Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a workpiece changing system for a double-end face grinder. Background Technology

[0002] Double-end grinding machines, as highly efficient surface machining equipment, have the core advantage of simultaneously and precisely grinding two parallel end faces of a workpiece, significantly improving machining efficiency. However, in actual machining processes, a critical step commonly exists – workpiece changing operation. Specifically, workpieces (such as carbide cutting tools) are usually pre-loaded into a turnover tray (with multiple workpiece accommodating cavities arranged in a rectangular array) for easy transfer and storage. Before machining, the workpiece needs to be transferred from the turnover tray to the grinding machine's dedicated machining tray (usually composed of a base plate and a positioning plate with multiple through holes, which, when fitted together, form a positioning cavity with one end closed). After grinding is completed, the workpiece needs to be moved back from the machining tray to the turnover tray for subsequent processes or storage.

[0003] In the existing technology, this disc-changing operation mainly faces the following challenges: 1. Manual Operation Dominance: Currently, the mainstream implementation method still heavily relies on manual labor. Operators need to repeatedly pick up and place workpieces manually, resulting in extremely high labor intensity, a relatively harsh working environment (accompanied by noise and dust), and low production efficiency, making it difficult to meet the needs of large-scale, continuous production.

[0004] 2. Low level of automation and efficiency bottleneck: Although some solutions attempt to use robotic arms to automate tray changing, their working mode is usually to pick up and place workpieces one by one. While this method reduces the workload of manpower to some extent, the improvement in efficiency is limited in essence.

[0005] 3. Long cycle time: The robotic arm operates one by one, which consumes a lot of cycle time, becoming a bottleneck that restricts the overall production cycle time and cannot fully utilize the high-efficiency grinding capability of the double-end face grinder itself.

[0006] 4. Complex control and high cost: Achieving precise and reliable workpiece picking and placing between the turntable and the processing tray by a robotic arm requires complex motion trajectory planning, precise positioning control, and a reliable collision avoidance detection system. This not only increases the technical difficulty and cost of system implementation but also raises the complexity of debugging and maintenance.

[0007] 5. Low system integration and poor flexibility: Such solutions often require the design of complex positioning fixtures and coordination control systems for robotic arms, turntables, and processing trays, resulting in low system integration. When the workpiece type or size changes, a significant amount of time is required to reprogram and adjust the fixtures, leading to poor adaptability (flexibility). Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a workpiece changing system for a double-end face grinder that can improve production efficiency, is easy to control, has low implementation cost and difficulty of implementation, and is easy to debug and maintain.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A workpiece changing system for a double-end face grinder includes a carrying device for carrying the processing tray, a feeding device for conveying workpieces, an unloading device for unloading workpieces one by one from the processing tray onto the feeding device, and a shifting device for driving the turnover tray to move.

[0014] The feeding device is provided with a flared guide groove for docking with the receiving groove to guide the workpiece into the receiving groove.

[0015] The transfer device includes a placement platform for placing a turntable and a transfer drive assembly for driving the placement platform to move. The direction in which the transfer drive assembly drives the placement platform to move is consistent with the extension direction of each receiving groove.

[0016] The supporting device includes a rotating assembly for supporting the processing disk and driving the processing disk to rotate. The feeding device is located below the processing disk on the rotating assembly. The unloading device includes a movable seat and a friction ring belt mounted on the movable seat and driven by a second belt drive mechanism. The friction ring belt has a friction transmission section. The friction transmission section is used to enter the space above the processing disk to block the workpiece rotating with the processing disk and drive the workpiece to fall from the edge of the processing disk onto the feeding device. The unloading device also includes a moving drive assembly for driving the movable seat to move so that the friction transmission section enters and exits the space above the processing disk and adjusting the blocking position of the friction transmission section.

[0017] The friction transmission section is provided with a guide member at its end. The guide member has a guide surface for first contacting the workpiece on the processing plate and guiding the workpiece to move towards the friction transmission section. The angle between the guide surface and the friction transmission section is an obtuse angle.

[0018] The guide is installed in an adjustable manner, and the angle between the guide surface and the friction transmission section can be changed by adjusting the angle.

[0019] The friction ring belt is mounted on the movable seat in a manner that allows for adjustable mounting angles, and the direction in which the friction transmission section enters the space above the processing disk can be changed by adjusting the mounting angle.

[0020] The bearing device is equipped with multiple rotating components, which are mounted on a rotating seat driven by a rotary drive mechanism. The rotating seat can move each rotating component to the unloading device to cooperate with the unloading device to unload the workpiece.

