Description

Technical Field

[0001] The present invention relates to the technical field of optical glass production and processing, and more specifically, to an on-line continuous cutting device for optical glass strips. Background Art

[0002] In the existing optical glass production and processing field, it is usually necessary to first cut the formed optical glass strip into optical glass blocks of corresponding sizes, so as to facilitate further processing of the optical glass blocks into corresponding optical lenses. Among them, in the last process of optical glass production, the molten glass liquid will flow through the discharge pipe into the forming die for forming, and after annealing in the traction furnace, it will be cut into optical glass blocks of the required size.

[0003] At present stage, the cutting of optical glass strips is often still completed manually with the help of auxiliary tools such as calipers and glass knives. During cutting, one end of the caliper is abutted against the end of the optical glass strip by the operator, and the position of the other end of the caliper determines the length of the optical glass block. At this time, the operator uses the glass knife to cut on the surface of the optical glass strip along the direction perpendicular to the conveying path of the optical glass strip with the caliper as a reference, so as to form a cutting line on the surface of the optical glass strip. Subsequently, the operator sprays a low-temperature fluid medium such as compressed air along the cutting line onto the optical glass surface with the help of a nozzle, so that the optical glass strip is locally cooled. Finally, the operator gently taps the cut optical glass strip. At this time, the optical glass strip breaks along the cutting line under the action of internal stress and external force, so as to cut out optical glass blocks of corresponding sizes.

[0004] However, since in the actual cutting process, the optical glass strip to be cut is always located on the conveying mechanism of the traction furnace and is in a slow moving state, therefore, the method of using the caliper as a reference and manually completing the cutting is greatly affected by human factors, and often makes the cut side of the optical glass strip be an inclined side instead of a straight side. At the same time, the method of manual cutting not only has a large labor intensity but also a low cutting efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0034] Example 1

[0035] Please refer to Figures 1 to 5 This embodiment provides an online continuous cutting device for optical glass strips, which at least overcomes the technical problems that the optical glass strips 100 cut manually in the prior art cannot ensure that the cut side of the optical glass strips 100 is straight, the manual labor intensity is high, and the cutting efficiency is low. Specifically, the cutting device includes a conveying mechanism 10, a cutting mechanism 20, and a supporting mechanism 30, so as to complete the cutting of the optical glass strips 100 through the cooperation of the three.

[0036] In this embodiment, the conveying mechanism 10 is used to convey the optical glass strip 100 to be cut at a certain conveying speed. It can be understood that the conveying mechanism 10 is a conveying mechanism 10 provided with an existing traction furnace for annealing the optical glass strip 100. The annealed optical glass strip 100 is conveyed by the conveying mechanism 10 and output through the discharge port of the traction furnace, so that the optical glass strip 100 can be cut by the cutting mechanism 20 later.

[0037] In this embodiment, the cutting mechanism 20 is disposed on the conveying path of the conveying mechanism 10 . Preferably, the cutting mechanism 20 can be disposed at the end of the conveying mechanism 10 so as to cut the optical glass strip 100 into optical glass blocks 200 of corresponding sizes through the cutting mechanism 20 .

[0038] Specifically, the cutting mechanism 20 includes a cutting tool 21, a fixed seat 22, a mounting seat 23, a driving motor 24, a driving rack 25, a pressing-down assembly 26, and a blowing pipe 27. Among them, the cutting tool 21 can be, but is not limited to, a conventional glass cutter in the prior art. At this time, the cutting tool 21 can cut the optical glass strip 100 along a cutting path at a certain cutting speed to form a cutting line on the surface of the optical glass strip 100.

[0039] Considering that when the optical glass strip 100 is cut manually in the prior art, since the optical glass strip 100 is always in a slow moving state, if the cutting path is perpendicular to the conveying path of the conveying mechanism 10, it may make the cut side of the optical glass strip 100 be an inclined side, affecting the overall aesthetics of the product and being not conducive to subsequent processing.

