the surface of the L-shaped mounting frame 3. The motor drives the baffle to rotate. When the baffle rotates to the position Fig.15 In the state shown, the running track of the coating assembly 26 is from the starting point 'sliding from the inner ring groove b into the outer ring groove a and stopping at the end point '. Fig.16 In the state shown, the running track of the coating assembly 26 is from the starting point 'sliding from the outer ring groove b into the inner ring groove a and stopping at the end point '.

[0056] During the rotation of the guide assembly 17, the reciprocating screw 32 is driven to rotate, which in turn drives the guide slider in the slip ring 33 to slide along the threaded groove of the reciprocating screw 32, which in turn drives the slip ring 33 to move up and down along the U-shaped limit shaft 34, which in turn drives the driven ring 47 to move up and down, which in turn drives the second slide rod 46 to move up and down, which in turn drives the second slide cylinder 45 to move up and down, which in turn drives the piston cylinder 42 to move up and down, and thus the piston plate 41 moves back and forth up and down relative to the piston cylinder 42.

[0057] When the baffle is Fig.15In the state shown, the trajectory of the coating assembly 26 is gradually expanding outward, and the slip ring 33 moves downward along the U-shaped limit shaft 34, thereby driving the piston cylinder 42 to move downward, and then the piston plate 41 moves upward relative to the piston cylinder 42, so that the L-shaped glue extraction tube 43 draws the glue in the glue storage box 1 into the cavity of the piston cylinder 42 located below the piston plate 41, and at the same time squeezes the glue in the cavity of the piston cylinder 42 located above the piston plate 41 into the L-shaped glue outlet tube 44 and out of the L-shaped outlet The glue flows out from the end of the hose 44 and drips onto the surface of the hard board 19, forming a spiral line trajectory that expands outward. At the same time, the trajectory of the scraper assembly 8 moves from the starting point of the semi-enclosed outer track 5 to the end point of the closed inner track 4, from away from the hard board 19 and the soft board 20 to close to the hard board 19 and the soft board 20, and then the soft board 20 is placed on the surface of the hard board 19 and pressed together. A part of the excess glue flows out from the gap between the hard board 19 and the soft board 20, and flows into the glue storage box 1 along the surroundings of the placement board 2 for recycling.

[0058] Then as Fig.16 As shown, the baffle is in this state, and the running trajectory of the coating component 26 is gradually shrinking inward, while the slip ring 33 moves upward along the U-shaped limit shaft 34, thereby driving the piston cylinder 42 to move upward, and then the piston plate 41 moves downward relative to the piston cylinder 42, and then the glue in the cavity of the piston cylinder 42 below the piston plate 41 is squeezed into the cavity of the piston cylinder 42 above the piston plate 41, and at the same time, the running trajectory of the scraper component 8 is to move one circle from the starting point along the closed inner track 4, scrape off the excess glue on the hard plate 19 and the soft plate 20, and finally stop at the end point of the semi-closed outer track 5.

[0059] In this embodiment, the coating component 26 is driven by the guide component 17 to move along the arc groove 38, so that the glue shows traces of spiral lines on the hard board 19, thereby increasing the coating area of ​​the glue, thereby improving the bonding effect between the hard board 19 and the soft board 20. At the same time, the reciprocating screw 32 of the guide component 17 rotates to drive the slip ring 33 to move up and down, and then drives the piston cylinder 42 to move up and down, thereby realizing automatic glue addition by the coating component 26.

[0060] A method for producing a coating device for processing a rigid-flexible board, characterized in that:

[0061] T1. First, place the hard board 19 inside the placement slot 18, and turn on the electric heating wire plate 22 to heat it to prevent the glue from solidifying;

[0062] T2, then drive the guide assembly 17 to rotate, during which the second U-shaped plate 25 rotates, thereby driving the coating assembly 26 to move, thereby driving the guide ball 39 to slide along the inner wall of the arc groove 38, thereby driving the coating assembly 26 to move along the trajectory of the arc groove 38 as a whole, so that the coating assembly 26 drips the glue on the surface of the hard board 19 in a spiral line that expands outward, and then puts the soft board 20 on the surface of the hard board 19 for pressing.
