Description
Technical Field
[0001] The utility model relates to the technical field of glass processing, in particular to an inkjet base film pasting fixture. Background Technique
[0002] To meet the appearance requirements of users for the glass back covers of electronic products, it is often necessary to set multi-color decorative film layers on the glass surface so as to form a preset pattern on the glass back cover. When setting the multi-color decorative film layer on the glass back cover, the glass sheet is mainly installed on an inkjet base, and the pattern printing and superposition are carried out on the glass on the inkjet base through an inkjet printing system to complete the processing of the multi-color decorative film layer on the surface of the glass product. In order to avoid ink splashing onto the inkjet base, it is necessary to paste a film on the inkjet base in advance, and then load the glass on the inkjet base after pasting the film to prevent the ink from sticking to the inkjet base, thereby contaminating the glass installed subsequently, so as to ensure the inkjet effect of the product.
[0003] At present, in the industry, the film is mainly pasted on the inkjet base manually. Specifically, two employees stretch the film, then align the vent holes on the film with the product placement position on the inkjet base, and then cover the film down on the surface of the inkjet base. Finally, the film is stretched downward around to press the four sides of the film on the adhesive tape of the inkjet base, thus completing the film pasting. The above film pasting method requires the cooperation of two employees each time, with low film pasting efficiency and high labor cost; when stretching the film manually, it is difficult to control the stretching force, which will cause the film to be sometimes tight and sometimes loose. If the film is too loose, the film attached to the inkjet base will wrinkle, and if it is too tight, it will increase the difficulty of placing the product, and the product is easy to pop out, resulting in insufficient film pasting effect, thus affecting the product installation effect and the inkjet effect; in addition, each time the film is stretched, it is difficult for each person to maintain the same grasping position, which will cause some vent holes not to be aligned with the product placement position, thereby affecting the effect of placing the product, reducing the stability of product installation, and further interfering with the normal progress of the inkjet operation.

[0028] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0029] Please refer to Figure 1-3 and Figure 6-8, the present utility model discloses an inkjet base film pasting fixture 10 with high film pasting efficiency, good film pasting effect, stable product placement and low labor cost. The inkjet base film pasting fixture 10 includes a handheld movable pressing plate 100 and a film pasting main body 200. Among them, the film pasting main body 200 is used to receive the inkjet base 20 and the film material 30 and provide a film pasting operation position. The handheld movable pressing plate 100 is used to cooperate with the film pasting main body 200 to attach the film material 30 to the surface of the inkjet base 20. Specifically, the handheld movable pressing plate 100 includes a first pressing plate 110, a second pressing plate 120 located above the first pressing plate 110 and fixedly connected to the first pressing plate 110, and a third pressing plate 130. A first through hole 111 penetrating the upper and lower surfaces of the first pressing plate 110 is formed in the middle of the first pressing plate 110. The third pressing plate 130 is received in the first through hole 111 and elastically connected to the second pressing plate 120. The first pressing plate 110 and the third pressing plate 130 are used to jointly press the film material 30 against the upper surface and the side surface of the inkjet base 20. The film pasting main body 200 includes a fixed bottom plate 210, a cylinder fixing plate 220 located above the fixed bottom plate 210 and fixedly connected to the fixed bottom plate 210, a film placing movable plate 230 for receiving the film material 30 and supporting the first pressing plate 110, a positioning placing plate 240 for receiving the inkjet base 20 to be pasted with film, a downward pressing height limiting block 250 installed on the fixed bottom plate 210 and used to limit the downward pressing height of the film placing movable plate 230, and a pushing mechanism 260 installed on the fixed bottom plate 210. The thickness of the film placing movable plate 230 and the height of the positioning placing plate 240 need to meet the requirement that when the inkjet base 20 is placed on the positioning placing plate 240, the upper surface of the inkjet base 20 is lower than the upper surface of the film placing movable plate 230, or the upper surface of the inkjet base 20 is flush with the upper surface of the film placing movable plate 230. A second through hole 221 penetrating the upper and lower surfaces of the cylinder fixing plate 220 is formed in the middle of the cylinder fixing plate 220. The film placing movable plate 230 is received in the second through hole 221 and elastically connected to the fixed bottom plate 210; a third through hole 231 penetrating the upper and lower surfaces of the film placing movable plate 230 is formed in the middle of the film placing movable plate 230. The positioning placing plate 240 is fixed on the fixed bottom plate 210 and corresponds to the third through hole 231. A discharging operation port 241 penetrating the upper and lower surfaces of the positioning placing plate 240 is formed in the middle of the positioning placing plate 240. A pushing block 242 connected to the pushing mechanism 260 and lifting under the drive of the pushing mechanism 260 to push the inkjet base 20 is provided in the discharging operation port 241; A plurality of slide cylinder 270 are arranged along an annular path on the upper surface of the cylinder fixing plate 220 at the edge of the second through hole 221. A pushing block 271 for abutting against the side surface of the inkjet base 20 to make the film material 30 fit the side surface of the inkjet base 20 is fixed to the movable end of the slide cylinder 270.By setting the slide cylinder 270 as the power source for attaching the film material 30 to the side wall of the inkjet base 20, it can be ensured that each time after the film is pressed by the first pressure plate 110 and the third pressure plate 130, the pressing force of the push block 271 on the side wall of the inkjet base 20 and the film material 30 is consistent, thereby ensuring the stability of the film material 30 attached to the side of the inkjet base 20.
