Description

Technical Field

[0001] This application belongs to the field of photovoltaic cell production equipment technology, and in particular relates to a cell string flipping mechanism. Background Technology

[0002] Back-contact solar cells are a type of solar cell where both the positive and negative electrodes are located on the back side, with no electrode grid lines obstructing the front, unlike traditional solar cells which have one electrode on each side. Therefore, the solder ribbons of a back-contact solar cell are arranged in an alternating pattern on the back of each cell.

[0003] In the production process of photovoltaic cell modules, after the back contact cell strings are welded, they usually need to be transported to the printing area for adhesive application. However, in some back contact cell welding processes, the solder ribbon is laid on the lower surface of the cell array. Therefore, before sending the cell strings to the printing equipment, the cell strings need to be flipped over to facilitate adhesive application. This requires the design of a cell string flipping mechanism to flip the cell strings before adhesive application. Utility Model Content

[0004] The purpose of this application is to provide a battery string flipping mechanism to solve the above-mentioned problems existing in the prior art.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application proposes a battery string flipping mechanism, which includes a substrate, a first driving assembly, a rotating assembly, and a picking assembly, wherein:

[0007] The fixed end of the first drive component is mounted on the substrate, the drive end of the first drive component is connected to the rotating component, the rotating component is hinged on the substrate, the pickup component is disposed on the rotating component, and the pickup component is configured to pick up or release the battery string to be flipped.

[0008] The first driving component is configured to drive the rotating component to rotate to a position where the suction end of the picking component is facing upward, so as to pick up the back of each battery cell of the battery string to be flipped.

[0009] The first drive component drives the rotating component to rotate 180° so that the battery string picked up by the pickup component is flipped over.

[0010] The battery string flipping mechanism proposed in this application first drives the rotating component to rotate to a position where the adsorption end of the picking component faces upward. Then, the picking component picks up the back of each battery cell in the battery string to be flipped. The first driving component then drives the rotating component to rotate 180°, thereby flipping the battery string picked up by the picking component so that the side of the battery string with the solder strip faces upward, which facilitates the subsequent printing of adhesive on the battery string and improves the printing efficiency of the battery string.

[0011] Optionally, the rotating assembly includes two rotating shafts, two rotating arms, and a support beam, wherein:

[0012] Two rotating shafts are spaced apart along a first direction and rotatably mounted on a substrate. The driving end of the first driving assembly is connected to at least one rotating shaft, and the first driving assembly is configured to drive the connected rotating shaft to rotate.

[0013] Each rotating arm corresponds to a rotating shaft. The first ends of the two rotating arms are fixedly connected to the corresponding rotating shafts, and the second ends of the two rotating arms are fixedly connected to the two ends of the support beam along the first direction. The pickup assembly is installed on the support beam and extends along the first direction.

[0014] By fixing the two ends of the two rotating arms to the corresponding rotating shafts and the two ends of the support beam respectively, stable and reliable support for the support beam is achieved, providing a rotating component with a robust structure and stable and reliable rotational action.

[0015] Optionally, the first drive assembly includes a first motor and a coupling, wherein:

[0016] The fixed end of the first motor is fixedly mounted on the base plate. The rotating shaft of the first motor is connected to one of the rotating shafts via a coupling. The first motor drives the connected rotating shaft to rotate, thereby driving the two rotating arms to rotate.

[0017] By cooperating with the first motor and the coupling, one of the rotating shafts is driven to rotate, which in turn drives the two rotating arms to rotate. This provides a first drive component with a simple structure and high driving efficiency. At the same time, the flexibility of the coupling absorbs and mitigates vibration and impact during the driving process, improving the smoothness of the rotating component's rotation.

[0018] Optionally, the battery string flipping mechanism also includes a base and a second drive assembly, wherein:

[0019] The substrate is vertically mounted on the base, the fixed end of the second drive assembly is mounted on the base, the drive end of the second drive assembly is connected to the substrate, and the second drive assembly is configured to drive the substrate to move up and down.

[0020] The first drive component drives the rotating component to rotate 180° so that the battery string picked up by the pickup component is flipped over. Then, the second drive component drives the substrate and the pickup component to descend so as to release the flipped battery string onto the printing equipment.

[0021] The second drive component and the base work together to lift the picking component, which makes it easier for the battery string flipping mechanism to quickly pick up the battery cells and connect them to the subsequent printing equipment, thus improving the printing efficiency of the battery string.

[0022] Optionally, the second drive assembly includes a second motor, a first pulley, a second pulley, a transmission belt, a lead screw, and a lead screw nut, wherein:

[0023] The lead screw is rotatable along its own axis and extended vertically on the base. The lead screw nut is rotatably sleeved on the lead screw and fixedly connected to the base plate.

[0024] The fixed end of the second motor is mounted on the base. The rotating shaft of the second motor is coaxially connected to the first pulley. The second pulley is coaxially connected to the lead screw. The transmission belt is sleeved on the first pulley and the second pulley.

[0025] The second motor is configured to drive the first pulley to rotate, thereby driving the second pulley to rotate via the transmission belt, which in turn drives the lead screw to rotate along its own axis, thereby driving the base plate to reciprocate in the vertical direction via the lead screw nut.

