[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A vacuum dispensing device for easy workpiece handling includes a housing 1, a vacuum dispensing chamber inside the housing 1, an inlet / outlet 2 at the front of the housing 1 corresponding to the vacuum dispensing chamber, a guide support platform 3 installed on the front of the housing 1, a movable support platform 4 inside the vacuum dispensing chamber, the guide support platform 3 and the movable support platform 4 are arranged along the same straight line and are spaced apart, a carrier plate 5 is provided on both the guide support platform 3 and the movable support platform 4, the carrier plate 5 can slide sequentially on the guide support platform 3 and the movable support platform 4 along the same straight line, and the width of the carrier plate 5 is greater than the distance between the guide support platform 3 and the movable support platform 4;

[0024] Both ends of the carrier plate 5 are provided with grooves 8, and a thin metal plate 9 is installed inside the grooves 8. A limit block 10 is fixedly connected to one end of the top of the movable support platform 4. An adsorption block 11 is fixedly connected to the side of the limit block 10 near the carrier plate 5. A magnetic column is provided on the side of the adsorption block 11 near the thin metal plate 9.

[0025] Using the above technical solutions, the vacuum dispensing chamber inside the box 1 provides a bubble-free environment for dispensing operations, ensuring dispensing quality; the inlet and outlet 2, together with the guide support platform 3 and the movable carrier platform 4 arranged in a straight line, realizes the smooth transition of the carrier plate 5, and the width of the carrier plate 5 is greater than the interval between the two carrier platforms to avoid suspension during sliding; the limiting block 10 on the movable carrier platform 4 restricts the sliding end point of the carrier plate 5, and the magnetic column of the adsorption block 11 is magnetically fixed to the metal plate 9 in the groove 8 of the carrier plate 5 to prevent the carrier plate 5 from shifting during dispensing, laying the foundation for accurate dispensing.

[0026] Both the top sides of the guide support platform 3 and the movable bearing platform 4 are equipped with arc-shaped guide rails 6, and both sides of the bottom of the carrier plate 5 are provided with matching guide grooves 7 corresponding to the positions of the arc-shaped guide rails 6. The cross-sections of the arc-shaped guide rails 6 and the matching guide grooves 7 are both arc-shaped.

[0027] By adopting the above technical solutions and optimizing the guide structure at the top of the guide support platform 3 and the movable carrier platform 4, the smoothness and stability of the carrier plate sliding are significantly improved. Among them, the arc-shaped guide rail 6 and the matching guide groove 7 at the bottom of the carrier plate 5 adopt an arc-shaped cross-section structure design. Compared with the traditional rectangular guide rail, the arc-shaped structure can reduce the contact area between the two, reduce the sliding friction resistance, and make it easier for the operator to push the carrier plate.

[0028] The top of the carrier plate 5 has multiple workpiece placement slots 12, and handles 13 are vertically installed at both ends of the top of the carrier plate 5.

[0029] Using the above technical solutions, the multiple workpiece placement slots 12 at the top of the carrier plate 5 can independently position one or more workpieces to be glued, avoiding collisions and displacement of workpieces during the sliding of the carrier plate or during glue filling. At the same time, it supports multiple workpieces to enter the vacuum glue filling chamber simultaneously for glue filling operations, effectively improving the single-processing efficiency of the equipment. The handles 13 vertically installed at both ends of the top of the carrier plate 5 provide convenient force points for operators, making it easy for operators to quickly push the carrier plate from the guide support platform 3 to the movable support platform 4, or pull the carrier plate out of the equipment after glue filling, reducing the difficulty of operation.

[0030] The front side of the housing 1 is provided with vertically extending guide rails on both sides of the entrance / exit 2. A sealing door 15 is slidably installed between the two guide rails. The size of the sealing door 15 is adapted to the entrance / exit 2. A drive cylinder 16 is vertically installed at the bottom front side of the housing 1. The extension end of the drive cylinder 16 is fixedly connected to the middle of the outer side of the sealing door 15.

