Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a material pushing device, a positioning system and welding equipment. Background Art

[0002] When manufacturing blade batteries, a welding device is required to weld and secure the battery housing and end caps. Before welding the housing and end caps, a pushing device is often used to push the battery into a rotary positioning device. The rotary positioning device clamps the battery in place and drives it to rotate, while a welding device welds the end caps to the battery housing.

[0003] When the pusher pushes the battery into the rotating positioning device, the end face of the battery away from the pusher needs to be pushed until it is against the positioning surface of the end face positioning device to ensure the consistency of the battery end face position. However, when the conventional pusher pushes the battery, the battery is prone to deviation (such as Figure 1 As shown, Figure 1 (The green dashed line in the middle represents the position of the battery after displacement, and the black solid line represents the position of the battery before displacement.) As a result, the end face of the battery does not fit well with the positioning surface, and thus cannot meet the requirements for end face position consistency. As a result, the battery will slide slightly during secondary positioning in the rotation positioning device, which may cause minor scratches on the battery end face. At the same time, since the consistency of the battery end face position cannot be guaranteed, the battery will be inaccurately positioned during welding, the welding trajectory will shift, and the problem of burning the terminal during welding will occur, resulting in a high battery scrap rate. Utility Model Content

[0004] Based on this, it is necessary to provide a pushing device, positioning system and welding equipment that can ensure the consistency of the battery end face position and reduce the scratching and scrapping of the battery in order to address the problem that the pushing device in traditional technology cannot ensure the consistency of the battery end face position when pushing the battery, which causes the battery to be scratched or directly scrapped.

[0008] A blocking portion is provided at one end of the mounting plate facing the pusher plate;

[0009] The push plate has a pushing plane. When the push plate pushes materials through the pushing plane, the first elastic member is compressed, and the surface of the push plate facing the mounting plate contacts the resisting portion. When the push plate is subjected to a force, it can slide relative to the mounting plate in a plane parallel to the pushing plane under the action of the first elastic member and the resisting portion.

[0010] In one embodiment, the middle portion of the surface of the pusher plate facing away from the first elastic member is recessed, and the pusher plane is formed on the peripheral portion of the pusher plate, and the peripheral portion is arranged outside the middle portion.

[0016] In one embodiment, a first mounting groove is provided on the mounting plate, the balls correspond to the first mounting grooves one-to-one, and the balls are partially embedded in the corresponding first mounting grooves.

[0017] In one embodiment, the pushing device further includes a limiting plate, the limiting plate is connected to the mounting plate and defines an accommodating cavity, the accommodating cavity has an opening, and the opening is formed on the limiting plate;

[0018] The push plate includes a push plate and a positioning plate that are connected to each other. The push plate, the first elastic member and the resisting portion are all located in the accommodating cavity, and the push plate is abutted against the limiting plate under the action of the first elastic member. The positioning plate extends out of the accommodating cavity through the opening, and the push plane is located on the portion of the positioning plate that extends out of the accommodating cavity.

[0019] In one embodiment, one end of the positioning plate connected to the push plate has a step portion, the step portion and the push plate form a limiting groove, and the limiting plate extends into the limiting groove to limit the push plate from extending out of the accommodating cavity.

[0020] In one embodiment, a first gap is provided between the push plate and the resisting portion, so that a second gap is formed between the push plate and the limiting plate when the positioning plate pushes the material.

[0021] In one embodiment, the first elastic member is a spring;

When the push plate continues to push the battery, the battery will apply a force to the push plate due to the limitation of the positioning surface, and the first elastic member will deform elastically. At this time, the push plate slides relative to the mounting plate in a plane parallel to the material pushing plane under the elastic deformation of the first elastic member and the resisting action of the resisting portion. There is a slight movement between the material pushing plane and the battery end face, compensating for the positioning error between the battery end face and the positioning surface, so that the battery end face is completely attached to the positioning surface, and finally the requirement of end face consistency is achieved. Since the battery end face positioning is consistent, when the rotary positioning device performs secondary positioning on the battery, the battery will not slide, and it is not easy to cause scratches on the battery end face. At the same time, during welding, the welding track will not shift, and the pole column will not be burned during welding, and the battery scrap rate is greatly reduced. Description of the Drawings

[0047] An embodiment of the present application provides a welding device for welding a battery 200. Optionally, the battery 200 is a blade battery 200, and the welding device is used to weld the housing of the blade battery 200 to the end cover. In other embodiments, the type of the battery 200 is not limited.

