[0038] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0039] like Figures 1 to 9 As shown in , the needle loading device provided in this embodiment includes a workbench 100, a carrier 400 and an adjustment mechanism 500. A feeding mechanism 200 is provided on the upper surface of the workbench 100, and a transfer mechanism 300 is provided on one side of the feeding mechanism 200. A needle loading space 110 is provided on the upper surface of the workbench 100. There are multiple carriers 400, and multiple carriers 400 are distributed in the needle loading space 110 along a first direction. Each carrier 400 is provided with multiple rows of needle holes 411 at intervals along a direction perpendicular to the first direction. The adjustment mechanism 500 includes multiple pushing components, and the multiple pushing components are transmission-connected to the multiple carriers 400, and the pushing direction of the pushing components is at an angle to the first direction.

[0040] Specifically, in this embodiment, the carrier 400 is sent into the upper needle space 110 from one side of the upper needle space 110, and the moving direction of the carrier 400 during the sending process is the first direction. The length direction of the feeding mechanism 200 in this embodiment is the same as the first direction, and multiple carriers 400 are adjacently arranged in the upper needle space 110 along the first direction, and the needle 700 is stored in the feeding mechanism 200.

[0041] When placing needles, the transfer mechanism 300 moves to the feeding mechanism 200, takes out the needles 700 and transfers them to the carrier 400, and the adjustment mechanism 500 pushes the carrier 400 in a direction away from the needle placing space 110, so that the needle holes 411 in different rows on different carriers 400 are located at the needle receiving position, and the transfer mechanism 300 can place the carried needles 700 into the needle placing holes 411. Specifically, the needle placing process is as follows: the carrier 400 is placed into the needle placing space 110 from one side of the workbench 100, and this position is the first position. When placing needles, the adjustment mechanism 500 pushes multiple carriers 400 in the needle placing space 110, and the carrier 400 at the first position is pushed by the pushing assembly corresponding to the first position, so that the first discharge needle hole 411 is located at the first needle placing position, that is, the first needle placing position. After the carrier 400 reaches the first needle placing position, the transfer mechanism 300 places the needle into the first discharge needle hole 411, which is the first needle placing.

[0042] After the first needle placement, the pushing component pushes the carrier 400 back to the upper needle space 110. The carrier 400 is pushed by the newly inserted carrier 400 to move toward the other side of the workbench 100 to the second position for a second needle placement. During the second needle placement, the newly inserted carrier 400 performs needle placement at the first position according to the above-mentioned operation. At the same time, the pushing component corresponding to the second position pushes the carrier 400 located at the second position again, so that the second discharge needle hole 411 is located at the needle placement position. After the carrier 400 reaches the second needle placement position, the rotating mechanism places the needle into the second discharge needle hole 411. After the second needle placement, the pushing component pushes the carrier 400 back to the second position again. During this process, the carrier 400 located at the first position is pushed to the first needle placement position for a first needle placement.

[0043] As another new carrier 400 is pushed into the needle loading space 110, the multiple carriers 400 located in the needle loading space 110 move again in the direction away from the first position, reach the next position and place needles again. At the same time, the carriers 400 located at the first position and the second position place needles according to the above-mentioned operations, and the subsequent carriers 400 pushed into the needle loading space 110 are operated in this way, until all the needle placing holes 411 in the carriers 400 are filled, and the fully loaded carriers 400 are sent out of the needle loading space 110 under the push of subsequent carriers 400.

[0044] Furthermore, in this embodiment, three carriers 400 can be sequentially placed in the needle loading space 110, and the three carriers are adjacently arranged along the first direction, and a pushing assembly is arranged on both sides of each carrier 400. The pushing assembly on one side is used to push the carrier 400 to the needle placement position, and the pushing assembly on the other side is used to push the carrier 400 from the needle placement position back to the needle loading space 110 after the needle is placed, that is, to reset the carrier 400.

