Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and more specifically, to a tool for repairing adhesive dots using the OBB process. Background Technology

[0002] The grid lines used on photovoltaic cells are silver-supported strips attached to the cell surface. These consist of main grids and fine grids, with the main grids being thicker. After current is generated, it flows through the fine grids to the main grids, and then from there to the solder ribbon for discharge. OBB (Zero Busbar) technology is an innovative technique in photovoltaic cell manufacturing. It eliminates the silver electrodes of the main grids on the cell, replacing them with solder ribbons that directly interconnect with the fine grids to collect current from them. On one hand, this technology effectively reduces silver loss. On the other hand, compared to the 0.2-0.4mm diameter solder ribbons used in MBB (Multi-Busbar Technology in photovoltaics, defined as an advanced manufacturing process that optimizes current collection efficiency by increasing the number of main grids on the cell surface), the OBB process uses 0.2mm diameter solder ribbons, resulting in a smaller shading area and shorter current transmission distance, thus reducing power loss and improving power generation efficiency. The main 0BB process typically includes the following stringing methods: dispensing, welding dispensing, etc.

[0003] In general, the dispensing mechanism of the equipment used in the OBB process when employing welding and dispensing stringing is composed of a high-precision dispensing valve. Because the adhesive used by this dispensing valve has poor fluidity (adhesive viscosity greater than 5000 mPa·s), when the equipment is stopped or the dispensing valve outlet is not cleaned in time, the adhesive will block the outlet, thus affecting the dispensing volume or causing no dispensing at all. This will affect the shape of the dispensing, resulting in defects such as missing dispensing or small dispensing during the dispensing process, leading to technical problems such as scrapped battery cells. Summary of the Invention

[0004] This application provides a glue dot repair tool for the OBB process, which can improve production yield and reduce scrapped battery cells caused by missing glue dots or small glue dots.

[0005] In a first aspect, embodiments of this application provide a tool for repairing adhesive dots in an OBB process, including a housing, a photocuring assembly, a metering dispensing valve, a dispensing needle, and a photosensitive adhesive supply container. One end of the housing has an opening, and an internal receiving space is provided within the housing. The photocuring assembly includes a mounting base, a power supply, and a curing lamp switch. The mounting base is located at the opening and houses the curing lamp assembly. The power supply is located within the receiving space, and the curing lamp switch is located within the housing. The curing lamp assembly, the power supply, and the curing lamp switch are electrically connected. The metering dispensing valve is located within the receiving space. The end of the metering dispensing valve near the mounting base is its outlet end, and the end away from the mounting base is its inlet end. The dispensing needle passes through the mounting base, and the inlet end of the dispensing needle communicates with the outlet end of the metering dispensing valve. The outlet end of the dispensing needle extends outward to the outside of the housing.

[0006] In the above technical solution, a dispensing structure, mainly composed of a metering dispensing valve, a dispensing needle, and a photosensitive adhesive supply container, is first used. A photocuring structure, mainly composed of a mounting base, a curing lamp assembly, a power supply, and a curing lamp switch, is then used. The dispensing and photocuring structures work together to repair dispensing defects on the solar cells. Specifically, the metering dispensing valve draws photosensitive adhesive from the supply container through the dispensing needle and drips it onto areas of the solar cell that are not dispensed or have small dispensing dots. Then, the photocuring lamp assembly is activated to cure the adhesive droplets on the solar cell. This achieves the technical effect of improving production yield and reducing the number of scrapped solar cells caused by missing or small dispensing dots compared to existing technologies.

[0007] In some embodiments, the photocuring assembly further includes a time-delay switch module disposed in the receiving space, and the time-delay switch module, the curing lamp assembly, the power supply, and the curing lamp assembly are electrically connected.

[0008] In the above technical solution, by connecting the delay switch module to the curing lamp group, the power supply and the curing lamp group switch, the opening time of the curing lamp group 22 can be delayed through the delay switch module.

[0009] In some embodiments, the mounting base includes a mounting hole, and the curing lamp assembly includes a plurality of curing lamp beads, which are evenly distributed along a circumference formed with the mounting hole as the center.

[0010] In the above technical solution, by uniformly distributing multiple curing lamp beads along the circumference formed with the mounting hole as the center, the area irradiated by the multiple curing lamp beads is increased, thereby enabling the irradiation area to completely cover the surface of the adhesive droplet.

[0011] In some embodiments, a protective sleeve is provided on the discharge end of the dispensing needle.

[0012] In the above technical solution, the protective sleeve prevents the dispensing needle from directly contacting the battery cell during the dispensing process, thereby reducing the probability of damage to the surface of the battery cell.

