Description

Technical Field

[0001] This utility model relates to the technical field of shoe glue application equipment, and more specifically, to an angle-adjustable floating mechanism for glue application equipment. Background Technology

[0002] In the automated glue application process of shoe manufacturing, industrial robots from companies like FANUC have widely incorporated 3D camera scanning technology. This technology generates over 240 precise glue application points on the shoe upper / sole through modeling, enabling trajectory-based glue application. The floating mechanism, as a core protective component, primarily blocks excess glue from the brush (preventing it from flowing to non-adhesive areas of the shoe upper) and avoids hard collisions between the mechanism and the shoe upper that could trigger an emergency stop for the robot. However, the floating mechanisms of existing glue application equipment exhibit several technical shortcomings when adapting to complex shoe upper contours and meeting the high-precision operation requirements of robots: Firstly, the rigidity of the stop material results in a lack of adaptive angle capability. Existing floating mechanisms often use rigid materials such as metal or hard plastic for their stops (e.g., the floating mechanism disclosed in prior art document CN107598530B uses rigid resin materials for its stops). While these materials provide basic glue protection, the shoe upper contour (especially the arch and toe corners) is often curved. When the robot moves along a point, the rigid stop cannot adaptively adjust its posture according to changes in the shoe upper angle, easily generating significant contact resistance. When the resistance exceeds the robot's preset threshold, it directly triggers an emergency stop, interrupting the glue application process. Furthermore, the rigid contact can cause indentations and wear on the shoe upper, significantly increasing the defect rate. Secondly, the position and angle of the stop blocks are not adjustable, resulting in poor adaptability. Existing floating mechanisms often have stop blocks directly fixed to the cylinder output shaft or mounting base with bolts, lacking an adjustment mechanism. In shoe production, different sizes and styles (such as athletic shoes and leather shoes) need to be addressed, with significant differences in curvature and width. Fixed stop blocks cannot adjust their position and angle according to shoe type, leading to either incomplete glue application (overflowing glue and contaminating the shoe surface) due to excessive distance from the shoe surface, or increased collision risk due to excessive proximity. This significantly increases the cost of adapting the equipment to multiple shoe types. Utility Model Content

[0003] The purpose of this invention is to provide an angle-adjustable floating mechanism for adhesive application equipment, so as to solve the problem of the non-adjustable position and angle of the stop block and poor adaptability mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides an angle-adjustable floating mechanism for an adhesive application device, including a floating component. The floating component is installed at the bottom of a main body plate, on which a brush spindle is mounted. A brush is mounted at the end of the brush spindle. The floating component includes a cylinder, and a mounting positioning block is mounted on the output shaft of the cylinder. A stop block is mounted on the mounting positioning block to prevent adhesive from flowing to the shoe upper. The cylinder can drive the stop block to move in the front-back direction. The stop block is tilted and made of flexible material, which can adaptively adjust its angle according to the angle of the shoe upper to reduce the contact resistance between the main body of the mechanism and the shoe upper, and prevent the robot from triggering an emergency stop due to excessive resistance.

[0005] This setup involves installing a floating component at the bottom of the main body plate, with a brush attached to the end of the brush spindle on the main body plate (providing an object for the adhesive blocking). A cylinder serves as the power source, with its output shaft connected to a positioning block. The positioning block transmits the cylinder's power to the stop block. The stop block is tilted (preset to adapt to the initial angle of the shoe's curvature) and made of flexible material. Its core function is to physically block excess adhesive from the brush (preventing it from flowing onto the shoe's surface), while also possessing deformation capabilities. The cylinder can drive the stop block to move back and forth (adjusting the distance to the shoe's surface). When the robot moves the mechanism along points on the shoe's surface, the flexible stop block can deform according to the curvature angle of the shoe arch and toe, adaptively adjusting its posture to reduce contact resistance with the shoe's surface.

[0006] Preferably, a motor is mounted on the upper part of the main body plate, and the output shaft of the motor drives the brush spindle to rotate through a transmission wheel.

[0007] The power source installation for this setting is as follows: the motor is fixed to the upper part of the main body plate (separated from the bottom floating component); the power transmission path is as follows: the motor output shaft is connected to the transmission wheel, and the meshing / friction transmission of the transmission wheel (such as synchronous belt pulley, gear) drives the brush spindle to rotate, which in turn makes the brush at the end of the spindle rotate synchronously to realize the glue application action.

