Description

Technical Field

[0001] The present invention relates to a supporting device for a board rack for fixing a flexible board in a process of manufacturing a flexible board, and in particular to a board rack supporting device which can avoid dust generated due to friction between the board rack and the platform and affect the cleanliness of the production environment during the process of placing the board rack on or taking out the platform. Background Art

[0002] The IC carrier is a circuit board on which the chip is mounted, that is, the carrier of the chip. When the chip is installed, the circuit inside the IC carrier is used to connect the signal between the chip and the printed circuit board (PCB). The IC carrier is very small and thin (about 0.2 to 0.4 mm), flexible, and is a high-precision circuit board.

[0003] Since IC carriers are too soft, they need to be fixed on a rack and then transported together with the rack during the manufacturing process. In practice, multiple racks with IC carriers fixed on them are usually transported to a flexible board carrier for storage and arrangement until a predetermined number of racks are accumulated, and then the flexible board carrier is transported to the next predetermined process area. In addition, other flexible circuit boards and flexible board bodies also need to be transported with racks during the manufacturing process.

[0004] The structure of the conventional plate rack carrying device is that a plurality of carrying slots are arranged on a carrier, and the carrying slots are U-shaped or V-shaped. When the plate rack is transported to the carrier, the plate rack is put down so that the protrusion formed on the side of the plate rack is directly placed in the carrying slot. When the plate rack is to be used, the plate rack is moved out of the carrying slot. However, when the plate rack is placed in or moved out of the carrying slot, dust will be generated due to different degrees of friction between the plate rack and the side wall and bottom of the carrying slot, which affects the cleanliness of the production environment. In particular, when the protrusion of the plate rack is placed in the carrying slot and contacts the bottom, the gravity of the plate rack will generate an impact force, resulting in greater friction and more dust. Summary of the invention

[0005] The object of the present invention is to provide a board rack carrying device, which can be used to avoid dust generated by friction between the board rack and the carrier during the process of placing or removing the board rack on or taking out the carrier when manufacturing IC carriers, flexible circuit boards or other flexible boards, thereby avoiding affecting the cleanliness of the production environment.

[0006] The plate rack bearing device provided by the present invention may include: a carrier, the upper part of which is provided with at least one bearing groove for bearing a plurality of plate racks, and the two opposite sides of the at least one bearing groove are formed with protrusions; a plurality of first rollers are rotatably arranged on each of the protrusions, and the outer diameter edges of the plurality of first rollers protrude into the at least one bearing groove; and at least one second roller is rotatably arranged at the bottom of the at least one bearing groove. Through the structure of the bearing device, when the protrusion on the side of the plate rack is placed in or taken out of the bearing groove of the carrier, it will not directly generate friction with the side wall of the bearing groove, but will form rolling contact with the roller with high hardness and low friction coefficient, thereby avoiding the generation of dust.

[0007] In one embodiment of the present invention, the carrier may include a base and side walls connected to opposite sides of the base, and the bearing grooves are respectively provided at the upper portions of the side walls. With the structure, protrusions may be formed on opposite sides of the plate frame, and the protrusions on both sides may be placed across the bearing grooves located on both sides of the carrier.

[0008] An embodiment of the present invention may further include: an upper roller seat, which is arranged at the upper end of the side wall, and at least one of the bearing grooves and the plurality of protrusions is formed on the upper roller seat. Through the structure, the bearing grooves and protrusions can be pre-fabricated on the upper roller seat, and then the upper roller seat is mounted on the side wall of the carrier, so as to simplify the manufacturing process.

[0009] In one embodiment of the present invention, a plurality of the bearing grooves may be arranged in a straight line, the central axes of the plurality of first rollers provided on the plurality of protrusions are parallel to the longitudinal axis of the at least one bearing groove, and the central axis of the at least one second roller is perpendicular to the longitudinal axis of the at least one bearing groove. Through the structure, when the protrusion of the plate rack is placed in or taken out of the bearing groove, its side edge may have rolling contact with the first roller to be guided to be placed in or taken out of the bearing groove, and when the lower edge of the protrusion contacts the second roller, the plate rack may be moved in the horizontal direction on the rotatable second roller to adjust the position of the plate rack.

[0010] According to one embodiment of the present invention, two of the first rollers and one of the second rollers may be configured as a group, wherein the central axes of the first rollers disposed on the plurality of protrusions are parallel to the longitudinal axis of the bearing groove, and the central axis of the second roller is perpendicular to the longitudinal axis of the bearing groove.

[0011] In one embodiment of the present invention, a buffer assembly is respectively disposed in opposite sides of the at least one bearing groove, and both ends of the wheel shaft of the at least one second roller are respectively acted upon by the buffer assembly to absorb impact force. With the structure, when the protruding portion of the plate frame is placed in the bearing groove and contacts the second roller, the impact force is absorbed by the buffer assembly to reduce friction, thereby minimizing the probability of dust generation.

[0012] The buffer component may be a spring; or any appropriate elastic component.

[0013] In one embodiment of the present invention, a lower roller seat can be arranged on the base, and at least one positioning groove for positioning the plate frame is arranged on the lower roller seat, and positioning blocks are formed on opposite sides of the at least one positioning groove, and each positioning block can be rotatably provided with a positioning roller, and the outer diameter edge of the positioning roller protrudes into the positioning groove. With the structure, when the protruding part of the plate frame is placed in the bearing groove, the two sides of the lower end of the plate frame also roll with the positioning rollers and are guided into the positioning groove, so as to prevent the lower end of the plate frame from shaking due to being suspended in the air.

[0014] According to one embodiment of the present invention, a lower roller can be arranged at the bottom of the positioning groove. Through the structure, the lower side of the plate frame inserted into the positioning groove can be supported.

[0015] Preferably, the first roller, the second roller and the positioning roller used in the present invention can be made of materials with a low friction coefficient, such as quartz, glass, alloy, ceramic or plastic. BRIEF DESCRIPTION OF THE DRAWINGS
