Description

Technical Field

[0001] The utility model relates to the technical field of grasping, in particular to a multi-bottle self-adaptive bottle clamping claw device. Background Art

[0002] In existing bottle gripping technology, a suction cup gripping method is usually used to grip bottles. This method has at least the following three problems: First, some bottles have caps while others do not, and the suction cup method can only grip bottles with caps; second, the diameters of bottles are not uniform, and the existing gripper can only grip bottles of a certain diameter. When multiple grippers are used, the larger diameter gripper will prevent the gripper from fully closing, resulting in a failure to clamp; third, the gripper opening distance is too large, which may make it impossible to place the bottle in the material frame. When the gripper is fully opened, it will affect the bottles placed in front.

[0003] Therefore, how to design a multi-bottle adaptive bottle clamping claw device that can adaptively clamp bottles with or without bottle caps and different diameters and adjust the distance the claws open has become an urgent problem to be solved by technicians in this field. Utility Model Content

One end of the spring is fixed to the optical axis mounting plate, and the other end is fixed to the clamping claw.

[0011] In the above technical solution, further, a bearing is provided between the clamping jaw and the optical axis, and the bearing is a linear bearing.

[0027] The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention.

[0028] A multi-bottle adaptive bottle clamping device should first be able to open the clamping jaws. Second, the clamping jaws should be able to be placed on the upper end of the bottle. Furthermore, the clamping jaws can be retracted and closed to clamp the bottle. Furthermore, the degree of clamping jaw opening can be adjusted so that when a bottle is placed in the frame, the clamping jaws open without affecting the bottles already placed in the previous row. According to a specific embodiment of the utility model, a multi-bottle adaptive bottle clamping device that meets the above requirements is designed, including:

[0029] A cylinder mounting plate 2, on which a cylinder 3 is fixed;

[0030] Two optical axis mounting plates 1 are arranged in parallel at both ends of the cylinder mounting plate 2, and the upper end of the optical axis mounting plate is fixed to the lower end of the cylinder mounting plate;

[0031] Two blocking plates 9 are arranged parallel to each other between the two optical axis mounting plates 1, and the two telescopic ends of the cylinder 3 are fixedly connected to a blocking plate 9 respectively through a connecting piece;

[0032] Several bottle clamping units, each bottle clamping unit includes at least one optical axis 4 and a clamping claw 6 composed of two clamping claws. Each optical axis 4 passes through two blocking plates 9 and is fixed at both ends to two optical axis mounting plates 1. A clamping claw and a spring 5 are respectively provided on each end of the optical axis 4. One end of the spring 5 is fixed to the optical axis mounting plate 1, and the other end is fixed to the clamping claw.

[0033] When the cylinder is closed, the blocking plate blocks the spring. At this time, the spring compression is minimal and the clamping jaws are in the minimum clamping state; when the cylinder is opened, the blocking plate pushes the clamping jaws away. At this time, the cylinder is opened to the maximum and the clamping jaws are in the fully open state, ready to clamp the bottle; when the cylinder is closed again, the blocking plate is retracted and the spring force pushes the clamping jaws tight, so that bottles of different diameters can be adaptively clamped.

[0034] Example 1

[0035] A multi-bottle adaptive bottle clamping claw device, such as Figure 1 、 2 As shown, the adaptive bottle clamping claw device described in this example includes two optical axis mounting plates 1, two cylinder mounting plates 2, a cylinder 3, ten optical axes 4, twenty springs 5, five clamping claws 6, twenty linear bearings, and two blocking plates 9; in this example, there are a total of 5 groups of gripping mechanisms, namely, 5 bottle clamping units.

[0036] In this example, two cylinder mounting plates 2 and two optical axis mounting plates 1 form a housing. Two through holes are provided on the left and right ends of the lower side of the cylinder mounting plates 2. Each end is fixedly connected to the upper end of an optical axis mounting plate 1 via a hexagon socket screw. The cylinder 3 is arranged between the two cylinder mounting plates 2 and fixed to the cylinder mounting plates 2 via a hexagon socket screw. In this example, the optical axis mounting plate and the cylinder mounting plate are arranged perpendicularly.

