All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a printing apparatus according to a first embodiment of the present disclosure. The printing apparatus 10 includes a sheet severing mechanism 11, a conveying mechanism 12, a leveling mechanism 13, and a printing mechanism 14.

The sheet severing mechanism 11 is used for severing battery sheets to be processed into groups of small sheets, the conveying mechanism 12 is arranged at the downstream of the sheet severing mechanism 11 and used for conveying the groups of small sheets severed by the sheet severing mechanism 11 to the transfer station, the correcting mechanism 13 is arranged at the downstream of the conveying mechanism 12 and used for extracting the groups of small sheets conveyed by the conveying mechanism 12 from the transfer station and adjusting the relative positions of the groups of small sheets to enable the groups of small sheets to be parallel and aligned, and the printing mechanism 14 is arranged at the downstream of the correcting mechanism 13 and used for coating conductive adhesive on the surfaces of the groups of small sheets in an aligned state after being processed by the correcting mechanism 13.

The "grouped small pieces" described in the present application are specifically a plurality of small pieces obtained by breaking one battery piece.

In this embodiment, the sheet severing mechanism 11 is disposed at the front end of the production line, the whole battery sheet is first severed to obtain a group of small sheets, and then the group of small sheets are coated with the conductive adhesive, so that even when the sheet severing mechanism 11 fails, the undamaged small sheets can be collected for subsequent use. The situation that the small pieces which fail to be broken off can not be reused after the conductive adhesive is coated on the small pieces is avoided. Therefore, the resource utilization rate of the battery piece can be effectively improved, and resource waste is avoided.

According to the above description, the whole battery piece that is not coated with the conductive adhesive is firstly subjected to the piece breaking operation to obtain the grouped small pieces, and then the grouped small pieces are coated with the conductive adhesive, so that even if the piece breaking fails, the undamaged small pieces can be collected to be reserved for subsequent use, the piece breaking after the conductive adhesive is coated is avoided, after the piece breaking fails, the whole group of small pieces cannot be subjected to secondary utilization, the resource utilization rate of the battery piece is effectively improved, and the resource waste is avoided.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a printing apparatus according to a second embodiment of the present application. The printing apparatus 20 includes a sheet severing mechanism 21 for severing the battery sheets to be processed into groups of small pieces 30, a conveying mechanism 22 disposed downstream of the sheet severing mechanism 21 to convey the groups of small pieces 30 severed by the sheet severing mechanism 21 to a transfer station 2242, a leveling mechanism 23 disposed downstream of the conveying mechanism 22 to extract the groups of small pieces 30 transferred by the conveying mechanism 22 from the transfer station 2242 and adjust the relative positions of the groups of small pieces 30 so that the groups of small pieces 30 are parallel and aligned, and a printing mechanism 24 disposed downstream of the leveling mechanism 23 to coat the surfaces of the groups of small pieces 30 in an aligned state after being processed by the leveling mechanism 23 with a conductive paste.

Referring to fig. 3, fig. 3 is a schematic side view of a structure of a transfer mechanism of a printing apparatus provided in the present application. The conveying mechanism 22 includes a first driving wheel 221, a first driven wheel 222, a first driving member 223 and a first conveying belt 224, wherein the first driving wheel 221 and the first driven wheel 222 are correspondingly disposed, the first driving member 223 is connected to the first driving wheel 221 to control the first driving wheel 221 to rotate, the first conveying belt 224 is sleeved on the first driving wheel 221 and the first driven wheel 222, and a surface of the first conveying belt 224 is used for placing the group of small pieces 30 generated by the piece breaking mechanism 21.

In this embodiment, when the printing apparatus 20 is in the operating state, the first driving member 223 is in the operating state, and the first driving wheel 221 is controlled to rotate, because the first driving wheel 221 and the first driven wheel 222 are covered by the first conveyor belt 224, the first driven wheel 222 starts to rotate and the first conveyor belt 224 starts to move under the action of friction force, so as to transport the group of small pieces 30 on the surface of the first conveyor belt 224.

At this time, the transit station 2242 is located on the first conveyor belt 224 along the moving direction of the first conveyor belt 22, and the grouped small pieces 30 are moved to the transit station 2242 by being carried by the first conveyor belt 224; upon reaching the intermediate station 2242, the first drive member 223 is stopped so that the group of tablets 30 remains at the intermediate station 2242, and subsequently the correcting mechanism 23 extracts the group of tablets 30 from the intermediate station 2242.

