Description

Working pressure protection system The present application relates to the technical field of operating pressure protection, and in particular to an operating pressure protection system. With the advancement of industrial production, workpieces are becoming thinner and thinner. During the production or installation of workpieces, if the pressure exerted by the workpiece is too great, it may cause damage to the workpiece. In view of this, the present application provides an operating pressure protection system to solve the problem of workpiece damage caused by excessive pressure during operation on the workpiece. One embodiment of the present application provides an operating pressure protection system, including a base, a pressure sensing component, a workbench, an operating component and a driving component. The pressure sensing component is arranged on the base. The workbench is movably arranged on the base and is used to carry a workpiece. The workbench can move along a first direction close to the pressure sensing component so that the pressure sensing component senses the pressure of the workbench. The operating component is movably arranged on the base and is used to operate on the workpiece. The operating component can move along a first direction close to the workbench. The driving component is arranged on the base. The pressure sensing component and the driving component are electrically connected. When the pressure value sensed by the pressure sensing component reaches a set value, the driving component can drive the operating component to move away from the workbench along the first direction. In the above-described embodiment, the working assembly operates on a workpiece supported by a worktable. The worktable is movable relative to the base, enabling the working assembly to move when exerting pressure on the workpiece. The pressure is then transferred from the worktable, converting the pressure exerted by the working assembly on the workpiece into pressure exerted by the worktable on the pressure-sensing assembly. Therefore, by comparing the pressure sensed by the pressure-sensing assembly with a set value, it is determined whether the pressure exerted by the working assembly on the workpiece is excessive. When the pressure exerted by the working assembly on the workpiece reaches an upper limit, the driving assembly drives the working assembly away from the worktable, reducing the pressure exerted on the workpiece. This prevents damage to the workpiece caused by excessive pressure exerted by the working assembly. In some embodiments of the present application, the operating pressure protection system further includes an elastic component having one end connected to the base and the other end connected to or abutting against the workbench, capable of applying a force to the workbench in a first direction away from the pressure sensing component. In the above embodiment, the workbench is movably connected to the base via an elastic component, so that the workbench can be moved away from the pressure sensing component with the help of elastic force. On the one hand, after the working component moves away from the workbench, the workbench can be reset, so there is no need to adjust the set value compared by the pressure sensing component; on the other hand, the workbench can hover relative to the base to keep the position of the workbench carrying the workpiece stable, which facilitates repeated operations of the working component on the workbench, and the operator does not need to adjust the operating habits of using the working pressure protection system. In some embodiments of the present application, when the operating component is not operating on the workpiece, the workbench is supported by the elastic component and a gap can be formed between the workbench and the pressure sensing component. In the above embodiment, there is a gap between the workbench and the pressure sensing component, so the pressure sensing component is not subjected to pressure and is free from work, thereby avoiding fatigue of the pressure sensing component causing inaccurate sensed pressure values. Therefore, when the working component is not operating on the workpiece, the pressure sensing component can rest. In some embodiments of the present application, the elastic component includes a slide rail, a slider, and an elastic member. The slide rail is disposed on a base. The slider is slidably connected to the slide rail along a first direction. The slider is connected to or abuts a workbench. One end of the elastic member is connected to or abuts the base or the slide rail, and the other end of the elastic member is connected to or abuts the slider, and is capable of applying a force to the slider in the first direction away from the pressure sensing component. In the above embodiment, the movement direction and movement path of the workbench relative to the base are limited by the cooperation of the slider and the slide rail to prevent the workbench from shaking; the base and the slide rail are relatively fixed, and the elastic member acts on the slider, and the slider transmits the force of the elastic member to the workbench, so that the workbench can be reset or hover relative to the base. In some embodiments of the present application, the operating pressure protection system includes a detection member configured to