Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a pressure-reducing device and a welding apparatus using the pressure-reducing device. Background Technology

[0002] In related technologies, when welding the sealing pins inside the injection holes of a battery device, the battery device containing the sealing pins is usually transported to a pressing device to press down the sealing pins, thereby facilitating subsequent stable welding.

[0003] However, errors are inevitable during the process of conveying the battery device with the sealing pin to the pressing device, such as conveying errors or manufacturing errors in the clamps holding the battery device. These errors can cause misalignment between the sealing pin and the pressing device after the battery is in place, leading to problems such as the sealing pin lifting or shifting when pressed. Utility Model Content

[0004] The main objective of this application is to provide a pressing device and welding equipment, which aims to enable the pressing element to accurately correspond with the element to be pressed, so as to apply stable pressure to the element to be pressed.

[0005] To achieve the above objectives, the pressing device proposed in this application includes:

[0006] First drive mechanism;

[0007] The pressing member is connected to the first drive mechanism; and

[0008] A position detection mechanism is configured to identify the position information of the part to be clamped.

[0009] The first drive mechanism is electrically connected to the position detection mechanism and is configured to drive the pressing member to move to the position corresponding to the member to be pressed and press against the member based on the position information identified by the position detection mechanism.

[0010] The pressing member has a pressing surface on one side in the first direction, and the pressing surface is configured to press against the member to be pressed; the first driving mechanism is configured to drive the pressing member to move at least along the second direction and the third direction, so that the pressing member corresponds to the member to be pressed, and the first direction, the second direction and the third direction intersect each other; the first driving mechanism includes a first driving assembly and a second driving assembly; the second driving assembly is connected to the first driving assembly, and the pressing member is connected to the second driving assembly; the first driving assembly is configured to drive the second driving assembly and the pressing member to move along the second direction, and the second driving assembly is configured to drive the pressing member to move along the third direction.

[0011] The pressing device in this application detects the position of the component to be pressed by means of a position detection mechanism. Furthermore, the position detection mechanism is electrically connected to a first drive mechanism, allowing the first drive mechanism to drive the pressing component to accurately align with the component based on the position information detected by the position detection mechanism. This achieves stable pressing of the component and reduces the possibility of the pressing component tilting or shifting during pressing due to misalignment. Furthermore, configuring the first drive mechanism to drive the pressing component to move at least along a second and a third direction diversifies the driving path of the pressing component, ensuring accurate alignment with the component in both directions. Including a first drive assembly and a second drive assembly reduces the number of components in the first drive mechanism and facilitates programming control, thus improving the ease of manufacturing the pressing device.

[0012] In some embodiments, the first drive mechanism further includes a third drive component connected to the first drive component, a second drive component connected to the third drive component, and the third drive component configured to drive the second drive component and the pressing member to move along a first direction;

[0013] Alternatively, the third drive assembly is connected to the second drive assembly, and the pressing member is connected to the third drive assembly, wherein the third drive assembly is configured to drive the pressing member to move along the first direction.

[0014] This allows the pressing member to have a height difference with the part to be pressed in the first direction. Then, the third driving component drives the pressing member to approach and press against the part to be pressed in the first direction, so that the pressing member will not interfere with the part to be pressed when it is transported.

[0015] In some embodiments, the pressing device further includes a mounting plate, and the first driving assembly is disposed on one side of the mounting plate in a first direction;

[0016] The position detection mechanism is located on the other side of the mounting plate in the first direction. The mounting plate has an exposure hole that extends through both sides of the mounting plate in the first direction and is configured to expose the part to be pressed.

[0017] This allows for full utilization of the space on the top and bottom sides of the mounting plate, reducing the overall size of the pressing device. Simultaneously, the mounting plate can also press against the load-bearing component of the part to be pressed, facilitating more stable welding work later.

[0018] In some embodiments, the mounting plate includes:

[0019] A first plate, a first driving component disposed on the first plate; and

[0020] The second plate is connected to the first plate and has an exposure hole. At least a portion of the second plate protrudes from the first plate and is disposed on the side facing the first drive assembly.

