Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell string production, and in particular to a limiting ring installation device. Background Art

[0002] During the battery string production process, in order to keep the battery cells and the soldering ribbons relatively fixed to avoid the soldering ribbons from shifting, a soldering ribbon pressing tool is required to press the soldering ribbons onto the battery cells one by one. Figure 1 The solder strip pressing tool shown in the figure is taken as an example, which includes a tool frame 100 and multiple press needle groups. Each press needle group corresponds to pressing a solder strip. Each press needle group includes multiple press needles 9 arranged at intervals along the X direction. The press needles 9 are connected to the through holes of the tool frame 100. The upper ends of the press needles 9 are longitudinally limited by the limit ring 8 to prevent the press needles 9 from escaping from the tool frame 100 (Note: Figure 1 The two rows of press pins 9 arranged along the Y direction near the edge of the tooling frame 100 have not yet been installed with the limiting rings 8. During the assembly process of the tooling frame and the press pins, it is necessary to install a limiting ring on each press pin, and finally squeeze the limiting ring to deform it, thereby limiting the press pin on the tooling frame.

[0003] Typically, installing a retaining ring on each press pin requires a worker to use a handheld clamp or other tool to pick up the retaining rings one by one and then fit them onto the corresponding press pin. However, due to the large number of press pins and the small size of the retaining rings, this method of picking up and installing the retaining rings one by one is not only inefficient but also consumes a lot of labor costs. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a limit ring installation device to improve the installation efficiency of the limit ring.

[0005] The present application provides a limiting ring installation device, which is used to install a limiting ring on a pressure needle. The limiting ring installation device includes: a mounting head and a material rack, wherein:

[0006] A first flow channel is provided in the material rack along the length direction of the material rack, and the first flow channel is used to store and transport a row of limit rings;

[0007] The mounting head includes a first chuck, a second chuck, and an elastic component. The first chuck and the second chuck are respectively rotatably connected to the first end of the material rack. A second flow channel connected to the first flow channel is formed between the first chuck and the second chuck. The second flow channel is used to receive the limit ring flowing into the first flow channel and transfer the limit ring toward the head of the first chuck and the second chuck.

[0008] A side of the bottom of the second flow channel close to the first clamp and the head of the second clamp is provided with an avoidance groove for the pressure needle to pass through;

[0009] The first chuck and the second chuck are pressed against each other via an elastic component to buffer a limiting ring located in the second flow channel;

[0010] When subjected to external force, the heads of the first clamp and the second clamp rotate relative to the material rack and move away from each other, thereby releasing a limiting ring close to the heads of the first clamp and the second clamp.

[0011] When installing the limit ring using this limit ring installation device, it is only necessary to load the limit ring into the material rack, and the material rack can continuously transport the limit ring to the installation head. At this time, align the limit ring at the installation head with the pressure needle, make the pressure needle pass through the avoidance groove to hook the limit ring, and move the limit ring installation device. Since the limit ring is blocked by the pressure needle and cannot move with the limit ring installation device, the two clamps will open outward under the extrusion force of the limit ring, and the limit ring can be detached from between the two clamps and then installed on the pressure needle, completing the installation of the first limit ring; after the limit ring is detached, the two clamps will automatically close under the action of the elastic component to prevent the adjacent limit ring from detaching from the installation head. When the limit ring installation device moves to the next pressure needle, the same method is used to align the limit ring at the installation head with the pressure needle and move the limit ring installation device, so as to achieve the installation of the second limit ring, and so on. Since multiple limit rings can be added and stored in the material rack at one time, when the limit ring installation device is continuously moved along the arrangement direction of the pressure pins to be installed with the limit rings, multiple limit rings can be installed continuously. Compared with the traditional technology, where workers clamp and install the limit rings one by one, the installation efficiency of the limit rings is greatly improved, and the labor cost required for the installation of the limit rings is reduced.

[0012] In some embodiments, the heads of the first chuck and the second chuck respectively extend inward to form a blocking portion; when the first chuck and the second chuck are close to each other, the distance between the two blocking portions is less than the width of the limiting ring to limit the limiting ring from sliding out from between the heads of the first chuck and the second chuck; when the first chuck and the second chuck are away from each other, the distance between the two blocking portions is greater than or equal to the width of the limiting ring to release a limiting ring close to the heads of the first chuck and the second chuck.

