[0036] Reference Figures 1 to 6 A screen cabinet installation device is used to install a screen cabinet 1 on a ground channel steel, which includes a walking frame 100, a lifting component 200, and a scanning and marking component 300. The walking frame 100 is provided with a screen cabinet accommodating position 110 and a screen cabinet entrance and exit 120 for the screen cabinet 1 to enter and exit the screen cabinet accommodating position 110, and a walking wheel 130 is provided at the lower end of the walking frame 100. The lifting component 200 is arranged on the walking frame 100, and the lifting component 200 is used to lift and lower the screen cabinet 1 located in the screen cabinet accommodating position 110. The scanning and marking component 300 is arranged on the walking frame 100 and is located at the lower end of the screen cabinet accommodating position 110. The scanning and marking component 300 can be moved away from the lower end of the screen cabinet accommodating position 110. The scanning and marking component 300 includes a hole position scanning device 310 and a marking device 320. The hole position scanning device 310 is used to obtain the position information of the installation hole at the bottom of the screen cabinet 1, and the marking device 320 is used to mark the ground channel steel.

[0037] When installing the screen cabinet 1, the screen cabinet 1 is placed in the screen cabinet accommodating position 110 of the walking frame 100 and lifted up by the lifting component 200. Then, the walking frame 100 is moved onto the ground channel steel so that the screen cabinet 1 enters above the position where it needs to be installed. Then, the scanning device 310 of the scanning and marking component 300 is used to obtain the position information of the installation hole at the bottom of the screen cabinet 1. According to the position information obtained by the scanning device 310, the ground channel steel is marked accordingly by the marking device 320. Then, the walking frame 100 and the screen cabinet 1 are removed. According to the mark on the ground channel steel, the ground channel steel is processed to form a matching structure that is adapted to the installation hole of the screen cabinet 1. Finally, the walking frame 100 is reset onto the ground channel steel, the scanning and marking component 300 is removed, and the screen cabinet 1 is lowered by the lifting component 200 to fix the screen cabinet 1 to the ground channel steel.

[0038] Through the above-mentioned screen cabinet installation device, the position of the installation hole of the screen cabinet 1 can be obtained by the hole position scanning device 310, and the marking device 320 can mark the ground channel steel, thereby avoiding the corresponding operation simply by manual labor. The operation is convenient, the labor intensity of the workers can be reduced, and the marking is accurate; in addition, when the screen cabinet 1 is in a lifted state, the hole position scanning device 310 and the marking device 320 can be used to complete the marking of the ground channel steel, thereby avoiding the screen cabinet 1 from being repeatedly lifted and lowered, reducing the possibility of damaging the screen cabinet 1.

[0039] In the embodiment, the screen cabinet installation device further includes a control host, the hole position scanning device 310 and the marking device 320 are connected to the control host, and the control host is configured to control the marking device 320 to mark the corresponding position on the ground channel steel according to the position information of the installation hole obtained by the hole position scanning device 310. By setting the control host, the hole position scanning of the installation hole and the marking of the ground channel steel can be automatically performed, with a high degree of automation and more convenient operation.

[0040] In the embodiment, the hole position scanning device 310 is a visual detection device, which includes a camera 311, and the camera 311 is arranged upward. The visual detection device can shoot the bottom of the screen cabinet 1 through the camera 311, so as to obtain the position information of the installation hole according to the image analysis.

