Description

Technical Field

[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 in maintenance or shutdown state, thereby posing a risk of crushing injuries to the operator. Summary of the Invention

[0003] In view of the defects of the prior art, the purpose of this application is to provide a downward pressure protection device, a downward pressure system and a downward pressure method, which can effectively solve the problem of the downward pressure device automatically pressing down in an uncontrolled state:

[0004] 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, comprising:

[0005] A driving mechanism, the driving mechanism comprising a first driving member,

[0006] 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 pressing action of the movable end, wherein the first direction intersects with the second direction.

[0007] 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, thereby separating the limiting member 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, thereby making the limiting member abut against the movable end, and being used to limit the downward pressure action of the movable end along the first direction, thereby reducing the phenomenon of the downward pressure device automatically pressing down in an uncontrolled state and reducing safety hazards.

[0008] 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.

[0009] When the limit member abuts against the movable end and is used to limit the downward pressing action 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. At the same time, 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 pressing process.

[0010] 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.

[0011] By setting the buffer as an elastic buffer and being able 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 limit member is separated from the movable end, the buffer member can return to its original state through its own elastic deformation, thereby driving the limit member to return to its original position so as to limit the downward pressing action of the movable end again.

[0012] In some embodiments of the present application, the limiting mechanism also includes a mounting seat assembly, which is connected to the first driving member. The mounting seat assembly is configured to be able to move back and forth 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.

[0013] The limiting mechanism can be connected to the first driving member through the mounting seat assembly, so that it can move back and forth 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.

[0014] 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.

[0015] By arranging the limiting member and the buffer member on both sides of the mounting seat assembly along the first direction respectively, the overall structural setting of the limiting mechanism is facilitated, and the problem of one side of the mounting seat assembly being too large due to the limiting member and the buffer member being arranged on one side of the mounting seat assembly, thereby affecting installation, is reduced.

[0016] 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.

[0017] 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 along 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.

[0018] 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, a first mounting hole is passed through the sleeve along the 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.

[0019] The support rod can be inserted into the first mounting hole of the shaft sleeve along a first direction, thereby connecting the buffer assembly to the mounting seat assembly. When the support rod reciprocates in the first direction multiple times, the contact surface between the mounting seat assembly and the support rod is likely to wear. Because the support rod is inserted into the shaft sleeve, only the inner wall surface of the shaft sleeve is worn, and the inner wall surface of the seat body is not worn. Therefore, only the shaft sleeve needs to be replaced without replacing the seat body.

[0020] In some embodiments of the present application, at least one end of the sleeve protrudes from the seat body along the first direction, and the mounting seat assembly is further provided with a positioning member, which is provided on the seat body and is used to limit the movement of the sleeve along the first direction.

[0021] 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 caused by the sleeve moving together with the support rod and separating from the seat during the movement of the support rod can be reduced.

[0022] 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.

[0023] By sleeve-mounted on the end of the support rod, the positioning connection between the limiter and the support rod is achieved. At the same time, the limiter is protruded from the outer peripheral surface of the sleeve so that the movable end can be hooked on the side of the limiter facing the sleeve, thereby limiting the movement of the movable end along the first direction through the limiter.

[0024] In some embodiments of the present application, the downward pressure protection device further includes a support mechanism, the first driving member is connected to the support mechanism, and the support mechanism is configured to be connectable to the downward pressure device.

[0025] The first driving member can be connected to the supporting mechanism, so that the entire downward pressure protection device is connected to the downward pressure device through the supporting mechanism, thereby facilitating the fixing of the downward pressure protection device and being used to limit the downward pressure action of the movable end.

[0026] In some embodiments of the present application, the downward pressure protection device further includes a detection mechanism, which is configured to be connectable to the downward pressure device and used to detect whether the limiting mechanism is in the first position and / or the limiting mechanism is in the second position.

[0027] 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 downward 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 downward pressing action of the movable end so that the downward pressing device can be repaired and operated.