[0008] Preferably, the end of the brush spindle away from the brush is connected to a dispensing valve via a rotary joint and a hose, and the dispensing valve is connected to a glue tank via a pipeline.

[0009] This setup involves supplying glue from the glue tank to the dispensing valve via a pipeline. The dispensing valve controls the flow of glue (adjusting the output as needed). The end of the brush spindle furthest from the brush is connected to the dispensing valve via a rotary joint and a glue tube. Glue flows into the spindle through the rotary joint (or directly to the brush). The coordination logic with the floating mechanism is as follows: the rotary joint ensures that glue delivery does not interfere with the spindle rotation, the dispensing valve precisely controls the glue to reduce excess glue, and the stop block is relieved of its glue-blocking burden.

[0010] Preferably, the top of the cylinder is fixed to the main body plate by a bearing cover, and the end of the brush spindle passes through the bearing cover, which covers the bearing of the brush spindle.

[0011] In this configuration, the top of the cylinder is connected to the main body plate via a bearing cover, which provides a rigid base for fixing the cylinder. The end of the brush spindle passes through the bearing cover, which completely covers the bearing part of the spindle (blocking external impurities).

[0012] Preferably, an adjusting plate is installed at one end of the stop block, and a strip hole is provided on the adjusting plate. The mounting positioning block is connected to the adjusting plate by bolts. The position of the adjusting plate is adjusted by sliding cooperation between the strip hole and the bolts, and is locked and fixed by nuts.

[0013] This setting includes an adjusting plate at one end of the stop block with a slotted hole; the mounting positioning block is connected to the adjusting plate by bolts passing through the slotted hole; after loosening the nut, the adjusting plate can slide along the slotted hole (to achieve fine adjustment of the stop block's front-to-back / left-to-right position); after adjustment, tighten the nut to fix the position by the friction between the bolt and the slotted hole.

[0014] Preferably, the flexible material is an elastic plastic or nitrile rubber.

[0015] This feature uses either elastic plastic or nitrile rubber. Elastic plastic has good deformation recovery (it does not permanently deform after repeated self-adaptation), while nitrile rubber combines elasticity with resistance to adhesive corrosion (it can withstand polyurethane and neoprene adhesives commonly used in shoemaking). Both materials are suitable for the normal temperature and humidity environment of shoemaking workshops, are odorless, not easy to age, and can maintain flexibility for a long time.

[0016] Preferably, side baffles for external protection of the brush sides are installed on both sides of the block.

[0017] This device features side baffles installed on both sides of the baffle block, extending to the outside of the brush side (without contacting the brush bristles); its core function is to prevent glue from splashing from the side when the brush rotates at high speed; the side baffles move synchronously with the baffle block (including front and rear adjustment and angle self-adaptation), always covering the side of the brush, forming a comprehensive system of "front glue blocking + side protection".

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: In this adjustable floating mechanism for the glue-applying equipment, the stop is made of elastic plastic / nitrile rubber (flexible material) and is tilted. It can adaptively adjust its angle according to the arch and toe of the shoe, greatly reducing the contact resistance with the shoe surface and avoiding the robot from stopping suddenly due to excessive resistance, thus ensuring continuous glue application. The flexible material also cushions the contact force between the stop and the shoe surface, eliminating the indentations and wear caused by existing rigid stops and reducing the defect rate. The cylinder drives the stop block to move back and forth, adjusting the distance between it and the shoe upper according to the glue application point, preventing glue overflow from being too far away and collision from being too close. The stop block can be finely adjusted forward / backward and left / right through the slotted holes of the adjustment plate, adapting to different shoe sizes (e.g., 35-44) and styles (sports shoes / dress shoes) without replacing the stop block, solving the high adaptation cost problem of "one shoe, one mechanism". After adjustment, it is locked with a nut, balancing flexibility and stability. The stop block's front blocking glue and the side baffles on both sides prevent side splashing, forming "all-round protection" to prevent glue from contaminating the shoe upper edges and upper. The bearing cover covers the brush main shaft bearing, blocking glue and dust corrosion and extending bearing life. At the same time, the bearing cover reinforces the cylinder installation, preventing the cylinder from loosening and tilting, maintaining glue application accuracy, and reducing equipment maintenance frequency and cost.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an angle-adjustable floating mechanism for adhesive application equipment, such as... Figure 1 , Figure 2 , Figure 3As shown, the system includes a floating component 4, which is installed at the bottom of the main body plate 7. A brush spindle 6 is mounted on the main body plate 7, and a brush is mounted at the end of the brush spindle 6. The floating component 4 includes a cylinder 42, and a mounting positioning block 43 is mounted on the output shaft of the cylinder 42. A stop block 44 is mounted on the mounting positioning block 43. The stop block 44 is used to block glue from flowing to the shoe upper. The cylinder 42 can drive the stop block 44 to move in the front-back direction. The stop block 44 is tilted and made of flexible material, which can adaptively adjust its angle according to the angle of the shoe upper to reduce the contact resistance between the main body of the mechanism and the shoe upper, and prevent the robot from triggering an emergency stop due to excessive resistance.

