[0019] Beneficial effects of the present invention:

[0020] 1. The present invention relates to an automatic battery assembly device suitable for battery production. By setting a right prism and a detection unit, a first pressure block on the right prism contacts the top of the battery pack, and a pressure plate on the side of the first pressure block away from the right prism contacts the battery cell of the battery pack and squeezes the pressure sensor. When multiple pressure plates contact the corresponding battery cells respectively, multiple pressure sensors will measure pressure parameters at the same time. When a battery cell is misaligned, the pressure parameter of the corresponding pressure sensor will be abnormal. The greater the misalignment, the greater the difference in pressure parameters. When the abnormal parameter exceeds the predetermined range, it means that the battery cell is misaligned to a large extent, so that it can be judged that the surface of the battery pack is not smooth enough, and the staff can be reminded to make adjustments.

[0021] 2. The present invention relates to an automated battery assembly device suitable for battery production. By installing a first pressing block at different positions of multiple faces of a right prism, when a single or specific position of a battery cell needs to be tested, the first motor drives the installation shaft and the right prism to rotate a certain angle so that different faces face the battery pack. The battery cells at different positions can be tested. The first pressing block at a specific position applies a certain pressure to the specific battery cell, so the compressive strength of the specific battery cell can be tested. After the first pressing block at the specific position applies a predetermined pressure, all the battery cells are tested. If the battery cell at the specific position is not misaligned or deformed, the battery pack is qualified.

[0022] 3. The present invention relates to an automated battery assembly device suitable for battery production. By setting a limit groove, a limit block, a mounting strip and a mounting groove, the first pressure block is installed on the straight prism through the limit groove and the limit block, and the first pressure block can be quickly disassembled and assembled through the mounting groove and the mounting strip. When the first pressure block is damaged, the first pressure block can be directly slid along the mounting groove, and the two limit blocks are close to each other and squeeze the spring, so that the first pressure block can be removed and replaced with higher efficiency. When disassembling the first pressure blocks in batches, the staff uses a baffle to support one side of the first pressure block, and the first motor drives the straight prism to rotate a certain angle, and the first pressure block and the mounting strip will slide along the mounting groove, thereby quickly removing all the first pressure blocks.

[0023] 4. The present invention relates to an automatic battery assembly device suitable for battery production. By setting a slide plate, a slide column, an arc portion, a strip portion and a slot, the side pressure plate moves downward. When the slide column is located in the strip portion, the bottom of the second pressure block contacts the battery cell. At this time, the slide column located in the arc portion is not stuck and will not be subject to resistance from the battery cell. The slide column located in the strip portion is locked, thereby applying pressure to a specific battery cell to detect its strength; all the slide columns are located in the strip portion or the arc portion at the same time, and each slide column is locked or not locked when contacting the battery cell, thereby detecting the flatness of the battery pack; the slide plate is driven to move by an electric push rod, so that the slide column can be selectively located in the arc portion or the strip portion, thereby completing the application of pressure to the battery cell at a specific position and reducing the number of detection units.

[0024] 5. The battery automation assembly equipment suitable for battery production described in the present invention is provided with a rotating plate, a second motor, a first vertical shaft, a rotating ring and an electric spray pot. The horizontal plate drives the rotating plate to move downward through the mounting plate and the mounting shaft. The third pressure block at the bottom of the rotating plate can contact the battery pack on the workbench and detect the battery cells of the battery pack. When pressure is applied to the battery cells at a specific position, the output end of the second motor drives the rotating plate to rotate a certain angle through the first vertical shaft, so that the third pressure block at the corresponding position is located above the battery pack. The rotating plate moves downward to apply pressure to the specific battery cells. When unqualified products are detected, the electric spray pot sprays ink on the battery pack to mark the unqualified products. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figure 1-Figure 5As shown, the detection mechanism is a straight prism 2, and the mounting plate 16 is detachably connected to the transverse plate 12 by bolts. The mounting plate 16 is connected to the mounting shaft 17. When installing the straight prism 2, the two mounting plates 16 are removed, and the mounting shafts 17 at both ends of the straight prism 2 are installed on the mounting plates 16, and then the mounting plates 16 are connected to the transverse plate 12, and finally the output end of the first motor 15 is connected to one of the mounting shafts 17 through a coupling; after the battery cell group is assembled into a battery pack, the battery pack is placed at a predetermined position on the workbench 1 by a manipulator, and the battery pack is moved to the bottom of the straight prism 2 via a conveyor belt, and the external press above the hydraulic rod 13 drives the hydraulic rod 13 to push the transverse plate 12 downward, and the transverse plate 12 is connected to the mounting plate 16 and the mounting shaft 17 drive the right prism 2 to move downward. After the right prism 2 moves downward for a certain distance, the first pressing block 300 on the right prism 2 contacts the top of the battery pack. The pressing plate 31 on the side of the first pressing block 300 away from the right prism 2 contacts the battery cell of the battery pack and squeezes the pressure sensor 34. When multiple pressing plates 31 contact the corresponding battery cells respectively, multiple pressure sensors 34 will measure pressure parameters at the same time. When a battery cell is misaligned, the pressure parameter of the corresponding pressure sensor 34 will be abnormal. The greater the misalignment, the greater the difference in pressure parameters. When the abnormal parameter exceeds the predetermined range, it means that the battery cell is misaligned, so it can be judged that the surface of the battery pack is not smooth enough, reminding the staff to make adjustments.