[0040] Therefore, please refer to Figure 2 , in this embodiment, the cutting path of the cutting tool 21 is arranged at an angle with the conveying path of the conveying mechanism 10. At this time, the angle between the cutting path of the cutting tool 21 and the conveying path of the conveying mechanism 10 is defined as θ, the cutting speed of the cutting tool 21 is V1, and the conveying speed of the conveying mechanism 10 is V2. Then: V2 / V1 = cosθ. It can be understood that the above angle θ can be set as an acute angle such as 15°, 30°, 60°, etc.

[0041] With such a setting, based on the fact that the cutting speed V1 of the cutting tool 21 and the conveying speed V2 of the conveying mechanism 10 satisfy V2 / V1 = cosθ, during the actual cutting process, the component speed of the cutting speed V1 of the cutting tool 21 in the direction of the conveying path of the conveying mechanism 10 is the same as the conveying speed V2 of the conveying mechanism 10. At this time, the cutting tool 21 will cut the optical glass strip 100 vertically relative to the slowly moving optical glass strip 100, so that the cut side of the optical glass strip 100 is a straight side instead of an inclined side after cutting.

[0042] In order to drive the cutting tool 21 to move along the cutting path, in combination with Figure 1 and Figure 3As shown in the figure, the above-mentioned fixed seat 22 is fixedly arranged on the bracket of the conveying mechanism 10, and the fixed seat 22 is provided with a notch for the optical glass strip 100 to pass through. The mounting seat 23 is slidably arranged on the fixed seat 22. For example, a slide rail extending along the cutting path of the cutting knife 21 can be arranged on the fixed seat 22, and the mounting seat 23 is slidably arranged on the slide rail to realize the sliding connection between the mounting seat 23 and the fixed seat 22. At this time, the cutting knife 21 is arranged at the bottom of the mounting seat 23, the driving motor 24 is arranged at the top of the mounting seat 23, the output end of the driving motor 24 faces downward and is drivingly connected with a driving gear 28. The driving rack 25 is arranged on the fixed seat 22 and extends along the cutting path of the cutting knife 21, and the driving gear 28 meshes with the driving rack 25.

[0043] With such a setting, when the optical glass strip 100 needs to be cut, the driving motor 24 works to drive the driving gear 28 to rotate. At this time, the driving gear 28 will drive the driving motor 24 and the mounting seat 23 to move along the driving rack 25. Since the driving rack 25 extends along the cutting path of the cutting knife 21, the moving mounting seat 23 will drive the cutting knife 21 to move along the cutting path to complete the cutting of the optical glass strip 100. Preferably, the above-mentioned driving motor 24 can adopt a servo motor with high control precision, and the driving of the mounting seat 23 is realized by the cooperation of the gear and the rack, so that the cutting process is more stable and it is convenient to control the cutting stroke of the cutting knife 21.

[0044] In order to realize the explosion cutting of the optical glass strip 100, two pressing components 26 and a blowing pipe 27 are additionally arranged in the cutting mechanism 20 of this embodiment. Among them, the pressing component 26 is used to gently knock the surface of the optical glass strip 100 after the cutting knife 21 cuts a cutting line on the surface of the optical glass strip 100, so that the optical glass strip 100 can break along the cutting line, and then the optical glass block 200 is obtained. The blowing pipe 27 is used to blow low-temperature fluid media such as compressed air to the surface of the optical glass strip 100 at the cutting line after the cutting knife 21 cuts, so as to realize the local cooling of the optical glass strip 100, which is beneficial to the subsequent breaking of the optical glass strip 100 along the cutting line.

[0045] Specifically, in combination with Figure 3 and Figure 4 As shown in the figure, the two pressing components 26 are symmetrically arranged on both sides of the cutting knife 21 with the cutting path of the cutting knife 21 as the axis, that is, the cutting line formed after the cutting knife 21 cuts on the surface of the optical glass strip 100 is located between the two pressing components 26, so as to respectively knock the optical glass strip 100 on both sides of the cutting line by the two pressing components 26, which is beneficial to the breaking of the optical glass strip 100 along the cutting line.

