Description

Technical Field

[0001] The present application relates to the technical field of kettle processing auxiliary equipment, and in particular to a cutting device for a glue injection port of a kettle chassis. Background Art

[0002] After the chassis of the electric heating kettle is injection molded, a round hole-shaped cutout needs to be opened on the chassis through a stamping device for later assembly of the power supply and heating element, thereby achieving the effect of powering and heating the kettle. There is a convex step on the chassis, which can play a positioning effect when placing the kettle in the later stage. The round hole-shaped cutout needs to be opened at the center of the convex step.

[0003] In the related art, the chassis molded by the injection molding equipment are stacked in batches in a material box, and the operator moves the material box to the location of the stamping equipment for subsequent punching operations. The operator takes the chassis from the material box and places it on the stamping equipment for punching. After the incision is formed on the chassis, the chassis is removed from the stamping equipment.

[0004] In view of the above-mentioned related technologies, a robot arm is usually used to replace manual work in the production process of the chassis. At the injection molding equipment, the robot arm can clamp the uncut chassis molded by injection molding and send it into the material box. In order to improve the degree of automation in the chassis production process, it is necessary to provide a cutting device at this stage so that it can cooperate with the robot arm, thereby improving the efficiency of the entire chassis processing process. Utility Model Content

[0005] In order to improve the degree of automation in the chassis production process, the present application provides a cutting device for the glue injection port of the kettle chassis.

[0006] The present application provides a cutting device for the glue injection port of the kettle chassis, which adopts the following technical solution:

[0007] The invention comprises a mounting platform and a stamping device arranged on the mounting platform, wherein the stamping device has a frame and a stamping chamber is formed in the frame, wherein a stamping die seat for placing a chassis is arranged in the stamping chamber, and further comprises a conveying device, wherein the conveying device has a placement area for a mechanical arm to place the chassis and a transport clamp for clamping the chassis, wherein the transport clamp transports the chassis on the placement area to the stamping die seat

[0008] By adopting the above technical solution, the conveying device first provides a placement area for the kettle chassis. When the robot arm places the kettle chassis on the conveying device, the transport clamp transports the chassis to the stamping device for subsequent cutting processing, realizing the automation of the chassis from placement to stamping, which not only reduces the dependence on manual operation, but also improves the stability and efficiency of the production process. The precise control of the robot arm and the transport clamp allows the chassis to be accurately placed on the stamping die base, ensuring the accuracy and consistency of the cutting position of each chassis.

[0009] Furthermore, the plane where the central axis of the stamping die base and the central axis of the placement area are located is parallel to the depth direction of the stamping chamber.

[0010] By adopting the above technical solution, the central axis of the placement area and the central axis of the stamping die base are parallel to the depth direction of the stamping chamber. Such an arrangement can provide the shortest straight-line stroke for the conveying device to convey the chassis, and can also ensure that when the chassis moves from the placement area to the stamping die base, the chassis can be accurately aligned with the center position of the stamping die base, thereby improving the positioning accuracy of the chassis and ensuring the accuracy of the incision position.

[0011] Furthermore, the stamping die base is provided with a limiting protrusion matched with the convex step of the chassis, and the transport clamp is provided with a lifting mechanism, and the lifting height of the clamp by the lifting mechanism is greater than / equal to the height of the limiting protrusion.

[0012] By adopting the above technical solution, a limiting protrusion that matches the convex step of the chassis is set on the stamping die base to prevent the chassis from shifting or sliding during the stamping process, ensuring that the chassis can be accurately positioned when placed on the stamping die base, improving the position stability of the chassis during the stamping process, and thus ensuring the accuracy of the incision position. The lifting mechanism on the transport clamp can ensure that when the chassis is clamped, the lifting height of the clamp is greater than or equal to the height of the limiting protrusion. When the chassis is transferred from the transport clamp to the stamping die base, the chassis and the die base can be prevented from interfering with each other, avoiding collision or damage to the chassis.

[0013] Furthermore, the conveying device includes a motor screw disposed on the mounting platform and used for driving the transport clamp to move horizontally.

[0014] By adopting the above technical solution, the motor screw is arranged on the mounting table, which can control the horizontal movement of the transport clamp, so that the transport clamp can move to the side of the stamping device after clamping the chassis. The motor screw has a fast response speed and smooth movement, and can quickly and accurately complete the chassis transportation task, and can ensure the accuracy and reliability of the chassis during transportation.

[0015] Furthermore, the conveying clamp comprises two symmetrically arranged clamp bodies and an opening and closing driving member for driving the two clamp bodies to move closer to or away from each other.

