Description

Technical Field

[0001] The present invention relates to the technical field of film laminating machines, and more specifically, it particularly designs a semi-automatic double-sided film laminating machine for the surface of the tweezer tips of tweezers. Background Art

[0002] Tweezers are a tool used to pick up bulk drugs, metal particles, hair, fine thorns and other small things. The tweezer tips of tweezers are relatively small and sharp. Applying a film can prevent the surface of the tweezer tips from oxidation and scratches, ensure the surface beauty of the tweezer tips, prevent the tweezer tips from stabbing users, and also avoid damaging the tweezer tips during packaging and transportation, which affects the product sales.

[0003] Surface beauty.

[0004] Basically, the tweezer tips of the tweezers sold on the market are not film laminated. Usually, a transparent soft plastic sleeve is put on the tweezer tips to protect the tweezer tips from scratching. The cost of the soft plastic sleeve is relatively high. Protecting the tweezer tips of tweezers by applying a film can reduce the cost.

[0005] At present, there are many types of film laminating machines on the market, and basically they are all specially designed for specific workpieces. There is no film laminating machine dedicated to film laminating for tweezers. It is very necessary to design a film laminating machine that can efficiently film laminate the two tweezer tips of tweezers at the same time. Summary of the Invention

[0006] The invention purpose of the present invention is to solve the above-mentioned existing technical problems, and aims to provide a semi-automatic double-sided film laminating machine for the surface of the tweezer tips of tweezers, which can quickly perform double-sided film lamination on the surface of tweezers and improve the film lamination efficiency.

[0007] The present invention is realized through the following technical solutions.

[0008] The present invention provides a semi-automatic double-sided film laminating machine for the surface of the tweezer tips of tweezers, which includes:

[0009] A frame and a tape wheel assembly, a guide wheel assembly, a pressing die wheel assembly and a tweezer fixture arranged on the frame;

[0010] The tape wheel assembly includes an upper tape wheel assembly and a lower tape wheel assembly. The number of the upper tape wheel assemblies is two groups, and the two groups of upper tape wheel assemblies are symmetrically arranged left and right. The lower tape wheel assembly is arranged below the upper tape wheel assembly. The number of the lower tape wheel assemblies is two groups, and the two groups of lower tape wheel assemblies are symmetrically arranged left and right;

[0011] The guide wheel assembly includes an upper guide wheel assembly and a lower guide wheel assembly. There are two sets of upper guide wheel assemblies, and the two sets of upper guide wheel assemblies are symmetrically arranged left and right. There are two sets of lower guide wheel assemblies, and the two sets of lower guide wheel assemblies are symmetrically arranged left and right. The left lower guide wheel assembly is located at a position slightly to the left below the left upper guide wheel assembly, and the right lower guide wheel assembly is located at a position slightly to the right below the right upper guide wheel assembly. The upper guide wheel assembly cooperates with the upper tape wheel assembly to guide the tape, and the lower guide wheel assembly cooperates with the lower guide wheel assembly to guide the tape;

[0012] There are two sets of film pressing wheel assemblies, and the two sets of film pressing wheel assemblies are symmetrically arranged left and right. The film pressing wheel assembly includes a film pressing wheel, a driving motor, a sliding device and a pressing mechanism. The sliding device can slide left and right. The pressing device provides a pressing force for the two sliding devices to approach each other. The driving motor is fixed on the sliding device, and the film pressing wheel is connected to the output shaft of the driving motor;

[0013] The tweezer clamp includes a tweezer limiting member and a tweezer positioning member. On the side of the tweezer limiting member facing the film pressing wheel, there is a vertically penetrating limiting groove for placing the tweezers. The limiting groove is aligned with the position between the left and right film pressing wheels. The tweezer positioning member is arranged to be able to move left and right. When the tweezer positioning member moves to the stationary position to the right, the tweezer positioning member can block the tweezer from moving downward along the limiting groove. When the tweezer positioning member moves to the stationary position to the left, the tweezer can move downward along the limiting groove.

