When the mounting seat 21 moves to the lug turnover station, the mounting seat 21 is located above the bearing assembly 11, and in the process of descending the mounting seat 21, the first positioning piece 23 can be inserted between the battery cell A1 and the adaptor piece A3 on the battery cell A1, and the second clamping assembly 22 can control the two second clamping blocks 221 to clamp the battery cell A1.

Thus, when the tab A2 of the battery cell A1 on the first support frame 110 needs to be bent, first, the mounting seat 21 is controlled to move to the tab folding station. Then, the mounting base 21 is controlled to descend, so as to drive the second clamping assembly 22 and the first positioning sheet 23 to move toward the battery cell A1 on the first support frame 110, until the battery cell A1 is located between the two second clamping blocks 221, and the first positioning sheet 23 is inserted between the battery cell A1 and the adapter sheet A3. Then, the tab A2 of the battery cell A1 is turned over by using the tab turning-over mechanism 10, so that the adapter sheet A3 on the tab A2 can be positioned by using the first positioning sheet 23, and the adapter sheet A3 can be turned over in place along with the tab A2.

When the battery cell A1 on the first support frame 110 needs to be transported to the stacking station, the second clamping assembly 22 controls the two second clamping blocks 221 to clamp the battery cell A1, and controls the mounting base 21 to ascend to the initial position. Finally, the mounting base 21 is controlled to move to the stacking station, and the battery cell A1 is released to the stacking station.

It should be noted that, when the tab A2 on the electric core A1 is turned over, the first positioning piece 23 inserted between the electric core A1 and the adapter piece A3 on the electric core A1 is used to position the adapter piece A3, which is beneficial to improving the position accuracy of the adapter piece A3, and further improving the welding quality.

In the embodiment, the first transfer mechanism 20 further includes a first moving driving assembly (not shown) which is drivingly connected to the mounting base 21 to drive the mounting base 21 to move between the tab folding station and the stacking station, and also to drive the mounting base 21 to ascend or descend. It should be noted that, the first moving driving assembly may adopt a mature prior art, as long as it can drive the mounting seat 21 to move between the tab folding station and the stacking station, and further drive the mounting seat 21 to ascend or descend, and is not limited herein.

In particular embodiments, the second clamping assembly 22 also has two oppositely disposed third clamping blocks 222. When the second clamping assembly 22 controls the two second clamping blocks 221 to clamp the battery cell A1, the second clamping assembly 22 can control the two third clamping blocks 222 to clamp the interposer A3 on the tab A2 of the battery cell A1. Thus, the two third clamping blocks 222 are utilized to clamp the contact piece A3, so that the contact piece A3 is positioned, and the contact piece A3 is further prevented from generating position deviation in the transferring process.

Alternatively, two second clamping blocks 221 are oppositely arranged along the second horizontal direction Y, and two third clamping blocks 222 are oppositely arranged along the second horizontal direction Y. The second horizontal direction Y is parallel to the width direction of the battery cell A1 carried on the carrier assembly 11. In this way, the two second clamping blocks 221 are used for clamping the battery cell A1 along the second horizontal direction Y (i.e., the width direction of the battery cell A1), and the two third clamping blocks 222 are also used for clamping the interposer A3 along the second horizontal direction Y.

In a particular embodiment, the second clamp assembly 22 includes a second clamp drive member 223 and first and second transfer blocks 224, 225 coupled to the drive end of the second clamp drive member 223. The second clamp driving member 223 is used to drive the first moving block 224 and the second moving block 225 toward or away from each other.

The two second holding blocks 221 are respectively connected to the first moving block 224 and the second moving block 225 so as to follow the first moving block 224 and the second moving block 225 to approach or separate from each other. The two third holding blocks 222 are connected to the first moving block 224 and the second moving block 225, respectively, so as to follow the first moving block 224 and the second moving block 225 toward or away from each other. In this way, when the battery cell A1 needs to be clamped, the second clamping driving component 223 drives the first moving block 224 and the second moving block 225 to approach each other, so as to drive the two second clamping blocks 221 to approach each other until the battery cell A1 is clamped, and simultaneously drive the two third clamping blocks 222 to approach each other until the clamping adaptor piece A3. Alternatively, the second clamp drive 223 may employ a pneumatic gripper.

