Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 14 in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The application provides a nail inserting device which is applied to the nail inserting operation of a lithium battery.

In the related art, a large amount of electrolyte is contained in the lithium battery, the electrolyte is injected into the lithium battery, a liquid injection port is required to be reserved on the surface of a lithium battery shell, and after the liquid injection is completed, the liquid injection port is required to be plugged through a sealing nail (also called a glue nail) so as to prevent the electrolyte injected into the lithium battery from volatilizing. The pin inserting device is used for automatically inserting the pins into the liquid injection port of the lithium battery, namely, the pin inserting device is applied to automatically inserting the sealing pins into the liquid injection port of the lithium battery, so that the pin inserting efficiency can be improved.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a nail inserting apparatus according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a casing of a hidden portion of a nail inserting apparatus according to an embodiment of the present application. The plug pin apparatus 10 includes a housing 600, a feeding mechanism 100, a conveying mechanism 200, a jacking mechanism 300, and a plug pin mechanism 400.

Wherein the housing 600 is identical to the external contour of the pin inserting apparatus 10 to accommodate the internal mechanism, apparatus or external product of the pin inserting apparatus 10, while the housing 600 serves as a main body frame of the pin inserting apparatus 10 for positioning, supporting and carrying the internal mechanism, apparatus or external product of the pin inserting apparatus 10.

The feeding mechanism 100 is used for feeding and conveying sealing nails to the nail inserting mechanism 400, and the specific contents of the feeding mechanism 100 will be described in detail below.

The transport mechanism 200 is used to transport lithium batteries. Specifically, the conveying mechanism 200 may be directly connected to an upstream lithium battery production device to form one ring in the lithium battery production line, and the lithium battery manufactured upstream may be directly conveyed to a preset dowel station through the conveying mechanism 200. Of course, the conveying mechanism 200 may be a separate mechanism, that is, the conveying mechanism 200 may not be connected to an upstream lithium battery production device, for example, in some cases, the dowel device 10 is not convenient to be disposed at a site close to a lithium battery production line, and then the lithium battery may be transported to the conveying mechanism 200 by another transport carrier, and then the lithium battery is conveyed to a preset dowel station by the conveying mechanism 200.

As shown in fig. 1, the casing 600 is provided with an opening 610 through which at least part of the transfer mechanism 200 is exposed, so that external lithium batteries are transferred to the transfer mechanism 200 through the opening.

Referring to fig. 3, fig. 3 is an assembly schematic diagram of a conveying mechanism and a pin inserting mechanism according to an embodiment of the application. The transfer mechanism 200 includes a plurality of transfer rollers 210 arranged at intervals along the first direction. Wherein the first direction is along the conveying direction of the conveying mechanism 200, i.e. the conveying direction of the plurality of conveying rollers 210.

In the description of the present application, it should be understood that terms such as "first," "second," and the like are used merely to distinguish between similar objects and should not be construed to indicate or imply relative importance or implying any particular order of magnitude of the technical features indicated.

The lithium battery may be directly placed on the transfer drum 210 for transfer, i.e., the lithium battery is directly in contact with the outer surface of the transfer drum 210, or the lithium battery may be placed on a carrying structure such as a tray, and the lithium battery is indirectly transferred by transferring the carrying structure such as the tray through the transfer mechanism 200.

Illustratively, in one embodiment, the dowel apparatus 10 is further configured with a tray (not shown) for carrying lithium batteries, and the tray may be provided with a structure for positioning and fixing the lithium batteries, and the lithium batteries are used for being transported by placing the tray on the transport roller 210, so as to ensure stability of the transportation process of the lithium batteries, and protect the lithium battery case while preventing the lithium batteries from toppling over. Moreover, the tray is used for bearing the lithium batteries, and a plurality of lithium batteries can be borne on the tray, so that the nail inserting device 10 can simultaneously insert nails for a plurality of lithium batteries.

The pin inserting mechanism 400 is used for inserting pins for a lithium battery. Specifically, the pin inserting mechanism 400 may perform a pin inserting operation on the lithium battery when the lithium battery is transferred to a preset position such as a pin inserting station by the transfer mechanism 200.

