[0048] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0049] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0050] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0051] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, 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 embodiment.

[0054] During the production process of electronic product accessories, the products need to be transferred to the anode rack for fixation.

[0055] like Figure 1 and Figure 2 As shown, the product is used as the part to be clamped 200. In order to achieve the transfer of the part to be clamped 200, the transfer equipment provided in this embodiment includes a transfer device (not shown) and a clamping device 100. The clamping device 100 is used to pick up and place the part to be clamped 200, and the transfer device is used to transfer the clamping device 100 to a specified position to transfer the part to be clamped 200 to the specified position. The specified position can be an anode hanger or other position to which the part to be clamped 200 needs to be transferred.

[0056] Optionally, the transfer device can be any existing robotic arm. Figure 1 As shown, the material clamping device 100 includes a mounting frame 10 and a connecting mechanism 60. The connecting mechanism 60 is disposed on the mounting frame 10 and is used to connect to the transfer device. Optionally, the connecting mechanism 60 can be a pin that is plugged into and fixed to the output end of the adapter device. In other embodiments, the connecting mechanism 60 can also be a snap-fit structure, etc., as long as it can achieve a detachable connection with the output end of the transfer device.

[0057] Usually, the number of products that need to be transferred is very large, and the existing clamping device cannot clamp multiple products at the same time, resulting in low transfer efficiency.

[0058] In order to solve the above problems, Figure 1-Figure 3As shown, the transfer device provided in this embodiment includes a mounting frame 10, a driving mechanism 20 and a plurality of clamping mechanisms 30. The driving mechanism 20 is arranged on the mounting frame 10. The driving mechanism 20 includes a driving member 21 and a plurality of transmission members 22. The driving member 21 can output a linear motion in a vertical direction. The plurality of transmission members 22 are arranged at the output end of the driving member 21. The plurality of clamping mechanisms 30 are all arranged at the output end of the transmission member 22. Two adjacent transmission members 22 cooperate with the clamping mechanism 30 to convert the linear motion in the vertical direction output by the driving member 21 into a horizontal motion in a first direction, so that the clamping mechanism 30 clamps the object to be clamped 200. By clamping the object to be clamped 200 by multiple clamping mechanisms 30, the transfer efficiency of the object to be clamped 200 can be improved, and the degree of automation is relatively high. The driving force of the driving member 21 is transmitted to the clamping mechanism 30 by two adjacent transmission members 22, so that the clamping mechanism 30 clamps the object to be clamped 200. The structural design is ingenious, the integration is high, the overall volume of the clamping device is reduced, and the equipment installation space is saved. The driving member 21 may be a cylinder.

[0059] Specifically, if Figures 1-6 As shown, the clamping mechanism 30 includes two clamping jaws 31, at least one of which is provided with a first inclined surface 311. The transmission member 22 is provided with at least one second inclined surface 221 that matches the first inclined surface 311. The first inclined surface 311 abuts the second inclined surface 221. The driving member 21 drives the transmission member 22 downward in a vertical direction, so that the two clamping jaws 31 approach each other in a first direction. When it is necessary to clamp the object 200 to be clamped, the driving member 21 drives the transmission member 22 downward in a vertical direction, and the transmission member 22 drives the clamping jaws 31 toward each other in the first direction, so that the clamping jaws 31 clamp the object 200 to be clamped.

[0060] like Figure 2-Figure 4 As shown, the lower end of the transmission member 22 is provided with two second inclined surfaces 221, so that the transmission member 22 can simultaneously drive the clamping jaw 31 located in the middle position and the clamping jaw 31 of another adjacent clamping mechanism 30 disposed opposite thereto to move simultaneously, thereby improving the integration of the material clamping device 100. The number of transmission members 22 provided only needs to be one more than the number of clamping mechanisms 30. For example, Figure 1-Figure 3 As shown, in this embodiment, the number of clamping mechanisms 30 is six, the number of corresponding clamping jaws 31 is twelve, and the number of transmission members 22 is set to seven. In other embodiments, the number of clamping mechanisms 30 can also be two, three, or more, which can be adaptively adjusted according to actual needs.

[0061] Alternatively, as Figure 2 and Figure 7As shown, the drive mechanism 20 also includes a second guide member 23, which is mounted on the mounting frame 10. The second guide member 23 is provided with a first guide hole 231 extending vertically. The transmission member 22 is inserted into and slides along the first guide hole 231. The second guide member 23 ensures that the transmission member 22 moves vertically, preventing it from shifting during movement. Specifically, the first guide hole 231 is a through hole, allowing the lower end of the transmission member 22 to extend beyond the second guide member 23, thereby transmitting the driving force of the driver 21 to the clamping jaw 31.

