Technical Field

[0001] The utility model belongs to the technical field of micro - product arrangement, and more specifically, it relates to a high - speed and high - precision arrangement device. Background Technique

[0002] Micro - parts refer to components with dimensions in the micron level or smaller, which are widely used in various fields such as electronics, machinery, medicine, aerospace, etc. These parts usually have precise dimensions and shapes and are used to form more complex devices or systems.

[0003] In the prior art, when assembling and arranging micro - parts on a tray, the manual arrangement method is usually adopted. This arrangement method not only has low efficiency, but also has a high error rate in the placement direction of products, greatly affecting the assembly efficiency when assembling micro - parts. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a high - speed and high - precision arrangement device, which has the advantages of improving the arrangement efficiency and reducing the error rate of product placement direction.

[0005] To achieve the above - mentioned purpose, the utility model provides the following technical solutions:

[0006] A high - speed and high - precision arrangement device includes a frame. A vision detection component is fixed on the frame. The vision detection component includes a vibrating bowl, a linear vibrating track communicated with the output end of the vibrating bowl, and a front - and - back detection device. An installation frame is installed on the frame beside the vision detection component. An arrangement device is installed on the installation frame. The arrangement device includes: a servo motor, a speed reducer, an arrangement turntable, and a part limiting disk;

[0007] A blanking port is opened on the part limiting disk. A linear driving mechanism I is installed on the installation frame. The output end of the linear driving mechanism I is installed with a chuck. A blanking rod is installed on the chuck. The blanking rod is located directly above the blanking port. A fixture is installed directly below the blanking port. An arrangement plate is placed on the fixture. A linear driving mechanism II for driving the fixture to move is provided below the fixture.

[0008] The advantages of this solution are at least as follows: When arranging parts, the front and back of the parts are distinguished by the front and back detection device and the vibrating bowl, and the properly positioned parts are conveyed into the arranging turntable through the linear vibrating track. At this time, the servo motor and the reducer rotate to drive the arranging turntable to rotate. When the parts move to the blanking port on the arranging turntable, the first linear drive mechanism is started. The first linear drive mechanism drives the chuck at the output end to move up and down with the blanking rod, and the parts are blanked from the arranging turntable onto the arranging plate. At this time, the second linear drive mechanism is started to drive the fixture and the arranging plate to move, and the parts in the arranging turntable are sequentially blanked into the arranging plate. This method not only improves the speed of arranging the parts on the tray, but also avoids the error in the placement direction of the parts under the action of the visual detection component.

[0009] The present utility model is further configured as: A part guiding block is installed on the part limiting disk through a mounting plate. A guiding groove is provided on the part guiding block, and the guiding groove communicates with the output end of the linear vibrating track.

[0010] The advantages of this solution are at least as follows: The guiding block and the guiding groove play a guiding role for the parts to enter the arranging turntable, so that the parts can better enter the arranging turntable from the linear vibrating track.

[0011] The present utility model is further configured as: The first linear drive mechanism is an electromagnet with an output shaft.

[0012] The advantages of this solution are at least as follows: The electromagnet with an output shaft has a faster response speed compared with the cylinder, and can perform continuous actions ten times per second, thus greatly improving the efficiency of arranging the parts on the tray.

[0013] The present utility model is further configured as: An optical fiber assembly is installed on the part limiting disk. The optical fiber assembly includes: a first optical fiber, a second optical fiber, and a third optical fiber. A reset round hole is provided on the arranging turntable.

[0014] The advantages of this solution are at least as follows: The first optical fiber can detect whether there are parts in the arranging turntable during the blanking process to avoid the phenomenon of blanking when there are no parts. The setting of the second optical fiber can detect whether there are parts loaded from the linear vibrating track into the arranging turntable and whether there are parts that have not been blanked. The setting of the third optical fiber and the reset round hole can enable the arranging turntable to return to its original position after rotating one week, so as to reset the arranging turntable.

[0015] The present utility model is further configured as: A stabilizing block is installed on the side wall of the part limiting disk of the second linear drive mechanism. A groove for the blanking rod to extend into is provided on the stabilizing block, and the groove on the stabilizing block is located directly above the blanking port.

[0016] The advantages of this solution are at least as follows: The setting of the stabilizing block can improve the stability of the displacement of the blanking rod, so that the parts can be more stably unloaded from the arranging turntable onto the arranging plate.

[0017] The utility model is further arranged as follows: A proximity switch sensor is installed on the side wall of the second linear drive mechanism. The proximity switch sensor includes a first proximity switch, a second proximity switch, and a third proximity switch. An induction sheet is installed on the side wall of the fixture.

[0018] The advantages of this solution are at least as follows: The setting of the first proximity switch and the second proximity switch facilitates the detection of the extreme positions of the fixture and plays a role in limiting the fixture. The setting of the third proximity switch facilitates the detection of the starting position of the fixture and improves the accuracy of the fixture displacement.

[0019] 1. By setting up the vision detection component and the arranging device, when arranging parts, the front and back of the parts are distinguished by the front and back detection device and the vibrating bowl, and the correctly placed parts are conveyed into the arranging turntable through the linear vibrating track. At this time, the servo motor and the reducer rotate and drive the arranging turntable to rotate. When the parts move to the blanking port on the arranging turntable, the first linear drive mechanism is started. The first linear drive mechanism drives the chuck at the output end to move up and down with the blanking rod, and unloads the parts from the arranging turntable onto the arranging plate. At this time, the second linear drive mechanism is started, driving the fixture and the arranging plate to move, and unloading the parts in the arranging turntable onto the arranging plate in sequence. This method not only improves the speed of arranging the trays, but also avoids the wrong placement direction of the parts under the action of the vision detection component;

[0020] 2. By setting up the part guiding block and the stabilizing block, the guiding block and the guiding groove play a guiding role for the parts to enter the arranging turntable, so that the parts can better enter the arranging turntable from the linear vibrating track. The setting of the stabilizing block can improve the stability of the displacement of the blanking rod, so that the parts can be more stably unloaded from the arranging turntable onto the arranging plate. The first linear drive mechanism is set as an electromagnet with an output shaft. The electromagnet with an output shaft has a faster response speed compared with the air cylinder and can perform 10 continuous actions per second, thus greatly improving the efficiency of arranging the trays;

[0021] 3. By setting up the optical fiber component and the proximity switch sensor, the first optical fiber can detect whether there are parts in the arranging turntable during the blanking process to avoid the phenomenon of blanking without parts. The setting of the second optical fiber can detect whether there are parts loaded from the linear vibrating track into the arranging turntable and whether there are parts not unloaded. The setting of the third optical fiber and the reset round hole can enable the arranging turntable to return to its original position after rotating one week, so as to reset the arranging turntable. The setting of the first proximity switch and the second proximity switch facilitates the detection of the extreme positions of the fixture and plays a role in limiting the fixture. The setting of the third proximity switch facilitates the detection of the starting position of the fixture and improves the accuracy of the fixture displacement. Brief Description of the Drawings
