[0001] The present application relates to the technical field of automation equipment, and in particular to a down-pressing protection device, a down-pressing system and a down-pressing method. Background Art

[0002] A pressing device with a pressing function may automatically press down in an uncontrolled state when it is in maintenance or shutdown state, thereby causing the risk of crushing injuries to the operator. Summary of the invention

[0003] In view of the defects of the prior art, the purpose of the present application is to provide a pressing protection device, a pressing system and a pressing method, which can effectively solve the problem that the pressing device automatically presses down in an uncontrolled state: In a first aspect, the present application provides a downward pressure protection device for protecting the downward pressure action of the movable end of the downward pressure device along a first direction, including: A driving mechanism, the driving mechanism comprising a first driving member, A limiting mechanism, the limiting mechanism is connected to the first driving member and can move along the second direction under the action of the first driving member, the limiting mechanism has a first position and a second position along the second direction, the limiting mechanism is provided with a limiting member, the limiting member is configured to be able to separate from the movable end when the limiting mechanism is in the first position, the limiting member is also configured to be able to abut against the movable end when the limiting mechanism is in the second position, and is used to limit the downward movement of the movable end, wherein the first direction intersects with the second direction.

[0004] According to the downward pressure protection device of the present application, when the downward pressure device is operating normally, the first driving member can be used to drive the limiting mechanism to run to the first position, so that the limiting member is separated from the movable end, so that the downward pressure device can operate normally and complete the downward pressure action; when the downward pressure device is in a maintenance state or a shutdown state, the first driving member can be used to drive the limiting mechanism to run to the second position, so that the limiting member is abutted against the movable end, and is used to limit the downward pressure action of the movable end along the first direction, thereby reducing the phenomenon of automatic downward pressure of the downward pressure device in an uncontrolled state and reducing safety hazards.

[0005] In some embodiments of the present application, the limiting mechanism also includes a buffer assembly, the limiting member is connected to the buffer assembly, the buffer assembly includes a buffer member, the limiting member can move along a first direction, and the buffer member is configured to be able to deform during the movement of the limiting member along the first direction.

[0006] When the limit member abuts against the movable end and is used to limit the downward movement of the movable end along the first direction, the limit member can move together with the movable end along the first direction under the action of the movable end, and the buffer member can be deformed during the movement of the limit member along the first direction, thereby slowing down the movement speed of the limit member and the movable end along the first direction, thereby reducing the impact caused by the downward movement process.

[0007] In some embodiments of the present application, the buffer member is an elastic buffer member and is configured to be able to undergo elastic deformation during the movement of the limiting member along the first direction.

[0008] By setting the buffer as an elastic buffer and enabling it to undergo elastic deformation along the first direction, the impact caused by the downward pressing process can be reduced. At the same time, when the limiting member is separated from the movable end, the buffer can be restored to its original state through its own elastic deformation, thereby driving the limiting member to return to its original position so as to limit the downward pressing action of the movable end again.

[0009] In some embodiments of the present application, the limiting mechanism also includes a mounting seat assembly, which is connected to the first driving member, and the mounting seat assembly is configured to be able to reciprocate along the second direction under the action of the first driving member, and the buffer assembly is arranged on the mounting seat assembly in a manner that can move along the first direction.

[0010] The limiting mechanism can be connected to the first driving member through the mounting seat assembly, so that it can reciprocate along the second direction under the action of the first driving member to switch the limiting mechanism between the first position and the second position member. At the same time, the limiting member is connected to the mounting seat assembly through the buffer assembly, so that the limiting member can abut or separate from the movable end during the position switching process of the limiting mechanism.

[0011] In some embodiments of the present application, the limiting member and the buffer member are respectively arranged on both sides of the mounting seat assembly along the first direction.

[0012] By arranging the limiter and the buffer on both sides of the mounting seat assembly along the first direction respectively, the overall structural arrangement of the limiter mechanism is facilitated, and the problem of one side of the mounting seat assembly being too large due to the limiter and the buffer being arranged on one side of the mounting seat assembly, which affects the installation, is reduced.

