[0023] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings. Example

[0024] Cooperate Figures 1 to 8 As shown, this utility model discloses an automatic drilling device for carbon fiber frame 10, which realizes automatic feeding, drilling and unloading of carbon fiber frame 10, effectively improving efficiency and reducing labor costs. At the same time, the mechanized operation realizes the standardization of products and effectively guarantees product quality.

[0025] Cooperate Figures 1 to 8 As shown, an automatic drilling device for a carbon fiber frame 10 includes a transfer robot 20, a feeding device 30, a positioning device 40, a drilling device 50, and a unloading device 60 arranged sequentially along the periphery of the transfer robot 20. The feeding device 30 includes a rotating platform 31, and the rotating platform 31 is provided with a plurality of placement units 32 for placing the vehicle frame 10 along the circumferential direction; The positioning device 40 includes a positioning platform 41 and at least two sets of positioning components 42 disposed on the positioning platform 41, and the vehicle frame 10 is positioned by the positioning components 42. The drilling device 50 includes a transverse module 51 and a lifting module 52. The transverse module 51 is provided with two fixing units 511 of the fixed frame 10, which are arranged horizontally. The lifting module 52 is located above the transverse module 51 and is provided with a drill bit 521. The lifting module 52 drives the drill bit 521 to move up and down reciprocally. The transfer robot 20 transfers the frame 10 of the loading device 30 to the positioning device 40 for positioning, transfers the positioned frame 10 to the drilling device 50 for drilling, and transfers the drilled frame 10 to the unloading device 60 for collection and placement.

[0026] The worker places the vehicle frame 10 to be processed into the loading device 30. The transfer robot 20 transfers the vehicle frame 10 from the loading device 30 to the positioning device 40. The positioning device 40 precisely positions the vehicle frame 10, facilitating accurate gripping and placement by the subsequent transfer robot 20, ensuring the accuracy of subsequent drilling. The transfer robot 20 transfers the positioned vehicle frame 10 to the drilling device 50, which drills holes in the vehicle frame 10. After drilling, the transfer robot 20 transfers the vehicle frame 10 to the unloading device 60 for unloading. The unloading device 60 collects and places the vehicle frames 10. When a certain number of vehicle frames 10 have been collected, the worker unloads the vehicle frames 10, which then proceed to the next processing step.

[0027] Cooperate Figures 2 to 3 As shown, the feeding device 30 is equipped with a rotating platform 31, and multiple placement units 32 are set on the rotating platform 31. This ensures that the worker's placement of the frame 10 and the robot's gripping of the frame 10 do not interfere with each other, thereby improving production efficiency.

[0028] The placement unit 32 includes multiple limiting posts perpendicular to the rotating platform 31. The vehicle frame 10 is embedded between the limiting posts and fixed in place. The placement unit 32 can stack multiple vehicle frames 10. Specifically, the vehicle frame 10 is roughly T-shaped. One placement unit 32 has five limiting posts, three of which form a first limiting group 321 for limiting the middle of the vehicle frame 10, and the remaining two form a second limiting group 322 for limiting one end of the vehicle frame 10, thus achieving the limiting and fixing of the vehicle frame 10. In addition, the vehicle frame 10 is placed in a limited position by the aforementioned limiting posts, and multiple vehicle frames 10 can be stacked in one placement unit 32, effectively increasing the number of vehicle frames 10 that the loading device 30 can hold simultaneously.

[0029] The vehicle frame 10 has two opposite placement orientations on the rotating platform 31 (the middle portion of the vehicle frame 10 is located in the middle or at the edge of the rotating platform 31, respectively). The placement unit 32 adjusts the position of the limiting posts according to the different placement orientations of the vehicle frame 10. One configuration of the placement unit 32 is that the first limiting group 321 is located in the middle of the rotating platform 31 and the second limiting group 322 is located at the edge of the rotating platform 31; another configuration is that the positions of the first limiting group 321 and the second limiting group 322 are exchanged. Furthermore, the number of placement units 32 is set to an even number, and the two placement orientations of the vehicle frame 10 are spaced apart along the circumference of the rotating platform 31. The two placement orientations of the vehicle frame 10 facilitate subsequent entry of the transfer robot 20 into the positioning device 40, drilling device 50, and unloading device 60 in different directions after the robot grasps the vehicle frame 10. In this embodiment, the number of placement units 32 is four.

[0030] In this embodiment, the rotating platform 31 is provided with weight reduction holes 311. The frame 10 is generally T-shaped, and it occupies little space after being placed on the rotating platform 31. For some rotating platforms 31 that do not need to support the frame 10, the weight reduction holes 311 are designed to reduce the weight of the rotating platform 31, thereby saving energy and reducing emissions.

