Technical Field

[0001] This invention relates to an impact condition confirmation device and a method for impact condition confirmation. Background Technology

[0002] In the manufacturing process of display devices (e.g., OLED-related), a uniform and precise printing process is required on the object. Simultaneously, to perform this printing, the object needs to be supplied in a stable and optimal state beforehand. That is, the object needs to be provided to the printing tool in a matched state to ensure accurate printing and precise measurement of the resulting impact. In the prior art, techniques based on encoders have been developed for supplying objects during the feeding process. However, this method suffers from difficulties in preventing object detachment, preventing slippage, verifying equipment status, and accurately controlling the amount of object movement.

[0008] The technical problems of this invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned through the following description.

[0009] An impact condition confirmation device according to one aspect of the present invention for solving the above-mentioned technical problems may include: a first supply unit for supplying an object by rolling; a second supply unit for receiving the object from the first supply unit by rolling and supplying the object to a demand location; a changing unit for applying pressure to the object to impart tension or releasing the pressure to release the tension based on a position change; a sensing unit for sensing the position change of the changing unit to generate position information of the object; a guiding unit disposed between the first supply unit and the second supply unit and guiding the object; and a control unit for controlling the processing technology including the supply of the object based on the position information of the sensing unit.

[0035] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention, as well as methods for achieving these advantages and features, will be explained by referring to the following description in conjunction with the accompanying drawings. Figure 1The invention becomes clear from the detailed description of the embodiments. However, the invention is not limited to the embodiments disclosed below, but can be implemented in many different forms. These embodiments are provided only to make the disclosure of the invention complete and to fully inform those skilled in the art of the scope of the invention, which is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same constituent elements.

[0036] To readily describe the relationship between one element or component and another, as shown in the figure, spatial relative terms such as "below," "below," "lower," "above," and "upper" can be used. It should be understood that, in addition to the orientation shown in the figure, spatial relative terms also include terms indicating the different orientations of the elements during use or operation. For example, when the element shown in the figure is flipped, an element described as "below" or "below" of another element may be located "above" of that element. Therefore, the exemplary term "below" can include both "below" and "above" orientations. Element may also be oriented in another direction, thus spatial relative terms can be interpreted according to orientation.

[0037] Although the terms "first," "second," etc., are used to describe various elements, constituent elements, and / or parts, these elements, constituent elements, and / or parts are obviously not limited by these terms. These terms are only used to distinguish one element, constituent element, and / or part from another element, constituent element, and / or part. Therefore, the first element, first constituent element, or first part mentioned below can obviously also be a second element, second constituent element, or second part within the technical concept of the present invention.

[0038] The terminology used in this specification is for illustrative purposes and is not intended to limit the invention. In this specification, the singular form includes the plural form unless specifically stated otherwise. The terms "comprises" and / or "comprising" as used in this specification do not exclude the presence or addition of one or more other constituent elements, steps, operations, and / or components in addition to those mentioned.

[0039] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in the sense that would be commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, terms defined in commonly used dictionaries are not to be ideally or excessively interpreted unless explicitly defined otherwise.

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. When describing the invention with reference to the drawings, identical or corresponding constituent elements are given the same reference numerals, regardless of the reference numerals, and repeated descriptions thereof are omitted.

[0041] Reference Figure 1 According to an embodiment of the present invention, the impact state confirmation device includes an input unit S, a first drive unit 105, a first supply unit 110, a second drive unit 115, a second supply unit 120, a change unit 130, a sensing unit 140, a guiding unit 150, a control unit 160, and an discharge unit E.

[0042] Here, the aforementioned sensing unit 140 includes a first sensing unit 141, a second sensing unit 142, and a third sensing unit 143 (see...). Figures 5-7 The aforementioned guiding unit 150 includes a first guiding unit 151, a second guiding unit 152, and a third guiding unit 153.

[0043] The object M is fed into the input section S. The first supply unit 110 transfers the object M backward by rolling. The object M is supplied in a rollable manner through the input section S.

[0044] Conversely, the aforementioned input section S can also be the part through which the aforementioned object M simply passes in the form of a roller, and the part that is actually configured to be rollable can be the aforementioned first supply unit 110.

[0045] The second supply unit 120 receives the object M from the first supply unit 110 by rolling. The second supply unit 120 then supplies the object M to the demand location. The first drive unit 105 and the second drive unit 115 provide driving force to the first supply unit 110 and the second supply unit 120 to enable rolling.

[0046] On the other hand, the aforementioned demand area includes a destination for processing the aforementioned object M. Meanwhile, the aforementioned discharge unit E corresponds to the location or area where object M is discharged to supply it to the demand area. The aforementioned second supply unit 120 is arranged on the same line as the aforementioned first supply unit 110, or at a different location than the first supply unit 110, such as at a different height.

[0047] Reference Figures 1 to 4 The aforementioned alteration unit 130 applies pressure to the object M based on a change in position. This pressure imparts tension to the object M, or releases the pressure to relieve the tension.

[0048] The aforementioned alteration unit 130 applies or releases the tension at least during the process of the object M passing through the first supply unit 110 and the second supply unit 120, thereby controlling the speed at which the object M is transferred.

