Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments.

Referring first to FIGS. 1 and 2 , FIG. 1 shows a photovoltaic cell formed from a plurality of cell strings 10 laid out. Specifically, referring to FIG. 2 , the battery string 10 is composed of a plurality of battery pieces 11 , and the plurality of battery pieces 11 are connected by welding strips 12 ; at both ends of the battery string 10 , the welding strips 12 protrude; 2a connects the welding strips 12 between multiple groups of battery strings 10 to realize bus flow; in the multiple groups of battery strings 10 connected to the same first type of bus bar 2a, there is also a second type of bus bar 2b between adjacent two groups of battery strings 10 ; One end of the second bus bar 2b is connected to the first bus bar 2a at one end of the battery string 10, and the other end is connected to the junction box to realize current flow.

It should be noted that "multiple groups of battery strings 10 connected to the same first type of bus bar 2a" are used as a group of battery strings 10 for description. Referring to FIG. 2 , in a group of battery strings 10 , since both ends of each battery string 10 have welding strips 12 protruding, it is necessary to configure two first-type bus bars 2 a to connect the welding strips 12 protruding from the same side end of each battery string 10 . Band 12. At the same time, since the two first-type bus bars 2a both need to be connected to the junction box, between any two adjacent battery strings 10 in a group of battery strings 10, two second-type bus bars 2b can be arranged to connect respectively A first type bus bar 2a.

Referring specifically to FIG. 1 or FIG. 2 , the two second-type bus bars 2b between two adjacent battery strings 10 are each connected to one of the first-type bus bars 2a at one end, and the other end faces the other first-type bus-bar The bar 2a is extended; at the same time, one end extending toward the other first type bus bar 2a is lifted upwards so as to facilitate the connection of the junction box.

Referring to FIGS. 3 to 15 , the present application discloses an integrated bus bar hot-pressing machine, which is characterized by comprising: an insulating film feeding device 100 for supplying the insulating film 1 ; a bus bar feeding device 200 for supplying the insulating film 1 ; Supply bus bar 2; material receiving device 300, material receiving device 300 includes material receiving platform 310 and material receiving driving component 320; material receiving driving component 320 is connected to material receiving platform 310, and can drive material receiving platform 310 on the insulating film feeding device 100 and the bus bar feeding device 200; the hot pressing device 400, the hot pressing device 400 includes a heating mechanism 410 and a hot pressing driving component 420; the hot pressing driving component 420 is connected to the heating mechanism 410 and can drive the heating mechanism 410 towards The material platform 310 moves.

Wherein, the material receiving platform 310 can move to the insulating film feeding device 100 to receive the insulating film 1 under the driving of the material receiving driving component 320, and then move to the bus bar feeding device 200 to receive the bus bar 2; The driving assembly 420 can drive the heating mechanism 410 to be close to the material receiving platform 310 to perform hot pressing, so that the bus bar 2 and the insulating film 1 are bonded together.

In one embodiment, the insulating film feeding device 100 may be a handling device, such as a manipulator or a crane, which can directly transport the finished insulating film 1 onto the feeding platform 310 . Similarly, the bus bar feeding device 200 can also be a similar conveying device. At this time, the finished insulating film 1 and the finished bus bar 2 are materials that meet specifications and can be directly hot-pressed. After being transported to the material receiving platform 310 , the hot-pressing device 400 can directly hot-press both.

It should be added that when the insulating film feeding device 100 and the bus bar feeding device 200 are handling devices, the feeding device 300 may only include the feeding platform 310; that is, when feeding, the feeding platform 310 may be fixed Without moving, the insulating film feeding device 100 and the bus bar feeding device 200 sequentially transport the insulating film 1 and the bus bar 2 to the receiving platform 310 . After the material is in place, the hot-pressing driving component 420 drives the heating mechanism 410 to move toward the material receiving platform 310 to hot-press the material.

Of course, the splicing device 300 may also include a splicing platform 310 and a splicing drive assembly 320. In this case, the splicing platform 310 has at least two working stations - an insulating film feeding station and a bus bar feeding station. In a working cycle, the splicing drive assembly 320 can drive the splicing platform 310 to move to the insulating film feeding station, waiting for the insulating film feeding device 100 to transport the finished insulating film 1 to the splicing platform 310; the splicing drive assembly 320 It is also possible to drive the material receiving platform 310 to move to the bus bar loading station, and wait for the bus bar loading device 200 to transport the finished bus bar 2 to the material receiving platform 310 .

It should be explained that in the material loading process, the material receiving platform 310 can first receive the insulating film 1 and then the bus bar 2; or, the material receiving platform 310 can first receive the bus bar 2 and then the insulating film 1; Whether the bus bar 2 is placed on the insulating film 1 or the insulating film 1 is placed on the bus bar 2 does not affect the hot pressing by the hot pressing device 400 . As long as the bus bar 2 can be adhered to the insulating film 1, the integrated bus bar heat pressing machine of the present application does not specifically limit the stacking method of materials, that is, the sequence of loading materials.

It should also be explained that, when the insulating film feeding device 100 and/or the bus bar feeding device 200 are handling devices, the feeding device 300 may include a feeding platform 310 and a feeding driving assembly 320 . At this time, the splicing drive assembly 320 can drive the splicing platform 310 to move to the insulating film feeding station, so that the insulating film feeding device 100 can transport the finished insulating film 1 onto the splicing platform 310; the splicing driving assembly 320 can also The material receiving platform 310 is driven to move to the bus bar loading station, so that the bus bar loading device 200 can transport the finished bus bar 2 onto the material receiving platform 310 .

In addition, for the hot pressing device 400, its main body can be fixedly set. After the feeding is completed, the feeding platform 310 is driven by the feeding driving component 320 to move to the hot pressing station corresponding to the hot pressing device 400. So that the hot pressing device 400 can realize hot pressing of the material.

Alternatively, the hot pressing device 400 further includes a hot pressing moving mechanism (not shown), the hot pressing moving mechanism is connected to the heating mechanism 410 and can drive the heating mechanism 410 to move to the hot pressing station. Specifically, after the material loading is completed, the material receiving driving component 320 drives the material receiving platform 310 to move to the hot pressing station (or, when the material receiving platform 310 is not moving, the basic station fixed by the material receiving platform 310 is the hot pressing station) At the same time, the hot-pressing moving mechanism drives the heating mechanism 410 to move to the hot-pressing station, so that the heating mechanism 410 is facing the material platform 310; then, the hot-pressing driving component 420 drives the heating mechanism 410 to move toward the material receiving platform 310 to heat the material. pressure.

Wherein, the heating mechanism 410 is arranged at the output end of the hot pressing drive assembly 420, and the hot pressing driving assembly 420 is arranged at the output end of the hot pressing moving mechanism; The moving mechanism is arranged at the output end of the hot-pressing drive assembly 420 ; both can realize the relative movement of the heating mechanism 410 .

Specifically, the hot-pressing driving assembly 420 and the hot-pressing moving mechanism may adopt a driving mechanism such as an electric cylinder, a linear module, or the like.

