Description

Technical Field

[0001] This invention relates to the field of automated production of bars, and specifically to an automated production equipment for bar grinding. Background Technology

[0002] The existing bar production process is very complex, and each process requires transfer and manual processing. For example, the raw materials for existing bars are supplied in batches and piled up in a mess. When there are color differences or differences in material or shape between the two ends of the bars, manual screening and reversal are required, which makes it impossible to achieve automated online production of an automated production line.

[0003] In addition, the existing bar processing requires a lot of processing equipment, and each piece of equipment requires manual intervention, making it difficult to meet the needs of mass production. Often, products processed in the same batch have different qualities. More importantly, the processing efficiency is extremely low, and the fatigue of personnel is high. Bars made of special materials can also easily irritate and damage the skin.

[0004] In summary, existing bar processing methods need further improvement to meet the needs of mass production. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide an automated production equipment for bar grinding, which is simple in structure, easy to manufacture, easy to implement and low in cost, solving the problems of cumbersome processes, low efficiency, high defect rate and difficulty in meeting the needs of mass production in existing bar grinding processes.

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

[0007] An automated production equipment for grinding bars, the equipment comprising:

[0008] The feed hopper holds the bar stock and transfers it to the first grinding machine for grinding.

[0009] The first grinding machine is used to grind the surface of bars;

[0010] A cleaning and conveying assembly is connected to the first grinding machine and is used to transfer the ground bars and clean the dust.

[0011] The detection component includes a conveyor, an image acquisition unit, and a control unit. The conveyor receives the cleaned and dried bar material and moves it to the image acquisition unit to acquire images. The control unit analyzes and stores the characteristics of the bar material based on the acquired images.

[0012] The reversing assembly is suspended above the conveyor table and uses a vacuum adsorption component to adsorb the rods and rotate them to arrange them in a uniform direction.

[0013] The unloading assembly is used to grab and transfer the bar stock after the conveyor table is reversed to the second grinding machine to grind the end of the bar stock, or to guide it into the defective material bin along the end of the conveyor table.

[0014] Furthermore, the production equipment also includes a storage assembly disposed between the cleaning and conveying assembly and the detection assembly to buffer the bars; the storage assembly includes a first frame, a first motor, a first transmission belt, and a top-stopping component; the first motor drives the first transmission belt, which is wound in a ring around the first frame, to move, and the direction of movement of the first transmission belt is perpendicular to the direction of movement of the bars on the cleaning and conveying assembly; a feed inlet is provided on the side of the first frame, and the top-stopping component is installed on the other side opposite to the feed inlet; wherein, a plurality of placement positions for the bars to enter are arranged parallel and spaced apart on the first transmission belt, and each placement position is displaced as the first transmission belt moves, so that the axis of the placement position coincides with or is parallel to the axis of the bars at the feed inlet, and moves along the axial direction of the placement position until it is held against the top-stopping component.

[0015] Furthermore, the storage assembly also includes a position detection structure for aligning the placement position on the first transmission belt with the bar at the inlet. The position detection structure includes an alignment block and a sensor. The alignment block is mounted on the first frame and is used to place the sensor so that the sensor is suspended above the first transmission belt. After the bar abuts against the abutment placement device, the first motor drives the first transmission belt to rotate a certain distance so that the other placement position corresponds to the inlet, and the sensor synchronously aligns and senses the other placement position.

[0016] Furthermore, the cleaning and conveying assembly includes a second frame, a second transmission belt, and a rinsing assembly and a blowing assembly suspended on the second transmission belt. The second transmission belt drives the bars to enter the rinsing assembly and the blowing assembly in a head-to-tail arrangement for corresponding rinsing and drying.

[0017] Furthermore, the rinsing assembly includes a rinsing component suspended above the second transmission belt and a liquid receiving tray; the liquid receiving tray is fixed to the second frame, and the second transmission belt is installed therein; the rinsing component is arranged perpendicular to the horizontal direction, and the water spraying direction is offset by a certain distance relative to the axis of the bar.

[0018] Furthermore, the blowing assembly is used to blow away residual water on the rod and the second transmission belt; the blowing assembly includes an air outlet and an air inlet connected to each other, the air outlet extends horizontally and the blowing direction is set at an angle to the horizontal plane.

