Description
Technical Field
[0001] The utility model relates to the technical field of automatic production, in particular to a carrier transfer mechanism and a plate-passing production line. Background Art
[0002] In traditional automatic production, in order to support workpieces, carriers are often arranged on the production line. Driven by the production line, the carriers pass through multiple workstations in sequence, so as to process the workpieces on the carriers.
[0003] However, the workpieces on the carrier can only flow into the next workstation after the operation at one workstation is completed. This leads to the situation that when a workstation has received a carrier, the carriers before this workstation cannot continue to flow, affecting the processing efficiency of automatic production. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a carrier transfer mechanism and a plate-passing production line to solve the problem that when a workstation has received a carrier, the carriers on the previous workstations cannot continue to flow.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions:
[0006] In a first aspect, the utility model provides a carrier transfer mechanism, which includes a lifting assembly, a lifting limit member and a clamping assembly. The lifting assembly is configured to lift the carrier upward; the lifting limit member is arranged above the lifting assembly and is configured to limit the lifting height of the carrier, and the carrier located on the lifting assembly can abut against the lifting limit member; the clamping assembly includes two jaws symmetrically arranged on both sides of the lifting assembly along a horizontal first direction, and a first driving member connected to the jaws. The first driving member is configured to drive the two jaws to move towards or away from each other along the first direction. The jaws have a supporting surface for supporting the carrier and a clamping surface for clamping the carrier along the first direction.
[0007] Optionally, the lifting assembly includes a second driving member and a lifting plate. A positioning pin extending upward is arranged on the lifting plate, and the second driving member is arranged below the lifting plate to drive the lifting plate to move up and down.
[0008] Optionally, the lifting assembly further includes a first guiding member, a second guiding member and a lifting mounting seat. The second driving member and the first guiding member are both arranged on the lifting mounting seat. The second guiding member is fixed on the lifting plate. One of the first guiding member and the second guiding member is a linear bearing, and the other is a guiding shaft. The guiding shaft is slidably arranged in the linear bearing.
[0009] Optionally, the jaw further includes a guiding surface, which is disposed on a side of the jaw facing another jaw in the clamping assembly, and the guiding surface gradually moves away from the other jaw in the clamping assembly from bottom to top.
[0010] Optionally, the lifting limiting member includes two groups of limiting block groups symmetrically arranged along the first direction. Each limiting block group includes at least two limiting blocks spaced apart along the second direction, and the lower surface of the limiting block can abut against the carrier. The second direction is a horizontal direction perpendicular to the first direction.
[0011] Optionally, the clamping assembly further includes a first monitoring member communicatively connected to the first driving member, and the first monitoring member is used to monitor whether the carrier is in a preset position along the first direction.
[0012] In a second aspect, the present utility model provides a plate-passing production line, which includes a conveying line and the carrier transfer mechanism described above. The conveying line can convey the carrier along the second direction, and there are two conveying lines spaced apart along the first direction. The lifting assembly is disposed between the two conveying lines, two jaws of the clamping assembly are respectively fixed to the two conveying lines, and the lifting limiting member is also fixed to the conveying line.

[0014] Optionally, the plate-passing production line further includes a check mechanism disposed between the two conveying lines, and the check mechanism is used to block the carrier from moving upstream along the conveying line.
[0015] Optionally, the plate-passing production line further includes a blocking mechanism disposed between the two conveying lines. The blocking mechanism includes a fourth driving member and a blocking member, and the fourth driving member is disposed below the blocking member to drive the blocking member to move up and down.
[0016] Advantages of the present utility model:
[0017] In the carrier transfer mechanism and the plate-passing production line provided by the present utility model, the lifting assembly can lift the carrier upward, so that the carrier is separated from the conveying line. During the lifting process, the carrier abuts against the lifting limiting member, and the lifting assembly stops lifting the carrier.

[0034] Reference Figures 1-5 As shown, in the embodiment of the present utility model, a vehicle transfer mechanism is proposed, which includes a lifting assembly 1, a lifting limit member 2, and a clamping assembly 3. The lifting assembly 1 is configured to lift the vehicle 10 upward. The lifting limit member 2 is arranged above the lifting assembly 1 and is configured to limit the lifting height of the vehicle 10. The vehicle 10 located on the lifting assembly 1 can abut against the lifting limit member 2. The clamping assembly 3 includes two jaws 32 symmetrically arranged on opposite sides of the lifting assembly 1 along the horizontal first direction ( Figure 1 the X direction in
[0035] The above vehicle transfer mechanism can use the lifting component 1 to lift the vehicle 10 upward, so that the vehicle 10 is separated from the transmission structure and the conveyor line of the assembly line. During the lifting process, the vehicle 10 abuts against the lifting limit member 2, and the lifting component 1 stops lifting the vehicle 10. Then, the clamping component 3 is used to clamp and fix the vehicle 10. At this time, the lifting component 1 retracts, and the space between the vehicle 10 and the lifting component 1 allows other vehicles 10 to flow normally without affecting the use of other workstations.
