Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a turntable module and a micro-product continuous automatic processing equipment having the turntable module. Background Technology

[0002] The challenge in automated machining of miniature products lies in the precise positioning of the product, such as a titanium alloy mobile phone nut with an outer diameter of only 2.15mm, as shown in the instruction manual. Figure 14 As shown, due to its advantages such as corrosion resistance, non-magnetic properties, and high strength, it has been applied in fields such as smartphones and watches. However, due to its small size, it is difficult to fix in place during automated processing, resulting in problems such as low production yield and processing difficulties. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a continuous automatic processing equipment for micro products, which adopts processes such as automatic feeding, staggered feeding, turntable conveying, limiting, processing positioning, and unloading to realize fully automatic continuous processing of micro products, with stable production process and high efficiency.

[0004] One technical solution adopted by the present invention to solve its technical problem is: to provide a turntable module, which is set on a worktable. The turntable module includes a divider, a first drive mechanism and a turntable. The divider and the first drive mechanism are located at the lower part of the worktable, and the turntable is rotatably located at the upper part of the worktable.

[0005] The divider has an input shaft and an output shaft that is driven to the input shaft via a cam roller assembly; the output shaft of the divider passes vertically through the worktable and extends to the upper part of the worktable; the turntable is connected to the end of the output shaft of the divider; the first drive mechanism is driven to the input shaft of the divider and is used to drive the input shaft to rotate the output shaft, thereby causing the turntable to rotate around its axis.

[0006] The upper part of the worktable is provided with a bearing, which is located between the turntable and the worktable, and the inner ring of the bearing is fitted onto the output shaft of the divider.

[0007] As a further improvement of the present invention, the outer ring of the bearing is fixedly connected to the worktable, a synchronous pulley A is connected to the output shaft of the first drive mechanism, a synchronous pulley B is provided on the input shaft of the divider, and the synchronous pulley A and the synchronous pulley B are connected by a synchronous belt drive.

[0008] Another technical solution provided by the present invention is to provide a continuous automatic processing equipment for micro products, the processing equipment comprising:

[0009] The workbench is provided with at least a loading station and a processing station.

[0010] A feeding module is located on one side of the loading station and is used to transport the micro-products to be processed with a specified orientation to the loading station one by one.

[0011] The turntable module has a loading station and a processing station arranged circumferentially around the turntable of the turntable module. The turntable has multiple product positioning molds near its edge. When the turntable rotates, it drives the product positioning molds to the loading station and the processing station in sequence. When one product positioning mold is located at the loading station, another product positioning mold is located at the processing station.

[0012] A limiting module includes a limiting flow channel surrounding the turntable and disposed between the loading station and the processing station, the limiting flow channel being used to limit the micro product to be processed, which is placed on the product positioning mold, to be positioned on the product positioning mold.

[0013] A processing positioning module is disposed on the processing station and is used to fix the micro product to be processed after it arrives at and stops at the processing station. The processing positioning module includes a first positioning mechanism for elastically pressing the upper surface of the micro product, and a processing mechanism for processing the holes of the micro product. The processing mechanism includes a processing tool and a processing drive unit for driving the processing tool to lift and rotate.

[0014] As a further improvement of the present invention, the feeding module includes a vibratory feeder, a conveying channel disposed at the outlet end of the vibratory feeder, and a staggered feeding mechanism disposed at the outlet end of the conveying channel.

[0015] The staggered feeding mechanism includes a material distribution unit arranged perpendicular to the conveying direction of the conveying channel, and a material pushing unit arranged perpendicular to the conveying direction of the material distribution unit and located next to the feeding station.

[0016] In this process, the micro-products to be processed in the vibratory feeder are arranged sequentially in the conveying channel with a specified orientation under the action of vibration. At the same time, the turntable rotates, causing one of the product positioning molds on it to move to the loading station. A micro-product located at the outlet end of the conveying channel is transferred to the front side of the pushing unit through the material distribution unit. Then, the pushing unit pushes the micro-product onto the product positioning mold that has arrived at the loading station.

[0017] As a further improvement of the present invention, the staggered feeding mechanism further includes a staggered feeding unit, which includes a material distribution channel and a material pushing channel that are perpendicular to and connected to each other. The material distribution channel is connected to the conveying channel and is arranged perpendicular to the conveying channel, and the material pushing channel is arranged parallel to the conveying channel.

