Description

Technical Field

[0001] The present invention relates to the technical field of film tearing, and particularly relates to a film tearing workbench. Background Art

[0002] In recent years, with the increasingly rich functions of electronic devices such as mobile phones or tablets, people's lifestyles have been greatly changed, and they have become an essential part of people's daily lives. As the importance of electronic devices in life increases day by day, there are more and more various accessory products supporting them, and the output of accessory product enterprises is also getting higher and higher.

[0003] During the process of product production and assembly by accessory manufacturers, many small sheet materials are required. Before assembly, the protective films on the surfaces of these small sheet materials need to be torn off. Previously, it was all done manually, but it was very easy to leave fingerprints on the small materials. Therefore, slowly, machines have replaced manual labor to achieve fully automatic film tearing. The small sheet materials are fixed on the workbench, and the protective film is torn off by the clamping jaws.

[0004] During the film tearing process, the protective film will exert a pulling force on the small material, which is likely to cause the small material to displace. In addition, due to the relatively thin structure of the small sheet material, it cannot withstand a large acting force during fixation. Therefore, during the film tearing process, it is necessary to always press on the small material through a pressing wheel. However, sometimes the surface of the small material is not flat, and in the existing film tearing device, the pressing wheel for pressing cannot be adaptively adjusted according to the different heights of the small material, resulting in very easy displacement of the small material and failure of film tearing. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the pressing roller cannot be adaptively adjusted according to the different heights of the small material, resulting in very easy displacement of the small material, and to propose a film tearing workbench.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The frame body is also fixedly installed with a clamping jaw air cylinder. The output end of the clamping jaw air cylinder is fixedly connected to the upper clamping jaw. The pressing assembly includes a translation frame vertically slidably connected to the frame body. A pressing wheel is rotatably connected to the bottom of the translation frame. The frame body is also fixedly installed with a pressing air cylinder. The output end of the pressing air cylinder is fixedly connected to a pushing plate. The pushing plate and the translation frame are connected by a first spring.

[0008] To improve the stability of adaptation, preferably, an adjusting cylinder is fixedly connected to the bottom of the pushing plate, and a connecting column is fixedly connected to the top of the translation frame. The connecting column extends into the adjusting cylinder. The first spring is connected between the connecting column and the pushing plate, and the first spring is located inside the adjusting cylinder.

[0009] To facilitate the adjustment of the horizontal position of the pressing wheel, preferably, it further includes a sliding frame vertically slidably connected to the frame body. The connecting column is fixedly connected to the top of the sliding frame. The translation frame is horizontally slidably connected to the sliding frame and is fixed by bolts.

[0010] Preferably, both the jaw assembly and the pressing assembly are designed in two groups.

[0011] A film tearing workbench further includes a clamping table, and a clamping groove is provided on the clamping table. Sliding grooves are further provided on both sides of the clamping groove, and a clamping plate is slidably connected in the sliding groove. A second spring is connected between the clamping plate and the side wall of the sliding groove. A first groove is provided on one side of the clamping table.

[0012] To improve the clamping effect, preferably, the clamping plate is composed of a support plate and a protrusion. The support plate is slidably connected in the sliding groove, the protrusion is located on the upper part of the support plate, and the protrusion faces the clamping groove.

[0013] To prevent the small material from moving during the film tearing process, preferably, an arc-shaped plate is vertically slidably connected to the clamping table. A connecting rod is fixedly connected to the bottom of the arc-shaped plate, and a fixing plate is fixedly connected to the bottom of the connecting rod. A tension spring is connected between the fixing plate and the bottom of the clamping table. A piston assembly is fixedly connected to the bottom of the clamping table, and the power end of the piston assembly is fixedly connected to the fixing plate. A first suction cup is provided in the clamping groove, and the piston assembly is connected to the first suction cup through a pipeline. The pressing wheel can abut against the arc-shaped plate. A second groove is provided on the translation frame.

[0014] To facilitate unloading, preferably, a top rod is vertically slidably connected in the clamping groove, and a top plate is fixedly connected to the top of the top rod. The top plate can move into the clamping groove. A connecting frame is fixedly connected to the bottom of the top rod, and a third spring is connected between the connecting frame and the bottom of the clamping table.

[0016] Preferably, a second suction cup is further provided in the clamping groove.

[0017] Compared with the prior art, the present invention provides a film tearing workbench, which has the following beneficial effects:

[0018] 1. In the process of film tearing, the pressing wheel of the adaptive film tearing assembly will always press on both sides of the small material, canceling out the upward pulling force generated during film tearing. Even if the surface of the small material is uneven, the pressing wheel will always be in contact with the surface of the small material under the action of the first spring, achieving the purpose that the height of the pressing wheel can be adaptively adjusted according to the surface of the small material, thereby effectively ensuring the reliability of film tearing and improving the success rate of film tearing.

