Description

Technical Field

[0001] This utility model belongs to the technical field of workpiece assembly equipment, and specifically relates to a pressing device. Background Technology

[0002] With the rapid development of high-tech industries such as electronic equipment and semiconductors, the requirements for precision manufacturing equipment are constantly increasing. In processes that require pressure to join multiple different workpieces, the need to accurately control the pressing force and the uniformity of pressing has become a key issue.

[0003] Traditional pressing devices typically apply pressing force directly to the workpiece through a fixed pressing panel. Although this method is simple in structure, the pressing force is generally controlled by a fixed program or manually, which can lead to problems such as uneven pressing force. Moreover, the process is often only applicable to workpieces of the same specification, which has significant limitations.

[0004] To address the above issues, some pressing devices employ a design that allows for manual or mechanical adjustment of the spacing. However, adjusting specific parameters still requires manual intervention, which compromises accuracy and stability, potentially impacting production efficiency and product quality. Utility Model Content

[0005] In order to overcome the defects of the prior art, the present invention proposes a pressing device, including a worktable for placing a substrate, a support, a lifting mechanism and a pressing mechanism. The support is disposed on the worktable, and the pressing mechanism is disposed above the worktable and is movably connected to the support through the lifting mechanism, so as to move closer to or away from the worktable based on the driving of the lifting mechanism.

[0006] The pressing mechanism includes a pressing panel and a plurality of pressing components disposed on the pressing panel. Each pressing component includes an elastic element, a connector fixedly connected to the pressing panel, and a movable pressing component movably connected to the connector. The movable pressing component is disposed on the side of the pressing panel facing the worktable. One end of the elastic element abuts against the movable pressing component, and the other end abuts against the connector or the pressing panel.

[0007] Preferably, the movable pressing component includes a negative pressure suction cup, and each pressing component has a pipe inside that connects the negative pressure suction cup to an external negative pressure mechanism.

[0008] Specifically, the connector includes a connecting seat, which is disposed on the side of the pressing panel away from the worktable;

[0009] The movable pressing component is movably sleeved in the connecting seat, and the elastic element abuts against the movable pressing component and the pressing panel respectively.

[0010] Specifically, the lifting mechanism includes a movable rod passing through the bracket, the movable rod being connected to the pressing mechanism, and the extension direction of the movable rod being perpendicular to the worktable.

[0011] Furthermore, the lifting mechanism also includes several guide rods, the extension direction of each guide rod being parallel to the movable rod;

[0012] Each of the guide rods is fixedly connected to one of the bracket and the pressing mechanism, and is movably disposed in a guide seat fixedly disposed on the other of the bracket and the pressing mechanism.

[0013] Preferably, the pressing mechanism further includes a rotating component, which is rotatably connected to the lifting mechanism via the rotating component, and the rotation axis of the rotating component is parallel to the worktable.

[0014] Furthermore, the lifting mechanism includes a limiting plate, which is disposed on the rotation path of the rotating member to limit the rotation range of the pressing mechanism.

[0015] Preferably, the pressing mechanism further includes a positioning member disposed on the pressing panel, the positioning member and the movable pressing member being disposed on the same side of the pressing panel;

[0016] The length of the positioning member relative to the pressing panel is shorter than the length of the movable pressing member relative to the pressing panel when the elastic member is in its natural state, but not shorter than the length of the movable pressing member relative to the pressing panel when the elastic member is in its maximum compressed state.

[0017] Preferably, the side of each positioning member facing the worktable is hemispherical and its spherical surface faces the worktable.

[0018] Preferably, the connection between each positioning member and the pressing panel includes a detachable connection.

[0019] This utility model has at least the following beneficial effects:

[0020] The pressing panel of the pressing device proposed in this utility model is provided with multiple pressing components containing elastic elements, which can apply pressure to the substrate at multiple points, thereby avoiding concentrated pressure. The use of elastic elements makes the pressing force have a certain elasticity and flexibility, making the pressing process more stable, ensuring the uniformity and stability of pressing, improving the overall pressing effect, and being applicable to different substrate shapes and material properties.

[0021] Furthermore, the pressing device proposed in this utility model can effectively adsorb the workpiece onto the pressing panel through a negative pressure suction cup, ensuring the stability of the workpiece during the pressing process and preventing it from moving due to external interference or equipment vibration. The movable pressing part is connected to the pressing panel through a connecting seat, allowing the movable pressing part to move freely within the connecting seat, thereby simplifying the device structure and improving the convenience of assembly and adjustment.

