Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0032] like Figures 1 to 4 As shown, a TEC lead bending and cutting device provided by the utility model comprises: a base 1 and a lead fixing component, a bending and clamping component, a cutting component and a power system installed relative to the base 1;

[0033] The lead fixing assembly is used to fix the TEC3 to be bent and cut according to the preset position and angle;

[0034] The bending mold clamping component can move relative to the lead fixing component under the driving action of the power system. During the mold clamping process, the bending mold clamping component can drive the TEC lead to be introduced into the guide groove provided on the bending mold clamping component for bending, so that the TEC lead can be extruded into a preset shape corresponding to the guide groove;

[0035] After the TEC lead is bent into a preset shape, the cutting component moves relative to the bending and clamping component under the driving action of the power system, and the cutting component can cut the TEC lead at a preset position.

[0036] In this embodiment, through the mutual cooperation of the lead fixing component, the bending and clamping component, the cutting component and the power system, the lead fixing component is used to fix TEC3, the bending and clamping component is used to bend the TEC lead into a preset shape, and the cutting component is used to cut the TEC lead at a preset position, thereby realizing automated bending and cutting, which can not only ensure the consistency of the bending and cutting shapes, but also greatly improve the production efficiency, meet the production rhythm requirements, unify the bending shape, improve the cutting effect, reduce the TEC lead shedding, breakage and burr phenomenon, and reduce labor costs and time costs.

[0037] Specifically, the power system provides power to close the bending and clamping parts to bend the TEC leads into shape, and then the cutting component cuts the excess TEC leads to a suitable length. Preferably, the power system uses a 12-cylinder compact cylinder to provide bending and cutting power.

[0038] In the above embodiment, preferably, the lead fixing assembly includes a fixing plate 2, a TEC fixing block 10 and a pin fixing block 8, the fixing plate 2 is vertically fixed on the base 1, the TEC fixing block 10 is fixed on the fixing plate 2, the TEC 3 is fixed on the TEC fixing block 10, and the TEC lead is fixed by the pin fixing block 8.

[0039] In this embodiment, when the TEC 3 is manually installed, the TEC 3 is placed in the hole of the TEC fixing block 10 , and at the same time, the TEC lead is fixed in the pin fixing block 8 .

The lower pin bending plate is installed on the pin bending guide rail 7, and can make reciprocating linear motion along the pin bending guide rail 7 under the drive of the pin bending cylinder 14 and the mold closing cylinder 16. The mold closing cylinder 16 is powered by the power system. The lower pin bending plate can move along the pin bending guide rail 7 under the drive of the mold closing cylinder 16, and at the same time pushes the TEC lead into the Z-shaped guide groove to undergo the first bending deformation, and undergoes a second bending deformation relative to the upper pin bending plate 5 during the continued pushing process.

According to the relative position relationship and mutual extrusion and clamping action of the upper pin bending plate 5, the lower pin bending plate and the pin pressing plate 4 at the back, the TEC lead is bent and deformed under pressure. The Z-shaped guide groove serves to naturally implant the TEC lead into the Z-shaped guide groove when the TEC lead is compressed. The Z-shaped guide groove satisfies the requirement of naturally introducing the TEC lead, and will not cause the lead to break due to external pressure. When the TEC lead is deformed for the first time, the TEC lead is squeezed into the Z-shaped guide groove of the lower pin bending plate, and then the upper pin bending plate 5 is driven downward by the cylinder to fix the first bending deformation of the TEC lead and transfer the pressure at the lead bending point to the Z-shaped guide groove of the lower pin bending plate, ensuring that the root of the lead is not subjected to the pressure of the bending mechanism during bending and ensuring that the lead solder joint is not broken.
