Description

Technical Field

[0001] This invention relates to the field of multi-station carrier technology, and more particularly to a variable-pitch carrier device. Background Technology

[0002] Multi-station carriers are mainly used for batch carrying and positioning of workpieces. Existing multi-station carriers that are compatible with multiple workpiece specifications are usually equipped with independent adjustment mechanisms in the first and second directions at each station, so as to realize the size adaptation adjustment of a single station in the first or second direction.

[0003] Although this structure can achieve independent size adjustment of a single station to adapt to workpieces of different specifications, it cannot achieve synchronous linkage adjustment of multiple stations in the first or second direction because each station can only be controlled individually. Furthermore, due to the stacked arrangement of multiple independent adjustment components, the overall structure of the multi-station carrier is more complex, with larger weight and volume. Summary of the Invention

[0004] The purpose of this invention is to provide a variable pitch bearing device that can achieve multi-station size adjustment, and has a relatively simple overall structure with small weight and volume.

[0005] To achieve this objective, the present invention adopts the following technical solution: A variable pitch load-bearing device, comprising: Base; The bearing device includes at least three bearing beams and at least three bearing mechanisms. The bearing beams are movably disposed on the base at intervals along a first direction and all extend along a second direction. The bearing mechanisms are spaced apart along a second direction perpendicular to the first direction. Each bearing mechanism includes multiple support components. The multiple support components in each bearing mechanism are movably disposed on each bearing beam in a one-to-one correspondence. The multiple support components cooperate to form at least four bearing spaces in a matrix distribution. An adjustment device is disposed on the base. The adjustment device includes a first adjustment mechanism and / or a second adjustment mechanism. The first adjustment mechanism is driven to at least one of the bearing beams to drive the corresponding bearing beams to reciprocate along a first direction to adjust the size of at least one bearing space in the first direction. The second adjustment mechanism is driven to at least one of the bearing mechanisms to drive the corresponding bearing mechanism to reciprocate along a second direction to adjust the size of at least one bearing space in the second direction.

[0006] As a further technical solution, four load-bearing beams are provided, and each load-bearing mechanism includes an adjusting rod and four support components connected to the corresponding adjusting rod. The second adjusting mechanism includes a second transmission component and two second adjusting blocks. The two second adjusting blocks are tractively connected to the second transmission component. The second transmission component is configured to drive the two second adjusting blocks to move closer to or further away from each other along a second direction, and the two second adjusting blocks are tractively connected to at least one adjusting rod.

[0007] As a further technical solution, the bearing mechanism is provided with four sets, and the second transmission component includes two synchronous adjustment members. Both synchronous adjustment members extend in a long strip shape along the second direction and are connected to the two second adjustment blocks in a corresponding transmission manner. One of the synchronization adjustment members in the second transmission assembly has its two ends respectively connected to two of the adjustment rods, and the other synchronization adjustment member has its two ends respectively connected to the other two adjustment rods.

[0008] As a further technical solution, the four sets of bearing mechanisms are sequentially referred to as the first bearing mechanism, the second bearing mechanism, the third bearing mechanism, and the fourth bearing mechanism along the second direction. One of the synchronous adjustment members is driven to the first bearing mechanism and the third bearing mechanism at both ends, and the other synchronous adjustment member is driven to the second bearing mechanism and the fourth bearing mechanism at both ends.

[0009] As a further technical solution, the second transmission assembly also includes two auxiliary adjustment components, which extend in a long strip shape along the second direction. One of the auxiliary adjustment components is connected at both ends to the first bearing mechanism and the third bearing mechanism, respectively, and the other auxiliary adjustment component is connected at both ends to the second bearing mechanism and the fourth bearing mechanism, respectively.

[0010] As a further technical solution, the second adjustment mechanism further includes at least one set of second detection components, which are correspondingly arranged with the second adjustment block and are used to detect the movement distance of the corresponding second adjustment block along the second direction.

[0011] As a further technical solution, the first adjustment mechanism includes a first transmission component and two first adjustment blocks. The two first adjustment blocks are tractively connected to the first transmission component. The first transmission component is configured to drive the two first adjustment blocks to move closer to or further away from each other in a first direction. The two first adjustment blocks are tractively connected to at least one of the bearing beams.

