Description

Technical Field

[0001] This utility model belongs to the field of transfer devices, and specifically relates to a material unloading trolley. Background Technology

[0002] With rapid economic development and continuous social progress, people's living standards are getting better and better, and automobiles have become an indispensable tool in people's lives. During automobile manufacturing, vehicles need to be transferred between different workstations to complete different processes. Therefore, material handling trolleys are needed for this transfer and coordination.

[0003] The existing unloading trolley has a simple structure and cannot be compatible with multiple models. Each time the model is switched, the corresponding transfer trolley needs to be imported, which is cumbersome. Unused trolleys require additional parking space, resulting in a waste of space in the workshop. Utility Model Content

[0004] In view of the above problems, this application provides a material unloading trolley that can increase the compatible vehicle models of the material unloading trolley and improve its adaptability.

[0005] This application provides a material unloading trolley, which includes a body, a support block, and a positioning pin assembly. The body has a mounting surface; the support block is disposed on the mounting surface and is used to support body-in-white parts; the positioning pin assembly includes a first positioning pin assembly and a second positioning pin assembly spaced apart along a first direction on the mounting surface, the first positioning pin assembly and the second positioning pin assembly being respectively used to insert into positioning holes of the body-in-white parts, the first direction being perpendicular to the direction of gravity; wherein, at least one of the first positioning pin assembly and the second positioning pin assembly is adjustablely disposed on the mounting surface along the first direction.

[0006] In the above technical solution, by setting one of the first positioning pin assembly and the second positioning pin assembly to be adjustable along the first direction on the mounting surface, the first positioning pin assembly and the second positioning pin assembly can be adapted to different body-in-whites with different positioning hole distances. This allows the unloading trolley to fix and transport different models of body-in-whites. This expands the applicability of the unloading trolley and reduces the risk of wasted workshop space caused by unused unloading trolleys.

[0007] In some embodiments, the unloading trolley further includes a mounting member and a guide rail. The mounting member is disposed on the mounting surface; the guide rail is disposed on the side of the mounting member opposite to the mounting surface and extends along a first direction, and a first mounting seat of the first positioning pin assembly is slidably disposed on the guide rail.

[0008] In the above technical solution, by slidably setting the first mounting seat of the first positioning pin assembly on the guide rail, on the one hand, the first mounting seat of the first positioning pin assembly can move more stably along the first direction, improving the reliability of the unloading trolley positioning; on the other hand, it reduces the risk that the first positioning pin assembly and the second positioning pin assembly will fail to limit the body-in-white part due to the first positioning pin assembly deviating in the second direction when moving along the first direction, which would prevent the first positioning pin assembly and the second positioning pin assembly from being inserted into the corresponding positioning hole of the body-in-white part.

[0009] In some embodiments, the unloading trolley further includes a locking pin. The locking pin is adjustable along the direction of gravity and is disposed on the first mounting base; the mounting member is provided with a first limiting hole corresponding to the locking pin on the side opposite to the mounting surface, and there are a plurality of first limiting holes spaced apart along the first direction. One end of the locking pin is inserted into the first limiting hole to fix the first mounting base relative to the guide rail.

[0010] In the above technical solution, by inserting one end of the locking pin into different first limiting holes, the first mounting seat is fixed relative to the second positioning pin assembly at different positions, thereby enabling the first positioning pin assembly and the second positioning pin assembly to limit different models of body-in-white parts. The structure is simple and easy to implement.

[0011] In some embodiments, the locating pin assembly includes a mounting base, a connector, a locating pin, and a first washer. The mounting base is disposed on the mounting surface; the connector is detachably mounted on the side of the mounting base away from the mounting surface along the direction of gravity; the locating pin is disposed on the connector; and the first washer is clamped between the connector and the mounting base along the direction of gravity.

[0012] In the above technical solution, by clamping the first shim between the connector and the mounting base along the direction of gravity, the position of the positioning pin in the direction of gravity is adjusted so that the positioning pin can be better inserted into the positioning hole of the body-in-white part, thereby increasing the stability of the unloading trolley in fixing the body-in-white part.

