[0002] In the related art, when loading the battery cells, the battery cells need to be unpacked after packaging and placed in a material box, which is then sent to a sheet and paper picking station.

The air blowing is then stopped to separate the battery cells and separator paper. The battery cells are then arranged on a conveyor belt, the separator paper is placed in a collection box, and the battery cells are sent to the next process via the conveyor belt.

[0061] Embodiment 1

[0062] The photovoltaic manufacturing equipment in the embodiment of the present application is used to manufacture photovoltaic cell modules, which may include the material collection equipment 100 in the embodiment of the present application and downstream processing equipment arranged downstream of the material collection equipment 100, and the downstream processing equipment may include welding equipment, lamination equipment, etc.

[0063] See also Figure 1-Figure 5 The material picking device 100 in the embodiment of the present application may include a frame 10, a battery cell conveying mechanism 20, a blowing mechanism 30, a spacer paper recovery mechanism 40, a material box conveying assembly 50, a material picking mechanism 60 and a translation mechanism 70 in the embodiment of the present application.

[0064] The material taking mechanism 60 in the embodiment of the present application is used to suck the battery cell 201 and / or the separator paper 202 in the material box 200 to transfer the battery cell 201 and / or the separator paper 202. Specifically, Figure 5 As shown, a plurality of battery cells 201 and a plurality of separators 202 are alternately stacked in the material box 200, that is, the material box 200 is used to store the battery cells 201. In order to prevent the battery cells 201 from being scratched, a separator 202 is provided between two adjacent battery cells 201. The material taking device 100 is used to take out the battery cells 201 in the material box 200 and transport them to the downstream processing equipment.

[0065] See also Figure 3 The material picking mechanism 60 in the embodiment of the present application includes a mounting seat 61, a first lifting device 62, a suction cup bracket 63, at least one movable suction cup component 641 and a second lifting device 65.

[0066] The first lifting device 62 is installed at the bottom of the mounting seat 61, and the suction cup bracket 63 is connected to the first lifting device 62. The first lifting device 62 is used to drive the suction cup bracket 63 to move up and down relative to the mounting seat 61 along a first direction. Figure 5 As shown, the first direction is the stacking direction of the battery cells 201 and the separators 202 .

[0067] The movable suction cup component 641 is installed on the suction cup bracket 63. The movable suction cup component 641 is used to absorb the battery cell 201 and / or the spacer paper 202. The movable suction cup component 641 can be lifted up and down along the first direction relative to the suction cup bracket 63.

[0068] The second lifting device 65 is installed on the suction cup bracket 63 and connected to the movable suction cup component 641. The second lifting device 65 is used to drive the movable suction cup component 641 to move up and down along the first direction relative to the suction cup bracket 63, so that the battery cell 201 or the separator paper 202 sucked by the movable suction cup component 641 is bent in the first direction.

[0069] See also Figure 1 and Figure 2 The cell conveying mechanism 20, the blowing mechanism 30 and the spacer paper recovery mechanism 40 are all installed on the frame 10, and the cell conveying mechanism 20, the blowing mechanism 30 and the spacer paper recovery mechanism 40 are arranged at intervals along the second direction, and the second direction is perpendicular to the first direction;

[0070] The material box conveying assembly 50 is also installed on the frame 10. The material box conveying assembly 50 is used to convey the battery cells 201 and separators 202 in the material box 200 to the position of the blowing mechanism 30. The blowing mechanism 30 is used to blow air to the battery cells 201 and separators 202 in the material box 200 to separate the battery cells 201 and separators 202.

[0071] The mounting seat 61 of the picking mechanism 60 is movably mounted on the top of the frame 10 and can move relative to the frame 10 along the second direction. The translation mechanism 70 is mounted on the frame 10 and connected to the mounting seat 61 of the picking mechanism 60. The translation mechanism 70 is used to drive the mounting seat 61 to translate along the second direction to translate the battery cell 201 sucked by the picking mechanism 60 to above the battery cell conveying mechanism 20 and / or translate the spacer paper 202 sucked by the picking mechanism 60 to above the spacer paper recovery mechanism 40.

