[0029] The embodiment of the present specification discloses a mold pressing automatic crimping device, which is described in detail below.

[0030] Figure 1 A structure diagram of a mold pressing automatic crimping device provided by an embodiment of the present specification is shown in the figure. Figure 1 As shown in the figure, a mold pressing automatic crimping device includes an automatic crimping pliers 1, a pressing mold 2, and a positioning tool 3. Among them, the automatic crimping pliers 1 can be powered by a lithium battery to realize automatic crimping; the pressing mold 2 is designed according to the shape of the 6# jack, the pin and the wire, and the outer shape of the pressing mold 2 is matched with the automatic crimping pliers, and the pressing mold 2 is installed on the automatic crimping pliers 1 for product crimping; the positioning tool 3 is used to fix the 6# jack and the pin, and the positioning tool 3 is provided with a height adjusting structure, which is used to fix the position of the 6# jack and the pin relative to the automatic crimping pliers 1.

[0031] In the technical scheme of the present application, the automatic crimping pliers is powered by a lithium battery, which can realize automatic crimping and abandon manual operation. At the same time, since the pressing mold is designed according to the shape of the 6# jack, the pin and the wire, and its outer shape is matched with the automatic crimping pliers, so that the pressing film can be accurately attached to the crimped parts, ensuring that the stress of each part is uniform during crimping, and improving the crimping quality and consistency. The positioning tool fixes the 6# jack and the pin by adjusting the clamping height, so that the position of the 6# jack and the pin is fixed relative to the automatic crimping pliers, and the operator does not need to hold the crimping pliers and manually clamp the wire, so that one hand can insert the wire and the other hand can operate the crimping pliers, which is more convenient to operate, improves the accuracy and stability of positioning, and further ensures the crimping quality.

[0032] Based on the foregoing technical scheme, some more specific structures are also provided, which are described below.

[0033] In the optional embodiment technical scheme, as shown in the figure, Figure 2 Figure 2 ​The structure diagram of a die of a die automatic pressure connection device is provided for an embodiment of the present specification. The die 2 can be composed of two half-circular structures. The shape of the half-die is a three-layer circular boss structure, including an uppermost layer boss, an intermediate layer boss, and a lowermost layer boss. The three-layer boss structure is integrally formed. A recess is arranged at the center of the bottom surface of the lowermost layer boss. The shape of the recess is half of a regular hexagon, and the size is suitable for a 6# jack, a pin, and the like. The two half-circular dies are combined to form the required shape during pressure connection. Specifically, the diameter of the uppermost layer boss can be 8 mm, the diameter of the intermediate layer boss can be 14 mm, and the diameter of the lowermost layer boss can be 35 mm.

[0034] In the technical solution of the present embodiment, the die composed of two half-circles has low manufacturing and processing difficulty, is convenient to install and maintain, and can be replaced with a single half-circle die when wear or damage occurs. During pressure connection, the two half-circular dies can be combined from both sides to ensure uniform and stable pressure connection and avoid loose connection or quality problems.

[0035] In addition, the three-layer circular boss structure of the half-die is integrally formed, has high structural strength, and is stable. The bosses with different diameters in the upper layer, the intermediate layer, and the lowermost layer accurately position and fix different parts of the 6# jack, the pin, and the wire, respectively. The lowermost layer boss can also stably connect the automatic pressure connection pliers. The recess at the center of the bottom surface of the lowermost layer boss is half of a regular hexagon, which is consistent with the shape of the 6# jack and the pin, and has a suitable size. The recess can accurately position and uniformly distribute pressure to prevent pressure connection defects.

[0036] In the technical solution of the present embodiment, during pressure connection, the two half-circular dies move towards each other by the driving of the automatic pressure connection pliers and gradually combine. During the combining process, the three-layer circular boss structure and the recess at the bottom work cooperatively. First, the uppermost layer boss preliminarily positions and guides the top of the 6# jack and the pin and the insertion end of the wire, so that they can accurately enter the working area of the die. Then, the intermediate layer boss further fixes and clamps the middle part of the 6# jack and the pin to enhance the positioning effect. Finally, the recess of the lowermost layer boss accurately embeds the 6# jack and the pin therein to achieve accurate positioning and stable support. With the gradual combination of the two half-circular dies, they apply uniform pressure to the 6# jack, the pin, and the wire to complete the pressure connection operation, so that the wire is tightly connected with the jack and the pin, and the required pressure connection shape and quality requirements are achieved.

