Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging module preparation equipment, in particular to a stamping equipment for packaging module preparation. BACKGROUND

[0002] At present, in the preparation process of packaging modules, metal structural parts such as conductive terminals and lead frames usually need to be formed by stamping equipment. The existing stamping equipment generally includes a workbench, upper and lower dies, and a driving cylinder. The metal plate is pressed by the die to form the required shape of the parts. However, in continuous stamping operation, the positioning accuracy of the metal plate directly affects the product quality. If the plate shifts during stamping, it may cause terminal deformation, size out-of-tolerance and other problems, affecting the subsequent packaging quality.

[0003] The existing stamping equipment uses simple pressing blocks or manual positioning methods to fix the plate, which is difficult to achieve stable and reliable clamping in high-speed continuous operation. On the one hand, it is difficult to completely prevent plate slippage by relying only on the friction force of the upper die when it is pressed down, especially when stamping large-size or thick plates, the risk of deviation is higher. On the other hand, the existing equipment lacks effective lateral limiting of the plate, which causes the plate to swing during conveying, affecting the feeding accuracy and stamping consistency.

[0004] In addition, the feeding mechanism of the existing stamping equipment is independently controlled from the stamping action, making it difficult to achieve precise positioning and feeding coordination. The feeding and positioning actions are not synchronized, which may cause insufficient plate dwell time in the stamping station or excessive feeding, affecting the stamping rhythm and forming quality. Therefore, there is an urgent need for a stamping equipment that can achieve multi-directional accurate positioning, automatic feeding and coordinated action to improve the processing precision and production efficiency of packaging module preparation.

[0009] Preferably, the connecting transmission assembly includes an intermittent structure, which is placed at the bottom of the connecting box and connected to the lower end of one side of the first pulley group. The bottom of the intermittent structure is connected to the second pulley group, and a rotating rod is connected to the front side of the second pulley group. The rotating rod is connected to the first bevel gear, and the first bevel gear is externally meshed with the second bevel gear, which is connected to one side of the first guide roller group. Preferably, the intermittent structure includes a connecting shaft, which is connected to the lower end of one side of the first pulley group, and the connecting shaft extends into the interior of the rotating housing and is rotatably connected.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention converts rotational motion into linear motion by setting a first limiting component, i.e., driven by a motor, through a linkage mechanism consisting of a rotating arm, a first connecting rod, a moving plate, a second connecting rod, a first pressing rod, and a second pressing rod. This drives the first pressing rod and the second pressing rod, which are hinged through a fixed rod, to open and close.

The action is precise and the clamping force is large.

[0011] 2. This invention sets up a second limiting component, which is linked to the first limiting component. When the moving plate of the first limiting component moves, the gear driven by the fixed rack rotates. The power is transmitted to the turntable through the first pulley group. The rotation of the turntable is converted into the opposing linear motion of the clamping plates through the push-pull arm, thereby clamping the plate from both sides. The mating strip, plug-in shaft and spring set on the clamping plate make the clamping both stable and adaptable to small thickness changes, preventing damage to the plate and achieving lateral limiting with both flexibility and precision.

[0012] 3. This invention sets up a connecting transmission component, in which the component takes the reverse motion generated during the operation of the second limiting component as input, and converts it into a unidirectional intermittent rotational output through an intermittent structure composed of a rotating shell, an arc plate, a spring plate and an inner ratchet disc. This output is then transmitted to the first guide roller group through a bevel gear set, driving the sheet metal to be fed out and fed into the processing area, ensuring that the feeding action only occurs after the positioning is released, ensuring that the entire stamping process is cyclical and orderly, with a high degree of automation.

Detailed Implementation

[0021] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1This invention provides a stamping device for preparing packaging modules, comprising a work frame 1, a receiving plate 2 fixed at the upper center of the work frame 1, columns 3 on all four sides of the receiving plate 2, the tops of the columns 3 connected to a top plate 4, a cylinder 5 installed at the upper center of the top plate 4, the lower end of the cylinder 5 connected to the center of a pressure plate 6, an upper template 7 detachably installed at the bottom of the pressure plate 6, and sleeves 8 on the upper side of the pressure plate 6, each sleeve 8 having a guide rod 9 inserted inside, the bottom of the guide rod 9 connected to the receiving plate 2, the guide rod 9 serving to guide the up and down movement of the pressure plate 6, ensuring the stamping process... To ensure the stability of the process, a lower template 10 is detachably installed in the middle of the upper end of the receiving plate 2, and a multi-directional limiting device 11 is also provided at the upper rear side of the receiving plate 2. The upper template completely covers the stamping area. When the cylinder 5 drives the upper template 7 to press down and close the mold, the front end of the upper template 7 can naturally cover and press the front area of ​​the plate, forming a front-to-back coordinating pressing effect with the multi-directional limiting device 11 on the rear side. This effectively prevents the front side of the plate from warping or deforming due to uneven force or material rebound during the stamping process, ensuring the stamping accuracy.

