Description

Technical Field

[0001] The present application relates to the field of transport equipment, and in particular to a transport mechanism. Background Art

[0002] In automated production processes, it is often necessary to use a transport mechanism to move workpieces. For example, two workpieces placed opposite each other must be moved from a first conveyor line to a second conveyor line that is perpendicular to the first, and the spacing between the two workpieces must also be adjusted.

[0003] In the prior art, two workpieces are generally rotated and transported to the target position by a transport mechanism, and then the distance between the two workpieces is adjusted. This processing method has the problem that the distance adjustment requires additional work cycle, which reduces the transport efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a transport mechanism, which adopts the following technical solutions:

[0005] A transport mechanism includes a base, a driving portion, a rotating plate, a first sliding seat, a second sliding seat, a first guide wheel, a second guide wheel, a first clamping assembly, and a second clamping assembly, wherein:

[0006] The driving part is arranged on the base, the lower surface of the base is provided with a first guide groove and a second guide groove, and the rotating plate is connected to the movable part of the driving part;

[0007] The rotating plate is provided with a slide rail;

[0008] The first sliding seat and the second sliding seat are both slidably connected to the slide rail, the first guide wheel is arranged on the first sliding seat and is located in the first guide groove, and the second guide wheel is arranged on the second sliding seat and is located in the second guide groove;

[0009] The first clamping assembly is connected to the first sliding seat, and the second clamping assembly is connected to the second sliding seat, and the first clamping assembly and the second clamping assembly are respectively used to clamp a workpiece;

[0010] The driving part is configured to drive the rotating plate to rotate, so as to drive the first clamping assembly and the second clamping assembly to rotate from the first position to the second position at the same time; during the rotation process, the rotating plate pushes the first guide wheel and the second guide wheel to slide in opposite directions along the first guide groove and the second guide groove, so as to drive the first sliding seat and the second sliding seat to slide together or slide apart along the slide rail.

[0011] The conveying mechanism provided by the present application has a driving portion that drives the first clamping assembly and the second clamping assembly to rotate from the first position to the second position by driving the rotating plate to rotate, thereby conveying the two workpieces clamped by the first clamping assembly and the second clamping assembly from the first position to the second position. In addition, during the rotation process, the rotating plate can push the first guide wheel and the second guide wheel to slide in opposite directions along the first guide groove and the second guide groove, thereby driving the first clamping assembly and the second clamping assembly to move closer or apart via the first sliding seat and the second sliding seat, so as to adjust the distance between the two workpieces during the conveying process. In other words, the conveying mechanism of the present application realizes the synchronous adjustment of the distance between the workpieces while conveying the two workpieces, thereby improving the conveying efficiency.

[0012] In some embodiments, a through hole is provided in the middle of the base, and the driving part includes a motor and a coupling, wherein: the motor is mounted on the base, the coupling is connected to the driving end of the motor and passes downward through the through hole, and the rotating plate is connected to the coupling.

[0013] The motor is connected to the rotating plate via a coupling, which can improve the driving stability of the rotating plate.

[0014] In some embodiments, the first guide groove comprises:

[0015] a first middle self-locking section located on a first side of a middle portion of the base;

[0016] A first end self-locking section is located on the third side of the middle portion of the base, the first end self-locking section is connected to the first middle self-locking section via the first variable distance section;

[0017] The second guide groove includes:

[0018] a second middle self-locking section located on a second side of the middle portion of the base, the second side being opposite to the first side;

[0019] a fourth end self-locking section located on a fourth side in the middle of the base, the fourth end self-locking section being connected to the second middle self-locking section via a fourth variable pitch section, the fourth side being opposite to the third side;

[0020] The distance between the first middle self-locking segment and the second middle self-locking segment is a first distance, and the distance between the first end self-locking segment and the fourth end self-locking segment is a second distance, and the second distance is greater than the first distance;

