Description

Technical Field

[0001] The present invention relates to the technical field of intelligent robots, and particularly to a positioning and loading guiding mechanism and method for a flexible production line. Background Art

[0002] A flexible manufacturing production line is a production mode that meets the requirements of multi-variety and small-batch production. The necessary configurations for this production mode are independent quick-change fixtures (or fixtures installed on the quick-change pallets of machine tools), transportation equipment for transferring fixtures, loading station equipment, pre-adjustment table equipment, cleaning equipment. The quick-change fixtures have certain range requirements for the external dimensions of workpieces. Preventing misloading beyond the working range of the machine tool or the dimension range of auxiliary machine transfer will cause accidents such as machine collisions.

[0003] In order to prevent operators from loading workpieces with dimensions exceeding the safe size range onto the flexible production line tooling fixtures, a device for guiding and prompting operators is specially designed. This device does not intervene in the automatic control logic of the production line to avoid too many control logic errors, resulting in the instability of the production line operation. This device uses a projection light source. According to the range dimensions of different tooling fixtures, different projection profiling dimensions are designed and installed directly above the manual loading station. The light can be designed in warning colors (yellow or red). After adjusting the focal length, it is a safety device that prompts the loading personnel not to load beyond the range. Summary of the Invention

[0004] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a positioning and loading guiding mechanism and method for a flexible production line, which solves the situation that during the clamping of workpieces, misloading beyond the working range of the machine tool or the dimension range of auxiliary machine transfer may cause machine collision accidents.

[0005] (II) Technical Solutions To achieve the above object, the present invention is realized through the following technical solutions: A positioning and loading guiding mechanism for a flexible production line includes a base platform and a mounting frame. It is characterized in that: a workpiece is arranged on the base platform; brackets are bolt-mounted at both ends below the middle of the mounting frame; cross beams are bolt-mounted at the inner ends of the brackets; a movable frame is arranged outside the cross beams; a plurality of screw holes are opened at one end of the movable frame close to the bracket, and a plurality of positioning bolts I are threadedly connected to the outer end of the movable frame through the screw holes; an adjusting plate is slidably connected to the bottom of the movable frame; A positioning plate is provided at the connection between the adjusting plate and the movable frame. A third positioning bolt is threadedly connected between the positioning plate and the adjusting plate. The inner end of the adjusting plate is fixedly connected with a lamp body mounting seat. A lamp body is correspondingly installed inside the lamp body mounting seat. Two groups of second positioning bolts are threadedly connected to both outer ends of the lamp body mounting seat. The inner ends of the second positioning bolts are in contact with the lamp body. A socket is fixedly connected to the cross beam, and a limiting member is installed inside the two movable frames.

[0006] A positioning and loading guiding method for a flexible production line includes the following steps: S1. Select a metal template and process holes for workpieces of different shapes on the template so that the holes on the template can be consistent with the shapes of a variety of workpieces. S2. When processing workpieces of the same batch, select a template with the same shape as the workpiece to be processed, install the template at the light source opening position of the lamp body, and lock and fix it to ensure the stability of the template during use. And when replacing workpieces of different shapes subsequently, only need to remove and replace the internal template together. S3. Install the adjusting plate on the movable frame, move the adjusting plate to a suitable position, and lock it with the third positioning bolt. Then install the lamp body inside the two lamp body mounting seats and lock it at both ends with the second positioning bolts. S4. Conduct a preliminary debugging of the lamp body. The lamp body is designed in a cylindrical shape, and an LED strong light source is installed inside the cylindrical lamp body to provide light with sufficient brightness. The mold is located in front of the light source. Since the middle part of the mold is the specified hollow shape of the workpiece to be processed, a specific pattern is formed when the light passes through. The light emits from the light source, propagates in a straight line, and passes through the mold to form a light and shadow consistent with the shape of the mold. S5. Since the sizes of the workpieces are different, adjustment still needs to be made after the lamp body is installed. When dealing with workpieces of different sizes but the same shape, only need to loosen the second positioning bolts to enable the lamp body to be adjusted up and down inside the lamp body mounting frame, and then re-tighten the second positioning bolts after the adjustment to achieve the effective purpose of facilitating the adjustment of the focal length. S6. During processing, the lamp body above projects the light source shape of the workpiece to be processed downward. And to be more obvious, by changing the cost and structure of the semiconductor material inside the lamp body, it emits a yellow or red light source. The light source projects on the base platform to form the workpiece clamping range, prompting the clamping personnel not to clamp beyond the range.

[0007] Working principle: When in use, select a metal template and process holes for workpieces of different shapes on the template so that the holes on the template can be consistent with the shapes of various workpieces. When processing workpieces in the same batch, select a template with the same shape as the workpiece to be processed, install the template at the light source opening position of the lamp body, and lock and fix it to ensure the stability of the template during use. And when replacing workpieces of different shapes subsequently, only need to remove and replace the internal template together. Install the adjusting plate on the movable frame, move the adjusting plate to a suitable position, and lock it with three positioning bolts. Then install the lamp body inside the two lamp body mounting seats and lock it with two positioning bolts at both ends. Conduct a preliminary debugging of the lamp body. The lamp body is designed in a cylindrical shape, and an LED strong light source is installed inside the cylindrical lamp body to provide light with sufficient brightness. The mold is located in front of the light source. Since the middle part of the mold is the designated hollow shape of the workpiece to be processed, a specific pattern is formed when the light passes through. The light emits from the light source, propagates in a straight line, and passes through the mold to form a light and shadow consistent with the shape of the mold. Due to the different sizes of the workpieces, adjustment still needs to be made after the lamp body is installed. When dealing with workpieces of the same shape but different sizes, only need to loosen the two positioning bolts so that the lamp body can be adjusted up and down inside the lamp body mounting frame, and then tighten the two positioning bolts again after the adjustment is completed to achieve the effective purpose of facilitating the adjustment of the focal length. During processing, the lamp body above projects the light source shape of the workpiece to be processed downward. And to be more obvious, by changing the cost and structure of the semiconductor material inside the lamp body, it emits yellow or red light. The light source projects on the base platform to form the workpiece clamping range, prompting the clamping personnel not to clamp beyond the range.

