[0040] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0041] In the description of the present application, it should be noted that unless explicitly defined and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integral connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] In addition, although the terms used in the present application are selected from the commonly known and used terms, some terms mentioned in the specification of the present application may be selected by the applicant according to his or her judgment, and the detailed meanings of which are described in the relevant part of the description.

[0043] In addition, the present application is required to be understood not only by the actual terms used, but also by the meaning implied by each term.

[0044] The technical solutions provided by the embodiments of the present application will be described in detail below in conjunction with the drawings.

[0045] The embodiments of the present application provide a detection device. Referring to Figures 1 to 9 The detection device 1 provided by the embodiments of the present application comprises a base 100, a first camera 210, a second camera 220 and a first transfer device 310. Exemplarily, the first camera 210 and the second camera 220 can be industrial cameras. The first transfer device 310 can be a mechanical hand.

[0046] The detection device 1 is provided with a first shooting station and a second shooting station, and the first camera 210, the second camera 220 and the first transfer device 310 are connected with the base 100 respectively. The first camera 210 is located above the first shooting station, and the second camera 220 is located below the second shooting station. Exemplarily, the lens of the first camera 210 is arranged downward, and then the area below the lens of the first camera 210 is the first shooting station. The lens of the second camera 220 is arranged upward, and then the area above the lens of the second camera 220 is the second shooting station.

[0047] In the embodiment of the present application, the first camera 210 is configured to acquire the image of the top of the to-be-inspected piece 2 located at the first shooting station. For example, when the to-be-inspected piece 2 moves to the first shooting station located below the lens of the first camera 210, the first camera 210 works to acquire the image of the top of the to-be-inspected piece 2.

[0048] Further, the first transfer device 310 is configured to transfer the to-be-inspected piece 2, of which the image of the top is acquired, to the second shooting station. The second camera 220 is configured to acquire the image of the bottom of the to-be-inspected piece 2 located at the second shooting station. For example, when the first transfer device 310 is a mechanical arm, the mechanical arm transfers the to-be-inspected piece 2 to the second shooting station located above the lens of the second camera 220, and then the second camera 220 can acquire the image of the bottom of the to-be-inspected piece 2 located at the second shooting station.

[0049] It should be noted that the first camera 210 and the second camera 220 listed above can be specific examples such as industrial cameras, which are mainly provided to facilitate the understanding of the scheme provided by the embodiment of the present application by those skilled in the art. Those skilled in the art can flexibly select appropriate devices to assemble the detection device 1 according to the needs in the process of implementing the scheme provided by the embodiment of the present application, which will not be described in detail here.

[0050] In this way, in the embodiment of the present application, the first camera 210 and the second camera 220 can be used to acquire the image of the top and the image of the bottom of the to-be-inspected piece 2, respectively. Thus, it is convenient to perform appearance inspection on the to-be-inspected piece 2 based on the image of the top and the image of the bottom.

[0051] It should be noted that since the machine vision technology is quite mature, there are currently commercially available appearance inspection systems based on machine vision. Therefore, the image of the top and the image of the bottom of the to-be-inspected piece 2 acquired by the detection device 1 provided by the embodiment of the present application can be sent to the appearance inspection system based on machine vision, so that the appearance inspection system based on machine vision is used to perform appearance inspection on the to-be-inspected piece 2.

[0052] In addition, if those skilled in the art lack funds to purchase commercially available appearance inspection systems based on machine vision when implementing the scheme provided by the embodiment of the present application, the image of the top and the image of the bottom of the to-be-inspected piece 2 acquired by the detection device 1 can be transmitted to a display device. Thus, the quality inspection personnel can perform appearance inspection on the to-be-inspected piece 2 based on the image of the top and the image of the bottom of the to-be-inspected piece 2 displayed by the display device.

[0053] In this way, the labor intensity of the operator can be reduced by assisting or replacing the quality inspection personnel to perform appearance inspection through the detection device 1.

[0054] refer to Figures 1 to 6 In some embodiments, the testing device 1 further includes a conveying device 400 and a first lifting device 510. The conveying device 400 is used to convey the test piece 2, which is input from a first position of the conveying device 400, to a second position of the conveying device 400. The first lifting device 510 is used to lift the test piece 2 located at the second position, so that the test piece 2 is raised relative to the conveying device 400 to the first imaging station.

[0055] by Figure 2 For example, the first position of the conveying device 400 is located on the right side of the conveying device 400, and the second position of the conveying device 400 is located above the first lifting device 510. The workpiece 2 to be tested can be input into the conveying device 400 via the right side of the conveying device 400. Furthermore, the conveying device 400 can transport the workpiece 2 to be tested from right to left, so that the workpiece 2 to be tested moves to a position above the first lifting device 510.

