Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In the manufacturing process of the battery cell, the battery cell needs to be coated, and the purpose of the coating is to seal the battery cell, prevent electrolyte leakage, and simultaneously play a role in insulation and protection. In the high-automation battery cell forming machine, when the battery cell coating is finished, a rubberizing mechanism directly seals the membrane edges at two sides, and meanwhile, in order to ensure the sealing effect, an edge sealing for protecting an inner rubberizing position is reserved during edge cutting, so that rubberizing is ensured not to overflow. However, if the reserved sealing edge is not processed, the appearance is not only affected, but also the battery area is increased, and the sealing edge is unfavorable for adapting to various products, so that the sealing edge of the battery cell coating needs to be renovated through a shaping mechanism.
As shown in fig. 1, the present invention provides a cell edge banding trimming forming apparatus comprising a rail 10. The slide rail 10 is a production transportation line, and the battery cells to be treated are conveyed to each processing mechanism through the slide rail 10, so that the battery cells are produced in an integrated pipelined manner. In order to facilitate the transportation of the battery cell, a battery cell clamp 20 which is matched with the slide rail 10 and moves synchronously is arranged on the slide rail 10. The battery cell clamp 20 comprises an upper clamping plate, a lower clamping plate and a locking mechanism, and when in use, the battery cell is clamped between the upper clamping plate and the lower clamping plate and is transported along the advancing direction of the slide rail 10 after being locked by the locking mechanism. Meanwhile, a glue dropping mechanism 30, a vertical binding mechanism 40, a hot stamping mechanism 50 and a cold stamping shaping mechanism 60 are sequentially arranged outside the slide rail 10.
In one embodiment of the invention, shown in fig. 2, the single-folded cell edge seal is formed by trimming, and the slide rail 10 is an annular slide rail. The entire rail 10 is a sealed ring-like shape with no absolute start and end points. In this way, the whole equipment is operated without arranging a manipulator or a transfer device, and the edge sealing and trimming forming process of one cell is completed in one process under the clamping of one cell clamp 20. After one cell process is completed, the cell fixture 20 can immediately enter the next cell process for continuous operation.
In order to meet the production requirement, the annular slide rail is divided into a forward straight line section 11, a steering section 12, a reverse straight line section 13 and an upper and lower material section 14 which are sequentially connected end to end. The forward straight line segment 11 and the backward straight line segment 13 are arranged in parallel and opposite, and the forward straight line segment 11 and the backward straight line segment 13 have opposite advancing directions due to two backward tracks with one sliding rail changing backward. The outer sides of the forward straight line section 11 and the backward straight line section 13 are respectively provided with a glue dripping mechanism 30, a vertical edging mechanism 40, a hot stamping mechanism 50 and a cold stamping shaping mechanism 60, and the two glue dripping mechanisms 30, the vertical edging mechanism 40, the hot stamping mechanism 50 and the cold stamping shaping mechanism 60 are sequentially arranged along the advancing direction of the corresponding tracks. The turning section 12 and the feeding and discharging section 14 are respectively connected with two ends of the forward straight line section 11 and the backward straight line section 13, the turning section 12 is connected with the output end of the forward straight line section 11 and the input end of the backward straight line section 13, and the feeding and discharging section 14 is connected with the input end of the forward straight line section 11 and the output end of the backward straight line section 13. Meanwhile, the steering section 12 is provided with a steering mechanism 1 which can assist the steering of the cell clamp 20, so that the unfinished side edge of the cell clamped in the cell clamp 20 faces to mechanisms outside the other section of the sliding rail 10. And the feeding and discharging end 14 is provided with a feeding mechanism 2 and a discharging mechanism 3, which are correspondingly used for placing the battery cells to be processed in the battery cell clamp 20 and taking off the battery cells after being shaped. When the electric core trimming and trimming device is used, in the upper and lower material feeding sections 14, the material feeding mechanism 2 clamps an electric core to be processed after trimming into an electric core clamp 20 according to the position requirement, the sliding rail 10 moves forwards to drive the electric core clamp 20 to enter the straight line section 11, and the electric core edge sealing exposed outside the straight line section 11 can sequentially pass through the glue dripping mechanism 30, the vertical edge rolling mechanism 40, the hot stamping mechanism 50 and the cold stamping shaping mechanism 60 to realize single-side edge sealing and trimming molding. The battery core clamp 20 enters the steering section 12, the steering mechanism 1 assists the steering of the battery core clamp 20, so that the edge sealing of the other side of the battery core clamped by the steering mechanism faces to all mechanisms outside the retrograde straight line section 13, and then the battery core clamp passes through another set of glue dripping mechanism 30, vertical edge rolling mechanism 40, hot stamping mechanism 50 and cold stamping shaping mechanism 60 outside the retrograde straight line section 13 to realize double-side trimming and shaping.
