[0033] like Figure 1 As shown, this embodiment provides a testing device, including a mobile platform 10, a clamping mechanism 20, a slide mechanism 30 and a guide mechanism 40, as follows:

[0034] like Figure 2 As shown, the mobile platform 10 is in the shape of a rectangular flat plate, and the mobile platform 10 is horizontally arranged, wherein the mobile platform 10 is movably arranged along a first horizontal direction, and there are at least two ways of movably arranging (the first way is illustrated in this embodiment):

[0035] The first one, such as Figure 2 As shown, two parallel first linear guide rails 11 are arranged on the ground or work surface, the length direction of the first linear guide rail 11 is configured as a first horizontal direction, and a first guide rail block is arranged at the bottom of the mobile platform 10, and the first guide rail block can be slidably matched with the first linear guide rail 11;

[0036] The second type is that a first roller groove is set on the ground or work surface, the length direction of the first roller groove is configured as a first horizontal direction, and a first walking roller is rollably set on the bottom of the mobile platform 10, and the first walking roller can roll and walk along the first horizontal direction in the first roller groove.

[0037] like Figure 2As shown, the testing device further includes a driving mechanism 70, which is connected to the mobile platform 10. The driving mechanism 70 can drive the mobile platform 10 to move in the first horizontal direction. The specific structural forms of the driving mechanism 70 include at least the following two forms (the first form is illustrated in this embodiment):

[0038] The first one, such as Figure 2 As shown, the driving mechanism 70 includes a servo motor 71 and a screw rod 72. The servo motor 71 is fixedly arranged, and the screw rod 72 is rotatably arranged. The axial direction of the screw rod 72 is configured as a first horizontal direction. One end of the screw rod 72 is connected to the output end of the servo motor 71, and the mobile platform 10 is threadedly matched with the screw rod 72.

[0039] Second, the driving mechanism 70 includes a telescopic cylinder, which is fixedly arranged, and a telescopic end of the telescopic cylinder is connected to the moving platform 10, and the telescopic direction of the telescopic cylinder is configured as a first horizontal direction.

[0040] It should be noted that, in this embodiment, the driving mechanism 70 may not be provided, and the mobile platform 10 may be manually driven to move, which is also a feasible approach.

[0041] like Figure 3 and Figure 4 As shown, the clamping mechanism 20 includes a mounting sleeve 21, a center column 22, a first reset member 23 and a clamping arm assembly 24, which are specifically as follows:

[0042] like Figure 3 and Figure 4 As shown, the mounting sleeve 21 is vertically arranged on the mobile platform 10, and the lower end of the mounting sleeve 21 is downwardly penetrated to the bottom of the mobile platform 10, and at least part of the structure of the lower end of the center column 22 (cylinder) is coaxially sleeved in the mounting sleeve 21, and the center column 22 can move up and down relative to the mounting sleeve 21 in the height direction, and the top of the center column 22 is provided with a first contact surface 22a, and the first contact surface 22a can cooperate with the guide mechanism 40 (specifically the first guide rail 41), so that the center column 22 is stressed and moves downward; the first reset member 23 (such as a spring) is coaxially sleeved on the center column 22, and the first reset member 23 (such as a spring) is coaxially sleeved on the center column 22. The lower end of the positioning member 23 abuts against the upper end surface of the mounting sleeve 21, and the upper end of the first reset member 23 can directly or indirectly abut against the center column 22, and the length direction (i.e., the telescopic direction) of the first reset member 23 is configured as the height direction. The center column 22 is driven by the first reset member 23 to perform a reset movement upward, so that the pressure arm assembly 24 is out of contact with the product 50 to be tested. When the product 50 needs to be pressed, the center column 22 overcomes the elastic force of the first reset member 23 and moves downward; the pressure arm assembly 24 is arranged on the outer circumference of the center column 22, and is used to press the product 50 to be tested on the moving platform 10 downward.

