Description

[0002] In the production process of PCB boards, a variety of different board / film materials are needed to make the final product. Therefore, in order to ensure the quality of the finished product, a layer of protective film will be covered on the surface of some fragile film materials and board materials to avoid quality defects such as surface damage during transportation.

[0003] Materials covered with a protective film need to have the protective film torn off before use for processing. Conventional film tearing methods are generally done manually.

Currently, there is a film tearing device that mainly separates the protective film from the sheet material by sticking tape on the protective film. This method requires frequent replacement of the tape during use. Using the tape as a consumable will increase production costs, and if the tape is not replaced in time after use or the tape loses its stickiness, the protective film cannot be torn off.

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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, an electrical connection, or mutual communication; 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 this application can be understood according to specific circumstances.

[0046] The present invention specifically discloses a film tearing device for PCB board processing, such as Figure 1 As shown, it comprises: a base 1, on which a feeding area, an intermediate film-tearing area and a terminal unloading area are arranged from left to right in sequence, the feeding area is used to store sheet materials and film materials that need to be unfilmed, and transfer the stored sheet materials to the intermediate film-tearing area and the terminal unloading area; the intermediate film-tearing area is used to perform film-tearing operations on the sheet materials provided by the feeding area; the function of the terminal unloading area is to take the sheet materials after film-tearing from the feeding area;

[0047] according to Figure 2As shown, the feeding area includes: a feeding rack 2 slidably connected to the left side of the base 1 by installing a slide rail 21 at the bottom, and vertical side panels 22 are fixedly installed around the feeding rack 2. When in use, the feeding rack 2 is pulled out, and the materials that need to be torn off are stacked in the feeding rack 2; linear guide rails 3 are installed on the base 1 on both sides of the feeding rack 2, and a moving rack 4 is jointly driven and connected to the linear guide rails 3 on both sides. Under the drive of the linear guide rails 3, the moving rack 4 moves horizontally above the feeding rack 2, and a first push rod 5 is fixedly installed at the center of the moving rack 4 , a rectangular adsorption plate 6 is slidably installed at the bottom of the moving frame 4 through a guide rod 61, and air holes are opened on the surface of the rectangular adsorption plate 6. When the side of the rectangular adsorption plate 6 with air holes is in contact with the surface of the material, air is sucked through the air pipe, and the material can be adsorbed on the surface of the plate. The movable rod of the first push rod 5 passes through the moving frame 4 and is connected to the rectangular adsorption plate 6. After the rectangular adsorption plate 6 follows the moving frame 4 to move above the feeding frame 2, the first push rod 5 drives the rectangular adsorption plate 6 to move downward, so that the rectangular adsorption plate 6 is in contact with the surface of the material and absorbs the material; wherein, according to Figure 4 and Fig.12 As shown, a fixing plate 14 is fixedly installed on the side wall of the side plate 22, and a plurality of bristles 141 are protrudingly installed on the fixing plate 14 at even intervals. The side walls around the rectangular adsorption plate 6 are provided with inner recesses 142 for allowing the bristles 141 to pass through. Specifically, in the process of the rectangular adsorption plate 6 adsorbing the material and moving it upward, the edge of the material will contact the bristles 141, and the bristles 141 will bend and press against the edge of the material. If there are multiple sheets of material that adhere together due to negative pressure and move upward with the rectangular adsorption plate 6, they will be scraped off under the action of the bristles 141, thereby avoiding the situation where the rectangular adsorption plate 6 adsorbs multiple sheets of material.

[0048] according to Figure 3 and Figure 5As shown, the middle film tearing area includes: a collecting ring 7 fixedly installed in the middle of the base 1, a containing shell 8 installed on the base 1 inside the collecting ring 7, and located at the center of the collecting ring 7, a bionic claw 82 is installed on the containing shell 8, and the bionic claw 82 is made of elastic soft rubber. A plurality of elastic tentacles 821 are arranged at intervals on the bionic claw 82, and the ends of the elastic tentacles 821 are provided with end contact portions 822 exceeding their width, and a clamping mechanism is installed on the base 1 close to the containing shell 8, and the clamping mechanism is used to clamp the protective film of the lifted part; specifically, the diagonal line of the rectangular adsorption plate 6 on the moving frame 4 is parallel to the linear guide rail 3, and after the rectangular adsorption plate 6 adsorbs the material, the moving frame 4 starts to move, and the moment during the movement The top corner of the rectangular adsorption plate 6 contacts with the bionic claw 82, so that the top corner of the material on the rectangular adsorption plate 6 will also contact with the elastic tentacle 821 of the bionic claw 82 and bend and deform. In the process of contact, the protective film covering the material will be partially lifted up by friction in the process of contact with the elastic tentacle 821, especially under the friction of the end contact part 822, multiple end contact parts 822 contact one by one to quickly lift up the protective film. After the protective film is lifted up, the part of the protective film is clamped by the clamping mechanism. Then, the rectangular adsorption plate 6 moves with the moving frame 4 and continues to translate with the material. In the process of translation, the protective film is torn off from the material, and the torn protective film falls into the collection ring 7.

