Description

Technical Field

[0001] This utility model relates to the field of PIN needle feeding technology, and in particular to a needle feeding device and system. Background Technology

[0002] Ceramic light sources are a type of light source that uses ceramic materials as a base or key component, including ceramic substrates, LED chips, and packaging materials. Ceramic light sources primarily use ceramic substrates as the support material and are manufactured using surface mount technology. To achieve conductive connections between different electronic components, such as the conductive connection between the thick-film circuitry of the LED chip and the power supply, pins are used as the conductive material. Pins are typically made using a copper-nickel plating process, which provides good conductivity. However, PINs arrive in bulk in bags and require initial sorting.

[0003] Generally, existing PIN needle feeding processes mainly employ linear vibration, specifically using a linear vibrator to push the PIN needles forward from the storage track. However, this linear vibration method often suffers from insufficient stability during continuous production. Furthermore, the 1.0mm diameter PIN needles are prone to bending, and even slight bending can cause them to become stuck in the storage track or feeding mechanism, resulting in jamming and hindering further forward movement. In addition, prolonged linear vibration often leads to loosening of screws within the feeding mechanism, increasing the failure rate. Simultaneously, during the feeding process, the vibration and friction between the PIN needles and the metal storage track, as well as the misalignment and compression with the feeding mechanism, can damage the surface plating of the PIN needles, thereby affecting their conductivity.

[0004] Therefore, the existing PIN pin distribution method has drawbacks such as high failure rate of material jamming, poor stability and easy damage to PIN pins. Utility Model Content

[0084] To address the problems mentioned above, this utility model provides a needle material separating device and system for separating vertically stacked needle materials. It aims to solve the technical problems of high jamming failure rate, poor stability, and easy damage to the needle materials in existing needle material separating methods, effectively reducing the failure rate. Furthermore, the needle material separating device and system of this utility model mainly relies on gravity to allow the needle materials to fall freely, which can greatly reduce damage to the coating on the needle material surface. To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0085] like Figure 1 As shown, this utility model provides a needle material separating device 100 for separating vertically stacked needle materials 200.

[0086] In the production process of ceramic light sources, pins are mainly used as conductive connectors. Generally, such as... Figure 2 As shown, the needle material 200 includes a needle cap portion 210 and a needle shank portion 220. The needle cap portion 210 has a thickness of 0.4 mm and a diameter of 2.2 mm; the needle shank portion 220 has a diameter of 1.0 mm. Multiple needle materials 200 are stacked vertically together, with the needle shank portion 210 of the upper needle material aligned and abutting against the needle cap portion 220 of the lower needle material.

[0087] like Figure 1 As shown, the needle material dispensing device 100 includes: a needle plate 110, a first stop 120, a first drive 130, a second stop 140, and a second drive 150.

[0088] Specifically, such as Figure 2 As shown, the needle plate 110 is provided with a vertical first needle tube 111. The diameter of the first needle tube 111 is adapted to the needle material 200 and aligned with the vertically stacked needle material 200. The needle plate 110 is provided with a first needle outlet 112 and a second needle outlet 113 from top to bottom, which are connected to the first needle tube 111.

[0089] In one embodiment, such as Figure 4 as well as Figure 5 As shown, the material distribution plate 110 includes: a first material distribution block 114, a second material distribution block 115, and a third material distribution block 116. In this embodiment, the material distribution plate 110 is disassembled into three parts, which makes it easier to process. Furthermore, if the first needle tube 111 becomes clogged or jammed, it can be quickly disassembled and maintained, resulting in lower maintenance costs.

[0090] like Figure 4 as well as Figure 5 As shown, the first material distribution block 114 has a vertical first tube fixing hole 114a; the second material distribution block 115 is fixedly connected to the first material distribution block 114, and the second material distribution block 115 has a vertical second tube fixing hole 115a and a second needle tube 115b; the third material distribution block 116 is fixedly connected to the second material distribution block 115; the third material distribution block 116 has a vertical third needle tube 116a and a third tube fixing hole 116b, the upper surface has a groove adapted to the first stop member 120 as a first needle port 112, and the side has a square hole adapted to the second stop member 140 as a second needle port 113. Figure 4 As shown, the first needle port 112 and the second needle port 113 are respectively connected to the third needle tube 116a.

