[0056] Embodiment 1

[0057] like Figure 1-Figure 5 As shown, an automatic assembly device for outdoor rattan chair accessories includes:

[0058] An assembly mechanism 1, the assembly mechanism 1 comprises a first installation assembly 11 and a second installation assembly 12, the first installation assembly 11 completes the assembly work of the connection bracket 300 and the plurality of connection legs 200 delivered to the assembly station, and the second installation assembly 12 completes the assembly work of the connection bracket 300 and the support legs 100 delivered to the assembly station;

[0059] A first mounting assembly 11, the first mounting assembly 11 comprises a first punching member 111 disposed at the upper end of the connecting bracket 300 and a first tightening member 112 disposed at the lower end of the connecting bracket 300 and synchronously driven with the first punching member 111, when the first punching member 111 moves downward in the vertical direction to complete the processing of the threaded holes on the connecting bracket 300 and the connecting leg 200 and moves upward, the first tightening member 112 drives the first bolt to rotate upward and complete the assembly of the connecting bracket 300 and the connecting leg 200;

[0060] The second mounting component 12 includes a second punching member 121 and a second tightening member 122 arranged on the outside of the connecting bracket 300. After the second punching member 121 moves toward the connecting bracket 300 in the horizontal direction to complete the processing of the threaded hole in the middle of the connecting bracket 300, under the guidance of the guide member 123, the second punching member 121 moves upward and avoids the second tightening member 122. At the same time, the second tightening member 122 drives the second bolt to rotate toward the connecting bracket 300 and completes the assembly of the connecting bracket 300 and the support leg 100.

[0061] In this embodiment, the first installation component 11 is provided to cooperate with the second installation component 12 to respectively complete the assembly work between the connecting bracket 300 and the connecting leg 200 and between the connecting bracket 300 and the supporting leg 100 .

[0062] Further, if Figure 2 As shown, the assembly mechanism 1 further includes an upper support plate 13 and a lower support plate 14 for supporting the first mounting assembly 11 and the second mounting assembly 12 , and the upper end of the upper support plate 13 is connected to the assembly frame 16 via a first driving unit 15 .

[0063] In this embodiment, by setting an upper support plate 13 and a lower support plate 14, the upper support plate 13 and the lower support plate 14 can provide good support for the first installation component 11 and the second installation component 12, and the first drive unit 15 and the upper support plate 13 can simultaneously drive the first installation component 11 and the second installation component 12 to move downward to the assembly station.

[0064] In detail, the lower support plate is fixedly arranged on the assembly frame 16, and the upper support plate 13 is connected to the assembly frame 16 through the first driving unit 15. The first driving unit 15 can be a cylinder. After the first driving unit 15 is working, it can drive the upper support plate 13 to move downward and drive the first mounting component 11 and the second mounting component 12 to move downward, thereby facilitating the first mounting component 11 and the second mounting component 12 to complete the assembly work respectively.

[0065] It should be noted that, in order to ensure the stability of the upper support plate 13 , a plurality of elastic expansion units are further provided between the upper support plate 13 and the assembly frame 16 .

[0066] Further, if Figure 3-Figure 4 As shown, the first punching member 111 is provided with two groups and includes a first drilling machine 1111 fixed to the lower end of the upper support plate 13;

[0067] The first tightening member 112 includes a rotating rod 1121 rotatably disposed on the lower support plate 14 and a second driving unit 1122 fixedly disposed on the upper end of the rotating rod 1121;

[0068] The second punching member 121 includes a third driving unit 1212 connected to the upper support plate 13 via a first elastic expansion unit 1211 and a second drilling machine 1213 connected to the third driving unit 1212;

[0069] The second tightening member 122 includes a bolt tightening machine 1221 fixed to the lower end of the upper support plate 13 .

[0070] In this embodiment, by setting a first punching member 111 in cooperation with the first tightening member 112, the simultaneous processing of the threaded holes on the connecting leg 200 and the connecting bracket 300 and the assembly of the bolts are achieved. By setting a second punching member 121 in cooperation with the second tightening member 122, the simultaneous processing of the threaded holes on the supporting leg 100 and the connecting bracket 300 and the assembly of the bolts are achieved.

