Description

Technical Field

[0001] This invention relates to the field of photovoltaic module manufacturing technology, and in particular to a tape cutting and placement device and a busbar string welding machine. Background Technology

[0002] When welding busbars onto photovoltaic modules, the busbars must first be placed on the module according to their welding positions. Then, tape is used to attach the busbars to the module, stabilizing them. Currently, tape cutting equipment is typically used. This equipment includes a tape reel, multiple winding rollers, and an automatic cutter. The tape on the reel is passed sequentially through the winding rollers, then manually pulled to the appropriate length, before being cut by the automatic cutter.

[0003] Because the current action of pulling the tape relies on manual labor, it is difficult to ensure that the length of the tape is within the appropriate range after each pull. This often results in the tape being too long or too short, which will affect the subsequent bonding effect. In addition, manually pulling the tape is time-consuming, laborious, and inefficient. Summary of the Invention

[0004] The first objective of this invention is to provide a tape cutting and placement mechanism to solve the technical problems of inconsistent tape cutting lengths, high manual labor load, and low work efficiency in the prior art.

The tape feeding tray is used to carry the strip-shaped tape; the tape pulling mechanism can pull the free end of the strip-shaped tape to a set position so that the tape cutting mechanism can cut the strip-shaped tape into tape segments of a set length; the tape picking mechanism can pick up the cut tape segments. The tape leveling mechanism is located between the tape supply tray and the tape cutting mechanism, and includes a leveling wheel. The leveling wheel is connected to the tape preparation support by floating up and down, and the tape led out from the tape supply tray is wound around the bottom of the leveling wheel. The tape cutting mechanism (4) includes a support base plate (41) and a blade (43). The support base plate (41) is mounted on the tape preparation bracket (1) and is used to support the tape. The tape end support assembly (9) includes a tape support piece (91), which is disposed between the support base plate (41) and the blade (43) and is used to support the free end of the tape. The tape support piece (91) retracts when the tape pulling mechanism (5) clamps the free end of the tape, and extends when the blade (43) cuts the tape.

[0006] Furthermore, the tape leveling mechanism also includes a leveling shaft, a leveling seat, a leveling guide rod, and a leveling block. The leveling wheel is mounted on the leveling shaft, the leveling seat is mounted on the tape preparation bracket, the leveling guide rod is mounted on the leveling seat, the leveling shaft is mounted on the leveling block, and the leveling block is slidably disposed on the leveling guide rod.

[0007] Furthermore, the leveling base is U-shaped and includes an upper horizontal plate, a lower horizontal plate, and a vertical plate disposed between the upper horizontal plate and the lower horizontal plate; the two ends of the leveling guide rod are respectively fixed to the upper horizontal plate and the lower horizontal plate; The tape leveling mechanism also includes a compression spring, the two ends of which abut against the upper horizontal plate and the leveling block, respectively.

[0008] Furthermore, the tape cutting mechanism is also equipped with a cutting drive unit on the tape preparation bracket, the blade is connected to the cutting drive unit in a transmission manner, and the cutting drive unit can drive the blade to move in a direction away from or close to the support base plate.

[0010] Furthermore, the mounting component is provided with a blade mounting groove, and one end of the blade is inserted into the blade mounting groove.

[0011] Furthermore, the mounting component is provided with a sliding hole, and the slider passes through the sliding hole; the two ends of the slider are respectively provided with the pressure head and the limiting plate.

[0012] Furthermore, it also includes a transfer mechanism, wherein the tape preparation bracket is connected to the transfer mechanism in a transmission manner, so that the transfer mechanism can drive the tape preparation bracket to move to a set position.

[0013] Furthermore, the tape segment picked up by the tape picking mechanism is used to place on the workpiece to be processed; the tape cutting and placing device also includes a tape pressing mechanism that is connected to the transfer mechanism in a transmission manner. The tape pressing mechanism includes a tape pressing head drive and a tape pressing head.

