[0002] The EVA cutting machine used in the field of photovoltaic module production is used to lay EVA and backboard. This type of cutting machine generally includes a feeding mechanism, a material head traction mechanism, a feeding mechanism, a punching mechanism, a cutting mechanism, a pulling mechanism, a pressing mechanism, etc. Traditional cutting machines are generally single-head cutting machines. The feeding mechanism of this type of cutting machine generally includes a feeding shaft. After the EVA coil on the feeding shaft is laid, the feeding shaft needs to be removed, and then a new EVA coil is reinstalled on the feeding shaft, and then the feeding shaft is installed on the support frame of the feeding mechanism. The whole process takes a long time, and during this replacement process, the cutting machine is in a shutdown state, which greatly affects the production efficiency.

[0003] To solve the above problems, a double-head cutting machine is currently used.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a dual-axis cutting machine for cutting EVA, including a feeding mechanism 100 and a material head traction mechanism 200, the feeding mechanism 100 includes a support frame 101, an upper support shaft 102, a lower support shaft 103 and a first driving assembly 104, the upper support shaft 102 is detachably mounted on the support frame 101, the upper support shaft 102 is connected to the first driving assembly 104, the first driving assembly 104 is used to drive the upper support shaft 102 to rotate, the lower support shaft 103 is detachably mounted on the support frame 101, the lower support shaft 103 is located below the upper support shaft 102, the lower support shaft 103 is connected to the second driving assembly 105, The second driving assembly 105 is used to drive the lower support shaft 103 to rotate, and the material head traction mechanism 200 is arranged on one side of the support frame 101. The material head traction mechanism 200 includes a third driving assembly, a conveying assembly, an upper chuck assembly and a lower chuck assembly. The third driving assembly is connected to the conveying assembly. The third driving assembly is used to drive the conveying assembly to move, the upper chuck assembly is connected to the conveying assembly, the lower chuck assembly is connected to the conveying assembly, and the lower chuck assembly is located below the upper chuck assembly. When the conveying assembly is running, the upper chuck assembly and the lower chuck assembly move synchronously, and the movement directions of the upper chuck assembly and the lower chuck assembly are opposite.

[0052] When the above-mentioned cutting machine is in use, the EVA coil 10 can be loaded on the upper support shaft 102 and the lower support shaft 103 respectively. After the EVA coil 10 on the upper support shaft 102 is laid, the EVA coil 10 on the lower support shaft 103 can be laid next. At the same time, the upper support shaft 102 can be removed, and the EVA coil 10 can be reloaded on the upper support shaft 102, and then the upper support shaft 102 can be reinstalled on the support frame 101. After the EVA coil 10 on the lower support shaft 103 is laid, the EVA coil 10 on the upper support shaft 102 can be used next, and at the same time, the lower support shaft 103 can be removed, and a new EVA coil 10 can be loaded on the lower support shaft 103, and so on. Since the cutting machine continues to work while loading a new EVA coil 10, the production efficiency can be improved. At the same time, since the two supporting shafts are arranged up and down, and the material head traction mechanism 200 can be arranged on the same frame together with the punching mechanism, etc., it can effectively save floor space and reduce costs.

[0053] In this embodiment, the upper support shaft 102 includes a first main shaft body and support structures 109 arranged at both ends of the first main shaft body, the upper support shaft 102 also includes a first protrusion 114 connected to the first main shaft body and arranged on the outside of one of the support structures 109, two upper support shaft receiving grooves are arranged at intervals on the support frame 101, and the two support structures 109 are respectively located in the two upper support shaft receiving grooves, and a quick pressing clamp 110 is arranged on the support frame 101 on the outside of the upper support shaft receiving groove, and the quick pressing clamp 110 is used to press the corresponding support structure 109 into the upper support shaft receiving groove, the first driving assembly includes a first motor assembly 111, a first reduction assembly 112 and a first transmission shaft 113, the first motor assembly 111 is connected to the first reduction assembly 112, the first reduction assembly 112 is connected to the first transmission shaft 113, and the end of the first transmission shaft 113 is provided with a first through groove 113a, and the first through groove 113a is used to accommodate the first protrusion 114. The first motor assembly 111 drives the first transmission shaft 113 to rotate through the first reduction assembly 112 , and then drives the upper support shaft 102 to rotate through the cooperation between the first protrusion 114 and the first through slot 113 a .

