Description

Technical Field

[0001] This utility model relates to the field of electronic component testing technology, and in particular to an electronic component fixing device for testing equipment. Background Technology

[0002] Electronic equipment refers to devices composed of electronic components such as integrated circuits, transistors, and vacuum tubes, which utilize electronic technology, including software, to function. These include electronic computers and computer-controlled robots, numerical control or programmable control systems, etc. However, existing electronic components lack adequate testing equipment during use, making it inconvenient for users to use and operate them effectively, thus preventing users from achieving good testing results.

[0003] According to Chinese Patent No. CN222337242U, a fixing device for performance testing of electronic components is disclosed. The device includes a test platform with an operating table on top. Several electronic component placement slots are provided on the top of the operating table. Two insertion slots are provided on the inner wall of each electronic component placement slot. A metal rod is provided on the upper side of each insertion slot. When the push rod of an electric push rod extends, a second horizontal plate drives multiple connecting brackets to move downward, so that the metal rod is inserted into the insertion slot and contacts the pins of the electronic component, thereby performing performance testing on the electronic component. Under the action of a tension spring, the metal rod has a certain buffer when contacting the pins of the electronic component, avoiding damage to the pins that may be caused by hard contact. The operator only needs to press a switch to achieve automatic contact between the metal rod and the pins of the electronic component, without manual operation, thus greatly improving work efficiency.

[0004] As can be seen from the above structure, although the structure can perform limit testing on components, it is particularly inconvenient when collecting components after testing, thus reducing the practicality of the device. In addition, in the traditional process of electronic component performance testing, the fixing of electronic components is often achieved by manual operation or simple mechanical structure. During the positioning process, manual assistance is required. Furthermore, existing testing equipment usually replaces the next component after testing, thus reducing the testing efficiency of electronic components. Utility Model Content

[0005] To address the aforementioned issues, this invention aims to propose an electronic component fixing device for testing equipment. By combining continuous conveying with automated unloading, it enables unmanned assembly line testing and reduces the cost of manual intervention.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An electronic component fixing device for a testing device, comprising:

[0008] Workbench;

[0009] The closed-loop conveying assembly, located above the workbench, includes a parallel conveyor frame, a synchronous roller rotatably connected to the conveyor frame, a synchronous belt sleeved on the synchronous roller, and a synchronous motor that drives the synchronous roller.

[0010] Multiple mounting components are equidistantly distributed along the surface of the synchronous belt, and each mounting component is connected to a component fixing mold by a detachable snap-fit ​​structure;

[0011] The test assembly mounted above the conveying assembly includes a support frame, an electric actuator vertically mounted on the support frame, and a test plate driven by the electric actuator. The bottom of the test plate is provided with an array of test probes.

[0012] The unloading assembly, located at the end of the conveying path, includes an adjustable gripper mechanism;

[0013] And a negative pressure adsorption fixing mechanism located at the bottom of the workbench.

[0014] Furthermore, the unloading assembly includes an unloading frame set on the upper part of the workbench, an unloading rod extending vertically on the unloading frame, an adjustment groove with a telescopic cylinder inside the unloading rod, and an electric gripper with force feedback function connected to the end of the telescopic cylinder.

[0015] Furthermore, the mounting assembly includes multiple snap-fit ​​frames disposed on the surface of the timing belt. Each snap-fit ​​frame has snap-fit ​​holes on both sides. A snap-fit ​​block is fixedly connected to the lower end of the fixing mold. Each snap-fit ​​block has a circular groove on both sides. A snap-fit ​​spring is fixedly connected inside the circular groove. A snap-fit ​​connector is fixedly connected to the other end of the snap-fit ​​spring. The snap-fit ​​connector engages with the snap-fit ​​holes.

[0016] Furthermore, the fixed mold includes a mold base, the upper end of which has a component slot, and both sides of the component slot have lead wire slots. The upper end of the mold base has a test slot inside the lead wire slot, and both sides of the upper end of the mold base have clamping slots. Magnet blocks are provided inside the component slot and the lead wire slot.

[0017] Furthermore, the negative pressure adsorption fixing mechanism includes a housing fixedly connected to the lower end of the workbench, an electric push rod fixedly connected inside the housing, and a rubber pad suction cup fixedly connected to the other end of the electric push rod.

[0018] Furthermore, the conveying assembly also includes a guide support system located inside the synchronous belt.

[0019] Furthermore, the guiding support system includes a support plate fixedly connected to one side of the conveying component, and a support plate fixedly connected to the inner side of each support plate. There are two support plates, and each support plate is slidably connected to the inner side of the timing belt.

[0020] Furthermore, the upper end of the bracket is slidably inserted into the upper end of the test plate, and limit rods are fixedly connected to both sides of the upper end of the test plate. Limit holes are opened on the upper end of the bracket, and the limit rods and limit holes are inserted into each other.

