Description

Technical Field

[0001] This invention relates to the field of electronic product manufacturing technology, and in particular to a transfer mechanism, testing equipment, and product testing method. Background Technology

[0002] During the manufacturing process of existing 3C products, their performance needs to be tested. During testing, the product must first be placed on the carrier of the testing equipment and fixed in place. Then, the carrier is moved so that the product's ports can contact the test head, and the test head can connect to the corresponding testing instruments so that the testing instruments can test the various performance characteristics of the product.

[0003] Existing product testing equipment requires moving clamping or pressing blocks to hold the product in place when it is secured. The carrier then needs to be moved so the product can contact the test head. To drive the clamping or pressing blocks and the carrier, the testing equipment needs at least two drive units. This results in high manufacturing costs, large space requirements, and, when the two drive units are electrically controlled, the coordinated sequential movement of the two units presents significant control challenges.

[0055] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0056] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0057] like Figure 1-7As shown, the present invention provides a testing device 1000. The testing device includes a transfer mechanism 100 and a testing mechanism 300. The transfer mechanism 100 is used to drive the product 200 to move, so that the product 200 can move to a position that docks with the testing mechanism 300, so that the testing mechanism 300 can test the product 200.

[0058] The transfer mechanism 100 includes a base 10, a carrier module 101, and a drive structure 50. The carrier module 101 includes a carrier 20 and a movable structure 102. The carrier 20 is used to carry the product 200, the product 200 can be placed on the carrier 20, and the carrier 20 is movably connected to the base 10 in a first direction and can move relative to the base 10 in the first direction.

[0059] The movable structure 102 is disposed on the carrier 20 and has a first state and a second state. When the movable structure 102 is in the first state, it can limit the position of the product 200 and keep the product 200 fixed on the carrier 20. When the movable structure 102 is in the second state, it can release the limitation on the position of the product 200, so that the product 200 can be removed from the carrier 20.

[0060] The drive structure 50 is movably connected to the base 10 in a second direction and is capable of moving relative to the base 10 in the second direction. The drive structure 50 includes a push block 51 and an operating lever 52. The push block 51 is used to push the carrier 20 to move relative to the base 10 in a first direction and is located on one side of the carrier 20 in the second direction. The operating lever 52 is capable of moving synchronously with the push block 51 in the second direction.

[0061] In this embodiment, the transfer mechanism 100 is configured such that when the push block 51 does not push the carrier 20 to move in the first direction, the operating lever 52 moves relative to the carrier 20 in the second direction, which enables the movable structure 102 to switch from the second state to the first state.

[0062] After the product 200 is placed on the carrier 20, the drive structure 50 is moved along the second direction, and the push block 51 and the operating lever 52 can move synchronously. When the push block 51 has not yet contacted the carrier 20 and has not yet pushed the carrier 20 to move along the first direction, the operating lever 52 can move relative to the carrier 20, enabling the movable structure 102 to switch from the second state to the first state, thereby limiting the position of the product 200 on the carrier 20. When the push block 51 contacts the carrier 20, the positions of the operating lever 52 and the carrier 20 remain fixed, and the push block 51 can push the carrier 20 to move along the first direction until the product 200 on the carrier 20 docks with the testing mechanism 300.

[0063] The transfer mechanism 100 provided in this embodiment, during the process of driving the drive structure 50 to move along the second direction, when the push block 51 does not contact the carrier 20, the operating rod 52 moves relative to the carrier 20 along the second direction, which can first switch the movable structure 102 from the second state to the first state to limit the position of the product 200. After that, when the push block 51 contacts the carrier 20, it can drive the carrier 20 to move along the first direction. Two operations are completed in one action, which simplifies the structure of the transfer mechanism 100, reduces the number of parts required by the transfer mechanism 100, and reduces the manufacturing cost and control difficulty of the transfer mechanism 100.