[0014] In the above technical solution, four loop-shaped tapes can be installed through two sets of upper tape wheel assemblies and two sets of lower tape wheel assemblies. Among them, the tapes of the two loop-shaped tapes installed by the two sets of upper tape wheel assemblies pass downward through the positions between the two film pressing wheels after being guided by the two sets of upper guide wheel assemblies. The tapes of the two loop-shaped tapes installed by the two sets of lower tape wheel assemblies also pass downward through the positions between the two film pressing wheels after being guided by the two sets of lower guide wheel assemblies. At the same time, because the upper guide wheel assembly and the lower guide wheel assembly are not on the same vertical line in the vertical direction, the tapes passing through the upper guide wheel assembly and the tapes passing through the lower guide wheel assembly do not overlap before passing through the positions between the two film pressing wheels, and there is a space for placing the tip of the forceps. When applying the film, the tail of the forceps is placed in the limiting groove of the forceps limiting member. The forceps positioning member moves to the right across the limiting groove and supports the forceps under the forceps. The two tips of the forceps are respectively placed between the two tapes on the left and the two tapes on the right. The film pressing wheel rotates driven by the driving motor. At the same time, the forceps positioning member moves to the left to allow the forceps to move downward along the limiting groove. The film pressing wheel drives the tape and the forceps to move downward. When the two tips of the forceps and the tape pass through the two film pressing wheels, the tape can be applied to the inner and outer sides of the tip of the forceps. Then, after the forceps positioning member moves to the right in place under the control of the control system, a new pair of forceps is placed in the limiting groove of the forceps limiting member and the cyclic operation can be carried out to apply the film to the tips of the new pair of forceps. This technical solution can apply the film to the two tips of the forceps, with high processing efficiency, and no bubbles will be generated during film application, and the film application effect is good.

[0015] Preferably, the sliding device includes a bottom plate, a slider and a guide rail. The driving motor is fixed to the rear side of the bottom plate. The output shaft of the driving motor extends to the front side of the bottom plate and is connected to the film pressing wheel. The bottom plate is slidably connected to the guide rail through the slider fixed to the rear side of the bottom plate. The guide rail is horizontally arranged left and right and fixed to the frame. The guide rail includes an upper guide rail and a lower guide rail. The upper guide rail and the lower guide rail are arranged parallel to each other at an upper and lower interval. In this technical solution, the bottom plate of the sliding device slides along the two tracks, the sliding process is stable, the occurrence of vibration is avoided, and the noise generated during operation is very small, providing a more comfortable and quiet operating environment for the user.

[0016] Preferably, the pressing mechanism includes a smooth shaft and a compression spring sleeved on the smooth shaft. The smooth shaft is horizontally arranged left and right. One end of the smooth shaft is fixedly connected to the frame. A connecting plate is provided on the side surface of the bottom plate. The other end of the smooth shaft passes through a guiding and sliding hole provided in the connecting plate and is slidably connected to the connecting plate. One end of the compression spring abuts against the frame, and the other end abuts against the connecting plate. In this technical solution, the connecting plate of the sliding device is tightly abutted against the compression spring, ensuring that the compression spring can always provide a continuous pressing force for the two groups of sliding devices. This design enables the tape to be tightly attached to the inner and outer surfaces of the forceps head during the process of the film pressing wheel laminating the tape on the inner and outer surfaces of the forceps head, effectively avoiding the generation of air bubbles. Such a tight attachment not only improves the efficiency of film lamination but also ensures a perfect film lamination effect, providing a reliable guarantee for subsequent use.

