Description

Technical Field

[0001] The invention relates to the field of conveying equipment, and in particular to a conveying equipment for heavy tooling plates. Background Art

[0002] In modern industrial production, conveying equipment is widely used in various production lines, material handling, assembly and testing, especially in mechanical processing, electronic assembly and automated production. As the manufacturing industry continues to increase its requirements for production accuracy, conveying equipment plays a vital role in improving work efficiency, precise positioning and reducing manual intervention. Therefore, conveying equipment needs to have higher stability and stronger carrying capacity to cope with increasingly complex workloads and production needs.

[0003] In the current market, the combination of linear guides and sliding components is usually used to switch the workpiece between the upper and lower positions during the conveying process of the assembly line. Specifically, the conveying mechanism is generally composed of multiple linear guides, sliding components, guide wheels, material bearing parts, etc. These components achieve smooth lifting and lowering through precise matching. In the common design, the sliding component consists of a slide and a guide wheel. The guide wheel cooperates with the linear guide. The slide moves on the guide rail through the action of the driving mechanism to achieve the lifting and lowering of materials such as tooling plates. In order to improve the carrying capacity and stability, many conveying equipment adopts two sets of conveying mechanisms arranged symmetrically to ensure that the material or workpiece remains stable during the lifting process.

[0004] However, existing conveying equipment often faces stability issues when the load is heavy or the tooling plate is not completely centered. In particular, when the tooling plate is heavy (for example, more than one ton) and is not centered, the uneven load in the conveying system will cause unstable gear meshing in the transmission system, and even gear slippage or jump. This unstable gear meshing will cause uneven load distribution on both sides of the conveying mechanism, causing the tooling plate to tilt during the lifting process, such as Figure 5 As shown, the contact between the guide wheel and the guide rail is uneven, which in turn generates excessive friction. These factors work together to cause the guide wheel to get stuck or even jammed, seriously affecting the smooth progress of the lifting process. Especially after the tooling board is stuck, complex maintenance operations must be performed to restore normal operation. However, due to the heavy weight of the tooling board (for example, more than one ton), maintenance personnel need to use equipment such as cranes or forklifts to remove the tooling board and adjust the position of the guide wheel. This maintenance process is not only cumbersome and time-consuming, but also increases production downtime, seriously affecting production efficiency. Therefore, when existing conveying equipment handles large loads, especially when the guide wheel is stuck, the maintenance work is very complicated and inconvenient. Summary of the invention

[0005] The purpose of the present invention is to provide a conveying equipment which optimizes the matching design of guide wheels and guide rails so that the conveying equipment can still be lifted and lowered smoothly when the load is large or the tooling plate is not completely centered, effectively avoiding the phenomenon of the guide wheels and guide rails getting stuck or jammed during the lifting of the tooling plate, thereby simplifying the equipment maintenance process.

[0054] Figure 1 is a schematic structural diagram of a conveying device in one embodiment of the present invention, Figure 2 is a schematic front cross-sectional view of a conveying device in one embodiment of the present invention, Figure 3 is a schematic structural diagram of an annular guide rail in one embodiment of the present invention, Figure 4 It is a schematic structural diagram of a sliding assembly and a linear guide rail in a state of cooperative connection in one embodiment of the present invention.

[0055] like Figure 1 , Figure 2 and Figure 4 As shown, a preferred embodiment of the present application provides a conveying device for lifting and transferring heavy-weight tooling plates 600, wherein the dead weight of the heavy-weight tooling plates 600 is mostly more than 1 ton, which is much heavier than the common tooling plates 600. Therefore, if a traditional lifting device is used to transfer the heavy-weight tooling plates 600, it will cause many problems. Therefore, the present application proposes a conveying device for transferring heavy-weight tooling plates 600.

