DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0039] As shown in the figure, an online automatic positioning device for a laser sanding machine comprises a base 1 and a crossbeam 14, which are the conventional settings of the laser sanding machine in the prior art, wherein the crossbeam 14 is above the base frame and can move back and forth, and the laser source moving in the left-right direction and the up-down direction is installed on the crossbeam 14, so that the laser source can move in six directions of up, down, left, right, front and back according to the process requirements, thereby realizing the laser sanding work. The structure and principle of the laser sanding belong to the conventional settings in the prior art, which will not be described in detail here.

[0040] The laser sanding machine further comprises at least two support frames 2 arranged at intervals and used for supporting the glass, and a positioning block 3 is installed on one of the support frames 2 on the outer side and the end position of all the support frames 2, which can limit the glass in the first direction and the second direction in the horizontal direction. In this example, the number of support frames 2 is five, and the five support frames 2 are arranged at intervals, which are mainly used for placing the glass on the support frames 2 to make the glass work in the static state. In this example, the positioning block 3 is divided into two types. One type of positioning block 3 is installed on the outermost support frame 2 to contact the leftmost surface of the glass, thereby realizing the left-right positioning of the glass. The other type of positioning block 3 is located at the end of the support frame 2 to contact the front end surface of the glass, thereby realizing the front-back positioning of the glass. In order to improve the positioning accuracy, the first direction and the second direction are perpendicular to each other in this example.

[0041] The laser sanding machine further comprises a conveying mechanism, which is installed on the base 1 in a liftable manner and is arranged to convey the glass. The conveying mechanism comprises a plurality of second cylinders 13 arranged at one end position of the conveying mechanism. The extension rods of the second cylinders 13 can limit the horizontal conveying direction of the glass when they are extended. In this example, there are eight second cylinders 13 arranged in the left-right direction of the base 1, which are used to adjust the direction of the glass by the second cylinders 13, so that the front end surface of the glass can contact the outer wall of the extension rod of the second cylinder 13, thereby more quickly and conveniently positioning the glass by the subsequent third cylinder 15, fourth cylinder 16 and fifth cylinder 17, improving the positioning accuracy and positioning efficiency.

[0042] Specifically, the conveying mechanism further comprises:

[0043] The lifting frame 10 is a frame structure, and there are at least two of them. The lifting frame 10 and the support frame 2 on the surface of the base 1 are horizontally spaced and staggered. In this case, there are four lifting frames 10, which are made of aluminum alloy profiles. The lifting frame 10 is installed on the side of the lifting frame 10 and near the tail end of the conveying belt 11. The second air cylinder 13 is installed on the support 12, and the second air cylinder 13 is extended upward. When the telescopic rod is extended upward, the upper end of the telescopic rod is higher than the upper surface of the conveying belt 11.

[0044] The connecting frame 5 is connected between two adjacent lifting frames 10, and is arranged to assemble the plurality of lifting frames 10 into a whole structure. The connecting frame 5 and the lifting frame 10 are connected by bolts.

[0045] The first air cylinder 4 is installed on the base 1, and the first air cylinder 4 is connected to the connecting frame 5. In this case, there are four first air cylinders 4, which are distributed at the four corners below all the lifting frames 10. The first air cylinder 4 mainly supports and drives the lifting frame 10 to move up and down.

[0046] The conveying wheel 9 is rotatably installed at the four corners of the lifting frame 10. The conveying wheel 9 is a synchronous pulley.

[0047] The conveying belt 11 is wound around the conveying wheel 9 of the lifting frame 10. The conveying belt 11 is a synchronous belt, which has the advantage of high conveying accuracy.

[0048] The conveying shaft 8 is synchronously connected to one of the conveying wheels 9 of all the lifting frames 10. In this case, there are four lifting frames 10, and each lifting frame 10 has a conveying wheel 9 at each corner. The conveying shaft 8 is connected to the conveying wheel 9 at the lower end. When the conveying shaft 8 rotates, the four conveying wheels 9 rotate simultaneously, thereby driving the conveying belt 11 to convey the glass.

[0049] The power source is connected to the conveying shaft 8 to drive the conveying wheel 9 to rotate, thereby driving the conveying belt 11 to move. In this case, the power source includes a speed reducer 7 installed on the outermost lifting frame 10 and connected to the conveying shaft 8. The speed reducer 7 is installed with a conveying motor 6.

[0050] When the first air cylinder 4 drives the lifting frame 10 to rise to the upper limit position, the upper surface of the conveying belt 11 is higher than the upper surface of the support frame 2. When the first air cylinder 4 drives the lifting frame 10 to descend to the lower limit position, the upper surface of the conveying belt 11 is lower than the upper surface of the support frame 2. That is, during the conveying of the glass, the lifting frame 10 is in a high position, and the conveying belt 11 can drive the glass to convey forward. When the glass is in contact with the telescopic rod of the second air cylinder 13, the first air cylinder 4 drives the lifting frame 10 to descend, so that the glass falls on the surface of the support frame 2. At this time, the conveying belt 11 and the glass are not in contact with each other.

[0051] Specifically, a third cylinder 15 is mounted on the cross beam 14, which is arranged to push the glass. After the glass falls on the support frame 2, the third cylinder 15 is activated to horizontally push the glass to the position of the positioning block 3 on the outermost support frame 2, which is a row of positioning blocks 3 mounted on the outermost support frame 2 for positioning the glass in the left-right direction.

[0052] Specifically, a fourth cylinder 16 is mounted at the tail of the base 1, the telescopic rod of the fourth cylinder 16 is horizontally arranged, the telescopic rod of the fourth cylinder 16 is connected with a fifth cylinder 17, the telescopic rod of the fifth cylinder 17 is vertically arranged, and the telescopic rod of the fifth cylinder 17 is connected with a push block 18. When the telescopic rod of the fifth cylinder 17 moves downward, the fourth cylinder 16 works to drive the push block 18 to push the glass horizontally, at this time, the horizontal movement direction of the glass is consistent with the conveying direction of the conveying belt, and finally the front end of the glass contacts the positioning block 3 at the end of the support frame 2.

[0053] The online automatic positioning device for the laser sanding machine works as follows. First, the glass is conveyed to the machining area by the conveying mechanism. When the glass reaches the specified position, the front end of the glass contacts the telescopic rod of the second cylinder 13. At this time, the first cylinder 4 drives the lifting frame 10 to descend, so that the glass falls on the support frame 2, and the conveying belt 11 stops working.

[0054] Subsequently, the third cylinder 15 is activated to horizontally push the glass to the positioning block 3 on the outermost support frame 2, so as to realize the positioning of the glass in the left-right direction. Then, the fourth cylinder 16 and the fifth cylinder 17 work cooperatively. The telescopic rod of the fifth cylinder 17 moves downward, and the telescopic rod of the fourth cylinder 16 moves horizontally, so that the push block 18 contacts the glass and pushes the glass to move forward, so that the front end of the glass contacts the positioning block 3 at the end of the support frame 2, and the positioning of the glass in the front-back direction is completed.

[0055] All the cylinders can be controlled by a PLC controller, and the control principle is a conventional means in the prior art, which will not be described in detail here.

[0056] After the positioning is completed, the laser source on the cross beam 14 moves in six directions (up-down, left-right, front-back) according to the preset path, so as to accurately sand the surface of the glass. During the whole process, the cooperative work of the positioning block 3, the cylinders and the conveying mechanism ensures the accurate positioning of the glass, and improves the machining precision and efficiency.

[0057] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