[0031] Cooperate Figures 4 to 5 As shown, the positioning component 42 includes a positioning block 421 and a positioning cylinder 422 disposed on one side of the positioning block 421. The end of the frame 10 is placed between the positioning block 421 and the positioning cylinder 422. The piston of the positioning cylinder 422 pushes against the frame 10 to make it fit tightly against the positioning block 421 for positioning. Specifically, a frame 10 is positioned by two sets of positioning components 42. The two longer ends of the frame 10 are respectively placed in the two sets of positioning components 42. The two sets of positioning components 42 work simultaneously to achieve precise positioning of the frame 10.

[0032] In this embodiment, there are three sets of positioning components 42, and the three sets of positioning components 42 are arranged in an isosceles triangle shape. The three sets of positioning components 42 can be used for positioning the frame 10 in two opposite directions, corresponding to the two placement directions of the frame 10 in the feeding device 30, and one set of positioning components 42 is reused, making the overall structure simpler and more compact.

[0033] The positioning platform 41 is provided with a clearance hole 411 to facilitate the transfer robot 20 to grasp the frame 10. The clearance hole 411 is located below the part of the frame 10 that is grasped by the transfer robot 20, so as to facilitate the transfer robot 20 to make room when grasping the frame 10.

[0034] Cooperate Figure 1 , Figure 6As shown, the lateral movement module 51 has two fixed units 511, which are used to fix the vehicle frame 10 in two directions respectively. The lateral movement module 51 drives the two fixed units 511 to move laterally back and forth. When one of the fixed units 511 moves under the drill bit 521, the drill bit 521 drills a hole in the vehicle frame 10 in the fixed unit 511. The other fixed unit 511 is loaded and unloaded by the transfer robot 20. Setting up two fixed units 511 can improve efficiency.

[0035] Specifically, the fixing unit 511 includes a fixing groove 512 and at least two sets of fixing components. Each fixing component includes a fixing block 513 and a fixing drive member 514 that drives the fixing block 513 to rise, fall, and rotate. The fixing groove 512 is adapted to the size of the frame 10, with part of the frame 10 embedded within it. The fixing block 513 of the fixing component then presses the frame 10 downwards. Furthermore, the two fixing grooves 512 are oriented in opposite directions, corresponding to the opposite orientation of the placed frame 10, which corresponds to the two orientations of the frame 10 placed in the front-end feeding device 30 and the positioning device 40, respectively.

[0036] The fixing drive component 514 is a telescopic rotary cylinder. One end of the fixing block 513 is connected to the piston rod of the telescopic rotary cylinder, and the other end is pressed against the surface of the frame 10. When the fixing unit 511 loads or unloads materials, the telescopic rotary cylinder drives the fixing block 513 to rise and rotate to the outside of the fixing groove 512 to facilitate loading and unloading by the transfer robot 20. When drilling, the telescopic rotary cylinder drives the fixing block 513 to rotate to the fixing groove 512 and presses it downward against the surface of the frame 10, thereby fixing the frame 10.

[0037] Cooperate Figure 1 , Figure 7 As shown, the unloading device 60 includes a frame, which includes multiple horizontally parallel crossbars 61. One end of the vehicle frame 10 is embedded between adjacent crossbars 61 to collect and place the vehicle frame 10. With one end of the vehicle frame 10 embedded between adjacent crossbars 61, the other two ends automatically fall down and rest on the crossbars 61, thus collecting and placing the vehicle frame 10. The structure is simple in design and easy to operate.

[0038] Cooperate Figure 1 , Figure 8 As shown, the transfer robot 20 includes a suction cup assembly 21 and a clamping assembly 22. The suction cup assembly 21 transfers the frame 10 from the loading device 30 to the positioning device 40 for positioning, and transfers the drilled frame 10 to the unloading device 60 for collection and placement. The clamping assembly 22 transfers the positioned frame 10 to the drilling device 50. The suction cup assembly 21 adheres to the surface of the frame 10 to hold and transfer the frame 10, while the clamping assembly 22 clamps both sides of one end of the frame 10 for transfer.

[0039] The working process of the automatic drilling equipment for the carbon fiber frame 10 is as follows: the feeding device 30 has four placement units 32, two of which are adjacent to the transfer robot 20 and are picked up and fed by it, while the other two placement units 32 are stacked and fed by workers. When drilling a hole in the frame 10 of one of the fixed units 511 of the drilling device 50, the transfer robot 20 picks up the frame 10 to be processed from the loading device 30 and transfers it to the positioning device 40. After the positioning device 40 completes the positioning, the transfer robot 20 clamps and transfers the positioned frame 10 to another fixed unit 511 for fixing. After the frame 10 in the fixed unit 511 is drilled, the lateral movement module 51 laterally moves the frame 10 of the other fixed unit 511 to below the drill bit 521 for drilling. At the same time, the transfer robot 20 transfers the drilled frame 10 to the unloading device 60 for collection and placement, and then transfers a new frame 10 to be drilled from the loading device 30, and so on. The frame 10 has two placement directions in the loading device 30. When the transfer robot 20 picks up the frame 10 to be processed, it picks up the frame 10 placed in the two directions alternately. The corresponding positioning components 42 and fixing units 511 at the rear also work alternately.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