The glue dropping mechanism 30 is used for dropping glue on the edge sealing of the battery cell, and after glue dropping, the edge sealing can be better attached to the battery cell, so that the battery is not easy to drop and the use of the battery is not affected. The traditional glue dripping equipment is provided with an adjusting mechanism nearby in a plurality of matching ways, the position of the battery is adjusted firstly, the battery is guaranteed to be positioned at an accurate glue dripping position, a sensor is arranged at the glue dripping position, and glue is always dripped on the inner side of the edge sealing and cannot overflow when glue is dripped. The device formed by combining the multiple devices has complicated electrical control and difficult investigation when the devices are in fault. The glue dropping mechanism 30 adopted by the invention comprises a glue dropping servo cylinder 31 and a glue outlet cylinder 32, wherein the glue outlet cylinder 32 is arranged on the glue dropping servo cylinder 31, and the glue dropping servo cylinder 31 is in driving connection with the glue outlet cylinder 32. The glue dispensing quantity can be precisely controlled through the glue dispensing servo cylinder 31, and on the other hand, the movement track of the glue dispensing cylinder 32 can be precisely controlled through the glue dispensing servo cylinder 31, so that the glue dispensing cylinder can move along the edge sealing of the battery in a straight line, and the glue dispensing is rapid, accurate and fixed-point quantitative.
The vertical hemming mechanism 40 includes a mounting bracket 41, a slide plate 42, and a lateral cylinder 43 and a longitudinal cylinder 44 mounted on the slide plate 42. The mounting 41 is used to support the entire mechanism. A vertical rail is provided on the mounting frame 41 with the up-down direction shown in fig. 1, and the slide plate 42 is slidably connected to the mounting frame 41 through the rail. A longitudinal cylinder 44 is provided at the lower end of the slide plate 42 to drive the slide plate 42 to slide up and down along the mounting frame 41. That is, the slide plate 42 can be moved up and down in the vertical direction by the driving of the longitudinal cylinder 44. The transverse cylinder 43 is arranged at the upper end of the sliding plate 42, a roller 45 is connected to the output end of the transverse cylinder 43, and the roller 45 faces the sliding rail 10, namely the battery cell edge sealing. Because the edge of the battery cell is not square, the arc is formed due to the production and process requirements, and the edge of the roller 45 rolls, compared with the traditional method of using a roller to push and press, the edge of the battery cell is folded by 180 degrees and then folded by 90 degrees, so that the edge sealing of the battery cell envelope can be better and tightly attached. When the edge rolling machine is used, the roller 45 is pushed forwards towards the sliding rail 10, namely the battery cell direction, so that extrusion force is generated through the transverse air cylinder 43, the edge sealing is ensured to be always clung to the edge of the battery cell when edge rolling is performed, and finally, the edge folding is flattened.
The hot stamping mechanism 50 can melt the glue in the folded edge through the hot stamping plate, so that the glue can bond the sealed edge and the battery cell more uniformly, and the cold stamping shaping mechanism 60 cools and fixes the glue after the sealed edge is folded, so that the trimming effect of the whole battery is ensured. In order to meet the production requirements, a plurality of ironing mechanisms 50 and cold ironing shaping mechanisms 60 can be arranged on the production line at the same time.
The cell forming effect of the single folded edge is shown in fig. 4.

