Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.

Batteries often include one or more cell assemblies that, due to their own nature, tend to expand after a certain number of cycles of charge, thus requiring an adhesive process to be applied to the cell assembly prior to completion of the assembly process.

Because of the different composition of the active materials used in the cell assembly, the volume of expansion of the cell assembly is different after a certain number of cycles of charge (e.g., 1000 cycles of charge). The partial cell component which adopts lithium iron phosphate and other materials as active substances is relatively small in expansion volume due to the fact that the material properties of the active substances are more stable, and a whole piece of sheet materials are often adopted to be attached to the side face of the cell component. The other part of the battery cell component which adopts the materials such as the ternary polymer and the like as the active substances has relatively large expansion volume, and the adhesive tape is often stuck on the side surface of the battery cell component, so that a larger space is reserved.

The inventors noted that both the strip and the sheet include a middle glue, top side glue and bottom side glue on both sides of the middle glue. The top side gummed paper and the bottom side gummed paper have the functions of preventing unnecessary adhesion between double-sided gummed objects and other objects, and the top side gummed paper and the bottom side gummed paper need to be torn off before the double-sided gummed objects are adhered to the battery cell assembly; the adhesive tape actually exists in a whole sheet form, so that the adhesive tape is used for an adhesive process, the adhesive tape needs to be split in advance, the adhesive process is carried out on the sheet adhesive, the adhesive tape is not split, the difference of the adhesive tape on the top side and the adhesive tape on the bottom side is caused by the difference of process steps, and a manufacturer needs to prepare two sets of independent equipment or select a manual assembly mode for a certain adhesive process; thus, the working load of the gluing process in the assembly process of the battery is large, and the working efficiency is low.

In order to alleviate the problem of low working efficiency in the process of using the sheet glue or the adhesive tape to carry out the adhesive bonding, the inventor researches and discovers that different treatments can be carried out on the adhesive tape and the sheet glue, the bottom side adhesive paper is uniformly torn off through the first paper tearing unit, and the top side adhesive paper is respectively torn off through the second paper tearing unit; therefore, the material is subjected to glue separation, the top side gummed paper and the bottom side gummed paper are automatically torn off, the rubberizing process is completed, the whole process does not need manpower to participate in splitting the adhesive tape, and the manpower to participate in tearing off the top side gummed paper, so that the automation degree is high, the compatibility is good, the working efficiency is high, and a large amount of labor cost and equipment cost are saved.

The battery cell rubberizing machine disclosed by the embodiment of the application can be used for assembling a primary battery and a secondary battery, but is not limited to the battery cell rubberizing machine. The embodiment of the application provides a battery production line using the battery cell rubberizing machine, which is beneficial to alleviating the problem of low working efficiency in the process of gluing.

Fig. 23 is an exploded view of an assembled battery cell 1000 according to some embodiments of the present application. The battery cell 1000 refers to the smallest unit constituting the battery. Cell 1000 includes end cap 910, housing 920, cell assembly 930, and other functional components.

The end cap 910 refers to a member that is covered at the opening of the case 920 to isolate the internal environment of the battery cell 1000 from the external environment. Without limitation, the shape of the end cap 910 may be adapted to the shape of the housing 920 to fit the housing 920. Optionally, the end cover 910 may be made of a material (such as an aluminum alloy) with a certain hardness and strength, so that the end cover 910 is not easy to deform when being extruded and collided, so that the battery cell 1000 can have a higher structural strength, and the safety performance can be improved. The end cap 910 may be provided with a functional part such as an electrode terminal or the like. The electrode terminals may be used to electrically connect with the battery cell assembly 930 for outputting or inputting electric power of the battery cell 1000. In some embodiments, a pressure relief mechanism may also be provided on end cap 910 for relieving the internal pressure when the internal pressure or temperature of cell 1000 reaches a threshold.

By way of example, the insulation may be plastic, rubber, or the like.

