[0033] The technical solutions of the embodiments of the present application are briefly described below:

[0034] In the large-scale lamp assembly process, the conveying of parts is an essential link, and the traditional manual handling is low in efficiency.

[0035] In order to improve the efficiency of lamp assembly, according to some embodiments, the present application provides a material conveying equipment, as shown in Figure 1 、 Figure 4 The material conveying equipment comprises:

[0036] A first conveying device 1 is provided with a first conveying belt 2 in the middle, and a first limiting frame 3 and a second limiting frame 4 are arranged on both sides of the first conveying belt 2.

[0037] A baffle 5 is arranged outside the conveying end of the first conveying belt 2, a conveying outlet 6 is formed in the first limiting frame 3 on the inner side of the baffle 5, and a blowing hole 7 is formed in the inner side of the second limiting frame 4 opposite to the conveying outlet 6.

[0038] A conveying channel 8 is communicated with the conveying outlet 6, and the outlet of the conveying channel 8 conveys the material to the next process.

[0039] A material frame 9 is arranged at the upper end of the conveying initial segment of the first conveying belt 2, and a gap for conveying material is formed.

[0040] The working principle of the above embodiment is as follows: Figure 4As shown, the lamp housing 26 is placed in the material box 9, the material conveying equipment is started, and the lamp housing 26 is conveyed from the initial conveying section of the first conveyor belt 2 to the final conveying section of the first conveyor belt 2. High-pressure gas is blown out of the air blowing hole 7 to blow the lamp housing 26 to the entrance of the conveying channel 8, and then the lamp housing 26 is conveyed to the next process through the exit of the conveying channel 8.

[0041] The material conveying equipment of this application can automatically and neatly arrange the lamp housings 26 and convey them to the next process, effectively improving production efficiency, reducing labor intensity, and ensuring the continuity and stability of the production line.

[0042] The following is in conjunction with the appendix to this instruction manual. Figures 1 to 5 The preferred embodiments of this disclosure will be further described in detail below.

[0043] According to some embodiments, such as Figure 1 , Figure 4 As shown, the notch is opened on the side wall of the material frame 9 and extends to the bottom of the material frame 9.

[0044] The working principle of the above embodiment is as follows: the notch serves as the outlet of the material frame 9. After the lamp housing 26 is placed into the material frame 9, it travels along the initial section of the first conveyor belt 2. After the material conveying equipment is started, the lamp housing 26 is conveyed through the side wall of the material frame 9 to the final section of the first conveyor belt 2. Then, high-pressure gas is blown out of the air blowing hole 7, which blows the lamp housing 26 to the entrance of the conveying channel 8. Finally, the lamp housing 26 is conveyed to the next process through the outlet of the conveying channel 8.

[0045] According to some embodiments, such as Figure 1 , Figure 4 As shown, the initial conveying section of the first conveyor belt 2 is a horizontal conveying section 10, the middle conveying section of the first conveyor belt 2 is an arc-shaped conveying section 11, and the final conveying section of the first conveyor belt 2 is a vertical conveying section 12. The arc-shaped conveying section 11 connects the horizontal conveying section 10 and the vertical conveying section 12 respectively.

[0046] The bottom of the material frame 9 is attached to the first limiting frame 3 and the second limiting frame 4 at both ends of the horizontal conveying section 10. The side wall of the material frame 9 is attached to the first limiting frame 3 and the second limiting frame 4 at both ends of the vertical conveying section 12. The notch is opened on the side wall of the material frame 9 corresponding to the vertical conveying section 12 and extends to the bottom of the material frame 9.

[0047] Furthermore, such as Figure 1 , Figure 3 As shown, multiple support rods 19 are evenly spaced on the upper surface of the first conveyor belt 2.