[0028] In some embodiments of the present application, the detection mechanism includes a first detection member and a second detection member, and the first detection member and the second detection member are respectively configured to be connected to the pressing device, and 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.

[0029] 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.

[0030] On the second aspect, the present application also proposes a downward pressure system, including any of the above-mentioned downward pressure protection devices, the downward pressure system also includes a downward pressure device, the downward pressure 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 the 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 pressure action of the movable end.

[0031] 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.

[0032] In some embodiments of the present application, the pressing device further includes a fixed end, the second driving member is provided 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.

[0033] The fixed end can be used to fix the second driving member, so that the second driving member drives the movable end to perform a downward pressing action along the first direction.

[0034] In a third aspect, the present application further proposes a downward pressing method, which is applied to any of the above downward pressing systems, comprising:

[0035] According to the abnormal state of the pressing device and the failure of the movable end to complete the pressing action, the limiting mechanism is controlled to move to the second position;

[0036] Handling abnormal conditions;

[0037] 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.

[0038] 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.

[0039] In some embodiments of the present application, the abnormal state includes at least one of the pressure device being in a power-off state, the pressure device being in a gas-off state, the pressure device being in a manual state, the pressure device being in a maintenance state, and the pressure device being in an alarm state.

[0040] When the pressing device is in any of the above abnormal states, there is a risk that the pressing device will automatically press 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.

[0041] In some embodiments of the present application, the pressing method further comprises the following steps:

[0042] According to the limiting mechanism being in the first position, a first detection signal is issued, and the movable end of the pressing device is driven to press downward;

[0043] And / or, according to the limiting mechanism being in the second position, a second detection signal is issued, and the pressing device is inspected and repaired.

According to the limit mechanism being in the second position and sending out the second detection signal, the personnel can be reminded that the limit member is in contact with the movable end and limits the pressing action of the movable end, so that the pressing device can be inspected and repaired.

[0072] A pressing device with a pressing function may automatically press down in an uncontrolled state when in maintenance or shutdown state, thereby posing a risk of crushing injuries to the operator.

[0073] 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.

[0074] Combine 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.

[0075] Specifically, the pressing device 200 includes a second driving member 201 and a movable end 202. The movable end 202 is connected to the output end of the second driving member 201 and can perform a pressing action in a 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 other shaped structure 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. The cylinder rod of the second driving member 201 is connected to the connecting block 2023, so that under the action of the second driving member 201, the pressing head 2021 is driven to perform a pressing action in the first direction X. 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 in the vertical direction. In some other embodiments of the present application, the pressing head 2021 may be directly connected to the output end of the second driving member 201 .

[0076] The downward pressure protection device 100 includes a drive mechanism 10 and a limiting mechanism 20. The drive mechanism 10 includes a first drive member 11. The output end of the first drive member 11 is connected to the limiting mechanism 20, thereby being used to drive the limiting mechanism 20 to move back and forth along the second direction Y. The limiting mechanism 20 has a first position and a second position during 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 separates from the movable end 202, allowing the downward pressure device 200 to operate normally and complete 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 of the downward pressure device 200 automatically pressing down in an uncontrolled state and 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. The cylinder rod of the first driving member 11 may be connected to the limiting mechanism 20 via the connecting plate 12, 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 surface of the side of the movable plate 2022 facing away from the second driving member 201, thereby limiting the downward movement of the movable plate 2022.

[0077] According to the downward pressure protection device 100 of the present application, when the downward pressure device 200 is operating 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 can operate normally and complete 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 in contact with 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.

[0078] Combine 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.

[0079] Specifically, the buffer member 221 has a certain degree of deformation capability. Therefore, when the position-limiting member 21 moves along the first direction X, the deformation of the buffer member 221 reduces the movement speed of the position-limiting member 21, thereby achieving the purpose of reducing impact. Optionally, the buffer member 221 can be compressed or stretched during the movement of the position-limiting member 21 along the first direction X, depending on the specific configuration.

[0080] When the limiting member 21 abuts against 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. At the same time, the buffer member 221 can deform 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.