[0030] Please further combine Figure 3-10 During the film laminating operation, the inkjet base 20 is first mounted on the positioning plate 240, and then the film material 30 is covered on the film placing movable plate 230. At this time, the film material 30 is located above the inkjet base 20. The handheld movable pressing plate 100 is grasped, and the first pressing plate 110 of the handheld movable pressing plate 100 is placed on the film placing movable plate 230, and the second pressing plate 120 is pressed downward. At this time, the first pressing plate 110 and the third pressing plate 130 simultaneously press the film material 30, and the third pressing plate 130 is also pressed on the inkjet base 20. Since the positioning plate 240 is fixed on the fixed bottom plate 210, the inkjet base 20 is immobile, and the film placing movable plate 230 is pressed down by the first pressing plate 110 during the pressing process of the second pressing plate 120, thereby ensuring that the area on the film material 30 corresponding to the upper surface of the inkjet base 20 will not be deformed, and the portion of the film material 30 corresponding to the edge of the upper surface of the inkjet base 20 is bent (or stretched) under the joint action of the first pressing plate 110 and the side of the inkjet base 20, and corresponds to the side of the inkjet base 20. When the film placing movable plate 230 is pressed down to abut against the pressing height limit block 250, the slide cylinder 270 works and drives the push block 271 to move in the direction close to the inkjet base 20, thereby pushing the bent film material 30 to the side of the inkjet base 20, so that the film material 30 fits the side of the inkjet base 20. Then, the hand-held movable pressing plate 100 is lifted, and the slide cylinder 270 drives the push block 271 to retract and leave the film material 30. At this time, by actuating the push mechanism 260, the push block 242 can be raised and the inkjet base 20 can be lifted from the positioning plate 240, so as to take out the inkjet base 20 after film pasting. At this point, a film pasting operation of the inkjet base 20 is completed.
[0031] For the above-mentioned inkjet base film pasting fixture 10, during film pasting, place the inkjet base 20 on the positioning placement plate 240, place the film material 30 on the film placing movable plate 230, press the handheld movable pressing plate 100 on the film placing movable plate 230, and press down the second pressing plate 120. Through the combined action of the third pressing plate 130 and the sliding table cylinder 270, the film material 30 can be attached to the upper surface and side surface of the inkjet base 20, that is, the film pasting of the inkjet base 20 is realized. After film pasting, push the pushing block 242 through the pushing mechanism 260 to take out the inkjet base 20 after film pasting. It only requires one person to complete the film pasting operation of the inkjet base 20, improving the film pasting efficiency and reducing the labor cost during operation; the film material 30 is pressed tightly against the side surface of the inkjet base 20 by the pushing block 271 on the sliding table cylinder 270, ensuring that the pressing force is the same each time when the surrounding film material 30 is pasted on the inkjet base 20; by setting the downward pressing height limiting block 250, it is ensured that the stretching amount of the film is the same each time, avoiding the influence on the product placement caused by too large or too small film tension; the third pressing plate 130 and the sliding table cylinder 270 act together to realize the two-stage pressing die for the inkjet base 20, which can effectively ensure that the pressing position of the film is basically the same each time and the stretched area is the same each time, avoiding the situation of uneven stretching and improving the film pasting effect of the inkjet base 20.
