Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor handling, in particular to a track end face leveling device. Background Art

[0002] In an automatic material handling system (AMHS), tracks are used to connect all devices into an integrated whole. Therefore, the tracks play a very important role. The planning and design of the tracks have a great impact on the operating efficiency of the entire system, and the installation of the tracks is also very important.

[0003] Currently, the traveling tracks of overhead cranes are basically composed of two straight tracks with equal lengths placed in parallel and then fixed together through hard connections (such as hanging brackets). And the entire overhead crane track system is composed of multiple sections of traveling tracks. During assembly, usually, one section of the traveling track is first connected and fixed on the ground, and then the remaining multiple sections of traveling tracks are successively assembled and connected together in the air. To ensure the assembly quality of the overhead crane track system, when assembling one section of the traveling track on the ground, it is necessary to ensure that the end faces of the two parallel straight tracks are in the same vertical plane. Therefore, it is necessary to study a track end face leveling device that is easy to adjust. Summary of the Utility Model

[0004] To overcome the above-mentioned drawbacks, the purpose of the utility model is to provide a track end face leveling device, which can perform end face alignment adjustment on two straight tracks to ensure that the end faces of the two straight tracks are in the same vertical plane.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a track end face leveling device for adjusting the end face positions of multiple straight tracks, and a track chute is provided at the upper end of the straight tracks. The track end face leveling device includes a cooperating adjustment component and a supporting component;

[0006] The supporting components are arranged in one-to-one correspondence with the straight tracks, and the upper ends thereof are used to support the corresponding straight tracks, and rolling bodies are provided at the lower ends;

[0007] The adjustment component includes a reference comparison plate and adjustment parts arranged in one-to-one correspondence with the straight tracks. The reference comparison plate is arranged at one end of the straight track along a direction perpendicular to the straight track, and the side facing the straight track is a comparison plane; the adjustment parts are arranged on the reference comparison plate and are used to drive the comparison plane of the reference comparison plate to fit onto the corresponding straight track.

[0008] During use, place multiple supporting components on the ground (or other placement platforms) with the rolling bodies facing the ground side; place multiple straight rails that require end face alignment adjustment onto the corresponding supporting components in sequence; then install the adjusting parts onto the corresponding straight rails one by one, and make the reference comparison plate located at the same end of the multiple straight rails (the end to be adjusted for end face alignment). Then, drive the comparison plane of the reference comparison plate to fit onto the corresponding straight rail through the operation of the adjusting part until the end faces of all the straight rails are fitted onto the comparison plane.

[0009] Since the end faces of the multiple straight rails are in a misaligned state, during the operation of the adjusting part, the comparison plane will first fit onto the end faces of some straight rails. At this time, it is necessary to continue operating the adjusting part corresponding to this straight rail. Because the comparison plane has already fit onto the end face of this straight rail, when the adjusting part continues to operate, the comparison plane can drive this straight rail to move synchronously (at this time, the rolling bodies roll along the ground) until all the straight rails are fitted onto the comparison plane.

[0010] The beneficial effects of the rail end face leveling device of the present utility model are as follows:

[0011] The straight rails are supported by the supporting components, and rolling bodies are arranged at the lower ends of the supporting components to utilize the rolling friction between the rolling bodies and a smooth plane (such as a tabletop) to reduce the difficulty of moving during the adjustment of the straight rail end faces; in the adjusting component, the comparison plane of the reference comparison plate provides an alignment reference plane for the end faces of the multiple straight rails; and through the arrangement of the adjusting parts, the positions of the corresponding straight rails can be adjusted one by one so that the straight rails can all fit onto the comparison plane, realizing the alignment of the end faces of the multiple straight rails.

