[0001] The present invention relates to measuring equipment and a lifting mechanism, and particularly to a lifting mechanism and flatness measuring equipment for a raised floor.

Background Art

[0002] [[ID=II]] A raised floor is a floor system widely used in semiconductor factories, offices, computer rooms, etc., and is basically composed of a support frame and a plurality of floor panels with adjustable height. These floor panels are raised from the ground to form a space for arranging equipment such as electric wires, cables, pipes, etc., and can assist in improving ventilation and heat dissipation.

[0003] In order to ensure that the surface of the entire floor is flat, it is necessary to inspect the flatness of the raised floor and avoid errors and structural problems after installation. The method of measuring the flatness of a raised floor usually inspects the flatness by visual inspection of a horizontal line, and requires comparison of two or more points during operation. There is also a method of using a straightedge (flat ruler) or a measuring rod and placing it on the raised floor to inspect the flatness of the floor. Place the straightedge at different positions on the floor and check whether the straightedge touches the ground. If there is an uneven part, it means there is a problem with the flatness. However, these methods often consume manpower and depend on the experience and judgment of on-site process personnel, resulting in a decrease in overall process efficiency.

[0035] Figure 1 is a perspective view of the flatness measuring equipment for a raised floor according to the present invention. Figure 2 is a perspective view of one embodiment of the raised floor according to the present invention, and Figure 3 is a partial perspective view of the flatness measuring equipment for a raised floor according to the present invention, in which the measuring device 52 is omitted in order to show the positioning device 53 and the lifting device 54 of the raised floor. Referring to Figures 1 to 3, the flatness measuring equipment 50 for a raised floor according to the present invention is installed along the transport direction LA so as to include a standby station LA1, a measuring station LA2, and an output station LA3, with the measuring station LA2 located between the standby station LA1 and the output station LA3.

[0036] For example, the raised floor flatness measuring equipment 50 is suitable for measuring the flatness of the top plate 42 of the raised floor 40 by transmitting the data of the top plate 42 of the raised floor 40, as shown in Figure 2. The raised floor 40 is input from the standby station LA1 to the measurement station LA2, where the flatness of the top plate 42 of the raised floor 40 is measured, and the raised floor 40 after the flatness measurement is transmitted to the output station LA3.

[0037] The raised floor 40 of the present invention has a rectangular shape and comprises one top plate 42 and four side plates 44, each of which is perpendicularly connected to the four sides of the top plate 42. The dimensions of the raised floor 40 of the present invention are, for example, 600 mm × 600 mm × 60 mm, and it is made of a material such as aluminum alloy die-cast.

[0038] The flatness measuring equipment 50 for the raised floor includes a transport device 51, a measuring device 52, a positioning device 53, a lifting device 54 for the raised floor, and optionally a plurality of position regulating devices 55 and at least one positioning member 56, where the transport device 51 is used to transport the raised floor 40 along the transport direction LA as shown in Figure 2, and the transport device 51 includes a first frame 511, a second frame 512, and a transport structure 514.

[0039] The transport structure 514 of the transport device 51 has a transport direction LA and may include a standby station LA1, a measuring station LA2, and an output station LA3 along the transport direction LA. The first frame 511 and the second frame 512 are each provided below the transport structure 514, with the first frame 511 located at the standby station LA1 of the transport structure 514 and the second frame 512 located at the output station LA3 of the transport structure 514.

[0040] The measuring device 52, the positioning device 53, and the lifting device 54 for the raised floor are each located at the measuring station LA2 of the transport structure 514, and the measuring device 52, the positioning device 53, and the lifting device 54 for the raised floor are all located between the first frame 511 and the second frame 512. In this way, the raised floor 40 shown in Figure 2 can be transmitted from the first frame 511 located at the standby station LA1, through the transport structure 514, to the second frame 512 of the output station LA3.

[0041] In one embodiment, the transport structure 514 includes a main body 5142, a chain member 5144, a plurality of gear members including a first gear member 5146A and a second gear member 5146B, and a drive motor 5148. The main body 5142 is, for example, a frame, with a first frame 511 and a second frame 512 each provided below the main body 5142, the first gear member 5146A and the second gear member 5146B each provided at both ends of the main body 5142, the chain member 5144 connected to the first gear member 5146A and the second gear member 5146B respectively, and the drive motor 5148 connected to the second gear member 5146B.

[0042] When the drive motor 5148 drives the second gear member 5146B, the first gear member 5146A rotates in sync with the second gear member 5146B, and at the same time, the first gear member 5146A and the second gear member 5146B drive the chain member 5144 to move, causing the chain member 5144 to move along the transport direction LA.

[0043] In one embodiment, as shown in Figure 2, the back side 46 of the raised platform 40 can be positioned on the chain member 5144, and the raised platform 40 is transported from the standby station LA1 to the output station LA3 via the chain member 5144. Of these, the back side 46 refers to the side opposite to the top plate 42, that is, the top plate 42 of the raised platform 40 does not come into contact with the chain member 5144, and when the raised platform 40 is transported to the measurement station LA2 by the chain member 5144, the raised platform 40 is positioned between the chain member 5144 and the measuring device 52, that is, the top plate 42 of the raised platform 40 is positioned below the measuring device 52.

[0044] The first gear member 5146A and the second gear member 5146B described in this invention are, for example, two gears, and are provided at both ends of the main body 5142. The two chain members 5144 are each provided on the main body 5142. The chain members 5144 may include a chain, guide grooves, rollers, etc., but this invention does not limit the configuration of the chain members 5144. The drive motor 5148 includes a chain connecting the second gear member 5146B and causes the drive motor 5148 to rotate the second gear member 5146B. At the same time, when the second gear member 5146B rotates, the chain members 5144 rotate along with it. The rotation of the chain member 5144 causes the first gear member 5146A to rotate, and the first gear member 5146A and the second gear member 5146B rotate synchronously, achieving the objective that the conveying device 51 will carry at least one raised platform 40 and convey the raised platform 40 along the conveying direction LA.

[0045] Furthermore, in one embodiment, the flatness measuring equipment 50 for the raised floor can selectively install position regulating devices 55. As shown in Figure 1, two position regulating devices 55 are each located at the standby station LA1, and the two position regulating devices 55 are each installed on both sides of the transport structure 514. The installation height of the two position regulating devices 55 can be higher than the installation height of the chain member 5144.

