[0033] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] See also Figure 1-3 As shown, the embodiment of the present application provides a tinning mechanism, which includes a driving assembly 100, a swing assembly 200 and a tinning assembly 300; the swing assembly 200 is connected to the driving assembly 100, and the driving assembly 100 is used to drive the swing assembly 200 to swing back and forth around a preset axis 203; a first mounting structure 201 and a second mounting structure 202 are formed on the swing assembly 200, and the first mounting structure 201 and the second mounting structure 202 are respectively arranged on both sides of the preset axis 203; there are two tinning assemblies 300, each of which includes a transmission mechanism 310 and a tinning assembly 300. Tin structure 320, a transmission mechanism 310 is interlockedly configured between the first mounting structure and a tin point structure 320, and another transmission mechanism 310 is interlockedly configured between the second mounting structure and another tin point structure 320. Both tin point structures 320 respond to the movement of the corresponding transmission mechanism 310 to reciprocate along the preset direction Z, so that the two tin point structures 320 can reciprocate alternately, wherein the alternating reciprocating motion refers to that when one tin point structure 320 moves toward the swing component 200, the other tin point structure 320 moves in a direction away from the swing component 200.

[0035] Specifically, the driving component 100 may include a motor, which may be a servo motor to ensure rotation accuracy. The motor is a forward and reverse motor. The motor has a driving shaft that rotates around its own axis. The central axis of the driving shaft is the preset axis 203. The driving shaft is connected to the swinging component 200 to drive the swinging component 200 to rotate around the preset axis 203. The present tinning mechanism can drive two tinning structures 320 to move separately by setting a motor.

[0036] The swing assembly 200 may include a swing arm, which may be a rod-shaped structure or a plate-shaped structure, etc. The swing arm is extended in a direction perpendicular to the preset axis 203 to form two mounting portions on both sides of the preset axis 203, and the two mounting portions are respectively a first mounting structure 201 and a second mounting structure 202. Therefore, it can be understood that when the driving component drives the swing assembly 200 to swing, the first mounting structure 201 and the second mounting structure 202 reciprocate (or swing) around the preset axis 203, and the rotation direction of the first mounting structure 201 and the second mounting structure 202 can be clockwise or counterclockwise, and the swing angle can be between ±45°, that is, the swing assembly 200 can rotate 45° from a horizontal position in a clockwise direction around the preset axis 203, and can also rotate 45° from a horizontal position in a counterclockwise direction around the preset axis 203.

[0037] The two tinning components 300 are respectively connected to the first mounting structure 201 and the second mounting structure 202. The two tinning components 300 are used to respond to the movement of the swing component 200, and can make the two tinning structures 320 move along a preset direction Z to perform double tinning operations. In addition, the above-mentioned setting can also reverse the movement direction of the two tinning structures 320 to achieve the effect of enabling the two tinning structures 320 to perform tinning separately.

[0038] Specifically, the two tinning assemblies 300 are respectively located on the same side of the swing assembly 200, that is, the two tinning assemblies 300 are located on the same side of the line between the first mounting structure 201 and the second mounting structure 202, so that the two tinning structures 320 are located on the same side of the swing assembly 200, so that the two tinning structures 320 can be set close to each other.

[0039] The two tinning structures 320 each include a transmission mechanism 310 and a tinning structure 320, wherein the tinning structure 320 has a tinning needle for tinning operations, and the tinning needle can pick up solder paste; the transmission mechanism 310 can adopt a connecting rod mechanism, and the connecting rod mechanism can include at least two transmission arms hinged in sequence, and the transmission arms can adopt a rod-shaped structure or a plate-shaped structure, etc. The connecting rod mechanism is used to transmit motion, and the motion input ends of the two connecting rod mechanisms are respectively hinged to the first mounting structure 201 and the second mounting structure 202, and the motion output ends of the two connecting rod mechanisms can reciprocate along the preset direction Z. The motion output ends of the two connecting rod mechanisms are respectively connected to the two tinning structures 320 to drive the two tinning structures 320 to reciprocate in the preset direction Z respectively.

