Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production, in particular to a double-station steel sheet feeding device for a flexible circuit board. Background Art

[0002] Flexible circuit boards are a type of circuit boards. The use of flexible circuit boards can make circuits more miniaturized and flexible. One of the advantages of flexible circuit boards is their flexibility. At the same time, this feature also limits the use of snaps to fix the product when it is streamlined on the carrier. During the production process, the product must be kept in a stable state. This requires the use of steel sheets for pressing after the product is placed to meet the needs of product fixation during production.

[0003] Currently, most of the methods of using steel sheets to press products are to use one workstation. After the product is adsorbed on the carrier, the steel sheet is quickly lowered to form a carrier-product-steel sheet structure, and then the structure is sent out. However, since the subsequent equipment production CT is short (referring to the short time required to complete a product or component from start to finish), a single workstation is used for loading, the loading time is long, and the number of structures sent out is small, which cannot meet the production of subsequent equipment and easily causes waste of production capacity of subsequent equipment.

[0004] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Utility Model Content

[0005] The utility model provides a double-station steel sheet feeding device for a flexible circuit board, aiming to solve the technical problem proposed in the above background technology that currently a single-station is used for feeding, the feeding time is long, the number of structures sent out is small, the production of subsequent equipment cannot be met, and the production capacity of subsequent equipment is easily wasted.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a double-station steel sheet feeding device for flexible circuit boards, the double-station steel sheet feeding device comprising a frame and a main streamline arranged in the frame; the main streamline is sequentially arranged with a front station, a middle station and a rear station along the flow direction of the carrier;

[0007] The front station and the rear station are both provided with a steel sheet loading mechanism, an adsorption mechanism, and a lifting mechanism; the middle station is provided with a lifting mechanism;

[0008] The upper steel sheet mechanism comprises a mounting column and a transfer structure, wherein the mounting column is fixedly connected to the frame; the transfer structure is slidably arranged relative to the side of the mounting column, and the transfer structure has a transfer end for positioning the steel sheet;

[0009] The adsorption mechanism is provided with an air suction head that rotates within a set angle so that the air suction head abuts against or separates from the surface of the carrier;

[0010] The lifting mechanism includes a lifting drive unit and a lifting head, and the lifting drive unit drives the lifting head to selectively lift the carrier located at the front station, the middle station and the rear station upward, so as to form an avoidance space for the carrier to pass through in the total streamline area where the front station, the middle station and the rear station are located;

[0011] The double-station steel sheet feeding device also includes a control circuit, which is electrically connected to the main flow line, the adsorption mechanism, the front station, the middle station and the lifting mechanism at the rear station.

[0012] In the above scheme, the relevant contents are explained as follows:

[0013] 1. The transfer end refers to the structure that fixes and positions the steel sheet, such as a suction cup or a manipulator;

[0014] 2. The setting angle is preferably 0-180 degrees, and the suction head abuts against or detaches from the carrier surface, so that the product (i.e., flexible circuit board) placed on the carrier surface can be vacuum adsorbed or only attached to the carrier surface;

[0015] 3. Selectively lifting upward means that, under the control of the control circuit, at least one of the carriers located at the front station, the middle station and the rear station is lifted;

[0016] 4. The control circuit needs to work in conjunction with the sensor so that the lifting drive units at the front station, middle station and rear station can coordinate and cooperate to achieve automation.

[0017] According to a further technical solution, the lifting mechanism comprises two side lifting structures, each of which is provided with at least one lifting head, and each of which is provided with a lifting drive unit, and the two side lifting structures are symmetrically arranged on both sides in the direction of the total streamline width so that the carrier can be lifted from both ends.

[0018] According to a further technical solution, the side lifting structure includes a guide plate, a lifting plate, an upper limit point and a lower limit point;

[0019] The guide plate is fixedly arranged on the side of the main streamline; the surface of the guide plate has a guide hole;

[0023] The upper limit point and the lower limit point are respectively set at the two ends of the sliding track of the lifting plate to limit the sliding of the lifting plate. With this design, when the carrier is lifted, it is lifted at both ends. If it is lifted from the middle of the carrier, there will be a lifting drive unit in the avoidance space, so that the avoidance space is blocked. When the carrier flows on the general streamline, the carrier cannot pass through the avoidance space.

