DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0033] As Figures 1 - 5 shown, an automatic receiving device for realizing the automatic collection of inner door panel parts of a door without a manipulator includes the following components:

[0034] Flip Bracket 1: It is used for the flip - bearing of the inner door panel parts. Its main components include: a bracket base 101, which is a base formed by welding square steel pipes; bracket vertical rods 102 are two vertical square steel pipes, which are connected to the bracket base 101 by welding; there is a strengthening cross - bar 103 between the two bracket vertical rods 102 for lateral strengthening.

[0035] Further, the top - plate rotating shaft 104 is located at the rear side of the two bracket vertical rods 102 (defining the direction of the feeding - line movement as the rear side). It is respectively provided with top - plate rotating shafts 104 parallel to the strengthening cross - bar 103; the top - plate rotating shaft 104 is connected to the bracket vertical rod 102 through a direction steel pipe perpendicular to the bracket vertical rod 102. Its end is a rotating part that cooperates with the top - plate bushing 4 for realizing the rotation of the top - plate bushing 4 and the top - plate 3. On the rotating part, limit card slots 105 are respectively arranged at both ends of the top - plate bushing 4, and the position of the top - plate bushing 4 is restricted by the limit card slots stuck in the slots. At the front side of the top - plate rotating shaft 104, a top - plate limit rod 109 is provided for limiting the rotation stroke of the top - plate 3.

[0036] Further, a limit cross - bar 107 parallel to the strengthening cross - bar 103 is provided at the top and front side of the flip bracket 1. The limit cross - bar 107 is used for controlling the rotation stroke (angle) limit of the rotating table plate 2; a return - stroke limit block 108 is provided at the top of the flip bracket 1. After the rotating table plate 2 rotates back, its bottom plate 201 abuts against the return - stroke limit block 108 for realizing the return - stroke limit of the rotating table plate 2. By adjusting the height of the return - stroke limit block 108, the initial angle position of the rotating table plate 2 can also be adjusted.

[0037] Further, a rotating - table rotating shaft 106 is also provided at the top of the bracket vertical rod 102. Its end is also provided with a rotating part, and the rotating part cooperates with the rotating - table bushing 501 for realizing the rotation movement of the rotating table plate 2. Limit card slots are respectively arranged at both ends of the rotating - table bushing 501 on the rotating part, and the position of the rotating - table bushing 501 is restricted by the limit card slots stuck in the slots.

[0038] Rotating Table Plate 2: The bottom plate 201 is a common steel plate, and side guard plates 202 are connected by welding on both sides, playing a role in limiting the inner door panel and preventing it from slipping to both sides.

[0039] Further, a buffer - support soft plate 203, which is a stamping plate with a relatively thin thickness, is connected to the bottom plate 201 by bending and welding. Multiple support soft plates are arranged in the middle, and the whole has a certain elasticity, which can play a buffer - support role after the inner door panel moves onto the rotating table plate, avoiding large collision deformations caused by completely rigid support.

[0040] Further, a limit plate 204 is perpendicularly welded to the bottom end of the bottom plate 201 for rotating - downward limit. The bottom plate 201 is also provided with a top - plate through - hole 205 for the rotation of the top - plate 3 to pass through.

[0041] Top plate 3: It is generally in an "L" - shaped structure, and the bent part of the acute - angled corner is arc - shaped; in the middle of the longer end, a top - plate bushing 4 is installed through welding. In the initial state, as Figure 4 shown, when the inner door panel and the rotary table plate 2 rotate together by a certain angle, they start to contact the long - side end of the top plate 3 and press it down to make it move around the top - plate rotating shaft 104. The other end of the top plate 3 rotates and extends into the top - plate through - hole 205, contacts the inner door panel, and pushes the upper part of the inner door panel to rotate around the bottom edge against the limiting plate 204, so that the upper part of the inner door panel disengages from the rotary table plate and rotates onto the guide slide plate 803. Subsequently, due to gravity and inertia, the inner door panel slides into the special work - piece fixture, reaching the state as Figure 3 shown.

