Abstract
Description
Technical Field
[0001] This invention relates to the field of lens manufacturing technology, and in particular to a glue-tearing mechanism and a casting system. Background Technology
[0002] The lens manufacturing process requires a lens mold, which is a cylindrical structure with a pouring hole on its side wall connecting to the internal mold cavity. Adhesive tape is pasted onto the side wall of the lens mold to seal the pouring hole. Before pouring, the tape needs to be torn to expose the pouring hole. This tearing process requires a tape-tearing device, which includes a rotating mechanism and a gripper mechanism. The rotating mechanism fixes the end of the lens mold, while the gripper mechanism picks up the head of the tape. As the gripper moves away from the lens mold, the rotating mechanism drives the lens mold to rotate, thus tearing the tape. Existing tape-tearing equipment only allows movement of the gripper mechanism, which cannot meet the needs of tearing tape from lens molds of different diameters. When changing to a different diameter lens mold, either the gripper mechanism or the rotating mechanism needs to be replaced, making the operation cumbersome and reducing tape-tearing efficiency.
[0003] Therefore, it is urgent to study a glue-tearing mechanism and a casting system to solve the problem of cumbersome operation and reduced glue-tearing efficiency caused by the inability to adapt to lens molds of different diameters. Summary of the Invention
[0004] The purpose of this invention is to provide a glue-tearing mechanism and a casting system to solve the problem that the prior art cannot adapt to lens molds of different diameters, resulting in cumbersome operation and reduced glue-tearing efficiency.

[0010] The adhesive-tearing assembly includes an adhesive-tearing base, a fixed gripper, and a movable gripper. The adhesive-tearing base is slidably disposed on the mounting frame along the adhesive-tearing direction, and the angle between the adhesive-tearing direction and the vertical direction is an acute angle. The fixed gripper is disposed on the adhesive-tearing base, and the movable gripper can move closer to or further away from the fixed gripper. The clamping end of the fixed gripper extends downward and forward.
[0011] The clamping end of the fixed gripper abuts against the tearing part of the material, and the vertical plane passing through the axis of the material is located in front of the tearing part, and the material rotates backward at the tearing part.

[0014] As an optional technical solution for the adhesive-tearing mechanism, the fixed gripper is provided with a rotating part. The fixed gripper is hinged to the adhesive-tearing base through the rotating part and can rotate between the initial position and the avoidance position. The clamping end of the fixed gripper moves backward so that the fixed gripper rotates from the initial position to the avoidance position. When the fixed gripper is in the initial position, the clamping end of the fixed gripper abuts against the adhesive-tearing part of the material.
[0015] As an optional technical solution for the adhesive-tearing mechanism, the center of gravity of the fixed gripper is located on the rear side and the upper side of the rotating part, so that the fixed gripper stops at the initial position.
[0016] As an optional technical solution for the adhesive-tearing mechanism, the adhesive-tearing assembly further includes an adhesive-tearing elastic element, which is used to apply an elastic force to the fixed gripper to stop it in the initial position.

[0018] As an optional technical solution for the adhesive tearing mechanism, the fixing claw includes a claw body and a shovel part that are connected at an angle. The claw body is connected to the fixing link. The angle between the claw body and the vertical direction is A1, and the angle between the shovel part and the vertical direction is A2, where 0 < A1 < A2. The claw body and the shovel part are connected by an arc transition.
[0019] As an optional technical solution for the adhesive-tearing mechanism, the adhesive-tearing assembly further includes a detection element. The fixed gripper has a first detection hole at the clamping end, and the detection element is disposed on the fixed gripper. The detection light of the detection element can pass through the first detection hole to detect the tape attached to the fixed gripper.
[0020] As an optional technical solution for the adhesive-tearing mechanism, the movable gripper is provided with a second detection hole. When the movable gripper approaches the fixed gripper, the detection light of the detection element can pass through the first detection hole and the second detection hole.

[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0046] like Figures 1 to 9 As shown, this embodiment provides a tape-tearing mechanism 100, which tears the tape 1200 during the movement of the tape-tearing base 210 and the rotation of the fixing member 150 after the tape-tearing component 200 clamps the tape 1200, thereby exposing the casting hole. When dealing with casting molds 1100 of different diameters, it avoids the need to replace the tape-tearing component 200 or the adjusting member 130 and other parts, making the operation simple and improving the tape-tearing efficiency.