[0021] The second plate is also provided with a clearance groove on the side facing the first drive assembly. The clearance groove extends along a third direction, and one end of the third direction is connected to the exposure hole, while the other end penetrates the second plate. The clearance groove is configured to allow the pressing member to extend into it.

[0022] Therefore, when the carrier of the component to be pressed is pressed by the protruding second plate, the pressing component can be located above the carrier, which facilitates the subsequent insertion of the slot into the exposed hole and the descent under the drive of the third drive assembly to press against the component to be pressed below the exposed hole.

[0023] In some embodiments, the second plate is detachably connected to the first plate.

[0024] Therefore, when installing load-bearing components of different sizes, the second plate of the corresponding size can be replaced accordingly, improving the versatility of the pressing device.

[0025] In some embodiments, the pressing device further includes a second driving mechanism connected to the mounting plate and configured to drive the mounting plate to move at least along a first direction.

[0026] Therefore, the mounting plate can be driven to descend to press against the carrier on which the component to be pressed is mounted. Thus, before the carrier is transported, the mounting plate can form a height difference with the carrier, so that it will not interfere with the transport of the carrier.

[0027] In some embodiments, the pressing device further includes a third driving mechanism, which is connected to the position detection mechanism and configured to drive the position detection mechanism to move;

[0028] And / or, the position detection mechanism includes a CCD camera.

[0029] Therefore, the third drive mechanism can drive the position detection mechanism to move, allowing it and the second drive mechanism to move and avoid each other when they are on the same side of the mounting plate, minimizing the risk of interference. By including a CCD camera in the position detection mechanism, high-precision visual positioning and detection technology can be used to identify and detect the part to be pressed, thereby improving the accuracy of identifying and detecting the position information of the part.

[0030] On the other hand, the welding equipment proposed in this application includes:

[0031] Welding equipment; and

[0032] In any of the above embodiments, the pressing device is configured to weld the part to be pressed to the carrier on which the part to be pressed is mounted. Attached Figure Description

[0044] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0048] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0049] During the manufacturing process of battery devices, after the battery device is filled with electrolyte, a sealing pin is usually welded and installed inside the filling hole. Furthermore, to improve efficiency, the sealing pin is pre-placed inside the filling hole of the battery device. The battery device is then clamped by a fixture and transported by a conveyor to the welding equipment for welding. At this point, to facilitate stable welding of the sealing pin, a pressure device is used to press down on the conveyed sealing pin during welding.

[0050] In related technologies, the pressing device for pressing the sealing pin typically uses a pneumatic drive, such as a cylinder, to extend the pressing component in a single horizontal direction. However, the fixed extension distance of the pneumatic drive results in a fixed extension position for the pressing component. Nevertheless, errors can occur during the transport of the battery device by the conveying mechanism, and manufacturing errors can also exist in the clamping angle of the battery device. These errors can cause a misalignment between the sealing pin on the battery device and the preset conveying position of the corresponding pressing component when the battery device is transported to the welding equipment. This misalignment can lead to problems such as the sealing pin lifting or shifting when pressed.

[0051] Therefore, based on the above considerations, in order to solve the problem that the sealing pins on the battery pressing device are prone to misalignment and deviation, causing the sealing pins to lift or shift, this application proposes a novel pressing device. This pressing device innovatively incorporates a position detection mechanism to identify and detect the position information of the sealing pins awaiting pressing. Simultaneously, an electrical connection is established between the first driving mechanism and the position detection mechanism, enabling the first driving mechanism to drive the pressing component to move accurately to correspond with the pressing component based on the identified position information configured by the detection mechanism, thus achieving stable pressing of the component to be pressed.

[0052] Furthermore, it should be noted that the pressing device proposed in this application can be, as described above, applied to welding equipment to press against the workpiece to be pressed during welding. Of course, the pressing device can also be applied to cutting equipment to press against the workpiece to be pressed during cutting; this application does not limit the type of equipment to which the pressing device is applied. Moreover, the workpiece to be pressed by the pressing device can be, as described above, a sealing pin installed in the electrolyte filling hole of a battery device, or other workpieces that require pressing during processing; this application also does not limit the type of workpiece to be pressed.