Housing 920 is an assembly for mating with end cap 910 to form the internal environment of cell 1000, where the internal environment formed may be used to house cell assembly 930, electrolyte, and other components. The case 920 and the end cap 910 may be separate components, and an opening may be provided in the case 920, and the interior of the battery cell 1000 may be formed by covering the opening with the end cap 910 at the opening. However, the end cap 910 and the housing 920 may be integrated, specifically, the end cap 910 and the housing 920 may form a common connection surface before other components are put into the housing, and when the interior of the housing 920 needs to be sealed, the end cap 910 is further covered with the housing 920. The housing 920 may be of various shapes and sizes, such as rectangular parallelepiped, cylindrical, hexagonal prism, etc. In particular, the shape of the housing 920 may be determined according to the specific shape and size of the cell assembly 930. The material of the housing 920 may be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., which is not particularly limited in the embodiment of the present application.

The cell assembly 930 is formed mainly of a positive electrode sheet and a negative electrode sheet wound or stacked, and a separator is generally provided between the positive electrode sheet and the negative electrode sheet.

During charge and discharge of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tab is connected with the electrode terminal to form a current loop.

A whole piece of adhesive or glue strip is adhered between the battery cell assembly 930 and between the battery cell assembly 930 and the housing 920, so as to reserve a space.

The first aspect of the application provides a battery cell rubberizing machine.

Referring to fig. 1 to 22, the cell paste machine includes: the device comprises a feeding unit 100, a glue distributing unit 200, a glue applying unit 300, a first paper tearing unit 400 and a second paper tearing unit 500.

The feeding unit 100 can grasp the material 900 and transfer the material to the glue distributing unit 200 for glue distributing treatment. The material 900 can be a whole piece of sheet glue or a whole piece of adhesive tape; the glue separation treatment is configured as follows: the material is whole piece of piece glue, and the piece glue is temporarily stored; the material is a whole adhesive tape, and the whole adhesive tape is split into separate adhesive tapes.

The rubberizing unit 300 is used for rubberizing the materials subjected to rubberizing treatment; the first paper tearing unit 400 is used for tearing off the bottom gummed paper of the material 900; the glue dispensing unit 200 is capable of adsorbing the bottom side of the material 900 for the second paper tearing unit 500 to tear off the top side glue of the material.

Specifically, the feeding unit 100 can grasp the material 900 to be processed and transfer the material to the glue distributing unit 200 for glue distributing processing; according to the fact that the material 900 is whole piece of glue or whole piece of glue strip, the cell glue applicator can automatically select to switch or manually switch the content of glue separation treatment; namely, when the material is a whole piece of sheet rubber, the glue separating unit 200 temporarily stores the whole piece of glue, the subsequent rubberizing unit 300 is convenient to directly take the piece of rubberizing from the rubberizing unit 200 and rubberize with the electric core component 930; when the material is the whole adhesive tape, the whole adhesive tape is split into the single adhesive tape by the adhesive tape splitting unit 200, so that the follow-up adhesive tape sticking unit 300 can conveniently take the split single adhesive tape out of the adhesive tape splitting unit 200, and the single adhesive tape and the battery cell component 930 are stuck.

It should be noted that, the material 900 to be treated is an adhesive tape or a sheet adhesive, and the whole material is sheet-shaped, including a middle adhesive, and a top adhesive paper and a bottom adhesive paper respectively located at two sides of the middle adhesive. The top side gummed paper and the bottom side gummed paper can outwards extend to form the grabbing portion beyond the range of the gummed material, for example, the grabbing portion can be formed into a short strip-shaped ear, and therefore equipment or manual work can be facilitated, and the gummed paper can be torn down through clamping the grabbing portion. Before the adhesive tape is split, the adhesive substance in the adhesive tape is divided into a strip-shaped structure in advance and is adhered to each other to form a sheet-shaped adhesive tape, and the adhesive force can be overcome under the action of external force to form an independent adhesive tape; for the sheet glue, the glue substance is in a whole sheet shape. In the following description of the embodiments, for convenience of understanding, the rubberizing process is directly described by using a glue strip or a glue sheet, and if the material 900 is present, the material 900 may be any glue strip or glue sheet without notice.

In the process that the material 900 to be processed is grabbed by the feeding unit 100 and transferred to the glue distributing unit 200, the feeding unit 100 can adsorb the top side of the material 900, and at the moment, the bottom side glue paper at the bottom of the material 900 is exposed, so that the first paper tearing unit 400 can conveniently tear the bottom side glue paper of the material 900.

The piece gum is temporarily stored on the gum separating unit 200, and the gum separating unit 200 can adsorb the bottom side of the piece gum, so that the top side gummed paper of the piece gum is conveniently exposed, and further the second paper tearing unit 500 tears the top side gummed paper of the material 900.

