Description

Technical Field

[0001] The present disclosure relates to the field of electronic device assembly, and particularly to a pressure maintaining device. Background Art

[0002] In the assembly process of products in the information appliance industry integrating computers, communications, and consumer electronics (abbreviated as 3C), it is necessary to paste two components and then perform a packaging operation. An adhesive is provided on one of the components, and the two components are connected through the adhesive. Generally, after the two components are bonded, it is also necessary to apply continuous pressure for pressure maintaining to ensure the sealing and waterproof performance between the two components.

[0003] In the related art, in order to enable two components to be firmly attached together, a pressure maintaining device is usually used for pressure maintaining operations. Generally, the pressure maintaining mechanism drives a pressure block provided thereon to move up and down through a clamp movably connected to a platform, so as to press on the platform where the components to be pressure maintained are placed, thereby realizing the bonding and pressure maintaining of the two components. However, due to the single-arm movement of the traditional pressure maintaining device, the working space between it and the platform is limited, which is not conducive to the operation of the clamping tweezers or vacuum suction pen for picking and placing components, resulting in a long duration of the entire pressure maintaining operation and low pressure maintaining operation efficiency.

[0013] In a possible implementation, the rotating member includes a rotating shaft and a bearing sleeved on the rotating shaft, and the rotating shaft is fixedly connected to the pressing arm.

[0014] In a possible implementation, there are two support arms, and the two support arms are spaced apart. There are two driving arms, and the two driving arms are respectively arranged corresponding to the two support arms. The pressing block assembly includes two pressing arms, a carrier, and a pressing block. The two pressing arms are respectively movably connected to the two support arms and the two driving arms. The carrier is connected between the two pressing arms. The pressing block is correspondingly disposed on the side of the carrier facing the support platform.

[0015] In a possible implementation, the pressing block assembly further includes a limiting member, and the limiting member is disposed on the side of the carrier facing the support platform. The side of the limiting member away from the carrier is flush with the side of the pressing block away from the carrier.

[0016] In a possible implementation, the pressing block assembly further includes a plurality of first reinforcing ribs, and the first reinforcing ribs are disposed between the two pressing arms.

[0017] In a possible implementation, there are two support arms. The two support arms are arranged at intervals. The driving assembly includes two driving arms and a second reinforcing rib. The second reinforcing rib is connected between the two driving arms.

[0018] In a possible implementation, the support platform includes a first carrier plate, a second carrier plate and an elastic member. The first carrier plate includes an operation area and a fixed area located on one side of the operation area. The second carrier plate is arranged in the operation area. The elastic member is connected between the second carrier plate and the first carrier plate. The accommodation groove is arranged on the side of the second carrier plate away from the first carrier plate.

[0019] In a possible implementation, the pressure maintaining device further includes a pressure sensor, a timer, a buzzer and a control member. The pressure sensor, the timer and the buzzer are all electrically connected to the control member;

The pressing mechanism is configured to include at least a combined component of a driving component and a pressing block component. The pressing block component is a linkage of the driving component. During the process of the driving component rotating from the initial position to the pressure-holding position, the pressing block component is driven to rotate from the initial position to the pressure-holding position. Thus, during the process of the pressing block component being linked, the pressing block component has two movement trajectories: one is that the pressing block component rotates from the initial position to be parallel to the support platform, and this first movement trajectory is in an arc form; the other is that the pressing block component moves linearly from the position parallel to the support platform to the pressure-holding position close to the support platform and presses the workpiece to be pressure-held, and this second movement trajectory is in a straight line form. In this way, by optimizing the linkage mode of the driving component and the pressing block component, the use mechanism of the pressure-holding device is optimized, and further the simplicity of use of the pressure-holding device and the efficiency of the pressure-holding operation are improved. In addition, in the above use mechanism, the situation that the traditional pressure-holding device has limited pressure-holding operation space between the clamp and the platform because the clamp only drives the pressing block to move up and down, and thus it is inconvenient for operators to operate in a narrow operation space is avoided, effectively increasing the pressure-holding operation space of the pressure-holding device, reducing the time-consuming of operators when taking and placing products, and further improving the efficiency of the pressure-holding operation.

