Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and more specifically, to a device for testing the PIN pin sockets of products. Background Technology

[0002] The original purpose of automotive products is to facilitate driver operation and enrich the passenger experience. Therefore, their functional requirements are increasing, and the number of required pin sockets is also increasing accordingly. In order to prevent phenomena such as misalignment, pin retraction, and damage that are difficult to distinguish with the naked eye from occurring during the production and testing of automotive products, it is necessary to test the pin sockets of the products.

[0003] Current testing equipment typically involves placing the product on a fixture fixed to a three-axis movable platform. The product is then moved below the testing device, which scans or captures images for comparison to determine the PIN pin socket's position. However, because the fixture can only move parallel to the X, Y, and Z axes, the testing device can only capture an image of the PIN pin socket from one angle, hindering accurate parameter measurement. Furthermore, for PIN pin sockets not on the same plane as the product, a single clamping operation is insufficient, requiring multiple clamping operations to change the product's orientation, and even changing fixtures capable of holding different orientations, thus reducing testing efficiency. Utility Model Content

[0004] To overcome the problem that the PIN pin socket detection of products can only collect data at a single angle in the prior art, this utility model provides a device for PIN pin socket detection of products. During the detection process, the angle of the PIN pin socket toward the detection device can be changed, thereby enabling the collection of data at different angles of the PIN pin socket.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for detecting PIN pin sockets of products, including a machine base, a detection device and a motion platform, both mounted on the machine base. The motion platform is located below the detection device. The motion platform includes a base, a first rotating platform mounted on the base and rotatably connected to the base, a first driving device mounted on the base and driving the first rotating platform to rotate, a second rotating platform rotatably connected to the first rotating platform, and a second driving device mounted on the first rotating platform and driving the second rotating platform to rotate; the rotation axis of the first rotating platform is perpendicular to the rotation axis of the second rotating platform.

[0006] In the above technical solution, the product is fixed on the second rotating platform. The first driving device can drive the first rotating platform to rotate, and the second driving device can drive the second rotating platform to rotate. The rotation axes of the first rotating platform and the second rotating platform are perpendicular to each other. Therefore, when the two rotate at different angles, the product placed on the second rotating platform will present different angles under the detection device. The detection device collects the PIN pin holes at different angles for use as detection data.

[0007] Furthermore, the base includes a mounting plate and support plates mounted on both sides of the mounting plate. The first rotating platform is mounted on the support plates and can rotate 360 ​​degrees under the drive of the first driving device. The support plates allow the first rotating platform to be mounted at a relatively high position, providing sufficient space for the first rotating platform to rotate 360 ​​degrees.

[0008] Furthermore, the second rotary table includes a connecting plate and a tooling plate. The connecting plate is rotatably connected to the second rotary table, and the tooling plate is mounted on the connecting plate for tooling fixation. The tooling plate is used to install tooling for clamping products. Different products correspond to different tooling. By pre-installing the tooling on the tooling plate, when inspecting different products, only the tooling plate needs to be replaced, making it more convenient to use.

[0009] Furthermore, handles are installed on both sides of the tooling plate. The handles facilitate the removal or installation of the tooling plate.

[0010] Furthermore, a clamping assembly and a connecting fixture are mounted on the tooling plate; the clamping assembly includes a clamping member and a driving member that drives the clamping member to move in the direction of the connecting fixture. The connecting fixture positions the product; after the product is positioned, the driving member drives the clamping member to press the product, thus fixing the product on the tooling plate.

[0011] Furthermore, the connecting fixture is provided with positioning holes; at least two sets of clamping components are provided, respectively located on both sides of the tooling plate. The positioning holes help the product to be positioned quickly, and the clamping components can provide clamping force in two directions, resulting in better product clamping performance.

[0012] Furthermore, both the first and second rotary tables are provided with multiple hollowed-out sections. These hollowed-out sections can reduce the weight of the first and second rotary tables, thereby reducing the load on the first and second drive devices.

[0013] Furthermore, it also includes a translation device mounted on the machine platform; the translation device includes a first slide module that is conveyed along a first direction, a fixed plate mounted on the output end of the first slide module, and a second slide module mounted on the fixed plate and conveyed along a second direction, wherein the first direction is perpendicular to the second direction; the motion platform is mounted on the output end of the second slide module. The cooperation of the first slide module and the second slide module allows the product on the motion platform to be positioned at different locations corresponding to the detection device, and also allows the motion platform to move away from the range of the detection device, facilitating product loading and unloading.