[0041] In one embodiment, the visual inspection device can obtain the position information of the installation hole in the following manner: perform sub-pixel positioning on the photographed image of the bottom of the screen cabinet 1, find the margin of the bottom of the entire screen cabinet 1 and the margin of the installation hole, delineate the center of the bottom of the screen cabinet 1 and the center of the installation hole according to the margin of the bottom of the screen cabinet 1, take the center of the bottom of the screen cabinet 1 as the coordinate origin, find the pixel coordinates of the center of the installation hole, and obtain the spacing between the pixel points of the image through proportional conversion according to the size constant of the screen cabinet 1, and then convert the pixel coordinate value of the center of the installation hole into the real size value, so as to finally obtain the coordinate value of the center of each installation hole, and convert the coordinate value of the center of each installation hole through the coordinate axis to obtain the coordinate value of the center of each installation hole with the walking frame 100 as the reference. When the screen cabinet 1 is lifted relative to the walking frame 100 at a fixed relative position, the position difference between the two is a constant, and the coordinate axis conversion can be achieved by a simple numerical offset. When the lifting position of the screen cabinet 1 relative to the walking frame 100 is different, a visual reference object can be set on the walking frame 100, and the visual detection device will shoot the visual reference object together during shooting, and calculate the position difference between the coordinate system with the visual reference object as the origin and the coordinate system with the center of the bottom of the screen cabinet 1 as the origin. The coordinate value of the center of the installation hole is converted to the coordinate value of the coordinate system with the visual reference object as the origin through the position difference. It can be imagined that the visual detection device is not limited to obtaining the position information of the installation hole through the above method. In this field, the visual detection device is a common technology, and there are many specific implementation methods to obtain the size and position information of the object. Those skilled in the art can configure it according to the specific situation.

[0042] It is conceivable that the hole position scanning device 310 is not limited to using a visual detection device. For example, in some embodiments, the hole position scanning device 310 uses a positioning plate, which includes a substrate and a plurality of ejector pins arranged in a rectangular array on the substrate. The ejector pins can be retracted. A conductive plate corresponding to the ejector pins is arranged on the substrate. The conductive plate is divided into two non-contacting parts. When the ejector pins are compressed, they can abut against the conductive plate, so that the two separated parts of the conductive plate are conductive, and the conductive plate is electrically connected to a controller. When it is necessary to scan the installation hole of the screen cabinet 1, the positioning plate is raised by the lifting mechanism and contacts the bottom of the screen cabinet 1. The ejector pins are compressed by the bottom surface of the screen cabinet 1. The compressed ejector pins turn on the conductive plate, while the ejector pins opposite to the installation hole are inserted into the installation hole, so that the corresponding conductive plate is not turned on. The controller can determine which ejector pins are not compressed by detecting whether the conductive disk is conductive or not. Since the positions of the ejector pins on the substrate are predetermined and known, the position of the entire positioning disk relative to the walking frame 100 is also predetermined and known. The controller extracts the position information of the ejector pins that are not compressed based on the above constant information, thereby completing the position scanning of the installation holes. It is understandable that in this field, there are many technical means for scanning the hole positions to obtain the position information of the hole positions, and those skilled in the art can select appropriate technical means to achieve this according to actual conditions.

[0043] In the embodiment, the marking device 320 includes a laser head 321 and a mobile driving mechanism 322. The laser head 321 is arranged on the mobile driving mechanism 322, and the laser head 321 is arranged downward. The mobile driving mechanism 322 is used to drive the laser head 321 to move forward and backward and left and right. When it is necessary to mark the ground channel steel, according to the position information of the installation hole obtained by the hole position scanning device 310, the laser head 321 is driven to move to the corresponding position by the mobile driving mechanism 322, and a mark is engraved on the ground channel steel by laser engraving. The laser engraving method is used for marking, which has a simple structure, fast marking and accurate marking.

[0044] In the embodiment, the scanning and marking assembly 300 includes a base 330, a mobile driving mechanism 322 is arranged on the base 330, the mobile driving mechanism 322 has an end action part 3221 that can move left and right and front and back, and a laser head 321 is connected to the end action part 3221. In the embodiment, the base 330 is a square frame, the frame hole of the square frame is opposite to the lower end of the screen cabinet 1, the end action part 3221 of the mobile driving mechanism 322 moves within the vertical projection range of the frame hole of the square frame, the laser head 321 is arranged at the lower end of the end action part 3221, and the camera 311 of the visual detection device is arranged at the upper end of the end action part 3221 of the mobile driving mechanism 322. When scanning the hole position of the installation hole, the mobile driving mechanism 322 can drive the end action part 3221 to move to a suitable initial position for shooting. When marking the ground channel steel, the camera 311 may not work, and the mobile driving mechanism 322 drives the laser head 321 to move to a suitable position for marking. By adopting the above structure, the laser head 321 and the camera 311 can be integrated into one place, which can improve the compactness of the device structure. In addition, since the camera 311 is movable, it can be moved to different positions for shooting, which can achieve more flexible and targeted shooting. For example, it can be moved to the corresponding position of each installation hole and then shoot, so as to improve the accuracy.

