[0016] like Figures 1 to 4 As shown, the cam pole piece positioning device of the utility model includes a fixing component 1 that can be fixed to the whole battery manufacturing device, a baffle component 2 and a gear component 3 installed on the fixing component 1. The fixing component 1 includes a base plate 11 and a pole piece mold 12 fixed on the base plate 11; a baffle component 2 that can slide open and close is installed on the base plate 11, and the baffle component 2 includes a cross slot plate 25 located under the pole piece mold 12 and a baffle group that clamps the pole piece mold 12 therein, and a gear component 3 that can control the opening and closing of the baffle component 2 is provided. When operating, the baffle component 2 is opened and the pole piece is placed, and the baffle component 2 is closed and the placed pole piece is gathered to a fixed position, and the positioning of the pole piece is completed. The gear component 3 includes a circular gear 32 located at the bottom of the base plate 11, a spur gear group 33 and a circular positioning rotation groove 31 located between the pole piece mold 12 and the cross slot plate 25.

[0017] The pole piece mold 12 is a hollow plate with holes on the surface, and has through holes connected to the vacuum suction device. After the pole piece is positioned, it is adsorbed on the pole piece mold 12 to prevent movement, thereby ensuring accurate positioning.

[0018] like Figure 1 As shown, a base plate 11 is fixed on a frame of a battery manufacturing device. The base plate 11 is in the shape of a plate. A pole piece mold 12 is fixedly installed above the base plate 11. The pole piece mold 12 is replaceable and can be replaced with the same size as the pole piece to be used. The position of the pole piece mold 12 is the position where the pole piece needs to be positioned.

The four baffle groups slide on the cross-shaped groove 251; the cross center of the cross-grooved plate 25 is just below the pole piece mold 12. The four baffle groups surround the pole piece mold 12 therein, and after sliding inward, the four baffle groups closely surround the four sides of the pole piece mold 12, playing the role of positioning the pole piece.

[0020] The front baffle plate assembly 21 is located at the front part of the cross-shaped groove 251 , and includes a front slide rail 211 slidable in the cross-shaped groove 251 . A front vertical baffle plate 212 erected vertically is adjustably connected to the top surface of the front slide rail 211 .

[0021] The front slide rail 211 is in the shape of a plate, and a raised track is provided downwardly on the bottom surface of the front slide rail 211, which is just adapted to slide in the cross-shaped groove 251. The end surface of the front slide rail 211 close to the center of the cross-shaped groove 251 extends inward to form a front pulling portion 213 located in the groove, which is used to pull the front slide rail 211 to slide on the cross-shaped groove 251. The top surface of the inner end of the front pulling portion 213 is provided with an upwardly erected cylindrical front cam follower 214, which is trapped by the circular positioning groove 31 and is driven by the gear assembly 3 to pull the front slide rail 211.

[0022] The front vertical baffle plate 212 is a plate with an L-shaped vertical section. At least two through grooves extending inward and outward directions are provided on the horizontal side of the bottom of the front vertical baffle plate 212. It is screwed to the top surface of the front slide rail 211 by screws. The position of the front vertical baffle plate 212 can be adjusted by adjusting the position of the screw connection in the through groove. The vertical side of the front vertical baffle plate 212 is upright and can be close to the pole piece mold 12.

[0023] The rear baffle group 22, the left baffle group 23 and the right baffle group 24 have the same structure as the front baffle group 21, and all include slide rails and baffles, which are respectively located at the rear, left and right parts of the cross slot plate 25. The rear baffle group 22 includes a rear slide rail 221 and a rear baffle 222, which pull the rear pulling portion 223 and the rear cam follower 224 of the rear slide slot 221; the left baffle group 23 includes a left slide rail 231 and a left baffle 232, which pull the left pulling portion 233 and the left cam follower 234 of the left slide rail 231; the right baffle group 24 includes a right slide rail 241 and a right baffle 242, which pull the right pulling portion 243 and the right cam follower 244 of the right slide rail 241.

[0024] like Figure 3 and Figure 4 As shown, the gear assembly 3 includes a disc-shaped circular positioning groove 31 , a circular gear 32 close to the bottom surface of the bottom plate 11 , and a spur gear set 33 tooth-connected with the circular gear 32 .

[0025] The circular positioning rotating groove 31 is in the shape of a disc, and has four arc-shaped through grooves in the vertical direction, which are correspondingly sleeved on the front cam follower 214, the rear cam follower 224, the left cam follower 234 and the right cam follower 244. There are holes at the center point of the cross slot plate 25 and the position corresponding to the bottom plate 11. A shaft extends downward from the center of the circular positioning rotating groove 31, and the shaft passes through the cross slot plate 25 and the bottom plate 11 downward and is connected to the circular gear 32. The circular gear 32 is sleeved on the shaft, and the rotation of the circular gear 32 drives the circular positioning rotating groove 31 to rotate. After the circular positioning rotating groove 31 rotates, it drives the four cam followers to move in the arc slot, and then drives the four baffle groups to move.

[0026] The spur gear set 33 includes a straight rail 333 fixed to the bottom surface of the bottom plate 11, a spur gear slot plate 332 with a slot adapted to the straight rail 333, a spur gear 331 on the spur gear slot plate 332, and the spur gear 331 is toothed with the circular gear 32. The spur gear set 33 drives the circular gear 32 to rotate.

[0027] The straight rail 333 locates the moving direction of the spur gear slot plate 332; in order to locate the moving range of the spur gear slot plate 332, a positioning spring vertical plate 334 and a plug vertical plate 337 with a plug 336 installed are respectively erected on the bottom surface of the bottom plate 11 and the two ends of the spur gear slot plate 332.

[0028] The positioning spring vertical plate 334 extends a round stick toward the spur gear slot plate 332, and a spring 335 is sleeved on the round stick and then inserted into the spur gear slot plate 332; the plug vertical plate 337 extends a section toward the spur gear slot plate 332 to form a plug 336, and the plug 336 is made of a soft and elastic material. A connecting rod 338 is provided with one end connected to the spur gear slot plate 332, and the middle of the connecting rod 338 is fixed. When the other end is moved, the connecting rod 338 drives the spur gear slot plate 332 to move along the straight rail 333. The spur gear slot plate 332 is pressed toward the positioning spring vertical plate 334, and then released, so that the spur gear slot plate 332 moves to the plug 336 through the rebound force of the spring 335, and the plug 336 plays a buffering role.

[0029] The gear set 3 drives the baffle assembly 2 in the following manner: the connecting rod 338 is moved to press the spur gear slot plate 332 in the direction of the spring 335, so that the spur gear slot plate 332 drives the spur gear 331 to move, the spur gear 331 drives the circular gear 32 to rotate, the circular gear 32 drives the circular positioning groove 31 to rotate, and the rotation of the circular positioning groove 31 opens the front baffle group 21, the rear baffle group 22, the left baffle group 23 and the right baffle group 24 away from the pole piece mold 12; the connecting rod 338 is released, and the spring 335 bounces the spur gear slot plate 332, and finally the four baffle groups are close to the pole piece mold 12, and then the pole piece placed on the pole piece mold 12 is gathered to the correct position, which plays a positioning role.