[0021] The rotating assembly includes a mounting base, a turntable rotatably mounted on the mounting base, and a rotating drive component connected to the turntable and driving the turntable to rotate.

[0022] The feeding device is a belt conveyor, and the conveying surface of the belt conveyor is provided with side baffles on both sides to prevent the workpiece from falling.

[0023] The transfer device is connected to an empty tray supply device for supplying empty turntables to the transfer device and a palletizing device for receiving and stacking turntables filled with workpieces.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1: like Figure 1 and Figure 2 As shown, the workpiece changing system for a double-end face grinder in this embodiment includes a carrying device 1 for carrying the processing tray 100, a feeding device 2 for conveying workpieces, an unloading device 3 for unloading workpieces one by one from the processing tray 100 onto the feeding device 2, and a transfer device 4 for driving the turnover tray 200 to move. The feeding device 2 is connected to a loading device 5 for arranging the workpieces output by the feeding device 2 into rows and loading them into the turnover tray 200 of the transfer device 4. This workpiece changing system for a double-end face grinder employs a combination of a feeding device 2, an unloading device 3, a transfer device 4, and a loading device 5. During operation, the unloading device 3 unloads workpieces one by one from the processing tray 100 carried by the carrier device 1 onto the feeding device 2. Then, the loading device 5 arranges the workpieces output from the feeding device 2 into rows and loads them into the turntable 200 of the transfer device 4. The transfer device 4 drives the turntable 200 to move, filling it to capacity, thus completing the automatic transfer of workpieces from the processing tray 100 to the turntable 200. Each device has a short operation time for the workpiece, reducing the overall production cycle time of the workpiece changing system and significantly improving production efficiency. Furthermore, each device is easy to control, requiring no complex motion trajectory planning or precise positioning control, resulting in low implementation cost and difficulty, and simple debugging and maintenance.

[0039] In this embodiment, as Figures 3 to 8As shown, the tray loading device 5 includes one or more slot groups 52 and a tray loading drive assembly 51 for driving the movement of the one or more slot groups 52. The slot group 52 is composed of multiple receiving grooves 521 arranged side by side. The tray loading drive assembly 51 is configured to enable each receiving groove 521 to dock with the output end of the feeding device 2 to receive the workpiece. The tray loading device 5 also includes a tray loading assembly 53 for loading the workpiece in the receiving groove 521 into the rotary table 200 of the transfer device 4. When the tray loading device 5 is working, the tray loading drive assembly 51 drives the groove group 52 to move, so that each receiving groove 521 aligns with the output end of the feeding device 2. The workpiece output from the output end of the feeding device 2 enters the receiving groove 521. After entering the receiving groove 521, the workpiece stays in the receiving groove 521 under friction. In this way, after all or part of the receiving grooves 521 in the groove group 52 are filled with workpieces, the tray loading assembly 53 loads the workpieces in the receiving grooves 521 together into the turnover tray 200 on the transfer device 4, thus completing the operation of arranging the workpieces into rows and loading them into the turnover tray 200. The tray loading device 5 uses multiple receiving grooves 521 driven by the tray loading drive assembly 51 in conjunction with the tray loading assembly 53. It has the advantages of simple and compact structure, low cost, easy control, and high efficiency while realizing the arrangement of workpieces into rows and loading them into the turnover tray 200. Preferably, each of the above-mentioned receiving grooves 521 is a groove formed by a U-shaped plate, and the openings at both ends allow the workpiece to enter and exit the receiving groove 521.

[0040] In this embodiment, the tray loading drive assembly 51 is further configured to drive the slot assembly 52 to move above the turnover tray 200 driven by the tray transfer device 4. The tray loading assembly 53 includes a pusher drive mechanism 532 and a plurality of pusher members 531 arranged side by side. The pusher drive mechanism 532 is connected to the plurality of pusher members 531 and can drive the plurality of pusher members 531 to extend into the plurality of receiving grooves 521 to push the workpieces from one end of the receiving grooves 521 into the turnover tray 200. When the tray loading drive assembly 51 drives the slot assembly 52 to move above the turnover tray 200 driven by the tray transfer device 4, the pusher drive mechanism 532 drives the plurality of pusher members 531 to extend into the plurality of receiving grooves 521 to push the workpieces from one end of the receiving grooves 521 into the turnover tray 200, so that a row of workpieces can be loaded into a row of workpiece receiving cavities of the turnover tray 200 at the same time. The structure of the tray assembly 53, which cooperates with the receiving groove 521 to load the workpiece, has the advantages of simple and compact structure, low implementation difficulty and cost, and easy control. In this embodiment, the position and number of the multiple receiving grooves 521 correspond one-to-one with the position and number of the single row of workpiece receiving cavities of the turnover tray 200, so that the workpieces in the multiple receiving grooves 521 can fall into the row of workpiece receiving cavities of the turnover tray 200 in a one-to-one correspondence.

