Description

Technical Field

[0001] This invention relates to the field of PCB circuit board programming equipment technology, and specifically to a programming device. Background Technology

[0002] As the core component of various electronic devices, the programming process of chips is one of the key steps to ensure the normal operation of electronic devices. Especially in the production process of PCB circuit boards, the accurate and efficient programming of onboard chips directly affects the production efficiency and quality stability of products.

[0003] Currently, there are various devices and fixtures in the industry for programming chips on PCB circuit boards. Among them, Chinese utility model patent application number CN202120536555.3 discloses a chip programming fixture. This fixture has a positioning plate on the base for placing the circuit board chip. The upper side of the positioning plate has a movable platform that can move up and down. The movable platform is equipped with a connection terminal (i.e., a probe). The probe is connected to the programming device (i.e., a programmer). During operation, the movable platform moves downward so that the probe docks with the chip on the circuit board, and then the programmer completes the chip programming operation. This prior art has achieved a certain degree of automation in chip programming and provides a feasible technical solution for programming chips on PCB boards.

[0004] However, the aforementioned existing technologies still have the following problems in practical applications: On the one hand, the existing technology described above has a PCB board loading area and a working area on the right side of the base, while multiple programmers are arranged on the left side, forming a layout that separates the loading operation from the programming status monitoring. In actual production operations, the operator's focus is concentrated on the loading and working areas on the right side of the base, where core operations such as PCB board loading, positioning, and unloading must be completed. However, the programming status of the programmers needs to be checked on the left side of the base, which requires the operator to move frequently left and right during the operation. This not only increases the operator's workload but also reduces the continuity of operation and production efficiency, causing great inconvenience to actual production operations and making it difficult to adapt to the high-efficiency operation requirements of mass production scenarios.

[0005] On the other hand, in the aforementioned prior art, the probes are typically directly and fixedly connected to the moving platform. During the programming process, the moving platform moves the probe downwards, causing it to collide and make contact with the chip on the PCB circuit board to achieve electrical connection. Since chip programming requires long-term, high-frequency operation, the repeated collisions between the probe and the circuit board generate continuous impact force. This impact force continuously acts on the connection between the probe and the moving platform. Over time, this can easily lead to loosening of the connection between the probe and the moving platform, resulting in poor contact between the probe and the chip. This affects the stable transmission of programming signals, which can not only lead to programming failure and reduced product yield, but may also cause abnormal current due to poor contact, damaging the probe, chip, or PCB circuit board, increasing production and maintenance costs and material waste. Summary of the Invention

[0006] In view of the problems pointed out in the background art, the present invention proposes a programming device to solve the above-mentioned technical problems.

[0007] The technical solution of this invention is implemented as follows: A programming device includes a base, a feeding area on the upper side of the base, a pressure plate on the upper side of the feeding area, a probe assembly connected to the pressure plate, a bracket on the rear side of the base, and a drive device on the bracket for moving the pressure plate up and down. The support has vertically arranged display racks on its left and right sides, which are close to the support. Multiple programmers are arranged on the display racks along the vertical direction, and the number of programmers corresponds to the number of probe components. The programmer has two connectors that connect to the probe assembly and the power supply, respectively. The programmer is equipped with a programming status indicator light.

[0008] The present invention is further configured such that the probe assembly includes an elongated insulating substrate, one end of which is provided with a plurality of connecting grooves, and probes are connected in the connecting grooves; A linear conductive layer corresponding to the connection groove is provided on the insulating substrate along its length direction. One end of the conductive layer is electrically connected to the probe, and the other end of the conductive layer is connected to the programmer.

[0009] The present invention is further configured such that the pressure plate includes an upper plate and a lower plate that are spaced apart vertically, the lower plate has a fixing groove that is fixedly connected to an insulating substrate, the lower end of the insulating substrate extends to the lower side of the lower plate, and the upper end of the insulating substrate abuts against the lower side of the upper plate.

[0010] The present invention is further configured such that a connecting rod is provided between the upper plate and the lower plate to fix the two together.

