[0002] Before laser welding the motor controller power module and the overlapping copper busbar, the power module must be placed in the positioning tray first, and then the overlapping copper busbar is installed. During installation, one end of the overlapping copper busbar is placed on the copper busbar of the power module and the other end is placed on the tray.

[0003] After installation, the pallet moves from the manual installation station to the welding station via an automatic roller conveyor.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference below Figure 1-Figure 3 The load-bearing device 100 according to the embodiment of the utility model is described. The load-bearing device 100 can realize the fixed installation of the overlapping copper busbar 4, prevent the overlapping copper busbar 4 from being dislocated and offset, thereby realizing effective welding, reducing the welding scrap rate, avoiding material waste, and reducing costs.

[0031] like Figure 1-Figure 3 As shown, the carrying device 100 according to the embodiment of the utility model includes: a carrying station 1 and a positioning tray 2.

[0032] The carrying station 1 is provided with a pressing member 11 , and the positioning tray 2 is movably installed on the carrying station 1 . The positioning tray 2 is used to carry the power module 3 , and the positioning tray 2 is provided with a movable pressing structure 21 .

[0033] Specifically, the carrying station 1 is used to install and support the positioning tray 2 and other components. The power module 3 is installed on the positioning tray 2. The positioning tray 2 can move relative to the carrying station 1 to achieve the installation and fixation of the overlapping copper busbar 4. That is to say, after the power module 3 is placed on the positioning tray 2, it can move relative to the carrying station 1 together with the positioning tray 2 to achieve the placement of the overlapping copper busbar 4 on the positioning tray 2 and overlap the power module 3, which is beneficial to the next step of welding the supporting power module 3 and the overlapping copper busbar 4. Among them, a pressing piece 11 is provided on the carrying station 1. The pressing piece 11 can selectively press against the positioning tray 2 when the positioning tray 2 moves to achieve the installation and fixation of the overlapping copper busbar 4.

[0034] In actual design, the positioning tray 2 can be constructed as a rectangular plate structure, or other shape structures that are compatible with the shapes of the power module 3 and the overlapping copper busbar 4, and a limiting portion is set on the positioning tray 2 to limit and fix the power module 3, thereby improving the installation stability of the power module 3 and preventing the power module 3 from being misplaced and moving, affecting the overlap with the overlapping copper busbar 4, and then affecting the welding of the two, resulting in welding scrap.

[0035] Among them, when the positioning tray 2 moves along the first direction relative to the carrying station 1, the pressing member 11 is suitable for pushing the clamping structure 21 to switch to a loosened state for placing the overlapping copper busbar 4. After the positioning tray 2 moves along the second direction relative to the carrying station 1, the clamping structure 21 switches to a clamping state for clamping the overlapping copper busbar 4. The first direction is opposite to the second direction.

[0036] That is to say, the first direction and the second direction can be two opposite directions such as the up-down direction and the left-right direction. When the overlapping copper busbar 4 is actually installed, the carrying station 1 is fixed, and the positioning tray 2 moves relative to the carrying station 1 along the first direction. During the movement, the clamping structure 21 gradually approaches the pressing member 11, and moves until the pressing member 11 contacts and presses the clamping structure 21. At this time, the clamping structure 21 is in a loose state, that is, the clamping structure 21 is spaced a certain distance relative to the positioning tray 2, forming an installation space for installing the overlapping copper busbar 4, so that the overlapping copper busbar 4 It can be placed on the positioning tray 2 at the overlapping position corresponding to the power module 3 to complete the installation of the overlapping copper busbar 4. Then the positioning tray 2 moves along the second direction relative to the carrying station 1. During the movement, the clamping structure 21 gradually moves away from the pressing piece 11 and gradually approaches the positioning tray 2, moving until the clamping structure 21 presses on the overlapping copper busbar 4, pressing the overlapping copper busbar 4 on the positioning tray 2. At this time, the clamping structure 21 is in a clamping state, and the overlapping copper busbar 4 cannot move, thereby effectively fixing the overlapping copper busbar 4 on the carrying device 100.

