Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing equipment technology, and in particular to an automatic nozzle removal device for a negative pressure lithium battery formation equipment. Background Technology

[0002] Formation is the process of charging the battery with a small current after electrolyte injection, allowing the lithium-ion battery to form a stable electrochemical system. During the production of prismatic lithium batteries, the negative pressure system of the formation equipment draws negative pressure from the battery's electrolyte injection port. As the first point of entry for the electrolyte into the negative pressure system and the component that directly contacts the battery, the nozzle is prone to electrolyte crystallization and blockage, as well as long-term corrosion and wear. Therefore, it is necessary to periodically remove used nozzles and replace them with new ones.

[0003] The patent CN213380132U, which was authorized after the announcement, discloses a tooling for replacing the nozzle of a lithium battery formation equipment, including: a tooling tray; a nozzle carrier, which is disposed on the tooling tray and is used to carry the nozzle; and a clamping mechanism, which is disposed on the tooling tray and has a first state of positioning the nozzle and the nozzle carrier on the tooling tray, and a second state of releasing the positioning of the nozzle and the nozzle carrier. The clamping mechanism includes an actuator and a clamping body driven by the actuator, and the clamping bodies are two symmetrically disposed on both sides of the nozzle.

[0004] The aforementioned tooling change utilizes an actuator and a clamping body to form a clamping mechanism, which is used to assemble and disassemble the suction nozzles. When the chemical formation equipment is upgraded or the number of channels changes, the number of negative pressure suction nozzles on the negative pressure assembly and corresponding to the negative pressure cup of the chemical formation equipment also changes, and the spacing between the negative pressure cup and the negative pressure suction nozzles also changes accordingly. However, the aforementioned clamping mechanism is fixedly arranged on the tooling tray, and its position cannot be changed, making it unable to adapt to changes in the number and position of the suction nozzles. The existing common solution is to pre-set slots or positioning holes with fixed spacing on the equipment, and then manually move the clamping mechanism to the corresponding position. When the number of channels decreases, the excess tongue assembly is removed; when the number of channels increases, the tongue assembly is added. This operation is inconvenient and inefficient. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic nozzle removal device for a lithium battery formation negative pressure equipment, so as to solve the problems in the prior art where existing replacement fixtures cannot adapt or have low replacement efficiency and inconvenient operation when the number and position of nozzles change.

[0006] To achieve the above objectives, the present invention provides an automatic nozzle removal device for a lithium battery formation negative pressure equipment, including a base, a nozzle removal assembly disposed on the base, and a power system for driving the nozzle removal assembly to rise and fall. The nozzle removal assembly has a clamping state of radially clamping the nozzle at a high point and a removing state of removing the nozzle at a low point during the lifting stroke.

[0007] The suction nozzle assembly includes a pair of suction nozzle bases arranged on the base. Each suction nozzle base has a tongue assembly, which includes a suction nozzle tongue. The suction nozzle tongues of the two sets of tongue assemblies are symmetrically arranged to clamp the suction nozzles. The suction nozzle tongue is a plate-shaped structure extending along the arrangement direction of the suction nozzles. There is a clamping space between the two sets of suction nozzle tongues to clamp multiple suction nozzles along the arrangement direction of the suction nozzles.

[0008] Preferably, the tongue assembly further includes fixing blocks spaced apart on the suction nozzle base along the arrangement direction of the suction nozzle. Both ends of the suction nozzle tongue are rotatably mounted on the fixing blocks. The rotation center line of the suction nozzle tongue is perpendicular to the lifting direction of the suction nozzle assembly. The suction nozzle tongue has a first state of rotating downward to an inclined state to be fitted onto the outside of the suction nozzle and a second state of rotating to a horizontal state to be fitted with the suction nozzle downward to stop it. A torsion spring is also provided between the suction nozzle tongue and the fixing blocks to drive the suction nozzle tongue to remain in the second state.

[0009] Preferably, a limiting rod is also arranged on the suction nozzle tongue. When the suction nozzle tongue rotates to the second state, the limiting rod is circumferentially anti-rotationally assembled with the fixing block, and the torsion spring is assembled between the fixing block and the limiting rod.