[0048] Refer to Figure 2 , the welding device includes a positioning system 100 and a welding device. The positioning system 100 is used to position the battery 200, and the welding device can weld the battery 200 positioned by the positioning system 100.

[0049] The positioning system 100 includes a pusher device 10, a rotary positioning device 20, and an end face positioning device 30. The pusher device 10 and the end face positioning device 30 are respectively located at both ends of the rotary positioning device 20. The pusher device 10 is used to push the end face of one end of the battery 200 and push it into the rotary positioning device 20. The end face positioning device 30 has a positioning surface 31, and the positioning surface 31 can abut against the other end face of the battery 200, so that the positions of the end faces of the batteries 200 pushed into the rotary positioning device 20 are consistent. The rotary positioning device 20 can clamp and position the battery 200, and the welding device can weld the battery 200 clamped by the rotary positioning device 20. The rotary positioning device 20 can also drive the battery 200 to rotate, so that the welding device can perform continuous full-weld welding on various parts around the battery 200. For example, the welding device can laser-weld the periphery of the housing to the end cover together.

[0050] In some embodiments, referring to Figures 3 - 5 , the pusher device 10 includes a pusher driving member 11, a mounting plate 12, a pusher plate 13, and a first elastic member 14. The mounting plate 12 is connected to the driving end of the pusher driving member 11, and the first elastic member 14 is disposed between the mounting plate 12 and the pusher plate 13. The pusher driving member 11 can drive the mounting plate 12 to move, so as to drive the first elastic member 14 and the pusher plate 13 to move for pushing. Optionally, the pusher driving member 11 is a cylinder, and the telescopic movement of the piston rod of the cylinder can drive the mounting plate 12, the first elastic member 14, and the pusher plate 13 to move. The first elastic member 14 is a spring, and the spring is disposed between the pusher plate 13 and the mounting plate 12. Of course, in some other embodiments, the type of the pusher driving member 11 is not limited. For example, the pusher driving member 11 can also be a motor, etc. And the type of the first elastic member 14 is not limited either. For example, the first elastic member 14 can also be an elastic rubber member.

[0051] The pusher plate 13 has a pusher plane 131, and the pusher plate 13 contacts the battery 200 through the pusher plane 131 to push the battery 200 into the rotary positioning device 20. Optionally, the pusher driving member 11 can push the pusher plate 13 to move along a straight line through the mounting plate 12, and the pusher plane 131 intersects with this straight line, specifically perpendicular. In some specific embodiments, the battery 200 is sheet-shaped, and the pusher plate 13 pushes one end face in the length direction of the battery 200 through the pusher plane 131. At this time, the pusher plane 131 is parallel to this end face, and the extending direction of the straight line is parallel to the length direction of the battery 200.

[0052] The pusher device 10 further includes a resisting portion 15, and the resisting portion 15 is disposed on the side of the mounting plate 12 facing the pusher plate 13. When the pusher plate 13 pushes the battery 200 through the pushing plane 131, the first elastic member 14 is compressed by the force, so that the surface of the pusher plate 13 facing the mounting plate 12 contacts the resisting portion 15. When the pusher plate 13 is subjected to a force, it can slide relative to the mounting plate 12 in a plane parallel to the pushing plane 131 under the action of the first elastic member 14 and the resisting portion 15( Figure 5 The green dashed line in represents the position where the pusher plate 13 can slide within the plane).

