[0046] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0047] As Figures 1 to 5As shown in the figure, an adjustment mechanism provided by an embodiment of the present utility model includes a driving component 1, a first sliding member 2, a second sliding member 3, and a connecting member 4. The output end of the driving component 1 is connected to the first sliding member 2. The second sliding member 3 is slidably connected to the first sliding member 2. When the driving component 1 drives the first sliding member 2 to move, the second sliding member 3 will move together with the first sliding member 2. One end of the connecting member 4 is rotatably connected to the second sliding member 3 around a first axis, and the other end of the connecting member 4 is installed on the component to be adjusted. The transmission connection between the second sliding member 3 and the component to be adjusted is realized through the connecting member 4.
[0048] By driving the first sliding member 2 and the second sliding member 3 to reciprocate in a first direction, the driving component 1 can drive the connecting member 4 to rotate around the first axis, so that one end of the connecting member 4 drives the second sliding member 3 to reciprocate relative to the first sliding member 2 in a second direction, and the other end of the connecting member 4 drives the component to be adjusted to rotate around a second axis. Among them, the first direction a and the second direction b are not parallel and not collinear.
[0049] When the first sliding member 2 and the second sliding member 3 move in the first direction, one end of the connecting member 4 moves along the first direction under the drive of the second sliding member 3. Since the other end of the connecting member 4 is installed on the component to be adjusted and the component to be adjusted does not move in the first direction, the movements of the two ends of the connecting member 4 cannot be synchronized, thus generating rotation along the first axis. And during the rotation of the connecting member 4, the connecting member 4 drives the component to be adjusted to rotate around the second axis, and the distance between the component to be adjusted and the first sliding member 2 will change. At this time, the end of the connecting member 4 close to the second sliding member 3 can drive the second sliding member 3 to move relative to the first sliding member 2, so as to compensate for the distance change between the component to be adjusted and the first sliding member 2 caused by the rotation of the connecting member 4. It should be noted that the movement of the second sliding member 3 relative to the first sliding member 2 in the second direction and the rotation of the component to be adjusted around the second axis occur simultaneously.
[0050] In this embodiment, when the first sliding member 2 moves in the first direction and the second sliding member 3 follows the first sliding member 2 to move in the first direction, the second sliding member 3 will also move in the second direction under the drive of the connecting member 4. Through the connecting member 4, the linear movements in two directions can be converted into the rotational movement of the component to be adjusted, realizing the adjustment of the rotation angle of the component to be adjusted. Moreover, the overall structure of the adjustment structure is relatively simple, with few components, and it will not occupy too much space in the PCB testing equipment, and can meet the requirements of high-precision adjustment in a narrow space.
[0051] Preferably, the first direction a and the second direction b are perpendicular, the first axis and the second axis are parallel to each other, and the first axis is perpendicular to both the first direction a and the second direction b.
[0052] In one embodiment, as Figure 1As shown, one end of the connecting member 4 is connected to the second sliding member 3 through a bearing, such that when the second sliding member 3 moves in the first direction, the connecting member 4 will generate a rotational movement about the first axis.
[0053] Wherein, a connecting hole 41 is provided on the connecting member 4, the outer ring of the bearing is connected to the inner wall surface of the connecting hole 41, the inner ring of the bearing is connected to the second sliding member 3, and relative rotation can occur between the inner ring and the outer ring of the bearing, thereby realizing the rotation of the connecting member 4.
[0054] In some alternative embodiments, one end of the connecting member 4 is rotatably connected to the second sliding member 3 through a pin shaft.
[0055] In one embodiment, as Figure 1 shown, the adjustment mechanism further includes an adapter 5, and the adapter 5 is adapted to be connected between the member to be adjusted and the end of the connecting member 4 away from the second sliding member 3, which facilitates the fixation of the connecting member 4 and the member to be adjusted.
[0056] Wherein, the surface of the adapter 5 close to the member to be adjusted is a flat surface or a curved surface, which can adapt to the connection between the member to be adjusted with different shapes and the connecting member 4.
[0057] When the member to be adjusted is square or other polygons, the surface of the adapter 5 close to the member to be adjusted is a flat surface. When the member to be adjusted is cylindrical or annular, the surface of the adapter 5 close to the member to be adjusted is a curved surface.
