Description

Technical Field

[0001] This invention belongs to the field of battery production equipment technology, specifically, it relates to an electrode suction plate with a buffer function and an electrode picking and placing robot having the same. Background Technology

[0002] As one of the core steps in battery production, the precision and efficiency of lamination directly affect the quality and production efficiency of the battery. For existing battery lamination devices, it is relatively difficult to significantly improve lamination efficiency through mechanical structure improvements. Therefore, reducing the error frequency and the number of downtimes in the cell production process are currently effective means to improve the efficiency of lamination devices.

[0003] To reduce damage to the electrodes during stacking and handling and to decrease the frequency of false triggering of overpressure alarms, buffer components are typically installed on the electrode handling robot. These buffer components absorb the pressure borne by the electrode suction plate during electrode handling. However, for stacking machines that require manual loading and unloading, operators usually need to move the magazine filled with electrodes to the designated automatic electrode handling position. The electrode handling robot then descends to the designated height according to the program to pick up the electrodes. To ensure smooth electrode handling, the height of the top electrode in the magazine is adjusted by a lifting device to match the robot's picking height. To ensure that the electrodes in the magazine are picked up smoothly, the lifting device usually needs to repeatedly control the raising and lowering of the electrodes to keep the top electrode at a height that can be picked up. This adjustment process is usually achieved through photoelectric sensors for sensing and control.

[0004] However, in actual use, it was found that the photoelectric sensor could not maintain a stable sensitivity during repeated triggering. Therefore, the position of the top electrode was not fixed after each adjustment. Correspondingly, the buffer stroke of the buffer assembly was not fixed, and the magnitude of the force applied during each buffering was not the same. When the height of the top electrode of the magazine was higher than the actual electrode picking height, the increased buffer stroke may cause the buffer assembly to collide with the negative pressure interface on the back of the suction plate, resulting in damage to the negative pressure interface. The buffer assembly itself may also deform due to overpressure or collision, thus failing to ensure that the suction plate and the electrode are always parallel to each other. The above problems affected the working continuity of the stacking machine to varying degrees, directly affecting the working efficiency of the stacking machine.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] To address one of the problems in the prior art, this invention provides an electrode suction plate with a buffer function. The suction plate is connected to a buffer assembly including a guide post, a connector that can slide on the guide post, and a reset unit that provides a buffering force to the connector. A protrusion protruding to one side of the suction plate is formed on the connector, and a connecting groove for connecting to a drive member is formed on the other side opposite to the protrusion. This design limits the stroke of the buffer assembly to avoid collision with the negative pressure interface while improving the deformation resistance of the connector.

[0007] The present invention also provides an electrode picking and placing robot using the above-mentioned electrode suction plate, which can better adapt to the production process of stacking machines with manual loading and unloading, and significantly improve the production efficiency of stacking machines.

[0008] To achieve the above objectives, the first aspect of the present invention provides an electrode plate stacking device with a buffer function, comprising a suction plate body and a buffer assembly. One side of the suction plate body is an adsorption surface, and the side away from the adsorption surface has a plurality of protruding negative pressure ports. The buffer assembly includes a guide post, a connector, a limiting member, and a reset unit. The guide post is arranged perpendicular to the adsorption surface and connected to the side of the suction plate body away from the adsorption surface. The connector cooperates with the guide post and is slidably arranged along the length direction of the guide post. The limiting member is connected to the end of the guide post to limit the connector. The reset unit is connected to the connector and is used to continuously provide a force to drive the connector to move closer to the limiting member. A protrusion is formed on the side of the connector near the suction plate body, the protrusion is arranged to avoid the negative pressure ports, and the protrusion length is greater than the height of the negative pressure ports.

[0009] Furthermore, the connector is provided with a through hole that mates with the guide post, and the protrusion is arranged to avoid the through hole along a first direction parallel to the adsorption surface, with both ends in the first direction flush with the edge of the connector.