Further, the first moving block 224 may be disposed on the mounting base 21 by means of a slider and a slide rail, so that the movement of the first moving block 224 relative to the mounting base 21 is guided by the slider and the slide rail. Similarly, the second moving block 225 may also be disposed on the mounting base 21 through a slider and a slide rail, so that the second moving block 225 is guided to move relative to the mounting base 21 through the slider and the slide rail.

Specifically, in the embodiment, the lower side of the mounting seat 21 has the adsorption surface 211 for adsorbing the battery cell A1, so that the battery cell A1 can be adsorbed and fixed by using the adsorption surface 211 on the mounting seat 21 while the battery cell A1 is clamped by using the second clamping assembly 22 during transportation of the battery cell A1, thereby ensuring stable and reliable grasping of the battery cell A1 during transportation, and avoiding the battery cell A1 from dropping halfway or shifting in parameter position.

Alternatively, the suction surface 211 may be subjected to negative pressure suction, for example, the suction surface 211 is provided with a plurality of suction holes communicating with an external negative pressure source, and the suction holes generate negative pressure, thereby generating suction force on the battery cell A1. Of course, in other embodiments, a suction cup may be disposed on the suction surface 211, so that the electric core A1 is sucked by the suction cup.

In an embodiment, the two third clamping blocks 222 have second positioning grooves 2221 (see fig. 14) formed on the sides facing each other. When the second clamping assembly 22 controls the two second clamping blocks 221 to clamp the interposer A3 on the tab A2 of the battery cell A1, the interposer A3 enters the second positioning grooves 2221 of the two third clamping blocks 222, so that the interposer A3 is positioned. Thus, the second positioning grooves 2221 for accommodating the adaptor pieces A3 are formed in the two third clamping blocks 222, which is beneficial to improving the positioning effect of the adaptor pieces A3 and improving the positioning accuracy.

It should be noted that, the two ends of the battery cell A1 are both provided with tabs A2, and each tab A2 is provided with an adaptor piece A3. In order to position the adaptor pieces A3 at both ends of the battery cell A1 during the transportation process, in an embodiment, the two ends of the mounting seat 21 along the first horizontal direction X are both provided with the second clamping assembly 22 and the first positioning piece 23, and the first horizontal direction X is parallel to the longitudinal direction of the battery cell A1 carried on the carrying assembly 11. In this way, the adaptor sheet A3 at one end of the battery cell A1 is positioned by the second clamping assembly 22 and the first positioning sheet 23 at one end of the mounting seat 21, and the adaptor sheet A3 at the other end of the battery cell A1 is positioned by the second clamping assembly 22 and the first positioning sheet 23 at the other end of the mounting seat 21. Specifically, in the embodiment shown in fig. 11, the second clamping assembly 22 and the first positioning sheet 23 are disposed at both left and right ends of the mounting seat 21, and the adaptor sheet A3 at the left end of the battery cell A1 is positioned by using the second clamping assembly 22 and the first positioning sheet 23 at the left end of the mounting seat 21. The adapter sheet A3 at the right end of the battery cell A1 is positioned by the second clamping assembly 22 and the first positioning sheet 23 at the right end of the mounting seat 21.

Referring to fig. 15 to 17, in an embodiment of the present invention, the stacking and tilting mechanism 30 includes a fixing base 31, a tilting base 32, a second supporting frame 33 and a third clamping assembly (not shown). The tilting seat 32 is connected to the fixed seat 31 in a controlled rotatable manner, so that the tilting seat 32 can be controlled to rotate relative to the fixed seat 31. The second support bracket 33 is connected to the flipping base 32 to rotate together with the flipping base 32 relative to the fixed base 31. The second support frame 33 has a second support position (not shown) for carrying the battery cell group A4, that is, the first transfer mechanism 20 sequentially stacks a plurality of battery cells A1 on the second support position, so as to form the battery cell group A4 supported on the second support position. The third clamping assembly is arranged on the second support frame 33 and/or the overturning seat 32 and is used for fixing the electric core group A4 carried on the second support position. In this way, first, the second support position of the second support frame 33 carries the battery cells A1 transferred by the first transfer mechanism 20 until the battery cell group A4 formed by stacking a certain number of battery cells A1 is formed on the second support position. Then, the cell group A4 is fixed by the third clamping assembly, that is, each cell A1 of the cell group A4 is fixed relative to the second support frame 33. Then, the turning seat 32 is controlled to rotate 90 degrees relative to the fixed seat 31, so that the battery cell group A4 on the second supporting position is turned to the horizontal stacking state from the vertical stacking state, and the stacking and turning of the battery cell A1 are realized.