It should be explained that the hot pressing station may be another station different from the insulating film feeding station and the bus bar feeding station. For example, the hot pressing station can be set between the insulating film feeding station and the bus bar feeding station, and the splicing drive assembly 320 can drive the splicing platform 310 to the insulating film feeding station and the bus bar feeding station In this way, the hot pressing station is on the movement path of the material receiving platform 310. After the material receiving platform 310 receives the insulating film 1 and the bus bar 2, the material receiving driving component 320 can drive the material receiving platform 310 to move. To the hot pressing station, facing the hot pressing device 400 . Of course, the hot-pressing station can also be set at the insulating film feeding station or the bus bar feeding station on the side away from the other side, as long as it is ensured that the feeding drive assembly 320 can drive the feeding platform 310 to move between the three stations, i.e. Can.

Alternatively, the hot pressing station may also be a station overlapping with the insulating film feeding station or the bus bar feeding station. For example, the material receiving platform 310 first moves to the insulating film feeding station to receive the insulating film 1, and then moves to the bus bar feeding station to receive the bus bar 2; when the material is ready, the material receiving platform 310 stays at the bus bar feeding station Without moving, the heating mechanism 410 is driven by the hot-pressing moving mechanism to move to the bus bar loading station (that is, the hot-pressing station in the current embodiment), and then the heating mechanism 410 is driven toward the receiving platform 310 by the hot-pressing driving component 420 Exercise, achieve hot pressing.

In other embodiments, the insulating film feeding device 100 may be a device for preparing the finished insulating film 1 . It is easy to understand that for the initial material of the insulating film, its specifications may not meet the actual use needs; and the actual use needs should be designed according to the process requirements. To this end, the insulating film feeding device 100 is provided as a preparation device, which can prepare the insulating film 1 according to actual needs, thereby improving the applicability of the entire bus bar heat-pressing integrated machine.

For example, referring to FIG. 4 , the insulating film feeding device 100 may include: an insulating film unwinding mechanism 110 for releasing the insulating film tape; an insulating film slitting mechanism 120 , which is located downstream of the insulating film unwinding mechanism 110 and can The film tape is cut into a plurality of insulating films 1; the insulating film cutting mechanism 130, which is located downstream of the insulating film cutting mechanism 120, can cut the insulating film 1; the insulating film pulling mechanism 140 can extract the insulating film 1 and pull the insulating film 1 moves downstream in the first direction; the insulating film 1 is pulled by the insulating film pulling mechanism 140 and passes through the insulating film cutting mechanism 130 . After passing through the predetermined length, the insulating film cutting mechanism 130 cuts the insulating film 1 .

In this embodiment, the insulating film tape is not the finished insulating film 1 and cannot be used directly. The insulating film feeding device 100 needs to prepare the insulating film tape that does not meet the specification into the insulating film 1 that meets the specification.

It should be explained that the first direction can be regarded as the direction of the material's tape running; however, when the material is transported in the insulating film feeding device 100, in order to ensure the stability of the tape, its direction may be changed. The first direction is mainly used to describe the direction in which the material is pulled downstream by the insulating film pulling mechanism 140 , for example, the left-right direction shown in FIG. 4 .

Specifically, the insulating film tape is an initial material whose width and length do not meet the specifications; the insulating film slitting mechanism 120 can cut the insulating film tape into a plurality of materials that meet the specifications along the width direction; further, Through the insulating film cutting mechanism 130, the material can be cut to a length that meets the specifications.

The insulating film unwinding mechanism 110 is used to release the insulating film tape. In a specific embodiment, referring to FIG. 4 or FIG. 5 , the insulating film unwinding mechanism 110 includes an unwinding shaft, and the material roll formed by the insulating film material tape is sleeved on the unwinding shaft, and the unwinding shaft is driven by a servo motor, which can be actively rotated and released. Insulating film tape. A plurality of over-rollers are also arranged downstream of the unwinding shaft, which can tension the insulating film material tape and guide the insulating film material tape to move to the downstream mechanisms.

In order to cut the insulating film tape with a wider width into multiple tapes with a narrow width, it is necessary to cut the insulating film tape along the width direction thereof. In one embodiment, the insulating film slitting mechanism 120 includes a slitting assembly; the slitting assembly includes: an upper knife assembly 121 and a lower knife assembly 122 arranged side by side; the upper knife assembly 121 includes an upper knife shaft and is spaced on the upper knife shaft The lower cutter assembly 122 includes a lower cutter shaft and a plurality of lower cutters arranged on the lower cutter shaft at intervals; the upper cutter and the lower cutter correspond one by one; the slitting drive assembly 123 is connected to the upper cutter shaft and the lower cutter The cutter shaft can drive the upper cutter shaft and the lower cutter shaft to rotate, so as to make the upper cutter and the lower cutter rotate synchronously to realize slitting; the insulating film tape passes between the upper cutter assembly 121 and the lower cutter assembly 122, and the upper cutter The cutter and the lower cutter cooperate to cut the insulating film tape into a plurality of narrow tapes.

Referring to FIGS. 4 and 6 , in the illustrated embodiment, the upper knife assembly 121 includes two upper knives, and the lower knife assembly 122 includes two lower knives. It will be divided into three narrow strips.

It should be noted that on the upper cutter shaft, multiple upper cutters are arranged at intervals along the width direction of the insulating film tape; similarly, on the lower cutter shaft, multiple lower cutters are also arranged at intervals along the width direction of the insulating film tape. At the same time, the distance between two adjacent cutting knives is equivalent to the width of the required narrow strip.

Among them, the upper cutter and the lower cutter can be circular cutters, which are sleeved on the corresponding cutter shafts; the cutter shafts are rotated around their central axis under the drive of the slitting drive assembly 123, so that the circular cutters on them rotate along with them to achieve continuous , Stable cutting.

Wherein, the slitting drive assembly 123 may use a servo motor. In one embodiment, the slitting drive assembly 123 may include two sets of servo motors, which are respectively connected to the upper knife shaft and the lower knife shaft, so as to independently drive the upper knife shaft or the lower knife shaft to rotate. In yet another embodiment, the slitting drive assembly 123 may only include a set of servo motors connected to one of the knife shafts; at the same time, the upper knife shaft and the lower knife shaft are connected through a linkage mechanism 126; in this way, the slitting drive assembly 123 drives the When the corresponding cutter shaft rotates, the other cutter shaft can be driven to rotate accordingly through the linkage mechanism 126 . The linkage mechanism 126 may adopt a synchronous pulley assembly, a gear assembly and other structures that can cooperate to achieve linkage, which is not specifically limited in this application.

Of course, in other embodiments, the insulating film slitting mechanism 120 may also be composed of a plurality of independent cutting parts, and these cutting parts are arranged at intervals along the width direction of the insulating film tape, so as to cut corresponding parts of the insulating film tape respectively. ; detailed here.

Further, in order to ensure the slitting effect of the insulating film tape, the insulating film slitting mechanism 120 further includes: a front pressing component 124, located upstream of the slitting component; a rear pressing component 125, located downstream of the slitting component; the insulating film material After the tape passes through the front pressing component 124, it enters the slitting component; the slitted insulating film 1 further passes through the rear pressing component 125; the front pressing component 124 and the rear pressing component 125 can tension the materials in the slitting component.

