A battery cell handling mechanism and adhesive application device

Abstract

This application provides a battery cell handling mechanism and an adhesive application device. The battery cell handling mechanism includes a drive unit and two parallel, spaced-apart support rods, each rod being mounted on the drive end of the drive unit. Each support rod has a support bar that protrudes upwards from its top surface. The width of the support bar is less than the distance between adjacent rows of adhesive dots on the battery cell. Grooves are spaced along the length of one or both sides of the support bar. Each support bar is configured to collectively support at least one battery cell. The drive unit drives the support rods to synchronously lift, lower, and translate. Because of the support bars on the support rods, the rods can lift the battery cell using the support bars. The support bars support the non-adhesive application area on the battery cell located between adjacent rows of adhesive dots. Furthermore, because several grooves are spaced apart on one or both sides of the support bars, even if the support bars slightly shift while lifting the battery cell, the grooves can avoid the adhesive dots, thereby reducing the risk of adhesive rubbing against the support bars.

Description

Technical Field

[0001] This application relates to the field of photovoltaic module production equipment, specifically a cell handling mechanism and a coating device. Background Technology

[0002] For gridless solar cells, one stringing process involves first applying adhesive dots to designated locations on the solar cell using a solar cell adhesive applicator, and then stringing the solder ribbons to the solar cell.

[0003] During the adhesive application process, solar cells with adhesive dots on their lower surface need to be moved from one workstation to another. When there is limited space above, making it inconvenient to pick up the solar cells from above, they can only be lifted from below before being moved. However, the adhesive dots on the lower surface of the solar cells are dense, and they are easily scratched and damaged during handling. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a battery cell handling mechanism, the detailed technical solution of which is as follows:

[0005] A battery cell handling mechanism is used to handle battery cells whose lower surface has been coated with adhesive. The lower surface of the battery cell has a number of adhesive application points, and each row of adhesive application points includes multiple spaced adhesive dots.

[0006] The cell handling mechanism includes a drive unit and two parallel, spaced-apart support rods, with each support rod mounted on the drive end of the drive unit.

[0007] Each support rod has at least one support bar. The support bar protrudes upward from the top surface of the support rod and extends along the length of the support rod. The width of the support bar is smaller than the spacing between two adjacent rows of adhesive dots on the battery cell. Furthermore, a number of grooves for avoiding adhesive dots are provided at intervals along the length of one or both sides of the support bar.

[0008] Each support bar is configured to collectively support at least one solar cell;

[0009] The drive unit is used to drive each support rod to rise, fall, and translate synchronously.

[0010] The battery cell handling mechanism provided in this application uses a drive unit to drive a support rod to rise, fall, and translate, thereby lifting the battery cell from below for handling. Because the support rod is equipped with support bars, and the width of the support bars is smaller than the distance between adjacent rows of adhesive dots on the battery cell, the support rod can lift the battery cell using the support bars. The support bars support the non-adhesive area on the battery cell located between adjacent rows of adhesive dots. Furthermore, because several grooves are spaced along the length of one or both sides of the support bars to avoid the adhesive dots, even if the support bars slightly shift when lifting the battery cell, the grooves can still avoid the adhesive dots, thus reducing the risk of adhesive rubbing against the support bars.

[0011] In some embodiments, the support bar is provided with a plurality of adsorption holes for adsorbing battery cells at intervals along its length; the support rod is provided with an air passage communicating with the adsorption holes, and the air passage is connected to an external vacuum generator.

[0012] The support bar uses its suction holes to position and hold the battery cells, preventing slippage during transport. A vacuum generator evacuates air from the support rod, creating an adsorption force in the suction holes to hold the battery cells in place.

[0013] In some embodiments, the adsorption holes and grooves are offset along the length of the support rod.

[0014] The adsorption holes and grooves are staggered, so that the adsorption holes and grooves do not interfere with each other, and both have a sufficiently large installation space.

[0015] In some embodiments, each support rod has at least two support bars spaced apart along the length of the support rod; the support rod is provided with at least two air passages spaced apart along the length of the support rod and corresponding one-to-one with the support bars, and each air passage is connected to the adsorption hole on the corresponding support bar.

