Description

A kind of disks grabbing device

Technical field

The invention belongs to dynamo-electric field, be meant a kind of disks grabbing device especially.

Background technology

Since CD came out, extracting from the CD that piles up how can be safe and simple was also put down a CD, is the actual demand of plurality of applications always.For example: the automatic CD up and down of CD writer; The automatic CD up and down of optical media replication equipment; Automatic CD up and down all needs fast and convenient extracting CD on the compact disc production line, under the environment of present office, reduces operating noise as much as possible and becomes important requirement.In plurality of applications, particularly adopted the mode of sucker to grasp CD in some production environments, this mode reliability is high; Speed is fast; Can prevent once to grasp above 1 CD, but because work must be adopted the mode that vacuumizes, vavuum pump is essential equipment; And the operating noise of vavuum pump is not suitable for the application under office environment fully all above 60 decibels.

Develop a kind of each and grasp a CD, low noise and optical disk gripping device simple in structure are the technology that those skilled in the art strive to find, and the inventor is able to propose following application technology through research for a long time.

Novel content

The purpose of the utility model is that exploitation is a kind of simple in structure, easy to use, only grasps the optical disk gripping device of a CD and low noise at every turn.

The utility model is realized through following technical scheme:

A kind of disks grabbing device includes support, Mechatronic Systems and control system; Said Mechatronic Systems is installed on the support, and said control system connects with Mechatronic Systems through lead.

Said Mechatronic Systems includes gripper, alignment pin, back-moving spring, cam, connecting rod and at least one block of electromagnet; Said gripper includes 2-4 strip paw; Said each strip paw is fixed on the support through alignment pin; Said paw is connected by back-moving spring away from the CD end, and a cam is installed in the middle of said 2-4 paw dipped beam dish end, and said cam is connected on the support through axle; The other end of the axle of said cam connects with connecting rod; The connecting rod other end connects with the motion end of electromagnet; Said electromagnet connects with the control system through lead; Said electromagnet is fixed on the support.

The distolateral convex of having looked of said strip paw CD grabbing.

The invention has the beneficial effects as follows:

Technical essential of the present invention is to use conveniently, and only grasps a CD at every turn, and in use noise is low to moderate and can ignores simultaneously.

The specific embodiment

Describe the embodiment of the utility model in detail below in conjunction with accompanying drawing, wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the utility model, and can not be interpreted as restriction the utility model.

With reference to accompanying drawing 1 and Fig. 2, a kind of disks grabbing device includes support, Mechatronic Systems and control system; Said Mechatronic Systems is installed on the support, and said control system connects with Mechatronic Systems through lead.

Said Mechatronic Systems includes gripper, alignment pin 2, back-moving spring 1, cam 3, connecting rod 7 and at least one block of electromagnet 6; Said gripper includes 2-4 the distolateral convex paw of having looked of strip CD pick-and-place; In other embodiment of the utility model, can select the paw of other shape for use, such as semicircular in shape etc.; Said each strip paw is fixed on the support through alignment pin 2; Said paw is connected by back-moving spring away from the CD end, and a cam is installed in the middle of said 2-4 paw dipped beam dish end, and said cam is connected on the support through axle; The other end of the axle of said cam connects with connecting rod; The connecting rod other end connects with the motion end of electromagnet; Said electromagnet connects with the control system through lead; Said electromagnet is fixed on the support.Cam, connecting rod and electromagnet are through changing the position of connecting rod with electromagnet, amplifying moment changes the angle that cam rotates then, promotes the gripper opening and closing, thereby realizes the function of pick-and-place dish.

When this device kept not using, the circumscribed circle diameter of the CD of gripper folding pick-and-place end was less than circular diameter in the CD.

This device is to realize the object of the invention in the following manner:

When electromagnet receives instruction that controller sends when grasping CD, gripper is to be inserted in the endoporus of CD, and the external diameter of gripper is less than the internal diameter of CD.The instruction of input changes the motion end of relay, causes connecting rod to produce change in location.Connecting rod is directly connecting cam, and when connecting rod position changed, cam can produce rotation along with the displacement of connecting rod.Because the Design of length of connecting rod; The moment of the motion end change in location of electromagnet is exaggerated; This moment is converted into the cam rotating moment by connecting rod; Overcome the pressure of gripper back-moving spring, promote the gripper lower end and open up into the maximum position that the CD internal diameter is allowed, gripper makes CD be fixed on the gripper to the tension force that internal diameter produced and the frictional force of CD.

Only grasp a slice CD in order to ensure gripper, the contact-making surface that gripper grasps CD internal diameter position is the thickness of a slice CD at every turn.There is the bossing 4 of particular design the below of gripper contact-making surface, the effect of this part be when cam promotes gripper and opens, separate grasp with the CD of not hoping to grasp.

When electromagnet receives instruction when putting down CD, the instruction of input makes relay under the effect of own back-moving spring, and motion end resets; Under the effect of the back-moving spring of gripper; Cam is resumed original position, the position before gripper is returned to and opens, and at this moment CD is put down.

Can also use two electromagnet at the utility model, to adapt to two shared optical disk gripping devices of controller.

The above only is a preferred implementation of the present invention; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the application's principle; Can also make some improvement and retouching, improve and retouch the protection domain that also should be regarded as the application like this.