[0013] In the above embodiment, a blocking portion is provided. When the first chuck and the second chuck are close to each other, the distance between the two blocking portions is smaller than the width of the limiting ring, that is, the blocking portion can block the limiting ring when the limiting ring is not installed to prevent the limiting ring from falling off; when the first chuck and the second chuck are far away from each other, the distance between the two blocking portions is greater than or equal to the width of the limiting ring, that is, the blocking portion can release the limiting ring when the limiting ring is installed.

[0014] In some embodiments, an extended bottom plate extending along the length direction of the material rack is provided at the outlet of the first flow channel corresponding to the first end of the material rack, and the upper surface of the extended bottom plate is flush with the bottom surface of the first flow channel; a receiving groove for the extended bottom plate to extend into is formed between the first chuck and the second chuck; the receiving groove and the extended bottom plate together enclose to form the second flow channel.

[0015] In the above embodiment, between the first chuck and the second chuck, the accommodating groove and the extended bottom plate together enclose a second flow channel. The second flow channel can receive the limiting ring from the first flow channel. The limiting ring is temporarily stored in the second flow channel. When the limiting ring is installed, the limiting ring can be directly released from the second flow channel, which increases the convenience of installing the limiting ring.

[0016] In some embodiments, the avoidance groove is provided at one end of the extended bottom plate close to the blocking portion, and the pressing needle can pass through the avoidance groove and hook the limiting ring abutting against the blocking portion.

[0017] In the above embodiment, the limiting ring at the installation head can be aligned with the pressure needle, so that the pressure needle passes through the avoidance groove to hook the limiting ring, and the limiting ring installation device is moved. Since the limiting ring is obstructed by the pressure needle and cannot move with the limiting ring installation device, the two clamps will open outward under the squeezing force of the limiting ring, and the limiting ring can be detached from the blocking part between the two clamps and installed on the pressure needle, further increasing the convenience of the installation of the limiting ring.

[0018] In some embodiments, the limiting ring installation device further includes a feeding bin; the feeding bin is installed at the second end of the material rack, the feeding bin is used to receive and store the limiting ring, and the first flow channel is connected to the feeding bin.

[0019] In the above embodiment, a feeding bin is further provided at the second end of the material rack, and the feeding bin can receive and store the limit rings, that is, a large number of limit rings can be added to the feeding bin at one time, and the limit rings can be transported from the feeding bin to the first flow channel, and then to the second flow channel. In other words, by adding the limit rings to the feeding bin once, a large number of pressure pins can be installed with the limit rings, which greatly improves the installation efficiency of the limit rings.

[0020] In some embodiments, a first transition section is provided between the feeding bin and the first flow channel; the first end of the first transition section is connected to the feeding bin, and the second end of the first transition section is connected to the first flow channel, and the first transition section is used to receive the limit ring flowing in from the feeding bin and transmit the limit ring toward the first flow channel; the width of the limit ring allowed to pass through by the first transition section gradually decreases along the transmission direction of the limit ring.

[0021] In the above embodiment, the first transition section can receive the limit ring from the feeding bin, and the structure of the first transition section can regularize the limit ring and transport the regularized limit ring to the first flow channel. This structure can prevent the limit ring from directly flowing into the first flow channel from the feeding bin, thereby avoiding the limit ring from being blocked between the first flow channel and the feeding bin.

[0022] In some embodiments, the width of the second end of the first transition section allows two rows of limiting rings to pass side by side.

[0023] The above embodiment defines the width of the second end of the first transition section to allow two rows of limiting rings to pass side by side, that is, the first transition section can organize the limiting rings into two rows, thereby avoiding blockage of the limiting rings.

[0024] In some embodiments, a second transition section is further provided between the first transition section and the first flow channel; the first end of the second transition section is connected to the second end of the first transition section, and the second end of the second transition section is connected to the first flow channel, and the second transition section is used to receive the limit ring flowing in from the first transition section and transmit the limit ring toward the first flow channel; the width of the second transition section allowing the limit ring to pass through gradually decreases along the transmission direction of the limit ring, and the width of the first end of the second transition section is less than or equal to the width of the second end of the first transition section.