[0058] In the PCB detection device, the member to be adjusted is a crossed roller bearing 9, the surface of the adapter 5 close to the member to be adjusted is arc-shaped and adheres to the crossed roller bearing 9, and the inner ring or the outer ring of the crossed roller bearing 9 can be driven to rotate through the connecting member 4, thereby realizing the T-axis adjustment of the crossed roller bearing 9.
[0059] In one embodiment, as Figure 1 、 Figure 3 shown, the adjustment mechanism further includes a first slide rail 61 and a first slider 62, the first slider 62 is slidably connected to the first slide rail 61, one of the first slide rail 61 and the first slider 62 is provided on the first sliding member 2, the other is provided on the second sliding member 3, and the first slide rail 61 extends in the second direction. The first slider 62 and the first slide rail 61 can slide relatively, which can guide the movement of the second sliding member 3, thereby realizing the movement of the second sliding member 3 relative to the first sliding member 2 in the second direction.
[0060] Specifically, the first slide rail 61 is installed on the side of the first sliding member 2 close to the second sliding member 3, the first slider 62 is installed on the side of the second sliding member 3 close to the first sliding member 2, and the first slider 62 is slidably connected to the first slide rail 61.
[0061] In one embodiment, asFigure 1 , Figure 3 As shown in Figure 3 , there are two first slide rails 61. Correspondingly, there are two second sliders 64. The two first slide rails 61 are spaced apart on the first sliding member 2. Each first slider 62 is slidably connected to the corresponding first slide rail 61, further ensuring the stability when the second sliding member 3 moves relative to the first sliding member 2.
[0062] In one embodiment, as Figure 1 , Figure 3 shown, the adjustment mechanism further includes a second slide rail 63 and a second slider 64. The second slider 64 is slidably connected to the second slide rail 63. One of the second slide rail 63 and the second slider 64 is provided on the first sliding member 2, and the other is adapted to be provided on the detection mechanism of the PCB detection device. The second slide rail 63 extends along the first direction. The second slider 64 and the second slide rail 63 can slide relative to each other, so that when the first sliding member 2 moves along the first direction, the movement of the first sliding member 2 is guided.
[0063] Specifically, the second slide rail 63 is installed on the detection mechanism of the PCB detection device, and the second slider 64 is installed on the side of the first sliding member 2 away from the second sliding member 3. The second slider 64 is slidably connected to the second slide rail 63.
[0064] In one embodiment, there are two second slide rails 63 and two second sliders 64. The two second slide rails 63 are spaced apart on the first sliding member 2 and are arranged on opposite sides of the first sliding member 2 along the second direction. Each second slider 64 is slidably connected to the corresponding second slide rail 63, further ensuring the stability when the first sliding member 2 moves along the first direction.
[0065] In one embodiment, as Figure 1 , Figure 3 shown, the adjustment mechanism further includes a first limiting member 71 and a second limiting member 72. The first limiting member 71 and the second limiting member 72 can limit the rotation angle of the connecting member 4 when the member to be adjusted rotates around the second axis, thereby limiting the rotation angle of the member to be adjusted.
[0066] Among them, based on the zero position of the first sliding member 2, the adjustable angle range of the member to be adjusted is ±3.5°. This angle range can be set according to actual needs.
[0067] In one embodiment, the first limiting member 71 and the second limiting member 72 are arranged on opposite sides of the connecting member 4 along a first direction. The member to be adjusted can rotate forward and backward about a second axis. The first limiting member 71 is used to stop the connecting member 4 when the member to be adjusted rotates forward, and the second limiting member 72 is used to stop the connecting member 4 when the member to be adjusted rotates backward. The movement range of the connecting member 4 can be limited by the first limiting member 71 and the second limiting member 72, thereby restricting the rotation angle of the member to be adjusted.
[0068] Specifically, when the first sliding member 2 and the second sliding member 3 move upward along the first direction a as Figure 3 shown, the connecting member 4 rotates about the first axis and drives the member to be adjusted to rotate in the clockwise direction until the connecting member 4 abuts against the first limiting member 71 and stops. At this time, the member to be adjusted reaches the maximum angle of rotation in the clockwise direction.
