Detailed implementation manners

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] The left, right, up, and down positions of each component shown in the drawings are just an arrangement method, and the specific positions are set according to specific needs.

[0032] In one embodiment, as Figures 1-4 shown, a connector plastic part anti-drop conveying device includes a belt conveying component 100, a material receiving rod frame 200, and a blanking frame body 300. The material receiving rod frame 200 and the blanking frame body 300 are respectively arranged at both ends of the belt conveying component 100. The belt conveying component 100 includes two belt wheel parts 110 and a conveyor belt 130 wound between the two belt wheel parts 110. The two belt wheel parts 110 are respectively rotatably arranged on the material receiving rod frame 200 and the blanking frame body 300, and a conveying motor 120 is connected to the end of one of the belt wheel parts 110. The outer surface of the conveyor belt 130 has a plurality of evenly spaced pusher units 140; the top of the material receiving rod frame 200 has two guide rods 210, and a material receiving frame assembly 400 located above the belt conveying component 100 is arranged between the two guide rods 210. The material receiving frame assembly 400 includes a material receiving frame body 410 and two side sliders 440. The side wall of the material receiving frame body 410 away from the belt conveying component 100 is an arc structure and extends to the bottom of the material receiving frame body 410. A plurality of pusher notches 430 are formed on the bottom wall of the material receiving frame body 410, and a material receiving elastic cushion layer 420 is covered on the inner bottom wall of the material receiving frame body 410. The two side sliders 440 are respectively fixedly arranged on the two side walls of the material receiving frame body 410, and the side sliders 440 are slidably matched with the guide rods 210 on the same side. A buffer spring part 450 is connected between the side sliders 440 and the top of the material receiving rod frame 200; two groups of side connecting plates 500 are also arranged between the material receiving rod frame 200 and the blanking frame body 300 and are respectively distributed along both sides of the belt conveying component 100, and a plurality of anti-drop protection plate assemblies 600 are arranged on each side connecting plate 500.

[0033] In the embodiment of the present invention, the connector plastic parts processed on the processing equipment fall from the upper side of the receiving frame 410 to the inside of the receiving frame 410. Since the receiving spring cushion layer 420 has a certain flexibility, the connector plastic parts can be prevented from directly colliding with the receiving frame 410 and being damaged. After the receiving frame 410 is impacted by the falling connector plastic parts, the receiving frame 410 moves downward under the guidance of the guide rod 210 and compresses the buffer spring part 450, so that the buffer spring part 450 can play a buffering role. The downward movement of the receiving frame 410 and the elasticity of the buffer spring part 450 can effectively buffer the impact caused by the falling of the connector plastic parts and reduce the rebound of the connector plastic parts. The side wall of the receiving frame 410 prevents the connector plastic parts from bouncing up and popping out of the conveying belt 100 after falling. The connector plastic parts slide down onto the conveyor belt 130 under the guidance of the arc-shaped structure side wall of the receiving frame 410. The conveying motor 1 20 works and drives the pulley part 110 to rotate, and the pulley part 110 drives the conveyor belt 130 thereon to move in a circular motion, so that the conveyor belt 130 drives the connector plastic parts thereon to move toward the blanking frame 300 to complete the conveying, and the multiple pushing units 140 on the conveyor belt 130 can prevent the connector plastic parts from sliding on the conveyor belt 130 and affecting the conveying; the connector plastic parts will be retained at the bottom of the receiving frame 410, so that the receiving frame 410 bears the weight of the connector plastic parts and gradually approaches the conveyor belt 130; when the pushing unit 140 passes the bottom of the receiving frame 410, the top of the pushing unit 140 can extend to the inside of the receiving frame 410 through the pushing notch 430, so that the top of the pushing unit 140 can take away the connector plastic parts in the receiving frame 410 and move them to the upper surface of the conveyor belt 130; thereby, the connector plastic parts can be transported in an orderly manner and prevented from popping out of the conveyor belt 130 due to falling rebound.

