[0028] The embodiment of the present application provides a pressing device, which is used to apply pressure. Exemplarily, pressure can be applied to parts or products, etc., so that the parts or products can be stably held in a certain position during processing, inspection, assembly and other links, and the production process can proceed smoothly.

[0029] Please refer to Figure 1 and Figure 2 , the pressing device provided by the embodiment of the present application includes a base 01, a mounting member 02, a pressing member 03, a first driving mechanism 04 and a second driving mechanism 05. The mounting member 02 is movably connected to the base 01; the pressing member 03 is rotatably connected to the base 01 with the first axis a as the axis; the first driving mechanism 04 is rotatably connected to the mounting member 02 and the pressing member 03, and the axes of relative rotation are all parallel to the first axis a; the output end of the second driving mechanism 05 is in transmission connection with the mounting member 02 to drive the mounting member 02 to move relative to the base 01; wherein, in the first driving mechanism 04 and the second driving mechanism 05, one of them is used to drive the pressing member 03 to rotate a first angle relative to the base 01 to move from the first position to the second position, and the other is used to drive the pressing member 03 to rotate a second angle relative to the base 01 to move from the second position to the third position, and the second angle is less than the first angle.

[0030] In this way, the pressing member 03 rotates relative to the base 01 by a first angle to move from the first position to the second position, so as to apply pressure to the target structure. The pressing member 03 rotates relative to the base 01 by a second angle to move from the second position to the third position. The second angle is smaller than the first angle, so that when the pressing member 03 applies pressure to the target structure, the attitude of the pressing member 03 relative to the target structure can be slightly adjusted, that is, the pressure between the pressing member 03 and the target structure can be adjusted. Therefore, in the present application, by controlling the first driving mechanism 04 and the second driving mechanism 05, the magnitude of the pressure applied by the pressing device can be conveniently adjusted, which is beneficial to meeting diverse production requirements, and the adaptability of the pressing device is relatively high.

[0031] Moreover, in the embodiment of the present application, the pressing member 03 is rotatably connected to the base 01, and the pressing member 03 rotates relative to the base 01 to apply pressure to the target structure. The connection between the pressing member 03 and the base 01 is relatively simple and convenient, which is beneficial to making the installation of the pressing member 03 relatively stable and beneficial to improving the reliability of the pressure applied by the pressing member 03. The first driving mechanism 04 is rotatably connected to the mounting member 02 and the pressing member 03, and the axes of relative rotation are all parallel to the first axis a. The connection manner of the first driving mechanism 04 with the mounting member 02 and the pressing member 03 is relatively simple and reliable. The first driving mechanism 04 can make the pressing member 03 rotate relative to the base 01 by pushing and pulling the pressing member 03, and the output force of the first driving mechanism 04 can stably act on the pressing member 03, with relatively high reliability. The output end of the second driving mechanism 05 is in transmission connection with the mounting member 02 to drive the mounting member 02 to move relative to the base 01, so that the pressing member 03 rotates relative to the base 01 by a second angle, that is, through the second driving mechanism 05, the distance between the axis of relative rotation of the first driving mechanism 04 relative to the mounting member 02 and the first axis a can be adjusted, so that the pose of the pressing member 03 relative to the base 01 can be adjusted, and the adjustment process is relatively convenient, and the structure is simple and reliable.

[0032] Please refer to Figure 1 and Figure 2 It should be noted that in the embodiment of the present application, the target structure is located on one side of the first axis a and is circumferentially arranged with the pressing member 03 along the first axis a. During the rotation of the pressing member 03 relative to the base 01, the pressing member 03 applies pressure to the target structure. In some embodiments of the present application, the first axis a can be perpendicular to the vertical direction. In this way, it is convenient for the processing and manufacturing of the pressing device. On this basis, in some embodiments of the present application, the target structure is located below the pressing member 03. In this way, it is convenient for the arrangement of the target structure.

[0033] Please refer to Figure 1 and Figure 2, in some embodiments of the present application, the base 01 includes a base 012 and a column 013. The base 012 is used to be placed on a support surface such as the ground or a tabletop. The column 013 is fixed to the upper end of the base 012. The pressing member 03 is rotatably connected to the upper end of the column 013. In this way, the installation of the pressing member 03 is relatively stable.

[0034] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the pressing member 03 and the base 01 form a lever mechanism. The end of the pressing member 03 connected to the first driving mechanism 04 is the power arm, and the end of the first driving mechanism 04 for applying pressure to the target structure is the resistance arm. In this way, the target structure and the first driving mechanism 04 can be respectively arranged on both sides of the first axis a, which is beneficial to reducing interference. Among them, the lever mechanism can be a labor-saving lever, a labor-consuming lever or an equal-arm lever, etc., which are not limited in the embodiments of the present application.

