The S3 lifting mechanism raises the positioning mechanism of the second tray to a set height, and the manual staff places the strips to be processed one by one onto the positioning mechanism of the second tray. S4 After the rubber strip on the positioning mechanism of the first tray is processed, the lifting mechanism lowers the positioning mechanism of the second tray, and the alternating drive mechanism moves again, driving the upper sliding frame and the lower sliding frame to move alternately in the horizontal direction, so that the positioning mechanism of the second tray moves the rubber strip to be processed on it horizontally to the processing station, and then the lifting mechanism raises it to the set height. Simultaneously, the positioning mechanism of the first tray moves the processed rubber strip back to the loading and unloading station. S5 manually removes the processed adhesive strip from the positioning mechanism of the first pallet, completing the unloading process.

[0015] This invention discloses a device and method for loading and unloading automotive seat adhesive strips. Two connecting rods connect a left side panel and a right side panel. An upper sliding frame slides along two upper linear guide rails, and a lower sliding frame slides along two lower linear guide rails. The lower sliding frame is located on a horizontal plane below the upper sliding frame. The upper sliding frame supports a first tray, and the lower sliding frame supports a second tray via a lifting mechanism. Driven by the lifting mechanism, the second tray can be raised and lowered. Both the first and second trays are equipped with positioning mechanisms for positioning several adhesive strips to be processed during loading. An alternating drive mechanism drives the upper and lower sliding frames to move alternately at different horizontal heights, achieving positional alternation. Before each alternation, the lifting mechanism lowers the second tray so that the positioning mechanism on the second tray is lower than the upper sliding frame, preventing interference during crossing. For example, initially, the first pallet is in front, at the loading / unloading station, and the second pallet is behind, at the processing station, and its height is much lower than the first pallet. When a position switch is needed, the alternating drive mechanism drives the upper sliding frame to slide backward and the lower sliding frame to slide forward, intersecting at different horizontal planes. The first pallet and the second pallet also intersect at different horizontal planes. Finally, the first pallet goes to the processing station at the rear, and the second pallet goes to the loading / unloading station at the front. Then, the lifting mechanism raises the second pallet to the same height as the first pallet, and loading / unloading can begin. When switching again, the lifting mechanism drives the second pallet to descend, and then the alternating drive mechanism drives the upper sliding frame and the lower sliding frame to alternate at different horizontal planes. The first pallet goes to the loading / unloading station, and the second pallet goes to the processing station. Then, the lifting mechanism raises the second pallet to the same height as the first pallet. In operation, the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism of the first tray; the lifting mechanism lowers the positioning mechanism of the second tray, and the alternating drive mechanism drives the upper sliding frame and the lower sliding frame to move alternately in the horizontal direction, so that the positioning mechanism of the first tray carries the adhesive strips to be processed to the processing station, and the positioning mechanism of the second tray arrives at the loading / unloading station; the lifting mechanism raises the positioning mechanism of the second tray to a set height, and the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism of the second tray; when the adhesive strips on the positioning mechanism of the first tray have been processed, the lifting mechanism... The positioning mechanism of the second tray is lowered, and the alternating drive mechanism is activated again, driving the upper sliding frame and the lower sliding frame to move alternately in the horizontal direction. This causes the positioning mechanism of the second tray to move the rubber strip to be processed horizontally to the processing station, where it is then raised to a set height by the lifting mechanism. Simultaneously, the positioning mechanism of the first tray drives the processed rubber strip back to the loading / unloading station. The processed rubber strip is manually removed from the positioning mechanism of the first tray to complete the unloading. This cycle continues, allowing for simultaneous processing and loading / unloading, thus enabling continuous alternating operation of two workstations and significantly improving production efficiency.

