Detailed Description

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless it is specifically stated otherwise.

The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.

In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of exemplary embodiments may have different values.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

The invention provides a split type pressure maintaining device for maintaining an irregular surface. The split type pressure maintaining device provided by the invention can simultaneously maintain pressure for a plurality of areas on the irregular surface of the product, so that the functions of effectively bonding two parts, directly pressing a formed product or preventing the formed product from deforming and the like are realized. The transmission assembly and the product placement structure can ensure that a plurality of pressure maintaining blocks simultaneously and accurately compress corresponding areas on the irregular surface, ensure the consistency of pressure maintaining and improve the pressure maintaining precision.

As shown in fig. 1, the base plate 10 has a mounting surface on which the product placement structure 29 and the drive assembly are mounted. The product placement structure 29 is fixedly mounted on the mounting surface, the product placement structure 29 is configured for fixing a product to be pressure-maintaining, and the product placement structure 29 is capable of accurately positioning the product to be pressure-maintaining. The phenomenon that the product to be pressure-maintaining is not placed in place or moves in the pressure maintaining process of the product is avoided, so that the pressure maintaining effect is affected.

Since the product to be pressure maintained has an irregular surface, it has different surface features thereon. Thus, before pressure maintenance, the irregular surface is divided into a plurality of independent pressure maintaining areas in advance according to the surface characteristics thereof. And according to different surface characteristics of the pressure maintaining areas, corresponding pressure maintaining is carried out on the pressure maintaining areas at the same time. Therefore, the pressure maintaining effect is good, and the consistency of the pressure maintaining of the irregular surface can be ensured. As shown in fig. 1, the number of the pressure maintaining blocks is equal to the number of the pressure maintaining areas. And each pressure maintaining block corresponds to one pressure maintaining area. Correspondingly, the plurality of transmission assemblies are configured to drive the pressure maintaining blocks to simultaneously downwards compress the corresponding pressure maintaining areas, so that pressure maintaining is realized. The transmission assembly may take a variety of transmission modes and structures, and the invention is not limited thereto, and for example, pneumatic, hydraulic or electric transmission modes and structures may be employed.

Each transmission assembly at least drives one pressure maintaining block to press downwards. In a preferred embodiment of the invention, as shown in fig. 1, each of the transmission assemblies individually drives one of the hold-down blocks to press down on the hold-down region. For example, several of the transmission assemblies may be provided to have the same structure and operation, and several of the pressure maintaining blocks may have different shapes according to different structures of the surface of the product to be pressure maintained.

In order to obtain a better pressure maintaining effect, it is preferable that each of the pressure maintaining blocks has a pressure maintaining surface matching with the shape of the corresponding pressure maintaining area. Therefore, when the plurality of transmission assemblies drive the pressure maintaining blocks to downwards press the corresponding pressure maintaining areas, the pressure maintaining surfaces are matched with the pressure maintaining areas, so that a better pressing effect is obtained.

Furthermore, the pressure maintaining surfaces of the pressure maintaining blocks can completely cover the irregular surfaces of the products during pressure maintaining, and the pressure maintaining mode can not only obtain the excellent mutual bonding and pressing fixing effect between the components, but also directly press-fit the irregular surfaces of special materials.

It should be appreciated that in the embodiment of compression fitting: before pressure maintaining, the product has an irregular shape, and pressure maintaining lamination is performed according to the problem that adhesion lamination between irregular structures is difficult. In embodiments where irregular surfaces are directly compression molded: the irregular surface is a preset shape, and can be obtained specifically only after press molding.

Preferably, as shown in fig. 2, each of the transmission assemblies includes a first transmission assembly and a second transmission assembly. The first transmission assembly is mounted on the mounting surface and the second transmission assembly is mounted on the first transmission assembly. The first drive assembly is configured to reciprocate a second drive assembly thereon parallel to the mounting surface to effect parallel feed of the pressure block 14. After the pressure maintaining block 14 is moved into position parallel to the mounting surface, the second transmission assembly is configured to directly drive the pressure maintaining block 14 to reciprocate perpendicular to the mounting surface to achieve a vertical compression action. After the pressing is performed for a certain time, the second transmission assembly resets to drive the pressure maintaining block 14 to move upwards to be away from the product to be maintained. And then, the first transmission assembly is reset to drive the second transmission assembly and the pressure maintaining block 14 to be far away from the product to be maintained so as to conveniently take out the product to be maintained. It should be understood by those skilled in the art that the second transmission assembly is fixedly connected to the first transmission assembly and moves cooperatively with each other to implement the compressing and resetting functions of the voltage-maintaining block 14, and the starting sequence, the running speed and the movement track of the second transmission assembly and the first transmission assembly are not particularly limited, so long as the compressing and resetting functions of the voltage-maintaining block 14 can be implemented.

Specifically, the irregular surface of the product to be pressurized is a contoured face curved surface on the virtual reality glasses. The pressurize is used for compressing tightly laminating profile modeling face curved surface on VR glasses main part. According to the bilateral symmetry structure of the profiling face, the curved surface of the profiling face can be divided into three pairs of pressure maintaining areas, and each pair of pressure maintaining areas are oppositely arranged. For example, the pressure maintaining areas may be left and right forehead, left and right eyes, and left and right cheek portions of the curved surface of the contoured face. Correspondingly, the split type pressure maintaining device comprises three pairs of transmission assemblies and three pairs of pressure maintaining blocks aiming at the curved surface of the profiling face. For example, as shown in fig. 1, three pairs of holding blocks are holding block 11, holding block 12, holding block 13, holding block 14, holding block 15, and holding block 16, respectively. Each transmission assembly corresponds to one pressure maintaining block respectively and can drive the pressure maintaining blocks to reciprocate. The three pairs of pressure maintaining blocks respectively correspond to the three pairs of pressure maintaining areas of the profile modeling face curved surface, and each pair of transmission components is respectively arranged on two sides of each pair of pressure maintaining areas. The first transmission components of each pair of transmission components move in opposite directions at the same time, so that parallel feeding of the pressure maintaining blocks is realized.

