[0036] Embodiment 2

[0037] The structure of the embodiment 2 is basically the same as that of the embodiment 1, and the difference lies in that the feeding device 8 is additionally arranged.

[0038] Referring to Figure 3 and Figure 4 The feeding device 8 is arranged at the feeding position of the transmission belt 2, the workpiece is automatically fed by the feeding device 8, the manual feeding process is reduced, the staff operation is facilitated, and the labor cost is reduced.

[0039] The feeding device 8 includes a feeding box 81 and a driving assembly 82, the feeding box 81 is arranged at the feeding position and located directly above the transmission belt 2, the upper end of the feeding box 81 is opened to facilitate the placement of the workpiece, and the feeding groove 811 is formed in the side wall of the lower end of the feeding box 81, so that the workpiece can pass out of the feeding box 81 through the feeding groove 811 to fall on the transmission belt 2 and be transmitted to the marking position by the transmission belt 2. The driving assembly 82 is installed on the feeding box 81 and used to push the workpiece located at the lowermost position to slide out of the feeding groove 811, so as to realize the automatic feeding.

[0040] In the running process of the laser visual identification marking production line, the driving assembly 82 pushes out the workpiece located at the lowermost position from the feeding groove 811 every interval, so as to realize the feeding process. When the driving assembly 82 is reset, the remaining workpieces fall downward under the action of gravity, so that the workpiece located at the lowermost position corresponds to the position of the feeding groove 811. After a period of time, the driving assembly 82 continues to push the workpiece located at the lowermost position out of the feeding groove 811, so as to realize continuous automatic feeding and reduce labor cost.

[0041] Specifically, the driving assembly 82 comprises a cam 821, a driving piece 822, an elastic piece 823 and a push plate 824. A sliding groove is formed in the side wall of the feeding box 81 and corresponds to the position of the feeding groove 811. The push plate 824 is slidingly arranged in the sliding groove and can slide into the feeding groove 811. When it is necessary to feed the workpiece, the push plate 824 is driven to slide, so that the push plate 824 pushes the workpiece out of the feeding groove 811. After the feeding of the workpiece is completed, the push plate 824 is reset for the next feeding.

[0042] The elastic piece 823 is arranged between the push plate 824 and the feeding box 81. One end of the elastic piece 823 acts on the feeding box 81 and the other end acts on the push plate 824. When the push plate 824 pushes the workpiece out of the feeding groove 811, the elastic piece 823 is in a compressed state. When the elastic piece 823 returns to its original state, the push plate 824 is reset, so as to realize the automatic reset of the push plate 824.

[0043] The driving piece 822 is fixedly installed on the side wall of the feeding box 81. The cam 821 is fixedly installed on the output end of the driving piece 822 and abuts against the push plate 824. Through the rotation of the driving piece 822, the cam 821 is driven to rotate. Through the cooperation of the cam 821 and the elastic piece 823, the push plate 824 is realized to move back and forth, so as to realize repeated automatic feeding. In the embodiment, the driving piece 822 adopts a motor.

[0044] Further, the feeding box 81 is provided with a sleeve 83. The sleeve 83 is arranged at the position of the sliding groove. The push plate 824 is slidingly arranged in the sleeve 83. Through the arrangement of the sleeve 83, the sliding path of the push plate 824 is limited, so as to ensure the sliding stability of the push plate 824. One end of the push plate 824 away from the feeding groove 811 is provided with an abutting plate 825. One end of the elastic piece 823 acts on the sleeve 83 and the other end acts on the abutting plate 825. The cam 821 abuts against the abutting plate 825. The abutting plate 825 is driven to slide by the cam 821, so as to drive the push plate 824 to slide. Through the elastic force of the elastic piece 823, the push plate 824 is realized to move back and forth.

[0045] In the embodiment, the elastic piece 823 adopts a spring. One end of the spring is fixed to the sleeve 83 and the other end is fixed to the abutting plate 825.

[0046] Further, the gap between the bottom wall of the feeding groove 811 and the conveying belt 2 is smaller than the width of the workpiece. By limiting the size of the gap between the bottom wall of the feeding groove 811 and the conveying belt 2, it is ensured that the workpiece will not be turned over during the process of sliding out of the feeding groove 811 and falling on the conveying belt 2, and the front surface of the workpiece is upward, thereby reducing the situation that the machine stops due to the back surface of the workpiece being upward.

[0047] In the embodiment, the feeding groove 811 is located on the side of the feeding box 81 close to the marking station. When the workpiece slides out of the feeding groove 811, the feeding box 81 is driven by the conveying belt 2 to move away from the feeding box 81, thereby further reducing the possibility of the workpiece being turned over and ensuring smooth operation of the machine.

[0048] Embodiment 3

[0049] The embodiment 3 is substantially the same as the structure of the embodiment 2, and the difference is that the adjusting assembly 9 is additionally provided.

[0050] Referring to Figure 5 The feeding box 81 is fixedly installed on the light shield 6 through the connecting frame 84, and the feeding box 81 is suspended by the connecting frame 84, so that there is a gap between the feeding box 81 and the conveying belt 2. The adjusting assembly 9 is provided on the connecting frame 84 and located between the marking machine 3 and the feeding box 81. When the workpiece slides out of the feeding box 81 and falls on the conveying belt 2, the adjusting assembly 9 adjusts the workpiece to adjust the placement angle of the workpiece, so as to ensure the marking quality.

[0051] Specifically, the adjusting assembly 9 includes a mounting plate 93, a telescopic piece 91 and an adjusting plate 92. The mounting plate 93 is fixed on the connecting frame 84, the telescopic piece 91 is fixed on the mounting plate 93 and faces the conveying belt 2, and the adjusting plate 92 is fixedly installed on the output end of the telescopic piece 91. The telescopic piece 91 can drive the adjusting plate 92 to move towards or away from the conveying belt 2 through the telescopic movement.

[0052] When the workpiece falls on the conveying belt 2 from the feeding box 81, the angle of the workpiece may be deflected. At this time, the marking machine 3 needs to adjust the marking angle before marking when the workpiece is directly conveyed to the marking station by the conveying belt 2, and the marking efficiency is relatively low. By providing the adjusting assembly 9, the angle of the workpiece is preliminarily adjusted, which greatly reduces the number of times of adjusting the angle of the marking machine 3 and increases the marking efficiency.

[0053] Specifically, when the conveying belt 2 conveys the workpiece, the telescopic member 91 drives the adjusting plate 92 to move downward, so that the gap between the adjusting plate 92 and the conveying belt 2 is smaller than the thickness of the workpiece. The conveying belt 2 continuously drives the workpiece to move, and the movement of the workpiece is limited by the adjusting plate 92, so that the workpiece is completely attached to the adjusting plate 92, thereby realizing the adjustment of the angle of the workpiece and ensuring the angle of the workpiece when the workpiece moves to the marking station. When the angle adjustment of the workpiece is completed, the telescopic member 91 drives the adjusting plate 92 to reset, so that the adjusting plate 92 releases the limitation on the workpiece, and the conveying belt 2 continuously drives the workpiece to move, so that the workpiece moves to the marking station for marking.

[0054] In the embodiment, the telescopic member 91 is an electric telescopic rod, and in other embodiments, the telescopic member 91 can be a telescopic cylinder or other structures capable of automatic telescoping.

[0055] The embodiments of the specific implementation are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are indicated by the same reference numerals. Therefore, equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
