Description

This invention relates to the technical field of inspection, and in particular to a guide block, a guide assembly, a guide module, and a six-sided visual inspection device.

After the manufacture of electronic components is completed, in order to ensure the quality and performance of the electronic components, it is generally necessary to perform an appearance inspection on the electronic components to obtain information such as the size and shape of the electronic components, and to inspect whether there are defects such as scratches, dents, and oxidation on the surface of the electronic components. In the prior art, the appearance inspection device is generally provided with a feed device, a turntable, a lens inspection device, and a processing system, and the electronic components are moved from the feed device to the turntable, and are sequentially inspected by the lens inspection device as the turntable moves. In the actual inspection process, the electronic components are easily misaligned when they move to the turntable, which adversely affects the subsequent inspection effect. In the prior art, a guide block is provided between the feed device and the turntable to guide the electronic components, but the guiding effect is not good. Therefore, how to improve the position guide effect of the electronic components and evenly arrange the electronic components on the turntable is a problem that needs to be urgently considered and solved.

The present application aims to solve at least one of the technical problems existing in the prior art. Therefore, the present application provides a guide block, a guide assembly, a guide module, and a six-sided visual inspection device to improve the guiding effect of electronic components.

The embodiment of the present application provides a guide module for guiding an electronic component, the guide module including at least a guide rail, a guide assembly, a turntable, and a vacuum device, the guide rail including a guide groove that can accommodate the electronic component, the guide rail being arranged to be capable of transferring the electronic component to the turntable along the guide rail, the turntable being arranged to be capable of moving and driving the electronic component located on the turntable to bring the electronic component into contact with the guide assembly, the guide assembly including a guide block, a partial region of one end of the guide block being provided with an arc surface, the electronic component contacting the guide assembly at the arc surface, the guide block making point contact or line contact with the electronic component via the arc surface to guide the electronic component, and a vacuum groove being provided at an end of the guide block close to the turntable.

The guide module in the embodiment of the present application has at least the following beneficial effects: The guide module includes the guide assembly, the guide assembly includes the guide block, and one end of the guide block is provided with the arc surface. When the electronic component contacts the guide block, it realizes point contact or line contact with the arc surface of the guide block. Compared with the surface contact between the electronic component and the guide module in the prior art, the resistance experienced by the electronic component when it falls from the guide rail to the turntable in the present invention is smaller, the guiding effect of the electronic component is better, the electronic component is more evenly arranged on the turntable, the guiding rate of the guide module is higher, and the structure of the guide module is simpler and the cost is lower.

With the rapid development of electronic technology and its application fields, the requirements for reliability and accuracy in identifying and inspecting electronic components are becoming higher and higher. To inspect electronic components (hereinafter referred to as "components") such as capacitors and resistors, it is usually necessary to receive the components using a supply member, and then transfer the components onto a turntable using a transport member such as a guide rail, and then inspect and classify the components moving together with the turntable.

Figure 1 is a schematic diagram of a guide rail and a turntable in an inspection device. As shown in Figure 1, the guide rail is usually provided above the turntable 12 (Z-axis), has a height difference with the turntable 12, and is inclined with respect to the turntable 12, so that the part 5 placed on the guide rail 11 is transferred along the guide rail 11 under the action of its own gravity. In order to further improve the transfer efficiency, the guide rail 11 is further provided so as to be vibrable, so that the part 5 placed on the guide rail 11 is transferred to the turntable by the synergistic action of gravity and the vibration of the guide rail 11.

With the above method, each part 5 is transferred from the guide rail 11 onto the turntable 12, but it is difficult to arrange each part 5 neatly and evenly. To facilitate subsequent inspection, it is necessary to adjust the position of each part 5 that has fallen onto the turntable 12, i.e., guide each part 5, so that each part 5 to be inspected is arranged on the turntable 12 in a manner that meets the requirements.

In this technical solution, a guide block 3 guides a part 5 that has fallen onto the turntable.

One embodiment of the present application provides a guide assembly 2 including a guide block 3 that not only guides a part 5 on a turntable 12, but also allows the position and angle of the guide block 3 to be adjusted to accurately guide different parts 5 or different scenes.

Another embodiment of the present application further provides a guide module 1 including a guide assembly 2 that guides a part 5 and is not only applicable to various scenes, but can also be combined with other members of the module to improve the operating efficiency of the guide.

