Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a multi-station variable-distance manipulator. Background Art

[0002] During the manufacturing process, multi-station robots (with multiple gripping stations, or grippers) are needed to handle material handling and turnover to improve production efficiency. Existing multi-station robots have multiple grippers, each with its own independent drive unit, which adjusts the spacing between the grippers to accommodate materials of varying sizes. This results in a larger overall size and weight, higher costs, and a more complex structure. Utility Model Content

[0003] The purpose of the present invention is to provide a multi-station variable-pitch manipulator to solve the problems in the above-mentioned background technology that each gripper corresponds to an independent drive unit, resulting in a large overall size and weight of the manipulator and a complex structure.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A multi-station variable-distance manipulator, comprising:

[0006] Support plate;

[0007] A driving mechanism, wherein the driving mechanism is arranged on the support plate;

[0008] a first displacement assembly, the first displacement assembly being disposed on the support plate and extending along a first direction; an output end of the driving mechanism being connected to the first displacement assembly so as to cause the output end of the first displacement assembly to reciprocate along the first direction;

[0009] a second displacement assembly, the second displacement assembly comprising a first slide rail, a plurality of slide rods, and a clamping claw provided on each of the slide rods; the first slide rail is provided on the support plate and extends along a second direction, the plurality of slide rods are installed on the first slide rail at intervals and can reciprocate along the second direction, the clamping claw is installed at an end of each of the slide rods, and the second direction is perpendicular to the first direction;

[0010] The pitch-variable plate includes a plurality of slide assemblies, the plurality of slide assemblies being spaced apart along the second direction. Along the first direction, each slide assembly has one end facing the clamping jaws as a first end and the other end as a second end. Furthermore, the spacing between the first ends of each adjacent slide assembly along the second direction is smaller than the spacing between the second ends thereof, or the spacing between the first ends of each adjacent slide assembly along the second direction is larger than the spacing between the second ends thereof. The slide rods are connected to the slide assemblies in a one-to-one correspondence. The output end of the first displacement assembly is connected to the pitch-variable plate to drive the pitch-variable plate to reciprocate along the first direction. Simultaneously, the slide rods reciprocate along the second direction under the push of the slide assemblies, thereby adjusting the spacing between the clamping jaws. With this arrangement, when the spacing between the first ends of the slide assemblies is smaller than the spacing between the second ends, the first ends of the slide assemblies are closer to each other in the second direction, while the second ends are farther away from each other in the second direction. When the spacing between the first ends of the slide assemblies is larger than the spacing between the second ends, the first ends of the slide assemblies are farther away from each other in the second direction, while the second ends of the slide assemblies are closer to each other in the second direction. When the pitch change plate moves back and forth in the first direction driven by the first displacement component, the slide groove component on the pitch change plate will apply a force in the second direction to the slide rod, causing it to move along the first slide rail, thereby causing the clamping claws at the end of the slide rod to move closer to or further away from each other, thereby realizing the variable pitch adjustment of the clamping claws.

[0011] Furthermore, the slide assembly includes a plurality of first slides and a plurality of connecting members; the extension direction of each first slide forms an angle with the first direction, and along the second direction, the angle between the extension direction of the first slide and the first direction gradually increases or decreases. Each first slide is connected to a corresponding slide rod via a connecting member. This arrangement enables the first slide to have a projected length along the first direction and also a projected length along the second direction. When the pitch variable plate reciprocates along the first direction, the slide rod connected to the first slide reciprocates along the second direction on the first slide rail under the force of the pitch variable plate, thereby adjusting the spacing between the clamping jaws.

[0012] Furthermore, the slide assembly includes a first slide, a second slide, and a connecting member; the first slide extends in a direction that forms an angle with the first direction, the second slide extends in a direction that is parallel to the first direction, the first slide is located on either side of the second slide and is symmetrically arranged relative to the center line of the second slide along the first direction, and the first slide and the second slide are both connected to corresponding slide rods via a connecting member. Through this arrangement, the first slide extends in a direction that forms an angle with the first direction, and the second slide extends in a direction that is parallel to the first direction, that is, the first slide has a projected length along the first direction and a projected length along the second direction, while the second slide has a projected length only along the second direction. The first slide is located on either side of the second slide, and when the pitch variable plate reciprocates in the first direction, the slide rod connected to the first slide reciprocates in the second direction on the first slide rail under the push of the pitch variable plate, while the slide rod connected to the second slide remains stationary. Similarly, the spacing between the clamping jaws can also be adjusted.

