[0037] The linkage adjustment device provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0038] Referring to Figures 1 to 3 , the embodiments of the present application provide a linkage adjustment device, including an operation component 1, a first movable member 2, a second movable member 3, a first fixing member 4, a second fixing member 5, and a base component 6; the operation component 1 is connected to the first movable member 2 and the second movable member 3, the first movable member 2 is rotatably connected to the first fixing member 4, a first sliding groove 31 is formed in the second movable member 3, the first sliding groove 31 is arc-shaped, the second movable member 3 is slidably connected to the second fixing member 5 through the first sliding groove 31, both the first fixing member 4 and the second fixing member 5 are fixedly connected to the base component 6, and the operation component 1 is used for battery dispensing or spot welding.

[0039] Specifically, as Figures 1 to 3As shown in the figure, an embodiment of the present application provides a linkage adjustment device for use in battery dispensing or welding processes. The operating component 1 can be a spot welding head or a dispensing head. The front part of the operating component 1 is connected to the front part of the first movable member 2, and the rear part is connected to the front part of the second movable member 3. The first movable member 2 and the second movable member 3 can be plate-shaped, column-shaped, or rod-shaped. The first movable member 2 is also called the front support plate or the front rotating arm, and the second movable member 3 is also called the rear support plate or the rear rotating arm. The rear part of the first movable member 2 is rotatably connected to the first fixed member 4, and the rotation axis is along the X-axis. A first chute 31 is provided at the rear part of the second movable member 3. The first chute 31 is arc-shaped, and the center of curvature of the arc passes through the rotating shaft between the first movable member 2 and the first fixed member 4. The second movable member 3 is slidably connected to the second fixed member 5 through the first chute 31. That is, during the movement of the second movable member 3, since the second fixed member 5 is stationary, the second fixed member 5 slides along the first chute 31 relative to the second movable member 3. The first fixed member 4 is also called the front rotating shaft seat, and the second fixed member 5 is also called the rear rotating shaft seat. The lower parts of the first fixed member 4 and the second fixed member 5 are fixed to the base assembly 6.

[0040] In some embodiments, when the operator rotates the first movable member 2 so that the first movable member 2 rotates relative to the first fixed member 4 about the X-axis, the operating component 1 moves under the drive of the first movable member 2, and its angle changes. At the same time, the operating component 1 drives the second movable member 3 to rotate about the rotating shaft between the first movable member 2 and the first fixed member 4, so that the second movable member 3 slides along the first chute 31 relative to the second fixed member 5. The arc-shaped first chute 31, on the one hand, provides a route for the second movable member 3 to rotate relative to the rotating shaft between the first movable member 2 and the first fixed member 4, and on the other hand, limits and restricts the second movable member from slipping off. The operating component 1 deflects and its angle changes under the drive of the first movable member 2 and the second movable member 3, thus realizing the function of freely adjusting the position of the dispensing head or the spot welding head, and can meet the dispensing or spot welding requirements of batteries of different specifications and sizes.

[0041] By using the linkage adjustment device provided by the embodiment of the present application, when the operator rotates the first movable member, the second movable member slides along the second chute relative to the second fixed member. Under the drive of the first movable member and the second movable member, both the front and rear ends of the operating component including the dispensing head or the spot welding head deflect and the angle changes, realizing the function of freely adjusting the position of the dispensing head or the spot welding head, meeting the dispensing or spot welding requirements of batteries of different specifications and sizes, improving the compatibility of the device, and being applicable to the processing and manufacturing of different products.

[0042] Optionally, referring to Figure 1, a second sliding groove 32 is further formed on the second movable member 3, and a third sliding groove 21 is formed on the first movable member 2; the second sliding groove 32 and the third sliding groove 21 extend in the same direction, and the operating assembly 1 is slidably connected to the second movable member 3 through the second sliding groove 32, and the operating assembly 1 is slidably connected to the first movable member 2 through the third sliding groove 21.

