Description

Technical Field

[0001] This utility model belongs to the field of automotive rubber strip processing technology, specifically a glue coating device and intelligent glue coating equipment for automotive rubber strips. Background Technology

[0002] The adhesive backing of automotive rubber strips refers to a thin layer of adhesive material covering the surface of the sealing strip (usually EPDM rubber), whose core function is to enhance the durability and functionality of the sealing strip.

[0003] The film covering the adhesive backing surface of the adhesive strip is professionally called release liner or anti-stick film. Its core function is to isolate and protect the adhesive backing layer, ensure that the adhesion is not damaged, and simplify the construction process.

[0004] In existing technologies, when using intelligent machinery to apply adhesive backing to the surface of adhesive strips, the process typically involves first applying adhesive, followed by a film coating on the adhesive layer. The reel in the intelligent machinery that holds the anti-adhesive film is usually fixed to a rotating shaft with screws. However, during replacement, the screw installation presents the following problems: First, screw stripping is a problem, and multiple screws are generally required for fixation, making operation inconvenient and prone to loss. Second, each time the reel is replaced, it needs to be manually removed and then lifted for placement. Since each replacement typically involves a temporary machine stoppage, this significantly wastes work efficiency, and the pressure of time during replacement increases the risk of the reel slipping when lifted.

[0007] Preferably, the blocking member includes a first groove; a pair of symmetrically distributed first grooves are provided on the outer wall of the first fixed post; and a blocking block is fixed to the bottom of the first groove by a spring.

[0008] Preferably, the blocking block has a first inclined surface on the side wall near the rotating column.

[0009] Preferably, the positioning element includes a second groove; a second groove is provided on the end of the rotating column; a bidirectional lead screw is rotatably connected to the bottom of the second groove; a pair of symmetrically distributed annular plates are connected to the bidirectional lead screw through a lead screw nut pair; a pair of symmetrically distributed first through slots are provided on the inner wall of the second groove; a clamping element is provided on the annular plate, and the clamping element limits the coil placed on the rotating column; the bidirectional lead screw is positioned by a positioning unit.

[0010] Preferably, the clamping component includes a fixing block and a lifting block; a pair of symmetrically distributed fixing blocks are fixedly connected to the outer wall of the annular plate; the fixing blocks are slidably connected in the first through groove; a third groove is provided at the top of the fixing block; and a lifting block is fixedly connected to the bottom of the third groove by a spring.

[0011] Preferably, a pair of symmetrically distributed first inclined grooves are provided in the first through groove; first sliding columns are rotatably connected to both sides of the lifting block; the first sliding columns are slidably connected in the first inclined grooves.

[0012] Preferably, the positioning unit includes: a square groove on the end of the bidirectional lead screw, and the cross-section of the square groove is T-shaped; a square plate is fixed to the bottom of the square groove by a spring; a square post is fixed to the end of the square plate, and the square post extends out of the bidirectional lead screw and is fixed to a second fixing post; a handle is fixed to the second fixing post.

[0013] Preferably, a pair of symmetrically distributed positioning posts are fixed to the handle; a positioning hole is provided on the end of the rotating post at a position relative to the positioning posts.

[0014] Secondly, this utility model provides an intelligent adhesive application device for automotive rubber strips, which consists of any of the above-mentioned adhesive application devices for automotive rubber strips and an industrial robot connected to it.

[0015] In a preferred embodiment, the industrial robot is a six-axis articulated robot.

[0016] The advantages of this utility model, which differ from existing technologies, are as follows:

[0017] 1. The adhesive applicator for automotive rubber strips described in this utility model, during initial operation (i.e., during downtime, off-duty hours, or on-duty hours), firstly, the first sliders of multiple reels pass through the first slide groove and enter the second slide groove. Then, the multiple reels are placed on the first fixed post by the blocking member. Next, the first slider of a single reel enters the first slide groove and is fixed by the positioning member. The installation of the reels does not require screws, which is simple and convenient and prevents loss. At the same time, since multiple reels are placed on the first fixed post, after a reel is used up, it is detached from the rotating post. At this time, the used reel is relatively light and easy to detach. Then, the unused reel is slid into the rotating post through the first fixed post without manual lifting. This also avoids the situation where the heavier unused reel detaches due to a quick replacement.

