Description

TECHNICAL FIELD

[0001] The utility model belongs to lens adhesive tape equipment technical field, especially be related to full -automatic tape machine B mould jacking mechanism. BACKGROUND

[0002] In the lens production line, the tape machine is used for bonding the A mould and the B mould of the lens through the adhesive tape, and a cavity for pouring lens forming liquid is formed between the A mould and the B mould of the lens.

[0003] The Chinese patent document with the publication number CN107972214A discloses a multifunctional full-automatic tape machine, which comprises a left molding mechanism and a right molding mechanism. A fixed sheet feeding mechanism is arranged between the two molding mechanisms. An active positioning mechanism is arranged at the rear side of the sheet feeding mechanism. The positioning mechanism is installed on a guide rail and connected with a lead screw. The positioning mechanism is moved to the left or right molding mechanism for molding according to the rotation of the lead screw. In the application, the B mould is lifted to the B mould positioning arm by the B mould feeding cylinder. Since the B mould positioning arm clamps the B mould through four positioning columns, it is possible that three positioning columns clamp the B mould, and the other positioning column cannot completely adhere to the B mould. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at solving the above technical problem, and provides a full-automatic tape machine B mould jacking mechanism, which jacks up the two-section lens B mould, so that the B mould can completely adhere to the four positioning columns after being jacked up, thereby improving the accuracy of the lens B mould positioning.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The full-automatic tape machine B mould jacking mechanism comprises a jacking seat, a deviation rectifying head, a double-stroke cylinder, a guide rod and a mounting frame. The upper end and the lower end of the double-stroke cylinder are slidably connected to the mounting frame in the up-down direction. The guide rod is fixedly connected to the lower end of the double-stroke cylinder. The deviation rectifying head is rotatably connected to the top of the guide rod. The jacking seat is sleeved on the top of the guide rod and tightly matches with the guide rod.

[0007] As a preferred technical scheme, the full-automatic tape machine B mould jacking mechanism further comprises a jacking seat base. The jacking seat base is fixedly installed on the top of the mounting frame. The guide rod is sleeved in the jacking seat base and rotatably connected with the jacking seat base.

[0008] As a preferred technical scheme, the full-automatic tape machine B mould jacking mechanism further comprises a spring. The spring is sleeved on the guide rod and located between the jacking seat base and the jacking seat.

[0009] As a preferred technical solution, the top of the correction head is spherical.

[0010] As a preferred technical solution, the lower part of the lifting seat is provided with a limiting step.

[0011] By adopting the above technical solution, this utility model has the following advantages:

[0012] This invention relates to a B-die lifting mechanism for a fully automatic tape machine. The mechanism is used for lifting and positioning the B-die in a fully automatic tape machine. A double-stroke cylinder drives a guide rod to lift upwards until the lifting seat contacts the lower surface of the B-die. The double-stroke cylinder then drives the guide rod to continue lifting upwards, with the top of the correction head extending beyond the lifting seat. After the B-die is positioned, the double-stroke cylinder drives the guide rod to descend, the lifting seat resets, and the correction head retracts into the lifting seat. This invention improves the positioning accuracy of the B-die. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-2 As shown, the B-mold lifting mechanism of the fully automatic tape machine includes a lifting seat 1, a correction head 2, a double-stroke cylinder 3, a lifting seat base 4, a guide rod 5, a mounting bracket 6, and a spring 7.

[0017] The upper and lower ends of the double-stroke cylinder 3 are slidably connected to the mounting bracket 6 in the vertical direction. The guide rod 6 is fixedly connected to the lower end of the double-stroke cylinder 3.

[0018] The lifting base 4 is fixedly mounted on the top of the mounting bracket 6. The guide rod 5 is fitted into the lifting base 4, and the guide rod 5 is rotatably connected to the lifting base 4 through a set of bearings. The guide rod 5 can rotate and move up and down relative to the lifting base 4.

[0019] The spring 7 is fitted onto the guide rod 5 and is located between the lifting seat base 4 and the lifting seat 1.

[0020] The deviation rectifying head 2 is rotationally connected at the top of the guide rod 5. The top of the deviation rectifying head 2 is in spherical shape.

[0021] The jacking seat 1 is sleeved at the top of the guide rod 5 and is in tight fit with the guide rod 5. The jacking seat 1 can be lifted up and down along the guide rod 5. After the jacking seat 1 is lowered relative to the guide rod 5, the top of the deviation rectifying head 2 can be exposed relative to the upper surface of the jacking seat 1.

[0022] A limiting step is arranged at the lower part of the jacking seat 1. When the limiting step abuts against the bottom of the deviation rectifying head 2, the jacking seat 1 is limited by the deviation rectifying head 2 to prevent the jacking seat 1 from being separated from the guide rod 5 after continuously moving upward along the guide rod 5.

[0023] The working process of the B mold jacking mechanism of the full-automatic tape machine B is as follows:

[0024] 1. The double-stroke cylinder 3 drives the guide rod 5 to be jacked upward until the jacking seat 1 jacks the B mold to be positioned in the B mold positioning seat, which is the first stroke of the double-stroke cylinder 3.

[0025] 2. The double-stroke cylinder 3 drives the guide rod 5 to be continuously jacked upward until the jacking seat 1 jacks the B mold to be positioned on the step of the B mold positioning seat, the spring 7 is compressed, and the top of the deviation rectifying head 2 is exposed from the jacking seat 1, which is the second stroke of the double-stroke cylinder 3.

[0026] At this time, the top of the deviation rectifying head 2 abuts against the center of the concave surface of the B mold, the position of the B mold is corrected, and the outer circumferential surface of the B mold abuts against the four positioning columns at the same time.

[0027] 3. After the B mold is positioned, the double-stroke cylinder 3 drives the guide rod 5 to be lowered, the jacking seat 1 is reset under the action of the spring 7, and the deviation rectifying head 2 is retracted into the jacking seat 1.

[0028] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application.
