Description

Technical Field

[0001] The present application relates to the field of metal sheet fillet welding technology, and in particular to an automatic sheet metal fillet welding device and a control system. Background Art

[0002] Fillet welding is a basic and key connection technology in the metal sheet processing industry and the metal manufacturing industry. Two metal sheets are connected at a right angle to form a stable and reliable overall structure. The application of fillet welding has penetrated into all walks of life and plays an important role.

[0003] The fillet welding of metal sheets is achieved by forming a weld seam at the edge junction of two metal parts, and most of the welding operations are manually performed by welders. Nowadays, there are already automatic fillet welding devices, which greatly improve the production efficiency of metal sheet welded parts. Specifically, technicians pre-set the welding parameters of the welding machine, including welding current, voltage, speed, etc. During the fillet welding process, the automatic welding machine fixes the welding sheet on the welding table, and the welding torch feeds to complete the welding.

[0004] However, most of the existing automatic fillet welding devices can only weld two metal sheets, and only right-angle welding of two sheets can be performed. In view of the above related technologies, the inventor believes that improvements can be made to the existing automatic fillet welding devices from the perspective of the structural composition of the automatic welding device, increasing the number of welded metal sheets and the welding angles, and improving the flexibility of the automatic welding device.

[0005] In order to enhance the flexibility of the automatic welding device, the present invention provides an automatic sheet metal fillet welding device and a control system.

[0006] On the one hand, an automatic sheet metal fillet welding device provided by the present invention adopts the following technical solutions:

[0007] An automatic sheet metal fillet welding device and a control system, including a machine shell, a welding table is arranged at the center of the machine shell, and a plurality of welding torches are arranged above the welding table corresponding to the machine shell. The device further includes:

[0008] Two bottom frame plates are arranged in parallel. The edges on the opposite sides of the two bottom frame plates are hinged to the surface of the welding table, and the edges on the facing sides are free sides. A driving component is arranged below the welding table for the two bottom frame plates to drive the bottom frame plates to rotate;

[0009] The first fixing components are horizontally arranged, and two are symmetrically arranged above the two opposite sides of the welding table. One end of the two first fixing components close to the bottom frame plate is inclined; the angles of the inclined parts of the two first fixing components change;

[0010] The second fixing component is vertically arranged above the welding table;

[0011] Side support components are arranged on the opposite sides of the welding table corresponding to the two chassis plates for supporting the chassis plates.

[0012] By adopting the above technical solutions, the casing is the housing structure of the corner welding device, and a chamber for welding work is provided inside the casing. The welding table is arranged in the chamber. The welding table is the main load-bearing structure during the metal sheet welding process. The first fixing component, the second fixing component, and the side support components on the welding table are the main fixing parts for the metal sheet before welding. The welding torch is aligned with the weld between the metal sheets, and the welding torch feeds towards the weld during welding to complete the welding.

[0013] Specifically, the first fixing component is horizontally arranged for fixing the metal sheet obliquely placed on the chassis plate. The initial state of the chassis plate should be in contact with the surface of the welding table. Before the welding work starts, the two chassis plates should rotate to an inclined state around the opposite edges. The included angle between the two chassis plates is the preset welding angle of the two metal sheets. The welder should place the surface of the metal sheet on the inclined surfaces of the two chassis plates in advance. The top edges of the two metal sheets in the inclined state are in contact to form a weld. The first fixing component operates, and the angle-changing component at its end changes the angle to fit the metal sheet on the chassis plate surface, applies force and fixes it, so that the metal sheet is pressed tightly against the chassis plate surface to complete the fixing.

[0014] In the above process, the fixing of the metal sheet depends on the first fixing component, and the fixing of the inclined state of the chassis plate depends on the side support component. The connection mode between the side support component and the chassis plate is horizontal hinge to support the rotation of the chassis plate in the vertical plane. The side support component also needs to have a sliding effect. During the rotation of the chassis plate with a fixed plate surface size, the side support component synchronously slides horizontally along the welding table and is fixed at the preset position after reaching the preset position to fix the chassis plate.

[0015] Thus, with the support of the side support component, by changing the inclination angle of the chassis plate, the two chassis plates are synchronously rotated until the angle between the two chassis plate surfaces is the preset angle. After the technician places the metal sheets on the two chassis plates, the included angle between the two metal sheets is the included angle between the chassis plate surfaces.

