Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of construction engineering plastering construction, specifically to: 1) a construction engineering plastering construction process and system using three-dimensional optical scanning technology; 2) a method, device and computer-readable storage medium for generating construction engineering plastering control target information; and 3) a method and device for positioning construction engineering plastering control target calibration parts. Background Art

[0002] Plastering in construction projects is a traditional decorative technique that applies mortar to surfaces such as walls and ceilings. For plastering on pre-built walls awaiting plastering, the traditional construction method is target-punching and rib-punching. Target-punching involves preparing standard mortar cakes before plastering. Based on the required thickness of the wall plaster, a standard cake is made above each corner. Additional cakes are drawn using a line at the window and buttress corners. A plumb line is then used to make standard mortar cakes at the lower corners of the wall. Ribbing is also a crucial step in ensuring plastering quality. Ribbing involves creating a mortar strip between the upper and lower mortar cakes. Its height is the same as the mortar cakes, with beveled edges. This serves as a crucial control feature when plastering large areas. Because pre-built walls often have uneven flatness and are prone to bulges, and because target-punching and rib-punching rely heavily on manual experimentation, which often results in significant errors, the flatness and verticality of the wall surface after target-punching and rib-punching plastering is often suboptimal.

DETAILED DESCRIPTION

[0050] The following is a clear and complete description of the embodiments of the present invention in conjunction with the accompanying drawings. A person skilled in the art will be able to implement the embodiments of the present invention based on these descriptions. Before describing the embodiments of the present invention in conjunction with the accompanying drawings, it should be noted that:

[0051] The technical solutions and technical features provided in each section, including the following description, may be combined with each other unless they conflict. In addition, where possible, these technical solutions, technical features, and related combinations may be assigned specific technical themes and protected by relevant patents.

[0052] The embodiments of the present invention involved in the following description are generally only a part of the embodiments rather than all the embodiments. Based on these embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of patent protection.

[0053] The terms "include," "comprising," "having," and any variations thereof in this specification, the corresponding claims, and related parts are intended to cover non-exclusive inclusions. Other related terms and units are to be reasonably interpreted based on the relevant content provided in this specification.

[0054] The traditional plastering process for pre-built walls is a target-punching process. This is because the flatness of pre-built walls is often uneven, with convex ridges distributed across the wall surface. Furthermore, target-punching relies heavily on manual experimentation, which often results in significant errors. Consequently, the flatness and verticality of the wall surface after target-punching plastering is less than ideal. To address these issues, a construction engineering plastering process and system using 3D optical scanning technology is provided.

[0055] Figure 1 FIG. 1 is a schematic diagram showing the principle of a construction engineering plastering construction system using three-dimensional optical scanning technology according to an embodiment of the present invention. Figure 1 As shown, the construction engineering plastering construction system using three-dimensional optical scanning technology specifically includes: three-dimensional optical scanning equipment 1, computer modeling equipment 2, construction engineering plastering control target information generation equipment 3, construction engineering plastering control target calibration part positioning equipment 4, plastering control target positioning device 5 and plastering control target calibration part cutting device 6.

[0056] Among them, the three-dimensional optical scanning device 1 is used to obtain a measured model of the wall surface that has been built and is to be plastered. In a preferred embodiment, the three-dimensional optical scanning device 1 adopts a three-dimensional laser scanner; in this case, the measured model may include a fitting surface obtained by collecting point cloud data of the wall surface that has been built and is to be plastered through three-dimensional laser scanning. Three-dimensional laser scanning technology is a scanning technology that integrates computer technology, optoelectronic technology, and precision machinery manufacturing and processing. It can quickly measure the shape, size, and spatial position of the target from a complex entity or real scene, and form high-density point cloud data of the target surface. After scanning, the point cloud data and image data can be texture mapped to generate a high-precision three-dimensional model (measured model). Its ranging accuracy is at the millimeter level, the angle measurement accuracy is at the second level, and the point position accuracy is at the millimeter level. Generally, it only takes a few seconds to complete a panoramic scan, so it has the advantages of accurate measurement and high efficiency.

[0057] The computer modeling device 2 is used to obtain a design model corresponding to the masonry wall surface to be plastered. Generally speaking, the computer modeling is performed using computer-aided design (CAD) software. Computer-aided design (CAD) is a common method used in the market. Commercially available or self-developed CAD software can be directly used and installed and run on a computer hardware system to establish the computer modeling device 2.

