[0029] The present invention provides a camera module bonding device. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further details the present invention with reference to embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Please refer toFigures 1 to 13 , the present invention provides a camera module bonding device. The "first", "second" and "third" purposes described herein are only for convenience of description and do not limit the present invention. For ease of understanding, Figure 2 , the X direction and the Y direction are schematically drawn. The conveyor belt runs along the X direction, the pallet reciprocates along the X direction, and the first slide seat reciprocates along the Y direction.

[0031] First, please refer to Figures 1 to 6 and Figure 10 , the camera module bonding device includes a chassis 90, an imaging board loading device 1, a dispensing mechanism 2, a lens loading device 5 and a lens transfer device 4 arranged on the chassis. The imaging board loading device 1 includes a sorting mechanism and a conveying mechanism. The sorting mechanism includes a bracket 111, a support plate 112 that can move vertically relative to the bracket, a magazine 12 arranged on the support plate, and a horizontally arranged feeding cylinder 13; the conveying mechanism includes a frame 16, conveyor belts (including 171 and 172) are respectively arranged on both sides of the frame, an adsorption plate 18 is arranged in the middle of the frame, a plurality of adsorption holes are arranged on the upper surface of the adsorption plate, and a lifting cylinder (not visible in the perspective of the attached drawing) is arranged at the bottom of the adsorption plate; the lens transfer device includes a gantry 410, a first linear slide rail 411, a first slider (not visible in the perspective of the attached drawing), a first slide seat 421 and a first driving device for driving the first slide seat to reciprocate are arranged on the gantry. An installation frame 422 is slidably connected to the first slide seat, and a first motor 423 for driving the installation frame to move up and down is arranged on the first slide seat; a second motor 424 is arranged downward on the installation frame, and a suction nozzle 429 is connected to the bottom of the main shaft of the second motor. Preferably, two first linear slide rails 411 are arranged on the gantry, each linear slide rail is respectively connected with a first slider, and the first slide seat is connected with the first slider. Preferably, the above-mentioned dispensing mechanism 20 is provided with two dispensing heads 21 (as Figure 3 shown), which improves work efficiency. Since dispensing itself is a prior art and not the inventive point of the present invention, components such as the dispensing head will not be elaborated here. The above-mentioned lens loading device 5 includes a substrate 50, a loading plate 51 slidably connected to the substrate, and a pallet driving device 52 for driving the pallet to move linearly. The pallet driving device is preferably a screw motor, and the pallet is driven to move by means of screw transmission.

[0032] In practical applications, a plurality of horizontal grooves 120 are arranged in the magazine 12 from top to bottom, and each horizontal groove can place a tray. The support plate and the bracket can be slidably connected by means of linear bearings and linear slide rails, and the support plate moves up and down through a motor 119 (as Figure 5 shown) and screw transmission. Linear bearings, linear slide rails and screw transmission are prior arts in themselves and will not be elaborated here.

[0033] As Figure 8 and Figure 9 shown, in order to further improve the feeding efficiency of the imaging plate, two bins 12 are provided in the bin-dividing mechanism. The two bins are arranged on the pallet, and the pallet is slidably connected to the support plate. In practical applications, the pallet and the support plate can be slidably connected by means of linear bearings and linear sliding rails, and the horizontal movement of the pallet is realized by the motor and the lead screw drive, so that one of the bins corresponds to the feeding cylinder. This setting facilitates that there is always one bin for normal feeding, and after the trays in the other bin are transported, the bin filled with trays can be replaced to ensure the continuity of production.

[0034] Preferably, a stopper 141 is respectively arranged on the inner side of the pallet corresponding to each bin ( Figure 9 only 1 stopper 141 can be observed from a certain perspective), and a pressing cylinder 142 is respectively arranged on the outer side of the pallet corresponding to each bin. During normal use, the piston rod of the pressing cylinder extends and presses against the side wall of the bin. When the bin needs to be replaced, the piston rod of the pressing cylinder retracts.

[0035] As Figure 7 shown, further, the conveyor belt includes a loading belt 171 and an unloading belt 172 ( Figure 7 only the loading belt 171 and the unloading belt 172 are observed on one side of the frame from a certain perspective. In fact, the loading belt 171 and the unloading belt 172 are respectively arranged on both sides of the frame). That is, the loading belt is located upstream of the unloading belt, and the loading belt and the unloading belt are respectively driven by corresponding motors (178 and 179). This setting enables the transportation and output of the trays to not interfere with each other. During use, when the imaging plate in the tray is completed with dispensing, the tray is transported to the unloading belt, where the lens assembly of the camera and the imaging plate are bonded. After the bonding is completed, the tray is further output to the downstream process. In practical applications, a tray recycling mechanism 91 can be arranged at the outlet end of the conveying mechanism to recycle the trays, which is not limited here.

[0036] Preferably, the frame of the conveying mechanism includes a fixed frame 161 and a moving frame 162, and the moving frame is slidably arranged on a flat plate 160. The moving frame and the flat plate are slidably connected by means of a linear sliding rail 163 (as Figure 6 and Figure 7 shown) and a linear bearing (not observable in the attached drawings), which facilitates adjusting the distance between the moving frame and the fixed frame to adapt to trays of different widths during actual use.

