Description

Technical Field

[0001] This invention relates to the field of equipment, and more specifically to a rotary conveying device. Background Technology

[0002] Automotive radar systems include metal sheets, which are one of the components. The metal sheet is a thin sheet structure, fixed by a strip material structure, meaning a strip contains several equally spaced metal sheets. In automated manufacturing, a punching die is used to separate the metal sheets from the strip, forming individual sheets. These sheets are then manually placed into a semi-finished product for fixing.

[0003] There are two traditional methods for ejecting stamped products from the die: one is to directly eject the stamped and cut product from the die, and the other is for the stamped and cut product to fall directly from the blanking port. Both methods have the following problems: the product may have scratches on its surface after ejection, and the product is scattered and cannot be effectively collected, which is detrimental to the assembly or processing of the next step. Furthermore, because the metal sheet is thin, it is prone to bending during the stacking process, affecting subsequent processing and the performance of the product itself. Summary of the Invention

[0004] Therefore, the technical problem to be solved by this invention is how to improve processing efficiency while ensuring the quality of the metal sheet. A rotary conveying device includes:

[0005] A first driving mechanism, the first driving mechanism includes a first driving source and a first driving rod, the first driving rod is connected to a linkage plate, and the first driving source drives the first driving rod to move along a first direction;

The mounting plate extends between the base plate and the float plate, and a steel ball is provided between the mounting plate and the base plate. The mounting plate has a first through hole, and the float plate has a second through hole. The first equalizing screw passes through the first through hole and connects to the base plate. A first gap is provided between the outer wall of the first equalizing screw and the inner wall of the first through hole. The second equalizing screw passes through the second through hole and abuts against the mounting plate. A second gap is provided between the outer wall of the second equalizing screw and the inner wall of the second through hole.

[0012] The floating suction assembly includes a limiting pin, the mounting plate has a third through hole, one end of the limiting pin is connected to the base plate, the other end of the limiting pin extends to the third through hole, and a third gap is provided between the outer sidewall of the limiting pin and the inner sidewall of the third through hole, the third gap being smaller than the first gap and the second gap.

[0013] The base plate is fixed with a first fixing member, the steel ball is fixed to the first fixing member, and the mounting plate is fixed with a second fixing member, the second fixing member abutting against the steel ball.

[0019] It also includes a fixing plate, the base is connected and fixed to the fixing plate, the support plate is located above the fixing plate, and the linkage plate is located below the fixing plate.

[0020] The technical solution of this invention has the following advantages:

[0021] 1. The rotary conveying device provided by this invention, with this structural design, can directly transport the cut products from inside the stamping die and then directly assemble them at the next workstation. This mechanism achieves point-to-point efficiency, with the mechanical structure directly picking up materials, eliminating the need for manual collection of cut products, greatly improving production efficiency. The suction head not only picks up the products but also works in conjunction with the stamping process. By abutting against the products, the suction head positions and fixes them, better realizing stamping and improving stamping efficiency. Furthermore, the floating suction component forms a floating structure, which eliminates errors and prevents the suction head from failing to enter the stamping cavity during movement, improving processing accuracy. If the mechanisms are rigidly coupled, wear can easily occur between them when errors occur, leading to damage to the entire equipment. The floating structure avoids this wear phenomenon, improves accuracy, and indirectly increases service life.

[0022] 2. The rotary conveying device provided by this invention creates a floating effect through the combination of a base plate, a floating plate, and a mounting plate. Specifically, the floating effect refers to the fact that the mounting plate and the floating plate can float within a certain range. When the first drive mechanism or the rotary mechanism is activated, the mounting plate can drive the entire floating suction assembly to move. Due to the setting of the first gap and the second gap, a movement space is formed, thereby achieving the effect of adjusting the position. After the guide post cooperates with the stamping die, the suction head is guided by the guide post, ultimately allowing the suction head to enter the stamping cavity without scraping against the inner wall of the stamping cavity. Alternatively, an elastic structure can also be used to create the floating effect; however, the disadvantage of an elastic structure is that it cannot precisely control the accuracy.

[0023] 3. The rotary conveying device provided by the present invention has a limiting pin, which further restricts the floating range so that the floating range is kept within a preset value, which is 10-100 mils.

[0024] 4. The present invention provides a rotary conveying device in which steel balls are slidably connected between the base plate and the mounting plate. The inclusion of a first fixing member and a second fixing member improves the strength of the connection and prevents friction of the steel balls from affecting the strength of the base plate and the mounting plate. When the mounting plate moves downwards, the mounting plate drives the base plate to move downwards via the steel balls, achieving a linkage effect.

