Description

Technical Field

[0001] This utility model belongs to the technical field of liquefied natural gas (LNG) insulation box production equipment, specifically relating to a T-shaped plate positioning and nailing device. Background Technology

[0002] With the accelerated energy transition, global liquefied natural gas (LNG) trade volume is projected to grow from 250 million tons in 2010 to 450 million tons in 2024, driving a continuous increase in LNG carrier orders. The cargo containment system is a core component of the LNG carrier's cargo tanks, responsible for the safe storage of LNG at ultra-low temperatures of -163°C. Key components of the cargo containment system include an insulating box that provides thermal insulation. Within the insulating box, a T-shaped panel is used as a separator, typically formed by nailing together an IS panel (steel wire mesh sandwich panel) and a No. 9 panel (9mm thick sandwich wood panel). With technological advancements, increasingly higher requirements are being placed on this T-shaped panel.

[0003] Taking the GTT NO96 Super+ liquid cargo containment system as an example, this system reduces the daily evaporation rate (BOR) from 0.10% V / d in NO96L03+ to 0.085% V / d. Its core improvement is the replacement of plywood boxes with reinforced polyurethane foam (R-PUF) and the insertion of glass wool joints between adjacent foam boards to optimize thermal performance. This material replacement places higher demands on assembly precision: the gap between the IS board and the No. 9 board needs to be controlled within 2-5mm, and the edge bevel angle deviation ≤±1°; otherwise, it will lead to a cold bridge effect, directly affecting the BOR index.

[0004] However, the IS plate and the No. 9 plate will expand and contract due to thermal changes at -163℃, making it difficult to control the deformation (≤±1.5mm) during manual assembly. Tests conducted by relevant shipyards show that the gap deviation of manually assembled insulation boxes can reach ±3mm after low-temperature testing, far exceeding the design requirements, while automated assembly lines control the deviation within ±0.5mm through a dynamic compensation mechanism.

[0005] Based on current process requirements, considering the variables of starting nail position and nail spacing, there are four different sizes: 23, 26, 27, and 28 mm. If manual nailing is used, multiple nail gun positioning modules need to be manually adjusted when processing boards of different sizes. An error in adjusting any one of these modules will render the entire board unusable. Furthermore, the nail position requirements are high, thus the positioning modules also need high precision, resulting in relatively high manufacturing costs. Additionally, if subsequent process requirements change, the positioning modules will need to be continuously updated.

[0006] Therefore, in order to produce this T-shaped board more reliably, conveniently and efficiently, and to adapt to changes in subsequent process requirements, a new type of positioning and nailing equipment is needed. Utility Model Content

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the T-shaped board nailing device of this utility model in detail with reference to the embodiments and accompanying drawings.

[0030] Figure 1 This is a perspective view of this embodiment.

[0031] like Figure 4As shown, the T-shaped board 20 is composed of an IS board 21 and a No. 9 board 22. The surfaces of the two boards are perpendicular to each other. One end of the No. 9 board 22 is placed in the middle of one surface of the IS board 21. The two boards are fixed together by driving in multiple nails to form the T-shaped board 20.

[0032] T-shaped sheet 20 comes in various models. Among the different models of T-shaped sheet 20, the length of IS sheet 21 and No. 9 sheet 22 can be 600mm-1450mm, and the lengths of both are the same. The width of IS sheet 21 and No. 9 sheet 22 can be 165mm-270mm, and the widths of both can be different.

[0033] like Figures 1 to 3 As shown, the T-shaped sheet positioning and nailing device 10 for preparing this T-shaped sheet 20 includes a frame 11, a length positioning mechanism 12, a width positioning mechanism 13, a height positioning mechanism 14, and a nailing mechanism 15. The length positioning mechanism 12 positions the IS sheet 21 and the No. 9 sheet 22 in the length direction. The width positioning mechanism 13 positions the IS sheet 21 in the width direction. The height positioning mechanism 14 positions the No. 9 sheet 22 in the height direction (the height direction during processing and the width direction of the No. 9 sheet 22 itself). The nailing mechanism 15 nails the IS sheet 21 and the No. 9 sheet 22, which are positioned in both the length and width directions, thereby fixing them into a T-shaped sheet 20.