[0010] Furthermore, a connecting groove is formed on the side of the connector away from the suction plate body. The connecting groove is disposed opposite to the protrusion, extends along the first direction, and forms an opening at the edge of the connector.

[0011] Furthermore, the bottom of the connecting groove is flat, and it remains parallel to the adsorption surface throughout the sliding process of the connector along the guide post.

[0012] Furthermore, the connector has a hollowed-out section in the middle, with the hollowed-out area located inside the connecting groove.

[0013] Furthermore, the middle part of the connecting groove extends towards the edge of the connector along a second direction perpendicular to the first direction in the horizontal plane to form a wing.

[0014] Furthermore, the connector has a hollowed-out section in the middle, with the hollowed-out area located inside the connecting groove.

[0015] Furthermore, the connector includes two first connecting arms and two second connecting arms that are perpendicular to each other. The first connecting segment is arranged along the second direction and includes two connecting segments, a groove arm segment that is connected to one end of each of the two connecting segments and forms an angle between the connecting segments, and a groove bottom segment that is connected to the two groove wall segments at both ends. The groove bottom segment and the two groove wall segments together serve as the protrusion of the connector and form a partial connecting groove on the side away from the suction plate body to connect the hollow area with the outside of the connector. The second connecting arms are arranged along the first direction and are connected to the ends of the two first connecting arms at both ends.

[0016] Furthermore, the connector has at least an axis of symmetry parallel to the first direction, and the connecting groove is symmetrically arranged about the axis of symmetry.

[0017] A second aspect of the present invention provides an electrode picking and placing robot, including a drive assembly and an electrode suction plate as described above, wherein the drive assembly is connected to a connector.

[0018] Furthermore, the drive assembly includes a drive arm and a connecting block connected to the end of the drive arm. The length of the connecting block in a first direction is greater than the length of the connector, and the width of the connecting block in a second direction is adapted to the width of the connecting groove. When the drive assembly is connected to the connector, the connecting block is embedded in the connecting groove.

[0019] Furthermore, when the drive component is connected to the connector, the connecting block fits into the bottom of the connecting groove.

[0020] Furthermore, the drive assembly also includes a sensor assembly, which protrudes from the side of the connecting block facing the suction plate body. The suction plate body has a sensing hole corresponding to the position of the sensor assembly, and a clearance groove for avoiding the sensor assembly.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0022] 1. A protrusion is formed on the side of the connector near the suction plate body. The length of the protruding part is greater than the height of the negative pressure port. This provides a buffer stroke for the suction plate body and avoids collision between the connector and the negative pressure port.

[0023] 2. The electrode suction plate is connected to the drive assembly through a connecting groove located on the side of the connector away from the suction plate body, which improves the convenience of connection. The connecting groove and the protrusion are set opposite to each other, making the structure more stable and preventing deformation after collision. When the connecting block of the drive assembly is embedded in the connecting groove, it has higher connection stability and connection accuracy, which can prevent the parallelism of the electrode suction plate from decreasing due to deformation of the connecting groove.

[0024] 3. The sensor is connected to the end of the connecting block of the drive component. The middle of the connecting groove is hollowed out to avoid collision between the connecting part and the sensor. Attached Figure Description

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] This invention provides an electrode suction plate with a buffer function, such as... Figures 1 to 4 As shown, the device includes a suction plate body 1 and a buffer assembly. One side of the suction plate body 1 is an adsorption surface, with a pre-set negative pressure passage inside. One end of the negative pressure passage forms an opening on the adsorption surface, and the other end forms a negative pressure port 11 on the surface of the suction plate body 1 facing away from the adsorption surface. The negative pressure port 11 protrudes from the suction plate body 1 to facilitate connection to a negative pressure generating device. The buffer assembly includes a guide post 3, a connector 2, a limiting member 4, and a reset unit (not shown). The guide post 3 is connected to the suction plate body 1 and protrudes from the side facing away from the adsorption surface in a direction perpendicular to the adsorption surface. The connector 2 is slidably connected to the guide post 3 along its length. The limiting member 4 is located on the guide post 3. At the end of column 3, to prevent connector 2 from detaching from guide column 3, reset unit (not shown) is connected to connector 2 to continuously provide force for connector 2 to move along guide column 3 toward the side closer to limit member 4; to prevent connector 2 from colliding with negative pressure port 11, connector 2 has a protruding protrusion 21 on the side facing suction plate body 1. The protrusion 21 is offset from negative pressure port 11, and the protrusion height of protrusion 21 is greater than the height of negative pressure port 11, thereby preventing connector 2 from colliding with negative pressure port 11 when moving. In addition, the presence of protrusion 21 improves the structural stability of connector 2 and prevents deformation due to collision.

