Description

Technical Field

[0001] This utility model relates to the field of film application equipment technology. More specifically, it relates to a product film application device. Background Technology

[0002] Currently, products typically require a protective film during production to meet needs for scratch resistance, dust protection, or waterproofing. A film-applying device is an automated system that automatically applies the film to the product. The film application accuracy and efficiency are the main criteria for evaluating whether a film-applying device meets the production process requirements.

[0003] Existing film application devices typically pick up the film from the front, with the film's bonding surface facing down. If film application needs to be done from above the product, the product needs to be flipped so that the film application area faces upwards to complete the application. This process requires flipping the product, increasing equipment movement, reducing production efficiency, and there is a risk of dust contamination when the product is flipped.

[0041] The z-axis motor is rotatably connected to the synchronous pulley. The z-axis motor drives the synchronous pulley to rotate, thereby moving the synchronous belt. The movement of the synchronous belt causes the compensation module and the diaphragm on it to move in the vertical direction.

[0057] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings.

[0058] like Figure 1 The image shows a product film application device 1 according to an embodiment of this utility model. The product film application device 1 includes a product positioning component 10 and a film conveying component 20. The product positioning component 10 is used to position the product film at a first position. The film conveying component 20 includes a flipping module 220, a compensation module 230, and a spatial movement module 240. The flipping module 220 is used to flip the acquired film to a second position where the side of the film used for bonding with the product faces upwards. The compensation module 230 is used to adjust the angle of the film. The spatial movement module 240 is used to control the three-dimensional spatial displacement of the film, conveying the film at the second position to below the product at the first position so that the film bonds with the film application area at the bottom of the product.

[0059] In the above scheme, the product positioning component 10 is used to position the product at the first position for film application, accurately positioning the product to improve the accuracy of the film application position during subsequent product film application. After obtaining the film from the film supply machine 40, the flipping module 220 flips the film to a second position where the side of the film used to adhere to the product faces upwards. The compensation module 230 is used to adjust the angle of the film. The spatial movement module 240 transports the film at the second position to below the product at the first position so that the film adheres to the film application area at the bottom of the product, completing the film application. The film conveying component 20 flips the obtained film so that the film application side faces upwards and transports the flipped film to the first position for product film application to complete the product film application from below. Film application can be completed without flipping the product, improving film application efficiency and ensuring film application accuracy.

[0060] Please see Figure 1According to some embodiments of the present invention, optionally, the product positioning component 10 includes a first driving component (not shown in the figure) and a first positioning module. The first positioning module includes a positioning support component 112 and at least one first camera module 111. The first camera module 111 is fixedly installed in the positioning support component 112 and is used to position the first position of the product film. The first driving component drives the positioning support component 112 to move to the relative position of the carrier (not shown in the figure) carrying the product based on the product detection result of the first camera module 111 to obtain the first position of the product film.

[0061] It should be noted that the carrier of this utility model has a cutout at the position where the product is to be supported, so that the area of ​​the product to be covered with film is exposed below the carrier from the cutout position, so that the film can be attached to the product from below and the area of ​​the product to be covered with film, thus completing the product film application.

[0062] In the above scheme, the product positioning component 10 mainly consists of two parts: a first driving component and a first positioning module. The first driving component serves as a power source, providing driving force to control the movement and displacement of the first positioning module.

[0063] The first drive component can use a motor to provide driving force and control the first positioning module to move in the vertical direction, so as to adjust the relative position between the first positioning module and the product carrier and position the product to the first position through the positioning function of the first positioning module.

[0064] The first positioning module includes a positioning support component 112 and at least one first camera module 111. The first camera module 111 is fixedly mounted on the positioning support component 112 and is used to output the product detection result of whether the product is detected by visual inspection. The visual inspection algorithm can be a conventional visual inspection algorithm in the art, which will not be described in detail here.

[0065] The first driving component drives the positioning support component 112 to move based on the product inspection results, so that the relative position of the first camera module 111 and the product carrier reaches the predetermined condition, and the product is positioned in the first position. The structure of the first camera module 111 and the first positioning module efficiently and accurately positions the product in the first position to improve the accuracy of subsequent film application.