[0047] It is worth noting that the material 1000 includes a mold 1100 to be cast and adhesive tape 1200. The mold 1100 has a casting cavity and a casting hole communicating with the casting cavity. The root of the adhesive tape 1200 is attached to the mold 1100 and rotated around to seal the casting hole. Before casting, the casting hole needs to be sealed with adhesive tape 1200. During casting, the adhesive tape 1200 needs to be torn open to open the casting hole. After casting, the casting hole needs to be sealed again with adhesive tape 1200. When tearing the adhesive tape 1200, the head of the tape 1200 needs to be gripped. In this embodiment, the mold 1100 can be a lens mold for producing lenses. In other embodiments, the mold 1100 can also be other molds suitable for casting.
[0048] In some embodiments, the adhesive-tearing mechanism 100 includes a mounting frame 110, an adjusting member 130, a fixing member 150, and an adhesive-tearing assembly 200. The adjusting member 130 is disposed on the mounting frame 110; the fixing member 150 is rotatably disposed on the adjusting member 130 and is capable of picking up material 1000; the adhesive-tearing assembly 200 includes an adhesive-tearing base 210, a fixed gripper 220, and a movable gripper 230. The adhesive-tearing base 210 is slidably disposed on the mounting frame 110 along the adhesive-tearing direction N. The angle α between the tearing direction N and the vertical direction is acute. The fixed gripper 220 is located on the tearing base 210, and the movable gripper 230 can move closer to or further away from the fixed gripper 220. The gripping end of the fixed gripper 220 extends downwards and forwards. The gripping end of the fixed gripper 220 abuts against the tearing section 1300 of the material 1000. The vertical plane passing through the axis of the material 1000 is located in front of the tearing section 1300, and the material 1000 rotates backwards at the tearing section 1300. Here, the vertical direction refers to the up-and-down direction.
[0049] The above-described structure allows the adhesive-tearing mechanism 100 to adapt to materials 1000 of different diameters, expanding the applicability of the adhesive-tearing mechanism 100. Specifically, when the diameter of the material 1000 increases, the adhesive-tearing base 210 moves backward so that the adhesive-tearing component 200 comes into contact with the material 1000, thereby facilitating the scooping up of the adhesive tape 1200.
[0050] In some embodiments, the adjusting member 130 is movably disposed on the mounting bracket 110. The above-described structure allows the adjusting member 130 to operate independently or in conjunction with the adhesive-tearing assembly 200 to meet the adhesive-tearing requirements of materials 1000 with different diameters. For example, when the diameter of the material 1000 decreases, the adjusting member 130 moves backward while the adhesive-tearing base 210 remains stationary, or the adjusting member 130 moves upward while the adhesive-tearing base 210 remains stationary, or the adjusting member 130 moves backward and upward while the adhesive-tearing base 210 remains stationary, or the adjusting member 130 moves upward while the adhesive-tearing base 210 moves forward, so that the adhesive-tearing assembly 200 contacts the material 1000, thereby facilitating the scooping up of the adhesive tape 1200.
[0051] To facilitate the insertion of the clamping end of the fixing claw 220 into the gap between the tape 1200 and the mold to be poured 1100, the angle between the extending direction of the clamping end and the extending direction of the tape 1200 at the tearing part 1300 is usually an obtuse angle. When the angle between the extending direction of the clamping end and the tape 1200 is too small, such as 90°, during the process of finding the head of the tape 1200, after the clamping end of the fixing claw 220 abuts against the head of the tape 1200, the tape 1200 is prone to accumulate and be damaged as the material 1000 continues to rotate. If the angle is too large, such as 180°, it will not be able to enter the gap between the tape 1200 and the mold to be poured 1100, thus making it impossible to scoop up the tape 1200.
