Description

Technical Field

[0001] This invention relates to the field of flow channel plate lower body production technology, specifically to a multi-station synchronous automatic feeding device for flow channel plate lower body inserts. Background Technology

[0002] As a core component in fluid control systems, automotive parts, and home appliances, the lower part of the flow channel plate is generally produced using an insert injection molding process. This requires pre-inserting metal inserts such as knurled nuts into the injection mold cavity, and then using injection molding to integrate the inserts with the plastic matrix to meet the product's functional requirements such as threaded connection and enhanced strength.

[0003] Currently, the injection molding production of runner plate lower body inserts mostly adopts manual or semi-automatic feeding methods: manual feeding requires operators to place the inserts one by one into the mold positioning pins, which is labor-intensive, has extremely low production efficiency, and has problems such as missing, misplacement, and misaligned inserts, directly leading to a high product scrap rate; existing semi-automatic equipment is mostly a single-station feeding structure, where insert feeding and robotic arm unloading must be performed sequentially, resulting in a large amount of waiting time for the injection molding machine and an equipment utilization rate of less than 50%. At the same time, most equipment has a single function, only able to complete the insert feeding action, and the unloading of the injection molded finished product still requires manual or additional unloading robotic arms, resulting in low equipment integration, large footprint, and high cost.

[0004] In addition, the existing feeding robot's gripper structure has poor versatility and cannot simultaneously meet the needs of external clamping of metal inserts and internal gripping of injection-molded finished products; during the unloading process, the gripper is prone to hard scratches on the inner wall of the insert, which damages the product's precision; the positioning accuracy of simultaneous feeding of multiple inserts is difficult to guarantee, and it cannot be adapted to flow channel plate lower body products with different hole distributions, which seriously restricts the large-scale, high-quality production of flow channel plate lower bodies. Summary of the Invention

[0005] The purpose of this invention is to solve the above problems by providing a multi-station synchronous automatic feeding device for the lower body insert of the flow channel plate.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0011] Furthermore, the loading robot includes a large arm fixedly installed at the bottom of the telescopic end of the Z-axis lifting cylinder. A swing arm plate is rotatably installed at the bottom of the large arm. A sliding opening is provided through the inside of the swing arm plate.

[0012] Furthermore, the mechanical gripper assembly includes a slide, a gripper sleeve, an outer sleeve, an inner shaft, and a drive bevel gear. The slide is slidably connected in the slide opening. The gripper sleeve is suspended from the bottom of the slide via an L-shaped connector. Two sets of variable grippers are welded to the outer side of the gripper sleeve. The outer sleeve is sleeved on the outer side of the gripper sleeve. The inner shaft passes through the gripper sleeve. A lower bevel gear is provided at the top of the outer sleeve, and a lever one is provided at the bottom of the outer sleeve. An upper bevel gear is provided at the top of the inner shaft, and a lever two is provided at the lower end of the inner shaft. Lever two is at the same height as lever one and is attached to the outer surface of the variable grippers. The drive bevel gear is mounted on the slide and meshes between the upper and lower bevel gears.

[0013] Furthermore, the elastic force of the variable grippers when they unfold inside the insert is less than the sum of the weights of the lower body of the flow channel plate and the insert.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1, as Figures 1-8 As shown, a multi-station synchronous automatic feeding device for runner plate lower body inserts includes a runner plate lower body injection molding machine 4. The top of the runner plate lower body injection molding machine 4 is provided with an X-axis linear slide rail module 41. A Y-axis linear slide rail module 42 is provided on the X-axis linear slide rail module 41. A Z-axis lifting cylinder 43 is provided on the Y-axis linear slide rail module 42. A feeding robot 6 is provided at the bottom of the telescopic end of the Z-axis lifting cylinder 43.

[0032] The right side of the injection molding machine 4 for the lower part of the flow channel plate is provided with an insert feeding line 3 and the left side is provided with an unloading line 5. The X-axis linear slide rail module 41 spans the insert feeding line 3 and the unloading line 5. The insert feeding line 3 includes a frame 31 set on the ground. The top of the frame 31 is provided with a vibratory feeder 32. The outlet of the vibratory feeder 32 is provided with a gripping component that can grip the insert 2 individually. The left side of the vibratory feeder 32 is provided with a rotatable base 37. The base 37 is provided with two sets of self-rotating feeding discs 38. The top of each of the two sets of feeding discs 38 is equipped with several feeding rods 39. The positions of the feeding rods 39 correspond to the positions of the insert holes on the lower part of the flow channel plate 1. The gripping component can grip the vertical insert 2 and put it on the feeding rod 39.

