In addition, in the description of the present application, it should be noted that the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0063] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0064] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 , define the X-axis direction as the first direction and the Z-axis direction as the second direction.

[0065] See also Figure 1The present application embodiment provides a pressing mechanism 100 for pressing a plurality of workpieces 2000 together. The workpieces 2000 may be sheet-shaped or ring-shaped structures, such as lenses, steel sheets, etc. The pressing mechanism 100 includes a supporting assembly 10, a pressing assembly 20, and a driving assembly 30.

[0066] Specifically, see Figure 1 and Figure 2 The support assembly 10 includes a base 11 and a sliding seat 12. The base 11 is provided with a slide rail 111 extending in the X-axis direction, and the sliding seat 12 is slidably connected to the slide rail 111. The base 11 can be a plate-like structure to improve the support stability. When the base 11 is connected to the external structure, it can be fixedly connected by bolts (not shown) and other parts. The slide rail 111 can be a columnar structure erected above the base 11. The sliding seat 12 is provided with a hole corresponding to the slide rail 111, so that the sliding seat 12 can be sleeved on the slide rail 111 to achieve sliding in the X-axis direction. Of course, the slide rail 111 can also be other structures, as long as the sliding seat 12 can move along the slide rail 111 in the X-axis direction and can limit the position of the sliding seat 12 in the Z-axis direction, which is not limited here. It can be understood that in order to improve the stability of the sliding seat 12 during movement, two slide rails 111 can be provided, and the two slide rails 111 are arranged parallel to each other.

[0067] See also Figure 2 , Figure 3 and Figure 4 The pressing assembly 20 includes a pressing member 21, a connecting member 22 and a first elastic member 23. The pressing member 21 includes a main body 211 and a pressing portion 212 connected to each other. The main body 211 is movably arranged on the sliding seat 12. A receiving groove 2111 and a through hole 2112 spaced apart from the receiving groove 2111 are provided on one side of the main body 211 close to the sliding seat 12. The through hole 2112 extends along the Z-axis direction. The pressing portion 212 extends out of the main body 211 along the X-axis direction. The connecting member 22 is inserted into the through hole 2112 and fixedly connected to the sliding seat 12. One end of the connecting member 22 away from the sliding seat 12 extends out of the through hole 2112 and is provided with a limiting portion 221. The first elastic member 23 is arranged in the through hole 2112 and its two ends are respectively abutted against the sliding seat 12 and the limiting portion 221. The first elastic member 23 is used to push the main body 211 to move in the opposite direction of the Z-axis direction, so that the pressing portion 212 moves in the opposite direction of the Z-axis direction and thereby presses the workpiece 2000.

[0068] The connecting member 22 may be a columnar structure, and the limiting portion 221 may be a sheet structure. The connecting member 22 is fixedly connected to the sliding seat 12, so the connecting member 22 only moves along the X-axis direction with the sliding seat 12, and does not move in the Z-axis direction. The first elastic member 23 may be a spring, etc. In order to improve the stability of the first elastic member 23, the first elastic member 23 may be arranged by sleeved on the connecting member 22. The first elastic member 23 is arranged in the through hole 2112, and the two ends are respectively abutted against the main body 211 and the limiting portion 221. Therefore, when the external force drives the pressing member 21 to move along the Z-axis direction, the main body 211 squeezes the first elastic member 23, and the second elastic member 28 can limit the moving distance of the main body 211 in the Z-axis direction. When the external force is removed, the first elastic member 23 can drive the main body 211 to move in the opposite direction along the Z-axis, thereby driving the pressing portion 212 to move in the opposite direction along the Z-axis, thereby causing the pressing portion 212 to press the workpiece 2000 .

