[0025] A control panel 32 is installed on the top side of the main board 1. An indicator light 31 is installed on the top side of the main board 1. The control panel 32 is electrically connected to the electrode 10, the electric chip 13 and the indicator light 31. The control panel 32 is used for signal transmission between the electrode 10 and the electric chip 13, and for controlling the indicator light 31.

[0026] The distance between the arc clamping plate 7 and the arc surface of the diode is equal to the distance between the electrode 10 and the electric sheet 13; during operation, when the diode is glued, it is often necessary to use a positioning clamping component to clamp and fix it, but in the prior art, the clamping force of the diode cannot be controlled, which will lead to excessive clamping and damage to the diode, thereby affecting the processing quality of the diode. The two ends of the diode are respectively placed in the interior of the fixing sleeves 2 at the two ends of the main board 1, and according to the distance between the arc clamping plate 7 and the arc surface of the diode, the fixing of the limit ring 8 is released by the locking screw 9, and the scale line 1 is fixed. 2, the limiting ring 8 drives the sliding of the electrode 10 on the guide rod 5. After adjusting the distance between the arc clamping plate 7 and the arc surface of the diode to be equal to the distance between the electrode 10 and the electric sheet 13, the limiting ring 8 is fixed, and the arc clamping plate 7 and the electrode 10 are driven to move downward by rotating the handle 4 with the cooperation of the guide rod 5. After the electrode 10 contacts the electric sheet 13 on the limiting rod 11, the control panel 32 turns on the indicator light 31 to remind the operator that the diode has been positioned and clamped. The present invention realizes the rapid positioning and clamping of the diode, and can control the clamping force to avoid excessive clamping.

[0027] Furthermore, a driving motor 14 is installed on one side of the main board 1, and a cavity 15 is provided inside the main board 1. The output end of the driving motor 14 is rotatably connected to a bidirectional screw rod 16, and one end of the bidirectional screw rod 16 passes through the cavity 15 and is rotatably installed on its inner wall. Two sliding grooves 17 are symmetrically provided inside the two ends of the cavity 15, and sliders 18 are slidably installed inside the sliding grooves 17.

A support plate 22 is fixedly connected to the top side of the supporting block 20 through the limiting groove 21, and the support plate 22 is fixedly connected to the bottom arc surface of the fixing sleeve 2. During operation, since the diodes are of different lengths, the positioning clamping assembly needs to be adjusted when processing them. According to the length of the diodes, the driving motor 14 is started to drive the rotation of the bidirectional lead screw 16, so that the connecting blocks 19 and the slider 18 at both ends move along the slide groove 17. The movement of the connecting block 19 drives the movement of the supporting block 20. The supporting block 20 can drive the positioning clamping assembly to slide along the limiting groove 21, shortening or increasing the distance between the two positioning clamping assemblies, so that the positioning clamping assembly can move stably, thereby realizing the processing of diodes of different lengths.

In the production and processing of diodes, the diodes need to be glued. When glueing, the diodes often need to be fixed to avoid offset during the glue dispensing process. By judging the position where the diode needs to be glued, loosen the positioning bolt 26, and move the sliding block 25 along the slide rail 24. After moving to the specified position, fix the sliding block 25 by the positioning bolt 26, start the cylinder 27, and the cylinder 27 drives the glue dispensing assembly to move downward, and transports the glue in the glue storage cylinder 29 to the connecting cavity 28, so that the glue dispensing head 30 performs the glue dispensing operation on the diode.

[0030] Working principle: Since the lengths of diodes are different, the positioning clamping assembly needs to be adjusted when processing them. According to the length of the diode, the driving motor 14 is started to drive the rotation of the bidirectional screw rod 16, so that the connecting blocks 19 and the slider 18 at both ends move along the slide groove 17. The movement of the connecting block 19 drives the movement of the supporting block 20, and the supporting block 20 can drive the positioning clamping assembly to slide along the limiting groove 21, shortening or increasing the distance between the two positioning clamping assemblies, so that the positioning clamping assembly can move stably, and realizes the processing of diodes of different lengths;

[0031] When dispensing glue on the diode, it is often necessary to use a positioning clamping component to clamp and fix it. However, in the prior art, the clamping force of the diode cannot be controlled, which will lead to excessive clamping and damage to the diode, thereby affecting the processing quality of the diode. The two ends of the diode are respectively placed in the interior of the fixing sleeves 2 at both ends of the main board 1. According to the distance between the arc clamping plate 7 and the arc surface of the diode, the fixing of the limit ring 8 is released by the locking screw 9. With the cooperation of the scale line 12, the limit ring 8 drives the sliding of the electrode 10 on the guide rod 5. After adjusting the distance between the arc clamping plate 7 and the arc surface of the diode to be equal to the distance between the electrode 10 and the electric sheet 13, the limit ring 8 is fixed. By rotating the handle 4, with the cooperation of the guide rod 5, the arc clamping plate 7 and the electrode 10 are driven to move downward. After the electrode 10 contacts the electric sheet 13 on the limit rod 11, the control panel 32 turns on the indicator light 31 to remind the operator that the diode has been positioned and clamped. The present invention realizes the rapid positioning and clamping of the diode, and can control the clamping force to avoid excessive clamping.

[0032] A diode is an electronic component, mainly made of semiconductor materials, usually used in circuit connections, and has the characteristic of unidirectional conductivity. In the production and processing of diodes, the diodes need to be glued, and when glued, the diodes often need to be fixed to avoid offset during the glue dispensing process. By judging the position where the diode needs to be glued, loosen the positioning bolt 26, and move the sliding block 25 along the slide rail 24. After moving to the specified position, the sliding block 25 is fixed by the positioning bolt 26, and the cylinder 27 is started. The cylinder 27 drives the glue dispensing assembly to move downward, and the glue in the glue storage cylinder 29 is transported to the connecting cavity 28, so that the glue dispensing head 30 performs the glue dispensing operation on the diode.
