Description

Technical Field

[0001] This invention relates to the field of lithium battery manufacturing technology, and in particular to a mechanism, method, and feeding device for identifying the orientation of connector pieces. Background Technology

[0002] Lithium-ion batteries, as a clean and green energy source, have advantages such as high operating voltage, high specific energy, and long cycle life, and are currently widely used in energy storage systems, power tools, consumer electronics, and electric vehicles. With the development of lithium-ion batteries, the market has higher requirements for their performance. Existing lithium batteries require connecting tabs to the top cover during assembly to improve the connection strength between the top cover and the cell. However, in the current battery assembly process, manual feeding easily leads to incorrect orientation or orientation of the connecting tabs. Furthermore, because existing feeding devices cannot recognize the orientation or orientation of the connecting tabs, automated feeding cannot be achieved, resulting in low automation. Summary of the Invention

[0051] If the first vacuum level value is greater than the second vacuum level value, then the notch of the connecting piece faces the second identification component;

[0052] If the first vacuum level value is less than the second vacuum level value, the notch of the connecting piece faces the first identification component;

[0053] Alternatively, the first vacuum degree value and the second vacuum degree value can be compared with the vacuum degree threshold.

[0054] If the first vacuum degree value is equal to the vacuum degree threshold or the second vacuum degree value is less than the vacuum degree threshold, then the notch of the connecting piece faces the second identification component;

[0055] If the first vacuum level value is less than the vacuum level threshold or the second vacuum level value is equal to the vacuum level threshold, then the notch of the connecting piece faces the first identification component.

[0056] In conjunction with the third aspect, one end of the connecting piece along its own thickness direction has a protrusion;

[0057] The method for determining the orientation of the connecting piece based on the pressure value includes:

[0058] Compare the pressure value with the pressure threshold;

[0059] If the pressure value is greater than the pressure threshold, the protrusion of the connecting piece faces the pressure sensor;

[0064] When the orientation of the protrusion of the connecting piece does not conform to the setting, but the orientation of the notch does conform to the setting, the connecting piece is moved to the adjustment position by the linear module;

[0065] When the orientation of the protrusion of the connecting piece conforms to the setting, but the orientation of the notch does not conform to the setting, the connecting piece is rotated by the rotary cylinder to adjust its position. After the adjustment is completed, the connecting piece is moved to the processing station by the linear module.

[0066] When the orientation of the protrusion and the notch of the connecting piece meets the set requirements, the connecting piece is moved to the processing station by the linear module.

Detailed Implementation

[0083] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0084] The specific implementation manners of the present application are further elaborated through the following embodiments:

[0085] Please refer to Figure 1 , an embodiment of the present application provides a mechanism for identifying the direction of the connecting piece 400, including a moving component 100 and an identifying component 200 that are connected to each other.

[0086] Please refer to Figure 2 , in the embodiment of the present application, the identifying component 200 includes a rotary cylinder 210, a connecting platform 250, a first identifying member 220, a second identifying member 230, and a third identifying member 240. The end of the rotary cylinder 210 is fixedly connected to the moving component 100, and the output shaft of the rotary cylinder 210 is fixedly connected to the connecting platform 250. The first identifying member 220, the second identifying member 230, and the third identifying member 240 are all connected to the connecting platform 250. Among them, the second identifying member 230 is arranged side by side with the first identifying member 220 at an interval. The third identifying member 240 is located between the first identifying member 220 and the second identifying member 230. The first identifying member 220 and the second identifying member 230 are used to identify the orientation of the connecting piece 400, and the third identifying member 240 is used to identify the front and back of the connecting piece 400.

[0087] It can be understood that the moving component 100 drives the rotary cylinder 210 to move back and forth, so that the rotary cylinder 210 can带动 the connecting platform 250 and the first identifying member 220, the second identifying member 230, and the third identifying member 240 that are connected to the connecting platform 250 to move back and forth together. And the rotary cylinder 210 itself drives the connecting platform 250 to rotate. Therefore, when the orientation of the connecting piece 400 identified by the first identifying member 220 and the second identifying member 230 does not meet the expectation, it can be rotated by a certain angle through the rotary cylinder 210 so that the orientation of the connecting piece 400 is the same as the set orientation. Similarly, when the third identifying member 240 identifies that the upward surface of the connecting piece 400 does not conform to the setting, the connecting piece 400 at the bottom can be moved to other workstations by the moving component 100.

