Description

Technical Field

[0001] The utility model relates to the field of rotary automatic assembly equipment, and particularly relates to a fuse riveting and assembling mechanism. Background Art

[0002] At present, rotary automatic assembly equipment has been widely used in the assembly of electronic components. There is a kind of fuse that needs to be assembled by rotary automatic assembly equipment. This fuse is also called a thermal fuse. For example, reference can be made to the "Thermosensitive Particle Type Thermal Fuse" with the Chinese utility model patent publication number CN111105964B and the "Wafer for Thermal Fuse and Its Thermal Fuse" with the Chinese utility model patent publication number CN203521349U. As Figure 11 shown, the above-mentioned fuse includes a fuse housing 98 and a lead 99. The lead 99 includes a conductive pin 991 and a ceramic sleeve 992. At present, the fuse housing 98 is inserted upright into a jig on the station turntable of the rotary automatic assembly equipment. In the subsequent processes of the rotary automatic assembly equipment, the internal parts of the fuse are loaded into the fuse housing 98 from top to bottom. The last process of fuse assembly is to load one end of the lead 99 into the fuse housing 98, and form a riveting shoulder 981 (necking) at the upper end of the fuse housing 98 to prevent the ceramic sleeve 992 from falling outwards. The conductive pin 991 and the ceramic sleeve 992 need to be pre-assembled together. When the lead 99 is sorted and output by a vibrating bowl, since one end of the conductive pin 991 that is relatively far from the ceramic sleeve 992 is a smooth shaft structure, it is difficult for the vibrating bowl to output the lead 99 in an inverted manner as Figure 11 shown. That is to say, when the output track of the vibrating bowl outputs the lead 99, the ceramic sleeve 992 is hung. Since the vibrating bowl can only output the lead 99 upright, currently, the rotary automatic assembly equipment cannot install the lead 99 into the fuse housing 98. Instead, the semi-finished fuse assembled by the rotary automatic assembly equipment needs to be taken out into a tooling, taken to a separately arranged riveting device, and the lead 99 sorted and output by combining the vibrating bowl and a linear vibrator is inverted and inserted into the fuse housing 98 by hand, and then the riveting shoulder 981 is formed through the riveting device. Although the vibrating bowl combined with the linear vibrator can output the lead 99 in a multi-row side-by-side manner and can eliminate the operation of manually picking out the lead 99 from the scattered lead pile, making the actions of workers loading the lead 99 unified, the labor intensity is still relatively large, and the manual operation efficiency is related to the proficiency and current mental state of the workers, resulting in being not conducive to improving production efficiency. Therefore, it is necessary to make a feeding and riveting mechanism for the above-mentioned lead 99 so that the lead 99 can also be assembled by the rotary automatic assembly equipment.

Detailed implementation manners

[0023] The following further describes the present utility model with reference to the accompanying drawings.

[0024] The fuse riveting and assembling mechanism of the present utility model, as Figure 1 and Figure 2 shown, includes a feeding component 1. The feeding component 1 includes a rotary disk 11 rotatably arranged above the station turntable component 3 around a horizontal axis. In other words, the rotary disk 11 is erected. The rotation axis of the rotary disk 11 is vertically intersected with the rotation axis of the station turntable component 3. Among them, the station turntable component 3 includes a fixed disk and a movable disk. The fixed disk is located above the movable disk. The movable disk is installed on the first cam divider. The feeding component 1 includes a support. The above - mentioned support is installed on the above - mentioned fixed disk. The feeding component 1 includes a motor component 16. The motor component 16 is drivingly connected to the rotary disk 11. The motor component 16 is installed on the above - mentioned support. The feeding component 1 further includes a second cam divider. The rotary disk 11 is installed on the second cam divider. The motor component 16 drives the rotary disk 11 to rotate by indexing through the second cam divider. The motor component 16 can be a stepper motor or a servo motor.