[0048] The working principle of the above embodiments is as follows: Figure 5As shown, the lamp housing 26 is annular, and the bottom of the lamp housing 26 is upwardly convex, and when the lamp is assembled, the bottom of the lamp housing 26 is inside the lamp, and the top of the lamp housing 26 is outside the lamp. Therefore, when the lamp housing 26 is conveyed to the vertical conveying section 12, if the outside of the lamp housing 26 faces the outside of the first conveying belt 2, the lamp housing 26 will fall back into the material frame 9 due to gravity; if the outside of the lamp housing 26 faces the first conveying belt 2, the lamp housing 26 will lean on the first conveying belt 2 due to gravity.

[0049] Further, in order to enable the lamp housing 26 to stably lean on the first conveying belt 2, in some preferred embodiments, the support rod 19 is inclined to the conveying direction, that is, upwardly inclined, and the inclination angle needs to be very small, and needs to ensure that the lamp housing 26 can fall back into the material frame 9 when the outside of the lamp housing 26 faces outward, and the inclination angle value can be set according to actual needs.

[0050] Further, as shown in Figure 1 , Figure 4 , the conveying channel 8 includes a first channel 20, a second channel 21, and an arc-shaped slide 22, the inlet of the first channel 20 is communicated with the conveying outlet 6, the outlet of the first channel 20 is downwardly inclined and communicated with the inlet of the second channel 21, the outlet of the second channel 21 is connected with the inlet of the arc-shaped slide 22, and the outlet of the arc-shaped slide 22 is curved to the direction of material overturning.

[0051] Specifically, as shown in Figure 4 , when the lamp housing 26 leans on the first conveying belt 2 due to gravity, the inside of the lamp housing 26 faces the front side of the first conveying belt 2, and the lamp housing 26 is blown by high-pressure gas to the first channel 20 through the conveying end section of the first conveying belt 2, and then conveyed to the second channel 21, the second channel 21 is vertically arranged, the outlet of the arc-shaped slide 22 is curved to the rear side of the first conveying belt 2, so that the lamp housing 26 can be rotated by 90 degrees, and then the outside of the lamp housing 26 faces upward. The entire overturning process of the lamp housing 26 can be completed during conveying by the conveying device, without the need for a mechanical arm or overturning mechanism at the end of the conveying device to overturn, which greatly saves the cost of lamp production and manufacturing.

[0052] Further, as shown in Figure 1 , Figure 4 , the inlet of the first channel 20 is wider than the outlet of the first channel 20. In order to facilitate the lamp housing 26 to be sorted into the inlet of the first channel 20 in an orderly manner.

[0053] According to some embodiments, as shown in Figures 1 to 2As shown, the material conveying device further comprises a second conveying device 13, an inner side of the second conveying device 13 is provided with a second conveying belt 14, an inlet of the second conveying device 13 is connected to an outlet of the conveying channel 8, that is, an outlet of the arc-shaped chute 22, and an outlet of the second conveying device 13 conveys the material to a next process.

[0054] Specifically, in some embodiments of the present application, the lamp shell 26 is sucked by a suction type mechanical claw at the outlet of the second conveying device 13 and then conveyed to a next process.

[0055] According to some embodiments, as shown in Figure 1 , Figure 4 As shown, the material conveying device further comprises a first sensor 15 arranged at the inlet of the second conveying device 13 and a control system connected to the first sensor 15 and the control motor of the first conveying belt 2 respectively.

[0056] The control system controls the operation of the control motor of the first conveying belt 2 according to the detection signal of the first sensor 15.

[0057] The working principle of the above embodiments is that, in some embodiments, when the first sensor 15 detects the lamp shell 26 at the inlet of the second conveying device 13 after starting the material conveying device, the control system controls the control motor of the first conveying belt 2 to stop working, and the first conveying belt 2 stops conveying the lamp shell 26 to prevent the lamp shell 26 from being blocked.

[0058] When the first sensor 15 does not detect the lamp shell 26 at the inlet of the second conveying device 13, the control system controls the control motor of the first conveying belt 2 to work, and the first conveying belt 2 conveys the lamp shell 26.