Further, as shown in fig. 2, the second transmission assembly includes a fixed plate 25 and a second cylinder 26. The fixed plate 25 is mounted on the first transmission assembly. The second cylinder 26 is mounted on the fixing plate 25. The second cylinder 26 is a rodless cylinder configured to directly drive the dwell block to reciprocate. For example, a piston can be arranged in the rodless cylinder, the piston is arranged in a piston guide rail, the piston is fixedly connected with a pressure maintaining block, and the piston is pushed to reciprocate along the piston guide rail by means of air inlet; furthermore, the rodless cylinder may also be provided as a magnetically coupled rodless cylinder. The rodless cylinder is small in installation size, and the phenomenon that the rodless cylinder is rubbed against a product to be pressurized due to oversized size is avoided. Meanwhile, the rodless cylinder is provided with buffering and the displacement distance is accurate, so that the phenomenon that the product to be pressurized is damaged due to the fact that the product to be pressurized is collided with the excessive displacement when the pressurizing block is driven to perform vertical feeding is avoided.

Further, as shown in fig. 2, the first transmission assembly includes a fixing base 17, a first cylinder 18, a sliding assembly and a limit buffer 24. The fixing base 17 is mounted on the mounting surface, and the first cylinder 18 is mounted on the fixing base 17. The second transmission assembly is mounted on the slide assembly. The first cylinder 18 is configured for driving the sliding assembly to reciprocate parallel to the mounting surface via a connecting rod. The limit bumper 24 is configured to cushion limit the first cylinder 18.

Alternatively, as shown in fig. 2, the sliding assembly includes a sliding guide rail 23, a slider 22, a slider connection plate 21, and an L-shaped connection member 19. The slide rail 23 is mounted on the mounting surface. The connecting rod of the first cylinder 18 is fixedly connected with the short side of the L-shaped connecting piece 19. The slide connection plate is fixed with the long side of the L-shaped connecting piece 19, and the slide connection plate 21 is fixed with the slide 22. For example, the connecting rod of the first cylinder 18 may be fixedly connected to the short side of the L-shaped connector 19 through a floating joint 20. The first cylinder 18 drives the slider 22 to reciprocate along the slide rail 23. The structure of the slider assembly in the present invention is not exclusive and other structures are possible. For example, the slider assembly may also be integrally provided.

It will be appreciated by those skilled in the art that the manner and configuration of the first and second drive assemblies is not exclusive. Other transmission means and arrangements of the first transmission assembly and the second transmission assembly are possible, such as hydraulic transmission, electric transmission or pneumatic transmission of other arrangements.

Preferably, as shown in fig. 1, the split type pressure maintaining device further comprises a detection unit 28 and a control unit 27. The detecting unit 28 is configured to detect whether the product to be pressure-maintained is put in place, so as to avoid deformation or damage of the product caused by pressure maintaining of the product to be pressure-maintained, which is not put in place, by the pressure maintaining block. The control unit 27 is configured to operate the transmission assembly upon receipt of a start signal and to reset the transmission assembly upon receipt of a reset signal.

Further, the control unit 27 communicates with the detection unit 28. The control unit 27 is configured to automatically detect the product placement position by the detection unit 28 after receiving the start signal, and to operate the transmission assembly if it is detected that the product is in place; and if the product is detected not to be placed in place, the transmission assembly is not operated, so that a user can adjust the placement position of the product to be pressurized.

Further, the control unit 27 may send out an alarm signal to alert the user that the product is not in place when receiving the detection result. For example, the alert signal may be in the form of a sound, a flashing light, or the like.

Further, as shown in fig. 1, the detection unit 28 includes an optical fiber transmitting device and an optical fiber receiving device. The optical fiber transmitting device is configured to transmit the light pulses to the optical fiber receiving device, which is configured to receive the light pulses. For example, a fiber holder may be provided on the base plate 10, and the fiber emitting device and the fiber receiving device may be fixed to the fiber holder. If the optical fiber receiving device does not receive the light pulse, the product is not put in place. If the optical fiber receiving device receives the light pulse, the product is put in place. For example, a photosensitive element may be provided within the fiber optic receiver that senses the light pulses, and the photosensitive element may be in electrical communication with the control unit 27.

In order to protect the internal components, it is preferable that the split type pressure maintaining apparatus further includes a protection cover 30 detachably coupled to the base plate 10, as shown in fig. 3. The protective cover 30 is detachably connected with the bottom plate 10, so that internal parts can be maintained conveniently. The protecting cover 30 is provided with a taking and placing window 31, and the taking and placing window 31 corresponds to the product placing structure 29 in position, so that the pressure maintaining component can be taken and placed conveniently.

In addition, a controller power switch, a transmission assembly starting button and a transmission assembly reset button can be arranged on the split type pressure maintaining device. The transmission assembly starting buttons can be arranged in two, and the transmission assembly can only run when being pressed down simultaneously, so that hands of an operator are outside the device, and accidental injury is avoided.
