Description

Technical Field

[0001] This utility model relates to the field of snap ring assembly technology, and specifically to an automatic snap ring assembly device. Background Technology

[0002] The existing automotive air supply unit drying chamber requires two retaining rings. The assembly of these inner retaining rings has always been a challenge because they are generally highly elastic with a small wire diameter, making them difficult to clamp and compress, and hard to press into the designated inner retaining grooves. Therefore, assembly is usually done manually using specialized tools. However, manual assembly is labor-intensive, causing wrist fatigue for workers, and has low efficiency. The assembled products also exhibit poor consistency and reliability, lack automated control, and are difficult to integrate into automated production lines.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Example 1, as Figures 1-10As shown in the figure, this embodiment describes in detail an automatic snap ring assembly device. This utility model can effectively realize the automatic assembly of snap rings in the drying chamber of an automotive air supply unit, improve assembly efficiency, and unify assembly quality.

[0022] The automatic snap ring assembly device of this utility model includes a material conveying device 1, a material lifting device 2, an equipment support 3, a snap ring feeding device 4, a snap ring guiding device 5, and a snap ring mounting device 6. The material conveying device 1 includes a conveyor belt 11 and a material conveying plate 12. A product detection sensor 13 is provided on one side of the conveyor belt 11, and an automotive air supply unit 14 is fixed on the material conveying plate 12. The material lifting device 2 is used to control the material conveying plate 12 to move to the installation position. The equipment support 3 includes four support rods 31. A lower support plate 32 and an upper support plate 33 are provided between the support rods 31; a snap ring feeding device 4 is provided on the lower support plate 32, including a snap ring storage mechanism 41 and a snap ring pushing mechanism 42; a snap ring guiding device 5 is provided on the lower support plate 32 for compressing and guiding the snap ring 7; a snap ring mounting device 6 is provided on the upper support plate 33, including a moving mechanism 61 and a snap ring pressing head 62, the moving mechanism 61 controls the snap ring pressing head 62 to push the snap ring 7 from the snap ring guiding device 5 into the drying chamber 140 of the automotive air supply unit 14.

[0023] Specifically, such as Figure 1 As shown in Figure 2, the equipment bracket 3 serves as the support structure for the entire device and consists of four support rods 31 arranged in a rectangular shape. Between the four support rods 31, a lower support plate 32 and an upper support plate 33 are arranged sequentially from bottom to top, serving as a mounting platform for other components.

[0024] The material conveying device 1 is located below the equipment support 3. The conveyor belt 11 passes through the gap of the support rod 31. The material lifting device 2 is installed below the material conveying plate 12 and is used to control the lifting of the material conveying plate 12. The snap ring feeding device 4 and the snap ring guiding device 5 are set on the lower support plate 32. The snap ring mounting device 6 is set on the upper support plate 33.

[0025] The automotive air supply unit 14 is snapped into the limiting groove 120 of the material conveying plate 12, ensuring that the automotive air supply unit 14 is accurately positioned and securely fixed. The automotive air supply unit 14 has two drying chambers 140, corresponding to the positions of the two guide cone sleeves 51. The conveyor belt 11 is started, driving the material conveying plate 12 to move. A product detection sensor 13, located on one side of the conveyor belt 11, continuously monitors the material conveying plate 12 for the presence of the automotive air supply unit 14. When the automotive air supply unit 14 is detected to have reached the designated position, the conveyor belt 11 stops, and the automotive air supply unit 14 is now in the assembly-ready position.

[0026] The material lifting device 2 uses a lifting cylinder 21, and a top plate 22 is provided on the telescopic rod of the lifting cylinder 21. When the vehicle air supply unit 14 arrives at the assembly station, the lifting cylinder 21 is activated, the telescopic rod extends upward, and the top plate 22 abuts against and supports the material conveying plate 12, moving the material conveying plate 12 together with the vehicle air supply unit 14 to the installation position, so that the drying chamber 140 is engaged with the locking interface 511 at the lower end of the guide cone sleeve 51, which facilitates the assembly of the retaining spring 7.

