[0049] Specifically, the spherical surface detection device for automobile glass in the embodiment of the present application, in use, when the automobile glass 80 is conveyed on the conveying surface of the conveying mechanism 20, when the automobile glass 80 is conveyed to a certain position by the conveying mechanism 20, the positioning mechanism 30 performs positioning operation on the automobile glass 80 to avoid the automobile glass 80 from continuously moving forward, after the positioning of the automobile glass 80 is completed, the control device sends an instruction to start the moving mechanism 40, the moving mechanism 40 drives the distance measuring sensor 50 to move above the automobile glass 80 according to a preset path, at the same time, the distance measuring sensor 50 transmits the distance information between the surface of the automobile glass 80 and the detection end of the distance measuring sensor 50 to the control device in real time, the control device calculates and analyzes the feedback distance information to obtain whether the spherical surface value of the automobile glass 80 meets the requirements, thereby realizing the automatic detection of the spherical surface detection of the automobile glass 80, the detection efficiency is high, in particular, the distance measuring sensor 50 is adopted to obtain the distance information, and the control device is adopted to analyze and calculate, which eliminates the manual reading and manual detection operation, the accuracy of the distance information is high, the error is small, at the same time, the detection efficiency of the automobile glass 80 can be effectively improved, and the safety hidden danger existing in the manual detection can be solved, the operation safety is high.

[0050] Further, it needs to be explained that, referring to Figure 1 and Figure 3As shown, in the automobile glass 80 spherical surface detection, generally need to take three detection curves 81 on the surface of the automobile glass 80 along the longitudinal direction and interval, and then take three specific points 82 on a detection curve 81, then measure the distance value of each specific point 82 to the straight line 84 determined by the two edge points of the corresponding detection curve 81, compare the distance value with the standard distance value, to determine whether the detected automobile glass 80 meets the requirements, but when using the automobile glass spherical surface detection device in the embodiment for detection, the distance measuring sensor 50 moves along the three detection curves 81 in turn, wherein, in the process of the distance measuring sensor 50 moving along the detection curve 81, the distance measuring sensor 50 obtains the distance information of a plurality of points on the detection curve 81 to the distance measuring sensor 50 and feeds back to the control device, at the same time, the moving mechanism 40 feeds back the distance information of the points to the control device in real time, at the same time, the moving mechanism feeds back the position information of the points to the control device, the control device fits a continuous virtual curve 86 according to the distance information and position information of a plurality of points, then calculates and analyzes a straight line 84 tangent to both ends of the virtual curve 86, then takes a plurality of detection points 83 on the straight line 84 at equal intervals (for example: the distance between the detection point 83 and the intersection between the straight line 84 and the detection curve 81 is 100mm, 200mm, 300mm or 400mm), then, the perpendicular line 85 perpendicular to the straight line 84 intersects with the virtual curve 86, finally, the length H of the perpendicular line 85 between the straight line 84 and the virtual curve 86 is calculated, so as to obtain the distance value of the detection point 83 to the automobile glass 80, repeat the above steps to detect each detection point 83 on each virtual curve 86 in turn, and then compare the obtained distance value with the corresponding standard distance value in turn, if the measured distance value is within the allowable error range of the standard distance value, it can be judged that the spherical surface of the automobile glass 80 meets the requirements; otherwise.

[0051] The automobile glass spherical surface detection device of the embodiment, the distance measuring sensor 50 and the moving mechanism 40 are coordinated by the control device, so as to obtain three virtual curves 86 on the automobile glass 80 which can simulate the detection curve 81 on the actual automobile glass 80, then the control device calculates and analyzes the virtual curve 86 to obtain the spherical surface value, compared with the existing method of only detecting a few specific points 82 on the automobile glass 80, the detection result is more accurate, in addition, the automobile glass spherical surface detection device can realize real-time, online and continuous precise measurement and automatic detection of the spherical surface of the automobile glass 80, so as to quickly adapt to the production rhythm of the automobile glass 80, and the production efficiency of the automobile glass 80 will not be affected, and the defective products can be returned to the furnace in time, greatly reducing the labor intensity of the operator.

[0052] In the embodiment, the control device can be integrated by an electric control component, an information processing center and a data processing center. The control device can also be a PLC controller or a computer.

