Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a multi-station integrated machining fixture for hydraulic pump housing. Background Technology

[0002] As a core component of the engine cooling system, the automotive water pump functions by using a drive shaft to rotate an impeller, creating suction to draw coolant from the radiator into the engine and circulate it. This removes the heat generated during engine operation, maintaining the engine within its normal operating temperature range. The water pump housing, as a key load-bearing and flow channel structure, requires casting to form a blank, followed by grinding, cutting, and other precision machining processes to ensure dimensional accuracy and assembly compatibility. Stable fixation of the water pump housing during precision machining is a crucial prerequisite for ensuring processing quality. Most existing fixtures used in automotive water pump housing machining employ a design approach that precisely matches the external shape of the housing. While this type of fixture can achieve stable fixation in machining specific housing models, it has significant limitations: when the appearance or dimensions of the water pump housing change, the original fixture becomes unsuitable, necessitating the redesign and manufacture of a new fixture, leading to a substantial increase in production equipment costs. Even for water pump housings with similar appearances and shapes, minor dimensional differences can cause incompatibility with existing fixtures, further exacerbating the waste of fixture resources and increasing production costs, failing to meet the demand for flexible machining of multiple housing models.

[0003] To improve the adaptability of fixtures, related technical fields have made attempts to improve them. For example, Chinese utility model patent with publication number "CN220783091U" discloses a multi-station automotive water pump housing processing fixture. The fixture includes a worktable, with hydraulic adjustment rods installed on both sides of the top of the outer wall of the worktable. A clamping assembly consisting of a side connecting plate, an annular clamp, a top extension bar, a clamping component, and a connecting component is set between the two hydraulic adjustment rods. By placing the water pump housing on the top of the top extension bar, rotating the first screw and the second screw drives the first and second top balls to clamp and fix the housing at corresponding positions on the outer wall of the housing. This achieves clamping and fixing of water pump housings of various shapes within a certain size range, avoiding frequent fixture replacements due to changes in the shape and size of the housing, and playing a positive role in reducing production costs.

[0004] However, the existing patented fixture still has key functional defects in practical applications, making it difficult to meet the continuous needs of industrial production. In the actual processing flow of automotive water pump housings, the housing needs to be sequentially sent into processing equipment at different processing stations to complete multiple processes such as grinding, cutting, and drilling. This requires the fixture to have the function of station transfer and adjustment of the water pump housing after clamping and positioning. However, the aforementioned patented fixture can only clamp and fix the housing at each station, lacking the ability to transfer and adjust in a reciprocating cycle. It cannot accurately send the clamped water pump housing into the processing equipment at different processing stations, resulting in the entire processing process relying on manual or additional equipment for housing transfer. This makes it impossible to achieve high-intensity, continuous, and uninterrupted production processing, which not only reduces the overall production efficiency but also increases the error risk caused by manual intervention. The overall production process has obvious defects and urgently needs to be improved to overcome the bottleneck of continuous production. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a multi-station integrated machining fixture for hydraulic pump housings, which can more accurately solve the problems described above.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a multi-station integrated machining fixture for hydraulic pump housing, including a worktable, a rotating module fixedly installed in the middle of the worktable, a moving module fixedly installed in a ring at equal intervals on the outer side of the rotating module, a clamping module fixedly installed at the outer end of the moving module, and machining stations fixedly installed in a ring at equal intervals on the outer side of the worktable.

[0008] The rotating module includes a base, which is fixedly installed in the middle of the bottom of the workbench. A first motor is fixedly installed at the bottom of the base. A turntable is fixedly installed through the output end of the first motor through the base. A fixing block is fixedly installed on the top of the turntable. The moving modules are arranged in a ring at equal intervals and fixedly installed on the outside of the fixing block.

[0009] Furthermore, a mounting arm is fixedly installed on the bottom outer side of the processing station, and a processing equipment mounting plate is fixedly installed on the outer end of the mounting arm.

[0010] Furthermore, mounting holes are provided at all four corners of the mounting plate of the processing equipment. The mounting holes are countersunk holes, and the outer edges of the mounting plate are all rounded.

