[0037] Example

[0038] like Figures 1 to 9 As shown, this utility model proposes a high-efficiency chip baking device, including a base frame 1, and further comprising: a feeding assembly 2, a clamping and conveying assembly 4, a heating assembly 3, a pushing assembly 5, a discharging and waiting assembly 6, and a material box placement assembly 7, which are sequentially connected on the base frame 1; a protective frame 11, fixedly connected to the base frame 1, with an operation display assembly 8 on the top of the protective frame 11 for controlling the feeding assembly 2, the clamping and conveying assembly 4, the heating assembly 3, the pushing assembly 5, the discharging and waiting assembly 6, and the material box placement assembly 7. The operation display assembly 8 includes an operation display screen 81 fixedly connected to the top of the base frame 1. The operation display screen 81 is typically the user interface of the baking device, designed to control and monitor the baking process. The upper surface of the operation display screen 81 is equipped with a manually controlled tri-color LED buzzer 82, which emits an audible signal to alert the operator to the equipment status. The operation display screen 81 also includes an emergency stop switch 83.

[0039] Furthermore, the feeding assembly 2 includes a pair of separate conveyor line supports 22 fixedly connected to the base frame 1. The separate conveyor line supports 22 are structural components used to support and fix the conveyor line in the baking equipment. Their main function is to transport the chips or other products to be baked from one station to another in a certain rhythm and sequence. A motor support 21 corresponding to one of the separate conveyor line supports 22 is fixedly connected to the upper surface of the base frame 1. A drive motor 23 is fixedly connected to the top of the motor support 21, and a coupling 26 is fixedly connected to the output shaft of the drive motor 23. The coupling 26 is a mechanical component that connects different parts inside the equipment and transmits power or rotational motion. The separate conveyor line supports 22 are equipped with toothed synchronous pulley sets 24. Toothed synchronous pulley sets 24 are typically used to realize mechanical transmission within the equipment. The toothed synchronous pulley set 24 consists of a synchronous belt (usually a toothed belt) and matching synchronous pulleys. The teeth mesh with the teeth on the pulleys, thereby ensuring precise transmission. The top of the split conveyor support 22 is also equipped with a pair of baffle mechanisms 25. The baffle mechanisms 25 are mainly used to prevent chips or other materials from sliding, tilting or falling during the baking process, and to ensure that the baking materials are stably placed in the heating area. The end of the coupling 26 away from the drive motor 23 is connected to the toothed synchronous pulley set 24.

[0040] The clamping and conveying assembly 4 includes a support main plate 41 fixedly connected to the upper surface of the base frame 1. A lead screw moving mechanism 42 is provided on the upper surface of the support main plate 41. The lead screw moving mechanism 42 is typically a mechanical transmission system used in equipment, primarily for controlling the precise position or movement of the rotary cylinder connecting plate 43 on the baking equipment. A lead screw (also called a screw rod) is a commonly used component in mechanical transmission; it generates linear displacement through rotation. The rotary cylinder connecting plate 43 is slidably connected to the lead screw moving mechanism 42. A rotary cylinder 44 is provided on the lower surface of the end of the rotary cylinder connecting plate 43 away from the lead screw moving mechanism 42. The rotary cylinder 44 is a device that rotates via airflow, enabling the chip to uniformly contact the heat source during heating or processing, thereby avoiding localized overheating or underheating. A flexible gripper connecting plate 45 is fixedly connected to the bottom end of the rotary cylinder 44. A pair of SMC flexible grippers 46 are provided on the lower surface of the flexible gripper connecting plate 45. The SMC flexible grippers 46 are flexible gripper assemblies used to clamp and move the chip during the chip baking process. These grippers are typically made of SMC material, a composite material composed of resin and reinforcing fibers (such as glass fiber), which has high strength, high temperature resistance and good mechanical properties.

[0041] Secondly, the heating assembly 3 includes a support frame 31 fixedly connected to the upper surface of the base frame 1. The upper surface of the support frame 31 has multiple heating plate bases 35 arranged linearly. The heating plates 34 on the heating plate bases 35 are typically made of heat-resistant material. Each heating plate 34 has a heating plate 34 on its upper surface. A heating rod 36 and a temperature sensor 37 are located in the middle of each heating plate 34 and heating plate base 35. The heating rod 36 is typically an element that converts electrical energy into heat energy to heat the chip itself. The temperature sensor 37 typically uses a high-precision thermocouple to monitor the temperature. The temperature sensor 37 can provide accurate temperature data in high-temperature environments to ensure the temperature control accuracy of the equipment. Each heating plate 34 has a mold 32 on its upper surface. The mold 32 is typically used to support and fix the chip in the correct position during the baking process. Its design goal is to ensure uniform baking, prevent chip deformation, and effectively conduct heat. The mold 32 can be quickly replaced according to the size of the chip.

[0042] Furthermore, the feeding assembly 5 includes a pair of conveying brackets 51 fixedly connected to the upper surface of the base frame 1. The top of each conveying bracket 51 is equipped with a lead screw conveying module 52, which is a mechanical component used for precise conveying and positioning of chips during the baking process. Driven by a lead screw, it uses a rotating lead screw to move a nut or other connecting parts along a certain track, achieving automated conveying and positioning of chips or materials in the baking equipment. On both sides of the lead screw conveying module 52, the upper surface of the base frame 1 is equipped with a pair of baffle plate columns 53. The top of each baffle plate column 53 is fixedly connected to a G10 baffle plate 54. The G10 baffle plate 54 typically refers to a material or component used in a high-efficiency chip baking equipment. G10 is a common glass fiber reinforced plastic, usually composed of epoxy resin and glass fiber woven fabric. It has good mechanical strength, electrical insulation, and heat resistance, and is therefore often used in environments requiring high temperature resistance and electrical insulation. A push rod 56 is provided above one end of the lead screw conveyor module 52 near the conveyor bracket 51. The push rod 56 is a key component of the equipment and is usually used to push the chip or other product to be baked from one area to another.

