Description

Technical Field

[0001] This utility model relates to the field of conveyor control technology, and in particular to a reliable transfer system for a door component. Background Technology

[0002] In existing automobile assembly lines, body transfer equipment is essential for transferring body parts or body components between different lines. Typically, door components are placed in door skids and transported and stored via roller bed lines. In the door process section, door components, along with door skids, are placed in door hangers and transported via friction-driven lines.

[0003] However, during the transfer of the door components from the roller bed line to the friction drive line, if the door skid fails to land accurately on the door hanger's support arm due to inaccurate positioning or the transfer equipment not being in place, it may lead to transfer abnormalities. If the transfer continues under these circumstances, at best, interference between the equipment and the vehicle body components may occur, causing damage to the equipment and the vehicle body; at worst, it may pose a serious threat to the personal safety of the operators. Summary of the Invention

[0004] Therefore, this utility model provides a reliable transfer system for vehicle door components, which can accurately detect whether the door skid lands accurately on the support arm of the door hanger during transfer. It is non-contact and has the advantages of long service life and high detection accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides a reliable transfer system for vehicle door components, comprising: A transplanting mechanism is movable within the transfer area, and the transplanting mechanism includes a lifting unit; A door skid is placed on the lifting unit. The door skid is loaded with a door component to be transferred. The door skid includes a support base plate and two vertical arms disposed on the support base plate. Each vertical arm is provided with a detection plate and a positioning pin installed on the detection plate and extending in the vertical direction. The conveying mechanism is movably positioned above the transfer area; A door hanger is mounted on the conveying mechanism. The door hanger has a pair of support arms extending vertically, a support arm horizontally disposed at the bottom of each support arm and capable of docking with the support base plate, and a positioning block capable of engaging with the positioning pin. The testing mechanism includes two sets of photoelectric detection units, each set of photoelectric detection units being used to detect the position of each of the detection plates; When both the door hanger and the door skid are transported to the transfer point within the transfer area, the lifting unit descends, the door skid is transferred to the door hanger, and the detection mechanism checks whether the transfer is in place.

[0006] In one embodiment of this utility model, each of the photoelectric detection units includes a through-beam photoelectric switch.

[0007] In one embodiment of this utility model, each of the photoelectric detection units is installed in the transfer area by a bracket, and the two corresponding photoelectric switches are located on both sides of the transfer point along the moving direction of the transplanting mechanism.

[0008] In one embodiment of this utility model, the two corresponding photoelectric switches are not on the same horizontal plane.

[0009] In one embodiment of this utility model, a PLC controller is also included, which is electrically connected to the transplanting mechanism, the conveying mechanism and the detection mechanism.

[0010] In one embodiment of this utility model, the transplanting mechanism is a chain transplanter, and the lifting unit is a lifting roller bed.

[0011] In one embodiment of this utility model, the conveying mechanism is a friction conveyor.

[0012] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a reliable transfer system for vehicle door components. By installing a detection plate and positioning pin on the vertical arm of the door skid and a positioning block on the support arm of the door hanger, it ensures proper mating between the door skid and the door hanger. This accurately detects whether the door skid lands precisely on the support arm of the door hanger during transfer, preventing transfer failures due to misalignment. The detection mechanism accurately detects the actual position of the door skid and is non-contact, offering advantages such as long service life and high detection accuracy. It also significantly reduces wear on detection components, improving the safety and stability of the system. Furthermore, it has a simple structure and is easy to install.

[0013] The detection mechanism of this utility model adopts two sets of through-beam photoelectric switches, and the corresponding photoelectric switches are arranged on different horizontal planes to avoid interference with the grating, the hanger or the skid.

[0014] This utility model is equipped with a PLC controller to control the transplanting mechanism, conveying mechanism, and inspection mechanism. Through PLC logic judgment, after the door skid and the lifting device are aligned, the entire process of lifting, lowering, transferring, and inspection can be completed automatically, effectively improving the intelligence and automation level of the production line.

