Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cell production, in particular to a pressure needle installation mechanism and a pressure needle installation device. Background Art

[0002] The pin press tool is a commonly used tool in the battery string manufacturing equipment in photovoltaic modules. During the battery string manufacturing process, the pin press tool is used to fix the soldering tape on the battery cell or fix the battery cell.

[0003] The press pin tooling includes a tooling body and an elastic press pin plugged into the tooling body. The elastic press pin includes a press pin for contacting the solder strip or battery cell, and a spring for providing a contraction force. When the press pin tooling is moved to the surface of the battery cell to fix the solder strip on the surface of the battery cell, the spring is compressed and the end of the press pin contacts the solder strip on the surface of the battery cell, thereby fixing the solder strip on the surface of the battery cell. When the press pin tooling is removed from the surface of the battery cell, the spring automatically returns to a natural state without force.

[0004] In the prior art, the assembly of the needle pressing tool is usually done manually, where a worker sequentially inserts a spring and a needle pressing into the needle pressing hole of the tool body. Since each needle pressing tool needs to be installed with a large number of elastic needle pressing pins, the manual installation method is inefficient. Summary of the invention

[0005] In view of the above problems existing in the manual assembly of the press needle tooling, the utility model provides a press needle installation mechanism, and its detailed technical solution is as follows:

[0011] When the second clamping assembly is clamped, the first clamping assembly is opened, wherein the second clamping assembly clamps the first pressing pin that falls into the second clamping assembly from the guide hole, and the second pressing pin located above the first pressing pin in the guide hole falls into the first clamping assembly;

[0012] When the second clamping assembly is opened, the first clamping assembly is clamped, wherein the second clamping assembly releases the first pressing needle to install the first pressing needle on the pressing needle tooling, and the first clamping assembly clamps the second pressing needle.

[0013] In the press needle installation mechanism of the utility model, the guide sleeve continuously transports the press needle toward the first clamping assembly and the second clamping assembly through the guide hole. When the second clamping assembly installs the current press needle on the press needle tooling, the first clamping assembly blocks other press needles located above the current press needle, thereby ensuring that the press needles are installed on the press needle tooling one by one.

In addition, through the cooperation of the first clamping assembly and the second clamping assembly, it can be ensured that only the first pressing needle located at the bottom is installed in the pressing needle installation hole each time, preventing other pressing needles from falling with the first pressing needle.

[0017] Only one finger cylinder is required to realize synchronous reverse driving of the second clamping assembly and the first clamping assembly, that is, when one of the two is opened, the other is clamped, thereby reducing the cost of the driving assembly.

[0053] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0054] In the prior art, the assembly of the press needle tool is usually done manually, where a worker sequentially inserts a spring and a press needle into the press needle hole of the tool body. Since each press needle tool needs to be installed with a large number of elastic press needles, the manual installation method is inefficient.

[0055] In view of this, the utility model provides a press needle installation mechanism, which can automatically install the press needle into the press needle hole of the press needle tooling, thereby improving the assembly efficiency of the press needle tooling and saving labor costs.

[0056] like Figures 1 to 6 As shown, the needle pressing mechanism in the embodiment of the utility model includes a mounting bracket 1, a guide sleeve 2, a driving assembly 3, a first clamping assembly 4 and a second clamping assembly 5, wherein:

[0057] The guide sleeve 2 is mounted on the mounting bracket 1 . A guide hole 21 extending in a vertical direction is provided in the guide sleeve 2 . The guide hole 21 is used for conveying the pressure needle.

[0058] The fixed components of the drive assembly 3 are mounted on the mounting bracket 1 .

[0059] The first clamping assembly 4 is located below the guide sleeve 2, and the second clamping assembly 5 is located below the first clamping assembly 4. The driving unit 3 is used to drive the first clamping assembly 4 to clamp or open, and drive the second clamping assembly 5 to clamp or open.

[0060] When the second clamping assembly 5 is clamped, the first clamping assembly 4 is opened, wherein the second clamping assembly 5 clamps the first pressing needle 101 that falls into the second clamping assembly 5 from the guide hole, and the second pressing needle 102 located above the first pressing needle 101 in the guide hole 21 falls into the first clamping assembly 4.

[0061] When the second clamping assembly 5 is opened, the first clamping assembly 4 is clamped, wherein the second clamping assembly 5 releases the first pressing needle 101 to install the first pressing needle 101 on the pressing needle tooling, and the first clamping assembly 4 clamps the second pressing needle 102 .

