Description

Technical Field

[0001] The invention relates to the field of lithium battery processing, and in particular to a fully automatic lithium battery vortex tube heating, refrigeration and drying production line system. Background Art

[0002] In the heating, cooling and drying process of lithium battery production, the existing heating and cooling equipment production line has many defects that are difficult to ignore.

[0003] From the perspective of efficiency, the heating and cooling speeds of existing production lines are far from matching the growing production needs. Taking the heating process as an example, traditional heating devices mostly use heating wires, and their main method of heat transfer is heat conduction. When faced with large-scale lithium battery production, the heat is transferred from the heating wires to each battery cell. Not only is the path long, but the heat loss is also large during the transfer process. This makes the entire heating process extremely time-consuming, seriously slowing down the pace of production. The refrigeration aspect is also not optimistic. Traditional compressor refrigeration systems need to go through complex compression, condensation, throttling, and evaporation cycles. Each startup requires a certain amount of time to establish a stable refrigeration cycle. It is almost impossible to meet the process requirements on the production line that require rapid switching of heating and cooling states.

[0004] Existing production lines also perform poorly in terms of temperature control accuracy and uniformity. Due to the design limitations of the heating and cooling devices, it is difficult to ensure that each lithium battery is evenly heated or cooled during the production process. In large heating or cooling spaces, there are obvious gradient differences in temperature distribution, resulting in different degrees of heating or cooling of lithium batteries in different locations, which directly affects the consistency and quality stability of the batteries.

[0005] In addition, the existing production lines have a low degree of automation and rely heavily on manual operations. Human participation is required in material handling, temperature adjustment, equipment monitoring and other links, which not only increases labor costs but also introduces human errors. The timeliness and accuracy of manual operations are difficult to guarantee. When the production pace is accelerated, operational errors are prone to occur, which in turn affects product quality and production efficiency.

[0006] In summary, the defects of the existing heating and cooling device production line have seriously restricted the development of the lithium battery industry. To this end, we need to design a new, efficient and intelligent production line system to break this dilemma. Summary of the invention

[0007] Based on this, it is necessary to provide a fully automatic lithium battery vortex tube heating, cooling and drying production line system to address the existing technical problems.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] refer to Figures 1 to 10 A fully automatic lithium battery vortex tube heating, cooling and drying production line system includes a feeding mechanism 2 for driving a battery rack 10 to move, and also includes:

[0042] A plurality of heating chambers 7 connected to the heating output ends of the vortex tubes 3;

[0043] A refrigeration chamber 8 is arranged beside the heating chamber 7 and is connected to the refrigeration output ends of the vortex tubes 3;

[0044] A manipulator 1 is arranged beside the feeding mechanism 2, and the manipulator 1 inserts a plurality of lithium batteries 9 into the battery rack 10 one by one in sequence;

[0045] A three-axis moving mechanism 4 is arranged beside the manipulator 1. The output end of the three-axis moving mechanism 4 is fixedly connected to two gripper cylinders 5. The three-axis moving mechanism 4 puts the battery rack 10 filled with lithium batteries 9 into the heating chamber 7 and the cooling chamber 8 one by one;

[0046] A plurality of chassis 12 are fixedly connected to the middle of the lower ends of the plurality of battery racks 10;

[0047] A plurality of tightening mechanisms are respectively connected to the plurality of heating chambers 7 and the refrigeration chambers 8, each of the tightening mechanisms comprises a top plate 22, four tightening arc plates 34 and two tightening handles 24, the top plate 22 is rotatably connected to the bottom plates inside the plurality of heating chambers 7 and the refrigeration chambers 8, the four tightening arc plates 34 are respectively arranged at the upper end of the top plate 22 and can tighten the bottom plate 12, and the two tightening handles 24 are symmetrically arranged on both sides of the top plate 22;

[0048] The spoiler mechanisms are respectively connected to the plurality of heating chambers 7 and the refrigeration chambers 8 and are arranged above the corresponding top plates 22 . Each spoiler mechanism includes a plurality of spoiler plates 46 .

[0049] When the device is in operation, the loading mechanism 2 moves the battery rack 10 to the side of the manipulator 1 in sequence, and the manipulator 1 places a number of lithium batteries 9 on the unloaded battery rack 10 in sequence. Then the three-axis moving mechanism 4 moves along the track to the side of the manipulator 1 and drives the battery rack 10 fully loaded with lithium batteries 9 to move.

