Description

Technical Field

[0001] The present invention relates to the technical field of test probe packaging, in particular to a quantitative packaging machine for test probe production. Background Art

[0002] A test probe is a test connection electronic component used to test PCBAs in electronic testing. The quality of the test probe is mainly reflected in the material, coating, spring, sleeve diameter accuracy and manufacturing process.

[0003] At present, the packaging of test probes is mainly completed by conveyor belts. Specifically, the test probes are carried by the conveyor belt to the top of the packaging box, and then roll into the interior of the packaging box by free fall. The problems with this packaging process are: first, since the test probes are slender structures, they will roll during transportation on the conveyor belt, resulting in the test probes being in a disorderly state when they are transported to the discharge end of the conveyor belt. In this state, the test probes may not be able to fall accurately into the interior of the packaging box; second, the test probes may be bent by impact due to the excessive height of free fall, which has an adverse effect on the yield rate of the test probes.

[0014] The second inclined plate is connected to the first side plate, and a second channel is formed between one end of the second inclined plate and the third side plate.

[0015] Preferably, the buffer drum is arranged obliquely in the conveying direction of the second belt conveyor, and the buffer drum is fixedly connected to the frame of the second belt conveyor through a connecting block.

[0016] Preferably, the first inclined plate is plug-connected to the third side plate, and the other ends of the plurality of first inclined plates are fixedly connected to the same first plate body;

[0017] The second inclined plate is plug-connected to the first side plate, and the other ends of the plurality of second inclined plates are fixedly connected to the same second plate body.

[0018] Preferably, the buffer cylinder is provided with an adjuster, and the adjuster drives the first inclined plate and the second inclined plate to move along their respective inclined directions.

[0019] Preferably, the adjuster includes a threaded rod arranged parallel to the second side plate and a synchronization rod perpendicular to the threaded rod, a first guide rail and a second guide rail fixed at both ends of the synchronization rod, the threaded rod is rotatably connected to the second side plate through a bearing seat, the synchronization rod is threadedly connected to the threaded rod through a nut, the first guide rail and the second guide rail are respectively perpendicular to the plate surfaces of the second plate body and the first plate body, the second plate body and the first plate body are respectively fixed with a first slider and a second slider, the first slider is slidably connected to the first guide rail, and the second slider is slidably connected to the second guide rail.

[0020] Preferably, one end of the threaded rod is fixedly connected to a twisting head.

[0021] Preferably, the buffer cylinder includes an outer metal cylinder and an inner rubber cylinder, and the first inclined plate and the second inclined plate each include an upper rubber plate and a lower metal plate.

[0022] Compared with related technologies, the quantitative packaging machine for test probe production provided by the present invention has the following beneficial effects:

[0023] (1) The present invention sets two adjustment belts and a buffer assembly. On the one hand, the V-shaped groove formed by the two adjustment belts can adjust the axial direction of the probe, so that the axial direction of each probe transported by the second belt conveyor remains consistent. At the same time, since the adjustment belt and the conveyor belt of the second belt conveyor run synchronously, relative friction between the probe and the adjustment belt can be prevented, and the wear of the probe can be reduced while ensuring that the probe can fall accurately into the packaging box per unit time, thereby realizing quantitative packaging of the probe. At the same time, since the adjustment belt and the buffer assembly can buffer the kinetic energy of the falling probe, the bending of the probe due to impact can be effectively avoided, thereby improving the yield rate.

[0024] (2) The present invention shields the falling probe by setting the first inclined plate and the second inclined plate, absorbs the kinetic energy of the probe when it falls, and thus can control the falling speed of the probe, avoid the probe from falling too fast, and achieve buffering of the probe. At the same time, since the first inclined plate and the second inclined plate can form multiple first channels and second channels inside the buffer channel, the first channel and the second channel can only allow one probe to pass through, so the curvature of the probe can be detected. Once the probe is bent and deformed, it cannot pass through the first channel and the second channel, which is beneficial to prevent unqualified products from entering the interior of the packaging box.

