Description

Technical Field

[0001] The invention relates to the technical field of assembly equipment, and in particular to vacuum assembly equipment. Background Art

[0002] With the advancement of science and technology, the technology applied to wearable devices is developing more and more rapidly. As a result, there are more and more types of wearable devices, which can better meet people's growing needs. Among them, virtual reality head-mounted display equipment, referred to as VR head display or VR glasses, is a relatively new wearable device. It uses computer and sensor technology to realize a new human-computer interaction mode, thereby achieving a better user experience. In order to meet visual needs, the two lenses of VR glasses are stacked structures. The assembly process requires the two lenses to be stacked. Specifically, glue is first applied on one lens, and then the other lens is placed on the glued lens, and it needs to be bonded under a vacuum environment. Generally, when placing the second lens, a mechanical arm or a similar mechanism is required to carry a suction cup to absorb the lens and complete the transfer of the lens. When the lens is placed, the pick-up piece needs to be removed and the two lenses need to be moved into the vacuum chamber. The moving process will cause the two lenses to be misaligned, thereby affecting the matching accuracy; or the vacuum cover can be directly lowered, but the pick-up piece must first be raised and transferred to the side to avoid interference with the vacuum cover, but the movement of the pick-up piece leads to low assembly efficiency.

DETAILED DESCRIPTION

[0047] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0048] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0049] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0050] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0051] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0052] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts.

For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0054] like Figures 1 to 6 As shown, this embodiment provides a vacuum assembly device for completing the bonding assembly of a first workpiece and a second workpiece, wherein the first workpiece and the second workpiece are both products such as lenses that need to be assembled in a vacuum environment. The vacuum assembly device includes a frame 100, an assembly tool 200, a moving component 300, a vacuum cover 400, a picking member 500 and a picking drive member 600. Among them, the frame 100 has a loading station and an assembly station spaced apart along a first direction; the assembly tool 200 can be moved to the assembly station and is used to carry the first workpiece; the moving component 300 is arranged on the frame 100, and the moving component 300 includes a moving member 310 that can reciprocate above the loading station and the assembly station along the first direction; the vacuum cover 400 has a vacuum chamber 410 and an opening 420 connected to the vacuum chamber 410, and at least one of the vacuum cover 400 and the assembly tool 200 can be moved along a direction perpendicular to the first direction. The second direction of the second workpiece 420 is close to another direction of the second workpiece 420 so that the assembly tool 200 blocks the opening 420. The second direction is the assembly direction of the first workpiece and the second workpiece. The picking member 500 is located in the vacuum cover 400 and can move synchronously with the first direction. The picking member 500 is used to pick up the second workpiece. The picking drive member 600 is relatively fixed to the moving member 310, and its output end can reciprocate along the second direction, and is connected to the picking member 500 to drive the picking member 500 to extend out of the vacuum chamber 410 or be hidden in the vacuum chamber 410.

[0055] With the aid of the above structure, when in use, the picking member 500 first picks up the second workpiece at the loading station, and then, driven by the moving member 310, moves from the loading station to the assembly station. In the second direction, one of the vacuum cover 400 and the assembly tool 200 is close to the other, thereby closing the opening 420 of the vacuum chamber 410. In this process, since the second direction is the assembly direction of the first workpiece and the second workpiece, the two workpieces will not be misaligned or offset, thereby ensuring the assembly accuracy of the two. In addition, after the two workpieces are assembled, the picking member 500 can be moved to the inside of the vacuum cover 400, so there is no need to remove it, saving time and improving assembly efficiency. Finally, the picking member 500 can also pressurize the second workpiece in a vacuum environment so that the second workpiece and the first workpiece are pressed tightly, thereby ensuring the bonding effect of the two workpieces.

[0056] For ease of understanding, refer to Figure 1 As shown, in some embodiments, the first direction is the left-right direction, and the second direction is the vertical direction, that is, the up-down direction.

[0057] In some embodiments, the vacuum cover 400 is movably disposed on the moving part 310 along the second direction, and can approach or move away from the assembly tool 200. When the vacuum cover 400 approaches the assembly tool 200, the assembly tool 200 blocks the opening 420. The vacuum assembly equipment further includes a vacuum driving part 700, which is disposed on the moving part 310, and its output end is transmission-connected with the vacuum cover 400. This arrangement ensures that the positions of the first workpiece and the second workpiece will not change, thereby facilitating the position stability between the two.

[0058] In other embodiments, the assembly tool 200 may be raised to approach the vacuum cover 400 and seal the opening 420 of the vacuum cover 400 . An annular sealing strip is provided around the opening 420 to seal the vacuum chamber 410 .

