Description

Technical Field

[0001] This utility model relates to the field of probe processing technology, and in particular to a probe copper head riveting device. Background Technology

[0002] After circuit board production, circuits need to be tested using probes. As circuit boards become increasingly sophisticated, probing tiny circuits requires the use of fine metal probes. However, these fine metal probes pose a risk of damaging these delicate circuits. Therefore, copper tips are typically added to the probe ends as probing terminals. Because fine metal probes are easily deformed and difficult to handle, and the corresponding copper tips are also small, the process of fitting and riveting the copper tips together is quite challenging. Current methods generally involve manually fitting the copper tips and then using riveting equipment. This method is inefficient, and manual handling can easily deform the probes during the riveting process. Even with equipment assistance, the small size of the copper tips makes precise alignment difficult, leading to incorrect insertion and failure to connect the probes. Therefore, we need an automated system that can complete the copper tip fitting and riveting process without probe deformation, while ensuring high-efficiency production. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a probe copper head riveting device.

[0004] To achieve the above objectives, a probe copper head riveting device includes a machine base. A circulating transmission mechanism is provided on the machine base. A copper head insertion mechanism, a riveting mechanism, and a material handling mechanism are sequentially arranged at stations along the conveying direction of the circulating transmission mechanism. The copper head insertion mechanism includes a conveying component and a detection component, a scrap removal component, and an insertion component for processing the copper heads on the conveying component. The conveying component includes a positioning seat and a sliding seat that can slide through the positioning seat. The positioning seat has a groove. The sliding seat has a sliding end that matches and extends into the groove and is slidably connected to the groove. The sliding end has a mounting groove parallel to the groove. A mounting block is fixedly fitted in the mounting groove. The sliding end has a placement hole penetrating the body and the mounting block. The sliding seat is connected to a transverse linear module that drives it to move back and forth through the groove.

[0005] By setting up a circulating transmission mechanism to perform cyclic operation on the probes, the mechanism can handle probe feeding and unloading. During the cycle, the copper head is first inserted into the probe via a copper head insertion mechanism. In this process, the insertion mechanism first checks the orientation of the copper head by a detection component. If it is incorrect, the scrap kicking component kicks the copper head out; if it is correct, the insertion component inserts the copper head into the probe. When the probe moves to the next process, the riveting mechanism rivets the probe with the inserted copper head. When the probe continues to move to the next process, the unloading mechanism removes the processed probe. The entire process is automated and highly efficient. The detection component also prevents errors in the orientation of the copper head, ensuring the accuracy of probe insertion. The copper head insertion mechanism also includes a positioning seat and a sliding seat. By setting a storage hole on the sliding seat to accommodate the copper head, the sliding seat drives the copper head back and forth between different processing components, resulting in a high degree of design concentration.

[0006] Preferably, the detection assembly includes a detection seat and a detection cylinder for driving the detection seat to rise and fall. The detection seat is provided with a detection block, and the detection block is provided with a vertically arranged detection through hole. A liftable detection column is matched and provided in the detection through hole. A pin is provided at the upper end of the detection column. A detection sensor is hinged to the detection block. The detection seat is provided with a detection sensor corresponding to one end of the detection sensor. The other end of the detection sensor is provided below the detection through hole. A positioning seat is provided with a pin hole corresponding to the pin. The pin is located on the travel path of the placement hole.

[0007] The detection component cleverly utilizes the lever principle, with one end of the detection sensor pressing against the lower end of the detection column to prevent it from falling. During detection, when the pressure from the copper head is too high, it will cause the other end of the detection sensor to tilt up, triggering the detection sensor to issue an early warning. The advantages of this method are that it is sensitive to triggering, highly accurate, and the lifting pressure is small. When the pin is lifted, it will not cause the copper head to detach from the placement hole, resulting in strong detection stability.

[0008] Preferably, the waste-kicking assembly includes a waste-kicking needle that can move through the top surface of the chute and a waste-kicking cylinder that drives the waste-kicking needle to rise and fall. The waste-kicking needle is located on the travel path of the storage hole, and the positioning seat is provided with a waste-kicking sleeve that extends from top to bottom through the top surface of the chute and matches the waste-kicking needle.

