Therefore, they cannot be understood as a limitation on the present invention.

[0045] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] Example:

[0049] like Figure 1 As shown, an embodiment of the present application discloses an electronic component pin cutting device, which is used to cut the pins of electronic components in the form of a single in-line package (SIP). Its specific structure includes: a base plate 1, two side plates 2, a top plate 3, a drive cylinder 4, a drive plate 5, a cutting knife 6, a support plate 7, a pressure plate 8, multiple guide rods 9, multiple springs 10 and a pad 1A.

[0050] The bottom plate 1 is a convex structure, having a support area 11 and a docking area 12 provided on one side of the support area 11, and a discharge port 121 is provided on the top surface of the docking area 12; Figure 5As shown, mounting grooves are provided on the left and right sides of the support area 11 for fixing to the machine platform via bolt and nut assemblies, so as to facilitate assembly and disassembly of the device.

[0051] The two side panels 2 are vertically mounted on the top surface of the support area 11 and are located on both sides of the docking area 12; the side panels 2 extend toward the side close to the docking area 12, and a passage opening is left on the bottom surface for the lateral entry and exit of materials, thereby improving the stability of the structure.

[0052] The top plate 3 is laterally mounted on the top of the two side plates 2; the top plate 3 is preferably connected by bolts to facilitate production and assembly.

[0053] The driving cylinder 4 has a piston rod 41 and a cylinder body 42. The piston rod 41 is set downward, and the cylinder body 42 is installed on the bottom surface of the top plate 3 and is located between the two side plates 2. It is preferably connected by bolts to facilitate production and assembly.

[0054] The driving plate 5 is laterally mounted on the bottom end of the piston rod 41 to drive the cutting blade 6 to move up and down.

[0055] The cutting knife 6 is installed on the bottom surface of the driving plate 5 and corresponds to the discharge port 121; the bottom surface of the driving plate 5 is provided with a slot that is interference fit with the cutting knife 6 to complete the connection between the two, but it is not limited to this, and other connection forms can also be used, such as bolt connection, snap connection, etc., without specific limitation.

[0056] The support plate 7 is movably mounted on the piston rod 41 and can move up and down relative to the piston rod 41 .

[0057] The pressing plate 8 is arranged below the driving plate 5 , and a first through slot 81 adapted to the cutting blade 6 is provided on the top surface thereof; the pressing plate 8 is used to press the pins, and the first through slot 81 is used for the cutting blade 6 to pass through.

[0058] A plurality of guide rods 9 are vertically mounted on the pressure plate 8 , and the top ends thereof pass through the driving plate 5 and are connected to the support plate 7 .

[0059] A plurality of springs 10 are sleeved on the guide rods 9 in a one-to-one correspondence and supported between the driving plate 5 and the pressure plate 8 .

[0060] The pad 1A is installed on the top surface of the docking area 12, and the top surface of the pad 1A is provided with a second through groove 1A1 adapted to the cutting knife 6; the pad 1A is detachably connected to the docking area 12, which is convenient for later maintenance and replacement, reducing the maintenance cost of the device.

[0061] During installation, the device is installed on the machine, and then the two sides of the docking area 12 are docked with the conveying device, so that the electronic components are transported by the conveying device. Figure 3 As shown, the pins can be swept horizontally from the top surface of the pad 1A, and the excessively long portion can pass over the second through slot 1A1.

[0062] During cutting, the conveying device drives the electronic components to move horizontally. When the electronic components move to the point where the excessively long part of the pin is located above the second through slot 1A1, the driving cylinder 4 is started, and the piston rod 41 extends downward, driving the driving plate 5 to move downward, thereby driving the support plate 7, the pressure plate 8 and the guide rod 9 to move downward together; when the pressure plate 8 presses on the pin, the driving plate 5 overcomes the tension of the spring 10 and continues to move downward along the guide rod 9. At this time, the pressure plate 8 firmly presses the pin due to the force generated by the compression of the spring 10; at the same time, the cutting knife 6 extends downward from the first through slot 81 under the drive of the driving plate 5, and extends into the second through slot 1A1, thereby cutting off the excessively long pin, and the waste generated by the cutting falls into the material guide device installed under the frame through the second through slot 1A1 and the discharge port 121, and finally falls into the collection device under the guidance of the material guide device; after the cutting is completed, the piston rod 41 retracts upward to its original position.

[0063] The utility model uses the pressure plate 8 and the spring 10 to compress and fix the pins before cutting, thereby improving the cutting effect and forming a closed chamber to prevent waste from splashing during the cutting process. The second through groove 1A1 and the discharge port 121 are also used to guide and collect the waste, ensuring the cleanliness of the cutting table, improving the production yield, and facilitating cleaning and maintenance.