[0036] Reference Figure 2 and Figure 4 As shown, the lifting component 1 includes a second driving member 11 and a lifting plate 12. The lifting plate 12 is used to place the vehicle 10. The second driving member 11 is arranged below the lifting plate 12 and connected to the lifting plate 12 to drive the lifting plate 12 to move up and down.
[0037] Specifically, in order to prevent the vehicle 10 from shifting relative to the lifting plate 12, positioning pins 121 that are inserted and matched with the positioning holes on the vehicle 10 are arranged on the lifting plate 12. The positioning pins 121 extend upward to pass through the positioning holes from bottom to top.
[0038] Continue to refer to Figure 4 As shown, the lifting component 1 further includes a first guiding member 13, a second guiding member 14, and a lifting mounting seat 15. The lifting mounting seat 15 is used to fix the second driving member 11 and the first guiding member 13 on the conveyor line, and the second guiding member 14 is fixed on the lifting plate 12.
[0039] Exemplarily, one of the first guiding member 13 and the second guiding member 14 is a linear bearing, and the other is a guiding shaft. The guiding shaft is slidably arranged in the linear bearing.
[0040] In order to limit the driving lifting height of the second driving member 11, the lifting component 1 further includes a trigger member 17 and a sensing member 16 that are communicatively connected to the second driving member 11. One of the trigger member 17 and the sensing member 16 is arranged on the lifting plate 12, and the other is arranged on the lifting mounting seat 15. When the sensing member 16 senses the trigger member 17, the second driving member 11 stops operating. Specifically, two sensing members 16 are arranged in the vertical direction to respectively limit the rising height and the falling height of the second driving member 11.
[0041] Exemplarily, the trigger member 17 is arranged on the lower surface of the lifting plate 12, and the sensing member 16 is arranged on the lifting mounting seat 15. The trigger member 17 uses a trigger piece, and the sensing member 16 uses a laser pair switch. During the movement of the trigger member 17 along with the lifting plate 12, it can be inserted between the transmitting end and the receiving end of the laser pair switch to form an induction signal.
[0042] Optionally, both the second driving member 11 and the first driving member 31 are cylinders, and the first driving member 31 includes two cylinders symmetrically arranged along the first direction, so that the two clamping jaws 32 move towards or away from each other. In other embodiments, the second driving member 11 and the first driving member 31 may also adopt linear driving structures such as electric cylinders.
[0043] Refer to Figure 5 As shown, the clamping jaw 32 further includes a guiding surface 3213. The guiding surface 3213 is arranged on the side of the clamping jaw 32 facing the other clamping jaw 32 in the clamping assembly 3, and the guiding surface 3213 gradually moves away from the other clamping jaw 32 in the clamping assembly 3 from bottom to top. The setting of the guiding surface 3213 can reduce the difficulty of the clamping jaw 32 moving below the carrier 10, improve the clamping force of the clamping surface 3212 and the lifting limiting member 2 on the carrier 10 in the up and down direction, and make the clamping more stable.
[0044] Specifically, the clamping assembly 3 further includes a connecting seat 33. The first driving member 31 is arranged on the connecting seat 33. The clamping jaw 32 includes a clamping block 321 and a clamping mounting seat 322. The clamping mounting seat 322 is fixed to the output end of the first driving member 31, and the clamping mounting seat 322 includes two mounting portions 3221 spaced along the second direction ( Figure 1 the Y direction in the figure). The two L-shaped clamping blocks 321 are respectively mounted on the two mounting portions 3221. The supporting surface 3211, the clamping surface 3212 and the guiding surface 3213 are all arranged on the clamping block 321. The second direction is the horizontal direction perpendicular to the first direction.
[0045] The clamping assembly 3 further includes a first monitoring member communicatively connected to the first driving member 31. The first monitoring member is used to monitor whether the carrier 10 is in a preset position along the first direction. Exemplarily, the first monitoring member adopts a distance sensor, and two first monitoring members are symmetrically arranged along the first direction. When the first monitoring member detects that the carrier 10 is in the preset position along the first direction, the first driving member 31 stops operating.
[0046] Continue to refer to Figures 1-3 As shown, the lifting limiting member 2 includes two groups of limiting block groups symmetrically arranged along the first direction. The limiting block groups are fixed on the connecting seat 33, and each limiting block group includes at least two limiting blocks 21 spaced along the second direction. The lower surface of the limiting block 21 can abut against the upper end surface of the carrier 10, so as to realize the upward limit of the carrier 10 in the vertical direction.
