Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to an automatic feeding device for snap rings. Background Technology

[0002] Currently, many electronic products require the installation of retaining rings during production and assembly. Retaining ring types mainly include shaft retaining rings, bore retaining rings, E-type retaining rings, C-type retaining rings, and U-type retaining rings. Some retaining rings are very thin; for example, E-type retaining rings are typically only 0.7 mm thick. For thinner, smaller retaining rings, manual handling is difficult, often resulting in problems with removal. Furthermore, when assembling the retaining rings, retaining ring pliers are needed to clamp them and press them into the product. Manually clamping the retaining rings into the pliers is difficult, time-consuming, and labor-intensive. Additionally, the sharp ends of the pliers pose a risk of injury to workers' fingers during manual operation. Therefore, an automated device for feeding and clamping retaining rings is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The vibratory feeder can drive the first slide rail to vibrate together, enabling the circlip to move smoothly to the second slide rail. The circlip that slides onto the second slide rail can move sequentially to the side of the second slide rail closest to the mounting base under the action of gravity. A circlip clamp is placed on the mounting base. The circlip located on the side of the second slide rail closest to the mounting base can move along the second slide rail to fall into the circlip clamp, thereby realizing the automatic feeding process of the circlip.

[0031] Many electronic products require the installation of retaining rings during production and assembly. Retaining rings, also known as snap rings or clips, are fasteners primarily used in the grooves and holes of machines or equipment to prevent axial displacement of parts on the shaft or in the hole. They utilize their elastic deformation to achieve fixing, connection, or position adjustment. Retaining rings are made from various materials, commonly stainless steel and spring steel, to meet the needs of different environments. Types of retaining rings mainly include shaft retaining rings, hole retaining rings, E-type retaining rings, C-type retaining rings, and U-type retaining rings. Some types of retaining rings are very thin; for example, the thickness of an E-type retaining ring is typically only 0.7 mm. For thinner, smaller retaining rings, manual removal by hand is difficult and can be challenging. Furthermore, when assembling the retaining rings, retaining ring pliers are needed to clamp them before pressing them into the product. Manually clamping the retaining rings into the pliers is difficult, time-consuming, and labor-intensive. Additionally, retaining ring pliers are needle-nose pliers with sharp, pointed tips that can easily prick an employee's fingers during manual operation. Therefore, an automated device for feeding and clamping retaining rings is a technical problem that urgently needs to be solved by those skilled in the art.

[0032] refer to Figures 1-6 To address the aforementioned issues, this application provides an automatic snap ring feeding device 10, comprising a vibratory feeder 20, a first slide rail 30, a second slide rail 40, and a mounting base 50. The vibratory feeder 20 has a receiving groove 21 for placing snap rings 11. The first slide rail 30 is connected to the vibratory feeder 20 and one end extends into the receiving groove 21. The vibratory feeder 20 can drive the first slide rail 30 to vibrate. The other end of the first slide rail 30 is directly opposite one end of the second slide rail 40. The second slide rail 40 is mounted on the mounting base 50, which is used to place snap ring clamps 12. The cross-sectional shapes of the first slide rail 30 and the second slide rail 40 are adapted to the snap ring groove shape of the snap ring 11 to hold the snap ring 11 and allow the snap ring 11 to move along the first slide rail 30 and the second slide rail 40. The snap ring 11 moves along the second slide rail 40 to fall into the snap ring clamps 12.

