Technical Field

[0002] Automated material handling systems (AMHS), also known as overhead crane systems, are widely used in semiconductor fabs.

[0030] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.
[0032] See attached Figure 1 As shown, a crane track in this embodiment includes two parallel track bodies 600. The wheel body of the crane 100 includes running wheels 200 and guide wheels 300. The two rows of running wheels 200 are respectively arranged on the upper side surfaces of the two track bodies 600, and the two rows of guide wheels 300 of the crane 100 are arranged on the inner side surfaces of the two track bodies 600. The crane 100 can travel along the extension direction of the track bodies 600 via the running wheels 200 and the guide wheels 300. In the following text, the outer side refers to the side opposite to the left and right rows of running wheels 200, and the inner side refers to the side opposite to the left and right rows of running wheels 200. The outer side is the side facing outward, and the inner side is the side facing inward.
[0033] When the traveling wheels 200 of the overhead crane 100 move along the track body 600, the traveling wheels 200, the guide wheels 300 and the track body 600 rub against each other to generate particles. These particles will be scattered with the airflow to the area of the process machine below the track during the movement of the overhead crane 100. After entering the process machine, the particles will contaminate and affect the quality of the substrate.
[0034] In the prior art, an upwardly extending baffle 400 is provided on the outer side of the track body 600, and an inwardly extending connecting plate 500 is provided on the inner side of the track body 600. These baffles 400 and connecting plates 500 block particles, preventing them from scattering into the process equipment area. However, while the baffles 400 and connecting plates 500 block most particles generated by friction between the running wheels 200 and guide wheels 300 and the track, these blocked particles still fall onto the track surface and the connecting plate 500 surface. When the overhead crane 100 is in motion, these fallen particles are disturbed by airflow and can still drift into the factory below the track, affecting factory cleanliness.
[0035] In the present application, a collection device 700 is provided, with at least a portion of the collection device 700 disposed within the track body 600, to collect particles generated by friction between the running wheels 200 and guide wheels 300 of the overhead crane 100 and the track body 600. Since the collection device 700 is disposed within the track body 600, the impact of airflow on particles within the collection device 700 during the travel of the overhead crane 100 is reduced, preventing particles from drifting back to the process equipment area below the track, contaminating and affecting the quality of the substrates. Furthermore, by disposing a portion of the collection device 700 within the track body 600, the space outside the overhead crane track occupied by the collection device 700 is reduced, thereby reducing the space occupied by the overhead crane track.
[0036] In some embodiments, the collection device 700 includes an adsorption mechanism disposed within the track body 600 and connected to a negative pressure mechanism. The negative pressure mechanism creates a negative pressure within the adsorption mechanism, thereby collecting and absorbing particles. Compared to prior art methods that use baffles or connecting plates to block particles, the present invention utilizes an adsorption mechanism to collect particles. Particles trapped within the track body 600 are less likely to be dispersed, resulting in improved particle collection.
[0037] See attached Figure 2 and attached Figure 3 As shown, in some embodiments, the collecting mechanism includes a collecting hole 1 provided on the track body 600 and along the length direction of the track body 600. The collecting hole 1 is connected to the side of the track body 600. And the collecting hole 1 is connected to the negative pressure mechanism outside the track body 600. Under the action of the negative pressure mechanism, the inside of the collecting hole 1 is negative pressure. Since the collecting hole 1 is connected to the side of the track body 600, a micro-negative pressure will be formed on the side of the track body 600, and the particles on the side of the track body 600 will be adsorbed into the collecting hole 1. Since the inside of the collecting hole 1 is in a negative pressure state, the particles adsorbed into the collecting hole 1 will not be dispersed again due to the airflow generated by the travel of the overhead crane 100. Compared with the prior art, the particles are blocked by setting the connecting plate 500 and the baffle 400, and the collection effect is better by setting the collecting hole 1 inside the track body 600 to adsorb and collect the particles.
[0038] In some embodiments, the sides of the collection hole 1 that connect to the track body 600 are the upper and inner sides that rub against the wheels of the overhead crane 100. The wheels include running wheels 200 that rub against the upper sides and guide wheels 300 that rub against the inner sides. Because particles are generated by the side friction between the wheels of the overhead crane 100 and the track body 600, the density of particles accumulated on the upper and inner sides of the track body 600 where the wheels of the overhead crane 100 travel is higher. By connecting the collection hole 1 to the upper and inner sides of the track body 600, the collection hole 1 is more effective in collecting particles.