[0012] Furthermore, the adjusting part includes a connecting plate, an adjusting member, and a clamping member; the clamping member is arranged on the connecting plate to clamp the corresponding straight rail; the adjusting member is arranged on the reference comparison plate along the direction parallel to the straight rail, and the adjusting member is in threaded connection with the connecting plate. The clamping member is used to clamp the corresponding straight rail to ensure the synchronism of the movement of the straight rail, the clamping member, and the connecting plate during the adjustment process; and through the threaded connection between the adjusting member and the connecting plate, when the adjusting member rotates, it can drive a linear displacement between the reference comparison plate and the connecting plate, thereby realizing the fitting of the reference comparison plate onto the straight rail.

[0013] Furthermore, the adjusting member includes a rod body penetrating through the reference comparison plate. One end of the rod body is coaxially provided with a threaded section for connecting the connecting plate, and the other end is coaxially provided with a pushing section that can abut against the reference comparison plate. When the rod body rotates, the threaded section can be screwed tightly with the connecting plate. On the premise that the position of the connecting plate remains unchanged, the pushing section can drive the reference comparison plate to move towards the direction close to the connecting plate.

[0014] Furthermore, the outer diameters of the pushing section, the rod body, and the threaded section decrease in sequence.

[0015] Furthermore, the pushing section is connected to the torque motor disposed on the reference comparison plate. By setting the torque motor, automatic tightening adjustment of the adjusting member can be achieved.

[0016] Furthermore, the clamping member includes a rotating rod rotatably disposed on the connecting plate, and a clamping block capable of being inserted into the track chute is provided on the rotating rod; when the rotating rod rotates, the clamping block can rotate therewith and press tightly against the two inner side walls of the track chute.

[0017] Furthermore, the clamping block has a strip-shaped structure, and the width of the clamping block is smaller than the notch width of the track chute, so as to facilitate the clamping block to enter the track chute; the length of the clamping block is not less than the distance between the two inner side walls of the track chute, so as to facilitate the clamping block to press tightly against the two inner side walls of the track chute.

[0018] Furthermore, the rotating rod is a screw passing through the connecting plate, and a threaded hole matching the screw is provided on the clamping block. Through the cooperation of the screw and the threaded hole, it is beneficial for a linear displacement to occur between the clamping block and the rotating rod, which is beneficial for clamping the straight rail.

[0019] Furthermore, both side edges of the clamping block in the length direction are composed of continuous straight edges and arc edges, and during the process of the clamping block pressing tightly against the track chute, the arc edge can abut against the inner side wall of the track chute prior to the straight edge.

[0020] By setting the arc edge, it is beneficial to cooperate with the rotation action of the clamping block, rotate the two side edges of the clamping block in the length direction towards the inner side wall of the track chute, and then abut against the inner side wall of the track chute through the straight edge, which can not only use the two straight edges to press tightly against the track chute but also inhibit the continuous rotation of the clamping block.

[0021] Furthermore, the connecting plate includes a connecting cross plate and a connecting vertical plate that are integrally formed and have an L-shaped structure. The clamping member is disposed on the connecting cross plate, and the connecting vertical plate is threadedly connected to the adjusting member; and when the clamping member clamps the straight rail, the connecting cross plate abuts against the upper end surface of the straight rail, and the connecting vertical plate is inserted into the track chute of the straight rail. The connecting vertical plate is defined as being inserted into the track chute of the straight rail to avoid interference of the connecting vertical plate with the fitting of the reference comparison plate to the end surface of the straight rail.

[0022] Furthermore, the supporting assembly includes at least one supporting flat plate, and at least one of the rolling bodies is installed at the lower end of the supporting flat plate. Exemplarily, the rolling body is a freely rotatable bull eye bearing or a universal ball. Description of the Drawings

[0035] The following elaborates on the preferred embodiments of the present utility model in detail with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0036] Embodiment

[0037] See attached Figure 1-2As shown in the figure, a track end face leveling device of the present utility model is used to adjust the end face positions of multiple straight tracks 1, and a track chute 11 is provided at the upper end of the straight track 1. The track end face leveling device includes a cooperating adjustment component 2 and a supporting component 3. Among them, the supporting component 3 is arranged corresponding to each straight track 1, the upper end thereof is used to support the corresponding straight track 1, and a rolling body 31 is provided at the lower end. The adjustment component 2 includes a reference comparison plate 21 and an adjustment part 22 arranged corresponding to each straight track 1. The reference comparison plate 21 is arranged at one end of the straight track 1 along the direction perpendicular to the straight track 1, and the side facing the straight track 1 is a comparison plane 211. The adjustment part 22 is arranged on the reference comparison plate 21 and is used to drive the comparison plane 211 of the reference comparison plate 21 to fit onto the corresponding straight track 1.

