Description

Transport system and component surface treatment device using the same Technical Field

[0001] The present invention relates to the technical field of vehicle component surface treatment, and more particularly to a transportation system and a component surface treatment device using the system. Background Art

[0002] In the automotive industry, the vehicle body, chassis and other structural components undergo a variety of treatments, such as rinsing, degreasing, activator treatment, phosphating treatment, passivation treatment, electrophoresis treatment and ultrafiltration treatment. Most of these treatments, such as degreasing, phosphating and electrophoresis treatment, require the vehicle structural components to be completely immersed in the treatment unit tank.

[0003] To this end, the vehicle production plant is equipped with a production line, including several processing unit tanks arranged continuously between them. There is a specific processing liquid in the processing unit tank, and the vehicle structural components need to be immersed in the processing liquid for specific treatment. Generally speaking, the processing tank of the motor vehicle production line is composed of 13 processing unit tanks; in order to process each vehicle structural component, it is stipulated that each vehicle structural component should be fixed on a transportation mechanism (i.e., a transportation trolley), move along a specific moving route and immerse itself in the processing unit tank.

[0004] According to the first type of processing line for vehicle structural components, this type of line provides a chain drive system, and when necessary, when each transport mechanism supports the component to be processed, they are hooked to the chain drive system each time. Therefore, this type of processing line has a very obvious advantage, that is, only the transport mechanism loaded with the component to be processed is transported, thereby avoiding the immersion of empty transport mechanisms (i.e., transport mechanisms not loaded with the component to be processed) into the processing tank.

[0005] In addition to providing a conveyor chain for the transport mechanisms and processing tanks, a station must be provided upstream of the conveyor chain to load / hook up the transport mechanisms when transporting the parts to be processed, and a station must be provided downstream to unload the transport mechanisms on the conveyor chain so that each transport mechanism moves forward and the corresponding processed parts move to the subsequent line.

[0006] Furthermore, it should be noted that the above-described power-and-free conveyor chain provides hooks integrated with the chain for engaging a specific transport mechanism at an upstream station and releasing the same transport mechanism at a downstream station.

[0007] Although this type of processing line is very common, it also has disadvantages. Considering the size of each processing unit slot, a large line is required. In fact, in order to achieve the immersion of the transport mechanism and the corresponding parts to be processed in the processing unit slot, the entire drive and support line of the conveyor chain and the transport mechanism must be lowered. This can only be achieved in front of the processing unit slot, which provides a descending slope at the entrance and an appropriate reverse exit slope at the exit. In this regard, considering the inclination angle used is 28° to 45°, the corresponding lowering height is 1m or even more. It should be noted that if the slopes at the entrance and exit of the processing unit slot are very long, the length of the processing unit slot will be greatly increased, and the volume of the processing unit slot will also be greatly increased.

[0008] Therefore, it is necessary to provide a transportation system and a component surface treatment device using the system to at least partially solve the problems existing in the prior art.

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0060] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0061] As shown in FIG1 , the present invention provides a transport system comprising: a conveyor chain 1 disposed on one side of a processing tank, wherein the portion of the conveyor chain 1 corresponding to the processing tank forms a processing path P, and the portions of the conveyor chain 1 corresponding to both ends of the processing tank form an upstream station 2 and a downstream station 3, respectively;

[0062] A plurality of transport mechanisms 4 are provided on the conveyor chain 1, each transport mechanism 4 being used for hooking, supporting and transporting a component V to be processed;

[0063] The control module is used to control the upstream station 2 and the downstream station 3 to input and output the transport mechanism 4 from the processing path P respectively, control the transport mechanism 4 to selectively combine with the conveyor chain 1 at the upstream station 2 and switch the working state of the transport mechanism 4. When the component V to be processed is loaded on the transport mechanism 4, the transport mechanism 4 is controlled to move along the processing path P, and at the same time, the component V to be processed can be continuously flipped to be immersed in the processing liquid in the processing tank.

