Unless otherwise specified, "several" means two or more.

[0073] More detailed explanations of the technical solutions of this application will be given below, with reference to the specific embodiments and the attached figures.

[0074] With reference to [Fig. 1], [Fig. 2] and [Fig. 3], a nozzle insertion and extraction device 100 comprises: a transport positioning mechanism 1, a disassembly mechanism 2 and a nozzle insertion-extraction mechanism 3, wherein the transport positioning mechanism 1 is configured to transport a retaining tray A2 provided with a negative pressure assembly Al to a disassembly station 3, the disassembly mechanism 2 is configured to detach the negative pressure assembly Al disposed on the disassembly station from the retaining tray A2, so that the negative pressure assembly Al and the retaining tray A2 are detached from each other, the transport positioning mechanism 1 is further configured to move one of the negative pressure assembly Al and the retaining tray A2 away from each other,so that a worn nozzle B1 of the negative pressure assembly Al no longer presses against a battery on the retaining plate A2, the nozzle insertion-extraction mechanism 3 is configured to remove the worn nozzle B1 from the negative pressure assembly Al and to insert a new nozzle B2 into the negative pressure assembly Al.

[0075] According to the present embodiment, when a leakage condition is detected in the worn nozzle B1 of the negative pressure assembly Al on the retaining tray A2 and the nozzle needs to be replaced, first, the retaining tray A2 equipped with the negative pressure assembly Al is configured to be transported to the disassembly station by the transport positioning mechanism 1; once the retaining tray A2 equipped with the negative pressure assembly Al has arrived at the disassembly station, the negative pressure assembly Al disposed at the disassembly station is configured to be detached from the retaining tray A2 by the disassembly mechanism 2, so that the negative pressure assembly Al and the retaining tray A2 are detached from each other; then, one of the negative pressure assembly Al and the retaining tray A2 is configured to move away from the other by the transport positioning mechanism 1.so that the worn nozzle B1 on the negative pressure assembly Al no longer presses against the battery on the retaining plate A2, the worn nozzle B1 on the negative pressure assembly Al is protected against interference from the battery, finally, the worn nozzle B1 on the negative pressure assembly Al is configured to be removed by the nozzle insertion-extraction mechanism 3, and a new nozzle B2 is configured to be inserted into the negative pressure assembly Al by the nozzle insertion-extraction mechanism 3, thus, the nozzle replacement objective is achieved.

[0076] It can be seen that during nozzle replacement, the nozzle replacement objective can be achieved automatically thanks to the coordination of the transport positioning mechanism 1, the disassembly mechanism 2 and the nozzle insertion-extraction mechanism 3, without any personal intervention in the entire process, therefore, on the one hand, labor intensity is reduced, and on the other hand, replacement efficiency is improved.

[0077] It should be noted that the number of disassembly mechanisms 2 mentioned above is configured to be either one or four, depending on the specific mounting situation of the negative pressure assembly Al on the retaining plate A2. For example, assuming that the negative pressure assembly Al is removably connected to the retaining plate A2 by one linking structure, then the number of disassembly mechanisms 2 is configured to be one; assuming that the negative pressure assembly Al is removably connected to the retaining plate A2 by four linking structures, then the number of disassembly mechanisms 2 is configured to be four; the four disassembly mechanisms 2 are in one-to-one correspondence with the four linking structures, thus the objective of detaching the negative pressure assembly Al from the retaining plate A2 can be achieved.

[0078] In which, the structure of the disassembly mechanism 2 mentioned above is configured to be specific to the structure of the linking structure, assuming that the linking structure is a spring clamp, then the disassembly structure may include a disassembly cylinder, by causing a piston rod of the disassembly cylinder to push a gripping end of the spring clamp, a clamping orifice of the spring clamp is configured to be open, thus the objective of detaching the negative pressure assembly Al disposed on the disassembly station of the retaining tray A2 can be achieved.

[0079] Obviously, based on different linking structures, the disassembly mechanism 2 can also have other possible structures, and the disassembly mechanism 2 is not limited in this embodiment.

[0080] In which the above description in which the transport positioning mechanism 1 is further configured to move one of the negative pressure assembly Al and the retaining plate A2 away from the other refers to that: in a first case, the retaining plate A2 remains stationary, the transport positioning mechanism 1 moves the negative pressure assembly Al away from the retaining plate A2, in a second case, the negative pressure assembly Al remains stationary, the transport positioning mechanism 1 moves the retaining plate A2 away from the negative pressure assembly Al, regardless of the case mentioned above, provided that the worn nozzle B1 on the negative pressure assembly Al is configured to no longer press against the battery on the retaining plate A2, which is not limited in this embodiment.

[0081] It should be noted that the new B2 nozzle mentioned above is configured to be understood in a broad sense; the new B2 nozzle does not specifically referring to a brand new nozzle, any nozzle that works well after being cleaned and restored can be considered a new B2 nozzle, and the worn B1 nozzle mentioned above refers to a nozzle to be replaced.

[0082] When the negative pressure assembly Al remains stationary, the transport positioning mechanism 1 moves the retaining plate A2 away from the negative pressure assembly Al, in order to prevent the negative pressure assembly Al from falling off the retaining plate A2 during the transport process. According to some embodiments, the disassembly mechanism 2 is further configured to hold the negative pressure assembly Al detached from the retaining plate A2 within the disassembly mechanism 2. Thus, the disassembly mechanism 2 is configured to serve to clamp the negative pressure assembly Al. Therefore, the circumstance where the negative pressure assembly Al falls off the retaining plate A2 can be avoided when the transport positioning mechanism 1 moves the retaining plate A2 away from the negative pressure assembly Al.

[0083] It should be noted that the above description in which the disassembly mechanism 2 is further configured to keep the negative pressure assembly Al detached from the retaining plate A2 in the disassembly mechanism 2 refers to the fact that: the disassembly mechanism 2 is configured to keep the negative pressure assembly Al on the disassembly mechanism 2 or release the negative pressure assembly Al from a bond with the disassembly mechanism 2 depending on the actual circumstances.

[0084] In particular, once the negative pressure assembly Al is detached from the retaining plate A2, so that the negative pressure assembly Al remains stationary in the process of moving the retaining plate A2 away from the negative pressure assembly Al, the negative pressure assembly Al can be held in the disassembly mechanism 2.

[0085] Once the disassembly mechanism 2 has reassembled the negative pressure assembly Al onto the retaining plate A2, in order to ensure that the assembly formed by the negative pressure assembly Al and the retaining plate A2 moves away from the disassembly mechanism 2, the negative pressure assembly Al can be released from the connection with the disassembly mechanism 2, which ensures that the assembly formed by the negative pressure assembly Al and the retaining plate A2 can move away from the disassembly mechanism 2.

