Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0038] For the convenience of subsequent description, before describing the specific structure of the detection device, the present application first combines Figure 1 to define a first direction (X) and a second direction (Z). Among them, the first direction is the length direction of the detection device when it is normally placed, for example, the X direction; the second direction is the height direction of the detection device when it is normally placed, for example, the Z direction; the third direction is the width direction of the detection device when it is normally placed, for example, the Y direction. In the present application, the first direction (X) and the second direction (Z) are perpendicular to each other.
[0039] See Figures 1 to 2 as shown in Figure 1 FIG. shows a side view of an embodiment of a detection device provided by the present application, Figure 2 and FIG. shows a structural schematic diagram of an embodiment of a detection device provided by the present application.
[0040] In some embodiments, the detection device includes: a first transmission unit 10, a second transmission unit 20, a first photographing unit 30, and a second photographing unit 40.
[0041] The first transmission unit 10 is used to contact the bottom surface or the top surface of the target product and transmit the target product along the first direction; the second transmission unit 20 is sequentially arranged with the first transmission unit 10 along the first direction, and is used to contact the top surface or the bottom surface of the target product and transmit the target product along the first direction.
[0042] The first photographing unit 30 is located above the first transmission unit 10 along the second direction, and is used to photograph the top surface or the bottom surface of the target product located on the first transmission unit 10; the second photographing unit 40 is located below the second transmission unit 20 along the second direction, and is used to photograph the bottom surface or the top surface of the target product located on the second transmission unit 20.
[0043] In the embodiment of the present application, the first transmission unit 10 and the second transmission unit 20 are arranged to sequentially transmit the target product. Among them, the first transmission unit 10 contacts the bottom surface or the top surface of the target product, and when the first shooting unit 30 is located above the first transmission unit 10, it can shoot the front or the back of the target product; the second transmission unit 20 contacts and transmits the target product on the front or the back of the target product, and the second shooting unit 40 is arranged directly opposite to the second transmission unit 20 below the second transmission unit 20 to shoot the bottom surface or the top surface of the target product, so as to realize the all-round shooting of the target product and effectively eliminate the shooting blind area of the target product.
[0044] Among them, the first transmission unit 10 and the second transmission unit 20 adopt a method of contacting and transmitting the target product on different surfaces, which can effectively avoid blocking the first shooting unit 30 and the second shooting unit 40.
[0045] In some embodiments, as shown in Figures 3 to 4 the detection device further includes a blowing mechanism 60. The blowing mechanism 60 includes a first blowing mechanism and a second blowing mechanism arranged at intervals in the first direction. The first blowing mechanism is located between the first shooting unit 30 and the second shooting unit 40 in the first direction; the second blowing mechanism is located on the side of the second shooting unit 40 away from the first shooting unit 30 in the first direction.
[0046] In the embodiment of the present application, the first blowing mechanism and the second blowing mechanism are respectively arranged behind the first shooting unit 30 and the second shooting unit 40, so that it can combine the current computer vision detection technology. When there are unqualified phenomena such as dirt and defects on the target product, the target product can be directly blown out by the first blowing mechanism or the second blowing mechanism. Exemplarily, the first blowing mechanism is communicatively connected to the first shooting unit 30, and the second blowing mechanism is communicatively connected to the second shooting unit 40.
[0047] In some embodiments, the end of the first transmission unit 10 in the first direction and the head of the second transmission unit 20 are arranged opposite to each other in the second direction.
[0048] In the embodiment of the present application, the end of the first transmission unit 10 and the head are arranged opposite to each other to ensure that the target product can change the contact surface, that is, be transmitted from the first transmission unit 10 to the second transmission unit 20. Exemplarily, when the target product is transmitted to the second transmission unit 20 along the first transmission unit 10, the first transmission unit 10 does not stop transmitting, and the target product is adsorbed by the second transmission unit 20 at the relative part of the first transmission unit 10 and the second transmission unit 20.