[0013] In some embodiments of the present application, the buffer assembly also includes a support rod and a fixing member. The support rod is inserted into the mounting seat assembly along a first direction and can move along the first direction. A limit member is provided at one axial end of the support rod, and a fixing member is provided at the other axial end of the support rod. The buffer member is sleeved on the outside of the support rod, and the buffer member is clamped between the fixing member and the mounting seat assembly along the first direction.

[0014] By clamping the buffer member between the fixing member and the mounting seat assembly along the first direction, when the limiting member abuts against the movable end and is pressed downward with the movable end, the buffer member can be compressed between the fixing member and the mounting seat assembly, thereby providing a buffering force. When the limiting member is separated from the movable end, the buffer member can return to its original state through its own elastic deformation, thereby driving the limiting member to return to its original position.

[0015] In some embodiments of the present application, the mounting seat assembly includes a seat body and a sleeve, the seat body is connected to the first driving member, the sleeve is passed through the seat body, the sleeve has a first mounting hole passing through it along a first direction, the support rod is passed through the first mounting hole, and the buffer member is clamped between the fixing member and the sleeve along the first direction.

[0016] The support rod can be inserted into the first mounting hole of the sleeve along the first direction, so that the buffer assembly is connected to the mounting seat assembly. When the support rod reciprocates along the first direction for many times, it is easy to cause the contact surface between the mounting seat assembly and the support rod to wear. Since the support rod is inserted into the sleeve, only the inner wall surface of the sleeve is worn, and the inner wall surface of the seat body will not be worn. Therefore, only the sleeve needs to be replaced without replacing the seat body.

[0017] In some embodiments of the present application, at least one end of the sleeve along the first direction protrudes from the seat body, and the mounting seat assembly is further provided with a positioning member, which is arranged on the seat body and is used to limit the movement of the sleeve along the first direction.

[0018] By providing a positioning member and limiting the movement of the sleeve in the first direction through the positioning member, the phenomenon of failure of the buffer assembly and the limit member due to the sleeve moving together with the support rod and separating from the seat during the movement of the support rod can be reduced.

[0019] In some embodiments of the present application, the limiting member includes a sleeve portion and a limiting portion, the sleeve portion is sleeved on one end of the support rod along its own axial direction away from the fixing member, the limiting portion protrudes from the outer peripheral surface of the sleeve portion, and the limiting portion is configured to be able to abut against the movable end when the limiting mechanism is in the second position.

[0020] By sleeve-mounted the sleeve portion on the end portion of the support rod, the positioning connection between the limit member and the support rod is achieved. At the same time, the limit member is protruded from the outer circumferential surface of the sleeve portion so that the movable end can be hooked on the side of the limit member facing the sleeve portion, thereby limiting the movement of the movable end along the first direction through the limit member.

[0021] In some embodiments of the present application, the downward pressure protection device further includes a supporting mechanism, the first driving member is connected to the supporting mechanism, and the supporting mechanism is configured to be connectable to the downward pressure device.

[0022] The first driving member can be connected to the supporting mechanism, so that the entire pressing protection device is connected to the pressing device through the supporting mechanism, thereby facilitating the fixing of the pressing protection device and limiting the pressing action of the movable end.

[0023] In some embodiments of the present application, the pressure protection device further includes a detection mechanism, which is configured to be connectable to the pressure device and used to detect that the limiting mechanism is in the first position and / or the limiting mechanism is in the second position.

[0024] The detection mechanism detects that the limit mechanism is in the first position, thereby determining that the limit member is separated from the movable end so that the pressing action can be performed. The detection mechanism detects that the limit mechanism is in the second position, thereby determining that the limit member is in contact with the movable end and is used to limit the pressing action of the movable end so that the pressing device can be repaired and operated.

