Description

Technical Field

[0001] This invention relates to the field of flexible workstations, and more particularly to an automatically controlled flexible workstation. Background Technology

[0002] CNC lathes, also known as computer numerical control lathes, are the most widely used and prevalent type of CNC machine tool in China. CNC machine tools automatically machine parts according to pre-programmed machining procedures. We compile the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions into a machining program sheet according to the instruction codes and program format specified by the CNC machine tool. This program sheet is then recorded on a control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to machine the parts.

[0003] For related technologies, please refer to Chinese invention patent CN116276262A, which discloses a control system for a flexible workstation, including control components. The control components include a control host, a robotic arm, a robotic hand, a placement slot, a recognition camera, a mounting base, an infrared detector, a hopper, a beam-type placement frame, a cutter head compartment, two cutter head holders, two limit blocks, and cutter head slots. The two limit blocks are symmetrically and fixedly connected to the inner walls of the hopper on opposite sides. The lower surface of the beam-type placement frame is attached to the upper surface of the two limit blocks. The placement slots are evenly distributed on the upper surface of the beam-type placement frame. During operation, a forklift is first used to remove the beam-type placement frame, and then the parts are placed in the placement slots one by one. Then, the forklift is used again to place the beam-type placement frame into the hopper. The position of the beam-type placement frame is limited by the limit blocks. When the CNC equipment needs to be loaded, the robotic hand picks up the parts and moves them into the CNC equipment for loading and processing.

[0004] Regarding the aforementioned technologies, if the operator operates improperly during the process of moving parts into the hopper, the beam-type placement rack may shake, causing the parts to easily fall out of the placement slot. This necessitates the operator to reposition the parts, resulting in low equipment efficiency. Summary of the Invention

This facilitates operation by the staff and further solves the problem of low equipment efficiency.

[0020] 3. When multiple placement slots contain parts to be processed, the first torsion spring applies force to the cover plate, causing the cover plate to press down on the multiple parts, further limiting the parts and preventing them from shaking and falling out of the placement slots.

[0034] The following is combined with Figure 1 - Appendix Figure 12 The present invention will be described in further detail below.

[0035] This invention discloses an automatically controlled flexible workstation. (Refer to...) Figures 1 to 6The automatically controlled flexible workstation includes a base 1, a hopper 11, multiple placement racks 12, a robotic arm 13, and a mounting base 14. The hopper 11 is fixedly connected to the top of the base 1. The multiple placement racks 12 are arranged sequentially from top to bottom in the hopper 11. The top of each placement rack 12 has multiple placement slots 121. The robotic arm 13 is fixedly connected to the top of the base 1, and the mounting base 14 is fixedly connected to the robotic arm 13. Multiple sets of fixing mechanisms 2 for limiting the position of parts are installed on the placement racks 12. The multiple sets of fixing mechanisms 2 are respectively arranged corresponding to the placement slots 121. The fixing mechanism 2 includes a bidirectional screw 21 and two fixing plates 22. The bidirectional screw 21 is rotatably installed in the placement slot. On the inner wall of 121, two fixing plates 22 are slidably installed on the inner wall of the placement groove 121. The two ends of the bidirectional screw 21 are respectively inserted into the fixing plates 22 and are threadedly connected to the fixing plates 22. A first rack 23 is slidably installed in the placement groove 121. A first gear 211 that meshes with the first rack 23 is fixedly connected to the bidirectional screw 21. A first spring 24 is fixedly connected between the first rack 23 and the inner wall of the placement groove 121. An iron block 25 is fixedly connected to the first rack 23. An electromagnet 26 that works with the iron block 25 is fixedly connected in the placement groove 121. A control component for energizing and de-energizing the electromagnet 26 is installed on the placement rack 12.

[0036] When a part is placed in the placement slot 121, the control unit is activated to energize the electromagnet 26. The electromagnet 26 attracts the iron block 25, which in turn moves the first rack 23. The first rack 23 then rotates the first gear 211, which in turn rotates the bidirectional screw 21. The bidirectional screw 21 causes the two fixing plates 22 to move closer together, clamping and fixing the part. This prevents the part from shaking and falling out of the placement slot 121 during the movement of the placement rack 12, thus solving the problem of low equipment efficiency.

