[0002] In order to meet process requirements, when transporting materials, the materials need to be placed on a carrier and moved by driving the carrier. However, in some application fields, such as the photovoltaic field, due to the large size of the materials, the required carrier size is also large.

[0003] Currently, carriers require positioning during the conveying process to ensure accurate conveying and, consequently, machining. Conventional positioning devices typically utilize air flotation. Specifically, an air flotation plate is ventilated to create an air gap between the carrier and the supporting surface, and then a pneumatic cylinder is used to propel the carrier to complete the positioning.

[0004] However, for large-sized vehicles, their mass is relatively heavy, and when using air flotation, large-sized air flotation plates need to be manufactured, resulting in high production costs and large space occupation. Utility Model Content

[0038] Example:

[0039] Figure 1 This is a schematic diagram of the structure of a positioning device for a large-sized carrier provided by an embodiment of the present utility model. Figure 1 As shown, the positioning device includes a conveyor line 1, a positioning component 3 and a plurality of supporting sliding components 2.

[0040] The conveyor line 1 is used to convey the carrier 100 to move along a first direction (X-axis direction).

[0041] Figure 2 This is a schematic diagram of the structure of the supporting sliding assembly provided by the embodiment of the present utility model. Figure 2 As shown, multiple support sliding assemblies 2 are evenly distributed along the circumference in the middle space or peripheral space of the conveyor line 1. Each support sliding assembly 2 includes a first driving member 21, a support portion 22 and an upper slide 23. The upper slide 23 is stacked on the support portion 22. The output end of the first driving member 21 is connected to the support portion 22 to drive the support portion 22 and the upper slide 23 to move in the vertical direction (Z-axis direction) to receive or leave the carrier 100 on the conveyor line 1. The first driving member 21 is, for example, a motor or a cylinder.

[0042] The positioning assembly 3 is used to adjust the position of the carrier 100 at any angle or direction in the horizontal plane after the carrier 100 leaves the conveyor line 1 .

[0043] The contact surface between the upper slide 23 and the carrier 100 is made of non-metallic material to avoid damaging the carrier 100. The friction coefficient between the upper slide 23 and the carrier 100 is large, so that during the positioning and adjustment of the carrier 100, the carrier 100 and the upper slide 23 remain relatively stationary (i.e., they move together).

[0044] In this embodiment, the coefficient of friction between the upper surface of the support portion 22 and the lower surface of the upper slide plate 23 is no greater than 0.3, allowing the carrier to be pushed with a relatively small thrust, thus preventing damage to the internal structure of the carrier 100 due to excessive thrust. During positioning and adjustment of the carrier 100, the upper slide plate 23 moves relative to the support portion 22. In other words, the coefficient of friction between the upper slide plate 23 and the carrier 100 is greater than the coefficient of friction between the upper surface of the support portion 22 and the lower surface of the upper slide plate 23, effectively preventing wear and tear on the carrier 100.

[0045] Furthermore, the upper slide plate 23 and the lower slide plate 223 (the part of the support portion 22 that actually contacts the upper slide plate 23) are not limited to non-metallic materials. Metal materials coated with Teflon or other low-friction materials may also be used. For example, the upper slide plate 23 and the support portion 22 may be made of nylon or PE, allowing the carrier 100 to be pushed with minimal thrust, thereby preventing damage to the internal structure of the carrier 100 from excessive thrust.

[0046] Regarding the positioning device for a large-sized carrier provided by an embodiment of the present invention, when positioning the large-sized carrier 100, first, the conveyor line 1 conveys the carrier 100 from the upstream to above the multiple supporting sliding assemblies 2. Then, the first driving member 21 of the multiple supporting sliding assemblies 2 drives the supporting portion 22 to rise, and when the supporting portion 22 rises, it will also bring the upper slide plate 23 and the carrier 100 to rise synchronously, so that the carrier 100 leaves the conveyor line 1 and is transferred to the multiple supporting sliding assemblies 2. Next, the positioning assembly 3 is used to position and adjust the carrier 100 in the horizontal plane, and in the process of positioning and adjusting the position of the carrier 100, the carrier 100 and the upper slide plate 23 remain relatively stationary (that is, the two move together), and the upper slide plate 23 will move relative to the support portion 22. At this time, it can be ensured that the carrier 100 will not slide relative to the upper slide plate 23 during the movement adjustment process, effectively preventing the problem of carrier 100 being worn. Finally, after the positioning of the carrier 100 is completed, the first driving member 21 drives the support portion 22 and the upper slide plate 23 to move downward, so that the carrier 100 is received back onto the conveyor line 1 and transported downstream through the conveyor line 1 .