[0025] (3) The present invention tilts the buffer cylinder in the conveying direction of the second belt conveyor. As the probe falls, the distance between the probe and the fourth side plate gradually decreases, and the fourth side plate is finally used to align the end of the probe. The structure is simple, ingenious and reasonable.

[0026] (4) In the present invention, since the threaded rod is arranged parallel to the second side plate, the nut threadedly connected to the threaded rod can only move in a direction parallel to the second side plate. Since the first guide rail and the second guide rail are respectively perpendicular to the plate surfaces of the second plate body and the first plate body, the first guide rail can only move in a direction perpendicular to the second plate body, and the second guide rail can only move in a direction perpendicular to the first plate body. Therefore, when the threaded rod is rotated, the nut can drive the first inclined plate and the second inclined plate to move along their respective inclined directions, thereby adjusting the widths of the first channel and the second channel to improve the applicability of the entire buffer assembly without changing the inclination angles of the first plate body and the second plate body.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0046] See also Figures 1 to 9 , an embodiment of the present invention provides a quantitative packaging machine for test probe production, comprising a first belt conveyor 2 and a second belt conveyor 3 for conveying probes 1 and an intermittent conveyor 4 for conveying packaging boxes 5, wherein the conveying direction of the first belt conveyor 2 can be the same as the conveying direction of the second belt conveyor 3, or the conveying direction of the first belt conveyor 2 can also be perpendicular to the conveying direction of the second belt conveyor 3, which is not specifically limited here; the intermittent conveyor 4 is an intermittent conveyor of packaging boxes 5. For example, after the conveying belt of the intermittent conveyor 4 conveys the packaging box 5 to the material receiving position, the conveying belt of the intermittent conveyor 4 stops running. After a certain period of time, when the packaging box 5 is filled with a suitable number of probes 1, the conveying belt of the intermittent conveyor 4 continues to run to send the packaging box 5 away from the material receiving position; the probes 1 on the first belt conveyor 2 fall onto the second belt conveyor 3 by their own gravity. Similarly, the probes 1 on the second belt conveyor 3 also fall into the packaging box 5 on the intermittent conveyor 4 by their own gravity.

[0047] like Figure 1 and Figure 2 As shown, the discharge end of the first belt conveyor 2 is located above the feed end of the second belt conveyor 3 to receive the probe 1 conveyed by the first belt conveyor 2 .

[0048] like Figure 1 and Figure 3 As shown, two adjusting belts 301 are fixedly connected to the conveying belt of the second belt conveyor 3. The two adjusting belts 301 are symmetrically arranged and form a V-shaped groove 302 on the top of the second belt conveyor 3. The adjusting belts 301 can be made of rubber material or the same material as the conveying belt of the second belt conveyor 3. The specific structure of the adjusting belts 301 is as follows: Figure 1As shown, it can move together with the conveyor belt of the second belt conveyor 3, so as to avoid friction between the probe 1 and the adjustment belt 301, thereby ensuring that the probe 1 can accurately enter the interior of the buffer assembly at a certain interval. For example, due to the synchronous movement between the probe 1 and the adjustment belt 301, the probe 1 can move together with the conveyor belt of the second belt conveyor 3 without pausing due to friction with the adjustment belt 301. Since the packaging box 5 is transported by the intermittent conveyor 4, the problem of the probe 1 pausing on the second belt conveyor 3 is solved, and it can be ensured that the required number of probes 1 can be received in the packaging box 5 during the pause time, thereby realizing the quantitative packaging operation of the probe 1.

[0049] The V-groove 302 formed by the two adjustment belts 301 has the function of adjusting the direction of the probe 1. Specifically, the probe 1 dropped from the first belt conveyor 2 will first contact the two adjustment belts 301. Since the V-groove 302 is formed between the two adjustment belts 301, no matter how much the angle between the axial direction of the probe 1 and the conveying direction of the second belt conveyor 3 is before the probe 1 contacts the adjustment belt 301, after the probe 1 contacts the adjustment belt 301, the axial direction of the probe 1 will be adjusted to the same state as the conveying direction of the second belt conveyor 3. At the same time, the two adjustment belts 301 will also limit the axial direction of the probe 1 to prevent the probe 1 from rolling on the conveying belt of the second belt conveyor 3, and keep the axial direction of the probe 1 in the same state as the conveying direction of the second belt conveyor 3 until the probe 1 enters the interior of the buffer assembly. The two adjustment belts 301 have a simple structure and low cost of use and maintenance.

