Description

Technical Field

[0001] This application relates to the field of curing equipment technology, and in particular to a battery cell sintering production line. Background Technology

[0002] Currently, after four screen printing processes, the transfer flow of heterojunction solar cells into and out of the cassette curing oven is as follows: Solar cells are transferred via a telescopic belt to a basket; full baskets are then transferred to upper loading basket transition stations 1 and 2. Next, a loading servo basket clamping and lifting module (CCD positioning, lifting, lateral movement, 90° rotation, descent, and reset) grasps and moves the full basket to the cassette curing oven loading station module. The cassette curing oven conveyor chain then enters the oven for curing. After curing, the unloading servo basket clamping and lifting module grasps and moves the full basket to upper unloading basket transition stations 1 and 2, and then the telescopic belt transfers the solar cells to the rear end. During this process, empty baskets are lowered via a basket lifting module to lower unloading basket transition stations 1 and 2. The material is returned from the second module of the unloading basket lifting station to the basket return station, and then transferred to the loading basket lifting module via the loading basket lifting and transition station.

[0003] This setup results in the following disadvantages for basket-type solar cell transportation: 1. The scheme of loading and unloading solar cells into and out of the furnace with full baskets involves numerous and complex mechanical modules and a wide variety of electrical components, which is detrimental to on-site equipment maintenance. 2. The current scheme uses expensive camera scanning and correction positioning modules (servo basket clamping and lifting modules) at multiple workstations, resulting in high equipment costs and contradicting the goal of cost reduction. 3. The servo basket clamping and lifting module may experience abnormal basket collisions, causing solar cell fragmentation and defects. 4. The servo basket clamping and lifting module has high maintenance costs, long CT operation time, and low efficiency. Utility Model Content

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0029] Currently, after four screen printing processes, the transfer flow of heterojunction solar cells into and out of the cassette curing oven is as follows: Solar cells are transferred to baskets via a telescopic belt. Full baskets are then transferred to the upper loading basket transition stations one and two. A loading servo basket clamping and lifting module (CCD positioning, lifting, lateral movement, 90° rotation, descent, and reset) then grips and moves the full basket to the loading station module of the cassette curing oven. The cassette curing oven transfer chain then enters the oven for curing. After the curing process is complete, the unloading servo basket clamping and lifting module grips and moves the full basket to the unloading upper basket transition stations one and two. The telescopic belt then transfers the solar cells to the rear end. This process involves numerous and complex mechanical modules and a wide variety of electrical components, making on-site equipment maintenance difficult.

[0030] In view of this, some embodiments of this application provide a battery cell sintering production line, which connects the first lifting mechanism and the second lifting mechanism through a transmission mechanism, so that the baskets on the battery cell sintering production line can be quickly transported from the second lifting mechanism to the transmission mechanism, and then transported from the transmission mechanism to the first lifting mechanism, so that the baskets can be reused. This effectively reduces the size of the auxiliary mechanism module for transporting baskets in the battery cell sintering production line. The overall structure of the equipment is simple, maintenance and operation are convenient, and it is easy to master on site.

[0031] The present application will be described in detail below through specific embodiments:

[0032] like Figure 1As shown, the flower basket return mechanism of this application embodiment includes: a first lifting mechanism 21, which is used to transport the flower basket 50 in a vertical direction; a second lifting mechanism 31, which is used to transport the flower basket 50 in a vertical direction, and the second lifting mechanism 31 and the first lifting mechanism 21 are spaced apart in a first direction; and a transmission mechanism 40, the first end of the transmission mechanism 40 is connected to the top end of the first lifting mechanism 21, the second end of the transmission mechanism 40 is connected to the top end of the second lifting mechanism 31, and the transmission mechanism 40 is used to transport the flower basket 50 in the first direction.

[0033] In this embodiment, the first lifting mechanism 21 is used to transport full flower baskets for the battery cell sintering production line, and the first lifting mechanism 21 can also accept empty flower baskets transported by the transmission mechanism 40. The second lifting mechanism 31 is used to receive full flower baskets transported by the battery cell sintering production line and transport empty flower baskets after the work is completed to the transmission mechanism 40. This allows the flower baskets 50 to be quickly reused on the battery cell sintering production line and effectively reduces the scale of the auxiliary mechanism module for transporting flower baskets in the battery cell sintering production line. The overall structure of the equipment is simple, maintenance and operation are convenient, and it is easy to master on site.

[0034] Furthermore, such as Figure 2 As shown, the first lifting mechanism 21 and the second lifting mechanism 31 include: a guide member 310, which is arranged in a vertical direction; a support frame 311, which is slidably connected to the guide member and is used to support the flower basket 50; and a driving member, which is transmissionally connected to the support frame 311 to drive the support frame to slide along the guide member 310.

