[0002] Currently, semiconductor factories frequently transport raw materials, and as a result, carts enter the factory very frequently. Therefore, the factory floor must bear a certain rolling load, otherwise the floor will easily break, causing the carts to shake during transportation, resulting in damage to the raw materials inside the carts.

[0003] Therefore, how to ensure that the quality of the floor can withstand high rolling loads has become a difficult problem that the industry urgently needs to overcome. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the conventional technology, the present invention provides an automated rolling test equipment, which includes: a carrier; a plurality of reference parts, which are separately arranged on the carrier to define a receiving area for placing a target object; a roller device, which is mounted on the carrier in a displaceable manner and is located above the receiving area; and a transport device, which is mounted on the carrier in a displaceable manner to place at least one counterweight on the roller device.

[0005] In the aforementioned automated rolling test equipment, the carrier is provided with a placement rack for placing the counterweight, so that the transport device transports the counterweight to the roller device and the placement rack.

[0006] In the aforementioned automated rolling test equipment, the reference member is a plate.

[0007] In the aforementioned automated rolling test equipment, the structure of the reference member is the same as that of the target object.

[0008] In the aforementioned automated rolling test equipment, the roller device includes a carrying box, a supporting base disposed below the carrying box, and a roller disposed below the supporting base, so that the roller can roll the target object in the receiving area. For example, the transport device places the counterweight on the supporting base, with the counterweight and the roller located on different sides of the supporting base. Alternatively, the carrying box is equipped with a plurality of guide rods, so that the carrying seat is connected to a carrying plate located above the carrying box through the plurality of guide rods, and the roller device further includes a lifting mechanism for displacing the carrying seat, and the lifting mechanism includes a plurality of intermediate circular flange linear bearings connected to the upper end of the guide rod, a circular flange linear bearing provided at the lower end of the guide rod, and an oil pressure or pneumatic cylinder for actuating the carrying seat, wherein the intermediate circular flange linear bearing and the circular flange linear bearing provided at the lower end of the guide rod are respectively fixed to the upper cover plate and the lower cover plate of the carrying box, and the oil pressure or pneumatic cylinder is fixed in the partition of the carrying box, so that the push rod end of the oil pressure or pneumatic cylinder passes through the carrying box to connect to the carrying plate, so as to lift the carrying seat and make the roller approach or move away from the target object. Alternatively, the roller device further includes a bearing plate, which is used to carry the counterweight so that the bearing plate and the roller are located on different sides of the bearing seat respectively, the roller is located on the lower side of the bearing seat, and the bearing plate is located on the upper side of the bearing seat. The bearing plate is arranged on the upper side of the bearing seat through a plurality of guide rods, and the plurality of guide rods pass through the bearing box up and down, so that the upper end of the guide rod is connected and fixed to the bearing plate through a bearing seat, and the lower end of the guide rod is fixed to the bearing seat through another bearing seat.

[0009] The aforementioned automated rolling test equipment further includes a displacement device for displacing the roller device so that the roller device moves on the reference part and the target object. For example, the displacement device includes a track assembly for mounting the roller device and an actuating assembly for pushing and pulling the roller device. Furthermore, the track assembly has two frames fixed to the carrier at the front and rear by two frames, and four guide rails fixed to the frame, wherein two guide rails are fixed upward to the upper end surface of the frame, and the other two guide rails are fixed outward to the bottom of the frame, and the actuating assembly is a ball screw assembly, the screw of which is connected to the roller device through a nut fixing seat, and one end of the screw is fixed to the carrier through a bearing seat, and the other end is connected to a power source fixed to the carrier through another bearing seat, so that the power source drives the screw to rotate, so that the nut fixing seat drives the roller device to move linearly.

