Description

Technical Field

[0001] The present invention relates to the technical field of test probe welding, and more specifically, to a novel automatic assembly device and method for test probes. Background Art

[0002] As a core tool in fields such as semiconductor manufacturing and electronic device detection, the accuracy and reliability of test probes directly affect the chip test efficiency and product quality. With the continuous improvement of the integration level of semiconductor devices, the probes need to adapt to smaller-sized PADs and higher-precision operation requirements. At the same time, the application scenarios of probes are constantly expanding, covering fields such as BTB / FPC connector testing, biomedical detection, and environmental monitoring, driving the continuous growth of the market demand for probes. Taking semiconductor test probes as an example, the global market size reached 765 million US dollars in 2023 and is expected to exceed 1 billion US dollars in 2029, with an average annual compound growth rate of 6.51%. In the automatic assembly operation of test probes, the welding operation is an important part.

[0003] During the use of existing welding devices, by fixing the connector, when welding, operators need to use auxiliary clamps to hold and limit the test probes. Due to the unsteadiness of the operators' hands, the insertion positions of different test probes into the sockets provided at the top of the connector vary during the welding process, resulting in uneven welding effects and affecting the stability of the production quality of test probes. Moreover, when the welding is completed, loose solder particles and dust remain on the surface of the welded parts and adhere to the surface of the connector, resulting in low measurement accuracy when assembling the test probes.

[0004] In view of this, we propose a novel automatic assembly device and method for test probes. Summary of the Invention

[0005] The purpose of the present invention is to provide a novel automatic assembly device for test probes to solve the problems raised in the above background art.

[0006] To achieve the above object, the object of the present invention is to provide a new type of automatic assembly device and method for test probes, including a support base and a strong magnetic stone. Above the support base, there is a water collecting box, and soapy water is contained inside the water collecting box. A rotating shaft is provided between the support base and the water collecting box, and a driven gear is provided on the surface of the rotating shaft. A servo motor is provided at the bottom of the support base, and a driving gear is provided at the output end of the servo motor. The rotation of the driving gear drives the driven gear to mesh and rotate. Above the water collecting box, there is a welding table, and a welding pen is provided at the center of the welding table. Limiting frames are provided on both sides of the surface of the welding table. A water tank is provided near one side of the limiting frame. A water pump is provided on one side of the water tank. An electromagnetic valve is provided at one end of the water pump connected to the water tank. A heat conducting block is provided on the side wall of the limiting frame, and the heat conducting block penetrates the side wall of the limiting frame into the inside of the water tank. A clamp is provided on the side of the limiting frame away from the heat conducting block, and the clamp is used to clamp and fix the connector. A limiting component is provided on the side wall of the limiting frame, and the limiting component is used to automatically limit the test probe. A through hole is provided on the side of the water tank close to the connector, and a spray head is provided at the end of the through hole. A sealing component is provided on the inner wall of the through hole, and the sealing component is used to seal the through hole. A flushing component is provided on the inner wall of the water tank. When the connector and the test probe are welded and then rotated to the unloading position, the flushing component is horizontally moved by the attraction of the strong magnetic stone to squeeze the soapy water inside the water tank, and the soapy water is discharged from the spray head through the sealing component to automatically flush the surface of the welded part.

[0007] As a further improvement of this technical solution, the limiting component includes a support block provided on the side wall of the limiting frame. Symmetric cylinder barrels are provided on both sides of the support block. A sliding column is slidably provided inside the cylinder barrel. A first elastic member is provided between the cylinder barrel and the sliding column.

[0008] As a further improvement of this technical solution, a pressing plate is provided on the side wall of the sliding column. The pressing plate increases the contact area with the side wall of the test probe, and a guiding block is provided on the top of the pressing plate.

[0009] As a further improvement of this technical solution, the flushing component includes a sliding plate provided on one side of the inner wall of the water tank. A hollow column is provided at the end of the sliding plate. An iron block is provided at the end of the hollow column. When the iron block moves to the position of the strong magnetic stone, the iron block is attracted by the magnetic force and pulls the sliding plate to slide on the inner wall of the water tank through the hollow column.