[0021] Beneficial effects: First, this utility model, through the setting of a conveying component and a fixed mold, allows for the following process: the fixed mold adapted to the component is installed on the upper end of the conveying component, and then the component is placed inside the component slot, with the component pins entering the lead slot. Both the component slot and the lead slot are equipped with magnets, which enable the electronic component to be magnetically attracted. Then, the conveying motor starts and drives the synchronous belt to move, so that the synchronous belt stops after moving to the test position. The test probe moves downward and inserts into the test slot, making contact with the component pin, thereby achieving the test effect. At the same time, the conveying component can achieve a cyclic test effect, increasing the testing efficiency of electronic components.

[0022] Secondly, this utility model, through its installation components, allows for the replacement of fixed molds when testing different electronic components. Replacing the fixed mold with a matching one involves inserting a snap-fit ​​block into the snap-fit ​​frame. During insertion, the snap-fit ​​connector is compressed into the circular groove. After the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the snap-fit ​​hole aligns with the circular groove. At this point, the snap-fit ​​connector pops out of the groove under the action of the snap-fit ​​spring, allowing it to snap into the snap-fit ​​hole, thus achieving the snap-fit ​​effect. This enables the installation of matching fixed molds, making the device suitable for testing different electronic components.

[0023] Third, the feeding assembly allows for component testing via test probes. After testing, the signal is transmitted to the control equipment, which records the number of drive steps. The control equipment then controls the feeding assembly. Components that pass the test are fed into the good feeding station of the feeding assembly by an electric gripper, while components that fail the test are fed into the scrap feeding station by an electric gripper. This facilitates efficient feeding of electronic components and, through automation, reduces labor costs while increasing testing efficiency. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Example 1

[0032] See Figure 1-4 A device for fixing electronic components in a testing apparatus, comprising:

[0033] Workbench 1;

[0034] The closed-loop conveying assembly 2, which is set above the workbench 1, includes a conveying frame 21 arranged in parallel, a synchronous roller 22 rotatably connected to the conveying frame 21, a synchronous belt 23 sleeved on the synchronous roller 22, and a synchronous motor 24 that drives the synchronous roller 22.

[0035] Multiple mounting components 3 are equidistantly distributed along the surface of the synchronous belt 23, and each mounting component 3 is connected to a component fixing mold 4 by a detachable snap-fit ​​structure;

[0036] The test assembly mounted above the conveying assembly 2 includes a support frame 6, an electric push rod 8 vertically mounted on the support frame 6, and a test plate 9 driven by the electric push rod 8. The bottom of the test plate 9 is provided with an array of test probes 10.

[0037] The unloading assembly 5, located at the end of the conveying path, includes an adjustable gripper mechanism.

[0038] And a negative pressure adsorption fixing mechanism located at the bottom of the workbench 1.

[0039] The closed-loop conveyor assembly in this embodiment achieves continuous cyclic testing of electronic components through the closed-loop structure of synchronous belt and synchronous roller, improving testing efficiency and making it particularly suitable for mass production scenarios.

[0040] Detachable snap-fit ​​structure: Allows for quick replacement of component fixing molds of different specifications, adapts to various electronic component testing needs, and improves equipment versatility;

[0041] The test component integrates an electric actuator: the electric actuator precisely controls the downward stroke of the test probe, ensuring test contact stability and avoiding damage to the component due to excessive pressure from the probe;

[0042] Negative pressure adsorption fixing mechanism: Combining the adsorption force at the bottom of the workbench with mechanical fixing, it reduces the impact of equipment vibration on probe contact accuracy during testing.

[0043] In a specific example, the unloading assembly 5 includes an unloading frame 51 disposed on the upper end of the workbench 1, an unloading rod 52 extending vertically on the unloading frame 51, an adjustment groove 53 with a telescopic cylinder 54 inside the unloading rod 52, and an electric gripper 55 with force feedback function connected to the end of the telescopic cylinder 54.

[0044] The force feedback electric gripper in this embodiment: adjusts the gripping force in real time through the force feedback function to avoid deformation or damage to electronic components due to excessive clamping, and is especially suitable for non-destructive cutting of precision components;

[0045] Adjustable telescopic cylinder: The horizontal position of the gripper can be flexibly adjusted through the adjustment groove to adapt to the positioning requirements of fixed molds of different sizes.

[0046] In a specific example, the mounting assembly 3 includes multiple snap-fit ​​frames 31 disposed on the surface of the timing belt 23. Each snap-fit ​​frame 31 has snap-fit ​​holes 32 on both sides. The lower end of the fixing mold 4 is fixedly connected to a snap-fit ​​block 33. Each snap-fit ​​block 33 has a circular groove 34 on both sides. A snap-fit ​​spring 35 is fixedly connected inside the circular groove 34. The other end of the snap-fit ​​spring 35 is fixedly connected to a snap-fit ​​connector 36. The snap-fit ​​connector 36 snaps into the snap-fit ​​hole 32.

