Technical Field

[0001] The utility model relates to the technical field of patch processing, in particular to a patch processing positioning device. Background Art

[0002] SMT patch processing, the full name of which is surface mount technology, is an electronic assembly technology that directly attaches and solders electronic components to printed circuit boards. The core function of SMT patch processing is component placement. It can accurately and quickly place various electronic components on the predetermined positions on printed circuit boards. The application field of SMT patch processing is very wide, covering almost all electronic industries, such as automobiles, medical treatment, industrial automation, smart homes, etc. In the process of patch processing of circuit boards, positioning devices are required to position them, and electronic components are misplaced during the placement process.

[0003] In the current existing technology, during the process of mechanical positioning of the circuit board, the relative positioning between the supporting base and the circuit board is achieved by the mutual engagement between the ejector pins fixedly installed on the base plate supporting the circuit board and the holes on the circuit board, so that the circuit board can be transported to the electronic component application area for patch structure as the support moves. However, the relative position of the ejector pins on the supporting base plate is fixed and cannot be changed arbitrarily. Therefore, when the specifications of the circuit board change, it is necessary to replace the ejector pins and the support corresponding to the through holes on it to support it in half, resulting in poor applicability of the supporting base plate.

[0004] Therefore, a patch processing positioning device is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the relative position of the ejector pins on the supporting base is fixed and cannot be changed arbitrarily, which requires replacing the ejector pins and the supports corresponding to the through holes on them in half to support them when the specifications of the circuit board change, resulting in poor applicability of the supporting base, a patch processing positioning device is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a patch processing positioning device of the utility model includes a conveying base, rollers are installed inside both sides of the conveying base, a conveying frame is installed above the two rollers, slider openings are symmetrically opened on both sides of the conveying frame, and supporting slides are symmetrically installed inside the conveying frame, the two ends of the supporting slide are respectively passed through to the interior of the two slider openings, the outside of the supporting slide is symmetrically covered with a push rod base, the top center of the push rod base is vertically fixed with a limiting push pin, one end of the supporting slide is fixed with a matching slide, the matching slide is slidably installed inside one of the slider openings, the other end of the supporting slide is fixed with a first threaded sleeve, and a linkage component is provided on one side of the two push rod bases.

[0007] Preferably, the outer portion of the limiting ejector pin is sheathed with an ejector sleeve.

[0008] Preferably, a first bidirectional screw is provided on one side of the conveying base, and both ends of the first bidirectional screw are fixed with first brackets through bearings, and the two first brackets are fixed to the two ends of the side wall of the conveying base.

[0009] Preferably, the external threads at both ends of the first bidirectional screw rod respectively fit with the two first threaded sleeves.

[0010] Preferably, a first rubber clamp is installed at the center of one side of the conveying base, and the inner walls on both sides of the first rubber clamp are in contact with the central circular plate of the first bidirectional screw rod.

[0011] Preferably, the linkage assembly includes a second bidirectional screw rod, and the external threads at both ends of the second bidirectional screw rod are both sleeved with second threaded sleeves, and the two second threaded sleeves are respectively fixed to the two push rod bases.

[0012] Preferably, both ends of the second bidirectional screw are fixedly connected to second brackets via bearings, and the two second brackets are fixedly connected to both ends of the side walls of the supporting slide.

[0013] Preferably, a second rubber clamp is fixed at the center of the side wall of the supporting slide, and the inner walls on both sides of the second rubber clamp are in contact with the central circular plate of the second bidirectional screw rod.

[0014] Beneficial effects of the utility model:

[0015] 1. In the utility model, the slider opening of the side plate of the transmission frame cooperates with the supporting slide plate so that it can change its position in the longitudinal direction under the limitation of the slider opening. The ejector base is sleeved on the outside of the supporting slide plate, which enables it to change its position in the lateral direction under the limitation of the supporting slide plate. The ejector base positions the circuit board by clamping between the limiting ejector pins and the through holes on the circuit board. This enables the limiting ejector pins to be clamped with the through holes on the circuit board within a certain range when the circuit specifications change, thereby realizing the positioning of the circuit board and increasing the applicability of the device.