[0019] Furthermore, the detection component includes at least two sets of image acquisition units, and the two sets of image acquisition units are respectively set to correspond to the axial and radial directions of the bar.

[0020] Furthermore, the reversing assembly includes a rotary motor and a lifting structure. The rotary motor is suspended above the conveyor table via a column and is electrically connected to the control unit, and is used to drive the vacuum adsorption component to rotate. The lifting structure is located below the conveyor table and includes a connected lifting cylinder and a push block. The push block has U-shaped grooves on both sides that are adapted to the rod. The lifting cylinder drives the push block to move upward so that the U-shaped grooves of the push block are adapted to the positions of the two ends of the rod, and lifts the rod upward for the vacuum adsorption component to adsorb.

[0021] Furthermore, the unloading assembly includes a displacement structure and a bidirectional transport structure. The displacement structure is used to drive the bidirectional transport structure to translate. The bidirectional transport structure is used to drive the gripper to move in a direction perpendicular to the conveyor table and transfer the bar to the end face grinder.

[0022] Furthermore, the bidirectional transport structure includes a base plate, a drive unit, two rollers, an annular toothed belt, and two sets of gripping components; the base plate has two arc-shaped guide grooves, which are bent outwards and used to guide the arc displacement of the gripping components; the two rollers are fixed on the base plate along the height direction and are connected to the drive unit to prevent rotation; the annular toothed belt is wrapped around the outer circumference of the two rollers and is connected to both sides of the annular toothed belt; wherein, the drive unit drives the rollers to rotate, which in turn drives the annular toothed belt to transport, and causes the two sets of gripping components to move in relative misalignment along the arc-shaped guide grooves.

[0023] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) This invention provides an automated production equipment for bar grinding, which is simple in structure, easy to manufacture, easy to implement, and low in cost. It solves the problems of cumbersome processes, low efficiency, high defect rate, and difficulty in meeting the needs of mass production in existing bar grinding processes. This invention integrates the existing bar processing processes and realizes automated processing. The bar is fed by itself through the hopper, ground by the first grinding machine, and then cleaned by the cleaning and conveying component during the conveying process. This improves the shortcomings of existing manual cleaning, such as uncleanliness, high labor intensity, low efficiency, and easy misplacement. It greatly improves efficiency and accuracy, and facilitates the subsequent detection component to accurately collect, analyze, and store the bar characteristics (which helps to trace defective products). In addition, the reversing component realizes the uniform orientation of the bar. This invention reduces the likelihood of processing errors during end-face grinding, a process impossible with manual screening. Frequent manual screening errors can lead to the high-speed grinding wheel exploding during end-face grinding, potentially injuring others or damaging equipment – ​​a highly dangerous situation. Currently, multiple personnel perform multi-stage inspections to improve directional accuracy, but this method is time-consuming, labor-intensive, and cumbersome. Finally, the feeding assembly transfers good products to a second grinding machine for end-face grinding or to a defective product storage bin. The invention's ingenious structural design and layout, with multiple mechanisms sharing a single conveying mechanism, shortens the transport distance and reduces the time from bar feeding to end-face grinding by at least 10 times, significantly improving efficiency and yield. More importantly, it reduces a large amount of manual intervention.

[0025] (2) The present invention also includes a material storage component, which is used to buffer the bar material and ensure the continuity of the detection feeding. It can also facilitate the subsequent batch transportation to the detection component for transmission, avoiding the risk of machine stoppage during detection and the bar material being unable to enter, resulting in stacking, squeezing and damage.

[0026] (3) The present invention achieves conveying, rinsing and drying in sequence through the cleaning and conveying component, and realizes the action of each process without stopping the machine, improving efficiency and surpassing the effect of manual dust cleaning; moreover, the rod can be driven to rotate during rinsing and drying, realizing all-round cleaning and drying, which facilitates accurate subsequent detection.

[0027] (4) The present invention sets up two sets of image acquisition units and performs detection relative to the axial and radial directions of the bar. It can realize end face detection and size detection, and can also identify whether the orientation is incorrect and needs to be changed. Compared with manual selection, it is more accurate and has higher precision. The bar with an error setting value of 0.05mm can be set as a defective product and recycled to the defective product bin at the end of the conveyor of the detection component.