[0066] It should be noted that in this embodiment, the first camera module 111 can be an industrial camera. In other embodiments, the first camera module 111 can also be other image acquisition devices, and this application does not limit this.

[0067] Optional, such as Figure 1The first positioning module shown includes two first camera modules 111, each of which can position one product. Therefore, the film application device 1 in this specific example can apply film to two products at once, thereby improving production efficiency.

[0068] Please see Figure 2 According to some embodiments of this utility model, optionally, the positioning support assembly 112 includes a base plate 113 and a support plate 114 disposed on the base plate 113, and the first camera module 111 is fixedly mounted on the support plate 114. The lower surface of the base plate 113 is provided with a positioning pin 115 and a positioning block 116. The first driving assembly drives the first positioning module to move, so that the positioning pin 115 is nested with a pin hole on a carrier (not shown in the figure) carrying the product, and then drives the first positioning module to move axially downward along the pin hole so that the positioning block 116 abuts against the carrier.

[0069] In the above scheme, the positioning support component 112 uses the base plate 113 as the base carrier. A support plate 114 is provided above the base plate 113 to fix the first camera module 111 set in the vertical direction, so that the lens of the first camera module 111 can capture the product image below for visual inspection.

[0070] The first drive assembly moves the first positioning module downwards, causing the positioning pin 115 on the lower surface of the base plate 113 to nest with the pin hole on the product's carrier. The nesting of the pin hole and the positioning pin 115 achieves horizontal positioning between the base plate 113 and the carrier. Then, the first drive assembly controls the first positioning module to move downwards along the axial direction of the pin hole until the positioning block 116 on the lower surface of the base plate 113 abuts against the surface of the carrier. The contact between the positioning block 116 and the carrier, along with the thickness of the positioning block 116, achieves horizontal positioning between the base plate 113 and the carrier. The first camera module 111 can then output the first position of the product film application via visual inspection.

[0071] Please see Figures 1-2 The positioning support assembly 112 further includes a top plate 117 and a plurality of support columns 118 supporting the bottom plate 113 and the top plate 117. The first drive assembly is fixedly disposed on the upper surface of the top plate 117. The first drive assembly is fixed to the top of the top plate 117, and the top plate 117 needs to provide support for the first drive assembly. Therefore, the support columns 118 are used to connect the top plate 117 and the bottom plate 113 to support the top plate 117 and maintain the stability of the positioning support assembly 112.

[0072] Please see Figures 1-3According to some embodiments of the present invention, optionally, the base plate 113 is provided with a first through hole 119 in the area corresponding to the first camera module 111. The product positioning component 10 also includes a product adsorption structure, a pressure detection component 130, and a fixing structure.

[0073] The product adsorption structure extends through the first through hole 119 to the bottom plate 113 to adsorb and fix the product; the pressure detection component 130 is fixed to the product adsorption structure, including a pressure sensor 131 and a receiving part 132 for accommodating the pressure sensor 131; the fixing structure is fixedly connected to the bottom plate 113, and the receiving part 132 of the pressure detection component 130 is slidably fixed to the fixing structure in the vertical direction.

[0074] In the above scheme, the first driving component drives the positioning support component 112 to move, so that the positioning pin 115 is nested with the pin hole of the carrier and the positioning block 116 abuts against the carrier. The end of the product adsorption structure extends through the first through hole 119 to the bottom plate 113 to adsorb the product on the carrier. By adsorbing and fixing the product, the product is prevented from moving during the film application process, which would cause the film application position to be inaccurate.

[0075] The pressure sensor 131 of the pressure detection component 130 can detect the pressure transmitted by the product adsorption structure. During the product film application process, the pressure generated during the product contact with the film will be transmitted to the pressure sensor 131 through the product adsorption structure. That is, the pressure sensor 131 can detect the pressure that the product bears during the film application process. By monitoring the pressure, the pressure that the product bears during the film application process can be monitored in real time to avoid excessive pressure damaging the product.

[0076] Meanwhile, the receiving portion 132 of the pressure detection component 130 is slidably fixed to the fixed structure in the vertical direction. The position of the pressure sensor 131 is not fixed, and it can slide along the fixed structure when subjected to excessive pressure, so as to avoid excessive pressure being continuously applied to the product and protect the product.