[0036] Furthermore, the two connecting rods 3 are respectively fixedly disposed between the left vertical plate 1 and the right vertical plate 2; the two upper linear guide rails 4 are respectively fixedly disposed on the left vertical plate 1 and the right vertical plate 2; the two lower linear guide rails 5 are respectively fixedly disposed on the left vertical plate 1 and the right vertical plate 2, and located below the two upper linear guide rails 4. The upper sliding frame 6 is slidably mounted on the two upper linear guide rails 4; the first tray 7 is fixedly mounted on the top of the upper sliding frame 6; the lower sliding frame 8 is slidably mounted on the two lower linear guide rails 5; the lifting mechanism 9 is mounted on the lower sliding frame 8; the second tray 10 is mounted on the lifting mechanism 9, and the lifting mechanism 9 is used to drive the second tray 10 to rise and fall. The two positioning mechanisms 11 are respectively disposed on the first tray 7 and the second tray 10; the alternating drive mechanism 12 is disposed on the left upright plate 1 and is used to drive the upper sliding frame 6 and the lower sliding frame 8 to move alternately in the horizontal direction.

[0037] In this embodiment, the two connecting rods 3 are used to connect the left upright plate 1 and the right upright plate 2; the upper sliding frame 6 slides along the two upper linear guide rails 4, and the lower sliding frame 8 slides along the two lower linear guide rails 5. The lower sliding frame 8 is on a horizontal plane below the upper sliding frame 6; the upper sliding frame 6 supports the first tray 7, and the lower sliding frame 8 supports the second tray 10 through the lifting mechanism 9. Under the drive of the lifting mechanism 9, the second tray 10 can be raised and lowered. The first tray 7 and the second tray 10 are both provided with the positioning mechanism 11, which is used to position and place several rubber strips to be processed during loading; the alternating drive mechanism 12 can drive the upper sliding frame 6 and the lower sliding frame 8 to move alternately back and forth at different horizontal heights to achieve position alternation; before each alternation, the lifting mechanism 9 must first lower the second tray 10 so that the positioning mechanism 11 on the second tray 10 is lower than the upper sliding frame 6 to avoid interference when they cross over; For example, initially, the first pallet 7 is in front, at the loading / unloading station, and the second pallet 10 is behind, at the processing station, with its height much lower than the first pallet 7. When a position switch is needed, the alternating drive mechanism 12 drives the upper sliding frame 6 to slide backward and the lower sliding frame 8 to slide forward, intersecting at different horizontal planes. The first pallet 7 and the second pallet 10 also intersect at different horizontal planes. Finally, the first pallet 7 goes to the processing station at the rear, and the second pallet 10 goes to the loading / unloading station at the front. Then, the lifting mechanism 9 raises the second pallet 10 to the same height as the first pallet 7, and loading / unloading can begin. When switching again, the lifting mechanism 9 drives the second pallet 10 to descend, and then the alternating drive mechanism 12 drives the upper sliding frame 6 and the lower sliding frame 8 to alternate at different horizontal planes. The first pallet 7 goes to the loading / unloading station, and the second pallet 10 goes to the processing station. Then, the lifting mechanism 9 raises the second pallet 10 to the same height as the first pallet 7. In use, the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism 11 of the first tray 7; the lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10, and the alternating drive mechanism 12 drives the upper sliding frame and the lower sliding frame 8 to move alternately in the horizontal direction, so that the positioning mechanism 11 of the first tray 7 carries the adhesive strips to be processed to the processing station, and the positioning mechanism 11 of the second tray 10 arrives at the loading and unloading station; the lifting mechanism 9 raises the positioning mechanism 11 of the second tray 10 to a set height, and the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism 11 of the second tray 10; when the adhesive strips on the positioning mechanism 11 of the first tray 7 have been processed, The lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10, and the alternating drive mechanism 12 actuates again, driving the upper sliding frame 6 and the lower sliding frame 8 to move alternately in the horizontal direction again. This causes the positioning mechanism 11 of the second tray 10 to move the rubber strip to be processed horizontally to the processing station, and then the lifting mechanism 9 drives it to rise to the set height. Simultaneously, the positioning mechanism 11 of the first tray 7 drives the processed rubber strip back to the loading and unloading station. The operator removes the processed rubber strip from the positioning mechanism 11 of the first tray 7 to complete the unloading. This cycle continues, allowing for simultaneous processing and loading and unloading. This enables continuous alternating operation of two workstations, significantly improving production efficiency.