[0058] The construction project plastering control target information generation device 3 is used to obtain the measured model and the design model and compare and analyze the measured model with the design model to generate plastering control target information. The plastering control target information includes plastering control target positioning information and plastering control target calibration part thickness information. The plastering control target positioning information is used to determine the specific position of the plastering control target calibration part installed on the built wall to be plastered. The plastering control target calibration part thickness information is used to determine the corresponding thickness of the plastering control target calibration part. When plastering construction is carried out on the built wall to be plastered, the thickness of the plastering control target calibration part protruding from the built wall to be plastered is used as a scale to control the plastering thickness of the surrounding area of ​​the plastering control target calibration part.

[0059] Generally speaking, the construction engineering plastering control target information generation device 3 includes at least a processor coupled to a memory, the memory being configured to store computer programs or instructions. The processor is configured to execute the computer programs or instructions in the memory, causing the construction engineering plastering control target information generation device to perform the following construction engineering plastering control target information generation method. The method at least includes: obtaining a measured model of a masonry wall surface to be plastered obtained by three-dimensional optical scanning; obtaining a design model corresponding to the masonry wall surface to be plastered obtained by computer modeling; and comparing and analyzing the measured model with the design model to generate plastering control target information.

[0060] The internal algorithm of the construction project plastering control target information generating device 3 specifically used to generate the plastering control target information can be designed based on the principle that the thickness distribution of the plaster layer formed by the plastering construction based on the plastering control target information can better compensate for the error distribution between the actual masonry wall surface to be plastered and the designed masonry wall surface to be plastered, so that the actual plastered wall surface as a whole is closer to the designed plastered wall surface.

[0061] In a specific embodiment of the present invention, when determining the positioning information of the plastering control target points, the basic principle is to uniformly distribute the plastering control target points on the wall surface that has been built and is to be plastered. When determining the thickness information of the plastering control target calibration piece, the flatness, verticality, room span and depth dimensions, and the designed minimum plastering thickness parameters of the wall surface that has been built and is to be plastered are used as control conditions. This forms the basic principle of compensating for the flatness and verticality errors of the wall surface that has been built and is to be plastered as much as possible while ensuring the room span and depth dimensions and the designed minimum plastering thickness. For the wall convex hull problem, the above basic principle is used as a prerequisite. When the wall convex hull exists and makes the prerequisite difficult to meet, the wall convex hull is removed. At this time, the construction engineering plastering control target point information generation device 3 can generate an indication of the range of convex hulls to be removed to indicate to the operator the wall convex hulls that need to be removed.

[0062] The construction project plastering control target calibration part positioning device 4 is used to obtain the plastering control target information and the real-time position information of the plastering control target positioning device 5, and compare the real-time position information with the plastering control target positioning information, and then judge whether the real-time position of the plastering control target positioning device 5 meets the requirements of the plastering control target positioning information based on the comparison result. When it is judged that the real-time position of the plastering control target positioning device meets the requirements of the plastering control target positioning information, a plastering control target positioning device positioning success notification is generated and provided to the operator; when it is judged that the real-time position of the plastering control target positioning device does not meet the requirements of the plastering control target positioning information, a plastering control target positioning device movement indication notification is generated and provided to the operator.

[0063] Generally speaking, the construction engineering plastering control target calibration part positioning device 4 includes at least a processor, the processor is coupled to a memory, the memory is used to store computer programs or instructions, and the processor is used to execute the computer programs or instructions in the memory, so that the construction engineering plastering control target calibration part positioning device 4 performs the following construction engineering plastering control target calibration part positioning method. The method at least includes: obtaining plastering control target information; obtaining real-time position information of the plastering control target positioning device 5; comparing the real-time position information with the plastering control target positioning information, and judging whether the real-time position of the plastering control target positioning device 5 meets the requirements of the plastering control target positioning information according to the comparison result; when it is judged that the real-time position of the plastering control target positioning device meets the requirements of the plastering control target positioning information, a plastering control target positioning device positioning success notification is generated and provided to the operator; when it is judged that the real-time position of the plastering control target positioning device does not meet the requirements of the plastering control target positioning information, a plastering control target positioning device movement instruction notification is generated and provided to the operator.

[0064] The plastering control target positioning device 5 is a handheld device that can be movably placed against the built wall to be plastered, and has a target position auxiliary marking part for auxiliary marking the specific installation position of the plastering control target calibration part on the built wall to be plastered, a first measuring part for measuring the horizontal position of the target position auxiliary marking part on the built wall to be plastered, and a second measuring part for measuring the vertical position of the target position auxiliary marking part on the built wall to be plastered. The real-time position information is the real-time measurement result of the first measuring part and the real-time measurement result of the second measuring part. In a preferred embodiment, the plastering control target positioning device 5 is integrated with the construction engineering plastering control target calibration part positioning device 4. In this case, the construction engineering plastering control target calibration part positioning device 4 is integrated into the handheld device.

