[0039] See also Figure 1-Figure 7 A dispensing auxiliary fixing fixture for a connector includes a base 100, a first clamping member 200 and a second clamping member 300. The first clamping member 200 is movably arranged on the base 100. The first clamping member 200 can move along a first direction and enclose a clamping space 110 for clamping and fixing the connector with the base 100. The first clamping member 200 is provided with a first constraint portion 210, and the second clamping member 300 is provided with a second constraint portion 310. The second clamping member 300 is movably connected to the first clamping member 200. The second clamping member 300 can move along a second direction so that the first constraint portion 210 and the second constraint portion 310 enclose a dispensing port 400. The dispensing port 400 is used to constrain the line of the connector and accommodate glue. The first direction and the second direction are arranged to intersect.
[0040] In this embodiment, if Figure 1 , 2As shown, the first direction is the vertical direction, i.e., the Z-axis direction, and the second direction is the Y-axis direction. The first clamping member 200 may be a rectangular plate-shaped structure, and one side end of the first clamping member 200 is movably connected to the base 100. The first clamping member 200 and one end surface of the base 100 are arranged opposite to each other, and the end surface is arranged below the first clamping member 200 in the vertical direction. Therefore, the space between the first clamping member 200 and the end surface forms a clamping space 110. In addition, a first constraint portion 110 is arranged on the first clamping member 200. 210, the second clamping member 300 can also be a rectangular plate-shaped structure, the second clamping member 300 can move in the second direction and be connected with the first clamping member 200, wherein the second clamping member 300 is provided with a second constraint portion 310, when the second clamping member 300 moves to the first position in the second direction, the first clamping member 200 and the second clamping member 300 cooperate to form a clamping state, at this time, the first constraint portion 210 and the second constraint portion 310 cooperate to form a dispensing port 400 for dispensing operations. Specifically, when in use, the circular connector is placed in the clamping space 110 between the first clamping frame and the base 100 in the vertical direction, the bottom end of the circular connector is in contact with the end surface of the base 100, and one end of the PIN pin on the circular connector is the top end, and then the first clamping member 200 is moved in the vertical direction according to the height of the circular connector, so that the first clamping member 200 and the top end of the circular connector are in contact, so that the first clamping member 200 and the base 100 clamp and fix the circular connector, and at this time, the part of the PIN pin welding wire corresponds to the first constraint portion 210 of the first clamping member 200, and then the second clamping member 300 is moved in the second direction, so that the second clamping member 300 is moved to the first direction. In one position, the first constraint portion 210 and the second constraint portion 310 cooperate to form a glue dispensing port 400, and the wires soldered on the circular connector are passed through the glue dispensing port 400 and kept in a vertical state, so that the solder joints of the PIN needles are exposed on the glue dispensing port 400. Then, a glue dispensing gun is used to inject AB glue into the glue dispensing port 400, and the glue dispensing port 400 is filled so that the AB glue completely covers the solder joints. Then, the glue dispensing port 400 is left to stand for about 20 minutes to wait for the AB glue to completely solidify. Then, the second clamping member 300 is moved along the second direction to separate the glue dispensing port 400 and no longer constrain the wires. Then, the first clamping member 200 is moved in the opposite direction along the first direction to keep the first clamping member 200 away from the circular connector, and the circular connector is removed to complete the glue dispensing work.
[0041] In the above structure, by movably setting the first clamping member 200 on the base 100, and making the first clamping member 200 and the base 100 cooperate to clamp and fix the circular connector, it is effectively avoided that in the existing manual clamping method, the circular connector is easily offset due to unstable holding before the glue is initially solidified, and then the AB glue is tilted and the welding point is not completely wrapped. The stability of the circular connector during glue dispensing is ensured, and the labor cost is also reduced. In addition, the second clamping member 300 and the first clamping member 200 are movably matched to form a glue dispensing port 400, so as to realize the constraint of the wire and the mold effect when the welding point is dispensed, which effectively replaces the method of manually rotating the connector to adjust the glue dispensing angle during glue dispensing. When injecting glue, the AB glue is filled into the glue dispensing port 400 to ensure the complete wrapping of the welding point, and the insulation protection of the welding point is realized, which further improves the efficiency of the glue dispensing work.
