The photoelectric sensor is installed at the end of the transmission line 1, and the grabbing and transferring mechanism is triggered after detecting the battery piece in-place. The structure realizes the continuous feeding and discharging of the battery piece through closed-loop control, avoiding manual intervention.

[0033] Ring guide rail 2 is arranged outside the transmission line 1 to form a closed-loop motion path;

[0034] In the utility model, the ring guide rail 2 is driven by a servo motor and connected to the mover platform mechanism 3 through a synchronous belt, realizing the continuous circular motion of the mover platform on the ring path.

[0035] It should be noted that the ring guide rail 2 is a closed-loop track structure, and the mover platform mechanism 3 is driven by a servo motor to drive the synchronous pulley system to move circularly. Each mover platform is connected to the guide rail through a slider at the bottom and a vacuum adsorption platform is arranged above, and the battery piece is fixed by the negative pressure adsorption controlled by the electromagnetic valve. When the mover platform moves to the inkjet station, the vacuum adsorption is started to keep the battery piece stable.

In this way, the 10 mover platforms are seamlessly connected through the continuous motion of the guide rail, the transmission efficiency is improved compared with the traditional linear motor, and there is no risk of mechanical interference.

[0036] Mover platform mechanism 3 is slidably connected to the ring guide rail 2 for carrying and continuously transmitting the battery piece;

[0037] In the utility model, the mover platform mechanism 3 is provided with a plurality of mover platforms, which are evenly distributed along the closed-loop path of the ring guide rail 2. Each mover platform mechanism 3 includes a vacuum adsorption platform and a servo drive module for accurately controlling the position of the battery piece.

[0038] The ink jet mechanism 4 is arranged at the printing station of the annular guide rail 2, and is used for performing ink jet operation on the battery piece on the mover carrier mechanism 3.

[0040] It should be noted that the ink jet mechanism 4 is installed on the adjustable support through the slide rail and the ball screw, the servo motor at the bottom of the support drives the screw to rotate, and the ink jet head is lifted in the Z-axis direction. When the battery pieces (0.2-1.2mm) of different thicknesses enter the ink jet station, the laser ranging sensor feeds back the height data, and the ink jet head is automatically adjusted to the optimal ink jet distance of 1mm from the surface of the battery piece under the control of the PLC.

[0041] The transfer mechanism is respectively located at the feeding end and the discharging end of the annular guide rail 2, and is used for transferring the battery piece from the transmission line 1 to the mover carrier mechanism 3 and transferring the battery piece after ink jet to the transmission line 1.

[0043] It should be noted that the transfer mechanism 5 adopts the flexible clamping jaw 8 driven by the air pressure, the clamping jaw is made of silica gel material, the hollow structure in the inside expands to wrap the edge of the battery piece when the air is inflated, and the clamping jaw is released when the air is released. The clamping jaw arm moves in X-Y-Z three axes through the linear module, and the side edge of the battery piece is clamped with 0.5N soft pressure when the battery piece is grabbed, so that the ink jet surface is avoided to be contacted. The coordinated action of the mechanism and the mover carrier vacuum adsorption is controlled by the PLC, the grabbing error is reduced, the pressure mark caused by the traditional suction cup is completely eliminated, and the yield is improved.

[0044] The positioning structure includes the battery piece carrier plate 6 and the positioning mechanism 7, is used for multi-directional positioning of the battery piece on the mover carrier mechanism 3, and the positioning mechanism 7 is respectively located at the X-axis positive and negative directions and the Y-axis positive and negative directions of the battery piece carrier plate 6.

[0046] In the utility model, the surface of the battery piece carrier plate 6 is provided with anti-skid texture, and the edge of the carrier plate is provided with a guide groove, which cooperates with the push rod of the positioning mechanism 7, so that the battery piece is centrally positioned.

The surface of the carrier plate is provided with anti-skid texture, and the edge is processed with V-shaped guide groove. The push rods of the four positioning mechanisms 7 respectively extend from the positive and negative directions of the X / Y axis, and the front ends of the push rods are embedded in the guide groove to push the battery piece to the center of the carrier plate at a fixed speed. During the positioning process, the PLC controls the stroke of the cylinder according to the photoelectric signal, and the synchronous action of the four-way push rod makes the battery piece centered, so as to improve the positioning accuracy and reduce the positioning time compared with the traditional suction cup + visual correction scheme.

[0050] It should be noted that the control system takes the PLC as the core, obtains the position signal of the sub-carrier platform on the ring guide rail 2 in real time through the encoder, and synchronously coordinates the action timing of the grabbing and transferring mechanism, the positioning structure and the ink jet mechanism 4. For example, when the sub-carrier platform 1-1 moves to the ink jet station, the PLC triggers the ink jet head to start. At the same time, the next sub-carrier platform 1-2 reaches the feeding station, and the grabbing mechanism immediately performs the feeding operation. This multi-thread control improves the equipment utilization rate, shortens the beat time, and realizes real uninterrupted continuous production.

[0051] When the utility model is used, each sub-carrier platform is engaged with the synchronous pulley system driven by the servo motor through the slider at the bottom, the vacuum adsorption platform at the top starts negative pressure to fix the battery piece when moving to the ink jet station, and releases the negative pressure at the feeding and discharging stations so that the flexible clamping jaw 8 can be grabbed. The feeding transmission line 1 sends the battery piece to the end by the servo motor driven belt, the photoelectric sensor triggers the pneumatic silica gel clamping jaw to move through the linear module three-axis to grab the side edge of the battery piece, and moves to the sub-carrier platform at a soft pressure of 0.5N. The battery piece on the carrier platform is embedded in the V-shaped guide groove of the carrier plate by the four sets of cylinder driven push rods to be centrally positioned synchronously, then the sub-carrier platform moves to below the ink jet mechanism 4 along the ring guide rail 2, the laser ranging sensor feeds back the thickness data to the PLC to control the ink jet head to be adjusted to a height of 1mm away from the battery piece by the ball screw to print, the sub-carrier platform circulates to the discharging end after the ink jet is completed, the flexible clamping jaw 8 moves the finished product to the discharging transmission line 1, and the PLC synchronously coordinates the position signals of multiple sub-carriers to realize seamless beat connection, so as to improve the overall transmission efficiency and the yield.
