[0002] In a C processing procedure, a product two-dimensional code is bitten by a sanding process, resulting in that IM (injection molding) automatic code scanning cannot be recognized.

[0003] Problems of the existing two-dimensional code protection method:

[0004] 1. Low manual pasting efficiency

[0005] 2. Different manual pasting conditions have large differences, which easily causes a risk that the two-dimensional code is not effectively shielded and corroded by a tank liquid

[0006] 3. Manual pasting easily causes a missing risk

[0007] 4. The tape may fall off during C processing, causing a low two-dimensional code corrosion recognition rate

[0008] 5. The tape is a one-time consumable, and has large loss.

[0009] Therefore, an inventor designs a hanger shielding tool, application number CN201420064894.6, which is fixed to a ground chain.

Detailed Implementation

[0040] The following are specific embodiments of the invention, which are described in conjunction with the accompanying drawings. The technical solution of the invention will be further described, but the invention is not limited to these embodiments. Example 1

[0041] like Figure 1 As shown, this hanging device with shielding function includes a hanging frame 1, which includes several vertical beams and several horizontal beams. At least one workpiece clamping station is formed between two adjacent upper and lower horizontal beams.

[0042] Specifically, such as Figures 1-3 As shown, at least one lower support member 2 is provided on the hanging bracket 1. An upper elastic pressing member 3, located above the lower support member 2, is also provided on the hanging bracket 1. The upper elastic pressing member 3 is formed by bending a piece of elastic metal sheet. When not compressed, the upper elastic pressing member 3 is in a horizontal V-shape; when compressed, it is in a horizontal U-shape. In both V- and U-shaped states, the upper end of the upper elastic pressing member 3 is horizontally positioned. The upper end of the upper elastic pressing member 3 is fixed to the hanging bracket 1, while the lower end is free. The free end of the upper elastic pressing member 3 has an upwardly bent and laterally extended control part 31. Each lower support member 2 is provided with an elastic arm 4. A shielding member 5 with a horizontal contact surface 50 on its upper surface is connected to the suspended end of the elastic arm 4. The horizontal contact surface 50 is flush with the workpiece support surface of the lower support member 2.

[0043] The workpiece is clamped and fixed between the upper elastic pressing piece 3 and the lower supporting piece 2, and the upper elastic pressing piece 3 has a certain elastic property, which not only meets the requirement of firm clamping and fixing, but also facilitates the disassembly of the workpiece, greatly improves the disassembly efficiency, and improves the production capacity.

[0044] The identification code is arranged on the workpiece supporting surface of the lower supporting piece 2. When the horizontal contact surface 50 is flush with the workpiece supporting surface of the lower supporting piece 2, the horizontal contact surface 50 of the shielding piece 5 contacts and covers the identification code of the workpiece. The shielding piece 5 has a tendency to always move upward under the elastic action of the elastic arm 4, so that the horizontal contact surface 50 is forced to be in a horizontal state when contacting the identification code of the workpiece, to ensure that the identification code is always fully covered by the shielding piece 5 during the C processing, preventing the phenomenon of incomplete or inadequate covering.

[0045] Specifically, as shown in Figure 3 The lower supporting piece 2 of the embodiment is in a U shape, and the lower positioning groove 20 is arranged at each end of the lower supporting piece 2. The free section of the upper elastic pressing piece 3 is provided with an upper clamping groove 30 with a downward notch. The lower positioning groove 20 and the upper clamping groove 30 form positioning of the workpiece in the up-down direction and the thickness direction, and form a triangular fixing mode, so that the workpiece is fixed more stably. The lower supporting piece 2 is made of a metal plate bent, which has low efficiency and good consistency. A plurality of lower supporting pieces 2 can be installed on the hanging device of the embodiment to ensure the consistency of each clamping station.

[0046] The design of the two lower positioning grooves 20 can form multi-point supporting of the lower side of the workpiece, so that the workpiece is fixed more firmly.