[0046] The installation of the position restricting device 55 limits the height of the raised platform 40, ensuring that it can be positioned above the chain member 5144, thereby enabling the raised platform 40 to operate normally on the conveying device 51. The position restricting device 55 is, for example, a plate, and can be installed at any position on the conveying device 51 depending on the actual situation. That is, for example, in addition to installing the position restricting device 55 at the standby station LA1, it can also be installed at the measurement station LA2 or the output station LA3.

[0047] In one embodiment, the transport device 51 further includes a support frame 513, which is located between a first frame 511 and a second frame 512, and is located at the measuring station LA2 of the transport structure 514. The measuring device 52, the positioning device 53, and the lifting device 54 for the raised floor are each located above the support frame 513, and the measuring device 52, the positioning device 53, and the lifting device 54 for the raised floor are all located above the chain member 5144 of the transport structure 514, with the measuring device 52 being located above the positioning device 53 and the lifting device 54 for the raised floor.

[0048] Figure 4 is a perspective view of one embodiment of the measuring device according to the present invention. Figure 5 is a perspective view of one embodiment of the rear view of the measuring device according to the present invention. Figure 6A is a side view at one angle of one embodiment of the measuring device according to the present invention. Figure 6B is a side view at another angle of one embodiment of the measuring device according to the present invention. Referring to Figures 1, 4 to 6B, the measuring device 52 of the present invention is located at the measuring station LA2 of the transport structure 514, and the measuring device 52 is provided on the chain member 5144. For example, as shown in Figure 1, four connecting columns 5132 are connected on the support frame 513, and the bottom of the measuring device 52 is connected to each of the four connecting columns 5132, and the measuring device 52 is provided above the support frame 513. In one embodiment, both ends of each crossbar 5134 are connected and fixed to the support frame 513, respectively, to stabilize the position of the support frame 513.

[0049] The measuring device 52 includes a sensor fixing plate 522, multiple sensors 524, multiple probes 526, and four plate surface zero-point positioning blocks 528. The sensor fixing plate 522 is a disk body and includes opposing housing sections S1 and detection surfaces S2. The multiple sensors 524, or 37 sensors 524, are each installed at different positions in the housing section S1, with 5 sensors 524 on each of the four sides, for a total of 25 sensors 524. Within the 25 sensors 524 on each of the four sides, 17 sensors 524 are arranged to measure and simulate different positions of the average distribution of the top plate 42 of the raised floor 40, as shown in Figure 2. Also, as shown in Figure 4, different areas can be provided within the housing section S1 depending on the actual situation, and an appropriate number of sensors 524 can be installed accordingly. Naturally, the number of sensors 524 can be adjusted according to the dimensions of the top plate 42 of the raised floor 40 as measured or as needed.

[0050] The number of probes 526 is the same as the number of sensors 524, and each probe 526 is connected to a sensor 524, that is, the position of each probe 526 corresponds to the position of a sensor 524, and one end of each probe 526 protrudes from the detection surface S2 of the sensor mounting plate 522. These probes 526 are used to make contact with the top plate 42 of the raised floor 40, as shown in Figure 2, and the data acquired through these probes 526 is received by the corresponding sensors 524, which can receive this data and display it via a rear-end control platform (not shown), record the data from each probe 526, and thus determine where there are irregularities on the top plate 42 of the raised floor 40.

[0051] In one embodiment, the sensors 524 and their corresponding probes 526 are arranged in an array, and the probes 526 are arranged in a specific manner within one array, which may be in rows, columns, or other specified order. In a further embodiment, there are five sensors 524 and corresponding probes 526 on each of the four sides, with five probes on each of the four sides, and three rows are arranged within these probes located on the four sides, with six probes 526 in the first and third rows, respectively, and these six probes 526 are arranged in two rows, with a row of five probes 526 in the second row. For example, these probes 526 can detect data at different positions on the top plate 42 of the raised floor 40, calculate the flatness deviation of the entire top plate 42 of the raised floor 40, and the worst data obtained at a certain position can be taken as the flatness of the top plate 42, and the data is considered acceptable only if it is within a standard value, for example, the error of the standard value is ±0.2 mm, and anything exceeding ±0.2 mm is considered unacceptable.

[0052] These four plate surface zero-point positioning blocks 528 are provided at the four corners of the detection surface S2 of the sensor fixing plate 522. For convenience of explanation, the plate surface zero-point positioning blocks 528 located in different positions will be described as the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4. The first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 are located at the four corners of these probes 526. As shown in Figure 2, the dimensional range formed by the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, the fourth plate surface zero-point positioning block SP4, and these probes 526 can cover the top plate 42 of the raised floor 40.

[0053] Furthermore, the detection surface S2 of the sensor mounting plate 522 can be provided with four fixing parts B1, and these four fixing parts B1 are through holes for fixing members that can be used to connect the connecting column 5132 together, for example, as shown in Figure 1 or Figure 3.

[0054] Figure 7 is a perspective view of the positioning device and the lifting device for the raised floor according to the present invention. Figure 8 is a plan view of the positioning device and the lifting device for the raised floor according to the present invention. Figure 9 is a side view of the positioning device and the lifting device for the raised floor according to the present invention. Referring to Figures 2, 3, 7 to 9, the transport device 51 is used to transport the raised floor 40 to the measuring station LA2 along the transport direction LA, the positioning device 53 is used to position the side plate 44 of the raised floor 40, the position of the top plate 42 can be positioned relative to the measuring device 52, and the position of the top plate 42 can be made to correspond to the position of the detection surface S2 of the sensor fixing plate 522.

[0055] The positioning device 53 of the present invention is located at the measuring station LA2 and includes a first positioning member T1, a second positioning member T2, a third positioning member T31, a fourth positioning member T32, a fifth positioning member T4, a first push cylinder T11, and a second push cylinder T21. The first positioning member T1, the first push cylinder T11, the second positioning member T2, and the second push cylinder T21 are arranged along the transport direction LA, the first push cylinder T11 is connected to the first positioning member T1, and the second push cylinder T21 is connected to the second positioning member T2. At least one positioning member is installed on both sides of the transport direction LA. For example, in Figure 3, two positioning members, the third positioning member T31 and the fourth positioning member T32, are installed on the left side of the transport direction LA, and one positioning member, the fifth positioning member T4, is installed on the right side of the transport direction LA. The fifth positioning member T4 has the function of a push cylinder and can push the raised floor 40 against the third positioning member T31 and the fourth positioning member T32 for positioning.

