[0036] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with a specific embodiment.

[0037] See also Figure 1 and Figure 2 The present invention discloses a plug rotary marking machine, including a frame 1, a feeding device 3, a support platform 4, a feeding device 5 and a dividing table 2 are arranged on the upper part of the frame 1, and the dividing table 2 is arranged in the middle position of the upper end of the frame 1. The feeding device 3 and the feeding device 5 are symmetrically distributed on both sides of the dividing table 2, and the support platform 4 is close to the dividing table 2; the dividing table 2 is a rotatable disc-shaped structure, and the material can be fed once every rotation of a certain angle. A material trough 21 is arranged on the dividing table 2, and the material trough 21 is a rectangular through-hole structure, and the through-hole is a structure of upper wide and lower narrow type. There are 4 through-holes and they are symmetrically distributed on the dividing table, and the upper end of the through-hole is the same size as the product 6, and the lower end of the dividing table 2 is the same size as the product 6. A motor 11 is provided in the part, which controls the movement of the indexing table 2, drives the product 6 to pass through the supporting table 4, and then completes the laser marking after passing through the unloading device 5. The loading device 3 is an iron frame structure, and a card slot (not shown) for placing the product is provided on the loading device 3. The card slot and the material trough 21 are on the same horizontal line, and a card plate 22 is provided at both ends of the material trough 21. The front end of the card plate 22 is tangent to the edge of the indexing table 2; the unloading device includes a unloading hopper 51, a dragging cylinder 52 and a toggle cylinder 53. One end of the dragging cylinder 52 is connected and fixed to the unloading hopper 51, and the other end is connected to the toggle cylinder 53; the toggle cylinder 53 is located at the lower end of the material trough 21 of the indexing table 2. The use of a rotary indexing table for product transportation reduces the overall length of the device, thereby reducing the occupied space, and is more stable than conveyor belt transportation. When the card slot and the material slot are set on the same horizontal line, the product can be easily and quickly put into the material slot and then brought to the laser marking point by the rotating indexing table. Secondly, card plates are set on both sides of the material slot. The card plates not only assist the material slot in fixing the product, but also facilitate the operation of other components in the material unloading process. Finally, when unloading, the drag cylinder and the toggle cylinder are used to work together to peel the marked product from the material slot and put it into the unloading hopper.

[0038] In a specific embodiment, the rotation angle of the indexing table is 360 / N degrees, that is, a loading, marking and unloading action is performed every 360 / N degrees of rotation, where N is the number of feeding slots on the indexing plate. The value of N is adjusted according to actual production needs. When N=4, the indexing table rotates 90 degrees to complete a marking action; when N=6, the indexing table rotates 60 degrees to complete a marking action.

[0039] See also Figure 2 and Figure 3The support platform 4 is divided into an upper support platform 42 and a lower support platform 41. The height of the lower support platform 41 is the same as that of the indexing platform 2. The lower support platform 41 is provided with a first laser head 413, a first laser generator 412 and a first hand-cranked focusing module 411. The upper support platform 42 is provided with a second laser head 423, a second laser generator 422 and a second hand-cranked focusing module 421. The components arranged on the upper support platform 42 are the same as those on the lower support platform 41 and the two support platforms are symmetrical in center. The components of the lower support platform 41 are arranged in a positive direction. The components of the support platform 42 are arranged in reverse order; for the lower support platform 41, the first laser head 411 is connected to the first laser generator 412, which is located at the upper end of the dividing table 2 and distributed on the left side of the material trough 21. The first laser generator 412 is arranged on the first hand-cranked focusing module, which includes the first hand-cranked ring 4111 and the first focusing module 411. The first focusing module 411 is provided with a guide rail (not shown) for the movement of the first laser generator 412. The first hand-cranked ring 4111 controls the movement of the first laser generator 412. Among them, the upper support platform 42 is also provided with a positioning and clamping cylinder, which includes a positioning cylinder 44 and a pressure block 45. One end of the positioning cylinder 44 is connected to the upper support platform 42 through a connecting rod 43, and the other end is connected to the pressure block 45. The pressure block 45 is located directly above the material trough 21. Two marking laser ports are provided, and two products can be laser marked at the same time, thereby improving marking efficiency; the marking equipment arranged on the upper and lower support platforms are arranged symmetrically, especially the marking equipment of the upper support platform is arranged in reverse, which can further reduce the occupied space of the entire support platform and fully improve the utilization rate of the space; in addition, a positioning and clamping cylinder is provided, and the positioning cylinder positions the pressing block, so that the pressing block can accurately press the product located in the material trough, ensuring that the product is firmly fixed in the material trough and will not shift during laser marking.

[0040] The working method of the present invention is as follows: placing the product 6 in the loading device 3, adjusting the heights of the lower support table and the indexing table to be consistent, shaking the hand crank ring to focus both laser heads, starting the motor 11, and the product enters the material trough 21 of the indexing disk 2. The indexing disk 2 stops rotating after rotating 90 degrees, and the positioning cylinder 44 on the positioning and clamping cylinder moves, driving the pressing block 45 to move downward, and firmly fixes the product 6 in the material trough 21 and the card plate 22. Then the laser generator generates a laser, and the product 6 is marked by the laser head. After marking, the pressing block 45 rises, and the indexing disk 2 continues to rotate 90 degrees to the unloading device 5, and the dragging cylinder 52 starts to move under the indexing disk 2, and the toggle cylinder 53 is sent into the material trough 21, and then the toggle cylinder moves upward to lift the product 6, and the supporting cylinder 52 is reset, thereby driving the product 6 into the unloading hopper 51.

[0041] The advantages of the present invention are:

[0042] 1) The product is transferred by rotating indexing plate, which reduces the space occupied by the entire device;

[0043] 2) Both the upper and lower support tables are equipped with laser marking devices to improve marking efficiency;