[0015] The beneficial effects of this invention are: This invention provides a tape cutting and placement device and a busbar stringing machine. The tape cutting and placement device includes a tape preparation support and a tape feeding tray, a tape leveling mechanism, a tape cutting mechanism, a tape pulling mechanism, and a tape picking mechanism mounted on the tape preparation support. The tape feeding tray carries a coiled tape. The tape pulling mechanism pulls the free end of the coiled tape to a set position so that the tape cutting mechanism cuts the coiled tape into tape segments of a set length. The tape picking mechanism picks up the cut tape segments. The tape leveling mechanism is located between the tape feeding tray and the tape cutting mechanism and includes a leveling wheel that is vertically connected to the tape preparation support. The tape drawn from the tape feeding tray is wound around the bottom of the leveling wheel. Under the influence of gravity, the leveling wheel tends to move downwards, thus tightening the tape and preventing it from twisting. When the tape pulling mechanism pulls the free end of the tape, the leveling wheel will move upwards appropriately due to the tension, avoiding damage or breakage of the tape caused by forcibly pulling it. After the tape is no longer pulled, the tape bends downwards under the pressure of the leveling wheel, so that the entire tape is no longer taut. The bent part of the tape is equivalent to leaving a portion for the next pull. Attached Figure Description

Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should be noted that in the description of this invention, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] It should be noted that in the description of this invention, the terms "connection" and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Example 1 Embodiment 1 of the present invention provides a tape cutting and placement device, referring to... Figure 1 and Figure 2 The device includes a tape preparation support 1, a tape feeding tray 2 mounted on the tape preparation support 1, a tape leveling mechanism 3, a tape cutting mechanism 4, a tape pulling mechanism 5, and a tape picking mechanism 6. Among them, the tape feeding tray 2 is used to carry the strip-shaped tape; the tape pulling mechanism 5 can pull the free end of the strip-shaped tape to a set position so that the tape cutting mechanism 4 can cut the strip-shaped tape into tape segments 100 of a set length; the tape picking mechanism 6 can pick up the cut tape segments 100. The tape leveling mechanism 3 is located between the tape feeding tray 2 and the tape cutting mechanism 4. It includes a leveling wheel 32, which is connected to the tape preparation support 1 by floating up and down. The tape led out from the tape feeding tray 2 is wound around the bottom of the leveling wheel 32.

[0023] Reference Figure 1 The tape leading from below the leveling wheel 32 is guided to the tape cutting mechanism 4. Under the influence of gravity, the leveling wheel 32 tends to move downward, thereby tightening the tape and preventing it from twisting. When the tape pulling mechanism 5 pulls the free end of the tape, the leveling wheel 32 will move upward appropriately under the action of tension to avoid forcibly pulling the tape and causing damage or breakage. After the tape is no longer pulled, the tape bends downward under the pressure of the leveling wheel 32, so that the entire tape is no longer taut. The bent part of the tape is equivalent to leaving a portion for the next pull.

[0024] In this embodiment, the tape leveling mechanism 3 further includes a first guide wheel and a second guide wheel. The first guide wheel and the second guide wheel are respectively disposed on opposite sides of the leveling wheel 32, and the first guide wheel, the leveling wheel 32, and the second guide wheel are arranged sequentially along the tape conveying direction. The tape led out from below the tape feed tray 2 is sequentially wound around the top of the first guide wheel, the bottom of the leveling wheel 32, and the top of the second guide wheel, and then guided to the tape cutting mechanism 4. The arrangement of multiple guide wheels can further prevent tape twisting and improve the tape cutting effect.

[0025] Reference Figure 2The tape leveling mechanism 3 further includes a leveling shaft 31, a leveling seat 33, a leveling guide rod 34, and a leveling block 35. The leveling wheel 32 is mounted on the leveling shaft 31, the leveling seat 33 is mounted on the tape preparation bracket 1, the leveling guide rod 34 is mounted on the leveling seat 33, and the leveling shaft 31 is mounted on the leveling block 35. The leveling block 35 is slidably mounted on the leveling guide rod 34. Specifically, the leveling seat 33 is U-shaped and includes an upper horizontal plate, a lower horizontal plate, and a vertical plate disposed between the upper and lower horizontal plates. The two ends of the leveling guide rod 34 are fixed to the upper and lower horizontal plates, respectively. Optionally, the leveling shaft 31 and the leveling wheel 32 are connected by bearings.

[0026] In this embodiment, the tape leveling mechanism 3 further includes a compression spring 36, with its two ends abutting against the upper horizontal plate and the leveling block 35, respectively. The compression spring 36 can apply a spring force to the leveling block 35 to move downwards. In other embodiments, the compression spring 36 may be omitted, and instead, a counterweight may be installed on the leveling block 35, or the weight of the leveling block 35 may be increased or decreased to apply appropriate tension to the tape. In this embodiment, there are two leveling guide rods 34, and the compression spring 36 is disposed between the two leveling guide rods 34. The upper horizontal plate and the leveling block 35 are respectively provided with slots, and the two ends of the compression spring 36 are respectively inserted into the slots on the upper horizontal plate and the leveling block 35.

