DETAILED DESCRIPTION

[0027] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0028] Embodiment one

[0029] As shown in a feeding mechanism shown in Figure 1 and Figure 3 , which is used for moving and transferring joints on a medical accessory connector. The joint is in the form of a ring column structure and has a hole at both ends. The feeding mechanism comprises a feeding assembly, a conveying line 1 and a feeding assembly. The feeding assembly is preferably a sieve disc combined with a mechanical arm to code and feed the conveying line 1. The conveying line 1 comprises a back-shaped reciprocating circulating conveying belt, and carriers 11 are fixedly arranged on the conveying belt at intervals. The carriers 11 are provided with clamping grooves for carrying materials, and the clamping grooves are open on one side in the width direction of the conveying line 1. The feeding assembly is arranged on the side edge of the conveying line 1 on the open side of the clamping groove, and the feeding assembly comprises a lateral movement drive, a vertical lifting drive and a material taking piece 3. The lateral movement drive is a sliding table cylinder one 7, which is fixed on a base 25. The vertical lifting mechanism is fixed on the sliding table of the sliding table cylinder one 7 and is driven to move laterally. The vertical lifting mechanism comprises a sliding table cylinder two 8 and a lifting platform 2. The lifting platform 2 is fixed on the sliding table of the sliding table cylinder two 8 and is driven to move up and down. This design drives stable movement and is accurate. The material taking piece 3 is installed on the lifting platform 2 and is driven by the sliding table cylinder one 7 to move towards the conveying line 1 and contact the material in the clamping groove of the carrier 11. The material taking piece 3 is lifted by the sliding table cylinder two 8 to make the material separate from the carrier 11 and be lifted to a certain height to wait to be taken away by a processing station. Two material taking pieces 3 are arranged at intervals on the lifting platform 2 of the present application. Two materials can be taken away from the conveying line 1 at a time by the two material taking pieces 3. The two material joints correspond to the processing requirements at the processing station. The two material taking pieces 3 are slidingly connected to the lifting platform 2, and the two material taking pieces 3 can adjust the distance between the two materials to a suitable position for processing requirements of the processing station after taking the materials down. The clamps of the processing station can directly take the materials from the material taking piece 3 for processing, which meets the direct matching of the materials between the conveying line 1 and the processing station, greatly improving the adaptability of the conveying line 1.

[0030] As shown in a feeding mechanism shown in Figure 2 and Figure 3The lifting platform 2 shown is arranged with three blocks 22 at intervals in the conveying direction of the conveying line 1, and the sliding spaces 24 are formed at two adjacent blocks 22, and the middle block 22 can be regarded as a reference, and the linear guide rail 4 is fixed at the lifting platform 2 close to the block 22, and the arrangement direction of the linear guide rail 4 is the same as the arrangement direction of the three blocks 22, and two sliding blocks 31 are slidably connected to the linear guide rail 4, and the sides of the two sliding blocks 31 respectively correspond to extend into one sliding space 24, so that the sliding blocks 31 are limited by the blocks 22 when moving left and right, so that each sliding block 31 has two limit positions left and right, and two material taking members 3 are correspondingly fixed on one sliding block 31, so that the two sliding blocks 31 approach each other to reach the limit position when the material taking limit position of the material taking device 11 is reached, and the two sliding blocks 31 are away from each other to reach the material feeding limit position, that is, the variable pitch position, so that the material taking member 3 is very stable and accurate in taking and feeding the material, and can meet the rapid matching of the material on the conveying line 1 and the processing station, and further improve the adaptability of the conveying line 1. Further, the bolts 23 are threadedly connected to the opposite sides of the adjacent blocks 22, and the length of the bolts 23 can be adjusted by thread rotation, so that the above-mentioned material taking limit position and material feeding limit position can be adjusted and corrected very conveniently, and the adaptability of the conveying line 1 is further improved.

