Technical Field

[0001] The utility model relates to the technical field of cutting pins of lead-type electronic components, in particular to a device for cutting pins of lead-type electronic components. Background Art

[0002] Leaded electronic components generally refer to those with leads, which are mainly used to fix and connect components. This type of components is widely used in various electronic devices and systems, such as capacitors, inductors, resistors and temperature sensors.

[0003] For example, a lead-type electronic component cutting device disclosed in Chinese patent CN207839950U controls the operation of the motor by controlling the operation table controller, the motor drives the lead screw to rotate, the lead screw drives the connecting block to move horizontally, thereby driving the support plate below the connecting block to move back and forth along the horizontal direction of the guide rail, and the controller also moves accordingly, the position sensor detects the position of the lead-type electronic component, sends the information to the controller, and the controller controls the cylinder to drive the cutter to move up and down, thereby realizing the cutting action. The entire cutting work is automated, with high cutting efficiency and speed, more accurate position identification, higher product qualification rate, which is conducive to improving the economic benefits of manufacturers, more reasonable structural design, more convenient operation, lower use cost, and conducive to reducing the workload of staff. It is suitable for cutting the pins of various lead-type electronic components, automatically identifies the cutting position, has high practicality, and longer service life.

[0004] Although this structure can be used to cut corners on lead-type electronic components, the cut corner section is relatively rough and has burrs, requiring operators to perform secondary processing and polishing, which is cumbersome. Therefore, we propose a lead-type electronic component cutting device that can deburr the cut surface of lead-type electronic components to avoid the need for secondary processing by operators, thereby improving the convenience of cutting the leads of lead-type electronic components. Utility Model Content

[0005] The utility model aims to provide a lead-type electronic component cutting device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lead-type electronic component cutting device, comprising a lead-cutting equipment body, a conveyor belt is arranged inside the lead-cutting equipment body, a support plate is slidably arranged inside the lead-cutting equipment body, a connecting rod is fixedly installed at the bottom of the support plate, and a processing assembly is arranged at the bottom of the support plate, the processing assembly includes a grinding assembly arranged at the bottom of the support plate, and a soot blowing assembly is arranged outside the grinding assembly.

[0007] Preferably, the grinding assembly includes a telescopic rod fixedly mounted on an end of the connecting rod away from the supporting plate, a cutting head is fixedly mounted on the end of the telescopic rod away from the connecting rod, a limiting frame is fixedly mounted on the inner wall of the cutting head, a first magnetic block is fixedly mounted on the inner wall of the limiting frame, a second magnetic block is slidably arranged inside the limiting frame, a connecting rod is hingedly connected to the outer wall of the second magnetic block, a connecting plate is hingedly connected to the outer wall of the connecting rod away from the second magnetic block, a grinding plate is fixedly mounted on the outer wall of the connecting plate, a fixing plate is fixedly mounted on the outer wall of the cutting head, a sliding rod is slidably arranged inside the fixing plate, a spring is sleeved on the outer wall of the sliding rod, and a pressure plate is fixedly mounted on the end of the sliding rod.

[0008] Preferably, the sootblowing assembly comprises an extrusion rod fixedly mounted on the bottom of the support plate, a sleeve is slidably provided on the outer wall of the extrusion rod, a limiting ring is fixedly mounted on the outer wall of the sleeve, and a connecting block is provided on the inner side of the limiting ring.

[0009] Preferably, the outer wall of the second magnetic block is hingedly connected to the outer wall of the connecting rod, and the connecting plate is hingedly connected to the inside of the cutting head. Under the action of the mutual magnetic repulsion between the first magnetic block and the second magnetic block, the connecting plate hingedly connected to it is pushed by the connecting rod to deflect, so that the polishing plate fixedly installed on the outer wall of the connecting plate is in close contact with the cut surface of the electronic component.

[0010] Preferably, one end of the spring is fixedly mounted on the bottom surface of the fixed plate, and the end of the spring away from the fixed plate is fixedly mounted on the top surface of the pressure plate. The pressure plate is made of rubber material. Under the restriction of the rubber pressure plate, the electronic components can be pressed tightly without damaging the electronic components.

[0011] Preferably, the connecting block is fixedly mounted on the outer wall of the telescopic rod, and the inside of the connecting block is fixedly mounted on the outer wall of the sleeve. When the telescopic rod moves, the connecting block is driven to move accordingly, so that the sleeve fixedly mounted inside the connecting block moves accordingly.