[0018] 2. The adhesive applicator for automotive rubber strips described in this utility model places the required roll of material onto a rotating column, and then rotates it via a bidirectional screw. The rotation of the bidirectional screw causes a pair of annular plates to move towards each other, which in turn causes the fixed blocks to move towards each other, allowing the first sliding post of the lifting block to move within the first inclined groove. This causes the lifting block to move upward and extend beyond the first through groove, clamping the roll of material through the pair of lifting blocks. Simultaneously, during subsequent disassembly, the bidirectional screw is rotated in the opposite direction, causing the pair of annular plates and the fixed blocks to move in the same direction, allowing the lifting block to move downward and completely sink into the first through groove, without affecting the roll replacement operation.

[0019] 3. The adhesive application device for automotive rubber strips described in this utility model, when used in conjunction with an industrial robot to form an intelligent adhesive application system, can fully utilize the industrial robot's control system to achieve fully automated intelligent operation of applying primer, drying, and applying adhesive. Only manual assistance is required to place the material into the fixture and activate the vacuum adsorption switch to fix the material. This greatly improves production efficiency, saves manpower, and reduces losses caused by human error. Attached Figure Description

[0039] like Figures 1 to 6As shown, this utility model discloses an adhesive applicator for automotive rubber strips, comprising a support plate 1 and a connecting column 11; the connecting column 11 is fixedly connected to the middle of the top of the support plate 1; a pair of L-shaped plates 12 symmetrically distributed about the connecting column 11 are fixedly connected to the top of the support plate 1; a pair of symmetrically distributed feeding parts 14 are provided on one side wall of the support plate 1; a first fixing column 15 is fixedly connected to the L-shaped plate 12; a rotating column 16 is rotatably connected to the end of the first fixing column 15; a reel 13 is placed on the rotating column 16 through a positioning member; a set of reels 13 is placed on the first fixing column 15, and the reels 13 are prevented from detaching by a blocking member; a second sliding groove 19 is provided on the first fixing column 15; a first sliding groove 17 is provided on the rotating column 16; a first slider 18 is fixedly connected to the inner wall of the reel 13; the reel 13 is annular; the first slider 18 slides in the first sliding groove 17 or the second sliding groove 19; the opening cross-sections of the first sliding groove 17 and the second sliding groove 19 are the same. In existing technologies, when using intelligent machinery to apply adhesive backing to the surface of adhesive strips, a primer is typically applied first, followed by a film coating on the adhesive layer. The reel 13 holding the anti-adhesive film in the intelligent machinery is usually fixed to the rotating shaft with screws. However, during replacement, the screw installation presents several problems: First, the screws are prone to stripping, and multiple screws are typically required for fixation, making operation inconvenient and prone to loss. Second, each replacement of the reel 13 requires manual removal and lifting, which, due to the temporary machine stoppage, significantly wastes work efficiency. Furthermore, the urgency of the replacement time increases the risk of slippage when lifting the reel 13. Therefore, this invention addresses this issue by first moving the first slider 18 of multiple reels 13 through the first slide groove 17 into the second slide groove 19 during initial operation (i.e., during breaks, at the end of the workday, or at the start of the workday). 3. The device is placed on the first fixed post 15 by the blocking component. Then, the first slider 18 of the single reel 13 enters the first slide groove 17 and is fixed by the positioning component. The installation of the reel 13 does not require screw fixing, which is simple and convenient and prevents loss. At the same time, multiple reels 13 are placed on the first fixed post 15. After a reel 13 is used up, it is detached from the rotating post 16. At this time, the used reel 13 is relatively light and easy to detach. Then, the unused reel 13 is slid into the rotating post 16 through the first fixed post 15 without manual lifting. At the same time, it avoids the situation where the heavier unused reel 13 detaches due to the urgent replacement. The unloading component 14 is the existing technology, which is to perform the coating operation through the anti-stick film in the reel 13. No innovative operation is performed on the unloading component 14. Therefore, the unloading component 14 will not be described in detail. The connecting post 11 is connected to the robot by common connecting components such as several sets of screws-nuts or flanges.

