Description

Technical Field

[0001] This invention relates to the field of eyebrow trimming blade assembly technology, and more specifically, to a blade feeding device and blade storage assembly for an eyebrow trimming blade assembly line. Background Technology

[0002] An eyebrow trimmer, also known as an eyebrow razor, is a beauty tool, usually made of high-quality plastic and blades.

[0003] The manufacturing process of eyebrow trimmers involves multiple processing steps at different locations, necessitating multiple transfer mechanisms on the assembly line. Given the thinness of the blade, existing transfer mechanisms primarily utilize air suction for material handling. This involves air vents at the contact points. When the transfer mechanism reaches the contact point, the negative pressure generated by the air suction system adheres the trimmer to that point until it reaches the next processing unit. Depressurization then allows the trimmer to detach under its own weight. However, traditional loading equipment suffers from inconsistent adhesion points during transfer, resulting in variations in the trimmer's orientation. Since the processing requires locating the trimmer at its current processing point, secondary adjustments are necessary after each trimmer reaches its processing location, impacting automated processing efficiency. Furthermore, the varying adjustment ranges between trimmer states increase the difficulty of these secondary adjustments. Summary of the Invention

[0004] The purpose of this invention is to provide a blade feeding device and a blade storage assembly for an eyebrow trimming blade assembly line, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one objective of this invention is to provide a blade feeding device for an eyebrow trimming blade assembly line, comprising a material picking block, a material straightening plate, a transverse picking arm, a processing plate, and a longitudinal picking arm. The material picking block has suction heads at both ends of its side for placing eyebrow trimming blades. The suction heads, the transverse picking arm, and the longitudinal picking arm are all equipped with pneumatic suction components for adsorbing the eyebrow trimming blades to their contact positions. The transverse picking arm and the longitudinal picking arm are each equipped with a pneumatic slide rail at their top ends.

[0006] The material straightening plate has a top groove at its top end, and a partition plate is slidably disposed inside the top groove. The partition plate has straightening grooves on both sides of its top end for accommodating different eyebrow trimming blades. The partition plate moves up and down along the top end of the material straightening plate. An air supply component is disposed inside the material straightening plate, and a transverse guide groove is disposed on both sides of the partition plate to connect the straightening grooves with the air supply component. Side plates are disposed at both ends of the partition plate, and a longitudinal guide groove is disposed on the side of the side plate near the transverse guide groove to maintain communication with the air supply component.

[0007] During the process of the horizontal material handling arm adsorbing the eyebrow trimming blade and moving it downwards along the material straightening plate, the pressure generated by the downward pressure drives the partition plate to move downwards synchronously and applies pressure to the air supply component. In the initial stage, as the bottom end of the side plate moves from the highest point to the middle position of the top groove, the air supply component is connected to the inner ends of the two side plates. Gas is blown through the longitudinal guide groove to the inner end of the straightening groove at the corresponding position, blowing the eyebrow trimming blade placed in the inner end of the straightening groove towards the opposite side of the side plate. In the final stage, as the bottom end of the side plate moves from the middle position of the top groove to the lowest point, the air supply component is connected to the inner ends of the two horizontal guide grooves. The thrust generated by the gas flow blows the eyebrow trimming blade placed in the inner end of the straightening groove towards the opposite side of the horizontal guide groove, adjusting it to the diagonal area of ​​the inner end of the straightening groove.

[0008] As a further improvement to this technical solution, the air supply assembly includes an airbag and exhaust pipes disposed on both sides of the bottom end of the airbag. Each corner of the bottom end of the partition plate is provided with a squeezing rod, and the bottom end of each squeezing rod is in contact with the top end of the airbag. The exhaust pipe is in communication with the inner end of the airbag. An air collection chamber is opened on the inner side of the material straightening plate. The top end of the exhaust pipe extends into the inner end of the air collection chamber and is in communication with it. Airbags are opened on both sides of the inner wall of the top groove near the upper position and are in communication with the inner end of the air collection chamber. Air inlets are opened on the sides of the two side plates at positions aligned with the airbags. The air inlets, the longitudinal guide groove, and the airbags are in communication. Connecting grooves are opened on both sides of the inner wall of the top groove near the middle position and are in communication with the inner end of the air collection chamber. A transverse guide groove is opened on the inner wall of the straightening groove near the connecting groove.

