[0043] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0044] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0045] The embodiment of the present invention provides a single-double frame ejection device for a material box of a die bonder, see Figures 1 to 4 The pushing device includes a supporting mainboard 101, the side of the supporting mainboard 101 is fixedly connected to the external fixing plate 102, the external fixing plate 102 is fixedly installed on the crystal bonding machine equipment, and pushing mechanisms 200 are respectively installed on both sides of the supporting mainboard 101 for completing the pushing of a single or double frame. The pushing mechanism 200 includes a motor 201, a driving wheel 203, a pushing plate 205 and a frame pushing piece 209. The motor 201 is fixedly installed on the supporting mainboard 101, and the output end of the motor 201 is coaxially fixed with the driving wheel 203. The outer circumferential surface of the driving wheel 203 overlaps the outer circumferential surface of the driving roller 406. The driving roller 406 is rotatably installed on the supporting mainboard 101. The outer circumferential surface of the driving roller 406 overlaps the upper surface of the pushing plate 205, which is used to drive the pushing plate 205 to slide back and forth in the horizontal direction. The end of the pushing plate 205 away from the driving roller 406 is fixedly installed with a frame pushing piece 209.

[0046] Three groups of driven roller groups 500 are installed on the supporting main board 101. The driven roller groups 500 include driven rollers 506 that can rotate along the axis and roller grooves 507 that are annularly opened on the outer surface of the driven rollers 506. The driven rollers 506 and roller grooves 507 in two groups of driven roller groups 500 are used to clamp the lower surface of the push plate 205, and the driven rollers 506 and roller grooves 507 in the other group of driven roller groups 500 are used to clamp the upper surface of the push plate 205. The axes of the two driven rollers 506 located below the push plate 205 are respectively located on both sides of the vertical plane where the axis of the active roller 406 is located. A floating component 300 is arranged below the driven rollers 506 and the roller grooves 507 clamped with the upper surface of the push plate 205. The floating component 300 is installed at the bottom of the supporting main board 101 to maintain the horizontal state of the push plate 205.

[0047] Among them, the motor 201 is installed on the supporting main board 101 through the motor mounting plate 202. The motor mounting plate 202 has a circular contour and a plurality of mounting holes are evenly opened along the circumference of the motor mounting plate 202. This structure enables the position of the motor 201 to be adjusted arbitrarily along the circumference of the motor mounting plate 202 during installation, thereby ensuring that the outer circumferential surface of the driving wheel 203 just overlaps with the outer circumferential surface of the driving roller 406 after installation, which reduces the difficulty of debugging the equipment and can greatly improve work efficiency.

[0048] The width of the push plate 205 is equal to the width of the roller groove 507 . This structure enables the push plate 205 to be exactly arranged in the roller groove 507 , thereby realizing the limitation of the push plate 205 in the width direction by the roller groove 507 .

[0049] Among them, the two motors 201 located on both sides of the supporting main board 101 can respectively drive the pushing mechanism 200 located on the same side, so as to realize the independent control of the two pushing plates 205 located on the front and rear sides of the supporting main board 101, so that the equipment can flexibly adapt to the pushing of single frame or double frame, thereby meeting the production needs of multiple scenarios.

[0050] Through the above-mentioned structure, the present embodiment enables the two groups of pushing mechanisms 200 located on the front and rear sides of the supporting main board 101 to be driven and controlled separately, so that the equipment can flexibly adapt to the pushing of a single frame or a double frame, thereby meeting the production needs; in addition, through the mutual cooperation of the two groups of driven roller groups 500 located below the push plate 205 and the active roller 406, the stability of the active roller 406 driving the push plate 205 during the reciprocating motion is guaranteed, so as to better control the movement stroke of the push plate 205; through the mutual cooperation of a group of driven roller groups 500 located above the push plate 205 and the floating component 300, the horizontal state of the push plate 205 during the reciprocating motion is maintained, so that the equipment can push the material into place with higher accuracy and stronger stability when pushing the material over a long distance.

[0051] For further explanation of the present invention, see Figures 1 to 5 The pushing mechanism 200 further includes an avoidance groove 208, a first photoelectric sensor 210, and a second photoelectric sensor 211. The upper and lower surfaces of the frame pushing member 209 are respectively provided with avoidance grooves 208 for avoiding the side edge of the driven roller 506;

[0052] A first photoelectric sensor 210 is fixedly installed on the first side of the supporting main board 101, and a second photoelectric sensor 211 is fixedly installed on the second side of the supporting main board 101. The first photoelectric sensor 210 and the second photoelectric sensor 211 are horizontally aligned, and the first photoelectric sensor 210 and the second photoelectric sensor 211 are respectively connected to the signal of the motor 201 that drives the push plate 205 on the same side to move.

