Description

Technical Field

[0001] This utility model relates to the field of production equipment technology, and in particular to a slitting device for slitting SMD carrier tape. Background Technology

[0002] In the SMD carrier tape production process, slitting equipment needs to cut wide carrier tapes into narrow tapes of a preset width. Traditional slitting equipment typically uses a single drive shaft roller with a single blade. During the slitting process, the blade continuously cuts into the same position on the carrier tape, which easily leads to the carrier tape shifting or jamming due to uneven friction, and the slitting efficiency is low. In addition, adjusting the slitting width mostly relies on manually adjusting the carrier tape position or changing the blade spacing, which is cumbersome and prone to errors. Therefore, existing equipment suffers from insufficient slitting accuracy, high cutting resistance, and low adjustment efficiency, and there is an urgent need for a device that can simultaneously complete efficient slitting and precise adjustment.

[0025] Please see Figure 1 as well as Figure 2 A slitting device for slitting SMD carrier tapes according to an embodiment of the present invention is characterized in that it includes: a base (1), a first drive shaft (2), a second drive shaft (3), and a motor; the base is an L-shaped plate, and its vertical side plate has mounting holes for mounting the first drive shaft (2) and the second drive shaft (3); one end of the first drive shaft (2) passes through the side plate of the base and is connected to the motor for transmission; a first gear (21) is fixedly installed at the end of the first drive shaft (2) near the side plate of the base, and a first annular blade (22) is fixedly installed at the end away from the base; the second drive shaft (3) has a second gear (31) meshing with the first gear (21) at the end near the side plate of the base, and a second annular blade (32) is fixedly installed at the end away from the base; the first annular blade (22) and the second annular blade (32) are arranged alternately along the slitting direction;

[0026] Cutting principle: The motor drives the first drive shaft (2) to rotate, and the first gear (21) meshes with the second gear (31), driving the second drive shaft (3) to rotate synchronously in opposite directions; during the rotation, the first annular blade (22) and the second annular blade (32) alternately cut the carrier belt. When the first annular blade (22) cuts into the left side of the carrier belt, the second annular blade (32) cuts into the right side of the carrier belt, forming a continuous cutting trajectory to prevent the carrier belt from shifting or jamming due to uneven force on a single slice.

[0027] The vertical side plate of the L-shaped base (1) is fixed with the first drive shaft (2) and the second drive shaft (3) through the mounting holes. When the motor drives the first drive shaft (2) to rotate clockwise, the first gear (21) drives the second gear (31) meshing with it to rotate counterclockwise. The first ring blade (22) rotates clockwise with the first drive shaft (2) and cuts into the left side of the carrier belt. The second ring blade (32) rotates counterclockwise with the second drive shaft (3) and cuts into the right side of the carrier belt. The alternating cutting action of the two blades makes the carrier belt cut into segments, reducing the resistance of a single cut, and avoiding positional deviation during the movement of the carrier belt.

[0028] Please see Figure 1 as well as Figure 2 In another embodiment, a material loading device is also included, which includes: a fixed platform (4), a movable platform (5), a main shaft (6), a rotary handle (7), and a material loading platform (8); the fixed platform (4) is fixed on the surface of the machine base (1) and has a fixed hole (41); the movable platform (5) has a sliding hole (51) corresponding to the arrangement of the fixed hole, and one end of the main shaft (6) passes through the fixed platform (4) and passes through the sliding hole (51); the rotary handle (7) is fixedly connected to the main shaft (6), and when the main shaft is driven to rotate, it drives the movable platform (5) to slide laterally along the sliding hole (51); the material loading platform (8) is fixed on the movable platform (5) and is used to place the SMD carrier tape to be cut.

[0029] The fixed table (4) is fixed to the machine base (1) through the fixed hole (41). The main shaft (6) passes through the fixed table (4) and then through the sliding hole (51) of the movable table (5). When the handle (7) is turned, the main shaft (6) rotates and pushes the movable table (5) to move laterally along the sliding hole (51). The material carrier (8) moves synchronously with the movable table (5), thereby realizing the precise adjustment of the cutting width and avoiding the error caused by manually adjusting the carrier belt positioning.

[0030] Please see Figure 1 as well as Figure 2 In another embodiment, the main shaft (6) is a lead screw, the sliding hole (51) is a threaded hole, and the main shaft (6) and the movable table (5) are connected by threaded transmission.

[0031] The main shaft (6) adopts a lead screw structure, and the sliding hole (51) is provided with a thread that matches the lead screw. When the handle (7) is rotated, the lead screw meshes with the threaded hole of the movable table (5) and generates axial displacement, which converts the rotational motion into the transverse linear motion of the movable table (5) and realizes the micron-level precise adjustment of the loading table.

[0032] Please see Figure 1 as well as Figure 2 In another embodiment, the cutting edge distance between the first annular blade (22) and the second annular blade (32) is 1 / 2 to 2 / 3 of the width of the carrier tape.

[0033] The distance between the cutting edges of the first annular blade (22) and the second annular blade (32) is set to a ratio of 1 / 2 to 2 / 3 according to the width of the carrier tape. This ensures that the cutting edges of the two blades do not overlap but the distance is controllable when the two blades are cutting alternately, thus avoiding material waste and preventing burrs from being generated on the edge of the carrier tape after cutting.

[0034] Please see Figure 1 as well as Figure 2 In another embodiment, the ratio of the number of teeth of the first gear (21) to the number of teeth of the second gear (31) is 1:1.

[0035] The first gear (21) and the second gear (31) have the same number of teeth, ensuring that the rotation speed and direction of the first drive shaft (2) and the second drive shaft (3) are synchronized, so that the cutting sequence of the two annular blades is consistent and the cutting trajectory deviation is avoided.

[0036] Please see Figure 1 as well as Figure 2 In another embodiment, the first drive shaft roller (2) and the second drive shaft roller (3) are arranged in parallel and perpendicular to the cutting direction.

[0037] The first drive shaft roller (2) and the second drive shaft roller (3) are arranged in parallel and perpendicular to the cutting direction, so that the carrier belt passes evenly through the cutting area between the two blades, ensuring the straightness of the cutting surface and the stability of the carrier belt shape.

[0038] Please see Figure 1 as well as Figure 2 In another embodiment, the first annular blade (22) and the second annular blade (32) are made of cemented carbide.

[0039] The first ring blade (22) and the second ring blade (32) are made of carbide, which keeps the blade sharp during long-term slitting, reduces the frequency of replacement and improves the slitting quality.

[0040] Please see Figure 1 as well as Figure 2 In another embodiment, the first drive shaft (2) rotates in the opposite direction to the second drive shaft (3).

[0041] The first drive shaft roller (2) and the second drive shaft roller (3) rotate in opposite directions, causing the two annular blades to cut into the outer edge of the carrier belt respectively, thus counteracting the unilateral cutting force and preventing the carrier belt from shifting during the cutting process.

[0042] Please see Figure 1 as well as Figure 2 In another embodiment, the sliding contact surfaces of the movable platform (5) and the fixed platform (4) are provided with a friction-reducing coating.

[0043] A friction-reducing coating is sprayed on the sliding contact surfaces of the movable table (5) and the fixed table (4) to reduce sliding resistance and improve the smoothness of the movable table adjustment and positioning accuracy.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
