Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-6 The utility model provides the following technical solutions: a material tape shearing device for an SMT splicer, comprising a workbench 3, a conveyor belt 4 is arranged inside the workbench 3, a mounting frame 2 is connected above the workbench 3, recycling mechanisms 5 are arranged on both sides of the mounting frame 2, a cleaning component 6 is arranged inside the recycling mechanism 5, a telescopic mechanism 1 is arranged above the mounting frame 2, pressing frames 7 are arranged at both ends of the lower side of the telescopic mechanism 1, an adjusting component 8 is arranged between the telescopic mechanism 1 and the pressing frame 7, and shearing mechanisms 9 are arranged at both ends of the adjusting component 8.

[0025] Specifically, the cleaning assembly 6 includes a brush 61, a push plate 62 and a push rod 63. The push rod 63 is inserted into the interior of the recovery mechanism 5. One end of the push rod 63 is connected to the push plate 62. The side wall of the push plate 62 is connected to the brush 61.

[0026] By adopting the above technical solution, the push rod 63 is held by hand to drive the push plate 62 to move, and the movement of the push plate 62 drives the brush 61 to move. During the movement of the brush 61, the film adhered to the components of the recovery mechanism 5 can be cleaned to prevent the film from adhering to the components of the recovery mechanism 5 and affecting the discharge operation of the film.

[0027] Specifically, the cleaning assembly 6 also includes an L-shaped plate 64, a moving block 65, a moving groove 66 and a support member 67. The L-shaped plate 64 is connected to the top of the recovery mechanism 5 and on one side of the push rod 63. The moving block 65 is connected to the side of the push rod 63 close to the L-shaped plate 64. A support member 67 is provided between the L-shaped plate 64 and the moving block 65. A moving groove 66 is provided on the L-shaped plate 64 at a position corresponding to the moving block 65.

[0028] By adopting the above technical solution, the push rod 63 is moved upward, and the movement of the push rod 63 drives the moving block 65 to move inside the moving groove 66. When the moving block 65 moves to fit the side wall of the moving groove 66, the moving block 65 is blocked and stops moving. The support member 67 is then used to support the moving block 65 and the L-shaped plate 64 to ensure the stability of the placement of the push rod 63, and thus the stability of the placement of the brush 61 and the push plate 62 can be ensured.

[0029] Specifically, the support member 67 includes a cavity 671, a support rod 672, a connecting spring 673, a connecting groove 674 and a fixed column 675. The L-shaped plate 64 is provided with a connecting groove 674, and the interior of the connecting groove 674 is connected to the fixed column 675. Both ends of the fixed column 675 are sleeved with support rods 672. A connecting spring 673 is connected between the two support rods 672 and located on the periphery of the fixed column 675. A cavity 671 is provided on the movable block 65 at a position corresponding to the support rod 672.

[0030] By adopting the above technical solution, the two support rods 672 are first moved toward each other along the fixed column 675, and the two support rods 672 move to squeeze the connecting spring 673. When the two support rods 672 are in contact with each other, the movement of the support rods 672 is stopped. Subsequently, after the moving block 65 moves to fit the side wall of the moving groove 66, the bottom end of the support rod 672 passes through the cavity 671 on the moving block 65, and then the support rod 672 is released. The connecting spring 673 loses the external force and returns to its original state, driving the support rod 672 to move back to fit the two side walls of the connecting groove 674. Under the action of the support rod 672, the moving block 65 can be supported to ensure the stability of the placement of the moving block 65.

[0031] When the present embodiment is used, during the use of the SMT material splicer, the material tape is placed on the conveyor belt 4, and after the material tape is transported to the bottom of the mounting frame 2 by the conveyor belt 4, the conveyor belt 4 is stopped, and the telescopic mechanism 1 is used to drive the two pressing frames 7 to move downward to perform a pressing operation on both ends of the material tape, and then the shearing mechanism 9 is used to shear the material tape, and then the film on the sheared material tape is removed, and the film is thrown to the side wall of the mounting frame 2, so that the recycling mechanism 5 can recover the film thrown to the side wall of the mounting frame 2. Subsequently, while the film inside the recycling mechanism 5 is discharged, the two support rods 672 are moved toward each other along the fixed column 675, and the two support rods 672 are moved. The connecting spring 673 is squeezed and connected. When the two support rods 672 are in contact with each other, the support rod 672 is stopped from moving. At this time, the moving block 65 loses the external supporting force, and the pushing rod 63 is then held by hand to drive the pushing plate 62 to move. The movement of the pushing rod 63 drives the moving block 65 to move inside the moving groove 66. Under the cooperation of the movement of the moving block 65 and the moving groove 66, the movement of the pushing rod 63 can be guided. The movement of the pushing plate 62 drives the brush 61 to move. During the movement of the brush 61, the film adhered to the components of the recycling mechanism 5 can be cleaned to prevent the film from adhering to the components of the recycling mechanism 5 and affecting the discharging operation of the film.
