[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] By providing a plurality of clamping mechanisms, a plurality of FPC circuit boards can be simultaneously coated and subsequently inspected and sorted, and coating efficiency is improved without affecting the overall structure and use of the equipment. The fastening frame 12 can be moved on the base 11 through the electric telescopic rod 13, so as to achieve the clamping and releasing effect of the FPC circuit board. When the clamping mechanism is located at the top of the equipment, that is, below the spray frame 23, coating is carried out. When the clamping mechanism is located directly below the coating position, that is, at the bottom of the equipment, the second motor 10 is operated to drive the transmission shaft 2 9 and the base 11 to tilt slightly to both sides, and the loosened FPC circuit board slides out accordingly according to the tilt direction, so as to achieve the good and inferior sorting function.
[0032] Embodiment 3
[0033] Combined with Figure 1 and attached Figure 3The bracket 1 is located on one side of the cylinder 4 and is rotatably connected to a transmission shaft 3 21. The bracket 1 is externally connected to a side close to the camera 26 with a No. 3 motor 22 that cooperates with the transmission shaft 3 21 to provide power for the rotation of the transmission shaft 3 21. The transmission shaft 3 21 is connected to a photographic frame 20 at one end away from the bracket 1. A transmission shaft 4 24 is rotatably connected to the photographic frame 20.

The shooting angle of the camera 26 can be adjusted through the transmission shaft three 21 and the transmission shaft four 24, so as to facilitate the capture and detection of the coating position on the FPC circuit board.
[0035] Embodiment 4
[0036] Combined with Figure 2 and attached Figure 5 The cylinder 4 is connected with a plurality of collecting grooves 15 matched with the clamping mechanism, the cylinder 4 is connected with a recovery pipe 16 connected with the collecting groove 15, the bracket 1 is connected with a discharge pipe 18 on the side away from the transmission shaft 2, the discharge pipe 18 and one end of the recovery pipe 16 extend to the outside of the cylinder 4 away from the transmission shaft 2 and are rotatably connected, the discharge pipe 18 and the recovery pipe 16 are commonly connected with a sealing sleeve 17 for sealing at the connection between the two to prevent the recovered paint from leaking, the discharge pipe 18 is connected with a pump body 19 for forcefully extracting the paint received in the collecting groove 15 through the recovery pipe 16 and the discharge pipe 18 to prevent the paint residue in the collecting groove 15 from spilling out after the cylinder 4 is rotated to a certain position, causing pollution.

[0038] During the specific implementation of the utility model, when the device is used to perform the coating process on the FPC circuit board, a piece of FPC circuit board is fixed by the clamping mechanism and the electric telescopic rod 13 it carries. As the transmission shaft 2 drives the cylinder 4 to rotate in the bracket 1, the circuit board comes to the top position below the spray rack 23, and is coated according to objective needs through the nozzle installed on the nozzle rack. A small amount of paint scattered by the spraying is caught by the collecting tank 15 on the cylinder 4 below and discharged through the discharge pipe 18. After the coating is completed, the circuit board comes to the side of the camera 26 driven by the rotation of the cylinder 4, and the camera 26 is used to shoot. The coated circuit board is inspected, and its qualification or failure is recorded and communicated through the corresponding control and computing device. When the circuit board is inspected, the remaining clamping mechanisms can also clamp the circuit board for other processes. After the inspection, the circuit board continues to rotate with the cylinder 4 to the position of the sorting place below. The corresponding qualified and unqualified receiving devices can be set below the two ends of the clamping mechanism for easy sorting and receiving. By receiving the results of the detection by the camera 26, after the clamping mechanism releases the circuit board, the transmission shaft 29 drives the base 11 to tilt in a preset direction, so that the qualified circuit board falls to the corresponding receiving place, and the same is true for the unqualified ones.

The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