[0047] Refer to Figures 6-9As shown, in an embodiment of the present utility model, a through-board assembly line is further proposed, which includes two conveyor lines 4 arranged at intervals in the first direction. The two conveyor lines 4 can transport the carrier 10 in the second direction, so that the carrier 10 can be transferred between different workstations. The through-board assembly line further includes the carrier transfer mechanism in any of the above embodiments. The lifting assembly 1 is arranged between the two conveyor lines 4, the clamping assembly 3 is fixed to the two conveyor lines 4 through the connecting seat 33, and the lifting limit member 2 is also fixed to the conveyor line 4 through the connecting seat 33. According to the different numbers of workstations corresponding to the conveyor line 4, multiple carrier transfer mechanisms can be arranged at intervals in the second direction.
[0048] Optionally, in order to make the distance between the carrier 10 on the lifting assembly 1 and the conveyor lines 4 on both sides the same, the lifting assembly 1 is arranged centrally relative to the two conveyor lines 4.
[0049] Optionally, the distance between the two conveyor lines 4 in the first direction is adjustable for transporting carriers 10 of different sizes. Specifically, the through-board assembly line further includes a base 5. At least two bases 5 are arranged at intervals in the second direction below the conveyor lines 4, and at least one of the two conveyor lines 4 is slidably connected to the base 5 in the first direction. By adjusting the position of the conveyor line 4 on the base 5, the adjustment of the distance between the two conveyor lines 4 in the first direction can be achieved.
[0050] In order to make the lifting assembly 1 always arranged centrally relative to the two conveyor lines 4, the lifting assembly 1 is slidably arranged on the base 5 in the first direction through the lifting mounting seat 15.
[0051] In one embodiment, the conveyor line 4 is a pulley conveyor line or a sprocket conveyor line. In order to reduce the production cost of automation, a linkage shaft 8 is connected between the drive wheels of the two conveyor lines 4 to rotate synchronously under the drive of the same third drive member 9. Specifically, a chute extending in the first direction is provided on the linkage shaft 8, and a sliding pin is provided on the axle of at least one of the drive wheels connected to the linkage shaft 8. The sliding pin can be inserted into the chute and move in the chute in the first direction, so as not to affect the synchronous rotation of the drive wheels with the linkage shaft 8 on the basis of adjusting the distance between the two conveyor lines 4.
[0052] Reference Figure 6As shown, the board-passing assembly line further includes a blocking mechanism 7 and a check mechanism 6. The blocking mechanism 7 and the check mechanism 6 are both arranged between the two conveyor lines 4, and multiple groups of the blocking mechanism 7 and the check mechanism 6 can be arranged according to the number of workstations corresponding to the board-passing assembly line. The blocking mechanism 7 is used to block the carrier 10 from moving downstream along the conveyor line 4, while the check mechanism 6 is used to block the carrier 10 from moving upstream along the conveyor line 4. The blocking mechanism 7 and the check mechanism 6 cooperate with each other to keep the carrier 10 staying at the current workstation, improving the stability during the processing of the workpiece on the carrier 10. It can be understood that, in the direction of the conveyor line 4 transporting the carrier, the position passed first is the upstream, and the position passed later is the downstream.
[0053] Specifically, referring to Figure 7 and Figure 8 As shown, the check mechanism 6 includes a check block 61, a check mounting seat 63, and an elastic member 62. The first end of the check block 61 is hinged to the check mounting seat 63 through a hinge shaft. The check block 61 has a check surface 611 that slopes upward from the upstream to the downstream of the conveyor line 4. The elastic member 62 is arranged at the second end of the check block 61 and below the check block 61 to provide an upward elastic force to the check block 61. When the carrier 10 moves to contact the check surface 611 driven by the conveyor line 4, a downward force is applied to the check surface 611, and the carrier 10 crosses the check mechanism 6 and continues to move downstream. Subsequently, the check block 61 is reset by the elastic member 62. When the carrier 10 has a tendency to move upstream along the conveyor line 4 under an external force, for example, the force applied by the workstation to the workpiece, the check block 61 blocks the movement of the carrier 10.
[0054] Referring to Figure 9 As shown, the blocking mechanism 7 includes a fourth driving member 71 and a blocking member 72. The fourth driving member 71 is arranged below the blocking member 72 and connected to the blocking member 72 to drive the blocking member 72 to move up and down. When the blocking member 72 rises to a height higher than the height of the carrier 10, the carrier 10 can be blocked from continuing to move in the direction of the next workstation.
[0055] Exemplarily, the fourth driving member 71 is a cylinder.
[0056] The board-passing assembly line further includes a second monitoring member for monitoring whether the carrier 10 is at a preset position along the second direction of the conveyor line 4. Exemplarily, the second monitoring member is a photoelectric pair-switch.
[0057] When the above board-passing assembly line is in use, the lifting assembly lifts the carrier, separating the carrier from the conveyor line until the carrier abuts against the lifting limit member. The first driving member in the clamping assembly drives the jaws to clamp and fix the carrier, and the lifting assembly descends. Another carrier located upstream of this carrier passes through the carrier fixed on the clamping assembly and flows to the next workstation.
[0058] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
