Abstract
Description
Technical Field
[0001] This invention relates to the field of semiconductor packaging and testing technology, and in particular to a riveting device. Background Technology
[0002] A probe card is a test interface primarily used for testing bare chips. During testing, the probe card connects to the test machine and the chip, transmitting signals to test the chip's parameters.
[0003] When manufacturing probe cards, multiple connectors need to be crimped to the PCB board using a crimping device. Generally, the crimping connection steps are as follows: First, rivets are installed on the connectors, forming a connector module. The connector module is then mounted on the PCB board to form the probe card. At this point, the rivets pass along the axial direction of the PCB board from one end with the connector to the other, forming protrusions. The crimping device sequentially crimps the protrusions of the rivets corresponding to different connector modules, forming flanges to achieve the crimping between the connector and the PCB board.
[0004] However, traditional riveting equipment requires a more complex structure to achieve the riveting connection of multiple connectors to the PCB board. The complex structure of the riveting equipment not only leads to higher manufacturing costs but also requires a larger footprint. Summary of the Invention
[0005] Therefore, it is necessary to address the problem that the complex structure of traditional riveting equipment leads to high manufacturing costs and large footprint, and to provide a riveting device with a simple structure to reduce manufacturing costs and footprint.

[0050] See Figures 1-3One embodiment of this application provides a riveting device 100 for riveting a plurality of connectors 200 to a substrate 400. Optionally, the substrate 400 is a PCB board, and the connectors 200 are connectors with pins. The connectors can be riveted to the PCB board by rivets 300, and the pins of the connectors can be electrically connected to the PCB board. The connectors riveted to the PCB board can form a probe card together with the PCB board. It is conceivable that in some other embodiments, the types of substrate 400 and connectors 200 are not limited, and any substrate 400 and connectors 200 that can be connected by rivets 300 are acceptable.
[0051] Continue reading Figures 1-3 and see Figure 4 The riveting device 100 includes a first module 10 and a second module 20. The first module 10 includes a supporting mechanism 11 and a turntable mechanism 12. The turntable mechanism 12 is disposed on the supporting mechanism 11 and includes a positioning plate 121. The positioning plate 121 has multiple positioning grooves 1211 along the circumference of the turntable mechanism 12. The positioning plate 121 is used to support the substrate 400 and the connector 200. Each positioning groove 1211 is used to insert and position a connector 200. When one end of the rivet 300 is connected to the connector 200, the other end of the rivet 300 passes through the substrate 400 along the thickness direction and forms a protrusion 301 that protrudes from the substrate 400. Both the substrate 400 and the connector 200 can be supported on the positioning plate 121, and at least a portion of the connector 200 can be inserted into the corresponding positioning groove 1211. Thus, when the turntable mechanism 12 drives the substrate 400 and the connector 200 to rotate, under the positioning action of the positioning groove 1211, the substrate 400 and the connector 200 will not be displaced from the turntable mechanism 12, thus ensuring the positioning effect.
[0052] It should be noted that the turntable mechanism 12 can be either a circular or square disc, and no limitation is made here. The circumferential direction of the turntable mechanism 12 is understood as the direction surrounding the outer periphery of the turntable mechanism 12, and the axial direction of the turntable mechanism 12 mentioned in the text is understood as its thickness direction.
[0053] Multiple positioning slots 1211 can be interconnected along the circumferential direction, or they can be set independently. There is no limitation here, as long as they can achieve the effect of positioning the connector 200. Generally, in order to properly position the connector 200, the positioning slots 1211 are conformally adapted to the connector 200.
[0054] Continue reading Figure 4 The second module 20 includes a drive mechanism 21 and a riveting mechanism 22, with the riveting mechanism 22 connected to the drive mechanism 21. The turntable mechanism 12 is operably rotatable circumferentially relative to the support mechanism 11, causing the positioning grooves 1211 to move selectively along the axial direction of the turntable mechanism 12. Figure 1The pressing position (in the Z direction) is opposite to the riveting mechanism 22. Specifically, the turntable mechanism 12 can be driven manually or automatically by a drive structure, which is not limited here.