[0062] Alternatively, as Figure 1-Figure 3 As shown, the clamping device 100 also includes a second elastic return member 50, disposed between the second guide member 23 and the transmission member 22. The second elastic return member 50 is configured to vertically elevate the transmission member 22. Once the clamping jaws 31 have released the material from the clamped member 200, the output end of the driver 21 rises, and the transmission member 22, under the action of the second elastic return member 50, rises, completing the reset action. Specifically, the second elastic return member 50 is a spring.

[0063] Alternatively, as Figure 2 and Figure 7 As shown, the second guide member 23 is provided with a second guide hole 232 extending in the vertical direction, and at least a portion of the second elastic return member 50 is located in the second guide hole 232. Specifically, the second guide hole 232 is a blind hole, so that one end of the second elastic return member 50 abuts against the second guide member 23 and the other end abuts against the transmission member 22. The second guide hole 232 guides the second elastic return member 50, ensuring the accuracy of the elastic force provided by the second elastic return member 50.

[0064] like Figure 2-Figure 4 As shown, the clamping device 100 further includes a second stopper 24, which is disposed on the mounting frame 10. The transmission member 22 is provided with a second stopper hole 222 extending in the vertical direction, and at least a portion of the second stopper 24 is located within the second stopper hole 222. When the transmission member 22 moves downward in the vertical direction, the second stopper 24 allows the transmission member 22 to move only within the vertical length range of the second stopper hole 222, thereby preventing the transmission member 22 from excessively traveling and causing excessive clamping force of the clamping jaws 31, which could damage the clamped object 200.

[0065] Alternatively, as Figure 2 、 Figure 3 and Figure 5As shown, a first elastic return member 40 is disposed between the two clamping jaws 31 to force the two clamping jaws 31 away from each other in a first direction. When the material to be clamped 200 needs to be released, the transmission member 22 moves upward in the vertical direction under the action of the second elastic return member 50. The clamping jaws 31 move away from each other in the first direction under the elastic force of the first elastic return member 40, thereby releasing the material to be clamped 200. Specifically, the first elastic return member 40 can be a spring.

[0066] Alternatively, as Figure 2 、 Figure 5 and Figure 6 As shown, the clamping jaw 31 defines a third guide hole 315 extending along the first direction, and at least a portion of the first elastic return member 40 is located within the third guide hole 315. The third guide hole 315 is a blind hole, allowing both ends of the first elastic return member 40 to abut against the corresponding clamping jaw 31. The third guide hole 315 guides the first elastic return member 40, ensuring the accuracy of the elastic force provided by the first elastic return member 40 and facilitating installation of the first elastic return member 40.

[0067] like Figure 2 、 Figure 5 and Figure 6 As shown, the clamping mechanism 30 further includes a first stopper 33, which is disposed on the mounting frame 10. The clamping jaws 31 are provided with a first stopper hole 313 extending in a first direction, with at least a portion of the first stopper 33 located within the first stopper hole 313. When the two clamping jaws 31 approach each other in the first direction, the first stopper 33 restricts the clamping jaws 31 to movement within the length of the first stopper hole 313 in the first direction, thereby preventing the clamping force of the two clamping jaws 31 from damaging the clamped object 200.

[0068] like Figure 5 and Figure 6 As shown, a flexible part 34 is provided on one side of the clamping jaw 31 close to the part to be clamped 200. The flexible part 34 can deform within a certain range to prevent the clamping difference caused by the error of the part to be clamped 200; at the same time, it further prevents the clamping jaw 31 from damaging the part to be clamped 200.

[0069] Exemplarily, the part to be clamped 200 is an injection-molded part, and an injection-molded protrusion cut is left at at least one end of the part to be clamped 200 along the first direction. In order to avoid the injection-molded protrusion cut affecting the clamping of the part to be clamped 200 by the clamping jaw 31, an avoidance groove 314 is provided on at least one clamping jaw 31 of the clamping mechanism 30 to avoid the injection-molded protrusion cut on the part to be clamped 200.

[0070] Since the distance between two adjacent positions of the anode rack for fixing product models is very small (generally 21 mm), the existing clamping device cannot clamp multiple products with such a small distance.

[0071] In order to solve the above problem, the sum of the thicknesses of the two clamping jaws 31 along the first direction is less than 21 mm, so that the clamping device 100 can transfer the parts 200 to be clamped with a smaller spacing.

[0072] like Figure 2 and Figure 8 As shown, the clamping mechanism 30 further includes a first guide member 32 having a guide slot 321 extending in a first direction. The clamping jaw 31 includes a guide portion 312 that is inserted into and slides along the guide slot 321. When the driving member 21 drives the transmission member 22 to move the clamping jaw 31, the guide portion 312 slides along the guide slot 321, guiding the clamping jaw 31 in the first direction, thereby enabling the clamping jaw 31 to accurately clamp the object 200.
