[0022] In this embodiment, the product clamping area is composed of the bottom plate 1, the X-direction reference block 21, the Y-direction reference block 31, the X-direction push block 22 and the Y-direction push block 32. The product is precisely positioned in both directions by setting the reference blocks in the X and Y directions, and the product is elastically clamped by the elastic push blocks (slidable push blocks + elastic members) respectively opposite to the two reference blocks, and the sliding parts of the two push blocks (X-direction slider 24, Y-direction slider 34) are respectively provided with mutually matching cam tracks 52 and cam followers 51, so that only one-way power is required to achieve precise positioning and clamping of the product in the X and Y directions. The product elastic clamping mechanism of this embodiment adopts the combination of elastic push blocks and cam components, and only one-way force is required to accurately position the product in the X and Y directions, and the elastic buffering effect of the elastic member makes it difficult for the elastic clamping mechanism to cause damage to the product, which is very beneficial to products that cannot be clamped rigidly or vigorously, such as PCB board 6 (i.e. printed circuit board), and plays a good protective role on the product. It has a simple structure, convenient operation, and the size can be increased or decreased according to actual needs, and has a wide range of applications.

[0023] The working principle of the product elastic clamping mechanism of this embodiment is as follows:

[0024] In the absence of external force, the X-direction elastic member 25 and the Y-direction elastic member 36 are in an extended state, and the cam follower 51 is in the concave section 522 of the cam track 52. At this time, the X-direction push block 22 and the Y-direction push block 32 are in a relaxed state, and the distance between the X-direction push block 22 and the X-direction reference block 21 is the smallest, and the distance between the Y-direction push block 32 and the Y-direction reference block 31 is the smallest.

[0025] When it is necessary to clamp the product, the driving assembly 4 applies a thrust to the limit block 35. Under the action of the thrust, the limit block 35 compresses the Y-direction elastic member 36 and pushes the Y-direction slider 34. The Y-direction slider 34 drives the Y-direction push block 32 to move away from the Y-direction reference block 31 to increase the distance between the Y-direction push block 32 and the Y-direction reference block 31. At the same time, the cam follower 51 slides to the outer convex section 521 of the cam track 52, so that the X-direction push block 22 moves away from the X-direction reference block 21, compressing the X-direction elastic member 25 to increase the distance between the X-direction push block 22 and the X-direction reference block 21. That is, at this time, the product elastic clamping mechanism is in an open state, and the product can be placed in the clamping area. Figure 2 As shown. Subsequently, the compressed Y-direction elastic member 36 gradually resumes its extended state, and its elastic force causes the limit block 35 to move away from the bottom plate 1, thereby pulling the Y-direction slider 34, and the Y-direction slider 34 drives the Y-direction push block 32 to move toward the Y-direction reference block 31 until the product is clamped from the Y direction; as the Y-direction slider 34 slides, the cam follower 51 slides along the cam track 52 to the concave section 522, and the compressed X-direction elastic member 25 resumes its extended state to clamp the product from the X direction, as shown. Figure 3 shown.

[0026] When the product needs to be taken away, the control driving assembly 4 applies a thrust to the limit block 35 to put the product elastic clamping mechanism in an open state (the process is the same as above).

[0027] Furthermore, in this embodiment, the convex section 521 is a straight section (convex relative to the concave section 522), the concave section 522 is a first arc segment that bends inward (inside the Y-direction slider 34), and the straight section and the first arc segment are transitioned through a second arc segment. Using a straight section as the convex section 521 and an arc segment as the concave section 522 and the transition section can reduce the resistance of the cam follower 51 sliding from the concave section 522 to the convex section 521, saving driving force. On the contrary, the cam track 52 has a smooth transition, and the cam follower 51 slides from the convex section 521 to the concave section 522 at a slow speed, which can further reduce the impact force of the clamping mechanism on the product, which is beneficial to protecting the product.

[0028] Furthermore, in this embodiment, the X-direction reference block 21, the Y-direction reference block 31, the X-direction push block 22, and the Y-direction push block 32 are all provided with elastic cushion layers such as rubber cushions on the sides in contact with the product. Providing an elastic cushion layer on the contact surface between the clamping mechanism and the product is conducive to reducing the impact force of the clamping mechanism on the product and improving the protection effect on the product.

[0029] Furthermore, in this embodiment, the X-direction elastic member 25 is an X-direction spring, and the Y-direction elastic member 36 is a Y-direction spring. Of course, other elastic members may also be used in other embodiments.

[0030] Furthermore, in this embodiment, the driving component 4 is a cylinder.

[0031] Furthermore, in this embodiment, the middle of the Y-direction sliding block 34 is a hollow structure 341, which is helpful to reduce the weight of the clamping mechanism and save materials.

[0032] Furthermore, in this embodiment, one end of the Y-direction slider 34 is connected to the rear end of the Y-direction push block 32 via a bent transition section 37. Of course, in other embodiments, one end of the Y-direction slider 34 may also be connected to the bottom of the Y-direction push block 32 via a connecting member such as a vertical connecting plate, but a notch for avoiding the connecting member needs to be provided on the top wall of the Y-direction slideway 33.

Any technician familiar with the art can use the above disclosed technical content to make many possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
