[0002] In the prior art, when inserting the legs of a TO (Transistor-Outline) into an electrode holder, since the inner diameter of the socket of the electrode holder is relatively narrow, there may be certain errors in the positioning between the TO and the electrode holder during the actual insertion, which may cause the legs of the TO to easily collide with each other during the insertion into the electrode holder, or the friction between the legs of the TO and the inner wall of the electrode holder may damage the TO pins, causing the legs of the TO to bend or even break.

[0068] Embodiment 1:

[0069] Embodiment 1 of the present invention provides a TO tube leg flexible placement device, such as Figure 1 As shown, it includes: a fixing frame 1, a suction nozzle tube 2, a transmission wheel set 3 and a motor 4, wherein:

[0070] The suction nozzle pipe 2 is rotatably arranged on the fixing frame 1 , the motor 4 is arranged on the fixing frame 1 , and the motor 4 and the suction nozzle pipe 2 are connected and linked via the transmission wheel set 3 .

[0071] In this embodiment, the suction nozzle tube 2 is a strip-shaped cylinder, one end of the suction nozzle tube 2 is connected to the vacuum pump, which is used to pressurize or depressurize the inside of the suction nozzle tube 2, and the front end of the suction nozzle tube 2 is provided with an opening connected to the vacuum pump for adsorbing TO5; Figure 2 As shown, in the present device, the front end of the suction nozzle tube 2 faces downward, and the middle part of the suction nozzle tube 2 is sleeved with the fixing platform 13 extending from the upper end of the fixing frame 1, and the fixing platform 13 is protruded relative to the vertical projection of the fixing frame 1; it is worth mentioning that the connection between the suction nozzle tube 2 and the fixing platform 13 is a rotatable sleeve connection, that is, on the basis of the sleeve connection, the suction nozzle tube 2 can be rotated in the fixing platform 13; the part of the suction nozzle tube 2 above the fixing platform 13 can be bent to save space and connect with the vacuum pump; as shown in FIG. Figure 2 and Figure 3 As shown, it should be noted that when adsorbing TO5, the front end of the suction nozzle tube 2 is partially adsorbed with the base 51 of TO5 to ensure that the base 51 of TO5 is in contact with the front end of the suction nozzle tube 2, and the tube leg 52 of TO5 faces downward for subsequent insertion into the electrode holder 6.

[0072] In this embodiment, Figure 2As shown, the motor 4 is arranged at the upper end of the fixing frame 1, and the lower end of the motor 4 is at the same horizontal height as the lower end of the fixing platform 13 for sleeved suction nozzle pipe 2, and the transmission wheel group 3 is arranged at the lower end of the motor 4 and the lower end of the fixing platform 13, wherein the transmission wheel group 3 includes: a first transmission wheel 31, a second transmission wheel 32 and a transmission belt 33, the first transmission wheel 31 and the second transmission wheel 32 are linked by the transmission belt 33, the first transmission wheel 31 is arranged at the lower end of the fixing platform 13, and is used to be sleeved with the suction nozzle pipe 2, and the second transmission wheel 32 is connected to the fixed shaft of the motor 4; Figure 4 As shown, the motor 4 drives the first transmission wheel 31 to rotate synchronously; the first transmission wheel 31 is used to drive the suction nozzle tube 2 to rotate synchronously, thereby achieving the effect that the motor 4 drives the suction nozzle tube 2 to rotate.

[0073] like Figure 4 As shown, the lower end of the suction nozzle tube 2 is used to adsorb TO5, and the motor 4 is used to rotate in forward and reverse directions at a preset cycle, driving the suction nozzle tube 2 and TO5 to rotate in forward and reverse directions synchronously. While TO5 rotates synchronously, the fixing frame 1 drives TO5 to insert into the electrode holder 6.

[0074] Among them, the rotation in the positive and negative directions is clockwise and counterclockwise rotation, and the preset period is set by a technician in this field. The preset period is set as short as possible. The effect achieved is that TO5 makes reciprocating clockwise and counterclockwise rotations in a short time, so that it simulates the action of human hand twisting, making it easier for the TO5 tube leg 52 to be inserted into the electrode holder 6. For example, in real life, people insert nails into holes by hand. In order to buffer the friction between the nail and the inner wall of the hole, the nail is usually inserted by human hand twisting to make the insertion process easier.

[0075] Figure 4 The arrows next to the first transmission wheel 31 and the arrows next to the suction nozzle tube 2 represent the direction of rotation. It can be seen that the first transmission wheel 31 and the suction nozzle tube 2 both rotate back and forth. While rotating, the fixed frame 1 drives the tube leg 52 to be inserted into the electrode holder 6. Figure 4 The downward arrow in the middle represents the downward movement of the fixing bracket.

