Description

Technical Field

[0001] This invention relates to the field of marine navigation, and more specifically to a surface alignment assembly system and method for a compass operating unit. Background Technology

[0002] A compass operating unit is a marine navigation product primarily used to display information such as the ship's position, heading, pitch, and roll, and to provide various alarm functions. The compass operating unit is typically installed in a prominent location in the ship's bridge for easy observation and operation by the crew.

[0003] Please see Figure 1 and Figure 2 The compass operating unit 100 typically includes a display screen 103, buttons 105, and indicator lights 106 for manual operation. The display screen 103, buttons 105, and indicator lights 106 are all installed inside the rear housing 104. The side of the rear housing facing the display screen 103, buttons 105, and indicator lights 106 has an opening to expose the display screen and buttons for easy operation. An aluminum panel 101 is detachably mounted on the side of the rear housing with the opening. The aluminum panel 101 also has openings corresponding to the display screen 103, buttons 105, and indicator lights 106 to expose the display screen and buttons for easy operation.

[0004] To further protect the display screen and buttons, an adhesive layer 102 is usually applied to the surface of the aluminum panel. The adhesive is generally placed on the back of the surface layer 102 to protect the aluminum panel and internal structure, while also serving an aesthetic purpose.

[0005] Because the market demand for compass operating units is limited and they are not consumables, they are not suitable for production using high-cost fully automated production lines. Therefore, in the production process, the assembly of the outermost surface layer is often done manually.

[0006] Please see Figure 2 The surface layer 102 also has display screen openings 107, button openings 108, and indicator light openings 109 corresponding to the display screen 103, button 105, and indicator light 106. Since the surface layer may be a hard film or a soft film, these openings increase the surface layer's susceptibility to deformation. In addition, the large number of button openings and the very small indicator light openings make it very difficult to assemble the surface layer correctly. This requires precise alignment of each hole during assembly while ensuring that the surface layer does not deform.

[0007] Therefore, if manual assembly is used, it is very easy for the positions of various openings to deviate, such as being too high, too low, too far to the left, or too far to the right. This not only increases assembly time and production costs but also leads to a higher product defect rate. In addition, improper assembly of the surface layer can seriously affect the appearance quality of the product, especially when the surface layer has strong adhesive properties. Once the assembly is not in place, it is difficult to readjust or re-attach, further increasing production difficulty and costs.

[0008] Therefore, designing an assembly system that can effectively improve surface assembly accuracy, reduce production costs, shorten assembly time, and reduce defect rate is of great significance for the production of compass operating units, so as to meet the needs of small-batch, high-quality production while taking into account the convenience of operation and cost factors. Summary of the Invention

[0009] The purpose of this invention is to provide a surface alignment assembly system and method for a compass operating unit, in order to solve the technical problem in the prior art that the surface of the compass operating unit often needs to be manually assembled by assembly personnel, which easily leads to positional deviations during surface assembly.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] In a first aspect, the present invention discloses a surface alignment and assembly system for a compass operating unit, used for aligning and assembling a surface layer on an aluminum panel of the compass operating unit, comprising a clamping assembly and a positioning drive assembly; the clamping assembly and the positioning drive assembly are slidably connected; the clamping assembly is capable of clamping the aluminum panel and keeping the aluminum panel in a horizontally extending position; the surface layer is capable of being snapped onto the lower end of the positioning drive assembly, the positioning drive assembly is capable of being aligned and assembled with the clamping assembly, and is capable of aligning and assembling the surface layer onto the aluminum panel.

[0012] As one implementation of a clamping assembly that clamps and holds an aluminum panel in a horizontally extending position, and wherein the clamping assembly is slidably connected to a positioning drive assembly, the clamping assembly includes a plurality of symmetrically and evenly arranged positioning support rods, each of which extends vertically. The outer periphery of the aluminum panel can be clamped between the plurality of positioning support rods. When the aluminum panel is correctly clamped, the aluminum panel extends horizontally. The positioning drive assembly includes a plurality of symmetrically and evenly distributed positioning sliders, each of which can be respectively fitted onto its corresponding positioning support rod, and each of the positioning sliders can be limited to being above the aluminum panel. Each of the positioning sliders can simultaneously slide vertically along its corresponding positioning support rod.

[0013] Each positioning slider can slide simultaneously on its corresponding positioning support rod, ensuring that the surface layer on the positioning drive assembly can always maintain a horizontal and lateral extension state when it falls, thereby ensuring that the surface layer can be aligned and uniformly assembled on the aluminum panel.

[0014] As one implementation of the positioning drive component being able to be aligned and assembled with the clamping component and to align and assemble the surface layer onto the aluminum panel, the positioning drive component also includes a motor. Correspondingly, each of the positioning sliders is rotatably connected to a rotating shaft, and each of the rotating shafts can be driven to rotate simultaneously by the motor.

[0015] Each of the rotating axes passes through its corresponding positioning slider, and a rotating release component is fixed to one end of each of the corresponding positioning sliders. There is a gap between the upper surface of each rotating release component and the lower surface of its corresponding positioning slider. The vertical height of the gap is adapted to the thickness of the surface layer. Each of the rotating release components can rotate simultaneously with its corresponding rotating axis.

[0016] Each of the rotating release components has a release end. When the surface layer is not released, each release end is far away from the surface layer, so that the periphery of the surface layer can be locked in each of the gaps, and the surface layer extends horizontally. When the surface layer needs to be released, each of the rotating shafts rotates simultaneously, so that each of the release ends rotates to the surface layer simultaneously, so that each of the release ends releases the surface layer onto the aluminum panel surface at the same time, realizing the alignment and assembly of the surface layer and the aluminum panel.

[0017] The working principle of this solution is as follows: This solution fully considers the characteristics of the aluminum panel and the surface layer themselves, namely, both are plate structures. Clamping components and positioning drive components are used to limit the aluminum panel and the surface layer to ensure and maintain a stable relative positional relationship between them. During assembly, the aluminum panel is first clamped in the clamping component, keeping it horizontally extended. The clamping component also provides an assembly platform for the surface layer. Then, the outer periphery of the surface layer is clamped in the various gaps, ensuring that the release end of the rotating release component is far away from the surface layer, ensuring that the surface layer is stably clamped on the positioning drive component. Then, each positioning slider of the positioning drive component is sleeved on the corresponding positioning support rod, so that the surface layer is suspended above the aluminum panel and parallel to the aluminum panel. Then, the motor is started, driving the rotating shaft to rotate, so that each release end rotates to the position of the surface layer, and at the same time, the surface layer is released, allowing the surface layer to fall vertically onto the aluminum panel in an aligned manner, realizing the alignment and assembly of the surface layer and the aluminum panel.