[0027] Reference Figure 3 The tape cutting mechanism 4 includes: A support base plate 41 is mounted on the tape preparation bracket 1 and is used to support the tape. The cutting drive component 42 is mounted on the tape preparation bracket 1; The blade 43 is disposed between the tape pulling mechanism 5 and the support base plate 41, and is connected to the cutting drive component 42 for transmission. The cutting drive component 42 can drive the blade 43 to move in a direction away from or towards the support base plate 41. In this embodiment, the cutting drive component 42 is specifically a cylinder, and the blade 43 is mounted on the end of the piston rod of the cylinder.

[0028] Optionally, positioning bosses are provided on opposite sides of the support base plate 41, and a gap is formed between the positioning bosses on both sides for the tape to pass through.

[0029] Furthermore, the tape cutting mechanism 4 also includes a tape pressing assembly 49, which includes a pressing seat 491, a pressing slider 492, a pressing wheel 493, and a pressing spring 494. The pressing seat 491 is fixed to the tape preparation bracket 1. The pressing slider 492 is slidably connected to the pressing seat 491. The two ends of the pressing spring 494 abut against the pressing seat 491 and the pressing slider 492, respectively. The pressing wheel 493 is rotatably connected to the pressing slider 492 and is positioned above the supporting base plate 41. Under the combined action of gravity and the pressing spring 494, the pressing wheel 493 tends to move downwards, thereby clamping the tape between the pressing wheel 493 and the supporting base plate 41 to prevent the tape from moving during cutting. In this embodiment, the pressing seat 491 is U-shaped, and the supporting base plate 41 is fixed to the pressing seat 491.

[0030] Reference Figure 4 and Figure 5 The tape cutting mechanism 4 also includes a mounting component 44, a slider 45, a pressure head 46, and an elastic element 47. The mounting component 44 is connected to the cutting drive component 42. The blade 43 is fixed on the mounting component 44, the slider 45 is slidably disposed on the mounting component 44, the pressure head 46 is fixed to one end of the slider 45 near the support base plate 41, and the two ends of the elastic element 47 abut against the mounting component 44 and the pressure head 46, respectively. In this embodiment, the elastic element 47 is specifically a compression spring. The cutting drive component 42 has a first state of extending the blade 43 and a second state of retracting the blade 43. When the cutting drive component 42 is in the second state, the vertical distance between the pressure head 46 and the support base plate 41 is less than the vertical distance between the blade 43 and the support base plate 41. The tape can be clamped between the pressure head 46 and the support base plate 41. The working process of the tape cutting mechanism 4 is as follows: In the initial state, the cutting drive 42 is in the second state, and the tape on both sides of the blade 43 is fixed to the tape pulling mechanism 5 and the tape pressing assembly 49, respectively. The blade 43 and the pressing head 46 are both suspended above the tape. When cutting the tape, the cutting drive 42 drives the mounting part 44 to move downward, which in turn drives the blade 43 and the pressing head 46 to move downward. During the movement of the mounting part 44, the pressing head 46 first contacts the tape. Then, the mounting part 44 continues to move, compressing the elastic part 47, and the tape is clamped between the support base plate 41 and the pressing head 46. Then, the mounting part 44 drives the blade 43 to continue moving until the cutting drive 42 is in the first state, and the blade 43 cuts the tape into segments. Thus, one cutting process is completed.

[0031] A silicone foam block can be placed below the pressure head 46 to prevent tape from sticking to the pressure head 46.

[0032] In this embodiment, the tape cutting mechanism 4 and the tape picking mechanism 6 are respectively disposed on the upper and lower sides of the tape. The tape picking mechanism 6 includes a rotating component, and multiple suction heads are arranged circumferentially on the rotating component. The multiple suction heads are all connected to a vacuum generator. The rotating component can drive the suction heads to rotate, so that one of the suction heads is located directly below the tape and between the blade 43 and the tape pulling mechanism 5, thereby allowing the suction head to pick up the cut tape segments 100. Setting multiple suction heads can store multiple tape segments 100, improving work efficiency.

