Description

Technical Field

[0001] The present invention relates to the technical field of cold pressing processing of copper clad laminates, and in particular to a cold pressing processing device and a processing method of a copper clad laminate for a new energy vehicle charging pile. Background Art

[0002] Copper clad laminate is a basic material for the electronics industry. It is used to process and manufacture printed circuit boards and is widely used in electronic products such as new energy charging piles and computers. In new energy charging piles, copper clad laminates are usually used to connect various electronic components. During the cold pressing process of copper clad laminates, pressure is applied to make the copper clad laminates plastically deform under the action of the mold to obtain the desired shape and size. During the cold pressing process of copper clad laminates, the copper clad laminates are subjected to the pressure of the pressure head, and the material on the surface of the copper clad laminates will peel off to form debris. Therefore, during the cold pressing process of copper clad laminates, the handling of debris is crucial to improving production efficiency and reducing labor intensity.

[0003] These debris will adhere to the mold groove of the lower mold and the surface of the upper mold. After the processing is completed, the workpiece needs to be manually removed, and then manually cleaned or vacuumed to clean the debris in the mold groove and on the surface of the upper mold. Only after cleaning can subsequent loading operations be performed; during this process, the equipment cannot perform processing operations, and the debris cannot be cleaned synchronously from the lower mold and the upper mold through manual cleaning or vacuuming equipment during the cleaning process, which not only increases the workload of the staff, but also prolongs the cleaning time during the cleaning process, greatly reducing the efficiency of cold pressing processing.

[0017] A cold pressing method for a copper-clad plate for a new energy vehicle charging pile includes the following steps:

[0018] Step 1: The rotating disc drives a lower die seat to rotate to the loading area for loading. After loading, the rotating disc drives the lower die seat with the copper-clad laminate to rotate to the cold pressing area. The copper-clad laminate is cold pressed by closing the upper die seat with the lower die seat. After cold pressing, the stamping cylinder drives the upper die seat to move upward to the top for reset, and then the debris attached to the lower end of the upper die seat is cleaned by the cleaning mechanism;

[0019] Step 2: The rotating disc drives the cold-pressed copper-clad laminate and the lower die seat to rotate to the flipping and unloading area, so that the locking crown gear in the locking mechanism is separated from the rotating crown gear, and the transmission head is engaged with the docking groove on the side of the docking head. The output shaft of the second stepper motor in the flipping and unloading area rotates by half a circle, so that the mold cavity of the lower die seat is flipped to face downward, and the demoulding mechanism at the lower end of the lower die seat is flipped to the top;

[0020] Step 3: The rotating disc drives the flipped lower die base to rotate from the flipping and unloading area to the return area, and the fan-shaped limit plate pushes the demoulding mechanism to move downward, and pushes the cold-pressed copper-clad laminate in the mold cavity of the lower die base downward, thereby demoulding and unloading. At the same time, the blower mechanism cleans the debris on the inner wall of the mold cavity of the lower die base;

[0021] Step 4: Rotate the cleaned lower die base to the return area by rotating the disc, rotate the output shaft of the second stepper motor in the return area by half a circle, so that the cavity opening of the lower die base faces upward, and finally rotate the returned lower die base to the loading area by rotating the disc for loading. The loading area, cold pressing area, flipping and unloading area and return area in four areas can operate at the same time, and the reciprocating cycle operation can continuously load the copper clad laminate, cold press and unload, and clean the upper and lower die bases.

[0022] The beneficial effects of the present invention are:

[0023] 1. The top of the support table is in a circular array, which consists of four areas: loading area, cold pressing area, flipping and unloading area, and return area. The loading area, cold pressing area, flipping and unloading area, and return area in the four areas can operate simultaneously without interfering with each other. That is, the loading area can load the copper-clad sheet into the inner cavity of a lower die seat, the cold pressing area can cold press the copper-clad sheet in a lower die seat, the flipping and unloading area can unload the copper-clad sheet after cold pressing, and the return area can return the lower die seat after unloading and cleaning. Such reciprocating operation greatly improves the work efficiency.