[0036] The structure of the electrode picking and placing robot with the above-mentioned electrode suction plate is as follows: Figure 5 and Figure 6 As shown, it also includes a drive assembly connected to the electrode suction plate and driving the electrode suction plate to move. The drive assembly is connected to the connector 2. The presence of the protrusion 21 improves the stability of the connector 2. During repeated disassembly and assembly and use, the connector 2 will not deform due to fatigue or impact, thereby ensuring a stable connection between the drive assembly and the connector 2. This facilitates precise control of the electrode suction plate installation angle and prevents the electrode suction plate from shaking or shifting under the influence of force due to deformation of the connector 2, ensuring smooth electrode placement and removal.

[0037] For ease of explanation, in one embodiment of the present invention, the reset unit (not shown) is configured as a spring sleeved on the guide post 3. One end of the spring abuts against the connector 2, and the other end abuts against the side surface of the suction plate body 1 away from the adsorption surface. The spring is always in a compressed state, thereby continuously providing the connector 2 with a force to move towards the limiting member 4. In other embodiments, the reset unit (not shown) may also be made of other materials with a certain elastic deformation capability. For example, the reset unit (not shown) may be configured as a rubber sleeve, sleeved on the guide post 3 between the connector 2 and the suction plate body 1, and using elastic restoring force to provide force to the connector 2 when compressed.

[0038] Furthermore, the limiting member 4 and the guide post 3 can be connected using conventional methods in the art, such as screwing, snap-fitting, or plugging. Specifically, when the limiting member 4 and the guide post 3 are screwed together, the end of the guide post 3 is provided with a threaded hole. The limiting member 4 includes a blocking part for preventing the connector 2 from disengaging, and a threaded part that mates with the threaded hole. The threaded part and the blocking part can be integrally formed, or they can be detachably set from each other, or they can be designed as two independent parts that abut against each other when installed in place. When the two are designed as two independent parts, specifically, the blocking part can be a washer that at least partially covers the through hole on the connector 2, and the threaded part can be a screw with threads, the size of which is larger than the hollow area in the middle of the washer.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0040] Example 1

[0041] As an embodiment of the present invention, this embodiment provides an electrode suction plate with a buffer function, the specific structure of which is as follows.

[0042] In this embodiment, as Figure 1 As shown, the suction plate body 1 is generally a flat plate, with an adsorption surface on one side and a plane parallel to the adsorption surface on the other side. The negative pressure port 11 protrudes from the side of the suction plate body 1 away from the adsorption surface. The suction plate body 1 has two axes of symmetry that are parallel to the adsorption surface and perpendicular to each other. Four guide posts 3 are connected to the side of the suction plate body 1 away from the adsorption surface. The four guide posts 3 are parallel to each other and arranged in a rectangular array. Any two adjacent guide posts 3 are symmetrically arranged about one of the axes of symmetry of the suction plate body 1. The connector 2 has through holes corresponding to the positions of the four guide posts 3. The four guide posts 3 pass through the four through holes to limit the movement path of the connector 2. The four guide posts 3 have the same length. In order to provide sufficient buffer displacement for the connector 2, the length of the guide posts 3 is greater than the height of the negative pressure port 11 protruding from the side of the suction plate body 1 away from the adsorption surface.

