Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, in particular to a felt seam pressing device. Background Art

[0002] Pressing felt onto car interior panels is a commonly used process in the automobile manufacturing process. Felt has good sound absorption effect, can reduce noise inside the car, provide a quieter and more comfortable environment for drivers and passengers, and can also play a certain role in heat preservation in cold weather. Existing pressing devices mainly press felt by gluing, hot pressing, molding and other methods.

[0003] Among them, the gluing method requires coating adhesive on the outer surface of the car interior panel, and then manually pressing the felt cloth to effectively stick to the car interior panel. However, there are larger-sized car roof panels in the car interior panels. When the felt cloth is manually pressed on the car roof panel, in order to effectively adhere the felt cloth to the car roof panel, it is necessary to adjust the pressing force of the felt cloth. The felt cloth will be pressed on the car roof panel by rolling, but such operation is inefficient, and if the force is too great, it will cause excessive squeezing of the car roof panel, which will cause deformation and damage of the car roof panel, increasing processing costs.

[0048] like Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, the two fixed platforms 51 are rotatably connected to a rotating disk 6 at one end away from the pillar 1, and a rotating shaft 61 is fixedly connected between the two rotating disks 6. A felt cloth 62 is wound on the outer surface of the rotating shaft 61, and the end of the felt cloth 62 away from the rotating shaft 61 passes between the two positioning rollers 54.

[0050] like Figure 1 and Fig.12As shown, a cutting assembly for cutting the felt cloth 62 is provided on the lower pressure plate 42, and the cutting assembly includes an electric slide rail 81. The side of the lower pressure plate 42 away from the release frame 717 is fixedly connected to the electric slide rail 81, and the bottom of the electric slide rail 81 is slidably connected to an electric slider 82, and the bottom of the electric slider 82 is fixedly connected to a cutting knife 83.

[0051] In combination with the above preferred embodiments, the following is the entire working process and working principle of the above embodiments:

[0052] The initial state is:

[0053] The sliding frame 75 has not moved to be squeezed with the pushing plate 510, and the spring two 77 has not been stretched. At this time, the push-pull rod 78 is in a tilted state. The push-pull rod 78 makes the two clamping plates 79 respectively at the highest position and the lowest position on the inner side of the traction frame 73 through the connecting rod 711. The block 714 is not aligned with the hole 716. The spring three 713 makes the block 714 at the highest position of the spring cavity 712, and the telescopic axis of the electric telescopic rod 41 does not extend downward.

[0054] The working status is:

[0055] A car roof panel is placed on the external conveyor belt, and a layer of adhesive has been coated on the upward side of the car roof panel for adhering the felt cloth 62 to the car roof panel. The staff pulls the felt cloth 62 so that the felt cloth 62 passes through the two positioning rollers 54, and the part of the felt cloth 62 passing through the positioning rollers 54 rests on the sub-rod of the bracket 511. The soft rubber parts of the two positioning rollers 54 will come into contact with the upper and lower surfaces of the felt cloth 62.

[0056] The feeding assembly transfers the automobile roof panel to the pressing table 21:

[0057] A car roof panel is conveyed to the right extension plate 13 by an external conveyor belt, and then the staff starts the motor 33, and the output shaft of the motor 33 rotates counterclockwise (the counterclockwise direction here refers to Figure 2), the motor 33 drives the rotating shaft 34 to rotate counterclockwise synchronously through the belt 35, and the output shaft of the motor 33 and the rotating shaft 34 drive the feeding rod 37 to swing counterclockwise through the swing rod 36. When the feeding rod 37 swings upward, it will conflict with the car roof board on the extension plate 13, and the car roof board is lifted by the upward rotation movement of the feeding rod 37. At the same time, the side rods 371 on both sides of the feeding rod 37 are used to auxiliary support the car roof board to prevent the car roof board from being lifted when the car roof board is lifted. The feeding rod 37 is skewed. In addition, due to the counterclockwise swing of the feeding rod 37, the feeding rod 37 will swing to the left, thereby realizing the lifting and transportation of the automobile roof panel. Through multiple counterclockwise swings of the feeding rod 37, the automobile roof panel gradually moves onto the pressing table 21. When the automobile roof panel moves to a position that coincides with the position of the pressing table 21, the motor 33 is turned off, so that the feeding rod 37 stops the lifting and transportation work of the automobile roof panel. At this time, the transportation work of the automobile roof panel is realized, and the automatic feeding step is realized.

