A kind of Special manipulator for injection molding machine telescoping mechanism
Technical field
The invention belongs to machining equipment technical field, particularly a kind of Special manipulator for injection molding machine telescoping mechanism.
Background technology
At present, in-mold label is increasingly extensive in the application of household chemicals field and field of seasoning.Because in-mold label has the incomparable advantage of numerous common label, will be the trend of future development.In-mold label relates to material loading, send the multiple working procedures such as mark, feeding and piling.Specifically, manipulator for in-mold label end generally completes following three actions: in limited space, manipulator grasping mechanism first from labeling part storeroom pickup labeling part and move to die sinking complete after the relevant position of injection machine mould die cavity, then by telescoping mechanism after removing electrostatic by laterally inserted for labeling part die cavity; Meanwhile, telescoping mechanism opposite side need take out from punch pasting after die sinking brand-name product; Last action of manipulator grasping mechanism is, by mobile, the product of taking-up is placed into product stacking place.Existing telescoping mechanism mainly has the following disadvantages: one, cost is high: generally adopt servomotor, line rail or two cylinders to realize two-way stretching, which increase production cost, cause the competitiveness of product to reduce; Two, complex structure: the general more complicated of design of current telescoping mechanism, some even needs to utilize the drive mechanism such as tooth bar and line rail; Utilize motor-driven to need to join Timing Belt or other transmission mechanisms, add integrally-built complexity, bring certain requirement to making and installation.
Chinese patent (license notification number: CN202953552U) discloses a kind of telescoping mechanism, and this telescoping mechanism forms primarily of servomotor, Timing Belt, synchronous pulley and line slideway.Flexible grasping mechanism is fixed on Timing Belt by synchronous belt briquetting, finally along with the rotating of servomotor drives flexible grasping mechanism along the direction translation of line rail, thus realizes the function of transversal stretching.But this patent of invention needs servomotor to provide power, also want Timing Belt as transmission system, not only add cost, also requirement is proposed to control aspect, and be unfavorable for regular maintenance.Therefore need modified node method, reduce costs.
