Description

Workpiece appearance inspection device

The present invention relates to a device for inspecting the appearance of workpieces, in particular to an arrangement in which the vertical face of the entire row of parts faces the outer periphery of the circular transparent rotary table, so that the metal beads mixed in the process will gradually become transparent as the circular transparent rotary table rotates. The designer of the outer edge of the rotating table is thrown away and will not be stuck in the whole row in reverse.

Press, chip type electronic components generally arrange the visual inspection process after the electroplating process, because a large number of metal beads need to be mixed in order to increase the conductivity during electroplating, and the metal beads must be separated before the visual inspection, but too small, shaped metal beads are inevitably incompletely separated. Mixed into the workpiece.

Second press, TWI480540B (CN103204375B/JP6009167B) discloses a work appearance inspection device, which includes: a linear feeder that transports a hexahedral shape workpiece, a transfer table that transfers and transports the workpiece from the linear feeder, and a linear feeder The workpiece is transferred to the transfer table to arrange the transfer arrangement means, the holding means to hold the workpiece on the transfer table, the photographing means to photograph the six sides of the workpiece, and the gap between the vacuum suction transfer table and the arrangement guide Vacuum suction means; wherein, the transfer arrangement means has a non-vibration portion provided between the linear feeder and the transfer table, and an arrangement guide for arranging the work, the arrangement guide includes a guide that is linear in plan view The surface and the holding means consist of an ion generator ejecting charged ions toward the bottom surface of the transfer table, or a conductor arranged below the transfer table and applying a DC voltage to the conductor to generate an electric field.

Press again, the linear feeder of the previously disclosed patent is a reciprocating vibrating body, and the non-vibrating part is a fixed machine. It must have a gap greater than the amplitude of the linear feeder, which is likely to cause dust to accumulate in the gap and cause jamming or uneven travel of the workpiece; In addition, the conductor that generates an electric field by applying a DC voltage is on the downstream side of the non-vibration section. Before the workpiece enters the transfer table, the linear feeder and the non-vibration section are metal shielding electric fields. After the workpiece is transferred to the transfer table, it suddenly enters the non-vibration section. The electric field is shielded, and the workpiece is polarized by the electric field instantly, causing the workpiece to jump violently, which causes the spread range to become larger, reducing the effect of the entire array; in addition, the spherical metal beads are difficult to be kept on the transfer table, and the guides are arranged on the transfer table disc On the outer side, tin-tip metal beads are easily caught in the gap between the alignment guide and the transfer table due to centrifugal force. The workpiece is blocked by the metal beads caught in the alignment guide and the entire row fails. The entire row of failed workpieces is blocked by the alignment guide and cannot be blocked. Out of the running track, a single failed workpiece will cause multiple workpieces to fail.

In addition, a suction path is provided in the alignment guide to vacuum the gap between the alignment guide and the transfer table. The open end inside the gap attracts the entire row of the workpiece. However, since the alignment guide is a fixed mechanism, the transfer table In order to rotate the glass disc, the machining of the rotating shaft, the accuracy of assembly and the flatness of the glass disc cause the gap between the alignment guide and the transfer table to change continuously, resulting in the continuous change of the suction capacity of the workpiece at the open end and the unstable alignment of the workpiece.

The main purpose of the present invention is to solve the problem that the metal beads mixed in the prior art process are easily stuck in the entire row of parts and cause the failure of the entire row of the workpiece, and have the effect of preventing the metal beads mixed in the process from being stuck in the entire row and causing the failure of the entire row of the workpiece.

Another object of the present invention is to have the work piece progressively polarized, so that the jitter of the work piece is small, so that the spreading range is reduced and the effect of improving the entire row effect is improved.