[0086] Several embodiments are provided for the transport positioning mechanism A1 mentioned above. In one of the possible embodiments, with reference to [Fig. 2] and [Fig. 4], the transport positioning mechanism A1 comprises: a transport assembly 11 and a lifting positioning assembly 12, in which the transport assembly 11 is configured to transport the platform the retaining tray A2 equipped with the negative pressure assembly Al to a tray loading station, the lifting positioning assembly 12 is configured to be disposed under the tray loading station, the lifting positioning assembly 12 is configured to lift the retaining tray A2 equipped with the negative pressure assembly Al from the tray loading station to the disassembly station, and the lifting positioning assembly 12 is further configured to drive the retaining tray A2 down to the tray loading station, so that the retaining tray A2 moves away from the negative pressure assembly Al.

[0087] According to this embodiment, when the retaining tray A2 equipped with the negative pressure assembly Al is to be transported to the disassembly station, firstly, the retaining tray A2 equipped with the negative pressure assembly Al can be transported to the tray loading station by the transport assembly 11, once the retaining tray A2 equipped with the negative pressure assembly Al has arrived at the tray loading station, the lifting positioning assembly 12 is configured to lift the retaining tray A2 from the bottom, so that the retaining tray A2 equipped with the negative pressure assembly Al is lifted from the tray loading station to the disassembly station, thus, the objective of transporting the retaining tray A2 equipped with the negative pressure assembly Al to the disassembly station is achieved.

[0088] Once the retaining tray A2 equipped with the negative pressure assembly Al is transported to the disassembly station and the negative pressure assembly Al disposed on the disassembly station is detached from the retaining tray A2 by the disassembly mechanism 2, the negative pressure assembly Al detached from the retaining tray A2 can be held in the disassembly mechanism 2 by the disassembly mechanism 2, then, the lifting positioning assembly 12 is configured to drive the retaining tray A2 down to the tray loading station, thus, the objective of moving the retaining tray A2 away from the negative pressure assembly Al is achieved.

[0089] It can be seen that the lifting positioning assembly 12 plays a role, on the one hand, in lifting the retaining platform A2 equipped with the negative pressure assembly Al from the platform loading station to the disassembly station, and on the other hand, the lifting positioning assembly 12 plays a role in driving the retaining platform A2 downwards, in order to achieve the objective of moving the retaining platform A2 away from the negative pressure assembly Al. The lifting positioning assembly 12 has a multi-function, and gravity is also used to provide the lowering force for the retaining platform A2. which allows on the one hand to simplify the structure of the transport positioning mechanism 1, and on the other hand to reduce the cost of labor.

[0090] The above description in which the transport assembly 11 is configured to be any of a roller transport structure, a belt transport structure or a chain transport structure, as long as the objective of transporting the retaining tray A2 equipped with the negative pressure assembly Al to the tray loading station can be achieved, the transport assembly 11 is not limited in this embodiment.

[0091] Several embodiments are provided for the lifting positioning assembly 12 mentioned above. In one of the possible embodiments, referring to [Fig.2] and [Fig.4], the lifting positioning assembly 12 comprises a first mounting component 123, a lifting drive component 121, and a lifting component 122. In this embodiment, the lifting drive component 121 is disposed on the first mounting component 123, the lifting component 122 is configured to slide on the first mounting component 123, a positioning component 1221 corresponding to the retaining plate A2 is disposed on the lifting component 122, and the lifting drive component 121 is configured to drive the lifting component 122 upwards a first distance.so that the retaining platform A2 equipped with the negative pressure assembly Al is lifted from the platform loading station to the disassembly station, and the lifting drive component 121 is further configured to drive the lifting component 122 downwards, so that the retaining platform A2 is driven downwards to the platform loading station synchronously.

[0092] Because a positioning component 1221 corresponding to the retaining plate A2 is disposed on the lifting component 122, the position of the retaining plate A2 on the lifting component 122 is relatively precise under the action of the positioning component 1221, therefore, when the retaining plate A2 provided with the negative pressure assembly Al is lifted a first distance by the lifting component 122 to go up from the plate loading station to the disassembly station, the position of the negative pressure assembly Al on the disassembly station is relatively precise, which allows the disassembly mechanism 2 to detach the negative pressure assembly Al from the retaining plate A2, and prevents the negative pressure assembly Al from being detached from the retaining plate A2 due to misalignment between the disassembly mechanism 2 and the negative pressure assembly Al.

[0093] Wherein, the lifting drive component 121 mentioned above is configured to be an air cylinder, an electric cylinder or others, and the The lifting drive component 121 is not limited in this embodiment. The lifting component 122 mentioned above can be a plate-shaped structure or any other possible structure, and the lifting component 122 is also not limited in this embodiment.

[0094] The positioning component 1221 mentioned above can be a positioning pin, a positioning block or others, as long as the positioning component 1221 can be used to position the retaining plate A2, and the positioning component 1221 is not limited in this embodiment.

[0095] Several ways are provided for the lifting component 122 mentioned above which is slidably arranged on the first mounting component 123, for example, the lifting component 122 is configured to be slidably arranged on the first mounting component 123 using a guide column, obviously, the lifting component 122 is configured to be slidably arranged on the first mounting component 123 in other ways, which is not limited in this embodiment.

[0096] In addition, the lifting component 122 and the first mounting component 123 mentioned above can be a plate-shaped structure or any other possible structure, which is not limited in this embodiment.

[0097] According to some embodiments, with reference to [Fig.1] and [Fig.5], the nozzle insertion and extraction device 100 further comprises: a buffer assembly 4, the buffer assembly 4 is attached to the transport assembly 11, the transport assembly 11 is configured to transport the retaining tray A2 lowered to the tray loading station to the buffer assembly 4, so that the retaining tray A2 is separated from the lifting component 122, and the buffer assembly 4 is configured to buffer the retaining tray A2.

[0098] The retaining platform A2 lowered to the platform loading station can be buffered in the buffer assembly 4 in time by providing the buffer assembly 4, and the retaining platform A2 is separated from the lifting component 122, in this way, on the one hand, no obstruction of the retaining platform A2 exists between the lifting component 122 and the negative pressure assembly Al, thus providing an action space allowing the lifting component 122 to perform other subsequent actions, on the other hand, the buffer assembly 4 is further configured to provide a special storage space for the retaining platform A2, in order to avoid or reduce the possibility of mutual interference between the retaining platform A2 and other structures.

[0099] Wherein, with reference to [Fig. 4], the buffer assembly mentioned above 4 is configured to be any one of a roller conveyor structure, a belt conveyor structure, or a chain conveyor structure. In particular, when the buffer assembly 4 is the roller conveyor structure, the assembly Buffer 4 is configured to include several rollers 42, the several rollers 42 are configured to be arranged in a rotating manner and in rows, so that when the roller 42 rotates, the objective of buffering the retaining tray A2 in the buffer assembly 4 in a timely manner can be achieved.

[0100] Due to the mature and stable operation of the roller conveying structure, belt conveying structure or chain conveying structure, the stability of the operation of the buffer assembly 4 can be guaranteed.

