Description

Technical Field

[0001] This utility model relates to the field of chip programming technology, and in particular to a small chip programming device. Background Technology

[0002] Chip programming (IC programming) refers to the process of writing or burning programs onto integrated circuits (ICs). This process is often called "programming" or "programming." Programming is the process of writing program code or data into an IC chip, enabling the chip to perform specific functions. In the production process, the control chip initially has no program and needs to be programmed using a programmer to write the written program into the chip so that it can perform operations according to the designed functions. This process is an indispensable part of electronic product manufacturing, ensuring the normal operation and functional realization of the microcontroller.

[0003] Patent application number 202021276391.7 discloses a multi-station chip programming device that solves the problem of large space occupation in existing multi-station chip programming devices. It includes a programming base and n sets of programmers. The programming base is cylindrical and rotatably mounted on a work platform via a rotary drive mechanism, with the rotation axis of the programming base perpendicular to the work platform. The n sets of programmers, where n ≥ 2, are evenly distributed along the circumference of the top plane of the cylindrical programming base. However, this device has the following problems: firstly, the programming base is difficult to disassemble when needed for replacement; secondly, programming failures due to misoperation cannot be avoided. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. This device features an iron ring at the bottom of each chip placement base, which magnetically attracts and connects to a magnetic strip on the inner wall of the placement slot. Simultaneously, the placement base snaps into the mounting through-hole for installation, facilitating future maintenance or replacement of placement bases of different specifications to accommodate various chip package types. A cylinder drives a pressure plate to press vertically downwards, causing eight pressure columns with silicone heads to contact the top center of the chip to be programmed and apply a certain force. This ensures that all chip pins can fully form a good electrical connection with the conductive contacts below, preventing poor pin contact due to bias voltage. This solves the technical problems of difficulty in disassembling the programming base during replacement and the inability to avoid programming failures caused by misoperation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A small chip programming device includes a base, an equipment box at the upper end of the base, a programming circuit board inside the equipment box, the programming circuit board being electrically connected to a control unit, a fixing plate at the center of the upper end of the equipment box, eight placement slots evenly formed at the upper end of the fixing plate, each placement slot containing a chip placement seat, and a pressure plate assembly at the rear of the upper end of the equipment box.

[0007] As a preferred embodiment, the lower end of the inner wall of the placement groove is provided with a placement seat mounting step, the upper end of the placement seat mounting step is provided with a magnetic strip, and the interior of the placement seat mounting step is provided with a mounting through hole.

[0008] As a preferred embodiment, the chip placement base includes a bottom placement base that can be fitted into the mounting through hole. The upper side of the placement base is provided with an iron ring that is adapted to the position and shape of the magnet strip for magnetic adsorption. The bottom of the chip placement base is provided with conductive contacts that are electrically connected to the programming circuit board.

[0009] As a preferred embodiment, the pressure plate assembly includes a gantry support frame. The lower ends of the gantry support frame are fixedly connected to the rear upper side of the equipment box on both sides. A cylinder is provided at the center of the upper end of the gantry support frame. A piston rod is movably connected inside the cylinder. A pressure plate is fixedly connected to the lower end of the piston rod. Eight pressure columns are evenly provided at the lower end of the pressure plate. A pressing column is provided at the center of the rear lower side of the pressure plate. Guide sleeves are provided at the center of the left and right sides of the pressure plate and at the left and right rear ends. The guide sleeves are slidably connected to the guide columns on their inner walls. The lower ends of the guide columns are fixedly connected to the upper end of the equipment box.

[0010] As a preferred embodiment, the eight pressure posts correspond to the center positions of the eight chip placement seats, and the lower end of each pressure post is fitted with a silicone head, and the lower end of the pressure post is flush with the lower end of the push post.

[0011] As another preferred embodiment, a power button is provided at the center of the upper end of the device box. The position of the power button corresponds to the position of the push button, and the power button is electrically connected to the control unit of the programming circuit board.

[0012] The beneficial effects of this utility model are:

[0013] (1) In this utility model, each chip placement base is provided with an iron ring at the lower end, which forms a magnetic adsorption connection with the magnet strip on the inner wall of the placement groove. At the same time, the placement base is inserted into the installation through hole to achieve installation, which ensures the stability of the chip placement base installation and facilitates later maintenance or replacement of placement bases of different specifications to adapt to chips of various packaging types.

[0014] (2) In this utility model, the cylinder drives the pressure plate to press down vertically, which drives the eight pressure columns with silicone heads to contact the top center of the chip to be programmed and apply a certain force to ensure that all chip pins can fully form a good electrical connection with the conductive contacts below, and prevent poor pin contact due to bias voltage.

[0015] (3) In this utility model, the structure of the push post provided on the back of the pressure plate and the power button on the device box are aligned. Only when the pressure plate is fully lowered and the push post is pressed against the center of the chip can the push post flush with the lower side trigger the power button, thereby sending a signal to the control unit to allow burning and start the burning program.