[0045] It can be seen from the above-mentioned needle-loading process that the needle-loading device provided in this embodiment can move the carrier 400 through the adjustment mechanism 500, change the position of the carrier 400 to cooperate in needle placement, thereby realizing the sequential placement of multiple rows of needle holes 411 of multiple carriers 400, and then realizing the needle loading of multiple rows of needles 700 of multiple carriers 400 together, and the needle loading is fully automated without the need for human intervention, with low operating difficulty, improved processing efficiency and high yield rate.

[0046] Among them, in this embodiment, in order to ensure the moving direction and removal direction of the carrier 400, a guide groove is provided at the edge of the workbench 100, and the guide groove extends along the first direction, and the notch of the guide groove faces the needle loading space 110, thereby ensuring that the carrier newly placed on the workbench 100 can accurately enter the needle loading space 110 for needle loading.

[0047] In this embodiment, along the second direction perpendicular to the first direction, a push assembly is provided on both sides of the upper needle space 110. The push assembly includes a linear drive member and a push plate, the linear drive member is provided along the second direction, the push plate is located between the upper needle space 110 and the linear drive member, and is connected to the driving end of the linear drive member.

[0048] Specifically, the linear driving member in this embodiment can control the driving end to move back and forth along the second direction, and the pushing plate located on one side of the needle upper space 110 performs the same action under the push of the driving end on this side, thereby pushing the carrier 400 to the needle placement position. After the needle placement is completed, the pushing plate located on the other side pushes the carrier 400 under the push of the driving end on the same side, thereby pushing the carrier 400 to its original position, so that a new empty carrier 400 enters the needle upper space 110 and pushes other carriers 400 in the needle upper space 110 to move in sequence.

[0049] It should be noted that the linear drive member can be any setting that can meet the linear drive, such as a cylinder, a spring with a guide member or a lead screw. The linear drive member in this embodiment is a cylinder, and the push plate is connected to the output end of the cylinder. Similarly, the push components on both sides can share a driving source, for example, they are arranged in sequence as a reset push plate, a carrier 400, an upper needle push plate, and a cylinder. The two push plates are fixedly connected by a support rod, and the two push plates are driven and connected to the extension rod of the cylinder. When the extension rod of the cylinder extends in the first direction, the upper needle push plate pushes the carrier 400 to the upper needle space 110. When the extension rod of the cylinder retracts, the reset push plate pushes the carrier 400 back to its original position.

[0050] Furthermore, the second direction is the moving direction of the output end of the linear drive member, and in this embodiment, the second direction is perpendicular to the first direction. When the transfer mechanism 300 places needles, the multiple carriers 400 are arranged in a staggered manner under the push of the multiple push components in the upper needle space 110, and the needle holes 411 to be placed on each carrier 400 are located in the same row, that is, the first discharge needle hole 411 of the carrier 400 at the first position, the second discharge needle hole 411 of the carrier 400 at the second position, and the third discharge needle hole 411 of the carrier 400 at the third position are located on the same straight line, and the transfer mechanism 300 can place needles on the needle holes 411 located in the same row at one time.

[0051] In this embodiment, the needle loading device further includes a guide mechanism. The guide mechanism includes a guide plate 600, which is disposed above the needle loading space 110. The guide plate 600 is provided with a plurality of guide grooves 610 that are opposite to the positions of the respective needle placing holes 411. The transfer mechanism 300 has a material taking position and a material placing position. The transfer mechanism 300 is provided with a needle taking hole 322. When the transfer mechanism 300 is located at the material placing position, one end of the guide groove 610 is connected to the needle taking hole 322, and the other end is opposite to the needle placing hole 411.

[0052] When the transfer mechanism 300 is at the material taking position, the transfer mechanism 300 is close to the feeding mechanism 200, and the position of the material taking hole is opposite to the position of each needle 700 in the feeding mechanism 200, and then the needle 700 is taken out and stored in the needle taking hole 322. When the transfer mechanism 300 is at the material releasing position, the guide plate 600 is located between the transfer mechanism 300 and the needle releasing hole 411, and the needle 700 in the needle taking hole 322 falls into the guide groove 610. The guide mechanism can guide the falling needle 700, and the needle slides along the guide groove 610 and falls into the needle releasing hole 411 opposite to it.