[0025] As Figure 2As shown, the loading component 1 includes a loading manipulator 13 and a picking component 14 for transferring the lead 99 at the end of the linear vibrator to the corresponding upper side of the flipping disk 11. As Figure 3 shown, the picking component 14 is provided with a jacket 141 for clamping the ceramic sleeve 992 of the lead 99. For example, the outer shape of the jacket 141 is generally cylindrical. A clamping cavity for accommodating the ceramic sleeve 992 is formed at the lower end of the jacket 141. The jacket 141 is formed with a slit, and the above-mentioned slit penetrates the above-mentioned clamping cavity. As Figure 2 shown, the loading manipulator 13 is drivingly connected to the picking component 14. Specifically, the loading manipulator 13 includes a radial movement seat and a vertical movement seat. A bracket is installed on the upper side of the second cam divider. The radial movement seat is slidably connected to the upper end of the above-mentioned bracket through a corresponding linear guide pair. The vertical movement seat is slidably connected to one end of the radial movement seat through a corresponding linear guide pair. The loading manipulator 13 further includes a radial movement cylinder and a vertical movement cylinder. The radial movement cylinder drives the radial movement seat to move along a direction parallel to the rotation axis of the flipping disk 11, and the vertical movement cylinder drives the vertical movement seat to move up and down. The jacket 141 is relatively fixedly installed on one side of the vertical movement seat.

[0026] As Figure 2 and Figure 4 shown, the flipping disk 11 is provided with a pick-and-place component 12 for transferring the lead 99 from the picking component 14 to the fuse housing 98. Two sets of pick-and-place components 12 are distributed around the rotation axis of the flipping disk 11 at 180°. As Figures 2 to 4 shown, the pick-and-place component 12 includes a radial slide seat 121 and a pick-and-place cylinder 122. The pick-and-place cylinder 122 is drivingly connected to the radial slide seat 121. The radial slide seat 121 is slidably connected to the flipping disk 11 through a corresponding linear guide pair. The "radial" in the "radial slide seat 121" is with respect to the rotation axis of the flipping disk 11. In other words, the radial slide seat 121 slides in a plane perpendicular to the rotation axis of the flipping disk 11. The cylinder block of the pick-and-place cylinder 122 is installed on the flipping disk 11, and the piston rod of the pick-and-place cylinder 122 is installed and connected to the radial slide seat 121. As Figure 1 shown, the second cam divider and the pick-and-place component 12 are respectively located on both sides of the flipping disk 11. Among them, the second cam divider is relatively close to the central axis of the station turntable component 3, while the pick-and-place component 12 is relatively far from the central axis of the station turntable component 3. As Figure 5 and Figure 6 shown, the pick-and-place component 12 includes a loading sleeve 123 for accommodating the conductive pin 991 of the lead 99. In other words, since the loading sleeve 123 and the conductive pin 991 are in clearance fit, the ceramic sleeve 992 cannot enter the loading sleeve 123. The loading sleeve 123 is correspondingly arranged in the radial slide seat 121. As Figure 10As shown, a socket cavity 1210 for the upper end of the fuse housing 98 in the fixture 31 on the station turntable assembly 3 to be inserted in a fitting manner is provided at the radially outer end of the radial slide 121 (the "radially outer end" mentioned here is with respect to the rotation axis of the turning plate 11. In other words, the socket cavity 1210 is located at the end of the radial slide 121 relatively far from the rotation axis of the turning plate 11), and a formed inner fillet 1211 for contacting the upper edge of the fuse housing 98 is formed at the bottom of the socket cavity 1210.