[0024] In a further technical solution, a spacer block is installed between the guide plate and the side of the main streamline, so that there is a gap between the guide plate and the side of the main streamline. Since the carrier is raised at both ends, and the two guide plates are symmetrically arranged in the width direction of the main streamline and are arranged on opposite sides of the main streamline, the carrier may shake and deflect during the circulation of the carrier on the main streamline. This design can prevent the edge of the carrier from scratching the guide plate.

[0025] According to a further technical solution, the overall flow line includes a processing section flow line and a delivery section flow line;

[0026] The processing section streamline comprises two conveying bars arranged in a straight line, and the two conveying bars are fixedly mounted on the frame; the surfaces of the two conveying bars on opposite sides are connected to each guide plate correspondingly through a spacer block;

[0027] The delivery section streamline is arranged at the conveying end of the processing section streamline; the delivery section streamline includes two delivery bars, and the two delivery bars are respectively arranged corresponding to the two conveying bars to deliver the carrier from the processing section streamline. With this design, the delivery of the carrier and the conversion between each workstation are automated without manual loading.

[0028] According to a further technical solution, the adsorption mechanism includes a bearing seat and a swing arm cylinder, the bearing seat is connected to the frame, a lifting cylinder is connected to the bearing seat, a support arm is installed at the output end of the lifting cylinder, and one end of the support arm away from the lifting cylinder is connected to a rotating arm through a rotating shaft;

[0029] Taking the distance from the two ends of the rotating arm to the rotating axis as a reference, the two ends of the rotating arm are marked as the distal end and the proximal end respectively;

[0030] The swing arm cylinder is arranged on the side wall of the support arm, the proximal end of the rotating arm is hinged to the movable end of the swing arm cylinder and is driven to rotate by the swing arm cylinder, and the distal end of the rotating arm is installed with a vacuum suction cup;

[0031] The rotating arm and the vacuum suction cup are combined to form a suction head. With this design, the suction mechanism can avoid the circulating carrier in the process of generating the avoidance space when the carrier is circulating.

[0032] A further technical solution is that a lifting slide rail is provided on the mounting column along its length direction, the lifting slide rail is connected to the transfer structure, the lifting structure is provided inside the lifting slide rail, and the movable end portion of the lifting structure has a driving structure fixedly connected to the lifting slide rail, so that the transfer structure is driven by the driving structure to move up and down in a straight line.

[0033] According to a further technical solution, the transfer structure includes a fixed frame connected to the lifting structure and a mounting platform slidably arranged with the fixed frame, the fixed frame is provided with a first cylinder with a movable end connected with the mounting platform, and the mounting platform is slidably arranged relative to the width direction of the processing section streamline;

[0034] The mounting platform is provided with a second cylinder and a third cylinder, the movable ends of the second cylinder and the third cylinder are arranged opposite to each other, and the movable ends of the second cylinder and the third cylinder are both connected to a balance fixing plate, and the transfer end is arranged on a side surface of the balance fixing plate away from the mounting platform. With this design, the steel sheet to be covered can be fixed regardless of different orientations or sizes.

[0035] A further technical solution also includes a lifting and scanning code binding mechanism; the lifting and scanning code binding mechanism includes a lifting frame, a bearing frame and a code scanner arranged in a frame;

[0036] The lifting frame has a guide slot along its length, and the support frame is arranged in the guide slot and slides relative to the support frame;

[0037] The delivery section streamline is arranged on the support frame and is located at the conveying end of the processing section streamline, and the code scanner is arranged on the delivery section streamline.

[0038] According to a further technical solution, the barcode scanner includes two first barcode scanning components and a second barcode scanning component;

[0039] The two first code scanning components are disposed on one of the delivery bars and located at two ends of the delivery bar, so as to scan the code on one side of the upper surface of the carrier;

[0040] The second code scanning component is arranged on another feeding bar to scan the code on one side of the lower surface of the carrier.