[0010] Preferably, the base is provided with a slot extending along the direction perpendicular to the arrangement of the suction nozzles, a guide slider is guided in the slot, the suction nozzle base is fixedly assembled with the guide slider, and the slot is also provided with a scale value.

[0011] Preferably, the base includes a base plate and a guide shaft vertically arranged on the base plate. A lifting beam is also guided and mounted on the guide shaft. The power system is connected to the lifting beam to drive the lifting beam to move vertically. Two sets of lifting beams are arranged at intervals along the arrangement direction of the suction nozzles. The suction nozzle assembly is arranged between the two sets of lifting beams.

[0012] Preferably, the power system includes a drive assembly, a support beam, a translation push plate, a lifting ramp, and a linear guide rail. The support beam is arranged between the base plate and the lifting beam and is parallel to the lifting beam. The linear guide rail is arranged on the support beam. The translation push plate is slidably mounted on the linear guide rail. The lifting ramp is fixedly arranged on the translation push plate. The lifting ramp is provided with a driving ramp surface, which extends along the direction of the linear guide rail. The bottom of the lifting beam is provided with rollers supported on the driving ramp surface. The drive assembly is connected to the translation push plate in a transmission manner.

[0013] The power system also includes an elastic reset assembly disposed on the suction nozzle base, the elastic reset assembly being used to connect to the formation equipment and provide a downward elastic force to the suction nozzle assembly.

[0014] Preferably, the drive assembly includes a motor, a translation beam, and a lead screw. The output end of the motor is connected to the lead screw via a synchronous pulley and a synchronous belt. A bearing seat is fixedly mounted on the base plate via a pad. The lead screw is rotatably mounted on the bearing seat. The translation beam is threadedly assembled with the lead screw.

[0018] Compared with the prior art, the automatic nozzle removal device for a lithium battery formation negative pressure equipment according to this invention has the following advantages: the power system drives the nozzle removal assembly to move between a radial clamping state and a removal state. When removing the nozzle, the tongue assembly on the nozzle removal base clamps the nozzle using the nozzle removal tongue. The nozzle removal tongue is a plate-shaped structure extending along the arrangement direction of the nozzles, and there is a clamping space between the nozzle removal tongues to clamp multiple nozzles. Therefore, multiple nozzles can be clamped simultaneously between two nozzle removal tongues on a set of nozzle removal assemblies. When the formation equipment is changed, causing changes in the number and position of the nozzles, the clamping space of the nozzle removal tongue can compensate for the changes in the position and number of nozzles. That is, the nozzles only change within the clamping space, so there is no need to adjust or replace the nozzle removal assembly, saving the workload of operators and improving the adaptability of the nozzle removal device.

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0034] A preferred embodiment of the automatic nozzle removal device for a lithium battery formation negative pressure equipment according to the present invention, such as... Figures 1 to 13 As shown, the automatic nozzle removal device of the lithium battery formation negative pressure equipment includes a base 1, a nozzle removal assembly 2, and a power system 4. The base 1 is the foundation of the entire device, used to support all components and mounting parts, including the nozzle removal assembly 2 and the power system 4. The nozzle removal assembly 2 is used to remove the nozzle 7 from the formation equipment, and the power system 4 is used to drive the nozzle removal assembly 2 to complete the action of removing the nozzle 7.

[0035] The nozzle removal assembly 2 is vertically and vertically mounted on the base 1. The power system 4 is connected to the nozzle removal assembly 2 to drive it to move vertically up and down. During its lifting stroke, the nozzle removal assembly 2 has a clamping state where it radially clamps the nozzle 7 at a high point and a removing state where it removes the nozzle 7 at a low point. When it is necessary to replace the nozzle 7, the power system 4 drives the nozzle removal assembly 2 to move upward to the highest point of its stroke, at which point the nozzle removal assembly 2 radially clamps the nozzle 7, and the nozzle removal assembly 2 is in the clamping state. Then, the power system 4 drives the nozzle removal assembly 2 to move downward to the lowest point of its stroke. During this process, the nozzle removal assembly 2 moves the nozzle 7 downward, thereby pulling the nozzle 7 out of the formation equipment, and the nozzle removal assembly 2 is in the removing state.

