Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing equipment, and particularly to a laser peeling mechanism for transformers. Background Art

[0002] Existing various transformer electronic components mainly consist of an iron core and coils. Different coils are cooperated to achieve different voltage transformation functions. During the production process, after the transformer is initially assembled, it is necessary to expose the pins of the coils with paint coatings and perform a peeling operation on the pins to facilitate subsequent soldering to prepare the transformer pins. However, existing semi-automatic laser peeling machines all use manual labor to place multiple transformers to be peeled one by one onto the processing fixtures of the semi-automatic laser peeling machine, and then use a laser peeling device to perform peeling treatment on the transformers carried by the processing fixtures. Whether the placement of the transformers is precise and stable directly affects the peeling quality of the transformers, and the placement of the transformers is related to the proficiency of the workers. If the workers operate unskilledly, it is easy to cause the transformers to be damaged by the laser and scrapped. Seriously, even safety accidents may occur; in addition, the manual feeding method has low production efficiency and high labor costs. This defect is very obvious and an effective solution is urgently needed. Summary of the Invention

[0022] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present invention. The present invention will be described in detail below with reference to the drawings.

[0023] As Figures 1 to 6As shown in the figure, a laser peeling mechanism for a transformer provided by the present invention includes a machine table 21, an upper clamping manipulator 22 installed on the machine table 21, a lower clamping manipulator 23 installed on the machine table 21, and a peeling device 24 installed on the machine table 21. The upper clamping manipulator 22 is used to transfer the transformer to be peeled from the outside to the lower clamping manipulator 23. The lower clamping manipulator 23 clamps the transformer output by the upper clamping manipulator 22 and transfers it to the peeling device 24. The peeling device 24 is used to perform peeling treatment on the transformer clamped by the lower clamping manipulator 23. Specifically, the peeling device 24 is an existing laser peeling machine.

[0024] In practical applications, the transformer to be peeled is conveyed to the picking position of the upper clamping manipulator 22 through an external conveying mechanism. The upper clamping manipulator 22 picks up the transformer and transfers it above the lower clamping manipulator 23. The lower clamping manipulator 23 clamps the inner cavity of the transformer clamped by the upper clamping manipulator 22. Then, the lower clamping manipulator 23 clamps the transformer and moves it to the peeling device 24, so that the peeling device 24 can perform laser peeling treatment on the pins of the transformer clamped by the lower clamping manipulator 23. After laser peeling, the lower clamping manipulator 23 drives the peeled transformer back below the upper clamping manipulator 22. The upper clamping manipulator 22 clamps the peeled transformer and unloads the transformer. The structural design of the present invention is simple and compact. The feeding by the manipulator is stable and accurate. With the cooperation of the upper clamping manipulator 22 and the lower clamping manipulator 23, automatic feeding and peeling treatment of the transformer can be realized. The whole process has a high degree of automation and does not require manual operation, further reducing labor costs and improving the production efficiency and production quality of the transformer.

[0025] In this technical solution, the upper clamping manipulator 22 includes a support frame 221 installed on the machine table 21, a clamping device 27 movably arranged on the support frame 221, and a first driving device 25 installed on the support frame 221 and used to drive the clamping device 27 to move and lift. The clamping device 27 is located above the lower clamping manipulator 23. The clamping device 27 is used to clamp the outer side of the transformer. During operation, the first driving device 25 drives the clamping device 27 to lift and lower to clamp the transformer or place the clamped transformer, and the first driving device 25 drives the clamping device 27 to move to transfer the clamped transformer.

[0026] Preferably, the first driving device 25 includes a moving block 251 slidably arranged on the support frame 221, a clamping movement driving device 252 installed on the support frame 221 and used to drive the moving block 251 to move, and a clamping lifting driving device 253 installed on the moving block 251. The clamping device 27 is drivingly connected to the clamping lifting driving device 253.

