[0036] Surface assembly technology, also known as surface mount technology, is commonly used in the electronic assembly industry. When used for patch manufacturing, multi-layer patches need to be riveted and assembled.

[0037] In the related art, the hot rivet heads of the hot riveting tooling used for riveting are locked on a mounting plate by screws. The installation of multiple hot rivet heads is cumbersome and the installation efficiency is low. At the same time, the adjustability of the hot rivet heads is also poor.

[0038] The utility model provides a hot riveting tool 100.

[0039] Reference Figure 1 and Figure 2 , Figure 1 It is a side view structural schematic diagram of an embodiment of the hot riveting tool of the utility model; Figure 2 It is a three-dimensional structural schematic diagram of an embodiment of the riveting equipment of the utility model.

[0040] In the embodiment of the present utility model, the hot riveting tool 100 includes a base 10, a mounting member 30, a magnetic member 20 and a plurality of hot riveting heads 50. Figure 1 As shown, the mounting member 30 is detachably connected to the base 10 and encloses a cavity, and the magnetic attraction member 20 is disposed in the cavity. A plurality of hot riveting heads 50 are disposed on the side of the mounting member 30 facing away from the base 10, and each hot riveting head 50 is provided with a magnetic conductive portion 51, and the hot riveting head 50 is attached to the mounting member 30 through the magnetic attraction force of the magnetic conductive portion 51 and the magnetic attraction member 20.

[0041] The hot riveting tool 100 of the technical solution of the utility model includes a base 10, a magnetic attraction part 20, a mounting part 30 and a plurality of hot riveting heads 50. The mounting part 30 is detachably connected to the base 10 and encloses a cavity, and the magnetic attraction part 20 is arranged in the cavity. The hot riveting head 50 is arranged on the side of the mounting part 30 facing away from the base 10, and a magnetic conductive part 51 is provided at one end of the hot riveting head 50 connected to the mounting part 30. The magnetic conductive part 51 and the magnetic attraction part 20 are magnetically attracted to each other, so that the hot riveting head 50 is attached and installed on the mounting part 30 through the magnetic conductive part 51, which simplifies the installation steps and improves the installation efficiency. The magnetic attraction of the magnetic attraction part 20 to the magnetic conductive part 51 improves the installation stability of the hot riveting head 50 and the mounting part 30, and also makes the installation position of the hot riveting head 50 flexibly adjustable.

[0042] Optionally, the mounting member 30 is made of anti-magnetic material.

[0043] In this embodiment, the magnetic member 20 can be a magnet or a magnet that can generate a magnetic field. For example, the magnet is one of a samarium cobalt magnet, a neodymium iron boron magnet (strong magnet), a ferrite magnet, and an aluminum nickel cobalt magnet. The mounting member 30 is made of an antimagnetic material, so that the installation of the mounting member 30 will not affect the magnetic attraction between the magnetic conductive portion 51 of the riveted joint and the magnetic member 20, thereby improving the assembly stability of the mounting member 30 and the riveted joint.

[0044] The direction in which the hot riveting head 50 approaches or moves away from the riveting point is set as the up-down direction, and the up-down direction is the normal direction of the plane where the base 10 is located.

[0045] Furthermore, the mounting member 30 can be a non-magnetic metal plate or a hard plastic plate, which is light in weight and easy to disassemble. In practical applications, one substrate is provided with at least one mounting member 30, and the number of mounting members 30 can be set to multiple. Multiple hot riveting heads 50 can be installed on each mounting plate, and multiple mounting plates with hot riveting heads 50 installed thereon are spliced ​​and arranged along the length extension direction of the substrate, so as to flexibly adjust the installation position or installation number of the hot riveting heads 50.

[0046] like Figure 1 As shown, optionally, a mounting groove is provided on a side of the mounting member 30 facing away from the magnetic attraction member 20 corresponding to each hot riveting head 50 , and at least a portion of the magnetic conductive portion 51 is accommodated in the mounting groove.

[0047] In this embodiment, the mounting groove is recessed on the side of the mounting member 30 facing away from the magnetic attraction member 20. The number of mounting grooves may be equal to or greater than the number of thermal rivet heads 50. The mounting groove is used to accommodate at least part of the magnetic conductive portion 51 of the thermal rivet head 50, so that the thermal rivet head 50 can be limited and stopped in a direction other than parallel to the groove depth, thereby improving the assembly stability of the thermal rivet head 50 and the mounting member 30.

[0048] Optionally, along the thickness direction of the mounting member 30 , the mounting groove is a sunken groove.

