Description

Technical Field

[0001] This invention relates to the field of testing equipment, and more specifically to a product propulsion module. Background Technology

[0002] In the production testing of electronic devices, modules, or connectors, ensuring a stable and reliable electrical connection between the device under test (DUT) and the testing equipment is fundamental to guaranteeing the accuracy and efficiency of test results. In existing technologies, a common and direct method of test connection relies on manual operation. The operator holds or initially places the DUT near the testing station, and through visual observation and tactile feedback, manually adjusts the position and angle of the DUT to align its connectors (such as plugs, contacts, or test points) with the corresponding interfaces (such as sockets, probes, or test fixtures) on the testing equipment, applying force to complete the physical connection. After the test is completed, the two are manually separated.

[0003] However, this manual operation mode, which relies heavily on human experience and feel, may cause physical damage to the device under test (DUT) in practical applications. Because the DUT is in a free state without effective guidance or posture constraints throughout the insertion and removal process, its position and angle are entirely controlled by the operator's hand movements. When the operator applies a pushing force to move the DUT towards the test device and attempt to connect, or applies a reverse force to pull it out, the direction, magnitude, and point of application of the force are difficult to maintain precisely. Even slight deviations in the force line can easily cause the DUT to tilt slightly, twist, or momentarily jump at the moment of contact. This unstable movement can cause misalignment and friction between the DUT's connector and the corresponding interface of the test device, scratching the contacts or the connector housing surface. Secondly, at the critical state of connection or disconnection, misalignment or improper force can easily lead to stress concentration, posing a risk of DUT housing deformation, internal solder joint cracking, or terminal damage. Summary of the Invention

[0004] The purpose of this invention is to propose a product propulsion module that aims to solve the problems of unstable device connection, scratches, and structural damage caused by manual insertion and removal.

[0005] This invention provides a product propulsion module, comprising: a workbench; a testing unit disposed on the workbench, the testing unit having a plug-in end for insertion with a test piece; a moving unit including a moving plate, a first stabilizer located above the moving plate, and a second stabilizer disposed on the moving plate, the first stabilizer and the second stabilizer enclosing to form a limiting space restricting the displacement of the test piece; and a sliding guide structure disposed between the moving plate and the workbench, wherein the moving plate moves along the surface of the workbench under the action of a driving force to allow the test piece to be inserted into or separated from the plug-in end of the testing unit.

[0006] Preferably, the first stabilizing component is a limiting roller, which limits the measured component in the vertical direction and moves relative to the moving plate under the drive of an external force.

[0007] Preferably, the moving unit further includes a driving component for providing driving force, the driving component being connected to the moving plate, two opposing slide rails being mounted on the moving plate, a slider being slidably mounted on each of the two slide rails, a mounting post being detachably mounted on each of the two sliders, a limiting roller being rotatably mounted on each of the two mounting posts, and two guide plates being fixedly mounted on the worktable, with the two mounting posts being slidably connected to the two guide plates respectively.

[0008] Preferably, each of the two guide plates has a slide rail on its surface. The slide rail includes a horizontal section and a bent section extending from the end of the horizontal section. The two slide rails are arranged in a mirror-symmetrical manner along the insertion direction of the test unit.

[0009] Preferably, in the height direction, there is a first gap between the bottom surface of the limiting roller and the upper surface of the test piece.

[0010] Preferably, the second stabilizing component is a limiting block, and there are several limiting blocks, which limit the test component in the horizontal direction.

[0011] Preferably, in the horizontal direction, a second gap exists between the side of the plurality of limiting blocks near the test piece and the test piece.

[0012] Preferably, a gasket made of Teflon material is attached to the surface of each of the limiting blocks.

[0013] Preferably, the sliding guide structure includes a guide rail disposed on the worktable and a guide block that slides with the guide rail, and the moving plate is fixedly installed on the guide block.

[0014] Preferably, the product propulsion module further includes an optical fiber plug assembly, which includes a drive handle disposed on the movable plate, an abutment block connected to the drive handle, a movable block abutting against the abutment block, and an optical fiber plug disposed on the movable block. The drive handle drives the abutment block to abut against the movable block, so that the movable block drives the optical fiber plug to move along the upper surface of the movable plate.