[0076] In the prior art, when inserting the TO5 tube leg 52 into the electrode holder 6, since the inner diameter of the socket of the electrode holder 6 is narrow and there may be a certain error in the positioning between the TO5 and the electrode holder 6, the insertion process may easily cause abutment and collision, or the friction between the TO5 tube leg 52 and the inner wall of the electrode holder 6 may cause damage to the TO5 tube leg 52, causing the TO5 tube leg 52 to bend or even break. According to actual production statistics, the scrap rate of TO5 products caused by the bending of the TO5 tube leg 52 is as high as 10%.

[0077] In this embodiment, a suction nozzle tube 2 is provided on the fixing frame 1 for sucking TO5, and a motor 4 is also provided on the fixing frame 1. The motor 4 is linked with the suction nozzle tube 2 through a transmission wheel group, and the fixing frame 1 is controlled to move TO5 to the corresponding electrode holder 6 position. In the process of inserting TO5 into the electrode holder 6, the suction nozzle tube 2 is controlled by the motor 4 to rotate back and forth, and the insertion action of TO5 is performed during the reciprocating rotation, thereby avoiding the damage or breakage of the TO5 tube leg 52 during the insertion process due to the friction between the inner wall of the electrode holder 6 and the TO5 tube leg 52.

[0078] Since the tube leg 52 of TO5 needs to be positioned and inserted into the electrode holder 6 later, TO5 needs to be accurately located at the center of the lower end of the suction nozzle tube 2. During the suction process of the suction nozzle tube 2 to suck TO5, TO5 is usually adsorbed from the feed tray, and the adsorption force cannot ensure that TO5 is accurately adsorbed at the center of the lower end of the suction nozzle tube 2. Therefore, this embodiment also involves the following designs:

[0079] like Figure 5 As shown, the fixing frame 1 is further laterally provided with a first slide rail 11 ; at least two clamps 12 are slidably provided on the first slide rail 11 .

[0080] The front end of the clamp 12 extends to the horizontal height of the lower end of the suction nozzle tube 2, and the first slide rail 11 is used for the clamp 12 to move horizontally. The at least two clamps 12 are used to move to the corresponding positions of the lower end of the suction nozzle tube 2 respectively, and the front end of the clamp 12 is used to abut against the base 51 of TO5 to align the base 51.

[0081] In this embodiment, the first slide rail 11 is horizontally arranged at the middle position of the fixing frame 1, and the clamp 12 is arranged on the first slide rail 11. The first slide rail 11 controls the clamp 12 to move on the first slide rail 11 through a cylinder. Figure 5 As shown, the fixture 12 extends out of the fixing frame 1 in the horizontal direction to reach the vertical plane where the suction nozzle tube 2 is located, and then extends vertically downward to the horizontal height where the lower end of the suction nozzle tube 2 is located, and toward the vertical position of the suction nozzle tube 2. When the two fixtures 12 move toward each other on the first slide rail 11, that is, the front ends of the two fixtures 12 move toward the lower end of the suction nozzle tube 2 and abut against the base 51 of the TO5 adsorbed at the lower end of the suction nozzle tube 2, so as to straighten the base 51 of the TO5 and position the TO5, as shown in FIG. Figure 5 As shown, the arrow in the figure is the moving direction of the clamp 12 when it abuts against the base 51; after positioning the TO5, the two clamps 12 can move in the opposite direction on the first slide rail 11 to release the abutment against the TO5 base 51 to avoid interfering with the subsequent rotation of the TO5.

[0082] The working process of the clamp 12 is as follows: after TO5 is adsorbed on the lower end of the nozzle tube 2, the two clamps 12 move toward each other synchronously on the first slide rail 11 until the front ends of the two clamps 12 abut against the TO5 base 51 to align the base 51, and then the two clamps 12 move back to back synchronously on the first slide rail 11 to release the abutment against the TO5 base 51.

[0083] It should be noted that since the outer contour of the base 51 of most TO5s is circular, in order to enable the front end of the clamp 12 to more accurately position and abut against the base 51, the front end of the clamp 12 in this embodiment is arc-shaped and matches the outer contour of the base 51.