[0064] The carrier 20 is provided with a placement portion 21 for placing the product 200. The movable structure 102 includes a pressing block 40 and a first elastic member 30. The pressing block 40 is movably disposed on the carrier 20 in a second direction and is capable of moving relative to the carrier 20 in the second direction. The first elastic member 30 is disposed between the pressing block 40 and the carrier 20. The operating lever 52 is located between the pressing block 40 and the placement portion 21 in the second direction, and the operating lever 52 and the pressing block 40 can contact each other in the second direction.

[0065] When the movable structure 102 is in the first state, the pressing block 40 is close to the placement portion 21. When the movable structure 102 is in the second state, the pressing block 40 is away from the placement portion 21, and the first elastic member 30 elastically deforms. Under the action of the first elastic member 30, the pressing block 40 tends to be in the first state to press against the product 200. When no external force is applied to the pressing block 40, the pressing block 40 presses against the product 200 in the placement portion 21, thereby fixing the position of the product 200. When the movable structure 102 changes from the first state to the second state, the pressing block 40 moves away from the placement portion 21, and the first elastic member 30 elastically deforms.

[0066] In this embodiment, the transfer mechanism 100 is configured such that when the push block 51 and the carrier 20 are a predetermined distance d apart in the second direction, the operating lever 52 contacts the pressing block 40, thereby keeping the movable structure 102 in the second state. 。

[0067] It should be noted that, Figure 5 and Figure 6 In this text, the yy axis represents the first direction, the xx axis represents the second direction, and the zz axis represents the third direction. In this text, the placement part 21 is a groove formed on the carrier 20. The pressing block 40 is away from the placement part 21, which should be understood as the pressing block 40 being located outside the placement part 21. Conversely, the pressing block 40 is close to the placement part 21, which should be understood as at least a portion of the pressing block 40 extending into the placement part 21.

[0068] As explained above, when no external force is applied to the pressing block 40, the pressing block 40 will approach the placement portion 21 to press against the product 200 inside the placement portion 21. When the push block 51 and the carrier 20 are a predetermined distance d apart in the second direction, the operating lever 52 contacts the pressing block 40, applies a force to the pressing block 40, causes the first elastic member 30 to elastically deform, and locks the pressing block 40 in a position away from the placement portion 21, so that the movable structure 102 is held in the second state (e.g., Figure 1 (As shown). When the active structure 102 is in the second state, the product 200 can be placed in the placement section 21.

[0069] After the product 200 is placed in the placement section 21, the push block 51 moves towards the carrier 20 in the second direction. It must first pass through the predetermined distance d mentioned above before it can contact the carrier 20, thereby pushing the carrier 20 to move in the first direction. The push block 51 and the operating lever 52 belong to the drive structure 50. When the push block 51 moves, the operating lever 52 can move synchronously. Thus, when the push block 51 passes through the predetermined distance d mentioned above, the carrier 20 will not move, and the operating lever 52 will move relative to the carrier 20 in the second direction towards the placement section 21, so that the pressing block 40 can move towards the placement section 21 under the action of the first elastic member 30. When the push block 51 contacts the carrier 20 after passing through the predetermined distance d, the relative position of the operating lever 52 and the carrier 20 in the second direction can be kept fixed. At this time, the pressing block 40 also moves into place and can press against the product 200, thereby fixing the product 200 in the placement section 21. Then push block 51 continues to move along the second direction, which can push carrier 20 to move along the first direction to the predetermined position.

[0070] As can be seen, in the transfer mechanism 100 provided in this embodiment, the push block 51 needs to travel a predetermined distance d to contact the carrier 20 in order to push the carrier 20 to move. When the push block 51 has traveled the predetermined distance d, the carrier 20 remains stationary, and the operating lever 52 moves synchronously with the push block 51, moving relative to the carrier 20 towards the placement part 21, so that the pressing block 40 can move towards the placement part 21 under the action of the first elastic member 30. When the push block 51 contacts the carrier 20, the pressing block 40 has moved to a position close to the placement part 21 and presses against the product 200. Afterwards, the push block 51 continues to move along the second direction, which can drive the carrier 20 to move to the predetermined position. The transfer mechanism 100 provided in this embodiment only needs to drive the driving structure 50 to move along the second direction to first make the pressing block 40 press and fix the product 200, and then drive the carrier 20 to move along the first direction to the preset position.