[0041] In this embodiment, the transfer device 4 is equipped with multiple guide grooves 54 to guide the workpiece falling from one end of the receiving groove 521 into the turnover tray 200. The position and number of the guide grooves 54 correspond one-to-one with the position and number of the single-row workpiece receiving cavities in the turnover tray 200, ensuring that the workpiece falls accurately and reliably into the corresponding receiving cavity in the turnover tray 200. The guide grooves 54 can also be grooves formed by U-shaped plates, which are arranged inclined downwards from one end of the receiving groove 521 towards the turnover tray 200, so that the workpiece slides smoothly along the receiving groove 521 into the corresponding receiving cavity in the turnover tray 200.

[0042] In this embodiment, the pusher drive mechanism 532 is a mechanism that can drive multiple pusher components 531 to move vertically and horizontally. That is, the pusher drive mechanism 532 drives multiple pusher components 531 to extend into multiple receiving grooves 521 to push the workpiece and to exit the receiving grooves 521 in a vertical and horizontal manner. Its structure is simple, easy to arrange, and easy to control. The pusher drive mechanism 532 can adopt existing technology, such as a combination of a lifting module and a horizontal moving module.

[0043] In this embodiment, the tray loading device 5 is specifically equipped with two sets of independently operating tray loading drive components 51, each of which is connected to at least one set of slots 52. The two tray loading drive components 51 independently drive the slots 52 to move, enabling one tray loading drive component 51 to drive the slots 52 to dock with the feeding device 2 to receive workpieces, while the other tray loading drive component 51 drives the slots 52 to load workpieces into the turnover tray 200 at the tray transfer device 4. This allows the workpiece receiving and workpiece loading into the turnover tray 200 to be performed simultaneously without interference, further improving work efficiency.

[0044] In this embodiment, the tray-loading drive assembly 51 includes an annular belt 511 and a first belt drive mechanism 512 that drives the annular belt 511 to rotate. The slot group 52 is fixed on the annular belt 511. The first belt drive mechanism 512 drives the annular belt 511 to rotate, which can move the slot group 52, thereby enabling each receiving groove 521 to align with the output end of the feeding device 2 to receive workpieces, and enabling the entire slot group 52 to move above the turnover disk 200 driven by the transfer device 4, so that the multiple receiving grooves 521 of the slot group 52 are aligned one by one with the single row of workpiece receiving cavities of the turnover disk 200. This tray-loading drive assembly 51 has the advantages of simple structure, low cost, and easy debugging and control. Specifically, the annular belt 511 has a straight section at one end, and the slot group 52 is located in the straight section when it aligns with the output end of the feeding device 2 and moves above the turnover disk 200 driven by the transfer device 4. The structure of the aforementioned annular belt 511 and the first belt drive mechanism 512 can refer to the prior art, wherein the drive component of the first belt drive mechanism 512 is preferably a stepper motor.

[0045] In this embodiment, the annular belts 511 of the two assembly tray drive assemblies 51 are arranged side by side, and the movement trajectories of the slots 52 connected to the two assembly tray drive assemblies 51 are consistent. In this way, only one fixed assembly tray assembly 53 and one set of operating procedures are needed to unload the workpiece from the slots 52 connected to the two assembly tray drive assemblies 51, which can greatly reduce the control difficulty and simplify the structure, installation and maintenance of the assembly tray assembly 53.

[0046] In this embodiment, the outlet end of the feeding device 2 is provided with a flared guide groove 21 for engaging with the receiving groove 521 to guide the workpiece into the receiving groove 521. The flared guide groove 21 allows the workpiece to be accurately and stably guided into the receiving groove 521, ensuring stable and reliable operation. In other embodiments, the flared guide groove 21 may also be located at the inlet end or the middle of the feeding device 2.

[0047] In this embodiment, the transfer device 4 includes a placement platform 41 for placing the turntable 200 and a transfer drive assembly for driving the placement platform 41 to move. The direction in which the transfer drive assembly drives the placement platform 41 to move is consistent with the extension direction of each receiving groove 521. By driving the placement platform 41 to move along the extension direction of the receiving groove 521, the multiple rows of workpiece receiving cavities of the turntable 200 on the placement platform 41 can be moved row by row to directly below the opening of one end of the receiving groove 521, thereby sequentially loading workpieces into the multiple rows of workpiece receiving cavities of the turntable 200 until the turntable 200 is full. This transfer device 4 has the advantages of simple and compact structure and easy control. The above-mentioned placement platform 41 and transfer drive assembly can refer to the prior art, as long as it can drive the placement platform 41 to move. Preferably, the placement platform 41 is guided by a guide mechanism to improve the smoothness and accuracy of the movement, and the transfer drive assembly can be a telescopic drive component. In another embodiment, the transfer device 4 may also adopt other structural forms, as long as it can move the turntable 200.

