[0050] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] The solder sheet production and cutting device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0052] like Figure 1 、 Figure 2 and Figure 3 As shown, a solder sheet production cutting device is characterized by comprising:

[0053] Two symmetrically arranged reciprocating drive mechanisms 100, such as Figure 4 As shown, each reciprocating drive mechanism 100 includes:

[0054] Main driving wheel 101;

[0055] The first driven wheel 102 is connected to the rotating shaft of the main driving wheel 101;

[0056] The second driven wheel 103 is meshed with the first driven wheel 102;

[0057] A first connecting rod 104, one end of which is connected to the rotating shaft of the main driving wheel 101, and the other end of which is connected to the rotating shaft of the second driven wheel 103;

[0058] A second connecting rod 105, one end of which is connected to the rotating shaft of the second driven wheel 103;

[0059] The third connecting rod 106 has one end axially connected to the other end of the second connecting rod 105, a rotating shaft is provided in the middle thereof, and a sliding groove 109 is provided at the other end;

[0060] A connecting block 107 is disposed in the sliding groove 109 of the third connecting rod 106;

[0061] The sliding guide rail 108 is connected to the connecting block 107 via a connecting piece 1010;

[0062] The cutting blade 200 is located between the two reciprocating drive mechanisms 100 and is connected to the connecting block 107 and the slider of the sliding guide rail 108 through the connecting member 1010.

[0063] Each reciprocating drive mechanism 100 further includes:

[0064] The rotary shaft of the thumbwheel 1011 is connected to the rotary shaft of the main driving wheel 101 via a transmission belt 1013;

[0065] The groove wheel 1012 is driven to rotate by the dial wheel 1011.

[0066] The solder sheet production cutting device also includes:

[0067] The conveying roller 300 is installed between the two groove wheels 1012 , and its rotation axis is connected to the rotation axis of the groove wheels 1012 .

[0068] The solder sheet production cutting device also includes:

[0069] The workbench 400 is used to fix the two reciprocating drive mechanisms 100 and the cutting blade 200;

[0070] A plurality of bearing seats 500 are used to support the rotating shafts of the main driving wheel 101, the middle portion of the third connecting rod 106, the thumbwheel 1011 and the sheave 1012 respectively;

[0071] The sliding rail 108 is fixed on the workbench 400 .

[0072] The solder sheet production cutting device also includes:

[0073] Two angle steels 600 are symmetrically arranged on the workbench 400 , and the angle steels 600 are perpendicular to the conveying roller 300 .

[0074] like Figure 5 As shown, the solder sheet production cutting device also includes:

[0075] a return spring 700 disposed between the connecting member 1010 and the cutting blade 200;

[0076] The adjusting bolt 800 passes through the connecting piece 1010 , the return spring 700 and the cutting blade 200 in sequence.

[0077] The diameter of the main driving wheel 101 is greater than the diameter of the first driven wheel 102 .

[0078] The length of the second connecting rod 105 is greater than that of the third connecting rod 106 .

[0079] Specifically, first, one end of the solder roll is flattened and placed steadily under the conveying roller 300. At this time, ensure that the extension direction of the solder roll is consistent with the axial direction of the conveying roller 300 to facilitate subsequent stable conveying.

[0080] Next, a motor or other power source is connected to the main drive wheel 101 to start the rotation of the main drive wheel 101; the rotation of the main drive wheel 101 drives the thumb wheel 1011 to rotate synchronously through the transmission belt 1013, and the rotation of the thumb wheel 1011 further drives the groove wheel 1012 to rotate intermittently. The intermittent rotation characteristic of the groove wheel 1012 is connected to the rotation shaft of the conveying roller 300 through its rotating shaft, so that the conveying roller 300 also presents an intermittent rotation state. This intermittent rotation ensures that the solder sheet roll can move forward smoothly and gradually along the workbench 400 until it approaches the position of the cutting knife 200.

[0081] At the same time, the rotation of the main drive wheel 101 drives the first driven wheel 102 to rotate synchronously, and the first driven wheel 102 is rotated by meshing with the second driven wheel 103. One end of the first connecting rod 104 is connected to the rotating shaft of the main drive wheel 101, and the other end is connected to the rotating shaft of the second driven wheel 103. This connection method ensures that the first connecting rod 104 can swing with the rotation of the main drive wheel 101 and the second driven wheel 103.

[0082] One end of the second connecting rod 105 is connected to the rotating shaft of the second driven wheel 103, and the other end is connected to one end of the third connecting rod 106. A rotating shaft is provided in the middle of the third connecting rod 106, which is supported on the workbench 400 through a bearing seat 500 to ensure that it can swing up and down smoothly. A sliding groove 109 is provided at the other end of the third connecting rod 106. A connecting block 107 is arranged in the sliding groove 109 and can slide along the sliding groove 109. The sliding guide rail 108 is connected to the connecting block 107 through a connecting piece 1010, and the cutting knife 200 is connected to the slider of the sliding guide rail 108 through a combination of the connecting piece 1010, a return spring 700 and an adjusting bolt 800.

[0083] When the main driving wheel 101 rotates, through the linkage action of the first driven wheel 102, the second driven wheel 103 and the first connecting rod 104, the second connecting rod 105 and the third connecting rod 106, the third connecting rod 106 drives the connecting block 107 to slide in the slide groove 109, and then drives the sliding guide rail 108 and the cutting knife 200 to move up and down along the track of the sliding guide rail 108. This up and down movement cooperates with the intermittent rotation of the conveying roller 300 to achieve continuous and smooth cutting of the solder sheet roll by the cutting knife 200.

[0084] During the cutting process, the return spring 700 plays a role of buffering and resetting. When the cutting knife 200 cuts downward, the return spring 700 is compressed. When the cutting is completed, the return spring 700 releases energy and pushes the cutting knife 200 to reset upward to prepare for the next cutting. The adjusting bolt 800 is used to adjust the pre-tightening force of the return spring 700, thereby achieving fine-tuning of the cutting force of the cutting knife 200.

[0085] In addition, two symmetrically arranged angle steels 600 are fixed on the workbench 400, which are arranged perpendicular to the conveying roller 300. The presence of the angle steels 600 plays a guiding and supporting role, ensuring that the solder sheet roll can maintain a stable path during the conveying process to avoid deviation or wrinkling.

[0086] To sum up, according to the solder sheet production and cutting device disclosed in the present invention, two symmetrically arranged reciprocating drive mechanisms are used to achieve smooth reciprocating motion of the cutting knife, ensuring the straightness of the cutting path, making the cutting process smoother, and improving the production efficiency and product quality of the solder sheet.

[0087] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