[0013] In some embodiments, the positioning pin assembly further includes a first abutment, a second washer, a third washer, and a first abutment. The first abutment is disposed on the mounting base and located on one side of the connector in the first direction; the second washer is sandwiched between the connector and the first abutment along the first direction; the second abutment is disposed on the mounting base and located on one side of the connector in the second direction, wherein the first direction, the second direction, and the gravity direction are mutually perpendicular; the third washer is sandwiched between the connector and the second abutment along the second direction.

[0014] In the above technical solution, by clamping the second shim between the connector and the first abutment in the first direction and by clamping the third shim between the connector and the second abutment in the second direction, the position of the positioning pin in the second direction and the first direction is adjusted so that the positioning pin can be better inserted into the positioning hole of the body-in-white part, thereby increasing the stability of the unloading trolley in fixing the body-in-white part.

[0015] In some embodiments, the unloading trolley further includes a snap-fit ​​mechanism disposed on the mounting surface, and the support block snaps into the snap-fit ​​mechanism.

[0016] In the above technical solution, by engaging the support block with the engagement mechanism, the support block is detachably connected to the car body. This facilitates the replacement of different support blocks for different body-in-white parts, enabling the unloading trolley to fix and transport different models of body-in-white. This further expands the applicability of the unloading trolley and reduces the risk of wasted workshop space due to unused unloading trolleys.

[0017] In some embodiments, the snap-fit ​​mechanism includes a mounting tube and a snap fastener. The mounting tube is disposed on the mounting surface and has a first end and a second end, the second end being located above the first end; the snap fastener is rotatably disposed on the first end along a rotation axis perpendicular to the direction of gravity; wherein the support block has an insertion end for inserting into the second end, and the periphery of the insertion end is provided with a slot adapted to the snap fastener.

[0018] In the above technical solution, after the insertion end is inserted into the second end, the slot and buckle on the periphery of the insertion end are engaged to prevent the insertion end from detaching from the mounting tube. At the same time, the second end is located above the first end, so that when the support block carries the body-in-white parts, the pressure of the body-in-white parts can drive the insertion end to move towards the first end, further reducing the risk of the insertion end detaching from the mounting tube and improving the reliability of the unloading trolley during use.

[0019] In some embodiments, the snap-fit ​​mechanism further includes a first elastic element disposed within the mounting tube and used to provide an elastic force to the buckle so that the buckle snaps into the slot.

[0020] In the above technical solution, the first elastic element drives the buckle to engage with the slot. The structure is simple and easy to implement.

[0021] In some embodiments, a second limiting hole communicating with the interior of the mounting tube is provided on the side wall of the mounting tube, and a third limiting hole is provided on the periphery of the insertion end. The buckle engages with the slot so that the second limiting hole aligns with the third limiting hole. The engaging mechanism further includes a plug pin, which passes through the second limiting hole and the third limiting hole in sequence to fix the insertion end relative to the mounting tube.

[0022] In the above technical solution, by passing the insertion pin through the second limiting hole and the third limiting hole in sequence to fix the insertion end relative to the mounting tube, the risk of the insertion end detaching from the mounting tube is further reduced, and the reliability of the unloading trolley during use is further improved.

[0023] In some embodiments, the unloading trolley further includes a locking structure, which is telescopically disposed on the side of the vehicle body facing the ground along the direction of gravity. One end of the locking structure extends relative to the vehicle body and is inserted into a fourth limiting hole on the ground to fix the vehicle body relative to the ground.

[0024] In the above technical solution, by extending one end of the locking structure relative to the car body and inserting it into the fourth limiting hole on the ground, the car body is fixed relative to the ground, which makes it easier for the unloading trolley to be fixed at the unloading station, thereby reducing the risk of the car body parts falling and being damaged due to the movement of the trolley during the unloading process.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] With rapid economic development and continuous social progress, people's living standards are getting better and better, and automobiles have become an indispensable tool in people's lives. During automobile manufacturing, vehicles need to be transferred between different workstations to complete different processes. Therefore, material handling trolleys are needed for this transfer and coordination.

