Description

Technical Field

[0001] This invention relates to the field of projector equipment, and more specifically, to a process for manufacturing a stepper regulator. Background Technology

[0002] A projector, also known as a projector, is a device that projects images or videos onto a screen. It can be connected to computers, VCD players, DVD players, Blu-ray players, game consoles, DV players, etc., through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. Depending on their operating method, there are different types such as CRT, LCD, and DLP. The stepper is an important component in a projector. Currently, the stepper in projectors on the market contains a small number of blades and does not have efficient and accurate projection effects. Therefore, there is an urgent need for a high-precision stepper and its manufacturing process. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a process flow for manufacturing a stepper regulator.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a manufacturing process for a stepper regulator, comprising the following steps: S1, a fixed base assembly process, including the following steps,

[0005] Step S10, blade assembly process: The blades are assembled into the first blade assembly fixture to form a blade assembly body;

[0006] Step S11, Fixing seat assembly process: The fixing seat assembly is inserted into the second blade assembly fixture to form the fixing seat assembly;

[0007] Step S12, cover plate locking process: the first blade assembly fixture and the second blade assembly fixture are locked together, and the blade assembly and the fixed seat assembly are assembled and installed to form the cover plate assembly.

[0008] Step S13: Fixed cover assembly process, the fixed cover assembly is assembled into the cover plate assembly to form an assembly;

[0009] S2. Final assembly and testing engineering, including the following procedures:

[0010] Step S20, FPC assembly and welding process: The motor assembly is placed into the welding fixture, and the FPC assembly is placed on the motor to form the motor assembly.

[0011] Step S21, Motor assembly and locking process: The motor assembly is placed on the assembly body to form the finished product;

[0012] Step S22, Characteristic Inspection and Packaging Process: The finished product is inspected for characteristics. After the finished product is found to be without defects, it is packaged and sealed.

[0013] The present invention is further configured such that: a first positioning post and a second positioning post are provided on the blade, and the first positioning post and the second positioning post are located on opposite sides of the blade.

[0014] The present invention is further configured such that: a first positioning hole is provided on the first blade assembly fixture, the first positioning hole is adapted to the first positioning post and is used to limit the blade.

[0015] The present invention is further configured such that: a second positioning hole is provided on the fixing seat, and the fixing seat is fixed to the second blade assembly fixture through the second positioning hole.

[0016] The present invention is further configured such that the fixing cover is fixed to the cover plate assembly by screws.

[0017] The invention is further configured such that: the first blade assembly fixture has 3 slots for holding blades, the second blade assembly fixture has 3 slots for holding fixing seats, and the welding fixture has 5 slots for holding motors.

[0018] The invention is further configured such that the motor assembly is fixedly mounted on the assembly body by screws.

[0019] The present invention is further configured such that: there are 8 blades, and the blades are evenly arranged on the first blade group into the fixture.

[0020] By adopting the above technical solution, the blade is fixedly installed in the first positioning hole on the first blade assembly fixture by the first positioning post. The blade can make a circular motion with the first positioning post as the axis. A total of 8 blades are set. The tail of the next blade presses down on the head of the previous blade. The 8 blades are stacked in a circle in sequence. The assembly method of the fixture limit design solves the assembly difficulty and improves the production efficiency.

[0021] When processing the assemblies in the welding fixture and the blade assembly fixture, the waste of motion can be reduced. That is, the assemblies do not need to be repeatedly taken out of the blade assembly fixture and put into the final assembly fixture, which can improve the product flow efficiency. During the product transfer process, the use of fixtures to help flip the products solves the problem of blades being easily scattered during the transfer process, ensuring the quality of the blade assembly process, improving the efficiency of important actions in the cover plate assembly process, reducing the frequency of the final assembly fixture transfer after the combination, increasing the actual working time of the assembly process, and improving efficiency.

[0022] Designing the FPC assembly and welding process before the motor assembly reduces the difficulty of the operator's work during FPC assembly and welding, reduces the overall thickness of the welding fixture, facilitates the transfer of the welding fixture, and thus reduces costs. The stepper regulator requires no oil stains and high-temperature volatile substances during processing and manufacturing. The FPC assembly and welding process is carried out after the motor assembly to ensure that the combustion aid in the solder wire will not splash onto the product surface during welding.

[0023] Combining the characteristic testing and packaging processes ensures that the special step regulator products can be tested directly on the fixture, reducing product turnover and improving testing efficiency. After testing, the tester can directly place the product in the packaging box, which allows for reasonable scheduling of employee work time and improves labor efficiency. Attached Figure Description

[0025] Reference Figure 1 The process flow for manufacturing a stepper regulator according to the present invention will be further described.

[0026] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0028] A manufacturing process for a stepper regulator includes the following steps: S1, mounting the fixing base, which includes the following steps...