[0033] Reference Figure 5 The mounting component 44 is provided with a sliding hole, through which the slider 45 passes; a pressure head 46 and a limiting plate 48 are respectively provided at both ends of the slider 45. The limiting plate 48 can limit the downward movement limit of the slider 45.

[0034] Reference Figure 6 The mounting component 44 includes a blade mounting plate 441 and a pressure head mounting plate 442, which are connected by screws. The blade 43 is fixed on the blade mounting plate 441, and the pressure head 46 is mounted on the pressure head mounting plate 442. The mounting component 44 (specifically the blade mounting plate 441) is provided with a blade mounting groove 4411, and one end of the blade 43 is inserted into the blade mounting groove 4411 and fixed by screws.

[0035] Reference Figure 7 The tape cutting and placement mechanism also includes a tape end support assembly 9, which includes a tape support piece 91. The tape support piece 91 is positioned between the support base plate 41 and the blade 43 to support the free end of the tape. After the tape cutting mechanism 4 cuts the tape, the tape support piece 91 can support the free end of the tape, preventing it from bending downwards, thus facilitating the gripping of the tape pulling mechanism 5. The tape support piece 91 is linked and cooperates with both the pressure head mounting plate 442 and the tape pulling mechanism 5. Specifically, the tape support piece 91 retracts when the tape pulling mechanism 5 grips the free end of the tape, and extends when the pressure head mounting plate 442 descends and the blade 43 cuts the tape. Therefore, the tape support piece 91 does not obstruct the tape pulling mechanism 5 from gripping the tape, and it can promptly support the end of the tape after cutting. In actual installation, the support surface of the tape support piece 91 is slightly lower than the support surface of the support base plate 41.

[0036] Reference Figure 8The tape end support assembly 9 includes a first active block 92, a first driven block 93, and a driven block guide rail 96. The first active block 92 is fixed to the pressure head mounting plate 442 by screws. The first driven block 93 has a slot into which the tape support piece 91 is inserted and fixed by screws. The first driven block 93 is slidably connected to the driven block guide rail 96, which is fixed to the tape preparation bracket 1. The first active block 92 has a first inclined surface 921, and the first driven block 93 has a second inclined surface 931. The first and second inclined surfaces 921 cooperate to cause the pressure head mounting plate 442 to descend while simultaneously moving the tape support piece 91 towards the tape. Optionally, limit screws can be provided at both ends of the driven block guide rail 96 to prevent the first driven block 93 from dislodging.

[0037] Reference Figure 9 The tape-pulling mechanism 5 includes a gripper mounting base 51 and two grippers 52 mounted on the gripper mounting base 51. The two grippers 52 are hinged together and used to clamp or release the tape. Only the lower gripper is shown in the figure; the upper gripper is not shown for easier viewing.

[0038] The tape end support assembly 9 includes a second active block 94 and a second driven block 95; wherein, the second active block 94 is fixed to the gripper mounting base 51 by screws; the second driven block 95 is fixed to the first driven block 93 by screws; the second active block 94 is provided with a third inclined surface 941, and the second driven block 95 is provided with a fourth inclined surface 951. Through the cooperation of the third inclined surface 941 and the fourth inclined surface 951, the gripper mounting base 51 moves closer to the support base plate 41 while driving the tape support piece 91 to move away from the tape.

[0039] Reference Figure 10 The tape cutting and placement device also includes a transfer mechanism 7. The tape preparation bracket 1 is connected to the transfer mechanism 7 so that the transfer mechanism 7 can drive the tape preparation bracket 1 to a set position, thereby moving the cut tape segment 100 to the set position.

[0040] Specifically, the transfer mechanism 7 includes a mounting frame 71, a transfer support 72, an X-axis moving assembly 73, and a Z-axis moving assembly 75, wherein: The X-axis moving assembly 73 includes a conveyor belt 731, a drive motor, a drive wheel, and a driven wheel. The drive motor and the driven wheel are mounted on a mounting frame 71. The drive wheel is connected to the output shaft of the drive motor. The two ends of the conveyor belt 731 are respectively wound around the first drive wheel and the first driven wheel. The transfer support 72 is fixed to a set position on the conveyor belt 731. In this way, the first drive motor can drive the conveyor belt 731 to rotate, thereby driving the transfer support 72 to move along the X-axis. In order to make the movement of the transfer support 72 more stable, the mounting frame 71 can be provided with a guide rail, and the transfer support 72 is slidably connected to the guide rail. Reference Figure 11 The Z-axis moving assembly 75 includes a Z-axis guide rail and a Z-axis drive component. The Z-axis guide rail is fixed on the transfer support 72, and the tape preparation bracket 1 is slidably connected to the Z-axis guide rail. The Z-axis drive component is used to drive the tape preparation bracket 1 to move along the Z-axis direction.