[0013] Furthermore, the connecting member includes a support column and a cam; the first end of the support column is fixed to the sliding rod, the cam is rotatably arranged at the second end of the support column, and the cam is located in the first sliding groove. When the pitch variable plate moves back and forth along the first direction, the cam rolls in the first sliding groove, thereby causing the support column to drive the sliding rod to move back and forth along the second direction.

[0014] Furthermore, the first displacement assembly includes a screw module; the screw module includes a screw and a connecting block; the screw extends in a first direction and is rotatably mounted on the support plate about its own axis; the connecting block is threadedly connected to the screw, and the pitch-variable plate is connected to the connecting block. The screw module has a simple structure and is low in weight, and can drive the pitch-variable plate to reciprocate in the first direction.

[0015] Furthermore, the first displacement assembly further includes a sliding module; the sliding module includes a second slide rail and a slider; the second slide rail is disposed on the support plate and extends along the first direction; one end surface of the slider is slidably disposed on the second slide rail, and the other end surface of the slider is connected to the pitch-variable plate. The provision of the sliding module can improve the stability of the pitch-variable plate during movement.

[0016] Furthermore, the driving mechanism includes a motor and a transmission member, and the output shaft of the motor is connected to the screw rod in the first displacement assembly through the transmission member.

[0017] Furthermore, the invention further comprises a first pulley, a second pulley, and a fixed plate; the fixed plate is mounted on the support plate, and both ends of the screw rod are rotatably mounted on the fixed plate. The output shaft of the motor is connected to the first pulley, and one end of the screw rod is connected to the second pulley. The transmission member is a synchronous belt, which connects the first pulley and the second pulley. With this arrangement, the motor drives the screw rod to rotate via the synchronous belt, so that the pitch-variable plate can generate displacement in the first direction.

[0018] Furthermore, it also includes an adapter seat, which is arranged at the end of each of the sliding rods. The clamping jaw is connected to the sliding rod through the adapter seat to keep the clamping jaw away from the support plate and the pitch change plate, thereby preventing the support plate and the pitch change plate from affecting the operation of the clamping jaw.

[0019] Furthermore, the adapter seat includes a first side plate, a second side plate and a bottom plate; the first side plate and the second side plate are arranged opposite to each other, one end of the bottom plate is connected to the first side plate, and the other end is connected to the second side plate, the first side plate is arranged at the end of the sliding rod, and the second side plate is used to install the clamp.

[0020] The utility model has the following advantages over the prior art:

Along the first direction, one end of each slide slot assembly facing the clamping claw is a first end, and the other end is a second end, and the spacing between the first ends of each adjacent two slide slot assemblies along the second direction is smaller than the spacing between their second ends along the second direction (i.e., the slide slots are arranged on the first end of the first end of the second ... first end of the second end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the first end of the second end of the first end of the first end of the second end of the first end of the first end of the first end of the second end of the first end of the first end of the first end of the second end of the first end of the second end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of the first end of The first ends of the components are close to each other, and the second ends thereof are far away from each other), or the spacing between the first ends of each adjacent two slide assemblies along the second direction is greater than the spacing between the second ends thereof along the second direction (that is, the first ends of the slide assemblies are far away from each other, and the second ends thereof are close to each other), and the slide rods are connected one-to-one with the slide assemblies; when the output end of the first displacement assembly drives the pitch-changing plate to move back and forth along the first direction, the slide assemblies will apply a force along the second direction to the corresponding slide rods, so that the slide rods can move along the first slide rail, so that the clamping jaws on each slide rod are close to or away from each other, thereby realizing the variable distance adjustment between each clamping jaw. The utility model only requires one driving mechanism, and the spacing adjustment between each clamping jaw can be realized under the cooperation of the driving mechanism with the first displacement assembly, the second displacement assembly and the pitch-changing plate. The structure is simple and reasonable, the manufacturing and use costs are low, and good economic benefits can be achieved.