[0084] Since some of the legs 52 of the TO5 may not be straight when the TO5 is just produced, and even different legs 52 may be connected together, which will greatly affect the process of inserting the TO5 into the electrode holder 6, before inserting the legs 52 of the TO5 into the electrode holder 6, it is necessary to separate the different legs 52 and straighten the legs 52. Therefore, this embodiment also involves the following designs:

[0085] like Figure 6 and Figure 7 As shown, Figure 7 In order to avoid hiding the fixture 12 from being blocked from view, a separation mechanism 7 is provided on the fixing frame 1, and the separation mechanism 7 comprises: a second slide rail 71, a connecting platform 72 and a separation assembly 74, wherein:

[0086] The second slide rail 71 is vertically arranged on the side of the fixing frame 1, the connecting platform 72 is slidably connected to the second slide rail 71, the separation component 74 is arranged at the lower end of the connecting platform 72, and the separation component 74 extends to the bottom of the suction nozzle tube 2; the second slide rail 71 is used to drive the separation component 74 to move in the vertical direction.

[0087] Among them, Figure 7 As shown, the second slide rails 71 are vertically arranged at the two sides of the fixing frame 1, and the two sides of the connecting platform 72 are slidably connected with the second slide rails 71 on both sides, that is, the connecting platform 72 is controlled by the cylinder to move vertically along the second slide rails 71. Figure 7 The arrow on the middle connecting platform 72 represents the direction of vertical movement. The lower end of the connecting platform 72 is a platform for setting the separation component 74. The lower end of the connecting platform 72 is slightly higher than the horizontal height of the lower end of the suction nozzle tube 2. At least two separation components 74 are set at the lower end of the connecting platform 72. The connecting platform 72 is controlled to move in the vertical direction by the second slide rail 71, thereby driving the separation components 74 at the lower end of the connecting platform 72 to move vertically synchronously. Figure 7The arrow on the separation component 74 represents the vertical movement direction of the separation component 74; when straightening the TO5 tube legs 52, it is necessary to limit the respective tube legs 52 of the TO5 through the separation component 74, and move the separation component 74 vertically while maintaining the limited state, so that each TO5 tube leg 52 can be limited by the separation component 74 from top to bottom, thereby achieving the purpose of straightening. Therefore, no matter where the separation component 74 is set at the lower end of the fixed platform 13, the separation component 74 needs to be set in the vertical direction of the suction nozzle tube 2, and the separation component 74 needs to extend to the lower end of the suction nozzle tube 2.

[0088] like Figure 8 As shown, the separation assembly 74 includes: a slide 741 and a separator 742, wherein:

[0089] The slide 741 is arranged at the lower end of the connecting platform 72, and the separator 742 is arranged on the slide 741. The separator 742 extends to the bottom of the suction nozzle tube 2, and the slide 741 and the separator 742 are both arranged toward the vertical position where the suction nozzle tube 2 is located; the slide 741 is used to drive the separator 742 to move in the horizontal direction.

[0090] In this embodiment, Figure 8 As shown, the slide 741 includes a mounting base and a slide, the slide and the mounting base are slidably connected, the slide is controlled by a cylinder to move on the mounting base, the separator 742 is arranged on the slide, and the slide is controlled by a cylinder to drive the separator 742 to move axially, the separator 742 is provided with grooves, each of the grooves is aligned with each corresponding tube leg 52 on TO5, the separator 742 moves axially toward TO5 or away from TO5, the tube leg 52 of TO5 enters the corresponding groove or exits the corresponding groove, thereby limiting the corresponding tube leg 52, Figure 8 The arrow on the separator 742 represents the moving direction of the separator 742; for all TO5s, the root of the tube leg 52 is usually the most correct in shape and position. Therefore, if the TO5 tube leg 52 is straightened by the separator 742, it is best to start straightening from a position close to the root of the tube leg 52. The root of the tube leg 52 is at the top, so when straightening, first move the front end of the separator 742 to the horizontal height of the upper end of the TO5 tube leg 52 by controlling the first slide rail 11.

[0091] Perform smoothing operations, such as Fig. 9As shown in the figure, it is the moving direction of the separator 742, and the moving sequence is in the order of the arrows A, B, C and D in the figure: A. Control the second pneumatic slide to move each separator 742 axially toward the position of TO5, and each tube leg 52 on TO5 enters into the groove of the corresponding separator 742, thereby limiting the tube leg 52 on each TO5; B. Then control the first slide rail 11 to move the separator 742 vertically downward, and each tube leg 52 on TO5 is straightened or separated under the limiting action of the groove of the separator 742; C. Then control the second pneumatic slide to move each separator 742 axially toward the position facing away from TO5, so that each tube leg 52 on TO5 withdraws from the groove of the separator 742 to avoid subsequent impact on the insertion of the tube leg 52 into the electrode holder 6; D. Finally, control the first slide rail 11 to move the separator 742 vertically upward to restore it to the initial position.