[0101] When the buffer assembly 4 is configured to be any one of the roller conveying structure, the belt conveying structure, or the chain conveying structure, the inlet end of the buffer assembly 4 is attached to the outlet end of the conveying assembly 11, and both the buffer assembly 4 and the conveying assembly 11 are configured to perform transport in forward and backward directions. Thus, when the retaining tray A2 on the tray loading station is to be buffered into the buffer assembly 4, first, the conveying assembly 11 is configured to transport the retaining tray A2 in a direction close to the inlet end of the buffer assembly 4, so that the retaining tray A2 can arrive at the buffer assembly 4 by passing through the outlet end of the conveying assembly 11 and the inlet end of the buffer assembly 4 sequentially. Then,Buffer assembly 4 is configured to continuously transport the retaining plate A2 in the direction away from transport assembly 11, so that the retaining plate A2 is completely separated from transport assembly 11.

[0102] In order to prevent the retaining plate A2 from falling from the buffer assembly 4 due to an excessively long transport path in the transport process of the buffer assembly 4 which transports the retaining plate A2 in the direction away from the transport assembly 11, according to certain embodiments, with reference to [Fig.5], a retaining plate blocking component 41 is disposed on the buffer assembly 4, the retaining plate blocking component 41 is disposed on a transport path of the retaining plate A2 and configured to prevent the buffer assembly 4 from transporting the retaining plate A2 in the direction away from the transport assembly 11.

[0103] Thus, by providing the retaining tray blocking component 41, the occurrence of the circumstance of the fall from the buffer assembly 4 due to an excessive transport path of the buffer assembly 4 which carries out a transport in the direction away from the transport assembly 11, is avoided.

[0104] The retaining plate locking component 41 mentioned above is configured to be a stop block, a stop plate or others, which is not limited in this embodiment.

[0105] In order to ensure stable transport of the retaining plate A2 when the retaining plate A2 is transported to the buffer assembly 4 by the transport assembly 11, the transport speed of the transport assembly 11 and the transport speed of the buffer assembly 4 are configured to be identical, thus the process of transporting the retaining plate A2 from the transport assembly 11 to the buffer assembly 4 is very stable.

[0106] Because the buffer assembly 4 and the transport assembly 11 are both configured to carry out transport in forward and backward directions, the retaining tray A2 is configured to be brought back to the transport assembly 11, the function being very versatile.

[0107] Once the retaining plate A2 is buffered in the buffer assembly 4, the lifting drive component 121 is further configured to drive the lifting component 122 to rise a second distance to a leak detection station, so that the worn nozzle B1 on the negative pressure assembly Al rests against the lifting component 122, the second distance being different from the first distance.

[0108] When the lifting drive element 121 causes the lifting component 122 to rise a second distance to the leak detection station, the worn nozzle B1 of the negative pressure assembly Al presses against the lifting component 122 precisely, thus the lifting component 122 is configured to serve to close the opening of the worn nozzle Bl, providing a basis for performing leak detection on the worn nozzle Bl.

[0109] It can be seen that the lifting component 122 plays a role, on the one hand, in lifting the retaining plate A2, equipped with the negative pressure assembly Al, from the plate loading station to the disassembly station mentioned above, and in causing the retaining plate A2 to descend in order to move the retaining plate A2 away from the negative pressure assembly Al. On the other hand, the lifting component 122 plays a role in sealing the opening of the worn nozzle Bl by raising the lifting component 122 a second distance until the lifting component 122 rests against the worn nozzle Bl. The design of the structure is very ingenious; several functions can be performed by means of a lifting component 122. Consequently, the cost of the nozzle insertion and extraction device 100 is reduced while the structure of the nozzle insertion and extraction device 100 is simplified.

[0110] When the lifting component 122 is mounted, in order to ensure that the retaining tray A2 equipped with the negative pressure assembly Al is configured to be lifted from the tray loading station to the disassembly station and to be mounted from the second distance to the leak detection station accurately, According to certain embodiments, with reference to [Fig.2], the nozzle insertion and extraction device 100 further comprises: a passage limitation mechanism 5, the passage limitation mechanism 5 is configured to limit the lifting component 122 from rising from the first or second distance, so that the lifting component 122 rises to the disassembly station or the leak detection station.

[0111] By providing the passage limitation mechanism 5, according to one of the possible embodiments, as required, the passage limitation mechanism 5 is configured to move the limitation component to the height where the disassembly station is located or to the height where the leak detection station is located in front, so that when the lifting component 122 is raised respectively from the first distance and the second distance, the lifting component 122 is configured to be engaged respectively with the preset limitation component, thus ensuring the accuracy of the ascent of the lifting component 122 to the disassembly station or to the leak detection station.

[0112] Obviously, the passage limitation mechanism 5 is further configured to limit the lifting component 122 from rising from the first distance or the second distance by other embodiments, which is not described here in this embodiment.

[0113] According to some embodiments, with reference to [Fig. 1], the nozzle insertion and extraction device 100 further comprises: a leak detection assembly 6, the negative pressure assembly B1 comprising several columns of worn nozzles Bl, the leak detection assembly 6 is configured to detect the existence of a possible leak in one of the columns of worn nozzles Bl, and the nozzle insertion-extraction mechanism 3 is configured to remove the column of worn nozzles Bl where the leak exists.

[0114] Because the leak detection assembly 6 is configured to detect a column of worn nozzles B1 where the leaking nozzle exists, therefore the nozzle insertion-extraction mechanism 3 is configured to remove only the column of worn nozzles Bl where the leaking nozzle exists, the column of worn nozzles Bl where the leaking nozzle does not exist need not be removed, i.e. it is not necessary to remove all the worn nozzles Bl, therefore the cost of the nozzle can be reduced, thus avoiding nozzle waste.

[0115] According to certain embodiments, with reference to [Fig. 6], the leak detection assembly 6 comprises a first seat 61, a leak drive component 62, a second mounting component 63, and several attachment assemblies 64. The several attachment assemblies 64 are all arranged on the second mounting component 63 and are in one-to-one correspondence with the several columns For worn nozzles Bl, each of the attachment assemblies 64 corresponds to a convergence pipe of each column of worn nozzles Bl. The second mounting component 63 is slidably arranged on the first seat 61. The leak drive component 62 is configured to drive the second mounting component 63 to move the several attachment assemblies 64 in a direction close to the negative pressure assembly Al, so that the attachment assembly 64 is attached to the corresponding convergence pipe to detect a possible leak in one of the columns of worn nozzles Bl. Thus, the objective of detecting a possible leak in one of the columns of worn nozzles Bl can be achieved.

[0116] By arranging all the attachment assemblies 64 on the second mounting component 63, when the leak detection component 62 causes the second mounting component 63 to slide, the multiple attachment assemblies 64 are configured to be attached simultaneously to the corresponding convergence pipe, thus improving the efficiency of the attachment.

[0117] Obviously, the leak detection assembly 6 is further configured to be other possible structures, and in order to improve the user experience, the leak detection assembly 6 is further configured to send the detection result to a display screen of the nozzle insertion and extraction device 100, or, the leak detection assembly 6 is configured to broadcast by voice, which is not limited in this embodiment.

[0118] Wherein, the leak detection component 62 mentioned above is configured to be an air cylinder, an electric cylinder or others, which is not limited in this embodiment.

