Description

Technical Field

[0001] This utility model belongs to the field of automation technology, and specifically relates to a sliding plate measuring machine. Background Technology

[0002] There is a type of slider, as shown in the attached figure. Figure 1 As shown, it is currently necessary to measure the height H and thickness D of the slider, and then mark and classify the measured sliders. The existing inspection method involves manually inspecting the dimensions using a fixture, which is inefficient and prone to operator fatigue due to prolonged work, leading to operational or marking errors. Therefore, a slider measuring machine was designed to solve these problems.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a sliding plate measuring machine.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a sliding plate measuring machine, comprising:

[0006] The workpiece feeding unit includes a rotating feeding turntable and a fixed pushing group; several evenly distributed material box groups are arranged above the edge of the feeding turntable, and each material box group is arranged around the pushing group. The pushing group is located above the feeding turntable and is used to push out the workpieces in the material box group.

[0007] The workpiece measuring unit includes a receiving base, which has a receiving groove that can align with the push-out position of the push-out assembly. A receiving cover is provided above the receiving base, and the lower middle part of the receiving cover extends into the receiving groove.

[0008] The workpiece measuring unit includes a measuring area, which is composed of the lower end face of the receiving cover plate, the bottom surface of the receiving groove, and the two sides of the receiving groove. The area of ​​the measuring area is adapted to the shape and size of the workpiece. The lower end face of the receiving cover plate, the bottom surface of the receiving groove, and the two sides of the receiving groove are all provided with air passages that can be connected to air pipes. The air passages are located within the area of ​​the measuring area.

[0009] In this solution, the number of air passages on the lower end face of the receiving cover plate is the same as the number of air passages on the bottom surface of the receiving groove, and their positions correspond. The number of air passages on the two sides of the receiving groove is the same, and their positions correspond.

[0010] Furthermore, the material box assembly includes a feeding mounting base, a push-out port at the lower end of the feeding mounting base, a slot below the push-out port, a material box on the feeding mounting base, a vertical material slot on the outer side of the material box, and an openable material box cover outside the material slot; a receiving platform adapted to the slot is fixed below the material box, a horizontal push-out slot is provided on the receiving platform, and the push-out slot and the material slot are vertically corresponding; a bushing is provided on the inner side of the material box, and a positioning pin is provided on the feeding mounting base, the positioning pin being adapted to the bushing.

[0011] In this solution, during material loading, the material box is first manually removed, the box cover is opened, the sliding plate is filled into the material slot, and then the box cover is closed. After the material box is placed vertically, the sliding plate will fall into the pushing slot below the material box by gravity. The material box can be installed onto the loading mounting base by the cooperation of the bushing and the positioning pin, at which point the receiving platform is inserted into the slot.

[0012] Furthermore, the pushing assembly includes a pushing base, on which a reciprocating push rod is mounted. The push head of the push rod faces the pushing groove of one of the material box assemblies. The push rod is detachable. The push rod can move back and forth by connecting to a cylinder, and its linear motion is ensured by a linear guide rail. In this design, the direction of the push rod remains constant. Each station rotates sequentially to the corresponding position of the push rod via the movement of the loading turntable, driving the push rod to enter the pushing groove with its push head. Then, the sliding plate in the pushing groove pushes the material forward along the pushing direction, entering the equipment for the next process.

[0013] Furthermore, the discharge port of the receiving trough is equipped with a clamping seat, which consists of a sliding block (sliding type) and a stop block located at the lower end of the sliding block. The sliding block has a detection hole, and detection devices are provided on both sides of the detection hole. In this design, after the slider completes its measurement, it continues to push forward until it slides off the sliding block and then locks into the corner formed by the sliding block and the stop block. The detection devices on both sides of the detection hole can be through-beam optical fibers, which can detect the slider when it slides down.

[0014] Furthermore, a pressure plate is provided on one side of the receiving cover along the discharge direction, and a ball bearing is provided at the lower end of the pressure plate. The lower end of the ball bearing is configured to abut against the upper surface of the sliding plate located below it. In this design, after the sliding plate completes its detection, it continues to push forward. When passing under the pressure plate, the ball bearing rolls and presses against the upper surface of the sliding plate, making the pushing smoother.

