Description

Technical Field

[0001] The utility model relates to the technical field of automatic adhesive pasting machines, and particularly to a cutting device for an automatic adhesive pasting machine. Background Technique

[0002] An automatic adhesive pasting machine is a device that can automatically complete the adhesive pasting operation and is widely used in industries such as electronics, electrical appliances, automobiles, and medical treatment. The cutting device applied to the automatic adhesive pasting machine can perform a cutting action on the adhesive tape adhered to the fixing base after adhesive pasting.

[0003] The cutting step for the adhesive tape is to use a cylinder to push the cutter into contact with the adhesive tape and use the cutter to cut the adhesive tape. However, because the adhesive tape is relatively soft and the existing cutting device does not have the ability to fix the adhesive tape, when cutting, the adhesive tape is likely to shift due to the push of the cutter, resulting in the failure of cutting the adhesive tape. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cutting device for an automatic adhesive pasting machine to solve the problems raised in the above background technique.

[0005] In view of the above problems, the technical solution proposed by the utility model is:

[0006] A cutting device for an automatic adhesive pasting machine includes a cutting member and a fixing member. The cutting member includes a base, a cylinder is installed on the top of the base, a tool holder is installed at the telescopic end of the cylinder, and a cutter head is installed on the side of the tool holder. The fixing member includes a pair of columns installed on the top surface of the base, and the pair of columns are located on both sides of the cutter head. The top ends of the columns are both installed with bottom plates, and top plates slide on the top of the bottom plates. Lifting members are installed on the sides of the columns, and the lifting members drive the top plates to move upward. A pair of descending members installed on the base are provided directly below the bottom plates, and the pair of descending members pull the top plates downward to make the top plates press against the bottom plates.

[0007] The beneficial effect of adopting the above further solution is that the descending member is used to make the top plate and the bottom plate press against each other, thereby fixing the adhesive tape between the top plate and the bottom plate. The elongation of the cylinder can make the cutter head press against the fixed adhesive tape. Since the adhesive tape is fixed by the top plate and the bottom plate, the adhesive tape will not shift when the cutter head presses against the adhesive tape, thereby ensuring that the cutter head can quickly cut the adhesive tape.

[0008] Further, each of the pair of descending members includes a connecting head installed on the top surface of the base. A disc slides inside the connecting head. A spring is connected between the bottom surface of the disc and the inner bottom surface of the connecting head. A sliding rod installed on the top surface of the disc slides inside the connecting head, and the free end of the sliding rod passes through the bottom plate and is connected to the bottom surface of the top plate.

[0009] The beneficial effect of adopting the above further solution is that in the natural state, the spring will pull the disc, causing the top plate, so that the top plate moves downward to the state of being squeezed against the bottom plate.

[0010] Furthermore, the lifting member includes a motor installed on the side of the column, and the output end of the motor is drivingly connected with an eccentric wheel, and the eccentric wheel squeezes one side of the bottom surface of the top plate.

[0011] The beneficial effect of adopting the above further solution is that the motor drives the eccentric wheel to rotate, and the eccentric wheel then squeezes one side of the bottom surface of the top plate, so that the top plate moves upward to loosen the rubber strip.

[0012] Furthermore, the diameter of the disc is the same as the inner diameter of the connecting head. First through holes are provided at the center of the top surface of the connecting head and the top surface of the bottom plate. The sliding rod slides in the first through hole, and the diameter of the sliding rod is the same as the diameter of the first through hole.

[0013] The beneficial effect of adopting the above further solution is that since the eccentric wheel squeezes one side of the bottom surface of the top plate, by restricting the diameter of the disc, the inner diameter of the connecting head, the diameter of the sliding rod, and the diameter of the first through hole, the sliding rod can maintain a vertical linear motion, so as to ensure that the top plate will not become inclined due to the influence of the squeezing position.

[0014] Furthermore, a support rod is installed on the top surface of the base, and a pressing plate is installed at the top end of the support rod.

[0015] The beneficial effect of adopting the above further solution is that the pressing plate presses the top surface of the rubber strip.

[0016] Furthermore, an opening is provided on one side of the cutter head, a notch is provided on the bottom surface of the opening, and cutting knives are installed on both sides of the notch.

[0017] Furthermore, the length of the top surface of the opening is greater than the length of its bottom surface. First inclined surfaces are provided on both sides of the opening, and a second inclined surface is provided on one side of the cutting knife, and the inclination degrees of the first inclined surface and the second inclined surface are the same.

[0018] The beneficial effect of adopting the above further solution is that a pair of cutting knives are used to cut the rubber strip. By restricting the shape and size of the opening and the shape and size of one side of the cutting knife, it can be ensured that the rubber strip smoothly slides into the opening.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the glue cutting device of the automatic glue pasting machine, a descending part is used to make the top plate and the bottom plate extrude, so as to fix the rubber strip between the top plate and the bottom plate. The elongation of the air cylinder can make the cutter head extrude the fixed rubber strip. Since the rubber strip is fixed by the top plate and the bottom plate, when the cutter head extrudes the rubber strip, the rubber strip will not shift, thereby ensuring that the cutter head can quickly cut the rubber strip.