[0031] As Figure 3 The movement of the two material taking members 3 is driven by the linkage of the connecting rods 5 and the driving member 52, and the specific process is as follows: equal-length connecting rods 5 are hinged to the sides of the two sliding blocks 31, and the other ends of the two connecting rods 5 are hinged to each other to form a push-pull part 51, and the driving member 52 is a push rod cylinder, which is vertically upward and directly connected with the push-pull part 51, and the extension of the push rod of the push rod cylinder can drive the connecting rods 5 to drive the two sliding blocks 31 to move away from each other, and vice versa. The design ensures that the position of the push rod cylinder and the length of the connecting rods 5 remain unchanged, and the adjacent material taking members 3 can move symmetrically very accurately, and the center of symmetry is the push-pull part 51, which can also be defined as a reference. The accurate and rapid taking and feeding can improve the efficiency of the production line and further improve the adaptability of the conveying line 1. Further, the bottom of the lifting platform 2 is fixed with a bottom plate 21, and a long strip-shaped stroke groove 211 is formed in the bottom plate 21, and the stroke groove 211 is vertically arranged at a position corresponding to the push-pull part 51, and the push-pull part 51 protrudes a guide part 53 which is clamped in the stroke groove 211. The guide part 53 can move in the stroke groove 211, so that the push-pull part 51 moves back and forth in the vertical direction very stably and accurately, so that the material taking member 3 can quickly and accurately change the pitch to meet the needs of the processing station.

[0032] As a preferred option, the material taking part 3 of the present application is a plug rod, one end of the plug rod is fixed on the sliding block 31, the other end of the plug rod is towards the opening direction of the carrier 11, because the material has a hole position on the opening side, the size of the end of the plug rod is matched with the inner diameter of the hole position, the end of the plug rod can be matched with the material, after the matching, the material is lifted up from the carrier 11 by lifting the lifting platform 2, and after lifting, the material is at a certain height for the machining station to clamp and take away for machining, the structure is designed cleverly, the material taken by the conveying line 1 can be directly matched with machining, and the adaptability is further improved.

[0033] As a preferred option, a baffle 12 is installed on the rack of the conveying line 1 near the opening side of the carrier 11, the baffle 12 can block the opening side, effectively preventing the material from being misaligned or falling during the transfer process and affecting the subsequent material taking. And two material taking openings 121 corresponding to the plug rod are formed on the baffle 12 at the position of the feeding assembly, the plug rod can be inserted into the material from the material taking opening, the conveying line 1 designed in this way has better stability when moving the material. At the same time, a movable cover 6 is designed on the other side or above the conveying line 1, the cover 6 can be shielded above the corresponding carrier 11 when the plug rod inserts the material, which can effectively prevent the material from being displaced upward under force, and improve the success rate of the plug rod inserting the material. When the material needs to be lifted, the cover 6 moves away from above the carrier 11 to avoid interference. The specific driving mode of the cover 6 adopts a pneumatic cylinder, a support is designed on the other side of the conveying line 1, a pneumatic cylinder is installed on the support, and the cover 6 is moved towards the conveying line 1 by the pneumatic cylinder. This design greatly improves the stability and success rate of material taking.

[0034] As shown in Figure 1 , Figure 2 and Figure 3 , the operation process of the joint assembly station applied to the present feeding mechanism is as follows: first, the mechanical arm clamps the joint from the material tray to the carrier 11 on the conveying line 1; second, the conveying line 1 transfers the material with the joint to the area where the feeding assembly is located, the materials on the two carriers 11 are opposite to the two material taking openings 121; third, the cover 6 is shielded above the conveying line 1 at the material taking opening 121, and the plug rod is inserted into the material taking opening 121 under the drive of the sliding table pneumatic cylinder 7, then the cover 6 retreats, and the sliding table pneumatic cylinder 8 drives the plug rod to lift to the feeding height; fourth, the rotary assembly arm moves to hold the end of the joint and moves to the waiting assembly position; fifth, the two rotary assembly arms advance to insert the joint into the two ends of the pipe and tighten, the improved conveying line 1 directly matches the machining requirements of the material output, greatly reducing the time of rearrangement, and greatly improving the production efficiency of the production line while improving the adaptability of the conveying line 1.
