[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Please refer to Figures 1 to 4 The square glass bottle grabbing mechanism of this embodiment includes a double-axis cylinder 2, a pair of clamping fixing plates 4, a pair of clamping cylinders 7, a pair of V-shaped straightening blocks 5, a pair of V-shaped clamping blocks 6, and a suction cup assembly 8;

[0023] A pair of V-shaped straightening blocks 5 are symmetrically arranged on both sides of the bottle body of the square glass bottle 1 to be clamped, facing the square glass bottle 1, and are detachably hoisted on the two clamping jaws of the double-axis cylinder 2 through hoisting components. As the two clamping jaws are extended and retracted, the end surfaces of the opposite sides of the pair of V-shaped straightening blocks 5 are flat and centrally provided with a V-shaped straightening groove 51 that is concave along the extension and retraction direction of the clamping jaws. As the open state is switched to the retracted state, or through the contact of the two edge portions of the V-shaped straightening groove 51 that are on the same diagonal line as the bottle body and closer to the V-shaped straightening groove 51, the square glass bottle 1 is supported by the V-shaped surface of the V-shaped straightening groove 51 until the edge portion faces the V-shaped straightening groove 51, or through the contact of the two side outer wall surfaces that are opposite to the bottle body and closer to the V-shaped straightening block 5, the square glass bottle 1 is supported until the outer wall surface faces the end surface of the V-shaped straightening block 5;

[0024] A pair of V-shaped straightening blocks 5 are centrally provided with a guide groove 52 extending in parallel to the telescopic direction of the double-axis cylinder 2. A pair of V-shaped clamping blocks 6 installed at the execution end of a pair of clamping cylinders 7 are respectively built into the two guide grooves 52 and symmetrically arranged on both sides of the body of the square glass bottle 1 to be clamped. Facing the square glass bottle 1 after straightening, the end surface on the opposite side is flat and centrally formed with a V-shaped clamping groove 61 concave along the telescopic direction of the clamping cylinder 7. The clamping cylinder 7 drives the energy The V-shaped clamping groove 61 is exposed outside the guide groove 52 toward the direction of the square glass bottle 1 when the V-shaped clamping groove 61 is opened or closed relatively. With the switching from the opened state to the closed state, the pair of V-shaped clamping blocks 6 are clamped at the two edges of the bottle body on the same diagonal line and closer to the V-shaped straightening groove 51 through the V-shaped clamping groove 61, or are clamped at the two opposite outer wall surfaces of the bottle body and closer to the V-shaped clamping blocks 6 through the end faces.

[0027] The hoisting component comprises an adjusting pad 3 and a clamping fixing plate 4. The clamping fixing plate 4 is detachably hoisted on the clamping claw through the adjusting pad 3. A V-shaped straightening block 5 and a clamping cylinder 7 are installed on the clamping fixing plate 4.

[0028] The V-shaped straightening block 5 is made of high-density polyurethane material, which can ensure sufficient hardness of itself, and is not worn by the glass bottles and jars, and also avoids damaging the glass bottles and jars.

[0029] There are four suction cups distributed in a rectangular array, and multiple suction cups adsorb together to avoid the loss of suction force of the suction cup assembly due to air leakage in any suction cup, which affects the bottle grasping.

[0030] The V-shaped clamping block 6 is also made of polyurethane and is used to increase the friction when clamping the glass bottle, thereby increasing the pull-out resistance and avoiding damage to the bottle body.

[0031] Working Example:

[0032] Straightening before clamping:

[0033] Prepare for clamping; use a pair of V-shaped straightening blocks to drive a pair of V-shaped straightening blocks to straighten the square glass bottle between the pair of V-shaped straightening blocks; according to the initial posture of the square glass bottle, it can be divided into two situations, one is that the two edges of the square glass bottle on the same diagonal line that are closer to the V-shaped straightening blocks first contact the V-shaped straightening blocks, then at this time the pair of V-shaped straightening blocks will straighten the square glass bottle through the V-shaped surface of the V-shaped straightening groove, until the glass bottle faces the V-shaped straightening groove with the edge; the other is that the two opposite outer wall surfaces of the square glass bottle that are closer to the V-shaped straightening blocks first contact the V-shaped straightening blocks, then at this time the pair of V-shaped straightening blocks will straighten the square glass bottle with the opposite end surface, that is, the end surface facing the glass bottle, until the glass bottle faces the end surface of the V-shaped straightening blocks with the outer wall surface; at this point, the straightening is completed;

[0034] Clamping after straightening:

[0035] First, the bottom of the bottle is adsorbed by multiple suction cups of the suction cup assembly;

[0036] Secondly, a pair of V-shaped clamping blocks are used to clamp the bottle body; driven by a pair of clamping cylinders, the pair of V-shaped clamping blocks are relatively retracted toward the straightened glass bottle, or the two edges of the square glass bottle are clamped through the V-shaped clamping groove, or the opposite end faces are clamped on the outer wall of the bottle body, and together with the suction cup assembly, the glass bottle can be stably grasped.

[0037] Based on the present embodiment, the mechanism can be further assembled on an external device as a whole, and driven by the external device to complete the grabbing of square glass bottles and jars, and applied to bottle loading / unloading operations.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
