Background Technology

[0002] Raised floors are now widely used in computer rooms, clean rooms, and other similar spaces. A raised floor typically consists of at least four legs, at least four crossbeams, and at least one floor unit. It provides a highly flat surface above the floor, facilitates the installation of piping, and allows for easy control of cleanliness levels. The floor unit is a crucial structural element of the entire factory building. However, conventional methods for measuring floor units mostly rely on manual measurement, which is both time-consuming and costly.

[0003] To address the aforementioned issues, the designers in this case disclosed various measuring devices in Taiwan Patents Nos. TWM659935, TWM658755, and TWM658754. However, these three patents did not consider errors caused by poor squareness of the measured floor unit, thus leaving room for improvement.

[0004] In view of this, the designer of this case pondered deeply, actively researched, and combined with many years of experience in related product research, and through continuous experimentation and improvement, finally developed this utility model. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a side length measuring device for a raised floor unit, comprising: a first platform; a clamping mechanism disposed on the first platform for clamping a floor unit on the first platform; the clamping mechanism having a front positioning structure and a left positioning structure to define a front reference line and a left reference line that are perpendicular to each other; a third side length measuring device disposed on the rear side of the first platform; a fourth side length measuring device disposed on the rear side of the first platform; a fifth side length measuring device disposed on the right side of the first platform; and a sixth side length measuring device disposed on the right side of the first platform; the error data of the side length is obtained by subtracting the measurement information obtained by the third side length measuring device and the fourth side length measuring device, and the error data of the side length is obtained by subtracting the measurement information obtained by the fifth side length measuring device and the sixth side length measuring device.

[0007] Preferably, the clamping mechanism has two front fixed roller seats and two rear sliding roller seats.

Then, the data is measured by the third side length measuring device and the fourth side length measuring device, which can conveniently use the front edge of the floor unit as the measurement reference.

[0008] Preferably, the error data for the side length is obtained by subtracting the measurement information obtained from the third and fourth side length measuring devices.

[0009] Preferably, the clamping mechanism has two left fixed roller seats and one right sliding roller seat. The right sliding roller seat pushes the floor unit to the two left fixed roller seats, so that the left edge of the floor unit overlaps with the left reference line. Then, the data is measured by the fifth side length measuring device and the sixth side length measuring device, which can conveniently use the left edge of the floor unit as the measurement reference.

[0010] Preferably, the error data of the side length is obtained by subtracting the measurement information obtained from the fifth side length measuring device and the sixth side length measuring device.

[0011] Preferably, the first platform is provided with a floor sensor facing the floor unit; the floor sensor is used to activate the clamping mechanism and the third to sixth side length measuring devices only when it senses that the floor unit has been installed on the first platform.

[0012] Preferably, the first platform is equipped with an automatic floor barcode scanner facing the floor unit; a floor code is set at a predetermined position in the floor unit, and the automatic floor barcode scanner can scan to obtain the floor code, so that the measured side length and the corresponding floor code can be stored together conveniently.

The rear pushing mechanism may be composed of two rear sliding roller seats, and the right pushing mechanism may be composed of a right sliding roller seat, which can prevent the floor unit from being damaged by friction around its perimeter.

[0014] Preferably, the rear sliding roller seat and the right sliding roller seat can be respectively composed of a slide rail base with a slide rail on the top, a sliding base slidably disposed on the slide rail base, a roller rotatably disposed on the sliding base, and a pneumatic cylinder that drives the sliding base to move closer to or away from the floor unit along the slide rail of the slide rail base, which can prevent the floor unit from being damaged by friction around its perimeter.

Detailed Implementation

[0026] like Figures 1 to 8 As shown, this utility model provides a side length measuring device 100 for a raised floor unit, comprising: a first platform 1; a clamping mechanism 2 disposed on the first platform 1 to clamp a floor unit 101 on the first platform 1; the clamping mechanism 2 has a front positioning structure 21 and a left positioning structure 22 to define a mutually perpendicular front reference line L11 and a left reference line L12; a third to a sixth side length measuring device 33, 34, 35, and 36 located on the same plane and arranged on the rear and right sides of the floor unit 101; a side length measuring means that can more accurately measure the side length of the floor unit. This will be described in detail below.

[0027] This utility model can be used to measure, for example, honeycomb floor units (not shown in the figure), grid floor units (not shown in the figure), window floor units (not shown in the figure), blind floor units (hereinafter referred to as blind plates, this utility model takes blind plates as an example) and other types of floor units 101.

[0028] The first platform 1 can be a steel frame structure. Figures 2-8 The image is simply illustrated with a flat panel.