[0037] In this way, a fixed overlap between the overlapping copper busbar 4 and the power module 3 is achieved, and the overlapping copper busbar 4 is tightly pressed against the positioning tray 2 and cannot be relatively misaligned with the power module 3, which is beneficial to the next welding process, and the carrying device 100 is convenient for placing the power module 3 and the overlapping copper busbar 4, and will not interfere with the manual placement of the module and the overlapping copper busbar 4. After the installation of the overlapping copper busbar 4 is completed, when the carrying device 100 is moved to the welding station for welding, the clamping structure 21 can always be tightly pressed against the overlapping copper busbar 4 during the movement, so that the overlapping copper busbar 4 will not be misaligned, and will not interfere with the automatic clamping tooling of laser welding during welding, and will not block the laser, so that effective welding can be performed, the utilization rate of materials is improved, material waste is avoided, and costs are greatly reduced. At the same time, after the welding is completed, the carrying device 100 will not interfere with the automatic grasping of the power module 3 and the overlapping copper busbar 4 by the transplanting mechanism.

[0038] According to the carrying device 100 of the embodiment of the utility model, by providing a pressing member 11 and a clamping structure 21, the pressing member 11 and the clamping structure 21 are selectively pressed, so that the clamping structure 21 can be in a loose state or a clamped state when the positioning tray 2 moves relative to the carrying station 1, and the overlapping copper busbar 4 is pressed between the clamping structure 21 and the positioning tray 2, thereby achieving fixed installation of the overlapping copper busbar 4, preventing the overlapping copper busbar 4 from being misaligned and offset, achieving effective welding, reducing the welding scrap rate, avoiding material waste, and reducing costs.

[0039] In some embodiments, the pressing structure 21 includes an adapter plate 211 , which is flippably mounted on the positioning tray 2 , and one end of the adapter plate 211 is directly opposite to the pressing member 11 along the moving direction of the positioning tray 2 .

[0040] That is, the adapter plate 211 can be turned over relative to the positioning tray 2 and selectively pressed against the pressing member 11 to achieve the pressing and fixing of the overlapping copper bar 4 on the positioning tray 2. Figure 1 and Figure 2 As shown, the adapter plate 211 is arranged on the installation tray, and the outer end of the adapter plate 211 is opposite to the pressing piece 11 along the movement direction of the positioning tray, and the pressing piece 11 is located in the first direction relative to the adapter plate 211. Therefore, the adapter plate 211 can be flipped so that during the movement of the positioning tray 2, the adapter plate 211 can press and contact or leave the pressing piece 11 to achieve the installation and fixation of the overlapping copper busbar 4.

[0041] When the positioning tray 2 moves along the first direction, the pressing member 11 presses against one end of the adapter plate 211 to switch the other end of the adapter plate 211 to a loosened state, and when the positioning tray 2 moves along the second direction, the pressing member 11 has no pressure on one end of the adapter plate 211 and switches the other end of the adapter plate 211 to a tightened state.

[0042] Specifically, in practice, Figure 1 As shown, when the positioning tray 2 moves along the first direction, the pressing member 11 presses against the outer end of the adapter plate 211 to cause the inner end of the adapter plate 211 to flip upward and switch to a loosened state, that is, the inner end of the adapter plate 211 leaves the surface of the positioning tray 2 and is separated from the positioning tray 2 by a certain distance, thereby avoiding the installation space of the overlapping copper busbar 4 above the positioning tray 2, which is conducive to placing the overlapping copper busbar 4 on the positioning tray 2.

[0043] Similarly, when the positioning tray 2 moves along the second direction, the outer end of the adapter plate 211 leaves the pressing piece 11 and flips upward, and no longer presses against the pressing piece 11, and the inner end of the adapter plate 211 flips downward and switches to a clamped state, that is, the inner end of the adapter plate 211 is close to the surface of the positioning tray 2 and tightly presses against the overlapping copper bus 4 on the positioning tray 2, pressing the overlapping copper bus 4 between the adapter plate 211 and the positioning tray 2, and cannot move.

[0044] In some embodiments, the positioning tray 2 further includes a movable rod 22 extending along the first direction, a middle portion of the adapter plate 211 is sleeved outside the movable rod 22 , and the adapter plate 211 is flippable relative to the movable rod 22 .

[0045] Specifically, Figure 1 As shown, the positioning tray 2 includes a movable rod 22, and the movable rod 22 extends along a first direction. Figure 2 As shown, a through hole may be provided at the middle position of the adapter plate 211 so that the middle portion of the adapter plate 211 can be sleeved outside the movable rod 22. The movable rod 22 supports the adapter plate 211, so that the two ends of the adapter plate 211 can be flipped relative to the movable rod 22, and the flipping direction is the same as the movement direction of the positioning tray 2, which is beneficial to tighten the overlapping copper busbar 4.