[0022] 2. The specific arrangement of the chute assembly of the multi-station variable-pitch manipulator of the present invention is not limited. For example, the chute assembly includes a plurality of first chute assemblies and a plurality of connecting members. The extension direction of each first chute forms an angle with the first direction, and along the second direction, the angle between the extension direction of the first chute and the first direction gradually increases or decreases. The first chute is connected to the slide rod via the connecting member in the same manner. With this arrangement, the first chute has a projected length along the first direction and a projected length along the second direction. When the pitch-variable plate reciprocates along the first direction, the slide rod connected to the first chute reciprocates along the second direction on the first slide rail under the propulsion of the pitch-variable plate, thereby adjusting the spacing between the grippers. In addition, the chute assembly includes a first chute, a second chute, and a connecting piece, wherein the extension direction of the first chute is at an angle to the first direction, and the extension direction of the second chute is parallel to the first direction, that is, the first chute has a projected length along the first direction and also has a projected length along the second direction, and the second chute only has a projected length along the second direction, the first chute is distributed on both sides of the second chute, and the first chute and the second chute are both connected to the corresponding slide rods through the connecting piece. When the pitch variable plate moves back and forth along the first direction, the slide rod connected to the first chute moves back and forth along the second direction on the first slide rail under the push of the pitch variable plate, while the slide rod connected to the second chute remains stationary. This arrangement can also adjust the spacing between the clamping jaws. It can be seen that the chute assembly in the utility model can be flexibly arranged according to the on-site conditions and has extremely high market application prospects.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that, in the description of the present invention, the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0029] In addition, it should be understood that for the convenience of description, the sizes of the various components shown in the drawings are not drawn according to the actual scale.

[0030] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0031] Example 1:

[0032] like Figures 1 to 3 As shown, the utility model provides a multi-station variable-pitch manipulator, comprising: a support plate 1, a drive mechanism, a first displacement assembly, a second displacement assembly and a variable-pitch plate, wherein the support plate 1 is used to connect to the end of an external transfer device, so that the manipulator can achieve overall spatial movement.

[0033] The driving mechanism and the first displacement assembly are both mounted on the support plate 1. The first displacement assembly extends along the first direction (eg Figure 1 As shown, in this embodiment, the first direction is the vertical direction); the output end of the driving mechanism is connected to the first displacement component to drive the output end of the first displacement component to move back and forth along the first direction.

[0034] The second displacement assembly includes a first slide rail 2, a plurality of slide rods 3 and a clamping claw arranged on each of the slide rods 3; the first slide rail 2 is arranged on the support plate 1 and moves along the second direction (such as Figure 1As shown, the second direction in this embodiment is a horizontal direction perpendicular to the vertical direction), and multiple sliding rods 3 are installed on the first sliding rail 2 at intervals and can move back and forth along the second direction. The clamping claw 4 is installed at the end of each of the sliding rods 3; in order to improve the stability of the sliding process of the sliding rod 3, multiple groups of first sliding rails 2 are set in this embodiment, and the multiple groups of first sliding rails 2 all extend along the second direction and have intervals in the first direction.