[0059] In other embodiments, as shown in Figure 5 Since the lamp shell 26 is annular, when the first sensor 15 detects the lamp shell 26 at the inlet of the second conveying device 13 and continues for a set time length after starting the material conveying device, the control system controls the control motor of the first conveying belt 2 to stop working, and the first conveying belt 2 stops conveying the lamp shell 26 to prevent the lamp shell 26 from being blocked.

[0060] When the lamp shell 26 passes the entrance of the second conveying device 13, the first sensor 15 detects the annular edge of the lamp shell 26 first, and then detects the annular middle of the lamp shell 26, which is the through hole. When the first sensor 15 detects the annular edge of the lamp shell 26, the first sensor 15 outputs that the lamp shell 26 is detected; when the first sensor 15 detects the annular middle of the lamp shell 26, the first sensor 15 outputs that the lamp shell 26 is not detected. When the first sensor 15 detects the lamp shell 26 for a set time, it indicates that the second conveying belt 14 is full of lamp shells 26 and stays for a set time, and the second conveying belt 14 waits for the suction type mechanical claw to suck the lamp shell 26 to the next process.

[0061] According to some embodiments, as shown in Figures 1 to 2 The material conveying device further comprises a second sensor 16 arranged at the exit of the second conveying device 13, and the control system is connected with the second sensor 16 and the control motor of the second conveying belt 14 respectively.

[0062] The control system controls the operation of the second conveying belt 14 according to the detection signal of the second sensor 16.

[0063] The working principle of the above embodiment is that when the second sensor 16 detects the lamp shell 26 at the exit of the second conveying device 13 after the material conveying device is started, the control system controls the control motor of the second conveying belt 14 to stop working, and the second conveying belt 14 stops conveying the lamp shell 26 to wait for the suction type mechanical claw to suck the lamp shell 26. When the suction type mechanical claw sucks the lamp shell 26 and puts it to the next process, the control system controls the control motor of the second conveying belt 14 to work, and the second conveying belt 14 conveys the lamp shell 26 to the exit of the second conveying device 13. Repeat the work.

[0064] According to some embodiments, as shown in Figures 1 to 2 The material conveying device further comprises a rotating table 17, the control system is connected with a rotating motor for controlling the rotating table 17, the rotating table 17 is arranged at the exit of the second conveying device 13, and the control system detects the marked position 27 of the material through the second sensor 16. When the marked position 27 of the material is not at the target position, the control system controls the material to rotate to the target position through the rotating table 17.

[0065] Further, as shown in Figures 1 to 2 The bottom of the rotating table 17 is provided with a support block 18, the rotating shaft of the rotating motor is connected with the middle of the rotating table 17 through the middle of the support block 18, the rotating table 17 is rotatably connected with the support block 18, and the second sensor 16 is arranged on the support block 18.

[0066] Among them, as shown in Figure 5As shown, the marking position 27 is a through hole opened at the top of the lamp housing 26, and the second sensor 16 is arranged above the marking position 27. Figure 2 As shown, the second sensor 16 is an inductive probe.

[0067] The working principle of the above embodiment is that when the lamp housing 26 is conveyed to the outlet of the second conveying device 13, if the marking position 27 is not directly above the second sensor 16, the control system controls the rotating table 17 to rotate the marking position 27 of the lamp housing 26 to be directly above the second sensor 16. After the marking position 27 is directly above the second sensor 16, the suction cup type mechanical claw sucks the lamp housing 26 to the next process.

[0068] The present application can automatically align the lamp housing 26 through the design of the second sensor 16 and the rotating table 17, and the suction cup type mechanical claw can align the buckle for clamping after sucking the lamp housing 26 to the next process.

[0069] According to some embodiments, as shown in Figure 1 , Figure 4 As shown, the material conveying device further comprises a first supporting table 23 arranged at the bottom of the first conveying device 1, for supporting the first conveying device 1.