[0027] The clamping device 27 includes a clamping fixed block 271 drivingly connected to the clamping lifting driving device 253, two clamping blocks 272 movably arranged on the clamping fixed block 271, and an opening and closing driving device 273 for driving the two clamping blocks 272 to approach or separate from each other. Specifically, a positioning boss 274 for abutting and positioning the top of the transformer is protruded outward from the clamping surface of one of the clamping blocks 272. The design of the positioning boss 274 enables the two clamping blocks 272 to firmly clamp the transformer and play a role in positioning the transformer, thereby ensuring the accuracy of the processing position of the transformer and improving the peeling quality of the transformer.

[0028] Specifically, the clamping movement driving device 252 adopts an existing linear module. The clamping lifting driving device 253 adopts an existing driving cylinder. The opening and closing driving device 273 can adopt a finger cylinder.

[0029] In practical applications, a feeding fixture 122 and a fixture driving device 121 for driving the feeding fixture 122 are arranged at the feeding end of the machine table 21; the fixture driving device 121 is an existing linear module. The clamping movement driving device 252 drives the clamping device 27 to move back and forth between the feeding fixture 122 and the lower clamping manipulator 23. When the clamping device 27 clamps the transformer output by the feeding fixture 122, the clamping lifting driving device 253 drives the clamping device 27 to descend, so that the two clamping blocks 272 are respectively located outside the transformer. At this time, the opening and closing driving device 273 drives the two clamping blocks 272 to approach each other, so that the two clamping blocks 272 can clamp the outside of the transformer, thereby realizing the clamping of the transformer; then the clamping device 27 clamps the transformer and moves it above the lower clamping manipulator 23, and the lower clamping manipulator 23 clamps the inner cavity of the transformer, and then the lower clamping manipulator 23 drives the transformer to move to the peeling device 24 for laser peeling treatment; after the peeling treatment is completed, the lower clamping manipulator 23 clamps the transformer and moves it below the clamping device 27, and the clamping device 27 clamps the transformer clamped by the lower clamping manipulator 23 again. Then the clamping device 27 clamps the transformer and transfers it to other processing mechanisms or unloads the transformer.

[0030] Specifically, two clamping lifting driving devices 253 and two clamping devices 27 are arranged on the moving block 251, and the two clamping devices 27 are respectively drivingly connected to the two clamping lifting driving devices 253 in one-to-one correspondence. The design of the two clamping devices 27 enables the upper clamping manipulator 22 to realize the synchronous work of clamping and unloading, thereby improving the production efficiency of the present invention.

[0031] In this technical solution, the lower clamping manipulator 23 includes a movable seat 231 movably arranged on the machine table 21, a clamping assembly 232 arranged on the movable seat 231, a rotation driving device 233 arranged on the movable seat 231 and used to drive the clamping assembly 232 to rotate, and a second driving device 26 used to drive the movable seat 231 to move and lift on the machine table 21. The peeling device 24 is located above the clamping assembly 232. Specifically, the rotation driving device 233 adopts a driving mechanism that combines a driving motor and a belt transmission mechanism, which makes the rotation of the clamping assembly 232 stable, noiseless and has high rotation accuracy.

[0032] In practical applications, the clamping assembly 232 is used to clamp the inner cavity of the transformer clamped by the upper clamping manipulator 22. The second driving device 26 moves the clamping assembly 232 below the upper clamping manipulator 22, and then the second driving device 26 raises the clamping assembly 232 so that the clamping assembly 232 extends into the inner cavity of the transformer and clamps the side wall of the inner cavity, thereby realizing the clamping of the middle part of the transformer. After the clamping assembly 232 clamps the transformer, the second driving device 26 drives the clamping assembly 232 together with the transformer to move below the peeling device 24. Then, the rotation driving device 233 drives the clamping assembly 232 to rotate, and the rotating clamping assembly 232 drives the transformer to rotate; the clamping assembly 232 drives the transformer to rotate so that the pins on each side of the transformer can be aligned with the laser emission position of the peeling device 24, so that the peeling device 24 can perform laser peeling treatment on the pins of the transformer. The design of the lower clamping manipulator 23 can enable the clamping assembly 232 to directly clamp the inner cavity of the transformer from below, and the rotation of the clamping assembly 232 enables the transformer to rotate forward and backward at any angle, so that the pins of the transformer can be aligned with the laser peeling machine; the whole process has a high degree of automation, runs at high speed and stably. In the present invention, there is no need to use other mechanisms to flip the transformer before feeding, and then use a manipulator to clamp the transformer for laser peeling treatment, thereby improving the production efficiency of the whole transformer peeling treatment; at the same time, the operation of this method can also enable the transformer to be output in the same conveying state as when feeding, which is convenient for the processing of the next process.