The embodiments of the present application are described in detail below with reference to the drawings in the specification.

The embodiment of the present application provides a guide block 3, a guide assembly 2, a guide module 1, and a six-sided visual inspection device 4, and the guide block 3 is provided with an arc surface, thereby improving the guiding effect of the guide block 3 and the guide assembly 2 on the part 5.

The following describes the embodiments of the present application in further detail with reference to the drawings.

The embodiment of the first aspect of the present application provides a guide block 3, and as shown in FIG. 2, a perspective structural schematic diagram of a guide block according to an embodiment of the present application. The guide block 3 includes an upper surface 31, a lower surface 32 and a first end 33 opposite the upper surface 31, and a second end opposite the first end 33, and the second end is provided with a second end surface 34.

In one embodiment, the first end 33 includes a first region 331, a second region 332, a third region 333, and a fourth region 334. The first region 331 is provided between the top surface 31 and the second region 332, i.e., one side of the first region 331 is adjacent to the top surface 31, and the other side is adjacent to the second region 332. The second region 332 is provided between the first region 331 and the third region 333, i.e., one side of the second region 332 is adjacent to the first region 331, and the other side is adjacent to the third region 333. The third region 333 is provided between the second region 332 and the fourth region 334, i.e., one side of the third region 333 is adjacent to the second region 332, and the other side is adjacent to the fourth region 334. The fourth region 334 is provided between the third region 333 and the lower surface 32, i.e., one side of the fourth region 334 is adjacent to the third region 334, and the other side is adjacent to the lower surface 32.

The first region 331, the second region 332, the third region 333, and the fourth region 334 are adjacent to each other in order to form the first end 33 of the guide block 3. The top surface 31, the first region 331, the second region 332, the third region 333, the fourth region 334, the bottom surface 32, and the second end surface 34 of the guide block are connected in order.

The fourth region 334 includes a fourth surface 3341.

In one embodiment, the fourth surface 3341 may be an arc surface. When the part 5 is transferred from the guide rail 11 to the turntable 12, the part 5 rotates with the turntable 12 and contacts the arc surface of the guide block 3, further realizing the guidance of the part 5.

For ease of understanding, the process of guiding the parts 5, i.e., the process of adjusting the position of each part 5 transferred onto the turntable 12 to achieve uniform placement, will be described below.

The part 5 on the guide rail 11 is transferred onto the turntable 12 under the action of the vibration of the guide rail 11 and its own gravity. During operation, the turntable 12 continues to rotate. When the part 5 is transferred onto the turntable 12, the frictional force between the part 5 and the turntable 12 causes the part 5 to move with the rotation of the turntable 12. When the part 5 moves until it comes into contact with the guide block 3, the guide block 3 is fixed and the turntable 12 continues to rotate, so that the part 5 on the turntable 12 is displaced under the reverse thrust of the guide block 3. That is, the part 5 generates a relative displacement with the turntable 12 under the reverse thrust of the guide block 3, which further realizes the guiding of the part 5. After each part 5 transferred onto the turntable 12 is guided by the guide block 3, the orderly arrangement of each part 5 is further realized.

In one embodiment, as the part 5 rotates with the turntable 12, it comes into line contact with the arcuate surface of the guide block 3, further guiding the part 5.

In another embodiment, the part 5 comes into point contact with the arcuate surface of the guide block 3 as it rotates with the turntable 12, further guiding the part 5.

Figure 3 is a schematic diagram of a part rotating with the turntable contacting the guide block. As shown in Figure 3, the part 5 makes line or point contact with the fourth surface 3341 of the guide block 3. At this time, the part 5 receives a thrust F at the position of the contact line/point. Under the action of the thrust F, the position of the part 5 changes, realizing further guidance. Compared to the prior art where the part 5 and the guide block 3 are in surface contact, by guiding the part 5 in the above manner, the part 5 in this embodiment receives a smaller force from the guide block 3 when moving on the turntable 12, resulting in a more accurate guiding effect.

As shown in FIG. 4, which is a front view of a guide block according to one embodiment of the present application, in some embodiments, the first region 331 includes a first surface 3311, the second region 332 includes a second surface 3321, and the third region 333 includes a third surface 3331.

In some embodiments, the angle between the first surface 3311 and the top surface 31 is greater than or equal to 180° and less than or equal to 270°.