[0018] As one implementation of the clamping assembly, the clamping assembly includes four clamping arms and a central fixing seat. One end of each of the four clamping arms is fixedly connected to the central fixing seat, and the other end of each of the four clamping arms is detachably connected to a positioning support rod. The four clamping arms are symmetrically distributed in two groups around the central fixing seat. The two clamping arms in each group are opposite each other and have the same length and coincident center lines. The center lines of one group of clamping arms and the center lines of the other group of clamping arms are located in the same plane and are perpendicular to each other.

[0019] This solution simplifies the clamping components, setting only four clamping arms. While simplifying the structure and reducing manufacturing costs, it can still ensure the clamping effect on the aluminum panel.

[0020] As one way to limit the positioning slider to the top of the aluminum panel, each positioning support rod is detachably connected to a positioning piece, and the installation height of each positioning piece on the corresponding positioning support rod is the same. The positioning slider is provided with a through hole, and the outer circumference of the positioning piece is larger than the outer circumference of the through hole, which can prevent the positioning slider from continuing to slide vertically down.

[0021] The positioning plate can restrict the position of the positioning slider to the top of the aluminum panel. By precisely designing the position of the positioning plate, the distance of the positioning slider to the aluminum panel can be made as close as possible to the aluminum panel. This reduces the falling distance of the surface layer that is engaged with the positioning slider and decreases the possibility of positional deviation of the surface layer during the falling process.

[0022] To facilitate the clamping of aluminum panels onto the clamping assembly and broaden the applicability of the alignment assembly system, as a preferred embodiment of the clamping assembly, each clamping arm is an elastic telescopic rod. A spring-loaded sliding block is installed around the central fixed seat, and each elastic telescopic rod is slidably connected to its corresponding spring-loaded sliding block. Each elastic telescopic rod includes a sliding sleeve containing a spring. One end of the spring is fixed to one end of the elastic telescopic rod, and the other end is fixed to the central fixed seat. External force pulling the elastic telescopic rod stretches the spring, causing the elastic telescopic rod to move away from the central fixed seat. When the external force is removed, the spring contracts, causing the elastic telescopic rod to move towards the central fixed seat.

[0023] The adjustable clamping assembly can be freely adjusted according to the size and tolerance of the surface layer, and can be used for the assembly of products of different sizes, improving the assembly qualification rate and saving labor costs. This solution can be adapted to the assembly process of various similar structures. For the compass operating unit described in this application, when clamping the aluminum panel, the external force pulls each elastic telescopic rod, the elastic telescopic rod slides on the spring fixed slide, the elastic telescopic rod moves away from the central fixed seat, the aluminum panel is placed between each positioning support rod, and the external force is withdrawn, causing each spring to contract, driving the elastic telescopic rod to move towards the central fixed seat, so that each positioning support rod clamps the aluminum panel around its perimeter.

[0024] As one implementation of the positioning drive component, the positioning drive component includes a drive gear, which is fixedly connected to the output end of the motor. When the motor rotates, it can drive the drive gear to rotate synchronously.

[0025] Correspondingly, each of the rotating shafts has a driven gear fixed at the end away from the positioning slider. The driven gear can mesh with the driving gear, and when the driving gear rotates, it can drive the driven gear to rotate synchronously.

[0026] In this way, it is possible to achieve the technical effect that each of the rotating shafts can be driven to rotate simultaneously by the motor. When the surface layer is released, each of the rotating shafts rotates simultaneously under the drive of the driven gear, so that each of the release ends rotates to the surface layer at the same time, and each of the release ends releases the surface layer onto the surface of the aluminum panel at the same time, so as to achieve the alignment and assembly of the surface layer and the aluminum panel.

[0027] As a preferred embodiment of the alignment assembly system, the alignment assembly system also includes an automatic pressure application mechanism, which is used to apply pressure to the surface layer after aligning and assembling the surface layer with the aluminum panel, to further solve the technical problem of weak adhesion between the surface layer and the aluminum panel, and to further improve assembly efficiency and assembly effect.

[0028] The automatic pressure application mechanism includes a pressure application fixing bracket and a pressure application fixing base. The pressure application fixing base is located below the clamping assembly. The pressure application fixing bracket is inserted into the pressure application fixing base, and the pressure application fixing base is detachable. A pressure application assembly is rotatably connected to the pressure application fixing bracket. The pressure application assembly includes a pressure application plate. A force transmission part is fixed on the top of the pressure application plate. The force transmission part has two centrally symmetrical slots. A thrust transmission handle is respectively engaged in each slot. The thrust transmission handle is fixed on a drive gear. The drive gear drives the thrust transmission handle to rotate, thereby driving the pressure plate to rotate to a specific position, at which point the pressure plate can fall vertically from the pressure application fixing bracket.

[0029] The technical principle of this solution is as follows: When the drive gear rotates, the two centrally symmetrical thrust transmission handles fall into the corresponding slots and drive the pressure plate to rotate through the force transmission part. After the rotating release part at the bottom of the positioning slider releases the surface layer, the drive gear continues to rotate by a small angle. At this time, the thrust transmission handle continues to push the force transmission part to make the pressure plate rotate. At this time, the thrust transmission handle has left the slot, and then the pressure plate falls onto the surface layer, thereby achieving uniform adhesion of the surface layer.

[0030] Secondly, the present invention also discloses a surface alignment assembly method for a compass operating unit, employing the alignment assembly system described above, comprising the following steps:

[0031] S1. Assemble the clamping assembly and place it on the worktable, ensuring its stability;

[0032] S2. Place the aluminum panel between the positioning support rods of the clamping assembly for clamping, ensuring that the aluminum panel extends horizontally.

[0033] S3. Assemble the positioning drive assembly and secure the periphery of the surface layer in the gap between each positioning slider and the corresponding rotary release component.

[0034] S4. Place each positioning slider onto its corresponding positioning support rod, and limit the height of each positioning slider by the positioning piece on the corresponding positioning support rod.

[0035] S5. Start the motor, drive the drive gear to rotate, and then drive each rotating shaft to rotate through the driven gear. This causes the release ends of each rotating release component on each positioning slider to rotate to the surface layer, releasing the surface layer so that it falls vertically onto the aluminum panel, thus aligning and assembling the surface layer on the aluminum panel. Then, remove the aluminum panel with the correctly assembled surface layer to complete the assembly process.

[0036] The present invention discloses a surface layer alignment and assembly method for a compass operating unit. Utilizing an alignment and assembly system, the surface layer and aluminum panel are separately snapped together, ensuring their horizontal extension and alignment. Through simple rotation of related components, the vertical alignment and assembly of the surface layer can be achieved. The assembly process is simple and convenient, reducing the skill requirements for operators, improving assembly efficiency and success rate. It solves the technical problem that the surface layer of the compass operating unit often requires manual assembly, which can easily lead to positional deviations during assembly, and has promising application prospects.

