Description

One end of the adhesive tape is bonded to the two single molds as a root portion, and then the adhesive tape is rotated one turn to seal the pouring hole.

[0003] During lens production, a transfer device is generally used to transport the lens mold. After positioning on the transfer device, the lens mold is grasped by the transfer device, and then transferred to a film tearing device.

[0051] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0052] As shown in Figures 1 to 12 The present embodiment provides a lens pouring device for pouring resin into a to-be-poured mold 1100 to form a lens of resin material. After the material 1000 is obtained, the adhesive tape 1200 is torn, the resin is poured, and the completed mold is placed on the conveying mechanism 100, all without leaving the fixing member 250 on the transfer mechanism 200, especially the process of tearing the adhesive tape 1200, without setting a positioning mechanism, reducing the positioning frequency, improving the pouring efficiency; in addition, reducing the positioning mechanism is also conducive to reducing the cost.

[0053] It is worth mentioning that the material 1000 includes a to-be-poured mold 1100 and a tape 1200, the to-be-poured mold 1100 has a pouring cavity and a pouring hole communicating with the pouring cavity, the root of the tape 1200 is pasted on the to-be-poured mold 1100 and is pasted for one turn in rotation, and the tape 1200 can block the pouring hole. The to-be-poured mold 1100 needs to be closed by the tape 1200 before pouring, the tape 1200 needs to be torn to open the pouring hole during pouring, and the pouring hole needs to be closed by the tape 1200 again after pouring. When the tape 1200 is torn, the head of the tape 1200 needs to be clamped. In the embodiment, the to-be-poured mold 1100 can be a lens mold for producing lenses, and in other embodiments, the to-be-poured mold 1100 can also be other molds that can be used for pouring forming.

[0054] In the embodiment, the lens pouring device includes a conveying mechanism 100, a transfer mechanism 200 and a pouring mechanism 300. The conveying mechanism 100 is used to convey the material 1000. The transfer mechanism 200 includes a transfer fixing seat 210, a fixing member 250 and a tape tearing assembly 400 arranged on the transfer fixing seat 210. The transfer mechanism 200 can fix the material 1000 through the fixing member 250, and can move the material 1000 between the conveying mechanism 100 and a pouring position. The tape tearing assembly 400 is used to tear the tape 1200 on the to-be-poured mold 1100 to expose the pouring hole of the to-be-poured mold 1100, or to paste the tape 1200 to the pouring hole of the to-be-poured mold 1100 to form a pouring piece after pouring is completed. The pouring mechanism 300 has a pouring head 320, which pours through the pouring hole to the to-be-poured mold 1100 located at the pouring position.

[0055] With the above structure, the material 1000 can be conveyed by the conveying mechanism 100 to supply the material 1000 to the transfer mechanism 200, and the pouring piece after pouring is completed can be transferred to the next station. After the tape 1200 is torn by the transfer mechanism 200, the to-be-poured mold 1100 is moved to the pouring position and poured by the pouring mechanism 300. The whole process is completed by one lens pouring device, the positioning requirement during transfer between multiple devices is reduced, the pouring efficiency is improved, and the reduction of the positioning mechanism also helps to reduce the cost.

[0056] As Figures 1 to 4As shown, since the material 1000 is a cylindrical structure with a height less than a diameter, the overall shape is flat, the axis of the pouring hole is perpendicular to the axis of the material 1000, and the opening of the pouring head 320 faces downward. In some embodiments, in order to facilitate transportation and pouring, the transfer mechanism 200 includes a turnover driving member 241 and a transfer turnover member 240. The turnover driving member 241 is arranged on the transfer fixing seat 210, the transfer turnover member 240 is rotatably arranged on the transfer fixing seat 210 and is in transmission connection with the output end of the turnover driving member 241, and the fixing member 250 is arranged on the transfer turnover member 240. The transfer turnover member 240 rotates between a first turnover position and a second turnover position to rotate the axis of the material 1000 from a vertical direction to a left-right direction. When the transfer turnover member 240 is located at the first turnover position, the fixing member 250 is a suction cup that can adsorb the material 1000 placed on the transportation mechanism 100. At this time, the material 1000 is horizontally placed, and the axis of the material 1000 extends in the vertical direction to facilitate stable transportation on the transportation mechanism 100. When the transfer turnover member 240 is located at the second turnover position, the axis of the material 1000 extends in the left-right direction, and the pouring hole on the material 1000 can extend in the vertical direction to facilitate internal pouring. The vertical direction is the up-down direction.