[0011] The present invention is further configured such that a pressure rod corresponding to the probe assembly is provided on the lower side of the lower plate.

[0012] The present invention is further configured such that the front side of the display rack is provided with a mounting groove along the vertical direction, the programmer is adapted to be placed in the mounting groove, and the front side of the display rack is provided with a clamping strip along the vertical direction to fix the programmer.

[0013] The present invention is further configured such that the probe includes a fixing tube, a contact needle, and a spring; the fixing tube is closed at the top and is fixedly connected to the connecting groove; the spring is installed inside the fixing tube; and the upper end of the contact needle extends into the fixing tube and abuts against the spring.

[0014] The invention is further configured such that the lower end of the spring extends downward to form a linear insertion portion, and the upper end of the contact pin is provided with an insertion hole that is fixedly connected to the insertion portion.

[0015] The invention is further configured such that the spring includes a connecting section and a deformation section, the connecting section being able to form an interference fit with the inner wall of the fixed tube, and the outer diameter of the deformation section being less than or equal to the diameter of the inner wall of the fixed tube.

[0016] The present invention is further configured such that the driving device is a cylinder or a push-button handle that can swing up and down.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: The programming device provided by the present invention has display racks set vertically on the left and right sides of the rear side of the material feeding area of ​​the base, and the programmer connected to the probe assembly is installed on the display racks. This solves the problem that the operator needs to move left and right frequently during the operation.

[0018] During operation, while focusing on the material feeding area, staff can also keep an eye on the vertically arranged display racks on the left and right sides of the feeding area, and check whether the PCB circuit board program has been successfully burned by using the burning status indicator lights on the programmer.

[0019] This reduces the workload of staff and improves operational continuity and production efficiency.

[0020] The probe and insulating substrate can be pre-assembled into a probe assembly, and the insulating substrate is then fixedly connected to the pressure plate, compared to a structure in which the probe is directly fixedly connected to the pressure plate. The structure of this application does not require opening a large number of connection holes corresponding to the probes on the pressure plate (for example, if there are four probes on an insulating substrate, in a traditional structure, four corresponding connection holes need to be opened on the pressure plate). However, with the technical solution of this application, only one fixing hole corresponding to the insulating substrate needs to be opened, which simplifies the installation. In addition, the technical solution of this application directly fixes the probe to the insulating substrate, and the insulating substrate is then fixedly connected to the pressure plate. The connection strength between the probe and the pressure plate can be strengthened by the insulating substrate (the probe and the insulating substrate can form a larger contact and fixing area, and the insulating substrate and the pressure plate can also form a larger contact and fixing area), thus solving the problem that the connection between the probe and the pressure plate is easy to loosen.

Detailed Implementation

[0034] 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.

[0035] For reference as follows Figures 1-11 The present invention will be described as follows: Example: A programming device for programming chips on a PCB circuit board includes a base 1, which is a rectangular box structure to provide a stable mounting base for the various components of the device; the upper side plate of the base 1 is designed to be openable and closable, which facilitates the inspection and maintenance of the circuits and connecting components inside the base 1.

[0036] The upper side of the base 1 is provided with a material placement area 2, which is used to place the PCB circuit board to be programmed. To ensure that the circuit board does not shift during the programming process and to ensure the accuracy of the contact between the probe assembly and the chip, the material placement area 2 is designed with a groove structure that matches the contour of the circuit board to be programmed. The dimensions of this groove structure are precisely matched with the length, width and thickness of the circuit board, so that the circuit board can completely fit against the groove wall after placement, achieving stable positioning and avoiding the circuit board shifting due to the pressure of the pressure plate, probe contact and other operations, thereby ensuring the stability of the programming process.

[0037] The upper side of the feeding area 2 is equipped with a pressure plate that can move up and down. The pressure plate is the mounting carrier of the probe assembly. Its up and down movement can drive the probe assembly to contact or separate from the circuit board chip on the feeding area 2, providing structural support for starting and stopping the burning operation.

