[0062] With the development of society, various products emerge in an endless stream. The update and iteration of the same product or the alternating iteration of different products all have a trend towards highly refined development, which makes product quality control more stringent and makes product testing more difficult. Traditional manual testing or semi-automatic testing for sample trial production cannot guarantee product quality and test performance. In order to ensure the stability of product testing, an automated testing system is urgently needed.
[0063] The present invention proposes a test system, see Figures 1 to 10 , is an embodiment of the test system proposed in this application, and the test system will be described in detail below in conjunction with specific drawings.
[0064] See also Figures 1 to 10The test system 1000 is provided with a loading station, at least one testing station and an unloading station. The test system 1000 includes a conveying device 100, a loading device 200, a testing device 300 and an unloading device 400. The conveying route of the conveying device 100 is arranged to the loading station, the testing station and the unloading station for conveying products; the loading device 200 is arranged at the loading station, and the loading device 200 includes a preparation device 201 and a first transfer device 202. The preparation device 201 is used to carry the product to be tested, and the first transfer device 202 is used to transfer the product to be tested at the preparation device 201 to the delivery station. The testing device 300 is arranged at the testing station, the testing device 300 comprises a testing unit 301 and a second transfer device 302, the testing unit 301 is detachably arranged at the testing station, the second transfer device 302 is used to transfer products between the testing unit 301 and the conveying device 100; the unloading device 400 is arranged at the unloading station, the unloading device 400 comprises a storage device 401 and a third transfer device 402, the storage device 401 is used to carry the completed tested products, the third transfer device 402 is used to transfer the completed tested products on the conveying device 100 to the storage device 401.
[0065] In the technical solution of the present invention, the test system 1000 is provided with the loading device 200, the unloading device 400, the test device 300 and the conveying device 100. The product at the loading device 200 is sequentially conveyed to the test device 300 for testing by the conveying device 100, and then conveyed to the unloading device 400 for unloading, so as to meet the demand of automated testing. On the one hand, the automatic process is highly efficient, and on the other hand, the mechanical action is stable and the test accuracy is high, so as to meet the increasingly difficult automated testing demand of the product. On this basis, the number of the test devices 300 may not be limited, that is, a plurality of the test devices 300 may be provided between the loading device 200 and the unloading device 400, so as to test the different test items of the product in sequence, which is more automated. It should be noted that if a plurality of the test devices 300 are provided here, the test content shall be based on the actual test requirements of the product, especially the case where there is a sequence between the test items. No specific limitation is made here, and the test requirements can be met. In addition, the present application proposes that the test unit 301 in the test device 300 is detachably arranged to achieve modularity of the test system 1000, which is more applicable and can meet different testing requirements of the same product or even different products in the same test system 1000, which is more practical.
[0066] Specifically, the test unit 301 includes a test platform 1, a test fixture 2 and a test center 3. The test platform 1 can be detachably arranged at the test station, and a test area 1a is arranged thereon; the test fixture 2 includes a base 21 and a fixed structure 22, the base 21 is installed in the test area 1a, and a receiving area 21a is arranged on the base 21, and the fixed structure 22 is used to position and fix the product located in the receiving area 21a; the test center 3 is arranged below the test area 1a, and includes an excitation part for providing a test environment and a collection part for collecting product test information. The test unit 301 can be detachably arranged at the test station as described above, that is, the test unit 301 needs to form a complete test process by itself, so the test unit 301 is provided with the test hub 3, and the product test environment is provided by the excitation part on the test hub 3, and the product test information is collected by the collection part. The processing of the product test information can be completed in the test hub 3, or it can be completed by electrically connecting to an external processor, which is not limited here, and this item does not affect the detachable and replaceable feature of the test unit 301. Therefore, in order to meet the independent replaceable characteristics of the test unit 301 and to meet the modular structure of the test system 1000, in some embodiments of the test unit 301, the test unit 301 needs to be composed of the test platform 1 for carrying, the test fixture 2 for fixing the product and the test hub 3 for testing.