[0022] Component installation and power transmission: The floating component 4 is installed at the bottom of the main body plate 7. The brush spindle 6 on the main body plate 7 is equipped with a brush (providing an object for the glue blocking); the cylinder 42 is the power source, and the output shaft is connected to the mounting positioning block 43. The positioning block transmits the power of the cylinder to the stop block 44; the core characteristics of the stop block: the stop block 44 is tilted (preset to adapt to the initial angle of the shoe upper arc) and is made of flexible material; its core function is to physically block excess glue on the brush (preventing it from flowing to the shoe upper), and it also has the ability to deform; adaptive and anti-sudden stop mechanism: the cylinder 42 can drive the stop block 44 to move back and forth (adjusting the distance with the shoe upper). When the robot drives the mechanism to move along the shoe upper points, the flexible stop block can deform with the arc angle of the shoe arch and toe, adaptively adjusting its own posture and reducing the contact resistance with the shoe upper. Addressing the pain point of robot emergency stops: Compared to existing rigid blocks (such as the rigid resin blocks in comparison document CN107598530B), the deformation capability of flexible blocks can significantly reduce contact resistance, preventing the resistance from exceeding the robot's threshold and triggering an emergency stop, thus ensuring continuous glue application; Dual protection for the shoe upper: Flexible materials cushion contact force, eliminating shoe upper indentations and wear caused by rigid blocks; Tilt setting and fore-and-aft adjustment functions allow for precise fit to the shoe upper, avoiding glue overflow pollution caused by incomplete glue application; Adaptable to curved shoe uppers: The adaptive angle design eliminates the need for separate adjustments to mechanisms for different curved shoe uppers, directly adapting to complex contours such as shoe arches and toe corners, simplifying the operation process.

[0023] In this embodiment, as Figure 3 As shown, a motor 2 is installed on the upper part of the main body plate 7, and the output shaft of the motor 2 drives the brush main shaft 6 to rotate through the transmission wheel 3.

[0024] Power source installation: Motor 2 is fixed to the upper part of the main body plate 7 (space-separated from the bottom floating component 4); Power transmission path: The output shaft of motor 2 is connected to the transmission wheel 3. Through the meshing / friction transmission of the transmission wheel (such as synchronous belt pulley, gear), the brush spindle 6 is driven to rotate, which ultimately makes the brush at the end of the spindle rotate synchronously to realize the glue application action. Motor 2 drives the brush spindle 6 to rotate stably via transmission wheel 3, avoiding localized increases in glue overflow caused by brush speed fluctuations—reducing excess glue production and indirectly lowering the glue-blocking pressure of stop 44, thus improving the glue-blocking effect; Motor 2 and floating component 4 are installed separately, and when transmission wheel 3 drives the brush spindle 6 to rotate, it will not collide or jam with the extension and retraction of cylinder 42 or the angle adjustment of stop 44, ensuring that the floating mechanism works independently and smoothly.

[0025] Specifically, such as Figure 3 As shown, the end of the brush spindle 6 away from the brush is connected to a dispensing valve 1 via a rotary joint 5 and a glue tube. The dispensing valve 1 is connected to a glue tank 8 via a pipeline.

[0026] The glue tank 8 supplies glue to the dispensing valve 1 through a pipeline. The dispensing valve 1 controls the flow of glue (adjusting the output as needed). The end of the brush spindle 6 furthest from the brush is connected to the dispensing valve 1 through a rotary joint 5 and a glue tube. Glue flows into the spindle through the rotary joint 5 (or directly into the brush). The rotary joint 5 ensures that the glue delivery does not interfere with the rotation of the brush spindle 6. The dispensing valve 1 precisely controls the glue to reduce excess glue, thus reducing the glue-blocking burden on the stop block 44. The dispensing valve 1 precisely controls the glue supply to avoid excessive glue application, while the rotary joint 5 ensures stable glue delivery to prevent glue interruption or leakage. Together, they reduce excess glue on the brush, allowing the stop block 44 to block only a small amount of residual glue, thus extending the stop block's lifespan. The rotary joint 5 can adjust its angle according to the brush spindle 6 or the robot's movements, and synchronously adapts to the multi-directional glue application points with the adaptive stop block 44 of the floating mechanism, avoiding localized glue overflow caused by glue delivery deviation and improving the overall glue application quality.

