Description

Technical Field

[0001] This utility model relates to the field of coated battery string technology, and in particular to a film supply device. Background Technology

[0002] In a type of coated battery string, a film is used to fix the solder strip to the battery cell on both the front and back sides, or only the back side. In the production of the above-mentioned coated battery strings, the string bonding machine prepares the film required for the battery string by setting a film supply mechanism.

[0003] In related technologies, such as Figure 1 As shown, the film supply mechanism includes a sleeve and a film roll located at the drive end of the sleeve, so that the sleeve drives the film roll to rotate and output. The film forming mechanism adjacent to the film supply mechanism includes a transmission group and a film pulling hand. The film pulling hand can clamp the film strip output from the film roll to facilitate the preparation of film sheets. The transmission group is located between the film supply mechanism and the film pulling hand. The counterweight in the transmission group can move up and down. The film strip output from the film roll is wrapped and contacted with the transmission group. The counterweight can not only extend the buffer of the film strip, but also avoid the risk of breakage caused by the film pulling hand directly pulling the film. Because the film roll is affected by the temperature of the battery string welding machine, the film strip is prone to sticking to the film roll. When outputting the film strip, the fixed wheel of the transmission group is higher than the film roll, and cannot provide sufficient traction force for the film strip to peel off the film roll. As a result, the film strip cannot peel off the film roll in time, and the film strip is rolled back onto the film roll. Utility Model Content

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0027] As shown in Figures 2 to 4 The present application discloses a film supply device, the disclosed film supply device includes a base 100, a shaft seat 200, a sleeve 300, a roller driving assembly 400, a driven roller 500 and a lifting stopper 600, the base 100 can provide a mounting basis for the shaft seat 200, the roller driving assembly 400 and the lifting stopper 600.

[0028] Specifically, the sleeve 300 is rotatably arranged on the shaft seat 200, the shaft seat 200 is liftably arranged on the base 100, the sleeve 300 can be lifted with the shaft seat 200 relative to the base 100, the roller driving assembly 400 and the lifting abutting piece 600 are both arranged on the base 100, the roller driving assembly 400 supports and can drive the film roll arranged on the sleeve 300 to rotate, the driven roller 500 is adjacent to the film roll and is connected in transmission with the roller driving assembly 400, the driven roller 500 is arranged opposite to the supporting end of the lifting abutting piece 600, the output film strip of the film roll passes between the driven roller 500 and the supporting piece, and the driven roller 500 and the lifting abutting piece 600 are both in abutment with the output film strip of the film roll, and the rotation direction of the driven roller 500 is consistent with the rotation direction of the film roll.

[0029] In the use of the film supply device, the sleeve 300 is arranged with the film roll, since the shaft seat 200 is liftably arranged on the base 100, the roller driving assembly 400 always supports the film roll arranged on the sleeve 300 and drives the film roll to rotate, the output film strip of the film roll continuously moves between the driven roller 500 and the lifting abutting piece 600, since the driven roller 500 is connected in transmission with the roller driving assembly 400, the roller driving assembly 400 drives the driven roller 500 to rotate, the output end of the film roll also moves with the rotation of the driven roller 500, and since the driven roller 500 and the supporting end of the lifting abutting piece 600 are both in abutment with the output film strip of the film roll, the driven roller 500 and the supporting end of the lifting abutting piece 600 exert clamping force on the output film strip of the film roll, so that the part of the output film strip of the film roll adjacent to the film roll can be peeled off, thereby avoiding the occurrence of reverse winding or unsmooth peeling.

[0030] In the above structure, by arranging the roller driving assembly 400, the driven roller 500 and the lifting abutting piece 600, the position of the film roll driven by the driving force is shifted from the center of the related art to the edge, the driven roller 500 and the supporting end of the lifting abutting piece 600 exert clamping force on the output film strip of the film roll in the output process, thereby avoiding the output film strip of the film roll from adhering to the film roll, so that the output film strip can be timely peeled off from the film roll, and the subsequent process of the battery string is ensured not to be affected.

[0031] In an optional scheme, the lifting abutting piece 600 can be a supporting arc-shaped protruding piece, the arc-shaped protruding piece is elastically connected with the base 100, the circular arc protrusion of the arc-shaped protruding piece is arranged opposite to the driven roller 500, and the circular arc protrusion and the driven roller 500 are both in linear contact with the output film strip, the friction force is small, which is beneficial to the smoothness of the movement of the output film strip; in another optional scheme, the lifting abutting piece 600 can include a telescopic air cylinder 610 and a rotating roller 620, specifically, the telescopic air cylinder 610 is arranged on the base 100, and the rotating roller 620 is rotatably arranged on the driving end of the telescopic air cylinder 610.

[0032] The structure drives the extension of the driving end of the telescopic cylinder 610, and the driven roller 500 and the rotating roller 620 abut against the output film belt of the film roll. When the film roll is replaced with a new one, the telescopic cylinder 610 drives the retraction of the driving end thereof, the rotating roller 620 is away from the driven roller 500, and a large gap is formed between the two, facilitating manual film threading by the staff.

[0033] In a further technical solution, the outer wall of the rotating roller 620 can be provided with an anti-sticking layer, so as to avoid the output film belt from sticking to the rotating roller 620 due to long-time frictional contact with the rotating roller 620. The anti-sticking layer can be a silica gel layer, a Teflon layer, etc., and the present application does not make any limitation in this regard.

[0034] In a further technical solution, the lifting abutting member 600 can further include a spring. Specifically, a guide rod is slidingly arranged on the driving end of the telescopic cylinder 610, the rotating roller 620 is rotatably arranged on the guide rod, and the spring is sleeved on the guide rod, with the two ends of the spring abutting against the end face of the driving end of the telescopic cylinder 610 and the guide rod, respectively.

[0039] Of course, in the above structure, the transmission cooperation of the first roller 430 and the second roller 440 and the transmission cooperation of the other one of the first roller 430 and the second roller 440 with the driven roller 500 can all adopt synchronous belt transmission, gear transmission and chain transmission, etc., and the present application does not make any limitation on this.

[0040] In a further technical solution, the diameter of the driven roller 500 can be greater than the diameter of any one of the first roller 430 and the second roller 440, so as to not only increase the contact area between the driven roller 500 and the output film belt, but also, under the condition of the same angular velocity, make the linear velocity of the driven roller 500 faster than the rotational speed of any one of the first roller 430 and the second roller 440, so as to ensure that the film belt between the first roller 430 and the second roller 440 adjacent to the driven roller 500 in the output film belt is taut, thereby ensuring that the output film belt is better peeled off from the film roll, and further avoiding that the output film belt is rolled back on the film roll.
