Description

Technical Field

[0002] In the current footwear industry, shoe uppers typically have multi-angle curves and textured surfaces (such as logos and stitching). Traditional spray nozzles struggle to achieve uniform spraying, often resulting in missed areas or uneven coating thickness (industry standard ±0.25mm, actual error greater than ±0.5mm). Details such as the seam between the sole and upper, and the tongue may be obstructed, leading to incomplete spraying and requiring manual touch-ups.

[0084] The positioning and clamping fixture 20, coating fixture assembly 30, glue bucket assembly 40, and three-axis linkage assembly 50 are all mounted on the machine body 10.

[0085] Preferably, the first cylinder 201 is a pen-shaped cylinder.

[0086] To better illustrate the technical effects of this utility model, the present utility model provides the following specific embodiments to explain the above technical process:

[0087] Example 1: An adaptive coating device for irregular shoe uppers includes a machine body 10, a positioning and clamping fixture 20, a coating fixture assembly 30, a glue bucket assembly 40, and a three-axis linkage assembly 50. The positioning and clamping fixture 20 is connected to the machine body 10 via a mounting plate, the three-axis linkage assembly 50 is connected to the machine body 10 via a mounting plate, the glue bucket assembly 40 is placed on the machine body 10, and the coating fixture assembly 30 is mounted on the three-axis linkage assembly 50 with screws.

[0088] The positioning and clamping fixture 20 is pushed by the first cylinder 201, and the linear guide rail 205 is extended and retracted as a whole to complete the translation of the clamping component. The jaws 203 are clamped in parallel through the cam groove mechanism. The cam groove is a 45-degree inclined groove distributed on both sides of the guide rail. The jaws 203 on both sides are accurately inserted into the positioning holes of the shoe last through the positioning pins 2032 to ensure that the shoe last is clamped in the center and improve the reference of the carrier during the glue application process.

[0089] The glue tank assembly 40 for footwear coating agent equipment is a closed-loop control system. The flow rate data is given by the host computer, and a flow sensor is installed at the end of the glue hose. During operation, the flow rate is monitored in real time through the flow sensor data. The controller drives the electric proportional valve and adjusts it in real time to achieve flow stability.

[0090] like Figure 1 As shown, this utility model is an adaptive coating device for treating irregular shoe uppers, comprising a machine body 10, a positioning and clamping fixture 20, a coating fixture assembly 30, a glue bucket assembly 40, and a three-axis linkage assembly 50.

[0091] like Figure 2As shown, this utility model relates to a positioning and clamping fixture 20 for an adaptive coating device for irregular shoe uppers. A photoelectric sensor 202 senses the shoe and receives a signal. A first cylinder 201 extends and moves forward via a linkage mechanism and linear guide 205, reaching a hydraulic buffer 204. The grippers 203 then move laterally to clamp the shoe last. The grippers 203 are Z-shaped and include a gripper base plate 601, a gripper inclined plate 602, and a gripper top plate 603 connected in sequence. Under the action of the cylinder, the grippers 203 on both sides retract simultaneously. Positioning pins 2032 are inserted into the positioning holes of the shoe last, and the abutment plates 605 of the gripper top plates 603 abut against the pins. The gripper inclined plates 602 and the slots 604 hold the shoe last positioning components, resulting in a centered and precisely positioned shoe last.

[0092] like Figure 3 , Figure 6 , Figure 7 As shown, this utility model relates to a coating fixture assembly 30 for an adaptive coating device for irregular shoe uppers. A dispensing nozzle 304 is mounted on a dispensing valve 302. A sliding cylinder 303 enables the nozzle to float, addressing the unevenness of the shoe upper. An air nozzle 301 diffuses the adhesive, moving it below the adhesive trajectory and facing the front of the dispensing nozzle 304. A precision proportional valve controls the pressure, ensuring a suitable airflow range for greater adhesive coverage and stronger adhesion. A calibration tip 305 is used for calibration with offline programming, enabling faster trajectory generation and shorter debugging time.

[0093] like Figure 4 As shown, the glue tank assembly 40 of this utility model is used in an adaptive coating device for irregular shoe uppers. The air pressure is precisely regulated by an electro-proportional valve 401, ensuring a relatively stable output state for the glue tank 403, resulting in consistent, uninterrupted, and non-overflowing glue dispensing. A manual valve 402 allows for easy switching of the air path, facilitating replacement and maintenance. The glue dispensing volume can be controlled by an existing high-precision intelligent microfluidic control valve (error ±0.5%), reducing glue waste by 30%–50% compared to traditional manual glue application.

[0094] like Figure 5The invention relates to a three-axis linkage component 50 for an adaptive coating device for irregular shoe uppers. This component, through an embedded lead screw module assembly (X-axis movement component 501, Y-axis movement component 502, and Z-axis movement component 503), forms a mobile device in the X, Y, and Z directions. A servo motor 504 is installed, and through electrical program algorithms, the dispensing trajectory is made more precise, efficient, and stable. A distance sensor 505 mounted on the coating fixture assembly 30 detects the distance between the shoe last and the device. An external control device controls the X-axis movement component 501, Y-axis movement component 502, and Z-axis movement component 503 based on this distance, ensuring that the dispensing nozzle 304 maintains a fixed distance from the shoe upper in real time. This improves the positional accuracy of the coating agent and reliably guarantees the quality of the shoe upper treatment.

[0095] This embodiment has the following advantages:

[0096] (1) This utility model uses a high-precision multi-axis positioning module and an intelligent glue applicator to coordinate control, and combines a real-time feedback distance sensor 505 to detect the distance between the shoe last and the device, thereby calculating the real-time deviation. This enables precise adaptive coating of irregular shoe surface, effectively solving the technical problems of uneven coating, unclear edge lines, and scattered spots in traditional equipment. It significantly improves the positional accuracy of the coating agent and ensures the reliable quality of shoe surface treatment.

[0097] (2) This utility model adopts the combination of intelligent replaceable nozzle system and precision fluid control unit, and realizes dynamic adjustment of the trajectory posture and glue output of coating mode through laser ranging compensation algorithm, which significantly improves the adaptability of the treatment agent to shoe uppers of different materials and makes the coating boundary clearer.

[0098] (3) This utility model adopts contactless production, eliminating the risk of direct skin contact from manual glue application.

[0099] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