[0056] A conveying device for transporting a heavy tooling plate 600 includes a frame 100, two sets of lifting mechanisms 200, a material receiving member 300 and a driving mechanism 400, wherein the two sets of lifting mechanisms 200 are both arranged in the frame 100, the two sets of lifting mechanisms 200 are arranged in a mirror image, each set of lifting mechanisms 200 includes at least one lifting assembly 210, the lifting assembly 210 includes a linear guide rail 2111 and a sliding assembly 212, the linear guide rail 2111 is arranged in the frame 100, and the linear guide rail 2111 is arranged perpendicular to the horizontal plane, and the sliding assembly 212 includes a slide seat 2121 and a guide seat 2122. Wheel 2122, guide wheel 2122 is rotatably connected with slide 2121, the number of guide wheels 2122 in a sliding assembly 212 is four, each guide wheel 2122 is arranged in parallel, and every two guide wheels 2122 form a group, two groups of guide wheels 2122 are arranged on the same side of slide 2121, and the two groups of guide wheels 2122 are respectively located on the two sides of the linear guide 2111 facing each other, and the linear guide 2111 is clamped between the two groups of guide wheels 2122, so that when the tooling plate 600 is raised or lowered, the lateral support of the tooling plate 600 is realized through the cooperation of the guide wheel 2122 and the linear guide 2111. The material receiving member 300 is connected to the slide 2121 to move with the slide 2121. The material receiving member 300 includes a material receiving surface 310. The material receiving surface 310 and the material receiving surface 310 mirrored therewith form a material placement surface to receive the tooling plate 600. The material placement surface is arranged between two mirrored linear guide rails 2111. The driving mechanism 400 includes a driving member 410. The driving member 410 moves in a controlled manner. The driving member 410 is connected to the slide 2121 to drive the sliding assembly 212 to move along the linear guide rail 2111.

[0057] Conventional lifting devices for medium and low weight tooling boards 600 often face stability problems when the load is heavy or the tooling board 600 is not completely centered. In particular, when the tooling board 600 weighs more than one ton and is not centered, the uneven load in the lifting system will cause the gear meshing in the transmission system to be unstable, causing the gears to slip or jump, resulting in uneven load distribution on both sides of the lifting mechanism 200, causing the tooling board 600 to tilt during the lifting process, such as Figure 5 As shown, this results in uneven contact between the guide wheel 2122 and the linear guide rail 2111, resulting in excessive friction. Under the combined effect of these factors, the guide wheel 2122 may become stuck or even jammed, seriously affecting the smooth progress of the lifting process.

[0058] In order to avoid the problem of the guide wheels 2122 getting stuck or stuck during the lifting and lowering of the tooling plate 600, the relative positions of the four guide wheels 2122 in the sliding assembly 212 and the matching relationship between the guide wheels 2122 and the linear guide rail 2111 are redesigned in this embodiment. The line connecting the centers of two guide wheels 2122 in one group of guide wheels 2122 is arranged in parallel with the line connecting the centers of two guide wheels 2122 in another group, and the perpendicular bisector of the line connecting the centers of the two guide wheels 2122 in one group is collinear with the perpendicular bisector of the line connecting the centers of the two guide wheels 2122 in another group, and the two guide wheels 2122 in one group are located between the two guide wheels 2122 in another group. When the two guide wheels 2122 in one group are both in contact with one side of the linear guide rail 2111, the circumferential sides of the two guide wheels 2122 in the other group are left with a preset gap a with the other side of the linear guide rail 2111, such as Figure 4 As shown, the preset gap a is a key factor in preventing the guide wheel 2122 from getting stuck or jammed during the lifting and lowering of the tooling plate 600. The preset gap a is configured so that when the tooling plate 600 is placed on the material loading surface and the driving member 410 drives the slide 2121 to move, the force applied to the guide wheel 2122 by the slide 2121 is greater than the maximum friction force exerted on the guide wheel 2122, so that the guide wheel 2122 moves along the linear guide rail 2111.