[0034] The frame 11 consists of a horizontal plate section 111, a bottom beam 112, and multiple uprights. The horizontal plate section 111 is composed of multiple square rods and two horizontal rectangular plates, and the upper surface of the horizontal plate section 111 is a worktable. A strip-shaped hole 111a extending along its length and penetrating along its thickness is provided on the horizontal plate section 111, and the width of the strip-shaped hole 111a is greater than the thickness of the plate 22.

[0035] The bottom beam 112 is horizontally fixed below the horizontal plate 111.

[0036] Four columns 113 are used to support the horizontal plate 111. Among them, the two columns 113 on one side of the width direction of the horizontal plate 111 are longer and their upper ends extend to the top of the horizontal plate 111.

[0037] The length positioning mechanism 12 includes a fixed stop 121 and a length clamping assembly 122.

[0038] The fixing block 121 is T-shaped and fixed to the horizontal plate 111. The upper end of the T-shape is positioned above the horizontal plate 111 and fixed to it by multiple fasteners (screws). The lower end of the T-shape passes through the strip hole 111a and extends below the horizontal plate 111. In this embodiment, the fixing block 121 is a hardened metal block with a thickness of 10mm to 20mm, preferably 15mm.

[0039] The length-direction clamping assembly 122 includes a mounting plate 1221, a clamping cylinder 1222 (length-direction clamping cylinder), and a T-shaped pressure plate 1223.

[0040] Mounting plate 1221 is fixed to the horizontal plate portion 111. A clamping cylinder 1222 is horizontally fixed to mounting plate 1221, with its piston rod facing the center of the horizontal plate portion and its direction aligned with the length direction of the horizontal plate portion 111. A T-shaped pressure plate 1223, in the shape of a T, is mounted on the piston rod, its surface direction perpendicular to the surface direction of the horizontal plate portion 111. The upper end of the T-shape of the pressure plate 1223 is positioned above the horizontal plate portion 111, and the lower end of the T-shape passes through the strip hole 111a and extends below the horizontal plate portion 111. That is, the position of the T-shaped pressure plate 1223 corresponds horizontally to the position of the fixing block 121.

[0041] In this embodiment, the clamping cylinder 1222 is model SC-40×200. The IS plate 21 and the No. 9 plate 22 are positioned in the length direction by the same clamping cylinder 1222 to achieve synchronous length constraint of the two plates, and the positioning error is ≤0.3mm.

[0042] Furthermore, in this embodiment, the horizontal plate portion 111 is provided with two sets of mounting holes for fixing the mounting plate 1221. Along the length direction of the horizontal plate portion 111, the distance between these two sets of mounting holes is L1, which is 150mm to 300mm, preferably 200mm. When the length difference between the two T-shaped plates 20 processed before and after is ≤L1, the stroke of the cylinder 1222 is automatically compensated (the cylinder drives the T-shaped pressure plate 1223, so that the T-shaped pressure plate 1223 and the fixed stop block 121 cooperate to press the two ends of the IS plate and the No. 9 plate); when the length difference is >L1, multiple fasteners (M10 screws) need to be manually disassembled and installed to install the cylinder 1222 to the position of another set of mounting holes, and then the cylinder 1222, the T-shaped pressure plate 1223 and the fixed stop block 121 are used to press the two ends of the IS plate and the No. 9 plate.

[0043] The width positioning mechanism 13 includes an adjustable clamping assembly 131 and a width clamping assembly 132, which are located on both sides of the width direction of the horizontal plate portion 111 and on both sides of the strip hole 111a. The two work together to clamp the IS plate 21 on both sides of the width direction, thereby performing positioning.

[0044] The adjustable clamping assembly 131 includes a strip clamping plate 1311, multiple manual width adjustment components 1312, and multiple locking components 1313.

[0045] Among them, the strip pressure plate 1311 is in the shape of a long strip plate, its length is slightly less than the length of the IS plate 21, its width (height) is greater than the thickness of the IS plate 21, its length direction is consistent with the length direction of the horizontal plate portion 111, and its surface direction is perpendicular to the surface direction of the horizontal plate portion 111.

[0046] Figure 5 yes Figure 1 Enlarged view of the inner part of frame A.