[0058] The pulling component pulls the felt cloth 62:

[0059] Start the electric slide rail 71, and the electric slide rail 71 drives the guide rod 72 to move toward the side close to the positioning roller 54, and the guide rod 72 drives the traction frame 73 to move synchronously, and the traction frame 73 drives the inner clamping plate 79 to move synchronously. When the clamping plate 79 moves to the end of the felt cloth 62 located above the bracket 511, the sliding frame 75 will conflict with the pushing plate 510. The sliding frame 75 cannot move after being conflicted by the pushing plate 510. When the traction frame 73 continues to move toward the side close to the positioning roller 54, the sliding frame 75 will slide along the slide groove 74, and the traction frame 73 will stretch the spring 2 77 through the connecting plate 76. The traction frame 73 will also drive the convex strip 715 to move synchronously. The convex strip 71 When the locking nut 716 is moved to the upper part of the locking nut 714, the locking nut 714 is moved upwardly by the elastic return action of the spring 713, and the locking nut 714 is inserted into the inner part of the locking nut 716 and is engaged with the locking nut 716; at the same time, when the traction frame 73 drives the clamping plate 79 to move, the clamping plate 79 pushes the push-pull rod 78 through the connecting rod 711 to rotate the push-pull rod 78, and the push-pull rod 78 rotates, and the two clamping plates 79 are driven to move closer to each other when the push-pull rod 78 rotates to a vertical state. The pressing groove 710 on 79 will fit with the auxiliary rod of the bracket 511, and the two clamping plates 79 will clamp the felt cloth 62. That is, when the clamping block 714 is clamped with the clamping hole 716, the push-pull rod 78 rotates to a vertical state, so that the two clamping plates 79 clamp the felt cloth 62. At this time, the sliding frame 75 uses the push-pull rod 78 and the connecting rod 711 to keep the two clamping plates 79 clamping the felt cloth 62 at all times. After the clamping plates 79 clamp the felt cloth 62, the electric slide rail 71 drives the guide rod 72 to move to the side away from the positioning roller 54, and the guide rod 72 drives the traction frame 73 to move synchronously, and the traction frame 73 drives the clamping plates 79 on its inner side to move synchronously to the side away from the positioning roller 54. The clamping plate 79 will pull the felt cloth 62, and the felt cloth 62 will drive the rotating disk 6 to rotate on the fixed platform 51 through the rotating shaft 61, so that the felt cloth 62 is unfolded, and when the traction frame 73 moves to the side of the pillar 1 away from the positioning roller 54, the felt cloth 62 can cover the top of the automobile roof panel on the pressing table 21, thereby achieving the effect of automatically covering the felt cloth 62, reducing the steps required for manual placement, ensuring that the felt cloth 62 is accurately laid at the specified position of the automobile roof panel, avoiding the position deviation, skewness and other problems that may occur during manual laying, and avoiding the occurrence of wrinkles and unevenness when the felt cloth 62 is manually laid, and the tedious steps of manually pulling and adjusting the position are avoided.