[0011] Furthermore, the mobile module includes a fixed frame, which is fixedly installed on the outside of the fixed block in a ring with equal spacing. An electric push rod is fixedly installed on the outside of the fixed frame, and a connecting rod is fixedly installed on the outer end of the electric push rod. The outer end of the connecting rod clamps and is fixedly connected to the inner side of the module.

[0012] Furthermore, the clamping module includes a receiving plate, which is fixedly installed on the outer end of the connecting rod. A sliding groove is provided in the middle of the receiving plate. A second motor is fixedly installed on one side of the receiving plate. The output end of the second motor is fixedly connected to one end of the lead screw. The two ends of the lead screw have opposite thread directions. A slider is threadedly connected to the outer end of the lead screw. A fine-tuning clamp is fixedly installed on the top of the slider.

[0013] Furthermore, a support rail is fixedly installed at the bottom of the electric push rod, a support frame is slidably connected inside the support rail, a support plate is fixedly installed at the outer end of the support frame, the top of the support plate and the bottom of the receiving plate are fixedly connected, and ball bearings are rotatably connected at equal intervals at the bottom of the support plate.

[0014] Furthermore, the fine-tuning clamp assembly includes a base plate, which is fixedly installed on the top of the slider. A vertical adjustment rail is fixedly installed on the top of the base plate. A vertical adjustment plate is slidably connected inside the vertical adjustment rail. A V-shaped clamping plate is fixedly installed on the inner side of the vertical adjustment plate. A limit screw is threadedly connected to one side of the upper end of the vertical adjustment rail. The end of the limit screw passes through the vertical adjustment rail. Limit holes are evenly spaced on the side of the vertical adjustment plate near the limit screw. The end of the limit screw is inserted into the limit hole.

[0015] The beneficial effects of this utility model are:

[0016] 1. During the application of this technical solution, by setting up replaceable vertical adjustment plates and clamping plates for the fine-tuning clamping group, and in conjunction with the base plate, vertical adjustment rail, and the fixing structure of limit screws and limit holes, the vertical adjustment plate can be quickly pulled out and the appropriate clamping plate replaced according to the shape and specifications of the hydraulic pump housing to be processed, without replacing the entire fixture. At the same time, with the cooperation of the second motor, lead screw, slider and slide groove, the lateral distance between the two sets of fine-tuning clamping groups can be adjusted to further adapt to housings of different widths, thereby achieving the effect of a single fixture adapting to housings of multiple shapes and specifications. This solves the problems of poor fixture adaptability, frequent fixture replacement due to changes in housing shape and size in the prior art, and increased production costs, and greatly improves the versatility and flexible processing capability of the fixture.

[0017] 2. During the application of this technical solution, by setting up a base for the rotating module, a first motor, a turntable, and a fixed block, and cooperating with the processing stations arranged in a ring on the outer side of the worktable, the first motor can drive the turntable to rotate, accurately transferring the clamped and fixed housing to each processing station during use. At the same time, the electric push rod, support rail, and support frame of the moving module can adjust the lateral position of the housing, ensuring smooth processing and transfer. Multiple sets of moving modules can also realize alternating operations of loading, processing, and unloading, thereby achieving the effect of automatic transfer and continuous production of housing at multiple stations. This solves the problems of existing technologies, such as the lack of transfer function of the fixture, the need for manual or additional equipment to assist in transfer, the inability to achieve high-intensity continuous production, and the resulting low production efficiency, reducing manual intervention and reducing processing errors.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A multi-station integrated machining fixture for hydraulic pump housing includes a worktable 1, a rotating module 2 fixedly installed in the middle of the worktable 1, a moving module 3 fixedly installed in a ring at equal intervals on the outer side of the rotating module 2, a clamping module 4 fixedly installed at the outer end of the moving module 3, and machining stations 5 fixedly installed in a ring at equal intervals on the outer side of the worktable 1.