[0023] Please see Figure 2 In this embodiment, the multi-directional limiting device 11 includes a connecting box 111. The connecting box 111 is bolted to the upper rear side of the receiving plate 2. The front and rear sides of the upper end of the connecting box 111 are respectively provided with a first guide roller group 112 and a second guide roller group 113 for guiding and conveying metal plates. The left side of the connecting box 111 is connected to a first limiting component 114, and the lower pressing end of the first limiting component 114 is connected to a pressure strip 115 for pressing and fixing the plate before stamping to prevent displacement. The connecting box 111 is provided with a second limiting component 116, one end of which is connected to the first limiting component 114, and the other end is connected to the connecting transmission component 117. The connecting transmission component 117 is connected to the side of the first guide roller group 112.

[0024] Please see Figure 3 In this embodiment, the first limiting component 114 includes a connecting frame 1141, which is located on the side of the connecting box 111. A motor 1142 is installed inside the rear side of the connecting frame 1141. The output end of the motor 1142 is connected to a rotating arm 1143. The front side of the rotating arm 1143 is rotatably connected to a moving plate 1145 via a first connecting rod 1144. The moving plate 1145 is slidably disposed inside the connecting frame 1141. The upper rear end of the moving plate 1145 is connected to a second connecting rod 1145 via a second connecting rod 1144. Rod 1146 is rotatably connected to the first pressure rod 1147. A second pressure rod 1148 is provided above the first pressure rod 1147. Fixing rods 1149 are provided on the rear side of both the first pressure rod 1147 and the second pressure rod 1148. The fixing rods 1149 on both sides are fixedly connected to the upper end of the connecting frame 1141. Connecting strips 11410 are connected to the front side of both the first pressure rod 1147 and the second pressure rod 1148, and pressure strips 115 are connected to the bottom side of the connecting strips 11410.

[0025] Please seeFigures 4-5 In this embodiment, the second limiting component 116 includes a slider 1161, which is fixed to the side of the movable plate 1145. A rack 1162 is bolted to the outside of the slider 1161, and the rack 1162 meshes with a gear 1163. The top of the gear 1163 is connected to the turntable 1165 through a first pulley group 1164. Push-pull arms 1166 are hinged to the left and right sides of the top of the turntable 1165, and the other end of each push-pull arm 1166 is connected to a fixed plate 1167 on both sides. The fixed plate 1167 is connected to the two sides of the clamping plate 1168. The clamping plate 1168 is slidably installed on the left and right sides of the upper end of the support frame 1169. The bottom of the support frame 1169 is fixed inside the connecting box 111. Each clamping surface at the upper end of the clamping plate 1168 is provided with a mating strip 11610. The mating strip 11610 is inserted into the two sides of the mating shaft 11611, and the mating shaft 11611 slides in cooperation with the upper end of the clamping plate 1168. A spring 11612 is provided on the outside to provide cushioning and maintain the clamping force.

[0026] Please see Figure 6 In this embodiment, the connecting transmission assembly 117 includes an intermittent structure 1171, which is placed at the bottom of the connecting box 111 and connected to the lower end of the first pulley group 1164. The bottom of the intermittent structure 1171 is connected to the rotating rod 1173 through the second pulley group 1172. The upper end of the rotating rod 1173 is provided with a first bevel gear 1174, which meshes with a second bevel gear 1175. The second bevel gear 1175 is connected to the side of the first guide roller group 112.