[0053] In this embodiment, the guide groove 610 is provided on the side of the guide plate 600, and the guide mechanism further includes an auxiliary plate 620 and an auxiliary driving member. The auxiliary plate 620 is provided on the side of the guide plate 600 where the guide groove 610 is provided, and a side wall of the auxiliary plate 620 opposite to the guide groove 610 is provided with a plurality of auxiliary grooves corresponding to the positions of the plurality of guide grooves 610 one by one. The auxiliary driving member is in transmission connection with the auxiliary plate 620, and the driving direction of the auxiliary driving member is perpendicular to the side wall of the guide plate 600 where the guide groove 610 is provided.

[0054] Among them, the auxiliary driving component can adopt a mechanical device such as a cylinder, a hydraulic cylinder, etc. that can perform reciprocating motion. Specifically, the auxiliary driving component in this embodiment is a cylinder, and the output end of the cylinder is connected to the auxiliary plate 620. The moving direction of the output end of the cylinder is perpendicular to the side wall of the guide plate 600, thereby realizing the movement of the auxiliary plate 620.

[0055] The auxiliary plate 620 is transmission-connected to the auxiliary driving member, and the driving direction of the auxiliary driving member is perpendicular to the side wall of the guide groove 610 set on the guide plate 600. When placing the needle, the auxiliary driving member operates to drive the auxiliary plate 620 to move toward the direction close to the guide plate 600. The auxiliary groove on the auxiliary guide plate 600 can be merged with the guide groove 610 in a one-to-one correspondence to form a through groove with upper and lower openings. The needle 700 falls into the through groove and falls into the needle placement hole 411 after passing through the through groove. The auxiliary guide plate 600 can provide an auxiliary groove to be merged with the guide groove 610, thereby closing the side of the guide groove 610 to prevent the needle 700 from falling out of the guide groove 610 during the falling process.

[0056] In this embodiment, a needle placement groove 410 is provided on the carrier 400, and a needle placement hole 411 is provided on the bottom wall of the needle placement groove 410. A plurality of positioning plates 630 are provided at the bottom of the guide plate 600. One end of the positioning plate 630 is opposite to the needle placement groove 410, and the plurality of positioning plates 630 are provided in a one-to-one correspondence with the plurality of needle placement grooves 410.

[0057] The positioning plate 630 is opposite to the needle placement groove 410 to facilitate determining the position of the guide plate 600 during the needle placement action, ensuring that the guide groove 610 on the positioning plate 630 is opposite to the needle placement hole 411, and the needle 700 can enter the needle placement hole 411 after sliding out of the guide groove 610.

[0058] In this embodiment, the positioning plate 630 is provided with an extension groove which vertically penetrates the positioning plate 630 . The extension groove is connected with the guide groove 610 and the pinhole 411 .

[0059] Each positioning plate 630 is provided with a plurality of extension grooves, and specifically, the number of the extension grooves on each positioning plate 630 is the same as the number of the needle holes 411 in a row. The extension grooves can guide the needles 700 falling from the guide grooves 610 again, so as to prevent the needles 700 from deviating and failing to smoothly fall into the needle holes 411.

[0060] In this embodiment, the needle loading device further includes a material ejection mechanism, which includes a lifting drive member and a lifting part, wherein the lifting parts are provided in plurality and are arranged corresponding to the plurality of carriers 400, and the driving end member of the lifting drive member moves in a vertical direction and is connected to the lifting part.

[0061] The lifting drive member may be a mechanical device capable of reciprocating motion, such as a cylinder or a hydraulic cylinder. Specifically, the lifting drive member in this embodiment is a cylinder.

[0062] The lifting drive can drive the lifting part to move in the vertical direction. Specifically, the lifting part in this embodiment is a flat plate structure, the bottom surface of the lifting part is connected to the output end of the cylinder, the moving direction of the output end of the cylinder is the vertical direction, and the top surface of the lifting part is in contact with the bottom surface of the carrier 400.

