Description

Technical Field

[0001] The utility model relates to the technical field of film tearing, in particular to a film tearing machine. Background Art

[0002] The protective film plays an important role in deep-hole plates, shallow-hole plates, and the biomedical field. It is usually pasted on the surface of the plate to prevent the surface of the plate from being eroded and damaged by chemical substances and the attachment of pollutants such as dust and impurities. However, the protective film is not the final component of the plate. In some subsequent manufacturing processes, the presence of the protective film may hinder the progress of these operations. Therefore, after completing its protection task, the protective film needs to be torn off from the surface of the plate.

[0003] Currently, the common practice is to manually tear off the protective film on the surface of the plate, but this has the problem of low film tearing efficiency, and the protective film is closely attached to the surface of the plate, often resulting in difficult film tearing. Similarly, for the protective film on the surface of other workpieces, the protective film needs to be torn off during the subsequent processing of the workpieces.

[0004] Therefore, there is an urgent need to develop a film tearing device to solve the problems of low efficiency and difficult film tearing in the prior art that rely on manual tearing of the protective film on the surface of the plate. Summary of the Invention

[0005] Aiming at the problem of low efficiency of manual film tearing in the prior art, the purpose of the utility model is to provide a film tearing machine to at least partially solve the above problems.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A film tearing machine includes a frame. A sliding frame is slidably connected to the frame in the vertical direction, and a lifting device for driving the sliding frame to move is fixedly installed on the frame. A material table for placing the workpiece to be torn with the film is slidably connected to the frame in the horizontal direction, and a transmission device for driving the material table to move is fixedly installed on the frame. A tape feeding roller and a tape winding roller are rotatably connected to the sliding frame, and a winding device for driving the tape winding roller to rotate is also fixedly installed on the sliding frame. The material table and the tape have partially the same movement path.

[0008] In some preferred embodiments, the axis of the tape feeding roller is perpendicular to the axis of the tape winding roller, and a tape guiding mechanism fixed to the sliding frame is further provided between the tape feeding roller and the tape winding roller.

[0009] In some preferred embodiments, the tape guiding mechanism includes a guiding frame, on which a guiding plate is provided. The included angles between the guiding edge of the guiding plate and the axes of both the tape unwinding roller and the tape winding roller are both 45°.

[0010] In some preferred embodiments, a guiding roller is rotatably connected to the guiding frame. The guiding roller is located on the upstream side of the guiding plate, and the axis of the guiding roller is parallel to the axis of the tape unwinding roller.

[0011] In some preferred embodiments, the transmission device includes two transmission wheels arranged at intervals along the sliding direction of the material table. A transmission belt is wound between the two transmission wheels. The transmission device further includes a transmission motor fixed on the machine frame and connected to one of the transmission wheels; the material table is fixedly connected to the transmission belt.

[0012] In some preferred embodiments, the machine frame includes a hollow bottom shell, on which a through groove parallel to the sliding direction of the material table is provided. The transmission belt is located inside the bottom shell. A connecting pin is fixed on one side of the bottom surface of the material table, and the connecting pin passes through the through groove and is connected to the transmission belt.

[0013] In some preferred embodiments, two clamping plates that are detachably fixed to each other are clamped on the transmission belt, and the connecting pin is connected to one of the clamping plates.

[0014] In some preferred embodiments, there are two through grooves that are parallel to each other, and a connecting pin fixed to the material table is inserted into each through groove.

[0015] In some preferred embodiments, the lifting device includes a lifting motor fixed on the machine frame. A lifting lead screw is connected to the motor shaft of the lifting motor. A lifting block is fixedly installed on the sliding frame, and the lifting block is adapted to the lifting lead screw.

[0016] In some preferred embodiments, a control panel is also fixedly installed on the machine frame, and the control panel is electrically connected to the lifting device, the transmission device, and the winding device.

[0017] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows: Through the settings of the tape unwinding roller, the tape winding roller, the lifting device, the material table, the winding device, and the transmission device, the tape can be brought closer to or away from the protective film on the workpiece by lifting. Then, under the action of the transmission device and the winding device, the tape and the material table can be driven to move. When the movement paths of the tape and the material table are no longer the same, the protective film adhered by the tape will be separated from the workpiece, thereby completing the film tearing operation.