[0010] In the aforementioned automated rolling test equipment, the transport device includes a support component displaceably mounted on the carrier, and at least one pick-and-place component displaceably mounted on the support component. The pick-and-place component includes a clamping member and a power unit for actuating the clamping member, so that the pick-and-place component is used to pick up and place the counterweight, and the pick-and-place component cooperates with the support component to move to move the counterweight to the roller device. For example, the support assembly is a gantry-type frame structure having two sets of support rods erected on the front and rear sides of the platform and a crossbeam spanning between the two sets of support rods, and the support rods are fixed to a fixed plate from the side, the power unit is fixed to one end of a gear set housing, the other end of the gear set housing is fixed to the fixed plate, and a track for guiding the displacement of the support assembly is arranged on the side of the platform, the track engages the gear set of the power unit, so that the power unit rotates its gear set to cause the gear set to roll along the track, thereby linearly displacing the support rods, so that the transport device can linearly displace on the track after clamping the counterweight. Furthermore, the clamping member is configured with a plurality of sliders, and the support assembly is provided with a slide rail engaging the sliders.

[0011] From the above, it can be seen that the automated rolling test equipment of the present invention mainly uses the transportation device to place the counterweight on the roller device to automatically perform the preliminary steps of the test operation, and by separately arranging the reference parts on the carrier to define the accommodation area for placing the target object such as the floor, and then the roller device is mounted on the carrier in a movable manner and located above the accommodation area. Therefore, when performing the test operation, it is only necessary to let the roller device equipped with the counterweight roll the target object in the accommodation area to test whether the target object can withstand the rolling of the roller device. Therefore, the automated rolling test equipment of the present invention can effectively test the bearing capacity of the target object to avoid losses at the application end due to defects in the target object.

[0028] Figure 1A 、 1B 1C, 1D, 1E and 1F are schematic diagrams of the automated rolling test equipment 1 of the present invention. Figures 1A to 1FAs shown, the automated rolling test equipment 1 includes: a carrier 10, two reference members 11 separately arranged on the carrier 10, a roller device 12 arranged on the carrier 10, and a transportation device 13 arranged on the carrier 10.

[0029] The carrier 10 is a rectangular platform with a supporting surface S on the bottom side for supporting a target 9 (such as Figure 2A floor shown).

[0030] In this embodiment, the platform 10 is a frame structure, generally composed of a plurality of beams, forming a rectangular table. For example, the automated rolling test apparatus 1 defines the direction along the short side of the platform 10 as the front and rear directions (e.g., arrow direction X), the direction along the long side of the platform 10 as the left and right directions (e.g., arrow direction Y), and the direction along the height of the platform 10 as the up and down directions (e.g., arrow direction Z). It should be understood that these directions are used to illustrate the configuration of this embodiment and are not particularly limiting.

[0031] Furthermore, the upper frame of the platform 10 is provided with a plurality of racks 10a and 10b for accommodating a plurality of counterweights 122. The roller device 12 is disposed on one side, and the transport device 13 is disposed on the other side. For example, the counterweights 122 are plates that can be rectangular, square, circular, or other suitable shapes, and can have weights ranging from 40 to 60 kilograms or 90 to 120 kilograms. Specifically, the counterweights 122 accommodated on the racks 10a and 10b have different specifications (weights). For example, one rack 10a accommodates counterweights 122 weighing 40 to 60 kilograms, while the other rack 10b accommodates counterweights 122 weighing 90 to 120 kilograms.

[0032] Furthermore, the automated rolling test equipment 1 may be equipped with a power device 14 on the lower side of the carrier 10 . The power device 14 may include, for example, a hydraulic system and other related equipment to provide the power required for the movement of the transport device 13 .

