Description

Electronic component processing equipment and processing machines

The present invention provides an electronic component operating device which can ensure that a workpiece is accurately positioned at a preset operating position to improve the operating quality.

Nowadays, the operating mechanism (such as the conveying mechanism or the testing mechanism) of the electronic component processing machine is equipped with operators with different functions (such as a carrier, a crimper or a tester, etc.) to perform different preset operations on the electronic components (such as conveying operations, crimping operations or testing operations, etc.). Since electronic components will be used in high-temperature places in the future, in order to ensure the quality of electronic components, the industry must perform thermal testing operations on electronic components. Under the condition that electronic components are becoming more and more precise and small, the accuracy of the preset operation position of the operator is required to be very high.

As for the carrier of the conveying mechanism, the carrier is provided with a slot for holding electronic components. The carrier is mounted on a moving seat, and the moving seat drives the carrier and the electronic components to move to one side of the tester for taking and placing electronic components. However, in order to shorten the heating time of the electronic components in the tester, the carrier is equipped with a heating element to heat the electronic components during the transportation of the electronic components. However, the slot of the carrier is deformed due to thermal expansion, causing the slot to deviate from the preset position for taking and placing materials, so that the crimper cannot accurately take out the electronic components to be tested or place the tested electronic components in the slot of the carrier, thereby affecting the accuracy of the operation, and may even place the electronic components in the slot at an angle, causing the crimper to damage the electronic components.

As for the crimper and tester of the testing mechanism, both the crimper and the tester are located in the thermal testing room so as to perform thermal testing on the electronic components. The crimper is also equipped with a temperature control unit to heat the electronic components to the preset thermal testing temperature. If the crimper is deformed due to thermal expansion and deviates from the preset crimping position, the center of the crimper cannot be accurately aligned with the center of the tester to place the electronic component to be tested, or the pressure applied is uneven, thereby affecting the test quality. Similarly, if the tester is deformed due to thermal expansion and deviates from the preset test position, the crimper cannot be accurately placed on the electronic component to be tested, thereby affecting the test quality.

Therefore, it is very important to improve the operating position accuracy and operating quality of the operator.

The first object of the present invention is to provide an electronic component working device, comprising a working mechanism and a positioning mechanism. The working mechanism is provided with a carrier and a working piece. The carrier is used to assemble at least one working piece with a first expansion coefficient.

The positioning mechanism is provided with at least one positioning tool with a second expansion coefficient, and the second expansion coefficient is smaller than the first expansion coefficient. The positioning tool is provided with at least one limiting part, which can limit the outer peripheral surface of the working piece. When the working piece performs the electronic component thermal measurement operation and is deformed by thermal expansion, the second expansion coefficient of the positioning tool is smaller than the first expansion coefficient of the working piece. The positioning tool is precisely limited to the outer circumference of the workpiece to form a stop layer to prevent the workpiece from deviating, so that the workpiece is accurately positioned at the preset working position, thereby improving the work quality and convenience.

In this embodiment, the at least one positioning mechanism of the working device 40 includes a first positioning mechanism, a second positioning mechanism, and a third positioning mechanism.

The first positioning mechanism is provided with a first positioning tool 44, which is made of stainless steel and has a second expansion coefficient that is smaller than the first expansion coefficient of the first carrier fixture 413 of the first operating mechanism. The first positioning tool 44 is provided with a plurality of first frame limiting parts 441 with hollow holes, and the plurality of first frame limiting parts 441 are provided for inserting a plurality of first carrier fixtures 413. The inner circumference of the first frame limiting part 441 fits the outer circumference of the first carrier fixture 413, so that the first frame limiting part 441 frames the first carrier fixture 413 to form a first blocking layer.

The third positioning tool 46 is assembled on the third connecting seat 432 of the third operating mechanism.

According to the operation requirements, the operation device 40 is provided with a test chamber 47 on the machine 10. The test chamber 47 is equipped with a blower (not shown) to blow hot air to increase the temperature inside the test chamber 47.

According to the operation requirements, the operation device 40 further includes a first conveyor 481, a second conveyor 482 and a third conveyor 483. The first conveyor 481 can be displaced in the X-Y-Z direction to transfer the electronic components to be tested between the feeding device 20 and the first carrier fixture 413; the second conveyor 482 can be displaced in the X direction to allow the second crimper 422 to insert the tested electronic components and carry out the tested electronic components; the third conveyor 483 can be displaced in the X-Y-Z direction to transfer the tested electronic components between the second conveyor 482 and the receiving device 30, and according to the test results, the tested electronic components are transported to the receiving device 30 for classification and collection.

