Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a linear feeding device for stamping discs. Background Technology

[0002] In the stamping process of metal blanks, especially in the automated stamping production of small precision parts such as battery terminals, the feeding device is a key link in achieving automated continuous operation. Currently, the commonly used feeding method in the industry is as follows: the blank is gripped by an openable robotic arm, and then a servo motor drives a linear guide module to move the robotic arm in reciprocating linear motion, transporting the blank from the pick-up position to the mold cavity. After stamping is completed, the robotic arm retracts and resets, ready for the next feeding. Some feeding devices also adopt a gantry-type multi-degree-of-freedom robotic arm structure, using linear motion modules in the X, Y, and Z directions to achieve clamping, lifting, and conveying actions. In addition, there are also feeding methods that use suction cup-type robotic grippers in conjunction with long, thin robotic arms for material transfer.

[0003] The existing feeding devices described above have the following shortcomings in practical applications:

[0004] First, the structure of an openable robotic arm is relatively complex. Existing robotic arms typically require finger cylinders or pneumatic devices to achieve the opening and closing of the grippers. They also need to be equipped with multiple drive components such as lifting cylinders and transfer cylinders. The number of parts is large, making assembly and maintenance difficult.

[0005] Secondly, electrical components experience accelerated wear and tear under high-intensity working conditions. Since the gripping, lifting, and conveying actions of the robotic arm all rely on the coordinated control of electrical components such as cylinders, solenoid valves, and sensors, these components are in a high-frequency operating state for a long time during continuous high-speed stamping operations, which can easily lead to fatigue failure or response delay, affecting the stability of feeding and production cycle.

[0006] Third, the stamping speed of existing feeding devices is limited. The complex reciprocating motion involves multiple action steps such as clamping, lifting, conveying, lowering, releasing, and resetting. The motion sequence is complex, and each feeding cycle takes a long time, making it difficult to meet the needs of high-speed stamping production.

[0007] Fourth, the equipment is large in size and requires significant capital investment. To meet the movement space and stamping load requirements of the feeding robot, existing solutions often require large-tonnage punch presses (such as 300T class), which occupy a large space and have high initial investment costs.

[0008] Now, a novel linear feeding device for biscuit stamping is proposed to solve the above problems. Summary of the Invention

[0009] The purpose of this invention is to provide a linear feeding device for biscuit stamping, so as to solve the problems of complex structure and high cost of existing feeding devices mentioned in the background art.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a linear feeding device for slab stamping, comprising a bottom support plate and a self-opening clamping assembly, wherein four sets of guide columns are fixedly connected at the middle position of the top of the bottom support plate, a lower die is provided above the bottom support plate, an upper die is provided above the lower die, and linear module bodies are respectively arranged laterally at the front and rear ends of the top of the bottom support plate.

[0011] The self-opening clamping assembly includes two sets of positioning plates, which are fixedly connected to the middle positions of the front and rear ends of the bottom support plate, respectively. Two sets of first guide rails are longitudinally fixedly installed at the middle position of the top of the bottom support plate. Trapezoidal sliders are respectively provided at the front and rear ends of the lower mold. Two sets of springs are movably installed between the positioning plates and the trapezoidal sliders. Two sets of second guide rails are longitudinally fixedly installed on both sides of the top of the bottom support plate. Four sets of linear module translation sliders are fixedly connected to the bottom end of the linear module body. Linear module matching sliders are slidably connected to the outside of the linear module body. Inserts that cooperate with the trapezoidal sliders are fixedly connected to both ends of the lower mold.

[0012] As a further technical solution of the present invention, the four sets of guide pillars respectively penetrate through the four corners of the lower mold.

[0013] As a further technical solution of the present invention, the lower mold and the guide post are in sliding fit.

[0014] As a further technical solution of the present invention, the vertical center lines of the bottom bearing plate, the lower mold, and the upper mold coincide.

[0015] As a further technical solution of the present invention, the positioning plates are symmetrically distributed about the vertical center line of the bottom bearing plate.