[0059] In order to avoid jamming or blocking between the guide wheel 2122 and the linear guide rail 2111 during the lifting process, the relative positions of the four guide wheels 2122 in the sliding assembly 212 and the matching relationship between the guide wheel 2122 and the linear guide rail 2111 are redesigned in this embodiment. The specific design points are as follows:

[0060] The parallel and collinear arrangement of the guide wheels 2122 is designed such that the line connecting the centers of the two guide wheels 2122 in one of the two groups of guide wheels 2122 is arranged in parallel with the line connecting the centers of the two guide wheels 2122 in the other group, and the perpendicular bisector of the line connecting the centers of the two guide wheels 2122 in one group is collinear with the perpendicular bisector of the line connecting the centers of the two guide wheels 2122 in the other group. Such an arrangement ensures the symmetry and precise alignment of the two groups of guide wheels 2122 in relative position. In this way, the uneven contact between the guide wheels 2122 and the linear guide rail 2111 due to the position deviation of the guide wheels 2122 is avoided, thereby reducing the risk of jamming or blocking caused by uneven friction.

[0061] The guide wheels 2122 are located on the same side and form a preset gap a. The two groups of guide wheels 2122 are respectively located on the opposite sides of the linear guide rail 2111. In order to ensure the smooth operation of the guide wheels 2122, when the two guide wheels 2122 in one group are in contact with one side of the linear guide rail 2111, a preset gap a is left between the two guide wheels 2122 in the other group and the other side of the linear guide rail 2111. This preset gap a ensures that a certain amount of movable space is always maintained between the guide wheels 2122 and the linear guide rail 2111, avoiding the guide wheels 2122 from getting stuck due to assembly errors or uneven loads. By maintaining a suitable gap, interference between the guide wheels 2122 is avoided when the load is uneven or the tooling plate 600 is not placed in the center.

[0062] One of the key points of the design is the configuration of the preset gap a. When the tooling plate 600 is placed on the material placement surface and the driving member 410 drives the slide 2121 to move along the linear guide rail 2111, the force applied by the slide 2121 to the guide wheel 2122 will be greater than the maximum friction force on the guide wheel 2122. In other words, the force applied by the slide 2121 is sufficient to enable the guide wheel 2122 to overcome the friction force and move smoothly along the linear guide rail 2111. Through this configuration, it is ensured that the guide wheel 2122 will not get stuck or lose the ability to run smoothly due to excessive friction, thereby avoiding the occurrence of jamming or jamming.

[0063] Therefore, by maintaining the matching relationship between the preset gap a and the force, the system can effectively avoid the lifting failure caused by the guide wheel 2122 getting stuck under heavy load, thereby improving the stability and reliability of the equipment, and even if the tooling plate 600 is heavy or unevenly placed, the lifting process can still proceed smoothly. It also further simplifies the maintenance work. This design can effectively avoid the situation where the guide wheel 2122 is stuck and requires tedious maintenance, reduces the difficulty of maintenance and production downtime after equipment failure, and thus improves production efficiency.

[0064] In summary, this embodiment redesigns the relative positions of the four guide wheels 2122 in the sliding assembly 212 and the matching relationship between the guide wheels 2122 and the linear guide rail 2111. By optimizing the matching relationship between the guide wheels 2122 and the linear guide rail 2111 and reasonably configuring the preset gap a, it is achieved to avoid the guide wheels 2122 from getting stuck or stuck during the lifting process, improve the stability and reliability of the equipment, and reduce the maintenance workload and production downtime. It can be understood that the specific value of the preset gap a can be obtained through repeated tests. For example, when the weight of the tooling plate 600 is 1 ton, it can be obtained through experiments that the preset gap a can take any value between 1.25mm and 1.75mm to avoid the guide wheels 2122 from getting stuck or stuck. Specifically, the preset gap a of 1.5mm is the best.

[0065] It should be further explained that, in some embodiments, Figure 4 A wheel groove is provided on the circumferential side of the guide wheel 2122 so that the guide wheel 2122 and the linear guide rail 2111 form a good fit.