[0047] The spring snap-fit ​​structure of this embodiment: the snap-fit ​​spring provides elastic preload to ensure stable locking between the snap-fit ​​connector and the snap-fit ​​hole, while allowing for quick disassembly and assembly with one hand, thus improving mold change efficiency;

[0048] Modular design: The separate structure of the snap-fit ​​frame and the fixed mold simplifies the maintenance process and reduces equipment downtime.

[0049] In a specific example, the fixed mold 4 includes a mold base 41, the upper end of the mold base 41 is provided with a component groove 42, both sides of the component groove 42 are provided with lead wire grooves 43, the upper end of the mold base 41 is provided with a test groove 44 inside the lead wire groove 43, both sides of the upper end of the mold base 41 are provided with clamping grooves 45, and magnet blocks are provided inside the component groove 42 and the lead wire groove 43.

[0050] The magnetic block fixing element in this embodiment uses magnetic attraction to fix electronic component leads in a non-contact manner, avoiding the bending or scratching of leads caused by traditional mechanical clamping, and is especially suitable for surface mount components (such as SMD devices).

[0051] Test slot and lead slot co-design: The test probe directly contacts the component pin through the lead slot, reducing probe positioning error and improving the reliability of test signal transmission.

[0052] In a specific example, the negative pressure adsorption fixing mechanism includes a housing 15 fixedly connected to the lower end of the workbench 1, an electric push rod 16 fixedly connected inside the housing 15, and a rubber pad suction cup 17 fixedly connected to the other end of the electric push rod 16.

[0053] The rubber pad suction cup in this embodiment: the rubber pad suction cup is driven to contact the ground by an electric push rod, providing dual fixation (mechanical support + negative pressure adsorption), enhancing the vibration resistance of the equipment, and is suitable for high-precision testing environments.

[0054] Adjustable height: The electric push rod enables adaptive adjustment of the suction cup height, making it compatible with different ground flatness conditions.

[0055] In a specific example, the conveying assembly 2 further includes a guide support system disposed inside the synchronous belt 23. The guide support system includes a support plate 13 fixedly connected to one side of the conveying assembly 2. Support plates 14 are fixedly connected to the inner side of each support plate 13. There are two support plates 14, and each support plate 14 is slidably connected to the inner side of the synchronous belt 23.

[0056] In this embodiment, the support plate is slidably connected to the timing belt: the double support plate provides multi-point support to the inner side of the timing belt, preventing the timing belt from deforming or slipping due to uneven load, and extending the service life of the timing belt.

[0057] Integrated support plate design: simplifies the structural complexity of the conveyor components and reduces assembly and maintenance costs.

[0058] In a specific example, the upper end of the bracket 7 is slidably inserted into the upper end of the test plate 9, and the upper ends of the test plate 9 are fixedly connected to both sides of the upper end with limit rods 12. The upper end of the bracket 7 is provided with limit holes 11, and the limit rods 12 and limit holes 11 are inserted into each other.

[0059] In this embodiment, the insertion rod and the insertion hole are matched: physical limiting ensures the vertical downward trajectory of the test board, avoiding short circuits or poor connections caused by probe misalignment.

[0060] Sliding plug-in structure: Allows the test board to move freely up and down in the vertical direction while restricting horizontal displacement, balancing flexibility and accuracy.

[0061] The working principle and advantages of this utility model are as follows: First, by moving the device to a suitable position, the electric push rod is controlled to move the rubber pad towards the inside of the outer shell. During the movement of the rubber pad suction cup, the air pressure at the bottom of the suction cup decreases, generating suction force, thus firmly fixing the device. Then, the snap-fit ​​block is inserted into the snap-fit ​​frame. During insertion, the snap-fit ​​connector is squeezed into the circular groove. After the snap-fit ​​block is fully inserted into the snap-fit ​​frame, the snap-fit ​​hole aligns with the circular groove. At this point, the snap-fit ​​connector will pop out of the circular groove under the action of the snap-fit ​​spring, allowing it to snap into the snap-fit ​​hole, thus achieving the snap-fit ​​effect. This allows for the installation of the matching fixing mold. Electronic components can then be placed inside the component slot, and the component leads can enter the lead wire slot. Both the component slot and the lead wire slot are equipped with magnets, allowing for the placement of the electronic components. A magnetic attraction effect is achieved, and then the conveyor motor starts, driving the synchronous belt to move. Once the synchronous belt reaches the test position, it stops, and the test probe moves downwards to insert into the test slot, making contact with the component pins, thus achieving the test effect. Simultaneously, the conveyor assembly enables cyclic testing, increasing the testing efficiency of electronic components. During testing, the test probe can be used to test the component's condition. After the test, the signal is transmitted to the control equipment, and the synchronous motor records the drive steps. The control equipment controls the unloading assembly. Components that pass the test enter the good unloading station of the unloading assembly and are unloaded by an electric gripper. Components that fail the test enter the scrap unloading station of the unloading assembly and are also unloaded by an electric gripper. This facilitates the unloading of electronic components and, through automated design, reduces labor while increasing the testing efficiency of electronic components.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
