[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] The attachment device provided in this embodiment includes a housing (not shown in the figure), a machine 1, a carrier 2, a transfer mechanism 3, a positioning mechanism 4 and a pressure-maintaining mechanism 5. Figures 1 to 7 The connection relationship and working principle of the aforementioned components are described in detail.

[0041] like Figure 1 As shown, Figure 1 A schematic diagram of an axonometric view of the attaching device is shown. Among them, the above-mentioned carrier 2, transfer mechanism 3, positioning mechanism 4 and pressure-maintaining mechanism 5 can all be arranged on the machine 1 and located in the shell, and the shell can be used to protect the above-mentioned components. Among them, one side of the shell is open, and this opening is used to take and place the product 100 to be sealed. This process will be explained in the subsequent description. The machine 1 is provided with an avoidance opening on the same side as the shell opening. The plate is set to retract partly into the cavity of the machine 1, and the bottom plate is shortened accordingly. It is convenient for workers to place their legs when sitting on one side of the machine 1 to load materials. That is, it can be understood that the retracted part of the plate on the front side of the machine 1 makes the front part of the machine 1 suspended to form an avoidance opening.

[0042] See also Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the structure of the carrier 2 and the transfer mechanism 3, Figure 3 Schematic diagram of the structure of the carrier 2 and the transplanter 3 without the carrier plate 22. Figure 2 As shown, in the embodiment, the carrier 2 is used to place the product 100 to be sealed (hereinafter referred to as the product, and the product in this embodiment can be a packaging box), and the transfer mechanism 3 is used to drive the carrier 2 to and from the loading station and the processing station (the position at the opening of the shell is the loading station, and the position below the pressure-maintaining mechanism 5 is the processing station). The positioning mechanism 4 needs to correct the position of the product 100. At the same time, in order to avoid wear on the bottom of the product 100 during the correction process, the carrier 2 moves with the product 100. Therefore, it can be understood that the movement of the carrier 2 relative to the transfer mechanism 3 ultimately realizes the movement of the product 100 relative to the transfer mechanism 3, and realizes the position correction of the product 100.

[0043] Based on the working principle described above, the following will be combined Figure 2 and Figure 3 Describe the specific structure of the carrier 2 and the transfer mechanism 3. The transfer mechanism 3 may include a transfer drive 31, a base plate 32 and a limit buffer structure 33. The base plate 32 is slidably connected to the machine platform 1 via a linear slide rail. The transfer drive 31 is fixed to the machine platform 1, and its driving end is connected to the base plate 32. It can be understood that the transfer drive 31 drives the base plate 32 to move along the second direction, and the limit buffer structure 33 limits and buffers the base plate 32. In this embodiment, the transfer drive 31 may include a cylinder, and the limit buffer structure 33 may include a hydraulic buffer. The hydraulic buffer may be respectively arranged at the front and rear ends of the moving direction of the base plate 32 to respectively limit the movement of the base plate 32 in the second direction. These are all prior arts and will not be described in detail herein. In this embodiment, Figure 1 The X direction is defined as the first direction, the Y direction is defined as the second direction, and the Z direction is defined as the third direction.

[0044] Furthermore, the carrier 2 may include a connecting plate 21, a carrier plate 22 and an L-shaped stopper 23. The connecting plate 21 is arranged on the bottom plate 32 along the second direction through two sets of linear slide rails, that is, the connecting plate 21 can slide on the bottom plate 32 along the second direction. It can be understood that the carrier 2 can drive the product 100 to slide along the second direction; the carrier plate 22 is arranged on the connecting plate 21 along the first direction through two sets of linear slide rails, then what can be achieved is that the carrier plate 22 can slide along the first direction. The above-mentioned setting method can ultimately achieve that the carrier plate 22 is relatively The bottom plate 32 can slide along the first direction and the second direction respectively, that is, the product 100 on the carrier plate 22 can also move in the first direction and the second direction along with the carrier plate 22. It can be understood that the product 100 is movable relative to the bottom plate 32 as a whole, because it is the movement of the carrier plate 22 that ultimately drives the movement of the product 100, and there is no direct movement between the product 100 and the carrier plate 22. Therefore, in the process of positioning the product 100, no friction is generated at the bottom of the product 100, thereby protecting the product 100 from wear due to positioning.

[0045] Furthermore, L-shaped blocks 23 are arranged at the four corners of the carrier plate 22, and the four L-shaped blocks 23 and the carrier plate 22 are arranged to form a profiling cavity, in which the product 100 can be placed, wherein any two adjacent L-shaped blocks 23 are lower than the other two L-shaped blocks 23 in the third direction, and a height difference is formed between the L-shaped blocks 23, so that the product 100 can be placed in the profiling cavity conveniently. Since the shapes of the profiling cavity and the product 100 are compatible, we can adapt to products of different sizes by changing the positions of the L-shaped blocks 23, which requires that the L-shaped blocks 23 and the carrier plate 22 are detachably connected, for example, they can be fixed by threads, and of course, the carrier 2 can also be customized according to different models of products 100.