[0071] To enable the carrier 20 to be movably connected to the base 10 along a first direction, the transfer mechanism 100 further includes a slide rail 23 connected to the carrier 20 and a slider (not shown) connected to the base 10. The slide rail 23 extends along the first direction, and the slider is slidably connected to the slide rail 23 along the first direction, thereby allowing the carrier 20 to move relative to the base 10 along the first direction via the slide rail 23 and the slider. The cooperation between the slide rail 23 and the slider ensures the movement accuracy of the carrier 20 relative to the base 10.

[0072] In this embodiment, when the push block 51 contacts the carrier 20, the operating lever 52 and the pressing block 40 disengage. Thus, the position of the pressing block 40 is no longer limited by the operating lever 52, and it can adhere tightly to the product 200 under the action of the first elastic member 30, thereby reliably fixing the product 200 within the placement portion 21.

[0073] In this embodiment, the first direction and the second direction are set at an angle, and the moving direction of the carrier 20 is inclined to the moving direction of the drive structure 50. Under the push of the push block 51, the carrier 20 moves along the second direction and can move to a predetermined position to meet the needs of product 200 testing.

[0074] For ease of explanation, let the direction perpendicular to the second direction be the third direction. When the pusher 51 pushes the carrier 20 to move along the first direction, it is equivalent to pushing the carrier 20 to move along both the second and third directions.

[0075] In this embodiment, the push block 51 includes a push block body 511 and a rolling element 512 rotatably connected to the side of the push block body 511 near the carrier 20. The rolling element 512 is used for rolling contact with the carrier 20. When the push block 51 pushes the carrier 20 to move in the second direction, the rolling element 512 rolls into contact with the carrier 20. The number of rolling elements 512 can be two, three, or even more. In this embodiment, two rolling elements 512 are spaced apart.

[0076] When the pusher 51 pushes the carrier 20 to move in the first direction, the rolling element 512 can roll on the carrier 20 in the third direction. The friction between the rolling element 512 and the carrier 20 is small, which makes it easier for the pusher 51 to push the carrier 20 to move. This prevents the pusher 51 from being unable to move in the third direction due to the large friction between the pusher 51 and the carrier 20, thus preventing the pusher 51 from pushing the carrier 20.

[0077] In this embodiment, a bearing is connected to the push block body 511, and the outer ring of the bearing can be regarded as the aforementioned rolling element 512. It is conceivable that in other embodiments of the present invention, the aforementioned rolling element 512 can also be other components that can roll and contact the carrier 20, such as rollers or cam rollers, and is not limited here.

[0078] In this embodiment, the driving structure 50 has a first position (e.g., Figure 5 As shown), the second position after moving from the first position along the second direction (as shown). Figure 6 (As shown). When the drive structure 50 is in the first position, the push block 51 and the carrier 20 are separated by a predetermined distance d in the second direction. During the process of the drive structure 50 moving from the first position to the second position, the push block 51 pushes the carrier 20 to move along the first direction so that the product 200 on the carrier 20 can dock with the testing mechanism 300.

[0079] The pressing block 40 includes a body portion 41 movably connected to the carrier 20 along a second direction, and a vertical portion 42 connected to the body portion 41. A first elastic member 30 is disposed between the body portion 41 and the carrier 20. The vertical portion 42 is used to contact the operating lever 52. When the drive structure 50 is in the first position and the second position, the vertical portion 42 and the operating lever 52 at least partially overlap along the second direction.