[0053] For the above-mentioned pusher device 10, when the pusher plate 13 pushes the battery 200 through the pushing plane 131 and the battery 200 is offset, resulting in an inclination between the end face and the positioning surface 31 of the end face positioning device 30. When the pusher plate 13 continues to push the battery 200, the battery 200 is restricted by the positioning surface 31 and will apply a force to the pusher plate 13, and the first elastic member 14 elastically deforms. At this time, the pusher plate 13 slides relative to the mounting plate 12 in a plane parallel to the pushing plane 131 under the elastic deformation of the first elastic member 14 and the resisting action of the resisting portion 15, and there is a slight movement between the pushing plane 131 and the end face of the battery 200, compensating for the positioning error between the end face of the battery 200 and the positioning surface 31, so that the end face of the battery 200 is completely attached to the positioning surface 31, finally meeting the requirement of end face consistency. Since the end face positioning of the battery 200 is consistent, when the rotary positioning device 20 performs secondary positioning on the battery 200, the battery 200 will not slide, and it is not easy to cause scratches on the end face of the battery 200. At the same time, during welding, the welding track will not shift, and the pole column will not be burned, and the scrap rate of the battery 200 is greatly reduced.

[0054] In some embodiments, the resisting portion 15 is a rolling member disposed on the mounting plate 12. When the pusher plate 13 is subjected to a force, the rolling member rolls relative to the pusher plate 13 and the mounting plate 12, so that the pusher plate 13 slides relative to the mounting plate 12. Using the rolling member as the resisting portion 15 can reduce the friction between the pusher plate 13 and the resisting portion 15, facilitating the sliding of the pusher plate 13 relative to the mounting plate 12.

[0055] It can be imagined that in some other embodiments, the resisting portion 15 can also be arranged in other ways. For example, the end face of the mounting plate 12 facing the pusher plate 13 directly forms the resisting portion 15, or a boss is provided on the end face of the mounting plate 12 facing the pusher plate 13, and the boss forms the resisting portion 15.

[0056] In some specific embodiments, continue to refer to Figure 5The rolling element includes a plurality of balls 151, which are installed at intervals on the mounting plate 12. In this way, when the push plate 13 pushes the battery 200, the first elastic member 14 is compressed, and the push plate 13 can contact the plurality of balls 151 and slide relative to the mounting plate 12 under the action of the plurality of balls 151.

[0057] It should be noted that the plurality of balls 151 are located on the same plane, so that the pusher plate 13 slides in a plane parallel to the pusher plane 131 under the action of the plurality of balls 151 .

[0058] Optionally, a first mounting groove is provided on the mounting plate 12, the ball 151 corresponds to the first mounting groove one by one, and part of the ball 151 is embedded in the first mounting groove to ensure that the other part of the ball 151 contacts the push plate 13, so that the push plate 13 slides relative to the mounting plate 12 under the action of the ball 151.

[0059] In some other embodiments, multiple balls 151 may be installed in one first installation groove, which is not limited here.

[0060] Further, see Figure 4 and Figure 5 The push plate 13 and the mounting plate 12 are both provided with second mounting grooves 16, and the two ends of the first elastic member 14 are respectively placed in the two second mounting grooves 16 to facilitate the fixation of the first elastic member 14 to the push plate 13 and the mounting plate 12. Of course, the second mounting grooves 16 can also be omitted, and the first elastic member 14 can also be connected to the push plate 13 and the mounting plate 12 in other ways, which are not limited here.

[0061] In some embodiments, see Figure 3 and Figure 4 The pushing device 10 further includes a limiting plate 17, which is connected to the mounting plate 12 and defines an accommodating cavity 18. The accommodating cavity 18 has an opening 181 formed on the limiting plate 17. The pushing plate 13 includes a push plate 132 and a positioning plate 133 that are connected to each other. The push plate 132, the first elastic member 14, and the stopper 15 are all located in the accommodating cavity 18. The push plate 132 is abutted against the limiting plate 17 under the action of the first elastic member 14. The positioning plate 133 extends out of the accommodating cavity 18 through the opening 181. The pushing plane 131 is located on the portion of the positioning plate 133 that extends out of the accommodating cavity 18. With this arrangement, when the pushing device 10 pushes a battery 200 into the rotation positioning device 20 and returns to the initial position to push the next battery 200, since the push plate 132 and the first elastic member 14 are both limited in the accommodating cavity 18, the pushing plate 13 will not be unable to return to the initial position (if there is no limitation of the limiting plate 17, the pushing plate 13 is prone to shaking due to the elasticity of the first elastic member 14, resulting in it being unable to return to the initial position).