[0046] Continue to refer to Figure 4, the pressing-down assembly 26 includes a pressing-down air cylinder 261 and a pressing cylinder 262. The pressing-down air cylinder 261 is arranged on the mounting base 23, and the pressing cylinder 262 is rotatably arranged at the output end of the pressing-down air cylinder 261. The axis of the pressing cylinder 262 is parallel to the cutting path of the cutting knife 21. The pressing-down air cylinder 261 is used to drive the pressing cylinder 262 to move in the vertical direction.

[0047] Based on the fact that the optical glass strip 100 to be cut is always in a slow movement state. Therefore, by rotatably arranging the pressing cylinder 262 at the output end of the pressing-down air cylinder 261, when the pressing-down air cylinder 261 drives the pressing cylinder 262 to move downward and contact the surface of the optical glass strip 100 to strike the optical glass strip 100, the friction between the pressing cylinder 262 and the surface of the optical glass strip 100 can be effectively reduced, and the situation that the pressing cylinder 262 scratches the surface of the optical glass strip 100 can be avoided.

[0048] At the same time, in combination with Figure 3 and Figure 4 the content shown, the air blowing pipe 27 is also arranged on the mounting base 23. The air outlet end of the air blowing pipe 27 (i.e., Figure 3 the bottom end of the air blowing pipe 27 shown in

[0049] ) faces the optical glass strip 100 and corresponds to the cutting path of the cutting knife 21. The air inlet end of the air blowing pipe 27 can be connected to an external air supply device to use the air supply device to convey low-temperature fluid media such as compressed air to the air blowing pipe 27. At this time, the cutting knife 21, the air blowing pipe 27 and the pressing-down assembly 26 are arranged in sequence along the cutting path of the cutting knife 21.

[0050] Considering that the cutting tool 21 needs to return to the initial position after completing one cutting operation for the next cutting operation, in order to avoid interference between the cutting tool 21 and the uncut optical glass strip 100 on the conveying mechanism 10 when the cutting tool 21 returns to the initial position, please refer to Figure 4 , the mounting seat 23 has an inner cavity, and an installation plate 29, a lifting rod 210, a rotating shaft 211 and a lifting motor 212 are arranged in the inner cavity of the mounting seat 23. A guiding block 213 is arranged on the installation plate 29. The bottom end of the lifting rod 210 vertically penetrates through the guiding block 213 and then extends to the outside of the mounting seat 23 and is connected to the cutting tool 21. The lifting rod 210 is slidably connected with the guiding block 213 so that the lifting rod 210 can freely slide in the vertical direction. At this time, the output end of the lifting motor 212 is drivingly connected with one end of the rotating shaft 211, and the other end of the rotating shaft 211 is connected with a lifting gear 214. At the same time, a lifting rack 215 extending along its axial direction is arranged on the outer wall of the lifting rod 210, and the lifting gear 214 meshes with the lifting rack 215.

[0051] It can be understood that, in combination with Figure 4 As shown in the figure, in this embodiment, two oppositely arranged guiding blocks 213 are arranged on the installation plate 29, and a limiter is arranged at the top end of the lifting rod 210. On the basis of improving the stability of the lifting rod 210 during movement, the movement stroke of the lifting rod 210 can be limited by the limiter. At the same time, in order to avoid interference between the lifting rack 215 and the guiding block 213 during movement, a notch adapted to the lifting rack 215 is arranged on the guiding block 213 so that the lifting rack 215 can pass through the notch.

[0052] With such a setting, when the lifting motor 212 works to drive the lifting gear 214 to rotate, the lifting rack 215 can move in the vertical direction under the action of the lifting gear 214, so as to drive the lifting rod 210 together with the cutting tool 21 to move in the vertical direction through the lifting rack 215. At this time, the height of the cutting tool 21 can be changed, so that the cutting tool 21 can return to the initial position driven by the mounting seat 23, and it is convenient to adjust the cutting depth of the cutting tool 21 when cutting the optical glass strip 100 according to actual processing needs.

