[0031] 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.

[0032] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0033] It should be noted that the first direction described in this application is Figure 1 The Z direction in the present application is Figure 1 In the X direction.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a supporting mechanism for supporting a circuit board (not shown in the figure), and the supporting mechanism includes a driving assembly 1, a supporting frame 2, a supporting assembly 3 installed on the supporting frame 2, and a supporting plate 4 provided with a guide groove 41.

[0035] The support frame 2 is provided with a guide member 21, which is slidably inserted in the guide groove 41 to move the support frame 2 to the support plate 4. The driving assembly 1 is connected to the support frame 2, and is used to drive the support frame 2 to move, so as to drive the guide member 21 to slide in the guide groove 41 so that the support frame 2 and the supporting assembly 3 move along a preset track, so that the supporting assembly 3 can support or release one end of the circuit board, and can avoid the circuit board during the movement. In practical applications, the shape of the guide groove 41 can be designed according to actual needs to achieve that the supporting assembly 3 completely avoids the circuit board during the movement, thereby ensuring that the supporting assembly 3 does not cause damage to the circuit board. It can be understood that the guide member 21 can be a column, a roller, etc. arranged on the support frame 2. In this embodiment, the driving assembly 1 and the supporting assembly 33 are respectively connected to the opposite ends of the support frame 2. In a feasible embodiment, the driving assembly 1 and the supporting assembly 33 can be connected to the same side of the support frame 2, as long as the driving assembly 1 can drive the support frame to move to drive the supporting assembly to move.

[0036] In the utility model, a guide groove 41 is provided on the support plate 4, and a guide member 21 is provided on the support frame 2. The guide member 21 is slidably inserted in the guide groove 41 to move the support frame 2 to the support plate 4. The driving component 1 is connected to the support frame 2 and is used to drive the support frame 2 to move. During the movement of the support frame 2, the guide member 21 slides in the guide groove 41, and the guide groove 41 will limit the moving direction of the support frame 2, so that the supporting component 3 installed on the support frame 2 can move along the preset track defined by the guide groove 41, so that the supporting component 3 can support the bottom of the circuit board, or release the circuit board, with a simple structure, low manufacturing cost, and small space occupation. At the same time, by designing the moving track of the supporting component 3, it is possible to avoid the circuit board when the supporting component 3 moves, thereby preventing the supporting component 3 from causing damage to the circuit board and improving the product yield.

[0037] In one embodiment, if Figure 1 and Figure 2 As shown, the guide groove 41 includes a first groove section 411 and a second groove section 412 that are connected to each other. The driving assembly 1 and the supporting assembly 33 are respectively connected to opposite ends of the support frame 2. The first groove section 411 is located at one end of the second groove section 412 close to the driving assembly 1.

[0038] The supporting mechanism has a first direction, which is the height direction of the supporting mechanism. In the first direction, one end of the first slot section 411 away from the second slot section 412 extends upward, and one end of the second slot section 412 away from the first slot section 411 extends upward, and the guide member 21 can move freely between the first slot section 411 and the second slot section 412. It can be understood that the guide member 21 is slidably inserted in the first slot section 411 and the second slot section 412, and the connecting portion of the first slot section 411 and the second slot section 412 is the lowest point of the guide groove in the first direction.

[0039] Specifically, in the process of the guide member 21 moving from the first groove section 411 to the second groove section 412, the support frame 2 and the supporting assembly 3 thereon first move diagonally downward and then move diagonally upward. In the process of the supporting assembly 3 moving diagonally downward limited by the first groove section 411, the supporting assembly 3 can avoid the bottom of the circuit board to prevent the supporting assembly 3 from scratching the circuit board. In the process of the supporting assembly 3 moving diagonally upward limited by the second groove section 412, the supporting assembly 3 releases the circuit board and provides space for the circuit board to move forward.