[0064] As shown in Figures 2, 7 and 10, when the transport mechanism 4 has not entered the upstream station 2, the transport mechanism 4 is in a waiting state. When it enters the upstream station 2, the transport mechanism 4 is controlled by the control module to switch the state and selectively combines with the conveyor chain 1. When the transport mechanism 4 switches to the conveying state, it contacts the reverse support and slide rails 7 provided at the two opposite longitudinal sides of the processing tank. Then, the parts V to be processed are loaded onto the transport mechanism 4, and the transport mechanism 4 can be controlled to move along the processing path P. During the movement, the transport mechanism 4 can drive the parts V to be processed to be continuously flipped so that they are immersed in the processing liquid of the processing tank;

[0065] Through the above design, the control module can control the switching state of the transport mechanism 4 and the selective combination of the transport mechanism 4 with the conveyor chain 1 at the upstream station 2 according to the position of the transport mechanism 4 on the conveyor chain 1, so as to ensure the orderly progress of the entire processing process, prevent the transport mechanism 4 from being blocked during the transportation process or prevent the transport mechanism 4 without the parts V to be processed from being immersed in the processing liquid, thereby ensuring the processing efficiency and realizing automatic control.

[0066] Moreover, during the movement of the transport mechanism 4 along the processing path P, the component V to be processed can be driven to continuously flip, so that the component V to be processed can be completely immersed in the processing liquid, thereby achieving the purpose of processing and solving the problem of the processing tank being too large.

[0067] In one embodiment, the control module includes:

[0068] A first detection unit is used to detect whether the transport mechanism 4 at the last position moving along the processing path P has moved to a safe position;

[0069] The mobile control unit is used to control the transport mechanism 4 at the first position at the upstream station 2 to combine with the conveyor chain 1 and start switching the working state of the transport mechanism 4 when the first detection unit detects that the transport mechanism 4 at the last position moving along the processing path P moves to a safe position.

[0070] In this embodiment, the safe position is the position of the transport mechanism 4 at this location, which will not affect the flipping of the component V to be processed on the transport mechanism 4 that is about to enter the processing path P, and prevents the collision between the two components V to be processed in front and behind; the mobile control unit controls the transport mechanism 4 at the first position of the upstream station 2 through the detection result of the first detection unit to move, so that the transport mechanism 4 at the first position is combined with the conveyor chain 1 and starts to switch the working state of the transport mechanism 4, indicating that this transport mechanism 4 can start to prepare to load the component V to be processed, thereby ensuring the continuity of the processing process.

[0071] In one embodiment, the working state switching of the transport mechanism 4 includes: switching from a waiting state to a standby state, wherein the transport mechanism 4 moves to an initial engagement position in the standby state, and then switching from the standby state to a conveying state, wherein the transport mechanism 4 moves along the processing path P in the conveying state;

[0072] The initial engagement position is the initial engagement position of the transport mechanism 4 and the guide element 5 provided on the processing tank.

[0073] Furthermore, the transport mechanism 4 includes: a first transport part 41 for selectively combining with the conveyor chain 1, and a second transport part 42 for hooking, supporting and transporting the component V to be processed; the second transport part 42 is connected to the first transport part 41 through a first rotating connection part 43, so that the second transport part 42 rotates relative to an axis parallel to the horizontal direction.

[0074] FIG13 shows the waiting state of the transport mechanism 4 , that is, the second transport portion 42 is in a vertical state;

[0075] As shown in Figure 14, the transport mechanism 4 is in the standby state, that is, the second transport part 42 rotates upward to an angle less than 90 degrees with the first transport part 41 to prevent the second transport part 42 from colliding with the reverse support and the slide rail 7. When the transport mechanism 4 moves to the initial engagement position in the standby state, the transport mechanism 4 can be switched to the transport state, that is, as shown in Figure 15, the second transport part 42 is in a horizontal state. At this time, the second transport part 42 can accurately engage with the guide element 5 at the initial engagement position to prevent the engagement position from being offset, which causes the component V to be processed to collide with the lateral edge of each processing unit slot 6 when it rotates, thereby ensuring the safety of the processing process.

[0076] Furthermore, the control module further includes:

[0077] The second detection unit is used to detect whether the transport mechanism 4 at the first position of the upstream station 2 is in the safe switching position. If so, the transport mechanism 4 is controlled to work through the mobile control unit. If not, the transport mechanism 4 is adjusted to the safe switching position.