[0025] 5. The present invention provides a rotary conveying device in which an elastic element provides an elastic buffering effect between the mounting plate and the floating plate.

[0026] 6. The present invention provides a rotary conveying device in which an elastic positioning pin is used to cooperate with a metal sheet to achieve a positioning effect. The riveting groove is used when the metal sheet and the semi-finished product are engaged. The side of the semi-finished product that is engaged with the metal sheet has a protrusion. When the ejector rod drives the entire floating suction assembly toward the semi-finished product, the protrusion and the riveting groove cooperate to form a riveting of the metal sheet, thereby achieving a connection and fixation between the metal sheet and the semi-finished product. When the suction head is removed, the suction head will not drive the metal sheet to move.

[0027] 7. The rotary conveying device provided by the present invention has a guide rib that serves as a guide and prevents large-scale shaking.

[0028] 8. The rotary conveying device provided by the present invention uses a servo motor and a reducer to achieve a better driving effect. Compared with the instability of cylinder transmission, servo motor transmission is more stable. Moreover, the servo motor is installed in reverse, which can save installation space and reduce the overall height. The reducer has a deceleration effect, which can more accurately control the rotation angle.

[0029] 9. The present invention provides a rotary conveying device in which a support plate, a base, and a linkage plate work together to achieve the motion effect of the linkage plate. The first drive mechanism drives the linkage plate to move, and the support plate plays a supporting and limiting role, thereby improving the overall drive stability.

[0030] 10. The present invention provides a rotating conveying device in which the fixing plate provides an overall fixing effect. Attached Figure Description

[0047] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Example 1

[0049] This embodiment provides a rotary conveying device, as shown in the attached figure. Figures 1-10 As shown, it includes:

[0050] The first drive mechanism 11 includes a first drive source 111 and a first drive rod 112. The first drive rod 112 is connected to the linkage plate 12. When the first drive rod 112 moves, the linkage plate 12 also moves accordingly. The first drive source 111 drives the first drive rod 112 to move along a first direction. That is, when the first drive source 111 is activated, it drives the first drive rod 112 to move, and the first drive rod 112 drives the linkage plate 12 to move.

[0051] A rotating mechanism 13 is fixed to the linkage plate 12. Specifically, "fixed" means that when the linkage plate 12 moves, the rotating mechanism 13 also moves accordingly. The rotating mechanism 13 is connected to the mounting plate 14 and drives the mounting plate 14 to rotate. In this embodiment, the rotating mechanism 13 drives the mounting plate 14 to rotate relative to a first plane. The first plane is perpendicular to a first direction. In this embodiment, the first plane specifically refers to the plane formed by the X and Y axes (equivalent to a horizontal plane), and the first direction is the direction of the Z-axis. That is, the first drive rod 112 and the linkage plate 12 both move along the Z-axis direction. The mounting plate 14 is parallel to the horizontal plane and rotates relative to it, meaning the mounting plate 14 rotates in the horizontal direction. A floating suction assembly 15 is connected to the mounting plate 14. The floating suction assembly 15 includes a suction head 151 and a guide post 152. The suction head 151 includes a suction nozzle 153, which is located on the bottom surface of the suction head 151. Specifically, the suction nozzle 153 refers to a vacuum suction nozzle 153, which works in conjunction with an external vacuum system to achieve the effect of adsorption and fixation. The suction nozzle 153 is one component of the suction head 151; the suction nozzle 153 picking up the metal sheet 20 is equivalent to the suction head 151 picking up the metal sheet 20. The floating suction component 15 floats relative to the mounting plate 14. This relative floating can mean that the floating suction component 15 is fixed and the mounting plate 14 is floating; or it can mean that the floating suction component 15 is floating and the mounting plate 14 is fixed. Here, the floating can be horizontal (backward, left, right) or vertical (up, down) in the Z-axis direction, which can be adjusted according to actual needs by those skilled in the art. In this embodiment, the floating configuration is primarily to eliminate errors, specifically the errors between the suction head 151 and the stamping cavity 161 and the bearing 17. Due to precision control issues, during equipment processing and assembly, it is impossible to guarantee that the central axis of the suction head 151 is coaxial with the central axis of the stamping cavity 161 and the central axis of the bearing 17. Furthermore, deviations can occur during movement. The floating configuration eliminates these deviations, better achieving the fit between the suction head 151 and the stamping cavity 161, and between the suction head 151 and the bearing 17. It should also be noted that, under the action of the first drive mechanism 11 and the rotating mechanism 13, and through the transmission cooperation of the linkage plate 12 and the mounting plate 14, the floating suction assembly 15 can move up and down along the Z-axis and can also rotate relative to the horizontal plane.

