Description

Technical Field

[0001] The invention relates to mold processing, and in particular to a cloth covering device and a cloth covering method. Background Art

[0002] Plastic molds are relatively hard and rough, and are not suitable for direct use as finished products. They need further processing, such as wrapping a layer of cloth on the surface to make it soft and comfortable, especially for molds that need to fit closely, such as head-mounted devices. The usual way of patching is to manually put the cloth with hot melt adhesive or glue on the mold and heat it to fuse it, or put the cloth into a processing base (jig) of the corresponding shape, and then put it into the mold for heating and fusing. The former is less efficient and has a high defective rate of finished products. The latter requires the processing base to be ready before the cloth can be put into the processing base, which is not efficient in time utilization. At the same time, the cloth sinks due to its own gravity, and at this time the mold needs to be put into the cloth. The cloth is prone to wrinkles and is difficult to observe. Summary of the invention

[0003] The present invention aims to provide a cloth covering device which is convenient to operate and suitable for assembly line production.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cloth-covering equipment, comprising a bottom plate, a top plate fixed to the bottom plate through a vertical plate, a lower mold fixed above the bottom plate, a linear motion mechanism fixed above the top plate, a fixed plate arranged below the top plate and fixed to an actuator of the linear motion mechanism, and a hanging plate suspended from the fixed plate; a convex strip corresponding to the mold to be covered with cloth is arranged above the lower mold, guide rails perpendicular to the bottom plate are arranged on the inner sides of the two vertical plates, the hanging plate is U-shaped, and both sides are slidably connected to the guide rails, the U-shaped opening is located directly above the lower mold, and a latch is provided.

[0005] Preferably, the hanging plates are symmetrically arranged and slidably connected to the guide rails via a sliding block.

[0006] Preferably, the hanging plate is connected to the fixed plate via at least three connecting rods.

[0007] Preferably, the vertical plate is provided with a barometer and a start switch.

[0008] Preferably, the linear motion mechanism is a cylinder.

[0009] The present invention also provides another technical solution: a method for covering a cloth, comprising the following steps: S1, placing the mold with the cloth on it on the convex strip of any of the above-mentioned lower molds, observing and leveling it; S2, hanging the upper mold on the hanging plate; S3, starting the linear motion mechanism, and the actuator drives the fixed plate to move downward, thereby moving the upper mold downward, and after being pressed with the lower mold for a certain period of time, the actuator moves upward, driving the fixed plate and the upper mold to move upward; S4, remove the upper mold.

[0010] Preferably, one side of the upper mold is provided with an upper mold base plate, and the other side is provided with a groove corresponding to the cloth cover surface of the mold.

[0011] Preferably, the middle portion of the upper mold is hollow.

[0012] Preferably, the inner cavity width of the groove is greater than the opening width.

[0013] Preferably, the upper die is provided with a grabbing hole.

[0014] Compared with the prior art, the cloth-covering equipment provided by the present invention has changed positions of the upper mold and the lower mold, and correspondingly, the place where the mold is placed has also changed. The advantage brought about by this is that the mold with the cloth completed can be placed in advance, and at the same time, the cloth can be observed to see if there are any wrinkles, and timely adjustments can be made. When the upper mold is in place, it can be pressed, and the pressing process can be used to prepare the cloth covering of the next mold, saving time. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used in this specification and in the specification of the present invention are only used to describe specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0021] The cloth covering device provided by the present invention is as follows: Figure 1 As shown, it includes a bottom plate 1, a vertical plate 2, a top plate 3, a lower mold 4, a hanging plate 7, a fixing plate 6, and a linear motion mechanism 5. The top plate is fixed to the bottom plate by two vertical plates. The two vertical plates are respectively placed on both sides of the bottom plate. Reinforcement parts are provided at the connections with the bottom plate and the top plate to make the frame formed by the vertical plates, the bottom plate, and the top plate firm.

[0022] The lower mold is fixed above the bottom plate, and a convex strip 41 corresponding to the mold to be covered with cloth is arranged on the top. The mold is provided with a cloth covering surface on one side, and a groove corresponding to the convex strip is arranged on the other side. Preferably, the lower mold is provided with a lower mold base plate 43, and the bottom plate 1 is provided with a pad 42, which is fixed to the bottom plate. The lower mold base plate and the pad are detachably fixed, and the pad is provided with several mounting positions, so that different lower molds can be installed, which is suitable for molds of various specifications. The pad can be set at a certain height to prevent the hanging plate from colliding with the bottom plate.

