[0056] In the photodiode turnover technical field, the blister box is generally used to store photodiodes, but generally only the up-down orientation consistency of multiple photodiodes can be ensured, and the circumferential orientation consistency of multiple photodiodes cannot be ensured, that is, the consistency of the pin arrangement state of each photodiode cannot be ensured. Therefore, generally, in the process of photodiodes entering the first automatic production process from the blister box, the photodiode material state needs to be consistent and transferred, so as to facilitate the efficient picking and mounting of photodiodes. However, at present, most optoelectronic enterprises still use manual work to complete the related turnover work, generally using tweezers to clamp the pins of photodiodes, and manually adjusting the angle and loading one by one. The operation process is complicated, the efficiency is low, the labor intensity is large, and the gold plating layer and components on the surface of the photodiode are easily damaged, which affects the processing quality of the photodiode.

[0057] Therefore, the present application provides a photodiode automatic turnover device, which aims to solve the problems of low efficiency and easy damage to photodiodes in the process of manually clamping and adjusting the angle of photodiodes. Figures 1 to 9 The structure schematic diagram of an embodiment of the photodiode automatic turnover device provided by the present application is shown.

[0058] Please refer to Figures 1 to 4The photoelectric diode automatic turnover device 100 comprises a base 1, a movement module 2 and an adjustment module 3, the base 1 is formed with a material taking station 1a and a material placing station 1b, the material taking station 1a is used to provide photoelectric diodes, and the material placing station 1b is used to place the photoelectric diodes at the same angle; the movement module 2 is arranged on the base 1, the movement module 2 comprises a mounting seat 21 capable of moving to the material taking station 1a and the material placing station 1b respectively; and the adjustment module 3 comprises a suction nozzle 31, a visual camera 32 and a driving device 33, which are all arranged on the mounting seat 21, the visual camera 32 is used to take pictures downward to obtain the placement angle information of the photoelectric diodes in the material taking station 1a, the suction nozzle 31 is used to suck the photoelectric diodes and the suction nozzle 31 can rotate along the up-down axis, and the driving device 33 is used to drive the suction nozzle 31 to rotate correspondingly according to the placement angle information.

[0059] In the technical scheme, the mounting seat 21 can move between the material taking station 1a and the material placing station 1b, thereby driving the suction nozzle 31 to suck the photoelectric diodes in the material taking station 1a to the material placing station 1b, and in addition, before the suction nozzle 31 sucks the photoelectric diodes, the visual camera 32 arranged on the mounting seat 21 can take pictures to obtain the placement angle information of the photoelectric diodes, so that the control system can automatically calculate the angle at which the photoelectric diodes need to be adjusted, thereby driving the suction nozzle 31 to rotate by the driving device 33 when the suction nozzle 31 sucks the photoelectric diodes, so that the photoelectric diodes can be placed on the material placing station 1b at the same angle, thereby making the material taking state of the plurality of photoelectric diodes consistent, so as to facilitate efficient picking and mounting of the photoelectric diodes subsequently, the automatic adjustment process replaces the manual operation mode, greatly improves the adjustment efficiency, reduces the labor intensity, and at the same time, the photoelectric diodes are not damaged due to human factors, and the processing quality of the photoelectric diodes is ensured.

[0060] In the transfer process of the suction box 300, it is difficult to ensure that the pins of the photoelectric diodes are not bent due to collision, in order to ensure that the suction nozzle 31 can accurately place the photoelectric diodes on the material placing station 1b, please refer to Figure 3 and Figure 4In the embodiment, the movement module 2 comprises a moving base 22 capable of moving in a horizontal plane, and the mounting base 21 is movably arranged on the moving base 22 in the up-down direction. The photoelectric diode automatic turnover device 100 further comprises a pin shaping structure 4 arranged on the moving base 22 and capable of selectively blocking and giving way to the suction nozzle 31. The pin shaping structure 4 is formed with a shaping groove 42 opening upward, and the cross section of the shaping groove 42 gradually increases in the direction from bottom to top. When the pin shaping structure 4 blocks the suction nozzle 31, the shaping groove 42 is arranged opposite to the suction nozzle 31 to allow the pins of the photoelectric diode to correspondingly extend into. When the pin shaping structure 4 gives way to the suction nozzle 31, the suction nozzle 31 can continue to move downward. Since the cross section of the shaping groove 42 gradually increases from bottom to top, and the shaping groove 42 is arranged opposite to the suction nozzle 31 when the pin shaping structure 4 blocks the suction nozzle 31, in the process of the suction nozzle 31 sucking the photoelectric diode downward, the pins of the photoelectric diode can be gathered and shaped under the guidance of the groove wall of the shaping groove 42, thereby preventing the pins of the photoelectric diode from turning outward and being unable to be placed into the material placing station 1b. Furthermore, after the pins of the photoelectric diode are shaped, the pin shaping structure 4 can selectively give way to the suction nozzle 31, so that the suction nozzle 31 can continue to move downward to place the photoelectric diode.