[0046] In some embodiments, the adapter plate 211 is movable along the length direction of the movable rod 22, and an elastic member 221 is provided on the outer sleeve of the movable rod 22. The elastic member 221 elastically presses against the adapter plate 211, and the elastic member 221 and the pressing member 11 are respectively located on both sides of the adapter plate 211. That is to say, the adapter plate 211 can be flipped by the elastic expansion and contraction of the elastic member 221, elastically pressed against the pressing member 11, or leave the pressing member 11, thereby realizing the installation of the overlapping copper bus 4.

[0047] Specifically, in practice, Figure 2As shown, the length direction of the movable rod 22 is consistent with the movement direction of the positioning tray 2. The movable rod 22 is installed on the positioning tray 2 and can move along the first direction or the second direction with the positioning tray 2. The adapter plate 211 moves along the length direction of the movable rod 22, that is, along the first direction or the second direction. The size of the elastic member 221 is adapted to the size of the movable rod 22, so that the elastic member 221 can be sleeved outside the movable rod 22 and expand and contract along the length direction of the movable rod 22 to generate an elastic force, wherein one end of the elastic member 221 is elastically pressed against the positioning tray 2, and the adapter plate 211 is installed above the elastic member 221, so that the other end of the elastic member 221 can be elastically pressed against the adapter plate 211, so that the elastic member 221 is elastically pressed between the adapter plate 211 and the positioning tray 2, and the elastic force of the elastic member 221 is used to realize the movable flipping of the adapter plate 211 on the movable rod 22.

[0048] Furthermore, the elastic member 221 and the pressing member 11 are respectively located on both sides of the adapter plate 211, so that when the actual positioning tray 2 moves along the first direction, the adapter plate 211 can move relative to the movable rod 22 along the second direction, and the elastic member 221 is compressed and deformed to generate elastic force, and at the same time, the outer end of the adapter plate 211 presses against the pressing member 11, and under the action of the elastic force, the inner end of the adapter plate 211 flips upward and moves away from the positioning tray 2, avoiding the installation space of the overlapping copper bar 4, and the overlapping copper bar 4 can be placed on the positioning tray 2. Similarly, when the actual positioning tray 2 moves along the second direction, the adapter plate 211 moves relative to the movable rod 22 along the first direction under the action of the elastic force, and the elastic member 221 gradually stretches to restore the initial state, and at the same time, the outer end of the adapter plate 211 leaves the pressing member 11, and there is no pressing against the pressing member 11, and the inner end of the adapter plate 211 presses against the overlapping copper bar 4, so that the overlapping copper bar 4 cannot be offset.

[0049] In actual design, the elastic member 221 can be configured as an elastically deformable component such as a spring.

[0050] In some embodiments, the positioning tray 2 is provided with a mounting bracket 23, one end of the movable rod 22 is connected to the mounting bracket 23, and the other end of the movable rod 22 is provided with a limiting boss 222 for limiting the adapter plate 211, and the elastic member 221 is pressed between the adapter plate 211 and the mounting bracket 23.

[0051] Specifically, Figure 2 As shown, the positioning tray 2 is provided with a mounting bracket 23, one end of the movable rod 22 is connected to the mounting bracket 23, that is, the movable rod 22 can be installed on the positioning tray 2 through the mounting bracket 23, and the other end of the movable rod 22 is provided with a limiting boss 222 which is larger than the radial dimension of the movable rod 22 and the dimension of the through hole in the middle of the adapter plate 211, so that the limiting boss 222 can limit the adapter plate 211 to prevent the adapter plate 211 from slipping off the movable rod 22 during the activity.

[0052] In some embodiments, the pressing member 11 is constructed as a bearing, the inner ring of the bearing is relatively fixed to the bearing station 1 , and the outer ring of the bearing is rolling pressed against one end of the adapter plate 211 .

[0053] Specifically, in actual design, a protruding shaft may be provided on the bracket of the carrying station 1, the inner ring of the bearing is sleeved on the shaft, and the outer ring of the bearing is sleeved outside the inner ring of the bearing. When the clamping structure 21 is in a loosened state, the outer ring of the bearing rolls and presses against one end of the adapter plate 211, that is, the outer ring of the bearing can roll relative to the adapter plate 211. Such a setting can reduce the friction between the pressing member 11 and the adapter, so that the pressing member 11 and the adapter are pressed more smoothly and reliably, thereby increasing the service life of the adapter, thereby improving the reliability and stability of the carrying device 100.

[0054] In some embodiments, the clamping structure 21 also includes a connecting rod 212 and a clamping block 213. The other end of the adapter plate 211 is connected to the connecting rod 212, and the connecting rod 212 is connected to the clamping block 213. The other end of the adapter plate 211 is suitable for driving the connecting rod 212 to rotate so that the clamping block 213 can switch between a loose state and a clamping state.

