However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] See Figure 1 and Figure 2 , Figure 1 This is a perspective view of a terminal clamping device provided in an embodiment of this application. Figure 2 This is a top view of a terminal clamping device provided in an embodiment of this application.

[0034] An embodiment of this application provides a terminal flattening device, including a mounting bracket 100, a plurality of flattening mechanisms 200, and a power mechanism 300.

[0035] The mounting frame 100 can be a support structure composed of plates, rods or pipes, etc. For example, the mounting frame 100 is composed of multiple plates that are fixedly connected to each other.

[0036] The clamping mechanism 200 includes a fixed clamping finger 210 and a movable clamping finger 220. The fixed clamping finger 210 is fixedly connected to the mounting frame 100 and has a first clamping end 211. The movable clamping finger 220 is movably mounted on the mounting frame 100 and has a second clamping end 221. The movable clamping finger 220 has a first state in which the second clamping end 221 is close to the first clamping end 211 and a second state in which the second clamping end 221 is far away from the first clamping end 211.

[0037] The phrase "the second clamping end 221 is close to the first clamping end 211" means that the distance between the second clamping end 221 and the first clamping end 211 is small, so that when the terminal is located between the second clamping end 221 and the first clamping end 211, it can be flattened by both the second clamping end 221 and the first clamping end 211. The phrase "the second clamping end 221 is far from the first clamping end 211" means that the distance between the second clamping end 221 and the first clamping end 211 is larger than when the movable clamping finger 220 is in the first state, so that the terminal can smoothly enter or exit the gap between the first clamping end 211 and the second clamping end 221.

[0038] In this embodiment, the distance between the second clamping end 221 and the first clamping end 211 in the first and second states is not specifically limited, and can be flexibly selected according to the size of the terminal.

[0039] Furthermore, the movable gripper 220 being movably mounted on the mounting bracket 100 means that the movable gripper 220 is capable of moving relative to the mounting bracket 100, including but not limited to sliding along the mounting bracket 100 or rotating relative to the mounting bracket 100.

[0040] A power mechanism 300 is mounted on the mounting bracket 100 and connects to the movable gripping fingers 220 of multiple clamping mechanisms 200. It drives the movable gripping fingers 220 of the multiple clamping mechanisms 200 to switch between a first state and a second state. The aforementioned driving of the movable gripping fingers 220 between the first and second states includes, but is not limited to, driving the movable gripping fingers 220 to translate or rotate to switch states. The power mechanism 300 can drive the multiple movable gripping fingers 220 synchronously or asynchronously; that is, the multiple movable gripping fingers 220 can switch states simultaneously or separately.

[0041] In this embodiment, the power mechanism 300 can drive the second clamping end 221 of the movable clamping finger 220 in the multiple flattening mechanisms 200 to approach or move away from the first clamping end 211 of the fixed clamping finger 210, thereby realizing the simultaneous flattening of multiple terminals or multiple pairs of terminals, which can effectively improve production efficiency. In addition, the terminal flattening device in this embodiment has a relatively simple structure, which can ensure operational stability and maintain low operating costs while improving production efficiency.

[0042] In some embodiments, the power mechanism 300 includes a linkage structure 310 and a drive member 320. The linkage structure 310 is slidably mounted on the mounting bracket 100 and connected to the movable gripping fingers 220 of the clamping mechanism 200. The drive member 320 is mounted on the mounting bracket 100 and connected to the linkage structure 310. The drive member 320 is used to drive the linkage structure 310 to reciprocate, so that the movable gripping fingers 220 of the plurality of clamping mechanisms 200 switch between a first state and a second state.

[0043] The aforementioned linkage structure 310 is slidably mounted on the mounting frame 100. This can be achieved by having the linkage structure 310 fit snugly against the mounting frame 100, allowing the linkage structure 310 to slide along the mounting frame 100, or by providing a slide rail module between the linkage structure 310 and the mounting frame 100. No specific limitation is made here. For example, the mounting frame 100 includes a first plate 110, and multiple clamping mechanisms 200 and the linkage structure 310 are all arranged on the same side of the mounting frame 100. The linkage structure 310 is slidably connected to the mounting frame 100 via a slide rail module mounted on the same side of the mounting frame 100.

[0044] In this embodiment, the movable gripper 220 of the multiple clamping mechanisms 200 switches between the first state and the second state by driving the linkage structure 310 to slide back and forth through the driving component 320. Its structure and operation process are relatively simple, which is conducive to improving stability and reducing the cost of use.