[0042] Top - plate bushing 4: It is connected to the top plate 3 through welding.

[0043] Rotary connecting piece 5: One end is welded with a rotary - table bushing 501, and the other end is fixedly installed on the bottom plate 201.

[0044] Rotary - table limiting plate 6: One end is fixedly installed on the bottom plate 201. It is used to limit the rotation stroke of the rotary table plate 2 downward through the limiting cross - bar 107. The other end is fixedly connected with a counterweight 7. By adjusting the weight of the counterweight 7, the overall center of gravity of the rotary table plate 2 is controlled, and after the inner door panel disengages, the whole rotary table plate 2 can return to its original position.

[0045] Work - piece fixture 8: A special work - piece fixture for storing the inner door panel. It is provided with a storage hanging rod 802, and the inner door panel is stored by passing through the window - frame hole of the inner door panel. One end of the storage hanging rod 802 is welded and fixedly connected to the support 801, and the other end is fixedly connected with a guide slide plate 803.

[0046] Furthermore, the guide slide plate 803 and the storage hanging rod 802 are set at a certain angle, which can make the inner door panel slide and fall onto the storage hanging rod 802. A protective soft plate 804 is also fixedly installed on the guide slide plate 803, which is used to buffer when the inner door panel rotates and falls, reducing collision deformation. The cross - section of the guide slide plate is set to be a structure conforming to the shape of the car window frame, avoiding point - contact during the guiding process and reducing deformation during the sliding process.

[0047] Furthermore, the protective soft plate 804 is composed of three (or more) thin stamping plates stacked and installed, and there are gaps between the thin plates, which can buffer and shock - absorb when the inner door panel rotates and falls, reducing collision deformation.

[0048] The production and receiving process using the automatic receiving device of this application is as follows:

[0049] As Figure 4As shown, in the initial state, the rotary table plate 2 is approximately horizontal and slightly lower than the height of the conveyor belt 9. After the inner door panel parts are produced, they are transported by the conveyor belt and gradually move onto the rotary table plate 2. When the inner door panel 10 is transported a certain distance, the center of gravity of the inner door panel parts on the rotary table plate 2 gradually moves outward as a whole. When the center of gravity exceeds the rotary table shaft 106, the rotary table plate 2 starts to rotate. The inner door panel 10 slides downward along the bottom plate 201, and the position of the downward movement is controlled by the limit plate 204 to reach Figure 1 the position state of the inner door panel shown by the solid line as shown.

[0050] After the rotary table plate 2 rotates a certain distance, it contacts one end of the top plate 3 and pushes the top plate 3 to rotate. The other end of the top plate 3 extends into the top plate through hole 205, abuts against the upper part of the inner door panel 10 and pushes the inner door panel to rotate. At the same time, due to the center of gravity and inertia, the inner door panel will rotate along the edge abutting against the limit plate 204 to reach as Figure 1 shown by the position state of the inner door panel shown by the dashed line. During the rotation process, the rotary table plate 2 controls the rotation stroke through the cooperation of the rotary table limit plate 6 and the limit cross bar 107 installed on the back.

[0051] As Figure 1 , Figure 5 shown, the upper frame of the rotated inner door panel rests on the protective soft plate 804 on the guide slide plate 803, and then slides downward to the storage hanging rod 802.

[0052] When the inner door panel detaches from the rotary table plate 2, the rotary table plate 2 realizes reverse rotation and return to the original position under the action of its own center of gravity and the counterweight block 7, and the return limit is controlled by the return limit block 108. The top plate 3 detaches from the rotary table plate 2 and also rotates and returns to the original position around the top plate shaft 104 under the action of gravity, and is limited by the top plate limit plate 109.

[0053] Although the present invention has been disclosed as above with embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different selections and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is defined by the claims and their equivalent forms.