[0088] 请参阅 Figures 4-7 , in the embodiment of the present application, the mechanism has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. Along the second direction Y, the connecting piece 400 has a tail 440 and a headpiece 430 that are connected to each other, and the headpiece 430 and the tail 440 are on the same horizontal plane. Along the first direction X, the tail 440 has a first width L1, and the headpiece 430 has a second width L2, and L1 and L2 satisfy 1 < L1 / L2 ≤ 2. As Figure 4 and Figure 5As shown, the tail 440 has a notch 410, one end of which extends along the second direction Y to near the junction of the tail 440 and the head 430, and the other end of which extends in the opposite direction of the second direction Y, dividing the tail 440 into two parts. Figure 6 and Figure 7 As shown, the connecting piece 400 has a front and a back side along its own thickness direction. A protrusion 420 is provided at the head 430 position on the back side of the connecting piece 400. The protrusion 420 protrudes along the thickness direction of the connecting piece 400, i.e., the third direction Z. A plastic part is covered at the head 430 position on the front side of the connecting piece 400. The plastic part and the tail 440 of the connecting piece 400 form a step. The height of the protrusion 420 is higher than the height of the step formed by the plastic part.

[0089] Please see Figure 3 In this embodiment, the first identification component 220 includes a first suction nozzle 221, a second suction nozzle 222, a third suction nozzle 223, and a first vacuum suction tube 224. The first suction nozzle 221, the second suction nozzle 222, and the third suction nozzle 223 are spaced apart on the side of the connecting platform 250 away from the rotary cylinder 210, and the first vacuum suction tube 224 is located on the side of the connecting platform 250 away from the first suction nozzle 221. The first vacuum suction tube 224 communicates with the first suction nozzle 221, the second suction nozzle 222, and the third suction nozzle 223, which are arranged in a triangular pattern along a first X-direction. It is understood that suction cups are provided at the openings of the first suction nozzle 221, the second suction nozzle 222, and the third suction nozzle 223 away from the connecting platform 250. When pressed downwards, the suction cups spread outwards, thus achieving a sealing effect. Therefore, the three suction nozzles arranged in a triangle do not interfere with each other when pressed, and also reduce the size of the bottom surface of the connecting platform 250. The same end of the first suction nozzle 221, the second suction nozzle 222, and the third suction nozzle 223 converges inside the connecting platform 250 and connects to the first vacuum suction tube 224. The other end of the first vacuum suction tube 224 is connected to a vacuum pump. When the vacuum pump is started, it extracts the air from the first suction nozzle 221, the second suction nozzle 222, the third suction nozzle 223 and the first vacuum suction tube 224, and records the vacuum level value in the first vacuum suction tube 224 under this state.

[0090] Please continue reading. Figure 3In this embodiment, the second identification component 230 includes a fourth suction nozzle 231, a fifth suction nozzle 232, a sixth suction nozzle 233, and a second vacuum suction tube 234. The fourth suction nozzle 231, the fifth suction nozzle 232, and the sixth suction nozzle 233 are spaced apart on the side of the connecting platform 250 away from the rotary cylinder 210, and the second vacuum suction tube 234 is located on the side of the connecting platform 250 away from the fourth suction nozzle 231. The second vacuum suction tube 234 communicates with the fourth suction nozzle 231, the fifth suction nozzle 232, and the sixth suction nozzle 233, which are arranged in a triangular pattern along the first direction X. It is conceivable that suction cups are also provided at the openings of the fourth suction nozzle 231, the fifth suction nozzle 232, and the sixth suction nozzle 233, and are symmetrically arranged with the first suction nozzle 221, the second suction nozzle 222, and the third suction nozzle 223 about the center line of the connecting platform 250 along the first direction X. Therefore, the three suction nozzles will not interfere with each other when pressed. The same end of the fourth suction nozzle 231, the fifth suction nozzle 232, and the sixth suction nozzle 233 is connected to the second vacuum suction tube 234 inside the connecting platform 250. The second vacuum suction tube 234 is also connected to the vacuum pump. When the vacuum pump is started, it extracts the air from the fourth suction nozzle 231, the fifth suction nozzle 232, the sixth suction nozzle 233, and the second vacuum suction tube 234, and simultaneously records the vacuum level value inside the second vacuum suction tube 234.