[0016] By adopting the above technical solution, the two symmetrically arranged clamping jaw bodies can maintain balance when clamping and transporting the chassis, avoiding unnecessary torque or stress, thereby ensuring the stability and reliability of the operation. The opening and closing drive member is used to drive the two clamping jaw bodies to move closer to or farther away from each other. The two clamping jaw bodies move closer to each other and clamp the chassis. When the chassis is transported to the specified position, the two clamping jaw bodies move away from each other and release the chassis.

[0017] Furthermore, it also includes an infrared detection component disposed at a position adjacent to the conveying device, the infrared detection component is located on a side away from the stamping device and is electrically connected to the opening and closing driving member;

[0018] When the infrared detection component detects that the chassis is placed between the two clamping jaw bodies, the opening and closing driving member drives the two clamping jaw bodies to clamp the chassis.

[0019] By adopting the above technical solution, the infrared detection component can automatically detect whether the chassis has been placed between the two clamping jaws. Once the chassis is detected to be in place, the opening and closing drive will automatically drive the clamping jaws to clamp the chassis and transport it, further improving the automation of the entire chassis transportation and processing and reducing the need for manual intervention.

[0020] Furthermore, the stamping device has a stamping cutter head and a hydraulic cylinder for driving the stamping cutter head, the stamping cutter head is coaxially arranged above the stamping die base, and the stamping cutter head is provided with a pressure plate assembly for pressing the chassis at one end close to the stamping die base.

[0021] By adopting the above technical solution, the stamping device consists of a stamping cutter head and a hydraulic cylinder for driving the stamping cutter head. The hydraulic cylinder serves as a power source to provide stable pressure and power to ensure that the stamping cutter head can perform stamping operations accurately and efficiently. The stamping cutter head is coaxially arranged above the stamping die base to ensure that the centering accuracy between the cutter head and the die base is high during the stamping process, thereby improving the stamping accuracy and product quality. At one end of the stamping cutter head close to the stamping die base, a pressure plate assembly is provided to press the chassis to prevent the chassis from moving or deforming during the stamping process, thereby ensuring the stability and safety of the stamping process.

[0022] Furthermore, the pressure plate assembly includes a pressure plate, a plurality of positioning columns and a plurality of elastic members, the abutment plate is sleeved on the outside of the stamping cutter head and fixedly connected to the outer wall of the stamping cutter head, the frame is provided with a mounting plate for installing the positioning columns, the positioning columns are circumferentially arranged around the stamping cutter head, one end of each positioning column is fixedly connected to the top of the abutment plate, and the end of each positioning column away from the end connected to the abutment plate is penetrated and slidably installed on the mounting plate, the elastic members are sleeved on the outer wall of each positioning column one by one, and the two ends of each elastic member are abutted between the abutment plate and the mounting plate.

[0023] By adopting the above technical solution, the pressure plate is arranged outside the punching cutter head and fixedly connected to the outer wall of the punching cutter head. During the punching process, the pressing chassis is pressed against the upper surface of the chassis to ensure that the chassis remains stable and does not move or deform. On the other hand, the position of the pressure plate and the punching cutter head below is relatively fixed, which is equivalent to limiting the depth of the punching cutter head into the chassis to prevent the punching from not being in place. The positioning column and the elastic member are circumferentially arranged around the punching cutter head. When the punching cutter head moves downward, the elastic member is compressed to provide an upward reaction force, thereby providing a certain buffering effect when the pressure plate is impacted to protect the chassis and the punching cutter head.

[0024] Furthermore, a feed hole for passing waste is provided at the center of the stamping die seat, and a receiving interface for receiving waste is provided below the stamping device on the mounting platform, and the receiving interface is aligned with the feed hole.

[0025] By adopting the above technical solution, the material discharge through hole enables the waste generated during the stamping process to be discharged smoothly from the die base. The mounting platform is provided with a receiving interface below the stamping device and is aligned with the material discharge through hole of the die base, so that the waste discharged from the die base can be received and collected.

[0026] Furthermore, the mounting platform is provided with a waste outlet on the side wall, and the mounting platform is provided with a waste channel inside for guiding the waste to slide down, and two ends of the waste channel are respectively connected to the feed through hole and the waste outlet.