[0039] The existing unloading trolley has a simple structure and cannot be compatible with multiple models. Each time the model is switched, the corresponding transfer trolley needs to be imported, which is cumbersome. Unused trolleys require additional parking space, resulting in a waste of space in the workshop.

[0040] To solve the above technical problems, refer to Figure 1 and Figure 2 This application provides a material unloading trolley including a body 10, a support block 20, and a positioning pin assembly 30. The body 10 has a mounting surface 101; the support block 20 is disposed on the mounting surface 101 and is used to support body-in-white parts; the positioning pin assembly 30 includes a first positioning pin assembly 30A and a second positioning pin assembly 30B disposed at intervals along a first direction X on the mounting surface 101, the first positioning pin assembly 30A and the second positioning pin assembly 30B being respectively used to insert into positioning holes in the body-in-white parts, the first direction X being perpendicular to the gravity direction Z; wherein, at least one of the first positioning pin assembly 30A and the second positioning pin assembly 30B is adjustablely disposed on the mounting surface 101 along the first direction X.

[0041] The body 10 is a component used to drive the movement of other structural parts.

[0042] In some embodiments, the bottom of the vehicle body 10 is provided with a plurality of casters 11, and at least one of the casters 11 is provided with a braking mechanism. In some embodiments, a handle 12 is provided on one side of the vehicle body 10.

[0043] Mounting surface 101 is the surface of the vehicle body 10 that is away from the ground in the direction of gravity Z. In embodiments where the vehicle body 10 is a frame structure, mounting surface 101 is the side of the vehicle body 10 that is away from the ground.

[0044] In some embodiments, a calibration hole 102 may be provided on the mounting surface 101. The calibration hole 102 is used as a scanning reference for the three-dimensional scanning device so that the operator can calibrate the limiting structure and support structure on the mounting surface 101.

[0045] The support block 20 is a structural component used to support the body-in-white parts. In some embodiments, the support block 20 and the positioning pin assembly 30 are spaced apart along the second direction Y to uniformly support the body-in-white parts along the second direction Y, thereby improving the stability of the unloading trolley when carrying the body-in-white parts.

[0046] One of the first locating pin assembly 30A and the second locating pin assembly 30B is a main locating pin, which is used to be inserted into the main locating hole of the body-in-white part, and the other is a secondary locating pin, which is used to be inserted into the secondary locating hole of the body-in-white part.

[0047] The first direction X and the second direction Y are two mutually perpendicular horizontal directions.

[0048] Understandably, the distance between the main and auxiliary positioning holes differs on different body-in-white parts.

[0049] In this technical solution, by setting one of the first positioning pin assembly 30A and the second positioning pin assembly 30B to be adjustable along the first direction X on the mounting surface 101, the first positioning pin assembly 30A and the second positioning pin assembly 30B can be adapted to different body-in-whites with different positioning hole distances. This allows the unloading trolley to fix and transport different models of body-in-whites. This improves the applicability of the unloading trolley and reduces the risk of wasted workshop space caused by unused unloading trolleys.

[0050] According to some embodiments of this application, refer to Figure 1 and Figure 2 The unloading trolley also includes a mounting component 40 and a guide rail 41. The mounting component 40 is disposed on the mounting surface 101; the guide rail 41 is disposed on the side of the mounting component 40 away from the mounting surface 101 and extends along the first direction X, and the first mounting seat 31A of the first positioning pin assembly 30A is slidably disposed on the guide rail 41.