[0028] (5) The feeding component of the present invention includes a displacement structure and a bidirectional transport structure. The displacement structure is used to drive the product to translate on the X and Y axes on the horizontal plane, while the bidirectional transport structure realizes the Z-axis displacement. The bidirectional transport structure can be used to improve the height difference between the conveyor table and the centerless grinder. Through the action of the double arc guide rail, interference between the two is avoided during operation. While improving efficiency, it solves the problem that the height difference is difficult to transport or that a new transmission mechanism needs to be added. The whole structure is ingeniously designed and has a small size and small footprint. Attached Figure Description

[0045] See Figure 1-10 The present invention discloses an automated production equipment for bar grinding, which is mainly used for automated processing of bar A, including surface grinding, cleaning of grinding dust, drying, conveying and detection, reversing, etc., and finally sending it to the end face grinding machine to grind the end face of bar A.

[0046] The production equipment includes:

[0047] The feed hopper 1 is used to hold the bar A and transfer it to the first grinding machine 2 for grinding. It should be noted that the feed hopper 1 described in this invention is exemplified by the vibratory plate 1. The bar A is placed in the vibratory plate 1 and guided into the first grinding machine 2 through the inclined surface for grinding.

[0048] The first grinding machine 2 is used to grind the surface of the bar A. Here, the first grinding machine 2 is exemplified by a centerless grinding machine. It grinds the outer peripheral surface of the bar A to achieve the required dimensions. Since it is a grinding machine, its surface accuracy and coaxiality are high. Moreover, the present invention uses two centerless grinding machines for fine grinding.

[0049] Cleaning conveyor assembly 3, see Figure 2 , 3 It is connected to the first grinding machine 2 and is used to transfer the ground bar A and clean the dust;

[0050] The cleaning and conveying assembly 3 includes a second frame 31, a second transmission belt 32, and a rinsing assembly 33 and a blowing assembly 34 suspended on the second transmission belt 32. The second transmission belt 32 drives the bar A, arranged end to end, into the rinsing assembly 33 and the blowing assembly 34 for corresponding rinsing and drying. It should be noted that the second transmission belt 32 is driven by components such as a motor 321, a transmission wheel 322, and a tension wheel 323, so that the bar A can move along its axial direction. During the movement, when passing through the rinsing assembly 331, the dust on the outer surface and ends of the bar A, as well as the grinding fluid or coolant added during the grinding process, are rinsed off. Then, it enters the blowing assembly 34 for drying, blowing the rinsing water away from the bar and drying the second transmission belt 32. Specifically, as follows:

[0051] The rinsing assembly 33 includes a rinsing component 331 suspended above the second transmission belt 32 and a liquid receiving tray 332; the liquid receiving tray 332 is fixed to the second frame 31, and the second transmission belt 32 is installed therein; the rinsing component 331 is arranged perpendicular to the horizontal direction, and the water spraying direction is offset by a certain distance relative to the axis of the bar A, so that the bar A rotates during the transportation process to clean the entire bar A;

[0052] The blower assembly 34 is used to blow away residual water on the rod A and the second transmission belt 32. The blower assembly 34 includes an air outlet 341 and an air inlet 342 connected to each other. The air outlet 341 extends horizontally and the blowing direction is set at an angle with the horizontal plane, so as to better dry the rod A and the second transmission belt 32. In order to improve the blowing and drying effect, the air inlet 342 of the present invention introduces hot air.

[0053] The production equipment also includes a storage assembly 4 (see...) Figure 4 , 5The storage assembly 4 is located between the cleaning and conveying assembly 3 and the detection assembly to buffer the bar A. The storage assembly 4 includes a first frame 41, a first motor 42, a first transmission belt 43, and a top-stopping member 45. The first motor 42 drives the first transmission belt 43, which is wound around the first frame 41, to move. The direction of movement of the first transmission belt 43 is perpendicular to the direction of movement of the bar A on the cleaning and conveying assembly 3. The first frame 41 has an inlet 411 on its side, and the top-stopping member 45 is installed on the other side opposite to the inlet 411. The first transmission belt 43 has a plurality of parallel and spaced placement positions 430 for the bar A to enter. Each placement position 430 moves with the movement of the first transmission belt 43 so that the axis of the placement position 430 coincides with or is parallel to the axis of the bar A at the inlet 411 and moves along the axial direction of the placement position 430 until it is held against the top-stopping member 45.

