[0016] To achieve the above-mentioned purpose, the method for using the fixture of the present invention comprises the following steps:

[0017] 1) The step of taking out the molded part from the molding die, the step comprising: 1.1) the manipulator drives the fixture to move horizontally to the material taking station in the direction close to the molding die, and before the manipulator drives the fixture to move horizontally to the material taking station, the swing driver drives the positioning baffle to pivot to the avoidance position and the lateral clamping mechanism is in an open state; 1.2) the grabbing and breaking mechanism takes out the molded part from the molding die and places the molded part in the workpiece placement area;

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0029] See also Figure 1 and Figure 2 The jig 100 of the present invention is used in conjunction with a robot (not shown in the figure), and the robot drives the jig 100 of the present invention to move back and forth between the molding die and the classification collection location; after the jig 100 of the present invention takes out the molded part 200 from the molding die, the jig 100 of the present invention uses the robot to drive the jig 100 of the present invention to move horizontally to the classification collection location (such as the finished product frame and the sprue frame described below) to achieve the purpose of secondary positioning of the molded part 200 after taking out, breaking the sprue 210 in the molded part 200, and separating and classifying the sprue 210 and the finished product 220.

[0030] Among them, combined Figure 3 , Figure 4 and Figure 6 The fixture 100 of the present invention includes a fixture base 10, a positioning baffle 20 pivotally connected to the fixture base 10 by means of a pivot shaft 31, and a positioning baffle 20 installed on the fixture base 10 and driving the positioning baffle 20 to Figure 4 The positioning position and Figure 1 The swing drive 30 for switching between the avoidance positions shown, the grabbing and breaking mechanism 40 installed on the fixture base 10, and the lateral clamping mechanism 50 installed on the fixture base 10. The lateral clamping mechanism 50 has a Figure 3 The workpiece placement area 70 shown in FIG. 1 is used for taking out the molded part 200 in the molding die and placing the molded part 200 in the workpiece placement area 70. Figure 3 The positioning baffle 20 is driven by the swing drive 30 to pivot to the bottom of the lateral clamping mechanism 50 and is in the position shown in FIG. Figure 4The positioning position shown in the figure enables the positioning baffle 20 in the positioning position to support and position the finished product 220 in the molded part 200 in the workpiece placement area 70 from the bottom; the lateral clamping mechanism 50 clamps and positions the finished product 220 supported and positioned by the positioning baffle 20 from the side, and the grabbing and breaking mechanism 40 breaks the water outlet 210 in the molded part 200 to separate the water outlet 210 from the finished product 220. After the water outlet 210 is separated from the finished product 220, and in the process of the manipulator driving the jig 100 of the present invention to move horizontally to the finished product frame, the grabbing and breaking mechanism 40 first clamps the water outlet 210, and at the same time, the swing driver 30 drives the positioning baffle 20 to pivot to the avoidance position and the lateral clamping mechanism 50 is in the open state, so that the finished product 220 automatically falls into the finished product frame when it loses the positioning effect of the lateral clamping mechanism 50 and the positioning baffle 20, and the falling state of the finished product 220 is shown. Figure 6 As shown; the grabbing and breaking mechanism 40 releases the clamping of the nozzle 210 when the manipulator drives the fixture 100 of the present invention to move horizontally to the nozzle frame, so that the nozzle 210 automatically falls into the nozzle frame. More specifically, as follows:

[0031] like Figure 1 to Figure 2As shown, the grabbing and breaking mechanism 40, the lateral clamping mechanism 50 and the swing driver 30 are each located directly below the fixture base 10, so as to avoid the grabbing and breaking mechanism 40, the lateral clamping mechanism 50 and the swing driver 30 from causing obstacles to the top of the fixture base 10, thereby ensuring the flatness and reliability of the top of the fixture base 10 and the manipulator being fixed together, and also avoiding the grabbing and breaking mechanism 40, the lateral clamping mechanism 50 and the swing driver 30 from interfering with the manipulator, thereby ensuring the reliability of the grabbing and breaking mechanism 40, the lateral clamping mechanism 50 and the swing driver 30. At the same time, the lateral clamping mechanism 50, the grabbing and breaking mechanism 40 and the swing driver 30 are sequentially displaced along the axial direction of the pivot shaft 31 (i.e., the direction indicated by arrow A and the opposite direction) to ensure the compactness and rationality of their installation and fixation on the fixture base 10. Specifically, there are two lateral clamping mechanisms 50 which are spaced apart from each other along the axial direction of the pivot shaft 31, and the grabbing and breaking mechanism 40 and the swing driver 30 are located between the lateral clamping mechanisms 50. Such a design can increase the clamping and positioning strength of the lateral clamping mechanism 50 on the finished product 220 in the molded part 200, but is not limited thereto. At the same time, the output end of the swing driver 30 forms the pivot shaft 31, and the positioning baffle 20 is installed at the output end of the swing driver 30. When the positioning baffle 20 is switched to the avoidance position, it is located beside the lateral clamping mechanism 50 to avoid the positioning baffle 20 causing obstacles to the material taking work of the grabbing and breaking mechanism 40 when positioning is not required. More specifically, in order to further avoid interference with the material picking of the molded part 200, as well as interference with the lateral clamping mechanism 50 and the grasping and breaking mechanism 40, the fixture 100 of the present invention also includes a swing arm 60, the first end of the swing arm 60 is installed at the output end of the swing drive 30, and the second end of the swing arm 60 extends to the positioning baffle 20 and is fixedly connected to the positioning baffle 20. Preferably, the second end of the swing arm 60 is fixedly connected to the positioning baffle 20 in the middle of the side in the length direction to ensure the supporting strength of the swing arm 60 on the positioning baffle 20, but it is not limited to this.

