Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, and in particular to an assembly tooling for automotive rearview mirrors. Background Technology

[0002] In the assembly process of automotive rearview mirrors, an efficient, precise, and easy-to-operate assembly fixture is crucial for improving assembly quality and production efficiency. Currently, a rearview mirror assembly fixture with publication number CN212947492U has been applied in the automotive rearview mirror assembly field. This fixture includes a base plate, control cabinet, two sets of clamping cylinders, two sets of clamping seats, a column, a pressing cylinder, and a pressure plate. The base plate has four sets of support legs at its bottom for stable support, and the control buttons on the control cabinet facilitate operation. The two sets of clamping cylinders drive the clamping seats to clamp and fix the rearview mirror, while the column, in conjunction with the pressing cylinder and pressure plate, performs the pressing operation. This makes fixing the rearview mirror easier and more secure, improving assembly quality to a certain extent and reducing limitations in its use.

[0003] However, in actual automotive rearview mirror assembly, especially in the assembly of the upper and lower covers, the aforementioned existing technology has significant shortcomings. The tooling lacks a specific design for the proper placement of the upper and lower covers of the rearview mirror to be assembled. In practice, workers need to spend extra time and effort manually adjusting the positions of the upper and lower covers to ensure accurate alignment. This not only increases the complexity and difficulty of the operation but also easily leads to inaccurate assembly positions, thus affecting assembly quality. Furthermore, due to the lack of an effective upper cover fixing and moving device, it is difficult to guarantee the stability and precise positioning of the upper cover when aligning it with the lower cover. Misalignment is prone to occur, leading to assembly failure or the need for repeated adjustments, significantly reducing assembly efficiency and failing to meet the demands of modern automotive production for efficient and precise assembly. Utility Model Content

[0004] The purpose of this utility model is to provide an assembly fixture for automotive rearview mirrors. The fixture's top mounting platform, in conjunction with an electric telescopic rod and clamping plate, can conveniently and securely clamp the lower cover to be assembled. On the fixture's mounting platform, an electric push rod drives the suction shell, and a negative pressure pump uses a negative pressure hole to securely suction the upper cover. A forward and reverse motor drives a rotary table to achieve precise movement of the upper cover. During docking, the electric push rod moves the upper cover downwards and shuts off the negative pressure pump to complete the docking. In the pressing stage, the forward and reverse motor rotates the rotary table, causing the electric cylinder of the pressing component to move the pressing plate downwards, facilitating the pressing of the upper and lower covers. This overall optimization of the assembly process improves automation and assembly quality.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0016] This utility model has at least the following beneficial effects:

[0017] 1. This utility model realizes an assembly fixture for automotive rearview mirrors. The placement seat on the top of the fixture assembly table, together with an electric telescopic rod and a clamping plate, can conveniently and securely clamp the lower cover to be assembled. On the fixture placement table, an electric push rod drives the adsorption shell, and a negative pressure pump uses a negative pressure hole to securely adsorb the upper cover. A forward and reverse motor drives a rotary table to achieve precise movement of the upper cover. During docking, the electric push rod drives the upper cover to move down and turns off the negative pressure pump to complete the docking. In the pressing stage, the forward and reverse motor rotates the rotary table, causing the electric cylinder of the pressing component to drive the pressing plate to move down to conveniently press the upper and lower covers. The overall assembly process is optimized, and the degree of automation and assembly quality are improved.

[0018] 2. Convenient and Stable Clamping Design: This utility model features a dedicated tooling assembly table with a placement seat on top. An electric telescopic rod moves the clamping plate close to the lower cover of the car rearview mirror to be assembled, which is placed on the placement seat, enabling convenient and stable clamping of the lower cover.

Simultaneously, a reversible motor drives the rotary table to rotate, easily moving the adsorbed top cover to the corresponding position on the tooling assembly platform, achieving rapid and precise movement of the top cover and greatly improving assembly efficiency.