[0037] Preferably, in step S3, after the periphery of the surface layer is secured in the gap between each positioning slider and the corresponding rotating release component, the automatic pressure mechanism also needs to be assembled. The automatic pressure mechanism includes a pressure fixing bracket and a pressure fixing base. The pressure fixing bracket is inserted into the pressure fixing base. First, the pressure fixing base of the automatic pressure mechanism is placed below the clamping assembly, and then the pressure fixing bracket is inserted into the pressure fixing base.

[0038] A pressure-applying component is rotatably connected to the pressure-applying fixing bracket. The pressure-applying component includes a pressure-applying plate. A force-transmitting part is fixed on the top of the pressure-applying plate. Two centrally symmetrical slots are opened on the force-transmitting part. A thrust transmission handle is respectively engaged in each slot. The thrust transmission handle is fixed on the drive gear.

[0039] Then continue with step S4, where each positioning slider is fitted onto its corresponding positioning support rod, and the height of each positioning slider is limited by the positioning piece on the corresponding positioning support rod.

[0040] Then, continuing with step S5, the motor is started, which drives the drive gear to rotate, which in turn drives each rotating shaft to rotate through the driven gear. This causes the release ends of each rotating release component on each positioning slider to rotate to the surface layer, releasing the surface layer so that it falls vertically onto the aluminum panel. The drive gear continues to rotate, which drives the thrust transmission handle to rotate, which in turn drives the pressure plate to rotate to a specific position. The pressure plate falls vertically from the pressure fixing bracket and applies uniform pressure to the front and back layers to ensure that the surface layer is firmly attached to the aluminum panel.

[0041] The present invention has the following beneficial effects: The alignment assembly system disclosed in this invention can solve the technical problem that the surface layer of the compass operating unit often needs to be manually assembled by the assembler, which easily leads to positional deviations during the surface layer assembly, such as edge skewing, button openings, display screen openings, indicator light openings, etc.; The alignment assembly system uses a motor to provide driving force, driving each rotating release component to rotate and release the surface layer at the same time, which can realize the alignment assembly of the surface layer by aligning the surface layer with the aluminum panel at the same time.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0063] It should be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship commonly used when the product is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In addition, the terms "horizontal," "vertical," etc., do not indicate that the component is required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted. In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0064] This invention can be applied to the assembly process of the surface layer of a compass operating unit, solving the technical problem that the surface layer of a compass operating unit often requires manual assembly by assembly personnel, which easily leads to positional deviations during assembly. The purpose of this invention is to improve the pass rate of surface layer assembly during the manufacturing process and reduce assembly time and costs by adopting a new surface layer assembly system. The surface layer assembly system of this invention adopts a manual-automatic combination mode, is small in size and light in weight, and is easy to assemble correctly. Furthermore, the assembly system can be adapted to products of various sizes other than compass operating units, making it widely applicable.

[0065] Firstly, please refer to Figures 3 to 5Based on the aforementioned technical problems, this invention discloses a surface alignment and assembly system and method for a compass operating unit, used for aligning and assembling a surface layer 102 on an aluminum panel 101 of a compass operating unit 100. The system includes a clamping assembly 200 and a positioning drive assembly 300. The clamping assembly 200 and the positioning drive assembly 300 are slidably connected. The clamping assembly 200 can clamp the aluminum panel 101 and maintain it in a horizontally extending position. The surface layer 102 can be snapped onto the lower end of the positioning drive assembly 300. The positioning drive assembly 300 can be aligned and assembled with the clamping assembly 200, and can align and assemble the surface layer 102 onto the aluminum panel 101.

[0066] The clamping assembly 200 includes a plurality of symmetrically and evenly arranged positioning support rods 201, each of the positioning support rods 201 extending vertically, the outer periphery of the aluminum panel 101 being clamped between the plurality of positioning support rods 201, and when the aluminum panel 101 is correctly clamped, the aluminum panel 101 extends horizontally.

[0067] The positioning drive component 300 includes a plurality of symmetrically and evenly distributed positioning sliders 209. Each positioning slider 209 can be respectively sleeved on its corresponding positioning support rod 201, and each positioning slider 209 can be limited to the top of the aluminum panel 101. Each positioning slider 209 can slide vertically along its corresponding positioning support rod 201 at the same time.

[0068] The positioning drive assembly 300 also includes a motor 301. Correspondingly, each positioning slider 209 is rotatably connected to a rotating shaft 207, and each rotating shaft 207 can be driven to rotate simultaneously by the motor 301.

[0069] Please see Figure 5 Each of the rotating shafts 207 passes through its corresponding positioning slider 209, and a rotating release member 208 is fixed to one end of each of the corresponding positioning sliders 209. There is a gap between the upper surface of each rotating release member 208 and the lower surface of its corresponding positioning slider 209. The vertical height of the gap is adapted to the thickness of the surface layer 102. Each rotating release member 208 can rotate simultaneously with its corresponding rotating shaft 207.

[0070] Each of the rotating release components 208 has a release end. When the surface layer 102 is not released, each release end is far away from the surface layer 102, so that the periphery of the surface layer 102 can be locked in each of the gaps, and the surface layer 102 extends horizontally. When the surface layer 102 needs to be released, each of the rotating shafts 207 rotates simultaneously, so that each release end rotates simultaneously to the surface layer 102, so that each release end releases the surface layer 102 onto the surface of the aluminum panel 101, thereby achieving the alignment and assembly of the surface layer 102 and the aluminum panel 101.

[0071] The working principle of this solution is as follows: This solution fully considers the characteristics of the aluminum panel 101 and the surface layer 102, both of which are plate structures. Clamping components 200 and positioning drive components 300 are used to limit the aluminum panel 101 and the surface layer 102, ensuring and maintaining a stable relative positional relationship between them. During assembly, the aluminum panel 101 is first clamped in the clamping component 200, maintaining its horizontal extension. The clamping component 200 also serves as an assembly platform for the surface layer 102. Then, the outer periphery of the surface layer 102 is engaged in the various gaps, ensuring the rotation release mechanism... The release end of 208 is far away from the surface layer 102, ensuring that the surface layer 102 is stably locked on the positioning drive component 300. Then, each positioning slider 209 of the positioning drive component 300 is sleeved on the corresponding positioning support rod 201, so that the surface layer 102 is suspended above the aluminum panel 101 and parallel to the aluminum panel 101. Then, the motor 301 is started, driving the rotating shaft 207 to rotate, so that each release end rotates to the position of the surface layer 102 and releases the surface layer 102, so that the surface layer 102 falls vertically onto the aluminum panel 101 in an aligned manner, realizing the alignment and assembly of the surface layer 102 and the aluminum panel 101.