[0119] According to some embodiments, with reference to [Fig.1], [Fig.7] to [Fig.16], the nozzle insertion-extraction mechanism 3 comprises: a three-axis movement module 31 and an insertion-extraction tool 32, wherein the insertion-extraction tool 32 is disposed on the three-axis movement module 31, the three-axis movement module 31 is configured to drive the nozzle insertion-extraction tool 32 to move towards the negative pressure assembly Al, and the nozzle insertion-extraction tool 32 is configured to remove the worn nozzle Bl from the negative pressure assembly Al and insert the new nozzle B2 into the negative pressure assembly Al.

[0120] Once the new nozzle B2 is inserted into the negative pressure assembly Al, the negative pressure assembly Al is configured to be reassembled onto the retaining plate A2 through the coordination of the disassembly mechanism 2 and the transport positioning mechanism 1. This specific process is the opposite of the process of detaching the negative pressure assembly Al from the retaining plate A2. refer to the description in the embodiment mentioned above for the specific process of detaching the negative pressure assembly Al from the retaining plate A2, which will not be repeated in this embodiment.

[0121] Because the three-axis motion module 31 is configured to be adjusted to the multi-freedom position, the three-axis motion module 31 is configured to perform omnidirectional fixed-point coverage on the negative pressure assembly Al, therefore, the three-axis motion module 31 is configured to drive the insertion-extraction tool 32 to move to any position on the negative pressure assembly Al, thus the objective of inserting and extracting any nozzle can be achieved.

[0122] In particular, the three-axis motion module 31 mentioned above is configured to include an X axis, a Y axis and a Z axis, each of the axes is configured to be implemented through a screw or other structure, which is not limited in this embodiment.

[0123] According to certain embodiments, with reference to [Fig.8] to [Fig. 11] and [Fig. 13] to [Fig.

[16] , the insertion-extraction tool 32 comprises: a base 321, an extraction head 322, and an insertion head 323, wherein the base 321 is disposed on a three-axis motion module 31, the extraction head 322 is disposed on the base 321, the three-axis motion module 31 is configured to drive the extraction head 322 to move towards the negative pressure assembly Al, the extraction head 322 is configured to remove the worn nozzle B1 from the negative pressure assembly Al, so that the negative pressure assembly Al is exposed to an insertion-extraction orifice Al 1, the insertion head 323 is disposed on the base 321, the insertion head 323 is configured to place the new nozzle B2, the three-axis motion module 31 is further configured to drive the insertion head 323 to Move to the negative pressure assembly Al to insert the new nozzle B2 into the insertion-extraction orifice Ail.

[0124] Because the extraction head 322 and the insertion head 323 are both arranged on the base 321, i.e., the extraction head 322 and the insertion head 323 are both integrated for arrangement on the base 321, an insertion-extraction tool 32 is formed for the function of removing the worn nozzle B1 and inserting the new nozzle B2. Consequently, when replacing the nozzle, the same insertion-extraction tool 32 can be driven by the same three-axis motion module 31. It is not necessary to design a special tool for removing the worn nozzle B1 and a tool for inserting the new nozzle B2, respectively, and it is not necessary to set up two different drives to drive the two tools to move respectively. That is, two tools can be replaced by a single insertion-extraction tool 32, reducing thus the cost. On the other hand, this allows to avoid the occurrence of mutual interference between the two different drives during the movement of the two tools. Furthermore, this also helps to avoid or reduce the occurrence of mutual interference between the nozzle extraction tool, the nozzle insertion tool, and the worn nozzle B1 on the negative pressure assembly during movement, caused by the limited space available for movement.

[0125] According to some embodiments, with reference to [Fig.1] and [Fig.17], the nozzle insertion and extraction device 100 further comprises: a nozzle supply mechanism 7, the nozzle supply mechanism 7 is configured to supply the nozzle insertion-extraction mechanism 3 with a new nozzle B2, and the nozzle insertion-extraction mechanism 3 is configured to transport the new nozzle B2 to the negative pressure assembly Al.

[0126] By providing the nozzle feeding mechanism 7, automatic feeding of new nozzle B2 can be achieved, the level of automation of the nozzle insertion and extraction device 100 is higher, and the labor intensity of personnel is further reduced.

[0127] Several embodiments are provided for the nozzle feeding mechanism 7 mentioned above; in one of the possible embodiments, the nozzle feeding mechanism 7 comprises: a vibrating plate 71, a nozzle transport assembly 72 and a nozzle blocking component 73, wherein the vibrating plate 71 is configured to supply the new nozzle B2 to the discharge outlet of the vibrating plate; the nozzle blocking component 73 is disposed between the discharge outlet of the vibrating plate and the nozzle transport assembly 72; the nozzle blocking component 73 is configured to block the new nozzle B2 at the discharge outlet of the vibrating plate or to allow the new nozzle B2 to move through the discharge outlet of the vibrating plate to the nozzle transport assembly 72.and the nozzle transport assembly 72 is configured to transport the new nozzle B2 to the nozzle insertion-extraction mechanism 3.

[0128] Because the feeding technology of the vibrating plate 71 is mature and can operate continuously, the feeding efficiency of the nozzle feeding mechanism 7 can be increased.

[0129] By providing the nozzle blocking component 73 between the discharge outlet of the vibrating plate and the nozzle transport assembly 72, the nozzle blocking component 73 is configured to allow the new nozzle B2 to move through the discharge outlet of the vibrating plate to the nozzle transport assembly 72 when the nozzle transport assembly 72 needs to be supplied with a new nozzle, thus facilitating the nozzle transport assembly 72 from transporting the new nozzle B2 to the nozzle insertion-extraction mechanism 3, and when the transport assembly The nozzle 72 must not be fed with new nozzle B2, the nozzle blocking component 73 is configured to block the new nozzle B2 at the discharge outlet of the vibrating plate, thus preventing the occurrence of the circumstance where the new nozzle B2 flows continuously towards the nozzle transport assembly 72, such circumstance causing the nozzle transport assembly 72 not to be able to transport the nozzle in time.

[0130] Wherein the nozzle transport assembly 72 mentioned above is configured to be a transporting robot arm, a gripper or others, which is not limited in this embodiment.

[0131] When the nozzle transport assembly 72 includes a robotic transport arm, the nozzle transport assembly 72 is configured to further include a temporary nozzle storage position, the nozzle blocking component 73 is configured to allow the new nozzle B2 to move through the discharge outlet of the vibrating plate to the temporary nozzle storage position, the robotic transport arm is configured to transport the new nozzle B2 from the temporary nozzle storage position to the nozzle insertion-extraction mechanism 3.

[0132] By providing the temporary nozzle storage position, because the temporary nozzle storage position is configured to provide a special position for the temporary storage of the new nozzle B2, therefore, when transporting the new nozzle B2 using the transport robot arm, the transport robot arm is configured to ensure a gripping of the new nozzle B2 by ensuring the transport robot arm moves to the temporary nozzle storage position, therefore, on the one hand, the reliability of the transport robot arm is guaranteed, and the transport efficiency is improved, on the other hand, the operating process of the transport robot arm is simplified, and the complexity of the transport robot arm is reduced.