[0042] In the specific structure of the base 100, the base 100 includes a bottom plate 120 and a side plate 130 connected to each other, a first clamping member 200 is movably arranged on the side plate 130, and the first clamping member 200 is arranged opposite to the bottom plate 120, and the first clamping member 200 can move along the first direction on the side plate 130 and enclose a clamping space 110 with the bottom plate 120. A plurality of first restraining portions 210 are arranged on the first clamping member 200, and the plurality of first restraining portions 210 are arranged at equal intervals along the third direction, and a plurality of second restraining portions 310 are correspondingly arranged on the second clamping member 300. The first direction, the second direction and the third direction are arranged perpendicular to each other.
[0043] In this embodiment, if Figure 1 , 34, the third direction is the X-axis direction, the base 100 includes a bottom plate 120 and a side plate 130, the bottom plate 120 and the side plate 130 are both rectangular plate structures, the bottom plate 120 is horizontally placed on the working platform, the side plate 130 is placed in the vertical direction, and the bottom end of the side plate 130 is connected to one end of the bottom plate 120, one end of the first clamping member 200 is connected to the side plate 130, the first clamping member 200 is arranged opposite to the bottom plate 120, the first clamping member 200 moves along the first direction to enclose the clamping space 110 with the bottom plate 120, and the bottom plate 120, the side plate 130, the first clamping member 200, and the second clamping member 300 all extend along the third direction, that is, the third direction is the length direction of each. A plurality of first constraint portions 210 are evenly arranged on the first clamping member 200 along its length direction, and correspondingly, a plurality of second constraint portions 310 are evenly arranged on the second clamping member 300 along its length direction. When the first clamping member 200 and the second clamping member 300 are matched and connected, a plurality of dispensing ports 400 are formed, thereby facilitating the dispensing of multiple circular connectors at the same time, and further improving the dispensing efficiency. For example, in this embodiment, ten first constraint portions 210 are arranged on the first clamping member 200, and correspondingly, ten second constraint portions 310 are also arranged on the second clamping member 300, and ten dispensing ports 400 are formed when the first clamping member 200 and the second clamping member 300 are matched. In addition, the bottom plate 120 and the side plate 130 can be connected by bolts or the like, which is convenient for installation and disassembly.
[0044] In the moving structure of the first clamping member 200 on the side plate 130, the fixture also includes a locking bolt 500, which includes a stud 510 and a nut 520 connected to each other. The side plate 130 is provided with a guide groove 131 extending along the first direction. The diameter of the nut 520 is larger than the opening size of the guide groove 131. The stud 510 passes through the guide groove 131 and is movably connected to the first clamping member 200, and is at least used to lock the movement of the first clamping member 200 in the first direction.
[0045] In this embodiment, a threaded hole is provided on one side end of the first clamping member 200, and a guide groove 131 is provided at a corresponding position of the side plate 130. The guide groove 131 extends along a first direction. The first clamping member 200 and the side plate 130 are movably connected by a locking bolt 500. When installing, the first clamping member 200 is first placed in a horizontal direction and one end thereof is abutted against the side plate 130 so that the threaded hole corresponds to the guide groove 131. Then, the stud 510 of the locking bolt 500 is passed through the guide groove 131 from the other side of the side plate 130 to match the threaded hole. The nut 520 is now separated from the side plate 130, so that when the first clamping member 200 moves along the first direction, the stud 510 moves in the guide groove 131, guiding and limiting the movement of the first clamping member 200, improving the stability of the movement of the first clamping member 200, and when the first clamping member 200 needs to be locked, because the diameter of the nut 520 is larger than the width of the guide groove 131, the stud 510 is further inserted into the threaded hole, so that the nut 520 abuts against the side plate 130, thereby locking the first clamping member 200. The locking structure is simple, easy to operate, and can effectively improve the operating efficiency.
