Description

Technical Field

[0001] The present invention relates to the field of test transportation, and particularly to a test transportation device for electronic components in multiple fields. Background Art

[0002] Electronic components are functional devices in electronic products and are basic components that make up electronic products. There are many types of electronic components, and the functions they achieve are different from each other. However, in order to ensure the control quality of electronic products, it is essential to produce and test each electronic component.

[0003] Based on the increasing development of social technology and the high demand for production efficiency, the detection of electronic components has changed from manual testing to automated testing. In the invention with the patent application number CN205862802U, a device for chip programming and testing is proposed. This device drives a suction rod to grab the programmed chip by setting a linear motor, and uses a magnetic grating ruler and a magnetic grating reading head to cooperate with each other to accurately indicate the movement of the linear motor. At the same time, it has the advantages of being easy to install and having a high transportation speed.

[0004] However, in this solution, a buffer spring is installed between the middle support seat and the linear motor. When the device fails, since the middle support seat itself is a fixed structure, the linear motor is limited on the guiding magnetic rod. At the same time, multiple groups of linear motors are often required. The buffer springs installed on the inner linear motor will greatly affect the disassembly of the device, making it difficult to repair the device and the subsequent maintenance very cumbersome. This technical solution uses a suction rod to grab the chip and transport the chip. However, in the electronic product production line, there are many electronic components to be detected, and some electronic components have extremely high requirements for the grabbing effect (no scratches, fingerprints, suction cup marks, etc. should appear during the grabbing process). The grabbing method using a suction rod can no longer meet the grabbing effect. Due to the limitation of the buffer spring, it is very troublesome to re-adapt the existing components, resulting in difficulty in expanding the application range of this device.

In addition, unless otherwise clearly defined and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

[0038] Referring to Figures 1-7 , an embodiment provided by the present invention includes:

[0039] The fixed installation component includes a first mounting bracket 1, a second mounting bracket 3, and a limit fixing base 5. The first mounting bracket 1 is arranged at the rearmost side of the device, the second mounting bracket 3 is arranged on the right side of the first mounting bracket 1, and the limit fixing base 5 is arranged at the bottom of the first mounting bracket 1;

[0040] The driving component includes a linear motor 10 arranged at the front side of the middle part of the first mounting bracket 1 and a rotating motor 9 arranged in front of the linear motor 10;

[0041] The grasping mechanism 7 is used to grasp the electronic components to be tested. The grasping mechanism 7 includes a connecting rod 701 arranged at the upper part of the grasping mechanism 7 and a gripper 702 arranged at the lower part of the grasping mechanism 7;

[0042] The connecting mechanism 8 is used to connect the driving component and the grasping mechanism 7. The connecting mechanism 8 is fixedly arranged below the rotating motor 9, and the bottom end of the connecting mechanism is fixedly connected with the grasping mechanism 7;

[0043] The buffer spring 6 plays a role in shock absorption and buffering. The top end of the buffer spring 6 is connected with the stable collar 801, and the bottom end of the buffer spring 6 is connected with the fixed block arranged on the limit fixing base 5.

[0044] Furthermore, the top end of the connecting rod 701 is provided with an interface part 705. Three groups of uniformly arranged bayonets 707 are arranged on the side of the interface part 705. The lower part of the interface part 705 is provided with a threaded part 706, and a threaded groove adapted to the threaded part 706 is arranged on the inner wall of the connecting sleeve 802.

[0045] Through this technical solution, the connecting rod 701 and the connecting sleeve 802 are fixed by screwing, which is convenient for replacing the grasping mechanism 7.

[0046] The connecting mechanism 8 is provided with a connecting sleeve 802. A stable collar 801 is arranged on the outside of the connecting sleeve 802. Three groups of uniformly distributed lateral limit boxes 803 are arranged on the side surface of the stable collar 801. A control room 805 is arranged inside the connecting sleeve 802. A control sensor 806 is arranged inside the control room 805. A first top plate 807 is arranged at the bottom of the control room 805. A guide rod 810 is arranged at the bottom of the first top plate 807. A second top plate 809 is sleeved on the lower part of the guide rod 810. A compression spring 808 is arranged between the first top plate 807 and the second top plate 809, and the compression spring 808 is sleeved on the outside of the guide rod 810.

