The sliding block 270 is connected to the bottom of the positioning block 250, and is slidably disposed on the sliding rail 280.

The bearings, the motor 240 and the slide rail 280 connected to two ends of the bi-directional screw 210 are all fixed on the support frame. In the present embodiment, the linear driving mechanism 2 is not limited to this, and a crank link mechanism, a cam mechanism, or a cylinder mechanism may be used.

The buffer component 3 is arranged at the two ends of the stroke of the clamping plate connecting piece, and adopts buffer rubber which is arranged on the supporting frame through an L-shaped bracket and a screw.

During the use, between the portable cover 4 is carried to two splint 1 to the belt feeder, motor 240 starts, drives bi-directional lead screw 210 through shaft coupling 230 and rotates, and two lead screw slider 220 are driven simultaneously to bi-directional lead screw 210 this moment, and two lead screw slider 220 drive two splint 1 each other to be close to through the splint connecting piece to press from both sides portable cover 4 and get, press from both sides tight back and can carry out injecting glue or repair coating work.

In this process, four cushion rubbers provide a limit and cushion for the cleat 1. Specific: when the clamping plates 1 are close to each other and clamp the easy-to-draw cover 4, the two buffer rubbers on the inner side provide limit and buffer for the clamping plates 1; similarly, when the clamping plates 1 are at the furthest distance from each other, the two buffer rubbers on the outer side provide limit and buffer for the clamping plates 1.

The whole device is a single-channel quick positioning and clamping device, is suitable for positioning and clamping work of the easy-to-open cover 4 of a single output channel, has a simple structure, is convenient to assemble and maintain, and can be independently debugged.

Referring to fig. 5-7, the clamping plate 1 includes two parts, namely a fixed end 110 and a clamping end 120, wherein one fixed end 110 is provided, at least one clamping end 120 is provided, and in this embodiment, two clamping ends 120 connected to each fixed end 110 are provided and correspond to two corners of the square cover. The fixed end 110 is connected with the linear driving mechanism 2, specifically, is fixedly connected with the mounting block 260 by a screw, one end of the clamping end 120 is rotatably connected with the end of the fixed end 110, the other end extends and is lapped on the upper surface of the conveying mechanism 5, and the clamping end 120 can be rotatably connected with the fixed end 110 by adopting a hinge key.

Because the belt of the belt conveyor can be loosened and jumped for a long time, the upper surface of the belt can move downwards, and the easy-to-pull cover 4 can also move downwards along with the belt. For this case, if the clamping end 120 is in a fixed state, the clamping end 120 may not be smoothly inserted between the easy-to-open cover 4 and the belt, which may cause the easy-to-open cover 4 to be unable to be positioned and clamped, and may even cause the easy-to-open cover 4 to be damaged. Therefore, the clamping end 120 is provided with a rotatable structure, and one end of the clamping end 120 can be lapped on the belt under the influence of self gravity no matter whether the belt and the easy-to-draw cover 4 move downwards or not, namely, the gap position between one end of the clamping end 120 and the belt and the easy-to-draw cover 4 is kept consistent; when the linear driving mechanism 2 drives the clamping plate 1 to approach the easy-to-pull cover 4, the clamping end 120 can quickly and smoothly enter a gap between the easy-to-pull cover 4 and the belt.

This rotational design of the gripping end 120 may also serve a positive function if the belt height is slightly offset during installation of the device.

Of course, the whole scheme is only suitable for the situation that the belt height deviation is not large, and the situation is generally difficult to find by naked eyes, so that the loss caused by the belt height deviation can be remedied; when the deviation of the height and the position of the belt is large, the belt conveyor needs to be adjusted.

The clamping end 120 is provided with an abutting surface 121 near one end of the easy-open cover 4, the abutting surface 121 abuts against the outer side surface of the easy-open cover 4 in a clamping state, the abutting surface 121 comprises a round angle notch, the round angle notch is attached to a round angle of the square cover, and when the clamping end 120 clamps the square cover, the round angle notch is clamped with the round angle edge of the square cover, so that the square cover is positioned.

When the clamping end 120 is close to the easy-open cover 4, the lifting inclined surface 122 can be inserted between the easy-open cover 4 and a belt of the belt conveyor, and in the continuous insertion process, the easy-open cover 4 can gradually slide and rise to the top end of the inclined surface along the lifting inclined surface 122 until being attached to the abutting surface 121, at the moment, the easy-open cover 4 is clamped by the clamping plate 1, and the lifted easy-open cover 4 can not interfere with a glue gun of the glue injection machine, so that glue injection and glue filling can be smoothly completed.

When the belt does not move downwards, the upper surfaces of the clamping end 120 and the fixed end 110 are arranged in a coplanar manner, namely, the clamping end 120 is in a horizontal state, and a gap is arranged between the clamping end 120 and the conveying mechanism 5 in the horizontal state, so that the belt can be prevented from being worn, and the gap is arranged according to the size of the edge round angle of the easy-to-open cover 4.

The lower surface of the gripping end 120 is embedded with a ball 123, when the two clamping plates 1 are at the maximum distance travel, the ball 123 is still lapped on the belt, and the ball 123 rolls on the upper surface of the conveying mechanism 5. Because the clamping end 120 is lapped on the belt, in order to reduce the abrasion of the clamping end 120 to the belt, the ball 123 is arranged on the clamping end 120, so that the ball 123 can roll on the belt in the belt conveying process and the clamping plate 1 horizontal clamping process, the friction force is reduced, and the belt can be prevented from being severely abraded.

In addition, when the belt moves downwards, the upper surfaces of the clamping end 120 and the fixed end 110 are not coplanar any more, the clamping end 120 is in an inclined state, and the height position of the belt can be checked at the moment.