[0016] In addition to the traditional two-plate welding, the above solution can also achieve three-plate welding. During the three-plate welding process, two of the plates are respectively placed obliquely on the chassis plate, and the two metal sheets form a preset included angle. The third metal sheet is set vertically, and the bottom edge abuts against the welds of the two metal sheets. The third metal sheet is fixed by the second fixing component arranged above the welding table to maintain a stable vertical state, and the bottom edge of the third metal sheet abuts against the two metal sheets.

[0017] It should be noted that during the three-plate welding process, the vertically arranged third plate is used as the reference plate. Regardless of the angle between the three plates, in the above solution, the third metal plate remains vertical, and the angles of the two chassis plates are changed to change the included angle of the other two metal plates;

[0018] In the above solution, the angles between the two chassis plates and the horizontal plane may be different.

[0019] Optionally, the first fixing component includes:

[0020] A first slider, vertically slidably connected to the inner wall of the casing, and a horizontally arranged first fixing rod is formed on the first slider;

[0021] A first fixing plate, hinged to one end of the first fixing rod away from the first slider, and its hinge axis is parallel to the hinge axis on one side of the chassis plate.

[0022] By adopting the above technical solution, the first fixing component has the functions of sliding, telescoping, and angle changing, and is used to fix the metal plate placed at a preset angle on the inclined chassis plate. The fixed end of the first fixing component needs to change its own angle according to the inclination angle of the chassis plate to make it parallel to the plate surface of the chassis plate; the first fixing component also needs to change its own height by vertical sliding to correspond to the height of the chassis plate at different inclination angles;

[0023] Specifically, the horizontally arranged first fixing rod is the main framework of the first fixing component. The length direction of the first fixing rod is perpendicular to the length direction of the chassis plate, that is, perpendicular to the placement direction of the metal plate on the chassis plate. One end of the first fixing rod close to the inner wall of the casing is fixedly connected with the slider, and the slider slides vertically along the inner wall of the casing. The first fixing plate hinged to one end of the first fixing rod close to the chassis plate can rotate freely in the vertical plane;

[0024] Thus, in the initial state, due to the action of gravity, the plate surface of the first fixing plate is horizontal, and the rod body length of the first fixing rod is the preset length, so that the plate surface of the first fixing plate extends above the inclined chassis plate. Then, the first slider slides vertically downward along the inner wall of the casing, causing the first fixing plate to move downward and abut against the chassis plate. The first slider continues to move downward, and the plate surface of the chassis plate hinged to the first fixing rod gradually fits the metal plate fixed on the inclined chassis plate;

[0025] In addition, there may be another fixing method for the first fixing plate in the above solution. The first fixing rod is provided with a clamping structure corresponding to the first fixing plate, so that in the free state, due to the limitation of the clamping structure, the first fixing plate cannot become horizontal but is in an inclined state. Thus, after the first fixing plate feeds, its plate surface directly abuts against the metal plate on the chassis plate;

[0026] Regardless of the above-mentioned abutting manner, after the metal plate abuts against the first fixing plate, the two first fixing rods apply horizontal forces towards each other to make the metal plate continuously abut against the bottom frame plate, thereby completing the fixation.

[0027] Optionally, the second fixing component includes:

[0028] Two second sliders are arranged at the same height above the bottom frame plate, and the two second sliders are horizontally slidably connected to the inner wall of the housing;

[0029] The second fixing rod has a length direction parallel to the length direction of the base plate. A plurality of second fixing plates are distributed on the rod body of the second fixing rod. The second fixing plates have vertical plate surfaces. The second fixing plates on the two second fixing rods are arranged on opposite sides of the second fixing rod.

[0030] By adopting the above technical solution, the second fixing assembly is applicable to the case of three-plate welding in the above solution. In addition to the metal plates on the two bottom frame plates, the technicians place the bottom edge of a vertically arranged metal plate on the weld of the metal plates on the two bottom frame plates, and the cross section forms a triangular structure. The second fixing assembly is used to fix the vertically arranged metal plate;

[0031] Specifically, the height of the two second sliding blocks is higher than the height of the base plate. The second sliding blocks slide toward and away from each other, driving the second fixed rod to maintain a horizontal position and change the position of the rod body. The two second fixed rods are provided with multiple second fixed plates facing each other, and the second fixed plates are distributed along the length direction of the second fixed rods, that is, along the length direction of the base plate. When the two second sliding blocks slide toward each other, the two second fixed plates press against the third metal plate placed by the technician.