[0064] In some embodiments, as Figures 2 and 3 As shown, in order to facilitate disassembly and assembly, a first threaded hole 51 is opened on the top surface of the driving plate 5, and the bottom end of the piston rod 41 is threadedly connected to the first threaded hole 51, thereby facilitating assembly and improving production efficiency.

[0065] Preferably, a limiting through hole 71 adapted to the piston rod 41 is provided on the top surface of the support plate 7 , so that the support plate 7 can slide up and down along the piston rod 41 , thereby improving the smoothness of movement.

[0066] In some embodiments, as Figures 2 to 4 As shown, the driving plate 5 , the supporting plate 7 and the pressing plate 8 are all rectangular structures, and the two sides are in contact with the two side plates 2 .

[0067] Through the above arrangement, the two side plates 2 can limit and guide the driving plate 5, the support plate 7 and the pressure plate 8, thereby improving the structural stability and the smoothness of movement.

[0068] For example, there are four guide rods 9, arranged at the four corners of the top surface of the pressure plate 8, to reduce stress concentration and prevent jamming or locking during relative movement between the drive plate 5 and the guide rods 9, thereby improving movement smoothness. However, this is not a limitation; the number can also be six or other, and there is no specific limitation.

[0069] In some embodiments, as Figure 3 As shown, the pad 1A is covered on the top surface of the support area 11 , and its two ends are in contact with the two side panels 2 .

[0070] The above arrangement serves to limit the pad 1A, facilitates the installation and removal of the pad 1A, and can fully support the pressing plate 8, thereby reducing stress concentration and ensuring the pressing effect on the pins.

[0071] In some embodiments, as Figure 2 As shown, in order to facilitate disassembly and assembly, the top surface of the pad 1A is provided with multiple stepped through holes 1A2, and countersunk bolts 1B are inserted into the stepped through holes 1A2; the top surface of the docking area 12 is provided with second threaded holes 122 corresponding one-to-one to the stepped through holes 1A2, and the countersunk bolts 1B are threadedly connected to the second threaded holes 122.

[0072] It can be understood that the countersunk bolt 1B can be sunk and inserted into the stepped through hole 1A2, thereby avoiding interference with the fit between the pressure plate 8 and the backing plate 1A.

[0073] The above arrangement facilitates the disassembly and assembly of the backing plate 1A, facilitates production assembly and subsequent maintenance, improves production efficiency, and reduces maintenance costs.

[0074] In some embodiments, as Figure 6 and Figure 7 As shown, a limit block 1C is provided at the bottom end of the guide rod 9; a first through hole 82 corresponding one-to-one to the guide rod 9 is provided on the top surface of the pressure plate 8, and an embedding groove 83 corresponding one-to-one to the limit block 1C is provided on the bottom surface of the pressure plate 8.

[0075] Specifically, the guide rod 9 is inserted into the first through hole 82, and the limit block 1C is sunken into the embedding groove 83, thereby avoiding interference with the fit between the pressure plate 8 and the pad 1A.

[0076] Through the above arrangement, the guide rod 9 and the pressing plate 8 are detachably connected and fixed, and play a positioning role, which facilitates production and assembly and improves disassembly and assembly efficiency.

[0077] In some embodiments, as Figure 7 As shown, the top surface of the driving plate 5 is provided with a second through hole 52 corresponding one-to-one to the guide rod 9, and the bottom surface of the driving plate 5 is provided with a mounting groove 53 corresponding one-to-one to the spring 10.

[0078] Specifically, the guide rod 9 is inserted into the second through hole 52, which plays a role of radial limitation and ensures the stability of the support plate 7, the pressure plate 8 and the guide rod 9; the mounting groove 53 is used to accommodate the spring 10 to prevent it from being over-compressed and extend its service life.

[0079] In some embodiments, as Figure 6 and Figure 7 As shown, the bottom surface of the support plate 7 is provided with third through holes 72 corresponding to the guide rods 9 one by one, and the top end of the guide rod 9 passes through the third through hole 72 and is threadedly connected to the limiting sleeve 1D.

[0080] Specifically, the limiting cover 1D is sleeved on the top of the third through hole 72 to limit the guide rod 9 from being separated from the third through hole 72. It can be tightened or loosened by rotating, which is convenient for installation and disassembly.

[0081] Through the above arrangement, the guide rod 9 and the support plate 7 are detachably connected and fixed, and a positioning function is played, which also facilitates production and assembly and improves disassembly and assembly efficiency.

[0082] Based on the above embodiment, Figure 7 As shown, the top surface of the support plate 7 is provided with a positioning groove 73 corresponding to the limiting cover 1D; the limiting cover 1D is partially inserted into the positioning groove 73, thereby improving the structural compactness of the device.

However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