[0091] It should be noted that the first tube fixing hole 114a, the second tube fixing hole 115a, the second needle tube 115b, the third needle tube 116a, and the third tube fixing hole 116b are interconnected and coaxially arranged to form the first needle tube 111, which is adapted to the needle material 200 and allows the needle material 200 to pass through and be distributed.

[0092] In one specific embodiment, the diameters of the first tube fixing hole 114a and the second tube fixing hole 115a are 4 mm; the diameters of the second needle tube 115b and the third needle tube 116a are 2.5 mm; and the diameter of the third tube fixing hole 116b is 6 mm.

[0093] In a preferred embodiment, such as Figure 5 As shown, the first material distribution block 114, the second material distribution block 115 and the third material distribution block 116 are respectively provided with threaded holes. The first material distribution block 114 and the second material distribution block 115 are fixedly connected by screws, and the second material distribution block 115 and the third material distribution block 116 are fixedly connected by screws.

[0094] And, as Figure 5 As shown, the lower surface of the first material distribution block 114 is provided with a limiting groove 114b, and the upper surface of the second material distribution block 115 is provided with a protrusion 115c adapted to the limiting groove 114b. The limiting groove 114b and the protrusion 115c are fitted together to better fix the first material distribution block 114 and the second material distribution block 115. Specifically, the limiting groove 114b has a depth of 2mm and a width of 5mm; the protrusion 115c has a height of 2mm and a width of 8mm.

[0095] In one embodiment, such as Figure 5As shown, the outer sides of the first material distribution block 11, the second material distribution block 115, and the third material distribution block 116 are respectively provided with interconnected through grooves. The through grooves extend through the first needle tube 111 (i.e., through the first tube fixing hole 114a, the second tube fixing hole 115a, the second needle tube 115b, the third needle tube 116a, and the third tube fixing hole 116b), and their width is smaller than the diameter of the needle rod portion 220 of the needle material 200, preferably 0.5mm, so as to facilitate observation of whether a needle blockage or jamming fault occurs in the first needle tube 111.

[0096] In one embodiment, the first stop 120 is adapted to the first needle port 112 provided on the needle plate 110, and is used to insert into the first needle port 112 to perform a telescopic movement under the drive of the first drive member 130, thereby restricting or allowing the needle material 200 to pass through the first needle port 112. Specifically, the depth of the first needle port 112 is 0.5 mm and the width is 10 mm; the thickness of the first stop 120 is 0.5 mm.

[0097] It should be noted that the first stop 120 does not exit the first needle port 112 when it extends or retracts, and the first needle port 112 can restrict the degree of freedom of movement of the first stop 120.

[0098] like Figure 6 As shown, the first stop 120 includes: a first T-shaped connecting hole 121, a U-shaped needle hole 122, and a first limiting step 123. The first T-shaped connecting hole 121 and the U-shaped needle hole 122 are respectively disposed on the left and right sides of the first stop, and the first limiting step 123 is disposed on the inner and outer sides of the first stop 120.

[0099] The U-shaped needle hole 122 includes an arc portion and parallel edges. The arc portion is a semicircle, and in one specific embodiment, the diameter of the arc portion is 2.8 mm. If the center of the arc of the U-shaped needle hole 122, i.e., the center of the arc portion, is aligned with the first needle tube 111, since the diameter of the arc portion is larger than the diameter of the needle cap portion 210 and the needle bar portion 220 of the needle material 200, the needle material 200 can completely pass through the U-shaped needle hole 122, thereby passing through the first needle outlet 112 and falling freely into the lower section of the first needle tube 111, i.e., into the third needle tube 116a. If the center of the arc of the U-shaped needle hole 122, i.e., the center of the arc portion, extends beyond the first needle tube 111, the arc edge of the U-shaped needle hole 122 exceeds the edge of the first needle tube 111, partially obscuring the first needle tube 111 to limit the needle material 200.

