Description

Technical Field

[0001] This utility model relates to the field of foam bonding technology, specifically to a foam bonding fixture. Background Technology

[0002] In fields such as electronics manufacturing, automotive interiors, and home appliance assembly, foam is widely used for filling gaps between components, surface protection, and sound insulation and noise reduction due to its properties such as cushioning, sealing, and shock absorption.

[0003] The fixture consists of a precision positioning platform, a foam fixing mechanism, an automatic pressing component, a release paper peeling unit, and a control module. After the workpiece to be pasted is fixed on the positioning platform, the foam is placed into the fixing mechanism and the release paper is removed by the release paper peeling unit. The positioning platform moves the workpiece to directly below the foam, and the automatic pressing component moves down to complete the precise pressing and pasting. Finally, the platform resets and the finished product is taken out.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional tooling mostly uses mechanical grippers to grasp foam. The foam is soft and easily deformed, which leads to the deviation of the gripping position. Positioning depends on manual visual inspection. The foam and the workpiece are not aligned accurately, resulting in misalignment or wrinkles after pasting. In view of this, we propose a foam pasting tooling. Utility Model Content

A collecting frame is snapped onto the output end of the collecting motor. A conveying frame is rotatably installed on the high bracket. A support block is fixedly installed on the base plate. A tension roller is provided on the support block, a cylinder is fixedly installed on the base plate, a limit ring is fixedly installed on the support block, one end of a tension spring is fixedly installed inside the cylinder, one end of a vertical rod is fixedly installed on the other end of the tension spring, and an electrostatic roller is rotatably installed on the other end of the vertical rod.

[0007] In a further embodiment, multiple sets of the spring rod, tension roller, cylinder, limiting ring, tension spring, and vertical rod are provided.

[0008] In a further embodiment, the vertical rod slides inside the limiting ring and the cylinder, one end of the foam workpiece is placed on the conveying frame, the other end of the foam waste is placed on the collecting frame, and the foam workpiece passes through multiple sets of tension rollers.

[0009] In a further embodiment, the foam workpiece is positioned above the support block, the support block and the foam workpiece are positioned below the suction head, and the horizontal electric slide rail, the vertical electric slide rail, the pressing frame, the spring rod and the suction head are positioned above the conveying device.

[0010] In a further embodiment, the base plate is provided with an auxiliary component, which includes a right-angle frame. The right-angle frame is fixedly installed at the bottom of the base plate, and an mounting plate is fixedly installed on the right-angle frame. A limit plate is fixedly installed on the mounting plate, and a hydraulic device is fixedly installed on the mounting plate. A support plate is fixedly installed at the piston end of the hydraulic device, and an arc-shaped plate is fixedly installed above the support plate.

[0011] In a further embodiment, multiple sets of the right-angle frame, limiting plate, arc plate, and limiting rod are provided, with the multiple sets of limiting rods penetrating through the limiting plate.

[0012] In a further embodiment, the pallet is positioned directly below the empty trough, and both the pallet and the empty trough are positioned below the conveying device.

[0013] Compared with the prior art, this utility model provides a foam bonding fixture, which has the following beneficial effects: 1. This foam pasting fixture, in order to meet the needs of mass production, is equipped with a pasting component. This component, together with the horizontal and vertical electric slide rails, drives the pressing frame to move, causing the suction head to accurately align with the foam workpiece. The suction head uses negative pressure to adsorb the foam, preventing deformation of the foam during gripping. The spring rod provides buffer pressure during pasting, ensuring that the foam adheres tightly to the workpiece on the conveying device. At the same time, the tension roller on the support block, together with the tension spring-pulled vertical rod and the electrostatic roller, levels and removes static electricity from the foam workpiece, preventing the foam from attracting impurities due to static electricity. The collection motor drives the collection frame to collect foam waste, reducing waste accumulation.

[0014] 2. To meet the requirements of high-precision foam bonding processes, this foam bonding fixture is equipped with an auxiliary component. When the conveying device transports the workpiece to be bonded to below the adsorption head, this component, in conjunction with the hydraulic device, pushes the support plate upward along the guide rod. The arc-shaped plate closely fits the front and rear ends of the workpiece, providing stable support for the workpiece and preventing foam displacement caused by the workpiece sinking during bonding. The limit plate restricts the maximum rising height of the support plate, ensuring a constant distance between the workpiece and the adsorption head and guaranteeing uniform bonding pressure.

[0020] In one embodiment of this utility model, an adhesive assembly 4 is provided on the base plate 1.