[0080] The fact that the vertical part 42 and the operating lever 52 at least partially overlap along the second direction should be understood as follows: when the vertical part 42 and the operating lever 52 are projected onto a certain plane along the second direction, the projections of the vertical part 42 and the operating lever 52 at least partially overlap. This at least partial overlap means that the vertical part 42 and the operating lever 52 can abut against each other along the second direction.

[0081] When the drive structure 50 is in the first position, the vertical part 42 abuts against the operating lever 52 in the second direction. At this time, the operating lever 52 can lock the pressing block 40 in a position away from the placement part 21.

[0082] The carrier 20 may be provided with a receiving groove 24. The main body 41 is located in the receiving groove 24 and is limited by the receiving groove 24 to move in the second direction. The first elastic member 30 is also located in the receiving groove 24. A cover plate 25 may also be connected to the carrier 20. When the cover plate 25 is connected to the carrier 20, the receiving groove 24 is closed to prevent the main body 41 from detaching from the receiving groove 24. The vertical part 42 extends out of the receiving groove 24 from the cover plate 25.

[0083] like Figure 1 , 8 As shown in Figure 9, the testing mechanism 300 also includes a test head 60 connected to the base 10, extending along a first direction. After the product 200 is placed in the placement part 21, the pusher 51 pushes the carrier 20 to move along the first direction, allowing the product 200 to dock with the test head 60 along the first direction. The test head 60 is electrically connected to the corresponding testing instrument. After the test head 60 and the product 200 are docked, the test head 60 and the product 200 are electrically connected, and the testing instrument can test various electrical properties of the product 200 through the test head 60.

[0084] Specifically, the test head 60 is equipped with multiple probes 61, and the product 200 is equipped with multiple mating parts (not shown in the figure). The mating of the test head 60 and the product 200 refers to the multiple probes 61 on the test head 60 mating with the multiple mating parts of the product 200 respectively. After the multiple probes 61 are mated with the multiple mating parts of the product 200 respectively, the test instrument can achieve electrical conductivity with the product 200.

[0085] As is conceivable, the first direction is aligned with the orientation of the mating portion on the product 200. Thus, when the carrier 20 moves along the first direction, the mating portion of the product 200 can align with the probe 61 on the test head 60. In the design of the transfer mechanism 100, the direction of movement of the carrier 20 is determined by the orientation of the mating portion. In this embodiment, the first and second directions are set at an angle to detect the product 200 with its mating portion tilted.

[0086] Continue to combine Figure 10-11 As shown, the product 200 in this embodiment is an electronic product 200. When testing the product 200, it is necessary to power the product 200. In this embodiment, a wireless charger 22 is provided on the carrier 20. When the product 200 is placed in the placement part 21, the wireless charger 22 can power the product 200.

[0087] The product 200 has a first opening 201 and a second opening 202 respectively, which are inclined on both sides along its length. When the product 200 is placed in the placement part 21 of the carrier 20, the second opening 202 extends along the first direction. When the test head 60 tests the product 200, the test head 60 enters the second opening 202 along the first direction. Specifically, multiple mating parts of the product 200 are located in the second opening 202. After the test head 60 enters the second opening 202, multiple probes 61 on it can respectively connect to multiple mating parts.

[0088] The first opening 201 and the second opening 202 are symmetrically arranged on both sides of the product 200 along its length. When the pressing block 40 presses against the product 200, the end of the pressing block 40 will extend into the first opening 201.

[0089] Both the first opening 201 and the second opening 202 penetrate the product 200 along its width direction. The carrier 20 is provided with two positioning posts 26. After the product 200 is placed in the placement part 21, the two positioning posts 26 can be inserted into the second opening 202 from both sides of the product 200 in the width direction. On this basis, the pressing block 40 presses against the product 200, which can effectively limit the position of the product 200.

[0090] The testing unit 300 may also include an indicator module 62 connected to the base 10. The indicator module 62 can display the test results of the product 200. By observing the indicator module 62, the operator can determine whether the product 200 is qualified.