[0072] This solution solves the technical problem that when the surface layer 102 is manually assembled, the surface layer 102 is prone to positional deviation, which causes various openings on the surface layer 102 to be misaligned with the buttons 105 and the display screen 103.

[0073] Specifically, the surface layer 102 is a surface layer 102 or an outer film, and the outer film is a rigid film.

[0074] Specifically, the surface layer 102 is an acrylic sheet, and one side of the acrylic sheet has an adhesive.

[0075] Specifically, the surface layer 102 has an adhesive on the side facing the aluminum panel 101 for bonding the surface layer 102 to the aluminum panel 101.

[0076] For preference, please refer to Figure 5The support width of the rotating release member 208 on the surface layer 102 is approximately 1 to 1.5 mm. This small support width is because the side of the surface layer 102 facing the aluminum panel 101 has adhesive. Only a small contact width between the rotating release member 208 and the surface layer 102 is needed to lift the surface layer 102. At the same time, maintaining a small support width makes it easy for the rotating release member 208 to rotate away from the side of the surface layer 102 with adhesive.

[0077] For one implementation of the clamping component 200, please refer to [link / reference]. Figure 4 The clamping assembly 200 includes four clamping arms 202 and a central fixing base 204. One end of each of the four clamping arms 202 is fixedly connected to the central fixing base 204, and the other end of each of the four clamping arms 202 is detachably connected to a positioning support rod 201. The four clamping arms 202 are symmetrically distributed in two groups around the central fixing base 204. Two clamping arms 202 in each group are opposite each other and have the same length and coincident center lines. The center lines of one group of clamping arms 202 and the center lines of the other group of clamping arms 202 are located in the same plane and are perpendicular to each other.

[0078] This solution simplifies the clamping assembly 200, setting only four clamping arms 202. While simplifying the structure and reducing manufacturing costs, it can still ensure the clamping effect on the aluminum panel 101.

[0079] For details, please refer to Figure 6 Each of the clamping arms 202 is provided with a mounting position 2023 at the position for connecting with the corresponding positioning support rod 201. Each of the positioning support rods 201 is inserted into the corresponding mounting position 2023 and fixed in the mounting position 2023 by countersunk screws.

[0080] As one implementation of the positioning slider 209 being able to be positioned above the aluminum panel 101, please refer to [link to relevant documentation]. Figure 7 Each positioning support rod 201 is detachably connected to a positioning piece 2011. The installation height of each positioning piece 2011 on the corresponding positioning support rod 201 is the same. The positioning slider 209 has a through hole. The outer circumference of the positioning piece 2011 is larger than the outer circumference of the through hole, which can prevent the positioning slider 209 from continuing to slide vertically.

[0081] The positioning piece 2011 can restrict the position of the positioning slider 209 to above the aluminum panel 101. By precisely designing the position of the positioning piece 2011, the distance of the positioning slider 209 can be as close as possible to the aluminum panel 101. This reduces the falling distance of the surface layer 102 that is engaged with the positioning slider 209, thereby reducing the possibility of positional deviation of the surface layer 102 during the falling process.

[0082] For a preferred option, please refer to Figure 6 and Figure 7 The positioning support rod 201 between the side of the positioning piece 2011 facing the clamping arm 202 and the upper surface of each clamping arm 202 has a recessed locking position 2014. The outer periphery of the aluminum panel 101 can be locked in the locking position 2014 for vertically limiting the aluminum panel 101.

[0083] Limiting the vertical position of the aluminum panel 101 can prevent the aluminum panel 101 from shifting or tilting during the assembly process, thereby improving assembly efficiency, assembly success rate and the qualification rate of assembled products.

[0084] For a preferred embodiment of the stop position 2014, please refer to [link / reference]. Figure 4 A panel pad 2012 is also provided at the locking position 2014 to further restrict the vertical displacement of the aluminum panel 101. The panel pad 2012 has a horizontal bar 3022, from which a buckle extends outward. The buckle can engage with the positioning support rod 201 at the locking position 2014 from the outside in. The panel pad 2012 is used to raise the aluminum panel 101, so that the aluminum panel 101 is locked upward into the locking position 2014, thereby fixing and locking the aluminum panel 101, facilitating subsequent assembly processes. This can further improve assembly efficiency, assembly success rate, and the qualification rate of assembled products.

[0085] To facilitate the clamping of the aluminum panel 101 onto the clamping assembly 200 and to broaden the applicability of the mounting system, for the preferred embodiment of the clamping assembly 200, please refer to [reference needed]. Figure 4 Each clamping arm 202 is an elastic telescopic rod. A spring-loaded sliding block 205 is installed around the central fixed seat 204, and each elastic telescopic rod is slidably connected to its corresponding spring-loaded sliding block 205. Each elastic telescopic rod includes a sliding sleeve 2021, and a spring 203 is installed inside the sliding sleeve 2021. One end of the spring 203 is fixed to one end of the elastic telescopic rod, and the other end of the spring 203 is fixed to the central fixed seat 204. When an external force pulls the elastic telescopic rod, it can stretch the spring 203, causing the elastic telescopic rod to move away from the central fixed seat 204. After the external force is removed, the spring 203 contracts, which can drive the elastic telescopic rod to move towards the central fixed seat 204.

[0086] The adjustable clamping assembly 200 can be freely adjusted according to the size and tolerance of the surface layer 102, and can be used for the assembly of products of different sizes, improving the assembly qualification rate and saving labor costs. This solution can adapt to the assembly process of various similar structures. For the compass operating unit 100 described in this application, when clamping the aluminum panel 101, the external force pulls each elastic telescopic rod, the elastic telescopic rod slides on the spring fixed slide 205, the elastic telescopic rod moves away from the central fixed seat 204, the aluminum panel 101 is placed between each positioning support rod 201, and the external force is withdrawn, causing each spring 203 to contract, driving the elastic telescopic rod to move towards the central fixed seat 204, so that each positioning support rod 201 clamps the aluminum panel 101 around its perimeter.

[0087] As one way to fix the spring 203, the two ends of the spring 203 are fixed by a first spring positioning pin 2031 and a second spring positioning pin 2032, respectively. The first spring positioning pin 2031 is located at the end of the elastic telescopic rod away from the central fixed seat 204 and is fixedly connected to the opposite side walls of the elastic telescopic rod; the second spring positioning pin 2032 is fixed on the spring fixing slide 205.

[0088] Specifically, the two ends of the spring 203 have hooks, which are hooked onto the first spring positioning pin 2031 and the second spring positioning pin 2032, respectively.