[0062] The optional working process of the pressure needle installation mechanism in the embodiment of the utility model is:

[0063] First, the second clamping assembly 5 is controlled to clamp, and the first clamping assembly 4 is opened. Multiple pressing pins are sequentially fed from the upper end opening of the guide hole 21 into the guide hole 21 through a pressing pin feeding mechanism or manually, so that multiple pressing pins are cached in the guide hole 21, and multiple pressing pins are stacked in sequence along the vertical direction, and the pressing pin at the bottom (i.e., the first pressing pin 101) falls into the second clamping assembly 5 and is clamped in the second clamping assembly 5, and the second pressing pin 102 located above the first pressing pin 101 falls into the first clamping assembly 4.

[0064] The entire pressing needle installation mechanism is controlled to move so that the first pressing needle 101 clamped in the second clamping assembly 5 is aligned with a pressing needle hole on the pressing needle tooling.

[0065] Next, the second clamping assembly 5 is controlled to open so that the first pressing needle 101 falls into the pressing needle hole. At the same time, the first clamping assembly 4 is controlled to clamp the second pressing needle 102 to prevent the second pressing needle 102 from falling together with the first pressing needle 101.

[0066] After completing the installation of the first pressing needle 101, control the first clamping assembly 4 to open and the second clamping assembly 5 to clamp, so that the second pressing needle 102 falls into the second clamping assembly 5 and is fixed in the second clamping assembly 5. At the same time, another pressing needle located above the second pressing needle 102 falls into the first clamping assembly 4, ready to install the second pressing needle 102 into another pressing needle hole.

[0067] The above process is repeated until the pressure needles buffered in the guide hole 21 are exhausted, and then the pressure needles of the guide hole 21 are replenished.

[0068] The press needle installation mechanism in the embodiment of the utility model can cache multiple press needles, and the guide sleeve 2 can continuously transport the press needles toward the first clamping assembly 4 and the second clamping assembly 5 through the guide hole 21. In addition, when the second clamping assembly 5 installs the current press needle on the press needle tooling, the first clamping assembly 4 blocks other press needles located above the current press needle, thereby ensuring that the press needles are installed on the press needle tooling one by one.

[0069] It can be seen that the press needle installation mechanism in the embodiment of the utility model can automatically install the press needle into the press needle hole of the press needle tooling, thereby improving the assembly efficiency of the press needle tooling and saving labor costs.

[0070] like Figures 1 to 4 As shown, optionally, the first clamping assembly 4 includes a first clamp 41 and a second clamp 42 arranged in pairs, and a first clamping channel 43 communicating with the guide hole 21 is formed between the first clamp 41 and the second clamp 42. The second clamping assembly 5 includes a third clamp 51 and a fourth clamp 52 arranged in pairs, and a second clamping channel 53 communicating with the first clamping channel 43 is formed between the third clamp 51 and the fourth clamp 53.

[0071] The driving assembly 3 drives the third chuck 51 and the fourth chuck 52 to clamp together, and drives the first chuck 41 and the second chuck 42 to open, so that the third chuck 51 and the fourth chuck 52 clamp the first pressing needle 101 that falls from the first clamping channel 43 into the second clamping channel 43, and the second pressing needle 102 falls into the first clamping channel 43. The driving assembly 3 drives the third chuck 51 and the fourth chuck 52 to open, and drives the first chuck 41 and the second chuck 42 to clamp together, so that the third chuck 51 and the fourth chuck 52 release the first pressing needle 101, and the first chuck 41 and the second chuck 42 clamp the second pressing needle 102.

[0072] like Figure 2 , Figure 5 and Figure 6 As shown, optionally, the driving assembly 3 includes a finger cylinder 31 and a mounting base plate 32, wherein: the cylinder body of the finger cylinder 31 is mounted on the mounting bracket 1, the third clamp 51 and the fourth clamp 52 are connected to the driving end of the finger cylinder 31, and the finger cylinder 31 is used to drive the third clamp 51 and the fourth clamp 52 to clamp or open. A first waist hole 511 is provided on the end of the third clamp 51 away from the clamping end, and a second waist hole 521 is provided on the end of the fourth clamp 52 away from the clamping end. The mounting base plate 32 is fixedly connected to the bottom of the cylinder body of the finger cylinder 31, the middle part of the first clamp 41 and the middle part of the second clamp 42 are rotatably connected to the mounting base plate 32 via the first connecting shaft 6, the end of the first clamp 41 away from the clamping end is provided with a second connecting shaft 7, and the second connecting shaft 7 is inserted in the first waist hole 511, and the end of the second clamp 42 away from the clamping end is provided with a third connecting shaft 8, and the third connecting shaft 8 is inserted in the second waist hole 521.