[0051] In this technical solution, by slidably setting the first mounting base 31A of the first positioning pin assembly 30A on the guide rail 41, on the one hand, the first mounting base 31A of the first positioning pin assembly 30A can move more stably along the first direction X, improving the reliability of the unloading trolley positioning; on the other hand, it reduces the risk that the first positioning pin assembly 30A and the second positioning pin assembly 30B will fail to limit the positioning of the body-in-white parts due to the first positioning pin assembly 30A deviating in the second direction Y when moving along the first direction X, which would prevent the first positioning pin assembly 30A and the second positioning pin assembly 30B from being inserted into the corresponding positioning holes of the body-in-white parts.

[0052] According to some embodiments of this application, refer to Figure 1 and Figure 2 The unloading trolley also includes a locking pin 42. The locking pin 42 is adjustable along the gravity direction Z and is set on the first mounting base 31A. The mounting part 40 is provided with a first limiting hole 401 corresponding to the locking pin 42 on the side opposite to the mounting surface 101. There are multiple first limiting holes 401 spaced apart along the first direction X. One end of the locking pin 42 is inserted into the first limiting hole 401 to fix the first mounting base 31A relative to the guide rail 41.

[0053] For example, the locking pin 42 can be a ball-head locking pin, which is prior art and will not be described in detail here.

[0054] In some embodiments, the mounting component 40 includes a mounting plate 40A and a limiting strip 40B. The mounting plate 40A is disposed on the mounting surface 101, and the thickness direction of the mounting plate 40A is perpendicular to the gravity direction Z. A guide rail 41 is disposed on the side of the mounting plate 40A away from the mounting surface 101. The limiting strip 40B is disposed on the side of the mounting plate 40A away from the mounting surface 101 and extends along the first direction X. A first limiting hole 401 is disposed on the limiting strip 40B. It can be understood that the limiting strip 40B is detachably connected to the mounting plate 40A so that the mounting component 40 can be adapted to body-in-white parts of different vehicle models by replacing the limiting strip 40B.

[0055] In this technical solution, by inserting one end of the locking pin 42 into different first limiting holes 401, the first mounting base 31A is fixed relative to the second positioning pin assembly 30B at different positions, thereby enabling the first positioning pin assembly 30A and the second positioning pin assembly 30B to limit different models of body-in-white parts. The structure is simple and easy to implement.

[0056] According to some embodiments of this application, please refer to Figure 2 and Figure 3 The positioning pin assembly 30 includes a mounting base, a connector, a positioning pin, and a first washer 34A.

[0058] According to some embodiments of this application, the positioning pin assembly 30 further includes a first abutment pin 35A, a second washer 36A, a second abutment pin 37A, and a third washer 38A. The first abutment pin 35A is disposed on the mounting base and located on one side of the connector in the first direction X; the second washer 36A is sandwiched between the connector and the first abutment pin 35A along the first direction X; the second abutment pin 37A is disposed on the mounting base and located on one side of the connector in the second direction Y, wherein the first direction X, the second direction Y, and the gravity direction Z are perpendicular to each other; the third washer 38A is sandwiched between the connector and the second abutment pin 37A along the second direction Y.

[0059] In some embodiments, please refer to Figure 2The first positioning pin assembly 30A includes a first mounting base 31A, a first connector 32A, a first positioning pin 33A, a first gasket 34A, a first abutment pin 35A, a second gasket 36A, a second abutment pin 37A, and a third gasket 38A. The first mounting base 31A is slidably disposed on the guide rail 41. The first connecting member 32A is detachably mounted on the side of the first mounting base 31A away from the mounting surface 101 along the gravity direction Z. The first positioning pin 33A is disposed on the first connecting member 32A. The first gasket 34A is clamped between the first connecting member 32A and the first mounting base 31A along the gravity direction Z. The first abutment pin 35A is disposed on the first mounting base 31A and located on the side of the first connecting member 32A in the first direction X. The second gasket 36A is clamped between the first connecting member 32A and the first abutment pin 35A along the first direction X. The second abutment pin 37A is disposed on the first mounting base 31A and located on the side of the first connecting member 32A in the second direction Y. The third gasket 38A is clamped between the first connecting member 32A and the second abutment pin 37A along the second direction Y.