[0061] It should be noted that the pin shaping structure 4 can selectively block and give way to the suction nozzle 31, and various structural forms can be used. In a specific embodiment, the pin shaping structure 4 comprises a mounting seat and a movable plate. The mounting seat is arranged on the moving base 22, and the movable plate is swingably arranged on the mounting seat along the horizontal direction to have a horizontal position blocking the suction nozzle 31 and a vertical position giving way to the suction nozzle 31. The shaping groove 42 is arranged on the movable plate to be aligned with the suction nozzle 31 when the movable plate is in the horizontal position, thereby playing a shaping role on the photoelectric diode. Since the movable plate swings downward to the vertical position, the shaping groove 42 will not damage the pins of the photoelectric diode.

[0062] In another embodiment, the pin shaping structure 4 comprises a toggle finger air cylinder 41, which has two shaping clamping jaws 411 below the suction nozzle 31 and rotatable along the axis in the up-down direction, to have a blocking position of mutual embracing to block the suction nozzle 31, and a position of mutual moving away to give way to the suction nozzle 31, and a shaping half groove 421 is formed on the opposite end face of each of the two shaping clamping jaws 411, and the shaping half groove 421 is provided through upwardly; wherein, when the two shaping clamping jaws 411 are in the blocking position, the two shaping half grooves 421 are combined to form the shaping groove 42, at this time, the downward movement of the suction nozzle 31 is blocked by the shaping clamping jaws 411, so that the pin of the photodiode gradually penetrates into the shaping groove 42, thereby being gradually shaped back to normal, then only the toggle finger air cylinder 41 needs to be controlled to drive the two shaping clamping jaws 411 to loosen, so as to give way to the suction nozzle 31 to continue to move downward, and this form of controlling the rotation of the shaping clamping jaws 411 does not require excessive activity space, and only needs to process the shaping half groove 421 on the shaping clamping jaws 411, so the assembly cost is lower.

[0063] The structure for driving the rotation of the suction nozzle 31 has various forms, and specifically, please refer to Figure 3 In the embodiment, the driving device 33 comprises a driving motor 331, a driving pulley 332 and a driven pulley 333, the driving motor 331 is arranged on the mounting seat 21, the driving motor 331 has an output shaft rotatable along the axis in the up-down direction; the driving pulley 332 is coaxially arranged on the output shaft; and the driven pulley 333 is coaxially arranged on the suction nozzle 31, and the driven pulley 333 is connected to the driving pulley 332 through a transmission belt. In this way, in the process of driving the rotation of the suction nozzle 31, the driving motor 331 first drives the rotation of the driving pulley 332, and then the driving pulley 332 drives the rotation of the driven pulley 333, thereby driving the rotation of the suction nozzle 31, and the form of belt transmission is stable in driving, low in cost and good in practicability.

[0064] In other embodiments, the driving device 33 can also be composed of a driving motor 331 and a gear transmission mechanism, and the specific structure is not described herein.

In the technical scheme provided by the embodiment, the discharging frame 81 contains a plurality of material carrying plates 812 through a plurality of material carrying cavities 811, and the discharging frame 81 can move in the third direction, so that the corresponding material carrying cavity 811 can be aligned to the material placing chute 71, that is, the second pushing structure 82 can push the empty material carrying plate 812 in the material carrying cavity 811 to move to the material placing seat 7, thereby providing the material placing station 1b with the material carrying plate 812; after the material carrying plate 812 is filled with photoelectric diodes, the second pushing structure 82 can reversely push the material carrying plate 812 back into the material carrying cavity 811, after the discharging frame 81 moves in the third direction to align another layer of material carrying cavities 811 to the material placing chute 71, the second pushing structure 82 repeatedly performs the above operation, thereby automatically providing the material taking station 1a with the material carrying plate 812 and recovering the full material carrying plate 812 into the discharging frame 81, replacing manual discharging, greatly improving the automation degree of the device.

[0069] Further, in the embodiment, the material placing chute 71 can form a discharging channel with the corresponding material carrying cavity 811; the second pushing structure 82 comprises two second push rod cylinders 821 arranged at two ends of the discharging channel respectively, each second push rod cylinder 821 has a cylinder top rod capable of extending into the discharging channel in the second direction, and the two cylinder top rods cooperate to push the material carrying plate 812 to switch positions in the discharging channel.