[0050] When the battery rack 10 fully loaded with lithium batteries 9 moves to the side of the heating chamber 7, the three-axis moving mechanism 4 will place the battery rack 10 inside the heating chamber 7 until the chassis 12 at the lower end of the battery rack 10 and the top plate 22 inside the heating chamber 7 are coaxially engaged and connected, and then the two clamping claw cylinders 5 connected to the output end of the three-axis moving mechanism 4 will push the two clamping handles 24 on the top plate 22 to move (similarly, when unlocking, the two clamping claw cylinders 5 will pull the two clamping handles 24 on the top plate 22 and unlock the top plate 22), ensuring that the clamping handles 24 can drive the corresponding clamping arc plates 34 to clamp the chassis 12 (the specific driving process is described in detail later), thereby preventing the chassis 12 and the top plate 22 from slipping when the top plate 22 rotates.

[0051] During the heating (or cooling) process, the pressing mechanism will drive the top plate 22 to rotate (the specific rotation process will be described in detail later), ensuring that the plurality of lithium batteries 9 can be fully heated (or cooled) as the battery rack 10 rotates. Since the heating chamber 7 and the cooling chamber 8 in the present device are both operated based on the vortex tube 3, the heating (or cooling) airflow in the vortex tube 3 needs to be moved under the action of the spoiler mechanism. At this time, if the spoiler plate 46 breaks the laminar state of the air, the heat convection effect is enhanced, the air around the lithium battery 9 is continuously renewed, and the heat exchange efficiency is improved.

[0052] After the heating is completed, the three-axis moving mechanism 4 takes out the battery rack 10 in the heating chamber 7 and transfers it to the refrigeration chamber 8, thereby completing the drying of the lithium battery 9.

[0053] In order to facilitate the three-axis moving mechanism 4 to drive the battery rack 10 to move, the following features are also specifically provided:

[0054] A fork frame 6 is fixedly connected to both sides of the output end of the three-axis moving mechanism 4, and an oblique handle 11 is fixedly connected to both sides of the battery rack 10. When the three-axis moving mechanism 4 drives the battery rack 10 to move, the fork frame 6 abuts against the lower end of the corresponding oblique handle 11. When the three-axis moving mechanism 4 is in operation, the fork frame 6 at its output end will accurately contact the lower ends of the oblique handles 11 on both sides of the battery rack 10. Relying on this abutment relationship, the fork frame 6 can stably drive the battery rack 10 to move, avoiding shaking or falling off of the battery rack 10 during transportation, and ensuring the stability and safety of the battery 9 during transportation.

[0055] In order to facilitate the snap connection between the bottom plate 12 and the top plate 22, the following features are also provided:

[0056] Two limiting grooves 13 are formed at the lower end of the chassis 12, and two limiting flanges 23 are formed at the upper end of the top plate 22. The limiting flanges 23 and the limiting grooves 13 are slidably matched. When the three-axis moving mechanism 4 puts the battery rack 10 filled with lithium batteries 9 into the heating chamber 7 or the cooling chamber 8, the limiting grooves 13 at the lower end of the chassis 12 will quickly align and engage with the limiting flanges 23 at the upper end of the top plate 22, so as to realize the precise and detachable connection between the chassis 12 and the top plate 22. This connection method is convenient and fast, and can ensure that the relative positions of the two are fixed during the subsequent operation, preventing the battery rack 10 from being displaced.

[0057] In order to drive the top plate 22 to rotate so that the lithium batteries 9 can fully contact with the temperature-variable airflow, the following features are also specifically provided:

[0058] The tightening mechanism also includes an active motor 15, a first bevel gear 16, a second bevel gear 17, a first pulley 18, a second pulley 19, a driving gear 20 and a driving sprocket 21. The outer walls of the heating chamber 7 and the refrigeration chamber 8 are respectively fixedly connected to the active motor 15. The first bevel gear 16 is coaxially fixedly connected to the output end of the active motor 15. The second bevel gear 17 is rotatably arranged on the side of the first bevel gear 16 through the bevel gear rack and meshes with the first bevel gear 16. The first pulley 18 is coaxially fixedly connected to the second bevel gear 17. The second pulley 19 is transmission-connected to the first pulley 18 through a steel belt. The driving sprocket 21 is coaxially fixedly connected to the top plate 22. The driving gear 20 meshes with the driving sprocket 21 and is coaxially fixedly connected to the second pulley 19. The first pulley 18 is a first output end of the tightening mechanism. After the active motor 15 is started, its output end drives the first bevel gear 16 to rotate, and the first bevel gear 16 drives the second bevel gear 17 meshing therewith to rotate, thereby driving the first pulley 18 to rotate. Through the steel belt transmission, the second pulley 19 also rotates accordingly, and the second pulley 19 drives the driving gear 20 to rotate, and the driving gear 20 meshes with the driving gear plate 21, thereby driving the top plate 22 to rotate, so that the lithium battery 9 placed on the battery rack 10 can fully contact the variable temperature airflow in the heating chamber 7 or the refrigeration chamber 8, thereby improving the heating or cooling effect.

