Detailed Implementation

[0027] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0028] like Figures 1 to 8 As shown, this embodiment proposes a hot-melt device for automotive communication antenna housing, comprising:

[0029] The housing assembly 11 includes a support platform 12, a side plate 13 and a top plate 14, wherein the top plate 14 is fixed to the support platform 12 via the side plate 13.

[0030] The carrier 15 includes a fixing plate 16, limiting blocks 17, and positioning elements 18. The upper surface of the fixing plate 16 is fixed with the limiting blocks 17 and the positioning elements 18, and the lower surface of the fixing plate 16 is mounted on the support platform 12 via a translation mechanism 25. A product 30 is detachably mounted in the carrier 15. The edge of the product 30 has multiple positioning holes 19, which are fitted onto the positioning elements 18. Multiple limiting blocks 17 surround the outer periphery of the product 30, and each limiting block 17 is in contact with the product 30.

[0031] A hot riveting mechanism 20 is installed on the top plate 14 via a lifting mechanism 21. The hot riveting mechanism 20 is used to fix the riveting part 22 of the product 30.

[0032] This solution offers the advantage of rapid product 30 replacement. Simply align the positioning hole 19 of product 30 with the positioning element 18 and place product 30 onto the carrier 15 to install it. The limiting block 17 further improves the positioning accuracy of product 30. The combination of the limiting block 17 and the positioning element 18 significantly improves the installation accuracy of product 30, effectively preventing horizontal displacement. When the hot riveting mechanism 20 heats and softens the riveted portion 22 on product 30, it then presses and flattens the end of the riveted portion 22. This pressing does not cause significant impact to product 30, effectively preventing damage. Furthermore, the combined action of the limiting block 17 and the positioning element 18 prevents movement of product 30, thereby improving the riveting quality of product 30.

[0033] Furthermore, the positioning element 18 adopts a positioning pin or a positioning protrusion.

[0034] The translation mechanism 25 has a drive plate 45, which is used to fix the fixed plate 16.

[0035] As one embodiment of this example, the support platform 12 includes a support plate 23 and vertical plates 24. A plurality of vertical plates 24 are fixed to the lower end of the support plate 23, and an adjustment channel 44 is provided between the upper and lower surfaces of the support plate 23.

[0036] The translation mechanism 25 includes a driving member 26, which is fixed to the lower end face of the support plate 23 by a mounting base. The driving member 26 has an output part 27 that moves in a straight line. The output part 27 is fixed to a driving plate 45 by a connecting plate 28. The driving plate 45 is located above the support plate 23 and is fixedly connected to the fixing plate 16 of the carrier 15. The connecting plate 28 is slidably inserted into the adjustment channel 44.

[0037] In this solution, the drive component 26 can be a conventional cylinder; or it can be a conventional rodless cylinder or linear motor, which can reduce the space occupied by the drive component 26.

[0038] In one embodiment of this invention, the translation mechanism 25 further includes a slide rail assembly 29, through which the carrier 15 is mounted on the support plate 23. This design aims to improve the stability of the carrier 15 during movement.

[0039] The slide rail assembly 29 includes a guide rail and a slider, and is existing technology. The specific structure and connection relationship of the slide rail assembly 29 will not be described in detail.

[0040] The product 30 in this solution includes a housing 31 and a strip 32. The housing 31 has multiple riveting portions 22, and the strip 32 has riveting holes. The riveting portions 22 are used to pass through the riveting holes. The hot riveting mechanism 20 heats and softens the riveting portions 22 on the product 30, and then compresses the riveting portions 22 and flattens their ends. This significantly reduces the impact force of the riveting portions 22 on the housing 31, avoids cracks at the connection between the housing 31 and the riveting portions 22, and effectively improves product quality. The flattened portion of the riveting portion 22 blocks the riveting holes of the strip 32, thereby fixing the housing 31 and the strip 32.

[0041] In one embodiment of this invention, the lifting mechanism 21 includes a lifting plate 33, guide rods 34, and a pressing cylinder 35. Multiple guide rods 34 are fixed between the supporting plate 23 and the top plate 14. The pressing cylinder 35 is mounted on the top plate 14 and has a piston rod that moves vertically. The piston rod is connected to the lifting plate 33 via a transmission mechanism. The lower surface of the lifting plate 33 is used to mount the hot riveting mechanism 20.

[0042] This design improves the stability of the lifting plate 33's movement by using multiple guide rods 34. Furthermore, the piston rod of the downward-pressing cylinder 35 can be installed with the lifting plate 33 via a snap-fit ​​or fixed connection.

[0043] Furthermore, a return spring 36 is sleeved on the guide rod 34, and the return spring 36 is located between the lifting plate 33 and the supporting plate 23.

[0044] In one embodiment of this invention, the hot riveting mechanism 20 includes a pad 37, a mounting plate 38, a heating component 39, a heat insulation component 40, and hot riveting heads 41. The mounting plate 38 is fixed to the lower end of the lifting plate 33 by the pad 37. The heating component 39 is fixed to the lower end of the mounting plate 38 by the heat insulation component 40. A plurality of hot riveting heads 41 are installed at the lower end of the heating component 39. The hot riveting heads 41 are used to heat the riveting part 22 and to press the riveting part 22.

[0045] In this design, the heat transfer from the heating element 39 to the lifting plate 33 is reduced by setting up a pad 37, a mounting plate 38, and a heat insulation component 40, thus reducing some heat loss. In addition, the hot riveting head 41 can both soften and compress the riveting part 22, eliminating the need for additional extrusion parts, reducing the number of parts, and improving processing efficiency.

[0046] In one embodiment of this invention, a protective plate 42 is provided above the carrier 15. The protective plate 42 is fixed to the side plate 13, and a gap is provided between the protective plate 42 and the support platform 12 to provide clearance for the movement of the carrier 15. The protective plate 42 is used to isolate the processing area to prevent personnel from accidentally touching the parts in the processing area when the equipment is working.

[0047] The heat insulation component 40 is a heat insulation block or heat insulation plate. The heating component 39 is a heating plate in the prior art. The heating plate can be equipped with a heating resistor or an induction coil. It can use resistance heating or electromagnetic induction heating. For specific structure and principle, please refer to the prior art.

[0048] In this scheme, the position of the carrier 15 is adjusted by the translation mechanism 25. When the carrier 15 enters the processing area, the carrier 15 is located below the hot riveting mechanism 20. In the initial state, the carrier 15 is located in the loading area, which facilitates the loading and unloading of the product 30 in the carrier 15.

[0049] In addition, this solution also includes a temperature controller 43, which is existing technology and is used to control the heating temperature of the heating element 39.

[0050] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
