Description

Technical Field

[0001] This invention relates to the field of electronic truck scale spraying technology, specifically to an adaptive spraying device and spraying method for electronic truck scales. Background Technology

[0002] Electronic truck scales, as core weighing and metering equipment in industrial and mining enterprises, logistics ports, building materials and chemical industries, are exposed to complex outdoor environments with high dust, high humidity, acid and alkali corrosion, and vehicle impact. Their supporting base and frame structures are highly susceptible to oxidation, rust, paint peeling, corrosion, and aging. This not only damages the equipment's appearance but also reduces the strength of the metal structure, causes component corrosion and jamming, affects weighing accuracy and equipment lifespan, and in severe cases, can lead to inaccurate measurement, equipment malfunctions, and downtime. Therefore, anti-corrosion coating maintenance of electronic truck scales is one of the core procedures in equipment operation and maintenance.

[0003] Currently, the industry commonly uses fixed-track semi-automatic spraying equipment for electronic truck scale painting. Electronic truck scale painting involves painting the support base, which is formed by welding together multiple crossbeams and longitudinal beams. Traditional fixed semi-automatic spraying equipment operates on a preset fixed track, requiring the support base to be painted to be placed in a standard position before spraying. However, in actual operation, the support base, composed of multiple crossbeams and longitudinal beams, is too heavy. After being loaded and placed by an overhead crane, it is inconvenient to make secondary adjustments to its position. Furthermore, if the support base is tilted, it causes spraying deviations in the preset fixed-track painting process, affecting the quality of the finished product. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adaptive spraying device and method for electronic truck scales. The main purpose is to solve the problem that in actual spraying operations, spraying deviations can easily occur due to the skewed placement of the electronic truck scale support base, leading to spraying operations that follow a preset fixed trajectory, thus affecting the quality of the finished product.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adaptive spraying device for electronic truck scales, comprising:

[0007] Hollowed-out spray painting workbench;

[0008] The two-axis adjustment system includes a horizontal moving linear module and a vertical adjusting linear module. The horizontal moving linear module is installed on both sides of the hollow spraying worktable, and the vertical adjusting linear module is installed between the horizontal moving linear modules through the horizontal moving bracket.

[0009] The adaptive position adjustment system includes a rotating bracket and two extension brackets. The rotating bracket is mounted on the side of the longitudinal adjustment linear module via a rotation drive assembly. The two extension brackets are fixedly mounted at both ends of the rotating bracket. One extension bracket has a left distance sensor 1 and a left distance sensor 2 installed at its end, and the other extension bracket has a right distance sensor 1 installed at its end.

[0010] The spraying system has a longitudinally moving spraying linear module mounted on the side of the rotating bracket. The spraying system is mounted on the side of the longitudinally moving spraying linear module slide table via the vertically moving linear module.

[0011] As a further embodiment of the present invention, the positions of the left distance sensor and the right distance sensor are corresponding, and the left distance sensor and the right distance sensor are parallel to the movement trajectory of the longitudinal moving spraying linear module of the spraying system.

[0012] The left distance sensor 1 and the left distance sensor 2 are perpendicular to the movement trajectory of the longitudinal moving spraying linear module of the spraying system.

[0013] As a further embodiment of the present invention, the distance between the two extension brackets is greater than the width of the electronic truck scale, the distance between the two extension brackets is much smaller than the width of the lateral moving bracket, and the ends of the two extension brackets are far away from the spraying system.

[0014] As a further embodiment of the present invention, the rotation drive assembly includes:

[0015] The mounting bracket is fixed to one side of the longitudinal adjustment linear module slide by bolts. The mounting bracket has a rotating shaft installed inside by bearings, and the rotation center of the mounting bracket is fixedly connected to the bottom end of the rotating shaft.

[0016] The drive gear and driven gear mesh with each other. The drive gear is rotatably mounted inside the mounting bracket. The driven gear is fixed to the top of the rotating shaft by bolts. A rocker arm is fixedly mounted on the top of the drive gear. A hydraulic cylinder is hinged to one side of the mounting bracket, and the end of the piston rod of the hydraulic cylinder is rotatably connected to the rocker arm.

[0017] The stabilizing component and stabilizing ring are fixedly mounted on the top of the rotating bracket, and the axis of the stabilizing ring coincides with the axis of the rotating shaft.

[0018] As a further embodiment of the present invention, the stabilizing component includes two dampers, which are respectively hinged to the bottom sides of the mounting bracket, and the other end of the dampers is rotatably connected to the stabilizing ring.

