Description

Technical Field

[0001] This invention relates to the field of automotive headliner foam bonding, and more specifically to an automotive headliner foam positioning and bonding device. Background Technology

[0002] The car roof is part of the car interior. It is generally composed of a non-woven fabric layer, a fiberglass layer, a foam layer, a fiberglass layer, and a non-woven fabric layer. Most car roofs use PU foam for the foam layer. In the process of molding the car roof, the layers first need to be glued together. After the glue is applied, the roof undergoes a hot pressing process and a cutting process to finally produce the finished car roof.

[0003] Currently, in the process of applying adhesive to bond the fiberglass layer and non-woven fabric layer to automotive headliner foam, the general procedure is to first apply adhesive to one side of the foam, then attach the fiberglass layer, and finally attach the non-woven fabric layer. Each time this is done, adhesive needs to be reapplied. This process takes longer to bond the fiberglass and non-woven fabric layers to the automotive headliner foam. Furthermore, because adhesive needs to be reapplied, the area to which it is applied is prone to change, affecting efficiency and making it difficult to guarantee quality. Moreover, after bonding, it is difficult to immediately press the automotive headliner foam, fiberglass layer, and non-woven fabric layer together. Summary of the Invention

[0004] The purpose of this invention is to provide a positioning and pasting device for automotive headliner foam to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car headliner foam positioning and pasting device, comprising:

[0006] A support platform, with limiting frames for limiting the conveying of automotive roof foam fixed on both sides of the top of the support platform;

[0007] Two support frames are fixed to the top and bottom of the support platform, respectively. A non-woven fabric roller is installed on the side of the support frame away from the support platform, and a fiberglass cotton roller is installed on the side of the support frame closer to the support platform. The non-woven fabric roller and the fiberglass cotton roller are connected to the support frame by bearing rotation to ensure that the non-woven fabric roller and the fiberglass cotton roller can rotate during the traction process.

[0008] A fixing box is fixed to one side of a limiting frame. An X-shaped frame is installed inside the fixing box. A pressure roller is installed on one side of the X-shaped frame via a bearing. Two main applicator rollers for applying adhesive to automotive headliner foam are installed on the other side of the X-shaped frame via a connector.

[0009] A glue tank is fixed to one side of the support frame, and a glue supply mechanism for supplying glue to the main glue-applying wheel is provided between the glue tank and the main glue-applying wheel.

[0010] Preferably, the limiting frame has rectangular holes at both the top and bottom. A lower fixing frame is fixed in the bottom rectangular hole, and an upper fixing frame passes through the top rectangular hole. Limiting rollers are provided on opposite sides of the lower and upper fixing frames. A horizontal plate is fixed to the top of the upper fixing frame. Screws are fixed to the top of the limiting frame near its four corners. The screws pass through the horizontal plate, and nuts are threaded to the top and bottom of the horizontal plate on the outside of the screws.

[0011] Preferably, the X-shaped frame includes an upper movable plate and a lower movable plate, the upper movable plate and the lower movable plate are arranged in an X shape, and the upper movable plate and the lower movable plate are rotatably connected by bearings;

[0012] Two pressure rollers are provided, one of which is rotatably connected to the upper movable plate via a bearing, and the other is rotatably connected to the lower movable plate via a bearing.

[0013] The fixed box is equipped with an angle adjustment mechanism for adjusting the horizontal opening angle of the X-shaped frame, and slots for the movement of the X-shaped frame are provided on both the upper and lower sides of the fixed box.

[0014] Preferably, the angle adjustment mechanism includes a controller, a forward and reverse motor, and a sliding plate. The controller is installed outside the fixed box, the forward and reverse motor is fixed inside the fixed box, and a lead screw is installed on the drive shaft of the forward and reverse motor. The sliding plate is slidably connected inside the fixed box via a slide rail, and the lead screw is threadedly connected to the sliding plate.

[0015] Both the upper and lower movable plates have sliding blocks slidably connected to them via sliding grooves on one side inside the fixed box. A connecting rod is provided between the sliding block and the sliding plate, and the connecting rod is rotatably connected to both the sliding block and the sliding plate via bearings.

[0016] Preferably, one of the main glue-applying wheels is fixed to the upper movable plate by a connector, and the other main glue-applying wheel is fixed to the lower movable plate by a connector.

[0017] The outer wall of the main coating wheel is provided with a through hole for dispensing glue;

[0018] The connector includes a connecting column, one end of which is fixedly connected to the X-shaped frame. A fixing plate is fixed to one side of the connecting column relative to the X-shaped frame, and the fixing plate is rotatably connected to the main gluing wheel through a bearing.