[0053] A push plate 205 is arranged in the gap between the transmitter and the receiver of the first photoelectric sensor 210 and the second photoelectric sensor 211. The structure composed of the first photoelectric sensor 210, the second photoelectric sensor 211 and the push plate 205 is distributed in two groups in front and behind the supporting main board 101, and in each group, the difference between the length of the push plate 205 and the horizontal distance between the first photoelectric sensor 210 and the second photoelectric sensor 211 remains unchanged.

[0054] In the present invention, avoidance grooves 208 are respectively provided on the upper and lower surfaces of the frame push member 209, so that the push plate 205 will not interfere with the driven roller 506 during the reciprocating sliding process. At the same time, the avoidance grooves 208 also have the function of positioning the push plate 205, thereby preventing the push plate 205 from failing in the clamping connection with the roller groove 507 provided on the driven roller 506.

[0055] In addition, the first photoelectric sensor 210 and the second photoelectric sensor 211 are used to limit the reciprocating motion of the push plate 205. Figure 5 As shown, when the push plate 205 moves to the left until the right end of the push plate 205 no longer blocks the transmitter of the first photoelectric sensor 210, the receiver of the first photoelectric sensor 210 receives the light signal from the transmitter, and feedback is that the push plate 205 has moved to the left to the extreme position, and at this time, the group of motors 201 stops continuing to drive the push plate 205 to move to the left; conversely, when the push plate 205 moves to the right until the left end of the push plate 205 no longer blocks the transmitter of the second photoelectric sensor 211, the receiver of the second photoelectric sensor 211 receives the light signal from the transmitter, and feedback is that the push plate 205 has moved to the right to the extreme position, and at this time, the group of motors 201 stops continuing to drive the push plate 205 to move to the right.

[0056] In addition, due to the limitation of the installation space of the first photoelectric sensor 210 and the second photoelectric sensor 211, the installation positions of the first photoelectric sensor 210 and the second photoelectric sensor 211 distributed on the front and rear sides are not the same. Therefore, in order to ensure that the pushing stroke of the single and double frames is consistent, the lengths of the two push plates 205 on both sides of the supporting main board 101 are different, and the length of the push plate 205 on the same side and the difference in the horizontal distance between the first photoelectric sensor 210 and the second photoelectric sensor 211 remain unchanged, and the difference is the stroke of the push plate 205.

[0057] For further explanation of the present invention, see Figure 6 , Figure 7 The floating assembly 300 includes a first core shaft 301, a swing arm 302, a second core shaft 303, a floating roller 304, a mounting base 305, and a spring 306. The middle part of the first core shaft 301 is fixedly mounted on the supporting main board 101. The first core shaft 301 is hinged to the first end of the swing arm 302. The second end of the swing arm 302 is fixedly mounted with the second core shaft 303. The floating roller 304 is rotatably mounted on the middle part of the second core shaft 303. The outer circumferential surface of the floating roller 304 overlaps with the lower surface of the push plate 205.

[0058] The lower surface of the swing arm 302 is fixedly connected to the first end of the spring 306 , and the second end of the spring 306 is fixed to the upper surface of the mounting base 305 . The mounting base 305 is fixedly mounted on the bottom of the supporting mainboard 101 .

[0059] The structure consisting of the swing arm 302 , the second core shaft 303 , the floating roller 304 , and the spring 306 is symmetrically distributed in two groups in the front and rear directions with respect to the center plane of the supporting main board 101 .

[0060] Among them, when the outer circumferential surface of the floating roller 304 overlaps with the lower surface of the push plate 205, the floating roller 304 and the driven roller 506 located above the push plate 205 are aligned up and down. This structure is to ensure that the floating roller 304 always has an upward thrust on the push plate 205, and works together with the driven roller 506 above the push plate 205 to clamp the push plate 205, so that the horizontal height of the push plate 205 remains stable, that is, the push plate 205 is kept in a horizontal state.