[0027] The working principle of the fuse riveting and assembling mechanism of the present utility model will be briefly described below: As Figure 1 shown, a number of fixtures 31 are evenly distributed on the movable plate of the station turntable assembly 3, and the fixtures 31 are located outside the fixed plate of the station turntable assembly 3. As Figure 10 shown, the fuse housing 98 is inserted on the fixture 31. Specifically, four fuse housings 98 are arranged at equal intervals along the chord direction of the movable plate of the station turntable assembly 3 on the fixture 31, and the opening of the fuse housing 98 is upward. When the fixture 31 reaches the station corresponding to the feeding assembly 1, the relevant parts of the fuse have been loaded into the fixture 31. For the convenience of viewing, Figure 10Parts other than the fuse housing 98 and the lead wire 99 of the fuse are not shown. The vibrating bowl combined with the linear vibrator arranged outside the station turntable assembly 3 arranges and outputs the lead wire 99. During this period, the lead wire 99 is in an upright state, that is, the conductive pin 991 stands upright and the ceramic sleeve 992 is located at the upper end of the conductive pin 991. The loading manipulator 13 drives the clamping sleeve 141 to move above the end of the linear vibrator. The loading manipulator 13 moves the clamping sleeve 141 downward so that the clamping cavity at the lower end of the clamping sleeve 141 sleeves outside the ceramic sleeve 992. As mentioned above, since the clamping sleeve 141 is formed with a slit, the clamping cavity of the clamping sleeve 141 will elastically open, thereby clamping the ceramic sleeve 992. The number of clamping sleeves 141 is four, and the four clamping sleeves 141 are equally spaced in the horizontal plane, so four lead wires 99 can be clamped simultaneously. Then the loading manipulator 13 moves the lead wire 99 upward and transfers it above the flipping disk 11 (that is, reaches the position where the material is to be taken). The flipping disk 11 is in a paused state during the indexing rotation process. The pick-and-place cylinder 122 of the pick-and-place component 12 at the upper position pushes the radial sliding seat 121 upward (that is, outward). Then the loading sleeve 123 of the radial sliding seat 121 moves upward, so that the conductive pin 991 of the lead wire 99 clamped by the clamping sleeve 141 can be relatively inserted into the corresponding loading sleeve 123. The lead wire 99 leaves the clamping sleeve 141. Then the pick-and-place cylinder 122 moves the radial sliding seat 121 downward to reset. The flipping disk 11 rotates. When the pick-and-place component 12 at the upper position mentioned above rotates 180° by indexing, the lead wire 99 in the loading sleeve 123 is flipped 180° (that is, turned upside down). That is, the flipping disk 11 is used to perform the up-and-down turning operation on the lead wire 99. Then the pick-and-place cylinder 122 pushes the radial sliding seat 121 outward (that is, downward) again. Since the lead wire 99 has been changed to an inverted state at this time, as Figure 10 shown, the end of the lead wire 99 with the ceramic sleeve 992 is inserted into the corresponding fuse housing 98. Subsequently, the upper end of the fuse housing 98 is inserted relatively upward into the sleeve cavity 1210 of the radial sliding seat 121. When the upper end edge of the fuse housing 98 contacts the formed inner fillet 1211 at the bottom of the sleeve cavity 1210, the formed inner fillet 1211 guides the upper end edge of the fuse housing 98 to bend inward and contract, so that the upper end of the fuse housing 98 forms Figure 11The riveting shoulder 981 shown in the figure completes the riveting assembly of the fuse housing 98 and the lead 99. Then, the pick-and-place cylinder 122 pulls the radial slide 121 inward (i.e., upward). Since the riveting shoulder 981 blocks the upward movement of the lead 99, the upper end of the fuse housing 98 is separated from the sleeve cavity 1210 and the conductive pin 991 is separated from the loading sleeve 123. During the process of inserting the lead 99 into the fuse housing 98 by the radial slide 121, a set of pick-and-place components 12 currently located in the upper position obtains the lead 99 in the picking component 14. In other words, since two sets of pick-and-place components 12 are distributed at 180° around the rotation axis of the turntable 11, the mechanism combining the turntable 11 and the pick-and-place components 12 can simultaneously perform the "pick" and "place" operations on the lead 99, which is beneficial to improving the work efficiency. After the radial slide 121 of the pick-and-place component 12 currently located in the lower position moves upward away from the fixture 31 of the station turntable assembly 3, the station turntable assembly 3 rotates the next fixture 31 to the corresponding station of the feeding component 1, and so on. As can be seen from the above, by setting the fuse riveting and assembling mechanism of the present invention, it is beneficial to realize the mechanized inverted feeding of the lead 99, and it is beneficial to enable the lead 99 to be assembled by a rotary automatic assembly device, thereby improving the production efficiency of the fuse. Moreover, since the fuse riveting and assembling mechanism of the present invention can replace manual operation, it is beneficial to reduce the labor intensity of workers and is beneficial to safe production.

[0028] Further, as Figure 6 shown, the loading sleeve 123 is slidably connected to the radial slide 121. The sliding direction of the loading sleeve 123 relative to the radial slide 121 is parallel to the sliding direction of the turntable 11 relative to the radial slide 121. Specifically, a blind hole with a clearance fit with the loading sleeve 123 is formed in the radial slide 121. A buffer spring 1231 is provided in the radial slide 121. The radially outer end of the buffer spring 1231 is in contact connection with the radially inner end of the loading sleeve 123 (the "radially outer end" and "radially inner end" mentioned here are with respect to the rotation axis of the turntable 11). The radially inner end of the buffer spring 1231 is in contact connection with the bottom of the above-mentioned blind hole. Thus, as Figure 10 shown, when the pick-and-place cylinder 122 pushes the radial slide 121 downward to insert the lead 99 into the fuse housing 98, as Figure 11 shown, since a step for blocking and contacting the ceramic sleeve 992 is formed on the inner wall of the fuse housing 98, when the ceramic sleeve 992 moves down to the above-mentioned step, the ceramic sleeve 992 cannot continue to move down. However, since the buffer spring 1231 can be elastically compressed and deformed, the radial slide 121 can continue to move downward by a certain amplitude. That is to say, the buffer spring 1231 can buffer the impact, avoid damage to the above-mentioned step, and also reduce the requirements for the manufacturing precision and assembly precision of the parts of the rotary automatic assembly device. As Figure 10As shown, since the material loading sleeve 123 can retract inward to make way, when the formed inner fillet 1211 moves downward to press the upper edge of the fuse housing 98, the above-mentioned step will not be damaged. When the radial slide 121 moves back toward the rotation axis of the turning disk 11, the material loading sleeve 123 moves outward and resets through the elastic restoring force of the buffer spring 1231, as Figure 6 shown, the shoulder at the outer end of the material loading sleeve 123 is blocked by the internal structure of the radial slide 121, thus preventing the material loading sleeve 123 from falling out outward.