[0039] In some embodiments, there are multiple collecting holes 1, and the multiple collecting holes 1 are arranged in parallel along the length direction of the track body 600, and the multiple collecting holes 1 are connected through the connecting holes 2. Figure 3As shown, the plurality of collecting holes 1 include a second collecting hole 12, a first collecting hole 11 disposed above the second collecting hole 12, and a third collecting hole 13 disposed inside the second collecting hole 12. The first collecting hole 11 and the second collecting hole 12 are connected via the connecting hole 2. By providing the connecting hole 2 between the first collecting hole 11 and the second collecting hole 12, a connecting wall is formed between the first connecting hole 2 and the second connecting hole 2. A connecting wall of a certain thickness is formed between the first collecting hole 11 and the second collecting hole 12, thereby improving the bending strength of the track body 600 in the vertical direction. This bending strength can reduce bending deformation of the track body 600 in the inward and outward directions, thereby improving the strength of the track body 600 in the inward and outward directions.
[0040] The third collecting hole 13 and the second collecting hole 12 are also connected through the connecting hole 2. By setting the connecting hole 2 between the third collecting hole 13 and the second collecting hole 12, a connecting wall is provided between the second connecting hole 12 and the third connecting hole 13, and the thickness of the connecting wall between the third collecting hole 13 and the second collecting hole 12 is retained, thereby improving the bending strength of the track body 600 in the inward and outward directions. This bending strength can reduce the bending deformation of the track section between the two hooks in the up and down directions, thereby improving the strength of the track body 600 in the up and down directions.
[0041] The first, second, and third collection holes 11, 12, and 13 can be replaced by a single hole formed from a single die. This means there are no connecting arms between the first, second, and third collection holes 11, 12, and 13. Instead, the first, second, and third collection holes 11, 12, and 13 form a single hole. In this case, the bending strength of the track body 600 is relatively weak and prone to deformation. This application improves the strength of the track body 600 by providing a connecting hole 2 that connects the first, second, and third collection holes 11, 12, and 13.
[0042] In this embodiment, three collecting holes 1 are set as an example (a first collecting hole 11, a second collecting hole 12 and a third collecting hole 13). In actual application, the number of collecting holes 1 can also be 2, 4, 5, etc., which can be adjusted according to actual conditions and is not limited in this application.
[0043] In some embodiments, the collection hole 1 is disposed inside the track body 600, and the adsorption hole 3 is disposed on the side of the track body 600. The collection hole 1 is connected to the side of the track body 600 through the adsorption hole 3. The adsorption hole 3 has a smaller diameter than the collection hole 1, so that the adsorption hole 3 has a greater adsorption force on the particles on the side of the track body 600, thereby better adsorbing the particles.
[0044] In some embodiments, the collection holes 1 are elongated holes extending along the length of the track body 600 and are produced using a film-drawing process. The adsorption holes 3 are also elongated holes extending along the length of the track body 600 and are produced using a film-drawing process. By extending the adsorption holes 3 along the length of the track body 600, the adsorption area of the adsorption holes 3 for adsorbing particles can be increased.
[0045] In other embodiments, the adsorption holes 3 are multiple small holes spaced apart along the length of the track body 600. The small holes are drilled circular holes or milled long holes. By providing the adsorption holes 3 as multiple small holes spaced apart, the adsorption strength of the adsorption holes 3 on particles can be improved.
[0046] In some embodiments, the adsorption holes 3 include a first adsorption hole 31 and a second adsorption hole 32. The first adsorption hole 31 is located on the upper side of the track body 600 and is connected to the first collecting hole 11. It is mainly used to adsorb and collect particles generated by friction between the upper side of the track body 600 and the running wheel 200. The second adsorption hole 32 is set on the inner side of the track body 600 and is connected to the third collecting hole 13. The second adsorption hole 32 mainly collects particles on the connecting plate 500. Specifically, an opening is provided on the connecting plate 500, and the opening is connected to the second adsorption hole 32. The negative pressure in the third collecting hole 13 adsorbs the particles on the connecting plate 500 and the particles floating above the connecting plate 500 through the second adsorption hole 32 and the openings on the connecting plate 500, and adsorbs the particles into the third collecting hole 13. The openings on the connecting plate 500 are arranged at intervals along the length of the track. The wall thickness between adjacent openings can prevent the connecting plate 500 from breaking and increase the strength of the connecting plate 500.