In some embodiments, the angle between the second surface 3321 and the first surface 3311 is greater than or equal to 180° and less than or equal to 270°.

In some embodiments, the angle between the third surface 3331 and the second surface 3321 is greater than or equal to 180° and less than or equal to 270°.

An included angle α is formed between the first surface 3311 and the top surface 31, and the included angle α is 180° or more and 270° or less; an included angle β is formed between the second surface 3321 and the first surface 3311, and the included angle β is 180° or more and 270° or less; and an included angle γ is formed between the third surface 3331 and the second surface 3321, and the included angle γ is 180° or more and 270° or less. Included angles are formed between the top surface 31 and the first surface 3311, between the first surface 3311 and the second surface 3321, and between the second surface 3321 and the third surface 3331, respectively. Various angles may be formed between the regions of the first end 33 of the guide block 3 to accommodate contact between the guide block 3 and components 5 of various sizes.

Furthermore, the extensions of the third surface 3331 and the lower surface 32 form an included angle θ, which is 60° or more and 75° or less. Figure 5 is a partial enlarged schematic diagram of part B of the guide block in Figure 4. As shown in Figure 5, a fourth surface 3341 is provided between the third surface 3331 and the lower surface 32. The extensions of the third surface 3331 and the lower surface 32 form an included angle θ. With the above configuration, the third region 333 of the guide block 3 is inclined to one side of the second end surface 34, forming an escape space in the Z-axis direction of the lower surface 32, and preventing the third region 333 from contacting the component 5 and impairing the guide effect.

In one embodiment, the included angle α between the first surface 3311 and the upper surface 31 is 210°, the included angle β between the second surface 3321 and the first surface 3311 is 240°, the included angle γ between the third surface 3331 and the second surface 3321 is 210°, and the included angle θ between the third surface 3331 and the lower surface 32 is 60°. Angles are formed between the upper surface 31 and the first surface 3311, between the first surface 3311 and the second surface 3321, between the second surface 3321 and the third surface 3331, and between the third surface 3331 and the lower surface 32. The second region 332 and the third region 333 of the guide block 3 are recessed on one side of the second end face 34, forming an escape space in the Z-axis direction of the lower surface 32, and preventing the first region 331, the second region 332, and the third region 333 from contacting the part 5 and impairing the guide effect.

As shown in FIG. 5, the fourth region 334 of the guide block 3 includes a fourth surface 3341, which is an arcuate surface.

In one embodiment, the arcuate surface includes a part 5 contact line, which is made up of a set of points on the arcuate surface that are furthest from the second end surface 34 and extends from a first side 35 of the guide block 3 to a second side 36 opposite the first side 35. More specifically, the part 5 contact line extends from a fifth region 335 of the guide block 3 to a second side 36 opposite the fifth region 335.

In some application scenarios, the contact point between the part 5 and the guide block 3 is on the part 5 contact line. The part 5 and the guide block 3 are in line contact or point contact. Because the size and weight of the part 5 to be inspected are small, if the external force received is too large, it is likely to cause a large displacement, and even cause the part 5 to deviate from the desired position. With the above method, the friction force (reverse thrust) received by the part 5 from the guide block 3 is smaller than in surface contact, making the position adjustment more accurate and the guiding effect better.

In some embodiments, the radius of the arc surface may be between 0.01 and 1 mm.

In a preferred embodiment, the radius of the arc surface is 0.05 mm. Setting the radius of the arc surface to 0.05 mm not only ensures arc surface contact between the part 5 and the fourth region 3341 of the guide block 3, but also realizes line or point contact between the part 5 and the arc surface, ensures that the part 5 receives a constant reverse thrust from the guide block 3, and further allows the position of the part 5 to be accurately adjusted.

As shown in FIG. 6, this is a bottom view of a guide block according to one embodiment of the present application. In some embodiments, the bottom surface 32 of the guide block 3 is provided with a vacuum groove 321 and a vacuum passage 322, and the vacuum groove 321 is connected to the vacuum passage 322.

In some embodiments, the vacuum passage 322 is connected to the vacuum device 13, which achieves a vacuum effect in combination with the vacuum passage 322 and the vacuum groove 321. When the vacuum device 13 is turned on, the vacuum groove 321 communicates with the vacuum passage 322, creating a vacuum environment near the vacuum groove 321 on the lower surface 32 of the guide block 3, reducing the flow of gas near the lower surface 32 of the guide block 3, and further reducing the impact on the positional movement of the component 5.