In other embodiments, the transfer mechanism 22 may be a plurality of conveyor rollers linked to each other and disposed toward the relay station 2242, or a transfer platform driven by a module, as long as it can transfer the grouped small pieces 30 to the relay station 2242, and the present application is not limited thereto.

Further, the conveying mechanism 22 further includes a quality detecting member 225, and a detecting end of the quality detecting member 225 faces a conveying surface of the conveying mechanism 22 for receiving the small pieces. As the group of dies 30 is transported to the transfer station 2242 via the transfer mechanism 22, the quality detector 225 is able to detect whether the group of dies 30 on the surface of the first conveyor belt 224 is acceptable.

In this implementation scenario, quality detector 225 is preferably located upstream of transfer station 2242. Specifically, when the group of small pieces 30 arrives at the relay station 2242, the quality detector 225 detects each small piece, transmits information to the control system, and the control system determines whether the group of small pieces is acceptable. If at least one unqualified small piece exists in the group of small pieces 30, the small pieces 30 forming the group are unqualified products; at this point, as the group of chips 30 is transferred to the transfer station 2242, the transfer mechanism 22 continues to operate to remove the rejected product. If all the small pieces in the group of small pieces 30 are qualified products, the small pieces 30 forming the group are qualified products; at this time, when the group of chips 30 is transferred to the relay station 2242, the transfer mechanism 22 is stopped, so that the alignment mechanism 23 can take out the chips.

The quality detecting element 225 may be a CCD camera, and can photograph the small pieces, so that the control system can compare the small pieces in the photograph with the preset qualified small pieces to determine whether the small pieces are qualified.

Further, the transport mechanism 22 also includes a waste collector 226. The scrap collector 226 is disposed upstream or downstream of the staging station 2242 in the direction of travel of the conveyor 22 for collecting rejected groups of chips 30.

In this implementation, the waste collection element 226 may be a waste bin disposed at the discharge end of the transport mechanism 22. If the group of chips 30 is an unqualified product, when the group of chips 30 is transferred to the transfer station 2242, the transfer mechanism 22 continues to work to directly send the group of chips 30 into the waste bin, and the qualified chips are manually removed and selected for secondary use.

In other implementations, waste collection 226 may be a handling device that can remove the rejected group of chips 30 on transport mechanism 22. At this time, the handling device may be disposed upstream of the transfer station 2242, and the unqualified grouped small pieces 30 are taken away before the unqualified grouped small pieces 30 reach the transfer station 2242; a handling device may also be provided downstream of the transfer station 2242 to remove the rejected grouped pieces 30 after the rejected grouped pieces 30 leave the transfer station 2242. The carrying device can be a mechanical arm, a sucker and other mechanisms, and the application is not limited.

The alignment mechanism 23 includes an alignment assembly 231 and an extraction assembly 232. The alignment assembly 231 is used to pick up the groups of chips 30 transferred by the transfer mechanism 22 and to perform position adjustment of each chip. The pick-up assembly 232 is coupled to the alignment assembly 231 to drive the alignment assembly 231 toward and away from the staging station 2242 or the printing mechanism 24 and to drive the alignment assembly 231 back and forth between the transport mechanism 22 and the printing mechanism 24 to effect pick-up, release, or transfer of the die by the alignment assembly 231.

In one embodiment, the alignment assembly 231 is positioned above the transport mechanism 22 and the printing mechanism 24 to facilitate the alignment assembly 231 to pick up, release, or transfer the die. The picking assembly 232 includes a first drive assembly 2321 and a second drive assembly 2322, and the first drive assembly 2321 is coupled to and drives the registration assembly 231 to move in a vertical direction toward, or away from, the staging station 2242 or the printing mechanism 24 to facilitate picking of the patches from the staging station 2242 by the registration assembly 231 or releasing the patches to the printing mechanism 24 by the registration assembly 231. The second driving assembly 2322 is connected to and drives the alignment assembly 231 to move in the horizontal direction back and forth between the transport mechanism 22 and the printing mechanism 24 to effect the transfer of the die. Specifically, the alignment component 231 may be disposed at the output end of the first driving component 2321, and the first driving component 2321 may be disposed at the output end of the second driving component 2322; alternatively, the alignment component 231 may be disposed at the output of the second driving component 2322, and the second driving component 2322 may be disposed at the output of the first driving component 2321. The first driving assembly 2321 may be a linear module disposed along a vertical direction; the second driving assembly 2322 may be a linear module disposed in a horizontal direction.

