Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for applying adhesive to vehicle window glass. Background Technology

[0002] In the production of laminated glass for automotive windows, the adhesive application process is crucial for ensuring the glass's seal, sound insulation, and waterproofing against the vehicle body. Traditional adhesive application relies primarily on manual operation, where the window glass is placed on the application equipment and its position is manually adjusted to ensure accurate and even application. However, this manual method has the following significant drawbacks:

[0003] Low positioning accuracy: Manual adjustment makes it difficult to ensure the accuracy of glass position, which can easily lead to deviation of the glue application path, uneven glue layer thickness, or glue overflow, affecting product quality; Low efficiency: Manual operation is time-consuming, which is difficult to meet the needs of high-speed production lines, and requires high skill from operators, increasing training and time costs; Insufficient stability: Traditional glue application equipment lacks an effective positioning device, and the glass is prone to displacement due to vibration or external force during the glue application process, further reducing the glue application effect.

[0004] To overcome the aforementioned problems, some highly automated adhesive coating equipment has emerged in the prior art. These devices are typically equipped with positioning devices to improve the stability of the glass during the adhesive coating process. However, these positioning devices still have the following shortcomings:

[0005] Surface damage risk: Existing positioning devices mostly use rigid mechanical clamping, which can easily scratch the surface of the car window glass (especially coated or curved glass), affecting the product's appearance quality.

[0006] Complex structure and poor adaptability: Some positioning devices have complex structures, are cumbersome to operate, and have high maintenance costs.

[0007] Limited functionality: Existing devices mostly only achieve bottom fixation or lateral clamping, lacking a collaborative positioning mechanism, making it difficult to simultaneously meet the positioning requirements of high precision and non-destructive operation.

[0008] To address the aforementioned technical deficiencies, this invention proposes a positioning device for applying adhesive to vehicle window glass. Through a collaborative design of bottom vacuum adsorption and side pneumatic clamping, it achieves high-precision, damage-free glass positioning, significantly improving adhesive application quality and efficiency. This device not only solves the problems of low efficiency and poor precision in traditional manual operation but also overcomes the shortcomings of existing automated equipment, such as easy damage to glass and complex structure, thus possessing significant industrial application value.

[0033] Reference Figures 1-4 This invention provides a positioning device for applying adhesive to vehicle window glass, comprising a bottom positioning mechanism 100 and a side positioning mechanism 200. The bottom positioning mechanism 100 includes a vacuum suction cup 101 and a vacuum generating unit 102. The vacuum suction cup 101 is arranged on the vacuum generating unit 102 to adsorb the vehicle window glass to be coated, achieving stable bottom support and facilitating the coating process on the vehicle window glass. The vacuum generating unit 102 is connected to an exhaust pipe 103, which is connected to a vacuum pump 104. The vacuum pump 104 generates negative pressure, causing the vacuum suction cup 101 to tightly adsorb the lower surface of the vehicle window glass.

[0034] The side positioning mechanism 200 includes a side positioning clamp 201. Two sets of side positioning clamps 201 are arranged on the left and right sides of the vacuum generating unit 102, respectively, for lateral clamping of the window glass. A flexible pad 2011 is arranged on the side of the side positioning clamp 201 closest to the window glass to be coated with adhesive, which avoids scratching the surface of the window glass by the side positioning clamp 201 and protects the surface quality of the window glass. Furthermore, the flexible pad 2011 of the side positioning clamp 201 can be made of high elastic silicone material, combined with the negative pressure adsorption buffer mechanism of the passive suction cup 205, to avoid scratches on the glass surface caused by hard contact, which is especially suitable for precision processing of coated glass. A control box 202 is connected to the bottom of the vacuum generating unit 102. Pull rod slide rails 203 are opened on both the left and right sides of the control box 202. A control pull rod 204 is horizontally slidably connected in the pull rod slide rail 203, and the control pull rod 204 is connected to the bottom of the side positioning clamp 201.

[0035] Each set of side positioning clamps 201 has a set of control rods 204 arranged on both the left and right sides. The cross-section of the control rods 204 is L-shaped. The L-shaped cross-section design of the control rods 204 optimizes the force transmission path and ensures the synchronization and stability of the clamping action. The two sets of control rods 204 on both sides of the vacuum generator 102 are arranged symmetrically. The top of the control rods 204 is fixedly connected to the side positioning clamps 201, and the bottom of the control rods 204 is slidably connected to the rod slide rail 203. The rod slide rail 203 has a rod groove 2031 adapted to the structure of the control rods 204. The rod slide rail 203 inside the rod groove 2031 has a suction cup groove 2032 adapted to the structure of the passive suction cup 205. The air extraction channel 206 is arranged between the two sets of suction cup grooves 2032, and the two ends of the air extraction channel 206 are respectively connected to the two sets of suction cup grooves 2032.

[0036] Each set of control levers 204 has a set of passive suction cups 205 fixedly connected to one end. An air extraction channel 206 is provided in the lever slide rail 203 between the two sets of passive suction cups 205. A spring 207 is arranged in the air extraction channel 206. The two sets of passive suction cups 205 are connected by the spring 207. The top end of the air extraction channel 206 is connected to a connecting branch pipe 208. The other end of the connecting branch pipe 208 is connected to the exhaust pipe 103.

[0037] With the cooperation of vacuum pump 104, exhaust pipe 103, and connecting branch pipe 208, the air between the two sets of passive suction cups 205 is discharged through the air extraction channel 206, causing the two sets of passive suction cups 205 to move closer to each other. Then, the suction force drives the control lever 204 to slide, thereby adjusting the position of the side positioning clamp 201 to achieve the purpose of lateral clamping of the car window glass. When vacuum pump 104 stops working, passive suction cup 205 slides outward under the action of spring 207, and the side positioning clamp 201 releases the clamping force on the car window glass.

[0038] The specific implementation steps of this positioning device are as follows:

[0039] Glass placement and initial positioning:

[0040] Place the car window glass to be coated with adhesive on the vacuum suction cup 101, start the vacuum pump 104, and create a negative pressure in the vacuum generating part 102 through the exhaust pipe 103, so that the vacuum suction cup 101 can adsorb and fix the lower surface of the glass.

[0041] Lateral clamping adjustment:

[0042] When the vacuum pump 104 is running, the negative pressure is transmitted to the air extraction channel 206 through the connecting branch pipe 208, which extracts the air between the two sets of passive suction cups 205, causing the passive suction cups 205 to slide towards the center under the action of pressure difference, compressing the spring 207.

[0043] The sliding motion of the passive suction cup 205 drives the control rod 204 to move horizontally along the rod groove 2031, driving the side positioning clamp 201 to move closer to the glass side, and the flexible pad 2011 contacts the glass and applies a uniform clamping force.

[0044] The adhesive application process remains stable.

[0045] The side positioning clamp 201 and the bottom vacuum suction cup 101 work together to ensure that the glass is constrained in multiple directions, which facilitates the subsequent coating equipment to apply adhesive to the surface of the glass.

[0046] Clamping, releasing, and removing parts:

[0047] After the adhesive is applied, the vacuum pump 104 is turned off, the negative pressure between the passive suction cups 205 disappears, the spring 207 pushes the passive suction cups 205 to reset, and drives the control lever 204 and the side positioning clamp 201 to exit the clamping state, so that the glass can be safely removed.

[0048] In this scheme, the vacuum pump 104 serves as the sole power source. Through the gas path topology design (exhaust pipe 103 → connecting branch pipe 208 → air extraction channel 206), it synchronously drives the adsorption and clamping actions, achieving a highly efficient and energy-saving effect of "one pump, two controls".

[0049] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