[0025] In some embodiments of the present application, the detection mechanism includes a first detection member and a second detection member, the first detection member and the second detection member are respectively configured to be connected to the pressing device, the first detection member and the second detection member are spaced apart along the second direction, the first detection member is configured to detect that the limiting mechanism is in the first position, and the second detection member is configured to detect that the limiting mechanism is in the second position.

[0026] By providing the first detection member and the second detection member, it is possible to accurately detect whether the limiting mechanism is in the first position or the second position, thereby determining whether to operate or inspect the pressing device.

[0027] On the second aspect, the present application also proposes a downward pressing system, including any of the above-mentioned downward pressing protection devices, the downward pressing system also includes a downward pressing device, the downward pressing device includes a second driving member and a movable end connected to the second driving member, the movable end is configured to be able to move along a first direction under the action of the second driving member, the limiting member is configured to be able to separate from the movable end when the limiting mechanism is in the first position, and the limiting member is also configured to be able to abut against the movable end when the limiting mechanism is in the second position, and is used to limit the downward pressing action of the movable end.

[0028] According to the pressing system of the present application, when the pressing device is operating normally, the first driving member can be used to drive the limiting mechanism to run to the first position, thereby separating the limiting member from the movable end, so that the pressing device can operate normally and complete the pressing action; when the pressing device is in a maintenance state or a shutdown state, the first driving member can be used to drive the limiting mechanism to run to the second position, thereby making the limiting member abut against the movable end, and being used to limit the pressing action of the movable end along the first direction, thereby reducing the phenomenon of the pressing device automatically pressing down in an uncontrolled state and reducing safety hazards.

[0029] In some embodiments of the present application, the pressing device further includes a fixed end, the second driving member is disposed at the fixed end, and the movable end is configured to be able to move relative to the fixed end along the first direction under the action of the second driving member.

[0030] The fixed end can be used to fix the second driving member, so that the movable end is driven by the second driving member to perform a downward pressing action along the first direction.

[0031] In a third aspect, the present application further proposes a pressing method, which is applied to any of the above pressing systems, comprising: According to the pressing device being in an abnormal state and the movable end not completing the pressing action, controlling the limit mechanism to move to the second position; Handling abnormal conditions; After the abnormal state is processed, the limiting mechanism is controlled to move to the first position, and the limiting member of the limiting mechanism is separated from the movable end of the pressing device.

[0032] According to the pressing method of the present application, by controlling the limit mechanism to switch between the first position and the second position, the limit member is controlled to separate or abut against the movable end, thereby determining the operation or maintenance of the pressing device, reducing the phenomenon of the pressing device automatically pressing down in an uncontrolled state, and reducing safety hazards.

[0034] When the pressing device is in any of the above abnormal states, there is a risk of the pressing device automatically pressing down. By controlling the limit mechanism to move to the second position and making the limit member abut against the movable end, the phenomenon of the pressing device automatically pressing down in an uncontrolled state can be reduced, thereby reducing safety hazards.

[0047] A pressing device with a pressing function may automatically press down in an uncontrolled state when it is in maintenance or shutdown state, thereby causing the risk of crushing injuries to the operator.

[0048] In order to solve the problem of the pressing device automatically pressing down in an uncontrolled state, the present application proposes a pressing protection device, a pressing system and a pressing method, which can reduce the phenomenon of the pressing device automatically pressing down in an uncontrolled state and reduce safety hazards.

[0049] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the downward pressure protection device 100 is used to protect the downward pressure action of the movable end 202 of the downward pressure device 200 along the first direction X. The downward pressure protection device 100 includes a driving mechanism 10 and a limiting mechanism 20. The driving mechanism 10 includes a first driving member 11. The limiting mechanism 20 is connected to the first driving member 11 and can move along the second direction Y under the action of the first driving member 11. The limiting mechanism 20 has a first position and a second position along the second direction Y. The limiting mechanism 20 is provided with a limiting member 21. The limiting member 21 is configured to be able to separate from the movable end 202 when the limiting mechanism 20 is in the first position. The limiting member 21 is also configured to be able to abut against the movable end 202 when the limiting mechanism 20 is in the second position, and is used to limit the downward pressure action of the movable end 202.

