Description

[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components.

[0045] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0046] As described in the background of this application, in the related art, during the lithium battery formation process, the nozzle that interfaces with the battery filling port on the formation equipment is a consumable part and needs to be replaced regularly. In the related art, a nozzle removal tool is usually used to remove the nozzle for regular replacement.

[0047] Specifically, nozzle extraction tools in related art typically include a clamping jaw assembly and an electromagnet. The clamping jaw assembly is used to clamp the nozzle, and the electromagnet is used to attach to the movable frame of the formation equipment through electromagnetic force. When extracting the nozzle, the upward and downward movement of the movable frame provides the pulling force to remove the nozzle.

[0048] However, because electromagnets are susceptible to temperature, resulting in unstable electromagnetic forces, and because this unstable magnetic force is unevenly distributed across the adsorption surface, compensating for this unevenness requires higher material and flatness requirements for the adsorption surface. These higher material requirements lead to higher manufacturing costs for the formation equipment, while higher flatness requirements necessitate higher manufacturing precision and processes for the equipment, further increasing its manufacturing costs.

[0049] In view of the above-mentioned problems, the present application provides a nozzle extraction tooling to solve the problem of high manufacturing cost of chemical formation equipment due to the use of electromagnetic adsorption in related technologies.

[0050] The technical solution of this application will be further described below with reference to specific embodiments and drawings:

[0051] like Figure 1 and Figure 2 As shown, the nozzle extraction tool includes a tool base 1, a nozzle connection assembly 2, and a structural connection assembly 3. Among them, the nozzle connection assembly 2 is arranged on the tool base 1, and the nozzle connection assembly 2 is used to connect with the nozzle on the chemical formation equipment (not shown in the figure). The structural connection assembly 3 is arranged on the tool base 1, and the structural connection assembly 3 includes a connecting member 31, which is used to connect with a movable member (not shown in the figure) on the chemical formation equipment through a structural connection, so that the movable member can drive the tool base 1 to move to enable the nozzle connection assembly 2 to remove the nozzle.

[0052] In the present application, when the suction nozzle is pulled out using the suction nozzle pulling tool, the suction nozzle connecting component 2 can be connected to the suction nozzle on the formation equipment, and the connecting part 31 in the structural connection component 3 can be connected to the movable part on the formation equipment through a structural connection; when the movable part on the formation equipment moves, since the suction nozzle connecting component 2 and the structural connection component 3 are both arranged on the tool base 1, the movable part can drive the tool base 1 to move through the connection with the connecting part 31, and then the tool base 1 can drive the suction nozzle connecting component 2 thereon to move, so that the suction nozzle can be pulled out from the formation equipment through the movement of the suction nozzle connecting component 2.

[0053] Since the connecting part 31 in the structural connection assembly 3 of the present application is connected to the movable part on the chemical formation equipment by means of structural connection, compared with the related art, the present application does not need to be connected to the movable part on the chemical formation equipment by means of adsorption such as electromagnetic adsorption, and since the structural connection method is a connection between mechanical structures, the present application does not have high requirements on the material, manufacturing accuracy and manufacturing process of the movable part, that is, the present application can reduce the requirements on the material, manufacturing accuracy and manufacturing process of the movable part, which is conducive to reducing the manufacturing cost of the chemical formation equipment.

[0054] As for the movable parts, in this embodiment, the movable parts are movable frames that can move up and down on the formation equipment. When the movable frame moves downward, it can drive the tooling base 1 to move downward and drive the nozzle connecting assembly 2 to move downward, and then the nozzle connecting assembly 2 can pull the nozzle out of the formation equipment downward.

[0055] In other embodiments, the movable part may also be other movable structures on the formation equipment, and the movable direction of the movable part may not be the up and down direction, which is not specifically limited in the embodiments of the present application.

[0056] Regarding the nozzle connection assembly 2, in one embodiment, the nozzle connection assembly 2 includes a clamping claw for clamping the nozzle to achieve connection between the nozzle connection assembly 2 and the nozzle. The clamping claw not only facilitates the connection between the nozzle connection assembly 2 and the nozzle, but also ensures the reliability of the connection between the nozzle connection assembly 2 and the nozzle to a certain extent.

[0057] In another embodiment, the nozzle connection assembly 2 may also include an adhesive member for bonding the nozzle to achieve connection between the nozzle connection assembly 2 and the nozzle. The adhesive method is relatively simple, does not require complex mechanical structures and installation steps, and can quickly achieve connection between the nozzle and the nozzle connection assembly 2.