The whole adhesive tape is stored on the adhesive separating unit 200, and the adhesive separating unit 200 can adsorb the bottom side of the whole adhesive tape, so that the top side adhesive paper of the adhesive tape is conveniently exposed, and further the second paper tearing unit 500 can tear off the top side adhesive paper of the adhesive tape, so that the middle adhesive substance is exposed; the whole piece of glue is split into separate glue strips by the glue splitting unit 200, the subsequent glue applying unit 300 takes the split separate glue strips from the glue splitting unit 200 and applies the separate glue strips to the cell assembly 930.

Therefore, the battery core rubberizing machine provided by the embodiment of the application can automatically finish the rubberizing treatment of the material 900, and automatically tear off the top side gummed paper and the bottom side gummed paper, so that the rubberizing process is finished, and the whole process is high in automation degree and good in compatibility, so that the working efficiency is high, and a large amount of labor cost and equipment cost are saved as the adhesive tape is not required to be split and the labor is not required to be torn off.

It should be noted that, referring to the orientation shown in fig. 1, the top side and the bottom side of the material 900 according to the embodiments of the present application are aligned with the orientation shown in fig. 1, where the upper side of the material 900 is the top side and the lower side of the material 900 is the bottom side.

In some embodiments, referring to fig. 1-4 and 22, the die bonder includes a table 700, which table 700 may be constructed of a rigid frame for holding the various components. The rubberizing unit 300, the feeding unit 100 and the glue distributing unit 200 are all arranged on the workbench 700.

The feeding unit 100 is positioned at one side of the glue distributing unit 200, so that the feeding unit 100 can conveniently transfer the grabbed material 900 to the glue distributing unit 200; the rubberizing unit 300 may be disposed at the other side of the rubberizing unit 200 to prevent interference with the feeding unit 100 during the material transporting and discharging process.

The first paper tearing unit 400 is fixed on the workbench 700; thus, the position of the first paper tearing unit 400 is fixed, and the feeding unit 100 adsorbs the top side of the material 900 in the process of transferring the grabbed material 900 to the glue separating unit 200, so that the first paper tearing unit 400 grabs the grabbing part on the bottom side glue paper of the material 900 at a uniform angle, and the failure of tearing the bottom side glue paper is prevented.

In some embodiments, referring to fig. 1 to 5, the first tearing unit 400 includes a first gumming jaw 410, and the first gumming jaw 410 is disposed on a path along which the feeding unit 100 is transferred to the dispensing unit 200.

Specifically, the first gummed paper holding jaw 410 should be disposed between the feeding unit 100 and the gummed unit 200; thus, when the feeding unit 100 grabs the material 900 to be processed and moves towards the glue distributing unit 200, the first glue clamping jaw 410 is located on the path of the feeding unit 100 transferring towards the glue distributing unit 200, so that the feeding unit 100 only needs to stay at the position corresponding to the first glue clamping jaw 410, and can clamp the grabbing part of the bottom glue through the first glue clamping jaw 410, the feeding unit 100 continues to move towards the glue distributing unit 200, and the bottom glue is immediately separated from the bottom side of the glue; at this point, the material 900 has already torn off the bottom side gummed paper; the feeding unit 100 transfers the material 900 with the bottom side gummed paper torn off to the gumming unit 200 for gumming treatment.

In addition, the battery cell rubberizing machine can further comprise a first checking unit 610; the first inspection unit 610 is disposed on a path of the feeding unit 100 from the first paper tearing unit 400 to the glue dispensing unit 200.

The first inspection unit 610 may be a CCD camera, and is in signal connection with the feeding unit 100.

According to different types and sizes of materials 900, the position of the first gummed paper clamping jaw 410 is adjusted, so that the first gummed paper clamping jaw 410 is always positioned on a path of the feeding unit 100 transferring to the gumming unit 200; thereby ensuring that the tearing off of the bottom side gummed paper by the first gummed paper holding jaw 410 is performed stably.

In some embodiments, referring to fig. 1-4, and 22, the second paper tearing unit 500 includes a second gummed paper holding jaw 510; the second gummed paper clamping jaw 510 is arranged on the feeding unit 100.

That is, the second adhesive tape holding jaw 510 moves along with the feeding unit 100, so that the second adhesive tape holding jaw 510 can tear off the top adhesive tape of the whole adhesive tape.