[0016] In summary, this device has the advantages of improving maintenance efficiency and adaptability, and ensuring reliable contact between the chip and the contacts, making it particularly suitable for the field of chip programming technology. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figures 1 to 6As shown, this utility model provides a small chip programming device, including a base 1, a device box 2 on the upper end of the base 1, and a door at the front end of the device box 2 for easy maintenance or debugging of electrical connections. The device box 2 contains a programming circuit board with a serial communication interface, which can download firmware programs to an external PC and distribute them to each programming channel through a control unit. The programming circuit board is electrically connected to the control unit, and the control unit distributes firmware programs to each channel through the programming circuit board. A fixing plate 21 is provided at the center of the upper end of the device box 2. The fixing plate 21 serves as a chip carrier mounting platform. Eight placement slots 211 are evenly distributed on the upper end of the fixing plate 21, and each placement slot 211 contains a chip placement seat 3. A pressure plate assembly 4 is provided on the rear side of the upper end of the device box 2.

[0027] Furthermore, a mounting step 212 is provided around the lower end of the inner wall of the placement groove 211. The mounting step 212 limits the installation depth of the chip placement base 3 to prevent the chip placement base 3 from sinking too deep and affecting the connection accuracy of the conductive contacts. A magnetic strip 213 is provided around the upper end of the mounting step 212. The mounting step 212 has a mounting through hole 214 inside. The mounting through hole 214 penetrates the bottom of the fixing plate 21 and is aligned with the programming circuit board. The diameter of the mounting through hole 214 is slightly larger than the outer diameter of the placement base 31 by 0.1mm, forming a sliding transition fit with the placement base 31, which allows for easy insertion and removal and also limits lateral swaying.

[0028] Furthermore, the chip placement base 3 includes a bottom placement base 31, which can be fitted into the mounting through hole 214. An iron ring 32, approximately 1mm thick, is provided on the upper side of the placement base 31 and is embedded in the outer shell of the chip placement base 3, with only the bottom surface exposed. The iron ring 32 is matched in position and shape to the magnetic strip 213 for magnetic attraction. The outer contour of the placement base 31 matches the mounting through hole 214. After the chip placement base 3 is inserted and installed in place through the mounting through hole 214... The iron ring 32 is firmly attracted to a fixed position by magnetic attraction. The magnetic connection is designed in a non-circuit area and does not affect the programming process. Each chip placement base 3 has a conductive contact 33 at its bottom. The conductive contact 33 is electrically connected to the programming circuit board. When it is necessary to replace or maintain the chip placement base 3, simply disconnect the conductive contact 33 from the programming circuit board, then use a small suction cup-like device to pick up the old chip placement base 3, pull the old chip placement base 3 upwards, and replace it with a new type of placement base for electrical connection.

[0029] Furthermore, the pressure plate assembly 4 includes a gantry support frame 41. The lower ends of the gantry support frame 41 are fixedly connected to the upper rear side of the equipment box 2. A cylinder 42 is provided at the center of the upper end of the gantry support frame 41. A piston rod 421 is movably connected inside the cylinder 42. The lower end of the piston rod 421 is fixedly connected to the pressure plate 43. The cylinder 42 drives the piston rod 421 to press down the pressure plate 43 by precisely controlling the output pressure through an external air circuit. Eight pressure columns 431 are evenly provided at the lower end of the pressure plate 43. A pressing column 432 is provided at the center of the rear side of the lower end of the pressure plate 43. Guide sleeves 44 are provided at the center of the left and right sides and the left and right ends of the rear side of the pressure plate 43. The guide sleeves 44 are lined with self-lubricating bearings to ensure that the pressure plate 43 descends smoothly and without jamming throughout the entire stroke. The inner walls of the guide sleeves 44 are slidably connected to guide columns 441. The lower ends of the guide columns 441 are fixedly connected to the upper end of the equipment box 2.

[0030] Furthermore, the eight pressure posts 431 correspond to the center positions of the eight chip placement seats 3, ensuring that pressure is directly transmitted to the chip body rather than the pins, preventing pin bending or breakage. The lower end of each pressure post 431 is fitted with a silicone head 4311, which has a certain degree of elasticity and can deform slightly under pressure, protecting the chip from damage. The lower ends of the pressure posts 431 and the push posts 432 are flush.

[0031] Furthermore, a power button 22 is provided at the center of the upper end of the device box 2. The position of the power button 22 corresponds to the position of the push post 432. The power button 22 is electrically connected to the control unit of the programming circuit board. Only when the pressure plate 43 has completed all the pressing actions and all the pressure posts 431 have reached the preset end position will the push post 432 just contact the power button 22. At this time, the button is pressed, generating a signal sent to the control unit. After the control unit detects this signal, it issues a command to start the programming process.

[0032] Working process: First, the operator places the chips to be programmed one by one on the chip placement seat 3. Then, the cylinder 42 is activated to drive the piston rod 421 to move down, causing the pressure plate 43 to descend vertically along the guide post 441. Next, the eight pressure posts 431 at the lower end of the pressure plate 43 simultaneously contact the center of the top of the chip. The silicone head 4311 applies uniform pressure to make the chip pins fit tightly with the conductive contact 33. At this time, the pressure plate 43 is fully pressed down. The push post 432 on the back of the pressure plate triggers the power button 22 on the device box 2. Then, the control unit detects the trigger signal and starts the programming circuit board. The programming program is sent to all chips in parallel through the conductive contact 33. Finally, after programming is completed, the cylinder 42 resets, the pressure plate 43 rises, and the operator takes out the programmed chip.

[0033] Secondly, when it is necessary to replace or maintain the chip holder 3, simply disconnect the electrical connection between the conductive contact 33 and the programming circuit board, then pull out the old chip holder 3 upwards and replace it with a new type of holder for electrical connection. This is convenient, quick, and easy to maintain.
