For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0024] Figures 1 to 4 The utility model shows some preferred embodiments of the air duct machine. The universal horizontal terminal number PIN counting automatic machine can be used for high-speed counting of terminal strips.

[0025] Figures 1 to 4The present invention shows an automatic terminal counting machine in one embodiment, which may include a frame 100, a storage turntable 110, a loading turntable 120, a trough 200, and a counting assembly 300; the storage turntable 110 and the loading turntable 120 are respectively arranged on both sides of the frame 100; the trough 200 is arranged between the storage turntable 110 and the loading turntable 120, one end of the trough 200 faces the loading turntable 120, and the other end faces the counting assembly 300; the counting assembly 300 is arranged between the trough 200 and the storage turntable 110, and the counting assembly 300 is arranged between the trough 200 and the storage turntable 110. 0 includes a mounting frame 310, a counting sensor unit 350, an axial positioning wheel group 320, and a radial positioning wheel group 330. The mounting frame 310 is set on the frame 100, and the counting sensor unit 350 is movably connected to the frame 100. The axial positioning wheel group 320, the radial positioning wheel group 330, and the counting assembly 300 are sequentially arranged on the mounting frame 310 along the forward direction of the terminal belt. The axial positioning wheel group 320 abuts and limits the upper and lower ends of the terminal belt. The radial positioning wheel group 330 is arranged below the terminal belt and abuts and limits the two sides of the terminal belt.

[0026] The terminal strip is quickly stored in the storage turntable 110 by rotating the storage turntable 110. The terminal strip starts from the loading turntable 120 and is guided by the material trough 200 to make the terminal strip move linearly relative to the frame 100. The axial positioning wheel group 320 limits the upper and lower ends of the terminal strip so that the upper and lower ends of the terminal strip can form a vertical terminal strip after axial rotation to enter the counting sensor unit 350. The radial positioning wheel group 330 limits the horizontal position of the terminal strip so that the terminal strip can maintain the same position and enter the counting sensor unit 350. The terminal strip maintains verticality and enters the counting sensor unit 350 at the same position, which can maximize the consistency of the terminal position during detection and reduce the error that may be generated by the detected terminal to the limit. Even at 6000 per minute, the counting sensor unit 350 can still maintain high-precision counting, greatly improving the counting efficiency and significantly reducing the occurrence of false detection and missed detection.

[0027] It can be understood that the terminal strip is initially installed in the loading turntable 120 , and one end of the terminal strip is pulled out from the loading turntable 120 , passes through the material trough 200 and the counting assembly 300 in sequence, and finally reaches the storage turntable 110 .

[0028] It can be understood that the counting sensor unit 350 is mainly used to detect the number of terminal pins on the terminal strip. Because the terminals are packaged on the tape, generally only the terminal pins are exposed. If one terminal corresponds to several pins, the number of terminals can be obtained by dividing the number of pins in the technical sensor unit.

[0029] In a specific embodiment, Figure 3It is shown that guide parts 210 are provided at both ends of the material trough 200. The guide parts 210 are trumpet-shaped, so that when the terminal strip enters the material trough 200, it will not collide with the corners of the material trough 200 and cause scratches.

[0030] In a specific embodiment, the rack 100 is further provided with a plurality of spare trays 130 , which are used to load uncounted terminal strip rolls or counted terminal strip rolls.

[0031] Figure 4 In one embodiment, the counting sensor unit 350 may include a through-beam photoelectric sensor and a bridge. The bridge is movably connected to the mounting frame 310, and the through-beam photoelectric sensor is mounted on the bridge. The through-beam photoelectric sensor has the advantages of high sensitivity and extremely short detection time, and is suitable for detecting the number of terminal pins at high speed.

[0032] Figure 4 In one embodiment, the counting sensor unit 350 shown may include a bridge movably connected to the mounting frame 310. The bridge includes a body extending horizontally from the mounting frame 310 and provided with two vertically upward-facing legs 351. The through-beam photoelectric sensors are positioned opposite each other on the two legs 351. The bridge can move relative to the mounting frame 310, and the through-beam photoelectric sensors can move up and down as a whole to adjust the detection position.

