According to the battery tool of the embodiment of the first aspect of the present application, referring to fig. 1, the battery tool includes a base 100, a positioning mechanism 200, a first driving member 300 and a welding mechanism 400, the positioning mechanism 200 is disposed on the base 100 and is used for positioning a battery 500, the first driving member 300 has a driving portion, the driving portion is fixedly connected to the base 100 and is used for driving the base 100 to rotate around a first central axis, that is, the first central axis is a rotation center of the driving portion and coincides with a central axis of a pole of the battery. (the first central axis and the preset direction in the case are only one self-defined feature so as to explain the position relation with other technical features in the following, and the writing method has no unclear problems)
Specifically, by adopting the jig, the battery is positioned on the positioning mechanism 200, the first driving member 300 drives the base 100 to rotate, and the base 100 drives the positioning mechanism 200 to rotate, so as to drive the battery to rotate; meanwhile, the external welding mechanism 400 can be fixedly installed on one side of the jig and emits laser to a welding position between the pole of the battery 500 and the top cover of the battery 500, so that the circumferential welding of the welding position is realized in the rotation process of the battery 500; in addition, the rotation of the battery 500 is adopted to replace the rotation of the welding mechanism 400, so that the structure of the welding mechanism 400 is simplified, and the manufacturing difficulty and the manufacturing cost of the welding device are reduced.
It should be noted that, especially for the double-top cap battery 500, the terminal of the double-top cap battery 500 is engaged with the top cap, and the exposed top cap portion is long, and the welding device for the battery 500 can perform circumferential welding of the welding position for the double-top cap battery 500 better.
In some embodiments, referring to fig. 1 and 2, the positioning mechanism 200 includes a bottom positioning assembly 210 and a top positioning assembly 220, the bottom positioning assembly 210 having a bottom positioning slot 213 for positioning the bottom of the battery 500; similarly, the top positioning component 220 is disposed right above the bottom positioning component 210, and the top positioning component 220 has a top positioning groove 224 (refer to fig. 5) disposed opposite to the bottom positioning groove 213, so as to position the top of the battery 500; from the top, it can be seen that battery 500 is positioned vertically between bottom positioning assembly 210 and top positioning assembly 220.
In some embodiments, referring to fig. 2 and 3, the bottom positioning assembly 210 includes a first mounting seat 211, a bottom positioning element 212 and an elastic resetting element, the first mounting seat 211 is horizontally fixed on the base 100 by a bolt, the bottom positioning element 212 is horizontally installed on the first mounting seat 211, and the bottom positioning slot 213 is horizontally opened at the top of the bottom positioning element 212 and is formed in a rectangular shape to fit the square battery 500.
Further, a horizontally fixed guide rail is arranged on the first mounting seat 211, the bottom positioning element 212 is horizontally slidably disposed on the first mounting seat 211 through the guide rail, and the horizontal sliding direction of the bottom positioning element 212 is a preset direction, i.e., a left-right direction in the drawings of the specification; meanwhile, the elastic reset member is horizontally disposed between the first mounting seat 211 and the bottom positioning member 212 (not shown in the figure), and can enable the bottom positioning member 212 to be always reset to the initial position. It should be noted that, when the bottom positioning element 212 is at the initial position, the central line of the pole of the battery 500 coincides with the first central axis, so that the laser beam emitted by the laser head 430 can be always obliquely emitted to the welding position, thereby realizing circumferential welding of the welding position.
By adopting the above scheme, when the user positions the battery 500, the bottom positioning member 212 can move along the preset direction, so that the battery 500 can be conveniently placed in the bottom positioning groove 213. Particularly, the battery 500 is placed by the manipulator, and when the manipulator places the battery 500, there is an error in the preset direction of the battery 500, so that the battery 500 cannot be placed in the bottom positioning groove 213. By adopting the manner, the bottom positioning member 212 can be adjusted along the preset direction, so that the manipulator can accurately place the battery 500 in the bottom positioning groove 213; and, after the battery 500 is placed, the bottom positioning piece 212 can reset to the initial position under the effect of the elastic reset piece, so that the welding position can be welded in the accurate circumferential direction.