[0092] It should be noted that since the grooves on all separators 742 need to cooperate with each other, so as to limit the circumference of all the legs 52 on the TO5, according to the different distribution positions of the legs 52 on the TO5 base 51, the number of separator components 74 and the setting position of each separator component 74 need to be adjusted accordingly, as well as the size, shape and position of the grooves on the separator 742. Therefore, this embodiment also involves the following designs:

[0093] like Fig.10 and Fig.11 As shown, at least two separation components 74 are arranged on the connecting platform 72, and the at least two separation components 74 include a first separation component 74A and a second separation component 74B, and the first separation tool 742A of the first separation component 74A and the second separation tool 742B of the second separation component 74B are located at different levels.

[0094] like Fig.11 and Fig.12 As shown, a first preset number of first grooves 742A1 are provided on the front end face of the first separator 742A, a second preset number of second grooves 742B1 are provided on the front end face of the second separator 742B, and the first grooves 742A1 and the second grooves 742B1 are at a preset angle.

[0095] like Fig.12 As shown, the first groove 742A1 is used to accommodate the tube legs 52 arranged in a first direction on the TO5, and the second groove 742B1 is used to accommodate the tube legs 52 arranged in a second direction on the TO5, so as to limit the tube legs 52 on the TO5; wherein the first direction and the second direction are at the preset angle; Fig.12 The directions of the middle arrows are the first direction and the second direction.

[0096] The second slide rail 71 and the slide table 741 drive the separator 742 to reciprocate in the vertical and horizontal directions, so as to straighten the tube legs 52 on the TO5.

[0097] In this embodiment, Fig.12 As shown, two first grooves 742A1 are provided on the first separator 742A, the first grooves 742A1 are strip-shaped and parallel to each other, and two second grooves 742B1 are provided on the second separator 742B, the second grooves 742B1 are strip-shaped and parallel to each other, and the corresponding TO5 tube legs 52 are arranged in a matrix manner on the base 51.

[0098] like Fig.12 As shown, taking a TO5 with four legs 52 as an example, four legs 52 are provided on a TO5 base 51. In the first direction, all the legs 52 can be divided into two columns, each column includes two legs 52, and the lines connecting the two columns of legs 52 are parallel to each other; and in the second direction, all the legs 52 can also be divided into two columns, each column includes two legs 52, and the lines connecting the two columns of legs 52 are parallel to each other; Fig.12 It can be seen that the first direction and the second direction are perpendicular to each other, and two first grooves 742A1 are provided on the first separator 742A, and the first grooves 742A1 are strip-shaped and parallel to each other. Since the first separator 742A faces the first direction, when the first separator 742A is inserted toward the first direction, the two rows of tube legs 52 in the first direction respectively enter the two first grooves 742A1, so that all the tube legs 52 are limited in the second direction by the first separator 742A; two second grooves 742B1 are provided on the second separator 742B, and the second grooves 742B1 are strip-shaped and parallel to each other. Since the second separator 742B faces the second direction, when the second separator 742B is inserted toward the second direction, the two rows of tube legs 52 in the second direction respectively enter the two second grooves 742B1, so that all the tube legs 52 are limited in the first direction by the second separator 742B; thereby achieving circumferential limiting of all the tube legs 52.

[0099] The preset angle is consistent with the angle of the connection line of the upper edge tube legs 52 of the TO5.

[0100] Since both the first separator 742A and the second separator 742B need to be inserted into the TO5 tube leg 52, the first separator 742A and the second separator 742B need to be set at different levels. Fig.12It can be seen that, from a top-down perspective, when the first separator 742A and the second separator are inserted into the TO5 tube leg 52, the first groove 742A1 and the second groove 742B1 intersect with each other to form a plurality of limiting holes, framing each tube leg 52. Maintaining this state controls the connecting platform 72 on the first slide rail 11 to move vertically downward, thereby straightening the TO5 tube leg 52.

[0101] Embodiment 2:

[0102] Based on Example 1, this Example 2 provides another TO tube leg flexible placement device, which includes another separation mechanism 7 for solving the problem that the TO5 tube legs 52 are not arranged in a matrix on the base 51.

[0103] Embodiment 2 of the present invention provides a TO tube leg flexible placement device, comprising: a fixing frame 1, a nozzle tube 2, a transmission wheel group 3 and a motor 4, wherein:

[0104] The suction nozzle pipe 2 is rotatably arranged on the fixing frame 1 , the motor 4 is arranged on the fixing frame 1 , and the motor 4 and the suction nozzle pipe 2 are connected and linked via the transmission wheel set 3 .

