Description

Technical Field

[0001] The invention relates to the field of mobile phone foam cutting equipment, and in particular to a laminating and cutting equipment for foam processing. Background Art

[0002] The foam of the back cover of the mobile phone is used to separate the mobile phone battery and the back cover, and plays a shock-absorbing and protective role for the mobile phone. It is usually produced by a stamping and die-cutting process, that is, the foam raw material is cut using a mold blade and stamping equipment to obtain a foam die-cut part of the required shape and size.

[0003] At present, in the stamping of the foam of the back cover of the mobile phone, the foam raw material is composed of an upper foam layer and a lower carrier layer adhered together. When the foam raw material is pulled and transported into the punching mechanism, the foam layer is punched into a desired shape by a die-cutting tool, and then the waste of the foam layer is separated from the carrier layer by rolling, and the formed foam die-cut parts are transported out with the carrier layer. This process not only promotes the smoothness of the production line, but also ensures the centralized recycling and treatment of the foam waste. However, in order to ensure the efficiency of rolling up the foam layer waste, a certain width of excess material is generally reserved on both sides of the foam raw material in the prior art. These "residues" connect the punched foam waste of each part like a bridge, so that the foam waste and the carrier layer can be smoothly peeled off and the foam waste can be rolled up during the rolling process, but it also causes waste of foam raw materials and increases production costs.

[0004] Therefore, we have made improvements to this and proposed a laminating and cutting device for foam processing. Summary of the invention

[0042] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] The present invention will be further described below in conjunction with the embodiments.

[0044] Example 1: Reference Figure 1 A foam processing laminating and cutting device includes a die-cutting machine 100 and a foam raw material 200. The die-cutting machine 100 is equipped with a punching mechanism 101 for die-cutting the foam raw material 200. The foam raw material 200 is punched and formed when it is pulled through the punching mechanism 101 by an external traction mechanism. This is an existing mature technology and is not detailed here.

[0045] In order to solve the problem that the waste is discharged by winding in the prior art, which causes waste of the foam raw material 200 and increases the production cost, in this embodiment, the tool holder 102 and the waste discharge method are improved. Specifically, refer to Figures 1 to 5 , comprising a tool holder 102 mounted on a punching mechanism 101, the bottom end of the tool holder 102 having a die-cutting blade 103 corresponding to the desired foam shape and a cutting blade 104 for cutting off the upper layer of the foam raw material 200;

[0046] It also includes a rotating seat 300 intermittently rotatably installed on one side of the punching mechanism 101, and a plurality of groups of needle claw seats 301 are equidistantly installed on the rotating seat 300 in a ring shape. Preferably, in the present embodiment, there are two groups of needle claw seats 301, and correspondingly, the rotating seat 300 rotates at an angle of 180° each time, and the two groups of needle claw seats 301 are symmetrical about the central axis of the rotating seat 300. The number of needle claw seats 301 in each group is five, and each group of needle claw seats 301 is used to grab an independent one after being die-cut and cut off. A group of crochet needles 3011 extending outward by pneumatic drive is movably arranged on the needle claw seat 301, and a first air pipe 3012 is provided at the end of the needle claw seat 301, and the first air pipe 3012 is connected to an external air source through a first pneumatic rotary joint assembly 500 installed at the end of the rotating seat 300;

[0047] In the specific implementation process, when the foam raw material 200 is punched, it will be cut into independent parts by the cutting blade 104, and then when it is pulled forward, the rotating seat 300 rotates synchronously, and the rotation speed corresponds to the speed at which the foam raw material 200 is pulled forward. In this process, the hook needle 3011 on each needle claw seat 301 enters the foam waste when it is tangent to the foam raw material 200 and hooks it, and then uses the relative movement of the rotation of the rotating seat 300 and the advancement of the foam to separate the foam waste from the foam raw material 200, thereby achieving the purpose of separating the foam waste, thereby reducing the "surplus material" on both sides of the foam raw material 200 and saving the cost of raw materials (refer to Figure 8 As shown in the figure, it shows a schematic diagram of the layout of the two types of foam raw materials 200 that are discharged in the original winding method and the waste discharge in the present application). At the same time, the self-rotation movement of the rotating seat 300 is synchronized with the forward traction movement of the foam raw material 200 after being punched and cut. The rotating seat 300 performs a cyclical rotation movement, which ensures the production efficiency and waste collection efficiency of the foam on the back cover of the mobile phone.