[0016] Since each support rod has at least two support bars spaced apart along its length, and each support bar has an independent air passage, at least two independent cell adsorption positions can be formed on the support rod. This allows the cell transport mechanism of this application to achieve transport and shuttle between at least three workstations. For example, in the case where a support rod has two cell adsorption positions, while one cell adsorption position is transporting a cell from the first workstation to the second workstation, the other cell adsorption position can transport a cell from the second workstation to the third workstation.

[0017] In some embodiments, the middle part of the support rod is mounted on the drive end of the drive unit; support bars are provided on both sides of the support rod located at the drive end of the drive unit, and / or a support bar is provided in the middle part of the support rod.

[0018] The middle part of the support rod is installed on the drive end of the drive unit, and support bars are provided on both sides of the support rod located on the drive end of the drive unit. This can improve the stability of the support rod, eliminate the deflection torque, and prevent the support rod from tilting.

[0019] In some embodiments, one end of the support rod is mounted on the drive end of the drive unit.

[0020] One end of the support rod is mounted on the drive end of the drive unit. This design allows the support rod to suspend in the air without any supporting structure underneath, enabling it to move freely between different workstations and improving handling flexibility.

[0021] In some embodiments, the drive unit includes a translation drive assembly and a lifting drive assembly, wherein: the lifting drive assembly is connected to the drive end of the translation drive assembly, and each support rod is mounted on the drive end of the lifting drive assembly; the lifting drive assembly is used to drive each support rod to move up and down synchronously, and the translation drive assembly is used to drive each support rod to move horizontally synchronously.

[0022] By combining the translation drive assembly and the lifting drive assembly, the drive unit can flexibly drive the support rod to move horizontally and vertically, thereby improving the flexibility of the support rod in handling the battery cells.

[0023] This application also provides a coating device, including a first coating mechanism, a flipping mechanism, a straightening mechanism, a second coating mechanism, and the battery cell transport mechanism described in any one of the above, wherein:

[0024] The first gluing mechanism, the flipping mechanism, the straightening mechanism, and the second gluing mechanism are arranged sequentially along the first direction;

[0025] The first adhesive application mechanism is configured to apply adhesive to the first surface of the solar cell;

[0026] The flipping mechanism is used to receive the battery cells after the first surface coating has been completed, and flips the battery cells 180° and places them on the straightening table of the straightening mechanism.

[0027] The alignment mechanism is configured to correct the position of the battery cells provided by the flipping mechanism;

[0028] The cell transport mechanism is configured to lift the cells on the straightening table of the straightening mechanism, move the cells in a first direction to above the glue application table of the second glue application mechanism, and lower the cells onto the glue application table of the second glue application mechanism.

[0029] With the cooperation of the first adhesive application mechanism, the flipping mechanism, the straightening mechanism, the second adhesive application mechanism, and the cell transport mechanism, the adhesive application device provided in this application can continuously apply adhesive to both surfaces of the cell, thereby improving adhesive application efficiency.

[0030] In some embodiments, the leveling platform of the leveling mechanism is provided with a first clearance groove that corresponds one-to-one with the support rod of the battery cell transport mechanism.

[0031] By setting a first clearance groove on the leveling table that corresponds one-to-one with the support rod of the battery cell transport mechanism, when the drive unit drives the support rod to descend toward the leveling table, the support rod sinks into the first clearance groove of the leveling table, so that the battery cell on the support rod is blocked by the leveling table and falls onto the surface of the leveling table.

[0032] In some embodiments, the glue application table of the second glue application mechanism is provided with a second clearance groove that corresponds one-to-one with the support rod of the battery cell transport mechanism.

[0033] By providing a second clearance groove on the glue application table of the second glue application mechanism that corresponds one-to-one with the support rod of the battery cell transport mechanism, when the drive unit drives the support rod to descend toward the glue application table of the second glue application mechanism, the support rod sinks into the second clearance groove of the glue application table, thereby causing the battery cell on the support rod to be blocked by the glue application table and fall onto the glue application table.

[0053] To make the above-mentioned objects, 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. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] As described in the background section, during the adhesive application process, it is necessary to move the solar cells with adhesive dots on their lower surface from one workstation to another. When the space above is limited and it is inconvenient to pick up the solar cells from above, the solar cells can only be lifted from below before being moved. However, the adhesive dots on the solar cells are dense, and they are easily scratched during handling, causing damage to the adhesive dots.

