As shown in fig. 1 to 3, the utility model provides a die pad frock at bottom of electricity core, including platform 100 and the movably setting that is used for fixing a position die pad 300 the operation portion 200 of platform 100 top, be equipped with on the platform 100 and be used for making die pad 300 is in spacing post 110 on the platform 100, be equipped with on the operation portion 200 and be used for the glued adhesive deposite device of die pad 300 with be used for with die pad 300 is placed the platform 100 is followed the device of getting taken away on the platform 100 is put. According to the above, the utility model provides an electricity core base plate frock can effectively fix a position the base plate, gets fast to put and combines the point to glue the operation, effectively reduces production time, raises the efficiency, increases the productivity.

As shown in fig. 1, in order to effectively limit the position of the bottom bracket piece 300 when the bottom bracket piece 300 is just placed on the platform 100, a deep groove 120 for initially positioning the bottom bracket piece 300 is formed on the upper surface of the platform 100, the shape of the deep groove 120 corresponds to the outline of the bottom bracket piece 300, and the limit column is disposed in the deep groove 120. The initial positioning of the deep groove 120 is combined with the precise positioning of the limiting column 110, so that the positioning of the bottom support sheet 300 on the upper surface of the platform 100 can be effectively realized, and the accuracy of the subsequent dispensing process operation is facilitated.

In order to prevent the malfunction or influence on the operation time caused by the mutual adhesion of the plurality of base sheets 300 when the base sheets 300 are taken and placed, thereby causing the extension of the operation cycle, a brush 400 for separating the plurality of base sheets is disposed on the side surface of the platform 100, the brush 400 includes a body 410 and bristles 420 disposed on the body 410, and two ends of the bristles 420 are respectively a fixed end 421 connected to the body 410 and a free end 422 partially disposed within one side edge of the deep groove 120. Thus, if a plurality of base sheets 300 adhered together are removed at the same time, the free ends 422 of the brush staples 420 sweep the base sheet 300 positioned below from the base sheets 300 adhered to each other in the process of taking up the base sheets 300, thereby separating the base sheets 300 adhered to each other. In order to achieve a better separation effect, the brushes 400 are respectively provided at left and right sides along the length direction of the platform 100.

As shown in fig. 1 and fig. 3, the dispensing device includes a glue flow pipe 510 and a dispensing opening 520 disposed at a distal end of the glue flow pipe 510, wherein an opening direction of the dispensing opening 520 faces an upper surface of the platform 100. In order to effectively control the supply amount of the glue solution at the glue dispensing port 520, a flow controller 530 is arranged on the glue flow pipeline 510. By the control of the flow controller 530, the flow of the glue solution flowing out from the glue dispensing port 520 can be just dropped on the bottom support sheet 300 at the position where the glue dispensing is required to be arranged, and the glue dispensing amount is suitable for one-time bonding, which is not too much or too little. Specifically, the pick-and-place device for placing the bottom support sheet 300 on the platform 100 and taking the bottom support sheet away from the platform 100 after dispensing comprises an adsorption mechanism arranged on the working part 200, the adsorption mechanism comprises a vacuum motor (not shown in the figure) and a negative pressure pipeline 610 which are connected, a suction cup 620 for picking and placing the bottom support sheet is arranged at the tail end of the negative pressure pipeline 610, and the opening direction of the suction cup 620 faces the upper surface of the platform 100. Because the bottom support sheet 300 is a thin sheet structure, and is a white plastic sheet with a certain thickness, a certain shape and holes, the adsorption force is too large, which can bring difficulty to the releasing action after dispensing, and the adsorption force is too small, which can not complete stable and continuous taking action. In order to control the magnitude of the suction force of the suction cup 620 conveniently, a vacuum degree controller 630 is arranged on the negative pressure pipeline 610, and the vacuum degree controller 630 can effectively control the negative pressure value of the suction cup 620. It should be noted that the flow controller 530 and the vacuum controller 630 are both commonly used controllers, and the detailed structure and operation principle thereof are not described herein again. In order to make the structure of the working unit 200 compact, the dispensing device and the pick-and-place device are integrally provided on the working unit 200.

As shown in fig. 4 and 5, based on the special shape of the base plate 300 and shown in fig. 2, the position-limiting columns 110 disposed on the platform 100 may include multiple sets of different shapes and sizes, and each set of position-limiting columns 110 having the same shape and size are symmetrically disposed on the platform 100. Specifically, in the embodiment shown in fig. 2, 4 and 5, the bottom blade 300 is shaped as a complete rectangle with four rounded corners, and a first notch 310 and a second notch 320 are opened on two long sides of the rectangle, wherein the length of the first notch 310 is smaller than the length of the second notch 320. The first notches 310 are respectively arranged at the positions close to the two ends of the base support piece 300, the second notches 320 are respectively arranged at the positions close to the middle part of the base support piece 300, and the arrangement positions of the first notches 310 and the second notches 320 on the base support piece 300 are symmetrically arranged no matter the arrangement positions are long edges of the base support piece 300 or short edges of the base support piece 300. In order to accurately position the bottom bracket piece 300 on the platform 100, the plurality of sets of positioning posts 110 are arranged at positions and in shapes and sizes corresponding to those of the first notch 310 and the second notch 320. Referring to fig. 5, the sheet body of the narrower bottom bracket sheet 300 with the second notches 320 formed on the long sides thereof is provided with a dispensing position 330, and the sheet body of the narrower bottom bracket sheet 300 with the first notches 310 near the ends of the two sides thereof is provided with an absorbing position 340 for taking and placing the suction cup 620 of the bottom bracket sheet 300. In addition, the round angle of the limiting column 110 is arranged, so that effective positioning of the base support sheet 300 is ensured, and the base support sheet 300 is prevented from being damaged due to collision with the limiting column in the taking and placing process.