[0054] Detection component 5, (see Figure 4 , 6 -8) It includes a conveyor 51, an image acquisition unit 52, and a control unit (not shown in the figure); the conveyor 51 receives the cleaned and dried bar A and moves it to the image acquisition unit 52 to acquire an image (the image acquisition unit 52 is illustrated by the Keyence 2D projection inspection device); the control unit (not shown in the figure) analyzes and stores the features of the bar A based on the acquired image; the features of the bar A include the shape features, size features, color difference, material, etc. of the end face of the bar A; the inspection component 5 includes at least two sets of image acquisition units 52, and the two sets of image acquisition units 52 are respectively set to the axial and radial directions of the bar A, so that data can be acquired better, the comparison is more accurate, and the quality of good products can be guaranteed;

[0055] The reversing component 6 is suspended above the conveyor platform 51 of the detection component 5. After the rod A is adsorbed by the vacuum adsorption component 61, it is rotated and adjusted to be arranged in a uniform direction. It should be noted that in this invention, the reversing component 6 includes a rotary motor 62 and a lifting structure 63. The rotary motor 62 is suspended above the conveyor platform 51 by a column and is electrically connected to the control unit. It is used to drive the vacuum adsorption component 61 to rotate. The lifting structure 63 is located below the conveyor platform 51 and includes a connected lifting cylinder 631 and a push block 632. The push block 632 has U-shaped grooves on both sides that are adapted to the rod A. The lifting cylinder 631 drives the push block 632 to move upward so that the U-shaped grooves of the push block 632 are adapted to the positions of the two ends of the rod A and lift the rod upward so that it can be adsorbed by the vacuum adsorption component 61.

[0056] Material feeding assembly 7 (see Figure 9 , 10The feeding assembly 7 is used to grab and transfer the bar A after the conveyor table 51 is reversed to the second grinding machine 8 for grinding the end of the bar A, or to guide it into the defective material bin along the end of the conveyor table 51; wherein, the feeding assembly 7 includes a displacement structure 71 and a bidirectional transport structure 72, the displacement structure 71 is used to drive the bidirectional transport structure 72 to translate; the bidirectional transport structure 72 is used to drive the gripper to move in a direction perpendicular to the conveyor table 51 and transfer the bar A to the end face grinding machine.

[0057] More specifically, the storage assembly 4 further includes a position detection structure 44, which is used to drive the placement position 430 on the first transmission belt 43 to align with the bar A at the inlet 411. The position detection structure 44 includes an alignment block 441 and a sensor 442. The alignment block 441 is mounted on the first frame 41 and provides a place for the sensor 442, so that the sensor 442 is suspended above the first transmission belt 43. After the bar A abuts against the abutment member 45, the first motor 42 drives the first transmission belt 43 to rotate a certain distance, so that the other placement position 430 corresponds to the inlet 411, and the sensor 442 simultaneously aligns and senses the other placement position 430. Through this position detection structure 44, it is ensured that each bar A can be accurately aligned when entering the placement position 430, minimizing deviation. Simultaneously, the vacuum adsorption member 61 can align the adsorption of the bar A, minimizing deviation.

[0058] More specifically, the bidirectional transport structure 72 includes a base plate 721, a drive member 722, two rollers 723, an annular toothed belt 724, and two sets of gripping members 725. Two arc-shaped guide grooves 721A are formed on the base plate 721, and these two arc-shaped guide grooves 721A are bent outwards to guide the arc-shaped displacement of the gripping members 725. The two rollers 723 are fixed to the base plate 721 along the height direction and are connected to the drive member 722 to prevent rotation. The annular toothed belt 724 is wound around the outer periphery of the two rollers 723 and connected to both sides of the annular toothed belt 724. The drive member 722 drives the rollers 723 to rotate, which in turn moves the annular toothed belt 724, causing the two sets of gripping members 725 to move in a relatively staggered manner along the arc-shaped guide grooves 721A.

