[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] This application provides a conveying device and welding equipment to solve the technical problem of low manufacturing efficiency of power batteries.

[0053] In the embodiments of this application, such as Figure 1 As shown, the conveying device includes a first guide member 1, a second guide member 2, a support assembly 3, and a conveying assembly 4. The length directions of both the first guide member 1 and the second guide member 2 are parallel to a first direction, and the first guide member 1 and the second guide member 2 are spaced apart along a second direction. A support assembly 3 is provided on both the first guide member 1 and the second guide member 2, and the support assembly 3 is used to support the product. A conveying assembly 4 is slidably mounted on both the first guide member 1 and the second guide member 2, and the conveying assembly 4 slides along the first direction, used to load the product onto the support assembly 3 or unload the product from the support assembly 3. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0054] In this embodiment, the product can be a tray on which battery cells can be placed. When the tray is placed on the support assembly 3, the busbar can be welded to the terminal of the battery cell using a laser beam. Both the first guide 1 and the second guide 2 can be fixed to the ground.

[0055] The space between the first guide 1 and the second guide 2 is used for the passage of an AGV (Automated Guided Vehicle) trolley, which transports products. When the AGV trolley transports the product between the first guide 1 and the second guide 2, the feeding assembly 4 picks up the product from the AGV trolley and slides along a first direction to deliver the product to the support assembly 3. The feeding assembly 4 then places the product on the support assembly 3 so that the laser beam can perform welding operations on the battery cells inside the product.

[0056] Alternatively, the feeding assembly 4 picks up the product from the support assembly 3, and then slides along a first direction to transport the product to the unloading position between the first guide 1 and the second guide 2. The feeding assembly 4 then places the product onto an AGV trolley, which transports the product to the next position.

[0057] In this embodiment, the first guide 1 and the second guide 2 are spaced apart to allow the AGV trolley used for transporting products to pass through. The support component 3 is disposed on the first guide 1 or the second guide 2 to support the product and facilitate welding of the battery cells inside the product. The material conveying component 4 is slidably disposed on the first guide 1 or the second guide 2 along the first direction to pick up the product from the AGV trolley and convey it along the first direction to the support component 3, or to pick up the product on the support component 3 and convey it along the first direction to the AGV trolley. By having the material conveying component 4 replace the AGV trolley in transporting products, the time for transporting products can be reduced, the welding efficiency of the battery cells inside the product can be improved, thereby improving the manufacturing efficiency of the power battery.

[0058] In one embodiment, such as Figure 1 As shown, two sets of conveying components 4 are slidably mounted on both the first guide 1 and the second guide 2, and the two sets of conveying components 4 are spaced apart along the first direction. When the AGV trolley transports the product to the loading position between the first guide 1 and the second guide 2, one set of conveying components 4 is used to grab the product from the AGV trolley at the loading position and transport it along the first direction to the support component 3. After the battery cells inside the product on the support component 3 are welded, the other set of conveying components 4 is used to grab the product on the support component 3 and transport it along the first direction to the AGV trolley at the unloading position, and the AGV trolley transports the product to the next position.

[0059] After the AGV (Automated Guided Vehicle) transports the product to the loading position, the conveying component 4 picks up the product from the AGV, and then the AGV continues to move along the first direction between the first guide 1 and the second guide 2. Since the AGV's moving speed is slower than the product transport speed of the conveying component 4, the AGV moves to the unloading position just as the product is being transported by the conveying component 4 to the support component 3, where the battery cells are welded, and then transported to the unloading position by the conveying component 4. In other words, the sum of the time it takes for the conveying component 4 to transport the product from the loading position to the support component 3, the time for welding the battery cells on the support component 3, and the time it takes for the conveying component 4 to transport the product from the support component 3 to the unloading position is equal to the time it takes for the AGV to move from the loading position to the unloading position. Therefore, by having the conveying component 4 replace the AGV in transporting products, the welding cycle of the battery cells can be increased, thereby improving the manufacturing efficiency of the power battery.

[0060] Understandably, the feeding component 4 on the first guide 1 corresponds one-to-one with the feeding component 4 on the second guide 2. The feeding component 4 on the first guide 1 and the corresponding feeding component 4 on the second guide 2 move synchronously and are used to lift and transport the same product.

[0061] In one embodiment, such as Figure 1 and Figure 4 As shown, the material conveying assembly 4 includes a sliding unit 41, a first driving unit 42, and a lifting member 43. The sliding unit 41 is slidably disposed on the first guide member 1 or the second guide member 2 along a first direction. The first driving unit 42 is disposed on the sliding unit 41, and the lifting member 43 is disposed at the output end of the first driving unit 42. The first driving unit 42 is used to drive the lifting member 43 to rise and fall.

[0062] The first drive unit 42 is used to drive the lifting member 43 to rise and fall, so as to lift the bottom of the product by the lifting member 43, thereby separating the product from the AGV trolley or support assembly 3. After the lifting member 43 lifts the product, the sliding unit 41 can drive the lifting member 43 to slide along the first direction, thereby conveying the product along the first direction.

[0063] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the sliding unit 41 includes a sliding seat 411, a driver 412, and a gear. The sliding seat 411 is slidably mounted on the first guide member 1 or the second guide member 2, and the first drive unit 42 is mounted on the sliding seat 411. The driver 412 is mounted on the sliding seat 411, and the gear is mounted on the output end of the driver 412. The driver 412 is used to drive the gear to rotate. The conveying device also includes a rack 5, which is mounted on the first guide member 1 or the second guide member 2. The length direction of the rack 5 is parallel to the first direction, and the gear meshes with the rack 5.

