[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0037] First refer to Figure 1 and Figure 2 , Figure 1 A photovoltaic cell is shown, which is composed of a plurality of cell strings 10. Specifically, referring to Figure 2The battery string 10 is composed of a plurality of battery cells 11, and the plurality of battery cells 11 are connected by welding strips 12; the welding strips 12 protrude at both ends of the battery string 10; the welding strips 12 between the plurality of battery strings 10 are connected by the first bus bar 2a to realize busing; among the plurality of battery strings 10 connected by the same first bus bar 2a, there is also a second bus bar 2b between two adjacent 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.

[0038] It should be noted that the description is given with “a plurality of battery strings 10 connected to the same first type bus bar 2 a” as one battery string 10 . Figure 2 In a group of battery strings 10, since both ends of each battery string 10 have protruding welding strips 12, two first-type bus bars 2a need to be configured to connect the welding strips 12 protruding from the ends of the same side of each battery string 10. At the same time, since both first-type bus bars 2a need to be connected to the junction box, two second-type bus bars 2b can be configured between any two adjacent battery strings 10 in a group of battery strings 10 to connect one first-type bus bar 2a respectively.

[0039] Specific reference Figure 1 or Figure 2 The two second bus bars 2b between two adjacent battery strings 10 are connected to one of the first bus bars 2a at one end and extend toward the other first bus bar 2a at the other end; at the same time, the end extending toward the other first bus bar 2a is tilted upward to facilitate connection to the junction box.

[0040] Please refer to Figures 3 to 15 The present application discloses a busbar hot-pressing integrated machine, which is characterized in that it includes: an insulating film feeding device 100, used to supply an insulating film 1; a busbar feeding device 200, used to supply a busbar 2; a material receiving device 300, the material receiving device 300 includes a material receiving platform 310 and a material receiving drive component 320; the material receiving drive component 320 is connected to the material receiving platform 310, and can drive the material receiving platform 310 to move between the insulating film feeding device 100 and the busbar feeding device 200; a hot pressing device 400, the hot pressing device 400 includes a heating mechanism 410 and a hot pressing drive component 420; the hot pressing drive component 420 is connected to the heating mechanism 410, and can drive the heating mechanism 410 to move toward the material receiving platform 310.

[0041] Among them, the material receiving platform 310 can be driven by the material receiving driving component 320 to move to the insulating film loading device 100 to receive the insulating film 1, and then move to the bus bar loading device 200 to receive the bus bar 2; then, the hot pressing driving component 420 can drive the heating mechanism 410 to approach the material receiving platform 310 for hot pressing, so that the bus bar 2 and the insulating film 1 are bonded together.

[0042] In one embodiment, the insulating film loading device 100 may be a handling device, such as a robot or an overhead crane, which can directly carry the finished insulating film 1 to the receiving platform 310. Similarly, the busbar loading device 200 may also be a similar handling device. At this time, the finished insulating film 1 and the finished busbar 2 are materials that meet the specifications and can be directly hot-pressed. After being transported to the receiving platform 310, the hot-pressing device 400 can directly hot-press the two.

[0043] It should be added that when the insulating film loading device 100 and the bus bar loading device 200 are handling devices, the receiving device 300 may only include the receiving platform 310; that is, when loading materials, the receiving platform 310 may be fixed, and the insulating film loading device 100 and the bus bar loading device 200 sequentially carry the insulating film 1 and the bus bar 2 to the receiving platform 310. After the materials are in place, the hot pressing drive assembly 420 drives the heating mechanism 410 to move toward the receiving platform 310 to perform hot pressing on the materials.

[0044] Of course, the material receiving device 300 may also include a material receiving platform 310 and a material receiving drive assembly 320. In this case, the material receiving platform 310 has at least two working stations: an insulating film loading station and a busbar loading station. In one working cycle, the material receiving drive assembly 320 can drive the material receiving platform 310 to move to the insulating film loading station, waiting for the insulating film loading device 100 to move the finished insulating film 1 to the material receiving platform 310; the material receiving drive assembly 320 can also drive the material receiving platform 310 to move to the busbar loading station, waiting for the busbar loading device 200 to move the finished busbar 2 to the material receiving platform 310.

[0045] It should be explained that, during the loading process, the receiving platform 310 can first receive the insulating film 1 and then the busbar 2; or, the receiving platform 310 can first receive the busbar 2 and then the insulating film 1; because, whether the busbar 2 is placed on the insulating film 1 or the insulating film 1 is placed on the busbar 2, it does not affect the hot pressing of the two by the hot pressing device 400. As long as the busbar 2 can be bonded to the insulating film 1, the busbar hot pressing machine of the present application does not specifically limit the material stacking method, that is, the order of loading.

[0046] It is also necessary to explain that when the insulating film loading device 100 and / or the busbar loading device 200 is a handling device, the receiving device 300 may include a receiving platform 310 and a receiving drive assembly 320. At this time, the receiving drive assembly 320 may drive the receiving platform 310 to move to the insulating film loading station, so that the insulating film loading device 100 can carry the finished insulating film 1 to the receiving platform 310; the receiving drive assembly 320 may also drive the receiving platform 310 to move to the busbar loading station, so that the busbar loading device 200 can carry the finished busbar 2 to the receiving platform 310.

[0047] In addition, for the hot pressing device 400, its main body can be fixed. After the loading is completed, the material receiving platform 310 is driven by the material receiving drive component 320 to move to the corresponding station of the hot pressing device 400 - the hot pressing station, so that the hot pressing device 400 can realize hot pressing of the material.

[0048] Alternatively, the hot pressing device 400 further includes a hot pressing moving mechanism (not shown), which 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 assembly 320 drives the material receiving platform 310 to move to the hot pressing station (or, when the material receiving platform 310 does not move, the basic station where the material receiving platform 310 is fixed 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 directly connected to the material receiving platform 310; then, the hot pressing driving assembly 420 drives the heating mechanism 410 to move toward the material receiving platform 310 to perform hot pressing on the material.

[0049] Among them, the heating mechanism 410 is arranged at the output end of the hot pressing driving component 420, and the hot pressing driving component 420 is arranged at the output end of the hot pressing moving mechanism; or, the heating mechanism 410 is arranged at the output end of the hot pressing moving mechanism, and the hot pressing moving mechanism is arranged at the output end of the hot pressing driving component 420; both can realize the related movement of the heating mechanism 410.

[0050] Specifically, the hot pressing driving assembly 420 and the hot pressing moving mechanism can adopt driving mechanisms such as electric cylinders and linear modules.

[0051] It should be explained that the hot pressing station can be another station different from the insulating film loading station and the bus bar loading station. For example, the hot pressing station can be set between the insulating film loading station and the bus bar loading station, and the material receiving drive component 320 can drive the material receiving platform 310 to reciprocate between the insulating film loading station and the bus bar loading 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 drive component 320 can drive the material receiving platform 310 to move to the hot pressing station and face the hot pressing device 400. Of course, the hot pressing station can also be set on the side of the insulating film loading station or the bus bar loading station away from each other, as long as it is ensured that the material receiving drive component 320 can drive the material receiving platform 310 to move between the three stations.