A vertical electric slide rail 43 is fixedly mounted on the sliding part of the horizontal electric slide rail 42. A pressing frame 44 is fixedly mounted on the sliding part of the vertical electric slide rail 43. One end of a spring rod 45 is fixedly mounted on the pressing frame 44, and an adsorption head 46 is fixedly mounted on the other end of the spring rod 45. A high bracket 47 and a low bracket 48 are fixedly mounted on the base plate 1. A collecting motor 49 is fixedly mounted on the low bracket 48, and a collecting frame 410 is snapped onto the output end of the collecting motor 49. A conveying frame 411 is rotatably mounted on the high bracket 47. A support block 412 is fixedly mounted on the base plate 1, and a tension roller 413 is provided on the support block 412. A cylinder 414 is fixedly mounted on the base plate 1. A limiting ring 415 is fixedly installed on the upper part of the cylinder 414.

An electrostatic roller 418 is rotatably installed on the other end of the vertical rod 417. Multiple sets of spring rod 45, tension roller 413, cylinder 414, limiting ring 415, tension spring 416 and vertical rod 417 are arranged. The vertical rod 417 slides inside the limiting ring 415 and cylinder 414. One end of a foam workpiece 6 is placed on the conveyor frame 411. One end of a foam waste is placed on the collection frame 410. The foam workpiece 6 passes through multiple sets of tension rollers 413. The foam workpiece 6 is set above the support block 412.

A horizontal electric slide rail 42, a vertical electric slide rail 43, a pressing frame 44, a spring rod 45 and a suction head 46 are set above the conveyor device 2.

[0021] In this embodiment, firstly, one end of the foam workpiece 6 is placed on the conveyor frame 411 of the high support 47, and the other end passes through multiple sets of tension rollers 413 of the support block 412. The waste foam end is fixed on the collection frame 410 of the low support 48. The collection motor 49 is started, driving the collection frame 410 to rotate slowly, cooperating with the conveyor frame 411 to convey the foam workpiece 6. At the same time, the tension spring 416 inside the cylinder 414 pulls the vertical rod 417 to slide along the limiting ring 415, so that the electrostatic roller 418 is tightly attached to the surface of the foam workpiece 6. During the foam conveying process, the tension roller 413 flattens the foam, and the electrostatic roller 418 eliminates static electricity on the foam surface to prevent the adsorption of impurities from affecting the bonding effect. When the conveying device... 2. When the workpiece to be pasted is conveyed to the area below the suction head 46, the horizontal electric slide rail 42 on the mounting frame 41 drives the vertical electric slide rail 43 to move horizontally. The vertical electric slide rail 43 drives the pressing frame 44 and the suction head 46 to move vertically, so that the suction head 46 is precisely aligned with the foam workpiece 6. The suction head 46 uses negative pressure to adsorb the foam, avoiding deformation of the foam during gripping. Subsequently, the horizontal electric slide rail 42 and the vertical electric slide rail 43 work together to convey the foam above the workpiece to be pasted. The suction head 46 descends, and the spring rod 45 provides buffer pressure at the moment of pasting, ensuring that the foam adheres tightly to the surface of the workpiece and completing the pasting. The foam waste generated during pasting is continuously recycled by the collection frame 410 to reduce waste accumulation.

[0022] In one embodiment of this utility model, an auxiliary component 5 is provided on the base plate 1. The auxiliary component 5 includes a right-angle frame 51. The right-angle frame 51 is fixedly installed at the bottom of the base plate 1. An mounting plate 52 is fixedly installed on the right-angle frame 51.

[0023] In this embodiment, when the conveying device 2 transports the workpiece to be pasted to directly below the adsorption head 46, the hydraulic device 54 of the mounting plate 52 on the right-angle frame 51 is activated. Its piston end pushes the support plate 55 upward along the guide rod 57. The support plate 55 passes through the slot 58 of the base plate 1, and the arc plate 56 at the top fits tightly against the front and rear ends of the workpiece, providing stable support for the workpiece and preventing the foam from shifting due to the workpiece sinking under pressure during pasting. When the support plate 55 rises to the set height, the limit plate 53 restricts the support plate 55 from continuing to rise, ensuring that the distance between the workpiece and the adsorption head 46 is constant, so that the pressure during pasting is uniform and consistent, ensuring that the foam pasting effect of each workpiece is the same. After pasting is completed, the hydraulic device 54 drives the support plate 55 to reset.