[0053] In the embodiment, the bottom of the rack 10 is also provided with a liftable supporting leg 11 to facilitate the height adjustment of the automobile glass spherical surface detection device and meet different use requirements.

[0054] In another embodiment of the present application, the ranging sensor 50 of the automobile glass spherical surface detection device is a laser ranging sensor. Specifically, when the laser ranging sensor is used to measure the distance between the surface of the automobile glass 80 and the laser ranging sensor, the laser ranging sensor does not need to be in contact with the automobile glass 80, thereby avoiding the direct contact of the personnel with the high-temperature automobile glass 80 on the conveying mechanism 20, improving the safety of the detection, and at the same time, the detection accuracy of the laser ranging sensor is high, effectively improving the detection accuracy of the automobile glass spherical surface detection device.

[0055] In another embodiment of the present application, as shown in Figure 1 、 Figure 2 and Figure 3 , the moving mechanism 40 of the automobile glass spherical surface detection device is a mechanical hand, so that the running speed of the ranging sensor 50 is more stable and faster. The automobile glass spherical surface detection device further comprises a bracket for mounting the mechanical hand. The mechanical hand is composed of an X-axis linear module 42, a Y-axis linear module 43 and a Z-axis linear module 44. The cooperation of the X-axis linear module 42, the Y-axis linear module 43 and the Z-axis linear module 44 can automatically control the ranging sensor 50 to move in the X-axis, Y-axis and Z-axis directions, so that the ranging sensor 50 can detect any point on the automobile glass, improving the versatility of the automobile glass spherical surface detection device.

[0056] Further, it should be noted that the directions of the X-axis, Y-axis and Z-axis are shown in Figure 1 and Figure 2 , wherein the Y-axis is the same as the conveying direction of the conveying mechanism 20.

[0057] The automobile glass spherical surface detection device in the embodiment can automatically obtain the oven trolley model of the automobile glass 80 by combining the control device with the oven trolley number of the automobile glass 80, that is, obtaining the model of the automobile glass 80, so that the ranging sensor 50 and the corresponding standard distance information of the automobile glass 80 are automatically switched, to achieve the requirements of the rapid and accurate detection of different models of the automobile glass 80 and the quick switching detection of different models of the automobile glass 80, and the production rhythm of the automobile glass 80 is not affected.

[0058] In another embodiment of the present application, as shown in Figure 1 ,Figure 2 and Figure 4 As shown, the positioning mechanism 30 of the provided automotive glass spherical surface detection device includes a first positioning component 31. The first positioning component 31 includes a motor (not shown), a synchronous belt 312, two synchronous pulleys 313, and two first positioning posts 314. The two synchronous pulleys 313 are located on opposite sides of the conveying mechanism 20. The synchronous belt 312 is wound around the two synchronous pulleys 313. The output shaft of the motor is connected to one of the synchronous pulleys 313 and is used to drive the synchronous pulley 313 to rotate. The two first positioning posts 314 are located on opposite sides of the conveying mechanism 20 and are arranged vertically. The two first positioning posts 314 are fixedly installed on opposite sections of the synchronous belt 312. Specifically, the motor starts and drives the synchronous pulley 313 to rotate, which in turn drives the synchronous belt 312 wound around the synchronous pulley 313 to move. Since the two first positioning posts 314 are respectively located on opposite sides of the conveying mechanism 20 and are arranged vertically, and the two first positioning posts 314 are respectively fixedly installed on opposite sections of the synchronous belt 312, when the synchronous pulley 313 rotates, it can drive the two first positioning posts 314 to move closer or further away from each other. When the two first positioning posts 314 are closer, they clamp the car glass 80 left and right, realizing the left and right positioning of the car glass 80. After the inspection is completed, when the two first positioning posts 314 are further away from each other, the car glass 80 is released to facilitate the subsequent processing of the car glass 80.

[0059] Furthermore, it should be noted that the front, rear, left and right sides of the frame 10 are determined according to the conveying direction of the conveying mechanism 20, and the automotive glass 80 is conveyed forward on the conveying mechanism 20.

