[0002] The common circular track structure on the market currently has no ferry return mechanism for the carriers at both ends and no automatic braking structure after the carriers are in place. As a result, when the carriers alternate between the two ends, they need to wait for the moving stroke time and the ferry reciprocating time. The overall stay time is too long, affecting the overall beat of the equipment. In addition, after the flow-following carrier components are in place, the position of the flow-following carrier components is easily changed. For the flat circular track, due to the single-track support, the overall rigidity and precision are poor, and it cannot carry large-size products for inspection. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Figures 1 to 6 A high-speed fork-type circular track device with carrier reflow shown in the figure comprises two carrier fork transfer mechanisms 21 installed in parallel and at intervals, and carrier ferry return mechanisms 22 respectively installed at the ends of the two carrier fork transfer mechanisms 21. The two carrier fork transfer mechanisms 21 and the two carrier ferry return mechanisms 22 are connected to form a return track, and the return track drives the product 6 to move in a single direction on the return track;

[0032] The carrier fork flow mechanism 21 includes a main slide rail 211, on which a plurality of flow-following carrier components 23 for placing products 6 are slidably installed. The flow-following carrier components 23 include a base plate 231, and the bottom of the base plate 231 has a slider that slidably cooperates with the main slide rail 211. Two elastic members 232 are relatively installed on the base plate 231. The inner support member 233 supports the product internally through a connecting member 26 that is narrow in front and wide in the back and the carrier opening and closing mechanism 25. The inner support member 233 is a T-shaped structure, and an upper base plate 234 with an opening in the middle is installed above the elastic member 232. The T-shaped structure is movably installed in the opening of the upper base plate 234. The vertical section of the T-shaped structure passes through the opening and is connected to the elastic member 232. The horizontal section of the T-shaped structure is located on the upper side of the upper base plate 234. Internal support or clamping can be achieved by installing components at different ends of the elastic member 232. Clamping can be achieved by installing the components on the inner side of the elastic member 232, and internal support can be achieved by installing the components on the outer side of the elastic member 232. Internal support is preferred in this application.

[0033] A shift block 235 is installed on the base plate 231, and the shift block 235 protrudes outward from the main slide rail 211. The shift fork assembly 24 includes a moving rail 241, and a driving body 242 is installed on the moving rail 241. The driving body 242 drives itself to move back and forth on the moving rail 241, and drives the shift fork 243 to extend or retract at the same time. The shift fork 243 extends and snaps on the shift block 235, thereby driving the flow-following carrier assembly 23 to move in steps. The shift fork 243 retracts to release the shift block 235, and the driving body 242 retreats. The shift block 235 cooperates with the shift fork assembly 24 to drive the flow-following carrier assembly 23 to move in steps on the main slide rail 211 or the auxiliary slide rail 2241.

[0034] A brake assembly is also installed at the lower part of the base plate 231. When the shift block 235 cooperates with the shift fork assembly 24, the brake assembly is separated from the main slide rail 211 or the auxiliary slide rail 2241. When the shift block 235 is separated from the shift fork assembly 24, the brake assembly is in contact with the main slide rail 211 or the auxiliary slide rail 2241 for braking.

The brake assembly includes a Z-shaped mounting member, which is rotatably mounted at the bottom of the base plate 231. A seat block 237 is installed on the Z-shaped extension end of the mounting member. A spring 238 is installed at the rear end of the seat block 237. A positioning block is installed at the rear end of the spring 238. The positioning block is fixedly installed at the bottom of the base plate 231. A brake pad 239 is installed at the front end of the seat block 237. The front end of the brake pad 239 is close to the inner side of the main slide rail 211 or the auxiliary slide rail 2241. The mounting member A top block 236 is installed at the end of the Z-shaped extension section. The top block 236 passes through the gap between the main slide rail 211 or the auxiliary slide rail 2241 and the bottom of the base plate 231, and faces the direction of the fork assembly 24. After the fork assembly 24 is ejected, the top block 236 presses and rotates the mounting piece, so that the brake pad 239 moves away from the main slide rail 211 or the auxiliary slide rail 2241. Conversely, the fork assembly 24 retracts, and the mounting piece rotates under the action of the spring 238, so that the brake pad 239 is close to the main slide rail 211 or the auxiliary slide rail 2241 to achieve braking.

[0036] At least one carrier opening and closing mechanism 25 is disposed on the inner side of the main slide rail 211. The carrier opening and closing mechanism 25 is horizontally oriented toward the flow-following carrier assembly 23. The carrier opening and closing mechanism 25 is horizontally pushed out through two connecting members 26 that are narrow in front and wide in the back, or presses the elastic member 232 inwardly so that the inner support member 233 closes inwardly to release the product 6, or presses the elastic member 232 outwardly so that the clamping member 41 expands outwardly to release the product 6.

