Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically relating to a tooling for bonding sheet metal parts to panels. Background Technology

[0002] Currently, most glass panel bonding components used in the kitchen appliance industry consist of one or more sheet metal parts bonded to the glass panel. Some of these sheet metal parts have the same thickness, while others have different thicknesses. When sheet metal parts of different thicknesses are bonded to one side of the same piece of glass at the same time, the sheet metal parts with thicker walls will make contact with the glass panel first, while the sheet metal parts with thinner walls will not make contact with the glass panel, resulting in the failure of bonding the thin sheet metal parts.

[0003] To solve the above technical problems, there are currently two main approaches: one is to fix the sheet metal parts and bond them in multiple stages, that is, first bond a sheet metal part of one thickness to the glass panel, then bond a sheet metal part of another thickness to the glass panel, and so on, to ensure that the glass is bonded; the other is to fix the glass panel and bond sheet metal parts of different thicknesses to the glass panel, thereby ensuring that all sheet metal parts are bonded to the glass panel.

[0004] Existing bonding technologies have low bonding efficiency, require multiple positioning and bonding processes, and have a large demand for tooling. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tooling for bonding sheet metal parts to panels, which can simultaneously bond sheet metal parts of different thicknesses to one side of the panel, thereby improving bonding efficiency.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a tooling for bonding sheet metal parts to panels, characterized in that it includes:

[0007] A base is provided with a first support member for supporting a first sheet metal part to be bonded and a second support member for supporting a second sheet metal part to be bonded, with the support surface of the first support member at a lower height than the support surface of the second support member. Simultaneously, the base is also provided with a third support member for supporting a panel to be bonded, with the support surface of the third support member at a higher height than the support surface of the second support member. The third support member is an elastic member and can move downwards under external force, allowing the lower surface of the panel to be bonded, supported on the third support member, to be bonded to the upper surface of the second sheet metal part to be bonded, supported on the second support member.

[0008] A lifting mechanism is located below the first support member and is used to drive the first support member to move upward, so that the upper surface of the first sheet metal part to be bonded, which is supported on the first support member, can be bonded to the lower surface of the panel to be bonded, which is supported on the third support member.

[0009] Therefore, before the bonding operation, the second metal sheet with a smaller thickness can be placed on the second support, the first metal sheet with a larger thickness can be placed on the first support, and the panel to be bonded can be placed on the third support, and then when the panel to be bonded moves downward under the action of an external force, the lower surface of the panel to be bonded first contacts the upper surface of the second metal sheet to be bonded, so that the two are bonded, and then the first metal sheet to be bonded is moved upward by the jacking mechanism until it is bonded to the lower surface of the panel to be bonded, so that the first and second metal sheets with different thicknesses are both bonded to the lower surface of the panel, and the bonding efficiency is higher.

[0010] When the thicknesses of the first and second metal sheets are the same, the tooling device of the utility model can also be used for operation.

[0020] In the above scheme, in order to realize the positioning of the panel, preferably, a centering mechanism is further arranged on the base and used for acting on the edge of the panel to be bonded so that the panel to be bonded is placed centrally on the third support.

[0021] Preferably, the centering mechanism comprises:

[0022] A first slider is arranged on the lower surface of the base plate;

[0023] A first telescopic power element is arranged to drive the first slider to move in the horizontal direction, and the moving direction of the first slider is defined as the front-back direction.

[0024] A left connecting rod and a right connecting rod are arranged on the two sides of the first slider, the right end of the left connecting rod is rotatably connected to the first slider with the rotating axis extending upward and downward, and the left end of the right connecting rod is rotatably connected to the first slider with the rotating axis extending upward and downward.

[0025] A left slider and a right slider are arranged on the lower surface of the base plate and the two sides of the left and right connecting rods in a movable manner, the left end of the left slider is rotatably connected to the left connecting rod with the rotating axis extending upward and downward, and the right end of the right slider is rotatably connected to the right connecting rod with the rotating axis extending upward and downward.

[0027] Thus, the left and right positions of the panel to be bonded can be determined.

[0028] Further, the centering mechanism further comprises a fixed limiting block and a movable limiting block arranged on the two sides of each support element on the base plate to act on the front and back sides of the edge of the panel to be bonded, and the movable limiting block can move forward and backward under the driving of the second telescopic power element. Thus, the front and back positions of the bonded panel can be determined.

[0029] In the above-mentioned solutions, preferably, the second support element has two and is arranged on the two sides of the first support element.

[0030] Further, the third support element comprises at least three support nails arranged vertically and capable of being elastically telescoped upward and downward, each support nail is arranged on the periphery of the first support element, and the upper end of each support nail forms the support surface of the third support element.

[0031] Preferably, a pressing plate is further arranged above the third support element and can move downward under the action of the driving mechanism to act on the panel to be bonded on the third support element to provide the external force.

[0032] Compared with the prior art, the advantages of this utility model are as follows: Before the bonding operation, the thinner second sheet metal part to be bonded can be placed on the second support, the thicker first sheet metal part to be bonded can be placed on the first support, and the panel to be bonded can be placed on the third support. Then, when the panel to be bonded moves downward under the action of external force, its lower surface first contacts the upper surface of the second sheet metal part to be bonded to achieve bonding between the two. Then, the first sheet metal part to be bonded is moved upward by the lifting mechanism until it is bonded to the lower surface of the panel to be bonded, thereby achieving bonding of the first and second sheet metal parts with different thicknesses to the lower surface of the panel, and the bonding efficiency is high.

[0033] Furthermore, when the thickness of the first and second sheet metal parts is the same, the tooling of this utility model can also be used for operation. Attached Figure Description