[0060] In another embodiment of the invention, see [reference] Figure 1 , Figure 2 and Figure 4 As shown, the first positioning component 31 of the provided automotive glass spherical inspection device also includes a mounting rod 311 and a lifting drive (not shown). The driving end of the lifting drive is connected to the mounting rod 311 and is used to drive the mounting rod 311 to move vertically. Two synchronous wheels 313 are respectively installed at both ends of the mounting rod 311. Specifically, the lifting drive drives the mounting rod 311 to move vertically, thereby driving the first positioning component 31 installed on the mounting rod 311 to move vertically. When the automotive glass 80 is conveyed to a certain position on the conveying surface of the conveying mechanism 20, the lifting drive drives the first positioning component 31 to move upward until the two first positioning posts 314 extend out of the conveying surface, and then the synchronous wheels 313 are activated to clamp the automotive glass 80. After the inspection is completed, the lifting drive drives the first positioning component 31 to move downward until the first positioning posts 314 are completely moved below the conveying surface. This can prevent the automotive glass 80 from contacting the first positioning posts 314 and causing damage to the automotive glass 80.

[0061] Further, the fixed rod 644 is provided with two sliding rails 315, the two first positioning columns 314 are each provided with a sliding block 316, the two sliding blocks 316 are respectively in sliding connection with the two sliding rails 315, and the second positioning column 323 is guided by the sliding rail 315 and the sliding block 316, so that the relative movement of the two first positioning columns 314 is more stable and reliable, the positioning of the automobile glass 80 is more accurate, and the detection precision is high.

[0062] Preferably, the lifting driving member can be a vertical electric cylinder, and the electric cylinder is electrically connected with the control device, so as to realize automatic operation of the left and right positioning of the automobile glass 80, improve the detection efficiency and the detection precision.

[0063] In another embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 4 , the positioning mechanism 30 of the automobile glass spherical surface detection device further comprises a second positioning assembly 32, the second positioning assembly 32 comprises a lifting cylinder 321, a connecting plate 322 and a second positioning column 323, the cylinder body of the lifting cylinder 321 is installed on the rack 10, the piston rod of the lifting cylinder 321 is connected with the connecting plate 322 and is used to drive the connecting plate 322 to move vertically, the second positioning column 323 is vertically arranged, and the second positioning column 323 is installed on the connecting plate 322 and located at the discharging position of the conveying mechanism 20. Specifically, when the automobile glass 80 reaches a certain position under the conveying of the conveying mechanism 20, the lifting cylinder 321 is started, the piston rod of the lifting cylinder 321 drives the connecting plate 322 to move upwards, so that the second positioning column 323 extends out of the conveying surface, so that the second positioning column 323 blocks the automobile glass 80 on the conveying mechanism 20 from moving forward, thereby realizing the front positioning of the automobile glass 80.

[0064] Further, the number of the second positioning columns 323 is two, three or more than three, each second positioning column 323 is installed on the connecting plate 322 in sequence and at intervals along the X-axis direction, and the plurality of second positioning columns 323 are in contact with the edges of the automobile glass 80, so as to block the automobile glass 80 from moving forward, thereby avoiding the problem of inclination of the automobile glass 80 and ensuring the accuracy of the detection of the distance measuring sensor 50.

[0065] Preferably, the lifting cylinder 321 can also be a vertical electric cylinder, and the electric cylinder is electrically connected with the control device, so as to realize automatic operation of the front positioning of the automobile glass 80, improve the detection efficiency and the detection precision.

[0066] In another embodiment of the present application, as shown in Figure 2 , Figure 4 and Figure 5As shown, the provided automobile glass spherical surface detection device further comprises a jacking mechanism 60 for jacking up the automobile glass 80. Specifically, after the automobile glass is conveyed to a certain position, the jacking mechanism jacks up the automobile glass, the conveying mechanism 20 is separated from the automobile glass 80, and the conveying force of the conveying mechanism 20 no longer acts on the automobile glass 80. Therefore, the automobile glass 80 is stable during the detection process and does not move or shake, effectively reducing detection errors and improving the accuracy of the detection results.