[0072] In the material picking mechanism 60, the material picking device 100 and the photovoltaic manufacturing device in the embodiment of the present application, the first lifting device 62 is installed at the bottom of the mounting seat 61, the suction cup bracket 63 is connected to the first lifting device 62, and the first lifting device 62 is used to drive the suction cup bracket 63 to move up and down relative to the mounting seat 61 along the first direction. The material picking mechanism 60 includes at least one movable suction cup component 641, the movable suction cup component 641 is installed on the suction cup bracket 63, and the movable suction cup component 641 is used to absorb the battery cell 201 or the separator 202. The second lifting device 65 is installed on the suction cup bracket 63 and connected to the movable suction cup component 641, and the second lifting device 65 is used to drive the movable suction cup component 641 to move up and down relative to the suction cup bracket 63 along the first direction, so that the battery cell 201 or the separator 202 sucked by the movable suction cup component 641 is bent in the first direction.

[0073] In this way, when taking materials, the first lifting device 62 can drive the movable suction cup component 641 to descend through the suction cup bracket 63 and contact with the battery cell 201 or the separator paper 202 for suction. After suction, the movable suction cup component 641 is driven by the second lifting device 65 to move upward in the first direction relative to the suction cup bracket 63, so that the battery cell 201 or the separator paper 202 is bent in the first direction. In this way, the contact surface of the battery cell 201 and the separator paper 202 will form a slight offset, making it easier to form an opening at the edge contact position of the two. The blowing mechanism 30 can make the opening larger by blowing, thereby reducing the static electricity between the battery cell 201 and the separator paper 202, making the two easier to separate, which can reduce paper or film taking failures, avoid the separator paper 202 being brought onto the battery cell conveying mechanism 20 when taking the film, and avoid the battery cell 201 being brought into the separator paper recovery mechanism 40 when taking the paper.

[0074] Specifically, in the present application, the first direction may be the Z-axis direction (i.e., the vertical direction) of the material taking device 100, and the second direction may be the X-axis direction or the Y-axis direction of the material taking device 100, and the two are perpendicular to each other. The mounting seat 61 may be slidably connected to the frame 10, and the translation mechanism 70 may be a linear drive module, such as a linear cylinder, a screw nut drive mechanism, etc., which is not specifically limited here.

[0075] It is not difficult to understand that in the embodiment of the present application, when the material picking device 100 is in operation, the packaged battery cell 201 can be unpacked and placed in the material box 200, and the material box 200 is conveyed to the cell picking position (that is, conveyed to the blowing position of the blowing mechanism 30) by the material box conveying assembly 50, and then, the first lifting device 62 drives the suction cup bracket 63 to descend and enables the movable suction cup component 641 to adsorb the battery cell 201 and adsorb the battery cell 201, and at the same time, the blowing mechanism 30 is opened, and then the second lifting device 65 drives the movable suction cup component 641 to rise, so that the battery cell 201 is bent in the first direction, thereby causing the contact surface of the battery cell 201 and the separator paper 202 to form a slight offset, so that the battery cell 201 and the separator paper 202 are more easily formed. At the same time, under the action of blowing, the opening is enlarged, so that the static electricity between the battery cell 201 and the separator 202 is weakened, and the separator 202 is easier to separate from the battery cell 201, which can reduce the failure of taking the cell. After the separator 202 and the battery cell 201 are separated, the blowing is stopped, and the second lifting device 65 is lowered to the initial state, so that the battery cell 201 is restored to a flat state. Then, the first lifting device 62 rises a certain distance as a whole and drives the entire material taking mechanism 60 through the translation mechanism 70 to drive the battery cell 201 to translate along the second direction to the top of the battery cell conveying mechanism 20. Then, the first lifting device 62 is lowered, and the movable suction cup component 641 releases the battery cell 201 to place the battery cell 201 on the battery cell conveying mechanism 20, so as to convey the battery cell 201 into the downstream equipment. Subsequently, in the process of taking the separator 202, the principle of taking the separator 202 is the same as the principle of taking the battery cell 201, and this cycle is repeated to achieve the complete removal of the battery cell 201 and the separator 202. It can be understood that the difference between taking out the separator paper 202 and taking out the battery cell 201 is that when taking out the paper, the second lifting device 65 drives the movable suction cup component 641 to bend the separator paper 202 and transport the separator paper 202 to the separator paper recovery mechanism 40.