[0058] like Figure 2As shown, a nozzle storage box 4 is provided in the tooling base 1. The nozzle storage box 4 is used to store the nozzles removed from the formation equipment. Specifically, after the nozzle connecting assembly 2 removes the nozzle from the formation equipment, the nozzle enters the tooling base 1 and then enters the nozzle storage box 4. The nozzle storage box 4 can store the nozzles removed from the formation equipment in an orderly manner, preventing the nozzles from being scattered or placed in a disorderly manner, and facilitating subsequent sorting and management.

[0059] For the structural connection component 3, further, as Figure 3 As shown, a plurality of structural connection components 3 are arranged in an array.

[0060] With such an arrangement, on the one hand, multiple structural connection components 3 work together to share the load and stress during the working process, reduce the risk of failure of a single component leading to failure of the entire system, and can improve stability and reliability; on the other hand, the array setting helps to transfer the force and movement from the movable parts more evenly to the tooling base 1 and the suction nozzle connection component 2, avoiding damage or performance degradation caused by excessive local force or uneven movement; on the third hand, if one or several structural connection components 3 have problems, the other structural connection components 3 can still maintain the basic operation of the tooling to a certain extent, and it is also convenient to separately maintain or replace a single damaged structural connection component 3 without affecting the normal operation of the entire system.

[0061] Regarding the number of structural connection components 3, in the embodiment of the present application, there can be two, three, four or more structural connection components 3. The number of structural connection components 3 is flexible and is not specifically limited in the embodiment of the present application.

[0062] Of course, if the beneficial effects of providing multiple structural connection components 3 are not considered, only one structural connection component 3 may be provided. In this case, since the number of structural connection components 3 is small, it is not only convenient to assemble the nozzle extraction tooling, but also possible to reduce the manufacturing cost of the nozzle extraction tooling to a certain extent.

[0063] Regarding the array setting of multiple structural connection components 3, in the embodiment of the present application, the multiple structural connection components 3 can be arranged in an array manner such as a rectangle, a ring, etc. The array setting of multiple structural connection components 3 is relatively flexible, and the embodiment of the present application does not make any specific limitation on this.

[0064] For the connecting member 31, further, in a preferred embodiment, as Figure 4 As shown, the connecting member 31 is a claw, which is used to be clamped on the movable member so that the connecting member 31 and the movable member are connected through a structural connection.

[0065] The connecting member 31 is set as a claw. On the one hand, under normal working conditions, the claw can provide a more reliable connection and is not prone to accidental loosening. On the other hand, the claw has a simple structure and can achieve rapid connection and disconnection with the movable part, which is conducive to improving work efficiency.

[0066] In other embodiments, the connecting member 31 may also be a hook, a flange, etc. The structural setting of the connecting member 31 is relatively flexible. Specifically, it can be determined according to actual usage requirements. The embodiments of the present application do not make specific limitations on this.

[0067] like Figure 1 As shown, the tool base 1 is provided with an installation cavity 11, and the structural connection component 3 is provided in the installation cavity 11, as shown in FIG. Figure 3 As shown, the tool base 1 is provided with an extension hole 12, and the extension hole 12 allows the connecting member 31 to extend out of the tool base 1 to be connected with the movable member.

[0068] Such a setting, on the one hand, can effectively reduce the impact and interference of external factors on the operation of the structural connection component 3, ensuring its normal operation and protection from damage; on the other hand, it can make full use of the internal space of the tooling base 1, making the overall structure of the tooling more compact, which is conducive to reducing the space occupied by the tooling.

[0069] Furthermore, if Figure 4 and Figure 5 As shown, the structural connection assembly 3 further includes a driving structure 32 , which is used to drive the connection member 31 to move so that the connection member 31 extends out of the tooling base 1 through the extension hole 12 .

[0070] With such a setting, on the one hand, the automatic extension and retraction of the connecting member 31 can be achieved without manual operation, thereby improving work efficiency and operational convenience. At the same time, it can not only avoid the safety risks that may be brought about by direct manual operation, but also reduce the labor intensity of the operator; on the other hand, in conjunction with the corresponding control system, the activities of the connecting member 31 can be remotely controlled, which is convenient for operation in complex or inaccessible working environments.

[0071] Furthermore, in a preferred embodiment, Figure 4 and Figure 5 As shown, the driving structure 32 includes an electromagnet 321 and a piston rod 322. The piston rod 322 is transmission-connected to the connecting member 31. The electromagnet 321 is used to drive the piston rod 322 to move along its own axial direction through electromagnetic force, so that the piston rod 322 drives the connecting member 31 to move.

