Description

Technical Field

[0001] The utility model relates to release paper peeling, in particular to a multi-head release paper peeling device. Background Art

[0002] Before gluing a workpiece fixed by a gluing process, it is usually necessary to tear off the release paper on the workpiece to expose the adhesive surface of the backing. The process of tearing off the release paper is called "tearing paper".

[0003] Existing release paper peeling equipment can only peel off the release paper on one adhesive backing. When a workpiece is provided with multiple adhesive backings, multiple release paper peeling equipment needs to be configured, which not only greatly increases the equipment cost, but also requires a large space volume.

[0004] Furthermore, the size of the workpiece is usually small, and the volume of the release paper peeling device is usually large. If multiple release paper peeling devices are set up to tear the paper on the workpiece at the same time, there will inevitably be a problem of interference between the release paper peeling devices.

[0005] Therefore, it is necessary to develop a multi-head release paper peeling device to solve the problem of mutual interference between release paper tearing devices when performing multi-position paper tearing in the prior art.

[0006] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0014] Wherein, the size of the transverse knife edge gradually decreases in the direction away from the longitudinal knife body to form a pointed top structure.

[0015] Optionally, the transverse knife edge extends obliquely upward in the direction away from the longitudinal knife body.

[0016] Optionally, the longitudinal knife body is provided with at least two knife body mounting holes arranged in sequence from top to bottom;

[0022] Optionally, a paper collecting component for recycling the release paper is provided at the side position of the bayonet assembly.

[0023] Optionally, the paper collecting component includes a clamping mechanism for clamping the release paper sent out by each bayonet assembly and a collecting box located below the clamping mechanism.

[0024] Optionally, the clamping mechanism includes:

[0025] A number of jaw cylinders corresponding to each bayonet assembly one by one;

[0026] A jaw mounting frame, and each jaw cylinder is mounted on the jaw mounting frame;

[0027] The paper receiving Y-direction linear driving mechanism, the driving end of the paper receiving Y-direction linear driving mechanism is connected to the jaw mounting bracket, and is used to drive each jaw cylinder to approach or move away from each bayonet component.

[0028] Optionally, the bayonet component, the collection box, and the jaw mounting bracket are all located between the paper tearing Y-direction linear driving mechanism and the paper receiving Y-direction linear driving mechanism.

[0029] The beneficial effect of the present utility model lies in: providing a multi-head release paper peeling device, a bayonet component is arranged at the position corresponding to each adhesive, and the Z-direction linear driving mechanism drives the bayonet to move upward to the piercing state of piercing the release paper; then, the paper tearing Y-direction linear driving mechanism drives the bayonet component to move horizontally, and synchronously, the Z-direction linear driving mechanism drives the bayonet component to move downward.

[0049] The present utility model provides a multi-head release paper peeling device, which is applicable to the application scenario of tearing the release paper on a workpiece with back glue, and can effectively solve the problem of mutual interference of the release paper tearing devices when tearing paper at multiple positions in the prior art.

[0050] See Figure 1 and Figure 2 As shown in Figure 2 and , the multi-head release paper peeling device provided in this embodiment includes a bayonet assembly 1, a Z-direction linear drive mechanism 2, and a paper tearing Y-direction linear drive mechanism 3.

[0051] The bayonet assembly 1 includes a bayonet holder 101 and at least two bayonets 102 mounted on the bayonet holder 101; wherein, the bayonets 102 are arranged in sequence along the length direction of the bayonet holder 101. The driving end of the Z-direction linear drive mechanism 2 is connected to the bayonet holder 101 for driving the bayonet holder 101 to move up and down along the height direction of the bayonet holder 101. The driving end of the paper tearing Y-direction linear drive mechanism 3 is connected to the Z-direction linear drive mechanism 2 for driving the Z-direction linear drive mechanism 2 to reciprocate along the width direction of the bayonet holder 101.