[0014] Furthermore, the detection device includes a mounting frame, an image acquisition device slidably connected to the mounting frame in a vertical direction, and a third driving device for moving the image acquisition device. The third driving device drives the image acquisition device to move in the vertical direction, allowing the image acquisition device to capture images of the PIN pin socket at different heights as needed.

[0015] Furthermore, the image acquisition device is a 3D camera.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Driven by the first and second driving devices respectively, the first and second rotating platforms allow the product mounted on the second rotating platform to rotate relative to the detection device at any angle. This enables the detection device to collect PIN pin holes at different angles for use as detection data, improving detection accuracy. Simultaneously, even if the PIN pin holes are located on different end faces, the rotation of the first and / or second rotating platforms allows the PIN pin holes at different positions to be aligned with the detection device without secondary clamping, improving detection efficiency.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0025] Example 1

[0026] like Figure 1 and 3The illustration shows an embodiment 1 of a device for PIN pin jack testing of a product, comprising a machine base 100, a testing device 200 mounted on the machine base 100, and a motion platform 300. The motion platform 300 is located below the testing device 200. The motion platform 300 includes a base 310, a first rotary table 320 mounted on and rotatably connected to the base 310, a first drive device 330 mounted on the base 310 and driving the first rotary table 320 to rotate, a second rotary table 340 rotatably connected to the first rotary table 320, and a second drive device 350 mounted on the first rotary table 320 and driving the second rotary table 340 to rotate. The rotation axis of the first rotary table 320 is perpendicular to the rotation axis of the second rotary table 340.

[0027] Specifically, the base 310 includes a mounting plate 311 and support plates 312 mounted on both sides of the mounting plate 311. The first rotating stage 320 is mounted on the support plate 312 and can rotate 360 ​​degrees under the drive of the first driving device 330. The support plate 312 makes the mounting position of the first rotating stage 320 relatively high, so that the first rotating stage 320 has enough space to rotate 360 ​​degrees.

[0028] Furthermore, the first rotary table 320 and the second rotary table 340 are provided with multiple hollowed-out portions. The hollowed-out portions can reduce the weight of the first rotary table 320 and the second rotary table 340, and reduce the load on the first drive device 330 and the second drive device 350.

[0029] In this embodiment, the detection device 200 includes a mounting bracket 210, an image acquisition device 220 slidably connected to the mounting bracket 210 in a vertical direction, and a third driving device 230 for moving the image acquisition device 220. The third driving device 230 drives the image acquisition device 220 to move in the vertical direction, allowing the image acquisition device 220 to capture images of the PIN pin socket at different heights as needed. The image acquisition device 220 is a 3D camera, which can be connected to the mounting bracket 210 via a bracket.

[0030] In this embodiment, both the first drive device 330 and the second drive device 350 are motors. In order for the first rotary table 320 and the second rotary table 340 to rotate 360 ​​degrees without wire tangling, the motors are connected to external devices through conductive slip rings.

[0031] The third drive device 230 is a slide module. The motor drives the lead screw to rotate, which in turn moves the slide along the lead screw. The slide is connected to the image acquisition device 220. The mounting bracket 210 is equipped with a slide rail. The image acquisition device 220 is slidably connected to the slide rail via a slider.

[0032] The working principle or workflow of this embodiment is as follows: The product is fixed on the second rotating platform 340. The first driving device 330 can drive the first rotating platform 320 to rotate, and the second driving device 350 can drive the second rotating platform 340 to rotate. The rotation axis of the first rotating platform 320 and the rotation axis of the second rotating platform 340 are perpendicular to each other. Therefore, when the two are rotated at different angles, the product placed on the second rotating platform 340 presents different angles under the detection device 200. The third driving device 330 drives the detection device 200 to move in the vertical direction to adjust the focal length of the image. Finally, the detection device 200 can collect PIN pin holes at different angles for use as detection data.

[0033] Furthermore, for products requiring detection of PIN pin sockets located on different surfaces, after fixing the product to the second rotating platform, the first drive device 330 and the second drive device 350 orient the PIN pin sockets toward the image acquisition device 220, and the third drive device 230 adjusts the height of the image detection device 200 to facilitate clear image acquisition for detection. When detecting PIN pin sockets in different positions, only the first drive device 330 and the second drive device 350 need to be adjusted to orient the PIN pin sockets in other positions toward the image detection device 200.

