[0002] In automotive parts assembly plants, testing equipment needs to be compatible with different products. Therefore, multiple connectors capable of matching different signal interfaces are required on the testing equipment. Consequently, each time a test product is changed, fixture replacement is necessary. Currently, fixture replacement is mostly done manually, by plugging and unplugging different connectors to transmit electrical signals and complete the test. This method is not only inefficient and labor-intensive, but manual replacement is also prone to errors, affecting test accuracy and causing connector wear, reducing signal transmission stability and impacting test accuracy.

[0003] Therefore, there is an urgent need for a testing device that can automatically change models and is highly efficient and accurate. Utility Model Content

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0029] like Figures 1-6 As shown, a multi-station fixture automatic changeover testing device includes a horizontal fixture plate 1, a fixture changeover module slidably connected to the horizontal fixture plate 1 in the vertical direction, and a product platform 2 and a product testing connector 3 that can move horizontally toward the fixture changeover module. The fixture changeover module includes multiple sets of test boxes 4 arranged vertically, and test fixtures, plugs 5, and pins 6 disposed on the test boxes 4. The pins 6 are made entirely of a highly conductive metal and can mate horizontally with the product testing connector 3, with the end of the pin 6 that mates with the product testing connector 3 being tapered. Multiple test products can be placed on the product platform 2, and the plugs 5 can move vertically or horizontally to mate with the corresponding test products.

[0030] Specifically, each test fixture and plug 5 within each test box 4 corresponds to a specific test product. The fixture changing module can slide vertically, allowing for rapid switching between multiple test products on the product platform 2. In other words, during operation of the multi-station automatic fixture changing test device, workers or robots can place test products on the product platform 2. Different test products can be placed at different positions on the product platform 2. Subsequently, the fixture changing module adjusts its height according to different test products, enabling the plug 5 in the corresponding test box 4 to mate with the corresponding test product. After the fixture changing module is adjusted to the appropriate height, both the product platform 2 and the product test connector 3 can move horizontally toward the fixture changing module (test box 4). After moving a certain distance, the product test connector 3 can mate horizontally with the pin 6, while the plug 5 can mate horizontally or vertically with the plug 6, thereby transmitting electrical signals and testing the product. After completing the test on the current product, the product platform 2 can retract horizontally to facilitate the replacement of a new test product. When switching the type of test product, the fixture changeover module can be height-adjusted again according to the testing requirements of the corresponding test product, so that the plug 5 in another set of test boxes 4 can mate with the test product. In other words, the multi-station fixture automatic changeover testing device in this technical solution requires minimal manual operation when changing test products; simple control commands are all that's needed to complete the changeover action, greatly shortening changeover time and improving testing efficiency. Simultaneously, the mating and plugging between the plug 5 on the test box 4 and the test product, and between the pin 6 and the product test connector 3, are all completed using specific mechanical movements. This effectively avoids mating errors and reduces wear on the connectors caused by improper mating operations, ensuring the stability of signal transmission and improving testing accuracy.

[0031] Furthermore, in some specific embodiments of this example, the product platform 2 can hold multiple test products at once. After the first test product is tested according to the above steps, the product platform 2 can first move backward a certain distance in the horizontal direction (out of the movement range of the fixture changing module). Then, the fixture changing module can adjust its height according to the testing requirements of the next test product. After the fixture changing module has completed its height adjustment, the product platform 2 can move horizontally toward the fixture changing module to test the next test product. This process is repeated, and the multi-station automatic fixture changing test device in this technical solution can complete the testing of multiple test products with a single test product loading.

[0032] Furthermore, such as Figure 5As shown, to further improve the stability of the test, the test fixture includes a roller holder 7 that can press the test product onto the product platform 2. The roller holder 7 includes a mounting base 701 and a rubber roller 702 rotatably connected to the mounting base 701. The roller holder 7 can fix the position of the test product on the product platform 2 before the test product is connected to the plug 5, that is, the rubber roller 702 can press down on the corresponding test product.

[0033] However, because the insertion direction of plug 5 and the test product is different, the structure for the drive roller pressure seat 7 to press the test product onto the product platform 2 is also different. Therefore, when plug 5 is connected to the test product in a horizontal direction, as... Figure 4 As shown, the corresponding plug 5 is horizontally positioned on the test box 4, and the roller pressure seat 7 is located at the output end of the drive cylinder 8. The drive cylinder 8 can drive the roller pressure seat 7 to move horizontally. During this process, since the direction of the plug 5's connection with the test product is consistent with the direction of the product platform 2's movement, this structure can complete the connection (signal transmission) between the plug 5 and the test product through the movement of the product platform 2. In this technical solution, the drive cylinder 8 can first drive the roller pressure seat 7 to move towards the product platform 2, so that the rubber roller 702 on the roller pressure seat 7 can roll on the corresponding test product. At the same time, since the rubber roller 702 itself has a certain deformation capability, in this technical solution, the rubber roller 702 can be adjusted to a height that can apply a certain pressure to the test product. That is, when the rubber roller 702 contacts the test product, the rubber roller 702 itself will deform due to the compression of the test product, thereby ensuring that the test product is tightly attached to the product platform 2.