[0100] The first limiting step 123 is used to restrict the first stop 120 from extending to a designated position. Specifically, the width of the first stop 120 on the side of the U-shaped needle hole 122 is the same as or slightly smaller than the width of the first needle port 112, allowing the first stop 120 to be inserted into the first needle port 112; however, the width of the first stop 120 on the side of the first T-shaped connecting hole 121 is greater than the first needle port 112. When the step surface of the first limiting step 123 abuts against the side of the third material distribution block 116, it restricts the first stop 120 from continuing to be inserted into the first needle port 112, thereby restricting the first stop 120 from extending to the designated position.

[0101] In detail, when the first stop 120 extends to the designated position, the arc center of the U-shaped needle hole 122 extends out of the first needle tube 111, the side edge of the U-shaped needle hole 122 abuts against the needle bar portion 220 of the needle material 220, and the upper surface of the first stop 120 abuts against the needle cap portion 210, thereby supporting the needle cap portion 210, preventing the needle material 200 from falling freely, and also preventing damage to the surface coating of the needle bar portion 220.

[0102] In one embodiment, the first driving member 130 is connected to the first stop member 120, and is used to drive the first stop member 120 to insert into the first needle port 112 to perform a telescopic action.

[0103] When the first driving member 130 extends the first stop member 120, the first stop member 120 approaches the first needle tube 111 and partially blocks the first needle tube 111, allowing the needle bar portion 220 of the needle material 200 to pass through the first stop member 120, but the needle cap portion 210 is limited. In a specific embodiment, when the first driving member 130 extends the first stop member 120, the arc center of the U-shaped needle hole 122 extends out of the first needle tube 111, allowing the needle bar portion 220 of the needle material 200 to pass through the U-shaped needle hole 122, but the needle cap portion 210 is limited, thereby supporting the needle material 200.

[0104] When the first driving member 130 retracts the first stop member 120, the first stop member 120 moves away from the first needle tube 111, causing the needle bar portion 220 and needle cap portion 210 of the needle material 200 to pass through the first needle outlet 112. This allows the needle material 200 to fall freely into the lower section of the first needle tube 110 due to gravity, i.e., into the third needle tube 116a. In a specific embodiment, when the first driving member 130 retracts the first stop member 120, the arc center of the U-shaped needle hole 122 aligns with the first needle tube 111, causing the needle bar portion 220 and needle cap portion 210 of the needle material 200 to pass through the U-shaped needle hole 122.

[0105] In one embodiment, such as Figure 3 as well as Figure 4 As shown, the first driving member 130 includes a first piston rod 131. A first connecting member 132 is mounted on the first piston rod 131, and the first connecting member 132 is locked by a first locking member 133. It should be noted that the first connecting member 132 is adapted to the first T-shaped connecting hole 121 of the first stop member 120. By embedding the first connecting member 132 into the first T-shaped connecting hole 121, the first piston rod 131 is connected to the first stop member 120, thereby enabling the first driving member 130 to drive the first stop member 120 to extend and retract within the first needle port 112. Preferably, the first connecting member 132 is an internal hexagon screw, installed on the first piston rod 131, and embedded in the first T-shaped connecting hole 121, used to drive the first stop member 120 to extend and retract. The first locking member 133 is a nut adapted to the internal hexagon screw, serving as an anti-loosening measure. The retraction position of the first stop 120 can be adjusted by adjusting the screwing depth of the internal hex screw.

[0106] like Figure 3 as well as Figure 4 As shown, the first driving member 130 further includes a fourth sensor 134. The fourth sensor 134 is used to sense the extension and retraction position of the first piston rod 131, thereby confirming that the first piston rod 131 can drive the first stop member 120 to retract to a designated position. When the first piston rod 131 drives the first stop member 120 to retract to the designated position, the first stop member 120 moves away from the first needle tube 111. Specifically, the arc center of the U-shaped needle hole 122 is aligned with the first needle tube 111, so that the needle bar portion 220 and the needle cap portion 210 of the needle material 200 pass through the U-shaped needle hole 122, thereby causing the needle material 200 to fall into the third needle tube 116a due to gravity.