[0037] In the optional technical solution of the present embodiment, a chamfer is arranged at the upper edge of the intermediate layer boss, and a chamfer is arranged at the lower edge of the lowermost layer boss.

[0038] In the technical solution of the present embodiment, the chamfer at the upper edge of the intermediate layer boss can guide the wire or related components to smoothly enter the working area of the die, so as to avoid scratching the insulating layer of the wire or damaging the 6# jack and the pin due to the sharp edge.

[0039] In an alternative embodiment, as shown in Figure 1 The positioning tool can include a vertical rod 31 and a positioning clamp 32, the vertical rod 31 is vertically fixed, the positioning clamp 32 is arranged on the vertical rod 31 and moves up and down along the vertical rod 31, and the positioning clamp 32 is used to fix the 6# jack and the pin.

[0040] In the embodiment, the vertical rod 31 can be made of high-strength metal material such as aluminum alloy or stainless steel to ensure that it will not be easily deformed by external force during use. The shape of the vertical rod 31 is generally cylindrical, and the diameter is determined according to the overall size and load bearing requirement of the positioning tool. The vertical rod 31 can be installed on the base 4 in a vertically fixed manner.

[0041] The positioning clamp 32 can be composed of two oppositely arranged clamping pieces, and the inner side of the clamping pieces is designed with corresponding grooves or protrusions according to the outer shape of the 6# jack and the pin to realize close fitting and stable clamping. The outer side of the positioning clamp is provided with a connecting structure matched with the vertical rod, such as a through hole with a diameter matched with the vertical rod. Through the through hole, the positioning clamp can be sleeved on the vertical rod and move up and down along the vertical rod. In order to facilitate operation, an operating handle can be designed on the positioning clamp, and the operator can adjust the position of the positioning clamp on the vertical rod by rotating the handle to realize accurate adjustment of the height of the 6# jack and the pin.

[0042] Meanwhile, a scale mark can be provided on the vertical rod 31, and the scale can be accurate to millimeter. The operator can adjust the positioning clamp to the appropriate height according to the actual needs by referring to the scale mark. In order to ensure that the positioning clamp can be stably fixed on the vertical rod after adjustment, a clamping bolt can be installed on the side of the positioning clamp. When the positioning clamp is moved to the appropriate position, the clamping bolt is tightened to make the inner wall of the through hole of the positioning clamp tightly hold the vertical rod, so as to realize the fixation of the positioning clamp.

[0043] Therefore, in the embodiment, the operator can first adjust the height of the positioning clamp on the vertical rod according to the size of the 6# jack and the pin and the crimping requirement by operating the handle or the knob, and accurately adjust the positioning clamp to the appropriate position by referring to the scale mark on the vertical rod, and then fix the positioning clamp by using the positioning locking device. Then, the 6# jack and the pin are placed between the clamping pieces of the positioning clamp, and the elastic clamping force of the clamping pieces is used to firmly fix them, and then the specific crimping operation can be carried out.

[0044] In an alternative embodiment, the base of the positioning tool is provided with a rubber suction cup, and the rubber suction cup is used to adsorb the positioning tool on the workbench.

[0045] Considering that the automatic crimping pliers will generate vibration and impact force in the automatic crimping process, if the positioning tool is unstable, the 6# jack and pin will displace. To solve this technical problem, in the embodiment, the rubber suction cup can be pasted on the bottom of the base of the positioning tool by strong glue, so as to keep the positioning tool stable and ensure that the jack and pin are always in the accurate position during crimping. For example, in high-frequency and high-intensity crimping operation, the rubber suction cup can be continuously and stably adsorbed, avoiding the shaking and deviation of the positioning tool, so that the whole crimping process is stable.

[0046] In the optional embodiment, the mold automatic crimping device can further include a magnet arranged on the movable part of the automatic crimping pliers and a Hall sensor fixed at a corresponding position.

[0047] In the embodiment, the magnet can be installed on the movable part of the automatic crimping pliers, such as the movement rod of the crimping execution part. In this way, during the crimping process, the magnet will also move synchronously with the reciprocating movement of the movable part. For example, the magnet can be inlaid on the surface of the movement rod and be firmly fixed by using high-strength glue to avoid loosening or falling off during the operation of the equipment.

[0048] The Hall sensor needs to be installed at a position corresponding to the magnet to ensure that the change of the magnetic field generated by the movement of the magnet can be accurately detected. Specifically, when the magnet is installed on the movable part, the Hall sensor should be installed near the movement track of the movable part, and the magnet should be able to effectively cover the sensing area of the Hall sensor during movement.