[0009] Preferably, the plug-in assembly includes a plug pin that can move through the top surface of the slide groove and a plug-in cylinder that drives the plug pin to move up and down. The plug pin is located on the travel path of the placement hole, and the positioning seat is provided with a plug-in sleeve that extends from top to bottom through the top surface of the slide groove and matches the plug pin.

[0010] Preferably, the riveting mechanism includes a riveting punch and a riveting cylinder for driving the riveting punch to rise and fall.

[0011] Preferably, the material handling mechanism includes a material handling cylinder clamp and a bidirectional linear module that drives the material handling cylinder clamp to move laterally and move up and down.

[0012] Preferably, the circulating transmission mechanism includes a closed guide groove forming a rectangle, in which multiple movable probe fixtures are placed. Each segment of the closed guide groove is provided with a pusher cylinder to push the probe fixture to the adjacent next segment. The probe fixture includes a probe base and a probe clamping block that fit together. The probe fixture has copper head holes and probe holes that are vertically corresponding and interconnected along the clamping surface of the probe base and the probe clamping block.

[0013] Preferably, the machine base is also provided with a vibratory feeder, the output end of the vibratory feeder outputs to the positioning seat, and the positioning seat is provided with a material discharge hole that connects to the output end of the vibratory feeder and extends vertically through to the chute.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a circulating transmission mechanism to perform cyclical operations on probes. The mechanism allows for probe feeding and unloading. During the cycle, a copper head insertion mechanism first connects the copper head to the probe. The insertion mechanism uses a detection component to check the orientation of the copper head. If incorrect, a scrap kicking component removes the copper head; otherwise, the insertion component connects the copper head to the probe. When the probe moves to the next process, a riveting mechanism rivets the probe with the inserted copper head. As the probe continues to move to the next process, a material handling mechanism retrieves the finished probe. This fully automated cyclical operation is highly efficient. The detection component also prevents errors in the copper head's orientation, ensuring accurate probe insertion. The copper head insertion mechanism also incorporates a positioning seat and a sliding seat. A storage hole on the sliding seat accommodates the copper head, allowing the sliding seat to move the copper head back and forth between different processing components, resulting in a highly integrated design.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] This utility model provides a probe copper head riveting device, such as Figures 1-12 As shown, the machine includes a machine base 100, on which a circulating transmission mechanism 1 is provided. At the workstations in the conveying direction of the circulating transmission mechanism 1, a copper head insertion mechanism 2, a riveting mechanism 3, and a material picking mechanism 4 are sequentially provided. The machine base 100 is also provided with a vibratory feeder 5. The copper head insertion mechanism 2 includes a conveying component 6 and a detection component 7, a waste removal component 8, and an insertion component 9 for processing the copper heads on the conveying component 6.

[0030] The conveying assembly 6 includes a positioning seat 61 and a sliding seat 62 that can slide through the positioning seat 61. The positioning seat 61 has a groove 611. The sliding seat 62 has a sliding end that extends into and is slidably connected to the groove 611. The sliding end has a mounting groove 621 parallel to the groove 611. A mounting block 622 is fixedly fitted into the mounting groove 621. The sliding end has a placement hole 623 that penetrates the body and the mounting block 622. The copper head is placed in the placement hole 623. The sliding seat 62 is connected to a transverse linear module 63 that drives it to move back and forth through the groove 611. The transverse linear module 63 can be implemented using any existing technology. Figure 3 As shown, the transverse linear module 63 includes a transmission bracket 631. A transversely arranged lead screw 632 and a transverse guide rail 633 parallel to the lead screw 632 are mounted on the transmission bracket 631. The lead screw 632 is connected to a lead screw motor 634 that drives its operation. A sliding seat 62 is connected to a fixed seat 635. The lead screw 632 and the transverse guide rail 633 are respectively connected to the fixed seat 635 via matching sliders, thereby driving the fixed seat 635 to move the sliding seat 62 back and forth. The transmission bracket 631 is equipped with a positioning sensor 636, and the fixed seat 635 is equipped with a positioning sensing element 637 corresponding to the positioning sensor 636. This allows the lead screw motor 634 to stop operating when the fixed seat 635 moves to the position corresponding to the positioning sensor 636, achieving precise positioning. The positioning sensor 636 and the positioning sensing element 637 can be implemented using any existing technology.

