Description

Technical Field

[0001] The utility model relates to the technical field of visual detection, in particular to a turntable component used for visual detection. Background Art

[0002] Visual inspection uses image capture to identify surface defects on products. During inspection, the bottom surface of the product, where it contacts the inspection table, is often not captured by the image capture unit. Therefore, in practice, a flipping mechanism is often used to flip the product.

[0003] Most existing flipping mechanisms, such as those described in Chinese Patent Publication No. CN105259182A, titled "An AOI Visual Inspection Device with Automatic Flipping Function," utilize a vacuum suction cup on a gripper to hold the product under inspection, and a flip motor to drive the gripper to flip the product. This type of flipping mechanism involves the execution and coordination of multiple motion processes, including movement of the gripper toward the product, suction and fixation of the gripper to the product, and rotation of the gripper. This requires the coordination of multiple power sources controlled by a controller, resulting in complex structures and high costs, which urgently need to be addressed. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a turntable assembly for visual inspection, which can not only realize the flipping of the product to be inspected, but also has the advantages of simple structure and low cost for performing the product flipping operation.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A turntable assembly for visual inspection includes a turntable that rotates around its own vertical axis on a base, the turntable including an inner circular table and an outer ring table coaxially sleeved on the outer circumference of the inner circular table and rotating synchronously with the turntable, and the table top of the outer ring table constitutes a collection area for placing products for visual inspection, and a flipping area is formed at the joint between the outer ring table and the inner circular table. The table top of the outer ring table can slide downward and be misaligned with the table top of the inner circular table, so that the product located in the flipping area is flipped toward the lowered table top of the outer ring table; the turntable assembly also includes a guide assembly for guiding the product into the flipping area to form a state to be flipped.

[0007] As a further solution of the present invention: the guide assembly includes two positioning baffles distributed at radial intervals along the turntable. When the product rotates with the turntable, a guide channel is formed by the interval between the two positioning baffles to guide the product into the flipping area, and the entrance of the guide channel is an open structure.

[0008] As a further solution of the present invention: an adjustment component is installed on the base, and an adjustment component is installed on the base. The adjustment component is provided with a horizontal adjustment module for adjusting the interval between the two positioning baffles.

[0009] As a further solution of the present invention: the horizontal adjustment modules are divided into two groups distributed in parallel, and the adjustment ends of the two groups of horizontal adjustment modules are respectively fixedly connected to a positioning baffle, and the adjustment component also includes a lifting adjustment module that drives the two groups of horizontal adjustment modules to generate lifting movements.

[0010] As a further solution of the present invention: an inlet baffle is provided on the base and can be swung around a vertical rotating axis. The vertical rotating axis is distributed on the side of the turntable. The plate body of the inlet baffle can be swung to the entrance of the guide channel, and the plate body of the inlet baffle guides the product from the outside to the inside to the entrance of the guide channel.

[0011] As a further solution of the present invention: the inner circular table is rotated around its own vertical axis and fitted on the base, and an axial flat key and an axial keyway that fit each other are provided between the outer wall of the inner circular table and the inner wall of the outer ring table.

[0012] As a further solution of the present invention: a motor is installed on the base, and the output shaft of the motor is coaxially fixedly connected to the bottom of the inner circular table.

[0013] As a further solution of the present invention: a cylinder is fixed on the inner circular table to drive the outer ring table to perform lifting motion.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. After the product is transported to the outer ring table, the outer ring table rotates to rotate the product to the collection area for the first visual collection. After that, as the outer ring table drives the product to continue to rotate, the guide component guides the product on the outer ring table from the outside to the inside to the flipping area, and the table surface of the outer ring table slides downward and is misaligned with the table surface of the inner circular table, causing the product located in the flipping area to flip toward the lower surface of the outer ring table. At this time, the flipped product is located on the outer ring table, and the outer ring table continues to drive the product to rotate, so that the flipped product on the outer ring table moves again to the collection area for the second visual collection. The flipping action of the present application does not require the aid of an external clamping and flipping structure. It only requires a linear power source to drive the axial movement of the outer ring table or the inner circular table on the basis of the original turntable. It has the advantages of simple structure and low cost.

[0016] 2. The diversion channel with an open structure at the entrance is formed by two positioning baffles distributed at intervals. When the position of the product on the turntable deviates from the flipping area, the product can be diverted to the flipping area to ensure stable flipping operation of the product.

[0017] 3. An adjustment component is provided to adjust the spacing and height of the positioning baffles, thereby facilitating the diversion operation for products with different shapes and structures, thereby improving the versatility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0024] The specific structure of the utility model refers to Figure 1-3 As shown, its main structure includes a turntable 20 that rotates around its own vertical axis on the base 10. The turntable 20 includes an inner circular table 21 and an outer ring table 22 that is coaxially sleeved on the outer periphery of the inner circular table 21 and rotates synchronously with the turntable 20. The surface of the outer ring table 22 constitutes a collection area for placing products for visual inspection. The joint between the outer ring table 22 and the inner circular table 21 forms a flipping area. The surface of the outer ring table 22 can slide downward and form an offset with the surface of the inner circular table 21, causing products in the flipping area to flip toward the lower surface of the outer ring table 22. The turntable assembly also includes a guide assembly that guides products into the flipping area to prepare for flipping.

