Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and in particular to a horizontal punching device for a frame. Background Technology

[0002] Photovoltaic modules are devices used to convert solar energy into electrical energy, and are generally assembled from photovoltaic panels and frames. The frames often have holes for fixing or threading wires. The frames are typically made by cutting long strips of profile; these holes are not originally present in the profiles and need to be punched out before framing.

[0003] Chinese patent CN221434655U discloses a horizontal punching die for a photovoltaic aluminum frame, capable of punching the workpiece horizontally, eliminating the need for workpiece flipping. However, all the punching components are fixed to individual connecting blocks and cannot be adjusted arbitrarily. In actual production, the frame lengths vary, and the punching positions also differ, making this die inflexible in adjustment.

[0004] Therefore, it is necessary to improve the structure of the punching unit to solve the above problems. Utility Model Content

[0005] The main purpose of this utility model is to provide a horizontal punching device for frames that can flexibly adapt to the punching needs of frames of different lengths and with different hole positions.

[0006] This utility model achieves the above objective through the following technical solution: a horizontal punching device for a frame, comprising:

[0007] A plurality of horizontal punching dies, including a moving module, a stripper plate and a fixed module arranged sequentially along the X direction, wherein the moving module is provided with a plurality of punches passing through the stripper plate and the fixed module along the X direction;

[0008] The movable frame has a Y-direction slide groove along its length. All moving modules are connected side by side to the movable frame along the Y-direction through a connecting component. All connecting components move along the Y-direction slide groove.

[0009] A fixed frame, located on the opposite side of the movable frame in the X direction, fixes all fixed modules side by side along the Y direction;

[0010] A punching drive component is fixed relative to the fixed frame and drives the movable frame to move along the X direction.

[0011] Specifically, the punching drive consists of two hydraulic cylinders connected to the fixed frame, with the drive heads of the two hydraulic cylinders respectively connected to symmetrical positions on both sides of the movable frame.

[0012] Specifically, a waste removal mechanism is provided below the horizontal punching die. The waste removal mechanism includes a waste removal belt extending along the Y direction and two baffles located on both sides of the waste removal belt in the X direction.

[0013] Specifically, the Y-axis slide is located on the upper surface of the movable frame and has an inverted T-shaped cross-section. The connecting assembly includes a connecting block fixed to the upper part of the movable module and a screw passing through the connecting block, with the head of the screw extending into the Y-axis slide.

[0014] Specifically, the upper part of the template has a stepped structure, including a support surface and an abutment part located on the side away from the stripper plate, and the support surface is provided with a Y-shaped groove.

[0015] Furthermore, a side push assembly is provided on one side of the fixed frame. The side push assembly includes a side push drive and a push block. The side push drive drives the push block to move along the Y direction. A stop block is provided on the horizontal punch die farthest from the side push assembly. The stop block is connected to the upper surface of the fixed module of the horizontal punch die.

[0016] Furthermore, a pressure frame assembly is provided on each of the two sides of the fixing frame in the Y direction. The pressure frame assembly includes a rotating shaft that is rotatably disposed above the fixing frame in the Y direction, a rotating drive component that drives the rotating shaft to rotate around the Y axis, and a plurality of pressure blocks disposed on the rotating shaft. The pressure blocks press the frame onto the support surface.

[0017] Specifically, the movable frame is located on the discharge side of the fixed frame, and the feed side of the fixed frame is provided with a pre-positioning component. The pre-positioning component includes a bracket, two feed baffles on both sides of the bracket in the Y direction, and two stop baffles on the outlet side of the bracket. The feed baffles open outward on their inlet side.

[0018] Furthermore, the bracket has a Y-axis slide rail on at least one side in the Y direction, a Y-axis slider is fitted on the Y-axis slide rail, a Y-axis cylinder is provided on the Y-axis slider, the Y-axis cylinder drives the feed baffle to move in the Y direction, and a locking handle is provided on the X-axis side of the Y-axis slider, the locking handle fixes the Y-axis slider in position by abutting against the Y-axis slide rail.

[0019] Furthermore, the pre-positioning component also includes multiple contact sensors and two lifting mechanisms. The contact sensors are located between the two stop plates. The lifting mechanism includes a lifting drive located on the feeding side of the stop plate and a support block whose lifting is controlled by the lifting drive. After all the contact sensors detect the signal, the support block rises.