[0055] Therefore, this application provides a battery cell handling mechanism for handling... Figure 10 The battery cell 100 shown has a lower surface coated with adhesive. The lower surface of the battery cell 100 has a number of adhesive dots, and each row of adhesive dots includes multiple spaced adhesive dots 101.

[0056] like Figures 1 to 7 As shown, the battery cell handling mechanism 10 provided in this application includes a drive unit 1 and two parallel and spaced support rods 2, with each support rod 2 mounted together at the drive end of the drive unit 1.

[0057] Each support rod 2 has at least one support bar 3. The support bar 3 protrudes upward from the top surface of the support rod 2 and extends along the length of the support rod 2. The width of the support bar 3 is less than the distance between two adjacent rows of adhesive dots 101 on the battery cell 100. Furthermore, a number of grooves 4 for avoiding adhesive dots are provided at intervals along the length direction on one or both sides of the support bar 3.

[0058] Each support bar 3 is configured to jointly support at least one battery cell 100.

[0059] The drive unit 1 is used to drive each support rod 2 to rise, fall and move synchronously.

[0060] The battery cell handling mechanism 10 provided in this application drives the support rod 2 to rise, fall, and move horizontally via the drive unit 1, so as to lift the battery cell 100 from below and carry it out.

[0061] Since the support rod 2 is provided with a support bar 3, and the width of the support bar 3 is smaller than the distance between two adjacent rows of adhesive dots 101 on the battery cell 100, the support rod 2 can support the battery cell 100 through the support bar 3. The support bar 3 supports the non-adhesive area on the battery cell 100 located between two adjacent rows of adhesive dots 101.

[0062] At the same time, such as Figure 6 and Figure 7 As shown, since a number of grooves 4 for avoiding adhesive points are provided at intervals along the length direction on one or both sides of the support bar 3, even if the support bar 3 is slightly offset when supporting the battery cell 100, the grooves 4 can avoid the adhesive points 101, thereby reducing the risk of the support bar 3 rubbing against the adhesive.

[0063] The specific width of the support strip 3 and the specific dimensions of the groove 4 can be adaptively set according to the spacing between two adjacent rows of adhesive dots 101 on the battery cell 100. The shape of the groove can be set arbitrarily, such as semi-circle, triangle, rectangle, trapezoid, etc.

[0064] like Figure 2 and Figure 3 As shown, the support bar 3 has several adsorption holes 5 spaced along its length for adsorbing battery cells. The support rod 2 has an air passage 6 that communicates with the adsorption holes 5 and is connected to an external vacuum generator.

[0065] After the support bar 3 supports the battery cell 100, the support bar 3 adsorbs the battery cell 100 through the adsorption hole 5 on it, so as to prevent the battery cell 100 from slipping during transportation.

[0066] like Figure 3 As shown, optionally, the adsorption hole 5 and the groove 4 are offset along the length of the support rod 2. This ensures that the adsorption hole 5 and the groove 4 do not interfere with each other, and both have sufficiently large installation space.

[0067] Optionally, each support rod 2 has at least two support bars 3 spaced apart along the length of the support rod 2. In addition, the support rod 2 is provided with at least two air passages 6 spaced apart along the length of the support rod 2 and corresponding one-to-one with the support bars 3, and each air passage 6 is connected to the adsorption hole 5 on the corresponding support bar 3.

[0068] Since each support rod 2 is provided with at least two support bars 3 at intervals along its length, and each support bar 3 has an independent air passage 6, at least two independent battery cell adsorption positions can be formed on the support rod 2, which ultimately enables the battery cell handling mechanism of this application to shuttle between multiple workstations arranged at intervals along the length of the support rod 2.

[0069] For example, Figures 1 to 8In the embodiment shown, each support rod 2 has two support bars 3 spaced apart along the length of the support rod 2, thereby forming two independent battery cell adsorption positions on the support rod 2, namely battery cell adsorption position C and battery cell adsorption position D.