[0037] Secondary positioning mechanisms 27 are installed on both sides of the main slide rail 211. The product 6 passes through the middle area of ​​the secondary positioning mechanism 27, and the secondary positioning mechanism 27 is closed inward to realize secondary positioning of the product;

[0038] The carrier ferry return flow mechanism 22 includes an upper ferry return flow plate 221 and a lower ferry return flow plate 222, which are installed at intervals in the upper and lower directions. Return slide rails 223 are installed on the upper ferry return flow plate 221 and the lower ferry return flow plate 222, and the return slide rails 223 are perpendicular to the main slide rails 211 in the carrier shift fork flow transfer mechanism 21. Both sides of the lower ferry return flow plate 222 are installed with a vertically lifted flow-following carrier assembly 23 flush with the upper ferry return flow plate 221, or a return assembly 224 vertically lowered to be flush with the lower ferry return flow plate 222;

[0039] The return assembly 224 includes an auxiliary slide rail 2241 matched with the main slide rail 211, and a translation slide rail 2242 matched with the return slide rail 223. A return substrate 2243 is slidably installed above the translation slide rail 2242, and the auxiliary slide rail 2241 is installed above the return substrate 2243. The translation slide rail 2242 and the auxiliary slide rail 2241 are installed in a cross shape on the upper and lower sides of the return substrate 2243.

[0040] The inner sides of the upper ferry return plate 221 and the lower ferry return plate 222 are close to the main slide rail 211, and the outer sides of the upper ferry return plate 221 and the lower ferry return plate 222 are provided with a moving component 28 that drives the flow-following carrier component 23 on the upper ferry return plate 221 and the lower ferry return plate 222 to translate from one side of the carrier fork flow transfer mechanism 21 to the other side of the carrier fork flow transfer mechanism 21;

[0041] The moving assembly 28 includes a cylinder 281 installed up and down. When the return assembly 224 lifts or lowers the flow-following carrier assembly 23 to a position, the cylinder 281 extends out. The end of the flow-following carrier assembly 23 has a matching portion. After the extended end of the cylinder 281 extends into the matching portion, the translation of the flow-following carrier assembly 23 is achieved by a motor drive or a screw drive.

[0042] An AOI visual inspection mechanism is installed on the return track formed by connecting two carrier shift fork transfer mechanisms 21 and two carrier ferry return mechanisms 22.

[0043] When the material is incoming, the return assembly 224 lifts the return base plate 2243 through the cylinder, so that the auxiliary slide rail 2241 is flush with the main slide rail 211, and the translation slide rail 2242 is flush with the return slide rail 223 on the upper ferry return plate 221. The carrier fork flow transfer mechanism 7 drives the flow-following carrier assembly 23 to translate onto the auxiliary slide rail 2241, and the cylinder 281 of the moving assembly 28 extends out to connect the end of the flow-following carrier assembly 23 or the end of the return base plate 2243, driving the return base plate 2243 and the flow-following carrier assembly 23 to translate to the opposite side through the return slide rail 223. At this time, the product 6 is placed on the flow-following carrier assembly 23, and the carrier opening and closing mechanism 25 cooperates with the robot to take away the product 6, and the empty flow-following carrier assembly 23 descends and returns to its original position from the return slide rail 223 on the lower ferry return plate 222.

[0044] Both ends of the return track are equipped with a carrier ferry return mechanism 22. The movement logic of the carrier ferry return mechanism 22 is consistent with the above example. There are slight differences in actual use, such as single-side return use or return use.

[0045] When using reflux, refer to Figure 1 The upper left is the loading position. The product 6 to be inspected is placed on the empty flow carrier assembly 23. The product 6 to be inspected is first moved forward by the carrier fork flow mechanism 21, and then translated to the carrier fork flow mechanism 21 on the lower side. The visual inspection is completed when the product 6 moves, and finally to the Figure 1 The lower left unloading position unloads the material, takes out the product 6, and then the empty flow carrier assembly 23 returns to the loading position;

[0046] When using single-side reflux, refer to Figure 1The upper left is the loading position, and the product 6 to be tested is placed on the empty flow-following carrier assembly 23. The product 6 to be tested is first driven by the carrier fork flow mechanism 21 to move forward to the rear carrier ferry return mechanism 22. Figure 1 In the upper right position, the visual inspection is completed when the product 6 moves. After the product 6 is taken away, the empty flow carrier assembly 23 descends and moves horizontally to the lower side, and then rises to Figure 1 Load the material in the lower right middle, and then move back to Figure 1 At the lower left position, the visual inspection is completed when the product 6 moves. After the product 6 is taken away, the empty flow carrier assembly 23 is lowered and then moved to the upper side, and then raised to Figure 1 Repeat this process of adding material to the upper left center.