[0027] Please see Figure 7 In this embodiment, the intermittent structure 1171 includes a connecting shaft 11711, which is connected to the lower end of the first pulley group 1164 and extends into the rotating housing 11712 for rotatable connection. An arc-shaped plate 11713 is provided on one side of the rotating housing 11712. One side of the arc-shaped plate 11713 is connected by a spring plate 11714, and the other side is engaged in an inner ratchet disc 11715, which is rotatably disposed within the rotating housing 11712. The first guide roller group 112 is connected to the second pulley group 1172 via a shaft, thus enabling unidirectional intermittent transmission: when the connecting shaft 11711 rotates in the forward direction, the arc plate 11713 slides within the inner ratchet disk 11715 without driving it to rotate; when the connecting shaft 11711 rotates in the reverse direction or stops, the spring plate 11714 pushes the arc plate 11713 to clamp the inner ratchet disk 11715, thereby transmitting torque and thus realizing the intermittent rotation of the first guide roller group 112.

[0028] The working principle of this embodiment is as follows; First, the metal sheet is fed into the feed end of the equipment. When it comes into contact with the first guide roller group 112 and the second guide roller group 113, the metal sheet is stably guided into the stamping position. At this stage, the main function of the first guide roller group 112 and the second guide roller group 113 is to smoothly convey the sheet and provide it with initial conveying guidance. When the metal sheet moves to the preset stamping station, the multi-directional limiting device 11 is activated. The motor 1142 in the first limiting component 114 drives the rotating arm 1143 to rotate. Through the linkage mechanism composed of the first connecting rod 1144, the moving plate 1145 and the second connecting rod 1146, the rotational motion is converted into the downward pressing action of the first pressing rod 1147 and the second pressing rod 1148. In this way, the first pressing rod 1147 and the second pressing rod 1148 eventually drive the pressing strip 115 at the bottom of the connecting strip 11410 to move downward, thereby firmly pressing the upper surface of the metal sheet and effectively preventing the sheet from shifting during stamping. During the operation of the first limiting component 114, the slider 1161 and rack 1162, which are fixedly connected to the moving plate 1145, move synchronously. The rack 1162 drives the gear 1163 meshing with it to rotate. The power is transmitted to the turntable 1165 through the first pulley group 1164. The rotation of the turntable 1165 is converted into the lateral linear motion of the fixed plate 1167 through the two push-pull arms 1166, thereby driving the clamping plates 1168 on both sides to move towards each other and clamp the metal plate from the left and right sides. The spring 11612 at the upper end of the clamping plate 1168 provides a buffer for the clamping action, ensuring that it can be fixedly limited without damaging the metal plate. Thus, the plate is fixedly limited on the upper surface and the left and right surfaces, ensuring that the metal plate is accurately positioned for stamping and reducing the probability of stamping deviation of the metal plate. Subsequently, the control system activates cylinder 5, which drives the pressure plate 6 to descend steadily along the guide rod 9. The upper template 7 installed at the bottom of the pressure plate 6 then closes with the lower template 10 on the receiving plate 2. The upper template 7 completely covers the entire stamping area. Therefore, during its downward pressing process, it not only cooperates with the lower template 10 to stamp the middle of the sheet metal, but the front end of the upper template 7 also naturally presses down on the front area of ​​the sheet metal. At this time, from the perspective of force analysis, the sheet metal is in a state of all-round constraint. Its rear side is pressed by the pressure strip 115, its left and right sides are clamped by the clamping plate 1168, and its middle and front sides are firmly pressed down by the closing force of the upper template 7 and the lower template 10. Due to the physical coverage of the upper template 7, it is difficult for the front side of the sheet metal to lift up at the most critical moment of stamping, thus ensuring the stability and forming accuracy of the stamping process. After the stamping action is completed, the cylinder 5 drives the upper template 7 to retract. Then, the motor 1142 of the first limiting component 114 reverses, causing the pressure bar 115 to lift. At the same time, the clamping plate 1168 of the second limiting component 116 also loosens. At this time, the reverse rotation of the first pulley group 1164 is transmitted to the intermittent structure 1171 through the connecting shaft 11711. Inside the intermittent structure 1171, the rotating shell 11712 rotates in the reverse direction. The spring plate 11714 pushes the arc plate 11713 to engage with the tooth groove of the inner ratchet disc 11715, thereby driving the inner ratchet disc 11715 and the second pulley group 1172 connected to it to rotate a certain angle. The power is then transmitted back to the first guide roller group 112 through the rotating rod 1173, the first bevel gear 1174 and the second bevel gear 1175, driving it to rotate and sending out the stamped plate in a step-by-step manner, while sending the new plate area to be processed into the stamping station.