[0046] Furthermore, if Figure 3As shown, the carrier 2 also includes a buffer structure, which includes two groups of buffer structures, which are respectively arranged between the bottom plate 32 and the connecting plate 21, and between the carrier plate 22 and the connecting plate 21. The specific structure is described by taking the buffer structure between the carrier plate 22 and the connecting plate 21 as an example: the buffer structure includes a guide rod 241, an end plate 242, a connecting block 243 and an elastic member 244. The end plate 242 is arranged on the connecting plate 21, and the two ends of the guide rod 241 are respectively connected to the end plate 242. Two connecting blocks 243 are sleeved on the rod body of the guide rod 241 between the end plates 242. The connecting blocks 243 can all slide along the guide rod 241, and the connecting blocks 243 are connected to the carrier plate 22. When the carrier plate 22 slides, the connecting blocks 243 can move accordingly. The guide rod 241 between the end plate 242 and the connecting block 243 is sleeved with an elastic member 244. When the carrier plate 22 is pushed along the extension direction of the guide rod 241, the carrier plate 22 moves to one side, and the elastic member 244 on the corresponding side is compressed. On the one hand, it can play a buffering role to prevent the product 100 from being damaged by the inertia collision on the mounting plate 4141 during the positioning process, and on the other hand, the carrier plate 22 can be reset when the positioning of the product 100 is released. In this embodiment, the elastic member 244 can be a spring.

[0047] See also Figures 4 to 6 , Figure 4 The schematic diagram of the structure of the positioning mechanism 4 and the pressure-maintaining mechanism 5 is shown. Figure 5 shows a partial structural schematic diagram of the positioning mechanism 4, Figure 6 FIG. 4 shows a schematic diagram of the structure of the positioning mechanism 4 when viewed from above. Figure 4 As shown, the positioning mechanism 4 may include a first positioning component 41 and a second positioning component 42. The first positioning component 41 is used to position the product 100 at a specified position, providing a positioning basis for the positioning work of the second positioning component 42 and facilitating the normal subsequent pressure maintenance work. The second positioning component 42 provides guidance for the attachment of the seal to avoid inaccurate alignment of the seal relative to the product 100.

[0048] Preferably, the first positioning assembly 41 may include a mounting frame 411, a movable plate 412, a movable plate driving member 413 and a positioning component 414. The mounting frame 411 may be mounted on the machine 1, and includes vertical plates on both sides and a horizontal plate connected to the ends of the two vertical plates. Vertical plates are provided on both sides of the vertical plates. The movable plate 412 is slidably connected to the vertical plates through linear bearings. One end of the movable plate driving member 413 is fixed to the horizontal plate, and the other end is connected to the movable plate 412, that is, the movable plate driving member 413 can drive the movable plate 412 to move along the third direction. The positioning component 414 is provided on the movable plate 412, and moves with the movement of the movable plate 412.

[0049] Specifically, the positioning member 414 includes a mounting plate 4141, a first pushing member and a second pushing member. The mounting plate 4141 is provided with four groups. The first pushing member and the second pushing member are respectively provided on the mounting plate 4141. The first pushing member realizes the positioning of the product 100 in the first direction, and the second pushing member realizes the positioning of the product 100 in the second direction. In this embodiment, for the convenience of description, we call the mounting plate 4141 close to the side of the shell opening a mounting front plate, the mounting plate 4141 opposite thereto a mounting rear plate, and the mounting plates 4141 on both sides are called mounting side plates.

[0050] The first pusher is disposed on one of the mounting side plates, and is used to push one side of the product 100 against the other mounting side plate. The first pusher includes a first driving member 4142 and a first push plate 4143. The first driving member 4142 is disposed on the mounting side plate, and the first push plate 4143 is connected to the driving end of the first driving member 4142. The first pushing member also includes a guide member 4144, which provides guidance for the movement of the first push plate 4143 and can increase the stability of the movement of the first driving member 4142 driving the first push plate 4143. In this embodiment, the first driving member 4142 can be a cylinder, and the guide member 4144 includes a guide column and a linear bearing, which are all prior arts.

[0051] The second pushing member is to realize the positioning of the product 100 in the second direction. In order to avoid the displacement of the product 100 during the positioning in the second direction, the first pushing member needs to keep the action of pressing against the product 100 during this process, and it needs to ensure that the product 100 is not damaged. In order to achieve the technical purpose mentioned above, the following settings are made: a sliding plate 4145 is provided on the first push plate 4143 and the mounting side plate where the first pushing member is not installed. The sliding plate 4145 and the first push plate 4143, and the sliding plate 4145 and the mounting side plate are respectively connected by linear slide rails, and a buffer assembly is provided between the sliding plate 4145 and the first push plate 4143, and between the sliding plate 4145 and the mounting side plate. The structure and principle of the buffer assembly here are the same as those of the buffer structure of the carrier 2 mentioned above, which will not be described in detail here.

