Detailed Implementation

[0027] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0029] The principle of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0030] This utility model proposes an R-axis laser marking machine, including a rotating drum 1, a rotating drum support 2 for rotatably mounting the rotating drum 1, a rotating drum motor 3 for driving the rotating drum 1 to rotate, a clamp 4 for fixing the marking part 6, and a marking head 5 positioned directly opposite the rotating surface of the rotating drum; the clamp 4 is attracted and fixed to the rotating surface of the rotating drum 1 by an electromagnet 11 disposed on the rotating drum 1. The R-axis laser marking machine has a clamp 4 that is attracted and fixed by an electromagnet 11, which can improve marking efficiency by quickly attaching and detaching the clamp 4.

[0031] In this embodiment, the rotating surface of the rotating drum 1 is evenly provided with four bucket-shaped grooves 12. As the rotating drum 1 rotates, each bucket-shaped groove 12 passes sequentially through the loading position 100 located at the top of the rotating drum 1, the marking position 200 located on one side in the horizontal direction, and the unloading position 300 located at the bottom of the rotating drum 1. The marking head 5 is directly opposite the marking position 200. The bottom of the clamp 4 is provided with a bucket-shaped bottom 41 that fits into the bucket-shaped groove 12, so that the bucket-shaped bottom 41 can be embedded into the bucket-shaped groove 12. The bottom of each bucket-shaped groove 12 is provided with a mounting hole 13, and each mounting hole 13 is provided with an electromagnet 11. The bucket-shaped bottom 41 is provided with an iron sheet for attracting the electromagnet 11. The marking parts 6 can be pre-installed in multiple fixtures 4. Fixtures 4 can be installed on all four sides of the rotating drum 1. As the rotating drum 1 rotates, the fixtures 4 with newly installed marking parts 6 are continuously fed into the loading position 100 at the top of the rotating drum 1. After the fixtures 4 rotate to the marking position 200, the marking head 5 marks the marking parts 6. After the fixtures 4 rotate to the unloading position 300 at the bottom of the rotating drum 1, they are disengaged from the rotating drum 1, thus achieving uninterrupted marking and improving production efficiency. When marking curved marking parts 6, the rotating drum motor 3 drives the rotating drum 1 to rotate synchronously at a small angle during the marking process. After the batch of marking is completed, the rotating drum motor 3 drives the rotating drum 1 to rotate one station.

[0032] When the clamp 4 is fed into the bucket-shaped groove 12 at the loading position 100, the bucket-shaped bottom 41 of the clamp 4 will slide into the bucket-shaped groove 12 under the action of gravity to complete the positioning. Then, the electromagnet 11 is energized to fix the clamp 4. After the marking is completed, when the clamp 4 rotates to the bottom of the rotating drum 1, the electromagnet 11 is de-energized to make the clamp 4 disengage from the rotating drum 1.

[0033] In this embodiment, a feeding conveyor belt 7 is provided below the feeding position 300. The feeding conveyor belt 7 has a perforated array 71 arranged along the movement direction. A bracket 72 and a cylinder 73 for driving the bracket 72 to rise and fall are provided below the feeding conveyor belt 7. A pair of top plates 74 are provided on both sides of the bracket 72. Each top plate 74 has an arc-shaped groove 75 on its top. A pair of support plates 42 are provided on both sides of the clamp 4. Each support plate 42 has an arc surface 43 on its top that matches the shape of the arc-shaped groove 75.

[0034] The bracket 72 is used to support the clamp 4 located at the unloading position 300 after it is raised, and to place the clamp 4 on the unloading conveyor belt 7 when it is lowered. A conveyor belt and a liftable bracket 72 are provided below the rotary drum 1. After the bracket 72 is raised and supports the clamp 4, the electromagnet 11 is de-energized, and then the bracket 72 lowers to place the clamp 4 on the unloading conveyor belt 7, realizing automatic unloading. The top plate 74 of the bracket 72 is connected to the support plate 42 located on the clamp 4 through a groove. The space between the bracket 72 and the clamp 4 is used to accommodate the marking part 6. After the marking part 6 is placed on the unloading conveyor belt 7, the perforations of the marking conveyor belt can also accommodate marking parts 6 whose height exceeds that of the support plate 42.

[0035] In this embodiment, the rotary drum support 2 is mounted on the sliding platform 8, which drives the rotary drum 1 to move axially. The clamp 4 can hold and fix multiple small marking parts 6, or it can hold and fix a single marking part 6. When the size of the marking part 6 exceeds the working range of the marking head 5, the position of the marking part 6 can be moved via the sliding platform 8.

[0036] In this embodiment, the clamp 4 is provided with a clamping plate 44, which is elastically connected to one side plate of the clamp 4. The clamping plate 44 and the other side plate of the clamp 4 cooperate to form a clamping groove 45 for clamping and fixing the marking parts 6. The two ends of the clamping groove 45 are provided with guide plates 46, so that the marking parts 6 can be quickly inserted from the openings at both ends of the clamp 4. In addition, the clamping plate 44 is provided with a scale, which can be used to more accurately control the position of each batch of marking parts 6 inserted into the clamp 4.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