[0069] When the first sliding member 2 and the second sliding member 3 move downward along the first direction as Figure 3 shown, the connecting member 4 rotates about the first axis and drives the member to be adjusted to rotate in the counterclockwise direction until the connecting member 4 abuts against the second limiting member 72 and stops. At this time, the member to be adjusted reaches the maximum angle of rotation in the counterclockwise direction.
[0070] In one embodiment, as Figure 4 、 Figure 5 shown, the first limiting member 71 includes a first mounting seat 711, a first support member 712, and a first buffer pad 713. The first mounting seat 711 is fixed on the detection mechanism of the PCB detection device. The first support member 712 is mounted on the first mounting seat 711. The first buffer pad 713 is mounted at one end of the first support member 712 close to the connecting member 4. The first buffer pad 713 can abut against the connecting member 4, thereby buffering the connecting member 4 and avoiding rigid collision between the connecting member 4 and the first support member 712 when stopping the connecting member 4.
[0071] The second limiting member 72 includes a second mounting seat 721, a second support member 722, and a second buffer pad 723. The second mounting seat 721 is fixed on the detection mechanism of the PCB detection device. The second support member 722 is mounted on the second mounting seat 721. The second buffer pad 723 is mounted at one end of the second support member 722 close to the connecting member 4. The second buffer pad 723 can abut against the connecting member 4, thereby buffering the connecting member 4 and avoiding rigid collision between the connecting member 4 and the second support member 722 when stopping the connecting member 4.
[0072] Wherein, the first buffer pad 713 is a rubber pad or a silica gel pad, and the second buffer pad 723 is a rubber pad or a silica gel pad.
[0073] In one embodiment, as Figure 1 、 Figure 3As shown, the driving assembly 1 includes a driving motor 11, a coupling 12, and a lead screw 13. The coupling 12 is connected between the output end of the driving motor 11 and the lead screw 13. The first sliding member 2 is sleeved on the lead screw 13. The driving motor 11 can drive the lead screw 13 to rotate, and then drive the first sliding member 2 to reciprocate along the first direction through the lead screw 13. By driving the lead screw 13 to rotate through the driving motor 11, the moving distance of the first sliding member 2 can be better controlled, and then the rotation angle of the member to be adjusted can be adjusted more accurately.
[0074] Among them, when the driving motor 11 drives the lead screw 13 to rotate clockwise, the first sliding member 2 and the second sliding member 3 move upward as shown in Figure 3 and drive the member to be adjusted to rotate clockwise through the connecting member 4 until the connecting member 4 abuts against the first limiting member 71. When the driving motor 11 drives the lead screw 13 to rotate counterclockwise, the first sliding member 2 and the second sliding member 3 move downward as shown in Figure 3 and drive the member to be adjusted to rotate counterclockwise through the connecting member 4 until the connecting member 4 abuts against the second limiting member 72.
[0075] In an embodiment, as shown in Figure 1 、 Figure 3 the driving assembly 1 further includes two lead screw support seats 14. The lead screw support seats 14 are fixed on the detection mechanism of the PCB detection device. The lead screw 13 is rotatably supported between the two lead screw support seats 14, and the two lead screw support seats 14 support the lead screw 13. The first sliding member 2 reciprocates between the two lead screw support seats 14. When the connecting member 4 rotates around the first axis, its rotation range is limited between the first limiting member 71 and the second limiting member 72, thereby limiting the moving stroke of the first sliding member 2. The distance between the two lead screw support seats 14 is at least equal to the moving stroke of the first sliding member 2.
[0076] Specifically, the distance between the two lead screw support seats 14 is equal to the moving stroke of the first sliding member 2. When restricting the rotation angle of the connecting member 4 through the first limiting member 71 and the second limiting member 72, it can also prevent the first sliding member 2 from colliding with the lead screw support seat 14 when moving along the first direction. Or the distance between the two lead screw support seats 14 is greater than the moving stroke of the first sliding member 2. The first limiting member 71 and the second limiting member 72 can define the moving range of the first sliding member 2 between the two lead screw support seats 14.