[0021] When the first clamping assembly and the second clamping assembly rotate from the first position to the second position along the first clockwise direction, the rotating plate pushes the first guide wheel from the first end self-locking section through the first pitch-changing section into the first middle self-locking section, and pushes the second guide wheel from the fourth end self-locking section through the second pitch-changing section into the second middle self-locking section;

[0022] When the first clamping assembly and the second clamping assembly rotate from the second position back to the first position along the second clockwise direction, the rotating plate pushes the first guide wheel from the first intermediate self-locking section through the first pitch changing section into the first end self-locking section, and pushes the second guide wheel from the second intermediate self-locking section through the second pitch changing section into the fourth end self-locking section.

[0023] By configuring the first and second guide grooves as described above, the transport mechanism of the present embodiment achieves synchronous adjustment of the spacing between the two workpieces during the transport process, causing the spacing between the two workpieces to gradually increase or decrease. Furthermore, after sliding into position, the first and second guide wheels are locked by the first and second guide grooves, respectively, to prevent accidental sliding of the first and second guide wheels when in position, which could cause a deviation in the spacing between the first and second clamping assemblies.

[0024] In some embodiments, the first guide groove further comprises:

[0025] A second end self-locking section is located on the fourth side of the middle portion of the base, the second end self-locking section is connected to the first middle self-locking section via the second variable pitch section;

[0026] The second guide groove also includes:

[0027] A third end self-locking section is located on a third side of the middle portion of the base, the third end self-locking section being connected to the second middle self-locking section via a third variable pitch section;

[0028] The distance between the second end self-locking section and the third end self-locking section is a second distance;

[0029] When the first clamping assembly and the second clamping assembly rotate from the second position back to the first position along the first clockwise direction, the rotating plate pushes the first guide wheel from the first intermediate self-locking section through the second pitch-changing section into the second end self-locking section, and the rotating plate pushes the second guide wheel from the second intermediate self-locking section through the third pitch-changing section into the third end self-locking section.

[0030] The relative positions of the first clamping assembly and the second clamping assembly are switched. For example, before the workpiece is moved, the first clamping assembly is located on the left side of the second clamping assembly. After the first clamping assembly and the second clamping assembly return to the second position, the first clamping assembly is adjusted to the right side of the second clamping assembly.

[0031] In some embodiments, the first middle self-locking segment, the second middle self-locking segment, the first end self-locking segment and the fourth end self-locking segment are all configured as arc-shaped grooves protruding outward from the base.

[0032] The first guide wheel and the second guide wheel can be locked by the arc groove after sliding into place, thereby preventing the first guide wheel and the second guide wheel from accidentally sliding when sliding into place.

[0033] In some embodiments, the first clamping assembly includes a first mounting base, a rotation drive assembly, and a first clamping member, wherein:

[0034] The first guide groove is located inside the second guide groove, and the distance between each section of the first guide groove and the center of the base is smaller than the distance between each section of the second guide groove and the center of the base;

[0035] The first mounting seat is fixedly connected to the rotating plate, and the first clamping member is rotatably connected to the first mounting seat;

[0036] The rotary drive assembly is at least partially disposed on the first mounting seat, is in transmission connection with the first clamping member, the first clamping member is used to clamp the workpiece, and is used to drive the first clamping member to rotate relative to the first mounting seat.

[0037] By setting up a rotary drive component, when the driving part drives the first clamping component and the second clamping component to rotate and transport the two clamped workpieces from the first position to the second position, the rotary drive component can drive the first clamping component to rotate relative to the first mounting seat, thereby adjusting the relative orientation of the first workpiece clamped by the first clamping component with respect to the second workpiece clamped by the second clamping component.

