Description

Technical Field

[0001] The present application belongs to the field of solar cell production, especially the field of cell string manufacturing. In particular, the present application relates to a conveying platform and a cell string welding machine. Background Art

[0002] The battery string is formed by stacking the welding tape and the battery cells in a predetermined order, and connecting the welding tape with the main grid line of the battery cell in series. A common process for serial welding of battery cells is to receive the battery cell group and welding tape group at the loading station by a conveyor belt, and move the battery cell group and welding tape group to be serially connected to the serial connection station, and then move the serially connected battery string to the unloading station. This method of conveying with a conveyor belt has many inconveniences. On the one hand, the conveyor belt is long, and its movement (for example, due to relaxation, deviation, etc.) will cause the relative position of the battery cells to change. On the other hand, there is a lot of wear and tear during the conveying process of the conveyor belt, and the conveyor belt needs to be replaced after long-term work, so the cost is also high.

[0028] The second driving mechanism is used to drive the second slide to move along the second direction on the second guide component.

[0029] The second driving mechanism is used to drive the second slide seat to slide on the second guide component, so as to adjust the position of the support plate perpendicular to the first direction.

[0030] According to some examples of the first aspect of the present application, the second driving mechanism includes:

[0031] a motor, the motor being mounted on the second slide and the output shaft of the motor being provided with a ratchet; and

[0032] The rack matched with the ratchet is arranged on the first sliding seat and extends along the second direction.

[0033] The cooperation between the ratchet and the rack enables the second sliding seat to slide in a direction perpendicular to the first direction.

[0034] According to some examples of the first aspect of the present application, the conveying platform further includes a tidying component, a avoidance opening is provided on the support plate, the tidying component can be driven to extend out of the avoidance opening and adjust the position of the welding ribbon group perpendicular to the first direction, and the tidying component includes:

[0038] In the above implementation, a regularization component is arranged on the pallet, and the regularization component arranged on the pallet can adjust the position of the solder ribbon group, thereby eliminating the position error caused by the solder ribbon conveying mechanism when placing the solder ribbon, so as to ensure the quality of the battery string connection.

[0044] The driving wheel is arranged on the support and drives the driven wheel through a belt.

[0045] The driving wheel drives the driven wheel through the belt, which in turn drives the ball screw to rotate.

[0048] The cam abuts against the upper portion of the inner peripheral wall, and the cam can be driven to rotate eccentrically.

[0049] The eccentric rotation of the cam causes the annular part to shift in the vertical direction, thereby causing the regular part to move up and down. When adjusting the position of the welding strip, the cam rotates to lift the annular part in the vertical direction, and the regular part extends out from the avoidance opening; after the welding strip position is adjusted, the cam rotates to lower the annular part in the vertical direction, and the regular part drops below the pallet through the avoidance opening to avoid affecting the laying of the battery cells.

[0075] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0076] For example, Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, Figure 1 is a schematic diagram of the structure of the conveying platform 100, Figure 2 For attachment Figure 1 A magnified schematic diagram of Figure 3 Schematic diagram of the structure of a pallet 111 . The present application provides a conveying platform 100 , including a moving device 110 and a pallet 111 disposed thereon.

[0077] The mobile device 110 moves back and forth along a first direction, which is the direction of battery cell conveyance, and the battery cells or battery cell groups are transported from different workstations through reciprocating motion. Among them, a pallet 111 is arranged on the mobile device 110 so that the pallet 111 can move back and forth with the mobile device 110, and the battery cell group to be transported is arranged above the pallet 111 to realize transportation. In addition, a welding ribbon group extending along the first direction is also arranged between the pallet 111 and the battery cell, and the battery cell group is laid on the welding ribbon group, so as to facilitate the serial connection of the battery cell group and the welding ribbon group in the next process. And an adsorption component 114 is configured on the pallet 111, and the adsorption component 114 adsorbs and positions the welding ribbon group and the battery cell group on the pallet 111 to ensure the position stability of the welding ribbon group and the battery cell group during transportation.

[0078] By setting the pallet 111 on the mobile device 110, the pallet 111 moves back and forth in the first direction with the mobile device 110, so that the pallet 111 can flow in each workstation to receive and convey the solder ribbon group and the battery cell group. This conveying device has a simple structure, strong durability, and easy maintenance. The structure of the pallet 111 can stably receive the solder ribbon group and the battery cell, and it is not easy to cause the solder ribbon group and the battery cell to move.