Tearing off of the bottom side gummed paper is completed by the first gummed paper tearing unit 400, and tearing off of the top side gummed paper is completed by the second gummed paper clamping jaw 510, at this time, the whole piece of adhesive tape on the mounting frame 210 only remains the intermediate gummed material; the subsequent glue separating unit is convenient to separate the glue into separate glue strips, namely, the separate glue strips are separated into separate glue strips, the subsequent glue applying unit 300 takes away the separated separate glue strips from the glue separating unit 200, and the separate glue strips and the battery cell assembly 930 are subjected to glue application, so that the glue application process is automatically completed.

The second gummed paper holding jaw 510 moves along with the feeding unit 100, and can tear off the gummed paper on the top side of the sheet glue.

The process of tearing off the top side gummed paper is similar to the adhesive tape, and the feeding unit 100 transfers the sheet adhesive of the torn off bottom side gummed paper to the adhesive separating unit 200 in combination with the orientation shown in fig. 2, the feeding unit 100 does not adsorb the top side of the sheet adhesive any more, and the sheet adhesive is placed on the placing frame 210 of the adhesive separating unit 200; the placing frame 210 can adsorb the bottom side of the sheet glue to realize fixation, the top side gummed paper at the top of the sheet glue is exposed, the second gummed paper clamping jaw 510 on the feeding unit 100 can clamp the grabbing part of the top side gummed paper, and the feeding unit 100 drives the second gummed paper clamping jaw 510 to move in the process of returning from the glue distributing unit 200, so that the top side gummed paper is separated from the top side of the glue.

Thus, the first paper tearing unit 400 is used for tearing off the bottom side gummed paper of the material 900, and the second gummed paper clamping jaw 510 is used for tearing off the top side gummed paper of the material 900; regardless of whether the material 900 is a piece of glue or a piece of adhesive tape, the whole process is high in automation degree and good in compatibility because the labor is not needed any more to participate in tearing off the top side adhesive tape, and the procedures of tearing off the adhesive tape between the piece of glue and the adhesive tape are unified, so that the working efficiency is high, and a large amount of labor cost and equipment cost are saved.

Alternatively, the second gumming jaw 510 can be a pneumatic jaw that is actuated to open or clamp by an external air source.

In addition, the die bonder may include a second inspection unit 620, where the second inspection unit 620 is usually a CCD camera, and the second inspection unit 620 is connected with the feeding unit 100, a deviation correcting device 281 (mentioned below), and signals. The second inspection unit 620 is disposed above the first working position 211 corresponding to the placement frame 210; in this way, whether the posture of the film on the first working position 211 is inclined or not can be detected by the second checking unit 620; it is also possible to detect whether the posture of the whole adhesive tape on the first working position 211 is inclined, whether the top side adhesive paper of the whole adhesive tape is completely torn off, etc. through the second checking unit 620.

In some embodiments, referring to fig. 1-4 and 22, the loading unit 100 may be selected to be a three-axis robot, a four-axis robot, or a five-axis robot, as desired.

One end of the feeding unit 100 is fixed on the table surface of the table 700, and the second gummed paper clamping jaw 510 is arranged on the end 110 of the feeding unit 100, which is far away from the table 700.

The end 110 of the loading unit 100 away from the table 700 has a plurality of third adsorption structures 120 to facilitate gripping the adsorption material 900.

Specifically, the third adsorption structure 120 may be a pore structure. The bottom surface of the end 110 of the feeding unit 100, i.e. the surface of the end 110 for contacting the material 900, is typically provided with a plurality of third adsorption structures 120; the second gumming jaw 510 can be disposed on the bottom surface of the tip 110 or directly on the side of the tip 110.

It can be understood that the material 900 is placed on the glue dispensing unit 200 by the material loading unit 100, and at this time, the vacuum negative pressure in the third adsorption structure 120 is changed to blow air outwards, so that the material 900 can be rapidly transferred from the tail end 110 of the material loading unit 100 to the glue dispensing unit 200, and subsequent operations are convenient.

