Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0024] As mentioned in the background technology, in the field of mechanical manufacturing, it is necessary to install springs and steel balls on the workpiece and then assemble them with other parts. Taking a rod-shaped product as an example, an assembly hole is opened at the end of the rod-shaped product, and then the spring and steel ball are installed in the assembly hole in sequence by automated equipment. However, before installation, it is necessary to ensure that the position of the assembly hole is facing the installation equipment of the spring or steel ball in order to smoothly realize the assembly. In the prior art, the orientation of the assembly hole is mostly placed manually during the loading process or by using a robot. This not only increases the labor intensity of the workers, but also the manual operation is likely to cause deviations in the position accuracy of the assembly hole, affecting the subsequent assembly of springs and steel balls and reducing production efficiency. Therefore, the positioning mechanism provided in the present application is used to position the installation area 101 on the product 100. Taking a rod-shaped product as an example, the installation area 101 has an assembly hole for assembling springs and steel balls. The positioning mechanism includes a clamping component 1 and a positioning detection component 2. The clamping component 1 includes a first clamping component 11 and a second clamping component 12 that are relatively arranged. The holding component 12, the first clamping component 11 and the second clamping component 12 are movably arranged in a direction relatively close to or away from each other to adapt to products of different lengths. The first clamping component 11 and the second clamping component 12 are respectively rotatably arranged around a predetermined axis, so that after the first clamping component 11 and the second clamping component 12 clamp the product 100, they can drive the product 100 to rotate. The positioning detection component 2 is located above the clamping component 1 and is signal-connected with the first clamping component 11 and the second clamping component 12 respectively. During the rotation of the product 100, when the positioning detection component 2 recognizes the position information of the installation area 101, the signal is fed back to the control center. The control center controls the first clamping component 11 and the second clamping component 12 to stop rotating, so that the installation area 101 is facing the top of the product 100, which is convenient for installing parts in the installation area 101. The mutual cooperation between the clamping component 1 and the positioning detection component 2 is utilized to realize the automatic positioning of the installation area 101, thereby improving the positioning accuracy and production efficiency.

[0025] See also Figure 1 and Figure 2As shown, the present application provides a positioning mechanism for positioning an installation area 101 on a product 100, the positioning mechanism comprising: a clamping assembly 1, the clamping assembly 1 comprising a first clamping part 11 and a second clamping part 12 arranged opposite to each other, the first clamping part 11 and the second clamping part 12 are respectively rotatably arranged around a predetermined axis, and the first clamping part 11 and the second clamping part 12 are movably arranged in a direction of relatively approaching or moving away, the first clamping part 11 and the second clamping part 12 are used to clamp the product 100 and drive the product 100 to rotate; a positioning detection part 2, arranged above the clamping assembly 1, for obtaining a position signal of the installation area 101 during the rotation of the product 100, the positioning detection part 2 is respectively connected to the first clamping part 11 and the second clamping part 12 by signal, so as to control the first clamping part 11 and the second clamping part 12 to stop rotating when the positioning detection part 2 detects the installation area 101.

[0026] The positioning mechanism provided by the present application includes a clamping assembly 1 and a positioning detection component 2. The clamping assembly 1 includes a first clamping component 11 and a second clamping component 12 arranged opposite to each other. The first clamping component 11 and the second clamping component 12 are used to clamp the product 100. The first clamping component 11 and the second clamping component 12 are movably arranged in a direction of being relatively close to or away from each other, so as to ensure the clamping force on the product 100 when the product 100 is transported between the first clamping component 11 and the second clamping component 12, and at the same time, it can also adapt to products of different lengths; in addition, the first clamping component 11 and the second clamping component 12 are arranged around a predetermined axis. It is rotatably arranged to drive the product 100 to rotate. The positioning detection component 2 is located above the clamping component 1 and is used to detect the position information of the installation area 101. During the rotation of the product 100, when the positioning detection component 2 recognizes the installation area 101, the recognition signal is transmitted to the control center. The control center controls the first clamping component 11 and the second clamping component 12 to stop rotating, thereby ensuring that the installation area 101 is positioned above the product 100, thereby facilitating the installation of parts in the installation area 101 during subsequent processing. This not only improves the positioning accuracy of the installation area 101, but also improves the production efficiency of the product 100.