[0076] It is understood that, in some embodiments, one side of the separator 202 may be smooth and the other side may be rough, with the smooth side facing the back side of the battery cell 201 and the rough side facing the front side of the next battery cell 201. In this case, the static electricity between the rough side and the battery cell 201 is relatively weak, and it is not necessary to go through the bending step, that is, in this case, when taking the separator 202, it is not necessary to bend the separator 202 through the second lifting device 65.

[0077] In some embodiments, both sides of the separator 202 may be smooth. In this case, the separator 202 also needs to be bent by the second lifting device 65. That is to say, as a possible way, in the present application, whether the separator 202 needs to be bent by the second lifting device 65 may depend on the type of the separator 202.

[0078] Of course, if one side of the separator paper 202 is smooth and the other side is rough, considering that the front and back sides of the separator paper 202 may be placed upside down when packaging the battery cell 201, in the present application it is preferred to bend both the separator paper 202 and the battery cell 201 by the second lifting device 65 when taking them out.

[0079] In some embodiments, the first lifting device 62 may include a first cylinder, and the suction cup bracket 63 may be fixedly connected to the piston rod of the first cylinder, so that the suction cup bracket 63 is driven to move up and down along the first direction by the piston rod. Similarly, in some embodiments, the second lifting device 65 may include a second cylinder, and the movable suction cup component 641 is fixedly connected to the piston rod of the second cylinder, so that the movable suction cup component 641 is driven to move up and down relative to the suction cup bracket 63 along the first direction by the piston rod.

[0080] Embodiment 2

[0081] See also Figure 1 and Figure 2 In some embodiments, there may be two material picking mechanisms 60, which are spaced apart along the second direction. One of the material picking mechanisms 60 is used to suck the battery cell 201 in the material box 200 and translate the battery cell 201 along the second direction to above the battery cell conveying mechanism 20, and the other material picking mechanism 60 is used to suck the separator 202 in the material box 200 and translate the separator 202 along the second direction to above the separator recovery mechanism 40.

[0082] In this way, by providing two material taking mechanisms 60 to take and place the battery cell 201 and the separator paper 202 respectively, the material taking efficiency can be improved.

[0083] Specifically, in such an embodiment, the mounting bases 61 of the two picking mechanisms 60 are both slidably connected to the frame 10, and two translation mechanisms 70 can be used to separately drive the picking mechanisms 60, wherein the picking mechanism 60 for picking up the battery cell 201 translates between the battery cell conveying mechanism 20 and the picking position, and the picking mechanism 60 for picking up the spacer paper 202 translates between the spacer paper recovery mechanism 40 and the picking position, and the two do not interfere with each other.

[0084] Of course, it is understandable that without considering the material picking efficiency, only one material picking mechanism 60 can be set. In this case, the material picking mechanism 60 can move back and forth between the battery cell conveying mechanism 20 and the separator paper recovery mechanism 40 to respectively pick up and place the battery cell 201 and the separator paper 202.

[0086] See also Figure 1 , Figure 2 as well as Figure 5-Figure 7In some embodiments, the material box conveying assembly 50 may include a material box conveying mechanism 51 and a lifting mechanism 52, the lifting mechanism 52 is located below the material box conveying mechanism 51, the material box 200 may include a material box body 203 and a support plate 204 arranged in the material box body 203, the battery cells 201 and the separator paper 202 are stacked on the support plate 204, the material box conveying mechanism 51 is used to convey the material box 200 to the bottom of the blowing mechanism 30, and the lifting mechanism 52 is used to drive the support plate 204 to rise and fall relative to the material box body 203 along the first direction to lift the battery cells 201 and the separator paper 202 to the position where the blowing mechanism 30 is located.

[0087] In this way, the material box conveying mechanism 51 can convey the material box 200 to the right position, and the setting of the lifting mechanism 52 can lift the battery cells 201 and the separator paper 202 one by one to the blowing position of the blowing mechanism 30 to realize the material removal one by one.

[0088] Specifically, in such an embodiment, in the initial position, the lifting mechanism 52 can lift the first battery cell 201 to the blowing position of the blowing mechanism 30, thereby removing the first battery cell 201 and the first separator 202. Subsequently, the lifting mechanism 52 rises a certain distance and lifts the next battery cell 201 to the blowing position, and this cycle is repeated until the last battery cell 201 and separator 202 are removed.

