Description

Technical Field

[0001] The utility model belongs to the technical field of material transportation equipment, and in particular relates to a material vehicle positioning device. Background Art

[0002] The loading trolley is one of the most common automated equipment in industrial production. Its main components include a stable body and a well-designed tray. The body is usually made of durable metal and has the ability to carry heavy objects and cope with various challenges in industrial production environments. The tray is located above or in front of the body and is designed to ensure that the workpiece remains stable and accurately positioned during transportation.

[0003] When using a loading cart, workers first place the workpiece to be processed on the tray and use the positioning devices on the tray to ensure that the workpiece is in the correct position and angle. These positioning devices may include clamps, blocks or grooves, which can prevent the workpiece from moving or tilting during transportation.

[0004] This type of material cart is cumbersome to operate and needs to be manually pushed to the designated position each time. It not only consumes a lot of time and manpower, but also the labor cost increases significantly when faced with large-scale production, becoming one of the important factors restricting the improvement of production efficiency. Utility Model Content

[0005] In view of this, the present invention provides a trolley positioning device, which can accurately position the upper and lower trolleys to facilitate subsequent accurate operation of the workpiece.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a material cart positioning device, which includes an upper and lower material cart and a positioning device, the upper and lower material cart is a rectangular shell, the positioning device is C-shaped, the internal size of the positioning device is adapted to the size of the upper and lower material cart, the positioning device is provided with a positioning mechanism for fixing the upper and lower material cart, the positioning mechanism includes a proximity switch, a cylinder and a fixing mechanism, the proximity switch is located in the middle of the interior of the positioning device, the cylinder is located on one side of the top of the positioning device, and is fixedly connected to the positioning device, the fixing mechanism is located at the inner bottom on the other side of the positioning device, and is fixedly connected to the positioning device, and is used to fix the upper and lower material cart.

[0008] On the basis of the above technical solution, a material cart positioning device of the utility model can also be improved as follows:

[0009] Among them, the fixing mechanism includes a spring, a pressure plate and a clamping plate, one end of the spring is fixedly connected to the positioning device, and the other end is fixedly connected to one side of the pressure plate, the pressure plate is a rectangular flat plate, and the two opposite edges of the pressure plate are slidably connected to the two clamping plates. There are two clamping plates, which are located on both sides of the spring and the pressure plate and are rotatably connected to the positioning device; correspondingly, the bottom of the loading and unloading trolley is a rectangular flat plate adapted to the width of the pressure plate.

[0010] Furthermore, the distance between one end of the two clamping plates close to the positioning device is smaller than the width of the pressing plate.

[0011] Furthermore, the fixing mechanism is two magnets, one of which is fixedly connected to the positioning device, and the other is fixed to the bottom of the loading and unloading vehicle.

[0012] Furthermore, the magnet fixed on the positioning device is fixedly connected to the positioning device via a spring.

[0013] The beneficial effect of adopting the above-mentioned improvement scheme is: by providing a spring, the loading and unloading carriage is prevented from being impacted and damaging the workpiece on the top of the loading and unloading carriage when the loading and unloading carriage contacts the positioning device.

[0014] Furthermore, the fixing mechanism is a protrusion fixed to the inner bottom of the positioning device, and the bottom of the loading and unloading vehicle is provided with a depression adapted to the protrusion.

[0015] Furthermore, the thickness in the middle of both sides of the protrusion is greater than the thickness of the end of the protrusion that contacts the positioning device.

[0016] Furthermore, a wedge-shaped block is provided at the air outlet of the cylinder, and a notch corresponding to the wedge-shaped block is provided at a position corresponding to the cylinder on the top of the loading and unloading vehicle.

[0017] The beneficial effect of adopting the above-mentioned improvement scheme is that by setting the wedge block, the loading and unloading trolley obtains a larger impulse when the cylinder impacts and moves toward the fixed mechanism.

[0018] Furthermore, a positioning module for fixing a mechanical gripper is provided on the top of the middle side of the positioning device.

[0019] Furthermore, a sampling table is fixedly installed on one side of the positioning device, and the sampling table is located on the side where the fixing mechanism is installed.

[0020] Compared with the prior art, the beneficial effects of a material cart positioning device provided by the utility model are:

[0021] Precise positioning and fixing: The C-shaped positioning device and the internal positioning mechanism (including proximity switch, cylinder and fixing mechanism) can achieve precise positioning and fixing of the loading and unloading trolley. This ensures that the loading and unloading trolley can maintain a stable position during loading and unloading or other operations, avoiding deviation or shaking, thereby improving production efficiency and work safety.

[0022] Buffer protection: By using a spring or magnet as part of the fixing mechanism, it can effectively provide a buffer when the loading and unloading trolley contacts the positioning device to prevent the loading and unloading trolley from being damaged by impact. At the same time, it also protects the workpieces that may exist on the loading and unloading trolley to prevent them from being damaged by impact.

[0023] Flexible Adaptation: There are many options for the design of the fixing mechanism, such as spring pressure plate clamping plate, magnet, protrusion and depression, etc. These designs can be flexibly adjusted according to different application scenarios and the specific shape of the loading and unloading car to meet different positioning requirements.

[0024] Improve the level of automation: Through the push of the cylinder and the cooperation of the mechanical gripper, the automatic positioning and fixation of the loading and unloading vehicles, as well as the automatic grasping and placement of the workpieces can be achieved, thereby improving the automation level of the entire production line, reducing manual operations and reducing production costs.

[0025] Easy operation: The entire positioning device has a simple structure, is easy to operate, and is easy to maintain and service, which reduces the cost of equipment use.

[0026] To sum up, the material cart positioning device provided by the utility model has the advantages of precise positioning, buffer protection, flexible adaptability, improved automation level and easy operation. It can meet various loading and unloading needs and improve production efficiency and work safety. BRIEF DESCRIPTION OF THE DRAWINGS