Specifically, in the embodiment, the stacking and overturning mechanism 30 further includes a plurality of first adaptor plate positioning assemblies 35 corresponding to the adaptor plates A3 on the electric cores A1 of the electric core group A4 one by one. Each first connecting piece positioning component 35 includes a second positioning driving member 351 and a first positioning block 352. The second positioning driving member 351 is mounted on the second supporting frame 33 and is drivingly connected to the first positioning block 352 to drive the first positioning block 352 to move between the positioning position and the avoiding position. When the first positioning block 352 moves to the positioning position, the first positioning block 352 contacts with one side of the corresponding adaptor sheet A3 on one battery cell A1, which is away from the battery cell A1. When the first positioning block 352 moves to the avoiding position, the first positioning block 352 is separated from the adaptor piece A3 on the battery cell A1. Thus, after the first transfer mechanism 20 transfers the first electrical core A1 to the second support position of the second support frame 33, the first positioning block 352 corresponding to the adaptor sheet A3 of the first electrical core A1 is driven by the second positioning driving member 351 to move to the positioning position, so as to position the adaptor sheet A3 of the first electrical core A1, and avoid the adaptor sheet A3 from generating position deviation in the process of turning. After the first transferring mechanism 20 stacks the second electrical core A1 onto the first electrical core A1, the first positioning block 352 corresponding to the second electrical core A1 is driven by the second positioning driving member 351 to move to the positioning position, so that the interposer A3 of the second electrical core A1 is positioned, and the interposer A3 is prevented from being displaced in the process of overturning. Analogize with this, until accomplishing piling up (for example piling up three electric core A1) of the electric core A1 of required quantity to all fix a position keysets A3 on each electric core A1. Alternatively, the second positioning driver 351 may employ an air cylinder.

Further, a suction cup is disposed on a side surface of the first positioning block 352, which is in contact with the interposer A3. So, when first locating block 352 removed to the locating position, the sucking disc on first locating block 352 and the adaptor piece A3 on the electric core A1 that corresponds adsorb fixedly to the realization is to the location of adaptor piece A3.

Furthermore, a positioning portion 3521 is convexly provided on a side surface of the first positioning block 352, which is in contact with the interposer A3. When the first positioning block 352 moves to the positioning position, the positioning portion 3521 contacts with the top of the interposer A3, so as to position the interposer A3 in the height direction.

Further, the second positioning driving member 351 drives the first positioning block 352 to move along the first horizontal direction X, and the third clamping assembly limits the electric core assembly A4 along the second horizontal direction Y. The first horizontal direction X is parallel to the length direction of the battery cell A1 on the second support position, and the second horizontal direction Y is parallel to the width direction of the battery cell A1 on the second support position.

It should be noted that, because the two lengthwise ends of each electric core A1 are provided with the tabs A2, and each tab A2 is provided with the adapter sheet A3, the two ends of the second support frame 33 in the first horizontal direction X are provided with the first adapter sheet positioning assemblies 35 having the same number as the electric cores A1 of the electric core group A4, and the adapter sheets A3 at the two lengthwise ends of each electric core A1 of the electric core group A4 are positioned respectively.

Specifically, in the embodiment, the third clamping assembly includes a first lifting driving member 341, a fourth clamping block 342, and a fixed clamping block 349. The second support bracket 33 is disposed on the flipping base 32. The first lifting driving member 341 is installed on the second supporting frame 33 and is in driving connection with the fourth clamping block 342 to drive the fourth clamping block 342 to lift to or away from one side of the second supporting position in the second horizontal direction Y. The fixed clamping block 349 is installed on the second support bracket 33 and is located at the other side of the second support position in the second horizontal direction Y. In this way, when stacking the battery cells A1, the first transfer mechanism 20 transfers the battery cells A1 one by one to the second support position, and positions each of the battery cells A1 stacked on the second support position by using the fixing clamping block 349. After the battery cells A1 are stacked, the first lifting driving member 341 drives the fourth clamping block 342 to lift to reach one side of the second supporting position departing from the fixed clamping block 349, that is, each battery cell A1 between the fourth clamping block 342 and the fixed clamping block 349 is limited in the second horizontal direction Y. Alternatively, the first elevating driving member 341 may employ a cylinder.