[0027] By adopting the above technical solution, a waste outlet is opened on the side wall of the receiving box, and the waste is collected centrally. At the same time, it is convenient for operators or automated equipment to clean the waste in the receiving box regularly.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Through the coordinated work of the robotic arm, transport gripper and infrared detection components, the chassis is automated from placement to stamping, reducing dependence on manual operation, improving the stability and efficiency of the production process, and automated operation reduces errors caused by human factors, ensuring the accuracy and consistency of the production process;

[0030] 2. The central axis of the placement area and the central axis of the stamping die base are parallel to the depth direction of the stamping chamber, providing the shortest linear travel for the transportation of the chassis, while ensuring that the chassis can be accurately aligned with the center position of the stamping die base, improving the positioning accuracy of the chassis and the accuracy of the incision position. The lifting mechanism on the transport clamp and the limit protrusion design on the stamping die base prevent the chassis from deflecting or sliding during transportation and stamping, and improve the position stability of the chassis during the stamping process;

[0031] 3. A material discharge through hole is opened on the stamping die base, and a receiving interface and a waste outlet are opened on the mounting table and connected by a waste channel to realize automatic collection and centralized treatment of waste during the stamping process.

[0040] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 And embodiments, the present application is further described in detail.

[0041] The embodiment of the present application discloses a cutting device for a glue injection port of a kettle chassis. The words such as "upper" and "lower" used to express the positional relationship described in the embodiment are all determined with reference to the placement and installation position of the cutting device for the glue injection port of the kettle chassis when it is in normal use.

[0042] Reference Figure 1 The cutting equipment for the glue injection port of the kettle chassis includes a punching device 1 for cutting the chassis 0, a conveying device 2 for conveying the chassis 0 to the position of the punching device 1, and a mounting table 3, wherein the punching device 1 and the conveying device 2 are both located above the mounting table 3.

[0043] Reference Figure 2 The chassis 0 is a round pancake-shaped structure formed by an injection molding machine. The chassis 0 has a coaxially arranged convex step 01. When the kettle is placed on the chassis 0, the convex step 01 can limit the kettle to a certain extent. The cutout 02 is in the shape of a round hole and is located at the center of the convex step 01. The cutout 02 can be used for assembling the heating element later.

[0044] Reference Figure 3 and Figure 4 The punching device 1 has a frame 11 and a punching chamber 111 for punching operation is formed on the frame 11.

[0045] Reference Figure 5 and Figure 6A stamping die seat 12 and a stamping cutter head 13 are provided in the stamping chamber 111. A limiting protrusion 121 matching the convex step 01 of the chassis 0 is coaxially and integrally provided on the stamping die seat 12. When the chassis 0 is placed on the stamping die seat 12, the limiting protrusion 121 can form a clamping effect on the chassis 0 to prevent the chassis 0 from radial movement during the punching process.

[0046] The punching cutter head 13 is arranged directly above the punching die base 12 . The punching device 1 is provided with a hydraulic cylinder 14 for driving the punching cutter head 13 . The punching cutter head 13 is driven by the hydraulic cylinder 14 to move up and down and perform punching operations.

[0047] Reference Figure 1 and Figure 5 In this embodiment, the punching cutter head 13 is provided with a pressure plate assembly 15 at one end close to the punching die base 12, and the pressure plate assembly 15 includes a pressure plate 151, a plurality of positioning posts 152 and a plurality of elastic members 153. The pressure plate 151 is sleeved on the outside of the punching cutter head 13 and fixedly connected to the outer wall of the punching cutter head 13, and a mounting plate 112 for mounting the positioning posts 152 is provided on the frame 11. In this embodiment, the number of the positioning posts 152 is preferably four, and the elastic members 153 are arranged one by one with the positioning posts 152. Each positioning column 152 is arranged circumferentially around the stamping cutter head 13, one end of each positioning column 152 is fixedly connected to the top of the abutment plate, and the end of each positioning column 152 away from the end connected to the pressure plate 151 is passed through and slidably installed on the mounting plate 112, and each elastic member 153 is correspondingly sleeved on the outer wall of each positioning column 152 and the two ends of each elastic member 153 are abutted between the abutment plate and the mounting plate 112.

[0048] Reference Figure 3 and Figure 7 The conveying device 2 includes a conveying track 21 and a conveying jaw 22 slidably mounted on the conveying track 21, and the conveying track 21 is arranged between the stamping device 1 and the injection molding device 5. The conveying jaw 22 includes a conveying base 221, an opening and closing driving member 223, a lifting mechanism 224 and two symmetrically arranged jaw bodies 222.

[0049] The transport base 221 is installed on the conveying track 21 and can slide along the length direction of the conveying track 21. The opening and closing drive member 223 is installed on the transport base 221. The opening and closing drive member 223 in this embodiment is preferably two cylinders with opposite driving directions. The two clamping jaw bodies 222 are respectively installed on the side of the opening and closing drive member 223 close to the stamping device 1.

