DETAILED DESCRIPTION

[0026] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the utility model, and the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] Example:

[0029] like Figure 1-4 As shown, in this embodiment, a device for closing a cover of a special-shaped plastic housing is provided, comprising a pressing device and a flexible clamp device;

[0030] The pressing device has a pressing drive end that can move relative to the flexible clamp device;

[0031] The flexible clamp device includes a flexible clamp seat 1, a clamping drive component and a flexible support portion. The clamping drive component is arranged on the flexible clamp seat 1. A clamping area with adjustable size is formed between the driving end of the clamping drive component and the flexible clamp seat 1. The flexible support portion is arranged in the clamping area, and the flexible support portion includes a plurality of flexible support components.

[0032] This embodiment is used for closing a special-shaped plastic shell 25. When in use, firstly, by acting on the driving end position of the clamping drive component, the size space of the clamping area becomes larger, the special-shaped plastic shell 25 (i.e., the workpiece) is placed at the flexible support portion, and then the pressing drive end of the pressing device is brought into contact with the special-shaped plastic shell 25. At this time, the flexible support component produces elastic deformation displacement under the action of external force (i.e., the force of the pressing drive end of the pressing device), forming a support surface that fits the special-shaped plastic shell 25 tightly. At this time, the driving end position of the clamping drive component is then acted on to reduce the size space of the clamping area, and the spacing between adjacent flexible support components becomes smaller and fits each other. At this time, the friction between the flexible support components increases, and the flexible support portion is in a locked state, and the flexible support portion no longer produces elastic deformation displacement with the external force. The above can complete the adjustment of the support surface of the special-shaped plastic shell 25, so as to put into continuous closing production work. If a plastic shell of different specifications is replaced, it can be adjusted again according to the above operation. The purpose of this application is to improve the many shortcomings of the traditional clamping method, such as the difficulty in positioning the special-shaped plastic shell 25 and the need for frequent replacement of tooling fixtures, and the high labor intensity and susceptibility to hand diseases caused by manual closing of the cover. The structure of this application can solve the current situation of inaccurate clamping and positioning of the special-shaped plastic shell 25, troublesome adjustment, poor closing quality, and high labor intensity, and achieve the advantages of rapid clamping and positioning, simple operation, quality assurance, and high production efficiency.

[0033] In this embodiment, the specific structure of the flexible clamp device is as follows:

[0034] The flexible clamp seat 1 has a cavity, the clamping drive assembly is arranged on the side of the flexible clamp seat 1, the driving end of the clamping drive assembly is in the cavity, and the driving end of the clamping drive assembly and the cavity form a clamping area.

[0035] Specifically, the clamping drive assembly includes a handle member 2, a driving screw 3 and a clamping block 4. The driving screw 3 is rotationally matched with the side of the flexible clamp seat 1. One end of the driving screw 3 is threadedly matched with the clamping block 4, and the other end is connected to the handle member 2. The clamping block 4 is slidingly matched with the inner wall surface of the cavity of the flexible clamp seat 1. The clamping block 4 is the driving end of the clamping drive assembly.

[0036] Specifically, the flexible support assembly includes a support seat 5, an elastic member 6 and a support column 7. The elastic member 6 connects the support seat 5 and the support column 7 respectively. The support seat 5 is fixed to the bottom surface of the cavity of the flexible clamp seat 1, and the clamping block 4 is arranged corresponding to the position of the support column 7.

[0037] Specifically, the flexible support components are evenly distributed in the cavity of the flexible clamp seat 1 in a matrix.

[0038] Specifically, a clean air inlet 8 communicating with the cavity is provided on the side of the flexible clamp seat 1 .

[0039] In the above structure, the handle 2 causes the driving screw 3 to rotate relative to the flexible clamp seat 1, thereby causing the clamping block 4 to slide in the cavity of the flexible clamp seat 1, thereby achieving the size adjustment of the clamping area.