[0026] The first pulley is driven to rotate by the second motor, which in turn drives the second pulley to rotate via the transmission belt. The second pulley drives the lead screw to rotate, and the lead screw and lead screw nut work together to lift the base plate, thereby lifting the pickup assembly. This provides a second drive assembly with a compact structure, high drive efficiency, and high drive precision.

[0027] Optionally, the pickup assembly includes several sets of adsorption elements, which are spaced apart on the support beam along a first direction, and each set of adsorption elements is configured to adsorb or release a battery cell.

[0028] By setting up several sets of adsorption elements, each adsorbing one battery cell, a stable and reliable pick-up component is provided; moreover, the adsorption elements adsorb the battery cells, and the connection between the adsorption elements and the battery cells is flexible. When the battery cells are leveled, the adsorption elements can adapt to the deformation of the battery cells, avoiding damage to the battery cells during the shaping process.

[0029] Optionally, the pickup assembly also includes a third driving assembly and several sets of limiting assemblies, each set of limiting assemblies corresponding to a set of adsorption elements, wherein:

[0030] The adsorption element is mounted on the support beam in a height-adjustable manner. The third drive assembly is mounted on the support beam. The drive end of the third drive assembly is connected to several sets of adsorption elements. Each set of adsorption elements is configured to hold the middle part of the battery cell. The third drive assembly is configured to drive several sets of adsorption elements to move up and down synchronously.

[0031] The limiting component includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are fixed on the support beam. The first limiting member and the second limiting member are respectively arranged on both sides of a corresponding set of adsorption members. The limiting surfaces of the first limiting member and the second limiting member are at the same height.

[0032] The third driving component drives several sets of adsorption components to hold several battery cells, so that the two sides of the battery cells abut against the limiting surfaces of the first limiting component and the second limiting component.

[0033] The third drive component drives several sets of adsorption elements to move closer to the support beam, so that the middle part of the battery cell held by the adsorption elements moves toward the support beam.

[0034] By setting a limiting component on the pickup mechanism, after the adsorption element adsorbs the middle part of the corresponding battery cell, the third drive component drives the adsorption element and the adsorbed battery cell to rise. During the rising process of the battery cell, the two ends of the battery cell in the first direction abut against the limiting surfaces of the first and second limiting elements. The adsorption element drives the battery cell to continue to move upward, causing the middle part of the adsorbed battery cell to move upward, thus leveling the battery cell and ensuring the uniformity of subsequent adhesive printing, thereby improving the processing quality of the battery string. At the same time, the limiting component is integrated into the pickup component. During the process of picking up the battery string and transferring it to the adhesive printing equipment, the pickup component levels the picked-up battery string, eliminating the need for a separate leveling station, simplifying the process flow, improving production efficiency, and meeting the requirements of fast-paced processing.

[0035] Optionally, the third drive assembly includes a third drive member, a slider, and at least one transmission assembly, wherein:

[0036] The fixed end of the third driving member is mounted on the support beam, and the sliding member is slidably mounted on the support beam in the first direction. The driving end of the third driving member is connected to the sliding member, and the third driving member is configured to drive the sliding member to slide in the first direction.

[0037] The first end of the transmission assembly is connected to the sliding member, and the second end of the transmission assembly is connected to several sets of adsorption members. The transmission assembly is configured to drive each adsorption member to rise and fall synchronously while the sliding member slides back and forth along the first direction.

[0038] The sliding component is driven to reciprocate along the first direction by the third driving component, and then the transmission component drives the various adsorption components to rise and fall synchronously. This realizes the synchronous rising and falling of all adsorption components by using one driving component, and provides a third driving component with simple structure, compact layout and reasonable design.

[0039] Optionally, the transmission assembly includes several inclined track grooves and several lifting rods, each lifting rod corresponding to a set of adsorption components, wherein:

[0040] Several inclined track grooves are spaced apart on the sliding member along the first direction. Each track groove corresponds to a lifting rod. The first end of the lifting rod is provided with a limit wheel, which is inserted into the corresponding track groove. The second end of the lifting rod is fixedly connected to the adsorption member.

[0041] When the limiting wheel is located at the end of the track groove away from the support beam, the adsorption end of the adsorption component is flush with the limiting surfaces of the first and second limiting components; when the limiting wheel is located at the end of the track groove close to the support beam, there is a height difference between the adsorption end of the adsorption component and the limiting surfaces of the first and second limiting components.

[0042] By setting several inclined track grooves at intervals along the first direction on the sliding member, and inserting the limiting wheel connected to the second end of the lifting rod into the track groove, the track groove slides horizontally with the sliding member, driving the limiting wheel to move synchronously in the track groove, and then synchronously driving the lifting rod to rise and fall, so as to realize the synchronous lifting and falling of the adsorption member, providing a transmission component with precise guidance control, stable and reliable operation and long service life.

[0043] Optionally, the battery string flipping mechanism also includes an air blowing device and at least one air blowing pipe, the air blowing device being connected to the air blowing pipe and the air blowing device being configured to supply gas into the air blowing pipe.

