Description

Technical Field

[0001] The invention relates to the technical field of flocking of sealing parts, in particular to a flocking and gluing device for automobile sealing parts. Background Art

[0002] The automotive seal flocking glue coating device is mainly composed of three parts: glue coating system, flocking system and drying system. The glue coating system evenly coats the glue on the seal surface, the flocking system attaches the flock to the seal coated with glue in a specific way, and the drying system dries the flocked seal to ensure that the flock is firmly adhered to the seal.

[0003] In the flocking process, the existing technology usually adopts roller flocking or spray gun flocking. Roller flocking uses a rotating roller to press the fluff into the surface of the seal coated with glue, while spray gun flocking uses a spray gun to spray the fluff onto the seal. However, it is difficult to ensure the uniform distribution of the fluff on the uneven surface of the workpiece. In the protrusions or depressions, the amount of fluff attached may be too much or too little, resulting in uneven distribution of the fluff on the surface of the seal, affecting the appearance and performance. It is also difficult to accurately control the implantation direction and angle of the fluff, which easily leads to the fluff direction being scattered.

[0004] Although electrostatic flocking technology uses an electrostatic field to make the fluff stand upright and adsorb on the surface of the workpiece coated with glue, in actual operation, the electrostatic force cannot make the fluff rise to the higher parts of the workpiece for the uneven surface of the workpiece. When the workpiece is pressed down to fully contact the fluff, the fluff in the lower part of the workpiece will be collapsed, which can easily make the fluff uneven.

[0005] Therefore, it is necessary to provide a flocking and gluing device for automobile seals to solve the problems raised in the above background technology. Summary of the invention

[0007] The flocking room is provided with lifting chains on both sides, the lifting chains on both sides are driven by a chain drive motor respectively, and a clamping assembly is connected between the lifting chains on both sides;

[0008] The belt transmission assembly comprises two parallel transmission belts, both ends of which are wound around supporting pulleys, a driving pulley is arranged below the supporting pulley, and the transmission belt is wound around the driving pulley;

[0011] The guide screw rod is bounded by the center, and the threads on both sides have opposite rotation directions.

[0012] Furthermore, as a preference, a compression pulley is rotatably connected to the triangular plate, and the compression pulley compresses the bottom of the conveyor belt.

[0013] Further, as a preference, the clamping assembly includes two fixed plates, the two fixed plates are respectively connected to the lifting chains on both sides, a clamping plate is arranged between the two fixed plates, an inner hole is opened in the center of the clamping plate, a plurality of clamping push blocks are distributed around the inner hole, and each of the clamping push blocks is driven by a telescopic cylinder.

[0014] Further, as a preference, the clamping plate is rotatably arranged between two fixed plates, and one of the fixed plates is provided with a clamping plate driving device for driving the clamping plate to rotate.

[0015] Furthermore, as a preference, a first bevel gear set is connected to the sprocket under each lifting chain, the first bevel gear set is connected to a vertical shaft vertically arranged in the flocking room, a second bevel gear set is connected to the vertical shaft, and two of the second bevel gear sets are respectively connected to both ends of the guide screw.

[0016] Further, as a preference, the fleece blowing assembly comprises a fixed cylinder, and a plurality of air nozzles are distributed at the bottom of the fixed cylinder;

[0017] An electrostatic generator is arranged in the fixing cylinder.

[0018] Further, as a preference, an extension sleeve is provided on the outer sliding sleeve of the fixed cylinder.

[0019] Furthermore, preferably, racks are fixed on both sides of the extension sleeve, and each of the racks is provided with a gear meshing therewith.

[0020] Further, as a preference, each of the gears is connected to a gear shaft, and the gear shaft is rotatably arranged in the flocking room;

[0021] The vertical shaft is connected with a third bevel gear set, and two third bevel gear sets are respectively connected to two gear shafts.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, multiple automated components such as an input conveyor belt, a three-axis gluing robot, a flocking room, a belt transmission assembly and a flock blowing assembly are integrated to realize a fully automated process from gluing to flocking. The process is compact and efficient, which not only greatly reduces manual operations, but also significantly improves production efficiency and reduces labor costs. The three-axis gluing robot can accurately control the gluing path and parameters to ensure the uniformity and accuracy of the gluing and avoid fluctuations in the gluing quality caused by human factors.

[0024] In the present invention, the fluff is blown up by air, so that a dynamic, suspended fluff cloud can be formed under the workpiece, so that the fluff can move more freely to various corners of the workpiece surface, including the concave and convex parts that can be touched; and combined with an electrostatic generator, the fluff is charged, thereby enhancing the adsorption force between the fluff and the workpiece, and promoting the uniform and vertical distribution of the fluff on the workpiece surface, because the interaction between the charges tends to make the fluff cover the entire bottom of the workpiece.