[0079] As one embodiment, the adsorption component 114 may include a vacuum generator (not shown in the drawings) and an adsorption hole 114a. The adsorption hole 114a is provided on the support plate 111. The vacuum generator is placed under the support plate 111. The adsorption hole 114a is connected to the vacuum generator, so that the adsorption force is generated through the adsorption hole 114a so that the welding ribbon group and the battery cell group are adsorbed and positioned on the support plate 111.

[0080] In one implementation, the adsorption holes 114 a include solder strip adsorption holes for adsorbing solder strips and battery cell adsorption holes for adsorbing battery cells. The solder strip adsorption holes and the battery cell adsorption holes can be controlled separately.

[0081] In one implementation, the adsorption holes 114a further include adhesive film adsorption holes for adsorbing adhesive films, and the adhesive film adsorption holes can be controlled individually.

[0082] For example, the support plate 111 structure for carrying the welding strip group and the battery cell group can be an integral support plate formed in one piece, or it can include a plurality of supporting blocks arranged side by side. Among them, the support plate 111 formed by a plurality of supporting blocks can be adapted to the support and transportation of battery cells of different specifications and spacings by adjusting the spacing between the supporting blocks. In addition, the support plate 111 formed by a plurality of supporting blocks is also convenient for interlacing the structure for adjusting the position of the welding strip between the supporting blocks, such as the regularization device described later.

[0083] As one of the embodiments, a heating component 115 is arranged below the bearing surface of the pallet 111, which can be a heating plate or a heating net, or the heating component can be a heating rod, or can be a heating net composed of heating wires; the heating component can be directly arranged inside the pallet 111, or can be attached to the bottom of the pallet 111, so as to heat the pallet 111; as shown in the accompanying drawings, the bearing surface of the pallet 111 is the top (upper) surface of the pallet 111; the heating component 115 is used to heat the welding ribbon group and the battery cell group located on the pallet 111, to increase the temperature of the welding ribbon group and the battery cell group, so as to facilitate the series connection mechanism 400 to implement compression and series connection.

[0084] In addition, an anti-sticking layer is formed on the support plate 111. Optionally, the anti-sticking layer may include one of a polytetrafluoroethylene coating, a ceramic coating, and a titanium metal coating, or the anti-sticking layer may be a Teflon tape attached to the support plate 111. The anti-sticking layer formed on the support plate 111 prevents the solder strips and battery cells from being stuck and damaged when placed on the support plate 111.

[0085] Example, with Figure 1 and attached Figure 3 There are two conveying platforms 100 shown in the figure, and the two conveying platforms 100 are arranged in parallel. Through the two conveying platforms 100 arranged in parallel, the two pallets 111 independently reciprocate along the first direction, so as to circulate in each station in turn (alternately), shortening the conveying time of the material flowing in each station and improving the processing efficiency.

[0086] Reference Figure 1 and attached Figure 2 As shown, the moving device 110 includes: a first guide member 112a extending along a first direction, a support plate 111 being slidably disposed on the first guide member 112a; and a first driving mechanism 112c, driving the support plate 111 to reciprocate along the first direction on the first guide member 112a. The first driving mechanism 112c drives the support plate 111 to reciprocate along the first direction on the first guide member 112a, so that the support plate 111 can carry the welding ribbon group and the battery cell group through the serial connection station. When in the serial connection station 5, the support plate 111 stays for a certain time for the welding ribbon group and the battery cell group to complete the serial connection; and the battery string formed by the serial connection of the welding ribbon group and the battery cell group is unloaded from the support plate 111 to the next process.

[0087] In this embodiment, the first driving mechanism drives the pallet 111 to reciprocate on the first guide component 112a extending along the first direction, so that the pallet 111 can flow through various workstations. This conveying platform 100 has a simple structure, high durability and easy maintenance.

[0088] Reference Figure 2As shown, a mechanism is provided to enable the support plate 111 to reciprocate in the first direction. In one embodiment, the mobile device 110 is provided with a first slide 112b that is relatively independent from the support plate 111. This relatively independent feature can be achieved by the support plate 111 and the first slide 112b being a detachable mounting and matching relationship. The first slide 112b forms a sliding match with the first guide component 112a, and the first slide 112b also forms a fixed support for the support plate 111. This detachable mounting and matching structure facilitates independent maintenance of each component.