[0057] Since the transportation process cannot guarantee the orientation of the pouring hole, the axis of the pouring hole may not be vertical after turnover. In order to make the pouring hole vertical upward to be connected with the pouring head 320 with the opening facing downward, in some embodiments, the transfer mechanism 200 includes a fixing driving member 251 arranged on the transfer turnover member 240, and the fixing member 250 is rotatably arranged on the transfer turnover member 240 and is in transmission connection with the output end of the fixing driving member 251. The fixing member 250 rotates to rotate the material 1000 to make the pouring hole of the to-be-poured mold 1100 upward. On the one hand, the above-mentioned arrangement can make the axis of the pouring hole of the material 1000 in the vertical direction, and the pouring hole is located at the uppermost end of the material 1000. The vertically extending pouring hole facilitates pouring through the pouring hole to make the resin smoothly enter the inner cavity. Since the pouring hole is located at the uppermost end of the material 1000, the resin is not easy to overflow when filled. On the other hand, the rotation of the fixing member 250 can help the transfer mechanism 200 find the head of the adhesive tape 1200 and facilitate accurate tearing of the adhesive tape.

[0058] To facilitate the tearing of the adhesive tape, in some embodiments, the transferring mechanism 200 further comprises a transferring horizontal moving member 220, a transferring vertical moving member 230 and a vertical moving driving member 231. The transferring horizontal moving member 220 is arranged on the transferring fixed base 210. The vertical moving driving member 231 is arranged on the transferring horizontal moving member 220. The transferring vertical moving member 230 is arranged on the transferring horizontal moving member 220 in a vertical direction and is in transmission connection with the output end of the vertical moving driving member 231. The turnover driving member 241 is arranged on the transferring vertical moving member 230. The turnover driving member 240 is arranged on the transferring vertical moving member 230 in a rotating manner. The tearing assembly 400 comprises a tearing base 410 and a tearing gripper 420 arranged on the tearing base 410 and capable of clamping the adhesive tape 1200. A tearing driving member 411 is arranged on the transferring horizontal moving member 220. The tearing base 410 is arranged on the transferring horizontal moving member 220 in a sliding manner in a tearing direction N and is in transmission connection with the output end of the tearing driving member 411. The tearing direction N and the vertical direction are arranged in an acute angle. The clamping end of the tearing gripper 420 abuts against the tearing part 1300 of the material 1000. The vertical plane passing through the axis of the material 1000 is located in front of the tearing part 1300. The material 1000 is turned backward at the tearing part 1300. The tearing direction N and the vertical direction are arranged in an acute angle, i.e. the included angle a between the tearing direction N and the vertical direction is an acute angle. The tearing driving member 411 comprises a linear module. The linear module is arranged on the transferring fixed base 210. The output end of the linear module moves in a reciprocating manner in the tearing direction N and is in transmission connection with the tearing base 410.

[0059] In use, after the adhesive tape 1200 is clamped by the tearing gripper 420, the adhesive tape 1200 is torn from the to-be-poured mold 1100 to expose the pouring hole by the movement of the tearing base 410 and the rotation of the fixed member 250.