[0043] Furthermore, the unloading waiting assembly 6 includes a horizontal axis moving module 61 fixedly connected to the upper surface of the base frame 1. The horizontal axis moving module 61 typically refers to a device used for the lateral horizontal movement of the chip during baking. This ensures precise control during the baking process, guaranteeing that the chip receives heat evenly. A vertical axis moving module 62 is horizontally slidably connected to the horizontal axis moving module 61. The vertical axis moving module 62 typically refers to a mechanical device used to control the vertical movement during the baking process. A gripping empty material box plate 63 is vertically slidably connected to the vertical axis moving module 62. The function of the gripping empty material box plate 63 is to grip and transport empty material boxes from a designated position to other parts of the device using a mechanical device. A material box 671 is also placed on the gripping empty material box plate 63. The material box 671 typically refers to a container used to place and carry the chip.

[0044] Furthermore, the material box placement assembly 7 includes a material box storage bracket 71 fixedly connected to the upper surface of the base frame 1. The material box storage bracket 71 is an assembly used to store and support material boxes used during the chip baking process. The material box storage bracket 71 is equipped with a pair of synchronous wheel brackets 72. A synchronous wheel conveyor belt assembly 75 is located at the top of the synchronous wheel brackets 72 and in the middle of the material box storage bracket 71. The synchronous wheel conveyor belt assembly 75 is typically a mechanical component used to transport chips or other electronic components through the heating zone of the baking equipment. This assembly generally consists of a conveyor belt, synchronous wheels, and a drive system, and its main function is to ensure stable and uniform movement of materials during the baking process. A stepper motor 73 driving the synchronous wheel conveyor belt assembly 75 is fixedly connected to the upper surface of the material box storage bracket 71. The stepper motor 73 is mainly used to precisely control the position, speed, and angle of various moving parts in the equipment, thereby ensuring that moving parts in the equipment (such as conveyor belts) move to the required positions. The material box storage bracket 71 is equipped with a pair of normally open proximity switches 74 corresponding to each other. The normally open proximity switches 74 are typically used to detect the presence or position of objects. When no object is near, its output is off (the switch is in the "normally open" state); when an object approaches, the switch closes, the output signal is activated, and subsequent control operations are triggered. Multiple rows of corresponding material boxes 671 are placed on the material box storage bracket 71.

[0045] In this embodiment, when a high-efficiency chip baking device is required, the chip first arrives at the feeding assembly 2. The drive motor 23 on the motor bracket 21 drives the toothed synchronous pulley set 24 through the coupling 26. When the coupling 26 rotates a certain angle or number of turns, the blocking mechanism 25 can lift or lower the chip through the transmission of the toothed synchronous pulley set 24, and smoothly transport the chip to the next process. When the chip arrives at the clamping and conveying assembly 4, it first sits on the support main board 41. The support main board 41 provides a stable placement platform for the chip. Then, the rotary cylinder connecting plate 43 can slide vertically on the lead screw moving mechanism 42, and the rotary cylinder 44 at the bottom of one end of the rotary cylinder connecting plate 43 drives the flexible gripper connecting plate 45. After that, the flexible gripper connecting plate 45 clamps the chip through the SMC flexible gripper 46 and transfers it to the next process. When the chip is transported to the heating assembly 3, it is first placed onto the mold 32 one by one. Furthermore, the shape and size of the mold 32 are closely matched to the chip, and then the laser beam detection device 33 is used to detect whether the chip is accurately placed in the mold 32. Then, the heating rod 36 operates to generate heat, which is transferred to the heating plate 34 and the mold 32 through heat conduction, thereby baking the chip. Further, when the baked chip is conveyed to the pusher assembly 5, the lead screw conveyor module 52 is responsible for the precise delivery of the chip, the G10 baffle plate 54 is used to prevent the chip from moving excessively, and the laser beam sensor 55 is used to detect the position and status of the chip. When the chip is in the correct position and the laser beam sensor 55 confirms that there is no problem, the pusher rod 56 moves forward, pushing the chip out of the pusher assembly 5 and conveying it to the unloading waiting assembly 6. Furthermore, the horizontal axis movement module 61 can move the vertical axis movement module 62 and the empty material box gripping plate 63 to directly above the chip or to a suitable horizontal position for subsequent gripping or other operations. The vertical axis movement module 62 and the horizontal axis movement module 61 work together, and the empty material box gripping plate 63 places the material box 671 onto the material box placement assembly 7. Finally, the stepper motor 73 provides power to the synchronous wheel conveyor belt assembly 75, thereby driving the material box 671 to move between the material discharge waiting assembly 6 and the material box placement assembly 7. The normally open proximity switch 74 is used to detect the position of the material box 671. When the material box 671 approaches or reaches a specific position, the normally open proximity switch 74 senses it and changes its output state from normally open to closed, sending a signal to the control system. Finally, the material box 671 is placed on the synchronous wheel conveyor belt assembly 75 to complete the entire conveying and placement process.