[0046] See Figures 1 to 6 , this embodiment of the present disclosure provides a pressure maintaining device, including: a support platform 100 and a pressing mechanism.

[0047] The support platform 100 includes an operation area α and a fixed area β located on one side of the operation area α. The operation area α is provided with a receiving groove 101 for placing the workpiece to be pressure-maintained, and the fixed area β is provided with a support arm 110;

[0048] The pressing mechanism is movably connected to the support arm 110. The pressing mechanism includes a driving component 200 and a pressing block component 300 that are connected to each other. Among them, during the process of the driving component 200 rotating from the initial position to the pressure maintaining position, the pressing block component 300 is driven to rotate from the initial position to be parallel to the support platform 100, and then continues to move linearly closer to the support platform 100 and press the workpiece to be pressure-maintained.

[0049] In this embodiment, by optimizing the specific structure of the pressure maintaining device, the difficulty of using the pressure maintaining device by operators is reduced, thereby improving the pressure maintaining efficiency of the pressure maintaining device.

[0050] Specifically, the pressure maintaining device is configured to include at least a combined component of a support platform 100 and a pressing mechanism. The support platform 100 is used to provide a supporting force for the pressing mechanism, and at the same time is also used to provide a receiving position for the workpiece to be pressure-maintained. The pressing mechanism is used to cooperate with the support platform 100 to provide continuous pressure to the workpiece to be pressure-maintained, so that the two products to be pressure-maintained can be well pressure-maintained.

[0051] Further, the support platform 100 is provided with an operation area α and a fixed area β. The operation area α is provided with a receiving groove 101 for placing the workpiece to be pressure-maintained, and the fixed area β is provided with a support arm 110. The pressing mechanism is movably connected to the support arm 110. At the same time, the pressing mechanism is configured to include at least a combined component of a driving component 200 and a pressing block component 300. The pressing block component 300 is a linkage component of the driving component 200. During the process of the driving component 200 rotating from the initial position to the pressure maintaining position, the pressing block component 300 is driven to rotate from the initial position to the pressure maintaining position.

[0052] As described above, the driving assembly 200 always maintains a rotating motion trajectory. During the process of being linked, the pressing block assembly 300 has two motion trajectories: First, the pressing block assembly 300 rotates from the initial position to the first motion trajectory parallel to the support platform 100, and this first motion trajectory is in an arc form; Second, the pressing block assembly 300 moves linearly from the position parallel to the support platform 100 to the second motion trajectory of the pressure-holding position close to the support platform 100 and pressing the workpiece to be pressure-held, and this second motion trajectory is in a linear form. In this way, by optimizing the linkage mode of the driving assembly 200 and the pressing block assembly 300, the use mechanism of the pressure-holding device is optimized, thereby improving the simplicity of use of the pressure-holding device and the efficiency of the pressure-holding operation.

[0053] In addition, in the above-mentioned use mechanism, the situation that the traditional pressure-holding device has limited pressure-holding operation space between the clamp and the platform because the clamp only drives the pressing block to move up and down, and thus it is inconvenient for the operator to operate in a narrow operation space is avoided. The pressure-holding operation space of the pressure-holding device is effectively increased, the time-consuming for the operator to pick and place products is reduced, and the efficiency of the pressure-holding operation is further improved.

[0054] See Figures 1 to 6 , in a possible implementation manner, the driving assembly 200 includes a driving arm 210, the pressing block assembly 300 includes a pressing arm 310, a first groove 111 is provided on the support arm 110, a second groove 211 is provided on the driving arm 210, and a rotating member 311 is provided on the pressing arm 310. The rotating member 311 sequentially penetrates through the first groove 111 and the second groove 211, so that the pressing arm 310 is movably connected to the support arm 110 and the driving arm 210 at the same time.

