Description

Technical Field

[0001] The present invention relates to the technical field of touch screen production, and in particular to a connection line welding device and a welding method for touch screen production. Background Art

[0002] The connecting circuit board is an indispensable part in the production process of the touch screen. When making the connecting circuit board, it is necessary to weld the surface of the connecting circuit board. In the prior art, the way to weld the connecting circuit board is usually: people hold the solder wire in their left hand and the welding head in their right hand. After the end of the solder wire is close to the welding point, the welding head is used to approach the welding point. The welding head can melt the solder wire and weld it on the connecting circuit board. If it is necessary to weld a welding component to the connecting circuit board, people need to put down the solder wire with their left hand, and use tweezers to clamp the component and approach the welding point, and then use the welding head to melt the welding point so that the component is welded at the welding point.

DETAILED DESCRIPTION

[0033] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0034] Example 1: Refer to the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 A connection line welding device for touch screen production includes a welding table 1 as a bearing body, a control body 101 is slidably connected to the welding table 1, the control body 101 is connected to an electric welding gun 104 and a shell 2 through a line 102, a solder wire 203 longitudinally penetrates the shell 2, and the control body 101 moves left and right under the drive of a driving device. The driving device is a prior art and is not elaborated in this embodiment.

[0035] During the welding process of the present invention, the driving device can drive the control body 101 to move left and right. The position of the control body 101 can be adjusted according to people's usage habits, so as to adjust the positions of the welding gun 104 and the shell 2. People hold the welding gun 104 in their right hand and the solder wire 203 in their left hand, and use them in coordination with each other to weld the connected circuit board.

[0036] The solder wire 203 is selected to have a relatively low hardness so that it can melt quickly when heated and flow to the part that needs to be welded. The solder wire 203 is wound on a storage member, such as the take-up drum 202 in the present embodiment. The take-up drum 202 is installed on a fixed member, such as the circular cavity above the shell 2 in the present embodiment. The solder wire 203 is wound on the take-up drum 202. The take-up drum 202 is used to store the solder wire 203. A self-locking device is provided on the take-up drum 202. The self-locking device can realize that the take-up drum 202 can only rotate counterclockwise in one direction but cannot rotate clockwise. The self-locking device is a prior art and is not elaborated in the present embodiment. If the solder wire 203 is needed, the lower end of the solder wire 203 can be manually pulled downward, but the self-locking device cannot make the solder wire 203 re-reeled onto the take-up drum 202.

[0037] Reference Figure 1 The welding gun 104 and the shell 2 are respectively connected by a holder 103 connected to the control body 101, and a clamping ring with a diameter larger than the holder 103 is respectively arranged above the welding gun 104 and the shell 2. In the non-welding state, the welding gun 104 and the shell 2 can be passed through the holder 103 from top to bottom, so that the clamping ring is placed above the holder 103, and the clamping ring is supported by the holder 103 to put the welding gun 104 and the shell 2 in place.

[0038] Reference Figure 5-6 A finger piece 204 is slidably connected to the shell 2, and a side wall of the finger piece 204 is fixedly connected to a moving block 2015, and the moving block 2015 and the shell 2 are slidably connected.

[0039] In the prior art, people usually hold the solder wire in their left hand and the welding head in their right hand. After the end of the solder wire is close to the welding point, the welding head is used to approach the welding point, and the welding head can melt the solder wire and weld it on the connecting circuit board. If it is necessary to weld a welding component to the connecting circuit board, people need to put down the solder wire with their left hand, and use tweezers to clamp the component and bring it close to the welding point, and then use the welding head to melt the welding point so that the component is welded at the welding point. In the present invention, during the welding process, people hold the housing 2. It should be noted that when holding it, refer to the attached drawing. Figure 2 , the thumb can be placed on the pressing groove 205 opened in the middle of the finger piece 204, and the lower end of the solder wire 203 is exposed from the shell 2, and the solder wire 203 and the electric welding gun 104 can be used for welding. If the solder wire and tweezers need to be switched, there is no need to manually change them. People pinch the finger piece 204 with their thumb and slide it up. The finger piece 204 drives the moving block 2015 to move up and pulls the solder wire 203 up into the shell 2 through the clamping assembly.