Through the front pressing component 124 and the rear pressing component 125, both ends of the material entering the slitting component can be tensioned, so that the material is in a flat state, so that the slitting component can cut the material accurately.

Furthermore, since the material will be pulled and moved forward by the insulating film pulling mechanism 140, the front pressing component 124 and the rear pressing component 125 can use pressure rollers. When the tape is attached to the roller, the roller can rotate to match the traveling of the material, thereby preventing the front pressing component 124 and the rear pressing component 125 from contacting the surface of the material, interfering with the traveling of the material or abrading the surface of the material.

Of course, the front pressure component 124 and the rear pressure component 125 may also adopt other structures capable of supporting materials, as long as the materials can be flattened and tensioned on the front pressure component 124 and the rear pressure component 125 , which is not specifically limited in this application.

In one embodiment, both the front pressing assembly 124 and the rear pressing assembly 125 may include only one pressing roller. The material first enters the pressing roller of the front pressing assembly 124 and has a certain wrap angle on the pressing roller to facilitate the front pressing assembly 124 Then, the material enters the slitting component and is cut into multiple pieces of narrow width materials; the multiple narrow materials pass through the rear pressing component 125 and move towards the insulating film cutting mechanism 130; in the rear pressing component 125 The material also has a certain wrapping angle on the pressing roller of the rear pressure unit 125 so that the pressing roller of the rear pressing component 125 can tension the material. Referring to FIG. 5 , in the illustrated embodiment, the surface of the front pressing component 124 and the rear pressing component 125 for receiving the material is lower than the end surface of the slitting component to cut the material; the material enters the front pressing component 124 from top to bottom; , into the slitting component; then from top to bottom, into the rear pressing component 125; after passing through the rear pressing component 125, the material moves from bottom to top... In this way, the material can be pressed by the front pressing component 124 and the rear pressing component 125. tight.

In order to better tension the material, the front pressing component 124 and/or the rear pressing component 125 includes: a first pressing roller 1241 and a second pressing roller 1242 which are oppositely arranged, and the insulating film tape or insulating film 1 is pressed from the first pressing roller 1241 and the second pressing roller 1242. Pass between the pressing roller 1241 and the second pressing roller 1242; the pressing driving member 1243 can drive the relative movement of the first pressing roller 1241 and the second pressing roller 1242 to compress the insulating film tape between them or insulating film 1.

By pressing the driving member 1243, the first pressing roller 1241 and the second pressing roller 1242 can move relative to each other so as to approach or move away from each other. In this way, when the first pressing roller 1241 and the second pressing roller 1242 are far away from each other, the material can be easily passed through the belt, so that the material can be manually pulled out of the front pressing component 124 or the rear pressing component 125 during the first operation or roll change. When the equipment is running, the pressing driving member 1243 drives the first pressing roller 1241 and the second pressing roller 1242 to approach each other until the pressed material is between them. On the one hand, the two pressing rollers can press the material to better tension. The material, on the other hand, because the material can be pressed by the two pressure rollers, the material does not need to wrap around the pressure roller to ensure the tensioning effect. 4 , the material enters the front pressing component 124 horizontally and leaves the rear pressing component 125 horizontally. The pressure between the first pressing roller 1241 and the second pressing roller 1242 ensures that the state of the material is stable.

Wherein, the pressing driving member 1243 may adopt a driving mechanism such as an air cylinder and an electric cylinder. In one embodiment, one of the pressing rollers can be fixedly arranged, and the other pressing roller is connected to the pressing driving member 1243 , and can press against the fixed pressing roller under the driving of the pressing driving member 1243 . In another embodiment, the pressing driving member 1243 can simultaneously drive the two pressing rollers to move relative to each other. For example, the pressing driving member 1243 can include two air cylinders, which are respectively connected to one pressing roller and can drive the corresponding pressing roller toward the other. Roller movement.

Further, the front pressing assembly 124 and/or the rear pressing assembly 125 further includes a roller rotation driving member (not shown), which is connected to the first pressing roller 1241 and/or the second pressing roller 1242 and can drive the corresponding pressing roller Active rotation, which in turn facilitates material transport. Among them, the roller rotation driving part can use a driving component such as a motor. By driving the pressure roller to rotate, the material wound on the pressure roller is transported forward, thereby avoiding the friction of the material on the surface of the pressure roller. It is easy to imagine that the roller rotation driving member may only be connected to one of the pressing rollers. Since the two pressing rollers abut against each other during use, the actively rotating pressing roller will drive the other pressing roller to follow. Similarly, the roller rotation driving member can also drive the two pressing rollers to rotate synchronously at the same time.

In order to obtain the insulating film 1 of the required length, the insulating film cutting mechanism 130 includes: a first cutter 131 and a first cutter driver 132; the first cutter driver 132 is connected to the first cutter 131 and can drive the first cutter 131. The cutter 131 moves toward the insulating film 1 .

In one embodiment, the first cutting knife 131 is a long knife, and the long knife has a certain length along the width direction of the insulating film tape, and can cut all the slit narrow tapes at the same time. In other embodiments, the first cutting knife 131 may include a plurality of narrow cutting knives, which can cut each narrow material strip respectively. There is no specific limitation in this application.

The first cutter driving member 132 may adopt a driving mechanism such as an air cylinder, an electric cylinder, or the like. The plurality of slitted narrow material strips pass through the edge end of the first cutting knife 131, and after the required length has passed, the first cutting knife driving member 132 drives the first cutting knife 131 to approach to cut the narrow material belt.

Further, the insulating film cutting mechanism 130 further includes a first cutting knife avoiding driving member 133, which is connected to the first cutting knife 131 and can drive the first cutting knife 131 to be close to or away from the cutting station; when cutting the insulating film 1, The first cutter 131 is in the cutting station, and the first cutter driver 132 drives the first cutter 131 to approach to cut the insulating film 1; when the cutting is finished, the first cutter driver 132 drives the first cutter 131 away from and Release the insulating film 1 ; then, the first cutter evacuating driving member 133 drives the first cutter 131 away from the cutting station to expose the free end of the insulating film 1 .

It should be explained that the cutting station is the station where the first cutter 131 cuts the material. When the insulating film pulling mechanism 140 pulls the material downstream, the first cutter 131 is in the cutting position, and the blade end faces the material. After the material is pulled out to a required length, the first cutter driving member 132 drives the first cutter 131 to approach to cut the material. Then, the insulating film pulling mechanism 140 can continue to pull the material downstream to pull the material to a desired position (ie, the insulating film feeding station). At the same time, the first cutter avoidance driving member 133 can drive the first cutter 131 away from the cutting station, thereby exposing the free end of the material, so that the insulating film pulling mechanism 140 can extract the free end, thereby pulling the material to move downstream , in order to start a new round of material preparation. After the insulating film pulling mechanism 140 extracts the free end of the material, the first cutter avoidance driving member 133 can drive the first cutter 131 to approach the cutting station, so as to facilitate a new round of cutting.

