Description

Technical Field

[0001] The present invention relates to the field of patch technology, in particular to a patch device and a patch machine. Background Art

[0002] In optical communication products, patching is a common process. The diaphragm is generally made of glass, with a size of about 0.8mm×0.8mm and a thickness of about 0.5mm. During the mounting process, the diaphragm is sensitive to the pressure of the suction nozzle. Excessive mounting pressure will cause damage to the diaphragm or even cracking, resulting in product defects.

[0003] However, the random factors that cause pressure variations are not fully predictable, resulting in unreliable yield stability in current SMT systems. Since nozzle pressure cannot be monitored, random product inspections are required during the production process to infer equipment stability. This results in wasted labor costs for inspections and waste of materials for defective products, which can easily lead to defective products being shipped to the next process, hindering the ability to improve product quality control.

[0013] Optionally, a second slide is further connected to the mounting plate, and the second slide is located on the side of the mounting plate away from the first slide rail. The second slide includes a first base and a second base that slide relative to each other, and a rotating motor arranged on the first base. A trapezoidal groove is formed between the first base and the second base, and a wedge block is slidably connected in the trapezoidal groove. The wedge block is connected to the rotating motor through a screw, and the second base is connected to the mounting plate.

[0015] Compared to the prior art, the patch device and patch machine provided by the embodiments of the present invention have the following advantages: A mounting plate, a first linear drive assembly disposed on the mounting plate, and a vertically extending first slide rail are provided. A first slider is slidably connected to the first slide rail, and the first slider slides down the first slide rail under its own weight. As a result, the mounting bracket connected to the first slider, as well as the positioning block, guide bearings, and pressure sensor connected to the mounting bracket, all move synchronously with the first slider. Pairs of guide bearings are spaced apart on the positioning block, with the central axes of each pair of guide bearings forming a predetermined angle, forming guide slideways between each pair of guide bearings. The spaced guide bearings are then mated to ensure that the guide slideways are dispersed at both ends of the air duct, ensuring the straightness of the air duct during movement. During the initial stage of the first slider's sliding along the first slide rail, the air duct and mounting handle move synchronously with the first slider. A first magnetic member disposed on the positioning block and a second magnetic member connected to the air duct ensure reliable contact between the air duct and the guide bearings, ensuring a secure fit. After the suction nozzle on the air guide tube reaches the attachment surface, the suction nozzle is subjected to a reverse holding force. As the first slider continues to slide down due to gravity, the reverse holding force on the suction nozzle gradually increases, and the air guide tube moves up. In this way, the spring connected between the connecting rod and the mounting handle is stretched, causing the connecting rod to be stressed. Since the connecting rod is rotatably connected to the positioning block, and the distances between the two ends of the connecting rod and the rotation center are equal, the torques at both ends of the connecting rod are consistent. The force detected by the pressure sensor is the force exerted by the spring under the holding force, and the force exerted on the diaphragm during the attachment operation can be detected in real time. When the detected force reaches the preset pressure, the first drive assembly will act, driving the lifting arm to move upward, thereby lifting the first slider to the initial position through the limit frame, avoiding damage to the diaphragm caused by the continuous sliding of the first slider, and ensuring the desired attachment effect. The above method can reduce the waste of labor costs and the impact of human factors, which is conducive to improving the control ability of product quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0028] like Figures 1 to 3As shown, an embodiment of the present invention provides a patch device 100, comprising: a mounting plate 110, and a first linear drive assembly 120 and a vertically extending first slide rail 112 arranged on the mounting plate 110, a first slider 113 being slidably connected to the first slide rail 112, a mounting frame 114 being connected to the first slider 113, a positioning block 115 being connected to the mounting frame 114, a pair of guide bearings 1152 being arranged at intervals on the positioning block 115, the central axis of each pair of guide bearings 1152 being at a preset angle so that a guide slideway is formed between each pair of guide bearings 1152, an air guide tube 116 being arranged at the guide slideway, a suction nozzle 117 being arranged at the end of the air guide tube 116, a connecting rod 118 being rotatably connected to the positioning block 115, and a connecting rod 118 being rotatably connected to the mounting frame 114. A pressure sensor 119 is connected to one end of the connecting rod 118, and a mounting handle 130 is also connected to the air duct 116. The mounting handle 130 is abutted against the top of the positioning block 115, and the mounting handle 130 is connected to the other end of the connecting rod 118 through a spring 111. The two ends of the connecting rod 118 are at an equal distance from the rotation center. A first magnetic member 1154 is provided on the positioning block 115, and a second magnetic member (not shown in the figure) is connected to the air duct 116. The magnetic poles of the opposite sides of the first magnetic member 1154 and the second magnetic member are the same; the first slider 113 is also connected to a limit frame 140, and a first slot 142 is provided on the limit frame 140. The first linear drive assembly 120 is connected to a lifting arm 122 corresponding to the first slot 142, which is used to lift the limit frame 140 upward.