[0037] Please refer to Figures 10 to 12, Further, a top frame 420 is provided on the gantry 410. A second sliding seat and a second linear slide rail 431 are provided on the top frame. The second linear slide rail is connected to a second slider (not visible from the perspective of the attached drawing). The second sliding seat is connected to the second slider. A second driving device for driving the second sliding seat to reciprocate is provided on the top frame; a first CCD photographing and positioning assembly 71 is provided on the second sliding seat 441, and a second CCD photographing and positioning assembly 72 is provided on the bottom frame. This setting facilitates the first photographing and positioning assembly to take a photo and position the sucked lens downward after the suction nozzle sucks the lens. When the lens moves above the second CCD photographing and positioning assembly, the second CCD photographing and positioning assembly takes a photo of the lens upward, facilitating the second motor to rotate and adjust the posture of the lens, and improving the fitting effect.

[0038] As Figure 13 shown, two third linear slide rails 426 are vertically provided on the first sliding seat 421. Each third linear slide rail is respectively connected to a third slider 427, and the mounting bracket 422 is connected to the third slider 427. By providing the third linear slide rail and the third slider, it plays a guiding role in the up and down movement of the first bracket.

[0039] Further, the second motor 424 is connected to a first lead screw (not visible from the perspective of the attached drawing), and the lead screw nut corresponding to the first lead screw is connected to the mounting bracket. That is, in actual operation, the stable up and down movement of the mounting bracket is realized by means of lead screw transmission.

[0040] Preferably, the first driving device is a linear motor, and the first sliding seat is connected to the mover of the linear motor, ensuring that the first sliding seat can reciprocate quickly and stably, which is beneficial to further improving the transfer efficiency of the lens.

[0041] Preferably, the second driving device includes a second lead screw motor and a second lead screw (not visible from the perspective of the attached drawing), and the lead screw nut corresponding to the second lead screw is connected to the second sliding seat. In addition, other methods (such as gear and rack transmission, etc.) can also be used to realize the linear movement of the second sliding seat.

[0042] Further, a cantilever frame 30 is provided on the frame. A third sliding seat and a third driving device for driving the third sliding seat to reciprocate are provided on the cantilever frame. A third CCD photographing and positioning assembly (not shown in the figure) is provided on the third sliding seat. This setting facilitates the third CCD photographing and positioning assembly to take a photo downward and position the imaging plate after the tray containing the completed-dotted imaging plate reaches the fitting station, which is beneficial to improving the fitting accuracy between the lens and the imaging plate. The above-mentioned third sliding seat can realize linear reciprocating movement in the same way as the first sliding seat, so the structure of the third sliding seat and the third driving device is not specifically drawn in the attached drawing.

[0043] For ease of understanding, the working principle is briefly described as follows:

[0044] (1) Multiple trays (not shown in the figure) are placed from top to bottom in each bin, and multiple imaging plates of cameras to be processed are respectively placed in each tray (not shown in the figure). (2) Each time the piston rod of the feeding cylinder expands and contracts, one tray in the bin is pushed onto the feeding belt; the support plate rises by a certain height so that the next tray is aligned with the piston rod of the feeding cylinder. (3) After the tray with the imaging plate reaches the feeding belt, it is conveyed above the suction plate. The lifting cylinder drives the suction plate to rise, and the tray is sucked by the suction plate, facilitating dispensing on the imaging plate in the tray. After dispensing is completed, the suction plate descends, and the tray contacts the feeding belt. (4) The tray with the imaging plate moves along with the discharging belt and is output to the bonding station. The third CCD camera positioning assembly takes a downward photo to position the imaging plate. (6) The tray with multiple lenses is placed on the loading plate of the lens loading device. The pallet driving device drives the pallet to move under the mounting frame. The mounting frame descends. After the suction nozzle sucks one lens, the mounting frame rises. (7) The first CCD camera positioning assembly takes a downward photo to position the sucked lens assembly. The first driving device drives the first sliding seat to move horizontally above the second CCD camera positioning assembly. The second CCD camera assembly takes an upward photo to position the sucked lens. (8) The first driving device drives the first sliding seat to move horizontally to the bonding station. The second motor rotates to adjust the posture of the lens. After the lens is bonded, the suction nozzle disconnects the vacuum, and the mounting frame rises; the first sliding seat resets. (9) After all the imaging plates in the tray are completed with lens bonding, the discharging belt further outputs the tray with the camera module.

[0045] Through the above analysis, it can be seen that compared with the prior art, the camera module bonding device provided by the present invention integrates components such as an imaging plate loading device, a dispensing mechanism, a lens loading device, and a lens transfer device on the chassis, realizing automatic conveyance of the imaging plate of the camera module to be bonded, dispensing on the imaging plate, automatically loading, transferring, and bonding the lens onto the imaged plate after dispensing, making the bonding of the imaging plate and the lens of the camera module more convenient and greatly improving the bonding effect.

[0046] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
