DETAILED DESCRIPTION
[0026] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and implementation methods.
[0027] like Figures 1-10As shown, an embodiment of the utility model provides an automatic loading and unloading device, which is arranged on an automated grinding equipment, including: a mounting bracket 10, a material picking component 20 arranged thereon for sucking the workpiece, a detection component 30 arranged on the mounting bracket and used for detecting the workpiece, a transfer component 40 arranged on the mounting bracket and used for transferring the workpiece, and a feeding component 50 arranged on the mounting bracket for transferring the workpiece to a processing station.

[0030] It also includes: a material picking horizontal cylinder 208 arranged on the other surface of the loading vertical plate 104, a material picking cylinder connecting block 209 arranged on the material picking horizontal cylinder telescopic plate 208a, a material picking vertical cylinder 210 with one side fixedly connected to the material picking cylinder connecting block, a material moving connecting plate 211 connected to the material picking vertical cylinder telescopic plate 210a and located below it, two first suction cup mounting parts 212 vertically connected to the material moving connecting plate and respectively located on both sides of the material picking vertical cylinder telescopic plate, and two first suction cups 213 respectively arranged at the lower ends of the two first suction cup mounting parts; the material moving connecting plate 211 is located above the two first half clamps 207.
[0031] The detection assembly 30 includes: a measuring cylinder mounting plate 301 with a lower end vertically connected to the feeding bottom plate 101, a measuring cylinder 302 provided on the measuring cylinder mounting plate and arranged longitudinally, an electronic detection meter 303 connected to the measuring cylinder telescopic plate 302a, a meter head 304 provided on the upper surface of the electronic detection meter, a detection connecting sleeve 305 axially sleeved on the outside of the meter head and fixedly connected to the meter head, a detection contact 306 axially sleeved on the upper end of the detection connecting sleeve, a detection contact 306 provided on the upper surface of the measuring cylinder telescopic plate 302a and sleeved The detection mounting plate 307 is located outside the detection connecting sleeve; the detection contacts are located below the two first half clamps 207; the electronic detection meter 303 here is indirectly connected to the measuring cylinder telescopic plate 302a through the detection mounting plate 307; the electronic detection meter 303 is a commercially available standard part, which includes a meter head 304, and a retractable rod 304a is provided at the upper end of the meter head; the meter head 304 and the rod are arranged along the axial direction of the detection contact 306 and the detection connecting sleeve 305, and the upper end of the rod 304a protrudes from the upper end of the detection contact for detecting the workpiece, such as Figure 11 shown.
[0032] like Figure 11As shown, this embodiment is explained by taking the processing of the concave surface of the workpiece 70 with concave and convex surfaces as an example. The curvature radius of the non-processed surface (convex surface) is set in the electronic control panel of the loading and unloading device, and the curvature radii of the concave surface and the convex surface are different. For the needs of subsequent processing, the processing surface of the workpiece clamped by the two first half clamps 207 must face upward, that is, the concave surface must face upward, and the detection contact is located below the two first half clamps 207. Therefore, the detection contact actually detects the reverse side of the processing surface of the workpiece 70, that is, the curvature radius of the convex surface. If the detected If the data is consistent with the set data, the concave surface (processing surface) must be facing upwards, which meets the requirements and continues to the next step; on the contrary, if the detected data is consistent with the set data, the concave surface (processing surface) must be facing downwards, and the electronic detection table 303 sends a command to the electronic control board of the grinding equipment and drives the material-taking vertical cylinder 210 to start, driving the two first suction cups 213 to rise and make the first suction cup on the right side separate from the two first half clamps, and the measuring cylinder 302 drives the detection contact 306 to descend, and at the same time the first finger cylinder 205 is started to drive The two first half clamps are closed and clamp the workpiece, and then the swing cylinder 202 is started, driving the swing cylinder connector 204, the first finger cylinder 205, the two first half clamps and the workpiece to rotate 180 degrees, that is, the workpiece is turned 180 degrees so that the concave surface faces upward; therefore, the workpiece has only two surfaces at this point, and if the detected surface does not meet the requirements, the other surface must meet the requirements; specifically, the relative position of the electronic test table 303 and the detection contact 306 remains unchanged, fixed on the measuring cylinder telescopic plate 302a, and moves up and down synchronously; the workpiece is clamped by the two first half clamps 20 7 clamping, is also relatively static; the measuring cylinder telescopic plate 302a is driven by the measuring cylinder 302, and during the rising process, the rod 304a first contacts the workpiece 70 and at this time the electronic detection meter 303 and the detection contact continue to rise, the rod abuts against the workpiece and retracts until the detection contact 306 touches the workpiece 70, and the meter head 304 starts detection; because the workpiece 70 is a lens with concave and convex surfaces, the concave surface and the convex surface have different curvature radii, and then the electronic detection meter 303 displays different values, which are transmitted to the electronic control board through the data line 80 for logical judgment. For example, a reference value of -12.01±0.02 is set in the system of the device, Figure 11 The value displayed by the electronic detection table in the left figure is -12.35, which exceeds the set value range, and the workpiece needs to be turned over; Figure 11 The electronic inspection meter in the right figure shows a value of -12.03. If the value is within the set range, the workpiece does not need to be flipped. This test determines whether the orientation of the workpiece's machined surface meets the requirements, thus avoiding any impact on subsequent processing steps. It should be noted that the two values here are merely examples, not actual values. In the actual measurement process, there is no need to measure specific values; only comparison with the set values is used to determine whether the workpiece needs to be flipped.