[0091] It should be noted that when the notch 410 on the connecting piece 400 faces the first identification component 220, the notch 410 is directly opposite to at least one of the first suction nozzles 221, 222, and 223. When the notch 410 on the connecting piece 400 faces the second identification component 230, the notch 410 is directly opposite to at least one of the fourth suction nozzles 231, 232, and 233. Therefore, at least one of the three suction nozzles opposite the notch 410 is not in contact with the connecting piece 400, which results in a different vacuum pump reading when evacuating air from two vacuum tubes compared to when all three suction nozzles are in contact.

[0092] It is conceivable that, in the embodiments of this application, the cooperation between the first suction nozzle 221, the second suction nozzle 222, the third suction nozzle 223 and the first vacuum suction tube 224, and the cooperation between the fourth suction nozzle 231, the fifth suction nozzle 232, the sixth suction nozzle 233 and the second vacuum suction tube 234, are not merely for identifying the connecting piece 400. After vacuuming, the two sets of nozzles can also serve to connect and fix the connecting piece 400. When the vacuum pump removes the air between the six nozzles and the vacuum suction tube, the connecting piece 400 will be fixed to the nozzles due to atmospheric pressure. Therefore, the six nozzles can also serve as transport components for the connecting piece 400 to fix it. Nevertheless, in some embodiments, the cooperation between the nozzles and the vacuum suction tube can be limited to only one set, i.e., only the combination of the first suction nozzle 221, the second suction nozzle 222, the third suction nozzle 223 and the first vacuum suction tube 224, or only the combination of the fourth suction nozzle 231, the fifth suction nozzle 232, the sixth suction nozzle 233 and the second vacuum suction tube 234. It is foreseeable that when there is only one set, the cooperation between the suction nozzle and the vacuum tube can also be used to identify and move the connecting piece 400. It should be noted that the vacuum referred to in this application is not a complete absence of air, but an environment that is relatively close to a vacuum, which allows at least three suction nozzles to lift and move the connecting piece 400 after the air is removed.

[0093] Please see Figure 2In this embodiment, the third identification component 240 includes a pressure sensor 241 and a spring 242. The pressure sensor 241 is fixed to the connecting platform 250, and the spring 242 is fixedly connected to the end of the pressure sensor 241 away from the rotary cylinder 210. When the spring 242 is compressed and contracts, the pressure on the spring 242 can be received by the pressure sensor 241. It can be understood that the position of the spring 242 is opposite to the position of the protrusion 420 on the connecting piece 400 in the vertical direction. Therefore, when the back of the connecting piece 400 is facing upward, that is, when the protrusion 420 is facing upward, the protrusion 420 will abut against the spring 242 and cause it to contract. When the front of the connecting piece 400 is facing upward, since there is no protrusion 420 on the front, the spring 242 is suspended and will not contact the connecting piece 400. Therefore, the reading obtained by the pressure sensor 241 is 0. Compared to the pressure exerted on spring 242 in the two instances, when spring 242 contacts protrusion 420, the pressure exerted on spring 242 is greater than 0. Therefore, the value of pressure sensor 241 can be used to determine whether the connecting piece 400 is facing upwards (back side) or upwards (right side). It should be noted that when the connecting piece 400 is facing upwards, there may be slight contact between spring 242 and connecting piece 400, resulting in a smaller reading on pressure sensor 241. Additionally, spring 242 itself may be subject to interference during movement, causing slight fluctuations in the reading obtained by pressure sensor 241. However, the readings obtained from such interference and contact are both small and can be considered as zero.

