Description

Technical Field

[0001] The invention relates to workpiece gluing, and in particular to a workpiece gluing device and method for automatic gluing. Background Art

[0002] It is known that in the production process of general objects, there is often a gluing operation on the objects to facilitate the subsequent bonding of other components to the objects. Generally speaking, the gluing operation is to apply glue on the surface of the object by manually holding a brush or cloth impregnated with glue. However, the existing manual coating method is not easy to accurately control the amount and position of the glue. When the coating amount is insufficient, it is easy to cause the bonding strength between the object and other components to be insufficient and easy to separate. When the coating amount is too much or the coating position is inaccurate, the excess glue is easy to overflow when the object is pressed and bonded with other components, which not only affects the overall appearance of the object, but also requires additional work to remove the overflow glue, resulting in an increase in the overall manufacturing cost. Furthermore, most glues contain toxic chemicals that are easily volatilized. If the gluing operation is not done carefully, it is easy to cause harm to the health of the operator.

[0003] In order to solve the above problems, some relevant industries have tried to replace manual operations with automatic glue spraying. However, when spraying glue on the surface of an object, in order to completely cover the surface of the object with glue, the spraying area needs to be slightly larger than the surface area of ​​the object. Therefore, there is still a problem of glue residue on the outer periphery of the object or on the surface of the support platform that supports the object. Furthermore, when spraying glue, there are various restrictions on the thickness or type of glue used. For example, when the glue is too thick, the glue is easy to adhere to the nozzle and cause the nozzle to be blocked. Or oily glue is usually easy to volatilize and is not suitable for spraying on objects. In summary, the existing gluing equipment and methods still need to be improved. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a workpiece gluing device and method, which can improve production efficiency and product quality.

[0041] In order to more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Figure 1 As shown, a workpiece gluing device 1 according to a preferred embodiment of the present invention comprises a carrier 10, a shape information unit 20, a gluing unit 30, a driving unit 40, a control unit 50 and a glue delivery pipeline 60. In this embodiment, the workpiece S is described by taking a footwear component as an example, and the footwear component may be a sole, a midsole, a shoe upper or other components. In other embodiments, the workpiece S may be an object having elasticity, flexibility or made of plastic material.

[0042] The carrier 10 is used to transport the workpiece S. The carrier 10 can be used to place the workpiece S and transfer the workpiece S to multiple different processing areas. In this embodiment, the carrier 10 transports the workpiece S from a first processing area Z1 to a second processing area Z2, and then transports the workpiece S from the second processing area Z2 to a third processing area Z3. Based on the operation process of a production line, the workpiece gluing equipment 1 can perform gluing operations on multiple workpieces S in sequence, and each workpiece S can be an object with different appearances and sizes. In this embodiment, the carrier 10 is illustrated by taking a conveyor belt as an example. In practice, the carrier 10 can also be a carrier table. The carrier table can be provided with a clamp or a vacuum device to fix the workpiece on the carrying surface of the carrier table.

[0043] The shape information unit 20 is disposed in the first processing operation area Z1, and the control unit 50 is signal-connected with the shape information unit 20 and the driving unit 40. When the workpiece S is transported to the first processing operation area Z1 by the carrier 10, the shape information unit 20 captures the shape of the workpiece S and outputs a shape information to the control unit 50. In this example, the shape information unit 20 is illustrated by a three-dimensional photographic device, such as a depth camera, and the image captured by the depth camera has the three-dimensional morphology of the surface of the workpiece S. In practice, the workpiece shape capture unit 20 can be an image capture device, and the shape information can be an image signal. The workpiece shape capture unit 20 can also use other technical means, such as ultrasound, laser, or thermal imaging, to capture the three-dimensional surface information of the workpiece S.

[0044] The gluing unit 30 and the driving unit 40 are arranged in the second processing operation area Z2, the gluing unit 30 is used to apply glue to the surface of the workpiece S, and the driving unit 40 is used to drive the gluing unit 30 to move. Therefore, the control unit receives the shape information and controls the driving unit to drive the gluing unit to repeatedly perform a first action and a second action on a preset path according to the shape information to apply glue to the surface and make the surface covered with glue, wherein the first action includes the driving unit driving the gluing unit to approach the surface and contact the surface, and transfer the glue on the gluing unit 30 to the surface of the workpiece S in a contact transfer manner, and the second action includes the driving unit driving the gluing unit to detach from the surface. In practice, the driving unit 40 may also drive the carrier 10 to move relative to the gluing unit 30, and after receiving the shape information through the control unit 50 which is signal-connected to the carrier 10, the driving unit 40 is controlled according to the shape information to drive the carrier 10 to repeatedly perform a first action and a second action on a preset path to apply glue to the surface and make the surface covered with glue, wherein the first action includes the driving unit driving the carrier to approach the gluing unit so that the surface of the workpiece contacts the gluing unit, and the second action includes the driving unit driving the carrier away from the gluing unit so that the surface of the workpiece is separated from the gluing unit.

