Technical Field

[0001] The invention relates to an automation device, in particular to a backlight platform lifting device for a substrate. Background Art

[0002] Nowadays, copper foil or ceramic substrates used in the production of circuit boards are mostly inspected manually by taking the substrate and then inspecting it with instruments such as high-power microscopes or magnifying glasses, or by instruments such as copper thickness gauges to measure the thickness and other values. In particular, when the substrate needs to be turned over, although the existing equipment can be inspected by instruments, the turning of the substrate still requires manual work.

[0003] However, this is no longer sufficient for today’s automated production. On the one hand, most other processes have already adopted automated methods for production and related testing processes. If manual methods are needed in the middle of the process, it will not only waste manpower, but also reduce production efficiency; on the other hand, manual testing is more prone to human errors, and the reliability of the test results is not as good as that of mechanical equipment.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] See also Figure 1 , which is a plan view of the present invention. The present invention provides a backlight platform lifting device for a substrate, the lifting device 1 is used for placing a substrate 2, and can measure the thickness of the substrate 2 through a measuring tool (not shown), or can detect the surface of the substrate 2 through an image sensor (such as CCD). The lifting device 1 includes a base 10, at least one backlight module 11 disposed on the base 10, at least one light guide plate 12 disposed on the base 10 and located above the backlight module 11, and a driving platform 13 disposed below the backlight module 11; wherein: The base 10 is used to carry the above-mentioned components, and has a first supporting structure 100 and a second supporting structure 101 for fixing the above-mentioned backlight module 11 and the light guide plate 12. The first supporting structure 100 and the second supporting structure 101 can be arranged on the inner wall of the base 10 in a surrounding shape, and the first supporting structure 100 is located below the second supporting structure 101, so that the backlight module 11 is fixedly arranged on the first supporting structure 100 and is located below the light guide plate 12, or the light guide plate 12 is fixedly arranged on the second supporting structure 101 and is located above the backlight module 11. In addition, the above-mentioned driving platform 13 is arranged in the base 10 and is located below the backlight module 11.

[0026] like Figure 1 and Figure 2 As shown, the backlight module 11 can be arranged in multiple numbers on the horizontal plane of the first supporting structure 100 at intervals, so as to have multiple circuit boards 110 and multiple light-emitting elements 111 arranged on each circuit board 110; or only a single circuit board 110 can be arranged on the horizontal plane of the first supporting structure 100, so that multiple light-emitting elements 111 are arranged on the circuit board 110, and structures such as holes are arranged on the circuit board 110 as the aforementioned intervals. The light guide plate 12 is used for the substrate 2 to be placed flat thereon, and the light guide plate 12 can also be arranged in multiple numbers on the horizontal plane of the second supporting structure 101 at intervals; or only a single light guide plate 12 can be arranged on the horizontal plane of the second supporting structure 101, and a through hole 120 is arranged on the light guide plate 12 to correspond to the aforementioned intervals or holes of the backlight module 11. In addition, the light guide plate 12 can be frosted glass (or ground glass), or a frosted glass surface or a frosted surface can be formed on at least one side of the light guide plate 12 to be suitable for the inspection operation of the surface of the substrate 2 .

[0027] like Figures 1 to 3 As shown, the driving platform 13 includes a driver 130 and a plurality of lifting brackets 131 driven by the driver 130 to move up and down. Each of the lifting brackets 131 corresponds to each of the through holes 120 of the light guide plate 12, and can pass through the spacing or holes of the backlight module 11, so that when the driver 130 moves each of the lifting brackets 131 upward, the substrate 2 placed flat on the light guide plate 12 can be lifted upward. Further, each of the lifting brackets 131 can be jointly arranged on a horizontal carrier 132, and then the driver 130 drives the carrier 132 to move up and down, and then the carrier 132 can simultaneously drive each of the lifting brackets 131 to move up and down.

[0028] Therefore, by means of the above-mentioned structural composition, the backlight platform lifting device for the substrate of the present invention can be obtained.

[0029] Accordingly, when one of the surfaces of the substrate 2 has completed any of the aforementioned inspection operations and it is desired to perform inspection operations on the other surface. Figure 3 As shown, the driver 130 of the driving platform 13 drives each lifting bracket 131 to lift the substrate 2 upward, and then a clamping arm mechanism 3 can clamp the substrate 2 through the spacing between the lifting brackets 131, that is, Figure 4 and Figure 5 In this way, the substrate 2 can be turned over by the automated clamping arm mechanism 3, so that the other surface of the substrate 2 can be inspected easily.

[0030] like Figure 5 As shown, further, the clamping arm mechanism 3 may include a cantilever 30 and a clamp 31 pivotally mounted on the cantilever 30. The cantilever 30 is provided with a rotary motor 300, which may be a stepping motor and has a rotating shaft 301 to connect to the clamp 31. The clamp 31 includes a cross-carrying portion 310, and a first clamping arm 311 and a second clamping arm 312 disposed on the cross-carrying portion 310 and extending therefrom. The first clamping arm 311 has a first clamping end 311a and a first movable end 311b, and at least one movable rod 311c is provided on the first clamping end 311a for the first movable end 311b to be movably arranged. The first clamping arm 311 is further provided with a pusher 313, and the pusher 313 can be a pneumatic cylinder or a hydraulic cylinder, and is linked to the first movable end 311b by a push rod 313a; when the pusher 313 pushes the push rod 313a to move forward, the push rod 313a can be connected to the first movable end 311b by the crank 313b, so that the first movable end 311b can be moved on the movable rod 311c to move away from the first clamping end 311a, so as to clamp the substrate 2 toward the second clamping arm 312.

[0031] As mentioned above, the second clamping arm 312 may also have a second clamping end 312a and a second movable end 312b, and the second clamping end 312a and the second movable end 312b are connected by an elastic element 312c; thus, when the first movable end 311b clamps the substrate 2 toward the second clamping arm 312, the second clamping arm 312 can clamp the substrate 2 more tightly by the elastic setting between the second clamping end 312a and the second movable end 312b, and can effectively reduce the damage to the substrate 2 caused during the clamping process.

[0032] like Figure 6 and Figure 7As shown, after the clamping arm mechanism 3 is able to firmly clamp the substrate 2, the rotating motor 300 of the cantilever 30 can drive the clamp 31 to perform a 180° flip rotation. In the embodiment of the present invention, the clamp 31 may have two sets of first clamping arms 311 and a second clamping arm 312, which extend from two ends of the cross-carrying portion 310 respectively to form a "U" shape.

[0033] Finally, if Figure 8 As shown, the turned-over substrate 2 is placed on each of the lifting brackets 131 through the clamping arm mechanism 3, and the driver 130 drives the carrier 132 to lower the substrate 2 onto the light guide plate 12 so as to perform the above-mentioned inspection operation on the other side of the substrate 2.

[0034] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