[0052] Alternatively, the hot pressing station can also be a station that overlaps with the insulating film loading station or the busbar loading station. For example, the material receiving platform 310 first moves to the insulating film loading station to receive the insulating film 1, and then moves to the busbar loading station to receive the busbar 2; after the material is prepared, the material receiving platform 310 stays at the busbar loading station, and the hot pressing moving mechanism drives the heating mechanism 410 to move to the busbar loading station (that is, the hot pressing station in the current embodiment), and then the hot pressing driving component 420 drives the heating mechanism 410 to move toward the material receiving platform 310 to achieve hot pressing.

[0053] 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 the specifications of the initial material of the insulating film may not meet the actual use needs; and the actual use needs must be designed according to the process requirements. For this reason, the insulating film feeding device 100 is set as a preparation device, which can prepare the insulating film 1 according to actual needs, thereby improving the applicability of the entire busbar hot pressing machine.

[0054] For example, refer to Figure 4 The insulating film loading device 100 may include: an insulating film unwinding mechanism 110, for releasing the insulating film tape; an insulating film slitting mechanism 120, which is arranged downstream of the insulating film unwinding mechanism 110 and can slit the insulating film tape into multiple insulating films 1; an insulating film cutting mechanism 130, which is arranged downstream of the insulating film slitting mechanism 120 and can cut the insulating film 1; an insulating film traction mechanism 140, which can extract the insulating film 1 and traction the insulating film 1 to move downstream along a first direction; the insulating film 1 is pulled by the insulating film traction mechanism 140 and passes through the insulating film cutting mechanism 130, and after passing out a predetermined length, the insulating film cutting mechanism 130 cuts the insulating film 1.

[0055] In this embodiment, the insulating film strip is not a finished insulating film 1 and cannot be used directly. Instead, the insulating film strip that does not meet the specifications needs to be prepared into an insulating film 1 that meets the specifications by an insulating film loading device 100 .

[0056] It should be explained that the first direction can be regarded as the material running direction; however, when the material is running in the insulating film feeding device 100, in order to ensure the stability of the running, its direction may change. Therefore, the first direction is mainly used to describe the direction in which the insulating film traction mechanism 140 pulls the material to run downstream. For example, Figure 4 The left and right direction of the display.

[0057] Specifically, the insulating film strip is an initial material whose width and length do not meet the specifications; through the insulating film slitting mechanism 120, the insulating film strip can be cut into multiple materials that meet the specifications along the width direction; further, through the insulating film cutting mechanism 130, the material can be cut into a length that meets the specifications.

[0058] The insulating film unwinding mechanism 110 is used to release the insulating film strip. Figure 4 or Figure 5 The insulating film unwinding mechanism 110 includes an unwinding shaft, and the insulating film strip is sleeved on the unwinding shaft. The unwinding shaft is driven by a servo motor and can actively rotate and release the insulating film strip. A plurality of rollers are also provided downstream of the unwinding shaft to tighten the insulating film strip and guide the insulating film strip to move to the downstream mechanisms.

[0059] In order to cut a wide insulating film strip into multiple narrow strips, it is necessary to cut the insulating film strip along its width direction. In one embodiment, the insulating film cutting mechanism 120 includes a cutting assembly; the cutting 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 multiple upper cutters arranged at intervals on the upper knife shaft; the lower knife assembly 122 includes a lower knife shaft and multiple lower cutters arranged at intervals on the lower knife shaft; the upper cutters and the lower cutters correspond to each other one by one; a cutting drive assembly 123, which connects the upper knife shaft and the lower knife shaft, and can drive the upper knife shaft and the lower knife shaft to rotate, thereby making the upper cutter and the lower cutter rotate synchronously to achieve cutting; the insulating film strip passes between the upper knife assembly 121 and the lower knife assembly 122, and the upper cutter and the lower cutter cooperate to cut the insulating film strip into multiple narrow strips.

[0060] Reference Figure 4 and Figure 6 In the illustrated embodiment, the upper knife assembly 121 includes two upper cutting knives, and the lower knife assembly 122 includes two lower cutting knives. The insulating film strip passes through the upper knife assembly 121 and the lower knife assembly 122 and is divided into three narrow strips.

[0061] It should be noted that, on the upper knife shaft, multiple upper cutters are arranged at intervals along the width direction of the insulating film strip; similarly, on the lower knife shaft, multiple lower cutters are also arranged at intervals along the width direction of the insulating film strip. At the same time, the spacing between two adjacent cutters is equivalent to the width of the required narrow strip.

[0062] Among them, the upper cutting knife and the lower cutting knife can be circular knives, which are mounted on corresponding knife shafts; the knife shaft rotates around its own central axis under the drive of the slitting drive component 123, so that the circular knife thereon rotates with it, realizing continuous and stable cutting.

[0063] Among them, the slitting drive assembly 123 can adopt a servo motor. In one embodiment, the slitting drive assembly 123 can include two groups of servo motors, which are respectively connected to the upper knife shaft and the lower knife shaft to independently drive the upper knife shaft or the lower knife shaft to rotate. In another embodiment, the slitting drive assembly 123 can only include one group of servo motors, which is connected to one of the knife shafts; at the same time, the upper knife shaft and the lower knife shaft are connected by a linkage mechanism 126; in this way, the slitting drive assembly 123 drives the corresponding knife shaft to rotate, and through the linkage mechanism 126, it can drive the other knife shaft to rotate accordingly. The linkage mechanism 126 can adopt a synchronous pulley assembly, a gear assembly, etc., which can cooperate to achieve linkage, and the specific application is not limited.

[0064] Of course, in other embodiments, the insulating film slitting mechanism 120 may also be composed of a plurality of independent cutting components, which are arranged at intervals along the width direction of the insulating film strip to cut corresponding portions of the insulating film strip respectively; the details are not described here.

[0065] Furthermore, in order to ensure the slitting effect of the insulating film strip, the insulating film slitting mechanism 120 also includes: a front pressing component 124, which is arranged upstream of the slitting component; a rear pressing component 125, which is arranged downstream of the slitting component; after the insulating film strip passes through the front pressing component 124, it enters the slitting component; the slitting 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 material in the slitting component.

[0066] Through the front pressing assembly 124 and the rear pressing assembly 125, both ends of the material entering the slitting assembly can be tensioned, thereby making the material in a flat state, so that the slitting assembly can accurately cut the material.

[0067] Furthermore, since the material will be pulled and moved forward by the insulating film traction mechanism 140, the front pressure component 124 and the rear pressure component 125 can use pressure rollers. Since the rollers of the pressure rollers can rotate around their own roller axes, when the material is attached to the rollers and moved forward, the rollers can rotate to cooperate with the movement of the material, thereby avoiding the front pressure component 124 and the rear pressure component 125 contacting the surface of the material to interfere with the movement of the material or wear the surface of the material.

[0068] Of course, the front pressure assembly 124 and the rear pressure assembly 125 may also adopt other structures capable of supporting materials, as long as the materials can be flattened and tensioned on the front pressure assembly 124 and the rear pressure assembly 125, and this application does not make specific limitations.