[0055] In this embodiment, the connection mode of the driving assembly 200 and the pressing block assembly 300 is optimized. Specifically, the driving assembly 200 is configured as a member including at least the driving arm 210, and at the same time the pressing block assembly 300 is configured as a member including at least the pressing arm 310. A rotating member 311 is provided on the pressing arm 310, a first groove 111 is provided on the support arm 110, and a second groove 211 is provided on the driving arm 210. In this way, the rotating member 311 sequentially passes through the first groove 111 and the second groove 211 to realize the movable connection of the pressing arm 310, the support arm 110 and the driving arm 210.

[0056] Specifically, the rotating member 311 can move in the first groove 111 and the second groove 211 simultaneously, so as to realize the relative movement between the pressing arm 310 and the supporting arm 110 and the driving arm 210. During the process of the driving arm 210 rotating from the initial position to the pressure-holding position, the rotating member 311 is driven to rotate from the initial position to be parallel to the supporting platform 100. At this time, the rotating member 311 moves in the first groove 111 and the second groove 211 simultaneously, and the movement stroke of the rotating member 311 in the first groove 111 is greater than that in the second groove 211. The rotation stroke of the rotating member 311 in the first groove 111 is the first movement trajectory. During the process of the driving arm 210 rotating from the initial position to the pressure-holding position, the rotating member 311 moves linearly from the position parallel to the supporting platform 100 to the pressure-holding position close to the supporting platform 100 and pressing the workpiece to be pressure-held. At this time, the rotating member 311 moves in the first groove 111 and the second groove 211 simultaneously, and the movement stroke of the rotating member 311 in the first groove 111 is less than that in the second groove 211. The movement stroke of the rotating member 311 in the first groove 111 is the second movement trajectory.

[0057] See Figure 4 , in a possible implementation manner, the first groove 111 includes a first sub-groove 1111 and a second sub-groove 1112 which are arranged at intervals, and the second sub-groove 1112 is arranged close to the supporting platform 100. The rotating member 311 is provided with two, and the two rotating members 311 are arranged at intervals on the pressing arm 310. One of the rotating members 311 penetrates through the first sub-groove 1111 and the second groove 211, and the other rotating member 311 penetrates through the second sub-groove 1112.

[0058] In this embodiment, the specific form of the first groove 111 on the supporting arm 110 is optimized. Specifically, the first groove 111 is configured as a combined groove form including at least the first sub-groove 1111 and the second sub-groove 1112. At the same time, two rotating members 311 are configured to cooperate with the first sub-groove 1111 and the second sub-groove 1112 respectively, so as to realize the arc rotation and linear movement of the pressing arm 310 simultaneously.

[0059] In a specific example, the second sub-groove 1112 has a certain length, and the second sub-groove 1112 extends in the direction close to the supporting platform 100. In this way, it cooperates with the first sub-groove 1111 to realize the linear movement of the rotating member 311 along the direction close to or away from the supporting platform 100.

[0060] See Figure 2, in a possible implementation, the first sub-groove 1111 includes an arc-segment groove 1101 and a straight-segment groove 1102 communicating with the arc-segment groove 1101, and the extension line of the straight-segment groove 1102 and the rotation center of the arc-segment groove 1101 are on the same straight line perpendicular to the support platform 100; the second sub-groove 1112 is arranged parallel to the straight-segment groove 1102.

[0061] In this embodiment, the shape of the first sub-groove 1111 is optimized to optimize the relative positional relationship between the first sub-groove 1111 and the second sub-groove 1112. Specifically, the first sub-groove 1111 is configured as a bent groove structure including an arc-segment groove 1101 and a straight-segment groove 1102. The movement of the rotating member 311 in the arc-segment groove 1101 corresponds to the first movement trajectory of the pressing arm 310, and the movement of the rotating member 311 in the straight-segment groove 1102 corresponds to the second movement trajectory of the pressing arm 310.

