Description

Technical Field

[0001] This invention relates to an improved NG buffer mechanism for new energy lithium batteries. Background Technology

[0002] After visual inspection, lithium batteries marked as NG (Not Good) are picked up by a robotic arm and placed into a buffer mechanism for buffering. On some testing equipment with sufficient installation space, a new energy lithium battery NG buffer mechanism, such as the one announced on June 27, 2023 (authorization announcement number CN219258769U), can be used. This new energy lithium battery NG buffer mechanism includes at least three buffer conveyor lines: a middle buffer conveyor line, a lower buffer conveyor line, and at least one upper buffer conveyor line. A cell lifting platform transports the NG lithium batteries to the aforementioned at least three buffer conveyor lines. However, for testing equipment with limited installation space, the currently disclosed new energy lithium battery NG buffer mechanism is not applicable. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an improved NG buffer mechanism for new energy lithium batteries that occupies less space and is easy to embed into existing testing equipment.

[0004] To achieve the above objectives, the technical solution adopted by this invention is: an improved NG buffer mechanism for new energy lithium batteries, comprising:

[0005] The conveyor line is horizontally positioned.

[0006] The magazine is arranged longitudinally, and the conveyor line runs through the magazine. The magazine has multiple storage cavities arranged from top to bottom, and the magazine has a clearance cavity for the conveyor line to pass through.

[0007] The lifting module drives the magazine cartridge to rise and fall within the height range of the clearance cavity. Each time the lifting module drives the magazine cartridge to rise and fall by the height of one storage cavity, the lifting module will drive the magazine cartridge to rise and fall by the height of one storage cavity.

[0008] The lifting assembly is installed on the conveyor line. The lifting assembly includes a lifting plate and a lifting cylinder. The lifting plate is driven by the lifting cylinder and can switch back and forth between two states: above the conveyor line and connected to the conveyor line. There is a magazine waiting position between the lifting plate and the magazine hopper. The conveyor line is driven by a servo motor to move a fixed distance. The distance from the magazine waiting position to the storage cavity is a fixed distance.

[0009] The beneficial effects of the improved NG buffer mechanism for new energy lithium batteries of this invention are that a clearance cavity is set in the magazine compartment, allowing the conveyor line to pass through the magazine compartment without affecting the lifting module's ability to lift the magazine compartment. Through ingenious design, the conveyor line and magazine compartment are arranged in a "+" shape, and the lifting component on the conveyor line receives the NG battery cells transferred by the robotic arm. This reduces the floor space, makes the structure compact, and is easy to embed into existing testing equipment. The conveyor line directly feeds the battery cells into the magazine compartment for storage, and the lifting module moves the magazine compartment up and down by a fixed length, meeting the needs of buffering and producing a large number of battery cells.

[0010] Preferably, the magazine compartment includes a frame and m pairs of support plates arranged within the frame, where m > 1 and is a natural number. The m pairs of support plates are arranged longitudinally, and each pair of support plates includes two support plates parallel to the horizontal plane. There is a gap between each pair of two support plates, and the m gaps correspond to each other to form a clearance cavity. The space above each pair of two support plates forms a storage cavity.

[0011] Preferably, the conveyor line includes a frame, a synchronous belt, a drive pulley, and two synchronous pulleys. The drive pulley is rotatably positioned in the middle of the frame, and the two synchronous pulleys are rotatably positioned at both ends of the frame. The synchronous belt is fitted onto the drive pulley and the two synchronous pulleys and meshes with each other through a toothed structure. The frame and the synchronous belt pass through a relief cavity. A servo motor is fixed to the frame, and its output shaft is connected to the drive pulley. The conveyor line uses the drive pulley, synchronous pulleys, and synchronous belt for transport, and is driven by the servo motor to move the battery cell products a fixed distance, ensuring the transmission accuracy of the conveyor line.

[0012] Preferably, the frame is equipped with multiple adjustable tension pulleys, and the synchronous belt is wound around these pulleys. The arrangement of the tension pulleys allows for adjustment of the tension of the synchronous belt to suit battery cell products of different qualities.

[0013] Preferably, the tensioning pulleys are symmetrically arranged on both sides of the drive pulley. This ensures the tension of the synchronous belts on both sides of the drive pulley, resulting in high transmission accuracy and stable transmission of the conveyor belt.