[0047] The utility model can realize the double-station loading and steel sheet pressing of products through the jacking mechanism at the front station, the middle station and the rear station, saving working time and meeting the production rhythm of the rear equipment. At the same time, the double station can be automatically carried out on a streamline, with high efficiency and no manual auxiliary loading.

[0048] Secondly, when the steel sheet is pressed, vacuum adsorption is performed first to ensure that the product position is fixed before the steel sheet is pressed. In addition, the adsorption mechanism also needs to avoid the space when the avoidance space is generated to meet the requirements of the carrier transmission interaction between the double workstations.

[0049] In order to facilitate manual loading of products and reduce the height of the manual loading flow line, a lifting and scanning Link station is added in the rear section. After the carrier flows into the rear section, the lifting mechanism lifts the rear section flow line to the height of the subsequent machine flow line before flowing out.

[0067] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0068] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0069] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0070] See attached Figure 1-Figure 16 As shown, a double-station steel sheet feeding device for a flexible circuit board includes a frame 1 and a main streamline 2 arranged in the frame 1; the main streamline 2 is sequentially provided with a front station, a middle station and a rear station along the flow direction of the carrier 16; the front station and the rear station are both provided with a steel sheet loading mechanism 3, an adsorption mechanism 4 and a lifting mechanism 5; the middle station is provided with a lifting mechanism 5; the steel sheet loading mechanism 3 includes a mounting column 6 and a transfer structure 7, and the mounting column 6 is fixedly connected to the frame 1; the transfer structure 7 is slidably arranged relative to the side of the mounting column 6, and the transfer structure 7 has a transfer end for positioning the steel sheet; (generally, the transfer end can select a suction cup, and compared with a manipulator, it has higher stability when grasping and fixing such large and thin parts).

[0071] The suction mechanism 4 is provided with a suction head 8 that rotates within a set angle so that the suction head 8 abuts against or separates from the surface of the carrier 16 .

[0072] The lifting mechanism 5 includes a lifting drive unit 9 and a lifting head 10. The lifting drive unit 9 drives the lifting head 10 to selectively lift upward the carrier 16 located at the front station, the middle station and the rear station to form an avoidance space for the carrier 16 to pass through in the main streamline 2 area where the front station, the middle station and the rear station are located.

[0073] The double-station steel sheet feeding device also includes a control circuit, which is electrically connected to the main flow line 2, the adsorption mechanism 4, and the lifting mechanisms 5 at the front station, the middle station, and the rear station.

[0074] The utility model can realize the double-station loading and steel sheet pressing of products through the jacking mechanism 5 at the front station, the middle station and the rear station, saving working hours and meeting the production rhythm of the rear equipment. At the same time, the double-station can be automatically carried out on a streamline without manual auxiliary loading.

[0075] Secondly, when the steel sheet is pressed, vacuum adsorption is performed first to ensure that the product position is fixed before the steel sheet is pressed, and the adsorption mechanism 4 also needs to avoid the space when the avoidance space is generated to meet the need for giving way during the carrier transmission interaction between the double workstations.

[0076] Specifically, in order to solve the technical problem raised in the background technology that currently a single station is used for loading, the loading time is long, the number of structures sent out is small, and the production of subsequent equipment cannot be met, which easily causes waste of production capacity of subsequent equipment, during work, the carrier 16 with the product (the product refers to the flexible circuit board) can be directly placed at the input end of the main flow line 2 (generally refers to the area for sending to the front station), and then the carrier will enter the front station, the middle station and the rear station along the main flow line 2;

[0077] If you are just starting to launch:

[0078] The first carrier 16 may arrive at the rear station first, and the second carrier 16 arrives at the front station. If the third carrier 16 arrives at the front station, the control circuit will start the lifting mechanism 5 at the front station according to the sensor (the sensor will be set at the three stations to meet the purpose of forming an avoidance space for the carrier 16 to pass through in the area of ​​the total streamline 2 where the front station, the middle station and the rear station are located. The control circuit only needs to meet the purpose of being able to control the total streamline 2, the adsorption mechanism 4, the front station, the middle station and the rear station. The lifting mechanism 5, that is, when the sensor detects that there is a carrier 16 at the front station, the lifting drive unit 9 at the front station drives the lifting head 10 to lift the carrier 16 at the front station upward to form an avoidance space for the carrier 16 to pass through in the area of ​​the total streamline 2 where the front station is located. After that, the carrier 16 will move to the middle station through the avoidance space for temporary caching;