[0060] The above structure enables the fixing member 250 to realize vertical lifting, and the tear-off base 410 and the transfer lifting member 230 can be moved individually or cooperatively to meet the tear-off requirements of the material 1000 with different diameters. For example, when the diameter of the material 1000 decreases, the transfer lifting member 230 moves upward and the tear-off base 410 does not move, or the transfer lifting member 230 moves upward and the tear-off base 410 moves forward, so that the tear-off assembly 400 and the tear-off part 1300 of the material 1000 are in contact, thereby facilitating the scraping of the adhesive tape 1200. In order to facilitate the insertion of the clamping end of the tear-off clamp 420 into the gap between the adhesive tape 1200 and the to-be-poured mold 1100, the angle between the extension direction of the clamping end and the extension direction of the adhesive tape 1200 at the tear-off part 1300 is generally obtuse. When the angle between the extension direction of the clamping end and the adhesive tape 1200 is too small, for example, 90°, in the process of searching for the head of the adhesive tape 1200, after the clamping end of the tear-off clamp 420 abuts against the head of the adhesive tape 1200, in the process of continuous rotation of the material 1000, the adhesive tape 1200 is easily accumulated and damaged; when the angle is too large, for example, 180°, the clamping end of the tear-off clamp 420 cannot enter the gap between the adhesive tape 1200 and the to-be-poured mold 1100, thereby failing to scrape the adhesive tape 1200.

[0061] With the above structure, the angle between the extension direction of the clamping end and the adhesive tape 1200 can be adjusted while adapting to the material 1000 with different diameters, and through the movement of the transfer lifting member 230 and the cooperative movement of the tear-off base 410. When the diameter of the material 1000 decreases, the tear-off base 410 moves forward and the transfer lifting member 230 moves upward, so that when the tear-off clamp 420 and the material 1000 are in contact, the angle between the clamping end of the tear-off clamp 420 and the adhesive tape 1200 is adjusted to the best, thereby facilitating the scraping of the adhesive tape 1200. That is, the smaller the diameter, the smaller the distance from the point where the tear-off clamp 420 and the material 1000 are in contact to the standard vertical plane. The standard vertical plane is a vertical plane passing through the axis of the material 1000. It should be noted that the best angle of the clamping end of the tear-off clamp 420 inserted into the adhesive tape 1200 can be 100°-150°, that is, the best angle between the extension direction of the clamping end of the tear-off clamp 420 and the tangent of the material 1000 at the tear-off part 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.

[0062] In some embodiments, the tear direction N is parallel to the tangential direction of the material 1000 at the tear portion 1300, so that after the tear clamp jaw 420 clamps the adhesive tape 1200, the tear base 410 can be directly moved to avoid interference between the tear clamp jaw 420 and the to-be-poured mold 1100. In other words, the tear direction N is tangent to the material 1000 at the tear portion 1300, or in other words, in the case where the clamping end of the tear clamp jaw 420 abuts the tear portion 1300 of the material 1000, the moving path of the clamping end of the tear clamp jaw 420 and the radius of the to-be-poured mold 1100 passing through the tear portion 1300 are perpendicular when the tear base 410 is moved to avoid scratching the to-be-poured mold 1100.

[0063] In some different product models, the axis of the pouring hole and the axis of the tape-pouring mold are not perpendicular. Due to the presence of the transfer flipper 240, after the adhesive tape 1200 is torn, the transfer flipper 240 can be rotated by a certain angle, so that the axis of the pouring hole extends in the vertical direction to facilitate pouring.

[0064] Generally, the outer periphery of the to-be-poured mold 1100 is circular, but due to the limitation of the manufacturing process, the outer periphery of the to-be-poured mold 1100 has a protruding structure, i.e., a non-circular structure. In order to avoid interference of the protruding structure with the tear clamp jaw 420, in combination with Figs. 1 and 2, in some embodiments, the protruding structure of the to-be-poured mold 1100 is a protruding structure 1110. Figure 5 and Figure 6 As shown in Figs. 1 and 2, in some embodiments, the tear clamp jaw 420 includes a fixed clamp jaw 421, a tear spring 425, and a movable clamp jaw 422. The fixed clamp jaw 421 is hinged to the tear base 410 and can rotate between an initial position and a retreat position. When the fixed clamp jaw 421 is in the initial position, the clamping end of the fixed clamp jaw 421 abuts the tear portion 1300. The clamping end of the fixed clamp jaw 421 can move backward to rotate the fixed clamp jaw 421 from the initial position to the retreat position. The tear spring 425 is used to apply an elastic force to the fixed clamp jaw 421 to stop it in the initial position. The movable clamp jaw 422 can move closer to or away from the fixed clamp jaw 421.

