Although the existing solutions can meet the demand to some extent, there are still some deficiencies, first, the traditional equipment mostly uses cylinder in the separation of needle insertion, which is easy to cause needle insertion accumulation or position deviation;Second, manual operation or simple mechanical structure still cannot meet the requirements of high-speed production in the speed and efficiency of needle feeding, and the accuracy and reliability of needle feeding also need to be further improved. SUMMARY

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a kind of needle separation and feeding device, for solving the problems of needle insertion accumulation or position deviation, low efficiency and poor precision in the prior art.

[0004] To achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical scheme:

When needle insertion reaches the end of linear vibration table, enter the action range of needle separation assembly. Needle separation assembly uses mechanical structure to let single needle insertion pass, immediately close and block subsequent needle insertion;Once needle insertion reaches specified position, detection device will send signal to needle feeding assembly, and needle feeding assembly accurately transfers needle insertion in preset position on needle separation assembly and moves to drop pipe according to preset action program.

[0007] In an embodiment of the utility model, the needle isolation assembly comprises a needle guide plate, needle isolation plates arranged on both sides of the needle guide plate and embedded in the needle guide plate, the middle part of the needle isolation plate is arranged on the needle guide plate through a rotating pin, one end of the needle isolation plate away from the needle guide plate extends a needle isolation block, and a spring is arranged between the other end of the needle isolation plate and the needle guide plate; the two needle isolation blocks can abut against each other under the thrusting action of the spring and isolate the insertion needles on the needle guide plate.

[0008] The above technical solution is realized, the surface of the needle guide plate is provided with a guide rail, so that the insertion needle can stably move along a predetermined path after entering the needle isolation assembly, deviation or lateral turning of the insertion needle is avoided, the needle isolation plates are arranged on both sides of the needle guide plate and embedded in the needle guide plate, and the middle part is connected with the needle guide plate through a rotating pin. The spring is arranged at one end away from the needle isolation block and provides an outward thrusting force, so that the two needle isolation blocks are tightly abutted against each other and the state of the needle isolation is maintained.

[0009] In an embodiment of the utility model, the needle feeding assembly comprises a rotary air cylinder, a sliding table air cylinder arranged on the rotary air cylinder and a clamping air cylinder arranged on the sliding table air cylinder.

[0010] The above technical solution is realized, when the detection device sends a signal that the insertion needle has reached a preset position, firstly, the rotary air cylinder turns the sliding table air cylinder and the clamping air cylinder to the direction of the insertion needle, after rotation, the sliding table air cylinder is immediately started and smoothly pushed to the insertion needle. At the same time, the clamping air cylinder also starts to act synchronously, and the insertion needle is firmly gripped by the clamping jaw. After successfully gripping the insertion needle, the sliding table air cylinder quickly retreats according to a preset return path, and the rotary air cylinder adjusts the angle again according to the position of the material falling pipe. After the sliding table air cylinder brings the insertion needle to the accurate position above the material falling pipe, the clamping air cylinder releases the clamping, the insertion needle falls into the material falling pipe under the action of gravity, and a complete needle feeding process is completed.

[0011] In an embodiment of the utility model, the clamping air cylinder comprises an air cylinder body, a sliding rail arranged on the air cylinder body in the vertical direction, and two clamping jaws slidingly arranged on the sliding rail.

[0012] The above technical solution is realized, the sliding rail is arranged on the air cylinder body in the vertical direction and provides an accurate guide path for the movement of the clamping jaw. The sliding part is tightly attached to the sliding rail, and the shape thereof is highly matched with the groove or track shape of the sliding rail, so that smooth and stable up-and-down sliding on the sliding rail is ensured. The surface of the clamping part is processed with fine anti-skid lines, and when the clamping jaw is closed, the lines can effectively increase the friction force between the insertion needle and the clamping jaw and prevent the insertion needle from slipping during the transfer process.

[0014] The above technical scheme is realized, when two clamping jaws are separated, the clamping jaws are in an open state for receiving the insertion needle. At the same time, the two needle isolation plates are folded towards each other under the action of the spring, and the two needle isolation blocks are in close contact, playing a role of isolating and blocking the insertion needle. At this time, the upper clamping part of the clamping jaw is embedded above the two needle isolation blocks, and the lower clamping part is embedded below the two needle isolation blocks. With the folding of the clamping jaw, the two clamping parts simultaneously apply a pushing force to the two needle isolation blocks on the sides. Since the middle part of the needle isolation plate is arranged on the guide plate through the rotating pin, and the spring between the needle isolation plate and the guide plate is compressed when subjected to the pushing force of the clamping jaw, the two needle isolation blocks are separated from each other under the action of the clamping jaw. After the clamping jaw successfully grabs the insertion needle, the needle isolation plate returns to the initial folded state under the action of the spring, and the two needle isolation blocks are in close contact again to isolate the next insertion needle.

[0015] In an embodiment of the utility model, the guide rail, the needle isolation assembly, the clamping cylinder and the blanking pipe on the linear vibration table are each provided with multiple groups.