[0069] The driving assembly 30 includes a driving handle 31 and an eccentric wheel 32. The driving handle 31 is rotatably connected to the main body 211 and inserted into the receiving groove 2111. The eccentric wheel 32 is disposed in the receiving groove 2111 and connected to the driving handle 31. The driving handle 31 is used to drive the eccentric wheel 32 to rotate to push the main body 211 to move along the Z-axis direction, so that the pressing part 212 moves along the Z-axis direction. The driving handle 31 may include a connected connecting rod 311 and a handle 312. The connecting rod 311 is rotatably connected to the main body 211 and inserted into the receiving groove 2111. The eccentric wheel 32 is connected to the connecting rod 311. The handle 312 is connected to an end of the connecting rod 311 away from the eccentric wheel 32 and is disposed outside the sliding seat 12. By rotating the handle 312, the connecting rod 311 and the eccentric wheel 32 can be driven to rotate, so that the eccentric wheel 32 is pressed against the sliding seat 12, and then the main body 211 and the pressing part 212 are driven to move along the Z-axis direction, and the pressing part 212 can avoid the workpiece 2000 to be pressed. When the sliding seat 12 drives the pressing assembly 20 to move along the X-axis direction along the slide rail 111 until the pressing part 212 corresponds to the workpiece 2000 in the Z-axis direction, the handle 312 is rotated to make the protruding position of the eccentric wheel 32 move away from the sliding seat 12, and the first elastic member 23 pushes the main body 211 and the pressing part 212 to move in the opposite direction of the Z-axis direction, so that the workpiece 2000 can be pressed.

[0070] The pressing mechanism 100 provided by the present application can be fixedly connected to an external structure through the base 11 in the support assembly 10 to fix the pressing mechanism 100. The pressing mechanism 100 is fixed near the position where the workpiece 2000 is placed, so that the pressing part 212 in the pressing assembly 20 corresponds to the workpiece 2000. The sliding seat 12 can move along the slide rail 111, thereby driving the pressing assembly 20 to move in the X-axis direction. When the workpiece 2000 is placed, the sliding seat 12 drives the pressing assembly 20 to move in the opposite direction of the X-axis direction to move away from the position where the workpiece 2000 is placed, so as to facilitate the placement of the workpiece 2000. During the pressing process, the driving handle 31 drives the eccentric wheel 32 to rotate, so as to lift the pressing part 21 along the Z-axis direction, and then the sliding seat 12 moves the pressing part 21 to a position opposite to the workpiece 2000 along the X-axis direction, and then the driving handle 31 is rotated, and the first elastic member 23 pushes the pressing part 21 in the opposite direction of the Z-axis direction, so that the pressing part 212 presses the workpiece 2000. During the pressing process, the connecting member 22 can limit the movement trajectory of the pressing part 21, so as to improve the stability of the pressed workpiece 2000, improve the pressing accuracy, and enhance the pressing effect.

[0071] In some embodiments, see Figure 1 and Figure 2 The pressing assembly 20 also includes a pressing head 24, which is detachably connected to the side of the pressing part 212 facing the sliding seat 12, and the pressing head 24 is used to abut the workpiece 2000 to press the workpiece 2000. The pressing head 24 can be a cylindrical structure, a rectangular structure, etc., and the specific structure and size can be set according to the structure of the workpiece 2000. The side of the pressing head 24 that contacts the workpiece 2000 can also be provided with a contoured portion, which is not limited here. The material of the pressing head 24 can be a flexible material such as urethane foam to avoid damage to the surface of the workpiece 2000 when pressing the workpiece 2000. The pressing head 24 is detachably connected to the pressing part 212, so that different pressing heads 24 can be replaced according to different workpieces 2000 to improve applicability. After wear caused by repeated use, the pressing head 24 can be replaced to reduce maintenance costs.

[0072] In some embodiments, see Figure 1 and Figure 2The pressing assembly 20 further includes a connecting pin 241 and a limiting plate 25. The connecting pin 241 is connected to the pressing part 212 and connected to the pressing head 24. The limiting plate 25 is connected to the side of the pressing part 21 away from the sliding seat 12 and covers the connecting pin 241, and is used to limit the connecting pin 241. The connecting pin 241 can be a bolt, etc. The connecting pin 241 is inserted into the pressing part 212 from the side of the pressing part 212 away from the sliding seat 12 and passes through the pressing part 212. The pressing head 24 is connected to the connecting pin 241 extending out of the pressing part 212. The connecting pin 241 may not pass through the pressing head 24, so that the connecting pin 241 can be prevented from contacting the workpiece 2000 and causing damage to the workpiece 2000 during pressing. The limiting plate 25 is connected to the pressing part 21 and covers the connecting pin 241, so that the connecting pin 241 can be limited in the Z-axis direction, and the connecting pin 241 can be prevented from moving in the Z-axis direction after multiple pressings, causing the pressing head 24 to be unstable.

