Description

Technical Field

[0001] The utility model relates to the field of automation technology, in particular to a carrier conveying device and battery cell manufacturing equipment. Background Art

[0002] The manufacturing equipment for photovoltaic cells (cells) uses a chain conveyor mechanism to transport the carriers that carry the cells. As the conveying distance increases, the chain lengthens, making the chain prone to vibration and sagging. This can affect the processing accuracy of the cells and may even cause the chain and carrier to lose contact, making the carrier unable to be transported.

[0003] When the chain is longer and the number of carriers mounted on the chain increases, the energy consumption of the required reducer and motor will increase accordingly, which will increase the power cost. Utility Model Content

DETAILED DESCRIPTION

[0040] The following describes the preferred embodiments of the present invention in detail with reference to the accompanying drawings to make the advantages and features of the present invention more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation of the present invention. Example 1 is not just one example, but a collection of examples with similar schemes or features, and the same applies to the other examples.

[0041] Example 1

[0042] like Figures 1-6 As shown, this embodiment provides a carrier conveying device for battery cell manufacturing equipment, and the carrier conveying device includes a track 1, a chain conveying mechanism 2 and a transfer mechanism.

[0043] Track 1 is used to support the sliding movement of carrier 3, and track 1 extends along a first direction. In a specific embodiment, track 1 passes through the loading area, processing area, and unloading area of the battery cell manufacturing equipment. During operation, carrier 3 is placed on track 1 in the loading area, and carrier 3 slides along track 1 to the processing area. In the processing area, the product 100 carried by carrier 3 is processed. Carrier 3 then slides along track 1 to the unloading area and is removed from track 1.

[0044] The chain conveyor mechanism 2 is used to drive the carrier 3 to slide on the track 1. The chain conveyor mechanism 2 is arranged in a plurality of intervals along the extension direction of the track 1. The transfer mechanism is arranged between two adjacent chain conveyor mechanisms 2, and is used to transfer the carrier 3 transported by the upstream chain conveyor mechanism 2 to the downstream chain conveyor mechanism 2, so that the carrier 3 can continue to be transported on the downstream chain conveyor mechanism 2. In the conveying line of the carrier 3, a longer chain conveyor mechanism 2 is replaced by multiple shorter chain conveyor mechanisms 2, and a transfer mechanism is used to realize the transfer of the carrier 3 between two adjacent chain conveyor mechanisms 2, thereby completing the complete conveying of the carrier 3 in the conveying line. Therefore, the chain length of the chain conveyor mechanism 2 is shortened, the chain shaking amplitude can be reduced, the chain drooping amplitude can be reduced, the processing accuracy of the product 100 can be improved, and the risk of the chain and the carrier being out of coordination can be reduced. On the other hand, multiple shorter chain conveyor mechanisms 2 and the transfer mechanism each need to be equipped with a separate motor, but the total energy consumption is still less than the energy consumption of a longer chain conveyor mechanism 2.

[0045] In a specific embodiment, three chain conveyor mechanisms 2 are spaced apart along the extension direction of the track 1, and there are two transfer mechanisms. For example, the three chain conveyor mechanisms 2 spaced apart along the extension direction of the track 1 are labeled chain conveyor mechanism No. 1, chain conveyor mechanism No. 2, and chain conveyor mechanism No. 3. Transfer mechanism No. 1 is located between chain conveyor mechanism No. 1 and chain conveyor mechanism No. 2 to transfer carriers 3 from chain conveyor mechanism No. 1 to chain conveyor mechanism No. 2. Transfer mechanism No. 2 is located between chain conveyor mechanism No. 2 and chain conveyor mechanism No. 3 to transfer carriers 3 from chain conveyor mechanism No. 2 to chain conveyor mechanism No. 3. The track 1 passes through the loading, processing, and unloading areas of the battery cell manufacturing equipment. Chain conveyor mechanism No. 1 is located in the loading area, chain conveyor mechanism No. 2 is located in the processing area, and chain conveyor mechanism No. 3 is located in the unloading area. Transfer mechanism No. 1 is located at the junction of the loading and processing areas, and transfer mechanism No. 2 is located at the junction of the processing and unloading areas. A chain conveyor mechanism 2 is respectively provided in the loading area, processing area and unloading area of the battery cell manufacturing equipment to facilitate the repair and maintenance of the chain conveyor mechanism 2. When the chain conveyor mechanism 2 in the processing area is damaged, only the chain conveyor mechanism 2 needs to be repaired or replaced.