[0054] Specifically, the first main shaft body can rotate relative to the support structure 109. The support structure 109 can be a support structure of a bearing or the like.

[0055] Specifically, the first motor assembly 111 may be a servo motor assembly, etc. It is understandable that the first motor assembly 111 may also be other types of motor assemblies.

[0056] Specifically, the first reduction assembly 112 may be a worm gear reducer, etc. It is understandable that the first reduction assembly 112 may also be other types of reduction assemblies.

[0057] Specifically, the first protrusion 114 can enter the first through-slot 113a from one side of the first through-slot 113a, and can also be moved out of the first through-slot 113a.

[0058] In this embodiment, a first proximity switch group 115 is arranged on the support frame below the first transmission shaft 113, and a first induction sheet matching the first proximity switch group 115 is arranged on the first transmission shaft 113. When the first transmission shaft 113 is rotated until the first through slot 113a thereon is in a horizontal position so that the first protrusion 114 can be moved out of the first through slot 113a, the first induction sheet is located within the induction range of the first proximity switch group 115, the first proximity switch group 115 generates a stop signal, and the first motor assembly 111 stops running.

[0059] It should be noted that when the above two upper support shaft receiving grooves are set, the opening direction of the upper support shaft receiving grooves is preferably set horizontally, so that the upper support shaft moves in the horizontal direction, and then the support structures 109 at both ends of the upper support shaft enter the corresponding upper support shaft receiving grooves horizontally. Correspondingly, the first protrusion 114 set at the end of the upper support shaft also enters the first through groove 113a in the horizontal direction. Then the quick pressing clamp 110 is closed to press the support structure 109 in the upper support shaft receiving groove. The above setting method makes it preferable that the first through groove 113a is also located in a horizontal position when the upper support shaft needs to be removed. In this way, the quick pressing clamp 110 is first opened so that the two support structures 109 of the upper support shaft can be removed from the upper support shaft receiving groove, and at the same time, the first protrusion 114 can also be removed from the first through groove 113a in the horizontal direction. The setting of the above first proximity switch group 115 and the first sensor sheet can conveniently make the first through groove 113a in a horizontal state, thereby facilitating the removal of the upper support shaft.

[0060] In this embodiment, the lower support shaft 103 includes a second main shaft body and a support structure 109 arranged at both ends of the second main shaft body. The lower support shaft 103 also includes a second protrusion 120 connected to the second main shaft body and arranged on the outside of one of the support structures 109. Two lower support shaft receiving grooves are arranged on the support frame 101 at intervals. The two support structures 109 are respectively located in the two lower support shaft receiving grooves. A quick pressing clamp 110 is arranged on the support frame 101 on the outside of the lower support shaft receiving groove. The quick pressing clamp 110 is used to press the corresponding support structure 109 into the lower support shaft receiving groove. The second driving assembly includes a second motor assembly 116, a second reduction assembly 117 and a second transmission shaft 118. The second motor assembly 116 is connected to the second reduction assembly 117, and the second reduction assembly 117 is connected to the second transmission shaft 118. The end of the second transmission shaft 118 is provided with a second through groove 118a, and the second through groove 118a is used to accommodate the second protrusion 120. The second motor assembly 116 drives the second transmission shaft 118 to rotate through the second reduction assembly 117 , and then drives the lower support shaft to rotate through the cooperation between the second protrusion 120 and the second through slot 118 a .

[0061] Specifically, the second main shaft body can rotate relative to the support structure 109. The support structure 109 can be a support structure of a bearing or the like.

[0062] Specifically, the second motor assembly 116 may be a servo motor assembly, etc. It is understandable that the second motor assembly 116 may also be other types of motor assemblies.