[0045] Combination Figure 2 , Figure 3 and Figure 4 In some embodiments, the movable gripper 220 is rotatably connected to the mounting bracket 100, and the rotation axes 222 of the movable gripper 220 of the plurality of clamping mechanisms 200 are parallel to each other.

[0046] For example, the movable gripping fingers 220 of the multiple clamping mechanisms 200 are all rotatably connected to the mounting frame 100 via a rotating shaft 222 perpendicular to the first plate 110. One end of the movable gripping finger 220 serves as the second clamping end 221. The connection position between the rotating shaft 222 and the movable gripping finger 220 is located in the middle or near the middle of the movable gripping finger 220. The connection position between the rotating shaft 222 and the movable gripping finger 220 is located between the connection position of the second clamping end 221 and the power mechanism 300 and the second clamping end 221.

[0047] The rotation axis 222 of the movable gripping fingers 220 of the multiple clamping mechanisms 200 can all be located on the same side of the first plate 110, or they can be placed on both sides of the first plate 110. The fixed gripping fingers 210 and the movable gripping fingers 220 can be determined on which side of the first plate 110 they are located according to the position of the rotation axis 222.

[0048] In this embodiment, the state of the movable gripper 220 is adjusted by rotation. This method has a simple structure, high reliability, and leverage can increase the pressure of the second gripping end 221 on the terminal, achieving a better gripping effect. Furthermore, since the rotation axes 222 of the movable gripper 220 of the multiple flattening mechanisms 200 are parallel to each other, the spatial arrangement of the movable gripper 220, the fixed gripper 210, and the power mechanism 300 is more rational, reducing space occupation and making it more convenient to perform flattening operations on multiple terminals.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the linkage structure 310 includes a pushing component 311 and an elastic element 312. The pushing component 311 is slidably mounted on the mounting frame 100, connected to the driving component 320, and in contact with the movable gripper finger 220. The pushing component 311 is configured to push the movable gripper finger 220 to rotate when it slides toward the first direction X under the drive of the driving component 320, so that the second gripping end 221 is close to the first gripping end 211. The elastic element 312 is mounted on the mounting frame 100 and connected to the movable gripper finger 220. The elastic element 312 is configured to drive the movable gripper finger 220 to rotate and reset when the driving component 320 drives the pushing component 311 to slide toward the second direction Y, so that the second gripping end 221 is away from the first gripping end 211. The second direction Y is opposite to the first direction X.

[0050] The first direction X and the second direction Y are both parallel to the first plate 110 and perpendicular to the axis of rotation 222. The first direction X and the second direction Y are opposite in orientation. The driving member 320 can drive the pushing assembly 311 to slide towards the first direction X and the second direction Y, that is, the driving member 320 can drive the pushing assembly 311 to slide back and forth. When the driving member 320 drives the pushing assembly 311 to slide towards the first direction X, the pushing assembly 311 gradually approaches the rotation axis 222. The movable gripping finger 220 rotates under the drive of the pushing assembly 311, so that the second gripping end 221 of the movable gripping finger 220 gradually approaches the first gripping end 211 of the fixed gripping finger 210, that is, the movable gripping finger 220 switches from the second state to the first state to perform the terminal gripping operation. During this process, the elastic deformation of the elastic member 312 increases; the driving member When the push assembly 311 is slid towards the second direction Y, the push assembly 311 gradually moves away from the rotation axis 222. The elastic element 312 can provide a reset force for the movable gripper finger 220, so that the second gripping end 221 of the movable gripper finger 220 gradually moves away from the first gripping end 211 of the fixed gripper finger 210. That is, the movable gripper finger 220 switches from the first state to the second state, which facilitates the picking and putting of terminals, and keeps the movable gripper finger 220 in contact with the push assembly 311.

[0051] In some embodiments, the movable gripper finger 220 has a contact surface 223 that is parallel to the axis of the rotation shaft 222 and intersects the sliding direction of the pressing assembly 311. The pressing assembly 311 includes a slider 313, a mounting block 314, and a rolling element 315. The slider 313 is slidably mounted on the mounting bracket 100 and connected to the drive member 320. The slider 313 is adapted to reciprocate under the drive of the drive member 320. One end of the mounting block 314 is fixedly connected to the slider 313, and the other end points towards the movable gripper finger 220. The rolling element 315 is rotatably connected to the end of the mounting block 314 opposite to the slider 313 and rolls in contact with the contact surface 223.

