As shown in fig. 6, the linear moving mechanism 044 may be various devices and structures capable of generating linear movement, and preferably includes a linear servo module 0441 and a guide rail 0442 extending along a length direction of the platen 010, where the linear servo module 0441 is known in the art and will not be described herein. The movable part of the linear servo module 0441 is connected with the mounting seat 0433, and the mounting seat 0433 is slidably arranged on the guide rail 0442.

Further, when the fixing device 03 employs a fixed jaw, the two clamping surfaces of the grasping jaw 040 (the surfaces of the grasping jaw 040 that contact the cell side surfaces) and the two clamping surfaces of the clamping portion 030 of the fixed jaw 03 (the surfaces of the clamping portion 030 that contact the cell side surfaces) are coplanar in the clamped state, and therefore, the positional uniformity of each cell can be effectively ensured.

Since the electric core is at risk of breakage when being pressed too much, in a more preferred structure, as shown in fig. 7, the clamping body 042 comprises a support frame 0421, the support frame 0421 is in an L shape as a whole, a horizontal part of the support frame 0421 is located below the bedplate 010, and vertical parts of the support frame 04are located outside two sides of the bedplate 010.

Further, because a plurality of electric cores need to be attached, therefore in order to accurately know the quantity of the attached electric cores, in a preferred mode, as shown in fig. 8, the outside of the second end 012 of the bedplate 010 is provided with the laser sensor 05 positioned above the second end 012, the laser emitted by the laser sensor 05 is right opposite to the electric cores on the bedplate 010, when an electric core exists, the laser is blocked so as to know the distance between the sensor and the electric core, and the adhered electric cores can be known according to the measured different distances, so that the control of a servo linear module can be carried out by combining an opposite emission sensor and the like.

Since the pressure applied to the cells by the attaching device 04 during attaching is often limited, after all the cells are placed on the platen and pre-attached together, a further pressing mechanism is further needed to fasten the attachment of a group of cells, and in view of this, as shown in fig. 8 and fig. 9, a fastening mechanism 06 is disposed outside the second end 012 of the platen, and the fastening mechanism 06 includes a pressing plate 061 that is located above the platen 010 and is parallel to the limiting surface, and the pressing plate 061 can move back and forth above the platen 010 along the length extension direction.

In addition, in order to avoid the cell overvoltage damage caused by the hard contact between the laminated plate 061 and the cell, the laminated plate 061 is connected with a fastening driving mechanism in a floating mode to drive the laminated plate 061 to move.

As shown in fig. 8 and 9, the fastening driving mechanism includes a large cylinder 062 extending along the length direction of the platen 010, the large cylinder 062 is fixed on a U-shaped plate 063, the movable portion thereof is connected with a sliding seat 064 slidably disposed on the top of the vertical plate 063, the sliding seat 064 is slidably disposed on a guide rail 069 on the top of the U-shaped plate 063, a cross bar 065 is connected with a vertical plate 066 parallel to the pressing plate 061, the vertical plate 066 is provided with a through hole matching with the relief hole of the pressing plate 061, the vertical plate 066 is vertically and slidably provided with two connecting bolts 067 relative thereto, one end of the connecting bolt 067 is connected with the pressing plate 061, and a floating spring 068 between the pressing plate 061 and the vertical plate 066 is sleeved on the periphery of the connecting bolt 067, although other elastic members may be used instead of the floating spring, such as a plurality of metal domes.

In the above embodiment, only the structure of the placement seat 01 cooperating with the limiting surface 02, the fixing device 03, the adhering device 04, the laser sensor 05 and the fastening mechanism 06 is described, which form a processing station. In a more preferred embodiment, in order to improve the assembly efficiency, as shown in fig. 8, the processing stations are preferably multiple (in one group), that is, the placing seats 01 are multiple and arranged side by side, and each placing seat 01 cooperates with one of the limiting surfaces 02, the fixing device 03, the adhering device 04, the laser sensor 05 and the fastening mechanism 06. In the multi-station structure, parts of the plurality of sticking devices 04 can share the same sticking moving device for driving the grabbing jaw 040 to move, for example, when the number of the processing stations is six, the sticking devices 04 at the two middle stations can share one set of servo linear module, and the two stations at the two sides use one servo linear module respectively.

