Wherein the positioning assembly 10 is integrally mounted on the base plate 50.

The first guide hole 116 is communicated with the avoidance groove 115, the first press block 12 penetrates through the first guide hole 116, and a gap exists between the first press block 12 and the inner peripheral surface of the first guide hole 116, so that the first press block 12 can reciprocate in the first guide hole 116 along the third direction C.

The first press block 12 is applied with a buffering force in the third direction C through the first buffer 17, so that the first press block 12 has a buffering effect, and the first press block 12 can be slowly abutted against the end portion of the cover plate 200 under the buffering of the first buffer 17.

Referring to fig. 5, for example, the positioning member 11 further includes at least one second guiding hole 117 corresponding to the at least one pre-pressing member 21 one by one, the at least one second guiding hole 117 is disposed on the body 111 at intervals, the second guiding hole 117 penetrates through two surfaces of the body 111 opposite to each other in the first direction a and is communicated with the positioning slot 112, and the pre-pressing member 21 can penetrate through the second guiding hole 117 and move along the first direction a under the guiding of the second guiding hole 117.

The four corners of the third guiding hole 321 are arc-shaped, so that on one hand, the third guiding hole 321 is convenient to process on the guiding piece 32, and on the other hand, when the side pushing piece 31 moves in the third guiding hole 321, the corners of the side pushing piece 31 do not collide with the corner positions of the third guiding hole 321, and the side pushing piece 31 moves in the second direction B under the guiding of the third guiding hole 321 more smoothly.

Illustratively, the side pushing assembly 30 further includes a first mounting member 33 and a third buffer member 34, the first mounting member 33 is formed with a mounting hole 331, at least a portion of the third buffer member 34 is accommodated in the mounting hole 331, one end of the third buffer member 34 is fixed in the mounting hole 331, the other end of the third buffer member 34 is connected to the side pushing member 31, the third buffer member 34 is always in a compressed state, and the third buffer member 34 is used for applying a buffering force along the second direction B to the side pushing member 31.

The third buffer member 34 applies a buffer force along the second direction B to the supposition member, so that the side pushing member 31 has a buffer effect when moving along the second direction B, when the side pushing member 31 pushes the cover plate 200, the cover plate 200 is prevented from crushing the housing 300 or pushing the cover plate 200 through the opening of the housing 300, so that the side pushing member 31 can slowly push the cover plate 200 into the opening of the housing 300, and the assembly of the cover plate 200 and the housing 300 is completed.

The first mounting member 33 is connected to the guide member 32 and located at one side of the third guide hole 321 in the second direction B, and the first mounting member 33 is spaced apart from the positioning member 11 in the second direction B. The side pushing assembly 30 further comprises a fourth connecting member 35, the guide member 32 being connectable to the second driving member 42 via the fourth connecting member 35, the second driving member 42 driving the guide member 32 to move in the second direction B, wherein the first mounting member 33 is stationary with respect to the guide member 32, such that the third buffer member 34 connected between the side pushing member 31 and the first mounting member 33 is elastically deformed, such that the third buffer member 34 can apply a buffering force to the side pushing member 31 in the third direction C toward the cover plate 200 side.

In this application, when the pre-pressing piece 21 pushes the cover plate 200 to the opening of the housing 300, the cover plate 200 is slid into the opening from the side edge of the opening by matching with the acting force along the second direction B applied by the side pushing piece 31 to the cover plate 200, if the cover plate 200 is directly pushed into the housing 300 from the first direction a only through the pre-pressing piece 21, because the matching gap between the cover plate 200 and the inner surface of the housing 300 in the diffraction direction of the center of the housing 300 is smaller, when the cover plate 200 is directly pushed into the housing 300, the cover plate 200 will squeeze the housing 300 to deform to form a fold, and in this application, the cover plate 200 is pushed into the housing 300 by matching with the side pushing piece 31 through the pre-pressing piece 21, which is beneficial to improving the assembly yield of the cover plate 200 and the housing 300.

Referring to fig. 7 and 8, for example, the cover assembly mechanism 100 further includes a closing-in pressing assembly 60, and closing-in pressing assemblies 60 are mounted on two opposite sides of the positioning member 11 in the second direction B, and the closing-in pressing assembly 60 includes a second pressing block 61, where the second pressing block 61 is configured to apply a force along the first direction a to an end of the cover 200 in the first direction a.

Two binding off pressing assemblies 60 that are located the opposite both sides of locating component 10 are all installed on bottom plate 50, and binding off pressing assemblies 60 still includes second installed part 62, fifth connecting piece 63 and movable joint 64, and second installed part 62 is installed on the guide rail of bottom plate 50, and second installed part 62 is connected with movable joint 64 through fifth connecting piece 63.

The driving assembly 40 further includes a fourth driving member 44, where the fourth driving member 44 is connected to the second pressing block 61, and the fourth driving member 44 drives the second pressing block 61 to move in the first direction a, and two second pressing blocks 61 located on two opposite sides of the positioning assembly 10 in the second direction B press two opposite ends of the cover plate 200 in the second direction B, so that the cover plate 200 is flatly covered on the housing 300.

The first driving member 41, the second driving member 42, the third driving member 43, and the fourth driving member 44 of the present application may be cylinders, or may be motors.

In this application, the workflow of the cover plate assembly mechanism 100 is as follows:

after the cover plate 200 is received by the cover plate assembling mechanism 100, the cover plate 200 is adsorbed in the positioning groove 112 by vacuumizing the adsorption hole 114, and the cover plate 200 is propped against one side wall of the positioning groove 112 opposite to the first guide hole 116 in the third direction C through the first pressing block 12, at this time, the opposite sides of the cover plate 200 in the third direction C are positioned, so that the first pressing block 12 can be retracted, and the acting force of the first pressing block 12 on the cover plate 200 is cancelled; then, the cover plate assembly mechanism 100 is moved to a position where the housing 300 is located, and a small gap exists between the cover plate 200 and the housing 300 in the first direction a so that the cover plate 200 can move along the second direction B; next, the cover plate 200 is pushed to the opening of the housing 300 by the pre-pressing piece 21, the cover plate 200 is pushed into the housing 300 from the side edge of the housing 300 by the side pushing piece 31, and finally, two opposite end parts of the cover plate 200 in the second direction B are pressed by the second pressing piece 61, so that the assembly of the cover plate 200 and the housing 300 is completed.

The foregoing is a partial embodiment of the present application and it should be noted that, for a person skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