[0063] When placing the needle, the lifting part can lift the carrier 400 and move the carrier 400 upward. After the carrier 400 rises, the positioning plate 630 extends into the needle placement groove 410. At this time, the bottom notch of each extension groove is connected with the corresponding needle placement hole 411, further improving the accuracy of needle placement. After the needle is placed, the lifting part is reset, the carrier 400 falls back to its original position, and the positioning plate 630 escapes from the needle placement groove 410 and moves with the subsequent push of the carrier 400. Under the lifting and falling action of the lifting mechanism, the carrier 400 is lifted when the needle is placed, and can cooperate with the positioning plate 630 to improve the accuracy of needle placement. After the needle is placed, it falls back to facilitate the subsequent push of the carrier 400. The carrier 400 will not be unable to move due to the presence of the positioning plate 630.

[0064] Among them, a positioning block 640 is provided at the bottom of the guide plate 600, and a positioning groove 420 adapted thereto is provided at the top of the carrier 400. When the carrier 400 moves to the bottom of the guide plate 600, the positions of the positioning block 640 and the positioning groove 420 are relative. Moreover, after the carrier 400 is lifted up by the lifting part, the positioning block 640 is inserted into the positioning groove 420, thereby realizing the determination of the relative position of the guide plate 600 and the carrier 400, and ensuring that the position of the carrier 400 is the preset position when the needle is dropped, and the guide groove 610, the extension groove and the needle hole 411 are connected, thereby improving the accuracy of needle drop.

[0065] In this embodiment, the feeding mechanism 200 includes a mounting frame 210, a needle storage slot 220 and a material ejection assembly 230. The mounting frame 210 is disposed on the workbench 100. The needle storage slot 220 is disposed on the workbench 100, and a material ejection hole is disposed at the bottom of the needle storage slot 220. The material ejection assembly 230 includes a material ejection member 231, which is disposed in the material ejection hole and slidably cooperates with the material ejection hole.

[0066] The mounting frame 210 is set up on the workbench 100, and is used to support structures such as the needle storage slot 220. Specifically, the length direction of the mounting frame 210 in this embodiment is the same as the first direction, and the needle storage slots 220 are arranged at intervals on the top of the mounting frame 210 along the length direction of the mounting frame 210. The ejector 231 can slide up and down along the ejector hole, so as to eject the needle 700 in the needle storage slot 220 to the outside of the needle storage slot 220.

[0067] Among them, see Figure 6 The ejector 231 in this embodiment is an ejector plate, which is arranged in the vertical direction, and a groove is provided on the top of the ejector plate, the extension direction of the groove extends along the length direction of the upper edge of the ejector plate, and the contour of the groove matches the outer contour of the needle 700. When the ejector plate is ejected upward from the ejector hole, the needle 700 is inserted into the groove and is lifted up by the ejector plate to the top of the needle storage slot 220, so that the transfer mechanism 300 can take the needle 700 and feed the transfer mechanism 300.

[0068] In addition, a movable plate 232 is provided at the bottom of the ejection plate in this embodiment, and a power element is connected below the movable plate 232. The power element can push the movable plate 232 to move in the vertical direction to realize the ejection action of the ejection plate.

[0069] It should be noted that the power element may be a device that can perform regular linear reciprocating motion, such as a cylinder or a hydraulic cylinder. The power element in this embodiment is a cylinder.

[0070] In this embodiment, there are a plurality of ejecting holes. A partition plate 221 is disposed in the needle storage slot 220, and the partition plate 221 is disposed between two adjacent ejecting holes.

[0071] Specifically, two, three or four ejection holes can be provided. In the present embodiment, there are three ejection holes, which are arranged at intervals in the needle storage slot 220. A partition plate 221 is provided between two adjacent ejection holes. The partition plate 221 is provided in the vertical direction to separate the ejection holes and two adjacent ejection plates, so as to prevent the ejection plates in multiple ejection holes from being ejected together and the needles 700 on each ejection plate from colliding and affecting each other.