[0052] The pressing mechanism 18 includes a second drive source 181 and a pressing rod 182. The second drive source 181 drives the pressing rod 182 to move. Here, the pressing rod 182 moves along the first direction, that is, the pressing rod 182 moves along the Z-axis direction. The movement trajectory of the floating suction component 15 intersects with the movement trajectory of the pressing rod 182. When the floating suction component 15 rotates to a position directly below the pressing rod 182, the lower end of the pressing rod 182 will abut against the floating suction component 15 when the pressing rod 182 moves vertically downward.

[0053] The unloading mechanism 19 includes a third drive source 191 and an unloading rod 192. The third drive source 191 drives the unloading rod 192 to move. Here, the movement direction of the unloading rod 192 is the same as that of the pressure rod 182. The unloading rod 192 also moves along the first direction, that is, the unloading rod 192 moves along the Z-axis. The movement trajectory of the floating suction component 15 intersects with the movement trajectory of the unloading rod 192. When the floating suction component 15 rotates to a position directly below the unloading rod 192, the lower end of the unloading rod 192 will abut against the floating suction component 15 when the unloading rod 192 moves vertically downward.

[0054] In the first state, the guide post 152 engages with the stamping die 16. Specifically, the stamping die 16 has a hole for the guide post 152, allowing it to pass through and provide guidance and positioning. Then, through the floating adjustment of the floating suction assembly 15, the suction head 151 can move more effectively into the stamping cavity 161 of the stamping die 16. In other words, the guide post 152 engages with the stamping die 16 first, and then the suction head 151 abuts against the metal sheet 20. The metal sheet 20 is a strip structure that enters the stamping cavity 161, meaning one metal sheet 20 is positioned within the cavity before the suction head 151 abuts against it. After the metal sheet 20 is stamped, the strip 201 moves, and adjacent metal sheets 20 enter the stamping cavity 161, creating a continuous stamping effect. In this embodiment, the direction in which the suction head 151 moves to the stamping chamber 161 is opposite to the stamping direction of the stamping head. For example, when the suction head 151 moves downward along the Z-axis, the stamping head of the stamping die 16 moves upward along the Z-axis; conversely, when the suction head 151 moves upward along the Z-axis, the stamping head of the stamping die 16 moves downward along the Z-axis. In this embodiment, taking the stamping head stamping upward along the Z-axis as an example, that is, stamping from bottom to top, this stamping method, in conjunction with the rotary conveying device in this embodiment, can optimize the space occupied by the entire machine and make the layout more reasonable. In this embodiment, the guide column 152 moves downward along the Z-axis, specifically through the operation of the first drive mechanism 11. The first drive rod 112 moves, driving the entire linkage plate 12 downward along the Z-axis. The rotating mechanism 13 and the mounting plate 14 move in tandem with the linkage plate 12. When the linkage plate 12 moves, the rotating mechanism 13 and the mounting plate 14 also move downward. The mounting plate 14 then drives the floating suction assembly 15 downward along the Z-axis. At this time, the guide column 152 also creates a movement effect, thus achieving the effect of the first drive mechanism 11 driving the guide column 152 and the suction head 151 to move. The pressure rod 182 abuts against the floating suction assembly 15 and applies pressure to the floating suction assembly 15, creating a pressing effect to prevent the punch head from affecting the floating suction assembly 15 above during the impact process. Since the stamping die 16 and the punch head are existing technologies, the specific structure of the stamping die 16 is not shown in detail in the accompanying drawings. Meanwhile, the material strip 201 is fed horizontally. The material strip 201 can be rotated by the material tray or pulled by a cylinder or hydraulic cylinder to form a stamping and cutting process for individual metal sheets 20. This is existing technology and therefore not shown in the attached diagram. After stamping and cutting, the suction head 151 picks up the metal sheets 20. At this time, the suction nozzle 153 is working to achieve a suction effect. After stamping and cutting is completed, the stamping head is retracted and the material strip 201 moves to prepare for the next stamping.After the suction head 151 picks up the metal sheet 20, the second drive source 181 drives the pressure rod 182 to move upward along the Z-axis, canceling the pressure on the floating suction component 15. Then the first drive mechanism 11 works, and the first drive rod 112 drives the entire linkage plate 12 to move upward along the Z-axis, so that the suction head 151 is removed from the stamping cavity 161. After the suction head 151 is separated from the stamping cavity 161, the rotating mechanism 13 drives the mounting plate 14 to rotate, so that the suction head 151 moves to the top of the bearing 17 on which the semi-finished product is mounted. It is equivalent to the stamping die 16 being the first station and the bearing 17 being the second station. The first station is for cutting and picking up the metal sheet 20, and the second station is for placing the metal sheet 20 and riveting the metal sheet 20 with the semi-finished product.

