AI Technical Summary
但是，汽车顶篷端部5有时会意外折叠变厚，如图2所示，导致副压板22对汽车顶篷端部5施压时被顶至翘起，该趋势传递到横连接杆11，横连接杆11容易因为杠杆效应而朝上弯曲损坏，导致副压板22也随之长期翘起损坏
[0010]有益效果在于：副压板压在意外折叠变厚的汽车顶篷端部时会被顶起从而绕转轴暂时朝上转动退让。因为副压板装在转轴上能够绕转轴转动，不存在刚性连接结构，所以不会如背景技术那样导致刚性连接结构弯曲，避免副压板长期翘起损坏。操作人员看到副压板意外被顶起，就会检查汽车顶篷端部余料，发现是因为汽车顶篷端部余料意外折叠变厚，于是把汽车顶篷端部余料抚平，让副压板受重力作用朝下转动复位。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile roof manufacturing, and in particular to a component placement device for the edge cutting process of automobile roofs. Background Technology
[0002] Existing automotive roof trimming process component placement devices, such as Figure 1 As shown, it includes a placement mold 4, with the middle part 3 of the placement mold positioned higher than the two ends 1 of the placement mold. A car roof body 8 is placed on the placement mold 4, the middle part 6 of the car roof is placed on the top wall of the middle part 3 of the placement mold, and the two ends 5 of the car roof are respectively placed on the top walls of the two ends 1 of the placement mold. A cutting line 7 is provided near the edge of the end 5 of the car roof, and the portion between the cutting line 7 and the edge of the end 5 of the car roof is the end material 9.
[0003] A main pressure plate 10 is located directly above the center section 6 of the car roof. The main pressure plate 10 is mounted on the bottom wall of the vertical drive rod 15 of the vertical cylinder 14, which is fixed to the ceiling. Each end of the main pressure plate 10 has a horizontal connecting rod 11. A vertical connecting rod 12 is mounted on the end of the horizontal connecting rod 11 furthest from the main pressure plate 10, and a secondary pressure plate 22 is mounted on the bottom wall of the vertical connecting rod 12. The main pressure plate 10 is driven downwards by the vertical drive rod 15, pressing the center section 6 of the car roof against the top wall of the placement mold center section 3. During the downward movement of the main pressure plate 10, the secondary pressure plate 22 is also moved downwards, pressing the non-end excess material 9 of the corresponding end section 5 of the car roof against the top wall of the corresponding placement mold end section 1. The placement device for the car roof trimming process also includes a cutting robot (not shown in the figure). The cutting robot cuts along the cutting line 7 on the end section 5 of the car roof, discarding the cut end excess material 9. However, the end section 5 of the car roof may sometimes accidentally fold and thicken, such as... Figure 2 As shown, when the sub-pressure plate 22 applies pressure to the end 5 of the car roof, it is pushed up and lifted. This tendency is transmitted to the horizontal connecting rod 11, which is prone to bending and damage due to the leverage effect, causing the sub-pressure plate 22 to also be lifted up and damaged over a long period of time. Utility Model Content
[0004] The present invention aims to provide a device for the trimming process of car roofs, wherein the auxiliary pressure plate will not be permanently lifted and damaged when pressing on the end of the car roof that has been accidentally folded and thickened.
[0005] The placement device for the trimming process of an automobile roof includes a placement mold, with the middle part of the placement mold positioned higher than the two ends. A main pressure plate is positioned directly above the middle part of the placement mold and is mounted on the bottom wall of the vertical drive rod of the fixed vertical cylinder above it. The top wall of the middle part of the placement mold is used to place the middle part of the automobile roof. The main pressure plate is pressed against the top wall of the middle part of the placement mold by the pressure of the vertical drive rod. The top wall of the end of the placement mold is used to place the end of the automobile roof laterally. A front-to-back lateral rotating shaft is provided on the side of the end of the top wall of the placement mold where the end of the automobile roof is placed. A front-to-back lateral auxiliary pressure plate is positioned directly above the part of the end of the placement mold near the end of the end of the automobile roof. The auxiliary pressure plate is mounted on the rotating shaft and presses the part of the end of the automobile roof against the top wall of the end of the placement mold. If the end of the automobile roof is accidentally folded and thickened and pushed upwards, the auxiliary pressure plate will rotate upwards around the rotating shaft to retract.
[0006] Furthermore, a horizontal cylinder is provided between the auxiliary pressure plate and the rotating shaft, and the auxiliary pressure plate is specifically installed on the rotating shaft through the horizontal cylinder.
[0007] Furthermore, there are two horizontal cylinders, with the main bodies of the two horizontal cylinders respectively mounted on the side wall of the rotating shaft near both ends, and the horizontal drive rod of the horizontal cylinder is connected to the corresponding end of the auxiliary pressure plate.
[0008] Furthermore, the side wall of the horizontal cylinder body facing the other horizontal cylinder body is equipped with a slide rail in the same direction as its own length, and a slider is installed on the slide rail, with the two sliders aligned with each other; an end material pressure plate is provided between the two sliders on the two horizontal cylinder bodies, and the two ends of the end material pressure plate are installed on the two sliders to press the end material of the car roof onto the top wall of the mold end.