[0060] In some embodiments, please refer to Figure 3 The second positioning pin assembly 30B includes a second mounting base 31B, a second connector 32B, a second positioning pin 33B, a first gasket 34A, a first abutment pin 35A, a second gasket 36A, a second abutment pin 37A, and a third gasket 38A. The second mounting base 31B is slidably disposed on the guide rail 41. The second connecting member 32B is detachably mounted on the side of the second mounting base 31B away from the mounting surface 101 along the gravity direction Z. The second positioning pin 33B is disposed on the second connecting member 32B. The first gasket 34A is clamped between the second connecting member 32B and the second mounting base 31B along the gravity direction Z. The first abutment pin 35A is disposed on the second mounting base 31B and located on the side of the second connecting member 32B in the first direction X. The second gasket 36A is clamped between the second connecting member 32B and the first abutment pin 35A along the first direction X. The second abutment pin 37A is disposed on the second mounting base 31B and located on the side of the second connecting member 32B in the second direction Y. The third gasket 38A is clamped between the second connecting member 32B and the second abutment pin 37A along the second direction Y.

[0061] In this technical solution, by clamping the second shim 36A between the connector and the first abutment 35A along the first direction X, and by clamping the third shim 38A between the connector and the second abutment 37A along the second direction Y, the position of the positioning pin in the second direction Y and the first direction X is adjusted so that the positioning pin can be better inserted into the positioning hole of the body-in-white part, thereby increasing the stability of the unloading trolley in fixing the body-in-white part.

[0062] According to some embodiments of this application, please refer to Figure 1 Please refer to Figures 4-6The unloading trolley also includes a clamping mechanism 50, which is located on the mounting surface 101, and the support block 20 is clamped to the clamping mechanism 50.

[0063] In this technical solution, by engaging the support block 20 with the engagement mechanism 50, the support block 20 is detachably connected to the body 10. This facilitates the replacement of different support blocks 20 for different body-in-white parts, enabling the unloading trolley to fix and transport different models of body-in-white. This further expands the applicability of the unloading trolley and reduces the risk of wasted workshop space caused by unused unloading trolleys.

[0064] According to some embodiments of this application, please refer to Figure 1 Please refer to Figures 4-6 The latching mechanism 50 includes a mounting tube 51 and a latch 52. The mounting tube 51 is disposed on the mounting surface 101 and has a first end 51A and a second end 51B, with the second end 51B located above the first end 51A. The latch 52 is rotatably disposed on the first end 51A along a rotation axis perpendicular to the direction of gravity Z. The support block 20 has an insertion end 21 for inserting into the second end 51B, and a slot 211 adapted to the latch 52 is provided on the periphery of the insertion end 21.

[0065] For example, the rotation direction of the latch 52 can be parallel to the first direction X. The slot 211 is provided on the side of the insertion end 21 facing the latch 52 in the second direction Y.

[0066] In this technical solution, after the insertion end 21 is inserted into the second end 51B, the slot 211 on the periphery of the insertion end 21 engages with the buckle 52 to prevent the insertion end 21 from detaching from the mounting tube 51. At the same time, the second end 51B is located above the first end 51A, so that when the support block 20 carries the body-in-white parts, the pressure of the body-in-white parts can drive the insertion end 21 to move towards the first end 51A, further reducing the risk of the insertion end 21 detaching from the mounting tube 51 and improving the reliability of the unloading trolley during use.

[0067] According to some embodiments of this application, please refer to Figures 4-6 The snap-fit ​​mechanism 50 also includes a first elastic element 53, which is disposed inside the mounting tube 51 and is used to provide elastic force to the snap-fit ​​52 so that the snap-fit ​​52 snaps into the slot 211.

[0068] For example, the first elastic element 53 can be a compression spring.