[0056] The first positioning member T1, the second positioning member T2, the first push cylinder T11, and the second push cylinder T21 are all located between the two chain members 5144 of the conveying structure 514, the third positioning member T31 and the fourth positioning member T32 are located on one side of the two chain members 5144 of the conveying structure 514, and the fifth positioning member T4 is located on the other side of the two chain members 5144 of the conveying structure 514. That is, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 are located on opposite sides of the first positioning member T1 and the second positioning member T2.

[0057] Along the transport direction LA, the second positioning member T2 and the second push cylinder T21 connected thereto are, Adjacent to the standby station LA1, the first positioning member T1 and the first push cylinder T11 connected thereto are adjacent to the output station LA3. That is, when the raised floor 40 is transmitted to the measurement station LA2 by the chain member 5144, the raised floor 40 first passes through the second positioning member T2 and the second push cylinder T21 connected thereto, and then reaches the first positioning member T1 and the first push cylinder T11 connected thereto. Furthermore, in the process of the raised floor 40 being transmitted from the second positioning member T2 to the first positioning member T1, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 are located on opposite sides of the raised floor 40, and the area above the top plate 42 of the raised floor 40 is the measurement device 52.

[0058] Referring to Figures 3, 7, and 9, the installation heights of the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 are higher than the installation height of the chain member 5144, so that when the conveyed object (such as the raised platform 40 in Figure 2) passes over it, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 on both sides of the chain member 5144 can be positioned on both the left and right sides of the conveyed object (such as the raised platform 40 in Figure 2).

[0059] Since the installation height of the first push cylinder T11 and the second positioning member T2 is not higher than the installation height of the chain member 5144, the bottom side of the conveyed object (such as the raised platform 40 in Figure 2) does not come into contact with the first push cylinder T11 and the second positioning member T2 when it passes over it. However, since the first positioning member T1 is driven by the first push cylinder T11 and the second push cylinder T21 is driven by the second positioning member T2, the first positioning member T1 and the second positioning member T2 can protrude from the installation height of the chain member 5144. This allows the first positioning member T1 and the second push cylinder T21 to be positioned on both the front and rear sides of the conveyed object (such as the raised platform 40 in Figure 2), thereby positioning the raised platform 40. This prevents the first positioning member T1 and the second push cylinder T21 from protruding from the installation height of the chain member 5144, allowing the conveyed object (such as the raised platform 40 in Figure 2) to pass over the measuring station LA2.

[0060] Specifically, the first positioning member T1 includes a positioning plate 532, a rack 533, and a circular gear 534. As shown in Figure 9, one end of the rack 533 is connected to the first push cylinder T11, the other end of the rack 533 is connected to the circular gear 534, and the circular gear 534 is connected to the positioning plate 532. With this structure, the first push cylinder T11 pushes the rack 533, the rack 533 rotates the circular gear 534, and positions the positioning plate 532 to the positioning position or retracted position shown in Figure 9 (such as the positioning plate 532 shown by the dashed line in Figure 9). The installation height of the positioning plate 532 at the positioning position shown in Figure 3 is higher than the installation height of the chain member 5144, and it contacts one side of the conveyed object (such as the raised platform 40 in Figure 2), so that the raised platform 40 prevents forward movement and serves a positioning purpose. Conversely, in the case of the positioning plate 532 shown by the dashed line in Figure 9, the installation height of the positioning plate 532 shown by the dashed line in Figure 9 will not be higher than the installation height of the chain member 5144.

[0061] As shown in Figure 3, the installation position of the second push cylinder T21 is not higher than the installation height position of the chain member 5144. In one embodiment, as shown in Figure 9, the second push cylinder T21 can be moved up and down in the vertical direction LB by driving the second positioning member T2, so that as shown in Figure 3, the second push cylinder T21 can be positioned outside the origin position, the second push cylinder T21 can protrude from the set position of the chain member 5144, and the installation height of the second push cylinder T21 can be made higher than the installation height of the chain member 5144. In one embodiment, the second push cylinder T21 includes two contact members 538, and can be used for positioning by contacting the other side of the object to be conveyed (such as the raised floor 40 in Figure 2) with the installation height of the second push cylinder T21 higher than the installation height of the chain member 5144.

[0062] The third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 are positioned on both sides of the two chain members 5144 of the conveying structure 514. Taking the third positioning member T31 as an example, the third positioning member T31 includes a push cylinder 535 and a circular roller 536, the push cylinder 535 being connected to the circular roller 536, and the structural configuration of the fourth positioning member T32 and the fifth positioning member T4 is the same as that of the third positioning member T31, and also includes a push cylinder 535 and a circular roller 536. In this structural arrangement, the push cylinder 535 pushes the circular roller 536, moving the circular roller 536 toward the chain member 5144, and the circular roller 536 is brought into contact with the left and right sides of the conveyed object (such as the raised platform 40 in Figure 2) for positioning purposes.

[0063] Furthermore, as shown in Figure 1, the positioning mechanism is not only installed at the measurement station LA2, but in one embodiment, the positioning member 56 is also installed at the output station LA3 and can be used for positioning when moving the transported object (such as the raised platform 40 in Figure 2). The structure of the positioning member 56 may be the same as the structure of the third positioning member T31 described above.

[0064] Referring again to Figures 3 and 7-9, the floor lifting device 54 of the present invention is located at the measuring station LA2 and is used to raise and lower the floor 40 as shown in Figure 2. The floor lifting device 54 includes four lifting mechanisms 100 and a drive motor GM, the lifting mechanisms 100 being used to raise and lower the back side 46 of the floor 40 as shown in Figure 2. Of these, the bearing sheet 57 is provided above the support frame 513, the drive motor GM is fixed to the bearing sheet 57, and the drive motor GM drives the four lifting mechanisms 100 to move synchronously along the lifting direction LB, moving the floor 40 along the lifting direction LB as shown in Figure 2, moving the floor 40 away from the chain member 5144 shown in Figure 1 and closer to the measuring device 52. These four lifting mechanisms 100 each support the four corners of the floor 40 and can be raised and lowered smoothly. In another embodiment, the drive mechanism of each of the four lifting mechanisms 100 can achieve the objective of synchronously lifting the four lifting mechanisms 100 to a predetermined position by setting the torque.