[0013] In some embodiments, a connecting pipe is further included, wherein the outlet end of the connecting pipe is fixedly connected to the inlet end of the metering dispensing valve, and the inlet end of the connecting pipe is detachably connected to the outlet end of the photosensitive adhesive supply container.

[0014] In the above technical solution, a connecting pipeline is provided to connect the photosensitive adhesive supply container to the metering dispensing valve, so that the photosensitive adhesive in the photosensitive adhesive supply container can enter the metering dispensing valve according to the specified path.

[0015] In some embodiments, the discharge end of the connecting pipe is provided with an external thread, and the discharge end of the photosensitive adhesive supply container is provided with an internal thread that mates with the external thread.

[0016] In the above technical solution, the photosensitive adhesive supply container and the connecting pipeline can be detachably connected by the threaded engagement of the external and internal threads, thereby facilitating the replacement of the photosensitive supply container.

[0017] In some embodiments, the discharge end of the connecting pipe is provided with a slot, and the discharge end of the photosensitive adhesive supply container is provided with a buckle that engages with the slot.

[0018] In the above technical solution, the photosensitive adhesive supply container and the connecting pipeline can be detachably connected by the snap-fit ​​and the slot, which facilitates the replacement of the photosensitive supply container.

[0019] In some embodiments, the device further includes a grip and a trigger, the grip being rotatably connected to the housing, one end of the trigger being connected to the grip, and the other end of the trigger being connected to the switch of the metering dispensing valve.

[0020] In the above technical solution, by setting a trigger and connecting one end of the trigger to the handle and the other end to the switch of the metering dispensing valve, the operator can hold the handle and use the handle to drive the trigger to activate the switch of the metering dispensing valve, thereby opening the metering dispensing valve and making it easier for the operator to operate the glue dot repair tool.

[0021] In some embodiments, a pivot is provided at one end of the handle near the housing, and a pivot mounting seat is provided on the housing, with the pivot rotatably connected to the pivot mounting seat.

[0022] In the above technical solution, the rotating shaft is rotatably connected to the rotating shaft mounting base, so that when the rotating shaft rotates relative to the rotating shaft mounting base, it can drive the handle to rotate relative to the housing.

[0023] In some embodiments, the trigger sleeve is provided with a return spring, one end of which abuts against the handle and the other end of which abuts against the housing.

[0024] In the above technical solution, by setting a return spring, with one end of the return spring abutting against the handle and the other end abutting against the housing, the return spring can be compressed when the handle is rotated. Under the action of elasticity, the return spring can reset the handle, thus making it easier for the operator to hold the glue dot repair tool. Attached Figure Description

[0034] In general, when using the welding and dispensing stringing method in the OBB process, the dispensing mechanism of the equipment consists of a high-precision dispensing valve. Because the adhesive used by this dispensing valve has poor fluidity, when the equipment is stopped or the dispensing valve outlet is not cleaned in time, the adhesive will block the outlet, thus affecting the dispensing volume or causing no dispensing. This affects the shape of the dispensing, resulting in defects such as missing dispensing or small dispensing during the dispensing process, which leads to technical problems such as scrapping of the battery cells.

[0035] Based on the above considerations, in order to solve the technical problem of the glue dispensing valve affecting the shape of the glue, resulting in defects such as missing glue or small glue size during the dispensing process and causing scrapping of battery cells, this application provides a glue dot repair tool for OBB process, including a housing, a photocuring component, a metering dispensing valve, a dispensing needle, and a photosensitive adhesive supply container. One end of the housing has an opening, and the housing has an internal receiving space. The photocuring component includes a mounting base, a power supply, and a curing lamp switch. The mounting base is located at the opening and houses the curing lamp assembly. The power supply is located in the receiving space, and the curing lamp switch is located in the housing. The curing lamp assembly, power supply, and curing lamp switch are electrically connected. The metering dispensing valve is located in the receiving space. The end of the metering dispensing valve near the mounting base is the outlet end, and the end away from the mounting base is the inlet end. The dispensing needle passes through the mounting base, and the inlet end of the dispensing needle is connected to the outlet end of the metering dispensing valve. The outlet end of the dispensing needle extends outward to the outside of the housing.