[0048] Further, such as Figure 3 As shown in the figure, the die-cutting blade 103 is provided with two groups, and the cutting blade 104 is located in the middle of the die-cutting blade 103 in the forward direction of the foam raw material 200. The place where the upper layer of the foam raw material 200 is cut off is the starting point where the hook needle 3011 on the needle claw seat 301 begins to pierce the upper layer of the foam raw material 200. The purpose of this design is to make the hook needle 3011 hook the thicker part of the foam waste when peeling the foam waste, so as to facilitate its complete and smooth peeling, and avoid the foam waste at the starting point of the peeling being narrow and easy to be pulled off;

[0049] Further, such as Figure 7 As shown in the figure, the inner end of the needle claw seat 301 has a linear airway 3013, the first air pipe 3012 is located at one end of the needle claw seat 301 and is connected to the linear airway 3013, the outer end of the needle claw seat 301 has a group of piston channels 3014 connected to the linear airway 3013, the inner end of the hook needle 3011 is located in the piston channel 3014 and is fixed with a matching piston block 3015, and a return spring 3016 is also fixed between the piston block 3015 and the inner wall of the piston channel 3014, and the corresponding linear airway 3013 is supplied to the corresponding linear airway 3013 through the first pneumatic rotary joint assembly 500. When the channel 3013 is inflated, correspondingly, all the crochet needles 3011 on the needle claw seat 301 will move outward, and the outward moving distance is the distance between the bottom end of the crochet needle 3011 and the carrier layer of the foam raw material 200 when the crochet needle 3011 is located directly above the foam, that is, the crochet needle 3011 can penetrate into the upper foam layer; it is driven pneumatically, so that it is convenient to use the first pneumatic rotary joint assembly 500 to drive the crochet needle 3011 to work. At the same time, when the waste is discharged, the air is released, and the reset spring 3016 resets the crochet needle 3011, that is, the restriction on the foam waste disappears, which facilitates the discharge of the foam waste.

[0050] It can be explained that the position of the hook needle 3011 on each needle claw seat 301 in a group of needle claw seats 301 corresponds to the position of the foam waste when it passes the lowest point of the rotating seat 300. For ease of understanding, please refer to Figure 4 The rotating seat 300 has a portion corresponding to the shape of the required mobile phone foam, and the corresponding spare portion is the portion where the crochet hook 3011 is located. Preferably, the crochet hooks 3011 on each needle claw seat 301 can be arranged crosswise to improve the stability of hooking the foam waste.

[0051] Further, such as Figure 7 As shown in the figure, the side of the rotating seat 300 has a group of fixed seats 303 for the needle claw seat 301 to be embedded and installed, the fixed seat 303 is provided with an installation groove adapted to the needle claw seat 301, and the end of the fixed seat 303 is provided with a first air supply duct 304 for the first air pipe 3012 to be sealed and inserted into the connection, and the other port of the first air supply duct 304 is located at the side end of the rotating seat 300, and the fixed seat 303 and the needle claw seat 301 are respectively provided with first installation holes 305 for fastener fixation, and the fixed seat 303 is provided to facilitate the disassembly and assembly of the needle claw seat 301, and the first air supply duct 304 is provided to facilitate its connection with the first pneumatic rotary joint assembly 500, so that it drives the crochet needle 3011 to work.

[0052] Further, such as Figure 5 As shown in the figure, a pair of matching shells 306 are also installed at the outer end of the rotating seat 300. The shell 306 is provided with a movable slot 311 corresponding to the needle claw seat 301, so that the hook needle can extend into the foam waste. The two ends of the shell 306 respectively have arc-shaped protrusions matching the side ends of the rotating seat 300. The arc-shaped protrusions and the ends of the rotating seat 300 are respectively provided with second mounting holes 307 for installing fasteners, which facilitates the installation of the shell 306.

[0053] Further, such as Figure 1 , Figure 4 and Figure 5As shown in the figure, both ends of the rotating seat 300 have a hollow rotating shaft 302, and the outer port of the first air supply channel 304 is located in the rotating shaft 302. The first pneumatic rotary joint assembly 500 includes a rotor part 502 installed inside the rotating shaft 302 and a stator part 501 fixed on the die-cutting machine 100 and adapted to the rotor part 502. The stator part 501 is fixed on the die-cutting machine 100 through a corresponding mounting seat. The end of the rotor part 502 has a second air pipe 5021 adapted to the first air supply channel 304. The second air pipe 5021 is inserted into the port of the first air supply channel 304 to achieve ventilation and communication with the corresponding needle claw seat 301. The structural components of the first pneumatic rotary joint assembly 500 are similar to the "pneumatic slip ring" in the prior art. A plurality of air inlets are arranged on the stator part 501. Through each air inlet, the corresponding needle claw seat 301 in rotation can be inflated and deflated to achieve the driving extension and retraction of the crochet needle 301.