With continued reference to fig. 3, the pin inserting mechanism 400 may include a moving assembly 410, and a material taking assembly 420 and a nailing assembly 430 connected to the moving assembly 410, where the moving assembly 410 is used to drive the material taking assembly 420 and the nailing assembly 430 to move. The moving assembly 410 is configured to drive the material taking assembly 420 to move between the feeding station and the pin inserting station, so that the material taking assembly 420 picks up the sealing pin conveyed by the feeding mechanism 100 at the feeding station, and the material taking assembly 420 places the sealing pin into the liquid injection port of the lithium battery at the pin inserting station. The moving assembly 410 is used for driving the nailing assembly 430 to move so that the nailing assembly 430 is aligned with the liquid injection port of the lithium battery, and the nailing assembly 430 inserts the sealing nail into the liquid injection port of the lithium battery.

The moving component 410 may be a moving device such as a manipulator, an industrial robot, or a multi-axis moving module.

The material taking assembly 420 may be a clamping structure, for example, the material taking assembly 420 may employ clamping jaws, and the clamping force formed by the clamping jaws clamps the sealing nail provided by the feeding mechanism 100; the material taking assembly 420 may also be a suction type structure, for example, the material taking assembly 420 may use a negative pressure suction nozzle to suck the sealing nail provided by the feeding mechanism 100 under the negative pressure.

The nailing assembly 430 can be a pressing structure, and the pressing of the sealing nail into the liquid injection port of the lithium battery is realized by applying a certain pressure to the sealing nail placed at the liquid injection port of the material taking assembly 420. Of course, other types of constructions for the nailing assembly 430 are also possible.

It can be appreciated that the contact area that the transmission roller 210 can provide is smaller, and the transmission roller 210 is easy to rotate under the action of external force, if the pin inserting mechanism 400 directly inserts the pin into the lithium battery carried on the transmission roller 210, when inserting the pin into the lithium battery, the pin inserting mechanism 400 applies a certain acting force to the lithium battery, the lithium battery transfers the acting force to the transmission roller 210, and the transmission roller 210 easily drives the lithium battery to move, so that the pin inserting mechanism 400 cannot be aligned with the liquid injection port of the lithium battery, and smooth operation of the pin inserting device 10 cannot be ensured. In this regard, some mechanisms, such as a pressing mechanism, may be provided to press the lithium battery to restrict movement of the lithium battery, or some mechanisms may be provided to prevent the transfer drum 210 from contacting the lithium battery, when the nailing operation is performed.

Illustratively, the dowel apparatus 10 of the present application is provided with a jacking mechanism 300, and the jacking mechanism 300 is used to jack the lithium battery to a preset height, so that the lithium battery is separated from the carrier of the transport roller 210.

It should be noted that, the lifting mechanism 300 may directly or indirectly lift the lithium battery to a certain height, for example, when the lithium battery is transported on the transport mechanism 200 through a bearing structure such as a tray, the lifting mechanism 300 may lift the whole of the lithium battery and the tray to a certain height, so that the tray and the lithium battery are integrally separated from the bearing of the transport roller 210, i.e., the lifting mechanism 300 indirectly lifts the lithium battery to a certain height.

Illustratively, in one embodiment, the lithium battery is transported on the transport mechanism 200 by a tray, and the following description will be given mainly taking the case that the lithium battery is transported on the transport roller 210 by a tray as an example.

According to the embodiment of the application, the lifting mechanism 300 is arranged, and the lithium battery is lifted to the preset height through the lifting mechanism 300, so that the lithium battery is separated from the bearing of the transmission roller 210, the movement of the lithium battery driven by the transmission roller 210 is avoided, the lifting mechanism 300 can always maintain the lithium battery at a certain position, the actuating component of the dowel equipment 10 can be accurately and easily aligned with the liquid injection port of the lithium battery, and the smooth performance of dowel operation can be ensured. Moreover, through setting up climbing mechanism 300 with the lithium cell lifting, climbing mechanism 300 is holding in the palm the holding force to the lithium cell effect, compares in setting up hold-down mechanism and compresses tightly the lithium cell and restrict the lithium cell removal, climbing mechanism 300 can not lead to the fact the pressure to the lithium cell shell, can prevent that the lithium cell shell from taking place to warp, can not lead to the fact the damage to the lithium cell, avoids causing the influence to the use of lithium cell.

To ensure stability of the jacking process, in an embodiment of the present application, the dowel apparatus 10 may include at least two jacking mechanisms 300.

