Description

Technical Field

[0001] This utility model relates to the field of superhard material synthesis and production, specifically to a device for measuring the weight and height of a superhard material graphite column. Background Technology

[0002] In the superhard materials synthesis industry, graphite columns are a key production raw material. The accuracy of their weight and height dimensions directly affects the quality and efficiency of subsequent superhard material synthesis. Therefore, strict weight and height testing is required after the graphite columns are pressed.

[0003] Currently, the industry mostly uses manual operation mode to detect the weight and height of graphite columns. Specifically, staff manually transport the graphite columns pressed by the four-column hydraulic press to the electronic balance for weight measurement, and then transfer the graphite columns that meet the weight requirements to the height measuring tool for height detection. During this process, the graphite columns that do not meet the weight or height requirements need to be manually sorted out, and the qualified graphite columns are transported to the packaging area.

[0004] Existing testing methods suffer from drawbacks such as the high manpower and time consumption of manual handling and measurement processes. Especially in the context of mass production of graphite columns, the testing efficiency is extremely low and it is difficult to match the continuous operation efficiency of the production line. At the same time, manual operation is easily affected by human factors such as measurement methods and visual judgment errors, resulting in unstable weight and height detection accuracy, which cannot meet the requirements for production efficiency and measurement accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a device for measuring the weight and height of a superhard graphite column in order to solve the above problems. By setting up a track, electronic balance, infrared height limit device and robotic arm, the device realizes the fully automated operation of the graphite column from output of the repressing machine, detection and picking of defective products. It eliminates the need for manual handling, manual measurement and sorting, reduces manpower input, and meets the high-efficiency operation requirements of industrial production. See the following description for details.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides an automated device for detecting the weight and height of graphite columns, including a four-column hydraulic press arranged laterally and a track. An electronic balance is provided below the input end of the track, which corresponds to the graphite column weight detection position of the track. An infrared height limiting device is provided on the side of the track downstream of the electronic balance, which corresponds to the graphite column height detection position of the track.

[0008] A first robotic arm is installed on the outside of the track next to the electronic balance to grab and transfer graphite columns that fail the weight test; a second robotic arm is installed on the outside of the track next to the infrared height limiting device to grab and transfer graphite columns that fail the height test; the graphite columns pressed by the four-column hydraulic press are conveyed by the track to complete the weight test of the electronic balance and the height test of the infrared height limiting device in succession.

[0009] The device for measuring the weight and height of a superhard graphite column employs the aforementioned method. The graphite column, after being pressed into shape by a re-pressing machine, is conveyed from the output end of the re-pressing machine along a guide assembly and a feeding assembly to the input end of a track. Simultaneously, the track drive system is activated, causing the track to stably transport the graphite column at a preset speed. When the graphite column is conveyed by the track to the corresponding detection position of the electronic balance, the electronic balance detects the weight of the graphite column and provides real-time feedback of the detection data. If the detection result shows that the weight of the graphite column is unqualified, the control system triggers the action of the first robotic arm at the corresponding position. The first robotic arm grabs and removes the graphite column with unqualified weight. If the weight detection is qualified, the graphite column continues to be conveyed to the next detection stage by the track. When the graphite column with qualified weight is conveyed by the track to the detection position corresponding to the infrared height limiting device, the horizontally placed infrared height limiting device detects the height of the graphite column to determine whether its height meets the qualified standard. If the detection result shows that the height is unqualified, the control system triggers the action of the second robotic arm at the corresponding position. The second robotic arm grabs and removes the graphite column with unqualified height. If the height detection is qualified, the graphite column continues to be conveyed by the track.

[0010] Specifically, during the feeding process of the four-column hydraulic press onto the track, the graphite columns enter the inner side of the guide assembly's track from the four-column hydraulic press. Multiple graphite columns are guided by the converging part of two sets of support plates to roll and adhere closely along the track towards the side plate. Rotating the knob drives the screw to rotate, and the two sets of external threads with opposite directions drive the two sets of support plates to slide in opposite directions, thereby adjusting the distance between the two sets of support plates to match the length of the corresponding graphite columns. This ensures that the rolling channel formed between the two sets of support plates can guide the graphite columns to roll smoothly downwards along the slope, arranging them parallel and closely along the track near the hopper end, forming a row of graphite columns awaiting inspection. When it is necessary to place the graphite columns one by one onto the track for inspection, the lifting mechanism is used... The push rod pushes the top movable plate upwards, so that the lowest graphite column is pushed upwards along the side plate to the feed inlet position through the support plate. At the same time, the baffle plate blocks the adjacent graphite column, so as to ensure that only one graphite column is pushed into the hopper at a time. The graphite column falling into the hopper through the feed inlet is blocked by the limiting column at one end, thereby adjusting the graphite column from a parallel state to an inclined state during the falling process. At this time, the graphite column can rotate and roll along the inner wall of the hopper and fall vertically into the balance tube, so as to adjust the graphite column from a horizontal state to a vertical state. At the same time, it falls onto the top surface of the track, so as to keep the graphite column upright on the track and follow the track to detach from the balance tube through the discharge hole, realizing the process of discharging a single graphite column onto the track.

