Description

Technical Field

[0001] The present invention relates to the technical field of probe assembly, and in particular to a probe assembly device. Background Art

[0002] In the electronic manufacturing process, probes are important electrical connection devices and are widely used in various test and measurement equipment. The probe assembly process usually involves the precise assembly of multiple components, including the probe body, spring, and needle holder. In the prior art, the assembly of probes is mainly completed by manual operation or semi-automatic assembly equipment. However, these technologies have certain limitations when facing increasingly complex probe structures and diversified application requirements.

[0003] Common existing probe assembly technologies include manual assembly or semi-automatic technology. Manual assembly of probes is a traditional assembly method. The operator assembles the various components of the probe, such as the needle body, spring, needle seat, etc., through fixtures or hand tools. This method is suitable for small-batch production or probes with low precision requirements. Operators can flexibly adjust according to the design of different probes, but the manual assembly speed is slow and it is difficult to meet the needs of large-scale production. Semi-automatic technology uses a manipulator or automatic fixture to assemble the various components of the probe together. These devices can usually achieve higher efficiency and are suitable for mass production. The operator places the parts on the assembly machine in advance, and the machine completes the subsequent assembly actions. Existing semi-automatic assembly equipment is usually designed for a single or specific type of probe and cannot flexibly cope with probes of multiple different diameters.

[0004] To this end, we proposed a probe assembly device, which aims to solve the problems of low assembly efficiency, insufficient precision and poor adaptability existing in the existing technology.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] refer to Figure 1-Figure 10 , a probe assembly device, comprising:

[0048] Assembling housing 100;

[0049] An assembly bracket 101 is disposed on the assembly housing 100, and a plurality of top openings 102 for separating the probes are formed on the assembly bracket 101;

[0050] A plurality of positioning plates 103 are arranged on the assembly bracket 101, and are located at both ends of the top opening 102. A plurality of positioning convex plates 104 are arranged on the positioning plate 103, and a plurality of positioning rods 105 are also arranged on the positioning plate 103. An elastic member 106 is arranged between the positioning convex plates 104 and the positioning plate 103;

[0051] Two supporting brackets 107 disposed in the top opening 102 are used to support the needle tube part and the needle part of the probe;

[0052] Two positioning frames 108 disposed in the top opening 102 are located between the two supporting brackets 107;

[0053] A positioning component disposed between the positioning plate 103 and the positioning convex plate 104, used to rotate the positioning rod 105 and lock the positioning convex plate 104 and the positioning rod 105 when the positioning convex plate 104 moves to a predetermined position toward the positioning plate 103;

[0054] A moving component disposed between the assembly housing 100 and the positioning frame 108, used to move the two positioning frames 108 away from each other;

[0055] The moving component can move the positioning frame 108 laterally along a predetermined path. When the positioning frame 108 moves to a first predetermined position, the positioning frame 108 can move vertically upward by a predetermined distance. When the positioning frame 108 moves to a second predetermined position, the position of the supporting bracket 107 can be displaced downward. When the positioning frame 108 moves to a third predetermined position, the positioning frame 108 can move vertically downward by a predetermined distance.

[0056] The moving component can also move the position of the positioning plate 103 after the positioning frame 108 moves vertically downward to the third predetermined position, and the positioning plate 103 can unlock the positioning convex plate 104 when it moves to the predetermined position;