[0033] Figure 4 In one embodiment, the counting sensor unit 350 may include a foot 351 with a deep groove 352 that matches the shape of the through-beam photoelectric sensor. The deep groove 352 extends from the top of the foot 351 to the body, and the through-beam photoelectric sensor can adjust its relative position within the deep groove 352. The deep groove 352 facilitates the vertical adjustment of the through-beam photoelectric sensor within the deep groove 352 and helps protect the through-beam photoelectric sensor from external damage.

[0034] Figure 4 The axial positioning wheel assembly 320 shown in one embodiment may include a first positioning wheel 321 and a second positioning wheel 322 disposed transversely to the mounting frame 310. Concave notches 323 are provided in the middle of the first and second positioning wheels 321 and 322. The concave notches 323 are used to pass through and limit the position of the terminal strip. The terminal strip passes through and is limited by the concave notches 323.

[0035] In a specific embodiment, the first positioning wheel 321 is composed of two sub-wheels to form a wheel group, and the outer circumferences of the two sub-wheels are chamfered to form a concave notch 323 after chamfering.

[0036] Furthermore, the distance between the first positioning wheel 321 and the second positioning wheel 322 is adjustable, and the distance adjustment is determined according to the specific shape of the terminal strip.

[0037] Figure 4 The radial positioning wheel set 330 can include a third positioning wheel 331 and a fourth positioning wheel 333, which are vertically arranged on the mounting frame 310. The third positioning wheel 331 is provided with a large wheel 332 on the upper portion, and the diameter of the large wheel 332 is larger than the lower portion of the third positioning wheel 331. The fourth positioning wheel 333 is provided with a small wheel 334 on the upper portion, and the diameter of the small wheel 334 is smaller than the lower portion of the fourth positioning wheel 333. The large wheel 332 and the small wheel 334 abut each other, and the terminal tape passes through the contact position of the large wheel 332 and the small wheel 334.

[0038] Figure 3 And Figure 4 The counting assembly 300 can include a biasing unit 340, which is arranged on the rack 100. The biasing unit 340 includes two groups of vertically arranged biasing rods 341, which are arranged between the axial positioning wheel set 320 and the radial positioning wheel set 330. The height of the biasing rods 341 is higher than the height of the terminal tape, and the gap between the two biasing rods 341 is not in the same straight line as the radial positioning wheel set 330.

[0039] Figure 3 And Figure 4 The counting assembly 300 can include two groups of biasing units 340, axial positioning wheel sets 320, and radial positioning wheel sets 330, which are mirror arranged around the center of the counting sensor unit 350. The mounting frame 310 is provided with a plurality of vertically arranged long grooves 360, which pass through the mounting frame 310. The counting sensor unit 350, the axial positioning wheel set 320, and the radial positioning wheel set 330 are movably arranged in the long grooves 360, and the relative height of the counting sensor unit 350, the axial positioning wheel set 320, and the radial positioning wheel set 330 can be adjusted in the long grooves 360.

[0040] Figure 1 And Figure 2 The storage turntable 110 can include a central shaft 111 and a driving element 112 arranged at the center of the storage turntable 110. The central shaft 111 is connected to the output end of the driving element 112, and is driven to rotate by the driving element 112. The storage turntable 110 is controlled to rotate by the driving element 112.

[0041] In a specific embodiment, the driving element 112 is a speed-regulating motor, which can adjust the speed of the turntable, thereby adjusting the speed and tension of the terminal tape. As the terminal tape is continuously wound on the storage disc, the diameter of the terminal tape roll becomes larger and larger. Therefore, a speed-regulating motor is needed to adjust the speed of the terminal tape.

[0042] In a specific embodiment, a speed regulating motor is also provided at the bottom of the loading turntable 120 .

[0043] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
