Description

Technical Field

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

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

[0006] A needle pressing feeding mechanism comprises a feeding part, a fixed seat, a sliding seat, a sliding seat driving part and a supporting part, wherein:

[0007] The feeding part is used to transport the pressing needle to the feeding port along the first horizontal direction;

[0008] A conveying channel extending in a vertical direction is formed in the fixing seat;

[0009] The sliding seat is slidably connected to the fixed seat and is drivingly connected to the sliding seat driving unit arranged on the fixed seat. A material receiving groove arranged in the vertical direction is arranged at the edge of the sliding seat. The sliding seat driving unit is used to drive the sliding seat to translate along the second horizontal direction, so that the sliding seat can translate and switch between the material receiving position and the material dropping position, wherein the second horizontal direction is perpendicular to the first horizontal direction;

[0010] The support portion is arranged on the sliding seat;

[0011] When the sliding seat driving part drives the sliding seat to translate to the material receiving position, the material receiving groove docks with the material feeding port to receive the pressing needle output from the material feeding port, and the supporting part is configured to extend to support the needle cap of the pressing needle received by the material receiving groove, so that the pressing needle is kept in the material receiving groove;

[0012] When the sliding seat driving part drives the sliding seat to translate along the second horizontal direction to the blanking position, the receiving groove docks with the conveying channel, and the supporting part is configured to withdraw to release the pressing needle so that the pressing needle falls into the conveying channel.

[0013] In the press needle feeding mechanism of the utility model, the sliding seat can be moved relative to the fixed seat to realize the position switching between the material receiving position and the material blanking position. When the sliding seat moves to the material receiving position, the material receiving trough on it docks with the feeding port of the feeding part, so as to obtain the press needle supplied by the feeding part; when the sliding seat moves to the material blanking position, the material receiving trough on it docks with the conveying channel on the fixed seat, and the press needle falls into the conveying channel and is conveyed to the back-end. In addition, by providing a support part, the press needle can be limited in the material receiving trough during the movement to ensure that the press needle finally falls into the conveying channel. The press needle feeding mechanism of the utility model can automatically supply the press needle to the press needle installation mechanism of the back-end, so that the press needle installation mechanism can automatically install the press needle into the press needle hole of the press needle tooling to improve the assembly efficiency of the press needle tooling and save labor costs.

[0014] In some embodiments, the feeding part includes a vibrating plate and a conveying block, wherein: a conveying channel extending along a first horizontal direction and having a predetermined width is formed in the conveying block, one end of the conveying channel is connected to the discharge port of the vibrating plate, and the other end of the conveying channel constitutes the feeding port; the vibrating plate is used to buffer the pressing needles, and to convey the pressing needles one by one through the conveying channel to the feeding port through vibration, wherein the needle caps of the pressing needles are supported at the edges of both sides of the conveying channel.

[0015] Through the cooperation of the vibrating plate and the conveying block, the feeding part can output the pressing needles one by one through the conveying channel to the feeding port, thereby ensuring that the receiving groove on the sliding seat can receive a pressing needle from the feeding port each time and send the received pressing needle to the conveying channel.

[0016] In some embodiments, a cover plate covering the delivery channel is disposed above the delivery block, and a distance between the cover plate and an upper surface of the delivery block is greater than a thickness of the needle cap and less than twice the thickness of the needle cap.

[0017] By arranging a cover plate covering the conveying channel above the conveying block and setting the distance between the cover plate and the upper surface of the conveying block, it is possible to prevent the needle caps of two adjacent pressing needles from overlapping and affecting the normal conveying of the pressing needles in the conveying channel.

[0018] In some embodiments, the installation spacing between the cover plate and the upper surface of the conveying block is adjustable.

[0019] The delivery block is made compatible with press needles having needle caps of different thicknesses.

[0020] In some embodiments, the support portion includes a driving member and a support plate, wherein the driving member is mounted on a sliding seat, the support plate is connected to a movable part of the driving member, and a U-shaped notch is formed on the support plate at a position corresponding to the material receiving slot; the driving member is used to drive the support plate to translate along a first horizontal direction so that the support plate can translate and switch between a supporting position and a release position; when the driving member drives the support plate to translate to the supporting position, the support plate extends so that the edge of the U-shaped notch supports the needle cap of the pressing needle entering the material receiving slot; when the driving member drives the support plate to move to the release position, the support plate is withdrawn to release the needle cap of the pressing needle.

