When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0040] Please see Figures 1 to 11 The caster assembly equipment according to one embodiment of the present utility model includes a machine body 10, an indexing plate 20 installed in the middle of the top surface of the machine body 10, and a first feeding component 30, an oiling component 40, a steel ball feeding component 50, a second feeding component 60, a pressing component 70 and a discharging component 80 arranged sequentially along the periphery of the indexing plate 20.

[0041] Multiple fixtures 21 are evenly spaced along the periphery of the top surface of the indexing plate 20.

[0042] The first feeding assembly 30 includes a first vibratory feeder 31 mounted on one side of the machine body 10 and a first feeding robot 32 mounted at the outlet end of the first vibratory feeder 31; the first feeding robot 32 is located on one side of the indexing plate 20. The first vibratory feeder 31 is used to transport the caster housing 33, and the first feeding robot 32 is used to grip the caster housing 33 of the first vibratory feeder 31 and transfer it into the fixture 21. Specifically, as... Figure 10 As shown, the interior of the caster housing 33 is provided with a circular groove 330 along its circumference.

[0043] The lubrication assembly 40 includes a lubrication support column 41 located on one side of the indexing plate 20, a lubrication linear module 42 mounted on the top of the lubrication support column 41, and a lubricator 43 mounted on the bottom of the lubrication linear module 42; the lubricator 43 is located above the fixture 21. Specifically, the bottom end of the lubricator 43 is connected to two parallel lubrication needles 44, which are used on opposite sides of the slide groove 330. In actual operation, the two lubrication needles 44 extend into the interior of the caster housing 33 to inject lubricating oil into the interior of the slide groove 330.

[0044] The steel ball feeding assembly 50 includes a steel ball supply hopper 51 located on one side of the indexing plate 20, a telescopic rod 52 telescopically installed inside the steel ball supply hopper 51, a steel ball tray 53 coaxially installed at the top of the telescopic rod 52, a steel ball supply cylinder 54 installed on one side of the steel ball supply hopper 51, a steel ball feeding robot 55 installed on the other side of the steel ball supply hopper 51, and a steel ball suction device 56 installed at the end of the steel ball feeding robot 55; the steel ball suction device 56 is correspondingly arranged directly above the steel ball tray 53.

[0045] Specifically, such as Figure 7 As shown, the steel ball tray 53 is arranged in a circular shape, and multiple steel ball positioning cavities 530 are evenly spaced on the top surface of the steel ball tray 53. The steel ball positioning cavities 530 are used to match and accommodate steel balls, so that the steel balls are arranged in an orderly manner, which facilitates the steel ball adsorber 56 to pick them up.

[0046] In this embodiment, as Figure 8 As shown, the steel ball suction device 56 includes an electromagnet 561 mounted on the end of the steel ball feeding robot 55, and a positioning sleeve 562 wrapped around the electromagnet 561. The bottom surface of the positioning sleeve 562 has a circularly arranged positioning groove 563, which corresponds to the steel ball positioning cavity 530. The positioning groove 563 is used to accommodate the steel balls, effectively improving the positional stability of the steel balls during suction and ensuring that the steel balls are transferred to the interior of the chute 330 in an orderly manner. Compared with traditional manual operation, this invention uses a steel ball tray 53 and a steel ball suction device 56, greatly improving the degree of automation, reducing human interference, and effectively increasing overall production capacity.

[0047] In this embodiment, the bottom end of the telescopic rod 52 is inserted into the interior of the machine body 10, and the piston rod of the ball supply cylinder 54 is inserted into the interior of the machine body 10. Inside the machine body 10, the bottom end of the telescopic rod 52 is connected to the piston rod of the ball supply cylinder 54 through an adapter block (not shown), so that the ball supply cylinder 54 can drive the telescopic rod 52 to extend and retract in the vertical direction.

[0048] The second feeding assembly 60 includes a second vibratory feeder 61 installed on one side of the machine body 10, and a second feeding robot 62 installed at the outlet end of the second vibratory feeder 61; the second feeding robot 62 is located on one side of the indexing plate 20. The second vibratory feeder 61 is used to transport the caster inner shell 63, and to grip the caster inner shell 63 and transfer it to the inside of the caster outer shell 33, facilitating the subsequent crimping assembly 70 to fasten the caster inner shell 63 and the caster outer shell 33, allowing relative rotation between them. At this time, steel balls are located between the caster inner shell 63 and the caster outer shell 33, effectively reducing the frictional resistance between them and improving the smoothness of rotation.

[0049] The crimping assembly 70 includes a crimping support 71 located on one side of the indexing plate 20, a crimping cylinder 72 mounted on the top of the crimping support 71, and a crimping head 73 mounted on the bottom of the crimping cylinder 72; the crimping head 73 is located above the fixture 21. After the caster housing 33, steel balls, and caster inner housing 62 are stacked in sequence, the indexing plate 20 rotates to move the stacked caster housing 33, steel balls, and caster inner housing 62 to below the crimping head 73. The crimping head 73 presses the caster inner housing 62 to make it snap onto the caster housing 33, thereby completing the assembly of the entire caster and forming the finished caster.

[0050] The unloading assembly 80 includes a guide ramp 81 located on one side of the indexing plate 20 and an unloading robot 82 mounted on one side of the guide ramp 81; the unloading robot 82 is positioned above the fixture 21. One end of the guide ramp 81 faces inward toward the indexing plate 20, and the other end faces outward toward the collection basket (not shown). The height of the guide ramp 81 gradually decreases from the indexing plate 20 toward the collection basket to create a tilting guiding effect. In actual operation, the unloading robot 82 is used to grab finished casters inside the fixture 21, then places the finished casters onto the guide ramp 81, where they naturally slide down into the collection basket, completing the collection process.

[0051] In this embodiment, the first loading robot 32, the second loading robot 62, and the unloading robot 82 are all two-axis gantry robots.

[0052] The caster assembly equipment described above has a simple structure and is easy to use. The first feeding component 30 and the second feeding component 60 respectively feed the caster outer shell 33 and the caster inner shell 62. The steel ball adsorber 56 and the steel ball tray 53 work together to quantitatively pick up steel balls and place them between the caster outer shell 33 and the caster inner shell 62, which greatly improves the degree of automation, reduces human interference, and effectively improves the overall production capacity.

[0053] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above 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 the 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. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