[0034] In one embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the pushing unit 140 includes a strip member 141 and a plurality of pushing protrusions 142, the strip member 141 is transversely mounted on the surface of the conveyor belt 130 and is detachable, the plurality of pushing protrusions 142 are fixed on the upper surface of the strip member 141 at equal intervals and the plurality of pushing protrusions 142 respectively correspond to a plurality of pushing notches 430; in the embodiment of the present invention, the detachable connection between the strip member 141 and the conveyor belt 130 can be connected by a fastening mechanism such as screws, and the pushing unit 140 can be replaced in time according to the wear of the pushing protrusions 142; when the bottom of the material receiving frame assembly 400 is close to the upper surface of the conveyor belt 130 and the pushing unit 140 is at the bottom of the material receiving frame assembly 400, the pushing protrusion 142 can pass through the corresponding pushing notch 430 and move the connector plastic part on the inner side of the material receiving frame body 410, so that the connector plastic part falls completely on the conveyor belt 130.

[0035] In one embodiment,Figure 1 , Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the pushing protrusion 142 is made of rubber material, and the upper surface of the strip plate member 141 has a magnetic sheet, and the outer wall of the bottom of the material receiving frame 410 has a magnetic block. In the embodiment of the present invention, when the pushing protrusion 142 made of rubber material toggles the connector plastic part, it will not scratch the surface of the connector plastic part. Secondly, when the material receiving frame 410 is relatively light and the pushing protrusion 142 cannot pass through the pushing notch 430, the magnetic sheet on the strip plate member 141 and the magnetic block at the bottom of the material receiving frame 410 generate a mutually acting magnetic attraction force, so that the material receiving frame 410 can move downward, ensuring that the pushing protrusion 142 can pass through the pushing notch 430 and extend into the interior of the material receiving frame 410.

[0036] In one embodiment, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , two pushing racks 465 are provided at the top of the material receiving rod frame 200 and are respectively located outside the material receiving frame 410. A rotating pushing part 460 is further provided inside the material receiving frame 410, and the rotating pushing part 460 includes two rotating cylinders 461 and two support arm rods 462. The two rotating cylinders 461 are rotatably arranged on the side wall of the material receiving frame 410 in a symmetric distribution manner. The center line of the rotating cylinder 461 coincides with the bottom center line of the arc-shaped structure of the material receiving frame 410. One end of the rotating cylinder 461 extends to the outside of the material receiving frame 410 and is provided with a pushing gear 464 corresponding to and meshing with the pushing rack 465. One end of the support arm rod 462 is fixedly connected to the end of the rotating cylinder 461 extending into the material receiving frame 410. Pushing rollers 463 are provided at the ends of the two support arm rods 462 away from the rotating cylinder 461. In the embodiment of the present invention, when the material receiving frame 410 moves vertically relative to the guide rod member 210, due to the meshing of 454 with the pushing rack 465, the rotating cylinder 461 rotates and the rotating cylinder 461 drives 452 to rotate, so that the pushing roller 463 rotates along the bottom of the material receiving frame 410, and the pushing roller 463 can push the connector plastic part in the material receiving frame 410 onto the upper surface of the conveyor belt 130. The pushing roller 463 is made of rubber material and will not scratch the connector plastic part.

[0037] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 6As shown, a support rod member 510 is provided on the outer wall of the side connection plate 500, and the anti-falling guard plate assembly 600 includes a side guard plate 610 and a mounting portion 630. The surface of the side guard plate 610 facing the belt conveying member 100 has a plurality of mounting portions 630. The mounting portions 630 are connected to the outer surface of the side guard plate 610, and the mounting portions 630 and the support rod member 510 are rotationally connected through a spring bearing in a damped manner. In an embodiment of the present invention, in the initial state, due to the elastic action of the spring bearing, the side guard plate 610 can be in a vertical state, which can, to a certain extent, prevent the connector plastic parts on the conveyor belt 130 from detaching from the side. Among them, the spring bearing is a structure in which a spring is provided between the inner ring and the outer ring of the bearing. When it is necessary to take the connector plastic parts from the side of the conveyor belt 130, the corresponding mounting portion 630 is pulled to rotate it around the support rod member 510, so that the side guard plate 610 can rotate from the vertical state to the horizontal state, facilitating the taking of the connector plastic parts. When the side guard plate 610 is in the horizontal state, the upper surface of the side guard plate 610 is flush with the upper surface of the conveyor belt 130.

