Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a batch welding device based on an electronic truck scale sensor. Background Technology

[0002] Electronic truck scale sensors are core components of weighing instruments and are widely used in industrial weighing, logistics measurement, and commercial settlement. These scenarios have stringent requirements for the structural strength and welding accuracy of the sensors. In the sensor welding process, circumferential welds are required for sensors of different diameters.

[0003] Existing electronic truck scale sensor welding equipment has limitations. Different diameter electronic truck scale sensors have different circumferences, requiring varying rotational speeds during welding. When the sensor diameter is small, a slow rotation speed can lead to over-welding, affecting weld formation. Conversely, a large diameter sensor requires a fast rotation speed, resulting in insufficient welding and similarly affecting weld formation. Furthermore, existing welding equipment is not conducive to adjusting the rotational speed according to different sensor diameters, leading to decreased welding quality. Additionally, it is difficult to adjust the damping effect based on the diameter of the sensor during welding, hindering the reduction of external vibrations from impacting weld formation and ultimately affecting welding quality.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a batch welding device based on electronic truck scale sensors, comprising a base, a cover fixed to the upper edge of the base, a multi-axis adjustment mechanism mounted on the rear side of the upper end of the base, a welding mechanism slidably connected to the upper left side of the multi-axis adjustment mechanism via a slide rod, a welding table rotatably mounted in a groove at the upper end of the base, a rotating mechanism connected to a shaft below the welding table, the rotating mechanism being installed inside the base, and multiple mounting holes equally spaced around the upper end of the welding table, wherein a welding mechanism is rotatably mounted via bearings. A rotating table has clamps slidably mounted in symmetrical grooves at its upper end. The outer ends of the two clamps are slidably mounted on symmetrical frames on the surface of the rotating table via springs. A connecting shaft is connected to the center of the lower end of the rotating table. A friction wheel is fixed to the outer side of the lower end of the connecting shaft. A second friction wheel is rubbed against the outer side of the first friction wheel. A slider is connected to the lower end of the second friction wheel via a motor. A groove seat is slidably connected to the lower end of the slider. An adjustment assembly is provided between the welding table and the clamps. An oil assembly is provided between the clamps, the adjustment assembly, and the slider.

[0007] Optionally, guide grooves are symmetrically provided on the side wall of the cavity at the lower end of the mounting hole, and the protrusions on both sides of the slider are slidably connected to the guide grooves, and the guide grooves are opened at an angle.

[0008] Optionally, the second friction wheel is designed as a conical structure, the inclined surface of the first friction wheel abuts against the inclined surface of the second friction wheel, the inclined surfaces of the second friction wheel and the first friction wheel are in opposite positions, and the inclination of the surface of the second friction wheel corresponds to the inclination of the guide groove.

[0009] Optionally, the oil assembly includes two sets of oil tanks, both sets of oil tanks being symmetrically fitted and installed inside the slide groove on the surface of the rotary table. A plug body is slidably installed in the inner cavity of each oil tank, and the inner ends of both sets of plug bodies are connected to two clamping plates. One set of oil tanks is connected to an oil tank second via an output hose. The oil tank second is installed at the bottom of the cavity at the lower end of the mounting hole. A plug body second is slidably installed in the inner cavity of the oil tank second via a spring seal. The upper end of the plug body second is connected to the bottom of the slide groove seat. The other set of oil tanks is connected to an adjustment component via an output hose.

[0010] Optionally, the adjusting component includes an oil chamber located at the upper end of a connecting shaft. The connecting shaft is connected through a central groove on a rotary table. A rubber plug is slidably and sealingly connected within the central groove of the rotary table. A connecting pipe is connected to the bottom of the oil chamber. The connecting pipe is vertically rotatably mounted within the connecting shaft via a bearing. The lower end of the connecting pipe is connected to another set of oil tanks via an output hose.

[0011] Optionally, the upper end of the rubber plug protrudes from the surface of the rotary table, the rubber plug is located between symmetrical clamping plates, the inner sides of the two sets of clamping plates are designed with a sloping structure, the two clamping plates are used to clamp the electronic truck scale sensor, the rubber plug is designed with a corrugated shape, and the rubber plug is used for shock absorption during the welding of the electronic truck scale sensor.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the coordination between the clamping plate and the hydraulic assembly, enables the welding mechanism to weld electronic truck scale sensors of different diameters. The thrust exerted on the clamping plate during the clamping process of the electronic truck scale sensor drives the hydraulic assembly, pushing the sliding seat and friction wheel two downwards. The inclined design of the guide groove adjusts the contact position between friction wheel two and friction wheel one, allowing friction wheel two to rotate at a smaller diameter position, creating a speed difference between them. This, in turn, causes the rotational speed of the rotary table to adaptively decrease as the diameter of the electronic truck scale sensor increases, achieving uniform welding of welds with different circumferences and improving the welding quality of welds from electronic truck scale sensors of different sizes.