[0050] Specifically, the pressing device 200 includes a second driving member 201 and a movable end 202, wherein the movable end 202 is connected to the output end of the second driving member 201, and can perform a pressing action along the first direction X under the drive of the second driving member 201, that is, move in a direction away from the second driving member 201, thereby stamping a plate-like structure or a structure of other shapes to achieve the purpose of rapid shaping. Optionally, the second driving member 201 can be a driving cylinder, and the movable end 202 includes a pressing head 2021, a movable plate 2022 and a connecting block 2023 connected in sequence, and the cylinder rod of the second driving member 201 is connected to the connecting block 2023, so that the pressing head 2021 is driven to perform a pressing action along the first direction X under the action of the second driving member 201. Optionally, the first direction X and the second direction Y are perpendicular to each other, the first direction X can be a vertical direction, and the second direction Y can be a horizontal direction. The pressing action is the downward movement of the pressing head 2021 along the vertical direction. In some other implementations of the present application, the pressing head 2021 may also be directly connected to the output end of the second driving member 201 .

[0051] The downward pressure protection device 100 includes a driving mechanism 10 and a limiting mechanism 20, wherein the driving mechanism 10 includes a first driving member 11, and the output end of the first driving member 11 is connected to the limiting mechanism 20, so that it can be used to drive the limiting mechanism 20 to reciprocate along the second direction Y. The limiting mechanism 20 has a first position and a second position during the movement along the second direction Y. When the limiting mechanism 20 is in the first position, the limiting member 21 of the limiting mechanism 20 is separated from the movable end 202, so that the downward pressure device 200 operates normally and completes the downward pressure action. When the limiting mechanism 20 is in the second position, the limiting member 21 abuts against the movable end 202 and is used to limit the downward pressure action of the movable end 202 along the first direction X, thereby reducing the phenomenon that the downward pressure device 200 automatically presses down in an uncontrolled state, thereby reducing safety hazards. Optionally, the first driving member 11 may be a driving cylinder, and the driving mechanism 10 further includes a connecting plate 12, through which the cylinder rod of the first driving member 11 may be connected to the limiting mechanism 20, thereby facilitating the driving connection between the first driving member 11 and the limiting mechanism 20. Optionally, when the limiting mechanism 20 is in the second position, the limiting member 21 may be brought into contact with a side surface of the movable plate 2022 that is away from the second driving member 201, thereby limiting the downward pressing action of the movable plate 2022.

[0052] According to the downward pressure protection device 100 of the present application, when the downward pressure device 200 operates normally, the first driving member 11 can be used to drive the limiting mechanism 20 to run to the first position, so that the limiting member 21 is separated from the movable end 202, so that the downward pressure device 200 operates normally and completes the downward pressure action; when the downward pressure device 200 is in a maintenance state or a shutdown state, the first driving member 11 can be used to drive the limiting mechanism 20 to run to the second position, so that the limiting member 21 is abutted against the movable end 202, and is used to limit the downward pressure action of the movable end 202 along the first direction X, thereby reducing the phenomenon of the downward pressure device 200 automatically pressing down in an uncontrolled state, thereby reducing safety hazards.

[0053] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the limiting mechanism 20 also includes a buffer assembly 22, the limiting member 21 is connected to the buffer assembly 22, the buffer assembly 22 includes a buffer member 221, the limiting member 21 can move along the first direction X, and the buffer member 221 is configured to be able to deform during the movement of the limiting member 21 along the first direction X.

[0054] Specifically, the buffer 221 has a certain deformation ability, so that when the limiter 21 moves along the first direction X, the movement speed of the limiter 21 is reduced due to the deformation of the buffer 221, thereby achieving the purpose of reducing the impact. Optionally, when the limiter 21 moves along the first direction X, the buffer 221 can be specifically selected to be compressed or stretched according to the setting mode.