[0027] like Figures 4-6 As shown: In the snap ring storage mechanism 41, a snap ring through hole 410 is provided between two symmetrically arranged storage mounting seats 411. A snap ring mounting plate 412 is provided on one of the storage mounting seats 411, and a guide block 413 is connected to the snap ring mounting plate 412. A snap ring storage rod 414 is provided on one side of the guide block 413, and the lower end of the snap ring storage rod 414 is located in the snap ring through hole 410.

[0028] The open ends of the snap rings 7 face the guide block 413 in sequence. Several snap rings 7 are then placed on the snap ring storage rod 414 in sequence. Under the action of gravity, the snap rings 7 fall naturally into the snap ring through hole 410 and are arranged in sequence above the snap ring push groove 420, thereby realizing the automatic feeding of snap rings 7.

[0029] The number of retaining rings is detected by a retaining ring detection sensor 415 installed on another storage mounting base 411. The retaining ring detection sensor 415 detects the height of the retaining rings 7 on the retaining ring storage rod 414 in real time. When the number of retaining rings is lower than the set height value, an alarm signal is issued to remind the operator to replenish the retaining rings in time to ensure the continuity of the feeding process.

[0030] like Figure 5-6 As shown, a movable push plate 422 is installed above the push mounting plate 421 of the snap ring pushing mechanism 42, and a push cylinder 423 is fixed below it. A synchronization plate 424 is installed on the telescopic rod of the push cylinder 423, and the upper end of the synchronization plate 424 is fixed on the movable push plate 422. A snap ring push groove 420 is provided at the front end of the movable push plate 422. The depth of the snap ring push groove 420 is the same as the thickness of a single snap ring 7, which is used to store one snap ring 7 ready for loading. A buffer assembly 425 is provided at the rear end. When the push cylinder 423 is activated, the telescopic rod extends, and the movable push plate 422 moves forward through the synchronization plate 424, pushing the snap ring 7 in the snap ring through hole 410 into the snap ring push groove 420, completing one snap ring loading preparation. The buffer assembly 425 is used to buffer the push cylinder 423 to prevent the push cylinder 423 from using excessive force.

[0031] like Figure 4 , Figure 6 and Figure 7As shown, the snap ring guide device 5 includes two guide cone sleeves 51 corresponding to the drying chamber 140. The diameter of the guide cone sleeves 51 gradually decreases from top to bottom, and a snap-fit ​​interface 511 is provided at the lower end. During installation, the guide cone sleeves 51 are snapped and fixed to the drying chamber 140 of the vehicle air supply unit 14 through the snap-fit ​​interface 511. When the snap ring pressure head 62 pushes the snap ring 7 from the upper end of the guide cone sleeve 51, it slowly moves to the lower end of the guide cone sleeve 51. Under the conical guidance of the guide cone sleeve 51, the snap ring 7 is gradually compressed until it enters the drying chamber 140 and then returns to its original shape. At the same time, the diameter of the snap ring 7 is larger than the diameter of the snap-fit ​​interface 511.

[0032] like Figures 8-10 As shown, the upper support plate 33 is equipped with a snap ring mounting device 6. The moving mechanism 61 of the snap ring mounting device 6 includes a transverse pushing cylinder 611 and a transverse moving plate 612. A movable connecting plate 613 is provided on the telescopic rod of the transverse pushing cylinder 611, and the other end of the movable connecting plate 613 is fixed to the transverse moving plate 612. A transverse moving slide rail 614 is provided at the lower end of the transverse moving plate 612, and multiple transverse moving sliders 615 are provided between the transverse moving plate 612 and the transverse moving slide rail 614. There are two moving slide rails 614, which are fixed parallel to each other on the upper support plate 33.

[0033] When the transverse push cylinder 611 is activated, the telescopic rod extends and drives the transverse moving plate 612 to move laterally along the transverse moving slide rail 614 via the moving connecting plate 613, thereby moving the snap ring pressure head 62 to pick up the snap ring and move it directly above the two guide cone sleeves 51 respectively.