In the configuration of the plurality of processing stations, as shown in fig. 8, the laser sensors 05 of the plurality of processing stations may be disposed on the same T-shaped frame 08 at the same height, the laminated plates of the plurality of fastening mechanisms 06 may be disposed on one cross bar 065 in common, and both ends of the cross bar 065 may be connected to large cylinders, respectively.

Furthermore, the blanking is needed after the attachment is finished, and if only one group of a plurality of processing stations are arranged, the assembly cannot be continuously carried out during the blanking, so that the waste of time is caused. Therefore, as shown in fig. 2 and 8, the stage 00 is disposed on a turntable 07 that drives the stage to rotate, and the specific structure of the turntable 07 is a known technology and is not an innovation point of the present invention, and is not described here again.

The moving device 2150 is preferably located on the horizontal plate 2130, and may be a linear motor or a linear module or a structure formed by a motor and a lead screw and capable of generating linear movement; of course, the device can also be a cylinder, an oil cylinder, an electric push rod and the like. The minimum distance between the two pressing plates 2110 of the pressing mechanism 2100 is the same as the length of the battery cell module, so that the two pressing plates 2110 can effectively position and fix the battery cell module.

After the battery cell module is fixed by the battery cell module locking mechanism 2000, paper removal and cleaning operations can be performed. The paper removing operation is to tear off protective paper (centrifugal paper or centrifugal film) on adhesive layers at two ends of the battery cell module, the paper removing operation is executed by the paper removing mechanism 3000, the cleaning operation is to clean two side surfaces of the battery cell module to remove dirt, and the cleaning operation is executed by the cleaning mechanism 4000.

As shown in fig. 12 and 13, the paper removing mechanism 3000 includes at least one piece located outside the end 1500 of the cell module supporting platform 1000 and capable of reciprocating along the extending direction of the end of the cell module supporting platform 1000, and includes a paper removing clamping jaw 3100, the paper removing clamping jaw 3100 includes a clamping jaw cylinder 3110 and two clamping jaws 3120 driven by the clamping jaw cylinder 3110, the clamping jaw 3120 includes a main body 3121 and a clamping plate 3122, and mutually matching bosses and notches are formed on the opposite end surfaces of the two clamping plates 3122, the bosses extend in the direction perpendicular to the cell module supporting platform 1000, and the bosses are located at the notches when the two clamping jaws clamp, so as to stably clamp the head of the protection paper.

As shown in fig. 12, the linear movement device 3300 is disposed on a driving device 3400 that drives it to reciprocate along an end extending direction (a width direction of the cell module support table) of the cell module support table (1000) by a slider. The slider sets up with sliding on one follows the conducting bar 3500 that the width direction of electricity core module brace table extends. The driving device 3400 may also be various devices capable of generating linear movement, such as an air cylinder or an oil cylinder, and in a preferred embodiment, the driving device 3400 is a linear motor or a linear module, and two ends of the driving device extend to the outer sides of two long sides of the cell module support table 1000. Meanwhile, the driving device 3400 is arranged on the horizontal plate 2130 of the battery cell module locking mechanism and is positioned below the pressing plate 2110 so as to move synchronously with the pressing plate 2110.

In this embodiment, the linear moving device 3300 is exemplified by a cylinder, and when a cylinder shaft of the cylinder extends out, the two clamping jaws 3120 of the paper removing clamping jaw 3100 are located at one end of the adhesive tape on the end surface of the cell module and can clamp the head of the protective paper (release paper or centrifugal film) on the adhesive tape, which extends out of the end surface of the cell module. When the cylinder shaft of the cylinder retracts, the paper removing clamping jaw moves the head of the protective paper clamped by the paper removing clamping jaw towards the direction far away from the end face of the battery cell module, so that the head of the protective paper is separated from the colloid. Then, the driving device 3400 drives the paper removing gripper 3100 to move linearly toward the other end of the protective paper, so that the protective paper can be peeled off from the adhesive layer.

