[0067] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0068] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0069] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0070] See attached Figures 1 to 3 As shown, a busbar preparation device includes a tape feeding mechanism A, an intermediate tape clamping mechanism B, a tape cutting mechanism C and a tape pulling mechanism D which are horizontally arranged in sequence from front to back in the conveying direction of the busbar 1.

[0071] The tape feeding mechanism A and the tape pulling mechanism D correspond to the front and rear ends of the busbar 1 in the transmission direction, respectively, and both act together on the busbar 1 to convey it backwards; the intermediate tape clamping mechanism B is used to position the pulled busbar 1 to cooperate with the tape cutting mechanism C, which is used to cut the busbar 1b (see Fig.19 ) and for the busbar 1a on the M side (see Fig. 20 , 21 ) for cutting and bending.

[0072] Among them, Fig.12 , 13 As shown, the tape cutting mechanism C includes a tape cutting module 2 for processing the F-side (or B-side) busbar 1b, and the tape cutting module 2 includes at least one set of first tape cutting components 5, and the first tape cutting components 5 include a positioning mold 3 and a cutting knife 4. The cutting knife 4 is driven by a first cylinder 53 and a first connecting rod group 54 to perform a lifting action relative to the positioning mold 3 to cut the busbar 1 located between the two. The first tape cutting components 5 can be set in two groups, one in front and one in the back, and the front and rear positions can also be adjusted to meet different cutting requirements of users.

[0073] like Figures 7 to 11 As shown, the tape cutting mechanism C further includes a tape cutting and bending module 6 for processing the M-side bus bar 1 a , and the tape cutting and bending module 6 includes a second tape cutting component 7 and a bending component 8 .

[0074] The second tape cutting assembly 7 includes a punching die 9 and a punching head 10 .

[0075] The horizontal cross-sectional shape of the punching head 10 is an hourglass shape that is symmetrically concave on both sides. The punching die 9 is provided with an hourglass-shaped punching notch 11 that matches the cross-sectional shape of the punching head 10, and the punching head 10 and the punching notch 11 are arranged opposite to each other in the upper and lower directions.

[0076] The punching head 10 is driven by the second cylinder 55 and the second connecting rod group 56 to move up and down toward the punching notch 11, cutting the bus bar 1a on the M side of the punching die 9, and punching out rounded corners at the front and rear cutting positions of the bus bar 1a on the M side through the hourglass-shaped structure design (see FIG. Fig.21 ). After cutting, the bending action is performed to make the end of the bus bar 1 after punching and bending easy to insert into the junction box, and the rounded corner (chamfered corner) design is more conducive to the bus bar 1 to be quickly and accurately inserted into the junction box. After the bus bar 1 is bent, the spacing action is performed.

[0077] The bending assembly 8 includes two positioning platforms 12 respectively arranged at the front and rear sides of the punching die 9. The two positioning platforms 12 are provided with slots 13 for the busbar 1 to pass horizontally. After the busbar 1 is punched and cut, it can be placed in the slots 13. A pressing sheet 14 is also provided corresponding to each positioning platform 12. The pressing sheet 14 is slidably arranged in the gap between the side of the punching die 9 and the positioning platform 12 in the vertical direction, and is driven by the third cylinder 57 to bend the end of the busbar 1 that passes through the slot 13 and is punched by the punching head 10.

[0078] Before punching, the pressing sheet 14 is located below the busbar 1. During punching, the pressing sheet 14 rises so that the end of the busbar 1 can be bent toward the side of the punching die 9 by the positioning platform 12 until the busbar 1 is bent to nearly 90 degrees. After the bending is completed, a spacing mechanism 22 can be used to separate and move out of the notch 13.

[0079] like Figures 4 to 6 As shown, the tape feeding mechanism A comprises a mounting frame 15, on which a tape threading guide portion 16, a clamping portion 17, a roller clamping portion 18 and a front end cutting portion 19 are arranged in sequence from front to back.

[0080] The belt threading guide 16 includes a limit block 20 and a supporting roller 21 . The former supports the bus bar 1 , and the latter guides and supports the bus bar 1 .

[0081] The clamping portion 17 includes a positioning seat 23 and a pressing mechanism 24 for pressing the busbar 1 passing through the positioning seat 23 onto the positioning seat 23 to prevent the busbar 1 from slipping or retreating in a non-tensioned state. The pressing mechanism 24 presses down the busbar 1 on the positioning seat 23 through the drive of the pressing cylinder 51.

[0082] The roller clamping portion 18 includes a pair of rollers 25 arranged vertically. The busbar 1 passes through the gap between the two rollers 25 and is clamped by the two rollers 25. One of the rollers is an active roller 25a, which is driven to clamp the busbar 1 backward together with the driven roller 25b to realize the supply of the rear end busbar 1 to the rear end.

[0083] After the entire busbar 1 is partially pulled out, the entire busbar 1 needs to be cut. For this purpose, the front end cutting portion 19 is also provided at the end of the mounting frame 15. The front end cutting portion 19 includes a threading limit block 26 and a front end cutting knife 27. The front end cutting knife 27 is driven by the front end cutting cylinder 52 and the third connecting rod group 58 to perform lifting motion to cut the busbar 1 that is passed through and extends out of the threading limit block 26.

[0084] The utility model adopts the force-increasing structure of the connecting rod group in many places (the force arm of the long rod is output to the short rod to achieve the force-increasing effect), and can save vertical space at the same time. The first connecting rod group 54 and the third connecting rod group 58 are used to increase the shearing force to ensure the shearing effect; the cutting knife 4 and the front cutting knife 27 can be abutted against the cutting surface by the spring, ensuring the accuracy of the cutting position.

