Description

Technical Field

[0001] The utility model relates to the field of household appliance assembly equipment, in particular to a servo torsion cup positioning mechanism for household appliances. Background Art

[0002] In existing household appliances such as kettles, wall breakers, meat grinders, etc., they generally consist of a cup body and a base. The common connection methods between the cup body and the base are screw connection and snap connection. When using snap connection, a downward pressure needs to be applied to the cup body and the base by equipment to make them snap together tightly.

[0003] For example, in a Chinese patent: the application number is 2017114102377, and the patent name is a device for realizing downward pressure by using a cylinder, "including a pressure gauge connecting block, a pressure sensor, a pressing head, a cylinder, a cylinder fixing plate and a pressure gauge fixing plate; the cylinder is arranged on the cylinder fixing plate; a pressure gauge connecting block is arranged below the pressure gauge fixing plate, and the cylinder is connected to the pressure sensor through the pressure gauge connecting block; a pressing head is arranged below the pressure sensor". In the above technology, a downward pressure is applied to the workpiece to be assembled below by the cylinder to connect the workpieces below the cylinder together. However, the production of household appliances now requires standardization. For example, there will be components such as a charging plug, buttons or a display screen on the base. After the base and the cup body are assembled, the above components need to be in the same position as the components on the cup body. For example, using the cup handle of the cup body as a positioning point, the charging plug on the base needs to be perpendicular to the cup handle, and the display screen and buttons are perpendicular to the other side away from the cup handle. If the cup body and the base are directly connected together by the cylinder, without a positioning mechanism, after the cup body and the base are connected together, it is impossible to ensure that the components of each cup body and the base in the same batch of products are in the same position.

[0037] A pressing mechanism 20, a bracket 11 is provided on the workbench 1, and a pressing mechanism 20 that can press the cup body and the bottom fittings together is provided above the base 2 on the bracket 11.

[0038] Further embodiment of the annular seat 6 in the present utility model: The annular seat 6 includes support rods 61 symmetrically arranged on the top of the rotating ring 4. A circular ring 62 is fixed to the top of the support rods 61. A plurality of arc-shaped plates 63 are sequentially arranged along the circumference on the top of the circular ring 62. Arc-shaped elastic plates 64 extend from the top of the arc-shaped plates 63 towards the axis of the circular ring 62. In the initial state, the cup body is placed on the arc-shaped elastic plates 64. There is a gap between the cup body placed on the arc-shaped elastic plates 64 and the cup body base on the fixture 7. In this way, when the annular seat 6 rotates, it will not interfere with the cup body base. When the second air cylinder 21 presses down to connect the cup body with the cup body base, the arc-shaped plates 63 and the arc-shaped elastic plates 64 will deform, so that the cup body moves downward and is connected with the cup body base together.

[0039] Further embodiment of the arc-shaped plate 63 in the present utility model: An annular rubber sleeve 65 is sleeved on the arc-shaped plates 63 and the arc-shaped elastic plates 64.

When the cup handle contacts the positioning plate 24, the cup handle is equivalent to being moved to the set correct position.

[0045] Further embodiment of the bracket 11 of the present utility model: A vision sensor 25 for detecting the position of the cup body is provided on the bracket 11.

[0046] Further embodiment of the workbench 1 of the present utility model: A two-hand start button 26 is provided on the workbench 1.

[0047] During use: In the initial state, the cup body is placed on the arc-shaped elastic plate 64. There is a gap between the cup body placed on the arc-shaped elastic plate 64 and the cup body base on the fixture 7, so that when the annular seat 6 rotates, it will not interfere with the cup body base. When the second cylinder 21 presses down to connect the cup body to the cup body base, the arc-shaped plate 63 and the arc-shaped elastic plate 64 will deform, so that the cup body moves downward and is connected to the cup body base. The annular rubber sleeve 65 can prevent the cup body from being scratched or damaged by the arc-shaped plate 63 and the arc-shaped elastic plate 64 when the cup body moves downward. Process positioning points are provided on the cup body base. The cooperation between the process positioning points and the positioning holes 74 can ensure that after the cup body is connected to the cup body base, components such as the charging plug, button or display screen are in the same position. When the cup body is placed on the annular seat 6, the vision sensor 25 will detect whether the cup handle on the cup body is in the specified position. If the cup handle is not in the specified position, when the worker presses the two-hand start button 26, the drive motor 81 will be activated first to rotate the cup handle on the annular seat 6 to the specified position, and then the second cylinder 21 will be activated to press down to connect the cup body and the cup body base. When the vision sensor 25 detects that the cup handle is in the correct position, the first cylinder 92 will be activated to press the arc friction block 93 against the annular top plate 91, so that the annular seat 6 cannot rotate. After the arc friction block 93 is pressed against the annular top plate 91, the second cylinder 21 will be activated to move the pressure plate 22 downward to connect the cup body to the cup body base. When the cup handle contacts the positioning plate 24, the cup handle is equivalent to being moved to the set correct position.