[0024] 2. When the rotating disc drives a lower die seat to rotate to the loading area first for loading; rotate to the cold pressing area to cold press the copper clad laminate; rotate to the flipping unloading area, so that the cavity opening of the lower die seat equipped with the cold pressed copper clad laminate is downward; when the rotating disc drives the flipped lower die seat to rotate from the flipping unloading area to the return area, the demoulding mechanism is pushed by the fan-shaped limit plate to cooperate with the cold pressed copper clad laminate in the cavity of the lower die seat to demould and unload the copper clad laminate, and the blower mechanism cleans the debris on the inner wall of the cavity of the lower die seat; after rotating to the return area, the cavity opening of the lower die seat is facing upward, and finally the returned lower die seat is rotated to the loading area by the rotating disc to load the material, and the operation is repeated in this way.

[0025] 3. When the lower die base needs to be rotated, the transmission head is engaged with the docking groove on the side of the docking head, and the transmission plate is pushed by the extrusion plate to separate the locking crown gear and the rotating crown gear in the locking mechanism, thereby releasing the lock on the circular shaft; when the lower die base does not need to be flipped, the transmission plate is separated from the extrusion plate, and the locking mechanism locks the circular shaft, making it impossible for the lower die base to rotate.

[0026] 4. The cleaning mechanism can be used to clean the debris on the upper die base. The hair dryer and cleaning brush can be used to clean the debris on the lower die base and the lifting plate. The cleaning process does not require manual operation and will not affect the cold pressing operation of the new copper clad laminate in the cold pressing area, which reduces waiting time and improves work efficiency.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 9 The present invention provides a technical solution: a cold pressing processing device for a copper-clad plate of a new energy vehicle charging pile, comprising a support platform 1, the upper end of the support platform 1 is recessed downward to open a rotating circular groove 11, the bottom of the rotating circular groove 11 is penetrated downward to open a fan-shaped groove 12, and a plurality of cleaning brushes 13 are fixedly installed at equal intervals in the fan-shaped groove 12, the lower end of the support platform 1 is fixedly installed with a supporting leg, the lower end of the cleaning brush 13 is fixedly installed with a convex frame, the convex frame is fixedly installed on the lower end of the support platform 1 by bolts, and a bearing platform 14 is fixedly installed at the bottom of the rotating circular groove 11, the upper end of the support platform 1 is fixedly connected with a concave frame 2 across, the upper end of the concave frame 2 is fixedly installed with a stamping cylinder 21, the lower end of the stamping cylinder 21 is fixedly installed with an upper die seat 22, the bearing platform 14 is arranged directly below the upper die seat 22, a cleaning mechanism is installed on the concave frame 2, and a fan-shaped limiting plate 23 is fixedly installed on the side of the concave frame 2 through a bracket, and a blower mechanism is installed on the fan-shaped limiting plate 23;

[0039] A rotating disc 3 is installed in the rotating circular groove 11, and four flip grooves 32 are opened in a circular array at the upper end of the rotating disc 3. A flippable lower mold base 4 is installed in each flip groove 32. Both sides of the lower mold base 4 are rotatably connected to the flip grooves 32 through circular shafts 41. The circular shaft 41 is fixedly connected to the side of the lower mold base 4. A demoulding mechanism is installed on the lower mold base 4, and a locking mechanism is installed on one side of the lower mold base 4.

[0040] A fan-shaped groove is formed at the upper end of the bearing platform 14, and the upper end of the bearing platform 14 contacts the lower end of the lower die base 4, thereby supporting the lower die base 4. When the lower die base 4 rotates with the rotating disc 3, the lower end of the demoulding mechanism on the lower die base 4 passes through the fan-shaped groove;

[0041] When the punching oil cylinder 21 drives the upper die base 22 to move downward to close the mold with the lower die base 4 to perform cold pressing on the copper clad laminate, the lower die base 4 is supported by the bearing platform 14 .

[0042] See also Figure 2 , Figure 4 and Figure 6 The bottom of the rotating circular groove 11 protrudes upward and is provided with a circular protrusion. The lower end of the rotating disc 3 is in rotational contact with the upper end of the circular protrusion. The lower end of the rotating disc 3 is fixedly connected to a limiting cylinder 31. The limiting cylinder 31 is rotatably connected to the circular protrusion and the support platform 1 respectively. The limiting cylinder 31 is driven by the motor shaft of the first stepper motor fixedly installed at the lower end of the support platform 1.