[0107] To better secure the first drive component 130, such as Figure 3 as well as Figure 4 As shown, the first driving component 130 further includes a first mounting block 135, used to fix the first driving component 130 to the third material distribution block 116. Specifically, as... Figure 5 As shown, the third material distribution block 116 has a first mounting groove 116c on its side that is adapted to the first mounting block 135. The first mounting block 135 is fixed in the first mounting groove 116c with screws. The first mounting groove 116c has a depth of 1mm and a width of 6mm.

[0108] In one embodiment, the second stop 140 is adapted to the second needle port 113 provided on the needle plate 110, and is used to insert into the second needle port 113 to perform a telescopic action under the drive of the second drive member 150, thereby allowing or restricting the needle material 200 to pass through the second needle port 113. Specifically, the size of the second needle port 113 is 8*8mm, and the thickness of the second stop 140 is also 8mm.

[0109] It should be noted that the second stop 140 does not exit the second needle port 113 when it extends or retracts, and the second needle port 113 can restrict the degree of freedom of movement of the second stop 140.

[0110] In one embodiment, such as Figure 3 , Figure 4 as well as Figure 7 As shown, the second stop includes: a needle through hole 141, an air blowing blind hole 142, and a threaded hole 143.

[0111] Specifically, the through hole 141 extends vertically, and preferably, its diameter is set to 2.6 mm, which is larger than the diameter of the needle cap 210 and the needle shank 220 of the needle material 200, allowing the needle cap 210 and the needle shank 220 to pass through. The air blowing blind hole 142 is provided on the lower surface of the second stop member 140 and is set as a blind hole, such as... Figure 4 As shown. The threaded hole 143 is provided on the side of the second stop 140 and communicates with the air blowing blind hole 142. It can be fixedly connected to the air pipe through the elbow joint 190.

[0112] In one embodiment, such as Figure 7 As shown, the second stop 140 also includes a second T-shaped connecting hole 144 and a second limiting step 145.

[0113] The second limiting step 145 is disposed on the inner and outer sides of the second stop 140 to restrict the second stop 140 from extending to a designated position. Specifically, the width of the second stop 140 on the side of the needle passage 141 is the same as or slightly smaller than the width of the second needle port 113, allowing the second stop 140 to be inserted into the second needle port 113; however, the width of the second stop 140 on the side of the second T-shaped connector 144 is greater than that of the second needle port 113. When the step surface of the second limiting step 145 abuts against the side of the third material distribution block 116, it restricts the second stop 140 from continuing to be inserted into the second needle port 113, thereby restricting the second stop 140 from extending to the designated position.

[0114] In detail, when the second stop 140 extends to the designated position, the needle through hole 141 is aligned with the first needle tube 111, specifically with the third needle tube 116a, so that the needle bar portion 220 and the needle cap portion 210 of the needle material 200 pass through the needle through hole 141.

[0115] In one embodiment, the second drive member 150 is connected to the second stop member 140, and is used to drive the second stop member 140 to insert into the second needle port 113 to perform a telescopic action.

[0116] When the second driving member 150 extends the second stop member 140, the needle passage hole 141 aligns with the first needle passage tube 111, that is, with the third needle passage tube 116a, allowing the needle bar portion 220 and needle cap portion 210 of the needle material 200 to pass through the needle passage hole 141. When the second driving member 150 retracts the second stop member 140, the needle passage hole 141 retracts, causing the needle material 200 to stack vertically on the upper side of the second stop member 140. In a specific embodiment, when the second driving member 150 retracts the second stop member 140, the air blowing blind hole 142 aligns with the third needle passage tube 116a, allowing air to be blown into the air blowing blind hole 142 through the air pipe.

[0117] In one specific embodiment, such as Figure 3 as well as Figure 4As shown, the second driving member 150 includes a second piston rod 151. A second connecting member 152 is mounted on the second piston rod 151 and locked by a second locking member 153. It should be noted that the second connecting member 152 is adapted to the second T-shaped connecting hole 144 of the second stop member 140. By embedding the second connecting member 152 into the second T-shaped connecting hole 144, the second piston rod 151 is connected to the second stop member 140, so that the second piston rod 151 drives the second stop member 140 to insert into the second needle port 113 for extension and retraction. Preferably, the second connecting member 152 is an internal hexagon screw, installed on the second piston rod 151 and embedded in the second T-shaped connecting hole 144, used to drive the second stop member 140 for extension and retraction. The second locking member 153 is a nut adapted to the internal hexagon screw, serving as an anti-loosening measure. The retraction position of the second stop 140 can be adjusted by adjusting the screwing depth of the internal hex screw.