[0036] The suction nozzle assembly 2 includes a pair of suction nozzle bases 21 arranged on a base 1, which supports the suction nozzle bases 21. Each suction nozzle base 21 is provided with a tongue assembly 3, and the two sets of tongue assemblies 3 on the two sets of suction nozzle bases 21 clamp and fix the suction nozzle 7 in the radial direction. The tongue assemblies 3 on the two sets of suction nozzle bases 21 have the same structure; only one example is described here.

[0037] The tongue assembly 3 includes a suction nozzle tongue 31. The suction nozzle tongues 31 of the two sets of suction nozzle bases 21 are symmetrically arranged and are located on both sides of the suction nozzle 7 when the suction nozzle 7 is removed, so as to achieve radial clamping and fixation of the suction nozzle 7. The suction nozzle tongue 31 is a plate-shaped structure extending along the arrangement direction of the suction nozzle 7. The arrangement direction of the suction nozzle 7 is the length direction of the entire device, and the width direction of the device is the direction perpendicular to the arrangement direction of the suction nozzle 7 in the horizontal plane.

[0038] There is a clamping space between the two sets of suction nozzle tongues 31 that clamps multiple suction nozzles 7 along the arrangement direction of the suction nozzles 7. Since the suction nozzle tongues 31 are plate-shaped structures, they are continuous in the arrangement direction of the suction nozzles 7. Therefore, the clamping space is a continuous space, and multiple suction nozzles 7 are arranged in the clamping space at the same time. The suction nozzle tongues 31 of the two sets of suction nozzle bases 21 can clamp multiple suction nozzles 7 at the same time.

[0039] When the chemical forming equipment is changed or the number of channels is changed, the number and position of the suction nozzles 7 change, and the distance between the two suction nozzles 7 also changes. At this time, the number and position of the suction nozzles 7 in the clamping space on the suction nozzle tongue 31 change, but the suction nozzle tongue 31 itself does not need to be adjusted or replaced to clamp the suction nozzles 7, which is highly adaptable.

[0040] Specifically, two consecutively distributed tongue assemblies 3 are provided on the same suction nozzle base 21 along the arrangement direction of the suction nozzles 7. The two tongue assemblies 3 are arranged parallel to each other along the length direction of the base 1. The tongue assemblies 3 on the paired suction nozzle base 21 are still symmetrically arranged. When the number of suction nozzles 7 in the formation equipment changes, the length of the formation equipment itself does not change. The symmetrically arranged suction nozzle tongues 31 can still radially clamp and fix the suction nozzles 7 in the entire arrangement direction. In other embodiments, only one tongue assembly 3 may be provided on the same suction nozzle base 21 along the arrangement direction of the suction nozzles 7, or three or four tongue assemblies 3 may be provided.

[0041] Specifically, two sets of paired suction nozzle bases 21 are arranged on the base 1 along its width. The two sets of paired suction nozzle bases 21 can remove two rows of suction nozzles 7 simultaneously, improving the removal efficiency of the suction nozzles 7. The structures of the two sets of paired suction nozzle bases 21 are the same, and will not be described again here; in other embodiments, the number of paired suction nozzle bases 21 can be increased according to the distribution position of the suction nozzles 7.

[0042] When removing the nozzle, the tongue assembly 3 on the nozzle removal base 21 clamps the nozzle 7 using the nozzle removal tongue 31. Therefore, multiple nozzles 7 can be clamped simultaneously between the two nozzle removal tongues 31 on a set of nozzle removal assemblies 2. When the chemical forming equipment is changed, causing changes in the number and position of the nozzles 7, the clamping space of the nozzle removal tongue 31 can compensate for the changes in the position and number of nozzles 7. That is, the nozzles 7 only change within the clamping space. Therefore, it is not necessary to adjust or replace the nozzle removal assembly 2, which saves the workload of the operator. It is also not necessary to pre-process the slots 23 with fixed spacing and number, which saves manufacturing costs and improves the adaptability of the nozzle removal device.