[0062] When the pressing arm 310 moves along the first movement trajectory, one of the rotating members 311 rotates around the top of the second sub-groove 1112, and the other rotating member 311 moves in the arc-segment groove 1101; when the pressing arm 310 moves along the second movement trajectory, one of the rotating members 311 moves linearly from the top of the second sub-groove 1112 to the bottom of the second sub-groove 1112, and the other rotating member 311 transitions from the arc-segment groove 1101 to the straight-segment groove 1102 and moves linearly in the straight-segment groove 1102.

[0063] In a specific example, the arc-segment groove 1101 is a circular arc-segment groove with the rotation center of the driving arm 210 as the center of the circle.

[0064] See Figure 6 , in a possible implementation, the second groove 211 includes a third sub-groove 2111 and a fourth sub-groove 2112 that are perpendicular to each other and communicate. During the process of the pressing block assembly 300 rotating from the initial position to the pressure-holding position, the rotating member 311 moves in the third sub-groove 2111. During the process of the pressing block assembly 300 continuing to move linearly closer to the support platform 100 and pressing the workpiece to be pressure-held, the rotating member 311 moves in the fourth sub-groove 2112.

[0065] In this embodiment, the shape of the second groove 211 is optimized to optimize the connection manner of the driving arm 210, the support arm 110, and the pressing arm 310. Specifically, the second groove 211 is configured as an L-shaped groove structure including at least a third sub-groove 2111 and a fourth sub-groove 2112. The movement of the rotating member 311 in the third sub-groove 2111 corresponds to the first movement trajectory of the pressing arm 310, and the movement of the rotating member 311 in the fourth sub-groove 2112 corresponds to the second movement trajectory of the pressing arm 310.

[0066] Thus, during the process of rotating the pressure-holding device from the initial position to the pressure-holding position, the driving arm 210 rotates. At this time, the upper rotating member 311 moves in the arc-shaped groove 1101 towards the direction close to the linear groove 1102. At the same time, the rotating member 311 moves in the third sub-groove 2111, and the lower rotating member 311 rotates around the top of the second sub-groove 1112. Thus, the first movement trajectory of the pressing arm 310 is obtained; further driving the driving arm 210 to rotate so that the upper rotating member 311 transitions from the arc-shaped groove 1101 to the linear groove 1102. At this time, the upper rotating member 311 transitions from the third sub-groove 2111 to the fourth sub-groove 2112, and the lower rotating member 311 rotates around the top of the second sub-groove 1112, and the pressing arm 310 remains stationary in this state; further driving the driving arm 210 to rotate. At this time, the upper rotating member 311 moves linearly in the linear groove 1102. At the same time, the rotating member 311 moves linearly in the fourth sub-groove 2112, and the lower rotating member 311 moves linearly in the second sub-groove 1112. Thus, the second movement trajectory of the pressing arm 310 is obtained.

[0067] At the same time, when the pressure-holding device is in the pressure-holding state, the vertically connected third sub-groove 2111 and fourth sub-groove 2112 can lock the driving arm 210, the support arm 110, and the pressing arm 310, avoiding the reverse movement of the pressing arm 310 and the driving arm 210 due to the elastic force provided by the support platform 100 during unmanned operation, and further improving the pressure-holding stability and durability of the pressure-holding device.

[0068] In a specific example, the third sub-groove 2111 is a groove with a certain curvature, and the fourth sub-groove 2112 is a linear groove. Of course, in other embodiments, the third sub-groove 2111 can also be a linear groove.

[0069] In a specific example, the movement trajectory amplitude of the driving arm 210 in the third sub-groove 2111 is greater than the movement trajectory amplitude of the driving arm 210 in the fourth sub-groove 2112. Thus, the pressing mechanism has a sufficient opening and closing amplitude, providing sufficient working space for the operator to place the workpiece to be pressure-held in the accommodating groove 101 and removing the limitation of the working space. For example, but not limited to, the fully opened state of the pressing mechanism approaches 150°.

