In order to solve the technical problems of the prior shaping mechanism, the utility model provides a bus bar shaping mechanism which is used for shaping two bus bars on a photovoltaic module, wherein the two bus bars are a first bus bar and a second bus bar respectively.

As shown in fig. 1 to 8, the bus bar shaping mechanism provided in the embodiment of the present utility model includes a lifting module 1, a mounting bracket 2, a supporting component 3, a first shaping component 4 and a second shaping component 5, wherein:

The lifting module 1 is also used for driving the mounting bracket 2 to lift so as to drive the supporting component 3, the first shaping component 4 and the second shaping component 5 to straighten the two bus bars upwards.

The bus bar shaping mechanism of the embodiment of the utility model has the following working processes:

the lifting module 1 drives the mounting bracket 2 to descend toward the two bus bars such that the support member 3 is inserted between the first bus bar 100 and the second bus bar 200, and the first shaping member 4 and the second shaping member 5 are pressed against the photovoltaic module 300.

Next, the first shaping member 4 is moved from the first side toward the support member 3, the first shaping member 4 presses the first bus bar 100 onto the first support surface 321 of the support member 3 via the first shaping surface 44, and the first protruding portion 45 abuts against the root portion of the first bus bar 100. At the same time, the second shaping assembly 5 moves from the second side towards the support assembly 3, the second shaping assembly 5 presses the second bus bar 200 via the second shaping surface 54 onto the second support surface 331 of the support assembly 3, and the second protrusion 55 abuts against the root of the second bus bar 200.

Then, the lifting module 1 drives the mounting bracket 2 to lift away from the two bus bars, the first shaping assembly 4, the second shaping assembly 5 and the supporting assembly 3 cooperate to straighten the two bus bars upwards, and at the same time, the first protruding part 45 and the second protruding part 55 straighten the first bus bar 100 and the second bus bar 200 twice, and in the straightening process of the twice, the first protruding part 45 and the second protruding part 55 can respectively open wrinkles on the first bus bar 200 and the second bus bar 200, so that straightening effects on the first bus bar 100 and the second bus bar 200 are ensured.

With continued reference to fig. 1, the bus bar shaping mechanism according to the embodiment of the present utility model further includes a first mounting plate 6 and an elastic connection member 7, wherein: the first mounting plate 6 is mounted on the driving end of the lifting module 1, the upper end of the elastic connecting piece 7 is connected to the first mounting plate 6, and the mounting bracket 2 is connected to the lower end of the elastic connecting piece 7. When the lifting module 1 drives the first mounting plate 2 to descend and the mounting bracket 2 is driven to synchronously descend to the target position, the supporting component 3 is inserted between the first bus bar and the second bus bar, the elastic connecting piece 7 is compressed under pressure, and the first shaping component 4 and the second shaping component 5 are elastically pressed against the photovoltaic component.

The first shaping assembly 4 and the second shaping assembly 5 are elastically pressed against the photovoltaic assembly, so that the risk of pressure loss of the first shaping assembly 4 and the second shaping assembly 5 to the photovoltaic assembly can be reduced, and the first shaping assembly 4 and the second shaping assembly 5 can be ensured to be capable of tightly adhering to the photovoltaic assembly and sliding towards the supporting assembly 3, and corresponding bus bars are finally pressed onto the supporting assembly 3.

In the process of driving the mounting bracket 2 to descend by the lifting module 1, the elastic connecting piece 7 is compressed. When the elastic connection member 7 is compressed to a predetermined compression amount, the sensing piece 9 triggers the photoelectric sensor 8, the photoelectric sensor 11 generates a stop trigger signal, and the lifting module 1 stops driving the first mounting plate 6. In this way, the first shaping component 4 and the second shaping component 5 can be ensured to be elastically pressed against the photovoltaic component with a preset large force, so that the pressure of the first shaping component 4 and the second shaping component 5 to the photovoltaic component is prevented from being too large, and the photovoltaic component is prevented from being damaged.

Of course, the mounting positions of the photoelectric sensor 8 and the sensing piece 9 may be exchanged, that is, the photoelectric sensor 8 may be mounted on the mounting bracket 2 and the sensing piece 9 may be mounted on the first mounting plate 6.