[0038] In some embodiments, the rotary drive assembly includes a rack and pinion, wherein:

[0039] The rack is arranged on the rotating plate;

[0040] The mounting shaft of the gear is rotatably mounted on the first mounting seat, the gear is meshed with the rack, and the first clamping member is connected to the lower end of the mounting shaft of the gear;

[0041] When the first guide wheel slides and switches between the first end self-locking section and the first middle self-locking section, or slides and switches between the second end self-locking section and the first middle self-locking section, the rack drives the gear to rotate, thereby driving the first clamping member to rotate relative to the first mounting seat.

[0042] By configuring the rotation drive assembly to include a rack and a gear, only one drive unit is required in the embodiment of the present application to complete the transportation of two workpieces and the adjustment of their relative orientations, thereby reducing equipment costs.

[0043] In some embodiments, the rotation drive assembly includes a rotation drive motor, which is disposed on the first mounting seat. The driving end of the rotation drive motor is connected to the first clamping member, and the rotation drive motor is used to drive the first clamping member to rotate relative to the first mounting seat.

[0044] A rotary drive motor independent of the drive unit is used as the rotary drive assembly, which improves the independence and flexibility of adjusting the relative orientation of the two workpieces and facilitates the installation and maintenance of the rotary drive assembly.

[0066] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0067] As described in the background art, conventional techniques generally involve rotating two workpieces to a target location using a transport mechanism, and then adjusting the distance between the two workpieces. This approach requires additional work cycles to adjust the distance, reducing transport efficiency.

[0068] In view of this, the present application provides a transport mechanism, which can achieve synchronous adjustment of the distance between workpieces during the transport of two workpieces, thereby improving the transport efficiency.

[0069] like Figures 1 to 3 As shown, the transport mechanism in the embodiment of the present application includes a base 1, a driving part 2, a rotating plate 3, a first sliding seat 4, a second sliding seat 5, a first guide wheel 6, a second guide wheel 7, a first clamping assembly 8 and a second clamping assembly 9, wherein:

[0070] The driving part 2 is provided on the base 1 . A first guide groove 100 and a second guide groove 200 are provided on the lower surface of the base 1 . The rotating plate 3 is connected to the movable component of the driving part 2 .

[0071] A slide rail 31 is provided on the rotating plate 3 .

[0072] The first sliding seat 4 and the second sliding seat 5 are both slidably connected to the slide rail 31 , the first guide wheel 6 is arranged on the first sliding seat 4 and located in the first guide groove 100 , and the second guide wheel 7 is arranged on the second sliding seat 5 and located in the second guide groove 200 .

[0073] The first clamping assembly 8 is connected to the first sliding seat 4 , and the second clamping assembly 9 is connected to the second sliding seat 5 . The first clamping assembly 8 and the second clamping assembly 9 are respectively used to clamp a workpiece.

[0074] The driving unit 2 is configured to rotate the rotating plate 3, thereby driving the first clamping assembly 8 and the second clamping assembly 9 to rotate simultaneously from the first position to the second position. During the rotation process, the rotating plate 3 pushes the first guide wheel 6 and the second guide wheel 7 to slide synchronously along the first guide groove 100 and the second guide groove 200 in opposite directions, thereby driving the first sliding seat 4 and the second sliding seat 5 to slide closer together or apart along the slide rail 31.

[0075] In the conveying mechanism in the embodiment of the present application, when the driving unit 2 drives the rotating plate 3 to rotate, it can drive the first clamping assembly 8 and the second clamping assembly 9 to rotate from the first position to the second position, thereby conveying the two workpieces clamped by the first clamping assembly 8 and the second clamping assembly 9 from the first position to the second position. In addition, during the rotation process, the rotating plate 3 can push the first guide wheel 6 and the second guide wheel 7 to slide in opposite directions along the first guide groove 100 and the second guide groove 200, thereby driving the first clamping assembly 8 and the second clamping assembly 9 to move closer or apart through the first sliding seat 4 and the second sliding seat 5, so as to adjust the distance between the two workpieces during the conveying process. It can be seen that the conveying mechanism in the embodiment of the present application realizes the synchronous adjustment of the distance between the two workpieces during the implementation of the conveying process of the two workpieces, thereby improving the conveying efficiency of the workpieces.