[0046] The carrier 3 is a support component for the product 100, which can be a silicon wafer, circuit board, or chip. The carrier 3 on the track 1 may or may not be loaded with a product. The upstream chain conveyor mechanism 2 is a chain conveyor mechanism 2 immediately upstream of the transfer mechanism, and the downstream chain conveyor mechanism 2 is a chain conveyor mechanism 2 immediately downstream of the transfer mechanism.

[0047] In a specific embodiment, a first matching portion 31a and a second matching portion are provided on the carrier 3, a third matching portion 21 is provided on the chain of the chain conveying mechanism 2, and a fourth matching portion is provided on the transfer mechanism. In the first preset position, the third matching portion 21 and the first matching portion 31a of the upstream chain conveying mechanism 2 are matched and connected, so that the upstream chain conveying mechanism 2 can drive the carrier 3 to move. In the second preset position, the third matching portion 21 and the first matching portion 31a of the upstream chain conveying mechanism 2 are disconnected, and the fourth matching portion and the second matching portion are matched and connected, so that the transfer mechanism can drive the carrier 3 to move. In the third preset position, the fourth matching portion and the second matching portion are disconnected, and the third matching portion 21 and the first matching portion 31a of the downstream chain conveying mechanism 2 are matched and connected, so that the downstream chain conveying mechanism 2 can drive the carrier 3 to move.

[0048] Preferably, the first mating portion 31a is a slot or block, and the third mating portion 21 is a mating block or slot, to reduce the risk of disengagement between the first mating portion 31a and the third mating portion 21. The second mating portion is a slot or block, and the fourth mating portion is a mating block or slot, to reduce the risk of disengagement between the second and fourth mating portions. In other embodiments, the first mating portion 31a and the third mating portion 21 only engage in abutment when mated, and the second mating portion and the fourth mating portion only engage in abutment when mated.

[0049] In a specific embodiment, the transfer mechanism is a second chain conveyor mechanism 4. The chain of the second chain conveyor mechanism 4 is provided with a chain connecting block 41. The carrier 3 is provided with a first engaging slot 32b. The second chain conveyor mechanism 4 is connected to the first engaging slot 32b via the chain connecting block 41 to drive the carrier 3 to slide on the track 1. The chain connecting block 41 forms a fourth engaging portion.

[0050] In a specific embodiment, Figure 2-Figure 4 As shown, the track 1 includes two tracks extending along the first direction, and the two tracks 1 are arranged at intervals, and the two ends of the carrier 3 are overlapped on the two tracks 1 and slidably connected thereto. The side of one track 1 close to the other track 1 is defined as the inner side, and the side of one track 1 away from the other track 1 is defined as the outer side. A chain conveying mechanism 2 extending along the first direction is provided on the inner side and / or the outer side of each track 1. Preferably, at least two chain conveying mechanisms 2 are provided on the inner side or the outer side of each track 1. Using multiple chain conveying mechanisms 2 to convey the carrier 3 in parallel can enhance the conveying power, increase the contact area between the chain conveying mechanism 2 and the carrier 3, and reduce the risk of the third matching portion 21 and the first matching portion 31a being disengaged; when the third matching portion 21 and the first matching portion 31a of one of the chain conveying mechanisms 2 are disengaged, the other chain conveying mechanisms 2 can continue to convey the carrier 3. Figure 2In the embodiment, two chain conveying mechanisms 2 extending along a first direction are provided on the outer side of each track 1. Figure 3 In the embodiment, a chain conveying mechanism 2 extending along a first direction is respectively provided on the inner side and the outer side of each track 1 . Figure 4 In the embodiment, two chain conveying mechanisms 2 extending along a first direction are provided on the inner side of each track 1 .