[0094] Please see Figure 1In this embodiment, the moving component 100 includes a linear module 110, a moving block 120, a moving cylinder 130, and a connecting block 140. The moving block 120 is slidably connected to the linear module 110. The moving cylinder 130 is fixedly connected to the moving block 120. One end of the connecting block 140 is fixedly connected to the output shaft of the moving cylinder 130, and the other end is fixedly connected to the rotary cylinder 210. It can be understood that the linear module 110 drives the moving cylinder 130 to perform horizontal reciprocating motion. Since the bottom of the moving cylinder 130 is connected to the identification component 200, it is equivalent to the linear module 110 driving the entire identification component 200 to perform horizontal reciprocating motion. After the connecting piece 400 is identified, it is moved to different workstations for further processing according to the settings. The moving cylinder 130 is connected to the identification component 200 through the moving block 120; therefore, it can be assumed that the moving cylinder 130 drives the identification component 200 to perform vertical reciprocating motion. Therefore, when it is necessary to identify the connecting piece 400, the moving cylinder 130 extends to press the identification component 200 downward, so that the identification component 200 can contact the connecting piece 400. After the vacuum pump finishes pumping, the identification component 200 picks up the connecting piece 400, and the moving cylinder 130 retracts upward to lift the connecting piece 400. During this process, the position of the connecting piece 400 is judged, and then the linear module 110 moves it to the corresponding workstation according to the position of the connecting piece 400.

[0095] Please see Figure 8 This application provides a feeding device, including the mechanism for identifying the direction of the connecting piece 400 as described above, and a storage frame 300. The storage frame 300 is located on the side of the mechanism for identifying the direction of the connecting piece 400 opposite to the suction nozzle. The connecting pieces 400 are staggered and stacked in the storage frame 300. The storage frame 300 includes a base 310 and a limiting frame 320. The limiting frame 320 is connected to the base 310, and the limiting frame 320 and the base 310 together form a cavity. The limiting frame 320 has an opening on the side facing the identification component 200, and the connecting pieces 400 are placed in the cavity. Please refer to [link to relevant documentation]. Figure 9 and Figure 10The storage box 300 is also equipped with a height recognition component and a lifting component. The height recognition component and the lifting component are electrically connected. The height recognition component is located on the side of the limiting frame 320 away from the base, and the lifting component is located on the base 310. When the height recognition component is triggered, it will continuously send a lifting signal to the lifting component. After receiving the lifting signal, the lifting component will push the connecting piece 400 upward until the height recognition component stops sending the lifting signal. It is conceivable that the height recognition component includes an infrared transmitter 330 and an infrared receiver 340 located near the opening of the limiting frame 320. The infrared transmitter 330 emits infrared signals, and the infrared receiver 340 receives infrared signals. The infrared receiver 340 is positioned opposite the infrared transmitter 330. When the infrared receiver 340 receives an infrared signal, it indicates that the connecting piece 400 has not reached the specified height. The infrared receiver 340 then continuously sends a lifting signal to the lifting component until the lifting component pushes the connecting piece 400 to the specified height, thus blocking the infrared signal emitted by the infrared transmitter 330. When the infrared receiver 340 can no longer receive infrared signals, it stops sending lifting signals, and the lifting component stops lifting upwards. It is understandable that the height recognition component is equivalent to a switch in the lifting component circuit. When the connecting piece 400 does not block the height recognition component, the lifting component circuit is turned on and the lifting component starts. When the connecting piece 400 blocks the height recognition component, the lifting component circuit is turned off and the motor in the lifting component stops moving.

[0096] Please see Figure 11 This application provides a method for identifying the orientation and orientation of a connecting piece 400, applied to a mechanism for identifying the orientation of the connecting piece 400. The mechanism includes a movable component 100 and an identification component 200 connected to each other. The identification component 200 includes: a connecting platform 250 connected to the movable component 100; a first identification component 220 connected to the connecting platform 250; a second identification component 230 connected to the connecting platform 250 and spaced apart from the first identification component 220; and a third identification component 240 connected to the connecting platform 250 and located between the first identification component 220 and the second identification component 230.

[0097] The first identification component 220 includes a first suction nozzle 221, a second suction nozzle 222 and a third suction nozzle 223, which are spaced apart on the connecting platform 250.

[0098] The second identification component 230 includes a fourth suction nozzle 231, a fifth suction nozzle 232, and a sixth suction nozzle 233, which are spaced apart on the connecting platform 250.

