Description

Technical Field

[0001] This invention relates to the field of printed circuit board technology, and in particular to a board holder. Background Technology

[0002] A plate holder is a device used to transfer printed circuit boards. In order to accommodate printed circuit boards of different sizes, fixed limit plates and movable limit plates are usually set to limit the horizontal position of the printed circuit board. However, the mechanism for limiting the position of the movable limit plate is relatively complex, requires manual operation, and is relatively troublesome. With the popularization of automated equipment, the manual adjustment of the position of the movable limit plate will be gradually replaced, and the existing mechanism for limiting the position of the movable limit plate is not convenient for automated operation. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a plate holder that facilitates the adjustment of the position of the movable limiting plate.

[0004] According to an embodiment of the present invention, a plate holder includes a frame, a first limiting plate, a second limiting plate, and a clamping mechanism. The frame includes a left side stop and a right side stop, and a guide rod is provided across the left side stop and the right side stop. The first limiting plate is connected to the left side stop, the right side stop, or the guide rod. The clamping mechanism includes a sleeve, a handle, a push rod, and a first connecting rod. The sleeve has a communicating guide hole and a bypass hole, which are perpendicular to each other. The sleeve is connected to the second limiting plate. The guide rod passes through the guide hole, and the push rod passes through... Located in the bypass hole, one end of the handle is hinged to the second limiting plate. The handle is connected to the top rod through the first connecting rod. A first hinge point is formed between the handle and the second limiting plate, a second hinge point is formed between the handle and the first connecting rod, and a third hinge point is formed between the first connecting rod and the top rod. The first hinge point, the third hinge point, and the top rod are on a straight line. The handle can drive the top rod to be positioned against the guide rod, so that the clamping mechanism and the second limiting plate are positioned on the guide rod.

[0005] It has at least the following beneficial effects:

[0006] When the second hinge point is on one side of the straight line of the top rod, the handle can be easily rotated. The handle drives the top rod to move towards the guide hole through the bypass hole via the first connecting rod until the top rod is firmly against the guide rod. At this point, the second hinge point moves to the other side of the straight line of the top rod, and the handle is at its dead point. When no external force is applied to the handle, the handle fixes the position of the top rod, and the clamping mechanism holds the guide rod, thus fixing the clamping mechanism and the second limiting plate to the guide rod. When the handle is rotated in the opposite direction, the second hinge point returns to one side of the straight line of the top rod, and the handle drives the top rod away from the guide rod. The clamping mechanism releases the guide rod, and the clamping mechanism and the second limiting plate can move away from or closer to the first limiting plate under the guidance of the guide rod. The second limiting plate is a movable limiting plate, allowing adjustment of the distance between the first and second limiting plates, thus making the insert holder suitable for printing plates of different lengths and widths. Rotating the handle allows the top rod to move away from or against the guide rod, thereby fixing or adjusting the position of the second limiting plate. The operation is simple, convenient, and quick.

[0007] According to some embodiments of the present invention, the clamping mechanism further includes a first elastic member, the two ends of which are respectively connected to the second limiting plate and the handle / first connecting rod, and the first elastic member forces the top rod to abut against the guide rod.

[0028] Reference Figure 1 The present invention discloses a plate holder, including a frame 100 and a first limiting plate 300, a second limiting plate 400 and a clamping mechanism 500, all disposed on the frame 100.

[0029] The frame 100 includes a left side stop 110, a right side stop 120, and at least two bottom rods 130. All bottom rods 130 are distributed in the left-right direction, and the length direction of all bottom rods 130 is in the front-back direction. All bottom rods 130 have multiple first limiting grooves distributed in the front-back direction. The sides of the first limiting plate 300 and the second limiting plate 400 opposite each other are provided with second limiting grooves. The first limiting grooves and the second limiting grooves are arranged opposite each other. The left and right ends of the printing plate can be inserted into two second limiting grooves from top to bottom, and the lower end of the printing plate can be inserted into the first limiting groove corresponding to the second limiting groove from top to bottom.

[0030] The left side stop 110 and the right side stop 120 are connected by multiple crossbars, and the front and rear ends of the bottom rod 130 are respectively connected to two crossbars distributed at the front and rear. The frame 100 includes four support rods, with the upper ends of two adjacent support rods connected by crossbars, and the lower ends of two adjacent support rods also connected by crossbars. Both the left side stop 110 and the right side stop 120 include two support rods and two crossbars.

