Description

Technical Field

[0001] This utility model relates to a process equipment, and more particularly to a liquid cup holding unit and a liquid receiving device. Background Technology

[0002] The liquid cup receiving unit is typically located on the liquid receiving device for cleaning residual liquid from the liquid valve nozzle and measuring the amount of liquid dispensed by the valve. For example, in semiconductor manufacturing, liquid is dripped, coated, or applied to the holes or surfaces of the workpiece using the liquid valve of a liquid coating apparatus. After a period of use, liquid residue may remain on the liquid valve nozzle due to the viscosity of the liquid, necessitating cleaning of the nozzle.

[0003] After use, the liquid cup in the liquid container unit must be removed and cleaned before continued use. However, sometimes users forget to put the liquid cup back into the liquid container unit after removing it. If nozzle cleaning or liquid measurement is performed directly on the liquid container unit without the liquid cup in place, the liquid will splash into the liquid container unit, causing contamination inside. Utility Model Content

[0004] Therefore, one object of this utility model is to provide a liquid cup holding unit and liquid receiving device that can overcome at least one disadvantage of the prior art.

[0005] In accordance with the aforementioned objective disclosed in this utility model, a liquid cup containing unit is proposed, comprising a body and a detection element. The body has a chamber and a through hole. The chamber is configured to contain a liquid cup. The through hole communicates with the chamber. The detection element is disposed on the side of the liquid cup and configured to detect the presence of the liquid cup in the chamber.

[0006] In accordance with the aforementioned objectives disclosed in this utility model, a liquid receiving device is further proposed, comprising a base and a fixing frame. The fixing frame includes a support component and a fixing seat. The support component is disposed on the base. The fixing seat is supported by the support component and maintains a distance from the base, and the fixing seat has a hollowed-out section for the main body to pass through.

[0007] According to the above embodiments, the detection element of the liquid cup holding unit disclosed in this utility model can detect whether a liquid cup is present in the liquid cup holding unit. This prevents users from performing liquid handling operations on the liquid cup holding unit without inserting a liquid cup, and prevents liquid from splashing outside the liquid cup and contaminating the device.

[0060] The embodiments of this utility model are discussed in detail below. However, it is understood that the embodiments provide many applicable concepts that can be implemented in a wide variety of specific situations. The discussed and disclosed embodiments are for illustrative purposes only and are not intended to limit the scope of this application. All embodiments of this utility model disclose a variety of different features, but these features can be implemented individually or in combination as needed.

[0061] Furthermore, the terms "first," "second," etc., used in this article do not specifically refer to order or sequence; they are merely used to distinguish elements or operations described using the same technical terms.

[0062] The spatial relationship between the two elements described in this utility model applies not only to the orientation shown in the drawings, but also to orientations not shown in the drawings, such as inverted orientations. Furthermore, the terms "connection," "electrical connection," or similar expressions used in this utility model to refer to the two components are not limited to a direct or electrical connection, but may also include indirect or electrical connections as needed.

[0063] Please refer to Figure 1 and Figure 2 These are perspective and side views illustrating a liquid receiving device 200 according to one embodiment of the present invention. The liquid receiving device 200 is suitable for carrying one or more liquid cup receiving units 100 and 100a. The liquid receiving device 200 mainly includes a base 210 and a fixing frame 220.

[0064] The base 210 allows the mounting bracket 220 to be mounted thereon. For example, the base 210 may be a plate-like structure or a support structure, etc., on which the mounting bracket 220 can be mounted. In some embodiments, such as... Figure 1 As shown, the mounting bracket 220 includes a support assembly 222 and a mounting base 224. The support assembly 222 may be a bracket structure and is mounted on the base 210. The mounting base 224 may be a plate-like structure. The mounting base 224 is mounted on the support assembly 222 and is supported by the support assembly 222, maintaining a certain distance from the base 210. The mounting base 224 may have one or more open sections 226 for one or more liquid cup receiving units 100 and 110a to pass through.

[0065] Please refer to Figures 3 to 5 , Figure 3 and Figure 4 These are perspective and exploded views of a liquid cup containing unit 100 according to one embodiment of the present invention. Figure 5 This is a cross-sectional schematic diagram illustrating a liquid receiving device 200 according to one embodiment of the present invention. In some embodiments, the liquid cup receiving unit 100 is adapted to allow a liquid valve nozzle to perform a cleaning operation thereon to remove residual liquid from the liquid valve nozzle. The liquid cup receiving unit 100 may mainly include a body 300 and a detection element 400.