Specific Embodiments

[0025] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] A film tearing machine, as Figure 1 shown, the film tearing machine includes a frame, the frame includes a substantially hollow bottom shell 1 and a housing 2 covering the top surface of the bottom shell 1. The housing 2 includes a fixed shell 21 and a movable shell 22. The fixed shell 21 is fixed to the top surface of the bottom shell 1 by welding or screws, and the movable shell 22 is pivotally connected to the fixed shell 21 through a hinge 23, and the space inside the housing 2 is exposed by flipping the movable shell 22.

[0027] As Figures 2-3As shown in the figure, a fixed plate 11 is fixedly installed on the top surface of the bottom case 1. A sliding frame 12 is slidably connected to the fixed plate 11 in the vertical direction. For example, one of them is fixed with a slide rail, and the other is provided with a chute that cooperates with the slide rail. A lifting device 3 for driving the sliding frame 12 to move is also fixedly installed on the bottom case 1.

[0028] The lifting device 3 includes a lifting motor 31, a lifting lead screw 32, and a lifting block 33. The lifting motor 31 is fixed to the bottom case 1 by screws, and usually a notch is also opened on the top surface of the bottom case 1 to facilitate the bottom of the lifting motor 31 to extend into it. The lifting lead screw 32 is fixed to the motor shaft of the lifting motor 31, for example, by welding or connecting through a coupling. The lifting block 33 is fixedly installed on the sliding frame 12, for example, by welding or screws, and a hole adapted to the lifting lead screw 32 is opened on the lifting block 33. In this way, by controlling the rotation direction of the lifting motor 31, the lifting block 33 and the sliding frame 12 fixed thereto can be driven to move up and down in the vertical direction.

[0029] A tape unwinding roller 4 and a tape rewinding roller 5 are rotatably connected to the sliding frame 12. Both of them have a rotating shaft and a drum fixed on the rotating shaft. The rotating shaft is rotatably connected to the sliding frame 12 through a bearing, and the drum is used for tape winding. Among them, the tape rewinding roller 5 provides the power for the tape to move between the tape unwinding roller 4 and the tape rewinding roller 5, and a winding device 6 for driving the tape rewinding roller 5 to rotate is also fixedly installed on the sliding frame 12. For example, the winding device 6 is configured as a motor, a servo motor, a variable-frequency motor, or a reduction motor, which is fixed to the sliding frame 12 by screws, and its output end is connected to the rotating shaft of the tape rewinding roller 5 through a coupling.

[0030] It is easy to understand that since the sliding frame 12 can be lifted and lowered, and the rotating shafts to which the tape unwinding roller 4 and the tape rewinding roller 5 belong usually have a certain length, two avoiding grooves for avoiding the rotating shafts to which the tape unwinding roller 4 and the tape rewinding roller 5 belong are also opened on the fixed plate 11. In addition, a notch for the bottom of the winding device 6 to pass through is also opened on the top surface of the bottom case 1 to avoid collision.

[0031] A material table 7 for placing the workpiece to be torn film is slidably connected to the top surface of the bottom case 1 in the horizontal direction. At the same time, a transmission device 8 for driving the material table 7 to move is also fixedly installed on the bottom case 1.

[0032] As Figures 4-5As shown in the figure, the transmission device 8 includes two transmission wheels 81 arranged at intervals along the sliding direction of the material table 7. For example, they are synchronous belt wheels, and their axles are rotatably connected to the bottom case 1 through bearings. A transmission belt 82, such as a synchronous belt, is wound around the two transmission wheels 81. The transmission device 8 further includes a transmission motor 83 fixed to one side of the top surface of the bottom case 1, and the transmission motor 83 is connected to the axle of one of the transmission wheels 81 through a coupling. The material table 7 is fixedly connected to the transmission belt 82.