[0078] Before switching the working state of the transport mechanism 4, the position of the transport mechanism 4 needs to be detected by the second detection unit to ensure that it is in a safe switching position; the safe switching position is a safe switching position where the transport mechanism 4 switches state, that is, when the second transport part 42 changes from vertical to horizontal, there will be no collision with the processing tank; for adjusting the position of the transport mechanism 4, a position adjustment mechanism can be set on the first transport part 41, which can fine-tune the transport mechanism 4 in the direction of the processing path P to ensure the safety of the transport mechanism 4 when switching states.

[0079] In one embodiment, it also includes: a positioning adjustment module, which is used to position the transport mechanism 4 input from the processing path P so that the engagement point between the transport mechanism 4 and the guide element 5 provided on the processing tank is located at an initial engagement position, so that when the transport mechanism 4 moves along the processing path P, under the action of the guide element 5, the component V to be processed is driven to rotate in the horizontal direction along the rotation axis perpendicular to the processing path P.

[0080] During the process of the transport mechanism 4 moving to the initial engagement position in the standby state, the position of the transport mechanism 4 is positioned by the positioning adjustment module to ensure that the second transport part 42 can engage with the guide element 5 at the initial engagement position, thereby ensuring that when moving along the processing path P, the component V to be processed can be accurately flipped to prevent it from colliding with the horizontal frame of the processing unit slot 6, thereby ensuring the safety of the entire processing process and making it proceed in an orderly manner.

[0081] As shown in FIG2 to FIG12 , in one embodiment, the processing tank includes: a plurality of processing unit tanks 6 arranged in sequence, and the guide elements 5 are arranged on both sides of the processing tank along the processing path P;

[0082] When the transport mechanism 4 moves to the initial position of each processing unit slot 6, the engagement of the transport mechanism 4 and the guide element 5 causes the component V to be processed to flip for the first time;

[0083] When the transport mechanism 4 moves to the middle position of each processing unit slot 6, the engagement between the transport mechanism 4 and the guide element 5 causes the component V to be processed to be completely immersed in the processing unit slot 6;

[0084] When the transport mechanism 4 moves to the end position of each processing unit slot 6, the engagement between the transport mechanism 4 and the guide element 5 causes the component V to be processed to be turned over for the second time.

[0085] FIG5 or FIG11 shows the first flipping of the component V to be processed, its complete immersion in the processing unit tank 6, and the second flipping. All of these are caused by the meshing action of the guide portion 421 of the transport mechanism 4 and the guide element 5, so that the component V to be processed completes the above-mentioned actions within one processing unit tank 6, thereby achieving the purpose of processing.

[0086] Of course, this is the effect that can be achieved when the guide portion 421 of the transport mechanism 4 and the guide element 5 are accurately engaged at the initial engagement position.

[0087] In one embodiment, the control module also includes: a third detection unit, which is used to detect whether the component V to be processed is loaded and locked onto the second transport part 42 when the transport mechanism 4 is switched to the conveying state. If so, the transport mechanism 4 is controlled to move along the processing path P through the mobile control unit; if not, the transport mechanism 4 is controlled to be disengaged from the conveying chain 1.

[0088] In this embodiment, in order to prevent the transport mechanism 4 that is not loaded with the component V to be processed from being immersed in the processing liquid, a third detection unit is provided to detect whether the component V to be processed is loaded and locked onto the second transport part 42. At the same time, it can also ensure that the component V to be processed does not fall when it moves and rotates synchronously with the transport mechanism 4, thereby ensuring the stability of the processing process.

[0089] Furthermore, the second transport portion 42 is provided with a locking device, and the component to be processed is provided with a locking hole corresponding to the locking device;

[0090] The present invention also includes: a position detection unit for detecting the position of the locking device inserted into the locking hole, obtaining position information, and a loading mechanism for loading the component V to be processed to adjust the position of the component V to be processed according to the position information so that the position of the locking device inserted into the locking hole reaches a preset position;

[0091] The locking control unit is used to control the locking device and the locking hole to lock when the component V to be processed is loaded on the second transport part 42 and the position of the locking device inserted into the locking hole reaches a preset position; when the component V to be processed arrives at the unloading area, the locking device and the locking hole are unlocked.

