[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "horizontal," "vertical," "top," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example

[0025] like Figure 1-8 As shown, the screw gripping assembly for the brake fixing bracket in this embodiment includes a vibratory feeder 1, a reversing track 2, a storage channel 3, a material distribution assembly 4, and a gripping assembly 5 arranged sequentially along the screw conveying direction. The vibratory feeder 1 is provided with a spiral track 11 that causes the screws to rise. The spiral track 11 is provided with an inclined surface 12 facing the side wall. The outlet of the spiral track 11 coincides with the inlet of the reversing track 2. The reversing track 2 includes a ramp surface 21 and a blocking surface 22. The inlet ramp of the ramp surface 21 is inclined downward, and the outlet ramp of the ramp surface 21 is vertically downward. The ramp surface 21 is smoothly transitioned from its inlet to its outlet. The inlet of the blocking surface 22 is vertically arranged, and the outlet of the blocking surface 22 is horizontally arranged. The blocking surface 22 is smoothly transitioned from its inlet to its outlet. The gap 23 between the ramp surface 21 and the blocking surface 22 is larger than the diameter of the screw shank and smaller than the diameter of the screw head.

[0026] With this design, the screw lies on the spiral track 11 and rises close to the side wall under the drive of the vibratory plate 1. When the screw enters the reversing track 2, the screw rod hangs down from the gap 23. The head of the screw is supported by the ramp surface 21 and the blocking surface 22. As the screw moves forward, it changes from a horizontal state to a vertical state.

[0027] According to one embodiment of the present invention, the storage channel 3 includes a support platform 31 and a limiting plate 32 disposed above the support platform 31. The support platform 31 is provided with a through groove 33 for the screw rod to pass through. The screw head is abutted against the support platform 31. The limiting plate 32 is clearance-fitted with the upper surface of the screw head.

[0028] This design prevents the screws from falling off the support platform 31 when they move.

[0029] According to one embodiment of the present invention, the material dispensing component 4 includes a base 41 and a fixing plate 42 disposed above the base 41 and fixedly connected to the base 41. The fixing plate 42 has a limiting groove 421, and a material dispensing turntable 43 is rotatably disposed in the limiting groove 421. The material dispensing turntable 43 is provided with receiving grooves 431 that correspond one-to-one with the screw holes of the brake fixing bracket 6. The receiving grooves 431 cooperate with the inner wall of the limiting groove 421 to limit the screws therein. A reversing component for driving the material dispensing turntable 43 to change direction is provided between the material dispensing turntable 43 and the base 41. The fixing plate 42 is provided with a through groove 44, which is connected between the limiting groove 421 and the through groove 33.

[0030] With this design, the receiving groove 431 on the material distribution turntable 43 corresponds one-to-one with the screw holes of the brake fixing bracket 6. The gripping component only needs to grip the screw from the receiving groove 431 once to achieve one-time assembly of the brake fixing bracket 6.

[0031] According to one embodiment of the present invention, the reversing assembly includes a stepper motor 45 fixedly connected to the base 41, and the output shaft of the stepper motor 45 is connected to the material distribution turntable 43.

[0032] According to one embodiment of the present invention, the gripping component 5 includes a robotic arm 51 and a gripping device disposed on the robotic arm 51. The gripping device includes grippers 52 corresponding one-to-one with the receiving groove 431 and a first driving component for driving the grippers 52 to open and close.

[0033] According to one embodiment of the present invention, the first driving component includes a pneumatic finger 53, and the gripper 52 is fixedly connected to the slide rod of the pneumatic finger 53.

[0034] According to one embodiment of the present invention, the gripping device includes a connecting seat 54 fixedly connected to the robotic arm 51, a mounting plate 55 disposed on the connecting seat 54, and the pneumatic finger 53 fixedly connected to the mounting plate 55.

[0035] According to one embodiment of the present invention, the mounting plate 55 and the connecting seat 54 are vertically engaged, and a slider 541 and a groove 551 are provided between the mounting plate 55 and the connecting seat for sliding engagement; a second driving component for driving the mounting plate 55 to move up and down is provided between the mounting plate 55 and the connecting seat 54.

[0036] With this design, when the screw is installed into the brake mounting bracket, the mounting plate 55 can be driven down first, so that the shank of the screw can be initially inserted into the screw hole of the brake mounting bracket, ensuring the installation accuracy.

[0037] According to one embodiment of the present invention, the second drive assembly includes a lifting cylinder 56, the cylinder body of the lifting cylinder 56 is fixedly connected to the connecting seat 54, and the piston rod of the lifting cylinder 56 is fixedly connected to the mounting plate 55.

[0038] According to one embodiment of the present invention, the gripper 52 is provided with an arc-shaped groove 521 that limits and cooperates with the screw.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