[0049] Among them, Figure 5 and Figure 6 As shown, the bionic claw 82 and the accommodating shell 8 are connected together by a connecting plate 83. Two connecting plates 83 are provided, which are additionally arranged between the bionic claw 82 and the accommodating shell 8. One end of the two connecting plates 83 is hinged to the two sides of the bionic claw 82, and the other end is hinged to the accommodating shell 8. A third push rod 81 is also installed between the bionic claw 82 and the accommodating shell 8. The third push rod 81 is fixedly installed in the accommodating shell 8, and the movable rod is connected to the middle part of the bionic claw 82; the bionic claw 82 is bent and deformed under the push of the third push rod 81; in this way, The purpose of the arrangement is that when the bionic claw 82 is pushed upward by the third push rod 81, each elastic tentacle 821 of the bionic claw 82 bends and spreads outward, and when in contact with the protective film, the end contact portion 822 of each elastic tentacle 821 will maintain a certain distance, which helps to better lift the protective film. After the protective film is lifted, the bionic claw 82 is pulled down by the third push rod 81, and the end contact portion 822 on the elastic tentacle 821 will clamp the protective film to further tear the protective film.

[0050] Among them, according to Figure 7As shown, a reinforcing bone 841 is embedded inside the elastic tentacle 821 of the bionic claw 82, and a bone contact portion 842 is provided at the end of the reinforcing bone 841 at the end contact portion 822. The reinforcing bone 841 has a certain hardness, and the main function of the reinforcing bone 841 is to enhance the supporting strength of the elastic tentacle 821. Since the elastic tentacle 821 needs to be made of soft soft rubber, it will produce a large deformation when it touches the rectangular adsorption plate 6. At this time, if the pressure of the end contact portion 822 of the elastic tentacle 821 against the protective film is not enough, the protective film cannot be effectively lifted up. Therefore, embedding the reinforcing bone 841 in the elastic tentacle 821 can ensure that the elastic tentacle 821 has enough pressure against the protective film.

[0051] according to Figure 1 and Figure 4 As shown, the material after film tearing is moved to the terminal unloading area through the moving frame 4, and the terminal unloading area includes: a first motor 62 installed on the right side of the base 1, and a rectangular adsorption plate 6 is installed on the output shaft of the first motor 62. Since the rectangular adsorption plate 6 on the moving frame 4 is installed on the moving frame 4 after being deflected at an angle, after the rectangular adsorption plate 6 carrying the material moves to the top of the rectangular adsorption plate 6 in the terminal unloading area, the rectangular adsorption plate 6 in the terminal unloading area is driven to rotate by the first motor 62. After the angles of the two rectangular adsorption plates 6 are aligned, the first push rod 5 drives the rectangular adsorption plate 6 on the moving frame 4 to move downward. After the two rectangular adsorption plates 6 are fitted, the material is sandwiched in the middle, and the upper rectangular adsorption plate 6 no longer adsorbs the material, but the lower rectangular adsorption plate 6 adsorbs the material. Then the moving frame 4 returns to the top of the feeding frame 2, and the first motor 62 drives the rectangular adsorption plate 6 to rotate and correct, and then waits for the material grabber to grab the material that has been torn off the film.

[0052] like Figure 8 As shown, the clamping mechanism includes: a support frame 9 arranged on the base 1, a transmission shaft 92 is rotatably installed on both sides of the support frame 9, a worm 93 is fixedly connected to the top of the transmission shaft 92, and clamping jaws 94 are symmetrically hingedly installed on both sides of the top of the support frame 9, and a worm wheel 95 is fixedly installed on the hinge shaft of the clamping jaw 94. The worm wheel 95 rotates with the swing of the clamping jaw 94, and the worm wheel 95 and the worm 93 are meshed for transmission, so that the rotation of the transmission shaft 92 can rotate the worm wheel 95, thereby causing the clamping jaw 94 to swing on the support frame 9, and a through hole 97 is opened on the clamping jaw 94. To avoid collision and interference between the clamping jaws 94 and the worm 93 when swinging; a second motor 98 is fixedly installed in the middle of the lower part of the support frame 9, and the second motor 98 and the transmission shaft 92 are driven by a pulley set 99; specifically, after a corner of the protective film is torn off, the second motor 98 drives the transmission shaft 92 to rotate, thereby making the clamping jaws 94 on both sides of the support frame 9 move closer to each other, and the clamping end 96 of the clamping jaw 94 is provided with concave and convex patterns. After the clamping end 96 contacts each other, the protective film on the top can be clamped, and as the material leaves, the protective film is torn off.

[0053] The rectangular adsorption plate 6 carries the material and during the movement, the top corner of the material and the bionic claw 82 are in friction contact, and the end contact part 822 of the multiple elastic tentacles 821 arranged on the bionic claw 82 is used to rub up a corner of the protective film on the material in a stacked friction manner. The part with a raised corner is then clamped by the clamping mechanism, and the protective film is torn off during the movement of the material. The film tearing process is simple and effective and does not easily damage the material. No consumables are required to assist in the entire film tearing process, which saves production costs.

