In this embodiment, the component 103 to be attached may be an earpiece decoration, a camera, a battery, or the like.

The gum activation device includes a base 2, a let-down plate 3, and a hold-down assembly 4. The top of the base 2 is fixedly provided with a jacking block 201. The piece placing plate 3 is located above the base 2 and is arranged in a manner of sliding up and down relative to the base 2, a piece placing station 301 for placing the gum component 1 to be activated is arranged on the upper surface of the piece placing plate 3, a through groove 302 which is through up and down is arranged in the piece placing station 301, and the jacking block 201 is located in the through groove 302 and is connected with the through groove 302 in a manner of sliding up and down. The pressing component 4 is located above the workpiece placing plate 3 and is used for pressing the gum component 1 located on the workpiece placing position 301 downwards, so that the pressing block 201 upwards abuts against the gum component 1 located in the workpiece placing position 301.

It can be understood that, when the gum activating operation is required, the gum assembly 1 is placed on the piece placing station 301, then the pressing assembly 4 moves downwards relative to the base 2 to press the gum assembly 1, after the pressing assembly 4 touches the gum assembly 1, the piece placing plate 3 moves downwards relative to the base 2, the jacking block 201 slides upwards relative to the piece placing plate 3 along the through groove 302, and finally, under the pressing action of the pressing mechanism 402, the jacking block 201 and the pressing mechanism 402 press the gum assembly 1 from the upper side and the lower side of the gum assembly 1, and the gum assembly 1 is activated. It is understood that the pressing mechanism 402 can realize the mechanized operation of the activation of the adhesive backing, and the pressing force when the adhesive backing 102 is activated can be effectively controlled by only controlling the pressing stroke of the pressing mechanism 402. Therefore, the gum activation equipment that this embodiment provided can realize the mechanized operation of gum activation, has the advantage that production efficiency is higher and extrusion strength is controllable.

Optionally, the gum activating device further comprises an elastic buffer mechanism 5 and a guide post 6. The elastic buffer mechanism 5 is located between the base 2 and the piece placing plate 3 and used for driving the piece placing plate 3 to slide upwards relative to the base 2. The guide post 6 is positioned between the base 2 and the piece placing plate 3, the lower end of the guide post is fixedly connected with the base 2, and the upper end of the guide post is connected with the piece placing plate 3 in a vertical sliding mode.

It can be understood that when the gum activation operation needs to be carried out, the pushing assembly 4 moves downwards to extrude the gum assembly 1, after the pushing assembly 4 touches the gum assembly 1, the piece placing plate 3 moves downwards relative to the base 2, the elastic buffer mechanism 5 is extruded, and provides buffer for sudden descending of the piece placing plate 3, so that the gum assembly 1 is prevented from being damaged by too large impact of the pushing mechanism 402 on the gum assembly 1. The guide post 6 plays a guiding role in the up-and-down sliding of the workpiece placing plate 3, and the horizontal deviation of the workpiece placing plate 3 in the up-and-down sliding process is avoided.

In this embodiment, the elastic buffer mechanism 5 is a single-head spring column, the single-head spring column is vertically arranged upwards, the non-telescopic end of the single-head spring column is fixed at the top of the base 2, and the telescopic end of the single-head spring column is located below the piece placing plate 3. In some other embodiments, the elastic buffer mechanism 5 is a compression spring, a double-headed spring column, or a telescopic rod.

When the elastic buffer mechanism 5 drives the piece placing plate 3 to slide upwards to the limit position, the upper surface of the tightening block 201 is located in the through groove 302.

It can be understood that, generally, the size of the casing 101 is larger than that of the part 103 to be pasted, so the size of the back adhesive 102 only needs to be matched with the part 103 to be pasted, and when the pressing activation is performed, the pressing can be performed only on the back adhesive 102, so as to avoid damaging or scratching the rest parts of the casing 101. Further, when the elastic buffer mechanism 5 jacks up the placing plate 3, the upper end face of the jacking block 201 retracts into the through groove 302, so that the situation that the jacking block 201 scrapes the gum component 1 when the gum component 1 is placed into the placing station 301 can be avoided.

In this embodiment, a plurality of limiting blocks are fixedly arranged on the upper surface of the piece placing plate 3, and all the limiting blocks enclose the piece placing station 301. In some other embodiments, a concave positioning groove may be disposed on the upper surface of the piece placing plate 3, and the positioning groove is used as the piece placing station 301 for placing the adhesive-backed component 1.

Optionally, the pressing assembly 4 includes a pressing plate 401 located right above the workpiece placing plate 3, and a pressing mechanism 402 having a driving end fixedly connected to the pressing plate 401, and the pressing mechanism 402 is configured to drive the pressing plate 401 to move up and down relative to the base 2.

It is understood that the depressing stroke of the depressing plate 401 can be controlled as long as the retracting stroke or the number of rotations of the depressing mechanism 402 is controlled.

In this embodiment, a timer is built in the control device of the gum activating device, and the timer is electrically connected to the pressing mechanism 402 through a control circuit. Specifically, the timer is used to record the time of pressing the adhesive-backed component 1, and when the pressing time reaches a preset time, for example, 3s, the pressing component 4 is automatically lifted upwards.

The working process of the gum activating device provided by the embodiment is as follows:

firstly, referring to fig. 2 and 3, the elastic buffer mechanism 5 jacks up the workpiece placing plate 3, and the upper end surface of the jacking block 201 retracts into the through groove 302; the lower pressing plate 401 is positioned above the workpiece placing plate 3, and an operation space is reserved between the lower pressing plate and the workpiece placing plate 3;

secondly, placing the gum component 1 on a workpiece placing station 301;

starting clicking, referring to fig. 4, the pressing mechanism 402 drives the pressing plate 401 to move downward relative to the base 2, and after the pressing plate 401 touches the gum component 1, the piece placing plate 3 moves downward relative to the base 2 and presses the elastic buffer mechanism 5 downward;