[0033] In this automatic snap ring feeding device 10, the device includes a vibratory feeder 20, a first slide rail 30, a second slide rail 40, and a mounting base 50. The vibratory feeder 20 has a receiving groove 21, in which the scattered snap rings 11 are placed. The vibratory feeder 20 is an auxiliary feeding device for automatic assembly or automatic processing machinery, capable of arranging the snap rings 11 in an orderly manner. The vibratory feeder 20 can be made to vibrate vertically by means of a pulse electromagnet or vibration motor at the bottom of the vibratory feeder 20. Specifically, in some embodiments, a pulse electromagnet is provided at the bottom of the vibratory feeder 20, which causes the vibratory feeder 20 to vibrate vertically. The inclined spring plates drive the hopper to torsionally vibrate around its vertical axis. The snap rings 11 in the receiving groove 21 rise along the spiral track due to this vibration. During the ascent, after a series of track selections or attitude changes, the snap rings 11 can automatically enter the assembly or processing position in a uniform state according to the assembly or processing requirements. The vibration of the vibratory feeder 20 enables the snap rings 11 in the receiving slot 21 to be automatically and orderly oriented and accurately transported to the first slide rail 30 and the second slide rail 40. The first slide rail 30 is connected to the vibratory feeder 20. Since the first slide rail 30 is connected to the vibratory feeder 20, the first slide rail 30 can vibrate together with the vibratory feeder 20. The snap rings 11 in a uniform state vibrated by the vibratory feeder 20 are transported to the first slide rail 30. As the vibratory feeder 20 continues to vibrate, the snap rings 11 that have moved to the first slide rail 30 can continue to move along the first slide rail 30 under the vibration of the vibratory feeder 20. At the same time, since the snap rings 11 move from the vibratory feeder 20 to the first slide rail 30 one after another, the compression between adjacent snap rings 11 can also make the snap rings 11 move along the first track towards the second track. The other end of the first slide rail 30 is directly opposite one end of the second slide rail 40. The cross-sectional shapes of the first slide rail 30 and the second slide rail 40 are adapted to the shape of the retaining groove of the retaining spring 11. Therefore, when the retaining spring 11 moves to the other end of the first slide rail 30, it can smoothly enter the second slide rail 40. The movement of the retaining spring 11 on the second slide rail 40 mainly relies on gravity. In some embodiments, the surfaces of the first slide rail 30 and the second slide rail 40 can be made smooth, which is beneficial for the retaining spring 11 to move more smoothly on the first and second tracks. In some embodiments, the dimensions of the vibratory feeder 20, the first slide rail 30, and the second slide rail 40 can be customized according to the model of the retaining spring 11 to be supplied. The second slide rail 40 is mounted on the mounting base 50, which can be used to place the retaining spring pliers 12. The retaining spring pliers 12 are usually shaped like needle-nose pliers and are used to install and remove the retaining spring 11. The pliers 12 have various forms of pliers heads, including straight inside, straight outside, bent inside, and bent outside. The appropriate pliers head is selected according to the type of retaining spring 11 to be installed. The snap ring pliers 12, through their structure and materials, enable the operator to easily install the snap ring 11 into the shaft groove or hole groove of the component, or remove it from these parts.The snap ring clamp 12 can be made of chromium vanadium alloy steel or high carbon steel. Snap ring clamps 12 made of chromium vanadium alloy steel or high carbon steel undergo special heat treatment processes, such as quenching and annealing, to improve their hardness and durability, enabling them to effectively complete their work tasks. Whether installing or removing snap rings, they ensure both efficiency and safety. Furthermore, the snap ring 11, moving from the first slide rail 30 to the second slide rail 40, continues to move away from the vibratory feeder 20 to fall into the snap ring clamp 12, thus achieving an automatic feeding process for the snap ring 11.