[0052] The second pusher is arranged on the rear mounting plate, and includes a second driving member 4146, a second push plate 4147 and a guide member 4144. The fixed end of the second driving member 4146 is arranged on the rear mounting plate, the second push plate 4147 is connected to the rear mounting plate of the second driving member 4146, and the guide member 4144 provides guidance for the movement of the second push plate 4147 and increases the stability of the movement of the second push plate 4147 driven by the second driving member 4146. In this embodiment, the second driving member 4146 can be a cylinder, and the guide member 4144 includes a guide column and a linear bearing, which are prior art.

[0053] Preferably, rubber pads 4148 are respectively provided on the sliding plate 4145, the second push plate 4147 and the installation front plate to achieve flexible contact with the product 100 and avoid damage to the product 100 during the positioning process; an opening is respectively provided on one side where the installation front plate and the movable plate 412 are connected, so that the installation front plate and the movable plate 412 form a U-shaped plate respectively. After the first positioning component 41 completes the preliminary positioning of the product 100, the above-mentioned opening can expose the part of the product 100 to be attached, which is convenient for the attachment of the seal and the subsequent pressure maintenance, and avoids interference with the work of the second positioning component 42 and the pressure maintenance mechanism 5.

[0054] like Figure 6 As shown, the second positioning assembly 42 includes a positioning block 421 and a positioning block driver 422. The positioning block driver 422 is arranged on the side of the movable plate 412 away from the mounting plate 4141. The positioning block 421 is arranged at the driving end of the positioning block driver 422. The positioning block driver 422 can drive the positioning block 421 to move along the second direction and the third direction respectively. The positioning block 421 is an L-shaped plate, which can provide a guide for the seal during the attachment process, that is, the two adjacent sides of the seal are attached along the inner side of the positioning block 421, so as to ensure that the seal will not be crooked. Corresponding to the opening set on the movable plate 412 mentioned above, interference with the second positioning assembly 42 is avoided.

[0055] See also Figure 7 , Figure 7 FIG. 5 shows a schematic structural diagram of the pressure-maintaining mechanism 5. Figure 7 As shown, the pressure-maintaining mechanism 5 is arranged on the horizontal plate of the mounting frame 411, and may specifically include a mounting base 51, a first pressure-maintaining driving member 52, a second pressure-maintaining driving member 53, a lower pressure block 54 and a side pressure block 55. The first pressure-maintaining driving member 52 is arranged on the horizontal plate, and its driving end is connected to the mounting base 51. The first pressure-maintaining driving member 52 can simultaneously drive the second pressure-maintaining driving member 53, the lower pressure block 54 and the side pressure block 55 to slide in the third direction, and the second pressure-maintaining driving member 53 drives the side pressure block 55 to move in the second direction, thereby finally achieving pressure-maintaining of the seals on both sides attached to the product 100.

[0056] Preferably, the mounting base 51 may include two substrates and two connecting columns, the connecting columns connect the two substrates, a certain interval between the two substrates can form an installation space, the driving end of the first pressure-maintaining driving member 52 is connected to one of the substrates, and the second pressure-maintaining driving member 53 is arranged in the installation space formed by the two substrates. In an embodiment, the first pressure-maintaining driving member 52 and the second pressure-maintaining driving member 53 may respectively include a cylinder.

[0057] During pressure maintenance, the first pressure maintenance driving component 52 drives the mounting base 51 to be pressed downward until the lower pressure block 54 is against the upper side of the seal attached to the product 100. To ensure the stability of the pressing process, the pressure maintenance mechanism 5 may further include a guide component and a limit buffer component to ensure the stability of the pressing block 54 and to limit the pressing stroke to avoid excessive pressing stroke that may damage the product 100. Then the second pressure maintenance driving component 53 drives the side pressure block 55 to maintain pressure on the side of the seal.

[0058] The working steps of the attachment device are as follows:

[0059] First, the transfer mechanism 3 drives the carrier 2 to the opening of the shell, and the worker places the product 100 on the carrier 22 to complete the manual loading. Then the transfer mechanism 3 drives the carrier 2 carrying the product 100 to the mounting station. At this time, the movable plate 412 is pressed down until the movable plate 412 is close to pressing on the product (a certain distance is left between the two to avoid wear on the top of the product 100 during the positioning process). Then the first positioning component 41 applies a thrust to the product 100 to achieve positioning of the product in the first direction and the second direction. During the process, it is the movement of the carrier 22 that ultimately drives the product 100 to move. There is no direct movement between the product 100 and the carrier plate 22, so during the positioning of the product 100, no friction is generated on the bottom of the product 100, thereby protecting the product 100 from wear due to positioning; after completing the positioning of the product 100, the second positioning component further positions the product 100, and the two inner sides of the positioning block 421 are semi-enclosed outside the attachment area, and the two adjacent sides of the seal are pasted along the inner sides of the positioning block 421, so as to ensure that the seal will not be crooked, thereby assisting in the manual attachment of the seal; finally, the pressure-maintaining mechanism 5 maintains the pressure on the seal.
