Detailed Description
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
The prior battery piece conveying device is used for conveying the welding strip to be welded and the battery piece, and the welding strip is positioned on the battery piece firstly by utilizing the elastic pin pressing mechanism and then conveyed to the welding area for welding. The problem that it exists lies in that the elasticity is pressed needle mechanism and is led to the fact sheltering from to the position that the welding strip was pressed by the needle spare, leads to the welding strip to be pressed the position unable to reach with other positions the same heating effect, finally leads to the welding effect unstable, the easy problem that the rosin joint leaks and welds. In addition, when the heating lamp box heats the welding strip, part of heat can be absorbed by the elastic needle pressing mechanism.
In order to provide the battery piece conveying device, the welding belt and the battery pieces are conveyed by adopting the battery piece conveying device, and the battery pieces can be welded into strings without using an elastic pin pressing mechanism.
As shown in fig. 1 to 3, the battery piece conveying device in the embodiment of the utility model includes a conveying belt 1 and a supporting portion for supporting the conveying belt 1, wherein:
the support part comprises a cloth string section 2 and a welding section 3 which are sequentially arranged along the conveying direction (such as the X-axis direction in fig. 1) of the conveying belt 1, wherein a welding belt adsorption hole for adsorbing the welding belt and a first battery piece adsorption hole for adsorbing the battery piece are formed in the cloth string section 2. The welding section 3 is provided with a second battery piece adsorption hole for adsorbing the battery piece.
The conveyer belt 1 is provided with a first air vent 11 matched with the welding belt adsorption hole and a second air vent 12 matched with the first battery piece adsorption hole and the second battery piece adsorption hole.
The welding belt to be welded and the battery piece are sequentially laid on the conveying belt 1 running on the cloth string section 2, the welding belt adsorption holes are used for adsorbing the welding belt on the conveying belt 1 through the first air holes 11, and the first battery piece adsorption holes are used for adsorbing the battery piece on the conveying belt 1 through the second air holes 12, so that the battery piece is pressed on the corresponding welding belt.
The conveying belt 1 is used for conveying the laid welding belt and the battery piece to the welding section 3, and the second battery piece adsorption Kong Jingdi and the second ventilation holes 12 are used for adsorbing the battery piece to the conveying belt 1 so that the battery piece is pressed on the corresponding welding belt. In addition, as the welding section 3 is not provided with the welding strip adsorption hole, heat on the welding strip can be prevented from being dissipated through the welding strip adsorption hole in the welding process, the welding effect is affected, and the cold joint is prevented from being leaked.
Of course, in order to drive the conveyor belt 1, a drive wheel group is provided on the support portion, and the conveyor belt 1 is wound around the drive wheel group.
Taking a back contact battery piece as an example, the specific working process of the battery piece conveying device in the embodiment of the utility model is as follows:
firstly, a welding strip is paved on a conveying belt 1 running on a cloth string section 2, and the welding strip is adsorbed on the conveying belt 1 through a first air hole 11 by a welding strip adsorption hole, so that the welding strip is prevented from being deviated before battery pieces are paved, and the welding strip cannot be accurately positioned on grid lines of the corresponding battery pieces.
Then, the back of the battery piece is laid down on the corresponding welding strip, and the first battery piece adsorption Kong Jingdi and the second ventilation holes 12 adsorb the battery piece on the conveying belt 1, so that each battery piece is pressed on the corresponding welding strip, and the welding strips are ensured to be accurately positioned on the grid lines of the corresponding battery piece.
Then, the conveyor belt 1 conveys the laid welding strips and the battery pieces to the welding section 3, and the second battery piece adsorption Kong Jingdi and the second ventilation holes 12 continuously adsorb the battery pieces to the conveyor belt 1, so that each battery piece keeps a state of being pressed on the corresponding welding strip, namely, the welding strip is ensured to be still positioned on the grid line of the corresponding battery piece before welding.
Finally, a welding mechanism located above the welding section 3 heats the welding strip and the battery piece, thereby welding the laid welding strip and the battery piece into a string.
Therefore, the battery piece conveying device does not need to additionally adopt an elastic pin pressing mechanism to position the welding belt, so that the welding effect is improved, and the risk of cold joint and cold joint leakage is reduced.