[0133] The nozzle blocking component 73 mentioned above may be an air cylinder or others, and the nozzle blocking component 73 is not limited in this embodiment.

[0134] According to some embodiments, with reference to [Fig. 16], the nozzle feeding mechanism 7 further comprises: a waste material recycling assembly 74, and the nozzle insertion-extraction mechanism 3 is further configured to place the waste nozzle B1 into the waste material recycling assembly 74.

[0135] By providing the waste material recycling assembly 74, the waste nozzle B1 on the nozzle insertion-extraction mechanism 3 is configured to be placed in the waste material recycling assembly 74, thus facilitating the storage of the waste nozzle Bl.

[0136] Wherein, the waste material recycling assembly 74 mentioned above is configured to be a material recycling box, a material recycling bag or others, which is not limited in this embodiment.

[0137] According to some embodiments, the nozzle insertion and extraction device 100 is configured to further include a shell, an electrical control box and others, the electrical control box and each of the above-mentioned mechanisms are all arranged in the shell, thus, on the one hand, the nozzle insertion and extraction device 100 has a relative aesthetic appeal, on the other hand, the operating environment of each of the above-mentioned mechanisms is safer.

[0138] The negative pressure assembly is equipment used in a training device to provide negative pressure to the internal cavity of the battery, in order to perform a training operation on the battery. In order to improve the efficiency of the training, the number of negative pressure assemblies is generally defined as a plural number, and the several negative pressure assemblies are arranged in rows and columns on the tray. The several negative pressure assemblies arranged in rows and columns correspond uniquely to the batteries arranged in rows and columns. The nozzle of each negative pressure assembly is configured to be attached to a liquid injection port of the corresponding battery, so that the nozzle is configured to communicate with the internal cavity of the corresponding battery via the liquid injection port.By connecting the corresponding battery's internal cavity via the nozzle, negative pressure is applied to the internal cavity, enabling the training operation to be performed on multiple batteries simultaneously and thus improving training efficiency.

[0139] Because the nozzle is a consumable, an air leak will inevitably occur at the end of long-term use, when an air leak is detected in several nozzles of the negative pressure assembly on the tray. In the technologies concerned, generally, the nozzle extraction tool moves to the negative pressure assembly to remove all the nozzles from the entire tray at once. Then, the negative pressure assembly is removed, and the nozzle insertion tool is moved to the negative pressure assembly to replace the nozzles with new ones for all the negative pressure assemblies. However, in the actual operation, due to limited space, for example, during movement, mutual interference between the nozzle extraction tool and the insertion tool may occur. nozzle or mutual interference between the nozzle extraction tool and the nozzle insertion tool and the nozzles will be inevitable respectively.

[0140] The insertion-extraction tool 32, provided in the embodiment of this application, is configured to avoid the occurrence of mutual interference between the nozzle extraction tool and the nozzle insertion tool, or to avoid the occurrence of mutual interference between the nozzle extraction tool and the nozzle insertion tool and the nozzles respectively.

[0141] With reference to [Fig.9], [Fig.10] and [Fig.11], the insertion-extraction tool 32 comprises: a base 321, an extraction head 322 and an insertion head 323, in which, with reference to [Fig.12], [Fig.13] and [Fig.

[14] , the base 321 is configured to be disposed on a movement module 300, the extraction head 322 is disposed on the base 321, the movement module 300 is configured to drive the extraction head 322 to move towards the negative pressure assembly Al, the extraction head 322 is configured to remove the worn nozzle B1 from the negative pressure assembly Al, so that the negative pressure assembly Al is exposed to an insertion-extraction orifice Al 1, the insertion head 323 is disposed on the base 321, the insertion head 323 is configured to place a new nozzle B2, the movement module 300 is further configured to drive the insertion head 323 to move towards the negative pressure assembly Al to insert the new nozzle B2 into the insertion-extraction orifice Al.

[0142] According to this embodiment, when the worn nozzle B1 on the negative pressure assembly Al is to be replaced by the new base B2 using the insertion-extraction tool 32, firstly, the base 321 is configured to be disposed on a three-axis movement module 31, then, the three-axis movement module 31 is configured to drive the base 321 to move and thus drive the extraction head 322 disposed on the base 321 to move towards the negative pressure assembly Al, once the extraction head 322 has arrived at the negative pressure assembly Al, the extraction head 322 is configured to remove the worn nozzle B1 on the negative pressure assembly Al, so that the negative pressure assembly Al is exposed to the insertion-extraction orifice Ail.

[0143] Once the insertion-extraction orifice Al 1 is exposed to the negative pressure assembly Al, the movement module 300 is configured to drive the base 321 to move continuously and thus drive the insertion head 323 disposed on the base 321 to move towards the negative pressure assembly Al, because the new nozzle B2 is disposed on the insertion head 323, therefore, once the insertion head 323 has moved to the negative pressure assembly Al, the new nozzle B2 is configured to be inserted into the insertion-extraction orifice Al, Thus, the objective of replacing the worn nozzle B1 on the negative pressure assembly Al with the new nozzle B2 is achieved.

[0144] Because the extraction head 322 and the insertion head 323 are both arranged on the base 321, i.e., the extraction head 322 and the insertion head 323 are both integrated to be arranged on the base 321, an insertion-extraction tool 32, whose function is to remove the worn nozzle B1 and insert the new nozzle B2, is formed. Consequently, when replacing the nozzle, the same insertion-extraction tool 32 can be driven using the same motion module 300. It is not necessary to design a special tool to remove the worn nozzle B1 and a tool to insert the new nozzle B2 respectively, and it is not necessary to set up two different drives to drive the two tools to move respectively. That is, two tools can be replaced by a single insertion-extraction tool 32, thus reducing the cost.Furthermore, this prevents mutual interference between the two different drives during the movement of the two tools. Additionally, it also prevents or reduces mutual interference between the nozzle extraction tool, the nozzle insertion tool, and the worn nozzle B1 on the negative pressure assembly during movement, caused by the limited space available.Furthermore, it will be understood that once the three-axis motion module 31a drives the extraction head 322 to remove the worn nozzle B1 from the negative pressure assembly Al, the three-axis motion module 31 drives the insertion head 323 to move continuously a relatively short distance to drive the insertion head 323 towards the negative pressure assembly Al, therefore the travel time can be saved and the efficiency of replacing the worn nozzle B1 on the negative pressure assembly with the new nozzle B2 is improved.