[0040] Among them, it can be understood that the first mounting structure 201 and the second mounting structure 202 are respectively located on both sides of the preset axis 203, and the two tinning components 300 are respectively connected to the first mounting structure 201 and the second mounting structure 202 through the transmission mechanism 310. The movement mode of the tinning component 300 is a linear reciprocating motion in the preset direction Z. Therefore, it can be known that the movement directions of the two tinning structures 320 are opposite. For example, when one tinning structure 320 slides in the direction away from the swing component 200, the other tinning structure 320 slides in the direction close to the swing component 200, so that the two tinning structures 320 can perform the actions of alternately tinning or alternately taking solder paste.

[0041] by Figure 1Taking the viewing angle direction in as an example, the working process of the tinning mechanism is as follows: the driving component 100 works to drive the swinging component 200 to swing around the preset axis 203. When the driving component 100 causes the swinging component 200 to rotate clockwise around the preset axis 203, the first mounting structure 201 located on the right side moves downward along the arc line, and the transmission mechanism 310 on the right side is linked, so that the transmission mechanism 310 drives the tinning structure 320 on the right side to move downward along the preset direction Z, and the tinning structure 320 moves downward to perform tinning or tinning. At the same time, the second mounting structure 202 located on the left side moves upward along the arc line, and the transmission mechanism 310 on the left side is linked, so that the transmission mechanism 310 drives the tinning structure 320 on the left side to move upward along the preset direction Z, and the tinning structure 320 moves upward to complete the tinning or tinning, and then separate from the workpiece to be processed or the tin plate; similarly, it can be understood that the process in which the driving component 100 causes the swinging component 200 to rotate counterclockwise around the preset axis 203 is opposite to the above-mentioned clockwise rotation process, which will not be repeated here.

[0042] In this embodiment, the tinning mechanism is provided with two tinning structures 320. The driving assembly 100 can simultaneously drive the two tinning structures 320 to perform tinning or tin removal respectively through the linkage of the swing assembly 200 and the transmission mechanism 310. The tinning mechanism can swing in the clockwise and counterclockwise directions at the tinning station through the swing assembly 200 to make the two tinning structures 320 perform tin removal respectively; after the tinning mechanism moves to the tinning station, it swings in the clockwise and counterclockwise directions again through the swing assembly 200 to make The two tinning structures 320 tin the workpieces to be processed respectively. For example, the two tinning structures 320 correspond to the N pole and P pole of the lamp bead on the chip respectively. When the swing component 200 rotates clockwise around the preset axis 203, one tinning structure 320 tins the N pole of the lamp bead. When the swing component 200 rotates counterclockwise around the preset axis 203, the other tinning structure 320 tins the P pole of the lamp bead, so as to complete the tinning operation of the two electrodes after one tinning operation, so as to reduce the number of round trips of the tinning mechanism and improve work efficiency.

[0043] In one embodiment, referring to Figure 1 and Figure 2 As shown, the preset direction Z is perpendicular to the direction of the preset axis 203 .

[0044] Specifically, the preset axis 203 is the swing axis of the swing component 200. When the driving component 100 has a rotating driving shaft, the preset axis 203 is the central axis of the driving shaft; the preset direction Z is the reciprocating movement direction of the tinning structure 320, that is, the motion trajectory of the tinning structure 320 is a straight line trajectory, then, the motion trajectory of the tinning structure 320 is perpendicular to the preset axis 203. When the transmission mechanism 310 is a planar connecting rod mechanism, it can be seen that the tinning structure 320 and the transmission mechanism 310 both move in a plane perpendicular to the preset axis 203, and the swing component 200 also swings in the plane. The swing plane of the swing component 200 is set as the working plane, then each transmission mechanism 310 and each tinning structure 320 moves in the working plane.

[0045] In this embodiment, the movement direction of the tinning structure 320 is perpendicular to the swing axis of the swing component 200. Then, the transmission mechanism 310 can adopt a planar connecting rod mechanism. The two tinning components 300 move in a working plane perpendicular to the preset axis 203. The two tinning components 300 are respectively arranged on both sides of the preset axis 203. The structure of the entire tinning mechanism is more compact and the operation is smoother.

[0046] In one embodiment, referring to Figure 1 As shown, the distance between the first mounting structure 201 and the preset axis 203 is equal to the distance between the second mounting structure 202 and the preset axis 203, and in the swing plane of the swing assembly 200, the projection point of the preset axis 203 is located on the perpendicular bisector of the line connecting the projection point of the first mounting structure 201 and the projection point of the second mounting structure 202.