[0033] In addition, the automated rolling test equipment 1 can be equipped with a displacement device 15 for displacing the roller device 12, so that the roller device 12 moves above the supporting surface S along the left and right directions (such as the arrow direction Y) of the carrier 10. Specifically, the displacement device 15 includes a track component 15a for mounting the roller device 12 and an actuating component 15b for pushing and pulling the roller device 12. For example, the track component 15a has two pieces connected by two frames 154 (such as Figure 1A and 1BThe front and rear of the frame 150 are fixed on the carrier 10, and four guide rails 151 are fixed on the frame 150, two of which are fixed upward on the upper end surface of the frame 150, and the other two guide rails 151 are fixed outward on the bottom of the frame 150, and the actuating component 15b is a ball screw group, the screw 152 of which is fixed by a nut fixing seat 153 (as shown in FIG. Figure 1C ) engages the roller device 12, and one end of the screw 152 is supported by a bearing seat 152a (as shown Figure 1A ) is fixed to the carrier 10, and the other end is connected to a power source 15c (as shown) fixed to the carrier 10 through another bearing seat 152b. Figure 1A The servo motor shown in FIG. 1 is used to drive the power source 15c to drive the screw 152 to rotate, so that the nut fixing seat 153 drives the roller device 12 to move linearly.

[0034] The reference member 11 defines the spaced area between the two as a receiving area A for placing the target object 9 .

[0035] In this embodiment, the reference member 11 is a plate. For example, the reference member 11 is a floor, and its structure is the same as that of the target object 9. Specifically, when performing the test operation, the top surface 11a of the reference member 11 is flush with the top surface 9a of the target object 9, such as Figure 2B shown.

[0036] Furthermore, the carrying surface S of the carrier 10 may be provided with hollow areas facing forward and backward, such as Figure 1A and 1B As shown, it is convenient to take and place the reference member 11 and the target object 9.

[0037] The roller device 12 is mounted on the carrier 10 in a displaceable manner and is located above the reference members 11 and the accommodating area A.

[0038] In this embodiment, the roller device 12 is modeled after a cart structure, such as Figure 1B As shown, it includes a carrying box 12a, a carrying base 120 disposed below the carrying box 12a, and a roller 121 disposed on the carrying base 120. Specifically, the carrying base 120 is a rectangular plate, and the roller 121 is disposed at the center thereof, and the roller 121 is in a single rolling direction (as shown by the arrow direction Y).

[0039] Furthermore, the carrying box 12a is a rectangular box with a partition 126 disposed therein. Figure 1DAs shown, the left and right sides of the carrying box 12a are through-through for the frame 150 of the track assembly 15a of the displacement device 15 to pass through, and a plurality of sliders 124 (such as Figure 1C As shown, the screw 152 of the actuating assembly 15b passes through the through-hole 1260 of the partition 126, and the nut fixing seat 153 is fixed to the center of the partition 126 of the carrying box 12a. Therefore, when the screw 152 rotates, the nut fixing seat 153 can move linearly in the left and right directions (as shown in the arrow direction Y), thereby causing the carrying box 12a to move forward and backward in a linear manner in coordination with the track assembly 15a, so that the carrying box 120 and the roller 121 thereon can move linearly in the left and right directions (as shown in the arrow direction Y). Furthermore, by disposing the bearing seats 152a and 152b on the left and right sides of the displacement device 15, respectively, the movement range of the carrying box 12a is limited, thereby preventing excessive displacement of the carrying box 120.

[0040] Furthermore, the roller device 12 further includes at least one supporting plate 125 provided on the supporting seat 120 for supporting the counterweight 122, so that the supporting plate 125 and the roller 121 are respectively located on different sides of the supporting seat 120, so that the counterweight 122 provides the required target pressure F (such as Figure 2B As shown in FIG. 1 , the roller 121 (or the supporting base 120) is provided. For example, the roller 121 is located at the lower side of the supporting base 120, and the supporting plate 125 is located at the upper side of the supporting base 120 (or the supporting box 12a). Specifically, the supporting plate 125 can be guided by a plurality of (e.g., four) guide rods 125a (e.g., Figure 1C ) is provided on the upper side of the bearing seat 120, and the guide rods 125a are passed through the bearing box 12a up and down, so that the upper end of the guide rod 125a is supported by the bearing seat 125b (as shown Figure 2B ) is connected and fixed to the supporting plate 125, and the lower end of the guide rod 125a is also connected to the supporting plate 125 by the bearing seat 125c (as shown Figure 2B ) is fixed on the supporting base 120. Therefore, the size of the target pressure F can be adjusted by using counterweights 122 of different weights and increasing or decreasing the number of the counterweights 122.