[0070] This cell handling mechanism can shuttle between a first processing station, a second processing station, and a third processing station, wherein the first, second, and third processing stations are spaced apart along the length of the support rod 2. The optional handling process of the cell handling mechanism is as follows:

[0071] The drive unit 1 drives the two support rods 2 to move along the length of the support rods 2 to the first position, so that the battery cell adsorption position C moves to below a number of battery cells (e.g., 3) located in the first processing station, and the battery cell adsorption position D moves to below a number of battery cells (e.g., 3) located in the second processing station.

[0072] Subsequently, the drive unit 1 drives the two support rods 2 to rise, so that the battery cell adsorption positions C and D respectively support and adsorb several battery cells located above them.

[0073] Next, the drive unit 1 drives the two support rods 2 to move horizontally along the length of the support rods 2 to the second position, the battery cell adsorption position C moves above the second processing station, and the battery cell adsorption position D moves above the third processing station.

[0074] Finally, the drive unit 1 drives the two support rods 2 to descend, the battery cell adsorption position C lowers the battery cell on it to the second processing station, and the battery cell adsorption position D lowers the battery cell on it to the third processing station.

[0075] Of course, in other embodiments, each support rod 2 may also be provided with three or more support bars along its length, thereby enabling the support rod 2 to shuttle between a greater number of workstations spaced apart along its length.

[0076] like Figure 1 As shown, in one embodiment, the middle part of the support rod 2 is mounted on the driving end of the driving part 1, and support bars 3 are provided on both sides of the support rod 2 located at the driving end of the driving part 1.

[0077] The middle part of the support rod 2 is installed on the drive end of the drive unit 1, and support bars 3 are provided on both sides of the support rod 2 located at the drive end of the drive unit 1. This can ensure the stability of the support rod 2, eliminate the deflection torque, and prevent the support rod 2 from tilting during transportation. This is especially suitable for cases where the support rod 2 is long.

[0078] Of course, support bars 3 can also be provided in the middle of the support rod 2, that is, support bars 3 can be provided on both sides of the drive end of the drive unit 1 and in the middle of the support rod 2. Alternatively, support bars can be provided only in the middle of the support rod 2. This arrangement can also ensure the stability of the support rod 2 and prevent the support rod 2 from tilting during transportation.

[0079] In another embodiment, one end of the support rod 2 is mounted on the drive end of the drive unit 1, which is particularly suitable for cases where the support rod 2 is relatively short. This arrangement allows the support rod 2 to be suspended in the air, with no supporting structure underneath, thereby enabling the support rod 2 to move more freely between different workstations and improving handling flexibility.

[0080] like Figure 1 As shown, optionally, the drive unit 1 includes a translation drive assembly 11 and a lifting drive assembly 12, wherein the lifting drive assembly 12 is connected to the drive end of the translation drive assembly 11, and each support rod 2 is mounted on the drive end of the lifting drive assembly 12. The lifting drive assembly 12 is used to drive each support rod 2 to move up and down synchronously, and the translation drive assembly 11 is used to drive each support rod 2 to move horizontally synchronously.

[0081] By cooperating with the translation drive assembly 11 and the lifting drive assembly 12, the drive unit 1 can drive the support rod 2 to both translate and lift, thereby improving the flexibility of the support rod 2 in handling the battery cells.

[0082] The translation drive assembly 11 and the lifting drive assembly 12 can each adopt existing linear drive mechanisms of various structures. For example, a screw drive mechanism consisting of a motor, a lead screw, and a nut, or a timing belt drive mechanism consisting of a motor, a timing pulley, and a timing belt.

[0083] This application also provides a glue application device. For example... Figure 9 As shown, the adhesive application device includes a first adhesive application mechanism 20, a flipping mechanism 30, a straightening mechanism 40, a second adhesive application mechanism 50, and a battery cell transport mechanism 10 provided in any of the above embodiments, wherein:

[0084] The first glue application mechanism 20, the flipping mechanism 30, the straightening mechanism 40, and the second glue application mechanism 50 are arranged sequentially along the first direction (such as the X direction).

[0085] The first adhesive application mechanism 20 is configured to apply adhesive to the first surface of the solar cell.

[0086] The flipping mechanism 30 is used to receive the battery cells after the first surface coating is completed, and flips the battery cells 180° and places them on the straightening table of the straightening mechanism 40.

[0087] The alignment mechanism 40 is configured to correct the position of the battery cells provided by the flipping mechanism 30.