[0077] Please see Figures 1-3According to some embodiments of the present invention, optionally, the fixing structure includes a fixing part 141, a vertical part 142, and a horizontal part 143 sequentially connected to the base plate 113. The bottom of the vertical part 142 is connected to the fixing part 141, and a linear slide rail 144 is provided on the vertical part 142, with the receiving part 132 slidably disposed on the linear slide rail 144; the horizontal part 143 is connected to the top of the vertical part 142, and a second through hole 145 is formed on the horizontal part 143. A connecting post 146 is provided on the top surface of the horizontal part 143, and an elastic element 147 is provided inside the cavity of the connecting post 146. One end of the elastic element 147 is fixed to the connecting post 146, and the other end passes through the second through hole 145 and abuts against the receiving part 132 of the pressure detection assembly 130.

[0078] In the above scheme, the second through hole 145 of the horizontal part 143 and the elastic element 147 in the connecting column 146 constitute a buffer mechanism. One end of the elastic element 147 is fixed, and the other end of the elastic element 147 abuts against the pressure detection component 130. The elastic element 147 absorbs the impact force of the product through deformation, avoiding rigid collision damage to the product. The pressure detection component 130 carries the pressure sensor 131 through the receiving part 132, and the receiving part 132 is slidably connected to the linear slide rail 144. When the product positioning component 10 moves down, the product adsorption structure first contacts the product and adsorbs and fixes the product. During this process, the pressure generated during the adsorption process can cause the receiving part 132 to slide upward along the linear slide rail 144 and compress the elastic element 147. The pressure sensor 131 senses the change in contact pressure in real time, and the deformation of the elastic element 147 also plays a buffering role, preventing the sudden increase in pressure from damaging the product.

[0079] Please see Figure 3 According to some embodiments of the present invention, optionally, the product adsorption structure includes an adsorption column 121 fixed to the bottom of the receiving portion, a vacuum interface 122 formed on the adsorption column 121, the interior of the adsorption column 121 is hollow to form a cavity and the bottom of the adsorption column 121 forms an opening, the vacuum interface 122 communicates with the cavity of the adsorption column 121; the vacuum interface 122 is connected to an external vacuum generating device, and the external vacuum generating device forms a vacuum environment in the cavity of the adsorption column 121 to adsorb the product at the opening.

[0080] In the above scheme, the hollow cavity inside the adsorption column 121 and the bottom opening form an adsorption channel. The vacuum interface 122 can be connected to an external vacuum generator. The external vacuum generator is connected to the hollow cavity of the adsorption column 121 through the vacuum interface 122. The external vacuum generator is activated to evacuate the hollow cavity of the adsorption column 121. By forming a vacuum environment, the product is fixed and adsorbed at the bottom opening of the adsorption column 121.

[0081] Optionally, a molded vacuum suction cup is provided at the bottom opening of the adsorption column 121. The molded vacuum suction cup is molded according to the shape of the product. The shape of the molded vacuum suction cup matches the shape of the product. When a vacuum environment is formed in the adsorption column 121, the molded vacuum suction cup can fit seamlessly and tightly with the product, avoiding the problem of air leakage due to gaps between the product and the bottom opening of the adsorption column 121, which would prevent the product from being stably fixed.

[0082] Optional, such as Figure 1 The first positioning module shown includes two first camera modules 111. These two first camera modules can apply film to two products simultaneously, improving production efficiency. Accordingly, the number and position of the product adsorption structure, pressure detection component, and fixing structure need to correspond to the number of first camera modules 111, i.e. Figure 1 The product positioning components shown also include two product adsorption structures, a pressure detection component 130, and a fixing structure that also need to be set to two positions corresponding to the first camera module 111, so as to pick up and position the two products respectively.

[0083] Please see Figure 1 According to some embodiments of the present invention, optionally, the product film application device 1 further includes a film positioning component 30 for detecting the film positioning result output by the film at the second position; the compensation module 230 is used to adjust the angle of the film based on the film positioning result output by the film positioning component 30.