detect a status of a workbench. The detection member is electrically connected to a drive assembly. When the detection member detects that the workbench allows the operating assembly to operate, the drive assembly can drive the operating assembly to move in a first direction away from the workbench. In the above embodiment, the detection component is used to determine whether the operating component can operate on the workpiece, thereby preventing the driving component from mistakenly driving the operating component when the excessive pressure sensed by the pressure sensing component is not caused by the excessive pressure of the operating component on the workpiece, preventing the operating pressure protection system from being affected by interference factors, and thus ensuring that the operating pressure protection system can be used stably to limit the operating pressure of the workpiece. In some embodiments of the present application, the operating pressure protection system further includes a fixing member and a locking member. The fixing member is rotatably connected to the workbench. The locking member is disposed on the workbench. The locking member can lock the fixing member so that the workbench allows the operating assembly to operate. In the above embodiment, the fixing member fixes the workpiece on the workbench when the locking member is locked. The working component can operate on the workpiece only after the workbench fixes the workpiece. Therefore, after the locking member locks the fixing member, the driving component decides whether to drive the working component to move based on the pressure value sensed by the pressure sensing component. In some embodiments of the present application, a work assembly includes a work piece and a work frame. The work piece is mounted on the work frame. The work piece is used to perform work on a workpiece on a workbench. The work frame is slidably connected to a base along a first direction. A drive assembly is capable of driving the work frame to move away from the workbench in the first direction, thereby driving the work piece away from the workbench in the first direction. In the above embodiment, the workpiece is working on the workbench, so that the pressure sensing component senses the pressure of the workbench to determine the working pressure applied to the workpiece. The driving component drives the workpiece away from the workpiece by driving the work frame to move. The working component is used to separate the part where the work is performed from the part driven to move by the driving component, so that the working component's operation on the workpiece is not affected by the structure of the driving component. In some embodiments of the present application, the operating pressure protection system further includes a support rod. The support rod is disposed on the base and extends in a first direction. The operating frame includes a plurality of connecting rods that are rotatably connected in sequence. The first of the plurality of connecting rods is sleeved on the support rod, and the last of the connecting rods is connected to the operating member. In the above embodiment, the first connecting rod is mounted on the support rod, so that the work frame can slide along the support rod and rotate around the support rod. Then, through the rotation relationship between the multiple connecting rods, the work piece can not only move in the first direction, but also in a direction perpendicular to the first direction, which makes it easier for the operator to move the work piece to operate on the workpiece. In some embodiments of the present application, the operating pressure protection system also includes a processor, which includes a control module, a display module, an alarm module and a recording module. The control module is telecommunication-connected to the pressure sensing component to receive the pressure value sensed by the pressure sensing component, the control module is telecommunication-connected to the driving component to control the driving action of the driving component on the operating component, the control module is telecommunication-connected to the alarm module to control the alarm module to alarm, and the control module is telecommunication-connected to the recording module to record the situation where the sensed pressure value exceeds the set value. In the above embodiment, the control module determines whether the operating pressure applied to the workpiece is too high, and further decides whether to allow the driving component to drive the operating component away from the workpiece; the control module can control the display module to display the pressure value applied by the operating component when operating on the workpiece; the control module can control the alarm module to alarm when the operating pressure applied to the workpiece is too high, so as to warn the operator; the control module can control the recording module to record the situation where the operating pressure applied to the workpiece is too high, so as to realize the monitoring of the workpiece operation process. In some embodiments of the present application, the operating pressure protection system further includes a protection block disposed on the base, and the protection block at least partially extends to a side of the workbench away from the pressure sensing