Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a PTFE cloth tearing mechanism and busbar shaping equipment. Background Art

[0002] The busbar is an electrical connection component that passes through the inside of the battery module. A through hole is opened on the surface of the solar cell module, and the busbar passes through the through hole. The PTFE cloth is laid at the position where the busbar passes through the module to solve the problem of glue overflow at the place where the busbar passes through the surface of the module. After the PTFE cloth is laid, the busbar passes through the PTFE cloth and is flattened to both sides.

[0003] During the preparation of photovoltaic modules, one of the steps is to tear off the PTFE cloth and shape the busbars. Tearing off the PTFE cloth means removing the PTFE cloth from the module, and shaping the busbars means shaping the busbars that originally passed through the PTFE cloth and were flattened on the upper surface of the PTFE cloth into a vertical state for the next step.

[0004] In the prior art, the removal of the PTFE cloth is generally performed by using two oppositely arranged clamps, which clamp the two sides of the PTFE cloth respectively and move simultaneously to remove the PTFE cloth on the component. However, in this method, since the busbar is flattened on the PTFE cloth before removing the PTFE cloth, the busbar will block the removal action by directly clamping and removing it, resulting in incomplete tearing and easy damage to the busbar. During the movement, the damaged PTFE cloth fragments fall on the upper surface of the component, which has an adverse effect on production.

[0005] Therefore, it is necessary to improve the prior art to overcome the above defects. Utility Model Content

[0006] In order to improve the problem in the related art that the method of removing the PTFE cloth is easily affected by the bus bar, resulting in incomplete removal and damage to the bus bar, the present application provides a PTFE cloth tearing mechanism and a bus bar shaping device.

[0007] On the one hand, the present application provides a PTFE cloth tearing mechanism that adopts the following technical solutions:

[0008] A PTFE cloth tearing mechanism includes a Z-axis moving component and a scraping component. The scraping component includes relatively arranged scraping claws, which are used to clamp the two sides of the PTFE cloth. It also includes a pre-shoveling component, which acts on the PTFE cloth and is used to pre-shovel the PTFE cloth before the scraping component clamps the PTFE cloth. The Z-axis moving component drives the scraping component and the pre-shoveling component to move up and down along the Z-axis direction.

[0009] Optionally, the pre-shoveling assembly includes a mounting block and a pre-shoveling claw, the pre-shoveling claw is rotatably set on the mounting block, a slope is provided on the side of the pre-shoveling claw close to the Teflon cloth, and a torsion spring is connected between the mounting block and the pre-shoveling claw. When the torsion spring is in a natural state, the shoveling claw forms an acute angle with the surface of the battery assembly.

[0010] Optionally, the pre-scooping assembly further includes a Y-axis moving assembly, and the movable end of the Y-axis moving assembly is used to control the pre-scooping claw to move toward the direction close to the PTFE cloth.

[0011] Optionally, a fixed block is further provided on the mounting block, and the fixed block is located between the two shovel claws. A photoelectric sensor is provided on the fixed block, and the sensing end of the photoelectric sensor faces downward. The fixed block is provided with a detection hole for the photoelectric sensor to detect the Teflon cloth. The photoelectric sensor is used to detect whether the shoveling component clamps the Teflon cloth on the component.

[0012] Optionally, two pre-scooping claws are provided, and the two pre-scooping claws are respectively located on both sides of the mounting block, and the two pre-scooping claws respectively act on two sides of the busbar that are away from each other.

[0013] Optionally, the Z-axis moving assembly is further connected to a fixed bracket, and an air outlet pipe is provided on the fixed bracket, and the air outlet of the air outlet pipe is used to blow air towards the PTFE cloth.

[0014] Optionally, when the torsion spring is in a natural state, the angle between the shovel claw and the surface of the battery assembly is 5°~20°.

