[0037] Next, in conjunction with the accompanying drawings, the multi-station assembly machine for brush holder assembly and its assembly method provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0038] Embodiment 1:

[0039] As Figures 1 to 7 shown, the embodiment of the present application provides a multi-station assembly machine for brush holder assembly, including a disk 2 with a plurality of clamping tables 1, a pair of feeding components 3, a pair of bending components 4, and a discharging component 5. Each clamping table 1 is provided with a plurality of clamping frames 6 for respectively clamping the frame 100 and cooperatively bearing the brush box 200. A pair of feeding components 3 are used to hold the frame 100 and place the frame 100 one by one into the clamping frame 6 of the corresponding disk 2, and the bending component 4 is used to bend the fixing strip 300 on the frame 100.

[0040] Further, the feeding component 3 includes a vibrating disk 31, a sorting device 32, and a transfer device 33. The sorting device 32 is arranged at the discharge port 311 of the vibrating disk 31. The sorting device 32 moves the frame 100 out of the discharge port 311 of the vibrating disk 31, and the transfer device 33 clamps both ends of the frame 100 and transfers it into the clamping frame 6.

[0041] Further, the sorting device 32 includes a fixed table 321, on the top of which a sliding table 323 is slidably installed through a cylinder 322. One end of the sliding table 323 is provided with a receiving groove 324 corresponding to the discharge port 311 of the vibrating disk 31, and the other end is installed with a cylinder 325, and the piston rod of the cylinder 325 can extend into the receiving groove 324.

[0042] In this embodiment of the present application, due to the adoption of the above structure, asFigure 8 and 9 As shown in 9 , the brush holder assembled in the present application has four frames 100, which are arranged radially, symmetrically in pairs, and the axes of the two pairs of frames 100 are perpendicular to each other. Each feeding assembly 3 is only responsible for the feeding action of one pair of frames 100.

[0043] The disk 2 is driven by a motor to rotate, so that the clamping table 1 enters below the first feeding assembly 3. The vibrating disk 31 in the feeding assembly 3 operates, and the frame 100 is discharged from the outlet end into the accommodating groove 324. The second cylinder 325 acts, and its piston rod extends into the accommodating groove 324 to press the frame 100 therein. The first cylinder 322 acts, so that the sliding table 323 moves away from the discharge port 311 of the vibrating disk 31 and moves to below the transfer device 33. The piston rod of the second cylinder 325 retracts. At this time, the two ends of the frame 100 are blocked, and the transfer device 33 clamps the two ends of the frame 100 and transfers the frame 100 to the frame clamp 6 corresponding to the clamping table 1 at this time. At the same time, the second cylinder 325 acts, so that the sliding table 323 approaches the discharge port 311, and the above actions are repeated, so that the other frame clamp 6 located on the same extension line is also loaded with the frame 100. Then the disk 2 continues to rotate, so that the other pair of frame clamps 6 without loaded frames 100 move to the corresponding position of the next feeding assembly 3, and the above-mentioned frame 100 feeding operation is repeated until all four frame clamps 6 in the clamping table 1 are loaded with the frames 100. Then the disk 2 rotates, so that the clamping table 1 moves out of the second feeding assembly 3, and the brush box 200 is placed on the frame clamps 6 on the clamping table 1 manually. The fixing strips 300 on each frame 100 pass through the corresponding slots on the brush box 200. The disk 2 rotates, so that the clamping table 1 moves to below the first bending assembly 4. The first bending assembly 4 bends the fixing strips 300 on a pair of frames 100 located on the same straight line. Then the disk 2 rotates, and the clamping table 1 enters the second bending assembly 4. The second bending assembly 4 bends the fixing strips 300 on the remaining pair of frames 100 to complete the mutual connection between each frame 100 and the brush box 200 to form a brush holder. The disk 2 rotates, and the brush holder is moved to below the blanking assembly 5, and the blanking assembly 5 transfers the brush holder out of the clamping table 1.

[0044] Embodiment 2:

[0045] As Figures 3 to 4 shown in Figures 3 to 4 , in this embodiment, in addition to including the structural features of the foregoing embodiment, the transfer device 33 and the blanking assembly 5 both include a cross beam 51, a sliding frame 52, a lifting cylinder 53, a sliding actuator 54 and a clamping jaw 55. The cross beam 51 extends along the radial direction of the disk 2. The sliding frame 52 is driven by the sliding actuator 54 and is slidably mounted on the cross beam 51. The lifting cylinder 53 is mounted on the sliding frame 52, and the clamping jaw 55 is mounted at the outer end of its piston rod.

[0046] Further, the sliding actuator 54 includes a pair of pulleys 541 rotatably mounted at both ends of the top of the cross beam 51. A transmission belt 542 is installed between the pair of pulleys 541. One of the pulleys 541 is connected to a motor, and the transmission belt 542 is fixedly connected to the sliding frame 52.

[0047] In this embodiment of the present application, due to the adoption of the above structure, when it is necessary to transfer the frame 100 or the brush box 200, the motor drives the pulley 541 to rotate, and the transmission belt 542 drives the sliding frame 52, the lifting cylinder 53 and the clamping jaw 55 to slide on the cross beam 51. The lifting cylinder 53 acts to lift and lower the clamping jaw 55. After the clamping jaw 55 clamps the frame 100 or the brush box 200, the lifting cylinder 53 controls the clamping jaw 55 to rise. After the clamping jaw 55 is transferred outside the corresponding clamping frame 6 or the clamping table 1, the lifting cylinder 53 acts and the outer end of its piston rod descends, driving the clamping jaw 55 to descend, placing the frame 100 in the clamping frame 6 or lowering the height of the brush holder, and then releasing the frame 100 or the brush holder, so that the frame 100 is transferred into the clamping frame 6 or the brush holder is unloaded.