[0043] like Figure 3 As shown, the pressure arm assembly 24 includes a rotating arm 241, a pressure block 242 and a first elastic member 243 (such as a spring). The middle position of the rotating arm 241 is fixedly connected to the outer circumference of the central column 22. The pressure block 242 is arranged at the end of the rotating arm 241 along the height direction. The pressure block 242 can slide up and down relative to the rotating arm 241. The lower surface of the pressure block 242 is parallel to the horizontal plane. The pressure block 242 is used to contact the upper surface of the product 50 and press the product 50. The first elastic member 243 is coaxially sleeved on the pressure block 242, and the lower end of the first elastic member 243 is against the pressure block 242, and the upper end of the first elastic member 243 is against the rotating arm 241. The telescopic direction of the first elastic member 243 is configured as the height direction. In this embodiment, the first elastic member 243 is provided to prevent the pressure block 242 from crushing the product 50, and on the other hand, it can prevent the rigid contact between the pressure block 242 and the product 50 from causing damage to the product 50.

[0044] Please refer again Figure 1 and Figure 2 As shown, in some preferred embodiments, along the first horizontal direction, multiple clamping mechanisms 20 and multiple slide mechanisms 30 are arranged at intervals on the mobile platform 10; along the second horizontal direction, a slide mechanism 30 is arranged on both sides of each clamping mechanism 20, and a product 50 to be tested is arranged between the clamping mechanism 20 and the slide mechanism 30. In this embodiment, the multiple clamping mechanisms 20 and slide mechanisms 30 can simultaneously meet the testing work of multiple products 50, thereby realizing large-scale production testing, wherein each clamping mechanism 20 corresponds to a total of two products 50 and two slide mechanisms 30 on the left and right, and the clamping mechanism 20 can simultaneously clamp the products 50 on its left and right sides under the guidance of the guide mechanism 40, with a high degree of automation. Among them, the first horizontal direction and the second horizontal direction intersect vertically in the horizontal plane.

[0045] like Figure 3 As shown, two pressing blocks 242 are disposed on the rotating arm 241 of the pressing mechanism 20 . The two pressing blocks 242 are respectively located at two ends of the length direction of the rotating arm 241 . A first elastic member 243 is correspondingly disposed on each pressing block 242 .

[0046] like Figure 3 As shown, a spiral guide groove 211 is provided on the outer peripheral wall of the mounting sleeve 21, and a rotary follower bearing 221 is provided on the outer periphery of the center column 22. The axial direction of the rotary follower bearing 221 is configured in a horizontal direction, and at least a part of the rotary follower bearing 221 is penetrated in the spiral guide groove 211. Through the cooperation of the spiral guide groove 211 and the rotary follower bearing 221, when the center column 22 moves downward, the rotating arm 241 can be horizontally rotated to the top of the product 50 and pressed against the product 50.

[0047] like Figure 3As shown, in this embodiment, the outer circumferential surface of the rotary follower bearing 221 can roll in contact with the inner circumferential wall of the spiral guide groove 211 to ensure smooth rotation and downward sliding of the center column 22. When the product 50 needs to be released, as long as the first contact surface 22a at the upper end of the center column 22 is out of contact with the guide rail mechanism (specifically the first guide rail 41), the center column 22 will move upward under the drive of the first reset member 23. At the same time, due to the guiding effect of the spiral guide groove 211, the center column 22 will rotate synchronously during the upward reset process, thereby allowing the pressure block 242 above the product 50 to release the height limit on the product 50.