(5) Reversing and trimming: the electric core after cold ironing and shaping is clamped by an electric core clamp 20, enters a reversing section 12 along a sliding rail 10, and a steering mechanism 1 drives the electric core clamp 20 to reverse, so that the edge sealing of the other side of the clamped electric core which is not processed faces to all mechanisms outside a retrograde straight line section 13, and then enters the retrograde straight line section 13 to sequentially perform glue dripping, edge folding and hot melting and cold setting;
(6) And (3) blanking: leaving the retrograde straight section 13, the cell clamp 20 moves the cell back to the loading and unloading section 14 along the slide rail 10, the unloading mechanism 3 takes off the finished cell at the current station, and the loading mechanism 2 puts the next semi-finished cell into the cell clamp 20 to start a new round of refurbishment.
In summary, when the slide rail 10 is suspended at a fixed point, the most ideal, efficient and relatively energy-saving situation is that all the battery core clamps 20 on the slide rail 10 are stopped just before one mechanism, and the mechanism at least comprises a steering mechanism 1, a feeding mechanism 2, a discharging mechanism 3, a glue dropping mechanism 30, a vertical binding mechanism 40, a hot stamping mechanism 50 and a cold stamping shaping mechanism 60. That is, when one cell fixture 20 is stopped at the glue dispensing mechanism 30, the immediately preceding cell fixture 20 closest thereto may be stopped at the vertical trimming mechanism 40 at the same time, and the immediately following cell fixture 20 closest thereto may be stopped at the feeding mechanism 2 at the same time. Thus, the whole production line can realize high-efficiency continuous operation. The high-automation production can be realized by only predefining the position and operation parameters of each mechanism according to the moving speed of the slide rail 10. Of course, when the number of the operated cell clamps 20 is less than the number of the mechanisms, that is, there are idle mechanisms, or there are idle cell clamps 20, the sensors are needed to be matched at each mechanism, so that the mechanism can be started only when the clamp clamping the cell is in place, and the design is more humanized.
In the original production process, the vertical trimming mechanism 40 is used as a shaping mechanism, and the folded edge is shaped further after hot melting and cold setting, so that the edge sealing is reinforced. That is, in the original process, the outer side of the slide rail 10 is sequentially provided with a glue dropping mechanism 30, a double-edge rolling mechanism, a hot stamping mechanism 50, a cold stamping and trimming mechanism 60 and a vertical edge rolling mechanism 40. When in use, the glue dropping mechanism 30 drops glue on the edge sealing firstly, and then folds the edge via the folding and rolling mechanism (at this time, the single folded cell is easy to leave wavy lines due to the thin edge sealing, so as to influence the sealing effect). After the edge is folded, the edge is fixed through the hot stamping mechanism 50 and the cold stamping shaping mechanism 60, and finally the edge is shaped by the vertical edge rolling mechanism 40. Since the folding and trimming mechanism is easy to leave the wavy lines, and finally when the vertical trimming mechanism 40 is shaped, the wavy edges are attached together, so that gaps are easy to leave, and hidden danger exists. In the process of the invention, the vertical binding mechanism 40 is directly arranged in front to replace the double-edge binding mechanism, so that on one hand, the requirement of single edge folding is more satisfied, and on the other hand, the position of the double-edge binding mechanism can be vacated for placing the CCD detection device 4, and the requirement of the modern technology is more satisfied.
In another embodiment of the present invention, as shown in fig. 3, a primary flanging assembly line is further connected to the front end of the original production line for the cells requiring two flanging. Through a primary flanging assembly line, the battery cell edge sealing can be folded and flanged by 180 degrees, and then the battery cell edge sealing enters the production line in the previous embodiment, and is called a secondary flanging assembly line at the moment, so that the laminating and flanging are realized.
The primary flanging assembly line and the secondary flanging assembly line form a whole set of production line through the annular sliding rail. Likewise, the annular slide rail also comprises a forward straight line section 11, a steering section 12, a reverse straight line section 13 and an upper and lower material section 14. Only one set of flanging system and one set of edging system are respectively arranged at one time outside the forward straight line section 11 and the backward straight line section 13. The trimming system is the same as the previous embodiment and includes a glue dispensing mechanism 30, a vertical trimming mechanism 40, a blanching mechanism 50, and a cold wave trimming mechanism 60. The hemming system is similar to the hemming system and also includes a glue dispensing mechanism 30', a blanching mechanism 50' and a cold wave trimming mechanism 60', except that the vertical hemming mechanism 40 for conforming to the hemming is replaced with a conventional hemming roller 70. The folding roller 70 comprises an upper arc roller 71 and a lower plane roller 72 (in the prior art), and can fold the edge of the battery cell in half by matching the arc roller 71 with the plane roller 72, thereby realizing folding. After the folded battery is subjected to hot stamping and cold stamping, and the fixed edge sealing, the folded battery enters a binding system, and the process flow of the previous embodiment is the same, so that the folded edge rolling is realized, and finally the edge sealing is completely attached to the edge of the battery.