[0032] Specifically, please combine Figure 1-2 and Figure 6, the handheld movable pressing plate 100 further includes a plurality of first support columns 140 located between the first pressing plate 110 and the second pressing plate 120 and fixedly connected to the first pressing plate 110 and the second pressing plate 120 respectively, a plurality of first guide shafts 150 fixedly connected to the upper surface of the third pressing plate 130 and slidably passing through the second pressing plate 120, a plurality of first fixed stoppers 151 fixedly arranged at the tops of the respective first guide shafts 150 and capable of abutting against the upper surface of the second pressing plate 120, and a plurality of first return springs 152 sleeved on the respective first guide shafts 150 and abutting against the second pressing plate 120 and the third pressing plate 130 respectively. The first support columns 140 are used to connect the first pressing plate 110 and the second pressing plate 120. The first guide shafts 150 are used to define the extension and compression directions of the first return springs 152, preventing the first return springs 152 from shaking, so as to improve the smoothness of the lifting of the third pressing plate 130 relative to the first pressing plate 110. The first fixed stoppers 151 are used to define the rebound positions of the first return springs 152 and prevent the first guide shafts 150 and the first return springs 152 from falling off the second pressing plate 120. The first return springs 152 are used to provide the power for the reset of the third pressing plate 130 after the handheld movable pressing plate 100 leaves the film attaching main body 200. Specifically, when the handheld movable pressing plate 100 leaves the film attaching main body 200, the restraint force on the third pressing plate 130 is released, and the first return springs 152 will recover their deformation and drive the third pressing plate 130 to move towards the direction close to the lower surface of the first pressing plate 110, thereby completing the reset of the third pressing plate 130. Further, in this embodiment, the third pressing plate 130 has an annular structure, and a gripping handle 160 is fixedly arranged on the upper surface of the second pressing plate 120. By providing the gripping handle 160, a gripping portion of the handheld movable pressing plate 100 is provided, so as to reduce the difficulty of moving and gripping the handheld movable pressing plate 100.
[0033] Please refer to Figure 1-3 and Figure 6, the film applying main body 200 further includes a plurality of second support columns 280 located between the fixed bottom plate 210 and the cylinder fixing plate 220 and fixedly connected to the fixed bottom plate 210 and the cylinder fixing plate 220 respectively, a plurality of second guide shafts 290 fixedly connected to the upper surface of the fixed bottom plate 210 and slidably passing through the film releasing movable plate 230, a plurality of second fixing stoppers 291 fixedly arranged at the tops of the respective second guide shafts 290 and capable of abutting against the upper surface of the film releasing movable plate 230, and a plurality of second return springs 292 sleeved on the respective second guide shafts 290 and abutting against the film releasing movable plate 230 and the fixed bottom plate 210 respectively. Preferably, the second return spring 292 is a rectangular spring. In this embodiment, the second support columns 280 are used to connect the fixed bottom plate 210 and the cylinder fixing plate 220; the second guide shafts 290 are used to define the elongation and compression directions of the second return spring 292, avoiding the shaking of the second return spring 292 to improve the smoothness of the lifting of the film releasing movable plate 230 relative to the fixed bottom plate 210; the second fixing stoppers 291 are used to define the rebound position of the second return spring 292 and can prevent the second guide shafts 290 and the second return spring 292 from falling off the film releasing movable plate 230; the second return spring 292 is used to provide power for the reset of the film releasing movable plate 230 when the hand-held movable pressing plate 100 is removed from the film applying main body 200. Thus, through the reset rebound of the second return spring 292, it can be ensured that after each film pressing, the film releasing movable plate 230 can rebound to the initial position, making the film releasing position the same each time. Further, in this embodiment, a plurality of linear bearings 232 are fixedly arranged at intervals on the edge of the third through hole 231 on the film releasing movable plate 230, and a plurality of bearing guide shafts 233 corresponding to and passing through the respective linear bearings 232 and slidably cooperating with the linear bearings 232 are fixedly arranged on the upper surface of the fixed bottom plate 210. By arranging the linear bearings 232 on the film releasing movable plate 230 and installing the bearing guide shafts 233 on the fixed bottom plate 210, the guiding of the lifting action of the film releasing movable plate 230 is realized, further improving the smoothness of the lifting of the film releasing movable plate 230. In this embodiment, by arranging the second guide shafts 290 and the bearing guide shafts 233, the smoothness of the lifting of the film releasing movable plate 230 is ensured, so that when the inkjet base applies the film, the forces on all sides of its side are uniform, improving the film applying effect.
