[0002] Wheelchair protection components may include wheelchair guards, armrests, brake systems, backrests, footrests / footrests and other components, which together constitute a safe, comfortable and convenient wheelchair use environment. Due to different wheelchair styles and user needs, the specific configuration of the protection components will also vary. Common wheelchair guards may be made of plastic or metal sheets coated with sponge or other cushioning and protective materials. During the processing of the metal sheet of the wheelchair guard, in order to buffer the installation of protective materials and the subsequent connection and installation of the guard plate to the wheelchair frame, the metal sheet of the guard plate raw material is often bent to achieve the required shape to meet actual usage needs.

[0003] To achieve rapid, mass-produced production, bending machines are often used to bend metal sheets. Existing automated sheet metal bending machines have relatively simple processing operations. For example, they use an instrument arm to automatically process the sheet metal. Due to its structural limitations, the instrument arm can only deliver the sheet metal and cannot flip the sheet metal or swap its ends. This lacks diverse processing methods and flexible processing effects. Furthermore, existing automated sheet metal bending machines lack automated inspection mechanisms for various aspects of sheet metal processing before and after processing, which is not conducive to improving product yield and production efficiency.

The two rotating blocks 7 The upper and lower ends are fixedly connected by a connecting plate 8, a first motor 9 is fixed to the side of one of the moving blocks 6, and the output end of the first motor 9 passes through the moving block 6 and is coaxially fixed to the rotating block 7. When the first motor 9 is started, the two rotating blocks 7 can be controlled to rotate. A clamping and conveying mechanism is provided on each of the two rotating blocks 7. Two second electric rods 10 and a third electric rod 12 are vertically fixed on opposite sides of the two connecting plates 8. The two second electric rods 10 are symmetrically arranged on both sides of the third electric rod 12. A strength detection mechanism is provided at the telescopic end of the second electric rod 10, and a suction cup mechanism is provided at the telescopic end of the third electric rod 12. Four plate edge detection mechanisms are provided on each of the two connecting plates 8;

[0033] A loading conveyor belt 13 is provided between the upper ends of the two fixing seats 4. The loading conveyor belt 13 is used to transport the metal plate 11 to be processed. A feeding mechanism and a plate flatness detection mechanism are provided on the loading conveyor belt 13.

[0034] As a technical optimization solution of the present invention, the clamping and conveying mechanism includes two electric push rods 15, and the two electric push rods 15 are respectively fixedly connected to the sides of the two rotating blocks 7 vertically. The telescopic ends of the electric push rods 15 pass through the rotating block 7 and are fixedly connected to a rectangular block 16. The electric push rods 15 are started synchronously to control the movement of the rectangular block 16. An infrared positioning sensor is fixed on the upper side of the rectangular block 16, and the infrared positioning sensor is used to locate the position of the metal sheet 11. A cavity is provided on the side of the rectangular block 16 facing away from the rotating block 7, and a conveyor belt 17 is provided in the cavity, that is, a driving motor for driving the conveyor belt 17 is fixed on the rectangular block 16, and the driving motor is used to drive the connecting shaft of the conveyor belt 17. When the electric push rods 15 at both ends are started, the conveyor belts 17 at both ends can separate and clamp the metal sheet 11. The conveyor belts 17 at both ends clamp the two ends of the metal sheet 11 and can perform a conveying operation on the metal sheet 11.

[0035] As a technical optimization solution of the present invention, the strength testing mechanism includes a clamping block 18 fixed to the telescopic end of the second electric rod 10. Activating the second electric rod 10 controls the movement of the clamping block 18, with the upper and lower corresponding clamping blocks 18 clamping the metal sheet 11. The clamping block 18 is strip-shaped, with a cylindrical block 19 fixed in the middle. A wireless rebound hammer is vertically fixed inside the cylindrical block 19. The wireless rebound hammer, similar to the existing ZC3-B model, can test the strength of the metal sheet 11, with its end extending beyond the end face of the cylindrical block 19.