[0091] The indicator module 62 includes multiple first indicator lights 621 of different colors. When the first indicator lights 621 of different colors are lit, they can indicate different test results of the product 200.

[0092] For example, the indicator module 62 includes three first indicator lights 621, which emit red, green, and yellow light respectively. When the red first indicator light 621 is lit, it indicates that the product 200 has failed the test; when the green first indicator light 621 is lit, it indicates that the product 200 has passed the test; and when the yellow first indicator light 621 is lit, it indicates that the product 200 has not been correctly placed in the placement section 21.

[0093] In some cases, the three indicator lights may emit the same color to indicate the test structure of product 200. For example, if all three indicator lights 621 emit red light, it means that product 200 has failed the test; if all three indicator lights 621 emit green light, it means that product 200 has passed the test; and if all three indicator lights 621 emit yellow light, it means that product 200 has not been correctly placed in the placement section 21.

[0094] As can be imagined, the indicator module 62 can also be designed in other ways, such as including a display screen that can display the test results of product 200.

[0095] Specifically, the testing mechanism 300 includes a first circuit board 12, an interface 13 electrically connected to the first circuit board 12, and multiple second indicator lights (not shown in the figure). The test head 60 is electrically connected to the first circuit board 12, and the interface 13 is used to electrically connect to an external processing unit. The processing unit can be electrically connected to the product 200 in sequence through the interface 13, the first circuit board 12, and the test head 60, thereby enabling testing of the product 200. The test results of the product 200 can be displayed through the multiple second indicator lights on the first circuit board 12.

[0096] The number of second indicator lights is the same as that of first indicator lights 621, and multiple first indicator lights 621 and multiple second indicator lights are set one-to-one. The corresponding first indicator lights 621 and second indicator lights are connected by optical fiber 14. That is, the light emitted by the second indicator light will be transmitted to the corresponding first indicator light 621 through optical fiber 14. The above-mentioned scheme of how multiple first indicator lights 621 display the test results of product 200 is the same as the scheme of how multiple second indicator lights display the test structure of product 200.

[0097] The multiple second indicator lights on the first circuit board 12 are small and located in positions that are not easily seen. In the above solution, multiple first indicator lights 621 corresponding to the second indicator lights are set in conspicuous positions, making it easier for operators to observe the test results of the product 200.

[0098] The testing mechanism 300 also includes a second circuit board 15. The second circuit board 15 and the test head 60 can be connected through components such as probes. The second circuit board 15 can also be connected to the first circuit board 12. Thus, the test head 60 is connected to the first circuit board 12 through the second circuit board 15.

[0099] The angle e between the first direction and the second direction can be 45°. Let A be the distance A that the push block 51 moves along the second direction when it pushes the carrier 20, and B be the distance B that the carrier 20 moves along the third direction. When the angle e between the first direction and the second direction is 45°, the ratio of A to B is 1. That is, the distance that the push block 51 pushes the carrier 20 to move along the second direction will be equal to the distance that the carrier 20 moves along the third direction. This makes it easier to accurately control the moving distance of the carrier 20.

[0100] As can be imagined, the smaller the angle 'e' between the first and second directions, the larger the ratio between the aforementioned distances A and B, and the smaller the thrust required for the pusher block 51 to push the carrier 20. For example, when the angle between the first and second directions is less than 45°, when the pusher block 51 pushes the carrier 20, the distance A that the pusher block 51 moves along the second direction is greater than the distance B that the carrier 20 moves along the third direction. Conversely, the larger the angle between the first and second directions, the smaller the ratio between the aforementioned distances A and B. Although the pusher block 51 can push the carrier 20 to move along the first direction more quickly, the thrust required for the pusher block 51 to push the carrier 20 is also greater. In the above setting, by setting the angle between the first and second directions to 45°, a balance can be achieved between the speed at which the pusher block 51 pushes the carrier 20 to move along the second direction and the thrust required for the pusher block 51 to push the carrier 20.