[0055] In the second state, the guide post 152 engages with the bearing 17. This engagement is also a connection between the guide post 152 and the hole. The bearing 17 has a hole that engages with the guide post 152, through which the guide post 152 passes to provide a guiding effect. Here, the guide post 152 and the suction head 151 move downwards along the Z-axis via the first drive mechanism 11. The suction head 151, carrying the metal sheet 20, moves to the semi-finished product, causing the metal sheet 20 to adhere to it. At this point, the suction nozzle 153 is not working, meaning there is no adsorption between the metal sheet 20 and the suction head 151. However, some electrostatic adsorption still exists between them. If the suction head 151 moves upwards along the Z-axis directly, it will cause the metal sheet 20 to shift, affecting subsequent operations. The third drive source 191 drives the stripper rod 192 to move downward along the Z-axis. The stripper rod 192 abuts against the floating suction component 15 and applies pressure to the floating suction component 15, so that the metal sheet 20 is riveted and fixed to the semi-finished product. It should be noted that during the stamping and cutting process, the stamping head will not cause deformation of the metal sheet 20. However, at this station, after the metal sheet 20 is attached to the semi-finished product, the stripper rod 192 applies a downward force, causing deformation between the semi-finished product and the metal sheet 20, and the two are riveted and fixed. The riveting method here can be the fit between the protrusion and the groove, or other riveting methods. With this structural design, the cut products can be directly transported from inside the stamping die 16 and then directly assembled at the next workstation. This mechanism achieves point-to-point efficiency, with the mechanical structure directly picking up materials, eliminating the need for manual collection of cut products and greatly improving production efficiency. The suction head 151 not only picks up products but also works in conjunction with the stamping process. By abutting against the product, the suction head 151 positions and fixes the product, better realizing stamping and improving stamping efficiency. Furthermore, the floating suction component 15 forms a floating structure, which eliminates errors and prevents the suction head 151 from failing to enter the stamping cavity 161 during movement, improving processing accuracy. If the mechanisms are rigidly coupled, wear can easily occur between them when errors happen, leading to damage to the entire equipment. The floating structure avoids this wear phenomenon, improves accuracy, and indirectly increases service life.