Wherein, the first cutter avoidance driving member 133 may adopt a driving mechanism such as an air cylinder and an electric cylinder. The first cutter 131 may be provided at the output end of the first cutter avoidance driving member 133 , and the first cutter 131 may be provided at the output end of the first cutter driving member 132 . Alternatively, the first cutter 131 may be provided at the output end of the first cutter drive member 132 , and the first cutter drive member 132 may be provided at the output end of the first cutter avoidance drive member 133 .

In use, the first cutter avoidance driving member 133 can drive the first cutter 131 to move in any direction, as long as it can avoid the cutting station and expose the free end of the insulating film 1 . In order to prevent the movement of the first cutter 131 from interfering with the material transport, in one embodiment, the first cutter avoidance driving member 133 can drive the first cutter 131 to move along the extending direction of the material and away from the insulating film pulling mechanism 140; for example, 4, in the illustrated embodiment, the insulating film pulling mechanism 140 pulls the material from left to right. After the cutting is completed, the first cutting knife avoidance driving member 133 drives the first cutting knife 131 to move from right to left to move. The free end of the insulating film 1 is exposed.

Further, the insulating film cutting mechanism 130 further includes a cutter guide assembly located upstream of the first cutter 131; the cutter guide assembly includes: a guide plate 134 for receiving the cut insulating film 1; a plurality of guide bodies 135, which are arranged on the guide plate 134 at intervals along the width direction of the insulating film tape; any insulating film 1 passes between the two guide bodies 135, and the two guide bodies 135 can define the position of the insulating film 1 passing through.

It is easy to understand that after the insulating film tape is cut, the plurality of narrow tapes are independent of each other. Due to the change in tension on the tapes, these narrow tapes are easily displaced; if there is a displaced narrow tape, the final insulating film cutting mechanism 130 When cutting the insulating film 1, the cut insulating film 1 may have an incorrect version, and waste is likely to occur. To this end, a cutter guide assembly is provided, and the guide body 135 is used to define and guide each narrow material tape to travel correctly, so as to ensure the cutting effect of the insulating film 1 .

Referring to FIG. 3 , FIG. 7 and FIG. 8 , the guide plate 134 may be a horizontally disposed receiving plate, and the guide body 135 may be a convex block disposed on the guide plate 134 . When the insulating film tape is divided into three, four guide bodies 135 are arranged on the guide plate 134 along the width direction of the insulating film tape at intervals, and a channel is formed between two adjacent guide bodies 135 . At the same time, the guide body 135 extends along the running direction of the material and has a certain length. A narrow material belt passes through a channel, and the two opposite guides 135 will "clamp" the narrow material belt, thereby limiting the position of the narrow material belt; at the same time, the channel will guide the material belt to only go along The belt moves in the direction, thereby defining the position state of each narrow material belt.

In order to pull the material downstream, the insulating film pulling mechanism 140 includes: a pulling member 141 and a pulling driving assembly 142; the pulling driving assembly 142 is connected to the pulling member 141 and can drive the pulling member 141 to move downstream in the first direction.

Wherein, the pulling member 141 may adopt an extraction mechanism such as a clamp, a suction cup, etc., as long as the free end of the material can be extracted. The traction drive assembly 142 may adopt a drive mechanism such as an electric cylinder, a linear module, and the like. 3 and 9 , the main body of the traction drive assembly 142 extends along the first direction, that is, the left and right directions shown in the figure. After the traction member 141 extracts the free end of the material, the traction drive assembly 142 can drive the traction member 141 to move from left to right , Gradually pull out the material of the required length.

Further, the insulating film pulling mechanism 140 further includes: a first auxiliary assembly 143, the first auxiliary assembly 143 is arranged downstream of the insulating film cutting mechanism 130; the first auxiliary assembly 143 includes: a first supporting plate 1431 for supporting the cutting The insulating film 1 is formed; the first pressing block 1432 and the first auxiliary driving member 1433, the first auxiliary driving member 1433 is connected to the first pressing block 1432, and can drive the first pressing block 1432 to be close to or away from the first support plate 1431; The traction drive assembly 142 drives the traction member 141 to pull the insulating film 1 through the first auxiliary assembly 143 ; after pulling out the insulating film 1 of a predetermined length, the first auxiliary driving member 1433 drives the first pressing block 1432 to approach to press the first the support plate 1431, and then press the insulating film 1 on the first support plate 1431.

In the actual use process, the length of the finished insulating film 1 may be very long; in this case, after the insulating film 1 is cut, the fractured end will naturally hang down due to the loss of tension, which may cause the material to wrinkle or be folded. This will affect the later handling or use of the material. Therefore, by providing the first auxiliary component 143, the fractured end of the insulating film 1 can be clamped; at the same time, since the pulling member 141 extracts the other end of the insulating film 1, it can be seen that both ends of the finished insulating film 1 are controlled. Subsequently, the traction drive assembly 142 continues to drive the traction member 141 to move downstream, and the insulating film 1 can be tensioned, so that the insulating film 1 is stretched and stretched between the traction member 141 and the first auxiliary assembly 143 .

It should be added that, in order to avoid the displacement of the fracture end after the insulating film 1 is cut, it is preferable to make the first pressing block 1432 press the insulating film 1 on the first pallet 1431 before the insulating film cutting mechanism 130 cuts the insulating film 1 . . Specifically, after pulling out the insulating film 1 of the required length, the pulling member 141 no longer moves, and the first auxiliary driving member 1433 drives the first pressing block 1432 to approach the first supporting plate 1431 ; after pressing the insulating film 1 , the insulating film cutting mechanism 130 cuts the insulating film 1...

In order to transport the cut off finished insulating film 1 to the insulating film loading station so as to be received by the receiving platform 310 . In one embodiment, after the traction drive assembly 142 drives the traction member 141 to pull out the material of the required length, the material is in the insulating film feeding station; at this time, the insulating film cutting mechanism 130 cuts the insulating film 1, the insulating film 1 can fall on the material receiving platform 310 and be transported away by the material receiving platform. For example, in the insulating film loading station, the material receiving platform 310 is located under the pulling member 141 ; in this way, the pulling member 141 can directly pull out the material on the material receiving platform 310 under the driving of the traction drive assembly 142 .

In another embodiment, the insulating film feeding station may be located downstream of the insulating film cutting mechanism 130 and far away from the insulating film cutting mechanism 130 to prevent the mechanical structure from affecting the material receiving platform 310 to receive materials accurately. At this time, after the insulating film cutting mechanism 130 cuts the insulating film 1 , the traction drive assembly 142 will continue to drive the traction member 141 to move downstream, so as to completely guide the material to the insulating film loading station and place it on the material receiving platform 310 .

In this embodiment, a first auxiliary component 143 may also be provided; specifically, the first auxiliary driving member 1433 drives the first pressing block 1432 to approach to press against the first supporting plate 1431, thereby pressing the fracture end of the material; the insulating film is cut After the mechanism 130 cuts the insulating film 1, the traction drive assembly 142 will continue to drive the traction member 141 to move downstream to tension the material; then, in order to accurately transport the tensioned material to the insulating film feeding station, the first pressing block 1432 And the first pallet 1431 needs to clamp the material and move downstream with the traction member 141 . To this end, referring to FIG. 9 , the insulating film pulling mechanism 140 further includes a first auxiliary drive assembly 144; the first auxiliary drive assembly 144 is connected to the first auxiliary assembly 143 and can drive the first auxiliary assembly 143 to move in the first direction.