[0034] See Figure 3 and Figure 5 The bottom of the receiving groove 21 is provided with an opening 22 and a guide groove. The guide groove is used to enable the snap rings 11 in the vibratory feeder 20 to automatically enter the first slide rail 30 in a uniform state according to the assembly or processing requirements. The guide groove is directly opposite the opening 22. One end of the first slide rail 30 extends into the guide groove through the opening 22. The snap rings 11 arranged in an orderly manner enter the guide groove through the opening 22. The guide groove is adapted to the shape of the snap rings 11 to guide the snap rings 11 and insert them into the first slide rail 30. The snap rings 11 inserted into the first slide rail 30 move on the first slide rail 30. The snap rings 11 are vibrated from the guide groove to the first slide rail 30 in turn. The snap rings 11 that enter the first slide rail 30 later will give a push to the snap rings 11 that entered the first slide rail 30 earlier, so that the snap rings 11 move away from the opening 22 in turn. In some embodiments, the first slide rail 30 is divided into a transverse section 31 and a vertical section 32. The transverse section 31 is connected to the receiving groove 21, and one side of the transverse section 31 extends into the receiving groove 21. The retaining ring 11 entering the first slide rail 30 moves sequentially from the transverse section 31 to the vertical section 32. The cross-sectional shapes of the transverse section 31 and the vertical section 32 are adapted to the retaining groove shape of the retaining ring 11, so that the retaining ring 11 can be locked by the transverse section 31 and the vertical section 32 during movement. The transverse section 31 can be configured as a slide rail with a certain downward curvature. For example, in one embodiment, the transverse section 31 can be configured to tilt downward at 10° towards the side where the transverse section 31 and the vertical section 32 intersect. The tilt angle allows the retaining ring 11 to move smoothly to the vertical section 32 not only by the thrust between the retaining rings 11, but also by a portion of the weight of the retaining ring 11, when moving from the transverse section 31 to the vertical section 32, which is beneficial to improving the moving efficiency of the retaining ring 11. The vertical section 32 is vertically oriented towards the second slide rail 40, and the side of the vertical section 32 closest to the second slide rail 40 is connected to the second slide rail 40, which allows the retaining ring 11, which moves to the junction of the vertical section 32 and the second slide rail 40, to move smoothly to the second slide rail 40.

[0035] See Figure 4 and Figure 10There is a gap 60 between the first slide rail 30 and the second slide rail 40. The gap 60 ensures that the second slide rail 40 does not vibrate with the first slide rail 30. Specifically, the vibrating disk 20 vibrates to move the retaining rings 11 in an orderly manner onto the first slide rail 30. The first slide rail 30 is connected to the vibrating disk 20, so the first slide rail 30 vibrates with the vibrating disk 20. Since the retaining rings 11 need to be clamped by the retaining ring clamps 12 on the side of the second slide rail 40 away from the first slide rail 30, if the second slide rail 40 also vibrates with the first slide rail 30, the second slide rail 40 will also vibrate with the first slide rail 30. If the slide rails 30 vibrate together, it will be difficult for the snap ring clamps 12 to hold the snap ring 11, or the snap ring 11 held by the snap ring clamps 12 may fall off under vibration. Therefore, it is necessary to provide a gap 60 between the first slide rail 30 and the second slide rail 40. The function of the gap 60 is to prevent the second slide rail 40 from vibrating together with the first slide rail 30, which is beneficial to the stability of the snap ring 11 moving onto the second slide rail 40, and thus helps to ensure the operational stability of the snap ring clamps 12 when holding the snap ring 11. Specifically, in some embodiments, the gap 60 between the first slide rail 30 and the second slide rail 40 can be less than 0.7mm. In one embodiment, the gap 60 between the first slide rail 30 and the second slide rail 40 can be 0.7mm. The value of the gap 60 is such that, while ensuring that the second slide rail 40 does not move together with the first slide rail 30 (i.e., the gap 60 provides a certain vibration space for the first slide rail 30), the snap ring 11 on the first slide rail 30 can smoothly enter the second slide rail 40 from the vertical section 32.

[0036] See Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9In some embodiments, the mounting base 50 is provided with a clamping mechanism 70, which can act on the snap ring clamp 12 to clamp the snap ring 11. Specifically, the clamping mechanism 70 includes a first cylinder, a lifting member, and a clamping member 71. The clamping member 71 is connected to the lifting member, which can drive the clamping member 71 to move up and down. The first cylinder drives the clamping member 71 to act on the snap ring clamp 12 to clamp the snap ring 11. Specifically, the snap ring clamp 12 may include a first connecting part and a second connecting part, with the first connecting part connected to the second connecting part. The second connecting part is located near the second slide rail 40. The mounting base 50 is provided with a conveyor belt 90, and a plurality of fixed bases 91 are provided on the conveyor belt 90 for placing the snap ring clamp 12. In some embodiments, the fixed base 91 is provided with a moving mechanism, which is used to drive the snap ring clamp 12 closer to the second slide rail 40. The lifting member and the moving mechanism can cooperate to allow the snap ring clamp 12 to smoothly clamp the snap ring 11. In some embodiments, the fixed base 91 is used to place the first connecting part of the snap ring clamp 12. After the first connecting part is placed, it can be clamped by the clamping member 71, that is, the clamping member 71 is used to clamp the first connecting part to position the snap ring clamp 12. The lifting member can drive the clamping member 71 to rise and fall so as to move the snap ring clamp 12 as needed.