[0032] Optionally, the side support assembly includes:

[0033] A side plate, the length direction of which is parallel to the length direction of the base plate, and the side edge of the side plate close to the base plate is hinged to the base plate;

[0034] The side sliding blocks are slidably connected to the welding platform, are arranged at two ends of each side plate, and are hingedly arranged at two ends of an edge of a side of the bottom frame plate away from the bottom frame plate.

[0035] By adopting the above technical solution, the side support components are arranged on the opposite sides of the two bottom frame plates to support the two bottom frame plates. The opposite sides of the two bottom frame plates are respectively hinged to the side plates, enabling the plate surfaces of the two bottom frame plates to freely rotate around the hinged sides, changing the inclination angle of the plate surfaces. The two side plates rotate synchronously while the bottom frame plates rotate, changing from a horizontal angle to an inclined state. At the same time, the side sliders at both ends of the opposite sides of the two side plates slide towards each other when the side plates rotate, structurally supporting the rotation of the side plates and the bottom frame plates when the plate surface sizes are fixed. However, in actual application, a fixing component for fixing the side sliders needs to be arranged on the welding table.

[0036] In summary, the significance of the side plate arrangement in the above solution is to support the changing height requirements when the bottom frame plate rotates. Before the start of the welding process, for metal plates with a plate surface width wider than the bottom frame plate size, the inclination of the bottom frame plate alone cannot effectively support the welding of the metal plates. Therefore, it is necessary to raise the height of the bottom frame plate.

[0037] Optionally, a gap is provided between the opposite side edges of the two bottom frame plates.

[0038] By adopting the above technical solution, a gap is provided between the opposite side edges of the two bottom frame plates in the horizontal state. After rotation, the gap between the top side edges of the two bottom frame plates increases, providing the space required for splicing and welding the welds when the technicians form welds at the top ends of the two metal plates, improving the operability of welding.

[0039] On the contrary, if the two bottom frame plates are closely attached to each other, it will increase the wear degree of the opposite side edges of the two bottom frame plates and reduce the service life of the bottom frame plates.

[0040] Optionally, a slag trough is provided on the welding table surface and penetrates below the gap between the two bottom frame plates.

[0041] By adopting the above technical solution, before the welding of the metal plates, due to processes such as grinding and extrusion, metal slag adheres to their surfaces. The gap between the two bottom frame plates and the slag trough below the weld of the metal plates are in a vertical plane. When the top ends of the above two metal plates are abutted to form a weld, the slag trough provides a channel for the weld to fall to the welding table, improving the welding quality.

[0042] On the other hand, a control system of an automatic sheet metal corner welding device provided by the present invention adopts the following technical solution:

[0043] A control system of an automatic sheet metal corner welding device, characterized in that it includes a central processing module, a front-end control module, a data acquisition module, and a display module.

[0044] The data acquisition module collects the operation information of the first fixing component, the second fixing component, and the side support component, including the voltage and current of the welding torch and the air pressure and air flow rate of the air gun; the data acquisition module is connected to the central processing module and sends the operation information of the fillet welding device to the central processing module;

[0045] The central processing module internally stores instruction files and data files. The central processing module receives the data information from the data acquisition module, calculates data results by bringing in relevant data files, and generates corresponding instruction signals by running relevant instruction files; the central processing module sends the data results to the display module and sends the instruction signals to the front-end control module;

[0046] The front-end control module receives the instruction signals from the central processing module, specifically executes them, and controls the operation of the first fixing component, the second fixing component, and the side support component;

[0047] The display module is connected to the central processing module and displays the data results and instruction signals of the central processing module.

[0048] Optionally, it further includes a data writing module and a wireless module;

[0049] The data writing module is connected to the central processing module and provides channels for the operation data and operation state adjustment of the fillet welding device; technicians input instructions through the data writing module to overwrite the original instructions of the central processing module, and the front-end control module preferentially executes the writing instructions of the data writing module;

[0050] The wireless module is connected to the data writing module and the central processing module and is used for the remote transmission of data and instructions of the data writing module and the central processing module.

