[First Embodiment]

Referring to FIG. 4, the first embodiment of the present invention provides a hot melt device 100, which includes: an upper mold assembly 1, a plurality of elastic elements 2, a plurality of first hot melt columns 31, and a guide plate 4.

The upper mold assembly 1 includes a housing 11 and an upper template 12. The upper inner wall of the housing 11 has a plurality of guiding posts 113, and the upper template 12 has a plurality of through holes 121. The upper template 12 abuts against two opposite side walls 111 and 112 of the casing 11, and a cavity 10 is formed between the casing 11 and the upper template 12.

A plurality of elastic elements 2 are arranged in the cavity 10, and one end of each elastic element 2 is sleeved on each guide post 113 and connected to the upper inner wall 110 of the housing 11. Two adjacent elastic elements 2 are separated by a distance H, so that when a plurality of elastic elements 2 contact the upper surface of the guide plate, the plurality of elastic elements 2 are evenly distributed on the upper surface of the guide plate.

A plurality of first hot-melt pillars 31 are disposed in the cavity 10, and each first hot-melt pillar 31 is movably penetrated through each through hole 121. The guide plate 4 is movably arranged between the elastic element 2 and the plurality of first hot-melt columns 31, the upper surface 41 of the guide plate 4 is in contact with the other end of the plurality of elastic elements 2, and the lower surface of the guide plate 4 42 is in contact with a plurality of first hot-melt pillars 31. When the elastic element 2 contacts the upper surface 41 of the guide plate 4, a plurality of elastic elements 2 are evenly distributed on the upper surface 41 of the guide plate 4. It is worth mentioning that in the embodiment of the present invention, the elastic element 2 may be a spring made of spring steel, but the present invention is not limited.

Furthermore, in the present invention, the plurality of elastic elements 2 and the plurality of first hot-melt pillars 31 are separated by the guide plate 4, and this way is to prevent each elastic element 2 from directly contacting each of the first hot-melt pillars 31. (That is, the implementation type of the prior art). On the contrary, through the separation of the guide plate 4, the multiple elastic elements 2 can act together in an integrated form, rather than act independently in an individual form. The advantage is that even if one of the elastic elements 2 is deformed due to skew due to high temperature and rusting, the other elastic elements 2 can be activated, so the cooperation of any first hot melt column 31 is not affected. In the prior art, since each spring directly contacts each hot melt column, as long as any spring is skewed and deformed due to high temperature rust, its corresponding hot melt column will also lose its function and cause a jam. Therefore, the design of the hot-melting device 100 of the present invention can improve the problem of easy tilting of the spring of the independent spring hot-melt column.

Referring to FIG. 5, the first embodiment of the present invention provides a hot melt machine M, which includes a main body 6, a hot melt device 100 (as shown in FIG. 4 ), and a lower mold assembly 70. The main body 6 has an accommodating space 60 inside, and the hot melt device 100 and the lower mold assembly 70 are both arranged in the accommodating space 60. The lower mold assembly 2'is relatively disposed under the hot-melting device 100, and the lower mold assembly 70 is used to carry the first workpiece 71 and the second workpiece 72 having a plurality of welding parts 73.

The hot melt machine M further includes a pneumatic assembly 8 arranged in the accommodating space 60. The pneumatic assembly 8 includes a cylinder bearing 81 and a pressing plate 82, a plurality of sleeves 83, and a plurality of support columns 84. The sleeve 83 is movably sleeved on the support On the column 84, a plurality of sleeves 83 are connected to the pressure plate 82, and the cylinder bearing 81 is used to apply a downward pressure to the pressure plate 82, so that the pressure plate 82 is sleeved on the support column 84 through the sleeve 83 and moves along the support column 84.

In addition, the hot melt machine M further includes a heating assembly 91, a plurality of fixing members 92, a pressure sensing assembly 93, and a control module (not shown in the figure). The heating assembly 91 is arranged between the pressing plate 82 and the hot melt device 100. The heating component 91 is used to heat the hot melt device 100. A plurality of fixing members 92 fix the heating assembly 91 and the hot melt device 100 to the pressing plate 82. The pressure sensing assembly 93 is provided between the cylinder bearing 81 and the pressure plate 82. The control module is electrically connected to the pneumatic component 8, the heating component 91 and the pressure sensing component 93, and the control module includes a touch hole display panel 94 provided on the main body 6, allowing the user to control the pneumatic component 8 and the pneumatic component through the touch hole display panel 94 The operation of the heating element 91.