[0027] The rotating module 2 includes a base 21, which is fixedly installed at the bottom center of the workbench 1. A first motor 22 is fixedly installed at the bottom of the base 21. A turntable 23 is fixedly installed through the output end of the first motor 22 through the base 21. A fixing block 24 is fixedly installed on the top of the turntable 23. The moving modules 3 are arranged in a ring at equal intervals and fixedly installed on the outside of the fixing block 24. During the application of this device, it first provides a basic support platform for the entire fixture through the workbench 1, ensuring the rotation module 2, the moving module 3, and the fixture are supported. Both the holding module 4 and the processing station 5 can operate stably. When multi-station processing of the hydraulic pump housing is required, the housing to be processed is first placed on the holding module 4, and the housing is clamped and fixed by the holding module 4. Then, the rotating module 2 is started. The base 21 of the rotating module 2 provides stable support for the first motor 22 and the turntable 23. After the first motor 22 is started, the output end drives the turntable 23 to rotate. The fixed block 24 on the top of the turntable 23 rotates synchronously with the turntable 23. The moving module 3 and the outer end of the fixed block 24 rotate synchronously. The clamping module 4 also rotates, which in turn drives the fixed housing to rotate synchronously. By controlling the rotation angle of the first motor 22, the housing can be accurately transferred to one of the processing stations 5 arranged in a ring outside the worktable 1. At this time, the processing station 5 can perform the corresponding process on the housing. After the processing is completed, the first motor 22 is started again, driving the turntable 23 to continue rotating and transferring the housing to the next processing station 5. All processing processes are completed in sequence. During this process, the rotating module 2 realizes the automatic transfer of the housing between multiple processing stations 5 through the cooperation of the first motor 22 and the turntable 23. No manual or additional equipment assistance is required, which solves the problem of lack of transfer function and low production efficiency of the existing fixtures. The moving module 3 rotates synchronously with the fixed block 24, which can help maintain the stability of the clamping module 4 and the housing during the transfer process, ensuring that the housing is accurately positioned when transferred to the processing station 5, avoiding the impact of transfer deviation on the processing quality, thereby improving the continuity and stability of multi-station processing and meeting the needs of high-intensity production.

[0028] Combination Figures 1-4 As shown, a mounting arm 6 is fixedly installed on the bottom outer side of the processing station 5. A processing equipment mounting plate 7 is fixedly installed on the outer end of the mounting arm 6. Mounting holes 8 are provided at the four corners of the processing equipment mounting plate 7. The mounting holes 8 are countersunk holes. The outer edges of the mounting plate are all rounded. The moving module 3 includes a fixing frame 31. The fixing frames 31 are arranged in a ring at equal intervals and fixedly installed on the outer side of the fixing block 24. An electric push rod 32 is fixedly installed on the outer side of the fixing frame 31. A connecting rod 33 is fixedly installed on the outer end of the electric push rod 32. The outer end of the connecting rod 33 clamps and is fixedly connected to the inner side of the module 4.

[0029] In the above-described embodiments of this application, during the application of this device, it first fixes the processing equipment mounting plate 7 in a designated position according to the processing requirements using the mounting arm 6 on the outer side of the bottom of the processing station 5. The mounting arm 6 provides stable support for the processing equipment mounting plate 7, ensuring that the subsequent processing equipment will not shift after installation. Then, using the mounting holes 8 at the four corners of the processing equipment mounting plate 7, the grinding, cutting, and other processing equipment are fixed to the mounting plate with bolts. The mounting holes 8 are countersunk holes, which allow the bolt heads to be fully embedded in the holes, preventing the bolt heads from protruding and interfering with the operation of the processing equipment. At the same time, the outer edges of the mounting plate are rounded, which can prevent damage to the operator due to bumps during operation and improve operational safety. Before clamping the hydraulic pump housing, the electric push rod 32 of the moving module 3 is activated. The fixing frame 31 provides a stable mounting base for the electric push rod 32, ensuring that the electric push rod 32 will not shake during operation. The output end of the electric push rod 32 extends or retracts, driving the connecting rod 33 to move in the horizontal direction, thereby driving the connecting rod 32 to move in the horizontal direction. The clamping module 4 connected to module 3 is adjusted until it moves to a preset position that is convenient for receiving the housing to be processed. After the housing is placed in the clamping module 4 and fixed, the electric push rod 32 is activated again. By controlling its extension and retraction, the clamping module 4 and the housing are precisely moved to the effective processing range of the processing equipment, ensuring that the processing equipment can accurately process the housing. During this process, the countersunk hole design of the processing equipment mounting plate 7 avoids the interference of bolts on the processing, and the rounded corners improve the safety of operation, solving the problems of easy installation of equipment affected by bolts and safety hazards in operation in the prior art. The electric push rod 32 of the moving module 3 drives the clamping module 4 to flexibly adjust its position through the connecting rod 33. There is no need to manually move the housing or adjust the entire fixture. This not only saves manpower, but also ensures the accuracy of the housing position adjustment, avoiding the decline in processing quality due to manual adjustment deviation. This improves the efficiency of pre-processing preparation and the stability of subsequent processing, meeting the position adaptation requirements when processing multiple specifications of housing.

