Two glue pulling units are arranged on the movable frame 4 and are respectively positioned on the right sides of the two pressing pieces 61. Taking the left rubber unit that draws as an example, drawing the rubber unit to include adhesive tape clamp 42 and mount, the mount is located the front side of removing frame 4 and with remove frame 4 along horizontal direction sliding fit, is equipped with on removing frame 4 and draws the rubber driving piece, and is specific, draws the rubber driving piece in this embodiment also to adopt the cylinder, draws the rubber driving piece to pass through, draws the push rod of rubber driving piece to pass through the ring flange and be connected with the mount for drive mount horizontal slip.

The adhesive tape holder 42 is mounted at the rear of the fixing frame, and the adhesive tape holder 42 faces the pressing member 61 and is opposite to the lower limiting block 43. Taking the left cutting blade 41, the pressing member 61 and the adhesive tape holder 42 as an example, initially, the cutting blade 41 and the adhesive tape holder 42 are respectively located at the left and right sides of the pressing member 61. The adhesive tape holder 42 in this embodiment is an existing clamping jaw, and the specific structure, installation manner and movement process thereof are the same as those in the prior art, and are not described again in this embodiment.

The specific implementation process is as follows:

taking a workpiece with an octagonal cross section as an example, initially, the movable frame 4 is located above the workpiece fixture 3, the free end of the adhesive tape is pulled downwards before encapsulation, and after bypassing the lower side of the guide roller 44, the adhesive tape is pulled to the lower side of the cutter 41 from the lower side of the lower limiting block 43, and as the distance between the cutter 41 and the lower limiting block 43 is small, the part of the adhesive tape located on the right side of the lower limiting block 43 is short, and can be kept horizontal under the limiting effect of the lower limiting block 43. The side wall that the sticky tape free end was equipped with the viscose at this moment is down, leads and spacing to the sticky tape through last spacing pole 51 and spacing piece 43 down in this process.

During rubber coating, the adhesive tape driving piece drives the fixing frame to slide leftwards, after the free end of the adhesive tape is clamped by the adhesive tape clamp 42, the fixing frame is driven by the adhesive tape driving piece to slide rightwards to reset, finally, the adhesive tape driving piece is closed, and the adhesive tape is transversely stretched above the workpiece clamp 3. When the fixed frame slides leftwards, the rear end of the workpiece is manually clamped into the workpiece clamp 3, and the workpiece is positioned through the workpiece clamp 3.

Then, the movable frame 4 is driven by the second driving piece to slide downwards, so that the lower limiting block 43 slides to a position lower than the top of the workpiece, the part, close to the free end, of the adhesive tape is adhered to the top of the workpiece, meanwhile, the pressing piece 61 is pressed on the workpiece, the pressure between the adhesive tape and the workpiece is improved, and the adhering effect between the adhesive tape and the workpiece is better. And then controlling the adhesive tape clamp 42 to loosen the free end of the adhesive tape, driving the workpiece clamp 3 to rotate anticlockwise for a certain angle through the winding driving piece until the free end of the adhesive tape passes through the pressing piece 61 and is adhered to the workpiece under the action of the pressing piece 61, and controlling the winding driving piece to drive the workpiece clamp 3 to rotate clockwise to wind the adhesive tape on the workpiece.

When the winding requirement is met or is about to be met, the first driving piece drives the movable frame 4 to slide rightwards, the distance between the lower limiting block 43 and the cutting knife 41 and the side face of the workpiece is reduced, the free end, close to the lower limiting block 43, formed by cutting the adhesive tape and the free end, close to the workpiece are short, and displacement cannot occur. And finally, the linear driving piece drives the cutter 41 to slide downwards to cut off the adhesive tape, the workpiece is still in a rotating state at the moment, the free end of the adhesive tape close to the workpiece is adhered to the workpiece under the action of the pressing piece 61, meanwhile, the first driving piece controls the movable frame 4 to reset leftwards, namely, the encapsulation of one workpiece is completed, and after the workpiece is taken out of the workpiece clamp 3 and put into the next workpiece, the steps are repeated to encapsulate the next workpiece. In the process of replacing the workpiece, because the movable frame 4 slides leftwards, the distances between the cutter 41, the pressing piece 61 and the unused adhesive tape and the workpiece are increased, and the workpiece is more convenient to replace manually. Secondly, because the movable frame 4 slides rightwards when the rubber coating is finished, in the rubber coating starting process, a relatively large distance exists between structures such as the lower limit block 43 and the cutter 41 and the workpiece, when the workpiece rotates anticlockwise, the adhesive tape between the workpiece and the lower limit block 43 can be bent into a U shape, but because the space is large, and an included angle smaller than 180 degrees exists between the side face of the adhesive tape, facing the bending direction of the workpiece, and the side face of the adhesive tape, adhered with the adhesive tape, of the workpiece, the bent part of the adhesive tape cannot be adhered to the workpiece or the lower limit block 43, the phenomenon that the bent part of the adhesive tape is adhered to the workpiece and is bulged due to the fact that the bent part of the adhesive tape is not straightened is avoided, and the looseness of the adhesive tape is further avoided.

Example 2

On the basis of embodiment 1, the linear buffer in this embodiment adopts an air cylinder or a linear motor, taking the air cylinder as an example, the upper end of the guide rod is connected with a push rod of the air cylinder, when the side surface far away from the center of the workpiece rotates upwards, the air cylinder drives the mounting seat 6 to gradually slide upwards, and otherwise, the mounting seat 6 is driven to gradually slide downwards. In practical implementation, any one of the air cylinder or the linear motor and the spring in embodiment 1 can be used as a linear buffer, and at this time, the air cylinder or the linear motor is used for driving the mounting seat 6 to move vertically for a relatively large distance, and when a small protrusion or a small groove exists on the workpiece, the spring enables the pressing piece 61 to move vertically within a small range. Unlike the spring, when the encapsulation of one workpiece is completed, the mounting seat 6 in this embodiment can slide upwards for a large distance under the action of the air cylinder or the linear motor, so that the pressing member 61 moves to a position far higher than the adhesive tape holder 42, and the moving member is further prevented from obstructing the adhesive tape holder 42 from holding the adhesive tape.

The specific implementation process is as follows:

initially, the clamping member 9 faces the first jig 32 and faces the first jig 32, and under the action of the transverse pushing member, the base is away from the first jig 32, so that the clamping member 9 does not hinder the workpiece from being placed in the first jig 32.
