Detailed implementation manners

[0029] The following describes the present utility model in detail with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present utility model, but do not limit the present utility model in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several changes and improvements can still be made.

[0030] Example 1

[0031] This embodiment provides a door opening device, as Figures 1-7 shown, including an upper board machine 10, a frame 11, a mounting seat 12, a vertical board 13, an opening 14, a carrier table 20 and a door opening module 30. The frame 11 is arranged on the upper board machine 10. The frame 11 includes a mounting seat 12 and a vertical board 13. The vertical board 13 is vertically installed on the upper surface of the mounting seat 12, and two uniformly distributed openings 14 are provided on the vertical board 13.

[0032] As Figure 2 shown, the carrier table 20 is fixed on the mounting seat 12 and is located at a position below the corresponding opening 14, and includes a base 21, a Y-axis linear drive module 22 installed on the base 21, a moving platform 23 driven by the Y-axis linear drive module 22, and a positioning mechanism 24 arranged on the upper surface of the moving platform 23. The carrier table 20 is used to receive the material box conveyed by the trolley, accurately position the position of the material box, and convey it to the door opening module 30. Preferably, the Y-axis linear drive module 22 adopts a linear module driven by a servo motor.

[0033] As shown Figure 3 in the figure, the positioning mechanism 24 includes a sensor 201, opposite air cylinders 29 disposed on the left and right sides of the upper surface of the moving platform 23, a first convex block 25 driven by the air cylinders 29, and a plurality of floating centering units 26 disposed on the upper surface of the moving platform 23. The sensors 201 are respectively located inside the four floating centering units 26. By measuring the height of the bottom surface of the cartridge with the sensors, it is possible to prevent the cartridge from not being placed flat and thus tilting. After the sensors 201 transmit information, the control system in the system adjusts the output signal of the pressure regulating valve 202. During the actual centering process, there is a pressure difference between the two air cylinders 29, and the pressure difference meets the friction requirement. The minimum thrust of the air cylinder is greater than the friction force, and the fine adjustment of the bottom of the cartridge is achieved through the air cylinder. Optionally, the first convex block 25 has a V-shaped structure and has two semi-circular protruding portions 251. The number of floating centering units 26 is 4. The floating centering unit 26 uses a double-row thrust ball bearing, and the cartridge is directly placed on it, making the friction force smaller. The floating centering unit 26 has the function of floating support displacement, so that the heavy object located on it can float and displace under the action of an external force. A pair of guide rails 27 are fixed on the top surface of the base 21. A slider 28 is provided on the guide rail 27. The moving platform 23 is fixed on the slider 28.

[0034] As shown Figure 4 in the figure, the door opening module 30 includes a Z-axis linear drive module 31, a door panel 32, a second slide rail 36, and a slide seat 37. The Z-axis linear drive module 31 is vertically installed on one side of the opening 14 of the frame 11, the second slide rail 36 is installed on the other side of the opening 14, a slide seat 37 is provided on the second slide rail 36, and the door panel 32 is fixed on the slide seat 37.

[0035] Working principle: When the cartridge is placed on the upper surface of the floating centering unit 26, the air cylinders 29 drive the first convex block 25 to move towards the cartridge, and under the floating support of the floating centering unit 26, the cartridge is pushed, achieving precise positioning of the cartridge and reducing the friction force generated when the air cylinders 29 push the cartridge. Since the strokes of the two air cylinders 29 are the same, the cartridge will be pushed towards the middle, achieving left and right centering. After adjusting the position of the cartridge, the Y-axis linear drive module 22 drives the moving platform 23, carrying the cartridge, and moves towards the door opening device 30.

[0036] Example 2

[0037] This embodiment provides a chip processing device, including the door opening device in Embodiment 1, as shown Figures 3-7As shown in the figure, it further includes a feed bin, specifically as follows: The bottom surface of the feed bin has a second bump 16 that cooperates with the first bump 25. The second bump 16 is in a W-shaped structure and has an isosceles triangle notch 161 that is adapted to the semi-circular protruding part 251. Since the strokes of the two cylinders 29 are the same, the feed bin will be pushed towards the middle, achieving left and right centering positioning. At the same time, the two protruding parts 251 of the first bump 25 are inserted into the two notches 161 of the second bump 16, thereby achieving front and rear position positioning of the feed bin.

