Description

Technical Field

[0001] This utility model relates to the field of hot presses, and in particular to a single-station hot press with pressure sensing. Background Technology

[0002] A hot press is a device that achieves electromechanical connection through heating and pressure. Its working principle is mainly based on pulse heating technology or electromagnetic heaters, combined with temperature sensors to achieve precise temperature control. There are various types of hot presses, including constant temperature hot presses, pulse hot presses, and vacuum hot presses, suitable for multiple industrial fields such as forging, stamping, and woodworking.

[0003] The pulse hot press applies a certain pulse voltage to the hot press head, which heats up the object to be connected to it. When the temperature reaches the solder melting point (i.e., the preset temperature), the solder between the objects to be connected melts and joins them together.

[0004] When soldering high-precision products (such as circuit boards), there are specific requirements for the pressure applied after the solder melts. However, the position of the pressure sensor in existing hot press soldering machines is generally fixed, and the pre-pressure stroke is not adjustable during actual hot pressing, as illustrated by the pulse hot press soldering machine disclosed in Chinese patent CN210967361U. Furthermore, the pre-pressure stroke requirements vary for different products during hot press soldering. This results in some existing pulse hot press soldering machines having a narrow application range, only capable of meeting the hot pressing requirements for soldering of a specific type of product. When soldering other products, the pressure may be too high or too low, affecting the soldering quality. Utility Model Content

[0005] The core of this invention lies in the fact that by setting up a pressure regulating unit, the pressure sensor can be made adjustable, thereby solving the problem of limited applicability caused by the fixed position of the pressure sensor in the prior art.

[0006] To solve the above problems, the present invention adopts the following technical solution.

A hot press unit is mounted at the front end of the vertical moving component and is located directly above the hot press platform. The winding unit includes a vertical plate fixedly connected to the base plate and a reel fixedly connected to the top of the vertical plate. A wire control component is fixedly connected to the rear end of the solder wire pulling mechanism. The working end of the solder wire pulling mechanism, the center of the wire control component, and the bottom of the reel are on the same horizontal plane. Solder wire is wound on the reel. The movable end of the solder wire passes through the wire control component and is clamped by the working end of the solder wire pulling mechanism. The hot pressing unit includes a U-shaped plate with its opening away from the vertical moving component, a front cover fixedly connected to the outside of the U-shaped plate, a guide rod that moves through the bottom of the U-shaped plate, a limiting block and a hot pressing head fixedly connected to the upper and lower ends of the guide rod, a guide rail installed on the vertical inner wall of the U-shaped plate, two sliders slidably connected on the guide rail, and the two sliders are fixedly connected to the pressure regulating unit and the limiting block, respectively.

[0009] Furthermore, the pressure regulating unit includes a positioning block fixedly connected to the upper slider, a pressure sensor fixedly connected to the lower end of the positioning block, a sleeve inserted into the upper end of the U-shaped plate, a threaded connecting pipe fixedly connected to the upper end of the positioning block, and a double-layer threaded cap sleeved on the outer side of the upper end of the sleeve. The lower end of the sleeve is connected to the bottom of the U-shaped plate by a semi-circular clamp. The threaded connecting pipe moves through the sleeve and extends into the double-layer threaded cap, and the double-layer threaded cap is threadedly connected to the threaded connecting pipe.

[0010] Furthermore, the two fine-tuning platforms are fixedly connected to each other. The fine-tuning platform includes a base, a movable platform slidably connected to the top of the base, two external protrusions fixedly installed on the outer ends of the base and the movable platform, and a cylinder installed on the external protrusion corresponding to the base. The extended end of the cylinder abuts against another external protrusion. The two cylinders on the two fine-tuning platforms are arranged horizontally and vertically, respectively.