[0017] Preferably, both the upper tape wheel assembly and the lower tape wheel assembly include a tape wheel, a bolt, a baffle, a guiding and sliding shaft, and a mounting seat. The circumferential surface of the front half of the bolt is smooth, and the circumferential surface of the rear half is provided with threads. The tape wheel is sleeved on the smooth surface position of the bolt. The bolt passes through the baffle and is threadedly connected to the mounting seat, and a nut is screwed on the rear side of the baffle. The guiding and sliding shaft is slidably connected to the mounting seat, and the front end of the guiding and sliding shaft is fixedly connected to the baffle. In this technical solution, the precise adjustment of the front and rear positions of the tape wheel is achieved by screwing the bolt. This adjustment mechanism allows the operator to finely move the tape wheel back and forth as needed, ensuring that the edges of all tapes can be perfectly aligned. When the edges of the tapes are aligned, the operator can ensure that the tapes on the inner and outer surfaces of the forceps head are completely aligned during the film lamination operation using the forceps head, thus achieving an ideal attachment effect. The accuracy of this alignment not only improves the efficiency of the film lamination operation but also significantly enhances the quality of the final product, ensuring the flatness and aesthetics of the film lamination.

[0018] Preferably, two grooves are provided on the circumferential surface of the tape wheel. The two grooves are radially symmetrical, and tape clamping elastic pieces are provided in the grooves. In this technical solution, the ring-shaped tape can be easily installed on the tape wheel. When the ring-shaped tape is sleeved in place, the clamping elastic pieces will automatically come into play and tightly fix the ring-shaped tape on the tape wheel. This design greatly simplifies the process of replacing the ring-shaped tape, making it convenient and fast. In addition, it effectively prevents any impact that may be caused by the accidental detachment of the ring-shaped tape during the film lamination process, ensuring the smooth progress of the film lamination operation.

[0019] Preferably, a ring-shaped rib with a diameter larger than that of the tape wheel is provided at the rear side of the tape wheel, and the ring-shaped rib is coaxially arranged with the tape wheel. In this technical solution, the purpose of the ring-shaped rib design is to effectively block and limit the ring-shaped tape sleeved on the tape wheel. This design ensures that during operations, such as turning a bolt to adjust the front and rear position of the tape wheel, the edge of the tape wheel can be precisely aligned. At the same time, the ring-shaped rib also ensures that the edge of the ring-shaped tape sleeved on the tape wheel can also remain aligned, thus guaranteeing the accuracy and reliability of the entire device.

[0020] Preferably, the mounting seat of the lower tape wheel assembly is fixedly connected to the connecting plate, and the lower guide wheel assembly is arranged on the front side of the bottom plate and connected to the bottom plate. In this way, the lower tape wheel assembly, the lower guide wheel assembly, and the film pressing wheel can synchronously move left and right along with the sliding device. When the left and right film pressing wheels approach or open up to each other, the tape will not displace relative to the surface of the film pressing wheel during the process of passing over the surface of the film pressing wheel. Such a design can effectively prevent the situation where the tape does not fully adhere to the surface of the film pressing wheel when in contact with it, thus avoiding the problem of bubbles easily generated due to tape displacement.

[0021] Preferably, the tweezer positioning member is an electromagnetic push rod. The main body of the electromagnetic push rod is fixedly connected to the tweezer limiting member, and the rod body of the electromagnetic push rod can move back and forth in the left-right direction. In this technical solution, the electromagnetic push rod has the significant advantage of a fast response speed. It can quickly switch between two different working states, namely the state of blocking the tweezer from moving downward along the limiting groove and the state of allowing the tweezer to move downward along the limiting groove. Through this fast switching mechanism, the electromagnetic push rod ensures that during the continuous production process, the film pasting operation of the previous tweezer and the film pasting operation of the next tweezer can be seamlessly connected, thus greatly improving the efficiency and continuity of the entire film pasting process.

[0022] Preferably, a cutter assembly for cutting the tape is provided below the film pressing wheel assembly. The number of the cutter assemblies is two groups, and the two groups of cutter assemblies are symmetrically arranged left and right and can approach each other. In this technical solution, through parameter settings, the user can flexibly perform precise single-tweezer film pasting cutting operations on the tweezers that have completed the film pasting process, or select to cut the film pasting of several tweezers as a whole, thereby realizing automated processing, reducing the need for traditional manual operations, greatly improving the overall work efficiency, while reducing the labor intensity and ensuring the high efficiency and stability of the production process.

