[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, the carrier 100 is used to cooperate with the detection module to realize the pressure-fitting needle test on the circuit board to be tested, wherein the two test heads of the detection module can move relative to the carrier 100 along a first direction to perform needle testing on the circuit board to be tested on the carrier 100.

[0036] During operation, the circuit board to be tested is placed in the corresponding material tray 200, and then the material tray 200 is placed on the carrier 100. The two test heads of the detection module are respectively located on both sides of the material tray 200 in the first direction. When pressing and piercing, the two test heads move close to the material tray 200, and finally the circuit board to be tested in the material tray 200 is tested. Specifically, one test head is used to support the material tray 200, and the other test head is used to electrically contact the detection point of the circuit board to be tested in the material tray 200. In addition, the detection module and the detection operation of the detection module on the circuit board to be tested in the material tray 200 on the carrier 100 can be existing technologies, and this embodiment will not be described in detail here.

[0037] The circuit board to be tested may be a PCB, an FPC, etc.

[0038] like Figures 1 to 3As shown, the carrier 100 includes a bearing module 1, a first driving module 2 and a buffer module 3; the bearing module 1 is used to bear the material tray 200; the first driving module 2 is connected to the bearing module 1, and is used to drive the bearing module 1 to move along the second direction and / or the third direction to adjust the position of the bearing module 1 relative to the test module; the bearing module 1 can move in the first direction relative to the first driving module 2; the buffer module 3 is arranged between the bearing module 1 and the driving module, and is used to buffer the movement of the bearing module 1 along the first direction relative to the first driving module 2; wherein, the angle between the first direction and the second direction is greater than 0 degree and less than 180 degrees, the angle between the first direction and the third direction is greater than 0 degree and less than 180 degrees, and the angle between the second direction and the third direction is greater than 0 degree and less than 180 degrees.

[0039] During testing, multiple circuit boards to be tested can be placed in the material tray 200, wherein the number of circuit boards to be tested by the detection module each time can be less than the total number of circuit boards to be tested placed in the material tray 200, and the detection module can detect the circuit boards to be tested in the material tray 200 in multiple times until all the circuit boards to be tested in the material tray 200 are detected.

[0040] In this embodiment, the carrier 100 can drive the material tray 200 to move in the second direction and / or the third direction to adjust the phase position of the material tray 200 relative to the detection module, so that the two test heads of the detection module only need to move in the first direction to realize the detection of different circuit boards to be tested each time, and there is no need for the two test heads of the detection module to move in the second direction and / or the third direction.

[0041] Due to the heavy weight of the test head, if the material tray 200 does not move in the second direction and / or the third direction, but drives the two test heads to move in the second direction and / or the third direction, the control accuracy of the test head movement is low, making it easier for the two test heads to have misalignment problems in the second direction and / or the third direction. During the press-fit test, the material tray 200 is subjected to uneven force, making it easy for the material tray 200 to be deformed and damaged due to the unbalanced torque. Moreover, when the material tray 200 is deformed due to uneven force, it is also easy to cause the test head and the circuit board to be tested on the material tray 200 to be misaligned, thereby reducing the detection accuracy.

[0042] Through the arrangement of this embodiment, there is no need for the two test heads of the detection module to move in the second direction and / or the third direction, so as to realize the pressing test of the circuit board to be tested on the material tray 200, thereby effectively avoiding the problem of inaccurate alignment of the two test heads in the second direction and / or the third direction, and providing a guarantee for the balanced force of the material tray 200 during the pressing test, thereby effectively avoiding deformation and damage of the material tray 200 due to unbalanced torque, thereby increasing the service life of the material tray 200 and facilitating improving the detection accuracy of the circuit board to be tested.

