Description
Technical Field
The utility model relates to a hole inspection machine technical field especially relates to a positive device is led to belt for hole inspection machine.
Background
In the process of processing the printed circuit board, the punching of the printed circuit board needs to be detected to see whether the hole number and the hole position are correct or not. In the prior art, the hole inspection machine is specially used for the hole drilling quality inspection of the circuit board after hole drilling, after electroplating, after tin spraying and before shipment.
The transmission device of the current hole inspection machine is a traditional belt type conveying device. The belt guide device generally comprises a transmission belt, a driving wheel, a driven wheel, a supporting plate and a motor driving system, wherein the motor drives the driving wheel, the driving wheel drives the transmission belt to rotate through friction force, and the supporting plate supports the transmission belt. But traditional belt conveyor is when being used for examining the quick-witted hole, because the belt conveyor who examines the hole machine is many transmission belt settings at same action wheel and the structure from the driving wheel, transmission belt easily produces little skew during the transportation, influences the precision of examining the hole machine.
SUMMERY OF THE UTILITY MODEL
Therefore, the belt guide device for the hole inspection machine is needed to solve the problem that the transmission belt of the hole inspection machine is easy to generate tiny displacement and affects the precision of the hole inspection machine.
The utility model provides a positive device is led to belt for hole inspection machine, is including leading positive wheel and positioning connection spare, and positioning connection spare includes two connection pieces, the one end of connection piece is provided with opening slant decurrent draw-in groove, the other end of connection piece is provided with the fixed orifices, lead the both ends of positive wheel lock respectively in two the draw-in groove.
In one embodiment, the polarization wheel is made of PM materials.
In one embodiment, the rolling roller is arranged in the middle of the correction wheel, two ends of the correction wheel are respectively provided with a support rod, and the support rods are buckled in the two clamping grooves.
Above-mentioned a belt is led and is just installed for verifying machine, leads the positive wheel and sets up in the below of transmission belt, and connection piece one end is fixed on the verifying machine organism, and other end buckle is leading the both ends of positive wheel, through the fixed position of leading the positive wheel of two connection pieces, makes the transmission belt position through leading the positive wheel can not take place the skew, ensures the hole testing precision of verifying machine.