[0065] Figure 10 is a perspective view of one embodiment of the lifting device for a raised floor according to the present invention. Referring to Figure 10, the lifting device 54 for a raised floor according to the present invention includes four lifting mechanisms 100, a drive motor GM, a belt 542, two first support plates 544, and two second support plates 545. The ends of the two first support plates 544 are each connected to two second support plates 545, and the connection of the two first support plates 544 and the two second support plates 545 forms a rectangular frame, which performs linear lifting motion in synchronization with four screws G13, and drives the contact block D12 of the lifting device 54 for the raised floor in synchronization with the screws G13 of the four lifting mechanisms 100, and contacts the four corners of the raised floor in synchronization. The positions of these four lifting mechanisms 100 can correspond to the positions of the first, second, third, and fourth zero-point positioning blocks SP1, SP2, SP3, and SP4 of the measuring device 52, as shown in Figure 5. These four lifting mechanisms 100 move the raised floor 40 synchronously along the lifting direction LB and make contact with the first, second, third, and fourth zero-point positioning blocks SP1, SP2, SP3, and SP4.

[0066] The drive motor GM is located between the two lifting mechanisms 100. The belt 542 is wrapped around the transmission wheel 151 and the drive motor GM of the four lifting mechanisms 100, forming a synchronous drive mechanism. The contact blocks D12 of these four lifting mechanisms 100 correspond to the positions of the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 in the measuring device 52, as shown in Figure 5.

[0067] In this way, the drive motor GM drives the rotation of the belt 542, which in turn drives the transmission wheels 151 of the four lifting mechanisms 100, enabling the contact blocks D12 of the four lifting mechanisms 100 to perform lifting movements. Since the four lifting mechanisms 100 are driven by the same drive source (drive motor GM) and transmission structure (belt 542), they can perform lifting movements synchronously, raising and lowering the contact blocks D12 to predetermined positions and avoiding positional differences in the lifting movements of the four lifting mechanisms 100.

[0068] In one embodiment, the lifting mechanism 100 may include two independent lifting modes: high-speed lifting modules G1, G2, G3, G4 and low-speed lifting modules D1, D2, D3, D4. In addition to the synchronous execution of the lifting operations of the four lifting mechanisms 100 described above, the high-speed lifting modules G1, G2, G3, G4 allow the heights of the four lifting mechanisms 100 to be raised synchronously and quickly. Furthermore, by supplementing the high-speed lifting modules G1, G2, G3, G4 with the low-speed lifting modules D1, D2, D3, D4, the close contact of the raised floor 40 with the four corners can be enhanced.

[0069] Figure 11 is an explanatory diagram of one embodiment of the lifting position of the lifting device for a raised floor according to the present invention, illustrating that the lifting device 54 raises the height of the raised floor 40 at the lifting position P1, where the lifting position P1 includes the lifting positions P11 of the high-speed lifting modules G1, G2, G3, and G4 and the lifting positions P12 of the low-speed lifting modules D1, D2, D3, and D4. Figure 12 is an explanatory diagram of one embodiment of the origin position of the lifting device for a raised floor according to the present invention, illustrating the origin position P2 before the raised floor 40 is lifted by the lifting device 54, where the origin position P2 includes the origin positions P21 of the high-speed lifting modules G1, G2, G3, and G4 and the origin positions P22 of the low-speed lifting modules D1, D2, D3, and D4.

[0070] Referring to Figures 11 and 12, each of the low-speed lifting modules D1, D2, D3, and D4 of the present invention is connected and positioned above the corresponding high-speed lifting modules G1, G2, G3, and G4 of the lifting mechanism 100. The high-speed lifting module G1 includes a T-nut connector G11, a connecting flange G12, and screws G13, with one end of each of these four screws G13 fixed to both ends of the first support plate 544. In this way, the aforementioned belt 542 drives the rotation of the transmission wheel 151, thereby synchronously rotating the transmission wheel connector 152 within the transmission wheel 151 and the T-nut 153 connected thereto (as shown in Figure 15A). At this time, since the first support plate 544 and the second support plate 545 at the bottom of the four screws G13 are fixed ends, the screws G13 cannot rotate, and the transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto in synchronous motion. The T-shaped nut 153 drives the screws G13 to perform vertical linear motion, and the lifting position P11 shown in Figure 11 drives the low-speed lifting modules D1, D2, D3, D4 and the contact block D12 connected thereto to raise their height positions, and further raises the height position of the raised floor 40. The transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto in synchronous motion, and the T-shaped nut 153 drives the screws G13 to perform vertical linear motion, quickly driving the linear upward movement of the screws G13, that is, converting the rotational motion of the T-shaped nut 153 into the linear motion of the screws G13, and quickly achieving the objective of raising the position. By combining the aforementioned method of simultaneously driving the four lifting mechanisms 100 with a single power source (drive motor GM), the raised floor 40 can be quickly raised to a predetermined height in synchronous motion, avoiding positional differences due to differences in the lifting positions of the four lifting mechanisms 100, and the four corners of the raised floor 40 can be stably raised by the four lifting mechanisms 100, avoiding differences in the height of the four corners of the raised floor 40 and preventing the raised floor 40 from sliding down during the lifting process.

[0071] Conversely, as shown in Figure 12, the aforementioned transmission wheel 151 can be used to synchronously drive the transmission wheel connector 152 and the T-shaped nut 153 connected thereto to rotate in opposite directions, thereby returning the extended end 142 of the screw G13 and the connecting flange G12 connected thereto to the origin position P21 shown in Figure 12, and returning the low-speed lifting modules D1, D2, D3, D4 and the contact block D12 connected thereto to their respective height positions.

[0072] In addition to the high-speed lifting modules G1, G2, G3, and G4 described above, the low-speed lifting modules D1, D2, D3, and D4 of the present invention, with reference to Figures 11 and 12, include a contact block D12 and a cylinder power source D11. The cylinder power source D11 is connected to the contact block D12, the gasket 111 is fixed to the contact block D12, and the other end of the cylinder power source D11 is connected to the high-speed lifting modules G1, G2, G3, and G4. The function of the low-speed lifting modules D1, D2, D3, and D4 of the present invention is to complement the high-speed lifting modules G1, G2, G3, and G4. However, due to various factors such as gaps in the combination of components, tolerances during processing of the thickness of the four corners of the raised floor 40, and total errors caused by measuring tools, it is not possible to perfectly align the four corner surfaces of the raised floor 40 with the positions of the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 of the measuring device 52. By utilizing the pneumatic controllability of the cylinder power source D11, the cylinder power source D11 moves the contact block D12 to adjust the height position of the raised floor 40.

