[0031] The utility model provides a positioning mechanism.

[0032] See also Figure 1 In one embodiment of the utility model, the positioning mechanism includes:

[0033] The first mounting frame 100 .

[0034] The positioning assembly 200 comprises:

[0035] The carrier 210 is fixed to the first mounting frame 100 for placing materials, wherein the carrier 210 is fixed to the first mounting frame 100 by screw locking. In this way, the carrier 210 in the present application can be replaced according to different materials. When the carrier 210 needs to be replaced, the carrier 210 can be easily removed from the first mounting frame 100 by screw locking.

[0036] A plurality of clamps 220 movably mounted on the first mounting frame 100 and arranged around the carrier 210; and

[0037] The driving disk 230 is rotatably mounted on the first mounting frame 100 and is drivingly connected to the plurality of the clamps 220, and can drive the plurality of the clamps 220 to synchronously gather toward the center of the carrier 210 to the first preset position, or synchronously move away from the center of the carrier 210 to the second preset position; when the plurality of the clamps 220 synchronously gather toward the center of the carrier 210 to the first preset position, the plurality of the clamps 220 can adjust the position of the material. In this embodiment, the material is transported to the carrier 210 by the first mechanism through the transport mechanism, and at this time, the clamps 220 are in the second preset position. Specifically, when the plurality of clamps 220 are in the second preset position, the mask surrounded by the plurality of clamps 220 is larger than the area of ​​the material, and at this time the transport mechanism can place the material on the carrier 210, and the material is not affected by the clamps 220. After the material is placed on the carrier 210, the drive disk 230 drives the multiple clamps 220 to gather toward the center of the carrier 210 at the same time and move to the first preset position, wherein when the multiple clamps 220 move to the first preset position, the area surrounded by the multiple clamps 220 is the same as the area of ​​the material. In this way, it is possible to avoid excessive clamping of the material by the multiple clamps 220, resulting in damage to the material. At this time, the clamps 220 and the space formed by the multiple clamps 220 are the adjustment space. Since the mask surrounded by the multiple clamps 220 is the same as the mask of the material, the clamps 220 can drive the material to move on the carrier 210 when they gather toward the center of the carrier 210, thereby achieving the purpose of adjusting the position of the material. At the same time, the driving disk 230 in the present application can simultaneously drive multiple clamps 220 to converge toward the center of the carrier 210, or to move away from the center position of the carrier 210. In this way, when positioning the material in the present application, multiple clamps 220 can work synchronously, thereby improving the efficiency of positioning the material. Compared with the step-by-step positioning in the prior art, the efficiency is higher, and the technical problems existing in the prior art can be solved.

[0038] Furthermore, in this embodiment, as to how to make multiple clamps 220 move synchronously to the first preset position or the second preset position, an angle sensor (not shown) can be used to measure the rotation angle of the driving disk 230 through the angle sensor, thereby calculating the synchronous movement of multiple clamps 220 to the first preset position or the second preset position.

[0039] Further, in this embodiment, there are multiple ways for the drive disk 230 to rotate, wherein the drive disk 230 can be directly driven to rotate by the drive motor 240, or the drive disk 230 can be indirectly driven to rotate by the drive motor 240. When the drive motor 240 directly drives the drive disk 230 to rotate, the drive disk 230 is directly connected to the output end of the drive motor 240, so that the drive motor 240 directly drives the drive disk 230 to rotate. When the drive motor 240 indirectly drives the drive disk 230 to rotate, refer to Figure 1 , the driving motor 240 can indirectly drive the driving disk 230 to rotate through the reducer 250. At the same time, when the driving motor 240 indirectly drives the driving disk 230 to rotate through the reducer 250, under the action of the reducer 250, it can achieve a purpose of reducing speed and increasing torque, so that the driving disk 230 can drive multiple clamps 220 to rotate synchronously.

[0040] In one embodiment, the first mounting frame 100 includes a first mounting plate 110, a second mounting plate 120, and a third mounting plate 130 stacked from bottom to top. Specifically, the second mounting plate 120 is fixedly mounted on the first mounting plate 110 at intervals, and the third mounting plate 130 is fixedly mounted on the second mounting plate 120 at intervals. In this embodiment, the first mounting frame 100 is in a retracted state from bottom to top, wherein the carrier 210 is fixedly mounted on the third mounting plate 130 by screw locking, and the plurality of clamps 220 are all movably mounted on the second mounting plate 120.

