Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, and more specifically, to a detection device and automatic assembly equipment. Background Art

[0002] The nail suction device is a component that can automatically suck screws.

[0041] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0042] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0043] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0044] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0045] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0046] like Figures 1 to 6As shown, according to the first aspect of the utility model, a detection device is provided, which is applied to a nail suction device, comprising: at least two light sources, which are respectively located at different sides of a nail suction position of the nail suction device and can emit light beams toward the nail suction position; an optical path component 4, the number of which matches the number of the light sources, and are respectively arranged corresponding to each of the light sources, so that each light beam passing through the nail suction position can be reflected to a set position; an imaging component 3, which is arranged at the set position and can receive each light beam reflected to the set position, so as to simultaneously obtain images of at least two different sides of the screw located at the nail suction position.

[0047] Specifically, the working process of the nail suction device is usually that a large number of screws are manually put into the screw feeder in batches. The feeder arranges the screws in a certain pattern through a vibration plate or a vacuum system, and then transports them to the turntable inside the feeder. The turntable rotates the single screw to the nail suction position in turn, and the manipulator or the picking shaft drives the electric screwdriver and the suction nozzle to the picking position to perform the nail suction action.

[0048] In this embodiment, the detection device is used to judge the state of the screw after the screw is sucked, ensuring that the position state of the screw sucked by it can be in a standard state, which is convenient for the subsequent assembly of the product. Among them, at least two light sources are set, and they are located on different sides of the screw suction position, so as to realize lighting at least two different sides of the screw at the screw suction position, and provide a backlight environment for the screw at the screw suction position to improve the clarity of the image of the screw acquired by the imaging component, and the optical path component 4 located on the opposite side of the light source can reflect the light beam passing through the screw suction position to the set position, and then be received by the imaging component 3 set at the set position, so as to realize imaging of at least two perspectives at the screw suction position.

[0049] The graphical information of the position and state of the screws from at least two viewing angles is analyzed and judged to determine whether the position of the screws is deviated or whether the screws are tilted, thereby ensuring the assembly process of subsequent products. Wherein, each optical path component 4 is located on the opposite side of a light source, which can refer to the opposite side or the oblique side, as long as it is ensured that the light beam emitted by the light source can be transmitted to the optical path component 4 after passing through the nail suction position and reflected by it to the set position.

[0050] In the above-mentioned embodiment, the number of optical path components 4 corresponds to the number of light sources and are located on opposite sides of each light source, so that when the light passes through the nail suction position, part of the light beam in the area where the screw is located will be blocked by the screw, and the remaining part of the light beam continues to be transmitted and reflected through the optical path component 4 to the imaging component 3 to form corresponding image information.

[0051] Among them, the optical path component 4 can be a plane reflector or a prism with a reflective surface. In order to make the light beams of each light source be reflected into the imaging component 3 after passing through the suction pin position, the reflective surface used to reflect the light beam in the optical path component 4 can be matched and designed according to the actual light path propagation requirements. It can be a number equal to the number of light sources or a number greater than the number of light sources. The imaging component 3 can be composed of a device capable of taking pictures and imaging, such as a camera 31, and the utility model does not impose any restrictions on this.

[0052] In the above embodiment, by setting up multiple light sources and a corresponding number of optical path components 4, one imaging component 3 can detect multiple position angles of the screw at the nail suction position. On the one hand, it avoids the problem of incomplete or unrecognizable angles caused by the deviation of the screw along the reflection direction of the light beam when shooting a single angle, thereby improving the accuracy of nail suction state detection; on the other hand, compared with the structure of multiple imaging components 3 required for shooting at multiple angles in the prior art, it simplifies the structure and saves the device cost. In addition, compared with the vacuum recognition detection method, the photographic recognition method provided by the present application is more intuitive and stable.

[0053] Optionally, refer to Figures 4 to 5 There are two light sources, the optical path component 4 includes two prisms, the imaging component 3 includes a camera 31, each of the prisms is respectively arranged corresponding to one of the light sources, and can make the light beams emitted by the light sources be reflected into the range of the lens 311 of the camera 31.

[0054] Specifically, in this embodiment, the two light sources are located on different sides of the nail suction position, providing a backlight environment for the screw at the nail suction position at two viewing angles, thereby improving the clarity of the imaging. Furthermore, corresponding to the two light sources, two prisms are respectively arranged on the opposite sides of the two light sources, so that the light beams emitted by the two light sources are reflected within the range of the lens 311 of the same camera 31, forming two image information. By analyzing the two image information, it can be determined whether the screw at this nail suction position is in a state of deflection, etc., thereby improving the accuracy of detecting the nail suction state of the nail suction device.