[0101] In other embodiments of the present invention, the first direction and the second direction may be the same direction. In this case, the carrier 20 does not tilt, and its direction of movement is the same as the direction in which the pusher 51 pushes it.

[0102] In this embodiment, the transfer mechanism 100 further includes a support 70 fixedly disposed on the base 10 and a second elastic member 71 connecting the support 70 and the carrier 20. The second elastic member 71 is elastically telescopically disposed along a first direction. The second elastic member 71 is used to drive the carrier 20 to reset. When the push block 51 pushes the carrier 20, the second elastic member 71 elastically deforms, thereby accumulating elastic potential energy. When the push block 51 retracts, the elastic potential energy of the second elastic member 71 is released, which can drive the carrier 20 to return to its initial position when it was not pushed by the push block 51 along the first direction, so that the product 200 can be tested again. Under the action of the second elastic member 71, the carrier 20 can be maintained in the initial position.

[0103] The second elastic element 71 enables the carrier 20 to automatically reset, improving the automation level of the transfer mechanism 100. Furthermore, the structure is simple, saving the manufacturing cost of the transfer mechanism 100.

[0104] In this embodiment, the second elastic element 71 is a tension spring, with its two ends connected to the support 70 and the carrier 20, respectively. When the push block 51 pushes the carrier 20 to move along the first direction, the tension spring is stretched. When the push block 51 retracts, the tension spring contracts, enabling the carrier 20 to return to its initial position along the first direction before being pushed by the push block 51.

[0105] It is conceivable that in other embodiments of the present invention, the second elastic element 71 may also be other elastic elements such as an elastic rope.

[0106] The transfer mechanism 100 also includes a drive member 80 that connects the drive structure 50 and the base 10, the drive member 80 being used to drive the drive structure 50 to a first position and a second position.

[0107] It should be noted that "driving member 80 is used to drive driving structure 50 to the first position and the second position" should be understood as driving member 80 to drive driving structure 50 to the first position and the second position, and to fix driving structure 50 in the first position and the second position.

[0108] Under the action of the driving component 80, when the driving structure 50 is in the first position, the push block 51 and the carrier 20 are separated by a predetermined distance d in the second direction, and the operating lever 52 contacts the pressing block 40, causing the pressing block 40 to move away from the placement part 21. At this time, the product 200 can be placed in the placement part 21. Under the action of the driving component 80, when the driving structure 50 is in the second position, the product 200 can maintain contact with the test head 60, so that the transfer mechanism can test the product 200. The driving component 80 improves the automation level of the transfer mechanism 100 and saves manpower.

[0109] In this embodiment, as Figure 3 , 5 As shown in Figures 6 and 12, the transfer mechanism 100 further includes a driving member 80, which drives the driving structure 50 to move relative to the base 10 along a second direction. The driving member 80 includes a driving section and an output section 81. The driving section is disposed on the base 10 and drives the output section 81 to move relative to the base 10 along the second direction. The output section 81 is connected to the driving structure 50, and its movement along the second direction enables the driving structure 50 to move along the second direction.

[0110] Specifically, the drive structure 50 is provided with a connecting groove 56, the output part 81 is movably connected to the drive structure 50 along the second direction, and includes a connector 811 located in the connecting groove 56. The dimension of the connecting groove 56 in the second direction is larger than the dimension of the connector 811 in the second direction, and the connector 811 can move in the second direction within the connecting groove 56.

[0111] Specifically, the drive structure 50 also includes a first contact surface 561 and a second contact surface 562 located on both sides of the connecting groove 56 in a second direction. The first contact surface 561 is close to the carrier 20, and the second contact surface 562 is away from the carrier 20. The first contact surface 561 and the second contact surface 562 are used to contact the connector 811, thereby enabling the connector 811 to drive the drive structure 50 to move. The connecting groove 56 is specifically formed on the push block 51.