[0046] Specifically, there are multiple locking bolts 500, and the multiple locking bolts 500 are evenly connected to the first clamping member 200 along the third direction, and multiple guide grooves 131 are provided at corresponding positions of the side plate 130. Since the first clamping member 200 extends along the third direction, and the first clamping member 200 is provided with multiple first restraining portions 210 along the third direction, in order to improve the stability of the movement or fixation of the first clamping member 200, multiple locking bolts 500 are connected to the first clamping member 200 along the third direction, i.e., the length direction thereof, and correspondingly, multiple guide grooves 131 are also provided at positions on the side plate 130 corresponding to the locking bolts 500.
[0047] In addition, a limiting groove 121 is provided on an end surface of the bottom plate 120 opposite to the first clamping member 200 . The limiting groove 121 is used to at least accommodate a portion of the connector.
[0048] In this embodiment, if Figure 5As shown, when clamping the circular connector, the first clamping member 200 and the bottom plate 120 are clamped and fixed along the vertical direction, that is, the height direction of the circular connector. In order to avoid relative sliding between the bottom of the circular connector and the bottom plate 120 during the dispensing process, which causes the circular connector to tilt and thus affects the dispensing effect, a limiting groove 121 is provided on the bottom plate 120. The limiting groove 121 can be a circular groove-shaped structure, and the diameter of the limiting groove 121 is consistent with the bottom diameter of the circular connector. When clamping the circular connector, the bottom of the circular connector is placed in the limiting groove 121, which can effectively limit the movement of the circular connector on the bottom plate 120. At the same time, according to the different diameters of the circular connectors to be dispensed, a suitable bottom plate 120 with a corresponding diameter limiting groove 121 can be selected to improve applicability.
[0049] In addition, a limiting column 122 extending along the first direction is provided in the limiting groove 121, and the limiting column 122 can extend into the opening of the connector. In other embodiments, some circular connectors have openings at the bottom. In order to further limit the circular connector, a limiting column 122 extending along the first direction is provided in the limiting groove 121. When the circular stopper is clamped, the limiting column 122 can be extended from the opening at the bottom of the circular connector into the interior of the circular connector to improve the limiting effect.
[0050] The base 100 further includes a cable tie plate 140, which is connected to the side plate 130, and the cable tie plate 140 and the bottom plate 120 are arranged opposite to each other, and the first clamping member is movably arranged between the cable tie plate 140 and the bottom plate 120, and the cable tie plate 140 is provided with a cable tie groove 141, which is arranged opposite to the glue dispensing port 400 to constrain the wires of the connector. The cable tie groove 141 is a "U"-shaped groove structure, and the opening of the cable tie groove 141 is arranged at the outer edge of the cable tie plate 140.
[0051] In this embodiment, the base 100 is provided with a cable tie plate 140, which is a rectangular plate-shaped structure. The cable tie plate 140 is placed in a horizontal direction, one end of the cable tie plate 140 is connected to the top of the side plate 130, and is arranged opposite to the bottom plate 120. The first clamping member 200 is connected between the cable tie plate 140 and the bottom plate 120. The cable tie plate 140 also extends along the third direction, wherein a cable tie groove 141 is provided at a position corresponding to the dispensing port 400 on the cable tie plate 140. When the circular connector is clamped between the first clamping member 200 and After the base plate 120 is connected, the welded wires are first passed through the glue dispensing port 400 and kept in a vertical state, and then the wires are passed through the wire harness trough 141 located above the first clamp 200. The wire harness trough 141 constrains the wires. Since multiple wires will be welded on the circular connector, a wire harness trough 141 is provided on the wire harness plate 140 above the first clamp 200 to effectively prevent the wires from bending due to gravity during the glue dispensing work, thereby blocking the glue dispensing port 400 or affecting the line of sight of the glue dispensing operator, thereby affecting the glue dispensing effect. Specifically, the wire harness trough 141 is a "U"-shaped groove structure, and the opening of the wire harness trough 141 is provided at the edge of the wire harness plate 140, so that the wire harness trough 141 is a through-groove structure formed by being recessed inwardly along the second direction from the edge of the wire harness plate 140, thereby facilitating the wires to pass through the opening.