[0012] As a further technical solution, along the first direction, four load-bearing beams are spaced apart, and two of the first adjusting blocks are connected one-to-one to the two load-bearing beams located in the middle.

[0013] As a further technical solution, the first adjustment mechanism includes at least one set of first detection components, which are correspondingly arranged with the first adjustment block and are used to detect the movement distance of the corresponding first adjustment block along the first direction.

[0014] As a further technical solution, the support component includes a support block, which is slidably disposed on the corresponding load-bearing beam along the second direction, and the support block is provided with an installation channel that allows the corresponding adjusting rod to pass through.

[0015] As a further technical solution, the support component also includes a support column, which is disposed on one side corresponding to the support block and extends in the vertical direction.

[0016] As a further technical solution, the base includes a base plate and two bearing walls disposed on the upper surface of the base plate. The two bearing walls are arranged at intervals relative to each other along a second direction and both extend along a first direction. The two ends of each bearing beam are slidably disposed on the two bearing walls respectively, and the adjustment device is disposed on the base plate.

[0017] Compared with the prior art, the beneficial effects of the variable pitch bearing device provided in the embodiments of the present invention are as follows: Since multiple load-bearing beams are movably arranged at intervals along the first direction on the base, and the first adjustment mechanism is arranged on the base and is drivenly connected to at least one load-bearing beam to drive the corresponding load-bearing beam to reciprocate along the first direction, when the first adjustment mechanism drives at least one load-bearing beam to move along the first direction, the size of at least two of the load-bearing spaces along the first direction can be changed. Furthermore, since there are at least three sets of load-bearing mechanisms, with multiple sets of load-bearing mechanisms arranged at intervals along the second direction, and multiple support components in the same set of load-bearing mechanisms movably arranged one-to-one on multiple load-bearing beams, and the second adjustment mechanism is arranged on the base and is drivenly connected to at least one load-bearing beam, when the second adjustment mechanism drives at least one load-bearing mechanism to reciprocate along the second direction, the size of at least two of the load-bearing spaces along the second direction can be changed. Thus, by cooperating with the first and second adjustment mechanisms and the load-bearing device, the size of the load-bearing space in the first and second directions can be changed according to the specific size of the workpiece to be carried, thereby achieving the carrying and positioning operation of the workpiece to be carried. In the overall structure, by setting a first adjustment mechanism and a second adjustment mechanism, the size adjustment of multiple bearing spaces can be realized without setting a corresponding first adjustment mechanism and second adjustment mechanism for each bearing space. This reduces the number of adjustment mechanisms, simplifies the overall structure of the variable pitch bearing device, and reduces the overall weight and volume of the variable pitch bearing device.

[0021] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0022] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0023] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0024] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0025] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0026] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0027] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0028] This embodiment provides a variable-pitch bearing device, which can achieve multi-station size adjustment and has a relatively simple overall structure with small weight and volume. The variable-pitch bearing device includes a base 100, a bearing device 200, and an adjustment device 300. The bearing device 200 includes at least three bearing beams 210 and at least three bearing mechanisms 201. The bearing beams 210 are movably arranged at intervals along a first direction on the base 100 and extend along a second direction perpendicular to the first direction. The bearing mechanisms 201 are spaced apart along the second direction. Each bearing mechanism 201 includes multiple support components 220. Each support component 220 in each bearing mechanism 201 is movably arranged correspondingly to each bearing beam 210, and the multiple support components 220 cooperate to form a matrix. The fabric has at least four support spaces 202; an adjustment device 300 is disposed on the base 100, the adjustment device 300 includes a first adjustment mechanism 310 and / or a second adjustment mechanism 320, the first adjustment mechanism 310 is driven to at least one support beam 210 to drive the corresponding support beam 210 to reciprocate along a first direction to adjust the size of at least one support space 202 in the first direction, and the second adjustment mechanism 320 is driven to at least one support mechanism 201 to drive the corresponding support mechanism 201 to reciprocate along a second direction to adjust the size of at least one support space 202 in the second direction.

[0029] In this embodiment, the first direction is the X direction in the attached figure, and the second direction is the Y direction in the attached figure.