[0079] After the carrier 16 reaches the corresponding station, the suction head 8 on the suction mechanism 4 rotates to a set angle to abut against the surface of the carrier 16, thereby performing a vacuum suction action (it should be noted that in order to enable the product to complete the vacuum suction action, an air flow hole can be provided on the surface of the carrier 16. When the product is pressed on the surface of the carrier 16, one end of the air flow hole is blocked, and the suction head 8 is connected to the other end to achieve vacuum suction.)

[0080] Afterwards, the steel sheet is placed on the carrier 16 by the upper steel sheet mechanism 3 to form a carrier 16 - product - steel sheet structure.

[0081] After the first and second carriers 16 complete the steel sheet pressing, an avoidance space is created in the middle station (it should be noted that after the suction head 8 participates in completing the vacuum adsorption action of the product on the carrier 16, once the carrier 16 needs to be avoided, the suction head 8 also needs to stop vacuum adsorption and rotate the set angle to return to the initial position to complete the avoidance action to avoid the subsequent carrier 16 circulation being affected), so that the carrier 16-product-steel sheet structure at the front station can be sent away, and then the third carrier 16 at the middle station moves to the rear station, the fourth carrier 16 moves to the front station and performs the steel sheet pressing action, and when the fifth carrier 16 is circulating, once there is a carrier 16 at the front station, the fifth carrier 16 needs to be transferred to the middle station, if not, the fifth carrier 16 enters the front station (it should be noted that the circulation speed of the carrier 16 should be faster, otherwise the carrier 16 will always be performing the steel sheet pressing action at the front station).

[0082] Alternatively, the first carrier 16 arrives at the front station first, and then the second carrier 16 passes through the front station to exit the avoidance space and arrives at the rear station, and the third arrives at the middle station. However, this method has certain requirements on the flow speed of the carrier 16, because it is necessary to control the carriers 16 on each station to be matched at the corresponding station, and the situation in which the carrier 16 exceeds a certain station cannot occur. Therefore, most people choose the first work flow.

[0083] In order to ensure the stability of the carrier 16 when it is lifted, in some specific embodiments, the lifting mechanism 5 includes two side lifting structures, each of which is provided with at least one lifting head 10, and each of which is provided with a lifting drive unit 9. The two side lifting structures are symmetrically arranged on both sides in the direction of the total streamline width so that the carrier 16 can be lifted from both ends.

[0084] In some specific embodiments, the side lifting structure includes a guide plate 11, a lifting plate 12, an upper limit point 14 and a lower limit point 15;

[0085] The guide plate 11 is fixedly arranged on the side of the main flow line 2; the surface of the guide plate 11 has a guide hole 13;

[0086] The lifting plate 12 is located on the side of the guide plate 11 away from the main streamline 2 and is slidably connected in the guide hole 13 and connected to the movable end of the lifting drive unit 9 fixed on the side wall of the guide plate 11 (the sliding of the lifting plate 12 is achieved by the movable end of the lifting drive unit 9);

[0087] The lifting head 10 is located on the side of the guide plate 11 close to the main flow line 2 and is connected to the lifting plate 12; (the fixed position of the lifting head 10 can be specifically referred to Figure 7 ).

[0088] The upper limit point 14 and the lower limit point 15 are fixedly mounted on the surface of the guide plate 11 and are located on the same side as the lifting plate 12;

[0089] The upper limit point 14 and the lower limit point 15 are respectively arranged at two ends of the sliding track of the lifting plate 12 so that the sliding of the lifting plate 12 is restricted.

[0090] In some specific embodiments, a spacer block 19 is installed between the guide plate 11 and the side of the main streamline 2 so that there is a gap between the guide plate 11 and the side of the main streamline 2 .