In actual use, after the traction member 141 and the first auxiliary component 143 control one end of the insulating film 1 respectively, the traction driving component 142 can drive the traction component 141 to move downstream, and the first auxiliary driving component 144 can drive the first auxiliary component 143 move upstream to tension the insulating film 1, and then the first auxiliary drive assembly 144 reversely drives the first auxiliary assembly 143 to move downstream with the traction member 141; alternatively, the traction drive assembly 142 can drive the traction member 141 downstream After the insulating film 1 is tensioned, the first auxiliary driving component 144 also drives the first auxiliary component 143 to move downstream; thus, the pulling member 141 cooperates with the first auxiliary component 143 to transport the insulating film 1 to the insulating film loader position so that the bonding platform 310 can receive the insulating film 1 .

Wherein, the first auxiliary drive assembly 144 may adopt a drive member such as an electric cylinder, a linear module or the like.

In addition, the insulating film feeding device 100 further includes a guiding mechanism 150; the guiding mechanism 150 is arranged downstream of the insulating film slitting mechanism 120 and upstream of the insulating film cutting mechanism 130; the guiding mechanism 150 includes: a guiding platform 151 for receiving and cutting The insulating film 1; a plurality of guide blocks 152 are arranged on the guide platform 151 at intervals along the width direction of the insulating film tape; any insulating film 1 passes between the two guide blocks 152, and the two guide blocks 152 can define The position of the insulating film 1 .

The structure of the guide mechanism 150 is similar to the cutter guide assembly. The guide blocks 152 arranged at intervals form a channel to limit the position and position of the material, so as to facilitate the accurate transport of the material and improve the accuracy of the material preparation.

4 and 10, a structure of a guiding mechanism 150 is shown in the figures, wherein the guiding block 152 is a cylindrical block, and there are a plurality of guiding blocks 152 along the width direction of the insulating film tape; for example, the insulating film tape When one is divided into three, there are four guide blocks 152 along the width direction of the insulating film tape. Further, in order to better define the position state of the material, multiple rows of guide blocks 152 may be provided along the direction of the material to travel, so as to guide the material to travel forward along the defined position.

For the bus bar feeding device 200, similar to the insulating film feeding device 100, a handling device can be used to directly transport the finished bus bar 2 to the bus bar feeding station. Alternatively, the bus bar feeding device 200 may adopt a bus bar preparation device, and through the bus bar preparation device, a bus bar material strip that does not meet the specifications can be prepared into a bus bar that meets the specifications.

11 , the busbar preparation device includes: a busbar unwinding mechanism 210 for releasing the busbar 2 ; a busbar cutting mechanism 220 , located downstream of the busbar unwinding mechanism 210 , capable of cutting the busbar 2 ; a busbar pulling mechanism 230, can extract the bus bar 2, and pull the bus bar 2 to move downstream along the first direction; the bus bar 2 is pulled by the bus bar pulling mechanism 230, passes through the bus bar cutting mechanism 220, and after passing through the predetermined length, the bus bar is cut The mechanism 220 cuts the bus bar 2 .

The busbar unwinding mechanism 210 is similar to the insulating film unwinding mechanism 110, and also includes an unwinding shaft on which the material roll formed of the busbar material tape is sleeved; the unwinding shaft is driven by a servo motor, which can actively rotate and release the busbar material bring. There are also a plurality of over-rollers downstream of the unwinding shaft, which can tension the bus bar material and guide the bus bar material to move to the downstream mechanisms.

The bus bar cutting mechanism 220 is similar to the insulating film cutting mechanism 130, and includes: a second cutter 221 and a second cutter driver 222; the second cutter driver 222 is connected to the second cutter 221 and can drive the second cutter 221 moves towards the bus bar 2 . The blade end of the second cutter 221 is facing the material. After the material is pulled out to a required length, the second cutter driver 222 can drive the second cutter 221 to approach the material to cut the material.

Further, the bus bar cutting mechanism 220 further includes a second cutter avoidance driving member 223, which is connected to the second cutter 221 and can drive the second cutter 221 to be close to or away from the cutting station; when cutting the bus bar 2, The second cutter 221 is at the cutting station, and the second cutter driver 222 drives the second cutter 221 to approach the bus bar 2; when the cutting is finished, the second cutter driver 222 drives the second cutter 221 to move away from and cut off the bus bar 2. Release the bus bar 2 ; then, the second cutter avoidance driving member 223 drives the second cutter 221 away from the cutting station to expose the free end of the bus bar 2 .

It should be explained that the cutting station for the bus bar cutting mechanism 220 is the cutting station for the bus bar 2, and the cutting station for the insulating film cutting mechanism 130 above is the cutting station for the insulating film 1, The positions of the two stations do not overlap, but for the convenience of description, they are both called cutting stations. When the cutting station is mentioned in the text, it will be clear whether it is for the bus bar 2 or the insulating film 1 .

Similarly, the second cutter avoidance driving member 223 is similar to the first cutter avoidance driving member 133 , which will not be repeated here.

Further, the bus bar cutting mechanism 220 further includes a limit component, which is arranged upstream of the second cutter 221; the limit component includes two limit bars 224 spaced along the width direction of the bus bar 2; the bus bar 2 is separated from the two limit bars. Passing between the position rods 224, the two position limit rods 224 can define the position of the passing bus bar 2.

It is easy to understand that the two limiting rods 224 form a channel for the bus bar 2 to pass through; at this time, the two limiting rods 224 can "clamp" the bus bar 2 , thereby limiting the position of the bus bar 2 .

Furthermore, in order to conveniently adjust the position of the limit rod 224 so as to adjust the tape running position of the bus bar 2, the limit assembly further includes: a guide rod 225 extending along the width direction of the bus bar 2, and the two limit rods 224 slide. It is arranged on the guide rod 225; the adjusting member 226 connects the two limit rods 224 and enables the two limit rods 224 to move along the guide rod 225; wherein, the end of the guide rod 225 away from the adjusting member 226 is provided with a blocking plate 227 , an elastic member 228 is arranged between the blocking plate 227 and the two limiting rods 224 ; when the two limiting rods 224 move toward the blocking board 227 , the elastic member 228 is compressed.