In another embodiment, the picking assembly 232 may be a robot, and the three-dimensional movement of the alignment assembly 231 can be achieved by the robot, so as to meet the requirements of alignment and transfer of the small pieces.

It should be noted that, in the process of the alignment mechanism 23 extracting the group of small pieces 30 on the conveying mechanism 22 and transferring the group of small pieces 30 to the printing mechanism 24, the alignment mechanism 23 may extract all the small pieces of the group of small pieces 30 at a time or extract the small pieces in several times until the group of small pieces 30 is placed on the printing mechanism 24.

Referring to fig. 4, fig. 4 is a schematic side view of a structure of a calibration assembly of the printing apparatus provided in the present application. The alignment assembly 231 includes a plurality of pick-up members 2311 and a plurality of alignment members 2312, the pick-up members 2311 correspond to the alignment members 2312 one-to-one, the pick-up members 2311 are provided at the output end of the alignment members 2312, the pick-up members 2311 are used for picking up the group of chips 30, the group of chips 30 generally includes a plurality of chips, at this time, the plurality of pick-up members 2311 are respectively used for picking up one chip, and after the chips are picked up, the alignment members 2312 drive the pick-up members 2311 to move until the chips are parallel and aligned. It should be noted that the grouped patches 30 are typically a plurality of rectangular patches with consistent specifications. During deviation correction, the small pieces are adjusted to be parallel and aligned, namely, the edges of the small pieces are correspondingly parallel, and the small pieces are aligned at the two ends in the lamination direction. The "lamination direction" is the extending direction of the small piece, specifically, the up-down direction shown in fig. 2.

Specifically, when the alignment assembly 231 approaches the transit station 2242, the pick-up assembly 232 drives the alignment assembly 231 to descend to each pick-up member 2311 to pick up the corresponding tab; subsequently, the pick-up assembly 232 drives the alignment assembly 231 up, so that the chips are detached from the transport mechanism 22, and drives the alignment assembly 231 to move toward the printing mechanism 24; at the same time, each of the regulating members 2312 drives the corresponding extracting member 2311 to move, so that each of the small pieces 30 extracted by the extracting member 2311 is parallel and aligned; after the leveling assembly 231 approaches the printing mechanism 24, the picking assembly 232 drives the leveling assembly 231 down to the picking member 2311 to release the picked set of patches 30 into the printing mechanism 24.

In the present implementation scenario, to enable adjustment of the group of tabs 30 extracted by the extractor 2311, the corrector 2312 drives the extractor 2311 to move in the x, y, θ, etc. directions. The X direction is an abscissa direction in the horizontal plane, the Y direction is an ordinate direction in the horizontal plane, and θ is a direction in the XY plane in which the workpiece can rotate. The extracting member 2311 may be a sucking disc or a clamp or other components for extraction, and the correcting member 2312 may be a deviation correcting module.

Furthermore, the deviation rectifying module comprises an X-direction driving assembly, a Y-direction driving assembly and a theta-direction driving assembly. The X-direction drive assembly is coupled to and drives the picker 2311 to move in the X-direction, the Y-direction drive assembly is coupled to and drives the picker 2311 to move in the Y-direction, and the θ -direction drive assembly is coupled to and drives the picker 2311 to rotate in a horizontal plane defined by XY. The position of each small piece in the XY plane can be adjusted through the X-direction driving assembly and the Y-direction driving assembly, so that each small piece reaches a required position and is aligned in the Y direction (namely the stacking direction); the small pieces can be adjusted to be correspondingly parallel on each side in an XY plane through the theta direction driving assembly. Specifically, the deviation rectification module is a prior art and is not described herein again.

Further, the alignment mechanism 23 further includes an alignment detector 233 whose detection end faces the conveying surface of the conveying mechanism 22 for receiving the chips, and the alignment detector 233 can detect the positions of the chips 30 in the group when the chips are conveyed to the relay station 2242 via the conveying mechanism 22, so that the alignment detector 2312 drives the extractor 2311 to adjust the positions of the chips 30 in the group.

In this embodiment, the alignment detector 233 is preferably disposed near the transfer station 2242. Specifically, before the group of chips 30 reaches the transfer station 2242 and is extracted by the alignment unit 231, the alignment detector 233 detects each chip and transmits information to the control system, the control system determines the positions of the chips, and the control system controls the extraction unit 232 to drive the alignment unit 231 to the positions to accurately extract the chips. The control system then controls the alignment member 2312 to correct the relative position of the tabs.