[0040] Optionally, the first slot section 411 and the second slot section 412 are one or a combination of a straight slot and an arc slot. It is understandable that the first slot section 411 can be a straight slot or an arc slot, or a combination of a straight slot and an arc slot. Similarly, the second slot section 412 can be a straight slot or an arc slot, or a combination of a straight slot and an arc slot. In this embodiment, the first slot section 411 is an arc slot. More specifically, the first slot section 411 is an arc slot protruding downward in the first direction, so that the supporting component 3 can move away from the bottom of the circuit board more quickly when moving along the first slot section 411, ensuring that the supporting component 3 will not scratch the circuit board. The second slot section 412 is a straight slot, and the supporting component 3 moves along the second slot section 412 to quickly reach the release position, thereby providing space for the circuit board to move forward.

[0041] In one embodiment, if Figure 1 and Figure 2 As shown, the guide groove 41 further includes a third groove section 413, which is disposed at one end of the first groove section 411 away from the second groove section 412 and communicates with the first groove section 411. It can be understood that the third groove section 413 communicates with the second groove section 412 through the first groove section 411.

[0042] The third slot section 413 extends in the horizontal direction, and when the supporting assembly 3 supports the circuit board, the guide member 21 moves into the third slot section 413, and the third slot section 413 is used to support the guide member 21. It can be understood that when the guide member 21 is located in the third slot section 413, the supporting assembly 3 supports the circuit board, and since the third slot section 413 extends in the horizontal direction, the guide member 21 can be well supported, thereby enhancing the stability of the supporting assembly 3 when supporting the circuit board.

[0043] In one embodiment, if Figure 1 and Figure 2 As shown, the guide groove 41 further includes a fourth groove section 414, which is located between the first groove section 411 and the second groove section 412 and communicates with each other. It can be understood that the first groove section 411 communicates with the second groove section 412 through the fourth groove section 414.

[0044] The supporting assembly 3 includes a bearing plate 31 and a connecting plate 32. One end of the connecting plate 32 is connected to the support frame 2, and the other end is connected to the bearing plate 31. The bearing plate 31 is used to support the circuit board. Preferably, the connecting plate 32 is perpendicular to the bearing plate 31, has a hook-shaped structure, and is an integral part to improve the structural strength and ensure that the bearing capacity of the supporting assembly 3 meets the requirements.

[0045] The supporting mechanism also has a second direction, which is the length direction of the supporting mechanism. In the second direction, the sum of the length of the first slot section 411 and the length of the fourth slot section 414 is greater than or equal to the length of the supporting plate 31. Among them, the first direction is perpendicular to the second direction. It can be understood that in the process of the guide member 21 moving from the first slot section 411 through the fourth slot section 414 to the second slot section 412, the supporting assembly 3 first moves obliquely downward, then moves a distance along the second direction, and then moves obliquely upward. Since the sum of the length of the first slot section 411 and the length of the fourth slot section 414 is greater than or equal to the length of the supporting plate 31, the distance moved by the supporting assembly 3 along the second direction is greater than the length of the supporting plate 31 along the second direction during the movement of the supporting assembly 3 toward the oblique downward direction and a distance along the second direction, thereby ensuring that the supporting assembly 3 can completely avoid the circuit board to avoid scratches. Specifically, the length of the first slot segment 411 refers to the distance between the two opposite ends of the first slot segment 411 and the tangent points in the first direction in the second direction. Similarly, the length of the fourth slot segment 414 refers to the distance between the two opposite ends of the fourth slot segment 414 and the tangent points in the first direction in the second direction. Both can be obtained by taking multiple measurements with a measuring tool (such as a vernier caliper) and taking the maximum value.