[0019] As a further embodiment of the present invention, the stabilizing component includes two gripping arms, which are respectively fixed to both sides of the mounting bracket by bolts. Both ends of the gripping arms are provided with gripping grooves that conform to the shape of the stabilizing ring. The inner wall of the gripping groove is detachably fitted with a friction element that contacts the outer side of the stabilizing ring. The friction element is a rubber pad.

[0020] As a further embodiment of the present invention, the spraying system includes:

[0021] The spraying bracket is installed on one side of the longitudinally moving spraying linear module slide, and the bottom end of the spraying bracket is fixed with a cross adjustment bracket by bolts.

[0022] The two sets of spray guns, one and two, are detachably mounted around the cross-shaped adjustment frame.

[0023] As a further embodiment of the present invention, the distance between the two sets of spray guns is less than the distance between the crossbeams of the electronic truck scale, and they are tilted toward the crossbeams of the electronic truck scale.

[0024] The distance between the two sets of spray guns is less than the distance between the longitudinal beams of the electronic vehicle scale, and they are tilted towards the longitudinal beams of the electronic vehicle scale.

[0025] The spraying method of the adaptive spraying equipment for electronic truck scales includes the following steps:

[0026] S1: The electronic truck scale support base is hoisted and placed on the hollow spraying work platform;

[0027] S2: Left distance sensor 1 and left distance sensor 2 calculate the deflection angle. And rotate and adjust the rotating bracket so that the rotating bracket is parallel to the electronic truck scale support base;

[0028] S3: Calculation of left distance sensor 1 and right distance sensor 1 And move the rotating bracket laterally so that the rotating bracket is centered with the electronic truck scale support base;

[0029] S4: Perform the spraying operation. The X-axis, Y-axis and Z-axis are moved by the horizontal moving linear module, the vertical moving spraying linear module and the vertical moving linear module, and the spraying operation is performed on the crossbeam and longitudinal beam of the electronic truck scale support base.

[0030] S5: When moving along the X-axis, real-time calculations are required using the left distance sensor 1 and the right distance sensor 1. The value is adjusted, and the position of the rotating bracket is adjusted so that the rotating bracket and the electronic truck scale support base are always parallel and centered.

[0031] Compared with the prior art, the present invention provides an adaptive spraying device and spraying method for electronic truck scales, which has the following beneficial effects:

[0032] 1. This invention, through the cooperation of left distance sensor one and left distance sensor two with a rotary drive component, can automatically calculate the tilt angle of the electronic truck scale support base and adjust the rotating bracket to be parallel to it, eliminating the need for manual secondary correction of the position of the heavy electronic truck scale base, adapting to the actual working conditions of overhead crane loading, and greatly improving loading efficiency.

[0033] 2. This invention uses a left distance sensor and a right distance sensor to measure the offset ΔC between the base and the rotating bracket, and completes the centering calibration of the rotating bracket to ensure that the spraying trajectory is completely matched with the base. This avoids the deviation problem of traditional fixed trajectory spraying from the root and improves the spraying quality of the finished product.

[0034] 3. The design of the stabilizing component of this invention, combined with the coaxial stabilizing ring, can effectively counteract the inertial impact and off-center stress during the rotation of the rotating support, thereby improving the stability of the rotation and braking process and significantly extending the service life of core transmission components such as the rotating shaft.

[0049] Please see Figures 1-10 As shown, an adaptive spraying device for electronic truck scales includes: a two-axis adjustment system, an adaptive position adjustment system, and a spraying system installed on a hollow spraying workbench 1, which is used to solve the problem that existing spraying equipment cannot adapt to spraying operations on the support base of electronic truck scales.

[0050] Currently, the electronic truck scale painting operation in the industry generally adopts fixed trajectory semi-automatic painting equipment. The electronic truck scale painting is the painting of the electronic truck scale support base after multiple cross beams and longitudinal beams are welded together.

[0051] Traditional fixed semi-automatic spraying equipment operates on a preset fixed trajectory. The electronic truck scale support base to be sprayed needs to be placed in a standard position before the spraying operation can be carried out. However, in actual operation, the electronic truck scale support base, which is welded together from multiple crossbeams and longitudinal beams, is too heavy. After the material is placed by the overhead crane, it is not convenient to make secondary position adjustments to the electronic truck scale support base. When the electronic truck scale support base is tilted, it will cause spraying deviations in the spraying operation that operates on the preset fixed trajectory, affecting the quality of the finished product.

