Description

Device for automatically grabbing lithium battery material sagger

Technical Field

The invention relates to the technical field of carrying equipment, in particular to a device for automatically grabbing a lithium battery material sagger.

Background

The bulk raw materials of the lithium battery materials are pressed into a block-shaped green body after being filled into a sagger, and then the block-shaped green body is taken out and sent into a kiln for high-temperature firing. The sagger depth for loading lithium battery material is high, typically 150 to 180 mm. At present, in the production process of the sagger, the stuffing is filled in a mould manually, and the sagger is taken out manually after the pressing is finished.

Because the sagger edge is higher, if demolding and blank taking (i.e. sagger) are required, the clear height between the upper die and the lower die is required to be larger than the height of the sagger, and if the sagger is 180 mm high, the clear height between the upper die and the lower die is required to be about 200 mm. If the automatic sucking disc is used for taking the blank, the thickness of the sucking disc and the space height reserved for the sucking disc to safely enter and exit are added to the net height value, and if the thickness of the sucking disc is 80 mm, the safety distance of 10 mm is added to the upper and lower parts, the net height value is about 300 mm. In this case, the stroke of the master cylinder provided on the press for preparing the sagger needs to be increased by 100 mm. This reduces the speed and increases the power of the press hydraulic system, making it impossible to produce sagger efficiently and at low cost.

The conveying direction of the conveying line 110 may be in the X direction or the Y direction, and the conveying line 110 may be a belt conveyor, a roller conveyor, or the like. The tray mechanism removes the sagger 300 from the press 200, and then places the sagger 300 on the transfer line 110, so that the transfer line 110 transfers the sagger 300.

As shown in fig. 1 and 6, the sagger 300 is prepared using the conventional press 200, and after filling is completed, the sagger 300 is pressed using the upper mold 210, the lower mold 220, and the floating frame 240. After the pressing is completed, the upper mold 210 moves upward, the side cores 230 eject the sagger 300 upward, and the floating frame 240 moves downward, so that the sagger 300 is exposed.

Assuming that in the conventional press 200 the net height between the upper die 210 and the lower die 220 is 200mm, the sagger 300 is 180 mm high.

The device 100 for automatically gripping lithium battery material sagger is then used to remove sagger 300 from press 200.

During the operation of the device 100 for automatically gripping the sagger of the lithium battery material, the suction cup frame 130 is driven by the second driving device to move to the right to the upper position of the sagger 300; then, under the driving of the first driving device, the suction cup frame 130 moves down with the suction cup 131, the sagger 300 is sucked by the suction cup 131, and then, the first driving device drives the suction cup frame 130 to move up, so that the suction cup 131 drives the sagger 300 to move up by a certain height, such as 20mm, at this time, the suction cup 131 is at a certain distance from the upper die 210, so that the suction cup 131 can move left and leave the press 200 conveniently, and the sagger 300 cannot move horizontally due to the obstruction of the lower die 220.

Subsequently, the tray mechanism is activated. The tray frame 140 is moved to the right under the sagger 300 by the fourth driving means, and since the supporting members 141 are provided at both front and rear sides of the tray frame 140, the supporting members 141 are not blocked by the lower mold 220 (i.e., the distance between the supporting members 141 at both sides of the tray frame 140 is greater than the width of the lower mold 220) when the supporting members 141 move under the sagger along with the tray frame 140, and at this time, the supporting members 141 are respectively positioned under the front end portion and the rear end portion of the sagger 300. Then, the suction cup 131 releases the suction effect on the sagger 300, releases the sagger 300, and moves left and away from the press 200 by the driving of the second driving means. At the same time, the sagger 300 falls on the support 141, and a strong supporting effect is provided by the support 141.

Then, the third driving means drives the tray frame 140 to move upward, and lifts the sagger 300 to a certain height by using the supporting member 141, at this time, the sagger 300 is completely separated from the lower mold 220 (i.e., the bottom surface of the sagger 300 is higher than the top surface of the lower mold 220), and the top surface of the sagger 300 is spaced from the upper mold 210 by a certain distance, so that the sagger 300 can be conveniently moved horizontally and separated from the press 200. Next, the fourth driving means drives the tray frame 140 to move to the left, and the sagger 300 is taken out from the press 200 through the support 141, thereby completing one shot of the blank taking operation.

Finally, the supporting member 141 places the sagger 300 on the transfer line 110 by the third driving means.

Through the organic cooperation of tray mechanism and sucking disc mechanism, sucking disc mechanism makes sagger 300 rise a take the altitude, makes things convenient for tray mechanism's support 141 to can remove to the below of sagger 300, exerts the supporting role, and the reuse tray mechanism is lifted sagger 300 in order to break away from lower mould 220 to take sagger 300 horizontal migration, accomplishes the work of sagger 300 uninstallation from press 200.

The device 100 for automatically grabbing the sagger of the lithium battery material adopts the unique structure, so that the sagger 300 is automatically and efficiently taken out from the press 200, the problems of high labor intensity and high cost in the existing press unloading mode are well solved, the press 200 can be prevented from being modified, and the stroke of the press 200 is increased to complete the sucker blank taking task.

While the preferred embodiment of the present application has been described in detail, the application is not limited to the embodiments, and various equivalent modifications and substitutions can be made by those skilled in the art without departing from the spirit of the application, and these modifications and substitutions are intended to be included in the scope of the present application as defined in the appended claims.