[0020] The beneficial effects of this utility model's technical solution are:

[0021] This horizontal punching device for frames allows the horizontal punching die to be adjusted to any position in the Y direction via a Y-axis slide. Then, it is fixed to the fixed frame by a fixed module to determine the position, so that the horizontal punching die can flexibly adapt to the diverse needs of different length frames and different punching positions.

[0041] 200 - Border, 201 - Ridge. Detailed Implementation

[0042] The present invention will be further described in detail below with reference to specific embodiments.

[0043] Example 1:

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a horizontal punching device 100 for a frame according to this utility model includes a movable frame 2, a fixed frame 3, a punching drive component, and several horizontal punching dies 1. Each horizontal punching die 1 includes a moving module 11, a stripper plate 12, and a fixed module 14 arranged sequentially along the X-direction. The moving module 11 is provided with several punches 13 that pass through the stripper plate 12 and the fixed module 14 along the X-direction. The movable frame 2 is provided with a Y-direction slide groove 21 along its length. All moving modules 11 are connected side-by-side to the movable frame 2 along the Y-direction via a connecting component 15, and all connecting components 15 move along the Y-direction slide groove 21. The fixed frame 3 is located on the opposite side of the movable frame 2 in the X-direction, fixing all fixed modules 14 side-by-side along the Y-direction. The punching drive component is fixed relative to the fixed frame 3 and drives the movable frame 2 to move along the X-direction. The X and Y directions are both in the horizontal plane and perpendicular to each other, while the Z-direction is vertical.

[0045] The horizontal punch die 1 is essentially a horizontally placed ordinary die, with the closing direction being horizontal. Elastic elements are typically provided between the moving module 11 and the stripper plate 12, and between the stripper plate 12 and the stationary module 14, to control their separation. Each horizontal punch die 1 can use the punch 13 to punch a through hole in the frame 200; after punching, the waste material from the hole is discharged downwards. The Y-axis slide 21 allows the horizontal punch die 1 to be adjusted arbitrarily in the Y-axis direction, and then fixed to the fixing frame 3 by the stationary module 14 to determine its position. This allows the horizontal punch die 1 to flexibly adapt to diverse needs for different frame lengths and different punching positions.

[0046] like Figure 1As shown, the punching drive consists of two hydraulic cylinders 4 connected to the fixed frame 3, and the drive heads of the two hydraulic cylinders 4 are respectively connected to symmetrical positions on both sides of the movable frame 2.

[0047] This eliminates the need for a separate punching drive for each horizontal punch die 1. Instead, two hydraulic cylinders 4 drive all horizontal punch dies 1 to punch simultaneously via the movable frame 2, saving on power components. Furthermore, it ensures that the horizontal punch die 1 can perform normal punching regardless of its position.

[0048] like Figure 1 and Figure 7 As shown, a waste discharge mechanism 7 is provided below the horizontal punching die 1. The waste discharge mechanism 7 includes a waste discharge belt line 71 extending along the Y direction and two baffles 72 located on both sides of the waste discharge belt line 71 in the X direction.

[0049] Each punching operation of the horizontal punch 1 produces waste material that falls into the hole. The waste removal conveyor belt 71 collects this waste. Because the horizontal punch dies 1 are arranged side-by-side along the Y-axis with variable spacing, the waste removal conveyor belt 71 must extend along the Y-axis. Once the waste material falls onto the waste removal conveyor belt 71, it is transported to one side for collection. A baffle 72 prevents the waste material from shifting to one side of the waste removal conveyor belt 71, ensuring that the waste material is transported in only one direction.

[0050] like Figure 2 and Figure 6 As shown, the Y-axis slide 21 is located on the upper surface of the movable frame 2 and has an inverted T-shaped cross section. The connecting assembly 15 includes a connecting block 151 fixed to the upper part of the movable module 11 and a screw 152 passing through the connecting block 151. The head of the screw 152 extends into the Y-axis slide 21.

[0051] The diameter of the screw head 152 is greater than the upper width of the Y-direction slide groove 21 and less than the lower width of the Y-direction slide groove 21. This ensures that the screw 152 will not come out when sliding within the Y-direction slide groove 21, thus guaranteeing that the moving module 11 is always semi-suspended on the movable frame 2. In practical applications, the Y-direction slide groove 21 can also be located on the X-direction side of the movable frame 2.