[0055] Optionally, see Figure 5 The turntable mechanism 12 also includes a turntable assembly 122, with a positioning plate 121 disposed on the turntable assembly 122. The turntable assembly 122 includes a turntable 1221 and an inner ring 1222. The supporting mechanism 11 includes an outer ring 111. The inner ring 1222 is rotatably mounted in the outer ring 111. The turntable 1221 is mounted on the inner ring 1222, and the positioning plate 121 is mounted on the side of the turntable 1221 opposite to the inner ring 1222. Since the inner ring 1222 is rotatably disposed in the outer ring 111, the entire turntable mechanism 12 can rotate relative to the supporting mechanism 11.
[0056] The driving mechanism 21 drives the riveting mechanism 22 to move axially, so that the riveting mechanism 22 presses the rivet 300 on the connector 200 located in the positioning groove 1211 at the pressing position, so as to rivet the connector 200 to the substrate 400 (when the riveting mechanism 22 presses the rivet 300, the rivet 300 is flanged, and the flange can limit the connection between the connector 200 and the substrate 400, thereby realizing the connection and fixation between the connector 200 and the substrate 400). Specifically, when the positioning groove 1211 is opposite to the riveting mechanism 22, the positioning groove 1211 is located below the riveting mechanism 22. In this way, when the rivet 300 is pressed, it is not only subjected to the driving force applied to the riveting mechanism 22 by the driving mechanism 21, but also subjected to the gravity of the riveting mechanism 22. The riveting effect is improved under the combined action of the two forces.
[0057] Optionally, the riveting device 100 also includes a pressure gauge for monitoring the pressing force applied to the rivet 300 by the riveting mechanism 22 to ensure the riveting effect. The riveting mechanism 22 may be made of high-precision alloy steel to ensure structural strength and durability when pressing down on the rivet 300.
[0058] When several connectors 200 need to be riveted to the substrate 400, firstly, one end of the rivet 300 is connected to the connector 200, and the other end of the rivet 300 passes through the substrate 400, forming a protrusion 301 protruding from the other side of the substrate 400. The assembled connectors 200 and substrate 400 are placed on the positioning plate 121, and the connectors 200 are inserted into the positioning groove 1211. At this time, the connectors 200 are also located between the substrate 400 and the positioning plate 121. The turntable mechanism 12 drives the substrate 400 and the connector 200 to rotate circumferentially. When a positioning groove 1211 moves to the pressing position and is directly opposite the riveting mechanism 22, the connector 200 inserted in the positioning groove 1211 is also in the pressing position and directly opposite the riveting mechanism 22. The driving mechanism 21 drives the riveting mechanism 22 to move axially to press the protrusion 301 of the rivet 300 corresponding to the connector 200, thus riveting the connector 200 to the substrate 400. The driving mechanism 21 then drives the riveting mechanism 22 to reset. When the subsequent positioning groove 1211 moves to the pressing position, the riveting mechanism 22 repeats the above action to rivet the subsequent connectors 200 to the substrate 400 until all connectors 200 are riveted to the substrate 400.
[0059] Optionally, each connector 200 is connected to multiple rivets 300. When the riveting mechanism 22 presses, it can simultaneously press multiple rivets 300 connected to the connector 200, thereby riveting the connector 200 to the substrate 400. Of course, in some other embodiments, each connector 200 may also be connected to only one rivet 300. When the riveting mechanism 22 presses, it presses only one rivet 300 connected to the connector 200, thereby riveting the connector 200 to the substrate 400. A washer may also be fitted over the protrusion 301 of the rivet 300. When the rivet 300 is pressed and flipped, it directly contacts the washer, reducing damage to the substrate 400.
[0060] The riveting equipment 100 provided in this application embodiment not only uses the turntable mechanism 12 as a conveying mechanism to transport each connector 200 to the crimping position, but also serves as a support mechanism for the connector 200 when the riveting mechanism 22 crimps the rivet 300. Compared with the prior art (in the prior art, the conveying mechanism transports the substrate 400, and the upper and lower dies of the conveying mechanism cooperate to realize the riveting of the connector 200 and the substrate 400), it is no longer necessary to set up a separate support mechanism to cooperate with the riveting mechanism 22 to realize the riveting of the connector 200 and the substrate 400, which simplifies the structure of the riveting equipment 100, reduces the manufacturing cost of the riveting equipment 100 and reduces the floor space occupied by the riveting equipment 100.
[0061] In some embodiments, see further reference. Figure 1The riveting equipment 100 also includes a frame 30, on which the first module 10 and the second module 20 are both mounted to improve the integration of the riveting equipment 100. In some other embodiments, the frame 30 may be omitted from the riveting equipment 100, and the first module 10 and the second module 20 may be set independently of each other.
