Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductor testing, and particularly relates to a multi-station high-efficiency testing device.

Background Art

[0002] With the development of electronic technology and the continuous increase in the demand for electronic devices by consumers, it is required that the testing of semiconductor components has high production efficiency to meet the requirements of large-scale production. Since the size of semiconductor components is small, generally multiple components are arranged and stored in a cartridge. When testing, it is necessary to complete the automatic feeding and automatic testing of the semiconductor components in the cartridge. However, the general automation level is not high, the functions are single, and the number of stations is small, resulting in low production efficiency and waste of manpower and material resources. For example, the four-station automatic programming device disclosed in Chinese Patent Publication No. CN106201637B, including a loading mechanism, a cartridge flipping mechanism, a feeding track, a first sorting mechanism, a second sorting mechanism, a first programming mechanism, a second programming mechanism, and a receiving mechanism. This solution can achieve cartridge flipping and testing, but there are still the following two problems:

[0003] (1) If it is necessary to test components under heating conditions, this testing device cannot complete the test.

[0004] (2) In this solution, both the first programming mechanism and the second programming mechanism are provided with four testing channels. However, only one cartridge flipping mechanism is provided in this solution, and the components in one cartridge enter the testing channels of the programming mechanism in sequence, resulting in low feeding efficiency and slow beat.

[0005] Therefore, it is necessary to provide a multi-station high-efficiency testing device to solve the above technical problems.

Detailed implementation manner

[0042] Please refer to Figures 1-11 , this embodiment is a multi-station high-efficiency testing device. The multi-station high-efficiency testing device 100 includes a frame 1, a tube feeding mechanism 2 arranged above the frame 1, a plurality of tube flipping mechanisms 3 arranged side by side with the tube feeding mechanism 2, a tube conveying device 4 that conveys the tubes on the tube feeding mechanism 2 to the tube flipping mechanisms 3, a vertically arranged conveying pipeline 5 that is correspondingly connected to the end of the tube flipping mechanism 3, a first material control mechanism 6 arranged at the upper end of the conveying pipeline 5 to control the downward conveyance of the components in the tube 200, a heating device 9 arranged on the outer periphery of the middle part of the conveying pipeline 5, a second material control mechanism 7 arranged at the lower end of the conveying pipeline 5 and inside the heating device 9, a plurality of testing devices 8 arranged at the lower end of the heating device 9 to test the components, a receiving device 10 arranged at the end of the conveying pipeline 5 to receive the components after testing, and a transfer device 20 used to transfer the components in the conveying pipeline 5 into the receiving device 10.

[0043] The material pipe feeding mechanism 2 includes two storage racks arranged oppositely, and multiple material pipes 200 are horizontally stacked on the storage racks along the Y direction.

[0044] The material pipe handling device 4 is located below the material pipe feeding mechanism 2. The material pipe handling device 4 includes a first linear driving module 41 arranged on the frame 1, a first cylinder driven by the first linear driving module 41 to move along the X direction, and a first material pushing block driven by the first cylinder to move up and down. Under the driving action of the first linear driving module 41 and the first cylinder, the first material pushing block transports the material pipes on the material pipe feeding mechanism 2 to several material pipe flipping mechanisms 3 respectively, and a first avoidance opening for avoiding the movement of the first material pushing block is arranged on the frame 1.

[0045] In this embodiment, the material pipe flipping mechanisms 3, the conveying pipelines 5 and the testing devices 8 are in one-to-one correspondence, and there are four of each. A testing device 8 is arranged at the lower end of each conveying pipeline 5. The material pipe flipping mechanisms 3 respectively transport the components to the lower ends of the corresponding conveying pipelines 5, and each testing device 8 completes the testing of the corresponding components. In other embodiments, the specific numbers of the material pipe flipping mechanisms 3, the conveying pipelines 5 and the testing devices 8 can be set to multiple, which can be determined according to actual situations and are not limited.

[0046] Multiple material pipe flipping mechanisms 3 are arranged side by side along the X direction above the frame 1. The material pipe flipping mechanism 3 includes a flipping shaft 31 fixed on the frame 1, a first support plate 32 rotatably arranged on the flipping shaft 31, a receiving plate 35 arranged at the bottom end of the first support plate 32 for placing the material pipe 200, a clamping assembly 33 arranged on the first support plate 32 for clamping the bottom end of the material pipe, a flipping driving member for pushing the first support plate 32 to rotate so as to change the material pipe 200 from a horizontal state to a vertical state, and an arc-shaped blocking block 34 arranged on the first support plate 32 for blocking the components at the bottom end of the material pipe 200 from falling down when the material pipe is flipped.