It should be noted that, although the tearing off of the top side adhesive tape of the adhesive tape can be completed by using the second adhesive tape clamping jaw 510, only 1 piece of adhesive tape is adhered to one battery cell assembly 930; in the process of transferring the sheet glue, the feeding unit 100 needs to tear off the bottom side glue paper through the first paper tearing unit 400, and after the sheet glue is put down, the tearing-off action on the top side glue paper needs to be completed, and then the material 900 to be processed is returned to be grabbed again and transferred to the glue distributing unit 200; the rubberizing unit is only responsible for rubberizing, and the working beat difference of the rubberizing unit and the rubberizing unit is huge, so that larger productivity waste can be caused.

In some embodiments, referring to fig. 1-4 and 22, the second paper tearing unit 500 includes a third glue jaw 520, where the third glue jaw 520 is disposed on the rubberizing unit 300.

That is, the third glue jaw 520 may follow the movement of the rubberizing unit 300, thereby facilitating the second glue jaw 510 to tear off the top side glue of the sheet glue.

Specifically, with reference to the orientations shown in fig. 1 and 2, the feeding unit 100 transfers the sheet glue with the bottom side glue paper torn off to the glue distributing unit 200 for glue distributing treatment, the feeding unit 100 does not adsorb the top side of the sheet glue any more, and the sheet glue is placed on the placement frame 210 of the glue distributing unit 200; at this time, the adhesive tape still has intermediate adhesive and top adhesive paper, temporary storage is carried out by the adhesive separating unit 200, the subsequent adhesive tape pasting unit 300 then takes away the adhesive tape from the adhesive separating unit 200, and pastes the adhesive tape and the battery cell component 930, after the adhesive tape is pasted, the bottom side of the adhesive tape is adhered to the side part of the battery cell component 930, the top adhesive paper on the top of the adhesive tape is exposed, the grabbing part of the top adhesive paper can be clamped by the third adhesive paper clamping jaw 520 on the adhesive tape pasting unit 300, and the adhesive tape pasting unit 300 drives the third adhesive paper clamping jaw 520 to move in the process of returning from the battery cell component 930 to the adhesive separating unit 200, and then the adhesive tape on the top of the adhesive tape is separated from the adhesive tape; thus, the sheet adhesive stuck on the side of the battery cell component 930 only remains the intermediate adhesive; thereby automating the adhesive process for the cell assembly 930.

Thus, the first paper tearing unit 400 is used for tearing off the bottom side gummed paper of the material 900, and the second gummed paper clamping jaw 510 is used for tearing off the top side gummed paper of the whole adhesive tape; the third gummed paper clamping jaw 520 is used for finishing the tearing off of the gummed paper on the top side of the sheet gum, so that the gummed paper tearing off process of the material 900 is finished, the manual labor is not needed to participate in the gummed paper tearing off process in the whole process, the beat consistency of the feeding unit 100 and the rubberizing unit 300 is better, the productivity is fully utilized, the working efficiency is high, and a large amount of labor cost and equipment cost are saved.

Alternatively, the third gumming jaw 520 may be a pneumatic jaw that is actuated to open or clamp by an external air source.

In some embodiments, referring to fig. 1-4, and 22, the rubberizing unit 300 may be selected as a three-axis robot, a four-axis robot, or a five-axis robot, as desired.

One end of the rubberizing unit 300 is disposed on the top of the table 700 and a third gumming jaw 520 is disposed at the end 310 of the rubberizing unit 300 remote from the table 700.

The end 310 of the taping unit 300 remote from the table 700 has a plurality of fourth adsorption structures 320 to facilitate gripping of the adsorption sheet adhesive.

Specifically, the fourth adsorption structure 320 may be a pore structure. The bottom surface of the end 310 of the rubberizing unit 300, i.e. the surface of the end 310 for bonding with the sheet, is typically provided with a plurality of fourth adsorption structures 320; the third glue jaw 520 is arranged on the bottom surface of the end 310 or directly on the side of the end 310.

The rubberizing unit 300 can grasp the material 900 which has undergone the rubberizing treatment from the rubberizing unit 200, and in the process of grasping, appropriate vacuum negative pressure can be generated in the fourth adsorption structure 320, so that the material 900 can be stuck on the tail end 310 of the rubberizing unit 300, and the transfer to the battery core 930 is facilitated.