[0015] On the other hand, the present application provides a busbar shaping device that adopts the following technical solution:

[0016] A busbar shaping device comprises a shaping mechanism and the PTFE cloth tearing mechanism described in the first aspect, wherein the PTFE cloth tearing mechanism is used for tearing off the PTFE cloth, and the shaping mechanism is used for shaping the busbar.

[0017] In summary, this application has at least the following beneficial effects:

[0018] 1. When the pre-shoveling claws are pre-shoveling the PTFE sheet, they act on the bottom of the sheet and are located on the side away from the busbars. During the lifting process of the pre-shoveling claws, the busbars are lifted at a certain angle by the pre-shoveling claws, making it easier for the claws to grip the PTFE sheet and tear it off the component surface. This also improves the tearing effect of the PTFE sheet, making it less likely to be affected by the busbars and less likely to be damaged during the tearing process.

[0019] 2. When the Z-axis moving assembly drives the pre-scooping claw downward and contacts the surface of the battery module, the claw rotates, stretching the corresponding torsion spring. When the pre-scooping claw is lifted, the torsion spring returns the claw to its original angle, creating an acute angle between the claw and the module surface. This facilitates the claw's penetration and pre-scooping of the PTFE cloth.

[0020] 3. The air outlet pipe blows air to the PTFE cloth, and the edge of the PTFE cloth is easily blown to a certain height, which is convenient for the pre-shoveling claws to pre-shovel the PTFE cloth and also convenient for the shoveling claws to clamp the two sides of the PTFE cloth.

[0034] Refer to the attached Figure 1 The busbar 12 is an electrical connection component that passes through the interior of the battery assembly 11. A through hole is provided on the surface of the solar cell assembly 11, and the busbar 12 passes through the hole. The PTFE cloth 3 is laid on the position where the busbar 12 passes through the assembly to solve the problem of glue overflow. When the PTFE cloth 3 is laid on the assembly, the state of the PTFE cloth 3 and the busbar 12 is as follows: Figure 1 As shown, the existing process is to tear off the PTFE cloth 3 and shape the bus bar 12. The bus bar 12 shaping and the PTFE cloth 3 tearing are integrated into a bus bar shaping device. The shape of the bus bar 12 after tearing off the PTFE cloth 3 and shaping the bus bar 12 is shown in FIG. Figure 2 .

[0035] In the prior art, the removal of the PTFE sheet 3 is generally performed using two opposing shovel claws 2, which grip the two sides of the PTFE sheet 3 and move simultaneously to remove the PTFE sheet 3 from the assembly. After the PTFE sheet 3 is removed, the busbar 12 is reshaped. However, the shape of the busbar 12 before the PTFE sheet 3 is removed can hinder the removal of the PTFE sheet 3, which can easily lead to incomplete removal and damage to the busbar during the removal process. The present application provides a structure that can improve the effectiveness of PTFE sheet removal and reduce damage to the busbar during the PTFE sheet removal process.

[0036] The following is combined with Figure 3-6 , further explain this application in detail.

[0037] On the one hand, the present application provides a PTFE cloth tearing mechanism, which includes a Z-axis moving component 1, a fixed bracket 13, a scraping component and a pre-shoveling component. The Z-axis moving component 1 is used to drive the fixed bracket 13, the scraping component and the pre-shoveling component to move up and down along the Z-axis direction. An air outlet pipe 14 is provided on the fixed bracket 13, and the air outlet of the air outlet pipe 14 is aligned with the PTFE cloth 3. The air outlet pipe 14 is used to connect to an air supply equipment such as a blower or a hair dryer to blow air to the PTFE cloth 3 through the air outlet. Since the air outlet pipe 14 is connected to the air supply equipment to blow air, which is a prior art, this application will not elaborate on it.