[0067] In another embodiment of the present application, as shown in Figure 2 、 Figure 4 and Figure 5 , the jacking mechanism 60 of the provided automobile glass spherical surface detection device comprises a linear driving member 61, a connecting rod 62, a rotating rod 63, a lifting assembly 64 and two jacking rods 65. The linear driving member 61 is installed on the rack 10, the driving end of the linear driving member 61 is hingedly connected to one end of the connecting rod 62, the other end of the connecting rod 62 is fixedly connected to the rotating rod 63, the connecting rod 62 is perpendicular to the rotating rod 63, the rotating rod 63 is rotatably connected to the rack 10, and the rotating rod 63 is connected to the lifting assembly 64 and is used to drive the lifting assembly 64. The two jacking rods 65 are respectively located on both sides of the conveying mechanism 20 and are arranged in extension along the conveying direction of the conveying mechanism 20. Both of the two jacking rods 65 are connected to the driving end of the lifting assembly 64. Specifically, the driving end of the linear driving member 61 is in telescopic motion, the driving end of the linear driving member 61 drives the connecting rod 62 to swing, the connecting rod 62 drives the rotating rod 63 to rotate, the rotating rod 63 drives the lifting assembly 64 to drive the two jacking rods 65 to move upward at the same time, and the two jacking rods 65 jack up the automobile glass 80 on the conveying mechanism 20, so as to separate the automobile glass 80 from the conveying surface of the conveying mechanism 20. In this way, the conveying force of the conveying mechanism 20 no longer acts on the automobile glass 80, so that the automobile glass 80 is stable during the detection process and does not move or shake, effectively reducing detection errors and improving the accuracy of the detection results. When the detection is completed, the driving end of the linear driving member 61 is reset, the jacking rods 65 are retracted below the conveying surface, and the automobile glass 80 is placed on the conveying surface of the conveying mechanism 20. The conveying mechanism 20 conveys the automobile glass 80 to the subsequent processing equipment, realizing the automatic unloading of the automobile glass 80.

[0068] In another embodiment of the present application, as shown in Figure 2 、 Figure 4 and Figure 5As shown, the provided automobile glass spherical surface detection device has two lifting assemblies 64, which are respectively located on the two sides of the conveying mechanism 20. Each lifting assembly 64 includes a first L-shaped plate 641, a pull rod 642, a second L-shaped plate 643, and a fixed rod 644. The bent part of the first L-shaped plate 641 is fixedly connected with the end of the rotating rod 63, and the bent part of the second L-shaped plate 643 is rotatably connected with the rack 10.

The fixed rod 644 and the pull rod 642 are parallel and spaced apart. The two ends of the pull rod 642 are respectively hingedly connected with one end of the first L-shaped plate 641 and one end of the second L-shaped plate 643. The two ends of the fixed rod 644 are respectively hingedly connected with the other end of the first L-shaped plate 641 and the other end of the second L-shaped plate 643. Two jacking rods 65 are respectively installed on the two fixed rods 644. Specifically, the rotating rod 63 rotates and drives the first L-shaped plate 641 to rotate, and then the two ends of the first L-shaped plate 641 swing up and down. Since the two ends of the first L-shaped plate 641 are connected with the two ends of the second L-shaped plate 643 through the pull rod 642 and the fixed rod 644, the pull rod 642 and the fixed rod 644 will move up and down during the rotation of the first L-shaped plate 641. The fixed rod 644 drives the jacking rod 65 connected thereto to move up and down, thereby achieving the lifting and lowering of the automobile glass 80. When the jacking rod lifts the automobile glass 80, the automobile glass 80 is separated from the conveying surface of the conveying mechanism 20, so that the conveying force of the conveying mechanism 20 no longer acts on the automobile glass 80. Therefore, the automobile glass 80 is stable during detection and does not move or shake, effectively reducing detection errors and improving the accuracy of detection results. When the detection is completed, the jacking rod is reset and retracted below the conveying surface, and the automobile glass 80 is placed on the conveying surface of the conveying mechanism 20, facilitating subsequent processing of the detected automobile glass 80.

[0069] Further, in combination with Figure 6 As shown, the two jacking rods 65 are located on the left and right sides of the rack 10, and then the two jacking rods 65 respectively lift the left and right sides of the automobile glass 80, so that the automobile glass 80 is stably supported after being lifted. At the same time, the two jacking rods 65, the two pull rods 642, the two first L-shaped plates 641, and the two second L-shaped plates 643 are respectively located on the two sides of the rack 10 and symmetrically arranged. Therefore, after the linear driving member 61 is driven, the two jacking rods 65 move uniformly, so that the automobile glass 80 can be stably lifted, preventing the automobile glass 80 from being tilted and improving the detection accuracy of the automobile glass 80.