[0040] The barrier includes a first groove 2; a pair of symmetrically distributed first grooves 2 are provided on the outer side wall of the first fixing post 15; a barrier block 21 is fixed to the bottom of the first groove 2 by a spring;

[0041] The first inclined surface 22 is provided on the side wall of the blocking block 21 near the rotating column 16;

[0042] During operation, the first inclined surface 22 allows the reel 13 to be directly pushed onto the first fixed post 15. The reel 13 is then blocked by the blocking block 21, preventing unused reels 13 from affecting reels 13 in use during later operations.

[0043] The positioning component includes a second groove 3; a second groove 3 is provided on the end of the rotating column 16; a bidirectional lead screw 31 is rotatably connected to the bottom of the second groove 3; a pair of symmetrically distributed annular plates 32 are connected to the bidirectional lead screw 31 through a lead screw nut pair; a pair of symmetrically distributed first through slots 33 are provided on the inner wall of the second groove 3; a clamping component is provided on the annular plate 32, and the clamping component limits the winding reel 13 placed on the rotating column 16; the bidirectional lead screw 31 is positioned by a positioning unit.

[0044] The clamping component includes a fixing block 34 and a lifting block 36; a pair of symmetrically distributed fixing blocks 34 are fixedly connected to the outer wall of the annular plate 32; the fixing blocks 34 are slidably connected in the first through groove 33; a third groove 35 is opened at the top of the fixing block 34; the lifting block 36 is fixedly connected to the bottom of the third groove 35 by a spring;

[0045] A pair of symmetrically distributed first inclined grooves 37 are provided in the first through groove 33; first sliding columns 38 are rotatably connected to both sides of the lifting block 36; the first sliding columns 38 are slidably connected in the first inclined grooves 37.

[0046] During operation, the required reel 13 is placed on the rotating column 16, and then rotated by the bidirectional screw 31. The rotation of the bidirectional screw 31 will drive a pair of annular plates 32 to move towards each other, thereby causing the fixed blocks 34 to move towards each other, and causing the first sliding column 38 of the lifting block 36 to move in the first inclined groove 37, so that the lifting block 36 moves upward and extends out of the first through groove 33. The pair of lifting blocks 36 clamp the reel 13. At the same time, when disassembling later, the bidirectional screw 31 is rotated in the opposite direction, so that the pair of annular plates 32 and the fixed blocks 34 move in the same direction, and the lifting block 36 moves downward and sinks completely into the first through groove 33, without affecting the replacement operation of the reel 13.

[0047] The positioning unit includes: a square groove 4 on the end of the bidirectional lead screw 31, and the cross section of the square groove 4 is T-shaped; a square plate 42 is fixed to the bottom of the square groove 4 by a spring; a square post 41 is fixed to the end of the square plate 42, and the square post 41 extends out of the bidirectional lead screw 31 and is fixed to a second fixed post 43; a handle 44 is fixed to the second fixed post 43.

[0048] A pair of symmetrically distributed positioning pins 46 are fixed to the handle 44; a positioning hole 45 is provided on the end of the rotating pin 16 at a position relative to the positioning pins 46;

[0049] During operation, the coil 13 is clamped by a pair of lifting blocks 36. Then, the handle 44 is released, and the handle 44, the second fixing post 43, the square post 41 and the square plate 42 are pulled back by the spring, so that the positioning post 46 is inserted into the positioning hole 45, thus completing the fixation of the bidirectional lead screw 31. The same procedure is followed when replacing it.