[0062] Further, see Figure 4 and Figure 5 The end of the positioning plate 133 that connects to the push plate 132 has a stepped portion. The stepped portion and the push plate 132 form a limiting groove 19. The limiting plate 17 extends into the limiting groove 19 to limit the push plate 132 from extending out of the accommodating cavity 18. This arrangement not only prevents the push plate 132 from escaping the accommodating cavity 18; at the same time, when the push plate 13 pushes the battery 200 through the positioning plate 133, the limiting plate 17 can also limit the position of the positioning plate 133, preventing the push plate 132 from over-pressing the stopper 15.

[0063] Furthermore, in the pushing direction of the pushing device 100 pushing the battery 200, a first gap is formed between the push plate 132 and the ball bearing 151, so that when the positioning plate 133 pushes the battery 200, a second gap is formed between the push plate 132 and the limiting plate 17. Because the positioning plate 133 forms the second gap with the limiting plate 17 when pushing the battery 200, when the push plate 13 moves relative to the mounting plate 12, there is no friction between the limiting plate 17 and the push plate 13, and the limiting plate 17 does not interfere with the movement of the push plate 13.

[0064] In some embodiments, the positioning plate 133 is detachably mounted on the push plate 132. This facilitates replacement of the positioning plate 133 to accommodate different battery models 200. Optionally, the positioning plate 133 and the push plate 132 are detachably secured by screws. Of course, in other embodiments, the positioning plate 133 can also be detachably connected to the push plate 132 by other means, such as by a snap-fit connection.

[0065] Further, see Figure 4 The middle portion of the surface of the positioning plate 133 facing away from the push plate 132 is recessed, and the pushing plane 131 is formed on the outer portion of the push plate 13, and the outer portion is arranged outside the middle portion. That is, the positioning plate 133 includes a main body 1331 and a push arm 1332. The main body 1331 is connected to the push plate 132, and the push arm 1332 is connected to the periphery of the main body 1331 away from the push plate 132 and protrudes from the main body 1331. The pushing plane 131 is formed on the push arm 1332. In this way, when pushing the battery 200, the middle portion of the positioning plate 133 does not contact the battery 200, which enables the pushing plane 131 formed on the outer portion to better fit the end face of the battery 200, ensuring the smoothness of the pushing.

[0066] Specifically, the positioning plate 133 is made of non-metallic material to ensure that the positioning plate 133 does not scratch the surface of the battery 200 when in contact with the battery 200 .

[0067] In some embodiments, see Figure 6 and Figure 7, the rotation positioning device 20 includes a turntable 21. The turntable 21 is provided with a through hole 211 axially ( Figure 7 in the left-right direction in []. The pusher device 10 and the end face positioning device 30 are located at both ends of the rotation positioning device 20 in the axial direction of the turntable 21. The pusher device 10 can push the battery 200 axially ( Figure 7 the direction indicated by the arrow in [] represents the direction in which the pusher device 10 pushes the battery 200) into the through hole 211.

[0068] The rotation positioning device 20 further includes a clamping mechanism 22. The clamping mechanism 22 includes a first clamping component 221 and a second clamping component 222. Both the first clamping component 221 and the second clamping component 222 are mounted on the turntable 21. The first clamping component 221 and the second clamping component 222 clamp the battery 200 along the first radial direction and the second radial direction of the turntable 21 respectively. The turntable 21 can be controlled to rotate around an axis. Specifically, this axis is the central axis of the turntable 21. The turntable 21 can rotate around the central axis to drive the first clamping component 221 and the second clamping component 222 to rotate, thereby driving the clamped battery 200 to rotate, so as to facilitate the welding device to weld all circumferential parts of the battery 200.