[0055] When the limiting member 21 is in contact with the movable end 202 and is used to limit the downward pressing action of the movable end 202 along the first direction X, the limiting member 21 can move together with the movable end 202 along the first direction X under the action of the movable end 202, and the buffer member 221 can be deformed during the movement of the limiting member 21 along the first direction X, thereby slowing down the movement speed of the limiting member 21 and the movable end 202 along the first direction X, thereby reducing the impact caused by the downward pressing process.

[0056] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the buffer member 221 is an elastic buffer member and is configured to be able to undergo elastic deformation during the movement of the limiting member 21 along the first direction X.

[0057] Specifically, the buffer member 221 can be an elastic buffer member, such as a spring, so that it can undergo elastic deformation during the movement of the limit member 21 along the first direction X, and after the limit member 21 is separated from the movable end 202, it can recover to its original state through its own elastic deformation, thereby driving the limit member 21 to return to its original position, so as to limit the downward movement of the movable end 202 again.

[0058] Combination Figures 1 to 6As shown, in some embodiments of the present application, the limiting mechanism 20 also includes a mounting seat assembly 23, which is connected to the first driving member 11, and the mounting seat assembly 23 is configured to be able to reciprocate along the second direction Y under the action of the first driving member 11, and the buffer assembly 22 is arranged on the mounting seat assembly 23 in a manner that it can move along the first direction X.

[0059] Specifically, the mounting seat assembly 23 is used to mount the buffer assembly 22 and the limiting member 21 , so that the limiting member 21 reciprocates along the second direction Y under the action of the first driving member 11 and abuts against or separates from the movable end 202 .

[0060] The limiting mechanism 20 can be connected to the first driving member 11 through the mounting seat assembly 23, so that it can reciprocate along the second direction Y under the action of the first driving member 11, so that the limiting mechanism 20 can switch between the first position and the second position member. At the same time, the limiting member 21 is connected to the mounting seat assembly 23 through the buffer assembly 22, so that the limiting member 21 can abut or separate from the movable end 202 during the position switching process of the limiting mechanism 20.

[0061] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the limiting member 21 and the buffer member 221 are respectively arranged on both sides of the mounting seat assembly 23 along the first direction X.

[0062] Specifically, the limiter 21 and the buffer 221 are respectively disposed on opposite sides of the mounting seat assembly 23 along the first direction X. Optionally, the limiter 21 may be disposed below the mounting seat assembly 23 along the vertical direction, and the buffer 221 may be disposed above the mounting seat assembly 23 along the vertical direction.

[0063] By arranging the limit member 21 and the buffer member 221 on both sides of the mounting seat assembly 23 along the first direction X, the overall structural setting of the limit mechanism 20 is facilitated, and the size of one side of the mounting seat assembly 23 is reduced due to the limit member 21 and the buffer member 221 being arranged on one side of the mounting seat assembly 23, thereby affecting the installation.

[0064] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the buffer assembly 22 also includes a support rod 222 and a fixing member 223. The support rod 222 is inserted into the mounting seat assembly 23 along the first direction X and can move along the first direction X. A limit member 21 is provided at one axial end of the support rod 222, and a fixing member 223 is provided at the other axial end of the support rod 222. The buffer member 221 is sleeved on the outside of the support rod 222, and the buffer member 221 is clamped between the fixing member 223 and the mounting seat assembly 23 along the first direction X.

[0065] Specifically, the support rod 222 is a rod-shaped structure, and the axial direction of the support rod 222 can be arranged along the first direction X, and the support rod 222 is arranged in the mounting seat assembly 23 along the first direction X. A stopper 21 is provided on one side of the support rod 222 located at the mounting seat assembly 23, and a fixing member 223 is provided on the other side of the support rod 222 located at the mounting seat assembly 23, and the fixing member 223 is arranged protruding from the outer peripheral surface of the support rod 222. The buffer 221 can be a spring, sleeved on the outside of the support rod 222, and clamped between the fixing member 223 and the mounting seat assembly 23 along the first direction X, so that when the stopper 21 abuts against the movable end 202 and moves downward or has a tendency to move downward under the action of the downward pressure of the movable end 202, the buffer 221 can be squeezed and the impact force can be reduced by the buffer 221. Optionally, the fixing member 223 and the support rod 222 can be connected by a connecting bolt 24, and the connecting bolt 24 passes through the fixing member 223 and the support rod 222 in sequence along the first direction X.