[0066] like Figure 4 and Figure 5 As shown, the body 300 is primarily used to contain the liquid cup 110. The body 300 has interconnected chambers 310 and through holes 320. The chambers 310 contain the liquid cup 110. The through holes 320 allow liquid to flow into the chambers 310. For example, the body 300 may be a cylindrical or box-shaped structure with an internal chamber 310. In some embodiments, the body 300 includes a cylindrical body 330 and a cover 340. Figure 4 As shown, the cylinder 330 has an opening 332, and the chamber 310 is located in the cylinder 330. The chamber 310 and the opening 332 are connected to each other, so the liquid cup 110 can enter and exit the chamber 310 through the opening 332 and be placed in the body 300.

[0067] like Figure 3 and Figure 4 As shown, the cover 340 is disposed on the cylinder 330 and can selectively cover the opening 332. Specifically, depending on the operational requirements, the cover 340 may or may not cover the opening 332. When the cover 340 does not cover the opening 332, the liquid cup 110 can enter and exit the chamber 310 through the opening 332, that is, the user can take out the liquid cup 110 or place it into the chamber 310 through the opening 332.

[0068] In some embodiments, a through-hole 320 is provided in the cover 340 and extends through the cover 340 to communicate with the chamber 310. This allows liquid to flow into the chamber 310 via the through-hole 320. Figure 3 and Figure 5As shown, in some embodiments, the liquid cup receiving unit 100 further includes a liquid guide tube 500. The liquid guide tube 500 can pass through the through hole 320. The liquid guide tube 500 has a liquid channel 510, a liquid inlet 520, and a liquid outlet 530. The liquid channel 510 can pass through the liquid guide tube 500 from top to bottom, and the liquid inlet 520 and the liquid outlet 530 are respectively located at opposite ends of the liquid channel 510. For example, the liquid inlet 520 is located outside the chamber 310, while the liquid outlet 530 is located inside the chamber 310. The liquid outlet 530 can also extend into the liquid cup 110. In this way, when the liquid cup receiving unit 100 performs liquid valve nozzle cleaning operations, the liquid can flow directly into the liquid cup 110 through the liquid outlet 530. Therefore, it can prevent liquid from splashing outside the liquid cup 110, or reduce the amount or range of liquid splashed outside the liquid cup 110, making it easier to clean the liquid cup holding unit 100 afterwards.

[0069] In some embodiments, such as Figure 5 As shown, the main body 300 further includes a sealing ring 350. The sealing ring 350 is disposed between the cylinder 330 and the cover 340. Specifically, the sealing ring 350 can be fitted onto the outer periphery of the bottom of the cover 340. When the cover 340 is installed on the cylinder 330, the sealing ring 350 can be sandwiched between the cover 340 and the cylinder 330 to fill the gap between them, so as to avoid air leakage during the vacuuming operation of cleaning the liquid valve nozzle and reduce the vacuuming effect of the liquid cup holding unit 100.

[0070] In some embodiments, such as Figure 3 As shown, the detection element 400 is disposed on the side of the liquid cup 110 and configured to detect the presence of the liquid cup 110 in the chamber 310 of the body 300. In some embodiments, such as Figure 5 As shown, the detector 400 is disposed on the body 300, and the height range of the detector 400 is compatible with the height range of the liquid cup 110 placed within the container 310. Specifically, the horizontal plane of the detector 400's suspended position can pass through the liquid cup 110, so that the detector 400 can effectively measure the liquid cup 110 within the container 310. The detector 400 can be substantially horizontal. However, in some specific embodiments, the detector 400 is not horizontal. The detector 400 can be disposed at any position within the body 300 that can detect the presence or absence of the liquid cup 110 to be contained in the container 310; this application is not limited to this.

[0071] By installing the detector 400, even when the cover 340 covers the opening 332, preventing the user from directly viewing the container 310, the user can still detect whether the liquid cup 110 has been placed in the container 310. In this way, the user can avoid performing liquid-related processing operations on the liquid cup holding unit 100 when the liquid cup 110 is not properly placed in the container 310.