[0099] The third identification component 240 includes a pressure sensor 241 connected to the connecting platform 250.

[0100] The method includes the following steps:

[0101] Step S1: Obtain the first vacuum value of the first suction nozzle 221, the second suction nozzle 222 and the third suction nozzle 223 when suctioning the connecting piece 400.

[0102] The first identification component 220 also includes a first vacuum tube 224, which is located on the side of the connecting platform 250 away from the first suction nozzle 221. The first vacuum tube 224 is connected to the first suction nozzle 221, the second suction nozzle 222 and the third suction nozzle 223. The first vacuum tube 224 is connected to a vacuum pump.

[0103] The moving component 100 includes a moving cylinder 130 connected to the connecting platform 250.

[0104] The specific steps for obtaining the first vacuum degree value include:

[0105] Step S101: The moving cylinder 130 drives the first suction nozzle 221, the second suction nozzle 222 and the third suction nozzle 223 to move downward until they contact the connecting piece 400.

[0106] Step S102: The vacuum pump extracts air from the first vacuum suction tube 224 to draw in the connecting piece 400, and records the vacuum level in the first vacuum suction tube 224 at this time as the first vacuum level value.

[0107] Step S2: Obtain the second vacuum value of the fourth suction nozzle 231, the fifth suction nozzle 232 and the sixth suction nozzle 233 when suctioning the connecting piece 400.

[0108] The second identification component 230 also includes a second vacuum tube 234, which is located on the side of the connecting platform 250 away from the fourth nozzle 231. The second vacuum tube 234 is connected to the fourth nozzle 231, the fifth nozzle 232 and the sixth nozzle 233, and is connected to a vacuum pump.

[0109] The specific steps for obtaining the second vacuum degree value include:

[0110] Step S201: The moving cylinder 130 drives the fourth suction nozzle 231, the fifth suction nozzle 232 and the sixth suction nozzle 233 to move downward until they contact the connecting piece 400.

[0111] Step S202: The vacuum pump extracts air from the second vacuum suction tube 234 to draw in the connecting piece 400, and records the vacuum level in the second vacuum suction tube 234 at this time as the second vacuum level value.

[0112] Step S3: Obtain the pressure value of pressure sensor 241. Specifically, the pressure value can be read directly from pressure sensor 241.

[0113] Step S4: Determine the orientation of the connecting piece 400 based on the first vacuum degree value and the second vacuum degree value.

[0114] The mechanism has a second direction Y, and the connecting piece 400 has a notch 410 at one end along the second direction Y. The method for determining the orientation of the connecting piece 400 based on a first vacuum level value and a second vacuum level value includes:

[0115] Step S401: Compare the first vacuum degree value and the second vacuum degree value.

[0116] Step S402: If the first vacuum value is greater than the second vacuum value, then the notch 410 of the connecting piece 400 faces the second identification component 230.

[0117] Step S403: If the first vacuum level value is less than the second vacuum level value, the notch 410 of the connecting piece 400 faces the first identification component 220. Alternatively,

[0118] Step S404: Compare the first vacuum degree value and the second vacuum degree value with the vacuum degree threshold respectively.

[0119] Step S405: If the first vacuum value is equal to the vacuum threshold or the second vacuum value is less than the vacuum threshold, then the notch 410 of the connecting piece 400 faces the second identification component 230.

[0120] Step S406: If the first vacuum value is less than the vacuum threshold or the second vacuum value is equal to the vacuum threshold, then the notch 410 of the connecting piece 400 faces the first identification component 220.

[0121] When there are six suction nozzles, specifically the first group consisting of suction nozzles 221, 222, and 223, and the second group consisting of suction nozzles 231, 232, and 233, both located on the connecting platform 250, the vacuum levels collected by the two groups of nozzles can be compared. Since at least one nozzle in each group is directly opposite the notch 410 of the connecting piece 400, meaning that when the nozzle is pressed down, the nozzle corresponding to the notch 410 in the connecting piece 400 cannot contact the connecting piece 400, one nozzle remains in a suction state after the vacuum pump starts, resulting in a decrease in the vacuum level in the vacuum tube. Therefore, by comparing the two sets of vacuum levels, the orientation of the notch 410 can be determined, which in turn determines the orientation of the connecting piece 400.