[0019] 2. Through the cooperation of the arc-shaped plate and the pressing wheel, the film tearing workbench realizes that during the film tearing process, the fixing degree of the small material is strengthened where the protective film is torn, because the pulling force is the greatest here. It is strengthened specifically by the first suction cup and then automatically released under the action of the tension spring, thereby preventing the small material from moving during the film tearing process.

[0020] 3. After the film tearing is completed, the frame continues to move, the roller is in contact with the bottom of the inclined plate, and then drives the sliding plate to move upward. Furthermore, the top plate is driven to move upward through the ejector rod, so that the top plate moves into the card slot, and the small material is ejected from the card slot by the top plate, facilitating the staff to take it.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0033] Embodiment 1:

[0034] Refer to Figures 1-4, An adaptive film tearing assembly, including a frame 1 and a lifting cylinder 101. The output end of the lifting cylinder 101 is fixedly connected to the top of the frame 1. The lifting cylinder 101 is used to drive the entire frame 1 to move up and down. A jaw assembly 2 and a pressing assembly 3 are provided on the frame 1. The jaw assembly 2 includes a lower jaw 202 and an upper jaw 203. The lower jaw 202 is fixedly installed on the frame 1, and the upper jaw 203 is vertically slidably connected to the frame 1. The frame 1 is also fixedly installed with a jaw cylinder 201. The output end of the jaw cylinder 201 is fixedly connected to the upper jaw 203. The jaw cylinder 201 pushes the upper jaw 203 to approach or move away from the lower jaw 202; The pressing assembly 3 includes a translation frame 306 vertically slidably connected to the frame 1. A pressing wheel 307 is rotatably connected to the bottom of the translation frame 306. On both sides of the bottom of the translation frame 306, a pressing wheel 307 is rotatably connected. That is to say, there are two pressing wheels 307 at the bottom of each translation frame 306. The frame 1 is also fixedly installed with a pressing cylinder 301. The output end of the pressing cylinder 301 is fixedly connected to a pushing plate 302. The pushing plate 302 is connected to the translation frame 306 through a first spring 305.

[0035] Such as Figure 1 , The jaw assembly 2 and the pressing assembly 3 are both designed in two groups, respectively connected to both sides of the frame 1. Each group of jaw assemblies 2 is located in the middle of the corresponding pressing assembly 3, and the pressing assembly 3 is in the front and the jaw assembly 2 is in the back.

[0036] Each group of jaw assemblies 2 also has two lower jaws 202 and two upper jaws 203.

[0037] The lifting cylinder 101 is externally connected to a linear motion mechanism, such as a linear motor or a motor plus a lead screw, for driving the entire film tearing assembly to move horizontally.

[0038] During operation, first fix the small material that needs to have its film torn off, then move the frame 1 to one side of the small material, start the lifting cylinder 101, and drive the frame 1 to move downward. When it moves to a position where the lower jaw 202 is lower than the height of the protective film, then drive the frame 1 to move towards the small material through the linear motion mechanism. When it moves directly below the protective film, start the jaw cylinder 201, drive the upper jaw 203 to move downward, clamp the protective film through the upper jaw 203 and the lower jaw 202, and then make the frame 1 move upward through the lifting cylinder 101 so that the lower jaw 202 is slightly higher than the top of the small material. During the process of clamping the protective film, simultaneously start the pressing cylinder 301, drive the translation frame 306 to move downward, so that the pressing wheel 307 always presses on the small material, and then drive the entire frame 1 to move horizontally forward through the linear motion mechanism, thereby achieving the purpose of tearing the film.

[0039] During the film tearing process, the pressure wheel 307 will always press on both sides of the small material, rolling forward, always applying a downward pressure on the small material, which offsets the upward pulling force generated during film tearing, thereby preventing the small material from being displaced during the film tearing process. The translation frame 306 slides on the frame body 1. During the movement, even if the surface of the small material is uneven and has ups and downs, the pressure wheel 307 will always be against the surface of the small material through the force of the first spring 305, so that the height of the pressure wheel 307 can be adaptively adjusted according to the surface of the small material, thereby effectively ensuring the reliability of film tearing and improving the success rate of film tearing.

[0040] like Figure 3 and Figure 4 In order to improve the stability of the vertical movement of the translation frame 306, the overall technical solution was optimized.

[0041] The bottom of the push plate 302 is fixedly connected to an adjusting cylinder 304, the top of the translation frame 306 is fixedly connected to a connecting column 308, the connecting column 308 extends into the adjusting cylinder 304, the top of the connecting column 308 slides in the adjusting cylinder 304, the first spring 305 is connected between the connecting column 308 and the push plate 302, and the first spring 305 is located in the adjusting cylinder 304.