[0089] Furthermore, if Figure 1 and Figure 2 as well as Figure 6-Figure 7 As shown, in such an embodiment, the lifting mechanism 52 may include a linear lifting module 521 and a lifting member 522, a first through hole 2031 may be formed at the bottom of the material box body 203, the linear lifting module 521 is installed on the frame 10, and the lifting member 522 is connected to the linear lifting module 521, and the linear lifting module 521 is connected and used to drive the lifting member 522 to move up and down along the first direction, so that the lifting member 522 passes through the first through hole 2031 and drives the support plate 204 to move up and down along the first direction.

[0090] Thus, by opening the first through hole 2031 on the material box body 203 , the lifting member 522 can be smoothly extended into the material box body 203 to lift the support plate 204 and the battery cells 201 and the separator paper 202 on the support plate 204 to the blowing position of the blowing mechanism 30 .

[0091] Specifically, in such an embodiment, the material box conveying mechanism 51 can first convey the material box 200 as a whole to the bottom of the blowing mechanism 30, and then the lifting mechanism 52 is started, and the lifting member 522 extends into the material box body 203 through the first through hole 2031 on the material box body 203 to contact the support plate 204, and lifts the support plate 204 and the battery cells 201 and separator paper 202 on the support plate 204 to the blowing position of the blowing mechanism 30.

[0092] Embodiment 4

[0093] See also Figure 7 In some embodiments, the material box conveying mechanism 51 may include a first pulley assembly 511 and a second pulley assembly 512 that are relatively spaced apart, the first pulley assembly 511 and the second pulley assembly 512 are used to carry and convey the material box 200, the first through hole 2031 corresponds to the area between the first pulley assembly 511 and the second pulley assembly 512, and the lifting member 522 is located between the first pulley assembly 511 and the second pulley assembly 512.

[0094] In this way, by configuring the material box conveying mechanism 51 to have two pulley assemblies that are relatively spaced apart, the lifting member 522 can be disposed between the two pulley assemblies so that the lifting member 522 can pass through the area between the two pulley assemblies during the lifting process, thereby lifting the support plate 204. The structure is relatively simple and compact, and interference between the lifting member 522 and the material box conveying mechanism 51 can also be avoided.

[0095] Specifically, in such an embodiment, the material box conveying mechanism 51 can be a conveyor belt conveying mechanism, and the first pulley assembly 511 and the second pulley assembly 512 both include pulleys and belts. The two pulley assemblies can be synchronously driven by a motor. When feeding, the material box 200 can be placed on two belts, and the first through hole 2031 is aligned with the area between the two pulley assemblies. The two pulley assemblies can convey the material box 200 to between the lifting mechanism 52 and the blowing mechanism 30, and then the lifting mechanism 52 is started, and the lifting member 522 passes through the area between the two pulley assemblies and extends into the first through hole 2031 to lift the pallet 204.

[0096] Embodiment 5

[0097] See also Figure 5-Figure 7 In some embodiments, the blowing mechanism 30 may include a frame 31 and a blowing nozzle 32 installed on the frame 31, the air outlet of the blowing nozzle 32 faces the inside of the frame 31, and a second through hole 311 is formed at the bottom of the frame 31. The second through hole 311 is used for the lifting member 522, the support plate 204, and the battery cell 201 and the separator paper 202 on the support plate 204 to pass through and enter the frame 31, so that the gas blown out of the blowing nozzle 32 is blown toward the battery cell 201 and the separator paper 202.

[0098] In this way, the lifting member 522, the first through hole 2031 and the second through hole 311 are cleverly designed, so that the lifting member 522 can lift the support plate 204 through the first through hole 2031, and then the support plate 204 and the battery cell 201 and the separator 202 on the support plate 204 enter the frame 31 of the blowing mechanism 30 through the second through hole 311, so that the gas blown out by the blowing nozzle 32 can be smoothly blown to the battery cell 201 and the separator 202. At the same time, such a design can make the various structures of the entire device more compact, and the setting of the frame 31 can also limit the battery cell 201 to prevent the battery cell 201 from shaking and deflecting greatly in the frame 31.