In some embodiments, the elastic restoring member is a horizontally disposed spring, and the number of the springs is two, and the springs are respectively abutted against the left side and the right side of the bottom positioning member 212; specifically, the two springs are a first spring and a second spring, the first spring is disposed on the left side of the bottom positioning element 212, the left end of the first spring abuts against the first mounting seat 211, and the right end of the first spring abuts against the left side of the bottom positioning element 212, so that a rightward elastic restoring force can be applied to the bottom positioning element 212; the second spring is arranged on the right side of the bottom positioning piece 212, the left end of the second spring abuts against the right side of the bottom positioning piece 212, and the right end of the second spring abuts against the first mounting seat 211, so that a leftward elastic reset force can be applied to the bottom positioning piece 212; by adopting the above manner, the top positioning member 212 can be moved left and right, so that the battery 500 can be placed in the bottom positioning groove 213; and, the bottom positioning member 212 is returned to the initial position by the cooperation of the two springs.
In some embodiments, the battery 500 is further conveniently placed in the bottom positioning groove 213, the bottom positioning groove 213 has four side walls, an outwardly expanding first guide inclined surface 214 is obliquely arranged between each side wall and the top plane of the bottom positioning groove 213, and the four first guide inclined surfaces 214 are sequentially connected end to end, so as to form a first guide hole 215 that enlarges the placement opening of the bottom positioning groove 213, and the battery 500 slides into the bottom positioning groove 213 through the first guide hole 215, so as to achieve the placement of the battery 500.
It should be noted that, among the four first guiding inclined surfaces 214, two first guiding inclined surfaces 214 are respectively located at the left side and the right side of the bottom positioning groove 213, that is, one first guiding inclined surface 214 is inclined to the left, one first guiding inclined surface 214 is inclined to the right, and the guide rails on the first mounting seat 211 are arranged from the left to the right, so that the two first guiding inclined surfaces 214 are respectively inclined to the predetermined direction. By adopting the above arrangement, when the manipulator places the battery 500 in the bottom positioning groove 213, there is a left deviation between the battery 500 and the bottom positioning groove 213, and at this time, when the manipulator places the battery 500 downward, the battery 500 pushes the bottom positioning element 212 to slide leftward through the first guiding inclined plane 214 on the left side of the first guiding hole 215, thereby realizing the placement of the battery 500; similarly, there is a deviation to the right between the battery 500 and the bottom positioning slot 213, and at this time, when the manipulator places the battery 500 downwards, the battery 500 pushes the bottom positioning element 212 to slide to the right through the first guiding inclined plane 214 on the right side of the first guiding hole 215, so as to place the battery 500.
In some embodiments, referring to fig. 2 and 4, the top positioning assembly 220 further comprises a second mounting seat 221, a second driving member 222 and a top positioning member 223, wherein the second mounting seat 221 is vertically fixed on the base 100 and is located at one side of the bottom positioning assembly 210. The top positioning element 223 is horizontally disposed on one side of the second mounting seat 221 close to the bottom positioning assembly 210 and is located right above the bottom positioning element 212, and the top positioning element 223 is opened at the lower side of the top positioning groove 224, so as to be disposed opposite to the bottom positioning groove 213 (see fig. 5); meanwhile, one side of the second installation seat 221, which is close to the bottom positioning assembly 210, is provided with a vertically arranged guide rail, and the top positioning element 223 is vertically arranged on the second installation seat 221 in a sliding manner through the guide rail; and, the second driving member 222 is a vertically disposed cylinder, and a piston rod of the cylinder is fixedly connected to the top positioning member 223, so as to drive the top positioning member 223 to vertically slide.
By adopting the above manner, under the action of the second driving element 222, the top positioning element 223 moves upwards, so that the bottom positioning element 212 and the top positioning element 223 have a larger distance, thereby facilitating the manipulator to place the battery 500 in the bottom positioning slot 213; after the primary placement of the battery 500 is completed, the second driving member 222 drives the bottom positioning member 212 to move downward, so that the top of the battery 500 is embedded in the top positioning groove 224, thereby positioning the top of the battery 500.
