Description

Technical Field

[0001] The invention relates to the field of automobile parts production, specifically to the field of automobile roof lining production, and particularly to a transportation device for automobile roof lining production. Background Art

[0002] The automobile roof lining is one of the components of the automobile structure, which is generally in an arc shape. During the production process, the produced automobile roof lining needs to be transferred to a warehouse for storage. When the automobile is assembled, the automobile roof lining needs to be transferred from the warehouse to the assembly line. Therefore, the automobile roof lining needs to be transported. In the prior art, the automobile roof lining is generally transported by a transfer vehicle. Since the automobile roof lining is in an arc shape, the automobile roof lining cannot be stacked too much to prevent the automobile roof lining below from being pressed and deformed. Since the automobile roof lining is placed vertically, it is easy to shake and fall over during transportation. Therefore, it is necessary to improve the existing transfer vehicle technology to solve this problem.

[0003] Based on the above, the present invention proposes a transport device for automobile roof lining production. Summary of the invention

[0004] In order to solve the problems mentioned in the above background, the present invention provides a transport device for producing automobile headliners.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0006] A transport device for automobile roof lining production, comprising a transport vehicle, a vehicle frame is provided on the upper surface of the transport vehicle, a storage mechanism is installed on the vehicle frame, the storage mechanism comprises a first storage component, a second storage component and a motor, the first storage component and the second storage component both comprise a horizontally arranged supporting seat, the supporting seat of the first storage component is structurally connected to the vehicle frame via a first mounting assembly, and the supporting seat of the second storage component is structurally connected to the vehicle frame via a second mounting assembly;

[0007] The storage mechanism is configured to switch between state one and state two. When the storage mechanism is in state one, the supporting seat of the first storage component is located directly above the supporting seat of the second storage component. When the storage mechanism is in state two, the supporting seat of the first storage component and the supporting seat of the second storage component are arranged side by side and have the same height.

[0008] Furthermore, the first mounting assembly includes a fixing seat connected to the frame and a vertically arranged drive shaft;

[0009] A first gear is arranged on the fixed seat, a friction member is arranged inside the first gear, and the friction member is dynamically connected with the driving shaft. When the friction member rotates with the driving shaft, the friction member rotates with the first gear through the friction force between the friction member and the first gear.

[0010] Furthermore, a first movable horizontal frame is slidably arranged on the fixed seat, the sliding direction of the first movable horizontal frame is parallel to the width direction of the transport vehicle, a first rack is arranged on the first movable horizontal frame, the extension direction of the first rack is parallel to the width direction of the transport vehicle, and the first gear is meshed with the first rack;

[0011] The first movable horizontal frame is connected to the supporting seat of the first storage component.

[0012] Furthermore, the friction part includes a fixed ring arranged on the upper end face of the first gear, the inner wall of the first gear is in the shape of a truncated cone with a diameter increasing from bottom to top, a conical sleeve is coaxially provided inside the first gear, a first spring is arranged between the conical sleeve and the fixed ring, under the elastic force of the first spring, the outer cylindrical surface of the conical sleeve fits with the inner wall of the first gear, and the conical sleeve is arranged on the drive shaft through a spline sleeve.

[0013] Furthermore, the second mounting assembly includes a vertically arranged threaded shaft and a movable seat slidably arranged on the frame, and the sliding direction of the movable seat is vertically arranged;

[0014] A second gear is provided on the movable seat, and the connection relationship between the second gear and the threaded shaft is consistent with the connection relationship between the first gear and the driving shaft;

[0015] A second movable horizontal frame is slidably arranged on the movable seat, the sliding direction of the second movable horizontal frame is parallel to the width direction of the transport vehicle, a second rack is arranged on the second movable horizontal frame, the extension direction of the second rack is parallel to the width direction of the transport vehicle, and the second rack is meshed with the second gear;

[0016] The second movable horizontal frame is connected to the supporting seat of the second storage component.

[0017] Furthermore, a threaded half-seat is slidably arranged on the movable seat, and the sliding direction of the threaded half-seat is parallel to the width direction of the transport vehicle. Two threaded half-seats are arranged along their own sliding direction, and a second spring is arranged between the two threaded half-seats. The two facing sides of the two threaded half-seats are each provided with an arc surface, and the arc surface is provided with an internal thread. Initially, the elastic force of the second spring causes a gap to exist between the two threaded half-seats, and the arc surface does not contact the threaded shaft. When the elastic force of the second spring is overcome and the two threaded half-seats are in contact with each other, the two arc surfaces form a complete threaded hole and the threaded hole and the threaded shaft form a threaded connection.