In order to ensure that the battery piece is not loosened at the welding section 3, the adsorption force of the second battery piece adsorption hole to the battery piece is larger than that of the first battery piece adsorption hole to the battery piece, namely, the negative pressure generated at the second battery piece adsorption hole is not smaller than the sum of the negative pressures generated at the first battery piece adsorption hole and the welding strip adsorption hole.
The conveyor belt 1 is liable to slightly swing in a first direction (e.g., Y-axis direction in fig. 1) perpendicular to the conveying direction during conveying, and in addition, if the first ventilation holes 11 and the solder-ribbon suction holes are equal in width in the first direction when the diameters of the first ventilation holes 11 and the solder-ribbon suction holes are small, when the conveyor belt 1 slightly swings, the first ventilation holes 11 and the solder-ribbon suction holes are caused to be staggered, so that the solder-ribbon suction holes cannot perform effective suction of the solder ribbon.
In order to solve this problem, alternatively, the width of the first ventilation holes 11 in the first direction is set to be larger than the width of the solder ribbon suction holes in the first direction, so that even if the conveyor belt 1 is slightly swung, it is ensured that the first ventilation holes 11 and the solder ribbon suction holes still penetrate. For example, as shown in fig. 3, the first ventilation holes 11 are kidney-shaped holes having a large width extending in the first direction.
Of course, the width of the solder ribbon suction hole in the first direction may be set to be larger than the width of the first ventilation hole 11 in the first direction.
With continued reference to fig. 1, optionally, the cloth string section 2 includes at least one first base 23, and the solder strip adsorption hole and the first battery piece adsorption hole are both disposed on the first base 23, and a first air extraction channel communicated with the solder strip adsorption hole and a second air extraction channel communicated with the first battery piece adsorption hole are disposed in the first base 23. Through the first passageway of bleeding, can make the welding area adsorption port produce the adsorption affinity, through the second passageway of bleeding, can make first battery piece adsorption port produce the adsorption affinity.
The first base 23 may also be provided as a unitary structure. Of course, in order to facilitate the processing of the first air extraction channel and the second air extraction channel, the first base 23 may also be configured as a split structure, for example, as shown in fig. 4 to 6, the first base 23 includes a bottom plate 231 and a carrying plate 232, where: the carrying plate 232 is used for carrying the conveyor belt 1, and a plurality of rows of solder strip adsorption holes 21 and a plurality of rows of first battery piece adsorption holes 22 are arranged on the carrying plate 232 along the conveying direction of the conveyor belt 1. Correspondingly, the bottom plate 231 is provided with a plurality of first air extraction channels 233 which are in one-to-one correspondence and communicated with the rows of solder strip adsorption holes 21, and a plurality of second air extraction channels 234 which are in one-to-one correspondence and communicated with the rows of first battery piece adsorption holes 22.
After the carrier plate 232 is mounted on the bottom plate 231 in a snap-fit manner, each first air extraction channel 233 is communicated with the corresponding row of solder strip adsorption holes 21, and each second air extraction channel 234 is communicated with the corresponding row of first battery piece adsorption holes 22.
With continued reference to fig. 5, in order to prevent the suction interference from occurring between the solder ribbon suction hole 21 and the first battery piece suction hole 22. Alternatively, the solder-ribbon suction holes 21 and the first battery-piece suction holes 22 are arranged in a staggered manner in a direction perpendicular to the conveying direction of the conveying belt (i.e., the first direction).
In order to perform the suction of the first suction channel 233 and the second suction channel 234 in the first base 23, the suction force is generated in the solder ribbon suction hole 21 and the first battery piece suction hole 22.
As shown in fig. 1, in some alternative embodiments, the battery piece conveying device of the present utility model further includes a first air extraction mechanism 4, where the air extraction ends of the first air extraction mechanism 4 are respectively abutted with the air outlet ends of the first air extraction channel 233 and the second air extraction channel 234. In addition, the first air extraction mechanism 4 is further provided with a valve body for controlling the air extraction end of the first air extraction mechanism 4 to be communicated with or cut off from the air outlet end of the second air extraction channel 234.