7 is a top view of a guide block according to an embodiment of the present application. As shown in FIG. 7, in some embodiments, the first end 33 of the guide block 3 further includes a fifth region 335, which is connected to the first side 35, the first region 331, the second region 332, the third region 333, and the fourth region 334, respectively. The fifth region 335 includes a fifth surface 3351, which is an arc-shaped surface. The arc-shaped surface is connected to the upper surface 31, the first surface 3311, the second surface 3321, the third surface 3331, the fourth surface 3341, and the first side 35, respectively. The fifth surface 3351 is an arc-shaped surface, and after the part 5 moves from the second side 36 of the guide block 3 to the first side 35 of the guide block 3 along the Y axis, it gradually decelerates and gradually leaves the guide block 3, is evenly positioned on the turntable 12, and moves with the turntable 12. By providing an arc-shaped surface in the fifth region 335, the force that the part 5 receives from the guide block when it moves to the fifth region 335 is reduced, the speed of the part 5 relative to the turntable 12 gradually approaches zero, and the part 5 falls smoothly onto the turntable 12 and rotates together with the turntable 12.

Figure 8 is a schematic perspective view of a guide assembly according to an embodiment of the present application. As shown in Figure 8, the guide assembly 2 is an embodiment of the second aspect of the present application, and the guide assembly 2 includes a guide block 3, a base 21 for fixing the guide block 3, and a position adjustment device 22 for mounting the base 21 and capable of adjusting the position of the guide block 3. The base 21 includes a first end 211 of the base and a second end 212 of the base that is disposed opposite the first end 211 of the base. The first end 211 of the base includes a first surface 2111 of the base, a second surface 2112 of the base, and a third surface 2113 of the base. The second surface 2112 of the base is located between the first surface 2111 of the base and the third surface 2113 of the base, i.e., one side of the second surface 2112 of the base is adjacent to the first surface 2111 of the base, and the other side of the second surface 2112 of the base is adjacent to the third surface 2113 of the base. The second surface 2112 of the base and the third surface 2113 of the base form a base 2114, and the guide block 3 may be disposed in the base 2114, i.e., the second end surface 34 of the guide block 3 contacts the second surface 2112 of the base, and the lower surface 32 of the guide block 3 contacts the third surface 2113 of the base. The second end 212 of the base includes a second end surface 2122 of the base, and the second end surface 2122 of the base is connected to the position adjustment device 22. The guide block 3 is connected to a position adjustment device 22 via a base 21, which controls the positional relationship of the guide block 3 with respect to the turntable 12 and ensures the stability of the position of the guide block 3 during operation.

The vertical distance between the first surface 2111 of the base and the second end surface 2122 of the base is greater than the vertical distance between the third surface 2113 of the base and the second end surface 2122 of the base. The first surface 2111 of the base and the third surface 2113 of the base form a height difference in the vertical direction, which height difference forms a concave step portion at the first end 211 of the base, and the second surface 2112 of the base connects the first surface 2111 of the base and the third surface 2113 of the base. The second surface 2112 of the base and the third surface 2113 of the base form a base 2114 for accommodating the guide block 3, and the second end surface 34 of the guide block 3 contacts the second surface 2112 of the base, and the lower surface 32 contacts the third surface 2113 of the base and is provided within the base 2114.

In some embodiments, a fourth surface 2115 of the base is further provided between the first surface 2111 of the base and the second surface 2112 of the base, i.e., one side of the fourth surface 2115 of the base is adjacent to the first surface 2111 of the base and the other side is adjacent to the second surface 2112 of the base. The end of the fourth surface 2115 of the base adjacent to the first surface 2111 of the base is away from the base 2114, and the end of the fourth surface 2115 of the base adjacent to the second surface 2112 of the base is close to the base 2114, so that the fourth surface 2115 of the base is inclined. The fourth surface 2115 of the base provides a clearance space when assembling the guide block 3 to the base 2114, and facilitates the installation and fixing of the guide block 3.

The guide block 3 is mounted on the base 2114 and is in contact with the second surface 2112 and the third surface 2113 of the base. The guide block 3 is in close contact with the second surface 2112 and the third surface 2113 of the base, i.e., a vacuum is formed between the second end surface 34 of the guide block 3 and the second surface 2112 of the base, and between the lower surface 32 of the guide block 3 and the third surface 2113 of the base, which causes the guide block 3 to shake during operation, causing the magnitude and direction of the force of the guide block 3 acting on the component 5 to be non-uniform, and further preventing the guide effect of the component 5 from being impaired.