[0035] Please refer to Figure 1 and Figure 2 , in the embodiments of the present application, the axis of the first driving mechanism 04 rotating relative to the mounting member 02 refers to the second axis b in the figure, and the axis of the first driving mechanism 04 rotating relative to the pressing member 03 refers to the third axis c in the figure. It can be understood that the first axis a, the second axis b and the third axis c are parallel to each other in pairs. Under the driving action of the first driving mechanism 04, the pressing member 03 rotates relative to the first driving mechanism 04 and also relative to the base 01. During this process, the first driving mechanism 04 rotates relative to the pressing member 03.

[0036] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, a mounting shaft 021 is provided on the mounting member 02, and the first driving mechanism 04 is rotatably connected to the mounting member 02 through the mounting shaft 021. In this way, the structure is relatively simple and the cost is relatively low.

[0037] Please refer to Figure 1 and Figure 2 , in the embodiments of the present application, it can be understood that during the process of the mounting member 02 moving relative to the base 01, the distance between the first axis a and the third axis c changes. The mounting member 02 drives the first driving mechanism 04 to move relative to the base 01, so that the first driving mechanism 04 drives the pressing member 03 to rotate relative to the mounting member 02. During this process, the first driving mechanism 04 rotates relative to the mounting member 02, and the pressing member 03 rotates relative to the first driving mechanism 04.

[0038] Please refer to Figure 1 and Figure 2, for the sake of easy understanding, the principle of the movement of the mounting member 02 relative to the base 01 to cause the pressing member 03 to rotate relative to the base 01 is described below. The first line segment, the second line segment and the third line segment together enclose a triangle. The first line segment is the perpendicular line segment between the first axis a and the second axis b. The second line segment is the perpendicular line segment between the second axis b and the third axis c. The third line segment is the perpendicular line segment between the first axis a and the third axis c. When the mounting member 02 moves relative to the base 01, the length of the third line segment changes, and the lengths of the first line segment and the second line segment can remain unchanged, so that the angle between the first line segment and the third line segment changes, that is, the pressing member 03 rotates relative to the base 01.

[0039] It can be understood that in the embodiment of the present application, the first driving mechanism 04 is used to change the length of the second line segment so that the pressing member 03 rotates relative to the base 01 by a first angle.

[0040] Exemplarily, please refer to Figure 3 , in some embodiments of the present application, the first driving mechanism 04 includes a mounting member connecting portion and a pressing member connecting portion. The mounting member connecting portion is rotatably connected to the mounting member 02, and the pressing member connecting portion is rotatably connected to the pressing member 03. The mounting member connecting portion and the pressing member connecting portion are slidably connected, and the relative sliding direction is perpendicular to the first direction f. With such a structural form, the mounting member connecting portion and the pressing member connecting portion are slidably connected, and the connection between the mounting member connecting portion and the pressing member connecting portion is simple and reliable. During the relative sliding of the mounting member connecting portion and the pressing member connecting portion, the first connecting portion pushes and pulls the pressing member 03 to cause the pressing member 03 to rotate relative to the mounting member 02, and the process of driving the pressing member 03 to rotate relative to the base 01 is more conveniently realized.

[0041] Please refer to Figure 3 , in some embodiments of the present application, the first driving mechanism 04 can be a linear motor or a cylinder, etc. In this way, the cost is relatively low.

In such a structural form, the first driving member 043 drives the rotation of the pressing member 03 by driving the rotation of the first connecting rod 041, and the rotation amplitude of the pressing member 03 relative to the base 01 can be relatively freely controlled by controlling the lengths of the first connecting rod 041, the second connecting rod 042, and the pressing member 03, which is beneficial to improving the adaptability of the pressing device.

[0043] Please refer to Figure 1 and Figure 2 , In the embodiment of the present application, the axis of rotation of the first end of the first connecting rod 041 relative to the mounting member 02 is the third axis c, the axis of rotation of the first end of the second connecting rod 042 relative to the mounting member 02 is the second axis b, and the axis of relative rotation of the second end of the first connecting rod 041 and the second end of the first connecting rod 041 is the fourth axis d in the figure. It can be understood that the first axis a, the second axis b, the third axis c, and the fourth axis d are parallel to each other in pairs. The pressing member 03, the first connecting rod 041, the second connecting rod 042, the mounting member 02, and the base 01 together form a four-bar linkage mechanism. The base 01 and the mounting member 02 together serve as the frame, the pressing member 03 and the first connecting rod 041 are respectively two connecting rods. During the rotation of the first connecting rod 041 relative to the mounting member 02, the pressing member 03 rotates relative to the base 01.

