[0023] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the needle roller bearing feeding device of this utility model. Figure 2 This is another structural schematic diagram of the needle roller bearing feeding device of this utility model. Figure 3 This is a cross-sectional view of the needle roller bearing feeding device of this utility model. Figure 4 This is a schematic diagram of the structure of the second positioning seat in the needle roller bearing feeding device of this utility model. A needle roller bearing feeding device includes a supporting base plate 1, an inclined slide plate 4, a feeding mechanism 5, and several pushing mechanisms 6. The supporting base plate 1 is provided with a front support 2 and a rear support 3 spaced apart. The two ends of the inclined slide plate 4 are respectively set on the front support 2 and the rear support 3, and the inclined slide plate 4 is inclined downwards along the direction from the rear support 3 to the front support 2. Several slide rails 41 are arranged side by side on the inclined slide plate 4, and a limiting block 42 is provided at the end of each slide rail 41. The feeding mechanism 5 includes a support frame 51 and several guide cylinders 52 for storing needle roller bearings 8. The support frame 51 is set on... On the rear support 3, the support frame 51 is provided with several mounting grooves 511 located on one side of several slides 41, several guide cylinders 52 are respectively installed through several mounting grooves 511, several pushing mechanisms 6 are respectively located on one side of several slides 41 and are installed on the support base plate 1, several pushing mechanisms 6 correspond one-to-one with several slides 41 and one-to-one with several guide cylinders 52, and the pushing mechanism 6 is used to push the needle roller bearing 8 located below the corresponding guide cylinder 52 on the rear support 3 into the corresponding slide 41.

[0024] When using the needle roller bearing 8 feeding device of this utility model, multiple needle roller bearings 8 are fed into the guide cylinder 52 in batches. The needle roller bearings 8 slide naturally in the guide cylinder 52, and the needle roller bearings 8 are coarsely positioned in the guide cylinder 52. Then, the needle roller bearings 8 are guided down by the guide cylinder 52 to the rear support 3. There is a gap between the bottom end of the guide cylinder 52 and the rear support 3. The distance of this gap is equal to the height of one needle roller bearing 8, or the gap is greater than the height of one needle roller bearing 8 but less than the height of two needle roller bearings 8. Then, the pusher mechanism 6 pushes the needle roller bearing 8 on the rear support 3, causing the needle roller bearing 8 to move into the corresponding slide rail 41 after passing through the gap between the support frame 51 and the rear support 3. Due to the inclined slide plate 4, the needle roller shaft is affected by gravity and slides down onto the limiting block 42 guided by the slide rail 41. The slide rail 41 and the limiting block 42 achieve precise positioning, ensuring high precision in feeding the needle roller bearing 8 and ensuring accurate gripping of the needle roller bearing 8 by the robot arm without vision. Several slide rails 41 are set on the inclined slide plate 4, and each guide cylinder 52 corresponds to a slide rail 41. The needle roller bearing 8 in each guide cylinder 52 is fed through the corresponding slide rail 41, avoiding collisions between the needle roller bearings 8 and preventing damage to the quality of the needle roller bearing 8. Furthermore, the several pusher mechanisms 6 are independently controlled and can operate independently, thereby realizing the ejection of one or several needle roller bearings 8 individually.

[0025] In one embodiment, the limiting block 42 has a first V-groove 43 on one end facing the slide 41. The needle roller bearing 8 slides into the first V-groove 43 and is positioned by the first V-groove 43 to ensure the feeding accuracy of the needle roller bearing 8.

[0026] In one embodiment, a display slot 521 is provided on the side of the guide cylinder 52 away from the inclined slide plate 4. The number of needle roller bearings 8 inside the guide cylinder 52 can be viewed through the display slot 521.

[0027] In one embodiment, a first laser sensor 44 is provided on the limiting block 42, and a second laser sensor 53 is provided on the support frame 51 on the side of the guide cylinder 52 away from the display slot 521. A through hole 522 is provided on the guide cylinder 52 corresponding to the position of the second laser sensor 53. The first laser sensor 44 and the second laser sensor 53 can be connected to the control system. The first laser sensor 44 can monitor whether there is a needle roller bearing 8 in the slide 41. If the first laser sensor 44 senses that there is a needle roller bearing 8 in the slide 41, it can transmit the information that there is a needle roller bearing 8 and control the robot arm to pick up the needle roller bearing 8 in the slide 41. If the first laser sensor 44 does not sense that there is a needle roller bearing 8 in the slide 41, it can transmit the information that there is no needle roller bearing 8 and control the corresponding pushing mechanism 6 to push the needle roller bearing 8 into the corresponding slide 41. The through hole 522 is located at the lower part of the guide cylinder 52. The second laser sensor 53 monitors whether there are enough needle roller bearings 8 in the guide cylinder 52. When a second laser sensor 53 detects that there are no needle roller bearings 8 in the through hole 522, it means that the needle roller bearings 8 in the corresponding guide cylinder 52 are almost used up. The system is triggered to issue a "needle roller bearing 8 shortage" signal, reminding the staff or robot to add needle roller bearings 8 to the corresponding guide cylinder 52.