As shown in fig. 1 and 2, to facilitate the mounting layout of the first shaping assembly 4, the second shaping assembly 5 and the support assembly 3, the mounting bracket 2 optionally includes a second mounting plate 21, a first riser 22 and a second riser 23, wherein: the second mounting plate 21 is connected to the driving end of the lifting module 1. The upper ends of the first vertical plate 22 and the second vertical plate 23 are fixedly connected to the second mounting plate 21, the first shaping assembly 4 is arranged at the lower end of the first vertical plate 22, the second shaping assembly 5 is arranged at the lower end of the second vertical plate 23, and the supporting assembly 3 is arranged on the second mounting plate 21 and positioned between the first vertical plate 22 and the second vertical plate 23.

Alternatively, as shown in fig. 2 and 3, the first shaping assembly 4 includes a first shaping block driving member 41 and a first shaping block 42, where the first shaping block driving member 41 is mounted on the mounting bracket 2, the first shaping block 42 is connected to a driving end of the first shaping block driving member 41, a first shaping projection 43 is disposed on the first shaping block 42, an end surface of the first shaping projection 43 facing the support assembly 3 is a first shaping surface 44, and a lower end edge of the first shaping projection 43 protrudes outwards from the first shaping surface to form a first protruding portion 45. The first shaping block driving member 41 is configured to drive the first shaping block 42 to move toward the support assembly 3, so as to drive the first shaping surface 44 to press the first bus bar 100 onto the first support surface 321 of the support assembly 3, and drive the first protrusion 45 to abut against the root of the first bus bar 100.

As shown in fig. 2 and 4, the second shaping assembly 5 includes a second shaping block driving member 51 and a second shaping block 52, where the second shaping block driving member 51 is mounted on the mounting bracket 2, the second shaping block 52 is connected to a driving end of the second shaping block driving member 51, a second shaping projection 53 is disposed on the second shaping block 52, an end surface of the second shaping projection 53 facing the support assembly 3 is a second shaping surface 54, and a lower end edge of the second shaping projection 53 protrudes outwards from the second shaping surface 54 to form a second protruding portion 55. The second shaping block driving member 51 is configured to drive the second shaping block 52 to move toward the support assembly 3, so as to drive the second shaping surface 54 to press the second bus bar 200 onto the second support surface 331 of the support assembly 3, and drive the second protrusion 55 to abut against the root of the second bus bar 200.

After the first shaping block 42 and the second shaping block 52 press the first bus bar and the second bus bar onto the first supporting surface 321 and the second supporting surface 331 of the supporting component 3, when the lifting module 1 drives the mounting bracket 2 to lift away from the two bus bars, the first shaping surface 44 of the first shaping component 4 and the second shaping surface 54 of the second shaping component 5 cooperate with the first supporting surface 321 and the second supporting surface 331 of the supporting component to straighten the two bus bars upwards. At the same time, the first and second protrusions 45 and 55 perform secondary straightening of the first and second bus bars.

In general, in the process of tearing off the high-temperature fabric, the two bus bars are lifted to make the bus bars in an inclined state, and at this time, with the bus bar shaping mechanism in the above embodiment, the first shaping protrusion 43 and the second shaping protrusion 53 can push and press the two bus bars onto the first supporting surface 321 and the second supporting surface 331 respectively in the process of moving towards the bus bars.

However, there are special cases where the bus bar may not be completely lifted after the high temperature cloth is torn off, i.e., the bus bar is still attached to the photovoltaic module. In this case, the first shaping protrusion 43 and the second shaping protrusion 53 will not smoothly push up the bus bar in the process of moving toward the bus bar, and straightening of the bus bar will not be completed finally.

In order to solve this problem, optionally, the bus bar shaping mechanism in the embodiment of the present utility model further includes a traversing module, and the lifting module 1 is connected to a driving end of the traversing module. As shown in fig. 3 and 4, the first shaping block 42 is further provided with a first shovel 46, and the first shovel 46 and the first shaping bump 43 are arranged side by side along a first horizontal direction (such as an X-axis direction in the drawing). The second shaping block 52 is further provided with a second shovel 56, where the second shovel 56 and the second shaping bump 53 are arranged side by side along the first horizontal direction (such as the X-axis direction in the figure), and the second shovel 56 is opposite to the first shovel 46.

The bus bar shaping mechanism works as follows:

the traversing module drives the mounting bracket 2 to translate in a first horizontal direction to a first position such that the first blade 46 and the second blade 56 move over two bus bars.

