Description

Technical Field

[0001] This utility model relates to the technical field of product assembly, specifically a contour-following suction positioning fixture. Background Technology

[0002] In the manufacturing of electronic and electrical products, hot melt adhesive is used to assemble component products into a single unit, such as... Figure 1 The product shown has a central component 1 with two first steel plates 2 at its two ends along its length. Each first steel plate 2 needs to be connected to second steel plates 4 at both ends by hot melt adhesive 3. The inner ends of the second steel plates 4 are connected to the first steel plates 2 by hot melt adhesive 3. In the existing manufacturing process, the central component 1 needs to be manually pressed and positioned, and then hot melt adhesive 3 is applied to the first steel plates 2 at both ends. Then, the two sets of second steel plates 4 are successively hot melt adhered to the hot melt adhesive 3. The entire assembly process is inefficient, and because the central component 1 needs to be manually pressed and positioned, the positioning accuracy of the assembled product is relatively poor, which cannot meet the requirements of high-precision products. Therefore, there is an urgent need to develop a fixture that can improve the positioning accuracy of the product and has high assembly efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a contour-following suction positioning fixture, which reliably positions and adsorbs the central component, and ensures that the inner end of the second steel sheet is reliably aligned with the corresponding position of the first steel sheet of the central component, thereby improving positioning accuracy and assembly efficiency.

[0004] A contour-following suction positioning fixture, characterized in that it comprises:

[0005] The base plate is arranged along its length. The central area of ​​the base plate is recessed to form an inner groove that mimics the shape of the central component. Both ends of the base plate are recessed to form a lowered surface portion. Several air suction holes are arranged on the surface area of ​​the inner groove. An air suction chamber is provided inside the base plate. All the air suction holes are connected to the air suction chamber. The air suction chamber is connected to an external air suction notch. The air suction notch completes the reliable adsorption and positioning of the central component through an external air suction device. The lowered surface portion is provided with an upwardly convex positioning protrusion.

[0006] And a tray, which includes a central clearance notch, the central clearance notch being shaped to the surface area of ​​the base plate excluding the lowered portions at both ends, and the tray having positioning holes at both ends corresponding to the positioning protrusions in the length direction;

[0007] In the working state, the tray cover is mounted on the base plate and assembled by aligning with the positioning holes and positioning protrusions. The central component of the product is positioned in the inner groove and held in place. Two second steel plates are transferred to the inner end and aligned with the hot melt adhesive of the first steel plate. The outer end of the second steel plate in the length direction is pressed onto the upper surface of the corresponding end of the tray. Then, the hot melt adhesive is melted and fixed. After that, the tray is removed to take out the assembled product.

[0008] The presence of the tray allows for easy lifting with one hand, thus separating the product from the base plate, reducing the difficulty of picking up the product and improving assembly efficiency.

[0009] Its further features are:

[0010] The lowering height of the lowering section is equal to the thickness of the pallet. In the working state, the upper surface of the pallet is flush with the upper surface of the base plate.

[0011] The base plate is recessed on both sides of the middle part of the inner groove along its length to form a detection and adjustment notch. When the central component is observed to have a lateral bulge on one side, the alignment is adjusted through the detection and adjustment notch, making the alignment simple and convenient.

[0012] The base plate is made of aluminum alloy, which facilitates reliable heat transfer to the hot melt adhesive.

[0013] There are two positioning protrusions on the lowered surface portion at each end;

[0014] The two positioning protrusions are preferably conical structures that taper from bottom to top, which ensures that the tray is easily and quickly aligned.

[0015] Two second steel sheets are formed by punching the same steel sheet. The waste edges formed by punching are not excluded. The waste edges and the two second steel sheets are integrated onto a release film. The two ends of the release film protrude outward from the steel sheet, and alignment holes are punched out according to the positioning protrusions. Before punching, the position of the first steel sheet and the hot melt adhesive adhesion position are reliably measured in advance, so that the inner end of the second steel sheet is aligned with the hot melt adhesive position of the first steel sheet. When the second steel sheet is fed, the waste edges, the second steel sheet, and the release film are fed at the same time. The second steel sheet is arranged facing downwards, so that the two second steel sheets are fed at the same time and reliably aligned through the alignment holes, so that the inner end of the second steel sheet is precisely aligned with the hot melt adhesive position of the first steel sheet.

[0016] When the pallet pulls the product along with the waste edge corresponding to the second steel sheet and the release film off the bottom plate, the release film pulls the waste edge to discharge waste, thereby obtaining the product;

[0017] The tray is made of FR4 material to ensure stable and reliable shape when heated;

[0018] The inner groove is recessed by 0.2-0.25mm relative to the upper surface of the base plate. After the central component is embedded in the inner groove, the first steel sheet does not protrude from the upper surface of the base plate, and ensures that the hot melt adhesive has a accommodating space.

[0019] With the diameter of this utility model, in the working state, the tray cover is mounted on the base plate and assembled by aligning with the positioning holes and positioning protrusions. The central component of the product is positioned in the inner groove and held in place. Two second steel plates are transferred to the inner end and aligned with the hot melt adhesive of the first steel plate. The outer end of the second steel plate in the length direction is pressed onto the corresponding end of the upper surface of the tray. Then, the hot melt adhesive is melted and fixed. After that, the tray is removed to take out the assembled product. This reliably positions and adsorbs the central component, and makes the inner end of the second steel plate reliably aligned with the corresponding position of the first steel plate of the central component, thereby improving the positioning accuracy and assembly efficiency.

