Description

Technical Field

[0001] The present invention relates to the technical field of automated equipment, and specifically to an automatic pin inserter. Background Art

[0002] A pin inserter is an automated device that inserts pins into designated positions. Currently, there is a need for pin insertion in many fields, such as electronic component assembly, connector assembly, and so on.

[0003] In actual use, pin insertion is mostly carried out manually, with low pin insertion efficiency, poor accuracy, and a high defect rate. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic pin inserter to solve the above problems and achieve automated pin insertion.

[0005] The present invention achieves the above purpose through the following technical solutions. An automatic pin inserter includes:

[0006] A striking pin;

[0007] A striking pin buffer mechanism, where the striking pin buffer mechanism includes a fixing block fixedly connected to the striking pin, a first elastic element fixedly connected to the fixing block, and a driving element fixedly connected to the first elastic element. The extending direction of the first elastic element is the same as that of the striking pin;

[0008] A feeding member, which has a feeding channel and a striking pin channel for the striking pin to embed and move. The feeding channel communicates with the striking pin channel. The feeding member has a feeding port for the pins to enter, and the feeding member is also provided with an outlet for the striking pin and the pins entering from the feeding channel to pass through;

[0009] An opening and closing jaw, which has two clamping parts that can open and close; when the two clamping parts are in the closed state, a pin insertion channel is formed. The pin insertion channel has a pin insertion inlet and a pin insertion outlet, and both the pin insertion inlet and the pin insertion outlet communicate with the pin insertion channel respectively. The pin insertion inlet faces the outlet; along the direction from the pin insertion inlet to the pin insertion outlet, the inner diameter of the pin insertion channel gradually becomes smaller; when the two clamping parts are in the closed state, the tip of the pin entering from the outlet into the inlet can pass through the pin insertion channel and extend out of the pin insertion outlet, and the tail of the pin entering from the outlet into the inlet can enter the pin insertion channel and cannot extend out of the pin insertion outlet; when the two clamping parts are in the open state, the pins in the pin insertion channel can freely fall;

[0010] The firing pin can extend out of the outlet and enter the pin insertion channel, and at the same time can squeeze the two clamping parts so that the two clamping parts are in an open state; the firing pin can also disengage from the pin insertion channel, so that the two clamping parts are in a closed state; the firing pin moving towards the needle can apply the power for inserting the needle to the needle.

[0011] Further, the opening and closing type clamping jaw further includes two connecting shafts, and the two clamping parts respectively correspond to the two connecting shafts one by one. The clamping part is rotationally connected to the corresponding connecting shaft, and a second elastic element is connected between the two clamping parts.

[0012] Further, the fixed block is a round block sleeved on the outer wall of the firing pin, the elastic element is sleeved around the firing pin, the driving element is connected with a connecting block, and the two ends of the elastic element are respectively connected to the connecting block and the round block.

[0013] Further, the automatic pin inserting machine further includes a pin insertion abnormality detection sensor, and the pin insertion abnormality detection sensor is arranged on the connecting block. When the needle falling out of the pin insertion outlet cannot be accurately inserted into the pin insertion position of the pin tray, the needle is collided, and the needle will apply a force to the firing pin. Due to the existence of the firing pin buffer mechanism, the firing pin buffer mechanism will move upward relative to the pin insertion abnormality detection sensor and be detected by the pin insertion abnormality detection sensor.

[0014] Further, the automatic pin inserting machine further includes a mounting bracket, the driving element is mounted on the inner wall of the mounting bracket, and the feeding part is mounted at the bottom of the mounting bracket.

[0015] Further, the automatic pin inserting machine further includes a robot for driving the mounting bracket to move. The robot is connected with a moving platform, and the moving platform is detachably and fixedly connected with the mounting bracket.

[0016] Further, the robot includes 3 groups of link groups, each group of link groups includes 2 links, one end of the link is rotationally connected to the moving platform, and the other end of the link is connected with a linear motion module capable of moving longitudinally.

[0017] Further, the first elastic element is a spring.

[0018] Further, the second elastic element is a spring.

[0019] Further, the driving element is a cylinder.

[0020] The beneficial effects of the present invention are as follows: An automatic pin inserting machine provided by this application first inputs pins from the feed inlet of the feeding member into the feed channel, and then the pins come out from the outlet and fall into the pin inserting channel. At this time, the two clamping parts of the opening and closing type clamping jaws are in a closed state. Since the inner diameter of the pin inserting channel gradually decreases along the direction from the pin inserting inlet to the pin inserting outlet, the needle tips of the pins entering the inlet from the outlet can pass through the pin inserting channel and extend out of the pin inserting outlet, while the needle tails of the pins entering the inlet from the outlet can enter the pin inserting channel and cannot extend out of the pin inserting outlet. Therefore, at this time, the needle tails are stuck in the pin inserting channel, and the pins cannot fall freely and cannot be inserted into the designated positions on the pin tray. Then the driving element works. The driving element drives the fixed block to move through the first elastic element, and further drives the impact pin to move. The impact pin gradually inserts into the pin inserting channel, gradually squeezes the two clamping parts and pushes the two clamping parts apart, so that the two clamping parts are in an open state. At this time, the pins originally stuck in the pin inserting channel can fall freely and be inserted into the designated positions on the pin tray; realizing automatic pin insertion, with high pin insertion efficiency and low defect rate.

[0067] Refer to Figures 1-9 As shown, a preferred embodiment is provided for the present invention.