[0016] 2. In the present invention, since the through holes on the circuit board are mostly symmetrically arranged, the supporting slide plate and the ejector base, which are linked in cooperation with the first bidirectional screw rod and the second bidirectional screw rod, can be synchronously displaced and adjusted, thereby improving the work efficiency in the process of adjusting the position of the limit ejector pin.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 4The utility model provides a patch processing positioning device, including a conveying base 1, rollers 11 are installed on both sides of the conveying base 1, and a conveying frame 2 is installed above the two rollers 11. Slide openings 21 are symmetrically opened on both sides of the conveying frame 2, and a supporting slide 3 is symmetrically installed inside the conveying frame 2. The two ends of the supporting slide 3 are respectively passed through the interior of the two slide openings, and the outside of the supporting slide 3 is symmetrically covered with a push rod base 4. The top center of the push rod base 4 is vertically fixed with a limited ejector pin 41, one end of the supporting slide 3 is fixed with a matching slide 31, and the matching slide 31 is slidably installed in the interior of one of the slide openings 21. The other end of the supporting slide 3 is fixed with a first threaded sleeve 32, and a linkage group is provided on one side of the two push rod bases 4. Part 5, the conveying frame 2 is placed above the roller 11 in the conveying base 1, so that the conveying frame 2 as a whole can move radially under the rotation of the roller 11, and the conveying frame 2 is installed on the supporting slide 3 through the opening of the supporting slide 3, and the supporting slide 3 at its two ends fits the slider 31 and the first threaded sleeve 32 and the slider opening 21. It is limited so that it can only change its position vertically, while the ejector base 4 mounted on the outside of the supporting slide 3 can only move horizontally, which makes the limiting ejector pin 41 on the ejector base 4 that can be clamped with the circuit board through-hole change within a certain range according to the position change of the circuit board through-hole, ensuring its function of clamping and fixing the circuit board within a certain range, and the linkage component 5 can control the longitudinal movement of the two supporting slides 3;

[0027] like Figure 4 As shown, the outer portion of the limiting ejector pin 41 is covered with an ejector sleeve 6. When the aperture of the circuit board changes, the ejector sleeve 6 that can be clamped with the limiting ejector pin 41 can ensure that the limiting ejector pin 41 can be clamped and positioned on the circuit board through-hole.

[0028] like Figure 2 、 Figure 3 and Figure 4 As shown, a first bidirectional screw rod 22 is provided on one side of the conveying base 1, and first brackets 23 are fixed to both ends of the first bidirectional screw rod 22 through bearings. The two first brackets 23 are fixed to the two ends of the side wall of the conveying base 1, and the external threads at both ends of the first bidirectional screw rod 22 are fitted with two first threaded sleeves 32 respectively. A first rubber clamp 24 is installed at the center of one side of the conveying base 1, and the inner walls of both sides of the first rubber clamp 24 are fitted with the central circular plate of the first bidirectional screw rod 22, and the first bracket 23 fixes the first bidirectional screw rod 22. When the position of the supporting slide 3 needs to be adjusted, the first rubber clamp 24 is disengaged from the first bidirectional screw rod 22, and then the first bidirectional screw rod 22 is rotated, and the positions of the first threaded sleeve 32 and the supporting slide 3 change accordingly. When the position adjustment is completed, the first rubber clamp 24 is made to resume the clamping effect on the first bidirectional screw rod 22. At this time, the relative position of the supporting slide 3 will not change.

[0029] like Figure 2 and Figure 4 When the second screw rod 51 is in the state of being rotated and engaged with the slider 31, the second screw rod 51 and the second support pin 4 are fixed on the second support pin 4.

[0030] Working principle: The conveying frame 2 is placed above the roller 11 inside the conveying base 1, so that the conveying frame 2 as a whole can move radially under the rotation of the roller 11, and the conveying frame 2 is installed on the supporting slide 3 through the opening of the supporting slide 3, and the supporting slide 3 at its two ends fits the slider 31 and the first threaded sleeve 32 and the slider opening 21, so that it can only change its position longitudinally up and down, and the ejector base 4 mounted on the outside of the supporting slide 3 can only move laterally, which makes the limiting ejector pin 41 on the ejector base 4 that can be clamped with the circuit board through-hole change within a certain range according to the position change of the circuit board through-hole, ensuring its function of clamping and fixing the circuit board within a certain range, and the linkage component 5 can control the longitudinal movement of the two supporting slides 3. When the aperture of the circuit board changes, the ejector sleeve 6 that can be clamped with it on the limiting ejector pin 41 can ensure that the limiting ejector pin 41 is clamped and positioned on the circuit board through-hole. The first bracket 23 fixes the first bidirectional screw rod 22. When the position of the supporting slide 3 needs to be adjusted, the first rubber clamp 24 is disengaged from the first bidirectional screw rod 22, and then the first bidirectional screw rod 22 is rotated, and the positions of the first threaded sleeve 32 and the supporting slide 3 are changed accordingly. When the position adjustment is completed, the first rubber clamp 24 resumes its clamping effect on the first bidirectional screw rod 22. At this time, the relative position of the supporting slide 3 does not change, and the second bracket 53 fixes the second bidirectional screw rod 51 to the side wall of the supporting slide 3. When the position of the ejector base 4 needs to be adjusted, the second rubber clamp 54 is disengaged from the second bidirectional screw rod 51, and then the engaging slider 31 is rotated, and the second threaded sleeve 52 and the ejector base 4 are rotated accordingly. When the position adjustment of the ejector base 4 is completed, the second rubber clamp 54 resumes its clamping effect on the second bidirectional screw rod 51. At this time, the position of the ejector base 4 and its upper limit ejector pin 41 does not change.