[0033] The loading robot 6 can grab the insert 2 sleeved on the loading rod 39 and put it into the injection mold of the runner plate lower body injection molding machine 4, and the loading robot 6 can place the injection molded runner plate lower body 1 horizontally on the unloading line 5.

[0034] The top of the feeding rod 39 is tapered.

[0035] The insert 2 used in the lower body 1 of the flow channel plate of this invention is actually a knurled nut. Therefore, the vibratory feeder 32 is suitable for feeding knurled nuts (it is an existing conventional nut vibratory feeder, and no specific structural limitation is made in this invention; it is commercially available). All rotation drives in this invention use servo motors, which can precisely control the rotation angle and are self-locking when powered on.

[0036] Processing flow: (1) Insert 2 feeding: Vibrating plate 32 vertically conveys irregular insert 2 to its outlet, then the gripping component grips insert 2 and puts insert 2 on the feeding rod 39. Then the gripping component grips another insert 2. The feeding plate 38 near vibrating plate 32 rotates. The feeding plate 38 causes another feeding rod 39 to rotate to the feeding position. After all the feeding rods 39 on one feeding plate 38 are fed, the base plate 37 is controlled to rotate. The base plate 37 drives the two feeding plates 38 to switch positions. Then all the feeding rods 39 on the other feeding plate 38 are fed. After the feeding is completed, the base plate 37 drives the two feeding plates 38 to rotate to the discharge state. According to the attached Figure 3 As shown, this is the fully loaded state. Rotating 90° from this position results in the unloading state. This provides the loading robot 6 with sufficient gripping space and prevents structural interference. At this point, the X-axis linear slide rail module 41 moves the loading robot 6 directly above the loading tray 38. The Z-axis lifting cylinder 43 lowers the loading robot 6 to grip all the inserts 2. The Z-axis lifting cylinder 43 then raises the loading robot 6 to remove the inserts 2 from the loading rod 39, completing the loading of the inserts 2.

[0037] (2) Injection Molding Loading: The X-axis linear slide rail module 41 drives the loading robot 6 to move to the position of the injection molding machine 4 under the runner plate and to the position corresponding to the mold. The Z-axis lifting cylinder 43 drives the loading robot 6 to descend. The loading robot 6 rotates to make the insert 2 horizontal and align it with the insert positioning post on the mold (this is the existing mold structure, and it is not limited in this invention, or other insert positioning parts are also acceptable, generally positioning posts, used to position and block the insert 2 to ensure that the injection liquid does not enter the interior of the insert 2). The Y-axis linear slide rail module 42 drives the loading robot 6 to approach the mold horizontally and put the insert 2 on the insert positioning post on the mold to complete the injection molding loading.

[0038] (3) Unloading: The mold in the injection molding machine 4 closes, so that the insert 2 is integrally injected into the lower body of the runner plate 1. After the mold has completely cooled and opened, the loading robot 6 is inserted into the insert 2 to grasp the lower body of the runner plate 1. After the lower body of the runner plate 1 is injected, as follows: Figure 1 As shown in the vertical position, the X-axis linear slide rail module 41 then drives the loading robot 6 to move to the unloading line 5. The loading robot 6 rotates the lower body 1 of the flow channel plate to a horizontal position and places it on the unloading line 5 to complete the unloading.

[0039] This invention requires no manual intervention throughout the entire process, automating the entire loading and unloading process of the lower part of the flow channel plate 1 during injection molding, which greatly improves production efficiency.

[0040] In embodiment two, based on the above embodiment, the gripping component includes a bracket 33 fixedly installed on the top of the frame 31. The bracket 33 is located at the discharge port of the vibratory feeder 32. A horizontal moving cylinder 34 is fixedly installed on the top of the bracket 33. A vertical moving cylinder 35 is installed on the telescopic end of the horizontal moving cylinder 34. An insert clamp 36 is fixedly installed at the bottom of the telescopic end of the vertical moving cylinder 35. Two sets of elastic C-shaped clamps are provided on the insert clamp 36. The two sets of elastic C-shaped clamps are configured to conform to the insert 2.