[0049] In this embodiment, the depth direction of the mounting groove is the thickness direction of the mounting member 30, that is, the mounting groove is recessed in the mounting plate along the thickness direction of the mounting member 30. The mounting groove can be a sunken groove that does not penetrate the thickness of the mounting member 30. The mounting member 30 is an anti-magnetic body and the mounting member 30 does not have the function of shielding the magnet. The magnetic attraction of the magnetic attraction member 20 allows the hot rivet head 50 to be stably set in the mounting groove, and the groove bottom limits the force movement distance of the hot rivet head 50, so that the hot rivet head 50 is stably assembled on the mounting member 30.

[0050] Optionally, along the thickness direction of the mounting member 30, a mounting groove is set through the mounting member 30, and the mounting groove includes an avoidance section and a accommodating section arranged up and down, and the aperture of the avoidance section is smaller than the aperture of the accommodating section to form a step surface at the connection between the avoidance section and the accommodating section, and the accommodating section is used to accommodate the magnetic conductive part 51, and the end of the magnetic conductive part 51 is limited to the abutment on the step surface.

[0051] In this embodiment, the depth direction of the mounting groove is the thickness direction of the mounting member 30, that is, the mounting groove is recessed in the mounting plate along the thickness direction of the mounting member 30. The mounting groove can be the above-mentioned recessed groove or a hole-shaped groove that can penetrate the thickness direction of the mounting member 30.

[0052] Specifically, the installation groove includes an avoidance section and a accommodating section along the upper and lower parts. The avoidance section is used to avoid the pipeline structure connected to the hot rivet head 50, and the accommodating section is used to accommodate the magnetic conductive portion 51 of the hot rivet head 50. The aperture of the avoidance section is smaller than the aperture of the accommodating section to form a step surface at the connection between the avoidance section and the accommodating section, that is, the installation groove is small at the top and large at the bottom to limit the force movement stroke of the hot rivet head 50, and at the same time avoid the pipeline structure connected to the hot rivet head 50, so that the pipeline structure can be installed in the cavity, thereby improving the space utilization rate in the cavity.

[0053] Optionally, a limiting ring is provided on the outer periphery of the magnetic conductive portion 51 , and the limiting ring abuts against a notch of the installation slot.

[0054] In this embodiment, for the assembly of the mounting member 30 and the hot riveting head 50, a limiting ring may also be provided on the outer periphery of the magnetic conductive portion 51, and the limiting ring is provided adjacent to the lower position of the magnetic conductive portion 51. The mounting groove may be a sunken groove, or a through straight hole, or the above-mentioned stepped hole. Under the action of the magnetic attraction force, the magnetic conductive portion 51 extends into the mounting groove, and the limiting ring abuts against the outer peripheral wall of the notch of the mounting groove, which can not only limit the force movement distance of the hot riveting head 50, but also improve the contact surface between the hot riveting head 50 and the mounting member 30, ensuring that the hot riveting head 50 is accurately installed and has high installation stability.

[0055] Optionally, the shape of the slot opening of the installation slot is triangular, circular, square or polygonal; the outer contour of the magnetic conductive portion 51 is adapted to the shape of the slot opening of the installation slot.

[0056] In this embodiment, the function of the mounting groove is to fit and position the magnetic conductive part 51 of the hot rivet head 50. The outer contour of the cross section of the mounting groove can be larger than the outer contour of the cross-sectional area of ​​the magnetic conductive part 51, or the outer contour of the magnetic conductive part 51 can be adapted to the notch shape of the mounting groove.

[0057] The notch of the installation groove can be a regular circle or square, a symmetrical regular polygon, or an asymmetrical curve or polygon, such as an ellipse. The different shapes of the notch of the installation groove can be used to adjust the alignment position of the rivet points of the hot rivet head 50. When a hot rivet head 50 is provided with a corresponding number of riveting parts 52 corresponding to two or more rivet points, the installation grooves with different shapes can play a certain foolproof role, improve the assembly efficiency of the hot rivet head 50 and the mounting part 30, and the alignment accuracy of the one-to-one alignment of the riveting parts 52 and the rivet points.

[0058] Optionally, the magnetic member 20 is disposed on a side of the base 10 facing the mounting member 30 , and the magnetic member 20 is detachably connected to the base 10 .

[0059] In this embodiment, the cavity is a hollow cavity that is connected on all sides, and the mounting member 30 is detachably fixedly connected to the base on all sides to form the cavity. In the cavity, the magnetic member 20 is arranged close to the wall, and specifically, the magnetic member 20 is arranged on the side of the base 10 facing the mounting member 30. The magnetic member 20 is detachably connected to the base 10, so that the magnetic member 20 and the mounting member 30 are arranged at a distance and not in contact.