[0033] In this embodiment, both the transmission wheels 81 and the transmission belt 82 are arranged inside the hollow structure of the bottom case 1, and the motor shaft of the transmission motor 83 is connected to the axle of one of the transmission wheels 81 after passing through the top surface of the bottom case 1. Correspondingly, a through groove 84 parallel to the sliding direction of the material table 7 is provided on the top surface of the bottom case 1, and a connecting pin 85 is fixed to one side of the bottom surface of the material table 7. The connecting pin 85 passes through the through groove 84 and is fixed to the transmission belt 82. For example, two clamping plates 86 connected to each other by screws are fixed to the transmission belt 82 in a clamping manner. A similar tooth profile is also provided on one of the clamping plates 86 facing the tooth profile of the transmission belt 82 to prevent the clamping plate 86 from sliding on the transmission belt 82. The other clamping plate 86 is used to fix to the connecting pin 85. For the convenience of connection, a transfer plate 87 arranged horizontally is provided on the other clamping plate 86, and the transfer plate 87 is connected to the connecting pin 85.

[0034] In this way, by controlling the forward and reverse rotation directions of the transmission motor 83, the material table 7 can be driven to move reciprocally along the direction guided by the through groove 84. It is easy to understand that two or more through grooves 84 can be provided and arranged at intervals along the direction perpendicular to the through groove 84. A connecting pin 85 fixed to the material table 7 is provided in each through groove 84, but only one of the connecting pins 85 needs to be connected to the transmission belt 82.

[0035] The material table 7 is located on one side below the tape, and the material table 7 and the tape have a partially same movement path.

[0036] For example, in this embodiment, the axis of the tape feeding roller 4 is perpendicular to the axis of the tape winding roller 5. After the tape is fed from the tape feeding roller 4, it first runs a certain distance along the same direction as the movement direction of the material table 7, and then turns 90° and is wound by the tape winding roller 5.

[0037] In addition, a tape guiding mechanism 9 fixed to the sliding frame 12 is further provided between the tape feeding roller 4 and the tape winding roller 5. As Figure 6As shown, the tape guiding mechanism 9 includes a guiding frame 91, on which a guiding plate 92 is fixed. The guiding plate 92 is horizontally arranged. At a corner of the guiding plate 92 away from the tape unwinding roller 4 and the tape winding roller 5, there is a guiding edge, and the angles between this guiding edge and the axes of both the tape unwinding roller 4 and the tape winding roller 5 are both 45°. The tape guiding mechanism 9 further includes a guiding roller 93 rotatably connected to the guiding frame 91. The guiding roller 93 is located on the upstream side of the guiding plate 92, and the axis of the guiding roller 93 is parallel to the axis of the tape unwinding roller 4.

[0038] The usage process of the film tearing machine provided by the embodiment of the present utility model is as follows:

[0039] The tape is wound on the tape unwinding roller 4. One end of the tape is folded 90° after passing through the tape guiding mechanism 9 (specifically, the guiding edge of the guiding plate 92) and then wound on the tape winding roller 5. The adhesive surface of the tape faces downward. The guiding roller 93 in the tape guiding mechanism 9 is located above the tape and provides rolling support for the non - adhesive back surface of the tape.

[0040] Place the workpiece to be film - torn on the material table 7. The transmission device 8 operates to drive the material table 7 below the tape unwinding roller 4. Specifically, the material table 7 is located below the tape between the tape guiding mechanism 9 and the tape unwinding roller 4.

[0041] Drive the sliding frame 12 to descend through the lifting device 3 until the tape adheres to the film on the surface of the workpiece to be film - torn; then start the transmission device 8 to drive the material table 7 to move away from the tape unwinding roller 4, and at the same time start the winding device 6 to drive the tape to wind. When the material table 7 moves to the guiding edge of the guiding plate 92, the movement direction of the tape changes, so as to tear the film from the workpiece and then wind it on the tape winding roller 5 until the film on the material table 7 is completely torn. Then the lifting device 3 acts in the reverse direction to drive the sliding frame 12 to rise. After replacing the new workpiece to be film - torn on the material table 7, repeat the above actions.

[0042] It is easy to understand that for the convenience of operation, the configured film tearing machine further includes a control panel 10 fixedly installed on the bottom shell 1. The control panel 10 is located outside the cover 2 for easy operation and observation. The control panel 10 is electrically connected to the lifting device 3, the transmission device 7, and the winding device 6. The user operates the control panel 10 to perform the film - tearing operation.

[0043] The above has described the embodiments of the present utility model in detail in conjunction with the drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