It can be appreciated that by setting at least two jacking mechanisms 300, the at least two jacking mechanisms 300 cooperate together, so that the tray and the lithium battery carried on the tray can be stably supported and lifted, the stability of the tray and the lithium battery in jacking movement can be ensured, and the falling of the lithium battery caused by the falling of the tray is prevented. And, because when climbing mechanism 300 is with tray and lithium cell lifting, some positions of tray are in the unsettled state, and these positions have born the weight of lithium cell again, through setting up two at least climbing mechanism 300, then climbing mechanism 300 can contact with two at least positions on the tray, prevent that some positions of tray atress from concentrating excessively and leading to the tray deformation even fracture.

The number of the jacking mechanisms 300 may be two, three or more, the specific number of the jacking mechanisms 300 may be set according to the size of the tray, the number or weight of lithium batteries carried by the tray, and when the size of the tray is larger, the number of lithium batteries carried on the tray is larger, or the weight is heavier, the number of the jacking mechanisms 300 should be correspondingly set to be larger. The number of jacking mechanisms 300 in the drawings of the present embodiment is for illustration only and is not to be construed as limiting the present application.

Since the lithium battery performs the pin inserting operation inside the pin inserting device 10, the lithium battery needs to occupy a part of the internal space of the pin inserting device 10, and the pin inserting device 10 has more internal mechanisms, when the number of the jacking mechanisms 300 is larger, the whole volume of the pin inserting device 10 is very large, and the occupied space is more.

In order to solve the above-mentioned problems, please refer to fig. 4 in the embodiment of the present application, fig. 4 is an assembly schematic diagram of the transmission mechanism and the lifting mechanism according to the embodiment of the present application. At least two jacking mechanisms 300 are arranged at intervals along the first direction, and at least one jacking mechanism 300 is arranged between two adjacent conveying rollers 210.

Specifically, the jacking mechanism 300 is disposed between two adjacent transmission rollers 210, and there are at least two cases in which an avoidance gap is originally provided between two adjacent transmission rollers 210 of the transmission mechanism 200 to prevent the two adjacent transmission rollers 210 from contacting friction to affect transmission, and the jacking mechanism 300 can be disposed in the partial gap, thereby utilizing a space that is not originally available and not requiring an additional space for installing the jacking mechanism 300; alternatively, the middle transfer roller 210 may be removed from the adjacent three transfer rollers 210 of the transfer mechanism 200, and the jacking mechanism 300 may be mounted on the empty space of the removed transfer roller 210, so that no additional space for mounting the jacking mechanism 300 is required, and the removal of one of the transfer rollers 210 does not affect the normal operation of the transfer mechanism 200.

It should be noted that, in the first case, the portion of the jacking mechanism 300 for performing the jacking function is designed to be relatively small in volume, and for example, the portion may be designed to be columnar or rod-like, enabling to be disposed in the gap between the adjacent two rollers.

According to the dowel inserting device 10, the feeding mechanism 100 is arranged to provide sealing nails for the dowel inserting mechanism 400, the conveying mechanism 200 is provided with the conveying roller 210 to convey lithium batteries, the jacking mechanism 300 is used for jacking the lithium batteries to a preset height so that the dowel inserting mechanism 400 can insert the lithium batteries, the jacking mechanism 300 lifts the lithium batteries to be separated from the bearing of the conveying roller 210, the conveying roller 210 is prevented from driving the lithium batteries to move, the jacking mechanism 300 can always maintain the lithium batteries at a certain position, the executing components of the dowel inserting device 10 can be accurately and easily aligned with the liquid injection ports of the lithium batteries, and smooth dowel inserting operation can be ensured. Moreover, the at least one jacking mechanism 300 is arranged between the two adjacent transmission rollers 210, and the gap between the two adjacent transmission rollers 210 is utilized or the installation space of the transmission rollers 210 is directly utilized, so that the installation space is not required to be additionally arranged for at least one jacking mechanism 300 of the pin inserting device 10, the occupation of the internal space of the pin inserting device 10 can be reduced, the whole volume of the pin inserting device 10 can be reduced, and the occupation of the field space can be reduced.

It should also be noted that the top height of the jacking mechanism 300 before the jacking movement is lower than the top height of the outer cylindrical wall of the transfer drum 210 to avoid interference with the transfer of the lithium battery.

Alternatively, in one embodiment, the number of jacking mechanisms 300 is two, and each jacking mechanism 300 is disposed between two adjacent conveying rollers 210. Illustratively, in an embodiment, the transport mechanism 200 includes a first end 200a and a second end 200b opposite in a first direction, one of the climbing mechanisms 300 may be disposed between two adjacent transport rollers 210 proximate the first end 200a, and the other climbing mechanism 300 may be disposed between two adjacent transport rollers 210 proximate the second end 200 b. It should be noted that, in the present embodiment, the conveying mechanism 200 includes at least three conveying rollers 210.

