[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-9A CNC gantry milling machine for processing a battery tray is shown, comprising a frame 1, a slide rail 2 is installed on the top of the frame 1, a gantry 5 is slidably connected to the top of the slide rail 2, a drive motor 4 is installed on the front side of the gantry 5, a lead screw 8 is connected to the output end of the drive motor 4, a guide rail 7 is sleeved on the surface of the lead screw 8, a lifting cylinder 6 is connected to the top of the guide rail 7, a milling part 9 slidably connected to the surface of the guide rail 7 is connected to the output end of the lifting cylinder 6, a positioning plate 3 is installed on the top of the frame 1, and a right-angle The frame unit 13 and the positioning plate 3 are provided with a recess inside, and the inner wall of the recess is installed with symmetrically arranged rubber rollers 35 through bearings. The inside of the recess is slidably connected with a rack plate 38, and the bottom surface of the rack plate 38 is meshedly connected with a driving gear 33. A rotating rod 32 is installed through the inside of the driving gear 33, and the end of the rotating rod 32 is connected to a main bevel gear 34. The surfaces of the two rubber rollers 35 close to each other are connected with a linkage rod 36, and the surface of the linkage rod 36 is connected with an auxiliary bevel gear 37 meshed with the main bevel gear 34.

[0034] Specifically, before milling the battery tray, the gantry 5 can be moved horizontally by using the slide rail 2, and the lead screw 8 can be driven to rotate by the driving motor 4, thereby driving the guide rail 7 to move horizontally perpendicular to the slide rail 2, and at the same time, the milling part 9 is driven to move up and down inside the guide rail 7 by the lifting cylinder 6, so as to realize the switching of the three-dimensional coordinate position of the milling part 9 above the frame 1 to adjust the high-precision requirements of the milling operation;

[0035] After that, the tray is placed on the surface of the positioning plate 3 by using the suction cup and other lifting structures, and then the rotating rod 32 rotates in the forward direction, and the driving gear 33 drives the rack plate 38 to move in the direction of one of the borders of the right-angle frame unit 13. At the same time, the main bevel gear 34 on the surface of the rotating rod 32 drives the auxiliary bevel gear 37 to rotate under the action of meshing, thereby driving the linkage rod 36 to rotate, and the linkage rod 36 thereby drives the rubber roller 35 to rotate, driving the tray attached to the surface of the rubber roller 35 to move horizontally. In this state, the moving direction of the tray is perpendicular to the moving direction of the rack plate 38, thereby providing a biaxial force for the tray, so that the tray can be better and more tightly attached to the surface of the right-angle frame unit 13, thereby strengthening the positioning constraint effect on the tray.

[0036] A support block is installed on the top of the frame 1, and the top of the support block is fixedly connected to the four corners of the bottom of the positioning plate 3. A servo motor No. 10 located below the positioning plate 3 is installed on the top of the frame 1, and the output end of the servo motor No. 10 is connected to one end of the rotating rod 32.

[0037] Specifically, servo motor No. 10 provides torque support for the rotation of the rotating rod 32. In addition, the design of the support block can create a gap between the bottom of the positioning plate 3 and the top surface of the frame 1, which is convenient for the installation of servo motor No. 10 and avoids a high overlap between the top of the servo motor No. 10 and the positioning plate 3, thereby facilitating the normal deflection of the subsequent movable frame plate 131.

[0038] The right-angle frame unit 13 includes a fixed frame plate 132 fixedly connected to the surface of the positioning plate 3. A step groove 15 is provided on the top side surface of the positioning plate 3. A movable rotating rod is rotatably connected above the step groove 15. A movable frame plate 131 is fixed on the surface of the movable rotating rod. One end of the movable rotating rod is connected to the second servo motor 12.

[0039] Specifically, after the pallet is milled against the right-angle frame unit 13, unloading is required. At this time, the second servo motor 12 is started to drive the movable frame plate 131 to deflect, so that the top of the positioning plate 3 is unobstructed along the direction of travel of the pallet, which is convenient for unloading.

[0040] The surface of the positioning plate 3 is provided with symmetrically arranged receiving grooves 31 , and the receiving grooves 31 are slidably connected to the rack plate 38 , and the depth of the receiving grooves 31 is less than the thickness of the positioning plate 3 itself.

[0041] Specifically, the design of the accommodating groove 31 facilitates the rack plate 38 to slide therein, thereby driving the tray to move on the surface of the positioning plate 3 .

[0042] The top of the rack plate 38 is open, a rubber layer 381 is embedded in the top of the rack plate 38, a plurality of equally spaced magnetic blocks 382 are connected to the bottom of the rubber layer 381, and an electromagnetic layer that attracts the magnetic blocks 382 is installed inside the rack plate 38.

[0043] Specifically, the rubber layer 381 can make the bottom surface of the tray and the surface of the rack plate 38 have greater contact friction, thereby being able to better push the tray. In addition, when unloading is required, starting the electromagnetic layer can generate an attractive force between the electromagnetic layer and the magnetic block 382, ​​thereby causing the rubber layer 381 to be concave and deformed, reducing the contact area between the tray and the surface of the rack plate 38, and facilitating the detachment of the tray.

[0044] A plurality of suction cup members 14 are installed through the interior of the positioning disc 3 , the bottom of the suction cup member 14 is connected to a micro electric telescopic rod 11 , and the top of the suction cup member 14 is flush with the surface of the positioning disc 3 in an initial state.

[0045] Specifically, after the tray is close to the two frame surfaces of the right-angle frame unit 13, the micro electric telescopic rod 11 is started to lift the micro electric telescopic rod 11, so that the suction cup member 14 can be adsorbed and connected with the bottom surface of the tray, thereby strengthening the restraining and limiting effect of the tray.

[0046] Second implementation method:

[0047] Figure 10-11 , wherein the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: a notch 137 is provided on one side surface of the movable frame plate 131, an electromagnetic plate 134 is installed inside the movable frame plate 131, rollers 136 arranged in pairs are installed inside the movable frame plate 131, and the cross-sectional area of ​​the rollers 136 is not greater than the cross-sectional area of ​​the notch 137, each pair of rollers 136 is connected by a U-shaped magnetic bracket 135, and there is magnetic repulsion between the magnetic bracket 135 and the electromagnetic plate 134.

[0048] Specifically, after the No. 2 servo motor 12 is started, the movable frame plate 131 is deflected, and the electromagnetic plate 134 is started synchronously. The magnetic repulsion force generated causes the magnetic bracket 135 to move, and then drives the roller 136 to expose the inside of the notch 137 and protrude to the surface of the movable frame plate 131. At this time, the tray unloaded along the surface of the movable frame plate 131 can be accelerated to leave under the action of the roller 136.

[0049] A suspension bracket 133 is fixedly mounted on the top wall of the movable frame plate 131 , and the bottom of the suspension bracket 133 is slidably connected to the surface of the magnetic bracket 135 .

[0050] Specifically, the sliding connection method allows the magnetic bracket 135 to maintain the connection between the suspension bracket 133 and the magnetic bracket 135 when the electromagnetic plate 134 is activated, ensuring that the magnetic bracket 135 can continue to be suspended and supported by the suspension bracket 133 after being reset.

[0051] The second servo motor 12 is electrically connected to the electromagnetic plate 134 , and a single rotation angle of the second servo motor 12 is not less than 90°.

[0052] Specifically, the single rotation angle of the second servo motor 12 exceeds 90°, and then the movable frame plate 131 will be flush with the positioning plate 3 or form a slope with the surface of the positioning plate 3 after deflection, which is convenient for material unloading operation.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