[0027] Preferably, in the present application, the positioning detection component 2 is a laser sensor or an industrial camera. In the actual processing process, there is an assembly hole in the installation area 101. When the positioning detection component 2 is a laser sensor, since the assembly hole is set at the end of the product 100 clamped by the second clamping component 12, at least part of the laser sensor is located above the second clamping component 12 to detect the end of the product 100. By detecting the distance between the laser sensor and the surface of the product 100, when the assembly hole is located below the laser sensor, the distance detected by the laser sensor changes, thereby determining the position of the assembly hole; when the positioning detection component 2 is an industrial camera, by collecting image information on the surface of the product 100, the assembly hole on the surface of the product 100 is identified to achieve assembly hole positioning.

[0028] In the specific implementation process, the clamping assembly 1 further includes: a first driving member 13, the first driving member 13 has a first piston rod, and the first piston rod is telescopically arranged; a first connecting member 14, the two ends of the first connecting member 14 are respectively connected to the first piston rod and the first clamping member 11, and the first piston rod drives the first clamping member 11 to move through the first connecting member 14.

Preferably, the moving track 4 is a linear guide rail, and the first driving member 13 moves along the extension direction of the linear guide rail to drive the first clamping component 11 to move toward or away from the second clamping component 12, so as to adapt to products 100 of different lengths.

Preferably, the second driving member 15 is a second driving cylinder, and the second connecting member 16 is a second connecting plate. The second driving cylinder drives the second clamping member 12 to move through the second connecting plate, so that the second clamping member 12 cooperates with the first clamping member 11 to tighten or release the product 100. Among them, the first driving cylinder is decompressed by a pressure reducing valve, so that the pressure of the first driving cylinder is less than that of the second driving cylinder, so as to ensure that the top force of the second clamping member 12 is greater than that of the first clamping member 11, ensure the consistency of the assembly hole position of the product end, and avoid the instability of the hole position detection.

[0032] Specifically, the end of the product 100 close to the second clamping member 12 is a cone structure, and the clamping assembly 1 also includes a third driving member 17, which has a driving shaft rotatably arranged around its own axis, and the driving shaft is drivingly connected to the second clamping member 12 to drive the second clamping member 12 to rotate; the second clamping member 12 includes: a clamping member 120, the clamping member 120 is connected to the driving shaft, and a second mounting hole is arranged on the clamping member 120, and the hole wall surface of the second mounting hole is a cone surface, and at least part of the product 100 is inserted into the second mounting hole, so that the cone structure of the product 100 fits with the cone surface of the second mounting hole.

[0033] Further, there is a clamping space 10 for accommodating the product 100 between the first clamping member 11 and the second clamping member 12, and the positioning mechanism further includes: a photoelectric sensor 6, which is arranged at the side of the clamping space 10, and the photoelectric sensor 6 is used to detect the position information of the product 100; the photoelectric sensor 6 is connected to the first clamping member 11 and the second clamping member 12 by signals, so that when the photoelectric sensor 6 detects the product position information in the clamping space 10, the first clamping member 11 and the second clamping member 12 are moved to clamp the product 100. Preferably, the photoelectric sensor 6 is connected to the first driving member 13 for driving the first clamping member 11 to move by signals, and at the same time, the photoelectric sensor 6 is connected to the second driving member 15 for driving the second clamping member 12 to move by signals, so that after detecting that the product 100 is located in the clamping space 10, the photoelectric sensor 6 transmits signals to the first driving member 13 and the second driving member 15, respectively, and at this time, the first clamping member 11 and the second clamping member 12 are controlled to move relative to each other to clamp the product 100.

[0034] In the present application, the positioning mechanism also includes: a supporting block 5, at least a portion of which is arranged between the first clamping component 11 and the second clamping component 12, and a supporting groove 50 for supporting the product 100 is arranged on the supporting block 5, and the supporting block 5 is movably arranged in the vertical direction to support or release the product 100; a fourth driving member 7, the fourth driving member 7 includes a third piston rod 70, the third piston rod 70 is telescopically arranged in the vertical direction, and the third piston rod 70 is drivingly connected to the supporting block 5 to drive the supporting block 5 to move.

When the first drive member 13 and the second drive member 15 transmit the action signal of the piston extension to the fourth drive member 7, the fourth drive member 7 drives the supporting block 5 to move downward to disengage from the product 100, thereby avoiding the problem of scratches on the surface of the product 100 due to friction between the surface of the product 100 and the wall of the supporting groove 50 during the rotation of the product 100.

[0035] Preferably, there are at least two supporting blocks 5 , and the at least two supporting blocks 5 are spaced apart along the length direction of the product 100 to support the product 100 together.

[0040] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0041] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