[0105] In this embodiment, the suction nozzle tube 2 is a strip-shaped cylinder, one end of the suction nozzle tube 2 is connected to the vacuum pump, which is used to pressurize or reduce the inside of the suction nozzle tube 2. The front end of the suction nozzle tube 2 is provided with an opening connected to the vacuum pump, which is used to adsorb TO5. In this device, the front end of the suction nozzle tube 2 faces downward, and the middle part of the suction nozzle tube 2 is sleeved with the fixing platform 13 extending from the upper end of the fixing frame 1, and the fixing platform 13 is protruding relative to the vertical projection of the fixing frame 1; it is worth mentioning that the connection between the suction nozzle tube 2 and the fixing platform 13 is a rotatable sleeve, that is, on the basis of the sleeve, the suction nozzle tube 2 can be rotated in the fixing platform 13; the part of the suction nozzle tube 2 above the fixing platform 13 can be bent to save space and connect with the vacuum pump; it should be noted that when adsorbing TO5, the front end of the suction nozzle tube 2 is partially adsorbed with the base 51 of TO5 to ensure that the base 51 of TO5 is in contact with the front end of the suction nozzle tube 2, and the tube leg 52 of TO5 faces downward for subsequent insertion into the electrode holder 6.

[0106] In this embodiment, the motor 4 is arranged at the upper end of the fixed frame 1, and the lower end of the motor 4 is at the same horizontal height as the lower end of the fixed platform 13 used to sleeve the suction nozzle pipe 2. The transmission wheel group 3 is arranged at the lower end of the motor 4 and the lower end of the fixed platform 13, wherein the transmission wheel group 3 includes: a first transmission wheel 31, a second transmission wheel 32 and a transmission belt 33, the first transmission wheel 31 and the second transmission wheel 32 are linked by the transmission belt 33, the first transmission wheel 31 is arranged at the lower end of the fixed platform 13, and is used to be sleeved with the suction nozzle pipe 2, the second transmission wheel 32 is connected to the fixed shaft of the motor 4, and the second transmission wheel 32 is used to be driven by the motor 4 to rotate, thereby driving the first transmission wheel 31 to rotate synchronously; the first transmission wheel 31 is used to drive the suction nozzle pipe 2 to rotate synchronously, thereby achieving the effect of the motor 4 driving the suction nozzle pipe 2 to rotate.

[0107] The lower end of the suction nozzle tube 2 is used to adsorb TO5, and the motor 4 is used to rotate in forward and reverse directions at a preset cycle, driving the suction nozzle tube 2 and TO5 to rotate in forward and reverse directions synchronously. While TO5 rotates synchronously, the fixing frame 1 drives TO5 to insert into the electrode holder 6.

[0108] Among them, the rotation in the positive and negative directions is clockwise and counterclockwise rotation, and the preset period is set by a technician in this field. The preset period is set as short as possible. The effect achieved is that TO5 makes reciprocating clockwise and counterclockwise rotations in a short time, so that it simulates the action of human hand twisting, making it easier for the TO5 tube leg 52 to be inserted into the electrode holder 6. For example, in real life, people insert nails into holes by hand. In order to buffer the friction between the nail and the inner wall of the hole, the nail is usually inserted by human hand twisting to make the insertion process easier.

[0109] In the prior art, when inserting the TO5 tube leg 52 into the electrode holder 6, since the inner diameter of the socket of the electrode holder 6 is narrow and there may be a certain error in the positioning between the TO5 and the electrode holder 6, the insertion process may easily cause abutment and collision, or the friction between the TO5 tube leg 52 and the inner wall of the electrode holder 6 may cause damage to the TO5 tube leg 52, causing the TO5 tube leg 52 to bend or even break. According to actual production statistics, the scrap rate of TO5 products caused by the bending of the TO5 tube leg 52 is as high as 10%.

[0110] In this embodiment, a suction nozzle tube 2 is provided on the fixing frame 1 for sucking TO5, and a motor 4 is also provided on the fixing frame 1. The motor 4 is linked with the suction nozzle tube 2 through a transmission wheel group, and the fixing frame 1 is controlled to move TO5 to the corresponding electrode holder 6 position. In the process of inserting TO5 into the electrode holder 6, the suction nozzle tube 2 is controlled by the motor 4 to rotate back and forth, and the insertion action of TO5 is performed during the reciprocating rotation, thereby avoiding the damage or breakage of the TO5 tube leg 52 during the insertion process due to the friction between the inner wall of the electrode holder 6 and the TO5 tube leg 52.

