[0039] Furthermore, the feeding module 2 includes a pair of split conveyor line brackets 22 fixedly connected to the base 1. The split conveyor line brackets 22 are structural components in the baking device for supporting and fixing the conveyor line. Its main function is to convey the chips or other products to be baked from one station to another at a certain rhythm and order. A motor bracket 21 corresponding to one of the split conveyor line brackets 22 is fixedly connected to the upper surface of the base 1. A driving motor 23 is fixedly connected to the top of the motor bracket 21. The output shaft of the driving motor 23 is fixedly connected to a coupling 26. The coupling 26 is a mechanical component for connecting different parts inside the device and transmitting power or rotational motion. A toothed synchronous pulley set 24 is provided on the split conveyor line brackets 22. The toothed synchronous pulley set 24 is usually a system for realizing mechanical transmission inside the device. The toothed synchronous pulley set 24 consists of a synchronous belt (usually a belt with teeth) and a matching synchronous pulley. The teeth mesh with the teeth on the pulley to ensure precise transmission. A pair of material blocking mechanisms 25 are also provided at the top of the split conveyor line brackets 22. The material blocking mechanisms 25 are mainly used to prevent the chips or other materials from sliding, tilting, or falling during the baking process, and ensure that the baking materials are stably placed in the heating area. One end of the coupling 26 away from the driving motor 23 is connected to the toothed synchronous pulley set 24.

[0040] Among them, the material clamping and conveying module 4 includes a support main board 41 fixedly connected to the upper surface of the base 1. A lead screw moving mechanism 42 is provided on the upper surface of the support main board 41. The lead screw moving mechanism 42 generally refers to a mechanical transmission system used in equipment, mainly used to control the precise position or movement of the rotating cylinder connecting plate 43 on the baking equipment. The lead screw (also called the screw rod) is a commonly used component in mechanical transmission, and it generates linear displacement through rotation. A rotating cylinder connecting plate 43 is slidably connected to the lead screw moving mechanism 42. A rotating cylinder 44 is provided on the lower surface of the end of the rotating cylinder connecting plate 43 away from the lead screw moving mechanism 42. The rotating cylinder 44 is a device that rotates through air flow and can enable the chip to evenly contact the heat source during the heating or processing process, thereby avoiding local overheating or unheated situations. The bottom end of the rotating cylinder 44 is fixedly connected to a flexible jaw connecting plate 45. A pair of SMC flexible jaws 46 are provided on the lower surface of the flexible jaw connecting plate 45. The SMC flexible jaws 46 refer to the flexible jaw assembly used to clamp and move the chip during the chip baking process. These jaws are usually made of SMC material. SMC is a composite material composed of resin and reinforcing fibers (such as glass fibers), with high strength, high temperature resistance, and good mechanical properties.

[0041] Secondly, the heating module 3 includes a support base 31 fixedly connected to the upper surface of the base 1. A plurality of heating plate bases 35 arranged linearly are provided on the upper surface of the support base 31. The heating plate bases 35 and the heating plates 34 are usually made of heat-resistant materials. Heating plates 34 are provided on the upper surfaces of the heating plate bases 35. Heating rods 36 and temperature sensors 37 are provided in the middle of the heating plates 34 and the heating plate bases 35. The heating rod 36 is usually an element that converts electrical energy into heat energy and is used to heat the chip itself. The temperature sensor 37 usually uses a high-precision thermocouple to monitor the temperature. And the temperature sensor 37 can provide accurate temperature data in a high-temperature environment to ensure the temperature control accuracy of the equipment. Molds 32 are provided on the upper surfaces of the heating plates 34. The molds 32 are usually tools used to support and fix the chip in the correct position during baking. Its design goal is to ensure uniform baking, avoid chip deformation, and effectively conduct heat, and the molds 32 can be quickly replaced according to the size of the chip.

[0042] Furthermore, the chip pushing module 5 includes a pair of conveying brackets 51 fixedly connected to the upper surface of the base 1. At the top of the conveying brackets 51, there is a screw conveyor module 52, which is a mechanical component used for precise conveying and positioning of chips during baking. It adopts a screw drive method, using a rotating screw to move a nut or other connecting parts along a certain track to achieve automatic conveying and positioning of chips or materials in the baking equipment. On both sides of the screw conveyor module 52 on the upper surface of the base 1, there is a pair of baffle columns 53. At the top of the baffle columns 53, there is a G10 baffle 54 fixedly connected. The G10 baffle 54 usually refers to a material or component used in a chip rapid baking equipment. G10 is a common fiberglass-reinforced plastic, usually composed of epoxy resin and fiberglass woven fabric, with good mechanical strength, electrical insulation and heat resistance, so it is often used in environments that require high temperature resistance and electrical insulation. Above one end of the screw conveyor module 52 close to the conveying bracket 51, there is a pusher rod 56, which is a key component in the equipment and is usually used to push the chips or other products to be baked from one area to another area.