[0043] Preferably, the tongue assembly 3 further includes fixing blocks 32 arranged at intervals on the suction nozzle base 21 along the arrangement direction of the suction nozzle 7. Both ends of the suction nozzle tongue 31 are rotatably mounted on the fixing blocks 32. The rotation center line of the suction nozzle tongue 31 is perpendicular to the lifting direction of the suction nozzle assembly 2. The suction nozzle tongue 31 has a first state of rotating downward to an inclined state to be fitted on the outside of the suction nozzle 7 and a second state of rotating to a horizontal state to be mounted downward to stop the suction nozzle 7. A torsion spring 33 is also provided between the suction nozzle tongue 31 and the fixing blocks 32 to drive the suction nozzle tongue 31 to be held in the second state.

[0044] The suction nozzle tongue 31 is rotatably mounted on the fixed block 32. The suction nozzle tongue 31 can switch between a first state and a second state during rotation. In the second state, the distance between the two sets of suction nozzle tongues 31 arranged opposite each other is smaller than the bottom dimension of the suction nozzle 7. In the first state, the distance between the two sets of suction nozzle tongues 31 is larger than the bottom dimension of the suction nozzle 7, allowing the suction nozzle 7 to pass between the two sets of suction nozzle tongues 31, so that the suction nozzle base 21 moves upward to the clamping state.

[0045] The rotation center line of the suction nozzle tongue 31 is perpendicular to the lifting direction of the suction nozzle assembly 2. When the suction nozzle base 21 moves upward, the suction nozzle 7 presses against the suction nozzle tongue 31, and the suction nozzle tongue 31 rotates downward to the first state. When the suction nozzle base 21 moves to the highest point and is in a clamping state, under the action of the torsion spring 33, the suction nozzle tongue 31 rotates to a horizontal state. At this time, the suction nozzle tongue 31 is in the second state and blocks the suction nozzle 7 downward. During the process of the power system 4 driving the suction nozzle assembly 2 to move downward to the removal state, the suction nozzle tongue 31 drives the suction nozzle 7 to move downward, thereby removing the suction nozzle 7.

[0046] The suction nozzle tongue 31 is rotatably assembled with the fixing block 32 and subjected to elastic force by a torsion spring 33. This eliminates the need for electrical control of the suction nozzle tongue 31's movement, simplifying the structure of the suction nozzle tongue 31 clamping the suction nozzle 7. Specifically, in this embodiment, the fixing block 32 has a rotating hole, within which a rotating shaft 34 is fitted. The suction nozzle tongue 31 is fixedly mounted on the rotating shaft 34, and the torsion spring 33 is fitted onto the rotating shaft 34 and engaged between the fixing block 32 and the suction nozzle tongue 31, providing power for the tongue 31 to reset after rotation.

[0047] Preferably, in this embodiment, a guide slope is provided on the opposite side of the paired suction nozzle tongues 31. The bottom ends of the guide slopes are close to each other, and the top ends are far apart, so that a V-shaped cut is formed between the two sets of suction nozzle tongues 31. When the suction nozzle assembly 2 moves upward to the clamping state, the bottom of the suction nozzle 7 presses against the guide slope, reducing the resistance between the suction nozzle 7 and the suction nozzle tongues 31, making it easier for the suction nozzle tongues 31 to rotate downward to the first state.

[0048] Preferably, a limiting rod 35 is also arranged on the suction nozzle tongue 31. When the suction nozzle tongue 31 rotates to the second state, the limiting rod 35 is circumferentially anti-rotationally assembled with the fixing block 32, and the torsion spring 33 is assembled between the fixing block 32 and the limiting rod 35.