[0023] The linear motion mechanism 5 is fixed above the top plate 3, and the fixed plate 6 is arranged below the top plate 3 and fixed to the actuator of the linear motion mechanism 5. Obviously, the linear motion mechanism passes through the top plate, and its main body is above the top plate, and the actuator is below the top plate. The actuator moves up and down, and the movement direction is perpendicular to the bottom plate. The hanging plate 7 is suspended from the fixed plate 6 and is connected to the fixed plate through at least three connecting rods 61. Preferably, it is connected to the fixed plate through four connecting rods. The connecting rod passes through the fixed plate and the hanging plate, and its length is greater than the sum of the thickness of the fixed plate and the hanging plate. Both end points are greater than the aperture of the fixed plate and the hanging plate, and at most one end is fixed to the fixed plate or the hanging plate, that is, at least one end is free to slide, ensuring that the fixed plate and the hanging plate are movable. Preferably, the upper end of the connecting rod is fixed to the fixed plate, and the lower end is slidably connected to the hanging plate.

[0024] The inner sides of the two vertical plates 2, i.e. the sides close to each other, are provided with guide rails 21 perpendicular to the bottom plate 1. The guide rails may be guide grooves or guide bars. The hanging plate 7 is arranged in a U shape, i.e. the front side of the hanging plate is opened, and the two sides without openings are slidably connected to the guide rails 21. Preferably, the hanging plates 7 are symmetrically arranged and slidably connected to the guide rails 21 through a slider. The U-shaped opening is located directly above the lower mold 4, and a clamping position is provided at the opening of the hanging plate.

[0025] Preferably, the vertical plate 2 is provided with a barometer 8 and a start switch 9 for detecting air pressure and starting the device.

[0026] Preferably, the linear motion mechanism 5 is a cylinder. In simple two-point linear motion, the advantages of a cylinder are more obvious.

[0027] The present invention also provides a method for covering a cloth, comprising the following steps: S1, placing the mold with the cloth laid on it on the convex strip of the lower mold as claimed in any one of claims 1 to 5, observing and leveling it; S2, hanging the upper mold 10 on the hanging plate; S3, starting the linear motion mechanism, and the actuator drives the fixed plate to move downward, thereby moving the upper mold downward, and after being pressed with the lower mold for a certain period of time, the actuator moves upward, driving the fixed plate and the upper mold to move upward; S4, remove the upper mold.

[0028] After the above steps, the mold has been covered and is in the groove of the upper mold. It can be taken out or remain in the upper mold to participate in the operation of the next station. The upper mold is a fixture on the assembly line and is suitable for the operation of multiple stations.

[0029] Preferably, an upper mold base plate 12 is provided on one side of the upper mold, and a groove 11 corresponding to the cloth surface of the mold is provided on the other side. Preferably, the inner cavity width of the groove is greater than the opening width. The upper mold base plate is provided with a hanging position corresponding to the clamping position, and the clamping position can be a U-shaped opening groove, and the corresponding hanging position provided on the upper mold base plate is a convex groove; or the clamping position is a plurality of corners of a polygon, and the upper mold base plate is a corresponding polygon; or the clamping position is a plurality of column positions, and the hanging position is a corresponding hole position; and so on, as long as the upper mold can maintain the horizontal and vertical position unchanged under the action of gravity. In this way, the upper mold moves downward, and moves downward under gravity at first. When it reaches the lower mold, it is pressed downward by the fixed plate, so as to be pressed together with the lower mold. After the pressing is completed, the fixed plate drives the hanging plate and thus drives the upper mold to move upward.

[0030] The upper die and the lower die both correspond to the mold, that is, the upper die and the lower die also correspond to each other, and when the two are combined, a cavity similar to the mold is formed.

[0031] In order to save materials, preferably, the middle part of the upper mold is hollow.

[0032] In order to facilitate automated operation, preferably, the upper die is provided with a grabbing hole 13 .

[0033] This technical solution is applicable to molds of different specifications and can realize assembly line operation. The upper mold is a fixture of uniform specifications corresponding to the current lower mold of the assembly line, that is, the upper mold is hung on the hanging plate. The upper mold here is not the same upper mold, but the next upper mold of the same specification on the assembly line.

[0034] It should be noted that the mutual combination of the above-mentioned technical features forms various embodiments, which should be regarded as the scope recorded in the specification of the present invention.

[0035] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