[0067] Specifically, the test fixture 2 also includes a communication device 24, which includes a communication part 241 placed on one side of the seat 21, and the communication part 241 can be movably arranged to have an electrical connection position close to the product and an avoidance position away from the accommodating area 21a. A connector 242 is provided at one end of the communication part 241, and the connector 242 is used to contact and electrically connect with the product in the accommodating area 21a at the electrical connection position; the conductive device 4 is correspondingly arranged on the test platform 1, and the conductive device 4 is used to drive the communication part 241 to move between the electrical connection position and the avoidance position, and the test hub 3 also includes a collection part electrically connected to the communication part 241. On the basis of the above-mentioned test unit 301, in the test unit 301 proposed in this embodiment, the communication device 24 is further provided on the test fixture 2, and the conductive device 4 is correspondingly provided on the test platform 1, and the communication device 24 is used to connect the test hub 3 in the test unit 301 with the product. Specifically, in order to facilitate the placement and removal of the product, the communication part 241 is movably provided in the communication device 24, and the communication part 241 moves close to or away from the accommodating area 21a, so that the communication part 241 can avoid the product when it is placed, and can be electrically connected to the product through the connector 242 when close to the product, thereby meeting the structural requirements of automatic electrical connection, and cooperating with the conductive device 4 in the test unit 301 to realize automatic electrical connection of the product. It should be noted here that whether the excitation unit and the collection unit need to be electrically connected to the product depends on the actual test requirements of the product and is not specifically limited here. For example, when the test requirement of the product is to test whether the running posture of the product is stable during operation, the corresponding collection unit does not need to be electrically connected to the product, and can be set as a visual inspection device 11 for remote detection. It is only necessary for the excitation unit to be electrically connected to the product to provide an operating environment such as operating power. Correspondingly, if the test is to determine the stability of the operating parameters of the product during operation, the excitation unit and the collection unit of the test center 3 need to be electrically connected to the product. In this embodiment, the detection is mainly for commonly used electronic components, electronic modules and other modules. It only requires the excitation unit to provide directional vibration, and the excitation unit does not need to be electrically connected to the product. The collection unit is electrically connected to the product to collect product test data. Therefore, in this embodiment, the excitation unit is arranged below the test area 1a to provide the vibration required for the up and down direction test, and the collection unit is electrically connected to the communication unit 241 to be electrically connected to the product through the communication unit 241 to meet the construction of the test environment.
[0068] In addition, the fixing structure 22 includes a cover 221 rotatably mounted on the base 21, and a locking device 23 is provided between the cover 221 and the base 21, the locking device 23 is used to fix the cover 221 to cover the base 21, and the cover 221 and the base 21 are used to clamp and fix the product. The specific setting of the fixed structure 22 is mainly based on the actual product structure and test requirements, and can perform the required fixation on the product to ensure its stability during the test process. In the first embodiment of the fixed structure 22 proposed in the present application, the fixed structure 22 includes the cover body 221 rotatably mounted on the base body 21, and the cover body 221 is used to cover the base body 21 when the product is placed on the base body 21, so as to position and fix the product in the accommodating area 21a. Correspondingly, the locking device 23 is provided between the cover body 221 and the base body 21, so as to automatically lock the cover body 221 and the opening and closing device adapted to the test system 1000 to automatically open and close the cover body 221, thereby meeting the automation requirements.
[0069] Specifically, the locking device 23 includes a fastener 231 rotatably mounted on the cover 221 and a fastener 232 disposed on the base 21, the fastener 231 includes a fastening portion 2311 and an unlocking portion 2312 located at both sides of its rotation axis, and when the cover 221 is in the covered state, the fastening portion 2311 is fastened to the fastening portion 232 to lock the cover 221. The specific structural arrangement of the locking device 23 can also be various, including but not limited to a fastening structure, a pin connection structure, a clamping structure, etc. In this embodiment, the locking device 23 is set as a fastening structure, specifically, the fastener 231 is rotatably mounted on the cover 221, and the fastener 231 includes the fastening portion 2311 and the unlocking portion 2312 located at both ends thereof, and the fastening portion 2311 can be fastened to the fastening portion 232 on the base 21 to lock the cover 221 and the base 21, and the structure is simple and the effect is good.