The end of the guide block 3 away from the second surface 2112 of the base includes the first end 33 of the guide block 3, and the first end 33 includes the fourth region 334. The fourth region 334 includes a fourth surface 3341, and the fourth surface 3341 is an arcuate surface. The arcuate surface includes a part 5 contact line, which is made up of a set of points on the arcuate surface that are farthest from the second end surface 34, and which extends from the first side 35 of the guide block 3 to the second side 36 opposite the first side 35. More specifically, the part 5 contact line extends from the fifth region 335 of the guide block 3 to the second side 36 opposite the fifth region 335.

In some application scenarios, the contact point between the part 5 and the guide block 3 is on the part 5 contact line. The part 5 and the guide block 3 are in line contact or point contact. Because the size and weight of the part 5 to be inspected are small, if the external force received is too large, it is likely to cause a large displacement, and even cause the part 5 to deviate from the desired position. With the above method, the friction force (reverse thrust) received by the part 5 from the guide block 3 is smaller than in surface contact, making the position adjustment more accurate and the guiding effect better.

The position adjustment device 22 is provided near the second end surface 2122 of the base, and is capable of adjusting the base 21 connected thereto and the guide block 3 connected to the base 21. It also adjusts the position of the contact line of the component 5 relative to the guide rail 11 and the turntable 12. The component 5 that has fallen from the guide rail 11 onto the turntable 12 is brought into contact with the guide block 3 at the contact line of the component 5, and the magnitude and direction of the force that the component 5 receives from the guide block 3 are also adjusted.

In some embodiments, the position adjustment device 22 includes a first parallel plate 2211, a first parallel axis 2212, a second parallel plate 2213, a second parallel axis 2214, and a bottom plate 2215. The first parallel axis 2212 is located between the first parallel plate 2211 and the second parallel plate 2213, and the second parallel axis 2214 is located between the second parallel plate 2213 and the bottom plate 2215. A certain distance is provided between the first parallel plate 2211 and the second parallel plate 2213, and the first parallel plate 2211 and the second parallel plate 2213 can rotate around the first parallel axis 2212. A certain distance is provided between the second parallel plate 2213 and the bottom plate 2215, and the second parallel plate 2213 and the bottom plate 2215 can rotate around the first parallel axis 2212. The first parallel plate 2211, the second parallel plate 2213, and the bottom plate 2215 are stacked, and the first parallel axis 2212 and the second parallel axis 2214 are arranged to intersect, thereby realizing multi-angle position adjustment of the position adjustment device 22 and further realizing multi-angle adjustment of the position of the guide block 3.

In some embodiments, the first parallel axis 2212 and the second parallel axis 2214 are arranged perpendicular to each other, and the first parallel axis 2212 and the second parallel axis 2214 limit the adjustment direction of the position adjustment device 22 and are adjustable within a 360° range.

In some embodiments, the first parallel axis 2212 is arranged parallel to the Y axis, and the second parallel axis 2214 is arranged parallel to the X axis. The first parallel plate 2211 is rotatable around the first parallel axis 2212, i.e., the first parallel plate 2211 is rotatable around the Y axis. The second parallel plate 2213 is rotatable around the second parallel axis 2214, i.e., the second parallel plate 2213 is rotatable around the X axis. Furthermore, the guide block 3 is rotatable around the Y axis or the X axis, respectively, to adjust the gap between the guide block 3 and the turntable 12 and make the lower surface 32 of the guide block 3 parallel to the plane of the turntable 12. Since the size of the parts 5 is small and any slight position or size deviation during operation will affect the guiding effect of the guide block 3, a position adjustment device 22 is provided to adjust the position of the guide block 3 to meet the operating requirements.

9 is a top view of a guide assembly according to an embodiment of the present application. As shown in FIG. 9, in some embodiments, the guide block 3 is fixed in the base 2114 of the base 21, and the base 21 is fixed to one side of the position adjustment device 22. The position adjustment device 22 further includes a first adjustment screw 2221, a second adjustment screw 2223, a first positioning screw 2231, and a second positioning screw 2232, and the first adjustment screw 2221, the second adjustment screw 2223, the first positioning screw 2231, and the second positioning screw 2232 are provided through the first parallel plate 2211. By adjusting the positional relationship between the first parallel plate 2211, the second parallel plate 2213, and the bottom plate 2215, the position adjustment of the guide block 3 can be realized, and the optimal guiding effect can be achieved by adjusting it to the appropriate position.