[0030] Example 2

[0031] Combination Figures 1-5As shown, the clamping module 4 includes a receiving plate 41, which is fixedly installed on the outer end of the connecting rod 33. A groove 42 is provided in the middle of the receiving plate 41. A second motor 43 is fixedly installed on one side of the receiving plate 41. The output end of the second motor 43 is fixedly connected to one end of a lead screw 46. The two ends of the lead screw 46 have opposite thread directions. A slider 44 is threadedly connected to the outer end of the lead screw 46. A fine-tuning clamp 45 is fixedly installed on the top of the slider 44. A support rail 34 is fixedly installed at the bottom of the electric push rod 32. A support frame 35 is slidably connected inside the support rail 34. A support plate 36 is fixedly installed on the outer end of the support frame 35. The top of the support plate 36 is fixedly connected to the bottom of the receiving plate 41. The bottom of the 6 is rotatably connected with ball bearings 37 at equal intervals. The fine-tuning clamp assembly 45 includes a base plate 451, which is fixedly installed on the top of the slider 44. A vertical adjustment rail 452 is fixedly installed on the top of the base plate 451. A vertical adjustment plate 453 is slidably connected inside the vertical adjustment rail 452. A V-shaped clamping plate 454 is fixedly installed on the inner side of the vertical adjustment plate 453. A limit screw 456 is threadedly connected to one side of the upper end of the vertical adjustment rail 452. The end of the limit screw 456 passes through the vertical adjustment rail 452. Limit holes 455 are evenly arranged on the side of the vertical adjustment plate 453 near the limit screw 456. The end of the limit screw 456 is inserted into the limit hole 455.

[0032] In the above-described embodiments of the present application, during the application of this device, when clamping the hydraulic pump housing, the housing is first placed on the receiving plate 41, which provides a bearing base for the housing. The second motor 43 on one side of the receiving plate 41 is started, and the output end of the second motor 43 drives the lead screw 46 to rotate. Because the threads at both ends of the lead screw 46 turn in opposite directions, and the lead screw 46 is threadedly connected to the slider 44, and the slide groove 42 in the middle of the receiving plate 41 restricts the slider 44 to slide only along the slide groove 42, when the lead screw 46 rotates, it drives the sliders 44 at both ends to slide along the slide groove 42. As the slides 42 move towards each other, the fine-tuning clamp 45 on top of the slider 44 moves synchronously towards the housing. The base plate 451 of the fine-tuning clamp 45 provides mounting support for the vertical adjustment rail 452, pushing the vertical adjustment plate 453 inside the vertical adjustment rail 452 so that the V-shaped clamping plate 454 on the inner side of the vertical adjustment plate 453 fits against the outer wall of the housing. Then, the limiting screw 456 at the upper end of the vertical adjustment rail 452 is rotated so that the end of the limiting screw 456 passes through the vertical adjustment rail 452 and is inserted into the limiting hole 455 of the vertical adjustment plate 453, thus fixing the vertical adjustment rail 452. The position of the adjusting plate 453 is used to clamp the housing. During the adjustment of the position by the moving module 3 driving the clamping module 4, the support rail 34 at the bottom of the electric push rod 32 cooperates with the internally slidingly connected support frame 35 to provide lateral guidance for the support plate 36. The top of the support plate 36 is fixedly connected to the bottom of the receiving plate 41, which helps the receiving plate 41 maintain stable movement. The equally spaced rotating ball bearings 37 at the bottom of the support plate 36 reduce friction between the support plate 36 and the surface of the worktable 1, preventing jamming during the movement of the receiving plate 41. The V-shaped clamping plate 454 can adapt to shells of different shapes. With the fixing of the limiting screw 456 and the limiting hole 455, it ensures stable clamping of the shell and solves the problem of poor adaptability of the clamping structure in the prior art. The cooperation of the support rail 34, the support frame 35 and the ball bearing 37 ensures smooth and accurate movement of the receiving plate 41, avoids shell position deviation due to movement deviation, and thus improves processing accuracy. At the same time, the mechanized clamping adjustment does not require manual fixing, saving manpower and reducing operation error, and meeting the stable clamping requirements of shells of various specifications.