[0065] With the above structure, during the rotation of the material 1000, the fixed clamp jaw 421 and the tear portion 1300 of the outer periphery of the material 1000 are in sliding fit, until the adhesive tape 1200 is scooped up, the movable clamp jaw 422 approaches the fixed clamp jaw 421 to clamp the adhesive tape 1200. During the rotation of the material 1000, when the protruding structure of the outer periphery of the to-be-poured mold 1100 rotates to abut the fixed clamp jaw 421, the fixed clamp jaw 421 is flipped backward to avoid interference with the protruding structure. When the protruding structure rotates away, the fixed clamp jaw 421 returns to the initial position under the action of the tear spring 425.

[0066] In addition, under the action of the tearing elastic member 425, the fixed clamping jaw 421 can always abut against the tearing part 1300 of the material 1000, avoiding missing the head of the adhesive tape 1200. Finally, after tearing the adhesive tape 1200, the elastic force is always applied to the adhesive tape 1200, which can first straighten the adhesive tape 1200, avoiding shielding the pouring hole, and secondly, avoiding applying too large force to the adhesive tape 1200, which can cause the adhesive tape 1200 to be pulled off or the material 1000 to be separated from the fixing member 250, and the adhesive tape 1200 to be separated from between the fixed clamping jaw 421 and the movable clamping jaw 422.

[0067] In combination Figure 8 As shown, the fixed clamping jaw 421 includes a jaw body 4211 and a shovel part 4212 connected at an angle, the angle A1 between the jaw body 4211 and the vertical direction is smaller than the angle A2 between the shovel part 4212 and the vertical direction, and the jaw body 4211 and the shovel part 4212 are connected through a circular arc. Optionally, 0 < A1 < A2. The angle between the shovel part 4212 and the vertical direction is between 70° and 85°.

[0068] Generally, in order to improve the success rate of tearing, the movable clamping jaw 422 is detected before approaching the fixed clamping jaw 421, and after the adhesive tape 1200 is scooped up by the fixed clamping jaw 421, the movable clamping jaw 422 acts to clamp the adhesive tape 1200. However, in actual operation, after the adhesive tape 1200 is scooped up, a curling structure is formed, and during the approach of the movable clamping jaw 422 to the fixed clamping jaw 421, the adhesive tape 1200 will be bounced out. However, after the movable clamping jaw 422 approaches the fixed clamping jaw 421, the detection component cannot detect again, resulting in invalid action in the subsequent tearing process, and thus causing the resin to be poured outside during subsequent pouring, causing pollution.

[0069] In combination Figures 5 to 7 To solve this problem, in some embodiments, the tearing clamping jaw 420 further includes a detection member 430, the fixed clamping jaw 421 is provided with a first detection hole 4213, the movable clamping jaw 422 is provided with a second detection hole 4221, and the light of the detection member 430 can pass through the first detection hole 4213. When the movable clamping jaw 422 approaches the fixed clamping jaw 421, the first detection hole 4213 and the second detection hole 4221 at least partially overlap in the direction of the light emitted by the detection member 430, and the light of the detection member 430 can pass through the first detection hole 4213 and the second detection hole 4221. When the fixed clamping jaw 421 scoops up the adhesive tape 1200, the adhesive tape 1200 will shield the first detection hole 4213, thereby shielding the light emitted by the detection member 430, so that part of the light passes through the adhesive tape 1200 and part of the light is reflected, thereby judging that the adhesive tape 1200 has been scooped up. At this time, the movable clamping jaw 422 approaches the fixed clamping jaw 421 to clamp the adhesive tape 1200.

