Technical Field

[0001] This invention belongs to the field of battery cell tape bonding technology, specifically a battery cell tape bonding device. Background Technology

[0002] After the battery cells are produced, they need to be processed through a cloth sheet and then tapeped to form a battery string before being sent to the next process for assembly.

[0003] In the prior art, when applying tape to the battery cells, a pneumatic device is used to first extract a piece of tape of equal length, and then a vision sensor is used to move it to the edge of the adjacent battery cell. The pneumatic device is then used to attach the tape to the edge of the adjacent battery cell to complete the connection of the adjacent battery cells.

[0004] However, in the aforementioned prior art, the equipment used for applying tape to battery cells often requires a large space for the track for the pneumatic equipment to move, and also requires design for the air path layout of the pneumatic equipment, resulting in a relatively complex structure that affects the efficiency of applying tape after the battery cells are arranged.

[0005] Therefore, the present invention provides a battery cell tape bonding device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a battery cell tape bonding device of the present invention, comprising:

[0008] The track is fixed to the base plate;

[0009] A tape application module fixed to one end of the track, and a battery string transport module fixed to the other end of the track;

[0010] A tape sheet platform that slides onto one side of the track;

[0011] A battery cell placement platform is slidably connected to the other side of the track;

[0013] Preferably, a plurality of tape adsorption modules are fixedly connected to the top of the tape sheet platform at equal intervals; a first translation module is slidably connected to the side of the tape sheet platform for driving the tape sheet platform to slide on the track; and a first lifting module is also provided at the bottom of the tape sheet platform for driving the tape sheet platform to slide up and down.

[0014] Preferably, the top of the battery cell placement platform is fixed with multiple battery cell adsorption modules arranged at equal intervals, and the side of the battery cell placement platform is slidably connected to a second translation module for driving the battery cell placement platform to slide on the track; the bottom of the battery cell placement platform is also provided with a second lifting module for driving the battery cell placement platform to slide up and down.

[0015] Preferably, the tape adsorption module includes a support rod; the support rod has a first air passage connection port; a first heating rod and a first temperature sensor are respectively passed through one end of the support rod; a plurality of first air intakes are equidistantly arranged on the surface of the support rod; the first air intakes are used to adsorb tape.

[0016] Preferably, the battery cell adsorption module includes a tray; the tray has a second air passage connection port; a second heating rod and a second temperature sensor are respectively passed through one end of the tray; a plurality of second air intakes are equidistantly arranged on the surface of the tray, and the second air intakes are used to adsorb battery cells.

[0017] Preferably, the width of the support rod is smaller than the spacing between adjacent trays, and the support rod is used to support the tape that passes between adjacent trays.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The battery cell tape bonding device of the present invention utilizes a tape-applying module to cut tape of equal length and attach it to a tape-applying platform. The tape-applying platform is then moved horizontally along a track to a position directly above a battery cell platform.

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 4 As shown in the figure, a battery cell tape bonding device according to an embodiment of the present invention includes:

[0031] Track 16 is fixed to the base plate 3;

[0032] The tape application module 1 is fixed to one end of the track 16, and the battery string transport module 4 is fixed to the other end of the track 16.

[0033] A tape sheet platform 5 is slidably connected to one side of track 16;

[0034] A battery cell placement platform 2 is slidably connected to the other side of track 16;

[0035] The battery string transport module 4 is used to transport battery cell strings with tape attached; the tape application module 1 is used to cut tape of equal length onto the tape application platform 5; the tape application platform 5 is used to support the tape segments as they move on the track 16; the battery cell application platform 2 is used to support multiple battery cells; the tape application platform 5 and the battery cell application platform 2 cooperate to apply the tape between adjacent battery cells.

[0036] When using the bonding device provided by the present invention, tape of equal length is cut using the tape application module 1 and attached to the tape cloth platform 5. The tape cloth platform 5 is then moved horizontally on the track 16 to be directly above the battery cell cloth platform 2. Subsequently, the tape cloth platform 5 is controlled to move downward to attach the tape to the battery cell supported on the surface of the battery cell cloth platform 2.

