Figure 1-Figure 6 As shown, the utility model discloses a needle roller assembly detection mechanism.
[0032] The needle roller assembly detection mechanism includes: a moving mechanism 1, a pick-up and placement device 2 installed at the driving end of the moving mechanism 1, a turntable 3 for conveying gears, a material box 4 for placing needle rollers, a top column 5 installed at intervals at the entrance of the material box 4, a shooting mechanism 6 with the shooting end facing the needle roller, and a guide mechanism 7 installed on the turntable 3.
[0033] The moving mechanism 1 drives the pick-and-place device 2 to move horizontally and vertically. The top column 5 is arranged above the material box 4. The pick-and-place device 2 is located above the top column 5. The shooting mechanism 6 is located in front of the material box 4, and the flow table 3 is located behind the material box 4. The guide mechanism 7 is located above the flow table 3.
[0034] The moving mechanism 1 drives the pick-and-place device 2 to approach the push column 5 , and the push column 5 pushes into the clamping end of the pick-and-place device 2 , and the roller needle falls into the material box 4 .
[0035] The moving mechanism 1 drives the pick-and-place device 2 to approach the photographing mechanism 6, and the photographing mechanism 6 photographs the needle roller to determine whether the needle roller length is qualified. If it is unqualified:
[0036] The moving mechanism 1 drives the pick-and-place device 2 to move above the top column 5 and move downward. The top column 5 pushes into the clamping end of the pick-and-place device 2, and the clamping end of the pick-and-place device 2 moves upward to release the clamping needle roller, and the needle roller falls into the material box 4.
[0037] If qualified:
[0038] The moving mechanism 1 drives the pick-and-place device 2 to move above the guide mechanism 7 and move downward. The guide mechanism 7 limits the clamping end of the pick-and-place device 2, and the clamping end of the pick-and-place device 2 moves upward to release the clamping needle roller, and the needle roller falls into the gear on the turntable 3.
[0039] Whether the needle roller is qualified can be determined by photographing the needle roller through the photographing mechanism 6. According to the determination result, the moving mechanism 1 moves the picking and placing device 2 to different positions, and the unqualified needle roller falls into the material box 4 through the top column 5, and the qualified needle roller falls into the gear through the guide mechanism 7.
[0040] The push column 5 pushes into the clamping end of the pick-up and placement device 2, and the unqualified needle rollers can be taken out and dropped into the material box 4. The guide mechanism 7 restricts the clamping end of the pick-up and placement device 2, and the qualified needle rollers fall into the gear, making the roller needle assembly efficiency and the unqualified needle roller recovery efficiency higher.
[0041] The clamping end of the pick-and-place device 2 picks up and puts down all the rollers of the gear at one time. Compared with placing and picking up one by one, the assembly efficiency of the rollers is higher.
[0042] The moving mechanism 1 comprises: a bracket 11 and a moving module 12 arranged on the bracket 11 along the moving direction of the pick-and-place device 2. The pick-and-place device 2 is installed at the driving end of the moving module 12.
[0043] Exemplarily, there are multiple groups of mobile modules 12. The mobile modules 12 may be mobile modules driven by motors or by cylinders. The mobile modules 12 include guide rails. The pick-and-place device 2 may be moved smoothly by the guide rails.
[0044] The pick-and-place device 2 includes: a space 24, a pick-and-place bracket 21 installed on the driving end of the moving module 12 in the vertical direction, a pick-and-place rod 22 rotatably arranged on the pick-and-place bracket 21 in the vertical direction, and a pick-and-place block 23 movably arranged at the lower end of the pick-and-place bracket 21 in the horizontal direction.
[0045] A through hole is formed in the middle of the pick-and-place block 23. The lower end of the pick-and-place rod 22 passes through the through hole of the pick-and-place block 23. The space 24 accommodates the needle roller. The space 24 is provided between the pick-and-place rod 22 and the pick-and-place block 23. Exemplarily, there are multiple groups of spaces 24. A plurality of spaces 24 are formed between the through hole of the pick-and-place block 23 and the pick-and-place rod 22. The needle roller is placed in the space 24.
[0046] The pick-and-place device 2 further includes: a fourth power device 27 for driving the pick-and-place rod 22 to rotate. Exemplarily, the fourth power device 27 is a motor. The fourth power device 27 is mounted on the pick-and-place bracket 21, and the driving end of the fourth power device 27 is connected to the pick-and-place rod 22. By driving the pick-and-place rod 22 to rotate, the position of the space 24 and the needle roller can be changed, so that the needle roller can be smoothly inserted into the gear.
[0047] The pick-and-place block 23 is connected to the pick-and-place bracket 21 through the rod body 25. The upper end of the rod body 25 is slidably connected to the pick-and-place bracket 21. The lower end of the rod body 25 is fixedly connected to the pick-and-place block 23. Exemplarily, the first elastic device 26 is a spring. The first elastic device 26 is sleeved on the rod body 25 in the upper and lower directions. The upper end of the first elastic device 26 contacts the pick-and-place bracket 21, and the lower end of the first elastic device 26 contacts the pick-and-place block 23. The first elastic device 26 pushes the pick-and-place block 23 downward.