[0052] In the specific structure of the first clamping member 200 and the second clamping member 300, the first clamping member 200 is provided with a first surface 220 and a second surface 230 opposite to each other, the first surface 220 is movably connected to the base 100, and the second surface 230 is provided with an arc-shaped opening recessed toward the first surface 220 to form a first constraint portion 210, and the second clamping member 300 is provided with a third surface 320 and a fourth surface 330 opposite to each other, and the third surface 320 is provided with an arc-shaped opening recessed toward the fourth surface 330 to form a second constraint portion 310. When the first clamping member 200 and the second clamping member 300 are connected in cooperation, the second surface 230 and the third surface 320 are in contact with each other, and the first constraint portion 210 and the second constraint portion 310 surround the glue dispensing port 400.
[0053] In this embodiment, the first clamping member 200 and the second clamping member 300 are both rectangular structures, and the two side surfaces of the first clamping member 200 along the second direction of its width direction are respectively a first surface 220 and a second surface 230, wherein the first surface 220 is connected to the side plate 130, specifically, a threaded hole is opened on the first surface 220, and a first constraint portion 210 is arranged on the second surface 230, wherein the first constraint portion 210 is an arc-shaped groove structure formed by being recessed inwardly from the second surface 230 along its own width direction, and is a through structure in the first direction of the height direction of the first clamping member 200, similarly, the second clamping member 300 is respectively provided with a third surface 320 and a fourth surface 330 on the two side surfaces along the second direction of its width direction, wherein a second constraint portion 310 is arranged on the third surface 320, wherein the second constraint portion 310 is an arc-shaped groove structure formed by being recessed inwardly from the third surface 320 along its own width direction, and is a through structure in the first direction of the height direction of the second clamping member 300. Among them, the notch size of the first constraint part 210 is consistent with the notch size of the second constraint part 310. When the first clamping member 200 and the second clamping member 300 are matched and connected, the third surface 320 and the second surface 230 are fitted, so that the first constraint part 210 and the second constraint part 310 are opposite to each other and together form a circular dispensing port 400. The dispensing port 400 is set as a split structure. First, it is easy to detach the circular connector after dispensing. In addition, the circular dispensing port 400 can effectively ensure the uniformity of dispensing and control the amount of glue dispensed on each connector to reduce the occurrence of defective products. At the same time, the dispensing port 400 is enclosed by the first clamping member 200 and the second clamping member 300, which further improves the applicability of the fixture and can effectively adapt to the circular connectors with different numbers of wires to be welded. In addition, the first clamping member 200 and the second clamping member 300 are made of Teflon material, wherein the surfaces of the first constraint portion 210 and the second constraint portion 310 are processed very smoothly, so that when the circular connector is removed after the dispensing is completed, no residual glue is left on the surfaces of the first constraint portion 210 and the second constraint portion 310.
[0054] On the moving structure of the first clamping member 200 and the second clamping member 300, the first clamping member 200 is provided with a first guide member, and the second clamping member 300 is provided with a second guide member. The first guide member and the second guide member are matched and connected, and are at least used for guiding the second clamping member 300 to move in the second direction. Specifically, the first clamping member 200 includes a plurality of guide posts 240, and the guide posts 240 extend along the second direction. The plurality of guide posts 240 are evenly arranged on the first clamping member 200, and the second clamping member 300 includes a plurality of guide holes 340, and the guide holes 340 penetrate the third surface 320 and the fourth surface 330. The plurality of guide holes 340 are evenly arranged on the second clamping member 300 accordingly.