[0069] Among them, the first radial direction intersects with the second radial direction. Specifically, the first radial direction is perpendicular to the second radial direction. The first radial direction is Figure 6 the up-down direction in [], and the second direction is Figure 6 the left-right direction in []. When the battery 200 is sheet-shaped, the axial direction of the turntable 21 is parallel to the length direction of the battery 200, the first radial direction is parallel to the thickness direction of the battery 200, and the second radial direction is parallel to the width direction of the battery 200. The battery 200 can be conveyed along the length direction to the through hole 211. The first clamping component 221 and the second clamping component 222 clamp the battery 200 from both sides of the thickness direction and the width direction of the battery 200 respectively. In some other embodiments, according to the different shapes of the battery 200, the relationships between the axial direction, the first radial direction and the second radial direction and the directions of the battery 200 itself will change accordingly.

[0070] Continue to refer to Figure 6 and Figure 7, both the first clamping assembly 221 and the second clamping assembly 222 include correspondingly arranged first positioning blocks 2211 and second positioning blocks 2212, and both the first positioning blocks 2211 and the second positioning blocks 2212 are installed on the turntable 21. All the first positioning blocks 2211 and all the second positioning blocks 2212 axially penetrate through the through hole 211 on the turntable 21 and both ends protrude out of the turntable 21. Among them, the second positioning blocks 2212 of both the first clamping assembly 221 and the second clamping assembly 222 are movably installed on the turntable 21 to cooperate with the first positioning blocks 2211 to clamp the battery 200. Specifically, the second positioning block 2212 of the first clamping assembly 221 is movably installed on the turntable 21 along the first radial direction to approach or move away from its corresponding first positioning block 2211, so as to clamp or loosen the battery 200 axially conveyed into the through hole 211 along the first radial direction. The second positioning block 2212 of the second clamping assembly 222 is movably installed on the turntable 21 along the second radial direction to approach or move away from its corresponding first positioning block 2211, so as to clamp or loosen the battery 200 axially conveyed into the through hole 211 along the second radial direction.

[0071] In the above setting, before the battery 200 is conveyed into the through hole 211, both of the two second positioning blocks 2212 are away from the first positioning blocks 2211. After the battery 200 is pushed into the through hole 211 by the pusher device 100, the two second positioning blocks 2212 move relative to the turntable 21 along the first radial direction and the second radial direction respectively, so as to cooperate with their corresponding first positioning blocks 2211 to clamp and position the battery 200 from two different directions. After the battery 200 is clamped by the clamping assembly, the turntable 21 drives the battery 200 to rotate, and the welding device can weld the battery 200, for example, the welding device can weld the end cap to the housing of the battery 200.

[0072] With the above rotation positioning device 20, under the combined action of the first clamping assembly 221 and the second clamping assembly 222 of a set of clamping mechanisms, the battery 200 can be clamped from two different directions. Compared with the prior art method of clamping the battery 200 by two sets of clamping mechanisms (the two sets of clamping mechanisms are respectively located at both ends of the axial direction of the turntable 21), the structural setting of the rotation positioning device 20 is simplified. At the same time, since the first clamping assembly 221 and the second clamping assembly 222 respectively move relative to their corresponding first positioning blocks 2211 through their respective second positioning blocks 2212 to clamp the battery 200, there is no problem of out-of-synchronization in the movement between the second positioning blocks 2212 of the front and rear two sets of clamping mechanisms in the prior art, ensuring the accuracy of positioning. And, since each first positioning block 2211 and second positioning block 2212 penetrate through the through hole 211 and both ends protrude out of the turntable 21, the dimensions of each positioning block in the axial direction of the turntable 21 are ensured, increasing the contact area between the positioning block and the battery 200 and ensuring the clamping and positioning effect.

[0073] It should be noted here that, compared with the prior art, the above-mentioned rotary positioning device 20 reduces the number of clamping mechanisms 22, greatly simplifies the debugging steps, and increases the convenience of debugging.

[0074] In some embodiments, both the first positioning block 2211 and the second positioning block 2212 are detachably connected to the turntable 21. With this arrangement, when the positioning block wears out, it is convenient to replace it with a new one. At the same time, since the rotary positioning device 20 in the present application only includes a set of clamping mechanisms, compared with the prior art where there are two sets of clamping mechanisms (two sets of clamping mechanisms require two sets of front and rear first clamping components 221 and second clamping components 222), the number of positioning blocks is reduced, facilitating the quick replacement of the positioning blocks.