Further, the third clamping assembly further includes a fixing plate 343, a pressing driving member 36, a clamping driving member 344, and a fifth clamping block 345. The fixing plate 343 is connected to the second supporting frame 33 in a liftable manner, and the abutting driving member 36 is mounted on the second supporting frame 33 and is in driving connection with the fixing plate 343 to drive the fixing plate 343 to ascend or descend relative to the second supporting frame 33. The clamping driving member 344 is mounted on the fixing plate 343 and is drivingly connected to the fifth clamping block 345 to drive the fifth clamping block 345 to move to the pressing position or the avoiding position along the horizontal direction (e.g., the second horizontal direction Y).

When the fifth clamping block 345 moves to the pressing position, the fifth clamping block 345 is located above the second supporting position, so that when the pressing driving member 36 drives the fixing plate 343 to descend, the fifth clamping block 345 can be driven to press against the top surface of the electric core assembly A4 on the second supporting position. When the fifth clamping block 345 moves to the avoiding position, the fifth clamping block 345 exits above the second supporting position so as to avoid the action of transferring the battery cores A1 one by one to the second supporting position by the first transfer mechanism 20. Alternatively, the clinch driver 36 may employ an air cylinder.

In particular embodiments, the stacking and flipping mechanism 30 includes a first state and a second state. When the stacking and overturning mechanism 30 is in the first state, the first lifting driving member 341 drives the fourth clamping block 342 to lift to a side away from the second supporting position in the second horizontal direction Y, and the clamping driving member 344 drives the fifth clamping block 345 to be located at the above-mentioned avoiding position. At this time, the first transfer mechanism 20 stacks the battery cells A1 one by one onto the second support position until a required number of battery cells A1 are stacked onto the second support position. It is understood that, in the process of stacking the battery cell A1, the battery cell A1 is positioned in the width direction thereof by the fixing and holding block 349, and the battery cell A1 is positioned in the length direction thereof by the first positioning block 352.

When the stacking and overturning mechanism 30 is in the second state, the first lifting driving member 341 drives the fourth clamping block 342 to lift to reach one side of the second supporting position in the second horizontal direction Y, so as to limit the electric core assembly A4 on the second supporting position in the second horizontal direction Y together with the fixed clamping block 349. Also, the clamp driving member 344 drives the fifth clamping block 345 to move to the abutting position in the horizontal direction. At this time, when the fastening driving member 36 drives the fixing plate 343 to descend, the fifth clamping block 345 can be driven to abut against the top surface of the electric core assembly A4 on the second supporting position, that is, the electric core assembly A4 is pressed and fixed on the second supporting frame 33. Then, the control overturning seat 32 drives the electric core group A4 to overturn for 90 degrees, so that the electric core group A4 is overturned from the vertical stacking state to the horizontal stacking state.

In one embodiment, the stacking and overturning mechanism 30 further comprises an overturning driving assembly 37, and the overturning driving assembly 37 comprises an overturning driving member, a driving wheel, a driven wheel and a transmission belt. The flipping base 32 is rotatably connected to the fixed base 31 through the flipping shaft 321. The upset driving piece is installed on fixing base 31, and the action wheel is installed on the output shaft of upset driving piece, installs on trip shaft 321 from the driving wheel, and the drive belt cover is established between action wheel and the follow driving wheel. So, when needs drive upset seat 32 upset, upset driving piece drive action wheel rotates, and the action wheel passes through the drive belt and drives from the driving wheel rotation, drives trip shaft 321 from the driving wheel and rotates, and then trip shaft 321 drives upset seat 32 and rotates. Alternatively, the tumble drive may employ a motor.

It should be noted that the turnover driving assembly 37 is not limited to the belt transmission structure for turning over the turnover seat 32. Of course, other rotation transmission structures may be adopted, for example, a structure in which the motor is connected to the turning shaft 321 through a speed reducer may be adopted, and the structure is not limited herein.