[0071] In detail, after the first driving unit 15 works, it drives the upper support plate 13 to move downward, and drives the first drilling machine 1111 to move downward. At the same time, the first drilling machine 1111 works to complete the processing of the threaded holes on the connecting leg 200 and the connecting bracket 300. After completing the processing of the threaded holes, the first driving unit 15 and the first drilling machine 1111 stop working, and then the third driving unit 1212 and the second drilling machine 1213 work at the same time. The third driving unit 1212 drives the second drilling machine 1213 to move toward the connecting bracket 300 and complete the processing of the threaded holes on the connecting bracket 300 and the supporting leg 100. After the processing is completed, the second drilling machine 1213 stops working, and the third driving unit 1212 works in the reverse direction and drives the second drilling machine 1213 away from the connecting bracket 300. At the same time, the third driving unit 121 2 and the second drilling rig 1213 will rise and avoid the second tightening member 122, and the end of the second tightening member 122 close to the connecting bracket 300 will drive the second bolt toward the connecting bracket 300 and fix the second bolt between the connecting bracket 300 and the supporting leg 100. After completing the fixing work, the second tightening member 122 retreats backwards, at this time, the first driving unit 15 drives the upper support plate 13 to move upward and drives the rotating rod 1121 to rotate on the lower support plate 14, and at the same time, the second driving unit 1122 works and drives the first bolt at its upper end to move upward to the threaded holes on the connecting leg 200 and the connecting bracket 300 and complete the assembly work. After completing the assembly, the second driving unit 1122 retreats, so far, the assembly work between the connecting bracket 300 and the connecting leg 200, and the connecting bracket 300 and the supporting leg 100 is completed.

[0072] It should be noted that the second driving unit 1122 and the third driving unit 1212 may be cylinders, and the first bolt and the second bolt may be placed manually or automatically.

[0073] Further, if Figure 4As shown, the first installation component 11 also includes:

[0074] The transmission member 113 includes a mounting rack 1131 fixedly arranged on the outside of the first drilling rig 1111, a mounting gear 1132 matched with the mounting rack 1131 and arranged on the lower support plate 14, a first transmission bevel gear 1133 coaxially arranged with the mounting gear 1132, and a second transmission bevel gear 1134 matched with the first transmission bevel gear 1133 and fixedly arranged on the outside of the rotating rod 1121.

[0075] In this embodiment, the transmission member 113 is provided to cooperate with the first tightening member 112 to complete the rotation of the rotating rod 1121.

[0076] In detail, when the mounting rack 1131 on the outside of the first drilling rig 1111 moves upward driven by the first driving unit 15, it drives the mounting gear 1132 to rotate, and the mounting gear 1132 drives the second transmission bevel gear 1134 to rotate through the first transmission bevel gear 1133 and drives the rotating rod 1121 to rotate.

[0077] It should be noted that in order to ensure that the first bolt can be installed, it is necessary to ensure that the number of rotations of the installation gear 1132 is not less than the number of rotations of the thread on the first bolt. Therefore, it is necessary to ensure that the installation gear 1132 is smaller. In this way, the installation gear 1132 can complete a larger number of rotations driven by the installation rack 1131.

[0078] Further, if Figure 5-Figure 7 As shown, the guide member 123 includes a guide rod 1231 fixedly connected to the second drilling rig 1213 and a guide plate 1232 matched with the guide rod 1231;

[0079] A vertical slide groove 1233, a horizontal slide groove 1234 and an inclined slide groove 1235 are provided inside the guide plate 1232 to match the guide rod 1231. A convex plate 1236 is fixedly provided inside the horizontal slide groove 1234. An arc-shaped end 12361 is provided at one end of the convex plate 1236 close to the vertical slide groove 1233. An inclined end 12362 is provided at one end of the convex plate 1236 close to the inclined slide groove 1235.

[0080] The guide plate 1232 is provided with a notch 1237 at a position corresponding to the vertical slide groove 1233 , a bending plate 1238 is rotatably provided inside the notch 1237 , and a straight rod 1239 is fixedly provided at the lower end of the upper support plate 13 at a position corresponding to the bending plate 1238 .

[0081] In this embodiment, by setting a guide member 123 to cooperate with the second drilling rig 1213, when the second drilling rig 1213 completes the drilling work and returns, the guide member 123 can drive the second drilling rig 1213 to move upward and avoid the second tightening member 122 set at its rear end.

