DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 8 The utility model provides a nozzle extraction tool.

[0031] The suction nozzle tooling includes a supporting component 100 and a plurality of suction nozzle components 200 arranged in an array; the plurality of suction nozzle components 200 arranged in an array are arranged on the supporting component 100, and each set of suction nozzle components 200 includes a base 210 and a rotating hook 220, a rotating shaft 230 is arranged on the base 210, the rotating hook 220 is rotatably connected to the rotating shaft 230, and the rotating hook 220 is provided with a suction nozzle slot 221, and the suction nozzle slot 221 is used to clamp the needle bed suction nozzle 300; a torsion spring 400 is sleeved on the rotating shaft 230, and a force-bearing torsion arm 410 of the torsion spring 400 is arranged on the side of the rotating hook 220 rotating inwardly, and the rotating hook 220 is squeezed by the needle bed suction nozzle 300 and can overcome the force of the torsion spring 400 to rotate inwardly, and the rotating hook 220 can rebound under the force of the torsion spring 400.

[0032] Specifically, when the rotating hook 220 is in the initial state, the rotating hook 220 is in the extreme position, the rotating hook 220 is stretched outward, and the torsion spring 400 has two torsion arms, one of which is the force-bearing torsion arm 410, which can be rotated and compressed when the rotating hook 220 is squeezed and rotated inward, and the other torsion arm is in an idle state. The process of pulling out the needle bed suction nozzle 300 is as follows: in the initial state, the rotating hook 220 and the base 210 are in a vertical state, the negative pressure cup 500 drives the needle bed suction nozzle 300 to move downward, and the needle bed suction nozzle 300 squeezes the top of the rotating hook 220. The rotating hook 220 is squeezed by the needle bed suction nozzle 300 and rotates inward. At this time, the force-bearing torsion arm 410 of the torsion spring 400 is compressed to store elastic force until the needle bed suction nozzle 300 completely falls into the suction nozzle slot 221. The rotating hook 220 is not squeezed by the needle bed suction nozzle 300, the torsion spring 400 is elastically released, and the rotating hook 220 rotates and rebounds under the elastic action of the torsion spring 400, so that the rotating hook 220 returns to the initial position (such as Figure 1 As shown in ), when the negative pressure cup 500 rises again, the needle bed suction nozzle 300 is stuck due to the limiting force of the rotating hook 220, and the needle bed suction nozzle 300 cannot move upward, so that the needle bed suction nozzle 300 is pulled out of the negative pressure cup 500. In this way, the rotating hook 220 is automatically clamped and removed by the force of the torsion spring 400. The purely automatic mechanical structure can automatically pull out the suction nozzle without the need for an additional power mechanism, thereby reducing energy consumption. The overall structure of the rotating hook 220 is stable, can be used repeatedly, has a long service life, and has a simple structure.

[0033] See also Figure 6Furthermore, a wire groove 222 is provided on the rotating hook 220, and the force-bearing torsion arm 410 of the torsion spring 400 is provided in the wire groove 222, and the force-bearing torsion arm 410 of the torsion spring 400 is fitted with the rotating hook 220. The wire groove 222 is used to accommodate the force-bearing torsion arm 410 of the torsion spring 400. In order to completely confine the force-bearing torsion arm 410 of the torsion spring 400 in the wire groove 222 and prevent the force-bearing torsion arm 410 of the torsion spring 400 from running around, the depth of the wire groove 222 should be set to be very deep. In order to ensure that the force-bearing torsion arm 410 of the torsion spring 400 can be stably located in the wire groove 222, in other embodiments, a limit block can be provided at the top of the wire groove 222 to lock the force-bearing torsion arm 410 of the torsion spring 400 in the wire groove 222. Of course, the wire groove 222 may also be just a groove, as long as the torsion spring 400 can provide a pulling force to the rotating hook 220 to ensure that the rotating hook 220 can rebound.