[0043] Each time the motor shaft of the stepper motor rotates once, the limit cylinder 31 rotates a quarter of a circle, and the limit cylinder 31 drives the rotating disc 3 to rotate a quarter of a circle. Each time the rotating disc 3 stops, there will always be a flip groove 32 directly below the upper die seat 22, so that a lower die seat 4 is directly below the upper die seat 22;

[0044] By rotating the motor shaft of the stepper motor multiple times, multiple lower die seats 4 pass directly under the upper die seat 22 in sequence, thereby completing the cold pressing of the copper-clad plate inside the lower die seat 4, and this reciprocating process can be continuously performed.

[0045] See also Figure 1 and Figure 4 The cleaning mechanism includes a rotating head 221 installed below the concave frame 2, the rotating head 221 is driven by the motor shaft of a servo motor fixedly installed at the upper end of the concave frame 2, a rotating brush 222 is fixedly installed on the side of the rotating head 221, and a material receiving box 223 is fixedly installed at the lower end of the rotating head 221, and the rotating brush 222 is located above the inner cavity of the material receiving box 223.

[0046] When the upper die holder 22 completes a cold pressing process and moves upward to the top, the rotating brush 222 is just at the lower side of the upper die holder 22, but it does not affect the normal lifting and lowering movement of the upper die holder 22;

[0047] The motor shaft of the servo motor drives the rotating head 221 to rotate, and the rotating head 221 drives the rotating brush 222 and the material receiving box 223 to rotate synchronously. When the rotating brush 222 rotates from the bottom of the upper mold base 22, the debris attached to the lower end of the upper mold base 22 is cleaned by the rotating brush 222, and the cleaned debris falls downward into the material receiving box 223 for collection, thereby completing the cleaning of the debris at the lower end of the upper mold base 22;

[0048] When the upper die base 22 is cleaned, the motor shaft of the servo motor stops rotating, thereby stopping the rotating head 221, the rotating brush 222, and the material receiving box 223. At the same time, the stopping position of the rotating brush 222 and the material receiving box 223 is not directly below the upper die base 22, thereby ensuring that the upper die base 22 can be normally raised and lowered for cold pressing operations.

[0049] See also Figure 1 , Figure 2 and Figure 7 A fan-shaped mounting groove is formed through the upper end of the fan-shaped limiting plate 23 downwardly, and the hair dryer mechanism includes an air outlet scoop 24 fixedly installed in the fan-shaped mounting groove. A blower 25 is fixedly installed on the upper end of the concave frame 2. The air outlet end of the blower 25 is connected to one end of the air duct 26 through a pipe joint, and the other end of the air duct 26 is connected to the air inlet end of the air outlet scoop 24 through a pipe joint.

[0050] The air is sent into the air outlet scoop 24 through the air duct 26 by the air outlet fan 25, and the air is blown downward along the air outlet scoop 24, thereby performing a cleaning operation.

[0051] See also Figure 2 , Figure 3 and Fig. 9A circular cleaning groove is provided at the bottom of the mold cavity of the lower mold base 4, and a plurality of inwardly inclined connecting inclined grooves 42 are provided at the bottom of the circular cleaning groove. A vent 43 is provided at the lower end of the lower mold base 4, and the lower ends of the plurality of connecting inclined grooves 42 are all connected to the vent 43;

[0052] One end of the circular shaft 41 on one side of the lower mold base 4 passes through the rotating disc 3 and is fixedly connected to a docking joint 45, one end of which is provided with a docking groove, and two transmission heads 46 are installed on the inner side wall of the rotating circular groove 11. The transmission head 46 is driven by the output shaft of the second stepper motor fixedly installed on the side of the support platform 1, and the transmission head 46 is engaged with the docking groove of the docking joint 45. The rotation axis center lines of the two transmission heads 46 are vertical, and the two transmission heads 46 are arranged on the side above the fan-shaped groove 12.