[0092] An embodiment of a locking device, the locking device includes a locking body, which is provided with a locking protrusion electrically connected to the locking control unit, and a card hole corresponding to the locking protrusion can be provided on the side wall of the locking hole, and the position detection unit can be provided on the end face of the locking body or any surface that can detect the insertion position of the locking body; when loading, the locking control unit can control the locking protrusion to extend into the card hole when the position of the locking device inserted into the locking hole reaches a preset position to achieve card connection, and then send a loading and locking signal to the third detection unit through the locking control unit, so as to control the transport mechanism 4 to perform the next action through the mobile control unit; when unloading, the locking control unit can control the locking protrusion to withdraw from the card hole, then the lock is released, and the component V to be processed can be detached from the transport mechanism 4 for unloading.

[0093] Through the above design, the loading and locking conditions of the component V to be processed can be detected to ensure effective loading on the transportation mechanism 4 and ensure the locking stability of the component V to be processed.

[0094] In one embodiment, the control module also includes: a fourth detection unit, which is used to detect whether the transport mechanism 4 moving on the processing path P reaches the unloading area. When the transport mechanism 4 reaches the unloading area, the processed component V is unloaded from the transport mechanism 4, and after the transport mechanism 4 is separated from the processing tank, the transport mechanism 4 is switched from the conveying state to the waiting state.

[0095] During unloading, the fourth detection unit is used to detect whether the transport mechanism 4 has reached the unloading area, that is, at the end of the processing unit slot 6 adjacent to the downstream station. At this time, the component V to be processed can be unloaded from the second transport part 42. After unloading is completed, after the transport mechanism 4 is separated from the processing slot, the transport mechanism 4 can switch from the conveying state to the waiting state, and the work cycle is repeated.

[0096] As shown in FIG2 to FIG12 , a component surface treatment device using the transportation system of the present invention includes:

[0097] Two or more processing unit tanks 6 for accommodating processing liquids arranged in series along a processing path P for processing components, wherein the processing unit tanks 6 include two opposite longitudinal sides and two opposite transverse sides, wherein the longitudinal sides extend in the direction of the processing path P and the transverse sides extend in a direction perpendicular to the processing path P;

[0098] a plurality of transport mechanisms 4, each transport mechanism 4 being adapted to hook, support and transport a component V to be processed;

[0099] The conveyor chain 1 includes a first chain drive device for moving the transport mechanism 4 forward along the processing path P, and moving the transport mechanism 4 from the upstream station 2 to the downstream station 3, where the upstream station 2 and the downstream station 3 respectively input and output the transport mechanism 4 from the processing path P; a second chain drive device for moving the transport mechanism 4 from the downstream station 3 back to the upstream station 2;

[0100] wherein the transport mechanism 4 selectively engages with the first chain drive in the upstream station 2, moves along the processing path P in the forward operation, and selectively disengages from the first chain drive;

[0101] The transport mechanism 4 includes: a first transport portion 41, which is coupled to the first chain drive device during movement; a second transport portion 42, which is used to hook, support and transport the component V to be processed, and switches to a transport state when moving along the moving path; the second transport portion 42 is connected to the first transport portion 41 via a first rotating connection portion 43;

[0102] A guide element 5 is arranged on the longitudinal side of the processing tank, and a guide part 421 engaged with the guide element 5 is provided on the second transport part 42. During the movement of the transport mechanism 4 along the processing path P, the transport mechanism 4 corresponding to one or more processing unit tanks 6 is rotated so that the component V to be processed is immersed in the processing liquid of the processing unit tank 6.

[0103] 2 to 12 , the vertical direction is the z-axis, the direction parallel to the processing path P is the x-axis, and the direction perpendicular to the processing path P on the horizontal plane is the y-axis;

[0105] The first type is as shown in Figures 2 to 5, where the conveyor chain 1 is arranged above the processing tank, and the vertical center line of the first transport portion 41 corresponds to the longitudinal side of the processing tank;

[0106] The second type is as shown in Figures 6 to 9, where the conveyor chain 1 is arranged above the processing tank, and the vertical center line of the first transport part 41 corresponds to the horizontal center line of the processing tank (parallel to the processing path P);

[0107] The third type is as shown in FIG. 10 to FIG. 12 , where the conveyor chain 1 is disposed beside the processing tank, and the rotation axis of the first rotary connection portion 43 is the same as the conveying path of the conveyor chain 1 .