[0018] The material distribution unit includes a material distribution rod slidably connected to the material distribution channel and a material distribution cylinder pulverizedly connected to the material distribution rod. The material distribution rod is provided with a material distribution groove that connects to the conveying channel and the pushing channel. The material distribution cylinder is located on one side of the conveying channel and is used to drive the material distribution rod to move the material distribution groove back and forth between the two connection points of the conveying channel and the pushing channel.

[0019] The pushing unit includes a pushing rod slidably connected to the pushing channel and a pushing cylinder pulverizedly connected to the pushing rod. The pushing cylinder is located on the other side of the conveying channel and is used to drive the pushing rod to push the miniature product placed in the material distribution groove onto the product positioning mold that has arrived at the loading station.

[0020] As a further improvement of the present invention, the first positioning mechanism is supported on the upper part of the turntable by a connecting frame, including a positioning block perpendicular to the turntable, a lifting cylinder disposed on the side of the positioning block facing the center of the turntable, and a movable block movably disposed on the other side of the positioning block and drivenly connected to the lifting cylinder. A return spring is provided between the upper end of the movable block and the positioning block, and a pressing block is provided at the lower end of the movable block for pressing the outer edge of the upper surface of the micro product to be processed.

[0021] As a further improvement of the present invention, the processing positioning module further includes a second positioning mechanism disposed on the processing station of the worktable. The second positioning mechanism is disposed on the outside of the limiting module. The limiting module further includes a guide groove disposed radially along the turntable and communicating with the limiting flow channel.

[0022] The second positioning mechanism includes a positioning pin slidably connected to the guide groove and a positioning cylinder pulsatingly connected to the positioning pin. The positioning cylinder is used to drive the positioning pin to reciprocate within the guide groove, so that the end of the positioning pin is inserted into the product positioning mold to fix the circumference of the micro product to be processed, or to drive the end of the positioning pin away from the micro product after the micro product has been processed.

[0023] As a further improvement of the present invention, the workbench is also provided with a feeding module, the feeding module including a guide groove arranged around the turntable and a feeding mechanism arranged on the other side of the turntable opposite to the feeding module;

[0024] The unloading mechanism includes an unloading push rod that is vertically arranged on the turntable, and a lifting cylinder for driving the unloading push rod to move up and down. The lifting cylinder is used to drive the unloading push rod to push the miniature product that has been processed on the product positioning mold directly below the unloading push rod into the guide groove.

[0025] One end of the guide trough is connected to the limiting flow channel of the limiting module, and the other end passes directly below the unloading mechanism and extends to the outside of the worktable.

[0026] As a further improvement of the present invention, the workbench is provided with a first platform and a second platform on both sides, and the first platform is higher than the second platform. The workbench is inclined downward from one side of the first platform and extends to one side of the second platform.

[0027] The vibratory feeder is supported above the first platform by a bracket, so that the conveying channel slopes downward from the outlet end of the vibratory feeder and is parallel to the worktable;

[0028] The second platform is equipped with a receiving bin that connects to the guide trough.

[0029] As a further improvement of the present invention, the worktable is provided with a cleaning module on the other side of the turntable opposite to the processing positioning module, and the cleaning module has a cleaning component for cleaning the upper surface of the turntable passing below the cleaning module.

[0030] The beneficial effects of this invention are:

[0031] 1. The feeding module, limiting module, processing positioning module, unloading module and cleaning module set around the turntable module realize the fully automated processing of micro products. The overall structure of the equipment is compact and the processing efficiency is high.

[0032] 2. By installing bearings on the divider of the turntable module, the accuracy of the turntable is ensured and the service life of the divider is improved;

[0033] 3. By setting up a staggered feeding mechanism, the operation of the turntable and the feeding mechanism is ensured to be coordinated, while preventing the material from being crowded and stuck during the feeding process, thus ensuring the stability of the feeding process;

[0034] 4. Through the coordinated action of the product positioning module, the first positioning mechanism, the second positioning mechanism, and the limiting module, the material is limited and fixed in the circumferential direction and on the upper and lower end faces, thereby ensuring that the material will not shake or rotate during processing and ensuring processing quality.