[0081] Combine 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.

[0082] 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 return 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.

[0083] Combine Figures 1 to 6 As 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. The mounting seat assembly 23 is configured to be able to move back and forth 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 can move along the first direction X.

[0084] 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 moves back and forth along the second direction Y under the action of the first driving member 11 and abuts against or separates from the movable end 202 .

[0085] The limiting mechanism 20 can be connected to the first driving member 11 through the mounting seat assembly 23, so that it can move back and forth 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.

[0086] Combine 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.

[0087] Specifically, the limiter 21 and the buffer 221 are respectively provided on opposite sides of the mounting seat assembly 23 along the first direction X. Optionally, the limiter 21 can be provided below the mounting seat assembly 23 along the vertical direction, and the buffer 221 can be provided above the mounting seat assembly 23 along the vertical direction.

[0088] By arranging the limiting member 21 and the buffer member 221 on both sides of the mounting seat assembly 23 along the first direction X respectively, the overall structural setting of the limiting mechanism 20 is facilitated, and the problem of one side of the mounting seat assembly 23 being too large due to the limiting member 21 and the buffer member 221 being arranged on one side of the mounting seat assembly 23, thereby affecting the installation, is reduced.

[0089] Combine Figures 1 to 6 As shown, in some embodiments of the present application, the buffer assembly 22 further includes a support rod 222 and a fixing member 223. The support rod 222 is arranged in 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.

[0090] Specifically, the support rod 222 is a rod-shaped structure, axially arranged along a first direction X, and extending through the mounting assembly 23 along the first direction X. A stopper 21 is provided on one side of the support rod 222 located on the mounting assembly 23, and a fixing member 223 is provided on the other side of the support rod 222 located on the mounting assembly 23, with the fixing member 223 protruding from the outer circumference of the support rod 222. The buffer member 221, which may be a spring, is sleeved around the exterior of the support rod 222 and sandwiched between the fixing member 223 and the mounting assembly 23 along the first direction X. When the stopper 21 abuts the movable end 202 and moves downward or tends to move downward under the downward pressure of the movable end 202, it compresses the buffer member 221, thereby reducing the impact force. Optionally, the fixing member 223 and the support rod 222 may be connected by a connecting bolt 24, which passes through the fixing member 223 and the support rod 222 in sequence along the first direction X.

[0091] 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 along 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 return to its original state through its own elastic deformation, thereby driving the limiting member 21 to return to its original position.

[0092] Combine 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.

[0093] Specifically, the base 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 base 231 through the shaft sleeve 232, thereby reciprocating along the second direction Y with the base 231. Optionally, a through hole can be provided on the base 231 along the first direction X, and the shaft sleeve 232 can be inserted into the through hole of the base 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 provided on both sides of the base 231. In some embodiments of the present application, the shaft sleeve 232 can also be provided on the outside of the base 231 and connected to the outer surface of the base 231.

[0094] The support rod 222 can be inserted into the first mounting hole of the shaft sleeve 232 along the first direction X, thereby connecting the buffer assembly 22 to the mounting seat assembly 23. After the support rod 222 reciprocates multiple times along the first direction X, the contact surface between the mounting seat assembly 23 and the support rod 222 can easily wear. Because the support rod 222 is inserted into the shaft sleeve 232, only the inner wall surface of the shaft sleeve 232 wears, and the inner wall surface of the seat body 231 does not wear. Therefore, only the shaft sleeve 232 needs to be replaced without replacing the seat body 231.

[0095] Combine Figures 1 to 6 As shown, in some embodiments of the present application, the sleeve 232 is arranged to protrude from the seat body 231 at least at one end along the first direction X, and the mounting seat assembly 23 is also provided with a positioning member 233, which is arranged on the seat body 231 and is used to limit the movement of the sleeve 232 along the first direction X.

