[0031] The utility model provides a device for assembling a spring.

[0032] like Figures 1 to 4 As shown, in one embodiment of the utility model, the device for assembling springs includes a feeding assembly 100, a material dividing assembly 200, and a transfer assembly assembly. A plurality of springs 400 to be assembled are stored in the feeding assembly 100, and are transported one by one to the material dividing assembly 200 through the feeding assembly 100, and then the springs 400 are transferred to the main parts of the product through the transfer assembly assembly for assembly. In this embodiment, the feeding assembly 100, the material dividing assembly 200, and the transfer assembly assembly are all arranged on one side of the conveying device, and the main parts of the product can be conveyed forward by the conveying device.

[0033] like Figure 1 and 2 As shown, the feeding assembly 100 includes a first mounting frame 110, a soundproof shell 120, a vibration plate 130, a straight vibrator and a feeding track 140. The soundproof shell 120 is arranged on the first mounting frame 110, and the vibration plate 130 and the straight vibrator are both arranged in the soundproof shell 120. The output end of the feeding track 140 extends out of the soundproof shell 120 and is connected to the material distribution assembly 200. Specifically, a plurality of springs 400 to be assembled are accommodated in the vibration plate 130, the output end of the vibration plate 130 is connected to the input end of the feeding track 140, the output end of the straight vibrator is connected to the feeding track 140, and the spring 400 is transported forward to the material distribution assembly 200 along the feeding track 140 through the vibration plate 130 and the straight vibrator.

[0034] like Figure 1 , 2 As shown in Figures 3 and 4, the material distribution assembly 200 specifically includes a second mounting frame 210, a rotating power source 220, a rotating block 230, a containing box 240, a first detection member 250, a second detection member 260, and a lifting cylinder (not shown in the figure). In this embodiment, the rotating power source 220 is installed at the rear of the second mounting frame 210, and the rotating block 230 and the containing box 240 are both arranged in front of the second mounting frame 210, the first detection member 250 is arranged on one side of the upper part of the rotating block 230, the lifting cylinder is arranged in front of the second mounting frame 210, and the second detection member 260 is connected to the output end of the lifting cylinder.

[0035] Specifically, the rotating block 230 includes four material distribution holes 2301, which are evenly arranged along the circumference of the rotating block 230. The above-mentioned rotating power source 220 is used to drive the rotating block 230 to rotate, and the output end of the above-mentioned feeding track 140 can be connected to the material distribution hole 2301 rotated to the front thereof. Further, the material distribution hole 2301 includes a radial section 23011 and a vertical section 23012, and the radial section 23011 and the vertical section 23012 are perpendicular to each other and L-shaped. After the material distribution hole 2301 rotates to the front of the feeding track 140, the radial section 23011 can be connected to the output end of the feeding track 140. When the spring 400 moves along the feeding track 140 to the radial section 23011 of the material distribution hole 2301, the upper end of the spring 400 is located outside the radial section 23011, and the lower end is located within the cross-sectional range of the vertical section 23012.

[0036] In this embodiment, when the spring 400 is transported forward along the feeding track 140, the second detection member 260 can detect the spring 400 in the dividing hole 2301 through the vertical section 23012 to identify the position of the spring 400 in the radial section 23011 of the dividing hole 2301. When the dividing hole 2301 connected to the feeding track 140 rotates ninety degrees along with the rotating block 230, the dividing hole 2301 will move to the front of the first detection member 250. At this time, the first detection member 250 can detect the radial section 23011 of the dividing hole 2301 to identify whether the dividing hole 2301 contains the spring 400 to be assembled. Furthermore, the above-mentioned receiving box 240 is arranged below the rotating block 230, and the radial section 23011 of the dividing hole 2301 can be rotated to the top of the receiving box 240 and aligned with the receiving box 240. If the spring 400 in the dividing hole 2301 is not taken by the spring taking mechanism 320, it will fall into the receiving box 240 for workers to recover.

[0037] It is worth noting that the above-mentioned rotating power source 220 can specifically be a motor or a rotating cylinder, and the first detection component 250 and the second detection component 260 can specifically be reflective optical fibers. Since the rotating power source 220 and the first detection component 250 and the second detection component 260, which are specifically reflective optical fibers, are mature existing technologies, they will not be repeated in this embodiment.

[0038] like Figure 1 , 2 As shown in Figure 4, the transfer assembly assembly includes a four-axis robot 300 and a spring removal mechanism 320, and the spring removal mechanism 320 is arranged at the end of the four-axis robot 300. Specifically, the spring removal mechanism 320 includes a first cylinder mounting plate and a second clamping portion, the first cylinder mounting plate includes a vertical mounting plate and a horizontal mounting plate, the vertical mounting plate is perpendicular to the horizontal mounting plate and is L-shaped, the first clamping claw cylinder 3205 is installed on the vertical mounting plate, and the second clamping portion is installed on the horizontal mounting plate. Furthermore, the second clamping part includes a vertical telescopic cylinder 3201, a second cylinder mounting plate 3202, a transverse telescopic cylinder 3203, a third cylinder mounting plate 3204 and a second clamping claw cylinder 3206, wherein the vertical telescopic cylinder 3201 is installed below the transverse mounting plate, the second cylinder mounting plate 3202 and the transverse telescopic cylinder 3203 are installed at the output end of the vertical telescopic cylinder 3201, and the third cylinder mounting plate 3204 and the second clamping claw cylinder 3206 are installed at the output end of the transverse telescopic cylinder 3203.

[0039] In this embodiment, the first clamping cylinder 3205 includes a first clamping finger 32051, and the second clamping cylinder 3206 includes a second clamping finger 32061. In the process of transferring the spring 400 from the material distribution hole 2301 to the main parts of the product for assembly operation by transferring the assembly component, the first clamping cylinder 3205 first clamps the upper end of the spring 400 through the first clamping finger 32051, and then the second clamping cylinder 3206 is driven by the vertical telescopic cylinder 3201 and the horizontal telescopic cylinder 3203 to move relative to the first clamping cylinder 3205, and clamps the lower end of the spring 400 through the second clamping finger 32061, thereby compressing the spring 400. In the process of the first clamping cylinder 3205 and the second clamping cylinder 3206 clamping and compressing the spring 400, the spring 400 can be transferred from the material distribution component 200 to the main parts of the product by the four-axis robot 300 for assembly operation. It is worth noting that the first clamping jaw cylinder 3205 and the second clamping jaw cylinder 3206 are both mature existing technologies and will not be described in detail in this embodiment.

[0040] Specifically, the working principle and process of the utility model are:

[0041] By providing a feeding component, a material dividing component and a transfer assembly component, the degree of automation of spring assembly can be improved, thereby improving the assembly efficiency of the spring.

[0042] The spring in the vibration plate can be transported forward to the radial section of the distribution hole along the feeding track through the vibration plate and the straight vibrator. After the spring is transported forward to the radial section of the distribution hole along the feeding track, the upper end of the spring is located outside the radial section, and the lower end is located within the cross-sectional range of the vertical section. The spring then rotates ninety degrees with the rotating block, thereby changing from a horizontal state to a vertical state. When the spring changes to the vertical state, the first clamping cylinder first clamps the upper end of the spring through the first clamping finger, and then the second clamping cylinder is driven by the vertical telescopic cylinder and the horizontal telescopic cylinder to cause displacement relative to the first clamping cylinder, and the lower end of the spring is clamped by the second clamping finger, thereby compressing the spring. In the process of the first clamping cylinder and the second clamping cylinder clamping and compressing the spring, the spring can be transferred from the distribution assembly to the main components of the product through the four-axis robot for assembly operations.

[0043] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