[0030] Specific combination Figure 1 , Figure 2 , Figure 4 as well as Figure 8 and Figure 9As shown, since multiple load-bearing beams 210 are movably arranged at intervals along the first direction on the base 100, and the first adjustment mechanism 310 is disposed on the base 100 and is connected to at least one load-bearing beam 210 in a transmission manner to drive the corresponding load-bearing beam 210 to reciprocate along the first direction, when the first adjustment mechanism 310 drives at least one load-bearing beam 210 to move along the first direction, the size of at least two of the load-bearing spaces 202 along the first direction can be changed; and since at least three sets of load-bearing mechanisms 201 are provided, multiple sets of load-bearing mechanisms 201 are arranged at intervals along the second direction, and multiple support components 220 in the same set of load-bearing mechanisms 201 are movably arranged one-to-one with the multiple load-bearing beams 210. The second adjustment mechanism 320 is disposed on the base 100 and is drive-connected to at least one bearing beam 210. The second adjustment mechanism 320 is also drive-connected to at least one bearing mechanism 201. Therefore, when the second adjustment mechanism 320 drives at least one bearing mechanism 201 to reciprocate along the second direction, the dimensions of at least two of the bearing spaces 202 along the second direction can be changed. Thus, through the cooperation of the first adjustment mechanism 310 and the second adjustment mechanism 320 with the bearing device 200, the dimensions of the bearing spaces 202 in the first and second directions can be changed according to the specific dimensions of the workpiece to be carried, thereby achieving the carrying and positioning operations of the workpiece. In the overall structure, by setting a set of first adjustment mechanisms 310 and a set of second adjustment mechanisms 320, the dimensions of multiple bearing spaces 202 can be adjusted without needing to set a corresponding first adjustment mechanism 310 and second adjustment mechanism 320 for each bearing space 202. This reduces the number of adjustment mechanisms, simplifies the overall structure of the variable-pitch bearing device, and reduces the overall weight and volume of the variable-pitch bearing device.

[0031] In this embodiment, four load-bearing beams 210 and four load-bearing mechanisms 201 are provided, resulting in a total of sixteen sets of support components 220. These sixteen sets of support components 220 are arranged in a grid pattern and cooperate with each other to form four load-bearing spaces 202. Specifically, in conjunction with... Figure 9 As shown, with this configuration, there is a clearance area between two adjacent carrying spaces 202 along the first and second directions, while making the four carrying spaces 202 relatively independent. When the first adjustment mechanism 310 and the second adjustment mechanism 320 are activated to adjust the size of the carrying space 202, the size adjustment amount of the carrying space 202 in the first and second directions can be the same or different to adapt to workpieces of different specifications.

[0032] In other embodiments, three support beams 210 can be provided. Along the first direction, two adjacent support spaces 202 share one support beam 210. When the middle support beam 210 is connected to the first adjustment mechanism 310, the first adjustment mechanism 310 drives the support beam 210 to reciprocate along the first direction, thereby simultaneously changing the size of the four support spaces 202 in the first direction. Furthermore, along the first direction, the sizes of two adjacent support spaces 202 are not the same. Similarly, three support mechanisms 201 can be provided. Along the second direction, two adjacent support spaces 202 share one support mechanism 201. When two adjacent support spaces 202 in the middle share a second adjustment mechanism 320, the second adjustment mechanism 320 drives the support mechanism 201 to reciprocate along the second direction, thereby simultaneously changing the size of the four support spaces 202 in the second direction. Furthermore, along the second direction, the sizes of two adjacent support spaces 202 are not the same. This allows for the support and positioning of workpieces of different specifications in the same batch.

[0033] In an optional embodiment, the bearing mechanism 201 includes an adjusting rod 230 and four support components 220 connected to the corresponding adjusting rod 230. The second adjusting mechanism 320 includes a second transmission component 321 and two second adjusting blocks 322. The two second adjusting blocks 322 are tractively connected to the second transmission component 321. The second transmission component 321 is configured to drive the two second adjusting blocks 322 to move closer to or further away from each other along a second direction. The two second adjusting blocks 322 are tractively connected to at least one adjusting rod 230.