[0050] The specific reason why the axial direction of the probe 1 is adjusted to the same state as the conveying direction of the second belt conveyor 3 is that after the probe 1 falls, its two axial ends will contact the two adjustment belts 301 at the same time or at different times. At this time, the adjustment belt 301 will absorb the kinetic energy of the falling probe 1 to prevent the probe 1 from being injured. On the other hand, the cooperation of the two inclined surfaces of the V-groove 302 will cause the probe 1 to gradually roll to the bottom of the V-groove 302. When the probe 1 rolls, the axial direction of the probe 1 will gradually be adjusted to the same state as the conveying direction of the second belt conveyor 3.

[0051] The discharge end of the second belt conveyor 3 is located above the intermittent conveyor 4 so as to receive the probe 1 conveyed by the second belt conveyor 3 using a packing box 5;

[0052] A buffer assembly for buffering the falling probe 1 is provided between the discharge end of the second belt conveyor 3 and the packaging box 5 .

[0053] By setting up two adjustment belts 301 and a buffer assembly, on the one hand, the V-groove 302 formed by the two adjustment belts 301 can adjust the axial direction of the probe 1, so that the axial direction of each probe 1 transported by the second belt conveyor 3 remains consistent. At the same time, since the adjustment belt 301 and the conveyor belt of the second belt conveyor 3 run synchronously, relative friction between the probe 1 and the adjustment belt 301 can be prevented, thereby reducing the wear of the probe 1 and ensuring that the probe 1 can accurately fall into the packaging box 5 per unit time, thereby realizing quantitative packaging of the probe 1. At the same time, since the adjustment belt 301 and the buffer assembly can buffer the kinetic energy of the falling probe 1, the bending of the probe 1 due to impact can be effectively avoided, thereby improving the yield rate.

[0054] like Figures 4 to 9 As shown, the buffer assembly includes a buffer cylinder 61, a plurality of first inclined plates 62 and a plurality of second inclined plates 63. The interior of the buffer cylinder 61 is provided with a buffer channel 615 with openings at both ends. When in use, the probe 1 enters the interior of the buffer channel 615 from the opening at the top of the buffer channel 615, and is then discharged from the buffer channel 615 through the opening at the bottom of the buffer channel 615. The first inclined plate 62 and the second inclined plate 63 are respectively arranged on two opposite sides of the inner wall of the buffer channel 615, so that the buffer channel 615 is Z-shaped. The Z-shaped channel can effectively buffer the probe 1 to prevent the probe 1 from being damaged or bent due to excessive drop.

[0055] Further, such as Figures 4 to 9 As shown, the buffer cylinder 61 includes a first side plate 611, a second side plate 612, a third side plate 613 and a fourth side plate 614. The first side plate 611 and the third side plate 613 are parallel to each other, and the second side plate 612 and the fourth side plate 614 are parallel to each other. In this embodiment, the first side plate 611 and the second side plate 612 are perpendicular to each other, that is, the buffer cylinder 61 is a square cylindrical structure; the buffer channel 615 is formed by the first side plate 611, the second side plate 612, the third side plate 613 and the fourth side plate 614; the first inclined plate 62 is connected to the third side plate 613, and a first channel 621 is formed between one end of the first inclined plate 62 and the first side plate 611; the second inclined plate 63 is connected to the first side plate 611, and a second channel 631 is formed between one end of the second inclined plate 63 and the third side plate 613.

[0056] The first inclined plate 62 and the second inclined plate 63 are provided to block the falling probe 1 and absorb the kinetic energy of the probe 1 when it falls, so that the falling speed of the probe 1 can be controlled to prevent the probe 1 from falling too fast, thereby buffering the probe 1. At the same time, since the first inclined plate 62 and the second inclined plate 63 can form multiple first channels 621 and second channels 631 inside the buffer channel 615, the first channel 621 and the second channel 631 can only allow one probe 1 to pass through, the curvature of the probe 1 can be detected. Once the probe 1 is bent and deformed, it cannot pass through the first channel 621 and the second channel 631, which is beneficial to prevent unqualified products from entering the interior of the packaging box 5.