[0070] In a specific example, the driving arm 210 is rotationally connected to the support arm 110 through a ball bearing and a rotating shaft.

[0071] See Figure 6, in a possible implementation manner, when the briquetting assembly 300 is in a state of pressing the workpiece to be pressure-maintained, one of the rotating members 311 is located at the end of the linear groove 1102 of the first sub-groove 1111; the other rotating member 311 is located at the end of the second sub-groove 1112.

[0072] In this embodiment, the groove lengths of the linear groove 1102 and the second sub-groove 1112 are defined, so as to define the movement range of the briquetting assembly 300 in the vertical direction. Specifically, the groove lengths of the linear groove 1102 and the second sub-groove 1112 are set to be the same.

[0073] See Figure 8 , in a possible implementation manner, the rotating member 311 includes a rotating shaft 3111 and a bearing 3112 sleeved on the rotating shaft 3111, and the rotating shaft 3111 is fixedly connected to the pressing arm 310.

[0074] In this embodiment, the specific structure of the rotating member 311 is optimized. Specifically, the rotating member 311 is configured as a combined component at least including the rotating shaft 3111 and the bearing 3112. The rotating shaft 3111 is embedded in the bearing 3112. One end of the rotating shaft 3111 passes through the pressing arm 310 and is fixedly connected to the pressing arm 310. The other end of the rotating shaft 3111 is sleeved with a bearing 3112. The bearing 3112 passes through the support arm 110 and penetrates into the driving arm 210 to be movably connected to the driving arm 210. For example but not limited to, the rotating member 311 is a cam bearing.

[0075] See Figure 7 , in a possible implementation manner, there are two support arms 110, and the two support arms 110 are spaced apart. There are two driving arms 210, and the two driving arms 210 are respectively arranged corresponding to the two support arms 110. The briquetting assembly 300 includes two pressing arms 310, a carrier 320 and a briquetting block 330. The two pressing arms 310 are respectively movably connected to the two support arms 110 and the two driving arms 210. The carrier 320 is connected between the two pressing arms 310. The briquetting block 330 is correspondingly disposed in the accommodating groove 101 on one side of the carrier 320 facing the support platform 100.

[0076] In this embodiment, the specific structure of the pressing block assembly 300 is optimized to optimize the connection mode between the support arm 110 and the pressing mechanism. Specifically, two spaced support arms 110 and two driving arms 210 corresponding to the two support arms 110 respectively are configured. At the same time, the pressing block assembly 300 is configured as a combined component including at least two pressing arms 310, a carrier 320 and a pressing block 330. The two pressing arms 310 are respectively arranged corresponding to the two support arms 110 and the two driving arms 210. Specifically, the two pressing arms 310 are oppositely arranged on the outer sides of the two support arms 110, and the two driving arms 210 are arranged back to back on the inner sides of the two support arms 110. One driving arm 210, one support arm 110 and one pressing arm 310 form a driving mechanism. The carrier 320 is connected between the two pressing arms 310. In this way, when the driving arm 210 rotates, it drives the pressing arm 310 to move, and thus drives the carrier 320 to move. The pressing block 330 is arranged on the side of the carrier 320 facing the support platform 100. And when the pressing mechanism is in the pressure-holding position, the driving arm 210 abuts against the carrier 320, and the pressing block 330 is arranged corresponding to the accommodation groove 101 on the support platform 100. In this way, the workpiece to be pressure-held placed in the accommodation groove 101 is pressed and the pressure is maintained for the required time.

[0077] In a specific example, the carrier 320 can be connected to the two pressing arms 310 through fasteners such as screws / bolts, so as to improve the connection tightness between the carrier 320 and the pressing arms 310.