[0011] Preferably, the system also includes a guide assembly disposed between the four-column hydraulic press and the track. The guide assembly is inclined along the extension direction of the track to guide the graphite column from the output end of the four-column hydraulic press onto the track. A feeding assembly is provided on one side of the guide assembly extending above the input end of the track to guide the graphite column pressed by the four-column hydraulic press to stand upright and be conveyed onto the track.

[0012] Preferably, the feeding assembly includes a hopper and a side plate fixed to one side of the hopper. The top of the hopper is provided with a feed inlet for mounting the side plate, and the feed inlet corresponds to the graphite column output end of the four-column hydraulic press. The side plate extends vertically and is fixed to the outer wall of the hopper. The top edge of the side plate extends into the inner side of the hopper and is provided with multiple limiting holes, and one of the limiting holes is threaded with an outwardly protruding limiting post.

[0013] Preferably, the hopper has a conical structure and a balance tube is provided at the bottom of the hopper. One end of the balance tube is connected to the bottom of the hopper, and the other end extends toward the track and is located above the track. The end of the balance tube away from the guide assembly has a discharge hole for accommodating the graphite column to come out. The discharge hole is positioned toward the conveying surface of the track.

[0014] Preferably, the guide assembly includes an inclined track extending beyond the side plate. A receiving groove is formed on the side of the track facing the track, and a movable plate is disposed inside the receiving groove. The movable plate includes a support plate and a baffle plate connected to each other. The baffle plate is fixed to the side of the support plate away from the center of the track, and the support plate is used to support the graphite column. The baffle plate is used to prevent adjacent graphite columns from moving along the track direction. A lifting push rod is disposed inside the movable plate, and the lifting push rod is fixedly connected to the side plate externally. It is used to drive the movable plate to rise and fall vertically to push the lowest graphite column along the side plate into the hopper.

[0015] Preferably, the guide assembly further includes two sets of symmetrically distributed support plates. The support plates extend outward from the side away from the track center to form a converging part. The converging part is an outwardly inclined slope used to gather the offset graphite columns to the center of the track and roll them downward. The middle of the track is symmetrically provided with two sets of grooves that accommodate the support plates to be embedded and slide. The bottom surface of the track below the groove is rotatably provided with a longitudinally extending screw. The two ends of the screw are provided with two sets of external threads with opposite directions. The screw is threaded with the two sets of support plates through the two sets of external threads respectively. Both ends of the screw are fixedly connected with knobs. By rotating the knobs, the two sets of support plates can be driven to move in opposite directions to adjust the spacing.

[0016] Preferably, the system also includes a motor for driving the tracks, the motor being connected to the drive wheel of the tracks.

[0017] Preferably, the electronic balance is positioned directly below the conveying surface of the track, and the detection area of ​​the electronic balance corresponds to the graphite column conveying path of the track. The electronic balance is electrically connected to an external control system, which can transmit the weight detection data to the control system, and the control system controls the gripping action of the first robotic arm.

[0018] Preferably, the infrared height limiting device is horizontally fixed to the top surface of the track, and the detection end of the infrared height limiting device is vertically oriented towards the conveying surface of the track. The infrared height limiting device is electrically connected to an external control system, which can transmit the height detection data to the control system. The control system controls the grasping action of the second robotic arm, and the detection height of the infrared height limiting device can be adjusted according to the qualified height threshold of the graphite column.

[0019] Preferably, both the first and second robotic arms are fixedly connected to the outside of the track via a fixed base, and the gripping ends of both are located directly above the track. The gripping range of the first robotic arm covers the track detection position corresponding to the electronic balance, and the gripping range of the second robotic arm covers the track detection position corresponding to the infrared height limiting device.