[0051] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] See Figures 1 to 13 The micro-product continuous automatic processing equipment provided by the present invention includes a worktable 1, a turntable module 2, a feeding module 3, a limiting module 4, a processing positioning module 5, a unloading module 6, a cleaning module 7, and a control module 8. The control module 8 uses an existing PLC or Siemens control system to control the coordinated actions between the above modules, so that the above modules cooperate to realize the automatic feeding, positioning processing, and automatic unloading of micro-products for continuous and uninterrupted automatic processing.

[0053] Among them, the turntable module 2 has a turntable 23 that rotates relative to the worktable 1. The feeding module 3, the limiting module 4, the processing positioning module 5, the unloading module 6 and the cleaning module 7 are centrally symmetrically distributed around the rotation axis of the turntable 23. This layout is based on the transfer method of the turntable 23, which shortens the transfer time of micro products between modules, improves processing efficiency, and makes the equipment structure compact in space.

[0054] See Figure 14This invention provides a structural embodiment of a miniature product 100, namely a conventional titanium alloy mobile phone nut. The miniature product 100 has an overall "I" shape with a through hole in its center. The processing equipment embodiment provided by this invention can be used to chamfer the end face of the through hole or to perform thread processing inside the hole. The miniature product 100 has an upper part 101, a lower part 102, and a connecting part 103 connecting the upper part 101 and the lower part 102. Of course, providing this structure for the miniature product facilitates subsequent description. The processing equipment of this invention is also applicable to commonly used "T"-shaped miniature products; it is easy to understand that different product positioning molds and processing tools can be used to replace the existing ones for different structures of miniature products.

[0055] See Figure 1 The workbench 1 of the present invention is inclined, with a first platform 11 and a second platform 12 arranged horizontally on both sides, and the first platform 11 is higher than the second platform 12. The workbench 1 is inclined downward from one side of the first platform 11 and extends to one side of the second platform 12; that is, the high end of the workbench 1 is higher than the first platform 11. The inclined arrangement of the workbench 1 facilitates the sliding of the micro products in the conveying channel 32 of the feeding module 3 to the distributing trough 3311 of the distributing unit 33 by gravity.

[0056] See Figures 1 to 5 The feeding module 3 provided by the present invention is located on one side of the loading station and is used to transport the micro products to be processed with a specified orientation (i.e., the lower part 102 of the micro product is facing down) one by one to the product positioning module 231 that has arrived at the loading station.

[0057] Example 1: A vibratory feeder 31 is used for feeding materials, and a conveying channel 32 is provided at the outlet end of the vibratory feeder 31.

[0058] The vibratory feeder 31 is supported above the first platform 11 by a bracket 36, so that the conveying channel 32 slopes downward from the outlet end of the vibratory feeder 31 and is parallel to the workbench 1. The structure of the conveying channel 32 is adapted to the shape of the micro products, so that the micro products are stacked in rows in the conveying channel 32. At the same time, a linear vibrator 37 is set below the conveying channel 32 to provide power for the movement of the micro products in the conveying channel 32. Sensors 321 are set at both the inlet and outlet ends of the conveying channel 32 to monitor the loading and unloading of the vibratory feeder 31 in real time. The outlet end of the conveying channel 32 is directly connected to the product positioning mold 231 on the turntable 23 to realize the automatic feeding of micro products.

[0059] Example 2: The difference from Example 1 is that a staggered feeding mechanism is set at the outlet end of the conveying channel 32. The staggered feeding mechanism is connected to the product positioning mold 231 on the turntable 23. This method can ensure that the micro products are transferred one by one and there will be no jamming during the feeding process of the conveying channel 32, ensuring the smoothness of the feeding process and preventing the micro products from crowding in front of the product positioning mold 231.

[0060] Specifically, the staggered feeding mechanism includes a material distribution unit 33 arranged in the conveying direction of the vertical conveying channel 32, a material pushing unit 34 arranged in the conveying direction of the vertical material distribution unit 33 and located next to the feeding station, and a staggered feeding unit 35.