[0059] For detailed implementation methods, please refer to Figure 1-10The automated production equipment for grinding bar A according to the present invention mainly includes the following components: bar A, feed hopper 1, first grinding machine 2, cleaning and conveying assembly 3, second frame 31, second transmission belt 32, rinsing assembly 33, blowing assembly 34, motor 321, transmission wheel 322, tension wheel 323, rinsing component 331, liquid receiving tray 332, air outlet duct 341, air inlet 342, material storage assembly 4, first frame 41, feed inlet 411, first motor 42, first transmission belt 43, and placement position 43. 0. Top-stop positioning component 45. Position detection structure 44. Alignment block 441. Sensing component 442. Top-stop positioning component 45. Detection assembly 5. Conveyor 51. Image acquisition unit 52. Control unit (not shown in the figure). Reversing assembly 6. Vacuum adsorption component 61. Rotary motor 62. Lifting structure 63. Lifting cylinder 631. Push block 632. Unloading assembly 7. Displacement structure 71. Bidirectional transport structure 72. Base plate 721. Drive component 722. Two rollers 723. Annular toothed belt 724. Two sets of gripping components 725.

[0060] In actual assembly and use,

[0061] (1) Feed hopper 1, which uses a vibrating plate as feed hopper 1, and the bar A arranged in sequence after vibration is moved to the first grinding machine 2 (centerless grinding machine) through the inclined material channel. The bar A is ground by the size and method set by the user. After grinding the outer peripheral surface of the bar A, it enters another centerless grinding machine for fine grinding.

[0062] (2) Assemble the cleaning and conveying assembly 3. After fixing the second frame 31 in position, cover the second transmission belt 32 on the two transmission wheels 322. Drive one of the transmission wheels 322 to rotate by the motor 321 on the side to prevent rotation. In this way, the bar A is moved along the upper surface of the second transmission belt 32. The rinsing assembly 33 and the blowing assembly 34 are respectively suspended above the second transmission belt 32.

[0063] Specifically, the rinsing component 331 is suspended above the second transmission belt 32, and the liquid receiving tray 332 is fixed to the second frame 31, which houses the second transmission belt 32. The rinsing component 331 is arranged perpendicular to the horizontal direction, and the water spray direction is offset by a certain distance relative to the axis of the rod A. This arrangement allows the rod to rotate during transportation, cleaning the entire rod A. The cleaned dust and cleaning water are collected in the liquid receiving tray 332 and discharged from the drain port of the liquid receiving tray 332.

[0064] The blowing assembly 34 includes an air outlet 341 and an air inlet 342 connected to each other. The air outlet 341 extends horizontally and the blowing direction is set at an angle with the horizontal plane, so as to better dry the bar A and the second transmission belt 32. In order to improve the blowing and drying effect, the air inlet 342 of the present invention introduces hot air.

[0065] (3) Assemble the storage assembly 4. After placing the first frame 41, the first motor 42 drives the first transmission belt 43 to move. Its operation mode is the same as that of the second transmission belt 32 in the cleaning and conveying assembly 3. However, the first transmission belt 43 has several placement positions 430 (the placement position 430 refers to the groove for placing the bar A) arranged at intervals along the vertical movement direction. On both sides of the first frame 41, there are also inlet ports 411 and top abutment members 45 arranged opposite to the inlet ports 411. The inlet ports 411 supply the bar A to the cleaning and conveying assembly. After component 3 enters the placement position 430 on the first transmission belt 43 through the opening, and is pushed against the position sensing of the top abutment member 45; in addition, the present invention also provides a position detection structure 44 to detect whether the placement position 430 is aligned with the feed inlet 411; by setting an alignment block 441 above the corresponding placement position 430, and setting a sensing element 442 (the sensing element 442 can be a distance sensor, etc.) on the alignment block 441, the accuracy is improved by sensing the placement position 430, and the entire device fails due to misalignment;

[0066] (4) Install detection component 5 and reversing component 6. The detection component 5 includes a conveyor 51, at least two sets of image acquisition units 52 and a control unit (not shown in the figure). The conveyor 51 is also provided with grooves for the parallel arrangement of rods A. One set of image acquisition units 52 is set in the axial direction of rods A to acquire the end face and shape features of rods A. The other set of image acquisition units 52 is set in the radial direction of rods A to acquire the external dimensions of rods A and feed them back to the control unit (not shown in the figure). After comparing, analyzing and storing each feature, it is determined whether reversing is required, whether the materials are the same, and whether the dimensions are in accordance with the requirements.

