Description

Scroll spring orthotic devices and scroll spring assembly equipment

Technical Field

The invention relates to the technical field of machining equipment, in particular to a volute spring correcting device and spring assembling equipment provided with the volute spring correcting device.

Background

The feeding device of the conventional scroll spring assembly equipment generally comprises a vibration disc and a direct vibration unit, wherein the vibration disc orients, selects and sorts the scroll springs through a spiral track in the vibration disc and then transfers the spiral springs to the direct vibration unit so as to transfer the scroll springs to a later-stage device of the feeding device one by one under the assistance of the direct vibration unit for subsequent processing. However, the existing feeding devices have the following disadvantages:

The current vibration disk can generally only control the scroll spring to enable the winding end of the scroll spring to be positioned in front of the winding main body or enable the winding end of the scroll spring to be positioned behind the winding main body when the scroll spring moves out of the spiral track when the scroll spring is oriented and/or oriented; and the spiral direction of all the spiral springs can not be kept the same when the spiral springs are moved out of the spiral track, namely the front side and the back side of the spiral springs can not be screened. For example, assuming that the vibration plate requires the winding end of the coil spring to be located behind the winding body when the coil spring is fed out of the spiral track, as shown in fig. 1, the winding end 912 of the coil spring 91 is controlled to be located behind the winding body 911 when the coil spring 91 is moved out of the spiral track 93; the coil end 922 of the scroll spring 92 is also controlled to be located rearward of the coil body 921 as the scroll spring 92 moves out of the spiral track 93. However, in this case, the spiral direction of the scroll spring 91 is opposite to that of the spiral spring 92, that is, the spiral spring 92 is disposed in the opposite direction assuming that the spiral spring 91 is disposed in the opposite direction.

Therefore, in the assembling process of the scroll spring, if the assembling position of the scroll spring does not have the front and back assembling requirements, the scroll spring sent out after being screened by the vibration disc can meet the assembling requirements; however, if the assembly position of the scroll spring has the front and back assembly requirements in the assembly process, the scroll spring sent out after the vibration disc is screened still cannot meet the assembly requirements, that is, the conventional scroll spring assembly equipment cannot assemble the scroll spring with the front and back assembly requirements, and has larger use limitation.

The third sensing piece 715 can synchronously rotate along with the second driving component 713, so that the third notch can move into a fifth through slot of the fifth slot type photoelectric switch or move into a sixth through slot of the sixth slot type photoelectric switch. Through the arrangement, the third sensing piece 715 can be matched with the fifth position detection sensor 716 to perform an origin searching function on the two second clamping jaws 711, so that the rotation angle of the grabbing mechanism 71 on the volute spring 101 is ensured; the third sensing piece 715 can also have a limiting effect on the rotation angle of the two second clamping jaws 711 by the sixth position detecting sensor 717, so as to prevent the two second clamping jaws 711 from clamping the volute spring 101 to excessively rotate.

The seventh driving mechanism 72 includes a fourth driving assembly 721714 and a fifth driving assembly 722, wherein the fourth driving assembly 721714 includes a fifth linear cylinder 7211, a first rail 7212 and a fourth slide table 7213, the fifth linear cylinder 7211 and the first rail 7212 are fixedly mounted on the frame 10, and a fifth piston rod of the fifth linear cylinder 7211 and the first rail 7212 are parallel to the third direction Y.

It can be seen that by the structural design of the transplanting unit 7, the seventh drive mechanism 72 is enabled to drive the gripping mechanism 71 to move to the gripping end 41 of the tilting unit 4.

Referring to fig. 10 and 11, the support unit 8 is mounted on the frame 10, the support unit 8 includes a support seat 81 and an eighth driving mechanism 82, the support seat 81 has a support portion 811, when the driving unit 5 drives the turning unit 4 to move to the support unit 8, the support portion 811 can support the scroll spring 101 clamped by the turning unit 4, and further, when the seventh driving mechanism 72 of the transplanting unit 7 drives the grabbing mechanism 71 to move to the support portion 811 to clamp the scroll spring 101, the scroll spring 101 does not fall from the clamping end of the turning unit 4, and the reliability of clamping the scroll spring 101 by the grabbing mechanism 71 is ensured. The eighth driving mechanism 82 preferably employs a seventh linear cylinder, a seventh piston rod of the seventh linear cylinder being parallel to the third direction Y, and the support base 81 is fixedly connected to the seventh piston rod, so that the eighth driving mechanism 82 can drive the support base 81 to move to the clamping end 41 of the flipping unit 4 in the third direction Y.

The operation of the scroll spring orthotic 100 is briefly described below with reference to fig. 1-11:

it is assumed that, in the initial state, the sixth driving mechanism 27 of the locating unit 2 drives the material taking seat 21 to move to the outlet of the material receiving groove 111 of the material receiving seat 11, and the first driving mechanism 22 drives the opening of the accommodating position 211 of the material taking seat 21 to be disposed towards the outlet of the material receiving groove 111.

Next, the feeding device interfacing with the scroll spring straightening device 100 transfers the selected scroll spring 101 into the receiving groove 111 of the receiving seat 11 of the distributing unit 1, and moves the scroll spring 101 into the receiving position 211 of the material taking seat 21 via the receiving groove 111. When the first scroll spring 101 moves to the accommodating position 211 of the material taking seat 21, the third position detection sensor 12 detects that the scroll spring 101 is on the material taking seat 21 at the moment, and then sends a third detection signal to the control system, so that the control system controls the first driving component 132 of the material distributing mechanism 13 to drive the second pressing block 131 to move towards the material receiving groove 111, and the second pressing block 131 is used for fixing the second scroll spring 101 in the material receiving groove 111 on the material receiving seat 11, so that the second scroll spring 101 and the following scroll springs 101 are prevented from moving towards the outlet of the material receiving groove 111.