Detailed Implementation

[0017] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0018] First implementation method: Figure 1 The diagram illustrates a single-station hot press with pressure sensing, where 'a' represents solder wire. It includes a base plate 11 and a hot press body 12 with a controller fixedly mounted on the upper part of the base plate 11. In practice, those skilled in the art can select a suitable controller model, such as a K-type 1400W, according to actual needs. A main display 2 is mounted on the top of the hot press body 12, primarily used to display various parameters of the hot press. From left to right, a solder wire pulling mechanism 5, two vertically stacked fine-tuning platforms 7, and a winding unit are fixedly mounted on the upper part of the base plate 11. A hot press platform 8 is fixedly connected to the upper end of the fine-tuning platform 7. The solder wire pulling mechanism 5, the fine-tuning platform 7, and the winding unit are all located in front of the hot press body 12. A vertical moving component 4 is mounted at the front end of the hot press body 12, and a hot press unit 3 is mounted at the front end of the vertical moving component 4. The hot press unit 3 is located directly above the hot press platform 8. Figure 2Two fine-tuning platforms 7 are fixedly connected to each other. The fine-tuning platform 7 includes a base 71, a movable platform 72 slidably connected to the top of the base 71, two external protrusions 701 fixedly installed on the outer ends of the base 71 and the movable platform 72, and a cylinder 73 installed on the external protrusion 701 corresponding to the base 71. In specific implementation, those skilled in the art can select a suitable model of cylinder 73 according to actual needs, such as CA1B32-50. The extended end of the cylinder 73 abuts against another external protrusion 701. The two cylinders 73 on the two fine-tuning platforms 7 are arranged horizontally and vertically, respectively. During hot pressing, the workpiece to be hot-pressed can be placed on the hot pressing platform 8. At the same time, through the mutual cooperation of the two fine-tuning platforms 7, the position of the workpiece can be finely adjusted in both the longitudinal and transverse directions.

[0019] The winding unit includes a vertical plate 61 fixedly connected to the base plate 11 and a spool 62 fixedly connected to the top of the vertical plate 61. Solder wire for welding is wound on the spool 62. A wire control assembly is fixedly connected to the rear end of the solder wire pulling mechanism 5. The working end of the solder wire pulling mechanism 5, the center of the wire control assembly, and the bottom of the spool 62 are on the same horizontal plane. Solder wire is wound on the spool 62. The movable end of the solder wire passes through the wire control assembly and is clamped by the working end of the solder wire pulling mechanism 5. During hot-press welding, the solder wire pulling mechanism 5 can clamp the solder wire at the end of the wire control assembly and squeeze it together with the workpiece when the hot-press unit 3 moves down. When the solder wire melts, it is welded together with the workpiece. After one welding is completed, the hot-press unit 3 moves up, and the working end of the solder wire pulling mechanism 5 can extend again to clamp the end of the wire control assembly that has broken due to melting and perform the next hot-press soldering. like Figures 3-4The hot pressing unit 3 includes a U-shaped plate with its opening away from the vertical moving component 4, a front cover 31 fixedly connected to the outside of the U-shaped plate, a guide rod 35 movably penetrating the bottom of the U-shaped plate, limiting blocks 34 fixedly connected to the upper and lower ends of the guide rod 35, and a hot pressing head 33. A guide rail 302 is installed on the vertical inner wall of the U-shaped plate, and two sliders are slidably connected to the guide rail 302. The two sliders are fixedly connected to the pressure adjusting unit 36 ​​and the limiting block 34, respectively. A pressure adjusting unit 36 ​​is provided on the upper part of the U-shaped plate. The vertical moving component 4 includes a hot pressing head 33. The press body 12 is fixedly connected to an outer casing 41, two end plates 42 respectively fixedly connected to the upper and lower ends of the outer casing 41, and a front cover plate 43 fixedly connected to the end of the two end plates 42 away from the hot press body 12. A motor 44 is fixedly installed at the lower end of the lower end plate 42. In specific implementation, those skilled in the art can select a suitable model of motor 44 according to actual needs, such as Panasonic MDMA152P1V. The output end of the motor 44 is connected to a lead screw 45 through a coupling. The upper end of the lead screw 45 is connected to the upper end plate 43 through a bearing. 2. Fixed connection: A nut 46 is threaded onto the lead screw 45, and a U-shaped connecting plate 401 is fixedly connected to the nut 46. A follower plate 402 is fixedly connected to the outer end of the U-shaped connecting plate 401. The follower plate 402 is fixedly connected to the hot pressing unit 3, and the front cover plate 43 moves through the space enclosed by the U-shaped connecting plate 401 and the follower plate 402. When it is necessary to control the hot pressing head 33 to move up and down for hot pressing welding, the motor 44 drives the lead screw 45 to rotate. Due to the restriction of the front cover plate 43 on the U-shaped connecting plate 401 and the follower plate 402, it forces... The U-shaped connecting plate 401 can only move up and down along the lead screw 45, thereby driving the hot pressing unit 3 to move up and down. During hot pressing, when the hot pressing head 33 moves down and comes into contact with the workpiece, its downward movement is restricted, which causes the guide rod 35 and the limiting block 34 to move up along the guide rail 302 until they come into contact with the pressure sensor 32, causing the pressure sensor 32 to generate data. This data can indicate the force on the workpiece, and the data can be displayed synchronously on the pressure display 301 to provide the operator with information on the force on the product during the hot pressing process.