[0037] See Figures 2 to 10The mounting base 50 also includes a positioning mechanism 80, which is located between the clamping member 71 and the second slide rail 40. The positioning mechanism 80 can position the snap ring clamp 12. Specifically, the positioning mechanism 80 clamps the snap ring clamp 12 on the side near the second slide rail 40 to fix the position of the snap ring clamp 12, that is, the positioning mechanism 80 clamps the second connecting part of the snap ring clamp 12 to fix the position of the snap ring clamp 12. In some embodiments, the positioning mechanism 80 includes a second cylinder 81, a first positioning part 82, and a second positioning part 83. The first positioning part 82 and the second positioning part 83 are symmetrically arranged. The second cylinder 81 drives the first positioning part 82 and the second positioning part 83 to move. When the first positioning part 82 and the second positioning part 83 move toward one side of the second connecting part of the snap ring clamp 12, the first positioning part 82 and the second positioning part 83 clamp the second connecting part of the snap ring clamp 12 to position the snap ring clamp 12. When the first positioning part 82 and the second positioning part 83 move away from the second connecting part of the snap ring clamp 12, the first positioning part 82 and the second positioning part 83 release the second connecting part of the snap ring clamp 12. At this time, the second cylinder 81 can drive the first positioning part 82 and the second positioning part 83 to move downward so that the snap ring clamp 12 clamped to the snap ring 11 moves to the unloading position. In some embodiments, the first positioning part 82 and the second positioning part 83 are respectively provided with grooves. When the first positioning part 82 and the second positioning part 83 clamp the second connecting part of the snap ring clamp 12, the groove can engage with the second connecting part, further improving the positioning of the snap ring clamp 12 and improving the stability of the snap ring clamp 12 when clamping the snap ring 11. The first positioning part 82 and the second positioning part 83 clamp the snap ring clamp 12 and apply force to the snap ring clamp 12 to make the snap ring 11 engage in the snap ring clamp 12. The snap ring clamp 12 is provided with a snap-fit ​​position that matches the snap ring 11. After the snap ring 11 is engaged by the snap ring clamp 12, due to the characteristics of the snap ring clamp 12 itself, the snap ring 11 can be held by the snap ring clamp 12 and will not fall off on its own. The clamping member 71, the first positioning part 82, and the second positioning part 83 all position the snap ring clamp 12. The difference lies in that the clamping member 71 can fix the snap ring clamp 12, which moves on the conveyor belt, to ensure that the snap ring clamp 12 will not fall off during its movement on the conveyor belt 90. Simultaneously, when the snap ring clamp 12 clamps the snap ring 11, the clamping member 71 also serves to position the snap ring clamp 12. The first positioning part 82 and the second positioning part 83 are used to position the snap ring clamp 12 when it clamps the snap ring 11. Because when the snap ring clamp 12 clamps the snap ring 11, the snap ring 11 needs to be engaged with the corresponding snap ring interface of the snap ring clamp 12. Therefore, the position where the snap ring clamp 12 clamps the snap ring 11 can be set according to equipment or operational requirements to ensure clamping efficiency. In this case, the positioning device helps to accurately move the snap ring clamp 12 to the position where it clamps the snap ring 11.

