Description

Technical Field

[0001] The utility model relates to the technical field of material strip processing, in particular to a material strip sampling and shearing device. Background Art

[0002] Carrier Tape refers to a strip product used in the field of electronic packaging. It has a specific thickness and has holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning evenly distributed along its length.

[0003] Carrier tape is mainly used in the electronic component mounting industry. It is used with cover tape (upper sealing tape) to carry and store electronic components such as diodes in the pockets of the carrier tape, and the cover tape is sealed on the top of the carrier tape to form a closed package to protect the electronic components from contamination and damage during transportation. When the electronic components are mounted, the cover tape is peeled off, and the automatic mounting equipment takes out the components in the pocket one by one through the precise positioning of the index hole of the carrier tape, and mounts them on the integrated circuit board (PCB board).

[0004] The carrier tape is conveyed forward piece by piece during the production process, and needs to be cut for sampling and inspection during the production process. However, the existing sampling and shearing device has a limited width of the cut sample during use, and can only cut the carrier tape at a specific width position, and cannot arbitrarily cut samples of different widths according to the needs of sampling and inspection.

[0007] A further technical solution is that the angle rotation structure includes a rotating disk, a rotating shaft, a first bevel gear and a second bevel gear, the rotating shaft is rotatably connected to the mounting box, the rotating disk is connected to the rotating shaft, the first bevel gear is connected to the rotating shaft and is located in the mounting box, the second bevel gear is located at the end of the rotating circular tube, and the first bevel gear is meshed with the second bevel gear.

[0008] According to a further technical solution, two symmetrically arranged sliding grooves are provided on the rotating circular tube.

[0009] A further technical solution is that the shear adjustment structure includes an adjusting bidirectional screw rod, two adjusting blocks and two mounting blocks, the two ends of the adjusting bidirectional screw rod are respectively rotatably connected to the second bevel gear and the end of the rotating circular tube, the two ends of the adjusting bidirectional screw rod respectively extend to the outside of the mounting box and another mounting seat, the ends of the adjusting bidirectional screw rod are rotatably connected to the mounting box, both ends of the adjusting bidirectional screw rod are provided with adjusting disks, the two adjusting blocks are symmetrically connected to the adjusting bidirectional screw rod, the two adjusting blocks are respectively threadedly connected to the adjusting bidirectional screw rod, the adjusting block is slidably matched with the slide groove, the two mounting blocks are respectively connected to the two adjusting blocks, and the adjusting block is slidably matched with the rotating circular tube.

[0010] According to a further technical solution, the shear blade is arranged on the mounting block, and the shear blade and the mounting block are detachably connected.

[0011] Beneficial effects of the utility model:

[0012] Firstly, when the utility model adjusts the spacing between the two shear blades, arbitrarily rotating an adjusting disk can drive the adjusting bidirectional screw to rotate on the second bevel gear and the rotating circular tube. The rotation of the adjusting bidirectional screw will drive the two adjusting blocks to move synchronously in the two slide grooves, so that the two adjusting blocks can be synchronously approached or moved away. The movement of the positions of the two adjusting blocks will drive the positions of the two mounting blocks to move, thereby driving the spacing between the two shear blades to be adjusted, so that the spacing distance between the two shear blades can be adjusted at will during the process of shearing the carrier tape, and carrier tapes of different widths can be cut out for subsequent inspection needs.

[0022] During use, the two mounting seats 1 are installed on a machine for producing carrier tapes, and the carrier tapes are conveyed forward one by one for processing. When sampling and testing are performed, the spacing between the two shear blades 6 can be adjusted by rotating the shear adjustment structure 5. The distance between the two shear blades 6 can be adjusted according to the needs of the inspection, thereby cutting out the required carrier tape for inspection. After the adjustment is completed, the angle rotation structure 4 can be rotated to allow the rotating circular tube 2 to rotate on the two mounting blocks 53, and the positions of the two shear blades 6 are moved to the conveyed carrier tape, and the position of the carrier tape is cut to obtain the carrier tape required for inspection.

[0023] In this embodiment, refer to Figure 5 As shown, the angle rotation structure 4 includes a rotating disk 41, a rotating shaft 42, a first bevel gear 43 and a second bevel gear 44, the rotating shaft 42 is rotatably connected to the mounting box 3, the rotating disk 41 is connected to the rotating shaft 42, the first bevel gear 43 is connected to the rotating shaft 42 and is located in the mounting box 3, the second bevel gear 44 is located at the end of the rotating circular tube 2, and the first bevel gear 43 is meshed with the second bevel gear 44.

[0024] When the two shearing blades 6 are rotated onto the carrier tape to cut the carrier tape, rotating the rotating disk 41 can drive the rotating shaft 42 to rotate on the mounting box 3, thereby driving the first bevel gear 43 to rotate. The rotation of the first bevel gear 43 drives the second bevel gear 44 to rotate, thereby driving the rotating circular tube 2 to rotate on the two mounting seats 1, and the positions of the two shearing blades 6 are rotated to the carrier tape conveyed, and the carrier tape is cut so that the carrier tape can be inspected later.

[0025] In this embodiment, two symmetrically arranged sliding grooves 21 are provided on the rotating circular tube 2 .

[0027] When adjusting the spacing between the two shear blades 6, arbitrarily rotating an adjusting disk 54 can drive the adjusting bidirectional screw rod 51 to rotate on the second bevel gear 44 and the rotating tube 2. The rotation of the adjusting bidirectional screw rod 51 will drive the two adjusting blocks 52 to move synchronously in the two slide grooves 21, so that the two adjusting blocks 52 are synchronously approached or moved away. The movement of the positions of the two adjusting blocks 52 will drive the positions of the two mounting blocks 53 to move, thereby driving the spacing between the two shear blades 6 to be adjusted, so that the spacing distance between the two shear blades 6 can be adjusted at will during the process of shearing the carrier tape, and carrier tapes of different widths can be cut out for subsequent inspection needs.

[0028] In this embodiment, refer to Figure 3 As shown, the shear blade 6 is arranged on the mounting block 53, and the shear blade 6 and the mounting block 53 are detachably connected; when the shear blade 6 is replaced after being used for a period of time, the shear blade 6 can be removed from the mounting block 53.