[0122] If there are only three suction nozzles, i.e., only one set, it is impossible to compare the data collected from the two sets. Therefore, a vacuum threshold needs to be introduced for comparison. Since there are two states when the three suction nozzles are picking up the connector 400, one state is that all three suction nozzles pick up the connector 400 together, and the other state is that at least one of the three suction nozzles misses, the vacuum value obtained when all three suction nozzles pick up the connector 400 together can be used as the vacuum threshold for comparison.

[0123] Step S5: Determine the orientation of the connecting piece 400 based on the pressure value.

[0124] The connecting piece 400 has a protrusion 420 at one end along its thickness direction. The method for determining the orientation of the connecting piece 400 based on the pressure value includes:

[0125] Step S501: Compare the pressure value with the pressure threshold.

[0126] Step S502: If the pressure value is greater than the pressure threshold, the protrusion 420 of the connecting piece 400 faces the pressure sensor 241, that is, the reverse side of the connecting piece 400 faces upward.

[0127] Step S503: If the pressure value is equal to the pressure threshold, then the protrusion 420 of the connecting piece 400 is away from the pressure sensor 241, that is, the front of the connecting piece 400 is facing upward.

[0128] Since the pressure value is obtained by the pressure sensor 241, when the connecting piece 400 is facing upwards, there is no contact or only slight contact between the pressure sensor 241 and the connecting piece 400, so the value obtained by the pressure sensor 241 is almost 0; when the connecting piece 400 is facing downwards, the pressure sensor 241 is in contact with the protrusion 420, so the pressure value measured by the pressure sensor 241 is greater than 0. Therefore, by setting the pressure threshold value to 0, the orientation of the connecting piece 400 can be determined based on the pressure value obtained by the pressure sensor 241.

[0129] Following step S5, the following is also included:

[0130] S6: Adjust the connecting piece 400 according to its orientation and orientation;

[0131] S601: When the orientation of the protrusion 420 and the notch 410 of the connecting piece 400 does not meet the setting, the connecting piece 400 is moved to the adjustment position by the linear module 110.

[0132] S602: When the orientation of the protrusion 420 of the connecting piece 400 does not conform to the setting, but the orientation of the notch 410 conforms to the setting, the connecting piece 400 is moved to the adjustment position by the linear module 110.

[0133] S603: When the orientation of the protrusion 420 of the connecting piece 400 conforms to the setting, but the orientation of the notch 410 does not conform to the setting, the connecting piece 400 is rotated by the rotary cylinder 210 to adjust its position. After the adjustment is completed, the connecting piece 400 is moved to the processing station by the linear module 110.

[0134] S604: When the orientation of the protrusion 420 and the notch 410 of the connecting piece 400 both meet the settings, the connecting piece 400 is moved to the processing station by the linear module 110.

[0135] In this embodiment, the state in which the notch 410 of the connecting piece 400 faces the first identification component 220 and the protrusion 420 of the connecting piece 400 faces away from the pressure sensor 241 is defined as the set state. That is, when the notch 410 of the connecting piece 400 faces the first identification component 220 and the connecting piece 400 is in the front state, it is determined that the connecting piece 400 meets the set.

[0136] Furthermore, when determining the orientation and orientation of the connecting piece 400, the identification mechanism can quickly determine the orientation and orientation of the connecting piece 400 after pressing down and contacting it, without any sequential judgment. However, since the connecting piece 400 does not meet the processing requirements of the workstation when the front side is facing up, the orientation of the connecting piece 400 is used as the primary factor for judgment. If the connecting piece 400 is facing up, there is no need to judge the orientation of its notch 410, and it can be directly moved to the adjustment station for manual or other mechanism adjustment. If the connecting piece 400 is facing down, regardless of the orientation of the notch 410, the connecting piece 400 is considered to meet the requirements. The difference is that if the orientation of the notch 410 is incorrect, it can be adjusted to a suitable position by rotating the rotary cylinder 210. After adjustment, it can be moved to the processing station by the linear module 110 and / or the rotary cylinder 210.