[0021] Before the receiving trough is connected with the feeding port, the driving member drives the support plate to move horizontally to the supporting position, so that when the pressing needle enters the receiving trough, the needle cap of the pressing needle can be supported at the edge of the U-shaped notch, thereby ensuring that the pressing needle is limited in the receiving trough. When the sliding seat slides to the material dropping position, the driving member drives the support plate to withdraw from the receiving trough, and the needle cap of the pressing needle loses support and falls into the conveying channel.

[0022] In some embodiments, the pressure needle feeding mechanism also includes a limit block arranged on the fixed seat, and the limit block is located on the outside of the sliding seat; when the sliding seat driving part drives the sliding seat to move to the blanking position, the limit block presses against the pressure needle in the receiving groove from the outside.

[0023] By setting a limit stopper, the pressing needle in the material receiving groove is limited from the outside, preventing the pressing needle from detaching from the material receiving groove from the outside when the sliding seat moves from the material receiving position to the material dropping position.

[0024] In some embodiments, a blowing joint connected to the delivery channel is passed through the fixing seat, and the blowing joint is used to blow air into the delivery channel to push the pressure needle of the delivery channel downward.

[0025] The air blowing joint blows air to the conveying channel, thereby pushing the pressing needle of the conveying channel to be conveyed downward, thereby preventing the pressing needle of the conveying channel from being stuck during the downward conveying process.

[0026] In some embodiments, a first guide opening with a diameter gradually decreasing from top to bottom is formed at the upper end of the delivery channel.

[0027] By arranging the first guide opening at the upper end of the conveying channel, the pressing needle is guided to ensure that the pressing needle in the material receiving trough falls smoothly into the conveying channel.

[0028] In some embodiments, an output connector is connected to the lower end of the delivery channel, an output channel connected to the delivery channel is formed in the output connector, and a second guide port with a diameter gradually decreasing from top to bottom is formed at the upper end of the output channel.

[0029] By setting a second guide port at the upper end of the output channel in the output connector, the pressure needle is guided to ensure that the pressure needle in the delivery channel falls smoothly into the delivery output channel, and enters the subsequent delivery pipeline through the output channel, and finally enters the pressure needle installation mechanism.

[0030] 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 tooling. The press needle installation device includes the press needle feeding mechanism, the press needle delivery pipeline and the press needle installation mechanism described in any of the above items, wherein: one end of the press needle delivery pipeline is connected to the delivery channel, and the other end of the press needle delivery pipeline is connected to the press needle installation mechanism; the press needle feeding mechanism supplies the press needle to the press needle installation mechanism via the press needle delivery pipeline; the press needle installation mechanism is used to install the press needle into the press needle hole of the press needle tooling.

[0031] Through the cooperation of the press needle feeding mechanism, the press needle conveying pipeline and the press needle installation mechanism, the press needle installation device 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.

[0059] 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.

[0060] 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 into the needle pressing hole of the needle pressing tool. Since each needle pressing tool needs to be installed with a large number of elastic needles, the manual installation method is inefficient.

[0061] In view of this, the utility model provides a press needle feeding mechanism, which can automatically supply the press needles to the subsequent press needle installation mechanism, so that the press needle installation mechanism can automatically install the press needles into the press needle holes of the press needle tooling, so as to improve the assembly efficiency of the press needle tooling and save labor costs.

[0062] like Figures 1 to 7 As shown, the pressure needle feeding mechanism 10 in the embodiment of the utility model includes a feeding part 1, a fixed seat 2, a sliding seat 3, a sliding seat driving part 4 and a supporting part 5, wherein:

[0063] The feeding part 1 is used to transport the pressing needle 100 to the feeding port along a first horizontal direction (eg, the X-axis direction in the figure).

[0064] A conveying channel 21 extending in the vertical direction is formed in the fixing base 2 .

[0065] The sliding seat 3 is slidably connected to the fixed seat 2 and is transmission-connected to the sliding seat driving unit 4 arranged on the fixed seat 2. A material receiving groove 31 arranged along the vertical direction is arranged at the edge of the sliding seat 3. The sliding seat driving unit 4 is used to drive the sliding seat 3 to translate along the second horizontal direction (for example, the Y-axis direction in the figure) so that the sliding seat 3 can translate and switch between the material receiving position and the material dropping position, wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0066] The support portion 5 is disposed on the sliding seat 3 .

[0067] When the sliding seat driving part 4 drives the sliding seat 3 to translate to the material receiving position, the material receiving groove 31 docks with the material feeding port to receive the pressing needle 100 output from the material feeding port, and the supporting part 5 is configured to extend to support the needle cap 101 of the pressing needle 100 received by the material receiving groove 31, so that the pressing needle remains in the material receiving groove 31;

[0068] When the sliding seat driving part 4 drives the sliding seat 3 to translate along the second horizontal direction to the blanking position, the receiving groove 31 docks with the conveying channel 21, and the supporting part 5 is configured to withdraw to release the pressing needle 100, so that the pressing needle 100 falls into the conveying channel 21.

