The material block 5 can block the material passing hole 21. When the material moving block 5 moves to the material moving hole 51 and is connected with the material passing hole 21, the roller 94 enters the material moving hole 51. When the material moving block 5 equipped with the roller 94 moves to the material moving hole 51 and is connected with the material guide hole 31, the roller 94 enters the material guide hole 31, wherein the length of the material moving hole 51 is equal to the sum of the heights of the number of rollers 94 that need to be assembled at one time. A feeding block 6 is provided below the pad 3, and a feeding pipe 61 connected with the material guide hole 31 is provided on the feeding block 6. A positioning base 7 is provided on the bottom plate 11, and a driving motor 71 for driving the positioning base 7 to rotate is provided below the bottom plate 11. A slide 8 is provided on one side of the positioning base 7 on the bottom plate 11, and a slide on the slide 8 A discharge slider 81 is provided, one end of the feed pipe 61 is connected to the feed block 6, and the other end of the feed pipe 61 is connected to the discharge slider 81. A discharge hole 82 connected to the feed pipe 61 is provided on the discharge slider 81, and the discharge slider 81 can be moved to a position where the discharge hole 82 is located above the positioning base 7; a guide pipe 83 is provided at the bottom end of the discharge hole 82, and the inner diameter of the guide pipe 83 is adapted to the outer circumferential size of the roller 94; a blowing channel 22 is provided on the top plate 2, and the blowing channel 22 can be connected to the material transfer hole 51, and the blowing channel 22 is connected to a blowing pipe, and the blowing pipe is connected to an air source; the feed pipe 61 is configured as a flexible tube; the material transfer block 5 is slidably provided on the pad 3, and the pad 3 and the material transfer block 5 are connected. A dovetail groove is formed between the two, and the material transfer block 5 is connected to the material transfer cylinder 52; the length of the material transfer hole 51 is equal to the sum of the heights of the five rollers 94; a stirring motor 42 is provided above the stirring barrel 4, and the output shaft of the stirring motor 42 is connected to a rotating block 43, and the rotating block 43 is connected to a stirring shaft 44 extending into the stirring barrel 4; the feeding block 6 includes a feeding fixing block 62 and a feeding pressing block 63, and the feeding pipe 61 is fixed between the feeding fixing block 62 and the feeding pressing block 63; at least one first mounting hole 45 is provided at the bottom of the stirring barrel 4, and a second mounting hole 23 corresponding to the first mounting hole 45 is provided on the top plate 2; a switch button 14 and an electric control box 15 are provided on the frame 1.

[0030] By adopting the above technical solution, the main purpose of the tooling of the present invention is to assemble the rollers 94 into the volume grooves 93, wherein the volume grooves 93 of the rotor 92 are specifically 5, so the number of rollers 94 that need to be assembled at one time is also 5. In this way, by setting the length of the material transfer hole 51 equal to the sum of the heights of the 5 rollers 94, the number of rollers 94 that enter the material transfer hole 51 each time can be made constant at 5, so that the number of rollers 94 assembled into the volume grooves 93 is accurate. When the number of rollers 94 required for the rotor 92 is other numbers, the length of the material transfer hole 51 can also be changed by changing the installation gap 13 and the size of the material transfer block 5. Among them, the material transfer hole 51 is directly set to penetrate the upper and lower surfaces of the material transfer block 5.

[0031] When the present invention is specifically working, first of all, Figure 2 The pump cover assembly 9 shown is placed in the positioning base 7. The pump cover assembly 9 includes an eccentric sleeve 91, a rotor 92 disposed in the eccentric sleeve 91, and a volume groove 93 located on the rotor 92. After the pump cover assembly 9 is positioned by the positioning base 7, the tooling can be operated. First, the rollers 94 in the stirring barrel 4 will enter the top plate 2, wherein the stirring shaft 44 is driven to rotate by the stirring motor 42, so that the rollers 94 of the stirring barrel 4 can be more dispersed, so that the rollers 94 can be ensured to pass through the discharge hole 41 smoothly, and it is not easy to be blocked. When the roller 94 enters the feeding hole 21, since the feeding hole 21 is blocked by the material shifting block 5, the roller 94 in the feeding hole 21 will not fall, and the material shifting block 5 is moved so that the material shifting hole 51 is connected with the feeding hole 21. At this time, the roller 94 will enter the feeding hole 51. Specifically, at most 5 rollers 94 can enter at one time (this time, you take the volume slot 935 as an example). Then, the material shifting block 5 moves to the feeding hole 51 and is connected with the guide hole 31. At this time, the blowing channel 22 will also be connected with the feeding hole 51. At the same time, by driving the movement of the discharge slider 81, the discharge slider 81 is driven to move. The guide tube 83 is located above the volume groove 93. As the roller 94 enters the feed tube 61 and the guide tube 83 from the guide hole 31, and blows air into the blowing channel 22, the roller 94 can move more smoothly from the guide tube 83 to the volume groove 93 (due to the thrust generated by the blowing on the roller 94). The guide tube 83 is configured to match the roller 94, so that the position of the roller 94 in the guide tube 83 is more stable. The guide tube 83 can guide and position the roller 94, ensuring the accuracy of the position of the roller 94 falling into the volume groove 93. In addition, the rotor 92 can be rotated by the intermittent rotation of the drive motor 71, which can be a stepping motor, so that the five rollers 94 can be smoothly assembled into the volume groove 93, so that the assembly of the roller 94 can be completed.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