[0084] In the above scheme, the membrane positioning component 30 is used to detect the membrane at the second position and output the membrane positioning result. To position and adjust the angle of the membrane, the product film application device 10 can be configured with the membrane positioning component 30 to acquire an image of the membrane flipped to the second position, obtain a membrane positioning image, and obtain the membrane positioning result based on existing visual detection algorithms. The compensation module 230 can then adjust the angle of the membrane based on the membrane positioning result. It should be noted that the compensation module can directly rotate the membrane by a preset angle to adjust its posture, without requiring the membrane positioning component 30 to assist in angle rotation.

[0085] In this embodiment, the compensation module 230 adjusts the angle of the membrane based on the membrane positioning result output by the membrane positioning component 30, so that the direction and angle of the membrane after adjustment reach the direction and angle corresponding to the required membrane posture, which can greatly improve the application accuracy of the membrane, especially irregularly shaped membranes. At the same time, the compensation module 230 can determine the position of the membrane relative to the membrane suction component 210 based on the membrane positioning result of the membrane positioning component 30, thereby obtaining the accurate position of the membrane and transporting the membrane to the first position for application based on the accurate position.

[0086] Please see Figure 1Optionally, the diaphragm positioning assembly 30 includes a second support frame 320, a second camera module 310, a light source 330, and a second driving assembly. The second camera module 310 is fixed to the second support frame 320, and the light source 330 is fixed to the second camera module 310 and located below it. A third through-hole is formed on the light source 330 to allow the second camera module 310 to acquire an image of the diaphragm at a second position through the third through-hole, and output the diaphragm positioning result. The second driving assembly can drive the second support frame 320 to move up and down so that the second camera module 310 can focus and capture a clear image of the diaphragm.

[0087] Specifically, the light source 330 is fixed below the second camera module 310 and adopts a ring light source 330 design to provide uniform and shadowless illumination for the diaphragm. The third through hole in the center of the light source 330 provides a shooting channel for the second camera module 310, so that the second camera module 310 can shoot the diaphragm on the diaphragm transport assembly 20 below.

[0088] Please see Figure 1 According to some embodiments of the present invention, optionally, the diaphragm conveying assembly 20 further includes a first support frame 211. The spatial movement module 240 is fixedly connected to the first support frame 211 and is used to drive the first support frame 211 to perform three-dimensional spatial displacement; the flipping module 220 is fixedly connected to the first support frame 211 and is used to control the first support frame 211 to flip along the horizontal axis so that the diaphragm flips to the side of the diaphragm used to adhere to the product facing upward; the compensation module 230 is fixedly disposed on the first support frame 211, and the compensation module 230 is fixedly equipped with a diaphragm suction assembly 210 for suctioning the diaphragm, and is used to control the rotation of the diaphragm suction assembly 210 to adjust the angle of the diaphragm.

[0089] In the above scheme, the film is usually attached to the centrifugal paper wound on the film supply machine 40. The film supply machine 40 rotates the centrifugal paper, and the film tearing component tears the film off the film supply machine 40 from the centrifugal paper. The film suction component 210 adsorbs and fixes the film torn from the film supply machine 40 onto the film suction component 210 to control the film and facilitate the adjustment of the film angle before transporting it to the first position for film application.

[0090] The film suction assembly 210 is used to suction the film from the film supply machine 40. The film conveying assembly 20 is used to control the film suction assembly 210 to flip so that the film is flipped to the second position, and based on the film positioning result output by the film positioning assembly 30, the film at the second position is conveyed to the product below the first position to complete the film application.

[0091] Please see Figure 1According to some embodiments of the present invention, optionally, the membrane conveying assembly 20 includes: a first support frame 211, on which the membrane suction assembly 210 is fixedly mounted; a spatial movement module 240, fixedly connected to the first support frame 211, for driving the first support frame 211 to perform spatial displacement at any position; a flipping module 220, fixedly connected to the first support frame 211, for controlling the first support frame 211 to flip along the horizontal axis so that the membrane flips to the side of the membrane used to adhere to the product facing upward; and a compensation module 230, fixedly disposed on the first support frame 211, for adjusting the angle of the membrane.