[0070] Specifically, an unlocking device 5 is also provided on the test platform 1, and the unlocking device 5 includes a movably arranged unlocking member 5a, and the unlocking member 5a has a movable stroke approaching or moving away from the base body 21. When it approaches the base body 21, the unlocking member 5a pushes the unlocking portion 2312 to drive the fastener 231 to rotate, so that the holding portion 2311 disengages from the fastening portion 232 to unlock the locking device 23. The locking device 23 is configured as a snap-fit structure as described above. The unlocking portion 2312 is provided on the fastener 231 for unlocking the product. The specific operation method is not limited. For example, it can be manually operated, but it is obviously a non-automatic operation, which affects the efficiency. It can also be operated by the structure described above, for example, the second transfer device 302 provided on the test device 300 performs the unlocking operation instead, but it is obviously unstable. Therefore, in this embodiment, the unlocking device 5 is also provided on the test platform 1. The unlocking device 5 can be provided with a movable unlocking member 5a, so that the unlocking member 5a can be abutted against the unlocking portion 2312 when it is close to the seat body 21, thereby driving the fastener 231 to rotate, and then the buckling portion 2311 on the fastener 231 is disengaged from the buckling portion 232 on the seat body 21, thereby realizing the unlocking of the cover body 221. The structure is simple and the effect is good.
[0071] In addition, a torsion spring is provided at the rotational connection between the cover body 221 and the base body 21, and a covering device 6 is also provided on the test platform 1. The covering device 6 includes a movably arranged push portion 6a. During the movable stroke of the push portion 6a, the push portion 6a pushes the cover body 221 to cover the base body 21. In order to meet the automatic opening and closing of the cover body 221, a structure such as a manipulator that can realize the two-step operation of opening and closing the cover body 221 can be set on the test platform 1. However, such a setting is obviously cumbersome and costly. In this embodiment, the torsion spring is set at the rotational connection between the cover body 221 and the base body 21, so that after the locking device 23 releases the lock on the cover body 221, the elastic force of the torsion spring can drive the cover body 221 to open, that is, after the unlocking device 5 unlocks the cover body 221, the elastic force of the torsion spring is cooperated to realize the automatic opening of the cover body 221, and then the push portion 6a on the closing device 6 pushes the cover body 221 to resist the elastic force of the torsion spring and drive the cover body 221 to close on the base body 21 until the locking device 23 locks the cover body 221 on the base body 21, completing the steps of opening the cover body 221 to take out and place products and closing for testing. The structure is simple and the cost is low, which meets the use requirements. It should be noted here that, in addition to being used to cover the cover body 221, the covering device 6 can also be used to slow down the opening of the cover body 221, reduce the impact of the opening of the cover body 221, and play a protective role. That is, when the cover body 221 is driven by the torsion spring, the pushing portion 6a in the covering device 6 always presses against the cover body 221 and gradually moves along the opening direction of the cover body 221 to control the opening speed of the cover body 221 and meet the above-mentioned protective requirements.
[0072] In addition, in the second embodiment of the fixing structure 22 proposed in the present application, the fixing structure 22 includes a positioning hole 222 opened in the base body 21, a locking rod 223 detachably arranged in the positioning hole 222, and a locking structure arranged between the positioning hole 222 and the locking rod 223, the locking rod 223 has a locking position extending into the positioning hole 222 and an avoidance position away from the positioning hole 222, the upper end of the locking rod 223 exceeds the position of the positioning hole 222 and is laterally protruded with a locking portion 2231, the position where the lower end of the locking rod 223 extends into the positioning hole 222 is locked by the locking structure, so that the locking portion 2231 presses the product. The seat body 21 is provided with the positioning hole 222, and the positioning hole 222 is used to adapt to the locking rod 223, so that the product transferred by the second transfer device 302 to the top of the seat body 21 can be accurately positioned by the locking rod 223 inserted into the positioning hole 222 after being automatically placed on the seat body 21, thereby ensuring the accuracy of the product placed on the seat body 21. The locking rod 223 is locked in the positioning hole 222 by the locking structure, so that the locking part 2231 on the locking rod 223 is pressed against the surface of the product, thereby positioning and fixing the product in the accommodating area 21a.