[0066] By clamping the buffer member 221 between the fixing member 223 and the mounting seat assembly 23 along the first direction X, when the limiting member 21 abuts against the movable end 202 and is pressed downward with the movable end 202, the buffer member 221 can be compressed between the fixing member 223 and the mounting seat assembly 23, thereby providing a buffering force. When the limiting member 21 is separated from the movable end 202, the buffer member 221 can be restored to its original state through its own elastic deformation, thereby driving the limiting member 21 to return to its original position.

[0067] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the mounting seat assembly 23 includes a seat body 231 and a sleeve 232, the seat body 231 is connected to the first driving member 11, the sleeve 232 is passed through the seat body 231, the sleeve 232 is provided with a first mounting hole along the first direction X, the support rod 222 is passed through the first mounting hole, and the buffer member 221 is clamped between the fixing member 223 and the sleeve 232 along the first direction X.

[0068] Specifically, the seat body 231 is connected to the first driving member 11, and can reciprocate along the second direction Y under the action of the first driving member 11. The buffer assembly 22 is connected to the seat body 231 through the shaft sleeve 232, so that it reciprocates along the second direction Y with the seat body 231. Optionally, the seat body 231 can be provided with a through hole along the first direction X, and the shaft sleeve 232 can be inserted into the through hole of the seat body 231 and fixed. The shaft sleeve 232 is provided with a first mounting hole along its own axial direction, and the support rod 222 is inserted into the first mounting hole, so that the two ends of the support rod 222 along the first direction X are respectively arranged on both sides of the seat body 231. In some embodiments of the present application, the shaft sleeve 232 can also be arranged on the outside of the seat body 231 and connected to the outer surface of the seat body 231.

[0069] The support rod 222 can be inserted into the first mounting hole of the shaft sleeve 232 along the first direction X, so that the buffer assembly 22 is connected to the mounting seat assembly 23. When the support rod 222 reciprocates along the first direction X for many times, it is easy to cause the contact surface between the mounting seat assembly 23 and the support rod 222 to wear. Since the support rod 222 is inserted into the shaft sleeve 232, only the inner wall surface of the shaft sleeve 232 is worn, and the inner wall surface of the seat body 231 will not be worn. Therefore, only the shaft sleeve 232 needs to be replaced without replacing the seat body 231.

Optionally, the top of the sleeve 232 protrudes from the seat body 231, and a part of the structure is recessed to provide a plug-in groove 2321, and the positioning member 233 may be a sheet-like structure, and is fixed to the seat body 231 by bolt connection. The positioning member 233 of the partial sheet-like structure is plugged into the plug-in groove 2321, thereby positioning the sleeve 232 along the first direction X.

[0072] By providing a positioning member 233 and limiting the movement of the sleeve 232 along the first direction X through the positioning member 233, the phenomenon of failure of the buffer assembly 22 and the limit member 21 caused by the sleeve 232 moving together with the support rod 222 and separating from the seat body 231 during the movement of the support rod 222 can be reduced.

Optionally, the movable end 202 includes a movable plate 2022, and a first notch 20221 is provided on one side of the movable plate 2022 along the second direction Y.

Optionally, the limiting member 21 can be connected to the support rod 222 via a connecting bolt 24, and the connecting bolt 24 can pass through the limiting portion 212 and the support rod 222 in sequence along the first direction X.

[0075] By sleeve-mounted the sleeve portion 211 on the end of the support rod 222, the positioning connection between the limit member 21 and the support rod 222 is achieved. At the same time, the limit member 212 is protruded from the outer peripheral surface of the sleeve portion 211 so that the movable end 202 can be hooked on the side of the limit member 212 facing the sleeve portion 211, thereby limiting the movement of the movable end 202 along the first direction X through the limit member 21.