[0053] The structure of the pressing device proposed in this application will be explained and illustrated below with examples:

[0054] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the pressing device 10 includes a first driving mechanism 11, a pressing member 13, and a position detection mechanism 15; the pressing member 13 is connected to the first driving mechanism 11; the position detection mechanism 15 is configured to identify the position information of the member to be pressed; wherein, the first driving mechanism 11 is electrically connected to the position detection mechanism 15 and is configured to drive the pressing member 13 to move to a position corresponding to the member to be pressed and press the member to be pressed based on the position information identified by the position detection mechanism 15.

[0055] The first drive mechanism 11 can be used to drive the pressing member 13 to move. When the pressing member 13 presses against the member to be pressed along a first direction, the first drive mechanism 11 can drive movement along at least one of a second direction and a third direction, where the first, second, and third directions intersect each other. Furthermore, when the pressing device 10 is in normal installation and use, with the ground as a reference, the first direction can be vertical, and the second and third directions can be two horizontal directions. Of course, in other embodiments, the first, second, and third directions can be other directions; this application does not limit the specific orientation of the first, second, and third directions. In addition, the first drive mechanism 11 can be a structure including a first drive assembly 111 and a second drive assembly 113 as described below, or it can be a robotic arm structure; this application does not limit the structural type of the first drive mechanism 11.

[0056] The pressing member 13 can be used to press down on the sealing nail or other components to be pressed. The pressing member 13 can be a cylindrical structure or a plate structure; this application does not limit the structural type or shape of the pressing member 13. Furthermore, the pressing member 13 and the first driving mechanism 11 can be detachably connected, for example, by screws, snap-fit ​​connections, or magnetic connections, so that the pressing member 13 can be replaced. Alternatively, the pressing member 13 and the first driving mechanism 11 can be non-detachably connected, for example, by adhesive bonding or welding; this application does not limit the connection method between the pressing member 13 and the first driving mechanism 11. In addition, the number of pressing members 13 can be one, or at least two, to press down on two components to be pressed down respectively.

[0057] The position detection mechanism 15 can be used to identify and detect the position information of the part to be pressed, and is electrically connected to the first drive mechanism 11 so that the first drive mechanism 11 can drive the pressing member 13 to move accurately to correspond with the part to be pressed based on the position information identified by the position detection mechanism 15. The position detection mechanism 15 can identify the center of the part to be pressed, using it as the position information of the part. For example, the position detection mechanism 15 can be a CCD camera as described below, used to visually scan the outline of the part to be pressed and identify the center of the outline, using the center of the outline as the position information of the part to be pressed. Alternatively, the position detection mechanism 15 can include a lidar, used to laser scan the outline of the part to be pressed and identify the center of the outline, using the center of the outline as the position information of the part to be pressed. Therefore, this application does not limit the structural type of the position detection mechanism 15. Furthermore, the electrical connection between the first drive mechanism 11 and the position detection mechanism 15 can be a direct electrical connection between the first drive mechanism 11 and the position detection mechanism 15. For example, the first drive mechanism 11 directly integrates a controller to control the first drive mechanism 11 to drive the pressing member 13 to accurately move to the position corresponding to the part to be pressed after receiving the position information of the part to be pressed from the position detection mechanism 15. In this case, the electrical connection between the first drive mechanism 11 and the position detection mechanism 15 can be made through an electrical connection structure 20 such as a wire harness or a flexible circuit board. Alternatively, the first drive mechanism 11 and the position detection mechanism 15 can also be indirectly electrically connected. For example, the pressing device 10 can also include a controller, which is electrically connected to both the position detection mechanism 15 and the first drive mechanism 11, thus achieving an indirect electrical connection between them. In this case, after the position detection mechanism 15 identifies and detects the position information of the part to be pressed, it can transmit it to the controller, which can then control the first drive mechanism 11 to drive the pressing member 13 to accurately move to the position corresponding to the part to be pressed. Furthermore, the electrical connection between the controller and the first drive mechanism 11 and the position detection mechanism 15 can also be made through an electrical connection structure 20 such as a wire harness or a flexible circuit board. Furthermore, when the first drive mechanism 11 includes a first drive component 111 and a second drive component 113 as described below, both the first drive component 111 and the second drive component 113 may be electrically connected to the position detection mechanism 15.