[0070] Due to the presence of the second detection hole 4221, after the adhesive tape 1200 is clamped, light can still partially pass through the adhesive tape 1200 and partially reflect, so that it can be determined that the adhesive tape 1200 is successfully clamped. If the adhesive tape 1200 is ejected during clamping, light directly passes through the first detection hole 4213 and the second detection hole 4221 and cannot pass through the adhesive tape 1200, so that there is no amount of reflection, it can be determined that the clamping of the adhesive tape 1200 fails, and the movement can be stopped in time and the staff can be notified or the clamping can be performed again.

[0071] In use, even if the second detection hole 4221 exists, after the adhesive tape 1200 is ejected, if the adhesive tape 1200 is attached to the side of the movable clamping jaw 422 away from the fixed clamping jaw 421, light can still partially pass through the adhesive tape 1200 and partially reflect, so that the detection piece 430 still has the possibility of misjudgment. To solve the above problem, in combination with Figure 9 As shown, further, the adhesive tape clamping jaw 420 further comprises an intercepting piece 423, the intercepting piece 423 is arranged on the movable clamping jaw 422 and has an intercepting portion 4231 in the form of a plate, when the movable clamping jaw 422 is close to the fixed clamping jaw 421, the length of the adhesive tape 1200 clamped between the movable clamping jaw 422 and the fixed clamping jaw 421 is L1, the length of the intercepting portion 4231 is L2, and L2≥L1. Wherein, the extending direction of the intercepting portion 4231 is perpendicular to the movable clamping surface of the movable clamping jaw 422.

[0072] The above arrangement makes it possible to avoid the adhesive tape 1200 being attached to the side of the movable clamping jaw 422 away from the fixed clamping jaw 421 even if the adhesive tape 1200 is ejected and not clamped, so that light can directly pass through the second detection hole 4221, so that it can be determined that the clamping fails, and the movement can be stopped in time and the staff can be notified or the clamping can be performed again.

[0073] The arrangement of the intercepting portion 4231 makes the intercepting portion 4231 located outside the extending direction of the first detection hole 4213 when the movable clamping jaw 422 is away from the fixed clamping jaw 421, and does not block the light of the detection piece 430.

[0074] The movable clamping jaw 422 is hinged to the fixed clamping jaw 421, and when the movable clamping jaw 422 is opened relative to the fixed clamping jaw 421, the projection of the movable clamping jaw 422 is located outside the projection profile of the first detection hole 4213 in the extension direction of the first detection hole 4213, and the light of the detection member 430 is not blocked.

[0075] In combination Figure 10 As shown in the drawings, in some embodiments, the tear-off assembly 400 comprises a stop driving member 440 and a stop member 441, the stop driving member 440 is arranged on the transfer transverse moving member 220, the stop member 441 is arranged on the output end of the stop driving member 440 and can move along the stop direction between the stop position and the yielding position, the stop member 441 in the stop position is located below the tear-off clamping jaw 420 and can press against the adhesive tape 1200 on the to-be-poured mold 1100, and the stop member 441 in the yielding position is located outside the material 1000 and has a gap with the material 1000. With the arrangement of the stop member 441, when the tear-off assembly 400 tears off the adhesive tape 1200, the connection between the adhesive tape 1200 and the to-be-poured mold 1100 can be pressed, so that the area of the torn-off adhesive tape 1200 is as small as possible, and the accumulation of too much torn-off adhesive tape 1200 is avoided to cause interference to the pouring hole in the pouring process. The stop direction is parallel to the tear-off direction N.

[0076] In addition, during the reverse rotation of the fixed member 250, the stop member 441 can also paste the adhesive tape 1200 on the side wall of the to-be-poured mold 1100 to block the pouring hole.