[0037] Reference Figures 4 to 7A storage battery, electrically connected to an electromagnet 26 via a wire, is fixedly connected to the placement rack 12. A control groove 122 is provided on the inner bottom surface of the placement groove 121. The control component includes a control block 27, which is slidably installed in the control groove 122 and can contact the part. A second spring 28 is fixedly connected between the control block 27 and the inner bottom surface of the control groove 122. A first switch, electrically connected to the electromagnet 26 via a wire, is provided on the control block 27. A second switch, electrically connected to the storage battery via a wire, is provided on the inner wall of the control groove 122. The first and second switches are used in conjunction. A separation component for separating the second switch from the first switch is installed in the control groove 122. During the process of placing the part into the placement groove 121, the part presses the control block 27, compressing the second spring 28. The control block 27 drives the first switch to move. When the first switch contacts the second switch, the storage battery energizes the electromagnet 26, thus fixing the part. This facilitates operation by the staff and further solves the problem of low equipment efficiency.

[0038] Reference Figures 2 to 7 The separation component includes a separation rod 29, which passes through the side wall of the placement frame 12 and can contact the mounting base 14. The separation rod 29 extends into the control groove 122. A second switch is disposed on the separation rod 29. A third spring 20 is fixedly connected between the separation rod 29 and the inner wall of the control groove 122. When it is necessary to load the parts, the robotic arm 13 drives the mounting base 14 to move, and the mounting base 14 drives the robotic arm to move. At the same time, the mounting base 14 can push the separation rod 29 to move, compressing the third spring 20. The separation rod 29 drives the second switch to move, so that the second switch separates from the first switch, de-energizing the electromagnet 26. The first spring 24 drives the first rack 23 to move, so that the two fixing plates 22 move away from each other, releasing the restriction on the parts and making it easier for the robotic arm to pick up the parts.

[0039] Reference Figures 4 to 9Locking mechanisms 3 are installed at both ends of the placement rack 12. Each locking mechanism 3 includes a mounting block 31, which is mounted on the placement rack 12. A locking mounting groove is formed on the side wall of the mounting block 31, and a locking spring 32 is fixedly connected to the inner wall of the locking mounting groove. A locking block 33 is slidably installed in the locking mounting groove, and the locking spring 32 is fixedly connected to the locking block 33. A locking insertion groove for inserting the locking block 33 is formed on the side wall of the hopper 11. A locking inclined surface 331 is formed on the end face of the locking block 33 away from the locking spring 32, and the locking inclined surface 331 can contact the side of the hopper 11. A sliding groove 123 is formed on the end face of the placement rack 12, and the mounting block 31 is slidably installed in the sliding groove 123. The placement rack 12 is equipped with... A drive component is used to move the mounting block 31. When multiple placement slots 121 contain parts to be processed, the drive component drives the mounting block 31 to move, causing the locking block 33 to extend from the sliding slot 123. Then, the placement rack 12 is placed into the hopper 11. When the locking inclined surface 331 contacts the side of the hopper 11, the locking block 33 retracts into the locking mounting slot, compressing the locking spring 32. When the locking block 33 is opposite to the locking insertion slot, the locking spring 32 pushes the locking block 33 into the locking insertion slot, locking the placement rack 12 and completing the connection between the placement rack 12 and the hopper 11. This facilitates operation by the staff and further solves the problem of low equipment efficiency.