[0038] In one embodiment, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, the mounting portion 630 includes a barrel seat portion 631, an upper connecting portion 632, and a lower acting plate 633. The barrel seat portion 631 is rotationally sleeved on the support rod member 510 through a spring bearing. One end of the upper connecting portion 632 is connected to the barrel seat portion 631, and the other end is fixedly connected to the side guard plate 610. The lower acting plate 633 is fixedly connected to the barrel seat portion 631, and a handle 635 is provided on the lower acting plate 633. In an embodiment of the present invention, when driving the side guard plate 610 to rotate from the vertical state to the horizontal state, an operator can hold the handle 635 to push and pull, so that the lower acting plate 633 and the barrel seat portion 631 rotate, and then drive the side guard plate 610 to rotate to the horizontal state through the upper connecting portion 632.

[0039] In one embodiment, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, the lower acting plate 633 is perpendicular to the side guard plate 610. A magnetic plate member 634 is provided on the lower surface of the lower acting plate 633, and a magnetic strip 530 is provided on the outer wall of the side connecting plate 500. When the side guard plate 610 is in a horizontal state, the lower acting plate 633 is in a vertical state and the magnetic plate member 634 is in contact with the magnetic strip 530. In an embodiment of the present invention, after the side guard plate 610 is pulled open, since the lower acting plate 633 rotates to the vertical state and the magnetic plate member 634 is attached to the magnetic strip 530, a magnetic attraction force can be generated between the magnetic plate member 634 and the magnetic strip 530. Thus, the lower acting plate 633 can be firmly attached to the side connecting plate 500. The operator does not need to continue to act on the handle 635 and can free up his hands to pick up the connector plastic parts on the conveyor belt 130. And since the side guard plate 610 is in a horizontal state and is abutted against the side connecting plate 500 by the lower acting plate 633, the connector plastic parts can be placed on the side guard plate 610.

[0040] In one embodiment, as Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, a plurality of cross bar portions 520 are evenly distributed between two adjacent side connecting plates 500. The cross bar portions 520 horizontally pass through the inner side of the conveyor belt 130, and a roller portion is rotatably provided on each cross bar portion. The roller portion is in rolling contact with the upper surface of the inner ring of the conveyor belt 130. In an embodiment of the present invention, the setting of a plurality of roller portions can support the upper part of the conveyor belt 130, and can effectively prevent the upper part of the conveyor belt 130 from sagging due to the gravity of the connector plastic parts.

[0041] In one embodiment, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, a blanking guiding assembly 700 is provided at the blanking frame body 300. The blanking guiding assembly 700 includes a material guiding baffle 710 and a blanking chute 720. Both the material guiding baffle 710 and the blanking chute 720 are provided at the discharge end of the belt conveying component 100. The bottom of the material guiding baffle 710 is flush with the upper surface of the conveyor belt 130, and both sides of the material guiding baffle 710 are connected to the blanking frame body 300 through upper support arms 780. The top of the blanking chute 720 extends obliquely upward and is close to the outer surface of the discharge end of the conveyor belt 130. The side part of the blanking chute 720 is connected to the blanking frame body 300 through a lower support arm 770. In an embodiment of the present invention, the material guiding baffle 710 is an arc plate structure and protrudes toward the side away from the belt conveying component 100. The material guiding baffle 710 is made of rubber material, and both side edges of the material guiding baffle 710 have fastening frames. When the connector plastic part disengages from the discharge end of the conveyor belt 130 and contacts the surface of the material guiding baffle 710 under a certain inertia, the material guiding baffle 710 can block the connector plastic part from flying out of the end of the conveyor belt 130 and make the connector plastic part fall onto the blanking chute 720. The rubber material of the material guiding baffle 710 can buffer the inertial impact of the connector plastic part, and the connector plastic part slides from the blanking chute 720 onto the storage mechanism. The end of the blanking chute 720 facing the belt conveying component 100 has a plurality of avoidance notches 721. The setting of the avoidance notches 721 can avoid the interference between the movement of the material pushing unit 140 and the end of the blanking chute 720.

