[0067] Please refer to Figure 1-Figure 3 The embodiment of the present application provides a test device for PCBA and EOL finished products, including a bracket 100, a test fixture 200, a locking member 300 and a locking drive member 400.
[0068] The bracket 100 is used to provide a mounting reference for the test fixture 200 .
[0069] The test fixture 200 has a test station 200a for testing a product. It is understandable that the test station 200a can test a PCBA board or perform an EOL (End-of-Life) test to determine whether it is qualified.
[0070] The locking member 300 has a locked state and an unlocked state. In the locked state, the test fixture 200 is locked and connected to the bracket 100. At this time, the test fixture 200 is fixed on the bracket 100, and the test station 200a is relatively fixed, so that the external manipulator 30 can transport the product to the test station 200a, or remove the product from the test station 200a. In the unlocked state, the test fixture 200 can be separated from the bracket 100, so as to facilitate the operator or automatic machine equipment to move and replace the test fixture 200. It can be understood that the test fixture 200 and the bracket 100 are detachably connected through the locking member 300.
[0071] The locking driver 400 is used to drive the locking member 300 to switch between a locked state and an unlocked state. That is, when the test fixture 200 needs to be replaced, the locking driver 400 can drive the locking member 300 to enter the unlocked state, so as to facilitate the operator or the automatic machine equipment to replace the test fixture 200. The new test fixture 200 can be moved to the corresponding position of the bracket 100 by the operator or the automatic machine equipment, and the locking driver 400 drives the locking member 300 to enter the locked state, thereby fixing the new test fixture 200 on the bracket 100.
[0072] In the above embodiment, the locking driver 400 can drive the locking member 300 to lock and connect the test fixture 200 to the bracket 100, or drive the locking member 300 to separate the test fixture 200 from the bracket 100. When the test fixture 200 needs to be replaced, the locking driver 400 can drive the locking member 300 to enter an unlocked state to facilitate the operator or automatic machine equipment to replace the test fixture 200. The new test fixture 200 can be moved to the corresponding position of the bracket 100 by the operator or the automatic machine equipment, and the locking driver 400 drives the locking member 300 to enter a locked state, thereby fixing the new test fixture 200 on the bracket 100. Since the above-mentioned unlocking and locking control is realized by the locking driver 400, the efficiency of replacing the test fixture 200 can be improved, and it is convenient to realize automatic control and can be applied to the fully automatic test equipment 1.
[0073] The locking driver 400 may be a cylinder, a hydraulic cylinder or a motor. In some embodiments, the locking driver 400 is a cylinder, which may be driven and controlled by a programmable controller.
[0074] In some embodiments, the bracket 100 includes a movable member 110 and a fixed member 120. The movable member 110 can move relative to the fixed member 120.
[0075] The test fixture 200 includes a first test fixture 210 and a second test fixture 220. The first test fixture 210 and the second test fixture 220 are arranged opposite to each other along a first direction. The first test fixture 210 and the second test fixture 220 can test the product in a matching state. Figure 2 , the first direction is the up-down direction.
[0076] The locking member 300 includes a first locking member 310 and a second locking member 320. The first locking member 310 can lock and connect the first test fixture 210 and the movable member 110 in a locked state, so that the first test fixture 210 moves with the movable member 110. It can be understood that in an unlocked state, the first test fixture 210 and the movable member 110 can be separated. The second locking member 320 can lock and connect the second test fixture 220 and the fixed member 120 in a locked state, so that the second test fixture 220 is fixed to the fixed member 120. Similarly, in an unlocked state, the second test fixture 220 and the fixed member 120 can be separated.
[0077] The test device 10 further includes a fixture driving assembly 500, which drives the first test fixture 210 to move along a first direction and to mate with the second test fixture 220, or drives the first test fixture 210 to move in a reverse direction and to separate from the second test fixture 220. In the mate state, the product between the first test fixture 210 and the second test fixture 220 can be tested. In the detached state, the tested product can be removed, and the product to be tested can be sent between the first test fixture 210 and the second test fixture 220.
[0078] In order to facilitate the replacement of the first test fixture 210 and the second test fixture 220, in some embodiments, when the first test fixture 210 and the second test fixture 220 are combined, the first locking member 310 is unlocked and the second locking member 320 is unlocked. At this time, the first locking member 310 and the second locking member 320 can be transferred as a whole at one time.
