Description

Technical Field

[0001] This utility model relates to a variable pitch mechanism, and more particularly to a flipping variable pitch mechanism. Background Technology

[0002] As people's demands for electronic products increase, metal frames are commonly used to enhance their strength and texture. To further improve the appearance and design, surface treatments are often applied to these frames, with anodizing being a common method for aluminum frames. To improve surface treatment efficiency, multiple frames need to be processed simultaneously. However, due to inconsistencies in the layout of the surface treatment fixtures and trays, the required spacing and orientation of the frames differ during loading. Therefore, it's impossible to directly transfer frames from the tray to the surface treatment fixture or vice versa. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example: A pitch-changing mechanism includes a machine base 1, a pitch-changing assembly 2 mounted on the machine base 1, and a tilting assembly 3 mounted on the machine base 1. The pitch-changing assembly 2 includes a pitch-changing slide 20, pitch-changing sliders 27 slidably engaged with the top of the pitch-changing slide 20, and a pitch-changing pusher 26 mounted on the pitch-changing slide 20. The pitch-changing sliders 27 are linearly arranged along the sliding direction. A workpiece positioning surface 25 is provided on the top of each pitch-changing slider 27. An elastic clamp 22 is provided at one end of the workpiece positioning surface 25. A connecting rod 23 connects adjacent pitch-changing sliders 27, and one end of the connecting rod 23 is fixed to one of the pitch-changing sliders 27. The connecting rod 23 is slidably connected to another variable pitch slider 27 at one end. The connecting rod 23 and the variable pitch slider 27 are provided with a stop head 24 at the sliding end. That is, when the variable pitch slider 27 slides to the end of the connecting rod 23, the variable pitch slider 27 moves with the connecting rod 23. The variable pitch pusher 26 is connected to the variable pitch slider 27 arranged at the end. The flipping assembly 3 includes a flipping frame 30, a flipping arm 32 that rotates horizontally with the flipping frame 30, and a flipping gripper assembly 34 disposed on the flipping arm 32. The flipping frame 30 is provided with a flipping motor 33 for driving the flipping arm 32 to rotate.

[0025] The aforementioned method involves using the flipping component 3 to transport the electronic product frame onto the pitch-changing component 2, achieving flipping during transport. The pitch-changing sliders 27 on the pitch-changing component 2 move sequentially, separating the electronic product frame at equal intervals. This facilitates the transfer and matching of the electronic product frame between the surface treatment fixture and the material tray, enabling automated loading and unloading of the surface treatment fixture in conjunction with a robotic arm. The connecting rod 23 transmits power to the pitch-changing sliders 27 and limits their spacing.

[0026] The variable pitch slide 20 is equipped with two parallel variable pitch pushers 26, which are respectively connected to both ends of the arranged variable pitch sliders 27. Variable pitch limiting buffers 21 are provided at both ends of the variable pitch slide 20. By using the two variable pitch pushers 26 to pull the variable pitch sliders 27 in opposite directions from both ends, the cumulative error is effectively reduced, and the pitch change is more precise. The variable pitch limiting buffers 21 can be spring buffers.

[0027] To improve execution efficiency, the variable pitch actuator is a cylinder.

[0028] To facilitate quick clamping of the electronic product frame on the variable pitch slider 27, the elastic clamp 22 includes an unlocking cylinder 220 disposed at the bottom of the variable pitch slide table 20, an unlocking plate 223 disposed on the unlocking cylinder 220, a clamping slide rod 226 slidably engaged with the variable pitch slider 27, a clamping head 222 disposed at one end of the clamping slide rod 226, a traction head 224 disposed at the other end of the clamping slide rod 226, and a clamping elastic element 221 connecting the clamping slide rod 226 and the variable pitch slider 27. The clamping elastic element 221 applies a spring force to the clamping slide rod 226 toward the workpiece positioning surface 25. The unlocking plate 223 is provided with a clearance hole 225 to facilitate the passage of the clamping slide rod 226. The clearance hole 225 is a strip-shaped hole that extends along the sliding direction of the variable pitch slider 27. The width of the clearance hole 225 is smaller than the vertical width of the traction head 224. A clamping elastic element 221 is used to push and clamp, preventing damage to the frame of the electronic product. The clamping elastic element 221 can be a spring fitted onto the clamping slide bar 226.