[0048] like Figure 3 As shown, in some preferred embodiments, the spiral guide groove 211 includes a spiral segment 211a and a straight segment 211b that are interconnected, the spiral segment 211a is located above the straight segment 211b, the spiral segment 211a is spirally arranged on the outer peripheral wall of the mounting sleeve 21 along the axial direction of the mounting sleeve 21, and the length direction of the straight segment 211b is consistent with the axial direction of the mounting sleeve 21, and the rotary follower bearing 221 can roll in the spiral segment 211a and the straight segment 211b, wherein the spiral segment 211a cooperates with the rotary follower bearing 221 to realize that the center column 22 synchronously drives the rotating arm 241 to rotate during the downward movement, and the straight segment 211b enables the pressing block 242 on the rotating arm 241 to rotate to the top of the product 50 after the pressing block 242 can Keep vertical downward movement and press against the upper surface of the product 50. Specifically, when the rotary follower bearing 221 is in the transition position between the spiral segment 211a and the straight segment 211b, the pressing block 242 just rotates to the top of the product 50 to be tested. Then, as the center column 22 continues to move downward, the pressing block 242 vertically contacts the product 50. The purpose of this design is to prevent the pressing block 242 from bringing a horizontal component of force to the product 50. If the pressing block 242 brings a horizontal component of force to the product 50, it will cause the pin to break or the product 50 to be damaged. Therefore, the straight segment 211b and the rotary follower bearing 221 are designed to cooperate to limit the pressing block 242 to only be able to move linearly downward within the stroke of this straight segment 211b, and no horizontal component of force will be generated. It should be noted that the transition position between the spiral segment 211a and the straight segment 211b refers to the position shared by the tail end of the spiral segment 211a and the top of the straight segment 211b, such as Figure 3 As shown in the mark P.

[0049] like Figure 3As shown, in some preferred embodiments, the clamping mechanism 20 also includes an end ball bearing 25; the end ball bearing 25 is coaxially sleeved on the outer periphery of the center column 22, the upper end of the first reset member 23 is against the lower end surface of the end ball bearing 25, and the lower surface of the rotating arm 241 is connected to the upper end surface of the end ball bearing 25. By providing the end ball bearing 25, the friction between the rotating arm 241 and other components can be reduced, thereby ensuring the rotation performance of the rotating arm 241.

[0050] like Figure 3 As shown, in some preferred embodiments, the top of the center column 22 is provided with a terminal head 222, the terminal head 222 is located directly above the rotating arm 241, and a spherical surface is provided at the center of the terminal head 222, and the spherical surface is configured as a first contact surface 22a that can contact the guide mechanism 40 (specifically, the first guide rail 41), wherein at least part of the spherical surface protrudes upward above the terminal head 222, and the spherical surface and the terminal head 222 can be fixed or relatively rotatable. In this embodiment, configuring the first contact surface 22a as a spherical surface can make the contact between the center column 22 and the first guide rail 41 smoother and more flexible, which is convenient for guiding the center column 22 to move downward and avoiding obstruction of the rotation of the center column 22.

[0051] like Figure 5 As shown, the slide mechanism 30 includes a slide 31, a horizontal thrust assembly 32 and a second reset member 33, which are specifically as follows:

[0052] The slide 31 is movably disposed on the mobile platform 10 along the second horizontal direction, wherein there are at least two ways in which the slide 31 is movably disposed on the mobile platform 10 (the first way is illustrated in this embodiment):

[0053] The first one, such as Figure 5 As shown, a second linear guide rail 311 is provided on the mobile platform 10, the length direction of the second linear guide rail 311 is configured as a second horizontal direction, and a second guide rail block slidably matched with the second linear guide rail 311 is provided on the lower surface of the slide 31;

[0054] The second type is that a second roller groove is set on the mobile platform 10, and the length direction of the second roller groove is configured as a second horizontal direction. A second walking roller is rollably set at the bottom of the slide 31, and the second walking roller can roll and walk in the second roller groove along the second horizontal direction.

[0055] like Figure 6As shown, along the second horizontal direction, an installation station is provided on one side of the slide 31 close to the clamping mechanism 20, and the product 50 to be tested is placed on the installation station. A first travel switch 35 is provided in the installation station. After the product 50 to be tested is placed on the installation station, the control rod of the first travel switch 35 is compressed and generates a signal to prompt an external person that the product 50 is installed in place, and there is also a vertically upward positioning pin 36 on the installation station, which can cooperate with the positioning hole on the product 50 to achieve the positioning of the product 50. A second travel switch 37 corresponding to the slide 31 is also provided on the mobile platform 10, and the second travel switch 37 can detect whether the slide 31 is reset in place.

