In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] Such as Figures 1 to 6As shown in the figure, the utility model discloses a quick-change device for welding copper nozzles. The quick-change device for welding copper nozzles in this embodiment includes a fixed seat 100, a sliding seat 200 and a clamping member 300. The fixed seat 100 is used to be connected to the welding equipment 30. A sliding cavity 110 is provided on the fixed seat 100. A welding copper nozzle is arranged on the sliding seat 200. The sliding seat 200 is slidably arranged in the sliding cavity 110. A clamping groove 201 is provided on the sliding seat 200. The clamping member 300 is installed in the clamping hole 140. During the process of the sliding seat 200 sliding into the sliding cavity 110, the clamping member 300 can be clamped into the clamping groove 201. It can be understood that since the welding copper nozzle is integrated on the sliding seat 200, the welding copper nozzle can be a connecting piece welding copper nozzle 20 or an FPC welding copper nozzle 10, or other welding copper nozzles. In this way, the connecting piece welding copper nozzle 20 and the FPC welding copper nozzle 10 are integrated into two consistent structural modules. During the actual working process, when a certain welding copper nozzle is needed, the sliding seat 200 of the corresponding structural module is aligned with the sliding cavity 110, and the sliding seat 200 is slid into the sliding cavity 110. When the sliding seat 200 slides to the designated position, the clamping member 300 provided on the fixed seat 100 can be clamped into the clamping groove 201 of the sliding seat 200 to position it. When replacement is needed, only the sliding seat 200 fitted on the fixed seat 100 needs to be slid in the reverse direction to take it out and replace it with another structural module. Since the switching of the welding copper nozzle can be conveniently realized and no screws need to be disassembled during the operation process, the operation is simple and incorrect operation is not likely to occur, which is beneficial to improving the reflow soldering yield rate.

[0036] Reference Figure 2 As shown in the figure, at least one side wall of the sliding cavity 110 is provided with a sliding groove 120. The clamping member 300 is arranged on the groove wall of the sliding groove 120. The sliding seat 200 has a sliding part 210 that fits into the sliding groove 120. It can be understood that during the actual operation process, the sliding part 210 is aligned with the sliding groove 120, and then the sliding seat 200 is pushed to realize the sliding part 210 sliding into the sliding groove 120. During the sliding process, when the sliding part 210 slides to the position corresponding to the clamping groove 201 of the clamping hole 140, the clamping member 300 can be clamped into the clamping groove 201 to realize the positioning of the sliding seat 200. The provided sliding part 210 can facilitate the sliding of the sliding seat 200 relative to the fixed seat 100. The clamping member 300 arranged on the groove wall of the sliding groove 120 is beneficial to realizing the clamping and release of the sliding part 210. Preferably, sliding grooves 120 are provided on the two relatively arranged side walls of the sliding cavity 110. Compared with the structure with a single-sided sliding groove 120, the double-sided sliding grooves 120 are beneficial to improving the sliding stability and installation stability of the sliding seat 200, so as to ensure that the connecting piece welding copper nozzle 20 or the FPC welding copper nozzle 10 can be stably installed on the welding equipment 30 after the clamping is completed.

[0037] Optionally, there are multiple clamping members 300, which are arranged at intervals along the length direction of the sliding groove 120. It can be understood that clamping the sliding seat 200 by multiple clamping members 300 is beneficial to improving the installation stability of the sliding seat 200, so as to ensure that the connecting piece welding copper nozzle 20 or the FPC welding copper nozzle 10 can be stably installed on the welding device 30 after the clamping is completed. In this embodiment, two clamping members 300 are arranged in one sliding groove 120. Of course, in other embodiments of the present invention, the number of clamping holes 140 can also be set to three, four or even more according to actual needs.

[0038] Reference Figure 3 As shown, the fixing seat 100 is provided with a clamping hole 140. The clamping member 300 includes a plunger 310, a clamping head 320 and a first elastic member 330. The plunger 310 is installed in the clamping hole 140. The plunger 310 has an installation hole 311 with one end closed and the other end open. The clamping head 320 is installed at the open end of the installation hole 311. One end of the first elastic member 330 abuts against the closed end of the installation hole 311, and the other end abuts against the clamping head 320. It can be understood that during the actual working process, when the sliding part 210 slides in the sliding groove 120, when the sliding part 210 contacts the clamping head 320 and continues to drive the sliding part 210, the sliding part 210 can drive the clamping head 320 to move towards the closed end of the installation hole 311, so that the first elastic member 330 is compressed. When the sliding part 210 moves to the position where the clamping groove 201 and the clamping hole 140 are correspondingly arranged, the clamping head 320 can move towards the open end of the installation hole 311 under the elastic force of the first elastic member 330, and at least partially extend out of the installation hole 311 to be clamped into the clamping groove 201, so as to complete the clamping of the sliding seat 200. When it is necessary to replace the welding copper nozzle, only need to pull the sliding part 210 in the reverse direction, and the clamping head 320 can gradually slide out of the clamping groove 201, so as to release the clamping of the sliding part 210. Forming the clamping member 300 by the plunger 310, the clamping head 320 and the first elastic member 330 can not only facilitate the clamping of the sliding part 210, but also facilitate the release of the clamping of the sliding part 210, which is beneficial to the installation and disassembly of the sliding seat 200.