[0038] The pressure plate is fixedly connected with 12 probe components. This number setting enables simultaneous programming of 12 chips, improving the efficiency of the programming operation and adapting to the batch programming needs in mass production scenarios.

[0039] The base 1 has a support 3 on its rear side. The support 3 is made of rigid material and has sufficient structural strength. It is used to install the drive device 4 and the display rack 5.

[0040] The bracket 3 is equipped with a drive device 4 that drives the pressure plate to move up and down. The output end of the drive device 4 is fixedly connected to the pressure plate. Through the power output of the drive device 4, the pressure plate can be moved up and down precisely, thereby controlling the contact pressure and contact state between the probe assembly and the circuit board chip. The drive device 4 can be a cylinder or a push-button handle that can swing up and down. The specific selection can be determined according to the actual use scenario, cost requirements and operating habits. Its structure can refer to the drive mechanism disclosed in the prior art patent application number CN202120536555.3, which is a conventional technical means in this field and does not require additional modification. It can be directly adapted to the use requirements of this device.

[0041] Display racks 5 are vertically installed on the left and right sides of the bracket 3. The display racks 5 are close to the bracket 3 and have a plate-like structure. The display racks 5 are fixedly connected to the bracket 3 to ensure the installation stability of the display racks 5 and to prevent the display racks 5 from shifting due to equipment vibration during the burning process.

[0042] The function of the display rack 5 is to install the programmer 6. Each display rack 5 has 6 programmers 6 evenly arranged along the vertical direction. There are a total of 12 programmers 6 in the two display racks 5. The number of programmers 6 corresponds one-to-one with the 12 probe components on the pressure plate, ensuring that each probe component can establish an electrical connection with the corresponding programmer 6, so as to realize independent programming control of a single chip.

[0043] To ensure stable installation and easy disassembly of the programmer 6, a mounting groove 18 is provided on the upper side of the front side of the display rack 5 along the vertical direction. The size of the mounting groove 18 is adapted to the external size of the programmer 6, and the programmer 6 can be directly fitted and placed in the mounting groove 18 to achieve initial positioning.

[0044] Meanwhile, a clamping strip 19 for fixing the programmer 6 is provided on the front side of the display rack 5 along the vertical direction. The clamping strip 19 is made of transparent plastic sheet, and its upper and lower ends are fixed to the display rack 5 by bolts. Through the clamping action of the clamping strip 19, the programmer 6 is fixed in the mounting groove 18, preventing the programmer 6 from shifting. The clamping strip 19 is made of transparent material, which ensures that the operator can clearly observe the working status of the programmer 6 and the display of the programming status indicator 8 without disassembling the clamping strip 19, thus improving the convenience of operation.

[0045] The pressure plate is connected to 12 probe components, which can simultaneously program 12 chips. The number of programmers 6 on the two display racks 5 is set to correspond to the number of probe components.

[0046] The programmer 6 is the core functional component for programming the chip. The programmer 6 has two connectors 7 (connectors 7 are located at both ends of the programmer 6) that connect to the probe assembly and the power supply, respectively. One connector 7 connects to an external power source via a power cable to provide the programmer 6 with the necessary power. The other connector 7 connects to the probe assembly via a data cable, enabling signal transmission between the programmer 6 and the probe assembly, transmitting the programming program signal to the chip, and simultaneously providing feedback on the chip's programming status.

[0047] To facilitate real-time monitoring of the programming progress and status, the programmer 6 is equipped with a programming status indicator light 8. This indicator light includes three function lights: a normal power-on indicator light, a working indicator light, and a completed programming indicator light. The three lights use different colors (e.g., green for power-on, yellow for working, and red for completed). Operators can quickly determine the working status of the programmer 6 by observing the on / off state of these lights, eliminating the need for close inspection of the programmer 6's specific operating parameters and improving operational efficiency.

[0048] Programming device operation process: First, place the circuit board on the feeding area 2, then move the pressure plate downwards. The probe assembly on the pressure plate makes electrical contact with the chip on the corresponding circuit board. Then, turn on the control switch to power the programmer 6. The programmer 6 starts working and programs the chip on the circuit board.