The alignment detector 233 may be a CCD camera, and can photograph the small piece, so that the control system can obtain the position information of the small piece.

In other implementations, the alignment detector 233 and the quality detector 225 are the same component that detects both the position of each of the sets of dies 30 extracted by the extractor 2311 and the failure of the sets of dies 30 on the surface of the first conveyor belt 224.

Further, when the number of the small pieces in the grouped small pieces 30 is greater than 2, the alignment component 231 may select a small piece near the middle position among the plurality of small pieces as the reference piece in the alignment process of the small pieces, for example, when the number of the small pieces is 3, the middle small piece is used as the reference piece. After the alignment detector 233 detects the group of the small pieces 30, the control system obtains the position information of each small piece, and controls the alignment device 2312 to adjust the other small pieces based on the position state of the reference device, so that the other small pieces are correspondingly parallel to the sides of the reference device and aligned with the two ends in the stacking direction, thereby improving the correction efficiency of the alignment assembly 231 for the small pieces. In this embodiment, the extracting member 2311 corresponding to the reference member may not be provided with the regulating member 2312, thereby reducing the cost.

The printing mechanism 24 includes a material receiving assembly 241, a printing assembly 242, and a turntable 243, wherein the material receiving assembly 241 is used for placing the grouped small pieces 30 which are regulated by the regulating mechanism 23, the printing assembly 242 is used for coating the conductive adhesive on the surfaces of the grouped small pieces 30, and the material receiving assembly 241 is arranged at intervals along the circumferential direction of the turntable 243. The turntable 243 is driven by a driving member to rotate cyclically to move the received group of small pieces 30 between the receiving station 2431 and the printing station 2432. The receiving station 2431 is configured to receive the aligned group of small pieces 30 deposited by the alignment mechanism 23, and the printing station 2432 is configured to apply the conductive adhesive to the group of small pieces 30 by the printing assembly 242.

Specifically, when an empty receiving assembly 241 is located at the receiving station 2431, the rotating disc 243 stops rotating, the alignment mechanism 23 puts down the aligned group of small pieces 30 at the receiving station 2431, and the receiving assembly 241 receives the group of small pieces 30; the turntable 243 rotates continuously to rotate the material receiving assembly 241 with the small pieces and the group of small pieces 30 received by the material receiving assembly 241 to the printing station 2432, and the printing assembly 242 coats the group of small pieces 30 located at the printing station 2432 with the conductive adhesive; further, in order to ensure the processing efficiency, when one material receiving assembly 241 is located at the material receiving station 2431 and receives and takes a small piece, another material receiving assembly 241 is located at the printing station 2432, and the small piece is printed with conductive adhesive, that is, when the turntable 243 rotates once, just one material receiving assembly 241 is located at the working station, so that the continuous operation of the equipment is ensured. In this embodiment, the rotating plate 243 is driven by a revolution driving member (not shown) to rotate around its central axis, and the revolution driving member may be a motor or other driving device.

In an implementation scenario, the material receiving surface of the material receiving assembly 241 for receiving the small piece is provided with an adsorption hole, and the adsorption hole is communicated with an external air extraction device, so that after the material receiving assembly 241 receives the small piece, the small piece can be absorbed by the adsorption hole, and the small piece is prevented from deviating from an original station in the rotating process of the turntable 243.

Further, when the printing module 242 brushes the group of small pieces 30 with glue, if particles such as dust are present on the plane where the receiving module 241 receives the group of small pieces 30, that is, on the surface of the second conveyor 2414, at least some of the group of small pieces 30 will be uneven, and when the printing module 242 coats the conductive glue, hidden cracks of the small pieces will be caused. Therefore, in an embodiment, the receiving surface of the receiving assembly 241 can be cleaned manually at regular time. For example, the material receiving surface can be paved with table surface paper and replaced by manpower regularly.

In another implementation scenario, please refer to fig. 5 in combination, fig. 5 is a schematic side view of a structure of a material receiving assembly in a printing apparatus provided by the present application, in which the material receiving assembly 241 includes a second driving wheel 2411, a second driven wheel 2412, a second driving member 2413, a second conveyor belt 2414 and a vacuum cavity 2415, the second driving wheel 2411 and the second driven wheel 2412 are disposed correspondingly, the second driving member 2413 is connected to the second driving wheel 2411 to drive the second driving wheel 2411 to rotate, the second conveyor belt 2414 is sleeved on the second driving wheel 2411 and the second driven wheel 2412, a plurality of air holes 24141 are opened on the second conveyor belt 2414, and the surface of the second conveyor belt 2414 is used for placing the group of small pieces 30. The vacuum cavities 2415 are positioned in the middle of the second conveyor belt 2414 to adhere the groups of chips 30 on the second conveyor belt 2414 to the surface of the second conveyor belt 2414. This effectively prevents the group of chips 30 from being displaced during rotation of the turntable 243.