[0029] Step S10, blade assembly process: The blades are assembled into the first blade assembly fixture to form a blade assembly body;

[0030] Step S11, Fixing seat assembly process: The fixing seat assembly is inserted into the second blade assembly fixture to form the fixing seat assembly;

[0031] Step S12, cover plate locking process: the first blade assembly fixture and the second blade assembly fixture are locked together, and the blade assembly and the fixed seat assembly are assembled and installed to form the cover plate assembly.

[0032] Step S13: Fixed cover assembly process, the fixed cover assembly is assembled into the cover plate assembly to form an assembly;

[0033] S2. Final assembly and testing engineering, including the following procedures:

[0034] Step S20, FPC assembly and welding process: The motor assembly is placed into the welding fixture, and the FPC assembly is placed on the motor to form the motor assembly.

[0035] Step S21, Motor assembly and locking process: The motor assembly is placed on the assembly body to form the finished product;

[0036] Step S22, Characteristic Inspection and Packaging Process: The finished product is inspected for characteristics. After the finished product is found to be without defects, it is packaged and sealed.

[0037] In step S1, the blade is configured as a circular ring, with a first positioning post and a second positioning post on the blade. The first and second positioning posts are located on opposite sides of the blade and at both ends. The first blade assembly fixture is configured as a rectangular platform with three mounting slots. Each slot contains a mounting platform, and each mounting platform has eight first positioning holes for blade installation. The first positioning posts are adapted to the first positioning holes, and the blade is installed on the first positioning holes via the first positioning posts. A magnet is also provided on the blade, which can rotate in a circle around the first fixed post. When the blade rotates, the light transmission can be adjusted in steps. In step S10, the blade assembly is installed in the fixture. The sequential design facilitates blade assembly. During blade assembly, the tail of the next blade overlaps the head of the previous blade, and the eight blades are stacked in a circle. Simultaneously, the assembly process using the first blade assembly fixture design solves the assembly difficulty and improves production efficiency. It is estimated that without using the first blade assembly fixture, assembling blades directly on the product takes approximately 20 minutes per piece, while using the first blade assembly fixture takes approximately 2 minutes per piece, increasing production efficiency by nearly 90%. In step S11, the fixture assembly process design facilitates fixture assembly. The second blade assembly fixture is a rectangular platform with three slots for mounting fixtures. Each slot contains an installation platform, and each installation platform has a second positioning hole for mounting the fixing seat. The fixing seat also has a second positioning hole. This process allows for batch assembly of fixing seats. In step S12, the fixing cover assembly process facilitates the assembly of the assembly. The first blade assembly fixture and the second blade assembly fixture are interlocked, so that the blade assembly and the fixing seat assembly are installed to form a cover plate assembly. The fixing cover is then fixed to the cover plate assembly with screws to form the assembly. In step S1, the fixing seat assembly process uses the first blade assembly fixture and the second blade assembly fixture to assemble the blade into the fixing seat assembly. Only a 180° rotation is needed to assemble the blade into the fixing seat assembly. The blade assembly fixture is fastened to the second blade assembly fixture. This process reduces wasted motion, as the product does not need to be repeatedly removed from the blade assembly fixture and placed into the final assembly fixture, improving product flow efficiency. Simultaneously, the fixture's rotation during product transfer solves the problem of blades easily scattering, ensuring the quality of the blade assembly process and improving the efficiency of critical actions in the cover plate assembly process. By manually controlling the blade assembly fixture's movement within the process flow of fixing the cover assembly and the cover plate assembly, the process demonstrates reasonable and excellent performance in terms of working seconds. Using this process to manufacture assemblies reduces the frequency of blade assembly fixture movement, increases the actual working time of the assembly process, and improves efficiency.

[0038] In step S2, during the final assembly and inspection process, the welding fixture is set as a rectangular platform with five mounting slots. Each slot is used to assemble and store the motor, and the slot is designed to fit the motor. After the motor is placed in the slot, the PFC (Plug-in Components) is assembled and welded onto the motor. Designing the FPC welding process before the overall motor assembly ensures lower operator difficulty during welding, reduces the overall thickness of the welding fixture, facilitates fixture transfer, and lowers costs. Furthermore, when welding the FPC to the motor, the product must be free of oil and high-temperature volatile substances. Performing the welding process before motor assembly allows for… This invention ensures that the flux inside the solder wire will not splatter onto the product surface during soldering, and that there will be no quality issues due to incomplete wiping during the final cleaning process. Combining the characteristic testing and packaging processes allows products to be tested directly on the soldering fixture. In the industry, testing typically requires placing products on a specific testing platform, increasing product turnover. This invention's process allows products to be tested in real-time as they move along with the soldering fixture, reducing the time spent on product turnover and thus improving testing efficiency. After testing, the tester can directly place the product in the packaging box, allowing for more efficient scheduling of employee work time and improving labor productivity.