[0047] The horizontal contact surface 50 is flush with the groove bottom workpiece supporting surface of the lower positioning groove 20. The flush of the two can ensure that the identification code is always fully covered by the shielding piece 5, preventing the phenomenon of incomplete or inadequate covering. Secondly, when the workpiece is placed in the lower positioning groove 20, the free end of the elastic arm 4 is deformed downward due to the weight of the workpiece. When the horizontal contact surface 50 is in line with the lower side surface of the workpiece, it indicates that the identification code on the workpiece is fully covered.

[0048] The reverse covering or shielding in this elastic mode can ensure that the identification code is fully covered throughout the process, ensuring the integrity of the identification code.

[0049] The elastic arm 4 of the embodiment is connected to the bottom of the U-shaped groove of the lower supporting piece 2 at one end, and the other end of the elastic arm 4 is extended upward to the middle of the U-shaped groove and is in a free state. The shielding piece 5 is fixed to the free end of the elastic arm 4.

[0050] And the elastic arm 4 comprises a first flat section 40 fixed on the bottom of the U-shaped groove, an inclined section 41 connected on the first flat section 40, a second flat section 42 connected on the upper end of the inclined section 41, and the shielding member 5 is fixed on the second flat section 42, the first flat section 40 and the second flat section 42 are distributed at an acute angle, and the second flat section 42 and the horizontal contact surface 50 are distributed at an acute angle, that is, when the identification code is completely covered, the second flat section 42 at this time is in an inclined state, the inclined direction is from top to bottom to the inclined section 41 side, and the shielding member 5 is made of silica gel material, so that the shielding member 5 is lowered to completely cover the identification code under the elastic effect of the elastic arm 4 and the elastic effect of the shielding member 5 itself.

[0051] As shown in Figure 7 , the shielding member 5 is provided with a flat positioning hole 51 for inserting the free end of the elastic arm 4. A C-shaped spring 420 distributed in a rectangular ring is arranged on the upper surface of the second flat section 42, the length of the rectangular ring is longer than the length of the identification code, and the width of the rectangular ring is longer than the width of the identification code, and the upper end of the C-shaped spring 420 abuts against the upper hole wall of the flat positioning hole. In the shielding state, since the shielding member 5 is made of silica gel material, when the identification code is fitted with the horizontal contact surface 50, the C-shaped spring 420 at this time forces the horizontal contact surface 50 to form an upward bulge on the plane except the plane in contact with the identification code, thereby playing a further sealing role. Further, a rectangular groove is arranged on the upper hole wall of the flat positioning hole 51, and the upper end of the C-shaped spring 420 abuts against the groove bottom of the rectangular groove, so as to prevent the C-shaped spring 420 from damaging the flatness of the horizontal contact surface 50. The elastic force of the C-shaped spring 420 is smaller than the elastic force of the elastic arm 4.

[0052] Secondly, as shown in Figures 1-3 , a limiting block 7 is arranged below the free end of the elastic arm 4 at the bottom of the U-shaped groove. The limiting block 7 can limit the excessive downward deformation of the elastic arm 4. Embodiment two

[0053] As shown in Figures 1-7 , the present embodiment provides an operating method of a hanging device, the operating method of the hanging device adopts the hanging device with shielding function of the embodiment one, and the operating method of the hanging device comprises the following steps:

[0054] S1, the identification code on the lower side of the workpiece is directed to the horizontal contact surface 50 of the shielding member 5;

[0055] When the upper elastic pressing member 3 is pressed to the compressed state, the U-shaped opening of the upper elastic pressing member 3 is smaller than the bottom diameter of the U-shaped opening;

[0056] S2, the lower side of the workpiece in S1 is placed on the workpiece supporting surface of the lower supporting member 2, and the contraction force of the upper elastic downward pressing member 3 in S1 is cancelled, so that the upper elastic downward pressing member 3 is pressed downward to the upper side of the workpiece, and when the workpiece is pressed, the horizontal contact surface 50 and the identification code are in contact, and the surface area of the horizontal contact surface 50 is larger than that of the identification code, so that the shielding member 5 covers the identification code completely;

[0057] The workpiece clamping is completed by S1-S2 above;

[0058] S3, after the corresponding treatment is completed, the upper elastic downward pressing member 3 in S2 is contracted again, and then the workpiece after processing is taken out. The corresponding treatment is, for example, sanding, etc.

Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