[0053] In this embodiment, the supporting mechanism 30 is also arranged at the end of the conveying mechanism 10 to support the optical glass strip 100 to be cut through the supporting mechanism 30 and carry the formed optical glass block 200 after cutting. Specifically, please refer to Figure 1 , the supporting mechanism 30 includes a supporting platform 31 and a supporting component 32. The supporting platform 31 can be fixedly arranged on the bracket at the end of the conveying mechanism 10, and the top surface of the supporting platform 31 is in the same horizontal plane as the bottom surface of the optical glass strip 100 conveyed on the conveying mechanism 10, so that the optical glass strip 100 can move from the conveying mechanism 10 to the supporting platform 31.

[0054] Please refer to Figure 5 Figure 5 , the support assembly 32 includes a support roller 321, a support bracket 322, and a support cylinder 323. The support roller 321 is rotatably arranged on the support bracket 322. The support roller 321 is located between the conveying mechanism 10 and the support platform 31. The axis of the support roller 321 is perpendicular to the conveying path of the conveying mechanism 10. The support cylinder 323 is arranged below the support bracket 322 and is used to drive the support bracket 322 to move in the vertical direction.

[0055] It can be understood that, in combination with Figure 1 and Figure 5 Figure 5 shown, an installation bracket 324 can be provided at the bottom of the bracket of the conveying mechanism 10, and the support cylinder 323 can be fixedly arranged on the installation bracket 324. And a guide post 325 can be provided at the bottom of the support bracket 322. One end of the guide post 325 is connected to the support bracket 322, and the other end of the guide post 325 is slidably connected to the installation bracket 324 to improve the stability of the support bracket 322 when moving in the vertical direction.

[0056] With such a setting, before the cutting operation, first use the support cylinder 323 to drive the support bracket 322 to move upward so that the top surface of the support roller 321, the bottom surface of the optical glass strip 100 conveyed on the conveying mechanism 10, and the top surface of the support platform 31 are in the same horizontal plane. During the cutting operation, the optical glass strip 100 conveyed on the conveying mechanism 10 moves to the support platform 31 after passing through the support roller 321. At this time, the cutting mechanism 20 can be used to cut the optical glass strip 100. By providing the freely rotatable support roller 321, the optical glass strip 100 can smoothly move to the support platform 31 and provide reliable support for the optical glass strip 100.

[0057] Meanwhile, continue to refer to Figure 1 Figure 1 , two in-place detectors 33 are provided on the support platform 31. The two in-place detectors 33 are symmetrically arranged on both sides of the support platform 31 with the conveying path of the conveying mechanism 10 as the axis. The two in-place detectors 33 can judge the position of the optical glass strip 100. When the end of the optical glass strip 100 to be cut moves to the position where the two in-place detectors 33 are located, the two in-place detectors 33 can timely feedback the corresponding position information so that the cutting mechanism 20 can make a timely response to cut the optical glass strip 100. It can be understood that the in-place detector 33 can but is not limited to using a conventional photoelectric sensor.

[0058] In order to more clearly and intuitively understand the online continuous cutting device provided in this embodiment, the working principle of the cutting device will be further elaborated below.

[0059] In the initial state, the top surface of the support roller 321 of the support mechanism 30 and the top surface of the support platform 31 are both in the same horizontal plane as the bottom surface of the optical glass strip 100 on the conveying mechanism 10, and the mounting base 23 of the cutting mechanism 20 is located on one side of the optical glass strip 100.

[0060] When the optical glass strip 100 on the conveying mechanism 10 moves along the support roller 321 to the support platform 31 and reaches the positions of the two in-place detectors 33, the drive motor 24 of the cutting mechanism 20 is started. At this time, the mounting base 23 moves along the cutting path of the cutting knife 21 under the combined action of the drive gear 28 and the drive rack 25, so as to drive the cutting knife 21 to cut the surface of the optical glass strip 100 along the cutting path at a certain cutting speed, and cut a cutting line on the surface of the optical glass strip 100. Based on the further limitation of the cutting path and cutting speed of the cutting knife 21 in this embodiment, the cutting line finally formed on the surface of the optical glass strip 100 by the cutting knife 21 is a straight line and perpendicular to the moving direction of the optical glass strip 100.