In a further preferred embodiment, in order to avoid the protective paper taking the adhesive layer up during paper removal, in a more preferred mode, as shown in fig. 13, the linear moving device 3300 drives the moving path (direction of reciprocating movement) of the mounting plate 3200 and the included angle a of the short side of the battery cell module supporting table 1000 to form an acute angle, so that the force application direction during tearing the protective paper and the adhesive layer form an acute angle, and separation of the vertical adhesive layer on the tensile force during tearing the protective paper is greatly reduced, thereby greatly reducing the risk of taking the adhesive layer up.

After the tearing device 3000 performs the tearing operation, it is further required to determine whether the protection paper is effectively torn, further, as shown in fig. 10, the device for pretreating the surface of the battery cell module further includes a paper removal determining mechanism 5000 for determining whether the protection paper of the adhesive tape is torn, and the paper removal determining mechanism 5000 may determine whether there is a glue layer in various feasible manners, for example, may measure a distance from a sensor to an end surface of the battery cell module by using a high-precision distance measuring sensor (a laser sensor, etc.), so as to determine whether the protection paper is torn.

In an alternative mode, the protection paper and the glue layer are arranged, and due to the brightness difference between the protection paper and the glue layer, the brightness detected by the brightness sensor can determine whether the protection paper or the glue layer is used.

In a more preferable mode, the tearing of the protective paper is determined by arranging a color scale sensor which is arranged on the paper removing clamping jaw 3100 through a bracket, is positioned below the pressing plate and moves synchronously with the paper removing clamping jaw 3100, namely the color scale sensor is also arranged on the linear moving device 3300, and the tearing of the protective paper is determined by identifying different colors of the white release paper and the black glue layer through the color scale sensor.

Further, after the paper removing mechanism 3000 removes the protection paper, the protection paper needs to be discarded before the next removal operation can be performed. As shown in fig. 10, in order to effectively collect the protection paper and prevent the torn protection paper from polluting the working environment, a protection paper collector 6000 is disposed at one end of the paper removing mechanism 3000, the protection paper collector 6000 includes a feeding hopper 6100 and a collecting box 6200, and the protection paper collector 6000 is preferably disposed right below a position where the paper removing claw of the paper removing mechanism 3000 is moved when the protection paper is torn, so that the paper removing claw holding the protection paper can be immediately opened to discard the protection paper into the protection paper collector 6000.

In view of the light weight of the protection paper and the tendency to be scattered around by the air flow, in a more preferred embodiment, as shown in fig. 10, a blowing device 7000 for forming the air flow toward the protection paper collector 6000 is disposed above the paper removing mechanism 3000, and the blowing device 7000 may be any device capable of generating the air flow flowing in a certain direction, such as a blower, a fan, etc., and is not limited herein.

As shown in fig. 10 and 13, the cleaning mechanism 4000 includes a cleaning device 4100 located outside the side 1600 (long side) of the cell module support table 1000, and the cleaning device 4100 can at least reciprocate along the side extension direction of the cell module support table 1000, and can move from one end of the cell module support table 1000 to the other end, so as to clean the long side of the cell module on the cell module support table 1000.

In yet another possible embodiment, the cleaning device 4100 is a cleaning head of an ultrasonic cleaning machine, so that ultrasonic cleaning can be performed.

In a preferred embodiment, the cleaning device 4100 may further include two plasma cleaning guns, and in a more preferred manner, the two plasma cleaning guns have a height difference and are arranged in a longitudinally staggered manner, so that the two plasma cleaning guns can completely cover the side surfaces of the cell module to complete the complete cleaning of one side surface of the cell module in one cleaning process.

Of course, in other embodiments, only one plasma cleaning gun may be provided, and the entire side surface of the cell module may be covered by moving the cleaning apparatus 4100 up and down.