[0016] As a further technical solution of the present invention, the first guide rail and the trapezoidal slider are slidably fitted together, the top inclined surface of the trapezoidal slider and the bottom end of the lower mold are in contact, and the trapezoidal slider and the lower mold form a sliding fit.

[0017] As a further technical solution of the present invention, the second guide rail and the linear module translation slider are slidably engaged, and the main body of the linear module can slide back and forth along the second guide rail through the linear module translation slider.

[0018] As a further technical solution of the present invention, the ball screw inside the linear module body passes through the interior of the matching slider of the linear module, and the matching slider of the linear module and the ball screw inside the linear module body form a rolling friction fit.

[0019] As a further technical solution of the present invention, a mechanical gripper mounting plate is fixedly connected to the outer side of the slider of the linear module, and a fixed gripper is fixedly installed on the inner side of the mechanical gripper mounting plate.

[0020] As a further technical solution of the present invention, the bottom end of the fixed gripper and the top end of the linear module body are 1-3 mm apart.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the linear feeding device for cake stamping not only realizes automated linkage feeding, but also significantly reduces equipment cost and maintenance difficulty;

[0022] (1) By setting up a bottom support plate, guide pillars, lower mold, upper mold, linear module body and self-opening clamping components, the physical linkage of mold lifting and trapezoidal slider is realized to replace the complex opening and closing action of traditional robotic gripper. In specific operation, when the upper mold closes with the lower mold, the lower mold moves down and pushes the trapezoidal slider to slide outward along the first guide rail and compress the spring through the insert. At the same time, it drives the linear module body to slide backward along the second guide rail to avoid the stamping area. After stamping is completed, the upper mold resets upward, the spring releases and resets, pushes the trapezoidal slider to slide inward and drives the lower mold to move upward. At the same time, the linear module body drives the linear module matching slider to slide forward, driving the fixed gripper on the mechanical gripper mounting plate to clamp and linearly transport the material to the next station, completing the continuous operation of "mold closing and avoiding - mold opening and clamping - linear feeding". In this process, through the coordinated operation of inserts, trapezoidal sliders, and springs, the complex cylinders, solenoid valves, and other electrical components used for gripper opening, lifting, and transfer in traditional solutions are eliminated. This significantly reduces the failure and wear of electrical components under high-intensity, high-frequency working environments, simplifies the structure, and reduces maintenance costs. At the same time, the fixed gripper does not require opening and closing actions when gripping materials, simplifying the complex multi-stage reciprocating motion of traditional solutions into a single motion, effectively improving the stamping rate. In addition, this device eliminates the independent large-span motion space required by external robotic arms, adopting a compact integrated design that allows the tonnage of the matching punch press to be reduced from the traditional 300T class to about 200T class. While ensuring the processing accuracy of complex formed products, it significantly reduces the equipment footprint and lowers the initial equipment investment. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Please refer to Figure 1-6 A linear feeding device for stamping biscuit material includes a bottom support plate 1 and a self-opening clamping assembly 2. Four sets of guide columns 4 are fixedly connected at the middle position of the top of the bottom support plate 1. A lower die 3 is arranged above the bottom support plate 1, and an upper die 6 is arranged above the lower die 3. A linear module body 5 is arranged horizontally at the front and rear ends of the top of the bottom support plate 1.

[0032] Please see Figure 1-6 A linear feeding device for biscuit stamping also includes a self-opening and closing clamping assembly 2. The self-opening and closing clamping assembly 2 includes two sets of positioning plates 201, which are fixedly connected to the middle positions of the front and rear ends of the bottom support plate 1. Two sets of first guide rails 202 are longitudinally fixedly installed at the middle position of the top of the bottom support plate 1. Trapezoidal sliders 203 are respectively provided at the front and rear ends of the lower die 3. Two sets of springs 204 are movably installed between the positioning plates 201 and the trapezoidal sliders 203. Two sets of second guide rails 205 are longitudinally fixedly installed on both sides of the top of the bottom support plate 1. Four sets of linear module translation sliders 206 are fixedly connected to the bottom end of the linear module body 5. A linear module matching slider 207 is slidably connected to the outside of the linear module body 5. Inserts 7 that cooperate with the trapezoidal sliders 203 are fixedly connected to both ends of the lower die 3.