[0034] like Figure 9 As shown, a vertical moving device 63 is installed on the horizontal moving plate 612. A vertically movable pressure plate 632 is installed on the telescopic rod of the vertically movable cylinder 631 of the vertical moving device 63. Movable guide rods 633 are installed on both sides of the upper surface of the vertically movable pressure plate 632. Guide sleeves 634 are installed on both sides of the vertically movable cylinder 631, and each movable guide rod 633 is located in the corresponding guide sleeve 634. The snap ring pressure head 62 is fixed below the vertically movable pressure plate 632. When the vertically movable cylinder 631 is activated, the telescopic rod extends, driving the vertically movable pressure plate 632 to move downward. The movable guide rods 633 slide within the guide sleeves 634 to ensure smooth movement of the vertically movable pressure plate 632. The snap ring pressure head 62 moves downward together with the vertically movable pressure plate 632, pressing the snap ring 7 in the guide cone sleeve 51 into the drying chamber 140 of the automotive air supply unit 14.

[0035] like Figure 10As shown, a magnet 621 is positioned below the retaining ring pressure head 62. When the retaining ring pressure head 62 moves downwards to contact the retaining ring 7, the magnet 621 generates a magnetic force to attract the retaining ring 7, making the retaining ring 7 fit more tightly against the retaining ring pressure head 62. This ensures that the retaining ring 7 will not fall off during assembly, improving the accuracy and reliability of assembly. It also reduces the need for gripping equipment and simplifies the equipment structure.

[0036] After one circlip assembly is completed, the vertical moving cylinder 631 and the horizontal pushing cylinder 611 reset sequentially, causing the circlip pressure head 62 to return to its initial position. The pushing cylinder 423 resets, and the movable push plate 422 returns to its original position, ready for the next circlip loading. The telescopic rod of the lifting cylinder 21 retracts, the top plate 22 descends, and the material conveying plate 12 returns to the conveyor belt 11. The conveyor belt 11 continues to run, transporting the assembled automotive air supply unit 14 to the next process, while simultaneously transporting new automotive air supply units 14 to be assembled to the assembly station, starting a new assembly cycle.

[0037] Working principle: First, the conveyor belt 11 transports the automotive air supply unit 14 on the material conveying plate 12 to the designated position. When the product detection sensor 13 on the conveyor belt 11, i.e., the photoelectric sensor, detects a product, the conveyor belt 11 stops. At the same time, the lifting cylinder 21 starts the telescopic rod to extend, driving the top plate 22 to lift the entire material conveying plate 12 and align the two drying chambers 140 with the two guide cone sleeves 51 respectively. At the same time, the entire equipment starts the automatic material distribution and pressing spring program. If no product is detected, the material conveying plate 12 flows directly to the next process. Then, after the snap ring detection sensor 415 on the snap ring storage mechanism 41 senses that there is a snap ring 7 in the snap ring storage rod 414, it pushes the cylinder 423 to move. The movable push plate 422 pushes out one snap ring. After the cylinder 423 reaches the designated position, the vertical movable cylinder 631 on the upper support plate 33 drives the vertical movable pressure plate 632 to move down to pick up the snap ring 7. The snap ring 7 is attracted to the snap ring pressure head 62 by the magnet 621 on the snap ring pressure head 62. The movable push plate 422 retracts to the initial position. At the same time, the snap ring 7 on the snap ring storage rod 414 falls down under the action of gravity. The bottommost snap ring 7 is in the snap ring push groove 420. Next, the lateral moving cylinder 611 drives the lateral moving plate 612 to move, causing the entire vertical moving device 63 to move. This causes the retaining spring pressure head 62 to move the retaining spring 7. After moving to a position above one of the guide cone sleeves 51, the vertical moving cylinder 631 on the upper support plate 33 drives the vertical moving pressure plate 632 to move downward, pushing the retaining spring 7 to move and compress within the guide cone sleeve 51 until the retaining spring 7 passes through the retaining interface 511 and enters the drying chamber 140. The guide cone sleeve 51 has a conical structure with a large opening at the entrance and a small opening at the bottom. As the vertical moving cylinder 631 moves downward, the retaining spring 7 is gradually compressed. After reaching the vehicle air supply unit 14, the retaining spring rebounds and opens again, thus installing the retaining spring into the first drying chamber 140 of the vehicle air supply unit 14.

[0038] Repeat the above operation, and then install the second retaining ring 7 into the second drying chamber 140 of the vehicle air supply unit 14. After the pressing is completed, each mechanism returns to the starting position to prepare for the next pressing of the vehicle air supply unit 14.

[0039] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0040] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
