The differences are as follows: In the embodiment of the present invention, the control button 7 is a button indicator light, and a sensor for detecting whether the light-shielding rubber strip 6 is inserted is arranged on one side of the L-shaped die hole close to the supporting die 4; when the light-shielding rubber strips 6 are inserted into all four L-shaped die holes, the control button 7 lights up.

[0030] Embodiment 4 See Figure 9, Embodiment 4 provides a processing tool for a light-shielding rubber strip, whose structure is basically the same as that of Embodiment 1, except that: in the embodiment of the present invention, the vertical plate 32 is located on the side of the strip-shaped hole away from the notch punching device 1, and the trimming cylinder 34 is located on the side of the vertical plate 32 close to the notch punching device 1.

[0031] Embodiment 5 Embodiment 5 provides a processing tool for a light-shielding rubber strip, whose structure is basically the same as that of Embodiment 1, except that: in the embodiment of the present invention, the lower die holder 12 and the mounting base 51 are connected together to form an integral structure.

[0032] Embodiment 6 Embodiment 6 provides a processing method for a light-shielding rubber strip, using the processing tool for a light-shielding rubber strip disclosed in Embodiment 1, 2, 3, 4 or 5. The method includes: two operators stand in front of and behind the workbench respectively and place two light-shielding rubber strips 6 at the front and rear of the processing tool respectively. The middle part of the light-shielding rubber strip 6 is placed on the L-shaped support surface and is located below the upper die 14. It is placed in the first L-shaped groove 42 of the support die 4, and its left and right ends are respectively inserted into the corresponding L-shaped die holes of the two trimming devices 3 and push out the previous trimming waste. The two operators operate the fixture 5 to clamp the two light-shielding rubber strips 6 on the front and rear sides of the lower die 13 respectively. After the control button 7 is lit, one of the operators presses the control button 7, and the notch punching device 1 and the two trimming devices 3 are synchronously driven to simultaneously perform trimming and punching. The punching process of the notch punching device 1 is as follows: the trimming cylinder 34 extends, and the lower die 13 moves downward to press against the horizontal edge of the light-shielding rubber strip 6; the upper die holder 11 continues to move downward, and the punching die 15 penetrates downward through the lower die 13, and its front and rear sides punch the corresponding light-shielding rubber strip 6 and its bottom abuts against the elastic buffer block 17. The trimming process of the trimming device 3 is as follows: the trimming cylinder 34 extends, and the cutting knife moves upward to perform trimming.
