detailed description

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.

As shown in Figure 1, a shutter shading device for an exposure machine of the present invention includes a frame 1, a lamp light box 2 is arranged inside the frame 1, and two groups of lights are arranged above the light box 2. The slidable first light blocking plate 3 and the second light blocking plate 4 are provided with a first guide rail 5 on the frame 1, and the first light blocking plate 3 and the second light blocking plate 4 pass through the slider and the second light blocking plate respectively The first guide rail 5 is connected, and the size of the first light-shielding plate 3 and the second light-shielding plate 4 matches the size of the working area of the lamp box 2, and the first cylinder 6 and the second cylinder are arranged on the frame 1 7. The first air cylinder 6 and the second air cylinder 7 are connected to the first light baffle 3 and the second light baffle 4 respectively, so that the first light baffle 3 and the second light baffle 4 are arranged in tandem, When in use, one of the first light-shielding plate 3 and the second light-shielding plate 4 driven by the first cylinder 6 and the second cylinder 7 will slide axially and reach the top of the light-emitting lamp box 2 for light-shielding work (assuming It is the first light-shielding plate 3), after the first light-shielding plate 3 has finished blocking light and the next PCB board is exposed, it is the turn of the second light-shielding plate 4 to block light, and work alternately in this way.

In a preferred embodiment, one side of the first light-shielding plate 3 and the second light-shielding plate 4 is folded downwards and extended to form a side dam 8, and the assembly directions of the first light-shielding plate 3 and the second light-shielding plate 4 are opposite to each other. On the contrary, the side baffles 8 are respectively placed above the front and rear ends of the light-emitting light box 2 of the light tube, and the position of the side baffle 8 is just above the edge of the light-emitting light box 2 of the light tube or outside the light-emitting light box 2 of the light tube. Above, specifically: the side block 8 is arranged above the edge of the light-emitting light box 2 of the light tube or above the outer side of the light-emitting light box 2 of the light tube, so that the light emitted by the light-emitting light box 2 of the light tube can only directly illuminate the first gear when it is working. light plate 3 or the second light baffle plate 4, then the light will be reflected by the first light baffle plate 3 or the second light baffle plate 4 to play the role of light blocking, but there will still be part of the light along the first light baffle plate 3 or the second light baffle plate The left and right directions of the light blocking plate 4 are diffused, and the setting of the side blocking portion 8 is to block the diffused light, so that the direction of the light is changed and returned to the lamp box 2, so that the first light blocking plate 3 and the second light blocking plate 4 The light blocking effect is better, avoiding the leakage of light and causing human safety hazards.

In a preferred embodiment, the first light-shielding plate 3 and the second light-shielding plate 4 are aluminum baffles, and the bottom end surfaces of the first light-shielding plate 3 and the second light-shielding plate 4 are provided with a heat-absorbing coating. Aluminum and heat-absorbing coating, so that the first light-shielding plate 3 and the second light-shielding plate 4 have a good heat-absorbing effect, and can assist the heat dissipation system of the exposure machine to play a certain role in heat dissipation for the light-emitting light box 2 of the light tube when blocking light As a result, through the mutual replacement of the first light-shielding plate 3 and the second light-shielding plate 4, when the first light-shielding plate 3 works to block light, the second light-shielding plate 4 resets and leaves the working area of the light-emitting lamp box 2 to dissipate heat. Under the premise that the first light-shielding plate 3 and the second light-shielding plate 4 themselves will not be deformed, they can effectively assist the heat dissipation of the light-emitting light box 2 of the lamp tube, and have strong practicability.