[0048] When the pick-up block 23 moves downward, the pick-up block 23 and the pick-up rod 22 clamp the needle roller in the space 24. When the pick-up block 23 moves upward, the pick-up block 23 opens the space 24, and the needle roller falls from the space 24. Thus, the needle roller can be quickly clamped and quickly dropped, and the assembly efficiency of the needle roller is improved.
[0049] When the push column 5 pushes into the clamping end of the pick-and-place device 2, the push column 5 presses against the pick-and-place block 23 and pushes the pick-and-place block 23 to move upward, the first elastic device 26 is squeezed, the pick-and-place block 23 opens the space 24, and the roller needle falls from the space 24 into the feed box 4.
[0050] When the pick-and-place device 2 moves upward, the top column 5 moves away from the pick-and-place block 23, and the first elastic device 26 extends to push the pick-and-place block 23 to return to its original position.
[0051] The guide mechanism 7 includes: a guide bracket 71, a guide plate 72 arranged on the guide bracket 71, and a guide hole 73 opened in the middle of the guide plate 72. The guide plate 72 is horizontally arranged at the upper end of the guide bracket 71. The gear is located below the guide plate 72. The pick-and-place device 2 is close to the guide mechanism 7, the guide plate 72 is attached to and restricts the pick-and-place block 23, the pick-and-place rod 22 and the needle roller move downward through the guide hole 73, and the needle roller falls into the gear.
[0052] The pick-up and placement rod 22 and the needle roller pass through the guide hole 73, which guides the pick-up and placement rod 22 and the needle roller, thereby improving the position accuracy of the pick-up and placement rod 22 and the needle roller, so that the needle roller can accurately fall into the gear.
[0053] When the pick-and-place device 2 moves upward, the pick-and-place rod 22 moves out of the guide hole 73 , the pick-and-place block 23 moves away from the guide plate 72 , and the pick-and-place block 23 moves to reset.
[0054] The needle roller assembly detection mechanism also includes: a pushing mechanism 84, a placement bracket 83, a vibration plate 8 for conveying needle rollers, a placement bar 81 for arranging needle rollers, and a placement block 82 for placing needle rollers.
[0055] Among them, the placement block 82 is rotatably set on the placement bracket 83. The upper end of the placement bar 81 is close to the outlet of the vibration disk 8, and the lower end of the placement bar 81 is arranged with roller needles. The upper end of the placement bar 81 and the lower end of the placement bar 81 are connected to each other. An annular space is formed at the lower end of the placement bar 81, and the roller needles are arranged in the annular space. The roller needle moves out from the outlet of the vibration disk 8 to the upper end of the placement bar 81, and the roller needle falls along the placement bar 81 to the annular space, and a certain number of roller needles are arranged in the annular space. The pushing mechanism 84 pushes the roller needle from the placement bar 81 into the placement block 82, and the placement block 82 rotates a certain angle, and the placement block 82 faces upward, which is convenient for the placement device 2 to take the roller needle.
[0056] The placement block 82 includes a first block 821, a second block 822 movably arranged on the first block 821, and a rotating block 824 rotatably arranged on the second block 822. A second elastic device 823 is arranged on the first block 821. The second elastic device 823 elastically supports the second block 822. Exemplarily, the second elastic device 823 is a spring. One end of the second elastic device 823 is connected to the first block 821, and the other end of the second elastic device 823 is connected to the second block 822. The rotating block 824 accommodates a needle roller.
[0057] The first block 821 and the second block 822 are elastically connected by the second elastic device 823. When the second block 822 is close to the placement bar 81, hard contact between the rotating block 824 and the placement bar 81 is avoided, thereby avoiding damage to the roller needle.
[0058] The first power device 231 is installed on the placement bracket 83. For example, the first power device 231 is a cylinder. The first power device 231 drives the placement block 82 to move horizontally.
[0059] The second power device 232 is installed at the driving end of the first power device 231. Exemplarily, the second power device 232 is a rotary cylinder. The driving end of the second power device 232 is connected to the first block 821. The second power device 232 drives the placement block 82 to rotate, so that the rotating block 824 is close to the annular space of the placement bar 81 or toward the pick-and-place device 2.
[0060] The first block 821 is provided with a third power device 233, and a driving end of the third power device 233 is connected to a rotating block 824. The rotating block 824 can be driven to rotate by the third power device 233, and the rotating block 824 can accommodate a needle roller.
[0061] The driving end of the first power device 231 extends out, pushing the placement block 82 close to the annular space of the placement bar 81, and the annular space of the placement bar 81 is connected to the rotating block 824. The pushing mechanism 84 pushes into the annular space of the placement bar 81, pushing the needle roller in the annular space of the placement bar 81 into the rotating block 824. During the pushing process, the third power device 233 drives the rotating block 824 to rotate a certain angle, so that the needle roller is completely pushed into the position in the rotating block 824.
[0062] The driving end of the first power device 231 shrinks and resets, driving the placement block 82 away from the annular space of the placement bar 81, and the second power device 232 drives the placement block 82 to rotate a certain angle. The rotating block 824 faces upward, making it convenient for the pick-and-place device 2 to take the roller needle.
[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