Specifically, in practical application, a certain number of conveying rollers 210 may be configured according to the conveying requirement of the nail inserting apparatus 10 to form a conveying mechanism 200 with a certain conveying distance, then, among the plurality of conveying rollers 210 of the conveying mechanism 200, two conveying rollers 210 which are not adjacent to each other are taken out, for example, two conveying rollers 210 which are far away from each other are taken out, and two jacking mechanisms 300 are respectively installed at the positions of the conveying mechanism 200 which are free from the corresponding two conveying rollers 210, so that the jacking mechanisms 300 utilize the installation space of the original conveying rollers 210, and the installation space is not additionally set for the jacking mechanisms 300, thereby reducing the occupation of the internal space of the nail inserting apparatus 10, relatively reducing the volume of the nail inserting apparatus 10, and since only two mutually non-adjacent conveying rollers 210 are removed, the rest conveying rollers 210 can still roll normally, the conveying mechanism 200 can still realize effective conveying of lithium batteries without affecting the conveying performance of the conveying mechanism 200.

Alternatively, in one embodiment, the number of jacking mechanisms 300 is two, wherein one jacking mechanism 300 is disposed between two adjacent conveying rollers 210, and the other jacking mechanism 300 is disposed at an end of the conveying mechanism 200 along the conveying direction thereof.

For example, in one embodiment, referring to fig. 4, the conveying mechanism 200 includes a first end 200a, and an avoidance space (not shown) is disposed between the conveying roller 210 near the first end 200a and the first end 200a, where one jacking mechanism 300 is disposed.

The transfer roller 210 near the first end 200a refers to the transfer roller 210 closest to the first end 200a in the transfer mechanism 200.

Specifically, the first end 200a may be a distal end, or trailing end, of the transport mechanism 200. For example, the transfer mechanism 200 may include a first end 200a and a second end 200b opposite in a first direction, the second end 200b being an input end of the transfer mechanism 200, the lithium battery being for transfer from the second end 200b into the transfer mechanism 200, a side of the first end 200a remote from the second end 200b may be provided with a blocking structure such that the first end 200a acts as a terminating end of the transfer mechanism 200, and the transfer mechanism 200 stops transferring the lithium battery close to the first end 200a from moving. To integrally transfer the lithium battery and the tray to the first end 200a, the transfer of the lithium battery by the transfer roller 210 near the first end 200a is not great mainly by the transfer of the transfer roller 210 far from the first end 200 a. Then, the small area extending from the first end 200a to the second end 200b may not be provided with the transmission roller 210, so that an avoidance space is formed between the transmission roller 210 near the first end 200a and the first end 200a, and by setting the jacking mechanism in the avoidance space, an installation space is not required to be additionally provided for the jacking mechanism, so that occupation of the internal space of the nail insertion device 10 may be further reduced.

Alternatively, in one embodiment, the number of the jacking mechanisms 300 is three, wherein two jacking mechanisms 300 are respectively disposed between two adjacent two conveying rollers 210, and the other jacking mechanism 300 is disposed at an end of the conveying mechanism 200 along the conveying direction thereof.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a lifting mechanism according to an embodiment of the application. The jacking mechanism 300 comprises a first supporting plate 310 and a first driving piece 320, the first supporting plate 310 is used for supporting the lithium battery, the first driving piece 320 is connected with the first supporting plate 310, the first driving piece 320 is used for driving the first supporting plate 310 to move along a second direction so as to jack the lithium battery to a preset height, and the second direction is perpendicular to the first direction.

It will be appreciated that for better lifting of the lithium battery and tray off the carrier of the transport mechanism 200, the second direction is a direction perpendicular to the contact surface of the transport roller 210 with the lithium battery (or tray), i.e. the second direction is a vertical direction.

The first driving member 320 may be a linear driving device such as an air cylinder, an electric cylinder, an oil cylinder, etc., which is not limited in the embodiment of the present application. Wherein the first driving member 320 may be fixedly mounted on the table 620 of the cabinet 600.

With continued reference to fig. 5, the first support plate 310 includes a support surface 311 and a positioning pin 312 protruding from the support surface 311, where the support surface 311 is used for supporting a lithium battery, and the positioning pin 312 is used for positioning and matching the lithium battery.