[0019] Preferably, a connecting arm is fixed on one side of the upper movable plate and the lower movable plate, and a secondary glue-applying wheel is installed on the connecting arm through a connecting member. The structure of the secondary glue-applying wheel is the same as that of the main glue-applying wheel, and the glue supply mechanism also supplies glue to the secondary glue-applying wheel at the same time.

[0020] Preferably, the glue supply mechanism includes a glue feeding component and a glue discharging component;

[0021] The glue feeding component includes a connecting cylinder and a diverter frame. The connecting cylinder is connected to one side of the glue tank, and an auger is rotatably connected inside the connecting cylinder via a bearing. One end of the auger extends into the interior of the glue tank, and the central shaft of the auger extends to the outside of the connecting cylinder. A shaft seal is provided between the central shaft of the auger and the connecting cylinder. The diverter frame is connected to the bottom of the connecting cylinder.

[0022] Preferably, the interior of the glue tank is provided with a cylindrical groove located outside the auger.

[0023] Preferably, the dispensing component includes a guide tube, which is fixed to one side of the fixed plate. A guide frame is connected to the bottom of the guide tube, and a connecting pipe is connected to one side of the guide tube. A flexible hose is connected between the connecting pipe and the diverting frame. A transmission rod is connected to the central shaft of the nonwoven roller. The transmission rod passes through the support frame, and the transmission rod is driven to the central shaft of the auger via a synchronous belt and a synchronous pulley.

[0024] Preferably, the bottom two sides of the guide frame are fixed with pressure plates in an arc shape, and the connecting pipe is fixed with three support plates in a ring shape on the side away from the fixed plate. The end of the support plate is equipped with a support roller, which is in contact with the inner wall of the main glue applicator. The end of the main glue applicator is connected to a sealing plate by a thread on the side away from the fixed plate.

[0025] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0026] The limiting frame can be used to limit the two sides of the foam to ensure the accuracy of the application position when applying glue to the foam later. By utilizing the characteristics of the X-shaped frame and in conjunction with the connecting arm and the secondary glue application wheel, three processes can be carried out simultaneously: applying glue to the foam, applying glue to the non-woven fabric and fiberglass wool, and compacting the third non-woven fabric layer-fiberglass layer-foam layer-fiberglass layer-non-woven fabric layer. This greatly improves the efficiency of car roof foam bonding.

[0027] Since the power source for the transmission rod is the nonwoven fabric roller, when the nonwoven fabric roller rotates, it can provide power to the auger through the transmission rod synchronous belt and synchronous pulley, thereby continuously supplying glue to the main coating wheel and the secondary coating wheel. At the same time, when the nonwoven fabric roller stops rotating, the power output for glue supply can be immediately lost, which can avoid excessive waste of glue. Attached Figure Description

[0053] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] This invention provides, for example Figure 1-13 The illustrated automotive headliner foam positioning and bonding device includes:

[0055] Support platform 1, with limiting frames 2 for limiting the conveying of car roof foam fixed on both sides of the top of support platform 1;

[0056] Two support frames 5 are fixed to the top and bottom of the support platform 1 respectively. A non-woven fabric roller 6 is installed on the side of the support frame 5 away from the support platform 1, and a fiberglass cotton roller 7 is installed on the side of the support frame 5 closer to the support platform 1. The non-woven fabric roller 6 and the fiberglass cotton roller 7 are both connected to the support frame 5 by bearing rotation to ensure that the non-woven fabric and the fiberglass cotton can rotate during the traction process.

[0057] The fixing box 4 is fixed to one side of the limiting frame 2. An X-shaped frame 3 is installed inside the fixing box 4. A pressure roller 33 is installed on one side of the X-shaped frame 3 via a bearing. Two main glue-applying wheels 35 for applying glue to the car roof foam are installed on the other side of the X-shaped frame 3 via a connector.

[0058] The glue tank 8 is fixed on one side of the support frame 5. A glue supply mechanism for supplying glue to the main glue application wheel 35 is provided between the glue tank 8 and the main glue application wheel 35.

[0059] Furthermore, rectangular holes are provided at the top and bottom of the limiting frame 2. A lower fixing frame 22 is fixed in the bottom rectangular hole, and an upper fixing frame 23 passes through the top rectangular hole. Limiting rollers 21 are provided on the opposite sides of the lower fixing frame 22 and the upper fixing frame 23. A horizontal plate 25 is fixed to the top of the upper fixing frame 23. Screws 26 are fixed to the top of the limiting frame 2 near its four corners. The screws 26 pass through the horizontal plate 25, and nuts 24 are threadedly connected to the top and bottom of the horizontal plate 25 on the outside of the screws 26. Moving the horizontal plate 25 up or down can adjust the distance between the upper and lower rows of limiting rollers 21, thereby pressing and limiting foam of different thicknesses and reducing the friction of the foam during movement. The horizontal plate 25 can be locked by the screws 26 and nuts 24 to ensure the stability of the foam during movement.