[0082] In detail, when the second drilling rig 1213 moves toward the connecting bracket 300, the guide rod 1231 will slide inside the horizontal slide groove 1234. After the drilling work is completed, the guide rod 1231 moves to the end of the horizontal slide groove 1234. Then, when the second drilling rig 1213 drives the guide rod 1231 to retreat backward, the guide rod 1231 will move obliquely upward along the inclined slide groove 1235. At the same time, the second drilling rig 1213 will move upward synchronously driven by the first elastic telescopic unit 1211. Because the first driving unit 15 drives the upper support plate 13 to move downward, it will drive the straight rod 1239 to move downward synchronously. Therefore, one end of the bending plate 1238 will be driven to flip to the inside of the vertical slide groove 1233. When the second drilling rig 1213 drives the guide rod 1231 to move to the position of the vertical slide groove 1233, under the action of gravity, the guide rod 1231 will drop to the upper end of the bending plate 1238. At this time, the second drilling rig 1213 hovers at this position and no longer moves downward until the second tightening member 122 completes the tightening work, the first driving unit 15 drives the upper support plate 13 to move upward, and the straight rod 1239 no longer limits the bending plate 1238. Then, the guide rod 1231 can continue to slide on the vertical slide groove 1233.

[0083] It should be noted that a torsion spring is arranged between the bending plate 1238 and the guide plate 1232. When the straight rod 1239 is not in contact with the bending plate 1238, the bending plate 1238 will not flip to the inside of the vertical slide groove 1233, and the rear end of the guide plate 1232 is fixed to the assembly frame 16 through a plurality of support rods 12321 with elastic units. In this way, when the guide rod 1231 passes through the arc end 12361 or the inclined end 12362, the guide plate 1232 will move away from or approach the guide rod 1231.

[0084] Further, if Figure 8-Figure 9 As shown, it also includes a connecting leg feeding mechanism 2, and the connecting leg feeding mechanism 2 has multiple groups of limit assemblies 22, clamping assemblies 23 and supporting assemblies 24 in sequence along the transmission direction of the first conveying assembly 21;

[0085] A limiting assembly 22, the limiting assembly 22 comprising a limiting bracket 221 disposed on the first conveying assembly 21 and a limiting plate 222 connected to the limiting bracket 221 via a limiting spring;

[0086] The clamping assembly 23 comprises a clamping bracket 231 arranged on the first transmission assembly 21, a threaded rod 232 arranged on the clamping bracket 231 and having two sets of threaded portions with opposite rotation directions at its upper end, clamping blocks 233 respectively arranged on the threaded portions, and a clamping gear 234 arranged on the outer side of the threaded rod 232, the first transmission assembly 21 is respectively provided with a first clamping rack 235 and a second clamping rack 236 at positions corresponding to the clamping gear 234, the first clamping rack 235 and the second clamping rack 236 respectively drive the clamping gear 234 to rotate in opposite directions;

[0087] The supporting assembly 24 includes a supporting bracket 241 fixedly disposed on the first conveying assembly 21 .

[0088] In this embodiment, by setting up a first conveying component 21 in conjunction with multiple groups of limit components 22, clamping components 23 and support components 24, the clamping and feeding of multiple connecting legs 200 can be completed. At the same time, the connecting leg feeding mechanism 2 can be provided with two groups for feeding connecting legs 200 at two different positions.

[0089] In detail, when placing the connecting leg 200, one end of the connecting leg 200 needs to be set close to the limit plate 222 in the limit assembly 22, and the middle part can be placed on the clamping bracket 231 and the support bracket 241. When the first transmission assembly 21 is working, the clamping gear 234 in the clamping assembly 23 will contact the first clamping rack 235 and rotate. After the clamping gear 234 rotates, it will drive the threaded rod 232 to rotate and drive the two clamping blocks 233 to approach each other to complete the clamping of the connecting leg 200. After the assembly mechanism 1 completes the assembly work, the clamping gear 234 in the clamping assembly 23 will contact the second clamping rack 236 and drive the clamping gear 234 to rotate in the opposite direction so that the connecting leg 200 will no longer be clamped. As the first transmission assembly 21 continues to move, the end of the connecting leg 200 close to the limit plate 222 will squeeze and drive the limit plate 222 to rotate until the limit assembly 22 no longer contacts the connecting leg 200.

[0090] It should be noted that since both the supporting leg 100 and the connecting leg 200 are round tubes, in order to make the contact between the two round tubes closer, after the clamping assembly 23 completes the clamping work of the connecting leg 200 and before the assembly mechanism 1 performs the assembly work, a punching machine is used to punch the end of the connecting leg 200 away from the limiting plate 222 to form an arc shape, so that the connecting leg 200 can fit tightly with the supporting leg 100, and the first transmission assembly 21 is a belt conveyor device.