[0031] A guide rod 200 is provided across the left side stop 110 and the right side stop 120; the first limiting plate 300 is connected to the left side stop 110, the right side stop 120, or the guide rod 200; see also Figures 2 to 4 The clamping mechanism 500 includes a clamping sleeve 510, a handle 520, a push rod 530, and a first connecting rod 540. The clamping sleeve 510 has a connecting guide hole 511 and a bypass hole 512, which are perpendicular to each other. The clamping sleeve 510 is connected to the second limiting plate 400. The guide rod 200 passes through the guide hole 511, and the push rod 530 passes through the bypass hole 512. One end of the handle 520 is hinged to the second limiting plate 400, and the handle 520 is connected to the first connecting rod. 540 is connected to the top rod 530. The handle 520 forms a first hinge point with the second limiting plate 400, the handle 520 forms a second hinge point with the first connecting rod 540, and the first connecting rod 540 forms a third hinge point with the top rod 530. The first hinge point, the third hinge point and the top rod 530 are in a straight line. The handle 520 can drive the top rod 530 to be positioned against the guide rod 200, so that the clamping mechanism 500 and the second limiting plate 400 are positioned on the guide rod 200.

[0032] When the second hinge point is on one side of the straight line of the top rod 530, the handle 520 can be easily rotated. The handle 520 drives the top rod 530 to move in the bypass hole 512 toward the guide hole 511 through the first connecting rod 540 until the top rod 530 is tightly pressed against the guide rod 200. Then the second hinge point moves to the other side of the straight line of the top rod 530. When the handle 520 is at a dead point and no external force is applied to the handle 520, the handle 520 fixes the position of the top rod 530. The clamping mechanism 500 clamps the guide rod 200, thereby fixing the clamping mechanism 500 and the second limiting plate 400 on the guide rod 200.

[0033] When the handle 520 is rotated in the opposite direction, the second hinge point is reset to one side of the straight line where the top rod 530 is located. The handle 520 drives the top rod 530 away from the guide rod 200, and the clamping mechanism 500 releases the guide rod 200. The clamping mechanism 500 and the second limiting plate 400 can move away from or closer to the first limiting plate 300 under the guidance of the guide rod 200. The second limiting plate 400 is a movable limiting plate, which realizes the adjustment of the distance between the first limiting plate 300 and the second limiting plate 400, thereby making the plate holder suitable for printing plates of different length and width specifications.

[0034] Rotating the handle 520 will move the top rod 530 away from or against the guide rod 200, thereby fixing the position of the second limit plate 400 or adjusting the position of the second limit plate 400. The operation method is simple, convenient and quick.

[0035] The handle 520 is connected to one end of the first connecting rod 540 via a first hinge shaft, and the other end of the first connecting rod 540 is connected to one end of the push rod 530 via a second hinge shaft. The other end of the push rod 530 faces the guide hole 511 and the guide rod 200. The first hinge shaft and the second hinge shaft are parallel to each other.

[0036] See Figure 3 In some embodiments, the clamping mechanism 500 further includes a first elastic element 550, the two ends of which are connected to the second limiting plate 400 and the handle 520 / first connecting rod 540, respectively. The first elastic element 550 forces the push rod 530 against the guide rod 200, so that in its natural state, the push rod 530 always abuts against the guide rod 200, keeping the clamping mechanism 500 clamped on the guide rod 200 and ensuring that the positions of the first limiting plate 300 and the second limiting plate 400 are fixed. The first elastic element 550 can prevent the handle 520 from rotating in the opposite direction, thereby preventing the clamping mechanism 500 from releasing the guide rod 200.

[0037] In some embodiments, the clamping mechanism 500 further includes a stop 560, a second connecting rod 570, and a slide rod 580. The stop 560 is connected to the second limiting plate 400, so that the positions of the stop 560 and the handle 520 are relatively fixed. The stop 560 is provided with a storage groove 561. A first elastic member 550 is disposed in the storage groove 561. One end of the slide rod 580 passes through the storage groove 561 and abuts against the first elastic member 550. The slide rod 580 can slide in the storage groove 561. The storage groove 561 serves to guide the slide rod 580 and limit the first elastic member 550. The other end of the slide rod 580 is connected to the handle 520 through the second connecting rod 570. The first elastic member 550 acts on the handle 520 through the slide rod 580 and the second connecting rod 570.

[0038] Understandably, the middle section of the handle 520 is connected to one end of the second link 570 via the third hinge pin, and the other end of the second link 570 is connected to the other end of the slide rod 580 via the fourth hinge pin. The first, second, third, and fourth hinge pins are parallel to each other. The other end of the handle 520 is the grip portion, which drives the handle 520 to rotate around the first hinge pin.

[0039] In some embodiments, the clamping mechanism 500 further includes a mounting plate 590, the sleeve 510 and the stop 560 are both connected to the second limiting plate 400 through the mounting plate 590, and the handle 520 is hinged to the second limiting plate 400 through the mounting plate 590.

[0040] Mounting plate 590 serves to support the first hinge pin, second hinge pin, third hinge pin, fourth hinge pin, clamp 510, handle 520, push rod 530, first connecting rod 540, first elastic element 550, stop block 560, second connecting rod 570 and slide rod 580. The clamping mechanism 500 can be quickly and easily connected to the second limiting plate 400 through mounting plate 590.