[0010] As a further improvement of this technical solution, a second elastic member is provided between the water tank and the end of the hollow column. In the natural state, the hollow column is driven by the acting force of the second elastic member to move to fit the inner wall of the water tank.

[0011] As a further improvement of this technical solution, symmetric racks are provided on both sides of the end of the skateboard. The ends of the racks away from the skateboard are slidably arranged in the limiting groove blocks on both sides of the inner wall of the water tank. At the same time, the moving skateboard is limited by the limiting blocks.

[0012] As a further improvement of this technical solution, meshing gears are rotatably arranged on both sides of the inner wall of the water tank. Stirring fan blades are arranged at the ends of the meshing gears. When the racks move, they drive the meshing gears to rotate.

[0013] As a further improvement of this technical solution, the skateboard is made of PVC plastic.

[0014] As a further improvement of this technical solution, the sealing assembly includes a support rod arranged on the inner wall of the through hole. A baffle is rotatably arranged on the surface of the support rod. A third elastic member is arranged on the surface of the support rod. The two ends of the third elastic member are respectively connected to the baffle and the through hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this new type of automatic test probe assembly equipment, by arranging heat-conducting blocks on the inner wall of the limiting frame, during the welding process of the welded parts, the heat generated during the welding process is introduced into the soapy water inside the water tank through the heat-conducting blocks, thereby heating it. After the welding is completed, under the action of the strong magnetic attraction of the iron magnet, the skateboard at the end of the hollow column squeezes the soapy water inside the water tank during the movement process. The heated soapy water is sprayed through the spray head arranged at the end of the water tank, thereby automatically cleaning the surface of the welded parts and improving the measurement accuracy of the test probe.

[0016] 2. In this new type of automatic test probe assembly equipment, during the flushing process of the welded parts, since the heat-conducting blocks are arranged near the top of the water tank, resulting in a large temperature difference inside the water tank. During the movement of the racks, they drive the meshing gears arranged on both sides of the inner wall of the water tank to rotate. Stirring fan blades are arranged at the ends of the meshing gears. Under the agitation of the stirring fan blades, the soapy water inside the water tank is mixed evenly more quickly, avoiding the precipitation of cleaning substances in the soapy water, thereby improving the cleaning efficiency of the solder loose particles and dust generated on the surface of the welded parts.

[0017] 3. In the new type of automatic assembly equipment for test probes, the connector is limited and fixed by a fixture. The end of the test probe is inserted into the top socket of the connector melted with solder. When the test probe moves under pressure, the side wall of the test probe squeezes the pressure plate. When the pressure plate is subjected to an external squeezing force, it presses the sliding column. The sliding column slides on the inner wall of the cylinder barrel and squeezes and deforms the first elastic member at the same time. When the placement of the test probe is completed, the external force is stopped. At this time, the first elastic member pushes the sliding column under the action of the restoring force, so that the pressure plate provided at the end of the sliding column automatically squeezes and limits both sides of the test probe. By limiting the test probe, it can ensure that the test probe is inserted into the socket at the top of the connector at the same position, thus guaranteeing the welding quality.

[0023] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0024] The purpose of this embodiment is to provide a new type of automatic assembly device for test probes. Refer to Figures 1-11As shown in the figure, it includes a support base 100 and a strong magnet 104. Above the support base 100, there is a water collection box 200. The inside of the water collection box 200 contains soapy water. There is a rotating shaft between the support base 100 and the water collection box 200. On the surface of the rotating shaft, there is a driven gear 103. At the bottom of the support base 100, there is a servo motor 101. At the output end of the servo motor 101, there is a driving gear 102. The rotation of the driving gear 102 drives the driven gear 103 to engage and rotate. Above the water collection box 200, there is a welding table 201. At the center of the welding table 201, there is a welding pen 205. On both sides of the surface of the welding table 201, there are limit frames 202. Near one side of the limit frame 202, there is a water tank 206. On one side of the water tank 206, there is a water pump 207. One end of the water pump 207 connected to the water tank 206 is provided with an electromagnetic valve. On the side wall of the limit frame 202, there is a heat conducting block 203. The heat conducting block 203 penetrates through the side wall of the limit frame 202 into the inside of the water tank 206; On the side of the limit frame 202 away from the heat conducting block 203, there is a fixture 204. The fixture 204 is used to clamp and fix the connector. On the side wall of the limit frame 202, there is a limit component 300. The limit component 300 is used to automatically limit the test probe. On the side of the water tank 206 close to the connector, there is a through hole. At the end of the through hole, there is a spray head 208. On the inner wall of the through hole, there is a sealing component 500. The sealing component 500 is used to seal the through hole. On the inner wall of the water tank 206, there is a flushing component 400. When the connector and the test probe are welded and rotated to the unloading position, the flushing component 400 is attracted by the strong magnet 104 and moves horizontally to squeeze the soapy water inside the water tank 206. The soapy water is discharged from the spray head 208 through the sealing component 500 to automatically flush the surface of the welded part.

