The embodiments of the present invention are disclosed in the drawings, and, in the However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

1 and 2 are schematic views of the entire system of the embodiment of the present invention in different operational steps. The entire column system is used to form a stack of a plurality of stock materials 900 (in the following text, the stack of materials 900 is referred to as a stock pile 900'). The alignment system includes a platform 110, a gate 120, an adsorption device 130, and a dip device 140. The platform 110 has a stacking area 112 and a dip area 114. The stack of materials 900 (i.e., the stock pile 900') is placed on the stacking area 112 of the platform 110. The gate 120 is placed on the platform 110 and has an opening 122. The opening 122 is adjacent to the platform 110 and is located between the stacking zone 112 and the dip zone 114. The opening 122 has a height H, and each of the materials 900 has a thickness T which is equal to or greater than 1 times the thickness T and less than 2 times the thickness T. In some embodiments, the height H can be from 1 to 1.5 times the thickness T, and in other embodiments, the height H can be from about 1.1 to 1.2 times the thickness T. The platform 110 is placed between the material 900 and the adsorption device 130. The adsorption device 130 is configured to adsorb a portion of the material 900 through the platform 110 and pass the adsorbed material 900 through the opening 122 of the gate 120 to the dip region 114 such that the materials 900 passing through the opening 122 are not stacked with each other. . The picking device 140 is configured to respectively pick up the material 900 located in the picking area 114.

In operation, please refer to FIG. 3, which is a flowchart of the method of the entire column according to an embodiment of the present invention. First, the stack material 900 (i.e., the material pile 900') is placed on the stacking area 112 of the platform 110 as shown in step S11. The material 900 is, for example, a material for a micro electro mechanical system (MEMS) element, or a solder for a laminated structure of a light emitting diode. The collinear system and the collinear method of the present embodiment facilitate the arranging of the lightweight material 900, which cannot be oscillated by vibration, sway or directly by suction. However, in other embodiments, the material 900 is not limited to the above characteristics. In the present embodiment, the sheet material 900 is exemplified.

Next, as shown in step S13, the gate 120 is placed on the platform 110. The gate 120 can be, for example, a box shape that can be inverted upright on the platform 110 to cover the stock pile 900'. The opening 122 is disposed in the sidewall of the gate 120 such that when the gate 120 is inverted onto the platform 110, the opening 122 becomes the only passage for the material 900 to enter the dip zone 114 from the stacking zone 112. In other embodiments, the gate 120 may not be box-shaped. Basically, as long as the material 900 placed in the stacking zone 112 can only enter the dip zone 114 through the opening 122, it is within the scope of the present invention.

Next, as shown in step S15, a part of the material 900 is adsorbed through the stage 110, and in the present embodiment, the adsorption is performed by the adsorption device 130. The adsorption unit 130 primarily adsorbs a portion of the material 900 located at the bottom of the stock pile 900'. In particular, most of the material 900a of the contact platform 110 lies flat on the platform 110, so that the adsorption device 130 has a greater attractive force with the flat materials 900a. Conversely, other materials 900b stacked on the material 900a are less likely to be attracted by the adsorption device 130.

Next, as shown in steps S17 and 2, the adsorbed material 900 is driven through the opening 122 of the gate 120 to reach the dip region 114, so that the materials 900 passing through the opening 122 are not stacked with each other. In the mode, the adsorbed material 900 is driven by the adsorption device 130. Specifically, as described above, the height H of the opening 122 is equal to or greater than 1 times the thickness T of the material 900 and less than 2 times the thickness T, that is, only a single layer of material 900 can pass through the opening 122. The material 900 of the second layer or more is blocked by the opening 122 and cannot pass through the opening 122. That is, the material 900a located at the bottom of the material pile 900' and lying flat on the platform 110 can pass directly through the opening 122 by being carried by the adsorption device 130. On the other hand, only the other material 900b partially stacked on the material 900a may be adsorbed by the adsorption device 130, but when the opening 122 is reached, the material 900b is blocked by the opening 122 and is placed under the column. It is thus ensured that the materials 900 in the dip area 114 are not stacked with each other.

Next, as shown in step S19, the material 900 located in the dip area 114 is separately extracted. In the present embodiment, the material 900 is picked up by the dip device 140. Specifically, the dip device 140 can pick up each material 900 in a sucking or gripping manner and place it neatly on other carriers or substrates (not shown) to complete the alignment. Since the materials 900 in the dip area 114 are not stacked with each other, even if the dip device 140 picks up the material 900 in a sucking manner, more than two sheets of material 900 are not sucked at the same time, which helps to simplify the entire process.