[0089] Specifically, the moving device 110 also includes a first slide 112b, which is slidably set on the first guide component 112a, and the first slide 112b is used to support and fix the support plate 111. The first driving mechanism 112c provides driving force for the first slide 112b, and under the action of the driving force, the first slide 112b moves back and forth with the support plate 111 on the first guide component 112a.

[0090] In a specific implementation, the first driving mechanism 112c may include a main pulley, a slave pulley and a traction belt, the traction belt is wound around the main pulley and the slave pulley, the first slide 112b is located in front of the main pulley and the slave pulley, and can be pulled by the traction belt to achieve movement on the first guide component 112a, and the main pulley drives the traction belt under the action of the power source.

[0091] Continue to refer to the attached Figure 1 and attached Figure 3 As shown, the mobile device 110 is configured with a mechanism for realizing the reciprocating movement of the support plate 111 in the second direction. In an implementation example, the mobile device 110 also includes a second guide member 113a, a second slide 113b and a second drive mechanism 113c, and the second guide member 113a, the second slide 113b and the second drive mechanism 113c are arranged in the space between the first slide 112b and the support plate 111, wherein the second guide member 113a is arranged on the first slide 112b and extends along the second direction, and the second direction is perpendicular to the first direction on the horizontal plane, the second slide 113b is arranged on the second guide member 113a and forms a sliding fit with the second guide member 113a, and the support and fixation of the support plate 111 are formed by the second slide 113, and the second drive mechanism 113c provides a driving force to drive the second slide 113b to slide on the second guide member 113a, and it can be understood that the sliding is the movement of the second slide 113b along the extension direction (i.e., the second direction) of the second guide member 113a.

[0092] The mobile device 110 of this embodiment can adjust the position of the pallet 111 in two dimensions of the horizontal plane. Specifically, the pallet 111 can realize position adjustment in one dimension (first direction) based on the first guide component 112a, the first slide 112b and the first driving mechanism 112c. The position of the pallet 111 can be adjusted in another dimension (second direction) by driving the second slide 113b to slide on the second guide component 113a using the second driving mechanism 113c.

[0093] Exemplary, combined Figure 2 As shown, the second driving mechanism 113c described above includes a motor 113d and a rack 113f, the motor 113d is mounted on the second slide 113b, and the output shaft of the motor 113d is provided with a ratchet 113e, the rack 113f is arranged on the first slide 112b, and the rack 113f extends along the second direction (perpendicular to the first direction), the rack 113f and the ratchet 113e form a match, and the motor 113d drives the ratchet 113e to rotate, that is, through the match between the rack 113f and the ratchet 113e, the second slide 113b is realized to slide along the second direction (perpendicular to the first direction). It can be understood that, not limited to the matching structure of the rack 113f and the ratchet 113e, other mechanisms that can drive the second slide 113b to move in a direction perpendicular to the first direction can be applied to the present application.

[0094] Reference Figure 3 and attached Figure 4 As shown, in an implementation example, the conveying platform 100 further includes a tidying component, and an avoidance opening 111a is provided on the support plate 111. The tidying component can be driven to extend out of the avoidance opening 111a and adjust the position of the welding ribbon group perpendicular to the first direction.

[0095] Reference Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6As shown, the regularization component 116 includes a support 116a, a bottom plate 116b arranged on the support 116a, and a plurality of support plates 116c, wherein the plurality of support plates 116c are all mounted on the bottom plate 116b. Specifically, the support plates 116c may have a relatively thin thickness, and the plate surface is vertically mounted on the bottom plate 116b, and the plate surfaces of adjacent support plates 116c are spaced apart along the first direction. Among them, a lifting drive mechanism 117 and a position adjustment drive mechanism 118 are arranged on the support 116a, and the bottom plate 116b can be adjusted in height by the lifting drive mechanism 117, and can be adjusted in position perpendicular to the first direction by the position adjustment drive mechanism 118, and a row of regularization pieces 116d is formed on each support plate 116c. The regular piece 116d can be a block, a strip or other protruding extension structure, and the number of regular pieces 116d corresponds to the number of welding strips in the welding strip group 2. The number of regular pieces 116d corresponds to the number of welding strips in the welding strip group. With the help of the height adjustment described above, the regular piece 116d extends out from the avoidance opening 111a and touches the welding strip, thereby adjusting the position of the welding strip group, and then eliminating the position error caused by the welding strip conveying mechanism 200 when placing the welding strip, so as to ensure the quality of the battery string connection.