[0034] Please refer to Figure 1-3 and Figure 6-8, at least one positioning shaft 234 is provided on the film placing movable plate 230 at the edge of the third through hole 231, and at least one positioning hole 112 for correspondingly sleeving on the positioning shaft 234 is formed on the first pressing plate 110. Preferably, two positioning shafts 234 are symmetrically arranged at the center of the film placing movable plate 230. Correspondingly, two positioning holes 112 corresponding to each positioning shaft 234 are formed on the first pressing plate 110. In this way, during each film pasting, the positioning hole 112 on the first pressing plate 110 of the hand-held movable pressing plate 100 is correspondingly inserted through the positioning shaft 234 on the film placing movable plate 230, and then the second pressing plate 120 can be pressed down, ensuring that the position of the hand-held movable pressing plate is the same each time, realizing the rapid positioning of the hand-held movable pressing plate 100 and the film pasting main body 200, and reducing the operation difficulty of the film pasting operation of the inkjet base 20.
[0035] Furthermore, in this embodiment, a film material positioning mark 235 is provided on the film placing movable plate 230. In this way, when placing the film, the film material 30 can be placed on the film placing movable plate 230 according to the film material positioning mark 235 to ensure that the position of each film placement remains consistent. In addition, in this embodiment, a plurality of positioning blocks 243 are spacedly arranged on the positioning placement plate 240. The positioning blocks 243 are used for concave-convex cooperation with the grooves at the bottom of the inkjet base 20. In this way, after the inkjet base 20 is placed on the positioning placement plate 240, the inkjet base 20 can be limited by the mutual restraint between the positioning blocks 243 and the grooves to prevent the inkjet base 20 from shifting during the film pasting process.
[0036] The pushing mechanism 260 is used to provide the power for taking out the inkjet base 20 after film pasting. In this way, after the inkjet base 20 is pushed out by the pushing mechanism 260, the inkjet base 20 can be taken out by grasping the side or bottom surface of the inkjet base 20, avoiding the problem of inkjet base 20 pollution caused by manual contact with the film material 30. It should be noted that there are various alternative deformation mechanisms for the pushing mechanism 260 of this solution. Specifically, in one embodiment, the pushing mechanism 260 is an electric push rod or a pneumatic push rod. In another embodiment, the pushing mechanism 260 is a linear motor. In yet another embodiment, the pushing mechanism 260 is a connection structure of a driving motor and a screw nut, that is, the screw is fixed on the output shaft of the driving motor and extends in the vertical direction, the nut is rotatably sleeved on the screw, and the pushing block 242 is fixedly connected to the nut. In this way, during the process of the driving motor driving the screw to rotate, the nut will move along the axial direction of the screw, so that the pushing block 242 rises and falls in the unloading operation port 241 to push out the inkjet base 20.