[0052] In some embodiments, the adjusting member 130 is slidably disposed on the mounting bracket 110 in a vertical direction. This structure allows for the adaptation to materials 1000 of different diameters and enables adjustment of the angle between the extending direction of the clamping end and the tape 1200. Specifically, when the diameter of the material 1000 decreases, the tearing base 210 moves forward, and the adjusting member 130 moves upward, so that when the tearing assembly 200 contacts the material 1000, the angle at which the clamping end of the fixing claw 220 inserts into the tape 1200 is adjusted to the optimal value, thereby facilitating the scooping up of the tape 1200. That is, the smaller the diameter of the material 1000, the smaller the distance from the point of contact between the tearing assembly 200 and the material 1000 to the standard vertical plane, which is the vertical plane passing through the axis of the material 1000. It should be noted that the optimal angle at which the clamping end of the fixing claw 220 inserts into the tape 1200 can be 100°-150°. That is, the optimal angle between the extending direction of the clamping end of the adhesive-tearing assembly 200 and the tangent of the material 1000 at the adhesive-tearing section 1300 is 100°-150°; of course, in other embodiments, it can also be determined according to the actual situation, and is not limited to the above.
[0053] In some embodiments, the tearing direction N is parallel to the tangential direction of the material 1000 at the tearing section 1300, so that after the tearing assembly 200 clamps the tape 1200, the tearing base 210 can move directly to avoid interference between the tearing assembly 200 and the mold to be poured 1100. In other words, the tearing direction N is tangent to the material 1000 at the tearing section 1300, or in other words, when the clamping end of the tearing assembly 200 abuts against the tearing section 1300 of the material 1000, the movement path of the clamping end of the tearing assembly 200 when the tearing base 210 is moved is perpendicular to the radius of the mold to be poured 1100 passing through the tearing section 1300, so as to avoid the tearing assembly 200 scraping against the mold to be poured 1100.
[0054] Generally, the outer periphery of the mold 1100 to be poured is circular. However, due to manufacturing process limitations, the outer periphery of the mold 1100 to be poured has a raised structure, i.e., a non-circular structure. To avoid interference of the raised structure with the adhesive-tearing assembly 200, in some embodiments, the fixed gripper 220 is provided with a rotating part 2211. The fixed gripper 220 is hinged to the adhesive-tearing base 210 through the rotating part 2211 and can rotate between the initial position and the avoidance position. The gripping end of the fixed gripper 220 moves backward so that the fixed gripper 220 rotates from the initial position to the avoidance position. In the initial position, the gripping end of the fixed gripper 220 abuts against the adhesive-tearing part 1300 of the material 1000.
[0055] With the above structure, during the rotation of the material 1000, the fixed gripper 220 and the adhesive tearing part 1300 on the outer periphery of the material 1000 slide and engage until the tape 1200 is scooped up. Then, the movable gripper 230 approaches the fixed gripper 220 to clamp the tape 1200. During the rotation of the material 1000, when the protruding structure on the outer periphery of the casting mold 1100 rotates to abut against the fixed gripper 220, the fixed gripper 220 flips backward to avoid interference with the protruding structure.
[0056] To ensure the fixed gripper 220 returns to its initial position, in some embodiments, the center of gravity of the fixed gripper 220 is located behind and above the rotating part 2211, so that the fixed gripper 220 stops in its initial position. The adhesive-removing base 210 is provided with a limiting part 212. When no external force is applied, under its own weight, the fixed gripper 220 rotates to its initial position and abuts against the limiting part 212, causing the gripping end of the fixed gripper 220 to tend to move forward, thus clamping the material 1000. In use, after the protruding structure of the material 1000 has rotated past, the fixed gripper 220 returns to its initial position under the action of gravity.
[0057] Combination Figure 5As shown, to ensure the fixed gripper 220 returns to its initial position, in some embodiments, the adhesive-tearing assembly 200 further includes an adhesive-tearing elastic member 240. The adhesive-tearing elastic member 240 applies an elastic force to the fixed gripper 220 to stop it in its initial position. When the fixed gripper 220 is in its initial position, its gripping end abuts against the adhesive-tearing portion 1300 of the material 1000. The adhesive-tearing base 210 is provided with a limiting portion 212, which abuts against the fixed gripper 220 when it is in its initial position. In use, after the protruding structure of the material 1000 rotates, the fixed gripper 220 returns to its initial position under the action of the adhesive-tearing elastic member 240. Furthermore, the action of the adhesive-tearing elastic member 240 ensures that the fixed gripper 220 always abuts against the adhesive-tearing portion 1300 of the material 1000, preventing it from missing the head of the adhesive tape 1200. Finally, after tearing the tape 1200, always apply an elastic force to the tape 1200. Firstly, this will keep the tape 1200 taut and prevent it from blocking the pouring hole. Secondly, it will prevent the tape 1200 from being pulled apart due to excessive force, which could cause the tape 1200 to break or the material 1000 to detach from the fixing member 150, or the tape 1200 to detach from between the fixed clamp 220 and the movable clamp 230.