[0050] Working principle: During initial operation, i.e., during downtime, off-duty hours, or on-duty hours, the first slider 18 of multiple reels 13 is first moved through the first slide groove 17 into the second slide groove 19. Then, the multiple reels 13 are placed on the first fixed post 15 by the blocking member. Next, the first slider 18 of a single reel 13 enters the first slide groove 17 and is fixed by the positioning member. The installation of the reels 13 does not require screws, making it simple, convenient, and preventing loss. Furthermore, multiple reels 13 can be placed... On the first fixed post 15, after a coil 13 is used up, it is detached from the rotating post 16. At this time, the used coil 13 is relatively light and easy to detach. Then, the unused coil 13 is slid into the rotating post 16 through the first fixed post 15 without manual lifting. This also avoids the situation where the heavier unused coil 13 may detach due to a quick replacement. The first inclined surface 22 can push the coil 13 directly into the first fixed post 15, where it is then blocked by the blocking block 21 to prevent it from detaching later. During operation, unused reels 13 do not affect reels 13 in use. The reel 13 to be used is placed on the rotating column 16, and then rotated by the bidirectional lead screw 31. The rotation of the bidirectional lead screw 31 causes a pair of annular plates 32 to move towards each other, which in turn causes the fixed blocks 34 to move towards each other. This causes the first sliding post 38 of the lifting block 36 to move within the first inclined groove 37, allowing the lifting block 36 to move upwards and extend beyond the first through groove 33. The pair of lifting blocks 36 clamp the reel 13, and simultaneously facilitates subsequent disassembly. Rotate the bidirectional lead screw 31 in the reverse direction to move the pair of annular plates 32 and the fixing block 34, causing the lifting block 36 to move down and sink completely into the first through groove 33. This will not affect the replacement operation of the coil 13. After the coil 13 is clamped by the pair of lifting blocks 36, release the handle 44. The handle 44, the second fixing post 43, the square post 41 and the square plate 42 will be pulled back by the spring, allowing the positioning post 46 to be inserted into the positioning hole 45, thus completing the fixing of the bidirectional lead screw 31. The same procedure will be followed when replacing it in the future.

[0051] Please see Figure 7 and Figure 8In more intelligent application scenarios, the automotive adhesive strip coating device of this utility model can be fixedly connected to an existing industrial robot to form an intelligent automotive adhesive strip coating equipment to perform production operation steps. Specifically, the automotive adhesive strip coating device of this application can be fixedly connected to the industrial robot 5 using flange 51. The industrial robot 5 is more preferably a six-axis articulated robot, such as, but not limited to, the Hikvision HAR8-2010 vertical multi-joint robot.

These settings are primarily designed to automate the primer application, drying, and adhesive application processes using industrial robots via pre-programmed control procedures, enabling fully automated and intelligent adhesive application for automotive rubber strips. Therefore, existing industrial robot models can meet these requirements. Of course, parameters such as maximum working radius, rated load, repeatability, noise level, and operating temperature are all selectable indicators based on actual needs.

[0052] This utility model provides an intelligent adhesive coating device for automotive rubber strips. During operation, the rubber strip material is manually placed into a dual-station material fixing fixture 53. A vacuum adsorption switch is activated to fix the material. The fixture has upper and lower layers for placing the material, automatically fixing and clamping it. An industrial robot servo control module 52 controls its forward, backward, and vertical movement.

Precision base coat, baking, and adhesive application modules are all controlled by precision modules and servo motors. After the material is placed, the industrial robot switch is activated. First, the first layer of material slides into the robotic arm's travel range. The robotic arm applies the base coat along the material's shape. After base coat application, the material is dried. After drying, a blue inspection is performed to ensure there are no problems before adhesive application. Finally, the adhesive is pressed against the application area. The above machine is a frame model, debugged via a human-machine interface, and its movement is automatically controlled by a PLC.