[0118] like Figure 3 as well as Figure 4 As shown, the second drive member 150 further includes a fifth sensor 154. The fifth sensor 154 is used to sense the extension and retraction position of the second piston rod 151, thereby confirming that the second piston rod 151 drives the second stop member 140 to retract to a designated position. When the second piston rod 151 drives the second stop member 140 to retract to the designated position, the air blowing blind hole 142 is aligned with the third needle tube 116a.

[0119] To better secure the second drive component 150, such as Figure 3 as well as Figure 4 As shown, the second driving component 130 further includes a second mounting block 155, used to fix the second driving component 150 to the third material distribution block 116. Specifically, as... Figure 5 As shown, the third material distribution block 116 has a second mounting groove 116d on its side that is adapted to the second mounting block 155. The second mounting block 155 is fixed in the second mounting groove 116d with screws. The second mounting groove 116d has a depth of 1mm and a width of 6mm.

[0120] In one embodiment, such as Figure 1 As shown, the needle material dispensing device 100 further includes a needle storage structure 160 and a needle feeding structure 170.

[0121] like Figure 1As shown, the needle storage structure 160 includes a needle storage tube 161. One end of the needle storage tube 161 is fixedly connected to the vibratory feeder, and the other end is connected to the first tube fixing hole 114a and the second tube fixing hole 115a; the inner diameter of the needle storage tube 161 is adapted to the needle material 200, and the outer diameter is adapted to the diameter of the first tube fixing hole 114a and the second tube fixing hole 115a. In a specific embodiment, as... Figure 4 As shown, the upper end of the second tube fixing hole 115a is provided with a conical chamfer, and the end face of the needle storage tube 161 extends to the lower circular end face of the conical chamfer. Preferably, the outer diameter of the needle storage tube 161 is 4mm; the diameter of the first tube fixing hole 114a is also set to 4mm, used to clamp and fix the needle storage tube 161. The inner diameter of the needle storage tube 161 is 2.5mm, which is compatible with the needle material 200, ensuring that the needle material 200 is stacked orderly inside the tube without interfering with each other, and that the bottom of the needle rod part 220 of the previous needle material abuts against the needle cap part 210 of the next needle material, so that there is no needle blockage or jamming inside the tube. The needle storage tube 161 is made of Teflon material, and the tube wall is transparent and easy to observe. If the needle material 200 inside the tube is worn, it can be replaced in time.

[0122] like Figure 1 As shown, the needle storage structure 160 further includes a first sensor 162 and a second sensor 163 disposed at both ends of the needle storage tube 161. The first sensor 162 and the second sensor 163 are each provided with a detection hole, and the needle storage tube 161 completely penetrates the detection holes of both sensors. Specifically, the diameter of both detection holes is set to 6mm.

[0123] Both the first sensor 162 and the second sensor 163 are used to sense whether needle material is passing through. Specifically, when the second sensor 163 does not sense needle material passing through within a specified time period, that is, when the needle material in the needle storage tube 161 is insufficient, a needle is fed into the needle storage tube 161 by a vibrating plate, so that the needle material is vertically stacked in the needle storage tube 161 for needle separation processing; when the first sensor 162 senses that the needle material is no longer moving within a specified time period, that is, when the needle material in the needle storage tube 161 is full, the feeding of needles into the needle storage tube 161 is stopped.

[0124] It should be noted that the needle storage tube 161 between the first sensor 162 and the second sensor 163 forms a needle material storage area, wherein the amount of needle material stored can be adjusted by adjusting the installation position of the first sensor 162 and the second sensor 163.