[0063] Specifically, the second reduction assembly 117 may be a worm gear reducer, etc. It is understandable that the second reduction assembly 117 may also be other types of reduction assemblies.

[0064] Specifically, the second protrusion 120 can enter the second through-slot 118a from one side of the second through-slot 118a, and can also be moved out of the second through-slot 118a.

[0065] In this embodiment, a second proximity switch group 121 is arranged on the support frame below the second transmission shaft 118, and a second induction sheet matching the second proximity switch group 121 is arranged on the second transmission shaft 118. When the second transmission shaft 118 is rotated until the second through slot 118a thereon is in a horizontal position so that the second protrusion 120 can be moved out of the second through slot 118a, the second induction sheet is located within the induction range of the second proximity switch group 121, the second proximity switch group 121 generates a stop signal, and the second motor assembly 116 stops running.

[0066] It should be noted that when the two lower support shaft receiving grooves are set, the opening direction of the lower support shaft receiving grooves is preferably set horizontally, so that the lower support shaft moves in the horizontal direction, and the support structures 109 at both ends of the lower support shaft enter the corresponding lower support shaft receiving grooves horizontally. Correspondingly, the second protrusion 120 set at the end of the lower support shaft also enters the second through groove 118a in the horizontal direction. Then the quick pressing clamp 110 is closed to press the support structure 109 in the lower support shaft receiving groove. The above setting method makes it better that the second through groove 118a is also in a horizontal position when the lower support shaft needs to be removed. In this way, the quick pressing clamp 110 is opened first, so that the two support structures 109 of the lower support shaft can be moved out of the lower support shaft receiving groove, and at the same time, the second protrusion 120 can also be moved out of the second through groove 118a in the horizontal direction. The setting of the second proximity switch group 121 and the second sensor sheet can make it convenient to put the second through groove 118a in a horizontal state, so as to facilitate the removal of the above lower support shaft.

[0067] In this embodiment, the upper clamp assembly includes an upper support plate 205 and a plurality of clamps 206 spaced apart on the upper support plate 205, and both ends of the support plate are connected to the conveying assembly. The clamps 206 can be quick clamps, etc. The clamps 206 are used to clamp and fix the material head of the coil.

[0068] In this embodiment, the lower clamp assembly includes a lower support plate 207 and a plurality of clamps 206 spaced apart on the lower support plate 207, and both ends of the support plate are connected to the conveying assembly. The clamps 206 can be quick clamps, etc. The clamps 206 are used to clamp and fix the material head of the coil.

[0069] Specifically, the material head traction mechanism 200 can be installed together with the feeding mechanism 300 and the cutting mechanism 500 on a frame. The third driving assembly can include a third motor assembly, and the conveying assembly can include a first sprocket group 202, a second sprocket group 203, a material head traction mechanism transmission shaft 209, a first chain 201 and a second chain 204. The first sprocket group 202 and the second sprocket group 203 can be arranged on the frame at intervals, the first sprocket group 202 is provided with a first chain 201, and the second sprocket group 203 is provided with a second chain 204. The first chain 201 forms two layers on the first sprocket group 202. The second chain 204 forms two layers on the second sprocket group 203. The material head traction mechanism transmission shaft 209 is connected to the first sprocket group 202 and the second sprocket group 203 respectively, so as to make the first sprocket group 202 and the second sprocket group 203 move synchronously. The two ends of the upper support plate 205 are respectively connected to the upper layer of the first chain 201 and the upper layer of the second chain 204, and the two ends of the lower support plate 207 are respectively connected to the lower layer of the first chain 201 and the lower layer of the second chain 204. The third motor assembly is used to drive the first sprocket group 202 to move. Due to the provision of the material head traction mechanism transmission shaft 209, the second sprocket group 203 moves synchronously, thereby making the first chain 201 and the second chain 204 move synchronously. In this way, the upper support plate 205 and the lower support plate 207 move in opposite directions.