[0018] The above technical scheme is realized, and since the sensor is directly arranged above the needle isolation assembly, it can detect the position of the insertion needle at close range and intuitively, greatly improving the accuracy and reliability of detection. Whether it is a small insertion needle or a larger size insertion needle, the sensor can timely and accurately perceive the existence and position change of the insertion needle, providing accurate signal support for subsequent needle feeding operations.

[0019] In an embodiment of the utility model, the rotating cylinder is provided with a blowing pipe aligned with the blanking pipe.

[0020] The above technical scheme realizes that the clamping air cylinder starts working while grabbing the pin, saves the time for separately preparing the alignment and air blowing of the air blowing pipe, makes the whole pin feeding process more compact and efficient, and the pin can reach the next pin station from the blanking pipe faster under the air blowing assistance, reduces the residence time of the pin in the transfer process, and greatly improves the number of pins fed per unit time.

[0021] As described above, the pin isolation and feeding device has the following beneficial effects:

[0022] The pin isolation assembly of the device adopts a unique structure design and is composed of a guide plate, a pin isolation plate, pin isolation blocks and springs. The guide rail on the guide plate can ensure the stable forward movement of the pin and avoid deviation or lateral turning. The two pin isolation blocks abut against each other under the pushing action of the springs, and can accurately isolate the pin.

[0023] When the clamping jaw of the clamping air cylinder acts, the pin can be directly released by pushing the pin isolation block, and the action is rapid and smooth. Compared with the complex process of inflation, ejection and return of the air cylinder in the traditional air cylinder ejection mode, the pin isolation assembly reduces unnecessary time consumption and improves the speed of pin isolation.

[0024] The combination of the rotary air cylinder, the sliding table air cylinder and the clamping air cylinder enables the pin to be accurately positioned in three-dimensional space, and is suitable for pins of different lengths and shapes.

DETAILED DESCRIPTION

[0034] The implementation of the present application will be described by specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] Please refer to Figures 1 to 6 The present application provides a needle isolation and feeding device, comprising a vibration disc 1 for orderly arranging pins 2 in the same direction; a linear vibration table 3 for receiving the arranged pins 2 from the vibration disc 1 and conveying the pins 2 along a set linear track 31; a needle isolation assembly arranged at the end of the linear vibration table 3 and separating the pins 2 conveyed by the linear vibration table 3 one by one; a detection device for detecting whether the pins 2 on the needle isolation assembly reach a preset position; and a needle feeding assembly for transferring the pins 2 on the needle isolation assembly to a blanking pipe 4.

[0036] The vibration disc 1 utilizes its own vibration characteristics and internal special spiral track or guide structure to gradually guide the disordered pins 2 to a unified direction, so that the pins 2 are orderly arranged and then enter the linear vibration table 3. The pins 2 on the linear vibration table 3 are conveyed forward along the set linear track 31, and at the same time, the spacing between the pins 2 can be adjusted to make the pins 2 more evenly distributed and avoid congestion. When the pins 2 reach the end of the linear vibration table 3, they enter the action range of the needle isolation assembly. The needle isolation assembly uses mechanical structure to allow a single pin 2 to pass through and then blocks the subsequent pins 2. Once the pins 2 reach the designated position, the detection device sends a signal to the needle feeding assembly, and the needle feeding assembly accurately grasps and transfers the pins 2 at the preset position on the needle isolation assembly to the blanking pipe 4 according to the preset action program.

[0037] The needle isolation assembly comprises a needle guide plate 5 and a needle isolation plate 6 embedded in the needle guide plate 5 and arranged on both sides of the needle guide plate 5. The middle part of the needle isolation plate 6 is arranged on the needle guide plate 5 through a rotating pin 7, one end of the needle isolation plate 6 away from the needle guide plate 5 extends a needle isolation block 8, and a spring 9 is arranged between the other end of the needle isolation plate 6 and the needle guide plate 5. The two needle isolation blocks 8 can abut against each other under the pushing action of the spring 9 and isolate the pins 2 on the needle guide plate 5.

[0038] The guide needle plate 5 is provided with guide rails to ensure that the inserted needle 2 can move steadily along the predetermined path after entering the needle isolation assembly, avoiding deviation or lateral turning of the inserted needle 2. The needle isolation plates 6 are arranged in pairs on both sides of the guide needle plate 5 and embedded therein, and the middle part is connected to the guide needle plate 5 through a rotating pin 7. The spring 9 is arranged at one end away from the needle isolation block 8 and provides an outward thrusting force, so that the two needle isolation blocks 8 are tightly abutted, maintaining the state of the needle isolation.

[0039] The needle feeding assembly comprises a rotating cylinder 10, a sliding table cylinder 11 arranged on the rotating cylinder 10, and a clamping cylinder 12 arranged on the sliding table cylinder 11.