[0085] Preferably, the belt feeding mechanism A is provided with two parallel and horizontally symmetrical groups, and the active rollers 25a on both sides are driven simultaneously through a synchronous belt assembly 28, so as to simultaneously drive the busbars 1 on both sides to clamp forward, i.e., the busbar 1b on the F side and the busbar 1a on the M side in the figure.

[0086] like Fig.12 , 13 As shown, the intermediate clamping mechanism B includes a first clamping jaw cylinder 29 and a pair of first clamping jaws 30 driven to open and close by the first clamping jaw cylinder 29. The first clamping jaws 30 are closed to clamp the bus bar 1 passing through this position, so that the cutting mechanism C can perform "secondary cutting" or "secondary cutting and bending" on the bus bar 1. Preferably, the opposite surfaces of the two first clamping jaws 30 can be provided with V-shaped notches to better clamp the bus bar 1.

[0087] Preferably, the spacing mechanism 22 is also included, and the intermediate clamping mechanism B is transmission-connected to the slide 31 of the spacing mechanism 22. The slide 31 is driven by the fourth cylinder 59 to move horizontally along the width direction of the busbar 1, and is used to laterally separate the busbar prepared by the cutting mechanism C to the required position for transportation and handling.

[0088] like Figures 22-24 As shown, the drawstring mechanism D comprises a mounting frame 32 , on which a hinge seat 33 is disposed, on which a pressing claw 34 is rotatably disposed, and a first end of the pressing claw 34 serves as a pressing end of the busbar 1 .

[0089] The mounting frame 32 is provided with a lifting portion 35 corresponding to the second end of the pressing claw 34. The lifting portion 35 is driven to lift the second end of the pressing claw 34, thereby driving the first end of the pressing claw 34 to press the busbar 1 downward. Fig.23 As shown, the lifting portion 35 is an inflated rubber film, and the inflated rubber film acts on the second end of the pressing claw 34, so that the first end of the pressing claw 34 presses down and clamps the busbar 1.

[0090] Preferably, an elastic member 36 (such as a spring) is provided on the mounting frame 32 corresponding to the first end of the pressing claw 34, and the elastic member 36 acts between the mounting frame 32 and the first end of the pressing claw 34 to keep the first end of the pressing claw 34 open when there is no air supply to the adhesive film.

[0091] like Figures 14 to 16As shown, it also includes a movable bracket 37 , handling hands 38 arranged in pairs on the movable bracket 37 , and a horizontal transfer platform 42 connected to the two handling hands 38 .

[0092] The movable bracket 37 includes a pair of parallel and spaced guide rails 43 , and the two transporting hands 38 are respectively disposed on sliders 40 of the two guide rails 43 , so that the transporting hands 38 can be translated along the length direction of the guide rails 43 through the sliders 40 .

[0093] The transport arm 38 includes a swing arm base plate 45 , a rotation drive mechanism 46 , a rotation arm 47 , a secondary arm 48 , a balance arm 49 , and a horizontal fixing seat 50 for fixing the horizontal transfer platform 42 .

[0094] The swing arm bottom plate 45 is fixed on the slider 40 , so as to realize the overall translation of the transporting hand 38 .

[0095] The first end of the rotating arm 47 is hinged on the swing arm base plate 45; the first end of the auxiliary arm 48 is hinged on the swing arm base plate 45 and is arranged adjacent to the first end of the rotating arm 47. The line connecting the two hinge points is defined as the first line, and the first line has an angle with the horizontal plane.

[0096] The second end of the auxiliary arm 48 is hinged to the first end of the balance arm 49, and the second end of the balance arm 49 is hinged to the second end of the rotating arm 47. The line connecting the two hinge points is defined as the second line, and the second line is parallel to the first line.

[0097] The connecting end of the horizontal fixing seat 50 is rotated to pass through the second end of the rotating arm 47 and is fixedly connected to the second end of the balancing arm 49; the horizontal fixing seat 50 is fixedly provided with the horizontal transfer platform 42 for positioning the cut bus bar 1, and the platform surface of the horizontal transfer platform 42 is parallel to the horizontal plane.

[0098] The horizontal transfer platform 42 is directly driven to rise and fall by the transporting hand 38 , and is indirectly translated by the sliding of the transporting hand 38 on the guide rail 43 .

[0099] In order to ensure the stability of the transport bus 1, the platform surface of the horizontal transfer platform 42 needs to always be parallel to the horizontal plane, so the first connecting line, the rotating arm 47, the auxiliary arm 48, and the balance arm 49 (the second connecting line) are designed as a parallelogram. Therefore, when the rotating drive mechanism 46 drives the rotating arm 47 to rotate, the first angle between the first connecting line and the horizontal plane can remain unchanged, and the second angle between the second connecting line and the horizontal plane also remains unchanged (and is the same as the first angle). Therefore, the parallel state of the platform surface of the horizontal transfer platform 42 fixed relative to the balance arm 49 and the horizontal plane also remains unchanged.

[0100] Preferably, a plurality of groups of second clamping jaw cylinders 41 for clamping the cut busbar 1 are arranged at intervals along the length direction on the platform surface of the horizontal transfer platform 42. Specifically, the second clamping jaw cylinder 41 can drive the second clamping jaw 44 to clamp and position the busbar 1.

[0101] Preferably, the handling hands 38 are provided with three pairs, and the three pairs of handling hands 38 are arranged at intervals along the length direction of the guide rail 43; wherein, the horizontal transfer platform 42 in the two pairs of handling hands 38 on both sides is used for clamping and positioning the busbar 1 that has only been cut; and the horizontal transfer platform 42 in the middle pair of handling hands 38 is used for clamping and positioning the busbar 1 that has been cut and bent.
