Description

Technical Field

[0001] This invention belongs to the field of PCB lamination equipment, specifically an automatic FPC lamination device. Background Technology

[0002] In the SMT (Surface Mount Technology) industry, FPC (Flexible Printed Circuit) flexible circuit board manufacturing processes involve multi-panel assembly. Before cutting the FPC board, critical components need to be positioned and protected by applying PSA (Platelet-Rich Adhesive) adhesive. During the manufacturing process, it's crucial to ensure the PSA adhesive is effectively activated during application and that appropriate pressure is applied to prevent adhesive overflow.

[0003] Currently, the common industry practice is to use two upper and lower molds to apply pressure to the FPC to activate the PSA adhesive, employing a one-piece lamination method. However, this method can lead to uneven PSA adhesive application due to manufacturing precision errors in the mold and cumulative errors in mold installation. This can result in some parts of the FPC not receiving the standard PSA adhesive pressure, leading to either unactivated PSA adhesive or excessive pressure causing adhesive overflow, both of which negatively impact product quality. Furthermore, if a pressure head on the mold is damaged, the entire lamination mold needs to be replaced, which is costly and time-consuming to adjust. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide an automatic FPC pressing device that solves the issues of uneven and unstable FPC lamination with PSA adhesive, as well as the complexity of manual mold installation and maintenance. The device includes an upper cover, a lower frame, and internal components of the frame. The internal components of the frame include a width adjustment track, a stop assembly, a lower mold lifting assembly, and an upper mold pressing assembly. The width adjustment track is located in the center of the device and installed in the large plate of the device. The stop assembly is located at the entrance and exit of the width adjustment track. The lower mold lifting assembly is located below the large plate of the device. The upper mold pressing assembly is located directly above the lower mold lifting assembly and the width adjustment track.

[0005] The width-adjusting track includes an aluminum profile, a first linear guide rail, a lead screw, a first stepper motor, a stepper motor mount, a synchronous pulley, a synchronous belt, a support bearing mount, a first lead screw nut, a pulling plate, a slide cylinder, a second stepper motor, a stepper motor adjustment mount, a drive wheel, a pulley, a flat belt, a limit bearing, and a photoelectric sensor.

[0006] The stop assembly includes a third stepper motor, a motor mounting base, gears, a rack, a second linear guide rail, a limiting urethane rubber, a first photoelectric sensor, a gear and rack module base, a first slotted switch, a blocking cylinder fixing block, a rotary clamping cylinder, and a blocking block.

[0007] The lower mold lifting assembly includes a first servo motor, a first reducer, a first reducer fixing plate, a first coupling, a first reducer support plate, a lower mold fixing plate, a bearing chamber, a first ball screw, a first support column, a linear bearing, a first moving plate, a first moving guide rod, a second screw nut, a second slotted switch, a photoelectric fixing seat, a second photoelectric sensor, a lower mold upper fixing plate, a transition plate, a heat insulation plate, a lifting carrier plate, a heating fixing plate, a second support column, a cold pressing mold fixing plate, and a positioning pin;

[0008] The upper mold pressing assembly includes a second servo motor, a second reducer, a second reducer fixing plate, a second reducer support plate, a second coupling, a lead screw fixing seat, a second ball screw, a first upper mold fixing plate, a third lead screw nut, a third support column, a second moving plate, an upper mold large plate, a second moving guide rod, a second upper mold fixing plate, a PSA upper mold fixing plate, an upper mold fixing plate mounting strip, a PSA upper mold pressure head, a fourth support column, and a CCD assembly.

[0009] Preferably, the upper protective cover is also provided with a human-machine interface and a viewing window for the equipment cover.

[0010] Preferably, the width-adjusting track is constructed from aluminum profiles. Pulleys and drive wheels are installed on the inner sides of both aluminum profiles. A flat belt is wound around the pulleys. The drive wheel is connected to a second stepper motor. The second stepper motor is mounted on the aluminum profile via a stepper motor adjustment seat. The rotation of the second stepper motor drives the flat belt to move, thus moving the product. The aluminum profile is mounted on a first linear guide rail, and a first lead screw nut is connected to the aluminum profile. One end of the lead screw is mounted on a support bearing seat, and the end of the lead screw shaft is connected to a synchronous pulley. The synchronous belt is wound around the synchronous pulley. Another synchronous pulley is connected to a first stepper motor. The first stepper motor is fixed to the equipment plate via a stepper motor seat. The first stepper motor lead screw module drives the aluminum profile to move on the first linear guide rail, achieving automatic width adjustment. A limit bearing is installed above the flat belt. A slide cylinder is installed on the outer side of the aluminum profile, and a pulling plate is installed above it. Photoelectric sensors are installed at both ends of the aluminum profile to detect the inflow and outflow of products.