[0034] The beneficial effects of this embodiment are as follows: Driven by the first driving device 330 and the second driving device 350 respectively, the first rotating stage 320 and the second rotating stage 340 allow the product mounted on the second rotating stage 340 to rotate relative to the detection device 200 at any angle. This enables the detection device 200 to collect PIN pin holes at different angles for use as detection data, improving detection accuracy. Simultaneously, even if the PIN pin holes are located on different end faces, the rotation of the first rotating platform and / or the second rotating platform allows the PIN pin holes at different positions to be aligned with the detection device 200 without secondary clamping, improving detection efficiency.

[0035] Example 2

[0036] like Figure 2 The following is an embodiment 2 of a device for detecting PIN pin sockets of a product. The difference between this embodiment and the first embodiment is that the second rotating stage 340 is further defined.

[0037] The second rotary table 340 includes a connecting plate 341 and a tooling plate 342. The connecting plate 341 is rotatably connected to the second rotary table 340, and the tooling plate 342 is mounted on the connecting plate 341 and used for tooling fixation. In this embodiment, the tooling plate 342 is mounted on the connecting plate 341 by fasteners.

[0038] Furthermore, handles 343 are installed on both sides of the tooling plate 342. The handles 343 facilitate the removal or installation of the tooling plate 342.

[0039] Furthermore, a clamping assembly 344, a connecting fixture 345, and a handle 343 are mounted on the tooling plate 342.

[0040] Handles 343 are located on both sides of the tooling plate 342 to facilitate the removal or installation of the tooling plate 342.

[0041] The clamping assembly 344 includes a clamping member 3441 and a driving member 3442 that drives the clamping member 3441 to move in the direction of the connecting fixture 345. The connecting fixture 345 positions the product. After the product is positioned, the driving member 3442 drives the clamping member 3441 to press the product, thus fixing the product onto the tooling plate 342. The driving member 3442 is a linear driving member; in this embodiment, it is a cylinder.

[0042] The connecting fixture 345 is provided with positioning holes 3451; at least two sets of clamping components 344 are provided and are respectively provided on both sides of the tooling plate 342. The positioning holes 3451 can help the product to be positioned quickly, and the clamping components 344 can provide clamping force in two directions, resulting in better clamping effect on the product.

[0043] The working principle of this embodiment is as follows: The product is placed on the connecting fixture 345, and the product is positioned through the positioning hole 3451 of the connecting fixture 345. After the product is positioned, the driving component is activated. The driving component is a cylinder, which is essentially opening the air supply device or valve, allowing compressed air to drive the driving component 3442 to operate, causing the clamping component 3441 to press the product firmly onto the connecting fixture. The tooling plate 342 is used to install the tooling for clamping the product. Different products correspond to different tooling. The tooling is pre-installed on the tooling plate 342. When inspecting different products, only the tooling plate 342 needs to be replaced, making it more convenient to use.

[0044] The remaining features and working principles of this embodiment are the same as those of Embodiment 1.

[0045] Example 3

[0046] Embodiment 3 of a device for detecting PIN pin sockets in a product differs from Embodiment 1 or Embodiment 2 in that, as shown in Embodiment 1, Embodiment 2, Embodiment 3 is based on Embodiment 1 or Embodiment 2. Figure 1As shown, it also includes a translation device mounted on the machine base 100; the translation device includes a first slide module 110 that is conveyed along a first direction, a fixed plate 120 mounted on the output end of the first slide module 110, and a second slide module 130 mounted on the fixed plate 120 and conveyed along a second direction, the first direction being perpendicular to the second direction; a motion platform 300 is mounted on the output end of the second slide module 130. The cooperation of the first slide module 110 and the second slide module 130 allows the product on the motion platform 300 to correspond to the detection device 200 at different positions, and also allows the motion platform 300 to move away from the range of the detection device 200, facilitating product loading and unloading.

[0047] In this embodiment, both the first slide module 110 and the second slide module 130 include a lead screw, a motor for driving the lead screw to rotate, and a slide connected to the lead screw by a thread, wherein the slide serves as the output end. A slide rail is provided on the machine base 100, and the fixed plate 120 slides on the slide rail via a slider. A slide rail is also provided on the fixed plate 120, and the base 310 of the motion platform 300 slides on the slide rail via a slider.

[0048] The remaining features and working principles of this embodiment are the same as those of Embodiment 1 or 2.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