[0091] Further, if Fig.10As shown, it also includes a connecting bracket loading mechanism 3, which includes a fixing block 32 fixedly arranged on the second conveying assembly 31 and a plurality of limiting blocks 33 arranged on the outside of the fixing block 32 through buffer springs.

[0092] In this embodiment, the feeding work of the connecting bracket 300 can be completed by setting the second conveying component 31 in cooperation with the fixing block 32 .

[0093] In detail, the connecting bracket 300 is in the shape of a rectangular block. In order to make the connecting bracket 300 and the connecting leg 200 fit tightly together, it is necessary to punch out arc grooves matching the connecting legs 200 on both ends of the connecting bracket 300 in advance. Therefore, there is no need to clamp the connecting bracket 300 when placing the connecting bracket 300. It is only necessary to place the connecting bracket 300 between multiple limit blocks 33 and set the arc groove toward the connecting leg 200. Driven by the second transmission component 31, one of the arc grooves of the connecting bracket 300 will first contact one of the connecting legs 200 on both sides, and then the connecting bracket 300 will slide on the fixed block 32 until the two arc grooves are respectively matched with the connecting legs 200. After the assembly mechanism 1 completes the assembly work, as the second transmission component 31 continues to move, the connecting bracket 300 will squeeze and drive the limit block 33 at the rear end to rotate until the fixed block 32 no longer contacts the connecting bracket 300.

[0094] Further, if Fig.11 As shown, a first intermittent drive mechanism 4 is arranged on the outer side of the connecting leg feeding mechanism 2, and the first intermittent drive mechanism 4 includes a fourth drive unit 41 fixedly arranged on the lower support plate 14 and controlling the operation of the first conveying component 21, a first bevel gear 42 connected to the fourth drive unit 41 and arranged on the outer side of the first conveying component 21, and a transmission unit 43 which is arranged in transmission with the first bevel gear 42 and arranged on the outer side of the second conveying component 31.

[0095] In this embodiment, by setting up a first intermittent driving mechanism 4 to cooperate with the connecting leg feeding mechanism 2 and the connecting bracket feeding mechanism 3, the synchronous feeding work of the connecting leg 200 and the connecting bracket 300 on the connecting leg feeding mechanism 2 and the connecting bracket feeding mechanism 3 can be achieved.

[0096] In detail, after the fourth driving unit 41 is working, it drives the first transmission component 21 to work through the output shaft, and drives the second bevel gear arranged on the outside of the transmission unit 43 to rotate through the first bevel gear 42. The second bevel gear drives the transmission unit 43 to work and drives the second transmission component 31 to work. At the same time, the second transmission component 31 drives the work of another first transmission component 21 through the above structure.

[0097] It should be noted that the fourth drive unit 41 can be an electric motor, the transmission unit 43 is a small belt transmission component, and the upper end of the first transmission component 21 close to the fourth drive unit 41 is fixedly provided with a sensing unit 211 at a position corresponding to the threaded rod 232. When the first transmission component 21 drives the clamping component 23 to move and the threaded rod 232 moves to the upper end of the sensing unit 211, the sensing unit 211 will send a signal to the controller and control the fourth drive unit 41 to stop working, so as to facilitate the start of the assembly mechanism 1. When the second drive unit 1122 completes the work and exits, that is, after the assembly mechanism 1 completes the work, the fourth drive unit 41 will restart to continue the subsequent processing work.

For the sake of simplicity, only the differences from the above embodiment are described below. The differences between this embodiment and the above embodiment are:

[0100] Further, if Fig.12 As shown, it also includes a second intermittent drive mechanism 5, which includes:

[0101] A driving assembly 51, wherein the driving assembly 51 includes a fifth driving unit 511 and a reduction unit 512;

[0102] An intermittent transmission assembly 52, the intermittent transmission assembly 52 comprising a driving bevel gear 521 connected to the reduction unit 512, a driven bevel gear 522 arranged in transmission with the driving bevel gear 521, an intermittent gear 523 arranged coaxially and fixedly connected with the driven bevel gear 522, and a transmission gear 524 arranged in transmission with the intermittent gear 523;

[0103] A bearing assembly 53, the bearing assembly 53 comprising a transmission rod 531 fixedly connected to the transmission gear 524, a plurality of bearing plates 532 arranged in an array along the axis direction of the transmission rod 531, and a clamping member 533 arranged on the bearing plate 532 for clamping the leg 100;

[0104] In this embodiment, by providing the second intermittent drive mechanism 5 , the legs 100 can be loaded to the assembly station one by one and the assembly mechanism can be cooperated to complete the assembly work of the legs 100 and the connecting legs 200 and the connecting bracket 300 .