[0015] Furthermore, a carrier is provided on one side of the receiving base, and a calibration gauge for inspecting the workpiece measuring unit is installed inside the carrier; an XYZ-axis transfer mechanism is provided on one side of the carrier, and a material-picking suction cup that can move back and forth along the X, Y, and Z axes is installed on the XYZ-axis transfer mechanism; the receiving base is located within the material-picking range of the XYZ-axis transfer mechanism. In this solution, the calibration gauge can be set to calibrate the detection accuracy of the workpiece measuring unit before measuring the slider size, ensuring the measurement accuracy of the slider. Two placement areas for placing the calibration gauge can be set on the carrier, one near the upstream of the measurement area and one near the downstream of the measurement area, to facilitate the feeding and receiving of materials by the material-picking suction cup.

[0016] Furthermore, it also includes a transport unit located downstream of the workpiece measuring unit. The transport unit includes an XZ-axis transfer mechanism with a horizontal transport frame. The transport frame has a row of evenly distributed pick-up heads. The pick-up head on the transport frame near the receiving base is the first pick-up head, which is connected to the discharge position of the receiving groove. The pick-up head can be a suction cup, and the pick-up direction of the pick-up head is towards the location of the receiving groove.

[0017] A receiving rack is provided below the conveying frame. The receiving rack has a row of material carriers for placing sliding plates. The number of material carriers is equal to the number of material picking heads, and the spacing between them corresponds one-to-one. Each material carrier has a detection element on one side. The material carrier on the receiving rack closest to the receiving base is the first material carrier. Initially, the first material carrier is positioned vertically opposite the adjacent material picking head to the first material picking head, which is located on the clamping side of the workpiece measuring unit.

[0018] In this scheme, the XZ axis transfer mechanism moves the transport frame toward the workpiece measuring unit. The sliding plate is taken out from the discharge end of the receiving groove by the first pick-up head. The XZ axis transfer mechanism moves it to the top of the receiving frame and then moves it down, so that the sliding plate on the first pick-up head is engaged with the first loading seat.

[0019] Furthermore, the system also includes an engraving unit located on one side of the receiving rack. The engraving unit includes a Z-axis lifting platform with an engraving head capable of operating in the X and Y axis regions. The engraving head is positioned above the first material pick-up head. In this solution, after the detector identifies the sliding piece entering the first material carrier, the engraving head moves down above the first material carrier and marks the sliding piece. After marking, the transport frame, carrying the material pick-up head, retrieves material from the receiving rack and moves as a whole to a side away from the engraving head, across a material carrier. The sliding piece is then inserted into the next material carrier, and the process repeats, picking up and releasing material. When a sliding piece is present in the downstream material carrier, it is removed to ensure that the downstream material carrier remains empty.

[0020] Furthermore, the system includes a robotic arm located downstream of the conveying unit. A material handling rack is positioned below the robotic arm's travel range, and this rack has a first and a second material handling plate. Both the first and second material handling plates have detection elements on their sides. In this design, the robotic arm retrieves a sliding plate from the downstream material carrier of the receiving rack, and then, according to instructions from the control system, places the sliding plate into either the first or second material handling plate. The first and second material handling plates represent qualified and rejected products, respectively. The plates can be distinguished by different colors. Once the plate is full, the detection elements provide feedback to the control system.

[0021] Furthermore, the system also includes a production line located on one side of the material handling rack, with its upstream end positioned below the travel range of the robotic arm. The production line comprises a first production line and a second production line arranged side-by-side. Both the first and second production lines are equipped with material collection bins. A movable frame, capable of moving back and forth between the two lines, is positioned between them, and the movable frame is equipped with lifting grippers. In this design, the first and second production lines flow in opposite directions. The robotic arm places a fully loaded tray into an empty material collection bin on the first production line, which then flows into the next process. Meanwhile, empty material collection bins flow out of the next process on the second production line, and the material collection bins on the second production line are transported back to the first production line by the grippers for repeated material collection.