[0052] [[ID=II]]Wherein, the bayonet 102 has a piercing state in which it is driven by the Z-direction linear drive mechanism 2 to move upward relative to the adhesive layer to pierce the release paper 100; and has a paper tearing state in which it is driven by both the Z-direction linear drive mechanism 2 and the paper tearing Y-direction linear drive mechanism 3 to move obliquely downward relative to the adhesive layer to tear the release paper 100 from the adhesive layer.

[0053] In the multi-head release paper peeling device provided in this embodiment, a bayonet assembly 1 is provided at the position corresponding to each adhesive layer. The Z-direction linear drive mechanism 2 drives the bayonet 102 to move upward to the piercing state of piercing the release paper 100; then, the paper tearing Y-direction linear drive mechanism 3 drives the bayonet assembly 1 to move horizontally. Synchronously, the Z-direction linear drive mechanism 2 drives the bayonet assembly 1 to move downward. Under the combined action of the Z-direction linear drive mechanism 2 and the paper tearing Y-direction linear drive mechanism 3, the bayonet 102 will move obliquely downward to peel the release paper 100 from the adhesive layer.

[0054] In the multi-head release paper peeling device provided by the present utility model, the coordinated action of the Z-direction linear drive mechanism 2 and the paper tearing Y-direction linear drive mechanism 3 can enable multiple bayonet assemblies 1 to perform paper tearing operations synchronously, thereby avoiding the interference problem caused when multiple release paper peeling devices operate synchronously.

[0055] Optionally, the bayonet 102 includes a longitudinal blade body 1021 and a transverse blade 1022 fixedly provided at the top of the longitudinal blade body 1021; wherein, the size of the transverse blade 1022 gradually decreases in the direction away from the longitudinal blade body 1021 to form a pointed top structure 1022a.

[0056] Furthermore, the transverse blade 1022 extends obliquely upward in the direction away from the longitudinal blade body 1021.

[0057] The spire structure 1022a is the highest point of the bayonet 102. Therefore, when the Z-axis linear drive mechanism 2 drives the bayonet 102 to move upward, the spire structure 1022a will first contact the release paper 100 and pierce the release paper 100. Further, since the transverse blade 1022 is in an inclined state, when the paper tearing Y-axis linear drive mechanism 3 drives the bayonet 102 to move horizontally, the transverse blade 1022 can also apply a certain horizontal pulling force to the release paper 100, thereby tearing the release paper 100 from the adhesive backing.

[0058] In this embodiment, the longitudinal knife body 1021 is provided with at least two knife body mounting holes 1021a arranged in sequence from top to bottom. Further, at least one of the knife body mounting holes 1021a is an oval hole.

[0059] The multiple knife body mounting holes 1021a can facilitate the adjustment of the mounting height of the bayonet 102. Further, the oval hole provides a larger mounting margin and reduces the difficulty of hole alignment.

[0060] The bayonet knife holder 101 includes a knife holder plate 1011 and a number of bayonet fixing blocks 1012 corresponding to each bayonet 102. The knife holder plate 1011 is detachably mounted on the driving end of the Z-axis linear drive mechanism 2. Each of the bayonet fixing blocks 1012 is detachably mounted on the knife holder plate 1011; wherein, each bayonet 102 is firmly mounted in one of the bayonet fixing blocks 1012. Optionally, two detachable bayonet clamping plates 1012a are provided on the bayonet fixing block 1012 for clamping the longitudinal knife body 1021 of the bayonet 102.

[0061] The knife holder plate 1011 is detachably mounted on the driving end of the Z-axis linear drive mechanism 2. When it is necessary to perform paper tearing operations on different workpieces resulting in a change in the paper tearing position, the appropriate knife holder plate 1011 can be replaced. Further, when replacing bayonets 102 of different specifications, different bayonet fixing blocks 1012 can be replaced.

[0062] Optionally, both between the knife holder plate 1011 and the driving end of the Z-axis linear drive mechanism 2 and between the knife holder plate 1011 and each bayonet fixing block 1012 are firmly connected by fastening bolts.