As shown in fig. 13 and 14, the cleaning device 4100 is connected to a cleaning moving device 4200 that drives the cleaning device 4100 to reciprocate along the longitudinal direction of the cell module support table, the cleaning moving device 4200 may be any device capable of generating linear movement, such as an air cylinder, an oil cylinder, or the like, and preferably is a linear motor or a linear module or a structure formed by a motor and a lead screw, and the cleaning moving device 4200 drives the cleaning device 4100 to move from the outer side of one end of the cell module support table to the outer side of the other end.

Further, since the head of the cleaning device 4100 needs to be kept at a short distance from the side surface of the cell module during cleaning, in the above structure, as shown in fig. 13 and 14, the head of the cleaning device 4100 may interfere with the placement of the cell module on the cell module support table 1000, and therefore, in a more optional manner, the cleaning device 4100 may also reciprocate along the width direction of the cell module support table. Specifically, two of the cleaning devices 4100 are disposed on an upper L-shaped member 4300, a slide rail 4400 extending in the width direction of the cell module support table is disposed at the bottom of the L-shaped member 4300, the slide rail 4400 is slidably disposed on a guide block, the L-shaped member 4300 is connected to a push-pull cylinder 4500 driving the L-shaped member 4300 to reciprocate in the extending direction of the slide rail 4400, the push-pull cylinder 4500 and the guide block 4800 are both disposed on a bottom plate 4600, the bottom plate 4600 is fixed to a movable portion of the cleaning moving device 4200, and the bottom plate 4600 is slidably disposed on a rail 4700 extending in the length direction of the cell module support table.

On the other hand, the rear end of each cleaning device 4100 is connected to a cable or pipe (not shown) which may hang down under gravity, causing an abnormality (leakage or damage, etc.) in the position where it engages with the cleaning device 4100, thereby suspending the cable or pipe on a lifting rope which keeps the cable or pipe at a similar height or in a nearly coaxial state with the cleaning device 4100.

Further, as shown in fig. 10 and 15, a code scanning mechanism 8000 is further disposed on the bottom plate 4600, the code scanning mechanism 8000 includes an upright 8100 disposed on the bottom plate 4600, a stage 8200 is disposed on the upright 8100, a cylinder 8300 is disposed on the stage 8200, a cylinder shaft of the cylinder 8300 extends along a width direction of the electrical core module supporting stage and is connected to a frame 8600, and a code scanner 8400 with a downward lens and a light source 8500 with a downward light emitting surface are disposed on the frame 8600.

In the above configuration, since there is only one paper removing mechanism 3000 and one cleaning mechanism 4000, the paper removing operation and the cleaning operation of one side surface of the cell module can be performed at a time.

After once paper removal and cleaning operation, the battery cell module can be horizontally rotated by 180 degrees through manual or automatic equipment, and then paper removal of the other end face and cleaning of the other side face are carried out.

When the rotation of the battery cell module is realized by using the automation equipment, the rotation may be realized in different manners, for example, in a feasible manner, the battery cell module supporting table may be a rotatable structure, and the battery cell module supporting table is connected to a rotation driving mechanism for driving the rotation of the battery cell module supporting table, at this time, the battery cell module supporting table may be a circular table, the bottom of the circular table is coaxially connected to a rotating shaft (not shown in the figure), the rotating shaft is connected to an inner hole of a bearing on the workbench, and the rotating shaft is connected to a motor for driving the rotation of the battery cell module supporting table directly or through a transmission structure.

In another embodiment, a mobile robot, for example, a six-axis robot, may be further disposed on the workbench, and the battery cell module is rotated by 180 degrees by the robot, which is a known technology and is not described herein again.

In other embodiments, the cleaning mechanism and the paper removing mechanism may even be rotated by 180 °, and the specific rotating structure here is the prior art and the implementation structure is complex, which is not a design point of the present solution, and therefore, details are not described here.

In a preferred embodiment, as shown in fig. 10 and 13, the paper removing mechanism 3000 and the cleaning mechanism 4000 are both two, and in a normal state, the paper removing claws 3100 of the two paper removing mechanisms 3000 are diagonally distributed, the cleaning devices 4100 of the two cleaning mechanisms 4000 are diagonally distributed, and the diagonal lines of the two paper removing claws 3100 intersect with the diagonal lines of the two cleaning devices 4100, so that when the four components work simultaneously, the interference between the four components can be effectively avoided, the matching degree between the four components is improved, the working cycle is improved, and the efficiency is improved.

