Description

Technical Field

[0001] The utility model relates to the field of photovoltaic cell production, in particular to a spring feeding mechanism and a spring mounting 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 of the needle pressing tool. Since each needle pressing tool needs to be installed with a large number of elastic needle pressing pins, the manual installation method is inefficient. Utility Model Content

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

[0006] A spring feeding mechanism comprises: a feeding part, a blowing part and a movable seat, wherein:

[0007] The material outlet of the feeding part and the air outlet of the air blowing part are arranged side by side above the movable seat;

[0008] An output channel arranged in a vertical direction is formed in the movable seat, and the movable seat is configured to be able to translate between a material receiving position and an air blowing position;

[0009] When the movable seat is translated to the material receiving position, the upper end of the output channel is docked with the discharge port of the feeding part, and the output channel receives the spring supplied by the feeding part;

[0010] When the movable seat is translated to the blowing position, the upper end of the output channel is butted against the blowing port of the blowing part, and the blowing part blows air into the output channel to promote the spring in the output channel to be transported.

[0011] The spring feeding mechanism of the utility model has a movable seat that can move back and forth between the discharge port of the feeding part and the blowing port of the blowing part. When the movable seat moves below the discharge port of the feeding part, it obtains the spring supplied by the feeding part; when the movable seat moves below the blowing port of the blowing part, the blowing part blows air toward the spring in the movable seat, so that the spring in the movable seat is transported to the back-end. It can be seen that through the cooperation of the movable seat, the feeding part and the blowing part, the spring feeding mechanism provided by the utility model can automatically supply the spring to the spring installation mechanism of the back-end, so that the spring installation mechanism can automatically install the spring into the pressing pin hole of the pressing pin tooling, so as to improve the assembly efficiency of the pressing pin tooling and save labor costs.

[0012] In some embodiments, the feeding part includes a feeding unit, a fixed seat and a blocking unit, wherein: a guide hole extending in a vertical direction is provided in the fixed seat, the upper end of the guide hole is connected to the feeding unit, and is used to receive the spring supplied by the feeding unit, and the lower end of the guide hole constitutes a discharge port of the feeding part; the blocking unit includes a driving member and a blocking member connected to the driving end of the driving member, and the driving member is used to drive the blocking member to translate between a blocking position and a discharge position; when the blocking member translates to the blocking position, the blocking member at least partially penetrates into the guide hole to block the spring in the guide hole; when the blocking member translates to the discharge position, the blocking member withdraws from the guide hole to allow the spring in the guide hole to fall into the output channel.

[0013] By providing a guide hole extending in the vertical direction in the fixed seat, the spring supplied by the feeding unit is dropped into the output channel in the vertical direction, so that the movable seat can transport the spring to the back channel. By providing a blocking unit, when the spring located at the bottom of the guide hole falls into the output channel, the blocking unit can block other springs in the guide hole, so that the springs can fall into the output channel one by one and be transported to the back channel, and finally the spring installation mechanism can install the springs one by one into the pressing needle hole of the pressing needle tooling.

[0014] In some embodiments, the blocking member includes a spring ejector pin, a top end of the spring ejector pin is formed with a pressing surface, and the spring ejector pin presses the spring in the guide hole through the pressing surface to block the spring.

[0015] The spring ejector pin is used as a blocking member, and the spring can be pressed into the guide hole, thereby achieving blocking of the spring.

[0016] In some embodiments, the blocking member includes a cutting pin, which is inserted into a gap between two adjacent springs in the guide hole to block the spring located above.

[0017] By using a cutting needle as a blocking member, the cutting needle can be controlled to be inserted into a gap between two adjacent springs, thereby implementing support and blocking for the spring located above the cutting needle.

[0020] In some embodiments, a blowing slit with an open guide hole and extending in a vertical direction is provided on the fixing seat; the spring feeding mechanism also includes an air blowing pipe, which is used to blow air obliquely downward toward the guide hole through the blowing slit to push the spring in the guide hole downward.

[0021] The air blowing pipe blows air obliquely downward toward the guide hole through the air blowing slit, so that the spring in the guide hole can be smoothly transported downward through the guide hole and fall into the output channel, thereby preventing the spring from getting stuck during transportation.

[0022] In some embodiments, the blowing part includes an air block and an air inlet pipe, wherein: a blowing channel arranged along the vertical direction is formed in the air block, an air inlet joint for connecting to the air inlet pipe is provided at the upper end of the blowing channel, and the lower end of the blowing channel constitutes a blowing port of the blowing part.

[0023] The air inlet pipe supplies compressed gas into the air blowing channel via the air inlet joint, so that the air block can be blown downward toward the output channel via the air blowing port.