[0055] Alternatively, if Figure 1 , Figure 2 and Figure 6 As shown, the nail suction device has multiple nail suction positions, and each of the nail suction positions is provided with at least two light sources and an optical path component 4 matching the number of the light sources; each of the optical path components 4 can make each light beam emitted by each light source passing through the corresponding nail suction position be reflected to the set position, so that the imaging component 3 can receive each light beam reflected to the set position, and simultaneously obtain images of at least two different sides of each screw located at the multiple nail suction positions.

[0056] Specifically, in this embodiment, the nail suction device usually has multiple nail suction positions to improve the assembly efficiency of the product. The present application sets at least two light sources at each nail suction position, and matches and sets multiple optical path components 4, so that the viewing angles of at least two directions of each screw at multiple nail suction positions of the nail suction device can be transmitted to the imaging component 3 at the same time, so that through one imaging component 3, it is possible to simultaneously confirm whether multiple viewing angles of the screws at multiple nail suction positions can be detected for problems such as position deviation or tilt, so that the nail suction device can maintain high-efficiency assembly, and can improve the accuracy of the detection device for detecting the state of its screws, and reduce the equipment cost.

[0057] Optionally, refer to Figure 1 The number of the imaging components 3 is the same as the number of the pin suction positions, and the light beams emitted by at least two light sources at each pin suction position can be reflected to the corresponding imaging components 3 through each of the optical path components 4.

[0058] Specifically, in this embodiment, the number of imaging components 3 can be increased according to actual needs. For example, when the number of nail suction positions is too large, an imaging component 3 can be set at the position corresponding to each nail suction position to simplify the structure of the optical path component 4 and enable multiple cameras 31 to independently detect the nail suction status of the screw at each nail suction position.

[0059] Alternatively, if Figures 3 to 5 As shown, the detection device also includes a supporting component 6, at least two of the light sources are respectively fixed on the supporting component 6, and each of the optical path components 4 and / or the imaging component 3 is respectively movably arranged on the supporting component 6, so that each of the optical path components 4 can reflect each light beam to the set position.

[0060] Specifically, in the present embodiment, each light source and optical path component 4 and imaging component 3 are arranged on a support component 6. On the one hand, the support component 6 can provide support for the above-mentioned components and concentrate them on a unified structure to facilitate their overall assembly with a nail suction device or other equipment, such as a screw feeder. On the other hand, the setting of the support component 6 can adjust the height, inclination and other positional characteristics of the above-mentioned components, so that they can all be located at appropriate positions, and facilitate the corresponding adjustment of the positions of the imaging component 3 and the optical path component 4.

[0061] In the above embodiment, the optical path component 4 is movably mounted on the support component 6, so that it can adjust the distance or angle relative to the position of the light source, so that it can reflect the light beam emitted by the corresponding light source to the set position. The imaging component 3 is also movably arranged on the support component 6, so that when it is difficult to adjust the position of the optical path component 4, the setting position of the imaging component 3 can be adaptively adjusted, so that each light beam can be reflected into the imaging component 3.

[0062] Among them, when each light beam is reflected to the imaging component 3, it can propagate in the same direction or in different directions, as long as it can fall within the imaging range of the imaging component 3. The specific form of the supporting component 6 can be designed according to actual needs, and the utility model does not impose any restrictions on this.

[0063] Alternatively, if Figure 1 to Figure 2 As shown, each optical path component 4 is movably arranged on the supporting component 6, so that the optical path component 4 can move along the first direction and the second direction relative to the light source on the opposite side; wherein the first direction and the second direction are respectively a direction parallel to and a direction perpendicular to the light beam emitted by the light source.

[0064] Specifically, in this embodiment, the optical path component 4 is movably mounted on the supporting component 6, and can move along the first direction and the second direction, so that in actual application, the optical path component 4 can move closer to or farther away from the light source on the opposite side, and move to the left or right relative to the light source, thereby controlling the reflection path of the light beam of the light source, and facilitating the purpose of reflecting each light beam to a set position, that is, reflecting it into the imaging component 3.

[0065] For example, in one embodiment, referring to Figure 6 The optical path component 4 can be realized by an isosceles triangular prism with a reflective surface, and its inclined surface is a reflective surface. Among them, the first light beam 511 emitted by the first light source 51 passes through the first nail suction position 21 along a straight line and propagates to the reflective surface of the first prism 41. At this time, the first prism 41 moves in a direction close to or away from the light source, that is, it can move in the first direction ( Figure 5 The first prism 41 can also move in a direction to the left or right relative to the light source, that is, along the second direction ( Figure 5 The first light beam 511 moves in the Y direction in the imaging component 3.