[0078] In a specific example, the carrier 320 is a carrier plate, and the pressing block 330 is a convex-shaped structural block. The support arm 110 is a plate-shaped structure, the driving arm 210 is a plate-shaped structure, and the pressing arm 310 is a plate-shaped structure.

[0079] See 1 and Figure 7 As shown in, in a possible implementation manner, the pressing block assembly 300 further includes a limiting member 340. The limiting member 340 is arranged on the side of the carrier 320 facing the support platform 100, and the side of the limiting member 340 away from the carrier 320 is flush with the side of the pressing block 330 away from the carrier 320.

[0080] In this embodiment, the specific structure of the pressing block assembly 300 is optimized. Specifically, the pressing block assembly 300 is configured as a combined component including at least two pressing arms 310, a carrier 320, a pressing block 330, and a limiting member 340. The pressing arm 310 is movably connected to the support arm 110. The carrier 320 is connected between the two pressing arms 310. The pressing block 330 is connected to the side of the carrier 320 facing the support platform 100. The limiting member 340 is connected to the side of the carrier 320 facing the support platform 100. When the pressing block 330 abuts against the workpiece to be pressure-maintained placed in the accommodation groove 101, the end of the limiting member 340 away from the carrier 320 also abuts against the support platform 100. In this way, by the abutment of the limiting member 340 against the support platform 100, the pressing block 330 is restricted from further extending into the accommodation groove 101, avoiding excessive extrusion of the workpiece to be pressure-maintained by the pressing block 330, thereby improving the pressure-maintaining quality of the workpiece to be pressure-maintained.

[0081] In a specific example, the limiting member 340 is a limiting rod / post. There are four limiting members 340, and the four limiting members 340 are distributed at the four corners of the carrier 320. In this way, a stable working environment is provided for the abutting and pressure-maintaining operation of the pressing block 330. At the same time, setting multiple limiting members 340 is beneficial to enabling the pressing block 330 to provide a uniform pressing force to the workpiece to be pressure-maintained, further improving the pressure-maintaining quality of the workpiece to be pressure-maintained.

[0082] See Figure 3 and Figure 7 , in a possible implementation manner, the pressing block assembly 300 further includes a plurality of first reinforcing ribs 350. The first reinforcing ribs 350 are arranged between the two pressing arms 310, and the plurality of first reinforcing ribs 350 are spaced apart in the extending direction of the pressing arm 310.

[0083] In this embodiment, the specific structure of the pressing block assembly 300 is further optimized. Specifically, the pressing block assembly 300 is configured as a combined component including at least two pressing arms 310, a carrier 320, a pressing block 330, and a plurality of first reinforcing ribs 350. The pressing arm 310 is movably connected to the support arm 110. The carrier 320 is connected between the two pressing arms 310. The pressing block 330 is connected to the side of the carrier 320 facing the support platform 100. The first reinforcing rib 350 is connected between the two pressing arms 310, and the plurality of first reinforcing ribs 350 are arranged at intervals along the extending direction of the arm body of the pressing arm 310. In this way, when the driving arm 210 rotates, it drives the pressing arm 310 to move, thereby driving the carrier 320 and the first reinforcing ribs 350 to move synchronously, and further driving the pressing block 330 on the carrier 320 to move closer to or away from the accommodation groove 101. When reaching the pressure-maintaining position, the driving arm 210 partially abuts against the first reinforcing rib 350 to further provide a downward pressing force to the pressing block 330.

[0084] In a specific example, there are two first reinforcing ribs 350, and the first reinforcing ribs 350 are respectively connected between two pressing arms 310 through fasteners such as screws / bolts. One of the first reinforcing ribs 350 is arranged corresponding to the bearing member 320, and the other first reinforcing rib 350 is arranged near the suspended end of the pressing arm 310. For example but not limited to, the first reinforcing rib 350 is in a plate-like structure or a columnar structure.