[0066] As mentioned above, the frame 100 is a rectangular frame body, which is assembled by splicing multiple profiles. Specifically, firstly, two rectangular frames are spliced ​​by four profiles, and then the two rectangular frames are set in mirror symmetry. Then, four parallel profiles are set between the two rectangular frames, and the two ends of the four profiles are respectively connected to the four corners of the two mirror symmetric rectangular frames to form the frame 100. At this time, the frame 100 is a rectangular frame body. When the frame 100 is placed on the ground, as shown in FIG. Figure 1 As shown, the two parallel profiles in the mirror-symmetrical rectangular frame in the frame 100 are parallel to the ground, and the length direction of the two profiles is defined as the Y-axis direction, and the length direction of the two profiles in the mirror-symmetrical rectangular frame in the frame 100 that are perpendicular to the ground is the Z-axis direction, at this time the Z-axis direction is perpendicular to the Y-axis direction, and the length direction of the four profiles connecting the two rectangular frames is the X-axis direction, which is parallel to the ground and perpendicular to the plane formed by the Y-axis and the Z-axis.

[0067] In order to achieve coordination with the production process, the material receiving member 300 on the conveying device needs to achieve continuous movement to receive the tooling plate 600 delivered to the material placement surface by the previous process and transfer the tooling plate 600 there to the next process. The material receiving member 300 needs to repeat the above steps while moving along the guide rail. Therefore, in some embodiments, such as Figure 3 As shown, each lifting assembly 210 includes two linear guide rails 2111 and two semicircular guide rails 2112. The two linear guide rails 2111 are arranged in parallel with their ends aligned, and the length direction of the two linear guide rails 2111 is parallel to the Z-axis direction, while the two semicircular guide rails 2112 are respectively arranged at both ends of the two linear guide rails 2111. The radius of the semicircular guide rail 2112 is equal to the spacing between the two linear guide rails 2111, and the two ends of the semicircular guide rail 2112 are respectively connected to the two ends of the two linear guide rails 2111 in the same direction, so as to splice the two linear guide rails 2111 and the two semicircular guide rails 2112 into an annular guide rail 211, and each guide wheel 2122 in the sliding assembly 212 also needs to be adjusted in order to adapt to the annular guide rail 211, but the adjustment is a conventional adaptive adjustment in the field and need not be elaborated here.

[0068] In this embodiment, a combination design of a linear guide 2111 and a semicircular guide 2112 is adopted, and they are assembled into a ring guide 211 to form a stable guide structure. This effectively solves the problem of uneven sliding or uneven load-bearing caused by the unstable guide structure during the continuous movement of the conveying equipment in the prior art, thereby realizing the smooth and continuous movement of the material receiving part 300, ensuring the smooth transfer of the tooling plate 600 between different processes, and improving the stability and efficiency of the production process.

[0069] In some embodiments, Figure 1 and Figure 2 As shown, the lifting mechanism 200 further includes a first sprocket 230, a second sprocket 240 and a chain 250. The first sprocket 230 is connected to the frame 100 in a rotational connection manner, and the first sprocket 230 rotates in a controlled manner, the second sprocket 240 is connected to the frame 100 in a rotational connection manner, the first sprocket 230 is transmission-connected with the second sprocket 240 through the chain 250, so that the first sprocket 230 and the second sprocket 240 rotate synchronously, and the slide 2121 is connected to the chain 250, so that the slide 2121 is driven by the chain 250, so that the slide 2121 can move along the annular guide rail 211 in cooperation with the guide wheel 2122. The shape of the motion track of the chain 250 is configured to be the same as the annular guide rail 211 under the cooperation of the first sprocket 230 and the second sprocket 240, but the size of the motion track of the chain 250 is smaller than the size of the annular guide rail 211, and the motion track of the chain 250 is concentrically arranged with the annular guide rail 211, such as Figure 2 shown.

[0070] Specifically, when the number of lifting components 210 is four as described later, the number of chains 250 is also four, and each chain 250 corresponds to the first sprocket 230 and the second sprocket 240 in each lifting component 210, that is, one chain 250 corresponds to two sprockets (the first sprocket 230 and the second sprocket 240) arranged on the same side of the same support plate 213, and the two sprockets (the first sprocket 230 and the second sprocket 240) are connected by the chain 250, that is, when one sprocket (the first sprocket 230) rotates, the other sprocket (the second sprocket 240) of the same group will also rotate synchronously. The chain 250 is composed of a plurality of chain links, pins and sleeves, and adjacent chain links are connected by pins and sleeves. After a plurality of adjacent chain links are connected in sequence, a closed loop structure is formed, and the closed loop structure is the chain 250.