[0055] In this embodiment, a guide column 240 is provided on the first clamping member 200, wherein the wire column can extend from the second surface 230 toward the second direction, and a guide hole 340 extending along the second direction is correspondingly provided on the second clamping member 300, and the guide hole 340 penetrates the second clamping member 300 in the second direction. During installation, the third surface 320 of the second clamping member 300 is aligned with the first surface 220 of the first clamping member 200, and then the guide column 240 is inserted into the guide hole 340 at the corresponding position. When the second clamping member 300 is moved along the second direction, the guide column 240 and the guide hole 340 cooperate with the guide limit, thereby improving the accuracy of the movement of the second clamping member 300, and effectively ensuring the alignment accuracy of the first constraint portion 210 and the second constraint portion 310, thereby improving the uniformity of dispensing.
[0056] In addition, the fixture also includes an elastic locking member 600, which includes a connected locking block 610 and an elastic member 620. A placement groove 241 is provided on the surface of the guide column 240, and the elastic member 620 is fixedly connected in the placement groove 241. The locking block 610 is movably arranged in the placement groove 241 and is movably configured with a first state and a second state. In the first state, the locking block 610 is completely accommodated in the placement groove 241, and the elastic member 620 is in an elastic compression state so that the guide hole 340 and the guide column 240 can be moved and matched. In the second state, the locking block 610 partially protrudes from the surface of the guide column 240, and the elastic member 620 is in an elastic extension state to limit the movement and matching of the guide hole 340 and the guide column 240.
[0057] In another embodiment, if Figure 6 , 7As shown, an elastic locking member is also provided on the guide column 240, and the elastic locking member includes a locking block 610 and an elastic member 620, wherein a placement groove 241 extending along its own radial direction is provided on the surface of the guide column 240, one end of the elastic member 620 is fixedly connected to the bottom of the placement groove 241, and the other end of the elastic member 620 is fixedly connected to the locking block 610, and the locking block 610 can move radially along the guide column 240 in the placement groove 241. When in use, when the second clamping member 300 and the first clamping member 200 need to be flexibly matched, the locking block 610 is driven by external force to move inside the guide column 240, and the elastic member 620 is compressed until the locking block 610 moves to the first state, at which time the locking block 610 is completely accommodated in the placement groove 241, and the guide hole 340 and the guide column 240 can achieve flexibly guided matching, and the second clamping member 300 can be arbitrarily moved on the guide column 240. When dispensing is required, after the second clamping member 300 moves to the corresponding position, that is, after the second surface 230 and the third surface 320 are in contact, the external force is removed, and the elastic member 620 elastically stretches, driving the locking block 610 to move outward, so that the locking block 610 partially protrudes from the guide column 240, thereby abutting against the fourth surface 330, so as to limit the movement of the second clamping member 300 in the second direction, and ensure the stability of the dispensing work. The elastic member 620 can be a spring.

[0059] In this embodiment, a first connecting member is provided on the first clamping member 200, and a second connecting member is provided on the second clamping member 300, wherein the first connecting member and the second connecting member can be connected magnetically. Specifically, a mounting groove can be provided on the second surface 230, and the first magnetic member 231 is placed in the mounting groove, and the depth of the mounting groove is not less than the thickness of the first magnetic member 231. Correspondingly, a mounting groove is also provided on the third surface 320, and the second magnetic member 321 is placed in the mounting groove, and the depth of the mounting groove is not less than the thickness of the second magnetic member 321. When the second surface 230 and the third surface 320 are attached to each other, the first magnetic member 231 and the second magnetic member 321 are magnetically connected to each other, wherein the first magnetic member 231 is a high-strength magnet, and the second magnetic member 321 can be a metal block or a high-strength magnet. When the second magnetic member 321 is a high-strength magnet, the magnetism of the first magnetic member 231 and the second magnetic member 321 are opposite. Alternatively, the second magnetic member 321 may be a high-strength magnet, and the first magnetic member 231 may be a metal block or a high-strength magnet. When the first magnetic member 231 is a high-strength magnet, the magnetism of the first magnetic member 231 and the second magnetic member 321 are opposite.
