Description

Technical Field

[0001] This utility model belongs to the technical field of plug-in housing feeding equipment, specifically relating to a plug-in housing feeding machine. Background Technology

[0002] A power strip is a multi-socket socket with a cord. Its structure includes a circuit board, contact springs, and a power strip shell. The power strip shell consists of a front shell and a bottom shell. In the power strip manufacturing process, the power strip shell is injection molded separately, and then the circuit board, contact springs, and power strip shell are assembled together to form a power strip.

[0003] The assembly of power strips is carried out by a power strip assembly machine. The key to ensuring the production efficiency and quality of power strips is to continuously supply the power strip shells to the assembly machine in a certain order.

[0004] In existing technologies, power strip housing feeding mainly relies on vibratory feeders and pusher machines. For example, patent CN105742935B discloses a power strip assembly machine's power strip switch base feeding device, including a feeding bracket, a vibratory feeder, a linear feeder, a linear vibrator, a vibrator bracket, a switch base switching assembly, and a switch base robotic arm. Although it can replace workers for automatic feeding and loading, its feeding vibration generates noise, and the vibration can easily lead to problems such as damage and cracking of the power strip housing. Utility Model Content

[0005] This utility model provides a power strip housing feeding machine to solve the problems of noise and damage to power strip housing caused by current vibration feeding.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a plug-in shell feeding machine, comprising a feeding component, a return component, a lifting component, a screening component, a flipping component and a discharging component that sequentially convey plug-in shells, wherein a guide plate is provided between the return component and the screening component, the screening component includes a screening belt and a blowing structure, the blowing structure transfers the improperly arranged plug-in shells from the screening belt to the return component;

[0007] The lifting assembly includes a lifting belt, several trays protruding from the surface of the lifting belt, and a hopper. The hopper has a bottom plate inclined toward the lifting belt. As the lifting belt rotates, insert shells are randomly arranged one by one between adjacent trays in the hopper and move to the screening assembly with the lifting belt.

[0008] Specifically, the feeding component is a feeding hopper or a material box.

[0009] Specifically, the screening component includes a material discharge protective cover.

[0010] Specifically, the hopper includes side plates disposed on both sides of the bottom plate, and the side plates extend along the running direction of the lifting belt to form baffles located on both sides of the lifting belt.

[0011] Specifically, the trays are parallel to each other, the distance between adjacent trays is greater than the width of the power strip housing and less than the height of the power strip housing, and the distance between adjacent trays is less than the sum of the widths of the two power strip housings.

[0012] Specifically, the height of the pallet protruding above the conveyor belt is equal to the thickness of the power strip housing.

[0013] Specifically, the screening component further includes an outer baffle and an inner baffle for guiding the socket housing, wherein the inner baffle has a notch at a position opposite to the guide plate.

[0014] Specifically, the flipping assembly includes a visual inspection camera, a robotic arm, and a flipping structure. The visual inspection camera is used to identify the front and back of the power strip housing, the robotic arm is used to pick up, place, and transfer the power strip housing, and the flipping structure is used to flip the power strip housing and adjust its front and back orientation.

[0015] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0016] 1. A lifting belt is used instead of a vibratory plate and pusher to achieve stable, vibration-free feeding and avoid damage to the power strip housing caused by vibration.

[0017] 2. By setting the spacing between adjacent pallets and the height of the pallets protruding above the surface of the lifting belt, the stacking of the power strip shells is restricted, ensuring that the power strip shells are fed one by one, and preventing the subsequent arrangement disorder caused by the mutual pushing between the power strip shells.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1As shown, a power strip housing feeder includes a feeding assembly, a return assembly 20, a lifting assembly 30, a screening assembly 40, a tilting assembly 50, and a discharge assembly that sequentially convey power strip housings 90. A guide plate 70 is provided between the return assembly 20 and the screening assembly 40, and the power strip housings 90 discharged from the screening assembly 40 enter the return assembly 20 through the guide plate 70. The feeding assembly is a feeding bin 10, and the discharge assembly includes a discharge belt 60.

[0031] like Figure 2 and Figure 3 As shown, the feed hopper 10 is used to collect the power strip shells 90 discharged from the previous production process. The feed hopper 10 includes a material frame 11 with an opening at the top and a feed belt 12 set at the bottom of the material frame 11. The power strip shells 90 discharged from the previous process enter through the opening at the top of the material frame 11, fall to the left end of the feed belt 12, and move to the right with the feed belt 12 until they fall from the right end of the feed belt 12.

[0032] like Figure 4 As shown, the recirculation assembly 20 includes a recirculation belt 21 located below the feed belt 12 and recirculation baffles 22 located on both sides of the recirculation belt 21. The connector housing 90 falling from the right end of the feed belt 12 lands on the left end of the recirculation belt 21, and then travels with the recirculation belt 21 to its right end until it falls off. The recirculation belt 21 operates at a faster speed than the feed belt 12, and the connector housing 90 falling from the feed belt 12 is relatively evenly distributed on the recirculation belt 21.