[0047] The clamping assembly 33 includes a second cylinder 331 fixed on the first support plate 32 and an adsorption clamping block 332 driven by the second cylinder 331 to move up and down. A clamping groove 333 imitating the shape of the material pipe 200 is arranged at the bottom end of the adsorption clamping block 332, and adsorption holes are arranged in the clamping groove 333. When the material pipe handling device 4 transports the material pipe to the receiving plate 35, the second cylinder 331 drives the adsorption clamping block 332 to clamp the material pipe and evacuates the inside of the adsorption clamping block 332 to vacuum, so as to clamp one end of the material pipe 200.

[0048] An impact assembly 36 for impacting the material pipe 200 to enable the components inside the material pipe to smoothly enter the conveying pipeline 5 is further arranged above the clamping assembly 33. When the flipping driving member drives the first support plate 32 to drive the material pipe to change from a horizontal state to a vertical state, the impact assembly 36 extends out to impact the outer periphery of the material pipe 200, so as to enable the components inside the material pipe to smoothly enter the conveying pipeline 5.

[0049] The cross-sectional shape of the conveying pipe 5 is set to be shaped according to the size of the components, so as to facilitate the sequential single conveyance of the components in the conveying pipe 5, and problems such as stacking and misalignment will not occur. A plurality of conveying pipes 5 are vertically arranged on the frame 1, and the heating device 9 is arranged outside the conveying pipe 5. The heating device 9 includes a heating cavity 91 arranged around a plurality of conveying pipes 5, a heating module 92 arranged inside the heating cavity 91 and surrounding the outer circumference of each conveying pipe 5, and a closed cover 93 covering the heating cavity 91. The components in the waiting material pipe 200 enter the conveying pipe 5, and the second material control mechanism 7 restricts the downward conveyance of the components. At this time, the conveying pipe 5 is filled with components and is located in the heating cavity 91, and the conveying pipe 5 is heated by the heating module 92 to complete the heating of the components.

[0050] The first material control mechanism 6 includes a first baffle 61 that blocks the components in the material pipe 2 from entering the conveying pipe 5 and a third air cylinder 62 that drives the first baffle 61 to extend into the conveying pipe 5 to block the downward conveyance of the components.

[0051] The second material control mechanism 7 includes a first stop rod 71 that blocks the first component at the bottom of the conveying pipe 5, a second stop rod 72 that blocks the second component at the bottom of the conveying pipe 5 and is located above the first stop rod 71, and a blocking driving member 73 that drives the first stop rod 71 and the second stop rod 72 to alternately extend to block the components. Sensors for detecting materials are arranged on the sides of both the first material control mechanism 6 and the second material control mechanism 7.

[0052] The testing device 8 includes a testing probe 81, a probe mounting plate 82 for fixing the testing probe 81, a stop rod 84 mounted on the probe mounting plate 82 and used to stop the components, and a fourth air cylinder 83 that simultaneously drives the stop rod 84 and the testing probe 81 to contact the components. After the components are conveyed in place, the fourth air cylinder 83 drives the probe mounting plate 82 to move towards the component side. At this time, the stop rod 84 presses against the surface of the component to stop the component, and at the same time, the testing probe 81 contacts the pins of the component. After the contact is conducted, relevant tests can be completed. Since the stop rod 84 presses against the surface of the component during testing, there is a certain pressure on the conveying pipe 5. In order to prevent the conveying pipe 5 from deforming and affecting the conveyance of the components, a pressing component is arranged on the back of the conveying pipe 5. The pressing component includes a pressing plate 85 that presses against the back of the conveying pipe 5 and a fifth air cylinder 86 that drives the pressing plate 85 to contact or move away from the conveying pipe 5.

[0053] The receiving device 10 is inclinedly arranged on the frame 1. In order to facilitate the smooth entry of the materials in the conveying pipe 5 into the receiving device 10, the lower end tail of the conveying pipe 5 is bent to form an arc transition, so that the components can smoothly enter the receiving device 10.

[0054] The receiving device 10 includes a qualified product receiving device 101 and a defective product receiving device 102. The defective product receiving device 102 includes several empty material tubes, a mounting block 1021 for fixing the empty material tubes, and a waste receiving tank 1022 arranged below the empty material tubes. There are two groups of qualified product receiving devices 101, which can receive materials alternately, reducing the feeding frequency and improving production efficiency.

[0055] The qualified product receiving device 101 includes a material tube rack 1011 for storing multiple empty material tubes, a receiving bin 1012 for storing multiple material tubes containing components, a tube transfer mechanism 1013 for transporting the empty material tubes on the material tube rack 1011 to the bottom of the receiving bin 1012, a material receiving module 1014 for receiving the components after the test is completed, a diversion channel 1015 arranged at the upper end of the receiving bin 1012 and used to divert the components in the conveying pipeline 5 onto the material receiving module 1014, and a pushing component 1016 for pushing the material tubes filled with components on the material receiving module 1014 onto the receiving bin 1012.

