Abstract

The utility model discloses a turntable for a braid motor, which is characterized in that a codec is arranged on the turntable for the braid motor through a revolving shaft, and the precision of the codec is 0.1mm. The turntable for the braid motor has the advantages that counting is precise, and problem of inaccurate counting for a product is thoroughly solved.

Description

Braid motor rotating disk

Technical field

The utility model relates to a kind of semiconductor production, particularly relates to the braid motor rotating disk that coder is installed in a kind of semiconductor production.

Background technology

At present, in the production process of semiconductor SMD, qualified product is carried out tape package according to 3K/ dish or 10K/ dish, present equipment permissible error is within positive and negative 5, it is very accurate to be difficult to accomplish, its reason is that the mode of taking is when confirming to have product to come from last station by transducer, the braid motor takes a step forward, produce a counting, equipment is in the process that runs up, the phenomenon that always has jam, when jam took place, motor did not advance according to predetermined mode, caused product to be dropped or damaged, after our these faults of manual process, can not these countings of corresponding change, so can exist counting and actual quantity not to meet problem.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of counting braid motor rotating disk accurately.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of braid motor rotating disk is equipped with a coder through rotating shaft on the rotating disk of braid motor.

The utility model has adopted a coder (precision is 0.1mm) has been installed on the rotating disk of braid motor, software is examined in real time and is surveyed the motor rotating disk status signal that coder is sent, and according to the data that obtain judge the motor rotating disk whether according to the target of being scheduled in operate as normal.

The beneficial effects of the utility model are: counting accurately thoroughly solves the inaccurate problem of product counting.

Fig. 2 is the right view of Fig. 1.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See Fig. 1, shown in Figure 2, a kind of braid motor rotating disk is equipped with a coder 3 through rotating shaft 2 on the rotating disk 1 of braid motor.Described coder precision is 0.1mm.

If can accurately judge the operating state of braid motor rotating disk, go a step further before real promptly whether at every turn, when last station has supplied materials, the motor rotating disk should and also real before go a step further and just count a number, if there is jam to take place, the motor rotating disk does not advance step of standard, in time send warning, and this goes on foot not count number, and after fault was got rid of, preceding physical location can take place to jam by self-return in the motor rotating disk, continue afterwards to carry out, so just can guarantee being absolutely correct of product quantity according to normal step.Realize such function, the utility model has adopted a coder (precision is 0.1mm) has been installed on the rotating disk of braid motor, examine the motor rotating disk status signal that the survey coder is sent in real time with software, and according to the data that obtain judge the motor rotating disk whether according to the target of being scheduled in operate as normal. be exactly with a standard step pitch of braid motor rotating disk 4mm specifically, convert the pulse signal of 40 standards to, the corresponding 0.1mm. of each pulse, under the normal condition, per step all has 40 pulse outputs and is detected, when generation is unusual, motor is obstructed, the umber of pulse of output can be less than 40 (being made as N). after fault is got rid of, send control signal CD-ROM drive motor revert action by software, revert action stops when individual for (40-N) to the reverse impulse number of output. so far, motor has been got back to jam preceding state has been taken place, and corresponding product is also done by software and do not counted processing. and afterwards, whole system will have been recovered again according to normal control mode work.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.

Claims

1. a braid motor rotating disk is characterized in that: through rotating shaft a coder is installed on the rotating disk of braid motor.

2. braid motor rotating disk according to claim 1 is characterized in that: the precision of described coder is 0.1mm.