[0009] As a further improvement to this technical solution, the bottom cross-sectional dimensions of the transverse material picking arm are consistent with the top cross-sectional dimensions of the partition plate. After the bottom end of the transverse material picking arm contacts the top end of the partition plate, it forms a sealed chamber with the straightening groove to accommodate the eyebrow trimmer blade, thereby limiting the eyebrow trimmer blade in the blowing state. The height of the sealed chamber is less than the height of the eyebrow trimmer blade in the upright state.

[0010] As a further improvement to this technical solution, both the transverse guide groove and the longitudinal guide groove have inclined cross-sections, and the height of the port of the transverse guide groove and the longitudinal guide groove near the correction groove is lower than the height of the port of the other side.

[0011] As a further improvement to this technical solution, the inner end of the side plate is provided with a cavity that communicates with the longitudinal guide groove and the air inlet. An inner block is slidably disposed in the inner end of the cavity. Buffer components are provided on both sides of the top of the inner block. The force applied by the buffer components overcomes the weight of the inner block itself, keeping the inner block suspended in the middle position of the inner end of the cavity. The side position of the inner block covers the longitudinal guide groove located at the inner end port of the cavity.

[0012] As a further improvement to this technical solution, the buffer assembly includes an outer rod and a limiting spring sleeved on the outside of the outer rod. A pair of collars are provided at the top of the side plate. The two outer rods respectively pass through the cavity and extend into the inner side of the collars at corresponding positions, and the limiting spring is located inside the collars.

[0013] The second objective of this invention is to provide a blade storage assembly for use with a blade feeding device in an eyebrow trimming blade assembly line. This assembly includes a storage platform and a guide plate mounted on the top side of the storage platform. A picking block is mounted on the bottom side of the guide plate, and a slide rail connects the bottom of the picking block to the bottom of the storage platform. Both ends of the guide plate have storage slots for stacking eyebrow trimming blades. Two suction heads are positioned opposite the two storage slots, and the cross-sectional dimensions of the suction heads are consistent with those of the storage slots. A picking component is located near the bottom of the storage slot. After the suction head moves to the corresponding position inside the storage slot, it works in conjunction with the picking component and the air suction component built into the suction head to pick up a single eyebrow trimming blade.

[0014] As a further improvement to this technical solution, the material handling component includes a limiting block, the side of which is aligned with the opposite side of the adsorption head, and the limiting block is in a plug-in fit with the inner end of the storage tank, with a reset spring connected to the plug-in position.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] In this eyebrow trimmer assembly line, the blade feeding equipment and storage assembly use a transverse feeding arm to push a partition plate to pressurize the air supply component. During the movement of the partition plate, the conduction state of the air supply component is changed, and the gas generated by the extrusion is discharged in stages to the inner ends of the two side plates. This gas, along with the longitudinal guide grooves on the side plates, is discharged outwards, blowing the eyebrow trimmer blades that have fallen into the straightening groove, causing them to move away from the side plates and completing one straightening operation. Subsequently, the partition plate changes position, and the two transverse guide grooves are connected to the air supply component. The gas generated by the extrusion will be discharged outwards along the transverse guide grooves, blowing the eyebrow trimmer blades that are in contact with the side of the straightening groove a second time. This automatically corrects the position of the eyebrow trimmer blades during processing, reducing the number of operation steps and improving feeding efficiency. Attached Figure Description

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0034] Please see Figure 1 As shown, one of the objectives of this invention is to provide a blade feeding device for an eyebrow trimming blade assembly line, comprising a picking block 10, a material straightening plate 20, a transverse picking arm 30, a processing plate 40, and a longitudinal picking arm 50. The picking block 10 has suction heads 110 at both ends of its side for placing eyebrow trimming blades. The suction heads 110, transverse picking arm 30, and longitudinal picking arm 50 are all equipped with pneumatic suction components for adsorbing the eyebrow trimming blades to their contact positions. The transverse picking arm 30 and the longitudinal picking arm 50 are each equipped with pneumatic slide rails at their top ends for driving the transverse picking arm 30 to slide horizontally above the material straightening plate 20, adsorbing the eyebrow trimming blades placed at the top of the suction head 110 to the bottom of the material straightening plate 20. The longitudinal picking arm 50 is driven to slide horizontally above the processing plate 40, adsorbing the eyebrow trimming blades placed at the top of the material straightening plate 20 to the top of the processing plate 40.