component in the first direction. In the above embodiment, the protective block can prevent the operator from accidentally touching the workbench when operating the workpiece, which may cause the driving component to drive the working component away from the workpiece. It also makes it convenient for the operator to support his arm on the protective block when controlling the working component to operate, thereby saving effort. The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the listed items. An embodiment of the present application provides an operating pressure protection system, comprising a base, a pressure sensing component, a workbench, an operating component and a drive component. The pressure sensing component is disposed on the base. The workbench is movably disposed on the base and is used to carry a workpiece. The workbench can move along a first direction close to the pressure sensing component so that the pressure sensing component senses the pressure of the workbench. The operating component is movably disposed on the base and is used to operate on the workpiece. The operating component can move along a first direction close to the workbench. The drive component is disposed on the base. The pressure sensing component is electrically connected to the drive component. When the pressure value sensed by the pressure sensing component reaches a set value, the drive component can drive the operating component to move away from the workbench along the first direction. The working assembly operates on the workpiece carried by the worktable. The worktable is movable relative to the base, enabling the working assembly to move when it exerts pressure on the workpiece. The pressure is then transferred from the worktable, converting the pressure exerted by the working assembly on the workpiece into pressure exerted by the worktable on the pressure-sensing assembly. By comparing the pressure sensed by the pressure-sensing assembly with the set value, it is determined whether the pressure exerted by the working assembly on the workpiece is excessive. When the pressure exerted by the working assembly on the workpiece reaches an upper limit, the driving assembly drives the working assembly away from the worktable, reducing the pressure exerted on the workpiece. This prevents damage to the workpiece caused by excessive pressure exerted by the working assembly. The following describes some embodiments of the present application in detail with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other unless there is any conflict. Referring to Figures 1, 2 and 4, one embodiment of the present application provides an operating pressure protection system 100, including a base 1, a pressure sensing component 2, a workbench 3, an operating component 4 and a driving component 5. The pressure sensing component 2 is arranged on the base 1. The workbench 3 is movably arranged on the base 1 and is used to carry a workpiece. The workbench 3 can move along a first direction A close to the pressure sensing component 2 so that the pressure sensing component 2 senses the pressure of the workbench 3. The operating component 4 is movably arranged on the base 1 and is used to operate on the workpiece. The operating component 4 can move along a first direction A close to the workbench 3. The driving component 5 is arranged on the base 1. The pressure sensing component 2 is electrically connected to the driving component 5. When the pressure value sensed by the pressure sensing component 2 reaches a set value, the driving component 5 can drive the operating component 4 to move along the first direction A away from the workbench 3. Working assembly 4 operates on the workpiece carried by worktable 3. Worktable 3 is movable relative to base 1, enabling working assembly 4 to move when exerting pressure on the workpiece. This pressure is then transferred from worktable 3, converting the pressure exerted by working assembly 4 on the workpiece into pressure exerted by worktable 3 on pressure-sensing assembly 2. By comparing the pressure sensed by pressure-sensing assembly 2 with the set value, it is determined whether the pressure exerted by working assembly 4 on the workpiece is excessive. When the pressure exerted by working assembly 4 on the workpiece reaches an upper limit, driving assembly 5 drives working assembly 4 away from worktable 3, reducing the pressure exerted on the workpiece. This prevents excessive pressure exerted by working assembly 4 on the workpiece, which could damage the workpiece. A telecommunications connection refers to a wired or wireless connection that can achieve either electrical or signal connectivity. Referring to FIG2 , in some embodiments, an operating pressure protection system 100 is used to perform screw tightening operations on a workpiece. A workbench 3 is used to secure the workpiece, and an operating assembly 4 is used to clamp and tighten the screw onto the workpiece on the workbench 3 . The screw is tightened into the workpiece without requiring significant pressure from the operating assembly 4 . However, if the operating pressure from the operating assembly 4 on the screw is excessive, this pressure is transmitted as the operating assembly 4 exerting significant pressure on the workpiece. Under the transmission of pressure from the workbench 3 , the pressure sensing assembly 2 senses the excessive