[0056] Specifically, as shown in the attached document Figures 2-10As shown, the floating suction assembly 15 includes a base plate 154, a float plate 155, a first equalization screw 156, and a second equalization screw 157. The base plate 154 and the float plate 155 are connected by a first guide shaft 158. The float plate 155 is located above the base plate 154. The number of first guide shafts 158 can be adjusted according to actual needs. In this embodiment, four first guide shafts 158 are used as an example, that is, four first guide shafts 158 connect the base plate 154 and the float plate 155. Here, the first guide shafts 158 are precision guide shafts. The float plate 155 moves relative to the base plate 154. Here, the float plate 155 is movable, while the base plate 154 is fixed. The float plate 155 can move towards the base plate 154 along the Z-axis direction, but when the base plate 154 moves, the float plate 155 will move with the base plate 154. The suction head 151 is fixed to the float plate 155. One end of the suction head 151 is connected and fixed to the float plate 155, which can be fixed with bolts. The other end of the suction head 151 extends downward through the mounting plate 14 and the base plate 154. It should be noted that the suction head 151 only passes through the mounting plate 14 and the base plate 154; there is no connecting or fixing structure between the suction head 151 and the mounting plate 14 and the base plate 154. One end of the guide post 152 is connected to the float plate 155, and the other end of the guide post 152 extends downward through the mounting plate 14 and the base plate 154. The mounting plate 14 extends between the base plate 154 and the float plate 155. A steel ball 159 is provided between the mounting plate 14 and the base plate 154, connecting the mounting plate 14 and the base plate 154, thus creating a sliding connection between them, meaning that the mounting plate 14 can slide relative to the base plate 154. Mounting plate 14 has a first through hole 141, and floating plate 155 has a second through hole 1551. First leveling screw 156 passes through the first through hole 141 and is connected to base plate 154. A first gap 142 is provided between the outer wall of the first leveling screw 156 and the inner wall of the first through hole 141. The first leveling screw 156 defines the height of each position between mounting plate 14 and base plate 154, forming a parallel effect between mounting plate 14 and base plate 154. At this time, the first leveling screw 156 is fixedly connected to base plate 154. At this time, mounting plate 14 is floating. Mounting plate 14 can form a floating effect through the first gap 142. Mounting plate 14 can float in the horizontal direction. That is to say, the top surface of mounting plate 14 is limited in height by the first leveling screw 156, and the bottom surface of mounting plate 14 is limited by steel ball 159. At this time, mounting plate 14 can only float in the horizontal direction.The second equal-height screw 157 passes through the second through hole 1551 and abuts against the mounting plate 14. A second gap 1552 is provided between the outer wall of the second equal-height screw 157 and the inner wall of the second through hole 1551. The second equal-height screw 157 further restricts the positional relationship of the mounting plate 14. Here, the second equal-height screw 157 restricts the highest position of the floating plate 155 in the Z-axis direction. The floating plate 155 can move relative to the mounting plate 14 and the base plate 154, that is, the floating plate 155 can float in the Z-axis direction. Moreover, the setting of the second gap 1552 allows the floating plate 155 to float in the horizontal direction as well. When the floating plate 155 can float, the suction head 151 connected to the floating plate 155 can also float. The combination of the base plate 154, the float plate 155, and the mounting plate 14 creates a floating effect. Specifically, this floating effect means that within a certain range, both the mounting plate 14 and the float plate 155 can float. When the first drive mechanism 11 or the rotating mechanism 13 is activated, the mounting plate 14 can drive the entire floating suction assembly 15 to move. Due to the setting of the first gap 142 and the second gap 1552, a movement space is formed, thus achieving a position adjustment effect. After the guide post 152 cooperates with the stamping die 16, the suction head 151 is guided by the guide post 152, ultimately allowing the suction head 151 to enter the stamping cavity 161 without scraping against the inner wall of the stamping cavity 161. Alternatively, an elastic structure can also be used to create a floating effect, but the disadvantage of an elastic structure is that it cannot precisely control accuracy.

[0057] Specifically, as shown in the attached document Figures 5-10 As shown, the floating suction assembly 15 includes a limiting pin 150. The mounting plate 14 has a third through hole 143. One end of the limiting pin 150 is connected to the base plate 154, and the other end of the limiting pin 150 extends to the third through hole 143. A third gap 1501 is provided between the outer wall of the limiting pin 150 and the inner wall of the third through hole 143. The third gap 1501 is smaller than the first gap 142 and the second gap 1552. The setting of the limiting pin 150 further limits the floating range, so that the floating range is kept within a preset value, which is 10-100 microns. The values ​​of the first gap 142 and the second gap 1552 can be adjusted according to actual needs. In this embodiment, the entire floating range cannot be infinitely large. At least during the guiding process, the guide post 152 can cooperate with the stamping die 16 or the bearing 17 below for guidance. Then, through a small range of floating, the floating suction assembly 15 can move downwards precisely, so that the suction head 151 enters the corresponding position.

[0058] Specifically, as shown in the attached document Figures 5-10As shown, there are two limit pins 150, which are arranged diagonally. The imaginary line connecting the two limit pins 150 and the imaginary line connecting the two guide posts 152 form an X-shaped line, that is, a cross line. In addition, those skilled in the art can adjust the number of limit pins 150 according to actual needs.

[0059] Specifically, there are four first-level height screws 156, which are distributed at the four corners.

[0060] Specifically, there are two second equal-height screws 157, and the two second equal-height screws 157 are arranged symmetrically.