[0038] Furthermore, the front U-shaped photoelectric sensor 13 is fixedly mounted on the right side upright plate 2; the rear U-shaped photoelectric sensor 14 is fixedly mounted on the right side upright plate 2; and the side limiting plate 15 is fixedly mounted on the side of the lower sliding frame 8 near the right side upright plate 2.

[0039] In this embodiment, the side limiting plate 15 follows the lower sliding frame 8 on one side, and works with the front U-shaped photoelectric sensor 13 and the rear U-shaped photoelectric sensor 14 to detect whether the lower sliding frame 8 and the upper sliding frame 6 have alternately entered their positions. When the side limiting plate 15 moves into the rear U-shaped photoelectric sensor 14, the rear U-shaped photoelectric sensor 14 will sense it, indicating that the lower sliding frame 8 has moved to the processing station, and the corresponding upper sliding frame 6 is in the loading / unloading station. When the side limiting plate 15 moves into the front U-shaped photoelectric sensor 13, the front U-shaped photoelectric sensor 13 will sense it, indicating that the lower sliding frame 8 has moved to the loading / unloading station, and the corresponding upper sliding frame 6 is in the processing station.

[0040] Furthermore, the placement plate 111 is provided with a mounting cavity 1111; the synchronization block 112 is slidably disposed in the mounting cavity 1111; the synchronization block 112 has an inclined surface 1121; a plurality of spacers 113 are respectively fixedly disposed on the top of the synchronization block 112 and respectively penetrate the placement plate 111; the slider 114 is slidably disposed in the mounting cavity 1111; two grips 115 are respectively fixedly disposed on both sides of the slider 114 and respectively penetrate the placement plate 111; the fixing block 116 is fixedly disposed on the top of the placement plate 111; the sliding rod 117 is slidably disposed on the fixing block 116 and penetrates the fixing block 116; the alignment plate 118 is fixedly disposed on one side of the sliding rod 117.

[0041] In this embodiment, the placement plate 111 is fixed on the first tray 7 or the second tray 10, and two adjacent spacers 113 can cooperate to linearly position a rubber strip. In use, the two grips 115 are held from the left and right, and pushed backward. The slider 114 will then press and push the synchronization block 112 upward along the inclined surface 1121. The synchronization block 112 then drives multiple spacers 113 to extend out of the mounting cavity 1111. Then, the alignment plate 118 is moved closer to the ends of the multiple spacers 113. Finally, the spacers can be manually... One by one, the adhesive strips are placed between the two spacers 113, with the ends of the adhesive strips abutting against the alignment plate 118, so that the multiple adhesive strips are aligned and placed in a straight line. After placement, the alignment plate 118 is pushed away from the multiple adhesive strips. Then, the two grips 115 are held from the left and right and pulled backward. The slider 114 will gradually release the synchronization block 112. The synchronization block 112 drives the multiple spacers 113 to retract into the mounting cavity 1111. The alignment plate 118 and the multiple spacers 113 are all away from the adhesive strips to avoid obstructing the adhesive strips during processing.

[0042] Furthermore, the four lifting guide shafts 91 are slidably mounted on the lower sliding frame 8 and pass through the lower sliding frame 8 respectively; the lifting base plate 92 is fixedly mounted on the top of the four lifting guide shafts 91 and is fixedly connected to the second tray 10; the two cylinders 93 are fixedly mounted on the lower sliding frame 8 respectively, and the output ends of the two cylinders 93 are fixedly connected to the lifting base plate 92.