[0067] Subsequently, a lifting structure 63 and a rotary motor 62 and a vacuum adsorption component 61 are installed below the conveyor platform 51. The rotary motor 321 is suspended above the conveyor platform 51 by a column, and the rotary motor 62 is connected to the vacuum adsorption component 61 to drive the vacuum adsorption component 61 to rotate 180°. The lifting structure 63 includes a lifting cylinder 631 and a push block 632. The push block 632 has U-shaped grooves on both sides that are adapted to the rod A. The lifting cylinder 631 drives the push block 632 to move upward so that the U-shaped grooves of the push block 632 are adapted to the positions of the two ends of the rod A, and the rod A is lifted upward for the vacuum adsorption component 61 to adsorb.

[0068] (5) Assemble the unloading assembly 7, which is used to transfer the bar A from the conveyor table 51 to the second grinding machine 8 (here, the second grinding machine 8 refers to the end face grinding machine); during installation, the displacement structure 71 is mounted on the frame, and the bidirectional transport structure 72 is mounted on the displacement structure 71. Here, the displacement structure 71 is a displacement structure 71 that moves along the X and Y axes, while the bidirectional transport structure 72 is used to drive the bar A to move along the Z axis; the front side of the substrate 721 is equipped with two Rollers 723 are arranged along the height direction. A drive unit 722 is then passed from the back of the substrate 721 to the front and is connected to one of the rollers 723 to prevent rotation, thereby driving the roller 723 to rotate. Here, the drive unit 722 is exemplified by a servo motor 321. Then, an annular toothed belt 724 is wound around the two rollers 723, and two sets of gripping members 725 are respectively installed on the two arc-shaped guide grooves 721A on the substrate 721 and on both sides of the annular toothed belt 724.

[0069] Finally, after installing the defective product bin at the end of the conveyor 51, the assembly of the entire equipment is completed.

[0070] When using,

[0071] (1) A batch of bars A are arranged end to end by a vibratory plate and then enter the first grinding machine 2 for grinding. After the surface reaches the required size, they continue to move forward.

[0072] (2) Then the bar A moves onto the second transmission belt 32 and stops at the rinsing assembly 33. The dust and grinding fluid on its surface are cleaned by the rinsing component 331. It should be noted that the rinsing direction of the rinsing component 331 is offset from the axis of the bar A. So the bar A can be rotated during the rinsing process, which can better clean the dust. Of course, even if it does not rotate, it can be cleaned by a large amount of rinsing water. The wastewater flows down into the liquid receiving plate 332 for subsequent water filtration and circulation. Then it moves to the blowing assembly 34. Similarly, hot air is blown out from the air outlet 341 to clean the residue on the surface of the bar A. The first transmission belt 43 is also dried by the blowing.

[0073] (3) The cleaned bar A then enters the feed port 411 of the storage component 4 and enters the placement position 430 of the first transmission belt 43 from the feed port 411. It is pushed to the top stop member 45. After the top stop member 45 senses the bar A, it starts the first motor 42 to drive the first transmission belt 43 to move one position so that the other empty placement position 430 corresponds to the feed port 411. At this time, the position detection structure 44 is also activated. After the detection member senses the placement position 430 on the other side, it is corrected to ensure that the subsequent feed port 411 corresponds to the empty placement position 430, so as to avoid stagnation and machine stoppage.

[0074] (4) Then, the three-axis transfer structure 9 is used to adsorb the bars A on the first transmission belt 43 in batches onto the conveyor table 51 on the detection component 5, and then the conveyor table 51 is moved. During the movement, the two sets of image acquisition units 52 capture various features of the bars A, including shape, material, size, etc., and then the control component is used to determine which bars A need to be reversed. The output command is then given to the reversing component 6 to reverse the direction.

[0075] (5) When it is necessary to change direction, the corresponding lifting cylinder 631 drives the push block 632 to move upward. The push block 632 lifts both ends of the bar A upward and separates it from the conveyor table 51. After it comes into contact with the vacuum adsorption component 61, it is adsorbed and fixed by the vacuum adsorption component 61. Then, it is reset by rotating the rotary motor 62 180°. The vacuum adsorption component 61 breaks the vacuum, and the push block 632 is reset as the lifting cylinder 631 falls. The bar A also falls to its original position.