[0047] The first adsorption holes 31 and the second adsorption holes 32 are connected via the first collection hole 11, the connection hole 2, the second collection hole 12, another connection hole 2, and the third collection hole 13. When it is necessary to collect particles from the track body 600 and the connection plate 500, negative pressure is applied to the first collection holes 11, the second collection holes 12, and the third collection holes 13. The adsorption holes 3 generate suction on the air outside the track body 600, and the particles are drawn into the connection hole 2 along with the airflow. They are then transported out to the outer side of the track body 600 through the first collection holes 11, the second collection holes 12, and the third collection holes 13.
[0048] Specifically, an interface 5 is provided at the end of the track body 600. Interface 5 includes a first interface 51, which is connected to the first collection hole 11, the second collection hole 12, and the third collection hole 13. A negative pressure mechanism is provided at the first interface 51 to suck gas from the collection hole 1, creating a negative pressure within the collection hole 1. The first collection hole 11, the second collection hole 12, and the third collection hole 13 can be connected to the first interface 51 separately, or they can be combined first and then connected to the first interface 51. The negative pressure mechanism can be a suction fan or a negative pressure pump, and the choice can be made based on the specific situation.
[0049] There are multiple first interfaces 51 , and a negative pressure mechanism can be provided at each first interface 51 . Alternatively, some first interfaces 51 can be blocked, and other first interfaces 51 can be connected to the negative pressure mechanism, depending on the actual situation.
[0050] In some embodiments, the collection device 700 further includes an air supply mechanism, which is disposed inside the track body 600 and can deliver static-eliminating gas to the side of the track body 600. The gas escapes through the air supply mechanism and contacts the running wheel 200, which can eliminate static electricity on the running wheel 200. The particles on the running wheel 200 are then easily detached from the running wheel 200 and can be adsorbed and collected by the adsorption mechanism. Therefore, the present application eliminates static electricity on the running wheel through the provision of the air supply mechanism and the adsorption mechanism, making it easier to separate the particles from the wheel body, and then performs adsorption collection through the adsorption mechanism, thereby improving the collection effect of the collection device on the adsorption of particles.
[0051] The air supply mechanism includes a first hole 4, which is arranged along the length of the track body 600. The first hole 4 is connected to the side of the track body 600 and is not connected to the collection hole 1. The first hole 4 is connected to the side of the track body 600 through the air supply hole 41. The purpose of the first hole 4 is to eliminate static electricity on the running wheel 200, which facilitates the adsorption of particles into the collection hole 1 by the adsorption port.
[0052] Specifically, the first hole 4 is connected to the air supply hole 41, and the gas passed through the static eliminator can be transported into the first hole 4 through the second interface 52. The airflow of the gas is very small. The gas escapes from the air supply hole 41 through the first hole 4 and contacts the walking wheel 200. The gas can eliminate the static electricity on the walking wheel 200, and the particles on the walking wheel 200 can easily detach from the walking wheel 200 and can be sucked into the adsorption hole 3.
[0053] The first adsorption hole 31 is located near the running wheel 200 and between the running wheel 200 and the baffle 400. The air supply hole 41 is located near the inner side of the running wheel 200. When the collection hole 1 draws air, due to the obstruction of the baffle 400, the collection hole 1 not only draws the air directly above, but also draws the air inside through the running wheel 200 and the running surface outward. In this way, the gas released by the first hole 4 for static elimination can easily come into contact with the running wheel 200, and the particles on the running wheel 200 can easily break away from the running wheel 200 and be sucked into the collection hole 1.
[0054] The method for transporting static electricity to eliminate the walking wheel 200 into the first hole 4 can be to connect a fan at the end of the track body 600 and set an electrostatic eliminator at the air supply point of the fan, or to directly connect the second interface 52 to the factory's air for eliminating static electricity to transport the electrostatic eliminator to the air supply hole 41.
[0055] In some embodiments, a plurality of first adsorption holes 31, second adsorption holes 32, and air supply holes 41 are provided, respectively, and are distributed on the track body 600 along the length direction of the first collection hole 11, the third collection hole 13, and the first hole 4, respectively. When the adsorption holes 3 and the air supply holes 41 are evenly spaced or extended along the length direction of the track, the negative pressure of the adsorption holes 3 near the ends of the track body 600 is greater than the negative pressure of the adsorption holes 3 near the middle of the track body 600. The air supply pressure of the adsorption holes 3 near the ends of the track body 600 is greater than the air supply pressure of the adsorption holes 3 near the middle of the track. This results in a gradual decrease in the air intake and air supply volumes from the ends of the track body to the middle of the track body, and a poorer effect of collecting particles in the middle of the track.