[0023] Preferably, the cutter assembly includes a cutter, a mounting bracket, a cutter slider, and a pusher. The cutter is mounted on the mounting bracket, the mounting bracket is fixedly connected to the cutter slider, the cutter slider is slidably connected to the lower guide rail, and the pusher is fixed to the machine frame and can push the mounting bracket to slide left and right along the lower guide rail. In this technical solution, by pushing the mounting bracket with the pusher, the mounting bracket can slide smoothly along the lower guide rail. This sliding mechanism enables the cutter to precisely cut the tape, thereby greatly improving the automation level of the entire processing process and ensuring the efficiency and accuracy of the operation.

[0024] The beneficial effect of the present invention is that during the production process, workers manually place the tweezers on the tweezer fixture. Once this action is completed, simply by activating the control switch, the double-sided film pasting work on the surface of the tweezer tips can be quickly completed. By continuously repeating this process, that is, continuously placing the tweezers in the tweezer fixture and activating the control switch, continuous tweezer film pasting operations can be achieved. This method significantly improves the efficiency of film pasting on the tweezer tips, greatly enhancing the automation level of the entire production process. At the same time, this efficient film pasting method also effectively reduces the cost of film pasting on the tweezer tips, thereby enhancing the market competitiveness of the product.

[0036] The technical solutions of the present invention will be further specifically described below through specific embodiments in conjunction with the drawings:

[0037] Embodiment 1

The two cross plates 13 are arranged vertically and parallel to each other at intervals.

[0039] As Figure 1 , in this embodiment, the tape wheel assembly includes an upper tape wheel assembly 2 and a lower tape wheel assembly 3. The number of the upper tape wheel assemblies 2 is two groups, and the two groups of upper tape wheel assemblies 2 are symmetrically arranged left and right and are fixedly connected to the upper cross plate 13. The lower tape wheel assembly 3 is arranged below the upper tape wheel assembly 2. The number of the lower tape wheel assemblies 3 is two groups, and the two groups of lower tape wheel assemblies 3 are symmetrically arranged left and right.

[0040] As a further improvement, as Figure 5 and Figure 6As shown, the upper tape wheel assembly 2 and the lower tape wheel assembly 3 both include a tape wheel 21, a bolt 22, a baffle 23, a guide shaft 24, and a mounting seat 25. The circumferential surface of the front half of the bolt 22 is smooth, and the circumferential surface of the rear half is provided with threads. The tape wheel 21 is sleeved on the smooth surface position of the bolt 22 through a bearing 27. The bolt 22 passes through the baffle 23 and is threadedly connected to the mounting seat 25, and a nut 26 is screwed on the rear side of the baffle 23.

A ring-shaped edge 212 with a diameter larger than that of the tape wheel 21 is provided at the rear side of the tape wheel 21. The ring-shaped edge 212 is coaxially arranged with the tape wheel. The purpose of the design of the ring-shaped edge 212 is to effectively block and limit the ring-shaped tape 10 sleeved on the tape wheel 21, so that the edges of the ring-shaped tape 10 can be accurately aligned.

[0041] As Figure 1 shown, in this embodiment, the guide wheel assembly includes an upper guide wheel assembly 4 and a lower guide wheel assembly 5. The number of the upper guide wheel assemblies 4 is two groups. The two groups of upper guide wheel assemblies 4 are symmetrically arranged left and right and are fixedly connected to the upper cross plate 13. The number of the lower guide wheel assemblies 5 is two groups. The two groups of lower guide wheel assemblies 5 are symmetrically arranged left and right. The left lower guide wheel assembly 5 is located at a position slightly to the left below the left upper guide wheel assembly 4, and the right lower guide wheel assembly 5 is located at a position slightly to the right below the right upper guide wheel assembly 4. The upper guide wheel assembly 4 and the upper tape wheel assembly 2 cooperate to guide the tape 10, and the lower guide wheel assembly 3 and the lower guide wheel assembly 5 cooperate to guide the tape 10;