[0041] In some embodiments, the number of guide rods 200, sleeves 510, handles 520, top rods 530, first connecting rods 540, first elastic elements 550, second connecting rods 570, and slide rods 580 are all two, and the two guide rods 200, two sleeves 510, two handles 520, two top rods 530, two first connecting rods 540, two first elastic elements 550, two second connecting rods 570, two slide rods 580, and stop blocks 560 are arranged symmetrically in the upper and lower parts.

[0042] A clamping group consists of one clamping sleeve 510, one handle 520, one push rod 530, one first connecting rod 540, one first elastic element 550, one second connecting rod 570, one slide rod 580, and half of the stop block 560. Another clamping group consists of another clamping sleeve 510, another handle 520, another push rod 530, another first connecting rod 540, another first elastic element 550, another second connecting rod 570, another slide rod 580, and the other half of the stop block 560. The clamping group and the other clamping group are symmetrically arranged with the middle part of the stop block 560 as the plane of symmetry. The two clamping groups clamp the two guide rods 200 respectively. The stability of the clamping mechanism 500 is improved by the two clamping groups and the two guide rods 200.

[0043] The sleeve 510, push rod 530, first connecting rod 540, handle 520, second connecting rod 570, slide rod 580, and stop block 560 are arranged in sequence. The sleeve 510, push rod 530, first connecting rod 540, handle 520, second connecting rod 570, slide rod 580, and stop block 560 are roughly on the same straight line.

[0044] In some embodiments, there are four guide rods 200 arranged in a rectangular shape, and two clamping mechanisms 500. The two mounting plates 590 of the two clamping mechanisms 500 are respectively connected to the front and rear ends of the second limiting plate 400. The two clamping groups of the clamping mechanisms 500 clamp the two vertically distributed guide rods 200 respectively. The front and rear ends of the second limiting plate 400 are fixed to the frame 100 through the four clamping groups and the four guide rods 200.

[0045] See Figure 1 There are four guide rods 200 in total. The crossbar between the upper ends of the two front support rods is a guide rod 200. The crossbar between the upper ends of the two rear support rods is a guide rod 200. The crossbar between the upper ends of the two rear support rods is a guide rod 200. The crossbar between the upper ends of the two rear support rods is a guide rod 200.

[0046] In some embodiments, a U-shaped plate is provided on the mounting plate 590, and the mounting plate 590 and the U-shaped plate form a clamping sleeve 510. A guide hole 511 is formed on the mounting plate 590 and the U-shaped plate. The clamping sleeve 510 and the guide hole 511 are formed by fixing the U-shaped plate to the mounting plate 590. The U-shaped plate is provided on the bypass hole 512. When installing the clamping mechanism 500, the mounting plate 590 and the U-shaped plate can be placed on both sides of the guide rod 200 respectively, so that the mounting plate 590 and the U-shaped plate clamp the guide rod 200, and then the mounting plate 590 and the U-shaped plate are connected together by fasteners.

[0047] The cross-sections of the guide rod 200 and the guide hole 511 are matched, allowing the guide rod 200 to slide within the guide hole 511. Both the cross-sections of the guide rod 200 and the guide hole 511 can be circular or rectangular.

[0048] In some embodiments, the mounting plate 590 is provided with a connecting plate 591, the connecting plate 591 is provided with a guide sleeve, and the push rod 530 passes through the central hole of the guide sleeve, the guide sleeve serves to limit the movement direction of the push rod 530.

[0049] When installing the clamping mechanism 500, the push rod 530 can be inserted into the center hole of the guide sleeve and then fixed to the mounting plate 590 by fasteners.

[0050] The connecting plate 591 is provided with a fifth hinge pin, which is parallel to the first hinge pin. The handle 520 is hinged to the connecting plate 591 through the fifth hinge pin, which means that the handle 520 is hinged to the mounting plate 590 / second limiting plate 400. One end of the fifth hinge pin is located on the ear plate, and the diameter of the ear plate is larger than the diameter of the fifth hinge pin. The ear plate is located between the mounting plate 590 and the connecting plate 591, thereby limiting the position of the fifth hinge pin.

[0051] In some embodiments, the second link 570 is curved, and the handle 520 is provided with a limiting rod 521. When the handle 520 is rotated, the handle 520 drives the second link 570 to swing. The back of the second link 570 can abut against the limiting rod 521, thereby preventing the second link 570 from continuing to swing, thus limiting the rotation range of the handle 520 and the stroke of the push rod 530.

[0052] The central axis of the handle 520 along its length is perpendicular to and intersects with the fifth hinge. The handle 520 is provided with a protruding plate. The limiting rod 521 and the first hinge are parallel to each other and are both provided on the protruding plate. The line connecting the limiting rod 521 and the first hinge is parallel to the central axis of the handle 520 along its length. The back of the second connecting rod 570 faces the other end of the handle 520.

[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, the present invention 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 the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
