Description

Technical Field

[0001] This utility model belongs to the field of automated production and relates to a transfer device for feeding antistatic film. Background Technology

[0002] In the manufacturing process of strain gauges, multiple films, such as PTFE and polyimide films with thicknesses ranging from 20 to 40 micrometers, are required for stacking and lamination. The conventional operation involves collecting the films in stacks after cleaning, and then manually separating, aligning, stacking, and laminating them individually according to process specifications during the stacking process. It is crucial that no more or fewer films are added during the process; otherwise, the peel strength of the entire stack of strain gauges will fail to meet standards after lamination. Analysis of the conventional operation revealed the following problems in the production process: 1) Non-value-creating actions such as tidying up the films exist. 2) During the film stacking process, multiple films are sometimes misjudged as single films and stacked, affecting the quality of the stack. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a transfer device for feeding antistatic film, which improves the reliability of single-sheet feeding of film in the stacking equipment and improves the overall pass rate of strain gauges after lamination.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A transfer device for feeding antistatic film includes a mounting base plate, a top plate, a connecting shaft, multiple trays, and multiple support pads; The connecting shaft is located between the mounting base plate and the top plate, connecting the two. Multiple trays are sleeved on the connecting shaft, and each tray carries a film. Multiple support pads are sleeved on the connecting shaft and are alternately spaced with the trays on the connecting shaft. Each support pad is located between two adjacent trays, and the outer peripheral wall of the support pad limits the rear edge and left and right edges of the film. Multiple limiting rods connect the mounting base plate and the top plate to limit the front edge and left and right edges of the film.

[0005] Preferably, the mounting base plate, support plate, and top plate are all E-shaped hollow structures.

[0006] Preferably, the tray is made of an antistatic non-metallic material.

[0007] Preferably, the support pad has a circular cylindrical structure and is made of an antistatic non-metallic material.

[0008] Preferably, the mounting base plate has a tapered limiting hole.

[0009] Preferably, a magnetic locking block is provided on the lower surface of the mounting base plate.

[0010] Preferably, a handle is provided on the upper surface of the top plate.

[0011] Preferably, the handle has a U-shaped structure and the surface is designed with positioning bosses and anti-slip bumps.

[0012] Preferably, the mounting base plate and top plate are provided with multiple countersunk connection holes. After the connecting shaft passes through the support plate and the support pad, its two ends are connected to the countersunk connection holes on the mounting base plate and top plate, respectively.

[0013] Preferably, both the mounting base plate and the top plate are provided with limiting holes for installing the limiting rod, and the limiting rod is detachably installed in the limiting holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention solves the technical problem of difficulty in single-sheet separation and feeding of films due to electrostatic adhesion by using a stacked structure of trays and support pads, combined with limiting rods, to effectively fix the film. Compared with existing technologies, this invention achieves automatic docking of automated equipment in upstream and downstream processes, eliminates redundant manual film handling, overcomes the problem of misjudging the number of films during manual operation, and thus significantly improves the reliability and accuracy of single-sheet film feeding in automated stacking equipment, ensuring product quality, increasing production efficiency and pass rate, while also reducing the labor intensity of workers and reducing labor costs.

[0022] like Figure 1 As shown, this embodiment describes a transfer device for feeding antistatic film, which includes a mounting base plate 1, a support plate 2, a support pad 3, a connecting shaft 4, a top plate 5, a handle 6, a limiting rod 7, a film 8, a conical positioning pin, a magnetic locking block, fastening screws, and elastic washers.

[0023] like Figure 2As shown, the mounting base plate 1 is located on the bottom surface of the conveying device. It is made of stainless steel and has a hollowed-out design. The mounting base plate 1 includes a rear side plate, and left and right side plates and a middle plate that are vertically connected to the two sides and the middle of the rear side plate. It has an E-shaped hollowed-out structure. The hollowed-out part plays a role in avoiding interference with the adsorbed gold parts during the picking up of the film 8. The lower surface of the E-shaped mounting base plate 1 has a groove in the center, which can be used to fasten the magnetic locking block with a fastening screw. After fastening, the exposed surface of the magnetic locking block is flush with the lower surface of the mounting base plate 1. Four limiting holes 9 are machined at the center of the left and right side plates and at the front end of the mounting base plate 1. The limiting holes 9 are tapered holes, with the large end of the tapered hole facing the downward surface and the small end facing the upward surface. They are used for quick positioning and docking with the tapered pins installed at the loading and unloading positions of each automated equipment. Five The countersunk connection hole is located at the center of the rear side plate. There is a rear countersunk connection hole 12b' at the center of the rear side plate. There is a left countersunk connection hole 10c' at the front and rear ends of the left side plate. There is a right countersunk connection hole 11d' at the front and rear ends of the right side plate. The countersunk holes face downwards. The support pad 3 at the rear countersunk connection hole 12b' limits the rear edge of the film 8. The support pads 3 at the left countersunk connection hole 10b' and the right countersunk connection hole 11d' limit the left and right edges of the film 8. The distance between the two limiting holes 9 at the front end is smaller than the distance between the side countersunk connection hole and the right countersunk connection hole 11d'. The four limiting holes 9 are used to cooperate with the limiting rod 7 to limit the left, right and front edges of the finished film 8. By limiting the film 8 around the perimeter, it is ensured that the film 8 does not slip during the transfer process.