[0049] Reference Figures 5 to 7 The sensing unit 140 senses the position change of the changing unit 130. The sensing unit 140 generates position information corresponding to the position change of the object M. At this time, the changing unit 130 changes to a first changing state to a third changing state.

[0050] The first change state is when the change unit 130 moves from the predetermined reference position L0 to a first position L1, which is the lower position. The second change state is when the change unit 130 moves from the reference position L0 to a second position L2, which is the upper position. The third change state is when the change unit 130 moves to a third position L3, which is the lower position of the first position L1.

[0051] The first sensing unit 141 of the sensing unit 140 senses the first change state of the changing unit 130 to generate first position information. The second sensing unit 142 of the sensing unit 140 senses the second change state of the changing unit 130 to generate second position information. The third sensing unit 143 of the sensing unit 140 senses the third change state of the changing unit 130 to generate third position information.

[0052] At the same time, the control unit 160 controls the processing steps, including the transfer of the aforementioned object, throughout the entire process. The control unit 160 interrupts the processing steps for the object M when the third position information is generated.

[0053] More specifically, the control unit 160 obtains first speed information of the change unit 130 from the first change state or the second change state to the third change state based on the first position information to the third position information, so as to execute the interruption of the processing process.

[0054] At the same time, when the first speed information does not meet the preset benchmark value, the processing is interrupted with a first delay value; when the first speed information meets the benchmark value, the processing is interrupted with a second delay value greater than the first delay value.

[0055] Here, the first delay value and the second delay value include the time for interrupting the process. Therefore, the second delay value is equivalent to a value used to interrupt the process by a longer delay than the first delay value.

[0056] Under normal circumstances, even if the aforementioned change unit 130 switches to the third change state, the aforementioned control unit 160 interrupts the aforementioned processing at a preset normal speed. However, the faster the aforementioned change unit 130 switches to the aforementioned third change state, the greater the pressure applied to the aforementioned object M.

[0057] With this in mind, when the first speed information meets the reference value, the processing is interrupted with a second delay value that has a greater delay than the first delay value.

[0058] Therefore, when the aforementioned changing unit 130 is changed to or below the aforementioned third position L3, i.e., when it falls, it can prevent the aforementioned object M from being damaged or detached due to friction and tension caused by a sudden interruption of the transfer.

[0059] The control unit 160 adjusts the supply speed of object M on the first supply unit 110 and the second supply unit 120 based on the change unit 130 changing from the first change state to the second change state.

[0060] Here, the control unit 160 obtains second speed information of the change unit 130 from the first change state to the second change state based on the first position information and the second position information, so as to adjust the supply speed of the object M.

[0061] For example, when the second speed information does not meet the preset second reference, the control unit 160 supplies the object M with a first speed value that is a preset arbitrary normal speed.

[0062] Simultaneously, when the second speed information meets the second reference, the control unit 160 supplies the object M with a second speed value greater than the first speed value. Here, the second speed value is equivalent to a speed value set to be faster than the first speed value.

[0063] The first guide unit 151 of the aforementioned guide unit 150 is a bar-shaped body located on the side of the first supply unit 110 and guides the supply of the object M. The second guide unit 152 is a bar-shaped body located on the side of the second supply unit 120 and guides the supply of the object M.

[0064] The third guide unit 153, as a rod-shaped body, is located between the first guide unit 151 and the second guide unit 152, and guides the supply of the object M.

[0065] On the other hand, the aforementioned alteration unit 130 is disposed adjacent to the aforementioned second guide unit 152 and is located above the object M guided by the aforementioned second guide unit 152, so as to impart tension or release tension according to the aforementioned pressure. For example, such an alteration unit 130 has a counterweight cone shape that imparts load and includes various shapes of structures that can realize vertical movement.

[0066] Reference Figure 8 and Figure 9 The aforementioned requirement is met by providing an impact tool 170 for impacting the liquid I on the aforementioned object M. The impact tool 170 includes a placement panel 171, a spraying unit 172, and a shooting unit 173.

[0067] The object M is placed on the placement panel 171 of the impact tool 170. The placement panel 171 has multiple through holes TH for adsorbing the object M. The injection unit 172 injects the liquid I onto the placed object M to generate an impact.

[0068] The aforementioned imaging unit 173 captures images of the aforementioned spraying unit 172 and the aforementioned liquid I. This imaging unit 173 measures the size and uniformity of the liquid I impacting the placed object M. Simultaneously, it can also capture images of the liquid I during the discharge process to measure its state.

[0069] Reference Figure 10 According to an embodiment of the impact state confirmation method (S100) of the present invention, firstly, in S110, an object M is introduced to supply the object M to the demand location. In step S120, the object M is passed through a first supply unit 110 and a second supply unit 120. In step S130, the object M that has passed through the first supply unit 110 and the second supply unit 120 is discharged to the demand location.

[0070] Here, the object M is guided by the guiding unit 150 and tensioned or relaxed based on the position change of the changing unit 130. The sensing unit 140 senses the position change of the changing unit 130 to generate position information. The control unit 160 controls the process on the object M based on the position information.

[0071] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art should understand that the present invention can be implemented in other specific forms without changing its technical concept or essential features. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
