Description of the drawings:
FIG. 1 is a schematic diagram of the system of the present invention.
FIG. 2 is a control flow of the programmable controller of the present invention.
The specific implementation mode is as follows:
the invention is further illustrated below with reference to fig. 1:
the design idea of the invention is to adopt a non-mechanical contact type separation mode, utilize the rigidity characteristic of the bar block, when the adhesive tape stuck with the bar block is bent at an angle close to 180 degrees, the adhesive tape can be naturally separated from the adhesive tape, and simultaneously utilize an air medium to apply a further separation acting force to an element, thus the separation function can be safely and efficiently completed.
Based on the above design concept, the specific embodiment of the present invention includes the following steps:
as shown in fig. 1, a transfer tape is first selected, and the transfer tape must have an adhesive function, so that the transfer tape 3 in this embodiment is a transfer tape with an adhesive on the upper surface.
The conveying system is arranged for realizing the basic task of the invention and consists of a motor, a constant tension control device, a winding expansion shaft, an unwinding expansion shaft, a plurality of groups of rollers, a knife edge plate, an air curtain mechanism above the knife edge plate and a conveying adhesive tape. The motor directly controls and drives the winding expansion shaft to realize the transmission of the transmission rubber belt. The power transmission sequence is as follows: the motor 106 and the winding expansion shaft 10 gradually retract the transmission adhesive tape on the unwinding expansion shaft 2 by the winding expansion shaft, so that the displacement of the transmission adhesive tape is realized.
The UV adhesive tape for bonding the diced upper surface with the diced particles 20 is characterized in that a vacuum sucker 5 is fixed under a mechanical arm 101, the vacuum sucker is attached with the UV adhesive tape 7 with the diced particles, the UV adhesive tape is moved to a supporting platform 4 positioned below a transmission belt through the mechanical arm, and the supporting platform 4 and a guide wheel 1 for supporting the transmission adhesive tape can be provided with a frame and fixed on the frame. And then pressing the UV adhesive tape down onto the transmission adhesive tape 3 above the supporting platform to enable the back surface of the UV adhesive tape to be tightly attached to the transmission adhesive tape, and lifting the UV adhesive tape after the negative pressure is removed by the vacuum chuck. In this embodiment, the particles are ceramic particles.
The motor of the conveying system is started to drive the winding expansion shaft 10 to enable the transmission adhesive tape to move forwards slowly, the UV adhesive tape with the particles of the bar blocks firstly passes through a UV curing furnace 102 arranged on the conveying system to be irradiated by a UV lamp 18, the adhesive force of the UV adhesive tape is reduced, then the UV adhesive tape with the particles of the bar blocks 20 firstly passes through a gap between a first turning guide roller 15 and a pressing roller 8 to complete 90-degree bending, and then the UV adhesive tape passes through a second turning guide roller 16 to complete second 90-degree bending, so that one side of the particles of the bar blocks attached to the UV adhesive tape is changed from upward to downward. The transmission adhesive tape drives the UV adhesive tape attached with the particles to move to the tool tip of the knife edge plate 9, and the constant tension control device controls the transmission adhesive tape to cling to the guide roller and the knife edge plate to complete bending of nearly 180 degrees. The constant tension control device can adopt the combination of the constant tension controller 105 and the magnetic powder brake 103, which is beneficial to ensuring that the transmission adhesive tape runs under the state of certain tension and friction force. In order to realize the 180-degree bending, a fixed-angle guide wheel 17 is arranged behind the knife edge plate 9, the fixed-angle guide wheel 17 is almost parallel to the second turning guide roller 16, and due to the 180-degree bending and the high hardness of the particles of the barns, the bending action cannot be finished, so that part of the particles of the barns are directly separated from the UV adhesive tape and fall into a material tray. However, due to the action of the adhesive, a part of the bar particles still adhere to the UV adhesive tape and are in a half-detached state.
In the embodiment, the air curtain mechanism comprises a high-speed fan, a narrow-slit type air supply outlet and an air valve for controlling the air supply rhythm. And opening an air valve of the air curtain mechanism, wherein an air outlet 14 of the air curtain mechanism is arranged above the knife tip of the knife edge plate 9, and high-speed airflow is sent out from the air outlet 14 of the air curtain mechanism and blown to the semi-separated particles of the bars, so that the front ends of the semi-separated particles of the bars 13 are lifted and fall into the material tray 11. The transfer tape with the UV tape applied thereto is wound on the winding expansion shaft 10 and then can be detached. In order to control the falling range of the barlock particles, a baffle plate 12 can be arranged in the material tray 11.
In this embodiment, in order to realize full automation of the present invention, a programmable controller is adopted to control operation of the motor and the air curtain mechanism, and the operation of the mechanical arm is matched, so that when the mechanical arm finishes grabbing of a next UV adhesive tape pasted with particles of a block, a pasting position is just left on the transmission adhesive tape, then the PLC controller 104 controls the motor 106 to stop operation, the mechanical arm is pressed downwards and lifted after pressing, and the PLC controller controls the motor to continue to operate.
The motor of the invention can be a variable frequency motor.
The control flow of the PLC controller is shown generally in fig. 2.