[0145] Based on the above description, when the insertion-extraction tool 32 is applied in the nozzle replacement scenario for the negative pressure assembly, the worn nozzle B1 mentioned above is configured to be understood as the worn nozzle to be replaced on the negative pressure assembly, and the new nozzle B2 mentioned above is configured to be understood as the new nozzle. Obviously, when replacing the nozzle for the negative pressure assembly using the insertion-extraction tool 32, the same motion module 300 can be used to drive the same insertion-extraction tool 32. It is not necessary to design a special nozzle extraction tool to remove the worn nozzle and a nozzle insertion tool to insert the new nozzle, respectively. Therefore, on the one hand, the structure of the insertion-extraction tool 32 is simplified and the cost is reduced. On the other hand,the occurrence of mutual interference between the two training programs, Differentials are avoided in the process of driving the extraction tool and the insertion tool to move respectively. Furthermore, the occurrence of mutual interference between the nozzle extraction tool and the nozzle insertion tool and the worn nozzle B1 on the negative pressure assembly during movement can be avoided or reduced, which is caused by limited space for movement. In addition, this improves the efficiency of replacing the worn nozzle on the negative pressure assembly with the new nozzle.

[0146] Obviously, the scenario where the insertion-extraction tool 32 mentioned above is applied to replace the nozzle on the negative pressure assembly is only one possible scenario of the insertion-extraction tool 32 provided by the embodiment, obviously, the insertion-extraction tool 32 is also configured to be applied to other possible scenarios, when the insertion-extraction tool 32 is applied to other possible scenarios, the negative pressure assembly Al mentioned above, the worn nozzle B1 and the new nozzle B2 are also configured to be understood in other possible ways, which is not limited in this embodiment.

[0147] In addition, the worn nozzle mentioned above and the new nozzle can also be understood in their broader senses, in particular, the nozzle to be replaced can be understood as the worn nozzle, and the nozzle used to replace the worn nozzle can be understood as the new nozzle.

[0148] It should be noted that several embodiments are provided for the extraction head 32 intended to remove the worn nozzle B1 from the negative pressure assembly A1. According to one of the possible embodiments, with reference to [Fig. 10], the extraction head 322 comprises: a second seat 3221 and a stop component 322, wherein the second seat 3222 is disposed on the base 321, the second seat 3222 is provided with a cavity 32211 allowing the worn nozzle B1 to enter it, the stop component 3222 is disposed on the second seat 3221, the stop component 3222 is configured to allow the worn nozzle B1 to be inserted into the cavity 32211 in an insertion direction F3 (the negative direction of the Z-axis in [Fig. 10]) and to limit the nozzle worn B1 to exit cavity 32211 in one direction (the positive direction of the Z axis in [Fig.10]) opposite to the insertion direction F3, so that the worn nozzle B1 is removed from the negative pressure assembly Al. .

[0149] According to this embodiment, when the worn nozzle B1 on the negative pressure assembly A1 is to be removed, first, the extraction head 322 is driven by the motion module 300 to move in a direction close to the worn nozzle B1 in the opposite direction to the insertion direction F3 (the positive direction of the Z-axis in [Fig. 10]), so that the worn nozzle B1 is inserted into the cavity 32211 of the second seat 3221 in the insertion direction F3, once the worn nozzle B1 is inserted into the cavity 32211 of the second seat 3221 in the insertion direction F3, the movement module 300 is configured to drive the extraction head 322 to move in the insertion direction F3, because the stop component 3222 is configured to limit the worn nozzle B1 to exit the cavity 3221 in the opposite direction to the insertion direction F3, therefore, in the process during which the movement module 300 drives the extraction head 322 to move in the insertion direction F3, the worn nozzle B1 will follow the extraction head 322 to move in the insertion direction F3, thus the objective of removing the worn nozzle B1 from the negative pressure assembly Al can be achieved.

[0150] It can be seen that by providing the stop component 3222, the objective of removing the worn nozzle B1 from the negative pressure assembly Al can be achieved, the method of implementation is simple and the technology is mature, therefore the reliability of the operation of the extraction head 322 is guaranteed while the structure of the extraction head 322 is simplified.

[0151] In particular, an exerted force enabling the stop component 3222 to limit the worn nozzle from exiting the cavity 32211 in the direction opposite to the insertion direction F3 is configured to be provided by a spring or an elastic part, which is not limited in this embodiment.

[0152] In order to guarantee the accuracy of the position of the extraction head 322 and the insertion head 323 on the base 321, and to avoid position errors of the extraction head 322 and the insertion head 323 on the base 321 which would cause blockages in the process of extracting the worn nozzle B1 or inserting the new nozzle B2, according to certain embodiments, with reference to [Fig. 10], an extraction head positioning part and an insertion head positioning part are arranged on the base, the extraction head is arranged on the extraction head positioning part, and the insertion head is arranged on the insertion head positioning part.

[0153] By providing the extraction head 322 on the extraction head positioning part 3212, by providing the insertion head 323 on the insertion head positioning part 3213, under the action of the two positioning parts, by ensuring the accuracy of the position of the extraction head 322 and the insertion head 323 installed on the base 321, the circumstance of blocking the extraction head 322 and the insertion head 323 in the process of removing the worn nozzle B1 or inserting the new nozzle B2 is avoided.

[0154] In which, the extraction head positioning portion 3212 mentioned above is configured to be a positioning groove corresponding to the shape of the extraction head 322, the extraction head 322 is disposed in the positioning groove, or, the extraction head positioning portion 3212 is also configured to be an extraction head positioning pin, an extraction head positioning hole corresponding to the extraction head positioning pin is disposed on the extraction head 322, the extraction head positioning pin is inserted into the extraction head positioning hole, as long as the extraction head 322 can be installed accurately on the base 321, which is not limited in this embodiment.

[0155] The structure of the insertion head positioning part 3213 mentioned above is configured to be identical or similar to the structure of the extraction head positioning part 3212, referring to the description in the embodiment mentioned above on the extraction head positioning part 3212, and the structure of the insertion head positioning part 3213 will not be repeated in this embodiment.

[0156] In addition, the extraction head positioning part 3212 and the insertion head positioning part 3213 mentioned above can be made by a machining process method or any other possible methods, which is not limited in this embodiment.

[0157] According to some embodiments, with reference to [Fig. 13], the negative pressure assembly Al is plural in number, and the several negative pressure assemblies Al are arranged in a network at the interval in the first direction Fl (the X-axis direction on [Fig. 12]) and the second direction F2 (the Y-axis direction on [Fig. 13].12]), the extraction head 322 and the insertion head 323 are arranged at the interval in the first direction Fl, when the extraction head 322 moves towards any one negative pressure assembly Al of the several negative pressure assemblies Al, the insertion head 323 is arranged on one side of any one negative pressure assembly Al to avoid the negative pressure assembly Al, and / or, when the insertion head 323 moves towards any one negative pressure assembly Al of the several negative pressure assemblies Al, the extraction head 322 is arranged on one side of any one negative pressure assembly Al to avoid the negative pressure assembly Al. .

[0158] When the extraction head 322 moves towards any one of the several negative pressure assemblies Al, the insertion head 323 is positioned on one side of any negative pressure assembly Al to avoid the negative pressure assembly Al, thereby preventing mutual interference between the insertion head 323 and the negative pressure assembly Al.

[0159] When the extraction head 322 moves towards any one of the negative pressure assemblies Al, by positioning the extraction head 322 on one side of any one of the negative pressure assemblies Al to avoid the negative pressure assembly Al, which prevents the occurrence of mutual interference between the extraction head 322 and the negative pressure assembly Al.