[0056] like Figures 7 to 9 As shown, a pin assembly 60 is arranged on the slide 31; the slide 31, the pin assembly 60, the product 50 to be tested and the clamping mechanism 20 are arranged in sequence in the second horizontal direction, and the four are arranged flush in the second horizontal direction; the pin assembly 60 is used to perform power-on test on the product 50.

[0057] like Figure 7 and Figure 8 As shown, the pin assembly 60 includes a connecting block 61, a floating block 62, an elastic twist head 63 and a test pin 64; along the second horizontal direction, a connecting ear 611 is provided on the side of the connecting block 61 away from the product 50, and an ear hole is provided on the connecting ear 611, and a first plug hole is provided on the slide 31, and the connecting ear 611 is inserted into the first plug hole along the second horizontal direction, and a second plug hole connected to the first plug hole is provided on one side of the slide 31 along the first horizontal direction, and a first pin 65 is inserted into the second plug hole and connected with the ear hole, and a stable connection between the connecting block 61 and the slide 31 is achieved through the first pin 65; a second pin 66 extending toward the product 50 is provided on the side of the connecting block 61 facing the product 50, and the outer circumferential clearance of the floating block 62 and the second pin 66 is matched, so that the floating block 62 can float at various angles; the two ends of the elastic twist head 63 are respectively connected to the connecting block 61 and the floating block 62; the test pin 64 is provided on the floating block 62, and the test pin 64 can be inserted into the product 50 to achieve power-on test. The cooperation between the floating block 62 and the second pin 66 of this embodiment allows the floating block 62 to float in all directions, up, down, left, and right. The elastic twist head 63 (elastic material) makes the floating of the floating block 62 have a certain damping effect, that is, the floating of the floating block 62 is elastic floating, and the floating block 62 can adapt to the situation where there is a certain position deviation between the self-adapting pin and the product 50, thereby improving the overall flexibility of the device. On the other hand, the connection between the connecting block 61 and the slide 31 using the first pin 65 can facilitate the rapid replacement of the pin assembly 60.

[0058] like Figure 7 and Figure 8As shown, the transverse push assembly 32 is arranged on one side of the slide 31, and a second contact surface 32a for contacting the guide mechanism 40 (specifically the second guide rail 42) is provided on the transverse push assembly 32. The guide mechanism 40 contacts the second contact surface 32a, and guides the transverse push assembly 32 and the slide 31 to gradually approach the product 50 in the second horizontal direction, so that the pin assembly 60 on the other side of the slide 31 is inserted into the product 50, thereby realizing the electrical connection between the pin assembly 60 and the product 50.

[0059] like Figure 7 and Figure 8 As shown, the transverse push assembly 32 includes a first guide column 321, a transverse push block 322, a guide wheel 323 and a second elastic member 324 (such as a spring); the first guide column 321 is slidably arranged on the slide 31 along the second horizontal direction, the transverse push block 322 is arranged at one end of the first guide column 321 away from the slide 31, and the guide wheel 323 is rotatably arranged at the lower end of the transverse push block 322, the axial direction of the guide wheel 323 is configured as the height direction, and the outer circumferential surface of the guide wheel 323 is configured as a second contact surface 32a that can contact the guide mechanism 40 (specifically the second guide rail 42), and the guide wheel 323 cooperates with the guide mechanism 40 to guide the slide 31 to gradually approach the product 5 in the second horizontal direction. 0, the second elastic member 324 is coaxially sleeved on the first guide column 321, one end of the second elastic member 324 is against the side of the slide 31, and the other end is against the horizontal push block 322, and the telescopic direction of the second elastic member 324 is configured as a second horizontal direction. When the guide wheel 323 and the guide mechanism 40 are in contact, the second elastic member 324 is compressed, and the reset force of the second elastic member 324 drives the slide 31 to have a tendency to approach the product 50. By setting the second elastic member 324, on the one hand, it can avoid the rigid contact between the pin assembly 60 on the slide 31 and the product 50, and on the other hand, it can avoid the reaction force of the first guide rail 41 to damage the overall structure, which can improve the overall flexibility of the device.

