Description

Technical Field

[0001] This invention relates to the field of automated production lines, and in particular to an automated production line for engine housings. Background Technology

[0002] An automated production line for engine housings is a supporting equipment for the production and processing of engine housings. When producing and processing engine housings, an automated production line needs to be set up for integrated processing. The production line generally includes a feeding mechanism, a conveying mechanism, a gripping mechanism, and a processing mechanism. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of automated production lines for engine housings.

[0003] Existing engine casing production lines have certain drawbacks. First, manual loading and unloading are used in the early stages of processing, reducing work efficiency and resulting in poor automation performance, which is not conducive to user operation. Furthermore, the clamps cannot adequately meet the product stability requirements, leading to poor overall production efficiency. Automated lines also occupy a large area, and processing and inspection are cumbersome, negatively impacting user experience. Therefore, we propose an automated engine casing production line. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated production line for engine casings. The production line features a modular layout with four relatively independent production units. The automated line occupies less floor space. When the production line is running at full speed, the gripper design meets product stability and appearance requirements, optimizes robot gripping actions, and improves overall production efficiency, effectively solving the problems in the background technology.

[0090] 1.2 Loading and unloading unit:

[0091] 1.2.1 Manual feeding can be used, or it can be combined with automated feeding systems such as AGVs;

[0092] 1.2.2 The loading area has three stations: two for raw materials and one for empty pallets. All three stations can be used for either raw materials or empty pallets, allowing for cyclical stacking.

[0093] 1.2.3 The unloading area has three stations: one for empty pallets, one for qualified products, and one for defective products.

[0094] 1.2.4 The blank loading station uses visual recognition to identify the product posture and guides the robot to grasp it. An alarm is triggered when the blank posture in the tray is abnormal.

[0095] 1.2.5 The initial plan is for a 4-hour cycle for the feeding interval;

[0096] 1.2.6 The tolerance for the loading position of the blank pallet must be within ±20mm;

These mechanisms assist the robot in cleaning the product positioning surfaces and transitioning product postures.

[0103] 1.3.2 The air-blowing cleaning unit uses compressed air to clean the product, and the debris is collected for easy regular cleaning;

[0104] 1.3.3 The air blowing unit requires full protection to reduce noise; the air blowing unit is equipped with an air tank, which has a safety valve and a pressure gauge;

[0105] 1.3.4 The flipping unit adopts a pneumatic flipping mechanism, which saves robot operation time;

[0106] 1.3.5 The air blowing and flipping unit is compatible with both upper and lower housing products;

[0107] 1.3.6 This unit is equipped with a funnel for collecting water and debris to prevent wastewater overflow.

[0108] 1.4 Temporary Storage Unit:

[0109] 1.4.1 Transfer is carried out using a double-speed, multi-level circular logistics line with pallets, and the pallets need to be buffered;

[0110] 1.4.2 The number of upper and lower box pallets is configured according to 9 sets each, of which 2 sets of pallets are reserved;

[0111] 1.4.3 A top and bottom recirculation configuration is adopted to achieve tray recirculation;

[0112] 1.4.4 Configure a manual operation position to enable manual loading and unloading operations;

[0113] 1.4.5 Add equipment alarm lights and a local operation button for manual mode to facilitate on-site personnel in checking problems.

[0114] 1.5 Feed and discharge conveyor lines:

[0115] 1.5.2 Logistics line speed: 6 meters / minute;

[0119] 1.5.6 The length of the conveyor belt can accommodate multiple sets of workpieces; the specific length is subject to the final design.

[0120] 1.5.7 For the feeding logistics line, the belt thickness has been increased to take into account the manual feeding methods and habits;

[0121] 1.5.8 If the product posture or position on the feeding line is incorrect, the system will issue an alarm;

[0122] Version 1.5.9 adds an alarm light and a local operation button for manual operation, making it easier for on-site personnel to check for problems.

[0123] 1.6 Cooling Unit

[0124] Before the four-unit leak test, a constant temperature unit is installed after the cleaning machine to keep the workpiece temperature constant, mainly for heat dissipation.

[0125] It has temperature detection function;

[0126] Adding equipment alarm lights and a local operation button for manual mode makes it easier for on-site personnel to check for problems.

[0127] 1.7 All actions of the robot and machine tool shall be performed in sequence. Each action must be confirmed before execution. The next action can only be performed after receiving a feedback signal that the previous action has been completed. Otherwise, no action shall be performed.

[0128] 1.8 Protective measures should be in place in areas where the robot gripper passes to prevent cutting fluid from falling onto the ground and polluting the environment.

[0129] It should be noted that, in this document, relational terms such as first and second (number one, number two), etc., are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