[0085] See Figure 9 and Figure 10 , in a possible implementation manner, there are two support arms 110, the two support arms 110 are arranged at intervals, the driving assembly 200 includes two driving arms 210 and a second reinforcing rib 220, the second reinforcing rib 220 is connected between the two driving arms 210, the two driving arms 210 are respectively rotatably connected to the two support arms 110, and the two driving arms 210 are movably connected to the pressing block assembly 300 to drive the pressing block assembly 300 to move.

[0086] In this embodiment, the specific structure of the driving assembly 200 is optimized to optimize the operation mode of the driving assembly 200. Specifically, two support arms 110 are configured, and at the same time, the driving assembly 200 is configured as a combined component including at least two driving arms 210 and a second reinforcing rib 220. The two ends of the second reinforcing rib 220 are respectively connected to the two driving arms 210, one ends of the two driving arms 210 are respectively rotatably connected to the two support arms 110, and the two driving arms 210 and the second reinforcing rib 220 form an H-shaped structural member. For example but not limited to, the second reinforcing rib 220 is in a plate-like structure or a columnar structure.

[0087] In a specific example, the driving assembly 200 further includes a handle 230, and the handle 230 is connected to the ends of the two driving arms 210 away from the support arms 110. In this way, it is convenient for the operator to hold the handle 230, thereby driving the two driving arms 210 to move, and further driving the pressing assembly to move. For example but not limited to, for the convenience of operation, the handle 230 is in a cylindrical structure, and an anti-slip and shock-absorbing sleeve such as a soft rubber sleeve can be sleeved outside the handle 230.

[0088] See Figures 11 to 13 , in a possible implementation manner, the support platform 100 includes a first carrier plate 120, a second carrier plate 130 and an elastic member 140. The first carrier plate 120 includes an operation area α and a fixed area β located on one side of the operation area α. The second carrier plate 130 is arranged in the operation area α. The elastic member 140 is connected between the second carrier plate 130 and the first carrier plate 120. The accommodation groove 101 is arranged on the side of the second carrier plate 130 away from the first carrier plate 120.

[0089] In this embodiment, the specific structure of the support platform 100 is optimized. Specifically, the support platform 100 is configured as a combined component including at least a first carrier plate 120, a second carrier plate 130, and an elastic member 140. The elastic member 140 is disposed between the first carrier plate 120 and the second carrier plate 130. In this way, when the pressing block assembly 300 abuts against the receiving groove 101 of the second carrier plate 130, the elastic member 140 provides a buffering force to the pressing block assembly 300, preventing the pressing block assembly 300 from directly colliding with the component to be pressure-maintained and causing mechanical damage / destruction / damage to the component to be pressure-maintained. At the same time, the elastic member 140 also provides an upward elastic pressing force to the second carrier plate 130. The upward elastic pressing force and the downward pressing force provided by the pressing block 330 cooperate with each other to provide a better pressure-maintaining environment and pressure-maintaining effect for the component to be pressure-maintained disposed between the second carrier plate 130 and the pressing block 330.

[0090] In a specific example, the elastic member 140 is a spring or a soft rubber elastomer, etc. The cross-sectional area of the first carrier plate 120 is larger than the cross-sectional area of the second carrier plate 130.

[0091] In a possible implementation manner, the pressure-maintaining device further includes a pressure sensor (not shown in the figure), a timer (not shown in the figure), a buzzer (not shown in the figure), and a control member (not shown in the figure). The pressure sensor, the timer, and the buzzer are all electrically connected to the control member;

[0092] The pressure sensor is disposed in the receiving groove 101 and is used to detect the pressure value provided by the pressing assembly to the component to be pressure-maintained;

[0093] After the pressure sensor reaches the set pressure, the control member controls the timer to start timing, and after the set time, controls the buzzer to emit an alarm sound.

