Description

  In particular, the present invention relates to an apparatus for calibrating a thermocompression mold for packaging contact lenses.

  When manufacturing an existing disposable contact lens, a storage container made of plastic for storing the contact lens is prepared, a plurality of storage recesses are formed in the storage container, and the contact lens and physiological saline are formed in the storage recess The aluminum sealing seal is thermocompression bonded to the storage container by a thermocompression bonding means and sealed.

  However, existing storage containers for disposable contact lenses may be displaced at the time of manufacture, and there is a problem that the thickness of the storage container becomes non-uniform due to the displacement. For this reason, when thermocompression processing is performed using a contact lens sealing device, the aluminum sealing seal cannot be firmly thermocompression bonded even if the push plate is combined with the storage container. Cannot be sealed in the storage container, and there is a risk that physiological saline may leak.

  A calibration apparatus that automatically corresponds to the vertical position and thickness non-uniformity of the thermocompression bonding mold according to the present invention has a lower seat portion and a plurality of lower pressing members installed on the lower moving plate, The lower seat portion is formed with a plurality of through holes spaced apart from each other, and the plurality of lower pressing members are installed in the through holes of the lower seat portion, and the lower pressing member includes a push column and an elastic member, The push column is installed in the through hole so as to be slidable up and down, and the elastic member is installed in the through hole so that one end contacts the push column and the other end contacts the lower moving plate. The push column is moved upward by the urging force, and the push column is moved upward by presetting the urging force of the elastic member.

  The calibration device that automatically corresponds to the vertical position and thickness non-uniformity of the thermocompression die according to the present invention is such that the push column installed below the base moves the storage container installed above the base upward. Since the lower thermocompression bonding member moves downward and thermocompression-bonds the storage container, the pressing column and the lower thermocompression bonding member sandwich the storage container from above and below, so that the storage container becomes the thermocompression bonding member. Can be pressed firmly.

  Further, since the lower pushing portion can slide up and down with respect to the lower seat portion, an appropriate pressing force can be provided according to a portion where the thickness of the storage container is different, and the elastic member moves the pushing column upward by the biasing force. Therefore, the upward pressing force from the elastic member is large for the thin portion of the storage container, and the upward pressing force from the elastic member is small for the thick portion of the storage container. Become. Accordingly, even if the thickness of the storage container is different, an appropriate pressing force can be provided, and the storage container can be firmly pressed against the thermocompression bonding member, so that errors caused by different thicknesses can be suppressed. .

The lower seat portion 44 is connected to the upper surface of the lower moving plate 31, and the through holes 45 are formed in the lower seat portion 44 at intervals. The number of the through holes 45 is the same as the number of the positioning holes 411 of the tray 41, and the positions of the through holes 45 correspond to the positions of the positioning holes 411 of the tray 41.

As shown in FIGS. 6 and 7, the plurality of lower pressing members 46 are provided on the upper surface of the lower seat portion 44 at an interval, and the number of the lower pressing members 46 matches the number of the positioning holes 411. The positions of the lower pressing members 46 correspond to the positions of the positioning holes 411.
In addition, each of the plurality of lower pressing members 46 in this embodiment is movably inserted into the positioning hole 411 of the tray 41 so as to be accommodated in the through hole 45.

  As shown in FIGS. 6, 11, and 12, a stop surface 451 is annularly provided on the upper bottom surface of the through hole 45, and a conical wall 452 is provided below the through hole 45. The conical wall 452 has a tapered shape and is formed so as to become narrower as it goes upward from the lower seat portion 44.

  The lower pressing member 46 includes a pressing column 461 and an elastic member 462. The pressing column 461 is installed in the through hole 45 so as to be slidable in the vertical direction. The elastic member 462 has an upper end abutting on the pressing column 461, and The lower end is installed in the through hole 45 so as to contact the lower moving plate 31. That is, the through hole 45 is installed between the push column 461 and the lower moving plate 31, and pushes the push column 461 upward by the elasticity of the through hole 45.

As shown in FIGS. 11 and 12, the push column 461 includes an upper rod 463 and a lower rod 464. The upper rod 463 is installed in the through hole 45 so as to be slidable in the vertical direction. When the upper rod 463 slides downward, the upper rod 463 comes into contact with the stop surface 451 and stops, so that it does not move to the conical wall 452. .
Further, since the inner diameter of the through hole 45 is larger than the outer diameter of the upper rod 463, the upper rod 463 is installed obliquely with respect to the axis L of the through hole 45 as shown in FIG. May be.

Further, an opening 465 is formed in the upper part of the upper rod 463, and a peripheral wall 466 is formed around the opening 465. The lower rod 464 has a conical shape and is installed in the through hole 45 so as to be vertically slidable so as to be positioned below the upper rod 463, and pushes the upper rod 463 upward. Since the shape of the outer peripheral wall of the lower rod 464 corresponds to the shape of the conical wall 452, the lower rod 464 is installed on the conical wall 452 of the through hole 45.
The elastic member 462 is installed between the bottom surface of the lower rod 464 and the lower moving plate 31 and pushes the lower rod 464 upward by the elastic member 462. Since the conical wall 452 and the shape of the lower rod 464 correspond to each other, the range in which the lower rod 464 moves upward can be limited, so that the elastic member 462 moves upward due to the elasticity of the push column 461. However, it does not detach from the through hole 45.