[0047] like Figure 5 As shown, the manual width adjustment component 1312 includes a fixing block 13121, a manual adjustment screw 13122, and a scale (not shown in the figure). The two fixing blocks 13121 are fixed to the horizontal plate portion 111 and arranged along the width direction of the horizontal plate portion 111. The manual adjustment screw 13122 is installed in the through holes of these two fixing blocks 13121, with one end fixed to the strip-shaped pressure plate 1311, and the other end for the user to rotate, or it can also be used to install rotation auxiliary components (such as a rotating wheel).

[0048] The locking component 1313 is used to lock the position of the pressure plate 1311 after the manual width adjustment component 1312 has been adjusted to the correct position. The locking component 1313 includes a mounting block 13131, an internal thread handle 13132, and a locking block 13133. The locking block 13133 is elongated and has a slotted hole 13133a, positioned above the mounting block 13131. The internal thread handle 13132 passes through the slotted hole, with one end fixed to the mounting block 13131 and the other end (upper end in the figure) having a wedge-shaped handle. By adjusting the position of the locking block 13133 and rotating the handle, the wedge-shaped handle locks the locking block 13133, causing one end of the locking block 13133 to abut against the elongated pressure plate 1311. This locks the position of the elongated pressure plate 1311 after the manual width adjustment component 1312 has been adjusted, preventing displacement during processing.

[0049] In this embodiment, there are two manual width adjustment components 1312, each located approximately one-third of the length of the strip pressure plate 1311 from both ends. There are three locking components 1313, located at both ends and the middle of the strip pressure plate 1311. The accuracy of the manual adjustment screw 13122 is ±0.5mm. The inner thread handle 13131 is M12×1.5.

[0050] The width-direction clamping assembly 132 includes a guide rail 1321, multiple sliders (not shown in the figure), multiple clamping cylinders 1322, and multiple rectangular pressure plates 1323.

[0051] The guide rail 1321 is fixed on the horizontal plate 111, and its extension direction is consistent with the length direction of the horizontal plate 111. Multiple sliders are slidably fitted on the guide rail 1321, and multiple clamping cylinders 1322 are respectively fixed on each slider, with their piston rods facing the middle of the horizontal plate 111 and the direction of the piston rods being consistent with the width direction of the horizontal plate 111. That is, the multiple clamping cylinders 1322 are arranged parallel to each other. Multiple rectangular pressure plates 1323 are all rectangular plates and are respectively fixed on each piston rod. The width (height) of the rectangular pressure plate 1323 is also greater than the thickness of the IS plate 21.

[0052] In this embodiment, there are three sets of clamping cylinders 1322 and rectangular pressure plates 1323, and the strokes of the three clamping cylinders 1322 are the same. The model of the clamping cylinders 1322 is SC-25×25. During positioning, the user first adjusts one side of the strip pressure plate 1311 to the position corresponding to the size of the plate to be processed by manually adjusting the width adjustment component 1312, and then locks the position of the strip pressure plate 1311 by locking component 1313. Subsequently, the piston rods of multiple cylinders 1322 extend synchronously, so that the corresponding multiple pressure plates 1323 press against the side of the IS plate 21 to ensure zero-gap positioning in the width direction.

[0053] The height positioning mechanism 14 includes a support platform 141, a manual height adjustment component 142, and a lifting guide component 143. The support platform 141 supports the vertically placed No. 9 board 22, thereby positioning the No. 9 board 22 in the height direction (the width direction of the No. 9 board itself). The manual height adjustment component 142 allows the user to manually adjust the height of the support platform 141, and the lifting guide component 143 guides the support platform 141 during lifting to keep it level.

[0054] Figure 6 yes Figure 2 Enlarged view of the inner part of frame B.

[0055] like Figure 1 , Figure 2 and Figure 6 As shown, the support platform 141 includes a long, rectangular support rod 1411 and a three-layer structure consisting of a rigid substrate 1412, an elastic pad 1413, and a rigid pressure plate 1414 sequentially laid on the upper surface of the support rod 1411 to achieve elastic contact with the No. 9 plate 22. In this embodiment, the rigid substrate 1412 is made of 45# steel, the elastic pad 1413 is a silicone pad, and the rigid pressure plate 1414 is made of Q235 steel (carbon structural steel). The total thickness of these three layers is 5mm to 15mm, preferably 8mm.