[0061] As the mounting base 23 continues to move along the cutting path, when the mounting base 23 drives the air blowing pipe 27 to move above the optical glass strip 100, an external air supply device introduces a low-temperature fluid medium such as compressed air into the air blowing pipe 27, so as to blow the low-temperature fluid medium such as compressed air to the optical glass strip 100 near the cutting line through the air blowing pipe 27, thereby locally cooling the optical glass strip 100. Correspondingly, when the two pressing components 26 are driven by the mounting base 23 to move above the optical glass strip 100 and the cutting knife 21 finishes cutting the optical glass strip 100, the cutting line on the surface of the optical glass strip 100 is between the two pressing components 26. At this time, the pressing cylinders 261 of the two pressing components 26 simultaneously drive the corresponding pressing cylinders 262 to move downward, so as to gently knock the optical glass strip 100 on both sides of the cutting line through the pressing cylinders 262 of the two pressing components 26, thereby causing the optical glass strip 100 to break along the cutting line, and then obtaining the optical glass block 200 of the corresponding size.

[0062] Thus, a cutting operation is completed. At this time, the cut optical glass blocks 200 can be transferred away manually or by setting a palletizing robot, so as to centrally transfer the optical glass blocks 200 to the next working station for processing.

[0063] After the first cutting operation is completed, the lifting motor 212 in the mounting seat 23 operates to drive the lifting gear 214 to rotate through the lifting motor 212. At this time, the lifting rack 215 will drive the lifting rod 210 to move upward so that the cutting tool 21 is away from the optical glass strip 100. Subsequently, the driving motor 24 drives the driving gear 28 to rotate in the reverse direction, so that the mounting seat 23 can move in the reverse direction to the initial position. When the mounting seat 23 moves to the initial position, the lifting motor 212 drives the lifting gear 214 to rotate in the reverse direction again, so that the cutting tool 21 moves downward to the initial position, thereby preparing for the next cutting.

[0064] It can be seen that the on-line continuous cutting device for optical glass strips provided by this embodiment can replace manual cutting of the optical glass strip 100 by adding a cutting mechanism 20 that integrates cutting, blowing, and knocking functions, improving the cutting efficiency of the optical glass strip 100 while reducing the labor intensity of workers.

[0065] At the same time, by limiting the cutting path and cutting speed of the cutting tool 21, the cutting line formed by the cutting tool 21 on the surface of the optical glass strip 100 can be a straight line, so that the edge of the cut optical glass block 200 is a straight edge, which is beneficial to further processing of the optical glass block 200 on the basis of improving the aesthetics of the optical glass block 200.

[0066] Embodiment 2

[0067] On the basis of Embodiment 1, considering that the finally cut optical glass block 200 in Embodiment 1 still needs to be transferred to the transfer vehicle 300 by manual or palletizing manipulator, manual transfer not only has a large labor intensity but also a low transfer efficiency, while using a palletizing manipulator for transfer has a high cost and is not conducive to actual implementation.

[0068] Therefore, please refer to Figures 6 to 7 , the on-line continuous cutting device provided by this embodiment further includes a transfer mechanism 40, which is used to transfer the cut optical glass block 200 on the support platform 31 to the transfer vehicle 300, improving the transfer efficiency while minimizing the input cost.