[0076] Optionally, a through-hole is provided in the middle of the base 1, and the drive unit 2 includes a motor 21 and a coupling 22, wherein: the motor 21 is mounted on the base 1, the coupling 22 is connected to the driving end of the motor 21 and extends downwardly through the through-hole, and the rotating plate 3 is connected to the coupling. The connection between the motor 21 and the rotating plate 3 via the coupling 22 can improve the driving stability of the rotating plate 3.

[0077] like Figure 3 As shown, the first guide groove 100 includes: a first middle self-locking section 101 located on a first side of the middle portion of the base 1. A first end self-locking section 102 located on a third side of the middle portion of the base 1, the first end self-locking section 102 communicating with the first middle self-locking section 101 via a first variable distance section 103. The second guide groove 200 includes: a second middle self-locking section 201 located on a second side of the middle portion of the base 1, the second side of the second side being opposite to the first side. A fourth end self-locking section 202 located on a fourth side of the middle portion of the base 1, the fourth end self-locking section 202 communicating with the second middle self-locking section 201 via a fourth variable distance section 203, the fourth side being opposite to the third side.

[0078] The distance between the first middle self-locking section 101 and the second middle self-locking section 201 is a first distance, and the distance between the first end self-locking section 102 and the fourth end self-locking section 202 is a second distance, which is greater than the first distance.

[0079] The process of transporting the workpiece by the transport mechanism in the embodiment of the present application is as follows:

[0080] Two workpieces to be transported are located at a first position and need to be transported to a second position, wherein an initial distance between the two workpieces at the first position is greater than a target distance between the two workpieces at the second position.

[0081] First, adjust the first guide wheel 6 to the first end self-locking section 102, and adjust the second guide wheel 7 to the fourth end self-locking section 202, so that the distance between the first clamping component 8 and the second clamping component 9 (i.e., the second distance) can match the initial distance between the two workpieces to be transported at the first position.

[0082] Next, the first clamping assembly 8 and the second clamping assembly 9 are controlled to clamp the two workpieces to be transported respectively.

[0083] Subsequently, the driving unit 2 drives the rotating plate 3 to rotate 90° in a first clockwise direction (e.g., clockwise), thereby causing the first clamping assembly 8 and the second clamping assembly 9 to rotate and transport the two clamped workpieces to the second position along the first clockwise direction. During this process, the rotating plate 3 pushes the first guide wheel 6 from the first end self-locking section 102 through the first variable pitch section 103 into the first intermediate self-locking section 101, and pushes the second guide wheel 7 from the fourth end self-locking section 202 through the fourth variable pitch section 203 into the second intermediate self-locking section 201. In this way, the distance between the first clamping assembly 8 and the second clamping assembly 9 can be reduced to the first distance, which matches the target distance between the two workpieces at the second position.

[0084] Finally, the first clamping assembly 8 and the second clamping assembly 9 are controlled to release the two workpieces to the second position.

[0085] At this point, the transport of the two workpieces is complete. At this point, the drive unit 2 can drive the rotating plate 3 to rotate 90° in the second clockwise direction (e.g., counterclockwise), thereby causing the first clamping assembly 8 and the second clamping assembly 9 to return to their first position along the second clockwise direction. In this return method, the relative positions of the first clamping assembly 8 and the second clamping assembly 9 remain unchanged. For example, before the workpieces are transported, the first clamping assembly 8 is located to the left of the second clamping assembly 9. After the first clamping assembly 8 and the second clamping assembly 9 return to their first position, the first clamping assembly 8 remains to the left of the second clamping assembly 9.