[0012] Preferably, there are three extrusion rods, which are equidistantly distributed at the bottom of the support plate. The outer wall of the extrusion rod is slidably arranged with the inner wall of the sleeve. Since the extrusion rod and the inner wall of the sleeve are sealed and slidably connected, under their restriction, when the sleeve moves upward, the gas inside the sleeve can be pushed by the extrusion rod and then blown above the conveyor belt to disperse the grinding debris.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The lead-type electronic component cutting device is composed of a grinding assembly as one part. When the electronic component needs to be cut, it is placed above the conveyor belt, the telescopic rod is started, and the cutting head is driven to move toward the electronic component. The electronic component is cut through the main body of the lead-cutting device. After the electronic component is cut, the cut surface is rough and needs to be polished. The telescopic rod is continued to drive the cutting head to move downward, so that the grinding plate fixedly installed on the outer wall of the connecting plate hingedly connected to the inner wall of the cutting head is in contact with the cut surface of the electronic component. The cut surface is frictionally polished by the grinding plate. Since the connecting plate is hingedly connected to the inside of the cutting head, and its outer wall is hingedly connected to the connecting rod, the connecting rod is hingedly connected to the second magnetic block slidably arranged inside the limiting frame, under its restriction, the grinding plate can be closely fitted and contacted with the cut surface. When the grinding plate is squeezed by the electronic component, the connecting rod pushes the second magnetic block to slide inside the limiting frame. When the second magnetic block moves toward the inner wall of the limiting frame When the fixed first magnetic block slides in one direction, the second magnetic block is pushed away from the first magnetic block under the action of magnetic mutual repulsion, and the connecting plate is pushed by the connecting rod, so that the grinding plate fixedly installed on the outer wall of the connecting plate is in contact with the cut surface to ensure that the cut surface can be completely contacted and polished. When the cutting head continues to move downward, the fixed plate fixedly installed on its outer wall moves downward accordingly, and the sliding rod sliding inside the fixed plate moves downward accordingly, so that the pressure plate fixedly installed at the end of the sliding rod is in contact with the electronic components. When the fixed plate moves downward, it squeezes and compresses the spring sleeved on the outer wall of the sliding rod. Under the action of the spring elasticity, the pressure plate is pushed to press the electronic components tightly, so that when the grinding plate contacts and polishes the cut surface of the electronic components, the electronic components will not deviate. This structure can polish the cuts of electronic components after the corner cutting is completed (there are existing public technologies in the comparison documents of the cutting foot equipment body, conveyor belt, support plate and connecting rod, so their structure is not fully described in this case).

[0015] 2. The lead-type electronic component cutting device is composed of a soot blowing assembly as one of its components. When the electronic component is cut corners, the telescopic rod drives the cutting head upward, and the connecting block fixedly installed on the outer wall of the telescopic rod moves upward accordingly, and the sleeve fixedly installed inside the connecting block moves upward accordingly. The inner wall of the sleeve and the outer wall of the extrusion rod slide in a sealed manner, and the extrusion rod pushes and compresses the gas inside the sleeve. The pushed-out gas blows away the debris and powder polished from the cut surface of the electronic component, thereby ensuring the accuracy of the next electronic component cutting corner. Under the support of the limit ring, the sleeve can be driven to move downward stably when the connecting block moves downward. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] A preferred embodiment of a lead-type electronic component cutting device provided by the utility model is as follows Figures 1 to 6 As shown: a lead-type electronic component cutting device, including a lead-cutting device body 1;

[0026] A conveyor belt 2 is arranged inside the main body 1 of the leg cutting device;

[0027] A support plate 3 is slidably arranged inside the main body 1 of the foot cutting device;

[0028] A connecting rod 4 is fixedly installed at the bottom of the support plate 3;

[0029] And a processing component 5 arranged at the bottom of the support plate 3, the processing component 5 includes a grinding component 51 arranged at the bottom of the support plate 3, the grinding component 51 includes a telescopic rod 511 fixedly installed on the end of the connecting rod 4 away from the support plate 3, the end of the telescopic rod 511 away from the connecting rod 4 is fixedly installed with a cutting head 512, the inner wall of the cutting head 512 is fixedly installed with a limiting frame 513, the inner wall of the limiting frame 513 is fixedly installed with a first magnetic block 514, the inner wall of the limiting frame 513 is fixedly installed with a second magnetic block 515, the outer wall of the second magnetic block 515 is hingedly connected with a connecting rod 516, the end of the connecting rod 516 away from the second magnetic block 515 is hingedly connected with a connecting plate 517, the outer wall of the connecting plate 517 is fixedly installed with a grinding plate 522, the outer wall of the cutting head 512 is fixedly installed with a fixed plate 518, the fixed plate 518 is slidably provided with a sliding rod 519, the outer wall of the sliding rod 519 is sleeved with a spring 520, and the end of the sliding rod 519 is fixedly installed with a pressing plate 521.