Please refer to Figures 1, 5-7. The operating device 40 uses the first conveyor 481 to move in the X-Y-Z direction to transfer the plurality of electronic components to be tested of the feeding device 20 to the first receiving portion 414 of the plurality of first carrier fixtures 413 of the first operating mechanism; the first operating mechanism drives the first moving seat 411 to move in the X direction with the first driving source 412, and the first moving seat 411 drives the plurality of first carrier fixtures 413, the first positioning fixture 44 and the plurality of electronic components to be tested to move in the X direction synchronously, and during the carrying process, the first heating element 415 is used to heat the electronic components to be tested; however, in order to prevent the first carrier fixture 413 from deviating from the preset pick-up and discharge position due to the large first expansion coefficient and thermal expansion deformation, the first heating element 415 can be used to prevent the first carrier fixture 413 from deviating from the preset pick-up and discharge position due to thermal expansion deformation. The second expansion coefficient of the first positioning tool 44 of a positioning mechanism is smaller than the first expansion coefficient of the first carrier fixture 413, and the first positioning tool 44 maintains a fixed shape and length, so that the first frame limiting portion 441 of the first positioning tool 44 forms a first blocking layer on the outer peripheral surface of the first carrier fixture 413; when the first carrier fixture 413 expands and deforms due to heat and wants to shift horizontally, the first frame limiting portion 441 of the first positioning tool 44 stops the first carrier fixture 413 from shifting horizontally, and limits the first carrier fixture 413 to a preset loading and unloading position, so that the center distance of the plurality of first carrier fixtures 413 remains unchanged, thereby making the plurality of first carrier fixtures 413 carrying the plurality of electronic components to be tested accurately located at the preset loading and unloading positions.

When the plurality of first carrier fixtures 413 carry the plurality of electronic components to be tested to one of the third test seats 433, the second operating mechanism drives the second temperature controller 423, the plurality of second crimpers 422 and the second positioning device 45 to synchronously move in the Y-Z direction with the second moving arm 421. Since the second temperature controller 423 has a cooling chip, the plurality of second crimpers 422 will be heated. However, in order to prevent the second crimpers 422 from deviating from the preset crimping position due to the large first expansion coefficient and thermal expansion deformation, the second crimper 422 can be used. The second expansion coefficient of the second positioning fixture 45 of the second positioning mechanism is less than the first expansion coefficient of the second crimping device 422, and the second positioning fixture 45 maintains a fixed shape and length, so that the second frame limiter 451 of the second positioning fixture 45 forms a second stop layer on the outer peripheral surface of the pressing seat 4221 of the second crimping device 422; when the plurality of second crimping devices 422 are deformed by thermal expansion and want to be horizontally offset, the plurality of second frame limiters 451 of the second positioning fixture 45 can stop the plurality of second crimping devices 422 from being horizontally offset, and the plurality of second crimping devices 422 are framed at the preset crimping position, so that the center distance of the plurality of second crimping devices 422 remains unchanged, and the plurality of electronic components to be tested can be accurately taken out from the plurality of first carrier fixtures 413.

The plurality of second crimpers 422 transfer the plurality of electronic components to be tested to the top of the plurality of third test seats 433. However, in order to prevent the third test seat 433 from deviating from the preset test position due to the large first expansion coefficient and thermal expansion deformation, the second expansion coefficient of the third positioning tool 46 of the third positioning mechanism can be smaller than the first expansion coefficient of the third test seat 433, and the third positioning tool 46 maintains a fixed shape and length, so that the third frame portion 461 of the third positioning tool 46 forms a third blocking layer on the outer peripheral surface of the third test seat 433; When the plurality of third test sockets 433 are deformed due to thermal expansion and want to be horizontally offset, the plurality of third frame portions 461 of the third positioning device 46 prevent the plurality of third test sockets 433 from being horizontally offset, and frame the plurality of third test sockets 433 at the preset test position, so that the center distance of the plurality of third test sockets 433 remains unchanged, so that the plurality of second crimpers 422 can be accurately placed and crimped to the plurality of electronic components to be tested, and the plurality of third test sockets 433 perform testing operations on the plurality of electronic components to be tested, thereby improving the test quality. After the test is completed, the plurality of second crimpers 422 move the plurality of tested electronic components into the second conveyor 482, and the second conveyor 482 outputs the plurality of tested electronic components for the third conveyor 483 to take out the plurality of tested electronic components. The third conveyor 483 transports the tested electronic components to the receiving device 30 for classification and storage according to the test results.