[0022] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0023] The sliding plate measuring machine designed in this utility model adopts a pneumatic-electric conversion method, which combines pneumatic and electrical signals to achieve high-precision, non-contact dimensional detection of the sliding plate. It has a high degree of automation, saves labor costs, reduces errors caused by manual operation, is highly practical, and is suitable for widespread application. Attached Figure Description

[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0051] Example 1:

[0052] This embodiment provides a sliding plate measuring machine, see appendix. Figure 2 As shown, it includes:

[0053] Workpiece loading unit 2, see appendix Figure 3 As shown, the workpiece feeding unit 2 includes a rotating feeding turntable 3 (the feeding turntable 3 is connected to the drive device through a cam divider, which can realize the intermittent movement of the feeding turntable 3) and a fixed pushing group 4; several evenly distributed material box groups 5 are arranged above the edge of the feeding turntable 3, and each material box group 5 is arranged around the pushing group 4. The pushing group 4 is located above the feeding turntable 3 and is used to push out the workpieces in the material box group 5; one material box group 5 corresponds to one workstation.

[0054] See appendix Figure 4 and attached Figure 5 As shown, the material box assembly 5 includes a feeding mounting base 51, a push-out port 52 is provided at the lower end of the feeding mounting base 51, a slot 53 is provided below the push-out port 52, a material box 54 is provided on the feeding mounting base 51, a vertical material groove 55 is provided on the outer side of the material box 54, and an openable and closable material box cover 56 is provided outside the material groove 55 (the connection between the material box cover 56 and the material box 54 is not limited to the use of hinges, which facilitates opening; the closing and locking method between the material box cover 56 and the material box 54 is not limited to the use of quick-release structure, magnetic attraction, etc.).

[0055] Below the material box 54 is a receiving platform 57 that can be adapted to the slot 53. The receiving platform 57 has a horizontal pushing groove 58, which is vertically corresponding to the material box 55. The sliding piece 1 is stacked vertically in the material box 55 and falls from the material box 55 into the corresponding pushing groove 58 below.

[0056] The inner side of the material box 54 is provided with a bushing 59, and the feeding mounting base 51 is provided with a positioning pin. The positioning pin is adapted to the bushing 59, and the bushing 59 can be fitted onto the positioning pin.

[0057] Material loading process: During loading, the material box 54 (including the receiving platform 57 fixed at the lower end) is first removed manually. After opening the material box cover 56, the sliding plate 1 is filled into the material slot 55, and then the material box cover 56 is closed. After the material box 54 is placed vertically, the sliding plate 1 will fall into the pushing slot 58 below the material box 54 by gravity. The material box 54 can be installed onto the loading mounting base 51 by the cooperation of the bushing 59 and the positioning pin. At this time, the receiving platform 57 is inserted into the slot 53.

[0058] See appendix Figure 6 As shown, the pusher assembly 4 includes a pusher base 41, on which a pusher rod 42 that can move back and forth is mounted. The pusher head of the pusher rod 42 is positioned towards the pusher groove 58 of one of the material box assemblies 5. The pusher rod 42 is detachable. The pusher rod 42 can move back and forth by connecting to a cylinder, and its linear motion is ensured by a linear guide rail. The pusher is powered by a servo motor, which can push slides 1 of different lengths.

[0059] Material pushing process: The direction of the push rod 42 remains unchanged. Each station rotates to the corresponding position of the push rod 42 in sequence through the movement of the feeding turntable 3, drives the push rod 42 to make its push head enter the push groove 58, and then pushes the sliding plate 1 in the push groove 58 forward along the pushing direction into the equipment of the next process.

[0060] When the slider 1 falls from the material box 54, it is placed horizontally. With the pushing direction as the front, when the slider 1 is pushed out, the distance from the upper end face to the lower end face of the slider 1 is the thickness, and the distance from the left side face to the right side face is the height.

[0061] Workpiece measuring unit 6, see appendix Figure 7 Appendix Figure 8 Appendix Figure 9 and attached Figure 10 As shown, the workpiece measuring unit 6 includes a receiving base 7, on which a receiving groove 8 is provided that can align with the push-out position of the push-out group 4. A receiving cover plate 9 is provided above the receiving base 7, and the lower middle part of the receiving cover plate 9 extends into the receiving groove 8. The workpiece measuring unit 6 includes a measuring area 10, which is composed of the lower end face of the receiving cover plate 9, the bottom surface of the receiving groove 8, and the two sides of the receiving groove 8. The area of ​​the measuring area 10 is adapted to the shape and size of the workpiece. Air passages that can be connected to air pipes are provided on the lower end face of the receiving cover plate 9, the bottom surface of the receiving groove 8, and the two sides of the receiving groove 8. The air passages are located within the area of ​​the measuring area 10.