[0042] During the film tearing process, when the upper surface of the small material is uneven and has undulations, the pressure wheel 307 will move up and down through the translation frame 306, and slide vertically up and down on the frame body 1. The force applied to the connecting column 308 by the first spring 305 is ensured to ensure that the pressure wheel 307 is always in contact with the upper surface of the small material. By adjusting the cylinder 304 and the connecting column 308, the working stability is improved.

[0043] like Figure 3 The adaptive film tearing assembly disclosed in this embodiment also includes a sliding frame 303 vertically slidably connected to the frame body 1, and a connecting column 308 is fixedly connected to the top of the sliding frame 303; a translation frame 306 is horizontally slidably connected to the sliding frame 303, and the translation frame 306 is fixed by bolts.

[0044] The sliding frame 303 is provided with a sliding groove, and the translation frame 306 is stuck in the sliding groove and slides.

[0045] The sliding frame 303 can only slide on the frame body 1 and cannot be separated from the frame body 1. According to actual needs, when the horizontal position of the pressure wheel 307 needs to be adjusted, the translation frame 306 is horizontally slid on the sliding frame 303 for adjustment. After the adjustment is completed, it is fixed by bolts.

[0046] like Figure 1 The clamping jaw assembly 2 and the pressing assembly 3 are both designed in two groups.

[0047] The pressing wheels 307 on the two sets of pressing assemblies 3 are pressed on both sides of the small material respectively, and then the film is torn through the two sets of clamping jaw assemblies 2 to improve stability.

[0048] Embodiment 2:

[0049] Reference Figures 1-9 , which is basically the same as Example 1, and based on Example 1, a film tearing workbench is proposed.

[0050] A film tearing workbench also includes a clamping table 4, on which a card slot 405 is provided; sliding slots 404 are also provided on both sides of the card slot 405, with two sliding slots 404 on each side, a clamping plate 403 is slidably connected in the sliding slot 404, and a second spring 402 is connected between the clamping plate 403 and the side wall of the sliding slot 404.

[0051] A first groove 401 is provided on one side of the clamping platform 4 .

[0052] When tearing the film, the small material is placed in the card slot 405, and then the second spring 402 is used to make the card plate 403 abut against the side wall of the small material to achieve the purpose of clamping and fixing. At this time, the torn end of the protective film is suspended in the first groove 401, and the lower clamping jaw 202 is moved into the first groove 401, and then the clamping jaw cylinder 201 is started to clamp, and then the film is torn.

[0053] like Figure 6 and Figure 9 The card plate 403 is composed of a support plate 10 and a protrusion 1001. The support plate 10 is slidably connected in the sliding groove 404. The protrusion 1001 is located at the upper part of the support plate 10. The protrusion 1001 faces the card groove 405, and the top of the protrusion 1001 is inclined outward.

[0054] When the small material is fixed in the card slot 405 by the card plate 403, the staff can directly press the small material into the card slot 405 from above, and the small material will be stuck on the lower side of the protrusion 1001. The protrusion 1001 can be used to quickly fix the small material and then tear the film.

[0055] like Figures 5-8 An arc plate 501 is vertically slidably connected to the clamping platform 4, the top of the arc plate 501 extends out of the top of the clamping platform 4, the bottom of the arc plate 501 is fixedly connected to a connecting rod 5, and the bottom of the connecting rod 5 is fixedly connected to a fixed plate 504; a tension spring 503 is connected between the fixed plate 504 and the bottom of the clamping platform 4.

[0056] A piston assembly 502 is fixedly connected to the bottom of the clamping table 4, a power end of the piston assembly 502 is fixedly connected to the fixed plate 504, a first suction cup 505 is provided in the clamping groove 405, and the piston assembly 502 and the first suction cup 505 are connected via a pipe 506;

[0057] The pressing wheel 307 can abut against the arc-shaped plate 501.

[0058] The arc-shaped plates 501 corresponding thereto, the piston assemblies 502 and the first suction cups 505 are designed in 2 - 4 groups and are arranged in sequence on the clamping table 4. The number of arc-shaped plates 501 in each group is two, which are distributed on both sides of the card slot 405. The number of the first suction cups 505 in each group is 2 - 4. The first suction cups 505 and the arc-shaped plates 501 in each group are all on the same straight line.

[0059] Such as Figure 5 , the pressing assemblies 3 are designed in two groups. For the two pressing wheels 307 on the translation frame 306 of each pressing assembly 3, one always presses on the small material, and the other presses on the clamping table 4. During the movement, it will contact the arc-shaped plate 501 on the same side.

[0060] The piston assembly 502 includes a piston cylinder, a piston plate slidably connected in the piston cylinder, and a piston rod fixedly connected to the piston plate.