[0025] During actual operation, the product can be transported to the outer ring table 22 by means of a manipulator, a vibrating screen plate or manual placement, and as the outer ring table 22 rotates, the product is rotated to the collection area for the first visual collection. After that, as the outer ring table 22 drives the product to continue to rotate, the guide component guides the product on the outer ring table 22 from the outside to the inside to the flipping area, and the table surface of the outer ring table 22 slides downward and forms an offset with the table surface of the inner circular table 21, and causes the product located in the flipping area to flip toward the lower surface of the outer ring table 22. At this time, the flipped product is located on the outer ring table 22, and the outer ring table 22 continues to drive the product to rotate, so that the flipped product located on the outer ring table 22 moves again to the collection area for the second visual collection. The flipping action of the present application does not require the aid of an external clamping and flipping structure. It only requires a linear power source to drive the axial movement of the outer ring table 22 or the inner circular table 21 on the basis of the original turntable 20.

[0026] Further, such as Figure 1 and Figure 2 As shown, the guide assembly includes two positioning baffles 50 spaced radially along the turntable 20. As the product rotates with the turntable 20, a guide channel is formed between the two positioning baffles 50 to guide the product into the turning area. The entrance of the guide channel is open. The configuration of the guide channel with an open entrance facilitates the product to enter the guide channel more easily.

[0027] On the basis of the above, if Figure 1 As shown, an adjustment assembly 60 is installed on the base 10, and a horizontal adjustment module for adjusting the distance between the two positioning baffles 50 is provided on the adjustment assembly 60 so as to be used for guiding products with different cross-sectional sizes.

[0028] In addition, if Figure 1 As shown, the horizontal adjustment modules are arranged in two parallel groups, and the adjustment ends of the two groups are respectively fixedly connected to a positioning baffle 50. The adjustment assembly 60 also includes a lifting adjustment module that drives the two groups of horizontal adjustment modules to generate lifting movements. The installation of the lifting adjustment module facilitates stable guidance of products of different heights.

[0029] On the basis of the above, in order to further ensure that the product can be stably diverted into the diversion channel, such as Figure 1 and Figure 2 As shown, the base 10 is provided with an inlet baffle 70 that can be swung about a vertical axis 71. Specifically, the vertical axis 71 is located beside the turntable 20. The inlet baffle 70 can swing until it abuts against the end of the outer positioning baffle 50 near the entrance. The plate body of the inlet baffle 70 guides the product from the outside to the inside to the entrance of the diversion channel.

[0030] It is worth mentioning that the introduction baffle 70 can be locked after adjustment by the damping at its vertical shaft 71, or it may be locked by a set screw. In addition, the introduction baffle 70 can also be configured to be able to be raised and lowered.

[0031] In specific implementation, Figure 1 and Figure 3 As shown, the outer ring 22 rotates around its own vertical axis and fits on the base 10. The outer wall of the inner circular table 21 and the inner wall of the outer circular table 22 are provided with a mating axial flat key and axial keyway. Therefore, by simply driving the inner circular table 21 or the outer circular table 22 to rotate, the inner circular table 21 and the outer circular table 22 can simultaneously rotate coaxially and synchronously while also achieving axial relative motion, eliminating the need for two power sources to separately drive the synchronous rotation of the inner circular table 21 and the outer circular table 22. Of course, in implementation, the sliding fit of the slider and the slide groove, as well as the plug-in fit of the shaft and the socket, as in the prior art, can also be adopted to achieve coaxial synchronous rotation and axial relative sliding of the inner circular table 21 and the outer circular table 22.

[0032] In addition, in the specific implementation, the power source for driving the turntable 20 to rotate is preferably installed on the motor 30 on the base 10. Specifically, the output shaft of the motor 30 is coaxially fixedly connected to the bottom of the inner circular table 21, so that the output end of the motor 30 and the inner circular table 21 can remain relatively stationary, thereby improving the service life of the motor 30.

[0033] In addition, since the inner circular table 21 and the outer ring table 22 rotate synchronously, the cylinder 40 that drives the outer ring table 22 to move up and down is preferably fixed on the inner circular table 21, so that the connection between the telescopic end of the cylinder 40 and the outer ring table 22 can remain relatively stationary, thereby improving the service life of the cylinder 40.

[0034] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations that fall within the meaning and range of equivalents of the claims be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0036] The technology, shape and structure that are not described in detail in this utility model are all well-known technologies.