[0020] It is worth noting that the controller, main display 2, and hot press head 33 are all existing structures in existing pulse hot presses and are not considered as technical points of this solution, so they will not be described in detail here.

[0021] like Figure 6The pressure regulating unit 36 ​​includes a positioning block 364 fixedly connected to the upper slider, a pressure sensor 32 fixedly connected to the lower end of the positioning block 364, a sleeve 362 inserted into the upper end of the U-shaped plate, a threaded connecting pipe 363 fixedly connected to the upper end of the positioning block 364, and a double-layer threaded cap 361 sleeved on the outer side of the upper end of the sleeve 362. The lower end of the sleeve 362 is connected to the bottom of the U-shaped plate by a semi-circular clamp. The threaded connecting pipe 363 movably passes through the sleeve 362 and extends into the double-layer threaded cap 361. 61 is threadedly connected to the threaded connecting pipe 363. When it is necessary to adjust the distance between the pressure sensor 32 and the limit block 34, that is, when it is necessary to adjust the pre-pressure stroke, the double-layer threaded cap 361 can be turned forward to gradually tighten it. At this time, the threaded connecting pipe 363 drives the positioning block 364 to gradually rise under the turning force, thereby increasing the distance between the pressure sensor 32 and the limit block 34. Even if the pre-pressure stroke increases during hot pressing, when it is necessary to reduce the pre-pressure stroke, the double-layer threaded cap 361 can be turned in the opposite direction.

[0022] The solder wire drawing mechanism 5 includes an electric slide 51 connected to a column and a base plate 11, a back plate 52 fixedly connected to the extended end of the electric slide 51, and a pneumatic finger 53 installed at the end of the back plate 52. In specific implementations, those skilled in the art can select a suitable model of electric slide 51 according to actual needs, such as GTH6A. The wire control assembly includes a connecting rod 54 fixedly connected to the outer end of the fixed section of the electric slide 51, an H-shaped guide plate 55 fastened to the end of the connecting rod 54 by bolts, and a guide tube 56 fastened to the end of the H-shaped guide plate 55 near the pneumatic finger 53 by bolts. The end of the guide tube 56 faces the pneumatic finger 53. In specific implementations, those skilled in the art can select a suitable model of pneumatic finger 53 according to actual needs, such as MHL2-2. Models such as 0D-Y59A2 and MHL2-32D have an H-shaped guide plate 55 with a pressure plate 501 bolted to the upper part of the end away from the pneumatic finger 53. The end of the H-shaped guide plate 55 away from the pneumatic finger 53 also has a wire-passing hole coaxial with the guide tube 56. The movable end of the solder wire passes through the wire-passing hole, the gap between the pressure plate 501 and the bottom of the H-shaped guide plate 55, and the guide tube 56 in sequence and is clamped by the pneumatic finger 53. In use, the controller can control the electric slide 51 to extend, so that it drives the pneumatic finger 53 to approach the end of the solder wire at the guide tube 56 and controls the pneumatic finger 53 to clamp the end of the solder wire. Then, the controller can control the electric slide 51 to shorten, so that the solder wire can be pulled between the hot pressing platform 8 and the hot pressing head 33, so that it can contact the workpiece during hot pressing and complete the soldering.