[0045] Please cooperate Figure 2 The gluing unit 30 includes a main body 302 and a gluing member 304. The main body 302 is combined with the driving unit 40. The gluing member 304 is used to absorb glue. The gluing member 304 is detachably combined with the main body 302 to facilitate the user to replace or clean the gluing member 304. In this embodiment, the gluing member 304 has a coating layer on its periphery. The coating layer is used to absorb glue. When the first action is performed, the coating layer is squeezed and compressed and pressed against the surface. When the second action is performed, the gluing member 304 is separated from the surface of the workpiece S and is not squeezed. The coating layer can be made of an elastic material to prevent the gluing unit 30 from scratching the surface of the workpiece S during the gluing process. The glue delivery pipeline 60 is arranged on the driving unit 40, one end of the glue delivery pipeline 60 is connected to a glue supply source, and the other end is for outputting glue to the glue coating member 304, so as to automatically provide the glue coating member 304 with a sufficient flow of glue, so that the glue can be evenly distributed on the surface of the workpiece S through the adhesion of the glue coating member 304.

[0046] The driving unit 40 includes a multi-axis robot arm, and the gluing unit 30 is disposed on the multi-axis robot arm. In this embodiment, a six-axis robot arm is used as an example, that is, the three axes of X, Y, and Z and the corresponding three rotation axes θ X ,θ Y ,θ Z Through the multi-axis robotic arm, the gluing unit 30 can be driven to perform surface gluing operations on the workpiece S from multiple different directions, so as to more accurately apply glue to the surface of the workpiece S, thereby improving the problem of inaccurate coating position of the existing gluing equipment. In other embodiments, the driving unit 40 can also be, for example, an X, Y, and Z three-axis driving component, and is not limited to the above-mentioned six-axis robotic arm. The shape information unit 20 can also be a one- and two-dimensional photographic device to obtain a two-dimensional image of the workpiece. Although the surface of the workpiece S has a high and low distribution, the glue coating member 304 has a compressible characteristic. Therefore, the design of the three-dimensional morphology of the high and low distribution of the surface of the workpiece S is covered by the compressible range of the glue coating member 304, and there is no need to rely on three-dimensional position parameters.

[0047] Through the above-mentioned structure, the workpiece gluing method of this embodiment can be performed. The workpiece gluing method of this embodiment can sequentially apply glue to workpieces of different shapes. Hereinafter, a three-dimensional workpiece is used as an example to illustrate. The workpiece gluing method includes: Figure 3 The steps shown, where:

[0048] Step S100 : The carrier 10 moves the workpiece S to a processing operation area. In this embodiment, the carrier 10 moves the workpiece S to the first processing operation area Z1 .

[0049] Step S102: The shape information unit 20 captures the image of the workpiece S located in the first processing area Z1 and outputs shape information. In this embodiment, the image captured by the depth camera has a three-dimensional morphology of the surface of the workpiece S, and the shape information includes three-dimensional position parameters of the surface of the workpiece S.

[0050] Step S104: The control unit 50 receives the shape information and controls the driving unit 40 according to the shape information. In other embodiments, the control unit 50 may also receive a two-dimensional image or a three-dimensional image of the workpiece and control the driving unit 40 according to the two-dimensional image or the three-dimensional image, so that the driving unit 40 drives the gluing unit 30 to move along the preset path.

[0051] Step S106: The driving unit 40 drives the gluing unit 30 to repeatedly perform the first action and the second action along the preset path R until the surface of the workpiece S is covered with glue, wherein when performing the first action, the gluing unit 30 contacts an area on the surface of the workpiece S, and the contact surface area between the gluing unit 30 and the surface of the workpiece S is smaller than the surface area of ​​the surface of the workpiece S. When performing the first action again, the area in contact with the surface of the workpiece S by the gluing unit 30 is adjacent to the area in contact with the surface of the workpiece S when the first action was performed last time, wherein the gluing unit 30 moves in a direction perpendicular to the surface of the workpiece S to a position in contact with the surface of the workpiece S. In other embodiments, the gluing unit 30 may also move in a direction not perpendicular to the surface of the workpiece S to contact with the surface of the workpiece S. In this embodiment, the carrier 10 moves the workpiece S from the first processing operation area Z1 to the second processing operation area Z2, wherein as Figure 4 As shown, the projection of the preset path R on a transverse reference plane S1 is a U-shaped path Ra, and the driving unit 40 drives the gluing unit 30 to move from a starting position P1 in the workpiece S to an end position P2 on the outer periphery of the workpiece S in a U-shaped manner along the preset path R, and repeats the first action and the second action during the movement until the surface is covered with glue, and the glue delivery pipeline 60 delivers glue to the glue-coated member 304 during the movement of the gluing unit 30 along the preset path R.