[0037] In this device, adjacent solar cells are pre-supported on the solar cell placement platform 2, with gaps reserved between them for the tape placement platform 5 to pass through. When the tape placement platform 5 and the solar cell placement platform 2 intersect, the tape can be attached to the adjacent solar cells, thus completing the tape application operation for the adjacent solar cells. Compared with the prior art, this bonding device has a simple structure and high completion rate, which can improve the tape application efficiency of the solar cells.

[0038] like Figures 1 to 4 As shown, a plurality of tape adsorption modules 6 are fixedly connected to the top of the tape platform 5 at equal intervals; a first translation module 10 is slidably connected to the side of the tape platform 5 for driving the tape platform 5 to slide on the track 16; a first lifting module 9 is also provided at the bottom of the tape platform 5 for driving the tape platform 5 to slide up and down.

[0039] The adhesive tape platform 5 in the bonding device provided by the present invention uses the adhesive tape adsorption module 6 to adsorb adhesive tape of the same length, and then drives the adhesive tape platform 5 to slide to the battery cell platform 2 through the first translation module 10. Before the adhesive tape platform 5 moves, the first lifting module 9 needs to move the adhesive tape platform 5 upward to ensure that the adhesive tape platform 5 is above the battery cell platform 2 when it moves to the position of the battery cell platform 2.

[0040] like Figures 1 to 4 As shown, the top of the battery cell placement platform 2 is fixed with multiple battery cell adsorption modules 11 arranged at equal intervals, and the side of the battery cell placement platform 2 is slidably connected to a second translation module 15, which is used to drive the battery cell placement platform 2 to slide on the track 16; the bottom of the battery cell placement platform 2 is also provided with a second lifting module 14, which is used to drive the battery cell placement platform 2 to slide up and down.

[0041] The battery cell placement platform 2 in the bonding device provided by the present invention uses battery cell adsorption modules 11 arranged at equal intervals on the top to adsorb battery cells. The battery cell placement platform 2 can slide horizontally on the track 16 through the second translation module 15. When the tape placement platform 5 and the battery cell placement platform 2 are intersected to achieve the connection between the tape and the battery cell, the battery cell placement platform 2 can be driven to move upward through the second lifting module 14, and the tape placement platform 5 can move downward, so that the tape can be quickly transferred to the battery cell.

[0042] like Figure 6 As shown, the tape adsorption module 6 includes a support rod 61; a first air passage connection port 62 is provided on the support rod 61; a first heating rod 7 and a first temperature sensor 8 are respectively passed through one end of the support rod 61; a plurality of first air intake ports 63 are equidistantly arranged on the surface of the support rod 61; the first air intake ports 63 are used to adsorb tape.

[0043] In the bonding device provided by the present invention, when the tape adsorption module 6 is in use, the tape is cut by the tape application module 1 and transferred to the top of the support rod 61. The top of the support rod 61 draws air through the first air intake 63 to generate negative pressure, adsorbing the tape and achieving pre-fixation of the tape. When the tape is transferred to the battery cell along with the tape distribution platform 5, the first heating rod 7 is activated to promote the connection between the tape and the battery cell. The first temperature sensor 8 is used to sense the temperature of the first heating rod 7. The first air intake 63 is connected to the external air intake pipe.

[0044] like Figure 5 As shown, the battery cell adsorption module 11 includes a tray 111; a second air passage connection port 112 is provided on the tray 111; a second heating rod 12 and a second temperature sensor 13 are respectively passed through one end of the tray 111; a plurality of second air intake ports 113 are provided on the surface of the tray 111 at equal intervals, and the second air intake ports 113 are used to adsorb battery cells.