[0051] By adopting the above technical solutions, the central processing module, the front-end control module, the data acquisition module, the display module, the wireless module, and the data writing module jointly form the control system of the automatic fillet welding device;

[0052] Among them, the central processing module has the functions of data calculation and instruction sending and is the central control module in this control system. The data acquisition module is mainly used for collecting the operation status and information of each active component in the automatic fillet welding equipment, sending the collected data information to the central processing module, where the central processing module processes, analyzes, and calculates, forms instruction signals according to the operation status of each component in the device, and sends them to the front-end control module. The front-end control module specifically executes the generated instructions of the central processing module to control the operation of active components inside the device such as the welding torch, welding circuit, and air gun;

[0053] Thus, the data acquisition module, the central processing module, and the front-end control module together form a control feedback system to realize the feedback loop of data acquisition, instruction generation, and control operation;

[0054] In addition to the instructions generated by the central processing module, the execution instructions of the front-end control module can also be written by the data writing module. In the above solution, the instruction priority of the data writing module is higher than that of the central processing module, and the front-end control module preferentially executes the instructions of the data writing module; during the above instruction writing process, the wireless module supports remote writing of the data writing module;

[0055] During the welding process of the above metal plate, the display module displays the data calculation results and instruction generation results of the central processing module and the control operation status of the front-end control module, enabling technicians to immediately understand the operation status of the automatic fillet welding equipment.

[0056] In summary, the present application includes at least one of the following beneficial technical effects:

[0057] 1. Through the design of the chassis plate and the drive assembly, precise rotation of the plate during the welding process is achieved, significantly improving the accuracy and efficiency of fillet welding operations, meeting the welding of metal plates under various angle requirements, not limited to right-angle welding;

[0058] 2. The inclined setting of the first fixing component and its angle change enable different specifications of plates to be fixed more accurately, enhancing the adaptability and flexibility of the device; the setting of the second fixing component can stabilize the plate in the vertical direction, ensuring that the position of the plate is more stable during the welding process, further improving the welding quality;

[0059] 3. The data acquisition module real-time collects information such as the voltage and current of the welding torch and the air pressure and air flow rate of the air gun. The central processing module automatically optimizes the welding parameters based on the collected information, significantly improving the welding accuracy and efficiency; the data writing module can remotely update the instructions in the central processing module, enabling the front-end control module to preferentially execute the new instructions, enhancing the flexibility and response speed of the system.

[0066] The following further Figures 1-5 describes the present application in detail with reference to the appended

[0067] On the one hand, the embodiments of the present application disclose an automatic sheet metal corner welding device. Referring to Figure 1 , an automatic sheet metal corner welding device includes a machine shell 1, an electric control box is arranged on the side wall of the machine shell 1, and a welding bin 11 is opened in the machine shell 1; a welding table 2 is formed on the inner wall of the machine shell 1 corresponding to the welding bin 11, and the table top of the welding table 2 is horizontally arranged. In this embodiment, the main component part of the corner welding device is arranged on the welding table 2; on the inner top wall of the welding bin 11, a welding torch 12 is arranged on both opposite sides of the welding table 2, and the ends of the welding torches 12 face each other and extend to a part above the welding table 2 close to the table top of the welding table 2, which is the main welding structure.

[0068] Referring to Figure 2 and Figure 3 , the welding table 2 is in a rectangular block shape, and side chutes 23 are horizontally opened at the four corner parts of the table top. Side sliders 231 are slidably connected in the side chutes 23. In this embodiment, no active driving structure is arranged in the side chutes 23, and the side sliders 231 are used as passive sliding parts; in order to fix the side sliders 231, the inner bottom wall of the side chutes 23 is composed of electromagnets. When the side sliders 231 slide to the corresponding positions, the electromagnets are energized to adsorb and fix the side sliders 231 at the corresponding positions; therefore, in this embodiment, the side sliders 231 need to be composed of magnetic materials, preferably stainless steel.