[0053] When the inner cavity of the lower mold base 4 needs to be cleaned, the lower mold base 4 is first turned over 180 degrees, so that the mold cavity opening of the lower mold base 4 is downward and the opening of the vent 43 is upward. At this time, the air blown downward by the air outlet 24 flows downward along the vent 43, and the air blows obliquely downward along the connecting inclined groove 42 to the zigzag cleaning groove. The air passes through the zigzag cleaning groove and blows downward along the inner wall of the mold cavity, thereby cleaning the debris on the inner wall of the mold cavity of the lower mold base 4.

[0054] When the rotating disc 3 drives the lower die base 4 to rotate to one end of the transmission head 46, the transmission head 46 is engaged with the docking groove of the docking joint 45 at the end of the round shaft 41. At this time, the transmission head 46 is driven by the output shaft of the second stepper motor to rotate half a circle. The transmission head 46 drives the lower die base 4 to rotate half a circle through the docking joint 45 and the round shaft 41, so that the lower die base 4 is flipped one hundred and eighty degrees.

[0055] See also Figure 8 and Fig. 9 The demoulding mechanism includes a lifting plate 5 which is slidably installed at the bottom of the mold cavity of the lower mold base 4. The lower end of the lifting plate 5 is symmetrically fixedly connected with multiple sliding rods 51. The lower ends of the multiple sliding rods 51 penetrate downward through the lower mold base 4 and are fixedly connected to a lifting frame 53. The lower end of each sliding rod 51 is sleeved with a return spring 52.

[0056] The slide rod 51 is connected to the lower die base 4 for sliding up and down movement. A plurality of circular grooves are symmetrically provided at the lower end of the lower die base 4. The slide rod 51 passes through the inner cavity of the circular groove. The upper end of the return spring 52 abuts against the upper end of the circular groove, and the lower end of the return spring 52 abuts against the lifting frame 53.

[0057] A through slot is formed on the inner side of the lifting frame 53, and when the lower die base 4 is cleaned, the wind flows through the through slot;

[0058] Both ends of the bottom of the lifting frame 53 are arc-shaped surfaces. When the lower mold base 4 is turned over 180 degrees, the lifting frame 53 is turned over to the top of the lower mold base 4. At this time, the rotating disc 3 drives the lower mold base 4 and the demoulding mechanism to rotate;

[0059] When the lower die base 4 and the demoulding mechanism rotate to the bottom of the fan-shaped limit plate 23, the fan-shaped limit plate 23 pushes the lifting frame 53 to move downward close to the lower die base 4. At the same time, the lifting frame 53 drives the lifting plate 5 to continue to move downward in the mold cavity through the slide bar 51. The lifting frame 53 squeezes the reset spring 52 to move the lifting plate 5 downward out of the mold cavity, and the cold-pressed copper-clad laminate in the mold cavity of the lower die base 4 is pushed downward by the lifting plate 5, thereby demoulding;

[0060] After demoulding is completed, the lifting plate 5 is continuously outside the mold cavity, and the rotating disc 3 drives the lower mold base 4 and the demoulding mechanism to continue to rotate. When the lifting plate 5 moves over the upper end of the cleaning brush 13, the cleaning brush 13 cleans the debris on the lifting plate 5;

[0061] When the lower mold base 4 and the demoulding mechanism are away from the fan-shaped limiting plate 23 , the lifting frame 53 is reset under the action of the elastic force of the reset spring 52 , so that the lifting plate 5 is retracted into the mold cavity of the lower mold base 4 .

[0062] See also Figure 2 , Figure 3 and Fig. 9 The upper end of the rotating disc 3 is provided with four movable grooves 33 in a circular array, and the four movable grooves 33 are arranged one by one on the outer sides of the four flip grooves 32. The circular shaft 41 on one side of the lower die base 4 passes through the movable groove 33, and the movable groove 33 is symmetrically provided with sliding grooves 34. The locking mechanism includes a rotating crown gear 44 sleeved on the circular shaft 41 and a locking crown gear 6, and the locking crown gear 6 is engaged with the rotating crown gear 44;

[0063] The side of the locking crown gear 6 is symmetrically fixedly connected with a slider 61, the side of the slider 61 is fixedly installed with a locking spring 62, the lower end of the locking crown gear 6 is fixedly connected with a transmission plate 63, and the bottom of the rotating circular groove 11 is fixedly connected with two extrusion plates 64, which are respectively arranged at the lower part of the inner side of the transmission head 46, and the extrusion plates 64 are abutted against the transmission plate 63.