[0043] Specifically, as Figure 1 shown, the first sliding groove 31 is formed at one end of the second movable member 3 close to the second fixing member 5, the second sliding groove 32 is formed at one end of the second movable member 3 close to the operating assembly 1, and the third sliding groove 21 is formed on the first movable member 2. The second sliding groove 32 and the third sliding groove 21 extend in the same direction, and are both designed as linear sliding grooves. The second sliding groove 32 extends along the length direction of the second movable member 3, and the third sliding groove 21 extends along the length direction of the first movable member 2. As Figure 1 shown, in the initial state, the extending directions of the second sliding groove 32 and the third sliding groove 21 have a certain angle with the Y direction and the Z direction. As the second movable member 3 and the first movable member 2 rotate clockwise, the extending directions of the second sliding groove 32 and the third sliding groove 21 gradually approach parallel to the Z direction, and finally the operating assembly 1 is in a horizontal state. The sliding part at the front end of the operating assembly 1 is slidably connected to the first movable member 2 through the third sliding groove 21, and the sliding part at the rear end of the operating assembly 1 is slidably connected to the second movable member 3 through the second sliding groove 32.

[0044] In some embodiments, when the operator rotates the first movable member 2 and the operating assembly 1 deflects to a specified position, the operator slides the operating assembly 1 along the sliding groove so that it translates relative to the second movable member 3 and the first movable member 2 to a specified position for locking and fixing. This specified position can be a certain position where the sliding part of the operating assembly 1 moves to the middle of the sliding groove, or the lower end position of the sliding groove. Therefore, by providing the second sliding groove 32 and the third sliding groove 21, the smoothness of the relative sliding between the operating assembly 1, the first movable member 2 and the second movable member 3 is ensured.

[0045] Optionally, referring to Figure 1 and Figure 2 , the base assembly 6 includes a fixing plate 61 and a sliding plate 62; both the first fixing member 4 and the second fixing member 5 are fixedly connected to the sliding plate 62, and the sliding plate 62 is slidably connected to the fixing plate 61.

[0046] Specifically, as Figure 1 and Figure 2As shown, the first fixing member 4 and the second fixing member 5 are fixed to the upper part of the sliding plate 62. A chute is formed between the flanging structures protruding from both sides of the fixing plate 61. The sliding plate 62 is slidably connected in the chute and slides relative to the fixing plate 61 along the Y direction. After the operating assembly 1 slides to a preset position along the positions of the second chute 32 and the third chute 21, the operator moves the sliding plate 62, so that the whole device including the operating assembly 1 slides horizontally along the Y-axis direction, generally realizing the sliding of the operating assembly 1 along the Y-axis and Z-axis directions, and the rotation around the X-axis, meeting the processing and manufacturing requirements of different product specifications and dimensions.

[0047] Optionally, referring to Figure 1 , it further includes a rotating shaft 7; the first movable member 2 is rotatably connected to the first fixing member 4 through the rotating shaft 7, and the arc curvature center of the first chute 31 is located on the rotating shaft 7.

[0048] Specifically, as shown in Figure 1 , the rotating shaft 7 is arranged at the top of the first fixing member 4, the first movable member 2 is rotatably connected to the rotating shaft 7, and the rotating shaft 7 is along the X direction. When the operator rotates the first movable member 2, the first movable member 2 rotates around the rotating shaft 7. In addition, the arc curvature center of the first chute 31 is located on the rotating shaft 7, so that during the movement process, the second movable member 3 can rotate along the path of the first chute 31 with the rotating shaft 7 as the axis, realizing the synchronous rotation of the first movable member 2 and the second movable member 3, and being beneficial to improving the rotation stability.

[0049] Optionally, referring to Figure 1 , it further includes a first locking member 81; the first locking member 81 is inserted into the first chute 31 and connected to the second fixing member 5, detachably connecting the second movable member 3 and the second fixing member 5.

[0050] Specifically, as shown in Figure 1 , the first locking member 81 is inserted into the first chute 31 and detachably connected to the second fixing member 5. The first locking member 81 includes but is not limited to bolts, screws or pins. Before the operation starts, the first locking member 81 is fixed in the first chute 31 to prevent the second movable member 3 from sliding relative to the second fixing member 5, and the whole device is limited and fixed. When the operation starts, the first locking member 81 is loosened, so that the second movable member 3 drives the second fixing member 5 to slide relative to each other along the first chute 31. When it moves to the preset position, the first locking member 81 is tightened to limit and fix the second movable member 3 to prevent it from displacing.