[0072] In some embodiments, the detector 400 is a contrast-type optical detector, a reflective optical detector, or a capacitive detector. Specifically, in an embodiment where the detector 400 is a contrast-type optical detector, the detector 400 on the body 300 has a transmitter and a receiver separately disposed on both sides and facing each other. When an object is between the transmitter and the receiver and blocks the light emitted by the transmitter, the receiver will detect the interruption of light and generate a detection signal indicating the presence of an object. If the object is not between the transmitter and the receiver, the receiver can receive the light emitted by the transmitter and generate a detection signal indicating that the object is not present. The detector 400 can determine whether the liquid cup 110 is present in the container 310 by detecting the signal.

[0073] In embodiments where the detector 400 is a reflective optical detector, the detector 400 has a transmitter and a receiver disposed on the same side. When an object is present and blocks the light emitted by the transmitter, the receiver can receive the light reflected back from the surface of the object. If the object is not present, the receiver can receive the light reflected back from the inner surface of the body 300 on the other side. By observing the difference in the reflected light received by the receiver, it can be determined whether an object is present in the chamber 310. In other embodiments, the reflective optical detector has the characteristic of only receiving signals at a specific angle, thereby determining whether the liquid cup 110 is placed in the chamber 310. In embodiments where the detector 400 is a capacitive detector, the detector 400 can determine whether the liquid cup 110 is present in the chamber 310 by observing the change in capacitance value inside the chamber 310.

[0074] exist Figure 5 In some embodiments, the liquid cup receiving unit 100 includes a base 600. The base 600 is disposed in the receiving chamber 310 for the liquid cup 110 to be stably placed on it. In some embodiments, the base 600 includes a first component 610 and a second component 620. The first component 610 may be a circular or arbitrary shaped platform structure, and may be fixed to the body 300 by locking or adhesive methods, which are not limited thereto. The second component 620 is disposed on the first component 610 and may be a tray-like structure to facilitate the stable placement of the liquid cup 110 on it.

[0075] In some embodiments, such as Figure 4 and Figure 5 As shown, the liquid cup containing unit 100 includes an air nozzle 700. The air nozzle 700 can be located at the lower edge of the main body 300, and its two ends are respectively connected to the chamber 310 and the negative pressure air source. The negative pressure air source can evacuate the chamber 310 through the air nozzle 700, so that the chamber 310 is in a vacuum state, thereby drawing the residual liquid material of the liquid valve nozzle into the liquid cup 110 through the liquid guide tube 500, thus achieving the function of cleaning the liquid valve nozzle.

[0076] Please refer to the following at the same time Figure 2 and Figure 5 In some embodiments, the body 300 further includes a stop 360. The stop 360 is disposed on the outer edge of the body 300 and located below the detector 400. The stop 360 can support the body 300 passing through the hollow section 226. Specifically, the stop 360 is larger than the hollow section 226. When the liquid cup receiving unit 100 is disposed in the hollow section 226 of the fixing base 224, the bottom surface of the stop 360 will abut against the fixing base 224 and support the body 300, so that the body 300 is suspended after passing through the hollow section 226 and maintains a certain distance from the base 210. In some embodiments, the detector 400 of the liquid cup receiving unit 100 is located above the fixing base 224, and the air nozzle 700 is located below the fixing base 224 and between the base 210 and the fixing base 224.

[0077] Please refer to Figures 6 to 8 , Figure 6 and Figure 7 These are perspective and exploded views of a liquid cup containing unit 100a according to another embodiment of the present invention. Figure 8 This is a cross-sectional schematic diagram illustrating a liquid receiving device 200 according to another embodiment of the present invention. The liquid cup receiving unit 100a is used for measuring the amount of liquid discharged from the liquid valve. Similarly, the liquid cup receiving unit 100a mainly includes a body 300a and a detection element 400a.

[0078] like Figure 6 and Figure 7 As shown, the main body 300a also has a chamber 310a and a through hole 320a that are interconnected. The chamber 310a can accommodate the liquid cup 110a, and the liquid can flow into the chamber 310a through the through hole 320a. The main body 300a also includes a cylindrical body 330a and a cover 340a. The cylindrical body 330a has a chamber 310a and an opening 332a, wherein the chamber 310a is located in the cylindrical body 330a and communicates with the opening 332a, so the liquid cup 110a can enter and exit the chamber 310a through the opening 332a. The cover 340a is provided on the cylindrical body 330a and can selectively cover the opening 332a. The through hole 320a is provided in the cover 340a, thereby allowing the liquid to flow through the through hole 320a into the chamber 310a.