As shown in fig. 16 and 17, the battery pack assembling apparatus 30 includes a support 100, where the support 100 may be a structure formed by various known profiles and/or plates, and preferably includes a lower layer 110 and an upper layer 120 formed by a plurality of criss-cross profiles, and the support 100 is further provided with a cell module placing table 200, a cell module fixing mechanism 300, an end attaching mechanism 400, and a partition limiting mechanism 500.

As shown in fig. 17, the cell module placing table 200 is configured to place two cell modules side by side, and is erected on the upper layer 120, and includes a rectangular bottom plate 210 and a rectangular supporting plate 220 fixed on the bottom plate 210, where the width of the supporting plate 220 may be designed as required, and is preferably greater than the sum of the widths of the two cell modules and the thickness of the partition plate. And, be formed with the position respectively on bottom plate 210 and the backup pad 220 and be close to the dodge hole 230 of their minor face both ends relatively, dodge hole 230 is used for whether battery cell module has been placed to the corresponding position of sensor response.

Of course, in other embodiments, the cell module placing table 200 may also be made of a plate material with other shapes, for example, a circular disc, an elliptical disc, or another polygonal plate-shaped object. In addition, the battery cell module placing table 200 can also be a structure assembled by criss-cross or parallel sectional materials, so that the two battery cell modules can be supported as standard.

As shown in fig. 16 to fig. 18, the cell module fixing mechanism 300 is configured to position the cell module located on the cell module placing table 200 and attach two cell modules and a partition plate together, and includes pressure applying mechanisms located on four sides of the cell module placing table 200, where the pressure applying mechanisms are opposite to each other, and apply pressure opposite to each other to the cells on the cell module placing table 200.

Specifically, as shown in fig. 17 and fig. 18, the cell module pressing mechanism includes a first pressing mechanism 310 and a second pressing mechanism 320 located on the left and right sides of the cell module placing table 200, and a third pressing mechanism 330 and a fourth pressing mechanism 340 located on the upper and lower sides of the cell module placing table 200. The first pressing mechanism 310 and the second pressing mechanism 320 are both disposed on the lower layer 110 of the bracket 100, and the structures of the two mechanisms are the same, and the first pressing mechanism 310 is taken as an example in the following embodiments.

As shown in fig. 18 to fig. 20, the first pressing mechanism 310 includes a pressing block 311, and the pressing block 311 has a height that is just above the adhesive layer of the end surface of the cell module on the cell module placing table 200, so as to avoid damaging the adhesive layer when applying a force. The distance between the length of the pressing block 311 from one end to the other end may be designed according to needs, for example, the length of the pressing block 311 is greater than the width of the cell module support table 200, or the lengths of the pressing block 311 and the cell module support table are equivalent; or the length of the pressing block 311 is equivalent to the sum of the widths of the two cell modules; preferably, two ends of the pressing block 311 extend to the outer sides of two long sides of the cell module supporting table 200.

The pressing block 311 is connected to a moving device for driving the pressing block to linearly reciprocate along the left-right direction, the moving device may be any known device or structure capable of generating linear movement, for example, a cylinder, an oil cylinder or an electric push rod, or a structure formed by a motor and a lead screw, and the like, in a preferred embodiment, as shown in fig. 19 and fig. 20, the moving device includes a first cylinder 312, the first cylinder 312 is fixed on a portal frame 313 located on the lower layer 110, a cylinder shaft of the first cylinder 312 is vertically connected with the pressing block 311, a guide post 314 is also vertically connected to the pressing block 311, and the guide post 314 is slidably inserted into a guide sleeve 315 fixed on the portal frame 313.

At this time, when the cylinder shafts of the two first cylinders of the first pressing mechanism 310 and the second pressing mechanism 320 extend out, the distance between the two pressing blocks is the same as the width of the cell module.