[0029] Specifically, by providing a first slide rail 112 on the mounting plate 110 and a first slider 113 slidably connected to the first slide rail 112, in actual use, the first slide rail 112 is arranged in a vertical direction, and the first slider 113 can slide along the first slide rail 112 under its own weight. At this time, the mounting bracket 114 connected to the first slider 113 and the positioning block 115 connected to the mounting bracket 114 can move synchronously with the first slider 113. By providing pairs of guide bearings 1152 spaced apart on the positioning block 115, with the central axes of each pair of guide bearings 1152 forming a predetermined angle, a guide slideway can be formed between each pair of guide bearings 1152. When each pair of guide bearings 1152 is spaced apart, they can stably cooperate with the air duct 116, ensuring that the air duct 116 moves linearly along the guide slideway. Through the mounting handle 130 connected to the air guide tube 116, and the mounting handle 130 abutting against the top of the positioning block 115, when the suction nozzle 117 at the end of the air guide tube 116 has not yet contacted the attachment surface, the air guide tube 116 moves synchronously with the positioning block 115. After the suction nozzle 117 contacts the attachment surface, the air guide tube 116 can move relative to the guide slide.

[0030] In addition, by rotating the connecting rod 118 connected to the positioning block 115, one end of the connecting rod 118 is connected to the pressure sensor 119 on the mounting bracket 114, and the other end of the connecting rod 118 is connected to the spring 111, and the spring 111 is connected between the connecting rod 118 and the mounting handle 130. After the suction nozzle 117 contacts the attachment surface, as the first slider 113 continues to slide downward under the action of gravity, the air guide tube 116 will slide upward under the action of the resistance force, thereby stretching the spring 111, thereby applying an elastic force to the connecting rod 118. Since the distances between the two ends of the connecting rod 118 and the rotation center are equal, that is, the lengths of the force arms on both sides of the rotation of the connecting rod 118 are equal, the force applied to the connecting rod 118 by the spring 111 is consistent with the force detected by the pressure sensor 119. Based on the interaction of forces, the adhesion force can be accurately detected. In addition, by adopting the form of attaching the patch by sliding down under its own weight, it is possible to prevent excessive pressure from causing damage to the nozzle 117 or the patch, and it is also possible to better control the maximum pressure value. The pressure value during attachment is controlled by cooperating with the first linear drive component 120 to ensure that the patch operation is carried out reliably. It should be noted that the end of the connecting rod 118 connected to the pressure sensor 119 can be considered to be stationary relative to the pressure sensor 119. Although the connecting rod 118 is rotationally connected to the positioning block 115, the connecting rod 118 does not rotate in actual application. This can ensure that the direction of the force applied to the connecting rod 118 by the spring 111 remains unchanged and does not cause distortion of the pressure detection by the pressure sensor 119.