[0075] Continue to refer to Figure 7 and Figure 8 , the rotary positioning device 20 further includes a mounting base 23 and a rotary driving member 24. The turntable 21 is mounted on the mounting base 23 and connected to the rotary driving member 24. The rotary driving member 24 is used to drive the turntable 21 to rotate, so as to drive the first clamping component 221 and the second clamping component 222 to rotate. Optionally, the rotary driving member 24 is a motor or a cylinder, etc.

[0076] Refer to Figure 7 , Figure 9 and Figure 10 , the first clamping component 221 and / or the second clamping component 222 further includes a first guiding member 2213 and a second guiding member 2214. First mounting sides 212 and second mounting sides 213 are respectively formed on both end faces of the turntable 21 along the axial direction. The first guiding member 2213 is disposed on the first mounting side 212, and the second guiding member 2214 is disposed on the second mounting side 213. The two ends of the second positioning block 2212 protruding from the turntable 21 are respectively slidably connected to the turntable 21 along the radial direction through the first guiding member 2213 and the second guiding member 2214, and the first guiding member 2213 and the second guiding member 2214 cooperate to guide the second positioning block 2212 along the radial direction. In this way, under the combined guiding action of the first guiding member 2213 and the second guiding member 2214, it can be ensured that both ends of the second positioning block 2212 in the axial direction are in large-area contact with the battery 200, ensuring the clamping effect.

[0077] In some specific embodiments, both the first clamping assembly 221 and the second clamping assembly 222 include a first guide member 2213 and a second guide member 2214. In this way, the second positioning blocks 2212 of the first clamping assembly 221 and the second clamping assembly 222 move radially under the combined action of the first guide member 2213 and the second guide member 2214, ensuring that both ends of the second positioning blocks 2212 of the first clamping assembly 221 and the second clamping assembly 222 are in large-area contact with the battery 200 in the axial direction, thus ensuring the clamping effect. In other specific embodiments, it is also possible to set that one of the first clamping assembly 221 and the second clamping assembly 222 includes a first guide member 2213 and a second guide member 2214, while the other only has one guide member or no guide member is provided, which is not limited herein.

[0078] Optionally, both the first guide member 2213 and / or the second guide member 2214 include a first slide rail and a first slider. The first slide rail extends radially. One of the first slide rail and the first slider is connected to the turntable 21, and the other is connected to the second positioning block 2212. The first slider is slidably engaged with the first slide rail. The second positioning block 2212 moves radially relative to the turntable 21 under the cooperation of the first slider and the first slide rail.

[0079] It should be noted that in some specific embodiments, it is set that both the first guide member 2213 and the second guide member 2214 include a slide rail and a slider. In other specific embodiments, it is also possible to set that one of the first guide member 2213 and the second guide member 2214 includes a first slide rail and a first slider, while the other guide member adopts other settings.

[0080] Continue to refer to Figure 7 , the first clamping assembly 221 and / or the second clamping assembly 222 further include a limiting member 2215 and a second elastic member 2216. The limiting member 2215 is installed on the turntable 21, and the second elastic member 2216 is arranged between the second positioning block 2212 and the limiting member 2215. When the second positioning block 2212 moves radially away from the first positioning block 2211, the second elastic member 2216 is compressed to store energy. The second positioning block 2212 can move radially closer to the first positioning block 2211 under the action of the second elastic member 2216. Since the second positioning block 2212 is far from the first positioning block 2211 before the battery 200 is pushed into the through hole 211, at this time the second elastic member 2216 is compressed to store energy. And when the battery 200 is pushed into the through hole 211, the second positioning block 2212 can approach the first positioning block 2211 under the elastic force of the second elastic member 2216 to clamp the battery 200, avoiding the need to provide another structure for the reset of the second positioning block 2212, making the structure of the rotary positioning device 20 simple. Optionally, the second elastic member 2216 is a spring

[0081] It should be noted here that in some specific embodiments, both the first clamping assembly 221 and the second clamping assembly 222 include a limiting member 2215 and a second elastic member 2216. In some other specific embodiments, it is also possible to set that one of the first clamping assembly 221 and the second clamping assembly 222 includes a limiting member 2215 and a second elastic member 2216, while the other omits the second elastic member 2216 and the limiting member 2215.