[0025] The improvement of this embodiment lies in that: by arranging a heat conducting block 203 on the inner wall of the limit frame 202, during the welding process of the welded part, the heat generated during the welding process is introduced into the soapy water inside the water tank 206 through the heat conducting block 203, so as to heat it. After the welding is completed, the iron block 403 is affected by the magnetic attraction of the strong magnet 104, so that the sliding plate 401 at the end of the hollow column 402 squeezes the soapy water inside the water tank 206 during the moving process. The heated soapy water is sprayed through the spray head 208 provided at the end of the water tank 206, so as to automatically clean the surface of the welded part and improve the measurement accuracy of the test probe.

[0026] During the flushing process of the welded part, since the heat conducting block 203 is arranged near the top of the water tank 206, the water temperature difference inside the water tank 206 is large. During the movement of the rack 405, the meshing gears arranged on both sides of the inner wall of the water tank 206 are driven to rotate. Stirring fan blades 209 are arranged at the ends of the meshing gears. Under the agitation of the stirring fan blades 209, the soap water inside the water tank 206 is mixed evenly more quickly, preventing the cleaning substances in the soap water from precipitating, thereby improving the cleaning efficiency of the loose solder particles and dust generated on the surface of the welded part.

[0027] During the flushing process of the welded part, since the heat conducting block 203 is arranged near the top of the water tank 206, the water temperature difference inside the water tank 206 is large. During the movement of the rack 405, the meshing gears arranged on both sides of the inner wall of the water tank 206 are driven to rotate. Stirring fan blades 209 are arranged at the ends of the meshing gears. Under the agitation of the stirring fan blades 209, the soap water inside the water tank 206 is mixed evenly more quickly, preventing the cleaning substances in the soap water from precipitating, thereby improving the cleaning efficiency of the loose solder particles and dust generated on the surface of the welded part.

[0028] During the manufacturing process of the test probe, the connector and the test probe need to be welded. During the welding process, since the test probe is in an arc shape as a whole, when the test probe is inserted into the connector socket, the operator needs to support the test probe to prevent the position of the test probe from shifting during the welding process, which affects the welding quality. Therefore, the limiting component 300 includes a support block 301 arranged on the side wall of the limiting frame 202. Symmetric cylinder barrels 302 are arranged on both sides of the support block 301. A sliding column 304 is slidably arranged on the inner wall of the cylinder barrel 302. A first elastic member 303 is arranged between the cylinder barrel 302 and the sliding column 304. A pressing plate 305 is arranged on the side wall of the sliding column 304. The pressing plate 305 increases the fitting area with the side wall of the test probe. A guiding block 306 is arranged on the top of the pressing plate 305. During the welding process, the connector placed on the inner wall of the limiting frame 202 is quickly fixed by the fixture 204. The end of the test probe is placed in the socket on the top of the connector. The top of the test probe is pressed downward along between the guiding blocks 306, so that the side wall of the test probe presses the pressing plate 305. When the pressing plate 305 is subjected to an external pressing force, it presses the sliding column 304. The sliding column 304 slides on the inner wall of the cylinder barrel 302 while deforming the first elastic member 303 by extrusion. When the placement of the test probe is completed, the external force is stopped. At this time, the first elastic member 303 pushes the sliding column 304 under the action of the restoring force, so that the pressing plate 305 arranged at the end of the sliding column 304 automatically presses and limits both sides of the test probe, liberating the hands of the operator. At the same time, during the process of limiting the test probe, it can ensure that the test probe is inserted into the socket arranged at the top of the connector at the same position, ensuring the welding quality.