[0035] The pitch-variable plate 5 includes a plurality of slide assemblies, which are spaced apart along the second direction. Along the first direction, each slide assembly has one end facing the clamping jaws 4 as a first end and the other end as a second end. Furthermore, the spacing between the first ends of each adjacent slide assembly along the second direction is smaller than the spacing between the second ends thereof, or the spacing between the first ends of each adjacent slide assembly along the second direction is larger than the spacing between the second ends thereof. The slide rods 3 are connected to the slide assemblies in a one-to-one correspondence. The output end of the first displacement assembly is connected to the pitch-variable plate 5 to drive the pitch-variable plate 5 to reciprocate along the first direction. Simultaneously, the slide rods 3 reciprocate along the second direction under the push of the slide assemblies, thereby adjusting the spacing between the clamping jaws. When the spacing between the first ends of the slide assemblies is smaller than the spacing between the second ends, the first ends of the slide assemblies are closer to each other in the second direction, while the second ends are farther away from each other in the second direction. When the spacing between the first ends of the slide assemblies is larger than the spacing between the second ends, the first ends of the slide assemblies are farther away from each other in the second direction, while the second ends are closer to each other in the second direction. With this arrangement, when the pitch-variable plate 5 reciprocates in the first direction driven by the first displacement assembly, the slideway assembly on the pitch-variable plate 5 applies a force in the second direction to the slide bar, causing it to move along the first slide rail, thereby moving the clamping jaws at the ends of the slide bar closer together or farther apart, achieving variable clamping jaw pitch adjustment. The multi-station variable-pitch manipulator in this embodiment requires only a single drive mechanism, which, through the cooperation of the drive mechanism with the first and second displacement assemblies and the pitch-variable plate, adjusts the spacing between the clamping jaws. This results in a simple and rational structure, low manufacturing and operating costs, and excellent economic benefits.

[0036] Preferably, if Figure 1-Figure 3As shown, the slide assembly includes a first slide 501, a second slide 502 and a connecting piece 503; the extension direction of the first slide 501 has an angle with the first direction, the extension direction of the second slide 502 is parallel to the first direction, the first slide 501 is distributed on both sides of the second slide 502, and is symmetrically arranged relative to the center line of the second slide 502 along the first direction, the first slide 501 and the second slide 502 are both connected to the corresponding slide rod 3 through a connecting piece, and the distance between the first ends of each adjacent two first slides 501 along the second direction is smaller than the distance between their second ends along the second direction, and the distance between the first end of the first slide 501 close to the second slide 502 and the second slide 502 along the second direction is smaller than the distance between their second ends along the second direction. Through this setting, the first slide groove 501 has a projected length along the first direction and a projected length along the second direction. The second slide groove 502 only has a projected length along the second direction. The first slide groove 501 is distributed on both sides of the second slide groove 502. When the pitch variable plate 5 moves back and forth along the first direction, the slide rod connected to the first slide groove 501 moves back and forth along the second direction on the first slide rail 2 under the push of the pitch variable plate 5, while the slide rod 3 connected to the second slide groove 501 remains stationary. Similarly, the spacing between each jaw can also be adjusted.

[0037] Preferably, the connecting member 503 includes a support column 504 and a cam 505. The first end of the support column 504 is fixed to the slide bar 3, and the cam 505 is rotatably mounted on the second end of the support column 504. The cam 505 is located in the first slide groove 2. When the pitch-changing plate 5 reciprocates in the first direction, the cam 505 rolls in the first slide groove 501, thereby causing the support column 504 to drive the slide bar 3 to reciprocate in the second direction. This arrangement cleverly utilizes the sliding cooperation between the cam and the slide groove to achieve variable pitch adjustment of the clamping jaws.

[0038] This embodiment also includes an adapter seat 15, which is arranged at the end of each of the slide rods 3. The clamping jaw 4 is connected to the slide rod 3 through the adapter seat 15 to keep the clamping jaw 4 away from the support plate 1 and the pitch change plate 5, so that the clamping jaw 4 has a larger working space, thereby preventing the support plate 1 and the pitch change plate 5 from affecting the operation of the clamping jaw.

[0039] Specifically, the adapter 15 includes a first side plate 1501, a second side plate 1502, and a bottom plate 1503. The first side plate 1501 and the second side plate 1502 are arranged opposite each other. One end of the bottom plate 1503 is connected to the first side plate 1501, and the other end is connected to the second side plate 1502. The first side plate 1501 is mounted on the end of the slide bar 3, and the second side plate 1502 is used to mount the clamping jaw 4. The adapter 15 has a simple structure and can move the clamping jaw 4 away from the support plate 1 and the pitch change plate 5, thereby providing a larger working space.