[0066] As for the second prism 42, when the second light beam 521 emitted by the second light source 52 passes through the first nail suction position 21 along a straight line and propagates to the reflection surface of the second prism 42, the second prism 42 moves toward or away from the light source, that is, it can move along the first direction ( Figure 5The second prism 42 can also move in a direction to the left or right relative to the light source, that is, along the second direction ( Figure 5 Furthermore, after the second light beam 521 is reflected by the reflection surface of the second prism 42, it will still propagate to the first prism 41, and the first prism 41 can also reflect the second light into the imaging component 3 by moving.

[0067] The propagation of the third light beam 531 emitted by the third light source 53 at the second nail suction position 22 set on the right side of the first nail suction position 21 and the fourth light beam 541 emitted by the fourth light source 54 can also refer to the setting method of each component at the first nail suction position 21, so that the third prism 43 and the fourth prism 44 can smoothly reflect the third light beam 531 and the fourth light beam 541 to the imaging component 3, thereby realizing the detection of the nail suction state of the screws at at least two viewing angles at the two nail suction positions, which not only improves the detection accuracy but also reduces the detection cost.

[0068] Alternatively, if Figure 1 Figure 2 , Figure 4 and Figure 5 As shown, the optical path component 4 includes a prism, a prism mounting block 45 and a prism adjustment block 46, and the prism can reflect the light beam; the prism is movably mounted on the prism adjustment block 46 through the prism mounting block 45, so that the prism can move along the first direction, and the prism adjustment block 46 is movably mounted on the supporting component 6, so that the prism can move along the second direction.

[0069] Specifically, in this embodiment, the function of reflecting the light beam of the optical path component 4 can be achieved by an isosceles triangular prism with a reflecting surface. The prism mounting block 45 is used to fix the prism, and the prism adjustment block 46 is used to adjust the movement state of the prism. Figure 4 As shown, a first groove 461 and a second groove 462 can be provided on the prism adjustment block 46, wherein the prism mounting block 45 is assembled in the first groove 461, so that the prism can move along the first direction, that is, move in the direction close to or away from the light source, which can be used to adjust the size of the imaged image, and the prism adjustment block 46 can be assembled on the supporting assembly 6 through the second groove 462, so as to achieve the purpose of driving the prism and the prism mounting block 45 to move together along the second direction.

[0070] In practical applications, the assembly between the prism adjustment block 46 and the prism mounting block 45 and the support assembly 6 may also be achieved in other forms, such as a limiting structure such as a guide rail, and the present invention does not impose any limitation on this.

[0071] Alternatively, if Figures 1 to 4As shown, the support assembly 6 includes a support plate 62 and a mounting plate 63, and at least two light sources and each of the optical path components 4 are movably assembled on the mounting plate 63 or the support plate 62; the mounting plate 63 is arranged on the support plate 62, and the support plate 62 and the mounting plate 63 can make at least two of the light sources be located on different sides of the nail suction position of the nail suction device.

[0072] Specifically, in this embodiment, the size of the support plate 62 can support the mounting plate 63 to the vicinity of the suction pin position according to actual needs, so that after the light source and the optical path component 4 are installed on the mounting plate 63 or the support plate 62, they can be located at a suitable position of the suction pin position to achieve optical path control of the light source beam. The specific forms of the support plate 62 and the mounting plate 63 can be designed according to actual needs.

[0073] In practical applications, the support component may also include a base 61. The nail suction device 2 is usually equipped with a screw feeder 1. The support plate 62 can be fixed on the screw feeder 1. The screw feeder is fixed on the base 61. In this way, by installing the light source and the optical path component 4 on the mounting plate 63 or the support plate 62, the detection device can be stably set at the feed port of the screw feeder, so that each light source and optical path component 4 can be located at a specific position of the screw at the nail suction position to meet the position requirements of each component.

[0074] For example, in one embodiment, a cover plate 64 may be further provided on the upper side of the mounting plate 63, and a through hole 641 may be provided on the cover plate 64, so that the nail-absorbing component (such as an electric screwdriver) of the nail-absorbing device 2 can be located at the position of the through hole 641 to absorb the nail, and after the nail is absorbed, the screw is located at the nail-absorbing position. The provision of the cover plate 64 can prevent external stray light from interfering with the light beam emitted by the light source, improve the clarity of the image information after imaging by the imaging component 3, and further improve the detection accuracy of the detection device.

