Description

[Technical field]

[0001] The utility model belongs to the technical field of photovoltaic component production, in particular to a fast beating mechanism. [Background technology]

[0002] There is a process in the production of photovoltaic modules that requires shaping and straightening the leads on the modules. In the prior art, most of the shaping of the leads is done by pulling them straight, but the shaping effect is limited, and the leads easily rebound to a skewed state. Patent publication number CN214563941U in the prior art is a marking pneumatic hammering device, which has a complex structure and large size. There are three pairs of leads on the photovoltaic module in the length direction of the short side, and there are two leads in each pair of leads. When correcting the leads, both leads need to be shaped and corrected at the same time. Therefore, the above-mentioned pneumatic hammering device cannot be directly applied to the photovoltaic module lead shaping equipment due to its large size.

[0003] Therefore, it is necessary to provide a new fast beating mechanism to solve the above-mentioned technical problems. [Contents of the utility model]

[0004] The main purpose of the utility model is to provide a fast hammering mechanism with a simple structure and small overall size, which is suitable for occasions where fast hammering is required in a small space.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a fast hammering mechanism, which includes an air block, a piston rod and a striking block; an air chamber is arranged in the air block; a piston block is formed at one end of the piston rod and extends into the air chamber, and the other end extends out of the air block, and the striking block is installed at the other end of the piston rod; the air chamber is divided into a first chamber and a second chamber distributed on the left and right by the piston block, and the air block is provided with an air inlet hole that is always connected with the second chamber and an exhaust hole that is arranged on the movable path of the piston rod avoiding the air chamber; a first channel that conducts the first chamber and the second chamber in a retracted state and a second channel that conducts the first chamber and the exhaust hole in an extended state are arranged in the piston rod.

[0006] Furthermore, a plurality of gas paths are arranged in the piston rod, and the gas paths include a first gas path extending axially to the right from the end of the piston block, a second gas path and a third gas path extending from the first gas path to the outer peripheral surface of the piston rod, and the second gas path and the third gas path are distributed axially along the first gas path; the first gas path and the second gas path constitute the first channel, and the first gas path and the third gas path constitute the second channel.

[0007] Furthermore, an axial distance between the second gas path and the third gas path is smaller than a corresponding distance between the gas inlet hole and the gas outlet hole.

[0008] Furthermore, a stepped axial hole penetrating the left and right surfaces is provided in the gas block, a section of the axial hole with a large inner diameter forms the air chamber, and a section of the axial hole with a small inner diameter forms a guide limit hole for the left and right movement of the piston rod.

[0009] Furthermore, a cover plate is provided at the left end of the gas block, and the cover plate and the gas block are sealed and connected via a sealing ring.

[0010] Furthermore, it also includes an air circuit connection block, which is arranged on the upper surface of the air block; an air intake channel connected to the air intake hole and an air discharge channel connected to the exhaust hole are arranged in the air circuit connection block, and one end of the air intake channel is connected to an external air source device.

[0011] Furthermore, the air path connecting block is provided with an air nozzle joint connected to the air inlet channel.

[0012] Another object of the utility model is to provide a rapid hammering mechanism, which includes a component conveyor line, an X-axis transfer module located on the component conveyor line, a plurality of Y-axis transfer modules arranged on the X-axis transfer module for Y-axis transfer, a first support plate arranged at the movable end of the Y-axis transfer module, and the rapid hammering mechanism as described above arranged on the first support plate.

[0023] Embodiment 1:

[0024] Please refer to Figure 1-Figure 3 The present embodiment is a fast hammering mechanism 100, which includes an air circuit connection block 1, an air block 2 arranged on the lower surface of the air circuit connection block 1, a piston rod 3 horizontally slidably arranged in the air block 2, and a striking block 4 arranged at the end of the piston rod 3.

[0025] An air intake channel 11 and an air discharge channel 12 are provided in the air path connection block 1 , and one end of the air intake channel 11 is connected to an external air source device.

[0026] An air chamber 21 is provided in the air block 2, a piston block 31 is formed at one end of the piston rod 3 and extends into the air chamber 21 for horizontal movement, and the other end extends out of the air block 2, and the striking block 4 is installed at the other end of the piston rod 3; the air chamber 21 is divided into a first chamber 211 and a second chamber 212 distributed on the left and right by the piston block 31, and an air inlet hole 22 connecting the air inlet channel 11 and the second chamber 212 and an exhaust hole 23 connecting the air discharge channel 12 are provided on the air block 2.