[0031] Using the above technical solution, the vertical guide rails on both sides of the inlet / outlet 2 of the housing 1 provide stable lifting guidance for the sealing door 15. Because the sealing door 15 is adapted to the size of the inlet / outlet 2, it can completely cover the inlet / outlet to ensure the sealing of the vacuum dispensing chamber, maintain the vacuum environment, and prevent air from affecting the dispensing quality. At the same time, the drive cylinder 16 drives the sealing door 15 to automatically lift and lower, improving the automation level and sealing reliability of the equipment.

[0032] The vacuum potting cavity is equipped with a vacuum pump and corresponding connecting pipeline on its side to realize the vacuuming operation inside the cavity; since the vacuuming technology is a mature technology in the field, it will not be elaborated here for the sake of simplicity.

[0033] In addition, the gap between the guide support platform 3 and the movable carrier platform 4 provides sufficient space for the lifting and opening / closing of the sealing door 15 at the entrance / exit channel 2 of the main housing 1, avoiding structural interference between the sealing door 15 and the two carrier platforms when it moves. At the same time, the width of the carrier plate 5 is designed to be greater than the gap size, which ensures that the bottom of the carrier plate 5 is always supported when it slides from the guide support platform 3 to the movable carrier platform 4, without any suspension or jamming, and achieves a smooth transition between the two.

[0034] Both sides of the bottom of the guide support platform 3 are fixed with triangular fixing brackets 14, and the two triangular fixing brackets 14 are respectively fixed to the outer side of the two guide slide rails.

[0035] By adopting the above technical solution, the structural design of the triangular fixing frame 14 provides stable support for the guide support platform 3, ensuring the structural reliability of the carrier plate 5 during the transfer process.

[0036] An X-axis displacement drive module 17 is installed at the bottom of the inner side of the vacuum dispensing cavity, and a Y-axis displacement drive module 18 is installed on the top of the X-axis displacement drive module 17. The X-axis displacement drive module 17 can drive the Y-axis displacement drive module 18 to move along the X-axis direction. The top of the Y-axis displacement drive module 18 is connected to the movable support platform 4, and the Y-axis displacement drive module 18 can drive the movable support platform 4 to move along the Y-axis direction. A dispensing head 19 is provided at the top of the inner side of the vacuum dispensing cavity.

[0037] Using the above technical solutions, the X-axis displacement drive module 17 and the Y-axis displacement drive module 18 inside the vacuum dispensing cavity work together. Both are existing mature technologies, and they typically use a motor-driven ball screw transmission structure, including a drive motor, ball screw assembly, and guide and limit components. This structure can achieve precise linear displacement, and its specific structure will not be described in detail. It can drive the top-connected movable support platform 4 and carrier plate 5 to move precisely in both directions along the X and Y axes, delivering the workpieces to be dispensed on the carrier plate 5 one by one to the area directly below the dispensing head 19. This ensures that the dispensing head 19 can accurately and completely cover all workpieces with dispensing, avoiding dispensing omissions or positional deviations, and ensuring consistent dispensing quality.

[0038] Working principle:

[0039] The operator places the workpiece to be glued into the workpiece placement slot 12 of the carrier plate 5, and pushes the carrier plate 5 with the handle 13, so that it slides along the arc-shaped guide rail 6 on the top of the guide support platform 3 and the movable carrier platform 4. Since the width of the carrier plate 5 is greater than the distance between the two carrier platforms, it can smoothly transition from the guide support platform 3 to the movable carrier platform 4 until it is blocked by the limit block 10. At this time, the magnetic column of the adsorption block 11 and the metal plate 9 in the groove 8 of the carrier plate 5 magnetically attract and fix the carrier plate. Then, the drive cylinder 16 drives the sealing door 15 to rise along the guide slide rail, closing the inlet and outlet channel 2. The vacuum pump is used to evacuate the vacuum glue filling chamber to create a vacuum environment. Then, the X-axis displacement drive module 17 and the Y-axis displacement drive module 18 work together to drive the movable carrier platform 4 and the carrier plate 5 to move precisely along the X and Y axes, sending the workpieces one by one to the bottom of the glue filling head 19 for glue filling.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