[0125] like Figure 1As shown, the needle feeding structure 170 includes a needle feeding tube 171. One end of the needle feeding tube 171 is fixedly connected to the third tube fixing hole 116b via a tube connector 180, and the other end is fixedly connected to the needle material actuation structure. The inner diameter of the needle feeding tube 171 is adapted to the needle material 200, and the outer diameter is adapted to the diameter of the third tube fixing hole 116b. In a specific embodiment, the third tube fixing hole 116b is a stepped hole with internal threads for fitting and installing the tube connector 180, thereby fixing the needle feeding tube 171. The end face of the needle feeding tube 171 extends to the stepped hole end face of the third tube fixing hole 116b. Preferably, the outer diameter of the needle feeding tube 171 is 6mm; the diameter of the third tube fixing hole 116b is also set to 6mm for limiting the position of the needle feeding tube 171. The needle feeding tube 171 has an inner diameter of 4mm and is adapted to the needle material 200, used to feed the needle material 200 one by one to the needle material execution structure. The needle feeding tube 171 is made of Teflon material, and the tube wall is transparent and flexible.

[0126] like Figure 1 As shown, the needle feeding structure 170 further includes a third sensor 172 disposed on the needle feeding tube 171. The third sensor 172 is provided with a detection hole, through which the needle feeding tube 171 completely passes. Specifically, the diameter of the detection hole is set to 6mm, and it is interference-fitted with the needle feeding tube 171 to fix the third sensor 172.

[0127] The third sensor 172 is used to sense whether needle material is passing through. When the third sensor 172 senses needle material passing through, it indicates that the material distribution is successful, and then the needle is fed into the needle material execution structure. Specifically, when the second driving member 150 drives the second stop member 140 to extend, the needle passage hole 141 is aligned with the third needle passage tube 116a, so that the needle bar portion 220 and needle cap portion 210 of the needle material 200 pass through the needle passage hole 141 and fall freely into the needle feeding tube 171 due to gravity. At this time, the third sensor 172 senses that the needle material has passed through. When the second driving member 150 drives the second stop member 140 to retract, the air blowing blind hole 142 is aligned with the third needle passage tube 116a, and air is blown into the air blowing blind hole 142 through the air pipe to blow the needle material in the needle feeding tube 171 to the needle material execution structure.

[0128] To better understand the structural features and beneficial effects of the needle material dispensing device 100, this utility model provides a needle material dispensing process for PIN needles using the needle material dispensing device 100, which specifically includes the following steps.

[0129] ① The first driving member 130 drives the first stopper 120 to retract, and the second driving member 150 drives the second stopper 140 to retract; meanwhile, needles are fed into the needle storage tube 161 by a vibrating disk, so that the needle materials 200 are vertically stacked, and each needle material 200 is supported by the second stopper 140.

[0130] ② The second driving member 150 drives the second stopper 140 to extend, so that the needle passing through hole 141 is aligned with the third needle passing tube 116a, so that the needle material 200 stacked at the bottom passes through the needle passing through hole 141 and falls into the needle feeding tube 171; meanwhile, the first driving member 130 drives the first stopper 120 to extend synchronously, so that the arc center of the U-shaped needle passing hole 122 extends out of the third needle passing tube 116a, so that the first stopper 120 supports the needle cap part 210 of the needle material 200 stacked at the penultimate position.

[0131] ③ The first driving member 130 drives the first stopper 120 to retract, so that the arc center of the U-shaped needle passing hole 122 is aligned with the third needle passing tube 116a, so that the needle material 200 stacked at the penultimate position integrally passes through the U-shaped needle passing hole 122, and the above needle materials 200 also fall neatly accordingly; meanwhile, the second driving member 150 drives the second stopper 140 to retract, so that the needle materials 200 above and at the penultimate position are vertically stacked on the upper surface of the second stopper 140.

[0132] ④ When the second driving member 150 drives the second stopper 140 to retract, the air blowing blind hole 142 is aligned with the third needle passing tube 116a, and air is blown into the air blowing blind hole 142 through an air pipe to blow the needle material 200 falling into the needle feeding tube 171 to the needle material execution structure.