[0039] Optionally, the side of the card connector 320 facing away from the first elastic member 330 is formed as an arc surface, and the card slot 201 is formed as an arc-shaped slot. According to the foregoing, whether during the process of engaging the sliding seat 200 or releasing the engagement of the sliding seat 200, the card connector 320 will slide relative to the card slot 201. The side of the card connector 320 facing away from the first elastic member 330 is formed as an arc surface, and the card slot 201 is formed as an arc-shaped slot, which is conducive to the card connector 320 sliding into and out of the card slot 201, so that it is both convenient to engage the sliding part 210 and to release the engagement of the sliding part 210, which is conducive to the installation and disassembly of the sliding seat 200. Further optionally, the card connector 320 is a steel ball, and the card slot 201 is a hemispherical slot.

[0040] It should be added that the card connector 300 is formed as an elastic plunger structure composed of a plunger 310, a card connector 320 and a first elastic member 330. This elastic plunger structure can be a standard part, such as a spring ball head plunger, etc., and can be directly obtained by outsourcing, so there is no need to manufacture it separately, which is conducive to reducing the manufacturing cost of the entire welding copper nozzle quick-change device.

[0041] It should be additionally noted that in other embodiments of the present invention, the form of the card connector 300 can also be set to other structures according to actual needs, and is not limited to the above description. For example, in an alternative embodiment, the card connector 300 is formed as an elastic protrusion adhered to the inner wall of the sliding groove 120. During the sliding process, the sliding part 210 presses the elastic protrusion to cause it to deform. When the sliding part 210 slides to the position corresponding to the card slot 201 of the card hole 140, the elastic protrusion resumes its original shape and can be snapped into the card slot 201, thereby realizing the positioning of the sliding seat 200. When replacing the welding copper nozzle, only need to pull the sliding seat 200 in the reverse direction, the card connector 300 gradually slides out of the card slot 201 and is re-pressed, and the sliding seat 200 can be smoothly taken out from the fixed seat 100.

[0042] Such as Figures 4 - 5As shown, the fixing base 100 is further provided with a locking hole which communicates with the sliding groove 120. The extending direction of the locking hole is arranged at an angle with the sliding direction of the sliding seat 200. The welding copper nozzle quick-change device further includes a locking member 400 which is installed in the locking hole and can abut against the side wall of the sliding portion 210 to lock the sliding seat 200. It can be understood that when the sliding portion 210 slides to the position where the clamping groove 201 corresponds to the clamping hole 140, the clamping member 300 can be inserted into the clamping groove 201 to position the sliding seat 200. If there is a huge external force or other unexpected situations, the sliding seat 200 may accidentally slide out of the fixing base 100. In this embodiment, the locking member 400 is added. When the sliding portion 210 slides to the position where the clamping groove 201 corresponds to the clamping hole 140, the clamping member 300 can be inserted into the clamping groove 201. The locking member 400 is adjusted to abut against the sliding seat 200 to lock the sliding seat 200. In this way, under the combined action of the clamping member 300 and the locking member 400, it can be ensured that the sliding seat 200 is stably held on the fixing base 100, avoiding the phenomenon that the sliding seat 200 accidentally slides out of the fixing base 100, so as to ensure that the connecting piece welding copper nozzle 20 or the FPC welding copper nozzle 10 can be stably installed on the welding device 30 after the clamping is completed.

[0043] Optionally, the locking member 400 is any one of a locking screw, a rotary plunger or a positioning pin.

[0044] Optionally, referring to Figure 6 As shown, a first wear-resistant member 220 is provided on the side wall of the sliding seat 200, and the first wear-resistant member 220 has a locking hole 221 which cooperates with the locking member 400. It can be understood that during the actual working process, the locking member 400 needs to abut against the sliding portion 210 to play a role in locking the sliding seat 200. After long-term use, it is possible to wear out a concave pit on the sliding seat 200, resulting in a decrease in the locking ability. In this embodiment, the first wear-resistant member 220 is added. The first wear-resistant member 220 is installed on the side wall of the sliding portion 210 and has a locking hole 221 which cooperates with the locking member 400. When the locking member 400 is inserted into the locking hole 221, it can lock the sliding seat 200. Due to the existence of the first wear-resistant member 220, the sliding seat 200 will not be worn after long-term use. If there is a problem with the first wear-resistant member 220, the first wear-resistant member 220 can be directly replaced, which is beneficial to extending the service life of the sliding seat 200.

[0045] Optionally, the first wear-resistant member 220 is detachably connected to the sliding portion 210 by means of connecting screws, snap connections, etc. Thus, it is convenient for the user to replace the first wear-resistant member 220.