[0049] In the above technical solution, the programmer 6 is mounted on a vertically arranged display rack 5, which is also positioned close to the left and right sides of the material feeding area 2. This allows workers to simultaneously monitor both the circuit boards on the material feeding area 2 and the programmer 6 on the display rack 5. This reduces the workload of workers and improves operational continuity and production efficiency.

[0050] The probe assembly is the component that enables the programmer 6 to make electrical connections with the chips on the PCB circuit board.

[0051] The probe assembly includes a long strip-shaped insulating substrate 9, which is made of insulating material (such as epoxy resin, polyimide, etc.). Its main function is to support the probe 11 and the conductive layer 12, and at the same time realize the insulation isolation between the probe 11 and the pressure plate, prevent short circuits between the probes 11, and ensure the stable transmission of the burning signal.

[0052] The insulating substrate 9 has four connecting slots 10 at one end and a terminal block 20 at the other end. The connecting slots 10 are arranged along the length of the insulating substrate 9, and the four connecting slots 10 are spaced apart in the width direction of the insulating substrate 9. The spacing between two adjacent connecting slots 10 is consistent to ensure that the installation position of the four probes 11 is accurate and can correspond one-to-one with the chip pins on the circuit board.

[0053] A probe 11 is fixedly connected inside the connecting groove 10. The upper end of the probe 11 abuts against the upper side wall of the connecting groove 10. This structural design can effectively prevent the probe 11 from moving upward during operation, ensuring the connection stability between the probe 11 and the connecting groove 10.

[0054] The other end of the insulating substrate 9 is connected to a terminal block 20, which is used to enable quick connection between the probe assembly and the data line.

[0055] An insulating substrate 9 has a linear conductive layer 12 extending along its length direction, corresponding to the connecting groove 10. The conductive layer 12 is made of conductive material (such as copper foil, silver paste, etc.), and its thickness is determined according to the conductivity requirements and the structural dimensions of the insulating substrate 9 to ensure good conductivity and structural stability.

[0056] One end of the conductive layer 12 extends into the connection groove 10 and is electrically connected to the probe 11 in the connection groove 10. The other end of the conductive layer 12 extends into the through hole at the other end of the insulating substrate 9 and is electrically connected to the pin of the terminal 20, thereby forming a signal transmission path of programmer 6 → data line → terminal 20 → conductive layer 12 → probe 11 → chip, ensuring that the programming signal can be transmitted stably and efficiently.

[0057] One end of the conductive layer 12 is electrically connected to the probe 11, and the other end of the conductive layer 12 is electrically connected to the terminal 20. The terminal 20 is electrically connected to the programmer 6 via a data cable. Both ends of the data cable are provided with connectors for insertion into the programmer 6 and the terminal 20, respectively.

[0058] The other end of the insulating substrate 9 is provided with four through holes, which correspond to four conductive layers 12 respectively, and the conductive layers 12 extend into the corresponding through holes. The terminal 20 has pins that are inserted into the four through holes (the pins are electrically connected to the corresponding conductive layers 12 after being inserted into the through holes).

[0059] Meanwhile, terminal block 20 is equipped with a connector for electrical connection to the data cable. One end of the data cable is plugged into connector 7 on the programmer 6, and the other end of the data cable is plugged into the connector on terminal block 20. This connection method enables electrical connection between the programmer 6 and the probe assembly. This structural design solves the problem in the prior art where probe 11 needs to be soldered separately to the data cable. It allows for quick connection and disconnection of the probe assembly and the programmer 6 without the need for professional soldering tools and operating skills, reducing installation and maintenance difficulty, and avoiding damage to probe 11 or data cable during the soldering process.

[0060] The pressure plate includes an upper plate 13 and a lower plate 14 spaced apart. Both the upper plate 13 and the lower plate 14 are made of rigid materials and have sufficient structural strength. They are fixedly connected by a connecting rod 16. The number of connecting rods 16 is determined according to the size of the pressure plate and the stress conditions to ensure that the upper plate 13 and the lower plate 14 are firmly connected and do not undergo relative displacement during the up and down movement.