[0040] At the same time, the diameter of the support column 7 of this embodiment is 6 mm, the top of the support column 7 is a hemispherical structure, and the elastic member 6 can be a spring member. Because the clamping block 4 is arranged corresponding to the position of the support column 7, when the size space of the clamping area becomes smaller, the clamping block 4 acts on the support column 7, so that the spacing between the support columns 7 arranged in a matrix becomes closer, and the friction between the support columns 7 becomes larger, forming a locked state.

[0041] In this embodiment, the specific structure of the pressing device is as follows:

[0042] The pressing device includes a base 9, a bracket 10, a first cylinder part 11, a second cylinder part 12, a pressing head assembly and a slide 13. The first cylinder part 11 is connected to the base 9 through the bracket 10, the pressing head assembly is connected to the driving end of the first cylinder part 11, the pressing head assembly is the pressing driving end of the pressing device, the second cylinder part 12 is arranged on the base 9, the slide 13 is slidably matched with the base 9, the driving end of the second cylinder part 12 is connected to the slide 13, the slide 13 is arranged below the pressing head assembly, and the flexible clamp device is arranged on the slide 13.

[0043] Specifically, a guide rail seat 14 is provided on the base 9, and a guide rail member 15 is provided at the bottom of the slide 13, and the guide rail member 15 is slidably matched with the guide rail seat 14. The pressure head assembly includes a pressure head connecting plate 16 and a pressure head block 17, and the pressure head block 17 is fixed to the pressure head connecting plate 16, and the pressure head connecting plate 16 is connected to the driving end of the first cylinder member 11.

[0044] Specifically, the base 9 is further provided with a limit seat 18 and a buffer pad 19. The limit seat 18 is provided in the extension direction of the guide rail member 15, and the buffer pad 19 is provided on the limit seat 18. When the slide 13 contacts the buffer pad 19, the slide 13 is directly below the pressing drive end of the pressing device. The limit seat 18 and the buffer pad 19 limit the travel of the slide 13, and the buffer pad 19 has a buffering effect to protect the overall structure.

[0045] Specifically, it also includes an air source dual-connector 20 , a solenoid valve 21 , a travel switch 22 , a delay switch 23 and a foot switch 24 .

[0046] The working principle of the pressing device is as follows:

[0047] The air source two-piece 20 is connected to the air source and is connected to the first cylinder part 11 and the second cylinder part 12. The solenoid valve 21, the travel switch 22, the delay switch 23 and the foot switch 24 are powered on. In the initial state, the driving end of the second cylinder part 12 is in an extended state. At this time, the slide 13 is in an extended state. The staff performs the assembly process of the special-shaped plastic shell 25 on the flexible clamp seat 1 of the slide 13. After the upper and lower covers of the special-shaped plastic shell 25 are closed, the operator steps on the foot switch 24, and the second cylinder part 12 drives the flexible clamp seat 1 to retract, triggering the travel switch 22 to make the driving end of the first cylinder part 11 drive the pressure head assembly to move downward, and the upper cover and the lower cover of the special-shaped plastic shell 25 are tightly pressed together. When the delay switch 23 sets the time (about 0.5s-1s), the driving end of the first cylinder 11 rises to the top position, the foot switch 24 is released, and the second cylinder 12 extends the flexible clamp seat 1 to remove the pressed special-shaped plastic shell 25. The next special-shaped plastic shell 25 is placed, and continuous production can be carried out according to the above steps.

[0048] In summary, the device for closing the lid of a special-shaped plastic shell of the present application has a reasonable structural design, good fit to the contour of a plastic shell with a complex shape, and good closing effect. It solves the shortcomings of the traditional device, which is difficult to position, easy to move, poor closing effect, and the need to repeatedly adjust the fixture. The flexible clamp device of the present application is driven by a cylinder structure to achieve the positional separation of the assembly process and the closing process, greatly ensuring the safety of the operator. The mechanical closing of the lid with a cylinder structure replaces the manual closing, which is efficient and labor-saving, and reduces the risk of occupational diseases for the operator.

[0049] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