[0079] The specific structures of the fixed member 120 and the movable member 110 are not limited. In some embodiments, the fixed member 120 includes an upper plate 121, a lower plate 122, and a plurality of connecting shafts 123 connecting the upper plate 121 and the lower plate 122, and the movable member 110 is a movable plate, which is arranged parallel to the lower plate 122, and the movable plate can be moved along the length direction of the connecting shaft 123 to adjust the spacing between the movable plate and the lower plate 122.
[0080] A guide sleeve 111 may be provided on the movable plate body, and the guide sleeve 111 is sleeved on the connecting shaft 123 and can slide.
[0081] In some embodiments, the locking driver 400 includes a first locking driver 410, and the first locking driver 410 is disposed on the movable member 110 to move with the movable member 110. The first locking driver 410 may be a cylinder.
[0082] The first locking member 310 includes a push block 311 and a clamp block 312. The push block 311 is drivingly connected to the first locking driver 410, and the clamp block 312 is connected to the first test fixture 210. The clamp block 312 has a clamping slot. In the driving direction of the first locking driver 410, the clamping slot is opposite to the push block 311.
[0083] The first locking driving member 410 can push the push block 311 into the slot so that the first test fixture 210 is locked and connected to the movable member 110, or push the push block 311 to exit the slot in the opposite direction so that the first test fixture 210 can be separated from the movable member 110. Since the driving action of the first locking driving member 410 can be automatically controlled, the unlocking state and the locking state of the first test fixture 210 and the movable member 110 can be automatically switched, which is convenient for realizing the automatic replacement of the first test fixture 210 when adjusting the product.
[0084] In order to improve the reliability of the connection between the first test fixture 210 and the movable member 110 in the locked state. In some embodiments, the first locking driver 410 and the push block 311 are located on the first surface of the movable member 110, the first test fixture 210 and the block 312 are located on the opposite second surface of the movable member 110, and the block 312 partially extends and protrudes from the first surface of the movable member 110;
[0085] The slot is located at the portion of the block 312 protruding from the first surface, at least part of the top surface of the push block 311 is a wedge-shaped surface, the slot has opposing wedge-shaped surfaces, the push block 311 is inserted into the slot, and the two wedge-shaped surfaces cooperate to lock the first test fixture 210 on the movable part 110. Similarly, when the push block 311 is withdrawn from the slot, the two wedge-shaped surfaces slide relative to each other and separate, and the first test fixture 210 is unlocked and separated from the movable part 110.
[0086] It is understandable that even if the first locking driver 410 is damaged, since the direction of gravity is perpendicular to the driving direction of the first locking driver 410 , the first test fixture 210 and the movable member 110 can still maintain a locked state, and the reliability is good.
[0087] The movable member 110 may be provided with a through channel, and the block 312 may extend into the through channel and partially extend out.
[0088] Driven by the first locking driving member 410 , the locking block 312 can move relative to the movable member 110 .
[0089] The number of the first locking drive member 410 and the first locking member 310 is not limited and can be one or more. In some embodiments, two first locking drive members 410 are provided, and the two first locking drive members 410 are arranged opposite to each other and spaced apart, and the connection position between the fixture drive assembly 500 and the movable member 110 is between the two first locking drive members 410. The two first locking drive members 410 drive the block 312 in opposite directions.
[0090] In some embodiments, the locking driver 400 includes a second locking driver 420, and the second locking driver 420 is disposed on the fixing member 120. The second locking driver 420 may be a cylinder.
[0091] The second locking member 320 includes a supporting block 321 and a limiting block 322. The supporting block 321 is drivingly connected to the second locking driver 420, and the limiting block 322 is connected to the fixing member 120. The supporting block 321 and the limiting block 322 are arranged opposite to each other, and the second locking driver 420 can drive the supporting block 321 to move toward the limiting block 322 or move away from the limiting block 322.
[0092] The fixing member 120 has a mounting position for mounting the second test fixture 220, and the second locking driver 420 drives the supporting block 321 to support and push the second test fixture 220 to move to the mounting position. In the locked state, the second test fixture 220 in the mounting position is clamped and locked by the supporting block 321 and the limiting block 322. It can be understood that the supporting block 321 and the limiting block 322 are respectively located on opposite sides of the mounting position, and under the drive of the second locking driver 420, the supporting block 321 moves toward the limiting block 322, thereby clamping and fixing the second test fixture 220. Since the driving action of the second locking driver 420 can be automatically controlled, the unlocking state and the locking state of the second test fixture 220 and the fixing member 120 can be automatically switched, which is convenient for realizing the automatic replacement of the second test fixture 220 when the product is adjusted.