[0034] Combination Figure 2 , Figure 3 and Figure 6As shown, in this embodiment, the second transmission assembly 321 includes a second adjusting motor 3215, a second mounting base 3216, a second adjusting belt 3211, and two second adjusting pulleys 3212. The second adjusting motor 3215 and the second mounting base 3216 are spaced apart on the base 100 along a second direction. One of the second adjusting pulleys 3212 is tractively connected to the motor shaft of the second adjusting motor 3215, and the other second adjusting pulley 3212 is movably mounted on the second mounting base 3216. The second adjusting belt 3211 is tractively connected to the two second adjusting pulleys 3212. Two second adjusting blocks 322 are tractively connected to the upper and lower sides of the second adjusting belt 3211, respectively, and both extend upward. The upper sides of the two second adjusting blocks 322 are tractively connected to at least one adjusting rod 230. Thus, when the motor shaft of the second adjusting motor 3215 rotates forward or backward, it drives the two second adjusting blocks 322 to move closer or further apart, thereby driving the corresponding bearing mechanism 201 to move closer or further apart in the second direction, thereby changing the size of the four bearing spaces 202 in the second direction. Furthermore, to avoid jamming, the arc length displacement of the motor shaft of the second adjusting motor 3215 driving the corresponding second adjusting pulley 3212 to rotate is less than or equal to the maximum distance between the two second adjusting pulleys 3212. Both second adjusting blocks 322 have clearance spaces in their middle sections to avoid the second adjusting belt 3211. Furthermore, to further improve the convenience of the two second adjusting blocks 322 moving closer or further apart and to limit their paths of approach or departure, the lower ends of both second adjusting blocks 322 are slidably mounted on the base 100 via a slide rail and groove structure. A first mounting base 3114 is movably mounted on the base 100 along a first direction, and a first tensioning seat and a first tensioning shaft 314 are provided corresponding to the first mounting base 3114. The first tensioning seat is fixed to the base 100, and both ends of the first tensioning shaft 314 are threaded to the first mounting base 3114 and the first tensioning seat, respectively. By turning the first tensioning shaft 314, the distance between the first tensioning seat and the first adjusting motor 3113 is changed, thereby adaptively adjusting the tension of the first adjusting pulley 3112 to ensure its performance and service life.

[0035] Alternatively, in some other embodiments, the second transmission assembly 321 may also be configured to include a second adjusting motor 3215, a second mounting base 3216, a second adjusting chain belt, and two second adjusting sprockets. The second adjusting motor 3215 and the second mounting base 3216 are spaced apart from each other along a second direction on the base 100. One of the second adjusting sprockets is driven to the motor shaft of the second adjusting motor 3215, and the other second adjusting sprocket is movably disposed on the second mounting base 3216. The second adjusting chain belt is driven to the two second adjusting sprockets. Two second adjusting blocks 322 are driven to the upper and lower sides of the second adjusting chain belt, respectively, and both extend upward. The upper sides of the two second adjusting blocks 322 are driven to at least one adjusting rod 230.

[0036] In the two embodiments described above, the second regulating motor 3215 can be configured as a DC motor, a servo motor, or an equiaxial rotation motor.

[0037] In some other embodiments, the second transmission assembly 321 includes two push rod motors, the motor shafts of the two push rod motors are arranged opposite to each other and both extend and retract in the second direction, and two second adjustment blocks 322 are respectively connected to the motor shafts of the two push rod motors. When the motor shafts of the two push rod motors extend and retract, they drive the two second adjustment blocks 322 to move closer to each other or away from each other, thereby changing the size of the four bearing spaces 202 in the second direction.

[0038] Furthermore, the bearing mechanism 201 is provided with four sets. The second transmission assembly 321 includes two synchronous adjustment members 3213, both of which extend in a long strip shape along the second direction and are correspondingly connected to the two second adjustment blocks 322. The two ends of one of the synchronous adjustment members 3213 are respectively connected to two adjustment rods 230, and the two ends of the other synchronous adjustment member 3213 are respectively connected to the other two adjustment rods 230. With this arrangement, when the two second adjustment blocks 322 are close to each other, the size of at least one bearing space 202 in the second direction increases, and when the two second adjustment blocks 322 are far apart, the size of at least one bearing space 202 in the second direction decreases, thereby improving the applicability of the bearing space 202.

