In this example, the knife handle 712 is in the shape of a thin plate as a whole and has a certain elasticity, so that the knife handle 712 has a certain elasticity during the marking process, and can better fit the outer contour of the glass rod. The knife handle 712 and the inclined lower surface of the inclined knife plate 711 are in contact with each other, and the end of the downwardly inclined side of the knife handle 712 is provided with a blade 1. A plurality of knife handles 712 are provided on the inclined knife plate 711, and there is no mutual interference between different knife handles 712, so that each knife handle 712 can be bent separately to cope with glass rods of various sizes. An acute angle is formed between the knife handle 712 and the second clamping plate 62, that is, the upwardly inclined end of the knife handle 712 faces one side of the second clamping plate 62. Each knife handle 712 is provided with a plurality of blades 1, and the blades 1 are spaced at a set interval, which is related to the scribing requirements on the side of the glass plate; it is convenient to replace the knife handle 712 to replace the blunt blade 1 or replace the blades 1 with different intervals, which is more convenient. The support frame 2 is provided with a guide column 21 that is slidably connected to the inclined blade plate 711, and the guide column 21 passes through the sliding hole provided on the inclined blade plate 711, so that the inclined blade plate 711 can slide up and down along the guide column 21 in cooperation with the cam 724; in this example, two guide columns 21 are provided on the support frame 2, and the two guide columns 21 are respectively provided close to the two support plates. A spring is provided between the bevel blade plate 711 and the support frame 2 as an elastic structure 73; the spring is sleeved on the outer periphery of the guide column 21 to provide an upward elastic force for the bevel blade plate 711, helping the bevel blade plate 711 to resist the cam 724 above, and also enabling the bevel blade plate 711 to move elastically to better absorb the vibration force transmitted by the blade 1 when marking.

[0021] An elastic area (713) is provided at a set distance on the handle (712) near one end thereof where the blade (1) is provided, and the elastic area (713) on the handle (712) can achieve a greater degree of elastic deformation; the elastic area (713) is an area thinner than the thickness of the handle (712), or an area narrower than the width of the handle (712), or a combination of the two, so that the elastic area (713) can produce a greater degree of elastic deformation than other areas of the handle (712), so that the blade (1) on the handle (712) can keep fitting with the glass rod.

[0024] The first motion structure 63 includes a first slide rail 631, a first slider 632, a third power source 633, a first lead screw 634 and a first support plate 635; wherein the first slide rail 631 is fixedly arranged above the support frame 2, and the first slider 632 is slidably arranged on the first slide rail 631; the first support plate 635 is fixedly arranged on the first slider 632, and the first clamping plate 61 is fixedly arranged on the first support plate 635; the first support plate 635 is also connected to the third power source 633 through a lead screw; when the third power rotates, the first support plate 635 is driven by the lead screw. It should be noted that the height of the first clamping plate 61 on the first support plate 635 is higher than the upper surface of the feed plate 32, so that when the first clamping plate 61 moves close to the rolling structure 3, the first clamping plate 61 can extend to the area above the feed plate 32 to push the glass rod through the feed plate 32.

