Description

Technical Field

[0001] The utility model belongs to the technical field of test equipment, and particularly relates to a multi-station FCT test equipment. Background Technique

[0002] Functional test (FCT) generally specifically refers to the test after the PCBA is powered on, mainly including test items such as voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, sound recognition, temperature measurement, pressure measurement, motion control, FLASH and EEPROM burning.

[0003] At present, most of the existing FCT test equipment is single-station test, and only one PCBA board can be tested at a time, so the test efficiency is relatively low.

[0004] The Chinese utility model patent with the publication number of CN220231804U discloses a multi-station FCT tester, which relates to the technical field of test and detection machinery, including a main frame body and a test module. An ion blower is installed inside the main frame body. The test modules are vertically arrayed at equal distances inside the main frame body, and auxiliary modules are horizontally installed on the left and right sides of the top of the test module. Moreover, a target board is horizontally and electrically connected to the center of the top of the test module. In this multi-station FCT tester, several test modules are erected at equal distances from bottom to top inside the main frame body, so that the whole device can respectively perform functional detection on multiple target boards, thereby improving the operation efficiency. And through the connection of the support columns, the auxiliary modules erected on the top of the test module can provide effective stable clamping effects for the target board from the left and right sides respectively in the horizontal direction, avoiding the interference of external factors on the target board during the test, and thus affecting the accuracy of the test results.

[0005] Although the technical solution disclosed in the above patent can perform multi-station tests, the position of the test module is not adjustable, which is not convenient for replacing the test module, and is not conducive to the mechanized loading and unloading operation of workpieces, and the test efficiency is still relatively low. Content of the Utility Model

[0006] In view of the above problems existing in the prior art, the purpose of the present utility model is to provide a multi-station FCT test equipment. The structural settings of the detachable upper mold and lower mold can improve the applicability of the equipment. By driving the lower mold to move out below the upper mold by a moving part, a feeding space is reserved, which is convenient for realizing the mechanized loading and unloading of workpieces and is beneficial to improving the test efficiency.

[0029] Embodiment 1

[0030] As Figure 1 , Figure 2 shown, the multi-station FCT test equipment includes a test mechanism 1, a transmission track 2, a machine frame 4, and a material transfer assembly 24. Among them, the test mechanism 1 is installed in the machine frame 4. The machine frame 4 is configured with a transmission track 2 for transporting workpieces and a material transfer assembly 24 for transferring workpieces. The material transfer assembly 24 is hoisted on the top of the machine frame 4 and includes a moving module and a material suction part. The material suction part is used for vacuum adsorbing workpieces and is driven by the moving module to move along the X-axis, Y-axis, and Z-axis to transfer workpieces. Among them, the main function of the material suction part is to vacuum adsorb workpieces to realize the transfer of workpieces. Its working principle is the prior art, and the structure is not limited here.

[0031] Specifically, the workpiece enters the test equipment through the transmission track 2. The material transfer assembly 24 adsorbs the workpiece on the transmission track 2 and then transfers it to the test mechanism 1 for functional testing. After the test is completed, the material transfer assembly 24 adsorbs the workpiece and transfers it to the transmission track 2, and the workpiece leaves the equipment through the transmission track 2.

[0032] Among them, please refer to Figure 2 emphatically. In order to achieve multi-station collaborative testing, the test mechanism 1 includes a support frame 6 loaded with a plurality of test modules 5. The support frame 6 includes at least two partition boards 601 and a plurality of support rods 602. The adjacent two partition boards 601 distributed up and down are connected by the support rods 602, and the partition boards 601 and the support rods 602 form a compartment for loading the test modules 5. Specifically, the material transfer assembly 24 adsorbs the workpiece on the transmission track 2 and sequentially transfers it to the test modules 5 in different compartments, and the test modules 5 test the workpiece.

[0033] As Figures 3 to 6As shown, the test module 5 includes a top plate 8, an upper mold 10, side plates 7 and a lower mold 11. The lower mold 11 includes a test station 14 for placing workpieces. The lower mold 11 is driven by a moving member 17 to reciprocate below the upper mold 10, facilitating the loading and unloading of the test station 14.

[0034] In this embodiment, two test stations 14 are provided on the lower mold 11, enabling one test module 5 to simultaneously test two workpieces. In addition, the number of test modules 5 is not limited. In this embodiment, 15 test modules 5 are configured. Specifically, the 15 test modules 5 are divided into 3 layers, with 5 test modules 5 configured in each layer. Since the compartments for loading the test modules 5 are composed of partition plates 601 and support rods 602, in order to reduce the number of partition plates 601 used, between adjacent compartments distributed vertically, the partition plate 601 serving as the bottom plate in the upper compartment serves as the upper plate in the lower compartment. The specific structure is as Figure 2 shown.

[0035] As Figure 3 , Figure 4 shown, the upper mold 10 is detachably connected to the top plate 8, facilitating the adjustment of the structure of the upper mold 10 according to the actual requirements of the workpiece. Specifically, a stop block 9, a fixed rod 15, an adjustment rod 16 and a clamping plate are installed on the top plate 8. The clamping plates are installed on both sides of the bottom of the top plate 8 for clamping the upper mold 10. The stop block 9 is installed between the two clamping plates for limiting the position of the upper mold 10. On one side of the top plate 8 relative to the stop block 9, a fixed rod 15 driven by the adjustment rod 16 to rotate is configured. A cylinder 12 is also configured beside the top plate 8. The top plate 8 is driven by the cylinder 12 to drive the upper mold 10 to move up and down. In addition, a guide rod 13 is configured beside the cylinder 12 to improve the stability of the up and down movement of the top plate 8 and the upper mold 10.