[0041] In use, adjust the position of the mounting bracket 71 so that the tape picking mechanism 6 is positioned above the tape segment 100 placement position; move the tape picking mechanism 6 to directly above the tape segment 100 placement position via the X-axis moving component 73, and then drive the tape preparation bracket 1 via the Z-axis moving component 75, thereby moving the tape picking mechanism 6 downward, so as to place the tape segment picked up by the tape picking mechanism 6 at the set position.

[0042] Reference Figure 12 The transfer mechanism 7 also includes a Y-axis moving assembly 74, which includes a rodless cylinder mounted on the transfer support 72. The tape segment 100 picked up by the tape picking mechanism 6 is placed on the workpiece to be processed. The tape cutting and placing device also includes a tape pressing mechanism 81, which is connected to the transfer mechanism 7. The tape pressing mechanism 81 includes a tape pressing head drive 811 and a tape pressing head 812. The tape pressing head drive 811 drives the tape pressing head 812 to move, pressing the tape segment 100 onto the workpiece to be processed. In this embodiment, the tape pressing head drive 811 is a cylinder, fixed to the sliding part of the rodless cylinder, and the tape pressing head 812 is fixed to the piston rod end of the tape pressing head drive 811. After the tape segment 100 is placed on the workpiece to be processed, the tape head drive 811 drives the tape head 812 downward to press the tape segment 100 firmly on the workpiece to prevent the tape segment 100 from shifting.

[0043] In the embodiment where the tape cutting and placement device is applied to the busbar stringing machine, the tape pressing head 812 has two usage scenarios: the first scenario: refer to... Figure 13In the first case, the busbar is placed on the bending platform and needs to be transferred to the photovoltaic module. Therefore, the width W of the adhesive tape head 812 should be smaller than the width of the busbar, so as to press the tape segment 100 tightly onto the busbar, but not onto the tape segment 100 and the bending platform. In the second case, the busbar has already been placed on the photovoltaic module and is waiting for subsequent welding. Therefore, the width W of the adhesive tape head 812 should be larger than the width of the busbar, so as to fix the busbar and the photovoltaic module through the tape segment 100.

[0044] Example 2 This embodiment provides a tape cutting and placement device, which has a structure that is roughly the same as the tape cutting and placement device in Embodiment 1. The difference is that this embodiment does not have a tape pressing mechanism 81, and the Y-axis moving component 74 is connected to the workpiece picking mechanism 82 for transmission.

[0045] Reference Figure 14 The tape segment 100 picked up by the tape picking mechanism 6 is used to place on the workpiece to be processed, and multiple workpieces to be processed are stored in the hopper; the tape cutting and placing device also includes a workpiece picking mechanism 82 that is connected to the transfer mechanism 7. The workpiece picking mechanism 82 includes a suction cup drive 821, a suction cup fixing plate 822 and multiple suction cups 823. The multiple suction cups 823 are all fixed on the suction cup fixing plate 822. The suction cup drive 821 is used to drive the suction cup fixing plate 822 to move so that the suction cups 823 can pick up the workpieces to be processed in the hopper.

[0046] Specifically, the suction cup drive component 821 is configured as a cylinder, which is fixed to the rodless cylinder in the Y-axis moving assembly 74; the suction cup fixing plate 822 is fixed to the piston rod end of the suction cup drive component 821, and multiple suction cups 823 are all connected to the vacuum generator.

[0047] The tape cutting and placement device provided in this embodiment can place the tape segment 100 on the workpiece after it has been transferred to the set position. It has advantages such as compact structure, high work efficiency and low cost.

[0048] Example 3 This embodiment provides a busbar stringing machine, which includes the tape cutting and placement device described in any of the above embodiments. During use, the busbar stringing machine can be equipped with a tape pressing mechanism 81 or a workpiece suction mechanism 82 on the Y-axis moving assembly 74, depending on the actual application. The tape pressing head drive 811 and the suction cup drive 821 are interchangeable.