[0039] Specifically, the four sets of bearing mechanisms 201 are sequentially referred to as the first bearing mechanism, the second bearing mechanism, the third bearing mechanism, and the fourth bearing mechanism along the second direction. One of the synchronous adjustment members 3213 is connected to the first bearing mechanism and the third bearing mechanism at both ends, and the other synchronous adjustment member 3213 is connected to the second bearing mechanism and the fourth bearing mechanism at both ends.

[0040] The first and second support mechanisms cooperate to form two support spaces 202 spaced apart along the first direction. Similarly, the third and fourth support mechanisms cooperate to form two support spaces 202 spaced apart along the first direction. When the two second adjusting blocks 322 move closer together, the size of each support space 202 increases in the second direction; when the two second adjusting blocks 322 move further apart, the size of each support space 202 decreases in the second direction. Because the positions of the four support mechanisms 201 can be adjusted, the applicability of the support spaces 202 can be improved. That is, in a single adjustment process, the size of multiple support spaces 202 can be adjusted simultaneously in the second direction.

[0041] In other embodiments, one of the synchronous adjustment members 3213 may be configured such that its two ends are respectively driven to the first and fourth bearing mechanisms, and its two ends are respectively driven to the second and third bearing mechanisms. This achieves synchronous adjustment of the dimensions of multiple bearing spaces 202 along the first direction. Alternatively... When the area between the second and third bearing mechanisms also serves as the bearing space 202, it can be configured such that one of the synchronous adjustment members 3213 is connected to the first and second bearing mechanisms at both ends, and the other synchronous adjustment member 3213 is connected to the third and fourth bearing mechanisms at both ends. With this configuration, when the second adjusting motor 3215 is running, the dimensions of the bearing space 202 formed by the cooperation of the first and second bearing mechanisms, and the bearing space 202 formed by the cooperation of the third and fourth bearing mechanisms, remain unchanged in the second direction; only the dimension of the bearing space 202 formed by the cooperation of the second and third bearing mechanisms changes in the second direction.

[0042] Furthermore, the second transmission assembly 321 also includes two auxiliary adjusting members 3214, which extend in a long strip shape along the second direction. One auxiliary adjusting member 3214 has its two ends connected to the first and third supporting mechanisms, respectively, while the other auxiliary adjusting member 3214 has its two ends connected to the second and fourth supporting mechanisms, respectively. Figure 1 and Figure 7As shown, since the first and third bearing mechanisms 201 are relatively long in the second direction, the auxiliary adjustment component 3214 can improve the consistency of movement in the second and first directions on the same side of the first and third bearing mechanisms, as well as on the same side of the second and fourth bearing mechanisms, thereby ensuring the stability and accuracy of adjustment of the corresponding bearing space 202. Simultaneously, the middle part of the auxiliary adjustment component 3214 connected to the first and third bearing mechanisms has a clearance area corresponding to the adjustment rods 230 in the first and third bearing mechanisms. Similarly, the middle part of the auxiliary adjustment component 3214 connected to the second and fourth bearing mechanisms also has a clearance area corresponding to the adjustment rods 230 in the second and fourth bearing mechanisms. This arrangement facilitates overall assembly while preventing interference between the adjustment rods 230 and the auxiliary adjustment component 3214. In some other embodiments, an auxiliary adjustment member 3214 is provided between the support component 220 on the other side of the first support mechanism and the support component 220 on the other side of the third support mechanism; at the same time, auxiliary adjustment members 3214 are also provided between the support components 220 on both sides of the second support mechanism and the support components 220 on both sides of the fourth support mechanism. In this embodiment, the number of auxiliary adjustment members 3214 is not specifically limited.

[0043] In other embodiments of this solution, the second adjustment mechanism 320 further includes at least one set of second detection components 323, which are correspondingly arranged with the second adjustment block 322 and are used to detect the moving distance of the corresponding second adjustment block 322 along the second direction.