[0112] The dimension of the connecting groove 56 in the second direction is larger than the dimension of the connector 811 in the second direction, meaning that the distance between the first contact surface 561 and the second contact surface 562 is greater than the dimension occupied by the connector 811 in the second direction. When the driving member 80 drives the driving structure 50 to move so that the push block 51 of the driving structure 50 can push the carrier 20 to move, the connector 811 contacts the first contact surface 561.

[0113] When the carrier 20 needs to be reset, the drive unit drives the output unit 81 to move away from the carrier 20 in the second direction. However, because the distance between the first contact surface 561 and the second contact surface 562 is greater than the size occupied by the connector 811 in the second direction, there is a gap between the connector 811 and the second contact surface 562. Therefore, the output unit 81 cannot drive the drive structure 50 to retract. Instead, the second elastic element 71 drives the carrier 20 to reset. During the reset process, the carrier 20 and the push block 51 remain in contact, and the connector 811 and the first contact surface 561 remain in contact. After the second elastic element 71 drives the carrier 20 back to its initial position, the carrier 20 no longer moves. Then, the output unit 81 continues to move away from the carrier 20 in the second direction, allowing the connector 811 to contact the second contact surface 562 and causing the push block 51 to disengage from the carrier 20 until a predetermined distance d separates the push block 51 from the carrier 20. During the process of the output section 81 driving the push block 51 to disengage from the carrier 20 until the push block 51 and the carrier 20 are separated by a predetermined distance d, the operating lever 52 moves with the push block 51, causing the pressing block 40 to move away from the placement section 21. After the pressing block 40 moves away from the placement section 21, the product 200 can be removed from the placement section 21.

[0114] As can be seen, through the above settings, during the reset process of the carrier 20, the pressing block 40 will continuously press against the product 200 until the carrier 20 is reset and its position is stable. Only then will the pressing block 40 disengage from the product 200. This prevents the product 200 from being unlocked prematurely and thus disengaging from the carrier 20.

[0115] The driving component 80 can be a manual driving component 80, an electric driving component 80, a pneumatic driving component 80, etc. In this embodiment, the driving component 80 is a manual driving component 80. The operator operates the manual driving component 80 to drive the driving structure 50 to move along the second direction. By setting the manual driving component 80, the transfer mechanism 100 does not need to be connected to an electric power source, a pressurized air source, or a corresponding control device, making the structure of the transfer mechanism 100 simpler.

[0116] Specifically, the drive unit includes a first link 82 and a second link 83. The first link 82 is rotatably connected to the base 10, one end of the third link is rotatably connected to the output unit 81, and the other end is rotatably connected to the first link 82. The end of the output unit 81 away from the second link 83 is connected to the drive structure 50.

[0117] As can be seen, the driving component 80 adopts a linkage structure. When the operator moves the first linkage 82, the output unit 81 can be driven to move in the second direction, thereby driving the driving structure 50 to move in the second direction. The driving component 80, which adopts a linkage structure, not only has the effect of saving effort, but also, through the "dead point" characteristic of the linkage structure, the driving structure 50 can be fixed in the first position and the second position. When the driving structure 50 is in the first position and the second position, the driving structure 50 cannot drive the output unit 81 to move. The driving structure 50 can only be driven to move by moving the first linkage 82.

[0118] The drive structure 50 also includes a connecting frame 53 and a connecting member 54. The operating lever 52 is connected to the connecting frame 53, and the connecting member 54 is connected to the connecting frame 53 and movably connected to the push block 51 along the second direction, allowing relative movement between the push block 51 and the connecting frame 53 along the second direction. The drive structure 50 also includes a third elastic member (not shown) disposed on the side of the push block 51 facing away from the carrier 20 in the second direction. The third elastic member elastically abuts against the push block 51 and the connecting frame 53 along the second direction. The third elastic member may be a compression spring and is sleeved around the connecting member 54.