Next, please refer to FIG. 2 and FIG. 4 together, wherein FIG. 4 is a top view of the dip area 114 of FIG. In the present embodiment, the alignment system may further include an image capture device 150 for capturing images of the material 900 located in the feed zone 114. Specifically, when the adsorption device 130 adsorbs the material 900 to After the dip zone 114, the direction in which the material 900 is placed is random, as shown in FIG. Therefore, before the picking device 140 performs the picking action, the image capturing device 150 can first capture the image of the feeding area 114 to obtain the position and the placing direction of each material 900 on the platform 110. Therefore, when the feeding device 140 performs the feeding operation, the feeding device 140 can be positioned to the capturing position according to the image, and the material 900 to be taken can be rotated to a predetermined orientation and then placed on the carrier or the substrate.

Please return to Figure 1. In the present embodiment, the material 900 may be a magnetic substance, and the adsorption device 130 is a magnetic force generating device. Therefore, even if the platform 110 is separated, the adsorption device 130 can adsorb the material 900. In some embodiments, the adsorption device 130 can be a magnet or an electromagnet. When the adsorption device 130 is a magnet, the magnetic strength of the adsorption material 900 can be changed by changing the distance between the adsorption device 130 and the material 900 (for example, a gasket having a different thickness is added between the platform 110 and the adsorption device 130) In order to obtain a more suitable adsorption force. When the adsorption device 130 is an electromagnet, the intensity of the adsorption force can be determined by adjusting the current intensity.

However, the adsorption device 130 is not limited to the magnetic force generating device. Please refer to FIG. 5, which is a schematic diagram of an entire system according to another embodiment of the present invention. In the present embodiment, the platform 110 has a plurality of through holes 116, and the adsorption device 130 is an air suction device. Therefore, the adsorption device 130 is configured to be placed at the bottom of the material pile 900' by pumping the through holes 116. 900 is adsorbed on the platform 110. Since the adsorption device 130 of the present embodiment adsorbs the material 900 by the difference in gas pressure, the material 900 is not necessarily a magnetic substance. Other details of the present embodiment are the same as those of Fig. 1, and therefore will not be described again.

Next, please refer to FIG. 6, which is a partial enlarged view of the shutter 120 and the platform 110 of FIG. In the present embodiment, the gate 120 may include a lifting device 124 for controlling the height H of the opening 122. For example, the shutter 120 can include a main body 126 and a movable plate body 128 for controlling the position of the movable plate body 128 relative to the main body 126 to form openings of different heights H between the main body 126 and the movable plate body 128. 122. Since different types of materials 900 (as shown in FIG. 1) have different thicknesses T, the height H of the openings 122 can be adjusted according to the thickness T of the material 900 (as shown in FIG. 1). Material 900. The lifting device 124 is, for example, a button, a rotating shaft or other suitable moving device, and the invention is not limited thereto. In addition, different gates 120 can be replaced to align different types of materials 900.

The above contents are all exemplified by the material 900 having no front and back surfaces, but the above-described arranging device can also be used to arrange the front and back fabric materials 900. For example, please refer to FIG. 7 , which is a schematic diagram of a material 900 according to an embodiment of the present invention. In the present embodiment, the material 900 has, for example, a cap 910 and a cap 920, that is, different front and back surfaces, so that the front and back surfaces of the material 900 need to be resolved together when the column is aligned. Referring to FIG. 8 and FIG. 9 together, FIG. 8 is a schematic diagram of the dip device 140 and the detection system 160 of the alignment system according to still another embodiment of the present invention, and FIG. 9 is an imaging screen 164 of FIG. Front view. The detection system 160 is used to detect the front and back of the captured material 900. For example, detection system 160 includes a light source 162 and an imaging screen 164. Light source 162 is used to illuminate the sides of material 900. Light source 162 projects image 902 of material 900 onto imaging screen 164. After step S19 of FIG. 3 (i.e., after the material 900 is picked up by the picking device 140), the light source 162 can illuminate the material 900. The material 900 is projected to the imaging screen 164 to form an image 902, wherein the image 142 of FIG. 9 is an image projected by the light source 142 onto the imaging screen 164 by the light source 162. Since the cap 910 of the material 900 and the cap 920 have different widths, the image 902 projected onto the imaging screen 164 also has a different width, so that the front and back of the material 900 can be judged by the image 902, and then Then, the feeding device 140 adjusts its front and back surfaces and then places it on the carrier or the substrate. However, the detection system 160 described above is merely illustrative and is not intended to limit the invention. A person skilled in the art to which the present invention pertains can flexibly select a method for detecting the front and back of the material 900, depending on the actual situation.

In summary, the collinear system and the collinear method of the embodiments of the present invention utilize the adsorption device to adsorb the material and pass through the opening, so that the materials in the mashing area are not stacked with each other, and then the picking device is separately taken from the mashing area. The material can solve the problem of the whole column of the light or flake material and also help to simplify the whole process.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