[0058] Due to operational requirements, the clamping end of the fixed gripper 220 needs to be cleaned or replaced. To improve cleaning and replacement efficiency, in some embodiments, the fixed gripper 220 includes a fixed connecting rod 221 and a fixed claw 222. The fixed claw 222 is detachably connected to the fixed connecting rod 221, and a rotating part 2211 is provided on the fixed connecting rod 221. The front end of the fixed claw 222 forms the clamping end of the fixed gripper 220. This arrangement allows the fixed claw 222 to be detached from the fixed connecting rod 221 for easy cleaning. Furthermore, during the cleaning process, other fixed claws 222 can be installed for replacement, reducing the impact of the cleaning process on the work progress. Additionally, when the fixed claw 222 is damaged, it can be directly replaced, avoiding the need to replace the entire fixed gripper 220. Given the large size and complex structure of the fixed gripper 220, replacing only the fixed claw 222 reduces costs and improves maintenance efficiency to a certain extent.
[0059] To improve the effect of scooping up tape 1200, combined with Figure 8As shown, in some embodiments, the fixing claw 222 includes a claw body 2221 and a shovel portion 2222 connected at an angle. The claw body 2221 is connected to the fixing link 221. The angle between the claw body 2221 and the vertical direction is A1, and the angle between the shovel portion 2222 and the vertical direction is A2, where 0 < A1 < A2. The claw body 2221 and the shovel portion 2222 are connected by an arc transition. The angle between the shovel portion 2222 and the vertical direction is between 70° and 85°. The shovel portion 2222 forms at least part of the clamping end of the fixed gripper 220. This arrangement allows the shovel portion 2222 to have a larger angle when the adhesive tearing direction N is fixed, making it easier to shovel the shovel portion 2222 into the gap between the tape 1200 and the mold to be poured 1100. The angle of the claw body 2221 is smaller, so that the tape 1200 can bend and move upward with the claw body 2221 during the rotation of the mold to be poured 1100, and then be scooped up. Since the claw body 2221 is tilted upward and backward, it can avoid obvious creases on the tape 1200, so as to avoid the tape not being able to be pasted onto the mold to be poured 1100 later, and also prevent the tape 1200 from jumping when the movable gripper 230 is holding it.
[0060] Combination Figure 4 and Figure 6 As shown, to improve the success rate of tearing the tape 1200, in some embodiments, the tape-tearing assembly 200 further includes a detection element 250. The fixing claw 220 has a first detection hole 2223 at its clamping end. The detection element 250 is disposed on the fixing claw 220, and the detection light from the detection element 250 can pass through the first detection hole 2223 to detect the tape 1200 attached to the fixing claw 220. It should be noted that the detection principle of some light passing through the detection element 250 through the tape 1200 and some light being reflected back to detect the tape 1200 is well known to those skilled in the art, and therefore will not be described in detail here.
[0061] In actual operation, after the tape 1200 is scooped up, it forms a curled structure. As the movable gripper 230 approaches the fixed gripper 220, the tape 1200 may jump and pop out, resulting in the tape 1200 not being clamped. However, when the movable gripper 230 approaches the fixed gripper 220, the detection component cannot detect it again, making the subsequent tape-tearing process invalid. As a result, during subsequent pouring, the resin will be poured to the outside, causing contamination.
[0062] Furthermore, the movable gripper 230 is provided with a second detection hole 2321, and the light emitted by the detection element 250 can pass through the first detection hole 2223. When the movable gripper 230 approaches the fixed gripper 220, the first detection hole 2223 and the second detection hole 2321 at least partially overlap in the direction of the light emitted by the detection element 250, and the light emitted by the detection element 250 can pass through the first detection hole 2223 and the second detection hole 2321. When the fixed gripper 220 scoops up the tape 1200, the tape 1200 will block the first detection hole 2223, thereby blocking the light emitted by the detection element 250, causing light reflection, and thus determining that the tape 1200 has been scooped up. At this time, the movable gripper 230 approaches the fixed gripper 220 to clamp the tape 1200.
