With the rapid development of electronic technology and application fields thereof, the requirements on the reliability and accuracy of element identification and detection are higher and higher. Counter element

Such as capacitance, resistance, etc., it is often necessary to receive the component through a feed member, transfer the component to a turntable through a transfer member such as a rail, and then the component is moved with the turntable and inspected and sorted, etc.

FIG. 1 is a schematic view of a guide rail and a turntable in a detection device. Referring to fig. 1, the guide rail is generally disposed above the turntable 12 (Z-axis) with a height difference from the turntable 12 and is inclined with respect to the turntable 12 so that the component 5 placed on the guide rail 11 is transferred along the guide rail 11 by its own weight. In order to further increase the transfer efficiency, the guide rail 11 is also arranged to be able to vibrate, so that the element 5 placed on the guide rail 11 is transferred to the turntable by means of gravity while being vibrated by the guide rail 11.

In this way, the components 5 are transferred from the guide rail 11 to the turntable 12, and it is difficult to make the components 5 placed neatly and uniformly. For facilitating the subsequent detection, the position of each component 5 falling onto the turntable 12 needs to be adjusted, i.e. each component 5 is guided, so that each component 5 to be detected is placed on the turntable 12 in a satisfactory manner.

In the technical scheme, the guide block 3 guides the element 5 falling onto the turntable.

An embodiment of the present application provides a guide assembly 2 including a guide block 3, not only can guide an element 5 on a turntable 12, but also can adjust the position and angle of the guide block 3 to guide an element 5 or different scenes accurately.

The utility model also provides a guide module 1 including guide subassembly 2, not only can lead and be suitable for the scene of not using to component 5, can also cooperate other parts of module, improves the operating efficiency who leads.

Embodiments of the present application will be described in detail below with reference to the drawings attached to the specification.

The embodiment of the application provides a guide block 3, guide subassembly 2, guide module 1 and six visual detection equipment 4, through set up the cambered surface on guide block 3, improves guide block 3, guide subassembly 2 to the guide effect of element 5.

Embodiments of the present application are further described below with reference to the accompanying drawings.

An embodiment of the first aspect of the present application provides a guide block 3, and referring to fig. 2, a schematic perspective view of a guide block provided in an embodiment of the present application is provided. The guide block 3 comprises: an upper surface 31, a lower surface 32 opposite the upper surface 31, a first end 33, and a second end opposite the first end 33, the second end having a second end surface 34 disposed thereon.

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 disposed between the upper surface 31 and the second region 332, i.e., one side of the first region 331 is adjacent to the upper surface 31 and the other side is adjacent to the second region 332. The second region 332 is disposed between the first region 331 and the third region 333, that is, 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 disposed 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 disposed 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.

It will be appreciated that the first region 331, the second region 332, the third region 333, and the fourth region 334 are contiguous in sequence, forming the first end 33 of the guide block 3. The upper surface 31, first region 331, second region 332, third region 333, fourth region 334, lower surface 32, and second end surface 34 of the guide block are connected in sequence.

Fourth region 334 includes fourth surface 3341.

In one embodiment, the fourth surface 3341 may be curved. When the element 5 is transferred from the guide rail 11 to the turntable 12, the element 5 rotates along with the turntable 12 and contacts with the cambered surface of the guide block 3, so that the element 5 is guided.

For easy understanding, the following describes the alignment process of the components 5, that is, the process of adjusting the positions of the components 5 transferred to the turntable 12 to achieve uniform alignment.

The element 5 on the rail 11 is transferred to the turntable 12 under the effect of the vibration of the rail 11 and its own weight. In operation, the turntable 12 remains rotated. When the element 5 is transferred to the turntable 12, the element 5 is moved with the rotation of the turntable 12 by means of friction between the element 5 and the turntable 12. When the element 5 is moved into contact with the block 3, the element 5 on the turntable 12 is displaced by the reaction of the block 3, since the block 3 is fixedly arranged and the turntable 12 is continuously rotated. I.e. the element 5 is pushed back against the guide block 3, and is positioned opposite the turntable 12, thereby achieving the guiding of the element 5. The elements 5 transferred onto the turntable 12 are guided by the guide blocks 3, so that the ordered arrangement of the elements 5 is realized.

In one embodiment, the element 5 is in line contact with the arcuate surface of the guide block 3 during rotation with the turntable 12, thereby effecting alignment of the element 5.