[0058] The pressing device 10 in this application, by setting a position detection mechanism 15, can detect the position information of the part to be pressed. Furthermore, the position detection mechanism 15 is electrically connected to the first driving mechanism 11, so that the first driving mechanism 11 can drive the pressing member 13 to move to accurately correspond with the part to be pressed based on the position information of the part to be pressed identified by the position detection mechanism 15. This achieves stable pressing of the part to be pressed, thereby reducing the possibility of the pressing member 13 lifting or shifting when pressed due to misalignment between the pressing member 13 and the part to be pressed.

[0059] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the pressing member 13 is provided with a pressing surface 131 on one side in the first direction, and the pressing surface 131 is configured to press against the member to be pressed; the first driving mechanism 11 is configured to drive the pressing member 13 to move at least along the second direction and the third direction, so that the pressing member 13 corresponds to the member to be pressed.

[0060] When the first direction is vertical as described above, the pressing surface 131 can be the lower surface of the pressing member 13. Furthermore, the pressing surface 131 can be a plane, or it can be an arc surface; this application does not limit the shape of the pressing surface 131. The first driving mechanism 11 is configured to drive the pressing member 13 to move at least along the second and third directions. That is, the first driving mechanism 11 can be used only to drive the pressing member 13 to move along the second and third directions; of course, it can also be used to further drive the pressing member 13 to move along the first direction in addition to driving it to move along the second and third directions.

[0061] In this embodiment, the first driving mechanism 11 is configured to drive the pressing member 13 to move along the second direction and the third direction, which makes the driving path of the first driving mechanism 11 for the pressing member 13 more diversified, so that the pressing member 13 can be driven to move in both the second direction and the third direction to accurately correspond with the member to be pressed.

[0062] Please refer to the reference. Figures 1 to 4 In one embodiment of this application, the first driving mechanism 11 includes a first driving component 111 and a second driving component 113; the second driving component 113 is connected to the first driving component 111, and the pressing member 13 is connected to the second driving component 113; the first driving component 111 is configured to drive the second driving component 113 and the pressing member 13 to move along a second direction, and the second driving component 113 is configured to drive the pressing member 13 to move along a third direction.

[0063] The first drive assembly 111 can be used to drive the second drive assembly 113 to move along a second direction. The first drive assembly 111 can be, as described below, a first motor 1111, a first lead screw 1112, a first nut seat 1113, and a first telescopic rod 1114. Alternatively, the first drive assembly 111 can also include the first motor 1111, the first lead screw 1112, and the first nut seat 1113, with the second drive assembly 113 connected to the first nut seat 1113. Or, the first drive assembly 111 can also include the first motor 1111, a first driving wheel, a first driven wheel, and a first belt sleeved on the first driving wheel and the first driven wheel, with the second drive assembly 113 connected to the first belt. Therefore, this application does not limit the structural type of the first drive assembly 111, and it is not limited to lead screw drive, belt drive, or chain drive, etc. The second drive assembly 113 can be used to drive the pressing member 13 to move along a third direction. The second drive assembly 113 may include, as described below, a second motor 1131, a second lead screw 1132, a second nut seat 1133, and a second telescopic rod 1134. Alternatively, the second drive assembly 113 may also include a second motor 1131, a second lead screw 1132, and a second nut seat 1133, with the pressing member 13 connected to the first nut seat 1113. Or, the second drive assembly 113 may include a second motor 1131, a second driving wheel, a second driven wheel, and a second belt fitted onto the second driving wheel and the second driven wheel, with the pressing member 13 connected to the second belt. Therefore, this application does not limit the structural type of the second drive assembly 113, and it is not limited to lead screw drive, belt drive, or chain drive. Furthermore, the first drive assembly 111 and the second drive assembly 113 may use the same transmission method, or they may use different transmission methods.

[0064] In this embodiment, the first drive mechanism 11 includes a first drive component 111 and a second drive component 113, which can reduce the number of parts in the first drive mechanism 11 and facilitate programming control, thereby improving the ease of manufacturing the pressing device 10.