pressure from the workbench 3 , and the drive assembly 5 drives the operating assembly 4 away from the workbench 3 , thereby moving the operating assembly 4 away from the workpiece. The operating assembly 4 then ceases screw tightening operations on the workpiece, protecting the workpiece from excessive pressure and preventing damage. In some embodiments, the first direction A is parallel to the direction of gravity, thereby achieving the limitation and protection of the vertical force exerted by the control operating component 4 on the workpiece. In some embodiments, the set value for comparison with the pressure value sensed by the pressure sensing component 2 is adaptively adjusted according to the operational requirements of different workpieces. In some embodiments, the workpiece is a structure that requires operating pressure, such as a motherboard, a housing, or a screen panel of an electronic device. It is understood that the workpiece is not limited to the above structures. Referring to Figures 2-4 , in some embodiments, the operating pressure protection system 100 further includes an elastic component 6. One end of the elastic component 6 is connected to the base 1, and the other end is connected to or abuts the workbench 3. The elastic component 6 is capable of applying a force to the workbench 3 in a first direction A, away from the pressure sensing component 2. The workbench 3 is movably connected to the base 1 via the elastic component 6, allowing the workbench 3 to move away from the pressure sensing component 2 by virtue of the elastic force. This allows the workbench 3 to return to its original position after the operating component 4 moves away from the workbench 3, eliminating the need to adjust the set value of the pressure sensing component 2. Furthermore, the workbench 3 can hover relative to the base 1, maintaining a stable position for the workpiece supported by the workbench 3. This facilitates repeated operation of the workbench 3 by the operating component 4, without requiring the operator to adjust their operating habits when using the operating pressure protection system 100. It is understood that in some embodiments, the pressure sensing component 2, the workbench 3, the operating component 4, and the elastic component 6 are all located on the same side of the base 1 in the first direction A, and are all located above the base 1 in the direction of gravity. In other embodiments, the elastic element 6 may be omitted. The worktable 3 can be moved in the first direction A away from the pressure-sensing element 2 by providing a separate driving component, thereby enabling pressure limitation and protection for the next operation. Alternatively, after the elastic element 6 drives the operating element 4 away from the worktable 3, the corresponding increase in pressure on the worktable 3 disappears, and the pressure sensed by the pressure-sensing element 2 is no longer excessive, allowing the next operation to be directly limited and protected. Referring to Figures 2-4 , in some embodiments, when the working component 4 is not operating on a workpiece, the worktable 3, supported by the elastic component 6, forms a gap 31 with the pressure sensing component 2. The gap 31 between the worktable 3 and the pressure sensing component 2 protects the pressure sensing component 2 from pressure and prevents it from operating. This prevents fatigue and inaccurate pressure readings from the pressure sensing component 2. Thus, when the working component 4 is not operating on a workpiece, the pressure sensing component 2 can rest. In some embodiments, the gap 31 between the worktable 3 and the pressure sensing component 2 is 0.3 mm to 0.5 mm. This allows the pressure sensing component 2 to remain in a state of sensing pressure while the working component 4 applies a certain amount of pressure to the workpiece. Furthermore, if the working component 4 applies a high pressure to the workpiece, the worktable 3 can contact the pressure sensing component 2 and determine the pressure applied by the working component 4. It is understandable that in other embodiments, for different workpieces, or different operating requirements, or different operating methods, the size of the gap 31 needs to be adaptively changed and not limited to the above range to avoid excessive pressure exerted by the operating component 4 on the workpiece. Referring to Figures 1 to 3, in some embodiments, the elastic component 6 includes a slide rail 61, a slider 62, and an elastic member 63. The slide rail 61 is provided on the base 1. The slider 62 is slidably connected to the slide rail 61 along the first direction A. The slider 62 is connected to or abuts the workbench 3. One end of the elastic member 63 is connected to or abuts the base 1 or the slide rail 61, and the other end of the elastic member 63 is connected to or abuts the slider 62, and is capable of applying a force to the slider 62 away from the pressure sensing component 2 along the first direction A. The movement direction and movement path of the workbench 3 relative to the base 1 are limited by the cooperation between the slider 62 and the slide rail 61 to prevent the workbench 3 from shaking; the base 1 and the slide rail 61 are relatively fixed, and the elastic member 63 acts on the slider 62, and the slider 62 transmits the force of the elastic member 63 to the workbench 3, so