[0065] The plastering control target calibration piece cutting device 6 is used to obtain a cutting instruction, wherein the cutting instruction includes a cutting length set according to the thickness information of the plastering control target calibration piece. The plastering control target calibration piece cutting device 6 is also used to cut the rod to be cut according to the cutting length to obtain the plastering control target calibration piece. The specific structure of the plastering control target calibration piece cutting device 6 is easy to implement. For example, the plastering control target calibration piece cutting device 6 can include three parts: a feeding mechanism, a cutting length control mechanism, and a cutting mechanism. The feeding mechanism is used to transport the rod to be cut to the cutting mechanism, the cutting mechanism is used to cut the rod to be cut, and the cutting length control mechanism is used to control the relative position between the rod to be cut and the cutting mechanism so that the plastering control target calibration piece obtained by cutting meets the required thickness (i.e., the axial length of the plastering control target calibration piece).

[0066] In a preferred embodiment, the cutting instruction should be issued by the construction engineering plastering control target calibration part positioning device 4. In this way, during the positioning process of the plastering control target calibration part, the construction engineering plastering control target calibration part positioning device 4 can issue a cutting instruction to the plastering control target calibration part cutting device, so that the plastering control target calibration part currently being positioned corresponds to the plastering control target calibration part cut by the plastering control target calibration part cutting device 6, effectively avoiding confusion between different plastering control target calibration parts. Correspondingly, the construction engineering plastering control target calibration part positioning device 4 should also be given the function of being able to issue a cutting instruction to the plastering control target calibration part cutting device 6 after obtaining the plastering control target information.

[0067] Figure 2 FIG. 1 is a flow chart of a construction engineering plastering construction process using three-dimensional optical scanning technology according to an embodiment of the present invention. Figure 2 As shown, the construction engineering plastering construction process using 3D optical scanning technology uses Figure 1 The construction engineering plastering construction system shown in the figure uses the three-dimensional optical scanning technology, and specifically includes the following steps.

[0068] Step S101: Obtain a measured model of a built wall to be plastered by 3D optical scanning, and obtain a design model corresponding to the built wall to be plastered by computer modeling. This step requires the use of a 3D optical scanning device 1 and a computer modeling device 2.

[0069] Step S102: The construction engineering plastering control target information generating device 3 compares and analyzes the measured model with the design model to generate plastering control target information. The plastering control target information includes plastering control target location information and plastering control target calibration piece thickness information.

[0070] Step S103: After the construction engineering plastering control target point information generating device 3 generates the plastering control target information, a measured model diagram of the constructed wall surface to be plastered, including the plastering control target information, is displayed on the display of the construction engineering plastering control target information generating device 3. The measured model diagram of the constructed wall surface to be plastered includes information indicating the positions of the plastering control target points. Furthermore, the measured model diagram of the constructed wall surface to be plastered also includes a wall surface convex hull distribution diagram, which includes information indicating the range of convex hulls to be removed.

[0071] Step S104: performing planing construction on the convex humps to be removed on the built wall surface to be plastered according to the indication information of the range of the humps to be planed.

[0072] Step S105: Provide the plastering control target information to the construction engineering plastering control target calibration part positioning device 4, and then implement the construction engineering plastering control target calibration part positioning method. In this process, when the construction engineering plastering control target calibration part positioning device 4 provides the operator with a notification that the plastering control target positioning device has been successfully positioned, the target position auxiliary marking part is used to mark the wall surface that has been built to be plastered (for example, draw a line on the wall surface that has been built to be plastered). When the construction engineering plastering control target calibration part positioning device 4 provides the operator with a notification of movement of the plastering control target positioning device, the handheld device is moved on the wall surface that has been built to be plastered according to the notification of movement of the plastering control target positioning device (see Figure 9 As shown), until the construction engineering plastering control target point calibration piece positioning device 4 provides the operator with a notification of successful positioning of the plastering control target point positioning device.

[0073] Step S106: The construction engineering plastering control target calibration piece positioning device 4 sends a cutting instruction to the plastering control target calibration piece cutting device 6. The cutting instruction includes a cutting length set according to the thickness information of the plastering control target calibration piece.

