Description

Technical Field

[0001] This utility model relates to the field of tape punching technology, specifically to a multi-aperture switching module for a photovoltaic tape punching machine. Background Technology

[0002] Photovoltaic tape comes in different widths, and the width, perforation style, and density of photovoltaic tape need to be adjusted according to the application scenario and customer requirements.

[0003] When using needle rollers to punch holes in a mechanical punching machine, the type of needle roller needs to be adjusted according to the punching requirements. The needle rollers are all mounted on the shaft. When replacing them, the fixing structure between the needle roller and the shaft needs to be removed first, and then the needle roller can be taken off the shaft.

[0004] This paper presents a multi-aperture switching module for a photovoltaic tape punching machine. The traditional mounting shaft structure is eliminated and replaced with a new and improved clamping mechanism. Different types of needle rollers and clamping mechanisms are modularly improved. Utility Model Content

[0005] (a) Technical issues

[0006] The present invention aims to at least solve the problem of frequent replacement of needle rollers in the process of personalized customization of photovoltaic tapes in the prior art.

[0007] (II) Technical Content

[0008] This solution provides a multi-aperture switching module for a photovoltaic tape punching machine, achieved through the following specific technical means: including a frame, on which a crossbeam is fixed, and multiple sets of punching units are distributed on the crossbeam; each set of punching units consists of two sets of mounting plates and a needle roller module located between the two sets of mounting plates and held by the two sets of mounting plates;

[0009] The top of the mounting plate frame is detachably fixed to the crossbeam, and a tube is rotatably installed through the mounting plate frame. The needle roller module has a cylindrical structure and its two ends are respectively inserted into the inner ends of the tubes on the two sets of mounting plate frames. At the same time, the inner sides of the two sets of mounting plate frames are in contact with the two end faces of the needle roller module.

[0010] A rubber roller that mates with the needle roller module is rotatably mounted on the frame below the needle roller module.

[0011] Preferred technical solution 1: The outer ends of two adjacent sets of tubes are connected by a telescopic tube; the telescopic tube, tubes and needle roller modules form a channel, which allows cooling air to enter and cool the needle roller modules.

[0012] Preferred technical solution 2: A power shaft is rotatably mounted on the frame, and a sleeve is rotatably mounted on the tail end of the mounting plate frame. The sleeve is also sleeved on the power shaft and slidably connected to the power shaft.

[0013] Sprockets are fixedly fitted on the outer end of the tube and the sleeve, and a chain belt is fitted between the two sets of sprockets. The chain belt and sprockets are used to synchronously drive the needle modules in the multiple piercing units to rotate.

[0014] Preferred technical solution 3: The mounting plate extends downward from the bottom side to form a vertical plate, and a vertical hole is provided on the vertical plate. The diameter of the vertical hole is not less than the diameter of the rubber roller. The rubber roller passes through the vertical hole to define the position of the tape on the rubber roller.

[0015] Preferred technical solution four: The surface speed of the needle roller module is the same as that of the rubber roller.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 The multi-aperture switching module of the photovoltaic tape punching machine includes a frame 1. The frame 1 is mounted on the punching machine and located between the unwinding mechanism and the rewinding mechanism on the front and rear sides of the punching machine. The unwinding mechanism and the rewinding mechanism are existing technologies and have not been improved in this solution, so their specific structures will not be described in detail. The specific improved structure is as follows:

[0028] A crossbeam 2 is fixed on the frame 1, and multiple sets of piercing units 3 are distributed on the crossbeam 2; each set of piercing units 3 consists of two sets of mounting plates 31 and a needle roller module 32 located between the two sets of mounting plates 31 and clamped by the two sets of mounting plates 31.

[0029] The top of the mounting plate frame 31 can be detachably fixed to the crossbeam 2 (if it is fixed to the crossbeam 2 with bolts, when the needle roller module 32 needs to be replaced, only the position of the mounting plate frame 31 on the crossbeam 2 needs to be moved). At the same time, tubes 33 are rotatably installed in the opposite positions of the two sets of mounting plate frames 31. The needle roller module 32 is a cylindrical structure with open ends, and needles are distributed on the cylindrical surface. The two ends of the needle roller module 32 are respectively inserted into the inner ends of the tubes 33 on the two sets of mounting plate frames 31 (the inner wall of the needle roller module 32 has a limiting strip that matches the limiting groove of the outer wall of the tube 33. During assembly, the limiting strip is inserted into the limiting groove to achieve a stable radial connection between the tube 33 and the needle roller module 32). At the same time, the inner sides of the two sets of mounting plate frames 31 contact the two end faces of the needle roller module 32 to complete the clamping and installation of the needle roller module 32.