The locating pins 312 are designed to mate with structures on the tray, such as locating holes, to indirectly effect locating of the lithium batteries on the tray by locating the tray on the first support plate 310. Of course, in other alternative embodiments of the present application, the locating pins 312 may also be designed to mate with structures on the lithium battery, such as locating holes, to locate the lithium battery on the first support plate 310.

It can be appreciated that, through setting up locating pin 312 and being used for carrying out location cooperation with the lithium cell, through the positioning action of locating pin 312, can be with the lithium cell location in the position of predetermineeing to the operation of other mechanisms of follow-up cooperation of being convenient for, locating pin 312 can also play the limiting displacement simultaneously, can guarantee that the lithium cell is firm to be supported on first backup pad 310.

Taking the example of lithium battery being transported on the transport mechanism 200 via a tray, the positioning pins 312 are used to match with the positioning hole structure on the tray. Specifically, in the process of integrally lifting the tray and the lithium battery by the lifting mechanism 300, when the positioning pin 312 is not matched with the tray in place, the positioning pin 312 can lift the tray, so that a gap exists between the bottom surface of the tray and the micro switch 340, the micro switch 340 cannot sense the tray, and at the moment, the micro switch 340 sends a signal to the control system of the pin inserting device 10, so that the pin inserting device 10 sends an alarm to remind an operator to manually adjust the tray in place; when the locating pin 312 is matched with the tray in place, the locating pin 312 is inserted into the locating hole structure of the tray, at the moment, the bottom surface of the tray is completely contacted with the supporting surface 311 of the first supporting plate 310, the micro switch 340 is pressed down by the bottom surface of the tray, so that the micro switch 340 senses the tray, and the fact that the tray is matched with the locating pin 312 in place can mean that follow-up pin inserting operation can be performed.

The limiting member 510 is provided with a clamping groove 510a for inserting a lithium battery, and the clamping groove 510a is used for being in clamping fit with the outer side wall of the lithium battery. The second driving piece 520 is connected with the limiting piece 510, and when the jacking mechanism 300 jacks up the lithium battery to a preset height, the second driving piece 520 is used for driving the limiting piece 510 to move close to the lithium battery, so that the limiting piece 510 performs clamping limiting on the lithium battery through the clamping groove 510 a.

Referring to fig. 2, the feeding mechanism 100 includes a vibration plate 110, a stapling device 120, and a feeding device 130.

Wherein a large number of seal staples may be stored within the vibratory tray 110. The vibration plate 110 is used to sequentially arrange and feed out a plurality of sealing nails stored therein one by the vibration action of the vibration plate itself.

The stapling apparatus 120 is used to dispense the sealing staples provided by the vibratory tray 110. It has been pointed out above that, in order to improve the production efficiency, the pin inserting mechanism 400 may be designed to insert a plurality of sealing pins simultaneously for a plurality of lithium battery liquid injection ports, i.e. the pin inserting mechanism 400 may insert a plurality of sealing pins simultaneously at a time, and then a plurality of sealing pins need to be conveyed for the pin inserting mechanism 400 in one pin inserting action. The nail separating device 120 can distribute the plurality of sealing nails provided by the vibration disc 110 into multiple paths (namely, different paths are conveyed), and can respectively convey the plurality of sealing nails to different material taking positions set on the downstream feeding device 130, so that the nail inserting mechanism 400 can pick up the plurality of sealing nails at one time and simultaneously insert nails, and the production efficiency is improved.

The feeding device 130 is configured to receive the plurality of sealing nails distributed by the nail separating device 120, and is configured to place the plurality of sealing nails in a correct posture (a posture required for plugging the battery liquid injection port) so as to provide smooth material taking by the material taking component 420 of the nail inserting mechanism 400. The stapling device 120 and the feeding device 130 will be described in detail with reference to the drawings.

Referring to fig. 9 and 10, fig. 9 is a schematic structural diagram of a nail separating device according to an embodiment of the present application, and fig. 10 is a cross-sectional view of a nail separating device according to an embodiment of the present application. The staple separating device 120 includes a feed tube 121, a staple separating plate 122, a first fixing plate 123 and a third driving member 124.