[0051] Optionally, referring to Figure 1It further includes a second locking member 82 and a third locking member 83; the second locking member 82 is disposed through the second chute 32 and connected to the operating assembly 1, detachably connecting the second movable member 3 and the operating assembly 1; the third locking member 83 is disposed through the third chute 21 and connected to the operating assembly 1, detachably connecting the first movable member 2 and the operating assembly 1.

[0052] Specifically, as Figure 1 shown, the second locking member 82 is disposed through the second chute 32 and detachably connected to the operating assembly 1. The third locking member 83 is disposed through the third chute 21 and detachably connected to the operating assembly 1. Before the operation starts, the second locking member 82 is fixed in the second chute 32, and the third locking member 83 is fixed in the third chute 21 to limit and fix the operating assembly 1 to prevent relative sliding between it and the first movable member 2 and the second movable member 3. When the operation starts, the second locking member 82 and the third locking member 83 are loosened, and the operating assembly 1 is moved to slide relative to the first movable member 2 and the second movable member 3 along the second chute 32 and the third chute 21. When it moves to a preset position, the second locking member 82 and the third locking member 83 are tightened to limit and fix the operating assembly 1 to prevent its displacement.

[0053] Optionally, referring to Figure 3 it further includes a fourth locking member 84; the fourth locking member 84 is detachably connected between the sliding plate 62 and the fixing plate 61.

[0054] Specifically, as Figure 3 shown, the fourth locking member 84 is detachably connected between the sliding plate 62 and the fixing plate 61. A locking groove 621 is formed on the sliding plate 62, and the fourth locking member 84 is disposed through the locking groove 621 to detachably connect the sliding plate 62 and the fixing plate 61. The number of the locking grooves 621 can be multiple, and each locking groove 621 is correspondingly provided with a fourth locking member 84. In this embodiment, a total of four locking grooves 621 are arranged in an array. Before the operation starts, the fourth locking member 84 is fixed between the sliding plate 62 and the fixing plate 61. When the operation starts, the fourth locking member 84 is loosened, and the sliding plate 62 is moved to translate relative to the fixing plate 61 along the Y direction. When the sliding plate 62 moves to a preset position, the fourth locking member 84 is tightened to limit and fix the sliding plate 62 to prevent its displacement relative to the fixing plate 61.

[0055] In some embodiments, the following steps are adopted to use the linkage device to adjust the position of the operating assembly 1:

[0056] Step 1: Loosen the first locking members 81 on the left and right sides. The operator rotates the first movable member 2, causing the first movable member 2 to rotate around the rotating shaft 7. The angle of the operating assembly 1 changes, and at the same time, drives the second movable member 3 to rotate around the rotating shaft 7. The second movable member 3 slides along the first sliding groove 31 relative to the second fixed member 5. Until the operating assembly 1 rotates to the preset position, tighten the first locking member 81.

[0057] Step 2: Loosen the second locking member 82 and the third locking member 83 on the left and right sides. Along the extending directions of the second sliding groove 32 and the third sliding groove 21, move the operating assembly 1, or rely on gravity to make the operating assembly 1 slide freely downward until it moves to the preset position, and tighten the second locking member 82 and the third locking member 83.

[0058] Step 3: Move the sliding plate 62 to translate it relative to the fixed plate 61 in the Y direction. When it moves to the preset position, tighten the fourth locking member 84. At this time, the operating assembly 1 has moved to the appropriate position for welding or dispensing of the corresponding battery.

[0059] Optionally, referring to Figure 1 , the operating assembly 1 includes a dispensing device 11 and a mounting plate 12; the dispensing device 11 is fixed on the mounting plate 12, and the mounting plate 12 is slidably connected to the second movable member 3 through the second sliding groove 32, and the mounting plate 12 is slidably connected to the first movable member 2 through the third sliding groove 21.