[0025] In the above embodiment, the second transition section can take over the two rows of limit rings from the first transition section, further regularize them, and transport the regularized limit rings to the first flow channel. The setting of the second transition section realizes further regularization of the limit rings and further reduces the possibility of blockage of the limit rings.

[0026] In some embodiments, the width of the second end of the second transition section allows a row of limiting rings to pass through.

[0027] The second transition section in the above embodiment can arrange the limit rings into a row, thereby transporting a row of limit rings to the first flow channel and then into the second flow channel, which is more convenient for the installation of the limit rings.

[0028] In some embodiments, a first cover plate is provided on the first transition section and the second transition section; the distance between the first cover plate and the bottom of the first transition section and the second transition section is greater than the height of a single limiting ring and less than the height of two limiting rings.

[0029] In the above embodiment, a first cover plate is provided on the first transition section and the second transition section, and the distance between the first cover plate and the bottom of the first transition section and the second transition section is greater than the height of a single limiting ring and less than the height of two limiting rings, so that the limiting ring can only pass through a single layer in the first transition section and the second transition section, avoiding the upper and lower stacking of the limiting ring, and further reducing the possibility of the limiting ring being blocked in the first transition section and the second transition section.

[0030] In some embodiments, the first cover is made of a transparent material.

[0031] In the above embodiment, the first cover plate is made of transparent material, so that the staff can see the condition of the limiting rings in the first transition section and the second transition section through the first cover plate, and see whether there is material or blockage.

[0032] In some embodiments, a second cover plate is provided on the material rack; a long waist hole extending along the length direction of the material rack is provided on the second cover plate; the long waist hole is provided corresponding to the first flow channel, and the width of the long waist hole is smaller than the width of the limiting ring.

[0033] In the above embodiment, the setting of the long waist hole allows the staff to see the situation of the limiting ring in the first flow channel on the material rack through the long waist hole, which is convenient for observing whether there is material in the material rack. Since the width of the long waist hole is smaller than the width of the limiting ring, the limiting ring can be prevented from falling off from the long waist hole.

[0034] In some embodiments, the limiting ring mounting device further includes a protective sleeve; the protective sleeve is mounted on the second end of the material rack.

[0035] In the above embodiment, a protective cover is provided, which can protect the worker's base of the thumb when the worker uses the limit ring installation device, thereby preventing the worker from being injured. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0045] The present application will be described in detail below through specific embodiments.

[0046] In some embodiments, as Figure 1-Figure 3 As shown, the limiting ring installation device is used to set the limiting ring on the pressure needle 9, and the limiting ring installation device includes: a mounting head 1 and a material rack 2, wherein: the material rack 1 is provided with a first flow channel 3 along the length direction of the material rack, and the first flow channel 3 is used to store and transport a row of limiting rings 8; the mounting head 1 includes a first clamp 4, a second clamp 5 and an elastic component (not shown in the figure), and the first clamp 4 and the second clamp 5 are respectively connected to the first end of the material rack 2 (for example Figure 2 The right end of the first chuck 4 and the second chuck 5 are rotatably connected, and a second flow channel 6 connected to the first flow channel 3 is formed between the first chuck 4 and the second chuck 5. The second flow channel 6 is used to receive the limit ring 8 flowing in from the first flow channel 3, and transmit the limit ring 8 toward the heads of the first chuck 4 and the second chuck 5; the bottom of the second flow channel 6 is close to the side of the heads of the first chuck 4 and the second chuck 5. An avoidance groove 7 for the pressure needle 9 to pass through is provided; the first chuck 4 and the second chuck 5 are pressed against each other by an elastic component to cache the limit ring 8 located in the second flow channel 6; when the heads of the first chuck 4 and the second chuck 5 are subjected to external force, they rotate relative to the material rack 2 and move away from each other to release a limit ring 8 close to the heads of the first chuck 4 and the second chuck 5.