[0091] In some specific embodiments, the overall flow line 2 includes a processing section flow line 17 and a delivery section flow line 39;

[0092] The processing section streamline 17 includes two conveying bars 18 arranged in a straight line, and the two conveying bars 18 are fixedly mounted on the frame 1; the surfaces of the two conveying bars 18 on opposite sides are connected to each guide plate 11 through a spacer block 19;

[0093] The delivery section flow line 39 is arranged at the conveying end of the processing section flow line 17 ; the delivery section flow line 39 includes two delivery bars 40 , which are respectively arranged corresponding to the two conveying bars 18 for delivering the carrier 16 from the processing section flow line 17 .

[0094] To create an escape space:

[0095] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 7 , and use the front workstation as an example, because the work process of the back workstation is the same as that of the front workstation.

[0096] Under normal circumstances, the gap exists to ensure that the edge of the carrier body 16 is within the gap and above the lifting head 10 , so as to facilitate the lifting of the lifting head 10 .

[0097] When the carrier 16 moves to the front workstation, if an avoidance space needs to be formed, the two lifting plates 12 are directly pushed upward along the corresponding guide holes 13 through a driving device, such as an electric push rod or a cylinder. During the sliding process of the two lifting plates 12, the corresponding lifting heads 10 are pushed up until they abut against the lower surfaces of the two ends of the carrier 16 (at this time, the carrier 16 abuts against the surface of the processing section streamline 17), and then the two lifting plates 12 continue to rise with the lifting heads 10 until each lifting plate 12 abuts against the corresponding upper limit position 14, thereby forming an avoidance space.

[0098] When the carrier 16 needs to be circulated, the two lifting plates 12 lift the carrier 16 downward until each lifting plate 12 abuts against the corresponding lower limit point 15, and the carrier 16 also falls on the surface of the processing section streamline 17.

[0099] It should be noted that the processing section streamline 17 does not move all the time, and will only work when the carrier 16 needs to flow.

[0100] In some specific embodiments, the adsorption mechanism 4 includes a bearing seat 20 and a swing arm cylinder 21, the bearing seat 20 is connected to the frame 1, a lifting cylinder 22 is connected to the bearing seat 20, a support arm 23 is installed at the output end of the lifting cylinder 22, and one end of the support arm 23 away from the lifting cylinder 22 is connected to a rotating arm 24 through a rotating shaft;

[0101] Taking the distance from the two ends of the rotating arm 24 to the rotating axis as a reference, the two ends of the rotating arm 24 are marked as the distal end and the proximal end respectively;

[0102] The swing arm cylinder 21 is arranged on the side wall of the support arm 23, the proximal end of the rotating arm 24 is hinged to the movable end of the swing arm cylinder 21 and is driven to rotate by the swing arm cylinder 21, and the distal end of the rotating arm 24 is equipped with a vacuum suction cup 25;

[0103] The rotating arm 24 and the vacuum suction cup 25 are combined to form the suction head 8.

[0104] To achieve vacuum adsorption:

[0105] Reference Figure 9-11 .

[0106] Under normal circumstances, the swing arm cylinder 21 will not work. At this time, the rotating arm 24 is often parallel to the support arm 23. At the same time, the lifting cylinder 22 is also in a retracted state, that is, the movable end of the lifting cylinder 22 is not raised, and the support arm 23 and the conveying bar 18 are vertically arranged.

[0107] Once adsorption is required, the carrier 16 on the upper surface of the conveying bar 18 will be lifted up by the two lifting plates 12, and then the movable end of the swing arm cylinder 21 will work, thereby pushing the rotating arm 24 to rotate with the rotating shaft as the rotation center until the rotating arm 24 is perpendicular to the supporting arm 23. At this time, the rotating arm 24 moves with the vacuum suction cup 25 to the bottom of the carrier 16, and then the movable end of the lifting cylinder 22 rises to lift the supporting arm 23 and the rotating arm 24 to achieve the avoidance of the adsorption mechanism 4, specifically, mainly refers to the avoidance of the suction head 8.