[0089] For one implementation of the spring-loaded fixed slide 205, please refer to [link / reference]. Figure 7 The spring fixing slide 205 includes a fixed end 2051 and a horizontally extending sliding shaft 2052. The fixed end 2051 is installed on the central fixing seat 204. The sliding shaft 2052 includes two symmetrically arranged semi-cylinders with an installation gap between them. Each of the two semi-cylinders has a through hole for inserting a second spring positioning pin 2032. One end of the spring 203 is fixed on the second spring positioning pin 2032.

[0090] For the corresponding information, please refer to [link / reference]. Figure 6 The sliding sleeve 2021 has a circular hole 2022 at one end facing the central fixed seat 204, and the sliding shaft 2052 extends into the circular hole 2022 to realize the sliding connection between the sliding sleeve 2021 and the spring fixed slide 205;

[0091] The length of the sliding shaft 2052 is adapted to the maximum tensile length of the spring 203 to ensure that the elastic telescopic rod will not detach from the sliding shaft 2052.

[0092] For one implementation of the positioning driver component 300, please refer to [link / reference]. Figure 4The positioning drive assembly 300 includes a drive gear 303, which is fixedly connected to the output end of the motor 301. When the motor 301 rotates, it can drive the drive gear 303 to rotate synchronously.

[0093] Correspondingly, a driven gear 206 is fixed at one end of each of the rotating shafts 207 away from the positioning slider 209. The driven gear 206 can mesh with the driving gear 303. When the driving gear 303 rotates, it can drive the driven gear 206 to rotate synchronously.

[0094] In this way, it is possible to achieve the technical effect that each of the rotating shafts 207 can be driven to rotate simultaneously by the motor 301. When the surface layer 102 is released, each of the rotating shafts 207 rotates simultaneously under the drive of the driven gear 206, so that each of the release ends rotates to the surface layer 102 at the same time, and each of the release ends releases the surface layer 102 onto the surface of the aluminum panel 101 at the same time, so as to achieve the alignment and assembly of the surface layer 102 and the aluminum panel 101.

[0095] Specifically, the driven gear 206 can be clamped and released from the surface layer 102 by rotating clockwise or counterclockwise by less than 50°.

[0096] As one embodiment of the rotation angle of the driven gear 206, the motor 301 drives the drive gear 303 to rotate and drives the driven gear 206 to rotate clockwise by 45°, which can achieve clamping of the surface layer 102. Subsequently, after the positioning slider 209 moves down to the preset position, the motor 301 drives the drive gear 303 to rotate and drives the driven gear 206 to rotate counterclockwise by 45°, which can achieve releasing the surface layer 102.

[0097] Specifically, in practice, the rotation angle of motor 301 is controlled by the control board, so that motor 301 can rotate forward or backward, thereby driving the driven gear 206 to rotate clockwise or counterclockwise.

[0098] For details, please refer to Figure 4 The motor 301 is mounted on a motor 301 mounting bracket. The motor 301 mounting bracket has crossbars 3022 corresponding to each positioning slider 209. Each crossbar 3022 extends horizontally, and a positioning shaft 3021 is fixed at the extended end of each crossbar 3022. Each positioning shaft 3021 is fixedly connected to the corresponding positioning slider 209. During assembly, the surface layer 102 is first inserted into the gap at the bottom of the fixed slider, and then each fixed slider in the positioning drive assembly 300 is sleeved on the positioning support rod 201 to achieve the alignment and assembly of the clamping assembly 200 and the positioning drive assembly 300.

[0099] For details, please refer to Figure 4The positioning slider 209 is provided with a blind hole 2091, and the positioning shaft 3021 is fixed in the blind hole 2091.

[0100] Specifically, the positioning shaft 3021 is used to support the positioning drive assembly 300 to slide downward along the positioning support rod 201 with the positioning slider 209.

[0101] Specifically, the rotating release component 208 is a ring structure, the release end is a cross-section 2082, and the length of any line connecting the center of the ring structure to the cross-section 2082 is less than the radius of the outer ring of the ring structure.

[0102] For details, please refer to Figure 8 The rotating release component 208 adopts a positioning pad 2081, which is an annular pad with a tangent 2082 on its outer periphery. The length of any line connecting the center of the annular pad to the tangent 2082 is less than the radius of the outer ring of the annular structure.

[0103] Specifically, the positioning pad 2081 is made of aluminum.

[0104] To better accommodate cases where both aluminum panel 101 and surface layer 102 are rectangular, as one implementation method for various structures in the alignment assembly system, please refer to [link / reference needed]. Figures 9 to 13 The spring 203 telescopic rod includes two opposing short shaft sliding sleeves 210 and two opposing long shaft sliding sleeves 212. The center lines of the two short shaft sliding sleeves 210 are located on a first straight line, and the center lines of the two long shaft sliding sleeves 212 are located on a second straight line. The first straight line and the second straight line are located on the same plane and are perpendicular to each other.

[0105] Each of the two short shaft sleeves 210 has a short shaft spring 211 fixed inside. One end of each short shaft spring 211 is fixed to one end of the corresponding short shaft sleeve 210, and the other end of each short shaft spring 211 is fixed to the corresponding spring fixing slide 205.

[0106] Each of the two long-axis sliding sleeves 212 has a long-axis spring 213 fixed inside. One end of each long-axis spring 213 is fixed to one end of the corresponding long-axis sliding sleeve 212, and the other end of each long-axis spring 213 is fixed to the corresponding spring fixing slide 205.

[0107] Two short shaft sliding sleeves 210 and two long shaft sliding sleeves 212 are respectively fixed with positioning support rods 201 at one end away from the central fixed seat 204. Each positioning support rod 201 is slidably connected with a positioning slider 209. Each positioning slider 209 is rotatably connected with a rotating shaft 207. Each rotating shaft 207 is fixed with a driven gear 206 at its top end.

[0108] Please see Figure 13 The drive gear 303 has a drive disk 3031 at its center. On both sides of the drive disk 3031, symmetrical sector gear disks 3032 extend outward from the edge of the drive disk 3031. The edges of the sector gear disks 3032 have long shaft drive teeth 3034, and each of the long shaft drive teeth 3034 can mesh with the driven gear 206 corresponding to the side of the long shaft sleeve 212. In addition to the opposite edges of the sector gear disks 3032 extending from the drive disk 3031, the opposite edges of the drive disk 3031 have short shaft drive teeth 3035, which can mesh with the driven gear 206 corresponding to the side of the short shaft sleeve 210.

[0109] For the corresponding information, please refer to [link / reference]. Figure 12 The crossbar 3022 of the motor 301 fixing frame has two long axis crossbars 304 and two short axis crossbars 305, which can be fixedly connected to the positioning sliders 209 on the corresponding sides respectively.

[0110] By adopting the structure of the drive gear 303 described above, it is possible to achieve multi-directional transmission driven by a single motor 301. The entire mechanism is small in size and light in weight, which greatly saves operating space and processing costs.