[0077] In order to facilitate detection, the transfer mechanism 200 further comprises a ring-shaped light source 260 arranged on the transfer overturning member 240, which is used to provide a light source to the circumferential side of the to-be-poured mold 1100 to facilitate finding the root and head of the adhesive tape 1200. In the axial direction of the to-be-poured mold 1100, the ring-shaped light source 260 is located outside the outer periphery of the to-be-poured mold 1100. In use, when the axis of the to-be-poured mold 1100 extends in the left-right direction, i.e. after the transfer overturning member 240 is overturned, the ring-shaped light source 260 is turned on, and after the adhesive tape 1200 is torn off, the ring-shaped light source 260 is turned off. With the above arrangement, the ring-shaped light source 260 is turned on before the tearing-off action starts, which reduces energy waste.

[0078] In combinationFigure 2 As shown, in some embodiments, the transfer mechanism 200 further comprises a horizontal movement driving member 221 arranged on the transfer fixing seat 210, and the transfer horizontal movement member 220 is slidingly arranged on the transfer fixing seat 210 and in transmission connection with the output end of the horizontal movement driving member 221. During the movement of the transfer horizontal movement member 220, the adhesive tape 1200 on the mold 1100 to be poured is torn by the adhesive tape tearing assembly 400. Since the pouring mechanism 300 is located on the right side of the conveying mechanism 100, the transfer horizontal movement member 220 is slidingly arranged on the transfer fixing seat 210 in the left-right direction. The above arrangement makes the material 1000 picked up by the fixing member 250, and then the transfer lifting member 230 is lifted, and then the transfer overturning member 240 is overturned to adjust the axis of the material 1000 from the vertical direction to the left-right direction. Next, the adhesive tape 1200 on the mold 1100 to be poured can be torn during the movement of the transfer horizontal movement member 220, so that the transfer of the material 1000 and the adhesive tape tearing process are partially overlapped, and the overall pouring efficiency is improved.

[0079] In combination Figure 1 And Figure 12 As shown, the conveying mechanism 100 comprises a first flow line 110, a second flow line 120 and a transfer assembly 130. The first flow line 110 is used to move the material 1000 from a first upper feeding position to a first lower feeding position. The transfer assembly 130 is used to transfer the material 1000 at the first lower feeding position to a transfer position. The second flow line 120 is used to transfer the pouring member from a second upper feeding position to a second lower feeding position. The transfer mechanism 200 can pick up the material 1000 from the transfer position and transfer the pouring member to the second upper feeding position. The transfer assembly 130 comprises a transfer seat 131 and a double-head pneumatic cylinder 132 arranged below the transfer seat 131. The two output ends of the double-head pneumatic cylinder 132 are each provided with two positioning members 133. The four positioning members 133 extend in the vertical direction and are located around the transfer seat 131. The two output ends of the double-head pneumatic cylinder 132 are telescopic to make the four positioning members 133 approach or move away from each other. When the four positioning members 133 approach each other, the material 1000 on the transfer seat 131 can be positioned to the transfer position. The transfer assembly 130 further comprises a transfer bracket 134 and a transfer member 135. The transfer bracket 134 is arranged between the first flow line 110 and the second flow line 120. The transfer member 135 is slidingly arranged on the transfer bracket 134 in the left-right direction and can be transferred between the first flow line 110 and the transfer seat 131 to transfer the material 1000 on the first flow line 110 to the transfer seat 131.

[0080] The transfer member 135 includes a transfer connecting portion 1351 and a transfer blocking portion 1353 and a transfer poking portion 1352 arranged on the transfer connecting portion 1351. The transfer blocking portion 1353 is used to stop the material 1000 on the first flow line 110, and the transfer poking portion 1352 is used to transfer the material 1000 from the first flow line 110 to the transfer seat 131 when the transfer member 135 moves to the right.

[0081] In order to adapt to different diameters of the material 1000, in some embodiments, the pouring mechanism 300 includes a pouring support 310, wherein the pouring head 320 is arranged on the pouring support 310 in a vertical direction.