Because the cylinder volume that the removal of big stroke needs is great, and the back is contacted with the electric core module to the briquetting simultaneously, and especially when two briquetting distances are minimum, the impact to the electric core module is great, easily causes the damage of electric core module, therefore, in preferred structure, make the stroke of first cylinder 312 reduces, after the cylinder shaft of first cylinder 312 stretches out, briquetting 311 has not contacted with the both ends of electric core module yet, increases another level translation structure this moment and makes two briquetting 311 remove to the target interval.

Continuing with the description of the first pressing mechanism 310 as an example, as shown in fig. 19 and fig. 20, the first cylinder 312, the guide rod, the guide sleeve, the gantry and the like form a primary push-pull mechanism, the primary push-pull mechanism is disposed on a secondary push-pull mechanism, the secondary push-pull mechanism includes a carrier plate 316, the carrier plate 316 is slidably disposed on a guide rail 318 fixed on the lower layer 110 through a slider 317, the guide rail 318 extends in a direction parallel to the length direction of the battery cell module placing table, and the carrier plate 316 is connected to a second cylinder 319 driving the carrier plate to slide along the guide rail 318. Of course, the second cylinder may be replaced by a cylinder, an electric cylinder, or the like capable of generating linear movement.

The respective moving strokes of the second cylinder 319 and the first cylinder 312 may be limited according to actual requirements, for example, the grooves of the two cylinders may be the same or different; in a preferred structure, as shown in fig. 19, the first cylinder 312 is a small cylinder with a smaller stroke, the second cylinder is a large cylinder with a stroke larger than that of the first cylinder 312, and when pressure is applied, the cylinder shaft of the second cylinder preferably extends first, and then the cylinder shaft of the first cylinder extends.

The above embodiment is described by taking the same structure of the first pressure applying mechanism 310 and the second pressure applying mechanism 320 as an example; of course, in other embodiments, the structures of the first pressing mechanism 310 and the second pressing mechanism 320 may also be different, for example, one of the first pressing mechanism 310 and the second pressing mechanism 320 has a one-stage push-pull structure, and the other has a two-stage push-pull structure; or one of the power sources of the first pressure applying mechanism 310 and the second pressure applying mechanism 320 is an air cylinder, and the other is a motor.

As shown in fig. 20, the third pressing mechanism 330 and the fourth pressing mechanism 340 have a similar structure to the first-stage push-pull mechanism of the first pressing mechanism 310, except that the

pressing blocks

331 and 341 of the third pressing mechanism 330 and the fourth pressing mechanism 340 have a length and a width equivalent to those of the cell module. As shown in fig. 13, the moving devices of the third pressing mechanism 330 and the fourth pressing mechanism 340 may be electric push rods with

motors

332 and 342 as power sources, so that the moving distances of the pressing heads controlling the third pressing mechanism 330 and the fourth pressing mechanism 340 may be adjusted. Of course, the moving devices of the third pressing mechanism 330 and the fourth pressing mechanism 340 may also use an air cylinder, an oil cylinder, or the like.

Further, in a more preferred embodiment, in order to reduce the impact on the battery cell module caused by the pressing head when the pressing head applies pressure, as shown in fig. 20 to 22, four buffer pads 350 are further disposed on the end surfaces of the pressing heads of the pressing mechanisms, which face the battery cell module placing table, where the buffer pads 350 may be made of soft materials such as a silica gel pad and a rubber pad, and at this time, the distance between the opposite pressing heads may be adaptively adjusted according to the thickness of the buffer pads 350.

As shown in fig. 17, the two end attaching mechanisms 400 are located outside the two ends of the cell module placing table 200, and are configured to fix the two ends and attach the two end ends to the two ends of the cell module. As shown in fig. 19 and 20, each of the terminal attachment mechanisms 400 has a support table 410 and a fixing mechanism 420, which are synchronously movable with respect to the cell module placing table 200.