[0069] Specifically, the transfer mechanism 40 includes a fixed bracket 41, a transfer cylinder 42, a pushing cylinder 43, a bearing table 44, two protective plates 45, and a pushing plate 46. Referring to Figure 6As shown in the figure, the fixing bracket 41 is arranged at one end of the support mechanism 30 away from the conveying mechanism 10. The transfer cylinder 42 is arranged on the fixing bracket 41. The output end of the transfer cylinder 42 extends in the vertical direction and is connected to the bottom of the bearing platform 44, so as to drive the bearing platform 44 to move in the vertical direction through the transfer cylinder 42. The two protective plates 45 are symmetrically distributed on the top surface of the bearing platform 44 with the conveying path of the conveying mechanism 10 as the axis. The pushing cylinder 43 is arranged below the bearing platform 44 and on one side of the bearing platform 44. The output end of the pushing cylinder 43 extends in the horizontal direction and is connected to the pushing plate 46, so as to drive the pushing plate 46 to reciprocate in the horizontal direction through the pushing cylinder 43.

[0070] With such an arrangement, in the initial state, the transfer cylinder 42 drives the bearing platform 44 to move upward, so that the top surface of the bearing platform 44 is in the same horizontal plane as the top surface of the support platform 31, and the gap between the bearing platform 44 and the support platform 31 is as small as possible. After a piece of optical glass blank 200 is cut on the support platform 31, since the uncut optical glass strip 100 is always in a slow movement state, the optical glass strip 100 will push the cut optical glass blank 200 to continue moving in the direction of the bearing platform 44. Finally, the optical glass blank 200 will move onto the bearing platform 44 and be just located between the two protective plates 45, so as to limit two degrees of freedom of the optical glass blank 200 in the horizontal direction through the two protective plates 45.

[0071] After a piece of optical glass blank 200 moves onto the bearing platform 44, the transfer cylinder 42 drives the bearing platform 44 to move downward, and the moving distance is equal to the thickness of a piece of optical glass blank 200. At this time, the top surface of the optical glass blank 200 on the bearing platform 44 is in the same horizontal plane as the top surface of the support platform 31, so as to facilitate the next piece of optical glass blank 200 to move from the support platform 31 to the bearing platform 44 and stack on the optical glass blank 200 below.

[0072] And so on. After the optical glass blanks 200 on the bearing platform 44 are stacked to a certain number, the transfer cylinder 42 drives the bearing platform 44 to move downward until the top surface of the bearing platform 44 is in the same horizontal plane as the top surface of the transfer cart 300 placed in advance at the fixing bracket 41, and the pushing plate 46 is just facing the stacked optical glass blanks 200 on the bearing platform 44. Subsequently, the pushing cylinder 43 drives the pushing plate 46 to move in the direction of the bearing platform 44, so as to push the stacked optical glass blanks 200 on the bearing platform 44 onto the transfer cart 300 through the pushing plate 46. Repeat the above operations. After the optical glass blanks 200 on the transfer cart 300 reach a certain number, the transfer cart 300 together with the optical glass blanks 200 can be transferred to the next working station by manual.

[0073] It should be noted that, based on the fact that the optical glass strip 100 on the conveying mechanism 10 is always in a slow movement state, the time interval between two cuts is relatively long. At this time, during the continuous conveying of the optical glass strip 100 by the conveying mechanism 10, the gap between two cuts can be fully utilized to complete the operation of driving the carrier table 44 to move downward by the transfer cylinder 42 and enabling the pushing cylinder 43 to push the optical glass block 200 on the carrier table 44 onto the transfer vehicle 300. That is, during the process of transferring the stacked optical glass blocks 200 on the carrier table 44 to the transfer vehicle 300, it is not necessary to stop the conveying mechanism 10, thereby realizing the continuous transfer of the cut optical glass blocks 200.

[0074] On the other hand, considering that in the actual production process, the optical glass strips 100 to be cut often have various different widths. At this time, in order to enable the carrier table 44 to carry optical glass blocks 200 with various different widths, please refer to Figure 7 , in this embodiment, the two protective plates 45 are slidably arranged on the top surface of the carrier table 44. The sliding paths of the protective plates 45 are perpendicular to the conveying path of the conveying mechanism 100, that is, the two protective plates 45 can approach or move away from each other. Guide plates 47 are arranged on the sides of the two protective plates 45 close to the support mechanism 30. The two guide plates 47 are arranged in a horn shape, and the connection between the guide plate 47 and the protective plate 45 is in an arc transition structure, so as to play a certain guiding role through the guide plates 47, which is beneficial to the smoothly movement of the cut optical glass blocks 200 on the support platform 31 to the carrier table 44.