[0042] As Figure 1 shown, in this embodiment, the number of the film pressing wheel assemblies 6 is two groups. The two groups of film pressing wheel assemblies 6 are symmetrically arranged left and right. The film pressing wheel assembly 6 includes a film pressing wheel 61, a driving motor 62, a sliding device, and a pressing mechanism. The sliding device can slide left and right. The pressing device provides a pressing force for the two sliding devices to approach each other. The driving motor 62 is fixed on the sliding device, and the film pressing wheel 61 is connected to the output shaft of the driving motor 62.

[0043] As a further improvement, as Figure 1 and Figure 4As shown, in this embodiment, the sliding device includes a bottom plate 63, a slider 64, and a guide rail. The driving motor 62 is fixed to the rear side of the bottom plate 63. The output shaft of the driving motor 62 extends to the front side of the bottom plate 63 and is connected to the film pressing wheel 61. The bottom plate 63 is slidably connected to the guide rail through the slider 64 fixed to the rear side of the bottom plate 63. The guide rail is horizontally arranged left and right and fixed to the frame 1. Among them, the guide rail includes an upper guide rail 651 and a lower guide rail 652. The upper guide rail 651 and the lower guide rail 652 are arranged parallel to each other at an upper and lower interval. Specifically, the upper guide rail 651 is fixed to the lower edge position of the upper cross plate 13, and the lower guide rail 652 is fixed to the upper edge position of the lower cross plate 13.

[0044] As Figure 3 and Figure 4 shown, in this embodiment, the pressing mechanism includes a light shaft 66 and a compression spring 67 sleeved on the light shaft 66. The light shaft 66 is horizontally arranged left and right. One end of the light shaft 66 is fixedly connected to the column 12 of the frame 1. A connecting plate 631 is provided on the side surface of the bottom plate 63. The other end of the light shaft 66 passes through the guiding hole provided in the connecting plate 631 and is slidably connected to the connecting plate 631. In order to make the sliding smoother, a bushing is provided in the guiding hole for the light shaft 66 to pass through. One end of the compression spring 67 abuts against the column 12, and the other end abuts against the connecting plate 631.

[0045] As Figure 7As shown, in this embodiment, the tweezer fixture 7 is disposed at the position directly in front between the two film pressing wheels 61 and is fixedly connected to the cross plate 13 below the frame 1 through the connecting bracket 73. It includes a tweezer limiting member 71 and a tweezer positioning member 72. On the side of the tweezer limiting member 71 facing the film pressing wheel 61, there is a vertically penetrating limiting groove 711 for placing the tweezer 8. The limiting groove 711 is aligned with the position between the left and right film pressing wheels 61. The tweezer positioning member 72 is arranged to be movable left and right. When the tweezer positioning member 72 moves to the right to the stationary position, the tweezer positioning member 72 can block the tweezer 8 from moving downward along the limiting groove 711. When the tweezer positioning member 72 moves to the left to the stationary position, the tweezer 8 can move downward along the limiting groove 711. In order to achieve the above technical effects, in this embodiment, the tweezer positioning member 72 selects an electromagnetic push rod. The main body of the electromagnetic push rod is disposed on the side of the tweezer limiting member 71 close to the film pressing wheel 61 and is fixedly connected to the tweezer limiting member 71. The rod body 721 of the electromagnetic push rod can move back and forth in the left and right directions to block the tweezer 8 from moving downward along the limiting groove 711 on the side of the limiting groove 711 close to the film pressing wheel 61, or allow the tweezer 8 to move downward along the limiting groove 711. The electromagnetic push rod has the significant advantage of fast response speed. It can quickly switch between two different working states, which are the state of blocking the tweezer 8 from moving downward along the limiting groove 711 and the state of allowing the tweezer 8 to move downward along the limiting groove 711. Through this fast switching mechanism, the electromagnetic push rod ensures that in the continuous production process, the film pasting operation of the previous tweezer 8 and the film pasting operation of the next tweezer 8 can be seamlessly connected, thus greatly improving the efficiency and continuity of the entire film pasting process.

