Description

Technical Field

[0001] The present invention relates to a clamp, in particular to a clamp with a horizontally movable clamping head which can stably clamp a plate in an upright state without damaging the clamped object. Background Art

[0002] The manufacturing process for printed circuit boards (PCBs) requires ink coating, drying, baking, and cleaning. To increase production capacity, conveyors are typically used to transport the PCBs through the various workstations involved in these processes. During this process, clamps are often used to hold the edges of the PCBs in a suspended position. Conveyor chains or belts are used to move the clamps, transporting the PCBs to the various workstations.

[0003] As in this case Figure 6 and Figure 7 The figure shows a conventional clamping member 80 that can be mounted on the rod 70 to clamp and transport the plate. The clamping member 80 includes a body 81, an arm 82, a connecting rod 83, a clamping claw 84 and a return spring 85. The body 81 has a clamping claw abutting surface 811. The arm 82 and the clamping claw 84 are respectively pivotally connected to the body 81 and connected through the connecting rod 83 to form a connecting rod mechanism. The arm 82 extends from one side of the body 81, and the two ends of the return spring 85 are respectively connected to the body 81 and the arm 82. The operator can push the arm 82 through the power device to drive the clamping claw 84 to pivot through the connecting rod mechanism, thereby forming a Figure 7 The open jaw state shown is used to clamp the plate between the jaw 84 and the jaw abutment surface 811 of the body 81, thereby achieving the effect of conveying the plate.

[0004] Likewise Figure 6 and Figure 7 As shown, the force-applying end of the aforementioned substrate clamp moves back and forth along an arcuate path during the opening and closing of the clamp. This arcuate path can easily complicate the design and control of the equipment used to automatically apply force to the force-applying end of the substrate clamp. More specifically, this arcuate path complicates the structure of the equipment used to apply force to the force-applying end. Furthermore, the serrated end surfaces of the jaws 84 of the conventional clamping member 80 can easily damage thin printed circuit boards when clamping them, potentially affecting circuit performance. Summary of the Invention

[0005] An object of the present invention is to provide a clamp with a horizontally movable clamping head that can clamp a plate in an upright state without causing damage to the plate.

[0006] The clamp for a horizontally movable chuck provided by the present invention may include: a body; a connecting rod assembly movably disposed on the body; an elastic component connecting the body and the connecting rod assembly; and a chuck including: a fixed clamping block disposed on the body; and a movable clamping block movably disposed on the body relative to the fixed clamping block and movably connected to the connecting rod assembly. That is, through the clamp for a horizontally movable chuck, when the movable clamping block is open relative to the fixed clamping block, a plate can be vertically accommodated between the movable clamping block and the fixed clamping block, and when the movable clamping block is closed relative to the fixed clamping block, the plate can be clamped and then transported by a conveying device.

[0007] In one embodiment of the present invention, the fixed clamping block has a planar first clamping surface, and the movable clamping block has a planar second clamping surface. Since both the first clamping surface and the second clamping surface are planar, the clamped plate will not be damaged.

[0008] In one embodiment of the present invention, the first clamping surface and the second clamping surface may correspond to each other, thereby enabling the plate to be clamped stably.

[0009] In one embodiment of the present invention, the fixed clamping block and the movable clamping block are both detachable and assembleable relative to the body, so that when the fixed clamping block and the movable clamping block deteriorate due to being exposed to a high temperature environment, they can be replaced more conveniently.

[0010] In one embodiment of the present invention, the fixed clamping block and the movable clamping block can be made of insulating materials such as engineering plastics, bakelite, etc.

[0011] In one embodiment of the present invention, the connecting rod group may include an end rod and a connecting rod, the end rod is a rod that receives external force to drive the connecting rod group, the connecting rod connects the end rod and the movable clamp, and the elastic component connects the end rod and the main body.

[0012] According to an embodiment of the present invention, the end rod can be pivotally mounted on the body.

[0013] In one embodiment of the present invention, the main body may include a first plate and a second plate arranged parallel to each other, the first plate and the second plate respectively forming a first horizontal guide groove and a second horizontal guide groove corresponding to each other, at least one first guide post and at least one second guide post are respectively provided on opposite sides of the movable clamp, the at least one first guide post slidably fitting within the first horizontal guide groove, and the at least one second guide post slidably fitting within the second horizontal guide groove. The first horizontal guide groove and the second horizontal guide groove respectively guide the first guide post and the second guide plate, allowing the movable clamp to maintain horizontal movement relative to the fixed clamp when approaching or separating.