[0042] In one embodiment, as Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, two connecting rotating shaft parts 740 are rotatably arranged on the support rods of the blanking frame body 300. The end of the upper support arm 780 far from the material guiding baffle 710 is connected to the corresponding connecting rotating shaft part 740, and the end of the lower support arm 770 far from the blanking chute 720 is connected to the other corresponding connecting rotating shaft part 740. Transmission gears 790 are arranged on both of the two connecting rotating shaft parts 740, and a movable rod 750 which is in sliding fit with them is also arranged on the support rod wall of the blanking frame body 300. Both ends of the movable rod 750 have rack parts 760, and the two rack parts 760 are respectively meshed with the two transmission gears 790. The bottom of the blanking frame body 300 has an extended bottom plate part 310 extending to the lower side of the blanking chute 720, and the bottom of the blanking chute 720 is connected to the extended bottom plate part 310 through a supporting spring part 730. In the embodiment of the present invention, when the connector plastic part on the conveyor belt 130 is relatively long, the end of the connector plastic part will abut against the material guiding baffle 710 and push the material guiding baffle 710 open. Thus, the material guiding baffle 710 is stressed and rotates upward, and the connecting rotating shaft part 740 connected to the upper support arm 780 rotates. The connecting rotating shaft part 740 makes the connecting rotating shaft part 740 connected to the lower support arm 770 rotate through the meshing of the rack part 760 and the transmission gear 790 and the movement of the movable rod 750. Thus, the blanking chute 720 rotates upward, and the end of the connector plastic part can be supported, avoiding a large impact when the end of the connector plastic part directly falls into the inner side of the blanking chute 720. When the connector plastic part leaves the conveyor belt 130, the blanking chute 720 slowly rotates back to the initial state, effectively avoiding the connector plastic part from discharging with a large movement.

[0043] The above embodiments provide a device for preventing the fall of connector plastic parts during transportation. Among them, after the connector plastic parts are processed on the processing equipment, they fall from the upper side of the material receiving frame 410 into the interior of the material receiving frame 410. Since the material receiving elastic cushion layer 420 has a certain flexibility, it can prevent the connector plastic parts from directly colliding with the material receiving frame 410 and being damaged; after the material receiving frame 410 is impacted by the falling of the connector plastic parts, the material receiving frame 410 moves downward under the guidance of the guide rod 210 and compresses the buffer spring part 450. Thus, the buffer spring part 450 can play a buffering role. The downward movement of the material receiving frame 410 and the elasticity of the buffer spring part 450 can effectively buffer the impact generated by the falling of the connector plastic parts, reduce the rebound of the connector plastic parts, and the side wall of the material receiving frame 410 prevents the connector plastic parts from bouncing up and popping out of the belt conveying component 100 after falling; the connector plastic parts slide onto the conveyor belt 130 under the guidance of the arc-shaped side wall of the material receiving frame 410; the conveying motor 120 operates and drives the pulley part 110 to rotate, and the pulley part 110 drives the conveyor belt 130 thereon to move in a cycle. Thus, the conveyor belt 130 drives the connector plastic parts thereon to move towards the blanking frame body 300 to complete the transportation. The multiple pushing units 140 on the conveyor belt 130 can prevent the connector plastic parts from sliding on the conveyor belt 130 and affecting the transportation; the connector plastic parts will stay at the bottom of the material receiving frame 410, so the material receiving frame 410 bears the weight of the connector plastic parts and gradually approaches the conveyor belt 130; when the pushing unit 140 passes through the bottom of the material receiving frame 410, the top of the pushing unit 140 can extend into the interior of the material receiving frame 410 through the pushing notch 430. Thus, the top of the pushing unit 140 can take away the connector plastic parts in the material receiving frame 410 and move them to the upper surface of the conveyor belt 130; furthermore, the connector plastic parts can be transported in an orderly manner and prevented from popping out of the conveyor belt 130 due to falling and rebounding.