[0052] The adaptive spraying method consists of the following steps:

[0053] Step 1: The electronic truck scale support base is hoisted and placed on the hollow spray painting workbench 1;

[0054] Step 2: Calculate the skew angle using left distance sensor 1 (601) and left distance sensor 2 (602). And rotate and adjust the rotating bracket 5 so that the rotating bracket 5 is parallel to the electronic truck scale support base;

[0055] Step 3: Calculate distance using left distance sensor 601 and right distance sensor 603. And move the rotating bracket 5 laterally so that the rotating bracket 5 is centered with the electronic truck scale support base;

[0056] Step 4: Perform the spraying operation. The X-axis, Y-axis and Z-axis are moved by the horizontal moving linear module 2, the vertical moving spraying linear module 7 and the vertical moving linear module 8, and the electronic truck scale support base crossbeam and longitudinal beam are sprayed.

[0057] Step 5: When moving along the X-axis, real-time calculations are required using the left distance sensor 601 and the right distance sensor 603. The value is adjusted, and the position of the rotating bracket 5 is adjusted so that the rotating bracket 5 and the electronic truck scale support base are always in a parallel and centered position.

[0058] Specifically:

[0059] The two-axis adjustment system includes a horizontal moving linear module 2 and a vertical adjusting linear module 4. The horizontal moving linear module 2 is installed on both sides of the hollow spraying workbench 1, and the vertical adjusting linear module 4 is installed between the horizontal moving linear modules 2 through the horizontal moving bracket 3.

[0060] The lateral linear module 2 consists of two sets of guide rails, a slide table, synchronous pulleys, a synchronous belt, a synchronous drive shaft, and a servo motor. The lateral moving bracket 3 is slidably mounted on the top of the two sets of guide rails via the slide table. The two sets of synchronous pulleys are respectively mounted on the two sets of guide rails. The two sets of synchronous pulleys (driving pulley and driven pulley) are respectively mounted at both ends of the guide rails and are wound with synchronous belts. The synchronous belts are connected and fixed to the lateral moving bracket 3. The two driving pulleys are fixedly connected to the synchronous drive shaft. The servo motor is connected to the synchronous drive shaft via a coupling. Therefore, the servo motor drives the synchronous drive shaft, thereby synchronously driving the two sets of synchronous pulleys to rotate, thus realizing the synchronous and stable drive of the lateral moving bracket 3.

[0061] The adaptive position adjustment system includes a rotating bracket 5 and two extension brackets 6. The rotating bracket 5 is mounted on the side of the longitudinal adjustment linear module 4 via a rotation drive assembly 9.

[0062] Two extension brackets 6 are fixedly installed at both ends of the rotating bracket 5. One extension bracket 6 has a left distance sensor 601 and a left distance sensor 602 installed at its end, and the other extension bracket 6 has a right distance sensor 603 installed at its end. The ends of the two extension brackets 6 are far away from the spraying system, which effectively reduces the impact of spraying on the left distance sensor 601, the left distance sensor 602 and the right distance sensor 603.

[0063] Specifically:

[0064] The left distance sensor 1 601 and the left distance sensor 2 602 are perpendicular to the longitudinal movement of the spraying linear module 7 of the spraying system. Then, the left distance sensor 1 601 and the left distance sensor 2 602 detect the distance to the side of the electronic truck scale support base to be sprayed placed on the hollow spraying workbench 1, which is used to calculate and determine the tilt angle of the electronic truck scale support base to be sprayed.

[0065] The tilt angle is adjusted by rotating the rotating drive assembly 9 so that the rotating bracket 5 is rotated to a position parallel to the electronic truck scale support base to be sprayed. The rotating drive assembly 9 includes a mounting bracket 901, a drive gear 904 and a driven gear 903 that mesh with each other.

[0066] Mounting bracket 901 is fixed to one side of the slide of longitudinal adjustment linear module 4 by bolts. Inside mounting bracket 901, rotating shaft 902 is rotatably mounted via bearings. The rotation center of rotating bracket 5 is fixedly connected to the bottom end of rotating shaft 902. Drive gear 904 is rotatably mounted inside mounting bracket 901. Driven gear 903 is fixed to the top end of rotating shaft 902 by bolts. Rocker arm 905 is fixedly mounted to the top end of drive gear 904. Hydraulic cylinder 906 is hinged to one side of mounting bracket 901. The end of piston rod of hydraulic cylinder 906 is rotatably connected to rocker arm 905.