[0025] The feeding structure 4 includes a feeding box 41, an ejector assembly 42 and a tightening plate 43; the feeding box 41 is arranged in the support frame 2, and a discharge port 411 for placing glass rods is arranged on one side of the feeding box 41, and an ejector assembly 42 is arranged on the side of the feeding box 41 opposite to the discharge port 411, and the ejector assembly 42 moves up and down; the bottom of the feeding box 41 is arranged as an inclined surface, and the inclined surface is inclined downward from the side of the discharge port 411 of the feeding box 41 to the side of the ejector assembly 42, so that the glass rods placed in the feeding box 41 can be fed into the feeding box 41 along the feeding box. The bottom of the material box 41 rolls to the position of the ejector assembly 42 in the feeding material box 41; the upper surface of the feeding material box 41 and the support frame 2 are respectively provided with openings corresponding to the ejector assembly 42, and the opening on the support frame 2 is provided close to the feed plate 32 of the rolling structure 3; in this example, the upper surface of the feeding material box 41 is set to be fully open, and the upper surface of the feeding material box 41 is in contact with the lower surface of the square plate 22 at the top of the support frame 2, and the square plate 22 of the support frame 2 is provided with an opening corresponding to the ejector assembly 42; the tightening plate 43 is slidably arranged on the support frame Above the opening on the frame 2, in this example, the tightening plate 43 is slidably arranged on the first slide rail 631 in the first motion structure 63; an elastic structure 73 is arranged between the tightening plate 43 and the feed plate 32, and an elastic structure 73 is also arranged between the tightening plate 43 and the first support plate 635. In this example, the elastic structure 73 is a spring, wherein connecting columns are respectively arranged between the feed plate 32 and the tightening plate 43 and between the tightening plate 43 and the first support plate 635, and one side of the connecting column of the tightening plate 43 can be fixedly arranged on the feed plate 32 or the tightening plate 43. On the other side of the tightening plate 43, the connecting column can be fixedly set on the tightening plate 43 or the first support plate 635; a spring is sleeved on the outer side of the connecting column; it should be noted that the elastic coefficient of the elastic structure 73 between the tightening plate 43 and the first support plate 635 is greater than the elastic coefficient of the elastic structure 73 between the feed plate 32 and the tightening plate 43, so that when the first support plate 635 moves, it will first push the tightening plate 43 to move toward the feed plate 32, so that the tightening plate 43 fits with the side of the feed plate 32, thereby realizing the shielding of the opening on the support frame 2 for feeding the glass rod.

[0026] The ejection assembly 42 includes an ejection plate 421, a partition plate 422, a third slide rail 423, a third slider 424 and a fifth power source 425; wherein the partition plate 422 is vertically arranged between the feeding structure 4 and the feeding structure 5 inside the support frame 2, and in this example, one side of the feeding box 41 is in contact with the partition plate 422; the third slide rail 423 is fixedly arranged on the partition plate 422, the third slide rail 423 is located in the vertical direction, and the third slider 424 is slidably arranged on the third slide rail 423; the ejection plate 421 is also fixedly arranged on the third slider 424; the top of the ejection plate 421 faces the feeding box 41; the fifth power source 425 is fixedly arranged on the ejection plate 421, and the output end of the fifth power source 425 is meshed with the vertical rack 426 arranged on the partition plate 422. When the fifth power source 425 rotates, due to the action of the meshing rack 426, the ejection plate 421 is driven to move upward or downward. The top of the ejection plate 421 is also provided with a U-shaped groove or a V-shaped groove, which is convenient for clamping the glass rod and transporting the glass rod upward.

[0027] In this example, a groove 431 corresponding to the ejector plate 421 is further provided on the side of the tightening plate 43 close to the feed plate 32, so that after the tightening plate 43 is fitted with the feed plate 32, the ejector plate 421 can be located in the groove 431, and the up and down movement of the ejector plate 421 will not be affected by the clamping of the tightening plate 43. After the ejector plate 421 moves downward, the glass rod delivered can be left above the tightening plate 43, and then the first clamping plate 61 pushed by the first moving structure 63 is pushed to a position close to the blade 1.

[0028] The second motion structure 64 includes a second slide rail 641, a second slider 642, a fourth power source 643, a second lead screw 644 and a second support plate 645; wherein the second slide rail 641 is fixedly arranged above the support frame 2, the second slider 642 is slidably arranged on the second slide rail 641; the second support plate 645 is fixedly arranged on the second slider 642, and the second clamping plate 62 is fixedly arranged on the second support plate 645; the second support plate 645 is also transmission-connected to the fourth power source 643 through the second lead screw 644. When the second motion structure 64 pushes the second clamping plate 62 to approach the rolling structure 3, the glass plate will be blocked by the second clamping plate 62 and remain in the area between the second clamping plate 62 and the first clamping plate 61, making it difficult to fall into the delivery structure 5.