[0061] Specifically, as shown in the attached document Figures 5-10 As shown, a first fixing member 211 is fixed to the base plate 154, and a steel ball 159 is fixed to the first fixing member 211. The first fixing member 211 has a groove that mates with the steel ball 159. The steel ball 159 is fixed in the groove, allowing only rolling. The steel ball 159 will not move relative to the base plate 154 along the Z-axis, nor will it move relative to the base plate 154 along the X or Y axes. The steel ball 159 can only roll relative to the first fixing member 211. The first fixing member 211 and the steel ball 159 form a modular fixation, improving the ease of assembly of the entire device; and, when the steel ball 159 is damaged, it can be quickly repaired and replaced. A second fixing member 212 is fixed to the mounting plate 14. The second fixing member 212 abuts against the steel ball 159. The strength of the second fixing member 212 is greater than the strength of the mounting plate 14, and when the second fixing member 212 is damaged, only the second fixing member 212 needs to be replaced. The steel ball 159 forms a sliding connection between the base plate 154 and the mounting plate 14. The first fixing member 211 and the second fixing member 212 are provided to improve the strength of the connection and prevent the steel ball 159 from rubbing against the base plate 154 and the mounting plate 14, thus improving their strength. When the mounting plate 14 moves downward, it drives the base plate 154 downward through the steel ball 159, achieving a linkage effect. In this embodiment, one first fixing member 211, one steel ball 159, and one second fixing member 212 form a group, and there are four groups in total. The four groups are respectively located at the center of the top surface of the base plate 154 near the front side, the center of the top surface of the base plate 154 near the rear side, the center of the top surface of the base plate 154 near the left side, and the center of the top surface of the base plate 154 near the right side. The four groups form a rhombus structure, which better achieves the balance between the base plate 154 and the mounting plate 14 and ensures stability at each position.

[0062] Specifically, as shown in the attached document Figures 5-10As shown, an elastic element 213 is provided between the mounting plate 14 and the floating plate 155. The elastic element 213 provides an elastic buffering effect between the mounting plate 14 and the floating plate 155. There are two elastic elements 213, which are symmetrically arranged. The elastic element 213 can be a spring, rubber, or other elastic material.

[0063] Specifically, as shown in the attached document Figures 5-10 As shown, the suction head 151 is fixed with elastic positioning pins 1511. The elastic positioning pins 1511 extend beyond the bottom surface of the suction head 151 and are elastically retractable. When the elastic positioning pins 1511 encounter an object, they retract into the suction head 151. In this embodiment, the elastic positioning pins 1511 cooperate with the metal sheet 20, which has holes for cooperating with the elastic positioning pins 1511. Here, there are two elastic positioning pins 1511. Alternatively, the bottom surface of the suction head 151 is provided with riveting grooves 1512 for riveting the metal sheet 20. The number of riveting grooves 1512 can be selected according to actual needs. The elastic positioning pins 1511 cooperate with the metal sheet 20 to achieve a positioning effect. The riveting groove 1512 is used when the metal sheet 20 is engaged with the semi-finished product. The semi-finished product has a protrusion on the side where it engages with the metal sheet 20. When the stripping rod 192 drives the entire floating suction assembly 15 toward the semi-finished product, the protrusion engages with the riveting groove 1512 to form the riveting of the metal sheet 20, thereby achieving the connection and fixation between the metal sheet 20 and the semi-finished product. When the suction head 151 is removed, the suction head 151 will not drive the metal sheet 20 to move.

[0064] Specifically, as shown in the attached document Figure 5 As shown, the base plate 154 has a fourth through hole 1541, and the side wall of the fourth through hole 1541 has a guide groove 1542. The suction head 151 passes through the mounting plate 14 and then through the fourth through hole 1541, extending downwards. The outer side wall of the suction head 151 has a guide rib 1513 that cooperates with the guide groove 1542. The guide rib 1513 plays a guiding role, preventing large-scale shaking. It should be noted that the guide rib 1513 and the guide groove 1542 do not abut against each other; there is still a gap between them, which allows the suction head 151 to have a floating effect.

[0065] Specifically, the number of floating suction components 15 connected to the mounting plate 14 can be one, two, or more. When there are two or more floating suction components 15, a circular array distribution is preferred, which can realize the simultaneous operation of stamping and stripping riveting. That is, the mounting plate 14 moves downward as a whole, one station performs the stamping operation, and another station performs the stripping and riveting operation. After the operation is completed, the empty suction head 151 is rotated to the top of the stamping station by the rotating mechanism 13, and the suction head 151 with the metal sheet 20 is rotated to the top of the support 17 with the semi-finished product. The cooperation of multiple sets of floating suction components 15 can improve the processing efficiency. In this embodiment, two floating suction components 15 are used as an example. The two floating suction components 15 are symmetrically arranged and connected to both ends of the mounting plate 14 respectively. The rotating mechanism 13 is connected to the central area of ​​the mounting plate 14, forming the effect of the rotating mechanism 13 driving the mounting plate 14 to rotate.

