[0024] Further, the material pressing mechanism 4 is a retaining pressing block 1007 in an inverted L shape. The top surface of the retaining pressing block 1007 is matched with the material flow channel 2. The lower end of the retaining pressing block 1007 is provided with a compression spring 1008. The compression spring 1008 is drivingly connected to the power mechanism 3.

[0025] Further, the cutting mechanism 5 is composed of a tool shank 1009 and a cutting block 1010 arranged horizontally on the top surface of the tool shank 1009. The lower end of the tool shank 1009 is connected to the power mechanism 3. The cutting block 1010 is arranged at a position staggered and tangent to the blade block 1006.

[0029] Furthermore, the blade of the blade block 1006 is interleaved with the cutting mechanism 5.

[0030] Furthermore, the top of the material pressing mechanism 4 is aligned with the blade of the cutting block 1006 to achieve the clamping and cutting action of the material.

[0031] The power mechanism 3 can be a lifting cylinder.

[0032] like Figure 4 The diagram shows a specific scheme for the automated cutting of a whole roll of solder strip by the solder strip cutting device and the feeding mechanism of this application.

[0033] The feeding mechanism is integrated on the vertically arranged back plate 101. The main components of the feeding mechanism include a material tray 102, a tensioning roller group 103, and a width adjustment mechanism 104. The material tray 102 is rotated by a brushless motor 105 mounted on the back plate 101 via a gear transmission belt.

[0034] The tensioning roller assembly 103 consists of a floating roller 107 with a counterweight mounted on a vertical rail 106 and a guide roller 108 positioned in the downstream direction, as follows: Figure 4 The components are arranged in a manner shown in the figure. The floating roller 107 integrates a sensor 109. Each sensor 109 is matched with an individual photoelectric switch. The photoelectric switches are distributed at key points 110 along the linear guide 106 on the back plate 101. The photoelectric switches are used to send trigger signals to an external industrial control computer to realize the sensing of the remaining amount of solder strip.

[0035] The width adjustment mechanism 104 is used to adapt to solder strip materials of different widths to prevent the solder strip from deviating or skewing during the feeding stage.

[0036] Before the tin strip reaches the solder lug cutting device of the present application, the embodiment has a feeding mechanism 111 for controlling the cutting length and working rhythm of the tin strip, the main components of the feeding mechanism 111 include a screw slide 112, an end head pressing block 113, a tension pressing wheel 114, etc.

[0037] The screw slide 112 drives a bottom plate 116 to translate under the traction of a belt by a servo motor 115, the bottom plate 116, the width adjusting mechanism 104 and the material flow channel 26 are at the same horizontal height in the embodiment;

[0038] The end head pressing block 113 is arranged on the bottom plate 116 in the figure, and is driven by a cylinder 117 to ascend and descend along the vertical direction, the cylinder 117 is hung on the back side of the bottom plate 116 in the figure, before cutting the tin strip, the end head pressing block 113 is in the pressed state, and after the cutting action is completed, the end head pressing block 113 floats up to remove the material;

[0039] The tension pressing wheel 114 is located on the upstream side of the end head pressing block 113, and is used for pressing the upstream tin strip in cooperation with the end head pressing block 113 in the floating state;

[0040] The bottom plate 116 is connected by the extension plate 118 on the screw slide 112, the extension plate 118 is provided with a horizontal arranged sensing strip 119 for controlling the cutting length, the sensing strip 119 is in the shape of n, the two sides of the sensing strip 119 can be sensed by a photoelectric switch, and different lengths of the sensing strip 119 can be configured to cut the tin strip with different lengths, so that the cutting length of the tin strip can be controlled;

[0041] The tin strip finally reaches the material flow channel 2 of the solder lug cutting device of the present application, the material flow channel 2 is a flat horizontal channel, when the sensing strip 119 cooperates with the photoelectric switch to trigger the detection signal, the power mechanism 3 drives the retaining pressing block 1007 to lift up, the retaining pressing block 1007 is limited by the horizontal height of the first limiting side window 1014 on one hand, and is affected by the compression spring 1008 on the other hand, so as to apply pressure to the tin strip in the material flow channel 2 and top the tin strip on the bottom surface of the template 1004; on the other hand, the power mechanism 3 drives the cutter handle 1009 to ascend, the blade block 1006 at the top end of the cutter handle 1009 contacts the tin strip to continue to ascend, and the tin strip is cut off under the cooperation of the cutting block 1010;

[0042] The cutting components such as the cutting block 1010 are all integrated below the template 1004 in the present application, the cut tin strip is placed flat on the cutting block 1010, so that the downstream equipment can take the material conveniently, and the downstream equipment does not need to integrate the positioning and calibration mechanism such as visual sensor to implement secondary positioning of the cut tin strip.