[0059] Regarding the positional relationship between the pick-up drive member 600 and the vacuum cover 400, in some embodiments, the pick-up drive member 600 is located outside the vacuum cover 400, and the vacuum cover 400 also has a connecting channel connected to the vacuum chamber 410. The vacuum assembly equipment also includes a connecting shaft 510, which is sealed and penetrates the connecting channel and can reciprocate relative to the vacuum cover 400 along the second direction. One end of the connecting shaft 510 is connected to the output end of the pick-up drive member 600, and the other end is connected to the pick-up member 500; when the vacuum cover 400 is away from the assembly container 200, the pick-up member 500 can extend out of the vacuum chamber 410 and can be hidden in the vacuum chamber 410, and when the vacuum cover 400 is close to the assembly container 200, the pick-up member 500 is hidden in the vacuum chamber 410. The above arrangement helps to reduce the height of the vacuum assembly equipment and makes the volume of the vacuum chamber 410 as small as possible after the assembly tool 200 blocks the opening 420 of the vacuum cover 400, so as to shorten the vacuum pumping time and improve the assembly efficiency.

[0060] Since the connecting shaft 510 is disposed in the connecting channel, in order to achieve sealing, the connecting shaft 510 is connected to the connecting channel. Figure 4 and Figure 5 As shown, in some embodiments, the upper side surface of the top cover plate 430 of the vacuum cover 400 is concavely provided with a first step groove 431 downwardly, and the upper side surface of the top cover plate 430 is detachably connected with a first sealing end cover 432, which blocks the first step groove 431 and forms a first annular groove whose notch is connected to the connecting channel, and a first annular seal 433 is interference-fitted in the first annular groove, and the connecting shaft 510 is penetrated in the first annular seal 433. The lower side surface of the top cover plate 430 of the vacuum cover 400 is concavely provided with a second step groove 434 upwardly, and the lower side surface of the top cover plate 430 is detachably connected with a second sealing end cover 435, and the second sealing end cover 435 blocks the second step groove 434 and forms a second annular groove whose notch is connected to the connecting channel, and a second annular seal 436 is interference-fitted in the second annular groove, and the connecting shaft 510 is penetrated in the second annular seal 436. The above arrangement allows that during installation, only the connecting shaft 510 needs to be inserted into the connecting passage, and then the first annular seal 433 and the second annular seal 436 are respectively inserted into the connecting shaft 510 from both ends of the connecting shaft 510, and finally the first sealing end cover 432 and the second sealing end cover 435 are respectively inserted into the connecting shaft 510 from both ends of the connecting shaft 510, and are respectively connected to the upper side and the lower side of the top cover 430, thereby improving the installation efficiency and ensuring the position stability of the two seals. Since the sealing end cover squeezes the annular seal to deform it, it abuts against the connecting shaft 510.

[0061] The vacuum assembly device further includes a frame 320, and a slide rail 324 extending along the second direction is arranged on the outer side of the frame 320; a connecting plate 440 is installed on the upper side of the vacuum cover 400, and the other end of the connecting plate 440 is slidably matched with the slide rail 324 through a slider; wherein the frame 320 has an accommodating channel 321 passing through along the second direction, and at least a part of the pickup driving member 600 is located inside the accommodating channel 321. The vacuum driving member 700 is fixed on the outer side of the frame 320.

[0062] First, the setting of the slide rail 324 and the slider makes the movement of the vacuum hood 400 smoother and more stable; secondly, an accommodating channel 321 is set inside the frame 320 supporting the slide rail 324 to place the picking drive 600, which can not only ensure that the connecting shaft 510 is located in a relatively middle position of the vacuum hood 400, but also reasonably utilize the internal space of the frame 320, reduce the external occupancy of the frame 320, and provide sufficient options for the installation of the vacuum drive 700 to avoid interference.

[0063] Specifically, the frame 320 includes two side plates 322 disposed opposite to each other and an outer plate 323 disposed between the side plates 322, and the outer plate 323 is parallel to the plate-shaped moving member 310. Two slide rails 324 are disposed on each side plate 322, and two sliders are slidably disposed on each slide rail 324 to further ensure the stability of the vacuum cover 400 during the sliding process.