[0086] It can be seen that by configuring the first guide groove 100 and the second guide groove 200 as described above, the transport mechanism of the present embodiment can achieve synchronous adjustment of the spacing between the two workpieces during the transport process, thereby gradually increasing or decreasing the spacing between the two workpieces. In addition, the first guide wheel 6 and the second guide wheel 7 can be locked by the first guide groove 100 and the second guide groove 200 after sliding into place, preventing the first guide wheel 6 and the second guide wheel 7 from accidentally sliding when they are in place, which could cause a deviation in the spacing between the first clamping assembly 8 and the second clamping assembly 9.

[0087] Of course, the transport mechanism in the embodiment of the present application can also transport the two workpieces located at the second position to the first position, and adjust the distance between the two workpieces during the transport process to increase the distance between the two workpieces.

[0088] Optionally, the first middle self-locking section 101 , the second middle self-locking section 201 , the first end self-locking section 102 and the fourth end self-locking section 202 are all configured as arc-shaped grooves protruding outward from the base 1 .

[0089] This arrangement further ensures that the first guide wheel 6 and the second guide wheel 7 are locked by the first guide groove 100 and the second guide groove 200 after sliding into position, preventing the first guide wheel 6 and the second guide wheel 7 from accidentally sliding when sliding into position. It also prevents the first guide wheel 6 and the second guide wheel 7 from sliding on their own when the transport mechanism suddenly stops, causing the workpiece to shift in position.

[0090] Continue to refer Figure 3 As shown, the first guide groove 100 optionally further includes a second end self-locking section 104 located on the fourth side of the middle portion of the base 1. The second end self-locking section 104 communicates with the first middle self-locking section 101 via a second variable distance section 105. The second guide groove 100 further includes a third end self-locking section 204 located on the third side of the middle portion of the base 1. The third end self-locking section 204 communicates with the second middle self-locking section 201 via a third variable distance section 205. The spacing between the second end self-locking section 104 and the third end self-locking section 204 is a second spacing.

[0091] When the first clamping assembly 8 and the second clamping assembly 9 rotate from the second position back to the first position along the first clockwise direction, the rotating plate 3 pushes the first guide wheel 6 from the first intermediate self-locking section 101 through the second variable distance section 105 into the second end self-locking section 104, and the rotating plate 3 pushes the second guide wheel 7 from the second intermediate self-locking section 201 through the third variable distance section 205 into the third end self-locking section 204.

[0092] By sequentially providing the second variable distance section 105 and the second end self-locking section 104 at the end of the first intermediate self-locking section 101, and sequentially providing the third variable distance section 205 and the third end self-locking section 204 at the end of the second intermediate self-locking section 201, after the first clamping assembly 8 and the second clamping assembly 9 release the two workpieces to the second position, the driving unit 2 can drive the rotating plate 3 to continue rotating 90 degrees in the first clockwise direction, thereby returning the first clamping assembly 8 and the second clamping assembly 9 to the first position in the first clockwise direction.

[0093] The effect achieved by this return method is that the relative positions of the first clamping component 8 and the second clamping component 9 can be switched. For example, before the workpiece is transported, the first clamping component 8 is located on the left side of the second clamping component 9. After the first clamping component 8 and the second clamping component 9 return to the second position, the first clamping component 8 is adjusted to the right side of the second clamping component 9.

[0094] In some applications, in addition to moving two workpieces from a first position to a second position, the relative orientation of the two workpieces must also be adjusted. For example, the workpieces to be moved may have opposing first and second surfaces, each with different functional surfaces. In the first position, the first surface of the first workpiece faces the second surface of the second workpiece. After the workpiece is moved, the second surface of the first workpiece faces the second surface of the second workpiece. Therefore, the first workpiece must be rotated.

[0095] To solve this problem, Figure 1 and Figure 4 As shown, optionally, the first clamping assembly 8 includes a first mounting seat 81, a rotation drive assembly 82 and a first clamping member 83, wherein:

[0096] The first guide groove 100 is located inside the second guide groove 200 , and the distance between each section of the first guide groove 100 and the center of the base 1 is smaller than the distance between each section of the second guide groove 200 and the center of the base 1 .