[0044] Combination Figure 3 As shown, in this embodiment, two sets of second detection components 323 are provided, with each set corresponding to one of the two second adjustment blocks 322. Each second detection component 323 includes a second detector 3231 and a second detection plate 3232. The second detection plate 3232 is disposed on the corresponding second adjustment block 322, and the second detector 3231 is disposed on the base 100. The second detector 3231 is communicatively connected to a display (not shown in the figure). Through the cooperation of the second detector 3231 and the second detection plate 3232, the movement distance of the corresponding second adjustment block 322 along the second direction is detected and displayed on the display, so that the operator can adjust the size of the bearing space 202 in the second direction according to the size of the workpiece to be carried. At the same time, the two sets of second detection components 323 serve as a control group. When the two sets of second detection components 323 detect that the movement distances of the two second adjustment blocks 322 are inconsistent, it indicates that the second adjustment belt 3211 may be loose or deformed, so that the operator can carry out timely maintenance. The working principle of the second detector 3231 and the second detection board 3232 is the same as that of the prior art and will not be described in detail here.

[0045] In the optional technical solution of this embodiment, the first adjustment mechanism 310 includes a first transmission component 311 and two first adjustment blocks 312. The two first adjustment blocks 312 are both connected to the first transmission component 311. The first transmission component 311 is configured to drive the two first adjustment blocks 312 to move closer to each other or away from each other along a first direction. The two first adjustment blocks 312 are respectively connected to at least one bearing beam 210.

[0046] Combination Figure 2 and Figure 3 As shown, the first transmission assembly 311 includes a first adjusting motor 3113, a first mounting base 3114, a first adjusting belt 3111, and two first adjusting pulleys 3112. The first adjusting motor 3113 and the first mounting base 3114 are spaced apart on the base 100 along a first direction. One of the first adjusting pulleys 3112 is driven to the motor shaft of the first adjusting motor 3113, and the other first adjusting pulley 3112 is movably disposed on the first mounting base 3114. The first adjusting belt 3111 is driven to the two first adjusting pulleys 3112. Two first adjusting blocks 312 are driven to the upper and lower sides of the first adjusting belt 3111, respectively, and both extend upward. The upper sides of the two first adjusting blocks 312 are driven to two of the bearing beams 210. Specifically, in this embodiment, along the first direction, the two first adjusting blocks 312 are connected one-to-one to the two bearing beams 210 located in the middle. Therefore, when the motor shaft of the first adjusting motor 3113 rotates forward or backward, it drives the two first adjusting blocks 312 to move closer or further apart, thereby driving the two supporting beams 210 located in the middle to move closer or further apart in the first direction, thus changing the size of the four supporting spaces 202 in the first direction. Furthermore, to avoid jamming, the arc length displacement of the motor shaft of the first adjusting motor 3113 that drives the corresponding first adjusting pulley 3112 to rotate is less than or equal to the maximum distance between the two first adjusting pulleys 3112. Both first adjusting blocks 312 have clearance spaces in their middle sections to avoid the first adjusting belt 3111. Furthermore, to further improve the convenience of the two first adjusting blocks 312 moving closer or further apart and to limit their paths of approach or departure, the lower ends of both first adjusting blocks 312 are slidably mounted on the base 100 via a slide rail and groove structure. A first mounting seat 3114 is movably mounted on the base 100 along a first direction, and a first tensioning seat and a first tensioning shaft 314 are provided corresponding to the first mounting seat 3114. The first tensioning seat is fixed to the base 100, and both ends of the first tensioning shaft 314 are threaded to the first mounting seat 3114 and the first tensioning seat, respectively. By turning the first tensioning shaft 314, the distance between the first tensioning seat and the first adjusting motor 3113 is changed, thereby adaptively adjusting the tension of the first adjusting pulley 3112 to ensure its performance and service life.

[0047] Alternatively, in some other embodiments, the first transmission assembly 311 may also be configured to include a first adjusting motor 3113, a first mounting base 3114, a first adjusting chain belt, and two first adjusting sprockets. The first adjusting motor 3113 and the first mounting base 3114 are spaced apart on the base 100 along a first direction. One of the first adjusting sprockets is driven to the motor shaft of the first adjusting motor 3113, and the other first adjusting sprocket is movably disposed on the first mounting base 3114. The first adjusting chain belt is driven to the two first adjusting sprockets. Two first adjusting blocks 322 are driven to the upper and lower sides of the first adjusting chain belt, respectively, and both extend upward. The upper sides of the two first adjusting blocks 322 are driven to at least one adjusting rod 230.