[0033] Preferably, the second driving device 26 includes a Y-axis driving device 261 installed on the machine table 21 and used to drive the movable seat 231 to move along the Y-axis of the machine table 21, an X-axis driving device 262 drivingly connected to the Y-axis driving device 261 and used to drive the movable seat 231 to move along the X-axis of the machine table 21, and a Z-axis driving device 263 drivingly connected to the X-axis driving device 262 and used to drive the movable seat 231 to lift. The movable seat 231 is drivingly connected to the Z-axis driving device 263. Specifically, both the X-axis driving device 262 and the Y-axis driving device 261 adopt the mechanism of a linear driving module. The X-axis driving device 262 is drivingly connected to the output end of the Y-axis driving device 261 (i.e., connected to the sliding block of the linear driving module) through the cooperation of a guide rail and a slider, so that the Y-axis driving device 261 can drive the X-axis driving device 262 to move along the Y-axis of the machine table 21. The structure of the second driving device 26 is simple and compact, easy to assemble, easy to maintain, and has stable movement and high precision. The design of the second driving device 26 can make the movement of the transformers clamped in a row more accurate. Under the movement error, the position positioning accuracy of the transformers is high, so that the paint on the pins is easy to remove and is removed more cleanly, thereby improving the peeling quality of the present invention.

[0034] In practical applications, the Y-axis driving device 261 drives the clamping assembly 232 to move back and forth between the upper feeding manipulator 22 and the peeling device 24. The clamping assembly 232 can clamp a plurality of transformers. The plurality of transformers are linearly arranged along the X-axis of the machine table 21. The X-axis driving device 262 drives the clamping assembly 232 to move along the X-axis of the machine table 21 under the laser peeling machine, so that the pins of the plurality of transformers clamped by the clamping assembly 232 can all contact the laser emitted by the laser peeling machine, thereby enabling the plurality of transformers to all complete the peeling process.

[0035] Preferably, the clamping assembly 232 includes a finger rotating member 234 rotatably arranged on the movable seat 231 and clamping fingers 235 arranged on the finger rotating member 234. The finger rotating member 234 is drivingly connected to the rotation driving device 233.

[0036] The clamping fingers 235 are used to clamp the inner cavity of the transformer. The rotation driving device 233 drives the finger rotating member 234 to rotate in the positive and negative directions around the X-axis of the machine table 21. The rotating finger rotating member 234 drives the clamping fingers 235 to rotate in the positive and negative directions around the X-axis of the machine table 21, and the rotating clamping fingers 235 drive the transformer to rotate. The clamping fingers 235 include a finger driving device 2351 installed on the finger rotating member 234 and two finger clamping blocks 2352 drivingly connected to the finger driving device 2351. The finger driving device 2351 is used to drive the two finger clamping blocks 2352 to open or close. The finger driving device 2351 can adopt a finger cylinder. The outer side of the finger clamping block 2352 is concavely provided with a groove 2353 for matching the shape of the inner wall of the transformer, and the top of the finger clamping block 2352 protrudes upward with a semi-cylinder 2354. Since the inner cavity of the transformer is a circular hollow groove, when the two finger clamping blocks 2352 are closed, the two semi-cylinders 2354 form a cylinder with a diameter smaller than the diameter of the inner cavity of the transformer, so that the cylinder formed after the combination of the two finger clamping blocks 2352 can enter the inner cavity of the transformer; when the cylinder enters the inner cavity of the transformer, the finger driving device 2351 drives the two finger clamping blocks 2352 to open, then the two semi-cylinders 2354 of the two finger clamping blocks 2352 respectively abut against the two side walls of the inner cavity of the transformer, and the two grooves 2353 of the two finger clamping blocks 2352 respectively abut against the edges of the inner wall of the transformer, and the side walls of the grooves 2353 limit the edges of the inner wall of the transformer to prevent the transformer from rotating during the movement or peeling process, so as to ensure the stability and quality of the peeling of the transformer.