[0069] In one embodiment, the front pressing assembly 124 and the rear pressing assembly 125 may each 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, so that the pressing roller of the front pressing assembly 124 can tension the material. Subsequently, the material enters the slitting assembly and is cut into multiple narrow materials. The multiple narrow materials pass through the rear pressing assembly 125 and move toward the insulating film cutting mechanism 130. The material also has a certain wrap angle on the pressing roller of the rear pressing assembly 125, so that the pressing roller of the rear pressing assembly 125 can tension the material. Figure 5 In the illustrated embodiment, the surfaces of the front pressing assembly 124 and the rear pressing assembly 125 that receive the materials are lower than the end surfaces of the materials cut by the slitting assembly; the materials enter the front pressing assembly 124 from top to bottom; then enter the slitting assembly from bottom to top; then enter the rear pressing assembly 125 from top to bottom; after passing through the rear pressing assembly 125, the materials move from bottom to top... In this way, the materials can be tensioned by the front pressing assembly 124 and the rear pressing assembly 125.

[0070] In order to better tension the material, the front pressing assembly 124 and / or the rear pressing assembly 125 includes: a first pressing roller 1241 and a second pressing roller 1242 arranged opposite to each other, and the insulating film strip or the insulating film 1 passes between the first pressing roller 1241 and the second pressing roller 1242; a pressing driving member 1243, which can drive the first pressing roller 1241 and the second pressing roller 1242 to move relative to each other to press the insulating film strip or the insulating film 1 therebetween.

[0071] Through the pressure driving member 1243, the first pressure roller 1241 and the second pressure roller 1242 can move relative to each other so as to be closer to or farther away from each other. In this way, when the first pressure roller 1241 and the second pressure roller 1242 are farther away from each other, it is convenient for the material to be threaded, so that the material can be manually pulled out of the front pressure component 124 or the rear pressure component 125 during the first operation or when changing the roll. When the equipment is in operation, the pressure driving member 1243 drives the first pressure roller 1241 and the second pressure roller 1242 to be closer to each other until the material is pressed between the two. On the one hand, the two pressure rollers pressing the material can better tension the material. On the other hand, since the material can be pressed by the two pressure rollers, the material does not need to wrap around the pressure rollers to ensure the tensioning effect. Refer to Figure 4 The material enters the front pressing assembly 124 horizontally and leaves the rear pressing assembly 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.

[0072] The pressing driving member 1243 may be a driving mechanism such as a cylinder or an electric cylinder. In one embodiment, one of the pressing rollers may be fixedly arranged, and the other pressing roller is connected to the pressing driving member 1243 and can press the fixed pressing roller under the drive 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 may include two cylinders, each connected to a pressing roller and capable of driving the corresponding pressing roller to move toward the other pressing roller.

[0073] Furthermore, the front pressure assembly 124 and / or the rear pressure assembly 125 also include a roller rotation driver (not shown), which is connected to the first pressure roller 1241 and / or the second pressure roller 1242, and can drive the corresponding pressure roller to actively rotate, thereby promoting the material conveying. Among them, the roller rotation driver can adopt a driving component such as a motor, which drives the pressure roller to rotate, drives the material passing around the pressure roller to be transported forward, thereby avoiding the friction of the pressure roller surface with the material. It is easy to think that the roller rotation driver can be connected to only one of the pressure rollers. Since the two pressure rollers are against each other during use, the actively rotating pressure roller will drive the other pressure roller to rotate. Similarly, the roller rotation driver can also drive the two pressure rollers to rotate synchronously at the same time.

[0074] In order to obtain the insulating film 1 of a desired length, the insulating film cutting mechanism 130 includes: a first cutter 131 and a first cutter driving member 132 ; the first cutter driving member 132 is connected to the first cutter 131 and can drive the first cutter 131 to move toward the insulating film 1 .

[0075] In one embodiment, the first cutter 131 is a long cutter having a certain length along the width direction of the insulating film strip, and can cut all the narrow strips cut at the same time. In other embodiments, the first cutter 131 can include multiple narrow cutters, which can cut each narrow strip separately. This application does not limit this.

[0076] The first cutter drive 132 can be a drive mechanism such as a cylinder or an electric cylinder. The plurality of narrow strips cut out pass through the edge of the first cutter 131. After the required length is passed, the first cutter drive 132 drives the first cutter 131 to approach and cut the narrow strips.

[0077] Furthermore, the insulating film cutting mechanism 130 also includes a first cutter avoidance driving component 133, which is connected to the first cutter 131 and can drive the first cutter 131 to approach or move away from the cutting station; when cutting the insulating film 1, the first cutter 131 is in the cutting station, and the first cutter driving component 132 drives the first cutter 131 to approach to cut the insulating film 1; after the cutting is completed, the first cutter driving component 132 drives the first cutter 131 away from and releases the insulating film 1; then, the first cutter avoidance driving component 133 drives the first cutter 131 away from the cutting station to expose the free end of the insulating film 1.

[0078] It should be explained that the cutting station is the station where the first cutter 131 cuts the material. When the insulating film traction mechanism 140 pulls the material downstream, the first cutter 131 is in the cutting station, and the blade end is facing the material. After the material is pulled out to the required length, the first cutter drive 132 drives the first cutter 131 to approach the cutting material. Subsequently, the insulating film traction mechanism 140 can continue to pull the material downstream to pull the material to the required position (that is, the insulating film loading station). At the same time, the first cutter avoidance drive 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 traction mechanism 140 can extract the free end, and then pull the material downstream to start a new round of material preparation. After the insulating film traction mechanism 140 extracts the free end of the material, the first cutter avoidance drive 133 can drive the first cutter 131 close to the cutting station for a new round of cutting.

[0079] The first cutter avoidance drive member 133 may be a drive mechanism such as a cylinder or an electric cylinder. The first cutter 131 may be arranged at the output end of the first cutter avoidance drive member 133, and the first cutter 131 may be arranged at the output end of the first cutter drive member 132. Alternatively, the first cutter 131 may be arranged at the output end of the first cutter drive member 132, and the first cutter drive member 132 may be arranged at the output end of the first cutter avoidance drive member 133.

[0080] When 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 feeding, in one embodiment, the first cutter avoidance driving member 133 can drive the first cutter 131 to move along the extension direction of the material and away from the insulating film traction mechanism 140; for example, referring to Figure 4 In the illustrated embodiment, the insulating film pulling mechanism 140 pulls the material from left to right. After cutting, the first cutter avoidance driving member 133 drives the first cutter 131 to move from right to left to expose the free end of the insulating film 1.

[0081] Furthermore, the insulating film cutting mechanism 130 also includes a cutter guide assembly, which is arranged upstream of the first cutter 131; the cutter guide assembly includes: a guide plate 134, used to receive 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 strip; any insulating film 1 passes between two guide bodies 135, and the two guide bodies 135 can limit the position of the passed insulating film 1.