It should be emphasized that the working process of the first tearing unit 400, the second gumming jaw 510 and the third gumming jaw 520 is as follows:

if the material 900 is a glue strip, when the glue applying unit 300 grabs the glue strip on the glue separating unit 200, the glue strip is already torn off by the first paper tearing unit 400 and the second glue clamping jaw 510, so that the top glue paper and the bottom glue paper are respectively torn off, only the middle glue material remains, the glue material is split into separate glue strips under the action of the glue separating unit 200, and the glue applying unit 300 attaches the separate glue strips to the side of the electric core component 930. If the material 900 is a piece of glue, when the glue applying unit 300 grabs the piece of glue on the glue separating unit 200, the piece of glue is torn off by the first paper tearing unit 400, the remaining middle glue and the top glue are adhered to the side of the battery cell assembly 930 by the glue applying unit 300, and then the top glue is torn off by the third glue clamping jaw 520, and only the remaining middle glue is adhered to the side of the battery cell assembly 930.

It can be appreciated that the rubberizing unit 300 adheres the material 900 to the side of the cell module 930, and at this time, the vacuum negative pressure in the fourth adsorption structure 320 is changed to blow air outwards, so that the material 900 can be rapidly separated from the end 320 of the rubberizing unit 300 and attached to the side of the cell module 930 by means of adhesion.

In some embodiments, referring to fig. 1-4, and fig. 6-22; the glue dispensing unit 200 includes a mounting frame 210 and a glue dispensing device 220.

Wherein, the placement frame 210 has a first working position 211 and a second working position 212; the glue distributing device 220 is movably arranged on the placement frame 210; and is capable of switching back and forth between the first working position 211 and the second working position 212. The glue dispensing device 220 is capable of splitting a complete piece of glue strip located at the first work station 211 into individual glue strips and transferring to the second work station 212.

Specifically, when the material 900 is a piece of glue, the feeding unit 100 grabs the piece of glue to be processed and transfers the piece of glue to the first working position 211, and the glue distributing unit 200 provides buffering of the piece of glue on the first working position 211. The first paper tearing unit 400 tears off the bottom side gummed paper of the gummed paper, and the gummed paper is temporarily stored in the first working position 211; the rubberizing unit 300 can grasp the sheet adhesive located on the first working position 211 and rubberize the battery cell component 930; the third gummed paper clamping jaw 520 clamps the grabbing part of the top gummed paper of the sheet material, and the gummed paper clamping jaw 520 is driven to move in the process that the gummed unit 300 returns from the battery cell component 930 to the gummed unit 200, so that the top gummed paper of the sheet material is separated from the gummed material immediately; the rubberizing unit 300 moves to drive the third gumming claw 520 to tear off the top gummed paper of the material.

When the material is a whole piece of adhesive tape, the feeding unit 100 grabs the whole piece of adhesive tape to be processed and transfers the whole piece of adhesive tape to the first working position 211, the first working position 211 adsorbs the whole piece of adhesive tape, and in the process that the feeding unit 100 returns from the adhesive separating unit 200, the second adhesive tape clamping jaw 510 is driven to move, so that the top side adhesive tape is torn off, and at the moment, the whole piece of adhesive tape positioned on the first working position 211 only remains the middle adhesive substance; glue dispensing device 220 is capable of splitting glue located at first station 211 into individual strips and transferring to second station 212. The taping unit 300 is capable of gripping a separate adhesive strip located on the second work station 212 and taping with the battery cell assembly 930.

In some embodiments, referring to fig. 6 to 10, the glue dispensing apparatus 220 includes a first module 230, a second module 240, a first pitch changing module 250, and a second pitch changing module 260;

the first module 230 includes a first fixing plate 231 and a plurality of first beads 232; the second module 240 includes a second fixing plate 241 and a plurality of second beads 242. In various embodiments of the present application, a plurality refers to two or more.

The first fixing plate 231 is disposed opposite to the second fixing plate 241. The plurality of first beads 232 are movably arranged on the first fixing plate 231, and the plurality of second beads 242 are movably arranged on the second fixing plate 241. The first pitch module 250 is capable of adjusting the spacing between the plurality of first beads 232 and the second pitch module 260 is capable of adjusting the spacing between the plurality of second beads 242. The rest 210 is penetrated between the first fixing plate 231 and the second fixing plate 241 in the first direction.