[0060] The non-contact setting of the magnetic component 20 and the mounting component 30 ensures that the heat used by the hot rivet head 50 to heat the rivet point will not be directly transmitted to the magnetic component 20 through the inner wall of the cavity, but will be directly diffused in the hollow cavity where the mounting component 30 is located outside the cavity to dissipate heat, thereby avoiding the influence of heat on the magnetic field, maintaining the magnetic attraction strength between the magnetic conductive portion 51 of the hot rivet head 50 and the magnetic component 20, and improving the assembly stability of the mounting component 30 and the hot rivet head 50.

[0061] Optionally, the hot riveting tool 100 further includes a heat insulation layer 60 , which is disposed on a side of the mounting component 30 facing the magnetic component 20 , and the magnetic component 20 and the heat insulation layer 60 are spaced apart.

[0062] In this embodiment, the thermal insulation layer 60 is arranged in the cavity and is located on the side of the mounting part 30 facing away from the hot rivet head 50, that is, the thermal insulation layer 60 is arranged on the side of the mounting part 30 facing the magnetic attraction part 20, and the magnetic attraction part 20 and the thermal insulation layer 60 are arranged at intervals, so that the heat can be diffused in the cavity that is connected on all sides, and the heat diffusion to the magnetic attraction part 20 and the base 10 located on the opposite side of the cavity can be reduced, thereby avoiding the influence of heat on the magnetic field, maintaining the magnetic attraction strength between the magnetic conductive part 51 of the hot rivet head 50 and the magnetic attraction part 20, and improving the assembly stability of the mounting part 30 and the hot rivet head 50.

[0063] Optionally, the laying area of ​​the heat insulation layer 60 at least covers the installation area of ​​the hot rivet head 50 .

[0064] In this embodiment, the heat insulation layer 60 is laid on the side of the mounting member 30 facing away from the hot rivet head 50, and is detachably connected to the mounting member 30, exemplarily by snap-fitting or fastening by an external member. The laying area of ​​the heat insulation layer 60 can cover the entire installation area of ​​the mounting member 30, or at least cover the installation area of ​​the hot rivet head 50, relatively isolating the heat diffused during the heating process of the hot rivet head 50, so that as little heat as possible is transmitted to the magnetic attraction member 20, thereby avoiding the influence of heat on the magnetic field.

[0065] Optionally, the heat insulation layer 60 is one of asbestos board, rock wool board, ceramic board or aerogel felt.

[0066] In this embodiment, the insulation layer 60 is an asbestos board, rock wool board, ceramic board or aerogel felt, or can be a mold insulation board, which has high mechanical properties, low thermal conductivity, fire resistance, high temperature resistance, waterproof and flame retardant characteristics, and is used to block heat transfer and improve the assembly stability of the mounting part 30 and the hot rivet head 50.

[0067] like Figure 2 As shown, the utility model also proposes a riveting device 900, which includes a frame 91 and a hot riveting tool 100. The specific structure of the hot riveting tool 100 refers to the above embodiment. Since the riveting device 900 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the hot riveting tool 100 is movably arranged on the frame 91.

[0068] In this embodiment, the riveting device 900 includes a frame 91 and a base 10, a driving mechanism 93, a mounting member 30 and a plurality of hot riveting heads 50 arranged on the frame 91. The plurality of hot riveting heads 50 are mounted on a mounting member 30, and the plurality of mounting members 30 are arranged in parallel with the plurality of hot riveting heads 50 mounted thereon so as to perform riveting on a plurality of hot rivets simultaneously. An operating table 92 is provided on the frame 91, which can transport and accommodate the product 70 to be riveted. The driving mechanism 93 is provided on the frame 91, and is used to drive the base 10, the mounting member 30 and the plurality of hot riveting heads 50 to move up or down synchronously, so as to approach the operating table 92 and perform hot riveting and pressing on the product 70 to be riveted on the operating table 92.

[0069] The mounting member 30 and the base 10 are detachably assembled, and the hot rivet head 50 and the mounting member 30 are detachably assembled, so that when the product 70 to be riveted is replaced, the number of the mounting member 30 and the hot rivet head 50 can be increased or decreased accordingly, or the installation position or number of the hot rivet head 50 and the mounting member 30 can be adjusted accordingly to improve versatility, or a new mounting member 30 and multiple hot rivet heads 50 installed thereon can be directly replaced to improve the flexibility of changing the hot riveting tool 100 when the hot riveting working conditions change.