[0060] Positioning the pulled felt cloth 62:

[0061] When the felt cloth 62 moves and unfolds, the felt cloth 62 will drive the two positioning rollers 54 that are in conflict with it to rotate on the positioning platform 53. During the rotation, the positioning rollers 54 will drive the ratchet 56 to rotate through the baffle plate 55. The rotation of the ratchet 56 will continuously squeeze the ratchet bar 59 to make it continuously move into the positioning groove block 57. The ratchet bar 59 will continuously compress the spring 58. When the felt cloth 62 completely covers the top of the automobile roof panel on the pressing platform 21, the felt cloth 62 stops moving and unfolds. The ratchet bar 59 will conflict with the adjacent ratchet wheel 56 under the elastic action of the spring 58, thereby being able to achieve the clamping of the ratchet wheel 56 to prevent the ratchet wheel 56 from rotating in the opposite direction, and then the baffle plate 55 and the positioning roller 54 can be used to restrict the felt cloth 62 in the opposite direction to prevent the felt cloth 62 from moving back to the side away from the traction frame 73. By providing two positioning rollers 54 and two clamping plates 79, the felt cloth 62 can be kept in a flat state.

[0062] The pressing assembly presses the felt cloth 62 onto the automobile roof panel:

[0063] When the electric telescopic rod 41 is started, the telescopic shaft of the electric telescopic rod 41 will extend downward, the electric telescopic rod 41 will drive the lower pressing plate 42 to move downward, and the lower pressing plate 42 will drive the sliding rod 45 to slide downward in the stable groove 44. Under the guidance of the stable groove 44, the lower pressing plate 42 can move downward stably. At the same time, the downward movement of the lower pressing plate 42 will drive the pressing pad 43 to move downward synchronously. The pressing pad 43 will contact the felt cloth 62 when it moves downward, and the pressing pad 43 will push the felt cloth 62 when it continues to move downward. The downward movement allows the felt cloth 62 to fit with the car roof panel on the pressing table 21. Combined with the soft rubber material of the pressing pad 43, the felt cloth 62 can adapt to the shape of the car roof panel for overall fitting, and the fitting speed is faster. At the same time, the soft rubber material of the pressing pad 43 can adapt to car roof panels of any shape, so that the pressure on the felt cloth 62 is more uniform. The shape of the pressing table 21 is set corresponding to the car roof panel, which can support the car roof panel and avoid excessive pressing of the car roof panel.

[0064] The release frame 717 releases the engagement relationship between the block 714 and the hole 716:

[0065] When the lower pressure plate 42 moves downward, the lower pressure plate 42 will drive the release frame 717 to move downward synchronously. After the release frame 717 moves downward, the two ends of its C-shaped rod will be inserted into the inside of the clamping hole 716, and the release frame 717 will push the clamping block 714 to make it move downward. When the clamping block 714 moves downward, it will compress the spring three 713. At this time, the clamping block 714 cannot be clamped with the clamping hole 716. At the same time, under the elastic reset action of the spring two 77, the sliding frame 75 moves along the sliding groove 74 to the side close to the positioning roller 54. The sliding frame 75 will drive the two clamping plates 79 to move away from each other through the push-pull rod 78 and the connecting rod 711. At this time, the two clamping plates 79 no longer clamp the felt cloth 62.

[0066] Cutting kit for cutting felt cloth 62:

[0067] When the lower pressure plate 42 moves downward, the lower pressure plate 42 will drive the electric slide rail 2 81 to move downward synchronously, and the electric slide rail 2 81 will drive the electric slider 82 and the cutting knife 83 to move downward synchronously. When the lower pressure plate 42 presses the felt cloth 62 onto the car roof panel, the cutting knife 83 will penetrate into the felt cloth 62, and then the electric slide rail 2 81 will be started, and the electric slide rail 2 81 will drive the electric slider 82 to move. The movement of the electric slider 82 will drive the cutting knife 83 to move synchronously, so that the cutting knife 83 that has penetrated into the felt cloth 62 will cut the felt cloth 62, thereby realizing automatic cutting of the felt cloth 62, and can cut at a stable speed and precise size.

[0068] It should be noted that Figure 1 The left side is the unloading side, and the right side is the loading side. After the felt cloth 62 is bonded to the car roof panel on the pressing table 21, the feeding assembly will be opened to gradually transfer the car roof panel on the pressing table 21 to the extension plate 13 on the left and the external conveyor belt for unloading. After unloading, the excess felt cloth on the car roof panel needs to be cut and trimmed.