[0036] In this adhesive spot repair tool, a metering dispensing valve is first installed inside the housing. The outlet end of the metering dispensing valve is connected to a dispensing needle, and the inlet end of the metering dispensing valve is connected to a photosensitive adhesive supply container. The dispensing needle passes through a mounting base, and the outlet end of the dispensing needle extends outward to the outside of the housing. This allows the metering dispensing valve to draw a metered amount of photosensitive adhesive from the photosensitive adhesive supply container through the dispensing needle and drip it onto areas of the solar cell that have not been dispensed or have small dispensing dots. Next, a photocuring assembly is installed at the opening of the housing. The photocuring assembly includes a mounting base, a power supply, and a curing lamp switch. The mounting base is equipped with a curing lamp assembly, and the curing lamp assembly, power supply, and curing lamp switch are electrically connected. The curing lamp assembly can be controlled to turn on and off via the curing lamp switch. After the metering dispensing valve finishes dispensing, turning on the curing lamp assembly cures the adhesive droplets on the solar cell, thus completing the repair of dispensing defects on the solar cell. This technology improves production yield and reduces scrapped battery cells caused by missing or poorly applied adhesive compared to existing technologies.

[0037] Please refer to Figure 1 , Figure 1 This is a structural diagram of an OBB process adhesive dot repair tool provided in some embodiments of this application. Embodiments of this application provide an OBB process adhesive dot repair tool, including a housing 1, a photocuring assembly 2, a metering dispensing valve 3, a dispensing needle 4, and a photosensitive adhesive supply container 5. The housing 1 has an opening 11 at one end, and an accommodating space 12 inside the housing 1. The photocuring assembly 2 includes a mounting base 21, a power supply 23, and a curing lamp switch 24. The mounting base 21 is located at the opening 11 and houses a curing lamp assembly 22. The power supply 23 is located in the accommodating space 12, and the curing lamp switch 24 is located in the housing 1. The curing lamp assembly 22, the power supply 23, and the curing lamp switch 24 are electrically connected. The metering dispensing valve 3 is located in the accommodating space 12. The end of the metering dispensing valve 3 closest to the mounting base 21 is the outlet end of the metering dispensing valve 3, and the end of the metering dispensing valve 3 furthest from the mounting base 21 is the inlet end of the metering dispensing valve 3. The dispensing needle 4 passes through the mounting base 21. The inlet end of the dispensing needle 4 is connected to the outlet end of the quantitative dispensing valve 3. The outlet end of the dispensing needle 4 extends outward to the outside of the housing 1.

[0038] The housing 1 is used to house the various components that make up the adhesive dot repair tool. The housing 1 can be a hollow structure with an opening 11 at one end. The housing 1 can be in various shapes, such as cylindrical, cuboid, etc. The housing 1 can be made of various materials, such as copper, iron, aluminum, steel, aluminum alloy, etc.

[0039] The curing lamp assembly 22 can be a curing lamp bead 221, a curing lamp strip, etc.

[0040] The metering dispensing valve 3 can be a pneumatic metering dispensing valve, an electric metering dispensing valve, etc. The pneumatic metering dispensing valve is driven by compressed air entering its drive chamber, creating a pressure difference. This pressure difference pushes moving parts such as pistons or diaphragms, causing them to displace and thus controlling the flow of adhesive. The electric metering dispensing valve is driven by energizing an electromagnetic coil, generating a magnetic field. This magnetic force acts on the valve core and other components, causing them to overcome spring forces and other resistances, thus opening and closing the valve and controlling the flow of adhesive. Compared to pneumatic metering dispensing valves, electric metering dispensing valves have a faster response speed and can precisely control the timing and amount of dispensing.

[0041] The dispensing needle 4 can be a thin-walled needle. The thin-walled structure of the thin-walled needle can generate a large flow output with a small pressure.

[0042] The photosensitive adhesive supply container 5 is used to hold the photosensitive adhesive, which can be UV adhesive (ultraviolet curing adhesive), visible light curing adhesive, near-infrared light curing adhesive, etc.

[0043] The photosensitive adhesive supply container 5 can be in various shapes, such as cylindrical or cuboid. To facilitate the assembly of the photosensitive adhesive supply container 5, the shape of the photosensitive adhesive supply container 5 can also match the shape of the shell 1.

[0044] The discharge end of the photosensitive adhesive supply container 5 and the inlet end of the metering dispensing valve 3 can be directly connected or indirectly connected.