[0052] In this embodiment, the contact surface 223 is a plane, and the angle between the contact surface 223 and the sliding direction (first direction X or second direction Y) of the slider 313 is an acute angle. The mounting block 314 is an elongated structure, and the extension direction of the mounting block 314 is parallel to or intersects the sliding direction of the slider 313. The mounting block 314 is adapted to move along the first direction X or the second direction Y under the drive of the slider 313. The rolling element 315 is rotatably mounted on the mounting block 314, so that the rolling element 315 can move synchronously with the mounting block 314. The axis of the rolling element 315 is parallel to the rotation axis 222 of the movable gripper finger 220, and the rolling element 315 rolls in contact with the contact surface 223. By setting the rolling element 315, it is beneficial to reduce the friction between the pushing assembly 311 and the movable gripper finger 220, making the rotation of the movable gripper finger 220 smoother. The rolling element 315 can be a bearing or a roller, etc., and is not specifically limited here.

[0053] In some other embodiments, the rolling element 315 may not be provided. That is, the end of the mounting block 314 away from the slider 313 can directly slide in contact with the contact surface 223 of the movable gripper finger 220, which can also achieve the driving function.

[0054] To make the push assembly 311 drive the movable gripper finger 220 to rotate more smoothly and to avoid dead spots, optionally, in the moving direction of the roller 315, the roller 315 is misaligned with the rotation axis 222 of the movable gripper finger 220. In other words, the rotation axis 222 of the movable gripper finger 220 is located outside the extension line of the moving path of the roller 315.

[0055] In other embodiments, such as Figure 4 As shown, the linkage structure 310 includes a first link 316 and a second link 317. The first link 316 is connected to the drive member 320. One end of the second link 317 is hinged to the first link 316, and the other end is hinged to the movable gripper finger 220. The rotation axis 222 of the movable gripper finger 220 is located between the connection position of the second link 317 and the movable gripper finger 220 and the second gripping end 221.

[0056] For example, the first link 316 extends along the first direction X, one end of the first link 316 is fixedly connected to the movable end of the drive member 320, the other end of the first link 316 is hinged to one end of the second link 317, the extension direction of the second link 317 intersects the first direction X, the end of the second link 317 away from the first link 316 is hinged to the movable gripper finger 220, and the second link 317 and the movable gripper finger 220 are set at an angle.

[0057] When the driving member 320 drives the first link 316 to move in the first direction X or the second direction Y, the first link 316 transmits power to the movable gripper finger 220 via the second link 317, thereby driving the movable gripper finger 220 to rotate and switching the movable gripper finger 220 between the first state and the second state. Specifically, when the driving member 320 drives the first link 316 to move in the first direction X, the movable gripper finger 220 is rotated via the second link 317, enabling the movable gripper finger 220 to switch from the second state to the first state. When the driving member 320 drives the first link 316 to move in the second direction Y, the movable gripper finger 220 is rotated in the opposite direction via the second link 317, enabling the movable gripper finger 220 to switch from the first state to the second state.

[0058] The above embodiment is described using the example of the movable gripper 220 being rotatably connected to the mounting bracket 100. It can be understood that the movable gripper 220 can also switch states by translation.

[0059] For example Figure 5 As shown, the movable gripper 220 is slidably connected to the mounting bracket 100, and the linkage structure 310 is fixedly connected to the movable gripper 220. The arrangement direction of the movable bracket and the fixed bracket is parallel to the sliding direction of the linkage structure 310. When the driving member 320 drives the linkage structure 310 to slide along the first direction X or the second direction Y, it can drive the movable bracket to slide along the first direction X or the second direction Y, so as to switch between the first state and the second state.

[0060] Understandably, the number of terminals varies depending on the product type, and the number of terminals that each clamping mechanism 200 needs to clamp varies when performing terminal clamping operations on a product.

[0061] For example, when each product has one terminal, each clamping mechanism 200 may be provided with only one fixed clamping finger 210 and one movable clamping finger 220.

[0062] Alternatively, when each product has two terminals, each clamping mechanism 200 can be provided with two fixed clamping fingers 210 and two movable clamping fingers 220, with a one-to-one correspondence between the fixed clamping fingers 210 and the movable clamping fingers 220.

[0063] The following description uses the example of each clamping mechanism 200 having two fixed clamping fingers 210 and two movable clamping fingers 220.

[0064] As an optional approach, combined Figure 2 and Figure 3The movable gripper 220 is rotatably connected to the mounting bracket 100. The two fixed grippers 210 and the two movable grippers 220 of each clamping mechanism 200 are symmetrical about the first plane M. When the two movable grippers 220 of the clamping mechanism 200 switch between the first state and the second state, they rotate in opposite directions.