[0093] There is no limitation on the connection method between the limit block 322 and the fixing member 120 . For example, the limit block 322 can be fixed to the fixing member 120 by a fastener.
[0094] It is understandable that the test fixture 200 has a connection port, which is used to connect to the test instrument signal, so as to transmit the test signal to the test instrument for processing. When replacing the test fixture 200, the test instrument needs to be disconnected from the connection port.
[0095] In order to improve the replacement efficiency. In some embodiments, the test device 10 includes a test plug 710 and a plug-in drive 720, the plug-in drive 720 drives the test plug 710 to connect, the test fixture 200 has a connection port, and the plug-in drive 720 can drive the test plug 710 to connect to the connection port, or drive the test plug 710 to separate from the connection port. Among them, the plug-in drive 720 can be a cylinder.
[0096] In some embodiments, the plug-in drive member 720 is fixed to the fixing member 120 , the plug-in drive member 720 is located between the two second locking drive members 420 , and the driving direction of the plug-in drive member 720 is the same as the driving direction of the two second locking drive members 420 .
[0097] In order to facilitate the test fixture 200 to enter the installation position, in some embodiments, guide members 730 are provided on opposite sides of the installation position, and the guide members 730 have a plurality of guide rollers. The plurality of guide rollers of the two guide members 730 are provided in a bell-shaped shape as a whole.
[0098] It can be understood that when the second test fixture 220 is in the installation position, the first test fixture 210 can be aligned with the second test fixture 220 .
[0099] In order to ensure that the second test fixture 220 can be accurately located at the installation position, in some embodiments, the test device 10 includes a positioning assembly 600 .
[0100] The positioning assembly 600 includes a first positioning drive member 610, a first positioning block 620 and a second positioning block. The first positioning drive member 610 is arranged on the fixing member 120, the first positioning block 620 is driven and connected to the first positioning drive member 610, and the second positioning block is connected to the fixing member 120. The first positioning drive member 610 drives the first positioning block 620 to hold and push the second test fixture 220 to move to the second positioning block.
[0101] The first positioning driver 610 and the second positioning block are arranged on opposite sides of the installation position along the second direction, the second locking driver 420 and the limit block 322 are arranged on opposite sides of the installation position along the third direction, and the second direction and the third direction are arranged vertically and are both perpendicular to the first direction. The first positioning driver 610 can be a cylinder.
[0102] It is understandable that the first positioning driver 610 and the first positioning block 620 are on one side of the installation position, and the second positioning block is on the other side opposite thereto. By driving the first positioning driver 610 to drive the first positioning block 620 to hold and push the second test fixture 220 to move to the second positioning block, the positioning of the second test fixture 220 along the second direction can be achieved. By driving the second locking driver 420 to hold the holding block 321 to hold and push the second test fixture 220 to move to the limit block 322, the positioning of the second test fixture 220 along the third direction can be achieved. Since the third direction is perpendicular to the second direction, the second test fixture 220 can be positioned in the above-mentioned installation position. The above-mentioned positioning process is realized by driving the first positioning driver 610 and the second locking driver 420, so it is convenient to realize the automatic positioning of the second test fixture 220 when the product is adjusted.
[0103] Please refer to Figure 5-Figure 9 The embodiment of the present application also provides a testing device, which includes a rack, a power distribution cabinet, a feed conveyor line 20, a testing device 10 and a manipulator 30.
[0104] Please refer to Figure 5 and Figure 6 The feeding conveyor line 20 is used to convey the product to the testing device 1, and the feeding conveyor line 20 has a material taking station. The manipulator 30 can take the product from the material taking station.
[0105] The robot arm 30 can take the product from the material taking station and transport it to the testing station 200a of the testing device 10 to test the product.
[0106] The number of the testing device 10 is at least one. Specifically, the testing process of the testing device 10 takes a certain amount of time. In order to improve efficiency, multiple testing devices 10 can be set, so that the manipulator 30 puts the product into the testing stations 200a of the multiple testing devices 10, and takes out the tested product from the testing station 200a. In this way, the automation of feeding, testing, and discharging is realized.