[0020] 4. Precise Alignment and Press-fitting: After moving the upper cover to the lower cover position, the electric push rod drives the adsorbed upper cover downwards, and the negative pressure pump is turned off, allowing the upper and lower covers of the car rearview mirror to accurately align. Then, the rotary table is rotated again using a forward and reverse motor, moving the press-fitting assembly to the top of the tooling assembly table. An electric cylinder drives the press-fitting plate downwards, easily pressing the upper and lower covers together. The entire alignment and press-fitting process is simple to operate and highly precise, effectively avoiding errors that may occur with manual operation and ensuring the assembly quality of the car rearview mirror.

[0021] 5. Optimized Overall Assembly Process: Through the aforementioned series of ingenious designs, the assembly fixture of this utility model organically combines the placement, fixing, movement, docking, and pressing of the upper and lower covers of the automotive rearview mirror, forming a complete and efficient assembly process.

[0038] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0039] Please refer to Figures 1 to 7 As shown, an embodiment of the present invention provides a car rearview mirror assembly fixture, including: a workbench 1, a fixture placement platform 2 for placing the upper cover of the car rearview mirror to be assembled is provided on one side of the top of the workbench 1, a fixture assembly platform 3 for placing the lower cover of the car rearview mirror to be assembled is provided on the other side of the top of the workbench 1, and an assembly component 4 for assembling the car rearview mirror is installed on the top of the workbench 1 and at the position between the fixture placement platform 2 and the fixture assembly platform 3.

[0040] The assembly component 4 includes a rotary drive component 401, an adsorption component 402 is installed on one side of the top of the rotary drive component 401, and a press-fit component 403 is installed on the other side of the top of the rotary drive component 401.

[0041] By adopting the above technical solution, the placement seat 3011 on the top of the tooling assembly table 3, together with the electric telescopic rod 3012 and the clamping plate 3013, can conveniently and securely clamp the lower cover to be assembled; on the tooling placement table 2, the electric push rod 4021 drives the adsorption shell 4022, and the negative pressure pump 4024 uses the negative pressure hole 4023 to securely adsorb the upper cover, and the forward and reverse motor 4011 drives the rotary table 4012 to achieve precise movement of the upper cover; during docking, the electric push rod 4021 drives the upper cover to move down and turns off the negative pressure pump 4024 to complete the docking; in the pressing stage, the forward and reverse motor 4011 rotates the rotary table 4012 to make the electric cylinder 4031 of the pressing component 403 drive the pressing plate 4032 to move down to conveniently press the upper and lower covers, thus optimizing the overall assembly process and improving the degree of automation and assembly quality.

[0042] To achieve the rotary drive function, in this embodiment, the rotary drive assembly 401 includes a forward / reverse motor 4011 fixedly connected to the top of the worktable 1, and a rotary table 4012 fixedly connected to the output shaft of the forward / reverse motor 4011. This design enables the forward / reverse motor 4011 to drive the rotary table 4012 to perform forward and reverse movements, thereby providing power for the movement of the adsorption assembly 402 and the pressing assembly 403, realizing the transfer of the top cover and the adjustment of the pressing position, and improving the flexibility and automation of assembly.

[0043] To stabilize and limit the rotation of the rotary table 4012, in this embodiment: a limiting bearing sleeve 4013 is rotatably mounted on the output shaft of the forward and reverse motor 4011. L-shaped limiting rods 4014 are fixedly connected to both sides of the limiting bearing sleeve 4013, and the other end of the L-shaped limiting rods 4014 is fixedly mounted on the top of the worktable 1. The combination of the limiting bearing sleeve 4013 and the L-shaped limiting rods 4014 effectively limits the wobbling and offset of the rotary table 4012, ensuring the stability of the rotary table 4012 during rotation, thereby ensuring the accuracy of the upper cover adsorbed above and subsequent pressing operations, and improving assembly quality.

[0044] To achieve stable adsorption and movement of the rearview mirror cover, in this embodiment: the adsorption assembly 402 includes an electric push rod 4021 fixedly connected to one side of the top of the rotating platform 4012. An adsorption shell 4022 is mounted on the output end of the electric push rod 4021. Several negative pressure holes 4023 are opened at the bottom of the adsorption shell 4022, and a negative pressure pump 4024 is mounted on the side of the adsorption shell 4022. The electric push rod 4021 can drive the adsorption shell 4022 to move up and down, facilitating the adsorption and lowering of the cover placed on the worktable 1. The negative pressure pump 4024 generates negative pressure through the negative pressure holes 4023, which can stably adsorb the cover, preventing it from falling off during movement and ensuring that the cover can be accurately transferred to the position where it docks with the lower cover.