[0047] Specifically, combined Figure 1 As shown, within the swing plane, the first mounting structure 201 and the second mounting structure 202 are symmetrically arranged on both sides of the preset axis 203. Therefore, it can be understood that the two tinning assemblies 300 are symmetrically located on both sides of the preset axis 203, so that the two tinning structures 320 can be arranged side by side so that they can both move back and forth along the preset direction Z.

[0048] In this embodiment, the first mounting structure 201 and the second mounting structure 202 are symmetrically arranged on both sides of the preset axis 203, so that the two tinning assemblies 300 can be arranged symmetrically on the left and right. When the swing angle of the swing assembly 200 is 0°, the two tinning assemblies 300 are in symmetrical positions, the output power of the driving assembly 100 reaches the minimum, and the two tinning assemblies 300 can alternately reciprocate under the drive of the driving assembly 100, and the operation stability of the entire tinning mechanism is better.

[0049] In one embodiment, the swing assembly 200 swings symmetrically in the counterclockwise direction and the clockwise direction around the preset axis 203, and the swing angle range of the swing assembly 200 is ±30°.

[0050] Specifically, refer to Figure 1 As shown, the position of the swing assembly 200 when it is in symmetrical balance is taken as the initial position, that is, the swing assembly 200 is in a horizontal position as the initial position, at which time, the two tinning structures 320 are symmetrically in the initial position; when the swing assembly 200 swings clockwise, it can swing clockwise by 30°, at which time, the tinning structure 320 on the right side descends to take tin or tinning, and at the same time, the tinning structure 320 on the left side is in an ascending state; then, the swing assembly 200 swings counterclockwise, first swinging back to the initial position, and the two tinning structures 320 are in the initial position. 20 are returned to the initial state, and then the swing assembly 200 continues to swing counterclockwise by 30°. At this time, the tinning structure 320 on the right side continues to rise from the initial position, and at the same time, the tinning structure 320 on the left side drops to a position below the initial position, and the tinning structure 320 on the left side performs the tinning or tin removal action; then, the swing assembly 200 can rotate clockwise and return to the equilibrium state of the initial position, and the tinning work of the two electrodes or the tin removal work of the two tinning structures 320 can be completed at one station to improve work efficiency.

[0051] In this embodiment, the swing angle of the swing component 200 determines the linear movement distance of the tinning structure 320. Therefore, the swing angle of the swing component 200 can be designed according to the up and down movement distance required by the tinning structure 320; making the swing component 200 swing symmetrically is conducive to improving the stability of the tinning mechanism during operation.

[0052] In one embodiment, referring to Figure 1 and Figure 2 and Figure 3 As shown, the tinning mechanism also includes a mounting seat 400; each transmission mechanism 310 includes a connecting rod mechanism, the input end of the connecting rod mechanism is rotationally connected to the swing assembly 200, the output end of the connecting rod mechanism is slidingly connected to the mounting seat 400, the output end of the connecting rod mechanism slides along a preset direction Z relative to the mounting seat 400, and the tinning structure 320 is connected to the output end of the connecting rod mechanism.

[0053] Specifically, the mounting seat 400 is a supporting component, and the mounting seat 400 may adopt a frame structure, a shell structure or a solid structure, etc. The driving component 100 , the swing component 200 , and the tinning component 300 may all be installed on the mounting seat 400 .

[0054] The connecting rod mechanism can adopt a planar connecting rod mechanism, which moves within the above-mentioned working plane. The connecting rod mechanism can adopt a transmission arm including multiple sequentially hinged transmission arms. The transmission arm located at the input end is connected to the swing assembly 200, and the transmission arm located at the output end is connected to the tinning structure 320. The transmission arm located at the output end can be slidably connected to the mounting seat 400 along the preset direction Z, so the tinning structure 320 is fixedly connected to the transmission arm to realize reciprocating movement along the preset direction Z.

[0055] The two tinning components 300 can be symmetrically arranged on both sides of the preset axis 203, and the two tinning structures 320 can be symmetrically arranged side by side on both sides of the preset axis 203. The two tinning components 300 can move in opposite directions up and down side by side. The connecting rod mechanism has the characteristics of high feedback and high control accuracy, ensuring the repeatable positioning accuracy of the tinning structure 320, thereby ensuring the uniformity of solder paste dotting and precise control of the tinning amount.