[0033] Although the present embodiment is described with reference to the detection of a workpiece 70 having concave and convex surfaces, it is obvious to those skilled in the art that the same effect can be achieved by using the detection component to detect other workpieces comprising two surfaces with different features, such as a workpiece having a concave surface and a flat surface, a workpiece having a convex surface and a flat surface, a workpiece having an inclined surface and a flat surface, etc.
[0034] In this embodiment, if Figure 5-Figure 6 As shown, the material taking horizontal cylinder 208 is a commercially available standard part, which includes the material taking horizontal cylinder telescopic rod, which are all existing technologies.

Figure 4-Figure 5 As shown, a cover plate 413 is provided on one surface of the longitudinal slide 402 .
[0036] The apparatus further comprises: a rotary cylinder 406 fixed to the front surface of the longitudinal slide 403; a feed mounting plate 407 connected to a rotating disk 406a mounted on the rotary cylinder; a feed mounting horizontal plate 408 with one end perpendicularly connected to the upper end of the feed mounting plate; a second finger cylinder 409 mounted on the upper surface of the feed mounting horizontal plate; two second pneumatic fingers 409a movably mounted on the second finger cylinder in parallel with each other; two second connecting rods 410 respectively fixed to the outer surfaces of the two second pneumatic fingers; and two second half clamps 411 respectively mounted at the front ends of the two second connecting rods. A cylindrical pad 412 is provided on the feed mounting horizontal plate 408, located below and abutting the two second half clamps 411.
[0037] The feeding assembly 50 includes: a cylinder mounting plate 501 whose lower end is vertically connected to the loading base plate 101 and is located below the loading flat plate 103, a feeding cylinder 502 arranged on the outer surface of the cylinder mounting plate, two feeding slide rails 503 parallel to each other and arranged on the inner surface of the cylinder mounting plate, two feeding sliders 504 movably arranged on the two feeding slide rails, a feeding moving plate 505 whose outer surface is fixedly connected to the two feeding sliders and is parallel to the cylinder mounting plate, a cylinder connecting plate 506 fixedly arranged on the outer surface of the feeding moving plate and vertically connected to the feeding cylinder telescopic rod 502a, a feeding motor mounting plate 507 arranged on the inner surface of the feeding moving plate and perpendicular to it, a feeding motor 508 arranged on one surface of the feeding motor mounting plate, and a feeding motor 509 arranged on the feeding motor mounting plate. The feeding coupling 509 is located on the other surface of the machine mounting plate and is connected to the output end of the feeding motor. There are two bearing seats 510 provided on the inner surface of the feeding movable plate and having built-in bearings. A feeding shaft 511 is connected to the feeding coupling at one end. The feeding shaft is installed on the two bearing seats 510. The bearing (not shown) built into the bearing seat is sleeved on the feeding shaft 511. A material arm fixing plate 512 is vertically connected to the other end of the feeding shaft at one end and is located on the outside of one end of the feeding movable plate 505. An adjusting fixing block 513 is provided on the inner surface of the material arm fixing plate. There are two material arms 514, one end of each material arm is connected to the adjusting fixing block and is located on the inside of the material arm fixing plate. Two second suction cups 515 are provided at the other end of the two material arms. The feeding cylinder 502 is a commercially available standard part, which includes a feeding cylinder telescopic rod 502a, such as Figure 3 、 Figure 5 As shown, the telescopic rod of the feeding cylinder is a part of the feeding cylinder 502.