[0111] Since the tube leg 52 of TO5 needs to be positioned and inserted into the electrode holder 6 later, TO5 needs to be accurately located at the center of the lower end of the suction nozzle tube 2. During the suction process of the suction nozzle tube 2 to suck TO5, TO5 is usually adsorbed from the feed tray, and the adsorption force cannot ensure that TO5 is accurately adsorbed at the center of the lower end of the suction nozzle tube 2. Therefore, this embodiment also involves the following designs:

[0112] The fixing frame 1 is further laterally provided with a first slide rail 11 ; at least two clamps 12 are slidably provided on the first slide rail 11 .

[0113] The front end of the clamp 12 extends to the horizontal height of the lower end of the suction nozzle tube 2, and the first slide rail 11 is used for the clamp 12 to move horizontally. The at least two clamps 12 are used to move to the corresponding positions of the lower end of the suction nozzle tube 2 respectively, and the front end of the clamp 12 is used to abut against the base 51 of TO5 to align the base 51.

[0114] In this embodiment, the first slide rail 11 is horizontally arranged at the middle position of the fixed frame 1, and the clamp 12 is arranged on the first slide rail 11. The first slide rail 11 controls the clamp 12 to move on the first slide rail 11 through the cylinder. The clamp 12 extends out of the fixed frame 1 in the horizontal direction to reach the vertical plane where the suction nozzle tube 2 is located, and then extends vertically downward to the horizontal height where the lower end of the suction nozzle tube 2 is located, and faces the vertical position of the suction nozzle tube 2. When the two clamps 12 move toward each other on the first slide rail 11, that is, the front ends of the two clamps 12 move toward the lower end of the suction nozzle tube 2, and abut against the base 51 of TO5 adsorbed at the lower end of the suction nozzle tube 2, so as to straighten the TO5 base 51 and position TO5. After positioning TO5, the two clamps 12 can move in the opposite direction on the first slide rail 11 to release the abutment against the TO5 base 51 to avoid interfering with the subsequent rotation of TO5.

[0115] The working process of the clamp 12 is as follows: after TO5 is adsorbed on the lower end of the nozzle tube 2, the two clamps 12 move toward each other synchronously on the first slide rail 11 until the front ends of the two clamps 12 abut against the TO5 base 51 to align the base 51, and then the two clamps 12 move back to back synchronously on the first slide rail 11 to release the abutment against the TO5 base 51.

[0116] It should be noted that since the outer contour of the base 51 of most TO5s is circular, in order to enable the front end of the clamp 12 to more accurately position and abut against the base 51, the front end of the clamp 12 in this embodiment is arc-shaped and matches the outer contour of the base 51.

[0117] Since some of the legs 52 of the TO5 may not be straight when the TO5 is just produced, and even different legs 52 may be connected together, which will greatly affect the process of inserting the TO5 into the electrode holder 6, before inserting the legs 52 of the TO5 into the electrode holder 6, it is necessary to separate the different legs 52 and straighten the legs 52. Therefore, this embodiment also involves the following designs:

[0118] The fixing frame 1 is provided with a separation mechanism 7, which comprises: a second slide rail 71, a connecting platform 72 and a separation assembly 74, wherein:

[0119] The second slide rail 71 is vertically arranged on the side of the fixing frame 1, the connecting platform 72 is slidably connected to the second slide rail 71, the separation component 74 is arranged at the lower end of the connecting platform 72, and the separation component 74 extends to the bottom of the suction nozzle tube 2; the second slide rail 71 is used to drive the separation component 74 to move in the vertical direction.

[0120] Among them, the second slide rails 71 are vertically arranged at the two sides of the fixing frame 1, and the two sides of the connecting platform 72 are slidably connected with the second slide rails 71 on both sides, that is, the connecting platform 72 is controlled by the cylinder to move vertically along the second slide rails 71, and the lower end of the connecting platform 72 is a platform for setting the separation component 74, and the lower end of the connecting platform 72 is slightly higher than the horizontal height of the lower end of the suction nozzle tube 2. At least two separation components 74 are arranged at the lower end of the connecting platform 72, and the connecting platform 72 is controlled by the second slide rails 71 to move in the vertical direction, thereby driving the lower end of the connecting platform 72 The separation component 74 is moved vertically synchronously; when straightening the TO5 tube legs 52, it is necessary to limit the respective tube legs 52 of the TO5 through the separation component 74, and move the separation component 74 vertically while keeping the limit, so that each TO5 tube leg 52 can be limited by the separation component 74 from top to bottom, thereby achieving the purpose of straightening. Therefore, no matter where the separation component 74 is set at the lower end of the fixed platform 13, the separation component 74 needs to be set in the vertical direction of the suction nozzle tube 2, and the separation component 74 needs to extend to the lower end of the suction nozzle tube 2.