[0027] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the top of the cylinder 42 is fixed to the main body plate 7 by the bearing cover 41, and the end of the brush spindle 6 passes through the bearing cover 41, which covers the bearing of the brush spindle 6.

[0028] Cylinder fixing: The top of cylinder 42 is connected to the main body plate 7 through bearing cover 41, which provides a rigid fixing base for the cylinder; Bearing protection: The end of brush spindle 6 passes through bearing cover 41, which completely covers the bearing part of brush spindle 6 (blocking external impurities). The bearing cover 41 prevents glue drips and dust from entering the bearing during application, thus avoiding bearing wear and jamming, solving the problem of easy damage to existing exposed bearings, and extending the component replacement cycle. Compared with the existing simple bracket fixation, the bearing cover 41 is more rigid and can withstand the impact of long-term high-frequency extension and retraction of the cylinder 42, preventing the position of the stop block 44 from shifting due to cylinder loosening or tilting, and maintaining glue blocking accuracy. The bearing cover simultaneously achieves "fixing the cylinder + protecting the bearing", eliminating the need for additional brackets or protective covers, reducing the number of components and lowering the complexity of the equipment.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, an adjusting plate 442 is installed at one end of the stop block 44. The adjusting plate 442 has a strip hole 443. The mounting positioning block 43 is connected to the adjusting plate 442 by bolts. The position of the adjusting plate 442 is adjusted by sliding fit between the strip hole 443 and the bolts, and is locked and fixed by nuts.

[0030] One end of the stop block 44 is fitted with an adjusting plate 442, which has a slotted hole 443. The mounting positioning block 43 is connected to the adjusting plate by bolts passing through the slotted hole 443. After loosening the nut, the adjusting plate 442 can slide along the slotted hole 443 (to achieve fine adjustment of the position of the stop block 44 in the front-back / left-right direction). After adjustment, the nut is tightened to fix the position by the friction between the bolt and the slotted hole. No need to replace the stop block; it can be adapted to different shoe sizes (e.g., 35-44) and styles (sports shoes / leather shoes) by simply sliding and adjusting (different shoe upper curvatures and widths require different stop block positions), reducing the adaptation cost of "one shoe, one mechanism"; the strip hole 443 provides sufficient adjustment stroke, and after the nut is tightened, it can prevent the stop block 44 from shifting due to vibration during the glue application process, avoiding the defects of existing fixed stop blocks that are "unadjustable and easy to loosen"; the adjustment process does not require disassembling the components, and can be completed by simply tightening and loosening the nut, which can be operated by a single person, shortening the changeover adjustment time.

[0031] Furthermore, the flexible material is an elastic plastic or nitrile rubber.

[0032] Choose elastic plastic or nitrile rubber – elastic plastic has good deformation recovery (it does not permanently deform after repeated self-adaptation), while nitrile rubber combines elasticity and resistance to adhesive corrosion (it can withstand polyurethane and neoprene commonly used in shoemaking); both materials are suitable for the normal temperature and humidity environment of shoemaking workshops, are odorless, not easy to age, and can maintain flexibility for a long time. The corrosion resistance and aging resistance of elastic plastic / nitrile rubber are more than 3 times that of ordinary flexible materials (such as soft rubber), reducing the frequency of block replacement; the deformation recovery ensures that the block can return to its initial position after more than 44 adaptations to the shoe upper, avoiding the decline in self-adaptation ability caused by material fatigue; the odorless material will not pollute the shoe upper or affect the workshop environment, avoiding the environmental hazards of existing inferior flexible materials.

[0033] Furthermore, such as Figure 1 , Figure 2 As shown, side baffles 441 for external protection of the brush side are installed on both sides of the block 44.

[0034] Side baffles 441 are installed on both sides of the block 44, extending to the outside of the side of the brush (without contacting the brush bristles); their core function is to block the glue splashing from the side when the brush rotates at high speed; the side baffles 441 move synchronously with the block 44 (including front and rear adjustment and angle self-adaptation), always covering the side of the brush, forming an all-round system of "front glue blocking + side protection". This design addresses the issue of existing systems only providing frontal glue protection, resulting in glue splattering and contaminating the shoe upper edges / upper. This further reduces the defect rate. The side panels do not contact the brush, avoiding interference with brush rotation and glue application. The design adaptively adjusts with the block, ensuring effective protection at any angle with no blind spots. The side panels are directly integrated into the block, eliminating the need for additional independent side panels, reducing the number of components and the size of the equipment.

