[0002] In this ever-changing era, there are more and more categories of electronic products, and the internal components of complete products are also developing towards miniaturization and diversification. After some ordinary components are assembled, some components may not be firmly assembled, so it is necessary to ensure the firm installation of the components through a pressure maintaining action. Due to the limited internal space of electronic products, it is very difficult to maintain pressure on multiple components simultaneously in a small space, which brings us great trouble. If we follow the normal operation method, we will organize multiple machines, but this will result in high costs and low cost performance.

[0033] Referring to Figures 1-3 , an embodiment of the present utility model provides a pressure maintaining device 100, including a mounting frame 10, a floating assembly 20 and an elastic pressure maintaining assembly 30. Among them, a stroke driving device 11 is provided on the mounting frame 10; the floating assembly 20 is slidably mounted on the mounting frame 10 and connected to the stroke driving device 11, and is adapted to reciprocate on the mounting frame 10 under the action of the stroke driving device 11; the elastic pressure maintaining assembly 30 is detachably connected to the floating assembly 20, and a plurality of elastic pressure heads 32 corresponding one-to-one to a plurality of pressure maintaining positions of the product are provided on the elastic pressure maintaining assembly 30. The elastic pressure maintaining assembly 30 is adapted to press the pressure maintaining positions of the product through the plurality of elastic pressure heads 32 under the drive of the stroke driving device 11 to perform a pressure maintaining process on it.

[0034] Specifically, the stroke driving device 11 is a power mechanism with stroke driving, which has displacement driving and can apply a force to a structure connected thereto based on the displacement driving. In this embodiment, it is used to apply a force to the elastic pressure maintaining assembly 30 through the floating assembly 20.

[0035] The floating assembly 20 is slidably mounted on the mounting frame 10 and connected to the stroke driving device 11, so that it can move in a defined direction, thereby transmitting the drive of the stroke driving device 11 to the elastic pressure maintaining assembly 30.

[0036] The elastic pressure-maintaining component 30 has a plurality of elastic pressure heads 32, and is detachably connected to the floating component 20. In this way, not only can the elastic pressure-maintaining component 30 of corresponding specifications and sizes be replaced according to the size of the pressure-maintaining space, so that it can be suitable for local space or small space, but also the corresponding elastic pressure-maintaining component 30 can be replaced according to the product to be pressure-maintained, so that the plurality of elastic pressure heads 32 on the elastic pressure-maintaining component 32 correspond to the pressure-maintaining positions on the product to be pressure-maintained, so that pressure can be maintained at multiple pressure-maintaining positions of the product at the same time. At the same time, by setting the elastic pressure head 32 to achieve flexible contact, the alarm caused by hard contact is reduced. In addition, the elastic pressure head 32 can be adjusted so that different elastic pressure heads 32 in the elastic pressure-maintaining component 30 have different holding pressures when pre-pressed at a suitable distance, so as to adapt to different pressure-maintaining positions of the product.

[0037] The pressure-maintaining device 100 provided by the embodiment of the utility model is provided with an elastic pressure-maintaining component 30 that can be used in a local space or a small space, and a plurality of elastic pressure heads 32 corresponding to the pressure-maintaining positions are provided on the elastic pressure-maintaining component 30, so that the pressure-maintaining points can be set according to the pressure-maintaining requirements of the product, thereby realizing multi-point pressure-maintaining in the local space (or small space); at the same time, the elastic pressure-maintaining component 30 can realize flexible contact with the product through the elastic pressure head 32, reducing the alarm caused by hard contact, so the structure is simple and the practicability is wide; in addition, the elastic pressure head at the corresponding position can be adjusted according to the pressure demand of the pressure-maintaining position, so that when the elastic pressure-maintaining component moves to the preset position, the pressure-maintaining pressure of the elastic pressure heads at different pressure-maintaining positions is consistent with the pressure-maintaining pressure required by the corresponding pressure-maintaining position, so that it is ensured that the pressure-maintaining work will not cause problems such as pressure alarms, and the downtime rate is reduced. Based on the above structure, not only the assembly firmness of multi-component electronic products is guaranteed, but also the assembly cost is reduced, and the structure and control method of the above pressure-maintaining device 100 are simple and the practicability is wide.

[0038] In one embodiment, the elastic pressure-maintaining assembly 30 includes a mounting seat 31 , and the elastic pressure head 32 includes an elastic member 33 and a pressure-applying portion 34 . The elastic member 33 is installed in the mounting seat 31 , and one end of the elastic member 33 facing away from the floating assembly 20 is connected to the pressure-applying portion 34 .

[0039] Specifically, the elastic member 33 is vertically arranged in the mounting seat 31, and one end close to the floating component 20 is connected to the mounting seat 31, and the other end is connected to the pressure-applying portion 34, so that when the mounting seat 31 moves downward, it can drive the elastic member 33 and the pressure-applying portion 34 to move downward until the pressure-applying portion 34 presses the product, and then as the mounting seat 31 continues to move downward until the elastic member 33 is compressed to a preset length, the elastic member 33 compressed to the preset length has a preset elastic force, which is transmitted to the product through the pressure-applying portion 34, and can provide a stable pressure-maintaining force for the product.

[0040] Optionally, the elastic member 33 is a spring or a disc spring, preferably a spring.

[0041] In one embodiment, the mounting seat 31 is provided with a mounting hole 311, and a plunger 312 and a guide rod 313 disposed in the mounting hole 311. The elastic member 33 is disposed between the plunger 312 and the guide rod 313 and is connected to the pressing portion 34 through the guide rod 313. In this way, the elastic member 33 can be fixed in the mounting hole 311 through the plunger 312 and the guide rod 313, thereby realizing the connection between the elastic member 33 and the mounting seat 31. At the same time, the connection between the elastic member 33 and the pressing portion 34 is also realized through the guide rod 313. In addition, the above structure can also realize the replacement of the elastic member 33, and thus the elastic member 33 with a corresponding elastic coefficient can be replaced according to the needs of the pressing force.