[0082] It is easy to understand that after the insulating film strip is cut, multiple narrow strips are independent of each other. Due to the change in tension on the strips, these narrow strips are easily displaced; if there are displaced narrow strips, when the insulating film cutting mechanism 130 finally cuts the insulating film 1, the cut insulating film 1 may not have the correct pattern, which is easy to produce waste. For this reason, a cutter guide assembly is provided, and the guide body 135 is used to limit and guide each narrow strip to run correctly, so as to ensure the cutting effect of the insulating film 1.

[0083] Reference Figure 3 , Figure 7 and Figure 8 , the guide plate 134 may be a horizontal receiving plate, and the guide body 135 may be a protrusion disposed on the guide plate 134. When the insulating film material strip is divided into three, four guide bodies 135 are disposed on the guide plate 134 along the width direction of the insulating film material strip, 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. When a narrow material strip passes through a channel, the two guide bodies 135 disposed opposite to each other will "clamp" the narrow material strip, thereby limiting the position of the narrow material strip; at the same time, the channel will guide the material strip to move only along the running direction, thereby limiting the position state of each narrow material strip.

[0084] In order to pull the material to move downstream, the insulating film traction mechanism 140 includes: a traction member 141 and a traction drive assembly 142; the traction drive assembly 142 is connected to the traction member 141 and can drive the traction member 141 to move downstream along the first direction.

[0085] The traction member 141 may be a clamp, a suction cup or other extraction mechanism, as long as the free end of the material can be extracted. The traction drive assembly 142 may be an electric cylinder, a linear module or other drive mechanism. Figure 3 and Fig. 9 The main body of the traction drive assembly 142 extends along the first direction, that is, the left-right direction as 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 and gradually pull out the material of the required length.

[0086] Furthermore, the insulating film traction mechanism 140 also includes: a first auxiliary component 143, which is arranged downstream of the insulating film cutting mechanism 130; the first auxiliary component 143 includes: a first support plate 1431, used to support the cut insulating film 1; a first pressure block 1432 and a first auxiliary driving member 1433, the first auxiliary driving member 1433 is connected to the first pressure block 1432, and can drive the first pressure block 1432 to approach or move away from the first support plate 1431; wherein, the traction drive component 142 drives the traction member 141 to pull the insulating film 1 through the first auxiliary component 143; after pulling out a predetermined length of the insulating film 1, the first auxiliary driving member 1433 drives the first pressure block 1432 to approach and press against the first support plate 1431, thereby pressing the insulating film 1 on the first support plate 1431.

[0087] In actual use, the length of the finished insulating film 1 may be very long; in this case, after the insulating film 1 is cut, the broken end will naturally droop due to the loss of tension, which may cause the material to wrinkle or fold. This will affect the subsequent handling or use of the material. To this end, by setting the first auxiliary component 143, the broken end of the insulating film 1 can be clamped; at the same time, since the traction 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; then, the traction drive component 142 continues to drive the traction member 141 to move downstream, which can tension the insulating film 1, so that the insulating film 1 is straightened and tightened between the traction member 141 and the first auxiliary component 143.

[0088] It should be added that, in order to prevent the end of the cut end of the insulating film 1 from shifting after it is cut, it is preferred that the first pressing block 1432 presses the insulating film 1 on the first supporting plate 1431 before the insulating film cutting mechanism 130 cuts the insulating film 1. Specifically, after the insulating film 1 of the required length is pulled out, the pulling member 141 stops moving, and the first auxiliary driving member 1433 drives the first pressing block 1432 to approach and press against the first supporting plate 1431; after pressing the insulating film 1, the insulating film cutting mechanism 130 cuts the insulating film 1...

[0089] In order to transport the cut finished insulating film 1 to the insulating film loading station, so as to facilitate the receiving platform 310 to receive it. In one embodiment, a traction drive component 142 can be set to drive the traction member 141 to pull out the required length of the material, and the material is at the insulating film loading station; at this time, the insulating film cutting mechanism 130 cuts the insulating film 1, and the insulating film 1 can fall on the receiving platform 310 and be transported away by the receiving platform. For example, at the insulating film loading station, the receiving platform 310 is below the traction member 141; in this way, the traction member 141 can directly pull out the material on the receiving platform 310 under the drive of the traction drive component 142.

[0090] In another embodiment, the insulating film loading station can be located downstream of the insulating film cutting mechanism 130 and farther away from the insulating film cutting mechanism 130 to prevent the mechanical structure from affecting the accurate reception of the material by the receiving platform 310. 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 to completely guide the material to the insulating film loading station and place it on the receiving platform 310.

[0091] 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 and press against the first supporting plate 1431, thereby pressing the broken end of the material; after the insulating film cutting mechanism 130 cuts the insulating film 1, the traction driving component 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 loading station, the first pressing block 1432 and the first supporting plate 1431 need to clamp the material and move downstream with the traction member 141. For this purpose, refer to Fig. 9 The insulating film traction mechanism 140 also includes a first auxiliary driving component 144; the first auxiliary driving component 144 is connected to the first auxiliary component 143 and can drive the first auxiliary component 143 to move along the first direction.

[0092] In actual use, after the traction member 141 and the first auxiliary component 143 respectively control one end of the insulating film 1, the traction drive component 142 can drive the traction member 141 to move downstream, and the first auxiliary drive component 144 can drive the first auxiliary component 143 to move upstream, thereby tensioning the insulating film 1, and then the first auxiliary drive component 144 reversely drives the first auxiliary component 143 to move downstream with the traction member 141; or, the traction drive component 142 can drive the traction member 141 to move downstream, and after tensioning the insulating film 1, the first auxiliary drive component 144 also drives the first auxiliary component 143 to move downstream; thus, the traction member 141 and the first auxiliary component 143 cooperate to transport the insulating film 1 to the insulating film loading station so that the material receiving platform 310 can receive the insulating film 1.

[0093] The first auxiliary drive assembly 144 may be a drive member such as an electric cylinder or a linear module.

[0094] In addition, the insulating film loading device 100 also includes a guide mechanism 150; the guide mechanism 150 is arranged downstream of the insulating film slitting mechanism 120 and upstream of the insulating film cutting mechanism 130; the guide mechanism 150 includes: a guide platform 151, used to receive the slit insulating film 1; a plurality of guide blocks 152, which are arranged on the guide platform 151 at intervals along the width direction of the insulating film strip; any insulating film 1 passes between two guide blocks 152, and the two guide blocks 152 can limit the position of the insulating film 1.

[0095] The structure of the guide mechanism 150 is similar to that of the cutter guide assembly. The guide blocks 152 arranged at intervals form a channel and limit the position and position state of the material, so as to facilitate accurate material conveying and improve the accuracy of material preparation.

[0096] Reference Figure 4 and Fig.10 , the figure shows a structure of a guide mechanism 150, wherein the guide block 152 is a column block, and there are multiple guide blocks 152 along the width direction of the insulating film strip; for example, when the insulating film strip is divided into three, there are four guide blocks 152 along the width direction of the insulating film strip. Further, in order to better define the position state of the material, multiple rows of guide blocks 152 can be set along the running direction of the material, thereby guiding the material to run forward along the defined position.