[0060] like Figure 5 As shown, one end of the second reset member 33 (such as a spring) is connected to the mobile platform 10, and the other end is connected to the slide 31. The length direction of the second reset member 33 is configured as the second horizontal direction. When the slide 31 gradually approaches the product 50, the second reset member 33 is compressed. When the guide mechanism 40 (specifically the second guide rail 42) is out of contact with the guide wheel 323, the second reset member 33 can drive the slide 31 to move away from the product 50 and reset, and at the same time, the pin assembly 60 and the product 50 are out of contact. In some preferred embodiments, the mobile platform 10 is provided with a second guide column 34 extending along the second horizontal direction. The outer circumference of the second guide column 34 is slidably matched with the slide 31. The second guide column 34 can guide the movement of the slide 31 in the second horizontal direction to ensure the movement accuracy; the second reset member 33 is coaxially sleeved on the second guide column 34.

[0061] like Figure 1 , Fig.10 and Fig.11 As shown, the guide mechanism 40 includes a first guide rail 41 and a second guide rail 42, and the length directions of the first guide rail 41 and the second guide rail 42 are both configured as a first horizontal direction, as follows:

[0062] like Figure 1 and Fig.10 As shown, the first guide rail 41 is located directly above the clamping mechanism 20, and a first guide slope 41a is provided at one end of the first guide rail 41 close to the mobile platform 10. From the perspective of the second horizontal direction, a first predetermined angle θ is formed between the first guide slope 41a and the first horizontal direction, and the range of the first predetermined angle θ is between 10 degrees and 30 degrees, for example, 10 degrees, 15 degrees or 20 degrees; during the movement of the mobile platform 10, the first guide slope 41a can contact the first contact surface 22a at the top of the center column 22, and the slope design of the first guide slope 41a enables the center column 22 to be gradually pressed downward and eventually the pressing block 242 is pressed against the product 50. In some preferred embodiments, the first guide rail 41 further includes a first retaining surface 41b capable of contacting the first contact surface 22a, the first retaining surface 41b is connected to the first guide slope 41a, the first retaining surface 41b is arranged parallel to the first horizontal direction, and the first retaining surface 41b is flush with the lowest end of the first guide slope 41a; along the first horizontal direction, the first retaining surface 41b is located on the side of the first guide slope 41a away from the mobile platform 10. In this embodiment, when the center column 22 is guided by the first guide slope 41a and moves downward, the pressing block 242 on the center column 22 is pressed against the upper surface of the product 50. As the mobile platform 10 continues to move, the first contact surface 22a at the top of the center column 22 passes the first guide slope 41a and enters the area of ​​the first retaining surface 41b. The first retaining surface 41b can keep the center column 22 in a pressed state, so that the pressing block 242 continues to press the product 50 during the test.

[0063] like Figure 1 and Fig.11As shown, the second guide rail 42 is located on one side of the slide mechanism 30 (specifically the guide wheel 323), and along the second horizontal direction, the second guide rail 42 is located on the side of the guide wheel 323 away from the slide 31; the second guide rail 42 and the guide wheel 323 are at the same horizontal height. In this embodiment, a total of two second guide rails 42 are provided; in the second horizontal direction, the two second guide rails 42 are respectively located on both sides of the mobile platform 10, one second guide rail 42 is used to cooperate with one row of slide mechanisms 30, and the other second guide rail 42 is used to cooperate with another row of slide mechanisms 30. From a top view, a second guide slope 42a is provided at one end of the second guide rail 42 close to the movable platform 10, and the second guide slope 42a has a second predetermined angle β with the first horizontal direction, and the range of the second predetermined angle β is between 15 degrees and 40 degrees, for example, 15 degrees or 20 degrees; during the movement of the movable platform 10, the second guide slope 42a can contact the second contact surface 32a of the guide wheel 323 (that is, the outer circumferential surface of the guide wheel 323). Due to the slope design of the second guide slope 42a, the guide wheel 323 and the transverse push block 322 are pushed inward, and the second elastic member 324 that is against the transverse push block 322 is subjected to the force of the transverse push block 322, so that the second elastic member 324 pushes the slide 31 toward the product 50 (while compressing the second reset member 33), and the pin assembly 60 on the slide 31 is then inserted into the product 50 to realize the power-on test. In some preferred embodiments, the second guide rail 42 further includes a second retaining surface 42b capable of contacting the second contact surface 32a, the second retaining surface 42b is connected to the second guide slope 42a, and the second retaining surface 42b is arranged perpendicular to the second horizontal direction; along the first horizontal direction, the second retaining surface 42b is located on the side of the second guide slope 42a away from the mobile platform 10, and the second retaining surface 42b is flush with the end of the second guide slope 42a away from the mobile platform 10. In this embodiment, after the guide wheel 323 and the slide 31 and other components are guided by the second guide slope 42a and move toward the product 50, as the mobile platform 10 continues to move, the second contact surface 32a of the guide wheel 323 passes the second guide slope 42a and enters the area of ​​the second retaining surface 42b, and the second retaining surface 42b can limit the slide 31 and the position of the pin assembly 60 on the slide 31, so that the pin assembly 60 continues to maintain a connection state with the product 50 during the test process.