[0069] Referring to Figure 2 and Figure 3, on the welding table 2, two side plates 232 are arranged in parallel. The two side plates 232 are respectively arranged at the opposite side edges of the welding table 2. The two ends of the opposite side edges of the two side plates 232 extend between the two side sliders 231 at the same side edge of the welding table 2, so that the two ends of the opposite side edges of the two side plates 232 are hinged to the opposite sides of the two side sliders 231. The hinge axis is horizontal. Thus, the side plate 232 can rotate around the hinged side. On the opposite sides of the two side plates 232, a bottom frame plate 3 is hinged respectively. The opposite sides of the two bottom frame plates 3 are free sides, so that the two bottom frame plates 3 can rotate freely around the opposite side edges of the two side plates 232; the bottom frame plate 3 is the main structure for supporting the fillet welding of metal plates; in this embodiment, the plate surface length of the bottom frame plate 3 is equal to the plate surface length of the side plate 232, and the plate surface width of the bottom frame plate 3 is greater than the plate surface width of the side plate 232, ensuring that most of the weight of the metal plate is borne by the bottom frame plate 3 when placed.

[0070] Refer to Figure 2 and Figure 3 , corresponding to the bottom side of the side plate 232 on the welding table 2, a driving groove 31 is opened. A plurality of driving grooves 31 are distributed along the length direction of the bottom frame plate 3. In each driving groove 31, two driving members are arranged as the driving members for the rotation of the bottom frame plate 3 and the side plate 232. The two driving members are distributed along the length direction of the driving groove 31. In this embodiment, the driving member is selected as the electric cylinder 32. The cylinder body of the electric cylinder 32 is hinged to the bottom wall of the driving groove 31, and the piston rod of the electric cylinder 32 is hinged to the bottom side surface of the bottom frame plate 3. Thus, the piston rods of all the electric cylinders 32 corresponding to one bottom frame plate 3 extend synchronously, pushing the bottom frame plate 3 to rotate around the hinged side. When the extending length of the piston rod of the electric cylinder 32 is relatively large, the bottom frame plate 3 pulls the side plate 232 to rotate, and further drives the side sliders 231 on the opposite sides of the two side plates 232 to slide. Fix the side slider 231, and adjusting the extending length of the piston rod of the electric cylinder 32 can control the included angle of the bottom frame plate 3, that is, the welding included angle of the two metal plates.

[0071] Refer to Figure 2 and Figure 3 , a slag groove 24 is vertically penetrated on the welding table 2. The slag groove 24 is opened below the opposite side edges of the two bottom frame plates 3, and is used for the metal slag to fall during welding. The metal slag falls through the slag groove 24 to the bottom of the machine shell 1, avoiding the accumulation of metal slag on the welding table 2. Further, to ensure the smooth falling of the metal slag, a gap is provided between the opposite side edges of the two bottom frame plates 3 in the horizontal state, and as the bottom frame plate 3 rotates upward, the gap between the bottom frame plates 3 increases, reserving enough welding space during welding.

[0072] Refer to Figure 2 and Figure 4, symmetrically provided with screw grooves on the inner walls of the two opposite sides of the welding bin 11, the two screw grooves have the same structure, and one of them is taken as an example; the screw groove is vertically opened, and a screw is rotatably connected in the screw groove, and a motor is arranged above the screw groove corresponding to the inner wall of the welding bin 11 to drive the screw to rotate, and a first slider 211 is penetrated and threadedly connected on the screw, and as the screw rotates, the first slider 211 slides vertically along the screw groove, and a horizontally arranged first fixing rod 212 is horizontally fixedly connected to the first slider 211, and a horizontally arranged driving cylinder is fixedly connected to the end of the first fixing rod 212 away from the first slider 211, and the cylinder body of the first driving cylinder 215 is horizontally arranged, and the piston rod of the first driving cylinder 215 faces the two bottom frame plates 3, and the piston rod end of the first driving cylinder 215 is hinged with the first fixing plate 213, and the hinge axis of the two is horizontally arranged parallel to the length direction of the bottom frame plate 3, so that the first fixing plate 213 can rotate in the vertical plane around the hinge axis. A clamping block 214 is formed at the end of the piston rod of the driving cylinder, or in the present embodiment, the clamping block 214 is formed on the first fixed plate 213. When only gravity acts, the surface of the first fixed plate 213 is abutted against the clamping block 214 and the main part of the driving cylinder piston rod, thereby preventing the surface of the first fixed plate 213 from becoming horizontal due to an unrestricted structure.

[0073] Therefore, when the technician places the metal sheet on the two base plates 3, the first slider 211 slides vertically to a height aligned with the metal sheet on the base plate 3, and the first driving cylinder 215 extends the piston rod, and the first fixed plate 213 abuts the metal sheet. The first driving cylinder 215 keeps the piston rod extended, so that the surface of the first fixed plate 213 is pressed against the surface of the metal sheet to complete the fixation.