[0031] When the pressure detected by the pressure sensor 119 reaches a preset pressure, the first linear drive assembly 120 activates, driving the lifting arm 122 upward. This, through the stop frame 140, lifts the first slider 113 to its initial position, preventing damage to the diaphragm caused by continued downward pressure from the first slider 113. It will be appreciated that the first slot 142 has a certain length so that the stop frame 140 is not affected by the lifting arm 122 as it moves downward following the first slider 113. During use, to prevent the airway 116 from detaching from the guide rail, a first magnetic member 1154 is provided on the positioning block 115. A second magnetic member is connected to the airway 116. The opposing magnetic poles of the first and second magnetic members are identical. This allows the magnetic attraction of the first and second magnetic members to hold the sidewalls of the airway 116 tightly against the guide bearing 1152, ensuring a secure connection.

[0032] The patch device 100 provided in the embodiment of the present application comprises a mounting plate 110, a first linear drive assembly 120 disposed on the mounting plate 110, and a vertically extending first slide rail 112. A first slider 113 is slidably connected to the first slide rail 112. Under its own weight, the first slider 113 slides down the first slide rail 112. Consequently, the mounting bracket 114 connected to the first slider 113, as well as the positioning block 115, guide bearings 1152, and pressure sensor 119 connected to the mounting bracket 114, all move synchronously with the first slider 113. Pairs of guide bearings 1152 are spaced apart on the positioning block 115, with the central axes of each pair of guide bearings 1152 forming a predetermined angle, thereby forming guide slideways between each pair of guide bearings 1152. The spaced apart guide bearings 1152 cooperate to ensure that the guide slideways are dispersed at both ends of the air guide tube 116, thereby ensuring the straightness of the air guide tube 116 during movement. In the initial stage of the first slider 113 sliding along the first slide rail 112, the air guide tube 116 and the mounting handle 130 move synchronously with the first slider 113. By means of the first magnetic member 1154 provided on the positioning block 115 and the second magnetic member connected to the air guide tube 116, the air guide tube 116 can be reliably supported against the guide bearing 1152, thereby ensuring the reliability of the fit. When the first slider 113 is pushed downward by the force of gravity, the suction nozzle 117 is subjected to a reverse resistance force, and the air guide tube 116 moves upward. In this way, the spring 111 connected between the connecting rod 118 and the mounting handle 130 is stretched, so that the connecting rod 118 is subjected to force. Since the connecting rod 118 is rotatably connected to the positioning block 115, and the distance between the two ends of the connecting rod 118 and the rotation center is equal, the torque at both ends of the connecting rod 118 is consistent. The force detected by the pressure sensor 119 is the force exerted by the resistance force on the spring 111, so that the force exerted on the diaphragm during the attachment operation can be detected in real time. When the detected force reaches the preset pressure, the first driving assembly will act to drive the lifting arm 122 to move upward, thereby lifting the first slider 113 to the initial position through the limit frame 140, avoiding the damage to the diaphragm caused by the continuous sliding of the first slider 113 and ensuring the required attachment effect. The above method can reduce the waste of labor costs and the impact of human factors, which is conducive to improving the control ability of product quality.

[0033] like Figure 2 As shown, multiple first slide rails 112 are arranged in parallel, and multiple telescopic cylinders 144 are arranged on the mounting plate 110. The multiple telescopic cylinders 144 are arranged one-to-one corresponding to the multiple first slide rails 112. The limit frame 140 is provided with a second slot 146 that can correspond to the telescopic cylinder 144, which is used to limit the sliding of the first slider 113 relative to the first slide rail 112 through the telescopic cylinder 144.

[0034] Specifically, by setting the first slide rail 112 in parallel to multiple, the matching components such as the suction nozzle 117 that cooperate with the first slide rail 112 are naturally also set to multiple groups, so that the patch device 100 can have multiple suction nozzles 117 to perform patch operations synchronously. In actual applications, it is possible to encounter a situation where only individual suction nozzles 117 need to work. At this time, through the telescopic cylinders 144 that correspond one-to-one to the first slide rail 112, the telescopic cylinders 144 corresponding to some of the suction nozzles 117 that do not need to work are actuated to extend the telescopic rod into the second slot 146. In this way, the first slider 113 cannot slide under the action of gravity. It is understandable that when the telescopic cylinder 144 is working, the first linear drive assembly 120 needs to cooperate to lift the second slot 146 to the height position corresponding to the telescopic cylinder 144. In addition, the length of the first slot 142 needs to ensure that after the limit frame 140 is limited by the telescopic cylinder 144, it will not interfere with the normal operation of the lifting arm 122.