[0011] Preferably, the bottom of the stop assembly is a gear and rack module base, on which a second linear guide rail, a limiting urethane rubber, a rack, and a first slotted switch are sequentially installed. A motor mounting base is installed on the slider of the second linear guide rail. The third stepper motor is installed above the motor mounting base, and its motor shaft mates with the gear hole and is fixed by a set screw. The gear meshes with the rack, and a first photoelectric sensor is installed on the rack. A blocking cylinder fixing block is installed on the side of the motor mounting base, and a rotary clamping cylinder is installed above it. The rotary clamping cylinder is connected to the blocking block. When the third stepper motor is driven, the motor shaft drives the gear to rotate, and through the gear and rack module, the third stepper motor and the rotary clamping cylinder move linearly on the second linear guide rail, realizing the forward and backward movement of the blocking block. At the same time, the rotary clamping cylinder can raise and lower the blocking block through air pressure.

[0012] Preferably, the lower mold lifting assembly is driven by a first servo motor in conjunction with a first ball screw, and transmitted via linear bearings, to realize the up-and-down movement of the cold pressing mold fixing plate. The first servo motor and the first reducer are mounted on a first reducer fixing plate and fixed to the lower mold fixing plate via the first reducer fixing plate and the first reducer support plate. The first reducer fixing plate is connected to the first ball screw via a first coupling. One end of the first ball screw is fixed to the lower mold fixing plate via a bearing housing, and the other end is fixed to the upper mold fixing plate. A second screw nut is installed in the first ball screw and connected to the first moving plate. The upper mold fixing plate is connected to the lower mold fixing plate via a first support column. The first support column is equipped with a linear bearing. The movable plate is connected to the linear bearing. The adapter plate is connected to the first movable plate via the first movable guide rod. A heat insulation plate, a lifting plate, a heating fixing plate, a second support column, and a cold pressing mold fixing plate are installed on the top of the adapter plate in sequence. The cold pressing mold fixing plate has a hole locking pin. When the first servo motor rotates, the first ball screw connected to it will also rotate, thereby driving the second screw nut to make linear motion on the first ball screw. At this time, the first movable plate connected to the second screw nut drives the linear bearing to slide on the first support column. Since the cold pressing mold fixing plate is actually connected to the first movable plate, the up and down movement of the cold pressing mold fixing plate is realized. The side of the first movable plate is also provided with a photoelectric fixing seat. The photoelectric fixing seat is provided with a second photoelectric sensor and a second slotted switch.

[0013] Preferably, the second servo motor and the second reducer are mounted in the second reducer fixing plate. The second reducer fixing plate is fixed to the first upper mold fixing plate by two second reducer support plates. The second reducer shaft is connected to the second ball screw through a second coupling. One end of the second ball screw is mounted on the first upper mold fixing plate through a screw fixing seat, and the other end is fixed to the upper mold plate. The third screw nut is connected to the second movable plate. Simultaneously, one side of the upper mold plate is connected to the second upper mold fixing plate by four third support columns, and the other side is fixed to the equipment plate by four fourth support columns. The two movable plates are connected to the second upper mold fixing plate through the upper mold plate by six second movable guide rods. The PSA upper mold fixing plate and the upper mold fixing plate mounting strip are installed below the second upper mold fixing plate. The PSA upper mold pressure head is installed below the PSA upper mold fixing plate. A CCD component is also installed on the side of the upper mold plate. When the second servo motor drives, the second ball screw rotates and drives the third screw nut to roll on the second ball screw, which drives the second movable plate to move up and down. Since the upper mold fixing plate, the PSA upper mold fixing plate, the PSA upper mold pressure head and the second movable plate are connected as one unit, the PSA upper mold pressure head moves up and down.