[0061] Among them, the spring 306 is always in a compressed state. Under the elastic force of the spring 306, through the hinge relationship of the first end of the swing arm 302, an upward thrust is exerted on the floating roller 304 installed at the second end of the swing arm 302, thereby ensuring that the outer surface of the floating roller 304 is always overlapped with the lower surface of the push plate 205.

[0062] In this embodiment, the push plate 205 is placed at an upper limit by a driven roller 506 located above the push plate 205, and is placed at a lower limit by a floating roller 304 located below the push plate 205, so that the push plate 205 always remains stable during the movement. On the one hand, the travel control of the push plate 205 pushing frame is more precise, and on the other hand, the movement friction is reduced, thereby avoiding jamming of the push plate 205 during the pushing process.

[0063] As another embodiment of the present invention, see Figure 8 The driven roller wheel group 500 also includes a fourth core shaft 501, a second retaining ring 502, a fastening nut 503, and a second bearing 504. The middle part of the fourth core shaft 501 is coaxially installed in a circular through hole opened in the supporting main board 101. The fourth core shaft 501 is coaxially fixed with the second retaining ring 502. The second retaining ring 502 overlaps with the first side surface of the supporting main board 101, and the second side surface of the supporting main board 101 overlaps with the fastening nut 503. The fastening nut 503 is threadedly connected to the fourth core shaft 501.

[0064] A driven roller 506 is mounted on the first end of the fourth core shaft 501 through a second bearing 504 . The structure composed of the second bearing 504 and the driven roller 506 is symmetrically distributed in two groups in the front and rear with respect to the center plane of the supporting main board 101 .

[0065] The second bearing 504 and the driven roller 506 disposed on both sides of the support main board 101 respectively drive the pushing mechanism 200 disposed on both sides of the support main board 101, thereby realizing a single-frame or double-frame pushing device.

[0066] The above-mentioned structure of the present embodiment, on the one hand, realizes the installation and disassembly of the fourth core shaft 501 on the supporting main board 101 by tightening the threaded connection relationship between the nut 503 and the fourth core shaft 501, which is convenient and quick; on the other hand, the driven roller 506 installed by the second bearing 504 acts as a driven member to provide smaller resistance during the movement of the push plate 205, thereby reducing the wear on the push plate 205, effectively extending the service life of the push plate 205, and to a certain extent ensuring the accuracy of the push plate 205 in pushing the frame.

[0067] As another embodiment of the present invention, see Figure 1 , Fig. 9The active roller 406 is rotatably mounted on the supporting main board 101 through the active roller group 400. The active roller group 400 includes a third core shaft 401, a first retaining ring 402, a fixed retaining spring 403, a first bearing 404, and an annular ring 407. The middle part of the third core shaft 401 is coaxially mounted in a circular through hole opened in the supporting main board 101. The third core shaft 401 is coaxially fixed with the first retaining ring 402. The first retaining ring 402 overlaps with the first side surface of the supporting main board 101, and the second side surface of the supporting main board 101 overlaps with the fixed retaining spring 403. The fixed retaining spring 403 is clamped in an annular groove opened on the outer surface of the third core shaft 401.

[0068] An active roller 406 is installed on the first end of the third core shaft 401 through a first bearing 404. The outer circumferential surface of the active roller 406 is provided with a plurality of grooves in an annular shape. An annular ring 407 is arranged in the groove. The structure composed of the first bearing 404, the active roller 406 and the annular ring 407 is symmetrically distributed in two groups in the front and rear with respect to the center plane of the supporting main board 101.

[0069] Among them, the material of the annular ring 407 can be a material with a large friction coefficient such as rubber or latex, so as to ensure that during the rotation of the active roller 406, the friction between the active roller 406 and the push plate 205 can be increased through the annular ring 407, so that the reciprocating sliding stroke accuracy of the push plate 205 is higher.

[0070] In this embodiment, the mutual cooperation between the first retaining ring 402 and the fixed retaining spring 403 facilitates the installation and disassembly of the third core shaft 401. In addition, the active roller 406 is installed on the third core shaft 401 through the first bearing 404, which can reduce the rolling friction of the active roller 406, thereby making the driving of the active roller 406 by the motor 201 more energy-efficient and efficient; the structure composed of the first bearing 404, the active roller 406, and the annular ring 407 symmetrically distributed on both sides of the supporting main board 101 is used to drive the pushing mechanism 200 distributed on both sides of the supporting main board 101 respectively, thereby realizing the pushing of a single frame or a double frame.

[0071] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention.