[0029] During the soldering process of the connector and the test probe, loose solder particles and dust generated adhere to the surface of the connector. During the assembly process of the test probe, in order to improve the accuracy of the test probe measurement, the soldered parts after soldering are usually placed in a cleaning tank for cleaning. Since the soldered parts are prone to collide with each other during the cleaning process, deformation occurs on the surface of the soldered parts, affecting the accuracy of the pressure measurement after the later assembly. Therefore, the flushing assembly 400 includes a slide plate 401 provided on one side of the inner wall of the water tank 206. A hollow column 402 is provided at the end of the slide plate 401, and an iron block 403 is provided at the end of the hollow column 402. When the iron block 403 moves to the strong magnet 104, the iron block 403 receives a magnetic attraction force and pulls the slide plate 401 to slide on the inner wall of the water tank 206 through the hollow column 402. When the soldering is completed, the output end of the servo motor 101 drives the driving gear 102 to rotate. The driving gear 102 meshes with the driven gear 103 provided on the surface of the rotating shaft, causing the water collecting box 200 to rotate 180° in the horizontal direction. After the rotation is completed, the iron block 403 is driven by the magnetic attraction force of the strong magnet 104 to drive the slide plate 401 at the end of the hollow column 402 to move horizontally. During the movement of the slide plate 401, the soapy water inside the water tank 206 is squeezed, causing the soapy water to flow out through the through hole at the end of the water tank 206. The spraying direction of the spray head 208 at the through hole is adjusted, so as to automatically clean the surface of a single soldered part. At the same time, since the heat conducting block 203 penetrates into the water tank 206, during the soldering process, the heat generated during soldering is conducted through the heat conducting block 203 to heat the soapy water inside the water tank 206, improving the cleaning power of the soapy water on the soldered parts.

[0030] When the cleaning of the soldered parts is completed, in order to facilitate the quick replenishment of soapy water inside the water tank 206 and facilitate the subsequent cleaning of the soldered parts fixed again inside the limiting frame 202, therefore, a second elastic member 404 is provided between the water tank 206 and the end of the hollow column 402. In the natural state, the hollow column 402 is driven by the acting force of the second elastic member 404 to move to fit the inner wall of the water tank 206. By releasing the clamping of the soldered parts by the clamp 204 and clamping and fixing the soldered parts to be soldered, when the water collecting box 200 rotates, the suction force of the strong magnet 104 on the iron block 403 disappears, causing the hollow column 402 to reset under the action of the second elastic member 404. The water pump 207 is started to pump the soapy water inside the water collecting box 200 into the water tank 206. Since the hollow column 402 is driven by the acting force of the second elastic member 404 to drive the slide plate 401 to reset, the water storage space inside the water tank 206 remains unchanged. When the soldered parts need to be cleaned subsequently, there is sufficient soapy water stored inside the water tank 206 to maintain the cleanliness of the surface cleaning of the soldered parts, thus ensuring the repeated cleaning efficiency of the soldered parts.

[0031] When the iron block 403 is driven by the magnetic attraction force of the strong magnet 104 to move the hollow column 402, in order to avoid the position deviation of the magnetic attraction force received by the iron block 403, resulting in the position deviation of the slide plate 401 provided at the end of the hollow column 402 when it moves and being stuck on the inner wall of the water tank 206, affecting the automatic cleaning of the surface of the welded part. Therefore, symmetric racks 405 are provided on both sides of the end of the slide plate 401. The ends of the racks 405 away from the slide plate 401 are slidably arranged in the limit groove blocks on both sides of the inner wall of the water tank 206. At the same time, the moving slide plate 401 is limited by the limit block. Since the racks 405 are slidably arranged in the limit groove blocks, during the movement of the slide plate 401, the position of the slide plate 401 is limited through the racks 405, avoiding the position deviation during the movement of the slide plate 401, so that the slide plate 401 at the end of the hollow column 402 always remains horizontal during the movement, improving the stability of the cleaning of the surface of the welded part.