[0014] Preferably, the side wall of the frame is provided with multiple sets of matching first sliders and adjusting blocks, the same number as the tensioning wheels. Each set of first sliders is slidably disposed on the side wall of the frame, and each tensioning wheel is rotatably disposed on its corresponding first slider. Each set of adjusting blocks is fixed on the side wall of the frame, and adjusting bolts are provided on the adjusting blocks. The adjusting bolts are threadedly engaged with the first sliders. When the adjusting bolts are rotated, the first sliders drive the tensioning wheels to slide back and forth along the transmission direction of the synchronous belt.

[0015] Preferably, a first through-beam photoelectric sensor is installed on the lifting plate to sense whether there are battery cells on the lifting plate; a third through-beam photoelectric sensor is installed on the frame, located between the magazine waiting position and the lifting plate, to sense whether there are battery cells in the interval between the magazine waiting position and the lifting plate; two pairs of fourth through-beam photoelectric sensors are installed on the frame, with their beams directed on both sides of the magazine hopper, to sense whether battery cells are entering or leaving the magazine hopper; two pairs of fifth through-beam photoelectric sensors are installed on the frame, with their beams directed through the storage cavity of the upper layer that connects to the conveyor line, to sense whether there are battery cells entering or leaving the magazine hopper. The storage chamber is connected to the upper layer. A photoelectric sensor is installed on the frame, which is aligned with the storage chamber connected to the conveyor line to sense whether there are battery cells in the storage chamber. The conveyor line has a magazine discharge position, which is symmetrically located on both sides of the magazine waiting position. A photoelectric sensor is installed on the frame of the magazine discharge position to sense whether there are battery cells in the magazine discharge position. A manual picking position is located on one side of the magazine discharge position, between the manual picking position and the magazine chamber. A photoelectric sensor is installed at the manual picking position to sense whether there are battery cells in the manual picking position.

[0016] Preferably, there are two sets of lifting plates, which are driven to rise and fall by the same lifting cylinder. The distance between the two lifting plates is a fixed distance. Each set of lifting plates is equipped with a photoelectric sensor one, and two pairs of photoelectric sensors two are installed on the frame of the conveyor line between the two sets of lifting plates to sense whether there are battery cell products on the conveyor line between the two sets of lifting plates.

[0017] Preferably, each set of lifting plates includes two vertically arranged lifting plates located on both sides of the conveyor line. The bottoms of the four lifting plates are fixed to the same base plate. The two lifting plates are vertically arranged to ensure that the operation of the conveyor line is not affected when the lifting plates are working. At the same time, the bottom is fixed by the same base plate, which is driven to rise and fall by a lifting cylinder to ensure the synchronization of the four lifting plates.

[0018] Preferably, the lifting module includes a lifting motor, a lead screw, a second slider, and a fixed frame. The second slider is slidably mounted on the fixed frame and can slide up and down on the fixed frame. The lifting motor is fixed on the fixed frame, and its output end is connected and fixed to the lead screw. The lead screw and the second slider are threaded together, and the frame is fixed on the second slider. The lifting module uses lead screw transmission to drive the magazine feeder to rise and fall, which has high precision and stable transmission, meeting the needs of actual production.

[0038] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0039] See appendix Figure 1 , 2 As shown, this embodiment discloses an improved new energy lithium battery NG buffer mechanism, including: a conveyor line 10, a lifting component 40, a magazine 20, and a lifting module 30. The conveyor line 10 is used to horizontally convey NG battery cell products 70. The lifting component 40 is used to connect the NG battery cell products 70 on the robotic arm and convey them to the conveyor line 10. The magazine 20 is used to buffer the NG battery cell products 70. The lifting module 30 is used to drive the magazine 20 to lift and lower.

[0040] See appendix Figure 5 , 6 As shown, the conveyor line 10 in this embodiment includes a frame 12, a synchronous belt 13, a drive pulley 14, and two synchronous pulleys 15. The drive pulley 14 is rotatably disposed in the middle of the frame 12, and the two synchronous pulleys 15 are rotatably disposed at both ends of the frame 12. The synchronous belt 13 is sleeved on the drive pulley 14 and the two synchronous pulleys 15 and meshes with each other through a toothed structure. The servo motor 11 is fixed on the frame 12, and its output shaft is connected to the drive pulley 14 to drive the synchronous belt 13 to transmit power on the two synchronous pulleys 15.