[0064] like Figure 2As shown, in some preferred embodiments, the first guide rail 41 protrudes a short distance toward the mobile platform 10 compared to the second guide rail 42, and a first guide slope 41a is provided on the protruding portion of the first guide rail 41, wherein, along the first horizontal direction, the mobile platform 10, the first guide slope 41a and the second guide slope 42a are arranged in sequence, and the first guide slope 41a is closer to the mobile platform 10 than the second guide slope 42a, so that the clamping mechanism 20 on the mobile platform 10 can first contact the first guide slope 41a, and then the guide wheel 323 on the slide mechanism 30 contacts the second guide slope 42a, so that a workflow of first clamping and then plugging in electricity can be realized.

[0065] A working method of the test device of this embodiment is as follows:

[0066] 1. Install the products 50 to be tested on the mobile platform 10 one by one;

[0067] 2. The driving mechanism 70 drives the mobile platform 10 to move along the first horizontal direction toward the first guide rail 41 and the second guide rail 42;

[0068] 3. During the movement of the mobile platform 10, the first contact surface 22a at the top of the center column 22 contacts the first guide slope 41a of the first guide rail 41, and the center column 22 compresses the first reset member 23 and moves downward. During the downward movement, the center column 22 simultaneously drives the rotating arm 241 to rotate, and the two pressing blocks 242 on the rotating arm 241 rotate to the top of the two products 50 respectively. As the mobile platform 10 continues to move, the center column 22 drives the pressing blocks 242 to press the products 50 downward and maintain the pressed state;

[0069] 4. After the pressing block 242 presses the product 50, the mobile platform 10 continues to move forward along the first horizontal direction, the second contact surface 32a (i.e., the outer circumferential surface) of the guide wheel 323 contacts the second guide inclined surface 42a of the second guide rail 42, and the slide 31 is pushed toward the product 50. The pin assembly 60 on the slide 31 is inserted into the product 50 along the second horizontal direction and the power-on test is realized;

[0070] 5. After the mobile platform 10 moves to the predetermined position, all the pin assemblies 60 are correspondingly inserted into the product 50 for testing. After the test is completed, the mobile platform 10 gradually returns to its original position. During the process of returning the mobile platform 10, the guide wheel 323 firstly breaks away from the contact with the second guide inclined surface 42a, and then the slide 31 quickly returns to its original position under the action of the second return member 33, and the pin assembly 60 immediately breaks away from the contact with the product 50.

[0071] 6. After the pin assembly 60 is out of contact with the product 50, the first contact surface 22a at the top of the center column 22 begins to contact the first guide slope 41a and gradually moves relative to the direction of disengagement. The center column 22 is reset upward under the action of the first reset member 23. During the upward reset process of the center column 22, the spiral guide groove 211 cooperates with the rotary follower bearing 221 to make the center column 22 rotate synchronously, and the pressing block 242 then rotates to make room above the product 50, making it easier to remove the product 50 from the mobile platform 10.