Referring to FIG. 12 , the guide rod 225 can be arranged on the knife holder of the second cutter 221 ; at this time, the limit rod 224 is closer to the second cutter 221 , which can better control the position of the material, so as to facilitate the second cutter 221 Accurately cutting the material also facilitates the accurate pulling of the material by the bus bar pulling mechanism 230 . The two limit rods 224 can be independently sleeved on the guide rods 225; in order to avoid changes in the distance between the two limit rods 224 during adjustment, the two guide rods 225 can also be set on the same mounting block, and The mounting block is slidably arranged on the guide rod 225 . When the position of the limit rod 224 needs to be adjusted, the limit rod 224 is driven by the adjusting member 226 to move along the guide rod 225. If the limit rod 224 moves in the direction of the elastic member 228, the elastic member 228 will be further compressed, and the reverse caused by the compression The acting force resists the limit rod 224, and cooperates with the force in the other direction of the adjusting member 226, so that the limit rod 224 stays at the desired position. If the limit rod 224 moves away from the direction of the elastic member 228, the elastic member 228 will rebound. As long as the elastic member 228 is always in a compressed state, its reverse force can match the force applied by the adjustment member 226 to the limit rod 224, so that The limit lever 224 stays at the desired position.

The adjusting member 226 may adopt a structure such as a micrometer, a manual adjustment rod, etc., as long as it can exert force on the limit rod 224 and adjust the position of the limit rod 224 , which is not limited in this application.

Furthermore, the bus bar pulling mechanism 230 further includes a second auxiliary drive assembly 234; the second auxiliary drive assembly 234 is connected to the second auxiliary assembly 233 and can drive the second auxiliary assembly 233 to move in the first direction.

The second auxiliary assembly 233 can cooperate with the pulling member 231 to tension the cut bus bar 2; further, through the second auxiliary driving assembly 234, it can cooperate with the pulling driving assembly 232, after the bus bar 2 is tensioned, the bus bar 2 is pulled The component 231 and the second auxiliary component 233 move the finished bus bar 2 to the bus bar loading station.

It can be understood that the second auxiliary assembly 233 is similar to the first auxiliary assembly 143, and the second auxiliary driving assembly 234 is similar to the first auxiliary driving assembly 144, and details are not repeated here.

Continuing to refer to FIG. 1 or FIG. 2 , in addition to being composed of a bus bar 2 and an insulating film 1 , the second type of bus bar 2 b also has a feature that one of the two ends of the bus bar 2 protruding from the insulating film 1 is raised upwards so that for connecting the junction box.

One side of the platform 310 is facing the protruding end of the bus bar 2; the bus bar bending mechanism 240 includes a bending part 241 and a bending driving part 242; the bending driving part 242 is connected to the bending part 241 and can drive the bending part 241 moves toward the protruding end of the bus bar 2 , and then folds the bus bar 2 .

For the bus bar bending mechanism 240, it can be arranged at one end of the bus bar feeding station, facing the end of the pulled out bus bar 2; at this time, after the bus bar 2 is placed in the material receiving platform 310, Its ends are folded by the bus bar folding mechanism 240 .

Alternatively, the bus bar bending mechanism 240 may be disposed at one end of the hot pressing station, facing the bus bar 2 protruding from the end of the material platform 310; The bending mechanism 240 folds the end of the bus bar 2 .

Alternatively, the bus bar bending mechanism 240 can be arranged at one end of the insulating film feeding station, facing the end of the pulled out bus bar 2; at this time, the material receiving platform 310 first accepts the bus bar 2, and then moves to the insulating film The loading station receives the insulating film 1 ; and the bus bar bending mechanism 240 folds the end of the bus bar 2 .

Alternatively, the bus bar bending mechanism 240 may be provided with another station, and after receiving the bus bar 2 , the material receiving platform 310 moves to this station, so that the bus bar bending mechanism 240 is facing the bus bar protruding from the end of the material platform 310 . 2, and then realize the folding of the end of the bus bar 2.

In one embodiment, the material receiving platform 310 first receives the insulating film 1 and then receives the bus bar 2, so that the bus bar 2 is placed on the insulating film 1; when the material receiving platform 310 reaches the bending station, the bus bar bending mechanism 240 is integrally The bus bar 2 protruding from the end of the material receiving platform 310 is not higher than the bus bar 2; the bus bar 2 is in place, the bending driver 242 drives the bending member 241 to move from bottom to top, and the bus bar 2 protrudes from the end outside the material receiving platform 310 Fold it upwards so that the end of the bus bar 2 is lifted upwards.

Of course, when the overlapping mode of the bus bar 2 and the insulating film 1 is changed, the initial position of the bus bar bending mechanism 240 will be adjusted accordingly, as long as the end of the bus bar 2 is lifted away from the insulating film 1 .

Further, in order to ensure the folding effect, in one embodiment, the bus bar bending mechanism 240 further includes a pressing component (not shown); before the bending member 241 folds the end of the bus bar 2, the pressing component Press the position where the bus bar 2 is to be folded, and press the bus bar 2 on the material receiving platform 310; in this way, when the bending driving member 242 drives the bending member 241 to move toward the bus bar 2, the bending member 241 can stick to The pressing component moves, and then presses the folded portion on the pressing component, so as to press out the crease and ensure the stability of the end of the bus bar 2 being lifted.

In other embodiments, the bus bar bending mechanism 240 may be disposed at one end of the hot pressing station and facing the bus bar 2 protruding from the end of the material platform 310 ; at this time, the hot pressing device 400 needs to press the bus bar 2 and the insulating film 1 In this way, the hot pressing device 400 can be used as the "pressing component" in the above-mentioned embodiment; that is, the bus bar 2 is pressed on the material receiving platform 310 by the hot pressing device 400, so as to facilitate the folding of the bus bar. The bending mechanism 240 folds the bus bar 2 .

It should also be added that when the insulating film feeding device 100 includes the insulating film slitting mechanism 120, the insulating film feeding device 100 can prepare multiple insulating films 1 at a time. Therefore, the bus bar feeding device 200 may include multiple sets of bus bars. The strip preparation device is used to prepare a plurality of bus bars 2 at one time, thereby accelerating the efficiency of preparing the second type of bus bars 2b by the integrated bus bar heat pressing machine.

Of course, when actually designing the structure, each group of busbar preparation devices may include an independent busbar unwinding mechanism 210 , busbar cutting mechanism 220 , busbar pulling mechanism 230 and busbar bending mechanism 240 .

Alternatively, in order to simplify the structure, the bus bar cutting mechanism 220 may only include a set of second cutters 221 and a second cutter driver 222; at this time, the multiple bus bars unwinding from the multiple sets of bus bar unwinding mechanisms 210 are along the bus bars. Arranged side by side in the width direction, the second cutter 221 has a certain length along the width direction of the bus bar, and can cut all the bus bar material strips at the same time.

In addition, when the insulating film feeding device 100 includes the insulating film slitting mechanism 120, since the final finished insulating film 1 is cut from insulating film tapes, in order to avoid the narrow tapes after slitting not being cut due to the influence of the distance too far The insulating film tape is cut, so that the insulating film tape is torn or displaced. The adjacent relationship of the narrow tape is actually very close to the overall state of the insulating film tape, that is, the distance between the two adjacent narrow tapes. very small. However, for multiple sets of bus bar feeding devices 200 , due to the occupation and arrangement of the equipment, the distance between two adjacent bus bars 2 to be finally prepared is relatively large. In order to facilitate access to a plurality of insulating films 1 and a plurality of bus bars 2 with different pitches, the material receiving platform 310 includes: a plurality of material receiving tables 311, any of which extends along the first direction and has a certain length; The driving component 312 can drive a plurality of receiving tables 311 to move relative to each other, so as to adjust the distance between two adjacent receiving tables 311; When receiving the insulating film 1, the first distance is between the two adjacent receiving tables 311; when the receiving platform 310 moves to the bus bar feeding device 200 to receive the bus bar 2, the distance between the two adjacent receiving tables 311 spaced apart by a second distance; the second distance is greater than the first distance.