[0035] In this embodiment, both the first lifting mechanism 21 and the second lifting mechanism 31 have a support frame 311, a guide member 310, and a driving member, so that both the first lifting mechanism 21 and the second lifting mechanism 31 can move in the vertical direction. This allows the first lifting mechanism 21 and the second lifting mechanism 31 to transport the flower basket 50 to the transmission mechanism 40 or to receive the flower basket 50 transported by the transmission mechanism 40 through the movement of the support frame 311, effectively ensuring the stability of the flower basket return mechanism in transporting the flower basket 50.

[0036] Specifically, the support frame 311 has a first working position that moves to the top of the guide member 310, and a second working position that moves to the middle part of the guide member 310. When the support frame 311 is in the first working position, the transmission mechanism 40 can pick up the flower basket 50. When the support frame 311 is in the second working position, the support frame 311 is flush with the height of the battery cell sintering production line.

[0037] In this embodiment, the support frame 311 has a first working position that moves to the top of the guide member 310, and a second working position that moves to the middle part of the guide member 310, so that when the support frame 311 is in the first working position, the transmission mechanism 40 can pick up the flower basket 50, and when the support frame 311 is in the second working position, the support frame 311 is flush with the height of the battery cell sintering production line, thereby ensuring that the flower basket 50 on the support frame 311 can be stably transported to the battery cell sintering production line.

[0038] Further, the transmission mechanism 40 includes: a first connector 41, the first end of which is connected to the top end of the guide 310 of the first lifting mechanism 21; a second connector 42, the first end of which is connected to the top end of the guide 310 of the second lifting mechanism 31; a return frame 43, the first end of which is connected to the second end of the first connector 41, and the second end of which is connected to the second end of the second connector 42; and a pickup component, which is disposed on the return frame 43 and is capable of reciprocating along the return frame 43. When the support frame 311 is in the first working position, the pickup component can pick up the flower basket 50 on the support frame 311.

[0039] In this embodiment, as Figure 1 , Figure 2 As shown, the transmission mechanism 40 includes a first connector 41, a second connector 42, a return rack 43, and a pickup component disposed on the return rack 43. The first end of the first connector 41 is connected to the top end of the guide 310 of the first lifting mechanism 21, and the first end of the second connector 42 is connected to the top end of the guide 310 of the second lifting mechanism 31. This arrangement allows the transmission mechanism 40 to be stably connected to the first lifting mechanism 21 and the second connector 42, effectively ensuring that the first connector 41 and the second connector 42 can transport the flower basket 50 to the transmission mechanism 40. The pickup component disposed on the return rack 43 effectively ensures the stable transport of the flower basket 50 on the return rack 43 and effectively prevents the flower basket 50 from falling off the return rack 43. In this application, the pickup component can use magnetic attraction, hooks, etc. to grab the flower basket 50, and there is no limitation on the pickup component.

[0040] Furthermore, the height of the first connector 41 is greater than or equal to the height of the flower basket 50.

[0041] In this embodiment, the height of the first connector 41 is greater than or equal to the height of the flower basket 50, so that when the support frame 311 moves from the second working position to the first working position, the flower basket 50 on the support frame 311 will not collide with the return rack 43, effectively ensuring the safety of the flower basket 50 on the support frame 311.

[0042] In another embodiment of this application, such as Figure 3As shown, a battery cell sintering production line is also provided, including a basket recirculation mechanism, which is the basket recirculation mechanism of the above embodiment.

[0043] Specifically, the battery cell sintering production line includes: a cassette furnace 10, which has a cavity with a feed inlet and a discharge outlet; a loading section 20, the first end of which is connected to the feed inlet; a unloading section 30, the first end of which is connected to the discharge outlet; a first lifting mechanism 21 of the basket return mechanism connected to the second end of the loading section 20; and a second lifting mechanism 31 of the basket return mechanism connected to the second end of the unloading section 30.

[0044] In this embodiment, the battery cell sintering production line includes a feeding section 20, a cassette furnace 10, and a discharging section 30. The first lifting mechanism 21 of the basket return mechanism is connected to the second end of the feeding section 20, and the second lifting mechanism 31 of the basket return mechanism is connected to the second end of the discharging section 30. This arrangement effectively ensures a stable connection between the battery cell sintering production line and the basket return mechanism, effectively ensuring the stable transportation of the basket 50. Furthermore, the integrated direct transmission design reduces the need for two sets of loading and unloading basket lifting station modules, two sets of servo basket clamping lifting modules, and four sets of loading and unloading basket transition station modules, effectively saving equipment procurement costs.

[0045] Furthermore, the feeding section 20 includes: a first lifting and rotating mechanism 22, the inlet of which is connected to a first lifting mechanism 21, the first lifting and rotating mechanism 22 being used to rotate and position the flower basket 50; a first transition station 23, the inlet of which is connected to the outlet of the first lifting and rotating mechanism 22, the first transition station 23 being used to position and place the flower basket 50 transported by the first lifting and rotating mechanism 22; a first guide wheel assembly 24, the inlet of which is connected to the outlet of the first transition station 23, the first guide wheel assembly 24 being used to transport the flower basket 50; and a feeding station 25, the inlet of which is connected to the outlet of the first guide wheel assembly 24, the outlet of which is connected to the inlet of the cavity, the feeding station 25 being used to transport the flower basket 50 to the gas cylinder 10.