[0067] It should be noted that the hydraulic cylinder 906 in this application is an actuator in a hydraulic system. It achieves the telescopic function by cooperating with the hydraulic system, and achieves precise control of the telescopic displacement of the hydraulic cylinder piston rod by cooperating with a magnetic switch, proximity switch or photoelectric switch. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0068] In this application, the linear modules used are all ball screw linear modules. The ball screw linear module achieves precise linear motion through the coordinated operation of various components: the slide table is the moving part, the ball screw and guide rail constitute the transmission core, the motor and coupling provide power, and the aluminum alloy profile and support base ensure structural stability. Furthermore, by cooperating with magnetic switches, proximity switches or photoelectric switches, the precise control of the slide table displacement can be achieved. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0069] When the rotating support 5 is adjusted in angle, the piston rod of the hydraulic cylinder 906 extends or retracts, which drives the drive gear 904 to rotate through the rocker arm 905. The rotation of the drive gear 904 drives the driven gear 903 and the rotating support 5 to rotate as a whole.

[0070] The positions of the left distance sensor 601 and the right distance sensor 603 are corresponding, and the left distance sensor 601 and the right distance sensor 603 are parallel to the movement trajectory of the longitudinal moving spraying linear module 7 of the spraying system. Therefore, by measuring the distance between the two sides of the electronic truck scale support base to be sprayed by the left distance sensor 601 and the right distance sensor 603, it is determined whether the electronic truck scale support base to be sprayed is centered.

[0071] If not centered, the linear module 4 is adjusted longitudinally to drive the rotary drive assembly 9 and the rotary bracket 5 to translate, so that the distance between the adjusted left distance sensor 601 and right distance sensor 603 and the two sides of the electronic truck scale support base to be sprayed is equal.

[0072] The adjustment mechanism is as follows:

[0073] The horizontal (X direction) distance between left distance sensor 1 601 and left distance sensor 2 602 is W;

[0074] L1: Distance from the left distance sensor 601 to the left edge of the electronic truck scale support base.

[0075] L2: Distance from the left distance sensor 2602 to the left edge of the electronic truck scale support base.

[0076] R1: Distance from the right distance sensor 603 to the right edge of the electronic truck scale support base.

[0077] B: Width of the electronic truck scale support base.

[0078] S: The distance between the left distance sensor 601 and the right distance sensor 603.

[0079]

[0080] : The angle of deviation of the electronic truck scale support base relative to the rotating bracket 5 (or baseline) (unit: radians).

[0081] A right triangle is constructed using the measurement difference between left distance sensor 1 (601) and left distance sensor 2 (602).

[0082] Because left distance sensor 601 and left distance sensor 602 are installed horizontally, a difference will occur between L1 and L2 when the electronic truck scale support base is tilted. This difference corresponds to the vertical drop of the edge of the electronic truck scale support base along the length W.

[0083] Therefore, the angle of deviation The calculation formula is:

[0084]

[0085] Direction judgment:

[0086] If L2 > L1, it indicates that the support base of the electronic truck scale tilts counterclockwise, at this time, is positive, and the rotating bracket 5 shall rotate counterclockwise .

[0087] If L2 < L1, it indicates that the support base of the electronic truck scale tilts clockwise, at this time, is negative, and the rotating bracket 5 shall rotate clockwise ∣ ∣.

[0088] After the rotating bracket 5 rotates to be parallel with the support base of the electronic truck scale, it is necessary to calculate the offset of the center line of the rotating bracket 5 relative to the center line of the support base of the electronic truck scale and make adjustment.

[0089]

[0090] Therefore, the offset is the distance that the rotating bracket 5 needs to move laterally, and also the moving distance of the longitudinally adjusting linear module 4;

[0091] If > 0, it indicates that L1 > R1, the rotating bracket 5 deviates to the right, and the longitudinally adjusting linear module 4 needs to drive the rotating bracket 5 to move left .

[0092] If < 0, it indicates that L1 < R1, the rotating bracket 5 deviates to the left, and the longitudinally adjusting linear module 4 needs to drive the rotating bracket 5 to move right ∣ ∣.

[0093] It should be noted that the distance between the two extension brackets 6 is greater than the width of the electronic truck scale, and the distance between the two extension brackets 6 is far less than the width of the laterally moving bracket 3, which provides avoidance space for the rotation position adjustment or horizontal position adjustment of the rotating bracket 5;

[0094] The first left distance sensor 601, the second left distance sensor 602 and the first right distance sensor 603 are all laser ranging displacement sensors, and the model of the laser ranging displacement sensor can be PDL-030-485.

[0095] Since when the rotating bracket 5 rotates, it needs to rotate together with the spraying system, the rotating bracket 5 and the mounting bracket 901 are only connected by the rotating shaft 902, and the gravity at the left and right ends of the rotating bracket 5 is not horizontal, the inertia generated during rotation greatly shortens the service life of the rotating shaft 902, and also results in poor stability of the rotating bracket 5 during and after rotation;

[0096] Therefore, a stabilizing component 908 and a stabilizing ring 907 are provided between the mounting bracket 901 and the rotating bracket 5 to improve the rotational stability of the rotating bracket 5. The stabilizing ring 907 is fixedly installed on the top of the rotating bracket 5, and the axis of the stabilizing ring 907 coincides with the axis of the rotating shaft 902.