The lifting module 1 drives the mounting bracket 2 to descend so that the first shaping block 42 and the second shaping block 52 descend and finally press against the photovoltaic module. Then, the first shaping block driving piece 41 drives the first shaping block 42 to move towards the supporting component 3, so as to drive the first shovel 46 to be inserted between the first bus bar and the photovoltaic component; in synchronization, the second shaping block driving member 51 drives the second shaping block 52 to move towards the supporting component 3, so as to drive the second shovel 56 to be inserted between the second bus bar and the photovoltaic component.

The lifting module 1 then drives the first shaping block 42 and the second shaping block 52 to lift away from the photovoltaic module, and drives the first shovel 46 and the second shovel 56 to shovel the first bus bar and the second bus bar from the photovoltaic module, respectively.

Next, the traversing module drives the mounting bracket 2 to translate to the second position along the first horizontal direction, so that the first shaping bump 43 and the second shaping bump 53 move over the two bus bars.

The lifting module 1 drives the mounting bracket 2 to descend so that the support member 3 is inserted between the two scooped bus bars, and so that the first shaping block 42 and the second shaping block 52 are pressed against the photovoltaic member. Next, the first shaping block driving member 41 drives the first shaping block 42 to move towards the supporting component 3, so as to drive the first shaping protrusion 43 to press the first bus bar onto the first supporting surface of the supporting component 3, and the first protrusion 45 abuts against the root of the first bus bar; in synchronization, the second shaping block driving member 51 drives the second shaping block 52 to move towards the supporting component 3, so as to drive the second shaping protrusion 53 to press the second bus bar onto the second supporting surface of the supporting component 3, and the second protrusion 55 abuts against the root of the second bus bar.

Then, the lifting module 1 drives the mounting bracket 2 to lift away from the two bus bars, the first shaping block 42 and the second shaping block 52 are matched with the supporting component 3 to straighten the two bus bars upwards, and at the same time, the first protruding part 45 and the second protruding part 55 perform secondary straightening on the first bus bar and the second bus bar.

It can be seen that by providing the first and second spade pieces 46, 56 on the first and second shaping blocks 42, 52, respectively, the first and second shaping blocks 42, 52 are enabled to scoop the first and second bus bars from the photovoltaic module, thereby ensuring that the first and second shaping blocks 42, 52 are capable of smoothly compressing the first and second bus bars onto the first and second support surfaces of the support module 3.

Alternatively, as shown in fig. 3, 4, and 7, the first support surface 321 and the second support surface 331 are convex arc-shaped support surfaces; the first shaping surface 44 and the second shaping surface 54 are concave arcuate shaping surfaces that mate with the arcuate support surfaces; the shaped ends of the first and second bosses 45, 55 (i.e., near the front face of the bus bar) are concave arcuate surfaces.

This arrangement ensures that the first and second shaping surfaces 44, 54 are able to press the first and second bus bars more firmly against the first and second support surfaces 321, 331 of the support assembly 3. The first and second protruding portions 45 and 55 can stably abut against the root portions of the first and second bus bars, and the shaping effect on the bus bars is finally improved.

As shown in fig. 5 to 8, the support assembly 3 includes a jaw cylinder 31, a first support block 32, and a second support block 33, wherein: the clamping jaw cylinder 31 is mounted on the mounting bracket 2, and the first support block 32 and the second support block 33 are respectively connected to the first driving end and the second driving end of the clamping jaw cylinder 31.

The inner side surface of the first support block 32 and the inner side surface of the second support block 33 are both flat, and the inner side surface of the first support block 32 is close to the inner side surface of the second support block 33.

The outer side surface of the first support block 32 includes a first support surface 321, a first inclined surface 322 and a first escape surface 323 connected in sequence, and the first support surface 321 is adjacent to the first driving end of the jaw cylinder 31; the distance between the first support surface 321 and the inner side surface of the first support block 32 is greater than the distance between the first avoidance surface 323 and the inner side surface of the first support block 32. That is, the first support block 32 has a greater thickness at the location of the first support surface 321 than at the location of the first relief surface 323.