[0085] Specifically, since the limiting mechanism 20 has a first position and a second position along the second direction Y, and at the same time, the limiting mechanism 20 may also have an intermediate position between the first position and the second position, in order to accurately detect whether the limiting mechanism 20 is in the first position or the second position, the detection mechanism 40 in the present application includes a first detection member 41 and a second detection member 42, and the first detection member 41 and the second detection member 42 are arranged at intervals along the second direction Y.

[0088] Combination Figures 1 to 6 As shown, in the second aspect, the present application further proposes a downward pressing system 1000, the downward pressing system 1000 includes the downward pressing protection device 100 in any of the above-mentioned embodiments, the downward pressing system 1000 also includes a downward pressing device 200, the downward pressing device 200 includes a second driving member 201 and a movable end 202 connected to the second driving member 201, the movable end 202 is configured to be able to move along the first direction X under the action of the second driving member 201, the limiting member 21 is configured to be able to separate from the movable end 202 when the limiting mechanism 20 is in the first position, and the limiting member 21 is also configured to be able to abut against the movable end 202 when the limiting mechanism 20 is in the second position, and is used to limit the downward pressing action of the movable end 202 along the first direction X.

The cylinder rod of the second driving member 201 is connected to the connecting block 2023, so that the pressing head 2021 is driven to perform a downward action along the first direction X under the action of the second driving member 201.

[0090] According to the pressing system 1000 of the present application, when the pressing device 200 is operating normally, the limiting mechanism 20 can be driven by the first driving member 11 to run to the first position, so that the limiting member 21 is separated from the movable end 202, so that the pressing device 200 can operate normally and complete the pressing action; when the pressing device 200 is in a maintenance state or a shutdown state, the limiting mechanism 20 can be driven by the first driving member 11 to run to the second position, so that the limiting member 21 is abutted against the movable end 202, and is used to limit the pressing action of the movable end 202 along the first direction X, thereby reducing the phenomenon of the pressing device 200 automatically pressing down in an uncontrolled state, thereby reducing safety hazards.

[0091] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the pressing device 200 further includes a fixed end 203 , the second driving member 201 is disposed at the fixed end 203 , and the movable end 202 is configured to be able to move relative to the fixed end 203 along the first direction X under the action of the second driving member 201 .

[0092] Specifically, the fixed end 203 includes a fixed plate 2031, and the fixed plate 2031 and the movable plate 2022 can be arranged at intervals along the first direction X. The second driving member 201 is arranged on the fixed plate 2031, and the movable end 202 can move relative to the fixed plate 2031 along the first direction X under the action of the second driving member 201, so that the downward pressing is completed when the movable end 202 moves in a direction away from the fixed plate 2031.

[0093] Combination Figures 1 to 7 As shown, in a third aspect, the present application further proposes a pressing method, which is applied to the pressing system 1000 of any of the above embodiments, and includes the following steps: According to the pressing device 200 being in an abnormal state and the movable end 202 not completing the pressing action, the limiting mechanism 20 is controlled to move to the second position; Handling abnormal conditions; After the abnormal state is processed, the limiting mechanism 20 is controlled to move to the first position, and the limiting member 21 of the limiting mechanism 20 is separated from the movable end 202 of the pressing device 200 .