[0025] Reference Figure 1 As shown, the present invention provides a reliable transfer system for a vehicle door component, comprising: Transplanting mechanism 1 is movable within transfer area 8, and the transplanting mechanism 1 includes lifting unit 11; The door skid 2 is placed on the lifting unit 11. The door skid 2 is loaded with the door component 3 to be transferred. The door skid 2 includes a support base plate 21 and two vertical arms 22 set on the support base plate 21. Each vertical arm 22 is provided with a detection plate 23 and a positioning pin 24 installed on the detection plate 23 and extending in the vertical direction. The conveying mechanism 4 is movably positioned above the transfer area 8; The door hanger 5 is installed on the conveying mechanism 4. The door hanger 5 has a pair of support arms 51 extending in a vertical direction, a support arm 52 horizontally arranged at the bottom of each support arm 51 and capable of docking with the support base plate 21, and a positioning block 53 capable of engaging with the positioning pin 24. The testing mechanism includes two sets of photoelectric detection units 6, each set of photoelectric detection units 6 being used to detect the position of each of the detection plates 23; When both the door hanger 5 and the door skid 2 are transported to the transfer point within the transfer area 8, the lifting unit 11 descends, the door skid 2 is transferred to the door hanger 5, and the detection mechanism checks whether the transfer is in place.

[0026] In one embodiment, each of the photoelectric detection units 6 includes a through-beam photoelectric switch 61.

[0027] Specifically, each of the photoelectric detection units 6 is installed in the transfer area 8 by a bracket, and the corresponding two photoelectric switches 61 are located on both sides of the transfer point along the moving direction of the transplanting mechanism 1.

[0028] Specifically, the two corresponding photoelectric switches 61 are not on the same horizontal plane to avoid interference with the grating, door hanger 5 and door skid 2 arranged in the transfer area 8.

[0029] In one embodiment, refer to Figure 2 As shown, it also includes a PLC controller 7, which is electrically connected to the transplanting mechanism 1, the conveying mechanism 4, and the detection mechanism. Specifically, the photoelectric switch 61 is connected to the PLC controller 7 via a field input module 71.

[0030] In one embodiment, refer to Figure 3 , Figure 4 As shown, the transplanting mechanism 1 is a chain transplanter, and the lifting unit 11 is a lifting roller bed. It should be noted that the chain transplanter and the lifting roller bed are common existing structures. Exemplarily, the chain transplanter is installed on two parallel guide rails within the transfer area 8, and includes a drive motor 12, multiple parallel drive shafts 13, and parallel double-row chains. The drive shafts 13 are equipped with moving wheels and sprockets, and the chains are wound around the sprockets. Driven by the drive motor 12, each drive shaft 13 rotates, thereby moving the moving wheels along the guide rails. A hydraulic cylinder, pneumatic cylinder, or electric screw lifting mechanism can be used to raise or lower the lifting roller bed. When raised, the rollers of the lifting roller bed protrude above the plane of the chain transplanter; when lowered, the rollers are below the plane.

[0031] In one embodiment, the conveying mechanism 4 may be a friction conveyor. It should be noted that friction conveyors are a common structure in the prior art. Exemplarily, a friction conveyor includes a reduction drive motor 41 mounted on both sides of a track and a friction drive roller 42 connected thereto. The door hanger 5 is suspended below the track by a roller hanger 43. When the friction drive roller 42 rotates under the action of the reduction drive motor 41, its surface generates friction with the contact surface of the roller hanger 43. This friction force propels the door hanger 5 to move along the conveying direction, achieving a conveying method without chains or rigid traction elements.

[0032] The transplanting mechanism 1 adopts a chain transplanter, and the lifting unit 11 adopts a lifting roller bed. By adopting mature and reliable existing structures, it has strong load-bearing capacity and stable operation. The conveying mechanism 4 adopts a friction conveyor, which has low noise, low vibration, and simple maintenance, and is suitable for the flexible transfer of the door hanger 5.

[0033] The working principle of this utility model is as follows: First, the PLC controller 7 controls the conveyor mechanism 4 to move the unloaded door hanger 5 along the track to the predetermined transfer point, where it is positioned and waiting. Subsequently, the PLC controller 7 controls the lifting unit 11 of the transplanting mechanism 1 to be in the lifting state, and the door skid 2 carrying the door component 3 is transported to the transfer point position through the transplanting mechanism 1. When the door skid 2 moves to the transfer point, the PLC controller 7 controls the lifting unit 11 to descend, so that the door skid 2 accurately lands on the support arm 52 of the door hanger 5, and the positioning is achieved by the insertion of the positioning pin 24 and the positioning block 53. During this process, the through-beam photoelectric switch 61 in the detection mechanism detects the position and alignment status of the skid in real time and transmits the signal to the PLC controller 7. If the detection result indicates that the transfer is successful (i.e., two detection boards 23 are detected), the PLC controller 7 will control the transfer mechanism 1 to return to the receiving point, and at the same time control the conveying mechanism 4 to drive the door hanger 5 into the subsequent process section. If the detection result indicates that the transfer is unsuccessful, the PLC controller 7 will immediately issue an alarm signal to remind the operator to handle the situation in time and avoid equipment damage or safety accidents.

[0034] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