[0029] Furthermore, as Figure 6 shown, the pick-and-place component 12 includes a positioning pin 124 for contacting the conductive pin 991 along the radial direction of the conductive pin 991. The pick-and-place component 12 includes a positioning spring 1241 for pushing the positioning pin 124 toward the conductive pin 991. One end of the positioning spring 1241 is in contact connection with one end of the positioning pin 124, and the other corresponding end of the positioning spring 1241 is in contact connection with a spring pressure plate. Among them, both ends of the above-mentioned spring pressure plate are installed and connected to the radial slide 121, as Figure 7 shown, a notch 1230 for avoiding the positioning pin 124 is formed on one side of the material loading sleeve 123, as Figure 6 shown, the positioning pin 124 can reach the cylindrical outer wall of the conductive pin 991 only when it extends into the notch 1230. Through the above setting, a frictional resistance is generated between the end of the positioning pin 124 and the cylindrical outer wall of the conductive pin 991, preventing the lead wire 99 from being thrown outward due to the centrifugal force during the rotation of the turning disk 11. When the material loading sleeve 123 moves toward the conductive pin 991 of the lead wire 99 located on the clamping sleeve 141, when the conductive pin 991 is relatively inserted into the material loading sleeve 123, the conductive pin 991 can push aside the positioning pin 124. In other words, the elastic force of the positioning spring 1241 on the positioning pin 124 is set to be relatively small. Similarly, as Figure 10 shown, when the material loading sleeve 123 moves upward and disengages from the already assembled lead wire 99, the conductive pin 991 can slide away from the end of the positioning pin 124. A guiding chamfer or guiding fillet is formed at the end of the above-mentioned positioning pin 124.

[0030] Furthermore, as Figure 2 and Figure 3 shown, the feeding component 1 includes a conductive pin straightening component 15. The conductive pin straightening component 15 includes a fixedly arranged clamping finger cylinder 152. The conductive pin straightening component 15 includes a clamping plate 151 for the conductive pin 991 to fit through from top to bottom. The clamping finger cylinder 152 drives the clamping plate 151 to open and close. Specifically, the cylinder body of the clamping finger cylinder 152 is fixedly installed on the above-mentioned bracket. The number of clamping finger cylinders 152 is set to two, and the number of clamping plates 151 is two. The two clamping plates 151 are horizontally symmetrically arranged. In Figure 3In the visual direction, the two fingers of the clamping finger cylinder 152 located on the left side are respectively installed and connected to the left ends of the two clamping plates 151, and the two fingers of the clamping finger cylinder 152 located on the right side are respectively installed and connected to the right ends of the two clamping plates 151. A through hole extending in the up and down direction is formed at the joint of the two clamping plates 151. That is to say, when the two clamping plates 151 are opened relatively, the above through hole is separated into two halves. The conductive pin 991 is specifically adapted to pass through the above through hole from top to bottom, and a funnel structure for guiding the conductive pin 991 is formed at the upper end of the above through hole. As Figure 3 shown, the picking component 14 is provided with a push pin 1421 for pushing the lead 99 downward away from the collet 141. The push pin 1421 is coaxially and slidably arranged in the collet 141. That is to say, the above-mentioned slit may not be formed at the upper end of the collet 141, so the push pin 1421 and the upper end of the collet 141 are in clearance fit. The picking component 14 is provided with a push pin cylinder 142, and the push pin cylinder 142 is drivingly connected to the push pin 1421. Specifically, the cylinder block of the push pin cylinder 142 is installed on one side of the above-mentioned vertical moving seat, and the piston rod of the push pin cylinder 142 is connected to the upper end of the push pin 1421 through a mounting block. When the loading manipulator 13 drives the picking component 14 to insert the lead 99 downward in a positive position into the corresponding above through hole, the clamping plate 151 straightens the lead 99, so that the conductive pins 991 of each lead 99 are all in the up and down direction. At this time, the collet 141 reaches the "position to pick up materials" described above. Then the radial sliding seat 121 (and the loading sleeve 123) moves upward, so that the conductive pins 991 are relatively inserted into the corresponding loading sleeves 123. Since each conductive pin 991 is being straightened by the two clamping plates 151, each conductive pin 991 can be accurately inserted into the corresponding loading sleeve 123. After that, the clamping finger cylinder 152 drives the two clamping plates 151 to open, and the push pin cylinder 142 drives the push pin 1421 to move downward. The lower end of the push pin 1421 pushes the upper end of the lead 99 to push the ceramic sleeve 992 downward away from the collet 141. Since the two clamping plates 151 have been opened, the ceramic sleeve 992 can pass downward between the two clamping plates 151, so that the lower end of the ceramic sleeve 992 abuts against the upper end surface of the loading sleeve 123. During this process, the buffer spring 1231 also plays a buffering role. Then the push pin 1421 moves upward to reset, and the two clamping plates 151 are closed and reset to restore the structure of the above through hole.

