Due to the design requirements, the panel body is a structure with a certain curvature, the back of the panel body is a curved surface and is not light-transmitting, and the front of the panel body adopts a white appearance, and is matched with white lights of light-emitting elements such as digital tubes. However, when manual alignment and lamination operations are currently used, it is easy for light-emitting elements such as digital tubes to be misaligned with light-transmitting through holes and light-transmitting areas, resulting in poor display such as blurred display, halo, shading, and light leakage. Therefore, it is necessary to solve the above problems through automated equipment. Utility Model Content

The backlight display module 93 is attached to the back of the panel body 91 through the light-isolating sponge layer 92. The back of the panel body 91 is a curved surface and is opaque. The backlight display module 93 has a digital tube 100 forming the number 8. The light-isolating sponge layer 92 has a light-transmitting through hole 200 corresponding to the shape of the digital tube. The panel body 91 has a light-transmitting area 300 corresponding to the shape of the digital tube. The area of ​​the digital tube is larger than the area of ​​the light-transmitting through hole, and the area of ​​the light-transmitting through hole is larger than the area of ​​the light-transmitting area. The correlation between the digital tube 100, the light-transmitting through hole 200 and the light-transmitting area 300 can be referred to. Figure 1 The dotted line in the outer circle shows the outline of the digital tube, the solid line in the middle shows the outline of the light-transmitting hole, and the dotted line in the inner circle shows the outline of the light-transmitting area.

[0027] The utility model provides a positioning laminating machine for processing the front control panel of a drum washing machine, such as Figures 2 to 5As shown, it includes a frame 1 and a control center arranged on the frame 1, a lower fixture 2, an upper fixture 3 and a CCD visual alignment component 4. The lower fixture 2 is used to position the light-isolating sponge layer 92 or the panel body 91. The lower fixture 2 is fixed on the micro-motion platform 5. The micro-motion platform 5 can generally be fine-tuned on the X-axis and the Y-axis, and can also be rotated at an angle, so as to adjust the parts on the micro-motion platform 5 to the correct position. The control center controls the micro-motion platform 5 to adjust the position according to the alignment information of the backlight display module 93 and the light-isolating sponge layer 92 or the alignment information of the backlight display module 93 and the panel body 91 obtained by the CCD visual alignment component 4. The upper fixture 3 is located above the lower fixture 2. The upper fixture 3 is connected to the lifting component 6. The lifting component 6 drives the upper fixture 3 downward, so that the backlight display module 93 is attached to the light-isolating sponge layer 92 moved into place or the backlight display module 93 attached with the light-isolating sponge layer 92 is attached to the panel body 91 moved into place. Figure 2 and Figure 3 In order to show the panel body 91 and the light-isolating sponge layer 92, both are drawn out.

[0028] Since the digital tube forming the figure-8 structure has both horizontal and vertical edges and sharp corners, after the CCD visual alignment component 4 captures the relevant point-line-angle structure, the position deviation of the light-isolating sponge layer 92 relative to the backlight display module 93 can be accurately obtained and the position of the light-isolating sponge layer 92 can be adjusted according to the position deviation, so that the end of the light-transmitting through hole can be aligned with the sharp corner of the digital tube 100, and the long side of the light-transmitting through hole can be parallel to the long side of the digital tube 100, ensuring that after the backlight display module 93 is bonded to the light-isolating sponge layer 92, the alignment accuracy between all light-emitting elements on the backlight display module 93 and the corresponding light-transmitting through holes on the light-isolating sponge layer 92 can meet the requirements. In the same way, the position deviation of the panel body 91 relative to the light-isolating sponge layer 92 is obtained by comparison through the CCD vision alignment component 4, and the position of the panel body 91 is adjusted according to the position deviation, so that the end of the light-transmitting area is aligned with the end of the light-transmitting through hole, and the long side of the light-transmitting area is parallel to the long side of the light-transmitting through hole, to ensure that after the light-isolating sponge layer 92 is bonded to the panel body 91, the alignment accuracy between all light-emitting elements on the backlight display module 93 and the corresponding light-transmitting areas on the panel body 91 can meet the requirements, thereby improving the alignment accuracy of light-emitting elements such as the digital tube 100 and the light-transmitting through holes and light-transmitting areas, effectively avoiding poor display, greatly improving the display effect, and achieving continuous repeated bonding, thereby improving the production capacity and operating efficiency of the whole machine, and the consistency of repeated bonding is high, thereby improving the stability of product appearance.

