DETAILED DESCRIPTION

[0027] Reference Figures 1 to 8 The embodiments of the present invention are further described.

[0028] The present invention discloses a fully automatic bending device for brake pads and shims, comprising a frame 1 and a material picking device 2, a material storage device 3, a material positioning device 4, a bending device 5 and a material unloading device 6 arranged on the frame 1, wherein the material storage device 3 and the material unloading device 6 are respectively arranged on both sides of the material picking device 2, the material positioning device 4 is arranged at the front end of the material picking device 2, and the bending device 5 is located between the material positioning device 4 and the material unloading device 6. The material picking device 2 is used to place the material of the material storage device 3 on the material positioning device 4, and the material positioning device 4 transports the material to the bending device 5 to bend the material. After the bending is completed, the material positioning device 4 is reset and transported to the unloading device 6 through the material picking device 2 for unloading.

[0029] Furthermore, the material storage device 3 includes a driving base 30 that can slide back and forth along the direction of the material positioning device 4. Figure 3 As shown, the driving base 30 can be driven by a driving structure such as a cylinder or a screw drive. Two groups of symmetrically arranged storage bins 31 are arranged above the driving base 30. By arranging two groups of symmetrically arranged storage bins 31, the storage device 3 can store a large amount of materials and realize the function of non-stop loading. Specifically, when the material in one of the storage bins 31 is taken out, the driving base 30 drives another storage bin 31 to move to the bottom of the material taking suction nozzle 22 for taking materials, and then the worker can replenish the empty storage bin 31, thereby achieving the function of non-stop loading and improving the production efficiency. The storage bin 31 includes a storage base 310 and four adjustable side panels 36 arranged on the storage base 310. The four adjustable side panels 36 are mutually enclosed to form a storage cavity 319 for stacking materials. A loading push plate 32 is also embedded on the storage base 310. Two push rods 33 are arranged at a gap at the bottom of the loading push plate 32. The push rods 33 extend downward into the frame 1. A push plate 34 for driving the push rods 33 to slide upward is arranged in the frame 1. The push plate 34 is used to push the material upward to ensure that the material is always at the same height, so as to achieve stable material collection of the material collection device 2. The push plate 34 is driven by a driving member 35, such as Figure 3 As shown, the driving member 35 can be set to be a cylinder or a screw drive, and the cylinder or the screw is used to drive the push plate 34 to move up and down to achieve stable driving.

[0030] Furthermore, the four adjustable side panels 36 include two side panels 36, and a rear side panel 37 at both ends of the two side panels 36 and a movable side panel 38 arranged in an L shape. The two side panels 36, the rear side panel 37 and the movable side panel 38 can be quickly adjusted to accommodate materials of different lengths and widths for loading, which is very practical. A magnet 380 is arranged at the bottom of the movable side panel 38, and the movable side panel 38 can be fixed on the storage base 310 by adsorption of the magnet 380. The movable side panel 38 is fixed by the magnet 380 to facilitate workers to load materials. When loading, the movable side panel 38 can be removed and then the materials can be conveniently stacked between the two side panels 36. Finally, the movable side panel 38 is used to squeeze and flatten the materials to achieve flat stacking of the materials. In addition, multiple magnetic sheets can be set on the movable side plate 38. The magnetic force generated by the magnetic sheets can be used to partially magnetize the material, and the material can be separated by utilizing the effect of repulsion between the same level to prevent the material from sticking when being taken away, thereby greatly improving the stability of the material during absorption. In order to further prevent adhesion, a coating can be set on the inner walls of the two side plates 36 to prevent sticking.

[0031] The material storage base 310 is provided with two first sliding racks 311 arranged with a gap therethrough, and a first adjusting gear 312 is provided in the material storage base 310 and is located between the two first sliding racks 311. The first adjusting gear 312 is arranged in gear meshing with the two first racks, and a first hand wheel 313 for driving the first adjusting gear 312 to rotate is provided at the bottom of the material storage base 310, and connecting blocks 360 fixedly connected to the first racks are respectively provided on the two side plates 36, and a first sliding groove 314 slidingly matched with the connecting block 360 is provided on the material storage base 310. A second adjusting gear 315 is provided at the bottom of the base 310 relative to the movable side plate 38, and a second rack 316 is provided through the material storage base 310 and is located below the first rack and is vertically arranged with the first rack. The second rack 316 and the second adjusting gear 315 are gear-meshingly arranged, and a second hand wheel 317 for driving the second adjusting gear 315 to rotate is provided at the bottom of the material storage base 310, a connecting rod 370 fixedly connected to the second rack 316 is provided on the rear side plate 37, and a second sliding groove 318 slidably matched with the connecting rod 370 is provided on the material storage base 310.

[0032] like Figure 3As shown, when adjusting the storage bin 31, the first adjusting gear 312 is rotated by manually turning the first hand wheel 313. When the first adjusting gear 312 rotates, the first racks located on both sides of the first adjusting gear 312 will be forced to drive the two side panels 36 to slide inward or outward, thereby realizing rapid adjustment of the width of the side panels 36; the second adjusting gear 315 is rotated by manually turning the second hand wheel. When the second adjusting gear 315 rotates, the second racks 316 located on both sides of the second adjusting gear 315 will be forced to drive the rear side panels 37 to slide inward or outward, thereby realizing rapid adjustment of the length of the side panels 36, which is very time-saving and labor-saving to operate.