[0014] This invention, through the coordination between the adjustment component and the hydraulic component, enables the clamping and welding of electronic truck scale sensors of different diameters. The outward movement of the clamping plate drives another hydraulic component to deliver hydraulic fluid to the bottom of the rubber stopper, allowing the height of the rubber stopper to be adjusted accordingly to the diameter of the electronic truck scale sensor. This allows for buffering and shock absorption during the welding process of electronic truck scale sensors of different diameters, with the shock absorption effect increasing as the diameter of the electronic truck scale sensor grows. This effectively reduces the impact of external vibrations on weld formation and further improves the overall welding quality of the electronic truck scale sensor. Attached Figure Description

[0017] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0018] Example 1 Please see Figures 1 to 8This invention provides a technical solution: a batch welding device based on electronic truck scale sensors, including a base 1, a cover 2 fixed to the upper edge of the base 1, a multi-axis adjustment mechanism 3 installed on the rear side of the upper end of the base 1, a welding mechanism 4 slidably connected to the upper left side of the multi-axis adjustment mechanism 3 via a slide rod, a welding table 5 rotatably installed in a groove at the upper end of the base 1, a rotating mechanism 6 connected to a shaft below the welding table 5, the rotating mechanism 6 being installed inside the base 1, multiple mounting holes 51 are equally spaced around the upper end of the welding table 5, guide grooves 52 are symmetrically formed on the side wall of the cavity at the lower end of the mounting holes 51, the two protrusions on both sides of the slider 13 are slidably connected to the guide grooves 52, the guide grooves 52 are inclined, a rotating table 7 is rotatably installed in the mounting holes 51 via bearings, clamping plates 8 are slidably installed in symmetrical sliding grooves at the upper end of the rotating table 7, the outer ends of the two clamping plates 8 are slidably installed on the symmetrical frame on the surface of the rotating table 7 via springs, and the welding table 5 and the clamping plates 8 are connected by a sliding mechanism 6. An adjustment assembly is provided, including an oil chamber 152. The oil chamber 152 is located at the upper end of the connecting shaft 9, which is connected to the central groove of the rotary table 7. A rubber plug 151 is slidably connected inside the central groove of the rotary table 7. A connecting pipe 153 is connected to the bottom of the inner cavity of the oil chamber 152. The connecting pipe 153 is vertically rotatably mounted inside the inner cavity of the connecting shaft 9 via a bearing. The lower end of the connecting pipe 153 is connected to another set of oil tanks 161 via an output hose. The upper end of the rubber plug 151 protrudes from the surface of the rotary table 7 and is located between symmetrical clamping plates 8. The inner sides of the two sets of clamping plates 8 are designed with a sloping structure. The two clamping plates 8 are used to clamp the electronic truck scale sensor. The rubber plug 151 is designed with a corrugated shape and is used to reduce vibration during the welding of the electronic truck scale sensor. Multiple openings are circumferentially opened at equal angles on the outer wall of the oil chamber 152 for oil delivery. When the clamping plate 8 moves outward, the oil in another set of oil tanks 161 is transported to the oil chamber 152 through the hose and connecting pipe 153. The oil then enters the bottom of the rubber plug 151 through the opening on the oil chamber 152, pushing the rubber plug 151 to complete the height adjustment. The rubber plug 151, through its own rubber material properties and corrugated structure, can absorb the vibration generated by the outside, thereby reducing the adverse effect of vibration on the weld formation during the welding process. At the same time, the larger the diameter of the electronic truck scale sensor, the longer its welding circumference and the longer the welding operation time. The height of the rubber plug 151 will be adjusted synchronously with the increase of the sensor diameter, and the shock absorption and protection effect will be further improved, thereby improving the welding quality of the electronic truck scale sensor.

[0019] Example 2 Based on Example 1, please refer to Figures 1 to 8A connecting shaft 9 is connected to the center of the lower end of the rotary table 7. A friction wheel 10 is fixed to the outer side of the lower end of the connecting shaft 9. A friction wheel 11 is connected to the outer side of the friction wheel 10. The friction wheel 11 is designed with a conical structure. The inclined surface of the friction wheel 10 abuts against the inclined surface of the friction wheel 11. The inclined surfaces of the friction wheel 11 and the friction wheel 10 are in opposite positions. The inclination of the surface of the friction wheel 11 corresponds to the inclination of the guide groove 52. The lower end of the friction wheel 11 is connected to a slider 13 via a motor 12. The lower end of the slider 13 is slidably connected to a slide seat 14. Oil is provided between the clamping plate 8, the adjusting component and the slider 13. The component, the oil component, includes two sets of oil tanks 161. Both sets of oil tanks 161 are symmetrically fitted inside the slide groove on the surface of the rotary table 7. The inner cavity of the oil tank 161 is sealed and slidably installed with a plug 162. The inner ends of both sets of plugs 162 are connected to two clamping plates 8. One set of oil tanks 161 is connected to an oil tank 163 through an output hose. The oil tank 163 is installed at the bottom of the cavity at the lower end of the mounting hole 51. The inner cavity of the oil tank 163 is sealed and slidably installed with a plug 164 through a spring. The upper end of the plug 164 is connected to the bottom of the slide groove seat 14. The other set of oil tanks 161 is connected to an adjustment component through an output hose.

