DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model provides a collecting device, the structure of which is as follows: Figure 1 - Figure 2 As shown, it is used to collect the resistors 11 after the legs of the resistor belt 1 are bent, including a bending device 2, a resistor collecting device 3 and a pin collecting device 4.

[0025] The leg bending device 2 includes a frame 21, on which a guide rail 22, a gear 23, a curved knife 24 and a cutter 25 are sequentially arranged along the length direction of the frame 21. The guide rail 22 is used to carry the resistance belt 1, the gear 23 is used to drive the resistance belt 1 to move, the curved knife 24 is used to bend the legs of the resistor 11, and the cutter 25 is used to cut off the redundant pins 12 on the resistor 11.

[0026] The resistor collecting device 3 includes a first collecting tray 31 disposed on the frame 21 . The first collecting tray 31 is located directly below the curved blade 24 . The top of the first collecting tray 31 is open.

[0027] The pin collecting device 4 includes a second collecting tray 41 arranged on the frame 21, the second collecting tray 41 is located directly below the first collecting tray 31, the top of the second collecting tray 41 is open, and the bottom of the first collecting tray 31 is provided with leakage holes 32 arranged in an array, and the leakage holes 32 are used for the pins 12 to pass through.

[0028] When in use, the resistor belt 1 is placed on the guide rail 22, and the gear 23 is rotated. The gear 23 drives the resistor belt 1 to move, and the curved knife 24 bends the pins 12 on both sides of the resistor 11 into a predetermined angle, and the cutter 25 cuts off the excess parts of the pins 12. The bent resistors 11 and the cut pins 12 fall into the first collecting tray 31, and the pins 12 pass through the leakage holes 32 and fall into the second collecting tray 41. The resistors 11 and the pins 12 are directly collected separately without the need for manual sorting, thereby improving production efficiency.

[0029] In the utility model, the resistor 11 with bent legs and the pin 12 with cut off both fall into the first collecting tray 31, and the pin 12 passes through the leakage hole 32 and then falls into the second collecting tray 41. The resistor 11 and the pin 12 are directly collected separately without manual sorting, thereby improving production efficiency.

[0030] To drive the first collecting tray 31 to vibrate, please refer to Figure 1 In a preferred embodiment, the frame 21 is provided with a vibration mechanism 5 for driving the first collecting tray 31 to vibrate.

[0031] During use, after the pin 12 falls into the first collecting tray 31, the pin 12 may be misaligned with the leakage hole 32, causing the pin 12 to be unable to fall into the second collecting tray 41. The vibration mechanism 5 drives the first collecting tray 31 to vibrate, so that the pin 12 passes through the leakage hole 32 and falls into the second collecting tray 41, thereby improving production efficiency.

[0032] In order to drive the first collecting tray 31 to slide in one direction, please refer to Figure 1 In a preferred embodiment, the vibration mechanism 5 includes a frame plate 51 slidably connected to the frame 21 for accommodating the first collecting tray 31, a motor 52 is installed on the frame 21, a cam 53 is fixedly connected to the output shaft of the motor 52, the cam 53 is perpendicular to the output shaft, a protrusion 54 intermittently abutting against the cam 53 is fixedly connected to one side of the frame plate 51, and a reset component 6 for resetting the frame plate 51 is provided on the frame 21.

[0033] When in use, start the motor 52, and the motor 52 drives the cam 53 to rotate. When the cam 53 contacts the protrusion 54, the cam 53 pushes the frame plate 51 to move, thereby driving the first collecting tray 31 to move. When the cam 53 separates from the protrusion 54, under the action of the reset component 6, the first collecting tray 31 slides in the opposite direction, and the first collecting tray 31 vibrates in this reciprocating manner. The structure is simple and the vibration effect is good.

[0034] To drive the first collecting tray 31 to slide in the reverse direction, please refer to Figure 2 In a preferred embodiment, an elastic layer 55 is bonded to the inner side of the frame plate 51, and the elastic layer 55 is a rubber pad.