[0071] To further illustrate the connection relationship between the slide 2121 and the chain 250, the slide 2121 is fixedly mounted on the chain link of the chain 250 by fasteners, and the number of slides 2121 is determined as needed. Usually, the number of chain links between adjacent slides 2121 on the same chain 250 is equal, and each slide 2121 on the chain 250 is arranged parallel to each slide 2121 on the adjacent chain 250. In some embodiments, a connecting bracket is sometimes arranged between the slide 2121 and the material receiving member 300, and the connecting bracket is fixedly connected to the chain link of the chain 250. The connecting bracket at this location is the driving member 410, and the number of the driving members 410 is the same as the number of the slides 2121. Each slide 2121 is fixedly mounted with a driving member 410, and each driving member 410 on the chain 250 is arranged parallel to each driving member 410 on the adjacent chain 250.

[0072] In other embodiments, the lifting mechanism 200 further includes a first gear, a second gear and a synchronous belt, wherein the first gear and the second gear are both synchronous wheels, the first gear is connected to the frame 100 in a rotationally connected manner, and the first gear rotates in a controlled manner, the second gear is connected to the frame 100 in a rotationally connected manner, the first gear is transmission-connected to the second gear through a synchronous belt, so that the first gear and the second gear rotate synchronously, and the slide 2121 is connected to the synchronous belt, so that the slide 2121 is driven by the synchronous belt, so that the slide 2121 can move along the annular guide rail 211 in cooperation with the guide wheel 2122. The shape of the motion track of the synchronous belt is configured to be the same as that of the annular guide rail 211, but the size of the motion track of the synchronous belt is smaller than that of the annular guide rail 211, and the motion track of the synchronous belt is concentrically arranged with the annular guide rail 211.

[0073] In summary, whether the slide 2121 is connected to the chain 250 or the synchronous belt, the first sprocket 230 or the first gear rotates in a controlled manner. Figure 1 As shown, in some embodiments, the driving mechanism 400 further includes a driving shaft 420 and a driver 430, and the lifting mechanism 200 further includes a transmission shaft 220, the transmission shaft 220 is rotatably connected to the frame 100, the number of the transmission shafts 220 is two, and the two transmission shafts 220 are respectively connected to the first sprockets 230 in the two groups of lifting mechanisms 200 or the first gears in the two groups of lifting mechanisms 200, so that the first sprockets 230 or the first gears rotate synchronously with the transmission shaft 220. The driving shaft 420 rotates in a controlled manner, the driving shaft 420 is rotatably connected to the frame 100, and the driving shaft 420 is connected to the two transmission shafts 220 (the two transmission shafts 220 in the two groups of lifting mechanisms 200) in a mirrored manner, so that the two transmission shafts 220 rotate synchronously with the driving shaft 420, and the driver 430 is connected to the driving shaft 420 in a rotatable manner, so that the driving shaft 420 rotates synchronously.

[0074] Specifically, the transmission shaft 220 is rotationally connected to the support plate 213, that is, one transmission shaft 220 is rotationally connected to each support plate 213 in a group of lifting mechanisms 200 at the same time. Specifically, the axis of the transmission shaft 220 is parallel to the Y-axis direction, and the first sprockets 230 on each support plate 213 are all sleeved on the outside of the transmission shaft 220 to rotate with the transmission shaft 220. Therefore, after one transmission shaft 220 rotates, the first sprockets 230 on each support plate 213 in the same group of lifting mechanisms 200 will rotate synchronously.