[0073] In some embodiments, see Figure 4 , Figure 5 and Figure 6 The base 11 includes a head end 112 and a tail end 113 arranged along the X-axis direction, and the tail end 113 is provided with a first positioning hole 1131. The pressing assembly 20 also includes a first positioning pin 26, which is arranged on a side of the body 211 close to the pressing part 212. When the sliding seat 12 drives the pressing part 21 to move to the tail end 113, the first positioning pin 26 is inserted into the first positioning hole 1131 to position the pressing part 21. The first positioning pin 26 can be a columnar structure, arranged along the Z-axis direction, and the first positioning hole 1131 is adapted to the structure of the first positioning pin 26 and is also arranged along the Z-axis direction. When pressing the workpiece 2000, the driving handle 31 drives the eccentric wheel 32 to push the pressing part 21 to move along the Z-axis direction, and then the sliding seat 12 drives the pressing part 21 to move along the X-axis direction to the end 113 of the base 11, and the driving handle 31 drives the eccentric wheel 32 to rotate, so that the first elastic member 23 drives the pressing part 21 to move in the opposite direction of the Z-axis direction. At this time, the first positioning pin 26 is inserted into the first positioning hole 1131 to precisely position the pressing part 21, thereby improving the accuracy of the pressing head 24 when pressing the workpiece 2000. In order to further improve the positioning accuracy, two first positioning holes 1131 can be provided on the base 11, and two first positioning pins 26 are correspondingly provided.

[0074] In some embodiments, see Figure 1, the head end 112 is provided with a second positioning hole 1121. The pressing assembly 20 further includes a second positioning pin 27, which is provided on a side of the body 211 away from the pressing part 212. When the sliding seat 12 drives the pressing part 21 to move to the head end 112, the second positioning pin 27 is inserted into the second positioning hole 1121 to limit the pressing part 21. It can be understood that when placing the workpiece 2000, the sliding seat 12 and the pressing part 21 need to be moved in the opposite direction of the X-axis direction first, so that the pressing part 212 avoids the position where the workpiece 2000 is placed, so as to facilitate material placement. By providing the second positioning hole 1121 and the second positioning pin 27, when the sliding seat 12 drives the pressing piece 21 to move in the opposite direction of the X-axis direction to avoid the position where the workpiece 2000 is placed, the second positioning pin 27 is inserted into the second positioning hole 1121, and the sliding seat 12 and the pressing piece 21 can be limited in the X-axis direction to avoid the sliding seat 12 moving when the workpiece 2000 is placed, which affects the discharge of the material. In order to further improve the stability of the limit, two second positioning holes 1121 can be provided on the base 11, and two second positioning pins 27 are correspondingly provided.

[0075] In some embodiments, see Figure 1 , Figure 2 and Figure 6 The pressing assembly 20 further includes a plurality of second elastic members 28 corresponding to the first positioning pin 26 and the second positioning pin 27, one end of the second elastic member 28 is connected to the main body 211, and the other end of the second elastic member 28 is connected to the corresponding first positioning pin 26 or the second positioning pin 27, and the second elastic member 28 is used to elastically support the first positioning pin 26 or the second positioning pin 27. The second elastic member 28 can be a spring or the like. It can be understood that the first positioning pin 26 and the second positioning pin 27 are both connected to the main body 211 through the corresponding second elastic member 28, and the first positioning pin 26 and the second positioning pin 27 can float in the Z-axis direction, so as to avoid the first positioning pin 26 and the second positioning pin 27 from being in rigid contact with the base 11 when the pressing member 21 is positioned or limited by the first positioning pin 26 or the second positioning pin 27, thereby preventing the first positioning pin 26 and the second positioning pin 27 from being in rigid contact with the base 11, thereby causing structural damage.

