[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 9 As shown, the present invention provides a vehicle battery shell processing device, including a guiding mechanism 1, a positioning and clamping mechanism 2, a welding mechanism 3 and a gluing mechanism 4.

[0036] The positioning and clamping mechanism 2 includes a positioning plate 201 horizontally slidably mounted on the guide mechanism 1, an L-shaped positioning block 202 mounted on the positioning plate 201 for limiting the positions of the frames 30 of the lower shell 10, and a side pressure piece 203 for fixing the frames 30 and a suction cup piece 204 for sucking the bottom plate 20 from the bottom to position and press the bottom plate 20 against the frames 30. Specifically:

[0039] The welding mechanism 3 includes a lifting plate 301 that can move up and down relative to each other, and an upper welding head 302 and a lower welding head 303 that can face the welding part of the lower shell 10 are arranged on the two lifting plates 301. Specifically:

[0040] The two lifting plates 301 are driven to move upward and downward toward each other by a power assembly, and the power assembly includes a third rack 304 vertically connected to the bottom of the upper lifting plate 301 and a fourth rack 305 vertically connected to the top of the lower lifting plate 301. The relative inner walls of the third rack 304 and the fourth rack 305 are meshed with the two side walls of the third gear 307 fixed in the middle and driven by the motor 306.

The second gluing head 402 can contact the first gluing head 401 during the rotation of the rotating assembly 403, but a gap is maintained between the two at the time of contact, so as to avoid interference between the two and ensure gluing.

[0042] The inside of the glue cylinder 404 is slidably mounted with a piston 405 which divides the glue cylinder 404 into a first glue injection chamber 406 and a second glue injection chamber 407. The second glue injection head 402 is connected to the second glue injection chamber 407 via a glue outlet pipe. The first glue injection chamber 406 and the second glue injection chamber 407 are both connected to a glue tank 418 via a glue inlet pipe. The glue outlet pipe is provided with a one-way glue outlet valve (not shown in the figure), and the glue inlet pipe is provided with a one-way glue inlet valve (not shown in the figure).

[0043] The first glue head 401 is connected to the first glue injection cavity 406 through a glue outlet pipe, and the lifting plate 301 is connected to the rotating assembly 403, the piston 405 and the positioning plate 201 through a power mechanism.

[0044] The power mechanism includes a ratchet mechanism 214 fixedly arranged on one side of the welding part, a second rack 207 vertically connected to the lifting plate 301 above, a piston rod 409 and a guide rod 419. During the lifting process of the second rack 207, the second gear 208 mounted on the swing rod 210 and the swing shaft 209 of the ratchet mechanism 214 is driven to rotate alternately forward and reversely. The ratchet 211 of the ratchet mechanism 214 is coaxially mounted with a first gear 206. The first gear 206 is meshed with a first rack 205 arranged below the positioning plate 201 and parallel to the guide rail 101 of the guide mechanism 1. The piston rod 409 is vertically connected above the piston 405. The rotating assembly 403 includes It includes a turntable 408 and a rotating drum 410 coaxially arranged with the second rotating shaft 414 of the turntable 408, the second gluing head 402 is installed at an eccentric position of the bottom of the turntable 408, and the distance between the axis of the second gluing head 402 and the rotating shaft of the turntable 408 is equivalent to the radius of the arc groove 21, the outer wall of the rotating drum 410 is provided with spiral grooves 411 connected end to end, and a vertical guide groove 412 is also provided parallel to the rotating shaft direction of the rotating drum 410, a slider 413 is slidably installed inside the vertical guide groove 412, and a shift block 415 that can slide along the spiral groove 411 is provided on the inner side of the slider 413, and the upper end of the slider 413 is connected to the guide rod 419.