[0079] In some embodiments, such as Figure 8As shown, the biggest difference between the liquid cup receiving unit 100a and the liquid cup receiving unit 100 is that the bottom of the body 300a has a cutout 370, and the cutout 370 communicates with the chamber 310a. The cutout 370 is configured to allow external components to be placed below the liquid cup receiving unit 100a and enter the chamber 310a through the cutout 370. In some embodiments, the cutout 370 is smaller than the opening 332a. When an external device is placed below the liquid cup receiving unit 100a, the bottom surface of the body 300a can rest stably on the external device.

[0080] For example, such as Figure 8 As shown, the liquid receiving device 200 further includes a weighing scale 230, which is an example of the aforementioned external device. The weighing scale 230 is mounted on the base 210 and is located between the fixing base 224 and the base 210. The weighing scale 230 can support the liquid cup receiving unit 100a and can engage with the main body 300a to measure the weight of the liquid cup 110a. The weighing scale 230 includes a weighing part 232 located at the top of the weighing scale 230. The weighing part 232 can be a platform-like structure for placing the liquid cup 110a. Specifically, when the main body 300a is placed on the weighing scale 230, the weighing part 232 can pass through the perforation 370 into the receiving chamber 310a. At this time, the liquid cup 110a is placed on the weighing part 232, thereby allowing the weighing scale 230 to measure the weight of the liquid cup 110a.

[0081] In some embodiments, such as Figure 6 and Figure 7 As shown, the detection element 400a is also disposed on the main body 300a and configured to detect the presence of the liquid cup 110a in the container 310a. The detection element 400a can be substantially horizontally disposed. Specifically, the horizontal plane at which the detection element 400a is disposed can pass through the liquid cup 110a, so that the detection element 400a can effectively detect the liquid cup 110a in the container 310a. Similarly, the detection element 400a can be disposed at any position on the main body 300a that can detect the presence of the liquid cup 110a contained in the container 310a; this application is not limited to this. The detection element 400a can be, for example, a contrast optical detector, a reflective optical detector, or a capacitive detector.

[0082] Please refer to the following at the same time Figure 2 and Figure 8 The position of the detector 400a corresponds to the position where the liquid cup 110a can be detected, and the scale 230, which is connected to the liquid cup holding unit 100a, is located between the base 210 and the fixed base 224. Therefore, the detector 400a is located between the base 210 and the fixed base 224. Since the scale 230 supports the liquid cup 110a through the weighing part 232, the detector 400a is located between the weighing part 232 and the fixed base 224.

[0083] Detectors 400 and 400a may not be mounted on the main bodies 300 and 300a. Please refer to... Figure 9 This is a cross-sectional schematic diagram illustrating a liquid receiving device 200 according to another embodiment of the present utility model. Figure 9 The structure of the liquid cup containing unit 100b shown is roughly the same as... Figure 5 The liquid cup containing unit 100 shown is the same, the main difference being the different positions of the detection element 400. Figure 9 In this embodiment, the detector 400 is disposed within the chamber 310. For example, the detector 400 is located in the chamber 310 and is positioned on the side of the second component 620 corresponding to the liquid cup 110. If there is sufficient space in the chamber 310, a support member may also be provided in the chamber 310 for mounting the detector 400; this application is not limited to this.

[0084] Please refer to Figure 10 This is a cross-sectional schematic diagram illustrating a liquid receiving device 200 according to another embodiment of the present invention. Figure 10 The structure of the liquid cup containing unit 100c shown is roughly the same as... Figure 8 The liquid cup containing unit 100a shown is the same, the main difference being the position of the sensing element 400a. For example... Figure 10 As shown, the detector 400a is disposed within the chamber 310a and can detect the position of the liquid cup 110. In this embodiment, the body 300a also includes one or more retaining members 380 to retain the detector 400a. The retaining members 380 may be disposed within the chamber 310a and located around the position where the liquid cup 110 is located, so as to facilitate the detector 400a in detecting the liquid cup 110.

[0085] As can be seen from the above embodiments, the advantage of this utility model is that it has a detection element that can detect whether the liquid cup is present in the liquid cup holding unit. This prevents users from performing liquid handling operations on the liquid cup holding unit and liquid receiving device without inserting the liquid cup, thus avoiding liquid splashing outside the liquid cup and contaminating the device.

[0086] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present application. Anyone with ordinary knowledge in this art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