[0063] Because of the presence of the second detection hole 2321, light can still partially pass through and partially reflect through the tape 1200 after it is clamped, thus indicating that the tape 1200 has been successfully clamped. If the tape 1200 pops out during the clamping process, the light will pass directly through the first detection hole 2223 and the second detection hole 2321 and will not be able to pass through the tape 1200, resulting in no reflection. This indicates that the tape 1200 has failed to be clamped, and the operation can be stopped immediately, and staff can be notified or the tape can be clamped again.
[0064] Even with the second detection hole 2321, after the tape 1200 is ejected, if it adheres to the side of the movable gripper 230 away from the fixed gripper 220, light can still partially pass through the tape 1200 and be partially reflected. Therefore, the detection element 250 still has the possibility of misjudgment. To further solve the above problem, the adhesive tearing assembly 200 also includes an interceptor 260. The interceptor 260 is disposed on the movable gripper 230 and has a plate-shaped intercepting portion 261. When the movable gripper 230 is close to the fixed gripper 220, the length of the tape 1200 held between the movable gripper 230 and the fixed gripper 220 is L1, and the length of the intercepting portion 261 is L2, where L2 ≥ L1. The extending direction of the intercepting portion 261 is perpendicular to the movable gripping surface of the movable gripper 230 and parallel to the axis of the second detection hole 2321. The above configuration ensures that even if the tape 1200 pops out and is not clamped, the presence of the interceptor 261 prevents the tape 1200 from sticking to the side of the movable gripper 230 away from the fixed gripper 220. This allows light to pass directly through the second detection hole 2321, which can determine that the clamping has failed and stop the movement in time to notify the staff or clamp again.
[0065] The direction of the intercepting part 261 is such that when the movable gripper 230 moves away from the fixed gripper 220, the intercepting part 261 is located outside the extension direction of the first detection hole 2223, and will not block the light of the detection element 250.
[0066] The adhesive-tearing mechanism 100 includes a linear module 211, which is mounted on the mounting frame 110. The output end of the linear module 211 reciprocates along the adhesive-tearing direction N and is connected to the adhesive-tearing base 210 in a transmission manner.
[0067] Combination Figure 5 As shown, in some embodiments, the movable gripper 230 is hinged to the fixed gripper 220. When the movable gripper 230 is away from the fixed gripper 220, the projection of the movable gripper 230 is located outside the projection contour of the first detection hole 2223 in the extending direction of the first detection hole 2223. The adhesive tearing assembly 200 also includes a movable drive member 270, which is disposed on the fixed gripper 220 and is kinetically connected to the output end of the movable drive member 270. The above structure allows a flared structure to be formed between the movable gripper 230 and the fixed gripper 220, preventing the movable gripper 230 from blocking the tape 1200 when the fixed gripper 220 scoops it up; in addition, it facilitates the guidance of the tape 1200 so that it can enter between the fixed gripper 220 and the movable gripper 230. Finally, in the extending direction of the first detection hole 2223, the projection of the movable gripper 230 is located outside the projection contour of the first detection hole 2223, and will not block the light of the detection member 250.
[0068] In some embodiments, the movable gripper 230 includes a first plate 231 and a second plate 232 arranged at an angle, with a hinge between the first plate 231 and the second plate 232. The movable gripper 230 is hinged to the fixed gripper 220 through the hinge, and the second plate 232 can press against the clamping end to clamp the tape 1200. The movable drive member 270 includes a telescopic cylinder, the cylinder of which is hinged to the fixed gripper 220, and the piston rod of which is hinged to the first plate 231. The first plate 231 and the second plate 232 are arranged vertically, and the second detection hole 2321 and the interceptor 260 are both located on the second plate 232. This arrangement reduces the size of the movable gripper 230 in the front-rear direction, and ensures that the second detection hole 2321 is not obstructed when light passes through the detection member 250, thus guaranteeing the effectiveness of the detection.