[0023] In use, first adjust the pre-pressure stroke according to the type of workpiece to be welded. Specifically, by turning the double-layer threaded cap 361 in the forward or reverse direction, the threaded connecting pipe 363 will drive the positioning block 364 to gradually rise or fall under the turning force, thereby increasing or decreasing the distance between the pressure sensor 32 and the limit block 34, thus increasing or decreasing the pre-pressure stroke during hot pressing. This completes the preparation work before hot pressing and soldering of new types of workpieces. Then, place the workpiece to be hot pressed on the hot pressing platform 8, and make certain fine adjustments to the position of the workpiece through the two fine-adjustment platforms 7 so that the workpiece is directly below the hot pressing head 33. Then control the solder wire pulling mechanism 5 to work, so that the pneumatic finger 53 is aligned with the guide. The conduit 56 moves to one side and clamps the end of the solder wire. Then, the electric slide 51 is shortened to pull the solder wire between the hot press platform 8 and the hot press head 33, completing the preparation work for hot press soldering. Afterward, the vertical moving component 4 drives the hot press unit 3 to move down, so that the hot press head 33 squeezes the workpiece and the solder wire until the welding is completed. Compared with the prior art, this solution makes the position of the pressure sensor 32 adjustable by setting the pressure adjustment unit 36. When hot press welding different products, the height of the pressure sensor 32 can be adjusted according to the actual needs, so that the pre-pressure stroke is changed accordingly. Compared with the prior art, this effectively improves the applicability of this pulse hot press machine.

[0024] Second implementation method: This embodiment adds a friction-reducing ring 9 to the first embodiment, while the rest remains the same as the first embodiment.

[0025] The wire guide hole is equipped with a friction-reducing ring 9. The cross-section of the friction-reducing ring 9 is a flat T-shape, and the outward-facing end of the flat T-shape is arc-shaped. This allows the solder wire to make inclined contact with the surface of the friction-reducing ring 9 when it exits from the end of the spool 62 and reaches the wire guide hole. The arc surface of the friction-reducing ring 9 allows the inclined contact between the two to produce an arc transition, which can effectively protect the solder wire from stress concentration and prevent it from breaking.

[0026] like Figures 8-9 When the solder wire passes through the wire control assembly for a long time, its surface tension will cause the H-shaped conductor plate 55 to shift downwards to a certain extent. However, the initial magnitude of this shift is small and difficult to detect. This will cause the relative position of the solder wire and the workpiece on the hot press platform 8 to tilt to a certain extent, affecting the quality of the hot press welding. Figure 10Based on this, a pressure-sensitive coating 91 is coated on the arc end of the friction-reducing ring 9, and the pressure-sensitive coating 91 is located above the horizontal line. The angle between the lower edge of the pressure-sensitive coating 91 and the horizontal line is no more than 5°. When the h-shaped conductor plate 55 tilts downward at a small angle, the contact point between the solder wire and the friction-reducing ring 9 will shift upward to a certain extent, and then come into contact with the pressure-sensitive coating 91, causing it to change color. According to the color change, the staff can adjust the angle of the h-shaped conductor plate 55 in time and tighten it, thereby effectively reducing the defect rate of hot-press soldering.

[0027] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