[0044] The air blowing pipe is fixedly installed on the support beam and extends along the first direction. The air blowing pipe has multiple air blowing holes arranged at intervals along the first direction, and the air blowing holes are set towards the battery cell that is picked up by the pickup component.

[0045] By setting up an air blowing assembly, rapid cooling of the battery cells is achieved during leveling, thereby fixing the shape of the battery cells and reducing the probability of deformation after leveling. At the same time, by setting up an air blowing pipe and air blowing device, air is blown onto the battery cells picked up by each picking assembly through multiple air blowing holes on the air blowing pipe, providing an air blowing assembly with a simple structure and good cooling effect.

[0062] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] Back-contact solar cell strings have both positive and negative electrodes on the back side of the cells, with no electrode grid lines obstructing the front, unlike traditional solar cells which have one electrode on each side. Therefore, the solder ribbons in back-contact solar cell strings are staggered on the back of each cell. In the production of photovoltaic modules, after welding, back-contact solar cell strings typically need to be transported to the printing area for adhesive application. However, in some back-contact cell welding processes, the solder ribbons are laid on the lower surface of the cell assembly. Therefore, before sending the cell string to the printing equipment, it needs to be flipped over to facilitate adhesive application. This necessitates the design of a cell string flipping mechanism to flip the cell string before adhesive application.

[0066] The battery string flipping mechanism proposed in this application first drives the rotating component 30 to rotate to a position where the adsorption end of the picking component 40 faces upward. Then, the picking component 40 picks up the back of each battery cell 11 of the battery string to be flipped. Then, the first driving component 20 drives the rotating component 30 to rotate 180°, thereby flipping the battery string picked up by the picking component 40 so that the side of the battery string with the solder strip faces upward, which facilitates the subsequent printing of adhesive on the battery string and improves the printing efficiency of the battery string.

[0074] Through the cooperation of the second drive component 50 and the base 12, the lifting and lowering of the picking component 40 is realized, thereby enabling the battery string flipping mechanism to quickly pick up the battery cell 11 and connect it to the subsequent printing equipment, thus improving the printing efficiency of the battery string.

[0079] Specifically, each set of adsorption components 41 includes a support base 410 and several suction cups 411. The support base 410 is fixedly installed on the support beam 411, and the support base 410 is along the second direction ( Figure 1 Extending in the Y direction, several suction cups 411 are spaced apart on the support base 410 along the second direction to ensure the stability of the battery string adsorption.

[0080] Specifically, each set of adsorption components 41 includes four suction cups 411.

[0081] By setting up several sets of adsorption elements 41, a pickup component 40 is provided that uses adsorption to pick up the battery cell 11.

The component 431 is fixed on the support beam 33.

The third driving component 42 drives the several sets of adsorption components 41 to move closer to the support beam 33, so that the middle part of the battery cells 11 attracted by the adsorption component 41 moves toward the support beam 33.

[0083] By setting a limiting component 43 on the picking mechanism, after the adsorption member 41 adsorbs the middle part of the corresponding battery cell 11, the third driving component 42 drives the adsorption member 41 and the adsorbed battery cell 11 to rise.

[0092] In one embodiment, the battery string flipping mechanism further includes an air blowing device and at least one air blowing pipe 330.

[0095] Please see Figure 1 , Figure 6 and Figure 7 As shown, the general working process of the battery string flipping mechanism proposed in this embodiment when applied to the printing equipment 70 is as follows:

[0096] S1, the conveying mechanism 60 picks up the battery string that has been welded on the transmission platform 61 of the welding equipment;

[0097] S2, the first driving component 20 drives the rotating component 30 to rotate to the position where the adsorption end of the picking component 40 faces upward, so that the picking component 40 can pick up the back of each battery cell 11 of the battery string on the transport mechanism 60.

[0098] S3, the first driving component 20 drives the rotating component 30 to rotate 180° so that the battery string picked up by the picking component 40 is flipped over;

[0099] S4, the picking component 40 places the flipped battery string on the printing table 71 of the printing equipment 70;

[0100] S5, the printing table 71 of the printing equipment 70 moves the received flipped battery string to the printing mechanism of the printing equipment 70 for printing.

[0101] The battery string flipping mechanism proposed in this embodiment has the following advantages:

[0102] 1) The battery string picked up by the pickup component 40 is flipped so that the side of the battery string with the solder strip is facing up, which facilitates the subsequent printing of adhesive on the battery string and improves the printing efficiency of the battery string.

[0103] 2) The rotating component 30 has a robust overall structure and operates stably and reliably.

[0104] 3) It enables online leveling of the held battery strings, thereby ensuring the uniformity of subsequent adhesive printing and improving the processing quality of the battery strings;

[0105] 4) The transmission component 422 enables simultaneous leveling of all the battery cells 11 of the adsorbed battery string, resulting in high leveling efficiency.

[0106] 5) The solar cell 11 is rapidly cooled while being leveled, which fixes the shape of the solar cell 11 and reduces the probability of deformation of the solar cell 11 after leveling.