[0056] For example, combined with Figure 4 and Figure 5 As shown, each connecting rod mechanism includes a first transmission arm 311 and a second transmission arm 312, one end of the first transmission arm 311 is rotatably connected to the swing assembly 200, the other end of the first transmission arm 311 is rotatably connected to one end of the second transmission arm 312, the other end of the second transmission arm 312 is connected to the tinning structure 320, the second transmission arm 312 is slidably connected to the mounting base 400, and the second transmission arm 312 slides along a preset direction Z relative to the mounting base 400.

[0057] Specifically, the swing component 200 is plate-shaped, and the first mounting structure 201 and the second mounting structure 202 are respectively arranged on both sides of the preset axis 203. The first mounting structure 201 and the second mounting structure 202 are respectively mounting holes opened on the swing component 200. The two mounting holes are symmetrically arranged, and the two first transmission arms 311 are respectively connected to the two mounting holes through hinge shafts, thereby realizing the articulation of the two first transmission arms 311 and the swing component 200.

[0058] The first transmission arm 311 and the second transmission arm 312 can both adopt a rod-like structure or a plate-like structure. One end of each first transmission arm 311 away from the swing assembly 200 and one end of the second transmission arm 312 are hinged by a hinge shaft, and the other end of each second transmission arm 312 is slidably connected to the mounting base 400. Each second transmission arm 312 slides along a preset direction Z relative to the mounting base 400. The tinning structure 320 is connected to the second transmission arm 312. Therefore, it can be known that the tinning structure 320 can slide along the preset direction Z relative to the mounting base 400.

[0059] In this embodiment, each connecting rod mechanism is provided with two transmission arms, which is conducive to reducing the transmission connection relationship, reducing the complexity of the transmission mechanism 310, and reducing the distance between the drive assembly 100 and the tinning structure 320, which is conducive to shortening the transmission path, reducing the size of the tinning mechanism, and facilitating the miniaturization of the tinning mechanism; in addition, the first transmission arm 311 and the second transmission arm 312 both adopt a plate-like structure, which is conducive to improving the transmission stability of the entire transmission mechanism 310.

[0060] In one embodiment, referring to Figure 4 and Figure 5 As shown, the transmission mechanism 310 further includes a guide rail assembly 900 , which is connected between the second transmission arm 312 and the mounting seat 400 , so as to enable the second transmission arm 312 to slide along a preset direction Z relative to the mounting seat 400 .

[0061] A guide rail assembly 900 is provided between the second transmission arm 312 and the mounting seat 400 to enable the second transmission arm 312 to slide relative to the mounting seat 400, which is beneficial to improving the stability of the second transmission arm 312 during the sliding process; and, the guide rail assembly 900 can be prefabricated or purchased, which is beneficial to reducing the complexity of the entire tinning mechanism manufacturing process and improving the preparation efficiency of the mechanism.

[0062] Specifically, refer to Figure 4 and Figure 5 As shown, each guide rail assembly 900 includes a guide rail member 901 and a sliding seat 902. The guide rail member 901 is extended along a preset direction Z, and the guide rail member 901 is connected to the mounting seat 400; the sliding seat 902 is slidably connected to the guide rail member 901, and the sliding seat 902 is connected to the second transmission arm 312. The sliding seat 902 can be detachably connected to the second transmission arm 312 by a bolt assembly, and can also be directly welded and fixed to the second transmission arm 312.

[0063] In this embodiment, the two guide rail members 901 can be symmetrically arranged on both sides of the preset axis 203, and a sliding groove can be opened on the sliding seat 902. The guide rail member 901 can be slidably inserted in the sliding groove. The guide rail member 901 provides guidance for the movement of the second transmission arm 312, which is beneficial to improve the stability of the tinning structure 320 during the reciprocating movement.

[0064] In one embodiment, referring to Figure 4 and Figure 5 As shown, the first transmission arm 311 and the swing assembly 200 are rotationally connected via a first bearing structure 500 ; the first transmission arm 311 and the second transmission arm 312 are rotationally connected via a second bearing structure 600 .