[0064] Both sides of the surfaces where the extrusion plate 64 and the transmission plate 63 approach each other are arranged as slope surfaces.

[0065] The rotating crown gear 44 is fixedly connected to the circular shaft 41 , the locking crown gear 6 is movably sleeved on the circular shaft 41 , the slider 61 is slidably connected to the slide slot 34 , and one side of the locking spring 62 abuts against the inner wall of the slide slot 34 .

[0066] When the lower die base 4 rotates to the inner side of the transmission head 46 along with the rotating disc 3, the transmission plate 63 in the locking mechanism on the side of the lower die base 4 abuts against the extrusion plate 64, and the extrusion plate 64 pushes the transmission plate 63 to move away from the rotating crown gear 44, and the transmission plate 63 drives the locking crown gear 6 to move away from the rotating crown gear 44, so that the locking crown gear 6 is separated from the rotating crown gear 44, and the locking crown gear 6 drives the slider 61 to slide along the slide groove 34, and the slider 61 squeezes the locking spring 62;

[0067] When the locking crown gear 6 is separated from the rotating crown gear 44, the round shaft 41 can rotate; when the lower die base 4 moves away from the transmission head 46 along with the rotating disc 3, the transmission plate 63 in the locking mechanism on the side of the lower die base 4 moves away from the extrusion plate 64. At this time, the slider 61 slides back under the action of the elastic force of the locking spring piece 62, and the slider 61 drives the locking crown gear 6 to engage with the rotating crown gear 44, so that the rotating crown gear 44 cannot rotate. Since the rotating crown gear 44 is fixedly connected to the round shaft 41, the round shaft 41 and the lower die base 4 are also unable to rotate.

[0068] The top of the support table 1 is divided into four areas in a circular array, which are respectively the loading area, the cold pressing area, the turning and unloading area and the return area. The two transmission heads 46 and the two extrusion plates 64 are respectively arranged in the turning and unloading area and the return area, and the fan-shaped groove 12 and the cleaning brush 13 are both arranged between the turning and unloading area and the return area.

[0069] A cold pressing method for a copper-clad plate for a new energy vehicle charging pile includes the following steps:

[0070] Step 1: The rotating disc 3 drives a lower die seat 4 to rotate to the loading area for loading. After loading, the rotating disc 3 drives the lower die seat 4 equipped with the copper-clad laminate to rotate to the cold pressing area, and the copper-clad laminate is cold-pressed by the upper die seat 22 and the lower die seat 4. After cold pressing, the stamping cylinder 21 drives the upper die seat 22 to move upward to the top to reset, and then the debris attached to the lower end of the upper die seat 22 is cleaned by the cleaning mechanism;

[0071] Step 2: The rotating disc 3 drives the cold-pressed copper-clad plate and the lower die seat 4 to rotate to the flipping and unloading area, so that the locking crown gear 6 in the locking mechanism is separated from the rotating crown gear 44, and the transmission head 46 is engaged with the docking groove on the side of the docking head 45. The output shaft of the second stepper motor in the flipping and unloading area rotates by half a circle, so that the mold cavity of the lower die seat 4 is flipped to face downward, and the demoulding mechanism at the lower end of the lower die seat 4 is flipped to the top;

[0072] Step 3: The flipped lower die base 4 is driven to rotate from the flipping and unloading area to the returning area by the rotating disc 3, and the fan-shaped limit plate 23 pushes the demoulding mechanism to move downward, and the cold-pressed copper-clad laminate in the mold cavity of the lower die base 4 is pushed downward, thereby demoulding and unloading. At the same time, the blower mechanism cleans the debris on the inner wall of the mold cavity of the lower die base 4;

[0073] Step 4: Rotate the cleaned lower die base 4 to the return zone by rotating the disc 3, rotate the output shaft of the second stepper motor in the return zone by half a circle, so that the cavity opening of the lower die base 4 faces upward, and finally rotate the returned lower die base 4 to the loading zone by rotating the disc 3 for loading. The loading zone, cold pressing zone, flipping and unloading zone and return zone in the four areas can operate at the same time, and the reciprocating cycle operation can continuously load the copper clad laminate, cold press and unload, and clean the upper and lower die bases.