  A bolt is attached between the upper rod 463 and the lower rod 464, and the bolt fixes the upper rod 463 and the lower rod 464. Note that the fixing means is not limited to such screw means, and other technical means may be used as long as the upper rod 463 and the lower rod 464 can be fixed.

  The calibration apparatus that automatically corresponds to the non-uniformity of the vertical position and thickness of the thermocompression die according to the present invention has a non-pressed state and a pressed state. Among them, when used in a non-pressed state, as shown in FIGS. 4 and 9, the upper moving plate 21, the base 10, and the lower moving plate 31 are sequentially spaced from top to bottom. The thermocompression bonding member 42 on the bottom surface of the upper moving plate 21 and the pressing member 43 on the upper surface of the lower moving plate 31 do not contact the tray 41 on the base 10.

As shown in FIG. 13, in the above-described state, the storage container 91 for storing the contact lens is disposed in the tray 41, and is combined with the storage container 91 in correspondence with the positioning hole 411 of the tray 41. A bonded structure is formed. According to this coupling structure, the storage container 91 can be firmly positioned on the receiving tray 41.
More specifically, when the storage container 91 is formed with a plurality of recesses 92 and is disposed on the receiving tray 41, the storage container 91 is directed downward via the recess 92. In the positioning hole 411.

  Thereafter, an aluminum sealing seal is installed on the upper surface of the storage container 91, and the upper moving plate 21 is moved downward by driving the upper power unit 22 of the upper power mechanism 20 and the lower power unit 32 of the lower power mechanism 30. At the same time, the lower moving plate 31 is moved upward. According to this, the thermocompression bonding member 42 approaches the storage container 91 from above, and the push member 43 approaches the storage container 91 from below to switch the non-pressed state to the pressed state.

  As shown in FIGS. 5 and 10, when switched to the pressed state, the thermocompression bonding member 42 presses the aluminum sealing seal (not shown) of the storage container 91, and the upper pressing portion 422 corresponds to the positioning hole 411. The aluminum sealing seal is pressed against the periphery of the recess 92 of the storage container 91 and joined to the storage container 91 by thermocompression bonding. According to this, the storage container 91 containing the contact lens and the physiological saline can be sealed.

As shown in FIGS. 10, 11, and 12, when the pressing member 43 moves upward in conjunction with the lower moving plate 31, the upper rod 463 passes through the elongated hole 11 of the base 10 and becomes the positioning hole 411. When inserted, the peripheral wall 466 at the upper end of the upper rod 463 contacts the bottom surface of the storage container 91 installed inside the positioning hole 411 (that is, the peripheral edge of the bottom surface of the recess 92) to generate upward support force. To do.
At this time, since the thermocompression bonding member 42 is in contact with the upper surface of the storage container 91, the pressing member 43 presses the storage container 91 upward, and the aluminum sealing seal is firmly pressed against the storage container 91 to generate heat. Since it can join by crimping | bonding, it can seal in the storage container 91 containing the contact lens and the physiological saline.

  Furthermore, as shown in FIGS. 9 to 12, when manufacturing the tray 41, if the thickness of the tray 41 is not uniform due to insufficient processing accuracy, or if the surface of the tray 41 is inclined, The thermocompression bonding member 42 moves downward and presses the tray 41. However, a large pressing force is applied to the thick portion of the tray 41 from the thermocompression bonding member 42, and a thin portion or an inclined portion of the tray 41 is a thermocompression bonding member. Since only a small pressing force is applied from 42, the pressing force is insufficient and the bonding effect is reduced.

In order to solve the above-described problem, the pressing member 43 is moved upward by using the elastic force of the elastic member 462 and pressed, whereby different pressing forces are applied to portions where the thickness of the tray 41 is not uniform. give. That is, when the elastic member 462 presses the thick part of the tray 41, the degree of compression increases, and when the elastic member 462 presses the thin part of the tray 41, the degree of compression decreases.
According to this, the problem that the effect of thermocompression bonding in the case where the thickness in the tray 41 is not uniform or the surface is not flat can be solved. Moreover, even if the thermocompression bonding member 42 is worn out due to long-term use, the lower pressing member 46 can be used to adjust appropriately according to different thicknesses of the thermocompression bonding member 42.

  Further, a calibration device that automatically copes with the non-uniformity of the vertical position and thickness of the thermocompression die according to the present invention provides a conical outer peripheral surface of the lower rod 464 and a conical wall 452 of the through hole 45. If it exists, the extent to which the elastic member 462 pushes and moves the lower push member 46 upward is limited. According to this, it is possible to prevent the problem that the lower pressing member 46 is moved greatly upward and the storage container 91 is strongly pressed against the thermocompression bonding member 42 and melts due to excessive heating.

As shown in FIGS. 3, 5, 9, and 10, the calibration device that automatically copes with the non-uniformity in the vertical position and thickness of the thermocompression die according to the present invention includes the thermocompression bonding member 42 and By holding the storage container 91 from above and below using the pressing member 43, the storage container 91 can be firmly pressed against the thermocompression bonding member 42.
In addition, since the pressing member 43 includes the pressing column 461 and the elastic member 462, it is possible to apply different pressing forces depending on the thickness of the tray 41, so that the thickness of the tray 41 is not uniform, or Even if the surface is inclined, the degree of thermocompression bonding can be adjusted appropriately.