[0045] In an embodiment, the mobile driving mechanism 322 includes an end action part 3221, a connecting seat 3222, a front and rear driving assembly and a left and right driving assembly. The connecting seat 3222 is movably arranged on the base 330 along the front and rear direction, the end action part 3221 is movably arranged on the connecting seat 3222 along the left and right direction, the front and rear driving assembly is arranged on the base 330 and is used to drive the connecting seat 3222 to move forward and backward, and the left and right driving assembly is arranged on the connecting seat 3222 and is used to drive the end action part 3221 to move left and right.

[0046] In the embodiment, the left and right ends of the connecting seat 3222 are respectively slidably set on the left and right frame bars of the base 330, the front and rear drive components include a first motor 3223, a plurality of first synchronous wheels 3224, a first synchronous belt 3225 and two driving members 3226, the four corners of the base 330 are rotatably provided with first synchronous wheels 3224, two first synchronous wheels 3224 are respectively provided at the two corners on the front side and the two first synchronous wheels 3224 are arranged obliquely, the first synchronous belt 3225 is tightened on the first synchronous wheel 3224 and forms a U-shaped circulating belt, and the U-shaped circulating belt includes three sections of double belt segments, namely, a left double belt segment, a right double belt segment, and a right double belt segment. The left and right double belt segments and the front double belt segments correspond to the left and right frame strips and the front frame strip of the base 330 respectively. The left and right double belt segments are extended front and back, and the front double belt segments are extended left and right. Two driving members 3226 are connected to the left and right ends of the connecting seat 3222 respectively. The driving member 3226 on the left is fixed to the outer belt of the left double belt segment and the driving member 3226 on the right is fixed to the inner belt of the right double belt segment (or the driving member 3226 on the left is fixed to the inner belt of the left double belt segment and the driving member 3226 on the right is fixed to the outer belt of the right double belt segment). When the first motor 3223 drives the first synchronous wheel 3224 to rotate forward and reverse, it can drive the first synchronous belt 3225 to move forward and reversely. The first synchronous belt 3225 drives the connecting seat 3222 to move forward and backward through the two driving members 3226. The structure that two left and right driving members 3226 are used to drive the connecting seat 3222 to move forward and backward is adopted, and the connecting seat 3222 moves smoothly and steadily. In addition, by forming the first synchronous belt 3225 into a U-shaped circulating belt structure, and cleverly fixing the two driving members 3226 to the inner and outer belt segments of the left double belt segment and the right double belt segment, respectively, the drive in the same direction is ensured, and the structural design is clever. Of course, it is conceivable that in some embodiments, the front and rear drive components are not limited to the above-mentioned structure. For example, the front and rear drive components use a linear motor, a motor-driven screw mechanism, etc. to drive the connecting seat 3222 to move forward and backward, and the specific configuration can be made according to actual conditions.

[0047] In the embodiment, the left and right drive components include two second synchronous wheels 3227, a second synchronous belt 3228 and a second motor 3229. The two second synchronous wheels 3227 are rotatably arranged at the left and right ends of the connecting seat 3222 respectively. The second synchronous belt 3228 is tightened on the two second synchronous wheels 3227. The second motor 3229 is connected to one of the second synchronous wheels 3227 and is used to drive it to rotate. The end action part 3221 is fixed to a side belt segment of the second synchronous belt 3228. When the second motor 3229 drives the second synchronous wheel 3227 to rotate forward and reverse, the second synchronous belt 3228 can be driven to perform forward and reverse cyclic motion, thereby driving the end action part 3221 to move left and right. Of course, it is conceivable that in some embodiments, the left and right drive components are not limited to the above-mentioned structure. For example, the left and right drive components use a linear motor, a motor-driven screw mechanism, etc. to drive the end action part 3221 to move left and right. The specific configuration can be made according to actual conditions.