[0035] The top of the material straightening plate 20 has a top groove 240, and a partition plate 210 is slidably arranged inside the top groove 240. Both sides of the top of the partition plate 210 have straightening grooves 212 for accommodating different eyebrow trimming blades. The partition plate 210 moves up and down along the top of the material straightening plate 20. An air supply component is arranged inside the material straightening plate 20, and both sides of the partition plate 210 have transverse guide grooves 211 that connect the straightening grooves 212 and the air supply component. Both ends of the partition plate 210 have side plates 220, and the side plate 220 near the transverse guide groove 211 has a longitudinal guide groove 221 that communicates with the air supply component.

[0036] During the process of the horizontal picking arm 30 adsorbing the eyebrow trimming blade and moving it downward along the material straightening plate 20, the pressure generated by the downward pressure drives the partition plate 210 to move downward synchronously and applies pressure to the air supply component. In the initial stage, as the bottom end of the side plate 220 moves from the highest point to the middle position of the top groove 240, the air supply component is connected to the inner ends of the two side plates 220. The gas is blown through the longitudinal guide groove 221 to the inner end of the corresponding straightening groove 212, blowing the eyebrow trimming blade placed in the inner end of the straightening groove 212 towards the opposite side of the side plate 220. In the final stage, as the bottom end of the side plate 220 moves from the middle position of the top groove 240 to the lowest point, the air supply component is connected to the inner ends of the two horizontal guide grooves 211. The thrust generated by the gas flow blows the eyebrow trimming blade placed in the inner end of the straightening groove 212 towards the opposite side of the horizontal guide groove 211, adjusting it to the diagonal area of ​​the inner end of the straightening groove 212.

[0037] In practical use, during the process of feeding eyebrow trimmer blades, firstly, the two eyebrow trimmer blades are respectively adsorbed by the suction heads 110 set at both ends of the side of the material taking block 10 in conjunction with the air suction component. The air suction component uses an air pump to draw air into the inner end of the material taking block 10 through the air hole opened at the top of the suction head 110. When it comes into contact with the eyebrow trimmer blade, a negative pressure is generated at the contact position, so that the suction head 110 is attached to the top of the suction head 110, thus completing the position fixation.

[0038] After completing the processing work at the current position, by Figures 6-7 As shown, the horizontal picking arm 30 slides horizontally along the corresponding pneumatic slide rail to a position directly above the suction head 110, and then slides downwards to contact the eyebrow trimming blade at the top of the suction head 110. At this time, the air suction component built into the suction head 110 stops operating, and the air suction component built into the horizontal picking arm 30 starts. The negative pressure generated causes the eyebrow trimming blade to be adsorbed to the contact position at the bottom of the horizontal picking arm 30. However, because the bottom suction surface of the horizontal picking arm 30 is large, the eyebrow trimming blade is easily misaligned during the adsorption process, that is, it cannot remain parallel to the bottom surface of the horizontal picking arm 30. At this time, the bottom of the horizontal picking arm 30 will... The tilted eyebrow trimmer blade moves along the pneumatic slide rail from above the suction head 110 to directly above the material straightening plate 20. At this time, the bottom surface of the horizontal picking arm 30 is aligned with the top of the partition plate 210 and moves downward to gradually contact the top of the partition plate 210. After the two complete the contact work, the horizontal picking arm 30 in the downward state will simultaneously drive the partition plate 210 to slide from top to bottom along the inner end of the top groove 240. At the same time, the air suction component built into the horizontal picking arm 30 stops operating. The eyebrow trimmer blade, which loses the negative pressure, will fall into the inner end of the straightening groove 212 at the corresponding position under its own gravity.

