Description

Technical Field

[0001] This invention relates to the field of pin assembly equipment technology, specifically to a cutting device and its usage method. Background Technology

[0002] Pin headers are widely used in PCB board connections and are known as universal connectors. They are widely used in electronic products, typically with 40 pins or more per pin header. Pin headers come in various pitches (0.8 / 1.0 / 1.27 / 2.0 / 2.54mm) and are further subdivided into single-row 180°, single-row 90°, single-row SMT, double-row 180°, double-row 90°, and double-row SMT specifications. During production, the pin headers are cut to the required number of pins. Currently, pin header cutting equipment on the market uses a disc-shaped cutter with serrated outer circumference. After use, burrs are generated at the cutting position of the pin header. For plastic burrs, the product needs to be frozen to remove them. The original cutting mechanism uses a high-speed steel saw blade to cut the pin header product by high-speed motor rotation. During the high-speed operation of the motor, the saw blade and the plastic pin header generate cutting friction. The high-speed rotating saw blade easily generates high temperature after friction, causing plastic burrs. After the high temperature, the plastic burrs naturally cool and harden, making subsequent removal difficult. If freezing cannot remove the burrs, manual processing is required. Products with incomplete burr removal will cause adverse effects and product defects during subsequent installation and connection on the PCB board. Summary of the Invention

[0003] The purpose of this invention is to provide a cutting device and its method of use to solve the above-mentioned problems. By replacing the traditional rotating cutting needle hacksaw blade with a straight blade, the problem of plastic burrs generated by the high-temperature friction caused by the high-speed rotation of the hacksaw blade as a cutting tool is solved, reducing the subsequent deburring process and saving manual labor. In addition, cutting grooves and teeth are provided at both ends of the blade, which facilitates the gradual cutting of the wire from both sides inward by multiple sets of teeth. This avoids the problem of the traditional blade jamming and cutting difficulties caused by multiple sets of blades with equal widths around the circumference. The cutting process is smoother, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a cutting device, including a base and a mounting plate. The mounting plate is disposed above the base, and a base frame supporting the mounting plate is fixed on the top side of the base. A vertical cylinder is disposed above the mounting plate, a cylinder bracket is fixed on the top rear side of the mounting plate, a cylinder support for mounting the vertical cylinder is fixed on the top of the cylinder bracket, and a fixing plate is vertically slidably disposed on the front side of the cylinder bracket.

[0006] The front side of the fixed plate is detachably provided with several sets of cutters. The inner sides of the upper and lower ends of the cutters are transversely perforated with cutting grooves. The inner sides of the cutting grooves are symmetrically provided with multiple sets of cutting teeth with the spacing gradually decreasing from the outside to the inside.

[0007] Preferably, the cutter has two sets of slots symmetrically arranged on the rear side, and the front side of the fixing plate is fixed with a locking strip that engages with the inside of the slots. The front side of the fixing plate is densely covered with multiple sets of limiting grooves that accommodate the cutter and are evenly arranged laterally.

[0008] Preferably, both ends of the card strip are provided with longitudinal disassembly holes, and a fixing frame is provided in front of the fixing plate. The fixing frame is a C-shaped frame with the opening facing backward. Both ends of the fixing frame extend to the outside of the two sets of disassembly holes, and both ends of the fixing frame are provided with countersunk holes for bolts to pass through and connect to the disassembly holes. The rear side of the fixing frame is provided with a movable groove that engages and abuts the cutter. Both the movable groove and the limiting groove are comb-shaped structures.

[0009] Preferably, the cylinder bracket has two sets of vertically extending slide rails arranged laterally on the front side, and a linear slider that slides vertically and cooperates with the slide rails is fixed on the rear side of the fixing plate. The bottom telescopic end of the vertical cylinder is connected to a cylinder adapter that supports the fixing plate and drives the cutter to slide vertically to perform the cutting action.

[0010] Preferably, the base frame is fixed to the rear top of the base, the top of the base frame is fixed with a sliding seat that supports the back-and-forth movement of the mounting plate, a longitudinal cylinder is fixed to the rear side of the base frame, the front side of the mounting plate is provided with a receiving groove for accommodating the vertically protruding cutter, the bottom side of the mounting plate is fixed with a sliding block that longitudinally slides with the sliding seat, and the cylinder bracket is fixed to the top side of the mounting plate by bolts.