[0035] like Figure 3 As shown, the first linear drive component 120 includes a first slide 124 sliding along the extension direction of the first slide rail 112, and a first motor 126 connected to the first slide 124. The lifting arm 122 is connected to the first slide 124. The lifting arm 122 is provided with a latching protrusion 1222 corresponding to the first slot hole 142. The latching protrusion 1222 can be movably held in the first slot hole 142. There are multiple latching protrusions 1222, and the multiple latching protrusions 1222 are arranged in a one-to-one correspondence with the multiple first slot holes 142.

[0036] Specifically, the first slide 124 and the first motor 126 are respectively connected to the mounting plate 110, and the sliding direction of the first slide 124 is consistent with the extension direction of the first slide rail 112. When the first motor 126 is in motion, it can drive the first slide 124 to move, thereby driving the lifting arm 122 connected to the first slide 124 to move up and down along the extension direction of the first slide rail 112. The locking protrusion 1222 provided on the lifting arm 122 facilitates the lifting arm 122 to cooperate with the first slot 142 through the locking protrusion 1222. When the patch operation is required, the lifting arm 122 is driven to move downward to avoid affecting the normal sliding of the first slider 113. When the patch operation is completed and the first slider 113 needs to be lifted, the lifting arm 122 is driven to move upward so that the locking protrusion 1222 abuts against the top of the first slot 142, and the first slider 113 is driven to move to the initial position before sliding down.

[0037] like Figure 4 and Figure 6As shown, the patch device 100 also includes a second linear drive component 150 connected to the mounting plate 110. The driving direction of the second linear drive component 150 is perpendicular to the driving direction of the first linear drive component 120. The second linear drive component 150 is connected to a pushing member 151 corresponding to the mounting handle 130. A plurality of push rods 1512 are connected to the pushing member 151. The plurality of push rods 1512 are arranged in a one-to-one correspondence with the plurality of mounting handles 130. The extension direction of the push rod 1512 is parallel to the extension direction of the first slide rail 112. The mounting handle 130 is provided with a rolling pulley 132 and a magnetic member 134 corresponding to the push rod 1512.

[0038] Specifically, while the air tube 116 moves vertically along the guide rail, it can also rotate relative to the guide rail. During actual operation, the angle of rotation of the air tube 116 can be adjusted to adjust the placement of the patch, thereby improving its usability. By providing a rolling pulley 132 and a magnetic member 134 corresponding to the push rod 1512 on the mounting handle 130, the magnetic member 134 ensures that the rolling pulley 132 is always in contact with the push rod 1512. Furthermore, the rolling friction between the rolling pulley 132 and the push rod 1512 negligible resistance to the vertical movement of the air tube 116. When the second linear drive assembly 150 drives the push member 151 to move laterally, the push rod 1512 can move synchronously with the push member 151, driving the mounting handle 130 to perform fine adjustments with the air tube 116 as the center, thereby ensuring the accuracy of the patch. It is understandable that the push rod 1512 needs to be able to be attracted to the magnetic component 134 . Therefore, the push rod 1512 can be made of a material that can be attracted to the magnetic component 134 , such as iron.

[0039] like Figure 4 and Figure 5 As shown, the second linear drive assembly 150 includes a vertical plate 152 connected to the mounting plate 110, and a second motor 153 arranged on the vertical plate 152, a cam 154 is connected to the second motor 153, and a second slide rail 155 is also provided on the vertical plate 152. The extension direction of the second slide rail 155 is perpendicular to the extension direction of the first slide rail 112, the pushing member 151 is slidably connected to the second slide rail 155, and a cam follower 156 is connected to the pushing member 151. An elastic member 157 is also connected between the pushing member 151 and the vertical plate 152 to make the cam follower 156 abut against the outer ring of the cam 154.