[0057] By setting up the assembly bracket 101, the probe barrel part and the needle part to be assembled can be placed on the two supporting brackets 107 in the top opening 102 respectively by using a manipulator or other fixture. There are two supporting brackets 107 to receive the needle part and the needle tube component. A plurality of top openings 102 are opened on the assembly bracket 101, and a plurality of groups of probe components can be placed respectively. Not only can a plurality of groups of probe components be placed at the same time to improve assembly efficiency, but batch operation can also be realized to reduce repeated processes in a single assembly process. In addition, the design of the top opening 102 makes the assembly bracket 101 highly flexible and can adapt to probe components of different sizes or specifications. In specific operations, it is only necessary to adjust the position of the opening and the assembly end on the probe component. Through this modular layout, the number and arrangement of the openings can be adjusted according to actual needs, thereby further improving the versatility and assembly efficiency of the equipment and adapting to probe assembly tasks of different batches and types. This design greatly improves the speed and consistency of assembly work. When in use, the moving component can be started, and the moving component moves the two positioning frames 108 to move them away from each other. When the positioning frame 108 moves to the first predetermined position along the predetermined path, the positioning frame 108 can move upward by a predetermined distance to adapt to the position of the probe component. The purpose of this setting is to ensure that the height of the positioning frame 108 is lower than the probe component in the initial state, and a lifting action can be generated when it moves to the first predetermined position to adapt to the position of the probe component, ensuring that the probe component can be pushed in the subsequent continued movement. The continuous movement of the positioning frame 108 pushes the probe component so that the probe component can contact the positioning convex plate 104. The continuous movement of the positioning frame 108 can press the position of the positioning convex plate 104 through the probe component. When the positioning convex plate 104 moves toward the positioning plate 103, the arranged positioning component can rotate a plurality of positioning rods 105, and one end of the probe is at the top of the positioning convex plate 104. After contact, its horizontal angle is limited, and one end of the multiple positioning rods 105 gradually approaches the axis of the positioning plate 103. At this time, the horizontal position of the probe component can be adjusted to make the axis of the probe component coaxial with the positioning convex plate 104 and the positioning plate 103, so that the needle tube part and the needle head part can be coaxial, and no misalignment will occur when the needle tube and the needle head are assembled later. Through this precise coaxial assembly method, not only can the subsequent operation steps be simplified, but also the rework or scrap rate caused by misalignment can be reduced, and the assembly efficiency and product quality can be further improved. The flexible adjustment mechanism of the positioning convex plate 104 and the positioning rod 105 makes it possible to ensure high-precision assembly of the needle tube and the needle head through precise coaxial adjustment even when facing probe components of different diameters. Disalignment problems caused by size differences can be avoided, and the needle tube and the needle head can be automatically adapted to probe components of various diameters, which greatly reduces the time for manual adjustment and adjustment of different assembly parameters, and improves overall production efficiency.In addition, when the probe component presses the position of the positioning protrusion 104 through the movement of the positioning frame 108, the positioning frame 108 is in the second predetermined position. At this time, the support bracket 107 used to support the probe component can be moved downward to avoid the positioning rod 105 being unable to adjust the height of the probe component when coaxially positioning and clamping the probe component due to the existence of the support bracket 107. For example, when the axis height of the probe component is higher than the positioning protrusion 104, the avoidance of the support bracket 107 allows the positioning rod 105 to quickly and flexibly adjust the The probe component is height-adjusted to ensure assembly accuracy. The dynamic support bracket 107 design ensures that the relative position relationship between the probe component and the positioning convex plate 104 is accurately maintained, so that higher coaxiality can be achieved during the clamping process, thereby improving the overall assembly quality. When the positioning frame 108 moves to the third predetermined position, the positioning convex plate 104 is pressed by the probe component, and the positioning convex plate 104 moves to the predetermined position toward the positioning plate 103, the elastic member 106 is compressed, and the positioning component can lock the positions of multiple positioning rods 105, and multiple positioning rods 105 can be used. The clamping force of the positioning rod 105 clamps and positions the probe component, and at this time, the positioning frame 108 can move downward by a predetermined distance to avoid the position of the probe component. After the positioning frame 108 moves downward to avoid, the position of the movable positioning plate 103 can be moved. The positioning plates 103 at both ends of the top opening 102 move closer to each other, and the needle part and the needle tube part of the probe can be partially sleeved. When the positioning plate 103 moves to the predetermined position, the positioning component can release the lock of the positioning convex plate 104, and the elastic member 106 releases the potential energy. The potential energy released by 6 will push the positioning convex plate 104 to move, and the positioning convex plate 104 will push the probe parts. Through the instantaneous release of the elastic member 106, the probe parts can be quickly riveted. The riveting process utilizes the power of the elastic member 106 to ensure that the connection between the probe parts is tighter, and the strength and stability of the connection are enhanced, thereby improving the reliability of the probe in subsequent use. In summary, by setting the assembly bracket 101 and its modular design, not only the efficient and flexible assembly of the probe parts is achieved, but also the accuracy and consistency of the assembly process are improved. The design of multiple top openings 102 supports the simultaneous processing of multiple groups of probes, reduces repeated processes, and improves the efficiency of mass production. The dynamic movement of the positioning frame 108 and the avoidance function of the supporting bracket 107 ensure the coaxiality of the probe parts and significantly reduce the misalignment problem caused by size differences. In addition, the application of the elastic member 106 makes the riveting process faster and more stable, thereby improving the quality and reliability of the product. This series of innovative designs not only simplifies and automates the assembly process, but also improves the overall production efficiency, solving the problem that the probe assembly equipment in the prior art cannot flexibly cope with probes of various diameters.