[0043] In addition, in the present embodiment, the support module for supporting the placement of the material tray 200 can also move in the first direction, and the buffer module 3 can buffer the movement of the support module along the first direction, so the material tray 200 placed on the support module can also move in the first direction and be buffered by the buffer module 3. When the two test heads move along the first direction for the pressing test, the material tray 200 can float in the first direction to reduce the impact force on the material tray 200 in the first direction, reduce the problem of uneven force on the material tray in the first direction, avoid deformation and damage of the material tray 200, increase the service life of the material tray 200, and help to improve the detection accuracy of the circuit board to be tested.

[0044] In a feasible implementation, the first direction is a vertical direction, the first direction is perpendicular to the second direction, the first direction is perpendicular to the third direction, and the second direction is perpendicular to the third direction, that is, the second direction and the third direction are both horizontal directions.

[0045] In addition, preferably, the first driving module 2 can drive the bearing module 1 to move in the second direction and can also drive the bearing module 1 to move in the third direction. Of course, in actual scenarios, the first driving module 2 can only drive the bearing module 1 to move in the second direction or only drive the bearing module 1 to move in the third direction.

[0046] like Figure 1 As shown, in one embodiment, the first driving module 2 includes a first driving module 21 and a second driving module 22, wherein the second driving module 22 is connected to the first driving module 21, and the carrier module 1 is connected to the second driving module 22.

In addition, the first driving module 21 also includes a first guiding mechanism, which is used to guide the movement of the first bearing member along the second direction.

[0048] The first driving member includes a first motor and a first screw mechanism, wherein the first motor and the first screw mechanism are both connected to the base, the main shaft of the first motor is connected to the screw of the first screw mechanism, the first bearing member is connected to the nut of the first screw mechanism, and the first motor drives the first bearing member to reciprocate along the second direction through the first screw mechanism. The first bearing member can be a plate-like structure.

[0049] like Figure 2 and Figure 4 As shown, the second driving module 22 includes a second driving member and a second bearing member 221. The second driving member is mounted on the first bearing member and connected to the second bearing member 221. The bearing module 1 is connected to the second bearing member 221. The second driving member is used to drive the second bearing member 221 to reciprocate along the third direction, thereby driving the bearing module 1 to reciprocate along the third direction.

[0050] The second driving member includes a second motor and a second screw mechanism, wherein the second motor and the second screw mechanism are both connected to the base, the main shaft of the second motor is connected to the screw of the second screw mechanism, the second supporting member 221 is connected to the nut of the second screw mechanism, and the second motor drives the second supporting member 221 to reciprocate along the second direction through the second screw mechanism.

[0051] like Figure 2 As shown, in one embodiment, the second bearing member 221 includes a first bearing plate 222 and a second bearing plate 223, the first bearing plate 222 is connected to the second driving member, specifically, the first bearing plate 222 is connected to the threaded connection of the second screw mechanism, the second bearing plate 223 is connected to the first bearing plate 222, and the two are connected to form an L-shaped structure, wherein the first bearing plate 222 and the second bearing plate 223 can be vertically arranged. The bearing module 1 is installed on the second bearing plate 223.

[0052] like Figure 4 As shown, the bearing module 1 may be connected to the first driving module 2 via a guide module 4, and the guide module 4 is used to guide the movement of the bearing module 1 along a first direction relative to the first driving module 2. The guide module 4 may include two guide rail mechanisms, wherein the guide rails of the two guide rail mechanisms are both connected to the first driving module 2, and the bearing module 1 is respectively connected to the sliders of the two guide rail mechanisms.

[0053] The bearing module 1 is actually connected to the second bearing member 221 through the guide module 4. Specifically, the guide rails of the two guide rail mechanisms are connected to the second bearing plate 223 and are spaced apart along the second direction. The two guide rails extend along the first direction. As described below, the support plate 111 of the bearing module 1 is connected to the sliders of the two guide rail mechanisms.