[0061] The bottom of the clamping table 4 is fixedly connected with the piston assembly 502, which means that the piston cylinder is fixed at the bottom of the clamping table 4.

[0062] The power end of the piston assembly 502 is fixedly connected with the fixing plate 504, which means that the end of the piston rod away from the piston plate is fixedly connected with the fixing plate 504.

[0063] During the forward movement of the pressing wheel 307, it will contact the arc-shaped plate 501, press the arc-shaped plate 501 to move downward, and then drive the piston plate to move downward through the fixing plate 504 and the piston rod. Through the pipeline 506, the first suction cups 505 in the same group generate suction force to suck the small material and prevent the small material from shifting during the film tearing.

[0064] When the pressing wheel 307 is disengaged from the arc-shaped plate 501, under the action of the tension spring 503, the arc-shaped plate 501 returns to the initial state, and the first suction cups 505 also lose the suction force.

[0065] Through the cooperation of the arc-shaped plate 501 and the pressing wheel 307, and the design of 2 - 4 groups of the arc-shaped plates 501 corresponding thereto, the piston assemblies 502 and the first suction cups 505, during the film tearing process, where the protective film is torn, the fixing degree of the small material at that place is enhanced because the pulling force here is the largest, and it is strengthened specifically through the first suction cups 505, and then it is automatically released under the action of the tension spring 503. Thus, during the film tearing process, the movement of the small material is prevented.

[0066] The anti-acting force of the tension spring 503 is smaller than that of the first spring 305, so that the arc-shaped plate 501 can move downward stably, and the first spring 305 will not be deformed.

[0067] Such as Figure 3 AndFigure 6 A second groove 7 is provided on the translation frame 306. When the translation frame 306 moves, the clamping plate 403 passes through the second groove 7 to prevent interference between the translation frame 306 and the clamping plate 403.

[0068] A second suction cup 701 is also provided in the card slot 405. The size of the second suction cup 701 is larger than that of the first suction cup 505. The second suction cup 701 is equivalent to the main suction cup and is located at the exact center of the card slot 405. A vacuum pump is also provided on the clamping table 4, and the vacuum pump is connected to the second suction cup 701.

[0069] During the film tearing process, the second suction cup 701 is always attracted to the small material by the vacuum pump. After the film tearing is completed, the second suction cup 701 loses suction under the action of the vacuum pump.

[0070] The small material has a sheet-like shape, a flat bottom, and an uneven upper surface.

[0071] Embodiment 3:

[0072] Refer to Figures 1-9 , which is basically the same as Embodiment 1. On the basis of Embodiment 1, the overall technical solution is further optimized to achieve the purpose of quickly discharging the material after film tearing.

[0073] A top rod 605 is vertically and slidably connected in the card slot 405. The top of the top rod 605 is fixedly connected to a top plate 606, and the top plate 606 can move into the card slot 405; the bottom of the top rod 605 is fixedly connected to a connecting frame 602. A third spring 604 is connected between the connecting frame 602 and the bottom of the clamping table 4. A guide rod 603 is fixedly connected to the bottom of the clamping table 4. The connecting frame 602 slides on the guide rod 603. A sliding plate 6 is vertically and slidably connected to the clamping table 4. The bottom of the sliding plate 6 is fixedly connected to the connecting frame 602. The top of the sliding plate 6 is fixedly connected to an inclined plate 601. A roller 9 is rotatably connected to the frame 1, and the roller 9 can be in contact with the bottom of the inclined plate 601; the sliding plate 6 is located on the side of the clamping table 4 away from the first groove 401.

[0074] There are two sliding plates 6, and an inclined plate 601 is provided on each sliding plate 6.

[0075] After the film tearing is completed, the frame 1 continues to move. At this time, the roller 9 is in contact with the bottom of the inclined plate 601, and then drives the sliding plate 6 to move upward, thereby driving the connecting frame 602 to move upward. The top plate 606 is driven to move upward by the top rod 605, so that the top plate 606 moves into the card slot 405, and the small material is ejected from the card slot 405 by the top plate 606, which is convenient for the staff to take. Then, when the frame 1 returns to the initial position to prepare for the next film tearing, under the action of the third spring 604, the top plate 606 and the inclined plate 601 both return to the initial position.

[0076] A stabilizing frame 8 is fixedly connected to the clamping table 4, and the stabilizing frame 8 is located on the side of the sliding plate 6 away from the clamping groove 405; the sliding plate 6 is in contact with the stabilizing frame 8.

[0077] When the roller 9 is in contact with the bottom of the inclined plate 601, a thrust will be applied to the sliding plate 6. By making the sliding plate 6 in contact with the stabilizing frame 8, the sliding plate 6 can be effectively prevented from tilting.

[0078] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