[0056] In order to solve the above technical problems, in the present application, the size and / or number of the openings of the adsorption holes 3 and the air supply holes 41 are set. Specifically, the apertures of the adsorption holes 3 and the air supply holes 41 near the middle of the track body 600 are larger than the apertures of the adsorption holes 3 near the ends of the track body 600, and the apertures of the adsorption holes 3 and the air supply holes 41 gradually decrease from the middle of the track body 600 to the two ends of the track body 600, that is, the apertures of the adsorption holes 3 and the air supply holes 41 located in the middle of the track body 600 are the largest, and as the position of the hole setting gradually approaches the two ends of the track body 600, the apertures gradually decrease. By increasing the apertures of the adsorption holes 3 and the air supply holes 41 located in the middle of the track body 600, the air supply volume and the air suction volume in the middle of the track are increased, so that the adsorption volume and the air supply volume in the middle and at both ends of the track body 600 are basically the same.
[0057] Alternatively, the distance between two adjacent adsorption holes 3 / air supply holes 41 near the middle of the track body 600 is smaller than the distance between two adjacent adsorption holes 3 / air supply holes 41 near the ends of the track body 600. That is, the distance between two adjacent adsorption holes 3 / air supply holes 41 located in the middle of the track body 600 is the smallest. As the location of the adsorption holes 3 / air supply holes 41 approaches the two ends of the track body 600, the distance between the two adjacent adsorption holes 3 / air supply holes 41 gradually increases. By reducing the distance between the adsorption holes 3 / air supply holes 41 located in the middle of the track body 600, the density of the adsorption holes 3 / air supply holes 41 located in the middle of the track body 600 is increased, and the air supply and suction volumes in the middle of the track body 600 are increased, so that the adsorption and air supply volumes in the middle and at both ends of the track body 600 are basically the same.
[0058] The aperture and number of the adsorption holes 3 / air supply holes 41 can be set at the same time, or the aperture or number of the adsorption holes 3 / air supply holes 41 can be set separately to achieve basically the same adsorption amount and air supply amount of the adsorption holes 3 / air supply holes 41.
[0059] On the other hand, the above technical problems can be solved by providing a plurality of first interfaces 51 and second interfaces 52 on the outer side surface of the track body 600. Specifically, a plurality of first interfaces 51 are provided along the length direction of the collection hole 1, the first interface 51 is connected to the collection hole 1, and the first interface 51 is connected to the negative pressure mechanism located outside the track body 600. By providing a plurality of first interfaces 51, the gas in the second collection hole 12 can be evenly sucked at intervals, and the negative pressure of the first adsorption holes 31 and the second adsorption holes 32 at various locations of the track body 600 is also basically the same. When the first adsorption holes 31 and the second adsorption holes 32 are arranged or extended at intervals along the length direction of the track, the air suction volume of the first adsorption holes 31 and the second adsorption holes 32 at various locations is basically the same, which can avoid the situation where the effect of collecting particles in the middle of the track is poor when air is only sucked at the ends of the track.
[0060] In some embodiments, second interfaces 52 are arranged along the length of first aperture 4, communicating with first aperture 4 and connected to an electrostatic eliminator located outside track body 600. By providing multiple second interfaces 52, gas can be uniformly delivered to the track at intervals. By exchanging heat between multiple first interfaces and multiple second interfaces, the adsorption and gas delivery rates can be substantially consistent in the middle and ends of track body 600.
[0061] In some embodiments, a QR code for positioning the overhead crane 100 is affixed to the lower surface of the track. The overhead crane 100 can be accurately positioned at the position where the process machine needs to pick up and place the wafer box through the QR code. Therefore, by arranging the first interface 51 and the second interface 52 on the outer side of the track body 600, the external pipelines connecting the negative pressure mechanism and the air supply mechanism are located on the outer side of the track body 600, which can avoid the area on the lower surface of the track body 600 from being occupied, and prevent the external pipelines from blocking the QR code.
[0062] See attached Figure 4 As shown, in some embodiments, the overhead crane track further includes a baffle 400, one end of which is detachably connected to the outer side surface of the track body 600 via a connecting mechanism 800, and the other end extends toward the overhead crane 100. The overhead crane track further includes a cleaning member 900 disposed on the baffle 400, which abuts against the running wheels 200 of the overhead crane 100. The cleaning member 900 can clean the running wheels 200, and the cleaning member 900 is a wheel brush, a clean cloth, etc. The overhead crane track of the present application can also be used as a maintenance track, which is connected to the working track of the overhead crane. When the overhead crane 100 needs to be cleaned, the overhead crane 100 enters the maintenance track from the working track, and the wheel brush can sweep away the particles on the running wheels 200, and the first adsorption hole 31 and the second adsorption hole 32 can suction and remove the swept particles.