[0075] At the same time, continue to refer to Figure 7 , a contraction assembly 48 corresponding to the protective plate 45 is further arranged on the top surface of the carrier table 44. The contraction assembly 48 includes a fixed block 481 and a spring 482. The fixed block 481 is located outside the protective plate 45, and the spring 482 is located between the protective plate 45 and the fixed block 481. One end of the spring 482 is connected to the fixed block 481, and the other end of the spring 482 is connected to the protective plate 45. It can be understood that the number of springs 482 of each contraction assembly 48 can be one or more. When there are multiple springs 482, the multiple springs 482 are evenly distributed at a certain interval, so that the force when the optical glass block 200 pushes the protective plate 45 is more uniform. For example, in this embodiment, two springs 482 are provided for each contraction assembly 48.

[0076] With such a setting, when the optical glass blank 200 on the support platform 31 moves towards the direction where the bearing platform 44 is located, the optical glass blank 200 is always located between the two guide plates 47 under the guiding action of the two guide plates 47. If the width of the optical glass blank 200 is greater than the distance between the two protection plates 45, when the optical glass blank 200 moves onto the bearing platform 44, both sides of the optical glass blank 200 respectively push against the two protection plates 45, so that the two protection plates 45 move away from each other, and the springs 482 corresponding to the outer sides of the protection plates 45 will contract. After the optical glass blank 200 completely moves onto the bearing platform 44, the two protection plates 45 clamp the optical glass blank 200 to improve the stability of the optical glass blank 200. Thus, it can be seen that by adding the contraction assembly 48, it is possible to be applicable to transporting optical glass blanks 200 of various different width dimensions, thereby improving the practicability of the transfer mechanism 40.

[0077] In addition, in order to prevent the optical glass blank 200 moving onto the bearing platform 44 from falling off the bearing platform 44 and to make the optical glass blanks 200 stacked on the bearing platform 44 more neatly arranged, continue to refer to Figure 6 , a baffle 49 is further provided on the fixed bracket 41. The baffle 49 is located on the side of the bearing platform 44 away from the support mechanism 30. The sides of the two protection plates 45 away from the support mechanism 30 are both in contact with the wall of the baffle 49. The bottom end of the baffle 49 extends vertically downward to a position above the position where the jacking cylinder 43 is located.

[0078] That is to say, when the bearing platform 44 receives the optical glass blank 200 on the support platform 31, the end of the optical glass blank 200 away from the uncut optical glass strip 100 will move to the position where the baffle 49 is located and contact the wall of the baffle 49, so as to use the baffle 49 to block the optical glass blank 200. And under the limiting action of the baffle 49, when the next and upper optical glass blank 200 moves on the top surface of the lower optical glass blank 200, it is also impossible to change the position of the lower optical glass blank 200. And when the transfer cylinder 42 drives the bearing platform 44 to move downward, it can make multiple optical glass blanks 200 always neatly stacked on the bearing platform 44 until the transfer cylinder 42 drives the bearing platform 44 to move to the position of the jacking cylinder 43, and the optical glass blank 200 on the bearing platform 44 just breaks away from the contact with the baffle 49, so as to facilitate using the jacking plate 46 to push the optical glass blank 200 on the bearing platform 44 onto the transfer vehicle 300.

[0079] Thus, it can be seen that in this embodiment, by further adding the transfer mechanism 40, it is possible to transfer the cut optical glass blanks 200 on the support platform 31 onto the transfer vehicle 300. At this time, it only needs to manually transfer the transfer vehicle 300 to the next working station, effectively reducing the labor intensity of the workers, and compared with using a palletizing manipulator for transfer, the cost is greatly reduced.

[0080] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