[0038] The scraping assembly includes a driving component and two relatively arranged shovel claws 2, the driving component is used to drive the shovel claws 2 to clamp the two sides of the PTFE cloth 3, the pre-shoveling assembly is set between the two clamping claws, the pre-shoveling assembly acts between the two clamping claws, and the pre-shoveling assembly is used to pre-shovel the PTFE cloth 3 before the scraping assembly clamps the PTFE cloth 3. The pre-shoveling assembly includes a Y-axis moving assembly 8, a mounting block 4 and a pre-shoveling claw 5. The mounting block 4 is connected to the movable end of the Y-axis moving assembly 8, and the pre-shoveling claw 5 is rotatably set on the mounting block 4. A torsion bar is also provided between the mounting block 4 and the pre-shoveling claw 5. Spring 7, when the torsion spring 7 is in a natural state, the shovel claw 2 and the surface of the battery assembly 11 form an acute angle, and the angle between the shovel claw 2 and the battery assembly 11 is 5°~20°. As an implementable method, the angle can be 10° or 15°. Through such a setting, when the Z-axis moving component 1 drives the shovel claw 2 to move downward, if it contacts the surface of the battery assembly 11, the shovel claw will rotate, and the corresponding torsion spring 7 will be in a stretched state. When the shovel assembly is lifted, the torsion spring will drive the shovel claw to restore its original angle, which has the effect of protecting the battery assembly.

[0039] The Y-axis moving component 8 is used to control the pre-scooping claw 5 to move toward the direction of the PTFE cloth 3. When the pre-scooping component performs a pre-scooping action on the PTFE cloth 3, the Z-axis moving component 1 first controls the pre-scooping component to move downward, and then the Y-axis moving component 8 controls the pre-scooping claw 5 to move toward the direction of the PTFE cloth 3. The pre-scooping claw 5 provided in this application has two, and the two pre-scooping claws 5 are arranged opposite to each other. The pre-scooping claws 5 act on the bottom of the PTFE cloth 3 and on the side of the bus bar 12 away from each other. The Z-axis moving component 1 controls the scooping claw 2 to rise upward, thereby realizing a pre-scooping action on the PTFE cloth 3. During the pre-scooping process, the bus bar 12 has been lifted to a certain angle under the action of the pre-scooping claw 5. In this way, when the subsequent shoveling component clamps the PTFE cloth 3, the PTFE cloth 3 is not easily blocked by the bus bar 12, and the PTFE cloth 3 can be better clamped.

[0040] Reference Figure 5 , a fixing block 9 is further provided on the mounting block 4, and the fixing block 9 is located between the two shovel claws 2. A photoelectric sensor 10 is provided on the fixing block 9, and the sensing end of the photoelectric sensor 10 faces downward. The fixing block 9 is provided with a detection hole for the photoelectric sensor 10 to detect the polytetrafluoroethylene cloth 3. The photoelectric sensor 10 is used to detect whether the scraping mechanism clamps the polytetrafluoroethylene cloth 3 on the component. The signal interface of the photoelectric sensor 10 is connected to the controller, and the controller can be connected to the display device. When the photoelectric sensor 10 does not detect the polytetrafluoroethylene cloth 3 on the clamping claw, it is determined that the polytetrafluoroethylene cloth 3 is not successfully clamped, and the display is displayed. Since the technical means of sensing objects and giving prompts by the photoelectric sensor 10 is an existing technology, it will not be described in detail here.

[0041] On the other hand, Figure 6As shown, the present application provides a busbar shaping device, including a frame, an X-axis moving assembly, a shaping mechanism 16 and the first aspect of the PTFE cloth tearing mechanism 15, the PTFE cloth tearing mechanism 15 is used to tear off the PTFE cloth 3, the shaping mechanism 16 is used to shape the busbar 12, the X-axis moving assembly is used to control the X-axis movement of the shaping mechanism 16 and the PTFE cloth tearing mechanism, when the PTFE cloth tearing mechanism 15 clamps the PTFE cloth 3, the X-axis moving assembly drives the PTFE cloth tearing mechanism to move, thereby moving the PTFE cloth 3 out of the working area of the battery assembly 11.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