[0052] Example 2:

[0053] like Figure 7 As shown, the difference from Embodiment 1 is that the upper part of the template 14 has a stepped structure, including a support surface 141 and an abutment part 142 located on the side away from the stripper plate 12, and a Y-shaped groove 143 is provided on the support surface 141.

[0054] The frame 200 has a right-angled cross-section and an internal ridge 201. The Y-shaped groove 143 engages with the ridge 201 to prevent the frame 200 from deflecting. The abutment 142 abuts against the outer section of one right-angled side of the frame 200, and the other right-angled side of the frame 200 extends downward between the stripper plate 12 and the stationary module 14. In this way, the frame 200 can be held above the stationary module 14 during punching.

[0055] like Figure 2 , Figure 6 and Figure 7 As shown, a side push assembly 5 is provided on one side of the fixed frame 3. The side push assembly 5 includes a side push drive 51 and a push block 52. The side push drive 51 drives the push block 52 to move along the Y direction. A stop block 16 is provided on the horizontal punch die 1 that is furthest from the side push assembly 5. The stop block 16 is connected to the upper surface of the fixed module 14 of the horizontal punch die 1.

[0056] Regardless of the length of the frame 200, it must be positioned along its length before punching. This is achieved by providing a Y-axis reference using stop 16, and then pushing the frame 200 with push block 52 so that one end of the frame 200 rests against stop 16, thus completing the positioning. To ensure the correct punching position at the far side, the position of stop 16 relative to positioning module 14 needs to be adjustable. This ensures that the punching position of each frame 200 meets the requirements.

[0057] like Figure 1 , Figure 2 and Figure 8 As shown, each of the two sides of the fixed frame 3 in the Y direction is provided with a pressing frame assembly 6. The pressing frame assembly 6 includes a rotating shaft 61 that is rotatably disposed above the fixed frame 3 in the Y direction, a rotating drive 62 that drives the rotating shaft 61 to rotate around the Y axis, and a plurality of pressing blocks 63 disposed on the rotating shaft 61. The pressing blocks 63 press the frame 200 onto the support surface 141.

[0058] If the frame 200 is not restrained at the top when placed on the horizontal punch die 1, it is easy to fall out of the punching position due to the pushing force of the push block 52, thus preventing normal punching. Before the frame 200 is in place, the pressure block 63 is turned outward and located outside the upper projection range of the frame 200; after the frame 200 is in place, the rotary drive 62 rotates through the drive shaft 61, causing the pressure block 63 to press down on the frame 200. In this way, the position of the frame 200 can be better controlled during side-push positioning and punching, ensuring normal punching.

[0059] Example 3:

[0060] like Figure 1 , Figure 3 , Figure 4 and Figure 9As shown, the difference from Embodiment 2 is that the movable frame 2 is located on the discharge side of the fixed frame 3, and the feed side of the fixed frame 3 is provided with a pre-positioning component 8. The pre-positioning component 8 includes a bracket 81, two feed baffles 82 on both sides of the bracket 81 in the Y direction, and two stop baffles 83 on the outlet side of the bracket 81. The inlet side of the feed baffles 82 opens outward.

[0061] The pre-positioning component 8 provides a pre-positioning station located in front of the punching station (i.e., above the horizontal punch die 1). The frame 200 is transferred from the pre-positioning station to the punching station by other transfer mechanisms. Because there is a punching drive component on one side of the movable frame 2, which will affect the distance between the two stations, the movable frame 2 is preferably located on the exit side of the punching station to shorten the distance between the two stations. The feed side of the pre-positioning component 8 receives the feed conveyor line, and the frame 200 will move along the X direction into the space between the two guide baffles 82. However, the Y-direction position of the frame 200 is uncertain. Without pre-positioning, it cannot be guaranteed that it will be located between the stop block 16 and the push block 52 when it moves to the punching station. Therefore, the pre-positioning component 8 is used to pre-position the frame 200. The inlet side of the guide baffle 82 needs to be slightly open to facilitate the movement of the frame 200. The two stop plates 83 can abut against the front of the frame 200, so that the frame 200 can stop at the pre-positioning station with its length along the Y direction.