that the workbench 3 can be reset or hover relative to the base 1. It is understood that in some embodiments, the slide rail 61 is separately provided and fixedly connected to the base 1, or the slide rail 61 is integrally provided with the base 1. It is understood that in some embodiments, before the working assembly 4 operates on the workpiece, by reciprocating the slider 62 along the first direction A, if there is any jamming, it is necessary to check whether there is an assembly problem, or to use a lubricant to make the slider 62 slide more smoothly, to ensure that the slider 62 can slide smoothly and without jamming along the slide rail 61, so as to avoid affecting the accurate sensing of the pressure of the pressure sensing assembly 2 on the worktable 3. Referring to Figures 1 to 3, in some embodiments, the slider 62 is provided with a workbench mounting portion 621 and an elastic member mounting hole 622. The workbench 3 is detachably connected to the workbench mounting portion 621 to be fixed to the slider 62. The elastic member mounting hole 622 is arranged toward the base 1, and the elastic member 63 is arranged in the elastic member mounting hole 622, which reduces the length of the elastic component 6 along the first direction A, makes the overall structure more compact, and protects the elastic member 63 from interference from the external environment. In some embodiments, the slide rail 61 is provided with a limit portion 611, so that when the slider 62 moves along the first direction A away from the pressure sensing component 2, it is stopped by the limit portion 611, thereby preventing the elastic member 63 from applying excessive force to the slider 62 and causing the slider 62 to detach from the slide rail 61. Referring to Figures 1 and 3 , in some embodiments, the workbench 3 is roughly square in shape, with the four corresponding corners of the workbench 3 movably connected to the base 1 via elastic components 6 . The elastic components 63 are springs, and UH10-35 springs can be used. The initial force of each spring is ensured to be 2 kgf ± 0.3 kgf, ensuring that the flatness of the four corners of the workbench 3 is within 0.05 mm and preventing the workbench 3 from shaking. By using a push-pull force gauge to push the workbench mounting portion 621 of the slider 62, a force of 2 kgf ± 0.3 kgf is measured at the moment the slider 62 just releases the stop 611. This ensures that the initial force of the spring is 2 kgf ± 0.3 kgf. If this does not meet the requirements, the spring is replaced or trimmed until the required force is achieved. It is understood that in other embodiments, the initial force of the spring may need to be adaptively adjusted for different workpieces, different operating requirements, or different operating methods, rather than being limited to the above range, to prevent the operating component 4 from applying excessive pressure to the workpiece. Referring to Figures 1, 2, and 4, in some embodiments, the pressure sensing assembly 2 includes a pressure sensor 21, a sensor mounting block 22, and a sensor mounting base 23. The pressure sensor 21 is mounted on the sensor mounting block 22. The sensor mounting block 22 is mounted on the sensor mounting base 23 and can be adjusted relative to the sensor mounting base 23 along a first direction A. The sensor mounting base 23 is mounted on the base 1. By adjusting the position of the sensor mounting block 22 on the sensor mounting base 23, the distance of the gap 31 between the pressure sensor 21 and the workbench 3 can be adjusted. Referring to Figures 1, 2 and 4, in some embodiments, the operating pressure protection system 100 further includes a first gauge 81, which is used to adjust the gap 31 between the pressure sensing component 2 and the workbench 3. After confirming the initial force value of the elastic member 63, the first gauge 81 is placed between the sensor mounting block 22 and the base 1, and the position of the sensor mounting block 22 on the sensor fixing seat 23 is quickly positioned by the height of the first gauge 81. By preparing a plurality of first gauges 81 of different heights, different positions of the sensor mounting block 22 can be quickly positioned. In some embodiments, the size of the gap 31 between the pressure sensing component 2 and the workbench 3 is adjusted by adjusting the initial force value of the elastic member 63 and the position of the sensor mounting block 22 relative to the sensor fixing seat 23. In some embodiments, the pressure sensor 21 must be zeroed and calibrated before any work is performed on the workpiece. This is done by placing a force gauge directly against the pressure sensor 21. A calibration coefficient is then applied to align the pressure value displayed by the pressure sensor 21 with the value displayed by the force gauge. To ensure accurate zeroing and calibration of the pressure sensor 21, the pressure sensor 21 must undergo these zeroing and calibration steps 50 times. Referring to FIG. 2 , in some embodiments, the operating pressure protection system 100 includes a detection element (not shown) for detecting the status of the workbench 3 . The detection element is electrically connected to the drive assembly 5 . When the detection element detects that the workbench 3 allows the operating assembly 4 to operate, the drive assembly 5 can drive the operating assembly 4 in a