[0045] The first pressing block 300 corresponds to the position of the battery cell. When a single or specific position of the battery cell needs to be tested, the first pressing block 300 is installed at different positions of multiple faces of the right prism 2. The first motor 15 drives the installation shaft 17 and the right prism 2 to rotate a certain angle so that different faces face the battery pack. The battery cells at different positions can be tested. The first pressing block 300 at a specific position applies a certain pressure to the specific battery cell, so that the compressive strength of the specific battery cell can be tested. After the first pressing block 300 at a specific position applies a predetermined pressure, all the battery cells are tested. If the battery cell at the specific position is not misaligned or deformed, the battery pack is qualified.

[0046] The first pressing block 300 is installed on the straight prism 2. A plurality of mounting grooves 21 are provided on each side of the straight prism 2. A mounting strip 23 is slidably installed in the mounting groove 21. The side of the mounting strip 23 away from the straight prism 2 is fixedly connected to the first pressing block 300. The mounting strip 23 is provided with a rectangular groove along its width direction. Two limit blocks 24 are relatively slidably installed in the rectangular groove. A center plate 27 is fixedly installed in the middle of the rectangular groove. A center hole 26 is provided on the center plate 27. A spring is fixed in the center hole 26. Both ends of the spring are respectively fixed to the two limit blocks 24. The inner walls on both sides of the mounting groove 21 are provided with limit grooves 22, the limit blocks 24 can be stuck in the limit grooves 22, and the limit blocks 24 are chamfered; the first pressure block 300 is installed on the straight prism 2 through the limit grooves 22 and the limit blocks 24, and the first pressure block 300 can be quickly disassembled and assembled through the mounting groove 21 and the mounting strip 23. When the first pressure block 300 is damaged, the first pressure block 300 can be directly slid along the mounting groove 21, and the two limit blocks 24 are close to each other and squeeze the spring, so that the first pressure block 300 can be removed and replaced, which is more efficient.

[0047] Since the right prism 2 can rotate, when disassembling the first pressing blocks 300 in batches, the staff only needs to use a baffle to support one side of the first pressing blocks 300. The right prism 2 rotates a certain angle, and the first pressing blocks 300 and the mounting strip 23 slide along the mounting groove 21, thereby quickly removing all the first pressing blocks 300.

[0048] Example 2

[0049] The difference between Example 2 and Example 1 is that the detection mechanism is a side pressure plate 4;

[0050] like Figure 5-Figure 11 As shown,

[0051] The detection mechanism is a side pressure plate 4, which is connected to the mounting shaft 17. The side pressure plate 4 is horizontally provided with a flat groove 41, which is located in the middle and lower part of the side pressure plate 4. A slide plate 40 is slidably installed in the flat groove 41 along the width direction of the side pressure plate 4. The slide plate 40 is provided with a plurality of long grooves 46 along its sliding direction. A plurality of vertical grooves are provided at the bottom of the side pressure plate 4. A slide column 42 is installed in the vertical groove. A second spring rod 43 is provided at the top of the slide column 42. The top of the second spring rod 43 is fixedly connected to the inner wall of the top of the vertical groove, and the bottom is connected to the top of the slide column 42. A second pressure block 400 is connected to the bottom of the slide column 42. A card slot 49 is provided on the side of the slide column 42. When the two spring rods 43 are in a natural state, the slot 49 and the flat slot 41 are located on the same horizontal line, the sliding column 42 is located in the long slot 46, and the sliding column 42 corresponds to the long slot 46 one by one; a fixing plate 47 is vertically fixed at one end of the sliding plate 40, and an electric push rod 48 is provided on one side of the fixing plate 47, one end of the electric push rod 48 is fixedly connected to the fixing plate 47, and the other end is fixedly connected to the side pressure plate 4; an arc portion 44 and a strip portion 45 are provided on the side wall of the long slot 46, the diameter of the arc portion 44 is larger than the diameter of the sliding column 42, the width of the strip portion 45 is smaller than the diameter of the sliding column 42, and the strip portion 45 can cooperate with the slot 49 on the sliding column 42.

[0052] The horizontal plate 12 drives the side pressure plate 4 to move downward through the mounting plate 16 and the mounting shaft 17 on the side pressure plate 4, and the sliding column 42 and the second pressure block 400 move with it until the bottom of the second pressure block 400 contacts the battery cell corresponding to the battery pack. The arc portion 44 and the strip portion 45 on the slide plate 40 are arranged according to a certain rule. When the sliding column 42 is located in the strip portion 45, the bottom of the second pressure block 400 contacts the battery cell, and the second pressure block 400 has a tendency to compress the second spring rod 43, the strip portion 45 clamps the card slot 49 to prevent the sliding column 42 from moving up. At this time, the sliding column 42 located in the arc portion 44 is not When the side pressure plate 4 moves downward, the slide column 42 in the strip portion 45 is locked, thereby applying pressure to a specific battery cell to detect its strength. All the slide columns 42 are simultaneously located in the strip portion 45 or the arc portion 44. Each slide column 42 is locked or not locked when in contact with the battery cell, thereby detecting the flatness of the battery pack. The slide plate 40 is driven to move by the electric push rod 48, so that the slide column 42 can be selectively located in the arc portion 44 or the strip portion 45, thereby completing the application of pressure to the battery cell at a specific position and reducing the number of detection units.