[0041] This embodiment describes the specific gripping component structure, which mainly uses insert 2 for contour clamping. The horizontal moving cylinder 34 drives the insert clamp 36 to approach the insert 2, and the elastic C-shaped clamping piece presses against the insert 2. The insert 2 first causes the elastic C-shaped clamping piece to open, and then the elastic C-shaped clamping piece wraps around the insert 2 under its own elastic force. The upper and lower elastic C-shaped clamping pieces are respectively clamped in the two annular recesses of the insert 2 to achieve efficient and stable clamping. After gripping, the horizontal moving cylinder 34 drives the insert 2 to move directly above the feeding rod 39, and the vertical moving cylinder 35 drives the insert 2 to descend through the insert clamp 36. The insert 2 is then sleeved on the feeding rod 39, completing the gripping and feeding process.

[0042] In embodiment three, based on the above embodiments, the loading robot 6 includes a large arm 61 fixedly installed at the bottom of the telescopic end of the Z-axis lifting cylinder 43. A swing arm plate 62 is rotatably installed at the bottom of the large arm 61. A sliding opening is provided through the inside of the swing arm plate 62. Several mechanical claw assemblies 7 are slidably connected inside the sliding opening. The mechanical claw assemblies 7 are correspondingly arranged with the loading rod 39. The mechanical claw assemblies 7 can grasp the insert 2 by following the shape.

[0043] The mechanical gripper assembly 7 includes a slide 71, a gripper sleeve 73, an outer sleeve 74, an inner shaft 75, and a drive bevel gear 76. The slide 71 is slidably connected in the slide opening. The gripper sleeve 73 is suspended from the bottom of the slide 71 by an L-shaped connector. Two sets of variable grippers 731 are welded to the outside of the gripper sleeve 73. The outer sleeve 74 is sleeved on the outside of the gripper sleeve 73. The inner shaft 75 passes through the gripper sleeve 73. A lower bevel gear 741 is provided at the top of the outer sleeve 74, and a lever 742 is provided at the bottom of the outer sleeve 74. An upper bevel gear 751 is provided at the top of the inner shaft 75, and a lever 752 is provided at the lower end of the inner shaft 75. The lever 752 and the lever 742 are at the same height and are attached to the outer surface of the variable grippers 731. The drive bevel gear 76 is provided on the slide 71 and meshes between the upper bevel gear 751 and the lower bevel gear 741.

[0044] Two sets of adjusting discs 63 are rotatably installed on the top of the swing arm plate 62. The inside of the adjusting disc 63 is provided with an arc-shaped guide groove. The top of the slide 71 is provided with an adjusting slide column 72, which passes through the arc-shaped guide groove.

[0045] The chassis 37, the feeding plate 38, the swing arm plate 62, the drive bevel gear 76, and the adjustment plate 63 are all driven by servo motors.

[0046] The elastic force of the several variable grippers 731 when they unfold inside the insert 2 is less than the sum of the weights of the lower body 1 of the flow channel plate and the insert 2.

[0047] This embodiment describes the specific structure of the feeding robot 6.

[0048] Insert 2 gripping: The X-axis linear slide rail module 41 drives the loading robot 6 to move directly above the loading plate 38. The Z-axis lifting cylinder 43 drives the loading robot 6 to descend. At this time, the mechanical claw assembly 7 is in a center-closed state. The mechanical claw assembly 7 descends to between the loading rods 39. Then, the servo motor controls the adjustment plate 63 to rotate. The adjustment plate 63 drives the mechanical claw assembly 7 to unfold outward through the arc-shaped guide groove and the adjustment slide column 72. At this time, the variable gripper 731 is in an unfolded C-shaped state. The variable gripper 731 presses against the insert 2, similar to an elastic C-shaped clamp, and clamps the insert 2 in a contoured manner. Then, the Z-axis lifting cylinder 43 drives the loading robot 6 to rise and pull the insert 2 away from the loading rod 39. At this time, the insert 2 is in a vertical state.