[0057] Further, such as Figure 2 As shown, the buffer drum 61 is arranged obliquely in the conveying direction of the second belt conveyor 3 , and the buffer drum 61 is fixedly connected to the frame 303 of the second belt conveyor 3 through a connecting block 616 .

[0058] By tilting the buffer cylinder 61 in the conveying direction of the second belt conveyor 3 , the distance between the probe 1 and the fourth side plate 614 will gradually decrease during the falling process of the probe 1 , and the fourth side plate 614 will eventually complete the alignment of the end of the probe 1 .

[0059] The specific installation method of the first inclined plate 62 and the second inclined plate 63 is as follows.

[0060] like Figure 4 、 Figure 5 、 Figure 7 and Figure 9 As shown, the first inclined plate 62 is plugged into the third side plate 613, and the other ends of several first inclined plates 62 are fixedly connected to the same first plate body 622, and one first plate body 622 can drive multiple first inclined plates 62 to move synchronously; the second inclined plate 63 is plugged into the first side plate 611, and the other ends of several second inclined plates 63 are fixedly connected to the same second plate body 632, and one second plate body 632 can drive multiple second inclined plates 63 to move synchronously, thereby facilitating the adjustment of the width of the first channel 621 and the second channel 631.

[0061] The specific adjustment process of the first plate 622 and the second plate 632 is as follows.

[0062] An adjuster is provided on the buffer cylinder 61, which drives the first inclined plate 62 and the second inclined plate 63 to move along their respective inclined directions. Specifically, the adjuster includes a threaded rod 71 arranged parallel to the second side plate 612 and a synchronization rod 72 perpendicular to the threaded rod 71, a first guide rail 74 and a second guide rail 76 fixed at both ends of the synchronization rod 72, the threaded rod 71 is rotatably connected to the second side plate 612 through a bearing seat 73, and the synchronization rod 72 is threadedly connected to the threaded rod 71 through a nut 721, the first guide rail 74 and the second guide rail 76 are respectively perpendicular to the plate surfaces of the second plate body 632 and the first plate body 622, and a first slider 75 and a second slider 77 are fixed on the second plate body 632 and the first plate body 622, respectively. The first slider 75 is slidably connected to the first guide rail 74, and the second slider 77 is slidably connected to the second guide rail 76.

[0063] Since the threaded rod 71 is arranged parallel to the second side plate 612, the nut 721 threadedly connected to the threaded rod 71 can only move in a direction parallel to the second side plate 612. Since the first guide rail 74 and the second guide rail 76 are perpendicular to the plate surfaces of the second plate body 632 and the first plate body 622 respectively, the first guide rail 74 can only move in a direction perpendicular to the second plate body 632, and the second guide rail 76 can only move in a direction perpendicular to the first plate body 622. Therefore, when the threaded rod 71 is rotated, the nut 721 can drive the first inclined plate 62 and the second inclined plate 63 to move along their respective inclined directions, thereby adjusting the width of the first channel 621 and the second channel 631 to improve the applicability of the entire buffer assembly, and it is also possible not to change the inclination angle of the first plate body 622 and the second plate body 632.

[0064] One end of the threaded rod 71 is fixedly connected to a twisting head 711 . The twisting head 711 may be in the shape of a hexagonal column. When in use, a hexagonal sleeve may be put on the twisting head 711 to facilitate the user in twisting the threaded rod 71 .

[0065] The buffer cylinder 61 includes an outer metal cylinder and an inner rubber cylinder, and the first inclined plate 62 and the second inclined plate 63 both include an upper rubber plate and a lower metal plate. This can further improve the protection of the probe 1 so that it only contacts the inner rubber cylinder and the upper rubber plate made of rubber during the entire falling process.