[0077] In an embodiment, as shown in Figure 1 、 Figure 2As shown, the adjustment mechanism further includes a first sensor 81, a second sensor 82, and a third sensor 83. The second sensor 82 is arranged between the first sensor 81 and the third sensor 83 along the first direction. An induction piece 21 is arranged on the first sliding member 2. The first sliding member 2 can drive the induction piece 21 to move along the first direction, and the induction piece 21 can trigger the first sensor 81, the second sensor 82, or the third sensor 83.
[0078] Among them, the induction piece 21 can trigger the first sensor 81 to detect the positive limit position of the first sliding member 2. The induction piece 21 can trigger the second sensor 82 to detect the zero position of the first sliding member 2. The induction piece 21 can trigger the third sensor 83 to detect the negative limit position of the first sliding member 2. The moving range of the first sliding member 2 is limited by the first sensor 81 and the third sensor 83. The zero position of the first sliding member 2 can be determined by the second sensor 82. Based on the zero position, it is convenient to adjust the angle of the part to be adjusted.
[0079] In one embodiment, as Figure 2 shown, the induction piece 21 includes a connecting portion 211, a first induction portion 212, and a second induction portion 213. The connecting portion 211 is installed on the first sliding member 2. The first induction portion 212 and the second induction portion 213 are arranged at intervals on the connecting portion 211. The second sensor 82 can sense the first induction portion 212, and the first sensor 81 and the third sensor 83 can sense the second induction portion 213.
[0080] The first sensor 81 and the third sensor 83 limit the moving range of the first sliding member 2. Since the moving range of the first sliding member 2 is small, the remaining space between the first sensor 81 and the third sensor 83 is not enough to place the second sensor 82. In this embodiment, the first sensor 81 and the third sensor 83 are on the same straight line in the first direction, and the second sensor 82 is misaligned with the first sensor 81 in the first direction. The second sensor 82 is farther away from the first sliding member 2 than the first sensor 81, avoiding the second sensor 82 interfering with the first sensor 81 and the third sensor 83.
[0081] In order to enable all sensors to sense, the first induction portion 212 and the second induction portion 213 are arranged on the induction piece 21. The first induction portion 212 can cooperate with the second sensor 82, and the second induction portion 213 can cooperate with the first sensor 81 and the third sensor 83 to trigger sensors at different positions.
[0082] In one embodiment, as Figure 3As shown, when the first slider 2 is at the zero position, the connecting member 4 extends in the second direction. At this time, the distance between the member to be adjusted and the first slider 2 is the smallest. When the first slider 2 moves along the first direction and leaves the zero position, the extending direction of the connecting member 4 forms an acute angle with respect to the second direction. By setting the position where the extending direction of the connecting member 4 coincides with the second direction as the zero position, it is convenient to determine the rotation direction of the member to be adjusted based on the position of the connecting member 4.
[0083] On the other hand, an embodiment of the present invention provides a PCB detection device, which includes a detection mechanism, a member to be adjusted, and the adjustment mechanism of the above embodiment. The member to be adjusted and the adjustment mechanism are installed on the detection mechanism, and the connecting member 4 is connected between the member to be adjusted and the second slider 3. The driving assembly 1 drives the first slider 2 and the second slider 3 to move along the first direction, which can drive the connecting member 4 to rotate around the first axis, thereby realizing the rotational adjustment of the member to be adjusted.
[0084] Among them, as Figure 1 、 Figure 3 shown, the member to be adjusted is a crossed roller bearing 9. One end of the connecting member 4 away from the second slider 3 is connected to the inner ring or outer ring of the crossed roller bearing 9, and the inner ring or outer ring of the crossed roller bearing 9 rotates around the second axis.
[0085] In a specific embodiment, the outer ring of the crossed roller bearing 9 remains stationary, and one end of the connecting member 4 away from the second slider 3 is connected to the inner ring of the crossed roller bearing 9. Driven by the driving assembly 1, the connecting member 4 can drive the inner ring of the crossed roller bearing 9 to rotate around the second axis.
[0086] In an embodiment, the PCB detection device further includes a loading and unloading mechanism, which has a loading position, an unloading position, and a robotic arm. The robotic arm can transfer the PCB board at the loading position to the detection mechanism. After the detection mechanism finishes detecting the PCB board, the robotic arm transfers the PCB board to the unloading position.
[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