[0041] A lifting assembly 40 is mounted on the conveyor line 10. The lifting assembly 40 includes a lifting plate 41 and a lifting cylinder 42. The lifting plate 41 is driven by the lifting cylinder 42 and can switch between two states: above the conveyor line 10 and connected to the conveyor line 10. There is a magazine waiting position S1 between the lifting plate 41 and the magazine hopper 20. The conveyor line 10 is driven by a servo motor 11 to move a fixed distance. The distance from the magazine waiting position S1 to the storage cavity 21 is a fixed distance. A through-beam photoelectric sensor 53 is mounted on the frame 12. The through-beam photoelectric sensor 53 is a Panasonic CX-411-P model. The through-beam photoelectric sensor 53 is located between the magazine waiting position S1 and the lifting plate 41 to sense whether there is a battery cell product 70 in the interval between the magazine waiting position S1 and the lifting plate 41.

[0042] like Figure 10As shown, there are two sets of lifting plates 41. Each set of lifting plates 41 includes two vertically arranged lifting plates 41, located on both sides of the conveyor line 10. The bottoms of the four lifting plates 41 are fixed on the same base plate 43. The base plate 43 is driven to rise and fall by a lifting cylinder 42, thereby realizing the synchronous rise and fall of the four lifting plates 41 by one lifting cylinder 42. Both sets of lifting plates 41 are equipped with through-beam photoelectric sensors 51 to sense whether there is a battery cell product 70 on the lifting plate 41. In this embodiment, the through-beam photoelectric sensor 51 is a Panasonic CX-411-P model.

[0043] like Figure 5 , 8 As shown in Figure 9, the distance between the two sets of lifting plates 41 is a fixed length. Two pairs of through-beam photoelectric sensors 52 are installed on the frame 12 of the conveyor line 10 located between the two sets of lifting plates to sense whether there is a battery cell product 70 on the conveyor line 10 between the two sets of lifting plates. The through-beam photoelectric sensors 52 are Panasonic CX-411-P models.

[0044] like Figure 1 , 2 As shown, the magazine hopper 20 is arranged longitudinally, and the conveyor line 10 passes through the magazine hopper 20. The magazine hopper 20 has multiple storage cavities 21 arranged sequentially from top to bottom. The magazine hopper 20 is provided with a clearance cavity 22 for the conveyor line 10 to pass through. In this embodiment, the frame 12 and the timing belt 13 both pass through the clearance cavity 22. By setting the clearance cavity 22, it is ensured that even if the conveyor line 10 passes through the magazine hopper 20, the lifting and lowering of the magazine hopper 20 will not be affected, provided that the height position of the conveyor line 10 remains unchanged. The design is ingenious.

[0045] like Figure 3 , 4 As shown, the magazine hopper 20 includes a frame 23 and m pairs of support plates 24 disposed within the frame 23, where m > 1 and is a natural number. In this embodiment, nineteen pairs of support plates 24 are provided. The nineteen pairs of support plates 24 are arranged longitudinally from top to bottom. Each pair of support plates 24 includes two support plates 24 parallel to the horizontal plane. There is a gap between each pair of two support plates 24. The m gaps correspond sequentially from top to bottom to form a clearance cavity 22. The space above each pair of two support plates 24 forms a storage cavity 21. This space refers to the space above the lower pair of support plates 24 and below the adjacent upper pair of support plates 24, as well as the unobstructed space of the uppermost pair of support plates 24. Both of these types of spaces form the storage cavity 21.

[0046] Two pairs of photoelectric sensors 454 are installed on the frame 12. The photoelectric sensors 454 are Panasonic CX-411-P models. The two pairs of photoelectric sensors 454 are located on both sides of the magazine 20 to sense whether the battery cell product 70 enters or exits the magazine 20.

[0047] Two pairs of photoelectric sensors 55 are installed on the rack 12. The photoelectric sensors 55 are Panasonic CX-411-P models. The photoelectric direction of the two pairs of photoelectric sensors 55 passes through the storage cavity 21 of the upper layer that is connected to the conveyor line 10. They are used to sense the position of the storage cavity 21 of the upper layer that is connected to the conveyor line 10 and to determine whether there is a battery cell product 70 in the storage cavity 21 of the upper layer.

[0048] A photoelectric sensor 61 is installed on the frame 12. The photoelectric sensor 61 is a Panasonic CX-421-P model. The photoelectric sensor 61 is aligned with the storage cavity 21 that is connected to the conveyor line 10 to sense whether there is a battery cell product 70 in the storage cavity 21 connected to the conveyor line 10.

[0049] The conveyor line 10 has a magazine discharge position S2, which is symmetrically located on both sides of the magazine storage compartment 20 with the magazine waiting position S1. A through-beam photoelectric sensor 56 is installed on the frame 12 of the magazine discharge position S2. The through-beam photoelectric sensor 56 is a Panasonic CX-411-P model, which is used to sense whether there is a battery cell product 70 at the magazine discharge position S2.