[0062] Furthermore, the frame 30 includes a base frame 31 and a gantry frame 32. The gantry frame 32 is mounted above the base frame 31. The first module 10 is mounted on the base frame 31, and the second module 20 is mounted on the gantry frame 32. This allows the second module 20 to be suspended above the first module 10, so that the riveting mechanism 22 can press the rivets 300 on the first module 10 from above.
[0063] The specific structures of the base frame 31 and the gantry frame 32 are not limited here, and can be selected according to specific needs.
[0064] In some embodiments, see further reference. Figure 3 and Figure 5 One of the supporting mechanism 11 and the turntable assembly 122 is provided with a first positioning hole 13, and the other is provided with a first positioning pin 14. The first positioning pin 14 is inserted into the first positioning hole 13 and can rotate circumferentially relative to the first positioning hole 13. In this way, when the turntable mechanism 12 rotates, it always takes the first positioning hole 13 and the first positioning pin 14 as the rotation center, which prevents the turntable mechanism 12 from deviating when rotating and ensures that the riveting mechanism 22 can press the rivet 300.
[0065] The turntable assembly 122 is provided with multiple positioning parts, and the riveting equipment 100 also includes a positioning device mounted on the base frame 31. The positioning device and the multiple positioning parts selectively cooperate with the turntable mechanism 12 to position the positioning groove 1211 to the crimping position. With this configuration, when the turntable mechanism 12 delivers a positioning groove 1211 to the crimping position, the positioning device and the corresponding positioning part of the positioning groove 1211 cooperate to position the positioning groove 1211, avoiding the problem of misalignment between the riveting mechanism 22 and the rivet 300 caused by accidental contact that could cause the turntable mechanism 12 to rotate.
[0066] In some embodiments, see further reference. Figure 4The positioning part includes multiple toothed grooves 15 on the outer peripheral surface of the turntable 1221. The positioning device includes an elastic positioning mechanism 16, which can selectively extend into one toothed groove 15 to restrict the rotation of the positioning turntable mechanism 12. The elastic positioning mechanism 16 can also be compressed and repositioned by the turntable mechanism 12 under its influence. Specifically, when one positioning groove 1211 on the turntable mechanism 12 moves to the pressing position, the elastic positioning mechanism 16 can extend into the toothed groove 15 corresponding to that positioning groove 1211 to position the turntable mechanism 12. When the turntable mechanism 12 rotates, it applies a force to the elastic positioning mechanism 16, causing the elastic positioning mechanism 16 to retract. When another positioning groove 1211 moves to the pressing position, the elastic positioning mechanism 16 extends again into the toothed groove 15 to position the turntable mechanism 12. It can be seen that the elastic positioning mechanism 16 can automatically extend into the tooth groove 15 to position the turntable mechanism 12 under the action of elasticity; and when the turntable mechanism 12 rotates, the elastic positioning mechanism 16 can retract under the action of the force applied by the turntable mechanism 12 due to its elasticity, and will not interfere with the rotation of the turntable mechanism 12.
[0067] Further reading Figure 3 The positioning part includes a plurality of mating holes 17 axially formed in the turntable 1221, the mating holes 17 being eccentrically disposed from the first positioning hole 13 and the first positioning pin 14. The positioning device includes a first positioning mechanism 18, which can selectively extend into the mating hole 17 to position the turntable mechanism 12 or extend out of the mating hole 17 to release the turntable mechanism 12. When a positioning groove 1211 on the positioning plate 121 moves to the pressing position, the first positioning mechanism 18 can extend into the mating hole 17 corresponding to the positioning groove 1211 to restrict the rotation of the turntable mechanism 12. When the turntable mechanism 12 needs to rotate, the first positioning mechanism 18 can retract from the mating hole 17 to release the turntable mechanism 12, thereby avoiding interference with the rotation of the turntable mechanism 12.
[0068] With the above configuration, when the positioning groove 1211 of the turntable mechanism 12 moves to the pressing position, the elastic positioning mechanism 16 extends into the tooth groove 15 to perform coarse positioning (i.e., initial positioning) of the turntable mechanism 12, and the first positioning mechanism 18 extends into the mating hole 17 to perform fine positioning (i.e., secondary positioning) of the turntable mechanism 12, so as to avoid the situation where the force of accidentally touching the turntable mechanism 12 is greater than the elastic force of the elastic positioning mechanism 16, causing the turntable mechanism 12 to rotate.