[0033] The working principle and advantages of this utility model are as follows: During the application of this device, firstly, preliminary preparation work is carried out. The first step is to fix the processing equipment. The processing equipment mounting plate 7 is connected to the mounting arm 6 on the outer side of the bottom of the processing station 5. The mounting arm 6 provides stable support for the mounting plate during use through its own support structure, preventing the mounting plate from tilting due to the weight of the equipment. Countersunk mounting holes 8 are opened at the four corners of the processing equipment mounting plate 7. By setting the countersunk structure, the head of the bolt can be completely embedded in the hole after it is inserted during use, preventing the bolt head from protruding and obstructing the operation of the processing equipment. At the same time, the outer edges of the mounting plate are rounded. This design prevents the operator from bumping into the edges during use, improving operational safety. Then, according to the shape and specifications of the hydraulic pump housing to be processed, the fine-tuning clamping group 45 of the clamping module 4 is adjusted in advance. The base plate 451 of the fine-tuning clamping group 45 is fixed on the top of the slider 44. Through the fixing effect of the base plate 451, a stable mounting base is provided for the vertical adjustment rail 452 during use. First, rotate the limiting screw 456 at the upper end of the vertical adjusting rail 452. The limiting screw 456 moves laterally along the vertical adjusting rail 452 through threaded engagement, causing its end to disengage from the limiting hole 455 of the vertical adjusting plate 453, thus releasing the fixation of the vertical adjusting plate 453. Then, pull out the vertical adjusting plate 453 inside the vertical adjusting rail 452 and replace it with another clamping plate that is suitable for the current housing shape and specifications. After the replacement is completed, insert the new vertical adjusting plate 453 into the vertical adjusting rail 452 and push the adjusting plate to make the clamping plate and the housing... The body is pre-fitted with the clamping surface, and finally the limiting screw 456 is screwed in and inserted into the corresponding limiting hole 455. The position of the vertical adjustment plate 453 is fixed by the cooperation of the limiting screw 456 and the limiting hole 455, thus completing the initial adaptation and adjustment of the fine-tuning clamping assembly 45. This design, by setting a replaceable vertical adjustment plate 453 and clamping plate, eliminates the need to replace the entire clamp during use. Only the clamping plate needs to be replaced to adapt to shells of different shapes and specifications, thereby solving the problem of poor clamp adaptability and frequent replacement required in the prior art.

