Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a program burning device. Background Technology

[0002] During the manufacturing process, circuit boards with chips need to undergo a program burning operation, which involves embedding the program into the chip so that the chip can run independently without external memory and achieve some simple automatic control.

[0003] Currently, commercially available programming devices, such as the programming fixture and device disclosed in patent CN112286536A, typically have multiple sets of first programming probes mounted on a base, with a carrier plate elastically supported on the base. The carrier plate has multiple first programming stations, which support the board to be programmed, on which a first chip corresponding to a first programming station is mounted. A pressure plate is positioned above the carrier plate, with multiple first and second pressure posts connected to it. The first pressure posts rigidly press against the carrier plate, holding it against the base, while the second pressure posts elastically press against the board to be programmed, holding it against the carrier plate. The displacement of the carrier plate relative to the base and the elastic deformation of the second pressure posts are configured such that each set of first programming probes mates with the first chip to be programmed at the first programming station. Furthermore, this programming fixture can be electrically connected to or disconnected from the programmer, facilitating replacement of the programmer or the programming fixture. Therefore, existing programming devices can support the board to be programmed via a carrier plate, with a pressure plate positioned above the carrier plate. During use, the pressure plate moves downwards, causing the first pressure post on the pressure plate to press against the carrier plate, and the second pressure post to press against the board to be programmed on the carrier plate. This allows the first programming probe on the base to contact the first chip to be programmed on the board, and the programmer then programs the chip into the first chip, thus fulfilling the programming requirements. While this structure achieves the programming requirement, the first programming probe is typically fixedly mounted on a frame within the base. This fixed position of the probe makes it difficult to adjust as needed, resulting in poor flexibility. Consequently, when programming circuit boards with different chip positions, a new frame needs to be designed to accommodate the first programming probe, increasing equipment and manufacturing costs. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the present invention aims to provide a program programming device, wherein a plurality of parallel and spaced slide bars are provided on the base plate of the base, and the middle slide bar has a first slide groove on both sides along its own arrangement direction. The two outermost slide bars have a second slide groove on the side closer to the middle slide bar, and a sliding plate is provided between adjacent slide bars. The programming probe is mounted on the sliding plate, so that the position of the programming probe can be adjusted when the sliding plate slides on the slide bar. The structure is more flexible and adaptable to the programming needs of circuit boards with different chip positions.

[0005] The specific technical solution is as follows:

[0006] A programming device includes a base, a carrier plate, a pressure plate, and a clamping device. The carrier plate is mounted above the base, and a plurality of programming probes are mounted on the base. The carrier plate has programming holes corresponding to the programming probes one by one. A plurality of placement slots are provided on the top surface of the carrier plate, and the circuit board to be programmed is placed in the corresponding placement slot. The pressure plate is located above the carrier plate, and the clamping device is mounted on the base and connected to the pressure plate. The device also includes a plurality of sliders and a sliding plate. The sliders are all disposed in the base and arranged parallel to each other at intervals. Each slider in the middle region has a first groove arranged in the same direction on both sides. At the same time, the two outermost sliders, and the sliders closer to the middle region, each have a second groove arranged in the same direction on one side. A sliding plate is provided between each pair of adjacent sliders. The two ends of the sliding plate slide in the two first grooves of the two adjacent sliders or slide in the first grooves and second grooves of the two adjacent sliders, respectively. The programming probes are mounted on the sliding plate.

[0007] In the aforementioned program burning device, each of the first and second slide grooves is provided with a pressure bar, which presses against the top surface of the end of the corresponding slide. Each slide bar is provided with a quick-lock assembly that cooperates with the corresponding slide bar. The quick-lock assembly pushes the corresponding pressure bar downward or releases the corresponding pressure bar.

[0008] In the aforementioned program burning device, the quick-lock assembly includes an adjusting threaded hole, a threaded adjusting member, and a handle. The adjusting threaded hole is disposed on the slide bar and extends through to the corresponding first slide groove or second slide groove. The threaded adjusting member is installed in the adjusting threaded hole and one end extends into the corresponding first slide groove or second slide groove and presses against the corresponding pressure bar. The end of each threaded adjusting member facing away from the pressure bar is exposed outside the slide bar and is equipped with a handle.

[0009] In the aforementioned program burning device, one end of the threaded adjustment member with a handle has a slot opened radially thereon, and one end of the handle extends into the slot and is hinged to the slot.