Of course, in order to further enhance the positioning effect of the rotating tab A3 during the turning process, in other embodiments, the third clamping assembly further comprises a mounting plate and a second positioning plate. The mounting plate is mounted at the drive end of the clamp drive 344 for movement in the second horizontal direction Y by the clamp drive 344. The fifth clamping block 345 and the second locating tab are mounted on the mounting plate. When the fifth clamping block 345 presses the cell group A4 onto the second support frame 33, the second positioning plate is inserted between each cell A1 of the cell group A4 and the adaptor plate A3 thereon.

In this way, when the fifth clamping block 345 is required to clamp the electric core assembly A4, the clamping driving member 344 drives the fifth clamping block 345 to move to the abutting position along the second horizontal direction Y through the mounting plate. Then, the fastening driving member 36 drives the fixing plate 343 to descend until the fifth clamping block 345 is driven to press the top surface of the electric core assembly A4 on the second supporting position, that is, the electric core assembly A4 is pressed and fixed on the second supporting frame 33. Meanwhile, the second locating plate on the mounting plate is inserted between each electric core A1 of the electric core group A4 and the adaptor A3 thereon by the top of the electric core group A4, so that the second locating plate is utilized to locate each adaptor A3, the position deviation of the adaptor A3 in the overturning process of the electric core group A4 is further prevented, and the welding quality during the subsequent welding is favorably improved.

Referring to fig. 18 to 20, in an embodiment of the present invention, the second transfer mechanism includes a jaw seat 38, a jaw (not shown), and a second adaptor plate positioning assembly (not shown). The jaw mount 38 is controllably movable between a stacking station and an assembly station, with the jaws mounted on the jaw mount 38. The second adaptor piece positioning assembly includes a second positioning block 381 and a pressing block 382 both mounted on the jaw base 38.

The pressing block 382 may be controllably moved toward or away from the second positioning block 381, so as to press the adaptor piece A3 onto the second positioning block 381 or release the pressing of the adaptor piece A3.

Specifically, in the embodiment, a plurality of third positioning grooves 3811 corresponding to the adaptor pieces A3 of each electrical core A1 of the electrical core group A4 one by one are formed on one side of the second positioning block 381 facing the pressing block 382. When the clamping jaw presss from both sides and gets electric core group A4, the second locating piece 381 inserts the switching piece A3 on each electric core A1 of electric core group A4 towards one side of electric core A1, and the switching piece A3 on each electric core A1 of electric core group A4 inserts to corresponding third constant head tank 3811 to utilize compact heap 382 to compress tightly switching piece A3 in third constant head tank 3811, in order to realize the location to switching piece A3 of each electric core A1 of electric core group A4.

Thus, when the cell pack A4 on the second support frame 33 needs to be transferred, firstly, the gripper seat 38 is controlled to move to the stacking station, and the gripper seat 38 is controlled to descend until the cell pack A4 on the second support frame 33 enters the clamping jaws. At this time, the clamping jaw is controlled to clamp the electric core group A4, the second positioning block 381 is inserted into one side of the electric core group A4, which is faced to the electric core A1, of the adaptor sheet A3 on each electric core A1 of the electric core group A4, each adaptor sheet A3 is located in the third positioning groove 3811 of the second positioning block 381, and the pressing block 382 is inserted into one side, which is deviated from the electric core A1, of each electric core A1 of the electric core group A4. Then, the pressing block 382 is controlled to move toward the second positioning block 381 until the adaptor piece A3 is pressed into the third positioning groove 3811 of the second positioning block 381, so as to position the adaptor piece A3. Then, the gripper base 38 is controlled to ascend, and the gripper base 38 is controlled to move to the assembling station, and the electric core group A4 is released to the assembling station. Alternatively, the clamping jaw may employ an electric jaw or a pneumatic jaw.

Further, the side of the pressing block 382 facing the second positioning block 381 has a first region 3821 and a second region 3822 located below the first region 3821. The first region 3821 is used to press the adaptor piece A3 onto the second positioning block 381, and the second region 3822 is used to fix the adaptor piece A3 by suction. Like this, the second region 3822 that utilizes compact heap 382 adsorbs fixedly to butt splicing piece A3, further improves butt splicing piece A3's positioning effect, improves positioning accuracy. It is understood that the second region 3822 may be provided with a suction hole communicating with an external air source or a suction cup to suck the contact piece A3.

