Description

Multi-station pouring equipment for lens mold

Technical Field

The invention belongs to the field of lens production equipment, and particularly relates to multi-station pouring equipment for an eyeglass mold.

Background

The lens mould comprises a mould A, a mould B and an adhesive tape, wherein a mould cavity is arranged between the mould A and the mould B, and one end of the adhesive tape is used as a root to be bonded with the mould A and the mould B, and then a circle of adhesive tape is bonded along the peripheral surfaces of the mould A and the mould B, so that the mould cavity is in a closed state.

In order to firmly bond the adhesive tape with the A die and the B die, the adhesive tape winds around the peripheral surface of the lens die for a circle, extends out of an excess covering part and is bonded with an upper layer of adhesive tape, the length of the excess covering part is about 70mm, so that the other end of the adhesive tape is the excess covering part, when the lens raw material needs to be poured into the die cavity, the other end of the adhesive tape is pulled along the circumferential direction of the lens die, one part of the adhesive tape is separated from the A die and the B die and is exposed out of a pouring port, the liquid lens raw material can be poured into the die cavity through a pouring tool, and therefore, the other end of the adhesive tape is also commonly called as the head part of the adhesive tape.

CN108568925A discloses a double-station casting machine, which refers to two sets of casting systems with the same structure arranged on the same workbench, each set of casting system includes a tearing mechanism for tearing off an adhesive tape and a casting component for casting cavity resin to a mold cavity, and the specific working process is as follows:

tearing the sticky tape of sealing the mechanism on to the lens mould of cladding and tearing, tearing the action and constitute by two parts actions, the first part is that the clamp of tearing sealing the mechanism gets the rebound of subassembly, the second part is the rotation of holding mechanism, the tearing of the sticky tape of great length has been accomplished in both cooperations simultaneously to form an opening that does not have the sticky tape to cover on lens mould surface, the sticky tape is torn the back, and the pouring subassembly action for the mouth of advancing of pouring subassembly corresponds with the opening, then pours.

The two pouring systems reduce the cost by sharing one feeding assembly and one discharging assembly, but the sealing tearing mechanism and the pouring assembly are integrated at the same station, so that pouring can be performed only after the adhesive tape is torn, and the adhesive tape is reset by reverse work of the sealing tearing mechanism after pouring is completed. The drawbacks of the above-mentioned devices are: when pouring and sticky tape reset, pouring and sticky tape reset occupy and tear the workspace who seals the mechanism, and when sticky tape tear seal and reset, tear and seal the mechanism and occupy the workspace of pouring subassembly again, consequently, in above-mentioned equipment, tear and seal the mechanism and occupy the resource of other side each other with the pouring subassembly, cause the pouring inefficiency.

and the pouring mechanism is positioned at the downstream of the tearing and sealing mechanism, and is used for being matched with the clamping and hanging belt mechanism which moves to the working position of the pouring mechanism so as to inject the lens raw material into the mold cavity of the spectacle lens mold through the opened pouring port.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

in this embodiment, the number of the clamping and hanging belt mechanisms a is plural, for example, the number of the clamping and hanging belt mechanisms a is matched with the number of the peripheral operating mechanisms located on the clamping and hanging belt mechanisms a, for example, in this embodiment, it is preferable that the peripheral operating mechanisms have one tearing and sealing mechanism C, two pouring mechanisms D, one adhesive tape resetting mechanism E, one feeding mechanism F and one discharging mechanism G, the number of the peripheral operating mechanisms is 6 in total, and therefore the number of the clamping and hanging belt mechanisms a is also 6.

The reason for setting like this is that because the first driving mechanism B can drive the clamping and hanging mechanism a to move, if the torn adhesive tape is fixed with the peripheral operating mechanism, and each peripheral operating mechanism is not capable of moving along with the first driving mechanism B, when the eyeglass mold H moves along with the clamping and hanging mechanism a, the adhesive tape is pulled to be separated from the eyeglass mold H. The fact that the torn adhesive tape is fixed with the clamping and hanging mechanism A is that the adhesive tape is not limited by other acting force when moving along with the clamping and hanging mechanism A.

The pneumatic clamping jaw 1 consists of an air cylinder and two clamping arms, and the air cylinder drives the two clamping arms to form reverse linear movement or opposite linear movement when working, so that opening or closing is formed. Each of the clamping arms is provided with a first mounting frame 2, so that each first mounting frame 2 is provided with at least one rotating assembly 3, and in the embodiment, each first mounting frame 2 is provided with two rotating assemblies 3.

When needs centre gripping lens mould H, the cylinder in the pneumatic clamping jaw 1 drives two arm lock and removes in opposite directions, drives two first mounting brackets 2 and removes in opposite directions, and rotating assembly 3 removes along with first mounting bracket 2 to rotating assembly 3 forms the centre gripping to the lens mould H that is located between two arm lock.

When lens mould H is rotatory, through the effect of frictional force, lens mould H transmits power for the primary shaft through first flexible cover to make the primary shaft rotate, because first flexible cover self possesses flexible effect, consequently, first flexible cover forms the centre gripping and at rotatory in-process to lens mould H, can avoid lens mould H to receive the destruction.

The hanging belt assembly comprises a first supporting assembly 4 and a first hanging belt assembly 5, the first hanging belt assembly 5 is fed or retreated towards a first opening and closing clamping unit when the first hanging belt assembly 5 is stressed, the first hanging belt assembly 5 retreats along the first opening and closing clamping unit and is abducted for the movement of a torn adhesive tape, the first hanging belt assembly 5 is fed to a specified position towards the first opening and closing clamping unit, and the first hanging belt assembly 5 provides a bonding position for the torn adhesive tape.