[0015] Compared with existing technologies, it has the following beneficial effects: The product propulsion module of this application uses a limiting space formed by the first and second stabilizing components to constrain the test piece, preventing tilting, twisting, or momentary jumping of the test piece due to the movement, acceleration, or stopping of the moving plate, or external forces generated when the test piece is inserted into the insertion end. Simultaneously, a sliding guide structure formed between the moving plate and the worktable restricts the movement direction of the sliding plate, preventing insertion deviation between the test piece and the insertion end due to unconstrained movement of the moving plate. Therefore, this product propulsion module, through the combined action of the limiting space and the sliding guide structure, avoids connection instability, scratches, and structural damage, ensuring insertion stability.

[0019] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: like Figure 1 and Figure 2As shown, the present invention provides a product propulsion module, including: a workbench 1, a test unit 2 disposed on the workbench 1, a moving unit 3, and a sliding guide structure 32, wherein the test unit 2 has a plug-in end for plugging into the test piece; the moving unit 3 includes a moving plate 31, a first stabilizer 33 located above the moving plate 31, and a second stabilizer 34 disposed on the moving plate 31, the first stabilizer 33 and the second stabilizer 34 enclosing to form a limiting space for restricting the displacement of the test piece; the sliding guide structure 32 is disposed between the moving plate 31 and the workbench 1, wherein the moving plate 31 moves along the surface of the workbench 1 under the action of a driving force, so that the test piece is plugged into or separated from the plug-in end of the test unit 2.

[0020] According to the solution of this embodiment, when performing the insertion and removal operation for product testing, the operator first places the test piece on the moving plate 31. At this time, the first stabilizing member 33 located above the moving plate 31 and the second stabilizing member 34 set on the moving plate 31 cooperate with each other to form a limiting space, which constrains the test piece from the vertical and horizontal directions, restricting its free displacement in the vertical and horizontal directions.

[0021] Subsequently, under the driving force, the moving plate 31, guided by the sliding guide structure 32 between itself and the worktable 1, moves smoothly along the surface of the worktable 1 towards the insertion end of the test unit 2. The sliding guide structure 32 ensures the accuracy of the moving trajectory of the moving plate 31. Throughout the propulsion process, the test piece is limited by the first stabilizer 33 and the second stabilizer 34, which restricts its position relative to the moving plate 31. At the same time, the sliding guide structure 32 restricts the direction of movement of the moving plate 31, preventing insertion deviation between the test piece and the insertion end caused by the unconstrained movement of the moving plate 31. Therefore, the product propulsion module, through the combined action of the limiting space and the sliding guide structure 32, avoids connection instability, scratches, and structural damage, ensuring the stability of the insertion.

[0022] The following detailed description uses specific examples: In some embodiments, the first stabilizing element 33 is a limiting roller, which limits the test piece in the vertical direction and moves relative to the moving plate 31 under the drive of an external force. When the moving plate 31 carrying the test piece moves towards the test unit 2, the limiting roller moves with the moving plate 31, continuously providing vertical limitation on the test piece. When the test is completed and the moving plate 31 retracts, the limiting roller moves away from the upper surface of the test piece, releasing the constraint on the test piece and facilitating its removal. The limiting roller achieves vertical displacement constraint on the test piece through rolling contact between its cylindrical wheel surface and the upper surface of the test piece, preventing the test piece from jumping up due to vibration or inertia during movement or insertion / removal.

[0023] In a specific embodiment, the limiting roller 33 can move relative to the moving plate 31 in at least one of the height direction and the horizontal direction under the drive of an external force. The horizontal direction can be the vertical insertion / removal direction, or the movement along the insertion / removal direction, or the oblique direction, or a combination of the above directions.

[0024] In some other embodiments, the first stabilizer 33 may also be an elastic element or a limiting element that flexibly contacts the upper surface of the test piece.

[0025] In some embodiments, such as Figure 3 and Figure 4 As shown, the moving unit 3 also includes a driving component 35 for providing driving force. The driving component 35 is connected to the moving plate 31. Two opposing slide rails 4 are mounted on the moving plate 31. Slider 5 is slidably mounted on each of the two slide rails 4. Mounting posts 6 are detachably mounted on each of the two sliders 5. Limiting rollers are rotatably mounted on the two mounting posts 6. Two guide plates 7 are fixedly mounted on the worktable 1. The two mounting posts 6 are slidably connected to the two guide plates 7. A slide rail 71 is formed on the surface of each of the two guide plates 7. The slide rail 71 includes a horizontal section 711 and a bent section 712 extending outward from the end of the horizontal section 711. The two slide rails 71 are arranged in a mirror-symmetrical manner along the insertion direction of the test unit 2.