[0121] The separation assembly 74 includes a slide 741 and a separator 742, wherein:

[0122] The slide 741 is arranged at the lower end of the connecting platform 72, and the separator 742 is arranged on the slide 741. The separator 742 extends to the bottom of the suction nozzle tube 2, and the slide 741 and the separator 742 are both arranged toward the vertical position where the suction nozzle tube 2 is located; the slide 741 is used to drive the separator 742 to move in the horizontal direction.

[0123] In this embodiment, the slide 741 includes a mounting base and a slide, the slide and the mounting base are slidably connected, and the slide is controlled by a cylinder to move on the mounting base. The separator 742 is arranged on the slide, and the slide is controlled by a cylinder to drive the separator 742 to move axially. The separator 742 is provided with grooves, each of which is aligned with each corresponding tube leg 52 on the TO5. The separator 742 moves axially toward or away from the TO5, and the tube leg 52 of the TO5 enters the corresponding groove or exits the corresponding groove, thereby limiting the corresponding tube leg 52; for all TO5, the root of the tube leg 52 is usually the most correct in shape and position. Therefore, if the TO5 tube leg 52 is straightened by the separator 742, it is best to start straightening from a position close to the root of the tube leg 52, and the root position of the tube leg 52 is at the top, so when the separation is performed. When straightening, first control the first slide rail 11 to move the front end of the separator 742 to the horizontal height of the upper end of the TO5 tube leg 52, and then control the second pneumatic slide groove to move each separator 742 axially toward the position of TO5, and each tube leg 52 on TO5 enters into the groove of the corresponding separator 742, thereby limiting the tube leg 52 on each TO5, and then control the first slide rail 11 to move the separator 742 vertically downward, and each tube leg 52 on TO5 is straightened or separated under the limiting action of the groove of the separator 742, and then control the second pneumatic slide groove to move each separator 742 axially toward the position away from TO5, so that each tube leg 52 on TO5 withdraws from the groove of the separator 742 to avoid subsequent influence on the insertion of the tube leg 52 into the electrode holder 6, and finally control the first slide rail 11 to move the separator 742 vertically upward to restore it to the initial position.

[0124] In this embodiment, considering that the tube legs 52 on the TO5 base 51 may not necessarily be distributed in a matrix or diamond shape, but may be distributed in other irregular ways, and the number of tube legs 52 is greater, it is impossible to ensure that the tube legs 52 on the TO5 base 51 are distributed in parallel columns. At this time, it is difficult to use strip-shaped grooves to limit a row of multiple tube legs 52 as in Example 1. When the number of tube legs 52 is too large, there may be too many columns of tube legs 52 in one direction, and each column of tube legs 52 requires a corresponding groove. At this time, too many grooves need to be set on the separator 742, resulting in excessive difficulty in designing the separator 742. Therefore, the separator 742 design in Example 1 is not suitable for the above situation. Therefore, this embodiment also involves the following designs:

[0125] like Fig.13 and Fig.14 As shown, at least two separation components 74 are arranged on the connecting platform 72, all the separation components 74 are arranged around the suction nozzle tube 2, and the separation tools 742 of all the separation components 74 are located at the same level.

[0126] like Fig.15 and Fig.16 As shown, at least two semicircular grooves 7421 are arranged on the front end face of each separator 742. When the front ends of all the separators 742 are abutted against each other, the semicircular groove 7421 on each separator 742 is matched with the semicircular groove 7421 on the adjacent separator 742 as a limiting circular groove 7422, and the limiting circular groove 7422 is used to accommodate the corresponding tube leg 52 on TO5.

[0127] The second slide rail 71 and the slide table 741 drive the separator 742 to reciprocate in the vertical and horizontal directions, so as to straighten the tube legs 52 on the TO5.

[0128] In this embodiment, four separation components 74 are provided, such as Figure 14-16As shown, since all separation components 74 need to be arranged around the lower end of the suction nozzle tube 2, in this embodiment, one side of the lower end of the connecting platform 72 protrudes and is arranged around the suction nozzle tube 2 half a circle, and the protruding end is used to set one of the separation components 74, and the other three separation components are relatively arranged at the lower end of the other side of the connecting platform 72. In this embodiment, the semicircular groove 7421 is a semicircular notch, which is arranged on the end face of the separator 742, and each semicircular groove 7421 is used to be combined with the semicircular groove 7421 of the adjacent separator 742 to form a limiting circle. Groove 7422, each limiting circular groove 7422 corresponds to the same tube leg 52. Considering that at least four tube legs 52 are arranged on a TO5, each tube leg 52 requires two semicircular grooves 7421 to be assembled to form a limiting circular groove 7422 for limiting. Therefore, at least 8 semicircular grooves 7421 are required. Every two semicircular grooves 7421 are arranged on a separator 742. All separators 742 are moved toward the lower end of the nozzle tube 2 and abut against each other to form a limiting groove. Therefore, the lower ends of all separators 742 need to be kept at the same horizontal height.