[0066] The working principle of the quantitative packaging machine for test probe production provided by the present invention is as follows: when in use, the first belt conveyor 2, the second belt conveyor 3 and the intermittent conveyor 4 are started, the first belt conveyor 2 conveys the probes 1 to the second belt conveyor 3, the intermittent conveyor 4 conveys the packaging box 5 to the bottom of the buffer cylinder 61 and then stops, the second belt conveyor 3 conveys the adjusted probes 1 to the inside of the buffer cylinder 61, and finally the buffer cylinder 61 conveys the probes 1 to the inside of the packaging box 5. After the packaging box 5 is loaded with a suitable number of probes 1, the intermittent conveyor 4 is restarted, the packaging box 5 with the probes 1 is removed from the bottom of the buffer cylinder 61, and the packaging box 5 without the probes 1 is conveyed to the bottom of the buffer cylinder 61;

[0067] The adjustment principle of the probe 1 by the second belt conveyor 3 is as follows: the axial ends of the probe 1 dropped from the first belt conveyor 2 will contact the inclined surfaces of the two adjustment belts 301 simultaneously or at different times. At this time, the adjustment belt 301 will absorb the kinetic energy of the probe 1 falling to prevent the probe 1 from being damaged. On the other hand, the two inclined surfaces of the V-shaped groove 302 will cooperate to cause the probe 1 to gradually roll to the bottom of the V-shaped groove 302. As the probe 1 rolls, the axial direction of the probe 1 will gradually be adjusted to the same state as the conveying direction of the second belt conveyor 3, thereby completing the adjustment of the axial direction of the probe 1.

[0068] Afterwards, the probe 1 and the adjustment belt 301 move together with the conveyor belt of the second belt conveyor 3. During this process, on the one hand, friction between the probe 1 and the adjustment belt 301 can be avoided. On the other hand, the two adjustment belts 301 can be used to limit the direction of the probe 1, so that the axial direction of the probe 1 always remains in the same state as the conveying direction of the conveyor belt of the second belt conveyor 3.

[0069] The probe 1 then passes from the second belt conveyor 3 into the buffer cylinder 61. The first inclined plate 62 and the second inclined plate 63 inside the buffer cylinder 61 buffer and absorb the kinetic energy of the probe 1 during its fall, allowing the probe 1 to pass through the buffer cylinder 61 at a low speed and eventually fall into the packaging box 5.

[0070] During the process of the probe 1 passing through the first channel 621 and the second channel 631, since the first channel 621 and the second channel 631 can only accommodate one probe 1, the curvature of the probe 1 can be detected. Once the probe 1 is bent and deformed, it cannot pass through the first channel 621 and the second channel 631, which helps prevent unqualified products from entering the packaging box 5. If the unqualified probe 1 is stuck at a position in the first channel 621 or the second channel 631, the staff can remove it immediately.

[0071] When it is necessary to adjust the width of the first channel 621 and the second channel 631 according to the size of the probe 1, the threaded rod 71 is directly screwed by the screw head 711 to drive the nut 721 to move axially along the threaded rod 71. Since the threaded rod 71 is arranged parallel to the second side plate 612, the nut 721 threadedly connected to the threaded rod 71 can only move in a direction parallel to the second side plate 612. Since the first guide rail 74 and the second guide rail 76 are perpendicular to the plate surfaces of the second plate body 632 and the first plate body 622 respectively, the first guide rail 74 can only move in a direction perpendicular to the second plate body 632, and the second guide rail 76 can only move in a direction perpendicular to the first plate body 622. Therefore, when the nut 721 moves up, the first guide rail 74 and the second guide rail 76 are both When the nut 721 is moved downward, the first guide rail 74 and the second guide rail 76 will move downward, and the first guide rail 74 and the second guide rail 76 will push the first slider 75 and the second slider 77 to move closer, respectively, that is, the width of the first channel 621 and the second channel 631 will gradually decrease, and the inclination angle of the first plate 622 and the second plate 632 will not be changed during the entire adjustment process. The setting of the adjuster can realize the synchronous adjustment of the first inclined plate 62 and the second inclined plate 63, and the overall consistency is good, and the width of the first channel 621 and the second channel 631 will not be inconsistent.

[0072] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0073] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