In such a structural form, the connection manner of the first driving member 043 with the first connecting rod 041 and the base 01 is relatively simple and reliable. The first driving member 043 can make the first connecting rod 041 rotate relative to the base 01 by pushing and pulling the first connecting rod 041, and the output force of the first driving member 043 can stably act on the first connecting rod 041, with high reliability.

[0045] Please refer to Figure 1 and Figure 2, in the embodiments of the present application, the axis of rotation of the first driving member 043 relative to the base 01 refers to the fifth axis e in the figure. It can be understood that the axis of rotation of the first driving member 043 relative to the first connecting rod 041 is parallel to the fifth axis e.

[0046] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the first driving member 043 includes a first connecting portion and a second connecting portion. The first connecting portion is rotatably connected to the first connecting rod 041, and the second connecting portion is rotatably connected to the base 01. Along the first direction f, the first connecting portion and the second connecting portion are slidably connected, and the first direction f is perpendicular to the first axis a. With such a structural form, the first connecting portion and the second connecting portion are slidably connected, and the connection between the first connecting portion and the second connecting portion is simple and reliable. During the relative sliding process of the first connecting portion and the second connecting portion, the first connecting portion pushes and pulls the first connecting rod 041, causing the first connecting rod 041 to rotate relative to the mounting member 02, and the process of driving the first connecting rod 041 to rotate relative to the mounting member 02 is more conveniently realized.

[0047] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the first driving member 043 can be a linear motor or a cylinder, etc. In this way, the cost is relatively low. Exemplarily, in some embodiments of the present application, the first driving member 043 is a cylinder. The piston rod of the first driving member 043 is the first connecting portion, and the piston cylinder of the first driving member 043 is the second connecting portion. It can be that the piston rod of the first driving member 043 switches from the extended state to the retracted state, and the pressing member 03 rotates from the first position to the second position to press the target structure. It can also be that the piston rod of the first driving member 043 switches from the retracted state to the extended state, and the pressing member 03 rotates from the first position to the second position to press the target structure.

[0048] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the base 01 includes a cylinder seat 015, the first driving member 043 is rotatably connected to the cylinder seat 015, and the cylinder seat 015 and the base 012 are of a split structure. In this way, the structure is relatively simple and the processing and manufacturing are more convenient.

[0049] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the axis of rotation of the first driving member 043 relative to the first connecting rod 041 is the same as the axis of rotation of the first connecting rod 041 relative to the second connecting rod 042.

With such a structural form, the connection manner between the mounting member 02 and the base 01 is simple and reliable, and the movement of the mounting member 02 relative to the base 01 is also relatively stable, which is beneficial to improving the reliability of the pressing device.

[0051] Please refer to Figure 4 , in some other embodiments of the present application, the mounting member 02 may also be rotatably connected to the base 01, and the axis of relative rotation of the mounting member 02, the first axis a, the second axis b, and the third axis c are pairwise parallel.

The elastic direction of the elastic member 13 is the second direction g, and the elastic member 13 is used to drive the mounting member 02 to move in the direction close to the cam 051. With such a structural form, by providing the elastic member 13, the mounting member 02 can stably abut against the cam 051. When the cam 051 rotates relative to the base 01, the mounting member 02 can preferably maintain the position in contact with the cam 051 and is not easily separated from the cam 051 under the impact of the cam 051. The rotation of the cam 051 relative to the base 01 can finely adjust the position of the mounting member 02, which is beneficial to improving the adjustment accuracy during the adjustment of the pressure applied to the pressing member 03.

In such a structural form, the first driving member 043 drives the cam 051 according to the output signal of the pressure sensor 08, so that the pressure applied by the pressing member 03 can be finely adjusted according to the output signal of the pressure sensor 08, a closed-loop control can be formed, and the pressure can be adjusted in real time, which is beneficial to improving the adaptability of the pressing device.

[0059] Please refer to Figure 1 and Figure 2, in some embodiments of the present application, the second driving member 052 is a motor, a connecting shaft 053 is coaxially fixed on the cam 051, and the output shaft of the motor is coaxially fixed to the cam 051 shaft through a coupling 054, so that the motor drives the cam 051 to rotate. In this way, it is relatively convenient and low-cost to realize the transmission connection between the output end of the second driving member 052 and the cam 051. In some embodiments of the present application, the motor can be a servo motor or a stepper motor, etc.