[0070] Further, the jacking mechanism 60 further comprises a first cross rod 66, the first cross rod 66 is rotatably installed on the rack 10, and the two ends of the first cross rod 66 are fixedly connected with the two ends of the two second L-shaped plates respectively, so that the rotation consistency of the two second L-shaped plates 643 is good and stable, thereby making the automobile glass 80 jacked up and fall smoothly and reliably, and avoiding the automobile glass 80 from being damaged by falling.

[0071] Further, in combination with Figure 6 As shown in the figure, the end portions of the two first L-shaped plates 641 connected with the pull rod 642 are connected through the second cross rod 67, and the end portions of the two second L-shaped plates 643 connected with the pull rod 642 are connected through the third cross rod 68, so that through the connecting action of the second cross rod 67 and the third cross rod 68, the rotation consistency of the two first L-shaped plates 641 and the two second L-shaped plates 643 is good and stable; thereby ensuring that the movement of the two jacking rods 65 has good consistency, and making the jacking up and falling of the automobile glass 80 more stable and reliable.

[0072] Further, in combination with Figure 6 As shown in the figure, the fixed rod 644 is provided with a rubber sleeve 70, and the rubber sleeve 70 is soft in material, so that in the process of contacting with the automobile glass 80, the automobile glass 80 will not be scratched or damaged, and a good protection effect is achieved.

[0073] Further, the rotating rod 63 and the first cross rod 66 are both rotatably installed on the rack 10 through bearings 651 and bearing seats 652.

[0074] Further, the linear driving part 61 can also be an electric cylinder, and the electric cylinder is electrically connected with the control device, thereby realizing automatic operation of lifting the automobile glass 80, and improving detection efficiency and detection accuracy.

[0075] In another embodiment of the present application, referring to Figure 4 , Figure 5 and Figure 6 As shown in the figure, the lifting assembly 64 of the automobile glass spherical surface detection device further comprises a third positioning column 645 and a positioning linear module 646, the positioning linear module 646 is installed on the side surface of the jacking rod 65 and is arranged along the conveying direction of the conveying mechanism 20, the driving end of the positioning linear module 646 is connected with the third positioning column 645, and the third positioning column 645 is vertically arranged. Specifically, the positioning linear module 646 is arranged along the conveying direction of the conveying mechanism 20, and when the third positioning column 645 is driven by the positioning linear module 646 to move forward, i.e. the third positioning column 645 moves towards the first positioning column 314, then the third positioning column 645 and the first positioning column 314 clamp the automobile glass 80 on the conveying mechanism 20 from front to back, thereby realizing the front and back positioning of the automobile glass 80, i.e. realizing the positioning of the automobile glass 80 in the Y-axis direction.

[0076] Further, the first positioning column 314, the second positioning column 323 and the third positioning column 645 are all sleeved with rubber sleeves 70, and the rubber sleeves 70 are soft, so that the edges of the automobile glass 80 are not scratched or damaged during the contact with the automobile glass 80, and good protection is achieved.

[0077] Preferably, the X-axis linear module 42, the Y-axis linear module 43, the Z-axis linear module 44 and the positioning linear module 646 are all the same in structure, and only the spatial positions are different during the specific installation. The X-axis linear module 42, the Y-axis linear module 43, the Z-axis linear module 44 and the positioning linear module 646 all include a housing, a screw rod arranged in the housing and rotating along the length direction, a moving nut threadedly connected to the screw rod, a sliding plate fixedly connected to the moving nut and externally exposed from the housing and serving as a driving end, and a motor arranged in the housing and connected to one end of the screw rod. In this way, the motor rotates to drive the screw rod to rotate, drive the moving nut to move linearly along the X-axis, the Y-axis or the Z-axis, and the distance measuring sensor 50 or the third positioning rod fixedly connected to the sliding plate can realize the movement of the X-axis, the Y-axis or the Z-axis. Usually, the X-axis linear module 42, the Y-axis linear module 43, the Z-axis linear module 44 and the positioning linear module 646 all further include a slide rail 315 or a guide shaft and hole for guiding and supporting. Of course, the cooperation between the screw rod and the moving nut can also be replaced by a belt and a belt pulley, which will not be described here.

