Description

Technical Field

[0001] The utility model relates to the field of Mylar covering, in particular to a high-precision positioning Mylar covering device. Background Art

[0002] Mylar laminating operations are often performed manually or with a Mylar laminating device.

[0003] Among them, manual lamination has low work efficiency, and the force or placement used in each lamination cannot be guaranteed to be consistent, resulting in poor component quality. In addition, manual lamination requires a lot of manpower, resulting in high labor costs.

[0004] The Mylar laminating device mainly completes the Mylar laminating operation by first positioning the Mylar with the adhesive side facing up, then positioning and placing the machined part, and finally pressing the machined part down to coat the Mylar on the machined part. However, in existing product production, Mylar is directly crimped and laminated on the machined part, which may cause deviation, floating or bubbles, affecting production quality.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Utility Model Content

[0009] The covering assembly includes an upper base plate, a connecting plate, and a lower base plate arranged in sequence from top to bottom. The upper base plate and the lower base plate are fixedly connected, and the connecting plate and the lower base plate are connected by an elastic structure. The connecting plate is provided with a machined part support structure and a Mylar positioning structure that pass through the upper base plate.

[0010] In the natural state of the elastic structure, the machined parts supported by the machined parts supporting structure and the Mylar positioned by the Mylar positioning structure are arranged in a gap.

[0011] Preferably, the pressing mechanism includes a pressing cylinder, a floating joint and a pressing plate. The pressing cylinder is fixed on the top of the workbench, and the pressing plate is connected to the pressing cylinder via a floating joint.

[0012] Further preferably, the crimping cylinder is electrically connected to a PLC controller, and the PLC controller is connected to a time relay.

[0013] Preferably, the upper surface of the upper base plate is provided with a positioning groove for positioning the Mylar and the machined parts, and the edge of the positioning groove is provided with a guide block for positioning the machined parts.

[0014] Further preferably, an elastic pad for supporting Mylar is provided in the positioning groove, and the elastic pad is made of sponge or foamed silicone skin.

[0015] Preferably, the elastic structure includes a guide shaft, a spring and a linear bearing; wherein the linear bearing and the spring are both sleeved on the outside of the guide shaft, the upper end face of the linear bearing contacts the connecting plate, the lower end face contacts the top of the spring, and the guide shaft is fixedly arranged between the upper base plate and the lower base plate.

[0016] Preferably, the machined part support structure and the Mylar positioning structure both use a plurality of inverted pins, the bottom ends of the pins are positioned in slots on the connecting plate, and the top ends pass through the upper base plate.

[0017] Preferably, the top surface of the machined part support structure is higher than the top surface of the Mylar positioning structure, or is level with the top surface of the Mylar positioning structure.

[0018] Further preferably, a micro switch is provided on the rear side of the inner cavity of the workbench, the micro switch corresponds to the front and back of the covering component, and the micro switch is electrically connected to the PLC controller.

[0019] The working principle and advantages of this utility model are as follows:

[0020] The utility model is a special device composed of a workbench, a linear drive structure, a laminating component and a pressing mechanism. It can solve the problems of low work efficiency and poor quality in manual Mylar laminating, as well as the problem of deviation, floating or bubbles after the Mylar laminating machine adds parts due to inconsistent manual working techniques.

[0021] The utility model designs the laminating components so that a certain distance exists between the machined parts and the Mylar after they are placed, so as to prevent the two from adhering to each other in advance and causing defects such as bubbles and creases to remain after the Mylar lamination and pressing.

[0022] The pressing mechanism of the utility model is provided with a time relay for maintaining pressure, which maintains pressure for a period of time after the machined part and the Mylar come into contact, thereby extending the bubble exhaust time and further improving the film lamination quality.

[0023] The utility model can improve the pasting precision by arranging a guide block for positioning a machined part on the upper bottom plate of the pasting component and positioning the Mylar through the Mylar positioning structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See attached Figure 1-4 As shown, a high-precision positioning Mylar laminating device includes a workbench 1, which has a cavity inside and an entrance 101 on the front side. A pressing mechanism 2 is provided on the top of the cavity, and a laminating component 3 is provided on the bottom of the cavity. The laminating component 3 is linearly driven to enter and exit the cavity from the entrance 101.

[0038] The pressing mechanism 2 in this embodiment includes a crimping cylinder 21, a floating joint 22 and a pressing plate 23. The crimping cylinder 21 is fixed on the top of the workbench 1, and the bottom end of the crimping cylinder 21 extends into the cavity. The pressing plate 23 is connected to the bottom end of the crimping cylinder 21 through a floating joint 22. The floating joint 22 can solve the problem of the crimping plate 23 and the crimping cylinder 21 being out of alignment, thereby avoiding affecting the downward pressure.

[0039] In this embodiment, safety gratings 13 are also provided on both sides of the entrance 101. The safety gratings 13 are electrically connected to the PLC controller 9. When a person enters the entrance 101, the crimping cylinder 21 can be closed by the PLC controller 9 to ensure the safety of the operator. Figure 4 An emergency stop button 14 may also be provided on the workbench 1 so as to shut down the entire device at any time.

[0040] In order to ensure that the crimping cylinder 21 drives the pressing plate 23 to move stably, guide rods 24 are sleeved on the four corners of the pressing plate 23, and the two ends of the guide rods 24 are respectively fixed to the upper and lower surfaces of the cavity.