[0036] As a technical optimization solution of the present invention, a laser distance sensor is provided between the clamping block 18 and the second electric rod 10. The laser distance sensor is the same as the existing sensor model STP23 and is used to detect distance changes. When the clamping blocks 18 at the upper and lower ends clamp the metal sheet 11, the distance changes during clamping are detected, and the thickness of the metal sheet 11 can be measured. In addition, an inverted L-shaped support frame is fixed at both ends of the clamping block 18, and a fourth electric rod 20 is vertically fixed on the inverted L-shaped support frame. The telescopic end of the fourth electric rod 20 passes through the inverted L-shaped support frame and is rotatably connected to a rubber wheel 21. When the fourth electric rod 20 is activated, it can drive the rubber wheel 21 to telescopically move, so that the rubber wheel 21 can be abutted against the surface of the metal sheet 11. The upper and lower corresponding rubber wheels 21 can effectively ensure the stability of the metal sheet 11 between them without affecting the movement of the metal sheet 11.

[0037] As a technical optimization solution of the present invention, the suction cup mechanism includes a rectangular frame 22 fixed to the telescopic end of the third electric rod 12. A suction cup rack 23 is provided on the opposite side of the two rectangular frames 22, and a number of suction cups 24 are fixed on the suction cup rack 23. The third electric rod 12 moves with the corresponding suction cups 24 in accordance with the control, and the corresponding suction cups 24 above and below can effectively clamp the metal sheet 11 in between.

[0038] As a technical optimization solution of the present invention, a rectangular frame 22 is rotatably connected to the suction cup frame 23, a second motor 25 is fixed in the rectangular frame 22, and the output end of the second motor 25 passes through the rectangular frame 22 and is coaxially fixedly connected to the suction cup frame 23. The second motor 25 is used to control the rotation. When several corresponding suction cups 24 above and below clamp the metal sheet 11 between them, the second motor 25 is started, which can control the rotation of the metal sheet 11 and realize the swapping of the two ends of the metal sheet 11.

[0039] As a technical optimization solution of the present invention, the plate edge detection mechanism includes a fifth electric rod 26 fixedly connected to the connecting plate 8. The four fifth electric rods 26 on the connecting plate 8 are arranged symmetrically in a matrix. The telescopic end of the fifth electric rod 26 is fixed with a connecting block, and the two ends of the connecting block are vertically fixed with a retraction rod 27. The fifth electric rod 26 is used to control the movement of the connecting block and the corresponding two retraction rods 27. The retraction rod 27 is provided with a pressure sensor inside. The pressure sensor is the same as the existing model FC-13 pressure sensor. The pressure sensor is located at the bottom of the retraction rod 27. A spring is provided between the pressure sensor and the extension rod inside the retraction rod 27. The spring is fixed to the extension rod and is not squeezed in the normal state. The telescopic end of the retraction rod 27 is fixed with a detection block 28. The two adjacent detection blocks 28 are arranged at an angle, and the inclined ends of the two detection blocks 28 are close to each other. The inclined detection block 28 can effectively correspond to the bending part of the metal plate 11 after the bending process.

[0040] As a technical optimization solution of the present invention, a finished product conveyor belt 14 is provided below the loading conveyor belt 13. The finished product conveyor belt 14 is parallel to the loading conveyor belt 13. The width of the finished product conveyor belt 14 is the same as the distance between the two fixed seats 4. The finished product conveyor belt 14 is used to transport materials, and the surface of the finished product conveyor belt 14 is rubber, which can effectively buffer the impact force of falling materials.

[0041] As a technical optimization solution of the present invention, the feeding mechanism includes two telescopic cylinders 29 symmetrically arranged on the loading conveyor belt 13. The two telescopic cylinders 29 are arranged horizontally and are fixedly connected to the loading conveyor belt 13 through a connecting seat, that is, the two telescopic cylinders 29 are in the same direction as the loading conveyor belt 13. The telescopic ends of the two telescopic cylinders 29 are fixed with suction nozzles 30, and there is a gap between the suction nozzles 30 and the loading conveyor belt 13. When the loading conveyor belt 13 transports the metal sheet 11 to the bottom of the two suction nozzles 30, there is a gap between the suction nozzles 30 and the metal sheet 11. At this time, the two suction nozzles 30 are started to adsorb the metal sheet 11, and then the two telescopic cylinders 29 are started to move the adsorbed metal sheet 11 to the front end.