[0078] In another embodiment of the present application, as shown in Figure 1 , Figure 2 and Figure 4 , the conveying mechanism 20 of the automobile glass spherical surface detection device provided includes two conveying belt assemblies 21 which are installed in parallel and spaced apart on opposite sides of the rack 10. Specifically, the left and right sides of the automobile glass 80 are respectively placed on the conveying belts of the two conveying belt assemblies 21 for conveying, so that the contact area of the automobile glass 80 with the conveying belts is small, and the automobile glass 80 is not mostly in a suspended state, which can effectively avoid the problems of scratching or collision of the automobile glass 80, and at the same time, the conveying mode of the conveying belt assembly 21 has a simple structure and stable and reliable conveying.

[0079] In another embodiment of the present application, as shown in Figure 1 and Figure 3 , an automobile glass spherical surface detection method is provided, which adopts the automobile glass spherical surface detection device described above and specifically includes the following steps:

[0080] The automobile glass 80 is provided, and the surface of the automobile glass 80 has a plurality of detection curves 81;

[0081] The automobile glass 80 is placed on the conveying surface of the conveying mechanism 20 for conveying, and the positioning mechanism 30 performs positioning operation on the automobile glass 80 after the automobile glass 80 is conveyed to a preset position on the conveying surface. It should be noted that, as shown in the figure, in the spherical surface detection of the automobile glass 80, three detection curves 81 extending along the longitudinal direction of the surface of the automobile glass 80 are generally needed to measure specific points. Usually, three specific points 82 are needed for one detection curve 81, and then the distance value of each specific point 82 to the straight line 84 determined by the two edge points of the corresponding detection curve 81 is measured, and the distance value is compared with the standard distance value, so as to determine whether the detected automobile glass 80 meets the requirements. Figure 1

[0082] The moving mechanism 40 is started, and the moving mechanism 40 drives the distance measuring sensor 50 to move along each detection curve 81 in turn. In the process of moving the distance measuring sensor 50 along the detection curve 81, the distance measuring sensor 50 obtains the distance information between a plurality of points on the detection curve 81 and the detection end of the distance measuring sensor 50 and feeds back to the control device. At the same time, the moving mechanism 40 feeds back the position information of each point to the control device in real time. The control device fits a plurality of virtual curves 86 according to the distance information and the position information. Each virtual curve 86 corresponds to each detection curve 81 one by one.

[0083] The control device analyzes and calculates the spherical value of the automobile glass 80 according to the measured virtual curve 86. It should be noted that after the control device fits the continuous virtual curve 86 according to the distance information and the position information of a plurality of points, a straight line 84 tangent to the two ends of the virtual curve 86 is calculated and analyzed, a plurality of detection points 83 (for example, the distance between the detection point 83 and the intersection between the straight line 84 and the detection curve 81 is 100mm, 200mm, 300mm or 400mm) are evenly spaced on the straight line 84, then the perpendicular line 85 perpendicular to the straight line 84 is drawn through the detection point 83 and intersects with the virtual curve 86, and finally the length H of the perpendicular line 85 between the straight line 84 and the virtual curve 86 is calculated, so as to obtain the distance value from the detection point 83 to the automobile glass 80. The above steps are repeated to detect each detection point 83 on each virtual curve 86 in turn, and then the obtained distance value is compared with the corresponding standard distance value in turn. If the measured distance value is within the allowable error range of the standard distance value, it can be determined that the spherical surface of the automobile glass 80 meets the requirements. Conversely, the same is true.

[0084] ​The automobile glass spherical surface detection method of the embodiment of the present application, since the automobile glass spherical surface detection device is adopted, the coordinated action of the distance measuring sensor 50, the moving mechanism 40 and the control device is utilized, so that a plurality of virtual curves 86 which are adapted to the spherical surface of the automobile glass 80 are simulated on the automobile glass 80, then the control device is used to calculate and analyze the virtual curves 86 to obtain the spherical surface value. Compared with the method of only detecting a plurality of specific points 82 on the automobile glass 80, the detection result precision is high and the accuracy is better. In addition, the automobile glass spherical surface detection method can realize real-time, on-line and continuous precise measurement and automatic detection of the spherical surface of the automobile glass 80, so that the production rhythm of the automobile glass 80 can be quickly adapted, the production efficiency of the automobile glass 80 is not affected, and the defective products can be returned to the furnace in time, thereby reducing the labor intensity of the operators.

[0085] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