[0054] A reinforcing bone 841 is added inside the bionic claw 82 to ensure that the bionic claw 82 can maintain a certain strength and hardness when in use, so as to prevent the bionic claw 82 from being too soft and reducing the film peeling effect.

[0055] according to Figure 3 , Fig. 9 and Fig.10 As shown, the film tearing module is formed by combining the clamping mechanism, the containing shell 8 and the bionic claw 82, which specifically includes: a chassis 10 centrally mounted on the base 1 in the collecting ring 7, the clamping mechanism mounted on the chassis 10, an intermediate plate 91 fixedly mounted in the middle of the support frame 9 of the clamping mechanism, an electric push block 101 fixedly mounted on the side wall of the support frame 9, the containing shell 8 is slidably mounted on the support frame 9 and is located between the two clamping claws 94, the containing shell 8 is separated from the second motor 98 by the intermediate plate 91, and the movable push block 101 on the electric push block 101 is fixedly mounted on the side wall of the support frame 9. The plate 102 is fixedly connected to the containing shell 8; specifically, when the film tearing module is in use, the clamping claw 94 of the clamping mechanism is unfolded, the electric push block 101 pushes the containing shell 8 to move upward, and the movable frame 4 moves forward with the material and contacts the bionic claw 82. When the protective film on the material is torn off, the electric push block 101 moves the containing shell 8 downward, and then the second motor 98 drives the clamping claw 94 to close, thereby clamping the protective film, and the protective film is torn off as the material moves. Such a setting can reduce space occupancy, and the coordination between the bionic claw 82 and the clamping mechanism is smoother.

[0056] according to Figure 2 As shown, an extension frame 63 is fixedly installed on the top corner of the rectangular adsorption plate 6 on the moving frame 4 facing the bionic claw 82, a second push rod 64 is fixedly installed on the top of the extension frame 63, and a film tearing module is fixedly installed on the movable rod of the second push rod 64; specifically, when it is necessary to tear the film on both sides of the material, after the protective film on the bottom side of the material has been torn off, the material is transferred to the terminal unloading area, and in the process of the moving frame 4 moving back, the second push rod 64 drives the film tearing module to move downward, and the clamping jaw 94 is unfolded to make the bionic claw 82 rest on the upper surface of the material, and rub the protective film to lift up during the movement of the moving frame 4, and then the bionic claw 82 is retracted, and the clamping jaw 94 is used to clamp the lifted protective film, and the protective film is pulled above the collecting ring 7 and thrown down, thereby completing the double-sided film tearing.

[0057] Among them, according to Figure 3 and Fig.11 As shown, a gear ring 11 is rotatably connected in the lower part of the collecting ring 7, a gear 111 meshes with the gear ring 11 and drives the gear ring 11 to rotate through a third motor 1111 installed at the bottom of the base 1, columns 112 are evenly installed on the gear ring 11, two swing rods 113 are hingedly installed on the columns 112, and the swing rods 113 are kept fixed toward the center of the collecting ring 7 by torsion springs, a drop opening 114 is opened on the base 1 at an eccentric position in the collecting ring 7, a semicircular intercepting plate 115 is fixed above the drop opening 114, and a scraping opening 116 for allowing the swing rod 113 to enter is opened on the intercepting plate 115, and a protective ring 12 is fixed on the gear ring 11, and the gear 111 and the gear ring 11 are covered to prevent the protective film from being stuck in the clamping teeth during the meshing and rotation of the gear ring 11 and the gear 111; Specifically, after the protective film falls into the collecting ring 7, in order to prevent the protective film from covering the clamping claw 94, the third motor 1111 drives the ring gear 11 to rotate, and the rocker arm 113 and the column 112 rotate with the ring gear 11, and the protective film in the collecting ring 7 begins to move toward the drop port 114 under the push of the rotating rocker arm 113, and after the rocker arm 113 rotates and touches the intercepting plate 115, the rocker arm 113 enters the scraping port 116 and during the continuous rotation, the protective film on the rocker arm 113 is scraped off by the intercepting plate 115, and the scraped protective film will fall from the drop port 114, and accordingly, a collection container can be placed under the drop port 114 to collect the protective film, and the rocker arm 113 adaptively deflects in contact with the intercepting plate 115 until it straightens itself after breaking contact.

[0058] according to Figure 3 As shown, a hot nozzle 13 is installed on the intercepting plate 115, and the jet direction of the hot nozzle 13 is toward the drop port 114. An external air inlet pipe 131 is installed on the hot nozzle 13. When in use, air is added to the hot nozzle 13 through the air inlet pipe 131 and heated. At this time, the protective film at the drop port 114 is heated, and the protective film shrinks due to the heat, further reducing the space occupied by the protective film, allowing it to fall from the drop port 114 better, and preventing the protective film from being stuck at the drop port 114.

[0059] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