[0029] like Figures 1-2 As shown, the front positioning structure 21 of the clamping mechanism 2 can be composed of two front fixed roller seats 211. The two front fixed roller seats 211 form the front reference line L11. In addition, the left positioning structure 22 can be composed of two left fixed roller seats 221, and the two left fixed roller seats 221 form a left reference line L12 perpendicular to the front reference line L11.

[0030] like Figure 3 As shown, the clamping mechanism 2 may further include a rear pushing mechanism 23 and a right pushing mechanism 24. The rear pushing mechanism 23 may be composed of two rear sliding roller seats 231, and the right pushing mechanism 24 may be composed of a right sliding roller seat 241. These mechanisms can push the floor unit 101 from the rear and right sides respectively, causing the front edge 1011 and left edge 1012 of the floor unit to rest against the two front fixed roller seats 211 and the two left fixed roller seats 221, thereby fixing the floor unit 101 for measurement. After measurement, the rear pushing mechanism 23 and the right pushing mechanism 24 can be returned to their original positions for easy replacement of the floor unit 101 under test.

[0031] like Figures 3-5 As shown, the two front fixed roller seats 211 and the two left fixed roller seats 221 have the same structure. Taking the front fixed roller seat 211 as an example, it can be composed of a base 2111 and a roller 2112 rotatably mounted on the base.

[0032] The rear sliding roller seat 231 and the right sliding roller seat 241 have the same structure. Taking the right sliding roller seat 241 as an example, it can be composed of a slide rail base 2411 with a slide rail 2412 on the top, a sliding base 2413 slidably mounted on the slide rail base, a roller 2414 rotatably mounted on the sliding base, and a pneumatic cylinder 2415 that drives the sliding base 2413 to move closer to or away from the floor unit 101 along the slide rail 2412 of the slide rail base 2411. With this structure, friction damage to the perimeter of the floor unit 101 can be avoided when the clamping mechanism 2 pushes the floor unit 101.

[0033] The third to sixth side length measuring devices 33, 34, 35, and 36 have the same structure. Taking the fifth side length measuring device 35 as an example, it may have: a side length base 351, fixed on the first platform 1, with a slide rail 352 on the side length base; a side length displacement gauge 353, slidably mounted on the slide rail of the side length base; and a side length pneumatic cylinder 354, which drives the side length displacement gauge to move closer to or away from the floor unit along the slide rail.

[0034] The front edge 1011 of the floor unit 101 overlaps with the front reference line, and the left edge 1012 can also overlap with the left reference line, thus serving as the main reference for measurement. Therefore, at least the third to sixth side length measuring devices 33, 34, 35, and 36 need to be installed on the rear and right sides of the floor unit to complete the measurement. For example, the third side length measuring device 33 measures the rear edge of the floor unit near the left side; the fourth side length measuring device 34 measures the rear edge of the floor unit near the right side; the fifth side length measuring device 35 measures the right side edge of the floor unit near the front; and the sixth side length measuring device 36 measures the right side edge of the floor unit near the rear.

[0035] The side length measuring device 100 of the raised floor unit may further include a controller. The controller may be, for example, a computer or a programmable logic controller (PLC) (not shown in the figure), for controlling the clamping mechanism 2, the third to sixth side length measuring devices 33, 34, 35, 36 and other components.

[0036] The side length measurement method can be a program code recorded in the controller, which obtains the lengths of the front edge 1011, left edge 1012, rear edge 1013, and right edge 1014 of the floor unit based on the measurement results of the third to sixth side length measuring devices 33, 34, 35, and 36. Based on this structure, this utility model further discloses a method for measuring the side length of a raised floor unit. The method for measuring the side length of a raised floor unit of this utility model includes at least the following steps (S10) to (S15).

[0037] This utility model uses a clamping mechanism 2 to clamp the floor unit 101, so it can be used to measure floor units of various different sizes and specifications. Therefore, when measuring floor units of the same size and specification, a sample plate that conforms to the standard size can be used to perform zeroing operations first.

[0038] S10) A clamping mechanism 2 is used to make the front edge 1011 of a floor unit 101 overlap with a front reference line L11. In step S10), the floor unit 101 can be pushed by two rear sliding roller seats 231, so that the front edge 1011 of the floor unit 101 rests on two front fixed roller seats 211, thereby making the front edge 1011 overlap with the front reference line L11.

[0039] S11) A third side length measuring device 33 measures the rear edge 1013 of the floor unit 101 near the left side to obtain first side length measurement information, and a fourth side length measuring device 34 measures the rear edge 1013 of the floor unit 101 near the right side to obtain second side length measurement information. For example... Figure 6 As shown, in step S11), the side length displacement gauge is driven close to the floor unit by the side length pneumatic cylinders of the third to fourth side length measuring devices 33 and 34, thereby completing the measurement.