[0073] With such arrangement, when the finger cylinder 31 drives the third clamp 51 and the fourth clamp 52, the third clamp 51 and the fourth clamp 52 press toward the middle against the second connecting shaft 7 and the third connecting shaft 8, so that the clamping end of the third clamp 51 and the clamping end of the fourth clamp 52 are opened. When the finger cylinder 31 drives the third clamp 51 and the fourth clamp 52 to open, the third clamp 51 and the fourth clamp 52 drive the second connecting shaft 7 and the third connecting shaft 8 to open to both sides, so that the clamping end of the third clamp 51 and the clamping end of the fourth clamp 52 are clamped together.

[0074] It can be seen that the second clamping assembly 5 and the first clamping assembly 4 realize reverse linkage under the drive of the finger cylinder 31. That is to say, in the embodiment of the utility model, only one finger cylinder is provided to realize synchronous reverse drive of the second clamping assembly and the first clamping assembly, that is, when one of the two is opened, the other is clamped, thereby reducing the driving cost.

[0075] like Figure 5As shown, optionally, the clamping end of the third clamp 51 and the clamping end of the fourth clamp 52 both extend in the vertical direction, and the thickness of the clamping end of the third clamp 51 and the clamping end of the fourth clamp 52 both tapers from top to bottom. By setting the clamping ends of the third clamp 51 and the fourth clamp 52 to be wide at the top and narrow at the bottom, the clamping ends of the third clamp 51 and the fourth clamp 52 can be as close to the pin hole on the pin tooling as possible, so that the pin can be accurately installed in the pin hole.

[0076] Continue to refer Figure 5 As shown, optionally, the third clamp 51 is provided with a first avoidance groove 512 located above the second clamping channel 53, and the first avoidance groove 512 is used to avoid the first clamp 41. The fourth clamp 52 is provided with a second avoidance groove 522 located above the second clamping channel 53, and the second avoidance groove 522 is used to avoid the second clamp 42. In this way, the clamping ends of the first clamp 41 and the second pressing head 42 extend into the first avoidance groove 512 and the second avoidance groove 522 respectively, and finally the first clamping channel 43 and the second clamping channel 53 are connected from top to bottom.

[0077] like Figure 6 As shown, optionally, the clamping end of the first clamp 41 and the clamping end of the second clamp 42 both extend in the horizontal direction, and the clamping end of the first clamp 41 and the clamping end of the second clamp 42 respectively extend into the first avoidance groove 512 and the second avoidance groove 522. Such a configuration can ensure that the clamping ends of the first clamp 41 and the second pressing head 42 can smoothly extend into the first avoidance groove 512 and the second avoidance groove 522, and make the upper and lower surfaces of the clamping end of the first clamp 41 close to the first avoidance groove 512, and the upper and lower surfaces of the clamping end of the second clamp 42 close to the second avoidance groove 522, and finally make the first clamping channel 43 and the second clamping channel 53 dock up and down.

[0078] Optionally, the mounting base plate 32 is a stepped structure, which includes a higher first mounting portion 321 and a lower second mounting portion 322, wherein the first mounting portion 321 is connected to the bottom of the cylinder body of the finger cylinder 31, and an installation gap is formed in the height direction between the second mounting portion 322 and the third chuck 51 and the fourth chuck 52, and the first chuck 41 and the second chuck 42 are arranged on the second mounting portion 322 and are located in the installation gap.

[0079] Optionally, the press needle installation mechanism in the embodiment of the utility model further includes a moving part, the installation bracket 1 is connected to the moving part, and the moving part is used to drive the installation bracket 1 to move, so as to drive the first clamping assembly 4 and the second clamping assembly 5 to move synchronously. By setting the moving part, the first clamping assembly 4 and the second clamping assembly 5 are driven, so that the first clamping assembly 4 and the second clamping assembly 5 cooperate with each other, and the press needles are sequentially installed in each press needle hole on the press needle tooling.

[0080] The utility model also provides a press needle installation device, which is used to install the press needle into the press needle hole of the press needle tool. Figure 7 As shown, the press needle installation device in the embodiment of the utility model includes a transfer mechanism 20, a press needle feeding mechanism 30 and the press needle installation mechanism 10 in any of the above embodiments, wherein: the transfer mechanism 20 is used to transport the press needle tooling to be installed with the press needle to the installation station. The press needle installation mechanism 10 is set at the installation station, the press needle feeding mechanism 30 is used to transport the press needle to the guide hole 21 of the press needle installation mechanism 10, and the press needle installation mechanism 10 is used to install the press needle on the press needle tooling located at the installation station. The transfer mechanism 20 is also used to transport the press needle tooling that has completed the press needle installation to the material receiving station located after the installation station.

[0081] Through the cooperation of the transfer mechanism 20, the press needle feeding mechanism 30 and the press needle installation mechanism 10, the press needle installation device in the embodiment of the utility model automatically installs the press needle into the press needle hole of the press needle tooling, thereby improving the assembly efficiency of the press needle tooling and saving labor costs.