[0047] In other words, the present invention provides a positioning device for large-sized carriers, which can easily complete positioning during transportation by using multiple spaced support sliding assemblies 2 in conjunction with the positioning assembly 3. Furthermore, the support sliding assembly 2 has low production costs and occupies little space.

[0048] For example, there may be four supporting sliding components 2. Figure 1 The conveyor line 1 in the example described above is composed of two separate units separated in the second direction (Y-axis direction). In this case, it is preferred that multiple supporting sliding assemblies 2 are evenly distributed along the circumference in the middle space of the conveyor line 1. When the feed conveying mechanism in the conveyor line 1 has other structures, multiple supporting sliding assemblies 2 can also be evenly distributed along the circumference in the outer space of the conveyor line 1 according to actual needs.

[0049] Continue to see Figure 2 The supporting sliding assembly 2 further includes a plurality of springs 24, which are arranged at intervals along the circumference of the upper slide 23, with the ends of each spring 24 connected to the upper slide 23 and the supporting portion 22, respectively. The circumferential arrangement of the plurality of springs 24 on a supporting sliding assembly 2 ensures that the upper slide 23 is subjected to uniform tension.

[0050] In the above embodiment, under the positioning adjustment of the positioning component 3, the carrier 100 and the upper slide 23 will move relative to the support portion 22. After the supporting sliding component 2 removes the carrier 100, the spring 24 can pull the upper slide 23 to automatically return to the initial position, preventing the upper slide 23 from falling from the support portion 22 after multiple movements.

[0051] For example, the number of springs 24 may be three, and in this case, the angle between two adjacent springs 24 is 120°.

[0052] Furthermore, a receiving groove 221 for holding lubricating liquid is provided on one side of the support portion 22 facing the upper slide plate 23. The lubricating liquid in the receiving groove 221 can lubricate the contact surface between the support portion 22 and the upper slide plate 23, reducing friction therebetween and facilitating sliding of the upper slide plate 23 on the support portion 22. The lubricating liquid can be, for example, water or oil.

[0053] For example, the support portion 22 includes a mounting seat 222 and a lower slide 223. The output end of the first driving member 21 is connected to the mounting seat 222, and the lower slide 223 is fixed to the mounting seat 222. The two ends of each spring 24 are respectively connected to the mounting seat 222 and the upper slide 23. The receiving groove 221 is located on the lower slide 223 (see FIG. Figure 3 ).

[0054] Specifically, the positioning device also includes a blocking member 4 and an in-place detection sensor 5, both located at one end of the conveyor line 1, and the output end of the blocking member 4 is used to block and limit the carrier 100 when the carrier 100 moves along the first direction to trigger the in-place detection sensor 5.

[0055] In the above embodiment, the in-position detection sensor 5 can sense when the carrier 100 is transported from the upstream to above the multiple supporting slide assemblies 2, thereby ensuring the accurate stopping position of the carrier 100 and preventing the stopping position of the carrier 100 from exceeding the operating range of the first and second positioning mechanisms. For example, the driving actuator of the blocking member 4 can be a cylinder or a motor. The blocking member 4 is a conventional component that only needs to perform the blocking function. The blocking member 4 is connected to the driving actuator of the blocking member 4 to be driven in operation.

[0056] See also Figure 1 The conveyor line 1 includes two parallel conveyor line units spaced apart, and a plurality of support sliding assemblies 2 are spaced apart between the two conveyor line units. The plurality of support sliding assemblies 2 located between the two conveyor line units can effectively reduce the space occupied by the support sliding assemblies, thereby reducing the space occupied by the positioning device.

[0057] In one implementation of the present invention, each conveyor line unit includes a feed belt line 11 and a discharge linear module alternately distributed in a second direction (Y-axis direction), the second direction is perpendicular to the first direction, the feed belt line 11 is used to drive the carrier 100 to move along the first direction to above the supporting sliding assembly 2, the discharge linear module includes a linear drive mechanism and a supporting member 12 connected to the linear drive mechanism, the supporting member 12 is used to carry the carrier 100 that has completed positioning, and the linear drive mechanism is used to drive the carrier 100 that has completed positioning to continue to move along the first direction to the next workstation.

[0058] Each conveyor line unit also includes a second driving member (not shown), the carrier 12 is connected to the second driving member, the second driving member is connected to the linear drive mechanism, and the second driving member is used to drive the carrier 12 to move in the vertical direction so that the carrier 100 falls on the carrier 12 after the carrier 12 rises.