[0073] The cylinder output utilizes pneumatic adjustment control according to the weight of the raised floor 40 and a finite position-free function of the cylinder, enabling the raised floor 40 to be lifted with the most appropriate force. The four corners of the raised floor 40 are perfectly aligned with the positions of the first, second, third, and fourth zero-point positioning blocks SP1, SP2, SP3, and SP4 of the measuring device 52, ensuring the effectiveness and accuracy of the flatness measurement.

[0074] Before measuring the flatness of the raised floor, a zero correction operation is first performed on the probe 526 of the measuring device 52 in order to return the position of the probe 526 of the measuring device 52 to the origin position. The following describes the zero correction operation of the automatic flatness measurement of the raised floor according to the present invention. First, a high-precision block gauge is selected, whose dimensions are, for example, 600 mm × 600 mm × 60 mm, and in one embodiment, the structure and dimensions of the high-precision block gauge are the same as those of the raised floor 40 shown in Figure 2. As shown in Figure 1, the high-precision block gauge is placed in the standby station LA1, and the high-precision block gauge is moved to the measuring station LA2 via the chain member 5144 of the transport device 51, so that the high-precision block gauge is positioned below the measuring device 52.

[0075] Next, as shown in Figure 3, when the front side of the high-precision block gauge comes into contact with the positioning plate 532 of the first positioning member T1, the chain member 5144 stops transporting the high-precision block gauge. Next, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4, located on both sides of the chain member 5144, begin to move. Of these, the circular rollers 536 of the third positioning member T31 and the fourth positioning member T32 extend and move toward the direction of the high-precision gauge block, allowing them to be positioned to the left of the high-precision gauge block, and the circular roller 536 of the fifth positioning member T4 extends and moves toward the right side of the high-precision gauge block (i.e., toward the third positioning member T31 and the fourth positioning member T32), allowing the high-precision gauge block to be pushed toward the third positioning member T31 and the fourth positioning member T32. Thus, the high-precision gauge block can be brought closer to the third positioning member T31 and the fourth positioning member T32, that is, the left and right sides of the high-precision gauge block are positioned by the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4. Finally, the second positioning member T2 drives the second push cylinder T21 to move, causing the second push cylinder T21 to protrude from the installation position of the chain member 5144, moving the second push cylinder T21 toward the high-precision block gauge, i.e., toward the first positioning member T1, and contacting the high-precision block gauge via the contact member 538 of the second push cylinder T21, pushing the high-precision block gauge toward the positioning plate 532 of the first positioning member T1. In this way, all four sides of the high-precision block gauge are positioned by the first positioning member T1, the second push cylinder T21, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4 of the positioning device 53, and the positioning of the high-precision block gauge is completed.

[0076] Next, as shown in Figure 9, the first push cylinder T11 pushes the rack 533, causing the circular gear 534 to rotate on the rack 533 and rotating the positioning plate 532 from the positioning position shown in Figure 9 to the retracted position (positioning plate 532 shown by the dashed line in Figure 9). Meanwhile, the second positioning member T2 returns the second push cylinder T21 to its origin position, that is, the installation height of the second positioning member T2 does not become higher than the installation height of the chain member 5144. In addition, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4, located on both sides of the chain member 5144, begin to move, return to their origin positions, and move away from the high-precision block gauges, completing the return operation of all positioning devices 53.

[0077] Next, as shown in Figure 10, the drive motor GM is activated, causing the belt 542 to rotate. The belt 542 drives the transmission wheels 151 of each lifting mechanism 100, which in turn rapidly raise the heights of the four lifting mechanisms 100 in sync using the high-speed lifting modules G1, G2, G3, and G4 of each lifting mechanism 100. These four lifting mechanisms 100 then lift the high-precision gauge block to a predetermined height.

[0078] After the high-speed lifting modules G1, G2, G3, and G4 lift the high-precision gauge blocks to a predetermined height, the low-speed lifting modules D1, D2, D3, and D4 then lift the upper surface of the high-precision gauge blocks to the positions of the first, second, third, and fourth zero-point positioning blocks SP1, SP2, SP3, and SP4 of the measuring device 52, bringing them into contact with each other. At this time, the first, second, third, and fourth zero-point positioning blocks SP1, SP2, SP3, and SP4 are located at the four corners of the probes 526. Therefore, when the upper surface of the high-precision gauge block comes into contact with the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 of the measuring device 52, the probe 526 of the measuring device 52 also comes into contact with the upper surface of the high-precision gauge block.

[0079] Finally, after confirming that all probes 526 have made contact with the upper surface of the high-precision gauge block, the data acquired through these probes 526 is received by the corresponding sensors 524, which can receive and display this data via the rear-end control platform (such as the BCS display), and all data acquired by the probes 526 is reset to zero, completing the zero correction operation for the automatic flatness measurement of the raised floor.

[0080] Next, the low-speed lifting modules D1, D2, D3, D4 and the high-speed lifting modules G1, G2, G3, G4 are returned to their original positions, and the high-precision gauge blocks are again positioned on the two chain members 5144 of the transport structure 514. Then, the high-precision gauge blocks are moved from the measuring station LA2 to the output station LA3 via the chain members 5144. After that, the rack 533 is pushed via the first push cylinder T11, causing the circular gear 534 on the rack 533 to rotate, and the positioning plate 532 is rotated from the retracted position shown in Figure 9 to the positioning position (such as the positioning plate 532 shown by the solid line in Figure 9), and then subjected to the next correction operation.

[0081] After the zero correction operation of the automatic flatness measurement of the raised floor described above, the position data of the probe 526 in the measuring device 52 is set to zero and used as the reference for the flatness of the top plate of the subsequent raised floor. The automatic measurement operation of the floor surface flatness of the raised floor of the present invention will be explained below as an example. First, as shown in Figure 2, the raised floor 40 is placed in the waiting station LA1 as shown in Figure 1, and the chain member 5144 of the transport device 51 moves the raised floor 40 to the measuring station LA2 so that the raised floor 40 is positioned below the measuring device 52 and the top plate 42 faces the detection surface S2 of the measuring device 52, and these probes 526 are used to face and contact the top plate 42 of the raised floor 40 shown in Figure 2.