[0075] Alternatively, if Figure 1 As shown, the imaging component 3 is movably disposed on the supporting component 6, so that the imaging component 3 can receive each light beam reflected to the set position.

[0076] Specifically, in this embodiment, the imaging component 3 is movably arranged on the supporting component 6, so that in the actual assembly process, the specific position of the imaging component 3 can be adjusted so that the light beams reflected by each optical path component 4 can be projected into the appropriate position of the imaging component 3, such as within the range of the lens 311 of the camera 31, so that the image information is more complete and clear.

[0077] Alternatively, if Figure 1As shown, the imaging assembly 3 includes a camera 31, a camera mounting block 32 and a camera adjusting block 33. The camera 31 is movably mounted on the camera adjusting block 33 via the camera mounting block 32, so that the camera 31 can at least move in a direction close to or away from the nail suction position.

[0078] Specifically, in this embodiment, the camera 31 is assembled on the camera adjustment block 33 through the camera mounting block 32, so that when the camera adjustment block 33 moves relative to the support assembly 6, the camera 31 can be adjusted to a suitable position. Among them, the camera mounting block 32 can be movably assembled on the camera adjustment block 33, the camera adjustment block 33 is assembled on the camera mounting seat 34, and the camera mounting seat 34 can be fixed on the base 61 of the support assembly 6, so that the entire detection device is integrated into a whole, which is convenient for the detection device to cooperate with other equipment.

[0079] In one embodiment, a third groove 35 is provided on the camera mounting block 32 , so that the camera 31 can move along the third groove 35 to adjust the position of the camera 31 .

[0080] Alternatively, if Figure 6 As shown, each of the optical path components 4 can reflect each light beam passing through the nail suction position to the set position along the same direction.

[0081] Specifically, in the present embodiment, each optical path component 4 causes each light beam to be reflected in the same direction to a set position, so that the imaging component 3 can receive different light beams emitted by a plurality of light sources, so that the imaging component 3 can fully receive the image information of the light beam emitted by each light source, thereby reducing the difficulty of setting up the imaging component 3 and the functional requirements, and reducing the equipment cost.

[0082] According to the second aspect of the present invention, Figures 1 to 3 As shown, an automatic assembly device is provided, comprising: a nail suction device 2, a screw feeder 1 and the detection device described in the first aspect; the screw feeder 1 is used to feed the nail suction device 2 so that the nail suction device 2 can absorb the screws to the nail suction position.

[0083] Specifically, in the automatic assembly equipment provided in the present application, the nail sucking device 2 is matched with a detection device for detecting the nail sucking state, which can provide at least two view information of the screw at the nail sucking position, so that the determination of the nail sucking state of the screw is more accurate, and when applied to product assembly, it can improve the accuracy of assembly, improve the yield rate and product quality of assembled products. In addition, the nail sucking device 2 is also equipped with a screw feeder 1 for providing screws, so that the nail sucking device 2 can continuously suck screws from the feed port of the screw feeder 1.

[0084] For example, in one embodiment, the first feeder 11 and the second feeder 12 of the screw feeder 1 are used to feed the first electric screwdriver 23 and the second electric screwdriver 24 of the nail suction device 2, so that the screws can be located at the first nail suction position 21 and the second nail suction position 22, respectively, and are respectively adsorbed by the first electric screwdriver 23 and the second electric screwdriver 24. Among them, the first light source 51 and the second light source 52 are set at the first nail suction position 21, and the first light beam 511 and the second light beam 521 are correspondingly emitted. The first prism 41 and the second prism 42 are also set corresponding to the first light source 51, and are used to reflect the first light beam 511 and the second light beam 521 into the lens 311 of the camera 31. The third light source 53 and the fourth light source 54 are set at the second nail suction position 22, and the third light beam 531 and the fourth light beam 541 are correspondingly emitted. The third prism 43 and the fourth prism 44 are also set corresponding to the third light source 53 and the fourth light source 54, and are used to reflect the third light beam 531 and the fourth light beam 541 into the lens 311 of the camera 31.

[0085] Through the above-mentioned structural design, the view information at the two positions of the first nail suction position 21 is transmitted to the camera 31, and the view information at the two positions of the second nail suction position 22 is transmitted to the camera 31. By analyzing and judging each image formed in the camera 31, it is detected whether the nail suction state of the screws at the two nail suction positions is in an offset or tilted state, thereby realizing the further automatic assembly process of the nail suction device.

[0086] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