[0042] As a technical optimization solution of the present invention, the plate flatness detection mechanism includes a support bar 31 fixedly arranged on the feeding conveyor belt 13, and the two ends of the support bar 31 correspond to the two sides of the feeding conveyor belt 13. A plurality of scrapers 32 are inclined at the bottom of the support bar 31, and the plurality of scrapers 32 are rotatably connected to the support bar 31. A touch button 33 is provided between the scraper 32 and the support bar 31, and there is a gap between the touch button 33 and the scraper 32. When the metal plate 11 is conveyed, the metal plate 11 passes through the lower ends of the plurality of scrapers 32. If the surface of the metal plate 11 is uneven and there are some protrusions, the scraper 32 at the corresponding position will be squeezed to cause it to rotate, and the scraper 32 will be squeezed to the touch button 33, thereby detecting whether the flatness of the metal plate 11 meets the processing requirements.

[0043] When the present invention is in use, the metal sheet 11 is placed at one end of the loading conveyor belt 13, and the loading conveyor belt 13 conveys the metal sheet 11. A number of positioning rollers are evenly provided on the side of the upper end of the loading conveyor belt 13. The several positioning rollers on both sides effectively limit the two ends of the metal sheet 11 to ensure the stability of its conveying process.

[0044] During the conveying process, when the metal sheet 11 passes the lower ends of several scrapers 32, if there are some protrusions on the surface of the metal sheet 11, and the protrusions press against the scrapers 32 at the corresponding positions, and also cause the scrapers 32 to rotate, so that the scrapers 32 press against the touch buttons 33, then it is detected that the flatness of the metal sheet 11 does not meet the processing requirements, and it will not be processed. The metal sheet 11 will be directly conveyed to the finished product conveyor 14 and finally discharged by the finished product conveyor 14. If the metal sheet 11 meets the processing requirements, it will continue to be conveyed to the front end of the feeding conveyor 13 and stop. At this time, the metal sheet 11 is located below the two suction nozzles 30. The two suction nozzles 30 are activated to suck and fix the metal sheet 11. Then, the two telescopic cylinders 29 are synchronously activated to move the sucked metal sheet 11 to the front end. At this time, the two first electric rods 5 control the moving block 6 and the corresponding rotating block 7 to move to one end close to the feeding conveyor belt 13, and the two connecting plates 8 are in corresponding upper and lower positions. The metal sheet 11 is conveyed between the two connecting plates 8. At this time, the second electric rods 10 located above and below are started synchronously, controlling the corresponding upper and lower clamping blocks 18 to clamp the metal sheet 11, effectively ensuring the stability of the metal sheet 11.

[0045] During the clamping process of the clamping block 18, the wireless rebound test rod inside the cylindrical block 19 presses against the surface of the metal sheet 11 and contracts, detecting the strength of the metal sheet 11. The four wireless rebound test hammers simultaneously calculate an average value, and the test data is recorded. Simultaneously, as the upper and lower clamping blocks 18 clamp the metal sheet 11, laser distance sensors on the clamping blocks 18 detect the change in distance during clamping, thereby measuring the thickness of the metal sheet 11. If the strength or thickness of the metal sheet 11 does not meet the processing requirements, processing is canceled, the clamping is canceled, and the sheet 11 is conveyed onto the finished product conveyor belt 14. The two first electric rods 5 then control the moving block 6 and the corresponding rotating block 7 to move closer to the machine platform 1, bringing the metal sheet 11 closer to the machine platform 1. Simultaneously, the electric push rods 15 at both ends are activated, causing the conveyor belts 17 at both ends to clamp the ends of the metal sheet 11, thereby securing it and aligning it to the center position, effectively positioning it. After the conveyor belts 17 at both ends clamp the two ends of the metal sheet 11, the second electric rod 10 controls the corresponding clamping block 18 to retract, and the fourth electric rod 20 on the clamping block 18 starts and drives the rubber wheel 21 to press against the surface of the metal sheet 11. The upper and lower corresponding rubber wheels 21 effectively ensure the stability of the metal sheet 11 in between without affecting the movement of the metal sheet 11.