[0072] In this embodiment, an auxiliary blanking piece is disposed on the guide plate 600 .

[0073] Specifically, the auxiliary blanking part in this embodiment is a vibration element. After the transfer device transfers the needle 700 to the guide groove 610, the needle 700 may be retained on the groove wall. The vibration element generates vibration after operation, causing the guide plate 600 to vibrate, thereby causing the needle 700 to fall off the groove wall of the guide groove 610 and smoothly slide into the needle release hole 411.

[0074] The vibration element in this embodiment is a pneumatic vibrator.

[0075] In this embodiment, the transfer mechanism 300 includes a moving component and a negative pressure component. The moving component is provided with a plurality of needle holes 322, the number of the needle holes 322 is the same as the material ejection holes and the spacing between the holes is the same, and the negative pressure component is connected to the needle holes 322. When the moving component is in the material taking position, the needle holes 322 are opposite to the material ejection holes, and when the moving component is in the material discharging position, the material ejection member 231 is lifted up, and the needle holes 322 are opposite to the material ejection member 231.

[0076] Specifically, the ejector 231 in this embodiment is an ejector plate, and a groove body capable of accommodating a single needle 700 is provided on the top of the ejector plate. When the ejector plate is lifted up, the needle 700 slides into the groove body and moves up with the ejector plate. Each needle-removing hole 322 is connected to a negative pressure generating assembly. When the needle 700 is removed, the moving assembly is located at the material removal position, and the ejector plate ejects the needle 700 to the top of the needle storage slot 220. At this time, the positions of multiple needles 700 and multiple needle-removing holes 322 correspond one by one. The negative pressure generator generates negative pressure to generate suction in the needle-removing holes 322, and sucks the corresponding needles 700 onto the needle-removing holes 322, thereby realizing negative pressure needle removal 700, so that the needle 700 is fixed on the needle-removing hole 322 and moves with the moving assembly.

[0077] In this embodiment, the moving assembly includes a rotating arm 310 and a material storage plate 320. One end of the rotating arm 310 is rotatably connected to the mounting frame 210. The material storage plate 320 is disposed at the other end of the rotating arm 310, and a plurality of needle suction grooves 321 are disposed on the material storage plate 320. The needle removal hole 322 is disposed in the needle suction groove 321.

[0078] Specifically, see Figure 4 In this embodiment, there are two rotating arms 310, and the ends of the two rotating arms 310 are respectively rotatably connected to the two ends of the bottom of the mounting frame 210, thereby forming a rotating structure. The material storage plate 320 is arranged at one end of the rotating arm 310 away from the bottom of the mounting frame 210, and both ends of the material storage plate 320 are integrally connected to the rotating arm 310. A plurality of needle suction grooves 321 are arranged at intervals along the length direction of the material storage plate 320, and each needle suction groove 321 is provided with a needle removal hole 322. Please refer to Figure 8 When the needle 700 is removed, the needle removal hole 322 generates suction to suck the needle 700 into the needle suction groove 321 , thereby realizing the needle removal action 700 and storing the needle 700 in the needle suction groove 321 .

[0079] When placing the needle, the needle-taking hole 322 absorbs the needle into the needle-absorbing groove 321, and the rotating arm 310 rotates to move the material storage plate 320 to the top of the guide plate 600, and the bottom surface of the material storage plate 320 abuts against the top surface of the guide plate 600. At this time, the transfer mechanism 300 reaches the material-putting position, the bottom notch of the needle-absorbing groove 321 is connected with the top notch of the guide groove 610, the negative pressure generator stops running, the needle-taking hole 322 loses suction, and the needle 700 falls freely along the needle-absorbing groove 321 under the action of gravity and falls into the guide groove 610. Under the action of gravity, the needle 700 passes through the extension groove of the guide groove 610 in turn and falls into the needle-putting hole 411, thereby completing the needle-taking and needle-putting actions.