[0045] Furthermore, in order to make the glue diameter continuous, a plug 416 that can be locked with the rubber cylinder 404 by a locking piece (not shown in the figure) is slidably installed above the piston 405 in the rubber cylinder 404. The plug 416 is connected to the top of the rubber cylinder 404 by a return spring 417, and the piston rod 409 slides through the plug 416. When the piston 405 contacts the surface of the plug 416, the locking piece unlocks the plug 416.

[0046] The working principle of the device of the present invention is:

[0047] 1. Positioning and clamping the lower shell:

[0048] When the positioning plate 201 is located at one side of the welding mechanism 3, each frame 30 of the lower housing 10 is positioned outside the L-shaped positioning block 202 to enclose it into a frame shape. Afterwards, each side pressure piece 203 is activated to press and fix each frame 30 positioned relative to the L-shaped positioning block 202.

[0049] Then, the bottom plate 20 of the lower housing 10 is positioned and placed on top of each positioned frame 30 , and the suction cup member 204 is activated to suck and press the bottom plate 20 onto the frame 30 from below.

[0050] 2. Position adjustment:

[0051] Afterwards, the positioning plate 201 is pushed sideways along the guide rail 101, so that the first rack 205 and the first gear 206 below the positioning plate 201 are meshed with each other, and the upper welding head 302 is aligned with the first spot welding position between the lower frame 30 and the bottom plate 20;

[0052] 3. Welding Processing:

[0053] Afterwards, the upper welding head 302 and the lower welding head 303 on the two lifting plates 301 are driven to move toward each other and away from each other alternately. When the upper welding head 302 and the lower welding head 303 move toward each other, the upper welding head 302 and the lower welding head 303 press the frame 30 and the bottom plate 20 and perform spot welding therebetween. This process is called the "first stroke". When the spot welding is completed, when the upper welding head 302 and the lower welding head 303 move away from each other, the upper welding head 302 and the lower welding head 303 both withdraw from the surface of the frame 30 and the bottom plate 20 and return to their initial state. This process is called the "second stroke".

[0054] In the "first run": the positioning plate 201 and the lower housing 10 positioned thereon are fixed in position, refer to Figure 8 The above picture and Fig. 9 (F), it should be noted that, Fig. 9 The reference point a in the figure is the intersection of a straight edge 22 on the bottom plate 20 and the end of the adjacent arc groove 21, so as to serve as a reference for the overall movement of the lower shell 10 with the positioning plate 201. The first glue injection cavity 406 absorbs glue from the glue box 418, and the glue in the second glue injection cavity 407 is glued along the arc groove 21 on the bottom plate 20 during the rotation of the turntable 408, so that the arc groove 21 on the bottom plate 20 and the pressed edge of the frame 30 are sealed; specifically:

[0055] When the upper lifting plate 301 is pressed down, the second rack 207 connected to the lifting plate 301 drives the second gear 208 and the rocker arm 210 coaxially mounted with the second gear 208 to rotate around the rocker shaft 209. During the rotation, since the ratchet 211 is limited by the non-return pawl (not shown in the figure), the active pawl 213 connected to the rocker arm 210 will slide relative to the surface of the ratchet 211. The ratchet 211 and the first gear 206 coaxially mounted thereon will not drive the positioning plate 201 where the first rack 205 is located to move, that is, the lower shell 10 on the positioning plate 201 is in a relatively static state.

[0056] When the upper lifting plate 301 is pressed down, the piston rod 409 connected to the lifting plate 301 will press the piston 405 down along the rubber cylinder 404, and the volume of the first glue injection chamber 406 will increase, forming a negative pressure therein, thereby sucking the glue in the glue box into the first glue injection chamber 406; while the volume of the second glue injection chamber 407 is reduced, and the glue therein is squeezed to the second glue head 402 for extrusion.

[0057] And no matter whether the lifting plate 301 is rising or pressing down, the guide rod 419 connected to the lifting plate 301 will drive the slider 413 to reciprocate vertically along the vertical guide groove 412. During the movement, the shift block 415 on the slider 413 will move along the spiral groove 411 of the rotating drum 410, thereby driving the rotating drum 410 where the spiral groove 411 is located to rotate continuously in one direction. In the "first movement", the second glue head 402 on the turntable 408 connected to the second rotating shaft 414 of the rotating drum 410 applies glue in a circular shape from the arc head of an arc groove 21 to the tail.