The feed tube 121 is used to deliver sealing nails. The feed tube 121 may be in communication with the vibratory pan 110 to receive sealing nails delivered by the vibratory pan 110. Moreover, the vibration plate 110 continuously conveys out the sealing nails in the vibration plate 110 through continuous vibration, so that the sealing nails of the feeding pipe 121 move in the feeding pipe 121 under the pushing action of the sealing nails at the back.

The first fixing plate 123 may be fixedly mounted on the working platen 620 of the casing 600 through a bracket, the nail separating plate 122 is disposed on one side of the first fixing plate 123, the nail separating plate 122 is provided with a plurality of receiving holes 1221 penetrating through the thickness direction of the nail separating plate 122, the plurality of receiving holes 1221 are disposed at intervals along the same direction, the third driving member 124 is mounted on the first fixing plate 123 and is in driving connection with the nail separating plate 122, and the third driving member 124 is used for driving the nail separating plate 122 to reciprocate relative to the feeding tube 121, so that the plurality of receiving holes 1221 are sequentially communicated with the feeding tube 121, and a plurality of sealing nails conveyed by the feeding tube 121 sequentially enter the plurality of receiving holes 1221.

In this way, the third driving piece 124 drives the nail separating plate 122 to move, so that the plurality of containing holes 1221 are sequentially communicated with the feeding pipe 121 when the nail separating plate 122 moves, so that one sealing nail output by the feeding pipe 121 can enter different containing holes 1221, and the distribution of the sealing nails can be realized.

In order to convey the seal nails dispensed into the different receiving holes 1221 to the different material taking positions of the downstream feeding device 130, please continue to refer to the drawing, the first fixing plate 123 is provided with a plurality of first through holes 1231 penetrating the thickness direction of the first fixing plate 123, and the plurality of first through holes 1231 are disposed at intervals. Each of the receiving holes 1221 is in turn in communication with one of the first through holes 1231 during movement of the staple separating plate 122 driven by the third driving member 124.

That is, the first fixing plate 123 serves to receive the seal staples dispensed from the staple separating plate 122 through the first through holes 1231. Specifically, each first through hole 1231 may be connected to a different feed tube 125, and the seal pin in the receiving hole 1221 may be delivered to a different take-out location on the downstream feeding device 130 via the first through hole 1231, the feed tube 125.

Because the sealing nails in the feeding pipe 121 are moved in the feeding pipe 121 by the thrust of the rear sealing nails, the front sealing nails and the rear sealing nails are always connected end to end in the moving process. When the feeding tube 121 is in communication with one of the receiving holes 1221, the rear sealing nail pushes the front sealing nail completely into the receiving hole 1221, and the separating nail plate 122 can move to distribute the sealing nail, before the separating nail plate 122 moves, since the front sealing nail and the rear sealing nail are always connected end to end, the rear sealing nail also has a small part to enter the receiving hole 1221, that is, the rear sealing nail does not enter the receiving hole 1221, in other words, the feeding tube 121 has the sealing nail which does not enter the receiving hole 1221 in the conveying process, and the receiving hole 1221 is driven to be in a moving state when the separating nail plate 122 moves, the rear sealing nail is in a static state (namely, relatively static in the moving direction of the separating nail plate 122), so that the part of the rear sealing nail extending into the receiving hole 1221 can interfere with the moving receiving hole 1221, the condition of the clamping nail is easy to cause the clamping nail, and the problem of stopping and seriously affecting the feeding efficiency by manually releasing the clamping nail is needed when the clamping nail occurs.

In this regard, in an embodiment, referring to fig. 10, the staple separating plate 122 is further provided with a avoiding groove 1222, the avoiding groove 1222 is communicated with each receiving hole 1221, and a notch of the avoiding groove 1222 is disposed toward the feeding pipe 121.

Dodge the notch direction orientation of groove 1222 to the material pipe 121, dodge the groove 1222 promptly and set up in the side that divides the nail board 122 to face to the incoming material pipe 121, through setting up dodge groove 1222 and every accommodation hole 1221 intercommunication, when the motion of third driving piece 124 drive divides the nail board 122, divide the nail board 122 to drive dodge groove 1222 and follow accommodation hole 1221 and move together, dodge the position that groove 1222's wherein part can move to accommodation hole 1221 originally was located, then, to the back sealing nail with accommodation hole 1221 internal seal nail end to end, it originally stretches into the part of accommodation hole 1221 and can get into dodge in the groove 1222, realize dodging the effect, can prevent to divide the nail board 122 in-process back sealing nail and accommodation hole 1221 to take place to interfere and cause the condition of staple, can improve the problem of staple, improve feed efficiency.