[0056] Furthermore, after the test piece 2 moves to a position above the first lifting device 510, the first lifting device 510 lifts the test piece 2 at the second position so that the test piece 2 is separated from the conveying device 400.

[0057] Understandably, since the test piece 2 is supported by the first lifting device 510, the imaging of the test piece 2 supported by the first lifting device 510 will not be interfered with when the conveying device 400 transports other test pieces 2. Therefore, when the first lifting device 510 lifts the test piece 2 located in the second position, the first camera device 210 acquires an image of the top of the test piece 2 lifted to the first imaging position. Moreover, during the process of acquiring the image of the top of the test piece 2, the conveying device 400 can simultaneously transport other test pieces 2, thus improving the working efficiency of the inspection equipment 1.

[0058] refer to Figures 1 to 7 In some embodiments, the conveying device 400 is further used to convey the test piece 2 located at the second position to a third position of the conveying device 400. The testing device 1 also includes a second lifting device 520. The second lifting device 520 is used to lift the test piece 2 located at the third position. The first transfer device 310 is used to transfer the test piece 2 lifted by the second lifting device 520 to a second imaging station.

[0059] by Figure 2For example, the third position of the conveying device 400 is located above the second lifting device 520. After the first camera device 210 acquires an image of the workpiece 2 to be inspected, which is lifted by the first lifting device 510, the first lifting device 510 causes the workpiece 2 to be inspected to descend back to the second position of the conveying device 400. The conveying device 400 can transport the workpiece 2 to be inspected from right to left from the second position of the conveying device 400 to the position above the second lifting device 520, thus moving the workpiece 2 to the position above the second lifting device 520.

[0060] Furthermore, the second lifting device 520 can lift the workpiece 2 to be inspected located above it. Then, the first transfer device 310 can transfer the workpiece 2 to be inspected above the second camera device 220 (i.e., the second imaging station). Thus, the second camera device 220 can acquire an image of the bottom of the workpiece 2 to be inspected.

[0061] It should be noted that in some embodiments, when the first shooting station is located in the material handling area of ​​the first transfer device 310, that is, when the first transfer device 310 can obtain the workpiece 2 to be inspected from the first shooting station, the inspection device 1 may not include the conveying device 400, and the first transfer device 310 can directly obtain the workpiece 2 to be inspected from the first shooting station and transfer the workpiece 2 to the second shooting station above the second camera device 220.

[0062] refer to Figure 1 , Figure 2 and Figure 9 In some embodiments, the test piece 2, input from the first position, is carried on the tray 3. The test piece 2 can move with the tray 3 to the second position, the first imaging station, the third position, and the position lifted by the second lifting device 520.

[0063] by Figure 2 For example, the component to be inspected 2 is carried on a tray 3. The tray 3 carrying the component to be inspected 2 is first input into the conveying device 400 from a first position. It should be noted that, exemplary, the component to be inspected 2 can be a circuit board. The conveying device 400 transports the tray 3 carrying the component to be inspected 2 to a second position located above the first lifting device 510. Then, the first lifting device 510 lifts the tray 3 carrying the component to be inspected 2 so that the component to be inspected 2 moves with the tray 3 to the first imaging station. After acquiring an image of the top of the component to be inspected 2, the first lifting device 510 lowers the tray 3 carrying the component to be inspected 2 to the second position of the conveying device 400.

[0064] Further, the conveying device 400 conveys the tray 3 carrying the to-be-inspected piece 2 from the second position of the conveying device 400 to the third position of the conveying device 400. Further, the second lifting device 520 lifts the tray 3 carrying the to-be-inspected piece 2.

[0065] With reference to Figure 3 , Figures 7 to 9 In some embodiments, the first transfer device 310 comprises a driving assembly 311 and an executor 312 connected with each other. For example, the executor 312 is a vacuum chuck. The driving assembly 311 is configured to drive the executor 312 to move, so as to pick up the to-be-inspected piece 2 from the tray 3 lifted by the second lifting device 520 and transfer the to-be-inspected piece 2 to the second shooting station.

[0066] For example, after the second lifting device 520 lifts the tray 3 carrying the to-be-inspected piece 2, the driving assembly 311 drives the executor 312 to move above the to-be-inspected piece 2. Then, the executor 312 picks up the to-be-inspected piece 2. Further, the driving assembly 311 drives the executor 312 to move to the second shooting station above the second camera 220, and then the second camera 220 can obtain the image of the bottom of the to-be-inspected piece 2.

[0067] With reference to Figure 2 and Figure 9 In some embodiments, the tray 3 is provided with a plurality of to-be-inspected piece setting areas 31, and each to-be-inspected piece setting area 31 is configured to carry a to-be-inspected piece 2. In this way, a single tray 3 can carry a plurality of to-be-inspected pieces 2 at the same time, so as to improve the working efficiency of the detection device 1.