[0037] In this example, each optical axis mounting plate 1 is provided with ten countersunk holes, and the ten optical axes 4 are arranged in pairs, for a total of five pairs of optical axes, equidistant and parallel to each other, on the optical axis mounting plate. Each optical axis 4 is mounted horizontally and connected to the countersunk holes on the optical axis mounting plates 1 on both sides. Threaded holes are provided at both ends of the optical axis and are locked to the optical axis mounting plate by hexagon socket screws. In this example, the optical axis can be located at the lower part of the optical axis mounting plate, so that there is sufficient longitudinal space on the optical axis to install the clamping claw.

[0038] Two blocking plates 9 are placed parallel to each other between the two optical axis mounting plates 1. The two telescopic ends of the cylinder 3 are each fixedly connected to a blocking plate 9 via a connector. Each optical axis 4 passes through both blocking plates 9. A spring 5 and a clamping jaw 6 are sleeved on each end of the optical axis 4 (the clamping jaw 6 comprises two clamping jaws, which achieve gripping through their opposing motion). One end of the spring 5 is connected to the optical axis mounting plate 1, and the other end is connected to the clamping jaw. The clamping jaw has a countersunk hole in which a linear bearing 7 is mounted. The linear bearing is mounted on the optical axis 4. A silicone sealing strip 8 is adhered to the lower end of the clamping jaw, providing a certain degree of adaptability when the clamping jaw grasps a bottle. The spring 5 provides clamping force, and the blocking plate 9 prevents the clamping jaw from moving.

[0039] The device of the utility model can be installed at the end of a robotic arm, and the robotic arm controls the lifting and lowering. When the cylinder is closed, the blocking plate contracts and blocks the spring. At this time, the spring compression is minimum and is in a minimum clamping state. When the cylinder is opened, the cylinder drives the blocking plate to push the clamping claw part open. At this time, the cylinder is opened to the maximum, the spring compression is maximum, and the clamping claw is at the maximum stroke. At this time, the device can be controlled to descend and the bottle to be grasped is placed between the clamping claws. The cylinder is closed again and the cylinder drives the blocking plate to contract. At this time, the blocking plate is retracted and the spring elastic force pushes the clamping claw part back. The clamping claw automatically closes until it touches the edge of the bottle and stops. Bottles with different diameters can be adaptively clamped.

[0040] The specific process is as follows Figure 3-5 As shown, specifically: Figure 3 In this example, when the cylinder is closed, the cylinder is closed and the blocking plate blocks the spring. At this time, the spring compression is the smallest and is in the minimum clamping state.

[0041] like Figure 4In this case, when the cylinder is opened, the cylinder drives the blocking plate to push the clamp open. At this time, the cylinder is opened to the maximum, the spring compression is the largest, and the clamp is at the maximum stroke.

[0042] like Figure 5 In this example, the cylinder closes again, and the cylinder drives the blocking plate to retract. At this time, the blocking plate is retracted, and the spring force pushes the clamping jaws back. The clamping jaws automatically close until they touch the edge of the bottle and stop, so that bottles of different diameters can be adaptively clamped.

[0043] In addition, in order to control the clamping jaws in the open state without affecting the bottles already placed in other rows, a limit mechanism 10 is fixed on each of the two optical axis fixing plates 1 to limit the travel of the blocking plate. One end of the limit mechanism is fixed to the optical axis mounting plate, and the other end is close to the blocking plate. Figure 6 In this embodiment, the hexagon socket screw serves as the limiting mechanism. The hexagon socket screw limits the opening stroke of the blocking plate, and the position of the hexagon socket screw can be adjusted to adjust the opening distance of the clamping jaws.

[0044] It should be understood that the embodiments described in this specification are only intended to illustrate the principles of the embodiments of this specification. Other variations may also fall within the scope of this specification. Therefore, as examples and not limitations, the alternative configurations of the embodiments of this specification may be considered consistent with the teachings of this specification. Accordingly, the embodiments of this specification are not limited to the embodiments explicitly introduced and described in this specification. Those skilled in the art should understand that any improvements to the present invention, changes in the number of components, combinations or equivalent replacements, all fall within the scope of protection and disclosure of the present invention.