[0111] During assembly, the aluminum panel 101 is first clamped in the clamping assembly 200 according to its matching with the long axis sliding sleeve 212 and the short axis sliding sleeve 210, maintaining its horizontal extension. The clamping assembly 200 also serves as an assembly platform for the assembly surface layer 102. Then, the surface layer 102 is positioned in the gaps according to the direction corresponding to the length and width of the aluminum panel 101, ensuring that the release end of the rotary release member 208 is far away from the surface layer 102, thus ensuring that the surface layer 102 is stably clamped onto the positioning drive assembly 300. Finally, each positioning slider 209 of the positioning drive assembly 300 is fitted onto its corresponding position. Positioning support rod 201, so that surface layer 102 is suspended above aluminum panel 101 and parallel to aluminum panel 101. Then, motor 301 is started, driving drive gear 303 to rotate. Through the long shaft drive gear 3034 and short shaft drive gear 3035 respectively meshing with driven gear 206, each driven gear 206 is driven to rotate simultaneously, which in turn drives each rotating shaft 207 to rotate, so that each release end rotates to the position of surface layer 102 and releases surface layer 102, so that surface layer 102 falls vertically onto aluminum panel 101 in an aligned manner, realizing the alignment and assembly of surface layer 102 and aluminum panel 101.

[0112] Specifically, for the above solution, since the transmission ratios of the long shaft drive gear 3034 and the short shaft drive gear 3035 are different, if it is necessary to achieve simultaneous release of the surface layer 102 by each rotary release component 208, the release end of the rotary release component 208 needs to be pre-rotated and adjusted. The pre-rotation angle range is 30°~45°, so that within the rotation angle range of each rotary shaft 207 (i.e., within the rotation angle range of the driven gear 206), each release end can rotate to the surface layer 102 simultaneously, thereby achieving simultaneous release of the surface layer 102.

[0113] Secondly, regarding the alignment assembly system described above, the present invention also discloses a surface alignment assembly method for a compass operating unit, comprising the following steps:

[0114] S1. Assemble the clamping assembly 200 and place it on the worktable to ensure its stability;

[0115] S2. Place the aluminum panel 101 between the positioning support rods 201 of the clamping assembly 200 for clamping, ensuring that the aluminum panel 101 extends horizontally.

[0116] S3. Assemble the positioning drive assembly 300 and lock the periphery of the surface layer 102 in the gap between each positioning slider 209 and the corresponding rotation release component 208.

[0117] S4. Each positioning slider 209 is fitted onto the corresponding positioning support rod 201, and the height of each positioning slider 209 is limited by the positioning piece 2011 on the corresponding positioning support rod 201.

[0118] S5. Start the motor 301, drive the drive gear 303 to rotate, and then drive each rotating shaft 207 to rotate through the driven gear 206. This causes the release ends of each rotating release component 208 on each positioning slider 209 to rotate to the surface layer 102, and at the same time release the surface layer 102 so that it falls vertically onto the aluminum panel 101, thus aligning and assembling the surface layer 102 on the aluminum panel 101. Then, remove the aluminum panel 101 with the surface layer 102 correctly assembled, completing the assembly process.

[0119] Specifically, in step S1, after placing the alignment assembly system on the workbench, all components need to be inspected, including clamping components, positioning drive components, motors, automatic pressure mechanisms, etc., to ensure that they are intact and correctly installed.

[0120] Specifically, in step S5, after removing the correctly assembled aluminum panel with the surface layer, it is also necessary to check the assembly quality of the surface layer. If there is any deviation, fine-tuning should be performed.

[0121] Specifically, in step S5, after the assembly is completed, the assembly system needs to be cleaned in a timely manner to remove residues, and the system needs to be maintained in preparation for the next use.

[0122] For the preferred option of the positive assembly system, please refer to Figures 14 to 18 The alignment assembly system also includes an automatic pressure application mechanism 400, which applies pressure to the surface layer 102 after the surface layer 102 and the aluminum panel 101 are aligned and assembled, further solving the technical problem of weak adhesion between the surface layer 102 and the aluminum panel 101, and further improving assembly efficiency and assembly effect.

[0123] The automatic pressure application mechanism 400 includes a pressure application fixing bracket 401 and a pressure application fixing base 403. The pressure application fixing base 403 is disposed below the clamping assembly 200. The pressure application fixing bracket 401 is inserted into the pressure application fixing base 403, and the pressure application fixing base 403 is detachable. A pressure application assembly 402 is rotatably connected to the pressure application fixing bracket 401. The pressure application assembly 402 includes a pressure application plate 4021. A force transmission part 4022 is fixed on the top of the pressure application plate 4021. The force transmission part 4022 has two centrally symmetrical slots 4023. A thrust transmission handle 404 is respectively engaged in each slot 4023. The thrust transmission handle 404 is fixed on the drive gear 303. The drive gear 303 drives the thrust transmission handle 404 to rotate, thereby driving the pressure application plate 4021 to rotate to a specific position, at which point the pressure application plate 4021 can fall vertically from the pressure application fixing bracket 401.

[0124] The technical principle of this solution is as follows: When the drive gear 303 rotates, the two centrally symmetrical thrust transmission handles 404 fall into the corresponding slots 4023 and drive the pressure plate 4021 to rotate through the force transmission part 4022. After the rotation release part 208 at the bottom of the positioning slider 209 releases the surface layer 102, the drive gear 303 continues to rotate by a small angle. At this time, the thrust transmission handles 404 continue to push the force transmission part 4022 to make the pressure plate 4021 rotate. At this time, the thrust transmission handles 404 have left the slots 4023, and then the pressure plate 4021 falls onto the surface of the surface layer 102, thereby achieving uniform adhesion of the surface layer 102.

[0125] For details, please refer to Figure 16The edge of the pressure fixing bracket 401 extends vertically downward with multiple plug-in plates 4011. Correspondingly, the edge of the pressure fixing base 403 is provided with multiple slots 4031. The plug-in plates 4011 are inserted into the slots 4031 to achieve plug-in connection. This facilitates fixing the bracket and prevents the pressure fixing bracket 401 from rotating. This also facilitates the replacement of the surface layer 102 and makes it easy to lift and remove the entire pressure plate 4021 and pressure fixing bracket, avoiding the time-consuming disassembly of screw connections, thereby greatly improving work efficiency.

[0126] For details, please refer to Figure 16 The bottom of the pressure plate 4021 is attached with a pressure damping pad 405, which is a silicone damping pad, to prevent damage to the surface layer 102 when the pressure plate 4021 falls.