[0082] Next, as shown in Figure 3, when the front side of the raised platform 40 contacts the positioning plate 532 on the first positioning member T1, the chain member 5144 stops transporting the raised platform 40. Then, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4, located on either side of the chain member 5144, begin to move. Of these, the circular rollers 536 of the third positioning member T31 and the fourth positioning member T32 extend and move toward both sides of the raised floor 40, positioning the left side of the raised floor 40, while the circular roller 536 of the fifth positioning member T4 extends and moves toward the right side of the raised floor 40 (i.e., toward the third positioning member T31 and the fourth positioning member T32), pushing the raised floor 40 toward the third positioning member T31 and the fourth positioning member T32, thereby bringing the raised floor 40 closer to the third positioning member T31 and the fourth positioning member T32, that is, by the third positioning member T31, the fourth positioning member T32 and the fifth positioning member T4 The left and right sides of the raised floor 40 are positioned. Finally, the second positioning member T2 drives the second push cylinder T21 to move, causing the second push cylinder T21 to protrude from the installation position of the chain member 5144, moving the second push cylinder T21 toward the raised floor 40, that is, toward the first positioning member T1, and making contact with the raised floor 40 via the contact member 538 of the second push cylinder T21, pushing the raised floor 40 toward the positioning plate 532 in the first positioning member T1, and in this way the four sides of the raised floor 40 are positioned by the first positioning member T1, the second push cylinder T21, the third positioning member T31, the fourth positioning member T32 and the fifth positioning member T4 in the positioning device 53, and the positioning of the raised floor 40 is completed.

[0083] Next, as shown in Figure 9, the first push cylinder T11 pushes the rack 533, causing the circular gear 534 to rotate on the rack 533 and rotating the positioning plate 532 from the positioning position shown in Figure 9 to the retracted position (positioning plate 532 shown by the dashed line in Figure 9). Meanwhile, the second positioning member T2 returns the second push cylinder T21 to its origin position, that is, the installation height position of the second positioning member T2 does not become higher than the installation height position of the chain member 5144. In addition, the third positioning member T31, the fourth positioning member T32, and the fifth positioning member T4, located on both sides of the chain member 5144, begin to move, return to their origin positions, and move away from the raised floor 40, completing the return operation of the entire positioning device 53.

[0084] Next, as shown in Figures 10 and 11, the drive motor GM is activated, which rotates the belt 542, which drives the transmission wheels 151 of each lifting mechanism 100, and the high-speed lifting modules G1, G2, G3, and G4 of each lifting mechanism 100 rapidly raise the heights of these four lifting mechanisms 100 in sync, allowing the raised floor 40 to be lifted to a predetermined height by these four lifting mechanisms 100.

[0085] After the raised floor 40 is lifted to a predetermined height by the high-speed lifting modules G1, G2, G3, and G4, the lifting operation of the low-speed lifting modules D1, D2, D3, and D4 raises the top plate 42 of the raised floor 40 until it contacts the positions of the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 of the measuring device 52. At this time, the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 are located at the four corners of their respective probes 526. Therefore, when the top plate 42 of the raised floor 40 comes into contact with the first plate surface zero-point positioning block SP1, the second plate surface zero-point positioning block SP2, the third plate surface zero-point positioning block SP3, and the fourth plate surface zero-point positioning block SP4 of the measuring device 52, the probe 526 of the measuring device 52 comes into contact with the top plate 42 of the raised floor 40.

[0086] Finally, the data acquired through these probes 526 is received by the corresponding sensors 524, which receive this data and display it via the rear-end control platform (such as the BCS display) to complete the automatic measurement of the flatness of the raised floor surface, calculate the flatness deviation of the entire top plate 42 of the raised floor 40, and the worst data acquired at a certain location can be taken as the flatness of this top plate 42.

[0087] Next, the low-speed lifting modules D1, D2, D3, D4 and the high-speed lifting modules G1, G2, G3, G4 are returned to their original positions, and the raised platform 40 is again positioned on the two chain members 5144 of the transport structure 514. Then the raised platform 40 is transported from the measurement station LA2 to the output station LA3 via the chain members 5144. Next, the rack 533 is pushed via the first push cylinder T11, causing the circular gear 534 on the rack 533 to rotate, and the positioning plate 532 is rotated from the retracted position shown in Figure 9 to the positioning position (such as the positioning plate 532 shown by the solid line in Figure 9) to receive the next measurement operation.

[0088] Figure 13A is an explanatory diagram of one embodiment of the lifting position of the lifting mechanism according to the present invention. Figure 13B is an explanatory diagram of one embodiment of the origin position of the lifting mechanism according to the present invention. Figure 14A is an exploded view of the corresponding members in a cross-section of the lifting mechanism according to the present invention. Figure 14B is an exploded view of the lower connecting flange and screw according to the present invention. Figure 15A is a cross-sectional view of one embodiment of the raised position of the lifting mechanism according to the present invention. Figure 15B is a cross-sectional view of one embodiment of the origin position of the lifting mechanism according to the present invention. Referring to Figures 13A to 15B, the lifting position P1 of the lifting mechanism 100 in Figures 13A and 15A corresponds to the lifting mechanism 100 in Figure 11, and the lifting position P1 includes the lifting positions P11 of the high-speed lifting modules G1, G2, G3, and G4 and the lifting positions P12 of the low-speed lifting modules D1, D2, D3, and D4. The origin position P2 in Figures 13B and 15B corresponds to the lifting mechanism 100 in Figure 12, and the origin position P2 includes the origin position P21 of the high-speed lifting modules G1, G2, G3, and G4, and the origin position P22 of the low-speed lifting modules D1, D2, D3, and D4.

[0089] The lifting mechanism 100 includes a high-speed lifting module G1, a low-speed lifting module D1, and a T-type connector E1. The lifting mechanism 100 includes two independent lifting modes: the high-speed lifting module G1 and the low-speed lifting modules D1, D2, D3, and D4. The high-speed lifting modules G1, G2, G3, and G4 can be quickly raised to a predetermined height, while the low-speed lifting modules D1, D2, D3, and D4 are fixed above the high-speed lifting modules G1, G2, G3, and G4. The low-speed lifting modules D1, D2, D3, and D4 and the high-speed lifting modules G1, G2, G3, and G4 move up and down in sync. The high-speed lifting module G1 includes a T-type nut connector G11, a connecting flange G12, and a screw G13. The low-speed lifting module D1 includes a cylinder power source D11, a contact block D12, and a T-type connector E1.