[0129] like Fig.16 As shown, five tube legs 52 are used as an example for explanation. In this embodiment, five tube legs 52 are arranged on the base 51 of TO5, and the connection line of the five tube legs 52 is a pentagon. It is difficult to use the separator 742 of embodiment 1 to limit all the five tube legs 52. In this embodiment, four separation components 74 are correspondingly arranged, wherein the edges of three separators 742 are all provided with two semicircular grooves 7421, and two semicircular grooves 7421 are arranged on both sides of a separator 742 at the opposite end, which are used to pair up to form a limiting circular groove 7422, and one constitutes four limiting circular grooves 7422, which are used to match the four tube legs 52 on TO5. The separator 742 at the opposite end is also provided with a strip groove, and the separator 742 in the opposite direction is provided with a corresponding boss. When the separator 742 at the opposite end abuts against the separator 742 opposite to it, the boss is inserted into the strip groove, but the boss is not inserted into the bottom of the strip groove, but a space is left as the fifth limiting circular groove 7422, which is used to correspond to the last tube leg 52 on TO5. The separator 742 is driven to reciprocate in the vertical and horizontal directions by the second slide rail 71 and the slide 741, so as to straighten the tube leg 52 on TO5; Fig.17 As shown, the separator 742 is Fig.17 Move in the order of arrows E, F, G and H to straighten the tube legs 52.

[0130] Embodiment 3:

[0131] Based on Embodiment 1 and Embodiment 2, this Embodiment 3 provides a TO tube leg flexible placement method, which is performed on the TO tube leg flexible placement device, such as Fig.18As shown, the method flow includes:

[0132] In step 101, the lower end of the suction nozzle tube 2 sucks TO5.

[0133] In step 102 , the base 51 of the TO5 is abutted by the clamp 12 provided on the fixing frame 1 , and the base 51 of the TO5 is aligned.

[0134] A first slide rail 11 is horizontally arranged on the fixing frame 1, and at least two clamps 12 are slidably arranged on the first slide rail 11. By moving the at least two clamps 12 in relative directions on the first slide rail 11, the front end of the clamp 12 is abutted against the base 51 of TO5, and the base 51 of TO5 is straightened.

[0135] In step 103 , the legs 52 of the TO5 are straightened by the separation mechanism 7 provided on the fixing frame 1 .

[0136] According to the number and distribution position of the tube legs 52 of TO5, the number and position of the grooves on the separator 742 of the separation mechanism 7 are set; the separator 742 is driven by the slide 741 of the separation mechanism 7 to move horizontally toward the horizontal position where TO5 is located, so as to limit the tube legs 52 of TO5;

[0137] The second slide rail 71 of the separation mechanism 7 drives the separation tool 742 to move vertically from top to bottom to straighten the tube legs 52 of the TO5.

[0138] In step 104 , the position of the electrode holder 6 is obtained according to the preset coordinate points, and TO5 is moved above the position of the electrode holder 6 .

[0139] In this embodiment, the fixing frame 1 first drives TO5 to move to the preset coordinate point according to the set preset coordinate point, and this position is the approximate position of the electrode seat 6. An image recognition lens is arranged next to the nozzle tube 2 for performing image recognition on the lower end of the nozzle tube 2. When TO5 moves to the preset coordinate point, the image recognition lens performs image recognition on the electrode seat 6 below to determine the similarity between the electrode seat 6 and the target electrode seat 6. When the similarity reaches the preset percentage, it represents that the electrode seat 6 is the target electrode seat 6, and the distance compensation is performed through the distance difference between the image recognition lens and the bottom of the nozzle tube 2 to move TO5 to the precise position of the center of the electrode seat 6. When the similarity is lower than the preset percentage, it represents that the electrode seat 6 is not the target electrode seat 6, and TO5 is moved to the next preset coordinate point.

[0140] In step 105 , the motor 4 drives the nozzle tube 2 and the TO5 to rotate in forward and reverse directions at a preset period. While the TO5 rotates synchronously, the fixing frame 1 drives the TO5 to be inserted into the corresponding electrode holder 6 .

[0141] After the insertion operation is completed, it is determined whether the TO5 tube leg 52 is inserted successfully. If successful, the process returns to step 101 . If unsuccessful, the process returns to step 101 after performing the material throwing operation.

[0142] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