[0069] In some embodiments, the center of gravity of the telescopic cylinder is located behind the rotating part 2211, the weight of the cylinder is greater than that of the piston rod, and the cylinder is located above the piston rod, which causes the center of gravity of the telescopic cylinder to shift upward, thereby facilitating the return of the fixed gripper 220 to its initial position and reducing the requirements for the adhesive tearing elastic element 240, thus reducing costs.
[0070] Combination Figure 2As shown, in some embodiments, the adhesive-tearing mechanism 100 includes a stop drive 280 and a stop 281. The stop drive 280 is disposed on the transfer transverse member 120, and the stop 281 is disposed at the output end of the stop drive 280 and can move between a stop position and a yield position along the stop direction. The stop 281 in the stop position is located below the adhesive-tearing assembly 200 and can press against the tape 1200 on the mold to be poured 1100. The stop 281 in the yield position is located outside the material 1000 and has a gap with the material 1000. With the help of the stop 281, when the adhesive-tearing assembly 200 tears the tape 1200, it can press against the connection between the tape 1200 and the mold to be poured 1100, so that the area of the tape 1200 torn is as small as possible, and avoids excessive tape 1200 torn and accumulating, which would interfere with the pouring hole during the pouring process. The stopping direction and the tearing direction (N) are parallel.
[0071] Alternatively, during the reverse rotation of the fixing member 150, tape 1200 can be applied to the side wall of the mold 1100 to be poured to seal the pouring hole.
[0072] Combination Figures 10 to 12 As shown, this embodiment also provides a casting system, which includes a conveying mechanism 300, a casting mechanism 400, and the aforementioned adhesive-tearing mechanism 100. The conveying mechanism 300 is used to convey material 1000; the fixing member 150 picks up material 1000 from the conveying mechanism 300; the casting mechanism 400 has a casting head 420, which is used to cast resin into the mold 1100 to be cast after the adhesive tape 1200 has been torn.
[0073] In some embodiments, the adhesive-tearing mechanism 100 further includes a lateral moving member 120 and a flipping member 140. The lateral moving member 120 is slidably disposed on the mounting bracket 110 in the left-right direction. The adjusting member 130 is slidably disposed on the lateral moving member 120 in the vertical direction. The flipping member 140 is rotatably disposed on the adjusting member 130, and its axis extends in the front-back direction. The fixing member 150 is rotatably disposed on the flipping member 140, and the flipping member 140 can rotate the axis of the fixing member 150 from the vertical direction to the left-right direction. The adhesive-tearing base 210 is slidably disposed on the lateral moving member 120 along the adhesive-tearing direction N. In this embodiment, the linear module 211 is disposed on the lateral moving member 120. The transverse drive component 121 is mounted on the mounting frame 110 and is connected to the transverse component 120 via a transmission connection; the lifting drive component 131 is mounted on the transverse component 120 and is connected to the adjusting component 130 via a transmission connection; the tilting drive component 141 is mounted on the adjusting component 130 and is connected to the tilting component 140 via a transmission connection; and the fixing drive component 151 is mounted on the tilting component 140 and is connected to the fixing component 150 via a transmission connection. When the axis of the fixing component 150 moves to the left or right direction, the adhesive-tearing action is initiated. This configuration allows the adhesive-tearing action to be performed simultaneously during the movement of the transverse component 120, resulting in partial overlap between the transfer of material 1000 and the adhesive-tearing process, thus improving casting efficiency to a certain extent.
[0074] Generally, the axis of the gating hole is perpendicular to the axis of the mold 1100 to be cast. In some different product models, the axis of the gating hole is not perpendicular to the axis of the mold. Due to the presence of the flipper 140, after the tape 1200 is torn, the flipper 140 can be rotated at a certain angle so that the axis of the gating hole extends in the vertical direction to facilitate casting.
[0075] The fixing component 150 is a suction cup that can adhere to the end of the mold 1100 to be poured. On the conveying mechanism 300, the axis of the material 1000 extends in the vertical direction; when the adhesive is peeled off, the axis of the material 1000 extends in the horizontal direction.