[0127] For one implementation of the thrust transmission handle 404, please refer to [link / reference]. Figure 17 The thrust transmission handle 404 includes a force receiving end 4041 and a force transmitting end 4044. The sector gear disk 3032 has a circular hole 3033, and the force receiving end 4041 has a mounting threaded hole 4043. The mounting threaded hole 4043 is connected to the circular hole 3033 of the sector gear disk 3032 by screws. The force transmitting end 4044 is engaged in the slot 4023.

[0128] The edge of the force-receiving end 4041 has a vertically upward extending positioning boss 4042. The positioning boss 4042 extends vertically upward from the edge of the force-receiving end 4041 and abuts against the edge of the sector gear disk 3032. When the sector gear disk 3032 rotates, it can apply a thrust to the positioning boss 4042, thereby enabling the force transmission end 4044 to push the force transmission part 4022 to rotate.

[0129] Installing two thrust transmission handles 404 allows the drive gear 303 to rotate simultaneously from two directions, pushing the force transmission part 4022 of the pressure plate 4021 to rotate. After the force transmission end 4044 is unscrewed from the slot 4023, the pressure plate 4021 falls down, and the positioning boss 4042 is used to hold the edge of the sector gear, thus preventing the handle from rotating.

[0130] The working process of this solution is as follows: First, assemble the pressure-applying fixing base 403 and the clamping assembly 200. Then, install the aluminum panel 101 into the clamping assembly 200, and then use panel pads 2012 to position and fix the aluminum panel 101 in four directions. Next, install the four positioning sliders 209 into the four positioning support rods 201. After peeling off the adhesive paper of the surface layer 102, gently place it on the four release devices. Next, install the pressure plate 4021 and the pressure-applying fixing bracket 401 into the pressure-applying fixing base 403. Next, install the thrust transmission handle 404 into the circular hole 3033 of the sector gear disk 3032 of the positioning drive assembly 300. Next, connect the driven gear 206 to the positioning slider 209 so that the drive gear 303 and the driven gear 206 can cooperate correctly, and the rotation is controlled by the circuit board. After releasing the surface layer 102, push the pressure plate 4021 to fall and apply pressure. Finally, remove the panel clips 2012 from all four directions, remove the fixing bracket and pressure plate 4021 from the clamping assembly 200 and the automatic pressure mechanism 400, and finally remove the assembled product. Repeat the above steps to assemble the next product.

[0131] Specifically, the thrust transmission handle 404 is made of aluminum, which is lightweight.

[0132] Specifically, the pressure-absorbing pads are directly attached to the bottom of the pressure plate 4021 using 3M adhesive, and the position and quantity are determined according to the shape of the surface layer 102.

[0133] Specifically, the pressure fixing base 403 has a square hole 4032 at its center, and correspondingly, the bottom of the central fixing base 204 has a square protrusion 2041 whose outer circumference is adapted to the inner circumference of the square hole 4032. The square protrusion 2041 extends out of the square hole 4032, thereby playing the role of fixing and preventing rotation.

[0134] Specifically, the spring fixing slide 205 is connected and fixed to the center fixing seat 204 from the bottom by countersunk screws.

[0135] Therefore, in response to the preferred scheme of the above-mentioned alignment system, the surface alignment method used for the compass operating unit will also be improved accordingly, including the following steps:

[0136] A1. Assemble the clamping assembly 200 and place it on the worktable to ensure its stability;

[0137] A2. Place the aluminum panel 101 between the positioning support rods 201 of the clamping assembly 200 for clamping, ensuring that the aluminum panel 101 extends horizontally.

[0138] A3. Assemble the positioning drive assembly 300, and lock the periphery of the surface layer 102 in the gap between each positioning slider 209 and the corresponding rotation release component 208.

[0139] A4. Assemble the automatic pressure application mechanism 400, which includes a pressure fixing bracket 401 and a pressure fixing base 403. The pressure fixing bracket 401 is inserted into the pressure fixing base 403. First, place the pressure fixing base 403 of the automatic pressure application mechanism 400 below the clamping assembly 200, and then insert the pressure fixing bracket 401 into the pressure fixing base 403.

[0140] A pressure-applying component 402 is rotatably connected to the pressure-applying fixing bracket 401. The pressure-applying component 402 includes a pressure-applying plate 4021. A force-transmitting part 4022 is fixed on the top of the pressure-applying plate 4021. Two centrally symmetrical slots 4023 are opened on the force-transmitting part 4022. A thrust transmission handle 404 is respectively engaged in each of the slots 4023. The thrust transmission handle 404 is fixed on the drive gear 303.

[0141] A5. Place each positioning slider 209 onto the corresponding positioning support rod 201, and limit the height of each positioning slider 209 by the positioning piece 2011 on the corresponding positioning support rod 201.

[0142] A6. Start the motor 301, which drives the drive gear 303 to rotate, which in turn drives the driven gear 206 to rotate each rotating shaft 207. This causes the release ends of the rotating release parts 208 on each positioning slider 209 to rotate to the surface layer 102, releasing the surface layer 102 so that it falls vertically onto the aluminum panel 101. Continue to drive the drive gear 303 to rotate, which drives the thrust transmission handle 404 to rotate, which in turn drives the pressure plate 4021 to rotate to a specific position. The pressure plate 4021 falls vertically from the pressure fixing bracket 401 and applies uniform pressure to the surface layer 102 to ensure that the surface layer 102 is firmly assembled with the aluminum panel 101. Then, remove the aluminum panel 101 with the surface layer 102 correctly assembled, completing the assembly process.

[0143] The surface alignment assembly system and alignment assembly method for compass operating units disclosed in this invention have the following technical advantages:

[0144] 1. The alignment assembly system can solve the technical problem that the surface layer of the compass operating unit often needs to be manually assembled by the assembler, which can easily lead to positional deviations during the assembly of the surface layer, such as edge skewing, button openings, display screen openings, indicator light openings, etc.

[0145] 2. The alignment assembly system uses a motor to provide driving force, and employs the force transmission and linkage of drive gears, driven gears, and rotary release components to enable one motor to drive multiple structures simultaneously to achieve force transmission. This allows the surface layer to be released while aligning with the aluminum panel, thus achieving the alignment assembly of the surface layer.

[0146] 3. The alignment assembly system has a small overall size, which greatly saves operating space and significantly reduces the processing cost of the mechanism. In addition, the whole machine uses aluminum support, which is lightweight and can be operated independently by one person, reducing the difficulty of operation. During assembly, a combination of manual and automatic assembly methods can be used, or fully automatic assembly can be achieved, which improves assembly efficiency and success rate and saves labor costs.

[0147] 4. It adopts a retractable clamping component, which can realize the assembly of products of various sizes. It can be applied to multiple operating surface areas and other film products, not limited to fiber optic compasses, and has a wide range of applications.