[0038] During use, place multiple supporting components 3 on a smooth plane (such as a tabletop), and make the rolling body 31 face the side of the smooth plane; place multiple straight tracks 1 that need to be adjusted for end face alignment on the corresponding supporting components 3 in sequence; then install the adjustment parts 22 onto the corresponding straight tracks 1 one by one, and make the reference comparison plate 21 located at the same end of the multiple straight tracks 1 (the end to be adjusted for end face alignment), and then drive the comparison plane of the reference comparison plate 21 to fit onto the corresponding straight track 1 through the operation of the adjustment part 22; since the end faces of the multiple straight tracks 1 are in a misaligned state, during the operation of the adjustment part 22, the comparison plane 211 will first fit onto the end faces of some straight tracks 1. At this time, it is necessary to continue to operate the adjustment part 22 corresponding to this straight track 1. Because the comparison plane 211 has already fit onto the end face of this straight track 1, when the adjustment part 22 continues to operate, the comparison plane 211 can drive this straight track 1 to move synchronously (at this time, the rolling body 31 rolls along the ground) until the comparison plane 211 fits onto all the straight tracks 1.

[0039] In the end face leveling device, the straight track 1 is supported by the supporting component 3, and a rolling body 31 is provided at the lower end of the supporting component 3 to utilize the rolling friction between the rolling body 31 and a smooth plane (such as a tabletop) to reduce the difficulty of moving during the adjustment of the straight track end face; in the adjustment component 2, the comparison plane 211 of the reference comparison plate 21 provides a reference plane for aligning the end faces of the multiple straight tracks 1; and through the setting of the adjustment part 22, the positions of the corresponding straight tracks can be adjusted one by one so that the straight tracks 1 can all fit onto the comparison plane 211, realizing the alignment of the end faces of the multiple straight tracks 1.

[0040] In some embodiments, as shown in the attached Figure 2-4 As shown in the figure, the adjustment part 22 includes a connecting plate 221, an adjusting member 222, and a clamping member 223; the clamping member 223 is arranged on the connecting plate 221 and is used to clamp the corresponding straight track 1; the adjusting member 222 is arranged on the reference comparison plate 21 along the direction parallel to the straight track 1, and the adjusting member 222 is threadedly connected to the connecting plate 221.

[0041] During adjustment, first, the corresponding straight rail 1 is clamped by the clamping member 223 to ensure the stable connection of the straight rail 1, the clamping member 223, and the connecting plate 221. Then, through the threaded connection between the adjusting member 222 and the connecting plate 221, a linear displacement can be generated between the adjusting member 222 and the connecting plate 221 during the process of screwing the thread, thereby driving the reference comparison plate 21 to move towards the connecting plate 221 to achieve the fitting of the reference comparison plate 21 to the straight rail 1.

[0042] Specifically, as shown in the attached Figure 3 figure, the connecting plate 221 includes a connecting cross plate 2211 and a connecting vertical plate 2212 that are integrally formed and have an L-shaped structure. The clamping member 223 is arranged on the connecting cross plate 2211, and the adjusting member 222 is threadedly connected to the connecting vertical plate 2212. When the clamping member 223 clamps the straight rail 1, the connecting cross plate 2211 abuts against the upper end surface of the straight rail 1, and the connecting vertical plate 2212 is inserted into the track chute 11 of the straight rail 1.