[0033] like Figure 5As shown, the lifting assembly 30 includes a lifting belt 31, several support plates 32 protruding from the surface of the lifting belt 31, and a hopper 33. With the running direction of the lifting belt 31 as the longitudinal direction and the direction perpendicular to the running direction of the lifting belt 31 as the transverse direction, the support plates 32 are parallel to each other and are all transversely arranged on the lifting belt 31. The distance between adjacent support plates 32 is greater than the width of the plug-in housing 90 and less than the height of the plug-in housing 90. Simultaneously, the distance between adjacent support plates 32 is less than the sum of the widths of two plug-in housings 90. This spacing design ensures that, longitudinally, there is only one plug-in housing 90 between adjacent support plates 32. The height of the support plate 32 protruding from the conveyor belt is equal to the thickness of the plug-in housing 90, ensuring that the support plate 32 can support one plug-in housing 90 covering the surface of the lifting belt 31, and only supports one plug-in housing 90, avoiding the stacking of plug-in housings 90. The hopper 33 includes a bottom plate (not shown in the figure), two side plates 331 and a front plate 332. The bottom plate is inclined toward the lifting belt 31. The plug shell 90 inside the hopper 33 slides toward the lifting belt 31 under the action of gravity. The front plate 332 is fixedly connected to the side of the bottom plate away from the lifting belt 31. A side plate 331 is fixedly connected to each side of the front plate 332. The bottom of the side plate 331 is fixedly connected to the edge of the bottom plate. The side plate 331 extends along the running direction of the lifting belt 31 to form baffles on both sides of the lifting belt 31 to prevent the plug shell 90 from falling off the edges of the lifting belt 31. The lifting belt 31 has a feed end and an output end that are arranged opposite to each other. The feed end, together with the hopper 33, forms a cavity for accommodating the plug shell 90. The cavity is located below the height of the return belt 21. The plug shell 90 falling from the right end of the return belt 21 enters the cavity. In the hopper 33, the plug shell 90 is randomly arranged one by one between adjacent trays 32, and moves with the lifting belt 31 to the output end of the lifting belt 31 until it falls off.

[0034] like Figure 1 and Figure 6As shown, the screening assembly 40 includes a screening belt 41, a blow-off structure 42, a discharge protective cover 43, and an outer baffle 44 and an inner baffle 45 for guiding the plug-in housing 90. The right end of the screening belt 41 is lower than the output end of the lifting belt 31, and the plug-in housing 90 output from the lifting belt 31 falls to the right end of the screening belt 41. The discharge protective cover 43 is fixed in front of the output end of the lifting belt 31. During the fall of the plug-in housing 90, it is restricted by the discharge protective cover 43. There is a gap between the discharge protective cover 43 and the lifting belt 31. This gap is larger than the width of the plug-in housing 90 to ensure that the gap is large enough for the plug-in housing 90 to fall. The screening belt 41 is provided with an inner crossbeam 47 and an outer crossbeam 48 on both sides. An inner baffle 45 is fixedly connected to the inner crossbeam 47. The inner baffle 45 has a notch at the position opposite to the guide plate 70. A blow-off structure 42 and several support rods 46 are fixedly connected to the outer crossbeam 48. An outer baffle 44 is suspended above the screening belt 41. The outer baffle 44 and the inner baffle 45 form a channel for guiding the plug shell 90. The end of the support rod 46 away from the outer crossbeam 48 is fixedly connected to the outer baffle 44 to support the outer baffle 44 and prevent it from deforming. The blow-off structure 42 is an air pipe connected to the air supply system. The air pipe is flexible and has a nozzle at its end. The position of the blow-off structure 42 is opposite to that of the guide plate 70. When the misaligned insert shells 90 on the screening belt 41 pass through the gap, they are impacted by the gas ejected from the nozzle and enter the return belt 21 through the guide plate 70. The height of the return belt 21 is lower than that of the screening belt 41. The misaligned insert shells 90 are those arranged horizontally and stacked together. The neatly arranged insert shells 90 move with the screening belt 41 to the left end of the screening belt 41.

[0035] like Figure 7 As shown, the flipping assembly 50 includes a vision inspection camera 51, a robotic arm 52, and a flipping structure 53. The vision inspection camera 51 is used to identify the front-back direction and the front and back sides of the power strip housing 90. If the front-back direction and the front and back sides of the power strip housing 90 are correct, the robotic arm 52 grabs the power strip housing 90 at the left end of the screening belt 41 and places it on the discharge belt 60. If the front-back direction or the front and back sides of the power strip housing 90 are incorrect, the robotic arm 52 grabs the power strip housing 90 at the left end of the screening belt 41 and places it on the flipping structure 53. The flipping structure 53 flips the power strip housing 90 to adjust the front-back direction and the front and back sides until the front-back direction and the front and back sides are correct. Then the robotic arm 52 grabs the power strip housing 90 on the flipping structure 53 and places it on the discharge belt 60.

[0036] like Figure 1 and Figure 6As shown, the feeding belt 12, return belt 21, lifting belt 31, screening belt 41, and discharge belt 60 all include an annular belt, a drive shaft, a drive shaft, and a drive motor. A crossbeam, a drive shaft, and several drive shafts are arranged sequentially between the two crossbeams on both sides of the annular belt. The output shaft of the drive motor is connected to the drive shaft. The drive shafts are connected to the drive shaft and adjacent drive shafts via chains, racks, or belts. Both ends of the drive shaft and the drive shaft are rotatably connected to the crossbeams via bearings, and both the drive shaft and the drive shaft are located within the annular belt. The drive motor drives the drive shaft to rotate, which in turn drives the drive shaft to rotate, causing the annular belt to run. Preferably, a belt tensioning device can be installed on the crossbeam. In the screening belt 41, the crossbeams on both sides of the annular belt are the inner crossbeam 47 and the outer crossbeam 48.

[0037] like Figure 8 As shown, an equipment housing 80 is provided on the outer periphery of the power strip housing feeder, and a vision inspection camera 51 is mounted on the top plate of the equipment housing 80.

[0038] In a preferred embodiment of this example, the feeding component is a material bin, which is used for manual feeding.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein, and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of this utility model.