[0047] Optionally, in some embodiments, the elastic component is an elastic rubber band that is tightly sleeved on the outside of the first clamp 4 and the second clamp 5 to keep the first clamp 4 and the second clamp 5 close to each other in a natural state. In other embodiments, the elastic component includes a tension spring, the first end of the tension spring is connected to the first clamp, and the second end of the tension spring is connected to the second clamp. The tension spring keeps the first clamp 4 and the second clamp 5 close to each other in a natural state.

[0048] The optional working process of the limit ring installation device of the embodiment of the present application is as follows:

[0049] A limiting ring 8 is added to the material rack 2. The worker holds the material rack 2 and shakes it, so that the limiting ring 8 in the material rack flows from the first flow channel 3 into the second flow channel 6 in the mounting head 1. The second flow channel 6 transmits the limiting ring 9 to the heads of the first chuck 4 and the second chuck 5. At this time, the first chuck 4 and the second chuck 5 are pressed against each other through the elastic component, and the limiting ring 8 is confined in the second flow channel 6.

[0050] Keep the rack 2 in an inclined state (as Figure 1 As shown in the figure), align the mounting head 1 with a pressing needle 9, and make the pressing needle 9 pass through the avoidance groove 7 and hook the limiting ring 8 in the second flow channel 6. At this time, move the limiting ring mounting device horizontally. The limiting ring 8 cannot move because it is hooked by the pressing needle 9. The first clamp 4 and the second clamp 5 will open outwards under the squeezing force of the limiting ring 8, and the limiting ring 8 can be detached from between the two clamps and then installed on the pressing needle 9, completing the installation of the first limiting ring 8. After the first limiting ring 8 is detached, the two clamps will automatically close under the action of the elastic component to prevent the second adjacent limiting ring 8 from detaching from the mounting head 1.

[0051] When the limiting ring installation device moves to the next pressing pin 9, the same method is used to align the second limiting ring 8 at the installation head with the pressing pin 9 and move the limiting ring installation device to achieve the installation of the second limiting ring 8. Similarly, the installation of multiple limiting rings 8 can be completed.

[0052] Since a plurality of limiting rings 8 can be added and stored in the rack 3 at one time, when the arrangement direction of the pressure pins 9 along the limiting rings 8 to be installed (such as Figure 1 When the limit ring installation device is continuously moved in the X direction or Y direction in the drawing, multiple limit rings 8 on a row of pressure pins can be continuously installed. Compared with the traditional technology in which workers clamp and install the limit rings 8 one by one, the installation efficiency of the limit rings 8 is greatly improved, and the labor cost required for the installation of the limit rings is reduced.

[0053] In some embodiments, as Figure 1-Figure 5 As shown, the heads of the first chuck 4 and the second chuck 5 extend inward to form a blocking portion 10; when the first chuck 4 and the second chuck 5 are close to each other, the distance between the two blocking portions 10 is less than the width of the limiting ring 8, so as to limit the limiting ring 8 from sliding out from between the heads of the first chuck 4 and the second chuck 5; when the first chuck 4 and the second chuck 5 are away from each other, the distance between the two blocking portions 10 is greater than or equal to the width of the limiting ring 8, so as to release a limiting ring 8 close to the heads of the first chuck 4 and the second chuck 5.

[0054] The optional working process of the limiting ring installation device of the embodiment of the present application is: when the limiting ring 8 does not need to be installed on the pressure needle 9, the first chuck 4 and the second chuck 5 are close to each other, and the distance between the two blocking parts 10 is smaller than the width of the limiting ring 8. The limiting ring 8 is restricted in the second flow channel 6 by the blocking part 10 and will not flow out; when the limiting ring 8 needs to be installed on the pressure needle 9, the pressure needle 9 can be passed through the avoidance groove 7 to hook the limiting ring 8 at the blocking part 10. At this time, the limiting ring installation device is moved, and the first chuck 4 and the second chuck 5 will be squeezed away from each other by the limiting ring 8. At this time, the distance between the two blocking parts 10 will gradually increase until the distance between the two blocking parts 10 is greater than or equal to the width of the limiting ring 8, and the limiting ring 8 will be released from the blocking part 10.