[0046] After completing the above steps, the bending process can be performed. During the bending process, the conveyor belts 17 at both ends clamp the two ends of the metal sheet 11 and start to convey the metal sheet 11. During the conveying process, the infrared positioning sensor on the upper side of the rectangular block 16 locates the position of the metal sheet 11, so that the metal sheet 11 is accurately conveyed between the upper mold 2 and the lower mold 3. The upper mold 2 and the lower mold 3 then perform the bending process on the metal sheet 11. At the same time, during processing, when one end of the metal sheet 11 is compressed, the other end will tilt up. At this time, the second electric rods 10 at the upper and lower ends can extend or contract as the metal sheet 11 tilts up, effectively ensuring the stable processing of the metal sheet 11 and improving the processing efficiency of the metal sheet 11.

[0047] The present invention can perform flexible and diverse processing, and can perform U-shaped bending processing. After the bending processing of one side of the metal sheet 11 is completed, the conveyor belts 17 at both ends are started to withdraw the metal sheet 11. The two first electric rods 5 control the overall movement of the moving block 6 and the corresponding rotating block 7 to the middle position between the machine table 1 and the feeding conveyor belt 13, that is, the metal sheet 11 is located between the machine table 1 and the feeding conveyor belt 13. At this time, the two upper and lower corresponding third electric rods 12 are started, and the corresponding suction cups 24 are controlled to move, so that the corresponding upper and lower suction cups 24 clamp the metal sheet 11 in between. Then, the electric push rods 15 at both ends drive the conveyor belts 17 to leave both ends of the metal sheet 11, and the fourth electric rods 20 on the clamping blocks 18 also retract and leave. Then, the first motor 9 controls the overall rotation of the rotating block 7 to an inclined state, that is, the metal sheet 11 is rotated to an inclined state. The inclined state provides sufficient space for the position adjustment of the metal sheet 11 and does not occupy a large space. Then, the second motor 25 is started to control the corresponding suction cup holder 23 to rotate 180 degrees, and then control the rotation of the metal sheet 11, and the two ends of the metal sheet 11 are swapped. Then, the conveyor belts 17 at both ends clamp both ends of the metal sheet 11 again, and the rubber wheels 21 extend to ensure the stability of the metal sheet 11 again. The two first electric rods 5 control the overall movement of the moving block 6 and the corresponding rotating block 7 to the position of the machine table 1, that is, the metal sheet 11 is close to the machine table 1. The conveyor belt 17 drives the metal sheet 11 to move. At this time, the bending processing of the other side of the metal sheet 11 can be performed, and finally the finished product shape of the U-shaped is processed, realizing a flexible and diverse processing method and an automated processing effect.

[0048] The present invention can perform flexible and diverse processing, and can perform Z-shaped bending processing. After the bending processing of one side of the metal sheet 11 is completed, the conveyor belts 17 at both ends are started to withdraw the metal sheet 11. The two first electric rods 5 control the overall movement of the moving block 6 and the corresponding rotating block 7 to the middle position between the machine table 1 and the feeding conveyor belt 13, that is, the metal sheet 11 is located between the machine table 1 and the feeding conveyor belt 13. Then, the first motor 9 controls the overall rotation of the rotating block 7 by 180 degrees, that is, controls the metal sheet 11 to turn over one side. After the turning over is completed, the two first electric rods 5 control the overall movement of the moving block 6 and the corresponding rotating block 7 to a position close to the machine table at 1, that is, the metal sheet 11 is close to the machine table 1. At this time, the bending processing operation of the other side of the metal sheet 11 can be performed, and finally the finished product shape of the Z-shaped is processed, realizing a flexible and diverse processing method and an automated processing effect.

[0049] After completing the U-shaped or Z-shaped processing, the bending part of the metal sheet 11 can be inspected. By starting the four fifth electric rods 26, the fifth electric rods 26 control the movement of the connecting block and the corresponding two retraction rods 27, and the two detection blocks 28 located on both sides of the metal sheet 11 move and correspond to the two sides of the bending part of the metal sheet 11. The inclined detection blocks 28 can effectively correspond to the bending part after the bending process. The movement of the fifth electric rod 26 causes the detection block 28 to squeeze the part. When the squeezing reaches the set amount, the pressure sensor inside the retraction rod 27 performs pressure testing and records, thereby effectively judging whether the thickness of the bending part meets the requirements. By recording the data during the production of multiple batches of metal sheets 11, judgments can be made based on the data. If the data fluctuates greatly, the equipment can be adjusted to effectively improve production efficiency.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