[0062] The number of air passages on the lower end face of the receiving cover plate 9 is the same as the number of air passages on the bottom surface of the receiving groove 8, and their positions correspond. The number of air passages on the two sides of the receiving groove 8 is the same, and their positions correspond. Five air passages can be provided on the lower end face of the receiving cover plate 9 and the bottom surface of the receiving groove 8, and two air passages can be provided on each of the two sides of the receiving groove 8.

[0063] The discharge port of the receiving trough 8 is equipped with a clamping seat 11, which consists of a slide block 111 and a stop block 112 located at the lower end of the slide block 111. The slide block 111 has a detection hole 113, and detection devices 12 are provided on both sides of the detection hole 113. After the slider 1 completes the measurement, it continues to be pushed forward until it slides off the slide block 111 and then gets stuck in the corner formed by the slide block 111 and the stop block 112. The detection devices 12 on both sides of the detection hole 113 can be through-beam optical fibers, which can detect the slider 1 when it slides off.

[0064] A pressure plate 13 is provided on one side of the receiving cover plate 9 along the discharge direction. A ball bearing 14 is provided at the lower end of the pressure plate 13, and the lower end of the ball bearing 14 is configured to abut against the upper end surface of the sliding plate 1 located below it. After the sliding plate 1 completes its detection, it continues to push forward. When passing under the pressure plate 13, the ball bearing 14 rolls and presses against the upper end surface of the sliding plate 1, making the pushing smoother. The ball bearing 14 and the pressure plate 13 can be connected by a tube column. The tube column is fixed inside the pressure plate 13, and the ball bearing 14 is embedded in the lower opening of the tube column and is arranged in a rolling manner.

[0065] A carrier 15 is provided on one side of the receiving base 7, and a calibration gauge 16 for detecting the workpiece measuring unit 6 is provided inside the carrier 15; an XYZ axis transfer mechanism 17 is provided on one side of the carrier 15, and a material picking suction cup 18 that can move back and forth along the three directions of X-axis, Y-axis and Z-axis is provided on the XYZ axis transfer mechanism 17; the receiving base 7 is located within the picking range of the XYZ axis transfer mechanism 17.

[0066] The setting of calibration gauge 16 can calibrate the detection accuracy of workpiece measuring unit 6 before measuring the size of slider 1, ensuring the measurement accuracy of slider 1. Two placement areas for calibrating gauge 16 can be set on carrier 15, one near the upstream of measuring area 10 and one near the downstream of measuring area 10, to facilitate the feeding and receiving of material by material chuck 18.

[0067] Measurement Principle: The workpiece measuring unit 6 measures the height and thickness of the compressor vane 1 via a gas-to-electric converter. Compressed air passes through the gap between the measuring head (air inlet) and the surface of the workpiece, creating back pressure or flow rate variations. The size of the gap (i.e., workpiece dimensional deviation) affects the gas pressure or flow rate.

[0068] Pneumatic signals (pressure / flow changes) are converted into electrical signals (voltage, current, or digital signals) by sensors (such as pressure sensors and flow sensors) to facilitate subsequent amplification, processing, and display.

[0069] Example 2:

[0070] This embodiment is a further improvement based on Embodiment 1. Specifically, it further includes a conveying unit 19 located downstream of the workpiece measuring unit 6. (See attached diagram.) Figure 11 Appendix Figure 12 and attached Figure 13 As shown, the conveying unit 19 includes an XZ axis transfer mechanism 20, on which a horizontal conveying frame 21 is provided. A row of evenly distributed picking heads is provided on the conveying frame 21. The picking head on the side of the conveying frame 21 closest to the receiving base 7 is the first picking head 22. The first picking head 22 is connected to the discharge position of the receiving groove 8. The picking head can be a suction cup, and the picking direction of the picking head is towards the position of the receiving groove 8.