[0069] It is conceivable that in some other embodiments, the positioning part may only have a toothed groove 15, and the positioning device may only have an elastic positioning mechanism 16, or the positioning part may only have a mating hole 17, and the positioning device may only have a first positioning mechanism 18. It is also conceivable that in some further embodiments, the positioning part and the positioning device may adopt other configurations to achieve the positioning of the turntable mechanism 12, which are not limited here.
[0070] Further reading Figure 3 and Figure 5 The first positioning mechanism 18 includes a second driving member 181 and a positioning rod 182. The positioning rod 182 is connected to the second driving member 181. The second driving member 181 drives the positioning rod 182 to reciprocate axially, so that the positioning rod 182 extends into or out of the mating hole 17. The second driving member 181 can be a cylinder or a motor, etc.
[0071] Because the substrate 400 needs to be riveted to multiple connectors 200, and due to the thickness tolerance of the substrate 400, not all rivets 300 can fully protrude from the surface of the substrate 400 to form protrusions 301. This poses a risk that some rivets 300 of the connectors 200 may be over-pressed or under-pressed, resulting in low reliability of the riveting process. If the substrate 400 is a PCB board and the connector 200 is a connector, improper riveting between the connector and the PCB board can lead to poor contact between the connector pins and the PCB board.
[0072] In some embodiments, see further reference. Figure 1 and Figure 5 The first module 10 also includes a clamping assembly 19 for clamping the substrate 400 onto the positioning plate 121. The clamping assembly 19 includes at least one circumferentially arranged clamping plate 191, which is detachably connected to the positioning plate 121, and the circumferential extension of the clamping assembly 19 covers a plurality of connectors 200. (Continue reading) Figure 2 The clamping plate 191 includes a first clamping part 1911 and a second clamping part 1912. In a first direction, the first clamping part 1911 and the second clamping part 1912 are respectively disposed at opposite ends of the positioning groove 1211. The first direction is the direction of the line connecting the center and the edge of the turntable mechanism 12. When the turntable 1221 is a disc, the first direction is a radial direction of the turntable 1221, i.e. Figure 1 Center Y direction.
[0073] In the above configuration, after the connector 200 is connected to the substrate 400 and supported on the positioning plate 121, the clamping assembly 19 is fixed to the positioning plate 121, and the clamping assembly 19 and the positioning plate 121 cooperate to clamp the substrate 400. Since the circumferential extension length of the clamping assembly 19 covers each corresponding connector 200, and the first clamping part 1911 and the second clamping part 1912 are respectively provided at opposite ends of the connector 200 along the first direction, the clamping assembly 19 can clamp all positions of the substrate 400 connected to the connector 200. Even if the substrate 400 has a large thickness tolerance, the rivets 300 connected to each corresponding connector 200 can fully protrude from the surface of the substrate 400 to form protrusions 301, improving the reliability of the riveting.
[0074] Optionally, the clamping assembly 19 can be fixed to the positioning plate 121 with screws. After all the connecting parts 200 are riveted and fixed to the base plate 400, the clamping assembly 19 can be removed from the positioning plate 121 by unscrewing or loosening the screws, so as to facilitate subsequent work. Of course, in some other embodiments, the clamping assembly 19 can also be detachably connected to the positioning plate 121 in other ways, such as the clamping assembly 19 being snap-fitted to the positioning plate 121.
[0075] In some embodiments, the clamping assembly 19 includes multiple clamping plates 191 that cover all connectors 200 circumferentially. In some specific embodiments, the clamping assembly 19 includes four clamping plates 191 that are joined together to form a complete circular structure around the perimeter.
[0076] In other embodiments, the clamping assembly 19 includes only one clamping plate 191, which covers all connectors 200 circumferentially.
[0077] Further reading Figure 2 The clamping plate 191 also includes a first connecting portion 1913 and a second connecting portion 1914. The first connecting portion 1913, the first clamping portion 1911, the second connecting portion 1914, and the second clamping portion 1912 are connected end to end, and the four together form a clearance position 1915 for avoiding the riveting mechanism 22. Specifically, each clearance position 1915 has a plurality of connecting members 200. The first clamping portion 1911 and the second clamping portion 1912 are connected as one unit through the first connecting portion 1913 and the second connecting portion 1914. Compared with the method in which the first clamping portion 1911 and the second clamping portion 1912 are set independently, the number of parts can be reduced and the loss of parts can be reduced.