Next, the operation mode of the hot melt device 100 and the hot melt machine M will be described. Referring to FIG. 6, when the hot melt machine M is started, the hot melt device 100 will be heated to a working temperature through the heating assembly 91 first. The user can input a pressure setting value to the control module by operating the touch display panel 94. The control module outputs a control signal to the pneumatic assembly 8 according to the set value, so that the cylinder bearing 81 outputs a pressure to push the pressure plate 82 downward, and the pressure plate 82 drives the hot melt device 100 to move downward. The plurality of first hot-melting pillars 31 in the hot-melting device 100 are brought into contact with the welded portion 73 of the second workpiece 72 placed on the lower mold assembly 70.

When the thermal fusion device 100 moves downward, the plurality of first thermal fusion columns 31 touch the plurality of fusion joints 73, and the plurality of fusion joints 73 are heated and melted. Then, the first hot-melt column 31 presses the melted welding portion 73 with a preset pressure (that is, the above-mentioned pressure setting value) to contact the first workpiece 71 and the second workpiece 72, and then weld the first workpiece 71 and the second workpiece. Two workpieces 72, the first workpiece 71 and the second workpiece 72 are combined into a new workpiece.

When the first hot-melt column 31 is pressed against the workpieces (the first workpiece 71 and the second workpiece 72), a force will be transmitted back to the multiple elastic elements 2 in the elastic element 2, causing the multiple elastic elements 2 to deform. The restoring force generated by the deformation of each elastic element 2 is transmitted to the pressure sensing assembly 93. The pressure sensing component 93 senses the restoring force generated when the multiple elastic elements 2 of the elastic element 2 deform, and accordingly sends a pressure signal and feeds it back to the control module. After the control module receives the pressure signal, it converts the pressure signal into an output result and displays it on the touch display panel 94 for the user to make further confirmation.

Next, refer to FIG. 7, which is also a schematic diagram showing the pressing down of the hot melt machine and the hot melt device of the present invention. However, comparing FIGS. 6 and 7 shows that the horizontal position of the first workpiece 71 in FIG. 7 is higher than the horizontal position of the first workpiece 71 in FIG. 6. In other words, the pressing stroke of the thermal melting device 100 in FIG. 7 is shorter than the pressing stroke of the thermal melting device 100 in FIG. 6. The so-called stroke refers to the distance that the hot melt device 100 touches the workpiece when it is pressed down. Due to the design of the elastic element 2 and the guide plate 4 inside the hot melt device 100 in the present invention, the different deformations produced by the multiple elastic elements 2 for different pressing strokes can be utilized to achieve the same welding effect. Therefore, use There is no need to adjust the structure of the hot melt device 100 for different pressing strokes. In other words, the hot-melting device 100 and the hot-melting machine M of the present invention can adapt to various different hot pressing strokes and improve the hot pressing efficiency.

[Second Embodiment]

Referring to FIGS. 8 to 10, the difference between the second embodiment and the first embodiment is that the hot-melting device 100 (shown in FIG. 8) and the hot-melting machine M shown in the second embodiment further include a fixed column 5 and The second hot-melt column 32 is fixed in one of the through holes 121, the fixed column 5 is adjacent to the elastic element 2 and is arranged in the cavity 10, and one end of the fixed column 5 abuts against the upper part of the housing 11. On the wall 110, the other end of the fixing column 5 abuts against the second hot melt column 32. When the hot-melting device 100 fixed on the pressing plate 82 moves downward with the pressing plate 82, the first hot-melting column 31 and the second hot-melting column 32 press down on the plurality of welding parts 73 of the first workpiece 71 and the second workpiece 72, the plurality of welding parts 73 are further melted and the first work 71 and the second work 72 are welded. In other words, the hot melt device of the present invention can be simultaneously applied to the combination of two sets of workpieces with different strokes.