[0074] Working principle: The rotating disc 3 drives a lower die seat 4 to rotate to the loading area first, so that the copper-clad laminate is placed in the mold cavity of the lower die seat 4 for loading. The rotating disc 3 drives the lower die seat 4 with the copper-clad laminate to rotate to the cold pressing area;

[0075] At this time, the stamping oil cylinder 21 drives the upper die base 22 to move downward to close the mold with the lower die base 4 to perform cold pressing on the copper clad plate, and the stamping oil cylinder 21 drives the upper die base 22 to move upward to the top to reset, and then the cleaning mechanism cleans the debris attached to the lower end of the upper die base 22, and the cleaned debris falls downward into the material receiving box 223 for collection, thereby completing the cleaning of the debris at the lower end of the upper die base 22;

[0076] The rotating disc 3 drives the cold-pressed copper-clad plate and the lower die seat 4 to rotate to the flipping and unloading area, and pushes the transmission plate 63 through the extrusion plate 64 to separate the locking crown gear 6 from the rotating crown gear 44 in the locking mechanism, and at the same time, the transmission head 46 is engaged with the docking groove on the side of the docking head 45;

[0077] At this time, the output shaft of the second stepper motor in the flipping unloading area drives the transmission head 46 to rotate half of a circle, and the transmission head 46 drives the lower die base 4 to flip 180 degrees through the docking head 45 and the round shaft 41, so that the mold cavity opening of the lower die base 4 faces downward, and at the same time, the demoulding mechanism at the lower end of the lower die base 4 flips to the upper side;

[0078] The rotating disc 3 then drives the flipped lower die base 4 to rotate from the flipping and unloading area to the returning area. In this process, when the lower die base 4 and the demoulding mechanism rotate to the bottom of the fan-shaped limit plate 23, the fan-shaped limit plate 23 pushes the demoulding mechanism to move downward, and the cold-pressed copper-clad laminate in the mold cavity of the lower die base 4 is pushed downward by the lifting plate 5, thereby demoulding;

[0079] At the same time, the air blower mechanism blows the air downward along the air outlet 24, and the air blows obliquely downward along the vent 43 and the connecting inclined groove 42 to the zigzag cleaning groove. The air passes through the zigzag cleaning groove and blows downward along the inner wall of the mold cavity, thereby cleaning the debris on the inner wall of the mold cavity of the lower mold base 4.

[0080] The cleaning mechanism provided can effectively clean the debris on the upper die base 22, and the hair dryer structure and the cleaning brush 13 provided can cooperate to clean the debris on the lower die base 4 and the lifting plate 5. The cleaning process does not need to be performed manually, and will not affect the cold pressing operation of the new copper clad laminate in the cold pressing area, thereby reducing waiting time and improving work efficiency.

[0081] The cleaned lower die base 4 is rotated to the return zone by the rotating disc 3, and the output shaft of the second stepping motor in the return zone drives the transmission head 46 to rotate half of the circle, so that the lower die base 4 is turned 180 degrees and returned to the center, so that the mold cavity opening of the lower die base 4 faces upward;

[0082] Finally, the lower die base 4 after being straightened is rotated to the loading area by rotating the disc 3, so as to carry out loading, and the cycle is repeated, and the loading area, cold pressing area, flipping and unloading area and straightening area in the four areas can operate simultaneously without interfering with each other, that is, the loading area can load the copper-clad sheet into the inner cavity of a lower die base 4, the cold pressing area can cold-press the copper-clad sheet in a lower die base 4, the flipping and unloading area can unload the copper-clad sheet after cold pressing, and the straightening area can straighten the lower die base 4 after unloading and cleaning, and such reciprocating operation greatly improves the work efficiency.
