[0054] like Figure 1-Figure 3 As shown, the present application discloses an automatic needle roller assembly device for realizing automatic assembly of needle rollers. To explain the needle roller, the needle roller is now described and named as a product in the following text. The product includes a handle A, a roller and a protective cover B. The roller is rotatably arranged on the handle A. The handle A can be held and the roller can be pushed to realize the rolling of the roller on the skin surface. The protective cover B can be covered on the roller to protect the roller. The roller includes a needle seat piece C, a needle piece D, a needle clamping piece E and a needle cover piece F. The needle seat piece C is a circular plate and a guide rod is provided at the center thereof. The needle piece D and the needle clamping piece E are respectively circular pieces with a through hole in the center. The circumference of the needle piece D is ringed with thorns. The needle piece D and the needle clamping piece E are spaced apart and sleeved on the guide rod of the needle seat piece C. The needle cover piece F is provided at the other end of the guide rod. The needle piece D and the needle clamping piece E are clamped on the needle seat piece C by a threaded connection or a snap-on connection.

[0055] like Figure 4 and Figure 5 As shown, a needle roller automatic assembly device includes a feeding mechanism, a loading mechanism and an equipment workbench 4, and the feeding mechanism and the loading mechanism are arranged on the equipment workbench 4, wherein the feeding mechanism includes a needle seat sheet feeding mechanism 1, a needle clamping sheet feeding mechanism 2, a needle cover sheet feeding mechanism 3 and a protective sleeve feeding mechanism 17, which are arranged in sequence on the equipment workbench 4, the needle seat sheet feeding mechanism 1 can realize the feeding of the needle seat sheet C, the needle clamping sheet feeding mechanism 2 can realize the feeding of the needle clamping sheet E, the needle cover sheet feeding mechanism 3 can realize the feeding of the needle cover sheet F, and the protective sleeve feeding mechanism 17 can realize the feeding of the protective sleeve B.

[0056] It should be noted that the needle seat sheet feeding mechanism 1, the needle clamping sheet feeding mechanism 2, the needle cover sheet feeding mechanism 3 and the protective sleeve feeding mechanism 17 have the same structure, and only the materials transported are different. The needle seat sheet feeding mechanism 1 is now taken as an example for explanation. The needle seat sheet feeding mechanism 1 includes a vibrating disk 101, a feeding slide 102 and a loading block 103. The vibrating disk 101 is arranged on the equipment workbench 4. The vibrating disk 101 realizes the feeding of the needle seat sheet C by vibration. One end of the feeding slide 102 is arranged at the discharge port of the vibrating disk 101. The needle seat sheets C in the vibrating disk 101 are introduced into the feeding slide 102 one by one (the width of the feeding slide 102 only allows one material to pass through, and the other feeding mechanisms are the same and will not be repeated). A loading block 103 is provided at the other end of the feeding slide 102. The loading block 103 is arranged at the other end of the feeding slide 102, which is driven by a driving mechanism. It can move laterally to the discharge port of the feeding slide 102, wherein the loading block 103 is a rectangular parallelepiped, and a feeding trough is provided on the side close to the feeding slide 102 (the feeding trough can only accommodate one material, and the other feeding mechanisms are the same, which will not be repeated). When the loading block 103 moves laterally to the limit in one direction, the feeding trough docks with the feeding slide 102. Due to the vibration of the vibrating disk 101, the needle seat piece C in the feeding slide 102 has a tendency to move toward the loading block 103, and the needle seat piece C placed in the front is pushed into the feeding trough. After the loading block 103 moves laterally to the other side, the discharge port of the feeding channel 102 and the feeding trough are staggered, and the side wall of the loading block 103 is against the discharge port of the feeding channel 102, and the discharge port of the feeding slide 102 is blocked by the side wall of the loading block 103. At this point, the loading of the needle seat piece C is completed.

[0057] The feeding trough can only accommodate one material at a time, and by moving the loading block 103 so that it is staggered with the discharge port of the feeding channel 102, it can keep the material in the feeding trough from being closely attached to one side by another, and ensure that the material is not interfered with by other materials when being grabbed and transplanted.

[0058] like Figure 1 、 Figure 6 and Figure 8 As shown, the feeding mechanism includes a needle seat sheet feeding mechanism 5, a needle clamping sheet and needle sheet assembly mechanism 7, a needle cover sheet assembly mechanism 9 and a protective sleeve assembly mechanism 13, which are arranged in sequence on the equipment workbench 4 and arranged side by side with the feeding mechanism, wherein the needle seat sheet feeding mechanism 5 is arranged above the needle seat sheet feeding mechanism 1 through a support frame. In order to realize the flow of the needle seat sheet feeding mechanism 5 between the feeding trough and the conveyor line, a transverse module is provided on the support frame. The needle seat sheet feeding mechanism 5 is arranged at the driving end of the transverse module, and the movement of the needle seat sheet feeding mechanism 5 is driven by the transverse module.