[0082] Continue to refer to Figure 7 , the clamping mechanism 22 further includes a clamping driving member 223. At least one second positioning block 2212 is connected to the clamping driving member 223. The clamping driving member 223 is used to drive the second positioning block 2212 to approach and / or move away from the first positioning block 2211 in the radial direction. In some specific embodiments, both the first clamping assembly 221 and the second clamping assembly 222 include a second elastic member 2216 and a limiting member 2215. The clamping driving member 223 is used to drive the second positioning block 2212 to move away from the first positioning block 2211 in the radial direction, and the second elastic member 2216 causes the second positioning block 2212 to approach the first positioning block 2211 in the radial direction.

[0083] It can be imagined that in some other embodiments, when the first clamping assembly 221 and / or the second clamping assembly 222 omit the limiting member 2215 and the second elastic member 2216, the clamping driving member 223 can also drive the second positioning block 2212 to approach the first positioning block 2211 in the radial direction. In some other embodiments, when the first clamping assembly 221 and / or the second clamping assembly 222 omit the limiting member 2215 and the second elastic member 2216, the clamping driving member 223 can also drive the second positioning block 2212 to approach and move away from the first positioning block 2211 in the radial direction, which is not limited herein.

[0084] In some specific embodiments, one clamping driving member 223 is correspondingly provided for one second positioning block 2212. The clamping mechanism 22 further includes a first hook 224 and a second hook 225. The first hook 224 is connected to the second positioning block 2212, and the second hook 225 is connected to the clamping driving member 223. The first hook 224 and the second hook 225 pull each other. The clamping driving member 223 can drive the second positioning block 2212 to move away from the first positioning block 2211 in the radial direction through the second hook 225 and the first hook 224, and the second elastic member 2216 is compressed to store energy. The second positioning block 2212 can approach the first positioning block 2211 in the radial direction under the action of the second elastic member 2216. With such a setting, the clamping driving member 223 can drive the second positioning block 2212 away from the first positioning block 2211, so as to facilitate the pushing device 10 to push the battery 200 into the through hole 211; and after the battery 200 is pushed into the through hole 211, the second positioning block 2212 can cooperate with the first positioning block 2211 to clamp the battery 200 under the reset action of the second elastic member 2216, with a simple and reliable structure.

[0085] It should be noted here that when the second positioning block 2212 moves radially closer to the first positioning block 2211 under the action of the second elastic member 2216, the first hook 224 and the second hook 225 are separated, and the movement of the second positioning block 2212 is not restricted. Optionally, the clamping driving member 223 is a cylinder ( Figure 6 and Figure 7 the arrow in represents the telescopic direction of the cylinder piston rod). When the second positioning block 2212 needs to move away from the first positioning block 2211 to avoid the battery 200, the cylinder drives the second hook 225 to move, and then drives the second positioning block 2212 to move through the first hook 224. When the second positioning block 2212 needs to move closer to the first positioning block 2211 to clamp the battery 200, the cylinder drives the second hook 225 to move in the reverse direction, so that the second hook 225 is in a position where it does not interfere with the second positioning block 2212, and the second positioning block 2212 moves closer to the first positioning block 2211 under the action of the second elastic member 2216 to clamp the battery 200.

[0086] In some embodiments, continue to refer to Figure 6 and Figure 7 , the clamping driving member 223 is arranged on the mounting seat 23. At this time, the clamping driving member 223 does not rotate with the rotation of the turntable 21, that is, the turntable 21 does not drive the clamping driving member 223 to rotate, and the number of rotating components is reduced, ensuring the stability of the turntable 21 during rotation. In other embodiments, the clamping driving member 223 can also be arranged on the turntable 21 and rotate with the rotation of the turntable 21, which is not limited here.