[0108] When the suction head 8 is evacuated, the vacuum suction cup 25 will contact the surface directly below the carrier 16 to perform a vacuum suction operation.

[0109] In some specific embodiments, a lifting rail 26 is provided on the mounting column 6 along its length direction, and the lifting rail 26 is connected to the transfer structure 7. A lifting structure is provided inside the lifting rail 26, and a movable end of the lifting structure has a driving structure 27 fixedly connected to the lifting rail 26 (the driving structure 27 can be a motor, and the lifting structure can be a screw rod), so that the transfer structure 7 is driven by the driving structure 27 to move up and down in a straight line.

[0110] In some specific embodiments, the transfer structure 7 includes a fixed frame 28 connected to the lifting structure and a mounting platform 29 slidably arranged with the fixed frame 28, a first cylinder 30 having a movable end connected to the mounting platform 29 is provided on the fixed frame 28, and the mounting platform 29 is slidably arranged relative to the width direction of the processing section streamline 17;

[0111] A second cylinder 31 and a third cylinder 32 are provided on the mounting platform 29. The movable ends of the second cylinder 31 and the third cylinder 32 are arranged opposite to each other, and the movable ends of the second cylinder 31 and the third cylinder 32 are both connected to a balancing fixed plate 33. The transfer end is arranged on a side surface of the balancing fixed plate 33 away from the mounting platform 29.

[0112] In order to complete the pressing of steel sheets: (such as Figure 12-14 ).

[0113] After the carrier 16 is lifted, a vacuum adsorption action is required (generally, the adsorption action can also be performed when the carrier 16 is on the surface of the conveyor bar 18, that is, a through hole connected to the upper surface of the carrier 16 is opened on the side of the carrier 16, and the vacuum suction cup 25 is arranged on the side of the rotating arm 24. Once the rotating arm 24 rotates, the vacuum suction cup 25 can be pushed to connect with the through hole on the side of the carrier 16, thereby completing the adsorption action. However, when operating in this way, the lifting cylinder 22 and the driving device of the lifting plate 12 are required to work together, and height difference is likely to occur during the working process, resulting in the adsorption being affected. Therefore, the probability of selecting this method is relatively low).

[0114] After the adsorption action is completed, the driving structure 27 works, thereby driving the lifting slide rail 26 to guide the transfer structure 7 to lower the adsorbed steel sheet to the carrier 16 (the process of the transfer structure 7 adsorbing the steel sheet is: first, the first cylinder 30 pushes the mounting table 29 to slide on the fixed frame 28 along the width direction of the processing section streamline 17 until the transfer end, that is, the vacuum suction cup, is directly above the steel sheet, and then the second cylinder 31 and the third cylinder 32 are driven at the same time to adjust the distance between the two balancing fixing plates 33 to both sides of the steel sheet to prevent the balancing fixing plates 33 from being too close and causing uneven force, and then, the lifting slide rail 26 is used to guide the transfer end to move to the steel sheet to complete the adsorption).

[0115] In some specific embodiments, a lifting and scanning code binding mechanism 34 is also included; the lifting and scanning code binding mechanism 34 includes a lifting frame 35, a bearing frame 36 and a code scanner 37 arranged in the frame 1;

[0116] The lifting frame 35 has a guide slot 38 on its side along its length direction, and the carrier frame 36 is disposed in the guide slot 38 and is slidably disposed relative to the carrier frame 36;

[0117] The delivery section flow line 39 is disposed on the carrier 36 and is located at the conveying end of the processing section flow line 17 , and the code scanner 37 is disposed on the delivery section flow line 39 .

[0118] In some specific embodiments, the barcode scanner 37 includes two first barcode scanning components 41 and a second barcode scanning component 42;

[0119] Two first code scanning components 41 are disposed on one of the delivery bars 40 and located at two ends of the delivery bar 40 to scan the code on one side of the upper surface of the carrier 16;

[0120] The second code scanning component 42 is disposed on the other feeding bar 40 to scan the code on one side of the lower surface of the carrier 16 .

[0121] In order to further improve production efficiency, it is necessary to enable the formed carrier 16-product-steel sheet structure to be quickly connected to subsequent equipment, so: (such as Figure 15-16 ).

