At the same time, in the description of the present invention, directional terms and order terms are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] like Figures 1-2 As shown, the precise unloading device of the laser scribing machine comprises a workbench 4, a product transmission line 2 for conveying products, a unloading box 6 for loading products, an unloading box conveying line 5 for conveying the unloading box, an unloading and conveying mechanism 1 for conveying products on the product transmission line 2 to the precise unloading mechanism 3, and a precise unloading mechanism 3 for receiving products from the unloading and conveying mechanism 1 and aligning them in the unloading box 6. The unloading and conveying mechanism 1 is installed on a bracket 7, and the bracket 7 is fixed on the workbench. The product transmission line 2 and the unloading box conveying line 5 are located below the movement track of the unloading and conveying mechanism 1.

[0034] like Figures 3 to 5As shown, the precise unloading mechanism 3 includes a support plate lifting and tilting mechanism 31 and a retaining edge mechanism 32, wherein the support plate lifting and tilting mechanism 31 includes a Z-axis electric cylinder 311 on which a fixed bracket 310 is installed, a lifting connection component 312 is installed on the driving rod of the Z-axis electric cylinder 311, and a guide shaft 313 is installed on the lifting connection component 312, and the guide shaft 313 passes through a guide hole on the fixed bracket 310, and a lifting guide linear bearing is installed in the guide hole, and the driving rod of the Z-axis electric cylinder 311 is drivingly connected to the guide shaft 313 to drive it to move up and down, and a support is installed on the top of the guide shaft 313 Support plate 317, one end of the suction cup connecting plate 316 is hinged to the support plate 317 through a pin shaft 318, the lifting cylinder 314 is fixed on the support plate 317, the piston rod of the cylinder 314 is connected to one end of the suction cup connecting plate 316, the piston rod of the cylinder 314 can drive the suction cup connecting plate 316 to rotate and tilt around the pin shaft 318; a negative pressure suction cup is installed on the suction cup connecting plate 316, the adsorption support plate 315 is placed on the suction cup connecting plate 316, and an avoidance hole is opened on the adsorption support plate 315 at a position corresponding to the negative pressure suction cup, and the negative pressure suction cup extends out of the adsorption support plate 315 through the avoidance hole.

[0035] When the driving rod of the Z-axis electric cylinder 311 is extended and retracted, the guide shaft 313 on the lifting connection assembly 312 drives the adsorption support plate 315 and the suction cup connecting plate 316 to rise or fall along the lifting guide linear bearing; the adsorption support plate 315 can pass through the through hole on the material box bottom plate 61 to lift the material box support plate 62 and receive the products delivered by the unloading and conveying mechanism 1.

[0036] The piston rod of the lifting cylinder 314 extends out, and the suction cup connecting plate 316 rotates around the pin shaft 318, so that the suction cup connecting plate 316 tilts at an angle; the piston rod of the lifting cylinder 314 retracts, and the suction cup connecting plate 316 returns to a horizontal position.

[0037] The side guard mechanism 32 includes a Y-axis displacement adjustment plate 329 and a fixing member 326 installed thereon, a rotating shaft 324 is installed on the Y-axis displacement adjustment plate 329, a lower portion of the side guard 325 is installed on the rotating shaft 324, and an upper portion is connected to the side guard connecting plate 322 via a cam 323, a piston rod of a side guard tilting cylinder 321 is drivingly connected to the side guard connecting plate 322, and can drive the side guard 325 to rotate and tilt around the rotating shaft 324, and the side guard 325 is L-shaped; the Y-axis displacement adjustment plate 329 is installed on an X-axis displacement adjustment plate 327, and can adjust its position along the Y-axis relative to the X-axis displacement adjustment plate 327, the X-axis displacement adjustment plate 327 is installed on a fixed base plate 328, and the X-axis displacement adjustment plate 327 can adjust its position along the X-axis relative to the fixed base plate 328, thereby adjusting the working position of the side guard mechanism 32 in the X-direction and the Y-direction.

[0038] The retaining edge mechanism 32 is installed on the column and is located at a height above the material box 6. The height can ensure that the retaining edge 325 will not touch the material box when it is inclined at a certain angle.

[0039] When the piston rod of the rib tilting cylinder 321 is extended, the L-shaped rib 325 is in a horizontal state. When the piston rod of the rib tilting cylinder 321 is retracted, the rib 325 is driven to rotate around the rotating shaft 324 to tilt at an angle.

[0040] An air flow nozzle 9 is arranged beside the retaining mechanism 32. Figure 7 The airflow nozzle 9 faces the retaining edge 325 . When the products fall one by one onto the bottom plate of the loading box of the adsorption support plate 315 , the airflow force causes the products to stick to the two sides of the L-shaped retaining edge 325 .

[0041] The material unloading and conveying mechanism 1 comprises a linear motion module 114, a vacuum adsorption component 10 and a vacuum adsorption component 2 11. The linear motion module 114 is mounted on the bracket 7. A rotating unit 12 is provided on the linear motion module 114. A lifting unit 13 is provided on the rotating unit 12. The vacuum adsorption component 10 and the vacuum adsorption component 2 11 are installed on the lifting unit 13. The vacuum adsorption component 10 and the vacuum adsorption component 2 11 are arranged in a straight line, one on the left and one on the right. The rotating unit 12 drives them to rotate, and the product is transferred from the product transmission line 2 to the top of the precise unloading mechanism 3.