[0037] Specifically, one end of the finger rotating member 234 is connected with an induction sheet, and the rotation of the finger rotating member 234 drives the induction sheet to rotate; one end of the movable seat 231 close to the induction sheet is provided with an inductor for inductively cooperating with the induction sheet, and the inductor can be an existing infrared inductor. In practical applications, when the finger rotating member 234 rotates to a preset position, the rotating finger rotating member 234 drives the induction sheet to rotate to the inductor position of the inductor to trigger the inductor. At this time, the inductor sends a command to the rotation driving device 233 to command the rotation driving device 233 to stop driving, thereby positioning the finger rotating member 234 at a preset rotation angle. The design of this structure can limit the rotation angle of the finger rotating member 234 to prevent the finger rotating member 234 from rotating excessively and avoid the laser of the peeling device 24 from emitting to other parts of the transformer.

[0038] In practical applications, the upper material clamping manipulator 22 clamps the transformer output by the second conveying device 12 and transfers it above the lower material clamping manipulator 23. The Z-axis driving device 263 drives the clamping assembly 232 to drive the material clamping fingers 235 to rise, so that the cylinders of the two closed finger blocks 2352 enter the inner cavity of the transformer. Then, the two finger blocks 2352 expand so that the material clamping fingers 235 clamp the inner cavity of the transformer. Next, the upper material clamping manipulator 22 releases the clamping of the transformer, the Z-axis driving device 263 drives the clamping assembly 232 to descend, and then the X-axis driving device 262 drives the clamping assembly 232 to move below the laser peeling machine. Moreover, the rotation driving device 233 drives the finger rotating member 234 to rotate, and the rotating finger rotating member 234 drives the material clamping fingers 235 to rotate. The rotating material clamping fingers 235 drive the transformer to rotate to a specified angle, so that the pins of the transformer can be aligned with the processing position of the laser peeling machine. When the peeling process of the transformer is completed, the X-axis driving device 262 drives the clamping assembly 232 to move below the upper material clamping manipulator 22. At the same time, the rotation driving device 233 drives the finger rotating member 234 to reset so that the transformer is in a vertical state, which is convenient for the upper material clamping manipulator 22 to re-clamp the transformer and transfer the peeled transformer to the transformer transfer mechanism 104.

[0039] The structure of the lower material clamping manipulator 23 is designed simply and compactly. Its material clamping fingers 235 can realize multi-axis linkage, so that the material clamping fingers 235 can realize the simulation of the human hand's motion, thereby driving the pins of the transformer to achieve laser peeling treatment without dead angles, and thus improving the peeling quality of the transformer.

[0040] In summary, through the cooperation of the upper material clamping manipulator 22 and the lower material clamping manipulator 23, the present invention can quickly, stably and accurately transfer the external transformer to be peeled to the processing position of the peeling device 24, so that the peeling device 24 can accurately perform laser peeling treatment on the pins of the transformer. At the same time, the rotation of the clamping assembly 232 drives the clamped transformer to rotate, so that the transformer is flipped, that is, in the way of simulating manual operation, so that the pins on both sides of the transformer can be in contact with the laser emitted by the peeling device 24, thereby completing the automatic laser peeling treatment of the transformer.