[0035] The adjustable floating mechanism for glue application equipment of this utility model is used in the following steps: 1. Preparation stage before the operation (refer to Figure 1-3) Equipment inspection and adjustment: Remove the protective parts (if any) from the stop block 44, and check if the side baffle 441 is intact (as shown in Figures 1 and 2); loosen the bolts and nuts through the slot 443 of the adjusting plate 442 (as shown in Figures 1-3), and slide to adjust the front-back / left-right position of the stop block 44 to match the size (e.g., size 35-44) and style (sports shoes / leather shoes) of the shoes to be brushed, and tighten the nuts to fix it after adjustment; check if the bearing cover 41 (as shown in Figures 1-3) covers the bearing of the brush spindle 6, and ensure that there is no glue residue clogging it; adjust the initial stroke of the cylinder 42 to keep the stop block 44 at a safe initial distance from the shoe surface (to avoid collision); Robot and glue preparation: The data of the shoe upper contour points scanned by the 3D camera is transmitted to the robot, and the robot positions the mechanism (aligning the brush with the initial glue application point); the glue level in the glue tank 8 is checked, and the on / off sensitivity of the glue dispensing valve 1 is adjusted to ensure that the glue delivery path (glue tank 8 - glue dispensing valve 1 - rotary joint 5 - brush spindle 6) is unobstructed. 2. Power start-up and brush rotation stage (refer to Figure 3) Start motor 2 (installed on the upper part of main body plate 7), the motor output shaft drives transmission wheel 3 to rotate; transmission wheel 3 drives brush main shaft 6 to rotate through meshing / friction transmission (such as synchronous belt pulley transmission), and the brush at the end of the main shaft rotates synchronously with the main shaft - because motor 2 and bottom floating component 4 are spatially separated, the transmission process will not interfere with cylinder 42 and stop block 44, and the brush speed is stable (avoiding local glue overflow caused by fluctuation). 3. Adaptive adjustment stage of glue delivery and floating mechanism (refer to Figure 1-3) Adhesive delivery started: Turn on the glue supply switch of glue tank 8, and the glue flows to the glue dispensing valve 1 under pressure; the robot issues a glue brushing command, the glue dispensing valve 1 opens, and the glue flows into the brush spindle 6 through the glue tube and rotary joint 5 (as shown in Figure 3), and finally flows from the outlet of the spindle near the brush to the brush bristles. The brush applies the glue to the shoe surface while rotating. Adaptive motion of floating mechanism: The robot-driven mechanism moves along points on the shoe upper (such as the arch and toe corner areas). When the stop block 44 contacts the shoe upper, the flexible material (elastic plastic / nitrile rubber) deforms with the arc of the shoe upper, adaptively adjusting the angle (as shown in Figures 1 and 2) to reduce contact resistance and prevent the robot from triggering an emergency stop. If the change in the curvature of the shoe upper causes the distance between the stop block 44 and the shoe upper to shift, the cylinder 42 drives the stop block 44 to move back and forth in real time, dynamically adjusting the distance—preventing glue overflow due to excessive distance (the side baffle 441 simultaneously blocks glue splashes from the side) and preventing collisions from aggravating due to excessive distance. During this process, the bearing cover 41 continuously protects the bearing of the brush spindle 6, preventing dripping glue and dust from entering, ensuring smooth rotation of the spindle, and indirectly maintaining the stable speed of the brush. 4. Work completion and reset phase (refer to Figure 1-3) Stop power and glue delivery: After the robot completes the last glue application point, the glue dispensing valve 1 closes to stop glue delivery, the motor 2 stops running, and the brush spindle 6 and the brush stop rotating; Floating mechanism reset: Cylinder 42 drives stop 44 back to its initial position, disengaging from the shoe upper; if the shoe style is changed later, the position of the stop can be finely adjusted again through the strip hole 443 of the adjustment plate 442; Equipment maintenance: The robot drives the mechanism back to the initial work position. The operator cleans the residual glue on the stop 44 and side baffle 441, checks whether the bearing cover 41 is intact, and replenishes the glue bucket 8 to prepare for the next batch of glue application.