[0043] As shown in the attached Figure 4-6 figure, the clamping member 223 includes a rotating rod 2231 rotatably arranged on the connecting cross plate 2211. The rotating rod 2231 is arranged in the vertical direction, and a clamping block 2232 capable of being inserted into the track chute 11 is provided at its lower end. When the rotating rod 2231 rotates, the clamping block 2232 can rotate accordingly and press tightly against the two inner side walls of the track chute 11.

[0044] It should be noted that the track chute 11 usually adopts a C-shaped groove structure, and the width of the groove opening is smaller than the width between the two inner side walls of the groove. Therefore, in order to enable the clamping block 2232 to smoothly enter the interior of the track chute 11 and press tightly against the two inner side walls of the track chute 11, in some embodiments, as shown in the attached Figure 5 figure, the clamping block 2232 has a long strip structure, and the width of the clamping block 2232 is smaller than the width of the groove opening of the track chute 11. The length of the clamping block 2232 is not less than the distance between the two inner side walls of the track chute 11.

[0045] In the initial state, the width direction of the clamping block 2232 is consistent with the width direction of the track chute 11. At this time, since the width of the clamping block 2232 is smaller than the notch width of the track chute 11, when the clamping block 2232 moves downward toward the track chute 11, the clamping block 2232 can enter the track chute 11 from the notch of the track chute 11; when the connecting cross plate 2211 abuts against the upper end surface of the track chute 11, the clamping block 2232 is located in the track chute 11. At this time, the clamping block 2232 is driven by the rotating rod 2231 to rotate so that the length direction of the clamping block 2232 can be rotated to be consistent with the width direction of the track chute. At this time, since the length of the clamping block 2232 is not less than the distance between the two inner side walls of the track chute 11, both sides of the clamping block 2232 along the length direction can be respectively pressed against the two inner side walls of the track chute 11.

[0046] Furthermore, referring to the attached Figure 6 As shown, the rotating rod 2231 is a screw passing through the connecting cross plate 2211, and a threaded hole for fixedly connecting with the screw is formed on the clamping block 2232. When the clamping block 2232 presses against the two inner side walls of the track chute 11, since the connecting cross plate 2211 is attached to the upper end surface of the track chute 11, as the screw continues to rotate, the clamping block 2232 immediately moves upward and clamps the track chute 11 together with the connecting cross plate 2211. First, the lateral clamping of the track chute 11 is realized by the pressing of the clamping block 2232, and then the vertical clamping of the track chute 11 is realized by the cooperation of the clamping block 2232 and the connecting cross plate 2211. Furthermore, the stable clamping of the straight track 1 is ensured through double clamping.

[0047] Furthermore, referring to the attached Figure 5 As shown, both sides of the clamping block 2232 along the length direction are composed of continuous straight edges 22321 and arc edges 22322, and during the process of the clamping block 2232 pressing against the track chute 11, the arc edges 22322 can abut against the inner side wall of the track chute 11 prior to the straight edges 22321. Through the setting of the arc edges 22322, it is beneficial to cooperate with the rotation action of the clamping block 2232 to smoothly rotate both sides of the clamping block 2232 along the length direction toward the inner side wall of the track chute 11, and then the straight edges 22321 abut against the inner side wall of the track chute 11. In this way, both the two straight edges 22321 can press against the track chute 11 and the continuous rotation of the clamping block 2232 can be inhibited.

[0048] In some embodiments, referring to the attached Figure 4As shown, the adjusting member 222 includes a rod body 2221 passing through the reference control plate 21. One end of the rod body 2221 is coaxially provided with a threaded section 2222 for connecting the connecting vertical plate 2212, and the other end is coaxially provided with a pushing section 2223 that can abut against the reference control plate 21. When the rod body 2221 rotates along the reference control plate 21, the threaded section 2222 can be screwed tightly with the connecting plate 221. On the premise that the position of the connecting plate 221 remains unchanged, the pushing section 2223 can drive the reference control plate 21 to move towards the direction close to the connecting plate 221. Further, the outer diameters of the pushing section 2223, the rod body 2221, and the threaded section 2222 decrease in sequence.