[0059] Specifically, the needle seat piece feeding mechanism 5 includes a needle seat piece driving mechanism 501 and a needle seat piece clamping mechanism 502. The needle seat piece clamping mechanism 502 is arranged at the driving end of the needle seat piece driving mechanism 501. The needle seat piece driving mechanism 501 can drive the needle seat piece clamping mechanism 502 to descend to the feeding trough at the loading block 103, and clamp the needle seat piece C. After completing the material collection of the needle seat piece C, the needle seat piece driving mechanism 501 drives the needle seat piece clamping mechanism 502 to lift up. At this time, the transverse movement module drives the needle seat piece feeding mechanism 5 to move to the conveyor line.

[0060] Among them, the needle clamping piece and needle piece assembly mechanism 7, and the needle cover piece assembly mechanism 9 have the same structure and function as the needle seat piece feeding mechanism 5, respectively, and their clamping methods of the materials are different. The difference is that the needle seat piece clamping mechanism 502 uses a clamping cylinder to clamp the needle seat piece C, and the clamping part of the clamping cylinder can clamp the guide rod of the needle seat piece C, while the other two groups of feeding mechanisms clamp and fix the material by adsorption. The two groups have the same structure. The needle clamping piece and needle piece assembly mechanism 7 are used as an example for explanation. It includes a clamping assembly driving mechanism 701 and a clamping assembly adsorption head 702. The clamping assembly adsorption head 702 absorbs the needle clamping piece E through a negative pressure suction head, and the needle cover piece assembly mechanism 9 absorbs the needle cover piece F in the same way.

[0061] like Figure 1 As shown, the feeding mechanism also includes a needle sheet feeding mechanism 6, which is arranged on one side of the conveying path 8 and is opposite to the needle clamping sheet feeding mechanism 2. The feeding troughs of the needle sheet feeding mechanism 6 and the needle clamping sheet feeding mechanism 2 are on the travel trajectory of the needle clamping sheet and the needle sheet assembly mechanism 7. A needle sheet D is sleeved on the needle sheet feeding mechanism 6, and the needle clamping sheet and the needle sheet assembly mechanism 7 take materials in turn between the needle clamping sheet feeding mechanism 2 and the needle sheet feeding mechanism 6.

[0062] like Figure 7 As shown, preferably, the needle feeding mechanism 6 includes a mounting frame 61, a longitudinal moving module 62, a push rod 63 and a movable top plate 64. The mounting frame 61 is arranged on the equipment workbench 4, and a through opening is provided on one side of the equipment workbench 4. The longitudinal moving module 62 is arranged on the mounting frame 61, and part of it can pass through the through opening and be located below the table top of the equipment workbench to improve space utilization. The movable top plate 64 is an L-shaped plate, which is arranged at the driving end of the longitudinal moving module 62. Its vertical portion can move in and out relative to the through opening, and its horizontal portion is provided with a through hole, which can pass through the push rod 63. The needle piece D mounted on the push rod 63 is supported by the horizontal portion of the movable top plate 64. As the needle pieces D mounted on the top rod 63 are continuously removed, the longitudinal movement module 62 can drive the movable top plate 64 to continuously move in the vertical direction. During the upward movement of the movable top plate 64, all the needle pieces D are driven upward, so that the topmost needle piece D can always be at the same height when the material is being taken, which can facilitate the material taking work.

[0063] It should be noted that a conveying path 8 is provided between the feeding mechanism and the loading mechanism. The loading mechanism takes the material from the feeding mechanism and is assembled on the conveying path 8. The needle seat piece loading mechanism 5 first grabs the needle seat piece C from the needle seat piece feeding mechanism 1 and places it on the conveying path 8. Then the needle clamping piece and the needle piece assembly mechanism 7 respectively absorb the needle clamping piece E and the needle piece D from the needle clamping piece feeding mechanism 2 and the needle piece feeding mechanism 6 and sleeve them on the needle seat piece C. It should be noted that in this embodiment, the needle piece and the needle piece clamping piece are respectively Multiple groups of needle blades are provided and alternately stacked on the needle base plate. The bottom and top are both needle blades. The needle blade clamping plate is located between two adjacent needle blades. Assuming the number of needle blades is N, the number of needle blade clamping plates is N-1. In this embodiment, there are 9 groups of needle blades and 8 groups of needle blade clamping plates. Finally, the needle cover plate assembly mechanism 9 draws the needle cover plate F from the needle cover plate feeding mechanism 3 and covers it on the needle base plate C. At this point, the assembly of the semi-finished roller is completed. During the assembly process, the conveying path 8 will move with the assembly action. In this embodiment, the conveying path 8 includes a conveyor line and a carrier plate. The carrier plate reciprocates between the front and rear ends relative to the conveyor line. The assembly of the semi-finished roller mentioned above is completed on the carrier plate.