[0049] A limiting rod 35 is arranged on the suction nozzle tongue 31. After the limiting rod 35 is axially anti-rotated with the fixing block 32, the rotation direction of the suction nozzle tongue 31 can be limited, so that when the suction nozzle tongue 31 rotates upward, it can only rotate to the second state. When the power system 4 drives the suction nozzle assembly 2 to move downward, the suction nozzle 7 applies an upward force to the suction nozzle tongue 31, which tends to drive the suction nozzle tongue 31 to rotate upward. At this time, the suction nozzle tongue 31 is anti-rotated by the limiting rod 35 and the fixing block 32, ensuring that the suction nozzle tongue 31 and the suction nozzle 7 are stopped downward. When the suction nozzle assembly 2 moves to the removal state, the suction nozzle tongue 31 can simultaneously remove the suction nozzle 7.

[0050] Preferably, the base 1 is provided with a slot 23 extending in a direction perpendicular to the arrangement of the nozzles 7, and a guide slider 22 is guided and assembled in the slot 23. The nozzle base 21 is fixedly assembled with the guide slider 22, and the slot 23 is also provided with a scale value 24.

[0051] The slot 23 extends perpendicular to the arrangement direction of the nozzle 7, that is, the slot 23 extends along the width direction of the entire device. The guide slider 22 can slide in the slot 23. The guide slider 22 is fixedly connected to the nozzle base 21 by bolts. After loosening the fastening bolts, the guide slider 22 can move in the slot 23, which simultaneously drives the nozzle base 21 to move in the width direction of the base 1, thereby adjusting the position of the nozzle assembly 2 on the base 1.

[0052] The slot 23 is set with a scale value 24. When the guide slider 22 and the suction nozzle base 21 move in the slot 23, the scale value 24 can indicate the specific position of the suction nozzle assembly 2 during movement and adjustment.

[0053] Preferably, the base 1 includes a base plate 11 and a guide shaft 12 vertically arranged on the base plate 11. A lifting beam 13 is also guided and assembled on the guide shaft 12. The power system 4 is connected to the lifting beam 13 to drive the lifting beam 13 to move vertically. Two sets of lifting beams 13 are arranged at intervals along the arrangement direction of the suction nozzles 7. The suction nozzle assembly 2 is arranged between the two sets of lifting beams 13.

[0054] The base 1 consists of a base plate 11, a guide shaft 12, and a lifting beam 13, simplifying the structure of the base 1. The two ends of the suction nozzle assembly 2 are supported on the two sets of lifting beams 13 to ensure the stability of the suction nozzle assembly 2. When the power system 4 drives the lifting beams 13 to rise and fall, the vertical position of the suction nozzle assembly 2 can be adjusted, allowing the suction nozzle assembly 2 to switch between the clamping state and the removal state.

[0055] Specifically, a housing 15 is also arranged on the base plate 11, which covers the entire perimeter of the device and serves for internal protection and decoration. Electrical components are also arranged on the base 1 for power supply, signal transmission, logic control, and automatic detection.

[0056] Preferably, the power system 4 includes a drive assembly 5, a support beam 41, a translation push plate 42, a lifting inclined block 43, and a linear guide rail 44. The support beam 41 is arranged between the base plate 11 and the lifting beam 13 and is arranged parallel to the lifting beam 13. The linear guide rail 44 is arranged on the support beam 41. The translation push plate 42 is slidably mounted on the linear guide rail 44. The lifting inclined block 43 is fixedly arranged on the translation push plate 42. The lifting inclined block 43 is provided with a driving inclined surface, which extends along the direction of the linear guide rail 44. The bottom of the lifting beam 13 is provided with a roller 45 supported on the driving inclined surface. The drive assembly 5 is connected to the translation push plate 42 in a transmission manner.

[0057] The power system 4 also includes an elastic reset assembly 6 arranged on the suction nozzle base 21, which is used to connect to the formation equipment and provide a downward elastic force to the suction nozzle assembly 2.