first direction A away from the workbench 3 . When the detection element detects that the workbench 3 does not allow the operating assembly 4 to operate, the drive assembly 5 cannot drive the operating assembly 4 in the first direction A away from the workbench 3 . By determining whether the operating assembly 4 can operate on the workpiece, the detection element prevents the drive assembly 5 from mistakenly driving the working assembly 4 when the excessive pressure sensed by the pressure sensing element 2 is not due to excessive pressure from the working assembly 4 on the workpiece. This prevents the operating pressure protection system 100 from being affected by interference factors, thereby ensuring that the operating pressure protection system 100 can stably limit and protect the workpiece's operating pressure. For example, this prevents the pressure generated by the pressure sensing element 2 securing the workpiece to the workbench 3 from being interpreted as the operating pressure of the working assembly 4 on the workpiece. Referring to Figures 1 and 2, in some embodiments, the operating pressure protection system 100 further includes a fixing member 32 and a locking member 33. The fixing member 32 is rotatably connected to the workbench 3. The locking member 33 is provided on the workbench 3. The locking member 33 can lock the fixing member 32 so that the workbench 3 allows the operating component 4 to operate. The fixing member 32 fixes the workpiece on the workbench 3 under the locking of the locking member 33. The operating component 4 can operate on the workpiece only after the workbench 3 fixes the workpiece, so that after the locking member 33 locks the fixing member 32, the driving component 5 decides whether to drive the operating component 4 to move according to the pressure value sensed by the pressure sensing component 2. It can be understood that in some embodiments, the detection member is provided at the locking connection between the fixing member 32 and the locking member 33, and the fixing member 32 can be a cover plate. Referring to Figures 1 and 2, in some embodiments, the working assembly 4 includes a working piece 41 and a working frame 42. The working piece 41 is mounted on the working frame 42. The working piece 41 is used to perform operations on a workpiece on the workbench 3. The working frame 42 is slidably connected to the base 1 along a first direction A. The driving assembly 5 is capable of driving the working frame 42 to move away from the workbench 3 along the first direction A, thereby driving the working piece 41 away from the workbench 3 along the first direction A. The working piece 41 performs operations on the workbench 3, so that the pressure sensing assembly 2 senses the pressure of the workbench 3 to determine the operating pressure applied to the workpiece. The driving assembly 5 drives the working frame 42 to move and drives the working piece 41 away from the workpiece, separating the portion of the working assembly 4 where the operations are performed from the portion driven by the driving assembly 5, so that the working piece 4 is not affected by the structure of the driving assembly 5 when performing operations on the workpiece. It is understood that in some embodiments, the working piece 41 is an electric screwdriver used to perform screwing operations on the workpiece. In other embodiments, the working piece 41 can perform other working processes such as welding, patching, and gluing. Referring to Figures 1 and 2 , in some embodiments, the operating pressure protection system 100 further includes a support rod 11. The support rod 11 is mounted on the base 1 and extends in a first direction A. The work frame 42 includes a plurality of connecting rods 421 that are rotatably connected in sequence. The first of the connecting rods 421 is mounted on the support rod 11, and the last is connected to the workpiece 41. The first connecting rod 421 is mounted on the support rod 11, allowing the work frame 42 to both slide along the support rod 11 and rotate about it. The rotational relationship between the connecting rods 421 allows the workpiece 41 to move not only in the first direction A but also in a direction perpendicular to the first direction A, facilitating movement of the workpiece 41 to work on a workpiece. Furthermore, the mounting of the connecting rods 421 on the support rod 11 and the rotatable connection between the connecting rods 421 allow the workpiece 41 to move freely along a plane perpendicular to the first direction A without being fixed. It is understood that in some embodiments, the axial direction of the rotating shafts between the plurality of connecting rods 421 intersects at least with the first direction A. To achieve a better driving effect on the workpiece 41 when the drive assembly 5 drives the work frame 42 to move, the axial direction of the rotating shafts between the plurality of connecting rods 421 is perpendicular to the first direction A, that is, parallel to the horizontal direction. It is understood that in some embodiments, the support rod 11 and the base 1 are separately provided and fixedly connected, or the support rod 11 and the base 1 are integrally provided. Referring to Figures 2 and 5, in some embodiments, the drive assembly 5 includes a drive member 51 and a push block 52. The push block 52 is slidably connected to the support