[0026] A contour-following suction positioning fixture, see 1- Figure 3 It includes a base plate 10 and a pallet 20;

[0027] The base plate 10 is arranged along the length direction. The central area of ​​the base plate 10 is recessed to form an inner groove 11 that imitates the central component 1. The two ends of the base plate 10 along the length direction are recessed to form a lowered surface portion 12. Several suction holes 13 are arranged on the surface area of ​​the inner groove 11. A suction cavity (not shown in the figure, which is a conventional technology) is provided inside the base plate 10. All the suction holes 13 are connected to the suction cavity. The suction cavity is connected to the external suction notch 16. The suction notch 16 completes the reliable adsorption and positioning of the central component 1 through the external suction equipment. The lowered surface portion 12 is provided with an upwardly convex positioning protrusion 14.

[0028] The pallet 20 includes a central clearance notch 21, which is shaped to the surface area of ​​the bottom plate 10 excluding the lowered surface portion 12 at both ends. The pallet 20 has positioning holes 22 at both ends of the length direction corresponding to the positioning protrusions 14.

[0029] Two second steel sheets 4 are punched and formed by the same steel sheet. The waste edge 5 formed by punching is not excluded. The waste edge 5 and the two second steel sheets 4 are integrated on a release film 6. The two ends of the release film 6 protrude outward from the steel sheet, and the alignment hole 61 is punched out according to the positioning protrusion 14. Before punching, the position of the first steel sheet 2 and the adhesion position of the hot melt adhesive 3 are reliably measured in advance, so that the inner end of the second steel sheet 4 is set to the position of the hot melt adhesive 3 located on the first steel sheet 2.

[0030] In the working state, the tray 20 is mounted on the base plate 10 and aligned with the positioning hole 22 and positioning protrusion 14 to form an assembly. The central component 1 of the product is positioned in the inner groove 11 and held in place. When the second steel sheet 4 is fed, the waste edge 5, the second steel sheet 4, and the release film 6 are fed at the same time. The second steel sheet 4 is arranged facing downwards so that the two second steel sheets 4 are fed at the same time and are reliably aligned with the positioning protrusion 14 through the alignment hole 61. This ensures that the inner end of the second steel sheet 4 and the hot melt adhesive 3 of the first steel sheet 2 are precisely aligned and the feeding is fast and accurate. The outer end of the second steel sheet 4 in the length direction is pressed onto the corresponding end of the upper surface of the tray 20, and then the hot melt adhesive is melted and fixed. After that, the tray 20 is removed to take out the assembled product.

[0031] The presence of the tray 20 allows it to be lifted upwards with one hand, thereby separating the product from the base plate 10, reducing the difficulty of picking up the product and improving assembly efficiency.

[0032] When the pallet 20 pulls the product, along with the waste edge 5 corresponding to the second steel sheet 4 and the release film 6, away from the bottom plate, the release film 6 pulls the waste edge 5 to discharge waste, thereby obtaining the product.

[0033] In practice, the lowering height of the lowering section 12 is equal to the thickness of the pallet 20. In the working state, the upper surface of the pallet 20 is flush with the upper surface of the base plate 10.

[0034] The base plate 10 is recessed on both sides of the middle part of the inner groove 11 along the length direction to form a detection and adjustment notch 15. When the central component 1 is observed to have a lateral protrusion on one side, the alignment is adjusted through the detection and adjustment notch 15, making the alignment simple and convenient.

[0035] In practice, the base plate 10 is made of aluminum alloy, which facilitates reliable heat transfer to the hot melt adhesive 3.

[0036] There are two positioning protrusions 14 on each end of the lowered surface 12; the two positioning protrusions 14 have a conical structure that tapers from bottom to top, which ensures that the tray 20 is easily and quickly aligned.

[0037] In practice, the tray 20 is made of FR4 material to ensure stable and reliable shape when heated.

[0038] In specific implementation, the inner groove 11 is recessed by 0.2-0.25mm relative to the upper surface of the base plate 20. After the central component 1 is embedded in the inner groove 11, the first steel sheet 2 does not protrude from the upper surface of the base plate 10, and ensures that the hot melt adhesive 3 has a accommodating space.

[0039] Its working principle is as follows: In the working state, the tray cover is installed on the base plate and assembled by aligning with the positioning holes and positioning protrusions. The central component of the product is positioned in the inner groove and held in place. Two second steel plates are simultaneously transferred to the inner end and aligned with the hot melt adhesive of the first steel plate, and are precisely positioned. The outer end of the second steel plate along its length is pressed onto the corresponding end of the upper surface of the tray. Then, the hot melt adhesive is melted and fixed. After that, the tray is removed to take out the assembled product. It reliably positions and adsorbs the central component, and makes the inner end of the second steel plate reliably aligned with the corresponding position of the first steel plate of the central component, thereby improving the positioning accuracy and assembly efficiency.