[0097] For the busbar feeding device 200, similar to the insulating film feeding device 100, a handling device can be used to directly carry the finished busbar 2 to the busbar feeding station. Alternatively, the busbar feeding device 200 can use a busbar preparation device, through which a busbar material strip that does not meet the specifications can be prepared into a busbar that meets the specifications.

[0098] Reference Fig.11 The busbar preparation device includes: a busbar unwinding mechanism 210, used to release the busbar 2; a busbar cutting mechanism 220, which is arranged downstream of the busbar unwinding mechanism 210 and can cut the busbar 2; a busbar pulling mechanism 230, which can extract the busbar 2 and pull the busbar 2 to move downstream along the first direction; the busbar 2 is pulled by the busbar pulling mechanism 230 and passes through the busbar cutting mechanism 220. After passing through a predetermined length, the busbar cutting mechanism 220 cuts the busbar 2.

[0099] The busbar unwinding mechanism 210 is similar to the insulating film unwinding mechanism 110, and also includes an unwinding shaft, on which the busbar strip is sleeved; the unwinding shaft is driven by a servo motor and can actively rotate and release the busbar strip. A plurality of rollers are also provided downstream of the unwinding shaft to tighten the busbar strip and guide the busbar strip to move toward the downstream mechanisms.

[0100] The busbar cutting mechanism 220 is similar to the insulating film cutting mechanism 130, and includes: a second cutter 221 and a second cutter driving member 222; the second cutter driving member 222 is connected to the second cutter 221 and can drive the second cutter 221 to move toward the busbar 2. The blade end of the second cutter 221 faces the material, and after the material is pulled out to a desired length, the second cutter driving member 222 can drive the second cutter 221 to approach and cut the material.

[0101] Furthermore, the busbar cutting mechanism 220 also includes a second cutter avoidance driving member 223, which is connected to the second cutter 221 and can drive the second cutter 221 to approach or move away from the cutting station; when cutting the busbar 2, the second cutter 221 is in the cutting station, and the second cutter driving member 222 drives the second cutter 221 to approach to cut the busbar 2; after the cutting is completed, the second cutter driving member 222 drives the second cutter 221 away from and releases the busbar 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 busbar 2.

[0102] It needs to be explained that the cutting station for the busbar cutting mechanism 220 is the cutting station for the busbar 2, and the cutting station for the insulating film cutting mechanism 130 in the above text 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 referred to as cutting stations. When the cutting station is mentioned in the text, it will be clear whether it is for the busbar 2 or the insulating film 1.

[0103] Likewise, the second cutter avoidance driving member 223 is similar to the first cutter avoidance driving member 133, and will not be described in detail herein.

[0104] Furthermore, the busbar cutting mechanism 220 also includes a limiting assembly, which is arranged upstream of the second cutter 221; the limiting assembly includes two limiting rods 224 arranged at intervals along the width direction of the busbar 2; the busbar 2 passes between the two limiting rods 224, and the two limiting rods 224 can limit the position of the passing busbar 2.

[0105] 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 and further limit the position of the bus bar 2.

[0106] Furthermore, in order to facilitate the adjustment of the position of the limit rod 224 so as to adjust the running position of the busbar 2, the limit assembly also includes: a guide rod 225, extending along the width direction of the busbar 2, and two limit rods 224 are slidably arranged on the guide rod 225; an adjusting member 226, connecting the two limit rods 224 and enabling the two limit rods 224 to move along the guide rod 225; wherein, a baffle 227 is provided at one end of the guide rod 225 away from the adjusting member 226, and an elastic member 228 is provided between the baffle 227 and the two limit rods 224; when the two limit rods 224 move toward the baffle 227, the elastic member 228 is compressed.

[0107] Reference Fig.12, the guide rod 225 can be set 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 that the second cutter 221 can accurately cut the material, and the busbar pulling mechanism 230 can accurately pull the material. The two limit rods 224 can be independently sleeved on the guide rod 225; in order to avoid the change of the spacing 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 set 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 adjustment 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 force generated by the compression resists the limit rod 224, and cooperates with the force of the adjustment member 226 in another direction to make the limit rod 224 stay 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 cooperate with the force applied to the limit rod 224 by the adjustment member 226, so that the limit rod 224 stays in the desired position.

[0108] The adjusting member 226 may be a micrometer, a hand-adjustable rod or the like, as long as it can apply force to the limit rod 224 and adjust the position of the limit rod 224 , and this application does not make any limitation thereto.

[0109] The busbar traction mechanism 230 is similar to the insulating film traction mechanism 140 , and also includes: a traction member 231 and a traction drive assembly 232 ; the traction drive assembly 232 is connected to the traction member 231 , and can drive the traction member 231 to move downstream along a first direction.

[0110] The traction member 231 is similar to the traction member 141 , and the traction drive assembly 232 is similar to the traction drive assembly 142 , and the details are not repeated here.

[0111] Furthermore, the busbar traction mechanism 230 also includes a second auxiliary component 233, which is arranged downstream of the busbar cutting mechanism 220; the second auxiliary component 233 includes: a second support plate 2331, used to support the corresponding busbar 2; a second pressure block 2332 and a second auxiliary driving member 2333, the second auxiliary driving member 2333 is connected to the second pressure block 2332, and can drive the second pressure block 2332 to approach or move away from the second support plate 2331; wherein, the traction drive component 232 drives the traction member 231 to pull the busbar 2 through the second auxiliary component 233; after pulling out the busbar 2 of a predetermined length, the second auxiliary driving member 2333 drives the second pressure block 2332 to approach and press against the second support plate 2331, thereby pressing the busbar 2 on the second support plate 2331.

[0112] Furthermore, the busbar pulling mechanism 230 further includes a second auxiliary driving component 234 ; the second auxiliary driving component 234 is connected to the second auxiliary component 233 , and can drive the second auxiliary component 233 to move along the first direction.

[0113] Through the second auxiliary component 233, the cut busbar 2 can be tensioned in cooperation with the traction member 231; further, through the second auxiliary drive component 234, the traction drive component 232 can be cooperated, and after the busbar 2 is tensioned, the traction member 231 and the second auxiliary component 233 move the finished busbar 2 to the busbar loading station.

[0114] It can be understood that the second auxiliary component 233 is similar to the first auxiliary component 143, and the second auxiliary drive component 234 is similar to the first auxiliary drive component 144, and the details are not repeated here.

[0115] Continue to refer Figure 1 or Figure 2 In addition to being composed of the busbar 2 and the insulating film 1, the second busbar 2b has another feature, that is, one of the two ends of the busbar 2 protruding from the insulating film 1 is tilted upward to facilitate connection to the junction box.

[0116] To this end, the busbar preparation device also includes a busbar bending mechanism 240; after the material receiving platform 310 receives the busbar 2, the end of the busbar 2 protrudes from the material receiving platform 310; the busbar bending mechanism 240 is arranged on one side of the material receiving platform 310, facing the protruding end of the busbar 2; the busbar 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 to move toward the protruding end of the busbar 2, thereby folding the busbar 2.

