Detailed Implementation

[0026] This application provides a cam rotation mechanism to solve the technical problems of low product conveying accuracy and long overall response time in the prior art.

[0027] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0028] By setting up a power source and a rotating device, the rotating device has a first flow channel shaft and a second flow channel shaft arranged opposite to each other. The first flow channel shaft is connected to the power source. The first and second flow channel shafts are respectively mounted on a reference seat via a first bearing seat and a second bearing seat. A planar cam is sleeved on the first bearing seat. A pin assembly is provided on the first flow channel shaft. When the power source drives the first flow channel shaft to rotate, the pin assembly can cooperate with the planar cam to connect the first and second flow channel shafts, so that the first and second flow channel shafts rotate synchronously. This achieves a simplified mechanism, improves rotational accuracy, and enables repeated cyclic rotation of products from both sides. In addition, the rotation and conveying of products can be achieved with only one power source, shortening the response time and improving production efficiency.

[0029] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] like Figures 1 to 10 The following is an embodiment of this application:

[0031] Reference Figure 1 , Figure 2 As shown, a cam rotation mechanism 100 includes a power source 2 and a rotation device 3. The rotation device 3 has a first flow channel shaft 31 and a second flow channel shaft 32 arranged opposite to each other. The first flow channel shaft 31 is connected to the power source 2. The first flow channel shaft 31 and the second flow channel shaft 32 are respectively mounted on a reference seat 35 via a first bearing seat 33 and a second bearing seat 34. A planar cam 36 is sleeved on the first bearing seat 33. A pin assembly 37 is provided on the first flow channel shaft 31. When the power source 2 drives the first flow channel shaft 31 to rotate, the pin assembly 37 can cooperate with the planar cam 36 to connect the first flow channel shaft 31 and the second flow channel shaft 32, so that the first flow channel shaft 31 and the second flow channel shaft 32 can rotate synchronously. This mechanism simplifies the structure, improves rotation accuracy, and enables repeated cyclic rotation of products from both sides. In addition, the rotation and conveying of products can be achieved with only one power source, which shortens the response time and improves production efficiency.

[0032] It is worth noting that this type of cam rotation mechanism 100 is usually a planar cam rotation mechanism.

[0033] Optional, such as Figure 8As shown, the first flow channel shaft 31 includes a first shaft portion 311 and a first base portion 312 provided at one end of the first shaft portion 311. The first base portion 312 is provided with a first flow channel 312A and two first mounting holes 312B symmetrically arranged on both sides of the first flow channel 312A. It can be understood that the two first mounting holes 312B are located on the vertical line of the first flow channel 312A.

[0034] Optional, such as Figure 9 As shown, the second flow channel shaft 32 includes a second shaft portion 321 and a second base portion 322 provided at one end of the second shaft portion 321. The second base portion 322 is provided with a second flow channel 322A and two second mounting holes 322B symmetrically arranged on both sides of the second flow channel 322A. It can be understood that the two second mounting holes 322B are located on the vertical line of the second flow channel 322A. The second mounting holes 322B and the first mounting hole 312B, as well as the second flow channel 322A and the first flow channel 312A, are respectively arranged facing each other. A product 800 can be arranged between the first flow channel 312A and the second flow channel 322A.

[0035] Optional, such as Figure 10 As shown, the pin assembly 37 has a first pin 371 and a second pin 372. The first pin 371 and the second pin 372 are respectively provided with pin portions 371A and 372A and contact caps 371B and 372B. The pin portions 371A and 372A are covered with a protective sleeve 373. A spring 374 is sleeved around the outer periphery of the protective sleeve 373. The outer diameter of the protective sleeve 373 can be matched with the inner diameter of the first mounting hole 312B to realize insertion. The outer diameter of the end of the pin portion 371A and 372A can be matched with the inner diameter of the second mounting hole 322B to realize insertion.

[0036] Optional, such as Figure 7 As shown, the planar cam 36 has a stepped portion 361, and ramp portions 362 are provided on both sides of the stepped portion 361. A reference portion 363 is provided between the two ramp portions 362. It should be noted that the stepped portion 361, the ramp portion 362, and the reference portion 363 form a circular trajectory on the plane.

[0037] Optional, such as Figure 6 As shown, the first flow channel shaft 31 also includes a product limiting part 313 disposed on the first base 312. The product limiting part 313 protrudes into the first flow channel 312A to prevent the product 800 from falling out of the first flow channel 312A.

[0038] Optional, refer again Figure 1 As shown, it also includes an origin sensing device 4 disposed between the power source 2 and the rotating device 3. The origin sensing device 4 includes a sensing plate 41 sleeved on the first rotating shaft 311 and an origin sensor 42 disposed below the sensing plate 41.

[0039] The working process of this utility model embodiment is as follows:

[0040] 1. When the flow channel conveys product 800 to the product receiving space between the first flow channel 312A and the second flow channel 322A, the cam rotation mechanism 100 is in its initial state. The first pin 371 abuts against the reference portion 363 of the planar cam 36. At this time, the spring 374 outside the first pin 371 is in a relaxed state, and the end of the pin portion 371A of the first pin 371 is not inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32. The second pin 372 is located in the middle position of the step portion 361 of the planar cam 36. At this time, the spring 374 outside the second pin 372 is fully compressed, and the end of the pin portion 372A of the second pin 372 is fully inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32 (e.g., Figure 3 (as shown)

[0041] 2. When the power source 2 drives the first flow channel shaft 31 to start rotating, the first pin 371 will move upwards to the position of the inclined section 362 on one side of the planar cam 36 as the first flow channel shaft 31 rotates. At this time, the end of the pin portion 371A of the first pin 371 is gradually inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32. The spring 374 outside the first pin 371 is gradually compressed. The second pin 372 moves downwards along the track of the stepped section 361 of the planar cam 36. At this time, the spring 374 outside the second pin 372 remains in the maximum compressed state, and the end of the pin portion 372A of the second pin 372 remains fully inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32 (e.g., Figure 4 (as shown)

[0042] 3. As the power source 2 continues to drive the first flow channel shaft 31 to rotate, the first pin 371 moves upward to the starting position of the track of the step portion 361 of the planar cam 36. At this time, the end of the pin portion 371A of the first pin 371 is fully inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32. The spring 374 outside the first pin 371 is compressed to the maximum. The second pin 372 moves downward along the track of the step portion 361 of the planar cam 36. At this time, the spring 374 outside the second pin 372 remains in the state of maximum compression, and the end of the pin portion 372A of the second pin 372 remains fully inserted into the second mounting hole 322B of the corresponding second flow channel shaft 32. At this time, the rotation of the first flow channel shaft 31 will drive the second flow channel shaft 32 to rotate synchronously, so that the product 800 can rotate synchronously (e.g., Figure 5 (as shown)

[0043] 4. As the power source 2 further drives the first flow channel shaft 31 to rotate, the first pin 371 gradually reaches the middle position of the step portion 361 of the planar cam 36, and the second pin 372 gradually reaches the position of the reference portion 363 of the planar cam 36. At this point, the positions of the first pin 371 and the second pin 372 are reversed from their initial positions, and the cam rotation mechanism 100 drives the product 800 to rotate 180 degrees. (Not shown).

[0044] It is understandable that by using the above rotation methods and rules, the product can be rotated repeatedly from front to back, that is, the product can be rotated to any angle within 360 degrees.

[0045] It is worth noting that various devices using the above-mentioned cam rotation mechanism 100 are usually component assembly devices, and naturally, they all have the advantages of the present invention and fall within the scope of protection of this concept.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