[0010] In the aforementioned program burning device, each slider has an insertion port at both ends, and each insertion port corresponds to a pressure block. One end of the pressure block extends into the corresponding insertion port, and the other end of the pressure block has a mounting hole in which a locking screw connected to the base plate of the base is installed.

[0011] In the aforementioned program burning device, the slide plate is a rectangular plate, and the end faces of both ends of the slide plate are attached to the groove walls corresponding to the first or second slide groove.

[0012] In the aforementioned program burning device, each pressure bar has a rubber pad of the same length on the side that presses against the slide plate.

[0013] In the aforementioned program burning device, a plurality of clamping feet are mounted on the bottom surface of the pressure plate. The clamping feet are all arranged vertically downwards, and when the pressure plate moves down to clamp, the clamping feet clamp the circuit board to be processed on the carrier plate.

[0014] In the aforementioned program burning device, both the pressure plate and the clamping foot are made of transparent material.

[0015] In the aforementioned program burning device, a slide rod arranged vertically is provided on the base and located at one side edge, and a sliding sleeve is fitted on the slide rod and mounted on the pressure plate.

[0016] The positive effects of the above technical solution are:

[0017] The aforementioned programming device features several parallel sliding bars arranged at intervals in the base. First grooves, arranged in the same direction, are formed on both sides of the sliding bars in the middle region. Second grooves, arranged in the same direction, are formed on the two outermost sliding bars, one side of the sliding bar closest to the middle region. A sliding plate is positioned between adjacent sliding bars, with both ends extending into the two first grooves or into one first groove and one second groove. Programming probes are mounted on the sliding plate, allowing adjustment of the probe position by sliding the sliding plate along the sliding bars. This structure is more flexible, adapting to programming requirements of circuit boards with different chip locations, eliminating the need for a redesigned base and reducing manufacturing costs.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0023] Figure 1 This is a structural diagram of an embodiment of a program burning device according to the present invention. Figure 1 As shown, the programming device provided in this embodiment includes: a base 1, a carrier board 2, a pressure plate 3, and a clamping device 4. During assembly, the carrier board 2 is mounted on top of the base 1, and the mounting method of the carrier board 2 on the base 1 is consistent with the mounting method of the carrier board 2 in existing programming devices. Furthermore, a plurality of programming probes are mounted on the base 1, and programming holes 21 corresponding to the programming probes are formed on the carrier board 2, allowing the programming probes to contact the chips of the circuit board to be programmed placed on the carrier board 2 through the programming holes 21. In addition, a plurality of placement slots 22 are provided on the top surface of the carrier board 2, and the circuit board to be programmed is placed in the corresponding placement slot 22, providing accurate accommodating space for the circuit board to be programmed. In addition, the pressure plate 3 is placed above the carrier plate 2, and the clamping device 4 is installed on the base 1 and connected to the pressure plate 3. The clamping device 4 controls the pressure plate 3 to move down below the carrier plate 2 and press the circuit board to be burned on the carrier plate 2 to meet the burning requirements.

[0024] Figure 2 This is a structural diagram of the base after it has been opened according to a preferred embodiment of the present invention; Figure 3 This is a cross-sectional view of the slider and slide plate after installation according to a preferred embodiment of the present invention. Figures 1 to 3As shown, the base plate of the base 1 is also provided with several sliders 11 and a sliding plate 12. The sliders 11 are arranged parallel to each other at intervals, ensuring that each slider 11 is arranged in the same direction, thus providing conditions for the subsequent installation and smooth sliding of the sliding plate 12. Furthermore, each slider 11 in the middle area has a first groove 111 arranged in the same direction on both sides, ensuring that each slider 11 in the middle area has a corresponding first groove 111 on both sides to cooperate with the sliders 11 on either side, improving the utilization rate of the sliders 11 in the middle area and reducing space occupation. Simultaneously, the two outermost sliders 11, located closer to the middle area, each have a second groove 112 arranged in the same direction on one side, ensuring that the outermost slider 11 only has the second groove 112 on the side adjacent to other sliders 11. This provides conditions for the subsequent installation of the sliding plate 12 in conjunction with other sliders 11, and also prevents the sliding plate 12 from detaching from the second groove 112, improving structural reliability. In addition, a sliding plate 12 is provided between each pair of adjacent slide bars 11. When the sliding plate 12 is located between the two slide bars 11 in the middle region, both ends of the sliding plate 12 slide into the two first slide grooves 111 of the two adjacent slide bars 11, thus enabling the sliding plate 12 to be installed on the slide bars 11. When the sliding plate 12 is located between the outermost slide bar 11 and the middle slide bar 11, both ends of the sliding plate 12 slide into the first slide groove 111 and the second slide groove 112 of the two adjacent slide bars 11, thus also enabling the sliding plate 12 to be installed on the slide bars 11. Furthermore, the programming probe is mounted on the sliding plate 12, that is, the position of the programming probe is changed by sliding the sliding plate 12 on the slide bar 11, thereby adjusting the position of the programming probe, improving the structural flexibility, and thus adapting to the programming requirements of circuit boards with different chip positions, without the need to redesign the base 1, reducing the processing cost.

