[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See Figures 1 to 5 A double-sided adhesive production line for structural parts includes a base, a turntable 1 is rotatably provided on the base, a plurality of fixtures 11 are fixedly connected to the top wall of the turntable 1, and a front-side positioning structure 111 and a back-side positioning structure 112 are provided on the top wall of the fixture 11.

[0032] The base is provided with a vibration plate 2, a feeding unit 3, a front gluing unit 4, a structural component flipping unit 5, and a back gluing unit 6 in sequence along the circumference of the turntable 1. The front gluing unit 4 is provided with a front gluing three-axis mechanical arm 41, which is provided with a front gluing nozzle 411 and a front gluing structural component positioning camera 412. A front gluing positioning camera 42 is provided on the front side of the front gluing three-axis mechanical arm 41.

[0034] The structural component flipping unit 5 is provided with a base, the base is slidably provided with a transverse slide 51, the transverse slide 51 is slidably provided with a vertical slide 52, the vertical slide 52 is provided with a flipping motor 53, and the rotating shaft of the flipping motor 53 is provided with a clamping mechanism.

[0035] Specifically, see Figure 2 A conveying trough 21 is fixedly connected to the discharge position of the vibration plate 2, a transverse cylinder 22 is fixedly connected to the front end of the conveying trough 21, a piston rod of the transverse cylinder 22 is connected to a discharge slider 221, and the discharge slider 221 is provided with a discharge notch 2211.

[0036] Specifically, the feeding unit 3 is provided with a longitudinal cylinder 31 , the piston rod of the longitudinal cylinder 31 is connected to a longitudinal slide 32 , the longitudinal slide 32 is fixedly connected to a vertical cylinder 33 , the piston rod of the vertical cylinder 33 is fixedly connected to a vertical slide 35 , and the vertical slide 35 is provided with a feeding nozzle 34 .

[0037] Specifically, see Figure 3 , Figure 5The front adhesive unit 4 is provided with a front adhesive feeding reel 43, a front adhesive receiving reel 44 and a front adhesive stripping slide 45. The front adhesive stripping slide 45 includes a front adhesive stripping plate 451. The front adhesive stripping plate 451 has a folding slope at the bottom of the front edge. The folding slope gradually tilts downward from the front to the back. The front adhesive tape segment 431 fed by the front adhesive feeding reel 43 passes around the front edge of the front adhesive stripping plate 451 and is then rolled into the front adhesive receiving reel 44 for recycling.

[0038] Specifically, see Figure 1 , Figure 3 The back adhesive unit 6 is provided with a back adhesive feeding reel 63, a back adhesive receiving reel (not shown in the figure) and a back adhesive stripping slide 65. The back adhesive stripping slide 65 includes a back adhesive stripping plate 651. A folding slope is provided at the bottom side of the front edge of the back adhesive stripping plate 651, and the folding slope gradually tilts downward from the front to the back. After the back adhesive tape section fed by the back adhesive feeding reel 63 passes around the front edge of the back adhesive stripping plate 651, it is rolled into the back adhesive receiving reel for recovery.

[0039] Specifically, see Figure 2 The front side positioning structure 111 and the back side positioning structure 112 both have six positioning columns, and the six positioning columns are distributed along a rectangle.

[0040] Specifically, see Figure 4 The clamp mechanism includes a double-piston cylinder 54, and the two pistons of the double-piston cylinder 54 are fixedly connected to a clamp arm 541. The inner side of the front section of the clamp arm 541 is provided with a gap to avoid air.

[0041] Specifically, a three-axis unloading robot arm 71 and a unloading conveyor belt 72 are provided at a circumferential position below the back-side adhesive laminating unit 6 , and the three-axis unloading robot arm 71 is provided with a unloading suction nozzle 711 .