[0026] In order to control the movement trajectory of the two limit rollers to move accurately according to the pre-set relative position between them and the workpiece during the movement of the moving plate 31, two guide plates 7 are fixedly installed on the worktable 1, and the lower ends of the two mounting columns 6 are slidably connected to the two guide plates 7 respectively (for example, sliding columns or other sliding parts are installed at the lower ends of the mounting columns 6). When the driving component 35 drives the moving plate 31 to move in a straight line along the worktable 1, the mounting column 6 can not only move with the moving plate 31, but its movement path is also forcibly constrained and guided by the slide rail 71 on the guide plate 7, so that the movement trajectory of the limit rollers strictly follows the pre-set route.

[0027] When the moving plate 31 carrying the test piece moves towards the test unit 2, the lower end of the mounting post 6 first moves along the bend 712 of the slide 71. At this stage, since the two bends 712 are symmetrically arranged and the bending paths of the two bends 712 gradually approach the center line between the two bends 712, it forces the two mounting posts 6 to drive the limiting rollers on them to produce a lateral convergent movement in opposite directions, so that the two limiting rollers can move from the outside to above the test piece and apply a vertical limit to the test piece. As the moving plate 31 continues to move, the lower end of the mounting post 6 enters the horizontal part 711 of the slide 71. At this time, the distance between the two limiting rollers remains unchanged. At this position, a stable vertical limit is applied to the test piece, restraining the horizontal rotation or jumping that may occur at the moment of insertion, and ensuring a smooth completion of the insertion action. Conversely, when the moving plate 31 retracts, the mounting column 6 moves in the opposite direction along the figure-eight path, and the bending part 712 guides the two limiting rollers to generate opposite lateral expansion movements, gradually loosening the constraint on the test piece and providing sufficient operating space for the test piece to be picked up and placed.

[0028] The figure-eight shaped slide 71 formed by the combination of two guide plates 7 creates a geometric constraint on the movement path of the mounting column 6 moving along the slide 71, transforming the linear motion of the moving plate 31 into the convergence and expansion motion of the two limiting rollers in the horizontal plane, thus achieving the effect that the two limiting rollers move synchronously while the driving component 35 drives the moving plate 31 to move.

[0029] In other embodiments, the drive member 35 can be a drive handle, which pushes the moving plate 31 to move along the set path of the sliding guide structure 32. Alternatively, the drive member 35 can be an electrically driven or pneumatically driven retraction drive member 35. Furthermore, by employing a detachable connection method (e.g., bolt connection or snap-fit) between the mounting post 6 and the slider 5, the height of the mounting post 6 can be easily adjusted, thereby adjusting the height of the limiting roller to accommodate different types of test pieces.

[0030] In some embodiments, a first gap exists between the bottom surface of the limiting roller and the upper surface of the test piece in the height direction. The second stabilizing member 34 is a limiting block, and there are several limiting blocks, which limit the test piece in the horizontal direction. In the horizontal direction, a second gap exists between the side of the several limiting blocks near the test piece and the test piece.

[0031] In the vertical direction, a first gap exists between the bottom surface of the limiting roller and the upper surface of the workpiece. This gap does not indicate a failure of the limiting roller's vertical limiting function, but rather serves to achieve a non-contact or near-contact flexible limiting of the workpiece. When the moving plate 31 is stationary or moving smoothly at low speed, this gap allows the workpiece a small amount of free space in the vertical direction, preventing scratches or unnecessary stress on the surface of the workpiece caused by rigid clamping. However, when the moving plate 31 is advancing, stopping, or experiencing external vibration, if the workpiece jumps upward due to inertia or disturbance, its displacement will reach the limit of the first gap and come into contact with the bottom surface of the upper limiting roller. At this point, the limiting roller, through its free rotation characteristic, converts the possible sliding friction into rolling friction, limiting further upward jumping of the workpiece while minimizing frictional damage to its surface. Therefore, the existence of the first gap actually sets a permissible small elastic range of movement, which ensures that the tested part is not damaged by pressure under normal conditions, and can provide flexible vertical limiting protection instantly in case of unexpected situations.

[0032] The second stabilizing element 34 is a limiting block arranged in the horizontal direction, which mainly serves to limit the displacement of the measured part in the horizontal plane (i.e., in the X and Y axis directions). Several limiting blocks surround the measured part from different sides (such as front, back, left, right or a combination thereof), and the inner side of the limiting block contacts the side of the measured part to form a horizontal constraint, preventing the measured part from sliding horizontally, rotating or shifting laterally during the movement of the moving plate 31.