[0040] Reference Figure 4The lifting body 2011 is slidably connected to the shell body 2, and both ends of the lifting body 2011 extend out of the two ends of the shell body 2. Both sides of the lifting body 2011 are slidably connected with a clamp 2012, and the clamp 2015 is a tweezers in the prior art. In the initial state, the clamp 2015 is located inside the shell body 2. When the finger piece 204 moves up to pull the solder wire 203 up and into the shell body 2, the lifting body 2011 will move down through the transmission component, thereby driving the clamp 2012 to move down and extend out of the shell body 2, so that the solder wire 203 and the clamp 2012 can be automatically switched, and the connection line welding work is more convenient. When the solder wire 203 needs to be extended for use, the finger piece 204 can be pinched and moved down by hand, and the solder wire 203 can be pulled down and out of the shell body 2 through the clamping component, and the clamp 2015 will be automatically collected into the shell body 2, which can prevent the clamp 2015 from being exposed outside all the time and affecting the use of the solder wire 203.

[0041] However, please refer to the attached Figure 5 , 7 8. The clamping assembly includes a hollow tube 21 longitudinally installed in the middle of the housing 2, the solder wire 203 passes through the hollow tube 21, and the hollow tube 21 can guide the direction of the solder wire 203. The clamp body 1 2016 and the clamp body 2 2017 are respectively slidably connected to the hollow tube 21, and the solder wire 203 is placed between the clamp body 1 2016 and the clamp body 2 2017. The clamp body 1 2016 and the clamp body 2 2017 are close to each other on one side and are semi-circular. The diameter of the two is smaller than the solder wire 203. The diameter is circular, and the clamp body 1 2016 is a stationary body relative to the clamp body 2 2017, while the clamp body 2 2017 is a movable body. After the clamp body 2 2017 moves to the left, it cooperates with the clamp body 1 2016 to form a relative extrusion force, and the outer end surface of the solder wire 203 is compressed by the extrusion force to achieve the purpose of clamping. The side of the clamp body 1 2016 and the clamp body 2 2017 that contacts the solder wire 203 can be a rough surface, a rubber surface, etc., in order to enhance the function of clamping the solder wire 203.

[0042] In addition, refer to the attached Figure 7The second clamp body 2017 is laterally inserted into the moving block 2015, and the second clamp body 2017 is slidably connected to the moving block 2015. The first clamp body 2016 is fixedly connected to symmetrical guide columns 2019, and the guide columns 2019 are respectively slidably connected to the second clamp body 2017. The guide columns 2019 can keep the first clamp body 2016 and the second clamp body 2017 in a horizontal state, so as to avoid the misalignment of the first clamp body 2016 and the second clamp body 2017 and affect the clamping of the solder wire 20 3, a column 2018 is welded on one side of the clamp body 2017 away from the clamp body 1 2016, and the column 2018 cooperates with the guide plate 2014 to apply a driving force to the clamp body 2017, and the guide plate 2014 is connected to a fixed component, which may be the wall of the hollow tube 21 in this embodiment. A vertical straight rail and an inclined rail connected to the end of the vertical straight rail are arranged on the guide plate 2014, and the inclined rail is integrated with the vertical straight rail, and the column 2018 cooperates with the vertical straight rail and the inclined rail respectively.

[0043] A return spring 2013 is welded on the clamp body 1 2016 and the clamp body 2 2017 respectively. The ends of the return spring 2013 that are close to each other are fixed on the lifting body 2011. The function of the return spring 2013 is to drive the clamp 2012 to recover after it is released after the clamp 2012 is close to the clamping element.