[0059] Specifically, when positioning the carrier 100, first, the feed belt line 11 transports the carrier 100 from upstream to above the multiple supporting sliding assemblies 2. Then, the first driving member 21 of the multiple supporting sliding assemblies 2 drives the supporting portion 22 to rise, so that the carrier 100 leaves the conveyor line 1. At the same time, the second driving member drives the supporting member 12 to rise. At this time, the height of the supporting member 12 is slightly lower than the supporting height of the supporting sliding assembly 2 (the height difference can be 0.2-0.3mm) to ensure that the carrier 100 is placed on the supporting sliding assembly 2. Then, the positioning assembly 3 adjusts the positioning of the carrier 100 on the horizontal plane. After the adjustment is completed, the first driving member 21 drives the supporting portion 22 to move downward, so that the carrier 100 just falls on the supporting member 12, and the linear drive mechanism drives the second driving member and the supporting member 12 to move along the first direction, and finally transports the carrier 100 to the downstream.

[0060] For example, the carrier 12 can be a carrier plate, with the two feed belt lines 11 positioned between the two discharge linear modules. Preferably, the linear drive mechanism is a linear motor, which offers high positioning accuracy. Of course, other linear drive mechanisms are also possible, such as a screw or synchronous belt drive for less demanding applications.

[0061] In another implementation of the present invention, each conveyor line unit includes a feed belt line 11 and a discharge linear module alternately distributed in a second direction, the second direction is perpendicular to the first direction, the feed belt line 11 is used to drive the carrier 100 to move along the first direction to above the supporting sliding assembly 2, and the discharge linear module includes a linear drive mechanism and a supporting member 12 connected to the linear drive mechanism, the supporting member 12 is used to carry the carrier 100 that has completed positioning, and the linear drive mechanism is used to drive the carrier 100 that has completed positioning to continue to move along the first direction to the next workstation.

[0062] Each conveyor line unit further includes a second driving member, which is connected to the feeding belt line 11 and is used to drive the feeding belt line 11 to move in a vertical direction.

[0063] Specifically, when positioning the carrier 100, first, the second driving member drives the feed belt line 11 to rise, and the feed belt line 11 transports the carrier 100 from the upstream to above the multiple support sliding assemblies 2. Then, the first driving member 21 of the multiple support sliding assemblies 2 drives the support portion 22 to rise, and the second driving member drives the feed belt line 11 to descend, so that the carrier 100 leaves the conveyor line 1 and ensures that the carrier 100 is placed on the support sliding assembly 2, and the feed belt line 11 does not interfere with the subsequent descent of the carrier 100. Then, the positioning assembly 3 adjusts the positioning of the carrier 100 on the horizontal plane. After the adjustment is completed, the first driving member 21 drives the support portion 22 to move downward, so that the carrier 100 falls on the carrier 12, and the linear drive mechanism drives the carrier 12 to move along the first direction, and finally transports the carrier 100 to the downstream.

[0064] That is to say, the second driving member can drive the supporting member 12 to rise and fall, or directly drive the feeding belt line 11 to rise and fall, always ensuring that the carrier 100 is transported from the feeding belt line 11 to the supporting sliding assembly 2 and the supporting member 12 in sequence, and the carrier 100 will not be interfered with during the lifting process.

[0065] For example, the second driving member may be a cylinder or a motor, which is not limited in the present invention.

[0066] The structure of the positioning component 3 is described below:

[0067] In one implementation of the present invention, the positioning assembly 3 includes a first positioning mechanism 31 and a second positioning mechanism 32 separately arranged at both ends of the conveyor line 1 along a first direction, and a third positioning mechanism 33 and a fourth positioning mechanism 34 separately arranged on both sides of the conveyor line 1 along a second direction. The first direction is perpendicular to the second direction. The first positioning mechanism 31 and the second positioning mechanism 32 are used to position and adjust the carrier 100 along the first direction, and the third positioning mechanism 33 and the fourth positioning mechanism 34 are used to position and adjust the carrier 100 along the second direction.

[0068] That is to say, after the carrier 100 is supported and lifted by multiple supporting sliding assemblies 2, the carrier 100 can be positioned in the first direction through the first positioning mechanism 31 and the second positioning mechanism 32, and the carrier 100 can be positioned in the second direction through the third positioning mechanism 33 and the fourth positioning mechanism 34, thereby achieving precise positioning of the carrier 100 in the horizontal direction.