[0087] In some embodiments, the position of at least one first positioning block 2211 on the turntable 21 is adjustable to adjust the radial distance between the first positioning block 2211 and the corresponding second positioning block 2212. When the first positioning block 2211 and the second positioning block 2212 clamp and position the battery 200, if the clamping degree is too large, it will cause damage to the battery 200. If the clamping degree is too small, there will be a problem of insufficient clamping. By finely adjusting the position of the first positioning block 2211 on the turntable 21, the distance between the second positioning block 2212 and the first positioning block 2211 can be changed, which can accommodate the error of the battery 200, so as to clamp the battery 200 with an appropriate clamping degree, reducing the damage to the battery 200 while ensuring the clamping of the battery 200.

[0088] Specifically, the positions of the first positioning blocks 2211 of the first clamping assembly 221 and the second clamping assembly 222 on the turntable 21 are adjustable to adjust the radial distances between the two first positioning blocks 2211 and the corresponding second positioning blocks 2212. Of course, in some other embodiments, it can also be set that only the position of the first positioning block 2211 of one clamping assembly on the turntable 21 is adjustable, which is not limited here either.

[0089] Continue to refer to Figure 9 , the first clamping assembly 221 and / or the second clamping assembly 222 includes an adjusting screw 2217. The adjusting screw 2217 connects the turntable 21 and the first positioning block 2211. The adjusting screw 2217 is operably rotated to adjust the position of the first positioning block 2211 on the turntable 21. Optionally, the adjusting screw 2217 is rotatably connected to the turntable 21 and is screwed to the first positioning block 2211. When the adjusting screw 2217 is rotated, the first positioning block 2211 can move relative to the turntable 21 and change the distance from the corresponding second positioning block 2212.

[0090] [[ID=[6]]Refer to Figure 8 and Figure 11 , the first clamping assembly 221 and / or the second clamping assembly 222 further includes a third guiding member 2218. The adjusting screw 2217 is disposed on the ground mounting side, and the third guiding member 2218 is disposed on the second mounting side 213. When the position of the first positioning block 2211 and the turntable 21 is adjusted by the adjusting screw 2217, the third guiding member 2218 guides the first positioning block 2211 radially to prevent the first positioning block 2211 from deviating.

[0091] In some specific embodiments, both the first clamping assembly 221 and the second clamping assembly 222 include the third guiding member 2218. Thus, when the position of the first positioning block 2211 of the first clamping assembly 221 and the second clamping assembly 222 on the turntable 21 is adjusted, the first positioning block 2211 is prevented from deviating under the action of the third guiding member 2218. In some other specific embodiments, it is also possible to provide that one of the first clamping assembly 221 and the second clamping assembly 222 includes the third guiding member 2218, while the other does not include the guiding member, which is not limited herein.

[0092] Optionally, the third guiding member 2218 and / or the fourth guiding member both include a second slide rail and a second slider. The second slide rail extends radially. One of the second slide rail and the second slider is connected to the turntable 21, and the other is connected to the first positioning block 2211. The second slider cooperates with the second slide rail. The first positioning block 2211 adjusts its position on the turntable 21 under the guiding action of the second slide rail and the second slider.

[0093] Preferably, the limiting member 2215, the second elastic member 2216 and the adjusting screw 2217 are all disposed on the first mounting side 212. Such a setting can enable multiple components of the first clamping assembly 221 and the second clamping assembly 222 to be concentrated on the first mounting side 212, ensuring the structural compactness of the rotary positioning device 20.

[0094] Refer to Figure 2, Another embodiment of the present application further provides a positioning system 100 included in the above welding device. Since the above welding device has beneficial effects, the positioning system 100 belonging to the above welding device has the same beneficial effects, which will not be elaborated in detail here.

[0095] Continue to refer to Figures 3 - 5 , Another embodiment of the present application further provides a feeding device 10 included in the above positioning system 100. Since the above positioning system 100 has beneficial effects, the feeding device 10 belonging to the above positioning system 100 has the same beneficial effects, which will not be elaborated in detail here.

[0096] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0097] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