[0041] In addition, the roller device 12 further includes a lifting mechanism 123 for displacing the supporting base 120. Figure 1CAs shown, the support base 120 is lifted and lowered along the up and down directions (such as the arrow direction Z) to make the roller 121 approach or move away from the reference parts 11. For example, the lifting mechanism 123 includes a plurality of intermediate circular flange linear bearings 123b connected to the upper end of the guide rod 125a, a circular flange linear bearing at the lower end of the guide rod 125a (not shown) and an oil pressure or pneumatic cylinder 123a for actuating the support base 120, wherein the intermediate circular flange linear bearing 123b and the circular flange linear bearing at the lower end of the guide rod 125a are respectively fixed to the upper cover plate and the lower cover plate of the support box 12a, and the oil pressure or pneumatic cylinder 123a is fixed in the partition 126 of the support box 12a above the through hole 1260 (such as Figure 1D 2B ). Specifically, the hydraulic system of the power unit 14 provides the power required by the hydraulic or pneumatic cylinder 123a, so that the hydraulic or pneumatic cylinder 123a can lift the bearing plate 125 and the counterweight 122 thereon, and the guide rod 122a and the intermediate circular flange linear bearing 123b can cooperate to lift the bearing seat 120 and the roller 121 thereon, so that the roller 121 can contact (as shown in FIG. Figures 3A to 3C as shown) or separated (as Figure 2B ) top surfaces 11 a of the reference members 11 and the top surface 9 a of the target object 9.

[0042] The transport device 13 is mounted on the carrier 10 in a displaceable manner to place at least one counterweight 122 on the supporting plate 125 on the roller device 12 .

[0043] In this embodiment, the transport device 13 includes a support component 13a displaceably arranged on the carrier 10, and at least one pick-up and placement component 13b displaceably arranged on the support component 13a, so that the pick-up and placement component 13b is used to pick up and place the counterweight 122, and the pick-up and placement component 13b cooperates with the support component 13a to move to move the counterweight 122 to the supporting plate 125 of the roller device 12.

[0044] Furthermore, the support assembly 13a is a gantry frame structure, such as Figure 1A and 1B As shown, it has two sets of support rods 130 erected on the front and rear sides of the carrier 10 and a crossbeam 131 spanning between the support rods 130, and the displacement path of the support assembly 13a covers the upper part of the placement rack 10a and the carrier plate 125. Preferably, as Figure 1B and 1EAs shown, the support rod 130 is fixed to a fixed plate 130a from the side, a power unit 13c (such as a motor or drive motor) is fixed to one end of a gear assembly 133 housing, and the other end of the gear assembly 133 housing is fixed to the fixed plate 130a. In addition, a track 132 for guiding the displacement of the support assembly 13a can be disposed on the side of the carrier 10, such as a linear track structure such as a rack. The track engages the gear assembly 133 of the power unit 13c. The power unit 13c rotates its gear assembly 133, causing the gear assembly 133 to roll along the track 132 to linearly move the support rod 130 back and forth (as shown in the direction of arrow Y). Therefore, the transport device 13 can stably move linearly on the track 132 after clamping the counterweight 122. It should be understood that there are many types of support assembly 13a and there is no particular limitation.

[0045] Again, such as Figure 1A and 1B As shown, the pick-and-place assembly 13b includes a clamping member 134 and a power unit 135 for actuating the clamping member 134. For example, clamping jaws (not shown) are provided at both ends of the clamping member 134. The clamping jaws are controlled by a pneumatic cylinder or a hydraulic cylinder. The width of the clamping jaws can be adjusted as needed to clamp counterweights 122 of different widths. The power unit 135 is a pneumatic cylinder or a hydraulic cylinder actuated by the power device 14 to actuate the clamping member 134 to move up and down. Specifically, as shown in Figure 1F, the two opposite rod ends of the clamping member 134 are configured with a plurality of sliders 136 to engage with the slide rail 137 provided on the inner side of the support rod 130. Therefore, when the power unit 135 pushes down or pulls up the clamping member 134, the clamping member 134 can move up and down in a straight line along the slide rail 137 through the slider 136, so that the clamping member 134 is close to or away from the counterweight member 122.