[0074] Step S107: the plastering control target point calibration piece cutting device 6 cuts the bar to be cut according to the cutting length to obtain the plastering control target point calibration piece.

[0075] Step S108: Install the target point calibration component of the control plastering control according to the mark made on the wall to be plastered by the target point auxiliary marking part (for example, by pasting the target point, see Figure 11 As shown) at the corresponding position of the built wall to be plastered.

[0076] Step S109: performing plastering construction on the built wall surface to be plastered, wherein the thickness of the plastering control target calibration piece protruding from the built wall surface to be plastered is used as a scale to control the plastering thickness in the surrounding area of ​​the plastering control target calibration piece.

[0077] Since the construction engineering plastering control target information generating device 3 compares and analyzes the measured model of the built wall to be plastered obtained by three-dimensional optical scanning and the design model corresponding to the built wall to be plastered obtained by computer modeling to generate plastering control target information, the thickness distribution of the plastering layer formed by the subsequent plastering construction based on the plastering control target information can better compensate for the error distribution between the actual built wall to be plastered and the designed built wall to be plastered, which helps to make the actual plastered wall as a whole closer to the designed plastered wall.

[0078] The following further describes the details and improvements of the construction engineering plastering construction system using the three-dimensional optical scanning technology, the construction engineering plastering construction process using the three-dimensional optical scanning technology, and the equipment and steps involved.

Figure 3 As shown, the construction engineering plastering control target point information generating device 3 includes a processor 31, a memory 32, an input device 33, an output device 34, and a communication device 35.

[0080] The processor 31 may include a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, an application-specific integrated circuit (ASIC), a microcontroller (MCU), a field-programmable gate array (FPGA), or one or more integrated circuits for performing logical operations. The processor 31 may be used to implement the required functions of the construction engineering plastering control target information generation device 3, such as controlling the entire construction engineering plastering control target information generation device 3, executing software programs, and processing software program data. The software may be software for implementing the construction engineering plastering control target information generation method according to an embodiment of the present invention.

By way of example, and not limitation, memory 32 may include a hard disk drive (HDD), a floppy disk drive, flash memory, an optical disk, a magneto-optical disk, a magnetic tape, or a Universal Serial Bus (USB) drive, or a combination of two or more of these. Where appropriate, memory 32 may include removable or non-removable (or fixed) media. Where appropriate, memory 32 may be internal or external to processor 31. In a specific embodiment, memory 32 is a non-volatile solid-state memory. In a specific embodiment, memory 32 includes read-only memory (ROM); where appropriate, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM), or flash memory, or a combination of two or more of these.

[0082] The input device 33 communicates with the processor 31 and can accept user input in various ways. For example, the input device 33 can be a mouse, a keyboard, a touch screen device, or a sensor. The output device 34 communicates with the processor 31 and can display information in various ways. For example, the output device 34 can be various displays, such as a liquid crystal display, a light emitting diode display device, a cathode ray tube display device, or a projector.

[0083] The communication device 35 can be used to support the communication between the construction engineering plastering control target point information generation device 3 and the three-dimensional optical scanning device 1, the computer modeling device 2 and the construction engineering plastering control target point calibration part positioning device 4 respectively.

[0084] Figure 4 The present invention is a flowchart of a method for generating target point information for plastering control in a construction project according to an embodiment of the present invention. Figure 4 The construction engineering plastering control target information generation method shown is based on Figure 3 The construction engineering plastering control target information generating device shown in FIG. Figure 4 As shown, the method for generating control target point information of plastering of a construction project includes obtaining a measured model of a built wall surface to be plastered obtained by three-dimensional optical scanning, obtaining a design model corresponding to the built wall surface to be plastered obtained by computer modeling, and performing a comparison analysis between the measured model and the design model to generate the plastering control target information.

In addition, the measured model diagram of the built wall surface to be plastered also contains a wall convexity distribution diagram, which contains information indicating the range of convexities to be removed. Since wall convexities are often distributed on the built wall surface to be plastered, when the processor 31 compares and analyzes the measured model with the design model to generate the plastering control target point information, some wall convexities may constitute interference factors in the comparison and analysis algorithm. By generating the range of convexities to be removed on the wall convexity distribution diagram and then manually removing the corresponding wall convexities according to the range of convexities to be removed, the quality of the plastering construction can be further improved.