[0018] Furthermore, a trigger seat is slidably arranged on the movable seat, and the sliding direction of the trigger seat is parallel to the length direction of the transport vehicle. Two inclined planes 1 are arranged on the side of the trigger seat facing the threaded half seat, and the distance between the two inclined planes 1 increases along the sliding direction of the trigger seat and from the trigger seat to the direction of the threaded half seat. Inclined plane 2 is arranged on the side of the threaded half seat facing the trigger seat, and the inclined planes 2 on the two threaded half seats are respectively parallel to the two inclined planes 1, and the two inclined planes 1 are respectively fitted with the two inclined planes 2.

[0019] Furthermore, a trigger rod is provided on the second movable horizontal frame, a slope three is provided on the trigger rod, and a slope four is provided on the trigger seat. The slope three is parallel to the slope four. When the two supporting seats move away from each other and the movement distance of the supporting seat of the second storage member reaches the maximum, the slope three contacts the slope four and through the cooperation of the two, the trigger seat is driven to move close to the threaded half seat, so that the two threaded half seats form a threaded connection with the threaded shaft.

[0020] Furthermore, the motor and the threaded shaft form a power connection, and the threaded shaft and the drive shaft are connected to each other through a power transmission member, and the transmission ratio of the power transmission member is one.

[0021] Furthermore, an external step is provided at the bottom of the threaded shaft, and a third spring located above the external step is sleeved on the outside of the threaded shaft.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When the present solution is used, the automobile roof lining is stacked on the supporting seat, so it is difficult to shake during transportation. Furthermore, two supporting seats are provided for stacking the automobile roof lining, so more automobile roof linings can be transported at one time. Furthermore, during transportation, the two supporting seats are arranged in parallel up and down, so the transport device occupies a small area, has a stable center of gravity, and the transport vehicle can move smoothly and stably in a narrow walking area.

[0024] In the process of switching the states of the two supporting seats of the storage mechanism of the transport vehicle, it is driven by a single power source, the motor. The advantage is that the motor can drive the following actions: the two supporting seats move away from each other - the supporting seat of the second storage component moves up - the supporting seat of the second storage component moves down, and at the same time the two supporting seats approach each other. Therefore, it can play the following roles: on the one hand, when the states of the two supporting seats are switched, they move in different directions and at the same speed, so it will not cause a large shift in the center of gravity of the transport vehicle, and the stability is better. On the other hand, the connection of the above actions is smooth without any delay, so the efficiency is high. On the other hand, the cooperation of the motor, the first mounting assembly and the second mounting assembly, in the process of the two supporting seats switching from left and right side by side arrangement to upper and lower side by side arrangement, because the second storage component falls under the action of gravity and the speed is faster, the time spent in the whole process is equal to the reset time of the two supporting seats approaching each other, so the switching efficiency is significantly improved, thereby greatly improving the transportation efficiency.

DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] In the attached drawings of this scheme, a refers to the automobile roof lining, which is generally in an arc shape. This scheme simply illustrates the automobile roof lining in a plane shape.

[0038] Reference Figure 1-Figure 9 A transport device for automobile roof lining production includes a transport vehicle 100. The upper surface of the transport vehicle 100 is provided with a frame, and a storage mechanism 200 is installed on the frame.

[0039] The storage mechanism 200 includes a first storage component, a second storage component and a motor 201. The first storage component and the second storage component are used to store the automobile roof lining. Figure 2 As shown, the first storage member and the second storage member are arranged side by side, so that the automobile roof lining can be stacked on the first storage member or the second storage member, or the automobile roof lining can be taken off from the first storage member or the second storage member. Figure 2 As shown, the first storage component and the second storage component are arranged side by side up and down, which is significant in that the footprint of the transport device is reduced, thereby facilitating walking in a factory. There are many production lines in a factory, and the area for walking is relatively narrow. Therefore, it is necessary to reduce the footprint of the transport device. In addition, this method can also prevent the center of gravity of the transport device from shifting, making transportation more stable and smooth, and it is unlikely to shake or tip over. It should be noted that when the left and right side-by-side arrangements for storage or retrieval occur, the transport vehicle 100 is stationary, and since the first storage component and the second storage component move simultaneously and have the same direction and speed, the center of gravity of the transport vehicle 100 will not shift significantly, that is, the transport vehicle 100 stops steadily.

[0040] The first storage component and the second storage component both include a horizontally arranged supporting seat 203 .

[0041] The supporting seat 203 of the first storage member is connected to the vehicle frame through the first mounting assembly 204 .

[0042] The supporting seat 203 of the second storage member is connected to the vehicle frame through the second mounting assembly 205 .

[0043] First installation component 204:

[0044] Reference Figure 4-Figure 6 The first mounting assembly 204 includes a fixing seat 207 connected to the vehicle frame and a vertically arranged driving shaft 210.