[0060] Furthermore, the X-shaped frame 3 includes an upper movable plate 31 and a lower movable plate 32, which are arranged in an X shape and are rotatably connected by bearings.

[0061] There are two pressure rollers 33. One pressure roller 33 is rotatably connected to the upper movable plate 31 via a bearing, and the other pressure roller 33 is rotatably connected to the lower movable plate 32 via a bearing.

[0062] The fixed box 4 is equipped with an angle adjustment mechanism for adjusting the horizontal opening angle of the X-shaped frame 3, and slots for the movement of the X-shaped frame 3 are provided on both the upper and lower sides of the fixed box 4.

[0063] Furthermore, the angle adjustment mechanism includes a controller 41, a forward and reverse motor 42, and a sliding plate 44. The controller 41 is installed outside the fixed box 4, the forward and reverse motor 42 is fixed inside the fixed box 4, and a lead screw 43 is installed on the drive shaft of the forward and reverse motor 42. The sliding plate 44 is slidably connected inside the fixed box 4 via a slide rail, and the lead screw 43 is threadedly connected to the sliding plate 44.

[0064] Both the upper movable plate 31 and the lower movable plate 32 have sliding blocks 46 slidably connected to each other via sliding grooves on one side inside the fixed box 4. A connecting rod 45 is provided between the sliding block 46 and the sliding plate 44. The connecting rod 45 is rotatably connected to the sliding block 46 and the sliding plate 44 via bearings.

[0065] Furthermore, one of the main glue-applying wheels 35 is fixed to the upper movable plate 31 by a connector, and the other main glue-applying wheel 35 is fixed to the lower movable plate 32 by a connector.

[0066] The outer wall of the main coating roller 35 is provided with a through hole 36 for dispensing glue;

[0067] The connector includes a connecting post 37, one end of which is fixedly connected to the X-shaped frame 3. A fixing plate 38 is fixed to one side of the connecting post 37 relative to the X-shaped frame 3. The fixing plate 38 is rotatably connected to the main gluing wheel 35 through a bearing.

[0068] Specifically, a connecting arm 34 is fixed on one side of the upper movable plate 31 and the lower movable plate 32 respectively. A secondary glue-applying wheel 39 is installed on the connecting arm 34 through a connecting piece. The structure of the secondary glue-applying wheel 39 is the same as that of the main glue-applying wheel 35, and the glue supply mechanism also supplies glue to the secondary glue-applying wheel 39 at the same time.

[0069] Specifically, the glue supply mechanism includes a glue feeding component and a glue discharging component;

[0070] The glue delivery component includes a connecting cylinder 81 and a diverter frame 82. The connecting cylinder 81 is connected to one side of the glue tank 8, and an auger 85 is rotatably connected inside the connecting cylinder 81 via a bearing. One end of the auger 85 extends into the interior of the glue tank 8, and the central shaft of the auger 85 extends to the outside of the connecting cylinder 81. A shaft seal is provided between the central shaft of the auger 85 and the connecting cylinder 81. The diverter frame 82 is connected to the bottom of the connecting cylinder 81.

[0071] Specifically, the interior of the glue tank 8 is provided with a cylindrical groove 84 located outside the auger 85.

[0072] Specifically, the glue dispensing component includes a guide pipe 9, which is fixed to one side of the fixed plate 38. A guide frame 96 is connected to the bottom of the guide pipe 9, and a connecting pipe 93 is connected to one side of the guide pipe 9. A flexible hose 83 is connected between the connecting pipe 93 and the diverter frame 82. A transmission rod 10 is connected to the central shaft of the nonwoven roller 6. The transmission rod 10 passes through the support frame 5. The transmission rod 10 and the central shaft of the auger 85 are driven by a synchronous belt and a synchronous belt pulley. The power of the nonwoven roller 6 is used to rotate the auger 85, thereby supplying glue to the main glue-applying roller 35 and the secondary glue-applying roller 39. The advantage of this is that when the "car roof" stops molding, the power output for glue supply is immediately lost, avoiding excessive waste of glue.