In this implementation scenario, before the receiving assembly 241 receives a new group of chips 30, the second driving element 2413 drives the first driving wheel 2411 to rotate, under the action of friction, the second driven wheel 2412 is driven to rotate, the second conveying belt 2414 is driven to rotate, the back surface of the second conveying belt 2414 originally on the back surface is switched to the front surface, when the back surface of the second conveying belt 2414 originally on the back surface is switched to the front surface, the second conveying belt 2414 originally on the front surface is switched to the back surface, if particles such as dust exist on the surface of the second conveying belt 2414 originally on the front surface, the particles are brought to the back surface together, so as to leave the adsorption area of the vacuum cavity 2415, the particles will fall off, so that the front surface of the first conveying belt 2414, that is, there are no particles on the receiving surface of the receiving assembly 241, and the product yield is effectively improved. The second conveyor belt 2414 may be roll paper.

Printing assembly 242 includes printing plate 2421, brush blade 2422 and printing drive part 2423, wherein, printing plate 2421 is provided with a hollowed hole, printing drive part 2423 is connected and drives printing plate 2421 to move, so that printing plate 2421 abuts against group of small pieces 30 transferred to printing station 2432, brush blade 2422 scrapes conductive adhesive across printing plate 2421, and the conductive adhesive flows out through the hollowed hole and is coated on group of small pieces 30 at printing station 2432.

Further, the printing mechanism 24 further includes a blanking assembly 244, the blanking assembly 244 being disposed downstream of the printing assembly 242 in the rotation direction of the turntable 243 for transferring the group of small pieces 30 coated with the conductive paste. Correspondingly, when the turntable 243 is driven by the driving member to rotate circularly, the group of small pieces 30 which operate on the turntable leave the printing station 2432 and then enter the blanking station 2433, and the blanking assembly 244 is arranged at the blanking station 2433 and can transfer out the group of small pieces 30 which are coated with the conductive adhesive, so that the material receiving assembly 241 is empty and ready to receive a group of small pieces to be brushed.

In this implementation scenario, please refer to fig. 6 in combination, and fig. 6 is a schematic structural diagram of a blanking assembly of the printing apparatus provided in the present application. The blanking assembly 244 is similar to the extraction assembly 232. The blanking assembly 244 comprises a third driving assembly 2441, a fourth driving assembly 2442 and a blanking member 2443, wherein the blanking member 2443 is used for extracting small pieces; the third driving assembly 2441 is arranged along the vertical direction and is connected with and drives the blanking member 2443 to move in the vertical direction so as to be close to or far away from the blanking station 2433 and achieve the picking of small pieces; the fourth driving assembly 2442 is disposed in a horizontal direction, and is connected to and drives the discharging member 2443 to move in the horizontal direction.

Further, the printing mechanism 24 further includes a printing detector 245, and the printing detector 245 is located downstream of the printing assembly 242 in the present implementation scenario to detect the group of small pieces 30 coated with the conductive adhesive and send the detection result to the control system, so that the control system can determine whether a problem piece is generated during printing, and the next process is facilitated. Specifically, as the carousel 243 is driven to rotate cyclically by the drive member, the group of dies 30 that it is moving away from the printing station 2432 enters the inspection station 2434, and the inspection end of the printed inspection member 245 faces the inspection station 2434 to inspect the group of dies 30 at the inspection station 2434. At the end of the test, the turntable 243 continues to rotate so that the group of chips 30 reaches the blanking station 2433 where the group of chips 30 is removed by the blanking assembly 244. The group of chips 30 that the control system determines as non-defective are sent to a downstream facility (not shown), and the defective group of chips 30 can be handled by a defective chip collecting facility (not shown).

In the present implementation scenario, when the material receiving assembly 241 receiving the group of small pieces 30 passes through each station (including the material receiving station 2431, the printing station 2432, the blanking station 2433, and the detection station 2434), the rotation of the turntable 243 is suspended, so that the alignment mechanism 23, the printing assembly 242, the blanking assembly 244, and the printing detection member 245 corresponding to the material receiving station 2431, the printing station 2432, the blanking station 2433, and the detection station 2434, respectively, can successfully complete the work task.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