rod 11. The drive member 51 drives the push block 52 to slide along the first direction A to push the work frame 42 away from the workbench 3. By pushing the work assembly 4 to move, the drive assembly 5 and the work assembly 4 do not need to be connected to each other and can still drive the work assembly 4 to move. Therefore, the movement of the work assembly 4 in the first direction A during normal operation on the workpiece is not affected by the drive assembly 5. It is understood that in some embodiments, the drive member 51 is fixedly connected to the support rod 11. To ensure the stable movement of the push block 52, the push block 52 is fixedly connected to the output end of the drive member 51. The drive member 51 is a pneumatic cylinder with rapid action and quick response, which can quickly drive the workpiece 41 away from the workpiece to avoid damage to the workpiece. In other embodiments, the drive member 51 is a motor or hydraulic cylinder or other mechanism capable of achieving a driving action. In some embodiments, the driving assembly 5 further includes a protective shell 53 . The protective shell 53 is disposed on the outer periphery of the push block 52 to prevent the push block 52 from pinching the hand when it moves to abut against the connecting rod 421 . Referring to Figures 1 and 2, in some embodiments, the support rod 11 is connected to a limiting member 111, and the limiting member 111 is located on one side of the working frame 42 away from the driving component 5 to stop the working frame 42 from continuing to move. When the driving component 5 drives the working frame 42 to move away from the workbench 3 along the first direction A, in order to avoid the working frame 42 moving too far, if one end of the working frame 42 connected to the working piece 41 is not driven to move a similar distance in time, it is easy to cause damage to the connecting rod 421 of the working frame 42. 2 and 5 , in some embodiments, the operating pressure protection system 100 further includes a second gauge 82, which is used to adjust the position of the drive assembly 5 and the work frame 42 on the support rod 11. The second gauge 82 includes a gauge body 821 and a gauge head 822. One end of the gauge body 821 is placed on the base 1, and the gauge head 822 is provided at the other end of the gauge body 821. The push block 52 and the connecting rod 421 are respectively clamped on opposite sides of the gauge head 822 along the first direction A and fit together. At this time, the cylinder is in a retracted state, which can ensure that the distance between the push block 52 and the connecting rod 421 is 4 mm ± 1 mm, so that the work piece 41 can be moved close to the workbench 3 in the first direction A for screw locking. The gauge body 821 can directly position the height of the work piece 41 to a height that is convenient for the operator to operate on the workpiece by positioning the work frame 42. It is understandable that in other embodiments, for different workpieces, or different operating requirements, or different operating methods, the distance between the push block 52 and the connecting rod 421 needs to be adaptively changed, and is not limited to the above range, so as to avoid excessive pressure exerted by the operating component 4 on the workpiece. Referring to Figures 1, 2 and 6, in some embodiments, the operating pressure protection system 100 also includes a processor 7, which includes a control module 71, a display module 72, an alarm module 73 and a recording module 74. The control module 71 is electrically connected to the pressure sensing component 2 to receive the pressure value sensed by the pressure sensing component 2, the control module 71 is electrically connected to the driving component 5 to control the driving action of the driving component 5 on the operating component 4, the control module 71 is electrically connected to the alarm module 73 to control the alarm module 73 to alarm, and the control module 71 is electrically connected to the recording module 74 to record the situation where the sensed pressure value exceeds the set value. The control module 71 determines whether the operating pressure on the workpiece is too high, and then decides whether to let the driving component 5 drive the operating component 4 away from the workpiece; the control module 71 can control the display module 72 to display the pressure value applied by the operating component 4 when operating on the workpiece; the control module 71 can control the alarm module 73 to alarm when the operating pressure on the workpiece is too high, so as to warn the operator; the control module 71 can control the recording module 74 to record the situation where the operating pressure on the workpiece is too high, so as to realize the monitoring of the workpiece operation process. 