[0094] In this embodiment, the specific structure of the pressure-maintaining device is further optimized. Specifically, the pressure-maintaining device is configured as a combined component including at least the support platform 100, a pressing mechanism, a pressure sensor, a timer, a buzzer, and a control member. The pressing mechanism is movably connected to the support arm 110 of the support platform 100. The pressure sensor is disposed in the receiving groove 101 of the support platform 100. In this way, when the pressing mechanism rotates to the pressure-maintaining position, the pressure sensor detects the pressure value provided by the pressing mechanism to the component to be pressure-maintained, and transmits the pressure value information to the control member. The control member controls the timer to operate according to the pressure value information. After the pressure value reaches the set pressure value, the control member controls the timer to start timing; the timer performs the timing operation and transmits the time information obtained by it to the control member. The control member controls the buzzer to operate according to the time information. After the time information reaches the set time, the control member controls the buzzer to emit an alarm sound to notify the operator that the pressure-maintaining operation of the component to be pressure-maintained is completed.

[0095] See Figure 14, in a possible implementation, the accommodation groove 101 includes a product groove 1011 and a picking groove 1012. The picking groove 1012 is provided adjacent to the product groove 1011 and is spaced from the product groove 1011. The product groove 1011 is used to accommodate the component to be pressure-maintained;

[0096] The pressure sensor is disposed in the product groove 1011.

[0097] In this embodiment, the structure of the accommodation groove 101 is optimized to improve the picking and placing efficiency of the component to be pressure-maintained. Specifically, the accommodation groove 101 is configured as a product groove 1011 and a picking groove 1012. The product groove 1011 is used to place the component to be pressure-maintained, and the picking groove 1012 is used to avoid part of the fingers or clamping tools of the operator when placing / taking the component to be pressure-maintained. In this way, it avoids the inconvenient operation of the operator having to pick out the pressure-maintained product from the product groove 1011, which is beneficial to the operator to collect the pressure-maintained product and effectively improves the pressure-maintaining operation efficiency. It should be understood that when the component to be pressure-maintained is placed in the product groove 1011, part of the component to be pressure-maintained is located in the picking groove 1012 for the operator to pick up.

[0098] For example but not limited to, the component to be pressure-maintained includes a first product and a second product. The first product is accommodated in the product groove 1011, one end of the second product is bonded to the first product through an adhesive such as glue, and the other end is partially accommodated in the picking groove 1012. In this way, the operator can pick up one end of the second product placed in the picking groove 1012 to realize the picking, placing and transferring of the pressure-maintained product. It should be understood that the second product can maintain its relative position with the first product through structures such as limit posts.

[0099] See Figure 1 , Figure 3 and Figure 5 , in a possible implementation, the pressure-maintaining device further includes a box body 400, and the support platform 100 is disposed on the top of the box body 400. The box body 400 is used to provide a vertical distance for the support platform 100 so that the pressure-maintaining device can perform pressure-maintaining operations at a certain height. In this way, on the one hand, it avoids the support platform 100 being directly placed on the ground and being contaminated and corroded by ground water / dust, etc., which is beneficial to extending the service life of the pressure-maintaining device; on the other hand, the pressure-maintaining operation at a certain height provides a relatively dry and less interfering pressure-maintaining environment for the component to be pressure-maintained, which is beneficial to improving the pressure-maintaining quality of the component to be pressure-maintained.

[0100] In a specific example, the box body 400 further includes a hand-held lug, and the hand-held lug protrudes from the side wall of the box body 400 to facilitate the operator to transfer and place the pressure-maintaining device.

[0101] Of course, in other embodiments, an avoidance notch 410 may be provided on the box body 400 to facilitate the transfer and placement of the pressure maintaining device by the operator. The avoidance notch 410 penetrates the side wall of the box body 400 so that the fingers of the operator can be partially inserted into the box body 400 to clamp and carry the pressure maintaining device. The provision of the avoidance notch 410 helps to streamline the structure of the box body 400 and realize the miniaturization process of the pressure maintaining device.