[0040] When the detection device sends a signal that the inserted needle 2 has reached the preset position, the rotating cylinder 10 first rotates the sliding table cylinder 11 and the clamping cylinder 12 as a whole to the direction of the inserted needle 2. After rotating in place, the sliding table cylinder 11 is immediately started and smoothly pushed towards the inserted needle 2. At the same time, the clamping cylinder 12 also starts to act synchronously, and the clamping jaw 123 firmly grips the inserted needle 2. After successfully grabbing the inserted needle 2, the sliding table cylinder 11 quickly retreats along the preset return path, and the rotating cylinder 10 adjusts the angle again according to the position of the material falling pipe 4. After the sliding table cylinder 11 brings the inserted needle 2 to the accurate position above the material falling pipe 4, the clamping cylinder 12 releases the clamping, and the inserted needle 2 falls into the material falling pipe 4 under the action of gravity, completing a complete needle feeding process.

[0041] The clamping cylinder 12 comprises a cylinder body 121, a sliding rail 122 arranged vertically on the cylinder body 121, and two clamping jaws 123 slidingly arranged on the sliding rail 122. The clamping jaw 123 comprises a sliding part 1231 sliding in the sliding rail 122, a clamping part 1232 for clamping the inserted needle 2, and a connecting part 1233 connecting the sliding part 1231 and the clamping part 1232.

[0042] The sliding rail 122 is arranged vertically on the cylinder body 121 and provides an accurate guide path for the movement of the clamping jaw 123. The sliding part 1231 closely fits on the sliding rail 122, and its shape is highly adapted to the groove or track shape of the sliding rail 122, ensuring smooth and stable up-and-down sliding on the sliding rail 122. The surface of the clamping part 1232 is processed with fine anti-slip lines, which can effectively increase the friction between the clamping jaw 123 and the inserted needle 2 when the clamping jaw 123 is closed, preventing the inserted needle 2 from slipping during the transfer process.

[0043] When the two clamping jaws 123 are separated from each other, the two needle isolation plates 6 are folded towards each other, and the upper clamping part 1232 is embedded above the two needle isolation blocks 8, and the lower clamping part 1232 is embedded below the two needle isolation blocks 8. When the two clamping jaws 123 are folded towards each other, the two clamping parts 1232 simultaneously push the two side needle isolation blocks 8 and make the two needle isolation blocks 8 move away from each other, thereby releasing the inserted needle 2.

[0044] When the two clamping jaws 123 are separated from each other, at this time the clamping jaws 123 are in an open state for receiving the pin 2. At the same time, the two spacer plates 6 are folded towards each other under the action of the spring 9, and the two spacer blocks 8 are tightly abutted, playing a role of isolating and blocking the pin 2. At this time, the upper clamping part 1232 of the clamping jaw 123 is embedded in the upper part of the two spacer blocks 8, and the lower clamping part 1232 is embedded in the lower part of the two spacer blocks 8. With the folding of the clamping jaw 123, the two clamping parts 1232 simultaneously apply a pushing force to the spacer blocks 8 on both sides. Since the middle part of the spacer plate 6 is arranged on the guide plate 5 through the rotating pin 7, and the spring 9 between the spacer plate 6 and the guide plate 5 will be compressed when subjected to the pushing force of the clamping jaw 123, so that the two spacer blocks 8 are away from each other under the action of the clamping jaw 123. After the clamping jaw 123 successfully grabs the pin 2, the spacer plate 6 returns to the initial folded state under the action of the spring 9, and the two spacer blocks 8 are tightly abutted again to isolate the next pin 2.

[0045] The guide rail, the spacer assembly, the clamping cylinder 12 and the blanking pipe 4 on the linear vibration table 3 are all correspondingly provided with multiple groups. The arrangement of multiple groups of components enables the device to simultaneously process multiple pins 2, greatly improving the speed and quantity of pin feeding. At the same time, the reasonable layout of multiple groups of components enables the device to maximize the function in a limited space.

[0046] The detection device is a sensor 13 arranged above the spacer assembly. Since the sensor 13 is directly arranged above the spacer assembly, it can detect the position of the pin 2 at close range and intuitively, greatly improving the accuracy and reliability of detection. Whether it is a small pin 2 or a larger size pin 2, the sensor 13 can timely and accurately perceive the existence and position change of the pin 2, providing accurate signal support for subsequent pin feeding operations.

[0047] The rotating cylinder 10 is provided with a blowing pipe 14 aligned with the blanking pipe 4. The clamping cylinder 12 starts working at the same time as the pin 2 is grabbed, saving the time for separately aligning and blowing the blowing pipe 14, making the whole pin feeding process more compact and efficient. The pin 2 can reach the next pin 2 station from the blanking pipe 4 faster with the aid of blowing, reducing the residence time of the pin 2 in the transfer process, and greatly improving the number of pins fed per unit time.

[0048] The above embodiments only exemplarily illustrate the principle and effect of the present application, and are not used to limit the present application. All equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical concept disclosed by the present application should still be covered by the claims of the present application.