[0064] In order to ensure the picking efficiency of the second workpiece, the picking surface of the picking member 500 is provided with a plurality of suction nozzles 520 arranged at intervals, the picking member 500 is provided with a first vacuum joint 530, the picking member 500 is connected with a vacuum channel between the first vacuum joint 530 and the suction nozzle 520, the vacuum cover 400 is provided with a connecting hole, the connecting hole is provided with a second vacuum joint 450, the inlet of the second vacuum joint 450 is connected with the vacuum equipment, the outlet of the second vacuum joint 450 is connected with one end of the vacuum hose, and the other end of the vacuum hose is connected with the first vacuum joint 530. The picking surface of the picking member 500 is a curved surface to match the curved lens. The second vacuum joint 450 may have two vacuum outlets, one of which is connected with the vacuum hose; the other vacuum outlet is connected with one end of the vacuum pipeline, the other end of the vacuum pipeline is connected with the vacuum chamber 410, and a valve body is provided on the vacuum pipeline to control the on and off of the vacuum pipeline. The above arrangement can be used to absorb the second workpiece and also to evacuate the vacuum chamber 410 through a second vacuum connector 450. The inlet of the second vacuum connector 450 is connected to a vacuum device.

[0065] In other embodiments, the vacuum cover 400 has a vacuum port connected to the vacuum chamber 410 , and the vacuum port is connected to a vacuum device.

[0066] Before the second workpiece is placed on the first workpiece, the upper surface of the first workpiece has been coated with glue. To improve bonding efficiency and reduce vacuum time, a first irradiation assembly 470 is provided inside the vacuum cover 400. The first irradiation assembly 470 can emit light to initially solidify the glue between the second workpiece and the first workpiece. The provision of the first irradiation assembly 470 shortens the glue solidification time, thereby shortening the vacuum holding time and improving assembly efficiency.

[0067] A perspective window 460 is provided on the side wall of the vacuum cover 400 for observing the assembly status, so as to observe the assembly effect.

[0068] In some embodiments, the moving assembly 300 further includes a linear module 330 , and the moving member 310 is disposed at an output end of the linear module 330 to reciprocate in a first direction.

[0069] In some embodiments, the vacuum assembly equipment further includes a glue dispensing assembly 810, a first guide rail 820 and a second guide rail 830. The first guide rail 820 extends along a third direction and is used to transfer the second workpiece to the loading station; the second guide rail 830 extends along a third direction and is used to transfer the assembly vehicle 200 carrying the first workpiece through the glue dispensing station and the assembly station in sequence; the glue dispensing assembly 810 is arranged on the frame 100 and is used to dispense glue to the first workpiece located at the glue dispensing station. This arrangement allows the first workpiece and the second workpiece to be transferred through two guide rails, thereby avoiding interference and improving the efficiency of workpiece transfer and assembly. In this embodiment, the third direction is the front-to-back direction.

[0070] In order to ensure that the glue between the two workpieces is fully solidified, in some embodiments, the vacuum assembly equipment also includes a second irradiation component 840, which is arranged on the frame 100 and can emit light to the curing station so that the glue between the second workpiece and the first workpiece is completely solidified. Among them, the second irradiation component 840 is located between the dispensing station and the assembly station. This arrangement allows the second workpiece and the first workpiece to be returned to the second irradiation component 840 after the assembly is completed, so as to complete the secondary light curing. Since the dispensing process is relatively long, it will not conflict with the dispensing process. Before the first workpiece in the next assembly process is completed, the second workpiece and the first workpiece in the previous assembly process have been cured and transferred to the unloading station or transferred to the outside of the second guide rail 830 by the robot, and then the first workpiece that has completed the dispensing is moved to the assembly station.

[0071] The vacuum assembly equipment further includes a first photographing component 910 , which is disposed on the moving component 310 to photograph the second workpiece located at the loading station, thereby ensuring that the picking component 500 accurately picks up the second workpiece.

[0072] After assembly, it is necessary to ensure that the pick-up member 500 is moved along the second direction, so that the first workpiece and the second workpiece can be fitted at all places without any gap. Since the first workpiece and the second workpiece are curved surfaces of the same shape, and the first workpiece and the second workpiece are both made of transparent materials, the vacuum assembly equipment also includes a second shooting component 920, which is used to shoot the first workpiece and the second workpiece at the assembly station, wherein, in combination with Figure 6 As shown, the second shooting assembly 920 includes at least three groups of laser detection mechanisms, each of which includes a light-emitting component 921 and a receiving component 922 that are relatively arranged. The light-emitting component 921 and the receiving component 922 are both slidably arranged on the frame 100 along the second direction, and are used to detect the top surface outer contour of the first workpiece and the bottom surface outer contour of the second workpiece. Exemplarily, the second shooting assembly 920 includes three groups of laser detection mechanisms, and the light-emitting components 921 and receiving components 922 in the laser detection mechanisms in two groups are arranged relatively along the first direction, and are respectively arranged on both sides of the second guide rail 830 to avoid the transmission of the assembled vehicle 200; the light-emitting components 921 in another group of laser detection mechanisms are located in the extension direction of the second guide rail 830, and the receiving components 922 are movably arranged on the frame 100, and can be moved to the top of the second guide rail 830 to face the light-emitting components 921, and can be moved to the side of the second guide rail 830 to avoid the assembled vehicle 200; that is, the receiving components 922 in another group of laser detection mechanisms can move both in the second direction and in the first direction.