[0030] In this embodiment, when it is necessary to perform corner cutting on the electronic components, the electronic components are placed above the conveyor belt 2, the telescopic rod 511 is started, and the cutting head 512 is driven to move toward the electronic components. The electronic components are cut by the cutting device body 1. After the electronic components are cut, the cut surface is rough and needs to be polished. The telescopic rod 511 is continued to drive the cutting head 512 to move downward, so that the polishing plate 522 fixedly installed on the outer wall of the connecting plate 517 hingedly connected to the inner wall of the cutting head 512 contacts the cut surface of the electronic components. The plate 522 is frictionally polished against the cut surface. Since the connecting plate 517 is hingedly connected to the inside of the cutting head 512, and its outer wall is hingedly connected to the connecting rod 516, the connecting rod 516 is hingedly connected to the second magnetic block 515 slidably set inside the limiting frame 513. Under its restriction, the polishing plate 522 can be closely fitted and contacted with the cut surface. When the polishing plate 522 is squeezed by the electronic components, the connecting rod 516 pushes the second magnetic block 515 to slide inside the limiting frame 513. When the second magnetic block 515 moves toward the first magnetic block fixedly installed on the inner wall of the limiting frame 513, the second magnetic block 515 moves toward the first magnetic block fixedly installed on the inner wall of the limiting frame 513. When the cutting head 512 slides in the direction of 514, under the effect of magnetic mutual repulsion, the second magnetic block 515 is pushed away from the first magnetic block 514, and the connecting plate 517 is pushed by the connecting rod 516, so that the grinding plate 522 fixedly installed on the outer wall of the connecting plate 517 is in contact with the cut surface to ensure that the cut surface can be completely contacted and polished. When the cutting head 512 continues to move downward, the fixed plate 518 fixedly installed on its outer wall moves downward accordingly, and the sliding rod 519 slidingly arranged inside the fixed plate 518 moves downward accordingly, so that the pressing plate 521 fixedly installed at the end of the sliding rod 519 is in contact with the electronic component Device contact, when the fixed plate 518 moves downward, it squeezes and compresses the spring 520 mounted on the outer wall of the sliding rod 519, and under the elastic effect of the spring 520, the pressing plate 521 is pushed to press the electronic components, so that when the polishing plate 522 contacts and polishes the cut surface of the electronic components, the electronic components will not deviate. This structure can polish the cuts of electronic components after the corners are cut (the cutting equipment body 1, conveyor belt 2, support plate 3 and connecting rod 4 are existing public technologies in the comparative documents, so their structure is not fully described in this case).

[0031] Furthermore, the outer wall of the second magnetic block 515 is hingedly connected to the outer wall of the connecting rod 516, and the connecting plate 517 is hingedly connected to the inside of the cutting head 512. Under the action of the mutual magnetic repulsion between the first magnetic block 514 and the second magnetic block 515, the connecting plate 517 hingedly connected thereto is pushed by the connecting rod 516 to deflect, so that the polishing plate 522 fixedly installed on the outer wall of the connecting plate 517 is in close contact with the cut surface of the electronic component.

[0032] Furthermore, one end of the spring 520 is fixedly installed on the bottom surface of the fixed plate 518, and the end of the spring 520 away from the fixed plate 518 is fixedly installed on the top surface of the pressure plate 521. The pressure plate 521 is made of rubber material. Under the restriction of the rubber pressure plate 521, the electronic components can be pressed tightly without damaging the electronic components.

[0034] On the basis of Example 1, a preferred embodiment of a lead-type electronic component cutting device provided by the utility model is as follows: Figures 1 to 6 As shown: the sootblowing assembly 53 includes an extrusion rod 531 fixedly installed at the bottom of the support plate 3, a sleeve 532 is slidably provided on the outer wall of the extrusion rod 531, a limiting ring 534 is fixedly installed on the outer wall of the sleeve 532, and a connecting block 533 is provided on the inner side of the limiting ring 534.

[0035] In this embodiment, when the corner cutting of the electronic component is completed, the telescopic rod 511 drives the cutting head 512 upward, and the connecting block 533 fixedly installed on the outer wall of the telescopic rod 511 moves upward accordingly, and the sleeve 532 fixedly installed inside the connecting block 533 moves upward accordingly, and the inner wall of the sleeve 532 and the outer wall of the extrusion rod 531 slide in a sealed manner, and the extrusion rod 531 pushes and compresses the gas inside the sleeve 532, and the pushed out gas blows away the debris and powder polished from the cut surface of the electronic component, thereby ensuring the accuracy of the next corner cutting of the electronic component. Under the support of the limit ring 534, the connecting block 533 can move downward, driving the sleeve 532 to move downward stably.

[0036] Furthermore, the connecting block 533 is fixedly installed on the outer wall of the telescopic rod 511, and the interior of the connecting block 533 is fixedly installed on the outer wall of the sleeve 532. When the telescopic rod 511 moves, the connecting block 533 is driven to move accordingly, so that the sleeve 532 fixedly installed inside the connecting block 533 moves accordingly.

[0037] In addition, there are three extrusion rods 531, which are equidistantly distributed at the bottom of the support plate 3. The outer wall of the extrusion rod 531 is slidably arranged with the inner wall of the sleeve 532. Since the extrusion rod 531 and the inner wall of the sleeve 532 are sealed and slidably, under their restriction, when the sleeve 532 moves upward, the gas inside the sleeve 532 can be pushed by the extrusion rod 531 and then blown to the top of the conveyor belt 2 to blow away the grinding debris.

[0038] The above is only an illustrative specific implementation method of the utility model, and is not intended to limit the scope of the utility model. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the utility model should fall within the scope of protection of the utility model. It should also be noted that the various components of the utility model are not limited to the above-mentioned overall application. The various technical features described in the specification of the utility model can be selected one by one or multiple ones can be selected and used in combination according to actual needs. Therefore, the utility model should naturally cover other combinations and specific applications related to the utility model points of this case.