[0099] Specifically, in such an embodiment, when the material box 200 is conveyed between the blowing mechanism 30 and the lifting member 522, the second through hole 311 on the frame 31, the first through hole 2031 on the material box body 203 and the lifting member 522 correspond to each other in the first direction, and when the lifting member 522 rises, it extends into the first through hole 2031 to support the support plate 204 and drive the support plate 204 to rise, and the support plate 204 and the battery cells 201 and the separator paper 202 on the support plate 204 pass through the second through hole 311 into the frame 31 of the blowing mechanism 30, so that the airflow of the blowing nozzle 32 can be blown to the battery cells 201 and the separator paper 202.

[0100] Embodiment 6

[0101] See also Figure 1 and Figure 7 In some embodiments, the material box conveying mechanism 51 conveys the material box 200 along the third direction, and the battery cell conveying mechanism 20 conveys the battery cells 201 along the third direction. The first direction and the second direction are perpendicular to the third direction.

[0102] In this way, the material box conveying mechanism 51 and the battery cell conveying mechanism 20 are both arranged along the third direction, and the battery cell conveying mechanism 20, the blowing mechanism 30 and the spacer paper recovery mechanism 40 are arranged along the second direction, so that the structure of the entire material picking equipment 100 can be more compact and the space occupied by the material picking equipment 100 can be reduced.

[0103] Specifically, in such an embodiment, the first direction is the Z-axis direction of the material retrieving device 100 , and the second direction and the third direction are the X-direction and the Y-direction of the material retrieving device 100 , respectively.

[0104] Embodiment 7

[0105] See also Figure 3 , Figure 8 and Fig. 9In some embodiments, the suction cup bracket 63 may include a mounting plate 631 and a mounting protrusion 632 protruding from the mounting plate 631 toward the side of the mounting seat 61, the mounting protrusion 632 forms a cavity 6321, the second lifting device 65 may include a driving body 651 and a movable part 652, the driving body 651 is installed on the mounting protrusion 632, the movable part 652 passes through the mounting protrusion 632 and extends into the cavity 6321, one end of the movable suction cup component 641 passes through the mounting plate 631 and extends into the cavity 6321 and is fixedly connected to the movable part 652, the driving body 651 is used to drive the movable suction cup component 641 to move up and down along the first direction through the movable part 652.

[0106] In this way, by setting a mounting protrusion 632 on the suction cup bracket 63, the second lifting device 65 can be stably installed, and the cavity 6321 formed on the mounting protrusion 632 can enable the movable part 652 to move freely up and down in the cavity 6321 along the first direction relative to the mounting protrusion 632, so as to drive the movable suction cup component 641 to move up and down along the first direction.

[0107] Specifically, in such an embodiment, when the second lifting device 65 is a cylinder, the driving body 651 is equivalent to the cylinder body, and the movable member 652 is equivalent to the piston rod, which can be fixedly connected with the movable suction cup component 641 in the cavity 6321 of the mounting protrusion 632. The connection between the movable member 652 and the movable suction cup component 641 can be threaded connection, clamping connection, welding, etc., which is not specifically limited here, and it is preferably a detachable connection.

[0108] Embodiment 8

[0109] See also Figure 3 and Fig. 9 In some embodiments, the material picking mechanism 60 may further include at least one fixed suction cup component 642 , which is fixedly mounted on the suction cup bracket 63 , and is used to absorb the battery cell 201 or the spacer paper 202 together with the movable suction cup component 641 .

[0110] In this way, after sucking the battery cell 201 or the separator 202, the setting of the fixed suction cup component 642 can keep most of the position of the battery cell 201 or the separator 202 unchanged, and only the part driven by the second lifting device 65 is bent, so that the contact surface between the battery cell 201 and the separator 202 is slightly offset.

[0111] Furthermore, if Figure 3As shown, in some embodiments, the material picking mechanism 60 may include two fixed suction cup components 642 and two movable suction cup components 641, the two fixed suction cup components 642 and the two movable suction cup components 641 are distributed in a rectangular shape, the two movable suction cup components 641 are diagonally arranged, and the two fixed suction cup components 642 are diagonally arranged.

[0112] In this way, the two fixed suction cup components 642 and the two movable suction cups 644 are set diagonally, so that the contact surface between the battery cell 201 and the separator paper 202 can be slightly offset at the two diagonal edges, and the airflow of the blowing mechanism 30 can blow toward the offset position along both sides, thereby accelerating the reduction of static electricity between the separator paper 202 and the battery cell 201, so that the battery cell 201 can be separated from the separator paper 202 quickly and smoothly.