[0054] like Figure 5As shown, in one embodiment, the buffer module 3 includes a first support block 31, a second support block 32, a guide column 33 and an elastic member; the first support block 31 and the second support block 32 are spaced apart along the first direction, wherein the first support block 31 is connected to the bearing module 1, the second support block 32 is connected to the first driving module 2, and the guide column 33 is connected to one of the first support block 31 and the second support block 32; the two ends of the elastic member respectively abut against the first support block 31 and the second support block 32; the elastic member has a avoidance hole extending along the first direction, and the guide column 33 is penetrated in the avoidance hole.

[0055] The expansion and contraction of the elastic member can be guided by the guide post 33. The elastic member can be a spiral spring, and at this time, the spring hole is an avoidance hole.

[0056] In addition, the second supporting block 32 may be mounted on the second supporting plate 223 .

[0057] It should be understood that if the guide column 33 is connected to the first support block 31, when the supporting module 1 moves relative to the first driving module 2 along the first direction, the guide column 33 and the second support block 32 can also generate relative movement in the first direction; if the guide column 33 is connected to the second support block 32, when the supporting module 1 moves relative to the first driving module 2 along the first direction, the guide column 33 and the first support block 31 can also generate relative movement in the first direction.

[0058] In one embodiment, one of the first support block 31 and the second support block 32 is connected to the guide column 33, and one of the first support block 31 and the second support block 32 is provided with a guide hole, and the guide column 33 is inserted into the guide hole so as to guide the guide column 33 through the hole wall of the guide hole. Specifically, when the guide column 33 is connected to the first support block 31, the second support block 32 is provided with a guide hole, and at this time, the movement of the guide column 33 relative to the second support block 32 in the first direction can be guided by the hole wall of the guide hole; when the guide column 33 is connected to the second support block 32, the first support block 31 is provided with a guide hole, and at this time, the movement of the guide column 33 relative to the first support block 31 in the first direction can be guided by the hole wall of the guide hole.

[0059] exist Figure 3 In the illustrated embodiment, the guide post 33 is connected to the second support block 32, and the guide hole is provided on the first support block 31. In addition, the guide hole penetrates the first support block 31 along the first direction. The guide post 33 extends from a side of the first support block 31 close to the second support block 32 to a side of the first support block 31 away from the second support block 32.

[0060] In addition, the buffer module 3 also includes a limit member 34, which is connected to the guide column 33. When the guide column 33 moves relative to the first support block 31 along the direction from the first support block 31 to the second support block 32 (in fact, the first support block 31 moves and the guide column 33 is stationary), the first support block 31 can interfere with the limit member 34.

[0061] In addition, the first support block 31 may be located above the second support block 32 . Initially, the elastic member supports the carrying module 1 . When the carrying module 1 is subjected to downward pressure, the elastic member may buffer the carrying module 1 .

[0062] In other embodiments, the two ends of the elastic member may also be connected to the first support block 31 and the second support block 32 respectively, so that when the supporting module 1 moves upward, it can also be buffered by the elastic member.

[0063] like Figure 2 As shown, in one embodiment, the bearing module 1 includes a support assembly 11, a clamping drive assembly 12, a first clamping block 13 and a second clamping block; the support assembly 11 is connected to the first drive module 2, the clamping drive assembly 12 is connected to the support assembly 11, and is respectively connected to the first clamping block 13 and the second clamping block; the clamping drive assembly 12 is used to drive the first clamping block 13 and the second clamping block to move, so that the first clamping block 13 and the second clamping block can clamp or release the material tray 200. Specifically, when the first clamping block 13 and the second clamping block are close to each other, the material tray 200 can be clamped to achieve the fixation of the material tray 200; when the first clamping block 13 and the second clamping block are away from each other, the material tray 200 can be released to release the fixation of the material tray 200.