[0066] Specifically, as shown in the attached document Figures 2-10 As shown, when the second drive source 181 operates, it drives the pressure rod 182 to move towards the floating plate 155. The pressure rod 182 then drives the floating plate 155 downward along the Z-axis. The suction head 151 moves into the stamping cavity 161 of the stamping die 16, where it abuts against the metal sheet 20. At this time, the floating plate 155, the mounting plate 14, and the base plate 154 are fixed and will not float, ensuring force transmission and overall stability. The second drive source 181 continues to apply pressure, ensuring that the force applied to one side of the pressure rod 182 is greater than the force generated by stamping, i.e., the pressure above is greater than the stamping force below. This ensures that during processing, the upward stamping force will not damage the floating suction assembly 15, the second drive source 181, or the pressure rod 182. Here, the force applied by the second drive source 181 is a constant pressure.

[0067] Specifically, as shown in the attached document Figures 5-10As shown, there are two guide pillars 152, which are diagonally arranged, and the lower end of each guide pillar 152 is frustoconical or conical, serving a guiding effect. It should be noted that the stamping die 16 includes an upper die 162 and a lower die 163, with the stamping cavity 161 located between the upper die 162 and the lower die 163. The guide pillars 152 first cooperate with the upper die 162 to form a guiding effect. At this time, the lower end of the suction head 151 has not yet entered the stamping cavity 161. The lower end of the suction head 151 passes through the top surface of the upper die 162 and moves into the stamping cavity 161 along with the guiding effect of the guide pillars 152, thus allowing the suction head 151 to accurately enter the stamping cavity 161. In this embodiment, the stamping cavity 161 has openings at both the front and rear for conveying the strip 201. For example, the support 17 is provided with a mating post 171, which has a hole. The mating post 171 extends upward along the Z-axis and extends beyond the top surface of the semi-finished product. When the floating suction assembly 15 moves downward, the guide post 152 first engages with the mating post 171, and then the suction head 151 moves to abut against the semi-finished product. Here, the guide post 152 also plays a guiding role.

[0068] Specifically, the suction head 151 is provided with an air passage that cooperates with the suction nozzle 153. The air passage cooperates with the air tube to achieve the control effect of the suction nozzle 153. In this embodiment, the air tube connector 22 is provided on the mounting plate 14. One end of the air tube connector 22 is connected to the air passage of the suction head 151 through the air tube, and the other end of the air tube connector 22 cooperates with the external vacuum system. When the vacuum system is working, it creates a negative pressure, so that the suction nozzle 153 can achieve the vacuum adsorption effect. When the vacuum system stops working, the suction nozzle 153 does not have the vacuum adsorption effect. Here, the suction nozzle 153 is a precision suction nozzle 153. In addition, in order to facilitate the routing of air tubes, the air tube connector 22 can also be provided on other parts.

[0069] Specifically, as shown in the attached document Figures 2-4As shown, the rotating mechanism 13 includes a servo motor 131 and a reducer 132. The servo motor 131 and the reducer 132 cooperate, and the output end of the reducer 132 is linked to the mounting plate 14, driving the mounting plate 14 to rotate. Here, the servo motor 131 is inverted, meaning its output end faces the mounting plate 14. To save space, the mounting plate 23 has holes through which part of the servo motor 131 extends upwards. The housing of the reducer 132 is connected and fixed to the linkage plate 12. When the linkage plate 12 moves, the reducer 132 and the servo motor 131 also move. The cooperation between the servo motor 131 and the reducer 132 achieves a better driving effect. Compared to the instability of cylinder transmission, the servo motor 131 transmission is more stable. Furthermore, the inverted mounting of the servo motor 131 saves installation space and reduces the overall height. The reducer 132 provides a speed reduction effect, allowing for more precise control of the rotation angle. When there are two floating suction components 15, the rotating mechanism 13 controls the mounting plate 14 to rotate 180° each time, forming control between the two ends, that is, one station performs suction of metal sheet 20, and the other station performs riveting of metal sheet 20.