[0096] Specifically, the top of the sleeve 232 can protrude beyond the base 231 and, by connecting to the positioning member 233, fix the position of the sleeve 232 along the first direction X, thereby reducing movement of the sleeve 232 along the first direction X. Optionally, the top of the sleeve 232 protruding beyond the base 231 is partially recessed to provide a plug-in slot 2321. The positioning member 233 can be a sheet-like structure and fixed to the base 231 via bolts. The partially sheet-like positioning member 233 is inserted into the plug-in slot 2321, thereby positioning the sleeve 232 along the first direction X.

[0097] By setting 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.

[0098] Combine Figures 1 to 6 As shown, in some embodiments of the present application, the limiting member 21 includes a sleeve portion 211 and a limiting portion 212. The sleeve portion 211 is sleeved on one end of the support rod 222 along its own axial direction away from the fixing member 223. The limiting portion 212 protrudes from the outer peripheral surface of the sleeve portion 211. The limiting portion 212 is configured to be able to abut against the movable end 202 when the limiting mechanism 20 is in the second position.

[0099] Specifically, the limiting member 21 includes a sleeve portion 211 and a limiting portion 212, which are sequentially arranged along the first direction X. The sleeve portion 211 is a generally cylindrical structure with a mounting hole provided therein along its axial direction. The lower end of the support rod 222 is inserted into the mounting hole of the sleeve portion 211, thereby fitting the sleeve portion 211 onto the exterior of the support rod 222. Simultaneously, the lower end of the sleeve portion 211 is provided with a limiting portion 212, which protrudes from the outer circumference of the sleeve portion 211, thereby forming a step-like structure at the connection between the sleeve portion 211 and the limiting portion 212. This step-like structure can cooperate with the lower end of the movable end 202, thereby limiting the downward movement of the movable end 202. Optionally, the movable end 202 includes a movable plate 2022, with a first notch 20221 provided on one side of the movable plate 2022 along the second direction Y. The sleeve portion 211 can be inserted into the first notch 20221 along the second direction Y, and the limiting portion 212 is positioned below the movable plate 2022 and abuts against the lower surface of the movable plate 2022, thereby limiting the downward movement of the movable end 202 along the first direction X. Optionally, the limiting member 21 can be connected to the support rod 222 via a connecting bolt 24, which can pass through the limiting portion 212 and the support rod 222 in sequence along the first direction X.

[0100] By sleeve portion 211 being sleeved on the end portion of 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.

[0102] Specifically, the support mechanism 30, the drive mechanism 10, and the limiting mechanism 20 are sequentially connected, so that the entire downward pressure protection device 100 can be installed through the support mechanism 30. The support mechanism 30 is configured to be connected to the downward pressure device 200, thereby connecting the downward pressure protection device 100 to the downward pressure device 200 and facilitating the limiting of the movable end 202 of the downward pressure device 200.

[0103] Optionally, the support mechanism 30 includes a first support plate 31, a second support plate 32, and a third support plate 33 connected in sequence. The length direction of the first support plate 31 is perpendicular to the first direction X and the second direction Y, respectively. The first driving member 11 can be fixedly mounted on the first support plate 31, thereby facilitating the first driving member 11 to be positioned on one side of the pressing device 200 along the second direction Y and capable of driving the limiting member 21 to move along the second direction Y. The length direction of the second support plate 32 is consistent with the second direction Y. One end of the second support plate 32 in the length direction is connected to the first support plate 31, and the other end of the second support plate 32 in the length direction is connected to the pressing device 200 via the third support plate 33, thereby spacing the first support plate 31 from the pressing device 200 along the second direction Y. Optionally, to improve the support stability of the first support plate 31, a second support plate 32 is provided at each end of the first support plate 31 in the length direction. Optionally, the third support plate 33 is connected to the pressing device 200 by bolts, and the third support plate 33 is provided with a plurality of connecting holes arranged along the first direction X, or a long hole extending along the first direction X, so that the relative position of the support mechanism 30 and the pressing device 200 along the first direction X can be adjusted through the third support plate 33, thereby adjusting the relative position of the limit member 21 and the movable end 202 along the first direction X in the initial state.