[0031] Furthermore, as Figure 1 shown, the fuse riveting and assembling mechanism of the present invention further includes a riveting component 2. As Figure 8As shown, the press riveting assembly 2 includes a press arm 22 disposed outside the station turntable assembly 3. The press arm 22 is slidably arranged up and down. Specifically, the press arm 22 is connected to the machine table (it should be noted that the machine table mentioned above is not shown in each drawing) through a corresponding linear guide pair. The press riveting assembly 2 is provided with a press riveting cylinder 23, and the press riveting cylinder 23 drives the press arm 22 to move up and down. Specifically, the piston rod of the press riveting cylinder 23 is connected to the lower end of the press arm 22, as Figure 8 and Figure 9 shown, the upper end of the press arm 22 is provided with a press head 21 for contact pressing the radial slide seat 121 located at a lower position. Specifically, an elbow is formed at the upper end of the press arm 22, and the press head 21 is installed on the above-mentioned elbow. When the press riveting cylinder 23 raises the press arm 22 to the highest position, the above-mentioned elbow extends between the two radial slide seats 121, so the rotation of the turntable 11 will not cause the above-mentioned elbow and press head 21 to collide with the radial slide seat 121. As Figure 9 shown, when the pick-and-place cylinder 122 pushes the radial slide seat 121 downward, the press riveting cylinder 23 also drives the press arm 22 to move downward. Immediately, the pry arm driving cylinder 25 installed on the press arm 22 horizontally drives the push wheel 24 to move upward to the upper end of the pry arm 125. The middle part of the pry arm 125 is hinged to the radial slide seat 121, as Figure 6 shown, the lower end of the pry arm 125 extends between the head of the positioning press pin 124 and the radial slide seat 121. So when the push wheel 24 pushes the upper end of the pry arm 125, the lower end of the pry arm 125 pries the positioning press pin 124 outward, so that the positioning press pin 124 is disengaged from the notch 1230 of the loading sleeve 123 outward, avoiding the edge of the notch 1230 from colliding with the positioning press pin 124 when the loading sleeve 123 retracts inward. Then the formed inner fillet 1211 contacts the upper edge of the fuse housing 98, as Figure 9 shown, the press head 21 contacts the upper end of the radial slide seat 121 and applies a downward pressure to the radial slide seat 121, so that the upper edge of the fuse housing 98 is plastically deformed and bent inward to form a riveting shoulder 981. In other words, the press riveting assembly 2 plays a role in collaborative riveting. When the press head 21 works, the press head 21 is located directly above the corresponding fixture 31, which is beneficial to making the four fuse housings 98 receive approximately the same force. After the fuse is assembled, the press riveting cylinder 23 drives the press arm 22 to move up and reset. Immediately, the radial slide seat 121 currently located at the lower position retracts and moves back to its original position. The pry arm driving cylinder 25 also drives the push wheel 24 to reset. The positioning spring 1241 drives the pry arm 125 and the positioning press pin 124 to reset. Since the space on the turntable 11 is limited and it is not convenient to set a pick-and-place cylinder 122 with a larger cylinder diameter, by setting the press riveting assembly 2, it is beneficial to increase the riveting force.