Specifically, the first fixing plate 231 is disposed opposite to the second fixing plate 241 in the vertical direction. The movable arrays of the plurality of first press strips 232 are arranged on the bottom surface of the first fixing plate 231 facing the second fixing plate 241, wherein the direction of the array of the first press strips 232 is along the first direction, and a gap along the first direction is reserved between two adjacent first press strips 232; similarly, a plurality of second press bars 242 are movably arranged on the top surface of the second fixing plate 241 facing the first fixing plate 231, the direction of the second press bars 242 is also along the first direction, and a gap along the first direction is arranged between two adjacent second press bars 242; in this way, the first pressing strips 232 and the second pressing strips 242 are disposed in one-to-one correspondence with each other, that is, when the first fixing plate 231 and the second fixing plate 241 are close to each other along the vertical direction, the first pressing strips 232 and the second pressing strips 242 are in one-to-one correspondence with each other and are not staggered.

In each embodiment of the present application, the first direction is a horizontal direction and is perpendicular to the vertical direction; the placement frame 210 extends along a first direction, and the first working position 211 and the second working position 212 are respectively located at two ends of the placement frame 210 along the first direction.

Glue dispensing device 220 has a first state and a second state.

The glue dispensing device 220 is in a first state, and the plurality of first pressing bars 232 and the plurality of second pressing bars 242 are spaced from each other. The width of the gap should be higher than the thickness of the whole adhesive tape; in this way, the glue dispensing device 220 can be reciprocally switched between the first working position 211 and the second working position 212 along the first direction without interfering with the glue strip placed on the first working position 211.

The glue dispensing device 220 is in a second state, and the plurality of first pressing strips 232 are abutted against the corresponding plurality of second pressing strips 242. In this manner, a single strip of adhesive can be sandwiched between a pair of first 232 and second 242 beads.

The glue dispensing device 220 is switched between the first state and the second state, and the glue dispensing device 220 is matched with the reciprocating motion of the glue dispensing device 220 on the placement frame 210, so that the whole piece of glue strips positioned at the first working position 211 are split into separate glue strips.

For an example of the whole adhesive tape, referring to fig. 7 to 10, the operation of the first paper tearing unit 400 and the second adhesive tape clamping jaw 510 can be seen, when the adhesive tape is at the first working position 211, the adhesive tape has been torn off by the first paper tearing unit 400 and the second adhesive tape clamping jaw 510 to separate the top adhesive tape and the bottom adhesive tape, and only the middle adhesive material remains. The glue dispensing device 220 is in a first state, and moves to a first working position 211 of the placement frame 210, the glue dispensing device 220 is switched to a second state, the first pressing strips 232 and the corresponding second pressing strips 242 can mutually approach and collide to form clip structures, and each clip structure can independently clip a piece of adhesive tape; the glue separating device 220 moves from the first working position 211 to the second working position 212, so that the single adhesive tape can be separated from the whole adhesive tape; the glue dispensing device 220 moves to the second working position 212 with the single adhesive tape, the glue dispensing device 220 is switched to be in the first state, the first pressing strips 232 and the corresponding second pressing strips 242 are mutually spaced, the single adhesive tape is not clamped any more, and the single adhesive tape is placed on the second working position 212; the subsequent taping unit 300 then removes the detached individual glue strips from the second work station 212 and rubberizes the individual glue strips with the electrical core assembly 930, thereby automatically completing the gluing process.

The first pitch module 250 is capable of adjusting the pitch between the plurality of first beads 232 in the first direction, and the second pitch module 260 is capable of adjusting the pitch between the plurality of second beads 242 in the first direction.

It should be understood that, because the types of the battery cell assemblies 930 are different, the width dimensions of the adhesive tape adhered to the battery cell assemblies 930 can be designed correspondingly; in addition, the whole adhesive tape has dimensional tolerance when cutting the cutter.

The first bead 232 spacing is adjusted by the first pitch module 250; the second distance changing module 260 is used for adjusting the distance between the second pressing strips 242, so that the adhesive dispensing device 220 can split adhesive tapes with different widths along the first direction, and each pair of first pressing strips 232 and the corresponding second pressing strip 242 can be mutually close to each other and accurately clamped on one adhesive tape; and further ensures that the glue dispensing device 220 can reliably complete the function of separating the adhesive tape for the whole piece.

By means of the design, the width of the adhesive tape clamped by the first pressing strip 232 and the second pressing strip 242 can be flexibly adjusted, the situation that the first pressing strip 232 and the second pressing strip 242 are redesigned due to different tolerance and adhesive tapes with different widths is avoided, the use is more flexible, and the cost of the battery cell adhesive tape sticking machine is effectively saved.