[0117] The busbar bending mechanism 240 can be arranged at one end of the busbar loading station, facing the end of the pulled-out busbar 2; at this time, after the busbar 2 is placed on the receiving platform 310, its end can be folded by the busbar bending mechanism 240.

[0118] Alternatively, the busbar bending mechanism 240 can be set at one end of the hot pressing station, facing the busbar 2 protruding from the end of the docking platform 310; at this time, the hot pressing device 400 hot presses the busbar 2 and the insulating film 1, and the busbar bending mechanism 240 folds the end of the busbar 2.

[0119] Alternatively, the busbar bending mechanism 240 can be set at one end of the insulating film loading station, opposite to the end of the pulled out busbar 2; at this time, the receiving platform 310 first receives the busbar 2, and then moves to the insulating film loading station to receive the insulating film 1; and the busbar bending mechanism 240 folds the end of the busbar 2.

[0120] Alternatively, the busbar bending mechanism 240 can be set up with other workstations. After the receiving platform 310 receives the busbar 2, it moves to the workstation so that the busbar bending mechanism 240 is directly connected to the busbar 2 protruding from the end of the receiving platform 310, thereby realizing the folding of the end of the busbar 2.

[0121] In one embodiment, the material receiving platform 310 first receives the insulating film 1 and then receives the busbar 2, so that the busbar 2 is placed on the insulating film 1; when the material receiving platform 310 reaches the bending station, the busbar bending mechanism 240 as a whole is not higher than the busbar 2 protruding from the end of the material receiving platform 310; when the busbar 2 is in place, the bending drive member 242 drives the bending member 241 to move from bottom to top, and folds the end of the busbar 2 protruding outside the material receiving platform 310 upward, so that the end of the busbar 2 is tilted upward.

[0122] Of course, when the overlapping manner of the busbar 2 and the insulating film 1 is changed, the initial position of the busbar bending mechanism 240 will be adjusted accordingly, as long as the end of the busbar 2 is guaranteed to be tilted in a direction away from the insulating film 1 .

[0123] Furthermore, in order to ensure the folding effect, in one embodiment, the busbar bending mechanism 240 also includes a pressing assembly (not shown); before the bending member 241 folds the end of the busbar 2, the pressing assembly first presses the position of the busbar 2 to be folded and presses the busbar 2 on the material receiving platform 310; in this way, when the bending drive member 242 drives the bending member 241 to move toward the busbar 2, the bending member 241 can move along the pressing assembly, and then press the folded part on the pressing assembly, so as to press out a crease and ensure the stability of the raised end of the busbar 2.

[0124] In other embodiments, the busbar bending mechanism 240 can be set at one end of the hot pressing station, facing the busbar 2 protruding from the end of the material receiving platform 310; at this time, the hot pressing device 400 needs to press the busbar 2 and the insulating film 1 to achieve hot pressing; in this way, the hot pressing device 400 can be used as the "pressing component" in the above-mentioned embodiment; that is, the busbar 2 is pressed on the material receiving platform 310 by the hot pressing device 400, so as to facilitate the busbar bending mechanism 240 to fold the busbar 2.

[0125] It should also be added that when the insulating film loading device 100 includes an insulating film slitting mechanism 120, the insulating film loading device 100 can prepare multiple insulating films 1 at a time. For this purpose, the busbar loading device 200 can include multiple groups of busbar preparation devices to prepare multiple busbars 2 at a time, thereby accelerating the efficiency of the busbar hot pressing machine in preparing the second busbar 2b.

[0126] Of course, in actual design of the structure, each group of busbar preparation devices may include an independent busbar unwinding mechanism 210 , a busbar cutting mechanism 220 , a busbar pulling mechanism 230 and a busbar bending mechanism 240 .

[0127] Alternatively, in order to simplify the structure, the busbar cutting mechanism 220 may include only one set of second cutters 221 and second cutter driving members 222; in this case, the multiple busbars released by the multiple sets of busbar unwinding mechanisms 210 are arranged side by side along the width direction of the busbar, and the second cutter 221 has a certain length along the width direction of the busbar, and can cut all the busbar strips at the same time.

[0128] Similarly, the busbar traction mechanism 230 may include only a set of second auxiliary components 233 and a second auxiliary drive component 234; at this time, the second support plate 2331 of the second auxiliary component 233 has a certain length along the width direction of the busbar, and can simultaneously support all the busbars 2; similarly, the second pressure block 2332 of the second auxiliary component 233 has a certain length along the width direction of the busbar, and can simultaneously press all the busbars 2 on the second support plate 2331.

[0129] In addition, when the insulating film feeding device 100 includes an insulating film slitting mechanism 120, since the final finished insulating film 1 is cut from an insulating film strip, in order to prevent the narrow strips after slitting from affecting the unslit insulating film strips due to the long spacing, causing the insulating film strips to tear or shift, the adjacent relationship of the narrow strips is actually very close to the overall state of the insulating film strips, that is, the spacing between two adjacent narrow strips is very small. However, for multiple sets of busbar feeding devices 200, due to the space occupied and layout of the equipment, the spacing between two adjacent finished busbars 2 will be relatively large. In order to facilitate the receiving of multiple insulating films 1 and multiple bus bars 2 with inconsistent spacing, the material receiving platform 310 includes: multiple material receiving platforms 311, any material receiving platform 311 extends along the first direction and has a certain length; a variable pitch drive component 312, which can drive the multiple material receiving platforms 311 to move relative to each other to adjust the spacing between two adjacent material receiving platforms 311; when the material receiving platform 310 is driven by the material receiving drive component 320, it moves to the insulating film loading device 100 to receive the insulating film 1, and the distance between the two adjacent material receiving platforms 311 is a first distance; when the material receiving platform 310 moves to the bus bar loading device 200 to receive the bus bar 2, the distance between the two adjacent material receiving platforms 311 is a second distance; the second distance is greater than the first distance.

[0130] Therefore, before the receiving platform 310 receives the insulating film 1 at the insulating film loading station, the variable pitch drive assembly 312 can drive the multiple receiving platforms 311 to approach each other to a narrower spacing, so that each receiving platform 311 can receive an insulating film 1. Before the receiving platform 310 receives the bus bar 2 at the bus bar loading station, the variable pitch drive assembly 312 can drive the multiple receiving platforms 311 to move away from each other to a wider spacing, so that each receiving platform 311 can receive a bus bar 2.

[0131] In one embodiment, the variable pitch drive assembly 312 may include a plurality of variable pitch drive members 3121, and the variable pitch drive members 3121 are connected to the receiving platform 311 in a one-to-one correspondence. Fig.13 When the pitch needs to be changed, the pitch-changing driving member 3121 drives the corresponding receiving platform 311 to move closer to or farther away from the adjacent receiving platform 311. The pitch-changing driving member can be a driving member such as an electric cylinder or a linear module.