[0048] In the two embodiments described above, the first regulating motor 3113 can be configured as a DC motor, a servo motor, or an equiaxial rotation motor.

[0049] In some other embodiments, the first transmission assembly 311 includes two push rod motors, the motor shafts of the two push rod motors are arranged opposite to each other and both extend and retract in a first direction, and two first adjustment blocks 312 are respectively connected to the motor shafts of the two push rod motors. When the motor shafts of the two push rod motors extend and retract, they drive the two first adjustment blocks 312 to move closer to each other or away from each other, thereby changing the size of the four bearing spaces 202 in the first direction.

[0050] In other embodiments, the upper sides of the two first adjusting blocks 312 can be drivenly connected to any two bearing beams 210 respectively. For example, the upper sides of the two first adjusting blocks 312 can be drivenly connected to two bearing beams 210 located on both sides along the first direction respectively, so as to change the size of the four bearing spaces 202 in the first direction, not limited to this embodiment.

[0051] Furthermore, the first adjustment mechanism 310 also includes at least one set of first detection components 313, which are correspondingly arranged with the first adjustment block 312 and are used to detect the moving distance of the corresponding first adjustment block 312 along the first direction.

[0052] Combination Figure 5As shown, in this embodiment, two sets of first detection components 313 are provided, with each set corresponding to one of the two first adjustment blocks 312. Each first detection component 313 includes a first detector 3131 and a first detection plate 3132. The first detection plate 3132 is disposed on the corresponding first adjustment block 312, and the first detector 3131 is disposed on the base 100. The first detector 3131 is communicatively connected to a display (not shown in the figure). The first detector 3131 and the first detection plate 3132 cooperate to detect the movement distance of the corresponding first adjustment block 312 along the first direction and display it on the display, so that the operator can adjust the size of the bearing space 202 in the first direction according to the size of the workpiece to be carried. At the same time, the two sets of first detection components 313 serve as a control group. When the two sets of first detection components 313 detect that the movement distances of the two first adjustment blocks 312 are inconsistent, it indicates that the first adjustment belt 3111 may be loose or deformed, so that the operator can carry out timely maintenance.

[0053] In the optional technical solution of this embodiment, the support component 220 includes a support block 221, which is slidably disposed on the corresponding bearing beam 210 along the second direction, and the support block 221 is provided with an installation channel that allows the corresponding adjusting rod 230 to pass through.

[0054] Combination Figure 1 As shown, the upper end of each support beam is configured as a slide rail, and the lower end of each support block 221 is correspondingly configured as a slide groove. Each support block 221 is slidably mounted on its corresponding slide rail to improve the ease of movement of each support block 221 along the second direction. After the workpiece is placed in the bearing space 202, the four support blocks 221 in the bearing space 202 are used to support the workpiece. By providing mounting through holes on the support blocks 221, the connection strength and stability of the four support blocks 221 in the same bearing mechanism 201 when connected to the same adjusting rod 230 are improved, so as to ensure the uniformity of the sliding of the four support blocks 221 in the same bearing mechanism 201 along the second direction.

[0055] Furthermore, the support assembly 220 also includes a support column 222, which is disposed on one side of the corresponding support block 221 and extends in the vertical direction.

[0056] Combination Figure 1 As shown, the support column 222 has a clearance zone on the side facing the corresponding bearing space 202 to avoid interference with the workpiece to be supported. By setting the support column 222, the workpiece located in the bearing space 202 can be positioned in the first and second directions.

[0057] In the optional technical solution of this embodiment, the base 100 includes a base plate 110 and two bearing walls 120 disposed on the upper surface of the base plate 110. The two bearing walls 120 are disposed at intervals relative to each other along the second direction and both extend along the first direction. The two ends of each bearing beam 210 are respectively slidably disposed on the two bearing walls 120. The adjustment device 300 is disposed on the base plate 110.

[0058] Combination Figure 1 Figure 2 and Figure 4 As shown, the base plate 110 and the two supporting walls 120 cooperate to form an accommodating space. The adjusting device 300 is set on the base plate 110 and located in the accommodating space. In this way, when adjusting the size of the supporting space 202, interference between the adjusting device 300 and the supporting device 200 can be avoided. At the same time, the interference of external debris on the adjusting device 300 is reduced.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