[0061] It also includes a vertically arranged guide rod, and the rear side of the lower plate 14 is provided with a guide hole that slides with the guide rod.

[0062] The lower plate 14 is provided with a fixing groove 15 for fixing the insulating substrate 9. The fixing groove 15 is provided through the upper and lower sides of the lower plate 14. The insulating substrate 9 can be fixedly connected to the lower plate 14 with glue to ensure that the insulating substrate 9 is firmly connected to the pressure plate.

[0063] The lower end of the insulating substrate 9 extends to the lower side of the lower plate 14, allowing the probe 11 to extend out of the lower plate 14 and contact the circuit board chip on the feeding area 2; the upper end of the insulating substrate 9 abuts against the lower side of the upper plate 13. This structural design effectively disperses the reaction force experienced by the probe 11 during operation. When the probe 11 moves downward and contacts the circuit board, it experiences an upward reaction force, which is transmitted to the insulating substrate 9. Since the upper end of the insulating substrate 9 abuts against the upper plate 13, the upper plate 13 can apply a downward supporting force to the insulating substrate 9, preventing the insulating substrate 9 from moving upward. This avoids the fixed connection between the insulating substrate 9 and the lower plate 14 from loosening due to the upward force, ensuring the connection stability between the probe assembly and the pressure plate, and extending the service life of the equipment.

[0064] The lower side of the lower plate 14 is provided with a pressure rod 17 corresponding to the probe assembly. The pressure rod 17 is made of rigid material, and its length is determined according to the distance between the pressure plate and the feeding area 2. As the pressure plate moves downward and the probe 11 contacts the circuit board, the pressure rod 17 simultaneously contacts the upper side of the circuit board. As the pressure plate continues to move downward, the pressure rod 17 applies a downward clamping force to the circuit board, forming a clamping and fixing of the circuit board, preventing the circuit board from shifting during the programming process, ensuring the accurate contact between the probe 11 and the chip pins, and avoiding programming failure due to circuit board displacement.

[0065] The probe 11 includes a fixing tube 110, a contact needle 111, and a spring 112. The fixing tube 110, the contact needle 111, and the spring 112 are all made of copper.

[0066] The fixing tube 110 has a tubular structure with a closed upper end. The fixing tube 110 is fixedly connected to the connecting groove 10. The fixing tube 110 and the connecting groove 10 are fixedly connected by glue or interference fit to ensure that the fixing tube 110 does not shift during operation.

[0067] Spring 112 is installed inside fixed tube 110. Contact pin 111 is a cylindrical structure with its upper end extending into fixed tube 110 and abutting against spring 112. Contact pin 111 and fixed tube 110 are adapted and slidably connected, that is, contact pin 111 can slide up and down along the axis of fixed tube 110 to realize telescopic action.

[0068] During the programming process, when the pressure plate moves downward, the contact pin 111 first contacts the chip pin on the circuit board. As the pressure plate continues to move downward, the contact pin 111 is subjected to the reaction force of the circuit board, compressing the spring 112 upward until the pressure rod 17 on the pressure plate contacts and presses against the upper side of the circuit board. The pressure plate stops moving downward, and the spring 112 is in a compressed state, providing a continuous pressing force for the contact pin 111 to ensure stable electrical contact between the contact pin 111 and the chip pin. When the program is programmed, the drive device 4 drives the pressure plate to move upward, the reaction force on the contact pin 111 disappears, and under the elastic restoring force of the spring 112, it returns to its initial state, preparing for the next programming operation.

[0069] To achieve a reliable connection between the spring 112 and the contact pin 111, the lower end of the spring 112 extends downward to form a linear insertion part 113. The insertion part 113 is coaxially arranged with the spring 112. The upper end of the contact pin 111 has an insertion hole 114 that matches the insertion part 113. The insertion part 113 is inserted into the insertion hole 114. By interference fit or glue fixation, the spring 112 and the contact pin 111 are fixedly connected, ensuring that the elastic force of the spring 112 can be stably transmitted to the contact pin 111, while preventing the contact pin 111 from separating from the spring 112.