[0061] The staggered feeding unit 35 includes a material distribution channel 351 and a pushing channel 352 that are perpendicular to and connected to each other. The material distribution channel 351 is connected to and perpendicular to the conveying channel 32, while the pushing channel 352 is parallel to the conveying channel 32. The material distribution unit 33 includes a material distribution rod 331 that is slidably connected to the material distribution channel 351, and a material distribution cylinder 332 that is pultrusively connected to the material distribution rod 331. The material distribution rod 331 is provided with a material distribution groove 3311 that connects to the conveying channel 32 and the pushing channel 352. The material distribution cylinder 331... 2 is located on one side of the conveying channel 32 and is used to drive the material distribution rod 331 to move the material distribution groove 3311 back and forth between the two docking points of the conveying channel 32 and the pushing channel 352; the pushing unit 34 includes a pushing rod 341 slidably connected to the pushing channel 352 and a pushing cylinder 342 pulverizedly connected to the pushing rod 341. The pushing cylinder 342 is located on the other side of the conveying channel 32 and is used to drive the pushing rod 341 to push the miniature product placed in the material distribution groove 3311 to the product positioning mold 231 that has reached the loading station.

[0062] The material distribution channel 351 and the material pushing channel 352 are arranged in a cross shape. This provides guiding support for the material distribution rod 331 and the material pushing rod 341, and also prevents motion interference between them. In this design, the micro-products are transferred between the conveying channel 32 and the product positioning mold 231 in a "Z" shaped path. In addition, since the material distribution rod 331 is equipped with a material distribution slot 3311 that allows only a single micro-product to enter, when the material distribution slot 3311 of the material distribution rod 331 receives a micro-product at the outlet end of the conveying channel 32, it immediately moves towards the side of the material pushing rod 341. During the movement, the side of the material distribution rod 331 blocks the outlet of the conveying channel 32, thereby ensuring that the material distribution rod 331 transfers only one micro-product per reciprocation, ensuring that the micro-products are conveyed one by one while preventing congestion of micro-products at the loading station.

[0063] See Figures 6 to 7The turntable module 2 provided by the present invention includes a divider 21 and a first drive mechanism 22 disposed at the lower part of the worktable 1, and a turntable 23 rotatably disposed at the upper part of the worktable 1.

[0064] The divider 21 is a cam divider, which has an input shaft that is driven by the first drive mechanism 22 and an output shaft that is driven by the cam rolling resistance. The output shaft of the divider 21 vertically passes through the worktable 1 and extends to the upper part of the worktable 1. The end of the output shaft is connected to the turntable 23. The output shaft of the first drive mechanism 22 is connected to a synchronous pulley A221. The input shaft of the divider 21 is provided with a synchronous pulley B211. The synchronous pulley A221 and the synchronous pulley B211 are driven by a synchronous belt 25, thereby driving the input shaft of the divider 21 to drive the output shaft to rotate, and thus causing the turntable 23 to rotate around its axis. The angle of each rotation of the turntable 23 is achieved by the structural design of the cam rolling resistance of the cam divider and the output turret. The cam divider is existing technology and will not be described in detail in this invention.

[0065] In addition, since the processing station is located on one side of the turntable 23, when the micro product is processed at the processing station, a downward force will be generated at the edge of the turntable 23, which will generate an eccentric force on the output shaft of the divider 21. Long-term use will reduce the accuracy of the divider and shorten its service life.

[0066] Therefore, the present invention provides a bearing 24 on the upper part of the worktable 1. The inner ring of the bearing 24 is sleeved on the output shaft and located between the turntable 23 and the worktable 1. The outer ring diameter of the bearing 24 is slightly smaller than the diameter of the turntable 23, so that the force of the micro product during processing will be applied to the bearing, while the divider 21 only provides the rotational dividing accuracy of the turntable 23. This improves the service life of the divider while ensuring the dividing accuracy, and also reduces the operating cost of the divider to a certain extent.

[0067] In addition, multiple positioning slots are provided on the turntable 23, which are centrally symmetrically distributed around the rotation axis of the turntable 23. Each positioning slot is detachably connected to a product positioning mold 231. The product positioning mold 231 has a positioning hole portion adapted to the shape of the miniature product on the side away from the center of the turntable 23. The detachable connection between the product positioning mold 231 and the turntable 23 allows for the selection of product positioning molds with different positioning hole portions according to different structures of miniature products, improving the versatility of processing. Furthermore, the positioning slots on the turntable are configured such that each time the turntable rotates, a product positioning mold 231 is respectively located at the loading station, processing station, and unloading station.