[0072] With such an arrangement, on the one hand, the electromagnetic force of the electromagnet 321 responds quickly, which can cause the piston rod 322 to move quickly, thereby quickly driving the connecting part 31 to move, which is conducive to achieving a quick connection between the connecting part 31 and the movable part, and thus is conducive to improving work efficiency; on the other hand, the electromagnet 321 only consumes energy when it needs to move, and consumes almost no electricity when it is not working, which has a good energy-saving effect.

[0073] In other embodiments, the driving structure 32 may also be any one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder, which is not specifically limited in the embodiments of the present application.

[0074] Furthermore, if Figure 6 As shown, a guide hole 3211 is provided on the electromagnet 321 , and the piston rod 322 is provided in the guide hole 3211 along its own axial direction.

[0075] With such a setting, on the one hand, the overall structure of the driving structure 32 can be made more compact, which is conducive to reducing the space occupied by the driving structure 32; on the other hand, the guide hole 3211 provides a clear linear motion track for the piston rod 322, ensuring that the piston rod 322 performs precise linear motion along its own axis, which can avoid the piston rod 322 from being offset, skewed, etc.; on the third hand, the guide hole 3211 limits the degree of freedom of the piston rod 322, making it more stable during movement, and reducing the vibration and shaking of the piston rod 322 caused by external interference or uneven internal force.

[0076] like Figure 1 and Figure 3 As shown, the tool base 1 includes a base plate 13 , the structural connection component 3 and the extension hole 12 are both arranged on the base plate 13 , and the axial direction of the piston rod 322 is parallel to the plate surface of the base plate 13 .

[0077] The axial direction of the piston rod 322 is set parallel to the plate surface of the base plate 13, so that the layout of the entire drive structure 32 in the tooling base 1 is more compact, which can effectively save space perpendicular to the plate surface of the base plate 13 and facilitate the arrangement of the drive structure 32 in the tooling base 1.

[0078] Furthermore, in a preferred embodiment, Figure 4 and Figure 6 As shown, the structural connection assembly 3 also includes a fixed seat 33 and a sliding member 34. The fixed seat 33 is arranged on the base plate 13. The sliding member 34 is slidably arranged on the fixed seat 33 along the axial direction of the piston rod 322, and the sliding member 34 is connected to the piston rod 322. A sliding groove 341 is provided on the sliding member 34, and the length direction of the sliding groove 341 extends along a direction different from the axial direction of the piston rod 322.

[0079] like Figure 4 and Figure 6 As shown, the connecting member 31 includes a first connecting arm 311, and the first connecting arm 311 is provided with a first hinge portion and a first insertion portion 3111. The first hinge portion and the first insertion portion 3111 are arranged at intervals along the length direction of the first connecting arm 311. The first hinge portion is hingedly connected to the fixed seat 33, and the first insertion portion 3111 can be movably inserted into the sliding groove 341 along the length direction of the sliding groove 341.

[0080] With this arrangement, when the piston rod 322 moves along its own axial direction, the piston rod 322 can drive the sliding member 34 to slide along the axial direction of the piston rod 322 on the fixing seat 33, thereby allowing the first insertion portion 3111 to move in the sliding groove 341 along the length direction of the sliding groove 341, thereby driving the first connecting arm 311 to swing around the hinge axis of the first hinge portion, thereby allowing the connecting member 31 to extend out of the tooling base 1 (through the extension hole 12) Figure 1 and Figure 7 shown).

[0081] When the piston rod 322 moves in the opposite direction along its own axial direction, the piston rod 322 can drive the sliding member 34 to slide in the opposite direction along the axial direction of the piston rod 322 on the fixing seat 33, thereby enabling the first insertion portion 3111 to move in the opposite direction along the length direction of the sliding groove 341 in the sliding groove 341, thereby driving the first connecting arm 311 to swing in the opposite direction around the hinge axis of the first hinge portion, thereby enabling the connecting member 31 to enter the tooling base 1 ( Figure 6 shown).

[0082] According to the above, on the one hand, through the sliding of the sliding member 34 and the movement of the first insertion part 3111 in the sliding groove 341, the linear motion of the piston rod 322 can be converted into a swing of a certain angle of the connecting member 31, so that when the axial direction of the piston rod 322 is parallel to the plate surface of the base plate 13, it is convenient for the driving structure 32 to drive the connecting member 31 to move, so that the connecting member 31 extends out of the tooling base 1 through the extension hole 12; on the other hand, through the sliding cooperation between the sliding member 34 and the fixed seat 33, the active cooperation between the first insertion part 3111 and the sliding groove 341, and the hinged cooperation between the first hinge part and the fixed seat 33, it helps to improve the stability of the connecting member 31 during movement, which is beneficial to reduce the jitter and deviation of the connecting member 31.