[0033] In the horizontal direction, a second gap is left between the side of several limiting blocks closest to the test piece and the corresponding side of the test piece. Similar to the principle of the first gap, this second gap allows the test piece a small amount of movement in the horizontal plane, avoiding damage to the appearance of the test piece caused by direct contact between the limiting blocks and the test piece. When the test piece tends to move laterally beyond the range of this gap due to motion inertia or external force interference, the side of the test piece will immediately come into contact with the corresponding limiting block, and be blocked and corrected by the limiting block, so that its movement trajectory returns to the preset path.

[0034] In some embodiments, gaskets made of Teflon material are attached to the surfaces of several limiting blocks. Specifically, Teflon (polytetrafluoroethylene), as one of the solid materials with the lowest known coefficient of friction, has excellent self-lubricating and non-stick properties. When the test piece comes into contact with the limiting blocks due to inertia or vibration during advancement, the presence of the Teflon gaskets ensures an extremely low coefficient of sliding friction between the contact surfaces. This not only reduces heat and potential wear generated by friction but also eliminates the risk of scratches, wire drawing, or grinding damage that may occur on the surface of the test piece due to traditional metal or hard plastic limiting blocks.

[0035] In some embodiments, the sliding guide structure 32 includes a guide rail 321 disposed on the worktable 1 and a guide block 322 slidably engaged with the guide rail 321, and a moving plate 31 fixedly mounted on the guide block 322. Specifically, the guide rail 321 is fixedly mounted on the worktable 1, defining an accurate movement path for the moving plate 31. The guide block 322 is slidably connected to the guide rail 321, ensuring that the guide block 322 can only move along the length direction of the guide rail 321, avoiding deviation or torsion of the guide block 322 during movement. The moving plate 31 is fixed to the guide block 322 by bolts or other fastening methods, thereby transmitting the linear movement of the guide block 322 along the guide rail 321 to the moving plate 31, ensuring that the moving plate 31 can move stably in a straight line along the guide rail 321.

[0036] When the driving component 35 applies a driving force to the moving plate 31, the force is transmitted to the guide block 322 through the moving plate 31, causing the guide block 322 to slide smoothly along the guide rail 321. Since the sliding friction coefficient between the guide rail 321 and the guide block 322 is low and the movement is smooth, the moving plate 31 can move along the surface of the worktable 1 with minimal resistance, ensuring that the test piece can be accurately aligned with the insertion end on the test unit 2, eliminating problems such as alignment deviation or insertion / extraction stress concentration caused by bending, shaking or jamming of the movement trajectory.

[0037] In other embodiments, the sliding guide structure 32 may also be a sliding guide structure with a protrusion and a groove, or other guide structures that can achieve the smooth sliding.

[0038] In some embodiments, the product propulsion module further includes an optical fiber plug assembly 8, which includes a drive handle 81 disposed on a moving plate 31, an abutment block 82 connected to the drive handle 81, a moving block 83 abutting against the abutment block 82, and an optical fiber plug 84 disposed on the moving block 83. The drive handle 81 drives the abutment block 82 to abut against the moving block 83, so that the moving block 83 drives the optical fiber plug 84 to move along the upper surface of the moving plate 31.

[0039] Specifically, two mutually perpendicular tracks are fixedly installed on the surface of the movable plate 31. An abutment block 82 is slidably installed on one track, and a movable block 83 is slidably installed on the other track. Both the abutment block 82 and the movable block 83 have guide ramps on their bodies, and the two guide ramps abut against each other. When the drive handle 81 drives the abutment block 82 to move along one of the tracks, the abutment block 82 generates a thrust on the movable block 83, forcing the movable block 83 to move along the other track. During the movement of the movable block 83, the movable block 83 drives the optical fiber plug 84 installed on it to move synchronously.

[0040] The operator drives the abutment block 82 toward the moving block 83 by rotating or pushing the drive handle 81. Since the abutment block 82 and the moving block 83 abut against each other, the thrust of the abutment block 82 is directly transmitted to the moving block 83, forcing the moving block 83 to move linearly along the track preset on the upper surface of the moving plate 31. The fiber optic plug 84 fixed on the moving block 83 moves synchronously and moves toward the fiber optic interface on the test piece.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