[0065] Please refer to the reference. Figure 3 and Figure 6In one embodiment of this application, the first drive assembly 111 includes a first motor 1111, a first lead screw 1112, a first nut seat 1113, and a first telescopic rod 1114; the first lead screw 1112 extends along a second direction, is connected to the first motor 1111, and can be driven to rotate by the first motor 1111; the first nut seat 1113 is sleeved on the first lead screw 1112 and can be driven to move along the second direction by the rotating first lead screw 1112; the first telescopic rod 1114 is connected to the first nut seat 1113 and can be sleeved on the first lead screw 1112; and the second drive assembly 113 is connected to the first telescopic rod 1114.

[0066] In this embodiment, the first drive assembly 111 is configured to include a first motor 1111, a first lead screw 1112, a first nut seat 1113, and a first telescopic rod 1114. The first telescopic rod 1114 extends and retracts along the axial direction of the first lead screw 1112, thereby driving the second drive assembly 113 to move in the second direction. In this configuration, the lead screw drive offers high precision and stability, thereby improving the accuracy and stability of the first drive assembly 111's drive of the second drive assembly 113. Furthermore, the components can be arranged compactly, reducing the overall size of the first drive assembly 111 and improving the ease of installation.

[0067] In one embodiment of this application, the first motor 1111 may be one end of the first lead screw 1112 located axially.

[0068] Of course, to further improve the compactness between structures, please refer to the reference. Figure 3 and Figure 6 In one embodiment of this application, the first motor 1111 may also be arranged side by side with the first lead screw 1112. In this case, the first drive assembly 111 may further include a first synchronous belt 1115 to transmit the drive of the first motor 1111 to the first lead screw 1112. Alternatively, the first drive assembly 111 may further include a gear set to transmit the drive of the first motor 1111 to the first lead screw 1112.

[0069] Please refer to the reference. Figure 3 and Figure 7In one embodiment of this application, the second drive assembly 113 includes a second motor 1131, a second lead screw 1132, a second nut seat 1133, and a second telescopic rod 1134; the second lead screw 1132 extends in a third direction and is connected to the second motor 1131 and can be driven to rotate by the second motor 1131; the second nut seat 1133 is sleeved on the second lead screw 1132 and can be driven to move in a third direction by the rotating second lead screw 1132; the second telescopic rod 1134 is connected to the second nut seat 1133 and can be sleeved on the second lead screw 1132, and the pressing member 13 is connected to the second telescopic rod 1134.

[0070] In this embodiment, the second drive assembly 113 is configured to include a second motor 1131, a second lead screw 1132, a second nut seat 1133, and a second telescopic rod 1134, such that the second telescopic rod 1134 can extend and retract along the axial direction of the second lead screw 1132, thereby driving the pressing member 13 to move in a third direction. In this case, the lead screw drive has high precision and stability, which helps to improve the accuracy and stability of the second drive assembly 113 in driving the pressing member 13. At the same time, the various components can be arranged compactly, which helps to reduce the overall size of the second drive assembly 113 and improve the convenience of its installation. In one embodiment of this application, the second motor 1131 may be located at one end of the second lead screw 1132 along its axial direction.

[0071] Of course, to further improve the compactness between structures, please refer to the reference. Figure 3 and Figure 7 In one embodiment of this application, the second motor 1131 may also be arranged side by side with the second lead screw 1132. In this case, the second drive assembly 113 may further include a second synchronous belt 1135 to transmit the drive of the second motor 1131 to the second lead screw 1132. Alternatively, the second drive assembly 113 may further include a gear set to transmit the drive of the second motor 1131 to the second lead screw 1132.

[0072] Please refer to the reference. Figures 1 to 5 In one embodiment of this application, the first driving mechanism 11 further includes a third driving component 115, which is connected to the first driving component 111, and a second driving component 113 is connected to the third driving component 115. The third driving component 115 is configured to drive the second driving component 113 and the pressing member 13 to move along a first direction.

[0073] The third drive assembly 115 can be used to drive the second drive assembly 113 and the pressing member 13 to move along a first direction, so that the pressing member 13 can approach and press against the member to be pressed. To simplify the result of the third drive assembly 115, it can be configured as a cylinder. Of course, in other embodiments, the third drive assembly 115 can also be configured with the same structure as the first drive assembly 111 or the second drive assembly 113 described above; this application does not limit the structural type of the third drive assembly 115.