[0043] Further, the projection of the connecting member 2 on a plane parallel to the adsorption surface is rectangular, the projections of the four through holes are respectively located at four corners of the rectangle, and the projection areas of the four through holes and the projection of the connecting member 2 share a common symmetry axis, which ensures uniform force bearing of the buffer assembly and improves the stability of the pole piece suction plate; a convex portion 21 is provided protruding on a side of the connecting member 2 facing the suction plate body 1, in this embodiment, the projection of the convex portion 21 on the plane parallel to the adsorption surface is rectangular, and an end of the convex portion 21 close to the suction plate body 1 is a flat surface, the flat surface is parallel to the side surface of the suction plate body 1 facing away from the adsorption surface, thereby ensuring that no slipping or misalignment occurs when the convex portion 21 is in contact with the suction plate body 1; in order to avoid collision between the connecting member 2 and the negative pressure port 11, the convex portion 21 is arranged to avoid the negative pressure port 11, taking the plane where the end surface of the convex portion 21 of the suction plate is located as a first plane, and the plane where the area other than the convex portion 21 is located as a second plane, the distance between the first plane and the suction plate body 1 is smaller than the distance between the second plane and the end of the negative pressure port 11, so that the displacement of the connecting member 2 can be limited by the convex portion 21 before the connecting member 2 collides with the negative pressure port 11.

[0044] The directions in which the two symmetry axes of the suction plate body 1 extend are defined as a first direction and a second direction respectively. In order to further improve the structural stability of the connecting member 2, the convex portion 21 in this embodiment extends along the first direction, and both ends of the convex portion 21 are flush with the two side edges of the connecting member 2 in the first direction, that is, the cross-sectional shape of the connecting member 2 in the first direction is the same, and all are in a "convex" shape; at this time, the convex portion 21 also serves as a reinforcing rib for improving the structural stability of the connecting member 2, ensuring that the connecting member 2 will not deform due to fatigue or impact under long-term force bearing.

[0045] Embodiment II

[0046] As another embodiment of the present invention, this embodiment further makes the following improvements based on Embodiment I.

[0047] In this embodiment, as Figure 2 shown in the drawings, the connecting member 2 is further provided with a connecting groove 22, the connecting groove 22 is located on a side of the connecting member 2 facing away from the suction plate body 1, and is formed by recessing towards the direction close to the suction plate body 1, for realizing stable connection between the connecting member 2 and a driving assembly that drives the pole piece suction plate to move.

[0048] Specifically, the connecting groove 22 in this embodiment is disposed opposite to the convex portion 21, that is, the projection of the connecting groove 22 on the plane parallel to the adsorption surface is located inside the projection of the convex portion 21 on this plane, the groove bottom of the connecting member 2 is a flat surface parallel to the adsorption surface, thereby when connected to the driving assembly, sufficient contact with the connecting member 2 can be ensured, the occurrence of misalignment and sliding is reduced or even avoided, and connection convenience and connection stability are improved.

[0049] Furthermore, the connecting groove 22 extends along the first direction and forms openings at the two side edges of the connector 2 in the first direction, which improves the compatibility of the connecting groove 22 with drive components of different sizes and reduces the connection difficulty. It further increases the area that can contact the drive components and improves the connection stability. Due to the presence of the connecting groove 22, the protrusion 21 region includes two first sidewalls perpendicular to the connector 2 and a second sidewall parallel to the connector 2. The inner side of the first sidewall forms the groove wall of the connecting groove 22. The inner side of the second sidewall serves as the bottom wall of the connecting groove 22. The two first sidewalls have the same thickness, making the connector 2 symmetrical as a whole. Due to the presence of the first sidewall, the part other than the protrusion 21 and the end face of the protrusion 21 are connected through the first sidewall, forming two "Z"-shaped structures located on both sides of the axis of symmetry of the connector 2, which can better resist the deformation of the connector 2.