[0071] Below the conveyor frame 21 is a receiving frame 23, on which a row of material carriers for placing the sliding plates 1 are arranged. The number of material carriers is equal to the number of material pick-up heads, and the spacing is corresponding. A detection element 24 is provided on one side of each material carrier. The material carrier on the receiving frame 23 closest to the receiving base 7 is the first material carrier 25. In the initial state, the first material carrier 25 and the material pick-up head adjacent to the first material pick-up head 22 are arranged vertically and vertically, and the first material pick-up head 22 is located on the side of the clamping seat 11 of the workpiece measuring unit 6.

[0072] Transportation process: The XZ axis transfer mechanism 20 moves the transport frame 21 toward the workpiece measuring unit 6. The slide plate 1 is taken out from the discharge end of the receiving groove 8 by the first pick-up head 22. The slide plate 1 is moved above the receiving frame 23 by the XZ axis transfer mechanism 20 and then moved down, so that the slide plate 1 on the first pick-up head 22 is engaged in the first loading seat 25.

[0073] Example 3:

[0074] This embodiment is a further improvement on embodiment two, specifically: it also includes an engraving unit 26, see appendix. Figure 11 and attached Figure 13 As shown, the engraving unit 26 is located on one side of the receiving rack 23. The engraving unit 26 includes a Z-axis lifting platform 27, on which an engraving head 28 that can work in the X-axis and Y-axis regions is provided; the engraving head 28 is located above the first material pick-up head 22.

[0075] Engraving process: After the detector 24 identifies that the slider 1 has entered the first material carrier 25, the engraving head 28 moves down to the top of the first material carrier 25 and marks the slider 1. The engraving content can be a QR code. After marking, the transport frame 21, carrying the picking head, picks up the material again from the receiving frame 23 and then moves as a whole to the side away from the engraving head 28 across one material carrier. Then, the slider 1 is inserted into the material carrier below, and then it returns to the previous material carrier. The picking and placing of materials is repeated. When the downstream material carrier has the slider 1, the slider 1 is removed to ensure that the downstream material carrier is empty.

[0076] In addition, the second material carrier is adjacent to the first material carrier 25. A barcode scanner 29 is installed above the second material carrier to scan and record the printed workpiece, so as to prepare for subsequent workpiece classification.

[0077] Example 4:

[0078] This embodiment is a further improvement based on Embodiment 3. The specific method is as follows: see appendix. Figure 13 As shown, it also includes a robot arm 30 located downstream of the handling unit 19. A material rack 31 is provided below the stroke range of the robot arm 30. A first tilting plate 32 and a second tilting plate 33 are provided on the tilting plate 31. Detection elements 24 are provided on the sides of both the first tilting plate 32 and the second tilting plate 33.

[0079] Material placement process: The robot arm 30 takes the slide plate 1 from the material carrier at the bottom of the receiving rack 23, and then places the slide plate 1 into the first rack 32 or the second rack 33 according to the instructions of the control system. The first rack 32 or the second rack 33 are qualified products and scrap products respectively. The racks can be distinguished by different colors. After the rack is full, the feedback is sent to the control system through the detection component 24.

[0080] See appendix Figure 14 As shown, it also includes a production line located on one side of the material rack 31, with the upstream end of the production line located below the stroke range of the robot arm 30; the production line includes a first production line 34 and a second production line 35 arranged side by side, both the first production line 34 and the second production line 35 are provided with a collection box 36, and a movable frame 37 that can move back and forth between the first production line 34 and the second production line 35 is provided between the two, and a lifting gripper 38 is provided on the movable frame 37.

[0081] Material collection process: The first production line 34 and the second production line 35 are set in opposite directions. The fully loaded tray is placed into the empty collection box 36 on the first production line 34 by the robot arm 30. The collection box 36 flows into the next process along the first production line 34. Meanwhile, the empty collection box 36 flows out from the next process on the second production line 35. The collection box 36 on the second production line 35 is transported to the first production line 34 by the gripper 38 and the material collection is repeated.

[0082] Many sensors are used in the various structures of this utility model, all of which are existing technologies, so they will not be described in detail in this document.

[0083] The sliding plate measuring machine designed in this utility model adopts a pneumatic-electric conversion method, which combines pneumatic and electrical signals to achieve high-precision, non-contact dimensional detection of the sliding plate. It has a high degree of automation, saves labor costs, reduces errors caused by manual operation, is highly practical, and is suitable for widespread application.