[0068] See Figure 5A limiting module 4 is set near the rotation path of the turntable and between the loading station and the processing station. The limiting channel 41 of the limiting module 4 has a horizontal plane parallel to the worktable 1 and a limiting surface surrounding the outer circumference of the turntable. The inlet end of the limiting channel 41 is connected to the outlet end of the push channel 352; the outlet end of the limiting channel 41 is connected to the guide groove 61. Thus, when the product positioning mold 231 receives the miniature product from the outlet end of the push channel 352, during the process of the turntable 23 rotating from the loading station to the processing station, the lower part of the miniature product is supported by the horizontal plane of the limiting channel 41, and one side of the connecting part is restricted by the limiting surface of the limiting channel 41, thereby ensuring that the miniature product is continuously restricted within the positioning hole of the product positioning mold 231.

[0069] See Figure 1 , Figures 8 to 12 The processing station is equipped with a processing positioning module 5, which is used to fix the micro product to be processed that arrives and stops at the processing station and to process it. The processing positioning module 5 includes a first positioning mechanism 51 for elastically pressing the upper surface of the micro product, a second positioning mechanism 53 for positioning the side of the connecting part of the micro product, and a processing mechanism 52 for processing the hole of the micro product.

[0070] The machining mechanism 52 includes a machining tool 521 and a machining drive unit 522 for driving the machining tool 521 to lift and rotate. The machining tool can be replaced according to production needs, such as a milling cutter, a thread cutter, a chamfering cutter, etc.

[0071] Furthermore, the first positioning mechanism 51 is supported on the upper part of the turntable 23 by a connecting frame 511. One end of the connecting frame 511 is fixed to the limiting module 4, and the other end extends across the limiting flow channel 41 to the top of the turntable 23, maintaining a certain distance from the upper surface of the turntable to avoid motion interference between the first positioning mechanism 51 and the turntable. The first positioning mechanism 51 uses a return spring 515 to generate elastic pressure on the movable block 514, thereby causing the pressure block 516 to generate elastic pressure on the upper surface of the micro product, preventing damage to the surface of the micro product.

[0072] Specifically, one end of the movable block 514 is connected to the piston rod of the lifting cylinder 513 via the connector 5131, and the other end passes through the positioning block 512 and connects to the pressure block 516. At the same time, the movable block 514 has an up-and-down movement reset gap 517 relative to the positioning block 512, which provides reset space for the reset spring 515.

[0073] That is, during the initial stroke of the lifting cylinder 513, the return spring 515 generates a spring force on the movable block 514 (at this time, the lifting cylinder 513 has no force on the pressure block 516, which can also be understood as the pressure block 516 not contacting the miniature product if the return spring 515 is not set here), so that the pressure block 516 presses onto the miniature product under the action of the spring force; then the lifting stroke of the lifting cylinder 513 is set, and the turntable 23 carries the miniature product on the product positioning mold 231 to the processing station once, and the lifting cylinder 513 drives the movable block 514 to lift once.

[0074] Furthermore, the second positioning mechanism 53 is located on the outside of the limiting module 4, and the limiting module 4 also includes a guide groove 42 arranged radially along the turntable 23 and communicating with the limiting flow channel 41.

[0075] The second positioning mechanism 53 includes a positioning pin 531 slidably connected to the guide groove 42 and a positioning cylinder 532 pulsatorically connected to the positioning pin 531. The positioning cylinder 532 drives the positioning pin 531 to reciprocate within the guide groove 42, causing the end of the positioning pin 531 to be inserted into the product positioning mold 231 to fix the circumference of the micro-product to be processed, or to drive the end of the positioning pin 531 away from the micro-product after processing is completed. The end of the positioning pin 531 is adapted to the connecting part 103 of the micro-product. When the end of the positioning pin 531 is inserted into the positioning hole of the product positioning mold 231, the turntable 23 is stopped and awaits processing by the processing mechanism 52. See also... Figure 1 A pneumatic blowpipe is installed next to the second positioning mechanism 53 of the processing station to blow away and clean the debris generated during processing.

[0076] Meanwhile, the positioning pin 531 and the piston rod of the positioning cylinder 532 are connected by a connecting piece 533. The connecting piece 533 has an installation groove, and the positioning pin 531 can be detachably installed in the installation groove. Therefore, the corresponding positioning pin can be replaced according to the model of the micro product.