[0075] In order to make the two lifting mechanisms 200 run synchronously, a driver 430 can be used to provide power. The conveying device also includes a transmission assembly 700, which is a transmission mechanism composed of multiple helical gears, and can change the transmission direction, such as Figure 1 Each transmission assembly 700 is equipped with a transmission shaft 220, that is, one transmission shaft 220 is only compatible with one transmission assembly 700, and the two transmission assemblies 700 are installed on the frame 100, and the two transmission assemblies 700 are respectively installed at the ends of the two drive shafts 420 located on the same side, and the two ends of the drive shaft 420 are respectively connected to the input ends of the two transmission assemblies 700, and the ends of the transmission shafts 220 in the two lifting mechanisms 200 facing the corresponding transmission assembly 700 are both connected to the output ends of the corresponding transmission assembly 700, so that the two transmission shafts 220 can rotate synchronously when the output shaft of the driver 430 rotates.

[0076] The driver 430 can be embodied as a driving motor in a specific manner. The driver 430 is fixedly mounted on the mounting frame 100. The driving shaft 420 is connected to the output shaft of the driving motor through a transmission gear mechanism (reducer and other devices). When the output shaft of the driving motor rotates, the driving shaft 420 rotates synchronously, and the axial direction of the driving shaft 420 is parallel to the X-axis.

[0077] Furthermore, in order to adapt to the frequency of loading and unloading of the tooling plate 600, such as Figure 1 and Figure 2 As shown, in some embodiments, each lifting assembly 210 includes a plurality of sliding assemblies 212 , and each sliding assembly 212 has a corresponding material receiving member 300 .

[0078] In summary, the conveying equipment adopts the method of combining the linear guide 2111 and the semicircular guide 2112 in the lifting component 210 into an annular guide 211, and combining the transmission design of the chain 250 or the synchronous belt of the lifting mechanism 200, so that the slide 2121 can move smoothly and continuously along the annular guide 211, thereby realizing the fast, stable and reliable movement of the material receiving part 300 during the high-frequency loading and unloading process of the tooling plate 600, and significantly improving the adaptability and production efficiency of the conveying equipment.

[0079] It can be understood that, in some embodiments, in order to facilitate installation and provide support, the lifting assembly 210 also includes a support plate 213, and the support plate 213 is arranged on the frame 100. Each annular guide rail 211 and the sliding assembly 212 are installed on one side of the support plate 213, and the first sprocket 230 (first gear), the second sprocket 240 (second gear) and the chain 250 (synchronous belt) are also installed on one side of the support plate 213, and each support plate 213 is connected to an annular guide rail 211, a first sprocket 230 (first gear), a second sprocket 240 (second gear) and a chain 250 (synchronous belt).

[0080] Specifically, each support plate 213 is fixedly connected to the frame 100 by a fastener. When the number of the lifting components 210 is four as described later, the number of the support plates 213 is also four, and each two support plates 213 form a group. The two support plates 213 in each group are arranged in parallel, and the two support plates 213 are arranged along the Y-axis direction. The two groups of support plates 213 are arranged in mirror symmetry, and the mirror axis is parallel to the Z-axis. At this time, the thickness direction of the support plate 213 is parallel to the Y-axis direction, the length direction of the support plate 213 is parallel to the Z-axis direction, and the width direction of the support plate 213 is parallel to the X-axis direction. The support plate 213 is composed of a rectangular plate and two semicircular plates. The length, width and height of the rectangular plate are respectively parallel to the length, width and height of the support plate 213. The diameter of the semicircular plate is equal to the width of the rectangular plate, and the thickness of the semicircular plate is also equal to the thickness of the rectangular plate. The semicircular plate is fixed to the side of the rectangular plate corresponding to the short side (width). The thickness of the semicircular plate is parallel to the thickness direction of the rectangular plate, and the edge contour of the arc surface of the semicircular plate is tangent to the two side surfaces corresponding to the long side (length) of the rectangular plate. At this time, the edge contour shape of the support plate 213 is the same as the shape of the annular guide rail 211, but the edge contour size of the support plate 213 is larger than the size of the annular guide rail 211, and the annular guide rail 211 is concentrically arranged with the support plate 213.