[0045] A first gear 209 is arranged on the fixed seat 207, and a fixing ring 2092 is arranged on the upper end face of the first gear 209. The inner wall of the first gear 209 is in the shape of a truncated cone with a diameter increasing from bottom to top. A conical sleeve 2091 is coaxially sleeved inside the first gear 209, and a first spring 2093 is arranged between the conical sleeve 2091 and the fixing ring 2092. Under the elastic force of the first spring 2093, the outer cylindrical surface of the conical sleeve 2091 fits with the inner wall of the first gear 209. The conical sleeve 2091 is arranged on the driving shaft 210 through a spline sleeve. When the driving shaft 210 rotates, it rotates with the conical sleeve 2091. Through the action of friction, the conical sleeve 2091 rotates with the first gear 209.

[0046] A first movable horizontal frame 206 is slidably arranged on the fixed seat 207, and the sliding direction of the first movable horizontal frame 206 is parallel to the vehicle width direction of the transport vehicle 100. A first rack 208 is arranged on the first movable horizontal frame 206, and the extension direction of the first rack 208 is parallel to the vehicle width direction of the transport vehicle 100. The first gear 209 is meshed with the first rack 208; when the first gear 209 rotates, it can drive the first rack 208 to move, and the first rack 208 moves with the first movable horizontal frame 206. In addition, when the first rack 208 moves to the maximum distance, the first gear 209 cannot continue to rotate. At this time, the drive shaft 210 can still continue to rotate, and the conical sleeve 2091 idles.

[0047] Second installation component 205:

[0048] Reference Figure 4 and Figure 7-Figure 9 The second mounting assembly 205 includes a vertically arranged threaded shaft 213 and a movable seat 212 slidably arranged on the frame, and the sliding direction of the movable seat 212 is vertically arranged.

[0049] A second gear 215 is provided on the movable seat 212. The connection relationship between the second gear 215 and the threaded shaft 213 is consistent with the connection relationship between the first gear 209 and the driving shaft 210, that is, the second gear 215 and the threaded shaft 213 are also dynamically connected through the tapered sleeve 2091, the first spring 2093 and the fixing ring 2092. It should be noted that the tapered sleeve 2091 in the second gear 215 and the threaded shaft 213 constitute a dynamic connection, but do not constitute a threaded connection. There is a gap between the external thread on the threaded shaft 213 and the tapered sleeve 2091 in the second gear 215. Therefore, when the threaded shaft 213 rotates, it can rotate with the second gear 215, and the second gear 215 can and only rotate.

[0050] A second movable horizontal frame 211 is slidably arranged on the movable seat 212, and the sliding direction of the second movable horizontal frame 211 is parallel to the vehicle width direction of the transport vehicle 100. A second rack 214 is arranged on the second movable horizontal frame 211, and the extension direction of the second rack 214 is parallel to the vehicle width direction of the transport vehicle 100. The second rack 214 is meshed with the second gear 215; when the second gear 215 rotates, it can drive the second rack 214 to move, and the second rack 214 moves with the second movable horizontal frame 211. Similarly, when the second rack 214 moves to the maximum distance, the second gear 215 cannot continue to rotate. At this time, the threaded shaft 213 can still continue to rotate, and the tapered sleeve 2091 idles.

[0051] A threaded half seat 217 is slidably arranged on the movable seat 212, and the sliding direction of the threaded half seat 217 is parallel to the vehicle width direction of the transport vehicle 100. Two threaded half seats 217 are arranged along their own sliding direction, and a second spring 218 is arranged between the two threaded half seats 217. The two threaded half seats 217 are each provided with an arc surface on the opposite side, and the central angle of the arc surface is 180 degrees. The arc surface is provided with an internal thread. Initially, the elastic force of the second spring 218 causes a gap to exist between the two threaded half seats 217, so that the arc surface does not contact the threaded shaft 213. When the elastic force of the second spring 218 is overcome and the two threaded half seats 217 are in contact with each other, the two arc surfaces form a complete threaded hole and the threaded hole and the threaded shaft 213 form a threaded connection.

[0052] A trigger seat 219 is slidably arranged on the movable seat 212, and the sliding direction of the trigger seat 219 is parallel to the vehicle length direction of the transport vehicle 100. Two inclined planes 1 are arranged on the side of the trigger seat 219 facing the threaded half seat 217, and the distance between the two inclined planes 1 increases along the sliding direction of the trigger seat 219 and from the trigger seat 219 to the direction of the threaded half seat 217. A inclined plane 2 is arranged on the side of the threaded half seat 217 facing the trigger seat 219, and the inclined planes 2 on the two threaded half seats 217 are respectively parallel to the two inclined planes 1.