[0038] The door opening device 30 is located at the opening 14 on the vertical plate 13 and is on the same side as the carrier 20, and includes a Z-axis linear drive module 31 vertically installed on one side of the opening 14 and a door panel 32 driven by the Z-axis linear drive module 31. Among them, the box body of the feed bin and the feed bin door 152 are detachably connected. In this embodiment, plugs 34 are provided at the four corners of the outer surface and the four corners of the inner surface of the feed bin door 152. As Figure 7 shown, jacks 171 are provided at the positions corresponding to the plugs on the door frame 17 of the box body. The jack 171 is composed of a large hole 172 in the middle and small holes 173 that communicate with the large hole 172 and are respectively located above and below the large hole. The ball head diameter of the plug 34 is smaller than the aperture of the large hole 172 of the jack 171 and larger than the apertures of the two small holes 173. In this way, when installing the feed bin door 152, the plug 34 is inserted from the large hole 172 of the jack 171, and by the self-weight of the feed bin door 152, the plug 34 falls into the lower small hole 173 to form an interlocking structure with the jack 171, so that the feed bin door 152 is fixed on the feed bin body. When separating the feed bin door 152, the feed bin door 152 is slightly lifted. When it is at the position of the large hole 172, the feed bin door 152 is moved away from the feed bin, so that the plug 34 is pulled out from the large hole 172 of the jack 171, thereby realizing the separation of the feed bin door 152 from the feed bin. The Z-axis linear drive module 31 is a linear module driven by a servo motor.

[0039] In addition, a connection structure 33 is provided between the feed bin door 152 and the door panel 32 to realize the combination and separation of the door and the feed bin through this connection structure 33. This connection structure can be operated by a simple manipulator or a suction cup structure, etc. In this embodiment, the connection structure 33 is composed of four plugs 34 provided on the outer surface of the feed bin door 152 of the feed bin and slots 35 provided at the positions corresponding to the plugs 34 on the door panel 32. As Figure 6As shown in the figure, the slot 35 is composed of a large notch 351 located in the upper part and a small notch 352 located in the lower part and communicating with the large notch 351. The diameter of the end of the plug 34 is smaller than the large notch 351 of the slot 35 and larger than the small notch 352. The Y-axis linear drive module 22 drives the moving platform 23, carrying the material box, to move towards the door panel 32 until the plug 34 on the outer surface of the material box door 152 is inserted from the large notch 351 of the slot 35. Then the Z-axis linear drive module 31 drives the door panel 32 to rise slightly, and the plug 34 falls into the small notch 352 of the slot 35, so that the door 321 is fixed on the door panel 32.

[0040] Working principle: The trolley places the material box on the floating centering unit 26. The starting cylinder 29 is driven to drive the first convex block 25 to move towards the second convex block 16 at the bottom of the material box. The first convex block 25 is inserted into the second convex block 16, and under the floating support of the floating centering unit 26, the material box is pushed to achieve precise positioning of the material box. The Y-axis linear drive module 22 drives the moving platform 23 to carry the material box and move towards the door panel 32 until the plug 34 on the outer surface of the material box door 152 is inserted from the large notch 351 of the slot 35. Then, the Z-axis linear drive module 31 drives the door panel 32 to rise slightly, and the plug 34 falls into the small notch 352 of the slot 35, so that the material box door 152 is fixed on the door panel 32. Then, the Y-axis linear drive module 22 drives the moving platform 23 to carry the material box and retreat, so that the material box door 152 is separated from the material box. The Z-axis linear drive module 31 drives the door panel 32 to continue to rise with the door 321. After the door panel 32 reaches the highest position, the Y-axis linear drive module 22 drives the moving platform 23 to carry the material box and move to the opening 14, and finally pick up the chips in the material box or store the chips in the material box. After completion, the Y-axis linear drive module 22 first drives the moving platform 23 to carry the material box and retreat, the Z-axis linear drive module 31 drives the door panel 32 to lower with the material box door 152, and the Y-axis linear drive module 22 then drives the moving platform 23 to carry the material box and move forward. After the box body of the material box is connected to the material box door 152, the Y-axis linear drive module 22 drives the moving platform 23 to carry the material box and retreat, so that the material box door 152 is separated from the door panel 32, and the trolley transports the material box away. Then continue to perform reciprocating motion.