In some cases, the junction of the feed tube 125 and the first through hole 1231 is located at a lower level than the material taking location of the downstream feeding device 130, so that the sealing nails entering the feed tube 125 can be fed to the feeding device 130, in an embodiment, the nailing device 120 further includes a second fixing plate 126 and a plurality of air nozzles 127.

As shown in fig. 9, the second fixing plate 126 is disposed on a side of the nail separating plate 122 facing away from the first fixing plate 123, and the second fixing plate 126 is provided with a plurality of second through holes 1261 penetrating through the thickness direction of the second fixing plate 126, and each second through hole 1261 is disposed opposite to one first through hole 1231. Each air tap 127 is in communication with a second through hole 1261.

Specifically, when the third driving member 124 drives the nail separating plate 122 to move to one of the accommodating holes 1221 and one of the first through holes 1231, since each of the second through holes 1261 is opposite to one of the first through holes 1231, then the second through holes 1261 will also be in communication with the accommodating hole 1221, and the air nozzle 127 blows air into the accommodating hole 1221, so that the sealing nail in the accommodating hole 1221 can be blown into the feeding tube 125 through the first through hole 1231 and is continuously blown along the feeding tube 125 to the downstream feeding device 130.

The second fixing plate 126 may further be provided with a third through hole penetrating through the thickness direction of the second fixing plate, and the output pipe orifice of the feeding pipe 121 may be disposed through the third through hole (or be connected and matched with the third through hole) so as to limit the feeding pipe 121.

In order to further improve the smoothness of conveying the sealing nails, in an embodiment, one end of the feeding pipe 121, which is close to the nail separating plate 122, may be inclined downward, or bent downward, and correspondingly, the nail separating plate 122 is inclined, so that when the sealing nails are conveyed to the end of the feeding pipe 121, which is close to the nail separating plate 122, the sealing nails can quickly slide into the accommodating holes 1221 of the nail separating plate 122 under the action of gravity, thereby improving the smoothness of conveying the sealing nails and further improving the feeding efficiency.

Referring to fig. 11, fig. 11 is a schematic structural diagram of a feeding device according to an embodiment of the present application. The feeding device 130 comprises a feed tube 131 and a receiving member 132.

The feed pipe 131 is connected to the end of the feed pipe 125 to feed the sealing nails fed from the feed pipe 125. The receiving member 132 is disposed at one side of the feeding tube 131 and has a receiving hole 1321, and the receiving member 132 is used for receiving the sealing nail conveyed by the feeding tube 131, so that the nail inserting mechanism 400 can clamp the sealing nail from the receiving member 132 to insert nails.

Because the vibration plate 110 cannot fully and effectively control the gesture of the sealing nail, a small amount of sealing nails conveyed by the vibration plate 110 and the nail separating device 120 are in a material reversing gesture, and the sealing nails are not beneficial to sealing the lithium battery in the material reversing gesture.

Referring to fig. 12, fig. 12 is a schematic structural view of a related art seal nail. The seal nail includes a main body 21 and an insertion portion 22 protruding from the main body 21, and the outer diameter of the main body 21 is larger than that of the insertion portion 22. The plugging portion 22 of the sealing nail faces downwards, and the main body portion 21 is in a positive material posture when facing upwards, so that sealing of the lithium battery is facilitated under the positive material posture. The insertion part 22 of the sealing nail faces upwards, and the main body part 21 is in a material-reversing posture when facing downwards.

In order to process the reverse material, the feeding device 130 is further provided with a reverse material processing assembly, and the reverse material processing assembly is used for sorting sealing nails in a reverse material posture on the receiving member 132, so that only sealing nails in a positive material posture are reserved on the receiving member 132 for clamping by the dowel mechanism 400.

The structure of the receiving hole 1321 of the receiving member 132 can be designed according to the specific structure of the sealing nail, so that the material-returning processing assembly can correctly identify and sort out the sealing nail in the material-returning posture. Illustratively, in one embodiment, the receiving bore 1321 is configured such that: the plug 22 of the sealing nail in the normal material posture is positioned in the receiving hole 1321, and the plug 22 of the sealing nail in the reverse material posture is positioned outside the receiving hole 1321. By detecting the position of the insertion portion 22, it can be determined whether the seal nail accommodated in the receiving hole 1321 is in the normal material posture or the reverse material posture.