[0056] The adjustable support assembly 142 includes multiple manually adjustable components 1421, which are hand-cranked screw lifting mechanisms. These include a connecting shaft 14211 and a lifting mechanism 14212 driven by the connecting shaft 14211. The lifting mechanism 14212 is mounted on the bottom beam 112, and its upper end is fixed to the bottom of the support platform 141. A hand crank component is installed at one end of the connecting shaft 14211. The user can rotate the hand crank component to cause the adjustable support assembly 142 to drive the support platform 141 to rise or fall.

[0057] In this embodiment, there are two manual height adjustment components 1421, which are respectively located at about 1 / 3 of the length of the support rod from both ends of the support assembly 142. The two manual height adjustment components 1421 can be connected by a connecting shaft 14211 and a coupling to rotate synchronously.

[0058] The lifting guide assembly 143 includes two linear guide rails 1431. Both ends of the support platform 141 are liftably mounted on the two linear guide rails 1431, thus receiving guidance during its lifting process. In this embodiment, the preload of the linear guide rails 1431 is 10N-20N, preferably 15N.

[0059] In addition, the height positioning mechanism 14 also includes multiple lifting and discharging cylinders 144, which are respectively arranged below the support platform 141. Their piston rods are vertically upward and used to lift the support platform 141 for loading and unloading. That is, the height positioning mechanism 14 also has a loading and unloading auxiliary function.

[0060] In this embodiment, the lifting and discharging cylinders 144 are of model SC-25×100, and there are three of them, which are respectively set at both ends and directly below the middle of the support platform 141. During loading (manual feeding), the piston rod of the lifting and discharging cylinder 144 retracts, causing the support platform 141 to rise to 40mm-60mm below the worktable surface, preferably 50mm, to prevent the material from being deformed by collision during feeding; after nailing is completed, the piston rod of the lifting and discharging cylinder 144 extends, causing the support platform 141 to rise 90mm-120mm, preferably 100mm, to push out the processed T-shaped material 20, making it easy for manual material removal.

[0061] The nailing mechanism 15 includes a nail gun assembly 151, a pressing assembly 152, and a translation assembly 153. The nail gun assembly 151 is used to nail the two positioned panels. The pressing assembly 152 applies downward pressure to the positioned panels to cooperate with the height positioning mechanism 14 to press the two panels together, ensuring a tight fit between the IS panel 21 and the No. 9 panel 22.

[0062] The nail gun assembly 151 can be a nail gun from the prior art. In this embodiment, the nail gun assembly 151 is a pneumatic nail gun, model ST64, with the following nail specifications: length 25mm-64mm, diameter 1.2mm-2.5mm, and nailing frequency ≤1.5 times / second.

[0063] The pressing assembly 152 includes a pressing bracket 1521, multiple elastic pressure rollers 1522, a pressing cylinder 1523, and a pressing guide component 1524.

[0064] The pressing bracket 1521 is fixed to the translation bracket of the translation assembly 153, and a pressing mating part 15211 is installed in the middle of one of its surfaces. Multiple elastic pressure rollers 1522 are respectively installed on the lower end of the pressing bracket 1521 for pressing against the upper surface of the IS plate 21. The nail gun assembly 151 is fixed to the lower part of the pressing bracket 1521 and located above the elastic pressure rollers 1522. The pressing cylinder 1523 is installed on the translation bracket, with its piston rod pointing vertically downwards and correspondingly positioned with the pressing mating part 15211. When the piston rod extends, it abuts against the pressing mating part 15211 and applies downward pressure, thereby pressing down the pressing bracket 1521 and the multiple elastic pressure rollers 1522 as a whole. The pressing guide component 1524 includes a vertical guide rail and a slider. The vertical guide rail is fixed on one surface of the translation bracket, and the slider is fixed on one surface of the upper end of the pressing bracket 1521 and slidably engaged with the vertical guide rail, thereby playing a guiding role during the pressing process.