[0090] The T-type nut connector G11 includes a transmission wheel 151, a transmission wheel connector 152, a T-type nut 153, a bearing seat 154, at least one bearing 155, a nut 156, a retaining structure 157, a C-type mating ring 158, and two deep groove bearings 159. The number of bearings 155 can be adjusted according to the structural arrangement.

[0091] A transmission wheel connector 152 is installed inside the transmission wheel 151, and one side of a T-nut 153 is connected to the transmission wheel connector 152. The T-nut 153 is fixed together with the transmission wheel 151 by the transmission wheel connector 152 and can rotate synchronously.

[0092] In one embodiment, a T-shaped nut 153 is housed within a bearing seat 154. The T-shaped nut 153 has a long through-hole, and its upper end has a male thread. The lower end of the T-shaped nut 153 is connected to and fixed with the transmission wheel 151, allowing them to rotate as a single unit. For example, when assembling the T-shaped nut connector G11, first the shaft portion of the transmission wheel connector 152 is fitted into the central hole of the transmission wheel 151, and the shaft portion of the T-shaped nut 153 is fitted upward into the central hole of the bearing seat 154. Then, at least one fixing screw SC is used to pass through the through-hole H1 of the transmission wheel 151, the through-hole H2 of the transmission wheel connector 152, and the through-hole H3 of the T-shaped nut 153 in sequence, thereby fixing the transmission wheel 151, transmission wheel connector 152, and T-shaped nut 153 as a single unit, and connecting and fixing the transmission wheel 151 and the T-shaped nut 153 as a single unit.

[0093] The bearing 155 is housed within the bearing seat 154, and the bearing 155 is positioned between the T-nut 153 and the bearing seat 154. The nut 156 is fixed to the outer teeth of the upper end of the T-nut 153, fixing the position of the bearing 155.

[0094] The C-shaped fitting ring 158, the two deep groove bearings 159, and the retaining structure 157 are positioned on the outer circumference of the T-shaped nut 153, and the deep groove bearings 159 are positioned at the upper and lower ends of the retaining structure 157, with the retaining structure 157 fixing the positions of the two deep groove bearings 159. The C-shaped fitting ring (C-Ring Clip) 158, also called an elastic fitting ring (Circlip) or retaining ring, is an elastic fastener used to fix a part or bearing to a shaft or hole. It usually has a C-shaped or nearly circular structure with openings at both ends, and after installation, it can firmly fix the part in place by elastic force. Taking this embodiment as an example, the C-shaped fitting ring 158 is positioned between one deep groove bearing 159 and bearing 155, reinforcing and fixing the position of bearing 155.

[0095] The Deep Groove Ball Bearing 159 is a roller bearing characterized by having deep, arc-shaped grooves in the raceways of its inner and outer rings, allowing it to withstand radial loads and a constant axial load.

[0096] The connecting flange G12 includes a lower connecting flange 161 and an upper connecting flange 162 connected to the lower connecting flange 161, the upper connecting flange 162 being positioned above the lower connecting flange 161. In one embodiment, bolts (not shown) are used to fasten the upper connecting flange 162 and the lower connecting flange 161 together through a through hole H4.

[0097] The upper end of screw G13 is fixed to the lower connecting flange 161, and the lower end of screw G13 passes sequentially through nut 156, T-nut 153, bearing 155, transmission wheel connector 152, and transmission wheel 151. A first bolt 145 and bolt head 146 are installed above the T-nut connector G11. In one embodiment, screw G13 includes an extended end 142, the upper end of screw G13 is connected to the lower end of the first bolt 145, the upper end of the first bolt 145 is the bolt head 146, the first bolt 145 is inserted into the countersink hole 161A of the lower connecting flange 161 and fixed to the screw hole at the upper end of screw G13, fixing screw G13 and the lower connecting flange 161 together, and the bolt head 146 is fixedly connected to the countersink hole 161A of the lower connecting flange 161. As can be seen from this, the first bolt 145 is fixed to the lower connecting flange 161 using the bolt head 146 at the upper end of the first bolt 145, and the extended end 142 of the screw G13 is fixed to the lower connecting flange 161 by the first bolt 145. The first bolt 145 and its bolt head 146 may be integrally molded with the bolt, and other fixing members may be used to replace the first bolt 145 and its bolt head 146. In this invention, the first bolt 145 is used for fixing.

[0098] In one embodiment, as shown in Figure 14B, a countersunk hole 161A is provided within the lower connecting flange 161, and the first bolt 145 passes through and is located in the countersunk hole 161A. The countersunk hole 161A is a hole machined into the material surface and has a single conical expansion hole at its opening for accommodating the head of a countersunk screw (such as the first bolt 145). The head of the first bolt 145 can be flush with the surface of the lower connecting flange 161 or slightly lower than the surface. The design of the countersunk hole 161A mainly emphasizes aesthetics and functionality. For example, the head of the first bolt 145 does not protrude and affect the flatness and aesthetics of the lower connecting flange 161. The lower connecting flange 161, with its flattened upper surface, can be coupled and fixed with the upper connecting flange 162.

[0099] The screw G13 is sequentially provided with a nut 156, a T-type nut 153, and a transmission wheel connector 152 on the transmission wheel 151. The aforementioned T-type nut connector G11, connecting flange G12, and screw G13 constitute the high-speed lifting module G1. The low-speed lifting module D1 includes a cylinder power source D11 and a contact block D12, the contact block D12 being connected to the cylinder power source D11.

[0100] One end of the T-type connector E1 is connected to the upper connecting flange 162, and the other end of the T-type connector E1 is provided with a fixing base 148. The upper connecting flange 162 and the fixing base 148 at both ends of the T-type connector E1 are connected and fixed to the high-speed lifting module G1 and the low-speed lifting module D1, respectively. In other words, one end of the T-type connector E1 is connected and fixed to the high-speed lifting module G1 via the upper connecting flange 162, and the other end of the T-type connector E1 is connected and fixed to the low-speed lifting module D1 via the fixing base 148.