[0059] In order to provide power for the displacement of the abutting arc plate 34, the following features are also specifically provided:

[0060] The pressing mechanism further includes two pressing push plates 25, two pressing racks 26 and four driven gears 27. The two pressing push plates 25 are respectively slidably connected to the top plate 22, and the pressing push plates 25 are fixedly connected to the pressing handle 24 (such as Fig. 9 As shown, in order to facilitate the display of detailed structure, Fig. 9 The middle tightening push plate 25 and the tightening handle 24 are in an exploded view), the two tightening racks 26 are respectively fixedly connected to the two tightening push plates 25, and the four driven gears 27 are respectively arranged on the side of the four tightening arc plates 34 away from the center of the top plate 22. The driven gears 27 are meshed with the adjacent tightening racks 26, and the driven gears 27 are the second output end of the tightening mechanism. When the clamping cylinder 5 pushes the tightening handle 24 to move, the tightening handle 24 drives the tightening push plate 25 to slide on the top plate 22, the tightening push plate 25 drives the tightening rack 26 to move, and the tightening rack 26 drives the driven gear 27 meshed therewith to rotate, and the driven gear 27 then drives the tightening arc plate 34 to move toward the center of the top plate 22 (the specific driving process will be described in detail later), thereby clamping the chassis 12 to ensure the stability of the battery rack 10 during the rotation process.

[0061] In order to realize that when the top plate 22 and the bottom plate 12 are engaged and connected, the pressing spring 33 will push the pressing arc plate 34 to elastically press against the outer edge of the bottom plate 12; and after the clamping claw cylinder 5 pushes the pressing handle 24 to move, the pressing spring 33 can be compressed, so that the pressing arc plate 34 and the bottom plate 12 are changed from non-rigid pressing to rigid pressing, the following features are also provided:

[0062] The tightening mechanism also includes four positioning seats 28, four screw sleeves 29, four screw rods 30, four positioning plates 31, eight positioning slide rails 32 and four tightening springs 33. The four positioning plates 31 are respectively arranged on the side of the four tightening arc plates 34 away from the center of the top plate 22. One end of the four tightening springs 33 is fixedly connected to the four tightening arc plates 34, and the other end is fixedly connected to the four positioning plates 31. The lower end of each positioning plate 31 is respectively provided with two positioning slide rails 32. The positioning slide rails 32 are fixedly connected to the upper end of the top plate 22. The positioning plate 31 is slidably connected to the positioning slide rails 32. The positioning seat 28 is arranged on the side of the positioning plate 31 away from the tightening arc plate 34. The positioning plate 31 is fixedly connected to the top plate 22. The screw sleeve 29 is rotatably connected to the positioning plate 31. The screw sleeve 29 is coaxially fixedly connected to the driven gear 27. One end of the screw rod 30 is threadedly connected to the screw sleeve 29, and the other end is fixedly connected to the positioning plate 31. When the top plate 22 and the bottom plate 12 are engaged, the pressing spring 33 is in a naturally stretched state, pushing the pressing arc plate 34 to elastically press against the outer edge of the bottom plate 12 (such as Figure 8As shown); when the clamping claw cylinder 5 pushes the clamping handle 24 to move, the second output end of the clamping mechanism drives the screw sleeve 29 to rotate, and the screw 30 drives the positioning plate 31 to move under the action of the screw sleeve 29, compressing the clamping spring 33, so that the non-rigid clamping between the clamping arc plate 34 and the chassis 12 is changed to rigid clamping, thereby enhancing the fixing effect.

[0063] In order to supplement the specific structure of the spoiler mechanism, the following features are also specifically set:

[0064] The spoiler mechanism further includes a transfer gear 36, a transfer top seat 37, a transfer gear ring 38 and a power gear ring 39. The transfer gear 36 is coaxially fixedly connected to the first pulley 18. The transfer top seat 37 is arranged above the top plate 22. The transfer gear ring 38 is meshed with the transfer gear 36 and is rotatably connected to the transfer top seat 37. The power gear ring 39 is coaxially fixedly connected to the transfer gear ring 38 and is rotatably connected to the transfer top seat 37. When the first pulley 18 rotates and drives the transfer gear 36 to rotate, the transfer gear 36 drives the transfer gear ring 38 meshed therewith to rotate, and the transfer gear ring 38 drives the power gear ring 39 coaxially therewith to rotate, providing rotational power for other components of the subsequent spoiler mechanism, so that the spoiler mechanism can effectively disturb the airflow in the heating chamber 7 or the refrigeration chamber 8.