[0040] Specifically, by means of a second motor 153 provided on the vertical plate 152 and a cam 154 connected to the second motor 153, when the motor rotates, the cam 154 can be driven to rotate. When the cam 154 rotates, the cam follower 156 corresponding to the cam 154 always abuts against the edge of the cam 154 under the action of the elastic member 157. Under the joint action of the cam 154 and the elastic member 157, the cam follower 156 drives the pusher 151 to slide along the second slide rail 155. The elastic member 157 can be Figure 5 The tension spring 111 shown may also be a compression spring 111 or a torsion spring, which is mainly capable of ensuring that an elastic force close to the cam 154 is applied to the cam follower 156 .

[0041] like Figure 5 As shown, the cam 154 includes a rotating body 1542 , and a notch 1544 is provided on the rotating body 1542 . The edge of the notch 1544 and the outer circle of the rotating body 1542 form an involute curved surface.

[0042] Specifically, by forming an involute surface between the edge of the notch 1544 and the outer ring of the rotating body 1542, when the cam 154 rotates, the pushing member 151 can be driven to slide along the second slide rail 155. In addition, when the sliding position of the pushing member 151 is adjusted in the above-mentioned arrangement, the battery can continue to rotate forward to achieve the reciprocating movement of the pushing member 151, which is conducive to improving the convenience of control.

[0043] Please continue to refer to Figure 5 The pusher 151 is further provided with a sensing piece 158 , and the vertical plate 152 is provided with a sensor 159 corresponding to the sensing piece 158 .

[0044] Specifically, by providing a sensor 159 on the vertical plate 152 corresponding to the sensing sheet 158, it is convenient to confirm the initial position of the pusher 151, calibrate the pusher 151, and ensure the reliability of the pushing accuracy of the pusher 151. Among them, the sensor 159 can be a proximity switch or a Hall switch. When the sensor 159 is a Hall switch, a corresponding magnetic area can be provided on the sensing sheet 158.

[0045] like Figure 7 As shown, the mounting handle 130 includes a first connecting portion 135, a holding portion 136, an extending portion 137 and a second connecting portion 138 connected in sequence, the air guide tube 116 is connected to the first connecting portion 135, the holding portion 136 is abutted against the top of the positioning block 115, and the rolling pulley 132 and the magnetic component 134 are connected to the second connecting portion 138.

[0046] Specifically, the mounting handle 130 connects and positions the air duct 116 with the mounting handle 130 via the first connecting portion 135. The retaining portion 136 abuts against the top of the positioning block 115, ensuring the stability of the air duct 116 relative to the positioning block 115 in the initial state. Furthermore, the mounting handle 130 is extended a certain distance via the extending portion 137 to facilitate the mating of the second connecting portion 138 and the push rod 1512, ensuring a reliable connection between them.

[0047] like Figure 8 As shown, a second slide 160 is also connected to the mounting plate 110, and the second slide 160 is located on the side of the mounting plate 110 away from the first slide rail 112. The second slide 160 includes a first base 162 and a second base 164 that slide relative to each other, and a rotating motor 168 arranged on the first base 162. A trapezoidal groove is formed between the first base 162 and the second base 164. A wedge block 166 is slidably connected in the trapezoidal groove, and the wedge block 166 is connected to the rotating motor 168 through a screw. The second base 164 is connected to the mounting plate 110, and the sliding direction of the wedge block 166 is perpendicular to the sliding direction of the second base 164.

[0048] Specifically, the second base 164 is connected to the mounting plate 110, and the first base 162 can be connected to a fixed frame or a manipulator and other components in actual application to adapt to the current production environment. Through the cooperation of the first base 162 and the second base 164, the mounting plate 110 can be driven to move along the driving direction perpendicular to the first linear drive component 120 and the driving direction of the second linear drive component 150, thereby ensuring the convenience of adjusting the suction nozzle 117 in three-dimensional space. When it is necessary to adjust the position of the mounting plate 110 through the second slide 160, it is only necessary to rotate the screw by the rotary motor 168, and the screw drives the wedge block 166 to slide relative to the trapezoidal groove, thereby adjusting the opening between the first base 162 and the second base 164, and finally achieving the adjustment of the position of the mounting plate 110.