[0078] In some embodiments, each connecting part and each clamping part is provided with a threaded hole, and a screw is inserted into the threaded hole to fix the clamping plate 191 and the positioning plate 121.
[0079] In some embodiments, see further reference. Figure 2 To facilitate the installation of the clamping plate 191, the positioning plate 121 is provided with a second positioning pin 1212, and the clamping plate 191 is provided with a second positioning hole 1916. When installing the clamping plate 191, the second positioning pin 1212 passes through the second positioning hole 1916, and then the clamping plate 191 is fixedly connected to the positioning plate 121 by screws. Optionally, the second positioning hole 1916 is a hole with a notch at the end of the clamping plate 191.
[0080] In some embodiments, see further reference. Figure 2 and see Figure 6One of the clamping plate 191 and the riveting mechanism 22 is provided with a guide hole 40, and the other is provided with a guide shaft 50. The guide shaft 50 can be inserted into the guide hole 40 so that the riveting mechanism 22 presses the rivet 300 axially. Specifically, the guide shaft 50 is provided on the riveting mechanism 22, the guide hole 40 is provided on the clamping plate 191, and each positioning groove 1211 is provided with a corresponding guide hole 40.
[0081] The above configuration allows the guide hole 40 and guide shaft 50 to cooperate in guiding the riveting mechanism 22 axially. Furthermore, after the guide shaft 50 is inserted into the guide hole 40, the guide hole 40 can also restrict the position of the guide shaft 50 to restrict the position of the riveting mechanism 22, so that the riveting mechanism 22 can only move axially to press the rivet 300, thus ensuring the riveting effect.
[0082] In some embodiments, see Figure 6 and Figure 7 The driving mechanism 21 includes a first driving member 211, a guide module 212, and a connecting block 213. The connecting block 213 is connected to both the first driving member 211 and the guide module 212, and the riveting mechanism 22 is connected to the connecting block 213. The guide module 212 guides the connecting block 213 axially. Thus, when the first driving member 211 drives the riveting mechanism 22 to move axially via the connecting block 213, the guide module 212 guides the connecting block 213 to prevent it from deviating, thereby preventing the riveting mechanism 22 from deviating and ensuring the final riveting effect.
[0083] Optionally, the first driving component 211 can be a motor, a cylinder, or an electric cylinder, etc.
[0084] In some embodiments, the turntable mechanism 12 includes a plurality of positioning plates 121, one of which is selectively mounted on the turntable assembly 122. There are multiple riveting mechanisms 22, each adapted to one of the positioning plates 121, and one of the riveting mechanisms 22 is selectively mounted on the drive mechanism 21. The multiple positioning plates 121 and the multiple riveting mechanisms 22 can be adapted to the riveting connection between different connectors 200 and the substrate 400. Thus, when riveting different connectors 200 to different substrates 400, a suitable positioning plate 121 and riveting mechanism 22 can be selected.
[0085] In some specific embodiments, there are multiple clamping components 19, each corresponding to a different positioning plate 121. That is, when different positioning plates 121 are selected, the clamping component 19 corresponding to that positioning plate 121 is selected. It is conceivable that in other embodiments, there may be only one clamping component 19, which is adapted to different positioning plates 121.
[0086] Continue reading Figure 6The second module 20 also includes an adjustment mechanism 23, which is mounted on the gantry 32. The drive mechanism 21 is connected to the adjustment mechanism 23. The adjustment mechanism 23 is used to adjust the position of the drive mechanism 21 relative to the turntable mechanism 12 along a first direction, thereby adjusting the position of the riveting mechanism 22 relative to the turntable mechanism 12. This ensures that the riveting mechanism 22 is accurately aligned axially with the connector 200, guaranteeing the riveting effect. Furthermore, by adjusting the position of the riveting mechanism 23 relative to the turntable mechanism 12 along the first direction, the adjustment mechanism 23 can adapt to the riveting requirements of different connectors 200 and different substrates 400.
[0087] Optionally, please continue reading Figure 7 The adjusting mechanism 23 includes a lead screw 231 and a nut 232. The lead screw 231 extends along a first direction, and the nut 232 is screwed onto the lead screw 231. The driving mechanism 21 is connected to the nut 232. Rotation of the lead screw 231 drives the screw rod to move along the first direction, thereby adjusting the position of the driving mechanism 21 relative to the turntable mechanism 12 along the first direction. Specifically, the adjusting mechanism 23 also includes an operating handle 233, which is connected to the lead screw 231. Holding the operating handle 233 facilitates the rotation of the lead screw 231.
