DETAILED DESCRIPTION

[0015] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, the embodiment of the present application discloses a bearing laser marking mechanism 7, comprising a frame 1, a table 2 is arranged on the frame 1, a carrier frame 3 is arranged on the table 2, a rotary drive mechanism 4 is installed at the bottom of the table 2, a rotating frame is arranged on the carrier frame 3, a driving shaft of the rotary drive mechanism 4 passes through the table 2 and the carrier frame 3 and is fixedly connected to the bottom of the rotating frame, a feeding transmission line 5 extending into the top of the table 2 is arranged on one side of the table 2, a discharging transmission line 6 extending into the top of the table 2 is arranged on the other side of the table 2, and a laser marking mechanism 7 for marking bearings is arranged on one side of the rotating frame;

[0017] The rotating frame includes a disc 8, and a plurality of notches 801 for accommodating bearings are circumferentially arranged on the side of the disc 8. When one of the laser bearings moves to the bottom of the laser marking mechanism 7, one notch 801 is located above the feed transmission line 5, and one notch 801 is located above the discharge transmission line 6.

[0018] Specifically, the feeding transmission line 5 and the discharging transmission line 6 may be belt transmission lines, and guide blocks may be provided on both sides of the belt transmission lines so that the products can be accurately fed into the notch 801 of the disc 8 .

[0019] During specific operation, the rotary drive structure drives the disc 8 to rotate, and the bearing to be marked is placed on the feed transmission line 5 and transmitted forward, and is sent into the notch 801 on the side of the disc 8. Then, the bearing to be marked is transported to the bottom of the laser marking mechanism 7 under the drive of the disc 8 for marking. After the marking is completed, the rotary drive structure continues to drive the disc 8 to rotate, and performs the marking of the next bearing and the feeding operation of the new bearing. Then, when the marked bearing moves to the discharge transmission line 6, it is transmitted out of the disc 8 under the action of the discharge transmission line 6.

[0020] In this structure, by setting the rotating disc 8, the feeding transmission line 5 and the discharging transmission line 6, during laser marking, the feeding transmission line 5 and the discharging transmission line 6 can simultaneously feed and discharge materials into the rotating disc 8, so that the feeding and discharging operations can be carried out simultaneously, thereby reducing the time of the entire marking process and improving the marking efficiency.

[0021] In this embodiment, a dust extraction pipe 9 for cleaning smoke and dust after marking is arranged below the laser marking mechanism 7 .

[0022] It should be explained that the dust extraction pipe 9 of this structure will be connected to an external dust extraction device.

[0023] Specifically, when the product moves to the bottom of the laser marking mechanism 7, the laser marking mechanism 7 performs a laser marking operation on the product. During the laser marking operation, smoke and dust will be emitted. At this time, the dust extraction pipe 9 will extract the smoke and dust to prevent dust from scattering.

[0024] In this embodiment, a retaining ring 10 is provided on the outer side of the disc 8, and the retaining ring 10 is fixed on the supporting frame 3. The retaining ring 10 is provided with a first opening 101 and a second opening 102. The first opening 101 corresponds to the position of the feed transmission line 5, and the second opening 102 corresponds to the position of the discharge transmission line 6.

[0025] Specifically, during operation, the product is fed into the notch 801 of the disc 8, and then the disc 8 rotates, thereby driving the product in the notch 801 to rotate together. At the same time, due to the blocking effect of the retaining ring 10, the product will not fly out due to the inertia of rotation during the rotation of the disc 8, thereby ensuring the stability of the operation of the equipment.

[0026] In this embodiment, the retaining ring 10 is provided with a first detection sensor 11 and a second detection sensor 12 for detecting the presence or absence of material. The first detection sensor 11 is located between the feed transmission line 5 and the first marking mechanism, and the second detection sensor 12 is located between the feed transmission line 5 and the discharge transmission line 6.

[0027] Specifically, the first detection sensor 11 and the second detection sensor 12 may be photoelectric sensors, distance sensors, etc.

[0028] Specifically, the first detection sensor 11 can be used to detect whether there is a bearing to be marked in the gap 801. If the gap 801 is vacant, the gap will be skipped during the subsequent marking operation. If there is no product at this position after multiple consecutive rounds of detection, it can be determined that the equipment is working abnormally, and an alarm needs to be issued. The second detection sensor 12 is used to detect whether there is still a product after rotating to the work station. If the product is not there, it means that the operation is normal at this time. If the product is still there, it proves that the product is accurately transmitted from the discharge transmission line 6 at this time. At this time, the device issues an alarm, and manually checks whether a material jam occurs to prevent repeated marking caused by material jams.

[0029] The arrangement of the first detection sensor 11 and the second detection sensor 12 can detect whether there is material or material is stuck, etc., to prevent empty marking or repeated marking due to material jamming, etc., thereby improving the yield rate of the product.

[0030] In this embodiment, a third detection sensor 13 for detecting whether there is material is provided on one side of the feeding transmission line 5, and a fourth detection sensor 14 for detecting whether there is material is provided on one side of the discharging transmission line 6.

[0031] Specifically, the third detection sensor 13 and the fourth detection sensor 14 are used to detect whether there are products being transmitted on the feed transmission line 5 and the discharge transmission line 6, so as to determine whether the equipment is in normal operation. For example, after the bearing completes a marking operation, the bearing is transmitted outward from the discharge transmission line 6, and the fourth detection sensor 14 will receive a signal once, otherwise it can be determined that the equipment is abnormal.

[0032] At the same time, the fourth detection sensor 14 can be used to prevent the backlog of materials in the rear section. For example, when the bearings on the unloading transmission line are full, it means that the bearings are no longer transmitting forward. At this time, the fourth detection sensor 14 will receive a long-term signal, and the rotating drive mechanism 4 will drive the disc to pause and the marking will be paused.

[0033] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
