Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] like Figure 1-6 As shown in the figure, the roller slide suitable for automated assembly described in this embodiment of the present invention includes a base 100, a roller 200, a side cover 300, and a plug 400.

[0030] The upper surface of the base 100 is provided with a groove 101 for mounting the roller 200. The groove 101 contains pre-positioning slots 102 arranged in an array along the length of the base 100. The upper and lower ends of the left and right outer surfaces 103 of the base 100 are respectively provided with an upper guide surface 104 and a lower guide surface 105. The upper and lower guide surfaces 104 and 105 are inclined surfaces. The two upper guide surfaces 104 are connected to the upper surfaces of the left and right ends of the base 100, respectively, and the two lower guide surfaces 105 are connected to the upper surfaces of the base 100. The lower surfaces of the left and right ends are connected. The outer surfaces 103 on the left and right sides of the base 100 are vertical planes. The angle between the inclined surface and the vertical plane is 30° to 60°, preferably 45°. Of course, the upper guide surface 104 and the lower guide surface 105 can also be arc surfaces. The side cover 300 includes two (left and right side covers). One side surface of the side cover 300 (the side surface facing the base 100) is provided with a slot 301. The slot 301 extends along the length of the side cover 300 and extends to the front and rear ends of the side cover 300.

[0031] In the automated assembly of the roller slide of this utility model, the rollers 200 are first arranged in an array along the length of the base 100 in the groove 101, and are assembled one-to-one on the pre-positioning groove 102; then, the two side covers 300 are directly pressed onto the left and right sides of the base 100, respectively. The left and right ends of the base 100 are respectively located in the slots 301 of the two side covers 300. During this process, the upper groove edge 302 and the lower groove edge 303 of the slot 301 slide and deform along the upper guide surface 104 and the lower guide surface 105, respectively, until they respectively fasten the upper and lower surfaces of the left and right ends of the base 100. The upper groove edge 302 and the lower groove edge 303 both extend horizontally toward the base 100 and are parallel to each other. Preferably, the lower groove edge 302 and the lower groove edge 303 extend horizontally toward the base 100 and are parallel to each other. The length of 303 is greater than the length of the upper groove edge 302. During the assembly process, the lower groove edge 303 first slides and deforms along the lower guide surface 105 and slides to the lower surface of the base 100. Then, the upper groove edge 302 slides and deforms along the upper guide surface 104 and slides to the upper surface of the base 100. Finally, the upper groove edge 302 and the lower groove edge 303 slide completely to the upper and lower surfaces of the base 100 at the same time, restore and clamp the left and right ends of the base 100. This avoids the problem of damage to the base 100 caused by the large pressing force required when the side cover 300 is pressed onto the base 100 because the upper groove edge 302 and the lower groove edge 303 touch the upper guide surface 104 and the lower guide surface 105 at the same time. This is conducive to realizing the automated assembly of the side cover 300 and the base 100.

[0032] The plug 400 of the roller slide described in this utility model is detachably assembled at both ends of the base 100. Specifically, the plug 400 is disposed at both ends of the roller slide and is fixedly fastened and riveted by the side cover 300. Figure 1 , Figure 2 , Figure 4 Of course, the plug 400 can also be integrally formed on both the front and rear ends of the base 100, such as... Figure 5 and Figure 6 .

[0033] Compared with the prior art, the roller slide of this utility model adopts a structure in which a prepositioning groove 102 is set in the base 100, and an upper guide surface 104 and a lower guide surface 105 are set. This meets the production requirements of automated assembly, improves product quality, avoids the quality problems of manual assembly, and ensures high product assembly consistency and high yield. On the other hand, it improves the assembly efficiency of the roller slide and significantly shortens the product production cycle.

[0034] For example Figure 1-4 As shown, in a preferred embodiment of this utility model, the bottom surface of the base 100 is provided with recessed platforms 106 at both ends. The recessed platforms 106 extend along the length direction of the base 100 and are provided with strip-shaped recesses 107 extending along the length direction of the base 100. At the same time, the lower guide surface 105 is connected to the recessed platforms 106. The inner surface of the lower groove edge 303 is provided with a protruding rib 304 extending along the length direction of the side cover 300. The lower groove edge 303 can slide along the lower guide surface 105 to the recessed platform 106, and the protruding rib 304 is engaged in the strip-shaped recesses 107. The recessed platforms 106 effectively limit the assembly position of the lower groove edge 303 (side cover 300), ensuring that the protruding rib 304 can be accurately engaged in the strip-shaped recesses 107 during automated assembly.

[0035] like Figure 1 As shown in Figures 2 and 4, in another preferred embodiment of this utility model, each pre-positioning groove 102 includes a shaft pre-positioning slot 110 provided on the left and right groove walls 109 of the groove 101, and a shaft pre-positioning cavity formed by two adjacent protruding limiting strips 108 provided on the bottom of the groove 101; wherein, the shaft pre-positioning slot 110 extends to the upper surface and left and right outer surfaces of the base 100, dividing the upper guide surface 104 into multiple segments, which is conducive to the automatic assembly of the rollers 200 from top to bottom into each pre-positioning groove 102, and also reduces the friction between the upper groove edge 302 of the side cover 300 and the upper guide surface 104, which is conducive to the automatic assembly of the side cover 300.

[0036] In addition, the upper groove edge (302) and lower groove edge 303 of one of the side covers 300 of the roller slide described in this utility model extend horizontally in a direction away from the base 100 to form a reinforcing rib 305; the outer surface of the other side cover 300 protrudes outward to form a reinforcing strip 306. On the one hand, this improves the strength of the side cover 300 and is conducive to automated assembly. On the other hand, the reinforcing strip 306 can be inserted between the two reinforcing ribs 305 to realize the connection of two adjacent roller slides.

[0037] Of course, the upper groove edge 302 and the lower groove edge 303 of this utility model extend horizontally in the direction away from the base 100 to form a reinforcing rib 305, which can also improve the strength of the side cover 300 and is beneficial to automated assembly.

[0038] like Figure 5 and Figure 6 As shown, the inner surface of the upper groove edge 302 of the side cover 300 of this utility model is provided with a hook 307. When the side cover 300 is pressed onto the base 100, the hook 307 hooks onto the upper surface of the base 100. Specifically, the hook 307 can be a rib extending along the length of the side cover 300. The upper surface of the base 100 is provided with a locking position 111. When the side cover 300 is pressed onto the base 100, the hook 307 (rib) is locked in the locking position 111 and hooks onto the upper surface of the base 100, which improves the assembly strength between the side cover 300 and the base 100, making the assembly stable and reliable. Moreover, by setting this rib, the overall strength of the side cover 300 is also enhanced, which is more conducive to automated production.

[0039] Of course, the hook 307 can hook the plug 400 while hooking the upper surface of the base 100, or it can hook only the plug 400; and in order to further adapt to automated production, the hook 307 (protruding rib) of the upper groove edge 302 and the protruding rib 304 of the lower groove edge 303 facing the base 100 are arc surfaces or inclined surfaces.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