[0028] Please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of the L-shaped pusher plate in the needle roller bearing feeding device of this utility model. In one embodiment, a first positioning seat 7 is provided on the supporting base plate 1, and the rear support 3 includes a feeding base plate 31 and two side plates 32. The two side plates 32 are located on the side of the first positioning seat 7 away from the front support 2 and are spaced apart on the supporting base plate 1. The two ends of the feeding base plate 31 are respectively located at the top of the two side plates 32. The feeding base plate 31 is connected to the inclined slide plate 4. The support frame 51 is provided on the feeding base plate 31. The pushing mechanism 6 includes an L-shaped pusher plate 61 and a cylinder 62. The cylinder 62 is located below the corresponding guide cylinder 52 and is provided on the first positioning seat 7. The L-shaped pusher plate 61 includes a vertical part 611 and a horizontal part 612. The vertical part 611 is connected to the telescopic end of the cylinder 62. A groove 33 is provided on the feeding base plate 31 for the vertical part 611 to pass through and move. The horizontal part 612 is slidably provided on the feeding base plate 31. The feeding base plate 31 receives the needle roller bearings that fall from the guide cylinder 52. Then, the retraction of the telescopic end of the cylinder 62 causes the vertical portion 611 of the L-shaped push plate 61 to move along the corresponding slide groove 33, which in turn moves the horizontal portion 612 of the L-shaped push plate 61. This horizontal portion 612 then pushes the needle roller bearings 8 on the feeding base plate 31 into the corresponding slide rail 41. In one embodiment, a second V-groove 613 is provided on the end of the horizontal portion 612 facing the slide rail 41. The second V-groove 613 restricts the movement direction of the needle roller bearings 8, ensuring that they can be pushed into the corresponding slide rail 41.

[0029] In one embodiment, the width of the horizontal portion 612 is greater than the width of the vertical portion 611. The two ends of the width of the horizontal portion 612 are slidably disposed on the loading base plate 31, and the loading base plate 31 supports the horizontal portion 612, making the movement of the horizontal portion 612 more stable.

[0030] In one embodiment, the support frame 51 includes two guide rail strips 512 disposed at both ends of the top of the loading base plate 31, a second positioning seat 513 disposed on the two guide rail strips 512, and a pressure plate 514 disposed on the second positioning seat 513. A plurality of mounting grooves 511 are respectively disposed on the second positioning seat 513. Guide rail grooves 515 are provided on opposite sides of each guide rail strip 512. One end of the two outermost horizontal portions 612 is slidably disposed within the guide rail grooves 515 of the two guide rail strips 512. The plurality of horizontal portions 612 are divided into several groups of two adjacent portions. The bottom end of the second positioning seat 513 is provided with a plurality of protrusions 516, each protrusion corresponding to one of the groups of horizontal portions 612. The protrusions 516 are slidably disposed with the two horizontal portions 612 in the corresponding group. A space for the needle roller bearing 8 to pass through is formed between the pressure plate 514 and the loading base plate 31. The second positioning seat 513 supports and fixes the guide cylinder 52, creating a height difference between the bottom of the guide cylinder 52 and the feeding base plate 31, and also a height difference between the guide cylinder 52 and the L-shaped push plate 61. These two different height differences ensure accurate material placement of the needle roller bearing 8 and the successful ejection of the L-shaped push plate 61. The height difference between the guide cylinder 52 and the L-shaped push plate 61 is less than the height of one needle roller bearing. The guide rail pressure strip 512 further restricts the movement direction of the two outermost horizontal parts 612. Simultaneously, the protrusion 516 on the second positioning seat 513 restricts the vertical movement of the two corresponding horizontal parts 612, further limiting their movement direction.

[0031] In one embodiment, the guide cylinder 52 is provided with a mounting plate 54, which is disposed on the second positioning seat 513. The guide cylinder 52 is disposed on the second positioning seat 513 via the mounting plate 54, which facilitates the guide cylinder 52 to be disposed through the mounting groove 511 of the second positioning seat 513.

[0032] In one embodiment, the inclined slide plate 4 is provided with multiple spacer bars 45 at intervals, and a slide rail 41 is formed between two adjacent spacer bars 45. By changing the position between the spacer bars 45, compatibility with more sizes and models of needle roller bearings 8 can be achieved, and the specifications of the limiting block 42 and the guide cylinder 52 can be changed simultaneously. The flared design at the front end of the slide rail 41 makes it easier for the needle roller bearing 8 to be pushed into the slide rail 41.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