[0025] More specifically, each of the first slide grooves 111 and second slide grooves 112 is provided with a pressure strip 13. The pressure strip 13 is installed along the arrangement direction of the corresponding first slide groove 111 or second slide groove 112, allowing it to cover the length range of the corresponding first slide groove 111 or second slide groove 112. This ensures that the slider can be pressed and limited when it slides to any position within the first slide groove 111 or second slide groove 112. Furthermore, the pressure strip 13 is pressed against the top surface of the end of the corresponding slide plate 12, allowing direct contact and providing a condition for limiting the movement of the slide plate 12. Additionally, each slide bar 11 is provided with a quick-lock assembly 14 that cooperates with it. In use, the quick-lock assembly 14 pushes the corresponding pressure strip 13 downwards to press the slider or releases the corresponding pressure strip 13 upwards, allowing the slider to move relative to the slide bar 11. This meets the requirements for quick locking and unlocking, improving adjustment efficiency and making it more convenient to use.

[0026] More specifically, the quick-lock assembly 14 for quickly locking and releasing the pressure bar 13 includes an adjusting threaded hole 141, a threaded adjusting member 142, and a handle 143. The adjusting threaded hole 141 is disposed on the slide bar 11 and arranged vertically, extending through the top surface of the slide bar 11 into the corresponding first slide groove 111 or second slide groove 112. Simultaneously, a threaded adjusting member 142 is installed in the adjusting threaded hole 141, with one end extending into the corresponding first slide groove 111 or second slide groove 112. This allows the length of the threaded adjusting member 142 extending into the corresponding first slide groove 111 or second slide groove 112 to be adjustable when the threaded adjusting member 142 is turned. Furthermore, the end of the threaded adjusting member 142 extending into the corresponding first slide groove 111 or second slide groove 112 presses against the corresponding pressure bar 13, thereby pressing the pressure bar 13 down or releasing it upward. In addition, each threaded adjusting member 142 has its end facing away from the pressing strip 13 exposed outside the slide bar 11 and equipped with a handle 143, so that when adjustment is needed, the operator only needs to turn the threaded adjusting member 142 by using the handle 143, making the operation more convenient.

[0027] More specifically, a slot 1421 is radially formed on one end of the threaded adjusting member 142 where the handle 143 is mounted. The slot 1421 penetrates the end face and both side walls of the threaded adjusting member 142. At the same time, one end of the handle 143 extends into the slot 1421 and is hinged to the slot 1421. That is, a pin connects one end of the handle 143, which extends into the slot, to the slot 1421. This allows for mutual limiting in the circumferential direction of the threaded adjusting member 142, making it easy for the operator to quickly lock or unlock the threaded adjusting member 142 by turning the handle 143. If other structures inside the base 1 or the programming probe block the handle 143 from continuing to rotate after rotating a predetermined angle, the handle 143 can be flipped out of the slot 1421 to a symmetrical rotation state, allowing the operator to continue turning the threaded adjusting member 142, making the operation more convenient.

[0028] More specifically, each slider 11 has a slot 113 at its lower end. Each slot 113 corresponds to a pressure block 5. One end of the pressure block 5 is inserted into the corresponding slot 113, achieving a plug-in connection between the pressure block 5 and the slider 11, making disassembly and assembly more convenient. In addition, a mounting hole 51 is provided on the other end of the pressure block 5, and a locking screw connected to the base plate of the base 1 is installed in the mounting hole 51. This allows the pressure block 5 to be disassembled and installed on the base plate of the base 1 through the locking screw, thus facilitating the disassembly and assembly of each slider 11 on the base plate of the base 1, resulting in a more reasonable structural design.