[0113] Of course, it is understandable that in some embodiments, the material picking mechanism 60 may also include only one movable suction cup component 641, and it is only necessary that the movable suction cup component 641 can smoothly bend the battery cell 201 or the separator paper 202 to reduce the static electricity between the battery cell 201 and the separator paper 202.

[0114] For further information, see Figure 8 and Fig. 9 In such an embodiment, the suction cup bracket 63 may include a first cross arm 633 and a second cross arm 634 that are cross-arranged, a fixing hole 635 is provided at the intersection of the first cross arm 633 and the second cross arm 634, the first lifting device 62 is fixedly connected to the suction cup bracket 63 through the fixing hole 635, and fixed suction cup components 642 are respectively installed at both ends of the first cross arm 633, and movable suction cup components 641 are respectively installed at both ends of the second cross arm 634.

[0115] In this way, by forming a suction cup bracket 63 with two cross arms, the use of materials can be reduced and the cost can be lowered. At the same time, by respectively installing a fixed suction cup component 642 and a movable suction cup component 641 at both ends of the two cross arms, the two movable suction cup components 641 can bend the two diagonals of the battery cell 201 or the separator paper 202. The blowing mechanism 30 blows air from both sides, which can speed up the separation speed of the battery cell 201 and the separator paper 202.

[0116] Specifically, in such an embodiment, the mounting plate of the suction cup bracket 63 includes a first cross arm 633 and a second cross arm 634 , the mounting protrusions 632 may be respectively located at both ends of the second cross arm 634 , and the second lifting device 65 is installed on the mounting protrusions 632 at both ends of the second cross arm 624 .

[0117] Of course, see Fig.10In some embodiments, the entire material taking mechanism 60 may not include the fixed suction cup component 642, but only include a movable suction cup component 641. In this case, Fig.10 As shown, a first abutting portion 636 is convexly provided on the side of the suction cup bracket 63 away from the mounting seat 61, and the first abutting portion 636 can be located on both sides of a single movable suction cup component 641 or arranged around the movable suction cup component 641. After the movable suction cup component 641 absorbs the battery cell 201 or the separator 202, the second lifting device 65 drives the movable suction cup component 641 and the absorbed battery cell 201 or the separator 202 to move upward, and the first abutting portion 636 abuts the battery cell 201 or the separator 202 to bend the battery cell 201 or the separator 202 in the first direction.

[0118] In addition, in some embodiments, the entire material taking mechanism 60 may not be provided with a fixed suction cup component 642, but may be provided with a plurality of movable suction cup components 641. In such a case, Fig.11 As shown, taking two movable suction cup components 641 as an example, in such an example, a second supporting portion 637 may be protruded on the side of the suction cup bracket 63 away from the mounting seat 61, and the second supporting portion 637 is located between the two movable suction cup components 641. After the movable suction cup component 641 adsorbs the battery cell 201 or the spacer paper 202, the second lifting device 65 drives the movable suction cup component 641 and the adsorbed battery cell 201 or the spacer paper 202 to move upward, and the second supporting portion 637 abuts the battery cell 201 or the spacer paper 202 and causes the battery cell 201 or the spacer paper 202 to bend in the first direction.

[0119] It can be understood that, in some embodiments, if only two or more movable suction cup components 641 are provided without a fixed suction cup component 642, the second supporting portion 637 may not be provided on the suction cup bracket 63 to support the battery cell 201 or the spacer paper 202. Instead, the battery cell 201 or the spacer paper 202 may be bent by controlling the lifting height of multiple movable suction cup components 641. For example, taking two movable suction cup components 641 as an example, the two movable suction cup components 641 may first be synchronously descended to adsorb the battery cell 201 or the spacer paper 202. Then, in a possible embodiment, one of the movable suction cup components 641 may be kept stationary, and the other movable suction cup component 641 may move upward under the drive of the second lifting device 65, thereby driving the battery cell 201 or the spacer paper 202 to bend. In another possible embodiment, the lifting height of the upward movement of the two movable suction cup components 641 may be controlled so that the two movable suction cup components 641 have a height difference in the first direction, thereby bending the battery cell 201 or the spacer paper 202. No specific limitation is made here.

[0120] In summary, in the present application, the material picking mechanism 60 may have only one movable suction cup component 641 or multiple movable suction cup components 641 , or may have both a fixed suction cup component 642 and a movable suction cup component 641 .

