Description

Avoid damaging fork truck arm of lithium cell utmost point book
Technical Field
The invention relates to pole roll transfer equipment, in particular to a forklift arm for avoiding damaging a lithium battery pole roll.
Background
The pole roll of the lithium battery refers to a roll which is formed by coating battery slurry on a foil and winding the battery slurry on a roller, and the existing pole roll transportation in the market is realized by manually lifting an arm by a forklift operator and moving the forklift left and right, so that the forklift arm can rightly support two sides of a winding drum, the pole roll can be lifted up and down, and the pole roll can be circulated on equipment in different production workshops; the defect that in the production process of the pole roll, the pole roll is deviated or too wide frequently, so that the distance between a pole lug and the edge of a winding drum is short, different personnel have different proficiency on a forklift, the winding drum has a blind area due to too large pole roll, a forklift arm often collides with the pole lug in the transfer process of the pole roll, the pole roll is partially or wholly damaged and cannot be used, and more manufacturing cost is brought to enterprises; in addition, the damage of the tab can reduce the yield of the battery cell and increase the subsequent cost after sale. For example, the chinese patent literature discloses a novel forklift with a tray, whose publication number CN201395495 includes a cross beam connected with the forklift body, the end of the cross beam is provided with a tray, the tray is formed by a concave structure with the periphery facing inward, the utility model can effectively prevent the disadvantage of colliding and falling when loading and unloading electrode rolls; however, the disadvantage is that although the pole roll does not fall off in the moving direction of the forklift, the pole roll still deviates in the transportation process, so that the pole roll collides with the forklift arm, and the pole roll is partially or wholly damaged.
Disclosure of Invention
The invention provides a forklift arm capable of quickly detecting the distance between the inner side of the forklift arm and a pole lug and timely responding, aiming at overcoming the problem that the pole coil is damaged due to the fact that a blind zone exists when the pole coil is transported by a forklift in the prior art and a forklift arm often bumps the pole coil.
In order to achieve the purpose, the invention adopts the following technical scheme:
a forklift arm for avoiding damaging a lithium battery pole roll is specially used for supporting the fork arm of the pole roll, arc-shaped grooves are formed in the tail ends of the forklift arms, the extending direction of the arc-shaped grooves is perpendicular to the forklift arms, the distance between the forklift arms on two sides is matched with the length of a winding drum in the pole roll, distance measuring sensors are arranged on the inner sides of the forklift arms at the positions of the arc-shaped grooves and connected with a controller, and an alarm is further arranged on the forklift and connected with the controller; according to the invention, the distance measuring sensors on the two sides of the forklift arm are used for detecting the horizontal distance and the vertical distance between the forklift arm and the pole roll, when the distance is smaller than the set safe distance, the distance measuring sensors transmit signals to the controller, the controller transmits the signals to the alarm, and the alarm automatically gives an alarm to remind an operator of collision risk; the operating personnel readjusts the utmost point book for on the utmost point book is in safe position, and the transportation work is continued to be accomplished again, compares in prior art, has guaranteed when transporting the utmost point book, and the fork truck arm can not hurt the utmost point book's utmost point ear, controls the fork truck arm between range sensor's automatic alarm control device, can reduce the probability that the utmost point book was damaged, has improved the yield of battery again, can show the cost that reduces the enterprise.
Preferably, the lifting motor of the forklift arm is connected with the controller and is connected with the controller through the lifting motor, so that the controller can close the motor at the first time after receiving the instruction of the distance measuring sensor, the lifting operation of the forklift is stopped, the pole roll is protected from collision, and the lifting motor can normally work only when the pole roll is in a safe position and keeps a safe distance with the forklift arms on two sides.
Preferably, rubber pads are arranged on the inner sides of the forklift arms at the positions of the arc-shaped grooves; when the motor stopped, the utmost point book probably because inertial reason continues to remove, probably also can make utmost point book and arc wall bump to make the utmost point book by the damage, set up the rubber pad in the inside rubber pad in the both sides of arc wall, can play certain cushioning effect when bumping, protect extremely book to a certain extent, reduce the power of collision.
As preferred, all the adhesion is equipped with the lug on the reel of utmost point book both sides, the arc wall be equipped with the recess in the position that the lug corresponds, because forklift arm and utmost point book, accomplish the support to the utmost point book through the reel of utmost point book both sides, and the reel becomes cylindrically, can take place to rotate at the in-process of transportation, not only can make utmost point book position take place the skew when turning, if at an excessive speed, still can make utmost point book fall off from fork truck, the destruction degree to utmost point book is bigger, glue the lug on the reel to place in the recess, make utmost point book be difficult to take place to rotate, guarantee the stability of utmost point book in handling.
Preferably, the groove is a sliding groove on the arc-shaped surface of the arc-shaped groove, and the sliding groove extends from one side of the arc-shaped groove to the other side; the arrangement of the convex block and the groove mainly aims to ensure that the pole roll does not deviate in the turning process, the groove is arranged into a sliding groove, and the winding drum can rotate to a certain extent without deviating.
Preferably, the arc-shaped surface of the arc-shaped groove on one side of the forklift arm is provided with a surface thread, the outer sides of the winding drums on two sides of the pole roll are respectively provided with a sleeve, and one side of the sleeve with the surface thread is correspondingly provided with a sleeve thread; because the pole roll weight is not light, need lift up the pole roll and adjust when adjusting the pole roll, the adjustment is more laborious, sets up the sleeve in one side to set up the screw thread on sleeve and corresponding arc wall, the transport personnel only need rotate the sleeve and just can adjust the horizontal position of pole roll, accomplish the adjustment, and need not lift up the pole roll, made things convenient for the adjustment of pole roll.
Preferably, an elastic ring is adhered to the inner part of the sleeve; the sleeve is sleeved on the winding drum, the elastic ring can generate certain extrusion force to the winding drum, the winding drum can be rotated together when the sleeve is rotated, when the extrusion force is large enough, the winding drum and the sleeve cannot slide, and the winding drum cannot be damaged.
Preferably, the forklift arm is provided with a motor guide plate on the outer side of the side with the surface thread, the end part of the winding drum on the side with the surface thread is connected with a moving motor, the shaft of the moving motor is fixedly connected with the shaft of the winding drum, and the motor is arranged on the guide plate in a sliding manner; the motor sets up in the deflector, and when the motor took place to rotate, the sleeve drove the reel and inwards or outside activity under the cooperation of screw thread, and operating personnel can adjust the horizontal position of utmost point book through the positive and negative commentaries on classics of starter motor, and need not people manual operation for the adjustment is more convenient.
Therefore, the invention has the following beneficial effects: (1) the damage of a forklift arm to the pole roll in the pole roll transferring process is avoided; (2) when in use, the axial position of the pole roll can be automatically adjusted; (3) the yield of the battery core manufacturing is improved, and the cost is saved.