[0049] In some embodiments, the pushing section 2223 is connected to a torque motor 23 disposed on the reference control plate 21 to realize the automatic screwing adjustment of the adjusting member 222. The torque motor 23 can always output force with a constant torque, and even when the reference plane 211 is attached to the straight rail 1, the continuous output of the torque motor 23 will not cause damage to the motor.

[0050] In some embodiments, refer to the appendix Figure 7-8 As shown, the supporting assembly 3 includes at least one supporting flat plate 32, and at least one rolling body 31 is installed at the lower end of the supporting flat plate 32. Further, two supporting flat plates 32 are provided, and one rolling body 31 is provided at each of the four corners at the lower end of each supporting flat plate 32. Exemplarily, the rolling body 31 is a freely rotatable bull's-eye bearing or a universal ball.

[0051] When the straight rail 1 is placed on the supporting flat plate 32, the friction between the straight rail 1 and the supporting flat plate 32 is sliding friction, and the friction between the supporting flat plate 32 and the ground (or other placement platforms) is rolling friction. Since the rolling friction is much smaller than the sliding friction, when the straight rail 1 is pushed by an external force, the straight rail 1 can move relative to the ground together with the supporting flat plate 32.

[0052] Taking the setting of two adjusting parts 22 as an example, the specific working process of this embodiment is as follows:

[0053] 1. Place the two straight rails 1 on the two supporting assemblies 3 respectively: Arrange the two supporting assemblies 3 in parallel, place the two supporting flat plates 32 of the supporting assembly 3 on a smooth plane (such as a tabletop, etc.), and make the rolling bodies 31 contact the tabletop; then place the corresponding straight rail 1 along the length direction on the two supporting flat plates 32;

[0054] 2. Install the adjusting part 22 onto the corresponding straight rail 1 from the upper end of the straight rail 1: Align the clamping block 2232 with the corresponding straight rail 1, and insert the clamping block 2232 into the rail chute 11 from the notch of the rail chute 11 until the connecting cross plate 2211 abuts against the upper end face of the rail chute 11; Adjust the position of the clamping block 2232 in the rail chute 11 so that the connecting vertical plate 2212 is inserted into the rail chute 11, and there is a certain distance between the reference comparison plate 21 and the end face of the straight rail 1; Then rotate the screw so that the clamping block 2232 rotates to tightly press against the two inner side walls of the rail chute 11 to achieve clamping of the straight rail 1 in the horizontal direction; Then continue to rotate the screw, and the clamping block 2232 will immediately move upward and fit against the inner top wall of the rail chute 11. At this time, the clamping block 2232 and the connecting cross plate 2211 jointly clamp the straight rail 1 in the vertical direction;

[0055] 3. Rotate the adjusting member 222 so that the reference comparison plate 21 moves towards the corresponding straight rail 1; Start the torque motor 23 to rotate the adjusting member 222. At this time, the threaded section 2222 will immediately be screwed tightly with the connecting vertical plate 2212. Since the connecting vertical plate 2212 is limited by the straight rail 1, the threaded section 2222 will immediately move towards the straight rail 1, and then the pushing section 2223 can drive the reference comparison plate 21 to move towards the straight rail 1 until the comparison plane 211 fits against the end face of the straight rail 1;

[0056] 4. Align the end faces of the two straight rails 1: When the comparison plane 211 first fits against the end face of one straight rail 1, continue to rotate the adjusting member 222 corresponding to this straight rail 1. At this time, due to the fit between the comparison plane 211 and this straight rail 1, when the reference comparison plate 21 continues to move towards the straight rail, the comparison plane 211 can drive this straight rail 1 to move synchronously, and the rolling body 31 will immediately roll along the ground until the end faces of the two straight rails 1 both fit against the comparison plane 211.

[0057] It should be noted that the original intention of this application is to adjust the alignment operation of the end faces of the two straight rails of the walking track, but this application is also applicable to the alignment operation of the end faces of three or more straight rails, and only the number of adjusting parts needs to be increased accordingly.

[0058] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
