Description

Technical Field

[0001] This utility model relates to the field of body-in-white welding technology, specifically to a positioning device for a fixture storage location and its flexible body-in-white welding line. Background Technology

[0002] Body-in-white refers to the steel or aluminum alloy frame structure of a vehicle, which forms the overall framework of the vehicle and provides structural strength and support. This undecorated body structure usually presents its original metallic color, hence the name "body-in-white".

[0003] Although body-in-white welding technology has gradually matured and largely achieved automation, there are still some shortcomings in the convenience of switching between precision positioning equipment locations. This is because existing automated production lines are increasingly developing towards flexibility, multi-model switching, and reduced human intervention, therefore the tooling within the line needs to meet the switching requirements of multiple vehicle models.

[0004] However, existing flexible production solutions mainly include robot switching, turntable rotation switching, and manual switching of warehouse locations. Some of these solutions have the problem of excessively high costs for integrating multiple models into the production line, while others have the problem of complex operation during the integration of multiple models into the production line, which cannot meet the needs of the debugging and transition period. This affects the utilization efficiency of the welding line and increases the cost of car manufacturing.

[0005] Therefore, it is crucial to research a positioning mechanism that can ensure precise tooling positioning and switching during the early stages of online body debugging, while simultaneously fulfilling the dual functions of manual and AGV transport. Utility Model Content

[0006] In a first aspect, to solve the above-mentioned technical problems, this utility model provides a positioning device for a clamp storage location, comprising:

[0007] A ground positioning assembly arranged horizontally along the fixture storage location includes a coarse ground guide unit and a fine ground guide unit; the coarse ground guide unit guides the fixture into the fixture storage location; the fine ground guide unit can gradually correct the movement trajectory of the fixture as it enters the fixture storage location.

[0008] The clamp positioning assembly arranged vertically along the clamp storage position includes a first lifting cylinder unit capable of moving up and down and a second lifting cylinder unit capable of moving axially; the two ends of the second lifting cylinder unit are respectively connected to the first lifting cylinder unit; the clamp positioning assembly is activated to match and connect with the clamp, and the clamp storage position is switched accordingly.

[0009] Furthermore, the positioning mechanism has an axisymmetric structure; the ground coarse guide unit is set on the ground and has a door frame structure, and the opening of the ground coarse guide unit is outwardly flared.

[0038] To make the technical solutions and effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0039] The first aspect of this utility model aims to provide a positioning device for a fixture storage location, which is adapted to allow fixtures to be transferred to the fixture storage location 000 by either manual or AGV transport.

[0040] Please see Figure 1 The positioning mechanism has an overall axisymmetric structure, which mainly includes a ground positioning component and a clamp positioning component. An energy plate 300 is also installed on the clamp storage position 000.

[0041] First, the ground positioning component in this embodiment will be described.

[0042] The ground positioning assembly is arranged horizontally along the fixture storage location 000. The ground positioning assembly along the fixture storage location 000 includes a ground coarse guide unit 110, a ground fine guide unit 120, and a sensor 130.

[0043] In a further embodiment, the ground coarse guide unit 110 is installed on the ground and has a door frame structure; the opening of the ground coarse guide unit 110 is outwardly flared. The purpose of designing the ground coarse guide unit 110 is to guide the clamp from the opening end of the ground coarse guide unit 110 into the clamp storage position 000 when the clamp is manually pushed into the clamp storage position 000.

[0044] For further details, please refer to [link / reference]. Figure 2 The ground precision guide unit 120 includes a first guide side plate 121, a second guide side plate 122, and a third guide side plate 123. The first guide side plate 121, the second guide side plate 122, and the third guide side plate 123 are sequentially and continuously arranged on the inner side wall of the fixture storage position 000 away from the opening end of the ground coarse guide unit 110, and can contact the fixture.

[0045] Along the horizontal direction from the ground coarse guide unit 110 into the fixture storage position 000, the thickness of the first guide side plate 121, the second guide side plate 122, and the third guide side plate 123 increases progressively. The purpose of this design for the ground fine guide unit 120 is to allow it to gradually correct the movement trajectory of the fixture into the fixture storage position 000 when the fixture is manually pushed into the fixture storage position 000.

[0046] Preferably, the thickness ratio of the first guide side plate 121, the second guide side plate 122 and the third guide side plate 123 is 3:4:5.