10 is a cross-sectional view of the guide assembly shown in FIG. 9 taken along the line A-A. As shown in FIG. 10, in some embodiments, the position adjustment device 22 includes a first adjustment screw 2221 and a first compression spring 2222. A first groove 2225 is provided on the surface of the first parallel plate 2211 close to the second parallel plate 2213, and a second groove 2226 is provided on the surface of the second parallel plate 2213 close to the first parallel plate 2211, and the second groove 2226 is provided corresponding to the first groove 2225. The first groove 2225 forms a storage space in the first parallel plate 2211, and the second groove 2226 forms a storage space in the second parallel plate 2213, and the two storage spaces are provided opposite each other to form a space for storing the first compression spring 2222. The first compression spring 2222 is disposed in the space formed by the first groove 2225 and the second groove 2226. The first adjustment screw 2221 is provided in the first compression spring 2222, penetrating the first parallel plate 2211 and the second parallel plate 2213. By turning the first adjustment screw 2221, the first compression spring 2222 is compressed or released to adjust the distance between the first groove 2225 and the second groove 2226, thereby adjusting the included angle between the first parallel plate 2211 and the second parallel plate 2213, and rotating the first parallel plate 2211 around the first parallel axis 2212, i.e., rotating the first parallel plate 2211 around the Y axis, and further adjusting the position of the guide block 3.

In some embodiments, the position adjustment device 22 further includes a second adjustment screw 2223 and a second compression spring 2224. A third groove 2227 is provided on the surface of the second parallel plate 2213 close to the bottom plate 2215, and a fourth groove 2228 is provided on the surface of the bottom plate 2215 close to the second parallel plate 2213, and the fourth groove 2228 is provided corresponding to the third groove 2227. The third groove 2227 forms a storage space in the second parallel plate 2213, and the fourth groove 2228 forms a storage space in the bottom plate 2215, and the two storage spaces are provided opposite each other to form a space for storing the second compression spring 2224. The second compression spring 2224 is disposed in the space formed by the third groove 2227 and the fourth groove 2228, and the second adjustment screw 2223 is provided in the second compression spring 2224 through the second parallel plate 2213 and the bottom plate 2215. By turning the second adjustment screw 2223, the second compression spring 2224 is compressed or released to adjust the distance between the third groove 2227 and the fourth groove 2228, thereby adjusting the included angle between the second parallel plate 2213 and the bottom plate 2215, and rotating the second parallel plate 2213 around the second parallel axis 2214, i.e., rotating the second parallel plate 2213 around the X-axis, and further adjusting the position of the guide block 3.

In some embodiments, the position adjustment device 22 includes a first positioning screw 2231 and a second positioning screw 2232, and the first positioning screw 2231 passes through the first parallel plate 2211 and abuts against the second parallel plate 2213. The first positioning screw 2231 fixes the first parallel plate 2211 and the second parallel plate 2213, thereby preventing large relative displacement between the first parallel plate 2211 and the second parallel plate 2213. The second positioning screw 2232 passes through the second parallel plate 2213 and abuts against the bottom plate 2215. The second positioning screw 2232 fixes the second parallel plate 2213 and the bottom plate 2215, thereby preventing large relative displacement between the second parallel plate 2213 and the bottom plate 2215.

The size of the component 5 to be inspected is small, and any slight position or deviation during operation of the guide block 3 will affect its guiding effect, so it is necessary to be able to adjust the position of the guide block 3 within a small range. The first adjustment screw 2221, the first compression spring 2222, the second adjustment screw 2223, the second compression spring 2224, the first positioning screw 2231, and the second positioning screw 2232 are provided to realize fine adjustment of the positions of the first parallel plate 2211, the second parallel plate 2113, and the bottom plate 2215, and further to realize fine adjustment of the position of the guide block 3.

After the adjustment is complete, check whether the airflow in the vacuum gap 14 is uniform to determine whether the position adjustment device 22 has adjusted the position appropriately.