[0034] Next, the housing is loaded and clamped. The first motor 22 at the bottom of the base 21 of the rotating module 2 is started. The base 21 is fixed in the middle of the bottom of the workbench 1. The base 21 provides stable support for the first motor 22 and the turntable 23 during use. The output end of the first motor 22 drives the turntable 23 to rotate. The fixed block 24 on the top of the turntable 23 rotates synchronously with the turntable 23. The moving module 3 outside the fixed block 24 rotates with the fixed block 24 until one set of moving modules 3 is aligned with the loading position. Then the motor is turned off and the electric push rod 32 on the outside of the fixing frame 31 of the moving module 3 is started. The fixing frame 31 is fixed to the outside of the fixing block 24. The fixing frame 31 provides stable support for the electric push rod 32 during use. The output end of the electric push rod 32 extends, driving the connecting rod 33 to move horizontally. The outer end of the connecting rod 33 is fixedly connected to the receiving plate 41, thereby driving the receiving plate 41 to move closer to the loading position. At the same time, the electric push rod... The support rail 34 at the bottom of the 32 is internally connected to the support frame 35, and the support plate 36 at the outer end of the support frame 35 is fixedly connected to the bottom of the receiving plate 41. Through the cooperation of the support rail 34 and the support frame 35, the receiving plate 41 can be provided with lateral support during use, preventing the receiving plate 41 from tilting due to cantilever force. The ball bearing 37 rotatably connected to the bottom of the support plate 36 reduces the friction between the support plate 36 and the surface of the worktable 1 during use through the rolling characteristics of the ball bearing 37, assisting the receiving plate 41 to move smoothly. After the shell to be processed is placed on the receiving plate 41, the second motor 43 on one side of the receiving plate 41 is started. The output end of the second motor 43 drives the lead screw 46 to rotate. The threads at both ends of the lead screw 46 turn in opposite directions, and the outer end of the lead screw 46 is threadedly connected to the slider 44. The groove 42 opened in the middle of the receiving plate 41 restricts the slider 44 to slide only along the length direction of the groove 42, so that when the lead screw 46 rotates during use, it can drive the sliders 44 at both ends to move towards each other along the groove 42.The fine-tuning clamps 45 on top of the slider 44 move synchronously with the slider 44 until the clamping plates of the two fine-tuning clamps 45 are in contact with the outer wall of the housing, completing the clamping and fixing of the housing. The entire clamping process is mechanically adjusted, enabling precise positioning during use and avoiding errors from manual fixing, thereby improving clamping stability. Then, the housing is transferred and processed at the work station. The electric push rod 32 of the moving module 3 is activated, controlling the electric push rod 32 to retract, driving the receiving plate 41 and the fixed housing to reset horizontally until the housing is within the preset processing range of the turntable 23. The electric push rod 32 is then turned off, and the first motor 22 is restarted. The rotating turntable 23 continues to rotate, and the moving module 3, clamping module 4, and housing on the outside of the fixed block 24 rotate synchronously with the turntable 23. By controlling the rotation angle of the first motor 22, the housing can be accurately aligned with the first processing station 5 on the outside of the worktable 1 during use. The motor is turned off, and the equipment at the processing station 5 is started to process the housing. During processing, the limiting screw 456 of the fine-tuning clamping group 45 and the limiting hole 455 are engaged, so that the clamping plate continuously applies clamping force to the housing to prevent the housing from loosening. The support rail 34 and the support frame 35 continuously provide support for the receiving plate 41, so that the housing can be prevented from shifting due to processing force during use.

[0035] After the first workstation is completed, the first motor 22 is restarted, driving the turntable 23 to transfer the housing to the next processing workstation 5. The above processing steps are repeated until all workstation processes are completed. This technical solution, by setting up the rotating module 2, enables automatic transfer of the housing between multiple workstations during use, without the need for manual labor or additional equipment assistance. This solves the problem of existing patented fixtures lacking transfer functions and being unable to achieve continuous production, greatly improving production efficiency. Finally, the cycle operation and unloading are performed. After the housing completes all processing steps, the turntable 23 transfers it to the unloading position. First, the limiting screw 456 of the fine-tuning clamping group 45 is rotated so that the end of the limiting screw 456 disengages from the limiting hole 455, and the vertical adjustment plate 453 is pulled out. If the same specification housing is processed subsequently, there is no need to replace the clamping plate. The current vertical adjustment plate 453 is retained, the housing is released from fixation, and the processed housing is removed. At the same time, the fine-tuning clamping group 45 of another set of moving modules 3 can be pre-adjusted at the loading position. If the clamping plate needs to be replaced, it should be replaced in advance, and a new shell to be processed should be placed. After the previous set of shells has finished unloading, the first motor 22 is started to drive the turntable 23 to rotate, and the newly loaded shell is transferred to the processing station 5. Through the alternating operation of multiple sets of moving modules 3, continuous cyclic operation can be achieved during use. In the whole process, the various structures work together: the cooperation between the mounting plate and the mounting arm 6 allows it to adapt to different types of processing equipment during use; the electric push rod 32, the support rail 34 and the support frame 35 of the moving module 3 ensure the accurate position of the shell during use; the replaceable clamping plate and the limiting structure of the fine-tuning clamping group 45 allow it to adapt to multiple specifications of shells during use; the first motor 22 and the turntable 23 of the rotating module 2 ensure smooth transfer at the station during use. Through the cooperation of all the structures, the high-intensity continuous production needs can be fully met during use, while reducing manual intervention, thereby reducing processing errors and production costs.