The outer side surface of the second support block 33 includes a second support surface 331, a second inclined surface 332, and a second avoidance surface 333 connected in sequence, and the second support surface 331 is adjacent to the second driving end of the jaw cylinder 31; the distance between the second support surface 331 and the inner side surface of the second support block 33 is greater than the distance between the second avoidance surface and the inner side surface of the second support block 33. That is, the second support block 33 has a greater thickness at the location of its second support surface 331 than at the location of its second relief surface 333.

The clamping jaw cylinder 31 is used for driving the first supporting block 32 and the second supporting block 33 to relatively move so as to realize the switching of the supporting assembly 3 between the avoidance state and the supporting state. As shown in fig. 5 and 6, when the support assembly 3 is switched to the avoidance state, the projections of the first avoidance surface 323 and the second avoidance surface 333 on the vertical plane parallel to the inner side surface of the first support block 32 and the inner side surface of the second support block 33 at least partially overlap, and the first support surface 321 and the second support surface 331 are staggered.

As shown in fig. 7 and 8, when the support assembly 3 is switched to the support state, the first avoidance surface 323 and the second avoidance surface 333 are staggered, and the projections of the first support surface 321 and the second support surface 331 on the vertical plane are at least partially overlapped.

Before shaping the bus bar is performed, as shown in fig. 5 to 6, the jaw cylinder 31 drives the first support block 32 and the second support block 33 to move toward both sides relatively, so that the support assembly 3 is switched to the avoidance state. At this time, the entire thickness of the middle portion of the support member 3 is a thin first thickness.

Thus, when the lifting module 1 drives the mounting bracket 2 to descend, the middle portion of the support assembly 3 with a thinner thickness can be smoothly inserted between the first bus bar 100 and the second bus bar 200, so that the first bus bar 100 and the second bus bar 200 are prevented from being excessively small in distance due to deformation and the like, and the support assembly 3 cannot be smoothly inserted between the first bus bar and the second bus bar.

When the lifting module 1 is driven in place, the middle portion of the support assembly 3 is completely inserted into the first bus bar 100 and the second bus bar 200, as shown in fig. 7 to 8, the clamping jaw cylinder 31 drives the first support block 32 and the second support block 33 to relatively move towards the middle, so that the support assembly 3 is switched to a supporting state. At this time, the entire thickness of the middle portion of the support member 3 is a thicker second thickness, so that the first and second support surfaces 321 and 331 of the support member 3 can contact the first and second bus bars 100 and 200, respectively, to achieve support of the first and second bus bars 100 and 200.

As shown in fig. 5 and 8, the support assembly 3 further comprises a first stopper 34 and a second stopper 35, wherein: the first stopper 34 is mounted on the first driving end of the jaw cylinder 31, and the first support block 32 is connected to the first stopper 34. The second stopper 35 is mounted on the second driving end of the jaw cylinder 31, and the second support block 33 is connected to the second stopper 35. The side surface of the first limiting block 34 opposite to the second limiting block 35 is a first poking front surface, and the side surface of the second limiting block 35 opposite to the first limiting block 34 is a second poking front surface.

The jaw cylinder 31 drives the first support block 32 and the second support block 33 to move relatively, and in the process of switching the support assembly 3 to the support state, the first correcting surface and the second correcting surface correct two bus bars simultaneously from two sides of the bus bars in the width direction respectively, so that the bus bars with inclination in the width direction are corrected.

After the first stopper 34 and the second stopper 35 align the bus bars, the first shaping block driving member 41 may drive the first shaping protrusion 43 to move toward the first bus bar 100, so that the first shaping surface 44 presses the first bus bar 100 onto the first supporting surface 321, and the first protrusion 45 abuts against the root of the first bus bar 100; the second shaping block driver 51 may drive the second shaping protrusion 53 toward the second bus bar 200 such that the second shaping surface 54 presses the second bus bar 200 against the second support surface 331 while the second boss 55 abuts against the root of the second bus bar 200; next, the lifting module 1 drives the mounting bracket 2 to lift away from the two bus bars, and the first limiting block 34 and the second limiting block 35 limit the first bus bar 100 and the second bus bar 200 in the width direction in the lifting process, so that the bus bars are prevented from being skewed in the straightening process.

The utility model has been described above in sufficient detail with a certain degree of particularity. It will be appreciated by those of ordinary skill in the art that the descriptions of the embodiments are merely exemplary and that all changes that come within the true spirit and scope of the utility model are desired to be protected. The scope of the utility model is indicated by the appended claims rather than by the foregoing description of the embodiments.