[0032] like Figure 1 to Figure 2As shown, the lateral clamping mechanism 50 comprises a first clamping plate 51 and a second clamping plate 52 which are loosely clamped and matched with each other, and a pneumatic clamping finger 53 used to drive the first clamping plate 51 and the second clamping plate 52 to loosely clamp. The pneumatic clamping finger 53 is installed on the fixture base 10 with the clamping jaw 531 facing downward, and the fixture base 10 provides support and fixing for the pneumatic clamping finger 53. The first clamping plate 51 is installed on one clamping jaw 531 of the pneumatic clamping finger 53, and the second clamping plate 52 is installed on the other clamping jaw 531 of the pneumatic clamping finger 53; therefore, under the drive of the pneumatic clamping finger 53, the first clamping plate 51 and the second clamping plate 52 are loosely clamped to achieve lateral (for example, left and right sides of the finished product 220) clamping and positioning of the finished product 220 in the molded part 200 in the workpiece placement area 70, or to release the clamping and positioning of the finished product 220 in the molded part 200 in the workpiece placement area 70. For example, the pneumatic clamping fingers 53 of the lateral clamping mechanism 50 are Y-shaped clamping fingers, so that the first clamping plate 51 and the second clamping plate 52 both rotate during the loosening and clamping process, so that the lateral clamping mechanism 50 occupies less space on the fixture base 10, thereby further reducing the space occupied by the fixture 100 of the present invention; of course, according to actual needs, the pneumatic clamping fingers 53 of the lateral clamping mechanism 50 can also be selected as flat clamping fingers, so it is not limited to this.

[0033] like Figure 1 to Figure 2As shown, the grabbing and breaking mechanism 40 includes a clamping assembly 41 and a reciprocating drive 42 for driving the clamping assembly 41 to perform reciprocating motion. The clamping assembly 41 is installed at the output end 421 of the reciprocating drive 42 to reduce the weight of the grabbing and breaking mechanism 40. Specifically, the grabbing and breaking mechanism 40 also includes a slide 43 located directly below the fixture base 10, and the fixture base 10 extends an upper and lower suspension 11 toward the slide 43. The slide 43 is slidably arranged on the upper and lower suspensions 11, and the upper and lower suspensions 11 provide support for the slide 43; the sliding direction of the slide 43 (i.e., the direction indicated by arrow B and the opposite direction) intersects with the axial direction of the pivot shaft 31 (i.e., the direction indicated by arrow A and the opposite direction). The reciprocating drive 42 is installed at the bottom of the fixture base 10 and is located beside the upper and lower suspensions 11. The clamping assembly 41 is located directly below the slide 43. The clamping assembly 41 includes a pneumatic clamping finger 411 fixed to the slide 43 and a clamping block 412 respectively installed on the clamping claw 411a of the pneumatic clamping finger 411. Such a design is more conducive to the lightweight of the grabbing and breaking mechanism 40 and the adjustment of the clamping position of the water nozzle 210. More specifically, the reciprocating drive 42 is installed at the bottom of the fixture seat 10 in an adjustable position to flexibly adjust the clamping position of the water nozzle 210 according to actual needs to meet the requirements of different products, such as for the processing and development of bakelite terminals or bakelite plugs of different sizes. For example, the reciprocating drive 42 is a cylinder, and of course, it can be selected as a hydraulic cylinder according to actual needs; at the same time, the pneumatic clamping finger 411 of the grabbing and breaking mechanism 40 is a flat clamping finger to reduce the space occupied in the height direction. Of course, according to actual needs, the pneumatic clamping finger 411 of the grabbing and breaking mechanism 40 can also be a Y-shaped clamping finger, so it is not limited to this.

[0034] Please refer to Figures 3 to 6 The method for using the fixture 100 of the present invention comprises the following steps:

[0035] 1) The step of taking out the molded part 200 from the molding mold comprises: 1.1) the manipulator drives the fixture 100 to move horizontally to the material taking station in the direction close to the molding mold, and before the manipulator drives the fixture 100 to move horizontally to the material taking station, the swing driver 30 drives the positioning baffle 20 to pivot to the avoidance position and the lateral clamping mechanism 50 is in the open state. At this time, the states of the positioning baffle 20 and the lateral clamping mechanism 50 are shown in FIG. Figure 3 1.2) The grabbing and breaking mechanism 40 takes out the molded part 200 from the molding die and places the molded part 200 in the workpiece placement area 70, and the state is shown in FIG. Figure 3 shown.