[0048] Embodiment 3:

[0049] As Figures 1 to 2 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, the clamping frame 6 includes a hollow frame body 61 and a pair of side plates 62 extending towards the center of the clamping table 1. The height of the side plates 62 is lower than that of the hollow frame body 61.

[0050] Further, it further includes a pair of cylinders three 7 disposed outside each bending assembly 4. The outer ends of the pistons of each cylinder three 7 are fixedly provided with insertion rods 8, and each insertion rod 8 can extend into the hollow frame body 61 at the corresponding position.

[0051] Further, it further includes a pair of cylinders four 9. The outer ends of the pistons of each cylinder four 9 are fixedly provided with trays 10, and each tray 10 enters and exits the bottom of the clamping table 1 of the corresponding bending assembly 4 under the drive of the corresponding cylinder four 9.

[0052] In this embodiment of the present application, due to the adoption of the above structure, the frame 100 is placed between a pair of side plates 62, the brush box 200 is erected on the top surfaces of the side plates 62, and abuts against the inner ends of the hollow frame bodies 61 all around. When the placement of each frame 100 and the brush box 200 is completed and before bending, both the cylinder three 7 and the cylinder four 9 act. The insertion rod 8 is inserted into the outer hollow frame body 61, and the tray 10 extends into the bottom surface of the clamping table 1 and abuts against the bottom surface of the clamping table 1 to position and fix the clamping table 1, ensuring that when the bending assembly 4 performs the bending action, the fixing strips 300 on each frame 100 are in the correct position. After the bending of each fixing strip 300 is completed, the pistons of the cylinder three 7 and the cylinder four 9 retract, and the insertion rod 8 and the tray 10 move away from the clamping table 1.

[0053] Embodiment 4:

[0054] As shown Figures 6 to 7 In this embodiment, in addition to including the structural features of the foregoing embodiment, the bending assembly 4 includes a frame body 41. A bending cylinder is installed on the top of the frame body 41. The lower end of the piston of the bending cylinder is fixedly provided with a lifting plate 42. A floating plate 44 is installed at the bottom of the lifting plate 42 through an elastic element 43. A dovetail groove 45 is provided at the bottom of the floating plate 44. A pair of sliding blocks 46 are slidably installed at both ends of the dovetail groove 45. A triangular block 47 is provided at the top end of each sliding block 46. A pair of pushing blocks 48 are provided at the bottom of the lifting plate 42. Each pushing block 48 is used to push a pair of pushing blocks 48 to approach each other when the lifting plate 42 and the floating plate 44 approach each other.

[0055] In this embodiment of the present application, due to the adoption of the above structure, the piston of the bending cylinder extends, causing the lifting plate 42 and the floating plate 44 to descend. The bottom surface of the floating plate 44 first contacts the top of the corresponding hollow frame bodies 61. At the same time, the fixing plates on a corresponding set of frames 100 enter the dovetail groove 45 and between a pair of sliding blocks 46. Then the lifting plate 42 continues to descend, approaching the floating plate 44. The elastic element 43 is compressed and shortened. Each pushing block 48 descends at the same time, pushing a pair of sliding blocks to approach each other, pushing and bending a pair of fixing plates, so that one side of the pair of fixing plates abuts against the outer surface of the brush box 200. Then the piston of the bending cylinder retracts. While the lifting plate 42 and the floating plate 44 rise, the elastic element 43 releases elastic potential energy, causing the lifting plate 42 and the floating plate 44 to separate. The lower ends of the pushing blocks 48 and the inclined surfaces of the triangular blocks 47 are in transmission cooperation through a T-shaped groove and a T-shaped block. At this time, the pushing blocks 48 rise relative to the sliding blocks, and the pair of sliding blocks separate from each other;

[0056] The elastic element 43 is a spring 431, a sliding rod 432 and a fixing sleeve 433. The fixing sleeve 433 is fixedly connected to the lifting plate 42. The lower end of the sliding rod 432 is fixedly provided on the top surface of the floating plate 44. The upper end passes through the fixing sleeve 433 and is provided with a limit ring 434. The spring 431 is sleeved outside the sliding rod 432, and the upper and lower ends respectively abut against the lower end of the fixing sleeve 433 and the top surface of the floating plate 44.

[0059] S1. The feeding assembly 3 transfers the frame 100 to the frame clamp 6;

[0060] S2. The disk 2 rotates, and the clamping table 1 with the frame 100 moves out of the feeding assembly 3;

[0062] S4. The disk 2 rotates, and the clamping table 1 with the frame 100 and the brush box 200 moves to the corresponding position of the bending assembly 4;

[0063] S5. The bending component 4 bends the fixing bars 300 on each frame 100 to fix the frame 100 and the brush box 200, obtaining a brush holder;

[0064] S6. The disk 2 rotates, and the clamping table 1 with the brush holder moves to the corresponding position of the blanking component 5;

[0065] S7. The blanking component 5 operates to blank the brush holder.

[0066] In this embodiment of the present application, due to the adoption of the above method, in the whole process, the worker only needs to add the frame 100 to the feeding component 3 and be responsible for placing the brush box 200, which reduces the labor intensity of the worker, improves the work efficiency and the assembly accuracy of the brush box 200.