[0069] In some embodiments, one end of the first elastic member 53 in the second direction Y is connected to the inner wall of the mounting tube 51 in the second direction Y away from the buckle 52, and the other end of the first elastic member 53 in the second direction Y is connected to the buckle 52. When the buckle 52 rotates about its rotation axis in the direction of disengaging from the slot 211, the first elastic member 53 is compressed. The first elastic member 53 elastically resets to drive the buckle 52 to engage in the slot 211.

[0070] In some embodiments, the insertion end 21 is provided with a guide surface, which slides relative to the buckle 52 in the direction of gravity Z to guide the buckle 52 to rotate about its rotation axis in the direction of disengaging from the slot 211.

[0071] In this technical solution, the first elastic element 53 drives the buckle 52 to engage with the slot 211. The structure is simple and easy to implement.

[0072] According to some embodiments of this application, please refer to Figures 4-6 The side wall of the mounting tube 51 is provided with a second limiting hole 511 that communicates with the interior of the mounting tube 51, and a third limiting hole 212 is provided on the periphery of the insertion end 21. The buckle 52 engages with the slot 211 so that the second limiting hole 511 is aligned with the third limiting hole 212. The engaging mechanism 50 also includes a plug pin 54, which passes through the second limiting hole 511 and the third limiting hole 212 in sequence to fix the insertion end 21 relative to the mounting tube 51.

[0073] In this technical solution, by passing the insertion pin 54 through the second limiting hole 511 and the third limiting hole 212 in sequence to fix the insertion end 21 relative to the mounting tube 51, the risk of the insertion end 21 disengaging from the mounting tube 51 is further reduced, and the reliability of the unloading trolley during use is further improved.

[0074] According to some embodiments of this application, please refer to Figure 1 Please refer to Figure 7 and Figure 8 The unloading trolley also includes a locking structure 60, which is telescopically mounted on the side of the vehicle body 10 facing the ground along the direction of gravity Z. One end of the locking structure 60 extends relative to the vehicle body 10 and is inserted into the fourth limiting hole on the ground to fix the vehicle body 10 relative to the ground.

[0075] In some embodiments, refer to Figure 7The locking structure 60 includes a mounting cylinder 62, a telescopic member 61, and a second elastic member 63. The mounting cylinder 62 is mounted on the vehicle body 10, with its axis parallel to the direction of gravity Z. The telescopic member 61 extends along the direction of gravity Z, and its middle portion is movably inserted into the mounting cylinder 62. The second elastic member 63 is connected to both the mounting cylinder 62 and the telescopic member 61, and provides an elastic force to the telescopic member 61 to guide the end of the telescopic member 61 near the ground to move away from the mounting cylinder 62. A pedal 13 is also provided on the vehicle body 10, with its middle portion rotatably mounted on the vehicle body 10. One end of the pedal 13 is hinged to one end of the telescopic member 61. An external force in the direction of gravity Z is applied to the other end of the pedal 13 to cause the pedal 13 to drive the telescopic member 61 to move away from the ground.

[0076] Understandably, the hinge hole at the hinge point between the pedal 13 and the telescopic member 61 is a strip-shaped hole, so that when the pedal 13 rotates, it can still drive the telescopic member 61 to move along the direction of gravity Z.

[0077] In some implementations, refer to Figure 7 An infrared sensor 100 is installed on the ground to detect whether the telescopic component 61 is inserted into the fourth limiting hole.

[0078] In some embodiments, refer to Figure 7 The bottom of the vehicle body 10 is also provided with a guide wheel 14. The guide wheel 14 is used to abut against the sliding rail structure on the ground to guide the vehicle body 10 to move along a preset line. For example, the rotation axis of the guide wheel 14 can be parallel to the direction of gravity Z, and / or the rotation axis of the guide wheel 14 can be parallel to the first direction X.

[0079] In this technical solution, by extending one end of the locking structure 60 relative to the body 10 and inserting it into the fourth limiting hole on the ground, the body 10 is fixed relative to the ground, which makes it easier for the unloading trolley to be fixed at the unloading station, thereby reducing the risk of the body-in-white parts falling and being damaged due to the movement of the trolley during the unloading process.