[0074] In this embodiment, the first driving mechanism 11 is configured to also include a third driving component 115, such that the pressing member 13 can have a height difference with the member to be pressed in the first direction. Then, the third driving component 115 drives the pressing member 13 to approach and press against the member to be pressed in the first direction, thereby ensuring that the pressing member 13 does not interfere with the member to be pressed when it is being transported. In addition, the third driving component 115 is connected to the first driving component 111, and the second driving component 113 is connected to the third driving component 115, so that the third driving component 115 can be arranged below the second driving component 113, thereby facilitating that the pressing member 13 connected to the second driving component 113 can have a suitable height.

[0075] Of course, this application is not limited to this. In one embodiment of this application, the third drive component 115 may be connected to the second drive component 113, and the pressing member 13 may be connected to the third drive component 115. The third drive component 115 may be configured to drive the pressing member 13 to move along the first direction.

[0076] In one embodiment of this application, the pressing device 10 may further include a first guide structure to guide the movement of the first driving assembly 111 driving the third driving assembly 115, the second driving assembly 113, and the pressing member 13 along a second direction. The first guide structure may be configured as a slide rail and a slider, or it may be configured as a guide rod and a guide sleeve.

[0077] In one embodiment of this application, the pressing device 10 may further include a second guide structure to guide the movement of the pressing member 13 driven by the second driving assembly 113 in a third direction. This second guide structure may be configured as a slide rail and slider, or alternatively, as a guide rod and guide sleeve.

[0078] In one embodiment of this application, the pressing device 10 may further include a third guide structure to guide the movement of the third driving assembly 115 driving the second driving assembly 113 and the pressing member 13 along the first direction. This third guide structure may be configured as a slide rail and slider, or it may be configured as a guide rod and guide sleeve.

[0079] Please refer to the reference. Figure 1 and Figure 2 In one embodiment of this application, the pressing device 10 further includes a mounting plate 17, a first driving component 111 is disposed on one side of the mounting plate 17 in a first direction, and a position detection mechanism 15 is disposed on the other side of the mounting plate 17 in the first direction. The mounting plate 17 is provided with an exposure hole 1731, which penetrates both sides of the mounting plate 17 in the first direction and is configured to expose the part to be pressed.

[0080] When the first direction is vertical as described above, the first drive assembly 111 can be set on the lower side of the mounting plate 17, the position detection mechanism 15 can be set on the upper side of the mounting plate 17, and the exposure hole 1731 can penetrate through the upper and lower surfaces of the mounting plate 17 to expose the part to be pressed for the position detection mechanism 15 to perform position identification and detection.

[0081] In this embodiment, the first drive assembly 111 and the mounting plate 17 are respectively disposed on both sides of the mounting plate 17 in the vertical direction, so that the space on both sides of the mounting plate 17 can be fully utilized, reducing the overall volume of the pressing device 10. At the same time, the mounting plate 17 can also press against the carrier of the component to be pressed, for example, when the component to be pressed is a sealing nail for sealing the liquid injection hole as described above, the carrier can be an end cap with a liquid injection hole in the battery device, so that the sealing nail can be welded to the end cap more stably.

[0082] Please refer to the reference. Figure 1 , Figure 2 as well as Figure 8 In one embodiment of this application, the mounting plate 17 includes a first plate body 171 and a second plate body 173. A first drive assembly 111 is disposed on the first plate body 171. The second plate body 173 is connected to the first plate body 171. The second plate body 173 is provided with an exposure hole 1731. At least a portion of the second plate body 173 protrudes from the first plate body 171 and is disposed on the side facing the first drive assembly 111. The side of the second plate body 173 facing the first drive assembly 111 is also provided with a clearance groove 1733. The clearance groove 1733 extends along a third direction and is connected to the exposure hole 1731 at one end in the third direction, and penetrates the second plate body 173 at the other end. The clearance groove 1733 is configured to allow the pressing member 13 to extend into it.