[0040] S12) The length of the left edge 1012 of the floor unit is obtained using a side length measurement method based on the first side length measurement information and the front reference line, and the length of the right edge 1014 of the floor unit is obtained based on the second side length measurement information and the front reference line; the clamping mechanism 2, the third side length measuring device 33, and the fourth side length measuring device 34 return to their original positions (e.g., Figure 3 (As shown).

[0041] S13) The clamping mechanism 2 is used to make the left edge 1012 of the floor unit 101 overlap with a left reference line L12. In step S13), the floor unit 101 can be pushed by the right sliding roller seat 241 so that the left edge 1012 of the floor unit 101 rests against the left fixed roller seat 221, thereby making the left edge 1012 overlap with the left reference line L12.

[0042] S14) A fifth side length measuring device 35 measures the position of the right edge 1014 of the floor unit near the front to obtain third side length measurement information, and a sixth side length measuring device 36 measures the position of the right edge 1014 of the floor unit near the rear to obtain fourth side length measurement information. Figure 7 As shown, in step S14), the side length displacement gauge is driven close to the floor unit by the side length pneumatic cylinder of the fifth to sixth side length measuring instruments 35 and 36, thereby completing the measurement.

[0043] S15) The length of the front edge 1011 of the floor unit is obtained by the side length measurement method based on the third side length measurement information and the left baseline, and the length of the rear edge 1013 of the floor unit is obtained based on the fourth side length measurement information and the left baseline; the clamping mechanism 2, the fifth side length measuring device 35 and the sixth side length measuring device 36 return to the origin (e.g. Figure 3 (As shown).

[0044] As described in steps S10) to S15), when measuring the length of the front edge 1011 and the rear edge 1013 of the floor unit 101, the left edge 1012 and the left reference line L12 are used as the basis. When measuring the length of the left edge 1012 and the right edge 1014 of the floor unit 101, the front edge 1011 and the front reference line L11 are used as the basis. This can reduce the error caused by possible poor squareness and obtain a more accurate side length of the floor unit 101. Furthermore, when measuring the side length, the floor unit is first pushed to the front fixed roller seat 211 by the two rear sliding roller seats 231, so that the front edge 1011 overlaps with the front reference line L11. The error data of the side length can be obtained by subtracting the measurement information obtained by the third side length measuring device 33 and the fourth side length measuring device 34. Then, the rear sliding roller seat 231, the third side length measuring device 33 and the fourth side length measuring device 34 are returned to the origin. Then, the floor unit is pushed to the left fixed roller seat 221 by the right sliding roller seat 241, so that the left edge 1012 overlaps with the left reference line L12. The error data of the side length can be obtained by subtracting the measurement information obtained by the fifth side length measuring device 35 and the sixth side length measuring device 36. Then, the right sliding roller seat 241, the fifth side length measuring device 35 and the sixth side length measuring device 36 are returned to the origin to facilitate subsequent measurements. For example, consider a floor unit with a standard size of 600x600mm. Before measurement, a sample board with four sides of 600x600mm is used for zeroing, and then the measurement begins. Taking a floor unit under test as an example, if the measurement information errors of the third side length measuring device 33 and the fourth side length measuring device 34 are 0.05 and -0.05 respectively, and 0.05-(-0.05)=0.1mm, then the side length of this side of the floor unit under test is 600-0.1=599.9mm. The other side length is measured in the same way. The method for determining the side length can also be the program code recorded in the controller, which can determine whether the side length of the floor unit under test is qualified within a tolerance range of, for example, 600x600±0.1mm. Both sides must be qualified.

[0045] like Figure 8As shown, a floor sensor 13 and / or an automatic floor barcode scanner 14 facing the floor unit 101 may also be provided on the first platform 1. The floor sensor 13 is used to activate components such as the clamping mechanism 2 and the third to sixth side length measuring devices 33, 34, 35, and 36 only when it senses that a floor unit 101 has been set on the first platform 1, so as to perform the aforementioned method for measuring the side length of the floor unit of the raised floor. In addition, a floor code (not shown in the figure) for each floor unit 101 may be set at a predetermined position on the floor unit 101. The automatic floor barcode scanner 14 can scan and obtain the floor code, so as to facilitate the storage of the measured side length and the corresponding floor code together for subsequent work.

[0046] The above description is merely a preferred embodiment of this utility model and is provided for ease of explanation only. It should not be construed as limiting the significance of this utility model. All variations and designs made based on this utility model should be included within the patent scope of this utility model.