[0014] Preferably, the PSA upper mold head includes a sliding fixed plate, a third linear guide rail, a pressure gauge, a mold head slider fixing plate, and a PSA silicone mold head. The third linear guide rail and the pressure gauge are installed inside the sliding fixed plate. The mold head slider fixing plate is installed on the third linear guide rail, and the PSA silicone mold head is installed below the mold head slider fixing plate.

[0015] The beneficial effects of this invention are as follows: Addressing the aforementioned problems, compared to traditional FPC pressing processes, this equipment achieves fully automated online pressing. By controlling the pressing effect at a single point, it avoids poor pressing caused by flatness issues and pressing point position errors. Simultaneously, it saves labor costs and reduces maintenance difficulty, significantly improving production efficiency. This equipment uses a width-adjustable track to input the product to the corresponding position, with a stop mechanism for front and rear positioning. The lower mold lifting component begins lifting, and then the upper mold pressing component presses the product. After pressing, the product automatically flows to the next process, achieving fully automated online pressing. This avoids poor pressing caused by positional errors resulting from manual product placement, while also saving labor costs and significantly improving production efficiency. Furthermore, the equipment structure has the following advantages:

[0016] 1. The main body of the adjustable track is made of aluminum profile, which is lightweight, easy to process, and low in cost;

[0017] 2. The bottom of the width-adjusting track is installed on the first linear guide rail, and the side is connected to the first lead screw nut. It is driven by the first stepper motor, and the synchronous belt and synchronous pulley drive the lead screw to make linear motion, thereby moving the track to both sides to achieve the purpose of width adjustment. It realizes automatic width adjustment and is compatible with products of different specifications.

[0018] 3. This equipment uses photoelectric sensors to detect incoming products. The bearings on both sides of the track act as guides and prevent the products from deviating to the left or right (the structure is low-cost, and the limit bearings also act as guides to prevent products from getting stuck on the track and reducing production capacity).

[0019] 4. The front and rear stop structures of the adjustable track achieve the center positioning of the product in the front and rear directions by driving the rotary cylinder through the gear and rack. This positioning method is simple and compact, which greatly saves product space.

[0020] 5. The lower mold lifting component is installed with positioning pins that are inserted into the corresponding holes of the product to ensure the positional accuracy of the product during pressing. At the same time, the pin holes and pins provide high positioning accuracy and are easy and inexpensive to process.

[0021] 6. The PSA molding head is equipped with a pressure gauge. The pressure range can be set according to the pressure value required for product pressing. When the pressing pressure exceeds or falls below the range, an alarm will be triggered automatically to prevent product defects.

[0022] 7. The layered design of the upper and lower mold structure saves equipment space while ensuring the positioning accuracy of the product and guaranteeing the product pressing yield. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0038] like Figure 1-7 As shown, the present invention provides an automatic FPC pressing device that solves the problems of high misjudgment rate and poor installation during manual operation. The device includes an upper protective cover 11, a lower frame 15, and internal components of the frame. The internal components of the frame include a width-adjusting track 16, a stop assembly 17, a lower mold lifting assembly 18, and an upper mold pressing assembly 19. The width-adjusting track 16 is located in the center of the device and installed in the large plate of the device. The stop assembly 17 is located at the entrance and exit of the width-adjusting track 16. The lower mold lifting assembly 18 is located below the large plate of the device. The upper mold pressing assembly 19 is located directly above the lower mold lifting assembly 18 and the width-adjusting track 16.

[0039] The width-adjusting track 16 includes an aluminum profile 16-1, a first linear guide rail 16-2, a lead screw 16-3, a first stepper motor 16-4, a stepper motor mount 16-5, a synchronous pulley 16-6, a synchronous belt 16-7, a support bearing mount 16-8, a first lead screw nut 16-9, a pulling plate 16-10, a slide cylinder 16-11, a second stepper motor 16-12, a stepper motor adjusting mount 16-13, a drive wheel 16-14, a pulley 16-15, a flat belt 16-16, a limit bearing 16-17, and a photoelectric sensor 16-18.