With such a configuration, the locking groove is arranged around the locking rod 223, so that there is no need to limit the angle of the locking rod 223. The locking rod 223 only needs to be placed in the positioning hole 222, and the locking piece can cooperate with the locking groove to achieve locking, which is easy to operate. In addition, the end of the locking piece can be chamfered or rounded, so that when the locking piece extends into the locking groove, it can abut against the groove wall of the locking groove and push the locking rod 223 to continue to extend into the positioning hole 222, so that the locking part 2231 presses the product to ensure the stability of product fixation. Specifically, in one embodiment, the end of the locking member can be set as a spherical structure, and an elastic member is set between the spherical structure and the seat body 21, and the elastic member can keep the spherical structure partially extending into the positioning hole 222, and when the locking rod 223 extends into the positioning hole 222, the side wall of the locking rod 223 can push the spherical structure, so that the elastic member is compressed, and the spherical structure shrinks to the hole wall of the positioning hole 222, avoiding the locking rod 223, until the locking groove on the locking rod 223 is aligned with the spherical structure, and the elastic member is released, pushing the spherical structure into the locking groove, thereby completing the locking of the locking rod 223 and meeting the structural requirements. In this embodiment, the locking member is set to be driven by a driving member, so as to facilitate electric control drive, meet the requirements of automatic control, and the driving member is more stable.
[0074] In addition, a gripping structure 7 is provided on the test platform 1, and the gripping structure 7 is used to grip the locking rod 223 and drive the locking rod 223 to move between the locking position and the avoidance position. The gripping structure 7 is mainly used to grip and move the locking rod 223, that is, when the product is placed on the seat 21, the gripping structure 7 is controlled to place the gripped locking rod 223 into the positioning hole 222, which completes the positioning of the product on the one hand, and facilitates the subsequent locking of the locking rod 223 on the other hand, so as to position and fix the product. When the product needs to be removed, the gripping structure 7 is controlled to grip the locking rod 223 and move the locking rod 223 out of the positioning hole 222 to complete the unlocking of the product, so as to facilitate the subsequent removal of the product.
[0075] In addition, a positioning structure 8 is provided in the accommodating area 21a, and the positioning structure 8 includes a positioning groove opened in the seat body 21 and / or a positioning column provided in the seat body 21; and / or, the test unit 301 also includes a positioning device 9, and the positioning device 9 includes a positioning stopper 9a movably provided on the side of the test fixture 2, and the positioning stopper 9a has a positioning position close to the test fixture 2 and an avoidance position away from the test fixture 2.

In order to meet the automated testing process and ensure the stability of the product during testing, the present application needs to position the product in the accommodating area 21a to ensure the consistency of the product placement, and then ensure the consistency of the product placement during testing, so as to ensure the accuracy of the test. Specifically, there are many ways to position the product, and there is no need to make specific restrictions. It is mainly based on the actual structural requirements of the product, and it is sufficient to ensure that the product is accurately positioned. The present application provides two positioning methods. In one positioning method, the positioning structure 8 is provided in the accommodation area 21a. The positioning structure 8 is configured as the positioning groove and the positioning column. When the product is placed in the accommodation area 21a, the groove or through hole on the product is preferentially matched with the positioning column to achieve the first level positioning of the product. Then the product is matched with the positioning groove to achieve the second level positioning of the product. Finally, the positioning accuracy of the product is guaranteed. The structure is simple and practical. In another positioning method, the positioning device 9 provided on the test unit 301 is used for positioning. The positioning device 9 includes the positioning stopper 9a provided on the side of the test fixture 2. When the product is placed on the seat 21, the positioning stopper 9a moves toward the set positioning position, so that the product can be limited to the desired preset position. The number of the positioning stopper 9a is not limited, and is mainly based on actual needs. In this way, the product can be pre-positioned when it is placed on the seat 21, so as to ensure the positioning accuracy of the product and meet the requirements of the automation process.