[0048] In this embodiment, the supporting device 1 includes a rotating assembly 11 for supporting the processing disk 100 and driving the processing disk 100 to rotate. The feeding device 2 is located on the rotating assembly 11 below the processing disk 100. The unloading device 3 includes a movable seat 31 and a friction ring belt 32 mounted on the movable seat 31 and driven by a second belt drive mechanism 33. The friction ring belt 32 has a friction transmission section 321. The friction transmission section 321 is used to enter the space above the processing disk 100 to block the workpiece rotating with the processing disk 100 and drive the workpiece to fall from the edge of the processing disk 100 onto the feeding device 2. The unloading device 3 also includes a moving drive assembly 34. The moving drive assembly 34 is used to drive the movable seat 31 to move so that the friction transmission section 321 enters and exits the space above the processing disk 100, and to adjust the blocking position of the friction transmission section 321. During operation, the processing disk 100 is placed on the rotating assembly 11. The moving drive assembly 34 drives the moving seat 31 to move, so that the friction transmission section 321 enters the space above the processing disk 100. The position of the friction transmission section 321 is just enough to block the outermost workpiece on the processing disk 100. Then, the rotating assembly 11 drives the processing disk 100 to rotate. The second belt drive mechanism 33 drives the friction ring belt 32 to run. The outermost workpiece on the processing disk 100 (the workpiece furthest from the rotation center of the processing disk 100) will come into contact with the friction transmission section 321 one by one. After the workpiece comes into contact with the friction transmission section 321, under the combined effect of the processing disk 100 rotating with the workpiece and the friction transmission section 321 moving with the workpiece by friction, the workpiece will move along the friction transmission section 321 on the processing disk 100 and fall from the edge of the processing disk 100 onto the feeding device 2. After all the outermost workpieces on the processing disk 100 are unloaded, the moving drive assembly 34 drives the moving seat 31 to move, causing the friction transmission section 321 to move a certain distance towards the center of the processing disk 100. Then, following the aforementioned operation, the next workpiece closer to the rotation center of the processing disk 100 is unloaded. In this manner, all workpieces on the processing disk 100 can be unloaded. This unloading device 3, in conjunction with the rotating assembly 11, can quickly unload workpieces one by one from the processing disk 100 onto the feeding device 2. It has good continuity, high efficiency, simple control, and stable and reliable operation.

[0049] In actual production, workpieces are typically arranged in multiple concentric circles on the processing disc 100 from the inside out, with each circle containing multiple workpieces spaced around the center of the processing disc 100. The unloading device 3 only needs to adjust the blocking position a few times to unload all the workpieces from one processing disc 100.

[0050] In this embodiment, a guide member 35 is provided at the end of the friction transmission section 321. The guide member 35 has a guide surface 351 for first contacting the workpiece on the processing tray 100 and guiding the workpiece to move towards the friction transmission section 321. The angle between the guide surface 351 and the friction transmission section 321 is an obtuse angle. Since the angle between the guide surface 351 and the friction transmission section 321 is an obtuse angle, when the workpiece first contacts the guide surface 351 of the guide member 35, the angle between the workpiece and the guide surface 351 when the workpiece hits the guide surface 351 will be smaller than the angle between the workpiece and the friction transmission section 321 when the workpiece directly hits the friction transmission section 321. This allows the workpiece to hit the friction transmission section 321 at a smaller angle, which can avoid the workpiece's movement trajectory becoming uncontrollable due to excessive rebound caused by an excessively large angle of impact with the friction transmission section 321. This ensures that the workpiece can be stably, reliably, and accurately dropped onto the feeding device 2 by the friction transmission section 321. Especially when the distance between workpieces on the processing disk 100 is small, and the friction transfer section 321 is not allowed to enter the space between two adjacent workpieces at a small angle, the problem caused by the impact angle can be avoided by setting the guide 35. The guide 35 is preferably made of a flat plate, which can not only adapt to smaller workpiece distances, but is also easy to manufacture and has low cost.