[0050] To further improve the connection stability between the connector 2 and the drive assembly, the middle part of the connecting groove 22 extends along the second direction to form a wing, that is, the connecting groove 22 is in the shape of a cross.

[0051] Example 3

[0052] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment two as follows.

[0053] In this embodiment, as Figure 3 and Figure 4 As shown, the suction plate body 1 has a hollowed-out section in the middle to avoid the sensor. At this time, the connector 2 can be divided into two first connecting arms 201 and two second connecting arms 202 that form the hollowed-out area. The first connecting arms 201 are arranged along the second direction and are parallel to each other. They include two connecting segments 2011 at the ends, two groove wall segments 2012 that are perpendicular to the connecting segments 2011, and a groove bottom segment 2013 that is connected to the ends of the two groove wall segments 2012. The groove wall segments 2012 are the first sidewalls and the groove bottom segment 2013 are the second sidewalls. The second connecting arms 202 are arranged perpendicular to the connecting segments 2011 and the groove wall segments 2012 and connect the two first connecting arms 201 from both ends of the first connecting arms 201 respectively. The hollowed-out area forms a space for installing the sensor, and a sensing port that is opposite to the position of the sensor and is arranged through the sensor is formed on the suction plate body 1.

[0054] Example 4

[0055] As another embodiment of the present invention, the difference between this embodiment and embodiment three is that the number and placement of the buffer components are different;

[0056] Specifically, in this embodiment, two sets of buffer components are provided on the side surface of the suction plate body 1 away from the adsorption surface. The two sets of buffer components are symmetrical to each other and are respectively arranged close to the opposite sides of the suction plate body 1. The structure of each set of buffer components is the same as that in Embodiment 3. The suction plate body 1 has a sensing port opposite to the position of the buffer components.

[0057] The present invention also provides an electrode picking and placing robot having the electrode suction plate described in the above embodiments, as detailed below.

[0058] Example 5

[0059] As another embodiment of the present invention, this embodiment provides a robotic arm for picking up and placing electrode sheets, such as... Figure 5 and Figure 6 As shown, the device includes a drive assembly and the suction plate body 1 described in Embodiment 3. The drive assembly includes a drive arm 5, and a connecting block 6 is provided at the end of the drive arm 5. The connecting block 6 is connected to the connecting member 2 on the electrode suction plate, and the other end of the drive arm 5 is connected to the drive unit 7.

[0060] Specifically, the length of the connecting block 6 in the first direction is greater than the length of the connecting member 2, and the width in the second direction is adapted to the width of the connecting groove 22. Thus, during connection, the connecting block 6 can be embedded in the connecting groove 22, and the connecting groove 22 limits the connection of the connecting block 6 to achieve a stable connection between the electrode suction plate and the drive assembly. Furthermore, the electrode suction plate can be adjusted in the first direction to match the connecting block 6, which facilitates adjustment.

[0061] To improve connection stability, the side of the connecting block 6 facing the bottom of the connecting groove 22 is flat. When the two are connected in place, the connecting block 6 and the bottom of the connecting groove 22 fit together, further improving connection stability.

[0062] Furthermore, the drive assembly also includes a sensor assembly 8, which protrudes from the side surface of the connecting block 6 facing the connecting groove 22. When the connecting block 6 is embedded in the connecting groove 22, the sensor assembly 8 is embedded in the hollow area of ​​the connector 2. The distance between the sensor assembly 8 and the side surface of the suction plate body 1 away from the adsorption surface is greater than the distance between the first plane and the side surface of the suction plate body 1 away from the adsorption surface.

[0063] To improve the accuracy of the sensor, a clearance groove (not shown) corresponding to the sensor assembly 8 is provided on the side of the suction plate body 1 away from the adsorption surface. The distance between the sensor assembly 8 and the bottom of the clearance groove (not shown) is greater than the distance between the first plane and the surface of the suction plate body 1 away from the adsorption surface.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
