SU565826A1 - Apparatus for glueing resin onto workpieces - Google Patents

Description

The invention relates to devices for applying (sticking) resin onto workpieces, namely to auxiliary devices for grinding, 3 in particular to devices for sticking resin to a workpiece of optical parts.

A device for gluing resin onto optical workpieces is known, comprising a rotary table for supplying blanks, kinematically coupled to driving an intermittent motion with an actuating motor, an electric heater, resetter and feeder unit with valve 1 located on the frame above the rotary table.

In the known device, the table associated with the intermittent motion drive alternately supplies the preheated blanks under the feeder block, after which the resin is poured onto the blanks, which the table then transfers to the diverter.

In the known device, it is not possible to obtain quality products due to the formation of a pocket at the edge of the workpiece, in which the abrasive is clogged during grinding. The formation of a pocket is due to the presence of a contact angle greater than 7G / 2, on the border of the liquid resin - glass and

loss of fluidity of the resin due to its cooling during pouring.

In addition, in the indicated device, it is difficult to remove the blank with the resin from the frame pasted on it due to the resin sticking to the onBeBej, which also degrades the quality of the sticker. In addition, when storing a batch of blanks of even one diameter, a significant number of frames are used.

The aim of the invention is to improve the quality of products.

The goal is achieved by the fact that the device is equipped with a cooled matrix installed between the power supply unit and the rotary table and the pusher located coaxially with it under the rotary table, kinematically connected with the rotary table drive. The matrix is provided with an insert made of an anti-adhesive material with respect to a resin, such as graphite.

FIG. 1 shows a kinematic diagram of the device; in fig. 2 - matrix, longitudinal section.

The proposed device comprises a turntable 1 mounted on a frame (not shown in the drawings) for feeding workpieces, kinematically coupled through a drive 2 of intermittent motion.

Executed in the form of a Maltese cross, with an executive engine 3, placed above a rotary table, a heated block feeder 4 with a valve 5, kinematically connected with the executive engine 3, a cooled matrix 6, provided with an insert, and a resetter 8 of the workpiece with resin, under the turntable 1, the pusher 9 co-axially with the matrix 6 is kinematically associated with the turntable drive by means of a gear 10 and cam I. The device is equipped with an electric heater (not shown in the drawings). The turntable 1 has slots 12 for blanks.

The device works as follows. The billets heated on the electric heater are alternately placed in the sockets 12 of the turntable D, which is intermittently transmitted from the executive motor. The blanks come under the valve 5 of the feeder 4, while the movement is transmitted to the pusher 9 through the gear 10 and the cam 11. The pusher, moving vpex, pushes the workpiece out of the socket 12 and transfers it to the matrix 6. block 4, valve 5 rises and a portion of heated resin is poured. During casting, the pusher 9 continues to move the workpiece in the matrix 6 to the design position, making the pressing of the cast resin. After the resin is poured, the pusher lowers the workpiece into the socket 12 of the turntable and moves to its original position. The table, turning, removes the workpiece with a paste on it with resin from under the valve 5, at the same time delivering the next workpiece under it. A blank with glued resin is removed from the table with a resetter. Then the cycle repeats.

The size of the resin portion is controlled by the valve lift, and the resin temperature is monitored with a thermometer and the monitor is periodically turned on and off by the heating element of the power supply unit 5. s