[0048] It is conceivable that the marking device 320 is not limited to the above-mentioned structure. For example, the marking device 320 includes a marking pen and a driving mechanism for driving the marking pen to move, and marking is performed by the marking pen, or the marking device 320 includes a carving knife and a driving mechanism for driving the carving knife to move, and marking is performed by the carving knife. It is understandable that in this field, there are many technical means to achieve marking of a certain position, and technical personnel in this field can make settings according to actual conditions.

[0049] In an embodiment, the control host can control the mobile drive mechanism 322 of the marking device 320 according to the position information of the mounting hole obtained by the hole position scanning device 310, so that the laser head 321 moves to the corresponding position for marking, thereby realizing the automatic operation of hole position scanning to marking. It is conceivable that in some embodiments, the process of hole position scanning to marking is not limited to automatic operation through the control host, for example, the hole position scanning device 310 displays the obtained position information of the mounting hole on the display screen, and the operator manually controls the marking device 320 to mark the corresponding position according to the relevant information.

[0050] In an embodiment, the control host may be an industrial computer, PLC, etc. In an embodiment, the hole position scanning device 310 specifically adopts a visual inspection device, and the data processing module of the visual inspection device can be combined with the control host to form a comprehensive information processing center and control center.

[0051] In the embodiment, a screen cabinet limiting structure 400 is provided on the walking frame 100 for limiting the screen cabinet 1 along the front and rear and left and right directions, so that the screen cabinet 1 can be positioned to prevent it from shaking randomly. Since the position of the screen cabinet 1 is stable, the error of scanning the installation holes can also be reduced.

[0052] In the embodiment, the screen cabinet limiting structure 400 includes four positioning members 410, which are detachably arranged on the walking frame 100. The four positioning members 410 are respectively arranged corresponding to the four corners of the screen cabinet accommodating position 110, and the positioning members 410 are provided with right-angle grooves 411 for cooperating with the four corners of the screen cabinet 1. Before the screen cabinet 1 enters the screen cabinet accommodating position 110 of the walking frame 100, the positioning member 410 can be removed first. After the screen cabinet 1 enters the screen cabinet accommodating position 110 and is lifted, the positioning member 410 can be reinstalled to position the screen cabinet 1. The above-mentioned screen cabinet limiting structure 400 has a simple structure and is easy to implement. In the embodiment, the positioning member 410 includes an L-shaped plate 412, a right-angle groove 411 is formed in the L-shaped plate 412, a plug-in portion 413 is connected to the back side of the L-shaped plate 412, the plug-in portion 413 is provided with a vertically extending plug-in hole 4131, and the walking frame 100 is provided with a plug-in column 140 at a position corresponding to the positioning member 410, the plug-in column 140 and the plug-in hole 4131 are adapted to each other, and when installing and disassembling the positioning member 410, the positioning member 410 can be operated vertically, which is convenient for installation and disassembly, and the vertical installation and disassembly method is not easy to interfere with the screen cabinet 1.