[0045] In this embodiment, firstly, a quantitative dispensing valve 3 is installed inside the housing 1, and the outlet end of the quantitative dispensing valve 3 is connected to the dispensing needle 4. The inlet end of the quantitative dispensing valve 3 is connected to the photosensitive adhesive supply container 5. The dispensing needle 4 passes through the mounting base 21, and the outlet end of the dispensing needle 4 extends outward to the outside of the housing 1. In this way, the photosensitive adhesive in the photosensitive adhesive supply container 5 can be quantitatively drawn out from the dispensing needle 4 through the quantitative dispensing valve 3 and dripped onto the area of ​​the battery cell that has not been dispensed or has a small amount of dispensed adhesive. Secondly, a photocuring assembly 2 is installed at the opening 11 of the housing 1. The photocuring assembly 2 includes a mounting base 21, a power supply 23, and a curing lamp switch 24. A curing lamp 22 is provided on the mounting base 21, and the curing lamp 22, the power supply 23, and the curing lamp switch 24 are electrically connected. This allows the curing lamp assembly 22 to be turned on and off via the curing lamp assembly switch 24. After the dispensing by the metering valve 3 is complete, turning on the curing lamp assembly 22 will cure the adhesive droplets that have fallen onto the battery cell, thus repairing the dispensing defects on the battery cell. This achieves the technical effect of improving production yield and reducing the number of scrapped battery cells caused by missing or poorly dispensed adhesive.

[0046] In some embodiments, please refer to Figure 1The light curing component 2 also includes a delay switch module 25, which is located in the receiving space 12. The delay switch module 25, the curing lamp group 22, the power supply 23 and the curing lamp group switch 25 are electrically connected.

[0047] The delay switch module 25 can be an RC delay circuit, a common electronic component used to control the delay time of current or voltage. It consists of a resistor and a capacitor, and the delay function is achieved through the interaction of these two components. Different resistor and capacitor specifications can be selected according to the required delay time to achieve the corresponding function. For example, in this embodiment, if a 2-3 second delay is required for the curing lamp assembly to turn on, resistors and capacitors with different values ​​can be selected based on this requirement.

[0048] In this embodiment, the delay switch module 25 is electrically connected to the curing lamp group 22, the power supply 23, and the curing lamp group switch 25. This allows the curing lamp group 22 to be turned on prematurely. Since the photosensitive adhesive typically takes 2-3 seconds to drip from the dispensing needle 4 through the metering dispensing valve 3 onto the battery cell, if the operator accidentally operates the curing lamp group switch 24 during this time, the curing lamp group 22 will turn on prematurely during the dripping process, curing the adhesive droplets and affecting the dispensing process. Therefore, the delay function of the delay switch module 25 can reduce the impact of operator error on the dispensing process.

[0049] In some embodiments, please refer to Figure 2 , Figure 2 for Figure 1 The bottom view. The mounting base 21 includes a mounting hole 211, and the curing lamp assembly 22 includes a plurality of curing lamp beads 221, which are evenly distributed along a circumference formed with the mounting hole 21 as the center.

[0050] Mounting hole 21 is used to mount dispensing needle 4.

[0051] The curing lamp assembly includes 6 curing lamp beads, 8 curing lamp beads, etc. The curing lamp beads 211 can be ultraviolet lamp beads, blue lamp beads, white lamp beads, near-infrared lamp beads, etc. In the embodiment where the photosensitive adhesive is UV adhesive (ultraviolet curing adhesive), the curing lamp beads 211 can be ultraviolet lamp beads.

[0052] In this embodiment, by uniformly distributing multiple curing lamp beads 221 along a circumference formed with the mounting hole 21 as the center, the area irradiated by the multiple curing lamp beads 221 is increased, thereby allowing the irradiated area to completely cover the surface of the adhesive droplet, resulting in a better curing effect of the adhesive droplet.

[0053] In some embodiments, please refer to Figure 1The dispensing end of the dispensing needle 4 is fitted with a protective sleeve 41.

[0054] The protective sleeve 41 can be a silicone sleeve, a rubber sleeve, etc.

[0055] In this embodiment, the protective sleeve 41 prevents the dispensing needle 4 from directly contacting the battery cell during the dispensing process, thereby reducing the probability of damage to the surface of the battery cell.

[0056] In some embodiments, please refer to Figure 1 It also includes a connecting pipe 6, the outlet end of the connecting pipe 6 is fixedly connected to the inlet end of the quantitative dispensing valve 4, and the inlet end of the connecting pipe 6 is detachably connected to the outlet end of the photosensitive adhesive supply container 5.

[0058] In some embodiments, please refer to Figure 1 The discharge end of the connecting pipe 6 is provided with an external thread 61, and the discharge end of the photosensitive adhesive supply container 5 is provided with an internal thread 51 that is threadedly engaged with the external thread 61.

[0063] In this embodiment, a buckle ( Figure 1 (not shown in the image) and card slot ( Figure 1 The snap-fit ​​mechanism (not shown in the image) enables the photosensitive adhesive supply container 5 to be detachably connected to the connecting pipe 6, thus facilitating the replacement of the photosensitive supply container 5.