[0081] In order to improve the stability of the tooling board 600 during the transportation process and improve the bearing capacity of the tooling board 600, Figure 1 As shown, in some embodiments, the material supporting member 300 is a long strip structure, and the number of lifting components 210 in each group of lifting mechanisms 200 is two, and the slide seats 2121 in the two lifting components 210 are respectively arranged at the two ends corresponding to the long sides of the material supporting member 300, so that the tooling plate 600 corresponds to the four lifting components 210, and the four lifting components 210 are respectively located on the opposite sides of the tooling plate 600, thereby enhancing the supporting surface of the material supporting member 300 and further ensuring the stability of the material supporting member 300. In addition, the long strip material supporting member 300 also increases the contact area between the material supporting member 300 and the tooling plate 600, thereby improving the bearing capacity of the tooling plate 600.

[0082] Specifically, each material receiving member 300 is connected to a slide seat 2121. At this time, the length direction of the material receiving member 300 is parallel to the Y-axis direction, the width direction of the material receiving member 300 is parallel to the X-axis direction, and the thickness direction of the material receiving member 300 is parallel to the Z-axis direction.

[0083] In this embodiment, due to the technical means of designing the material receiving member 300 as a long strip structure and configuring two lifting components 210 in each lifting mechanism 200, the slide seats 2121 are respectively arranged at the two ends of the long side of the material receiving member 300, thereby increasing the contact area between the material receiving member 300 and the tooling plate 600, and effectively solving the problem of tilting caused by insufficient bearing capacity of the tooling plate 600 during transportation in the prior art, thereby achieving higher bearing capacity and better stability of the tooling plate 600 during transportation, and significantly improving the reliability of the conveying equipment and the accuracy of the tooling plate 600 transportation.

[0084] In order to facilitate the loading and unloading of the tooling plate 600, the conveying equipment also includes a plurality of guide components 500, each of which is arranged at the material receiving surface 310 of each material receiving member 300 in a one-to-one corresponding manner, and the guide components 500 include a plurality of rollers 510, and the plurality of rollers 510 are all arranged at the material receiving surface 310 of the material receiving member 300 in a rotatable manner, and the axes of each roller 510 on the material receiving surface 310 are all arranged in a preset plane, and the preset plane is parallel to the material receiving surface 310, and the rotation planes of each roller 510 on the material receiving surface 310 are arranged in parallel, and the rotation planes of each roller 510 are perpendicular to the material receiving surface 310, at this time, the highest points of the plurality of rollers 510 on the material receiving surface 310 away from the material receiving member 300 are coplanar to form a conveying surface, and the conveying direction is the rotation direction of the rollers 510, and the tooling plate 600 is placed on the conveying surface after being transferred to the conveying equipment.

[0085] Specifically, there are several rollers 510, and several rollers 510 are equally divided into multiple groups, and the number of groups of rollers 510 is the same as the number of the material receiving member 300. Each group of rollers 510 corresponds to each material receiving member 300 one by one, that is, a group of rollers 510 are installed at the material receiving surface 310 of each material receiving member 300, and each roller 510 is installed on the side of the material receiving member 300 away from the frame 100. The shape of the roller 510 is a columnar body. In some embodiments, the two ends of each roller 510 on the material receiving member 300 are arranged flush, and the distance between adjacent rollers 510 is equal. It should be noted that the roller 510 is installed at the material receiving surface 310 of the material receiving member 300 through a bearing and a rotating shaft. At this time, the roller 510 can only rotate around its own axis, and the axis of the roller 510 is colinear with the axis of the rotating shaft.

[0086] In this embodiment, since a guide assembly 500 is adopted and a plurality of rollers 510 are arranged on the material receiving surface 310, the rotation planes of these rollers 510 are parallel to the material receiving surface 310 and perpendicular to one side of the material receiving member 300 to form a stable conveying surface, thereby effectively solving the problem of excessive sliding friction during loading and unloading when the tooling plate 600 is heavy, thereby achieving smooth loading and unloading and efficient conveying of the tooling plate 600, and improving the overall transmission efficiency and operating stability of the conveying equipment.