In another embodiment, the element 5 is in point contact with the cambered surface of the guide block 3 during rotation along with the turntable 12, so that the element 5 is guided.

FIG. 3 is a schematic illustration of the contacting of an element rotating with a rotating disk with a guide block. Referring to fig. 3, the element 5 is in line or point contact with the fourth surface 3341 of the guide block 3. At this point, the element 5 is subjected to a thrust force F at the contact line/point. The element 5 is subjected to a thrust force F to change its position, thereby achieving alignment. By means of the above-mentioned mode, the element 5 is guided, the element 5 is intersected with the guide block 3 in the prior art to form surface contact, in the embodiment, the acting force of the guide block 3 when the element 5 moves on the turntable 12 is smaller, and the guiding effect is more accurate.

Referring to fig. 4, a front view of a guide block is provided in accordance with an 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 first surface 3311 makes an angle with the upper surface 31 of 180 ° or more and 270 ° or less.

In some embodiments, the second surface 3321 includes an angle of 180 ° or more and 270 ° or less with the first surface 3311.

In some embodiments, the third surface 3331 forms an angle with the second surface 3311 of 180 ° or more and 270 ° or less.

It will be appreciated that the first surface 3311 forms an angle α with the upper surface 31 of 180 ° or more and 270 ° or less; an included angle β is formed between the second surface 3321 and the first surface 3311, 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 3311, the included angle γ is 180 ° or more and 270 ° or less. The upper surface 31 forms an included angle with the first surface 3311, the second surface 3321, and the third surface 3331, respectively. The various regions of the first end 33 of the guide block 3 may be angled differently to accommodate the contact of the differently sized elements 5 with the guide block 3.

The extension lines of the third surface 3331 and the lower surface 32 form an included angle θ, and the included angle θ is 60 ° or more and 75 ° or less. Fig. 5 is an enlarged partial schematic view of the portion B of the guide block of fig. 4. Referring to fig. 5, a fourth surface 3341 is disposed between the third surface 3331 and the lower surface 32. An extension of the third surface 3331 forms an angle θ with an extension of the lower surface 32. By the above arrangement, the third region 333 of the guide block 3 is inclined toward the second end face 34 side, and a space is formed in the Z-axis direction of the lower surface 32, so that the third region 333 is prevented from contacting the element 5, and the guiding effect is prevented from being affected.

In one embodiment, the angle α between the first surface 3311 and the upper surface 31 is 210 °; the angle β between the second surface 3321 and the first surface 3311 is 240 °; the angle γ between the third surface 3331 and the second surface 3311 is 210 °; the angle θ between the third surface 3331 and the lower surface 32 is 60 °. The upper surface 31 and the first surface 3311, the first surface 3311 and the second surface 3321, the second surface 3321 and the third surface 3331, and the third surface 3331 and the lower surface 32 form an included angle therebetween. The second area 332 and the third area 333 of the guide block 3 are concave towards the second end face 34, a avoidance space is formed in the Z-axis direction of the lower surface 32, the first area 331 and the second area 332 are prevented from being contacted with the element 5, and the guiding effect is prevented from being influenced.

Referring to fig. 5, fourth region 334 of guide block 3 includes a fourth surface 3341, fourth surface 3341 being arcuate.

In one embodiment, the arcuate surface comprises a line of contact of the element 5, the line of contact of the element 5 consisting of a collection of points on the arcuate surface furthest from the second end surface 34 and extending from a first side 35 of the guide block 3 to a second side 36 opposite the first side 35. More specifically, the element 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 of element 5 with guide block 3 is located on the element 5 contact line. The element 5 is in line or point contact with the guide block 3. Because the size and weight of the element 5 to be measured are small, the element 5 is easily displaced greatly due to the action of external force, and the element 5 is deviated from the expected position. By the mode, the friction force (reverse thrust) from the guide block 3 received by the element 5 is smaller than the surface contact, the position of the element is adjusted more accurately, and the guide effect is better.

In some embodiments, the radius of the arc may be selected to be 0.01-1mm.

In a preferred embodiment, the radius of the arc is 0.05mm. When the radius of the cambered surface is set to be 0.05mm, the contact between the element 5 and the cambered surface of the fourth area 3341 of the guide block 3 can be ensured, the line contact or the point contact between the element 5 and the cambered surface can be realized, the element 5 is ensured to receive the reverse thrust of a certain size of the guide block 3, and the accurate adjustment of the position of the element 5 is further realized.