[0011] Preferably, a lower mold is provided on the top side of the mounting plate, and an upper mold that forms a needle cutting mold is detachably provided above the lower mold. An upper hole and a lower hole are respectively provided between the upper mold and the lower mold to accommodate the needles. A constraint groove is provided on the bottom side of the mounting plate to engage and abut against the sliding seat. A connecting hole is provided on the mounting plate above the constraint groove to allow bolts to pass through and fix the sliding seat.

[0012] Preferably, the base has two sets of positioning brackets on the front top, and the top of the two sets of positioning brackets is fixed with two sets of positioning blocks that extend to the outer sides of the upper mold respectively.

[0013] Preferably, a support plate is horizontally connected between the two sets of positioning brackets, the bottom side of the base frame is fixed to the top of the base, and multiple sets of positioning pins for constraining and positioning the base frame, the support plate, and the positioning brackets are vertically protruding from the top side of the base.

[0014] Preferably, the front telescopic end of the longitudinal cylinder is fixedly connected to the rear side of the sliding block by bolts, and the length of the sliding seat is greater than the longitudinal telescopic stroke of the longitudinal cylinder.

[0015] The method of using the cutting device includes the following steps:

[0016] a. Separate the upper mold from the top side of the lower mold, place the pin header into the top side of the lower mold, and use the upper mold and lower mold to clamp and install the pin header. This allows the upper mold and lower mold to position the pin header product and complete the clamping and positioning of the pin header above the mounting plate.

[0017] b. According to the number of pins to be cut, remove the fixing frame from the front of the fixing plate. Place several sets of cutters into the corresponding limiting grooves on the front of the fixing plate at the required cutting positions on the pins. Then, fasten the fixing frame to the front of the fixing plate, press the slots of the cutters against the locking strips of the fixing plate, and use the movable slots of the fixing frame in conjunction with the limiting grooves of the fixing plate to lock the cutters. This makes it easy to adjust the number and position of the cutters according to the required cutting positions of the pins.

[0018] c. Using the cylinder adapter connected to the bottom telescopic end of the vertical cylinder, push the fixed plate to drive multiple sets of cutters to move down. The fixed plate is guided by the sliding cooperation between the rear linear slider and the slide rail. The fixed plate supports the bottom side of the cutter to move down to the pin clamping position on the top side of the mounting plate. The cutting groove at the end of the cutter is used to position the pins at the corresponding cutting position. Several sets of cutting teeth with gradually decreasing gaps from the outside to the inside of the cutting groove are used to cut the pins to the required number of pins.

[0019] The beneficial effects are as follows: This invention replaces the traditional rotating cutting needle hacksaw blade with a straight cutting blade, and uses the cutting blade to punch the needles, which solves the problem of high temperature generating plastic burrs caused by the high-speed rotation and friction of the hacksaw blade as a cutting tool, reduces the subsequent deburring process, saves manual labor, and reduces labor costs.

[0020] Furthermore, the fixed plate is densely covered with comb-shaped limiting grooves for mounting the cutter, which can adjust the initial position and spacing of multiple sets of cutters according to the needle spacing, thereby completing the multi-position cutting of the needle in one punching process, which helps to improve the mass production speed of industrial products.

[0021] In addition, both ends of the cutter are equipped with cutting grooves and teeth, which makes it easy to replace the cutter when one end becomes dull or damaged. The multiple sets of teeth are designed with a progressive structure with gradually decreasing spacing, which makes it easier to cut the wire from both sides inward by using multiple sets of teeth. This avoids the problem of the traditional cutter having multiple sets of blades with equal width on the circumference, which makes the cutter prone to jamming and difficult to cut. The cutting process is smoother. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] See Figures 1-11 As shown, the present invention provides a cutting device, including a base 1 and a mounting plate 3. The mounting plate 3 is disposed above the base 1, and a base frame 2 supporting the mounting plate 3 is fixed on the top side of the base 1. A vertical cylinder 8 is disposed above the mounting plate 3. A cylinder bracket 4 is fixed on the top rear side of the mounting plate 3. A cylinder support 7 for mounting the vertical cylinder 8 is fixed on the top of the cylinder bracket 4. A fixed plate 5 is vertically slidably disposed on the front side of the cylinder bracket 4. The vertical cylinder 8 is used to support the fixed plate 5 to move up and down.