1 , 2 and 6 , it can be understood that, in some embodiments, the control module 71 is a central processing unit (CPU) 7, a microprocessor 7, a computer or other data processing device; the processor 7 is provided with an air pipe joint 75 connected to the cylinder to control the driving action of the driving component 5; the processor 7 is provided with a pressure terminal 76 connected to the pressure sensing component 2 to receive the pressure value sensed by the pressure sensing component 2; the processor 7 is connected to the working piece 41, and when the working frame 42 is driven by the driving component 5 and moves away from the workbench 3 along the first direction A, the control module 71 controls the working piece 41 to stop working, for example, stopping the electric screwdriver. The display module 72 is a touch display screen, and the alarm of the alarm module 73 is canceled by manually touching the alarm cancel interface of the touch display screen; the alarm module 73 is at least one of a sound alarm, a light alarm and a communication alarm; the recording module 74 can record the number of operations in which the operating component 4 applies excessive pressure to the workpiece, the excessive pressure value and the operator, and the recording module 74 can upload the above data and store it for at least 1 month. The processor 7 is provided with a real-name terminal 77 connected to the real-name module to record who the operator is. Referring to Figures 4-6 , in some embodiments, the value displayed by the display module 72 represents the pressure value of the workpiece exerted by the working assembly 4 . The value displayed by the display module 72 and the pressure value sensed by the pressure sensing assembly 2 must be offset by the gross weight of the worktable 3 and the elastic force of the elastic assembly 6 . The control module 71 must set a compensation value, which is added to the pressure value sensed by the pressure sensing assembly 2 to ensure that the value displayed by the display module 72 represents the pressure value exerted by the working assembly 4 on the workpiece. It is understood that in some embodiments, taking the maximum pressing force applied to a workpiece when screwing a screw cannot exceed 3 kgf as an example, a push-pull force gauge is used to push the worktable 3 until the push-pull force gauge displays 3 kgf, and the display value of the display module 72 is observed. If the display module 72 does not display a value, it indicates that the gap 31 between the pressure sensing component 2 and the worktable 3 is not correctly adjusted, and the initial force value of the spring is not correctly adjusted, and needs to be adjusted again. If the display module 72 displays a value, it is recorded as F1, and then a compensation value of 3 kgf is calculated as 3-F1. The calculated compensation value is input into the PLC to complete the compensation setting, so that the display value displayed on the display module 72 is the pressure value of the working component 4 at the time of the workpiece. It is understood that in other embodiments, for different workpieces, different operating requirements, or different operating methods, the maximum pressing force applied to the workpiece when setting the compensation value needs to be adaptively changed, not limited to the above range, to avoid excessive pressure applied by the working component 4 on the workpiece. Referring to Figures 1 and 2 , in some embodiments, the operating pressure protection system 100 further includes a protective block 12 . Protective block 12 is disposed on base 1 and extends at least partially to a side of the worktable 3 that is distal to the pressure sensing assembly 2 in the first direction A. Protective block 12 prevents an operator from accidentally touching the worktable 3 while working on a workpiece, thereby preventing the drive assembly 5 from driving the operating assembly 4 away from the workpiece. Furthermore, the operator can support their arm on protective block 12 while controlling the operating assembly 4, thus saving effort. Referring to Figures 1 and 2 , in some embodiments, the operating pressure protection system 100 further includes a material preparation rack 13. The material preparation rack 13 is used to store materials, such as screws, for the working assembly 4 to work on the workpiece. The material preparation rack 13 is connected to the base 1 and is substantially flush with the worktable 3. This allows the materials to be stored flush with the workpiece when stored on the rack, facilitating smooth material removal by the working assembly 41. The working assembly 41 does not need to move in the first direction A during the process of removing materials from the material preparation rack 13 and placing them on the workpiece for operation, thereby avoiding being restricted by the drive assembly 5. In this application, the operating assembly 4 operates on the workpiece carried by the worktable 3. The worktable 3 is configured to be movable relative to the base 1, so that when the operating assembly 4 applies pressure to the workpiece, it can push the worktable 3 to move. The pressure is transmitted through the worktable 3, and the pressure applied by the operating assembly 4 on the workpiece is converted into pressure applied by the worktable 3 on the pressure sensing assembly 2. Therefore, by comparing the pressure value sensed by the pressure sensing assembly 2 with the set value, it is determined whether the pressure applied by the operating assembly 4 on the workpiece is excessive. When the pressure applied by the operating assembly 4 on the workpiece reaches the upper limit, the driving assembly 5 drives the operating assembly 4 away from the worktable 3, reducing the pressure applied to the workpiece, thereby preventing the operating assembly 4 from applying excessive pressure on the workpiece and causing damage to the workpiece.