[0044] To put the solder wire 203 into the housing 2, the moving block 2015 is moved upward by pushing the finger 204 as described above, and the moving block 2015 moves upward to drive the second clamp 2017 and the column 2018 to move upward. Initially, the column 2018 is located at the inclined rail position, and the column 2018 moves upward to slide along the inclined rail to the upper left to the vertical straight rail position. The column 218 drives the second clamp 2017 to move left at the same time, and the second clamp 2017 and the first clamp 2016, which were originally far away from each other, will gradually move closer, and the second clamp 2017 and the first clamp 2016 will clamp the solder wire 203 together;

[0045] Then, the moving block 2015 continues to drive the second clamp 2017 and the column 2018 to move upward, and the column 2018 moves upward along the vertical straight track, while the second clamp 2017 and the first clamp 2016 keep clamping the solder wire 203, and the part of the solder wire 203 exposed from the shell 2 can be put into the shell 2;

[0046] When the solder wire 203 is to be exposed from the shell 2, the finger 204 can be pushed downward in the opposite direction, and the solder wire 203 can be pulled down and reset by means of the moving block 2015, the second clamp 2017 and the column 2018. Then, when the column 2018 moves from the vertical straight track to the inclined track, the column 2018 can drive the second clamp 2017 to move right to automatically loosen the solder wire 203, and the solder wire 203 is automatically exposed from the shell 2.

[0047] In the prior art, it may be selected that after the second clamp 217 and the first clamp 216 clamp the solder wire 203 upward, when the solder wire 203 is exposed from the housing 2, the second clamp 217 or the first clamp 216 is triggered to move away from each other to release the solder wire 203, and the folded part of the solder wire 203 sags down due to gravity to expose the housing 2. The present invention takes into account that when the solder wire 203 is pulled upward from below, the upper end of the solder wire 203 is fixed to the upper end of the housing 2, and the lower end of the solder wire 203 is unilaterally moved upward. When being pulled, the section of solder wire 203 that reaches the upper fixed position below the solder wire 203 will bend and deform. If the solder wire 203 is directly loosened, the solder wire 203 cannot be quickly restored after being bent and deformed, and the lower end of the solder wire 203 cannot automatically extend out of the shell 2. Therefore, the present invention adopts the method of clamping the solder wire 203 with the second clamp 2017 and the first clamp 2016 to clamp the solder wire 203 and then pull it down. Compared with the prior art, the present invention can better perform relevant actions according to the characteristics of the solder wire 203.

[0048] The above operation only requires people to pinch the finger piece 204 with their thumb and push it up, so that the solder wire 203 can be automatically retracted and the clamp 2012 can be exposed outside the shell 2. Conversely, people can pinch the finger piece 204 with their thumb and move it down, so that the solder wire 203 can be automatically exposed and the clamp 2012 can be retracted into the shell 2. This overcomes the problem in the prior art that people need to use their left hand to alternately replace the solder wire 203 and the tweezers, and the use is more portable.

[0049] Furthermore, a magnet block 2020 is arranged at the top position of the track where the moving block 2015 slides. The moving block 2015 is made of iron and has a high-strength magnet. The magnet block 2020 is adsorbed and cooperated with the moving block 2015 through magnetism. The high-strength magnetism can make the moving block 2015 stable at the top, prompting the second clamp 2017 and the first clamp 2016 to keep the solder wire 203 in the state of moving up, thereby preventing the solder wire 203 from accidentally moving out when people are using the clamp 2012, thereby affecting the use of the clamp 2012.

[0050] It also includes a rack 206, which is welded to the bottom of the finger 204, the rack 206 meshing with the gear 208, the gear 208 meshing with the rack 207, and a connecting rod 2010 fixedly connected between one end of the lifting body 2011 and the rack 207; the rack 206, the gear 208, the rack 207 and the connecting rod 2010 components serve as a transmission component between the finger 204 and the lifting body 2011, and when the finger 204 moves up, the lifting body 2011 can be moved down through the cooperation between the rack 206, the gear 208, the rack 207 and the connecting rod 2010; conversely, when the finger 204 moves down, the lifting body 2011 is driven to move up through the rack 206, the gear 208 and the rack 207.