[0105] In detail, the fifth driving unit 511 can drive the active bevel gear 521 to work through the reduction unit 512, and the active bevel gear 521 drives the intermittent gear 523 to rotate through the driven bevel gear 522. When some teeth on the intermittent gear 523 contact the transmission gear 524, the transmission rod 531 and the supporting plate 532 are driven to rotate, and the transfer and feeding of the support leg 100 are completed through the clamping member 533.

[0106] It should be noted that the clamping member 533 may be a clamping claw driven by a cylinder.

[0107] Further, if Figure 13-14 As shown, a leg feeding mechanism 6 is provided on one side of the second intermittent driving mechanism 5, which comprises:

[0108] A material storage assembly 61, the material storage assembly 61 comprising a material storage rack 611 for placing the supporting leg 100 and a material pusher plate 613 disposed on one side of the supporting leg 100 and connected to the material storage rack 611 via a second elastic telescopic unit 612;

[0109] The material shifting assembly 62 includes a cam 621 disposed at the upper end of the intermittent gear 523 and coaxially disposed with the intermittent gear 523, a limit clamping plate 623 provided with a protrusion 622 at a position corresponding to the cam 621 and one end of which is disposed at the lower end of the material storage rack 62, a chuck 625 matched with a claw 624 on the limit clamping plate 623, a material shifting plate 626 fixedly connected to the chuck 625, and a plurality of material shifting rods 627 fixedly disposed on the material shifting plate 626;

[0110] The middle portion of the limit clamping plate 623 is connected to the material storage rack 62 via a tension spring 628 .

[0111] In this embodiment, the outrigger loading mechanism 6 is provided in cooperation with the second intermittent driving mechanism 5 to realize automatic loading and transportation of the outrigger 100 .

[0112] In detail, after some teeth on the intermittent gear 523 are in contact with the transmission gear 524, the supporting plate 532 no longer rotates, and the cam 621 set on the intermittent gear 523 will limit the protrusion 622 on the card plate 623 and drive the limiting card plate 623 to rotate. When the claw 624 on the limiting card plate 623 is no longer in contact with the slot on the chuck 625, the second elastic telescopic unit 612 will push multiple legs 100 toward the supporting plate 532 at the same time through the pushing plate 613, and then the frontmost leg 100 will be clamped by the clamping member 533. As the cam 621 continues to rotate, the limiting card plate 623 will be reset under the drive of the tension spring 628, so that the claw 623 is in contact with the chuck 625 again, and the material dial 626 no longer rotates.

[0113] It should be noted that one end of the limiting clamping plate 623 away from the clamping claw 623 is rotatably arranged at the lower end of the storage rack 62 .

[0114] Working steps:

[0115] First, the operator places a plurality of legs 100 inside the storage rack 611, and starts the fifth driving unit 511 to drive the second intermittent driving mechanism 5 and the leg loading mechanism 6 to work. After some teeth on the intermittent gear 523 contact the transmission gear 524, the transmission rod 531 and the carrying plate 532 are driven to rotate, so that the legs 100 are moved to the assembly station.

[0116] Secondly, a plurality of connecting legs 200 and connecting brackets 300 are placed on the connecting leg loading mechanism 2 and the connecting bracket loading mechanism 3 respectively, and the fourth driving unit 41 is started to drive the first conveying assembly 21 and the second conveying assembly 31 to work, so that the connecting legs 200 and the connecting brackets 300 are moved to the assembly station;

[0117] Then, the fourth driving unit 41 stops working, and the first driving unit 15 works and drives the first installation assembly 11 and the second installation assembly 12 to respectively complete the assembly work between the connecting bracket 300 and the connecting leg 200, and between the connecting bracket 300 and the supporting leg 100;

[0118] Finally, the fourth drive unit 41 continues to work. When the limit assembly 22, the clamping assembly 23 and the support assembly 24 no longer support the connecting leg 200, and the fixed block 32 no longer supports the connecting bracket 300, some teeth on the intermittent gear 523 will re-contact the transmission gear 524 and drive the supporting plate 532 to continue to rotate. Subsequently, the clamping piece 533 that clamps the supporting leg 100 is released and the product after the assembly work is completed will be clamped away by another robot to complete the unloading work.