[0029] Since the light-isolating sponge layer 92 and the panel body 91 have different sizes, in order to allow the lower jig 2 to be reused for positioning the light-isolating sponge layer 92 and the panel body 91, a lower positioning groove 21 can be provided on the lower jig 2. The lower positioning groove 21 is in the shape of a long strip extending laterally. One end of the lower positioning groove 21 in the length direction is open so that a part of the panel body 91 can extend out of the lower positioning groove 21, and the other end of the lower positioning groove 21 in the length direction is closed and used to position the light-isolating sponge layer 92 and the panel body 91. When it is necessary to position the light-isolating sponge layer 92, the light-isolating sponge layer 92 is relatively small in size and can be placed in the lower positioning groove 21 as a whole, and fits with the corner of the closed end of the lower positioning groove 21 through a corner, a long side of the light-isolating sponge layer 92 fits with a transversely extending side of the lower positioning groove 21, and a wide side of the light-isolating sponge layer 92 fits with the side of the closed end of the lower positioning groove 21. When it is necessary to position the panel body 91, the length of the panel body 91 is relatively long, and a part of the panel body 91 will extend from the open end of the lower positioning groove 21. The side of the end of the panel body 91 located in the lower positioning groove 21 fits with the side of the closed end of the lower positioning groove 21, and the two long sides of the panel cup body can fit with the two transversely extending sides of the lower positioning groove 21, thereby realizing the positioning function of the light-isolating sponge layer 92 and the panel body 91 by multiplexing a lower positioning groove 21. One side of the lower positioning groove 21 in the width direction is also open, forming a semi-open right-angle structure.

[0030] In one embodiment, the lifting assembly 6 includes a lifting cylinder 61 and a connecting plate 62 fixed to the output end of the lifting cylinder 61, and the upper fixture 3 is elastically connected to the connecting plate 62. The lifting assembly 6 can also use other common lifting mechanisms such as linear motors. The upper fixture 3 is elastically connected to the connecting plate 62, which can prevent the backlight display module 93 and the panel body 91 from being crushed during the bonding process.

[0031] In order to improve the stability of the lifting movement of the upper fixture 3, a guide rod 32 can be fixed on the upper fixture 3, the guide rod 32 vertically penetrates the connecting plate 62 and slides vertically relative to the connecting plate 62, and the elastic member 33 is sleeved on the guide rod 32 and is located between the upper fixture 3 and the connecting plate 62 to maintain a compressed state. Through the guidance of the guide rod 32, the stability of the vertical movement of the upper fixture 3 can be ensured, and there will be no tilting or jamming. The elastic member 33 can generally use common parts such as cylindrical springs. In order to further improve the stability of the lifting movement of the upper fixture 3, a guide seat 63 is provided on the upper surface of the connecting plate 62, and the guide rod 32 passes through the guide seat 63. A limiter 34 is provided at the top of the guide rod 32, and the limiter 34 is against the top surface of the guide seat 63 to prevent the guide rod 32 from detaching from the connecting plate 62. The limiter 34 can be connected to all the guide rods 32 using a plate body, and the lifting cylinder 61 can be fixed on the limiter 34. The limiter 34 can also use common nuts, shaft retaining rings and other parts. Compared with the connecting plate 62 , the guide seat 63 can increase the contact length with the guide rod 32 , increase the stability of the movement of the guide rod 32 , and further ensure the stability of the vertical movement of the upper fixture 3 .

[0032] In order to facilitate the absorption of the backlight display module 93, a vacuum absorption method can be adopted. Specifically, a fixing bracket 35 is provided on the back of the upper jig 3. The upper jig 3 is provided with a suction cup 36 for absorbing the backlight display module 93. The suction cup 36 includes a flexible disc 361 and a connector 362. The flexible disc 361 is located on the front of the upper jig 3. The connector 362 is connected to the back of the flexible disc 361 and passes through the upper jig 3 to be fixed to the fixing bracket 35. Since the thickness of the upper jig 3 is relatively small, adding a fixing bracket 35 to fix the connector 362 can increase the reliability of the fixation of the suction cup 36 and ensure that the suction cup 36 still maintains a good absorption effect after long-term use. The connector 362 is easy to plug into the trachea and is easy to assemble.

[0033] In order to avoid the connection plate 62 being too far away from the upper fixture 3, which causes the guide rod 32 to be too long and affects the stability of the lifting movement of the upper fixture 3, a avoidance through hole 621 can be provided on the connection plate 62, and the air pipe 7 passes through the avoidance through hole 621 to connect with the connector 362, or the connector 362 extends into the avoidance through hole 621 to connect with the air pipe. The connector 362 will not be blocked by the connection plate 62, which facilitates the connection of the air pipe 7 with the connector 362, and does not affect the lifting movement of the upper fixture 3.

[0034] Considering that the bottom surface of the upper jig 3 is not easy to observe and workers need to operate blindly, an upper positioning rib 37 for positioning the backlight display module 93 can be provided on the bottom surface of the upper jig 3. The backlight display module 93 is pressed against the upper positioning rib 37 to achieve positioning, and there is no need to watch while doing it, which is more convenient for practical operation. Since the backlight display module 93 is basically a rectangular parallelepiped structure, the upper positioning rib 37 can be designed to include a transverse rib 371 and a longitudinal rib 372. The long side of the backlight display module 93 is pressed against the transverse rib 371 for positioning, and the wide side of the backlight display module 93 is pressed against the longitudinal rib 372 for positioning. Workers can know by feel that the backlight display module 93 is accurately fixed to the upper jig 3. The transverse rib 371 and the longitudinal rib 372 can adopt a columnar structure, and a plurality of them are arranged horizontally and longitudinally along a straight line, respectively. The transverse ribs 371 and the longitudinal ribs 372 may also be designed to be strip-shaped and connected to form a right-angle structure, or they may be separately arranged to shorten the lengths of the transverse ribs 371 and the longitudinal ribs 372 while ensuring the reliability of the positioning of the backlight display module 93 .