[0096] Reference Figure 6 As shown, for example, in order to ensure that the position of the solder strip is adjusted within the range of movement of the regulating piece 116d, and to prevent the solder strip from deviating due to inertial and unrestricted movement, each regulating piece 116d is provided with a groove 116e, which is used to accommodate the solder strip when the regulating piece 116d extends out of the opening 111a. The groove 116e accommodates the solder strip, and the regulating piece 116d can be driven to adjust the position of the solder strip. In this example, the solder strip accommodated in the groove 116e always moves with the regulating piece 116d, and the movement range is controlled, so as to achieve relatively accurate position adjustment.

[0097] Reference Figure 5 As shown, as an implementation example of the positioning drive mechanism 118, the positioning drive mechanism 118 includes a ball screw, a mounting portion arranged on the base plate 116b, and a driving wheel arranged on the support 116a. The ball screw includes a ball nut and a screw matched with the ball nut. The ball nut is mounted on the support 116a. The screw passing through the ball nut has one end connected with the mounting portion by threaded engagement, and the other end is equipped with a driven wheel. The driving wheel drives the driven wheel through a belt to drive the ball screw to rotate. The rotation of the ball screw can drive the regular piece 116d to move in a direction perpendicular to the first direction. After the welding strip is placed on the support plate 111, the position can be adjusted along with the movement of the regular piece 116d.

[0098] Reference Figure 5As shown in the figure, as an implementation example of the lifting drive mechanism 117, the lifting drive mechanism 117 includes a ring and a cam installed in the ring, the ring is installed on a side wall of the support 116a, the ring is sleeved outside the cam, and the cam is in contact with the upper part of the inner peripheral wall defined by the ring, and there is always a gap between the inner peripheral wall and the cam in the horizontal direction. The inner peripheral wall defined by the ring has a first inner diameter along the horizontal direction and a second inner diameter along the vertical direction, and the first inner diameter is larger than the second inner diameter.

[0099] The cam can be driven to rotate eccentrically, and the cam never touches the inner circumferential wall of the ring in the horizontal direction when rotating. The eccentric rotation of the cam causes the ring to move in the vertical direction and thus adjust the height of the bottom plate 116b, thereby enabling the regular piece 116d to move up and down through the avoidance opening 111a.

[0100] When adjusting the position of the welding strip, the cam rotates to the position of lifting the annular part in the vertical direction, and the regulating piece 116d extends from the avoidance opening 111a, thereby touching the welding strip on the support plate 111 and realizing the position adjustment; after completing the welding strip position adjustment, the cam rotates to the position of lowering the annular part in the vertical direction, and the regulating piece 116d is lowered to below the support plate 111 through the avoidance opening 111a to avoid affecting the laying of the battery cells.

[0101] Based on the same application concept, the embodiment of the present application also provides a battery stringing machine 1, including a conveying platform 100, a welding strip conveying mechanism 200, a battery cell conveying mechanism 300 and a stringing mechanism 400 provided according to the embodiment of the first aspect of the present application.

[0102] Specifically, the conveying platform 100 adopts the structure described above, and the pallet 111 has a loading station, an unloading station, and a series connection station located between the loading station and the unloading station when it moves back and forth along the first direction; the solder strip conveying mechanism 200 is arranged on one side adjacent to the loading station, and is used to convey the solder strip group to the pallet 111 at the loading station; the battery cell conveying mechanism 300 is arranged on the other side adjacent to the loading station, and is used to convey the battery cell group to the pallet 111 at the loading station, and stack it on the upper surface of the solder strip group; the series connection mechanism 400 is arranged adjacent to the series connection station, and when the solder strip group and the battery cell group are transported to the series connection station by the pallet 111, the series connection mechanism 400 presses the battery cell group and the solder strip group and heats them, so that the solder strip group is hot-melted and fixed on the surface of the battery cell group.

[0103] The conveying platform 100 used in the battery string welding machine 1 is highly durable and easy to maintain, and the support plate structure can stably support the welding ribbon group and the battery cells, and is not likely to cause the welding ribbon group and the battery cells to move.

[0104] In the description of this specific embodiment, the "adjacent setting" method refers to the spatial position of one mechanism being close to or adjacent to another mechanism or a part of another mechanism, so that the movement of the two mechanisms is smoother and more efficient when materials flow between the two mechanisms or when other operations requiring the connection or cooperation of the two mechanisms are performed.