[0097] The first mounting seat 81 is fixedly connected to the rotating plate 3, and the first clamping member 83 is rotatably connected to the first mounting seat 81. The rotation drive assembly 82 is at least partially disposed on the first mounting seat 81 and is in transmission connection with the first clamping member 83. The first clamping member 83 is used to clamp a workpiece, and the rotation drive assembly 82 is used to drive the first clamping member 83 to rotate relative to the first mounting seat 81.

[0098] By setting up a rotary drive component 82, when the driving part 2 drives the first clamping component 8 and the second clamping component 9 to rotate and transport the two clamped workpieces from the first position to the second position, the rotary drive component 82 can drive the first clamping member 83 to rotate relative to the first mounting seat 81, thereby adjusting the relative orientation of the first workpiece clamped by the first clamping component 8 with respect to the second workpiece clamped by the second clamping component 9.

[0099] As mentioned in the previous embodiment, if the first clamping assembly 8 and the second clamping assembly 9 return to the first position along the second clockwise direction, the relative positions of the first clamping assembly 8 and the second clamping assembly 9 remain unchanged. Thus, after the first clamping assembly 8 and the second clamping assembly 9 return to the first position, the first clamping assembly 8 continues to carry and rotate the first workpiece in the next group of workpieces, while the second clamping assembly 9 continues to carry the second workpiece in the next group of workpieces.

[0100] If the first clamping assembly 8 and the second clamping assembly 9 return to the first position along the first clockwise direction, the relative orientation of the first clamping assembly 8 and the second clamping assembly 9 switches. Thus, after the first clamping assembly 8 and the second clamping assembly 9 return to the first position, the first clamping assembly 8 carries and rotates the second workpiece in the next group of workpieces, while the second clamping assembly 9 carries the first workpiece in the next group of workpieces. This allows the transport mechanism of the present embodiment to meet various transport requirements and improve compatibility.

[0101] Optional, such as Figure 1 As shown, the rotation drive assembly 82 includes a rack 821 and a gear 822, wherein the rack 821 is provided on the rotating plate 3. The mounting shaft of the gear 822 is rotatably mounted on the first mounting seat 81, the gear 822 meshes with the rack 821, and the first clamping member 83 is connected to the lower end of the mounting shaft of the gear 822.

[0102] When the first guide wheel 6 slides and switches between the first end self-locking section 102 and the first middle self-locking section 101, or slides and switches between the second end self-locking section 104 and the first middle self-locking section 101, the rack 821 drives the gear 822 to rotate, thereby driving the first clamping member 83 to rotate relative to the first mounting seat 81.

[0103] It can be seen that when the driving unit 2 drives the rotating plate 3 to rotate 90° in the first clockwise direction (e.g., clockwise), so that the first clamping assembly 8 and the second clamping assembly 9 rotate and transport the two clamped workpieces to the second position along the first clockwise direction, the rotation driving assembly 82, driven by the rotating plate 3, automatically adjusts the relative orientation of the workpiece clamped by the first clamping assembly 8 with respect to the second workpiece clamped by the second clamping assembly 9. In other words, by configuring the rotation driving assembly 82 to include a rack 821 and a gear 822, only one driving unit 2 is required in the embodiment of the present application to complete the transportation of the two workpieces and the adjustment of their relative orientation, thereby reducing equipment costs.

[0104] Of course, in other embodiments, a rotation drive device independent of the drive unit 2 may be provided to drive the first clamping member to rotate relative to the first mounting seat, thereby rotating the workpiece clamped by the first clamping assembly 8. For example, the rotation drive assembly 82 includes a rotation drive motor, which is disposed on the first mounting seat 81. The drive end of the rotation drive motor is connected to the first clamping member 83, and the rotation drive motor is used to drive the first clamping member 83 to rotate relative to the first mounting seat 81.