Specifically, as shown in fig. 19, the support table 410 is an L-shaped member, and includes a bottom plate 411 parallel to the top surface of the cell module placing table 100 and higher than the cell module placing table 100, and a vertical plate 412 thereon, where the width of the bottom plate 411 may be smaller than the width of the terminal, or may be larger than the width of the terminal, and is preferably smaller than the width of the terminal. The length of the riser 412 is less than the length of the head, but the length of the head may be equal to or greater than the length of the head, so the length of the riser 412 is less than the length of the head, which is convenient for the arrangement of the fixing device 420. The support table 410 has the top of the tip thereon no higher than the bottom surface of the platen of the first pressing mechanism 310.

As shown in fig. 19 and 20, the fixing device 420 may be any known fixing structure, for example, a set of vacuum suction holes, not shown, may be formed on the bottom plate 411 and/or the riser 412, and the vacuum suction holes may be connected to a vacuum pumping apparatus, so that the head may be fixed by suction through the vacuum suction holes. Alternatively, when the end is a magnetizer, the bottom plate 411 and/or the vertical plate 412 may be a magnet; alternatively, a hold-down mechanism may be provided on the riser 412, and the hold-down mechanism may apply a hold-down force to the head of the bottom plate 411 to hold the head against the bottom plate 411.

In a preferred embodiment, as shown in fig. 19 and fig. 20, the fixing device 420 includes a clamping jaw air cylinder 421 fixed on the vertical plate 412, two movable blocks of the clamping jaw air cylinder 421 are respectively connected to a clamping plate 422, the two clamping plates 422 are located outside two sides of the vertical plate 412, and the clamping jaw air cylinder 421 drives the two clamping plates 422 to contract or open so as to clamp or release the end head located on the bottom plate 411.

As shown in fig. 19 and 20, the supporting table 410 and the fixing mechanism 420 are further connected to a translation mechanism 430 for driving them to synchronously and linearly move, and the translation mechanism 430 may be a device or a structure for driving them to linearly and reciprocally move along a direction parallel to the length direction of the cell module placing table, and may be, for example, an air cylinder or an oil cylinder. Preferably, the battery cell module placing table comprises a third cylinder 431, the third cylinder 431 is connected to a support plate 432 and drives the support plate 432 to reciprocate along a sliding block 434 through a sliding rail 433 at the bottom of the third cylinder 431, the sliding rail 433 extends in a direction parallel to the length direction of the battery cell module placing table, and the support table 410 is arranged on the support plate 432.

The moving strokes of the third cylinders 431 of the two translation structures 430 may be designed as required, and similarly, the moving strokes may drive the distance between the opposite end surfaces of the terminals located on the support table 410 to be consistent with the length of the cell module, so that the two terminals may be effectively attached to the two ends of the cell module.

At this time, of course, there is also a problem of large impact due to a large stroke, therefore, as shown in fig. 19, the translation mechanism 430 may also adopt a two-stage translation mechanism, and in a preferred embodiment, the third cylinder 431, the slide rail 433 and the slider 434 are disposed on the bearing plate 316 of the first pressing mechanism 310, so that the translation mechanism 430 does not need to additionally provide a one-stage translation structure, and at this time, the third cylinder 433 may adopt a cylinder with a small stroke, which can reduce the impact on the cell module during attachment, and can simplify the structure, so that the overall structure is more compact.

When the terminal is placed on the supporting table 410, the terminal does not fit to the vertical plate 412 of the supporting table 410, and a position error occurs, so that the precision of subsequent assembly is reduced, therefore, as shown in fig. 9, the battery pack assembling device further includes two terminal pre-positioning mechanisms 600, and each terminal pre-positioning mechanism 600 is matched with one terminal attaching mechanism 400.

As shown in fig. 23 and fig. 24, the tip pre-positioning mechanism 600 includes a pressing head 610, the pressing head 610 can translate between the cell module placing table 200 and the support table 410, and the pressing head 610 can move from below the top surface of the cell module placing table 200 to above the top surface.

Specifically, the pressing head 610 is preferably a flat plate, and is perpendicular to the length direction of the electrical module placing table. It may of course also be of other shapes, for example an L-shaped or a cylindrical member.