[0058] As a further solution of the present invention, the positioning component includes a connecting shaft 200 slidably connected to the positioning plate 103, a first spring 201 is connected between the connecting shaft 200 and the positioning plate 103, a first rack 202 is connected to the connecting shaft 200, a first gear 203 meshing with the first rack 202 is connected to the positioning rod 105, and a connecting rod 204 rotatably connected to the connecting shaft 200 is rotatably connected to one side of the positioning convex plate 104;

[0059] By setting the first spring 201, the first spring 201 can support the position of the first connecting shaft 200 and the first rack 202, ensuring that the positioning rod 105 is arranged on the positioning plate 103 at a certain angle in the initial state, and the elastic member 106 can limit the position of the positioning protrusion 104, so that there is a certain distance between it and the positioning plate 103. When the positioning frame 108 pushes the probe component to make the probe component press the positioning protrusion 104, the positioning protrusion 104 moves to compress the elastic member 106 and compress the position of the connecting rod 204. The connecting rod 204 can push the connecting shaft 200 and the first rack 202 on the connecting shaft 200 to move. The movement of the first rack 202 can rotate the positioning rod 105 through the first gear 203, thereby achieving the purpose of allowing multiple positioning rods 105 to approach the central axis of the positioning protrusion 104, and positioning and clamping the probe component, thereby achieving accurate clamping and stable positioning of the probe component. The rotation of the positioning rod 105 makes one end of the positioning rod 105 gradually approach the probe component, ensuring that the axis of the probe is coaxial with the positioning convex plate 104, further improving the assembly accuracy. When multiple positioning rods 105 are brought together at the same time, they can effectively surround the probe component, forming a uniform clamping force, reducing the risk of misalignment caused by uneven clamping.

[0060] As a further solution of the present invention, the first rack 202 includes a slide rail 205 connected to the connecting shaft 200, a slider 206 is slidably connected in the slide rail 205, a plurality of tooth blocks 207 are connected to the slider 206, a slot 208 is provided on the inner wall of the slide rail 205, and spring rods 209 sleeved with the slot 208 are connected to both sides of the slider 206, and one end of the spring rod 209 and the slot 208 are semi-spherical;

[0061] By setting the spring rod 209, the spring rod 209 can use its own potential energy to fit with the slot 208 and form a certain friction force. When the connecting rod 204 pushes the connecting shaft 200 to move, the slide rail 205 can move the slider 206 and the tooth block 207 through the friction between the slot 208 and the spring rod 209. At this time, the first gear 203 and the positioning rod 105 can rotate. For a probe component with a larger diameter, the rotation angle of the positioning rod 105 is shortened, and the distance moved by the slider 206 is correspondingly increased. When the positioning protrusion 104 gradually approaches the positioning plate 103, the slot 208 can compress the spring rod 209, causing the spring rod 209 to shrink and disengage from the slot 208, that is, the slide rail 205 slides on the slider 206. Even if the positioning rod 105 is rotated to the extreme angle, the positioning protrusion 104 can still continue to move to ensure that it can be locked later. Through this mechanism, the needs of probes of different specifications are met, and the problem of uneven clamping caused by different diameters of probe components during assembly is effectively solved.

[0062] As a further solution of the present invention, the positioning component further includes a connecting tube 210 connected to one side of the positioning plate 103, a magnet 211 is slidably connected in the connecting tube 210, and an iron rod 212 slidably connected to the positioning plate 103 is connected to one side of the positioning convex plate 104;

[0063] By setting the iron rod 212, the iron rod 212 can limit the position of the positioning protrusion 104. When the positioning protrusion 104 moves toward the positioning plate 103, the iron rod 212 can gradually approach the magnet 211. When the positioning protrusion 104 moves to the limit position, the iron rod 212 can contact the magnet 211. The magnet 211 can use its magnetic connection force to overcome the force of the elastic member 106 and the first spring 201 to connect with the iron rod 212 and limit the position of the iron rod 212, thereby achieving the purpose of locking the position of the positioning protrusion 104 and the angle of the positioning rod 105. While the positioning protrusion 104 and the positioning rod 105 remain fixed, the magnet 211 in the connecting tube 210 can also provide the necessary flexibility. During the assembly process, the operator only needs to move the magnet 211 to release the attraction between the iron rod 212 and the magnet 211. After the attraction between the iron rod 212 and the magnet 211 is released, the elastic member 106 immediately releases the stored potential energy and quickly pushes the positioning protrusion 104 forward. This instantaneous release of force can complete the riveting process at an appropriate speed and strength. In this way, the instantaneous force of the elastic member 106 allows the probe components to be quickly and firmly combined together, thereby improving the efficiency of riveting and the strength of the connection. This design ensures that during the assembly process, the probe components can be accurately positioned and quickly assembled, avoiding time delays and errors caused by manual operation.