[0047] Through this technical solution, during the screwing-in process of the connecting rod 701, the interface portion 705 contacts the second top plate 809. As the connecting rod 701 is screwed in, the interface portion 705 jacks up the second top plate 809 and the first top plate 807. At the same time, the control sensor 806 can sense the parameter changes in the control chamber 805. When the sensed value of the control sensor 806 reaches the preset value, it indicates that the installation position of the connecting rod 701 is exactly suitable. During this process, the compression spring 808 between the first top plate 807 and the second top plate 809 can improve the connection tightness, avoid connection looseness, and at the same time has the function of shock absorption and energy absorption. The control sensor 806 can be set as a pressure sensor to measure the pressure between the first top plate 807 and the second top plate 809. When the measured pressure reaches the preset value, the installation is completed. The control sensor 806 can also be set as a gas density sensor. At this time, it is necessary to design to ensure that the inside of the control chamber 805 is a closed environment. When the connecting rod 701 is screwed in, it needs to jack up and compress the control chamber 805. When the control sensor 806 measures that the gas density reaches the preset value, it indicates that the installation position of the connecting rod 701 is exactly suitable. By means of the internally arranged control sensor 806 to indicate the installation position of the connecting rod 701, it is ensured that when multiple sets of grasping mechanisms 7 are installed on the device, their installation positions are consistent, thereby reducing the grasping error during the subsequent cooperation process. At the same time, it can also provide installation instructions when replacing different grasping mechanisms 7, reducing the correction and adjustment in the later stage of installation, and facilitating the expansion and application of different grasping mechanisms 7.

[0048] The side limiting box 803 is provided with a latch 804. The side limiting box 803 is also provided with an ejecting device, and the ejecting device is electrically connected to the control sensor 806. The latch 804 is adapted to the bayonet 707.

[0049] Through this technical solution, the latch 804 can be pushed out by the ejecting device. The ejecting device can receive the signal of the control sensor 806. When the connecting rod 701 is screwed to the installation position, the control sensor 806 reaches the preset value. At this time, the ejecting device ejects the latch 804 to catch the bayonet 707, thereby preventing the connecting rod 701 from being screwed in further.

[0050] The gripper 702 includes flexible claw fingers 704, a pneumatic component, and a fixing plate 703.

[0051] Through this technical solution, the gripper 702 on the grasping mechanism 7 can be set differently according to different electronic components to be measured as required. For some electronic components with high grasping requirements, flexible grippers can be selected to achieve markless grasping and avoid damage to the electronic components during the grasping process. For some electronic components with lower grasping requirements, a suction cup component with lower cost can be used.

[0052] The driving component is provided with guide posts and slide rails for guiding and limiting. The guide posts and slide rails limit the movement of the linear motor 10.

[0053] With this technical solution, the guide posts and slide rails are adapted to the linear motor 10, which is beneficial to the movement of the linear motor 10, helps save energy consumption, and can improve the movement stability of the linear motor 10 at the same time.

[0054] A magnetic grating reading head 11 is also provided on the driving assembly. The magnetic grating reading head 11 is arranged above the linear motor 10. A magnetic grating scale 2 is arranged on one side of the magnetic grating reading head 11. The bottom end of the magnetic grating scale 2 is fixedly connected to one side of the linear motor 10.

[0055] With this technical solution, when the linear motor 10 makes a lifting movement, it can drive the magnetic grating scale 2 to move. Through the mutual cooperation of the magnetic grating reading head 11 and the magnetic grating scale 2, the movement process of the linear motor can be accurately positioned.

[0056] Multiple groups of driving devices, connecting mechanisms 8 and grasping mechanisms 7 are arranged in an array, and the distance between adjacent groups of driving devices is set according to actual needs.

[0057] The material of the interface part 705 is selected as hard wear-resistant alloy.

[0058] With this technical solution, the wear of the interface part 705 can be reduced, so as to ensure the installation accuracy between the connecting rod 701 and the connecting sleeve 802.

[0059] A positioning device 4 is arranged on the second mounting bracket 3. The positioning device 4 is a positioning CCD camera, and a laser rangefinder is arranged below the positioning CCD camera.

[0060] With this technical solution, when the grasping mechanism 7 makes a lifting movement, the laser rangefinder arranged below the positioning CCD camera can measure the distance between the gripper 702 and the chip, simplifying the measurement operation of the distance between the gripper 702 and the grasped chip. At the same time, the distance measurement is more accurate, thereby improving the grasping accuracy of the gripper 702 and making the grasping and positioning of the gripper 702 more accurate.

[0061] Working principle: The top end of the buffer spring 6 is connected to the stable collar 801, and the bottom end of the buffer spring 6 is connected to the fixed block arranged on the limit fixing seat 5. The position of the buffer spring 6 itself is not blocked, which is convenient for disassembly and assembly. At the same time, the linear motor 10 and its moving components are not limited by the buffer spring 6, so that the device is easier to maintain in the later stage; at the same time, multiple types of grasping mechanisms 7 can be set according to the types of electronic components to be grasped. The grasping mechanism 7 is connected to the driving mechanism of the device through the connecting mechanism 8, and a detection chamber 805 is arranged on the connecting mechanism. A detection sensor 806 is arranged in the detection chamber 805. When the grasping mechanism 7 is installed in the correct position, the control sensor 806 reaches the preset value. At this time, the ejecting device ejects the retaining pin 804 to catch the bayonet 707, thereby preventing the connecting rod 701 from being screwed in again, which can reduce the correction and adjustment in the later stage of the installation of the grasping mechanism 7 and is convenient for expanding the application of different grasping mechanisms 7.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