[0040] Reference Figures 4 to 9 A fourth spring 34 is fixedly connected between the mounting block 31 and the inner wall of the sliding groove 123. An airflow channel 124 communicating with the sliding groove 123 is formed in the placement frame 12. The driving component includes an abutment rod 35, which is slidably placed in the airflow channel 124. The four side walls of the abutment rod 35 are all in contact with the inner wall of the airflow channel 124. The abutment rod 35 extends into the sliding groove 123 and contacts the mounting block 31. Airbags 36 are fixedly connected to multiple placement grooves 121. Multiple airbags 36 are connected to the airflow channel 124 through pipes. A compression plate 37 is fixedly connected to the first rack 23. The extrusion plate 37 contacts the airbag 36. During the movement of the first rack 23, the first rack 23 drives the extrusion plate 37 to move, and the extrusion plate 37 extrudes the airbag 36. The gas in the airbag 36 enters the airflow channel 124 through the pipe and pushes the abutment rod 35 to move. The abutment rod 35 pushes the mounting block 31 to move. When multiple placement slots 121 are filled with parts to be processed, multiple extrusion plates 37 extrude the airbag 36. The mounting block 31 drives the locking block 33 to extend from the sliding slot 123, which facilitates the connection between the placement rack 12 and the hopper 11.

[0041] Reference Figures 4 to 12A cover pressing mechanism 4 is installed on the placement rack 12. The cover pressing mechanism 4 includes a flipping shaft 41, which is rotatably mounted on the placement rack 12. A cover pressing plate 42 is fixedly connected to the flipping shaft 41 and can contact multiple parts. A first torsion spring 43 is sleeved on the flipping shaft 41. One end of the first torsion spring 43 is fixedly connected to the placement rack 12, and the other end of the first torsion spring 43 is fixedly connected to the flipping shaft 41. A toothed plate 44 is fixedly connected to the inner wall of the hopper 11. Multiple teeth 45 are hinged to the bottom of the toothed plate 44. The hinge shaft installed in the teeth 45 is located on the side of the teeth 45 away from the mounting base 14. A second torsion spring 46 is sleeved on the hinge shaft installed in the teeth 45. A cover pressing plate 46 that can contact multiple teeth is fixedly connected to the flipping shaft 41. The second gear 411 engages with the teeth 45. When multiple placement slots 121 contain parts to be processed, the first torsion spring 43 applies force to the cover plate 42, causing the cover plate 42 to press down on the multiple parts, further limiting the parts and preventing them from shaking and falling out of the placement slots 121. During the process of placing the placement rack 12 into the hopper 11, the placement rack 12 drives the second gear 411 to move. When the second gear 411 engages with multiple teeth 45, the engagement of the multiple teeth 45 can drive the second gear 411 to rotate. The second gear 411 drives the flip shaft 41 to rotate, and the flip shaft 41 drives the cover plate 42 to rotate, releasing the limitation on the parts and making it easier for the robot to pick up the parts.

[0042] Reference Figures 10 to 11 A fixing block 125 is fixedly connected to the placement rack 12. A limiting mechanism 5 for positioning the cover plate 42 is installed on the fixing block 125. A limiting installation groove is opened on the side wall of the fixing block 125. The limiting mechanism 5 includes a limiting spring 51 fixedly connected to the inner wall of the limiting installation groove. A limiting block 52 is slidably installed in the limiting installation groove. The limiting spring 51 is fixedly connected to the limiting block 52. A limiting insertion groove for the limiting block 52 to be inserted is opened on the side wall of the cover plate 42. A transmission component is installed on the mounting block 31. The mounting block 31 can drive the limiting block 52 to disengage from the limiting insertion groove through the transmission component. After the cover plate 42 is separated from the part, the limiting spring 51 pushes the limiting block 52 to be inserted into the limiting insertion groove. The limiting block 52 locks the cover plate 42. When the part is placed again, it is not necessary to open the cover plate 42 from the placement groove 121.

[0043] Reference Figures 5 to 11The transmission component includes an L-shaped stop bar 53 fixedly connected to the mounting block 31. The L-shaped stop bar 53 extends to the outside of the placement frame 12 and can slide on the placement frame 12. A pull rod 54 is fixedly connected to the end of the limiting block 52 away from the cover plate 42. The pull rod 54 extends to the outside of the fixing block 125. A pull plate 55 is fixedly connected to the end of the pull rod 54 away from the limiting block 52. The L-shaped stop bar 53 can contact the pull plate 55. After all the parts are removed, the fourth spring 34 drives the mounting block 31 and the locking block 33 to retract into the sliding groove 123. The mounting block 31 drives the L-shaped stop bar 53 to move. The L-shaped stop bar 53 separates from the pull plate 55, and the limiting spring 51 can push the limiting block 52 to move.