[0069] The optional working process of the needle pressing and feeding mechanism 10 in the embodiment of the utility model is as follows:

[0070] First, the sliding seat driving part 4 drives the sliding seat 3 to translate to the material receiving position, so that the material receiving groove 31 on the sliding seat 3 is docked with the material feeding port of the material feeding part 1, and in addition, the supporting part 5 is controlled to extend.

[0071] A pressing needle 100 outputted from the feeding port of the feeding part 1 enters into the receiving groove 31 , and the needle cap 101 of the pressing needle 100 is supported on the supporting part 5 .

[0072] Then, if Figure 7As shown, the sliding seat driving unit 4 drives the sliding seat 3 to translate to the material dropping position, so that the material receiving groove 31 on the sliding seat 3 and the conveying channel 21 on the fixed seat 2 are connected with each other up and down.

[0073] Subsequently, the support part 5 is controlled to be withdrawn to release the pressing needle 100 , the needle cap 101 of the pressing needle 100 loses support, and the pressing needle 100 falls from the receiving groove 31 into the conveying channel 21 , and is finally supplied to the subsequent pressing needle installation mechanism.

[0074] The slide seat driving part 4 in the embodiment of the utility model can adopt various types of existing linear driving modules such as cylinders, screw motors, etc.

[0075] like Figure 1 and Figure 3 As shown, optionally, the feeding part 1 includes a vibration plate 11 and a conveying block 12, wherein: a conveying channel 121 extending along the first horizontal direction and having a predetermined width is formed in the conveying block 12, one end of the conveying channel 121 is connected to the discharge port of the vibration plate 11, and the other end of the conveying channel 121 constitutes the feeding port. The vibration plate 11 is used to buffer the pressing needles 100, and to convey the pressing needles 100 one by one to the feeding port through the conveying channel 121 by vibration, wherein the needle caps 101 of the pressing needles 100 are supported at the edges of both sides of the conveying channel 121.

[0076] It can be seen that through the cooperation of the vibration plate 111 and the conveying block 112, the feeding part 11 can output the pressing needles 100 one by one to the feeding port through the conveying channel 121, thereby ensuring that the receiving groove 31 on the sliding seat 3 can receive a pressing needle 100 from the feeding port each time and send the received pressing needle 100 to the conveying channel 21.

[0077] like Figure 3 As shown, optionally, the width of the conveying channel 121 is set to be slightly larger than the diameter of the thickest part of the needle body 102 of the pressing needle 100, and smaller than the diameter of the needle cap 101 of the pressing needle 100. In this way, it can be ensured that the needle body 102 of the pressing needle 100 can enter the conveying channel 121, and the needle cap 101 of the pressing needle 100 is supported at the edges of both sides of the conveying channel 121, so that the pressing needle 100 can be stably conveyed along the conveying channel 121 toward the feed port.

[0078] like Figure 2 and Figure 3 As shown, optionally, a cover plate 13 covering the conveying channel 121 is provided above the conveying block 12. In particular, the spacing H between the cover plate 13 and the upper surface of the conveying block 12 is greater than the thickness h of the needle cap 101 and less than twice the thickness h of the needle cap. This arrangement can prevent the needle caps 101 of two adjacent pressing needles conveyed front and back from overlapping, thereby affecting the normal conveyance of the pressing needle 100 in the conveying channel 121.

[0079] In order to achieve compatibility with the press needles 100 having needle caps 101 of different thicknesses, the installation spacing between the cover plate 13 and the upper surface of the conveying block 12 is optionally adjustable. For example, the cover plate 13 is movably mounted on the conveying block 12 via a plurality of vertical guide rods, and the installation spacing between the cover plate 13 and the upper surface of the conveying block 12 can be adjusted by controlling the cover plate 13 to be lifted along the vertical guide rods.

[0080] like Figures 4 to 8 As shown, optionally, the support portion 5 includes a driving member 51 and a support plate 52, wherein the driving member 51 is mounted on the sliding seat 3, the support plate 52 is connected to the movable part of the driving member 51, and a U-shaped notch is formed at the position of the support plate 51 corresponding to the material receiving slot 31. The driving member 51 is used to drive the support plate 52 to translate along the first horizontal direction, so that the support plate 52 translates and switches between the supporting position and the release position. When the driving member 51 drives the support plate 52 to translate to the supporting position, the support plate 52 extends out so that the edge of the U-shaped notch supports the needle cap 101 of the pressing needle 100 entering the material receiving slot 31. When the driving member 51 drives the support plate 52 to move to the release position, the support plate 52 is withdrawn to release the needle cap 101 of the pressing needle 100.