In one embodiment, the variable-pitch driving assembly 312 may include a plurality of variable-pitch driving members 3121 , and the variable-pitch driving members 3121 are connected to the receiving table 311 in a one-to-one correspondence. Referring to FIG. 13 , when the distance needs to be changed, the variable-distance driving member 3121 drives the corresponding material receiving table 311 to approach or move away from the adjacent material receiving table 311 . Among them, the variable-pitch driving member may adopt a driving member such as an electric cylinder, a linear module, and the like.

In another embodiment, the variable-pitch drive assembly 312 may include only one variable-pitch drive member 3121 ; for example, referring to FIG. 14 , a connecting member 3122 is provided between two adjacent receiving tables 311 , and the receiving tables 311 can be along the corresponding The connecting member 3122 moves; the variable-pitch driving member 3121 is connected to a material receiving table 311 on the most side. In this way, when it is necessary to adjust to the second distance, the variable-pitch driving member 3121 drives the most lateral one of the receiving tables 311 to move outward, and when the receiving table 311 moves to the end of the connecting member 3122, it will drive an adjacent one of the receiving tables 311 moves outward; when the adjacent material receiving table 311 moves to the end of the corresponding connecting piece 3122, it will drive the next adjacent material receiving table 311 to move outward... When it needs to be adjusted to the first distance, the variable-pitch driver 3121 drives The most lateral one of the receiving tables 311 moves to the adjacent receiving table 311 until the connecting piece 3122 is connected to one end of the adjacent receiving table 311, or when the two receiving tables 311 are in contact, the two receiving tables 311 It can move to the next adjacent material receiving table 311...wherein, the connecting member 3122 can adopt a connecting mechanism such as a connecting rod and a cam structure.

For another example, referring to FIG. 15 , the variable-pitch drive assembly 312 may include only one variable-pitch drive member 3121 , and the variable-pitch drive member 3121 can drive all the receiving tables 311 to perform position changes; at this time, the variable-pitch drive assembly 312 also It includes a plurality of guide members 3123, and each guide member 3123 is radially arranged; in this way, when the second distance needs to be adjusted, the variable-distance driving member 3121 drives the receiving table 311 to move along the guide member 3123 toward the radial direction, so that each receiving table 311 Away from each other; when it needs to be adjusted to the first distance, the variable-pitch driving member 3121 drives the receiving table 311 to move along the guide member 3123 toward the shrinking direction, so that the receiving tables 311 are close to each other. Wherein, the guide member 3123 may adopt a guide member such as a guide rod, a guide rail, and a cam structure.

To sum up, the actual structure of the variable-pitch drive assembly 312 can be various, as long as the relative position of each receiving table 311 can be changed, which is not specifically limited in this application.

Further, the plurality of receiving tables 311 are arranged side by side along the second direction; the variable-pitch driving component 312 can drive the plurality of receiving tables 311 to move relatively along the second direction; the first direction and the second direction are perpendicular to each other and form a horizontal plane .

As can be seen from the above, the first direction is the direction in which the insulating film pulling mechanism 140 pulls the insulating film 1 and the bus bar pulling mechanism 230 pulls the bus bar 2 . By pulling out the insulating film 1 and the bus bar 2 along the first direction, the final obtained insulating film 1 and the bus bar 2 extend along the first direction, so that the receiving table 311 extending along the first direction can directly receive the insulating film 1 and the bus bar 2 . The bus bar 2, so that the two are superimposed together, which is convenient for subsequent hot pressing.

It should be added that, in other embodiments, the direction in which the insulating film pulling mechanism 140 pulls the insulating film 1 , the direction in which the bus bar pulling mechanism 230 pulls the bus bar 2 , and the extending direction of the material receiving table 311 may also be different. When feeding, adjust the direction of the finished insulating film 1 , the finished bus bar 2 or the material receiving table 311 correspondingly, so that the material receiving table 311 can receive the material.

Correspondingly, the second direction is a direction perpendicular to the first direction in the horizontal plane. Specifically, on the receiving stage 311, the first direction is the length direction of the insulating film 1 and the bus bar 2, and the second direction is the width direction of the insulating film 1 and the bus bar 2. At the same time, the second direction is also a plurality of The arrangement direction of the insulating film 1 or the plurality of bus bars 2 .

By arranging the plurality of receiving tables 311 along the second direction, it is convenient for each receiving table 311 to receive the corresponding insulating film 1 or the bus bar 2 .

Further, by driving the plurality of receiving tables 311 to move relatively along the second direction by the variable-distance driving component 312 , the distance between the receiving tables 311 can be quickly adjusted.

In addition, since the insulating film 1 and the bus bar 2 are sheet-like materials, they are easily separated from the receiving table 311. Therefore, an air hole 313 can be opened on the receiving table 311. The air is pumped, so that a negative pressure is formed inside the air hole 313 , and then the insulating film 1 on the receiving table 311 is sucked.

Referring to FIG. 13 , FIG. 14 or FIG. 15 , along the first direction (up and down direction shown in the figure), the receiving table 311 is provided with a plurality of air holes 313 arranged at intervals, so as to facilitate the finished insulating film 1 extending along the first direction and the busses The strip 2 can be sucked stably. If the finished insulating film 1 and the bus bar 2 have wider widths, a plurality of air holes 313 can be opened on the material receiving table 311 along the second direction (the left and right direction shown in the figure), so as to better absorb materials.

When multiple sets of insulating films 1 and bus bars 2 need to be hot-pressed, in one embodiment, the hot-pressing device 400 may include only one set of heating mechanisms 410 , which can sequentially hot-press each group of insulating films 1 under the driving of the hot-pressing driving assembly 420 and bus bar 2.

It should be added that when the hot pressing station is an independent station, the hot pressing driving assembly 420 may only include a driving assembly for driving the heating mechanism 410 to move in the vertical direction. Specifically, in the hot pressing station, the hot pressing device 400 is suspended above the material receiving platform 310; when hot pressing is required, the hot pressing driving component 420 drives the heating mechanism 410 to move from top to bottom, presses the material joining platform 310, and realizes heat pressure.

When the hot-pressing station overlaps with other stations, the devices corresponding to the other stations act, and the hot-pressing device 400 needs to be avoided. For this reason, the hot-pressing drive assembly 420 also includes another driver that drives the heating mechanism 410 away from the hot-pressing station. components. For example, referring to FIG. 16 , the hot-pressing driving assembly 420 includes a driving assembly 1 421 that drives the heating mechanism 410 to move in the vertical direction, and a driving assembly 2 422 that drives the heating mechanism 410 to move in the horizontal direction; when hot pressing is required, the driving assembly 2 422 firstly drives the heating mechanism 410 back to the hot pressing station; at this time, the hot pressing device 400 is suspended above the material receiving platform 310; then, the driving component 421 drives the heating mechanism 410 to press against the material receiving platform 310 to achieve hot pressing; After the hot pressing is completed, the second driving component 422 drives the heating mechanism 410 away from the hot pressing station, so as to facilitate the actions of other mechanisms.