[0069] Specifically, the conveyor line 1 includes at least a discharge linear module, which includes a linear drive mechanism and a carrier 12 connected to the linear drive mechanism. The carrier 12 is used to carry the carrier 100 that has completed positioning, and the linear drive mechanism is used to drive the carrier 100 that has completed positioning to continue moving along the first direction to the next workstation; wherein, the first positioning mechanism 31, the second positioning mechanism 32, the third positioning mechanism 33 and the fourth positioning mechanism 34 are connected to the carrier 12.

[0070] In the above embodiment, after positioning is completed, the carrier 100 falls on the carrier 12, and since the first positioning mechanism 31, the second positioning mechanism 32, the third positioning mechanism 33 and the fourth positioning mechanism 34 are connected to the carrier 12, the positioning of the carrier 100 can always be maintained during the process of transporting the carrier 100 downstream, thereby avoiding the position of the carrier 100 from being offset during the process of transporting it downstream.

[0071] It should be noted that in other embodiments of the present invention, only the first positioning mechanism 31 and the second positioning mechanism 32 are connected to the carrier 12, or the third positioning mechanism 33 and the fourth positioning mechanism 34 are connected to the carrier 12, both of which can maintain the positioning state of the carrier 100 during the downstream transportation process.

[0072] Furthermore, in other embodiments of the present invention, when the carrier 100 is transferred to the carrier 12, positioning pins or increased friction may be used to limit the position between the carrier 100 and the carrier 12. In this case, the first positioning mechanism 31, the second positioning mechanism 32, the third positioning mechanism 33, and the fourth positioning mechanism 34 may not be installed on the carrier 12 and do not move with the carrier 12.

[0073] In this embodiment, the first positioning mechanism 31 close to the inlet end of the conveyor line 1 is located inside the projection of the conveyor line 1 on the horizontal plane.

[0074] It is easy to understand that the first positioning mechanism 31 near the inlet end of the conveyor line 1 is located inside the projection of the conveyor line 1 in the horizontal plane, so that the first positioning mechanism 31 is located below the conveyor line 1 and directly below the carrier 100, so that the card slot 101 (see FIG. 1 ) on the back of the carrier 100 can be directly below the carrier 100. Figure 4 ) or boss for positioning, thereby reducing the space occupied by the first positioning mechanism 31 in the horizontal direction.

[0075] For example, since the carrier 100 is relatively large, the output end of the first positioning mechanism 31 can be directly extended into the card slot 101 on the back of the carrier 100. At this time, the length of the carrier 12 and its supporting structure can be reduced, thereby reducing equipment costs and saving installation space.

[0076] In one implementation of the present invention, the first positioning mechanism 31 and the third positioning mechanism 33 are telescopic cylinders, the second positioning mechanism 32 is a rotary clamping cylinder, for example, the telescopic cylinder is a dedicated blocking cylinder, and the fourth positioning mechanism 34 is a limit block.

[0077] In the above embodiment, after the multiple supporting sliding assemblies 2 support and lift the carrier 100, the piston rod of the telescopic cylinder (i.e., the third positioning mechanism 33) can push the carrier 100 in the second direction, pushing the carrier 100 onto the stop block, thereby completing the positioning of the carrier 100 in the second direction. Furthermore, the piston rod of the other telescopic cylinder (i.e., the first positioning mechanism 31) extends, while the piston rod of the rotary clamping cylinder rotates, then stands upright and moves toward the other telescopic cylinder, ultimately completing the positioning of the carrier 100 in the first direction. When not positioned, the piston rod of the rotary clamping cylinder falls down to avoid interfering with the movement of the carrier 100 in the first direction.

[0078] For example, there may be four limit blocks located on both sides of the conveyor line 1, which can ensure that the feed offset of the carrier 100 is within a controllable range. The number of the first positioning mechanism 31 and the third positioning mechanism 33 may be two.

[0079] It should be noted that in other embodiments of the present invention, at least one of the first positioning mechanism 31, the second positioning mechanism 32, the third positioning mechanism 33 and the fourth positioning mechanism 34 may include a lifting member and a clamping member, and the clamping member is connected to the lifting member. The lifting member can drive the clamping member to rise and fall, and the clamping member can cooperate with other positioning mechanisms to perform horizontal clamping, thereby realizing clamping in the first direction or the second direction.

[0080] In another implementation of the present invention, the positioning component 3 can also be a manipulator and a clamp, the clamp is located on the manipulator, the manipulator drives the clamp to move, and the clamp completes the positioning of the carrier 100, and the present invention does not impose any restrictions on this.

[0081] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