[0148] 5. The surface layer alignment assembly method for a compass operating unit disclosed in this invention utilizes an alignment assembly system to achieve separate snap-fitting of the surface layer and the aluminum panel, ensuring their respective horizontal extension and alignment. Through simple rotation operations of related components, the vertical alignment and assembly of the surface layer can be achieved. The assembly process is simple and convenient, reducing the skill requirements for operators, improving assembly efficiency and success rate, and solving the technical problem that the surface layer of the compass operating unit often requires manual assembly by assemblers, which easily leads to positional deviations during surface layer assembly. It also has good application prospects.

Each of the rotating axes passes through its corresponding positioning slider, and a rotating release component is fixed to one end of each of the corresponding positioning sliders. There is a gap between the upper surface of each rotating release component and the lower surface of its corresponding positioning slider. The vertical height of the gap is adapted to the thickness of the surface layer. Each of the rotating release components can rotate simultaneously with its corresponding rotating axis. Each of the rotating release components has a release end. When the surface layer is not released, each release end is far away from the surface layer, so that the periphery of the surface layer can be locked in each of the gaps, and the surface layer extends horizontally. When the surface layer needs to be released, each of the rotating shafts rotates simultaneously, so that each of the release ends rotates to the surface layer simultaneously, so that each of the release ends releases the surface layer onto the aluminum panel surface at the same time, realizing the alignment and assembly of the surface layer and the aluminum panel.

One end of each of the four clamping arms is fixedly connected to the central fixing base, and the other end of each of the four clamping arms is detachably connected to a positioning support rod. The four clamping arms are symmetrically distributed in two groups around the central fixing base. The two clamping arms in each group are opposite each other and have the same length, with their center lines coinciding. The center lines of one group of clamping arms and the center lines of the other group of clamping arms are located on the same plane and are perpendicular to each other.

3. The surface alignment assembly system for a compass operating unit according to claim 2, characterized in that, Each positioning support rod is detachably connected to a positioning piece, and the installation height of each positioning piece on the corresponding positioning support rod is the same. The positioning slider has a through hole, and the outer circumference of the positioning piece is larger than the outer circumference of the through hole, which can prevent the positioning slider from continuing to slide vertically downward.

4. The surface alignment assembly system for a compass operating unit according to claim 3, characterized in that, Each of the clamping arms is an elastic telescopic rod, and a spring fixing slide is installed around the central fixing seat. Each elastic telescopic rod is slidably connected to its corresponding spring fixing slide. Each elastic telescopic rod includes a sliding sleeve, and a spring is installed inside the sliding sleeve. One end of the spring is fixed to one end of the elastic telescopic rod, and the other end of the spring is fixed to the central fixing seat. When an external force pulls the elastic telescopic rod, it stretches the spring, causing the elastic telescopic rod to move away from the central fixed seat. When the external force is removed, the spring contracts, causing the elastic telescopic rod to move towards the central fixed seat.

5. The surface alignment assembly system for a compass operating unit according to claim 4, characterized in that, The positioning drive assembly includes a drive gear, which is fixedly connected to the output end of the motor. When the motor rotates, it can drive the drive gear to rotate synchronously. Correspondingly, each of the rotating shafts has a driven gear fixed at the end away from the positioning slider. The driven gear can mesh with the drive gear, and when the drive gear rotates, it can drive the driven gear to rotate synchronously.

6. The surface alignment assembly system for a compass operating unit according to claim 5, characterized in that, The alignment assembly system also includes an automatic pressure application mechanism, which includes a pressure fixing bracket and a pressure fixing base. The pressure fixing base is located below the clamping assembly. The pressure fixing bracket is inserted into the pressure fixing base, and the pressure fixing base is detachable. A pressure application component is rotatably connected to the pressure fixing bracket. The pressure application component includes a pressure plate. A force transmission part is fixed on the top of the pressure plate. The force transmission part has two centrally symmetrical slots. A thrust transmission handle is respectively engaged in each slot. The thrust transmission handle is fixed on a drive gear. The drive gear drives the thrust transmission handle to rotate, thereby driving the pressure plate to rotate to a specific position, at which point the pressure plate can fall vertically from the pressure fixing bracket.

7. A surface alignment assembly method for a compass operating unit, employing the alignment assembly system as described in claim 5, characterized in that, Includes the following steps: S1. Assemble the clamping assembly and place it on the worktable, ensuring its stability; S2. Place the aluminum panel between the positioning support rods of the clamping assembly for clamping, ensuring that the aluminum panel extends horizontally. S3. Assemble the positioning drive assembly and secure the periphery of the surface layer in the gap between each positioning slider and the corresponding rotary release component. S4. Place each positioning slider onto its corresponding positioning support rod, and limit the height of each positioning slider by the positioning piece on the corresponding positioning support rod. S5. Start the motor, drive the drive gear to rotate, and then drive each rotating shaft to rotate through the driven gear. This causes the release ends of each rotating release component on each positioning slider to rotate to the surface layer, releasing the surface layer so that it falls vertically onto the aluminum panel, thus aligning and assembling the surface layer on the aluminum panel. Then, remove the aluminum panel with the correctly assembled surface layer to complete the assembly process.

8. The surface alignment assembly method for a compass operating unit according to claim 7, characterized in that, In step S3, after the periphery of the surface layer is secured in the gap between each positioning slider and the corresponding rotating release component, the automatic pressure mechanism needs to be assembled. The automatic pressure mechanism includes a pressure fixing bracket and a pressure fixing base. The pressure fixing bracket is inserted into the pressure fixing base. First, the pressure fixing base of the automatic pressure mechanism is placed below the clamping assembly, and then the pressure fixing bracket is inserted into the pressure fixing base. A pressure-applying component is rotatably connected to the pressure-applying fixing bracket. The pressure-applying component includes a pressure-applying plate. A force-transmitting part is fixed on the top of the pressure-applying plate. Two centrally symmetrical slots are opened on the force-transmitting part. A thrust transmission handle is respectively engaged in each slot. The thrust transmission handle is fixed on the drive gear. Then continue with step S4, where each positioning slider is fitted onto its corresponding positioning support rod, and the height of each positioning slider is limited by the positioning piece on the corresponding positioning support rod. Then, continuing with step S5, the motor is started, which drives the drive gear to rotate, which in turn drives each rotating shaft to rotate through the driven gear. This causes the release ends of each rotating release component on each positioning slider to rotate to the surface layer, releasing the surface layer so that it falls vertically onto the aluminum panel. The drive gear continues to rotate, which drives the thrust transmission handle to rotate, which in turn drives the pressure plate to rotate to a specific position. The pressure plate falls vertically from the pressure fixing bracket and applies uniform pressure to the front and back layers to ensure that the surface layer is firmly attached to the aluminum panel.