[0020] The beneficial effects are as follows: This utility model realizes the fully automated operation of graphite column output from the represser, detection and picking out of defective products by setting up a track, electronic balance, infrared height limit device and robotic arm. It eliminates the need for manual handling, manual measurement and sorting, reduces manpower input and meets the high-efficiency operation requirements of industrial production.

[0021] The feeding assembly, in conjunction with the lifting push rod, support plate, and baffle plate of the guide assembly, enables the feeding of individual graphite columns one by one. With the help of the hopper, balance tube, and limit post, the graphite column is adjusted from a horizontal state to a vertical state and stands upright on the track, preventing the graphite column from shifting or tipping over during the feeding process and affecting the test results.

[0022] In addition, adjustable support plates are set up as constraint components to guide the graphite columns to roll one by one and arrange them in the track. This can be used for graphite columns of different lengths, increasing the versatility of the equipment, ensuring the continuous transport of graphite columns to be inspected on the track, and ensuring inspection efficiency.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] See Figures 1-7 As shown, this utility model provides an automated device for detecting the weight and height of graphite columns, including a four-column hydraulic press 1 arranged laterally and a track 2. The four-column hydraulic press 1 is used to produce graphite columns, and this equipment is existing technology in the field, so it will not be described in detail here. An electronic balance 3 is provided below the input end of the track 2. The electronic balance 3 corresponds to the graphite column weight detection position of the track 2. An infrared height limiting device 4 is provided on the side of the track 2 downstream of the electronic balance 3. The infrared height limiting device 4 corresponds to the graphite column height detection position of the track 2.

[0035] A first robotic arm 5 is installed on the outside of the track 2 next to the electronic balance 3. It is used to grab and transfer graphite columns that fail the weight test, thereby quickly separating the unqualified products and preventing them from entering the subsequent height test stage. A second robotic arm 6 is installed on the outside of the track 2 next to the infrared height limiting device 4. It is used to grab and transfer graphite columns that fail the height test, thereby accurately rejecting products that do not meet the height requirements and ensuring that the graphite columns entering the packaging stage meet the size requirements. The graphite columns pressed by the four-column hydraulic press 1 are conveyed by the track 2 and successively complete the weight test of the electronic balance 3 and the height test of the infrared height limiting device 4, thereby realizing the screening of the weight and height of the graphite columns one by one.

[0036] As an optional implementation, a guide assembly 9 is also included, which is disposed between the four-column hydraulic press and the track 2. The guide assembly 9 is inclined along the extension direction of the track 2 to guide the graphite column from the output end of the four-column hydraulic press to the track 2. By using the gravity of the inclined structure, the jamming problem during the transmission of the graphite column is reduced, and the feeding continuity is ensured. A discharge assembly 8 is disposed on the side above the input end of the track 2, which is used to guide the graphite column pressed by the four-column hydraulic press 1 to stand upright and be transported to the track 2. With this configuration, the directional conveying of the guide assembly 9 and the posture adjustment of the discharge assembly 8 can be coordinated to ensure that the graphite column enters the detection stage with a uniform vertical posture, avoiding the deviation of the detection data due to the skewed posture.

[0037] The feeding assembly 8 includes a hopper 801 and a side plate 802 fixed to one side of the hopper 801. The top of the hopper 801 is provided with a feed inlet 801a for mounting the side plate 802, and the feed inlet 801a corresponds to the graphite column output end of the four-column hydraulic press 1. The side plate 802 extends vertically and is fixed to the outer wall of the hopper 801. The top edge of the side plate 802 extends into the inner side of the hopper 801 and is provided with multiple limiting holes 802a. One of the limiting holes 802a is threaded with an outwardly protruding limiting post 804. By adjusting the limiting post 804 installed in the limiting hole 802a at different positions, it can be adapted to use graphite columns of different lengths. This setting can flexibly adapt to the posture adjustment needs of graphite columns of various specifications, and can meet different production scenarios without replacing the feeding assembly 8, thus reducing equipment adaptation costs.