In a specific embodiment, the second adaptor piece positioning assembly further includes a pressing driving piece 383, the pressing driving piece 383 is mounted on the jaw seat 38, and the pressing block 382 is mounted at a driving end of the pressing driving piece 383, so that the pressing driving piece 383 can drive the pressing block 382 to move toward or away from the second positioning block 381. Alternatively, the pressing actuator 383 may employ an air cylinder.

In particular embodiments, the second transfer mechanism further includes a second movement driving assembly (not shown) drivingly connected to the gripper seat 38 to drive the gripper seat 38 to move between the stacking station and the assembly station, and also to drive the gripper seat 38 up or down. It should be noted that the second moving driving assembly may adopt a well-established prior art, and is not limited herein as long as it can drive the jaw seat 38 to move between the stacking station and the assembling station, and also drive the jaw seat 38 to ascend or descend.

Referring to fig. 21 to 24, in an embodiment of the present invention, the assembling device 4 includes a third supporting frame 41 and a guiding block 42. The third support frame 41 has a third support position (not shown) for carrying the top cover B1 and the electric core group A4. The guide block 42 is installed on the third support frame 41, and a fourth positioning slot 421 is opened on one side facing the third support position. When the top cover B1 is supported on the third supporting position, one side of the guide block 42 having the fourth positioning groove 421 is attached to the top cover pin B2 of the top cover B1, so as to achieve the positioning effect on the top cover pin B2.

The top surface of the guide block 42 has a tab opening a communicating with the fourth positioning groove 421. When second transport mechanism transports electric core group A4 to the third support position of third support frame 41 on, switching piece A3 on each electric core A1 of electric core group A4 is inserted to fourth constant head tank 421 by inserted sheet opening a, thereby fourth constant head tank 421 plays the effect of carrying out the location to switching piece A3, and make and insert the top cap pin B2 of switching piece A3 and top cap in the fourth constant head tank 421 and laminate each other, so that follow-up welding the two, be favorable to promoting welding quality.

So, when the second transport mechanism drives electric core group A4 decline and with electric core group A4 release to the in-process on the top cap B1, first chamfer inclined plane 422 is in leading-in fourth constant head tank 421 with adaptor piece A3, avoids the unable phenomenon emergence that inserts fourth constant head tank 421 of adaptor piece A3.

In an embodiment, the inner wall of the fourth positioning groove 421 has a plurality of protrusions 423. The plurality of protrusions 423 are spaced apart from each other to partition the fourth positioning groove 421 into a plurality of sub positioning grooves 4210. When the second transfer mechanism transfers the battery cell group A4 to the third supporting position, the adaptor pieces A3 on the battery cells A1 of the battery cell group A4 are inserted into the plurality of positioning slots 4210 in a one-to-one correspondence manner. Thus, the fourth positioning groove 421 is divided into a plurality of sub positioning grooves 4210 by the plurality of protrusions 423, and the rotor plate A3 is positioned by each sub positioning groove 4210, which is beneficial to improving the positioning accuracy.

Further, the top end of each protrusion 423 has two second chamfer slopes 424 facing the two sub positioning grooves 4210 adjacent thereto. Thus, the two second chamfer slopes 424 at the top of the protruding portion 423 guide the adaptor pieces A3 of the two adjacent battery cells A1, so that the adaptor pieces A3 of the two battery cells A1 can be accurately inserted into the two sub positioning grooves 4210 at the two sides of the protruding portion 423, respectively.

When the second transfer mechanism transfers the cell group A4 to the third supporting position, the adaptor pieces A3 on the three cells A1 of the cell group A4 are inserted into the plurality of positioning grooves 4210 in a one-to-one correspondence manner.

Referring again to fig. 21-24, in some embodiments, the assembly device 4 further includes a first tab positioning assembly 43, and the first tab positioning assembly 43 includes a first tab driving assembly 431, a first tab mounting seat 432 and a first positioning tab 433. The first insert driving assembly 431 is installed on the third supporting frame 41 and is in driving connection with the first insert mounting seat 432. The first positioning insertion piece 433 is installed on the first insertion piece installation seat 432, so that the first positioning insertion piece 433 moves along with the first insertion piece installation seat 432.

The first insert driving assembly 431 is configured to controllably drive the first insert mounting seat 432 to move along the third horizontal direction Z, and drive the first positioning insert 433 to be inserted into a side of the top cover pin B2 of the top cover B1 away from the guide block 42.