It should be noted that a circular abdicating hole 227 is vertically formed in the top positioning element 223, and a central axis of the abdicating hole 227 coincides with the first central axis; that is, when the battery 500 is positioned between the bottom positioning member 212 and the top positioning member 223, the top positioning member 223 covers the top cover of the battery 500; moreover, the cross section of the abdicating hole 227 is large enough, the pole of the battery 500 is arranged in the abdicating hole 227 in a penetrating manner, and the laser beam can irradiate to the welding position through the abdicating hole 227. It can be seen that, through the arrangement of the top positioning member 223, not only the top positioning of the battery 500 is realized, but also the covering of the top cover of the battery 500 is realized, and the laser beam is prevented from being emitted onto the top cover, so that the scrapping of the battery 500 is avoided.
Further, referring to fig. 5, a third guiding hole 228 is formed between a side wall of the receding hole 227 and a top plane of the top positioning member 223, which is expanded outward, that is, the third guiding hole 228 is in a truncated cone shape, and the third guiding hole 228 is gradually enlarged from a lower port to an upper port thereof, so that the laser beam can be obliquely irradiated to the welding position along an inclined surface of the third guiding hole 228 by the arrangement of the third guiding hole 228; by adopting the above manner, the third guiding hole 228 ensures that the diameter of the abdicating hole 227 can be designed to be small enough, so that the top positioning piece 223 can cover the top cover of the battery 500 in a large range; meanwhile, the third guide hole 228 enables the laser beam to pass through the abdicating hole 227 obliquely, thereby irradiating to the welding site.
In some embodiments, it is further convenient for the battery 500 to be placed in the top positioning groove 224, the top positioning groove 224 has four side walls, a second guiding inclined surface 225 which expands outwards is obliquely arranged between each side wall and the bottom plane of the top positioning groove 224, and the four second guiding inclined surfaces 225 are sequentially connected end to form a second guiding hole 226 which enlarges the placement opening of the top positioning groove 224, and the battery 500 slides into the top positioning groove 224 through the second guiding hole 226, thereby achieving the top positioning of the battery 500.
It should be noted that, among the four second guiding inclined planes 225, two second guiding inclined planes 225 are respectively located at the left side and the right side of the top positioning groove 224, that is, one second guiding inclined plane 224 is inclined to the left, one second guiding inclined plane 224 is inclined to the right, and the guide rails on the first mounting seat 211 are arranged from the left to the right, so that the two second guiding inclined planes 224 are respectively inclined to the predetermined direction. By adopting the above arrangement, when the top positioning element 223 moves downward, there is a deviation to the left between the battery 500 and the top positioning slot 224, therefore, the top positioning element 223 pushes the battery 500 to move rightward through the second guiding inclined plane 225 on the left side of the second guiding hole 226, so that the top of the battery 500 can be embedded into the top positioning slot 224; similarly, there is a left deviation between the battery 500 and the top positioning groove 224, and therefore, the top positioning member 223 pushes the battery 500 to move to the left through the second guiding inclined surface 225 on the right side of the second guiding hole 226, so that the top of the battery 500 can be inserted into the top positioning groove 224. In summary, due to the two second guiding slopes 225, even if the spring is used for a long time, the bottom positioning element 212 cannot be preferably reset to the initial position, the two second guiding slopes 225 can adjust the position of the battery 500, and the bottom positioning element 212 is synchronously adjusted, so that the top of the battery 500 is accurately inserted into the top positioning groove 225.
In some embodiments, referring to fig. 2, the first driving member 300 is a stepping motor vertically disposed, a driving shaft of the stepping motor is disposed vertically upward, and the driving portion is an end portion of the driving shaft of the stepping motor, whereby the driving shaft of the stepping motor is fixedly connected with the lower surface of the base 100, thereby driving the base 100 to rotate about the first central axis.
In some embodiments, the welding device for the battery 500 further includes a third driving member 600, the third driving member 600 is a horizontally disposed rodless cylinder, the length direction of the rodless cylinder is parallel to the preset direction, and thus, the rodless cylinder has a sliding portion sliding along the preset direction, and the first driving member 300 is vertically fixed on the sliding portion. Therefore, through the arrangement of the third driving member 600, the third driving member 600 drives the positioning mechanism 200 to move in the left and right direction preset direction until the positioning mechanism moves to a required position, so that the battery 500 can be conveniently placed at the position by the manipulator.
According to the welding set of second aspect embodiment, including foretell battery tool and welding mechanism, welding mechanism can send laser to the battery to make the welding position welding between the top cap of battery and the utmost point post of battery.