[0032] During the cleaning process of the surface of the welded part, the cleaning substance of normal-temperature soapy water is prone to precipitation. Heating the soapy water can improve the cleaning efficiency of the welded part. Therefore, meshing gears are rotatably arranged on both sides of the inner wall of the water tank 206, and stirring fan blades 209 are provided at the ends of the meshing gears. When the racks 405 move, they drive the meshing gears to rotate. Since the end of the heat conduction block 203 penetrates through the side wall of the limit frame 202 to the inside of the water tank 206, during the welding process of the connector and the test probe, a large amount of heat will be generated. Since the side wall of the heat conduction block 203 is attached to the side wall of the connector, the heat energy will be transmitted to the soapy water inside the water tank 206 through the heat conduction block 203, thereby heating the soapy water. During the flushing process of the welded part, since the heat conduction block 203 is arranged near the top of the water tank 206, resulting in a large temperature difference inside the water tank 206. During the movement of the racks 405, they drive the meshing gears arranged on both sides of the inner wall of the water tank 206 to rotate. Since stirring fan blades 209 are provided at the ends of the meshing gears, therefore, under the agitation of the stirring fan blades 209, the soapy water inside the water tank 206 is mixed evenly more quickly, improving the cleaning efficiency of the loose particles and dust generated on the surface of the welded part.

[0033] When manufacturing small test probes, the sizes of the connectors and test probes are small. When flushing the solder and dust on their surfaces, a large amount of soapy water is not required, and the internal volume of the water tank 206 does not need to be too large. In order to avoid the weight of the sliding plate 401 being too large, making it difficult for the magnetic suction force of the powerful magnetic stone 104 to generate sufficient suction force on the iron block 403, resulting in the device being unable to automatically perform the cleaning operation. Therefore, in order to avoid excessive resistance caused by too much soapy water inside the sliding plate 401 when the iron block 403 is subjected to the suction force of the powerful magnetic stone 104, affecting the normal movement of the sliding plate 401. Therefore, the sliding plate 401 is made of PVC plastic material. Since the PVC material is light in weight and the hollow column 402 inside is a hollow structure, the gravity of the hollow column 402 is reduced. Thus, when the iron block 403 moves to the powerful magnetic stone 104 and is subjected to the magnetic suction force, the iron block 403 can drive the hollow column 402 to move horizontally, thereby ensuring the automatic cleaning operation of the surface of the welded part.

[0034] In order to avoid the soapy water inside the water tank 206 flowing out from the through hole during the welding process, affecting the welding effect. Therefore, the sealing component 500 includes a support rod 501 provided on the inner wall of the through hole. A baffle 502 is rotatably provided on the surface of the support rod 501. A third elastic member 503 is provided on the surface of the support rod 501. The two ends of the third elastic member 503 are respectively connected to the baffle 502 and the through hole. The baffle 502 rotates on the surface of the support rod 501. In the natural state, the baffle 502 is subjected to the acting force of the third elastic member 503, so that the baffle 502 is perpendicular to the horizontal plane to block the through hole, thereby avoiding the outflow of soapy water during the welding operation and ensuring the welding effect. When cleaning the loose particles and dust on the surface of the welded part, the powerful magnetic stone 104 attracts the iron block 403 through magnetic suction, so that the hollow column 402 at the end of the iron block 403 drives the sliding plate 401 to move horizontally. During the movement of the sliding plate 401, the soapy water inside the water tank 206 is squeezed, causing the baffle 502 to rotate on the surface of the support rod 501, and the soapy water is sprayed out from the spray head 208. When the squeezing of the soapy water inside the water tank 206 stops, the baffle 502 is reset under the action of the third elastic member 503 to block the through hole.