[0055] Specifically, Figure 1 As shown, the clamping structure 21 also includes a connecting rod 212 and a pressing block 213. The pressing block 213 is located above the overlapping copper bus 4 and is used to press the overlapping copper bus 4. The inner end of the adapter plate 211 is connected to the connecting rod 212, and the connecting rod 212 is connected to the pressing block 213. Therefore, when the adapter plate 211 is flipped, it can drive the connecting rod 212 to rotate together. The rotation of the connecting rod 212 can drive the pressing block 213 to move relative to the positioning tray 2, that is, the pressing block 213 moves away from or close to the positioning tray 2, and switches between a loose state and a clamping state. When the positioning tray 2 moves along the second direction, the connecting rod 212 and the pressing block 213 can be under the action of their gravity and the elastic force of the elastic member 221, so that when the pressing block 213 is pressed on the overlapping copper bus 4, the overlapping copper bus 4 is pressed and fixed between the pressing block 213 and the positioning tray 2 and cannot move.

[0056] It can be understood that the shape and position of the pressing block 213 can be flexibly changed following the shape and position of the overlapping copper busbar 4, and is not limited to what is described in this embodiment and shown in the drawings.

[0057] In some embodiments, there are multiple adapter plates 211, that is, the number of adapter plates 211 can be set to two, three, four or even more, and the multiple adapter plates 211 are all connected to the same connecting rod 212, that is, multiple adapter plates 211 are connected to one connecting rod 212, and the multiple adapter plates 211 move simultaneously to drive the connecting rod 212 to rotate, which can improve the stability and reliability of the rotation of the connecting rod 212.

[0058] And / or, the connecting rod 212 is connected to multiple pressing blocks 213, and the multiple pressing blocks 213 correspond to the multiple overlapping copper bars 4 one by one, that is, two, three, four or even more pressing blocks 213 can be connected to one connecting rod 212, and the connecting rod 212 rotates to simultaneously drive the multiple pressing blocks 213 to move, so that the multiple overlapping copper bars 4 can be stably pressed on the installation tray to prevent the multiple overlapping copper bars 4 from shifting.

[0059] like Figure 1 As shown, a plurality of adapter plates 211 and a plurality of pressing blocks 213 are connected to the connecting rod 212, and the plurality of adapter plates 211 and the plurality of pressing blocks 213 are respectively located on both sides of the connecting rod 212. When the plurality of adapter plates 211 flip, they drive the connecting rod 212 to rotate, and the rotation of the connecting rod 212 drives the plurality of pressing blocks 213 to be in a loosened state or a compressed state, so as to install and fix the plurality of overlapping copper bars 4, so that the plurality of overlapping copper bars 4 can compress the plurality of overlapping copper bars 4 respectively and correspondingly.

[0060] It can be understood that the more the number of adapter plates 211 is set, the more conducive it is to drive the connecting rod 212 and the pressure block 213 to move. The number of adapter plates 211 can be flexibly set according to actual needs and space size. The number of pressure blocks 213 can be flexibly set according to the number of overlapping copper bars 4 to improve the stability of the overlapping copper bars 4.

[0061] In some embodiments, there are two groups of pressing structures 21 , and the two groups of pressing structures 21 are respectively located at two ends of the positioning tray 2 .

[0062] Specifically, Figure 1 As shown, two sets of clamping structures 21 are provided on the positioning tray 2, which are respectively located on both sides of the positioning tray 2, so that the overlapping copper bars 4 on both sides of the power module 3 can be fixed, so that the power module 3 can be overlapped with the overlapping copper bars 4 to prevent the power module 3 from being misaligned with the overlapping copper bars 4.

[0063] In some embodiments, the first direction is vertically upward, and the second direction is vertically downward.

[0064] That is to say, when the positioning tray 2 moves vertically upward relative to the carrying station 1, the pressing piece 11 contacts and presses the adapter plate 211 to push the clamping structure 21 to switch to a loosened state to place the overlapping copper busbar 4; when the positioning tray 2 moves vertically downward relative to the carrying station 1, there is no pressure between the pressing piece 11 and the adapter plate 211, and the clamping structure 21 switches to a clamping state to clamp the overlapping copper busbar 4.

[0065] Thus, by moving the positioning tray 2 back and forth vertically upward or vertically downward, the overlapping copper busbars 4 can be pressed and fixed.

[0066] In actual design, the positioning tray 2 can achieve vertical upward and vertical downward movement through the lifting and lowering of the line body lifting cylinder.