[0121] Embodiment 9

[0122] See also Fig.10 In some embodiments, the movable suction cup component 641 may include an air suction nozzle 643, a suction cup 644 and an adsorbent 645. The air suction nozzle 643 is installed on the suction cup bracket 63, the suction cup 644 is installed on the air suction nozzle 643, the adsorbent 645 is arranged around the suction cup 644, and the bottom of the adsorbent 645 protrudes from the bottom of the suction cup 644, and the adsorbent 645 is formed with a hole structure (not shown in the figure).

[0123] In this way, by surrounding the suction cup 644 with the adsorbent 645 , the movable suction cup component 641 contacts the battery cell 201 and the separator 202 through the adsorbent 645 , and the hole structure in the adsorbent 645 can adsorb impurities to prevent the impurities from contaminating the battery cell 201 .

[0124] It is understood that in the related art, the suction cup is usually made of silicone or soft rubber. After long-term use, impurities will adhere to the surface and cause contamination of the battery cell, and there will be defects such as suction cup marks on the surface of the battery cell. In this embodiment, by surrounding the suction cup 644 with an adsorbent 645, the movable suction cup component 641 contacts the battery cell 201 through the adsorbent 645. When sucking the separator 202 or the battery cell 201, impurities will be adsorbed in the hole structure of the adsorbent 645 to avoid contamination of the battery cell 201. In such an embodiment, the adsorbent 645 can be a foam sponge.

[0125] Specifically, in such an embodiment, in the movable suction cup component 641, the suction nozzle 643 is movably connected to the suction cup bracket 63 and connected to the second lifting device 65, and the second lifting device 65 is used to drive the suction nozzle 643 to move up and down along the first direction relative to the suction cup bracket 63, thereby realizing the up and down movement of the entire movable suction cup component 641. In the fixed suction cup component 642, the suction nozzle 643 of the fixed suction cup component 642 is fixedly connected to the suction cup bracket 63.

[0126] See also Fig.10 In some embodiments, the adsorbent 645 is formed with a mounting hole 6451 that cooperates with the suction cup 644 , a protrusion 6441 is formed on the outer side of the suction cup 644 , and a groove 6452 that cooperates with the protrusion 6441 is formed on the hole wall of the mounting hole 6451 .

[0127] In this way, the adsorption component 645 can be mounted on the suction cup 644 through the mounting hole 6451 , and the matching structure of the protrusion 6441 and the groove 6452 can prevent the adsorption component 645 from falling off the suction cup 644 , thereby ensuring the installation stability of the adsorption component 645 .

[0128] See also Fig.10 In some embodiments, the protrusion height H of the bottom of the adsorption member 645 from the bottom of the suction cup 644 is 0.2 mm-3 mm.

[0129] In this way, it can be avoided that the adsorption member 645 protrudes too high from the bottom of the suction cup 644, resulting in too weak adsorption force of the movable suction cup component 641, and it can also be avoided that the adsorption member 645 protrudes too low from the bottom of the suction cup 644, resulting in external impurities easily contaminating the suction cup 644 and causing contamination of the battery cell 201.

[0130] Specifically, in such an embodiment, the height H of the bottom of the adsorption member 645 protruding from the bottom of the suction cup 644 may be, for example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3mm or any value between 0.2mm-3mm, and is not limited here.

[0131] In some embodiments, the hole diameter of the hole structure may be 0.1 mm-2 mm.

[0132] In this way, it can be avoided that the hole is too large so that external impurities are directly adsorbed onto the suction cup 644 through the hole, and it can also be avoided that the hole is too small so that the function of adsorbing impurities cannot be achieved.

[0133] Specifically, in such an embodiment, the hole diameter of the hole structure may be, for example, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 9mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm, 2mm or any value between 0.1mm-2mm, without limitation herein.

[0134] In addition, in the present application, when the material picking mechanism 60 includes a fixed suction cup component 642, the structure of the fixed suction cup component 642 is the same as the structure of the movable suction cup component 641, and the only difference is that the suction nozzle of the movable suction cup component 641 is movably mounted on the suction cup bracket 63 and can be raised and lowered in a first direction relative to the suction cup bracket 63, while the suction nozzle of the fixed suction cup component 642 is fixedly mounted on the suction cup bracket 63.