[0049] In some embodiments, the detection device further includes a third transfer unit 50, which is spaced from the first transfer unit 10 along the first direction and is used to contact and transfer the target product with the bottom or top surface of the target product. The head end of the third transfer unit 50 is disposed opposite to the tail end of the second transfer unit 20 along the second direction.
[0050] In the embodiments of the present application, the third transfer unit 50 is provided to smoothly transfer the target product transferred by the second transfer unit 20 and facilitate the transfer of the target product to the discharge port 90. Exemplarily, the second blowing mechanism is located on one side of the third transfer unit 50 close to the second photographing unit 40 along the first direction.
[0051] Since the second transfer unit 20 uses an adsorption transfer method, the blowing mechanism cannot smoothly blow the target product off the transfer track. Therefore, the second blowing mechanism is disposed on the third transfer unit 50 to facilitate blowing off the unqualified target products located on the third transfer unit 50.
[0052] In some embodiments, the second transfer unit 20 is provided with a negative pressure assembly 21, and the negative pressure assembly 21 can make the inside of the second transfer unit 20 in a negative pressure state and adsorb the top or bottom surface of the target product.
[0053] In the embodiments of the present application, the second transfer unit 20 transfers the target product by a negative pressure adsorption transfer method, thereby effectively achieving contact with the top or bottom surface of the target product. Among them, negative pressure adsorption is not easy to damage the target product.
[0054] Exemplarily, the negative pressure assembly 21 includes an adsorption table and a negative pressure pump. The adsorption table is provided with a negative pressure chamber, and the negative pressure chamber is communicated with the negative pressure pump through an air pipe, so that the negative pressure pump can make the negative pressure chamber in a negative pressure state. In addition, a transmission belt (such as a transmission belt) is provided to cover the negative pressure chamber and is communicated with the negative pressure chamber through air holes, thereby forming a suction cup type point. And since generally the target product is completed by a punching process, the negative pressure adsorption method can firmly adsorb the target product when contacting the target product. For example, the target product forms a negative pressure cavity with the transmission belt under the action of negative pressure.
[0055] That is, the target product can be adsorbed to the transmission belt by the air holes, and then the top of the target product contacts the adsorption belt.
[0056] In some embodiments, a photoelectric induction device 70 is further provided at one end of the first transfer unit 10 and / or the second transfer unit 20 along the first direction, and the photoelectric induction device 70 is electrically connected to the first photographing unit 30 and / or the second photographing unit 40.
[0057] In the embodiments of the present application, an optoelectronic induction device 70 is added so that when the target product is transported to the first shooting unit 30 along the first transport unit 10, the first shooting unit 30 can perform a shooting action, or when the target product is transported to the second shooting unit 40 along the second transport unit 20, the second shooting unit 40 can perform a shooting action. The first transport unit 10 and the second transport unit 20 can both be provided or both not be provided.
[0058] Combined Figure 5 as shown Figure 5 shows a schematic three-dimensional structure diagram of an embodiment of the first shooting unit 30 of a detection device provided by the present application.
[0059] In some embodiments, the first shooting unit 30 and / or the second shooting unit 40 includes a plurality of lateral cameras 32 and a front camera 31, and the plurality of lateral cameras 32 are circumferentially arranged around the front camera 31.

When both the first shooting unit 30 and the second shooting unit 40 are provided with a plurality of lateral cameras 32 and a front camera 31, the captured images can also be superimposed on each other.
[0061] In some embodiments, the first shooting unit 30 and / or the second shooting unit 40 further includes a camera adjustment device 33, and the camera adjustment device 33 is used to adjust the shooting angles of the lateral cameras 32 or the front camera 31.
[0062] In the embodiments of the present application, the camera adjustment device 33 is provided to adjust the shooting angles of the front camera 31 and the lateral cameras 32, so that it can adapt to different types of target products, that is, it can focus on target products of different specifications.
[0063] In some embodiments, the transport unit further includes a feed inlet 80 and a discharge outlet 90, and the feed inlet 80 and the discharge outlet 90 are arranged at intervals along the first direction.