[0092] Specifically, after the film conveying assembly 20 acquires the film, the flipping module 220 first drives the first support frame 211 to flip in the vertical plane along the horizontal axis, flipping the film to the second position so that the bonding surface of the film used to attach to the product faces upward. After the film positioning assembly 30 outputs the film positioning result, the compensation module 230 adjusts the angle of the film. Then, the spatial movement module 240 drives the first support frame 211 to move so that the film picking assembly 210 on the first support frame 211 can transport the film to the bottom of the product at the first position, and attach the film to the film application area at the bottom of the product from below.

[0093] Please see Figure 1 According to some embodiments of this utility model, optionally, the spatial movement module 240 includes an x-movement module 241, a y-movement module 242, and a z-movement module 243. The x-movement module 241 and the y-movement module 242 are respectively used to realize the displacement of the first support frame 211 along the horizontal x-axis and y-axis; the flipping module 220 is fixed on one side of the first support frame 211, and the z-movement module 243 and the compensation module 230 are fixed on the other side, and the diaphragm suction assembly 210 is disposed on the compensation module 230; the z-movement module 243 is fixedly connected to the compensation module 230 and is used to control the displacement of the compensation module 230 and the diaphragm suction assembly 210 on it along the vertical z-axis.

[0094] Specifically, the spatial movement module 240 includes an x-movement module 241, a y-movement module 242, and a z-movement module 243. The x-movement module 241 and the y-movement module 242 are used to control the first support frame 211 to move in the x and y directions, respectively. The z-movement module 243 is disposed on the first support frame 211 and is used to directly drive the compensation module 230 to move, so as to control the vertical displacement of the membrane adsorbed and fixed on the compensation module 230.

[0095] After the compensation module 230 adjusts the diaphragm angle, the x-movement module 241 and y-movement module 242 work together to move the support frame horizontally in the x and y directions, transporting the diaphragm to the vertical direction corresponding to the first position. Then, the z-movement module 243 fine-tunes the height of the diaphragm on the compensation module 230, transporting the diaphragm to the first position to complete the film application. In the prior art, film application is mostly controlled by single-axis or dual-axis movement, resulting in low diaphragm accuracy. This application uses the three-axis movement of the spatial movement module 240 and the rotation of the flipping module 220 and the compensation module 230 to achieve five-axis position and angle control of the diaphragm, improving the relative position accuracy of the diaphragm and product alignment and film application, while also improving the accuracy of the diaphragm and product film application angle matching. The x-movement module 241 and y-movement module 242 can be implemented using existing movement modules, which are conventional techniques in this field and will not be described in detail here.

[0096] Please see Figures 4-5 According to some embodiments of this utility model, optionally, the z-moving module 243 includes a synchronous pulley 2431, a synchronous belt 2432, and a z-axis motor 2433. The z-axis motor 2433 is connected to the synchronous pulley 2431 and drives the synchronous pulley 2431 to rotate. The compensation module 230 is fixed to the synchronous belt 2432. Then, the z-axis motor 2433 drives the synchronous pulley 2431 to rotate, thereby driving the synchronous belt 2432 to move up and down. The synchronous belt 2432 drives the compensation module 230 fixed to it to move up and down, thereby driving the diaphragm on it to move in the vertical direction.

[0097] Optionally, the z-moving module is further provided with a first sensor 244 for detecting the displacement of the compensation module 230 in the z direction. When the displacement detected by the first sensor 244 reaches a preset limit, the z-moving module stops to avoid damage to the device structure.

[0098] Optionally, the diaphragm delivery assembly 20 is further provided with a second sensor 245 for detecting the rotation angle of the compensation module 230, so as to detect the adjustment of the diaphragm angle by the compensation module 230.

[0099] Please see Figure 1 According to some embodiments of the present invention, optionally, the membrane adsorption assembly 210 includes an adsorption member 212, which is used to fix and adsorb the membrane.

[0100] In the above scheme, when the membrane conveying assembly 20 moves to the picking position, the adsorption member 212 contacts the back side of the non-adhesive surface of the membrane. The adsorption member 212 is hollow inside and connected to an external vacuum generating device. The external vacuum generating device connected to the adsorption member 212 creates a vacuum environment in the adsorption member 212, which tightly adsorbs the membrane onto the adsorption member 212, thereby achieving the purpose of picking up the membrane.

[0101] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