[0083] The first plate 171 may have a mounting hole, and the second plate 173 is installed in the mounting hole, forming a structure in which the first plate 171 surrounds the second plate 173. Alternatively, the second plate 173 may be located on the side of the first plate 171 facing a third direction, forming a structure in which the second plate 173 and the first plate 171 are arranged along a third direction. At least a portion of the second plate 173 protrudes from the side of the first plate 171 facing the first drive assembly 111; that is, the lower surface of the second plate 173 protrudes from the lower surface of the first plate 171.

[0084] In this embodiment, the mounting plate 17 is configured to include a first plate 171 and a second plate 173, and the lower surface of the second plate 173 protrudes from the lower surface of the first plate 171. This allows the pressing member 13 to be positioned above the carrier when the carrier is pressed by the protruding second plate 173, facilitating its subsequent insertion through the groove 1733 into the exposure hole 1731 and downwards under the drive of the third drive assembly 115 to press against the carrier located below the exposure hole 1731.

[0085] In one embodiment of this application, the area of ​​the exposure hole 1731 can be larger than the area of ​​the part to be pressed, so that the part to be pressed can still be exposed through the exposure hole 1731 when it is conveyed to the position and deviates from the preset conveying position.

[0086] In one embodiment of this application, the cross-sectional width of the relief groove 1733 can be greater than the cross-sectional width of the pressing member 13 on the cross-section perpendicular to the third direction, so that when the member to be pressed deviates from the preset conveying position during the conveying, after the pressing member 13 moves and adjusts along the second direction, it can still correspond to the member to be pressed after passing through the relief groove 1733 and extending into the exposure hole 1731.

[0087] In one embodiment of this application, the second plate 173 is detachably connected to the first plate 171.

[0088] In this embodiment, the second plate 173 is configured as a detachable connection, allowing for the replacement of the appropriate size second plate 173 when mounting carriers of different sizes of components to be pressed, such as battery devices of different sizes, thereby improving the versatility of the pressing device 10. Of course, if the second plate 173 is damaged, it can also be easily replaced partially. The second plate 173 can be connected by screws, snap-fit ​​connections, or magnetic connections; this application does not limit the detachable connection method of the second plate 173. In some embodiments, the second plate 173 and the first plate 171 are configured as a non-detachable connection, such as an adhesive connection or a welded connection. Alternatively, in some embodiments, the second plate 173 and the first plate 171 can be configured as an integrally formed structure.

[0089] Please refer to the reference. Figures 1 to 5 In one embodiment of this application, the first driving mechanism 11 may further include a first carrier 117 and a second carrier 118. The first carrier 117 may be connected to the first driving component 111, and the third driving component 115 may be installed on the first carrier 117. The second carrier 118 may be connected to the third driving component 115, and the second driving component 113 may be installed on the second carrier 118.

[0090] The first carrier 117 can be a plate structure, a column structure, a combination of multiple plates, a combination of multiple columns, or a combination of plates and columns. This application does not limit the type of the first carrier 117. Similarly, the second carrier 118 can be a plate structure, a column structure, a combination of multiple plates, a combination of multiple columns, or a combination of plates and columns. This application does not limit the type of the second carrier 118.

[0091] In this embodiment, by setting the first carrier 117 and the second carrier 118, a connection structure is set up to facilitate the connection of the first drive component 111, the second drive component 113 and the third drive component 115.

[0092] In one embodiment of this application, to improve the compactness of the distribution between structures and the stability of installation, the first carrier 117 can be configured as a U-shaped structure with the opening facing upwards, forming an enclosed space in the middle. In this case, the two ends of the first carrier 117 forming the opening can be slidably mounted on the mounting plate 17 through the first guide mechanism as described above, and the first drive assembly 111 can be connected to one side wall of the first carrier 117; the third drive assembly 115 can be mounted on the bottom wall of the corresponding opening in the first carrier 117, so that the second carrier 118 connected to the upper end of the third drive assembly 115 and the second drive assembly 113 mounted on the second carrier 118 can be arranged in the enclosed space; the second carrier 118 can also be slidably mounted on the first carrier 117 through the third guide structure as described above.

[0093] In one embodiment of this application, to facilitate the pressing member 13 protruding from the third-party upward side of the first drive mechanism 11 so as to extend into the clearance groove 1733 of the mounting plate 17, the first drive mechanism 11 may further include a third carrier 119. The third carrier 119 can be connected to the second drive assembly 113 mounted on the second carrier 118, and the pressing member 13 can be mounted on the third-party upward end of the third carrier 119. Simultaneously, this arrangement also facilitates the sliding mounting of the third carrier 119 onto the second carrier 118 via the second guide structure described above.