[0046] The working principle of the present invention is as follows:

[0047] As Figure 1 and Figure 2 shown, when performing film pasting, the tail of the tweezer 8 is placed in the limiting groove 711 of the tweezer limiting member 71. The rod body 721 of the electromagnetic push rod moves to the right across the limiting groove 711 to support the tweezer 8 below. The two tweezer heads of the tweezer 8 are respectively placed between the two tapes 10 on the left and the two tapes 10 on the right. The film pressing wheel 61 rotates under the drive of the drive motor 62. At the same time, the rod body 721 of the electromagnetic push rod moves to the left to allow the tweezer 8 to move downward along the limiting groove. The film pressing wheel 61 drives the tape 10 and the tweezer 8 to move downward. When the two tweezer heads of the tweezer 8 and the tape 10 pass through the two film pressing wheels 61, the thickness of the tweezer head will force the two film pressing wheels 61 to move away from each other by a certain distance. At this time, the pressing mechanism provides a pressing force for the two film pressing wheels 61 to approach to firmly paste the tape 10 on the inner and outer sides of the tweezer head. Then, after the rod body 721 of the electromagnetic push rod moves to the right in place under the control of the control system, a new tweezer 8 is placed in the limiting groove 711 of the tweezer limiting member 71 and the cycle operation can complete the film pasting of the tweezer head of the new tweezer 8.

[0048] Example 2

[0049] The structure of this embodiment is similar to that of Embodiment 1, except that, as Figure 8 and Figure 9 shown, the mounting seat 25 of the lower tape pulley assembly 3 is fixedly connected to the connecting plate 631, and the lower guide wheel assembly 6 is arranged on the front side of the bottom plate 63 and connected to the bottom plate 63.

[0050] In this embodiment, the lower tape pulley assembly 3, the lower guide wheel assembly 5, and the film pressing wheel 61 can synchronously move left and right along with the sliding device. When the two left and right film pressing wheels 61 approach or open up to each other, during the process of the tape 10 passing through the surface of the film pressing wheel 61, there will be no displacement relative to the surface of the film pressing wheel 61. Such a design can effectively prevent the situation that the tape 10 is not fully attached when contacting the surface of the film pressing wheel 61, thereby avoiding the problem of bubbles easily generated due to the displacement of the tape 10.

[0051] Example 3

[0052] The structure of this embodiment is similar to that of Embodiment 2, except that, as Figure 1 and Figure 10 shown, a cutter assembly 9 for cutting the tape 10 is provided below the film pressing wheel assembly 6. The number of the cutter assemblies 9 is two groups. The two groups of cutter assemblies 9 are symmetrically arranged left and right and can approach each other.

[0053] In this embodiment, the cutter assembly 9 includes a cutter 91, a mounting frame 92, a cutter slider 93, and a pushing member 94. The cutter 91 is installed on the mounting frame 92. The mounting frame 92 is fixedly connected to the cutter slider 93. The cutter slider 93 is slidably connected to the lower guide rail 652. The pushing member 94 is fixed on the cross plate 13 below the frame 1 and can push the mounting frame 92 to slide left and right along the lower guide rail 652. In this embodiment, the pushing member 94 is selected as an electromagnetic push rod. The electromagnetic push rod has the significant advantage of fast response speed. By pushing the mounting frame 92 with the electromagnetic push rod, the cutter 91 can quickly and accurately cut the tape 10, thereby greatly improving the automation level of the entire processing process and ensuring the efficiency and accuracy of the operation.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