[0076] In one embodiment, the first positioning pin 26 and the second positioning pin 27 can be set to a hemispherical structure at one end facing the base 11, and the first positioning hole 1131 and the second positioning hole 1121 can be set to have a trumpet-shaped opening at one end facing the pressing part 21, so as to facilitate the first positioning pin 26 to be inserted into the first positioning hole 1131 and the second positioning pin 27 to be inserted into the second positioning hole 1121.

[0077] In some embodiments, see Figure 2The pressing assembly 20 further includes a sleeve 29, which is disposed in the through hole 2112 and fixedly connected to the main body 211. The sleeve 29 is slidably sleeved on the connecting member 22, and one end of the sleeve 29 disposed toward the limiting portion 221 abuts against the first elastic member 23 to support the first elastic member 23. When the pressing member 21 moves in the Z-axis direction, the sleeve 29 moves in the Z-axis direction with the pressing member 21. The sleeve 29 is sleeved on the connecting member 22, which can improve the stability of the pressing member 21 in the Z-axis direction.

[0078] In some embodiments, see Figure 4 and Figure 5 The support assembly 10 further includes a stopper 13, which is connected to a side of the sliding seat 12 close to the driving handle 31, and is used to abut against the driving handle 31 to limit the driving handle 31. The stopper 13 may be in a strip or block shape, and when the driving handle 31 rotates and moves to the position of the stopper 13, the stopper 13 may stop the driving handle 31 from continuing to rotate, so as to prevent the driving member from driving the eccentric wheel 32 to rotate and push the pressing member 21 away from the sliding seat 12 along the Z-axis direction, and the eccentric wheel 32 continues to move, causing the protruding portion of the eccentric wheel 32 to move away from the sliding seat 12, causing the pressing member 21 to move in the opposite direction of the Z-axis direction.

[0079] In some embodiments, see Figure 1 A plurality of limiting protrusions 121 are provided on the side of the sliding seat 12 away from the base 11. The plurality of limiting protrusions 121 extend along the Z-axis direction and abut against the main body 211, and are used to limit the position of the main body 211. By providing a plurality of limiting protrusions 121, when the main body 211 of the pressing member 21 moves in the Z-axis direction, the position of the main body 211 in a plane perpendicular to the Z-axis direction can be limited.

[0080] The working process of the pressing mechanism 100 provided in the embodiment of the present application is roughly as follows:

[0081] First, fix the base 11, then rotate the driving handle 31, the driving handle 31 drives the eccentric wheel 32 to move, and then push the pressing member 21 along the Z-axis direction until the driving handle 31 abuts against the stopper 13. Then pull the sliding seat 12 to move in the opposite direction of the X-axis direction, so that the second positioning pin 27 corresponds to the second positioning hole 1121. Please refer to Figure 1 , the driving handle 31 is rotated in the reverse direction, the first elastic member 23 pushes the pressing member 21 to move in the opposite direction along the Z-axis direction, and the second positioning pin 27 is inserted into the second positioning hole 1121 to limit the sliding seat 12 and the pressing member 21.

[0082] Then, the workpiece 2000 is placed near the end 113 of the base 11. After the multiple workpieces 2000 are stacked in sequence, refer to Figure 3 and Figure 4, the driving handle 31 is rotated, the eccentric wheel 32 lifts the pressing member 21, and pushes the pressing member 21 along the Z-axis direction until the driving handle 31 abuts against the stopper 13. Figure 5 Then, the sliding seat 12 is pulled to move along the X-axis direction, so that the pressing part 212 and the pressing head 24 correspond to the plurality of workpieces 2000. At this time, the first positioning pin 26 corresponds to the position of the first positioning hole 1131. Please refer to Figure 6 , the driving handle 31 is rotated in the reverse direction, the first elastic member 23 pushes the pressing member 21 to move in the reverse direction along the Z-axis direction, and the first positioning pin 26 is inserted into the first positioning hole 1131 to position the pressing member 21, thereby positioning the pressing head 24. During the movement in the reverse direction along the Z-axis direction, the pressing head 24 presses the multiple workpieces 2000 together.