[0053] It is conceivable that the screen cabinet limiting structure 400 is not limited to the above-mentioned implementation mode. For example, the screen cabinet limiting structure 400 is a clamping mechanism, and the clamping mechanism is provided with two clamping parts, and the two clamping parts are respectively located on both sides of the screen cabinet 1, and the clamping parts are respectively driven by a linear drive to move, and the linear drive is, for example, an electric push rod or a linear motor. When it is necessary to position the screen cabinet 1, the linear drive drives the clamping parts to approach each other, thereby clamping the screen cabinet 1 to achieve its positioning. At least two groups of clamping mechanisms are provided, which clamp the screen cabinet 1 from the front and back and left and right directions respectively, thereby achieving limitation in two directions. In order to prevent the screen cabinet 1 from being skewed after being clamped, the following structure and control method can be further adopted: the clamping part is provided with a pressure sensor, and when the two clamping parts are close to each other, if one of the clamping parts detects that the clamping part has touched the screen cabinet 1 through the pressure sensor, the corresponding linear drive stops driving the clamping part until the other clamping part also detects that it has touched the screen cabinet 1 through the pressure sensor, and the linear drives corresponding to the two clamping parts then synchronously drive the two clamping parts to approach each other to clamp the screen cabinet 1. In the above manner, the screen cabinet 1 can be prevented from being skewed and the subsequent scanning and marking of the installation holes can be avoided.

[0054] In the embodiment, a sliding fit structure 150 is provided at the lower part of the walking frame 100, and the sliding fit structure 150 is provided with a slide rail portion provided along the front-back direction, and the scanning and marking component 300 is detachably slidably fitted with the slide rail portion, and the walking frame 100 is also provided with a component positioning structure for positioning the position of the scanning and marking component 300. With the above structure, the scanning and marking component 300 and the sliding fit structure 150 form a drawer-like structure, which is convenient for assembly and disassembly. By providing the component positioning structure, the position of the scanning and marking component 300 relative to the walking frame 100 can be positioned, thereby ensuring that the scanning and marking component 300 will not move randomly, avoiding affecting the scanning installation hole and the accuracy of marking.

[0055] In the embodiment, the sliding matching structure 150 includes a slide member 151 provided on the left and right sides of the walking frame 100, and the slide rail portion is a slide extending along the front-to-back direction on the slide member 151, and the left and right end sides of the scanning and marking component 300 are respectively slidably provided on the slides of the two slide members 151. When disassembling the scanning and marking component 300, it can be pulled out backwards, and when installing the scanning and marking component 300, it can be inserted forwards. Of course, it is conceivable that in some embodiments, the sliding matching structure 150 is not limited to the use of two slide members 151, for example, it can also be a guide slider extending forward and backward, and the scanning and marking component 300 can be provided with a corresponding slide for matching.

[0056] In the embodiment, the component positioning structure may adopt pins, and pin holes are provided at corresponding positions of the scanning and marking component 300 and the walking frame 100. When the scanning and marking component 300 is installed on the walking frame 100, the positioning can be achieved by inserting the pins into the walking frame 100 and the pin holes of the scanning and marking component 300. Of course, the component positioning structure may also adopt other structures, such as a clamping positioning structure, etc., which may be specifically configured according to actual conditions.

[0057] It is conceivable that the scanning and marking component 300 is not limited to the structure that can be moved away from the lower end of the screen cabinet accommodating position 110 in the above-mentioned manner. For example, the scanning and marking component 300 is movably connected to the walking frame 100, and the walking frame 100 is provided with a driving mechanism for driving the component to move. When the scanning and marking component 300 needs to be moved away, it can be driven to move away by the driving mechanism. The active connection between the scanning and marking component 300 and the walking frame 100 can be a linear sliding connection or a rotating connection, and the driving mechanism that drives its movement can be adaptively configured according to the specific active connection method.

[0058] In an embodiment, the travel wheel 130 is an electric travel wheel, so that it can be moved electrically, reducing the labor intensity of workers.

[0059] In an embodiment, the electric walking wheel 130 is electrically connected to the control host, so that it can be controlled by the control host. After completing the marking of the ground channel steel, when the walking frame 100 and the screen cabinet 1 are removed, the control host controls the electric walking wheel 130 to walk a predetermined distance in a predetermined direction. After completing the processing of the matching structure of the ground channel steel, the control host resets the same distance in the opposite direction of the previous movement, so that the screen cabinet 1 can be reset to the original scanning and marking position, thereby realizing a fast and accurate reset operation.