[0160] Furthermore, by arranging the extraction head 322 and the insertion head 323 at the interval in the first direction Fl, when the worn nozzle B1 of any negative pressure assembly Al of the several negative pressure assemblies Al is to be replaced by the new nozzle B2, or the worn nozzle B1 of any column of the negative pressure assemblies Al arranged in the first direction Fl is to be replaced by the new nozzle B2, or the worn nozzle B1 of any row of the negative pressure assemblies Al arranged in the second direction F2 is to be replaced by the new nozzle B2, the replacement objective can be achieved by the mutual coordination between the extraction head 322 and the insertion head 323, thus, the objective of replacing the worn nozzle of any negative pressure assembly of the several negative pressure assemblies with the new nozzle can be achieved.or the objective of replacing the worn nozzle of any column of the negative pressure assemblies arranged in the first direction with the new nozzle can be achieved, or the objective of replacing the worn nozzle of any row of the negative pressure assemblies arranged in the second direction with the new nozzle can be achieved, compared with the process of the technology concerned according to which all the worn nozzles of the negative pressure assemblies on the tray assembly only can be replaced with the new nozzles at once, the insertion-extraction tool 32 provided by this embodiment can flexibly select the number of negative pressure assemblies that need to replace the old nozzles as required; therefore, the waste of consumables due to replacing the worn nozzles with the new nozzles at once can be avoided.

[0161] It should be noted that the above description, in which when the extraction head 322 moves towards any one negative pressure set Al of the several negative pressure sets Al, the insertion head 323 is disposed between two adjacent negative pressure sets Al, can be understood in one possible way: when the extraction head 322 moves towards any one negative pressure set Al of the several negative pressure sets Al, the insertion head 323 is disposed on a mirror surface of two negative pressure sets Al.

[0162] Obviously, when the extraction head 322 moves towards any one of the several negative pressure sets Al, the insertion head 323 is also configured so as not to be positioned on the mirror surface of two negative pressure sets Al, as long as no interference occurs will produce between the insertion head 323 and the negative pressure assembly Al, which is not limited in this embodiment.

[0163] Thus, the description in which the extraction head 322 mentioned above is arranged between two adjacent negative pressure sets Al and the insertion head 323 is arranged between two adjacent negative pressure sets Al, can be understood in the same way, which is not limited in this embodiment.

[0164] When the negative pressure assembly Al is plural in number and the several negative pressure assemblies Al are arranged in a network at the interval in the first direction Fl and the second direction F2, in order to improve the efficiency of replacing the worn nozzle B1 of any column of the negative pressure assemblies Al arranged in the first direction Fl by the new nozzles B2, according to certain embodiments, with reference to [Fig. 13] and [Fig.15], the extraction head 322 and the insertion head 323 are both plural in number, the multiple extraction heads 322 and the multiple insertion heads 323 are all arranged in the first direction Fl, a distance between two adjacent extraction heads 322 is equal to a distance between two adjacent negative pressure sets Al arranged along the first distance Fl, and a distance between two adjacent insertion heads 323 is equal to a distance between two adjacent negative pressure sets Al arranged along the first distance Fl. .

[0165] Because the distance between the two adjacent extraction heads 322 is equal to the distance between the two adjacent negative pressure sets Al arranged in the first distance Fl, when one extraction head 322 of the two adjacent extraction heads 322 arrives at one negative pressure set Al of the two adjacent negative pressure sets Al, the other extraction head 322 is configured to arrive at the other negative pressure set Al accurately, therefore, the several extraction heads 322 are configured to remove the worn nozzles B1 on each column of the negative pressure sets Al arranged in the first direction Fl at the same time.

[0166] Similarly, because the distance between the two adjacent insertion heads 323 is equal to the distance between the two adjacent negative pressure assemblies Al arranged in the first distance Fl, the several insertion heads 32 are configured to insert the new nozzles B2 into each column of the negative pressure assemblies Al arranged in the first direction Fl at the same time.

[0167] Because the multiple extraction heads 322 are configured to remove the worn nozzles B1 on each column of the negative pressure assemblies Al arranged in the first direction Fl simultaneously, and because the multiple insertion heads 32 are configured to insert the new nozzles B2 into each column of the negative pressure assemblies Al arranged in the first direction At the same time, the efficiency of replacing the worn nozzle B1 on each column of the negative pressure assemblies Al arranged in the first direction Fl with the new nozzle B2 can be improved.

[0168] When the extraction head 322 and the insertion head 323 are both in the plural, the multiple extraction heads 322 and the multiple insertion heads 323 are all arranged in the first direction Fl, referring to [Fig. 16], a group of extraction heads 3220 is formed by the multiple extraction heads 322, a group of insertion heads 3230 is formed by the multiple insertion heads 323, and the group of extraction heads 3220 and the group of insertion heads 3230 are arranged sequentially in the first direction Fl, or referring to [Fig. 15], at least one extraction head 322 of the multiple extraction heads 322 is arranged between two adjacent insertion heads 323.

[0169] When the extraction head group 3220 and the insertion head group 3230 are arranged sequentially in the first direction Fl, the several extraction heads 322 are configured to be concentrated and placed together, the several insertion heads 323 are configured to be concentrated and placed together, in this way, on the one hand, the arrangement of the extraction head 322 and the insertion head 323 is relatively organized, thus facilitating the manufacturing process, on the other hand, the extraction head 322 and the insertion head 323 are configured to be spaced further apart, thus avoiding or reducing mutual interference between the worn nozzle B1 removed by the extraction head 322 and the new nozzle B2 placed on the insertion head 323.

[0170] When at least one extraction head 322 of the several extraction heads 322 is arranged between the two adjacent extraction heads 323, on the one hand, the space between the two adjacent extraction heads 322 can be well used by the insertion head, so that the structure of the whole insertion-extraction tool 32 is configured to be relatively compact.On the other hand, once the worn nozzle B1 on the negative pressure assembly Al is removed by the extraction head 322, the insertion head 323 is brought to the negative pressure assembly Al as long as the movement module 300 drives the base 321 to move a certain distance from the space between the extraction head 322 and the insertion head 323 in the first direction Fl, the distance of movement is relatively short, therefore the efficiency of replacing the worn nozzle B1 on the negative pressure assembly Al with the new nozzle B2 can be further improved.

[0171] Obviously, the multiple extraction heads 322 and the multiple insertion heads 323 are further configured to be arranged in the first direction Fl in other possible ways, for example, some of the extraction heads 322 of the multiple extraction heads 322 are configured to be arranged in the first direction Fl, and the remaining part of the extraction heads 322 and the several insertion heads 323 are arranged in the first direction Fl in an interlaced manner, which is not limited in this embodiment.

[0172] According to some embodiments, with reference to [Fig.13] and [Fig.15], the number of multiple extraction heads 322 is equal to the number of negative pressure assemblies Al arranged in the first direction Fl in each column, and / or, the number of multiple insertion heads 323 is equal to the number of negative pressure assemblies Al arranged in the first direction of each column.

