[0032] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.
[0033] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0034] Reference Figures 1 to 4 This utility model discloses a flexible board bending fixture, including a base 100, a pressure block 200, a first bending plate 300 and a second bending plate 400. The base 100 is provided with a support part 110. The base 100 is provided with mounting grooves on both the left and right sides of the support part 110. A first hinge shaft and a second hinge shaft are respectively provided in the two mounting grooves. One end of the first bending plate 300 is connected to the base 100 through the first hinge shaft, so that the other end of the first bending plate 300 can swing upward around the first hinge shaft. One end of the second bending plate 400 is connected to the base 100 through the second hinge shaft, so that the other end of the second bending plate 400 can swing upward around the second hinge shaft.
[0035] It is understood that the support portion 110 is cuboid, and has a left side, a side, and a top surface. The length directions of the first hinge axis and the second hinge axis are parallel to the front-rear direction. The other end of the first bending plate 300 can swing upward around the central axis of the first hinge axis, thereby allowing the first bending plate 300 to move closer to or away from the left side of the support portion 110. The other end of the second bending plate 400 can swing upward around the central axis of the second hinge axis, thereby allowing the second bending plate 400 to move closer to or away from the right side of the support portion 110.
[0036] Reference Figure 2 and Figure 3 The pressure block 200 is vertically mounted above the base 100. The pressure block 200 has a pressing part 210, which is located above the support part 110. The pressure block 200 has a groove 220 above the pressing part 210. When the pressure block 200 is driven to rise and is above the support part 110, the middle part of the flexible board 10 to be bent can be placed on the support part 110. Then, when the pressure block 200 is driven to fall, the pressing part 210 presses the middle part of the flexible board 10 onto the upper surface of the support part 110, fixing the flexible board 10 on the support part 110 and shaping the middle part of the flexible board 10.
[0037] The first bending plate 300 includes a first bending surface 310. When the other end of the first bending plate 300 swings upward, the first bending surface 310 bends the left end of the flexible plate 10 toward the left side of the pressing part 210. The first bending surface 310 presses the left end of the flexible plate 10 against the left side of the pressing part 210, thereby bending the left end of the flexible plate 10.
[0038] The second bending plate 400 includes a second bending surface 410 and a protrusion 420 provided on the second bending surface 410. When the other end of the second bending plate 400 swings upward, the second bending surface 410 bends the right end of the flexible plate 10 toward the right side of the pressing part 210. The second bending surface 410 presses the right end of the flexible plate 10 against the right side of the pressing part 210, thereby bending the left end of the flexible plate 10. The protrusion 420 bends the right end of the flexible plate 10 toward the groove 220, thereby bending the right end of the flexible plate 10.
[0039] The first bending plate 300 and the second bending plate 400 bend the left and right ends of the flexible plate 10 upwards, so that the flexible plate 10 is U-shaped as a whole. The left and right ends of the flexible plate 10 are bent by the first bending plate 300 and the second bending plate 400, which can avoid wear on the surface of the flexible plate 10 and improve the pass rate of bending the flexible plate 10.
[0040] Reference Figure 3 The first bending surface 310 is provided with a first limiting protrusion 311, which is used to abut against the left side of the support portion 110. When the other end of the first bending plate 300 swings upward and approaches the left side of the support portion 110 and the left side of the pressing portion 210, the first limiting protrusion 311 abuts against the left side of the support portion 110, so that there is a gap between the first bending surface 310 and the left side of the support portion 110, that is, there is a gap between the first bending surface 310 and the left side of the pressing portion 210. This gap allows the left end of the flexible plate 10 to pass through, avoiding damage to the flexible plate 10 caused by excessive clamping of the flexible plate 10 by the left side of the first bending surface 310 and the pressing portion 210. Moreover, the first limiting protrusion 311 has a first inclined surface that is inclined towards the pressing portion 210. The first inclined surface has the function of guiding and shaping the flexible plate 10, making the bending part of the flexible plate 10 smoother.
[0041] Reference Figure 3 Similarly, the second bending surface 410 is provided with a second limiting protrusion 411, which is used to abut against the right side of the support portion 110. When the other end of the second bending surface 410 swings upward and approaches the right side of the support portion 110 and the right side of the pressing portion 210, the second limiting protrusion 411 abuts against the right side of the support portion 110, so that there is a gap between the second bending surface 410 and the right side of the support portion 110, that is, there is a gap between the second bending surface 410 and the right side of the pressing portion 210. This gap allows the right end of the flexible plate 10 to pass through, avoiding damage to the flexible plate 10 caused by excessive clamping of the flexible plate 10 by the right side of the second bending surface 410 and the pressing portion 210. Moreover, the second limiting protrusion 411 has a second inclined surface that is inclined towards the pressing portion 210. The second inclined surface has the function of guiding and shaping the flexible plate 10, making the bending part of the flexible plate 10 smoother.
[0042] Reference Figure 1 or Figure 4 In some embodiments, the flexible board bending fixture also includes a first handle 500, which is used to drive the pressure block 200 to rise and fall so that the pressing part 210 can press the middle part of the flexible board 10 onto the upper surface of the support part 110. The first handle 500 enables convenient and quick operation of the pressure block 200.