[0083] Regarding the first insertion portion 3111 , in one embodiment, the first insertion portion 3111 is a cam bearing.

[0084] The cam bearing can significantly reduce the friction coefficient of the first insertion portion 3111 when moving in the sliding groove 341, thereby helping to reduce energy loss and component wear caused by friction, and helping to extend the service life.

[0085] In other embodiments, the first insertion portion 3111 may also be a round rod or a rolling ball. The structural setting of the first insertion portion 3111 is relatively flexible. Specifically, it can be selected according to actual usage requirements. The embodiments of the present application do not make specific limitations on this.

[0086] For the first hinge part, in the embodiment of the present application, Figure 4 As shown, when the fixing seat 33 is provided with a rotating shaft 35, the first hinge portion is a through-hole for the rotating shaft 35 to pass through and rotatably cooperate with the rotating shaft 35. Alternatively, when the fixing seat 33 is provided with a hinge hole for hingedly cooperating with the first hinge portion, the first hinge portion can be a hinge shaft inserted into the hinge hole and rotatably cooperate with the hinge hole.

[0087] The structural setting of the first hinge part is relatively flexible. Specifically, it can be selected according to actual usage requirements. The embodiments of the present application do not make specific limitations on this.

[0088] For the connecting member 31, further, as Figure 5 As shown, the connecting member 31 further includes a second connecting arm 312 . The length directions of the second connecting arm 312 and the first connecting arm 311 extend in the same direction, and the sliding member 34 is located between the second connecting arm 312 and the first connecting arm 311 .

[0089] The second connecting arm 312 is provided with a second hinge portion, which is hingedly connected to the fixing seat 33; and / or, the second connecting arm 312 is provided with a second insertion portion, which is movably inserted into the sliding groove 341 along the length direction of the sliding groove 341.

[0090] With such an arrangement, on the one hand, the presence of the second connecting arm 312 increases the contact area and contact points between the connecting member 31 and the sliding member 34, making the connecting member 31 more stable during movement and reducing the shaking and deviation of the connecting member 31; on the other hand, the sliding member 34 is located between the two connecting arms, and during movement, the force can be more evenly distributed on the first connecting arm 311 and the second connecting arm 312, reducing the force concentration of a single connecting arm, thereby helping to reduce the fatigue and damage risk of the connecting member 31.

[0091] As for the second hinge part and the second insertion part, in the embodiment of the present application, the second hinge part is exactly the same as the first hinge part, and the second insertion part is exactly the same as the first insertion part, and the embodiment of the present application will not elaborate on this.

[0092] Furthermore, if Figure 5 As shown, the first connecting arm 311 is a long arm and the second connecting arm 312 is a short arm. Figure 5 and Figure 6As shown, the connecting member 31 further includes a connecting portion 313 connected to the second connecting arm 312 and the first connecting arm 311 at the same end. The connecting portion 313 is used to connect to the above-mentioned movable part on the formation equipment through a structural connection.

[0093] like Figure 5 and Figure 6 As shown, the first insertion portion 3111 is arranged at the end of the first connecting arm 311 away from the connecting portion 313, the first hinged portion is arranged between the connecting portion 313 and the first insertion portion 3111, and the second hinged portion is arranged on the second connecting arm 312; or, the first hinged portion is arranged at the end of the first connecting arm 311 away from the connecting portion 313, the first insertion portion 3111 is arranged between the connecting portion 313 and the first hinged portion, and the second insertion portion is arranged on the second connecting arm 312.

[0094] With such a setting, on the one hand, the combination of the long arm and the short arm can form a more stable triangular or trapezoidal structure, which is beneficial to improving the overall stability and deformation resistance of the connecting member 31; on the other hand, while meeting functional requirements, it can reduce the use of materials and thus reduce manufacturing costs.

[0095] In addition, in the embodiment of the present application, since the first insertion portion 3111 is a cam bearing, the second connecting arm 312 is set to a short arm, which can provide an installation space for installing the cam bearing, which is conducive to facilitating the installation of the cam bearing.

[0096] In a preferred embodiment, Figure 5 and Figure 6 As shown, the first insertion portion 3111 is provided at one end of the first connecting arm 311 away from the connecting portion 313 , the first hinge portion is provided between the connecting portion 313 and the first insertion portion 3111 , and the second connecting arm 312 is provided with a second hinge portion.

[0097] The first insertion portion 3111 is arranged at the distal end of the first connecting arm 311 so that the connecting member 31 can obtain a larger travel range when moving.