[0009] Furthermore, a gap is left between the secondary pressure plate and the end residual material pressure plate to allow the cutting robot to reach in and cut.
[0010] The beneficial effect is that when the sub-pressure plate presses on the end of the car roof that has been accidentally folded and thickened, it will be lifted up and temporarily rotate upwards around the pivot to retract. Because the sub-pressure plate is mounted on the pivot and can rotate around it, there is no rigid connection structure, so it will not cause the rigid connection structure to bend as in the prior art, thus avoiding long-term damage to the sub-pressure plate due to its tilting. When the operator sees the sub-pressure plate being accidentally lifted, they will check the excess material at the end of the car roof and find that it is because the excess material at the end of the car roof has been accidentally folded and thickened. They will then smooth out the excess material at the end of the car roof, allowing the sub-pressure plate to rotate downwards and reset under the action of gravity. Attached Figure Description

Detailed Implementation
[0012] The present invention will be further described in detail below with reference to specific embodiments.
[0013] like Figure 3 As shown, the placement device for the car roof trimming process includes left and right horizontal placement molds 4, with the middle part 3 of the placement mold positioned higher than the left and right ends. A main pressure plate 10 is located directly above the middle part 6 of the car roof. The main pressure plate 10 is mounted on the bottom wall of the vertical drive rod 15 of the upper vertical cylinder 14, which is fixed to the ceiling (not shown in the figure). Figure 4 and Figure 5As shown, both the left and right sides of the top wall of the mold end 1 are equipped with a front-to-back transverse rotating shaft 20 near their respective ends. The front end of the rotating shaft 20 has a left-to-right transverse cylinder 21, and the rear end also has a left-to-right transverse cylinder 21. The main bodies of the front and rear transverse cylinders 21 on this rotating shaft 20 are fixedly mounted on the inner sidewall of the rotating shaft 20 near their respective ends. The auxiliary pressure plate 22 is front-to-back transverse, with its front and rear ends respectively mounted on the ends of the two transverse drive rods 26. In each of the two transverse cylinders 21, the sidewall facing the other transverse cylinder 21 is equipped with a slide rail 23 running in the same direction as its own length. A slider 24 is mounted on the slide rail 23. The front and rear sliders 24 on these two transverse cylinders 21 are aligned with each other. The end material pressure plate 25 is front-to-back transverse, with its front and rear ends respectively mounted on the front and rear sliders 24.
[0014] like Figure 3 and Figure 4 As shown, a horizontally oriented car roof body 8 is placed on the placement mold 4. The middle part 6 of the car roof is placed on the top wall of the middle part 3 of the placement mold and is pressed down by the main pressure plate 10, which has been driven downward by the vertical cylinder 14. A cutting line 7 is provided near the end edge of the end of the car roof 5, and the part between the cutting line 7 and the end edge is the end material 9. The left and right ends 5 of the car roof are placed on the top walls of the left and right ends 1 of the placement mold 4, respectively. The end of the car roof 5 near the cutting line 7 is pressed down by the auxiliary pressure plate 22, and the end material 9 of the car roof is pressed down by the end material pressure plate 25. If the end material 9 of the car roof is as follows... Figure 2 Such an accidental folding causes the end portion 5 of the car roof to thicken, causing the sub-pressure plate 22 to be pushed upwards by the unexpectedly thickened end portion 5, thus temporarily rotating upwards around the pivot 20. Because the sub-pressure plate 22 is mounted on the pivot 20 and can rotate around it, there is no rigid connection structure, so it will not cause the rigid connection structure to bend as in the prior art, avoiding long-term damage to the sub-pressure plate 22 due to its tilted position. When the operator sees the sub-pressure plate 22 being accidentally lifted, they will check the remaining material 9 at the end portion of the car roof. If they find that it is due to the unexpected folding and thickening of the remaining material 9 at the end portion of the car roof, they will smooth the remaining material 9 back to its original state, allowing the sub-pressure plate 22 to rotate downwards and return to its original position under the influence of gravity. Figure 3 The state shown.
[0015] A cutting robot (not shown in the figure) is installed above the placement device. The cutting robot extends into the gap between the sub-pressure plate 22 and the end material pressure plate 25, and cuts out the end material 9 along the cutting line 7. The sub-pressure plate 22 and the end material pressure plate 25 are driven by the operator to synchronously rotate 180 degrees outward around the corresponding pivot 20 to release the end of the car roof 5. Figure 6As shown. The operator can then remove and discard the end excess material 9, and remove and store the main body 8 of the car roof. To manufacture other models of car roofs, the operator manipulates the horizontal cylinder 21 to extend / retract the horizontal drive rod 26, causing the auxiliary pressure plate 22 to move laterally left and right. Simultaneously, the operator manipulates the slider 24, together with the end excess material pressure plate 25, to move laterally left and right along the slide rail 23. This allows the end excess material pressure plate 25 and / or the auxiliary pressure plate 22 to move laterally left and right to adjust the gap between them, adapting to the different cutting line positions of other models of car roofs.
[0016] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on this utility model will still fall within the scope of patent protection.