[0050] The magazine discharge position S2 is located on one side of the manual material handling position S3. The magazine discharge position S2 is located between the manual material handling position S3 and the magazine 20. A photoelectric sensor 62 is installed at the manual material handling position S3. The photoelectric sensor 62 is a Panasonic CX-421-P model and is used to sense whether there is a battery cell product 70 at the manual material handling position S3.

[0051] like Figure 1 , 2 As shown in Figure 3, the lifting module 30 includes a lifting motor 31, a lead screw, a second slider 32, and a fixed frame 33. The second slider 32 is slidably mounted on the fixed frame 33 and can slide up and down on the fixed frame 33. The lifting motor 31 is fixed on the fixed frame 33, and its output end is connected and fixed to the lead screw. The lead screw and the second slider 32 are threaded together. The frame 23 is fixed on the second slider 32. When the lifting motor 31 rotates, it drives the lead screw to rotate, which in turn forces the second slider 32 to slide up and down on the fixed frame 33, thereby driving the magazine hopper 20 to lift and lower.

[0052] In this embodiment, the lifting and lowering of the magazine 20 is limited by the height of the relief cavity 22. The lifting module 30 can only drive the magazine 20 to rise and fall within the height range of the relief cavity 22, and the lifting module 30 drives the magazine 20 to rise and fall by the height of one storage cavity 21 each time.

[0053] In some embodiments, such as Figure 6 , 7 As shown, multiple adjustable tensioning pulleys 16 can be added to the frame 12, and the synchronous belt 13 is wound around the multiple tensioning pulleys 16. The tensioning pulleys 16 are symmetrically arranged on both sides of the drive pulley 14. The side wall of the frame 12 is provided with multiple sets of matching first sliders 17 and adjusting blocks 18, the same number as the tensioning pulleys 16. Each set of first sliders 17 is slidably disposed on the side wall of the frame 12, and each tensioning pulley 16 is rotatably disposed on its corresponding first slider 17. Each set of adjusting blocks 18 is fixed on the side wall of the frame 12, and adjusting bolts 19 are provided on the adjusting blocks 18. The adjusting bolts 19 are threadedly engaged with the first sliders 17. When the adjusting bolts 19 are rotated, the first sliders 17 drive the tensioning pulleys 16 to slide back and forth along the transmission direction of the synchronous belt 13, thereby adjusting the tension of the synchronous belt 13.

[0054] The working principle of photoelectric sensor 61 is as follows: when photoelectric sensor 61 senses the state of product 70 without battery cell, the conveyor line 10 can operate to convey product 70 with battery cell; when clearing the cartridge hopper 20, the lifting module 30 descends to release the material; when photoelectric sensor 61 senses the state of product 70 with battery cell, the conveyor line 10 cannot operate; when collecting the cartridge hopper 20, the lifting module 30 rises to bring the product 70 with battery cell to the upper layer.

[0055] When collecting battery cell products 70 in magazine 20: When both photoelectric sensor 61 and through-beam photoelectric sensor 55 detect the presence of battery cell products 70, the lifting module 30 moves upward a fixed distance to move the battery cell products 70 to the next layer, and the action is repeated.

[0056] When clearing the battery cell product 70 from the magazine hopper 20: When both photoelectric sensor 61 and through-beam photoelectric sensor 55 detect the presence of battery cell product 70, the production line drive will discharge the battery cell product 70 material from that layer. That is, when photoelectric sensor 61 detects no material and through-beam photoelectric sensor 55 detects material, the lifting module 30 will move downwards at a fixed distance to move the upper layer of battery cell product 70 to the conveyor line 10, and the action will be repeated.

[0057] The working principle of this embodiment is as follows: the robotic arm picks up two battery cell products 70 and places them on two sets of lifting plates 41. Two pairs of photoelectric sensors 52 detect the material, and the lifting cylinder 42 descends, bringing the battery cell products 70 to the synchronous belt 13 of the conveyor line 10. The servo motor 11 drives the synchronous belt 13 to travel a fixed distance, which in turn drives the battery cell products 70 on the conveyor line 10 to move a fixed distance. The battery cell products 70 on the lifting plate 41 near the magazine hopper 20 are first moved to the magazine waiting position S1.