[0030] A rubber roller 4 is rotatably mounted on the frame 1 below the needle roller module 32. The tape passes over the rubber roller 4. The roller speeds of the needle roller module 32 and the rubber roller 4 are the same. The rubber roller 4 and the needle roller module 32 cooperate to complete the punching operation on the tape.

[0031] In one embodiment

[0032] Please see Figure 1 The outer end of the tube 33 in one set of piercing units 3 is connected to the outer end of the tube 33 in another set of adjacent piercing units 3 by a telescopic tube 5.

[0033] Multiple piercing units 3 are connected by the telescopic tube 5. The telescopic tube 5, the tube 33 and the cylindrical structure of the needle roller module 32 together form a channel. The channel allows cooling air to enter and cool the needle roller module 32 (which is made of thermally conductive material) during operation, preventing the needle from deforming due to heat during operation. In use, the air supply pipe of the external air supply device is inserted into one end of the channel to discharge cooling air into the channel. The cooling air flows through the channel to cool the needle roller module 32.

[0034] In one embodiment

[0035] Please see Figures 1-4 A power shaft 6 is also rotatably mounted on the frame 1. The tail end of the mounting plate 31 extends toward the power shaft 6, and a hole is provided at the rear end for the power shaft 6 to pass through. The size of the hole is larger than the diameter of the power shaft 6.

[0036] A sleeve 34 is rotatably installed in the hole, and the sleeve 34 is also sleeved on the power shaft 6 and slidably connected to the power shaft 6 (for example, an axial groove is formed on the outer wall of the power shaft 6, and a protrusion extends into the long groove and can slide along the long groove on the inner wall of the sleeve 34). Thus, while the power shaft 6 drives the sleeve 34 to rotate synchronously, the axial position of the sleeve 34 on the power shaft 6 can also be moved. A sprocket 35 is fixedly sleeved on both the outer end of the tube 33 and the sleeve 34, and a chain belt 36 is sleeved between the two sets of sprockets 35. The arrangement of the chain belt 36 and the sprockets 35 achieves the technical effect of the power shaft 6 synchronously driving the needle modules in multiple sets of piercing units 3 to rotate.

[0037] In one embodiment

[0038] Please see Figure 1 , Figure 2 An end seat 7 is installed at the end of the rubber roller 4. The rubber roller 4 is rotatably mounted on the end seat 7. At the same time, a telescopic rod 8 is connected between the end seat 7 and the frame 1 (the outer shell of the telescopic rod 8 is fixed on the frame 1, and the top telescopic end is fixed on the end seat 7. It is worth noting that the type, specific model, and matching power supply and control switch of the telescopic rod 8 mentioned in this embodiment can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated). The distance between the rubber roller 4 and the needle roller module 32 is controlled by the extension and retraction of the telescopic rod 8. Thus, when replacing the needle roller module 32, the rubber roller 4 is first moved away from the needle roller module 32 to avoid obstructing the operating space, and it is also convenient for the feeding of the tape. After the replacement is completed, the rubber roller 4 is pushed closer to the needle roller module 32.

[0039] A motor mounting position is provided on the end seat 7, where a set of motors can be fixed and their output shafts can be connected to the end of the rubber roller 4; at the same time, another motor mounting position is also provided on the frame 1 near the power shaft 6 for another motor connected to the power shaft 6 to be installed. The two sets of motors drive the rubber roller 4 and the spiked roller module 32 to rotate at the same speed.

[0040] In one embodiment

[0041] Please see Figure 2 , Figure 3 , Figure 4 The mounting plate 31 extends downward from the bottom side to form a vertical plate 311, and a vertical hole 312 is provided on the vertical plate 311. The diameter of the vertical hole 312 is not less than the diameter of the rubber roller 4. The rubber roller 4 passes through the vertical hole 312 and does not contact the wall of the vertical hole 312.

[0042] The vertical plate 311 is used to limit the position of the tape on the rubber roller 4 to prevent the tape from being misaligned.

[0043] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.