[0046] Referring to Figure 6As shown, a second wear-resistant member 230 is provided on the sliding portion 210. The second wear-resistant member 230 is clamped between the inner wall of the sliding groove 120 and the sliding portion 210, and the clamping groove 201 is provided on the second wear-resistant member 230. During the actual working process, the clamping member 300 needs to be inserted into the clamping groove 201 to lock the sliding seat 200. After long-term use, the clamping groove 201 may be worn and become larger, resulting in a decrease in the locking ability. At this time, the entire sliding portion 210 needs to be replaced, increasing the cost. In this embodiment, a second wear-resistant member 230 is added, and the clamping groove 201 is provided on the second wear-resistant member 230. When the locking member 400 is inserted into the locking hole 221, the sliding seat 200 can be locked. After long-term use, when the clamping groove 201 is worn and becomes larger, resulting in a decrease in the locking ability, only a second wear-resistant member 230 needs to be replaced, which is beneficial to extending the service life of the sliding seat 200.

[0047] Optionally, the second wear-resistant member 230 is detachably connected to the sliding portion 210 by means of connection screws, snap connections, etc. Thus, it is convenient for users to replace the second wear-resistant member 230.

[0048] Reference Figures 4 - 5 As shown, the welding copper nozzle quick-change device further includes a position detection member 500. The position detection member 500 is installed on the fixed seat 100 and is used to detect the position of the sliding seat 200. It can be understood that since the welding copper nozzle is integrated on the sliding seat 200, if the sliding seat 200 slides and deviates relative to the fixed seat 100 after clamping, it will directly cause welding deviation. In this embodiment, by adding a position detection member 500 to detect the position of the sliding seat 200, when the sliding seat 200 deviates, the operator can be reminded in time to adjust the sliding seat 200, reducing the probability of welding deviation, which is beneficial to improving the re-welding yield.

[0049] Optionally, the fixed seat 100 has a detection hole communicating with the sliding cavity 110; the position detection member 500 includes a mounting seat 510 and a position sensor 520. The mounting seat 510 is connected to the fixed seat 100, and the position sensor 520 is installed on the mounting seat 510 and extends into the test hole 130. It can be understood that the position sensor 520 is installed on the mounting seat 510 and extends into the test hole 130, and the position sensor 520 can detect the distance between its end and the surface of the sliding seat 200. Once the distance changes after clamping, it means that the sliding seat 200 has an accidental slide, so the operator can be reminded in time to adjust the sliding seat 200, reducing the probability of welding deviation, which is beneficial to improving the re-welding yield. Of course, in other embodiments of the present invention, the position detection member 500 can also be selected as other types according to actual needs, such as an infrared rangefinder, etc.

[0050] The sliding seat 200 is provided with equal-height studs 240 and a second elastic member 250. One end of each equal-height stud 240 is connected to the connecting piece welding nozzle 20 or the FPC welding nozzle 10 by welding. The second elastic member 250 is sleeved on the equal-height stud 240, and both ends of the second elastic member 250 abut against the sliding seat 200 and the welding nozzle respectively. It can be understood that during the actual working process, the welding nozzle is arranged downward to perform welding. When the welding device 30 drives the welding nozzle to move downward and the welding nozzle contacts the component to be welded, the second elastic member 250 can play a buffering role to avoid hard impact between the welding nozzle and the component to be welded, thereby being beneficial to protecting the welding nozzle.

[0051] A handle 260 is provided on the sliding seat 200. The added handle 260 facilitates the operator to push or pull out the sliding seat 200, thus facilitating the installation and replacement of the sliding seat 200.

[0052] The following describes the specific working process of this welding nozzle quick-change device. For the convenience of description, it is described by taking the example that the welding device 30 first uses the connecting piece welding nozzle 20 and then uses the FPC welding nozzle 10;

[0053] Install the fixed seat 100 on the welding device 30;

[0054] Align the two sliding parts 210 on the sliding seat 200 equipped with the connecting piece welding nozzle 20 with the two sliding grooves 120 on the fixed seat 100 respectively. Hold the handle 260 and push the sliding seat 200 in. When the clamping head 320 can be clamped into the clamping groove 201 and makes a sound, it can be considered that the sliding seat 200 has slid to the designated position;

[0055] Rotate the locking member 400 on the fixed seat 100 to lock the sliding seat 200, so as to connect the connecting piece welding nozzle 20 to the welding device 30;

[0056] After the connecting piece repair welding is completed, rotate the locking member 400 on the fixed seat 100 to release the sliding seat 200, and pull the sliding seat 200 to make it slide out of the fixed seat 100;

[0057] Align the two sliding parts 210 on the sliding seat 200 equipped with the FPC welding nozzle 10 with the two sliding grooves 120 on the fixed seat 100 respectively. Hold the handle 260 and push the sliding seat 200 in. When the clamping head 320 can be clamped into the clamping groove 201 and makes a sound, it can be considered that the sliding seat 200 has slid to the designated position;

[0058] Rotate the locking member 400 on the fixed seat 100 to lock the sliding seat 200, so as to connect the FPC welding nozzle 10 to the welding device 30.