[0038] Several sets of cutters 6 are detachably mounted on the front side of the fixing plate 5. The inner sides of the upper and lower ends of the cutter 6 are transversely perforated with cutting grooves 601. The inner sides of the cutting grooves 601 are symmetrically arranged with multiple sets of blades 602 with gradually decreasing spacing from the outside to the inside. The inner edge of the blades 602 is a blade structure, so that the multiple sets of blades 602 form a serrated progressive cutting structure. When the cutter 6 supported by the fixing plate 5 cuts the pin 10 up and down, it improves the high temperature problem caused by the existing circular steel saw blade, avoids the generation of plastic burrs at the cutting position of the pin 10, and cuts the pin 10 from both sides to the middle through the progressive multiple sets of blades 602, so as to reduce the processing difficulty. Specifically, the traditional cutter 6 has only one set of blades. In the process of cutting the pin 10, the traditional cutter 6 needs to completely cut the pin 10 in one go, which is inconvenient to operate and can be used for cutting thicker pins 10.

[0039] As an optional implementation, two sets of slots 603 are symmetrically arranged on the rear side of the cutter 6. A retaining strip 502 is fixed to the front side of the fixing plate 5, which engages with the inner side of the slots 603. The retaining strip 502 works with the slots 603 to vertically position the cutter 6, ensuring that the fixing plate 5 can support and carry multiple sets of cutters 6 to move up and down synchronously to achieve the punching action. In addition, the two sets of slots 603 are vertically symmetrically distributed. This arrangement facilitates the replacement of the cutting teeth 602 at one end of the cutter 6 after they become dull, thereby extending the service life of a set of cutters 6. The front side of the fixing plate 5 is densely covered with multiple sets of limiting grooves 501 that accommodate the cutters 6 and are evenly arranged laterally. Both ends of the retaining strip 502 are provided with longitudinal mounting holes 503. A fixing frame 505 is provided in front of the fixing plate 5. The fixing frame 505 is a C-shaped frame with the opening facing backward. Both ends of the fixing frame 505 extend to the outside of the two sets of mounting holes 503, and the fixing frame 505... Both ends of the 05 are provided with countersunk holes 506 for inserting bolts to connect and disassemble 503. The rear side of the fixing frame 505 is provided with a movable groove 507 that engages with and abuts the cutter 6 in conjunction with the limiting groove 501. Both the movable groove 507 and the limiting groove 501 are comb-shaped structures. The movable groove 507 on the inner side of the fixing frame 505, in conjunction with the limiting groove 501 on the outer side of the fixing plate 5, limits the lateral position of the cutter 6. This makes it easy to adjust the number and position of the cutters 6 on the outer side of the fixing plate 5 after the fixing frame 505 is removed, so as to meet the cutting requirements of different spacing models of needle array 10. The front side of the cylinder bracket 4 is provided with two sets of vertically extending slide rails 401. The rear side of the fixing plate 5 is fixed with a linear slider 504 that slides vertically in conjunction with the slide rails 401. The bottom telescopic end of the vertical cylinder 8 is connected to a cylinder adapter 801 that supports the fixing plate 5 and drives the cutter 6 to slide vertically to perform the cutting action.

[0040] The base frame 2 is fixed to the top rear side of the base 1. A sliding seat 201 supporting the back-and-forth movement of the mounting plate 3 is fixed to the top of the base frame 2. A longitudinal cylinder 9 is fixed to the rear side of the base frame 2. The telescopic end of the longitudinal cylinder 9 extends longitudinally above the sliding seat 201. A receiving groove 301 is provided on the front side of the mounting plate 3 to accommodate the vertically protruding cutter 6, ensuring that the cutter 6 can vertically cut the needle array 10. A sliding block 302 that longitudinally slides with the sliding seat 201 is fixed to the bottom side of the mounting plate 3. The cylinder bracket 4 is fixed to the top side of the mounting plate 3 by bolts. A lower mold 303 is installed on the top side of the mounting plate 3 by bolts. An upper mold 304 that forms the cutting mold for the needle array 10 is detachably installed above the lower mold 303 by bolts. A receiving groove is provided between the upper mold 304 and the lower mold 303 to accommodate the needle array 10. The needle 10 has a vertically penetrating upper hole 304a and a lower hole 303a, both of which correspond one-to-one with the limiting groove 501. This ensures that the cutter 6 installed in any set of limiting grooves 501 can vertically and sequentially penetrate the upper hole 304a and the lower hole 303a to achieve the cutting action of the needle 10. The bottom side of the mounting plate 3 is provided with a constraint groove 306 for engaging and abutting the sliding seat 201. The mounting plate 3 above the constraint groove 306 is provided with a connection hole 305 for inserting bolts to fix and connect the sliding seat 201. The top front side of the base 1 is provided with two sets of positioning brackets 102. The top of the two sets of positioning brackets 102 is fixed with two sets of positioning blocks 104 that extend to the outer sides of the upper mold 304 respectively. The upper mold 304 is positioned by the positioning blocks 104.