[0062] like Figure 3 As shown, Y-direction slide rails 84 are provided on both sides of the bracket 81 in the Y direction. Y-direction sliders 85 are provided on the Y-direction slide rails 84. Y-direction cylinders 86 are provided on the Y-direction sliders 85. The Y-direction cylinders 86 drive the feed baffle 82 to move in the Y direction. A locking handle 87 is provided on the X-direction side of the Y-direction slider 85. The locking handle 87 fixes the Y-direction slider 85 in a fixed position by abutting against the Y-direction slide rails 84.

[0063] The material guide baffle 82 can adjust its Y-direction position by moving the Y-direction slider 85 along the Y-direction slide rail 84, thereby controlling the distance between the two material guide baffles 82. This can meet the pre-positioning requirements of frame 200 of different lengths. The distance between the two material guide baffles 82 can also be temporarily increased by the Y-direction cylinder 86. After the frame 200 reaches the pre-positioning station, the Y-direction cylinder 86 drives the two material guide baffles 82 closer together, so that the frame 200 reaches the required position. In practical applications, the position of the material guide baffle 82 on the side closer to the stop block 16 can remain unchanged, while the material guide baffle 82 on the other side is equipped with the Y-direction slide rail 84, Y-direction slider 85, and Y-direction cylinder 86. This ensures that the frame 200 is at least located inside the stop block 16.

[0064] like Figure 7 and Figure 9As shown, the pre-positioning component 8 also includes multiple contact sensors 88 and two lifting mechanisms 89. The contact sensors 88 are located between two stop plates 83 and are positioned close to the stop plates 83. The lifting mechanism 89 includes a lifting drive 891 located on the feeding side of the stop plate 83 and a support block 892 whose lifting is controlled by the lifting drive 891. After all the contact sensors 88 sense the signal, the support block 892 is raised.

[0065] In this embodiment, the lower part of the frame 200 in the punched state is not a plane, so its initial posture does not meet the requirements for horizontal punching when it is fed from the feeding conveyor line. Therefore, another function of the straightening component 8 is to adjust the state of the frame 200 so that the punched edge rotates to the vertical direction. When the frame 200 is about to contact the stop plate 83, the contact sensor 88 will sense the arrival of the frame 200, thereby causing the support block 892 to lift the frame 200. Under the combined action of the support block 892 and gravity, the frame 200 can spontaneously adjust its position to the required state. Because it is necessary to prevent the frame 200 itself from being skewed, which would cause a certain support block 892 to not be in the required position, there are at least two contact sensors 88 to ensure that the length of the frame 200 is along the Y direction when it is in place.

[0066] The working process of the horizontal punching device 100 for this frame is as follows:

[0067] 1. Feeding: The frame 200 to be punched is fed from the feeding conveyor line to the prepositioning component 8. At this time, the corner of the frame 200 is upward and the bottom is tilted, until it reaches between the two feeding baffles 82.

[0068] 2. Pre-positioning: When the frame 200 touches the contact sensors 88 on both sides, the lifting drive 891 drives the support block 892 to rise, which, together with the stop plate 83, makes the frame 200 rotate, so that one right-angle side is facing upward and the other right-angle side (i.e. the surface to be punched) is facing backward. At the same time, the two guide plates 82 move closer to each other along the Y direction until both ends of the frame 200 are abutted, thus completing the pre-positioning.

[0069] 3. Transfer: The transfer mechanism takes the frame 200 from above the prepositioning component 8 and places it on the open horizontal punching die 1. The prepositioning component 8 is reset. At this time, the right-angled edge of the frame 200 falls between the stripper plate 12 and the fixed module 14, and its lower ridge 201 is stuck in the Y-direction groove 143.

[0070] 4. Mold closing: Rotary drive 62 causes pressure block 63 to rotate, pressing down on the upward right-angled edge of frame 200. Side push drive 51 drives push block 52 to insert and push one end of frame 200, so that the other end of frame 200 abuts against stop block 16. Then hydraulic cylinder 4 drives all moving modules 11 to move together towards fixed module 14. Stripper plate 12 first cooperates with fixed module 14 to clamp the surface to be punched, and then punch 13 punches small holes on the surface.

[0071] 5. Mold opening: Punch 13, pressure block 63, and push block 52 are reset respectively, and the hole waste falls naturally onto the waste discharge belt 71. The waste discharge belt 71 discharges the hole waste to the Y-direction side, and the frame 200 with the hole already punched is moved to the next process.

[0072] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