[0035] In summary, the working principle of the present invention is as follows: Place the connector inside the limit frame 202, and use the fixture 204 to limit and fix the connector. Insert the end of the test probe into the top socket of the connector melted with solder. When the test probe moves under pressure, the side wall of the test probe squeezes the pressure plate 305. When the pressure plate 305 is subjected to an external squeezing force, it presses the sliding column 304. The sliding column 304 slides on the inner wall of the column cylinder 302 and simultaneously squeezes and deforms the first elastic member 303. When the placement of the test probe is completed, the external force is stopped. At this time, the first elastic member 303 pushes the sliding column 304 under the action of the restoring force, so that the pressure plate 305 provided at the end of the sliding column 304 automatically squeezes and limits both sides of the test probe. At this time, take the soldering pen 205 to perform soldering, which liberates the hands of the operator and reduces the labor intensity. During the soldering process, another operator clamps and fixes the welded part on the limit frame 202 on the surface of the soldering table 201 away from the soldering side. By alternately fixing the welded parts on the limit frames 202 on both sides of the surface of the soldering table 201, the rapid soldering of the welded parts is realized, and the soldering efficiency is improved. During the soldering process, since the side wall of the heat conduction block 203 is in contact with the connector, the heat generated during the soldering process is introduced into the soapy water inside the water tank 206 through the heat conduction block 203, thereby heating it. After the soldering is completed, the output end of the servo motor 101 drives the driving gear 102 to rotate. The driving gear 102 meshes with the driven gear 103 provided on the surface of the rotating shaft, so that the water collecting box 200 rotates 180° in the horizontal direction. After the rotation is completed, the iron block 403 is driven by the magnetic attraction of the strong magnet 104 to horizontally move the slide plate 401 at the end of the hollow column 402. The slide plate 401 is provided with a rack 405 at its end. During the movement of the rack 405, it drives the meshing gears provided on both sides of the inner wall of the water tank 206 to rotate. Since the end of each meshing gear is provided with a stirring fan blade 209, therefore, under the agitation of the stirring fan blade 209, the soapy water inside the water tank 206 is mixed evenly more quickly, avoiding the precipitation of the cleaning substances in the soapy water. During the movement of the slide plate 401, the soapy water inside the water tank 206 is squeezed, so that the soapy water flows out through the through hole at the end of the water tank 206. Adjust the spraying direction of the spray head 208 at the through hole, thereby automatically cleaning the surface of the welded part and improving the cleaning efficiency of the loose particles and dust generated on the surface of the welded part.

10. The method of using the new type of automatic assembly equipment for test probes according to any one of claims 1-9, characterized in that: S1: By placing the connector inside the limit frame and limiting and fixing the connector through the clamp, inserting the end of the test probe into the socket at the top of the connector melted with solder. When the test probe moves under pressure, the side wall of the test probe presses the pressing plate. When the pressing plate is subjected to an external pressing force, it presses the sliding column. The sliding column slides on the inner wall of the cylindrical barrel and deforms the first elastic member at the same time. When the placement of the test probe is completed, the external force is stopped. At this time, the first elastic member pushes the sliding column under the action of the restoring force, so that the pressing plate provided at the end of the sliding column automatically presses and limits both sides of the test probe; S2: Weld it by taking the soldering pen. During the welding process, another operator holds and fixes the welded part on the limiting frame on the surface of the welding table away from the welding side. By alternately fixing the welded parts on the limiting frames on both sides of the welding table surface, rapid welding of the welded parts is achieved. During the welding process, since the side wall of the heat conduction block is in contact with the connector, the heat generated during the welding process is conducted into the soapy water inside the water tank through the heat conduction block, thereby heating it; S3: After welding is completed, the output end of the servo motor drives the driving gear to rotate. The driving gear meshes with the driven gear provided on the surface of the rotating shaft, causing the water collecting box to rotate horizontally. After the rotation is completed, the iron block is driven by the magnetic suction force of the strong magnet to drive the slide plate at the end of the hollow column to move horizontally. A rack is provided at the end of the slide plate. During the movement of the rack, it drives the meshing gears provided on both sides of the inner wall of the water tank to rotate. Since stirring fan blades are provided at the ends of the meshing gears, therefore, under the agitation of the stirring fan blades, the soapy water inside the water tank is mixed evenly more quickly, avoiding the precipitation of cleaning substances in the soapy water. During the movement of the slide plate, the soapy water inside the water tank is squeezed, causing the soapy water to flow out through the through hole at the end of the water tank, and adjusting the spraying direction of the spray head at the through hole.