[0076] (6) If the product is defective after the reversal (e.g., broken bar A), it will fall into the defective product bin along the end of the conveyor 51; if it is good, it will be transferred to the material chamber of the end face grinding machine by the displacement structure 71 and the bidirectional transport structure 72. Specifically, the displacement structure 71 drives the gripper 725 to pick up bar A, the drive component 722 drives the roller 723 to rotate, and the annular toothed belt 724 drives the gripper 725 to move up and down synchronously. The movement directions of the two grippers 725 are parallel and Conversely, when one gripper 725 places the bar A on the end face grinder (at a high position), the other gripper 725 is at a low position to grip the bar A on the conveyor table 51. This repeated movement not only improves efficiency but also enhances stability. It should be noted that, in order to prevent interference between the two grippers 725 during their movement and to improve stability, the substrate 721 is provided with an arc-shaped guide groove 721A for the two grippers 725 to avoid each other, thereby ensuring that their mutual movement will not cause interference.

[0077] The bar A is then conveyed and displaced in this sequence to complete the automated processing.

[0078] This invention provides an automated production equipment for bar grinding, which is simple in structure, easy to manufacture, easy to implement, and low in cost. It solves the problems of cumbersome processes, low efficiency, high defect rates, and difficulty in meeting the needs of mass production in existing bar grinding processes. This invention integrates and automates existing bar processing procedures. The bar is automatically fed through a hopper, ground by a first grinding machine, and then cleaned during transport by a cleaning and conveying assembly. This overcomes the drawbacks of manual cleaning, such as uncleanliness, high labor intensity, low efficiency, and easy misplacement, significantly improving efficiency and accuracy. It also facilitates accurate collection, analysis, and data storage of bar characteristics by subsequent inspection components (helping to trace defective products). Furthermore, a reversing assembly ensures uniform orientation of the bars. Subsequent end-face grinding is less prone to processing errors, which is impossible with manual screening. Manual screening often results in errors, leading to the high-speed grinding wheel exploding during end-face grinding. These ejected particles can easily injure others or damage other equipment, posing a high risk. Currently, multiple personnel perform multi-stage inspections to improve directional accuracy, but this method is time-consuming, labor-intensive, and cumbersome. Finally, the feeding assembly transfers good products to a second grinding machine for end-face grinding or to a defective product storage bin. This invention features a clever structural design and layout, with multiple mechanisms sharing a single conveyor, shortening the transport distance and reducing the time from bar feeding to end-face grinding by at least 10 times, significantly improving efficiency and yield. More importantly, it reduces a large amount of manual intervention. The invention also includes a storage component, which buffers the bars and ensures the continuity of the feeding process. It also facilitates subsequent batch transport to the testing component, preventing downtime during testing and the risk of bars being stacked or damaged due to inability to enter. The invention achieves sequential conveying, rinsing, and drying through a cleaning and conveying component, performing each process without stopping the machine, improving efficiency and surpassing the effect of manual dust cleaning. Furthermore, the washing and drying processes drive the bars to rotate, achieving comprehensive cleaning and drying for accurate subsequent testing. The invention features two sets of image acquisition units that detect the bars axially and radially, enabling end-face and dimensional detection as well as orientation identification. If the placement is incorrect, it needs to be reversed. Compared with manual selection, it is more accurate and precise. A bar with an error setting of 0.05mm can be set as a defective product and recycled to the defective product bin at the end of the conveyor of the detection component. The feeding component of this invention includes a displacement structure and a bidirectional transport structure. The displacement structure is used to drive the product to translate on the X and Y axes on the horizontal plane, while the bidirectional transport structure realizes the Z-axis displacement. The bidirectional transport structure can also be used to improve the height difference between the conveyor and the centerless grinder. Through the action of the double arc guide rail, interference between the two is avoided during operation. While improving efficiency, it solves the problem of difficulty in transporting products with height differences or the need to add new transmission mechanisms. The whole structure is ingeniously designed and has a small size and small footprint.

[0079] The description of the above specification and embodiments is used to explain the scope of protection of the present invention, but does not constitute a limitation on the scope of protection of the present invention.