[0050] Reference Figure 5 and Figure 6Since the limiting protrusion 121 on the stamping die base 12 has a certain height, the chassis 0 needs to be lifted by the lifting mechanism 224, and the lifting height of the chassis 0 by the lifting mechanism 224 is greater than the height of the limiting protrusion 121. The lifting mechanism 224 includes two lifting cylinders with relatively stable driving force, and the lifting mechanism 224 is installed above the opening and closing driving member 223.

[0051] The two clamp bodies 222 and the conveying track 21 together form a placement area 211 for placing the chassis 0 to be punched. The plane where the central axis of the stamping die base 12 and the central axis of the placement area 211 are located is parallel to the depth direction of the stamping chamber 111, thereby ensuring that the conveying stroke of the conveying track 21 is the shortest straight-line distance.

[0052] Reference Figure 3 and Figure 6 A motor screw 23 for driving the transport base 221 is provided under the conveying track 21. The motor screw 23 includes a driving motor 231 and a screw 232. The driving motor 231 is fixedly connected to the side of the mounting table 3 away from the stamping device 1. A layout groove 35 for arranging the screw 232 is opened on the mounting table 3 along the length direction. The screw 232 passes through the mounting table 3 and the conveying base from the side of the mounting table 3 away from the stamping device 1. The screw 232 is installed in the layout groove 35 and is threadedly matched with the transport base 221, thereby driving the transport base 221 to approach or move away from the stamping device 1.

[0053] Reference Figure 3 and Figure 6 In this embodiment, an infrared detection component 24 is further provided at a position adjacent to the conveying device 2. The infrared detection component 24 is located on a side away from the punching device 1, and the infrared detection component 24 is electrically connected to the opening and closing driving member 223. When the infrared detection component 24 detects that the chassis 0 is placed between the two clamping jaw bodies 222, the opening and closing driving member 223 drives the two clamping jaw bodies 222 to clamp the chassis 0.

[0054] Reference Figure 3 and Figure 5The stamping die base 12 is provided with a material discharge hole 122 at the center axis position, and the mounting platform 3 is provided with a receiving port 31 for receiving waste material below the stamping device 1, and the receiving port 31 is aligned with the material discharge hole 122. The mounting platform 3 is provided with a waste outlet 32 ​​on the side wall, and a waste channel 33 is provided inside the mounting platform 3. The two ends of the waste channel 33 are respectively connected to the material discharge hole 122 and the waste outlet 32, and the waste channel 33 is inclined to guide the waste material to slide down. A waste box 34 is provided at an adjacent position of the mounting platform 3 below the waste outlet 32, and the circular waste pieces punched out by the stamping cutter head 13 fall through the material discharge hole 122 and enter the waste channel 33 from the receiving port 31. The waste channel 33 guides the waste material to fall from the waste outlet 32 ​​and enter the waste box 34, which is convenient for the unified collection and centralized treatment of the waste material.

[0055] The implementation principle of the incision device for the injection port of the kettle chassis of the embodiment of the present application is as follows: the mechanical arm 4 grabs the uncut chassis 02 molded by injection molding on the injection molding equipment 5, and places the chassis 0 in the placement area 211 formed between the conveying track 21 and the two clamping claw bodies 222. The infrared detection component 24 is electrically connected to the opening and closing drive member 223. The infrared detection component 24 detects that the chassis 0 enters the placement area 211, and the opening and closing drive member 223 drives the two clamping claw bodies 222 to approach each other to clamp the chassis 0. The lifting mechanism 224 lifts the opening and closing drive member 223 so that the height of the chassis 0 can be higher than the height of the upper limit protrusion 121 of the stamping die base 12 to avoid mutual interference. The motor screw 23 is installed in the arrangement groove 35 of the mounting table 3 and is threadedly matched with the transport base 221, thereby driving the transport base 221 to move horizontally toward the stamping device 1. When the convex step 01 of the chassis 0 is aligned with the limiting protrusion 121 on the stamping die base 12 , the transport clamp 22 falls and releases the chassis 0 , and stably places the chassis 0 on the stamping die base 12 .

[0056] The punching head 13 punches the chassis 0 from top to bottom, and the pressure plate assembly 15 on the punching head 13 presses the chassis 0 to prevent the chassis 0 from radial displacement, and the elastic member 153 provides a buffering effect. The chassis 0 with the cut 02 completed is clamped by the robot arm 4 and transported to a predetermined area for placing the finished chassis 0. The disc-shaped waste left by the punching enters the receiving interface 31 through the material discharge through hole 122, and falls into the waste box 34 through the waste outlet 32 ​​under the guidance of the waste channel 33, which is convenient for unified collection and centralized treatment.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