[0064] As a further solution of the present invention, the moving component includes a plurality of rotating shafts 300 rotatably connected to the assembly housing 100, a traction rope 301 is connected to the rotating shaft 300, a connecting frame 302 is provided on the positioning frame 108, one end of the traction rope 301 is connected to the connecting frame 302, the bottom of the assembly bracket 101 is connected to a limiting frame 303, and the connecting frame 302 is slidably connected to the limiting frame 303;

[0065] By setting the rotating shaft 300, the rotating shaft 300 can be rotated when in use. The rotation of the rotating shaft 300 can reel in the traction rope 301. When the traction rope 301 is reeled in, it can pull the position of the connecting frame 302. The connecting frame 302 is forced to move and can drive the positioning frame 108 to move, thereby achieving the purpose of moving the positioning frame 108 toward the probe component and pushing the probe component to its position.

[0066] As a further solution of the present invention, the connecting frame 302 includes a connecting plate 304 slidably connected to the bottom of the positioning frame 108, the connecting plate 304 is slidably connected to the limiting frame 303, a second spring 305 is connected between the connecting plate 304 and the positioning frame 108, a traction frame 306 is slidably connected to the bottom of the connecting plate 304, a traction plate 307 is slidably connected to the bottom of the traction frame 306, the traction rope 301 is connected to the traction plate 307, grooves 308 are respectively provided on both sides of the traction frame 306, a damping rod 309 is slidably connected in the groove 308, a third spring 310 is connected between the damping rod 309 and the groove 308, a damping groove 311 matched with the damping rod 309 is provided on the connecting plate 304, the damping groove 311 is a semi-spherical groove, and one end of the damping rod 309 matched with the damping groove 311 is semi-spherical, and a fourth spring 312 is connected between the traction plate 307 and the limiting frame 303;

[0067] By setting a limit frame 303, the limit frame 303 has a slope. In the initial state, the connecting plate 304 is at the lowest end of the limit frame 303. When the traction rope 301 is wound, the traction plate 307 can be pulled. The movement of the traction plate 307 and the traction frame 306 can allow the connecting plate 304 to move along the path of the limit frame 303 through the friction between the damping rod 309 and the damping groove 311. In the initial movement, the connecting plate 304 will move upward along the slope section of the limit frame 303, so that the positioning frame 108 can adapt to the height of the probe accessory. When the positioning frame 108 continues to move, the probe accessory can be released. The damping rod 309 and the damping groove 311 can be firmly matched through the third spring 310, which can overcome the elastic force. The force of the sexual member 106 and the first spring 201 allows the probe accessory to push the positioning protrusion 104 to move. When the positioning protrusion 104 moves to the extreme position, the rotating shaft 300 continues to rotate and reel in the traction rope 301. When the traction plate 307 is subjected to traction, the force of the third spring 310 can be overcome, and the damping rod 309 contracts and the third spring 310 is compressed. The damping rod 309 is disengaged from the damping groove 311, and the traction frame 306 can slide at the bottom of the connecting plate 304. When the positioning frame 108 moves to the extreme position, the rotating shaft 300 can continue to rotate to adapt to probe accessories of different lengths. This flexibility greatly improves the reliability of the entire assembly process and ensures the efficient assembly of probe accessories of different lengths.

[0068] As a further solution of the present invention, the supporting bracket 107 is slidably connected to the limiting bracket 303, a fifth spring 400 is connected between the supporting bracket 107 and the limiting bracket 303, a top contact strip 401 is connected to the bottom of the supporting bracket 107, and a top contact block 402 is connected to one side of the connecting plate 304;

[0069] By setting the top contact block 402, the top contact block 402 can move with the connecting plate 304. When the connecting plate 304 moves along the limit frame 303 to the preset position, the top contact block 402 set can contact the top contact strip 401. The elastic coefficient of the third spring 310 is greater than the fifth spring 400, the fourth spring 312, the second spring 305, the elastic member 106 and the first spring 201, that is, when the positioning frame 108 has not moved to the extreme position, the damping groove 311 and the damping rod 309 will not be separated. After the top contact block 402 contacts the top contact strip 401, it can press the position of the top contact strip 401, allowing the top contact strip 401 to move downward, so that the supporting bracket 107 can move downward and separate from the probe accessory, thereby achieving the purpose of avoiding the probe accessory and avoiding the problem of the probe accessory being unable to be coaxial with the positioning convex plate 104 due to the existence of the supporting bracket 107.