[0045] To facilitate the press-fitting of the upper and lower covers of a car rearview mirror, in this embodiment, the press-fitting assembly 403 includes an electric cylinder 4031 fixedly connected to the other side of the top of the rotary table 4012, and a press-fitting plate 4032 is mounted on the output end of the electric cylinder 4031. The electric cylinder 4031 can provide stable and precise downward pressure, and the press-fitting plate 4032 presses the already mated upper and lower covers together, ensuring a tight fit and robust assembly. Simultaneously, the electric cylinder 4031 offers high control precision, meeting the press-fitting requirements of rearview mirrors of different specifications.

[0046] To facilitate and securely fix the lower cover of the car rearview mirror, in this embodiment, a fixing component 301 for fixing the lower cover is also provided on the top of the tooling assembly table 3. The fixing component 301 includes a placement seat 3011 fixedly connected to the tooling assembly table 3. Electric telescopic rods 3012 are installed on both sides of the placement seat 3011, and clamping plates 3013 are installed on the output ends of the electric telescopic rods 3012. The placement seat 3011 provides a placement position for the lower cover. The electric telescopic rods 3012 drive the clamping plates 3013 to move, which can be flexibly adjusted according to the lower cover of different sizes, realizing convenient and secure clamping of the lower cover, ensuring that the lower cover will not move during the assembly process, and improving the accuracy of assembly.

[0047] To further enhance the stability of the clamping plate 3013's movement, in this embodiment: a limiting telescopic rod 3014 is fixedly connected to the side of the clamping plate 3013, and the other end of the limiting telescopic rod 3014 is fixedly connected to the side of the placement seat 3011. The limiting telescopic rod 3014 can restrict the direction of movement of the clamping plate 3013, preventing it from shifting during movement, ensuring that the clamping plate 3013 can accurately clamp the lower cover, and also enhancing the structural stability of the entire fixing assembly 301.

[0048] The working principle of this utility model is as follows:

[0049] First, place the lower cover of the car rearview mirror to be assembled stably on the placement seat 3011 on the top of the tooling assembly table 3. Then, start the electric telescopic rod 3012. The electric telescopic rod 3012 drives the clamping plate 3013 to move closer to the lower cover. Under the stabilizing effect of the limiting telescopic rod 3014, the clamping plate 3013 accurately and firmly clamps and fixes the lower cover.

[0050] Next, place the car rearview mirror cover to be assembled on the tooling platform 2, turn on the electric push rod 4021, the electric push rod 4021 pushes the adsorption shell 4022 downward to the appropriate position, and then start the negative pressure pump 4024. The negative pressure pump 4024 generates negative pressure inside the adsorption shell 4022, and the cover is firmly adsorbed through the negative pressure hole 4023 at the bottom of the adsorption shell 4022.

[0051] Then, the forward and reverse motor 4011 is started, which drives the rotary table 4012 to rotate. Since the rotary table 4012 is equipped with an adsorption component 402, the adsorption component 402 adsorbing the upper cover will rotate accordingly, accurately moving the upper cover to the position on the tooling assembly table 3 corresponding to the lower cover.

[0052] Once the position is reached, the electric push rod 4021 is activated again to move the adsorbed upper cover downwards. After the upper cover and lower cover are accurately aligned, the negative pressure pump 4024 is turned off to release the adsorption state of the upper cover.

[0053] Then, the forward and reverse motor 4011 is started again, causing the rotary table 4012 to rotate and move the pressing assembly 403 to the top of the tooling assembly table 3. Then, the electric cylinder 4031 is started, and the electric cylinder 4031 drives the pressing plate 4032 to move downward. The pressing plate 4032 applies pressure to the upper cover and the lower cover, pressing the two together conveniently and firmly, thus completing the assembly of the car rearview mirror.