[0076] The conveying mechanism 300 includes a production line. When the material 1000 is conveyed on the production line, its axis extends vertically. After the fixing member 150 adsorbs the end face of the material 1000, the flipping member 140 rotates, thereby causing the axis of the material 1000 to extend horizontally. Then, in conjunction with the fixed gripper 220 and movable gripper 230 of the adhesive tearing mechanism 100, the adhesive tape 1200 is torn. After the adhesive tape 1200 is torn, the pouring hole of the mold 1100 to be poured is exposed. Under the action of the transverse member 120, the mold 1100 to be poured is transferred to the bottom of the pouring head 420. The pouring head 420 pours resin into the mold 1100 to be poured. After the pouring is completed, the adhesive tearing base 210 is moved in the opposite direction and the fixing member 150 is rotated in the opposite direction, so that the adhesive tape 1200 can be stuck on the pouring hole and a casting part is formed. The entire process eliminates the need for positioning the casting mold 1100, improving casting efficiency and reducing positioning mechanisms, thus lowering costs.
[0077] Combination Figure 11 As shown, specifically, the conveying mechanism 300 includes a first production line 310, a second production line 320, and a transfer assembly 330. The first production line 310 is used to move the material 1000 from the first loading position to the first unloading position. The transfer assembly 330 is used to transfer the material 1000 from the first unloading position to the transfer position. The second production line 320 is used to transfer the casting from the second loading position to the second unloading position. The fixing member 150 of the adhesive peeling assembly 200 can pick up the material 1000 from the transfer position and transfer the casting to the second loading position. The transfer assembly 330 includes a transfer base 331 and a double-headed cylinder 332 located below the transfer base 331. Each of the two output ends of the double-headed cylinder 332 has two positioning elements 333. The four positioning elements 333 extend vertically and are located around the transfer base 331. The two output ends of the double-headed cylinder 332 extend and retract to bring the four positioning elements 333 closer together or further apart. When the four positioning elements 333 are close together, they can position the material 1000 on the transfer base 331 to the transfer position. The transfer assembly 330 also includes a transfer bracket 334 and a transfer member 335. The transfer bracket 334 is located between the first production line 310 and the second production line 320. The transfer member 335 slides along the transfer bracket 334 in the left-right direction and can transfer between the first production line 310 and the transfer base 331 to transfer the material 1000 on the first production line 310 to the transfer base 331.
[0078] The transfer member 335 includes a transfer connecting part 3351, a transfer actuating part 3352 and a transfer blocking part 3353 disposed on the transfer connecting part 3351. The transfer blocking part 3353 is used to stop the material 1000 on the first production line 310, and the transfer actuating part 3352 is used to transfer the material 1000 from the first production line 310 to the transfer seat 331 when the transfer member 335 moves to the right.
[0079] To accommodate materials 1000 of different diameters, in some embodiments, the casting mechanism 400 includes a casting support 410, wherein the casting head 420 is slidably disposed on the casting support 410 in a vertical direction.
[0080] Combination Figure 12 As shown, the casting mechanism 400 also includes an illumination element 430 and an identification element 440. The identification element 440 is slidably disposed on the casting support 410 in the vertical direction, and the illumination element 430 is movably disposed on the casting support 410 to illuminate the material 1000. During the process of the adhesive tearing mechanism 100 carrying the casting mold 1100 to the right, after the identification element 440 identifies the root of the adhesive tape 1200, the casting mold 1100 continues to move so that the casting hole located in front of the root of the adhesive tape 1200 is directly below the casting head 420.
[0081] The casting drive component 421 is located on the casting support 410. The output end of the casting drive component 421 can move vertically and is connected to the casting head 420 and the identification component 440. The lighting drive component is located on the casting support 410, and the lighting component 430 is located at the output end of the lighting drive component. The lighting drive component drives the lighting component 430 to move closer to or further away from the casting head 420 to accommodate different diameter molds 1100 to be cast, and can also avoid obstruction when the mold 1100 to be cast moves to the casting position. This arrangement allows the casting head 420 to move upwards to accommodate upwardly moving casting holes as the diameter of the material 1000 increases, thus accommodating materials 1000 of different diameters.
[0082] In some embodiments, the casting mechanism 400 further includes a camera 450, which is used to photograph the mold 1100 to be cast and the casting head 420 during casting to analyze whether the position of the mold 1100 to be cast is accurate. The camera 450 is located to the right of the casting head 420 and is mainly used to determine the distance between the casting head 420 and the casting hole in the left-right direction.