[0104] Optionally, the support mechanism 30 further includes a reinforcing plate 34, which is used to connect the second support plate 32 and the third support plate 33, thereby improving the support strength of the support mechanism 30. Optionally, the reinforcing plate 34 can be a triangular plate structure, one right-angled side of which is connected to the second support plate 32, and the other right-angled side of which is connected to the third support plate 33, and the connection method can be welding.

[0105] The first driving member 11 can be connected to the supporting mechanism 30 , so that the entire downward pressure protection device 100 is connected to the downward pressure device 200 through the supporting mechanism 30 , thereby facilitating the fixing of the downward pressure protection device 100 and limiting the downward pressure of the movable end 202 .

[0106] Combine Figures 1 to 6As shown, in some embodiments of the present application, the down-pressing protection device 100 further includes a detection mechanism 40, which is configured to be connectable to the down-pressing device 200 and used to detect whether the limiting mechanism 20 is in the first position and / or the limiting mechanism 20 is in the second position.

[0107] Specifically, the detection mechanism 40 is used to detect the position of the limiting mechanism 20, including detecting whether the limiting mechanism 20 is in the first position or detecting whether the limiting mechanism 20 is in the second position. Optionally, the detection mechanism 40 includes a detector, which can be a touch sensor or a non-contact sensor, including an infrared sensor or a laser sensor.

[0108] The detection mechanism 40 detects that the limit mechanism 20 is in the first position, thereby determining that the limit member 21 is separated from the movable end 202, so that the downward pressing action can be performed. The detection mechanism 40 detects that the limit mechanism 20 is in the second position, thereby determining that the limit member 21 is in contact with the movable end 202, and is used to limit the downward pressing action of the movable end 202, so that the downward pressing device 200 can be repaired and operated.

[0109] Combine Figures 1 to 6 As shown, in some embodiments of the present application, the detection mechanism 40 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 respectively configured to be connected to the pressing device 200, and the first detection member 41 and the second detection member 42 are arranged at intervals along the second direction Y. The first detection member 41 is configured to detect that the limiting mechanism 20 is in the first position, and the second detection member 42 is configured to detect that the limiting mechanism 20 is in the second position.

[0110] 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. When the limiting mechanism 20 is in the first position, the first detection member 41 sends a first detection signal, and when the limiting mechanism 20 is in the second position, the second detection member 42 sends a second detection signal, thereby reminding the operator of the position of the limiting mechanism 20. Optionally, the detection signal can be an alarm light or an alarm bell. Optionally, the first detection member 41 and the second detection member 42 can be infrared sensors respectively, and are at the same height position as the fixing member 223 along the first direction X. When the limiting mechanism 20 is in the first position, the first detecting member 41 is arranged horizontally opposite to the fixing member 223, and the detection signal emitted by the first detecting member 41 can act on the fixing member 223, thereby determining that the limiting mechanism 20 is in the first position. When the limiting mechanism 20 is in the second position, the second detecting member 42 is arranged horizontally opposite to the fixing member 223, and the detection signal emitted by the second detecting member 42 can act on the fixing member 223, thereby determining that the limiting mechanism 20 is in the second position.

[0111] In some embodiments of the present application, the detection mechanism 40 also includes a mounting plate 43, the first detection member 41 and the second detection member 42 are respectively arranged on the mounting plate 43, and the mounting plate 43 is connected to the pressing device 200. Optionally, the pressing device 200 also includes a fixed end 203, the fixed end 203 includes a fixed plate 2031, the fixed plate 2031 and the movable plate 2022 can be spaced apart along the first direction X, the second driving member 201 is located 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, thereby completing the pressing action when the movable end 202 moves in the direction away from the fixed plate 2031. Wherein, the mounting plate 43 is fixed on the fixed plate 2031, and the mounting plate 43 can be an L-shaped plate, including a first plate portion arranged in the horizontal direction and a second plate portion arranged in the vertical direction. Wherein, the first plate portion is fitted and connected to the fixed plate 2031, and the second plate portion is used to install and fix the first detection member 41 and the second detection member 42. Optionally, a second notch 20311 is provided on one side of the fixing plate 2031 along the second direction Y, and the support rod 222 can be inserted into the second notch 20311 along the second direction Y, and the fixing member 223 is provided above the fixing plate 2031 and can be arranged opposite to the first detection member 41 or the second detection member 42.