[0058] In this embodiment, a column is vertically arranged on the base plate 11, and a supporting beam 41 is fixedly mounted on the top of the column. The supporting beam 41 extends along the width direction of the base plate 11 and is arranged parallel to the base plate 11. The linear guide rail 44 includes a slide rail and a slider. The slide rail is fixedly mounted on the upper surface of the supporting beam 41, and the slider can move freely along the slide rail. The slider is also fixedly mounted on the bottom of the translation push plate 42. The power system 4 is connected to the translation push plate 42 and can push the translation push plate 42 to slide along the width direction of the device. The translation push plate 42 drives the slider to move synchronously on the slide rail. When the translation push plate 42 moves, the roller 45 can roll freely along the upper surface of the driving inclined plane, thereby driving the lifting beam 13 to rise and fall synchronously.

[0059] The lifting beam 13 is moved by a translation push plate 42, a lifting inclined block 43 and a roller 45, avoiding the direct drive of the lifting beam 13 by the drive component 5. By controlling the amount of movement of the translation push plate 42, the lifting displacement of the lifting beam 13 can be precisely adjusted, and the vertical position of the suction nozzle component 2 can be adjusted.

[0060] The elastic reset component 6 is arranged on the suction nozzle base 21. The elastic reset component 6 provides a downward elastic force to the suction nozzle assembly 2, providing power for the suction nozzle assembly 2 to move from the clamped state to the removed state. When the drive component 5 drives the lifting beam 13 and the suction nozzle assembly 2 to move upward, the elastic reset component 6 generates an elastic force. When the suction nozzle assembly 2 moves downward, the elastic force is released, and the suction nozzle 7 and the suction nozzle tongue 31 provide resistance. The elastic force is greater than the resistance, thus removing the suction nozzle 7. By utilizing the elastic reset component 6, the suction nozzle 7 is automatically removed when the suction nozzle assembly 2 moves downward, eliminating the need for frequent opening and closing of the formation equipment and the weight of the device to remove the suction nozzle 7.

[0061] Preferably, the drive assembly 5 includes a motor 51, a translation beam 52, and a lead screw 53. The output end of the motor 51 and the lead screw 53 are connected to the synchronous belt 55 via a synchronous pulley 54. A bearing seat 56 is fixedly mounted on the base plate 11 via a pad 57. The lead screw 53 is rotatably mounted on the bearing seat 56. The translation beam 52 is threadedly assembled with the lead screw 53. Both ends of the translation beam 52 are fixedly connected to the translation push plate 42.

[0062] The translation beam 52 and the lead screw 53 form a lead screw and nut mechanism. The lead screw 53 extends parallel to the base plate 11 and along the width direction of the base plate 11. The lead screw 53 is rotatably mounted on the bearing seat 56 and can rotate freely around its axis. The bearing seat 56 is fixedly mounted on the pad 57 on the base plate 11, so that the lead screw 53 can only rotate and cannot move axially. A synchronous pulley 54 is fixedly mounted on one axial end of the lead screw 53, which is connected to the synchronous pulley 54 fixedly mounted on the motor 51 through a synchronous belt 55. The power output of the motor 51 is transmitted to the lead screw 53 through the synchronous belt 55, driving the lead screw 53 to rotate.

[0063] When the lead screw 53 rotates, it drives the translation beam 52 to move along the axis of the lead screw 53 through the threaded structure. The two ends of the translation beam 52 are connected to the translation push plates 42 on the two sets of support beams 41 respectively, thereby driving the translation push plates 42 to move synchronously, so that the two sets of lifting beams 13 rise and fall synchronously.

[0064] Preferably, the elastic reset assembly 6 includes a compression spring 61, a spring block 62, and an equalizing bolt 63. The compression spring 61 is arranged on the suction nozzle base 21, the top of the compression spring 61 is provided with the spring block 62, and the equalizing bolt 63 is connected between the spring block 62 and the suction nozzle base 21.

[0065] The spring block 62 is connected to the suction nozzle base 21 by an equal-height bolt 63. The equal-height bolt 63 passes through the spring block 62 and the compression spring 61 in sequence and is fixedly connected to the suction nozzle base 21, thereby fixing the compression spring 61. In this embodiment, each suction nozzle base 21 has an elastic reset component 6 arranged at both ends to ensure that the suction nozzle assembly 2 is subjected to balanced forces.