[0058] When the magazine hopper 20 is completely empty, the lifting module 30 aligns the uppermost storage cavity 21 of the magazine hopper 20 with the synchronous belt 13, that is, the uppermost pair of support plates 24 align with the two sides of the synchronous belt 13. When photoelectric sensor 1 61, photoelectric sensor 2 62 and through-beam photoelectric sensor 4 54 detect no material, the servo motor 11 drives the battery cell product 70 on the magazine waiting position S1 to move a fixed distance to the uppermost storage cavity 21. When photoelectric sensor 1 61 detects material and through-beam photoelectric sensor 4 54 detects no material, the lifting module 30 rises a fixed distance by the height of one storage cavity 21, bringing the battery cell product 70 to the uppermost magazine hopper 20 position on the conveyor line 10, and aligning the empty storage cavity 21 with the conveyor line 10.

[0059] When photoelectric sensor 1 61, photoelectric sensor 2 62 and through-beam photoelectric sensor 4 54 detect no material and through-beam photoelectric sensor 55 detects material, servo motor 11 drives the battery cell product 70 on the magazine waiting position S1 on the conveyor line 10 to move a fixed distance to the empty storage cavity 21, and repeats the action.

[0060] When there is no material at the receiving position of the lifting assembly 40 (when the two sets of lifting plates 41 are in the lowered state), that is, when the photoelectric sensor 1 51, photoelectric sensor 2 52, and photoelectric sensor 3 53 sense the absence of the battery cell product 70, the lifting cylinder 42 moves upward to prepare to receive the battery cell product 70 from the robotic arm, and the action is repeated.

[0061] The material handling principle of the battery cell product 70 in the manual re-inspection and cleaning chamber 20 of this embodiment is as follows:

[0062] When the magazine hopper 20 is full, manual emptying is required. When the lifting module 30 rises to its limit position, i.e., photoelectric sensor 1 61 detects no material and photoelectric sensor 55 detects material, the lifting module 30 places the battery cell product 70 in the lowest storage cavity 21 of the magazine hopper 20 onto the synchronous belt 13. When photoelectric sensors 4 54 and 6 56 detect no material, and photoelectric sensor 1 61 and photoelectric sensor 2 62 detect no material, the servo motor 11 drives the battery cell product 70 placed on the synchronous belt 13 to move a fixed distance to the magazine hopper discharge position S2 on one side of the magazine hopper 20.

[0063] When photoelectric sensor 1 (61) detects no material and through-beam photoelectric sensor 5 (55) detects material, the lifting module 30 drives the magazine hopper 20 to descend, placing the battery cell product 70 in the upper storage cavity 21 of the magazine hopper 20 onto the synchronous belt 13. When through-beam photoelectric sensor 4 (54) detects material, through-beam photoelectric sensor 6 (56) detects no material, and photoelectric sensor 1 (61) and photoelectric sensor 2 (62) detect no material, the servo motor 11 moves the battery cell product 70 placed on the synchronous belt 13 a fixed distance to the magazine hopper discharge position S2 of the magazine hopper 20. The battery cell product 70 originally at the magazine hopper discharge position S2 is synchronously moved to the manual material picking position S3 on one side. When photoelectric sensor 2 (62) detects material, the manual person needs to take out the material, and the action is repeated.

[0064] It should be noted that both the conveyor line 10 and the lifting module 30 are fixed-length distance transmissions.

[0065] The following advantages are available after adopting this technical solution:

[0066] 1. High transmission accuracy and stable transmission: The conveyor line 10 uses synchronous pulleys 15 and synchronous belts 13 for conveying, and is driven by servo motor 11 to move the battery cell product 70 a fixed distance, ensuring the transmission accuracy of the conveyor line 10; the lifting module 30 uses a screw drive to drive the spring clip hopper 20 to rise and fall, which has high accuracy and stable transmission, meeting the needs of actual production.

[0067] 2. Small equipment size and large buffer quantity: The conveyor line 10 directly feeds the battery cell products 70 into the magazine hopper 20 for storage, and the lifting module 30 drives the magazine hopper 20 to move up and down a fixed length, which meets the needs of buffering and production of a large number of battery cell products 70.

[0068] Third, cost reduction: The buffer for a large number of battery cell products 70 is carried out by conveyor line 10, which directly feeds the battery cell products 70 into the magazine hopper 20 for storage. The structure is simple and the cost is low. Only one person is needed to periodically unload and re-inspect the NG, saving time and cost, thus reducing the overall production cost.

[0069] Fourth, by utilizing digital acquisition and control, and information feedback transmitted through sensor signals, the correct position of the conveyor line 10 during transmission is ensured.

[0070] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