[0073] Specifically, in order to detect the first workpiece and the second workpiece, the second shooting assembly 920 includes a first lifting member 923, a second lifting member 924, a third lifting member 925 and a fourth lifting member 926, wherein the first lifting member 923 and the second lifting member 924 are arranged correspondingly, the third lifting member 925 and the fourth lifting member 926 are arranged correspondingly, the output end of the first lifting member 923 can be lifted and lowered in a vertical direction, and two light-emitting members 921 are installed, the output end of the second lifting member 924 can be lifted and lowered in a vertical direction and two receiving members 922 are installed, and the two light-emitting members 921 and the two receiving members 922 are arranged oppositely; the third lifting member 925 is located in the extension direction of the second guide rail 830, and its output end can be lifted and lowered in a vertical direction, and a light-emitting member 921 is installed, the output end of the fourth lifting member 926 can be lifted and lowered in a vertical direction and a receiving member 922 is installed, and the light-emitting member 921 and the receiving member 922 are arranged oppositely. Furthermore, the horizontal moving member 927 is disposed on the frame 100 , and an output end thereof can move along the first direction. The fourth lifting member 926 is disposed at the output end of the horizontal moving member 927 .

[0074] When in use, the second workpiece needs to be placed above the first workpiece, and the spacing between the two is a preset value. At this time, the outer contours of the two adjacent surfaces of the two workpieces are detected by the second shooting component 920 to determine whether the two are relatively parallel. If they are parallel, the second workpiece and the first workpiece can be fitted by lowering the second workpiece. If they are not parallel, the position and angle of the first workpiece are adjusted by the seven-axis adjustment mechanism at the bottom of the first workpiece, and then the second workpiece is lowered. Among them, the contour of the second workpiece is first measured by the light-emitting member 921 and the receiving member 922, and the contour of the first workpiece is measured after the light-emitting member 921 and the receiving member 922 are lowered. The measurement principle is roughly that the light-emitting member 921 and the receiving member 922 gradually descend, and the receiving member 922 can receive the light emitted by the corresponding light-emitting member 921, and the intensity changes, which means that the light-emitting member 921 and the receiving member 922 have not moved to the bottom of the second workpiece. When the intensity of the light is the same as the intensity of the light emitted by the light-emitting member 921, it means that the light-emitting member 921 and the receiving member 922 have moved to the bottom of the second workpiece, and a lowest point of the second workpiece is obtained.

[0075] Among them, the second workpiece is a curved surface structure. For ease of understanding, the second workpiece can be defined as a hemispherical surface, and it is an upper hemisphere, convex upward. The light of the light emitting component 921 will produce reflection and / or refraction when passing through the second workpiece, resulting in a change in the light intensity received by the receiving component 922. When the second workpiece is not tilted, the light emitting component 921 has not dropped below the second workpiece, and the light passes through the two side walls of the second workpiece; when the second workpiece is tilted, the light emitting component 921 has not dropped below the second workpiece, and the light passes through one side wall of the second workpiece. Since the concave and convex surfaces have different refractive indices for light, the tilt direction of the second workpiece can be determined. In summary, it is possible to determine whether the second workpiece is tilted, the tilt direction, and the degree of tilt.

[0076] Regarding the first workpiece and the second workpiece being parallel, it can be understood that a plurality of straight lines extending along the second direction form a plurality of first intersections and a plurality of second intersections on the first workpiece and the second workpiece respectively, and the distances between the first intersections and the second intersections on each straight line are equal.

[0077] In some embodiments, the vacuum assembly equipment also includes a third shooting component 930, which is disposed on the frame 100 and is located on the path where the second workpiece is transferred from the loading station to the assembly station. When the second workpiece is picked up, it is photographed by the third shooting component 930 during the process of moving to the assembly station to ensure that the picking is successful and whether the relative position relationship with the picking part 500 is correct.

[0078] The output end of the third shooting component 930 can move back and forth along the second direction, and can be raised to shoot the second workpiece, or lowered to avoid the moving second workpiece.