[0041] The crimping cylinder 21 is electrically connected to a PLC controller 9 , which is connected to a time relay 10 ; the crimping cylinder 21 is also provided with a magnetic induction switch for detecting the cylinder stroke.

[0042] When the crimping cylinder 21 drives the pressing plate 23 into place, the magnetic induction switch is turned on, and the PLC controller 9 starts the time relay 10. After a certain delay, the PLC controller 9 controls the crimping cylinder 21 to return, realizing the pressure holding time control of the Mylar bonding.

[0043] The control principle, control method and communication of the PLC controller 9 are existing technologies and are mature technologies that can be mastered by those skilled in the art. The control and communication between the PLC controller 9 and the cylinders, switches, etc. are also widely used in the existing technologies. Since they are not the invention points of this case, they will not be described in detail in this case.

[0044] The covering assembly 3 includes an upper base plate 31, a connecting plate 32 and a lower base plate 33 arranged in sequence from top to bottom. The upper base plate 31 and the lower base plate 33 are fixedly connected on both sides by a side plate 39, and the connecting plate 32 and the lower base plate 33 are connected by an elastic structure 34.

[0045] The upper surface of the upper base plate 31 is provided with a positioning groove 311 for positioning the Mylar and the machined parts. A guide block 35 is provided at the edge of the positioning groove 311 for positioning the machined parts. An elastic pad 36 is provided within the positioning groove 311 to support the Mylar. In this embodiment, the elastic pad 36 is made of foamed silicone rubber, but sponge can also be used in other embodiments.

[0046] The connecting plate 32 is provided with a machined part support structure 37 and a Mylar positioning structure 38 that pass through the upper base plate 31; in this embodiment, the top surface of the machined part support structure 37 is higher than the top surface of the Mylar positioning structure 38. In other embodiments, the machined part support structure 37 can also be level with the top surface of the Mylar positioning structure 38, as long as the positioned Mylar maintains a certain distance from the lower surface of the machined part; the machined part support structure 37 and the Mylar positioning structure 38 both use a number of inverted pins, the bottom end of the pin is positioned in the slot on the connecting plate 32, and the top end passes through the upper base plate 31.

[0047] The elastic structure 34 includes a guide shaft 341, a spring 342 and a linear bearing 343; wherein the linear bearing 343 and the spring 342 are both sleeved on the outside of the guide shaft 341, the upper end surface of the linear bearing 343 contacts the connecting plate 32, and the lower end surface contacts the top of the spring 342, and the guide shaft 341 is fixedly arranged between the upper base plate 31 and the lower base plate 33. Figure 2 .

[0048] When the elastic structure 34 is in a natural state, the machined parts supported by the machined parts supporting structure 37 and the Mylar positioned by the Mylar positioning structure 38 are arranged in a gap.

[0049] The linear drive described in this embodiment adopts a base plate cylinder 4, which is controlled by a start button 5 and is also electrically connected to a PLC controller 9. One end of the base plate cylinder 4 is fixedly connected to the lower base plate 33, and the two sides of the bottom of the lower base plate 33 slide with the slide rails 7 on the bottom machine through sliders 6 to ensure the stability of the movement of the covering component 3 and achieve precise mylar application.

[0050] A micro switch 8 is provided on the rear side of the inner cavity of the workbench 1. The micro switch 8 corresponds to the front and back of the coating component 3. The micro switch 8 is electrically connected to the PLC controller 9, which is fixedly mounted on the workbench 1. When the coating component 3 contacts the micro switch 8, the PLC controller 9 can drive the pressing mechanism 2 to perform the pressing work, thereby realizing the automatic coating work. Figure 3 .

[0051] Mylar tape working steps:

[0052] First, take the Mylar tape with the Mylar adhesive facing upwards and position it on the Mylar positioning structure 38. Then, position the machined part on the machined part support structure 37 using the guide block 35. (For machined parts with positioning pins 11, high-precision positioning bushings 12 can be provided on the upper base plate 31 to position the positioning pins 11, thereby further accurately positioning the machined part.)

[0053] Next, press the start button 5, the base cylinder 4 moves, and the covering component 3 is sent to the bottom of the pressing mechanism 2 through the two sliders 6. When the covering component 3 contacts the micro switch 8, the PLC controller 9 starts the pressing cylinder 21, and the pressing cylinder 21 drives the floating joint 22 and the pressure plate 23 to move down and apply force to the machined parts. The machined parts will drive the machined parts support structure 37, the Mylar positioning structure 38 and the connecting plate 32 to move downward, and the connecting plate 32 drives the linear bearing 343 to move downward, compressing the spring 342, and the machined parts and During Mylar pasting, the foamed silicone skin under the Mylar is in a compressed state. At this time, the crimping cylinder 21 presses and holds the pressure for a few seconds. After the pressure holding is completed, the pressure plate 23 is lifted, and the spring 342 is restored to make the machined parts support structure 37, the Mylar positioning structure 38 and the connecting plate 32 move upward, and the machined parts support structure 37 lifts up the machined parts after the Mylar pasting, and then the PLC controller 9 controls the movement of the bottom plate cylinder 4, and sends the pasting component 3 back to the starting point of the slider 6 through the two sliders 6. Finally, the employee removes the product after the Mylar pasting.