[0081] Before the receiving slot 31 is connected to the feeding port, the driving member 51 drives the supporting plate 52 to translate to the supporting position, so that when the pressing needle 100 enters the receiving slot 31, the needle cap of the pressing needle 101 is supported at the edge of the U-shaped notch of the supporting plate 52, thereby ensuring that the pressing needle 100 is limited in the receiving slot 31. When the sliding seat 3 slides to the material dropping position, the driving member 51 drives the supporting plate 52 to withdraw from the receiving slot 31, and the needle cap 101 of the pressing needle 100 loses the support of the U-shaped notch and falls into the conveying channel 21.

[0082] The driving member 51 can be a cylinder, a screw motor or other existing linear driving modules of various types.

[0083] like Figure 4 and Figure 5 As shown, optionally, the pressure needle feeding mechanism 10 in the embodiment of the utility model further includes a limit stopper 6 arranged on the fixed seat 2, and the limit stopper 6 is located on the outside of the sliding seat 3. In the process of the sliding seat driving unit 4 driving the sliding seat 3 to translate to the blanking position, the limit stopper 6 abuts against the pressure needle 100 in the receiving groove 31 from the outside, so that the pressure needle 100 is separated from the receiving groove 31 from the outside.

[0084] In some embodiments, a blowing joint connected to the delivery channel is passed through the fixing seat, and the blowing joint is used to blow air into the delivery channel to push the pressure needle of the delivery channel downward.

[0085] The air blowing joint blows air to the conveying channel, thereby pushing the pressing needle of the conveying channel to be conveyed downward, thereby preventing the pressing needle of the conveying channel from being stuck during the downward conveying process.

[0086] like Figure 7 As shown, optionally, the fixed seat 2 is connected with a blowing connector 22 connected to the conveying channel 21, and the blowing connector 22 is used to blow air into the conveying channel 21 to push the pressing needle 100 that falls into the conveying channel 21 to be conveyed downward to prevent the pressing needle 100 from getting stuck during the downward conveyance process.

[0087] Optionally, a first guide opening 23 with a diameter gradually decreasing from top to bottom is formed at the upper end of the conveying channel 21. By providing the first guide opening 23 at the upper end of the conveying channel 21, the pressing needle 100 is guided, thereby ensuring that the pressing needle 100 in the receiving trough 31 falls smoothly into the conveying channel 21.

[0088] Optionally, the lower end of the delivery channel 21 is connected with an output connector 7, an output channel 71 connected with the delivery channel 21 is formed in the output connector 7, and a second guide opening 72 with a diameter gradually reduced from top to bottom is formed at the upper end of the output channel 71. By providing the second guide opening 72 at the upper end of the output channel 71, the pressure needle is guided to ensure that the pressure needle 100 in the delivery channel 21 falls smoothly into the delivery output channel 71.

[0089] The pressing needle 100 that falls into the delivery output channel 71 is finally supplied to the subsequent pressing needle installation mechanism through the delivery pipeline connected to the output connector 7 .

[0090] 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. Fig. 9 As shown, the pressing needle installation device in the embodiment of the utility model comprises a pressing needle feeding mechanism 10, a pressing needle delivery pipeline 20 and a pressing needle installation mechanism 30 provided in any of the above embodiments, wherein: one end of the pressing needle delivery pipeline 20 is connected to the delivery channel 21, and the other end of the pressing needle delivery pipeline 20 is connected to the pressing needle installation mechanism 30. The pressing needle feeding mechanism 10 supplies the pressing needle 100 to the pressing needle installation mechanism 30 through the pressing needle delivery pipeline 20. The pressing needle installation mechanism 30 is used to install the pressing needle into the pressing needle hole of the pressing needle tooling.

[0091] It can be seen that through the cooperation of the press needle feeding mechanism 10, the press needle conveying pipeline 20 and the press needle installation mechanism 30, 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.

[0092] Continue to refer Fig. 9As shown, optionally, the press needle installation device in the embodiment of the utility model also includes a transfer mechanism 40, which transports the press needle tooling on which the press needle is to be installed to an installation station located below the press needle installation mechanism 30, and the press needle installation mechanism 30 installs the press needle on the press needle tooling located at the installation station.

[0093] 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.