[0053] A trigger rod 216 is provided on the second movable horizontal frame 211, and a slope three is provided on the trigger rod 216. A slope four is provided on the trigger seat 219, and the slope three is parallel to the slope four. When the two supporting seats 203 move away from each other and the movement distance of the supporting seat 203 of the second storage member reaches the maximum, the slope three contacts the slope four and through the cooperation of the two, the trigger seat 219 is driven to move close to the threaded half seat 217, so that the two threaded half seats 217 form a threaded connection with the threaded shaft 213.

[0054] The motor 201 and the threaded shaft 213 form a power connection, and the threaded shaft 213 and the driving shaft 210 are connected to each other through the power transmission member 202. The transmission ratio of the power transmission member 202 is 1, and the sizes of the first gear 209 and the second gear 215 are consistent.

[0055] Preferably, an external step is provided at the bottom of the threaded shaft 213, and a third spring 220 located above the external step is sleeved on the outside of the threaded shaft 213, and the third spring 220 plays a buffering role.

[0056] The two supporting seats 203 are connected to the first movable horizontal frame 206 and the second movable horizontal frame 211 respectively.

[0057] Working principle of the present invention:

[0058] Initially, if Figure 1 As shown, the two supporting seats 203 are arranged in parallel up and down;

[0059] The motor 201 is started, driving the threaded shaft 213 and the drive shaft 210 to rotate simultaneously at the same speed:

[0060] The driving shaft 210 rotates with the first gear 209, and the first gear 209 cooperates with the first rack 208 to drive the first movable horizontal frame 206 to move. The first movable horizontal frame 206 moves with the supporting seat 203 connected thereto. After the first movable horizontal frame 206 reaches the maximum distance, the driving shaft 210 can continue to rotate, and the tapered sleeve 2091 in the first gear 209 idles.

[0061] The threaded shaft 213 rotates with the second gear 215, thereby driving the second movable horizontal frame 211 to move, and the second movable horizontal frame 211 moves with the supporting seat 203 connected thereto. It should be noted that the movement direction of the second movable horizontal frame 211 is opposite to the movement direction of the first movable horizontal frame 206, so the two supporting seats 203 move away from each other. Since the movement speeds are the same and the directions are opposite, the center of gravity of the transport vehicle 100 will not be greatly offset during this process, and the transport vehicle 100 will not shake or deviate, and will stay in place.

[0062] After the first movable horizontal frame 206 and the second movable horizontal frame 211 have reached the maximum movement distance, the two supporting seats 203 are unfolded. At this time, the trigger rod 216 cooperates with the trigger seat 219 to make the threaded half seat 217 and the threaded shaft 213 form a threaded connection. The threaded shaft 213 continues to rotate, and the threaded half seat 217 moves upward, thereby moving the second storage member upward, and the corresponding supporting seat 203 moves upward, so that the two supporting seats 203 are arranged side by side and at the same height.

[0063] The automobile headliner is placed on two supporting seats 203 manually or by existing robot arm technology;

[0064] After stacking, the motor 201 runs in the reverse direction. During this process, the two supporting seats 203 move toward each other. At the same time, the threaded connection between the threaded half seat 217 and the threaded shaft 213 in the second storage member is loosened, and the second storage member falls rapidly under the action of gravity until it is reset.

[0065] After the transport vehicle 100 moves to the preset position, the above process is repeated so that the two supporting seats 203 are arranged side by side and at the same height. The car roof lining is removed manually or by existing robotic arm technology, and then the storage mechanism 200 is reset.

[0066] From the above description, we can know that:

[0067] When the present solution is used, the automobile roof lining is stacked on the supporting seat, so it is difficult to shake during transportation. Furthermore, two supporting seats are provided for stacking the automobile roof lining, so more automobile roof linings can be transported at one time. Furthermore, during transportation, the two supporting seats are arranged in parallel up and down, so the transport device occupies a small area, has a stable center of gravity, and the transport vehicle can move smoothly and stably in a narrow walking area.

[0068] In the process of switching the states of the two supporting seats of the storage mechanism of the transport vehicle, it is driven by a single power source, the motor. The advantage is that the motor can drive the following actions: the two supporting seats move away from each other - the supporting seat of the second storage component moves up - the supporting seat of the second storage component moves down, and at the same time the two supporting seats approach each other. Therefore, it can play the following roles: on the one hand, when the states of the two supporting seats are switched, they move in different directions and at the same speed, so it will not cause a large shift in the center of gravity of the transport vehicle, and the stability is better. On the other hand, the connection of the above actions is smooth without any delay, so the efficiency is high. On the other hand, the cooperation of the motor, the first mounting assembly and the second mounting assembly, in the process of the two supporting seats switching from left and right side by side arrangement to upper and lower side by side arrangement, because the second storage component falls under the action of gravity and the speed is faster, the time spent in the whole process is equal to the reset time of the two supporting seats approaching each other, so the switching efficiency is significantly improved, thereby greatly improving the transportation efficiency.

[0069] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