[0097] Specifically, the stabilizing component 908 consists of two dampers 90801, which are hinged to the bottom sides of the mounting bracket 901 respectively. The other end of the damper 90801 is rotatably connected to the stabilizing ring 907. When the rotating bracket 5 rotates, it drives the stabilizing ring 907 to rotate synchronously. At this time, the distance between the two mounting positions of the damper 90801 changes, and the damper 90801 extends, making the stabilizing ring 907 more stable and smooth during rotation and when it stops.

[0098] It should be noted that the damper 90801 is a device that dissipates kinetic energy by providing motion resistance, rather than braking. Electromagnetic dampers, magnetorheological dampers, and friction dampers can be selected.

[0099] Furthermore, the stabilizing component 908 can also be two gripping arms 90802. The two gripping arms 90802 are respectively fixed to both sides of the mounting bracket 901 by bolts, and both ends of the gripping arms 90802 are provided with gripping grooves that conform to the shape of the stabilizing ring 907. The inner wall of the gripping groove can be detachably installed with friction parts 90803 that contact the outer side of the stabilizing ring 907. The friction parts 90803 are rubber pads, which can also achieve the same effect of increasing friction, making the stabilizing ring 907 more stable and smooth during rotation and when braking.

[0100] After the position of the rotating bracket 5 is adjusted, the spraying operation is required; the side of the rotating bracket 5 is equipped with a longitudinally moving spraying linear module 7, and the spraying system is installed on the side of the slide table of the longitudinally moving spraying linear module 7 via a vertically moving linear module 8.

[0101] The spraying system includes a spraying bracket 10 and two opposing sets of spray guns 1002 and 1003.

[0102] Specifically, the spraying bracket 10 is installed on one side of the slide table of the longitudinally moving spraying linear module 7, and the bottom end of the spraying bracket 10 is fixed with a cross adjustment frame 1001 by bolts; the two sets of spray guns 1002 and 1003 are detachably installed around the cross adjustment frame 1001.

[0103] Then, adjust the positions of the two sets of spray guns 1002 and 1003 according to the spacing between the crossbeams and longitudinal beams of the electronic truck scale.

[0104] The adjusted position must ensure that:

[0105] First: The distance between the two sets of spray guns 1002 is less than the distance between the crossbeams of the electronic truck scale support base, and they are tilted towards the crossbeams of the electronic truck scale support base.

[0106] Second: The distance between the two sets of spray guns 21003 is less than the distance between the longitudinal beams of the electronic truck scale support base, and they are tilted towards the longitudinal beams of the electronic truck scale support base.

[0107] Therefore, the spraying system is operated under the premise that the rotating bracket 5 and the electronic truck scale support base are horizontal and centered;

[0108] like Figure 7 As shown, movement along the X-axis is accomplished by the horizontal movement linear module 2; movement along the Y-axis is accomplished by the vertical movement spraying linear module 7; and movement along the Z-axis (spraying height) is accomplished by the vertical movement linear module 8.

[0109] Longitudinal beam spraying: First, the spraying system moves along the X-axis to the first spraying position (longitudinal beam), and then moves along the Y-axis to spray the adjacent surfaces and top surfaces of two adjacent longitudinal beams (two sets of spray guns 1003 work together for spraying); then the spraying system moves along the X-axis to the second spraying position (longitudinal beam), and so on, to complete the spraying of all longitudinal beams; during this process, when the spraying system moves along the X-axis to each spraying position, the position of the rotating bracket 5 needs to be adjusted to achieve centering;

[0110] Beam spraying: First, the spraying system moves along the Y-axis to the first spraying position (beam), and then moves along the X-axis to spray the adjacent surfaces and top surfaces of the two adjacent beams (two sets of spray guns - 1002 work together for spraying); then the spraying system moves along the Y-axis to the second spraying position (beam), and so on, to complete the spraying of all beams; during this process, the position of the rotating bracket 5 is adjusted at any time as the spraying system moves along the X-axis, always keeping the position centered.

[0111] It should be noted that: due to the skewness of the electronic truck scale support base, when the rotating bracket 5 moves along the X-axis, the values ​​need to be calculated in real time, and the position of the rotating bracket 5 needs to be adjusted by the longitudinal adjustment linear module 4 to ensure that the rotating bracket 5 and the electronic truck scale support base are always in a parallel and centered position.

[0112] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