[0014] According to one embodiment of the present invention, the movable clamp may include: a movable block provided with a groove, and the at least one first guide column and the at least one second guide column are respectively arranged on opposite sides of the movable block; and a plate having a lug, the plate being fixedly arranged in the groove of the movable block, and the lug protruding from the groove, wherein the two ends of the connecting rod are pivotally connected to the lug and the end rod respectively.

[0015] Preferably, the first clamping surface of the fixed clamping block and the second clamping surface of the movable clamping block are both perpendicular to the direction connecting the centers of the arcs at both ends of the first horizontal guide groove (i.e., the length direction of the first horizontal guide groove) and the direction connecting the centers of the arcs at both ends of the second horizontal guide groove (i.e., the length direction of the second horizontal guide groove). Accordingly, the first clamping surface and the second clamping surface can achieve optimal stabilization when clamping an upright panel.

[0016] Preferably, the elastic component can be a tension spring. Accordingly, the elastic component can be conveniently connected to the connecting rod assembly and the body, and is convenient for future maintenance.

[0017] The beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0028] To facilitate understanding of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. The accompanying drawings provide some, but not all, embodiments of the present invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without further effort are within the scope of protection of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] like Figures 1 to 3As shown, the horizontally movable chuck fixture provided by the present invention includes: a body 1, a connecting rod assembly 2, an elastic component 3, a fixed clamping block 4, and a movable clamping block 5. The body 1 may include a first plate 1A and a second plate 1B having mutually symmetrical profiles. The first plate 1A and the second plate 1B are arranged parallel to each other and separated by a spacer 16 and a fixed shaft 17 to form a space for accommodating the connecting rod assembly 2, the elastic component 3, the fixed clamping block 4, and the movable clamping block 5. Among them, the first plate 1A and the second plate 1B are respectively formed with a first axial hole 11A and a second axial hole 11B, a first horizontal guide groove 12A and a second horizontal guide groove 12B, a first fixing hole 13A and a second fixing hole 13B, a first positioning hole 15A and a second positioning hole 15B at mutually symmetrical positions; the spacer 16 is respectively formed with positioning protrusions 161 on opposite sides, and the positioning protrusions 161 on both sides are respectively inserted into the first positioning hole 15A and the second positioning hole 15B to separate and position the first plate 1A and the second plate 1B from each other, and at the same time, the spacer 16 is After the two ends of the fixed shaft 17 pass through the first fixing hole 13A and the second fixing hole 13B respectively, the fixed shaft 17 is fixed to the first plate 1A and the second plate 1B using a fixing cap, thereby making the first plate 1A and the second plate 1B arranged parallel to each other, thereby forming the spacing space between the first plate 1A and the second plate 1B, and positioning the first horizontal guide groove 12A and the second horizontal guide groove 12B in a horizontal position; that is, the spacer 16 arranged between the first plate 1A and the second plate 1B has the function of assisting the horizontal movement of the movable clamp. The assembled body 1 can be transported (such as) by passing the first shaft hole 11A and the second shaft hole 11B through the rod 7 of the conveying device. Figure 1 shown).

[0031] The connecting rod assembly 2 can have various embodiments. For example, it can include an end rod 20 and a connecting rod 26, wherein the end rod 20 is rotatably mounted on the main body 1. Specifically, the end rod 20 is formed with a curved force-applying end 21, and the opposite end is a force-resisting end and is formed with a first pivot hole 23. A support shaft hole 22 and a first hook hole 24 are formed between the two ends of the end rod 20. A support shaft 25 passes through the support shaft hole 22 to rotatably mount the end rod 20 on the second plate 1B. Pivot holes 261 are respectively provided at each end of the connecting rod 26. A pivot shaft 262 is movably connected to the lug 521 through the pivot hole 261 at one end and the second pivot hole 522, and another pivot shaft 262 is movably connected to the end rod 20 through the pivot hole 261 at the other end and the first pivot hole 23, thereby establishing a linkage relationship between the end rod 20 and the connecting rod 26. The connecting rod group 2 can also adopt a four-link group (not shown in the figure), in which the active connecting rod in the four-link group receives external force and moves, and then the passive connecting rod drives the movable clamp to move horizontally relative to the fixed clamp to clamp or release the plate.

[0032] The elastic component 3 is preferably a tension spring, and the hooks at both ends of the elastic component 3 respectively buckle the first hook hole 24 of the end rod 20 and one of the fixed shafts 17 provided between the first plate 1A and the second plate 1B. Accordingly, when the force-applying end of the end rod 20 is subjected to an external force, it can rotate around the support shaft 25 (such as Figure 5 As shown), the connecting rod 26 is linked, and the elastic component 3 is stretched to store elastic force; when the external force is released, the elastic force stored in the elastic component 3 restores the end rod 20 to its original shape and limits it to the initial position (as shown). Figure 4 vertical position shown).