[0070] The spring 112 is divided into two parts: a connecting section 1121 and a deformation section 1122. The outer diameter of the connecting section 1121 is larger than that of the deformation section 1122. The upper end of the spring 112 is the connecting section 1121. The connecting section 1121 forms an interference fit with the inner wall of the fixed tube 110. Specifically, the outer diameter of the connecting section 1121 is slightly larger than the inner wall diameter of the fixed tube 110, so that the connecting section 1121 can fit tightly against the inner wall of the fixed tube 110, thereby achieving a fixed connection between the spring 112 and the fixed tube 110. The outer diameter of the deformation section 1122 is less than or equal to the inner wall diameter of the fixed tube 110, ensuring that the deformation section 1122 can freely expand and contract within the fixed tube 110, thereby achieving elastic deformation.

[0071] This structural design offers excellent maintainability. When the contact pin 111 or spring 112 is damaged (e.g., the contact pin 111 wears out or the spring 112 fails due to fatigue), the contact pin 111 and spring 112 can be disassembled and replaced. Because the contact pin 111 and spring 112 are lightweight, the interference fit between the connecting section 1121 and the fixing tube 110, the friction between the spring 112 and the fixing tube 110, and the friction between the contact pin 111 and the fixing tube 110 prevent the contact pin 111 and spring 112 from accidentally detaching from the lower end of the fixing tube 110. During disassembly, simply apply a downward pulling force to the contact pin 111 to pull the contact pin 111 and spring 112 out of the fixing tube 110, completing the disassembly and replacement. The operation is simple and convenient, eliminating the need to disassemble the entire probe assembly or pressure plate, thus reducing maintenance costs and time.

[0072] Alternatively, the contact pins 111 of the four probes on the probe assembly can be linked by setting a connecting rod. The lower end of the contact pin 111 is provided with a connecting hole that passes through both radial sides. The connecting rod passes through the connecting holes on the four contact pins 111, so that the four contact pins 111 can move up and down in a linked manner in the vertical direction, so that the contact pins 111 and the circuit board can maintain the same and stable contact state.

[0073] The working process of the programming device: Open the upper side panel of base 1 and check the connection status of each component. Ensure that the connection between programmer 6 and probe assembly and power supply is reliable, the programming status indicator 8 is working normally, the pressure plate moves smoothly, and the slot structure of the feeding area 2 is free of debris and damage. Place the PCB circuit board to be programmed into the slot structure of feeding area 2, ensuring that the circuit board is accurately positioned with the chip pins facing upwards and corresponding one-to-one with the positions of the probe assembly.

[0074] Start the drive device 4, which drives the pressure plate to move downwards, and the pressure plate drives the probe assembly to move downwards synchronously. During this process, the contact pin 111 of the probe 11 first contacts the chip pin on the circuit board. As the pressure plate continues to move downwards, the contact pin 111 is subjected to the reaction force of the circuit board, compressing the spring 112 upwards, until the pressure rod 17 on the lower plate 14 contacts and presses against the upper side of the circuit board. At this time, the pressure plate stops moving downwards, and the spring 112 is in a compressed state, providing a continuous clamping force for the contact pin 111, ensuring stable electrical contact between the contact pin 111 and the chip pin.

[0075] Turn on the control switch, and the external power supply powers the programmer 6 through the power cord. The programmer 6 is powered on normally, and the normal power-on indicator light on the programmer 6 will light up. The programmer 6 starts working, transmitting the preset program signal to the terminal 20 through the data line, then through the conductive layer 12 to the probe 11, and then through the contact pin 111 to the chip on the circuit board to begin program programming. At this time, the working indicator light on the programmer 6 will light up, and the operator can check the programming progress in real time through the programming status indicator light 8.