[0122] When the carrier 16-product-steel sheet structure is transferred to the two delivery bars 40 (the movement of the carrier 36 and the lifting frame 35 can refer to the screw sleeve structure. Under normal circumstances, the carrier 36 is at the bottom of the lifting frame 35, and the surfaces of the two delivery bars 40 are flush with the surfaces of the two conveying bars 18. After the carrier 16-product-steel sheet structure flows out of the two conveying bars 18, it will move directly to the surfaces of the two delivery bars 40).

[0123] The two first scanning components 41 will scan the product from the left and right sides, and the second scanning component 42 will scan the product from the bottom to detect and obtain information about the product, the steel sheet, and the carrier 16.

[0124] After the code scanning is completed, the carrier 36 is lifted until the surfaces of the two delivery bars 40 are flush with the flow lines on the rear processing equipment, so that the carrier 16 can be delivered.

[0125] That is, in order to facilitate manual loading of products and reduce the height of the manual loading streamline, a lifting and scanning Link station is added in the rear section (the lifting and scanning binding mechanism 34 is set at the lifting and scanning Link station, that is, the area where the lifting and scanning binding mechanism 34 is located is the setting area of ​​the lifting and scanning Link station). After the carrier 16 flows into the lifting and scanning Link station, the lifting frame 35 and the supporting frame 36 cooperate to lift the carrier 16 transferred to the lifting and scanning Link station to the same height as the subsequent machine streamline and then flow out.

[0126] Working principle: During operation, the carrier 16 with the product (the product refers to the flexible circuit board) can be directly placed at the input end of the main flow line 2 (generally refers to the area for sending to the front station), and then the carrier will enter the front station, the middle station and the back station along the main flow line 2;

[0127] At this time, the first carrier 16 arrives at the rear station first, and the second carrier 16 arrives at the front station. If the third carrier 16 is to arrive at the front station, the control circuit will start the lifting mechanism 5 at the front station according to the sensor (the sensor will be set at the three stations to meet the purpose of forming an escape space for the carrier 16 to pass through in the area of ​​the total streamline 2 where the front station, the middle station and the rear station are located), that is, when the sensor detects that there is a carrier 16 at the front station, the lifting drive unit 9 at the front station drives the lifting head 10 to lift the carrier 16 at the front station upward to form an escape space for the carrier 16 to pass through in the area of ​​the total streamline 2 where the front station is located, and then the carrier 16 will move to the middle station through the escape space for temporary caching;

[0128] After the carrier 16 reaches the corresponding workstation, the suction head 8 on the adsorption mechanism 4 rotates to a set angle to abut the surface of the carrier 16, thereby performing a vacuum adsorption action (it should be noted that in order to enable the product to complete the vacuum adsorption action, air flow holes can be provided on the surface of the carrier 16. When the product is pressed against the surface of the carrier 16, one end of the air flow hole is blocked, and the suction head 8 is connected to the other end to achieve vacuum adsorption).

[0129] Afterwards, the steel sheet is placed on the carrier 16 by the upper steel sheet mechanism 3 to form a carrier 16 - product - steel sheet structure.

[0130] After the first and second carriers 16 complete the steel sheet pressing, an avoidance space is created in the middle station (it should be noted that after the suction head 8 participates in completing the vacuum adsorption action of the product on the carrier 16, once the carrier 16 needs to be avoided, the suction head 8 also needs to stop vacuum adsorption and rotate the set angle to return to the initial position to complete the avoidance action to avoid the subsequent carrier 16 circulation being affected), so that the carrier 16-product-steel sheet structure at the front station can be sent away, and then the third carrier 16 at the middle station moves to the rear station, the fourth carrier 16 moves to the front station and performs the steel sheet pressing action, and when the fifth carrier 16 is circulating, once there is a carrier 16 at the front station, the fifth carrier 16 needs to be transferred to the middle station, if not, the fifth carrier 16 enters the front station (it should be noted that the circulation speed of the carrier 16 should be faster, otherwise the carrier 16 will always be performing the steel sheet pressing action at the front station).

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