[0041] A support plate 103 is horizontally connected between the two sets of positioning brackets 102. The bottom side of the base frame 2 is fixed to the top of the base 1, and multiple sets of positioning pins 101 for constraining the positioning base frame 2, the support plate 103, and the positioning bracket 102 are vertically protruding from the top side of the base 1. The base frame 2, the support plate 103, and the positioning bracket 102 are all fixed to the top side of the base 1 by bolts. The front telescopic end of the longitudinal cylinder 9 is fixedly connected to the rear side of the sliding block 302 by bolts, ensuring that the longitudinal cylinder 9 can pull the mounting plate 3 to drive the cylinder bracket 4 above it, the fixing plate 5, and the vertical cylinder 8 to move back and forth, which facilitates the replacement and clamping of the row of needles 10 inside the cutting mold. The length of the sliding seat 201 is greater than the longitudinal telescopic stroke of the longitudinal cylinder 9.

[0042] The method of using the cutting device includes the following steps:

[0043] a. Separate the upper mold 304 from the top side of the lower mold 303, place the pin header 10 into the top side of the lower mold 303, and clamp and install the pin header 10 by the upper mold 304 and the lower mold 303, thereby using the upper mold 304 and the lower mold 303 to position the pin header 10 product, and complete the clamping and positioning of the pin header 10 above the mounting plate 3.

[0044] b. According to the number of pins of the pins 10 to be cut, remove the fixing frame 505 from the front of the fixing plate 5. Place several sets of cutters 6 into the corresponding positions of the limiting grooves 501 on the front of the fixing plate 5 at the required cutting positions on the pins 10. Then, fasten the fixing frame 505 to the front of the fixing plate 5. Press the slots 603 of the cutters 6 against the locking strips 502 of the fixing plate 5. Use the movable slots 507 of the fixing frame 505 in conjunction with the limiting grooves 501 of the fixing plate 5 to lock the cutters 6, so as to adjust the number and position of the cutters 6 according to the required cutting positions of the pins 10.

[0045] c. Using the cylinder adapter 801 connected to the bottom telescopic end of the vertical cylinder 8, the fixing plate 5 is pushed to drive multiple sets of cutters 6 to move downward. The fixing plate 5 is guided by the sliding cooperation between the rear linear slider 504 and the slide rail 401. The fixing plate 5 supports the bottom side of the cutter 6 to move downward to the clamping position of the pin row 10 on the top side of the mounting plate 3. The cutting groove 601 at the end of the cutter 6 is used to position the corresponding cutting position of the pin row 10. The cutting groove 601 is used to cut the pin row 10 with several sets of cutting teeth 602 with gradually decreasing gap from the outside to the inside to cut the pin row 10 to the required number of pins.

[0046] By replacing the steel saw blade of the traditional rotating cutting pin 10 with a straight cutting blade 6, the cutting blade 6 is used to punch the pin 10, which solves the problem of high temperature generating plastic burrs caused by the high-speed rotation friction of the steel saw blade as the cutting blade 6, reduces the subsequent deburring process, saves manual labor, and reduces labor costs.

[0047] The fixed plate 5 is densely covered with comb-shaped limiting grooves 501 for mounting the cutter 6. The initial position and spacing of multiple cutters 6 can be adjusted according to the spacing of the needle row 10, so as to complete the multi-position cutting of the needle row 10 in one punching process, thereby helping to improve the mass production speed of industrial products.

[0048] In addition, both ends of the cutter 6 are provided with cutting grooves 601 and cutting teeth 602, which makes it easy to replace the cutter 6 after one end becomes dull or damaged. The multiple sets of cutting teeth 602 are set as a progressive structure with gradually decreasing spacing, which makes it easy to cut the wire cutting area from both sides inward by using multiple sets of cutting teeth 602. This avoids the problem of the traditional cutter 6 having multiple sets of blades with equal width on the circumference, which makes the cutter easy to jam and difficult to cut. The cutting process is smoother.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