[0060] Specifically, as shown in Figure 1 , in this embodiment, taking the dispensing operation as an example, the operating assembly 1 includes a dispensing device 11 and a mounting plate 12. The dispensing device 11 is the dispensing head, and the mounting plate 12 is the fixing platform for the dispensing head to fix the dispensing head. The mounting plate 12 is slidably connected to the second movable member 3 through the second sliding groove 32. The second locking member 82 is disposed through the second sliding groove 32 for locking and fixing between the mounting plate 12 and the second movable member 3. The mounting plate 12 is slidably connected to the first movable member 2 through the third sliding groove 21. The third locking member 83 is disposed through the third sliding groove 21 for locking and fixing between the mounting plate 12 and the first movable member 2.

[0061] Optionally, referring to Figure 1 , the number of the second sliding grooves 32 and / or the third sliding grooves 21 is two, and the extending directions of different second sliding grooves 32 or third sliding grooves 21 are the same and are spaced apart.

[0062] Specifically, as shown in Figure 1As shown, there are two second sliding grooves 32 on each second movable member 3, and / or there are two third sliding grooves 21 on each first movable member 2. In this embodiment, two second sliding grooves 32 with the same extending direction are arranged at intervals on each second movable member 3, and two third sliding grooves 21 with the same extending direction are arranged at intervals on each first movable member 2. Correspondingly, a second locking member 82 is inserted into each second sliding groove 32, and a third locking member 83 is inserted into each third sliding groove 21. By increasing the number of sliding grooves, the sliding stability between the operating assembly 1, the first movable member 2 and the second movable member 3 is improved.

[0063] Optionally, referring to Figure 2 and Figure 3 , the number of both the first fixing member 4 and the second fixing member 5 is two; one first fixing member 4 and one second fixing member 5 are connected to one side of the base assembly 6, and the other first fixing member 4 and the other second fixing member 5 are connected to the other side of the base assembly 6. Each first fixing member 4 is connected to a first movable member 2, and each second fixing member 5 is connected to a second movable member 3.

[0064] Specifically, as shown in Figure 2 and Figure 3 , in this embodiment, a first fixing member 4, a second fixing member 5, a first movable member 2 and a second movable member 3 are respectively arranged on both sides of the sliding plate 62 along the X direction. Each first fixing member 4 is connected to a first movable member 2, and each second fixing member 5 is connected to a second movable member 3. A first movable member 2 and a second movable member 3 are connected to the left side of the operating assembly 1, and a first movable member 2 and a second movable member 3 are connected to the right side of the operating assembly 1. During the movement process, the first movable members 2 and the second movable members 3 on the left side and the right side rotate synchronously, and the relative sliding positions of the operating assembly 1 and the first movable members 2 and the second movable members 3 on the left side and the right side are the same, which is beneficial to improving the stability of the angle deflection and sliding process of the operating assembly 1. And the first fixing member 4, the second fixing member 5, the first movable member 2 and the second movable member 3 on each side are symmetrically distributed, ensuring the balance of the angle deflection and sliding process of the operating assembly 1.

[0065] Optionally, referring to Figure 1 , the sliding plate 62 is slidably connected to the fixing plate 61 along the first direction, and the axis of the rotating shaft 7 is perpendicular to the first direction.

[0066] Specifically, as shown in Figure 1As shown, the sliding plate 62 slides relative to the fixed plate 61 in the first direction Y, and the axis of the rotating shaft 7 is in the second direction X. The initial extending directions of the second sliding groove 32 and the third sliding groove 21 have a certain angle with the third direction Z and the first direction Y. As the first moving member 2 and the second moving member 3 rotate clockwise, the angles between the extending directions of the second sliding groove 32 and the third sliding groove 21 and the third direction Z gradually decrease and finally become parallel to the third direction Z. Therefore, the overall device is realized to slide in the first direction Y, the operating assembly 1 slides in the third direction Z and the first direction Y, and the operating assembly 1 rotates around the second direction X, realizing the functions of adjusting the horizontal position, height position and angle of the dispensing device or the welding device, and adapting to the battery assembly requirements of different specifications and sizes.