[0065] For example, the two movable fingers 220 and the two fixed fingers 210 are symmetrical about a plane perpendicular to the first plate 110. The two fixed fingers 210 are located between the two movable fingers 220, or the two fixed fingers 210 are located outside the two movable fingers 220. Preferably, the two fixed fingers 210 are located outside the two movable fingers 220.

[0066] The two movable gripping fingers 220 and two fixed gripping fingers 210 of the clamping mechanism 200 are symmetrical about the first plane M. By rotating the two movable gripping fingers 220 in opposite directions, their state switching methods can be made identical. Taking the two fixed gripping fingers 210 located outside the two movable gripping fingers 220 as an example, when one movable gripping finger 220 rotates in one direction (e.g., clockwise), causing its second gripping end 221 to move away from the first plane M, and the other movable gripping finger 220 rotates in the opposite direction (e.g., counterclockwise), causing its second gripping end 221 to move away from the first plane M, the second gripping ends 221 of both movable gripping fingers 220 approach the first gripping ends 211 of their corresponding fixed gripping fingers 210. Therefore, both movable gripping fingers 220 can... Switching from the second state to the first state: When one of the movable gripping fingers 220 rotates in one direction (e.g., counterclockwise) so that the second gripping end 221 of the movable gripping finger 220 is close to the first plane M, and the other movable gripping finger 220 rotates in the opposite direction (e.g., clockwise) so that the second gripping end 221 of the movable gripping finger 220 is close to the first plane M, the second gripping ends 221 of both movable gripping fingers 220 are moved away from the first gripping end 211 of their corresponding fixed gripping fingers 210. Therefore, both movable gripping fingers 220 can switch from the first state to the second state.

[0067] It is worth noting that the first plane M is a symmetrical plane between the two fixed clamping fingers 210 and between the two movable clamping fingers 220, and is not limited to one. For example, when there are multiple clamping mechanisms 200, each clamping mechanism 200 can correspond to a first plane M.

[0068] For example, combined Figure 1 and Figure 2In the case where the power mechanism 300 includes a linkage structure 310 and a drive member 320, and the linkage structure 310 includes a pressing assembly 311 and an elastic member 312, both movable gripping fingers 220 are connected to the pressing assembly 311 and the elastic member 312. Specifically, the pressing assembly 311 includes two mounting blocks 314, both of which are fixedly connected to the slider 313, and the two mounting blocks 314 are slidably engaged with the two movable gripping fingers 220 of the same clamping mechanism 200 in a one-to-one correspondence. Further, the pressing assembly 311 also includes two rolling members 315, which are disposed on the two mounting blocks 314 and are in rolling contact with the two movable gripping fingers 220 of the same clamping mechanism 200 in a one-to-one correspondence. The contact positions of the two rolling elements 315 with the corresponding movable gripper fingers 220 are both on the side of the movable gripper fingers 220 away from the other movable gripper fingers 220 in the flattening mechanism 200. That is, the contact surfaces 223 of the two movable gripper fingers 220 in the same flattening mechanism 200 are located on opposite sides of the two movable gripper fingers 220. Further, the elastic element 312 includes a first compression spring, which is located between the two movable gripper fingers 220 of the flattening mechanism 200 and is connected to the two movable gripper fingers 220 respectively. When both movable gripper fingers 220 switch to the first state, the first compression spring is compressed; when both movable gripper fingers 220 switch to the second state, the first compression spring is extended.

[0069] In this embodiment, the first compression spring connects both movable fingers 220 simultaneously. The reset requirements of both movable fingers 220 can be met by a single compression spring, simplifying the structure of the terminal clamping device and improving its stability. Furthermore, the first compression spring provides equal force to both movable fingers 220, which helps ensure the synchronicity of their movements.

[0070] For example, combined Figure 4 The power mechanism 300 includes a linkage structure 310, which includes a first link 316 and a second link 317. Two second links 317 are provided in the linkage structure 310, each hinged to the first link 316, and each hinged to a corresponding movable gripper finger 220. Therefore, when the drive member 320 drives the first link 316 to move along the first direction X or the second direction Y, the two second links 317 can simultaneously drive the two movable gripper fingers 220 to rotate, thus achieving state switching between the two movable gripper fingers 220.

[0071] Furthermore, the first link 316 and the second link 317 are symmetrically arranged about the first plane M, and the first link 316 and the second link 317 are hinged to the movable finger 220 on the same side of the two movable fingers 220 that are symmetrical about the first plane M.

[0072] As another alternative approach, combined Figure 3 The movable gripper 220 is rotatably connected to the mounting bracket 100. The fixed gripper 210 and the movable gripper 220 are arranged alternately. When the two movable grippers 220 of the clamping mechanism 200 switch between the first state and the second state, they rotate in the same direction.