[0027] The piston rod 3 is provided with a first passage connecting the first chamber 211 and the second chamber 212 when the piston rod 3 is retracted, and a second passage connecting the first chamber 211 and the exhaust hole 23 when the piston rod 3 is extended. The piston rod 3 is provided with a plurality of gas paths, including a first gas path 32 extending axially inward from the end of the piston block 31, a second gas path 33 and a third gas path 34 extending from the first gas path 32 to the outer peripheral surface of the piston rod 3, and the second gas path 33 and the third gas path 34 are distributed axially along the first gas path 32; the first gas path 32 and the second gas path 33 constitute the first passage, and the first gas path 32 and the third gas path 34 constitute the second passage. Under the condition of continuous inflation, the intake channel 11 realizes the left and right reciprocating motion of the piston rod 3 by alternately connecting with the first chamber 211 and the second chamber 212.

[0028] The second gas path 33 and the third gas path 34 extend radially upward from the first gas path 32 to the outer peripheral surface of the piston rod 3, and may also extend obliquely outward from the first gas path 32 to the outer peripheral surface of the piston rod 3, which is not limited in this embodiment; in addition, the first gas path 32 may be arranged to extend axially parallel to the piston rod 3, or may extend from left to right at an angle to the axis of the piston rod 3.

[0029] The axial distance between the second gas path 33 and the third gas path 34 is smaller than the corresponding distance between the air inlet hole 22 and the air outlet hole 23 .

[0030] In this embodiment, in order to facilitate manufacturing and installation, a stepped shaft hole penetrating the left and right surfaces is provided in the gas block 2, a section of the shaft hole with a large inner diameter forms the air chamber 21, and a section of the shaft hole with a small inner diameter forms a guide limit hole for the left and right movement of the piston rod 3. A cover plate 5 is provided at the left end of the gas block 2, and the cover plate 5 is sealed and connected to the gas block 2 through a sealing ring.

[0031] The gas circuit connection block 1 is provided with a gas nozzle joint 13 connected to the gas inlet passage 11 .

[0032] In this embodiment, since the entire hammering mechanism needs to be horizontally transferred by a horizontal transfer mechanism, the air path connecting block 1 and the air block 2 are set as two independent block structures. In other embodiments, the air path connecting block 1 may not be required, and an air intake channel may be directly formed at the air intake hole 22 on the air block 2, and an air discharge channel may be formed at the air exhaust hole 23.

[0033] When the piston rod 3 is in the retracted state, the first chamber 211 is squeezed and shrunk. At this time, the air intake channel 11 is connected with the second chamber 212 through the air intake hole 22. At the same time, the second chamber 212 is connected with the first chamber 211 through the second air path 33 and the first air path 32, while the third air path 34 is misaligned and blocked with the air discharge channel 12; when the air intake channel 11 is inflated, the air pressure enters the first chamber 211 through the second chamber 212, thereby pushing the piston rod 3 to move rightward and extend out; during the movement of the piston rod 3 to the right, the first chamber 211 gradually becomes larger, and the second chamber 212 is gradually squeezed and becomes smaller. When the second air path 33 moves axially out of the second chamber 212 and is misaligned and blocked with the second chamber 212, at this time, the third air path 34 is aligned with the air discharge channel 12 to guide The first chamber 211 and the second chamber 212 are connected because the second air path 33 is blocked. The air inlet channel 11 always maintains communication with the second chamber 212 through the air inlet hole 22. The air inlet channel 11 continues to be inflated, and the air pressure entering the second chamber 212 is expanded. Since the first chamber 211 is connected with the deflation channel 12 through the first air path 32, the third air path 34 and the exhaust hole 23, the first chamber 211 can be quickly squeezed to deflate, thereby pushing the piston rod 3 to move left and retract. When the piston rod 3 moves left to the initial retracted state, completing a cycle of telescopic movement, the air inlet channel 11 continues to be inflated, and the piston rod 3 will enter the next cycle of telescopic movement, thereby realizing high-frequency and rapid left and right reciprocating movement.

[0034] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
