DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] The utility model provides an ACF removal mechanism to solve the problem that the front end of the ACF is manually torn off in the prior art, the operation efficiency is low, the ACF may be contaminated by hands, and the contaminated ACF may have serious malfunction when used.

[0030] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 2An ACF removal mechanism in an embodiment of the present application includes an upper mold assembly 1, a transmission assembly 2, a lower mold assembly 3 and an adsorption assembly 4; the upper mold assembly 1 includes an upper mold head 11 which is liftable and arranged in an upper mold base 10 and has an adjustable temperature; the transmission assembly 2 is arranged on one side of the upper mold assembly 1, and is used to transfer the ACF5 attached to the scrap belt from the bottom of the upper mold head 11 to the front; the lower mold assembly 3 is arranged below the upper mold assembly 1, and the lower mold assembly 3 includes a lower mold base 30 and a lower mold head 31 arranged on the lower mold base; the adsorption assembly 4 is detachably arranged on the lower mold base 30, and the adsorption assembly 4 has an adsorption surface 310 extending to the upper surface of the lower mold head 31.

[0031] The ACF removal mechanism of the utility model, when the upper die head 11 is heated up and drives the ACF5 attached to the waste belt in the transmission component 2 to move down to the adsorption surface, the ACF with the front end cut off is attached to the adsorption surface 310. Since the temperature of the upper die head 11 is relatively high and the adsorption surface is at room temperature, the cut ACF8 is easily adsorbed on the adsorption surface 310, thereby realizing automatic tearing of the cut front end of the ACF. The operation is convenient and simple, manual operation is avoided, and it is ensured that the ACF will not be contaminated during use, thereby reducing the risk of adverse effects caused by product contamination.

[0032] based on Figure 1 In this embodiment, the transmission component 2 includes a feed reel 20 arranged on the left side of the upper mold component 1, and two feed rollers 21 for relative transmission are provided below the upper mold head 11. The two feed rollers 21 are relatively arranged on the upper mold base, and a limiting groove for limiting ACF is provided on the feed rollers 21.

[0033] During operation, the ACF5 attached to the scrap belt is fed out by the feed reel 20, and then continues to be transported forward after being limited by the two feed rollers 21. The two feed rollers 21 assist in the forward transport of the ACF5 attached to the scrap belt, and enable the ACF5 attached to the scrap belt to be just below the upper die head 11. In this way, when the upper die head 11 descends, the ACF5 attached to the scrap belt can be driven to move downward until the ACF8 is adsorbed on the adsorption surface 310.

[0034] based on Figure 2 and Figure 4In this embodiment, the adsorption assembly 4 includes an L-shaped support plate 40, a protruding block 41, a locking screw 42, a pressure plate 43 and a bearing plate 44; the L-shaped support plate 40 is detachably arranged on one side of the lower die base 30 through a quick release mechanism; the protruding block 41 is arranged on the upper surface of the L-shaped support plate 40, and the two ends of the protruding block are aligned along the two ends of the L-shaped support plate 40; the cross-section of the pressure plate 43 is inclined, one end of the pressure plate 43 is arranged on the protruding block 41 through a locking screw 42, and the other end extends outward to the top of the L-shaped support plate 40, and a clamping gap is left between the pressure plate 43 and the L-shaped support plate 50; the bearing plate 44 is clamped in the clamping gap through the pressure plate 43, and one end of the bearing plate 44 extends from the clamping gap to the upper surface of the lower die head 31, and the bearing plate has an adsorption surface 310.

[0035] During operation, first quickly install the pressing plate 43 on the raised block 41 through the two locking screws 42, and do not lock the pressing plate 43 first. Then insert the supporting plate 44 into the clamping gap between the pressing plate 43 and the L-shaped supporting plate 40, and make the adsorption surface 310 on the supporting plate 44 just located on the upper surface of the lower die head 31, and finally lock the locking screws 42. Since the cross-section of the pressing plate 43 is inclined, the supporting plate 44 can be pressed against the L-shaped supporting plate by locking the pressing plate 43, thereby realizing the installation and fixation of the adsorption surface, and the operation is convenient and effective.

[0036] At the same time, since the carrying plate 44 is detachably installed, the carrying plate can be easily cleaned and replaced, and can be used repeatedly, ensuring that the ACF left in the device is free of any contamination.

[0037] In addition, the material of the support plate 44 is a high temperature resistant resin, which can avoid damage due to high temperature after the upper die head is pressed down and contacted with the high temperature, thereby improving the service life.

[0038] Furthermore, the quick-release mechanism in this embodiment includes at least one magnet 60, and the L-shaped support plate is set to a material that can be adsorbed by the magnet 60; during installation, one side of the L-shaped support plate can be adsorbed and fixed by the magnet, and at the same time, a positioning pin 61 is provided on the lower mold base 30 and is arranged on the same side as the magnet 60 for positioning the L-shaped support plate, so that the L-shaped support plate can be quickly fixed and limited.

[0039] Furthermore, in this embodiment, the number of the magnets 60 can also be set to two, and the two magnets are relatively arranged on the side of the lower mold base opposite to the adsorption component, so that the L-shaped support plate can be adsorbed and fixed more securely.

[0040] In addition, in this embodiment, the upper die head 11 has a heat-conducting wire for heating, so that the upper die head 11 can be heated conveniently. In this way, when the ACF attached to the scrap tape moves down to the adsorption surface, since the upper die head contacts the ACF after heating, and the adsorption surface 310 is at room temperature, the ACF can quickly detach from the scrap tape and attach to the adsorption surface. When the scrap tape and the upper die head 11 return to their original positions, the cut ACF is separated from the scrap tape.

[0041] based on Figures 1 to 4 The specific workflow is as follows:

[0042] In the actual operation process, the front end of the ACF needs to be cut off by a shearing device, but at this time the ACF is still attached to the waste belt.

[0043] After the ACF at the front end is cut off, the mechanism is quickly installed on the lower die base so that the adsorption surface is located on the upper surface of the lower die head, and then the ACF is transmitted forward through the feed tray and two feed rollers. When the cut ACF moves above the set adsorption surface, the upper die head heats up and drives the ACF attached to the waste belt to move downward to the adsorption surface. Since the adsorption surface is at room temperature, the ACF will easily detach from the waste belt and be adsorbed on the adsorption surface. Then the upper die head drives the waste belt back to its position, thereby leaving the cut ACF on the adsorption surface, thereby realizing the tearing of the ACF without manual contact.

[0044] Finally, the mechanism is quickly disassembled from the lower die base, and then the product is placed on the lower die head to produce the corresponding actual product.

[0045] In summary, during the entire operation process, personnel do not need to touch the ACF part, avoiding human contamination caused by personnel touching the ACF surface during the ACF removal process, and reducing the risk of adverse products caused by contamination.

[0046] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