[0046] In this embodiment, the feeding section 20 includes a first lifting and rotating mechanism 22, a first transition station 23, a first guide wheel group 24, and a feeding station 25. The first lifting and rotating mechanism 22 is used to rotate and position the flower basket 50 so that the flower basket 50 rotates 90° to facilitate the sintering of the electrolytic capacitor. The first transition station 23 is used to position and place the flower basket 50 transported by the first lifting and rotating mechanism 22. This arrangement effectively prevents collisions caused by too many flower baskets 50. The first guide wheel group 24 makes the flower basket 50 enter and arrange more orderly. The feeding station 25 is used to transport the flower basket 50 to the cassette furnace 10 so that the flower basket 50 enters the cassette furnace 10 in an orderly manner. The arrangement of the entire feeding section 20 ensures that the flower basket 50 is arranged more stably and orderly, effectively ensuring the working efficiency of the feeding section 20.

[0047] Furthermore, such as Figure 4 As shown, the first lifting and rotating mechanism 22 includes: a rotating cylinder 220, the driving end of which is used to carry the flower basket 50 and rotate the flower basket 50 at a preset angle; a lifting cylinder 222, the rotating cylinder 220 being disposed at the end of the lifting cylinder 222 and used to drive the rotating cylinder 220 to move vertically; and a transport component 221, which is used to transport the flower basket 50 on the first lifting mechanism 21 to the rotating cylinder 220, so as to transport the flower basket 50 on the rotating cylinder 220 to the first transition station 23.

[0048] In this embodiment, the first lifting and rotating mechanism 22 includes a rotary cylinder 220, a lifting cylinder 222, and a transport component 221. The rotary cylinder 220 is used to rotate the flower basket 50 to a preset angle, the lifting cylinder 222 is used to drive the rotary cylinder 220 to move vertically, and the transport component 221 is used to transport the flower basket 50 on the first lifting mechanism 21 to the rotary cylinder 220, so as to transport the flower basket 50 on the rotary cylinder 220 to the first transition station 23, so that the flower basket 50 can quickly and effectively enter the first transition station 23 from the first lifting and rotating mechanism 22, ensuring the working efficiency of the loading section 20. In this application, the rotary cylinder 220 and the lifting cylinder 222 can also be a single lifting and rotating cylinder, and the transport component 221 can be a clamp, a hook, etc., which is not limited here.

[0049] In another embodiment of this application, such as Figure 3As shown, the unloading section 30 includes: an unloading station 32, the inlet of which is connected to the outlet of the cavity, and the unloading station 32 is used to transport the flower basket 50 from the gas cylinder 10; a second guide wheel assembly 33, the inlet of which is connected to the outlet of the unloading station 32, and the second guide wheel assembly 33 is used to transport the flower basket 50; a second lifting and rotating mechanism 34, the inlet of which is connected to the outlet of the second guide wheel assembly 33, and the second lifting and rotating mechanism 34 is used to rotate and position the flower basket 50; and a second transition station 35, the inlet of which is connected to the outlet of the second lifting and rotating mechanism 34, and the outlet of which is connected to the second lifting mechanism 31, and the second transition station 35 is used to position and place the flower basket 50 transported by the second lifting and rotating mechanism 34.

[0050] In this embodiment, the unloading section 30 includes an unloading station 32, a second guide wheel group 33, a second lifting and rotating mechanism 34, and a second transition station 35. This arrangement allows the basket 50 from the gasifier 10 to quickly pass through the unloading section 30 and enter the second lifting mechanism 31, ensuring the convenience and stability of the basket 50's transportation. The second lifting and rotating mechanism 34 also includes a rotating cylinder 220, a lifting cylinder 222, and a transport component 221 to ensure stable transportation of the basket. After the first lifting mechanism 21 receives an empty basket, it descends to the belt conveyor position and begins to transfer battery cells into the empty basket. A full basket is transported to the first lifting and rotating mechanism 22 via the conveyor belt, where the clamping cylinder actuates to align the basket. The first lifting and rotating mechanism 22, located at the bottom of the module, begins to lift, and after completion, the rotating cylinder performs a 90° rotation. The basket descends to the belt conveyor position and continues to be transported to the first transition station 23. The cells continue to be conveyed directly to the loading station 25 via the first guide wheel set 24, and the basket 50 is transported to the gasifier furnace 10. After the process in the gasifier furnace 10 is completed, the full-size basket is conveyed directly to the second lifting and rotating mechanism 34 via the unloading station 32 and the second guide wheel set 33. At this time, after the full-size basket has completed the clamping, lifting, and rotating actions, it enters the second transition station 35, and then enters the second lifting mechanism 31. The conveyor belt begins to convey the cells out of the basket. After the cells are conveyed out, the second lifting mechanism 31 rises to the empty basket return station, waiting to enter the next full-size basket output cycle.