[0051] Reference Figure 3 , the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010 are all exposed outside the housing 2, and people usually hold the housing 2 by hand when using it. If people mishandle the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010, it will not only scratch the hands, but also affect the operation of the switching work. Therefore, the present invention also provides a set of components near the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010 on the housing 2. The casing 201 at the position of the rack 207 and the connecting rod 2010 surrounds the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010, and can shield the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010 components. Therefore, even if people are close to the positions of the rack 1 206, the gear 208, the rack 207 and the connecting rod 2010, they can only touch the casing 201, thereby reducing the danger of use.

[0052] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 9-10 In the initial state, the lifting body 2011 and the chuck 2012 are located inside the shell 2. Normally, the lifting body 2011 and the chuck 2012 have a certain weight, and the rack 1 206, the gear 208 and the rack 2 207 remain in a mutually meshing state. The lifting body 2011 and the chuck 2012 may move downward due to the load-bearing, and the solder wire 203 may be retracted into the shell 2, which will affect people's use. Therefore, the present invention also includes a guide block 303 connected to the inside of the shell 2, and a card member 302 is slidably connected to the guide block 303. A card slot is opened in the middle of the lifting body 2011, and a protrusion is arranged at the lower end of the card member 302. Through the card slot engagement with the protrusion, an inclined surface is arranged on the side of the card member 302 away from the card slot. A pressing block 3 is arranged on the pressing groove 205, and the side of the pressing block 3 is connected to the push rod 301. The push rod 301 and the pressing groove 205 are slidably connected, and the push rod 301 and the inclined surface are squeezed and engaged.

[0053] Before people prepare to move the finger piece 204 upward, people need to press the pressure block 3 first. Otherwise, even if people move the finger piece 204 upward, the lower end protrusion of the clamping piece 302 is stuck in the clamping groove, so that the lifting body 2011 is restricted and cannot move downward, and the finger piece 204 cannot move upward either, resulting in locking. The advantage is that it can avoid the situation where the clamping head 2012 moves downward and the solder wire 203 is collected into the shell 2 due to the weight of the lifting body 2011 and the clamping head 2012. Therefore, before people prepare to move the finger piece 204 upward, people need to press the pressure block 3 first. The movement of the pressure block 3 drives the push rod 301 to move along the inclined surface, and the push rod 301 pushes the clamping piece 302 forward through the inclined surface. The clamping piece 302 moves forward and automatically disengages from the clamping groove, thereby releasing the lock on the lifting body 2011, and then the finger piece 204 can be moved upward to realize its function.

[0054] As mentioned above, after the clamp 302 is pushed out of the slot and the lifting body 2011 drives the slot to move downward, the purpose of switching the clamp 2012 downward is achieved. If the lifting body 2011 needs to be moved upward and reset, no component is provided to make the clamp 302 re-enter the slot to achieve the purpose of locking the lifting body 2011. Therefore, a component for resetting the clamp 302 is provided. The present embodiment has the following solutions:

[0055] Reference Fig.13 A moving link 501 is slidably connected in the shell 2, and a plate 5 is welded to the rear of the moving link 501. The left part of the plate 5 is squeezed and matched with the column 2018. A wedge block 502 is slidably connected to the front part of the moving link 501. The wedge block 502 and the clamping piece 302 are squeezed and matched. A buffer spring 503 is connected between the moving link 501 and the wedge block 502. When the push rod 301 moves left and pushes the clamping piece 302 forward, the clamping piece 302 will push the wedge block 502 to move left due to the wedge surface of the wedge block 502. At this time, since the column 2018 always keeps the left side of the plate 5 against the plate 5, the plate 5 and the moving link 501 cannot move with the wedge block 502, so the buffer spring 503 can only shrink.