[0064] See Figure 4 As shown, the automatic needle roller assembly equipment also includes a roller transfer mechanism 10 and a roller material picking seat 11. The transfer mechanism 10 and the roller material picking seat 11 are both arranged on the equipment workbench 4. The transfer mechanism 10 can absorb the assembled semi-finished roller from the conveying path and place it on the roller material picking seat 11. The two cooperate to transfer the semi-finished roller. The semi-finished roller after being transferred can be suspended below, which is convenient for grabbing it in the subsequent process.

[0065] Specifically, if Figure 7 As shown, the roller picking seat 11 is provided with a pin drive mechanism 1101 and a pin 1102. The pin 1102 is composed of two cylindrical rods of different diameters, which are coaxially connected. For the convenience of description, the cylindrical rod with a larger diameter is called the large cylindrical rod, and the other is called the small cylindrical rod. The large cylindrical rod is connected to the pin drive mechanism 1101, and the diameter difference between the two forms a step structure. The semi-finished roller can be mounted on the small cylindrical rod and supported by the upper end face of the large cylindrical rod. It should be emphasized that the diameter of the large cylindrical rod is smaller than the diameter of the semi-finished roller to ensure that the outer ring of the lower surface of the semi-finished roller has no support, so as to reserve a clamping position to facilitate the normal operation of subsequent processes. The pin drive mechanism 1101 can lift the pin 1102 and the semi-finished roller to a certain height.

[0066] like Figure 4 and Figure 10As shown, the automatic needle roller assembly equipment also includes a roller picking mechanism 14, which is supported and mounted on the equipment workbench 4. It can be moved laterally along the support frame through a transverse movement mechanism. The protective cover and roller picking mechanism 14 includes a roller into the handle assembly mechanism 12 and a protective cover assembly mechanism 13. The roller into the handle assembly mechanism 12 is used to grab the semi-finished roller assembled in the previous process and realize the assembly of the roller on the handle A. The protective cover assembly mechanism is used to assemble the protective cover to the handle A.

[0067] Preferably, the roller feeding handle assembly mechanism 12 includes a roller material picking drive mechanism 1201, a roller material picking rotation mechanism 1202 and a roller material picking clamping mechanism 1203. The roller material picking drive mechanism 1201 can drive the roller material picking rotation mechanism 1202 to move in the vertical direction, the roller material picking rotation mechanism 1202 can drive the roller material picking clamping mechanism 1203 to rotate, and the roller material picking clamping mechanism 1203 clamps the roller by driving the plywood on both sides. It should be noted that arc grooves are provided on the driving plywood on both sides of the roller material picking clamping mechanism 1203. Because the roller is now mounted on the roller material picking seat 11, and the needle piece D is provided with thorns, it cannot be clamped from both sides and needs to be clamped from the upper and lower ends of the roller. For clamping, the roller picking mechanism 14 needs to move the clamping end of the roller picking clamping mechanism 1203 toward the roller and be in the upper and lower clamping positions, and after descending to the height of the roller, move the clamping end of the roller picking clamping mechanism 1203 to the roller, so that the roller is in the clamping end of the roller picking clamping mechanism 1203. At this time, the arc-shaped groove opened on the driving splint can avoid the ejector 1102, and the roller picking clamping mechanism 1203 clamps the roller and moves it up and takes it out; on the other hand, it is to avoid the two side plates at the installation position of the handle A. The two side plates can respectively extend into the arc-shaped groove, driving the semi-finished roller to extend into the installation position formed by the two side plates of the handle A, providing a avoidance position for the installation of the semi-finished roller relative to the handle A.

[0068] As a preferred embodiment, a handle carrier transfer mechanism 15 and a handle loading carrier 16 are also provided on the equipment workbench 4. The handle loading carrier 16 is slidably connected to the equipment workbench 4 through the handle carrier transfer mechanism 15 to realize the conversion of the loading position and the working position. The handle A is placed on the handle loading carrier 16 manually. Because the two clamping ends of the handle A for clamping the roller can be embedded in the arc grooves on the driving splints on both sides of the roller material clamping mechanism 1203, the roller material clamping mechanism 1203 can clamp the The roller is pressed vertically downward on the handle A. At this point, the work of the roller entering the handle A is completed. Finally, the protective cover assembly mechanism 13 clamps the protective cover B from the protective cover feeding mechanism 17 and buckles it on the handle A. The protective cover assembly mechanism 13 includes a protective cover material taking drive mechanism 1301 and a protective cover material taking clamping mechanism 1302. The functions are the same as those of the needle seat sheet loading mechanism 5 and will not be repeated here. Finally, the handle carrier transfer mechanism 15 is manually exited and the assembled product is taken out and placed in the handle A, and the cycle is repeated.

[0069] The above is only a preferred embodiment of the carrier disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