[0046] In the present invention, when the guide member 21 moves to the third slot section 413 through the second slot section 412, the fourth slot section 414, and the first slot section 411 in sequence, the preset trajectory, i.e., the moving trajectory of the supporting assembly 3, is: firstly moves obliquely downward (limited by the first slot section 411), then moves horizontally (limited by the fourth slot section 414), then moves obliquely upward (limited by the second slot section 412), and finally is limited to the third slot section 413. On the contrary, when the guide member 21 moves to the second slot section 412 through the third slot section 413, the first slot section 411, and the fourth slot section 414 in sequence, the preset trajectory, i.e., the moving trajectory of the supporting assembly 3, is: firstly moves horizontally (limited by the third slot section 413), then moves obliquely downward (limited by the first slot section 411), then moves horizontally (limited by the fourth slot section 414), and finally moves obliquely upward (limited by the second slot section 412). The supporting assembly 3 moves along the preset track designed in this embodiment, which can drive the supporting assembly 3 to support or release the circuit board, and can also avoid the circuit board when the supporting assembly 3 moves, so as to avoid damage to the circuit board caused by the supporting assembly 3. Furthermore, each groove segment has a smooth transition, for example, by connecting with rounded corners, so as to improve the smoothness of the movement of the guide member 21, thereby ensuring the stability of the supporting assembly 3 when moving.

[0047] In one embodiment, if Figure 1 As shown, the driving assembly 1 includes a mobile driving member 11 and a connecting block 12 installed at the output end of the mobile driving member 11, and a limiting hole 121 is provided on the connecting block 12. The extending direction of the limiting hole 121 intersects with the driving direction of the mobile driving member 11. It can be understood that the mobile driving member 11 includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic cylinder, etc. The mobile driving member 11 can drive the connecting block 12 to move in the horizontal direction, that is, to move in the second direction, and the limiting hole 121 extends in the vertical direction, that is, to move in the first direction.

[0048] The driving assembly 1 further includes a connecting member 13 that is movably connected to the limiting hole 121, the support frame 2 is connected to the connecting member 13, the mobile driving member 11 drives the connecting block 12 to move, and while the supporting frame 2 is driven to move by the connecting member 13, the connecting member 13 moves in the limiting hole 121. It can be understood that the connecting member 13 includes a column, a roller, etc.

[0049] Specifically, the limiting hole 121 extends in the vertical direction to provide a degree of freedom in the vertical direction, the mobile driving member 11 drives the support frame 2 to move through the connecting block 12, and during the movement of the guide member 21 in the guide groove 41, the connecting member 13 moves upward or downward in the limiting hole 121, so that the support frame 2 and the supporting assembly 3 thereon can move obliquely upward or obliquely downward. In this embodiment, the supporting mechanism has a simple structure, low manufacturing cost, and small space occupation.

[0050] In one embodiment, if Figure 1 As shown, the supporting mechanism may further include a first roller 5 sleeved on the connecting member 13, and the first roller 5 is rollingly connected to the inner wall of the limiting hole 121. Specifically, when the connecting member 13 moves in the limiting hole 121, the first roller 5 rolls in the limiting hole 121. In this embodiment, the design of the first roller 5 enables rolling friction between the connecting member 13 and the limiting hole 121, thereby reducing the friction between the connecting member 13 and the limiting hole 121, reducing wear, and extending the service life.

[0051] In one embodiment, if Figure 1 As shown, the support mechanism may further include a second roller 6 sleeved on the guide member 21, and the second roller 6 is rollingly connected to the inner wall of the guide groove 41. Specifically, when the guide member 21 moves in the guide groove 41, the second roller 6 rolls in the guide groove 41. In this embodiment, the design of the second roller 6 enables rolling friction between the guide member 21 and the guide groove 41, thereby reducing the friction between the guide member 21 and the guide groove 41, reducing wear, and extending the service life.

[0053] In one embodiment, the supporting mechanism includes at least two support plates 4, and at least two support plates 4 are connected to opposite ends of the support frame 2 to improve the stability of the support frame 2 when it moves. At least one guide groove 41 is provided on one support plate 4. It can be understood that one support plate 4 can be provided with only one guide groove 41, or one support plate 4 can be provided with multiple guide grooves 41, and the multiple guide grooves 41 are arranged at intervals along the second direction and are in the same horizontal plane to avoid interference with the movement of the support frame 2.
