Description

Technical Field

[0001] This application relates to the field of tactile displays for the blind, and more particularly to an assembly apparatus and method for a Braille reader module. Background Technology

[0002] The Braille reader module includes a support housing, a top cover, multiple drive mechanisms, multiple eccentric wheels, and multiple contacts. The support housing includes a first end and a second end, and the top cover includes a first side and a second side. The number of drive mechanisms, eccentric wheels, and contacts is the same. The first end of the support housing has a first mounting groove for mounting the eccentric wheel, and the first end of the support housing has a second mounting groove for mounting the drive mechanism. The top cover has a through hole for the contacts to extend and retract. The first end of the support housing and the second side of the top cover are joined together to form the Braille reader module. One drive mechanism drives one eccentric wheel to rotate, controlling the large-diameter end or the small-diameter end of the eccentric wheel to abut the contact point, and simultaneously controls multiple drive mechanisms to realize the extension and retraction of the contacts. Currently, the assembly of each component of a Braille reader module is done manually. Personnel need to install and fix the drive mechanism inside a support housing, place an eccentric wheel inside the housing, and then stably place the support with the drive mechanism and eccentric wheel installed on a workbench to prevent the eccentric wheel from falling out. Finally, the top cover with the contacts is aligned and glued to the support housing to complete the assembly of one module. Then, the assembly of the next module begins. This manual assembly process allows only one person to assemble one module at a time, resulting in low assembly efficiency. Summary of the Invention

[0044] like Figures 1-3As shown, the Braille reader module includes a support housing 1, a top cover 2, multiple drive mechanisms 11, multiple eccentric wheels 12, and multiple contacts 21. The support housing 1 includes a first end 13 and a second end 14, and the top cover 2 includes a first side 24 and a second side 25, which are connected. The first end 13 of the support housing 1 and the second side 25 of the top cover 2 are aligned. The number of drive mechanisms 11, eccentric wheels 12, and contacts 21 is the same. The end face of the first end 13 of the support housing 1 is provided with a first mounting groove 15 for mounting the eccentric wheel 12. The eccentric wheel 12 is rotatably mounted on the first mounting groove 15. In this embodiment, the first mounting groove 15 is provided with a U-shaped groove 151 for rotatably connecting with the shaft of the eccentric wheel 12. The opening of the U-shaped groove 151 extends to the opening of the first mounting groove 15, and the shaft of the eccentric wheel 12 is placed in the U-shaped groove 151. The end face of the first end 13 of the support housing 1 is provided with a second mounting groove 16 for mounting the drive mechanism 11. The drive mechanism 11 is required to be fixed in the second mounting groove 16. The upper cover 2 is provided with a through hole 22 for the extension and retraction of the contact 21. The first end 13 of the support housing 1 is provided with a hot pressing column 18. The upper cover 2 is also provided with a glue hole 23 for the hot pressing column 18 to pass through. The hot pressing column 18 is required to form a fixed connection with the upper cover 2 to stabilize the connection between the upper cover 2 and the support housing 1. The second end 14 of the support housing 1 is provided with a second positioning column 17. The second positioning column 17 is used to cooperate with other components of the Braille reader to position and install the Braille reader module.

[0045] This application provides an assembly apparatus for a Braille reader module.

[0046] The assembly device includes:

[0047] like Figure 4 and Figure 5 As shown, the first fixture 3 has a first mating surface 31 on one side. The first mating surface 31 is provided with a plurality of first grooves 32. The bottom of the first grooves 32 is provided with a plurality of first positioning holes 33. The first grooves 32 are used to place the upper cover 2. The first side 24 of the upper cover 2 contacts the bottom of the first groove 32. When the upper cover 2 is located in the first groove 32, the plurality of through holes 22 and the plurality of first positioning holes 33 correspond one-to-one.

[0048] like Figures 6-9 As shown, the second fixture 4 has a second mating surface 41 on one side. The second mating surface 41 is provided with a plurality of second grooves 42. The second grooves 42 are used to place the support housing 1. The bottom of the second grooves 42 is used to contact the first end 13 or the second end 14 or the drive mechanism 11 of the support housing 1.

[0049] Among them, such as Figure 10 and Figure 11 As shown, after the first mating surface 31 of the first fixture 3 and the second mating surface 41 of the second fixture 4 are mated, the groove opening of the first groove 32 and the groove opening of the second groove 42 are mated, and the second side 25 of the upper cover 2 placed in the first groove 32 and the first end 13 of the support shell 1 placed in the second groove 42 are mated.