[0073] Specifically, the bottom two sides of the guide frame 96 are fixed with arc-shaped pressure plates 92. The connecting pipe 93 is fixed with three support plates 91 in a ring shape on the side away from the fixed plate 38. The end of the support plate 91 is equipped with a support roller 95. The support roller 95 is in contact with the inner wall of the main glue applicator 35. The end of the main glue applicator 35 away from the fixed plate 38 is connected to a sealing plate 94 by a thread. The support plates 91 and the support roller 95 can support the guide pipe 9 without affecting the rotation of the main glue applicator 35. The sealing plate 94 can seal the port between the two pressure plates 92 (the other end of the port between the two pressure plates 92 is sealed by the main glue applicator 35), thereby ensuring that the glue can stably seep out from the through hole 36 and evenly apply the foam, fiberglass and non-woven fabric.

[0074] The working principle is as follows:

[0075] First, insert the foam used for making the car roof (generally, car roof foam is made of PU material) between the two limiting frames 2. Use the limiting frames 2 to limit the two sides of the foam to ensure the accuracy of the position when applying glue to the foam later.

[0076] Next, install the nonwoven fabric roller 6 and the glass fiber cotton roller 7 on the upper and lower support frames 5 (the installation method of the nonwoven fabric roller 6 and the glass fiber cotton roller 7 is the same as the existing roll material roller installation method, the only difference is that the central shaft of the subsequent nonwoven fabric roller 6 is connected to the transmission rod 10, and the transmission rod 10 and the nonwoven fabric roller 6 can be connected through a small flange).

[0077] After the nonwoven fabric roller 6 and the glass fiber cotton roller 7 are installed, the nonwoven fabric on the nonwoven fabric roller 6 and the glass fiber cotton on the glass fiber cotton roller 7 are combined with the foam. After the combination, the foam, nonwoven fabric and glass fiber cotton will form a nonwoven fabric layer-glass fiber layer-foam layer-glass fiber layer-nonwoven fabric layer from top to bottom. After applying glue between each layer and pressing it with two pressure rollers 33, a preliminary car roof can be formed. (After the preliminary car roof is subjected to hot pressing and cutting processes, the finished car roof can be obtained. This invention only involves the bonding process of the car roof foam with the nonwoven fabric layer and glass fiber layer, and does not involve the hot pressing process and cutting process of the car roof. It will not be described in detail here.)

[0078] When the foam is coated with glue, the controller 41 can drive the forward and reverse motor 42 to rotate the lead screw 43, which in turn drives the sliding plate 44 to move in the direction of the forward and reverse motor 42. At this time, in conjunction with the connecting rod 45 and the sliding block 46, the horizontal opening of the X-shaped frame gradually decreases (that is, the upper movable plate 31 and the lower movable plate 32 begin to gradually approach each other in the horizontal direction). Then, the two main glue-applying wheels 35 will come into contact with the foam.

[0079] As the foam, non-woven fabric, and fiberglass wool are pulled and moved (the initial car roof will be pulled, as shown in the instruction manual),... Figure 1 At the arrow, the direction indicated by the arrow is the traction direction. The traction equipment is conventional technology, generally using two powered and synchronously pressing rollers for traction. The non-woven roller 6 will rotate, thereby driving the transmission rod 10 to rotate. By using the synchronous belt and synchronous pulley between the transmission rod 10 and the central shaft of the auger 85, the auger 85 can be driven to rotate inside the glue tank 8, thereby forcibly sending the glue inside the glue tank 8 into the connecting cylinder 81, the diverting frame 82, the hose 83, and finally into the guide pipe 9 through the connecting pipe 93.

[0080] After the glue enters the inside of the guide tube 9, it will flow out through the guide frame 96. The pressure plate 92 can ensure that the glue can seep out tightly against the through hole 36 on the outer wall of the main glue roller 35, thereby preventing the glue from flowing down along the guide frame 96 due to gravity when applying glue to the main glue roller 35 located below, which greatly improves the stability when applying glue to the bottom of the foam.

[0081] At the same time, through the connecting arm 34 and the secondary gluing wheel 39, the adhesive can be applied to the surfaces that need to be bonded between the non-woven fabric and the fiberglass wool.

[0082] Due to the characteristics of the X-shaped frame 3, when the two main adhesive rollers 35 come into contact with the foam, the two pressure rollers 33 will also simultaneously compress the non-woven fabric layer-glass fiber layer-foam layer-glass fiber layer-non-woven fabric layer, thereby compacting the car roof foam with the non-woven fabric and glass fiber. Since the three processes are carried out simultaneously (first foam adhesive application, second non-woven fabric and glass fiber adhesive application, and third non-woven fabric layer-glass fiber layer-foam layer-glass fiber layer-non-woven fabric layer compaction), the efficiency of car roof foam bonding is greatly improved.

[0083] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