[0045] In this embodiment, the two first hydraulic dampers 94 are used to prevent rigid collisions from occurring when the lifting base plate 92 descends beyond the set stroke, thus providing a buffering effect. The two second hydraulic dampers 96 are used to prevent rigid collisions from occurring when the lifting base plate 92 rises beyond the set stroke, thus providing a buffering effect.

[0046] Furthermore, the vertical mounting block 97 is fixedly mounted on the lower sliding frame 8; the upper U-shaped photoelectric sensor 98 is fixedly mounted on the top of the vertical mounting block 97; the lower U-shaped photoelectric sensor 99 is fixedly mounted on the bottom of the vertical mounting block 97; the upper limit plate 910 is fixedly mounted on the bottom of the lifting base plate 92; and the lower limit plate 911 is fixedly mounted on the top of the support plate 95 near the left side upright plate 1.

[0047] In this embodiment, when the lifting base plate 92 descends, it causes the upper limit plate 910 to move downwards. When the upper limit plate 910 moves into the upper U-shaped photoelectric sensor 98, the upper U-shaped photoelectric sensor 98 will sense it, indicating that the descent has reached the correct position. When the lifting base plate 92 rises, the lower limit plate 911 moves upwards accordingly. When the lower limit plate 911 moves into the lower U-shaped photoelectric sensor 99, the lower U-shaped photoelectric sensor 99 will sense it, indicating that the rise has reached the correct position.

[0048] Furthermore, the servo motor 121 is fixedly mounted on the left side upright plate 1; the drive pulley 122 is fixedly mounted on the output end of the servo motor 121; the mounting member 123 is mounted on the left side upright plate 1; the rotating shaft 124 is rotatably mounted on the mounting member 123; the driven pulley 125 is fixedly mounted on one end of the rotating shaft 124; the toothed belt 126 is mounted on the drive pulley 122 and the driven pulley 125; one of the connecting members 127 is used to connect the upper sliding frame 6 and the toothed belt 126, and the other connecting member 127 is used to connect the lower sliding frame 8 and the toothed belt 126.

[0049] In this embodiment, the servo motor 121 drives the active pulley 122 to rotate, and the active pulley 122 drives the driven pulley 125 to rotate through the toothed belt 126. One of the connecting members 127 is connected above the toothed belt 126 and connects to the upper sliding frame 6, and the other connecting member 127 is connected below the toothed belt 126 and connects to the lower sliding frame 8. When the toothed belt 126 moves, the two connecting members 127 drive the upper sliding frame 6 and the lower sliding frame 8 to slide in opposite directions on horizontal planes at different heights.

[0050] Furthermore, the left upright plate 1 is provided with a strip-shaped hole 101; two guide blocks 1231 are respectively fixedly mounted on the left upright plate; the adjusting block 1232 is slidably mounted on the two guide blocks 1231; the bearing seat 1233 is fixedly mounted on the adjusting block 1232 and is rotatably connected to the rotating shaft 124 through the bearing, and passes through the strip-shaped hole 101; the tensioning block 1234 is fixedly mounted on the left upright plate 1; two guide rods 1235 are respectively fixedly connected to the adjusting block 1232 and slidably connected to the tensioning block 1234, and respectively pass through the tensioning block 1234; two springs 1236 are respectively sleeved on the two guide rods 1235 and located between the tensioning block 1234 and the adjusting block 1232, and the two springs 1236 are in a compressed state.

[0051] In this embodiment, the adjusting block 1232 can slide on the two guide blocks 1231, and the corresponding bearing seat 1233 moves within the strip hole 101. After assembly, the two springs 1236 are in a compressed state, giving the adjusting block 1232 an elastic force, causing the driven pulley 125 to tend to move away from the driving pulley 122, thereby tightening the toothed belt 126. When the toothed belt 126 loosens, the spring 1236 drives the driven pulley 125 away from the driving pulley 122, tightening the toothed belt 126 again, thus achieving dynamic tightening of the toothed belt 126.