[0024] In some embodiments, a proximity sensor is also provided on the movable seat. When the movable seat translates the proximity sensor to the material receiving position, the proximity sensor is triggered by the spring in the feeding part to generate a proximity signal, and the movable seat translates to connect the upper end of the output channel with the discharge port of the feeding part.

[0052] 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.

[0053] 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 of the needle pressing tool. Since each needle pressing tool needs to be installed with a large number of elastic needle pressing pins, the manual installation method is inefficient.

[0054] In view of this, the utility model provides a spring feeding mechanism, which can automatically supply the spring to the subsequent spring installation mechanism, so that the spring installation mechanism can automatically install the spring into the press needle hole of the press needle tooling, so as to improve the assembly efficiency of the press needle tooling and save labor costs.

[0055] like Figures 1 to 5 As shown, the spring feeding mechanism 10 in the embodiment of the utility model comprises a feeding part 1, a blowing part 2 and a movable seat 3, wherein:

[0056] The material outlet of the material feeding part 1 and the air blowing port of the air blowing part 2 are arranged side by side above the movable seat 3 .

[0057] An output channel 31 arranged along the vertical direction is formed in the movable seat 3, and the movable seat 3 is configured to be able to translate between a material receiving position and an air blowing position.

[0058] When the movable seat 3 translates to the material receiving position, the upper end of the output channel 31 docks with the discharge port of the feeding part 1 , and the output channel 31 receives the spring 100 supplied by the feeding part 1 .

[0059] When the movable seat 3 is translated to the blowing position, the upper end of the output channel 31 is connected with the blowing port of the blowing part 2, and the blowing part 2 blows air to the output channel 31 to push the spring 100 in the output channel 31 for delivery.

[0060] The working process of the spring feeding mechanism 10 in the embodiment of the utility model is as follows:

[0061] First, the movable seat 3 is controlled to translate to the material receiving position, so that the upper end of the output channel 31 in the movable seat 3 is docked with the discharge port of the feeding part 1 .

[0062] After a spring 100 in the feeding part 1 falls into the output channel 31 , the movable seat 3 is controlled to translate to the blowing position so that the upper end of the output channel 31 is docked with the blowing port of the blowing part 2 .

[0063] Next, the blowing unit 2 blows air to the output channel 31, thereby pushing the spring 100 in the output channel 31 to be transported to the rear channel.

[0064] It can be seen that through the cooperation of the feeding part 1, the movable seat 3 and the blowing part 2, the spring feeding mechanism provided in the embodiment of the utility model can automatically supply the spring to the subsequent spring installation mechanism, so that the spring installation mechanism can automatically install the spring into the pressing needle hole of the pressing needle tooling, so as to improve the assembly efficiency of the pressing needle tooling and save labor costs.

[0065] like Figures 1 to 3 As shown, optionally, the feeding part 1 includes a feeding unit 11, a fixing seat 12 and a blocking unit 13, wherein: a guide hole 121 extending in a vertical direction is provided in the fixing seat 12, the upper end of the guide hole 121 is docked with the feeding unit 11, and is used to receive the spring 100 supplied by the feeding unit 11, and the lower end of the guide hole 121 constitutes the discharge port of the feeding part 1. The blocking unit 13 includes a driving member 131 and a blocking member 132 connected to the driving end of the driving member 131, and the driving member 131 is used to drive the blocking member 132 to translate between a blocking position and a discharge position. When the blocking member 132 translates to the blocking position, the blocking member 132 at least partially penetrates into the guide hole 121 to block the spring 100 in the guide hole 121. When the blocking member 132 translates to the discharge position, the blocking member 132 withdraws from the guide hole 121, so that the spring 100 in the guide hole 121 falls into the output channel 31.

[0066] By providing a guide hole 121 extending in the vertical direction in the fixed seat 12, the fixed seat 12 can drop the spring 100 supplied by the feeding unit 11 into the output channel 31 of the movable seat 3 in the vertical direction, so that the movable seat 3 can transport the spring to the back-end. By providing a blocking unit 13, when the spring 100 located at the bottom of the guide hole 121 falls into the output channel 31, the blocking unit 13 can block the other springs 10 in the guide hole 121, so that the springs 100 entering the guide hole 121 can fall into the output channel 31 one by one and be transported to the back-end, and finally the spring installation mechanism of the back-end can install the springs 100 one by one into the pressing needle hole of the pressing needle tooling.

[0067] The driving member 131 in the embodiment of the utility model can be a linear driving member such as a cylinder, a screw motor, etc.

[0068] As known to those skilled in the art, in some press needle fixtures, the spring wires of all springs thereon are of the same thickness. In some other press needle fixtures, the springs located in the middle of the press needle fixture are thick springs with thicker spring wires, while the springs installed at the two ends of the press needle fixture are thin springs with thinner spring wires.