[0039] Because the horizontal material handling arm 30 causes the eyebrow trimmer blade to shift position during material handling, and after a second drop, its position becomes even more difficult to maintain. Therefore, when the partition plate 210 moves downward, it will compress the air supply component. In the initial stage, that is, during the process of the partition plate 210 moving from the highest point of the top groove 240 to its middle position, the air supply component remains connected to the inner ends of the side plates 220 on both sides. The gas generated by the compression will be discharged outward along the longitudinal guide groove 221 opened on the side of the side plate 220 and blown towards the inner end of the straightening groove 212, thus preventing the fallen blade from falling out. The eyebrow trimmer blade inside the correction groove 212 is blown away, causing it to move away from the side plate 220 and adhere to the side of the correction groove 212 away from the side plate 220. At this time, the side of the eyebrow trimmer blade is adhered to the side of the inner end of the correction groove 212, but the adherence position is still uncertain. In order to further correct the position, the partition plate 210 is moved further down to complete the final stage, that is, the partition plate 210 moves from the middle position of the top groove 240 to its bottom position. The air supply component is still under continuous pressure, but at this time, due to the partition... When plate 210 changes position, the two transverse guide grooves 211 become connected to the air supply component. The gas generated by the extrusion will be discharged outward along the transverse guide grooves 211, and the eyebrow trimming blade in contact with the side of the straightening groove 212 will be blown a second time, causing it to move away from the transverse guide groove 211 along the contact side until the side of the eyebrow trimming blade away from the transverse guide groove 211 contacts the opposite side of the transverse guide groove 211. At this time, the diagonal position of the eyebrow trimming blade is exactly in contact with the diagonal position of the inner end of the straightening groove 212, completing the second straightening work of the eyebrow trimming blade. At this time, the straightened eyebrow trimming blade is inspected at the top of the material straightening plate 20. After the inspection is completed, the longitudinal picking arm 50 picks up the straightened eyebrow trimming blade along the pneumatic slide rail, maintains the straightened state, and transfers the eyebrow trimming blade to the top of the processing plate 40 for the third processing. Since the eyebrow trimming blade is in the position straightening state during the loading state, no position straightening is required after it is transferred to the processing plate 40, reducing the operation process and improving the feeding efficiency.

[0040] In addition, the air supply assembly includes an airbag 230 and exhaust pipes 231 disposed on both sides of the bottom end of the airbag 230. Each corner of the bottom end of the partition plate 210 is equipped with a squeezing rod, and the bottom end of each squeezing rod contacts the top end of the airbag 230. The exhaust pipes 231 are connected to the inner end of the airbag 230. A gas collecting chamber 250 is formed on the inner side of the material straightening plate 20. The top end of the exhaust pipe 231 extends into the inner end of the gas collecting chamber 250 and remains in communication with it. The inner wall of the top groove 240 is close to the upper... On both sides of the square position, there are airbags 230 that are connected to the inner end of the air collection chamber 250. On the side of the side plates 220, there are air inlets 222 that are aligned with the airbags 230. The air inlets 222, the longitudinal guide grooves 221 and the airbags 230 are connected. On both sides of the inner wall of the top groove 240 near the middle position, there are connecting grooves 260 that are connected to the inner end of the air collection chamber 250. On the inner wall of the correction groove 212 near the connecting grooves 260, there is a transverse guide groove 211.

[0041] Depend on Figures 2-3 As shown, in practical use, during the downward movement of the partition plate 210 under pressure, the partition plate 210 compresses the top of the airbag 230 through each extrusion rod, causing the airbag 230 to be compressed downward. The gas accumulated at its inner end will be discharged into the inner end of the gas collection chamber 250 along the exhaust pipe 231. Since the two connecting grooves 260 are not aligned with the port of the transverse guide groove 211 during the process of the partition plate 210 moving from the highest point of the top groove 240 to the middle position, and are blocked by the side of the partition plate 210, the airbags 230 on both sides are connected to the gas collection chamber 250 at this time, that is, the gas discharged from the inner end of the gas collection chamber 250. The air will flow into the inner end of the side plate 220 through the air inlet 222 and be discharged outward along the longitudinal guide groove 221, performing the first blowing position correction on the eyebrow trimmer blade located in the inner end of the correction groove 212 until the partition plate 210 moves to the middle position of the top groove 240. At this time, the port of the connecting groove 260 and the port of the transverse guide groove 211 remain connected. The gas in the inner end of the air collection chamber 250 will flow into the inner end of the transverse guide groove 211 through the connecting groove 260 and be discharged into the inner end of the correction groove 212 through the port of the transverse guide groove 211, performing the second blowing position correction on the eyebrow trimmer blade located in the inner end of the correction groove 212.