[0025] In the present invention, when the clamping assembly clamps the workpiece and rises, the distance between the two conveyor belts increases accordingly. This ensures that the workpiece can completely avoid the position of the conveyor belt during the flipping and flocking process, providing a larger space for the flocking operation; and the extension sleeve rises synchronously with the clamping assembly, but the extension sleeve rises faster. When the clamping assembly rises to a specific height, the extension sleeve also rises to a sufficiently high position, so that the clamping plate can completely cover the top of the extension sleeve, forming a relatively closed space, effectively preventing the fluff blown up in the fixed cylinder from floating around, not only keeping the production environment clean, but also reducing the waste of fluff and potential safety hazards.

DETAILED DESCRIPTION

[0032] See also Figure 1 and Figure 2 In an embodiment of the present invention, a flocking and gluing device for automobile seals includes an input conveyor belt 1, a three-axis gluing robot 2 is arranged above the input conveyor belt 1, a flocking room 3 is arranged at the output end of the input conveyor belt 1, a belt conveyor assembly 4 is arranged in the flocking room 3, the belt conveyor assembly 4 is at the same height as the input conveyor belt 1, and a blowing assembly 5 is arranged below the belt conveyor assembly 4;

[0033] The flocking room 3 is provided with lifting chains 7 on both sides, and the lifting chains 7 on both sides are driven by a chain drive motor 8 respectively, and a clamping assembly 6 is connected between the lifting chains 7 on both sides;

[0034] The belt transmission assembly 4 includes two parallel transmission belts 41, both ends of the transmission belt 41 are wound around a supporting pulley 42, a driving pulley 43 is arranged below the supporting pulley 42, and the transmission belt 41 is wound around the driving pulley 43;

[0035] Both of the driving pulleys 43 are slidingly connected to a square shaft 44 , and the square shaft 44 is driven to rotate by a belt drive device 48 .

[0036] The workpiece placed on the input conveyor belt 1 can be coated with glue at the position where flocking is required by the three-axis glue coating robot 2 and sent to the flocking room 3. In the flocking room 3, the workpiece is conveyed by the belt conveyor component 4 to the top of the blowing component 5, and is clamped and turned by the clamping component 6 so that the glued side faces downward, and the blowing component 5 blows the fluff to the bottom of the workpiece, and the fluff will be fixed at the glue-coated position of the workpiece, thereby completing the flocking.

[0037] In this embodiment, the two support pulleys 42 are rotatably connected to the lead screw 47, and the support pulley 42 and the drive pulley 43 wound by the same transmission belt 41 are both rotatably connected to the triangular plate 46, and the triangular plate 46 is threadedly connected to the lead screw 47;

[0038] The guide screw 47 is defined by the center, and the threads on both sides have opposite rotation directions.

[0039] That is to say, when the guide screw 47 rotates, it can drive the two triangular plates 46 to move closer to or away from each other, so that the distance between the two conveyor belts 41 can change. When the clamping assembly 6 clamps the workpiece, by increasing the distance between the two conveyor belts 41, it can avoid the position above the blowing assembly 5, so that the workpiece can fit with the blowing assembly 5.

[0040] In this embodiment, a pressing pulley 45 is rotatably connected to the triangular plate 46 , and the pressing pulley 45 presses the bottom of the conveying belt 41 to make the conveying belt 41 taut and parallel up and down.

[0041] See also Figure 3 In this embodiment, the clamping assembly 6 includes two fixed plates 61, and the two fixed plates 61 are respectively connected to the lifting chains 7 on both sides. A clamping plate 62 is arranged between the two fixed plates 61. An inner hole 63 is opened in the center of the clamping plate 62, and a plurality of clamping push blocks 64 are distributed around the inner hole 63. Each of the clamping push blocks 64 is driven by a telescopic cylinder.

[0042] When the workpiece moves to the bottom of the clamping plate 62, the inner hole 63 is sleeved outside the workpiece by lowering the lifting chain 7, and the workpiece can be clamped by extending the clamping push block 64 forward.

[0043] In this embodiment, the clamping plate 62 is rotatably disposed between two fixed plates 61 , and a clamping plate driving device 65 for driving the clamping plate 62 to rotate is disposed in one of the fixed plates 61 .

[0044] The workpiece can be turned over by rotating the clamping plate 62 through the clamping plate driving device 65 so that the glue-coated side faces downward.

[0045] See also Figure 4 In this embodiment, a first bevel gear set 72 is connected to the sprocket under each lifting chain 7, and the first bevel gear set 72 is connected to a vertical shaft 71 vertically set in the flocking room 3. A second bevel gear set 73 is connected to the vertical shaft 71, and the two second bevel gear sets 73 are respectively connected to the two ends of the guide screw 47.