[0060] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, a bearing seat 09 is fixed on the base 01, and the connecting shaft 053 is rotatably connected to the bearing seat 09 through a bearing 10. In this way, it is beneficial to improve the stability of the installation of the cam 051.

[0061] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the pressing device further includes a support seat 11 and a placement table 12. Along the vertical direction, the pressure sensor 08 is supported between the support seat 11 and the placement table 12, and the placement table 12 is used to place target structures such as products and parts. In this way, the pressure exerted by the pressing member 03 on the target structure can act on the pressure sensor 08 through the placement table 12, so that the pressure sensor 08 can detect the pressure between the pressing member 03 and the target structure. Moreover, the pressure sensor 08 is supported between the support seat 11 and the placement table 12, and can also be protected by the placement table 12 and the support seat 11 and is not easily damaged.

[0062] Please refer to Figure 1 、 Figure 2 and Figure 5 , in some embodiments of the present application, the pressing device further includes a connecting shaft 053, a clamping block 06 and a third driving member 07, Figure 5 In, the axial direction of the connecting shaft 053 is perpendicular to the paper surface. The clamping block 06 is provided with a through hole 061, and a part of the side wall of the through hole 061 protrudes and extends to form a clamping arm 0611. The clamping block 06 is fixed on the base 01; the connecting shaft 053 is coaxially fixed on the cam 051 and passes through the inside of the clamping arm 0611; the third driving member 07 is connected to the clamping arm 0611, and the third driving member 07 drives the clamping arm 0611 to clamp and fix the connecting shaft 053 on the inner surface of the through hole 061. In such a structural form, the connecting shaft 053 is clamped and fixed by the through hole 061 to limit the rotation of the cam 051 relative to the base 01, which can reduce the load of the second driving member 052, can stably hold the mounting member 02 in the target position, and enable the pressing member 03 to stably apply a target pressure to the target structure, which is beneficial to improving the adaptability of the pressing device.

[0063] Please refer to Figure 1 、 Figure 2 andFigure 5 In the embodiments of the present application, the connecting shaft 053 is coaxially fixed to the cam 051, that is, the axis of the connecting shaft 053 is the same as the axis of the cam 051 rotating relative to the base 01, and the connecting shaft 053 is fixed to the cam 051.

[0064] Please refer to Figure 1 , Figure 2 and Figure 5 , in some embodiments of the present application, the inner surface of the through hole 061 can extend circumferentially along the connecting shaft 053. In this way, when the inner surface of the through hole 061 clamps the connecting shaft 053, the contact area between the inner surface of the through hole 061 and the connecting shaft 053 is relatively large, which is beneficial to improving the clamping stability.

[0065] Please refer to Figure 1 , Figure 2 and Figure 5 , in some embodiments of the present application, the third driving member 07 can be a cylinder, an oil cylinder or a linear motor, etc. In this way, the structure is relatively simple, the implementation cost is relatively low, and a relatively reliable acting force can be applied to the clamping arm 06. Exemplarily, in some embodiments of the present application, the third driving member 07 is a cylinder, and the extending direction of the piston rod of the third driving member 07 can be the arrangement direction of the clamping arm 0611 and the connecting shaft 053. The piston cylinder of the third driving member 07 is fixed to the base 01, and the piston rod is connected to the clamping arm 0611. During the movement of the piston rod of the third driving member 07 relative to the piston cylinder, the connecting shaft 053 and the clamping arm 0611 can approach and separate from each other. It can be that when the piston rod of the third driving member 07 is in the extended state, the inner surface of the through hole 061 clamps and fixes the connecting shaft 053; or it can be that when the piston rod of the third driving member 07 is in the retracted state, the inner surface of the through hole 061 clamps and fixes the connecting shaft 053. The embodiments of the present application do not make any limitations in this regard. Exemplarily, referring to Figure 5 , the extending direction of the piston rod of the third driving member 07 is the up-and-down direction. The piston rod of the third driving member 07 moves downward relative to the cylinder body, pulling the clamping arm 0611 to move downward. The lower side surface of the clamping arm 0611 will abut against the upper side surface of the connecting shaft 053, causing the clamping arm 0611 to drive the connecting shaft 053 to move downward, so that the lower side surface of the clamping arm 0611 abuts against the inner surface of the through hole 061. In this way, both the upper side surface and the lower side surface of the connecting shaft 053 abut against the inner surface of the through hole 061, that is, the inner surface of the through hole 061 clamps and fixes the connecting shaft 053.
