Technical Field
[0001] The utility model belongs to the technical field of chip-related equipment, and in particular relates to a multifunctional gripper device capable of taking into account both chip grabbing and paper separation suction. Background Art
[0002] In chip-related equipment, a machine needs multiple types of grippers to grab chip lead frames for different types of products. When grabbing chip lead frames, the chip lead frames are separated by spacers, and a suction nozzle is required to suck the spacers. With the increasing number of product types, using a single style of gripper can no longer meet compatibility requirements. Therefore, in order to save costs, the same machine needs to be compatible with multiple products and also have a suction nozzle to suck the spacers. Summary of the invention
[0003] The utility model aims to provide a multifunctional gripper device which can take into account various types of products and can grasp chip lead frames and absorb separator paper in view of the defects of the prior art.

[0005] The multifunctional gripper device is characterized by comprising a fixed seat, a driving device arranged on one side of the fixed seat, two mobile bases arranged on the fixed seat; the mobile bases are driven to move toward each other by the driving device; and a plurality of clamps and suction nozzles are arranged on the mobile bases. The clamps can match products of different specifications and models through the mobile bases moving toward each other, and the suction nozzles are arranged on the mobile bases, so that the gripper device also has the function of sucking the spacer paper, which reduces the manufacturing cost and saves the installation space of the equipment.
[0006] The invention is further characterized in that the driving device is a stepper motor, the stepper motor drives the synchronous belt to rotate, and the two mobile bases are respectively connected to the two sides of the synchronous belt. The stepper motor can improve the accuracy of adjusting the distance between the clamping jaws to adapt to different products. The two mobile bases respectively connected to the two sides of the synchronous belt can realize a set of driving devices to adjust the distance between the clamping jaws, and also improve the adjustment speed.
[0007] Furthermore: a main synchronous belt pulley and a synchronous belt driven pulley are respectively arranged on both sides of the fixing seat; the synchronous belt is arranged between the main synchronous belt pulley and the synchronous belt driven pulley; the stepping motor directly drives the main synchronous belt pulley to rotate.
[0008] Preferably, the synchronous belt driven wheel is connected to a driven wheel base, and the driven wheel base is fixed to one side of the fixing seat.
[0009] Its further feature is that: the fixed seat is provided with two round shafts, the movable base is provided on the round shafts through linear bearings, and moves toward each other along the round shafts. The movable base provided on the round shafts and linear bearings can move more stably and smoothly, and the accuracy of distance adjustment is improved.
[0010] Preferably, the clamping jaw is a serrated clamping jaw, which is opened and closed by a clamping jaw opening and closing cylinder, so that the product can be clamped stably and reliably.
[0011] Preferably, a position sensor is installed on one side of the fixing seat, and the distance between the clamping jaws is fed back by the sensor, so that the positioning is more accurate.
[0012] The utility model adjusts the distance between the clamping claws through the moving base that moves toward each other to adapt to products of different specifications and models. At the same time, the moving base is also provided with a suction nozzle, so that the gripping device also has the function of sucking the paper separation. The utility model has a compact structure, realizes multiple functions, reduces the manufacturing cost, and also saves the installation space of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG1 is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION
[0014] like Figure 1 As shown, a multifunctional gripper device includes a fixed seat 107, a stepper motor 101 is arranged on one side of the fixed seat 107, and a driven wheel base 108 is arranged on the other side. The main synchronous pulley 102 is connected to the shaft of the stepper motor 101, and a synchronous belt driven wheel 103 is installed below the driven wheel base 108. A synchronous belt is arranged between the main synchronous pulley 102 and the synchronous belt driven wheel 103. A mobile base 104 is connected to both sides of the synchronous belt. Two circular shafts 109 are arranged on the fixed seat 107, and the mobile base 104 is arranged on the circular shaft 109 through a linear bearing 110, and is driven by the synchronous belt to move toward each other along the circular shaft 109. A plurality of serrated jaws 201 and a suction nozzle 202 are respectively arranged on the mobile base 104. The serrated jaws 201 are driven to open and close by a jaw opening and closing cylinder 203 to clamp the product. A position sensor 105 is installed on one side of the fixed seat 107. By feeding back the spacing between the sawtooth clamping jaws 201 through the position sensor 105 , the positioning is more accurate.
[0015] When the utility model is working, according to the specifications of the product, the stepper motor 101 drives the synchronous belt to rotate, and the synchronous belt drives the two moving bases 104 to move toward each other to adjust the spacing. The jaw opening and closing cylinder 203 drives the sawtooth jaw 201 to open and close to clamp the product. When it is necessary to cover the product with a separator paper, the suction nozzle 202 works to suck the separator paper. Thus, two working modes of grabbing the product and sucking the separator paper are realized, which reduces the manufacturing cost and saves the installation space of the equipment.