In summary, the trimming and forming effect of the folded cell is shown in fig. 5.
The cell shaping process of the cell double-flanging forming production line shown in fig. 3 comprises the following steps:
(1) And (3) transmitting: in the loading and unloading section 14 of the slide rail 10, the loading mechanism 2 clamps the semi-finished product battery core after trimming in the battery core clamp 20, so that the sealing edges of the packaging film of the battery core are stretched out from two sides of the battery core clamp 20, namely the sealing edges of the battery core are exposed outwards, and the battery core is convenient to repair by all mechanisms; the battery core clamp 20 clamps the battery core to be conveyed forwards along the slide rail 10 and enters the forward straight line section 11;
(2) Forward one-sided one-fold: in the forward straight line section 11, the battery core clamp 20 clamps the battery core to sequentially pass through the glue dripping mechanism 30', the folding roller 70, the hot stamping mechanism 50' and the cold stamping shaping mechanism 60' of the folding system along the sliding rail 10, and the edge sealing of the battery core is folded in half and fixed by glue dripping;
(3) Forward one-side two-edge folding: after one flanging, the battery core fixture 20 clamps the battery core to sequentially pass through the glue dripping mechanism 30, the vertical trimming mechanism 40, the hot stamping mechanism 50 and the cold stamping shaping mechanism 60 of the trimming system along the slide rail 10, and the folded edge is bonded and trimming is carried out along the edge of the battery core and fixed, so that the edge of the battery core is completely bonded on the edge of the battery core;
(4) Reversing flanging: after the two folds, the battery core clamp 20 clamps the battery core along the slide rail 10 to enter the reversing section 12, the steering mechanism 1 drives the battery core clamp 20 to reverse, so that the edge sealing of the untreated other side of the clamped battery core faces to each mechanism outside the retrograde straight line section 13, and then enters the retrograde straight line section 13 to sequentially perform a folding operation and a folding operation;
(5) And (3) blanking: and leaving the retrograde straight line section 13, moving the battery core back to the loading and unloading section 14 by the battery core clamp 20 along the sliding rail 10, taking down the finished battery core at the current station by the unloading mechanism 3, putting the next semi-finished battery core into the battery core clamp 20 by the loading mechanism 2, and starting a new round of trimming.
Of course, for convenience of use, the production line can simultaneously satisfy two process modes of single flanging and flanging, as shown in fig. 3, in the middle of the annular slide rail, a loading and unloading section 14 'is further arranged behind the primary flanging assembly line (cold ironing shaping mechanism 60') when seen from the advancing direction of the forward straight line section 11. The forward straight line section 11, the steering section 12, the reverse straight line section 13 and the feeding and discharging section 14' form a short process for single flanging. On the short-process straight-line segment 13 for single folding, a folding roller 70 is reserved, and a vertical edge rolling mechanism 40 is also arranged. When used as a two-fold cell line, the folding roller 70 operates and the vertical trimming mechanism 40 is not activated, only as a point in the line flow of the rail 10. When used as a single-folded cell line, the folding roller 70 is not activated and the vertical hemming mechanism 40 operates to satisfy both process modes.
The invention can realize uninterrupted and continuous battery trimming molding through the annular slide rail, and has high automation level. The sliding rail cooperates with each mechanism to pause at fixed points, so that the multi-station high-efficiency operation can be realized at the same time, and the production efficiency is high.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative, not restrictive, and many changes may be made by those having ordinary skill in the art without departing from the spirit of the present invention and the scope of the appended claims, which are to be construed as falling within the scope of the present invention.