[0038] The hopper 801 has a conical structure. A balance tube 803 is provided at the bottom of the hopper 801. One end of the balance tube 803 is connected to the bottom of the hopper 801, and the other end extends towards the track 2 and is located above the track 2. The end of the balance tube 803 away from the guide component 9 has a discharge hole 803a to accommodate the graphite column. The discharge hole 803a is set towards the conveying surface of the track 2. With this configuration, the conical structure of the hopper 801 can guide the graphite column to roll along the inner wall and move smoothly downward. The balance tube 803 can further stabilize the vertical posture of the graphite column and ensure that the graphite column stands accurately on the top surface of the track 2 when it comes out of the discharge hole 803a, avoiding deviation.

[0039] The guide assembly 9 includes an inclined track 901 that extends to the outside of the side plate 802, thereby realizing the transmission connection between the guide assembly 9 and the unloading assembly 8. This allows the graphite column to transition directly from the track 901 to the unloading assembly 8, reducing the transmission gap. The track 901 has a receiving groove 901a on the side facing the track 2. A movable plate 902 is provided inside the receiving groove. The movable plate 902 includes a support plate 902a and a baffle plate 902b connected to each other. The baffle plate 902b is fixed to the side of the support plate 902a away from the center of the track 2, and the support plate 902a is used to lift. The graphite column is stably supported by a baffle plate 902b to prevent adjacent graphite columns from moving along the direction of the track 901, thus ensuring the orderly conveying of a single graphite column. A lifting push rod 903 is provided on the inner side of the movable plate 902. The lifting push rod 903 is fixedly connected to the side plate 802 and is used to drive the movable plate 902 to rise and fall in the vertical direction to push the bottom graphite column along the side plate 802 into the hopper 801. This setting facilitates the feeding of graphite columns one by one, avoids multiple graphite columns entering the hopper 801 at the same time and causing congestion, and improves the feeding accuracy.

[0040] The guide assembly 9 also includes two sets of symmetrically distributed support plates 905. The support plates 905 extend outward from the side away from the center of the track 2 to form a converging part 905a. The converging part 905a is an outwardly inclined slope, used to converge the offset graphite columns to the center of the track 901 and arrange them downward. The middle of the track 901 is symmetrically provided with two sets of grooves 904 for accommodating the middle of the support plates 905 and allowing them to slide. The bottom surface of the track 901 below the grooves 904 is rotatably provided with a longitudinally extending screw 906. The screw 906 has two sets of external threads 906a with opposite directions at both ends. The screw 906 is threaded with two sets of support plates 905 through the two sets of external threads 906a respectively. Both ends of the screw 906 are fixed with knobs 906b. By rotating the knobs 906b, the two sets of support plates 905 can be driven to move in opposite directions to adjust the spacing. This allows the spacing of the support plates 905 to be flexibly adjusted according to the actual length of the graphite column, ensuring that graphite columns of different specifications can be stably conveyed in the center of the track 901, thus improving the versatility of the guide assembly 9.

[0041] It also includes a motor 7 for driving the track 2, and the motor 7 is connected to the drive wheel of the track 2 via a transmission.

[0042] The electronic balance 3 is set close to the conveying surface of the track 2, and the detection area of ​​the electronic balance 3 corresponds to the graphite column conveying path of the track 2. The electronic balance 3 is electrically connected to the external control system, which can transmit the weight detection data to the control system, and the control system controls the grasping action of the first robotic arm 5.

[0043] The infrared height limiting device 4 is horizontally fixed to the top surface of the track 2, and the detection end of the infrared height limiting device 4 is vertically facing the conveying surface of the track 2. The infrared height limiting device 4 is electrically connected to the external control system, and can transmit the height detection data to the control system. The control system controls the grasping action of the second robotic arm 6, and the detection height of the infrared height limiting device 4 can be adjusted according to the qualified height threshold of the graphite column.

[0044] Both the first robotic arm 5 and the second robotic arm 6 are fixedly connected to the outside of the track 2 via a fixed base, and the gripping ends of both are located directly above the track 2. The gripping range of the first robotic arm 5 covers the detection position of the track 2 corresponding to the electronic balance 3, thereby ensuring that the first robotic arm 5 can accurately grip graphite columns that do not meet the weight requirements, avoiding missed or incorrect gripping. The gripping range of the second robotic arm 6 covers the detection position of the track 2 corresponding to the infrared height limiting device 4, thereby ensuring that the second robotic arm 6 can promptly grip graphite columns that do not meet the height requirements, preventing unqualified products from entering subsequent stages with the track 2.