[0049] Injection Molding Loading: The X-axis linear slide rail module 41 drives the loading robot 6 to move to the position of the injection molding machine 4 under the runner plate and to the position corresponding to the mold. The Z-axis lifting cylinder 43 drives the loading robot 6 to descend. The swing arm plate 62 on the loading robot 6 rotates 90° under the action of the servo motor, so that the insert 2 is in a horizontal state and aligned with the insert positioning post on the mold. The Y-axis linear slide rail module 42 drives the loading robot 6 to move horizontally closer to the mold. The loading robot 6 puts the insert 2 on the insert positioning post on the mold. After the insertion is completed, the mechanical claw assembly 7 closes to the center again. The variable gripper 731 moves away from the insert 2. The movement trajectory of the variable gripper 731 is perpendicular to the positioning post, which can stably remove the insert 2.

[0050] Material feeding: The mold in injection molding machine 4 closes, so that insert 2 is integrally injected into the lower body of the runner plate 1. After the mold is completely cooled and opened, the mechanical claw assembly 7 deforms, and drives the drive bevel gear 76 to rotate forward through the servo motor. The drive bevel gear 76 drives the upper bevel gear 751 and the lower bevel gear 741 to rotate synchronously in opposite directions. The upper bevel gear 751 and the lower bevel gear 741 drive the outer sleeve 74 and the inner shaft 75 to rotate synchronously in opposite directions. The lever 1 742 and the lever 2 752 rotate synchronously in opposite directions, and the two are separated from the middle. The variable gripper 731 presses against the gripper sleeve 73. At this time, the overall outer diameter of the mechanical gripper assembly 7 is smaller than the inner diameter of the insert 2, allowing it to be directly inserted into the insert 2. Then, the adjusting plate 63 causes the mechanical gripper assembly 7 to unfold outward, aligning it with the insert 2. The Y-axis linear slide rail module 42 drives the mechanical gripper assembly 7 to insert into the insert 2. After insertion, the drive bevel gear 76 is reversed, causing the variable gripper 731 to unfold inside the insert 2, thus gripping the lower part of the flow channel plate 1. After the lower part of the flow channel plate 1 is injection molded, as... Figure 1 As shown in the vertical position, it is stably hung on the mechanical claw assembly 7. Then, the X-axis linear slide rail module 41 drives the loading robot 6 to move to the unloading line 5. The servo motor drives the swing arm plate 62 to rotate quickly to the horizontal. The swing arm plate 62 makes the lower body of the flow channel plate 1 rotate quickly to the horizontal position. Since in this embodiment, the elastic force of several variable grippers 731 when they are unfolded inside the insert 2 is less than the sum of the weights of the lower body of the flow channel plate 1 and the insert 2, the effect of gravity is the greatest when the lower body of the flow channel plate 1 is horizontal. The friction between the variable grippers 731 and the insert 2 only plays a buffering role, so that the lower body of the flow channel plate 1 slowly falls onto the unloading line 5 under the action of gravity, completing the unloading.

[0051] Both the variable gripper 731 and the elastic C-type clamping plate are made of spring steel, which has good hardenability, high elasticity, moderate strength, low price, and excellent machinability. Heat treatment process: oil quenching at 830℃ + tempering at 400℃, with hardness controlled at HRC42-48.

[0052] In this embodiment, the variable gripper has a hardness of 731 HRC42-45: it has a gentle elasticity and is suitable for gravity-cushioned feeding.

[0053] Example 4, based on the above examples, further includes a plurality of variable grippers 731 whose elastic force when unfolded inside the insert 2 is greater than the sum of the weights of the lower body 1 of the flow channel plate and the insert 2.

[0054] This embodiment employs another method. Since the combined elastic force of the variable grippers 731 when unfolded inside the insert 2 is greater than the combined weight of the lower flow channel plate 1 and the insert 2, the lower flow channel plate 1 remains stably clamped even when it is horizontal. At this point, the drive bevel gear 76 is rotated forward, and levers 742 and 752 press the variable grippers 731 against the gripper sleeve 73 again. While this design adds more steps compared to the previous embodiment, it avoids scratching the inner wall of the insert 2 and provides more stable and controllable material feeding.

[0055] In this embodiment, the variable gripper has a hardness of 731 HRC45-48: it has strong elasticity and is suitable for active shrinkage feeding.

[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