[0098] The driving structure 32 is used to drive the connecting member 31 to swing around the hinge axis of the first hinge portion so that the connecting member 31 extends out of the tool base through the extension hole 12. Figure 4 and Figure 6 As shown, a reset elastic member 36 is provided between the fixed seat 33 and the piston rod 322 or between the fixed seat 33 and the sliding member 34. The reset elastic member 36 is used to drive the connecting member 31 to swing in the opposite direction through the elastic force generated by elastic deformation, so that the connecting member 31 enters the tooling base 1 through the extension hole 12.

[0099] With such a configuration, on the one hand, the reset elastic member 36 can automatically pull the connecting member 31 back to its initial position after the driving action of the driving structure 32 ends, thereby achieving fast and accurate reset and improving work efficiency; on the other hand, the elastic force of the reset elastic member 36 is utilized to achieve reset, without the need for additional driving energy, thereby reducing the energy consumption of the entire tooling; on the other hand, during the reverse swinging of the connecting member 31, the buffering effect of the reset elastic member 36 can reduce the impact force, thereby protecting components such as the driving structure 32, the sliding member 34 and the fixing seat 33 and extending their service life.

[0100] Regarding the reset elastic member 36 , in the embodiment of the present application, the reset elastic member 36 may be a compression spring, a tension spring, or an elastic rubber ring, etc. The type of the reset elastic member 36 can be selected flexibly, and the embodiment of the present application does not make any specific limitation on this.

[0101] Furthermore, if Figure 4 and Figure 6 As shown, the reset elastic member 36 is arranged on one side of the sliding member 34 in the axial direction of the piston rod 322, and a limiting member 37 is arranged between the fixed seat 33 and the sliding member 34. The limiting member 37 is arranged on the side of the sliding member 34 away from the reset elastic member 36 in the axial direction of the piston rod 322.

[0102] With such arrangement, when the reset elastic member 36 drives the sliding member 34 to reset in the reverse direction, the limiting member 37 limits the sliding member 34, thereby avoiding collision between the sliding member 34 and the fixing seat 33, thereby helping to avoid damage to both the sliding member 34 and the fixing seat 33.

[0103] In addition, if Figure 1 、 Figure 2 and Figure 3 As shown, a power supply connector 5 is also provided on the tooling base 1, and the power supply connector 5 is used to connect with the corresponding connector on the formation equipment to supply power to the entire suction nozzle tooling, and when the power supply connector 5 is connected with the corresponding connector on the formation equipment, the drive structure 32 is energized, and when the power supply connector 5 is disconnected from the corresponding connector on the formation equipment, the drive structure 32 is de-energized.

[0104] With such an arrangement, on the one hand, the automatic on and off of the power supply of the driving structure 32 is realized without the need for additional manual operation, thereby improving the degree of automation and efficiency of the work; on the other hand, the driving structure 32 is energized only when the power supply connector 5 is docked with the connector on the formation equipment, thereby avoiding energy waste when work is not needed, and also reducing circuit failures and safety hazards that may be caused by long-term power supply; on the third hand, the suction nozzle extraction tooling does not require additional configuration of a special power supply, which is conducive to reducing the manufacturing cost of the suction nozzle extraction tooling.

[0105] Regarding the structural connection component 3, in the embodiment of the present application, a working principle of the structural connection component 3 is as follows:

[0106] like Figure 7 As shown, when the driving structure 32 is energized, under the electromagnetic force of the electromagnet 321, the piston rod 322 moves in the positive direction of its own axis (as shown in FIG. Figure 7 The X1 direction in the figure), and the positive movement of the piston rod 322 will drive the sliding member 34 to slide in the positive direction along the axial direction of the piston rod 322, and compress the reset elastic member 36. At the same time, the positive sliding of the sliding member 34 will cause the first insertion portion 3111 to move in the sliding groove 341 along the length direction of the sliding groove 341, thereby driving the connecting member 31 to swing in the counterclockwise direction around the hinge axis of the first hinge part, and then the connecting member 31 can be extended out of the tooling base 1 through the extension hole 12.

[0107] like Figure 6 As shown, when the driving structure 32 is powered off, the piston rod 322 moves in the opposite direction of its own axis (as shown in FIG. Figure 6 The X2 direction in the figure), and the reverse movement of the piston rod 322 will drive the sliding member 34 to slide in the reverse direction along the axial direction of the piston rod 322. At the same time, the reverse sliding of the sliding member 34 will cause the first insertion portion 3111 to move in the reverse direction along the length direction of the sliding groove 341 in the sliding groove 341, thereby driving the connecting member 31 to swing in the clockwise direction around the hinge axis of the first hinge part, and then the connecting member 31 can enter the tooling base 1 through the extension hole 12.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