[0045] Using the above structure, the graphite column, after being pressed into shape by the repress, is conveyed from the output end of the repress along the guide assembly 9 and the unloading assembly 8 to the input end of the track 2. Simultaneously, the drive system of the track 2 is activated, causing the track 2 to stably convey the graphite column at a preset speed. When the graphite column is conveyed by the track 2 to the corresponding detection position of the electronic balance 3, the electronic balance 3 performs weight detection on the graphite column and provides real-time feedback of the detection data. If the detection result shows that the weight of the graphite column is unqualified, the control system triggers the action of the first robotic arm 5 at the corresponding position. The first robotic arm 5 grabs and removes the graphite column. Graphite pillars that do not meet weight requirements; if the weight test is qualified, the graphite pillar continues to be conveyed to the next testing stage with the track 2; when the graphite pillar with qualified weight is conveyed to the corresponding detection position of the infrared height limiting device 4 via the track 2, the horizontally placed infrared height limiting device 4 performs height detection on the graphite pillar to determine whether its height meets the qualified standard. If the detection result is that the height is unqualified, the control system triggers the second robotic arm 6 at the corresponding position to move. The second robotic arm 6 grabs and removes the graphite pillar with unqualified height; if the height detection is qualified, the graphite pillar continues to be conveyed with the track 2.

[0046] Specifically, during the feeding process of the four-column hydraulic press onto the track 2, the graphite columns enter the inner side of the track 901 of the guide assembly 9 from the four-column hydraulic press. Multiple graphite columns are guided by the converging part 905a of the two sets of support plates 905 to roll and adhere closely along the track 901 towards the side plate 802. Rotating the knob 906b drives the screw 906 to rotate, and the two sets of oppositely rotating external threads 906a drive the two sets of support plates 905 to slide in opposite directions, thereby adjusting the distance between the two sets of support plates 905 to match the length of the corresponding graphite columns. This ensures that the rolling channel formed between the two sets of support plates 905 can guide the graphite columns to roll smoothly downwards along the slope, arranging them parallel and closely along the track 901 near one end of the hopper 801, forming a row of graphite columns awaiting inspection. When it is necessary to place the graphite columns one by one onto the track 2 for inspection, the lifting push rod 9... 03. Push the top side movable plate 902 upward to push the lowest graphite column upward along the side plate 802 to the feed inlet 801a through the support plate 902a. At the same time, the baffle plate 902b blocks the adjacent graphite column, thereby ensuring that only one graphite column is pushed into the hopper 801 at a time. The graphite column that falls into the hopper 801 through the feed inlet 801a is blocked by the limiting column 804, thereby adjusting the graphite column from a parallel state to an inclined state during the falling process. At this time, the graphite column can rotate and roll along the inner wall of the hopper 801 and fall vertically into the balance tube 803 to adjust the graphite column from a horizontal state to a vertical state. At the same time, it falls onto the top surface of the track 2 to keep the graphite column upright on the track 2 and follow the track 2 to leave the balance tube 803 through the discharge hole 803a, realizing the process of discharging a single graphite column onto the track 2.

[0047] After one graphite column is fed, the lifting push rod 903 drives the movable plate 902 to move down as a whole until the support plate 902a moves down to be flush with the top surface of the receiving groove 901a. At this time, the blocking effect of the baffle plate 902b on the next graphite column disappears, so that the next graphite column can be guided by gravity to roll to the top side of the support plate 902a, in preparation for the next feeding action of the graphite column into the hopper 801.

[0048] By setting up a crawler 2, an electronic balance 3, an infrared height limit device 4 and a robotic arm, the entire process of graphite column output from the re-pressing machine, detection and picking out of defective products is automated. No manual handling, manual measurement and sorting are required, reducing manpower input and adapting to the high-efficiency operation requirements of industrial production.

[0049] The feeding assembly 8, in conjunction with the lifting push rod 903, support plate 902a and baffle plate 902b of the guide assembly 9, enables the feeding of individual graphite columns one by one. With the help of the hopper 801, balance tube 803 and limit post 804, the graphite column is adjusted from a horizontal state to a vertical state and stands upright on the track 2, so as to avoid the graphite column shifting or tipping over during the feeding process and affecting the test results.

[0050] In addition, adjustable support plates 905 are set as constraint components to guide the graphite columns to roll one by one and arrange them in the track 901. They can be used for graphite columns of different lengths, increasing the versatility of the equipment, ensuring the continuous transport of graphite column products to be inspected on the track 2, and ensuring inspection efficiency.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