[0029] More specifically, the slide plate 12 that slides between two adjacent slide bars 11 is a rectangular plate. When the slide plate 12 is installed on the two adjacent slide bars 11, the end faces of the two ends of the slide plate 12 are attached to the groove walls of the corresponding first slide groove 111 or second slide groove 112. Through the mutual contact between the end faces of the slide plate 12 and the groove walls of the corresponding first slide groove or second slide groove 112, surface contact in the sliding direction is achieved, which improves the stability of the slide plate 12 during sliding, prevents problems such as tilting of the slide plate 12, and ensures that the adjusted burning probe position can be more accurate.

[0030] More specifically, each pressure strip 13 has a rubber pad 131 of the same length on the side that presses against the slide plate 12. This allows the pressure strip 13 to press the corresponding end of the slide plate 12, and the rubber pad 131 further presses the slide plate 12. The slight deformation of the rubber pad 131 enhances the pressure on the slide plate 12, increasing friction, improving the pressing and limiting effect, and enhancing stability after locking. Preferably, the rubber pad 131 is bonded to the corresponding pressure strip 13, enabling quick installation of the rubber pad 131 on the corresponding pressure strip 13 and facilitating replacement in case of future damage, resulting in a more rational structural design.

[0031] More specifically, several clamping feet 31 are also installed on the bottom surface of the pressure plate 3. At this time, the clamping feet 31 are all arranged vertically downwards, forming several contact points at the bottom of the pressure plate 3. When the pressure plate 3 moves down to clamp, the clamping feet 31 clamp the circuit board to be processed on the carrier plate 2. That is, the circuit board to be processed is clamped by the clamping feet 31, so that when the pressure plate 3 clamps the circuit board, it is a multi-point distributed clamping, which makes it easy to avoid the electronic components on the circuit board. This can avoid the problem of completely covering and damaging other electronic components, while meeting the clamping requirements. The structural design is more reasonable.

[0032] More specifically, both the pressure plate 3 and the clamping foot 31 are made of transparent material. Preferably, both the pressure plate 3 and the clamping foot 31 are made of transparent acrylic material, which allows operators to observe the contact status between the clamping foot 31 and the circuit board in real time, preventing errors that could lead to misalignment of the clamping position and ensuring product quality.

[0033] More specifically, a vertically arranged slide rod 6 is provided on the base 1, located at one edge. The lower end of the slide rod 6 is fixed to the top plate of the base 1, and the upper end of the slide plate 12 is fixed to the stand on the base 1 for mounting the clamping device 4, thus achieving stable installation of the slide rod 6 on the base 1. Furthermore, a sliding sleeve 61 is fitted onto the slide rod 6 and installed on the pressure plate 3. The sliding of the sliding sleeve 61 on the slide rod 6 guides the lifting and lowering movement of the pressure plate 3, improving the stability of the pressure plate 3 during movement and ensuring that the clamping foot 31 accurately presses against the predetermined position on the circuit board to be processed. Preferably, the sliding sleeve 61 is a linear bearing, which not only meets the axial guidance requirements and improves the stability of the pressure plate 3 during vertical movement but also reduces wear and extends the service life of the device.

[0034] The programming device provided in this embodiment includes a base 1, a carrier board 2, a pressure plate 3, and a clamping device 4. Several parallel and spaced slide bars 11 are installed in the base 1. First grooves 111 arranged in the same direction are opened on both sides of the slide bar 11 in the middle region. A second groove 112 arranged in the same direction is opened on the side of the outermost slide bar 11 closest to the slide bar 11 in the middle region. A sliding plate 12 is provided between adjacent slide bars 11. The two ends of the sliding plate 12 slide in the corresponding two first grooves 111 or a corresponding first groove 111 and a second groove 112. The programming probe is installed on the sliding plate 12. The position of the programming probe is adjusted by sliding the sliding plate 12 on the slide bar 11, improving the flexibility of the structure and adapting to the programming requirements of circuit boards with different chip positions. This avoids the problem of needing to specifically design and replace the support for installing the programming probe, eliminating the need to reprocess the base 1, resulting in higher structural utilization, improved processing efficiency, and reduced processing costs.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