[0070] Specifically, as shown in the attached document Figures 2-4 As shown, the system also includes a support plate 24, a base 25, and a second guide shaft 26. The base 25 is located between the linkage plate 12 and the support plate 24. In this embodiment, the linkage plate 12 is located below the base 25, and the support plate 24 is located above the base 25. One end of the second guide shaft 26 is connected to the linkage plate 12, and the other end passes through the base 25 and connects to the support plate 24. Here, the base 25 is fixed, while the support plate 24 and the linkage plate 12 slide relative to the base 25. The second guide shaft 26 provides a guiding effect. The support plate 24, the base 25, and the linkage plate 12 work together to achieve the movement of the linkage plate 12. The first drive mechanism 11 drives the linkage plate 12 to move, and the support plate 24 provides a supporting and limiting effect, improving the overall stability of the drive. In this embodiment, there are four second guide shafts 26, which are distributed at the four corners of the support plate 24. These second guide shafts 26 are precision guide shafts.

[0071] Specifically, as shown in the attached document Figures 2-4 As shown, it also includes a fixing plate 23, a base 25 connected and fixed to the fixing plate 23, a support plate 24 located above the fixing plate 23, and a linkage plate 12 located below the fixing plate 23. The fixing plate 23 provides an overall fixing effect.

[0072] Specifically, it also includes four columns 27, which are connected to the fixing plate 23 respectively, thus providing a supporting and fixing effect. The stamping die 16 can be located in the cavity formed by the four columns 27, which facilitates the placement of the entire device.

[0073] Specifically, as shown in the attached document Figures 2-4 As shown, the second drive source 181 and the third drive source 191 are both fixed on the fixing plate 23. The fixing plate 23 has a fixing effect, making the drive more stable. Here, the second drive source 181 and the third drive source 191 are cylinders, oil cylinders or other drive structures.

[0074] Specifically, the first drive source 111 is fixed on the base 25, and the first drive rod 112 passes through the base 25, the fixing plate 23 and connects to the linkage plate 12.

[0075] Specifically, it also includes a control system, which controls the movements of components such as the first drive source 111, the second drive source 181, the third drive source 191, and the suction nozzle 153, thereby ensuring the effective operation of the entire rotary conveying device. This control system can be PLC-controlled or other control methods, such as a microcontroller. In addition, sensors can be installed at corresponding positions to determine whether the device is in position; and alarm devices can be installed to notify operators of device malfunctions. These alarm devices can be indicator lights or buzzers, etc.

[0076] Specifically, in this embodiment, the working process of the rotary conveying device is as follows: the strip 201 is inserted into the stamping cavity 161, the first drive source 111 is activated, the first drive rod 112 drives the linkage plate 12, the mounting plate 14, and the floating suction assembly 15 to move downward along the Z-axis, the guide column 152 cooperates with the stamping die 16, and the suction head 151 enters the stamping cavity 161 and abuts against the metal sheet 20. The second drive source 181 is activated, driving the pressure rod 182 to move toward the floating suction assembly 15. The pressure rod 182 first contacts the floating plate 15. The 5 parts are offset, and then the floating plate 155 moves downward, finally achieving a fixed state for the floating plate 155, mounting plate 14, and base plate 154. The stamping head stamps from bottom to top. After stamping, the suction nozzle 153 adsorbs the metal sheet 20. The second drive source 181 drives the pressure rod 182 to reset, and the first drive source 111 drives the suction head 151 to move upward along the Z-axis, so that the suction head 151 moves outside the stamping die 16. At this time, the stamping head and strip 201 also move, preparing for the next stamping action. The rotating mechanism 13 operates, driving the mounting plate 14 to rotate, causing the floating suction component 15 to rotate above the support 17. Then, the first drive source 111 drives the suction head 151 to move downward along the Z-axis, so that the suction head 151, which has picked up the metal sheet 20, moves to the support 17, and the metal sheet 20 is attached to the semi-finished product. After the attachment is completed, the suction nozzle 153 stops working, that is, there is no vacuum adsorption effect between the suction nozzle 153 and the metal sheet 20. The third drive source 191 drives the stripping rod 192 to move toward the floating suction assembly 15. The stripping rod 192 first abuts against the floating plate 155, and then drives the floating plate 155 to move downward, ultimately fixing the floating plate 155, mounting plate 14, and base plate 154. This creates a riveting impact effect, riveting the metal sheet 20 to the semi-finished product. After riveting, the third drive source 191 drives the stripping rod 192 to reset, and the first drive source 111 drives the suction head 151 to move upward along the Z-axis, creating a processing effect between the metal sheet 20 and the semi-finished product. The processed semi-finished product can then be gripped by a multi-axis robot for the next process. Thus, the entire rotary conveying device reciprocates, creating a conveying effect for the metal sheet 20.

[0077] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