[0088] In some embodiments, see further reference. Figure 6 The riveting mechanism 22 includes a connecting module 221, a floating module 222, a push rod 223, and a limiting rod 224. The connecting module 221 is connected to the drive mechanism 21, the floating module 222 is mounted on the connecting module 221, and the push rod 223 and the limiting rod 224 are mounted on the floating module 222. The push rod 223 is used to press the rivet 300, and the limiting rod 224 is used to abut and limit the contact with the base plate 400. The push rod 223 and the limiting rod 224 float axially relative to the connecting module 221 via the floating module 222.
[0089] In the above configuration, when the riveting mechanism 22 presses the rivet 300, the drive mechanism 21 drives the connecting module 221 to move. The connecting module 221 drives the floating module 222, the push rod 223, and the limiting rod 224 to move closer to the turntable mechanism 12. The push rod 223 contacts the rivet 300 and presses it down. When the limiting rod 224 contacts the substrate 400, it indicates that the pressing is in place. The rivet 300 is then flanged to achieve the riveting of the connector 200 and the substrate 400. The floating module 222 ensures that the contact between the push rod 223 and the rivet 300 is soft, preventing the rivet 300 from being damaged by hard contact. At the same time, when the limiting rod 224 contacts the substrate 400, it indicates that the pressing is in place, preventing the push rod 223 from over-pressing the rivet 300 and damaging the substrate 400 and the connector 200.
[0090] See Figure 8The connecting module 221 includes a first connecting plate 2211, a second connecting plate 2212, a third connecting plate 2213, a first adjusting member, and a second adjusting member. The first connecting plate 2211 is connected to the drive mechanism 21, the second connecting plate 2212 is connected to the first connecting plate 2211, the third connecting plate 2213 is connected to the second connecting plate 2212, and the floating module 222 is connected to the third connecting plate 2213. The first adjusting member is used to adjust the position between the first connecting plate 2211 and the second connecting plate 2212 along a first direction, and the second adjusting member is used to adjust the position between the second connecting plate 2212 and the third connecting plate 2213 along a second direction. The first direction and the second direction intersect the axial direction in pairs. Specifically, the first direction and the second direction are perpendicular to the axial direction in pairs. When the first direction is the radial direction of the turntable 1221, the second direction is a direction perpendicular to a radial direction. Figure 1 The X direction is the second direction.
[0091] With the above configuration, when the push rod 223 of the riveting mechanism 22 is not directly aligned with the rivet 300 of the connector 200 located at the crimping position in the axial direction, the adjusting mechanism 23 can coarsely adjust the position of the riveting mechanism 22 in the first direction, and then finely adjust the position between the first connecting plate 2211 and the second connecting plate 2212 in the first direction by the first adjusting member, and finely adjust the position between the second connecting plate 2212 and the third connecting plate 2213 in the second direction by the second adjusting member, so that the push rod 223 is directly aligned with the rivet 300 in the axial direction. Specifically, the central axis of the push rod 223 is directly aligned with the central axis of the rivet 300 in the axial direction to ensure the crimping effect of the crimping rivet 300.
[0092] In some specific embodiments, both the first adjusting member and the second adjusting member include adjusting screws. By turning the adjusting screws, the positions of the first connecting plate 2211 and the second connecting plate 2212 in the first direction can be adjusted, and the positions of the second connecting plate 2212 and the third connecting plate 2213 in the second direction can be adjusted, thereby adjusting the position of the floating module 222 in the first direction and the second direction.
[0093] The connecting module 221 also includes a first crossed roller guide 2214 and a second crossed roller guide 2215. The first crossed roller guide 2214 is disposed between the first connecting plate 2211 and the second connecting plate 2212 to guide the first connecting plate 2211 and the second connecting plate 2212 in a first direction. The second crossed roller guide 2215 is disposed between the second connecting plate 2212 and the third connecting plate 2213 to guide the second connecting plate 2212 and the third connecting plate 2213 in a second direction. The crossed roller guide is a product composed of two guide rails with V-shaped raceways, roller cages, cylindrical rollers, etc. The cylindrical rollers arranged in a crossed manner reciprocate on the precision-ground V-shaped raceway surface, which can withstand loads in various directions and achieve high-precision and stable linear motion.
[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0095] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