[0041] In one embodiment, reference Figure 1 The positioning assembly 200 also includes multiple linkage members 260, all of which are installed on the first mounting frame 100. The driving disk 230 is drivingly connected to the multiple linkage members 260. A clamp 220 is fixedly provided on one of the linkage members 260, wherein the driving disk 230 can synchronously drive the multiple clamps 220 by synchronously driving the multiple linkage members 260, so that the multiple clamps 220 gather toward the center of the carrier 210 and to the first position, or so that the multiple clamps 220 are away from the center position of the carrier 210.

[0042] In one embodiment, reference Figure 1, the linkage member 260 may adopt the following structure, the linkage member 260 includes a guide rail 261 and a slider 262, the guide rail 261 is fixed to the first mounting frame 100, the slider 262 is slidably arranged on the guide rail 261, the clamp 220 is fixed to the slider 262, and the drive disk 230 is drivingly connected to the slider 262. In this embodiment, when the first mounting frame 100 includes the first mounting plate 110, the second mounting plate 120 and the third mounting plate 130, the guide rail 261 is fixed to the second mounting plate 120, and specifically, the guide rail 261 is fixed to the second mounting plate 120 by screw locking. In this embodiment, the drive disk 230 is drivingly connected to the slider 262, and the slider 262 can reciprocate along the guide rail 261 by rotating the drive disk 230, so that the clamp 220 fixed on the slider 262 moves toward the center of the carrier 210 or away from the center of the carrier 210. In the present embodiment, the guide rail 261 can be a linear guide rail 261 or a curved guide rail 261. Similarly, the guide rail 261 can also be provided in a slot structure of the second mounting plate 120. When the guide rail is configured as a slot structure (not shown), the slider 262 is slidably disposed in the slot structure. Further, in the present embodiment, when the linkage 260 includes a guide rail and a slider 262, the positioning mechanism also includes a position detection sensor 270. When the clamp 220 follows the slider 262 to move to the first preset position or the second preset position, the position detection sensor 270 obtains information, and then feeds the information back to the drive motor 240 that controls the rotation of the drive disk 230. At this time, the drive motor 240 stops working, that is, the drive disk 230 stops driving. Specifically, the position detection sensor 270 in the present embodiment can be a laser detection sensor 270.

[0043] In one embodiment, reference Figure 1The linkage 260 further includes a driving rod 263, which is rotatably connected to the slider 262 and the driving disk 230. Specifically, one end of the driving rod 263 is connected to the slider 262, and the other end is connected to the driving disk 230. The connection between the driving rod 263 and the driving disk 230 is set away from the rotation axis of the driving disk 230. In this way, when the driving disk 230 rotates, the connection between the driving rod 263 and the driving disk 230 can rotate around the rotation axis of the driving disk 230, so that the driving rod 263 as a whole moves. Since the driving rod 263 is also connected to the slider 262, when the driving rod 263 as a whole moves, it can drive the slider 262 to move along the guide rail 261. In this embodiment, when the driving disk 230 rotates, the driving rod 263 can transmit power to the slider 262, and the slider 262 can move along the guide rail 261, thereby realizing that the clamp 220 moves toward the center of the carrier 210 or away from the center of the carrier 210. That is, the driving rod 263 is connected to the driving disk 230, and when the driving motor 240 drives the driving disk 230 to rotate, the driving disk 230 drives the driving rod 263 to move, and then the driving rod 263 drives the clamp 220 to achieve the material positioning and clamping function. In addition, there are guide rails 261 and sliders 262 under the clamp 220, which can better control the movement of the clamp 220 to achieve the clamping function.

[0044] However, the present design is not limited thereto. In other embodiments, the linkage member 260 may also adopt the following structure, wherein the linkage member 260 includes a guide rail 261, a slider 262, and a spring (not shown), wherein the driving disk is configured as a special-shaped disk (not shown) with a convex portion provided on the outer periphery. At this time, the clamp 220 is fixedly arranged on the slider 262, the slider 262 is slidably arranged on the guide rail 261, the spring is arranged at one end of the slider 262, and the other end of the slider 262 abuts against the outer periphery of the driving disk and slides with it. When the driving disk rotates until the convex portion abuts against the slider 262, at this time, under the action of the convex portion, the slider 262 can move along the guide rail 261 and squeeze the spring to move the clamp 220 away from the center of the carrier 210. Further, the driving disk continues to rotate so that the convex portion does not cooperate with the slider 262. At this time, the slider 262 slides along the guide rail 261 under the action of the spring and abuts against the non-convex portion of the outer portion of the driving disk to move the clamp 220 toward the center of the carrier 210.