[0040] In this embodiment, the first displacement assembly includes a screw module; the screw module includes a screw 6 and a connecting block 7; the screw 6 extends in the first direction and is rotatably arranged on the support plate 1 around its own axis, the connecting block 7 is threadedly connected to the screw 6, and the pitch change plate 5 is connected to the connecting block. The screw module has a simple structure and is low in height, and can drive the pitch change plate to move back and forth along the first direction. The first displacement assembly also includes a sliding module; the sliding module includes a second slide rail 8 and a slider 9; the second slide rail 8 is arranged on the support plate 1 and extends in the first direction, one end face of the slider 9 is slidably arranged on the second slide rail 8, and the other end face of the slider 9 is connected to the pitch change plate 5. The stability of the movement process of the pitch change plate 5 can be improved by setting the sliding module. In this embodiment, the number of the second slide rails 8 is two, which are respectively located on both sides of the pitch change plate 5 to improve the sliding stability of the pitch change plate 5.

[0041] In this embodiment, the drive mechanism includes a motor 10, a transmission member, a first pulley 11, a second pulley 12, and a fixed plate 13. The fixed plate 13 is disposed on the support plate 1. Both ends of the screw rod 6 are rotatably disposed on the fixed plate 13. The output shaft of the motor 10 is connected to the first pulley 11, and one end of the screw rod 6 is connected to the second pulley 12. The transmission member is a synchronous belt 14, which connects the first pulley 11 and the second pulley 12. When the motor 10 is working, the synchronous belt 14 rotates, thereby rotating the screw rod 6 and causing the pitch variable plate 5 to reciprocate along the first direction.

[0042] When working specifically:

[0043] like Figure 1 As shown, in this embodiment, the spacing between the first ends of each adjacent two chute assemblies along the second direction is smaller than the spacing between their second ends along the second direction. The chute assembly includes a first chute 501, a second chute 502, and a connector 503. The extension direction of the first chute 501 forms an angle with the first direction, and the extension direction of the second chute 502 is parallel to the first direction. The first chute 501 is distributed on both sides of the second chute 502 and is symmetrically arranged relative to the center line of the second chute 502 along the first direction. The first chute 501 and the second chute 502 are both connected to the corresponding slide bar 3 via a connector.

[0044] The motor rotates, driving the synchronous belt 14, which in turn rotates the lead screw 6, causing the pitch plate 5 to reciprocate in the first direction. When the pitch plate 5 moves upward, the distance between the clamping jaws at the ends of the slide rod gradually decreases. When the pitch plate 5 moves downward, the distance between the clamping jaws at the ends of the slide rod gradually increases, thereby achieving variable pitch adjustment between the clamping jaws.

[0045] Example 2:

[0046] This embodiment is the same as embodiment 1 except for the following technical solutions:

[0047] In this embodiment, the slide assembly includes a plurality of first slides 501 and a plurality of connectors 503. Each first slide 501 extends in a direction that forms an angle with the first direction, and along the second direction, the angle between the extension direction of the first slide 501 and the first direction gradually increases or decreases. Each first slide 501 is connected to a corresponding slide bar 3 via a connector 503. This arrangement ensures that the first slide 501 has a projected length along the first direction and also a projected length along the second direction. When the pitch-variable plate 5 reciprocates in the first direction, the slide bar 3 connected to the first slide 501 reciprocates in the second direction on the first slide rail 2 under the force of the pitch-variable plate 5, thereby adjusting the spacing between the jaws.

[0048] In actual application, there is no restriction on the specific layout of the slide assembly, and it only needs to be ensured that: the spacing between the first ends of each adjacent two slide assemblies along the second direction is smaller than the spacing between their second ends along the second direction, or the spacing between the first ends of each adjacent two slide assemblies along the second direction is larger than the spacing between their second ends along the second direction. Because through this limitation "the first ends of the slide assemblies are close to each other in the second direction, and the second ends are far away from each other in the second direction" or "the first ends of the slide assemblies are far away from each other in the second direction, and the second ends are close to each other in the second direction", it can be ensured that when the variable pitch plate 5 moves back and forth in the first direction driven by the first displacement assembly, the slide assembly on the variable pitch plate 5 will apply a force in the second direction to the slide rod, causing it to move along the first slide rail, thereby making the clamping claws at the end of the slide rod approach or move away from each other, thereby realizing the variable pitch adjustment of the clamping claws.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