[0085] After generating the plastering control target information, the plastering control target information can also be stored as a corresponding computer-readable file. The computer-readable file can be stored on a removable data storage medium (such as a mobile hard disk, SD card, USB memory, etc.) through the communication device 35, and then the computer-readable file can be transferred to the construction project plastering control target calibration part positioning device 4 through the removable data storage medium.

[0086] Figure 5 This is a schematic diagram of the principle of a construction engineering plastering control target calibration component positioning device according to an embodiment of the present invention. Figure 5 As shown, the construction engineering plastering control target calibration part positioning device 4 is a handheld device that can be movably attached to the built wall to be plastered, which specifically includes a processor 41, a memory 42, an input device 43, an output device 44, a communication device 45, a target position auxiliary marking part 46, a first measuring part 47 and a second measuring part 48.

[0087] The processor 41 may include a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, an application-specific integrated circuit (ASIC), a microcontroller (MCU), a field-programmable gate array (FPGA), or one or more integrated circuits for implementing logical operations. The processor 41 may be used to implement the required functions of the construction engineering plastering control target calibration component positioning device 4, such as controlling the entire construction engineering plastering control target calibration component positioning device 4, executing software programs, processing software program data, etc. The software may be software for implementing the construction engineering plastering control target calibration component positioning method according to an embodiment of the present invention.

[0088] Memory 42 may include a large-capacity memory for data or instructions. By way of example, and not limitation, memory 42 may include a hard disk drive (HDD), a floppy disk drive, flash memory, an optical disk, a magneto-optical disk, a magnetic tape, or a Universal Serial Bus (USB) drive, or a combination of two or more of these. Where appropriate, memory 42 may include removable or non-removable (or fixed) media. Where appropriate, memory 42 may be internal or external to processor 41. In a specific embodiment, memory 42 is a non-volatile solid-state memory.

Output device 44 communicates with processor 41 and can display information in various ways. For example, output device 44 can be various displays, such as a liquid crystal display, a light emitting diode display device, a cathode ray tube display device, or a projector.

[0090] The communication device 45 can be used to support the communication between the construction engineering plastering control target calibration part positioning device 4 and the construction engineering plastering control target information generating device 3 and the plastering control target calibration part cutting device 6 respectively. These communications can be wireless communication, wired communication or communication achieved through removable data storage media (such as mobile hard disk, SD card, USB memory, etc.).

[0091] The target position auxiliary marking part 46 is used to auxiliary mark the specific installation position of the plastering control target calibration part on the built wall to be plastered. Specifically, it is a position indicator mark set on the housing of the handheld device. The position indicator mark is used to manually draw lines on the built wall to be plastered.

[0092] The first measuring part 47 is used to measure the horizontal position of the target position auxiliary marking part 46 on the built wall to be plastered. Specifically, a horizontal infrared rangefinder is used. The relative position between the horizontal infrared rangefinder and the target position auxiliary marking part 46 is fixed. When in use, the wall at the side corner of the built wall to be plastered (if there is no wall, a baffle is placed artificially) is used as the reference plane. The horizontal distance between the horizontal infrared rangefinder and the wall is measured by the horizontal infrared rangefinder, so that the horizontal position of the target position auxiliary marking part 46 on the built wall to be plastered can be obtained.

[0093] The second measuring part 48 is used to measure the vertical position of the target position auxiliary marking part 46 on the built wall to be plastered. Specifically, a vertical infrared rangefinder is used. The relative position between the vertical infrared rangefinder and the target position auxiliary marking part 46 is fixed. When in use, the top plate or bottom plate adjacent to the built wall to be plastered is used as the reference plane. The vertical distance between the vertical infrared rangefinder and the reference plane is measured by the vertical infrared rangefinder, so that the vertical position of the target position auxiliary marking part 46 on the built wall to be plastered can be obtained.

[0094] The first measuring unit 47 and the second measuring unit 48 communicate with the processor 41 so that the processor 41 can compare the real-time position information with the plastering control target positioning information, and determine whether the real-time position of the construction engineering plastering control target calibration part positioning device 4 meets the requirements of the plastering control target positioning information based on the comparison results.

[0095] visible, Figure 5 The construction engineering plastering control target point calibration piece positioning device 4 shown has integrated the plastering control target point positioning device 5.