[0035] In order to achieve a fool-proof effect when the backlight display module 93 is placed on the upper jig 3, a notch 31 for avoiding the wiring of the backlight display module 93 can be provided on the side of the upper jig 3. When the worker positions the backlight display module 93 on the upper jig 3, the wiring of the backlight display module 93 needs to pass through the notch 31 to accurately position the backlight display module 93 on the upper jig 3.

[0036] In one embodiment, the CCD visual alignment component 4 includes an upper camera, a lower camera and a light source, the upper camera is located above the lower fixture 2 and is used to take pictures of the parts on the lower fixture 2, and the lower camera is located below the upper fixture 3 and is used to take pictures of the parts on the upper fixture 3. The CCD visual alignment component 4 belongs to the prior art and will not be described in detail here.

[0037] In order to realize the production and processing of the front control panel of the drum washing machine, the above-mentioned alignment and lamination machine can work according to the following alignment and lamination method:

[0038] S1, fix the backlight display module 93 on the upper fixture 3, fix the light-isolating sponge layer 92 on the lower fixture 2, take the outer frame outline of the digital tube 100 as a reference, obtain the position deviation of the light-isolating sponge layer 92 relative to the backlight display module 93 by comparison through the CCD visual alignment technology, and adjust the position of the light-isolating sponge layer 92 according to the position deviation, so that the end of the light-transmitting through hole is aligned with the sharp corner of the digital tube 100, and the long side of the light-transmitting through hole is parallel to the long side of the digital tube 100;

[0039] S2, tear off the upper protective film of the light-isolating sponge layer 92, drive the upper fixture 3 downward, make the backlight display module 93 fit the light-isolating sponge layer 92, and then drive the backlight display module 93 and the light-isolating sponge layer 92 upward;

[0040] S3, fix the panel body 91 to the lower fixture 2, take the outer frame outline of the light-transmitting through hole as a reference, compare and obtain the position deviation of the panel body 91 relative to the light-isolating sponge layer 92 through CCD visual alignment technology, and adjust the position of the panel body 91 according to the position deviation, so that the end of the light-transmitting area is aligned with the end of the light-transmitting through hole, and the long side of the light-transmitting area is parallel to the long side of the light-transmitting through hole;

[0041] S4, tear off the lower protective film of the light-isolating sponge layer 92, drive the upper jig 3 downward to make the light-isolating sponge layer 92 fit with the panel body 91, release the backlight display module 93 from the upper jig 3, and remove the front control panel that has been fitted from the lower jig 2.

[0042] As a control requirement, in S1, the deviation of the end of the light-transmitting through hole and the sharp corner of the digital tube 100 is controlled within ±0.2mm, and the deviation of the long side of the light-transmitting through hole being parallel to the long side of the digital tube 100 is controlled within ±0.3mm. Ensuring the alignment accuracy can help to ensure the display effect. Similarly, in S3, the deviation of the end of the light-transmitting area and the end of the light-transmitting through hole is controlled within ±0.1mm, and the deviation of the long side of the light-transmitting area being parallel to the long side of the light-transmitting through hole is controlled within ±0.2mm. Ensuring the alignment accuracy can help to ensure the display effect.

[0043] In one embodiment, the light-isolating sponge layer 92 includes EVA foam, both sides of the foam are attached with double-sided adhesive, and the upper protective film and the lower protective film are light-colored separate PET films and covered with double-sided adhesive. The light-isolating sponge layer 92 generally adopts a dark color to ensure the light-isolating effect, such as black, which will also lead to insufficient light in the light-transmitting through hole. When taking pictures through the CCD visual alignment technology, the outer frame contour of the light-transmitting through hole is likely to be unclear, which is not conducive to comparing and obtaining position deviations. Therefore, the separate PET film is selected to be light-colored, such as white or beige, so that a high contrast is formed between the outer frame contour of the light-transmitting through hole and the inside of the light-transmitting through hole. Moreover, only after adjusting the position of the light-isolating sponge layer 92, the upper protective film of the light-isolating sponge layer 92 can be torn off to expose the double-sided adhesive on the upper surface for attachment. Similarly, only after adjusting the position of the panel body 91, the lower protective film of the light-isolating sponge layer 92 can be torn off to expose the double-sided adhesive on the lower surface for attachment, which is conducive to the CCD visual alignment technology to obtain accurate position information of the outer frame contour of the light-transmitting through hole.

[0044] In order to ensure the dimensional accuracy of the light-transmitting through hole, the light-isolating sponge layer 92 can be formed into the light-transmitting through hole by using laser engraving technology, and the dimensional accuracy of the light-transmitting through hole is controlled within ±0.1 mm.

[0045] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