[0046] Please also refer to Figure 2A and 2B When the automated rolling test equipment 1 is used for testing, a plurality of target objects 9 such as floors are first placed on the accommodation area A so that the target objects 9 and the two reference members 11 are arranged in a row and adjacent to the two reference members 11, and the roller device 12 is moved to the adjacent rack 10b by the displacement device 15. Then, the counterweights 122 on the racks 10a and 10b are clamped onto the supporting plate 125 of the roller device 12 by the transport device 13, wherein the weight of one counterweight 122 on the rack 10a is about 90 to 120 kilograms (kg), and the weight of one counterweight 122 on the rack 10b is about 40 to 60 kilograms (kg), and the number of the counterweights 122 is adjusted as needed (at least 250 kilograms) to provide a target pressure F to the roller 121. Afterwards, please refer to Figures 3A to 3CThe lifting mechanism 123 lowers the support base 120 so that the roller 121 contacts the reference member 11 on the left (eg Figure 3A As shown), the displacement device 15 pushes the carrying box 12a toward the right to drive the supporting base 120 to roll linearly toward the right, so that the roller 121 rolls the target object 9 (as shown). Figure 3B As shown), to test whether the target object 9 can withstand the target pressure F. When the roller 121 rolls to the right side of the reference member 11 (as shown), the target object 9 can withstand the target pressure F. Figure 3C As shown), the displacement device 15 pulls the carrying box 12a toward the left to drive the supporting base 120 to roll linearly toward the left, so that the roller 121 rolls the target object 9 again (as shown). Figure 3B Wait until the roller 121 rolls to the left side of the reference member 11 (as shown). Figure 3A As shown), the rolling test of the target object 9 is completed once. The back-and-forth rolling test must be performed multiple times according to the above steps, and according to the standard specifications, at least 10,000 back-and-forth rolling tests must be performed.

[0047] If the roller 121 does not crush the target object 9 or scratch the top surface 9a of the target object 9, it means that the target object 9 can withstand the target pressure F, so the test result of the target object 9 is qualified, that is, the quality of the target object 9 is good; on the contrary, if the roller 121 crushes the target object 9 or scratches the top surface 9a of the target object 9, it means that the target object 9 cannot withstand the target pressure F, so the test result of the target object 9 is unqualified, that is, the quality of the target object 9 is poor.

[0048] Preferably, an indicator gauge 8 can be placed at the center of the lower side of the target object 9 to confirm the target pressure F (such as Figures 3A to 3C shown).

[0049] On the other hand, if the counterweight 122 is not provided, the automated rolling test apparatus 1 is used to detect the movement load of the target object 9 solely on the supporting base 120 and the roller 121 .

[0050] It should be understood that the user can operate a human-machine interface (not shown) to control the automated rolling test equipment 1 to perform the test operation.

[0051] In summary, the automated rolling test equipment 1 of the present invention mainly uses the transport device 13 to take and place the counterweight 122 on the roller device 12 to automatically perform the pre-test step, and by separating and arranging the reference members 11 on the carrier 10 to define the accommodation area A for placing the target object 9 such as the floor, and then the roller device 12 is mounted on the carrier 10 in a movable manner and located above the accommodation area A. Therefore, during the test operation, the roller device 1 The roller 121 of 2 rolls the target object 9 in the accommodating area A to test whether the target object 9 can withstand the rolling load (such as the target pressure F) of the roller device 12 (which can optionally include the weight of the counterweight 122). Therefore, the automated rolling test equipment 1 can effectively test the rolling load that the target object 9 can withstand, so that when the target object 9 is used on the floor of a semiconductor factory, it can avoid losses at the application end (such as the conventional use of a cart to transport semiconductor raw materials) due to defects of the target object 9.

[0052] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present profession can make slight changes or modifications to equivalent embodiments of equivalent changes using the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