[0101] One end of the T-type connector E1 is mounted on the fixed base 148, and the other end of the T-type connector E1 is connected to the upper connecting flange 162. The second bolt 143 is connected to the fixed base 148, and the upper end of the T-type connector E1 is the fixed base 148. The lower end of the T-type connector E1 is the upper connecting flange 162, and the upper end of the T-type connector E1 is connected and fixed to the bottom of the cylinder power source D11 via the second bolt 143 and the fixed base 148. The method of fixing the second bolt 143 and the aforementioned first bolt 145 is the same; that is, the fixed base 148 of the T-type connector E1 is passed through the bottom of the cylinder power source D11 using the second bolt 143 and fixed to the screw hole of the fixed base 148, thereby connecting and fixing the cylinder power source D11 to the fixed base 148. As can be seen from this, the bottom of the cylinder power source D11 is connected and fixed to the fixing base 148 at the upper end of the T-type connector E1 via the second bolt 143, and the upper connecting flanges 162 and fixing bases 148 at both ends of the T-type connector E1 are connected and fixed to the high-speed lifting module G1 and the low-speed lifting module D1, respectively. The second bolt 143 may be replaced with other fixing members, but the present invention employs the second bolt 143 for fixing.

[0102] The rotation of the transmission wheel 151 is driven, causing the transmission wheel connector 152 inside the transmission wheel 151 and the T-shaped nut 153 connected thereto to rotate synchronously. The T-shaped nut 153 is fixed to the transmission wheel 151, and as the T-shaped nut 153 rotates, the screw hole 149 at the bottom end of the screw G13 can be fixed to both ends of the first support plate 544 using screws (not shown) (as shown in Figures 10 to 12), making the bottom end of the screw G13 a fixed end and preventing the screw G13 from rotating. The T-shaped nut 153 drives the screw G13 to move up and down linearly. The up and down linear motion (or vertical motion) of the screw G13 refers to the movement of the screw G13 along a straight line in the vertical direction. The direction of motion of the screw G13 is up and down, and the motion is along a straight line, driving the low-speed lifting module D1 and the contact block D12 connected thereto to raise its height position, as shown in the lifting position P11 in Figure 13A or Figure 15A. The transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto, quickly driving the linear upward movement of the screw G13, that is, converting rotational motion into linear motion and quickly reaching the raised position.

[0103] Conversely, as shown in Figure 13B or Figure 15B, the transmission wheel 151 can rotate in the opposite direction to the transmission wheel connector 152 and the T-nut 153 connected thereto, returning the extended end 142 of the screw G13 and the connecting flange G12 pivotally attached thereto to the origin position P21 as shown in Figure 13B or Figure 15B, and returning or lowering the low-speed lifting module D1 and the contact block D12 connected thereto to their height position.

[0104] The cylinder power source D11 includes a cylinder body 132, a piston 134, at least one through hole 135, at least one air intake / exhaust hole 136, and a plurality of fixed rods 137. The piston 134 can move within the cylinder body 132 and includes a protruding end 134A and an upper part 134B. The protruding end 134A is connected to the upper part 134B, which is connected and fixed to the bottom of the contact block D12. The cylinder power source D11 can raise and lower the contact block D12 at a low speed to adjust its height. One end of the fixed rod 137 passes through the cylinder body 132, and the other end of the fixed rod 137 is connected to the upper part 134B. The piston 134 is able to lift the contact block D12 evenly and in a balanced manner using the plurality of fixed rods 137, causing it to move up and down at a low speed, and the fixed rods 137 can be linked to the contact block D12.

[0105] In one embodiment, the cylinder body 132 is fixed to the bottom of the cylinder body 132 by passing through a through hole 135 using bolts (not shown), and at least one air intake / exhaust hole 136 is provided in the cylinder body 132.

[0106] The aforementioned cylinder power source D11, contact block D12, and T-type connector E1 constitute a low-speed lifting module D1. By utilizing the pneumatic controllability of the cylinder power source D11, the cylinder power source D11 moves the contact block D12, allowing the piston 134 to move within the cylinder body 132. As a result, the protruding end 134A of the piston 134 and the upper part 134B connected thereto slide the contact block D12 on the fixed rod 137, changing its height position to raise it to the lifting position P12 as shown in Figure 13A or Figure 15A, or the protruding end 134A of the piston 134 drives the contact block D12, changing its height position to return it to or lower it to the origin position P22 as shown in Figure 13B or Figure 15B.

[0107] In one embodiment, the lifting mechanism 100 includes a gasket 111, which is mounted on a contact block D12. The contact block D12 is secured to the gasket 111 by bolts (not shown) passing through holes 111A.

[0108] As can be seen from this, the lifting mechanism 100 includes two independent lifting modes: a high-speed lifting module G1 and a low-speed lifting module D1. The function of the low-speed lifting module D1 of the present invention complements the high-speed lifting module G1 and can accommodate gaps in combinations between members or tolerances of measuring tools. The cylinder output uses pneumatic adjustment control according to the weight of the object being lifted, and the cylinder has no finite position restriction function, allowing the object to be lifted with the most appropriate force and to be perfectly joined to the surface of another object.

[0109] In summary, the present invention can measure the flatness of the raised floor during the transmission process, improve measurement accuracy, reduce errors or structural problems that occur after assembly, and improve overall process efficiency.

[0110] Furthermore, the number of probes and sensors in this invention can be adjusted according to the actual dimensions or requirements of the raised floor and top plate to be measured, thereby improving the accuracy of measuring flatness.

[0111] Furthermore, the present invention uses a plate surface zero-point positioning block to fix and confirm the positions of the four corners of the measuring device and the top plate of the raised floor, thereby ensuring the relative position of the probe and the top plate.

[0112] Furthermore, in the transmission process of the present invention, the positioning device positions all four sides of the raised floor and secures the relative position between the raised floor and the measuring device, thereby ensuring the accuracy of subsequent measurements.

[0113] Furthermore, the present invention configures the four lifting mechanisms installed on the raised floor as a synchronous activation mechanism using a lifting device for the raised floor, allowing the lifting operation to be performed synchronously, raising and lowering the raised floor to a predetermined position, and avoiding positional differences in the lifting operation of the four lifting mechanisms.

[0114] Furthermore, the lifting mechanism of the present invention has two types of independent high-speed lifting modules and low-speed lifting modules. The high-speed lifting module can quickly raise the object to a predetermined height, and the pneumatic control of the low-speed lifting module can correct any errors in the joint.

[0115] Although the present invention has been disclosed by embodiments as described above, this does not limit the invention, and those skilled in the art can make some modifications and alterations without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be based on the claims defined below. [Explanation of symbols]