[0094] Specifically, before the pressing device 200 is started, the limiting mechanism 20 is in the first position, and the limiting member 21 is separated from the movable end 202, so that the movable end 202 can perform a pressing action along the first direction X. When it is necessary to perform a pressing action according to the pressing system 1000, the pressing device 200 is started and the pressing device 200 is controlled to operate normally. If the pressing device 200 is in no abnormal state during operation, the pressing action is performed normally. If the pressing device 200 is in an abnormal state during operation, and the movable end 202 has not completed the pressing action, if the pressing device 200 is repaired at this time, the pressing device 200 may continue the pressing action in an uncontrolled state, thereby causing a safety accident. Therefore, when the pressing device 200 is in an abnormal state and the movable end 202 has not completed the pressing action, it is necessary to control the limiting mechanism 20 to move to the second position, and make the limiting member 21 abut against the movable end 202. Since the limiter 21 can limit the pressing action of the movable end 202, the abnormal state can be handled at this time, and the safety hazard caused by the pressing device 200 continuing to press in an uncontrolled state can be reduced. After the abnormal state is handled, the limiter 20 is controlled to move to the first position, and the limiter 21 is separated from the movable end 202. At this time, the movable end 202 can continue to move along the first direction X, so as to continue to complete the pressing action or return the movable end 202 to the initial position for the next pressing action. Among them, the detection component of the pressing device 200 itself can detect whether the movable end 202 moves to the specified position along the first direction X, so as to determine whether the movable end 202 completes the pressing action. Optionally, the pressing device 200 and the pressing protection device 100 can be controlled to operate through the same control system, so as to automatically control the operating state of the pressing protection device 100 according to the operating state of the pressing device 200. Alternatively, the pressing device 200 and the pressing protection device 100 may be controlled and operated by different control systems respectively, and the operator may adjust and control the operating state of the pressing protection device 100 at any time according to the operating state of the pressing device 200 .

[0095] According to the pressing method of the present application, by controlling the limit mechanism 20 to switch between the first position and the second position, the limit member 21 is controlled to separate or abut against the movable end 202, thereby determining the operation or maintenance of the pressing device 200, reducing the phenomenon of the pressing device 200 automatically pressing down in an uncontrolled state, and reducing safety hazards.

[0096] Combination Figures 1 to 7 As shown, in some embodiments of the present application, the abnormal state includes at least one of the pressing device 200 being in a power-off state, the pressing device 200 being in a gas-off state, the pressing device 200 being in a manual state, the pressing device 200 being in a maintenance state, and the pressing device 200 being in an alarm state.

[0097] Any of the above abnormal conditions may cause the pressing device 200 to continue the pressing action in an uncontrolled state. Therefore, when the above abnormal conditions occur, the pressing device 200 needs to be repaired in time. Among them, the power-off state means that the pressing device 200 loses power supply during operation and cannot operate normally. The air-off state means that the pressing device 200 loses air supply during operation and cannot operate normally. The manual state means that the position of the part to be extruded needs to be manually adjusted during operation of the pressing device 200, thereby interrupting the operation of the pressing device 200. The maintenance state means that the pressing device 200 needs to be shut down for maintenance. The alarm state means that an error occurs during the operation of the pressing device 200 and the system sends an alarm signal.

[0098] When the pressing device 200 is in any of the above abnormal states, there is a risk of the pressing device 200 automatically pressing down. By controlling the limit mechanism 20 to move to the second position and making the limit member 21 abut against the movable end 202, the phenomenon of the pressing device 200 automatically pressing down in an uncontrolled state can be reduced, thereby reducing safety hazards. Combination Figures 1 to 7 As shown, in some embodiments of the present application, the pressing method further includes the following steps: According to the limiting mechanism 20 being in the first position, a first detection signal is issued, and the movable end 202 of the pressing device 200 is driven to press downward; And / or, according to the limiting mechanism 20 being in the second position, a second detection signal is issued, and the pressing device 200 is inspected and repaired.

[0099] Specifically, the pressing protection device 100 may include a first detection member 41 and a second detection member 42. When the limiting mechanism 20 is in the first position, the first detection member 41 sends a first detection signal to remind the operator that the limiting member 21 is separated from the movable end 202, and the pressing device 200 can be operated to perform a pressing action. When the limiting mechanism 20 is in the second position, the second detection member 42 sends a second detection signal to remind the operator that the limiting member 21 is in contact with the movable end 202 and limits the pressing action of the movable end 202, so that the pressing device 200 can be inspected and repaired.