[0054] Embodiment 2: Based on the above embodiment, this embodiment further adds a method for discharging the foam waste after peeling;

[0055] Specifically, Figure 1 , Figure 2 , Figures 4 to 6 As shown in , the rotating seat 300 is also embedded with a plurality of groups of air nozzles 308 for blowing off foam waste, and the shell 306 is provided with corresponding air holes 310 corresponding to the air nozzles 308. The end of the rotating seat 300 is provided with a second air supply channel 309 adapted to communicate with the air nozzles 308, and the second air supply channel 309 is connected to an external air source through a second pneumatic rotary joint assembly 600; wherein the structure of the second pneumatic rotary joint assembly 600 is the same as that of the first pneumatic rotary joint assembly 500, and the number of its air inlets corresponds to the number of the air nozzles 308. Preferably, in the present embodiment, two groups of air nozzles 308 are provided, and each group has four, wherein every two air nozzles 308 are arranged linearly, and correspondingly, the second pneumatic rotary joint assembly 600 has four air inlets;

[0056] After a set of needle claw seats 301 peel off an independent foam waste, the second air supply channel 309 is inflated through the second pneumatic rotary joint assembly 600 and sprayed from the air nozzle 308, so that the foam waste on the rotary seat 300 can be blown off and collected, realizing efficient waste collection. At this time, the hook needle 3011 is in a reset state, that is, retracted into the needle claw seat 301;

[0057] Further, such as Figure 1As shown in , it also includes a waste collection channel 105 arranged on one side of the rotating seat 300, which is used to collect the foam waste caught by the hook needle 3011; the middle part of the die-cutting machine 100 is also provided with a first movable slot 106 for the foam raw material 200 to be pulled downward, and the end of the die-cutting machine 100 is provided with a second movable slot 107 located below the waste collection channel 105. After die-cutting, the foam raw material 200 is pulled into the first movable slot 106 and pulled out from the second movable slot 107. The purpose of such design is, firstly, to better collect the grabbed foam waste on the rotating seat 300, that is, the foam waste on the rotating seat 300 can be blown down to the waste collection channel 105 at the lower right by the corresponding air nozzle 308, and secondly, to enable the die-cut carrier layer to be transported linearly from the bottom of the waste collection channel 105 with the formed foam, so as to facilitate other subsequent processing processes;

[0058] Furthermore, the waste collection channel 105 includes a first collection channel which is concave and wide at the top and narrow at the bottom, so that the foam waste can fall into it. The bottom of the first collection channel also has a material guide channel which is inclined downward and connected to the outside of the die-cutting machine 100, so that the foam waste can be discharged out of the die-cutting machine 100 in a centralized manner. Correspondingly, a waste collection box can be placed at the outlet of the material guide channel to collect the foam waste in a centralized manner.

[0059] Further, such as Figure 4 As shown in the figure, a mounting rod 503 is fixed in the middle of the rotating seat 300, and both ends of the mounting rod 503 extend to the outside of the rotating seat 300. The two rotor components 502 are respectively fixed to the corresponding ends of the mounting rod 503 by fasteners, that is, the rotor components 502 of the first pneumatic rotating joint assembly 500 and the second pneumatic rotating joint assembly 600 are both hollow so that they can be installed on the rotating seat 300 through the mounting rod 503.

[0060] Further, such as Figure 1 and Figure 4 As shown in the figure, bearing seats for installing the rotating shaft 302 are respectively installed at both ends of the die-cutting machine 100, and the rotating shaft 302 is connected to the driving member inside the die-cutting machine 100 through the pulley assembly 400. The top of the die-cutting machine 100 has an installation slot for the pulley assembly 400 to pass through, wherein the driving member is preferably a motor plus a power shaft mode (only the power shaft is shown in this embodiment), and the pulley assembly 400 is installed between the power shaft and the rotating shaft 302. In this way, it is convenient to install the corresponding first pneumatic rotary joint assembly 500 and the second pneumatic rotary joint assembly 600 at both ends of the rotating seat 300, so as to realize the driving of the crochet needle 3011 and the blowing of the foam waste.