[0045] In one embodiment, reference Figure 1The positioning assembly 200 further includes a monitoring sensor 280, which is mounted on the first mounting frame 100 to monitor the material. In this embodiment, the detection sensor 270 is configured as a laser sensor. When the material is placed on the carrier 210, the laser sensor obtains information, thereby controlling the drive disk 230 to drive the multiple clamps 220 to move synchronously, thereby adjusting the position of the material. Specifically, two monitoring sensors 280 are configured. When the drive disk 230 drives the multiple clamps 220 to move synchronously, the laser sensor performs multiple consecutive detections. If no information about the movement of the material is detected, it can be known that the positioning assembly 200 is blocked. At this time, the monitoring sensor 280 feeds back the information to the console, and the console notifies the staff to handle it.

[0046] In one embodiment, reference Figures 1 to 3 , the positioning components 200 are arranged in two groups, both of which are mounted on the first mounting frame 100, and the carriers 210 in the two positioning components 200 are arranged symmetrically. In this embodiment, by setting two groups of positioning components 200, the positioning mechanism of the present application can position two materials, thereby improving the positioning efficiency of the positioning mechanism, but this embodiment is not limited thereto, and in other embodiments, the number of positioning components 200 can also be three or four.

[0047] In one embodiment, reference Figures 1 to 3 , the clamp 220 includes a second mounting frame 221 and an adjusting wheel 222 connected to each other, the driving disk 230 is drivingly connected to the second mounting frame 221, and the adjusting wheel 222 cooperates with the material, wherein when the positioning structure includes a linkage member 260, and the linkage member 260 includes a guide rail 261 and a slider 262, the second mounting frame 221 is fixed to the slider 262, and the second mounting frame 221 follows the slider 262 to slide along the guide rail 261, thereby realizing a driving connection mode between the driving disk 230 and the second mounting frame 221. In other embodiments, the second mounting frame 221 and the driving disk 230 can also adopt other driving connection modes. At the same time, in this embodiment, when the clamp 220 is against the material on the carrier 210 and gathers toward the center position of the carrier 210, the adjusting wheel 222 on the second mounting frame 221 is against the material, and as the second mounting frame 221 gathers toward the center position of the carrier 210, the material is pushed to move, so as to achieve the purpose of adjusting the position of the material.

[0048] In one embodiment, reference Figures 1 to 3The second mounting frame 221 of the clamp 220 located between the two carriers is provided with an avoidance portion 223, the adjusting wheel 222 is mounted on the avoidance portion 223, and the two avoidance portions 223 are staggered with each other; when the clamps 220 in the two positioning assemblies 200 are away from the center of their respective carriers 210 at the same time, the avoidance portions in the two adjacent carriers 210 can avoid each other. At this time, when the two adjacent clamps 220 are away from the center of the corresponding carrier 210 at the same time, the travels of the two clamps 220 can be partially overlapped, that is, the avoidance portions overlap, so that the two adjacent clamps 220 can share a part of the area, so that the structure in the two positioning assemblies 200 can be more compact.

[0049] Further, in this embodiment, reference Figures 1 to 3 , one of the clamps 220 located between the two carriers is arranged in the multiple clamps 220 in the other positioning assembly 200, so that the distance between the two positioning assemblies 200 on the mounting frame can be compact while ensuring the moving distance of the two adjacent clamps 220, so that when the multiple clamps 220 in one positioning assembly 200 are located at the second preset position, the area enclosed by them is as large as possible. Specifically, when the two adjacent clamps 220 are away from the center of the corresponding carrier 210 at the same time, the two adjacent clamps 220 tend to move away from each other. At this time, the two adjacent clamps 220 will not interfere with each other, so that when the multiple clamps 220 in one positioning assembly 200 are located at the second preset position, the area enclosed by them is as large as possible.

[0050] In one embodiment, the drive disks 230 in the two positioning assemblies 200 are connected in parallel to the circuit. Thus, when the positioning mechanism of the present application is in use, if it is found that one of the positioning assemblies 200 needs to be repaired and stopped, the circuit of the drive assembly that needs to be stopped can be cut off, so that the circuit of the other positioning assembly 200 that can work normally is not affected, so that the positioning assembly 200 can continue to work. Similarly, when the positioning assemblies 200 are configured as three or four, when some of the positioning assemblies 200 need to be repaired, the other positioning assemblies 200 that do not need to be repaired can work normally.

[0051] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