[0058] In the Second Journey, see Figure 8 The following figure and Fig. 9 When the positioning plate 201 and the lower shell 10 thereon move a distance of the width of a straight edge 22 and its adjacent arc groove 21, the second glue injection cavity 407 sucks glue from the glue box 418, and the second glue head 402 stops glueing but keeps rotating; and the first glue injection cavity 406 has two different states during this operation: State 1: the lower shell 10 moves a distance of a straight edge 22, and the volume of the first glue injection cavity 406 is compressed, and the first glue injection cavity 406 glues along the straight edge 22 on the bottom plate 20, so that the straight edge 22 on the bottom plate 20 and the frame 30 are pressed together and sealed; State 2: the lower shell 10 further moves a distance of the width of the arc groove 21, and the first glue injection cavity 406 stops glueing. The principle is as follows:

[0059] When the lifting plate 301 at the top is rising, the second rack 207 connected to the lifting plate 301 drives the second gear 208 and the swing rod 210 coaxially mounted with the second gear 208 to rotate in the opposite direction around the swing shaft 209. During the rotation, since the ratchet 211 is no longer limited by the non-return pawl, the active pawl 213 on the swing rod 210 drives the ratchet 211 to rotate, and the ratchet 211 and the first gear 206 coaxially mounted thereon drive the positioning plate 201 where the first rack 205 is located to move by the width of an arc groove 21 and the distance of the adjacent straight edge 22;

[0060] In state 1, while the lifting plate 301 at the top is rising, the piston rod 409 connected to the lifting plate 301 will make the piston 405 rise along the rubber cylinder 404, and the volume of the second glue injection chamber 407 will increase, forming a negative pressure therein, thereby sucking the glue in the glue box 418 into the second glue injection chamber 407; while the volume of the first glue injection chamber 406 is reduced, and the glue in it is squeezed to the first glue head 401 and squeezed out. Fig. 9 In (D), the straight edge 22 moving with the positioning plate 201 is coated with glue in a straight line. When the glue is coated to the tail section of the straight edge 22, the state 2 is entered. The piston 405 contacts the pressure plug 416, triggering the locking member to unlock, so that the piston 405 and the pressure plug 416 are moved up along the rubber cylinder 404 and the return spring 417 is compressed. At this time, the first glue injection cavity 406 is hollow, and the glue is seen. Fig. 9In the middle (E), when the arc-shaped groove 21 moves from below the first glue-spraying head 401 , glue is not injected in the width direction of the arc-shaped groove 21 .

[0061] In the "second operation", the second glue head 402 connected to the turntable 408 of the second rotating shaft 414 of the rotating drum 410 rotates idly around the other side of the arc that can form a circle with the arc groove 21, avoiding glue injection during the movement of the lower shell 10. This cycle is repeated until the subsequent spot welding and glue sealing of the boundary position are completed.

[0062] The present invention cooperates among the guiding mechanism 1, the positioning and clamping mechanism 2, the welding mechanism 3 and the gluing mechanism 4 so that when the welding mechanism 3 spot-welds the bottom plate 20 and the frame 30 of the lower shell 10, in the process of switching between the "first operation" and the "second operation", it automatically and synchronously completes the switching of the next spot welding position and the staggered gluing of the arc groove 21 and the straight edge 22 at the edge of the bottom plate 20, so that the gluing process is uniform, continuous and efficient, and the above process can also automatically realize the automatic alternating glue replacement and gluing operations of each glue cavity of the glue cylinder 404, which improves the overall accuracy and efficiency of welding and gluing sealing of the lower shell 10 with the arc groove 21 and the straight edge 22.

[0063] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
