Description

Technical Field

[0001] This utility model belongs to the technical field of automotive sun visor assembly equipment, and relates to an automatic assembly device for sun visor pin springs. Background Technology

[0002] In the industrial assembly process of automotive sun visors, installing the pins connecting the mirror frame and the mirror cover, and assembling the spring clips between the mirror frame and the mirror cover are two critical and closely related processes. Under current technology, these two processes need to be separated into different workstations or completed manually in steps: operators must first install the pins one by one at a designated workstation, then move the sun visor to another workstation or wait for the tooling to be adjusted at the same workstation before assembling the spring clips. There are significant waiting or transfer gaps between processes. This separate operation not only prolongs the assembly cycle of a single sun visor, leading to low overall production efficiency, but also requires more manpower to monitor the connection between processes. Furthermore, multiple transfers or workstation switches can easily cause positioning deviations in the sun visor, increasing the risk of assembly defects such as pin misalignment and spring clip misalignment, making it difficult to guarantee quality stability during mass production and failing to meet the demands of large-scale, high-precision production of automotive parts.

[0003] For example, a Chinese patent discloses an automatic assembly equipment for automotive sun visor mirror components [application number: 202110888454.7], which includes a material feeding and hot-melt station, a material feeding robot, and a rotary table. The material feeding robot is set between the material feeding and hot-melt station and the rotary table to transfer the components of the material feeding and hot-melt station to the rotary table. On both sides of the rotary table are arranged in sequence: a buffer pad assembly station, a spring assembly station, a spring oiling station, a bulb installation station, a lens cleaning station, a mirror cover closing station, a pin installation station, and a lamp inspection and unloading station. A material unloading conveyor belt is set outside the lamp inspection and unloading station. Summary of the Invention

This solves the problems of difficult positioning of traditional spring assembly and asynchronous operation with pin assembly, and improves the overall assembly efficiency.

[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0019] Figure 1 This is the front view of this utility model; Figure 2 This is a partial structural schematic diagram of the present invention; Figure 3 yes Figure 2 Enlarged diagram of point A in the middle. Detailed Implementation

[0020] like Figures 1-3As shown, an automatic assembly device for sun visor pins and springs includes a base 1, on which a tooling base 2 and a gantry frame 3 are provided. The tooling base 2 is located on the front side of the gantry frame 3. The top of the tooling base 2 is recessed inward to provide a sun visor mounting groove 4 for placing the sun visor. The middle of the gantry frame 3 is provided with a sun visor fixing mechanism 5 located directly above the sun visor mounting groove 4. The base 1 is also provided with a pin assembly mechanism 6 and a spring assembly mechanism 7 for assembling pins and springs into the sun visor placed in the sun visor mounting groove 4.

[0021] In this utility model, by setting a tooling base, a gantry frame, and a pin assembly mechanism and a spring assembly mechanism on the base, the assembly operations of pins and springs can be carried out simultaneously at the same workstation. The sun visor fixing mechanism can firmly fix the mirror frame and mirror cover that make up the sun visor, ensuring the stability of the assembly process. By using the pin assembly mechanism and the spring assembly mechanism to complete the assembly of pins and springs, the efficiency problem caused by the separation of traditional processes is solved, and the overall efficiency of sun visor assembly is improved.

[0022] Specifically, the pin assembly mechanism 6 includes two pin mounting seats 8 symmetrically arranged along the centerline of the tooling base 2. The pin mounting seats 8 are fixed to the top of the tooling base 2 near the gantry 3. Each pin mounting seat 8 has a pin mounting groove, and the inner side of the pin mounting groove has a horizontally penetrating pin discharge hole 9. The outer side of the pin mounting groove has a corresponding ejector hole. The side of the tooling base 2 is provided with a pin ejection assembly 10 that ejects the pins from the pin mounting groove through the pin discharge hole 9. The pin assembly mechanism uses symmetrically arranged pin mounting seats, in conjunction with the pin ejection assembly, to precisely eject the pins from the pin discharge hole to the pin mounting position between the lens cover and the lens frame through the ejector hole. This structural design ensures precise pin assembly positioning and convenient operation, solving the problems of inaccurate positioning and cumbersome operation in traditional pin assembly, and improving the accuracy and efficiency of pin assembly.

[0023] Specifically, the back of the pin mounting base 8 is also inclinedly provided with a storage base 12 having a storage trough 11, the bottom of which is connected to the pin mounting groove. The inclined arrangement of the storage base and the connection between the storage trough and the pin mounting groove enable automatic pin replenishment. The storage trough can hold a certain number of pins. After a pin in the pin mounting groove is ejected, the pins in the storage trough can be automatically replenished to the pin mounting groove under the action of gravity, reducing the frequency of manual pin addition and improving the continuity of assembly.

