Description

Technical Field

[0001] This invention relates to the technical field of vacuum adsorption, specifically to an in-mold high-efficiency vacuum adsorption positioning device for IMD. Background Technology

[0002] In industrial production, vacuum adsorption positioning devices are widely used for gripping, handling, and positioning various workpieces, playing a particularly important role in IMD (In-Mold Decoration), thin film processing, and electronic product assembly. Their working principle primarily involves generating negative pressure through a vacuum generator, which then adsorbs the workpiece at a preset adsorption point, thus achieving stable fixation and ensuring the precision of subsequent processing or assembly procedures.

[0003] In existing vacuum adsorption positioning devices, the adsorption points are usually designed as an integral part of the device body or fixedly installed. Specifically, the position of the adsorption point is predetermined during the device manufacturing process, for example, by directly machining suction holes on the mold template or mounting plate, or by fixing suction inserts. The number and distribution of the adsorption points are fixed structures.

[0004] However, this fixed adsorption point design has obvious limitations. When it is necessary to adsorb and position workpieces of different sizes, shapes or materials, the fixed adsorption points often cannot match the optimal adsorption position of the new workpiece. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an IMD in-mold high-efficiency vacuum adsorption positioning device, which has the advantages of allowing users to easily adjust the position of the adsorption point according to the shape of the object, and solves the problem that fixed adsorption points often cannot match the optimal adsorption position of new workpieces.

[0006] To achieve the aforementioned goal of allowing users to easily adjust the position of the adsorption point according to the shape of the item, this invention provides the following technical solution: an IMD in-mold high-efficiency vacuum adsorption positioning device, comprising a square frame, with sliding grooves on both the front and rear walls of the square frame, two movable frames arranged inside the square frame, sliders fixedly installed on the front and rear sides of the two movable frames, four sliders being movably connected to the two sliding grooves respectively, two connecting boxes being movably connected inside the two movable frames, an adsorption head being fixedly connected to the lower wall of each connecting box, a circular plate being fixedly sleeved on each connecting box, the lower side of each circular plate being respectively attached to the upper side of the two movable frames, and a short tube being fixedly connected to each connecting box.

[0007] Preferably, both of the two movable frames have horizontal grooves on their left and right sides, and extrusion strips are movably connected in both horizontal grooves. A flexible plate is fixedly installed on each extrusion strip, and a vertical block is fixedly installed on each slider. Grooves are opened on the left and right sides of each vertical block and the left and right sides of each slider, and each extrusion strip is movably connected to each groove.

[0008] Preferably, each vertical block has vertical grooves on both the left and right sides, each vertical groove is movably connected to a vertical strip, each vertical strip is fixedly installed with a square strip, each square strip is fixedly installed with a triangular strip on its lower side, and each vertical block has a connecting groove on its upper side.

[0009] Preferably, each of the connecting slots is connected to each vertical slot, and each connecting slot is provided with a top bar, and each top bar is fixedly connected to each vertical bar.

[0010] Preferably, each of the connecting grooves has a circular groove on its lower inner wall, and a pressure spring is provided in each circular groove. Each pressure spring is fixedly connected to each top bar.

[0011] Preferably, four support rods are fixedly installed on the upper side of the frame, and brackets are fixedly installed on each of the four support rods. Four cylinders are fixedly installed on the brackets, and two lifting bars are provided on the four cylinders. The lower ends of the output shafts of the four cylinders are fixedly connected to the two lifting bars respectively.

[0012] Compared with the prior art, this invention provides a high-efficiency vacuum adsorption positioning device for IMD (In-Mold Design), which has the following advantages:

[0013] 1. This IMD in-mold high-efficiency vacuum adsorption positioning device can move back and forth within the moving frame via a connecting box to adjust its position. This allows the adsorption head to move back and forth. By using a slider in conjunction with a sliding groove, the moving frame can move left and right, allowing the adsorption head to move left and right back and forth. This allows the adsorption head to be moved back and forth to adjust its position, making it convenient for users to adjust according to the shape of the item.