[0036] 2) The step of repositioning the molded part 200 includes: 2.1) The manipulator drives the fixture 100 to move laterally in a direction away from the molding die, and in the process of the manipulator driving the fixture 100 to move laterally, the swing driver 30 drives the positioning baffle 20 to pivot to the bottom of the lateral clamping mechanism 50 and to be in the positioning position. The state of the positioning baffle 20 at this time is shown in FIG. Figure 4 2.2) The grabbing and breaking mechanism 40 releases the molded part 200, so that the molded part 200 automatically falls to the positioning baffle 20 under the action of its own weight, and the positioning baffle 20 supports and positions the finished product 220 in the molded part 200 from the bottom; 2.3) The lateral clamping mechanism 50 clamps and positions the finished product 220 supported and positioned by the positioning baffle 20 from the side, and at the same time, the grabbing and breaking mechanism 40 also clamps the nozzle 210 in the molded part 200, and the state is shown in FIG. Figure 4 shown.

[0037] 3) The step of breaking the nozzle 210 includes: 3.1) grabbing and breaking the mechanism 40 to release the nozzle 210 and push the nozzle 210 to bend back and forth, so that the nozzle 210 is broken and separated from the finished product 220; 3.2) grabbing and breaking the mechanism 40 and then clamping the nozzle 210 separated from the finished product 220; specifically, the pneumatic clamping finger 411 drives the clamping block 412 to release the clamping of the nozzle 210, so that the nozzle 210 is located in the space 413 surrounded by the clamping block 412, and the state is shown in FIG. Figure 5 As shown, then, when the reciprocating driver 42 drives the slide 43 together with the pneumatic clamping finger 411 and the clamping block 412 to reciprocate, the nozzle 210 is offset to a certain extent, so that the nozzle 210 and the finished product 220 form an angle greater than 45 degrees, so that the connection of the nozzle 210 is automatically broken by the torsion generated by the back and forth pushing of the clamping block 412. And

[0038] 4) Classification step. In the classification step, the grabbing and breaking mechanism 40 releases the water outlet 210, and the swing driver 30 drives the positioning baffle 20 to pivot to the avoidance position and the lateral clamping mechanism 50 to be in an open state, so that the separated water outlet 210 and the finished product 220 fall to different collection places when the robot drives the fixture 100 to move horizontally; for example, when the robot drives the fixture 100 to move horizontally to the finished product frame, the swing driver 30 drives the positioning baffle 20 to pivot to the avoidance position and the lateral clamping mechanism 50 to be in an open state, so that the finished product 220 separated from the water outlet 210 loses the effects of both the positioning baffle 20 and the lateral clamping mechanism 50 and automatically falls into the finished product frame; when the robot drives the fixture 100 to move horizontally to the water outlet frame, the grabbing and breaking mechanism 40 releases the clamping of the water outlet 210, so that the water outlet 210 loses the clamping of the clamping component 41 of the grabbing and breaking mechanism 40 and automatically falls into the water outlet frame.

[0039] Compared with the prior art, the jig 100 of the present invention includes a jig base 10, a positioning baffle 20 pivotally connected to the jig base 10 by means of a pivot shaft 31, a swing driver 30 installed on the jig base 10 and driving the positioning baffle 20 to switch between a positioning position and an avoidance position, a grabbing and breaking mechanism 40 installed on the jig base 10, and a lateral clamping mechanism 50 installed on the jig base 10. The lateral clamping mechanism 50 has a workpiece placement area 70 when in an open state. The grabbing and breaking mechanism 40 is used to take out the molded part 200 in the molding mold and place the molded part 200 in the workpiece placement area 70. The positioning baffle 20 is pivotally swung to the bottom of the lateral clamping mechanism 50 under the drive of the swing driver 30. The finished product 220 in the molded part 200 in the workpiece placement area 70 is supported and positioned from the bottom, and the lateral clamping mechanism 50 clamps and positions the finished product 220 supported and positioned by the positioning baffle 20 from the side, and the grabbing and breaking mechanism 40 breaks the water outlet 210 in the molded part 200; therefore, with the cooperation of the swing drive 30, the positioning baffle 20, the lateral clamping mechanism 50 and the grabbing and breaking mechanism 40, the fixture 100 of the present invention can integrate the functions of material collection, positioning, breaking and separation. On the one hand, it can reduce the complexity of equipment development and reduce the overall footprint to have the advantages of precise positioning and small space volume. On the other hand, it can realize the automatic separation and classification of the water outlet 210 and the finished product 220 in one step. At the same time, since the swing drive 30 drives the positioning baffle 20 to pivot to the bottom of the lateral clamping mechanism 50 and performs secondary positioning on the finished product 220 in the molded part 200 from the bottom, the shaking caused when taking out the clamping water outlet 210 is reduced. This can be achieved without the use of additional positioning table tooling, reducing the design of positioning tooling and shortening the corresponding cycle.

[0040] The above disclosure is only a preferred embodiment of the present invention, which is to facilitate the understanding and implementation of the present invention by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