[0069] Since the thick spring is not easily deformed after being radially compressed, in the case of installing the thick spring, the blocking member 132 is optionally a spring ejector pin installed on the driving end of the driving member 131, and a pressing surface is formed at the top of the spring ejector pin. When the driving member 131 drives the spring ejector pin to penetrate into the guide hole 121, the top of the blocking member 132 can press the thick spring in the guide hole 121 through the pressing surface, thereby blocking the thick spring.

[0070] Since the thin spring is easily deformed after being radially compressed, in the case of installing the thin spring, the blocking member 132 is optionally a cutting pin installed on the driving end of the driving member 131. When the driving member 131 drives the cutting pin to be inserted into the guide hole 121, the cutting pin is inserted into the gap between two adjacent thin springs to support and block the thin spring located above the cutting pin.

[0071] Optionally, the feeding unit 11 includes a vibration plate 111 and an output pipe 112, wherein one end of the output pipe 112 is connected to the discharge port of the vibration plate 111, and the other end of the output pipe 112 is connected to the upper end of the guide hole 121. The vibration plate 111 is used to buffer the springs, and output the springs 100 one by one through the output pipe 112 to the guide hole 121 by vibration.

[0072] like Figure 3 As shown, optionally, a blowing slit 122 is provided on the fixed seat 12, which opens the guide hole 121 and extends in the vertical direction. Correspondingly, the spring feeding mechanism 10 in the embodiment of the utility model further includes a blowing pipe 4, which is used to blow air obliquely downward toward the guide hole 121 through the blowing slit 122, thereby pushing the spring 100 in the guide hole 121 to be transported downward, so that the spring 100 in the guide hole 121 can be smoothly transported downward through the guide hole 121 and fall into the output channel 31 of the movable seat 3, thereby preventing the spring 100 from getting stuck during the transportation process.

[0073] like Figure 5 As shown, optionally, the blowing part 2 includes an air block 21 and an air inlet pipe, wherein: a blowing channel 22 arranged along the vertical direction is formed in the air block 21, an air inlet connector 23 for connecting to the air inlet pipe is provided at the upper end of the blowing channel 22, and the lower end of the blowing channel 22 constitutes a blowing port of the blowing part 2.

[0074] The air inlet pipe supplies compressed gas to the air blowing channel 22 via the air inlet joint 23 , so that the air block 21 can be blown obliquely downward toward the guide hole 121 via the air blowing port and the air blowing slit 122 .

[0075] like Figure 3 As shown, optionally, a proximity sensor 5 is also provided on the movable seat 3. When the movable seat 3 translates the proximity sensor 5 to the material receiving position, the proximity sensor 5 is triggered by the spring 100 in the feeding part 1 to generate a proximity signal, and the movable seat 3 translates to dock the upper end of the output channel 31 with the discharge port of the feeding part. In this way, it can be ensured that the output channel 31 on the movable seat 3 is accurately docked with the discharge port of the feeding part 1, and the feeding part 1 can supply the spring 100 to the output channel 31 in time, and finally ensure the installation rhythm of the spring.

[0076] Optionally, the spring feeding mechanism 10 in the embodiment of the utility model further comprises a translation driving mechanism 6 for driving the movable seat 3 to translate between the material receiving position and the air blowing position. The translation driving mechanism 6 can be a linear driving member such as a cylinder, a screw motor, etc.

[0077] The present invention also provides a spring installation device for installing the spring into the pin hole of the pin press tool. Figure 6 As shown, the spring installation device in the embodiment of the utility model comprises the spring feeding mechanism 10, the spring delivery pipe 20 and the spring installation mechanism 30 in any of the above embodiments, wherein: one end of the spring delivery pipe 20 is connected to the lower end of the output channel 31 of the movable seat 3, and the other end of the spring delivery pipe 20 is connected to the spring installation mechanism 30. The spring feeding mechanism 10 supplies the spring to the spring installation mechanism 30 through the spring delivery pipe 20. The spring installation mechanism 30 is used to install the spring into the pressing needle hole of the pressing needle tooling.

[0078] It can be seen that through the cooperation of the spring feeding mechanism 10, the spring conveying pipeline 20 and the spring installation mechanism 30, the spring installation device in the embodiment of the utility model can automatically install the spring into the pressing needle hole of the pressing needle tooling, thereby improving the assembly efficiency of the pressing needle tooling and saving labor costs.

[0079] Continue to refer Figure 6 As shown, optionally, the spring installation device in the embodiment of the utility model also includes a transfer mechanism 40, which transports the pressing needle tool 200 on which the spring is to be installed to an installation station located below the spring installation mechanism 30, and the spring installation mechanism 30 installs the spring on the pressing needle tool 200 located at the installation station.

[0080] The above description of the utility model is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the utility model should fall within the scope of protection of the utility model. The scope of protection claimed by the utility model is defined by the claims, not by the above description in the embodiments.