In order to ensure the automation process of the test system 1000, the loading device 200 is also provided with the first positioning adjustment structure 203, so that after the first transfer device 202 picks up the product from the material preparation device 201, the product can be moved to the first positioning adjustment structure 203 for precise positioning of the product, so as to adjust the posture of product loading, so as to ensure the accuracy of product loading, and then ensure the stability of subsequent processes. Specifically, the first positioning adjustment structure 203 can be a positioning fixture. The first transfer device 202 places the product on the above-mentioned positioning fixture to complete the precise positioning and then takes it out and flows into the production line. The first positioning adjustment structure 203 can also be a visual inspection device 11, which is matched with the movable setting of the picking part on the first transfer device 202. After the visual inspection device 11 completes the detection of the product posture, the picking part on the first transfer device 202 is controlled to adjust the posture of the product to complete the precise positioning of the product. In addition, in order to meet the testing requirements of some products, such as the structural requirements in this application, the first flipping structure 204 is also provided at the feeding device 200 to flip the product from a state that is convenient for placement in the fixture to a state that is convenient for testing. In addition, in order to ensure the positioning follow-up of the product in the test process of the test system 1000, the present application also provides the barcode recognition structure 205 at the feeding device 200, so as to input the product information entering the production line through the barcode recognition structure 205, and even bind the product information with the conveying fixture 101 to meet the product traceability requirements.
[0081] In addition, the unloading device 400 also includes a detection structure 403, a second positioning adjustment structure 404, a second flipping structure 405 and a waste collection structure 406.

After completing the overall test process of the test system 1000, the product flows to the unloading device 400. At this time, it is necessary to judge whether the product is qualified. On the one hand, it is judged by the test results of the test system 1000, and on the other hand, it is also necessary to judge the appearance of the product. Therefore, the unloading device 400 is also provided with the detection structure 403. The detection structure 403 is used to detect the appearance of the product to ensure the appearance of the product leaving the factory. When the product appearance inspection fails, or the product is determined to be unqualified in the test results of the test system 1000, the third transfer device 402 transfers the product to the waste collection structure 406 for later repair or scrapping, so as to avoid the outflow of unqualified or abnormal products and ensure the quality of the products leaving the factory. In addition, corresponding to the first flipping structure 204 at the loading device 200, on the basis of the first flipping structure 204 being provided to flip the product from a state convenient for placement in the tooling to a state convenient for testing, the product that has completed the test needs to be transferred to the tooling at the storage device 401, so it is necessary to provide the second flipping structure 405 to flip the product in the opposite direction and restore it to the posture of the product placed on the preparation device 201, so as to facilitate placement in the storage device 401. Such a configuration also allows the tooling at the preparation device 201 and the storage device 401 to be common, so that the production cost is low. In addition, contrary to the function of the first positioning and adjusting structure 203 provided at the loading device 200, in order to facilitate the product to be placed back in the storage device 401, the unloading device 400 is provided with the second positioning and adjusting structure 404, so as to adjust the posture of the product through the second positioning and adjusting structure 404, so as to facilitate placement in the storage device 401.
[0082] In addition, the conveying device 100 includes a conveying fixture 101 and a conveying line body 102, wherein the conveying fixture 101 is used to carry products; the conveying line body 102 is arranged in a ring shape, and the conveying line body 102 passes through the loading station, the testing station and the unloading station. The conveying device 100 can be only the conveying line body 102, that is, similar to a conveying belt line, the product is placed on the surface of the belt line and is moved by the belt line, but it is obvious that this setting method is difficult to position the product, which affects the accuracy of the product during transportation, and will increase the failure rate of the test system 1000 due to inaccurate product posture positioning. Therefore, the present application sets the conveying device 100 so that the conveying fixture 101 is transported by the conveying line body 102, and the product is carried by the conveying fixture 101, and the product can be positioned by the conveying fixture 101 to ensure the stability of the posture of the product during transportation, so as to ensure the positioning accuracy of the product.