[0056] Support platforms for supporting the material tubes are arranged at the bottoms of both ends of the material tube rack 1011 and the receiving bin 1012, and a transfer gap for a single material tube to pass through is arranged between the material tube rack 1011 and the receiving bin 1012.

[0057] The tube transfer mechanism 1013 includes a second linear driving module 10131 arranged on the frame 1, a sixth cylinder 10132 driven by the second linear driving module 10131 to move along the X direction, and a second dialing block 10133 driven by the sixth cylinder 10132 to move up and down.

[0058] The material receiving module 1014 includes a seventh cylinder 1018 arranged at the lower end of the support platform and used to drive the empty material tube 200 to move up and down to be connected or disconnected from the diversion channel 1015.

[0059] The pushing component 1016 includes a pushing plate 10161 for pushing the material tube and an eighth cylinder 10162 for driving the pushing plate 10161 to move upward. A blocking block for blocking the bottommost material tube is rotatably arranged at the bottom of the receiving bin 1012.

[0060] There are four conveying pipelines 5. In order to improve the receiving efficiency, there are two groups of qualified product receiving devices 101, which are arranged vertically offset. Therefore, a transfer device 20 is arranged between the conveying pipeline 5 and the qualified product receiving device 101.

[0061] The transfer device 20 includes a transfer cassette 201 for receiving the components after the test is completed and a conveyor line 202 for driving the transfer cassette 201 to move in the X direction. Two flow channels 203 for the components to pass through are provided inside the transfer cassette 201, and a material control assembly for controlling the downward fall of the components is provided at the lower end of each flow channel 203. The material control assembly includes a third stop rod 204 extending into the flow channel 203 and a ninth cylinder 205 for driving the third stop rod 204 to extend into the flow channel 103. When the conveyor line 202 drives the transfer cassette 201 to move, the upper end of the transfer cassette 201 can be in contact and communicate with the conveying pipeline 5 to receive the components after the test is completed. When the conveyor line 202 drives the transfer cassette 201 to move again, the lower end of the transfer cassette 201 can communicate with the diversion channel 1015 to allow the components to flow into the material pipe of the receiving module 1014.

[0062] When applying a multi-station high-efficiency testing device 100 provided by this solution, an operator or a manipulator places multiple material pipes 200 filled with components on the material pipe feeding mechanism 2 to stack them up. When the first dialing block transports the material pipes on the material pipe feeding mechanism 2 to the receiving plates 35 of several material pipe flipping mechanisms 3 under the driving action of the first linear driving module 41 and the first cylinder, the second cylinder 331 drives the adsorption clamping block 332 to clamp the material pipe and simultaneously evacuates the inside of the adsorption clamping block 332, so as to clamp one end of the material pipe 200. When the flipping driving member drives the first support plate 32 to drive the material pipe to change from the horizontal state to the vertical state, the third cylinder 62 drives the first baffle 61 to retract, so that the components fall into the conveying pipeline 5 from the material pipe, and the lowest component in the conveying pipeline 5 is blocked by the first stop rod 71 of the second material control mechanism 7. When the conveying pipeline 5 is filled with components, the third cylinder 62 drives the first baffle 61 to extend to block the components from falling into the conveying pipeline 5 from the material pipe 200. The heating device 9 is turned on to heat the components in the conveying pipeline 5. After the heating is completed, the second stop rod 72 of the second material control mechanism 7 extends to block the second lowest component, and the first stop rod 71 retracts to allow the lowest component to be conveyed downward into the testing device 8. The fourth cylinder 83 drives the stop rod 84 to stop the component and at the same time the test probe 81 contacts the pins of the component to conduct the test. After the test is completed, the fourth cylinder 83 drives the stop rod 84 and the test probe 81 to retract, allowing the component to continue to be conveyed downward to the end of the conveying pipeline. The conveyor line 202 drives the transfer cassette 201 to sequentially receive the components after the test is completed. After the transfer cassette 201 is filled with components, the conveyor line 202 drives the transfer cassette 201 to communicate with the diversion channel 1015, and the components are conveyed to the material pipe 200 on the receiving module 1014 through the diversion channel 1015. After the material pipe 200 is filled with components, the pushing assembly 1016 pushes the material pipe filled with components upward and stacks it in the receiving bin 1012. At the same time, the pipe moving mechanism 1013 moves the empty material pipe on the material pipe rack 1011 to the receiving module 1014 to continue receiving the components after the test is completed.

[0063] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
