[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention installs a supporting assembly and a first driving assembly. A transparent tray in the supporting assembly supports the packaging box for movement. During the movement, the first probe, the second probe and the third probe respectively detect the inkjet codes on the top, side and bottom surfaces of the packaging box.

Therefore, the rubber ball will not affect the leftward movement of the mounting frame, and the rotational resistance of the conveyor belt can be effectively reduced. When the mounting frame moves back to the right and resets under the drive of the compression elastic force of the first spring, the rubber ball will directly contact and rub against the tooth plate under the blocking action of the baffle, thereby effectively slowing down the return speed of the mounting frame and preventing the mounting frame from hitting the guide rail and vibrating, causing the electronic components in the second probe and the third probe to loosen.

Example 4: Please refer to Figure 3 , Figure 5 This embodiment further explains the first embodiment, the outer side of the support shaft 10 is movably sleeved with a collar 34, the lower end of the collar 34 is movably abutted with a support ring 35, and the support ring 35 is fixedly sleeved on the outer side of the support shaft 10, the support ring 35 is used to support the collar 34, and the outer side of the collar 34 is fixedly installed with a first clamping seat 36, and the first clamping seat 36 is fixedly connected to the bent support rod 13 through a long connecting rod.

[0027] A first cotton strip 37 is movably embedded in the first holder 36, and the first cotton strip 37 can be movably fitted with the lower end surface of the transparent tray 11 through the first holder 36 and the ring 34. A second holder 38 is fixedly installed on the lower side of the conveyor belt 2 inside the base 1, and the second holder 38 is close to the right end of the base 1. A second cotton strip 39 is movably embedded in the second holder 38. The connection between the first cotton strip 37 and the second cotton strip 39 and the transparent tray 11 is a sliding contact.

The connection between the first cotton strip 37 and the first holder 36, and the connection between the second cotton strip 39 and the second holder 38 is a plug-in connection.

[0028] Working principle: When detecting the inkjet code on the surface of the package box, the robot places the package box on the transparent tray 11, and the conveyor belt 2 transports multiple transparent trays 11. When the package box enters the support cover 3 with the transparent tray 11, the gear 15 will contact the rack 16 during the movement, and the rack 16 will drive the gear 15 and the package box on the transparent tray 11 to rotate. In the process of the package box moving to the left and rotating, the first probe 4 on the support cover 3 detects the inkjet code on the top surface of the package box, the second probe 6 detects the inkjet code on the bottom surface of the package box, and the third probe 7 detects the inkjet code on all sides of the package box, which is conducive to detecting the inkjet code on all surfaces of the package box during the movement of the package box, effectively improving the inkjet code detection efficiency of batch packages. For packages that fail the inspection, the cylinder 41 will push the package box off the transparent tray 11, and the qualified package box will fall at the left end of the machine base 1.

[0029] Before the gear 15 contacts with the rack 16, the roller 21 will enter the interior of the mounting frame 5 through the contact groove 22 and press against the mounting frame 5 through the contact groove 22. When the positioning plate 8 continues to move, the positioning plate 8 will drive the mounting frame 5 to move to the left through the roller 21. That is, when the package box moves to the left and rotates, the second probe 6 and the third probe 7 will move to the left together with the package box, which is beneficial for the second probe 6 and the third probe 7 to fully detect the coding on the side and bottom of the package box. When the push rod 23 moves to the triangular driving block 40 with the positioning plate 8, the triangular driving block 40 will drive the push rod 23 and the roller 21 to move forward through the second ball 26. When the triangular driving block 40 drives the push rod 23 and the roller 21 to move to the front end, the mounting frame 5 will be driven by the compression force of the first spring 19 to separate from the roller 21 through the contact groove 22. After the mounting frame 5 separates from the roller 21, it will be driven by the first spring 19 to move back and reset, so that the second probe 6 and the third probe 7 continue to perform coding detection on the next package box.

[0030] When the mounting frame 5 moves to the left along with the positioning plate 8, the rubber ball 32 in the deceleration assembly is blocked by the tooth plate 33 and rotates to the right, so the rubber ball 32 will not affect the movement of the mounting frame 5 to the left, and can effectively reduce the rotational resistance of the conveyor belt 2. When the mounting frame 5 is separated from the roller 21 and the first spring 19 drives the mounting frame 5 to move back to the right and reset, the connecting rod 28 is blocked by the baffle 31 and cannot rotate to the left, so the rubber ball 32 will directly contact and rub against the tooth plate 33, thereby effectively slowing down the return speed of the mounting frame 5 and preventing the mounting frame 5 from hitting the guide rail 18 and vibrating, causing the electronic components in the second probe 6 and the third probe 7 to loosen.

[0031] During the process of the rack 16 driving the gear 15 and the transparent tray 11 to rotate, the first holder 36 cannot rotate with the transparent tray 11 due to the fixation of the bent support rod 13, so that during the rotation of the transparent tray 11, its lower end surface will slide in contact with the first cotton strip 37, which is beneficial to wiping off the dust attached to the bottom surface of the transparent tray 11; during the process of the transparent tray 11 rotating to the lower side of the conveyor belt 2, the side of the transparent tray 11 away from the first cotton strip 37 will slide in contact with the second cotton strip 39, which is beneficial to wiping off the dust attached to the other side of the transparent tray 11, and can effectively prevent the dust from affecting the detection of the inkjet code on the bottom surface of the packaging box by the second probe 6.