[0112] By providing the first detecting member 41 and the second detecting member 42 , it is possible to accurately detect whether the limiting mechanism 20 is in the first position or the second position, thereby determining whether the pressing device 200 is in operation or maintenance.

[0113] Combine Figures 1 to 6 As shown, in the second aspect, the present application also 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 further 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.

[0114] Specifically, the second driving member 201 can be a driving cylinder, and the movable end 202 includes a downward pressure head 2021, a movable plate 2022 and a connecting block 2023 connected in sequence. The cylinder rod of the second driving member 201 is connected to the connecting block 2023, so that under the action of the second driving member 201, the downward pressure head 2021 is driven to perform a downward action along the first direction X.

[0115] According to the pressing system 1000 of the present application, when the pressing device 200 is operating 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 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 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 in contact with 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 and reducing safety hazards.

[0116] Combine 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 provided 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 .

[0117] Specifically, the fixed end 203 includes a fixed plate 2031. The fixed plate 2031 and the movable plate 2022 can be spaced apart along the first direction X. The second driving member 201 is disposed on the fixed plate 2031. Under the action of the second driving member 201, the movable end 202 can move relative to the fixed plate 2031 along the first direction X, thereby achieving downward pressure when the movable end 202 moves in a direction away from the fixed plate 2031. The fixed end 203 also includes a guide rod 2032. The guide rod 2032 includes a fixed portion and a sliding portion. The fixed portion is fixedly disposed on the fixed plate 2031. The sliding portion is connected to the fixed plate 2031 in a manner that allows it to slide along the first direction X. The end of the sliding portion along the first direction X is connected to the movable plate 2022. Therefore, when the second driving member 201 drives the movable plate 2022 to perform a downward pressure action, the sliding portion can slide relative to the fixed portion along the first direction X, thereby improving the smoothness of the downward pressure action.

[0118] Combine 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:

[0119] According to the abnormal state of the pressing device 200 and the incomplete pressing action of the movable end 202, the limiting mechanism 20 is controlled to move to the second position;

[0120] Handling abnormal conditions;

[0121] 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 .

[0122] 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 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. Because the limiter 21 can limit the downward pressure of the movable end 202, the abnormal state can be handled at this time, and the safety hazard caused by the downward pressure 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 to continue to complete the downward pressure action or return the movable end 202 to the initial position for the next downward pressure action. Among them, the detection component of the downward pressure device 200 itself can detect whether the movable end 202 has moved to a specified position along the first direction X, thereby determining whether the movable end 202 has completed the downward pressure action. Optionally, the downward pressure device 200 and the downward pressure protection device 100 can be controlled by the same control system, so that the operating state of the downward pressure protection device 100 is automatically controlled according to the operating state of the downward pressure 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 .

[0123] 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.

[0124] Combine 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.

[0125] Any of the above abnormal conditions may cause the pressing device 200 to continue pressing down 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, 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.

[0126] When the pressing device 200 is in any of the above abnormal states, there is a risk that the pressing device 200 will automatically press 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.

[0127] Combine Figures 1 to 7 As shown, in some embodiments of the present application, the pressing method further includes the following steps:

[0128] 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;

[0129] 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.

[0130] Specifically, the downward pressure 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 emits a first detection signal to alert the operator that the limiting member 21 is separated from the movable end 202, allowing the downward pressure device 200 to be operated. When the limiting mechanism 20 is in the second position, the second detection member 42 emits a second detection signal to alert the operator that the limiting member 21 is in contact with the movable end 202, restricting the downward pressure of the movable end 202, thereby allowing the downward pressure device 200 to be inspected and repaired.