[0042] Because the blown eyebrow trimmer blade is prone to flipping, although the position correction is completed, the flipped blade will cause errors in the detection results and affect the next stage of processing. Furthermore, the bottom cross-sectional dimensions of the transverse material-taking arm 30 are consistent with the top cross-sectional dimensions of the partition plate 210. After the bottom end of the transverse material-taking arm 30 contacts the top end of the partition plate 210, it works with the correction groove 212 to form a sealed chamber for accommodating the eyebrow trimmer blade, thus limiting the movement of the eyebrow trimmer blade in the blown state. The height of the sealed chamber is less than the height of the eyebrow trimmer blade in the upright state. Figure 6As shown, in actual use, during the position correction process of the eyebrow trimmer blade, the horizontal material handling arm 30 contacts the top of the partition plate 210 and cooperates with the correction groove 212 to form a sealed chamber for accommodating the eyebrow trimmer blade, which limits the eyebrow trimmer blade and prevents it from escaping from the inner end of the correction groove 212. At the same time, the height of the sealed chamber is less than the height of the eyebrow trimmer blade in the vertical state, that is, the eyebrow trimmer blade will not be able to complete the flipping in the sealed chamber, maintaining its initial transfer state for position correction.

[0043] Because the airflow discharged from the inner ends of the transverse guide groove 211 and the longitudinal guide groove 221 has a large dispersion, when the two ends of the longitudinal guide groove 221 and the transverse guide groove 211 are horizontally set, and the contact surface of the eyebrow trimmer blade itself is relatively thin, a large amount of airflow will flow along the top of the eyebrow trimmer blade, forming a negative pressure state above it, which hinders the further movement of the eyebrow trimmer blade and affects the position correction efficiency of the eyebrow trimmer blade. Furthermore, the cross-sections of the transverse guide groove 211 and the longitudinal guide groove 221 are both inclined structures, and the height of the end of the transverse guide groove 211 and the longitudinal guide groove 221 near the correction groove 212 is lower than the height of the other end. In specific use, by Figure 2 as well as Figure 5 As shown, the horizontal guide groove 211 and the vertical guide groove 221 are designed as inclined structures, so that the two sides of the horizontal guide groove 211 and the vertical guide groove 221 form a height difference, generating an airflow that flows from top to bottom and is discharged into the inner end of the correction groove 212, which greatly increases the contact area between the airflow and the eyebrow trimmer blade, improves the airflow utilization rate, and speeds up the eyebrow trimmer blade position correction speed.

[0044] Specifically, the inner end of the side plate 220 is provided with a cavity that communicates with the longitudinal guide groove 221 and the air inlet 222. An inner block 223 is slidably arranged in the inner end of the cavity. Buffer components are provided on both sides of the top of the inner block 223. The force applied by the buffer components overcomes the weight of the inner block 223 and keeps the inner block 223 suspended in the middle position of the inner end of the cavity. The side position of the inner block 223 covers the longitudinal guide groove 221 located at the inner end port of the cavity.

[0045] In practical use, by Figure 5As shown, during the first position correction of the eyebrow trimmer blade, the airflow discharged through the longitudinal guide groove 221 will first be discharged from the side closest to the air inlet 222, resulting in different airflow rates at different positions of the eyebrow trimmer blade. This can easily cause uneven blowing of the eyebrow trimmer blade, affecting its correction effect. However, by using the inner block 223 to pre-cover and seal the port of the longitudinal guide groove 221 located at the inner end of the cavity, the incoming airflow fills the area formed by the cavity and the top of the inner block 223, and the airflow flows in at different rates to apply pressure to the inner block 223. The pressure will continue to increase until it overcomes the force applied by the buffer component, causing the top of the inner block 223 to slide downwards under uniform force and expose the port of the longitudinal guide groove 221 located at the inner end of the cavity. At this time, because the airflow at the inner end of the cavity is restricted by the buffer component, the airflow in each area at the inner end of the air is consistent, that is, the airflow discharged from different areas at the inner end of the longitudinal guide groove 221 is consistent, so that the airflow on the opposite side of the eyebrow trimmer blade is the same, thereby improving the stability during the correction process, avoiding secondary position deviation caused by uneven force, and improving the correction effect.