[0038] When the automatic spring clip feeding device 10 is working, the scattered spring clips 11 are first placed in the receiving groove 21 of the vibratory feeder 20. Under the action of the vibratory feeder 20, the spring clips 11 can be conveyed to the first slide rail 30 in a uniform state according to the assembly or processing requirements. The spring clips 11 that have moved to the first slide rail 30 can continue to move along the first slide rail 30 under the vibration of the vibratory feeder 20. At the same time, since the spring clips 11 move from the vibratory feeder 20 to the first slide rail 30 one after another, the compression between adjacent spring clips 11 can also make the spring clips 11 move along the first track towards the second track. The other end of the first slide rail 30 is directly opposite one end of the second slide rail 40. The cross-sectional shape of the first slide rail 30 and the second slide rail 40 is adapted to the shape of the groove of the spring clip 11. Therefore, when the spring clip 11 moves to the other end of the first slide rail 30, it can smoothly enter the second slide rail 40. The movement of the spring clip 11 on the second slide rail 40 mainly relies on gravity. Furthermore, a gap 60 exists between the first slide rail 30 and the second slide rail 40. This gap 60 ensures that the second slide rail 40 does not vibrate together with the first slide rail 30, which helps stabilize the snap ring 11 as it moves onto the second slide rail 40, thereby ensuring operational stability when the snap ring clamp 12 grips the snap ring 11. Furthermore, the snap ring 11 moves sequentially onto the second slide rail 40. Furthermore, the mounting base 50 is equipped with a clamping mechanism 70, which includes a first cylinder, a lifting component, and a clamping component 71. The clamping mechanism 70 acts on the snap ring clamp 12 to clamp the snap ring 11. The clamping component 71 is fixed to the snap ring clamp 12, which moves on the conveyor belt, ensuring that the snap ring clamp 12 does not fall off during its movement on the conveyor belt 90. Simultaneously, when the snap ring clamp 12 grips the snap ring 11, the clamping component 71 also positions the snap ring clamp 12. The lifting component and the moving mechanism work together to move the snap ring clamp 12 to the position where the snap ring 11 needs to be clamped. This position can be set according to equipment and operational requirements. Furthermore, the first positioning part 82 and the second positioning part 83 are used to position the snap ring clamp 12 when it clamps the snap ring 11. Because the snap ring 11 needs to be engaged with the corresponding snap ring interface of the snap ring clamp 12 when it clamps the snap ring 11, the position where the snap ring clamp 12 clamps the snap ring 11 can be pre-set to ensure clamping efficiency. In this case, the positioning device helps to accurately move the snap ring clamp 12 to the position where the snap ring 11 is clamped. When the first positioning part 82 and the second positioning part 83 move toward one side of the second connecting part of the snap ring clamp 12, the first positioning part 82 and the second positioning part 83 clamp the second connecting part of the snap ring clamp 12 to position the snap ring clamp 12. At this time, the first positioning part 82 and the second positioning part 83 clamp the snap ring clamp 12 and apply force to the snap ring clamp 12 so that the snap ring 11 is inserted into the snap ring clamp 12.The snap ring clamp 12 is provided with a snap-fit ​​position that matches the snap ring 11. After the snap ring 11 is snapped by the snap ring clamp 12, due to the characteristics of the snap ring clamp 12 itself, the snap ring 11 can be held by the snap ring clamp 12 and will not fall off on its own. When the first positioning part 82 and the second positioning part 83 move away from the second connecting part of the snap ring clamp 12, the first positioning part 82 and the second positioning part 83 release the second connecting part of the snap ring clamp 12. At this time, the first positioning part 82 and the second positioning part 83 can be driven to move downward by the second cylinder 81, so that the snap ring clamp 12, which is holding the snap ring 11, moves to the unloading position under the drive of the conveyor belt 90. When the snap ring 11 needs to be clamped again, when the snap ring clamp 12 moves to the set clamping position, the first positioning part 82 and the second positioning part 83 can move upward to the designated position to achieve positioning of the snap ring clamp 12. The above process can realize automatic feeding of the snap ring 11 and improve the working efficiency of the snap ring 11 feeding.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