[0033] Four sets of guide pillars 4 pass through the four corners of the lower mold 3. The lower mold 3 and guide pillars 4 are slidably fitted. The vertical center lines of the bottom support plate 1, lower mold 3, and upper mold 6 coincide. The positioning plates 201 are symmetrically distributed about the vertical center line of the bottom support plate 1. The first guide rail 202 and trapezoidal slider 203 are slidably fitted. The top inclined surface of the trapezoidal slider 203 is in contact with the bottom end of the lower mold 3. The insert 7, trapezoidal slider 203, and lower mold 3 form a sliding fit. The second guide rail 205 and linear module translation slider 206 are slidably fitted. The linear module body 5 passes through the straight... The linear module translation slider 206 can slide back and forth along the second guide rail 205. The ball screw inside the linear module body 5 passes through the interior of the linear module matching slider 207. The linear module matching slider 207 and the ball screw inside the linear module body 5 form a rolling friction fit. A mechanical gripper mounting plate 208 is fixedly connected to the outer side of the linear module matching slider 207. A fixed gripper 209 is fixedly installed on the inner side of the mechanical gripper mounting plate 208. The bottom end of the fixed gripper 209 and the top end of the linear module body 5 are 1-3mm apart.

[0034] Specifically, such as Figure 1-6 As shown, when the upper mold 6 closes with the lower mold 3 downwards, the lower mold 3 moves downwards and pushes the trapezoidal slider 203 to slide outwards along the first guide rail 202 through the insert 7, compressing the spring 204. At the same time, it drives the linear module body 5 to slide backwards along the second guide rail 205 to avoid the stamping area. After stamping is completed, the upper mold 6 returns to its original position upwards, and the spring 204 releases and returns to its original position, pushing the trapezoidal slider 203 to slide inwards and driving the lower mold 3 to move upwards. At the same time, the linear module body 5 drives the linear module matching slider 207 to slide forwards, driving the fixed gripper 209 on the mechanical gripper mounting plate 208 to clamp and linearly transport the material to the next station.

[0035] Working Principle: In use, when the upper mold 6 closes with the lower mold 3, the lower mold 3 moves downward and pushes the trapezoidal slider 203 outward along the first guide rail 202 via the insert 7, compressing the spring 204. Simultaneously, the linear module body 5 slides backward along the second guide rail 205 to avoid the stamping area. After stamping, the upper mold 6 returns to its original position, and the spring 204 releases and pushes the trapezoidal slider 203 inward, causing the lower mold 3 to move upward. At the same time, the linear module body 5 drives the linear module's matching slider 207 to slide forward, causing the fixed gripper 209 on the mechanical gripper mounting plate 208 to clamp and linearly transport the material to the next workstation, completing the continuous operation of "mold closing and avoiding—mold separation and clamping—linear feeding." During this process, the insert 7 and the trapezoidal slider 203... The coordinated operation of 03 and spring 204 eliminates the need for complex cylinders, solenoid valves, and other electrical components used in traditional solutions for gripper opening, lifting, and transfer. This significantly reduces the failure rate of electrical components under high-intensity, high-frequency operating conditions, simplifies the structure, and lowers maintenance costs. Simultaneously, the fixed gripper 209 eliminates the need for opening and closing movements when gripping materials, simplifying the complex multi-stage reciprocating motion of traditional solutions into a single motion, effectively increasing the stamping rate. Furthermore, this device eliminates the need for a separate, large-span movement space required by an external robotic arm, adopting a compact integrated design that allows the tonnage of the matching punch press to be reduced from the traditional 300T class to approximately 200T class. While ensuring the processing accuracy of complex formed products, this significantly reduces the equipment's footprint and lowers initial equipment investment.