[0056] When the finger 204 drives the moving block 2015, the second clamp 2017, and the column 2018 to move up a certain distance, the column 2018 will move leftward due to the inclined rail. The leftward movement of the column 2018 means that it will slowly separate from the plate 5. After the column 2018 and the plate 5 separate, the plate 5 loses the force to be resisted, and the longitudinal length of the inclined surface set at the upper end of the clamp 302 is much larger than the length of the inclined rail. In this way, after the column 2018 and the plate 5 separate, the push rod 301 is still in a state of squeezing the inclined surface of the clamp 302, so that the clamp 302 is always kept in a state of being pushed forward. In this way, the clamp 302 also keeps in a state of resisting the wedge block 502, and the restoring force of the buffer spring 503 will push the moving connecting rod 501 and the plate 5 to the left.

[0057] Afterwards, during the downward movement of the finger piece 204 to drive the moving block 2015, the clamp body 2017, and the column 2018 to move downward and reset, people release the pressing block 3 with their fingers in advance to prevent the push rod 301 from pressing the clamp 302 after it is reset and affecting the reset of the clamp 302. After the column 2018 re-enters the inclined track, it will automatically move right to push the plate 5 to move right. The right movement of the plate 5 drives the moving connecting rod 501, the buffer spring 503, and the wedge block 502 to move right. The right movement of the wedge block 502 will push the protrusion under the clamp 302 back into the slot through the wedge surface to lock the lifting body 2011.

[0058] When using the chuck 2012 to clamp the element, the chuck 2012 needs to be pushed to the side closer to each other. In this embodiment, it also includes a push block 4 slidably connected to the shell 2. The push block 4 is located on the right, and people's index finger can be placed on the push block 4. The push block 4 is provided with a connecting frame 402 near the inside of the shell 2, and a V-shaped rod 403 is connected below the connecting frame 402. Contact columns 404 are welded on the upper ends of the chucks 2012, and the contact columns 404 and the V-shaped rods 403 are squeezed together.

[0059] After the lifting body 2011 descends and drives the chuck 2012 and the contact column 404 to descend, the contact column 404 just contacts with the V-shaped rod 403, and people can push the push block 4 upward with their index finger, and the push block 4 drives the V-shaped rod 403 to move upward through the connecting frame 402, and the V-shaped rod 403 can push the contact column 404 to the side close to each other and then drive the chuck 2012 to the side close to each other, so that the chuck 2012 can be used to clamp the components conveniently, and the concave shape in the middle of the push block 4 fits the user's fingers, which makes it convenient to push the push block 4, and then the push block 4 can be released, and the reset spring 2013 can automatically drive the chuck 2012 and the contact column 404 to move away from each other and reset, thereby automatically driving the connecting frame 402 and the push block 4 to move down and reset through the V-shaped rod 403.

[0060] In addition, since the push block 4 and the shell 2 are slidably connected, there must be a slide groove between them, which will expose the interior of the shell 2 and allow dust to easily enter. Therefore, a shielding body 401 is provided, which is disposed on the push block 4 and can cover the slide groove.

[0061] A welding method for a connecting line welding device for touch screen production comprises the following steps:

[0062] S1: Fix the connection circuit board on the welding table 1, hold the housing 2 with the left hand to bring the lower end of the solder wire 203 close to the welding position, hold the welding gun 104 with the right hand, and cooperate with each other to weld;

[0063] S2: When it is necessary to clamp the component, the thumb first presses the pressing block 3, the pressing block 3 pushes the push rod 301, and the push rod 301 pushes the clamping member 302 to release the lifting body 2011;

[0064] S3: Then the pressing block 3 can be pushed upward, and the finger 204 is pushed upward, so that the clamp 2012 extends out of the housing 2 through the rack 1 206, the gear 208 and other components, and the solder wire 203 can be automatically collected into the housing 2 under the cooperation of the moving block 2015, the clamp 1 2016 and the clamp 2 2017 and other components;

[0065] S4: Afterwards, the index finger can move the push block 4 upward, and the push block 4 drives the connecting frame 402 and the V-shaped rod 403 to move upward.

[0066] This in turn drives the clamping head 2012 to move the clamping element.