[0020] Different diameter electronic truck scale sensors push the clamping plate 8 to move outward by different distances. When the sensor diameter is larger, the outward movement of the clamping plate 8 will push the corresponding plug 162 in the oil tank 161 to move, so that the oil in the oil tank 161 enters the oil tank 2 163 through the delivery hose, pushing the plug 2 164 to move and pulling the slide seat 14 downward, causing the friction wheel 2 11 to slide with the slider 13. At the same time, with the inclined design of the guide groove 52, the friction wheel 2 11 moves obliquely downward along the inclined surface of the friction wheel 10, and rubs against the friction wheel 10 at a position with a smaller diameter. The two form a speed difference. The small diameter friction wheel 2 11 drives the large diameter friction wheel 10 to rotate, slowing down the speed of the rotary table 7, thereby realizing the uniform speed welding of welds with different circumferences by the welding mechanism 4.

[0021] Working principle: When using this batch welding device based on electronic truck scale sensors, firstly, the welding table 5 is provided with multiple mounting holes 51, and a rotating table 7 is installed inside each set of mounting holes 51. The electronic truck scale sensors are placed into the rotating table 7 in the mounting holes 51 in sequence. The rotating mechanism 6 at the bottom of the welding table 5 drives the welding table 5 to rotate on the machine base 1, and aligns it with the welding mechanism 4 above in sequence, which facilitates the subsequent batch welding of the electronic truck scale sensors. According to different diameter sizes, the electronic truck scale sensors are pushed from top to bottom between the symmetrically arranged clamping plates 8. As the clamping plates 8 enter, the clamping plates 8 on both sides are pushed outward, so that the clamping plates 8 complete the clamping of the electronic truck scale sensors. The motor 12 drives the friction wheel 2 11 to rotate. The friction wheel 2 11 drives the friction wheel 10 to rotate one revolution by frictional contact with the friction wheel 10. The friction wheel 10 drives the rotating table 7 to rotate through the connecting shaft 9. The welding mechanism 4 cooperates with the rotation of the rotating table 7 to weld the electronic truck scale sensors. Based on the above, since the thrust exerted on the clamping plate 8 by electronic truck scale sensors of different diameters varies, the outward movement distance of the clamping plate 8 is affected by the size of the electronic truck scale sensor. When the diameter of the electronic truck scale sensor is large, when the clamping plate 8 moves outward, it will push the plug 162 in one of the sets of oil tanks 161 to move its position. The oil in oil tank 161 enters oil tank 263 through the delivery hose. After the oil enters oil tank 263 from oil tank 161, it pushes the plug 164 in oil tank 263 to move its position, pulling the slide seat 14 downward. During the downward movement of the slide seat 14, the friction wheel 11 moves downward together with it, cooperating with... The slider 13, which is set to slide on the surface, adjusts the position of the second friction wheel 11 by sliding the slider 13. At the same time, the movement of the second friction wheel 11 is coordinated with the inclined design of the guide groove 52 to slide, so that the second friction wheel 11 moves along the inclined surface of the first friction wheel 10 and moves against the downward friction of the first friction wheel 10. This allows the second friction wheel 11 to drive the first friction wheel 10 to rotate through the position of the smaller diameter. During this process, there is a speed difference between the first friction wheel 10 and the second friction wheel 11. The smaller diameter of the second friction wheel 11 drives the larger diameter of the first friction wheel 10 to rotate, which slows down the rotation speed of the rotary table 7, so that the welding mechanism 4 can perform uniform welding on welds of different circumferences. Based on the above, the clamping plate 8 moves outward, and the oil in another set of oil tanks 161 enters the oil chamber 152 through the hose and connecting pipe 153. The oil enters the bottom of the rubber plug 151 through the opening on the oil chamber 152, so that the height of the rubber plug 151 is adjusted. The rubber material and corrugated structure of the rubber plug 151 itself absorb the external vibration, thereby reducing the impact of vibration on the weld during welding. At the same time, when the diameter of the electronic truck scale sensor is larger and the welding circumference and time are longer, the corresponding adjustment of the height of the rubber plug 151 further improves the absorption effect of external vibration waves and improves the welding quality of the electronic truck scale sensor.