In yet another embodiment, the hot pressing device 400 may include a plurality of groups of heating mechanisms 410 arranged side by side in the second direction; the heating mechanisms 410 are in one-to-one correspondence with the material receiving table 311, so as to perform the heating operation on a group of finished insulating films 1 and bus bars 2 respectively. heat press. It should be noted that, in this embodiment, the adjacent two groups of heating mechanisms 410 may be arranged at a first distance, may be arranged at a second distance, or may be arranged at other distances, as long as it is ensured that the receiving table 311 is loaded When the finished insulating film 1 and the bus bar 2 arrive at the hot pressing station, the variable-pitch driving member 3121 can drive the receiving table 311 to adjust so as to correspond to the heating mechanism 410 .

It should be explained that the main purpose of the insulating film 1 is to isolate the bus bar 2 and the battery slices 11 , and at the same time, it also needs to assist in realizing the connection between the bus bar 2 and the battery slice 11 to avoid the position shift of the bus bar 2 . Therefore, it is necessary to hot-press the bus bar 2 and the insulating film 1 together, and first ensure that the relative positions of the two are fixed; then, when connecting with the battery string 10, the insulating film 1 will be hot-pressed to the battery string 10 again. to further define the connection relationship.

Specifically, in order to avoid a short circuit between the bus bar 2 and the battery string 10, and at the same time to ensure that the position of the bus bar 2 and the battery string 10 is fixed, the insulating film 1 is made of a special material, such as EPCCE material; its characteristic is that during hot pressing, its material The hot-pressed surface in the battery will be hot-melted, which facilitates the bonding of the bus bar 2 and the insulating film 1; That is to say, after the bus bar 2 is transported to the battery string 10 , there will be a hot pressing device to further hot press the bus bar 2 and the insulating film 1 , so that the other hot pressing surface of the insulating film 1 is hot-melted and bonded to the battery string 10 . , thereby ensuring insulation and fixation between the bus bar 2 and the battery string 10 .

The heating mechanism 410 is mainly used to provide heat to achieve thermal fusion of the insulating film 1 . To this end, the thermal mechanism 410 includes a heating block 411 extending along the first direction; in this way, the heating block 411 can efficiently heat press the finished insulating film 1 and the bus bar 2 . The heating block 411 is mainly made of a material with good thermal conductivity, such as copper; a heating rod is arranged in the heating block 411; the heating rod can be activated to heat the heating block 411; The heat on the heating block 411 can be transferred to the material.

Further, in order to prevent the heating block 411 from directly contacting the material and causing the material to stick to the heating block 411, the heating mechanism 410 further includes a plurality of pressing pins 412, which are arranged on the heating block 411 at intervals along the first direction; The heating block 411 can move in the heating block 411; the end of the pressing needle 412 that penetrates the top surface of the heating block 411 has a stopper, which can prevent the pressing needle 412 from leaving the heating block 411; The head is used to abut the bus bar 2 and the insulating film 1; the pressing pin 412 is covered with an elastic member 413; one end of the elastic member 413 abuts the bottom surface of the heating block 411, and the other end abuts the pressing head; during hot pressing, the hot pressing drives the assembly 420 drives the heating mechanism 410 to approach the material receiving platform 310, and the pressing needle 412 first abuts the material receiving platform 310; as the hot pressing drive assembly 420 continuously drives the heating mechanism 410 to approach the material receiving platform 310, the pressing needle 412 gradually penetrates the top of the heating block 411. On the surface, the elastic member 413 is compressed.

Referring to FIGS. 16 and 17 , the joining platform 310 transports the finished insulating film 1 and the bus bars 2 to the hot pressing station, and the heating mechanism 410 is suspended above the joining platform 310 , facing the insulating film 1 and the bus bars 2 . Subsequently, the hot-pressing driving component 420 drives the heating mechanism 410 to move from top to bottom, and the pressing needle 412 first abuts against the material; the hot-pressing driving component 420 continues to drive the heating mechanism 410 to move downward; the heating block 411 keeps approaching the material, and the pressing needle 412 has One end of the indenter is always against the material, and the end of the indenter 412 with a stopper gradually penetrates the heating block 411; Therefore, the pressing needle 412 always presses the material.

By pressing the material by the pressing needle 412, the position of the material can be further limited, so as to ensure that the heating block 411 heats the material accurately.

It is easy to imagine that when the prepared finished insulating film 1 and bus bar 2 are long, only one heating block 411 is used for a set of heating mechanisms 410, and the heating block 411 needs to be set correspondingly very long. There may be a temperature difference at the location, which will affect the final hot pressing effect. To this end, referring to FIG. 16 , a group of heating mechanisms 410 may include a plurality of heating blocks 411, and the plurality of heating blocks 411 are arranged side by side along the first direction; at this time, each heating block 411 has an independent heating rod or other heating element in it Heating is performed to ensure the temperature of each heating block 411 .

The conveying device 500 includes: conveying the extractor 510 and the conveying drive mechanism 520, the conveying drive mechanism 520 is connected to the conveying extractor 510, and can drive the conveying extractor 510 to extract the hot-pressed bus bar 2 and the insulating film 1 from the receiving platform 310, And transfer the hot-pressed bus bar 2 and insulating film 1 to the outside.

It should be added that, in order to cooperate with the handling device 500 to unload materials, there may also be a blanking station on the movement path of the material receiving platform 310 . Specifically, after the hot pressing is completed, the insulating film 1 and the bus bar 2 are bonded together, and one end of the bus bar 2 is lifted to form the second bus bar 2b; The second type of bus bar 2b is transported to the unloading station, so that the conveying drive mechanism 520 drives the conveyance extractor 510 to receive the second type of bus bar 2b at the unloading station; after the second type of bus bar 2b is taken away, the material receiving drive The assembly 320 can drive the material receiving platform 310 to go to the insulating film feeding station or the bus bar feeding station to receive a new round of materials.

Of course, it is easy to imagine that the blanking station can also overlap with the hot-pressing station, that is, after the hot-pressing device 400 hot-presses the material in the hot-pressing station, the hot-pressing device 400 is transferred, and the receiving platform 310 does not Then, the conveying device 500 moves to the hot pressing station, and the second type of bus bar 2b on the conveying device 500 is extracted.

Wherein, the conveying extractor 510 may adopt extraction components such as suction cups, grippers, etc.; the conveying driving mechanism 520 may include two groups of driving components for driving the conveying extractor 510 to move in the vertical direction and in the horizontal direction (the driving components may use Electric cylinder or linear module and other driving components), the driving member that drives the transport extractor 510 in the vertical direction can receive the second type of bus bar 2b near the material receiving platform 310 when the transport extractor 510 reaches the unloading station, And the driving member for driving the conveying extractor 510 in the horizontal direction can drive the conveying extractor 510 to be close to or away from the unloading station.