[0066] Preferably, linear bearings 14 are arranged at both ends of the lifting beam 13, and the linear bearings 14 are fitted on the outside of the guide shaft 12.

[0067] The two ends of the lifting beam 13 are guided and assembled with the guide shaft 12 by linear bearings 14. The linear bearings 14 are sleeved on the guide shaft 12 and can slide left and right and up and down along the guide shaft 12, which can reduce the resistance between the lifting beam 13 and the guide shaft 12, so that the lifting beam 13 moves smoothly.

[0068] Preferably, a material box 16 for temporarily storing the suction nozzle 7 is also arranged on the base 1, and the material box 16 is arranged below the suction nozzle assembly 2.

[0069] A material box 16 is arranged below the nozzle removal assembly 2. The material box 16 extends along the length of the device and can be used to collect the removed nozzles 7. In this embodiment, there are two sets of material boxes 16, which are arranged at intervals along the width direction and are arranged below the two sets of nozzle removal assemblies 2.

[0070] The working process of this invention is as follows:

[0071] When it is necessary to remove the suction nozzle 7, the motor 51 drives the lead screw 53 to rotate on the bearing seat 56 through the synchronous pulley 54 and the synchronous belt 55. The translation beam 52 moves axially on the lead screw 53, thereby driving the translation push plates 42 at both ends to move along the width direction of the device on the linear guide rail 44. When the translation push plate 42 moves, the roller 45 rolls freely on the driving inclined surface on the upper surface of the lifting inclined block 43. Under the action of the driving inclined surface, the roller 45 rolls and drives the lifting beam 13 to slide upward on the guide shaft 12, thereby driving the suction nozzle removal assembly 2 to move upward.

[0072] When the suction nozzle assembly 2 moves upward, the spring block 62 contacts the corresponding position on the chemical formation equipment. The spring block 62 compresses the spring 61 to generate elastic force. At the same time, the bottom end of the suction nozzle 7 contacts the guide slope on the suction nozzle tongue 31, pressing the suction nozzle tongue 31 to rotate downward around the rotation axis 34. The suction nozzle tongue 31 overcomes the force of the torsion spring 33 and rotates from the second state to the first state. When the suction nozzle assembly 2 moves to the clamping state, the suction nozzle tongue 31 rotates to the horizontal and is in the second state under the action of the torsion spring 33. At this time, the limit rod 35 and the fixing block 32 are anti-rotation assembled.

[0073] Motor 51 rotates in the opposite direction and drives the lifting beam 13 and the suction nozzle assembly 2 to move downward along the guide shaft 12. The suction nozzle tongue 31 stops the suction nozzle 7. Under the action of the limit rod 35, the suction nozzle tongue 31 cannot rotate upward and drive the suction nozzle 7 to move downward. The elastic force of the compression spring 61 is released and is greater than the resistance of the suction nozzle 7 to the suction nozzle tongue 31. Under the action of the elastic force, the suction nozzle tongue 31 removes the suction nozzle 7 from the chemical formation equipment. The removed suction nozzle 7 falls into the feed box 16, completing the removal of the suction nozzle 7.

[0074] In summary, this invention provides an automatic nozzle removal device for a lithium battery formation negative pressure equipment. Its power system drives the nozzle removal assembly to move between a radial clamping state and a removal state. During nozzle removal, the tongue assembly on the nozzle removal base clamps the nozzle using the nozzle removal tongue. The nozzle removal tongue is a plate-shaped structure extending along the nozzle arrangement direction, and there is a clamping space between the nozzle removal tongues to hold multiple nozzles. Therefore, multiple nozzles can be clamped simultaneously between two nozzle removal tongues on a set of nozzle removal assemblies. When the formation equipment is changed, causing changes in the number and position of nozzles, the clamping space of the nozzle removal tongue can compensate for the changes in the position and number of nozzles. That is, the nozzles only change within the clamping space, thus eliminating the need to adjust or replace the nozzle removal assembly, saving the operator's workload and improving the adaptability of the nozzle removal device.

[0075] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