[0040] Specifically, the main body of the width-adjusting track 16 is constructed from aluminum profiles 16-1. Pulleys 16-15 and drive pulleys 16-14 are installed on the inner sides of both aluminum profiles 16-1. A flat belt 16-16 is wound around the pulleys 16-15. The drive pulley 16-14 is connected to the second stepper motor 16-12. The second stepper motor 16-12 is mounted on the aluminum profiles 16-1 via a stepper motor adjustment seat 16-13. The rotational movement of the second stepper motor 16-12 drives the flat belt 16-16 to move, thus achieving product movement. The aluminum profiles 16-1 are mounted on the first linear guide rail 16-2. Simultaneously, the first lead screw nut 16-9 is connected to the aluminum profiles 16-1. One end of the lead screw 16-3 is mounted on the support bearing seat 16-8, and the end of the lead screw 16-3 shaft is connected to the synchronous pulley 16-6. The synchronous belt 16- 7 is wound around the synchronous pulley 16-6. Another synchronous pulley 16-6 is connected to the first stepper motor 16-4. The first stepper motor 16-4 is fixed to the equipment plate through the stepper motor seat 16-5. The aluminum profile 16-1 is driven to move on the first linear guide rail 16-2 through the lead screw module of the first stepper motor 16-4 to achieve automatic width adjustment and accommodate different product sizes. A limit bearing 16-17 is installed above the flat belt 16-16 to prevent the product from running to the left or right while pressing the belt. A slide cylinder 16-11 is installed on the outside of the aluminum profile 16-1, and a pulling plate 16-10 is installed above it. The product is then pressed flat so that the product mounting hole is installed in the positioning pin 18-24 of the lower mold lifting assembly 18. At the same time, photoelectric sensors 16-18 are installed at both ends of the aluminum profile 16-1 to detect the inflow and outflow of the product.

[0041] The stop assembly 17 includes a third stepper motor 17-1, a motor mounting base 17-2, a gear 17-3, a rack 17-4, a second linear guide rail 17-5, a limiting urethane rubber 17-6, a first photoelectric sensor 17-7, a gear and rack module base 17-8, a first slotted switch 17-9, a blocking cylinder fixing block 17-10, a rotary clamping cylinder 17-11, and a blocking block 17-12;

[0042] Specifically, the bottom of the stop assembly 17 is a gear and rack module base 17-8, on which a second linear guide rail 17-5, a limiting urethane rubber 17-6, a rack 17-4, and a first slotted switch 17-9 are sequentially mounted. A motor mounting base 17-2 is mounted on the slider of the second linear guide rail 17-5. A third stepper motor 17-1 is mounted above the motor mounting base 17-2, and its motor shaft mates with the hole of the gear 17-3 and is fixed by a set screw. The gear 17-3 meshes with the rack 17-4, and a first photoelectric sensor 17-7 is mounted on the rack 17-4. The motor mounting base 17-8... 2. A blocking cylinder fixing block 17-10 is installed on the side, and a rotary clamping cylinder 17-11 is installed above it. The rotary clamping cylinder 17-11 is connected to the blocking block 17-12. When the third stepper motor 17-1 is driven, the motor shaft drives the gear 17-3 to rotate. Through the gear and rack module, the third stepper motor 17-1 and the rotary clamping cylinder 17-11 move linearly together on the second linear guide rail 17-5, realizing the forward and backward movement of the blocking block 17-12. At the same time, the rotary clamping cylinder 17-11 can realize the rise and fall of the blocking block 17-12 through air pressure.

[0043] The lower mold lifting assembly 18 includes a first servo motor 18-1, a first reducer 18-2, a first reducer fixing plate 18-3, a first coupling 18-4, a first reducer support plate 18-5, a lower mold fixing plate 18-6, a bearing chamber 18-7, a first ball screw 18-8, a first support column 18-9, a linear bearing 18-10, a first moving plate 18-11, a first moving guide rod 18-12, a second screw nut 18-13, a second slotted switch 18-14, a photoelectric fixing seat 18-15, a second photoelectric sensor 18-16, a lower mold upper fixing plate 18-17, a transition plate 18-18, a heat insulation plate 18-19, a lifting carrier plate 18-20, a heating fixing plate 18-21, a second support column 18-22, a cold pressing mold fixing plate 18-23, and a positioning pin 18-24.