[0029] To compensate for the discrepancy between the number of electronic products transferred on the surface treatment fixture and the number transferred on the tray, a material distribution component 4 is also included. The material distribution component 4 includes a material distribution platform 40, a material distribution chute 41 disposed on the top of the material distribution platform 40, a baffle 42 disposed at the outlet of the material distribution chute 41, a baffle cylinder 43 disposed on the baffle 42, and a pushing module 44 disposed below the material distribution platform 40. The pushing module 44 is provided with a pushing claw 45 that moves along the length of the material distribution chute 41, extending upwards from the top of the material distribution chute 41. The pushing claw 45 pushes an appropriate number of electronic product frames into the flip-grip assembly 34, the number of electronic product frames accommodated in the flip-grip assembly 34 being consistent with the capacity of the variable pitch component 2.

[0030] To facilitate the docking of the material dispensing chute 41 with the flipping gripper assembly 34 during material dispensing, and to allow the flipping gripper assembly 34 to avoid the material dispensing platform 40 during flipping, the material dispensing platform 40 includes a material dispensing stand 400, a material dispensing slide plate 402 that slides horizontally along the material dispensing stand 400, and a push cylinder 401 disposed on the material dispensing stand 400. The push cylinder 401 is connected to the material dispensing slide plate 402, and the sliding direction of the material dispensing slide plate 402 is consistent with the extension direction of the material dispensing chute 41. The material dispensing chute 41 is disposed on the material dispensing slide plate 402.

[0031] To smoothly place the electronic product frame onto the variable-pitch slider 27, the flipping arm 32 is equipped with a flipping avoidance cylinder 31, and the flipping gripper assembly 34 is disposed on the flipping avoidance cylinder 31. The flipping gripper assembly 34 includes a gripper frame 340 and a gripper groove 343 disposed on the gripper frame 340. A clamping positioning block 341 is provided at one end of the gripper groove 343 away from the material distribution groove 41, and a clamping fixing block 342 is provided on one side of the gripper groove 343. A flipping clamping cylinder 346 is provided on the gripper frame 340, and a flipping clamping seat 345 is provided on the flipping clamping cylinder 346. A flipping clamping head 344 corresponding to the workpiece 5 is elastically connected to the flipping clamping seat 345. The output direction of the flipping avoidance cylinder 31 is perpendicular to the flipping axis of the flipping arm 32.

[0032] To ensure that the material distribution chute 41 and the gripper chute 343 are on the same horizontal plane during material distribution and to prevent material spillage, a receiving limit frame 8 is also included. The receiving limit frame 8 is threadedly connected to a receiving stop bolt 7, and the tilting arm 32 is equipped with a receiving stop block 6. When the tilting arm 32 is in the receiving position, the bottom of the receiving stop block 6 abuts against the receiving stop bolt 7. The height of the gripper chute 343 can be finely adjusted using the receiving stop bolt 7.

[0033] During operation, the robotic arm transfers the electronic product frame from the surface treatment fixture into the material distribution chute 41. The flipping gripper assembly 34 flips to a horizontal receiving position, and the pusher 45 pushes the electronic product frame from the material distribution chute 41 into the gripper groove 343 of the flipping gripper assembly 34. The flipping clamping head 344 clamps the electronic product frame in the gripper groove 343, and the flipping gripper assembly 34 flips 180°. The flipping avoidance cylinder 31 drives the flipping gripper assembly 34 to descend, the flipping clamping head 344 releases, and the electronic product frame in the flipping gripper assembly 34 is placed on the variable pitch slider 27. The elastic chuck 22 clamps the electronic product frame on the variable pitch slider 27. Under the push of the variable pitch pusher 26, the variable pitch sliders 27 are pulled apart one by one towards both ends.

[0034] The workpiece 5 mentioned above is the frame of an electronic product.