[0076] Once the chip program is successfully programmed, the program completion indicator light on programmer 6 illuminates, signaling to the operator that programming is complete. The drive unit 4 is then activated, causing the pressure plate to move upwards. The reaction force on contact pin 111 disappears, and it returns to its initial state under the elastic restoring force of spring 112, separating pressure rod 17 from the circuit board. The operator removes the programmed circuit board from the feeding area 2 and places the next batch of circuit boards to be programmed into it. This process is repeated to achieve batch programming.

[0077] By adopting the above technical solution, the beneficial effects of the present invention are as follows: This technical solution mounts the programmer 6 on a vertically arranged display rack 5, with the display rack 5 positioned near the left and right sides of the feeding area 2. This changes the existing layout where the feeding area and programmer are separated, allowing operators to focus their attention on the feeding area 2 while still maintaining control over the display rack 5 located near the feeding area 2. When loading and unloading circuit boards in the feeding area 2, operators do not need to move frequently left and right. They can quickly check the programming status indicator lights 8 on the programmer 6 on the display rack 5 to see the programming completion status of each chip. This effectively reduces the workload of operators, improves operational continuity, and thus increases the production efficiency of the programming operation, meeting the high-efficiency operation requirements of mass production scenarios.

[0078] In this technical solution, the probe 11 and the insulating substrate 9 can be pre-assembled into a complete probe assembly, and then the insulating substrate 9 is fixedly connected to the pressure plate. Compared with the structure in the prior art where the probe 11 is directly fixedly connected to the pressure plate, it has the following advantages: In the prior art, if one probe assembly corresponds to multiple probes 11, multiple connection holes corresponding to the number of probes 11 need to be opened on the pressure plate, which is cumbersome and difficult to position; In this technical solution, multiple probes 11 can be integrated on one insulating substrate 9 (4 in this solution), and only one fixing groove 15 corresponding to the insulating substrate 9 needs to be opened on the pressure plate to realize the synchronous installation of multiple probes 11, which simplifies the installation process, reduces the installation difficulty, and improves the installation efficiency. The probe 11 is directly fixedly connected to the insulating substrate 9, and the insulating substrate 9 is fixedly connected to the pressure plate. Compared with the probe 11 being directly connected to the pressure plate, the insulating substrate 9 can form a larger contact and fixing area with the probe 11. At the same time, the insulating substrate 9 and the pressure plate can also form a larger contact and fixing area, which effectively disperses the reaction force received by the probe 11 during operation, avoids the connection between the probe 11 and the pressure plate from loosening due to long-term stress, ensures the stability of the connection between the probe assembly and the pressure plate, reduces problems such as programming failure and chip damage caused by loose connection, improves the reliability of programming operation, and reduces production losses.

[0079] In this technical solution, the spring 112 of the probe 11 forms an interference fit with the fixed tube 110 through the connecting section 1121. The spring 112 and the contact needle 111 are fixedly connected through the insertion part 113 and the insertion hole 114. This structural design allows the contact needle 111 and the spring 112 to be disassembled and replaced separately. When the contact needle 111 is worn or deformed, or the spring 112 fails due to fatigue, the operator does not need to disassemble the entire probe assembly or pressure plate. Simply apply a downward pulling force to the contact needle 111 to remove the contact needle 111 and the spring 112 from the fixed tube 110 and replace them with new ones. The operation is simple and convenient, shortens maintenance time, reduces maintenance costs, and extends the service life of the entire device.

[0080] The slot structure in the feeding area 2 enables precise positioning of the circuit board, while the pressure rod 17 on the pressure plate clamps and fixes the circuit board, preventing displacement during the programming process. The spring structure of the probe 11 provides continuous clamping force to the contact pin 111, ensuring stable electrical contact between the contact pin 111 and the chip pins. The dual fixing structure of the insulating substrate 9 and the pressure plate ensures the installation stability of the probe assembly. The synergistic effect of the multiple positioning and clamping structures effectively avoids programming failures caused by poor contact or positioning deviations, improving the stability of the programming operation and the product yield.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