[0064] Since the gear meshes with the rack 5, when the driver 412 drives the gear to rotate, the gear will drive the sliding seat 411 to slide in the first direction through the driver 412, thereby facilitating the transport of products.

[0065] In one embodiment, such as Figure 4 and Figure 5 As shown, the material conveying assembly 4 also includes a second drive unit 44 and a first limiting member 45. The second drive unit 44 is disposed on the lifting member 43. The lifting member 43 is provided with a first guide hole 431, the length direction of which is parallel to the vertical direction. The first limiting member 45 is disposed within the first guide hole 431 and is located at the output end of the second drive unit 44. The second drive unit 44 is used to drive the first limiting member 45 to rise and fall, so that the first limiting member 45 extends out of the upper surface of the lifting member 43.

[0066] When the first drive unit 42 drives the lifting member 43 to lift the product, the second drive unit 44 drives the first limiting member 45 to rise and fall, so that the first limiting member 45 extends out of the upper surface of the lifting member 43 from the first guide hole 431, thereby allowing the first limiting member 45 to be inserted into the limiting hole at the bottom of the product, so as to position the product through the first limiting member 45.

[0067] In one embodiment, such as Figure 4 and Figure 5 As shown, the feeding assembly 4 also includes a fixing member 46, an adjusting member 47, and a second limiting member 48. The fixing member 46 is disposed on the lifting member 43. The adjusting member 47 is disposed on the fixing member 46, and the second limiting member 48 is disposed on the adjusting member 47. The adjusting member 47 can adjust the position of the second limiting member 48 in a second direction so that the second limiting member 48 limits the product.

[0068] The adjusting member 47 can adjust the position of the second limiting member 48 in the second direction so that it clamps the product along the second direction with the corresponding second limiting member 48 on another guide member, thereby limiting the product in the second direction. By adjusting the position of the second limiting member 48 along the second direction through the adjusting member 47, products of different widths can be accommodated, thereby improving the compatibility of the conveying device.

[0069] In this embodiment, the adjusting member 47 can be a screw. The adjusting member 47 is threadedly connected to the fixing member 46 and fixedly connected to the second limiting member 48, so that the position of the second limiting member 48 in the second direction can be adjusted by rotating the adjusting member 47. When the adjusting member 47 is a screw, the adjusting member 47 can also be threadedly connected to the second limiting member 48, so that the adjusting member 47 and the second limiting member 48 form a lead screw structure, thereby adjusting the position of the second limiting member 48 in the second direction.

[0070] In one embodiment, such as Figure 1 and Figure 3 As shown, the support assembly 3 includes a support frame 31, a third drive unit 32, and a third limiting member 33. The support frame 31 is disposed on either the first guide member 1 or the second guide member 2. A second guide hole 311 is provided on the support frame 31, and the length direction of the second guide hole 311 is parallel to the vertical direction. The third drive unit 32 is disposed on the support frame 31, and the third limiting member 33 is disposed within the second guide hole 311, at the output end of the third drive unit 32. The third drive unit 32 is used to drive the third limiting member 33 to rise and fall, so that the third limiting member 33 extends beyond the upper surface of the support frame 31. The support frame 31 is used to support the product.

[0071] When the support frame 31 supports the product, the third drive unit 32 drives the third limiting member 33 to rise and fall, so that the third limiting member 33 extends out of the second guide hole 311 from the upper surface of the support frame 31, thereby allowing the third limiting member 33 to be inserted into the limiting hole at the bottom of the product, so as to position the product through the third limiting member 33.

[0072] In one embodiment, such as Figure 1 and Figure 3 As shown, the support assembly 3 also includes a mounting base 34 and a rolling ball 35. The mounting base 34 is disposed on the support frame 31. The rolling ball 35 is rotatably disposed on the mounting base 34, and the highest point of the rolling ball 35 is higher than the upper surface of the support frame 31.

[0073] The highest point of the rolling ball 35 is higher than the upper surface of the support frame 31, so that the product can be supported by the rolling ball 35. During the process of positioning the product by the third limiting member 33, the product may move slightly relative to the support frame 31. Supporting the product by the rolling ball 35 can reduce friction and facilitate product movement.

[0074] Understandably, the top of the third limiting member 33 can be configured as an inverted cone shape that gradually tapers from bottom to top, so as to facilitate the third limiting member 33 sliding into the limiting hole at the bottom of the product for positioning. During the process of the third limiting member 33 sliding into the limiting hole at the bottom of the product, the product will undergo a small displacement relative to the support frame 31.

[0075] In one embodiment, such as Figure 1 As shown, the conveying device also includes a rotating component 6. The rotating component 6 is provided on the side of the first guide component 1 facing the second guide component 2 and on the side of the second guide component 2 facing the first guide component 1. The rotation center line of the rotating component 6 is parallel to the vertical direction.

[0076] The rotating component 6 is used to abut against the side of the AGV trolley along the second direction, thereby limiting the position of the AGV trolley in the second direction. During the movement of the AGV trolley along the first direction, the rotating component 6 can rotate, thus reducing friction and facilitating the movement of the AGV trolley. The rotating component 6 can be a bearing.

[0077] Furthermore, this application also provides a welding device, which includes a welding head and a conveying device. The specific structure of the conveying device is as described in the above embodiments. Since the welding device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.