[0029] The delivery structure 5 includes a delivery box, the bottom of which is also arranged as an inclined surface, so that the glass rods after the marking are conveniently rolled along the inclined surface to the designated area in the delivery box, or to leave the delivery box. In this example, the top of the delivery box contacts the bottom surface of the square plate 22 of the support frame 2, and the side of the delivery box contacts the partition plate 422. The square plate 22 of the support frame 2 is also provided with an opening corresponding to the delivery box, so that the glass rods can conveniently fall into the delivery box.

[0030] The support frame 2 is a square frame structure as a whole, and a square plate 22 for support is arranged on the top of the support frame 2; a support foot 23 with adjustable height is also arranged at the bottom of the support frame 2; in this example, there are four support feet 23, and the four support feet 23 are respectively arranged at the four corners of the bottom of the support foot 23.

[0031] The first power source 723 , the second power source 31 , the third power source 633 , the fourth power source 643 , and the fifth power source 425 are all motors.

[0032] A glass rod marking method, based on the above-mentioned marking device, comprises the following steps: Step 1: feeding the material box 41 to receive the glass rod to be scribed; Step 2: The ejection assembly 42 moves upward, and the ejection plate 421 transports a glass rod upward until the glass rod is transported to a height exceeding the first clamping plate 61; Step 3: The knife control structure 72 is activated to control the knife platform 71 to move downward by a set distance, so that the blade 1 is spaced a set distance from the rotating roller 33 in the rolling structure 3; the distance is related to the diameter of the glass rod; Step 4: The first motion structure 63 is actuated to control the first clamping plate 61 to move toward the rolling structure 3, and drives the tightening plate 43 to move toward the feed plate 32 to achieve tightening, until the first clamping plate 61 pushes the glass rod away from the ejection plate 421 and pushes it to the area of ​​the rolling structure 3; the second motion structure 64 is actuated at the same time to control the second clamping plate 62 to move to a set distance from the rotating roller 33 and stop; Step 5: The glass rod is pushed by the first clamping plate 61 to leave the top of the feed plate 32, and after moving a certain distance, it contacts the rotating roller 33 in the rolling structure 3, and rotates along with the rotation of the rotating roller 33. At the same time, the top of the glass rod abuts against the blade 1, and the scribing work is completed during the rotation of the glass rod. Step 6: After the scribing is completed, the knife control structure 72 is activated to control the knife platform 71 to move upward, and then the first motion structure 63 and the second motion structure 64 are activated to cooperate with the first clamping plate 61 and the second clamping plate 62 to push the glass rod away from the rolling structure 3 area and fall into the delivery structure 5, thus ending the step.

[0033] During the implementation process, the clamping structure 6 is provided to cooperate with the rolling structure 3 and the knife holder structure 7 to complete the automatic marking process on the side of the glass rod, which has a simple structure and high efficiency. By providing an elastic structure 73 between the knife platform 71 and the support frame 2, and cooperating with the cam in the knife control structure 72, the inclined knife plate 711 in the knife platform 71 can slide back and forth along the guide column, so as to control the height of the blade on the knife platform relative to the support frame. By providing an elastic area that is easy to deform on the knife handle, and multiple knife handles are independent of each other, on the one hand, the blade at the end of the knife handle can be better fitted with the outer side of the glass rod to complete the marking, and on the other hand, the blade on the knife handle can be fitted with glass rods with different size distributions. By providing the knife control structure 72, the knife platform 71 is controlled to move upward and downward, thereby controlling the blade 1 to approach and move away from the rolling structure 3. By providing the feeding structure 4 including the tightening plate 43, after the glass rod is fed, the tightening plate 43 can also close the opening on the support frame 2 to prevent the glass rod from falling back into the feeding box 41.