[0022] The design of the lifting mechanism's movable rod perpendicular to the worktable allows the pressing panel to be precisely adjusted up and down, flexibly adapting to workpieces of different heights and providing stable pressing force. The parallel design of the guide rod prevents the movable rod from shifting or wobbling during lifting, ensuring that the pressing panel remains stable and thus guaranteeing pressing accuracy. The rotating component allows the pressing mechanism to not only move up and down but also rotate, enabling it to connect substrates and other workpieces from different angles via negative pressure suction cups. This also facilitates user operation of the substrate surface or the workpiece pressed against the substrate. The accompanying limiting plate restricts the rotation range of the rotating component, thus preventing unnecessary damage or structural instability caused by excessive rotation of the pressing assembly.

[0023] The relative length design of the positioning component and the movable pressing component helps to improve the pressing accuracy, allowing the pressing component to stay in the precise position during pressing, avoiding excessive or insufficient pressing force. The hemispherical design can concentrate the pressure on the point of the movable pressing component, optimizing the pressing effect. The detachable design allows for easy replacement of positioning components of different shapes or materials or adjustment of the length of the positioning component relative to the pressing panel in different pressing processes.

[0024] Therefore, this utility model proposes a pressing device. The pressing device proposed in this utility model adopts multiple movable pressing components including elastic elements, which can provide uniform and controllable pressing force. The pressing mechanism is movably connected to the support through a lifting mechanism, which can flexibly adjust the distance between the pressing mechanism and the worktable. This allows the device to adjust the pressing force and pressing height according to the size, thickness and pressing requirements of different substrates, thereby meeting different process requirements.

[0040] Example 1

[0041] Please see Figures 1-4 This embodiment proposes a pressing device, including a worktable 1 for placing a substrate, a support 2, a lifting mechanism 3, and a pressing mechanism 4. The worktable 1 provides stable support as a platform for placing the substrate. The support 2 is set on the worktable 1 as a support structure for the pressing mechanism 4. The pressing mechanism 4 is set above the worktable 1 and is movably connected to the support 2 through the lifting mechanism 3, so as to move closer to or away from the worktable 1 based on the driving of the lifting mechanism 3. In this embodiment, the lifting mechanism 3 drives the vertical movement of the pressing mechanism 4 through the lifting drive of the driving component, thereby precisely controlling its rise and fall, which can meet the pressing requirements of substrates with different thicknesses.

[0042] The pressing mechanism 4 includes a pressing panel 41 and a plurality of pressing components disposed on the pressing panel 41. Each pressing component includes an elastic member 42, a connector fixedly connected to the pressing panel 41, and a movable pressing member 44 movably connected to the connector. The movable pressing member 44 is disposed on the side of the pressing panel 41 facing the worktable 1. One end of the elastic member 42 abuts against the movable pressing member 44, and the other end abuts against the connector or the side of the pressing panel 41 facing the worktable 1. The movable pressing member 44 is responsible for bringing the bonding member into contact with the substrate and applying pressure. With the assistance of the elastic member 42, the pressure can be adjusted to ensure a uniform pressure distribution during the pressing process. For example, when the bonding member includes an adhesive backing, the movable pressing member 44 can make the substrate and the adhesive backing fully contact each other to bond the substrate and the adhesive backing.

[0043] Preferably, the movable pressing component 44 includes a negative pressure suction cup 45. Each pressing component has a pipe 441 inside that connects the negative pressure suction cup 45 to the external negative pressure mechanism, so that the negative pressure mechanism can use the pipe 48 to make the negative pressure suction cup 45 have an adsorption force that can adsorb the substrate or the bonding component, effectively preventing the offset problem caused by uneven pressure or slippage during the bonding process, and ensuring the stability of the device; in this embodiment, the pipe 48 is disposed inside the movable pressing component 44.

[0044] Specifically, the connector includes a connecting seat 43, which is located on the side of the pressing panel 41 away from the worktable 1. The movable pressing member 44 is movably fitted in the connecting seat 43. The movable pressing member 44 is provided with a protruding limiting part. The elastic member 42 abuts against the limiting part of the movable pressing member 44 and the side of the pressing panel 41 facing the worktable 1, respectively. The connecting seat 43 allows the movable pressing member 44 to slide or move inside it, ensuring that the movable pressing member 44 can move freely in the vertical direction, and provides the pressure required for the fit through the elastic member 42.

[0045] Specifically, the lifting mechanism 3 includes a movable rod 31 passing through the bracket 2 and several guide rods 32. The extension direction of the movable rod 31 is perpendicular to the worktable 1. The lifting mechanism 3 drives the pressing panel 41 to move in the vertical direction through the movement of the movable rod 31, ensuring that the movable pressing component 44 can press the substrate based on the driving of the lifting mechanism 3.