[0065] In this embodiment, four elastic pressure rollers 1522 are arranged at the four corners of a rectangle. The elastic pressure rollers 1522 are made of polyurethane, with a diameter of 40mm-60mm, preferably 50mm, and an elastic coefficient of 20N / mm or higher. The pressing cylinder 1523 is a Festo DNC-50-30-PPV-A, which applies a downward pressure of approximately 400N-600N, preferably approximately 500N, to ensure that the bonding gap between the IS plate 21 and the No. 9 plate 22 is ≤0.1mm. Furthermore, during pressing, the plate is first pre-tightened by the multiple elastic pressure rollers 1522 with a pre-tightening force of approximately 200N, and then the nail gun assembly 151 is triggered to nail, thereby eliminating the effect of plate arching.

[0066] The translation assembly 153 includes a translation slide 1531, a translation bracket 1532, a servo motor 1533, and a synchronous belt assembly (not shown in the figure).

[0067] The translation slide 1531 is fixed at both ends to the upper ends of two columns 113, so that the translation slide 1531 is horizontally positioned above the worktable surface, and the length direction of the translation slide 1531 is consistent with the length direction of the horizontal plate 111. The translation bracket 1532 is mounted on the translation slide 1531 and can move horizontally under the drive of the translation slide 1531. The servo motor 1533 is used to drive the translation slide 1531 through a synchronous belt assembly, and its positioning accuracy is ±0.1mm.

[0068] The T-shaped board nailing device 10 may also have an automatic nailing control system, which is existing technology. The composition of the automatic nailing control system will be described exemplarily below.

[0069] Figure 7 This is a schematic diagram of the automatic nailing control system in this embodiment.

[0070] like Figure 7 As shown, the automatic nailing control system 16 may include a PLC controller 161 (industrial computer) and a human-machine interface 162. The PLC controller 161 has corresponding control logic modules (not shown in the figure) and is connected to the control components (such as solenoid valves), servo motors and nail guns of each cylinder respectively, for controlling their operation.

[0071] The human-machine interface 162 can be connected to the PLC controller 161 via Ethernet, allowing the user to input parameters such as the length, width, nail coordinates, nail spacing, and nailing depth of the IS board 21 and the No. 9 board 22. The control logic module is used to automatically calculate the nailing path and control the state of each cylinder based on the input parameters, and to control the length positioning mechanism 12, the width positioning mechanism 13, the height positioning mechanism 14, and the nailing mechanism 15 based on the calculation results, thereby positioning and nailing the corresponding boards.

[0072] In addition, the control logic module may also include a positioning compensation algorithm and a dual safety protection algorithm. The positioning compensation algorithm automatically adjusts the nailing depth to compensate for the thickness of the board. The dual safety protection algorithm includes generating corresponding alarms when any cylinder fails to position properly and stopping the machine when the nail gun's air pressure is insufficient. These algorithms are all existing technologies and will not be described in detail.

[0073] In this embodiment, the PLC controller 161 is a Siemens S7-200 SMART. The human-machine interface 162 is a 7-inch touchscreen with a resolution of 800×480. The parameters that can be input include: the length (600mm-1450mm) of the IS board 21 and the No. 9 board 22, the board width (165mm-270mm), the nail position coordinates, the nail spacing (adjustable from 50mm to 300mm), and the nailing depth (automatically compensated for the board thickness).

[0074] Through actual testing, the positioning method of the device 10 in this embodiment, which uses "manual coarse adjustment + cylinder precision setting," improves positioning efficiency by more than 40% compared with traditional manual positioning and assembly. Furthermore, the device 10 achieves elastic clamping through multiple elastic pressure rollers 1522 and the upper three-layer structure of the support platform 141 (i.e., rigid base plate 1412, elastic pad 1413, and rigid pressure plate 1414). Actual testing shows that the gap between the IS plate 21 and the No. 9 plate 22 is ≤0.1mm, and the nailing qualification rate is ≥99.5%.

[0075] Furthermore, the automatic nailing control system 16 allows for one-click input of support parameters and automatically determines nail positions and compensates for nailing depth based on these parameters, thus significantly improving nailing efficiency. Actual testing showed that using this device 10 improves nailing efficiency by more than three times compared to traditional manual nailing.