[0024] Specifically, a pusher cylinder 13 is fixedly connected to the side of the storage base 12 away from the tooling base 2. The output shaft of the pusher cylinder 13 is inserted into the storage base 12 and can push the pins at the bottom of the storage trough 11 into the pin mounting slot. The pusher cylinder can push the pins at the bottom of the storage trough into the pin mounting slot, ensuring that the pins can be accurately and timely replenished to the assembly position. This design solves the problem of untimely pin replenishment or jamming that may occur if gravity is used alone, ensuring smooth pin assembly and further improving assembly efficiency.

[0025] Specifically, the top of the pin mounting base 8 is also detachably fixed with a top cover 14 by several bolts. The detachable top cover of the pin mounting base facilitates the cleaning and maintenance of the pin mounting slot. When the pin is stuck or there is debris in the mounting slot, the top cover can be quickly removed for processing, avoiding excessive downtime due to maintenance difficulties and ensuring the continuous and stable operation of the device.

[0026] Specifically, the pin ejection assembly 10 includes a first ejector cylinder 15. The output shaft end of the first ejector cylinder 15 is connected to a pin ejector pin 16 via a first connecting seat. The pin ejector pin 16 can be horizontally inserted into the ejector pin hole. The pin ejection assembly uses the first ejector cylinder to drive the pin ejector pin, which can stably and reliably eject the pin from the pin discharge hole. The cylinder drive method provides controllable force and precise ejection action, solving the problem of unstable pin assembly quality caused by uneven force in traditional manual ejection or other drive methods, and improving the consistency of pin assembly.

[0027] Specifically, the spring assembly mechanism 7 includes two spring mounting seats 17 symmetrically arranged along the centerline of the tooling base 2. Each spring mounting seat 17 has a spring mounting groove 18 with a T-shaped cross-section. The spring mounting seat 17 is located between two pin mounting seats 8 and is situated on the rear side of the tooling base 2. A spring assembly groove 19 connecting the spring mounting groove 18 and the sun visor mounting groove 4 is located on the rear side of the tooling base 2. A spring ejection assembly 20 is located on the side of the spring mounting seat 17 furthest from the tooling base 2. The symmetrical arrangement of the spring mounting seats and the T-shaped cross-section of the spring mounting groove, combined with the spring assembly groove and the spring ejection assembly, achieve precise spring assembly. The spring mounting seats are located between the two pin mounting seats, ensuring a reasonable layout for spring and pin assembly, allowing for simultaneous operation. This solves the problems of difficult positioning and asynchronous operation with pin assembly in traditional spring assembly, thus improving overall assembly efficiency.

[0028] Specifically, the spring ejection assembly 20 includes a second ejector cylinder 21. The output shaft end of the second ejector cylinder 21 is connected to a spring ejector rod 22 via a second connecting seat. The spring ejector rod 22 can be inserted into the spring mounting groove 18 from the ejector rod hole 23 on the side of the spring mounting groove 18 away from the spring assembly groove 19. The spring ejection assembly uses the second ejector cylinder to drive the spring ejector rod, which can accurately push the spring from the spring mounting groove through the spring assembly groove to the spring mounting position on the sun visor. The cylinder drive ensures stable ejection force and stroke, making the spring assembly position accurate. This solves the problem of poor assembly caused by insufficient pushing force or deviation during spring assembly, and improves the quality of spring assembly.

[0029] Specifically, a positioning platform 24, adapted to the sun visor, protrudes from the sun visor mounting groove 4. The positioning platform within the sun visor mounting groove is adapted to the sun visor; the outer ring of the positioning platform is used for placing the mirror frame, and the portion of the sun visor mounting groove located on the upper part of the positioning platform is used for placing the mirror cover. During assembly, this prevents displacement of the sun visor, ensuring that the pins and springs are accurately installed in the preset positions. This solves the assembly deviation problem caused by unstable placement of traditional sun visors and improves assembly accuracy.

[0030] Specifically, the sun visor fixing mechanism 5 includes a pressing cylinder 25 vertically fixed to the front side of the gantry frame 3. A pressing plate 26 is fixedly connected to the output shaft end of the pressing cylinder 25, and a soft padding layer 27 is provided at the bottom of the pressing plate 26. The pressing cylinder of the sun visor fixing mechanism drives the pressing plate, which, in conjunction with the soft padding layer at the bottom of the pressing plate, can firmly press the sun visor during assembly, while avoiding damage to the sun visor. The soft padding layer acts as a buffer, preventing scratches or deformation of the sun visor surface caused by hard contact. This solves the problem that traditional fixing methods may damage the sun visor, ensuring the assembly quality of the sun visor.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