[0132] 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 piece 3122 is provided between two adjacent receiving platforms 311 , and the receiving platforms 311 can move along the corresponding connecting piece 3122 ; the variable pitch driving piece 3121 is connected to the sidemost receiving platform 311 . In this way, when it is necessary to adjust to the second distance, the variable-pitch driving member 3121 drives the most lateral material receiving platform 311 to move outward, and when the material receiving platform 311 moves to the end of the connecting member 3122, it will drive an adjacent material receiving platform 311 to move outward; when the adjacent material receiving platform 311 moves to the end of the corresponding connecting member 3122, it will drive the next adjacent material receiving platform 311 to move outward… When it is necessary to adjust to the first distance, the variable-pitch driving member 3121 drives the most lateral material receiving platform 311 to move toward the adjacent material receiving platform 311, and moves to one end of the connecting member 3122 connected to the adjacent material receiving platform 311, or moves to the two material receiving platforms 311 against each other, and the two material receiving platforms 311 can move toward the next adjacent material receiving platform 311… Among them, the connecting member 3122 can adopt a connecting mechanism such as a connecting rod or a cam structure.

[0133] For example, refer 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 platforms 311 to change their positions; in this case, the variable pitch drive assembly 312 also includes a plurality of guide members 3123, and each guide member 3123 is arranged radially; in this way, when it is necessary to adjust to the second distance, the variable pitch drive member 3121 drives the receiving platform 311 to move along the guide member 3123 in the radial direction, so that each receiving platform 311 is separated from each other; when it is necessary to adjust to the first distance, the variable pitch drive member 3121 drives the receiving platform 311 to move along the guide member 3123 in the contraction direction, so that each receiving platform 311 is close to each other. Among them, the guide member 3123 can be a guide member such as a guide rod, a guide rail, a cam structure, etc.

[0134] In summary, the actual structure of the variable pitch drive assembly 312 can be varied, as long as the relative position of each receiving table 311 can be changed, and this application does not make any specific limitations.

[0135] Furthermore, the plurality of receiving platforms 311 are arranged side by side along the second direction; the variable pitch drive assembly 312 can drive the plurality of receiving platforms 311 to move relative to each other along the second direction; the first direction and the second direction are perpendicular to each other and form a horizontal plane.

[0136] 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 busbar pulling mechanism 230 pulls the busbar 2. By pulling the insulating film 1 and the busbar 2 out along the first direction, the insulating film 1 and the busbar 2 finally obtained extend along the first direction, so that the receiving platform 311 extending along the first direction directly receives the insulating film 1 and the busbar 2, so that the two are superimposed together and convenient for subsequent hot pressing.

[0137] It should be added that, in other embodiments, the direction in which the insulating film traction mechanism 140 pulls the insulating film 1, the direction in which the bus bar traction mechanism 230 pulls the bus bar 2, and the extension direction of the material receiving table 311 may also be different. It is only necessary to adjust the direction of the finished insulating film 1, the finished bus bar 2 or the material receiving table 311 accordingly when loading the material, so that the material receiving table 311 can receive the material.

[0138] Correspondingly, the second direction is a direction perpendicular to the first direction in the horizontal plane. Specifically, on the receiving platform 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 the arrangement direction of multiple insulating films 1 or multiple bus bars 2.

[0139] By arranging a plurality of receiving platforms 311 along the second direction, each receiving platform 311 can conveniently receive a corresponding insulating film 1 or bus bar 2 .

[0140] Furthermore, by driving the plurality of receiving platforms 311 to move relative to each other in the second direction through the variable pitch drive assembly 312 , the spacing between the receiving platforms 311 can be quickly adjusted.

[0141] In addition, since the insulating film 1 and the bus bar 2 are sheet materials, they are easy to separate from the receiving platform 311. For this purpose, an air hole 313 can be opened on the receiving platform 311. The air hole 313 is connected to a negative pressure device. The negative pressure device can evacuate the air hole 313 to form a negative pressure inside the air hole 313, thereby sucking the insulating film 1 on the receiving platform 311.

[0142] Reference Fig.13 , Fig.14 or Fig.15 Along the first direction (vertical direction in the figure), the receiving platform 311 is provided with a plurality of air holes 313 arranged at intervals, so that the finished insulating film 1 and the bus bar 2 extending along the first direction can be stably attracted. If the finished insulating film 1 and the bus bar 2 are wider, the receiving platform 311 can also be provided with a plurality of air holes 313 along the second direction (left-right direction in the figure) to better attract the material.

[0143] When multiple groups 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 group of heating mechanisms 410 , which can hot press each group of insulating films 1 and bus bars 2 in sequence under the drive of the hot pressing driving component 420 .

[0144] 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 that drives 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 assembly 420 drives the heating mechanism 410 to move from top to bottom, pressing against the material receiving platform 310 to achieve hot pressing.

[0145] When the hot pressing station overlaps with other stations, the devices corresponding to the other stations are in motion, and the hot pressing device 400 needs to avoid the hot pressing station. For this reason, the hot pressing drive component 420 also includes another drive component that drives the heating mechanism 410 away from the hot pressing station. Fig.16 The hot pressing driving component 420 includes a driving component 1 421 for driving the heating mechanism 410 to move in a vertical direction, and a driving component 2 422 for driving the heating mechanism 410 to move in a horizontal direction; when hot pressing is required, the driving component 2 422 first 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 1 421 drives the heating mechanism 410 to press against the material receiving platform 310 to achieve hot pressing; when the hot pressing is completed, the driving component 2 422 drives the heating mechanism 410 away from the hot pressing station to facilitate the action of other mechanisms.

[0146] In another embodiment, the hot pressing device 400 may include a plurality of groups of heating mechanisms 410 arranged side by side along the second direction; the heating mechanisms 410 correspond to the receiving platform 311 one by one, so as to respectively perform hot pressing on a group of finished insulating films 1 and bus bars 2. It should be noted that in this embodiment, two adjacent groups of heating mechanisms 410 may be arranged at a first distance, or at a second distance, or at other distances, as long as the variable pitch drive member 3121 can drive the receiving platform 311 to adjust to correspond to the heating mechanism 410 when the receiving platform 311 carrying the finished insulating film 1 and bus bars 2 arrives at the hot pressing station.

[0147] It should be explained that the main purpose of the insulating film 1 is to isolate the bus bar 2 from the battery cell 11. At the same time, it is also necessary to assist in the connection between the bus bar 2 and the battery cell 11 to avoid the position shift of the bus bar 2. Therefore, the bus bar 2 and the insulating film 1 need to be hot pressed together to ensure that the relative positions of the two are fixed; then, when connecting with the battery string 10, the insulating film 1 part will be hot pressed onto the battery string 10 again to further define the connection relationship.

[0148] Specifically, in order to avoid short circuit between busbar 2 and battery string 10 and to ensure that the positions of busbar 2 and battery string 10 are fixed, the insulating film 1 is made of special material, such as ECPCE material; its characteristic is that during hot pressing, the hot pressing surface of the material will melt, thereby facilitating the bonding of busbar 2 and insulating film 1; and, as the material further melts, the other surface of insulating film 1 will melt and bond with battery string 10. In other words, after the busbar 2 is transferred to the battery string 10, a hot pressing device will further hot press the busbar 2 and insulating film 1, so that the other hot pressing surface of insulating film 1 melts and bonds with battery string 10, thereby ensuring that the busbar 2 and battery string 10 are insulated and fixed.