[0035] During use, when the first collecting tray 31 is clamped in the frame plate 51, the elastic layer 55 is squeezed and deformed, so that the first collecting tray 31 and the frame plate 51 fit more closely and are fixed more firmly.

[0036] To make the cam 53 rotate more smoothly, please refer to Figure 2 In a preferred embodiment, the side of the cam 53 close to the protrusion 54 is arc-shaped.

[0037] When in use, the contact area between the cam 53 and the lug 54 is reduced, and the friction between the cam 53 and the lug 54 is reduced, which not only makes the cam 53 rotate more smoothly, but also reduces the wear of the cam 53 and the lug 54, and improves the service life of the cam 53 and the lug 54.

[0038] In order to reduce the wear of the cam 53 and the protrusion 54, please refer to Figure 2 In a preferred embodiment, a wear-resistant layer 56 is provided on one side of the cam 53 close to the protrusion 54, and the material of the wear-resistant layer 56 is polyurethane.

[0039] When in use, the wear resistance of the cam 53 is further improved, and the service life of the cam 53 is increased.

[0040] To drive the first collecting tray 31 to slide in the reverse direction, please refer to Figure 2 In a preferred embodiment, the reset assembly 6 includes a spring 61 arranged between the frame plate 51 and the frame 21, one end of the spring 61 is fixedly connected to an end of the frame plate 51 away from the protrusion 54, and the other end of the spring 61 is fixedly connected to the frame 21. The spring 61 is in a compressed state, and the spring 61 causes the frame plate 51 to have a tendency to slide toward the cam 53.

[0041] When in use, when the cam 53 abuts against the protrusion 54 and pushes the first collecting tray 31 to slide, the spring 61 is in a compressed state. When the cam 53 is separated from the protrusion 54, the first collecting tray 31 can slide in the opposite direction under the action of the restoring force of the spring 61.

[0042] In order to align the first collecting tray 31 with the second collecting tray 41, please refer to Figure 2 In a preferred embodiment, positioning rods 42 are fixedly connected to both sides of the second collecting tray 41, and positioning grooves 43 for the positioning rods 42 to slide are provided on both sides of the frame 21, and one end of the positioning groove 43 is open.

[0043] When in use, align the positioning rod 42 with the positioning groove 43 and slide it along the positioning groove 43, so that the second collecting tray 41 is aligned with the first collecting tray 31, making it easier for the pins 12 to fall into the second collecting tray 41, reducing the possibility of the pins 12 falling outside the second collecting tray 41 and improving the collection effect.

[0044] To fix the second collecting tray 41, please refer to Figure 2 In a preferred embodiment, a nut 44 is threadedly connected to the positioning rod 42 , and the nut 44 is used to tighten against the frame 21 and fix the second collecting tray 41 .

[0045] When in use, during the process of bending and cutting the legs, the frame 21 will produce a certain amount of shaking, and the frame 21 will drive the second collecting tray 41 to shake, causing the second collecting tray 41 to shift, and the pins 12 are easy to fall outside the second collecting tray 41. The nut 44 is tightened to fix the second collecting tray 41, reducing the possibility of the second collecting tray 41 shifting, making it easier for the pins 12 to fall into the second collecting tray 41.

[0046] In order to improve the stability of the second collecting tray 41, please refer to Figure 2 In a preferred embodiment, a washer 45 is sleeved on the positioning rod 42 , and the washer 45 is located between the nut 44 and the frame 21 .

[0047] When in use, the contact area between the nut 44 and the frame 21 is increased, further improving stability.

[0048] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of a collecting device of the utility model is described in detail: the resistor belt 1 is placed on the guide rail 22, the gear 23 is rotated, the gear 23 drives the resistor belt 1 to move, the curved knife 24 bends the pins 12 on both sides of the resistor 11 into a predetermined angle, and the cutter 25 cuts off the excess parts of the pins 12. The bent resistors 11 and the cut-off pins 12 both fall into the first collecting tray 31, and the pins 12 pass through the leakage holes 32 and fall into the second collecting tray 41. The resistors 11 and the pins 12 are directly collected separately without manual sorting, thereby improving production efficiency.
