The assembly table 1 rotates counterclockwise during operation, and performs terminal assembly, spring assembly, product detection, and product discharge in sequence.

[0041] The structure of the assembly platform 1 is as follows Figure 3 As shown, eight assembly molds 101 are provided on the assembly table 1, and the structure of each assembly mold 101 is as follows. Figure 4 , Figure 5 As shown, the front end is provided with a terminal slot 101a and a spring extrusion groove 101b which are connected to each other, and the rear end is provided with a push rod 101c which can extend into the terminal slot 101a. The terminal slot 101a is used to insert the terminal a, the spring extrusion groove 101b is used to squeeze the spring b to produce deformation, so as to facilitate pushing into the terminal a for assembly, and the push rod 101c is used to push the assembled product out of the mold.

[0042] Eight assembly molds 101 are equiangularly distributed on the outer edge of the assembly platform 1 , and a guide column 102 is disposed behind each assembly mold 101 on the assembly platform 1 .

[0043] The structure of the terminal assembly mechanism 2 is as follows Figure 6 As shown, it mainly includes a terminal vibration loading tray 201, a terminal discharge track 202 connected to the terminal vibration loading tray 201, and a terminal feeding slide 203 driven by a first cylinder 204 and slidably arranged at the output end of the terminal discharge track 202. The terminal feeding slide 203 is provided with a through groove 203a for receiving the terminal a output by the terminal discharge track 202. The specific setting position of the through groove 203a is shown in FIG. Figure 8 As shown, a blocking plate 205 for closing the penetration slot 203a is provided on one side of the terminal feeding slide 203 away from the terminal discharging track 202. A terminal pushing rod 206 driven by a second cylinder 207 is also provided at the front end of the terminal feeding slide 203.

[0044] When the terminal assembly mechanism 2 is working, the terminal vibration loading tray 201 outputs the terminal a through the terminal discharge track 202, and the terminal a falls into the penetration groove 203a of the terminal feeding slide 203. The blocking plate 205 plays a blocking role to prevent the terminal a from sliding out. After the material connection is completed, the first cylinder 204 drives the terminal feeding slide 203 to extend forward to the terminal pushing rod 206. Figure 7 As shown, the second cylinder 207 then drives the terminal push rod 206 to extend into the penetration groove 203a to push the terminal a into the terminal slot 101a. The state of the assembly mold 101 when the terminal assembly is completed is as shown in FIG. Fig. 9 shown.

[0045] The structure of the shrapnel assembly mechanism 3 is as follows: Fig.10As shown, it mainly includes a spring piece vibration loading tray 301, a spring piece discharging track 302 connected to the spring piece vibration loading tray 301, a spring piece feeding slide 305 is provided at the output end of the spring piece discharging track 302, and the spring piece feeding slide 305 is installed on a slide plate 304 driven by a third cylinder 303. A positioning slot 305a for positioning and receiving spring pieces b is provided on the side of the spring piece feeding slide 305 close to the spring piece discharging track 302, as shown in FIG. Fig.11 As shown, the side of the spring feeding slide 305 away from the spring discharging track 302 is also provided with a slot communicating with the positioning slot 305a (the slot is Fig.11 not shown).

[0046] A spring piece push rod 307 is also provided on one side of the spring piece feeding slide 305 where the slot is provided. The spring piece push rod 307 is driven by the fourth cylinder 306 and installed at the front end of the slide plate 304. In this embodiment, there are five spring piece push rods 307, two spring piece push rods 307 are respectively provided in the slot and on the outer side of the spring piece feeding slide 305, and one spring piece push rod 307 is provided on the top of the spring piece feeding slide 305. The spring piece push rod 307 on the top has a radially contracted extension section, and the spring piece b falls on the extension section. The five spring piece push rods 307 can cooperate to fully push the spring piece b.

[0047] A pressing mechanism is also provided above the spring sheet discharge track 302 , and the pressing mechanism includes a top block 309 that is driven to be retracted by a fifth cylinder 308 , and the top block 309 can be extended to fit against the outer end surface of the terminal a.

[0048] When the spring piece assembly mechanism 3 is working, the spring piece vibrating loading plate 301 outputs the spring piece b through the spring piece discharging track 302, and the spring piece b automatically falls onto the spring piece feeding slide 305 and is clamped into the positioning card slot 305a; then the third cylinder 303 is extended, and the spring piece feeding slide 305 sends the spring piece b to the spring piece extrusion groove 101b for extrusion and deformation, and then the fourth cylinder 306 is extended, and the five spring piece pushing rods 307 are used to push the spring piece b into the cavity of the terminal a, and the product assembly is finished as shown in FIG. Figure 1 At the same time, since there is a rebound force when the spring piece b is sent in, the fifth cylinder 308 extends and uses the top block 309 to synchronously press against the terminal a to prevent the terminal a from moving, as shown in FIG. Fig.12 shown.

[0049] The structure of the detection mechanism 4 is as follows Fig.13 As shown, it mainly includes a light source 401 arranged above the assembly table 1, and a visual inspection camera 402 arranged on one side of the light source 401. The light source 401 plays a fill light role to make the photographed product clearer. The assembled product is photographed and inspected by the inspection mechanism 4 and then discharged through the NG discharging mechanism 5 or the OK discharging mechanism 6.

[0050] The structures of the NG discharging mechanism 5 and the OK discharging mechanism 6 are as follows: Fig.14As shown, the two discharging mechanisms include a discharging pipe 7, and a push block 9 which is arranged above the feeding port of the discharging pipe 7 and is driven and retracted by the sixth cylinder 8. The push block 9 can push the push rod 101c along the guide column 102 to push the assembled product out of the assembly mold 101 and drop it into the discharging pipe 7 for output.

[0051] In addition, in this embodiment, a positioning plate 10 is also connected to the OK discharging mechanism 6. Fig.15 As shown, a detection sensor 11 is installed on the positioning plate 10 , and the detection sensor 11 is used to detect whether there is an assembly terminal a in the assembly mold 101 rotated to the terminal assembly mechanism 2 .

[0052] The automatic assembly inspection machine of the utility model can realize the automatic feeding, assembly, inspection and discharging of the terminal spring clips. Through the specially designed assembly mold and the rotation of the assembly table, the insertion and positioning of the terminal and the delivery, extrusion and deformation of the spring clips and the push-in and card-installation actions can be completed quickly and efficiently by using two independent assembly mechanisms, without manual assembly one by one. The assembled products are inspected by the inspection mechanism to see if they are qualified, and then distributed to the corresponding discharging mechanism for discharging. After the mold is emptied, the subsequent continuous assembly operation can be continued. The whole machine has a compact structure and a reasonable layout, and can automatically and efficiently realize continuous production operations, greatly improving the production rhythm and product quality, reducing production costs, and is suitable for large-scale production operations.

[0053] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