[0046] In addition, the buffer assembly includes an outer rod 224 and a limiting spring 225 sleeved on the outside of the outer rod 224. A pair of collars are provided at the top of the side plate 220. The two outer rods 224 respectively pass through the cavity and extend into the inner side of the collar at the corresponding position, and the limiting spring 225 is located inside the collar.

[0047] In practical use, by Figure 5 As shown, during the process of the inner block 223 being compressed by the airflow, the inner block 223 will slide downward along the inner end of the cavity, and simultaneously drive the two outer rods 224 to slide along the inner end of the corresponding collar, while compressing the limiting spring 225 sleeved on the outside until the compression limit of the limiting spring 225 is reached. At this time, the outer rods 224 and the inner block 223 can no longer move downward, so that the airflow discharged from each position of the inner end of the longitudinal guide groove 221 is uniform and constant. At the same time, after completing one correction operation, since the air collection chamber 250 and the connecting groove 2 are now connected, the airflow is not completely compressed. The three—60, the transverse guide groove 211, and the air inlet 222—remain in a state of communication. Although the air inlet 222 is still in communication with the inner end of the air collection chamber 250, there is an inner block 223 under stress at the inner end of the side plate 220. At this time, most of the airflow at the inner end of the air collection chamber 250 will be transported to the inner end of the transverse guide groove 211 along the connecting groove 260, ensuring the smooth progress of the second correction work. At the same time, a small amount of airflow discharged from the longitudinal guide groove 221 will still limit the eyebrow trimmer blade in the second correction process, further improving the second correction effect and the overall correction effect.

[0048] The second objective of this invention is to provide a blade storage assembly for use with a blade feeding device in an eyebrow trimming blade assembly line. The assembly includes a storage platform 60 and a guide plate 610 mounted on the top side of the storage platform 60. A picking block 10 is mounted on the bottom side of the guide plate 610, and a slide rail connects the bottom of the picking block 10 to the bottom of the storage platform 60. Both ends of the guide plate 610 have storage slots 611 for stacking eyebrow trimming blades. Two suction heads 110 are positioned opposite the two storage slots 611, and the cross-sectional dimensions of the suction heads 110 are consistent with those of the storage slots 611. A picking assembly is located near the bottom of the storage slot 611. After the suction head 110 moves to the corresponding position inside the storage slot 611, it works in conjunction with the picking assembly and the air suction assembly built into the suction head 110 to pick up a single eyebrow trimming blade.

[0049] The material handling assembly includes a limiting block 620. The side of the limiting block 620 is aligned with the opposite side of the adsorption head 110, and the limiting block 620 is in a plug-in fit with the inner end of the storage tank 611. A reset spring is connected to the plug-in position.

[0050] In practical use, by Figures 8-9 As shown, during the eyebrow trimming blade picking process, firstly, each eyebrow trimming blade is stacked in the same direction inside the two storage slots 611, with the lowest eyebrow trimming blade positioned at the top of the limiting block 620. At this time, the picking block 10 moves along the slide rail towards the storage platform 60, while the two suction heads 110 are respectively facing the two storage slots 611. When the suction head 110 follows the picking block 10 and extends into the corresponding position of the guide plate 610, its end will contact the end of the limiting block 620 in advance and apply a pushing force to it, causing the limiting block 620 to extend into the inner end of the guide plate 610 and squeeze the reset spring connected to it. At this time, the eyebrow trimming blade located at the top of the limiting block 620 will slide down to the top of the suction head 110 and detach from the inside of the storage slot 611. The air suction component built into the suction head 110 is activated to suction the eyebrow trimming blade. At this time, the picking block 10 slides in the opposite direction along the slide rail and carries out the detached eyebrow trimming blade through the suction head 110.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