[0173] By setting the number of multiple extraction heads 322 to be equal to the number of negative pressure assemblies Al arranged in the first direction Fl of each column, the worn nozzles B2 on the negative pressure assembly Al arranged in the first direction Fl of each column are configured to be removed by the multiple insertion heads 322 in one go, therefore the efficiency of the extraction of the worn nozzles B1 on the negative pressure assembly Al can be improved.

[0174] By setting the number of several extraction heads 323 to be equal to the number of negative pressure assemblies Al arranged in the first direction Fl of each column, the new nozzles B2 are configured to be inserted into the negative pressure assemblies Al respectively by the several insertion heads 322 in one go, therefore the efficiency of the insertion of the new nozzles B2 into the negative pressure assembly Al can be improved.

[0175] In order to store the worn nozzle B1 removed by the extraction head 322 temporarily, according to certain embodiments, with reference to [Fig.9] and [Fig.11], the insertion-extraction tool 32 further includes a temporary storage assembly 324, the temporary storage assembly 324 is configured to temporarily store the worn nozzle B1 removed by the extraction head 322 in the temporary storage assembly 324.

[0176] By providing the temporary storage assembly 324, the worn nozzle B1 removed by the extraction head 322 is configured to be temporarily stored in the temporary storage assembly 324, in this way, on the one hand, the extraction head 322 can be freed to perform the work of extracting the worn nozzle B1 continuously, on the other hand, the occurrence of the circumstance where the worn nozzle B1 is placed on the extraction head 322 for a long time is avoided, such circumstance causing it to fall and risking damage to other components or to the worn nozzle B1 itself.

[0177] According to some embodiments, with reference to [Fig. 10], the base 321 is provided with a through hole 3211 penetrating the base 321, at least part of the structure of the temporary storage assembly 324 is arranged vertically below the hole through 3211, the through hole 3211 is configured to allow the worn nozzle B1 removed by the extraction head 322 to fall into the temporary storage assembly 324 through the through hole 3211.

[0178] Because at least part of the structure of the temporary storage assembly 324 is arranged vertically under the through hole 3211, therefore, when the worn nozzle B1 is removed by the extraction head 322 under the action of gravity, the worn nozzle B1 is configured to automatically pass through the through hole 3211 and fall into the temporary storage assembly 324 for temporary storage, it is not necessary to design a special structure to transport the worn nozzle B1 to the temporary storage assembly 324 for temporary storage, therefore, the structure of the insertion-extraction tool 32 can be simplified.

[0179] Furthermore, because the worn nozzle B1 removed by the extraction head 322 is configured to fall into the temporary storage assembly 324 through the through hole 3211, the through hole 3211 is configured to play a role in guiding the worn nozzle B1 in the process of the worn nozzle B1 falling into the temporary storage assembly 324, which prevents the occurrence of the circumstance where the worn nozzle B1 deviates in the process of falling into the temporary storage assembly 324, such circumstance causing a failure of the fall into the temporary storage assembly 324.

[0180] Wherein, the shape of the through hole 3211 mentioned above is configured to be circular, square or other, and the shape of the through hole 3211 is not limited in this embodiment.

[0181] Several embodiments are provided for the temporary storage assembly 324 mentioned above; in one of the possible embodiments, with reference to [Fig.11], the temporary storage assembly 324 comprises: a drive component 3241 and a cache component 3242, wherein the drive component 3241 is disposed on the base 321, the cache component 3242 is connected to the drive component 3241, the drive component 3241 is configured to drive the cache component 3242 to move vertically to the position under the through hole 3211 or to move vertically away from the position under the through hole 3211, to open or protect the through hole 3211.

[0182] Because the drive component 3241 is disposed on the base 321 and the cover component 3242 is connected to the drive component 3241, when the used nozzle B1 needs to be temporarily stored, the drive component 3241 is configured to drive the cover component 3242 to move vertically under the through hole 3211. The through hole 3211 is covered by the cover component 3242. In this way, during the process of the used nozzle B1 falling through the hole passing through 3211, the cache component 3242 is configured to prevent the worn nozzle B1 from continuing to fall, the worn nozzle B1 is held on the cache component 3242, thus the objective of temporarily storing the worn nozzle B1 can be achieved.

[0183] When the worn nozzle B1 is to continue falling, the drive component 3241 is configured to drive the cache component 3242 to move until the cache component 3242 moves vertically away from the position under the through hole 3211, the through hole 3211 is opened, in this way the worn nozzle B1 can pass through the through hole 3211 to continue falling after the opening of the through hole 3211.

[0184] It can be seen that when the temporary storage assembly 324 includes the drive component 3241 and the cache component 3242, the cache component 3242 is driven by the drive component 3241 to move vertically under the through hole 3211 or to move vertically away from the position under the through hole 3211, which allows free switching between the two modes of temporary storage of the worn nozzle B1 or stopping the temporary storage of the worn nozzle Bl, which is very flexible.

[0185] Wherein, the drive component 3241 mentioned above is configured to be an air cylinder, an electric cylinder, or other such components, which are not limited in this embodiment. The cover component 3242 mentioned above is configured to be a cover plate or other possible structures, which are not limited in this embodiment.

[0186] Obviously, the temporary storage assembly 324 is further configured to be implemented by other possible modes, for example, in another possible implementation mode, the temporary storage assembly 324 includes a temporary storage box, and the temporary storage box is arranged vertically under the through hole 3211.

[0187] Because the temporary storage box is arranged vertically under the through hole 3211, therefore the worn nozzle B1 continuing to fall through the through hole 3211 can enter the temporary storage box, thus the objective of temporarily storing the worn nozzle B1 in the temporary storage box can be achieved.

[0188] Because the structure of the temporary storage box is simple, the cost of the entire temporary storage 324 can be reduced.

[0189] In which, the shape of the temporary storage box is configured to be cylindrical, cuboid or other possible shapes, and the shape of the temporary storage box is not limited in this embodiment.

[0190] According to this embodiment, because the insertion-extraction tool 32 can reduce the cost, the insertion-extraction tool 32 can prevent the occurrence of the mutual interference between two different drives in the process of driving the two tools to move respectively, the insertion-extraction tool 32 can avoid or reduce the occurrence of mutual interference between the two tools and the worn nozzle B1 on the negative pressure assembly Al in the process of movement, and at the same time, the insertion-extraction tool 32 can improve the efficiency of replacing the worn nozzle B1 on the negative pressure assembly Al with the new nozzle B2.

[0191] The motion module 300 mentioned above is configured to be a three-axis XYZ module, a robotic arm or other, and the motion module 300 is not limited in this embodiment.

[0192] Finally, it should be noted that the above embodiments are used only to illustrate the technical solutions of the present application, instead of limiting it; although the present application has been described in detail with reference to the above-mentioned embodiments, those skilled in the art will understand that: The technical solutions described in the preceding embodiments may still be modified, or some or all of the technical features may be replaced in an equivalent manner; and such modifications or replacements do not depart from the spirit of the corresponding technical solutions of the embodiments of the present application.
