DETAILED DESCRIPTION

[0031] In order to make the people in the art better understand the scheme of the present application, the technical scheme in the specific embodiment of the present application will be clearly and completely described below in combination with the drawings in the embodiment of the present application.

[0032] As Figures 1-4 shown, the present application provides an automatic tape mounting mechanism 101 of a lens mold tape winding machine, which comprises a tape seat 15, a tape feeding mechanism 19 and a tape pulling mechanism 20.

[0033] The tape seat 15 is used for mounting the tape, and the tape can be sleeved outside the tape seat 15 and be in interference fit with the tape seat 15. The tape seat 15 is rotatably connected to a tape seat 15 rotating shaft through a bearing. During the rotation of the lens mold spindle, because the tape is gradually pasted and fixed on the edge of the lens mold, the tape is pulled by the lens mold, and then the tape seat 15 rotates with the tape.

[0034] The tape feeding mechanism 19 is used to deliver the tape on the tape reel to the lens mold spindle 102. The tape feeding mechanism 19 comprises a plurality of first tape feeding wheels 1911 and a plurality of second tape feeding wheels 1912. Each first tape feeding wheel 1911 is rotationally connected to a first tape feeding mounting plate 196. Each second tape feeding wheel 1912 is rotationally connected to a second tape feeding mounting plate 197, and the second tape feeding mounting plate 197 is connected with a second tape feeding mounting plate left-right translation cylinder 195 for driving the second tape feeding mounting plate 197 to translate left and right.

[0035] The tape pulling mechanism 20 is used to pull the tape head and pull the tape head from the tape seat 15, through the tape feeding mechanism 19, to the lens mold spindle 102. The tape pulling mechanism 20 comprises two tape pulling rods 201, a tape pulling rod clamping cylinder 202, a tape pulling rod rotating cylinder 203, a tape pulling rod left-right translation module 204, and a tape pulling rod front-back translation module 205. The two tape pulling rods 201 are located above the tape feeding mechanism 19.

[0036] The tape pulling rod clamping cylinder 202 connects the two tape pulling rods 201 to drive the two tape pulling rods 201 to open or clamp. The tape pulling rod rotating cylinder 203 connects the tape pulling rod clamping cylinder 202 to drive the tape pulling rod clamping cylinder 202 to rotate. The tape pulling rod left-right translation module 204 connects the tape pulling rod rotating cylinder 203 to drive the tape pulling rod rotating cylinder 203 to translate left and right. The tape pulling rod front-back translation module 205 connects the tape pulling rod left-right translation module 204 to drive the tape pulling rod left-right translation module 204 to translate front and back.

[0037] Specifically, the lower part of the two tape pulling rods 201 is provided with a thread to increase the friction between the tape pulling rod 201 and the tape.

[0038] The automatic tape loading mechanism 101 of the above lens mold tape winding machine has the following working process:

[0039] 1. The tape is installed on the tape seat 15 and is in interference fit with the tape seat 15;

[0040] 2. The second tape feeding mounting plate left-right translation cylinder 195 drives the second tape feeding mounting plate 197 to move right to make the second tape feeding mounting plate 197 away from the first tape feeding mounting plate 196, so that a gap is formed between the plurality of first tape feeding wheels 1911 and the plurality of second tape feeding wheels 1912 for the tape pulling mechanism 20 to pull the tape head;

[0041] 3, the left-right translation module 204 drives the two rubber belt rods 201 to move left to approach the rubber belt head, the rubber belt rod clamping cylinder 202 drives the two rubber belt rods 201 to clamp the rubber belt head, and the rubber belt rod rotating cylinder 203 drives the two rubber belt rods 201 to rotate, so that the rubber belt head is deflected by a certain angle, so that the two rubber belt rods 201 are not easy to slip off when clamping and tearing the rubber belt head;

[0042] 4, the left-right translation module 204 drives the two rubber belt rods 201 to move right, and the front-rear translation module 205 drives the two rubber belt rods 201 to move backward, so that the two rubber belt rods 201 drive the rubber belt head to pass through the gap between the plurality of first rubber belt feeding wheels 1911 and the plurality of second rubber belt feeding wheels 1912, and reach the rubber belt cutting mechanism 104;

[0043] 5, the left-right translation cylinder 195 drives the second rubber belt feeding installation plate 197 to move left, so that the second rubber belt feeding installation plate 197 approaches the first rubber belt feeding installation plate 196, and the plurality of first rubber belt feeding wheels 1911 and the plurality of second rubber belt feeding wheels 1912 are respectively close to the two sides of the rubber belt and tension the rubber belt;

[0044] 6, the lens mold spindle 102 starts to rotate, and the rubber belt is uniformly wound around the outer periphery of the lens mold, and the plurality of first rubber belt feeding wheels 1911 and the plurality of second rubber belt feeding wheels 1912 rotate with the rubber belt during the transmission of the rubber belt.

