Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, and more specifically, to an automatic weighing scale platform polishing and forming preparation device without stress activators. Background Technology

[0002] Anxiety-free automatic weighing scales, with their advantages of balanced force, accurate weighing, and strong adaptability, are widely used in many fields such as industrial material measurement, warehouse weighing, and poultry farming. The flatness, smoothness, and edge regularity of the weighing platform directly determine the weighing accuracy and safety of use. Currently, most factories in the industry produce the platforms of anxiety-free automatic weighing scales using an integral stamping process. This process has the advantages of fast forming speed and low mass production cost, making it suitable for large-scale production needs. However, the inherent defects of stamping are quite prominent. After the sheet metal is subjected to stamping, extrusion, cutting, and shaping, burrs, flash, and sharp protrusions are easily generated at the four corners of the platform. At the same time, there may be slight unevenness in some areas of the platform. If fine grinding is not performed, it will not only affect the flatness of the platform's appearance, but the sharp edges are also more likely to cause scratches, posing a safety hazard. Therefore, the platform after stamping must undergo a special grinding process for fine processing.

[0003] Currently, for the grinding of protrusions and burrs on the edges of weighing platform surfaces, most small and medium-sized manufacturers in China rely on manual hand-held grinding equipment. Only a few large enterprises are equipped with simple semi-automatic grinding equipment. The overall processing mode is relatively outdated. Manual grinding requires a high level of operator skill, and it is difficult to maintain consistent grinding force and angle, easily leading to uneven grinding, over-grinding, or under-grinding. This results in poor product consistency. Furthermore, manual grinding is labor-intensive and has extremely low production efficiency, making it unsuitable for large-scale assembly line production and significantly increasing labor costs and production cycle costs.

[0004] In view of this, we propose an automatic weighing scale platform grinding and molding preparation device without stress activators. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This device is equipped with a vertically lifting negative pressure adsorption component. During the processing stage, the suction tube uses air holes to regulate negative pressure and fix the workpiece on the weighing platform after stamping. After the workpiece is pressed, it can press down the positioning plate to cause the compression spring to deform. Based on this structure, it can buffer the hard extrusion force generated when the workpiece is pressed, thereby reducing the probability of indentation on the surface of the weighing platform. The wear-resistant texture set on the surface of the positioning plate can increase the friction coefficient between the contact surfaces. Furthermore, when the servo motor drives the workpiece to rotate at a constant speed to carry out edge grinding, the workpiece is less likely to slip laterally. After one round of grinding operation is completed, the first electric push rod can drive the adsorbed and fixed workpiece on the weighing platform to make a fine adjustment of the height. By comparing the lifting stroke, the thickness specification of the workpiece after grinding can be checked. Thus, the workpiece self-inspection can be completed inside the equipment, without the need to add a separate external inspection device, thereby improving the production efficiency and consistency of the weighing platform.

[0020] 2. The waste collection structure consists of a receiving box, connecting pipe, waste bin, and fan. After the grinding wheel cuts the raised part of the weighing platform, metal chips are generated. The chips fall into the receiving box. Thanks to the guiding effect of the inclined bottom of the receiving box, the chips gather in one place. Then, the fan creates a negative pressure airflow to carry the dust along the pipeline into the waste bin. The sealing plate can block the gaps on the side of the box, thereby preventing the grinding dust from drifting out into the processing environment. Attached Figure Description

The lifting rod 318 can cooperate to complete vertical lifting and fine adjustment operations. A positioning plate 319 is fixedly installed on the top of the lifting rod 318. On the one hand, the positioning plate 319 can directly contact the bottom of the workpiece, playing a role in auxiliary positioning and support. On the other hand, the top of the positioning plate 319 is provided with wear-resistant texture, which can increase the friction between the positioning plate and the workpiece and reduce the workpiece sliding and deviation. At the same time, a compression spring 320 is sleeved on the outer periphery of the lifting rod 318. The compression spring 320 can provide elastic buffer force to adapt to the small fit adjustment of the workpiece, thereby reducing the processing deviation caused by rigid contact. In addition, the top of the compression spring 320 abuts against the bottom surface of the positioning plate 319, and the bottom surface of the compression spring 320 abuts against the top surface of the first limiting block 317, thereby ensuring the stable operation of the elastic structure.

The push plate 10 can follow the third electric push rod 9 to reciprocate and slide along the calibration hole 302, thereby accurately pushing the workpiece to complete the alignment and calibration operation.

[0043] A receiving box 306 is fixedly installed at the bottom of the rectangular hole 201 near the lower part of the alignment frame 301. During daily operation, the receiving box 306 can receive waste debris generated during grinding and processing, preventing waste from scattering and accumulating.

In terms of precision control, the second support block 701 is symmetrically provided with a limiting rod 709 that moves through the bottom end of the vertical plate 702. The limiting rod 709 can guide and limit the adjustment movement of the vertical plate 702 to ensure the accuracy of the grinding position adjustment.

[0048] A control cabinet 4 is installed on one side of the bottom of the welding station 1. From an overall perspective, the control cabinet 4 is responsible for the placement of all electrical components of the machine and can uniformly control the start-up, stop and action sequence of each actuator. On this basis, the control cabinet 4 is electrically connected to the servo motor 308, the first electric push rod 312, the fan 502, the drive motor 703, the second electric push rod 708 and the third electric push rod 9. Then, it controls the extension, rotation or start-up and stop of each power component by means of electrical signal transmission. When the equipment is stationary, the support legs 101 arranged at the four corners can stably support the entire device and ensure the overall stability of the equipment during operation. When the equipment is transported, a pulley is provided on one side of the support leg 101.