[0068] An automatic pin inserting machine, comprising:

[0069] A striker 10;

[0070] A striker buffer mechanism 20, the striker buffer mechanism 20 includes a fixed block 21 fixedly connected to the striker 10, a first elastic element 22 fixedly connected to the fixed block 21, and a driving element 23 fixedly connected to the first elastic element 22, and the extending direction of the first elastic element 22 is the same as the extending direction of the striker 10;

[0071] A feeding member 30, the feeding member 30 has a feeding channel 31 and a striker channel 32 for the striker 10 to embed and move, the feeding channel 31 communicates with the striker channel 32, the feeding member 30 has a feeding port 33 for the needle to enter, and the feeding member 30 is further provided with an outlet 34, and the outlet 34 is used for the striker 10 and the needle entering from the feeding channel 31 to pass through;

[0072] An opening and closing jaw 40, the opening and closing jaw 40 has two clamping parts that can open and close; the two clamping parts form a pin inserting channel 42 when in the closed state, the pin inserting channel 42 has a pin inserting inlet 421 and a pin inserting outlet 42234, the pin inserting inlet 421 and the pin inserting outlet 42234 both communicate with the pin inserting channel 42 respectively, and the pin inserting inlet 421 faces the outlet 34; along the direction from the pin inserting inlet 421 to the pin inserting outlet 42234, the inner diameter of the pin inserting channel 42 gradually becomes smaller; when the two clamping parts are in the closed state, the needle tip of the pin entering from the outlet 34 can pass through the pin inserting channel 42 and extend out of the pin inserting outlet 42234, and the needle tail of the pin entering from the outlet 34 can enter the pin inserting channel 42 and cannot extend out of the pin inserting outlet 42234; when the two clamping parts are in the open state, the needle in the pin inserting channel 42 can freely fall;

[0073] The striker 10 can extend out of the outlet 34 and enter the pin inserting channel 42, and at the same time can squeeze the two clamping parts to make the two clamping parts in the open state; the striker 10 can also disengage from the pin inserting channel 42, so that the two clamping parts are in the closed state; the striker moving towards the needle can apply the power of inserting the pin to the needle.

[0074] An automatic pin insertion machine provided above first inputs the pins from the feed inlet 33 of the feed member 30 into the feed channel 31, and then the pins come out from the outlet 34 and fall into the pin insertion channel 4242. At this time, the two clamping parts of the opening and closing jaw 40 are in a closed state. Since the inner diameter of the pin insertion channel 4242 gradually decreases along the direction from the pin insertion inlet 421 to the pin insertion outlet 42234, the needle tips of the pins entering the inlet from the outlet 34 can pass through the pin insertion channel 4242 and extend out of the pin insertion outlet 42234, and the needle tails of the pins entering the inlet from the outlet 34 can enter the pin insertion channel 4242 and cannot extend out of the pin insertion outlet 42234. Therefore, the needle tails are stuck in the pin insertion channel 4242 at this time, and the pins cannot freely fall and cannot be inserted into the designated positions on the pin tray. Then the driving element 23 works. The driving element 23 drives the fixed block 21 to move through the first elastic element 22, and then drives the striker 10 to move. The striker 10 gradually inserts into the pin insertion channel 4242. The striker 10 gradually presses the two clamping parts and squeezes open the two clamping parts, so that the two clamping parts are in an open state. At this time, the pins originally stuck in the pin insertion channel 4242 can freely fall and be inserted into the designated positions on the pin tray; realizing automatic pin insertion, with high pin insertion efficiency and low defect rate.

[0075] As an embodiment of the present application, the opening and closing jaw 40 further includes two connecting shafts 43. The two clamping parts respectively correspond to the two connecting shafts 43 one by one. The clamping part is rotationally connected to the corresponding connecting shaft 43, and a second elastic element 44 is connected between the two clamping parts; due to the existence of the second elastic element 44, without applying an external force to the two clamping parts, the two clamping parts are clamped, so that the two clamping parts are in a closed state; at the same time, since the two clamping parts on both sides can rotate and due to the existence of the elastic element, when the striker 10 presses the two clamping parts, the pressing force formed by the striker 10 pressing the clamping parts causes the two clamping parts to move away from each other, so that the two clamping parts are in an open state.

[0076] Preferably, the clamping part and the corresponding connecting shaft 43 are rotationally connected through a tapered bearing, so that the rotation of the clamping part is more stable and not easily deformed.

[0077] As an embodiment of the present application, the fixed block 21 is a round block sleeved on the outer wall of the striker 10. The elastic element is sleeved around the striker 10. The driving element 23 is connected with a connecting block 24. The two ends of the elastic element are respectively connected to the connecting block 24 and the round block; in this way, through this setting method, the elastic force direction of the elastic element is the same as the movement direction of the striker 10, so that the striker 10 has a buffer in its movement direction.

[0078] As an implementation manner of the present application, the automatic pin inserter further includes a pin insertion abnormality detection sensor 50, and the pin insertion abnormality detection sensor 50 is disposed on the connection block 24. When the pins falling out from the pin outlet 42234 cannot be accurately inserted into the pin insertion positions of the pin tray, the pins are collided, and the pins will apply a force to the striker 10. Due to the presence of the striker buffer mechanism 20, the striker buffer mechanism 20 will move upward relative to the pin insertion abnormality detection sensor 50 and be detected by the pin insertion abnormality detection sensor 50; by arranging the pin insertion abnormality detection sensor 50 and the striker buffer mechanism 20 ingeniously, when a pin insertion abnormality occurs, the pin insertion abnormality detection sensor 50 can detect the pin insertion abnormality, and timely feedback to the alarm device of the pin inserter and make it emit an alarm. At the same time, the automatic pin inserter will move to a specified position to perform a pin discharging operation on the pins with abnormal insertion.