[0046] That is to say, when the lifting chain 7 is lifted or lowered, it can drive the guide screw 47 to rotate synchronously, and make the distance between the two conveyor belts 41 increase when the clamping assembly 6 rises. When the clamping assembly 6 rises to a certain height, the distance between the two conveyor belts 41 is the largest. At this time, the conveyor belt 41 completely avoids the position above the blowing assembly 5.

[0047] See also Figure 5In this embodiment, the blowing assembly 5 includes a fixed cylinder 51, and a plurality of air nozzles 52 are distributed at the bottom of the fixed cylinder 51;

[0048] The fixing cylinder 51 is provided with an electrostatic generator.

[0049] The fixed cylinder 51 is filled with fluff, which is charged by an electrostatic generator. When the workpiece is located above the fixed cylinder 51, the fluff is blown upward by the air nozzle 52 so that the fluff is distributed under the workpiece. Since the fluff is charged, the fluff is vertically attached to the bottom of the workpiece and fixed to the glue-coated part of the workpiece, thereby completing the flocking.

[0050] By using air to blow up the fluff, a dynamic, suspended fluff cloud can be formed under the workpiece, allowing the fluff to move more freely to every corner of the workpiece surface, including the unreachable concave and convex parts.

[0051] In this embodiment, an extension sleeve 53 is slidably sleeved on the outer periphery of the fixing tube 51 .

[0052] The extended sleeve 53 can surround the upper part of the fixed tube 51 to prevent the blown fluff from scattering around.

[0053] In this embodiment, racks 54 are fixed on both sides of the extension sleeve 53 , and each rack 54 is provided with a gear 55 meshing therewith.

[0054] The extension sleeve 53 can be driven to rise and fall by the rotation of the gear 55 .

[0055] In this embodiment, each of the gears 55 is connected to a gear shaft 56, and the gear shaft 56 is rotatably disposed in the flocking room 3;

[0056] A third bevel gear set 74 is connected to the vertical shaft 71 , and two third bevel gear sets 74 are connected to two gear shafts 56 , respectively.

[0057] That is to say, when the lifting chain 7 is lifted or lowered, it can drive the extension sleeve 53, so that when the clamping assembly 6 rises, the extension sleeve 53 also rises, and the rising speed of the extension sleeve 53 is faster than the rising speed of the clamping assembly 6. When the clamping assembly 6 rises to a certain height, the clamping plate 62 covers the top of the extension sleeve 53, thereby preventing the fluff blown up in the fixed cylinder 51 from floating around.

[0058] The specific implementation includes the following steps:

[0059] The automotive seal to be flocked is stably placed at the starting position of the input conveyor belt 1. As the input conveyor belt 1 moves, the workpiece is transported to the working area of ​​the three-axis glue coating robot 2;

[0060] The three-axis gluing robot 2 applies glue accurately to the designated part of the workpiece according to the preset gluing path and parameters. After the gluing is completed, the workpiece continues to be transported forward and enters the flocking room 3;

[0061] The workpiece is transferred to the belt conveyor assembly 4 and continues to move. When the workpiece reaches the designated position of the belt conveyor assembly 4, the lifting chains 7 on both sides are driven down by the chain drive motor 8, and the inner hole 63 of the clamping plate 62 of the clamping assembly 6 is sleeved on the outside of the workpiece. Subsequently, the clamping push block 64 is driven forward by the telescopic cylinder to clamp the workpiece.

[0062] The lifting chain 7 drives the clamping assembly 6 and the workpiece to rise, and at the same time the clamping plate driving device 65 is started to rotate the clamping plate 62 180 degrees, turning the workpiece over so that the glue-coated surface faces downward;

[0063] When the clamping assembly 6 rises and turns over, the distance between the two conveyor belts 41 increases, and the extension sleeve 53 rises. When the clamping assembly 6 rises to a certain height, the distance between the two conveyor belts 41 is the maximum, and the extension sleeve 53 rises to the top of the clamping plate 62 covering the extension sleeve 53.

[0064] The electrostatic generator charges the fluff in the fixed cylinder 51, and the air nozzle 52 blows the fluff upward and evenly distributes it under the workpiece. Since the fluff is charged, the fluff will vertically adhere to the part of the workpiece where the glue is applied, completing the flocking process;

[0065] The lifting chain 7 descends to the position where the workpiece is placed back on the belt conveyor assembly 4, and the clamping assembly 6 releases the clamping push block 64 to release the workpiece. At this time, the workpiece is moved out of the flocking room 3 through the belt conveyor assembly 4 to prepare for the next process.

[0066] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