[0042] like Figure 6 As shown, the material box 6 includes a material box bottom plate 61 and a material box baffle 63 upright thereon, and the material box baffle 63 is arranged in a quadrilateral form to form an open space for accommodating products, and a through hole is opened on the material box bottom plate 61 of the accommodating space for the pallet lifting and tilting mechanism 31 of the precise material unloading mechanism 3 to pass through when rising and falling, and a material box pallet 62 is arranged in the accommodating space for the pallet lifting and tilting mechanism 31 to hold up.

[0043] The material box conveyor line 5 includes two side conveyor belts 50 for carrying the material boxes and a material box blocking rod 51 arranged at the front end thereof for blocking and positioning the material boxes. Both sides of the conveyor belt 50 are provided with material box baffles 52 for restricting the running direction of the material boxes. There is a hollow area between the two side conveyor belts. The material boxes are placed on the two side conveyor belts and fed forward. After feeding into place, the adsorption support plate 315 passes through the through hole on the material box bottom plate 61 of the material box 6, and adsorbs and supports the material box support plate 62 to rise.

[0044] The material box 6 is constrained and limited in its running direction by the material box baffles 52 on both sides on the material box conveyor line 5. When it moves forward to the position of the material box baffle rod 51, the first material box stops, and the second material box stops when it hits the first material box, thereby achieving the positioning effect of the material box on the conveyor line.

[0045] In specific applications, the battery cells are transferred from the front end to the bottom of the unloading and handling mechanism 1 via the product transmission line 2. The lifting unit 13 of the unloading and handling mechanism 1 descends to drive the vacuum adsorption component 10 to suck up the battery cells. The lifting unit 13 rises, and the synchronous rotating unit 12 drives the vacuum adsorption component 10 and the vacuum adsorption component 2 11 to rotate. The vacuum adsorption component 10 transfers the sucked battery cells to the top of the precise unloading mechanism 3, and the vacuum adsorption component 2 11 then sucks up the battery cells transmitted from the product transmission line 2.

[0046] The driving rod of the Z-axis electric cylinder 311 of the support plate lifting and tilting mechanism 31 of the precise unloading mechanism 3 is extended, driving the lifting connection assembly 312 and the guide shaft 313 to move upward, and the adsorption support plate 315 and the suction cup connecting plate 316 are raised. The adsorption support plate 315 passes through the through hole on the material box bottom plate 61 of the unloading box 6 and is about to approach the bottom of the material box support plate 62. The negative pressure suction cup on the suction cup connecting plate 316 opens and continues to move upward. The negative pressure suction cup adsorbs the material box support plate 62. After the adsorption support plate 315 contacts the material box support plate 62, it drives the material box support plate 62 to rise. When the material box support plate 62 rises to the set position under the lifting action of the Z-axis electric cylinder 311, the position slightly exceeds the height of the material box baffle 63, and ensures that after the material box support plate 62 is tilted at a certain angle, the lowest point of the material box support plate 62 is still higher than the material box baffle 63;

[0047] The piston rod of the side guard tilting cylinder 321 retracts, causing the L-shaped side guard 325 to tilt at an angle (10°~20°), the piston rod of the lifting cylinder 314 extends out, and the suction cup connecting plate 316 rotates around the pin shaft 318, causing the suction cup connecting plate 316 to tilt at an angle, and the material box support plate 62 rotates at the same angle driven by it to form an inclined dustpan storage structure, and begins to store the battery cells 8 dropped from the vacuum adsorption component 10. After it is full, the unloading and conveying mechanism 1 moves horizontally to the right side. At this time, the piston rod of the lifting cylinder 314 retracts, the suction cup connecting plate 316 returns to a horizontal position, and the material box support plate 62 also returns to a horizontal state at the same time, the piston rod of the side guard tilting cylinder 321 extends out, and the L-shaped side guard 325 returns to a horizontal state. In this process, the L-shaped side guard 325 uses its L-shaped side to align the entire stack of battery cells.

[0048] The driving rod of the Z-axis electric cylinder 311 retracts, driving the lifting connection assembly 312 and the guide shaft 313 to move downward, the adsorption support plate 315 and the suction cup connecting plate 316 descend, and the material box support plate 62 drives the whole stack of battery cells to descend. When it comes into contact with the material box bottom plate 61, the vacuum of the negative pressure suction cup is closed, and the Z-axis electric cylinder is reset to the origin. The whole stack of battery cells is released and stored in the unloading box 6, and then the unloading box with the whole stack of battery cells is transported to the unloading station by the conveyor line.

[0049] To sum up, the present invention has a unique design and novel structure, and can automatically and precisely drop battery cells into the loading box of the stringer. The product (battery cells) is transported by the product transmission line, and the unloading and handling mechanism transfers the product on the product transmission line to the precise unloading mechanism. The precise unloading mechanism receives the product from the unloading and handling mechanism and stacks it. The whole stack of battery cells is released and stored in the unloading box, and the conveyor line transports the unloading box with the stack of battery cells to the unloading station. The laser scribing machine can directly use the loading box of the stringer when unloading, thereby solving the problem that the loading box of the stringer and the unloading box of the laser scribing machine are common.

[0050] It significantly reduces manual involvement and greatly saves labor costs, while avoiding the possibility of battery cells being damaged during transportation, thereby improving product quality.