[0065] Specifically, an articulated shaft can be installed on the first transmission arm 311, and the first mounting structure 201 and the second mounting structure 202 can both be mounting holes. The articulated shaft is inserted into the mounting hole, and the first bearing structure 500 is sleeved on the articulated shaft. The first bearing structure 500 is installed between the articulated shaft and the mounting hole. When the first transmission arm 311 rotates relative to the swing assembly 200, the first bearing structure 500 can reduce the friction between the articulated shaft and the mounting hole, thereby improving the rotation flexibility of the first transmission arm 311, which is beneficial to reducing power loss, reducing energy consumption, and reducing the noise when the first transmission arm 311 rotates relative to the swing assembly 200, thereby reducing the wear of the articulated shaft.

[0066] Similarly, the first transmission arm 311 and the second transmission arm 312 are connected by an articulated shaft. A hinge hole is provided at one end of the first transmission arm 311 away from the swing assembly 200. A hinge shaft is installed on the second transmission arm 312, and the hinge shaft is inserted into the hinge hole. The second bearing structure 600 is sleeved on the hinge shaft. The second bearing structure 600 is installed between the hinge shaft and the hinge hole. When the second transmission arm 312 rotates relative to the first transmission arm 311, the second bearing structure 600 can reduce the friction between the hinge shaft and the hinge hole, thereby improving the rotation flexibility of the second transmission arm 312, which is beneficial to reducing power loss, reducing energy consumption, and reducing the noise when the second transmission arm 312 rotates relative to the first transmission arm 311, thereby reducing the wear of the articulated shaft.

[0067] In one embodiment, referring to Figure 1 , Figure 4 and Figure 5 As shown, the tinning assembly 300 further includes an elastic structure 800 , which is connected between the tinning structure 320 and the mounting seat 400 , and the elastic structure 800 can be elastically deformed during the movement of the tinning structure 320 .

[0068] In this embodiment, since the first bearing structure 500 and the second bearing structure 600 have radial clearance, during the swinging of the first transmission arm 311 and the second transmission arm 312, vibration noise and friction noise are easily generated between the first bearing structure 500 and the mounting hole and between the second bearing structure 600 and the hinge hole, and may affect the smooth operation of the first transmission arm 311 and the second transmission arm 312. Therefore, an elastic structure 800 is arranged between the mounting seat 400 and the tinning structure 320. The elastic structure 800 can be a spring member. The elastic structure 800 can generate an elastic force between the mounting seat 400 and the tinning structure 320. The elastic force enables the tinning assembly 300 to always maintain a close contact state between the first bearing structure 500 and the mounting hole and between the second bearing structure 600 and the hinge hole during the movement, which is beneficial to reduce friction and vibration, reduce noise at the bearing position, improve the stability of the tinning assembly 300 during movement, and is beneficial to improve the operation accuracy of the tinning structure 320, thereby extending the service life of the entire tinning mechanism.

[0069] In one embodiment, referring to Figure 2-5 As shown, the tinning mechanism further includes a guide assembly 700 , which is disposed between the second transmission arm 312 and the mounting seat 400 to limit the second transmission arm 312 from moving along a preset direction Z.

[0070] Specifically, a guide groove is provided on the guide assembly 700, and the groove of the guide groove extends along the preset direction Z. Correspondingly, a protrusion structure is formed on the second transmission arm 312, and the protrusion structure is inserted into the guide groove and can slide along the preset direction Z in the guide groove.

[0071] Optionally, a protruding structure is formed on the guide assembly 700, and correspondingly, a guide groove is opened on the second transmission arm 312, the groove of the guide groove extends along the preset direction Z, the protruding structure is inserted into the guide groove, and can slide along the preset direction Z in the guide groove.

[0072] In this embodiment, the guide assembly 700 can be installed on the mounting base 400 and located on the side of the second transmission arm 312; the guide assembly 700 can further guide the movement direction of the second transmission arm 312 to ensure the movement accuracy of the second transmission arm 312, that is, to ensure the movement accuracy of the tinning structure 320, thereby improving the accuracy of tinning.

[0073] The embodiment of the present application also provides a rework device, which includes the tinning mechanism in the above embodiment. The rework device is used for re-tinning abnormal lamp beads on the chip. By setting the tinning mechanism in the above embodiment, the rework device can reduce the number of round trips of the tinning mechanism and improve work efficiency. Please refer to the above embodiment for details, which will not be repeated here.

These descriptions are only for explaining the principles of the present application and cannot be interpreted as limiting the scope of protection of the present application in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application, and other specific implementation methods of the present application that can be associated with the technicians in this field without creative work, should be included in the scope of protection of the present application.