[0052] Please cooperate again Figure 4 , it is further explained that, in this embodiment, when the first action is performed again, the area Z1 where the gluing unit 30 contacts the surface of the workpiece S and the area Z0 where the gluing unit 30 contacts the surface of the workpiece S when the first action was performed last time are adjacent to each other and do not overlap. In this way, the time for completing the gluing of a single workpiece can be greatly reduced, thereby improving the productivity of the gluing operation. In practice, Figure 5 As shown, when the first action is performed again, the area where the gluing unit 30 contacts the surface of the workpiece S and the area where the gluing unit 30 contacts the surface of the workpiece S when the first action was last performed may also be arranged in a partially overlapping manner to achieve the effect of completely filling the surface of the workpiece S with glue.

[0053] Please cooperate Figure 6In this embodiment, the preset path R includes a plurality of first sections R1 and a plurality of second sections R2. The first section R1 is a section where the gluing unit 30 moves from a position above a region to be glued on the surface of the workpiece S to a point glue position P in contact with the region to be glued. The second section R2 is a section where the gluing unit 30 moves from the point glue position P to a position above another region to be glued. When performing the first action, the driving unit drives the gluing unit 30 to move to the point glue position P according to the first section R1. When performing the second action, the driving unit 40 drives the gluing unit 30 to move from the point glue position to a position above another region to be glued according to the second section R2, so as to effectively reduce the moving distance and improve the production efficiency. In this embodiment, the second section R2 is described by taking a straight line as an example. In other embodiments, the second section R2 may also be an arc or other shapes.

[0054] Please cooperate Figure 7 In other embodiments, the first section R1 may also be a section where the gluing unit 30 moves from a position above a region to be glued on the surface of the workpiece S to a gluing point position P in contact with the region to be glued, and the second section R2 is a section where the gluing unit 30 returns from the gluing point position P to a position above the region to be glued and then moves to a position above another region to be glued. When performing the first action, the driving unit 40 drives the gluing unit 30 to move to the gluing point position P along the first section R1. When performing the second action, the driving unit 40 drives the gluing unit 30 to return from the gluing point position P to a position above the region to be glued and then moves to a position above another region to be glued along the second section R2 to facilitate performing the first action again.

[0055] Please cooperate Figures 8 to 9 In this embodiment, when performing the first action, the gluing unit 30 is as follows Figure 8 As shown in FIG. 1 , the workpiece S is in contact with the surface of the workpiece S and as shown in FIG. Fig. 9 As shown, the surface of the workpiece S is pressed vertically downward for a distance so that the coating layer of the glue-coating member 304 is squeezed and compressed and pressed against the surface of the workpiece S. When the second action is performed, the gluing unit 30 is separated from the surface of the workpiece S, so the glue-coating member 304 is not squeezed. Therefore, the action of squeezing the coating layer of the glue-coating member 304 can release the adsorbed glue and make the glue effectively fill the pores or uneven recesses on the surface of the workpiece S, thereby effectively improving the bonding strength between the workpiece S and other components.

[0056] Step S108: The control unit 50 controls the driving unit 40 to drive the gluing unit 30 to leave the surface of the workpiece S, and the carrier 10 moves the workpiece S to another operation area and moves another workpiece to the processing operation area. In this embodiment, the control unit 50 controls the driving unit 40 to drive the gluing unit 30 to leave the surface of the workpiece S, and the carrier 10 moves the workpiece located in the second processing operation area Z2 to the third processing operation area Z3 and moves another workpiece to the first processing operation area Z1.

[0057] In other embodiments, step S106 may also be that the driving unit 40 drives the carrier 10 to repeatedly perform a first action and a second action along the preset path R until the surface of the workpiece S is covered with glue, wherein when performing the first action, the gluing unit 30 contacts an area on the surface of the workpiece S, and the contact surface area between the gluing unit 30 and the surface of the workpiece S is smaller than the surface area of ​​the surface of the workpiece S, and when the first action is performed again, the area in contact with the surface of the workpiece S is adjacent to the area in contact with the surface of the workpiece S when the first action was performed last time; and step S108 may also be that the control unit 50 controls the driving unit 40 to drive the carrier 10 away from the gluing unit 30, so that the gluing unit 30 leaves the surface of the workpiece S.

[0058] In summary, the workpiece gluing device of the present invention receives the shape information through the control unit and controls the driving unit according to the shape information to drive the gluing unit 30 to repeatedly perform a first action and a second action on a preset path to apply glue to the surface and make the surface covered with glue. Therefore, the glue can be accurately applied to the surface of the workpiece, thereby improving the problem of glue overflow caused by manual gluing or gluing by spraying. Compared with the existing spray gluing equipment, the workpiece gluing device of the present invention is less limited by the type of glue and will not have the problem of nozzle clogging. In addition, by applying glue by applying glue to the surface of the workpiece, the glue can be effectively filled into the pores or uneven holes on the surface of the workpiece, thereby effectively improving the bonding strength between the workpiece and other components.