[0077] participate Figure 11 The positioning hole of the product positioning mold 231, the pressure block 516 of the first positioning mechanism 51, the end of the positioning pin 531 of the second positioning mechanism 53, and the limiting flow channel 41 of the limiting module 4 limit and fix the micro product in the circumferential direction and the upper and lower end faces, thereby ensuring that the micro product will not shake or rotate during processing and ensuring processing quality.

[0078] See Figure 13On the workbench 1, a unloading station is set on the opposite side of the loading station surrounding the turntable. The unloading station is equipped with an unloading mechanism 62. The unloading mechanism 62 includes a unloading push rod 621 vertically mounted on the turntable 23, and a lifting cylinder 622 for driving the unloading push rod 621 to rise and fall. The lifting cylinder 622 drives the unloading push rod 621 to push the miniature products that have been processed on the product positioning mold 231 directly below the unloading push rod 621 into the guide trough 61. One end of the guide trough 61 is connected to the limiting flow channel 41 of the limiting module 4, and the other end passes directly below the unloading mechanism 62 and extends to the outside of the workbench 1. A receiving bin 63, connected to the guide trough 61, is provided on the second platform 12 to collect the processed miniature products.

[0079] In summary, the operation process of this invention is as follows:

[0080] Initial state: The micro product to be processed is placed in the vibratory feeder 31, the appropriate processing tool 521 is selected and loaded on the processing drive unit 522, the material distribution groove 3311 of the material distribution rod 331 is connected to the conveying channel 32, the receiving bin 63 is placed on the second platform 12, the positioning hole of one of the product positioning molds 231 on the turntable 23 is connected to the pushing channel 352, and the pressure block 516 is away from the limiting channel 41;

[0081] Step 1: Turn on the power and air supply of the control module 8. The vibratory plate 31 vibrates, causing the miniature products inside to enter and be arranged in the conveying channel 32 in sequence. One miniature product at the outlet of the conveying channel 32 enters the material distribution groove 3311. The material distribution cylinder 332 drives the material distribution rod 331 to move to the side of the push channel 352 and stops when the material distribution groove 3311 runs to the front of the push rod 341. Then, the push rod 342 drives the push rod 341 to push the miniature product into the positioning hole of the product positioning mold 231 waiting at the loading station. The push rod 341 resets, the material distribution rod 331 resets, and the above actions are repeated to complete the loading of miniature products one by one.

[0082] Step 2: The turntable rotates, causing the miniature product from Step 1 to arrive at and stop at the processing station. The lifting cylinder 513 drives the movable block 514 to move the pressure block 516 downward, so that the lower end face of the pressure block 516 presses against the upper end face of the miniature product. The positioning cylinder 532 drives the end of the positioning pin 531 to insert into the positioning hole of the product positioning mold 231.

[0083] Step 3: The machining drive unit 522 drives the machining tool 521 to approach the miniature product from step 2 and machine it. After machining is completed, the machining tool is driven to reset, and then the pressure block 516 resets and the positioning pin 531 is positioned.

[0084] Step 4: The turntable rotates, causing the miniature product that has been processed in Step 3 to arrive at and stop at the unloading station. The lifting cylinder 622 drives the unloading push rod 621 to move down and push the miniature product stuck on the product positioning mold 23 onto the guide groove 61, and then slides into the receiving bin 63.

[0085] Step 5: The turntable rotates so that the surface of the unloaded product positioning mold 23 is cleaned by the cleaning component when it passes the cleaning assembly 7.

[0086] Repeat the above steps. Each time the turntable rotates, loading, processing, unloading, and cleaning are carried out simultaneously, realizing fully automated processing of micro products.

[0087] In summary, the micro-product continuous automatic processing equipment provided by this invention achieves fully automated processing of micro-products through a feeding module, a limiting module, a processing positioning module, a unloading module, and a cleaning module arranged around the turntable module. The equipment has a compact overall structure, short product transfer distances between modules, and high processing efficiency. By installing bearings on the divider of the turntable module, the accuracy of the turntable is ensured and the service life of the divider is improved. By setting up a staggered feeding mechanism, the operation of the turntable and the feeding mechanism is ensured to be aligned, while preventing material congestion and jamming during the feeding process, thus ensuring the stability of the feeding process. Through the cooperation of the product positioning module, the first positioning mechanism, the second positioning mechanism, and the limiting module, the circumferential and upper and lower end faces of the material are limited and fixed, thereby ensuring that the material does not shake or rotate during processing, ensuring processing quality.