[0064] like Figure 2 As shown, in one embodiment, the support assembly 11 includes a support member 111, a first support arm 112 and a second support arm 113; the clamping drive assembly 12 includes a first clamping drive member 121 and a second clamping drive member; the support member 111 is connected to the first drive module 2, and the first support arm 112 and the second support arm 113 are arranged on the support member 111 at intervals along the second direction; the first clamping drive member 121 is connected to the first support arm 112 and connected to the first clamp block 13; the second clamping drive member is connected to the second support arm 113 and connected to the second clamp block; the first clamping drive member 121 is used to drive the first clamp block 13 to move, and the second clamping drive member is used to drive the second clamp block to move. In addition, the two test heads of the detection module can perform a press-fit detection on the circuit board to be tested on the tray 200 clamped by the first clamp block 13 and the second clamp block from between the first support arm 112 and the second support arm 113.

[0065] In one embodiment, the first clamp 13 is connected to the first support arm 112 and can rotate relative to the first support arm 112 around a first axis, and the first axis is parallel to a third direction; the second clamp is connected to the second support arm 113 and can rotate relative to the second support arm 113 around a second axis, and the second axis is parallel to the third direction; the first clamping drive 121 is used to drive the first clamp 13 to rotate around the first axis, and the second clamping drive is used to drive the second clamp to rotate around the second axis.

[0066] Specifically, the first clamping driving member 121 includes a driving unit 122, a push rod 123, a roller 124 and a reset member; the driving unit 122 is connected to the first support arm 112 and is connected to the push rod 123 to drive the push rod 123 to reciprocate linearly along the third direction; the roller 124 is connected to the push rod 123 and can rotate relative to the push rod 123 around its own axis, the axis of the roller 124 is parallel to the first direction, the side of the roller 124 can contact the first clamping block 13, the upper end of the first clamping block 13 is rotatably connected to the first support arm 112, and the reset member is located at the first support arm 112 away from the second support On one side of the support arm 113, the reset member is compressed between the first support arm 112 and the first clamping block 13, the roller 124 is located on the side of the first clamping block 13 away from the first support arm 112, and the surface of the first clamping block 13 away from the contact with the roller 124 is an inclined surface (that is, the surface of the first clamping block 13 away from the first support arm 112 is an inclined surface, and the inclined surface is defined as the first inclined surface 131), wherein the first inclined surface is inclined along the third direction, specifically, along the positive direction of the third direction (that is, along the direction from the support member 111 to the first support arm 112), the first inclined surface 131 gradually moves away from the first support arm 112.

[0067] Under the elastic force of the reset member, the roller 124 keeps in contact with the first inclined surface 131. When the roller 124 moves along the positive direction of the third direction with the push rod 123, the roller 124 can apply pressure toward the first support arm 112 to the first clamping block 13, so that the first clamping block 13 rotates, so that the lower end of the first clamping block 13 can approach the second support arm 113 to contact the material tray 200. When the roller 124 moves along the reverse direction of the third direction with the push rod 123, the first clamping block 13 is reset under the elastic force of the reset member, so that the lower end of the first clamping block 13 can be away from the second support arm 113 to break contact with the material tray 200.

[0068] The reset member may be a coil spring, and the drive unit 122 may be a linear cylinder. In addition, the structural arrangement of the second clamping drive member is the same as that of the first clamping drive member 121 .

[0069] like Figure 2As shown, in one embodiment, the carrier 100 further includes a second driving module 5 and a stop block 6, wherein the second driving module 5 is connected to the first driving module 2 and is used to drive the stop block 6 to move along a first direction; wherein the first direction includes a positive direction and a negative direction, which are opposite to each other, for example, the positive direction of the first direction may be a direction from bottom to top, and the negative direction of the first direction may be a direction from top to bottom. When the stop block 6 moves in the positive direction of the first direction, it can contact with the bearing module 1 so as to drive the bearing module 1 to move in the positive direction of the first direction; when the stop block 6 moves in the positive direction of the first direction, the bearing module 1 can be reset under the action of its own gravity, and the stop block 6 can be separated from the bearing module 1 and spaced apart in the first direction.