[0082] In combination with Figure 1 and Figure 11 As shown in the figure, the pouring mechanism 300 further includes an illuminating member 330 and an identifying member 340. The identifying member 340 is arranged on the pouring support 310 in a vertical direction and is used to identify the root of the adhesive tape 1200. The illuminating member 330 is movably arranged on the pouring support 310 and is used to illuminate the material 1000. During the movement of the transfer mechanism 200 carrying the to-be-poured mold 1100 to the right, after the identifying member 340 identifies the root of the adhesive tape 1200, the to-be-poured mold 1100 continues to move, so that the pouring hole located in front of the root of the adhesive tape 1200 is directly below the pouring head 320. The pouring driving member 321 is arranged on the pouring support 310, the output end of the pouring driving member 321 can move in a vertical direction, and is in transmission connection with the pouring head 320 and the identifying member 340. The illuminating driving member is arranged on the pouring support 310, and the illuminating member 330 is arranged on the output end of the illuminating driving member. The illuminating driving member is used to drive the illuminating member 330 to move close to or away from the pouring head 320, so as to adapt to different diameters of the to-be-poured mold 1100 and to avoid the to-be-poured mold 1100 when it moves to the pouring position. This kind of arrangement can adapt to the upward movement of the pouring hole by moving the pouring head 320 upward when the diameter of the material 1000 increases, so as to adapt to different diameters of the material 1000.

[0083] The pouring mechanism 300 further includes a flow rate control member 322 arranged on the pouring support 310 and used to control the flow rate of the pouring head 320. It should be noted that the method for controlling the flow rate of the pouring head 320 by the flow rate control member 322 is well known to those skilled in the art, and therefore will not be described in detail here.

[0084] In some embodiments, the pouring mechanism 300 further includes a camera 350 used to take pictures of the to-be-poured mold 1100 and the pouring head 320 during pouring, so as to analyze whether the position of the to-be-poured mold 1100 is accurate. The camera 350 is located on the right side of the pouring head 320 and is mainly used to judge the distance between the pouring head 320 and the pouring hole in the left-right direction.

[0085] In some embodiments, the transfer mechanism 200 and the pouring mechanism 300 are each provided with a plurality of transfer mechanisms 200 and a plurality of pouring mechanisms 300, and each of the plurality of transfer mechanisms 200 and the plurality of pouring mechanisms 300 are arranged along the transmission direction of the transmission mechanism 100. The above arrangement enables the plurality of transfer mechanisms 200 and the plurality of pouring mechanisms 300 to cooperate to simultaneously complete the pouring work of a plurality of molds 1100 to be poured, thereby improving the pouring efficiency.

[0086] The embodiment also provides a lens pouring method applied to the lens pouring device, and the lens pouring method comprises the following steps:

[0087] S100, placing the material 1000 on the transmission mechanism 100.

[0088] S200, picking up the material 1000 on the transmission mechanism 100 by the fixing member 250 of the transfer mechanism 200, and tearing the adhesive tape 1200 on the mold 1100 to be poured connected with the fixing member 250 by the adhesive tape tearing assembly 400 of the transfer mechanism 200 to expose the pouring hole.

[0089] S300, transferring the material 1000 to the pouring position.

[0090] S400, pouring the mold 1100 to be poured by the pouring mechanism 300 to form a pouring piece.

[0091] By means of the above method, the material 1000 does not need to be positioned from the film tearing to the pouring process after being picked up by the fixing member 250, the pouring efficiency is improved, and the equipment cost is reduced.

[0092] In the process of transferring the material 1000 by the transfer mechanism 200, the adhesive tape 1200 on the mold 1100 to be poured is torn by the adhesive tape tearing assembly 400 to expose the pouring hole, the transferring of the material 1000 and the adhesive tape tearing process are partially overlapped, and the pouring efficiency is further improved.