[0068] The detection device 1 further comprises a second transfer device 320. For example, the second transfer device 320 is a robot. The second transfer device 320 is connected with the base 100, and the first camera 210 is connected with the second transfer device 320. In other words, the first camera 210 is indirectly connected with the base 100 by being arranged on the second transfer device 320.

[0069] Further, the second transfer device 320 is configured to drive the first camera 210 to move to a position opposite to each to-be-inspected piece 2, respectively. In this way, the first camera 210 can obtain the image of the top of the to-be-inspected piece 2 opposite to the to-be-inspected piece 2 when the first camera 210 is opposite to the to-be-inspected piece 2 by driving the first camera 210 to move to the position opposite to each to-be-inspected piece 2 by the second transfer device 320.

[0070] In other words, the second transfer device 320 can drive the first camera device 210 to move. When the second transfer device 320 drives the first camera device 210 to move above the first object to be inspected 2, the first camera device 210 acquires an image of the top of the first object to be inspected 2. When the second transfer device 320 drives the first camera device 210 to move above the second object to be inspected 2, the first camera device 210 acquires an image of the top of the second object to be inspected 2. In this way, by driving the first camera device 210 to move to a position opposite to each object to be inspected 2 by the second transfer device 320, images of the top of each object to be inspected 2 are acquired respectively.

[0071] refer to Figure 2 , Figure 7 and Figure 9 In some embodiments, the testing device 1 further includes a rotating device 530. The rotating device 530 is used to drive the tray 3, which is lifted by the second lifting device 520, to rotate so that each item to be tested 2 can be located in the picking area of ​​the first transfer device 310.

[0072] by Figure 9 Taking the arrangement of the test pieces 2 on the tray 3 as an example, the first transfer device 310 can first acquire the four test pieces 2 located in the front row on the tray 3, and then move the four test pieces 2 to the second shooting position located above the second camera device 220. Then, the second camera device 220 can acquire images of the bottom of the four test pieces 2. Then, the first transfer device 310 can put the four test pieces 2 back onto the tray 3.

[0073] Furthermore, by driving the tray 3 to rotate 180 degrees using the rotating device 530, the four items to be inspected 2 located in the rear row will rotate to a position equivalent to that in the front row of the tray 3. Then, the bottom images of the remaining four items to be inspected 2 can be obtained in the same way as before.

[0074] In this way, by driving the tray 3 to rotate through the rotating device 530, the material picking area of ​​the first transfer device 310 can be reduced, and the first transfer device 310 can also move each piece to be inspected 2 to the second shooting position located above the second camera device 220.

[0075] refer to Figures 2 to 4 In some embodiments, the conveying device 400 includes a first belt conveyor 410 and a second belt conveyor 420 spaced apart. The opposite sides of the pallet 3 are supported by the first belt conveyor 410 and the second belt conveyor 420, respectively. Thus, the pallet 3 and the item 2 to be tested supported on the pallet 3 can be moved by the synchronously moving first belt conveyor 410 and second belt conveyor 420.

[0076] Referring to Figure 3 In some embodiments, the first jacking device 510 is located between the first belt conveyor 410 and the second belt conveyor 420. The second jacking device 520 is located between the first belt conveyor 410 and the second belt conveyor 420. The second camera 220 is located on a side of the second belt conveyor 420 facing away from the first belt conveyor 410.

[0077] Referring to Figure 1 In some embodiments, the number of the second cameras 220 can be at least two. For example, the number of the second cameras 220 is two. In this way, in the case that the first transfer device 310 moves 4 pieces of the to-be-inspected members 2 to the second shooting station located above the second camera 220 at a time, the images of the bottoms of the 4 pieces of the to-be-inspected members 2 can be acquired simultaneously by using two second cameras 220. Of course, in other embodiments, the number of the second cameras 220 can be flexibly set according to actual needs by those skilled in the art, which will not be listed one by one here.

[0078] Referring to Figure 8 In some embodiments, the first transfer device 310 comprises a driving assembly 311 and an actuator 312 connected with each other. The driving assembly 311 comprises a first linear driver 3111, a second linear driver 3112 and a third linear driver 3113. The three linear drivers are used to drive the actuator 312 to move in the front-rear direction, the left-right direction and the vertical direction, respectively. Exemplarily, the actuator 312 is a vacuum suction cup. The vacuum suction cup can acquire the to-be-inspected member 2 based on the principle of negative pressure adsorption.

[0079] Referring to Figure 5 In some embodiments, the second transfer device 320 comprises a fourth linear driver 321 and a fifth linear driver 322. The fourth linear driver 321 and the fifth linear driver 322 are used to drive the first camera 210 to move in the front-rear direction and the left-right direction, respectively, so that the first camera 210 can be moved to a position opposite to each to-be-inspected member 2, respectively.