[0052] Furthermore, the fixing plate 1272 is fixedly disposed on one side of the connecting plate 1271; the clamping plate 1273 is located on one side of the fixing plate 1272, and the clamping plate 1273 has a plurality of meshing teeth 12731; a plurality of threaded rods 1274 are respectively fixedly disposed on the fixing plate 1272 and respectively penetrate the clamping plate 1273; a plurality of nuts 1275 are respectively threaded onto the plurality of threaded rods 1274.

[0053] In this embodiment, the connecting plate 1271 is fixedly connected to the upper sliding frame 6 or the lower sliding frame 8. Multiple threaded rods 1274 and multiple nuts 1275 cooperate to clamp the fixing plate 1272 and the clamping plate 1273 onto the toothed belt 126. The fixing plate 1272 is attached to the toothless side of the toothed belt 126, and the clamping plate 1273 is attached to the toothed side of the toothed belt 126. Multiple meshing teeth 12731 mesh with the teeth of the toothed belt 126, thus preventing slippage.

[0054] In this embodiment, an automotive seat adhesive strip loading and unloading device is described. During use, the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism 11 of the first tray 7. The lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10, and the alternating drive mechanism 12 drives the upper sliding frame and the lower sliding frame 8 to move alternately in the horizontal direction. This causes the positioning mechanism 11 of the first tray 7 to carry the adhesive strips to be processed to the processing station, and the positioning mechanism 11 of the second tray 10 to the loading and unloading station. The lifting mechanism 9 then raises the positioning mechanism 11 of the second tray 10 to a set height, and the operator manually places the adhesive strips to be processed one by one onto the positioning mechanism 11 of the second tray 10. When the positioning mechanism 11 of the first tray 7... After the adhesive strip is processed, the lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10. The alternating drive mechanism 12 then operates again, driving the upper sliding frame 6 and the lower sliding frame 8 to move alternately in the horizontal direction. This causes the positioning mechanism 11 of the second tray 10 to move the adhesive strip to be processed horizontally to the processing station. Then, the lifting mechanism 9 raises it to a set height. Simultaneously, the positioning mechanism 11 of the first tray 7 drives the processed adhesive strip back to the loading / unloading station. The operator removes the processed adhesive strip from the positioning mechanism 11 of the first tray 7 to complete the unloading. This cycle continues, allowing for simultaneous processing and loading / unloading. This enables continuous alternating operation at two workstations, significantly improving production efficiency.

[0055] The second embodiment of this application is as follows: Based on the first embodiment, please refer to Figure 16 ,in, Figure 16 This is a flowchart illustrating the second embodiment of the present invention.

[0056] This invention provides a method for loading and unloading automotive seat adhesive strips, comprising: S1 The manual person places the strips to be processed one by one onto the positioning mechanism 11 of the first tray 7; S2 lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10, and the alternating drive mechanism 12 drives the upper sliding frame 6 and the lower sliding frame 8 to move alternately in the horizontal direction, so that the positioning mechanism 11 of the first tray 7 carries the rubber strip to be processed to the processing station, and the positioning mechanism 11 of the second tray 10 comes to the loading and unloading station. The S3 lifting mechanism 9 raises the positioning mechanism 11 of the second tray 10 to a set height, and the manual person places the strips to be processed one by one onto the positioning mechanism 11 of the second tray 10; S4 After the rubber strip on the positioning mechanism 11 of the first tray 7 is processed, the lifting mechanism 9 lowers the positioning mechanism 11 of the second tray 10, and the alternating drive mechanism 12 operates again, driving the upper sliding frame 6 and the lower sliding frame 8 to move alternately in the horizontal direction again, so that the positioning mechanism 11 of the second tray 10 drives the rubber strip to be processed on it to move horizontally to the processing station, and then the lifting mechanism 9 drives it to rise to the set height. Simultaneously, the positioning mechanism 11 of the first tray 7 drives the processed rubber strip back to the loading and unloading station. S5 manually removes the processed adhesive strip from the positioning mechanism 11 of the first tray 7, completing the unloading process.