[0031] The detection assembly 7 includes a detection seat 71 and a detection cylinder 72 that drives the detection seat 71 to rise and fall. A detection block 73 is provided on the detection seat 71. The detection block 73 has a vertically arranged detection through-hole 74. A liftable detection column 75 is matched and disposed within the detection through-hole 74. A pin 76 is provided at the upper end of the detection column 75. A detection sensor 77 is hinged to the detection block 73. A detection sensor 78 corresponding to one end of the detection sensor 77 is provided on the detection seat 71. The other end of the detection sensor 77 is located below the detection through-hole 74. A positioning seat 61 has a pin hole 612 corresponding to the pin 76. The pin 76 is located on the travel path of the placement hole 623. The detection sensor 78 can be implemented using any existing technology. The detection cylinder 72 drives the detection seat 71 to move the detection block 73 up and down. When the detection block 73 rises, since one end of the detection sensor 77 is below the detection through hole 74, the detection sensor 77 supports the detection post 75 to ensure it does not fall. Therefore, the detection post 75 simultaneously drives the ejector pin 76 to rise, detecting the copper head in the ejector pin hole 612. The copper head needs to be riveted to the probe, so the copper head has a structure with one end open and one end closed. When the copper head detected by the ejector pin 76 has the closed end facing downwards, the ejector pin 76 cannot insert into the copper head. At this time, the copper head will drive the detection post 75 to move downwards. The detection post 75 presses down the end of the detection sensor 77. Because the detection sensor 77 is hinged, when the other end of the detection sensor 77 rises to the detection sensor 78, it detects that the copper head is not positioned correctly. Conversely, when the open end of the copper head faces downwards, the ejector pin 76 rises and inserts into the open end, and the copper head will not press down on the detection post 75.

[0032] The waste removal assembly 8 includes a waste removal needle 81 that can move through the top surface of the slide 611 and a waste removal cylinder 82 that drives the waste removal needle 81 to rise and fall. The waste removal needle 81 is located on the travel path of the placement hole 623. The positioning seat 61 is provided with a waste removal sleeve 83 that extends downward through the top surface of the slide 611 and matches the waste removal needle 81. If a copper head is detected as being misplaced, the sliding seat 62 brings the copper head to the corresponding position of the waste removal needle 81, and the waste removal cylinder 82 drives the waste removal needle 81 to press down and push the copper head out of the placement hole 623, thus realizing the waste removal operation.

[0033] The insertion assembly 9 includes an insertion pin 91 that can move through the top surface of the slide groove 611 and an insertion cylinder 92 that drives the insertion pin 91 to rise and fall. The insertion pin 91 is located on the travel path of the placement hole 623. The positioning seat 61 is provided with an insertion sleeve 93 that extends downward through the top surface of the slide groove 611 and matches the insertion pin 91. For a copper head that is accurately positioned, the slide seat 61 brings the copper head to the corresponding position of the insertion pin 91. The insertion cylinder 92 drives the insertion pin 91 to press down and push the copper head out of the placement hole 623, so that it can be sleeved onto the upper end of the probe to realize the insertion operation. It should be noted that in order to ensure the accuracy of the copper head's ejection position, the placement hole 623 matches the copper head, and the copper head has a certain tightness in the placement hole 623 so that the copper head will not fall out even if it leaves the slide groove 611 when there is no external force in the placement hole 623. The insertion assembly 9 also includes a fixed cylinder clamp 94, the output end of which extends below the insertion pin 91 to clamp and position the probe to be processed in the cyclic transmission mechanism 1.

[0034] The riveting mechanism 3 includes a riveting punch 31 and a riveting cylinder 32 that drives the riveting punch 31 to rise and fall.