[0065] In order to supplement the specific structure of the spoiler mechanism, the following features are also specifically set:

[0066] The spoiler mechanism also includes a central turntable 48, a flow-interference gear 40, a plurality of range-increasing gears 41, a flow-interference disc 42, a plurality of connecting pins 43, a flow-interference seat 47, a plurality of connecting pins 43 and a plurality of swinging pull rods 44. The central turntable 48 is arranged below the transfer top seat 37 and is fixedly connected to the transfer top seat 37. The flow-interference seat 47 is arranged in an array of equal angles along the circumferential direction of the transfer top seat 37. The flow-interference seat 47 is fixedly connected to the transfer top seat 37. The flow-interference gears 40 are respectively meshed with the power gear ring 39 and are rotatably connected to the corresponding flow-interference seat 47. , several range-increasing gears 41 are respectively meshed with the flow-interfering gears 40 and are rotatably connected with the corresponding spoiler seats 47, the flow-interfering discs 42 are respectively coaxially fixedly connected with the several range-increasing gears 41, several connecting pins 43 are respectively fixedly connected with the eccentric position of the lower end of the flow-interfering disc 42, several swing rods 44 are respectively arranged at the lower end of the flow-interfering disc 42, one end of several swing rods 44 is hinged to the middle turntable 48, a limiting hole 45 is formed in the middle of the swing rod 44, and several connecting pins 43 are slidably connected with the corresponding limiting holes 45. When the power ring gear 39 rotates, the power ring gear 39 drives the spoiler gear 40 meshing therewith to rotate, the spoiler gear 40 drives the range extender gear 41 to rotate, the range extender gear 41 drives the spoiler disc 42 to rotate, the spoiler disc 42 cooperates with the limiting hole 45 of the swing lever 44 through the connecting pin 43, so that the swing lever 44 swings around the hinge point of the turntable 48, thereby disrupting the laminar state of the airflow in the heating chamber 7 or the refrigeration chamber 8 and enhancing the heat convection effect.

[0067] The working principle of this device is that the feeding mechanism 2 first moves the battery rack 10 to the side of the manipulator 1 in sequence, and the manipulator 1 accurately places the lithium batteries 9 one by one on the unloaded battery rack 10. At this time, the three-axis moving mechanism 4 starts to operate, and the fork frames 6 on both sides of its output end are against the lower ends of the oblique handles 11 on both sides of the battery rack 10, stably driving the battery rack 10 fully loaded with lithium batteries 9 to move. When the battery rack 10 moves to the side of the heating chamber 7 or the refrigeration chamber 8, the three-axis moving mechanism 4 puts the battery rack 10 into the room, and the limiting groove 13 at the lower end of the chassis 12 is quickly engaged with the limiting flange 23 at the upper end of the top plate 22. Subsequently, the clamping claw cylinder 5 pushes the clamping handle 24, and the clamping handle 24 drives the clamping push plate 25 to slide, and then the clamping arc plate 34 clamps the chassis 12 through the clamping rack 26 and the driven gear 27. The active motor 15 starts and drives the top plate 22 to rotate, so that the lithium battery 9 rotates with the battery rack 10. At the same time, the active motor 15 will also drive the transfer gear 36 to rotate. The transfer gear 36 is driven by a series of transmissions such as the transfer gear ring 38, the power gear ring 39, the spoiler gear 40, and the range-extending gear 41, so that the spoiler disc 42 rotates, and the laminar flow state of the airflow in the heating chamber 7 or the cooling chamber 8 is disrupted through the cooperation of the connecting pin 43 and the swinging pull rod 44. In the heating chamber 7, the heating output end of the vortex tube 3 is connected to the heating chamber 7, and the hot air flow continuously exchanges heat with the lithium battery 9 under the action of the spoiler mechanism; in the cooling chamber 8, the cooling output end of the vortex tube 3 is connected to the cooling chamber 8, and the cold air flow also cools down the lithium battery 9 under the action of the spoiler mechanism, thereby realizing the heating, cooling and drying treatment of the lithium battery 9. The whole process has a high degree of automation, and each component works in coordination, which is efficient and stable.

[0068] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