[0045] Through the above setting, the rubber belt head can be automatically pulled and the rubber belt can be installed, so as to improve the working efficiency of the lens mold rubber belt winding machine 1.

[0046] As a preferred technical solution, the rubber belt feeding mechanism 19 further comprises a rubber belt suction component 192. The rubber belt suction component 192 is fixedly installed on the first rubber belt feeding installation plate 196, and the rubber belt suction component 192 is located at one end of the first rubber belt feeding installation plate 196 close to the lens mold spindle 102. The rubber belt suction component 192 is provided with a rubber belt suction plane, and a plurality of air holes 1921 are arranged on the rubber belt suction plane. The air holes 1921 are connected with a suction device, and the rubber belt suction component 192 is used for adsorbing the smooth surface of the rubber belt on the rubber belt suction plane. In the present application, the suction device is a vacuum pump or the like. The rubber belt suction component 192 can stably adsorb the smooth surface of the rubber belt by using the negative pressure generated by the suction device through the rubber belt suction plane and the connected air holes 1921. This adsorption mode ensures the position stability of the rubber belt during the rubber belt feeding process, so that the rubber belt remains flat during the transmission process and is not easy to be folded or wrinkled, thereby improving the stability of the rubber belt transmission.

[0047] It should be noted that the suction force of the suction device can be adjusted to enable the rubber belt to slip relative to the rubber belt suction plane, and to ensure that the rubber belt does not separate from the rubber belt suction plane.

[0048] As a preferred technical solution, the automatic tape mounting mechanism 101 of the lens mold tape wrapping machine further comprises a tape placing platform 12 and a tape placing platform lifting mechanism 13, a tape mounting platform 11 and a tape mounting platform lifting mechanism 16, a tape pressing piece 17 and a tape pressing piece lifting mechanism 18, and a tape pushing mechanism 14.

[0049] The tape placing platform 12 is used to place a plurality of vertically stacked tapes, and the tape placing platform lifting mechanism 13 is connected to the tape placing platform 12 to drive the tape placing platform 12 to lift, so as to ensure that the uppermost tape is in a position to be pushed. In this application, the tape placing platform lifting mechanism 13 is a lifting cylinder or the like. In this application, the tape placing platform lifting mechanism 13 is a lifting motor or the like. When the tape is placed, the tape head of the tape is biased to the right side, so as to facilitate the pulling of the tape head by the tape pulling mechanism 20.

[0050] The tape mounting platform 11 is provided with a through hole through which the tape seat 15 passes, and the tape mounting platform lifting mechanism 16 is connected to the tape mounting platform 11 to drive the tape mounting platform 11 to lift. In this application, the tape mounting platform lifting mechanism 16 is a lifting cylinder or the like.

[0051] The tape pressing piece 17 is located above the tape mounting platform 11, and the tape pressing piece lifting mechanism 18 is connected to the tape pressing piece 17 to drive the tape pressing piece 17 to lift. In this application, the tape pressing piece lifting mechanism 18 is a lifting cylinder or the like.

[0052] The tape pushing mechanism 14 is used to push the uppermost tape on the tape placing platform 12 onto the tape mounting platform 11, and the tape pushing mechanism 14 is used to push the empty tape on the tape mounting platform 11 out of the tape mounting platform 11.

[0053] The working mode of the above structure is as follows:

[0054] 1. The uppermost tape on the tape placing platform 12 is pushed onto the tape mounting platform 11 by the tape pushing mechanism 14, and the tape placing platform lifting mechanism 13 lifts the placing platform by the width of one tape each time a tape is pushed;

[0055] 2. The tape mounting platform lifting mechanism 16 drives the tape mounting platform 11 to descend, the tape seat 15 passes through the through hole on the tape mounting platform 11, and the tape pressing piece lifting mechanism 18 drives the tape pressing piece 17 to press down, so that the tape seat 15 is in interference fit with the inner hole of the tape, thereby fixing and mounting the tape on the tape seat 15;

[0056] 3. After one roll of tape is used up, the tape mounting platform lifting mechanism 16 drives the tape mounting platform 11 to rise to separate the empty tape from the tape seat 15, and the tape pushing mechanism 14 pushes the empty tape on the tape mounting platform 11 out.