[0034] Furthermore, when plug 5 is vertically aligned with the test product, such as Figure 5 As shown; the corresponding plug 5 is vertically positioned on the upright plate 9, and the roller pressure seat 7 is vertically floating on the upright plate 9. The upright plate 9 is located at the output end of the lifting cylinder 10, which can drive the upright plate 9 to move up and down vertically. Specifically, before the plug 5 in the test box 4 is connected to the test product, the lifting cylinder 10 can drive the roller pressure seat 7 and the plug 5 to move vertically downward. Since the roller pressure seat 7 floats vertically, it contacts the test product before the plug 5, and provides stable pressure to the test product during the connection process, thus ensuring that the test product is tightly attached to the product platform 2.

[0035] The roller pressure seat 7 is floating vertically on the upright plate 9. Its specific structure is as follows: the roller pressure seat 7 is slidably connected to the upright plate 9 via a linear guide rail 11. The upright plate 9 is provided with an upper limit part 901 and a lower limit part 902 that can abut against the roller pressure seat 7. A support spring 12 is provided between the upper limit part 901 and the roller pressure seat 7 to drive the roller pressure seat 7 to move downwards. The linear guide rail 11 increases the linear motion accuracy of the roller pressure seat 7 in the vertical direction. The upper limit part 901 and the lower limit part 902 limit the maximum stroke of the roller pressure seat 7 relative to the upright plate 9 in the vertical direction. The support spring 12 is compressed when moving upwards relative to the upright plate 9, thereby providing pressure from the roller pressure seat 7 on the test product. Example 2

[0036] like Figures 1-6 As shown, based on Embodiment 1, the plug 5 includes a fixing base 501, a mounting base 502, and a probe holder 503 capable of docking with the test product. The probe holder 503 is disposed on the mounting base 502. The fixing base 501 is provided with multiple sets of nail-shaped guide shafts 504 that can movably pass through the mounting base 502, and the outer periphery of the nail-shaped guide shafts 504 is fitted with a pressure-relieving spring 505 that can elastically support the fixing base 501 and the mounting base 502. That is, the probe holder 503 has a certain degree of floating when docking with the test product, thereby reducing the impact force on the test product during docking.

[0037] Furthermore, in this embodiment, to ensure the accuracy of the linear motion of the fixture changing module, the product platform 2, and the product testing connector 3, such as... Figure 1 As shown, the fixture changing module also includes a lifting frame 13 for carrying the test box 4. The two ends of the lifting frame 13 are respectively set on the slides of two first servo slides 14, which are arranged vertically. The product platform 2 is set on the slide of a second servo slide 15, which is arranged horizontally. The product test connector 3 is set at the output end of the transfer cylinder 16, which can drive the product test connector 3 to move horizontally to the pin 6 for mating.

[0038] Meanwhile, to improve the stability of the test product on product stage 2, such as Figure 6As shown, the product stage 2 is equipped with several contour grooves 201 for placing test products. The test products can lie flat within the contour grooves 201. The contour grooves 201 are concave. When the test product is placed in the corresponding contour groove 201, the protrusions around the groove effectively restrict the test product's degree of freedom in the horizontal direction. Therefore, when the rubber roller 702 presses down on the test product, the position of the test product on the product stage 2 is relatively fixed and accurate, which helps to improve the consistency and repeatability of the test, ensuring that the position and state of the test product are the same in each test, thus making the test results more reliable and comparable.

[0039] In this embodiment, the horizontal tooling plate 1 can be equipped with sensors for detecting whether the product platform 2 has reached the detection position, whether the fixture changing module has reached the specified height, and whether the plug 5 matches the product, so as to ensure detection accuracy, improve production efficiency, realize automation and intelligence, and ensure the safety of personnel and equipment.

[0040] Working Principle: First, the test product can be placed on the product platform 2 by a worker or robot. Different test products can be placed in different positions on the product platform 2. Driven by the first servo slide 14, the fixture changing module can be height adjusted according to different test products. After the fixture changing module is adjusted to the appropriate height, the product platform 2 and the product test connector 3 can move horizontally toward the fixture changing module (test box 4) under the drive of the second servo slide 15 and the transfer cylinder 16, until the rubber roller 702 presses down on the test product. Then, the product test connector 3 mates with the pin 6 and the plug 5 mates with the plug 5, thereby realizing the transmission of electrical signals required for testing. However, since the insertion direction of the plug 5 and the test product is different, the structure of the drive roller pressure seat 7 pressing the test product onto the product platform 2 is also different.

[0041] In the first scenario, when the plug 5 aligns with the test product horizontally, the drive cylinder 8 moves the roller pressure seat 7 horizontally toward the product platform 2, allowing the rubber roller 702 on the roller pressure seat 7 to press down on the test product. In the second scenario, when the plug 5 aligns with the test product vertically, the lifting cylinder 10 drives the roller pressure seat 7 and the plug 5 to move vertically downwards until the rubber roller 702 on the roller pressure seat 7 presses down on the test product before the plug 5.

[0042] Subsequently, after completing the testing of the corresponding test product, the product platform 2 can be retracted horizontally to facilitate the replacement of a new test product. When switching the type of test product, the fixture changeover module can be height-adjusted again according to the testing requirements of the corresponding test product, so that the plug 5 in another set of test boxes 4 can be connected with the test product.

[0043] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
