Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, and specifically relates to a material separating device for preventing lamination. Background Technique

[0002] With the rapid development of the manufacturing industry, pursuing product quality and saving manufacturing costs have become the two most concerned issues for enterprises. Since the parts of our company are high-concern appearance parts with very high appearance protection requirements, before stamping, a protective film needs to be coated on the appearance surface of the material sheet to be stamped. Due to the sealing property of the protective film, the two adjacent material sheets above and below are likely to be adsorbed together. If the employee does not confirm carefully, it will cause double sheets / multiple sheets of materials during stamping, resulting in damage to the forming die due to material jamming and cracking. When the die is damaged, production cannot continue, which will further lead to the risk of economic penalties for customer line stoppage. At the same time, a large amount of die repair costs will be generated due to the need to newly manufacture the master die. Content of the Utility Model

[0003] The utility model provides a material separating device for preventing lamination to solve the technical problems proposed in the background technique.

[0004] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to the appendix. Figure 1 , 2 This embodiment provides a material distribution device for preventing stacking of sheets, including a mounting frame 1. The mounting frame 1 has at least two semi-open hoppers 2, each containing multiple sheets 3 to be tested. A testing platform 4 is located on the left side of the mounting frame 1, with multiple vacuum nozzles 8 on its surface. A thickness sensor 41 is located on one side of the testing platform 4. Support rods 5 are located around the semi-open hoppers 2, and two parallel mounting plates 6 are located at the top of the support rods 5. The length of the mounting plates 6 is the sum of the lengths of the testing platform 4 and the mounting frame 1. A material handling mechanism is located on the mounting plates 6. The material handling mechanism includes a fixed base 71, a sliding part 72, and a feeding plate 73. The mounting plates 6 are parallel to the surface of the testing platform 4. The fixed base 71 is vertically mounted on the mounting plates 6 and can move along the length of the mounting plates 6. The fixed base 71 contains the sliding part 72, which can move along the height of the fixed base 71. The bottom of the sliding part 72 is equipped with the feeding plate 73, which has multiple vacuum nozzles 8.

[0021] To further explain, the semi-open hopper 2 is designed with a four-rail positioning system, fully considering the rapid positioning and fixing of materials of different shapes and sizes (within the range of 100~400mm). The positioning angle and direction of the semi-open hopper 2 are consistent with the detection platform 4, and the materials are pressed before detection to avoid the problem of material warping causing deviations in the detection results. The structure of the four rails is as follows: the cross-section of the fixed base 71 is "U"-shaped, with a through groove in the middle for installing the sliding part 72. The groove wall is provided with a rail, and the corresponding position of the sliding part 72 is provided with a groove. The sliding part 72 is slidably connected to the fixed base 71. The fixed base 71 has "L"-shaped connecting parts 711 on both sides. The first plane of the connecting part 711 is connected to the side wall of the fixed base 71, and the second plane is provided with a rail. The corresponding position of the mounting plate 6 is provided with a groove, and the fixed base 71 is slidably connected to the mounting plate 6.

[0022] Further explanation: A driving cylinder is built into the sliding part 72. The driving cylinder is used to drive the sliding part 72 to move up and down and drive the fixed seat 71 to move back and forth. Preferably, a wire passing hole is provided on the front end face of the fixed seat 71. The driving cylinder is electrically connected to the fixed seat through this wire passing hole. The transverse cross-section of the sliding part 72 is "concave"-shaped, and the concave surface is close to the wire passing hole, which is convenient for wire layout.

[0023] Further explanation: The vacuum suction nozzles 8 on the detection platform 4 and the vacuum suction nozzles 8 on the loading plate 73 are both arranged in a "rice" shape. This design makes the adsorption force more uniform and ensures that the sheet material will not loosen and fall. Preferably, the vacuum suction nozzle 8 is a nozzle part made of bakelite. Bakelite material has high mechanical strength and small hardness, is easy to process and manufacture, and will not damage the sheet material when sucking the sheet material, improving the utilization rate of raw materials; a vacuum pressure gauge 731 is provided at the upper end of the loading plate 73. The vacuum pressure gauge 731 is connected to the vacuum suction nozzles 8 on the loading plate 73. The vacuum pressure gauge 731 is used to control the vacuum pressure of the vacuum suction nozzles 8. If the vacuum pressure gauge 731 is outside the normal pressure range, it indicates abnormal pressure, the vacuum suction nozzles 8 do not suck up the parts, and the machine will alarm.

[0024] For the material separating device for preventing lamination provided in this embodiment, after the sheet material is placed on the detection platform by the material taking mechanism, the vacuum suction nozzles on the detection platform will adsorb the sheet material and keep it still. The thickness sensor can quickly detect the thickness of the sheet material on the tabletop. When the actual thickness of the sheet material is greater than the set value, a signal will be fed back and an alarm will be given. At the same time, the material taking mechanism will stop taking materials, return to the detection point, suck up the top sheet material and lift it up to separate multiple sheet materials. The separated sheet materials will return to the material bin with the material taking mechanism. At the same time, the thickness sensor will re-detect the thickness of the sheet material. If the thickness is still greater than the set value, the above steps will be repeated until the detection result is within the set value range, so as to determine that there is a single sheet material on the platform. The whole device has a simple structure and is easy to operate. It can quickly and accurately identify whether there are double / multiple sheet materials, and can quickly and automatically process sheet material abnormalities. The whole process does not require manual intervention.

[0025] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