[0060] In some embodiments, accurate resetting of the screen cabinet 1 can also be achieved through other structures and methods, such as setting at least two laser heads 321, each laser head 321 moves independently through a one-to-one corresponding mobile drive mechanism 322, and after completing the processing of the matching structure of the ground channel steel, when the walking frame 100 and the screen cabinet 1 are moved and reset, the laser head 321 moves to the position corresponding to the mounting hole of the screen cabinet 1, and emits a laser coaxial with the mounting hole to indicate the position of the mounting hole. When resetting the position of the walking frame 100 and the screen cabinet 1, the laser emitted by the laser head 321 is used to align with the matching structure of the ground channel steel. Since at least two laser heads 321 are set, the screen cabinet 1 can be accurately positioned and accurately reset by aligning at least two points, which facilitates the subsequent accurate placement of the screen cabinet 1 on the ground channel steel. In the above structure, at least two laser heads 321 are set, which can also speed up the marking speed and improve the work efficiency.

[0061] In the embodiment, the lifting assembly 200 includes a winding motor 210 and a lifting rope 220. The lifting rope 220 is used to connect with the screen cabinet 1. The winding motor 210 is arranged at the upper end of the walking frame 100. The lifting rope 220 is connected to the winding drum of the winding motor 210. When the winding motor 210 drives the winding drum to rotate forward and reverse, the lifting rope 220 can be wound and loosened by the winding drum, thereby lifting and lowering the screen cabinet 1. It is conceivable that the lifting assembly 200 is not limited to the above-mentioned structure. For example, the lifting assembly 200 adopts the structure of a hydraulic cylinder, an electric cylinder, etc. The action rod of the hydraulic cylinder or the electric cylinder is connected to the hook, and the hook is connected to the screen cabinet 1, so that the screen cabinet 1 can be lifted and lowered. It is understandable that in this field, there are many implementation methods for the mechanism for lifting and lowering objects, and those skilled in the art can configure according to actual conditions.

[0062] The screen cabinet installation method provided by the present invention comprises the following steps:

[0063] S1: Obtain the screen cabinet installation device, move the walking frame 100, remove the scanning and marking component 300 from the lower end of the screen cabinet accommodating position 110, so that the screen cabinet 1 enters the screen cabinet accommodating position 110 through the screen cabinet entrance and exit 120, lift the screen cabinet 1 through the lifting component 200, so that the screen cabinet 1 is off the ground, and reset the scanning and marking component 300 to the lower side of the screen cabinet 1;

[0064] S2: Move the walking frame 100 so that the walking frame 100 and the screen cabinet 1 are moved to the top of the ground channel steel, and obtain the position information of the installation holes at the bottom of the screen cabinet 1 through the hole position scanning device 310. According to the position information obtained by the hole position scanning device 310, mark the position of the corresponding installation hole of the ground channel steel through the marking device 320;

[0065] S3: Move the walking frame 100 and process a matching structure corresponding to the installation holes of the screen cabinet 1 at the marked part of the ground channel steel;

[0066] S4: Reset the walking frame 100, remove the scanning and marking component 300, lower the screen cabinet 1 to the ground channel steel through the lifting component 200, and fix the screen cabinet 1 to the ground channel steel through the matching structure of the ground channel steel and the installation holes of the screen cabinet 1.

[0067] The installation of the screen cabinet 1 is realized by the above method, which is easy to operate and can reduce the labor intensity of workers. The screen cabinet 1 is lifted and lowered less frequently, thereby reducing the probability of damaging the screen cabinet 1 due to repeated lifting and lowering operations.

[0068] In an embodiment, the matching structure may be a screw hole, which is tapped after being bored at the mark of the ground channel steel by a hole-turning device. When fixing the screen cabinet 1, the screw is passed through the mounting hole of the screen cabinet 1 and then threaded into the screw hole on the ground channel steel. In some embodiments, the matching structure may also be a stud, which is welded to the mark of the ground channel steel. When fixing the screen cabinet 1, the stud is passed through the mounting hole of the screen cabinet 1 and is fixed to the stud by a nut and a pressure plate.

[0069] The technical features of the above embodiments may be combined arbitrarily.