[0044] Specifically, the lower mold lifting assembly 18 is driven by a first servo motor 18-1 in conjunction with a first ball screw 18-8, and transmitted by a linear bearing 18-10, realizing the up and down movement of the cold pressing mold fixing plate 18-23. The first servo motor 18-1 and the first reducer 18-2 are mounted on the first reducer fixing plate 18-3, and are fixed to the lower mold fixing plate 18-6 through the first reducer fixing plate 18-3 and the first reducer support plate 18-5. The first reducer fixing plate 18-3 is connected to the first ball screw 18-8 via the first coupling 18-4. The first ball screw 18-8 is connected to the lower die fixing plate 18-6 via a bearing housing 18-7 at one end and the upper die fixing plate 18-17 at the other end. A second screw nut 18-13 is installed in the first ball screw 18-8 and connected to the first moving plate 18-11. The upper die fixing plate 18-17 is connected to the lower die fixing plate 18-6 via a first support column 18-9. A linear bearing 18-10 is installed in the first support column 18-9. The first moving plate 18-11 is connected to the linear bearing 18-10. 0 connection, the adapter plate 18-18 is connected to the first moving plate 18-11 via the first moving guide rod 18-12, and the heat insulation plate 18-19, the lifting plate 18-20, the heating fixing plate 18-21, the second support column 18-22 and the cold pressing mold fixing plate 18-23 are installed on it in sequence. The cold pressing mold fixing plate 18-23 has a hole locking pin 18-24. When the first servo motor 18-1 rotates, the first ball screw 18-8 connected to it will also rotate, thereby driving the second screw nut 18-13 on the first ball screw The first moving plate 18-11, which is connected to the second lead screw nut 18-13, moves linearly. At this time, the first moving plate 18-11 drives the linear bearing 18-10 to slide on the first support column 18-9. Since the cold pressing mold fixing plate 18-23 is actually connected to the first moving plate 18-11, the cold pressing mold fixing plate 18-23 can move up and down. The side of the first moving plate 18-11 is also provided with a photoelectric fixing seat 18-15. The photoelectric fixing seat 18-15 is provided with a second photoelectric sensor 18-16 and a second slotted switch 18-14.

[0045] The upper mold pressing assembly 19 includes a second servo motor 19-1, a second reducer 19-2, a second reducer fixing plate 19-3, a second reducer support plate 19-4, a second coupling 19-5, a lead screw fixing seat 19-6, a second ball screw 19-7, a first upper mold fixing plate 19-8, a third lead screw nut 19-9, a third support column 19-10, a second moving plate 19-11, an upper mold large plate 19-12, a second moving guide rod 19-13, a second upper mold fixing plate 19-14, a PSA upper mold fixing plate 19-15, an upper mold fixing plate mounting strip 19-16, a PSA upper mold pressure head 19-17, a fourth support column 19-18, and a CCD assembly 19-19.

[0046] Specifically, the second servo motor 19-1 and the second reducer 19-2 are installed in the second reducer fixing plate 19-3. The second reducer fixing plate 19-3 is fixed to the first upper mold fixing plate 19-8 by two second reducer support plates 19-4. The shaft of the second reducer 19-2 is connected to the second ball screw 19-7 through the second coupling 19-5. One end of the second ball screw 19-7 is installed on the first upper mold fixing plate 19-8 through the screw fixing seat 19-6, and the other end is fixed to the upper mold plate 19-12. The third screw nut 19-9 is connected to the second moving plate 19-11. At the same time, one side of the upper mold plate 19-12 is connected to the second upper mold fixing plate 19-14 through four third support columns 19-10, and the other side is fixed to the equipment plate through four fourth support columns 19-18. The second moving plate 19-11 is connected to the second upper mold fixing plate 19-14 through six second support columns 19-10. The movable guide rod 19-13 passes through the upper mold plate 19-12 and connects to the second upper mold fixing plate 19-14. The PSA upper mold fixing plate 19-15 and the upper mold fixing plate mounting strip 19-16 are installed below the second upper mold fixing plate 19-14. The PSA upper mold pressure head 19-17 is installed below the PSA upper mold fixing plate 19-15. The CCD component 19-19 is also installed on the side of the upper mold plate 19-12. When the second servo motor 19-1 drives, the second ball screw 19-7 rotates, causing the third screw nut 19-9 to roll on the second ball screw 19-7, which in turn causes the second movable plate 19-11 to move up and down. Since the second upper mold fixing plate 19-14, the PSA upper mold fixing plate 19-15, the PSA upper mold pressure head 19-17 and the second movable plate 19-11 are connected as one unit, the PSA upper mold pressure head 19-17 moves up and down.