[0149] The heating mechanism 410 is mainly used to provide heat to achieve hot melting of the insulating film 1. To this end, the heating mechanism 410 includes a heating block 411, which is extended along the first direction; in this way, the heating block 411 can efficiently hot press the finished insulating film 1 and the busbar 2. The heating block 411 is mainly made of a material with good thermal conductivity, such as copper; a heating rod is provided in the heating block 411; when the heating rod is activated, the heating block 411 can be heated; as the heating block 411 abuts against or approaches the material, the heat on the heating block 411 can be transferred to the material.

[0150] Furthermore, 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 also includes a plurality of pressing pins 412, which are arranged on the heating block 411 at intervals along the first direction; each pressing pin 412 penetrates the heating block 411 and can move in the heating block 411; one end of the pressing pin 412 penetrating the top surface of the heating block 411 has a stopper, which can prevent the pressing pin 412 from detaching from the heating block 411; one end of the pressing pin 412 penetrating the bottom surface of the heating block 411 has a pressure head, Used to abut against the bus bar 2 and the insulating film 1; an elastic part 413 is sleeved on the pressing needle 412; one end of the elastic part 413 abuts against the bottom surface of the heating block 411, and the other end abuts against the pressing head; during hot pressing, the hot pressing drive component 420 drives the heating mechanism 410 to approach the material receiving platform 310, and the pressing needle 412 first abuts against the material receiving platform 310; as the hot pressing drive component 420 continuously drives the heating mechanism 410 to approach the material receiving platform 310, the pressing needle 412 gradually penetrates the top surface of the heating block 411, and the elastic part 413 is compressed.

[0151] Reference Fig.16 and Fig.17 , the receiving platform 310 transports the finished insulating film 1 and bus bar 2 to the hot pressing station, and the heating mechanism 410 is suspended above the receiving platform 310, facing the insulating film 1 and bus bar 2. Subsequently, the hot pressing drive assembly 420 drives the heating mechanism 410 to move from top to bottom, and the pressing needle 412 first presses against the material; the hot pressing drive assembly 420 continues to drive the heating mechanism 410 to move downward; the heating block 411 continues to approach the material, and the end of the pressing needle 412 with the pressing head always presses against the material and does not move, while the end of the pressing needle 412 with the stopper gradually passes through the heating block 411; the elastic member 413 is compressed, and the reverse force generated by the deformation of the elastic member 413 acts on the pressing head, so that the pressing needle 412 always presses the material tightly.

[0152] By pressing the material with the pressing needle 412 , the position of the material can be further limited to ensure that the heating block 411 heats the material accurately.

[0153] It is easy to imagine that when the finished insulating film 1 and busbar 2 are long, a set of heating mechanisms 410 uses only one heating block 411, and the heating block 411 needs to be set very long. However, a long heating block may have temperature differences at different positions, which will affect the final hot pressing effect. Fig.16 A group of heating mechanisms 410 may include multiple heating blocks 411, and the multiple 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 for heating, which can ensure the temperature of each heating block 411.

[0154] In order to remove the hot-pressed insulating film 1 and busbar 2 on the material receiving platform 310, the busbar hot-pressing integrated machine provided in the present application also includes a conveying device 500 for transferring the hot-pressed busbar 2 and insulating film 1; the conveying device 500 includes: a conveying and extracting member 510 and a conveying drive mechanism 520, the conveying drive mechanism 520 is connected to the conveying and extracting member 510, and can drive the conveying and extracting member 510 to extract the hot-pressed busbar 2 and insulating film 1 from the material receiving platform 310, and transfer the hot-pressed busbar 2 and insulating film 1 outward.

[0155] It should be added that, in order to cooperate with the handling device 500 in unloading, there can also be an unloading station on the movement path of the material receiving platform 310. Specifically, after the hot pressing is completed, the insulating film 1 and the busbar 2 are bonded together, and one end of the busbar 2 is tilted to form the second busbar 2b; then, the material receiving drive component 320 drives the material receiving platform 310 to transport the second busbar 2b to the unloading station, so that the conveying drive mechanism 520 drives the conveying extraction member 510 to receive the second busbar 2b at the unloading station; after the second busbar 2b is taken away, the material receiving drive component 320 can drive the material receiving platform 310 to the insulating film loading station or the busbar loading station to receive a new round of materials.

[0156] Of course, it is easy to imagine that the unloading station can also overlap with the hot pressing station, that is, after the hot pressing device 400 hot presses the material at the hot pressing station, the hot pressing device 400 is transferred, the material receiving platform 310 remains stationary, and the conveying device 500 moves to the hot pressing station to extract the second bus bar 2b on the conveying device 500.

[0157] Among them, the transport and extraction component 510 can adopt extraction components such as suction cups and clamps; the transport driving mechanism 520 can include two groups of driving components for driving the transport and extraction component 510 to move in the vertical direction and in the horizontal direction (the driving components can adopt driving components such as electric cylinders or linear modules). The driving component that drives the transport and extraction component 510 in the vertical direction can, when the transport and extraction component 510 reaches the unloading station, approach the material receiving platform 310 to receive the second bus bar 2b, and the driving component that drives the transport and extraction component 510 in the horizontal direction can drive the transport and extraction component 510 to move close to or away from the unloading station.

[0158] In addition, the busbar hot-pressing integrated machine provided in the present application further includes a buffer rack 600 for receiving the hot-pressed busbars 2 and insulating films 1 transported by the transport device 500 .

[0159] The cache rack 600 may be just a storage component, for example, the cache rack 600 may be a receiving platform capable of receiving the second type of bus bar 2b. Alternatively, the cache rack 600 may be a conveying component, for example, the cache rack 600 may be a conveyor belt assembly; the handling device 500 receives the second type of bus bar 2b from the receiving platform 310 and transfers it to the conveyor belt, and the conveyor belt moves forward to transport the second type of bus bar 2b, further optimizing the flow path of the material.

[0160] The present application also discloses a busbar hot pressing method, comprising the following steps:

[0161] The receiving device 300 moves to the insulating film feeding device 100 to receive the insulating film 1;

[0162] The receiving device 300 then moves to the bus bar feeding device 200 to receive the bus bar 2;

[0163] The busbar 2 is placed on the insulating film 1;

[0164] The material receiving device 300 then moves to the hot pressing device 400, and the hot pressing device 400 hot presses the bus bar 2 and the insulating film 1, so that the bus bar 2 and the insulating film 1 are bonded together;

[0165] The end of the bus bar 2 protrudes from the material receiving platform 310, and the bus bar 2 is folded by the bus bar bending mechanism 240 so that the protruding end of the bus bar 2 is tilted upward;

[0166] The receiving device 300 then moves to the transporting device 500 , and the transporting device 500 takes away the hot-pressed busbar 2 and the insulating film 1 .

[0167] The above description is only an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