[0043] In some embodiments, the flexible board bending fixture also includes a support frame 600, and the pressure block 200 is connected to the support frame 600 through a sliding mechanism. The support frame 600 supports the sliding mechanism and the pressure block 200, and the sliding mechanism guides the pressure block 200 to rise and fall.
[0044] Reference Figure 1 or Figure 2 or Figure 4 In some embodiments, the sliding mechanism includes a guide rod 700 and a guide sleeve that cooperate with each other. The axial directions of the guide rod 700 and the guide sleeve are parallel to the vertical direction. The guide sleeve is connected to the support frame 600, which supports and positions the guide sleeve. The lower end of the guide rod 700 is connected to the pressure block 200, and the upper end of the guide rod 700 is connected to the first handle 500. Under the guidance of the guide rod 700 and the guide sleeve, the first handle 500 drives the pressure block 200 to rise and fall through the guide rod 700.
[0045] Understandably, the support frame 600 includes a base plate, a vertical plate, and a horizontal plate. The lower and upper ends of the vertical plate are connected to one end of the base plate and one end of the horizontal plate, respectively. The base plate, vertical plate, and horizontal plate form a U-shaped structure. The base 100 is located on the upper surface of the base plate. The horizontal plate has mounting holes. A guide sleeve passes through the mounting holes and connects to the horizontal plate. The horizontal plate supports and positions the guide sleeve. The upper end of the guide rod 700 is located above the horizontal plate and connected to the first handle 500. The lower end of the guide rod 700 is located below the horizontal plate and connected to the pressure block 200.
[0046] Reference Figure 1 and Figure 4 In some embodiments, one end of the first handle 500 is provided with a support plate portion 510 perpendicular to the first handle 500. The end of the support plate portion 510 away from the first handle 500 is hinged to the upper end of the guide rod 700. One end of the first handle 500 is hinged to a connecting rod 800, which is hinged to the support frame 600. The other end of the first handle 500 serves as an operating part. When the other end of the first handle 500 is driven to swing upward, one end of the first handle 500 drives the guide rod 700 to rise through the connecting rod 800.
[0047] It is understood that one end of the first handle 500 has two support plates 510, which are parallel to each other. The ends of the two support plates 510 away from the first handle 500 are hinged to the upper end of the guide rod 700 via a third hinge pin. The upper end of the guide rod 700 is located between the two support plates 510. There are two connecting rods 800. One end of the first handle 500 is hinged to one end of the two connecting rods 800 via a fourth hinge pin. The other ends of the two connecting rods 800 are hinged to the upper end / cross plate of the support frame 600 via a fifth hinge pin. The guide rod 700 is located between the two connecting rods 800. The third, fourth, and fifth hinge pins are parallel to each other and all parallel to the horizontal direction. The two connecting rods 800 are connected by an ear plate. The two connecting rods 800 and the ear plate are integrally formed. The first handle 500 and the two support plates 510 are integrally formed.
[0048] Reference Figure 1 In some embodiments, one of the pressure block 200 and the base 100 is provided with a cone head 230, and the other is provided with a conical blind hole 120. The cone head 230 is used to insert into the conical blind hole 120. When the pressure block 200 abuts against the base 100, the pressing part 210 presses the middle part of the flexible plate 10 down onto the upper surface of the support part 110, and the cone head 230 is inserted into the conical blind hole 120. The conical blind hole 120 serves to limit the cone head 230 in the horizontal direction, that is, to limit the relative position of the base 100 and the pressure block 200 in the horizontal direction.
[0049] In this embodiment, the cone head 230 is disposed on the lower surface of the pressure block 200, and the conical blind hole 120 is disposed on the upper surface of the base 100. There are two cone heads 230 and two conical blind holes 120.
[0050] Reference Figure 1 or Figure 4 In some embodiments, the front end of the first bending plate 300 and the front end of the second bending plate 400 are respectively connected to a second handle 320 and a third handle 430. The swing of the first bending plate 300 and the second bending plate 400 can be conveniently and quickly operated through the second handle 320 and the third handle 430, which also saves effort.
[0051] In some embodiments, the pressure block 200 or the base 100 is provided with two limiting rods 240. The two limiting rods 240 are used to limit the upper stop point of the upward swing of the second handle 320 and the third handle 430, respectively. When the second handle 320 swings upward and abuts against one limiting rod 240, the limiting rod 240 prevents the second handle 320 from swinging further. At this time, the first bending surface 310 better abuts the left end of the flexible plate 10 against the left side of the pressing part 210, and the first limiting protrusion 311 abuts against the left side of the support part 110. When the third handle 430 swings upward and abuts against another limiting rod 240, the other limiting rod 240 prevents the third handle 430 from swinging further. At this time, the second bending surface 410 better abuts the right end of the flexible plate 10 against the right side of the pressing part 210, and the second limiting protrusion 411 abuts against the right side of the support part 110.
[0052] Understandably, the two limiting rods 240 are arranged symmetrically on both sides. The second handle 320 and the third handle 430 have the same structure and are arranged symmetrically on both sides. The first bending plate 300 and the second bending plate 400 can respectively abut against the two side walls of the two mounting slots away from the center of the base 100, preventing the first bending plate 300, the second bending plate 400, the second handle 320 and the third handle 430 from lying flat, making it easier to hold the second handle 320 and the third handle 430.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