[0042] In one embodiment, the mounting hole 311 includes a small-diameter section and a large-diameter section connected to each other. The small-diameter section is formed with a necking near the large-diameter section; the guide rod 313 includes a head end and a guiding end. The head end is located in the small-diameter section and is connected to the elastic member 33, and the guiding end is inserted into the large-diameter section from the necking. In this way, the limitation of the guide rod 313 can be realized through locking, so that the guide rod 313 can move axially along the mounting hole 311 within a preset range, and thus the elastic force of the elastic member 33 is transmitted to the pressing portion 34.

[0043] In one embodiment, the mounting seat 31 further includes a fixture bushing 314 having a central hole. The fixture bushing 314 is installed at the large-diameter end of the mounting hole 311, and the guiding end of the guide rod 313 passes through the central hole to be connected to the pressing portion 34. By providing the fixture bushing 314, limit and guidance can be provided for the guide rod 313, and the interference between the guide rod 313 and the mounting hole 311 is also reduced, making the movement of the guide rod 313 smoother.

[0044] In one embodiment, the mounting seat 31 is formed with a central portion and a mounting portion disposed on the outer periphery of the central portion. The side surface of the mounting portion adjacent to the floating assembly 20 protrudes from the central portion, and the side surface of the mounting portion away from the floating assembly 20 is in the same plane as the central portion. In this way, by providing the mounting portion with a certain thickness, the length of the mounting hole 311 can be increased, and thus the spring can be buried in the mounting seat 31. At the same time, by providing the central portion with a reduced thickness, the weight of the mounting seat 31 can be reduced.

[0045] In one embodiment, the pressing portion 34 includes a fixed member 341 and a movable member 342. The fixed member 341 is provided with a guide rail and is installed on the side surface of the mounting seat 31 away from the stroke driving device 11. The movable member 342 is slidably installed on the guide rail and is connected to the guide rod 313. In this way, the moving direction of the movable member 342 can be limited by the fixed member 341, thereby preventing the pressing portion 34 from shifting during the pressing process, and thus improving the alignment accuracy with the product pressure maintaining position.

[0046] In one embodiment, the movable member 342 is provided with a stepped hole and a connector adapted to the stepped hole. The small end of the connector protrudes from the lower surface of the movable member 342, and the large end of the connector is connected to the guide rod 313. This facilitates the connection between the pressing portion 34 and the guide rod 313.

[0047] In one embodiment, the mounting frame 10 includes a top plate and a plurality of columns connected to the top plate. The floating assembly 20 includes a floating plate 21 and a guide sleeve 22 connected to the outer periphery of the floating plate 21. The guide sleeve 22 is slidably sleeved on the column.

[0048] Specifically, in the mounting frame 10, the top plate is a rectangular plate, and the number of columns is 4, which are respectively connected to the four corners of the top plate. The stroke driving device 11 is an electric cylinder or a pneumatic cylinder, preferably an electric cylinder, which is installed above the top plate, and the piston rod of the electric cylinder passes through the top plate and extends below the top plate.

[0049] In the floating assembly 20, the floating plate 21 is a rectangular plate, and the guide sleeve 22 is a hollow sleeve, which is arranged at the four corners of the floating plate 21. The floating assembly 20 is slidably mounted on the mounting frame 10 by sleeving the hollow sleeve on the column, and is connected to the piston rod of the electric cylinder through the floating plate 21. In this way, the floating assembly 20 can move along the axial direction of the column under the drive of the electric cylinder, and the floating assembly 20 drives the elastic pressure maintaining assembly 30 to move along the axial direction of the column. When the elastic pressure maintaining assembly 30 moves downward, it can press the pressure maintaining position of the product and apply a force to it for pressure maintaining.

[0050] In one embodiment, the elastic pressure maintaining assembly 30 further includes a connecting rod 36 and a connecting plate 35. The connecting plate 35 is installed on the top plate. There are multiple connecting rods 36. One end of the multiple connecting rods 36 is connected to the connecting plate 35, and the other end is connected to the mounting seat 31.

[0051] Specifically, a plurality of studs are provided on the connecting plate 35, and each stud is detachably connected to the floating plate 21 by a thread. In this way, the elastic pressure maintaining assembly 30 can be replaced according to the shape of the product and the pressure maintaining position, so as to realize the corresponding setting of the position of the elastic pressing head 32 and the pressure maintaining position of the product.

[0052] The connecting plate 35 is connected to the mounting seat 31 through a plurality of connecting rods 36. On the one hand, this can improve the connection strength, and on the other hand, it can ensure the balance of the mounting seat 31, so that the acting forces of the elastic pressing heads 32 are consistent.

[0053] The specific working process of the above pressure maintaining device 100 is as follows:

[0054] Before pressure maintaining, select a suitable elastic pressure maintaining assembly 30 according to the structure of the product, calculate the pressure required for a single pressing portion 34 in the elastic pressure maintaining assembly 30, select a suitable type of spring, and adjust the preloading state of the spring so that the pressing portion 34 reaches the specified pressure when it reaches the preset position;

[0055] During operation, the electric cylinder moves downward, and drives the elastic pressure-holding assembly 30 to slowly approach and contact the product through the floating assembly 20, and the spring in the elastic pressure head 32 starts to compress;

[0056] The electric cylinder drives the elastic pressure-holding assembly 30 to continue pressing down until it reaches the preset position. At this time, when the pressure at all the pressure-holding positions of the product reaches the specified pressure, maintain the current state to start pressure-holding until the pressure-holding structure.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