[0096] Figure 6 The present invention is a flowchart of a method for positioning a target calibration part for plastering control in a construction project according to an embodiment of the present invention. Figure 6 The positioning method of the target calibration part of the construction engineering plastering control is based on Figure 5 The construction engineering plastering control target calibration part positioning equipment shown in the figure. Figure 6 As shown in FIG, the positioning method of the target calibration part for plastering control in construction engineering includes:

[0097] Step S201: A target plastering control target point filter for selecting a target plastering control target point from a plurality of plastering control target points is displayed through a display (belonging to the output device 44). After the target plastering control target point filter is operated through the input device 43 to filter out the target plastering control target point, the plastering control target point positioning information and the plastering control target point calibration part thickness information corresponding to the target plastering control target point are used as the plastering control target information.

[0098] Since multiple plastering control target calibration pieces are often required on existing walls to be plastered, and since a three-dimensional optical scanner can scan all existing walls to be plastered (usually four) in a room at a time, the plastering control target information generated by the construction engineering plastering control target information generation device 3 often contains plastering control target location information and plastering control target calibration piece thickness information corresponding to each of the multiple plastering control targets. Therefore, step S201 uses the target plastering control target filter software to first select the target plastering control target, so that the specific plastering control target calibration piece can be cut and positioned.

[0099] Step S202: Obtain the real-time position information of the plastering control target information (the plastering control target information here specifically refers to the plastering control target positioning information and the plastering control target calibration part thickness information corresponding to the target plastering control target) and the plastering control target positioning device (the plastering control target positioning device here is the construction project plastering control target calibration part positioning device 4).

[0100] Step S203: Compare the real-time position information with the plastering control target positioning information, and determine whether the real-time position of the plastering control target positioning device meets the requirements of the plastering control target positioning information based on the comparison result; when it is determined that the real-time position of the plastering control target positioning device meets the requirements of the plastering control target positioning information, a notification of successful positioning of the plastering control target positioning device is generated and provided to the operator; when it is determined that the real-time position of the plastering control target positioning device does not meet the requirements of the plastering control target positioning information, a notification of movement instruction of the plastering control target positioning device is generated and provided to the operator.

[0101] In step S203, in order to facilitate the operator's operation, the first display information as a notification of successful positioning of the plastering control target positioning device and the second display information as a notification of movement instruction of the plastering control target positioning device are respectively displayed through the display (belonging to the output device 44).

[0102] The second display information may include a first arrow for indicating a specific horizontal upward direction in which the plastering control target positioning device is to be moved on the already built wall to be plastered, a first numerical value for indicating a distance to be moved along the first arrow direction on the already built wall to be plastered, a second arrow for indicating a specific vertical upward direction in which the plastering control target positioning device is to be moved on the already built wall to be plastered, and a second numerical value for indicating a distance to be moved along the second arrow direction on the already built wall to be plastered. In this way, the operator can be intuitively provided with a notification of movement instruction of the plastering control target positioning device.

[0103] In addition, after the first display information as a notification of successful positioning of the plastering control target positioning device is displayed on the display, a cutting start switch can also be generated or activated on the display, and by responding to the operator's operation of the cutting start switch using the input device 43, a cutting instruction is issued to the plastering control target calibration part cutting device 6.

[0104] In an optional embodiment, the plastering control target calibration piece cutting device 6 is designed as a rectangular box structure (see Figure 10 As shown), a bar material insertion port for cutting is provided on the top surface. The bar material for cutting can be made of a material such as plastic that is easy to cut and has a certain strength to maintain its own shape. The diameter of the bar material for cutting is just large enough to be inserted into the bar material insertion port for cutting ( Figure 10 The white elongated object on the plastering control target calibration piece cutting device 6 is the rod to be cut). An outlet for cut rods (i.e., the plastering control target calibration piece) is provided on one side of the rectangular box structure, which is used to discharge the plastering control target calibration piece cut from the rod to be cut from the rectangular box structure. The feeding mechanism is located in the rectangular box structure, and specifically, a piston-type reciprocating motion mechanism can be used to support the lower end of the rod to be cut. The position of the piston rod of the piston-type reciprocating motion mechanism is controlled by the cutting length control mechanism. When the piston rod of the piston-type reciprocating motion mechanism moves downward, the rod to be cut moves downward along the axis of the rod insertion port to be cut. The cutting mechanism uses a saw blade, and the direction of the saw blade is perpendicular to the rod to be cut. When the rod to be cut moves downward to the set position, the saw blade can cut into the rod to be cut so that the rod to be cut is cut. At this time, the plastering control target calibration piece will fall out of the outlet.

[0105] The above describes the relevant contents of this application. Based on these descriptions, a person of ordinary skill in the art will be able to implement this application. Based on the above contents of this specification, all other embodiments obtained by a person of ordinary skill in the art without making any creative efforts should fall within the scope of this application.