[0080] Referring to Figure 6 In some embodiments, the first jacking device 510 comprises a sixth linear driver 511 and a first carrier 512. The sixth linear driver 511 is drivingly connected with the first carrier 512 to drive the first carrier 512 to ascend and descend. The first carrier 512 is used to carry the tray 3. Exemplarily, the first carrier 512 is provided with at least two first positioning members 513. In combination with Figure 9 The tray 3 is provided with at least two first positioning holes 32. In the case that the tray 3 is carried on the first carrier 512, the first positioning members 513 are in one-to-one correspondence with the first positioning holes 32 in positioning cooperation.

[0081] With reference to Figure 7 The detection device 1 comprises a second lifting device 520, a rotating device 530 and a second carrier 540. The second lifting device 520 is a seventh linear driver, and the rotating device 530 is a rotating driver. The second lifting device 520 is drivingly connected with the rotating device 530, and the rotating device 530 is drivingly connected with the second carrier 540. Thus, when the conveying device 400 conveys the tray 3 to above the second carrier 540, the second lifting device 520 can lift the rotating device 530 and the second carrier 540, so that the tray 3 is supported on the second carrier 540, and then the tray 3 is separated from the conveying device 400.

[0082] Exemplarily, the second carrier 540 is provided with at least two second positioning members 541. In combination with Figure 9 The tray 3 is provided with at least two second positioning holes 33. When the tray 3 is supported on the second carrier 540, the second positioning members 541 are in one-to-one correspondence with the second positioning holes 33.

[0083] Exemplarily, each linear driver can be a linear motor, a pneumatic cylinder or a hydraulic cylinder, etc. which can output linear driving force. Exemplarily, each linear driver can also comprise a rotating motor, a pneumatic motor or a hydraulic motor, etc. which can output rotating driving force, and a lead screw threaded transmission mechanism or a gear and rack mechanism, etc. which can convert rotating motion into linear motion. The rotating driver can be a rotating motor, a pneumatic motor or a hydraulic motor, etc. which can output rotating driving force. Exemplarily, the rotating driver can also comprise a linear motor, a pneumatic cylinder or a hydraulic cylinder, etc. which can output linear driving force, and a gear and rack mechanism, etc. which can convert linear motion into rotating motion.

[0084] To make the skilled in the art better understand the scheme provided by the embodiments of the present application, the following will take the tray 3 supporting 8 pieces of to-be-detected members 2 as an example to briefly introduce the working mode of the detection device 1.

[0085] The tray 3 supporting 8 pieces of to-be-detected members 2 is input from the first position on the right side of the conveying device 400. The conveying device 400 conveys the tray 3 supporting the to-be-detected members 2 to the second position above the first lifting device 510. Then, the first lifting device 510 lifts the tray 3 supporting the to-be-detected members 2, so that the to-be-detected members 2 move with the tray 3 to the first shooting station below the first camera 210. Then, the second transfer device 320 drives the first camera 210 to move to the positions opposite to the to-be-detected members 2 respectively, so as to acquire the images of the top of each to-be-detected member 2 respectively.

[0087] Further, the first transfer device 310 can first acquire the four pieces 2 to be detected located in the front row on the tray 3, and then move the four pieces 2 to be detected to the second shooting position above the second camera 220 by the first transfer device 310. Further, the images of the bottom of the four pieces 2 to be detected are acquired by the second camera 220. After the images of the bottom of the four pieces 2 to be detected are acquired, the four pieces 2 to be detected can be placed back on the tray 3 by the first transfer device 310.

[0088] Further, the four pieces 2 to be detected located in the rear row can be rotated to the positions corresponding to the front row of the tray 3 by rotating the tray 3 by 180 degrees by the rotating device 530. Then, the images of the bottom of the remaining four pieces 2 to be detected can be acquired in the original manner. After the images of the bottom of the remaining four pieces 2 to be detected are acquired, the tray 3 can be lowered to the conveying device 400 by the second lifting device 520. Then, the tray 3 carrying the pieces 2 to be detected can be output by the conveying device 400.

[0089] In addition, the images of the top and the bottom of the pieces 2 to be detected acquired by the detection equipment 1 can be sent to the appearance detection system based on machine vision, so that the appearance detection system based on machine vision is used to detect the appearance of the pieces 2 to be detected. Alternatively, the images of the top and the bottom of the pieces 2 to be detected acquired by the detection equipment 1 can be transmitted to a display device. Then, the appearance of the pieces 2 to be detected can be detected by an inspector based on the images of the top and the bottom of the pieces 2 to be detected displayed by the display device.