[0045] In use, the battery cell adsorption module 11 in the bonding device provided by the present invention carries the battery cell through the tray 111, and uses the second air intake 113 to draw air to generate negative pressure to fix the battery cell. When the tape-carrying platform 5 and the battery cell-carrying platform 2 intersect, the second heating rod 12 is activated to promote the transfer of the tape to the battery cell. The second temperature sensor 13 is used to sense the temperature of the second heating rod 12. The second air intake 113 is connected to the external air intake pipe. Finally, the battery cell with tape attached is transported by the battery string transport module 4.

[0046] like Figures 1 to 6 As shown, the width of the support rod 61 is less than the spacing between adjacent support plates 111, and the support rod 61 is used to support the tape that passes between adjacent support plates 111.

[0047] In the bonding device provided by the present invention, the width of the support rod 61 is smaller than the spacing between adjacent support plates 111. Furthermore, when adjacent battery cells are laid, the spacing also needs to be controlled to be greater than the width of the support rod 61 so that when the tape laying platform 5 and the battery cell laying platform 2 intersect, the support rod 61 can be inserted between adjacent support plates 111.

[0048] Working principle:

[0049] In the existing technology, the equipment used for applying tape to battery cells often requires a large space to arrange the track 16 for the pneumatic equipment to move. At the same time, it also requires the design of the air circuit layout of the pneumatic equipment, which is relatively complex and affects the efficiency of applying tape after the battery cells are arranged.

[0050] The bonding device provided by this invention uses an adhesive tape module 1 to cut adhesive tape of equal length and attach it to an adhesive tape platform 5. The adhesive tape platform 5 is then moved horizontally on a track 16 to a position directly above a battery cell platform 2. Subsequently, the adhesive tape platform 5 is controlled to move downwards to attach the adhesive tape to the battery cells supported on the surface of the battery cell platform 2. Adjacent battery cells are pre-supported on the battery cell platform 2, and gaps are reserved between adjacent battery cells to allow the adhesive tape platform 5 to pass through. When the adhesive tape platform 5 and the battery cell platform 2 intersect, the adhesive tape can be attached to the adjacent battery cells, thus completing the adhesive tape application operation for adjacent battery cells. Compared with the prior art, this bonding device has a simple structure and high completion rate, which can improve the efficiency of adhesive tape application to battery cells.

[0051] The tape adsorption module 6 adsorbs tape of equal length, and then the tape spreading platform 5 is driven to slide onto the battery cell spreading platform 2 by the first translation module 10. Before the tape spreading platform 5 moves, the tape spreading platform 5 needs to be moved up by the first lifting module 9 to ensure that the tape spreading platform 5 is above the battery cell spreading platform 2 when it moves to the position of the battery cell spreading platform 2. The battery cells are adsorbed by the battery cell adsorption modules 11 arranged at equal intervals on the top, and the battery cell spreading platform 2 can slide horizontally on the track 16 by the second translation module 15. When the tape spreading platform 5 and the battery cell spreading platform 2 are intersected to connect the tape and the battery cell, the battery cell spreading platform 2 can be moved up by the second lifting module 14, and the tape spreading platform 5 can be moved down, so that the tape can be quickly transferred onto the battery cell.

[0052] In the case of the tape adsorption module 6, the tape is cut by the tape application module 1 and transferred to the top of the support rod 61. The top of the support rod 61 draws air through the first air intake 63 to generate negative pressure, adsorbing the tape and achieving pre-fixation of the tape. When the tape is transferred to the battery cell along with the tape distribution platform 5, the first heating rod 7 is activated to promote the connection between the tape and the battery cell. The first temperature sensor 8 is used to sense the temperature of the first heating rod 7. The first air intake 63 is connected to an external air intake pipe. In the case of the battery cell adsorption module 11, the battery cell is supported by the support plate 111. The second air intake 113 draws air to generate negative pressure to fix the battery cell. When the tape distribution platform 5 carrying the tape intersects with the battery cell distribution platform 2, the second heating rod 12 is activated to promote the transfer of the tape to the battery cell. The second temperature sensor 13 is used to sense the temperature of the second heating rod 12. The second air intake 113 is connected to an external air intake pipe.
