Description

Technical Field

[0001] The utility model relates to the technical field of metal substrates, in particular to a metal substrate heater. Background Art

[0002] The substrate is the basic material for manufacturing PCB. Generally speaking, the substrate is a copper-clad laminate. In the manufacturing of single-sided and double-sided printed boards, hole processing, chemical copper plating, electroplating copper, etching and other processing are selectively performed on the substrate material - copper-clad laminate to obtain the required circuit pattern. The manufacturing of another type of multi-layer printed circuit board is also based on the inner core thin copper-clad laminate as the base. The conductive pattern layer and the prepreg are alternately laminated and bonded together at one time to form more than three layers of conductive pattern layer interconnection. It has three functions of conduction, insulation and support.

[0003] For example, the utility model with application number 201320108448.6 discloses a metal substrate heater, which includes a metal substrate circuit board and a heating wire forming a loop, wherein the metal substrate circuit board includes a metal substrate, an insulating thermally conductive film and a copper foil stacked up and down, wherein the insulating thermally conductive film is located between the metal substrate and the copper foil, and the metal substrate and the copper foil are insulated and separated by the insulating thermally conductive film, and the fusible metal wire is connected in series between the heating wires, and a constant temperature function is provided through the metal substrate circuit board. When the temperature is too high, the fusible metal wire melts, thereby disconnecting the loop formed by the heating wire, thereby achieving over-temperature protection.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] During the use of existing heaters, the metal substrate inside the heater is usually in a completely static state during the heating process, so uneven heating is likely to occur during the heating process. At the same time, due to high-temperature heating, the high temperature inside the heater box is likely to cause injuries.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a metal substrate heater is proposed. Utility Model Content

[0024] The following will be combined with the attached Figures 1 to 4The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a fixing fixture for steel pipe perforation processing through improvement. Figure 1-Figure 4 As shown, it includes a moving platform 1, a heater box 2 is fixedly installed at the top center of the moving platform 1, a rotating motor 3 is installed at the top center of the heater box 2, a limit ring 4 is fixed at the top of the inner cavity of the heater box 2, a rotating ring 5 is embedded at the bottom of the limit ring 4, and a clamping plate 6 is installed at the bottom of the rotating ring 5; a clamping mechanism for clamping the metal substrate is provided at the bottom of the clamping plate 6; and a circulation component for circulating the hot air inside the heater box 2 is installed at both ends of the inner cavity of the heater box 2. A rotating shaft is provided at the power output end of the rotating motor 3, a rotating gear 7 is fixedly connected to the bottom of the rotating shaft, and a linkage gear 8 is meshed at one end of the rotating gear 7, and a rotating gear ring 9 is fixedly connected to the inner wall of the rotating ring 5. The top of the linkage gear 8 is rotatably connected to the top of the inner cavity of the heater box 2, and the clamping plate 6 forms a rotating structure through the rotating gear 7, the linkage gear 8 and the rotating gear ring 9.

[0026] In this embodiment: during the heating process, the substrate body 15 is located at the center of the inner cavity of the heater box 2, and the rotating motor 3 is started. The rotating shaft and the rotating gear 7 are driven to rotate by the rotating motor 3, and the rotating ring 5 is driven to rotate through the meshing structure between the rotating gear 7 and the linkage gear 8 and the rotating gear ring 9. The rotating ring 5 is rotationally connected to the heater box 2 through the limit ring 4, and the rotating ring 5 and the clamping plate 6 are fixedly connected. Therefore, the rotation of the rotating ring 5 can drive the clamping plate 6 to rotate, thereby driving the substrate body 15 to rotate, so that the substrate body 15 can be heated evenly.

[0027] In the first embodiment, since the substrate body 15 needs to rotate during the heating process, it is easy to be dislocated due to the influence of the movement. The specific operation is as follows:

[0028] like Figure 3 and Figure 4As shown, the clamping mechanism includes a spring pin 10, which is equidistantly distributed at the bottom of the clamping plate 6. The bottom of the spring pin 10 is fixedly connected to a clamping buckle 11, and the bottom of the clamping buckle 11 is rotatably connected to a clamping roller 12. A moving plate 13 is installed below the inner cavity of the heater box 2, and the four corners of the bottom of the moving plate 13 are rotatably connected to moving wheels 14. The top of the moving plate 13 and the opposite side of the bottom of the clamping plate 6 have the same structure. The moving plate 13 and the opposite side of the clamping plate 6 are equidistantly distributed with a base plate body 15. A traction ring 23 is fixedly connected at the center of one end of the moving plate 13, and both ends of the opposite side of the moving plate 13 are hinged with a lifting frame 24, and a bidirectional cylinder 25 is fixedly connected at the center of the opposite side of the lifting frame 24. The interior of both ends of the heater box 2 is rotatably connected to a sealing door 20, and an observation window 21 is fixed inside the sealing door 20. The interior of the two ends of the top of the moving platform 1 is provided with a limited position rail 22.

[0029] In this embodiment: before heating, the substrate body 15 to be heated is clamped and fixed by the clamping roller 12 arranged on the top of the moving plate 13, and the position of the moving plate 13 is pulled and moved by the traction ring 23 and the matching hook and other devices until it moves to the center of the inner cavity of the heater box 2, and the two-way cylinder 25 is started. The position of the substrate body 15 is driven to rise through the action of the two-way cylinder 25 and the lifting frame 24, and the clamping roller 12 at the bottom of the clamping plate 6 cooperates with the clamping roller 12 at the top of the moving plate 13 to fix the substrate body 15 from the upper and lower ends of the substrate body 15;

[0030] In the previous embodiment, since the heat in the inner cavity of the heater box 2 is uneven, there is uneven heating. The specific operation is as follows:

[0031] like Figure 2 and Figure 3 As shown, the circulation component includes a heating device 16, which is fixedly installed on one side of the inner cavity of the heater box 2, and suction fans 17 are installed at both ends above the other side of the inner cavity of the heater box 2, and hair dryers 18 are installed at both ends below the other side of the inner cavity of the heater box 2. The suction fan 17 and the hair dryer 18 are fixedly connected to the air outlet 19 at one end close to the center of the inner cavity of the heater box 2.

[0032] In the present embodiment: heat is provided to the inside of the heater box 2 by the heating device 16 for heating the substrate body 15. Due to the rising characteristic of hot air, the suction fan 17 is started to absorb the hot air above the inner cavity of the heater box 2 and transfer it to the inside of the hair dryer 18, and then blown out through the air outlet 19. Such operation can transfer the hot air, so that the heat inside the heater box 2 can be evenly distributed, thereby ensuring the heating effect.