[0014] 2. This IMD in-mold high-efficiency vacuum adsorption positioning device, after adjusting the position by moving the adsorption head back and forth, can activate the cylinder to drive the two lifting bars to move downwards, thus squeezing each top bar downwards, which in turn drives each square bar and three-strip bar downwards, thereby squeezing the extrusion bar in the groove. This extrusion bar can then use the soft plate to squeeze the connecting box and fix it. At the same time, the downward-pressing lifting bar drives the top bar into the connecting groove, and the continued pressure will fix the vertical block, thus quickly fixing the adsorption head that has been adjusted to a certain position.

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

[0021] Please see Figures 1-3 This invention provides a technical solution: an IMD (In-Mold Deposition) high-efficiency vacuum adsorption and positioning device, comprising a square frame 1, with sliding grooves 25 abutting the front and rear walls of the square frame 1. Two movable frames 7 are disposed within the square frame 1, with sliders 22 fixedly installed on the front and rear sides of each movable frame 7. The four sliders 22 are movably connected to the two sliding grooves 25 respectively. Two connecting boxes 10 are movably connected within each movable frame 7. An adsorption head 9 is fixedly connected to the lower wall of each connecting box 10. A circular plate 12 is fixedly fitted onto each connecting box 10, with the lower side of each circular plate 12 abutting the upper side of each of the two movable frames 7 respectively. A short tube 13 is fixedly connected to each connecting box 10. The position of the adsorption head 9 can be adjusted by moving the connecting box 10 back and forth within the movable frame 7. The sliders 22, in conjunction with the sliding grooves 25, allow the movable frame 7 to move left and right back and forth, thus allowing the adsorption head 9 to move left and right back and forth, adjusting its position. This allows users to easily adjust the position according to the shape of the object.

[0022] Both sides of the two movable frames 7 are provided with horizontal grooves 11. Each horizontal groove 11 is movably connected with an extrusion strip 23. Each extrusion strip 23 is fixedly installed with a flexible plate 24. Each slider 22 is fixedly installed with a vertical block 6. Each vertical block 6 and each slider 22 are provided with grooves 8 on their left and right sides. Each extrusion strip 23 is movably connected to each groove 8.

[0023] Each vertical block 6 has vertical grooves 21 on both the left and right sides, and vertical strips 14 are movably connected to each vertical groove 21. A square strip 17 is fixedly installed on each vertical strip 14, and a triangular strip 18 is fixedly installed on the lower side of each square strip 17. A connecting groove 20 is opened on the upper side of each vertical block 6.

[0024] Each connecting groove 20 is connected to each vertical groove 21, and a top bar 16 is provided in each connecting groove 20. Each top bar 16 is fixedly connected to each vertical bar 14.

[0025] Each connecting groove 20 has a circular groove 19 on its inner wall, and a pressure spring 15 is installed in each circular groove 19. Each pressure spring 15 is fixedly connected to each top bar 16.

[0026] Four support rods 2 are fixedly installed on the upper side of the frame 1. Each of the four support rods 2 is fixedly installed with a bracket 5. Four cylinders 4 are fixedly installed on the brackets 5. Two lifting bars 3 are set on the four cylinders 4. The lower ends of the output shafts of the four cylinders 4 are fixedly connected to the two lifting bars 3 respectively. After adjusting the position by moving the adsorption head 9 back and forth, the cylinders 4 can be activated to drive the two lifting bars 3 to move downward. This will squeeze each top bar 16 downward, which will drive each square bar 17 and the three-strip bar 18 to move downward, thereby squeezing the extrusion bar 23 in the groove 8. The extrusion bar 23 can then drive the soft plate 24 to squeeze the connecting box 10 and fix it. At the same time, the downward-pressing lifting bars 3 drive the top bars 16 into the connecting groove 20 and continue to apply pressure to fix the vertical block 6, thereby quickly fixing the adsorption head 9 that has been adjusted in position.
