Description

Technical Field

[0001] The utility model relates to the technical field of piece-picking machines, in particular to a piece-picking structure for a coaxial connecting rod piece-picking and spraying integrated machine. Background Art

[0002] The retrieval machine uses a mechanical linkage principle to remove products from the mold and deliver them to a safe area along a pre-planned trajectory. This reduces manual labor, streamlines production processes, and offers safety, stability, and efficiency. For details on the retrieval machine's structure, refer to the Chinese utility model patent application number 202023313802.8 for a retrieval machine with a linkage-type dual-servo mechanism.

[0003] Regarding the existing pickup machine gripper, as shown in the accompanying drawings of the specification Figure 1 As shown, the inventor believes that when the piece-removing machine takes out the workpiece 50, it mainly clamps the protruding parts on the surface of the workpiece 50 through the mechanical gripper 40. In many cases, the protruding parts on the surface of the workpiece 50 are circular tube structures. This makes it easy for the workpiece 50 to fall off due to the rotation of the circular tube structure when it is clamped by the mechanical gripper 40. In particular, when the workpiece 50 is an asymmetric structure, when the mechanical gripper 40 clamps the circular tube structure, the workpiece 50 can easily rotate with the circular tube structure as the center, which can easily cause the workpiece 50 to fall off. If the clamping force of the mechanical gripper 40 is simply increased, it is easier to damage the workpiece 50.

[0004] Therefore, the purpose of this application is to propose a pickup structure for a coaxial connecting rod pickup sprayer to solve the above problems. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a taking structure for a coaxial connecting rod taking sprayer to solve the above problem.

[0006] To achieve the above-mentioned purpose, the utility model provides a picking structure for a coaxial connecting rod picking sprayer, including a picking arm, which is connected to an active arm and a driven arm, and a mechanical gripper for grabbing the workpiece is installed at the head of the picking arm, and is characterized in that the mechanical gripper is provided with an anti-slip mechanism for limiting the workpiece; the anti-slip mechanism includes: a support rod, which is movably connected to the bottom of the mechanical gripper, and the length direction of the support rod is perpendicular to the length direction of the picking arm; a baffle, which is fixed to the head of the support rod, and the mechanical gripper is connected to a rotating drive mechanism for driving the support rod to rotate around its own axis.

[0007] Compared with the prior art, the present invention has the following benefits: The coaxial connecting rod picking sprayer picking structure of the present invention effectively solves the problem that the mechanical gripper is prone to rotation and falling off when clamping the circular tube structure by setting an anti-falling mechanism. The support rod is driven to move to the bottom of the workpiece by the telescopic cylinder, and the support rod is driven to rotate by the motor to realize the limitation of the workpiece between the baffle and the mechanical gripper, ensuring the stability and safety of the workpiece during the picking process and reducing the risk of the workpiece falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0009] Figure 1 It is a schematic diagram of the prior art structure.

[0010] Figure 2 It is a three-dimensional structural schematic diagram of the utility model.

[0011] Figure 3 This is another three-dimensional structural schematic diagram of the present utility model. DETAILED DESCRIPTION

[0012] The following is combined with Figure 1-3 The specific implementation methods of the present utility model are further described in detail.

[0013] Depend on Figure 1-3 The utility model provides a picking structure for a coaxial connecting rod picking sprayer, including a picking arm 30, wherein the picking arm 30 is connected to an active arm 10 and a driven arm 20, and a mechanical gripper 40 for grabbing a workpiece 50 is installed at the head of the picking arm 30. The active arm 10 and the driven arm 20 are parallel connecting rod structures. When in use, under the action of the driving device, the active arm 10 rotates, thereby driving the picking arm 30 together with the driven arm 20 to extend into the work station, and then the workpiece 50 is grabbed by the mechanical gripper 40. The above is the existing technology and will not be repeated here.

[0014] When the structure grasped by the mechanical gripper 40 is a circular tube structure 51, the workpiece 50 is likely to rotate and fall off. To prevent this problem, the mechanical gripper 40 is provided with an anti-falling mechanism 60 for limiting the position of the workpiece 50.

[0015] The anti-slip mechanism 60 includes:

[0016] A support rod 61, the support rod 61 being movably connected to the bottom of the mechanical gripper 40, and the length direction of the support rod 61 being perpendicular to the length direction of the pickup arm 30, and the support rod 61 being used to support the bottom of the workpiece 50, thereby preventing the workpiece 50 from rotating toward one side due to gravity;

[0017] The baffle 62 is fixed on the head of the support rod 61. The mechanical gripper 40 is connected to a rotation drive mechanism 63 that drives the support rod 61 to rotate around its own axis. The rotation drive mechanism 63 can drive the support rod 61 to rotate. When the support rod 61 rotates, it can drive the baffle 62 to rotate. The baffle 62 rotates to block the outside of the workpiece 50, so that the workpiece 50 is limited between the mechanical gripper 40 and the baffle 62, which can prevent the workpiece 50 from moving in the axial direction of the circular tube structure 51, and play a good anti-falling effect.

[0018] In some embodiments, the rotation drive mechanism 63 is a motor.

[0019] In some embodiments, the mechanical gripper 40 is fixed with a vertical slide rail 64, and a telescopic cylinder 65 is slidably provided in the vertical slide rail 64. The head of the telescopic cylinder 65 is fixedly connected to the motor, and the output shaft of the motor is fixedly connected to the rear end of the support rod 61. It can be understood that the vertical distance between the bottom of different workpieces 50 and the mechanical gripper 40 will also be different. Through the setting of the vertical slide rail 64, the telescopic cylinder 65 can be moved in the vertical direction of the mechanical gripper 40, thereby adjusting the position of the support rod 61.

[0020] Specifically, the upper end and the lower end of the vertical slide rail 64 are both threadedly connected with an adjusting bolt 66 , and the head of the adjusting bolt 66 is in close contact with the side surface of the telescopic cylinder 65 .

[0021] The number of the anti-slip mechanism 60 is at least one, and the anti-slip mechanism 60 deviates from the claw of the mechanical gripper 40 in the vertical direction, that is, deviates from the circular tube structure 51 in the vertical direction. It can be understood that the number of the anti-slip mechanism 60 can be one. When the number of the anti-slip mechanism 60 is one, the anti-slip mechanism 60 should be set on the side close to the center of gravity of the workpiece 50. In this way, when the workpiece 50 rotates toward one side of the center of gravity, the support rod 61 can provide support. When the number of the anti-slip mechanism 60 is two, it should be symmetrically set on both sides of the circular tube structure 51.

[0022] The utility model provides a picking structure for a coaxial connecting rod picking sprayer. Through the setting of an anti-falling mechanism 60, when the mechanical gripper 40 is used to pick up the workpiece, the telescopic cylinder 65 is extended to drive the support rod 61 to move to the bottom of the workpiece 50, which can prevent the workpiece 50 from deflecting toward one side. The support rod 61 is driven to rotate by the motor, which can make the blocking piece 62 block the side of the workpiece 50 away from the mechanical gripper 40, so that the workpiece 50 is limited between the blocking piece 62 and the mechanical gripper 40, which plays a good anti-falling effect.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