[0070] Specifically, the upper chuck assembly corresponds to the upper support shaft 102 and is used to clamp and fix the material head of the EVA coil 10 on the upper support shaft 102. The lower chuck assembly corresponds to the lower support shaft 103 and is used to clamp and fix the material head of the EVA coil 10 on the lower support shaft 103. The upper chuck assembly and the lower chuck assembly move under the drive of the conveying assembly, and the specific movement directions are opposite, that is, when the upper chuck assembly moves toward the upper support shaft 102, the lower chuck assembly moves in a direction away from the lower support shaft 103. After moving to a predetermined position, the material head of the EVA coil 10 on the upper support shaft 102 can be clamped and fixed by the upper chuck assembly. Then, the upper chuck assembly moves in a direction away from the upper support shaft 102, and with the cooperation of the feeding mechanism 300, the material head passes through the floating roller of the floating mechanism 910, the feeding mechanism 300 and the cutting mechanism 500 in sequence. It should be noted that the feeding mechanism 300 includes a pressing roller 310, a feeding roller 320, and a pressing roller driving cylinder that drives the pressing roller to move up and down. The pressing roller driving cylinder first drives the pressing roller 310 to rise, so that the material head can pass between the pressing roller 310 and the feeding roller 320. After the material head passes through the feeding mechanism 300 and the cutting mechanism 500, the pressing roller 310 of the feeding mechanism is driven by the pressing roller driving cylinder to descend and press the EVA material. The floating roller descends to tighten the material, and then the material head is cut off by the cutter assembly (including the upper cutter 510 and the lower cutter 520) of the cutting mechanism 500 to complete the feeding function. After the loading is completed, the feeding roller 320 of the feeding mechanism rotates under the drive of its driving motor to transport the EVA material forward. The EVA material passes through the receiving platform 630 of the pressing mechanism 600 and reaches the clamping claw 720 of the pulling mechanism 700. The material is clamped by the clamping claw 720. The pulling mechanism 700 moves backward under the drive of its driving motor. After the material is pulled to a specified length, the pressing cylinder of the pressing mechanism 600 descends to press the material, and the upper cutter 510 and the lower cutter 520 of the cutting mechanism 500 cooperate to cut the material. Then, the pressing mechanism 600 and the pulling mechanism 700 move forward to the specified position at the same time. The lifting conveyor 800 rises, and the pressing mechanism 600 and the pulling mechanism 700 release the material. The material is laid on the components pre-placed on the lifting conveyor 800. Then, the lifting conveyor 800 descends, the return mechanism 930 and the blocking mechanism 920 are reset, the above components are output, and the pressing mechanism 600 and the pulling mechanism 700 are reset. Enter the next component laying process. In the above process, the lower layer chuck assembly moves toward the lower support shaft 103 to the outside of the lower support shaft 103. After the EVA coil 10 on the upper support shaft 102 is laid, the material head of the EVA coil 10 on the lower support shaft 103 can be clamped and fixed by the lower layer chuck assembly, and then the lower layer chuck assembly is moved in the direction away from the lower support shaft 103, and automatically sent to the position of the cutting mechanism 500 with the cooperation of the feeding mechanism 300, and the material head is cut off by the cutting mechanism 500 to complete the feeding function.Then repeat the above process to lay the EVA material on the assembly. In the above process, the upper clamp assembly moves to the outer side of the upper support shaft 102 in the direction of the upper support shaft 102, waiting for re-loading.

[0071] It should be noted that the above-mentioned material pressing mechanism 600 includes a material pressing support 610 and a plurality of material pressing cylinders 620 arranged on the material pressing support 610 , and a material receiving platform 630 arranged below the material pressing cylinders 620 .

[0072] It should be noted that the above-mentioned clamping mechanism includes a clamping bracket and a plurality of clamping claws 720 arranged on the clamping bracket.

[0073] It should be noted that the above-mentioned lifting conveyor 800 includes a lifting mechanism 810 and a conveying mechanism 820 arranged on the lifting mechanism 810.