[0038] With the above structure, the vibrating hopper 60 continuously transfers the workpiece to the hopper guard 601 during operation, and the horizontal cylinder 208 for picking up the material is started, which drives the vertical cylinder 210 for picking up the material to move, and drives the material transfer connecting plate 211, the first suction cup mounting member 212 and the two first suction cups 213 to move. For example, if the first suction cup on the left has not picked up the workpiece and the suction cup on the right has picked up the workpiece as the initial state, the first suction cup on the left has reached above the hopper guard 601, and the first suction cup on the right has reached above the two first half clamps 207 (as shown in FIG. Figure 4As shown), the material-taking vertical cylinder 210 is then started, driving the two first suction cups 213 to move downward, the first suction cup on the left side picks up a workpiece, and the first suction cup on the right side extends into the two first half clamps 207. At this time, the measuring cylinder 302 drives the electronic detection meter 303 and the detection contact 306 to rise so that the detection contact is located under the first suction cup on the right side. The header 304 of the electronic detection meter detects whether it is within the set value range. At this time, the two first half clamps are separated and will not clamp the workpiece. If the detection result is within the set range, the material-taking vertical cylinder 210 is started and drives the two first suction cups 213 to rise so that the first suction cup on the right side drives the detected workpiece to separate. The material-taking horizontal cylinder 208 is started again, driving the two first suction cups 213 to move until the first suction cup on the right side reaches the two second half clamps 41 1 and the first suction cup on the left reaches above the two first half clamps 207, and then the material taking vertical cylinder 210 drives the two first suction cups 213 to descend, and the first suction cup on the left sends the workpiece to the detection position for detection and is clamped by the two first half clamps 207, and the first suction cup on the right sends the detected workpiece to the two second half clamps 411 and starts the second finger cylinder 409 to drive the two second half clamps to clamp the workpiece. After completing this action, the two first suction cups 213 return to their initial positions in turn under the drive of the material taking vertical cylinder 210 and the material taking horizontal cylinder 208, that is, the first suction cup on the left reaches above the hopper guard 601, and the first suction cup on the right reaches above the two first half clamps 207 and waits to absorb the detected workpiece, and then the two first suction cups repeat the above-mentioned actions; at the same time, Figures 1-4 As shown, the rotary cylinder 406 is started, driving the feeding mounting plate 407, the feeding mounting horizontal plate 408, the second finger cylinder 409, the second pneumatic finger 409a, and the second half clamp 411 to rotate 90 degrees clockwise; Figures 1-4 As shown, here the two second suction cups 515 are in the position where neither of them sucks the workpiece, which is the initial state. Then the feeding cylinder 502 is started to drive the feeding motor mounting plate 507, the feeding motor 508, the material arm fixing plate 512, the material arm 514, and the second suction cup 515 to move forward as a whole to the set position. Then the feeding motor is started and drives the material arm fixing plate 512, the material arm 514, and the second suction cup 515 to rotate clockwise as a whole until one of the second suction cups (specifically the second suction cup 515 located at the top in the initial state) reaches the second half clamp 411, and the second suction cup sucks the workpiece to be processed there, as shown in FIG. Figure 2 Then the feeding motor reverses and drives the two second suction cups 515 to rotate counterclockwise as a whole, as shown in the direction of the arrow; Figure 4 At this time, the workpiece processing position of the automatic grinding equipment is completed, and when the feeding motor drives the second suction cup that has not sucked the workpiece (specifically, the second suction cup located at the bottom in the initial state) to reach the position where the workpiece is processed. Figure 1After the workpiece is processed at position D, the feeding motor stops until the second suction cup that has not yet sucked up the workpiece sucks up the finished workpiece. The feeding motor then starts and continues to drive the two second suction cups to rotate counterclockwise until the second suction cup that sucked up the workpiece to be processed reaches position D and feeds the workpiece to be processed into the workpiece processing position, thus completing the feeding action of the grinding process. At this time, the feeding motor starts and reverses, driving the two second suction cups to rotate clockwise. When the second suction cup that sucked up the finished workpiece reaches the unloading position, the feeding motor stops, the second suction cup releases, and the finished workpiece falls into the receiving frame, thus completing the unloading, thus completing the entire loading, feeding, and unloading action. The vibrating hopper 60 here is a commercially available standard part.
[0039] If the electronic inspection meter finds that the workpiece is not within the set range, it sends a command to the grinding equipment's electronic control board, which activates the material removal vertical cylinder 210 and drives the two first suction cups 213 to rise and separate the first suction cup on the right from the two first half clamps. The measuring cylinder 302 drives the detection contact 306 downward. At the same time, the first finger cylinder 205 is activated, driving the two first half clamps to close and clamp the workpiece. The swing cylinder 202 is then activated, driving the swing cylinder connector 204, the first finger cylinder 205, the two first half clamps, and the workpiece to rotate 180 degrees, that is, the workpiece is flipped 180 degrees. In this case, the workpiece has only two surfaces, and one surface must meet the requirements. Therefore, the workpiece is flipped 180 degrees, the first finger cylinder 205 is activated and releases the workpiece, and then one of the first suction cups 213 picks up the workpiece for subsequent operations. The action of sending a command to the grinding equipment's electronic control board when the electronic inspection meter finds that the workpiece is not within the set range is common in general automation equipment and belongs to the prior art, so it will not be repeated here.
