Description

Technical Field

[0001] The invention relates to the technical field of marking in production operations, and in particular to an automatic marking device and a flying probe testing device. Background Art

[0002] With the increasing development of electronic products, the PCB testing industry is moving towards full automation, and the demand is huge. Since the good or bad products after the PCB board inspection need to be marked, the current marking methods include ink marking, laser marking and physical damage marking, but misjudgment may occur in the process before marking, physical damage marking is not easy to change, and laser marking has a high production cost, so ink marking is usually used in the prior art. Due to the fast industrial production speed and the short interval between workpieces, in order to facilitate the rapid drying and forming of the marking, quick-drying ink is required for marking. The problem that follows is that the seal of the marking mechanism is generally exposed to the air when not in use and is easily dried. When it is used again, there will be problems such as failure to mark or unclear marking, and it is necessary to clean or replace the seal, thereby increasing labor costs and reducing production efficiency.

[0039] Among them Figure 1-2 The figure shows an automatic marking device of the present invention, which specifically comprises: a printing device and an isolation device, wherein the printing device comprises a printing unit 8 and a printing cylinder 5, the printing cylinder 5 comprises a cylinder body and a piston rod slidably connected to the cylinder body, wherein the output end of the piston rod of the printing cylinder 5 is connected to the printing unit 8, and the printing unit 8 performs a linear reciprocating motion along its axis under the drive of the printing cylinder 5, as shown in FIG. Figure 1-2 As shown, when the printing cylinder 5 drives the printing unit 8 to move downward, the printing operation is performed, and when the printing unit 8 completes printing, it returns to the starting position as the piston rod of the printing cylinder 5 moves upward. The printing unit 8 in this embodiment preferably adopts an ink printing device.

[0040] The isolation device of this embodiment includes a sealing cover 2, a connecting rod 3 and an isolation cylinder 6, one end of the connecting rod 3 is connected to the isolation cylinder 6, and the other end is connected to the sealing cover 2. The sealing cover 2 is movably connected to the printing unit 8 through the connecting rod 3, so that the sealing cover 2 can seal the printing unit 8 and isolate it from the surrounding air when the printing unit 8 is not performing a printing operation. The isolation cylinder 6 includes a cylinder body and a piston rod movably connected to the cylinder body. The piston rod of the isolation cylinder 6 drives the sealing cover 2 to move between a first position in contact with the printing unit 8 and a second position separated from the printing unit 8 through the connecting rod 3 connected thereto.

The upper end of the connecting rod 3 passes through the through hole on the third mounting plate 12 to connect with the transmission plate 7, and the lower end of the connecting rod 3 passes through the through hole on the second mounting plate 11 to connect with the sealing cover 2, thereby transmitting the power of the isolation cylinder 6 to the sealing cover 2, and the reciprocating motion of the piston rod of the isolation cylinder 6 can realize the flipping of the sealing cover 2 between the first position and the second position.

[0045] In this embodiment, the end portion of the first mounting plate 10 corresponding to the printing unit 8 is also connected to the rotating shaft 9 corresponding to the printing unit 8. Specifically, the lower end portion of the first mounting plate 10 corresponding to the printing unit 8 is provided with a mounting step for mounting the rotating shaft 9 of the sealing cover 2, and the rotating shaft 9 is mounted on the mounting step. The mounting position of the mounting step corresponds to the first position when the printing unit 8 does not perform the printing operation, and the sealing cover 2 contacts and seals the printing unit 8 at this position. In order to ensure the sealing effect, in this embodiment, a groove is provided on the inner side of the sealing cover 2, and a sealing ring 1 for sealing is provided in the groove.