[0035] The material handling mechanism 4 includes a material handling cylinder clamp 41 and a bidirectional linear module 42 that drives the material handling cylinder clamp 41 to move laterally and move up and down. The material handling mechanism 4 is equipped with a receiving cylinder 43 to facilitate the material handling cylinder clamp 41 in handling and collecting the produced probes. The bidirectional linear module 42 can be implemented using any existing technology, such as... Figure 9 As shown, a horizontally arranged horizontal cylinder 421 and a horizontal guide rail 422 are provided. A horizontal slide block 423 is matched and connected to the horizontal cylinder 421 on the horizontal guide rail 422. A vertically arranged vertical cylinder 424 and a vertical guide rail 425 are provided on the horizontal slide block 423. A vertical slider 426 is provided on the vertical guide rail 425 and connected to the vertical cylinder 424. By fixing the material picking cylinder clamp 41 to the vertical slider 426, bidirectional linear movement can be achieved.

[0036] The circulating transmission mechanism 1 includes a rectangular closed guide groove 11, in which multiple movable probe fixtures 12 are placed. Each segment of the closed guide groove 11 is equipped with a pusher cylinder 13 that pushes the probe fixture 12 to the adjacent next segment. The pusher cylinder 13 pushes the probe fixture 12 to circulate within the closed guide groove 11, sequentially passing through the copper head insertion mechanism 2, the riveting mechanism 3, and the material handling mechanism 4 for cyclic processing. The probe only needs to be placed in the probe fixture 12 before the copper head insertion mechanism 2 using any existing technology. The probe fixture 12 includes a probe base 121 and a probe clamping block 122 that fit together. The probe fixture 12 has corresponding and communicating copper head holes 123 and probe holes 124 along the clamping surfaces of the probe base 121 and the probe clamping block 122. The clamping method allows the probe to be removed by disassembling the probe clamping block 122 if a problem occurs during production. The copper head hole 123 and the probe hole 124 are set up to be corresponding and interconnected. The copper head hole 123 can accommodate part of the copper head to ensure the accuracy of the docking position between the copper head and the probe. In addition, the probe hole 124, which matches the probe, is used to restrict the overall connection during riveting to ensure that the probe body will not be deformed after riveting.

[0037] The output end of the vibratory feeder 5 is connected to the positioning seat 61, and the positioning seat 61 is provided with a discharge hole 613 that is connected to the output end of the vibratory feeder 5 and extends vertically through the slide groove 611. The vibratory feeder 5 can be implemented by any existing method, and how the vibratory feeder 5 conveys the copper head to the discharge hole 613 can also be implemented by any existing technology.

[0038] Working principle: The probe is placed in the probe fixture 12 using any existing technology. The probe fixture 12 is driven by the pusher cylinder 13 to circulate within the closed guide groove 11. The vibratory feeder 5 transports the copper head with one open end to the discharge hole 613. At this time, the sliding seat 62 moves the placement hole 623 to the corresponding position above and below the discharge hole 613 to receive the copper head. The sliding seat 62 then transports the copper head to the corresponding position of the ejector pin 76 of the detection component 7. The detection cylinder 72 drives the ejector pin 76 to move upward to check whether the ejector pin 76 extends into the open end of the copper head. If it is not the open end of the copper head, the detection sensor 77 is triggered to perform a lever movement. The other end of the detection sensor 77 triggers the detection sensor 78, which indicates that the copper head is misplaced. The sliding seat 62 then transports the copper head to the scrap kicking pin 8 of the scrap kicking component 8. At position 1, the kicking cylinder 82 drives the kicking pin 81 downward to push the copper head out of the placement hole 623. Conversely, when the copper head is correctly positioned, the sliding seat 62 transports the copper head to the corresponding position of the insertion pin 91 of the insertion assembly 9. The fixing cylinder clamp 94 clamps and fixes the probe on the probe fixture 12 at this station. The insertion cylinder 92 drives the insertion pin 91 downward to push the copper head out of the placement hole 623 and insert it with the probe end. When the probe fixture 12 transports the inserted probe to the riveting mechanism 3, the riveting cylinder 32 drives the riveting punch 31 to rivet the copper head and the probe. When the probe fixture 12 continues to transport the probe to the material handling mechanism 4, the bidirectional linear module 42 drives the material handling cylinder clamp 41 to take out the processed probe and put it into the storage cylinder 43.
