The RGB color light source 11 faces the area to be detected. In this embodiment, the RGB color light sources 11 are vertically arranged on both sides of the area to be detected, that is, the RGB color light sources 11 are parallel and relatively arranged. The RGB color light sources 11 display ratio and brightness, improve the contrast, so that the two-dimensional code can be focused and recognized more accurately.

[0032] The zoom lens 13 is mounted on the industrial camera 12, and the industrial camera 12 is mounted on the first driving member 14. The first driving member 14 drives the industrial camera 12 to move in the vertical direction, so that the height distance between the zoom lens 13 and the two-dimensional code can be adjusted. The first driving member 14 is mounted on the second driving member 15, and the second driving member 15 drives the first driving member 14 to move horizontally in a direction perpendicular to the transmission direction of the object to be measured, so that the position between the zoom lens 13 and the two-dimensional code can be adjusted in the horizontal direction. The second driving member 15 is mounted on the third driving member 16, and the third driving member 16 drives the second driving member 15 to move in the transmission direction of the object to be measured, so that the position between the zoom lens 13 and the two-dimensional code can be adjusted in the horizontal direction.

[0033] The position and distance between the industrial camera 12 and the QR code are adjusted by the first driving member 14, the second driving member 15 and the third driving member 16, and the QR code is focused and photographed by the zoom lens 13. If the pixels occupied by the photographed QR code are less than the set value or the clarity is not enough, the position of the industrial camera 12 is readjusted by the first driving member 14, the second driving member 15 and the third driving member 16 until the pixels occupied by the photographed QR code or the clarity meets the requirements, and the position of the industrial camera 12 is recorded, that is, the position of the QR code scanning, so that the QR code can be recognized more accurately. After determining the position of the industrial camera 12, the QR code can be transmitted and recognized in batches to improve production efficiency.

[0034] Continue to refer to Figure 1 In some embodiments, the first driving member 14 includes a first mounting seat 141, a first screw rod 142, a first stop seat 143 and a first motor 144.

The first mounting seat 141 is screwed to the first screw rod 142, and the side wall of the first mounting seat 141 abuts and is slidably connected to the first stop seat 143. That is, the abutment between the side wall of the first mounting seat 141 and the first stop seat 143 can limit the first mounting seat 141 from rotating with the first screw rod 142, so that the first mounting seat 141 can move up and down along the first screw rod 142. The first motor 144 drives the first screw rod 142 to rotate, driving the first mounting seat 141 to slide along the first stop seat 143, so that the first mounting seat 141 can change its height conveniently and more accurately.

[0035] In some embodiments, the first driving member 14 further includes a first guide seat 145, the first limiting seat 143 is provided with a first guide groove 146, the first guide groove 146 is adapted to be provided with the first guide seat 145, and the first guide seat 145 is mounted on the first mounting seat 141. In this embodiment, the first guide seat 145 and the first mounting seat 141 are fixed by screw connection, and in other embodiments, they can also be fixed by bonding, integral molding, clamping, etc. The first guide seat 145 is limited to slide with the first limiting seat 143 through the first guide groove 146, so that the sliding direction of the first mounting seat 141 can be better limited, so that the height of the first mounting seat 141 can be changed more stably, thereby changing the height of the industrial camera 12.

[0036] Continue to refer to Figure 1In some embodiments, the second driving member 15 includes a second mounting seat 151, a second screw rod 152, a second stop seat 153 and a second motor 154.

The first driving member 14 is mounted on the second mounting seat 151. In this embodiment, the first motor 144 is screwed to the second mounting seat 151, and the output shaft passes through the second mounting seat 151 to drive the first screw rod 142 to rotate. The second motor 154 drives the second screw rod 152 to rotate and drives the second mounting seat 151 to move. That is, when the second motor 154 drives the second screw rod 152 to drive the second mounting seat 151 to move, it can drive the first driving member 14 to move, thereby realizing the horizontal movement of the industrial camera 12 perpendicular to the transmission direction of the object to be measured.

The third mounting seat 161 is slidably connected to the third guide seat 162, and the third mounting seat 161 moves along the third guide seat 162, that is, the same or opposite direction as the transmission direction of the object to be measured. In this embodiment, the third motor 163 is installed on one side of the third guide seat 162. The third motor 163 drives the conveyor belt to transmit in the third guide seat 162 and drives the third mounting seat 161 to move. In this embodiment, the second limit seat 153 is fixed on the third mounting seat 161, so that it can drive the industrial camera 12 to move along the horizontal direction of the transmission of the object to be measured.