[0088] The cell transport mechanism 10 is configured to lift the cells on the straightening table of the straightening mechanism 40, move the cells in a first direction to above the glue application table of the second glue application mechanism 50, and lower the cells onto the glue application table of the second glue application mechanism 50.

[0089] With the cooperation of the first adhesive application mechanism 20, the flipping mechanism 30, the straightening mechanism 40, the second adhesive application mechanism 50 and the cell transport mechanism 10, the adhesive application device provided in this application can continuously apply adhesive to both surfaces of the cell, thereby improving the adhesive application efficiency.

[0090] Both the first adhesive application mechanism 20 and the second adhesive application mechanism 50 can be any existing adhesive application mechanism capable of applying adhesive dots to the battery cell, such as screen printing machines, dispensing machines, etc.

[0091] The flipping mechanism 30 can employ various existing mechanisms capable of flipping solar cells. For example, the flipping mechanism 30 includes a first turntable, a second turntable, and a driving component. The first turntable is located on the first side of the output mechanism of the first coating mechanism 20, and the second turntable is located on the second side of the output mechanism of the first coating mechanism 20. The first turntable has a first slot, and the second turntable has a second slot corresponding to the first slot. The driving component drives the first and second turntables to rotate synchronously, thereby switching the first and second slots between the infeed position and the outfeed position. When the first and second slots rotate to the infeed position, they align with the conveying surface of the output mechanism, and the first and second sides of the solar cell with the first surface coated on the output mechanism are inserted into the first and second slots, respectively. When the first and second slots rotate 180° to reach the outfeed position, the flipped solar cell falls onto the straightening mechanism 40 and is disengaged from the first and second slots by the output mechanism. Alternatively, the flipping mechanism 30 includes two cantilever arms and a rotary motor that drives the cantilever arms to rotate vertically. The cantilever arms are provided with suction holes or suction cups. When the cantilever arms turn to the first gluing mechanism 20, they pick up the battery cells from the first gluing mechanism 20. When they turn to the straightening mechanism 40, they place the battery cells onto the straightening mechanism 40.

[0092] The straightening mechanism 40 can be any existing straightening mechanism capable of straightening the solar cells. For example, the straightening mechanism 40 includes a straightening table and a first straightening wheel and a second straightening wheel arranged opposite each other on both sides of the straightening table. When the flipping mechanism 30 flips the solar cell onto the straightening table of the straightening mechanism 40, the first straightening wheel and the second straightening wheel move toward the straightening table, thereby correcting the position of the two opposite sides of the solar cell.

[0093] Optionally, the leveling platform of the leveling mechanism 40 is provided with a first clearance groove that corresponds one-to-one with the support rod 2 of the battery cell transport mechanism 10.

[0094] The optional working process of the battery cell handling mechanism 10 is as follows:

[0095] The drive unit 1 drives the support rod 2 to sink into the first clearance groove. Then the flipping mechanism 30 places the battery cell onto the straightening mechanism 40. After straightening is completed, the drive unit 1 drives the support rod 2 to rise. The support rod 2 can then attract the battery cell on the straightening table and lift the battery cell upward.

[0096] Optionally, the glue application table of the second glue application mechanism is provided with a second clearance groove that corresponds one-to-one with the support rod 2 of the battery cell transport mechanism 10.

[0097] After the support rod 2 lifts the battery cells on the leveling table upwards.

[0098] The drive unit 1 drives the support rod 2 to move horizontally toward the glue application table of the second glue application mechanism until the battery cell on the support rod 2 moves above the glue application table of the second glue application mechanism 50.

[0099] Subsequently, the drive unit 1 drives the support rod 2 to descend, causing the support rod 2 to sink into the second clearance groove of the coating table. The battery cells on the support rod 2 are blocked by the second coating table and fall onto the second coating table.

The scope of protection claimed in this application is defined by the claims, not by the above descriptions in the embodiments. Without contradiction, some optional components in one embodiment can also be used in another embodiment, and some preferred structures of the same component in one embodiment are also applicable to another embodiment. Furthermore, there may be slight differences in the wording of the names of certain components in different embodiments; these slight differences will not affect the understanding of the technical solution of the present invention by those skilled in the art.