[0047] Specifically, the PSA upper mold head 19-17 includes a sliding fixing plate 19-17-1, a third linear guide rail 19-17-2, a pressure gauge 19-17-3, a head slider fixing plate 19-17-4, and a PSA silicone head 19-17-5. The third linear guide rail 19-17-2 and the pressure gauge 19-17-3 are installed inside the sliding fixing plate 19-17-1. The head slider fixing plate 19-17-4 is installed on the third linear guide rail 19-17-2, and the PSA silicone head 19-17-5 is installed below the head slider fixing plate 19-17-4.

[0048] The PSA upper molding head 19-17 can perform both cold and hot pressing. It uses a PSA silicone molding head 19-17-5, which better protects the product and will not damage the product surface. The hot pressing uses five temperature sensors, one at each of the four corners and the middle position, which is more accurate and stable than a single temperature sensor.

[0049] In addition, each PSA upper die head 19-17 is equipped with a pressure sensor. The pressure is fed back to the sensor through the deformation of the compression spring. This allows for accurate understanding of the pressure position, improving yield and increasing production efficiency. The slide rails use the HIWIN brand, and the pressure sensors are imported from Germany, which have the advantages of high quality and high precision compared to domestic products.

[0050] Specifically, the upper protective cover 11 is also provided with a human-machine interface 12 and a device protective cover viewing window 13.

[0051] In this invention, the device operation process is as follows:

[0052] 1. Product inflow:

[0053] Product delivery Figure 2 In the width adjustment track 16, the photoelectric sensor 16-18 detects the product flowing in, and the second stepper motor 16-12 starts to drive, driving the synchronous pulley 16-6 to rotate, thereby driving the flat belt 16-16 to drive the product to move in a straight line and transport the product to the pressing area (the limit bearing 16-17 in the width adjustment track 16 plays a guiding role to prevent the product from deviating in the left and right directions).

[0054] 2. Vehicle forward and backward positioning:

[0055] When the motor of the width-adjusting track 16 stops moving, the stop mechanisms 17 on the front and rear sides first drive the blocking block 17-12 to rise through the rotary clamping cylinder 17-11, and then drive the gear rack through the third stepper motor 17-1 to move the blocking block 17-12 forward to push the product. The stop mechanisms 17 at the front and rear ends of the product move at the same time to achieve center positioning of the product in the front and rear directions.

[0056] 3. Product lifting:

[0057] The first servo motor 18-1 of the lower mold lifting assembly 18 drives the cold pressing mold fixing plate 18-23 to move upward through the first ball screw 18-8. The positioning pin 18-24 on the cold pressing mold fixing plate 18-23 passes through the corresponding hole of the product and continues to lift, so that the product is separated from the belt and placed flat on the cold pressing mold fixing plate 18-23. At this time, the pulling plate 16-10 mounted on the slide cylinder 16-11 slides downward to press the product, so that it is completely attached and fixed to the cold pressing mold fixing plate 18-23.

[0058] 4. Product pressing:

[0059] The second servo motor 19-1 of the upper mold pressing assembly 19 drives the PSA upper mold pressing head 19-17 to move downwards through the second ball screw 19-7 until it presses down on the corresponding position of the product and holds pressure to achieve complete pressing (the PSA upper mold pressing head 19-17 is equipped with a miniature tension and compression sensor that can read the pressure value at the corresponding point. When the pressure exceeds the specified range, it will automatically alarm to avoid producing a large number of defective products).

[0060] 5. Product outflow:

[0061] The second servo motor 19-1 of the upper mold pressing assembly 19 drives the PSA upper mold pressing head 19-17 to move upward and reset via the second ball screw 19-7. The stop mechanism 17 first drives the gear rack via the third stepper motor 17-1 to move the blocking block 17-12 backward away from the product, and then drives the blocking block 17-12 to reset via the rotary clamping cylinder 17-11. The first servo motor 18-1 of the lower mold lifting assembly 18 drives the cold pressing mold fixing plate 18-23 downward via the first ball screw 18-8, so that the product is placed flat again in the flat belt 16-16 of the width adjustment track 16. The lower mold lifting assembly 18 continues to descend and completely detaches from the product before resetting. At this time, the second slotted switch 18-14 senses that the second photoelectric sensor 18-16 has returned to the origin, the first servo motor 18-1 stops, and the second stepper motor 16-12 of the width adjustment track 16 starts to drive the product into the next process.