[0070] As a further solution of the present invention, a second gear 403 is connected to the rotating shaft 300, a second rack 404 adapted to the second gear 403 is connected to one side of the positioning frame 108, a traction shaft 405 is rotatably connected to the traction plate 307, a sixth spring 406 is connected between the traction shaft 405 and the traction plate 307, the elastic coefficient of the sixth spring 406 is greater than the third spring 310, and one end of the traction rope 301 is wound around the traction shaft 405;

[0071] By setting the sixth spring 406, in the initial stage of traction, the sixth spring 406 can limit the position of the traction shaft 405 to prevent its rotation from affecting the traction. When the positioning frame 108 moves to the extreme position and the traction frame 306 slides to the extreme position at the bottom of the connecting plate 304, the rotating shaft 300 continues to rotate, and the traction shaft 405 can be rotated through the traction rope 301 and the sixth spring 406 can generate potential energy. This setting can ensure that after the positioning frame 108, the traction frame 306, and the traction plate 307 move to the extreme position, the rotating shaft 300 can still rotate to provide support for subsequent operations. In addition, the connecting plate 304 allows the supporting bracket 107 to move downward through the top contact block 402 and the top contact strip 401. After the displacement, the top contact block 402 moves to the extreme position on the top contact strip 401. At this time, the position of the connecting plate 304 is restricted, and the second rack 404 can mesh with the second gear 403. The width of the second gear 403 is wider than the second rack 404. The second rack 404 can mesh with the second gear 403 well, and can also ensure that when the probe accessories are at different lengths, the second gear 403 and the second gear 403 can still be in a meshing state. When the rotating shaft 300 continues to rotate, the second rack 404 can be displaced downward by the rotation of the second gear 403, so as to drive the positioning frame 108 to move, thereby achieving the purpose of allowing the positioning frame 108 to avoid the probe accessories.

[0072] As a further solution of the present invention, the moving component also includes a lead screw 500 connected to the rotating shaft 300, a moving frame 501 is threadedly connected to the lead screw 500, an assembly frame 502 slidably connected to the moving frame 501 is slidably connected to the limiting frame 303, a seventh spring 503 is connected between the assembly frame 502 and the assembly housing 100, the assembly frame 502 is connected to the connecting pipe 210, and an eighth spring 504 is connected between the magnet 211 and the assembly bracket 101;

[0073] By setting the eighth spring 504, the eighth spring 504 can use its own potential energy to limit the magnet 211, and when the shaft 300 rotates, the movable frame 501 can be displaced through the lead screw 500. The movable frame 501 can slide on the assembly frame 502 at the initial stage of displacement. After the shaft 300 rotates to move the traction plate 307 to the limit position, the shaft 300 continues to rotate, the traction shaft 405 is rotated by force, and the movable frame 501 moves to the limit position on the assembly frame 502. The positioning frame 108 is separated from the probe accessory by the second gear 403 and the second rack 404, and starts to drive the positioning frame 108 before it moves downward to the limit position. The assembly frame 502 is displaced, driving the connecting tube 210, the positioning plate 103, the positioning convex plate 104, the positioning rod 105 and the probe accessories to move. In the initial stage of movement, the eighth spring 504 is gradually stretched to generate potential energy, and the magnet 211 and the iron rod 212 are still magnetically attracted. When the two probe accessories are initially installed and have not yet been riveted, when the potential energy of the eighth spring 504 is greater than the magnetic connection force, the magnet 211 is reset to its original position by the force of the eighth spring 504, and the iron rod 212 is no longer restricted and moves by the force of the elastic member 106, thereby realizing the automatic release of the probe accessories and using the force of the elastic member 106 to complete the purpose of the last step of the assembly tooling.

[0074] As a further solution of the present invention, a motor 505 is connected to the assembly housing 100, a driving shaft of the motor 505 is connected to one of the rotating shafts 300, and a chain 506 is connected between every two adjacent rotating shafts 300;

[0075] By providing the motor 505 , the motor 505 and the chain 506 can provide driving force for the rotation of the rotating shaft 300 .