[0119] The drive unit 80 is connected to the push block 51. When the drive unit 80 drives the push block 51 away from the carrier 20, the third elastic member elastically supports the push block 51 and the connecting frame 53. Therefore, the push block 51 will drive the connecting frame 53 and the operating rod 52 connected to the connecting frame 53 to move through the third elastic member. When the operating rod 52 moves, it can pull the pressing block 40, so that the pressing block 40 is away from the placement part 21. The third elastic member allows the connecting frame 53 to float relative to the push block 51 in the second direction, thereby preventing the operating rod 52 from pulling the pressing block 40 excessively and causing damage to the pressing block 40.

[0120] In this embodiment, as Figure 3 As shown, the drive structure 50 has a slot 55 extending in the second direction, and the base 10 has a limiting pin 11 located within the slot 55, which can move within the slot 55. The length of the slot 55 extending in the second direction determines the range of movement of the drive structure 50 relative to the base 10 in the second direction. The cooperation between the slot 55 and the limiting pin 11 can limit the range of movement of the drive structure 50.

[0121] An embodiment of the present invention also provides a product testing method, which includes the following steps:

[0122] Provide the aforementioned testing equipment 100;

[0123] The product 200 is placed on the carrier 20.

[0124] Product 200 is placed on carrier 20, that is, product 200 is placed in placement part 21. Before product 200 is placed on carrier 20, movable structure 102 is in second state.

[0125] The drive structure 50 is driven to move relative to the base 10 in the second direction. When the drive structure 50 moves relative to the base 10 in the second direction, the operating lever 52 first moves relative to the carrier 20 in the second direction so that the movable structure 102 is switched from the second state to the first state. Then, the push block 51 contacts the carrier 20 to push the carrier 20 to move in the first direction until the product 200 docks with the testing mechanism 300.

[0126] After the product 200 is placed on the carrier 20, the drive structure 50 is driven to move in the second direction. The push block 51 and the operating lever 52 can move synchronously. When the push block 51 has not yet contacted the carrier 20 and has not yet pushed the carrier 20 to move in the first direction, the operating lever 52 can move relative to the carrier 20, so that the movable structure 102 can switch from the second state to the first state, thereby limiting the position of the product 200 on the carrier 20. When the push block 51 contacts the carrier 20, the positions of the operating lever 52 and the carrier 20 remain fixed, and the push block 51 can push the carrier 20 to move in the first direction until the product 200 on the carrier 20 docks with the testing mechanism 300.

[0127] The product 200 was tested.

[0128] In the above steps, the carrier 20 has brought the product 200 into contact with the testing mechanism 300, and the position of the product 200 is also limited by the movable structure 102. At this time, the product 200 can be tested.

[0129] The product testing method for product 200 provided in this embodiment, during the process of driving the driving structure 50 to move along the second direction, when the push block 51 has not contacted the carrier 20, the operating lever 52 moves relative to the carrier 20 along the second direction, which can first cause the movable structure 102 to switch from the second state to the first state to limit the position of the product 200. Then, when the push block 51 contacts the carrier 20, it can drive the carrier 20 to move along the first direction. Two operations are completed in one action, which simplifies the structure of the transfer mechanism 100, reduces the number of parts required by the transfer mechanism 100, and reduces the manufacturing cost and control difficulty of the testing equipment 1000. The product testing method provided in this embodiment also includes the following steps:

[0130] After the product 200 test is completed, the drive structure 50 is driven away from the carrier 20 in the second direction until the push block 51 disengages from the carrier 20 in the second direction.

[0131] When the pusher 51 moves the carrier 20, the second elastic element 71 is stretched, accumulating elastic potential energy. After the product 200 is tested, the drive structure 50 is driven away from the carrier 20 along the second direction. The elastic potential energy of the second elastic element 71 is released, causing the carrier 20 to reset. Furthermore, the pusher 51 can move to a position where it is no longer in contact with the carrier 20, so that it can push the carrier 20 to move again. Therefore, by repeatedly moving the drive structure 50 along the second direction, multiple products 200 can be tested continuously, and the testing equipment 100 can efficiently test the products 200.
