Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 and 2, a thin-walled case fixing tool for protecting components includes a base plate 1, a plurality of dispensing holes 101 are formed in an upper surface of the base plate 1, the dispensing holes 101 are formed along an edge of a thin-walled case 3, and the thin-walled case 3 is fixed by injecting hot melt adhesive into the dispensing holes 101. This way of fixing does not require the application of external forces and does not lead to deformation of the thin-walled housing 3.

In order to inject hot melt adhesive without influencing the position of the thin-wall shell 3, a glue spraying hole 102 is punched on the side surface of the bottom plate 1, and the glue spraying hole 102 is communicated with the glue dispensing hole 101. I.e., the dispensing hole 101 leaks out on the upper surface of the base plate 1, and the glue spraying hole 102 is an inner hole (i.e., does not leak out on the upper surface of the base plate 1). When spraying the glue, the gun head of the hot melt glue gun extends into the glue spraying hole 102.

In this embodiment, the glue-spraying holes 102 are wide. In order to ensure that the thin-wall shell 3 is preliminarily placed on the bottom plate 1, a shallow groove pit matched with the bottom surface of the thin-wall shell 3 can be formed in the bottom plate 1, and the thin-wall shell 3 is preliminarily placed in the shallow groove pit.

In order to facilitate taking down the thin-wall housing 3 from the hot melt adhesive at the dispensing holes 101, in the present scheme, a plurality of alcohol grooves 103 are formed on the upper surface of the bottom plate 1, the dispensing holes 101 are located at the groove walls of the alcohol grooves 103, and one alcohol groove 103 corresponds to a plurality of dispensing holes 101. By introducing alcohol into the alcohol tank 103, the alcohol flows into the dispensing holes 101, thereby softening the hot melt adhesive.

In order to avoid thermal engineering to add alcohol and reduce workload, the upper surface and the lower surface of the plate 1 are respectively provided with a discharge bin 4 and a material receiving box 5, the discharge bin 4, the alcohol tank 103 and the material receiving box 5 are sequentially communicated, and the material receiving box 5 is communicated with the discharge bin 4 through a pipeline and a pump to form circulation. Namely, the alcohol can automatically circulate.

To promote the flow of alcohol, the alcohol tank 103 is inclined so that one end is high and the other end is low, and the end near the hopper 4 is high.

As shown in fig. 1 and 2, in order to prevent the alcohol tank 103 from being blocked by the hot melt adhesive sprayed from the hot melt adhesive gun, a baffle plate 2 is provided in each of the glue holes 101 in the alcohol tank 103. All there is the interval between the lateral wall of baffle 2 and alcohol groove 103, if the dynamics of spraying is too big promptly, then spray on baffle 2, but the alcohol groove 103 of baffle 2 back department still can keep unblocked, guarantees that alcohol circulation flows, guarantees that the hot melt adhesive can be softened.

In this embodiment, the upper end surface of the baffle plate 2 is flush with the upper surface of the bottom plate 1, or the upper end surface of the baffle plate 2 is lower than the upper surface of the bottom plate 1.

A switch valve is arranged on the discharging bin 4, and when the fixing work is carried out, alcohol is stored in the discharging bin 4.

The above examples only represent preferred embodiments, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