[0049] When the automatic crimping pliers perform the crimping operation, the magnet will move with the movable part or the driving motor shaft, so that the relative position between the magnet and the Hall sensor changes, resulting in the change of the magnetic field strength and direction around the Hall sensor. The Hall sensor works based on the Hall effect and can convert the change of the magnetic field into an electrical signal output when the magnetic field changes. The electrical signal can be used to accurately count the number of crimping. Each time the crimping pliers complete a crimping action, the magnet will complete a movement relative to the Hall sensor, and the Hall sensor will output a corresponding electrical signal pulse. By counting these pulse signals, the number of crimping of the crimping pliers can be accurately counted. In the production process, the production manager can count the production of products according to the number of crimping, and also can analyze the use frequency and wear of the equipment by analyzing the number of crimping, so as to timely maintain and maintain the equipment and prolong the service life of the equipment.

[0050] In an optional embodiment, the positioning tool can include a base, a clamping mechanism arranged on the base, and a height adjustment mechanism, the clamping mechanism being mounted on the base through the height adjustment mechanism, the clamping mechanism being used to clamp the 6# jack and the pin, and the height adjustment mechanism being used to adjust the height of the clamping mechanism. The height adjustment mechanism can be a lead screw nut mechanism, which includes a lead screw fixed on the base and a nut matched with the lead screw, the clamping mechanism being fixed on the nut, and the height adjustment of the clamping mechanism being realized by rotating the lead screw.

[0051] In the embodiment, the height adjustment mechanism of the positioning tool adopts a lead screw nut mechanism, which mainly includes a lead screw fixed on the base and a nut matched with the lead screw. When a rotating force is applied to the lead screw, the lead screw cannot move axially because it is fixed on the base, while the nut moves linearly along the axial direction of the lead screw due to the thread matching between the lead screw and the nut according to the working principle of the thread.

[0052] Meanwhile, the clamping mechanism is fixed on the nut, and when the nut moves linearly due to the rotation of the lead screw, the clamping mechanism moves synchronously. By controlling the rotating direction and the number of rotations of the lead screw, the moving direction and distance of the nut can be accurately controlled, and thus the height adjustment of the clamping mechanism can be realized. If it is needed to raise the clamping mechanism, the nut moves upward along the lead screw to drive the clamping mechanism to rise by rotating the lead screw in a specific direction, and vice versa.

[0053] Finally, the height of the clamping mechanism is adjusted by the lead screw nut mechanism, so that the 6# jack and the pin can be kept at the required relative position with the die of the automatic crimping pliers, and the connection between the wire, the 6# jack and the pin can be ensured to be tight and accurate during the crimping process.

[0054] In an optional embodiment, the positioning tool can further be provided with a wire guide groove, which is shaped to match the wire and is used to guide the wire to be inserted into the 6# jack or the pin.

[0055] In the embodiment, the wire guide groove is designed to overcome the positional deviation problem that may occur during the insertion of the wire into the 6# jack or the pin. Since the 6# jack and the pin are small in size and high in positional accuracy, the wire may not be accurately inserted due to improper operation during manual insertion, resulting in failure or poor quality of crimping. The wire guide groove provides an accurate guide path, which can help the operator to more easily and accurately insert the wire into the target position, reduce the number of adjustments during the insertion of the wire, and thus improve the efficiency and quality of the overall crimping work.

[0056] The shape of the wire guide groove can be specially designed according to the shape of the wire. For example, if the wire is circular in cross section, the cross section of the guide groove can be designed as a semicircle or a U shape. Among them, the radius of the semicircular guide groove is slightly larger than the radius of the wire, which can ensure smooth sliding of the wire in the groove and also play a certain restraining effect on the wire to prevent it from deviating too much during insertion. The U-shaped guide groove is suitable for some special wires, such as flat wires or multi-strand wires, and the width of the bottom can be accurately designed according to the width of the wire.

[0057] In actual crimping operation, the operator only needs to put one end of the wire into the guide groove, and then push along the direction of the guide groove, so as to accurately insert the wire into the 6# jack or pin. Thus, the deviation of the wire caused by manual operation can be greatly reduced, the good contact between the wire and the jack or pin is ensured, the crimping quality is improved, and finally the defective rate is reduced.

[0058] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the utility model. Here, all the embodiments need not and cannot be exhausted. Any modification, equivalent substitution and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