[0055] In some embodiments, as Figure 1-Figure 3 As shown, an extended bottom plate 11 extending along the length direction of the material rack 2 is provided at the outlet of the first flow channel 3 at the first end of the material rack 2, and the upper surface of the extended bottom plate 11 is flush with the bottom surface of the first flow channel 3; a receiving groove 12 for the extended bottom plate 11 to extend into is formed between the first clamp 4 and the second clamp 5; the receiving groove 12 and the extended bottom plate 11 together enclose a second flow channel 6.

[0056] Among them, the extended bottom plate 11 provides support for the limit ring 8 in the second flow channel 6, so that the limit ring 8 can flow from the first flow channel 3 to the blocking part 10, and the second flow channel 6 can receive the limit ring 8 from the first flow channel 3. The limit ring 8 is temporarily stored in the second flow channel 6. When the limit ring is installed, the limit ring 8 can be directly released from the second flow channel 6, which increases the convenience of installing the limit ring.

[0057] Optionally, the extended bottom plate 11 and the material rack 2 are integrally formed.

[0058] In some embodiments, as Figure 1-Figure 5 As shown, the avoidance groove 7 is provided at one end of the extended bottom plate 11 close to the blocking portion 10 , and the pressing needle 9 can pass through the avoidance groove 7 and hook the limiting ring 8 abutting against the blocking portion 10 .

[0059] In one possible embodiment, a semicircular notch, namely the avoidance groove 7, can be provided at one end of the extended base plate 11 close to the blocking portion 10. It should be noted that the size of the semicircular notch is smaller than the limiting ring 8. The pressing needle 9 can pass through the avoidance groove 7 and hook the limiting ring 8 abutting against the blocking portion 10, but the limiting ring 8 will not fall from the avoidance groove 7.

[0060] In some embodiments, as Figure 1-Figure 5 As shown, the limiting ring installation device also includes a feeding bin 19; the feeding bin 19 is installed at the second end of the rack 2 (for example Figure 2The left end of the figure), the feeding bin 19 is used to receive and store the limit ring 8, and the first flow channel 3 is connected to the feeding bin 19.

[0061] The optional working process of the limit ring installation device of the embodiment of the present application is: when the limit ring needs to be installed, a large number of limit rings 8 can be pre-loaded into the feeding bin 19, and the limit ring 8 can flow from the feeding bin 19 into the first flow channel 3, and then into the second flow channel 6, and finally reach the blocking part 10. At this time, the limit ring 8 can be installed on the pressure needle 9. Since a large number of limit rings 8 can be added to the feeding bin 19 at one time, that is, the limit ring 8 is added to the feeding bin 19 once, a large number of pressure needles 9 can be installed with the limit ring, which greatly improves the installation efficiency of the limit ring.

[0062] In some embodiments, as Figure 2 As shown, a first transition section 13 is provided between the feeding bin 19 and the first flow channel 3; the first end of the first transition section 13 is communicated with the feeding bin 19, and the second end of the first transition section 13 is communicated with the first flow channel 3, and the first transition section 13 is used to receive the limit ring 8 flowing in from the feeding bin 19 and transmit the limit ring 8 toward the first flow channel 3; the width of the first transition section 13 allowing the limit ring 8 to pass through gradually decreases along the transmission direction of the limit ring 8.

[0063] Since a large number of limit rings 8 are stored in the feeding bin 19, in order to facilitate the installation of the limit rings 8, the width of the first transition section 13 that allows the limit rings 8 to pass through gradually decreases along the transmission direction of the limit rings 8. This design can regularize the limit rings 8, for example, regularize them into rows of limit rings 8, which can prevent the limit rings 8 from directly flowing into the first flow channel 3 from the feeding bin 19, thereby avoiding blockage of the limit rings 8 between the first flow channel 3 and the feeding bin 19.

[0064] In some embodiments, the width of the second end of the first transition section 13 allows two rows of limiting rings to pass side by side.

[0065] The optional working process of the limit ring installation device of the embodiment of the present application is: the first transition section 13 receives the limit ring 8 from the feeding bin 19, and after the received limit ring 8 is arranged into two rows, it is transported to the first flow channel 3, so that the limit ring enters the first flow channel 3 in order, avoiding blockage of the limit ring 8.