[0051] In a specific embodiment, Figure 5 As shown, the carrier 3 includes a first load-bearing beam 31; a plurality of product load-bearing parts 33 are suspended at intervals in the middle of the first load-bearing beam 31; a first matching part 31a is provided on one end or both ends of the first load-bearing beam 31 for matching and connecting with the third matching part 21 on the chain conveyor mechanism 2; guide rail slots 31b for clamping the guide rail 1 are also provided at both ends of the first load-bearing beam 31 to reduce the risk of the carrier 3 detaching from the guide rail 1; a gate-shaped bracket 32 is fixedly connected to the first load-bearing beam 31, and a first slot 32b is provided on the top beam of the gate-shaped bracket 32 for matching and connecting with the fourth matching part on the transfer mechanism, or the middle part 32a of the top beam of the gate-shaped bracket 32 is matched and connected with the fourth matching part.

[0052] In a specific embodiment, a groove is provided in the middle of the track 1 , and sliders that cooperate with the groove of the track 1 are provided at both ends of the vehicle 3 to prevent the vehicle 3 from derailing from the track 1 .

[0053] In a specific embodiment, a chain guide is provided directly below the chain conveyor mechanism 2. The chain guide supports the chain located below the chain conveyor mechanism 2. More specifically, the chain guide contacts the third mating portion 21 to prevent the chain conveyor mechanism 2 from sagging excessively, which could cause the chain and carrier to become disengaged. Preferably, the chain guide is a concave plastic guide. The chain guide limits the chain and prevents deviations in the sprocket installation at both ends of the chain conveyor mechanism 2, which could cause the chain to shift. Plastic chain guides are more wear-resistant, and the chain slides easily on them with less resistance.

[0054] In a specific embodiment, not shown in the figure, the third matching portion 21 is a hook, and the third matching portion 21 can hook the first load-bearing beam 31 to drive the carrier 3 to slide on the track 1; and / or, the fourth matching portion is a hook, and the fourth matching portion can hook the top beam of the door-shaped bracket 32 to drive the carrier 3 to slide on the track 1.

[0055] This embodiment also provides a cell manufacturing device, including the aforementioned carrier conveying device. The cell manufacturing device can be a line formed by one or more of a texturing device, an alkaline polishing device, an electroplating device, an etching device, and a cleaning device. For example, the cell manufacturing device is an electroplating device, the track 1 is conductive, for example, the track 1 is a copper rail, and the carrier 3 is conductive to direct current from the electroplating power supply to the cell in the carrier 3.

[0056] Example 2

[0057] like Figure 6-Figure 7 As shown, the difference from Example 1 is that the transfer mechanism includes a linear module 5, a module connection block 51 is provided on the driving end of the linear module 5, and a first slot 32b is provided on the carrier 3. The linear module 5 is connected to the first slot 32b through the module connection block 51 to drive the carrier 3 to slide on the track 1. The module connection block 51 forms a fourth matching portion. Figure 6 As shown, in the second preset position, the third matching portion 21 of the upstream chain conveyor mechanism 2 is disconnected from the first matching portion 31a, and the module connecting block 51 is connected to the first slot 32b, so that the linear module 5 can drive the carrier 3 to move. Figure 7 As shown, at the third preset position, the module connection block 51 is disconnected from the first latching slot 32b, and the third mating portion 21 of the downstream chain conveyor mechanism 2 is mated with the first mating portion 31a, enabling the downstream chain conveyor mechanism 2 to drive the carrier 3 to move. The module connection block 51 reciprocates between the second and third preset positions to continuously push the carrier from the second preset position to the third preset position. To prevent interference, the module connection block 51 is arbitrarily mounted on the slider of the linear module 5, for example, by a cylinder or linear motor.
