[0031] In order to solve the problems existing in existing automatic assembly mechanisms, such as the inability to meet the requirements of parallelism and strength of assembly, and the low versatility in assembling materials of different length specifications, which affects the production efficiency and quality of products, the present invention provides an automatic assembly mechanism and method, which provides a first positioning fixture and a second positioning fixture with adjustable relative positions, and places the materials to be assembled in the first positioning fixture and the second positioning fixture respectively, and then presses down and positions the second material through the cooperation of the Z-direction pressure supply mechanism and the Y-axis propulsion mechanism to position and assemble the first and second materials. At the same time, the position of the assembled first and second materials can be adjusted in combination with the left clamping mechanism and the right clamping mechanism to ensure the accuracy of product assembly.

[0032] To describe the structure of the automatic assembly mechanism and method of the present invention in detail, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Glue or other similar substances can be pre-set on the first material or the second material. Then, when the positions of the first material and the second material correspond, the pressure can be maintained for a certain period of time to ensure effective assembly between the two. In addition, the left clamping mechanism 3 and the right clamping mechanism 2 cooperate to clamp the assembled first material and the second material to the left and right, and correct the position of the first material and the second material to prevent the materials from tilting or slipping.

[0035] Specifically, Figure 2 shows a schematic structure of a product positioning mechanism according to an embodiment of the present invention; and Figure 3 and Figure 4 Schematic structures of a first positioning tool and a second positioning tool according to embodiments of the present invention are respectively shown.

[0036] like Figures 1 to 4 As shown together, in the automatic assembly mechanism of the embodiment of the present invention, the product positioning mechanism 1 includes a first positioning tool 11 and a second positioning tool 13, wherein the first positioning tool 11 includes a first base 111, a positioning block 116 arranged on the first base 111, a first sleeve 113 and a cover plate 115; wherein the first material is placed in the positioning block 116, and the cover plate 115 is used to flip around and cooperate with the corresponding first buckle 112 to press and position the first material.

[0037] Specifically, one end of the cover 115 can be movably connected to the first base 111 through a rotating shaft or other similar components. The other end of the cover 115 is provided with a first clip 112 that cooperates with the hook on the first substrate, which can be used to open or close the cover 115. A hand-held portion 114 is provided on the cover 115. When the cover 115 is opened, it can be used to place the first material or product, and when the cover 115 is closed, it can be used to press and position the first material.

[0039] Among them, the positioning assembly may include at least two positioning pins of different sizes (including a first positioning pin 123 and a second positioning pin 124) and a positioning magnet 125; the positioning pins cooperate with the positioning holes on the first sleeve 113 for positioning, and the positioning magnet 125 is used to assist in positioning the first sleeve 113 and the second base 122. Among them, the two positioning pins of different sizes can play an anti-mistake role and prevent them from being placed upside down. In addition, the same role can be achieved by controlling the polarity of the positioning magnet 125.

[0040] Specifically, the positioning base plate 126 is movably connected to the base plate 121 via a first slide rail 128. A front stop 135 and a rear stop 129 are provided on the base plate 121. The front stop 135 and the rear stop 129 are designed to accommodate materials of varying lengths. The ball plunger 130 is designed to provide a locking mechanism. When the ball plunger 130 reaches the rear stop 129, it is ejected, thereby providing a position limiter.

A first spring 132, which provides elastic force for the ball plunger 130, a ball plunger handle 131, and an operating handle 134 are also provided. When the Y-axis propulsion mechanism 5 pushes the ball plunger handle 131 outward, the ball plunger 130 is ejected by the first spring 132 and locked with a corresponding groove on the positioning base plate 126.

The movable clamping head 34 can be adjusted in position by the cooperation of the sliding pin 35 and the top screw 37; one end of the propulsion column 33 is limited by a limit pin 39, and the other end is elastically connected to the third base 31 through a third spring 32, and the movable clamping head 34 is movably connected to the propulsion column 33 through a fourth spring 38; the slider cylinder 310 is used to drive the propulsion column 33 and the movable clamping head 34 to correct the position of the assembled first material and the second material.

[0043] Among them, when the second material and the first material are assembled in place, the left clamping mechanism 3 and the right clamping mechanism 2 are activated, and the slider cylinder 310 drives the propulsion column 33 to move and the movable clamping head 34, so that the movable clamping head 34 is in contact with the assembled product. Since the head shape of the movable clamping head is consistent with the appearance of the product, the position can be calibrated by applying pressure. At the same time, the elastic feedback force is given by the third spring 32 and the fourth spring 38 to repeat the positioning and correction of the assembled product. After the action is completed, the slider cylinder 310 retracts, and the third spring 32 and the fourth spring 38 rebound.

[0044] In addition, the right clamping mechanism 2 and the left clamping mechanism 3 have the same structure and are symmetrically distributed with respect to the product positioning mechanism 1 , and the structure of the right clamping mechanism 2 will not be described in detail here.