[0066] In some embodiments, as Figure 2As shown, a second transition section 14 is further provided between the first transition section 13 and the first flow channel 3; the first end of the second transition section 14 is communicated with the second end of the first transition section 13, and the second end of the second transition section 14 is communicated with the first flow channel 3, and the second transition section 14 is used to receive the limit ring 8 flowing in from the first transition section 13, and transmit the limit ring 8 toward the first flow channel 3; the width of the second transition section 14 allowing the limit ring 8 to pass through gradually decreases along the transmission direction of the limit ring 8, and the width of the first end of the second transition section 14 is less than or equal to the width of the second end of the first transition section 13.

[0067] After the first transition section 13 arranges the limit rings 8 into two rows, the limit rings 8 may still be blocked. Therefore, a second transition section 14 is set between the first transition section 13 and the first flow channel 3. The first transition section 13 arranges the limit rings 8 into two rows and then transports them to the second transition section 14. The structure of the second transition section 14 can continue to arrange the two rows of limit rings 8, further reducing the possibility of blockage of the limit rings 8.

[0068] In some embodiments, the width of the second end of the second transition section 14 allows a row of limiting rings 8 to pass through.

[0069] The optional working process of the limit ring installation device of the embodiment of the present application is: the second transition section 14 can use its own structure to regularize the two rows of limit rings 8 delivered from the first transition section 13 into one row, and deliver one row of limit rings 8 to the first flow channel 3. Compared with two rows of limit rings 8, one row of limit rings 8 further reduces the possibility of blockage of the limit rings 8.

[0070] In some embodiments, as Figure 1 As shown, a first cover plate 15 is provided on the first transition section 13 and the second transition section 14 ; the distance between the first cover plate 15 and the bottom of the first transition section 13 and the second transition section 14 is greater than the height of a single limiting ring 8 and less than the height of two limiting rings 8 .

[0071] In one possible embodiment, the distance between the first cover plate 15 and the bottom of the first transition section 13 and the second transition section 14 can be 1.5 times the height of a single limiting ring 8. Under this design, the limiting ring 8 can not only flow smoothly through the first transition section 13 and the second transition section 14, but also prevent two layers of limiting rings 8 from being stacked together, further reducing the possibility of the limiting ring 8 being blocked in the first transition section 13 and the second transition section 14.

[0072] In some embodiments, the first cover plate 15 is made of a transparent material, so that the staff can see the conditions of the limiting rings 8 in the first transition section 13 and the second transition section 14 through the first cover plate 15 .

[0073] When the staff sees through the first cover plate 15 that the number of limit rings 8 in the first transition section 13 and the second transition section 14 is insufficient, the staff can add limit rings 8 to the feeding bin 19. In addition, when the limit rings cannot be installed smoothly, the staff can also check through the first cover plate 15 whether the limit rings 8 in the first transition section 13 and the second transition section 14 are blocked.

[0074] In some embodiments, as Figure 1 As shown, a second cover plate 16 is provided on the material rack 2; a long waist hole 17 extending along the length direction of the material rack 2 is provided on the second cover plate 16; the long waist hole 17 is provided corresponding to the first flow channel 3, and the width of the long waist hole 17 is smaller than the width of the limiting ring 8.

[0075] In one possible embodiment, the distance between the second cover plate 16 and the bottom of the material rack 2 can also be greater than the height of a single limit ring 8 and less than the height of two limit rings 8. The limit ring 8 can only pass through a single layer in the first flow channel 3, which greatly reduces the possibility of the limit ring 8 being blocked in the first flow channel 3. In addition, workers can see the condition of the limit ring 8 in the first flow channel 3 through the long waist hole 17. For example, when it is seen through the long waist hole 17 that the number of limit rings 8 in the first flow channel 3 is insufficient, it proves that the limit ring 8 needs to be replenished in the feeding bin 19. In addition, because the width of the long waist hole 17 is smaller than the width of the limit ring 8, it can be ensured that the limit ring 8 will not fall out of the long waist hole 17.

[0076] In some embodiments, as Figure 2 As shown, the limiting ring installation device also includes a protective sleeve 18; the protective sleeve 18 is installed at the second end of the material rack 2.