[0076] The role and effect of the embodiments

[0077] The T-shaped board positioning and nailing device provided in this embodiment includes a length positioning mechanism, a width positioning mechanism, a height positioning mechanism, and a nailing mechanism. It can position an IS board and a No. 9 board placed in a T-shape in both the length and width directions, and then nail them together, thereby efficiently producing T-shaped boards with high dimensional accuracy. Because the same length positioning mechanism is used to position the IS board and No. 9 board in the T-shape, synchronous constraint in the length direction of these two boards can be achieved, resulting in high positioning accuracy in the length direction and improving the dimensional accuracy of the finished T-shaped board. In this embodiment, actual testing showed that using this device improved positioning efficiency by more than 40%, nailing efficiency by more than 3 times, and the nailing qualification rate by ≥99.5%. Furthermore, it ensures that the gap between the IS board and the No. 9 board is ≤0.1mm, meeting the high precision requirements of the product, demonstrating significant effectiveness.

[0078] In this embodiment, a through-hole is provided on the horizontal plate of the frame, which facilitates the placement of the IS board and No. 9 board to be processed, serving as a mounting and preliminary positioning mechanism. The length positioning mechanism includes a T-shaped fixing block, a T-shaped pressure plate, and a clamping cylinder, thus conveniently and stably clamping the two ends of the two boards placed in a T-shape along their length, thereby performing length-direction positioning.

[0079] Furthermore, two sets of mounting holes are provided on the horizontal plate. The clamping cylinder is installed in one set of mounting holes by four screws. When the length difference between the plates processed before and after is relatively small, the length difference can be automatically compensated by the clamping cylinder in the length direction. When the length difference between the plates processed before and after is large, the screws can be removed and the clamping cylinder can be installed in the other set of mounting holes, so that the equipment can adapt to a large range of plate lengths.

[0080] Furthermore, the width positioning mechanism includes width clamping components and adjustable clamping components correspondingly arranged on both sides. The width clamping components use multiple clamping cylinders to press multiple rectangular pressure plates toward one side of the IS plate. The adjustable clamping components include multiple manual width adjustment parts (manual adjustment screws) and multiple locking parts (internal thread handles and locking blocks), allowing for manual adjustment by the user. The cylinders then clamp the plates to achieve positioning in the width direction, enabling the equipment to adapt to various IS plate widths without requiring complex automated control. Adjustment is achieved through a screw and scale, providing high precision to meet product manufacturing needs.

[0081] Furthermore, the height positioning mechanism includes a support platform, adjustable support components (trapezoidal screw and lifting mechanism), and lifting guide components. Therefore, the support platform can support the longitudinally placed No. 9 board, and the user can manually adjust the height of the support platform, allowing the equipment to adapt to various No. 9 board widths. The adjustment is achieved via a screw, ensuring high precision.

[0082] Furthermore, a rigid substrate, an elastic pad, and a rigid pressure plate are sequentially laid on the upper surface of the support platform. The nailing mechanism has multiple elastic pressure rollers and a pressing cylinder. Therefore, the support platform and the No. 9 plate can fit together elastically, which can prevent damage to the No. 9 plate during the positioning process. It can also cooperate with the elastic pressure rollers to press together, so that the IS plate and the No. 9 plate fit together tightly, meeting the high precision requirements of product manufacturing.

[0083] Furthermore, the height positioning mechanism also includes multiple lifting and discharge cylinders, which can lift the support platform and the T-shaped sheet metal it supports, so that the support platform can be positioned at a height that is convenient for loading, and the T-shaped sheet metal is pushed out to a height that is convenient for unloading. This gives the height positioning mechanism an auxiliary function for loading and unloading, further improving the production efficiency of T-shaped sheet metal.

[0084] Furthermore, the automatic nailing control system can automatically calculate the nailing path and control the state of each cylinder based on the input parameters, and perform corresponding control, thus greatly improving nailing efficiency.

[0085] Furthermore, the automatic nailing control system also provides a dual safety protection mechanism: it will alarm when the cylinder is not positioned correctly and will automatically stop when the nail gun air pressure is insufficient. Therefore, it also improves the safety and reliability of automatic nailing and increases the yield rate.