[0063] See Figure 1 and Figure 3 , in this embodiment, a paper collecting component 4 for recycling the release paper 100 is provided at the side position of the bayonet component 1. Further, the paper collecting component 4 includes a clamping mechanism 401 for clamping the release paper 100 sent out by each bayonet component 1 and a collecting box 402 located below the clamping mechanism 401.

[0064] The clamping mechanism 401 includes a plurality of jaw cylinders 4011, jaw mounting brackets 4012, and a paper receiving Y-direction linear driving mechanism 4013, which are provided in one-to-one correspondence with each of the bayonet assemblies 1. Each of the jaw cylinders 4011 is mounted on the jaw mounting bracket 4012; the driving end of the paper receiving Y-direction linear driving mechanism 4013 is connected to the jaw mounting bracket 4012 and is used to drive each of the jaw cylinders 4011 to approach or move away from each of the bayonet assemblies 1.

[0065] After the Z-direction linear driving mechanism 2 and the paper tearing Y-direction linear driving mechanism 3 cooperate to drive the bayonet assembly 1 to tear out the release paper 100, the paper receiving Y-direction linear driving mechanism 4013 drives each of the jaw cylinders 4011 to approach each of the bayonet assemblies 1; then, each of the jaw cylinders 4011 clamps the corresponding release paper 100, and the paper receiving Y-direction linear driving mechanism 4013 drives each of the jaw cylinders 4011 to move away from each of the bayonet assemblies 1 and move to directly above the collection box 402. After the release paper 100 is released, the release paper 100 can automatically fall downward into the collection box 402 under the action of gravity, thereby completing the collection work of the release paper 100.

[0066] In this embodiment, the bayonet assembly 1, the collection box 402, and the jaw mounting bracket 4012 are all located between the paper tearing Y-direction linear driving mechanism 3 and the paper receiving Y-direction linear driving mechanism 4013. Such a structural layout can not only avoid the problem of mutual interference between components, but also make full use of the space between the paper tearing Y-direction linear driving mechanism 3 and the paper receiving Y-direction linear driving mechanism 4013, greatly improving the overall structural compactness.

[0067] In summary, the multi-head release paper peeling device provided in this embodiment has the following advantages:

[0068] ① The cooperation of the Z-direction linear driving mechanism 2 and the paper tearing Y-direction linear driving mechanism 3 can enable multiple bayonet assemblies 1 to perform paper tearing operations synchronously, thereby avoiding the interference problem caused by the synchronous operation of multiple release paper peeling devices;

[0069] ② The pointed top structure 1022a is the highest point of the bayonet 102. When the Z-direction linear driving mechanism 2 drives the bayonet 102 to move upward, the pointed top structure 1022a will first contact the release paper 100 and pierce the release paper 100; further, since the transverse blade 1022 is in an inclined state, when the bayonet 102 is driven to move horizontally, the transverse blade 1022 can also apply a horizontal pulling force to the release paper 100, thereby tearing the release paper 100 from the adhesive;

[0070] ③ The clamping mechanism 401 can recycle the torn release paper 100 into the collection box 402 to prevent the release paper 100 from being scattered everywhere;

[0071] ④ The structural layout is reasonable, which can not only avoid the problem of interference between components, but also make full use of the space between the paper tearing Y-direction linear driving mechanism 3 and the paper receiving Y-direction linear driving mechanism 4013, greatly improving the overall structural compactness.

[0072] It should be noted that the linear driving mechanism mentioned in the present utility model can be a cylinder, a hydraulic cylinder, an electric cylinder or a motor screw linear module, etc., and the rotary driving mechanism mentioned can be a brushed motor, a brushless motor or a rotary cylinder, etc. The present utility model does not limit the specific structural forms of the linear driving mechanism and the rotary driving mechanism.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application, using the content recorded in the text and drawings of the specification of the present application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