[0073] The movable gripper 220 corresponds to one of the adjacent fixed grippers 210. The two movable grippers 220 are oriented in the same direction, and when they rotate in the same direction, the second gripping ends 221 of the two movable grippers 220 swing in the same direction. Therefore, the second gripping ends 221 of the two movable grippers 220 are either close to or far away from the first gripping ends 211 of the corresponding fixed gripper 210.

[0074] For example, when the power mechanism 300 includes a linkage structure 310 and a drive member 320, and the linkage structure 310 includes a pressing assembly 311 and an elastic member 312, both movable gripper fingers 220 are connected to the pressing assembly 311 and the elastic member 312.

[0075] Specifically, the pushing assembly 311 includes two mounting blocks 314 and two rolling elements 315. Both mounting blocks 314 are fixedly connected to the slider 313. The two rolling elements 315 are positioned on the two mounting blocks 314 and roll in contact with the two movable gripping fingers 220 of the same clamping mechanism 200 in a one-to-one rolling contact. The contact surfaces 223 of the two movable gripping fingers 220 in the same clamping mechanism 200 are located on the same side of the two movable gripping fingers 220.

[0076] Furthermore, the elastic element 312 includes a second compression spring, and each movable gripper finger 220 is correspondingly connected to a second compression spring.

[0077] As another alternative approach, combined Figure 5 The linkage structure 310 and the movable clamping finger 220 are both slidably connected to the mounting frame 100. The fixed clamping finger 210 and the movable clamping finger 220 are arranged alternately, and the arrangement direction of the fixed clamping finger 210 and the movable clamping finger 220 is parallel to the sliding direction of the movable clamping finger 220. Both movable clamping fingers 220 of the clamping mechanism 200 are fixedly connected to the linkage structure 310.

[0078] When the linkage structure 310 slides along the first direction X or the second direction Y under the drive of the driving member 320, it can drive the two movable gripping fingers 220 in the clamping mechanism 200 to slide synchronously along the first direction X or the second direction Y, thereby moving closer to or away from the corresponding fixed gripping finger 210, and realizing the switching of the two movable gripping fingers 220 between the first state and the second state.

[0079] It is understood that the number of linkage structures 310 and driving components 320, as well as the number of driving components 320 and clamping mechanisms 200, can be the same or different. For example, multiple linkage structures 310 and multiple driving components 320 can be provided, with each linkage structure 310 correspondingly connected to one clamping mechanism 200 and one driving component 320. Alternatively, one linkage structure 310 can be provided, and multiple driving components 320 can be provided, with the linkage structure 310 simultaneously connected to multiple clamping mechanisms 200 and multiple driving components 320. Or, one linkage structure 310 and one driving component 320 can be provided, with the linkage structure 310 simultaneously connected to multiple clamping mechanisms 200.

[0080] Preferably, multiple driving components 320, linkage structures 310, and clamping mechanisms 200 are provided, with each linkage structure 310 correspondingly connected to one clamping mechanism 200 and one driving component 320. Thus, each clamping mechanism 200 can independently switch states under the drive of its corresponding driving component 320 and linkage structure 310. This allows the terminal clamping device of this embodiment to flexibly select the number and position of the clamping mechanisms 200 participating in the clamping action according to actual working needs, resulting in better applicability.

[0081] like Figure 2 As shown, in some embodiments, the drive member 320 includes a telescopic member 321 and a connector 322. The telescopic end of the telescopic member 321 is connected to one end of the connector 322, and the other end of the connector 322 is detachably connected to the linkage structure 310.

[0082] The telescopic component 321 can be a telescopic motor, cylinder, etc., without specific limitations.

[0083] For example, the mounting bracket 100 further includes a second plate 120 that is perpendicularly fixed to the first plate 110. The second plate 120 has a through hole, and the telescopic member 321 is fixedly installed at the through hole, with the telescopic end of the telescopic member 321 passing through the through hole. The telescopic end of the telescopic member 321 is fixedly connected to one end of the connector 322 by means of, for example, threaded connection or welding. The end of the connector 322 opposite to the telescopic member 321 is provided with a T-shaped portion, and the slider 313 is provided with a T-shaped groove. The T-shaped portion is located in the T-shaped groove, and the T-shaped groove forms an opening on at least one side in the thickness direction of the slider 313, through which the T-shaped portion can enter and exit the T-shaped groove.

[0084] Connector 322 can be a movable connector or a quick-release connector, etc., and all of them should be within the protection scope of the embodiments of this application.

[0085] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0086] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