[0050] This application allows for the simultaneous placement of multiple support housings 1 onto a second fixture 4, enabling the batch installation of drive mechanisms 11 and eccentric wheels 12 within multiple support housings 1 on a single second fixture 4, thus improving the efficiency of batch assembly of drive mechanisms 11 and eccentric wheels 12 for Braille reader modules. Similarly, by placing multiple top covers 2 simultaneously onto a second fixture 4, the assembly of multiple contacts 21 and top covers 2 can be completed on a single first fixture 3, further improving the efficiency of batch assembly of top covers 21 and contacts 21 for Braille reader modules. Finally, an application is made to the contact 21 from the touched end, with the back facing the first concave... The force applied in the direction of the groove 32 causes the contact point 21 to abut against the first side 24 of the upper cover 2, and the upper cover 2 to abut against the bottom of the first groove 32. The first fixture 3 is flipped so that it is positioned above the second fixture 4, with the opening of the first groove 32 facing the opening of the second groove 42. The first groove 32 and the second groove 42 are aligned, and the first mating surface 31 of the first fixture 3 and the second mating surface 41 of the second fixture 4 are mated. The upper covers 2 and support housings 1 of multiple Braille reader modules are simultaneously combined, improving the assembly efficiency of the upper covers 2 and support housings 1 for batch Braille reader modules. Then, the upper covers 2 and support housings 1 are fixed as required.

[0051] In this application, the first grooves 32 are arranged in an array on the first fixture 3, and the second grooves 42 are also arranged in an array on the second fixture 4. The regular arrangement of the first grooves 32 and the second grooves 42 facilitates the sequential placement of the top cover 2, the support housing 1, the contact point 21, the drive mechanism 11, and the eccentric wheel 12, among other components. In this embodiment, the first fixture 3 may have 50 first grooves 32, and the number of second grooves 42 is the same as the number of first grooves 32. In other embodiments, this can be adjusted according to actual conditions.

[0052] In one embodiment, the force applied to the contact 21 can be applied by covering the side of the first fixture 3 facing away from the first mating surface 31 with a rubber membrane, and having the first positioning hole 33 pass through the first fixture 3. The rubber membrane has an opening corresponding to the first positioning hole 33. The rubber membrane can deform. In its natural state, the opening on the rubber membrane is smaller than the outer diameter of the contact 21. The thickness of the first fixture 3 needs to be set to ensure that when the contact 21 is installed on the upper cover 2, a downward force is applied to the contact 21. The contact 21 can pass through the through hole 22 and the first positioning hole 33 and then through the opening of the rubber membrane. The opening of the rubber membrane deforms under the downward force of the contact 21 to allow the contact 21 to pass through, and the opening of the rubber membrane forms a clamping force on the contact 21, thereby stabilizing the position of the contact 21 on the upper cover 2. After the first fixture 3 is flipped over and the first mating surface 31 faces downward, an upward pulling force is formed on the contact 21 and the upper cover 2, stabilizing the contact 21 and the upper cover 2 on the first fixture 3.

[0053] like Figure 10 As shown, in another embodiment, the force applied to the contact 21 can be as follows: the side of the first fixture 3 opposite to the first mating surface 31 is an adsorption surface, and an adsorption groove 34 is provided on the adsorption surface. The bottom of the adsorption groove 34 is penetrated by the first positioning hole 33. The adsorption groove 34 is used to connect to the air extraction device, and a negative pressure is formed in the adsorption groove 34, thereby adsorbing the contact 21 and the upper cover 2. After the first fixture 3 is flipped over and the first mating surface 31 faces down, the negative pressure in the adsorption groove 34 stabilizes the contact 21 and the upper cover 2 on the first fixture 3.

[0054] like Figure 10 As shown, the assembly device also includes at least two mating positioning pins 5 and at least two mating positioning holes. The mating positioning pins 5 are spaced apart on the first mating surface, and the mating positioning holes are spaced apart on the second fixture 4. When the mating positioning pins 5 pass through the mating positioning holes, the first groove 32 and the second groove 42 are aligned, thereby improving the alignment efficiency of the first groove 32 and the second groove 42.

[0055] like Figure 8 and Figure 9 As shown, the bottom of the groove of the second fixture 4 is provided with a second positioning hole 43. The second positioning hole 43 is used to cooperate with the second positioning post 17 on the support housing 1. The cooperation of the second positioning post 17 and the second positioning hole 43 is used to position the support housing 1 placed in the second groove 42. The contact point 21 positions the upper cover 2 in the first groove 32. The second positioning post 17 positions the support housing 1 in the second groove 42. When the first groove 32 and the second groove 42 are aligned, the accuracy of the alignment between the upper cover 2 and the support housing 1 is improved.

[0056] In one embodiment, two mating positioning pins 5 and two mating positioning holes are provided. The mating positioning pins 5 are located at different ends of the first fixture 3. The two mating positioning pins 5 are cylinders of the same size. One mating positioning hole is a circular hole 51 that fits with the mating positioning pin 5 with a clearance, and the other mating positioning hole is an oblong hole 52. The length direction of the oblong hole 52 is parallel to the line connecting the centers of the two mating positioning holes, and the inner diameter of the semicircular portion of the oblong hole 52 is the same as the inner diameter of the circular hole 51. One mating positioning pin 5 fits with the circular hole 51 with a clearance, and the other mating positioning pin 5 fits with the oblong hole 52. When separating the first fixture 3 and the second fixture 4, the oblong hole 52 provides more room for the mating positioning pin 5 located in the oblong hole 52. Combined with the clearance fit between the circular hole 51 and the mating positioning pin 5, the first fixture 3 can more easily tilt to one side relative to the second fixture 4 when separating, thus improving the separation efficiency of the first fixture 3 and the second fixture 4.