[0070] After the retaining block 6 is separated from the carrying module 1 , neither the second driving module 5 nor the retaining block 6 will interfere with the movement of the carrying module 1 relative to the first driving module 2 along the first direction.

[0071] In addition, the stopper 6 may be located below the bearing module 1, and specifically, the stopper 6 may be located below the second bearing plate 223. The second driving module 5 may be installed on the surface of the second bearing plate 223 away from the bearing module, and the second driving module 5 may be a linear cylinder or the like capable of driving an object to move linearly in a device.

[0072] When the second driving module 5 drives the blocking block 6 to move upward, the blocking block 6 can contact the bearing module 1 and drive the bearing module 1 to move upward; when the second driving module 5 drives the blocking block 6 to move downward, the bearing module 1 can be reset under the action of its own gravity. Of course, in other embodiments, when the two ends of the elastic member are respectively connected to the first support block 31 and the second support block 32,

[0073] During operation, the second driving module 5 can first drive the supporting module 1 to move to a predetermined position along the positive direction of the first direction (upward) through the second driving module 5, and then drive the supporting module 1 (and the second driving module 5) to move along the second direction and / or the third direction (i.e. horizontally) to above the material tray 200 through the first driving module 2; then, the second driving module 5 drives the stop block 6 to move downward, so that the supporting module 1 also moves downward to approach the material tray 200; then, the first clamping block 13 and the second clamping block are driven to approach each other to clamp the material tray 200; then, the second driving module 5 drives the supporting module 1 to move upward to drive the material tray 200 to move upward; then, the first driving module 2 drives the supporting module 1 and the material tray 200 to move horizontally for a certain distance; then, the second driving module 5 drives the stop block 6 to move downward, so that the supporting module 1 and the material tray 200 also move downward until the stop block 6 is separated from the supporting module 1 and spaced apart; then, the detection module is used to perform a pressing detection on the circuit board to be tested on the material tray 200.

[0074] like Figure 2 As shown, in one embodiment, the supporting module 1 also includes a plurality of first limiting structures 14. When the supporting module approaches the material tray 200 along the first direction, the plurality of first limiting structures 14 can respectively cooperate with the plurality of second limiting structures on the material tray 200 to limit the relative position of the supporting module 1 and the material tray 200; the plurality of first limiting structures 14 are respectively arranged on the first support arm 112 and the second support arm 113.

[0075] The first limiting structure 14 may be a limiting column, and the second limiting structure may be a limiting hole. Of course, in other embodiments, the first limiting structure 14 may be a limiting hole, and the second limiting structure may be a limiting column.

[0076] It should be understood that the above-mentioned related designs may also be replaced by other methods, such as:

[0077] In other embodiments, the second driving module 22 may drive the first carrying module and the carrying module 1 to move synchronously along the second direction, and the first driving module 21 may drive the carrying module 1 to move along the second direction.

[0078] In other embodiments, the two clamping blocks may be driven in other ways to make the two clamping blocks approach or move away from each other. Specifically, the first clamping drive 121 is used to drive the first clamping block 13 to reciprocate linearly along the second direction to approach or move away from the second clamping block; the second clamping drive is used to drive the second clamping block to reciprocate linearly along the second direction to approach or move away from the first clamping block 13. Among them, the first clamping drive 121 and the second clamping drive can both be linear cylinders. When the first clamping block 13 and the second clamping block are close to each other, the two can clamp and fix the material tray; when the first clamping block 13 and the second clamping block are far away from each other, the two can release the material tray.

[0079] In other embodiments, the multiple first limiting structures 14 may be disposed at positions such that: the multiple first limiting structures 14 are all disposed on the first support arm 112 ; or the multiple first limiting structures 14 are all disposed on the second support arm 113 .

[0080] The present invention also provides a detection device, which includes the carrier 100 described in any one of the above embodiments. In addition, the detection device also includes a detection module, which is used to perform a press-fit test on the circuit board to be tested in the tray 200 placed on the carrier 100. The detection module can be an existing design.

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