[0024] The plurality of trays 2 are located between the mounting base plate 1 and the top plate 5, and adjacent trays 2 are separated by support pads 3. The trays 2 are formed from non-metallic materials that are smooth, flat, not easily deformed, lightweight, and antistatic. Figure 3 As shown, it has an E-shaped hollow structure. The hollow part serves to avoid interference with the adsorbed gold parts during the picking up of the film 8. The support plate 2 provides support for the film 8. Five light holes are processed at the positions corresponding to the five countersunk connection holes of the mounting base plate 1. Specifically, a rear connection hole 15 is provided at the center of the rear side plate, a left connection hole 13 is provided at the front and rear ends of the left side plate, and a right connection hole 14 is provided at the front and rear ends of the right side plate. The connection holes and the connecting shaft 4 are in a micro-clear gap fit. When the connecting shaft 4 passes through each support plate 2, there is no obvious peripheral shaking.

[0025] like Figure 4As shown, the support pad 3 is made of a smooth, anti-static non-metallic material, forming a cylindrical structure with a thickness equal to the distance between the upper and lower trays. This prevents the adsorption head from affecting the adjacent layers of film 8 when inserting or removing the film 8, and serves to isolate and elevate the adjacent trays 2. The support pad 3 has a hollow concentric circle structure with both its inner and outer diameters being circular. The inner diameter has a slight clearance fit with the connecting shaft 4, so that the support pad 3 does not wobble significantly after the connecting shaft 4 passes through it. After assembly, the outer diameter of the support pad 3 limits the rear edge and left and right edges of the film 8.

[0026] The connecting shaft 4 is machined with a chrome-plated optical shaft, and its length is the sum of n layers of tray 2 and (n+1) layers of support pad 3, where n is the number of layers of film 8 that the transfer device can carry. The center of each end of the connecting shaft 4 is machined with threaded holes corresponding to fastening screws, which are used to fasten the connecting shaft 4 to the mounting base plate 1 and the top plate 5.

[0027] like Figure 5 As shown, the top plate 5 is located on the top surface of the transfer device. It is made of stainless steel and has a hollowed-out E-shaped structure. The hollowed-out part serves to avoid interference with the adsorption of the metal parts during the picking up of the film 8. Two handle holes 16 are machined on each side of the surface of the E-shaped plate for fastening the two handles 6. Five countersunk connecting holes are machined on the top plate 5, one at the center of the rear side plate and two on each of the left and right side plates, distributed symmetrically, corresponding to the mounting base plate 1, with the countersunk holes facing upwards. Four limiting holes 9 are machined at the center of the left and right side plates and at the front end of the top plate 5, for connecting the top of the limiting rod 7, and their positions correspond to the mounting base plate 1.

[0028] like Figure 6 As shown, the handle 6 adopts a U-shaped structure and has a threaded hole at the connection with the top plate 5, which is convenient to be fastened to the top plate 5 with countersunk screws for manual or robot transportation. The surface is smooth and has a positioning boss, and anti-slip bumps are machined on the boss part, which facilitates manual transportation and picking, and also facilitates robot handling and positioning.

[0029] The conical positioning pins are set on the loading or unloading platforms corresponding to the preceding and following processes. The spacing is consistent with the positioning conical holes of the mounting base plate 1. The conical pins are arranged with the pins facing upwards, which facilitates quick installation and positioning with the transfer device.

[0030] The magnetic locking block is a strong magnetic block. The magnetic locking block is fastened to the groove on the lower surface of the mounting base plate 1 with countersunk screws 11. It can quickly connect with the suction structure set at the corresponding loading or unloading station, ensuring that the transfer device is fastened and does not move during the loading or unloading of the film 8.

[0031] The transfer device is assembled according to the layout shown in the figure. The fastening screws are passed through the elastic washers and the mounting base plate 1 and tightened to the connecting shaft 4. The support pad 3 is passed through the connecting shaft 4, and the tray 2 is passed through the five connecting shafts 4 respectively. The mounting support pad 3 and the tray 2 are alternately assembled on the connecting shaft 4. Finally, the top plate 5 is placed on the support pad 3 at the top and tightened with the fastening screws and elastic washers to the threaded hole at the other end of the connecting shaft 4. The two handles 6 are fastened to the top plate 5 with fastening screws to complete the assembly of the transfer device.

[0032] Before loading the film 8 into the transfer device, static electricity on the surface of the film 8 is removed by passing through the static removal area. The static removal device is installed below the film 8, including but not limited to the bottom, and can also be extended to the left and right sides of the film 8.

[0033] Install the limiting rods 7 on the left and right sides, load the film 8 into the transfer device in sequence, and then install the limiting rod 7 at the front end to limit the film 8 in the transfer device, thus ensuring that the film 8 does not slip during the transfer process.

[0034] By changing the external dimensions of the mounting base plate 1, the support plate 2, and the corresponding empty space dimensions of the connecting shaft 4, the loading and transfer of films 8 of different types and specifications can be accommodated. By changing the number of support plates 2 and support pads 3 and the length dimensions of the connecting shaft 4, the number of layers of film 8 can be increased or decreased. The successful development and application of this transfer device realizes the automatic docking of automated equipment in the preceding and following processes, eliminates the waste of manual handling of film 8 after cleaning, overcomes the misjudgment of the number of film 8 sheets by manual operation, improves the production efficiency and pass rate of strain gauges, reduces labor intensity, and reduces labor costs.