[0036] By rotating the fixed rod 15 through the adjustment rod 16, the upper mold 10 can be clamped to the top plate 8 through the clamping plate. Among them, the stop block 9 is used to limit the insertion position of the upper mold 10. When the upper mold 10 is in place, by rotating the fixed rod 15 through the adjustment rod 16, the fixed rod 15 abuts against the upper mold 10, fixing the upper mold 10 to the bottom of the top plate 8. By driving the top plate 8 to move up and down through the cylinder 12, the upper module 10 can be driven to move up and down.

[0037] As Figures 3 to 6As shown, the lower mold 11 is detachably connected to the side plates 7, facilitating the adjustment of the structure of the lower mold 11 according to the actual requirements of the workpiece. Specifically, there are two relatively arranged side plates 7, the side plates 7 are installed on the sliding plate 25, the sliding plate 25 is connected to the driving end of the moving member 17, a card slot for carrying the lower mold 11 is provided at the top of the side plates 7, a cylinder three 20 is installed inside the side plates 7, positioning holes 23 for the protruding end of the cylinder three 20 to insert are provided at corresponding positions of the side plates 7 and the lower mold 11. In addition, the test module 5 further includes a thimble 22 inserted into the lower mold 11, the thimble 22 is driven by a cylinder two 19 to move horizontally, a connecting plate 21 inserted with the thimble 22 is installed on one side of the lower mold 11 facing the thimble 22, and the cylinder two 19 is installed on the sliding plate 25.

[0038] Among them, the moving member 17 can be a module or an electric telescopic rod and other structures that can drive the lower mold 11 to move, which is not limited here. The moving member 17 is installed at the bottom of the lower partition 601 of the compartment where the test module 5 is located. The driving end of the moving member 17 is connected to the sliding plate 25 through a connecting member. A sliding groove for the connecting member to move is provided on the partition 601. A first slide rail 18 is also installed on the partition 601, and the sliding plate 25 is slidably connected to the first slide rail 18 to improve the stability of the lower mold 11 when moving.

[0039] Through the structures of the card slot on the side plates 7 and the lower mold 11, the side plates 7 are clamped with the lower mold 11. When the lower mold 11 moves to be inserted with the thimble 22, it means that the lower mold 11 is in place. At this time, the cylinder three 20 is started, so that the protruding end of the cylinder three 20 is inserted into the positioning hole 23 to fix the lower mold 11 on the side plates 7.

[0040] Embodiment 2

[0041] As Figures 7 to 9 shown, the structure of this embodiment is basically the same as that in Embodiment 1, and the difference lies in that: in this embodiment, the transmission track 2 includes a guide rail one 201 and a guide rail two 202 with adjustable spacing. Among them, the principle of the transmission track 2 for transmitting workpieces is the prior art and will not be elaborated here. It should be noted that in order to adapt to workpieces of different specifications, the spacing between the guide rail one 201 and the guide rail two 202 is adjustable. The driving end of the motor 203 and the lead screw 204 are connected through a synchronous belt, so that the motor 203 can drive the lead screw 204 to rotate, and the slider 205 can drive the guide rail one 201 or the guide rail two 202 to move on the lead screw 204, thereby adjusting the spacing between the guide rail one 201 and the guide rail two 202. In addition, a second slide rail 206 and a slide rod that cooperate with the slider 205 are also installed between the guide rail one 201 and the guide rail two 202. The slider 205 is slidably connected to the second slide rail 206 and the slide rod respectively, as Figure 9As shown, both ends of the second slide rail 206, the slide rod, and the lead screw 204 are respectively connected to the support plate, and the support plate mounts the second slide rail 206, the slide rod, and the lead screw 204 between the first guide rail 201 and the second guide rail 202.

[0042] Embodiment Three

[0043] As Figures 1 to 9 shown, the structure of this embodiment is basically the same as that in Embodiment One. The difference lies in that: in this embodiment, the test module 5 serves as a power-on test mechanism to perform a power-on test on the workpiece to determine whether the workpiece can be powered on. And at the terminal of the transfer track 2, a second test mechanism 3 is mounted through a fixing bracket 303. The second test mechanism 3 includes a test mold 302 that moves up and down driven by an electric cylinder 301. A blocking cylinder is installed at the position on the transfer track 2 corresponding to the test mold 302. Among them, the structure of the test mold 302 is similar to that of the test module 5, including an upper mold and a lower mold. The lower mold is located between the first guide rail 201 and the second guide rail 202 of the transfer track 2, and the upper mold is driven by the electric cylinder 301 to move up and down. The test mold 302 serves as a functional test mechanism.

[0044] Since functional testing requires testing the voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, sound recognition, temperature measurement, pressure measurement, motion control, FLASH and EEPROM programming, etc. of the powered-on circuit board, and there may be cases where the circuit board cannot be powered on, it is necessary to perform a power-on test before functional testing and mark the circuit boards that cannot be powered on in advance, which is beneficial to improving the efficiency of subsequent functional testing.

[0045] Specifically, the test module 5 performs a power-on test on the workpiece, marks the workpieces that fail the test, and then the moving component 23 transfers the tested workpieces to the transfer track 2 to flow through the test mold 302. At this time, the test mold 302 does not perform functional testing on the marked workpieces, and the unqualified workpieces directly flow away through the transfer track 2 and enter the screening mechanism (not shown in the figure) to be removed. When the unmarked workpieces pass through the test mold 302, the blocking cylinder will prevent the qualified workpieces from moving, so that the test mold 302 performs functional testing on them.

[0046] Without changing the transportation path of the workpiece, by first performing a power-on test through the test module 5 and marking the unqualified workpieces, so that the unqualified workpieces no longer undergo the functional testing of the test mold 302, the testing efficiency of the entire testing production line can be effectively improved.

[0047] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded 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 utility model shall be included within the protection scope of the present utility model.