[0133] Repeat the above steps to perform needle separation on multiple vertically stacked needle materials 200 and send them to the needle material execution structure one by one. At this time, the vertical distance from the upper surface of the first stopper 120 to the upper surface of the second stopper 140 satisfies: B + D < A < 2B - C. Where A is the vertical distance from the upper surface of the first stopper 120 to the upper surface of the second stopper 140; B is the length of the needle material 200; C is the thickness of the needle cap part 210 of the needle material 200, in a specific embodiment, it is 0.4 mm; D is the thickness of the first stopper, in a specific embodiment, it is 0.5 mm.

[0134] It should be noted that the needle-separating device 100 can separate needles one by one or multiple needles, such as separating needles once for every two needles or once for every three needles. Specifically, this can be achieved by adjusting the vertical distance A between the upper surface of the first stop 120 and the upper surface of the second stop 140. This utility model is not limited to this.

[0135] When the needle material dispensing device 100 is used for dispensing, the present invention, on the one hand, selects a vertical direction so that the needle material can fall freely under gravity, thereby minimizing the wear of the surface coating during the movement of the needle material; on the other hand, adopts a staggered needle support method to drive the first stop 120 and the second stop 140 to extend and retract alternately to realize dispensing. With fewer moving parts and fewer factors of failure, the failure rate of jamming will be greatly reduced and the stability will be increased.

[0136] like Figure 8 As shown, this utility model also provides a needle material dispensing system, which includes: one or more needle material dispensing devices 100, a support frame 300, a mounting plate 400, and multiple solenoid valves 500.

[0137] The support frame 300 is fixedly connected to the equipment base to support the needle material dispensing system. The mounting plate 400 is fixedly connected to the support frame 300 to fix and install each needle material dispensing device 100 and each solenoid valve 500. Each needle material dispensing device 100 is mounted on the front of the mounting plate 300 in a staggered manner via multiple mounting brackets to dispense vertically stacked needle materials 200. The specific structure of each needle material dispensing device 100 is the same as in the above-described device embodiment, and will not be described again for simplicity. Each solenoid valve 500 is mounted on the back of the mounting plate 400 and is connected to each needle material dispensing device 100 via an air pipe to provide power to each needle material dispensing device 100.

[0138] In one specific embodiment, the needle material dispensing system includes two needle material dispensing devices 100, which are arranged horizontally and vertically in a staggered manner on the front of the mounting plate 300. Specifically, the third dispensing block 116 of each needle material dispensing device 100 is provided with threaded holes and can be mounted and fixed on the mounting plate 200 by a mounting bracket; and each sensor of the needle material dispensing device 100, including a first sensor 162, a second sensor 163, and a third sensor 172, is respectively mounted and fixed on the mounting plate 200 by sensor brackets.

[0139] In this embodiment, the needle material dispensing system includes two solenoid valve groups, each group comprising three solenoid valves, for providing power to each needle material dispensing device 100. Specifically, the three solenoid valves in each solenoid valve group are a first solenoid valve, a second solenoid valve, and a third solenoid valve. The first solenoid valve is connected to the first drive member 130 via an air pipe, using an air pipe connector at the connection point, for providing power to the first drive member 130, thereby driving the first stop member 120 to extend or retract. The second solenoid valve is connected to the second drive member 150 via an air pipe, using an air pipe connector at the connection point, for providing power to the second drive member 150, thereby driving the second stop member 140 to extend or retract. The third solenoid valve is connected to the elbow joint 190 via an air pipe, for blowing air into the air blowing blind hole 142, thereby blowing the needle material 200 in the needle feeding tube 171 to the needle material actuation structure.

[0140] In summary, this utility model provides a needle material separating device. It features a vertical first needle tube within a needle-passing plate, and a first needle-separating port and a second needle-separating port on the side of the needle-passing plate, connected to the first needle tube. A first driving component drives a first stop to insert into the first needle-separating port for extension and retraction, and a second driving component drives a second stop to insert into the second needle-separating port for extension and retraction. This utility model also provides a needle material separating system utilizing the aforementioned needle material separating device. This utility model offers the following advantages: by employing a staggered needle-supporting method, it achieves needle-separation processing of vertically stacked needle materials, effectively reducing the jamming failure rate, increasing separating stability, and preventing wear on the surface coating of the needle materials. It solves the technical problems of high jamming failure rate, poor stability, and easy damage to needle materials in existing needle material separating methods.

[0141] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0142] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