[0047] In this embodiment, the thickness of the first guide side plate 121 can be 15mm, the thickness of the second guide side plate 122 can be 20mm, and the thickness of the third guide side plate 123 can be 25mm, but it is not limited to these.

[0048] Depend on Figure 2 As can be seen from the structure of the ground precision guide unit 120 shown, the first guide side plate 121, the second guide side plate 122 and the third guide side plate 123 are each provided with ramps at both ends. This design is conducive to manually pushing the clamp.

[0049] In a further embodiment, sensor 130 is positioned at the end of the fixture storage location furthest from the opening of the ground-level coarse guide unit 110, i.e., sensor 130 is located on the same side as the energy plate 300. Sensor 130 is connected to a sensor indicator light. When the fixture is manually pushed into the fixture storage location, sensor 130 detects that it has reached the designated position, the sensor indicator light illuminates, and the fixture positioning assembly then performs the relevant actions.

[0050] Next, the clamp positioning component in this embodiment will be described.

[0051] Please see Figure 2-4 The fixture positioning component is arranged vertically along the fixture storage position 000. The movement of the fixture positioning component causes the fixture positioning component to match and connect with the fixture, and the fixture storage position 000 is switched accordingly.

[0052] The clamp positioning assembly includes a first lifting cylinder unit 210 capable of vertical movement, a second lifting cylinder unit 220 capable of axial movement, and a guide plate 230. The two axial ends of the second lifting cylinder unit 220 are respectively connected to the first lifting cylinder unit 210.

[0053] In a further embodiment, a positioning pin 211 is provided on the top of the first lifting cylinder unit 210. The positioning pin 211 has a pointed tip for engaging with a positioning hole at the bottom of the fixture.

[0054] In a further embodiment, the second lifting cylinder unit 220 includes a connecting rod 221 and a support platform 222 fixedly connected to both ends of the connecting rod 221.

[0055] A drive motor is mounted on the side of the connecting rod 221 that is away from the clamp.

[0056] The through support platform 222 is provided with a first circular hole 222a and a second circular hole 222b. The first circular hole 222a and the second circular hole 222b are connected, and the diameter of the first circular hole 222a is larger than the diameter of the second circular hole 222b.

[0057] Further described, the combination of the first circular hole 222a and the second circular hole 222b forms a gourd-shaped structure.

[0058] Those skilled in the art will understand that the axial movement of the second lifting cylinder unit 220 can drive the connecting rod 221 to move axially, so that the first lifting cylinder unit 210 can be switched from the first circular hole 222a to the second circular hole 222b.

[0059] In a further embodiment, the guide plates 230 are positioned opposite each other and perpendicular to the ground coarse guide unit 110. The purpose of this design is that when the fixture is transferred to the fixture storage location by AGV transport, the guide plates 230 can guide the fixture.

[0060] Finally, the energy plate mechanism in this embodiment will be described.

[0061] Please see Figure 5 The energy plate mechanism includes an energy plate 300, which is located at the end of the clamping station away from the opening of the ground coarse guide unit 110. The male end of the energy plate 300 extends out and can match the female end carried by the clamp to switch the clamp.

[0062] Since the male end of the energy plate protrudes and matches the female end on the fixture in the quick-change fixture system, which is a fairly conventional structure for quick fixture replacement, the specific structure of the energy plate 300 in this embodiment will not be described in detail.

[0063] A second aspect of this utility model aims to provide a flexible welding line for a body-in-white, the welding line including the aforementioned positioning device for the fixture storage position.

[0064] This embodiment can switch between manual and AGV-based precise positioning. During operation:

[0065] When manually switching fixtures, the manual pushes the fixture along the ground coarse guide unit 110 into the fixture storage position 000. When the sensor 130 detects that the fixture has reached the designated position of the fixture storage position 000, the sensor indicator light lights up, and the first lifting cylinder unit 210 extends out from the first circular hole 222a. After the second lifting cylinder unit 220 retracts, the first lifting cylinder unit 210 also retracts, and the second lifting cylinder unit 220 falls to the working position to play the role of precise positioning of the fixture.

[0066] When the AGV switches grippers, after the AGV transports the gripper to the designated position, the first lifting cylinder unit 210 switches to the working position first, and the AGV slowly descends. At the same time, the positioning pin 211 matches the positioning hole at the bottom of the gripper to assist in the landing, thereby realizing the precise positioning and switching of the AGV.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