[0057] This application also provides a method for assembling a Braille reader module, which uses the above-mentioned assembly device to assemble the Braille reader module. The assembly method includes:

[0058] like Figure 6 and Figure 7 As shown, to install the drive mechanism 11: Place the second fixture 4 flat with the second mating surface 41 facing upwards. Place multiple support housings 1 sequentially into several second grooves 42 with their first ends 13 facing the second grooves 42. Correctly install the drive mechanism 11 into the second mounting slots 16 of the support housings 1, ensuring that each second mounting slot 16 contains a drive mechanism 11. The drive end of the drive mechanism 11 should pass through the opening at the bottom of the second mounting slot 16. Apply adhesive to all the second mounting slots 16 using a dispensing machine. After the adhesive cures, the drive mechanism 11 and the second mounting slots 16 are bonded together. Remove all the support housings 1 from the second grooves. Take out from 42. Specifically, correctly installing the drive mechanism 11 in the second mounting slot 16 of the support housing 1 means: In one embodiment, when the drive mechanism 11 is electromagnetically driven, one end of the drive mechanism 11 is provided with a protruding magnetic conductor for better driving the eccentric wheel 12 to rotate. The bottom of the first mounting slot 15 and the second mounting slot 16 are provided with openings for the magnetic conductor to pass through. Correct installation means that one end of the magnetic conductor passes through the opening. In other types of Braille reader modules, the correct installation of the drive mechanism 11 includes the drive end of the drive mechanism 11 facing the bottom of the second mounting slot 16, and ensuring the correctness of other orientation angles.

[0059] like Figure 7 and Figure 8As shown, the eccentric wheel 12 is installed as follows: the support housing 1 with the drive mechanism 11 attached is placed sequentially into several second grooves 42 with the second end 14 facing the second groove 42, and the eccentric wheel 12 is correctly installed in the first mounting groove 15 so that all the first mounting grooves 15 have the eccentric wheel 12; wherein, in this embodiment, the correct installation of the eccentric wheel 12 is that the rotating shaft of the eccentric wheel 12 is placed in the U-shaped groove 151. In other embodiments, the correct installation of the eccentric wheel 12 requires that the rotating shaft of the eccentric wheel 12 is connected to the rotating component on the support housing 1 to ensure that the eccentric wheel 12 can rotate normally.

[0060] like Figure 4 and Figure 5 As shown, install the contact 21; lay the first fixture 3 flat with the first mating surface 31 facing upward, and place multiple top covers 2 with the first side 24 facing the first groove 32 into several first grooves 32 in sequence, and pass the contact 21 through the through hole 22 of the top cover 2 and the first positioning hole 33 of the first groove 32, so that there is a contact 21 in each through hole 22.

[0061] like Figures 10-12 As shown, the upper cover 2 and the supporting housing 1 are assembled: A force is applied to the contact 21 from the touched end, in the direction opposite to the opening of the first groove 32, so that the contact 21 is stable in the upper cover 2 and the upper cover 2 is stable in the first groove 32. The first fixture 3 is flipped so that the first mating surface 31 faces down. The contact 21 and the upper cover 2 are still on the first fixture 3, so that the first fixture 3 is above the second fixture 4, and the opening of the first groove 32 faces the opening of the second groove 42. Align the first groove 32 and the second groove 42, and approach the first fixture 3 and the second fixture 4 so that the hot pressing column 18 on the first end 13 of the supporting housing 1 passes through the glue hole 23 on the upper cover 2. The force on the contact 21 is removed, the first fixture 3 is removed from the second fixture 4, and glue is applied to the glue hole 23 using a glue dispensing machine. After the glue cures, the hot pressing column 18 is bonded to the glue hole 23, thus completing the assembly of the upper cover 2 and the supporting housing 1.

[0062] After assembling the top cover 2 and the supporting housing 1, the Braille reader module is placed in a special fixture, the signal is connected, and the operation of the module contact 21 is tested. The tested Braille reader modules are then packaged, completing the production process.

[0063] In the step of installing the eccentric wheel 12, after completing the operation of sequentially placing the eccentric wheel 12 into the first mounting slot 15, a vision camera is used to take a picture, and the image obtained by the picture is detected to determine whether the eccentric wheel 12 is missing or incorrectly installed.

[0064] In the steps of installing the drive mechanism and assembling the top cover and the support housing, the adhesive is a high-temperature curing adhesive. The adhesive curing step includes: after applying the adhesive, placing the fixture containing the parts into a heating box for baking at a temperature of 80-100℃, and continuing to bake at 80-100℃ until the adhesive is cured. In specific implementation, the baking time can be 5-30 minutes, which can be adjusted according to the actual situation.

[0065] After removing the first fixture 3 and before applying glue to the glue hole 23, use a hot press to heat press the hot press column 18 on the top of the upper cover 2 so that the hot press column 18 deforms to better fit the glue hole 23.

[0066] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