[0043] Furthermore, the discharging waiting module 6 includes a horizontal axis moving module 61 fixedly connected to the upper surface of the base 1. The horizontal axis moving module 61 usually refers to a component in the equipment used to carry out horizontal movement of the chip baking. It ensures precise control during baking to ensure that the chips can be evenly heated during baking. Horizontally slidably connected to the horizontal axis moving module 61 is a vertical axis moving module 62. The vertical axis moving module 62 usually refers to a mechanical device in this kind of equipment used to control the vertical movement during baking. Vertically slidably connected to the vertical axis moving module 62 is a grasping empty cassette board 63. The function of the grasping empty cassette board 63 is to grasp and transport the empty cassette from a designated position to other parts of the equipment through a mechanical device. On the grasping empty cassette board 63, there is also placed a cassette 671, which usually refers to a container used to place and carry chips.

[0044] Furthermore, the cassette placement module 7 includes a cassette storage bracket 71 fixedly connected to the upper surface of the base 1. The cassette storage bracket 71 is a component for storing and supporting the cassettes used during the chip baking process. A pair of synchronous wheel brackets 72 are provided on the cassette storage bracket 71. At the top of the synchronous wheel bracket 72 and in the middle of the cassette storage bracket 71, there is a synchronous wheel conveyor belt assembly 75. The synchronous wheel conveyor belt assembly 75 is generally a mechanical component for conveying chips or other electronic components through the heating area of the baking equipment. This assembly is generally composed of a conveyor belt, synchronous wheels, and a drive system, and its main function is to ensure the stable and uniform movement of the materials during the baking process. A stepping motor 73 for driving the synchronous wheel conveyor belt assembly 75 is fixedly connected to the upper surface of the cassette storage bracket 71. The stepping motor 73 is mainly used to precisely control the position, speed, and angle of each moving part in the equipment, so as to ensure that the moving parts (such as the conveyor belt, etc.) in the equipment move to the required positions. A pair of normally open proximity switches 74 corresponding up and down are provided on the cassette storage bracket 71. The normally open proximity switches 74 are generally used to detect the presence or position of an object. When there is no object approaching, its output is disconnected (the switch is in the "normally open" state); when an object approaches, the switch closes, and the output signal is activated, triggering subsequent control operations. And multiple rows of cassettes 671 corresponding up and down are placed on the cassette storage bracket 71.

[0045] In this embodiment, when the chip fast baking equipment is needed, the chip first arrives at the feeding module 2, and the driving motor 23 on the motor bracket 21 drives the toothed synchronous wheel set 24 to run through the coupling 26. When the coupling 26 rotates a certain angle or number of turns, the blocking mechanism 25 can realize the action of lifting or lowering through the transmission of the toothed synchronous wheel set 24, and the chip is smoothly transported to the next process. When the chip arrives at the clamping and conveying module 4, it will first be located on the supporting main board 41. The supporting main board 41 provides a stable placement platform for the chip. Then the rotating cylinder connecting plate 43 can be adjusted vertically on the screw moving mechanism 42, and the rotating cylinder 44 at the bottom of one end of the rotating cylinder connecting plate 43 drives the flexible clamping claw connecting plate 45 to run, and then the flexible clamping claw connecting plate 45 clamps the chip through the SMC flexible clamping claw 46 and transfers it to the next process. When the chip is transported to the heating module 3, it will first be placed on the mold 32 one by one. The shape and size of the mold 32 closely match 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 generates heat and is transferred to the heating plate 34 and the mold 32 in turn through heat conduction, thereby baking the chip. Further, when the baked chip is transported to the push module 5, the screw conveying module 52 is responsible for the precise conveying 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 it is correct, the push rod 56 will move forward, push the chip out of the push module 5 and transport it to the discharge waiting module 6. Furthermore, the horizontal axis moving module 61 can move the vertical axis moving module 62 and the empty material box grabbing plate 63 to the top of the chip or a suitable horizontal position for subsequent grabbing or other operations. The vertical axis moving module 62 and the horizontal axis moving module 61 work together to grab the empty material box plate 63 and place the material box 671 on the material box placement module 7. Finally, after the stepper motor 73 runs, it provides power to the synchronous wheel conveyor belt assembly 75, thereby driving the material box 671 to move between the material discharge waiting module 6 and the material box placement module 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 and changes its output state from the normally open state to the closed state, and sends 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.