[0057] Through the above arrangement, the present application realizes automatic installation of new adhesive tape on the adhesive tape seat 15 and automatic dismounting of empty adhesive tape from the adhesive tape seat 15, thereby realizing automatic replacement of adhesive tape to improve the working efficiency of the lens mold adhesive tape winding machine.

[0058] Further, the automatic adhesive tape installation mechanism 101 of the lens mold adhesive tape winding machine further comprises: an empty adhesive tape falling slide table 22, the empty adhesive tape falling slide table 22 and the adhesive tape placing platform 12 are respectively located on opposite sides of the adhesive tape installation platform 11, and the upper surface of the empty adhesive tape falling slide table 22 is arranged in an inclined manner. The empty adhesive tape on the adhesive tape installation platform 11 is pushed out to the empty adhesive tape falling slide table 22 by the adhesive tape pushing mechanism 14, and the empty adhesive tape slides off from the empty adhesive tape falling slide table 22 and falls into the empty adhesive tape collecting frame.

[0059] Still further, the adhesive tape pushing mechanism 14 comprises: a pushing block 141 and a pushing block translation air cylinder 142, the pushing block 141 is provided with a V-shaped opening close to one side of the pushed adhesive tape, and the pushing block translation air cylinder 142 is connected to the pushing block 141 to drive the pushing block 141 to translate. The V-shaped opening designed on the pushing block 141 can accurately align and fit the adhesive tape, ensuring that the adhesive tape can stably move along the direction aligned by the V-shaped opening during the pushing process. This design reduces the deviation and sliding of the adhesive tape during the pushing process, improves the accuracy of the adhesive tape pushing and the accuracy of the adhesive tape positioning.

[0060] As another preferred technical solution, the automatic adhesive tape installation mechanism 101 of the lens mold adhesive tape winding machine further comprises: an adhesive tape placing platform 12, a mechanical claw and a mechanical claw driving mechanism, a mechanical claw translation mechanism and a mechanical claw lifting mechanism.

[0061] The adhesive tape placing platform 12 is used for placing a plurality of adhesive tapes. The mechanical claw is located above the adhesive tape placing platform 12 and the adhesive tape seat 15, and is used for grabbing or placing down the adhesive tape. The mechanical claw driving mechanism is connected to the mechanical claw to drive the mechanical claw to clamp or open. The mechanical claw translation mechanism is connected to the mechanical claw to drive the mechanical claw to translate. The mechanical claw lifting mechanism is connected to the mechanical claw to drive the mechanical claw to lift.

[0062] The working mode of the above structure is as follows:

[0063] 1. The new adhesive tape on the adhesive tape placing platform 12 is clamped by the mechanical claw;

[0064] 2. The mechanical claw translation mechanism drives the mechanical claw to translate to above the adhesive tape installation platform 11, and the mechanical claw lifting mechanism drives the mechanical claw to descend, so that the adhesive tape seat 15 is in interference fit with the inner hole of the adhesive tape, thereby enabling the adhesive tape to be fixedly installed on the adhesive tape seat 15;

[0065] 3. After one roll of adhesive tape is used up, the mechanical claw clamps the empty adhesive tape, so that the empty adhesive tape is separated from the adhesive tape seat 15.

[0066] Through the above arrangement, the application realizes automatic installation of new adhesive tape on the adhesive tape seat 15 and automatic dismounting of empty adhesive tape from the adhesive tape seat 15, thereby realizing automatic replacement of the adhesive tape to improve the working efficiency of the lens mold adhesive tape winding machine.

[0067] As a preferred technical solution, the adhesive tape suction component 192 is provided with an adhesive tape abutting wheel 193 close to one end of the lens mold spindle. The adhesive tape abutting wheel 193 abuts the adhesive tape against the outer periphery of the lens mold, so that when the lens mold spindle rotates, the adhesive tape is uniformly wound around the outer periphery of the lens mold.