11 is a perspective structural schematic diagram of a guide assembly 2 according to yet another embodiment of the present application. As shown in FIG. 11, in some embodiments, the guide assembly 2 further includes a vacuum device 13, which communicates with a vacuum passage 322, and which includes a filter 15, a negative pressure display device 16, and a negative pressure regulator 17. The filter 15 filters foreign matter in the air to prevent foreign matter in the air from impairing the vacuuming effect. The negative pressure regulator 17 adjusts the negative pressure value. The negative pressure display device 16 displays the negative pressure value adjusted by the negative pressure regulator 17, so that the operator can set an appropriate vacuum negative pressure. The vacuum device 13 communicates with a vacuum passage 322, which communicates with a vacuum groove 321 provided on the lower surface 32 of the guide block 3. When the vacuum device 13 is turned on, a vacuum is created around the vacuum groove 321 on the lower surface 32 of the guide block 3, applying a suction force to the part 5 toward the guide block 3, accelerating the movement of the part 5 toward the guide block 3. Furthermore, the guide block 3 comes into contact with the part 5 and guides it.

Figure 12 is a structural schematic diagram of a guide module according to an embodiment of the present application. As shown in Figure 12, the guide module 1 according to the embodiment of the third aspect of the present application guides the part 5 and includes a guide rail 11, a guide assembly 2, a turntable 12, and a vacuum device 13. The guide rail 11 includes a guide groove 111, in which the part 5 is placed, that is, the guide groove 111 can accommodate the part 5. The guide rail 11 is provided so that the part 5 can be moved along the guide rail 11 to the turntable 12. The part 5 continues to move to the turntable 12 within the guide groove 111 due to the vibration of the guide rail 11 and its own gravity, and finally falls onto the turntable 12. The turntable 12 is provided so that the part 5 located on the turntable 12 can be rotated, and the part 5 rotates together with the turntable 12 until it contacts the guide assembly 2. The guide assembly 2 includes a guide block 3, which has a second end surface 34 and a first end 33 opposite the second end surface 34, the first end 33 including a fourth region 334, and the fourth region 334 has an arcuate surface. The arcuate surface includes a part 5 contact line, which is made up of a set of points on the arcuate surface that are farthest from the second end surface 34, and which extends from a first side 35 of the guide block 3 to a second side 36 opposite the first side 35. More specifically, the part 5 contact line extends from a fifth region 335 of the guide block 3 to a second side 36 opposite the fifth region 335.

In some application scenarios, the contact point between the part 5 and the guide block 3 is on the part 5 contact line. The part 5 and the guide block 3 are in line contact or point contact. Because the size and weight of the part 5 to be inspected are small, if the external force received is too large, it is likely to cause a large displacement, and even cause the part 5 to deviate from the desired position. With the above method, the friction force (reverse thrust) received by the part 5 from the guide block 3 is smaller than in surface contact, making the position adjustment more accurate and the guiding effect better.

When using the guide module 1 in one embodiment of the present application, the turntable 12 rotates at a constant speed from the guide rail 11 in the direction of the guide block 3, and the parts 5 fall from the guide groove 111 of the guide rail 11 onto the turntable 12, move toward the guide block 3, and are arranged on the turntable 12 in order. A vacuum groove 321 is provided on the lower surface 32 of the guide block 3, and the vacuum groove 321 is connected to the vacuum device 13, which applies a suction force to the guide block 3 to the parts 5, accelerating the movement of the parts 5 toward the guide block, and making the parts 5 adhere to the guide block 3, and further performing position guidance. The guide block 3 is provided with an arc surface, and the parts 5 make point contact or line contact with the arc surface of the guide block 3. The parts 5 fall onto the turntable 12 under the thrust from the guide rail 11, rotate together with the turntable 12, and are arranged on the turntable 12 in an orderly and equal interval under the synergistic effect of the drop frequency of the guide block 3 and the rotation frequency of the turntable 12. The guide module 1 has a higher guide rate, a simpler structure, and lower costs.

As shown in FIG. 6, the guide block 3 is provided with a vacuum passage 322, and a vacuum groove 321 is provided at the end of the lower surface 32 of the guide block 3 close to the turntable 12. The vacuum device 13 communicates with the vacuum passage 322, which in turn communicates with the vacuum groove 321 provided in the lower surface 32 of the guide block 3. When the vacuum device 13 is turned on, a vacuum is created around the vacuum groove 321 on the lower surface 32 of the guide block 3, applying a suction force to the part 5 toward the guide block 3 and accelerating the movement of the part 5 toward the guide block 3. Furthermore, the guide block 3 comes into contact with the part 5 and guides it.