Illustratively, the receiving bore 1321 includes a first sub-receiving bore 1321a and a second sub-receiving bore 1321b in communication with the first sub-receiving bore 1321a, the first sub-receiving bore 1321a being adapted to the body portion 21 and the second sub-receiving bore 1321b being adapted to the plug portion 22. When the sealing nail is in the positive material posture, the plug-in part 22 is positioned in the second sub-receiving hole 1321b, and the main body part 21 is positioned in the first sub-receiving hole 1321 a; when the seal nail is in the material-reversing posture, the plug-in portion 22 is located outside the receiving hole 1321, and part of the main body portion 21 is located inside the first sub-receiving hole 1321 a.

Optionally, to achieve automatic sorting of the seal staples in the reject pose, in one embodiment, please continue with reference to fig. 11, the reject handling assembly includes a third support plate 133 and a fourth drive 134.

The third supporting plate 133 is communicated with the feeding pipe 131 and is opposite to the receiving piece 132, and a relative distance between the third supporting plate 133 and the receiving piece 132 is greater than the first length and less than the second length. The fourth driving piece 134 is connected with the third supporting plate 133, the fourth driving piece 134 is used for driving the third supporting plate 133 to be close to the receiving piece 132 so that the sealing nails conveyed by the feeding pipe 131 fall into the receiving hole 1321, and the fourth driving piece 134 is also used for driving the third supporting plate 133 to be far away from the receiving piece 132 so that the third supporting plate 133 pushes the sealing nails in the material reflecting posture away from the receiving hole 1321.

The third supporting plate 133 may be provided with a fourth through hole penetrating through the thickness direction of the third supporting plate 133, and the feeding pipe 131 is communicated with the third supporting plate 133, or a conveying channel of the feeding pipe 131 is communicated with the fourth through hole, or the feeding pipe 131 is directly inserted into the fourth through hole.

Specifically, in most cases, in the feeding process, the sealing nail falling into the receiving hole 1321 takes a positive feeding posture, the plugging portion 22 of the sealing nail is fully inserted into the second sub receiving hole 1321b downward, and the portion of the main body 21 is inserted into the first sub receiving hole 1321a, and at this time, the length of the portion of the sealing nail exposed out of the receiving hole 1321 is as follows: the length of the main body 21 minus the depth of the first receiving sub-hole 1321a is the first length, and since the relative distance H from the third support plate 133 to the receiving surface is greater than the first length, a gap exists between the bottom end surface of the third support plate 133 and the sealing nail at this time, and when the fourth driving member 134 drives the third support plate 133 to move back to the initial position, the third support plate 133 does not interfere with the sealing nail, and the sealing nail is stably received in the receiving hole 1321.

However, in a few cases, please refer to fig. 13 and 14, fig. 13 is a cross-sectional view of a feeding device receiving a reverse feeding posture seal nail according to an embodiment of the present application, and fig. 14 is a partial anti-enlargement view at a in fig. 13. The sealing nail dropped into the receiving hole 1321 takes a material-reversing posture, at this time, the insertion portion 22 of the sealing nail faces upward without being inserted into the second sub receiving hole 1321b, and the portion of the main body portion 21 is inserted into the first sub receiving hole 1321a, at this time, the length of the portion of the sealing nail exposed out of the receiving hole 1321 is: the length of the main body 21 minus the depth of the first sub-receiving hole 1321a and plus the length of the plugging portion 22 is the first length plus the length of the plugging portion 22, that is, the second length, and since the relative distance H from the third support plate 133 to the receiving surface is smaller than the second length, the sealing nail is still partially located in the through hole of the third support plate 133 at this time, and then, in the process of the fourth driving member 134 driving the third support plate 133 to move back to the initial position, the third support plate 133 will interfere with and collide with the sealing nail, so as to push the sealing nail down and separate from the receiving hole 1321.

That is, according to the difference in height of the seal nail exposing the receiving hole 1321 in the normal material posture and the reverse material posture, by setting the relative distance between the third support plate 133 and the receiving surface, the seal nail in the reverse material posture can be pushed down and dropped down when the third support plate 133 returns to the initial position, the seal nail in the normal material posture is not affected, and the recognition and sorting functions of the reverse material of the seal nail are realized. Through the arrangement, the embodiment realizes that the feeding device 130 automatically processes the sealing nails in the material reversing posture, manual intervention is not needed, shutdown is not needed, and the feeding efficiency can be improved.