[0074] The first fixing plate 213 , the first driving cylinder 215 , the first sliding block 211 , and the first fixing rod 212 constitute a first fixing assembly 21 , which is used to fix the metal plate placed obliquely on the base plate 3 in this embodiment.

[0075] Reference Figure 2, on one of the partition walls of the welding chamber 11 between the partition walls where the first fixing component 21 is provided, a second fixing component 22 is provided. The second fixing component 22 includes a second sliding groove, which is horizontally opened above the two bottom frame plates 3. Two second sliding blocks 223 are slidably connected in the second sliding groove. A second driving cylinder is provided corresponding to each second sliding block 223 in the second sliding groove. The second driving cylinders are arranged facing each other, and the piston rods are extended and retracted to make the two second sliding blocks 223 slide towards and away from each other; a second fixing rod 221 is horizontally arranged on each second sliding block 223 corresponding to the part above the tabletop of the welding table 2. One end of the second fixing rod 221 is fixedly connected to the second sliding block 223. A plurality of vertically arranged second fixing plates 222 are fixedly connected to the opposite sides of the two second fixing rods 221. The plurality of second fixing plates 222 are equally spaced along the length direction of the second fixing rod 221. In this embodiment, the distribution range of the second fixing plates 222 is only limited to above the two bottom frame plates 3, and the second fixing rods 221 correspond to the bottom frame plates 3 one by one.

[0076] Thus, the second fixing plates 222 can slide towards each other. After the technician vertically places the metal plate on the weld of the two metal plates, the two second fixing plates 222 clamp towards each other to achieve fixation.

[0077] The implementation principle of an automated sheet metal corner welding device and control system according to an embodiment of the present application is as follows: After the technician places the metal plate on the two bottom frame plates 3, when the first sliding block 211 slides vertically to align with the metal plate on the bottom frame plate 3 in height, the first driving cylinder 215 extends the piston rod, and the first fixing plate 213 abuts against the metal plate. The first driving cylinder 215 maintains the state of the extended piston rod, so that the plate surface of the first fixing plate 213 tightly abuts against the plate surface of the metal plate to complete the fixation. The second fixing plates 222 can slide towards each other. When performing three-plate welding, after the technician vertically places the metal plate on the weld of the two metal plates, the two second fixing plates 222 clamp towards each other to achieve fixation.

[0078] On the other hand, an embodiment of the present application discloses a control system for an automated sheet metal corner welding device, which is used to control the above-mentioned automated sheet metal corner welding device. Refer to Figure 5, The control system of an automated sheet metal corner welding device includes a central processing module 5, a front-end control module 6, a data acquisition module 81, a display module 7, a data writing module 82, and a wireless module 8. The data acquisition module 81 collects the operation information of the first fixing component 21, the second fixing component 22, and the side support component, including the voltage and current of the welding torch 12 and the air pressure and air flow rate of the air gun, and sends the collected information to the central processing module 5. The central processing module 5 stores instruction files and data files internally, and is generally preferably an electric control component integrated with a machine tool. The central processing module 5 receives the data information from the data acquisition module 81, calculates the data results by bringing in relevant data files, runs relevant instruction files to generate corresponding instruction signals, and controls the front-end control module 6 to execute specifically according to the instructions. The front-end control module 6 is mainly composed of the electric control circuits of the active components in this embodiment, such as the first driving cylinder 215, the second driving cylinder, and the welding torch 12, receives the main control signals from the central processing module 5, and controls the first driving cylinder 215, the second driving cylinder, and the welding torch 12 to operate according to relevant instructions.

[0079] Referring to Figure 5 , The data writing module 82 is connected to the central processing module 5 to provide a channel for the operation data and operation state adjustment of the corner welding device; technicians input instructions through the data writing module 82 to overwrite the original instructions of the central processing module 5, and the front-end control module 6 preferentially executes the written instructions of the data writing module 82.

[0080] Referring to Figure 5 , The wireless module 8 is connected to the data writing module 82 and the central processing module 5, and the data acquisition module 81 and the central processing module 5, and is used for remote transceiver of data and instructions between the data acquisition module 81, the data writing module 82, and the central processing module 5.

[0081] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