[0037] In this embodiment, the pushing mechanism 260 includes a mounting block 261 fixed on the fixed bottom plate 210, a rotating shaft 262 rotatably passing through the mounting block 261, an L-shaped pressing rod 263 fixedly connected to the rotating shaft 262 and extending in a direction perpendicular to the axis of the rotating shaft 262, a spherical plain bearing 264 located below the unloading operation port 241 and hinge-connected to one end of the L-shaped pressing rod 263, and a guiding and fixing block 265 fixed on the lower surface of the positioning and placing plate 240 and corresponding to the unloading operation port 241. The spherical plain bearing 264 slidably passes through the guiding and fixing block 265 and is fixedly connected to the pushing block 242. The other end of the L-shaped pressing rod 263 is elastically connected to the cylinder fixing plate 220. In this way, the whole pushing mechanism 260 forms a lever mechanism. After the inkjet base 20 is pasted with a film, the end of the L-shaped pressing rod 263 far from the spherical plain bearing 264 can be pressed down, and the spherical plain bearing 264 will immediately lift upward. Due to the guiding and constraining effect of the guiding and fixing block 265 on the spherical plain bearing 264, the spherical plain bearing 264 can only move in the vertical direction, thereby pushing the pushing block 242 upward, so that the upper surface of the pushing block 242 extends out from the top opening of the unloading operation port 241 and pushes the inkjet base 20 to lift. In this way, the upper surface of the inkjet base 20 protrudes from the top opening edge of the third through hole 231, so as to remove the inkjet base 20 from the positioning and placing plate 240 in the third through hole 231. Further, the other end of the L-shaped pressing rod 263 is elastically connected to the cylinder fixing plate 220 through a tension spring 266. In this way, during the process of pressing down the L-shaped pressing rod 263, the tension spring 266 elongates; when the inkjet base 20 is removed and the L-shaped pressing rod 263 is released, the L-shaped pressing rod 263 will reset under the drive of the tension spring 266, so that the spherical plain bearing 264 drives the pushing block 242 to descend, so as to provide conditions for the placement of the inkjet base 20 during the next film pasting operation and avoid interference between the pushing block 242 and the inkjet base 20. It should be noted that in this embodiment, the size of the spherical plain bearing 264 needs to meet the requirement that when no force is applied to the L-shaped pressing rod 263, the upper surface of the pushing block 242 is lower than the upper surface of the positioning and placing plate 240, or the upper surface of the pushing block 242 is flush with the upper surface of the positioning and placing plate 240, so as to smoothly place the inkjet base 20 on the positioning and placing plate 240 before film pasting. In addition, in this embodiment, a deep groove ball bearing 267 is provided at the rotating connection part between the rotating shaft 262 and the mounting block 261. By providing the deep groove ball bearing 267, the friction force when the rotating shaft 262 rotates relative to the mounting block 261 can be reduced, and the pressing difficulty of the L-shaped pressing rod 263 can be lowered.
[0038] In one embodiment, the film attaching body 200 further includes a microswitch 272 installed on the fixed bottom plate 210 and electrically connected to the slide cylinder 270. The microswitch 272 closes when the film releasing movable plate 230 contacts the downward pressing height limiting block 250. Additionally, in this embodiment, the slide cylinder 270 is communicated with an external air source through a bent pipe 273, and the bent pipe 273 serves as an air source connecting member between the slide cylinder 270 and the external air source. An electromagnetic valve 274 for controlling the on-off of the air path of the slide cylinder 270, a T-shaped speed regulating valve 275 for controlling the air volume of the slide cylinder 270, and a Y-shaped three-way pipe 276 are further installed on the fixed bottom plate 210. The electromagnetic valve 274 is electrically connected to the microswitch 272. Thus, when the film releasing movable plate 230 contacts the downward pressing height limiting block 250, the moving contact at the end of the moving reed of the microswitch 272 quickly connects with the fixed contact, and the microswitch 272 closes, thereby triggering the electromagnetic valve 274, causing the electromagnetic valve 274 to control the opening of the air path switch of the slide cylinder 270, supplying the air source to the slide cylinder 270, and the slide cylinder 270 further pushing the push block 271 to push and press the film material 30 against the side wall of the inkjet base 20. Conversely, when the handheld movable pressing plate 100 is lifted, the film releasing movable plate 230 is separated from the microswitch 272, the intake electrical signal of the electromagnetic valve 274 is disconnected, the slide cylinder 270 stops intake, the telescopic rod of the slide cylinder 270 retracts and drives the push block 271 to retract together, so that the push block 271 leaves the side of the inkjet base 20, to avoid taking out the inkjet base 20 through the top pushing mechanism 260. In this embodiment, by setting the microswitch 272, it can be ensured that after the film is pressed in place each time, the slide cylinder 270 drives the push block 271 to automatically press the film material 30 against the side of the inkjet base 20, reducing the operation steps and saving time and labor costs. In addition, a support plate 211 is installed on the fixed bottom plate 210, and the positioning and placing plate 240 and the microswitch 272 are both fixed on the support plate 211.