[0042] The working principle of the double-sided adhesive production line for structural parts of the utility model is as follows:

[0043] See Figure 2 The vibrating plate 2 delivers the structural parts along the conveying trough 21. Under normal conditions, the side wall of the discharge slide block 221 blocks the discharge of the conveying trough 21 (e.g. Figure 2 The discharge slider 221 slides back and forth in the horizontal direction. Whenever the discharge notch 2211 moves with the discharge slider 221 to align with the discharge port of the conveying trough 21, the conveying trough 21 discharges a structural member into the discharge notch 2211. Then, the discharge slider 221 moves horizontally and resets to Figure 2 Status shown.

[0044] The loading unit 3 controls the loading nozzle 34 to move to the upper side of the discharge notch 2211 and absorbs the structural parts in the discharge notch 2211. Then, the loading unit 3 controls the loading nozzle 34 to move to the front positioning structure 111 of the fixture 11. Subsequently, the fixture 11 rotates with the turntable 1 to the front end of the front adhesive unit 4. The front adhesive three-axis robot 41 drives the front adhesive nozzle 411 to move to the front edge of the front adhesive stripping plate 451. The front edge is the position where the front adhesive and the bottom tape of the front adhesive tape segment 431 are peeled off from each other. For the specific peeling principle, please refer to Chinese Patent 2024203595272. After the front adhesive nozzle 411 absorbs the peeled front adhesive at the front edge of the front adhesive stripping plate 451, it moves to the upper side of the front adhesive positioning camera 42, thereby adjusting the angle position of the front adhesive nozzle 411, so as to position the front adhesive. Then, the front adhesive three-axis robot arm 41 drives the front adhesive structural component positioning camera 412 to move forward to align with the adhesive front positioning structure 111 to position the structural component in the adhesive front positioning structure 111. After completing the positioning of the structural component, the front adhesive three-axis robot arm 41 drives the front adhesive suction nozzle 411 to move to the upper side of the structural component and sticks the front adhesive to the surface of the structural component.

[0045] Then, the turntable 1 drives the jig 11 to move to the front side of the structural component flipping unit 5, and then, the two clamping arms 541 move down to the two sides of the structural component (the front adhesive has been pasted) in the front positioning structure 111, and then the two clamping arms 541 move together to clamp the structural component. Then, the two clamping arms 541 move up together with the structural component, and then, the two clamping arms 541 and the structural component rotate 180° around the rotation axis of the flipping motor 53 to achieve the flipping of the structural component so that the back of the structural component faces upward. Then, the two clamping arms 541 and the structural component move horizontally to align with the back positioning structure 112, and then, the two clamping arms 541 move down, so as to place the flipped structural component on the back positioning structure 112.

[0046] Then, the turntable 1 drives the jig 11 to move to the back side gluing unit 6, which is used to glue the back side of the structural member. This process is similar to the process of gluing the front side of the structural member by the front side gluing unit 4, and can be referred to above, which will not be repeated here.

[0047] After the adhesive is applied to the back of the structural part, the turntable 1 drives the jig 11 to move to the unloading three-axis robot arm 71. The unloading suction nozzle 711 of the unloading three-axis robot arm 71 absorbs the structural part with adhesive applied to the back and moves it to the unloading conveyor belt 72 to realize unloading.

[0048] The front adhesive unit 4 of the utility model can automatically apply the front adhesive to the structural parts. In the process, the front adhesive positioning camera 42 is used to position the front adhesive, and the front adhesive structural part positioning camera 412 is used to position the structural parts. Both the front adhesive positioning camera 42 and the front adhesive structural part positioning camera 412 are CCD cameras with high positioning accuracy, ensuring the accurate adhesive pasting position and preventing missed pasting. Pasting adhesive by a three-axis robot arm can greatly improve work efficiency and reduce labor. Similarly, the back adhesive unit 6 also plays a role in improving work efficiency and reducing labor.

[0049] A structural part flipping unit 5 is provided between the front glue sticking unit 4 and the back glue sticking unit 6. The structural part flipping unit 5 can flip the structure efficiently and conveniently, so that the front glue sticking and the back glue sticking links are seamlessly connected, thereby further improving the glue sticking efficiency.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