[0033] The fixing clamp 4 is detachably fixed between the first plate 1A and the second plate 1B; specifically, the fixing clamp 4 is provided with a through hole 41 and has a first flat clamping surface 42 on one side, and the fixing clamp 4 can be fixed between the first plate 1A and the second plate 1B of the main body 1 by fixing components such as screws, and the fixing clamp 4 can be replaced by removing the fixing components such as screws; wherein, the first clamping surface 42 can be made of insulating materials such as engineering plastics, bakelite, etc.

[0034] The movable clamp 5 is detachably and movably arranged between the first plate 1A and the second plate 1B; wherein, at least one first guide column 513A and at least one second guide column 513B can be respectively arranged on opposite sides of the movable clamp 5, the at least one first guide column 513A slidingly fits in the first horizontal guide groove 12A of the first plate 1A, and the at least one second guide column 513B slidingly fits in the second horizontal guide groove 12B of the second plate 1B; the arc center line L at both ends of the first horizontal guide groove 12A and the second horizontal guide groove 12B is a horizontal line. More specifically, as Figure 2 and Figure 3As shown, in an embodiment of the present invention, the movable clamp 5 may include a movable block 51 and a plate 52; wherein, the movable block 51 is provided with a groove 511, and at least one through-hole 512 is provided on the opposite sides of the movable block 51, and the aforementioned first guide column 513A and the second guide column 513B are respectively arranged in the through-holes 512 on both sides of the movable block 51 and protrude from the through-holes 512; one end of the movable block 51 is also formed with a second clamping surface 510 which is flat and corresponds to the aforementioned first clamping surface 42, accordingly, the first clamping surface 42 and the second clamping surface 510 are both perpendicular to the direction of the arc center line L at both ends of the first horizontal guide groove 12A and the second horizontal guide groove 12B. The plate 52 is formed with a lug 521 and is provided with a second pivot hole 522 and a through hole 523. A portion of the plate 52 is inserted into the groove 511 of the movable block 51. The plate 52 is fixed to the movable block 51 using screws or other fixing components, with the lug 521 protruding from the groove 511. The second clamping surface 510 can be made of an insulating material such as engineering plastic, bakelite, etc.

[0035] It is particularly worth mentioning that since insulating materials such as bakelite, engineering plastics, etc. will deteriorate in high temperature environments and must be replaced regularly, the present invention sets both the fixed clamp block 4 and the movable clamp block 5 to be detachable for easy replacement, which is of great help to the production line.

[0036] like Figure 4 As shown, when the clamp of the present invention is actually used, when the force-applying end 21 of the end rod 20 of the connecting rod group 2 is subjected to an external force, it will rotate, thereby driving the movable clamp 5 to move via the connecting rod 26. Since the first guide column 513A and the second guide column 513B provided on the movable clamp 5 are guided by the first horizontal guide groove 12A and the second horizontal guide groove 12B respectively, the movable clamp 5 is caused to move horizontally, that is, the second clamping surface 510 and the first clamping surface 42 are moved away from each other in the horizontal straight direction and opened. At this time, the upper end edge of the vertical plate 6 (such as a circuit substrate) can be moved between the opened first clamping surface 42 and the second clamping surface 510; at the same time, in this state, the elastic component 3 is stretched by the rotation of the end rod 20 to store elastic force.

[0037] like Figure 5 As shown, when the external force acting on the force-applying end 21 of the end rod 20 is released, the elastic force stored in the elastic component 3 is also released. At this time, the elastic component 3 pulls the end rod 20 back to its initial position. At this time, the plate 6 placed between the fixed clamp 4 and the movable clamp 5 is clamped and fixed by the first clamping surface 42 and the second clamping surface 510, so that the plate 6 can be transported to the next process workstation through the conveying device.

[0038] In summary, the present invention forms a planar first clamping surface 42 on the fixed clamping block 4, a planar second clamping surface 510 on the movable clamping block 5, and a structural design in which the movable clamping block 5 moves horizontally relative to the fixed clamping block 4, so that thin and light panels will not be damaged when clamped and the stability of the clamping can be maintained.

[0039] The above-described embodiments merely represent preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various changes and modifications without departing from the scope of the present invention, and such changes and modifications are within the scope of protection of the present invention.