[0034] See also Figure 3 and Figure 7 Furthermore, the rotating hook 220 is provided with a guide slope 223 at the edge of the nozzle slot 221, and the guide slope 223 is used to guide the needle bed nozzle 300 into the nozzle slot 221. In this way, when the negative pressure cup 500 drives the needle bed nozzle 300 to move, the needle bed nozzle 300 can move along the guide slope 223 into the nozzle slot 221, providing a transition for the movement of the needle bed nozzle 300, so that the needle bed nozzle 300 can be guided and installed into the nozzle slot 221 more smoothly.

[0035] See also Figure 6 to Figure 7 Furthermore, the nozzle slot 221 is semicircular. The cross section of the needle bed nozzle 300 is generally circular. By setting the nozzle slot 221 to be semicircular, the needle bed nozzle 300 can be easily locked after the rotating hook 220 rotates.

[0036] See also Figure 7 Further, the rotating hook 220 includes a rotating shaft 224 and a handle 225 integrally formed on the rotating shaft 224. The handle 225 can be used to press the top of the needle bed nozzle 300 to pull out the needle bed nozzle 300. The rotating shaft 224 is rotatably connected to the rotating shaft 230. The handle 225 extends toward the front side along the rotating shaft 224, and the handle 225 has a nozzle slot 221, which can facilitate the handle 225 to clamp the needle bed nozzle 300 out.

[0037] See also Figure 3 , Figure 6 , Figure 7, further, the rotating shaft 224 has a rotating curved surface 226, a first stop plane 227 and a second stop plane 228 connected in sequence, the rotating curved surface 226 is used to avoid the rotating stroke of the rotating hook 220, and the first stop plane 227 is perpendicular to the second stop plane 228; when the rotating hook 220 rebounds to the limit position, the first stop plane 227 abuts against the inner wall surface of the base 210, and the second stop plane 228 and the upper surface of the base 210 are spliced ​​into a plane. Specifically, the rotating hook 220 has two positions, and the rotating hook 220 rotates back and forth between these two positions. In the initial position, due to the abutment and restriction of the first stop plane 227 of the rotating hook 220 and the inner wall surface of the base 210, the rotating hook 220 is restricted and cannot continue to rotate. At this time, the rotating hook 220 is perpendicular to the base 210. As the negative pressure cup 500 drives the needle bed suction nozzle 300 to be pressed down, the setting of the rotating curved surface 226 can avoid the rotation path of the rotating hook 220, and the rotating hook 220 is pressed down and rotated inward. When the needle bed suction nozzle 300 is pressed into place, the rotating hook 220 rebounds until the first stop plane 227 of the rotating hook 220 abuts against the inner wall surface of the base 210, and the second stop plane 228 is spliced ​​with the upper surface of the base 210 to form a plane. Then the negative pressure cup 500 continues to drive the needle bed suction nozzle 300 to rise and clamp the needle bed suction nozzle 300 out.

[0038] See also Figure 4 Furthermore, the base 210 includes a base body 211 and four lugs 212 integrally formed on the base body 211, each lug 212 is provided with an axis hole 213, and each axis hole 213 is used for the rotation axis 230 to pass through. The rotation axis 230 can be fixed to the base 210 in an integrally formed manner, and it is sufficient that the rotating hook 220 can rotate around the rotation axis 230.

[0039] Continue reading Figure 4 Furthermore, a first receiving groove 214, a second receiving groove 215, and a third receiving groove 216 are sequentially formed between adjacent lugs 212, and there are two torsion springs 400, which are respectively disposed in the first receiving groove 214 and the third receiving groove 216 and sleeved on the rotating shaft 230, and the rotating shaft 224 is disposed in the second receiving groove 215. At the same time, the wire groove 222 on the rotating hook 220 is disposed on both sides of the rotating hook 220, and the force-bearing torsion arms 410 of the two torsion springs 400 are respectively disposed in the wire groove 222 on both sides of the rotating hook 220.

After the nozzle extraction component 200 extracts the needle bed nozzle 300, the needle bed nozzle 300 falls into the nozzle box 130 from the nozzle slot 221, and the nozzle box 130 is used to collect the needle bed nozzles 300 removed by the nozzle extraction component 200, so as to facilitate unified processing later.