Before the welding strip is laid on the conveying belt 1 running on the stringing section 2, the first air suction mechanism 4 pumps air from the first air suction channel 233, and the valve body cuts off the air suction end of the first air suction mechanism 4 and the air outlet end of the second air suction channel 234. That is, at this time, the solder ribbon suction hole 21 has suction force, while the first battery piece suction hole 22 does not have suction force. In this way, it is ensured that the solder tape can be accurately laid to a predetermined position under the suction of the solder tape suction hole 21 without being affected by the first battery piece suction hole 22.
After the butt welding tape is laid, the control valve body releases the partition of the air extraction end of the first air extraction mechanism 4 and the air outlet end of the second air extraction channel 234, so that the first battery piece adsorption hole 22 has adsorption force. So that the laid battery pieces can be adsorbed on the conveyor belt 1.
Of course, for convenience of control, two independent sets of air pumping mechanisms may be provided to perform the respective air pumping of the first air pumping channel 233 and the second air pumping channel 234. For example, as shown in fig. 7 and 9, in another alternative embodiment, the battery piece conveying device of the present utility model includes a first air extraction mechanism 4 and a second air extraction mechanism 5, where the air extraction end of the first air extraction mechanism 4 is abutted with the air outlet end of the first air extraction channel 233, and the air extraction end of the second air extraction mechanism 5 is connected with the air outlet end of the second air extraction channel 234.
The first suction mechanism 4 sucks the first suction passage 233 and the second suction mechanism 5 does not suck the second suction passage 234 before the solder tape is laid on the conveyor 1 running onto the stringer 2. That is, at this time, the solder ribbon suction hole 21 has suction force, while the first battery piece suction hole 22 does not have suction force. In this way, it is ensured that the solder tape can be accurately laid to a predetermined position under the suction of the solder tape suction hole 21 without being affected by the first battery piece suction hole 22.
After the butt welding belt is laid, the second air suction mechanism 5 pumps air to the second air suction channel 234, so that the first battery piece adsorption holes 22 have adsorption force, and the laid battery pieces are adsorbed on the conveying belt 1. At the same time, the first pumping mechanism 4 may keep pumping the first pumping channel 233.
As shown in fig. 7 and 8, optionally, the surface of the cloth string section 2 is further provided with a first extending groove 24 and a second extending groove 25, where the solder strip adsorption hole is located in the first extending groove 24, and the first extending groove 24 is used for enlarging the area of the negative pressure area formed by the solder strip adsorption hole, so as to enlarge the adsorption area of the solder strip adsorption Kong Duihan strip in the length direction, and finally improve the adsorption effect of the solder strip. The first battery piece adsorption hole is located in the second extension groove 25, and the second extension groove 25 is used for enlarging the area of the negative pressure area formed by the first battery piece adsorption hole, so that the adsorption area of the first battery piece adsorption hole to the battery piece is enlarged, and finally the adsorption effect to the battery piece is improved.
The implementation structure of the cloth string section 2 has been described above by way of example. Alternatively, the welding section 3 in the embodiment of the present utility model may have a similar structure to the cloth string section 2. For example, as shown in fig. 1, the welding section 3 includes at least one second base 31, the second battery piece adsorption hole is disposed on the second base 31, and a third air suction channel communicating with the second battery piece adsorption hole is disposed in the second base 31. Through the third air suction channel, the second battery piece adsorption hole can generate adsorption force. Likewise, the second base 31 may be of a unitary structure. The second base 31 may also be a split structure including a bottom plate and a carrier plate.
Similarly, in order to perform the air extraction of the third air extraction channel in the second base 31 so that the second battery piece adsorption hole generates the adsorption force, the battery piece conveying device of the present utility model optionally further includes a third air extraction mechanism, and an air extraction end of the third air extraction mechanism is in butt joint with an air outlet end of the third air extraction channel.
With continued reference to fig. 1, optionally, the cloth string section 2 and the welding section 3 are respectively provided with an electric heating component 6 and a heat dissipation component 7, where the electric heating component 6 can perform preheating on the battery piece and the welding strip before welding, so as to shorten the welding time of the welding mechanism and improve the welding efficiency. The heat dissipation assembly 7 can dissipate heat of the cloth string section 2 and the welding section 3. The electric heating element 6 may be, for example, a heating rod, and the heat dissipating element 7 may be, for example, a heat sink.