[0053] Example 3

[0054] The difference between Example 3 and Example 1 is that the detection mechanism is a rotating plate 6;

[0055] like Figure 5 , Figure 14-15 As shown,

[0056] A top plate 50 is rotatably connected to the top of the rotating plate 5, and the top plate 50 is connected to the mounting shaft 17. A plurality of first connecting columns 52 are fixedly connected to the top of the rotating plate 5. A swivel 54 is rotatably mounted on the bottom of the top plate 50, and the tops of the plurality of first connecting columns 52 are fixedly connected to the swivel 54. A second motor 51 is provided on the top of the top plate 50, and the output end of the bottom of the second motor 51 is fixedly connected to the top of the rotating plate 5 through a first vertical shaft 55. A plurality of groups of third pressing blocks 500 are provided along the circumferential direction at the bottom of the rotating plate 5, and an electric spray pot 53 is provided on the side of the rotating plate 5. A nozzle facing the battery pack is provided at the bottom of the electric spray pot 53.

[0057] The horizontal plate 12 drives the rotating plate 5 to move downward through the mounting plate 16 and the mounting shaft 17 on the rotating plate 5. At this time, the rotating plate 5 is located above the workbench 1. The third pressure block 500 at the bottom of the rotating plate 5 can contact the battery pack on the workbench 1 and detect the battery cells of the battery pack. When pressure is applied to the battery cells at a specific position, the output end of the second motor 51 drives the rotating plate 5 to rotate a certain angle through the first vertical shaft 55, so that the third pressure block 500 at the corresponding position is located above the battery pack. The rotating plate 5 moves downward to apply pressure to the specific battery cell, and then the second motor 51 drives the rotating plate 5 to rotate to the initial position, and multiple third pressure blocks 500 are used to detect the battery pack. When unqualified products are detected, the electric spray pot 53 sprays ink on the battery pack to mark the unqualified products. The ink in the electric spray pot 53 is easy-to-clean ink, and the ink can be directly wiped off after processing.

[0058] Example 4

[0059] The difference between Example 4 and Example 3 is that a bottom plate 6 and a base 6 are added to one side of the workbench 1, and the position of the workbench 1 is changed;

[0060] like Figure 5 , Figure 12-Figure 15 As shown,

[0061] After adding the bottom plate 6 and the base 60, the bottom plate 6 and the base 60 are located on one side of the workbench 1, and the bottom plate 6 is located directly above the rotating plate 5. At this time, a group of clamping manipulators (not shown in the figure) are respectively arranged on both sides of the bottom plate 6, one group is used to clamp the battery pack on the workbench 1 and send it to the bottom plate 6, and the other group is used to send the battery pack on the bottom plate 6 that has been inspected back to the workbench 1;

[0062] A circular plate 64 is rotatably mounted at the bottom of the bottom plate 6. A second connecting column 63 is fixedly connected to the bottom of the circular plate 64. The bottom of the second connecting column 63 is fixedly connected to the base 60. A third motor 61 is fixedly mounted on the inner wall of the bottom of the base 60. A second vertical shaft 62 is fixedly connected to the top of the output end of the third motor 61. The top of the second vertical shaft 62 passes through the circular plate 64 and is fixedly connected to the bottom plate 6. A hole for the second vertical shaft 62 to pass through is provided on the circular plate 64. The horizontal plate 12 drives the rotating plate 5 to move downward through the mounting plate 16 and the mounting shaft 17 on the rotating plate. When the rotating plate 5 detects a group of battery packs on the bottom plate 6, the third motor 61 drives the bottom plate 6 to rotate through the second vertical shaft 62, so that the battery packs correspond to the third pressing blocks 500 at different positions. At this time, the second motor 51 does not work, the rotating plate 5 does not rotate, and the bottom plate 6 is flatter than the conveyor belt on the workbench 1. The battery packs are detected on the bottom plate 6, and the detection is more accurate.

[0063] When the pressure plate 31 is squeezed, the first spring rod 35 is compressed, and the limiting rod 32 squeezes the pressure sensor 34, thereby measuring the pressure exerted on the pressure plate 31. One end of the first spring rod 35 is fixedly connected to the pressure plate 31, and the other end is fixedly connected to the first pressure block 300; the limiting rod 32 and the limiting hole 33 limit the pressure plate 31. The structures of the second pressure block 400 and the third pressure block 500 are the same as those of the first pressure block 300. The second pressure block 400 and the third pressure block 500 are also provided with the first spring rod 35, the limiting hole 33, the limiting rod 32 and the pressure sensor 34.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