[0046] Each guide rod 32 extends parallel to the movable rod 31. Each guide rod 32 is fixedly connected to one of the bracket 2 and the pressing mechanism 4, and is movably disposed in the guide seat 21 fixedly disposed on the other of the bracket 2 and the pressing mechanism 4. The guide rod 32 has the same direction of movement as the movable rod 31, and can move up and down synchronously in the guide seat 21 based on the driving of the movable rod 31. At the same time, it provides guidance for the movement of the movable rod 31, ensuring the smoothness and accuracy of the vertical movement of the movable rod 31, and avoiding tilting or deviation of the lifting mechanism 3 during the movement. In this embodiment, the guide rod 32 is fixedly connected to the pressing mechanism 4 and movably disposed in the guide seat 21 fixedly disposed on the lifting mechanism 3.

[0047] Preferably, the pressing mechanism 4 further includes a rotating component 46, which is rotatably connected to the lifting mechanism 3. The rotation axis of the rotating component 46 is parallel to the worktable 1. Through the rotating component 46, the pressing mechanism 4 can also rotate around a horizontal rotation axis parallel to the worktable 1, so that the pressing mechanism 4 can connect workpieces such as substrates from different angles through the negative pressure suction cup 45. At the same time, the device can adsorb substrates or bonding parts through the negative pressure suction cup 45, thereby facilitating users to perform other process operations on substrates or bonding parts.

[0048] Accordingly, the lifting mechanism 3 includes a limiting plate 33, a movable rod 31 and a guide rod 32 connected to the pressing mechanism 4 through the limiting plate 33. The limiting plate 33 is set on the rotation path of the rotating part 46 to limit the rotation range of the pressing mechanism 4. The setting of the limiting plate 33 can effectively limit the rotation angle of the pressing mechanism 4 and avoid excessive rotation of the pressing mechanism 4, which could lead to contact between the pressing panel 41 in the pressing mechanism 4 and the lifting mechanism 3, and thus cause the device to malfunction.

[0049] Preferably, the pressing mechanism 4 further includes a positioning member 47 disposed on the pressing panel 41. The positioning member 47 and the movable pressing member 44 are disposed on the same side of the pressing panel 41. In this embodiment, the side of the positioning member 47 facing the worktable 1 is spherical or hemispherical and its spherical surface faces the worktable 1. Compared with a flat or angular design, the hemispherical design can prevent damage or uneven pressing that may be caused by concentrated pressure on the positioning member 47. It also helps to cooperate with the movable pressing member 44 so that the movable pressing member 44 can more naturally and evenly distribute the pressing force on the substrate or the bonding member.

[0050] The length of the positioning member 47 relative to the pressing panel 41 is shorter than the length of the movable pressing member 44 relative to the pressing panel 41 when the elastic member 42 is in its natural state, but not shorter than the length of the movable pressing member 44 relative to the pressing panel 41 when the elastic member 42 is in its maximum compressed state.

[0051] The positioning element 47 can assist in distributing pressure, so that the movable pressing element 44 can better contact the substrate or bonding element. Through the positioning element 47, the pressing device proposed in this embodiment can effectively limit the vertical movement distance of the movable pressing element 44, prevent the movable pressing element 44 from being pressed down excessively during the pressing process, and thus avoid the device and substrate from malfunctioning or being damaged.

[0052] Preferably, each positioning element 47 is detachably connected to the pressing panel 41. The detachable connection design allows the positioning element 47 to be easily disassembled, thus facilitating the replacement of the positioning element 47 when different shapes or materials of positioning elements 47 are required in different pressing processes. In this embodiment, each positioning element 47 is detachably connected to the pressing panel 41 by bolts, so that the user can easily adjust the length of the positioning element 47 relative to the pressing panel 41 by bolts, thereby adapting to different needs.

[0053] In this embodiment, the pressing components are symmetrically arranged on the pressing panel 41, and the positioning components 47 are symmetrically arranged on the pressing panel 41. The pressing components and the positioning components 47 have the same axis of symmetry in their symmetrical arrangement on the pressing panel 41. The symmetrical arrangement of the pressing components and the positioning components 47 in the pressing mechanism 4 can effectively avoid excessive pressure concentration or uneven distribution, and ensure the consistency of the pressing effect.

[0054] In summary, this utility model proposes a pressing device. The pressing device of this utility model adopts multiple movable pressing components including elastic elements, which can provide uniform and controllable pressing force. The pressing mechanism is movably connected to the support through a lifting mechanism, which can flexibly adjust the distance between the pressing mechanism and the worktable. This allows the device to adjust the pressing force and pressing height according to the size, thickness and pressing requirements of different substrates, thereby meeting different process requirements.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