FIG. 13 is a schematic diagram of a partial structure of a guide module according to an embodiment of the present application. As shown in FIG. 13, in some embodiments, a gap 14 is provided between the end of the guide block 3 close to the turntable 12 and the turntable 12, and a vacuum groove 321 is provided on the lower surface 32 of the guide block 3, one end of the vacuum groove 321 communicates with the gap 14, and the other end of the vacuum groove 321 communicates with a vacuum passage 322 provided in the guide block 3. The vacuum device 13 connects to the vacuum groove 321 through the vacuum passage 322 to put the gap 14 between the turntable 12 and the guide block 3 into a vacuum state, thereby preventing gas from flowing through the gap 14 and applying a force in an uncertain direction to the component 5, which causes an unpredictable positional deviation of the component 5 and impairs the positional guide effect of the component 5. In addition, the vacuum device 13 applies a suction force to the component 5 toward the guide block 3, accelerating the movement of the component 5 toward the guide block 3. In addition, the guide block 3 contacts the component 5 and guides the component 5.

12, in the guide block according to one embodiment of the present application, the radius of the turntable 12 that passes through the center of the turntable 12 and is perpendicular to the length direction of the guide block 3 intersects the guide block 3 at point P, or a straight line that is perpendicular to one end face of the guide block and passes through the center of the turntable intersects one end face of the guide block at point P. The distance along the Y axis between the second side 36 of the guide block 3, which is the distance between the side of the guide block 3 closer to the guide rail 11 and point P, and point P is less than the distance along the Y axis between the first side 35 of the guide block 3, which is the distance between the side of the guide block 3 away from the guide rail 11 and point P. Due to the difference in the front-rear distance between the guide block 3 and point P in the Y axis direction, the magnitude of the reaction force that the part 5 receives at different parts of the guide block 3 differs, which contributes to the uniform arrangement of the guide block 3 on the turntable 12. The part 5 is guided to a position on the turntable 12 by the action of the guide block 3 in the process of moving to point P on the front side of the guide block 3. After passing point P, the part 5 moves to the rear side of the guide block 3, the force acting on the part 5 from the guide block 3 becomes smaller, and the part 5 falls smoothly onto the turntable 12 and is evenly arranged on the turntable 12.

In some embodiments, the distance along the Y axis between the second side 36 of the guide block 3, which is the distance between the end of the guide block 3 close to the guide rail 11 and point P, is greater than the distance along the Y axis between the first side 35 of the guide block 3, which is the distance between the end of the guide block 3 away from the guide rail 11 and point P. Due to the difference in the front-rear distance between the guide block 3 and point P in the Y axis direction, the magnitude of the reaction force that the part 5 receives at different parts of the guide block 3 differs, which contributes to the uniform arrangement of the guide block 3 on the turntable 12. The part 5 is guided to a position on the turntable 12 by the action of the guide block 3 during the process of moving to point P at the front end of the guide block 3. After passing point P, the part 5 moves to the rear end of the guide block 3, and the action that the part 5 receives from the guide block 3 becomes smaller, so that the part 5 falls smoothly onto the turntable 12 and is evenly arranged on the turntable 12.

In some embodiments, an electrostatic device is provided at the bottom end of the turntable 12, the electrostatic device is disposed opposite the guide block 3, and the turntable 12 is disposed between the guide block 3 and the electrostatic device. The electrostatic device provides an electrostatic attraction force, and by applying a downward electrostatic attraction force to the component 5, the possibility of misalignment of the component 5 as it rotates on the turntable 12 is reduced.

The six-sided appearance inspection device 4 further includes a frame 41, a storage and supply system 42, a control system, an appearance inspection module, a discharge module, and a computer system. The storage and supply system 42 supplies parts 5, and the parts 5 are transferred onto the turntable 12 by the guide rail 11 of the guide module 1, and are guided to a position by the force of the guide block 3 of the guide assembly 2, and are evenly arranged on the turntable 12. The evenly arranged parts 5 rotate with the turntable 12 and move to the appearance inspection module to perform six-sided appearance inspection. The control system controls the inspection process in combination with the computer system, and processes and stores the inspection data. The discharge module collects and classifies the inspected parts 5.