[0068] As a preferred technical solution, the adhesive tape feeding mechanism 19 further comprises a first adhesive tape feeding mounting plate front and rear translation air cylinder 194 connected to the first adhesive tape feeding mounting plate 196 to drive the first adhesive tape feeding mounting plate 196 to translate forward and backward. The first adhesive tape feeding mounting plate front and rear translation air cylinder 194 drives the first adhesive tape feeding mounting plate 196 to move towards the direction close to the lens mold spindle, and the adhesive tape abutting wheel 193 abuts the adhesive tape against the outer periphery of the lens mold, so that when the lens mold spindle rotates, the adhesive tape is tightly attached to the outer periphery of the lens mold.

[0069] As a preferred technical solution, the adhesive tape pulling mechanism 20 further comprises a limiting abutment 207 fixedly arranged above one end of the first adhesive tape feeding mounting plate 196 close to the lens mold spindle 102. The adhesive tape pulling rod left and right translation module 204 drives the adhesive tape pulling rod 201 and the clamped adhesive tape head to translate towards the lens mold spindle 102 until the adhesive tape pulling rod left and right translation module 204 abuts against the limiting abutment 207. The limiting abutment 207 is used to constrain the stroke of the left displacement of the adhesive tape pulling rod 201, so as to prevent the adhesive tape pulling rod 201 from colliding with the adhesive tape cutting mechanism 104, the lens mold, etc., thereby preventing damage to the adhesive tape cutting mechanism 104 and the lens mold.

[0070] As a preferred technical solution, the adhesive tape pulling mechanism 20 further comprises a plurality of adhesive tape pressing wheels 198, each of which is rotationally connected to the second adhesive tape feeding mounting plate 197. The adhesive tape pressing wheels 198 are used to abut the adhesive tape against the adhesive tape suction plane, so as to keep the adhesive tape stable during transmission.

[0071] As Figures 5-8As shown, the present application also provides a lens mold tape winding machine 1, which comprises the automatic tape winding mechanism 101, the lens mold spindle 102, the lens mold moving mechanism 103 and the tape cutting mechanism 104 of the lens mold tape winding machine 1 described above.

The lens mold moving mechanism 103 comprises the lens mold clamping jaw 1031 and the lens mold clamping jaw moving mechanism 1032 which is connected to the lens mold clamping jaw 1031 to drive the lens mold clamping jaw 1031 to move, and the lens mold clamping jaw 1031 is used to move the lens mold to the lens mold spindle 102. The tape cutting mechanism 104 comprises the tape cutting tool 1041 and the tape cutting tool driving mechanism 1042 which is connected to the tape cutting tool 1041 to drive the tape cutting tool 1041 to cut the tape.

[0072] The structure of the upper suction cup assembly 1021 and the lower suction cup assembly 2022 of the present application can refer to the "upper fixing device" and "lower fixing device" in the Chinese patent document "Lens Full-automatic Anti-eccentric Tape Molding Machine" with publication number CN103264461B, so the structure of the upper suction cup assembly and the lower suction cup assembly will not be described here.

[0073] The structure of the lens mold moving mechanism 103 of the present application can refer to the "central parallel clamping block system" in the Chinese patent document "Lens Full-automatic Anti-eccentric Tape Molding Machine" with publication number CN103264461B, so the structure of the lens mold moving mechanism 103 will not be described here.

[0075] The lens mold tape winding machine 1 described above works as follows:

[0076] 1. The tape on the uppermost end of the tape placement platform 12 is pushed to the tape mounting platform 11 by the tape pushing mechanism 14, and the tape placement platform lifting mechanism 13 lifts the placement platform upward by the width of one tape for each tape pushed;

[0077] 2. The tape mounting platform lifting mechanism 16 drives the tape mounting platform 11 to descend, the tape seat 15 passes through the through hole on the tape mounting platform 11, and the tape pressing piece lifting mechanism 18 drives the tape pressing piece 17 to press downward, so that the tape seat 15 is in interference fit with the inner hole of the tape, thereby fixing and mounting the tape on the tape seat 15;

[0078] 3. The second adhesive tape feeding mounting plate left-right translation cylinder 195 drives the second adhesive tape feeding mounting plate 197 to move right, so that the second adhesive tape feeding mounting plate 197 moves away from the first adhesive tape feeding mounting plate 196, thereby forming a gap between the first adhesive tape feeding wheels 1911 and the second adhesive tape feeding wheels 1912 for the adhesive tape pulling mechanism 20 to pull the adhesive tape head;