[0008] (III) Beneficial effects The present invention provides a positioning and loading guiding mechanism and method for a flexible production line. It has the following beneficial effects: 1. By installing the irradiation lamp body assembly directly above the manual loading station in the present invention, the template inside the lamp body is of a specified shape. After adjusting the focal length, it passes through the mold to form a light and shadow consistent with the shape of the mold, which can prompt the clamping personnel not to clamp beyond the range, improving the safety of the device. At the same time, a strong light source is projected inside the lamp body, and the profiling lamp shade can replace the expensive vision camera prompting mechanism. Brief description of the drawings

A workpiece 11 is arranged on the base platform 12. The shape of the workpiece 11 has various types and can be selected according to actual processing. At both ends below the middle of the mounting frame 1, brackets 10 are bolted. Through the brackets 10, the entire lamp body assembly can be installed directly above the manual loading position for use. The inner ends of the brackets 10 are also bolted with a cross beam 6. By installing the cross beam 5, the stability of the lamp body assembly during use can be improved. A movable frame 3 is arranged outside the cross beam 6. One end of the movable frame 3 close to the bracket 10 is provided with a plurality of screw holes, and a plurality of first positioning bolts 2 are screwed to the outer end of the movable frame 3 through the screw holes. The bottom of the movable frame 3 is slidably connected with an adjusting plate 4. The first positioning bolts 2 can lock and install the movable frame 3 on the bracket 10. Similarly, the movable frame 3 can also adjust its position on the bracket 10, and after the adjustment is completed, it can be re-locked through the first positioning bolts 2; A positioning plate is arranged at the connection between the adjusting plate 4 and the movable frame 3. A third positioning bolt 9 is screwed to the positioning plate and the adjusting plate 4. The inner end of the adjusting plate 4 is fixedly connected with a lamp body mounting seat 5. A lamp body 7 is correspondingly installed inside the lamp body mounting seat 5. Two groups of second positioning bolts 8 are screwed to both ends outside the lamp body mounting seat 5. The inner ends of the second positioning bolts 8 are in contact with the lamp body 7. A socket 13 is fixedly connected to the cross beam 6, and limiting members 14 are installed inside the two groups of movable frames 3. The adjusting plate 4 slides at the bottom of the movable frame 3. Its main function is to adjust the distance between the two lamp bodies 7. At the same time, after the adjustment is completed, it can be locked through the third positioning bolts 9. The function of the second positioning bolts 8 is to lock and install the lamp body 7, and the focal length can be adjusted by lifting and adjusting the lamp body 7. The socket 13 at the rear end can be electrically connected to the two lamp bodies 7 to supply power to the lamp bodies 7. The lamp bodies 7 project strong light sources inside and are imitation-shaped lamp covers, which can replace expensive vision camera prompting mechanisms.

[0013] A positioning and feeding guiding method for a flexible production line, comprising the following steps: S1. Select a metal template, and process holes for workpieces 11 of different shapes on the template so that the holes on the template can be consistent with the shapes of various workpieces 11; S2. When processing workpieces 11 of the same batch, select a template with the same shape as the workpiece 11 to be processed, install the template at the light source opening position of the lamp body 7, and lock and fix it to ensure the stability of the template during use. And when replacing workpieces of different shapes subsequently, only the internal template needs to be removed and replaced together; S3. Install the adjusting plate 4 on the movable frame 3, move the adjusting plate 4 to a suitable position, and lock it with the positioning bolt three 9. Then install the lamp body 7 inside the two lamp body mounting seats 5, and lock it at both ends with the positioning bolt two 8; S4. Conduct preliminary debugging on the lamp body 7. The lamp body 7 is designed in a cylindrical shape, and an LED strong light source is installed inside the cylindrical lamp body 7 to provide light with sufficient brightness. The mold is located in front of the light source. Since the middle part of the mold is the specified hollow shape of the workpiece to be processed, a specific pattern is formed when the light passes through. The light emits from the light source, propagates in a straight line, and passes through the mold to form a light and shadow consistent with the shape of the mold; S5. Since the sizes of the workpieces 11 are different, adjustment still needs to be made after the lamp body 7 is installed. When dealing with workpieces 11 of different sizes but the same shape, only the positioning bolt two 8 needs to be loosened to enable the lamp body 7 to be adjusted up and down inside the lamp body mounting frame 5. And after the adjustment is completed, the positioning bolt two 8 is tightened again to lock it, so as to achieve the effective purpose of facilitating the adjustment of the focal length; S6. During processing, the lamp body 7 above projects the light source shape of the workpiece to be processed downward. And for greater visibility, by changing the cost and structure of the semiconductor material inside the lamp body 7, it emits a yellow or red light source. The light source projects on the base platform 12 to form the clamping range of the workpiece 11, prompting the clamping personnel not to clamp beyond the range.

The scope of the present invention is defined by the appended claims and their equivalents.