[0051] In this embodiment, the guide member 35 is installed in an angle-adjustable manner, and the angle between the guide surface 351 and the friction transmission section 321 can be changed by adjusting the angle. This facilitates adjusting the angle of the guide surface 351 to the optimal value, adapting to different working conditions, and facilitating assembly and debugging. The installation method of the guide member 35 can adopt existing technology. For example, the guide member 35 can be rotatably installed via a swing shaft, which can rotate around the axis of the swing shaft to adjust the angle, and then a locking mechanism such as screws is used to fix the guide member 35 after the angle has been adjusted.

[0052] In this embodiment, the friction ring belt 32 is mounted on the movable base 31 with an adjustable mounting angle, and the direction of the friction transmission section 321 entering the space above the processing disk 100 can be changed by adjusting the mounting angle. This facilitates adjustment of the angle of the friction ring belt 32 for more stable and reliable workpiece movement, and allows for adaptation to workpieces with different structural shapes and placement postures, as well as convenient assembly and debugging. The aforementioned adjustable mounting structure and method of the friction ring belt 32 can be implemented using a manual adjustment mechanism or an automatic adjustment mechanism. Both the manual and automatic adjustment mechanisms can be configured with reference to existing conventional technologies. For example, the friction ring belt 32 is mounted on a bracket. The manual adjustment mechanism uses an arc-shaped groove on the bracket, and screws pass through the arc-shaped groove to connect the bracket to the movable base 31. The automatic adjustment mechanism uses a motor to drive the bracket to rotate on the movable base 31 to adjust the angle.

[0053] In this embodiment, as Figure 9 and Figure 10As shown, the bearing device 1 is equipped with multiple rotating components 11, which are mounted on a rotating seat 12 driven by a rotary drive mechanism 13. The rotating seat 12 can move each rotating component 11 to the unloading device 3 to cooperate with the unloading device 3 to unload workpieces. The rotary drive mechanism 13 drives and controls the rotating seat 12 to rotate, allowing any one of the rotating components 11 to move to the unloading device 3 to cooperate with the unloading device 3 to unload workpieces. The other rotating components 11 can be used to remove the empty processing tray 100 after unloading workpieces, as well as to replenish and store processing trays 100 containing workpieces. This enables continuous and efficient replacement of processing trays 100, improving production efficiency.

[0054] In this embodiment, the rotating assembly 11 includes a mounting base 111, a turntable 112 rotatably mounted on the mounting base 111, and a rotation drive 113 connected to and driving the turntable 112 to rotate. The turntable 112 is used to support the processing disk 100. The rotation drive 113 drives the turntable 112 to rotate, thereby causing the processing disk 100 placed on the turntable 112 to rotate. This rotating assembly 11 has the advantages of simple structure, low cost, and easy control. The aforementioned rotation drive 113 uses a stepper motor, which facilitates precise control of the angular position of the rotating assembly 11.

[0055] In this embodiment, the feeding device 2 is a belt conveyor. Side baffles 22 are provided on both sides of the conveying surface of the belt conveyor to prevent the workpiece from falling off the sides of the belt conveyor during the conveying process, thus ensuring stable and reliable operation.

[0056] In this embodiment, as Figure 1 and Figure 2 As shown, the transfer device 4 is connected to an empty tray supply device 6 for supplying empty turnover trays 200 to the transfer device 4 and a palletizing device 7 for receiving and stacking turnover trays 200 filled with workpieces. This enables automatic supply of empty turnover trays 200 and automatic reception and stacking of turnover trays 200 filled with workpieces delivered by the transfer device 4, reducing manual labor intensity and improving automation and production efficiency.

[0057] Example 2 The workpiece changing system for the double-end face grinder in this embodiment is basically the same as that in Embodiment 1, with the main difference being, for example... Figure 11As shown, in this embodiment, the loading device 5 is equipped with only one loading disk drive assembly 51, which is connected to one or more sets of slots 52. The workpiece changing system for the double-end face grinder in this embodiment is equipped with only one loading disk drive assembly 51. The two operations of the slots 52 docking with the feeding device 2 to receive workpieces and the slots 52 loading workpieces into the turnover tray 200 at the transfer device 4 cannot be performed simultaneously. That is, when the slots 52 are docking with the feeding device 2 to receive workpieces, the workpiece loading into the turnover tray 200 at the transfer device 4 cannot be performed simultaneously. Similarly, when the slots 52 are loading workpieces into the turnover tray 200 at the transfer device 4, the slots 52 cannot be docking with the feeding device 2 to receive workpieces. Its efficiency is relatively low, but it can achieve the goal of arranging the workpieces output by the feeding device 2 into rows and loading them into the turnover tray 200 of the transfer device 4.

[0058] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