[0033] Furthermore, the material taking device 2 includes a driving rod 20 vertically arranged on the frame 1, an L-shaped material taking bracket 21 is arranged at the end of the driving rod 20, and a material taking nozzle 22 for taking materials is arranged at both ends of the material taking bracket 21, and a driving member 23 for driving the driving rod 20 to rotate and a driving member 3 24 for driving the driving rod 20 to slide up and down are arranged in the frame 1. Figure 2 As shown, the driving member 23 can use a servo motor in conjunction with a reducer to drive the driving rod 20 to rotate, and the driving member 3 24 can use a servo motor to drive the driving rod 20 to slide up and down. Alternatively, the driving member 23 can use a rotary cylinder to drive the driving rod 20 to rotate, and the driving member 3 24 can use a cylinder to drive the driving rod 20 to slide up and down.

[0034] Furthermore, the material positioning device 4 includes a first movable seat 40 that is slidable back and forth along the direction of the bending device 5, and a second movable seat 41 that is arranged on the first movable seat 40 and can slide back and forth along the vertical direction of the first movable seat 40. The first movable seat 40 and the second movable seat 41 can be driven by a cylinder or a screw drive. Support plates 42 are fixed on both sides of the second movable seat 41, and mounting plates 43 extending toward the material taking device 2 are fixed on the two support plates 42. A rotating plate 44 that rotates in coordination is arranged on the mounting plate 43, and two symmetrically arranged material clamping heads 45 are fixed on the rotating plate 44. The two material clamping heads 45 are used to clamp and position the material.

[0035] Furthermore, a rotating shaft 46 penetrating the bottom of the mounting plate 43 is provided at the bottom of the rotating plate 44, a servo motor 47 is provided between the two supporting plates 42, and a driving belt 48 for connecting the rotating shaft 46 is provided on the output shaft of the servo motor 47. The driving of the servo motor 47 enables the rotating plate 44 to be precisely controlled, with higher precision and greater stability.

[0036] Furthermore, the bending device 5 includes an inclined fixed bracket 50, and the fixed bracket 50 is sequentially provided with an upper driving cylinder 51, an upper guide block 52, a positioning block 53, a lower guide block 54 and a lower driving cylinder 55 from top to bottom. A horizontally protruding material placement protrusion 530 is extended from the upper end of the positioning block 53. A pressing rod 510 that is slidably matched with the upper guide block 52 is hinged on the output shaft of the upper driving cylinder 51, and the end of the pressing rod 510 is arranged in abutment with the material placement protrusion 530. A bending rod 550 that is slidably matched with the lower guide block 54 is hinged on the output shaft of the lower driving cylinder 55. A through groove 531 is provided on the material placement protrusion 530 for the bending rod 550 to pass through. The bending rod 550 is located on the inner side of the pressing rod 510 and is staggered, and a rotatably matched bending roller 551 is provided at the end of the bending rod 550.

[0037] Furthermore, the blanking device 6 includes a base 60 and a blanking guide plate 61 fixed on the base 60, and the blanking guide plate 61 is arranged to be inclined downward.

[0038] Furthermore, two material taking suction nozzles 22 are provided, and are fixed on the material taking bracket 21 with a gap therebetween. By providing two material taking suction nozzles 22, material taking can be more stable.

[0039] Working principle: When bending the material, Figure 1As shown, first, the material in the storage bin 31 is sucked by the material taking nozzle 22 of the material taking device 2, and then the driving rod 20 drives the material to be placed between the two clamping heads 45 of the rotating plate 44, and the two clamping heads 45 clamp the material in place. Then, the first moving seat 40 drives the material to slide to the bending device 5, where the material can be moved forward, backward, left and right by the cooperation of the first moving seat 40 and the second moving seat 41, and then the rotating plate 44 drives the material to rotate at multiple angles, so that multiple protrusions of the material to be bent can be placed in alignment with the material placement protrusion 530. When the protrusion of the material is located at the placing protrusion 530, the upper driving cylinder 51 drives the pressing rod 510 to slide downward to press the material against the placing protrusion 530, and then the lower driving cylinder 55 drives the bending rod 550 to slide upward. Since the bending rod 550 is located on the inner side of the pressing rod 510 and is staggered, the protrusion of the material will be resisted and bent upward to 90 degrees during the upward sliding process of the bending rod 550. When the protrusion is bent, the bending rod 550 is reset by the lower driving cylinder 55. When the multiple protrusions of the material have completed bending, the material is reset through the material positioning device 4. During the reset, the bent material can be sucked by the material picking nozzle 22, and the material will be driven to the top of the blanking guide plate 61 for unloading through the rotation of the driving rod 20. When the material picking nozzle 22 is unloading, since the material picking bracket 21 is arranged in an L shape, the next material can be taken out from the storage bin 31 and placed between the two clamping heads 45 during the unloading process of the material picking device 2 to achieve the effect of cyclic loading and unloading, thereby achieving the effect of fully automatic production.

[0040] In summary, the brake pad shim fully automatic bending equipment of the present invention can realize the fully automatic bending of the brake pad shim, improve the production efficiency of the enterprise, and the product quality is more stable and reliable, and also reduces the labor cost and production cost.