[0049] It should be noted that the control components inside the control cabinet 4, as well as the servo motor 308, the first electric push rod 312, the fan 502, the drive motor 703, the second electric push rod 708, and the third electric push rod 9 connected to the control cabinet 4 by wires, all adopt commercially available mature and common equipment. The power supply logic, signal acquisition logic, and data transmission logic between the entire set of electrical components are all existing mature control technologies. This application does not make any improvements to the circuit control program and electrical connection method. Therefore, the relevant control principles and circuit layout logic will not be described in detail here.

[0050] Working principle:

[0051] The stamped workpiece with burrs and protrusions is placed on the feeding table 601. With the guidance of the first chute 602, the workpiece can be smoothly transported. Then, the workpiece slides along the inclined groove 305 inside the guide frame 304 to match the workpiece feeding angle, so that the workpiece is smoothly fed into the internal processing area of ​​the alignment frame 301, completing the workpiece loading and positioning process. After loading, the control cabinet 4 sends a control signal to start the first electric push rod 312. The first electric push rod 312 performs a vertical extension and retraction action, which can adjust the height according to the thickness of the workpiece on the weighing platform, thereby driving the top suction tube 313 to approach the bottom surface of the workpiece. At the same time, the suction tube 313 adjusts the internal air pressure through the bottom air hole to form a negative pressure adsorption effect on the workpiece. The rubber sleeve 315 and the rubber pad 316 are directly attached to the bottom surface of the workpiece, which can play a buffering and protective role and avoid wear on the surface of the workpiece.

[0052] During the workpiece adsorption and bonding process, the workpiece's own weight and bonding pressure will press down on the positioning plate 319, causing the positioning plate 319 to drive the lifting rod 318 to slide vertically along the first limit block 317, simultaneously compressing the outer compression spring 320. Utilizing the elastic buffering performance of the compression spring 320, it adapts to small bonding deviations of the workpiece, effectively improving the bonding stability of the workpiece adsorption and fixation. The wear-resistant texture on the surface of the positioning plate 319 can increase the friction of the contact surface, thereby reducing the slippage and displacement of the workpiece during processing.

[0053] After the workpiece is fixed, the control cabinet 4 starts the servo motor 308. The servo motor 308 drives the main gear 309 to rotate, and through the gear meshing transmission relationship, drives the driven gear 3090 to rotate synchronously. This drives the drive column 310 to rotate smoothly under the support of the triangular protrusion, thereby driving the first support block 311 and the workpiece on the weighing platform fixed at the top to rotate at a uniform speed. In addition, during the lifting and lowering of the suction tube 313, the guide rod 314 and the first support block 311 are engaged to limit and guide the movement trajectory of the suction tube 313, ensuring the stability of the workpiece rotation operation. While the workpiece is rotating, the control cabinet 4 starts... The second electric push rod 708 is telescopically adjustable, which can drive the vertical plate 702 to slide horizontally along the limiting rod 709, thereby finely adjusting the horizontal processing position of the grinding wheel 706 to adapt to the grinding needs of different scale platforms. The drive motor 703 is started simultaneously, and the drive motor 703 drives the grinding wheel 706 to rotate at high speed through the drive shaft 704. The second limiting block 705 can limit the radial sway of the drive shaft 704 to ensure the stability of the grinding operation. The rotating grinding wheel 706 continuously contacts the edges and corners of the rotating scale platform, gradually trimming the burrs and sharp protrusions on the surface of the workpiece, and completing the fine grinding operation of the platform.

[0054] While the grinding operation is underway, the metal shavings and dust generated during grinding naturally fall into the receiving box 306. The inclined structure at the bottom of the receiving box 306 can guide the shavings to slide and collect autonomously, facilitating the centralized collection of waste materials. At the same time, the control cabinet 4 starts the fan 502, which creates a negative pressure environment inside the waste box 5. The fan 502 draws out the dust and fine waste materials inside the receiving box 306 through the connecting pipe 3061, realizing the directional conveying and collection of waste materials. The sealing plate 3060 can seal the gaps and reduce dust leakage. After the operation is completed, the staff can open the door 501 to regularly clean the waste materials accumulated inside the waste box 5. After a single grinding process is completed, each electric push rod and motor resets in sequence, and the equipment returns to the initial processing state. Relying on the vertical fine adjustment function of the first electric push rod 312, the workpiece can be moved up and down slightly. This is used to compare and detect the thickness of the workpiece after grinding, completing the self-inspection and screening of the workpiece grinding quality, and selecting the qualified workpieces.

[0055] After the workpiece passes inspection, the control cabinet 4 activates the third electric push rod 9. The third electric push rod 9 extends and drives the push plate 10 to slide along the calibration hole 302 inside the alignment frame 301, so as to accurately push the qualified workpiece. The workpiece is then sent out of the processing area through the discharge hole 303. Finally, the workpiece is discharged along the second slide groove 603 at the bottom of the top plate 2. In summary, after the equipment completes a single workpiece grinding process, the above process can be repeated continuously to achieve continuous batch grinding of workpieces on the weighing platform.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