[0044] Reference Figures 3 to 5 On the two inner walls of the hopper 11, there are two fixedly connected receiving plates 15. The top of each of the two receiving plates 15 is provided with a sliding groove 151. The end of the sliding groove 151 away from the robotic arm 13 is provided with an opening. The two inner walls of the opening end of the sliding groove 151 are formed with guide slopes 152. The distance between the two guide slopes 152 near the robotic arm 13 is smaller than the distance between the two ends away from the robotic arm 13. The two ends of the bottom of the placement frame 12 are fixedly connected with sliders 126 placed in the sliding grooves 151. The two guide slopes 152 can guide the sliders 126, which facilitates the connection between the placement frame 12 and the hopper 11.

[0045] Reference Figures 3 to 5 A retaining spring 16 is fixedly connected to the inner wall of the slide 151 near the end of the robotic arm 13. The retaining spring 16 can abut against the slider 126. When the locking block 33 disengages from the locking insertion slot, the retaining spring 16 pushes the placement rack 12 to move, making it easy to remove the placement rack 12.

[0046] The implementation principle of an automatically controlled flexible workstation according to an embodiment of the present invention is as follows: When a part needs to be processed, the part is first placed in the placement slot 121. The part presses against the control block 27, which compresses the second spring 28. The control block 27 drives the first switch to move. When the first switch contacts the second switch, the battery energizes the electromagnet 26, which attracts the iron block 25. The iron block 25 drives the first rack 23 to move, which in turn drives the bidirectional screw 21 to rotate. The bidirectional screw 21 drives the two fixing plates 22 to move closer together, clamping and fixing the part. At the same time, the first rack 23 drives the extrusion plate 37 to move, which then extrudes the airbag 36. The gas in the airbag 36 enters the airflow channel 124 through the pipe and pushes the abutment rod 35 to move. The abutment rod 35 pushes the mounting block 31 to move. When multiple placement slots 121 contain parts to be processed, multiple extrusion plates 37 extrude the airbag 36. The mounting block 31 drives the locking block 33 to extend out of the sliding slot 123, and the mounting block 31 drives the L-shaped stop bar 53 to move. The L-shaped stop bar 53 drives the pull plate 55 to move. The pull plate 55 drives the pull rod 54 to move. The pull rod 54 drives the limiting block 52 to move, causing the limiting block 52 to disengage from the limiting insertion slot. The first torsion spring 43 applies force to the cover plate 42, causing the cover plate 42 to press on top of multiple parts and limit the parts.

[0047] When the placement rack 12 is placed into the hopper 11, and the locking ramp 331 contacts the side of the hopper 11, the locking block 33 retracts into the locking mounting groove, compressing the locking spring 32. When the locking block 33 is aligned with the locking insertion groove, the locking spring 32 pushes the locking block 33 into the locking insertion groove, locking the placement rack 12 and completing the connection between the placement rack 12 and the hopper 11. Simultaneously, the placement rack 12 drives the second gear 411 to move. When the second gear 411 meshes with multiple teeth 45, the multiple teeth 45 can drive the second gear 411 to rotate, and the second gear 411 drives the flipping mechanism. The rotating shaft 41 rotates, and the flipping shaft 41 drives the cover plate 42 to rotate, releasing the restriction on the parts. When the parts need to be loaded, the robotic arm 13 drives the mounting base 14 to move, and the mounting base 14 drives the robotic arm to move. At the same time, the mounting base 14 can push the separating rod 29 to move, compressing the third spring 20. The separating rod 29 drives the second switch to move, so that the second switch separates from the first switch, de-energizing the electromagnet 26. The first spring 24 drives the first rack 23 to move, so that the two fixing plates 22 move away from each other, releasing the restriction on the parts, making it easier for the robotic arm to pick up the parts.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