In some embodiments, referring to fig. 6-8, the mounting frame 210 includes a plurality of frame bodies 214 extending in a first direction. Each frame 214 may be a metal strip, such as aluminum alloy, stainless steel, etc., having a certain rigidity and strength, and may be coated with an anti-adhesion coating on its surface to prevent adhesion with the glue in the middle of the material 900, thereby preventing failure of the rubberizing process.

Two adjacent frames 214 are spaced apart to form a through slot 213. The width of the through groove 213 between any two frame bodies 214 is consistent, and the width of the through groove 213 can be adjusted to be wider in part and narrower in part according to the needs, specifically based on the design.

As shown in fig. 9 to 12, a plurality of second beads 242 extend in the second direction, and a plurality of top blocks 243 are formed on the second beads 242 at intervals, and the top blocks 243 can be inserted into the through grooves 213. The plurality of top blocks 243 correspond to the through grooves 213, and a gap is formed between two adjacent top blocks 243, and each gap should have a width capable of accommodating the corresponding frame 214, so that the second bead 242 is formed in a rack structure extending in the second direction and is capable of being embedded in the spaced frame 214.

Referring to fig. 9, the glue dispensing device 220 is in a first state, and the first pressing bar 232 and the second pressing bar 242 are spaced apart from each other. At this time, the second pressing bar 242 is located at one side of the mounting frame 210 in the vertical direction, and the first pressing bar 232 is located at the other side of the mounting frame 210 in the vertical direction.

Referring to fig. 10, the glue dispensing device 220 is in a second state, the first pressing strip 232 is in contact with the corresponding second pressing strip 242, the second pressing strip 242 moves from one side to the other side of the mounting frame 210 along the vertical direction, and the direction is vertical upwards in the combined drawing until the top block 243 on the second pressing strip 242 can cross the surface of the mounting frame 210 and protrude, and the first pressing strip 232 and the second pressing strip 242 move in opposite directions, so that contact is formed between the two pressing strips, and an independent glue strip is conveniently clamped.

In some embodiments, referring to fig. 8, the placement frame 210 includes a plurality of second suction structures 215, and the plurality of second suction structures 215 are arranged on the frame 214 along the first direction, thereby facilitating gripping of the adhesive tape.

Specifically, the second adsorption structure 215 may be a hole structure, and the second adsorption structure 215 is disposed on a top end surface of the frame 214 where the material 900 is placed. The second adsorption structures 215 are generally uniformly distributed on each frame 214 along the first direction; however, the second adsorption structure 215 may be disposed relatively more densely in the portion of the frame 214 located in the first working position 211 and the second working position 212, and the second adsorption structure 215 may be disposed relatively more sparsely in the portion of the frame 214 located in the other region.

As for the second adsorption structure 215, it can generate a repulsive or adsorption effect by blowing or generating negative pressure.

For example, the second absorbent structure 215 corresponding to the different strips may be controlled separately; in this way, the glue dispenser 220 can split the whole piece of glue strip located in the first working position 211 into separate glue strips more stably.

Referring to fig. 7 to 10, when the adhesive tape is in the first working position 211, the second adsorption structure 215 in the first working position 211 generates an adsorption effect, so that the adhesive tape of the whole piece can be stably adsorbed on the first working position 211, the second adhesive tape clamping jaw 510 can conveniently tear the top adhesive tape of the whole piece, the abnormal condition that the posture of the adhesive tape of the whole piece deviates at the first working position 211 can be reduced, and the adhesive separating function of the adhesive separating unit 200 is ensured to be stably realized.

The glue dispensing device 220 is in a first state, and moves to a first working position of the placement frame 210, the glue dispensing device 220 is switched to a second state, and the first pressing strip 232 and the corresponding second pressing strip 242 are mutually close to each other to be abutted so as to clamp a single adhesive tape; the glue separating device 220 moves from the first working position 211 to the second working position 212, the second adsorption structure 215a corresponding to the glue strip is changed from vacuum negative pressure adsorption to outward blowing, and other glue strips still remained on the placing frame 210 are still adsorbed and fixed by the other second adsorption structures 215, so that the glue strips can be ensured to be rapidly separated from the whole glue strips on the placing frame 210.