[0094] Please refer to Figure 1 In one embodiment of this application, the pressing device 10 further includes a second driving mechanism 18, which is connected to the mounting plate 17 and configured to drive the mounting plate 17 to move at least along a first direction.

[0095] The second drive mechanism 18 can be used to drive the mounting plate 17 to move along the first direction, and can also be used to further drive the mounting plate 17 to move along the second and / or third directions. The second drive mechanism 18 can be a cylinder, or it can have the same structure as the first drive assembly 111 or the second drive assembly 113 described above, or it can be a robotic arm. This application does not limit the structural type of the second drive mechanism 18. Furthermore, to improve the compactness of the structure, the second drive mechanism 18 can be located on the side of the mounting plate 17 facing the position detection mechanism 15.

[0096] In this embodiment, by providing a second driving mechanism 18, the mounting plate 17 can be driven to descend and press against the carrier on which the component to be pressed is mounted. Thus, before the carrier is transported, the mounting plate 17 can form a height difference with the carrier, preventing interference with the transport of the carrier. Furthermore, this arrangement allows for adaptive pressing of carriers with different heights.

[0097] Please refer to Figure 1 In one embodiment of this application, the pressing device 10 further includes a third driving mechanism 19, which is connected to the position detection mechanism 15 and configured to drive the position detection mechanism 15 to move.

[0098] The third drive mechanism 19 can be used to drive the position detection mechanism 15 to move. The third drive mechanism 19 can be used to drive the position detection mechanism 15 to move along at least one of a first direction, a second direction, and a third direction. Alternatively, the third drive mechanism 19 can be a cylinder, or it can have the same structure as the first drive assembly 111 or the second drive assembly 113 described above, or it can be a robotic arm. This application does not limit the structural type of the third drive mechanism 19. Furthermore, to improve the compactness of the structure, the third drive mechanism 19 can be disposed on the side of the mounting plate 17 facing the position detection mechanism 15.

[0099] In this embodiment, by providing a third driving mechanism 19, the position detection mechanism 15 can be driven to move. When the position detection mechanism 15 and the second driving mechanism 18 described above are located on the same side of the mounting plate 17, they can move and avoid each other without easily interfering with each other. In addition, this arrangement allows the preset detection position of the position detection mechanism 15 to be adaptively adjusted according to the size of the carrier for mounting the component to be pressed.

[0100] In one embodiment of this application, the position detection mechanism 15 includes a CCD camera.

[0101] A CCD camera can be used to capture and identify the position information of the part to be pressed. For example, a preset detection position of the position detection mechanism 15 can be set in advance, and the part to be pressed can be captured as a template image. At this time, the CCD camera can identify the center of the part to be pressed in the template image based on visual detection technology, set it as the reference coordinate M(x1,y1) of the template image, and establish the correspondence between the image coordinate system and the actual spatial coordinate system of the pressing device 10. Then, in the actual operation process, when the part to be pressed is delivered to the position, the CCD camera can move to the preset detection position each time and capture the current image of the part to be pressed. At this point, the center of the component to be pressed in the current image is identified using visual detection technology and set as the current coordinate N(x2, y2) of the current image. The current coordinate N(x2, y2) of the current image is compared with the reference coordinate M(x1, y1) of the template image. Based on the correspondence between the image coordinate system and the spatial coordinate system, the coordinate Z(x3, y3) of the component to be pressed in the spatial coordinate system is calculated, which is the position information of the component to be pressed. The first driving mechanism 11 drives the pressing component 13 to move to this position, thus achieving correspondence with the component to be pressed. Here, X in the coordinate system can represent the position in one of the second direction and the third direction, and Y in the coordinate system can represent the position in the other of the second direction and the third direction.

[0102] In this embodiment, the position detection mechanism 15 is configured to include a CCD camera, which enables the use of high-precision visual positioning detection technology to identify and detect the part to be pressed, thereby improving the accuracy of the identification and detection of the position information of the part to be pressed.