Then, the fifth driving mechanism 25 of the locating unit 2 controls the limiting part 241 of the limiting rod 24 to extend into the accommodating position 211, so that the limiting part 241 is inserted into the empty space in the middle of the volute spring 101; subsequently, the sixth driving mechanism 27 drives the material receiving seat 11 to move to the first position detection sensor 23; subsequently, the first driving mechanism 22 drives the receiving seat 11 to rotate, so that the receiving seat 11 drives the volute spring 101 thereon to rotate to search for the position of the winding end of the volute spring 101, and when the winding end of the volute spring 101 moves to the detection end of the first position detection sensor 23, the first position detection sensor 23 sends a first detection signal to the control system, so that the control system controls the first driving mechanism 22 to stop driving the material taking seat 21.

Then, the fourth driving mechanism 62 of the compressing unit 6 drives the first pressing block 61 to move toward the scroll spring 101 on the material taking seat 21 to compress the scroll spring 101 on the material taking seat 21; subsequently, the second driving mechanism 32 of the detecting unit 3 drives the detecting end 31 to move toward the scroll spring 101 on the material taking seat 21, and if the placement position of the scroll spring 101 at this time is opposite to the placement position of the scroll spring 101 (as shown in fig. 10), the insert plate 311 of the detecting end 31 is inserted into the gap, so that the first sensing piece 312 on the detecting end 31 moves into the second through slot of the second position detecting sensor 33 at this time, and the second position detecting sensor 33 sends a second detecting signal to the control system to control the turning unit 4 to execute the turning operation subsequently.

Next, the driving unit 5 drives the flipping unit 4 to move to the detection end of the first position detection sensor 23; subsequently, the third driving mechanism 42 of the flipping unit 4 drives the holding end 41 to hold the wrap end of the scroll spring 101.

Then, the fourth driving mechanism 62 of the pressing unit 6 drives the first pressing block 61 to reset to release the pressing fixation of the scroll spring 101, and at the same time, the second driving mechanism 32 of the detecting unit 3 drives the detecting tip 31 to reset.

Then, the driving unit 5 drives the turning unit 4 to move to the supporting unit 8, and at the same time, the turning unit 4 clamps the scroll spring 101 to rotate 180 degrees around the second rotation axis so as to adjust the placement position state of the scroll spring 101 from the back placement to the front placement; while the driving unit 5 drives the turning unit 4 to move toward the supporting unit 8, the eighth driving mechanism 82 of the supporting unit 8 drives the supporting seat 81 to move toward the turning unit 4 along the third direction Y, and when the driving unit 5 drives the turning unit 4 to move to the supporting unit 8, the volute spring 101 clamped by the turning unit 4 is just placed on the supporting portion 811 of the supporting seat 81. Meanwhile, the sixth driving mechanism 27 of the driving unit 5 may drive the material taking seat 21 to move to the material receiving seat 11, and the first driving mechanism 22 may drive the opening of the accommodating position 211 of the material taking seat 21 to be disposed towards the outlet of the material receiving groove 111 again in preparation for receiving the second volute spring 101, wherein when the material taking seat 21 is located at the material receiving seat 11 and the opening of the accommodating position 211 is located towards the outlet of the material receiving groove 111, the first driving component 132 of the material distributing mechanism 13 drives the second pressing block 131 to move upwards so as to move the second volute spring 101 towards the material taking seat 21. It should be noted that, if the state of the placement position of the scroll spring 101 on the material taking seat 21 is that the scroll spring 101 is placed in the front, when the second driving mechanism 32 of the detecting unit 3 drives the detecting end 31 to move toward the scroll spring 101, the insert plate 311 of the detecting end 31 will abut against the winding end or the winding body of the scroll spring 101, so that the first sensing piece 312 of the detecting end 31 cannot move into the second notch of the second position detecting sensor 33, and at this time, the control system determines that the placement position of the scroll spring 101 on the material taking seat 21 is correct, and the overturning unit 4 does not need to adjust the placement position of the scroll spring 101 in the process of clamping the scroll spring 101 to the supporting unit 8.

After the driving unit 5 controls the flipping unit 4 to clamp the scroll spring 101 onto the supporting portion 811, the seventh driving mechanism 72 of the transplanting unit 7 drives the grasping mechanism 71 to move toward the supporting portion 811 to clamp the scroll spring 101 clamped by the flipping unit 4. When the grasping mechanism 71 grasps the scroll spring 101, the flipping unit 4 releases the grasping of the scroll spring 101.

Then, the seventh driving mechanism 72 of the transplanting unit 7 drives the grabbing mechanism 71 to draw the volute spring 101 to move towards the subsequent device or related parts of the volute spring rectifying device 100, and in the moving process, the third driving assembly 713 of the grabbing unit rotates the volute spring 101 by a preset angle according to design requirements; at the same time, the support unit 8 and the flipping unit 4 are reset, ready to process the second volute spring 101.

In summary, when the assembly of the scroll spring has the front and back assembly requirements, the scroll spring correcting device can adjust the placement position of the scroll spring according to the detection result of the detection unit, so that the scroll spring can meet the assembly requirements of subsequent assembly processing.
