[0003] Among them, the conveyor belt is a key component of the production line. It is responsible for transporting the semi-finished airbag boxes (hereinafter referred to as "semi-finished products"), and then the semi-finished products are clamped from the conveyor belt by a robotic arm and transported to the next process for processing; currently, there is a lack of a positioning device on the conveyor belt, and the semi-finished products may shift in position due to speed, vibration, or human factors on the conveyor belt, resulting in inaccurate positioning points when the robotic arm clamps the semi-finished products, and the clamping points deviate from the predetermined positions, affecting the smooth progress of subsequent processes. Summary of the Utility Model

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a positioning device on a conveyor belt, which can effectively solve the problems existing in the above-mentioned prior art.

[0005] The technical solution of the utility model is as follows:

[0006] According to one aspect of the utility model, it includes: a conveyor belt and a robotic arm. A number of semi-finished product boxes are distributed on the conveyor belt. A clamping point is set on the conveyor belt. The robotic arm is used to transport the semi-finished product boxes from the clamping point to the next process. It further includes a second push plate, and the second push plate is equipped with a second driving device for pushing the semi-finished product boxes to move towards the clamping point.

[0007] It further includes an induction device, which is used to sense whether the semi-finished product boxes move to the conveying end of the conveyor belt. When the induction device senses the semi-finished product boxes, the conveyor belt stops moving, and the second driving device drives the second push plate to move, prompting the semi-finished product boxes to move to the clamping point.

[0008] Furthermore, it further includes at least two first push plates. The two first push plates are respectively arranged on the left and right sides of the clamping point, and both of the two first push plates are equipped with a first driving device for pushing the semi-finished product boxes to move towards the clamping point.

[0009] Furthermore, the two first push plates are symmetrically arranged on both sides of the conveyor belt.

[0010] Furthermore, each of the two first push plates is provided with an inclined surface, and when the first push plate pushes the semi-finished product box body, the inclined surface abuts against the semi-finished product box body.

[0011] Furthermore, both the first driving device and the second driving device are air cylinders.

[0012] Furthermore, two enclosing plates are further included, the conveyor belt is arranged between the two enclosing plates, the two first driving devices are respectively fixed on the two enclosing plates, and a support member is fixedly arranged between the first driving device and the enclosing plate.

[0013] Furthermore, a limiting device is further included, and the limiting device is used to align one side of a plurality of semi-finished product box bodies, so that when the plurality of semi-finished product box bodies move on the conveyor belt, the left and right ends of two adjacent semi-finished product box bodies are aligned.

[0014] Furthermore, the limiting device includes a limiting rod, the limiting rod is arranged at the upper end of the conveyor belt, a gap is formed between the limiting rod and the conveyor belt, and one end of each of the plurality of semi-finished product box bodies abuts against the limiting rod.

[0015] Adopting the above technical solution, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] First, when the induction device senses the semi-finished product box body, the second push plate pushes the semi-finished product box body towards the clamping position, which can ensure that the semi-finished product box body accurately stays at the clamping position of the robotic arm on the conveyor belt. In this way, the robotic arm can quickly and accurately find the target during clamping, reducing the clamping failure or repeated adjustment time caused by position deviation. Due to accurate positioning, the robotic arm can immediately perform the clamping operation, thereby shortening the production cycle and improving the overall production efficiency.

[0017] Second, the limiting device is used to align one side of a plurality of semi-finished product box bodies, so that when the plurality of semi-finished product box bodies move on the conveyor belt, the left and right ends of two adjacent semi-finished product box bodies are aligned. Through the limiting device, the semi-finished product box bodies on the conveyor belt can maintain a stable arrangement and spacing, which is beneficial to the continuous operation of subsequent processes and reduces the downtime waiting time.
