DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0022] like Figures 1 to 8 As shown: A welding transmission device for wire bonding, comprising: a base 1, a heating platform 2, a lifting component 3 and a pushing component 4; The base 1 comprises a flat plate 11 and a vertical plate 12 which are perpendicular to each other. The flat plate 11 is provided with a first through slot 111. Two first guide rods 13 and a second guide rod 14 are arranged in parallel on both sides of the first through slot 111 on the base 1. The heating platform 2 passes through the first through slot 111, and the lifting assembly 3 is disposed at the bottom of the heating platform 2 for lifting the heating platform 2. The heating platform 2 is provided with a positioning hole 22 and an air suction hole 23 for positioning the chip; Two second through grooves 112 are provided on the flat plate 11 along the length direction of the first guide rod 13. Two pushing assemblies 4 are slidably provided on the vertical plate 12 along the length direction of the first guide rod 13, and include a first push rod 41 and a second push rod 42. The first push rod 41 and the second push rod 42 respectively pass through the two second through grooves 112 and reciprocate along the second through grooves 112. The first push rod 41 is used to push the chip to the heating platform 2, and the second push rod 42 is used to push the chip after wire bonding from the heating platform 2 to the next process.
[0023] Workflow: Such as Figure 1 As shown, the chip of the previous process enters the first guide rod 13 and the second guide rod 14 from the left end, and is pushed into the heating platform 2 area by the first push rod 41, and then the lifting component 3 drives the heating platform 2 to rise and position the chip. After the chip completes the wire bonding welding process, the lifting component 3 drives the heating platform 2 to descend, and the guide rod is pushed out by the second push rod 42 to enter the next process.
[0024] The lifting assembly 3 drives the heating platform 2 to move up and down, and can accurately adjust the distance between the chip and the heating platform 2, thereby achieving high-precision chip positioning and welding, which not only improves work efficiency, but also optimizes thermal management during the welding process, ensures that the chip is evenly heated, and improves welding quality.
[0025] By setting the first push rod 41 and the second push rod 42, the pushing component 4 can automatically push the chip from the first process to the heating platform 2, and automatically push the chip to the next process after the wire bonding is completed, thereby improving production efficiency, reducing the impact of manual intervention on the production process, and reducing the probability of human error; through automated pushing and lifting operations, the workflow of the production line is optimized, the transfer time of the chip between each process is shortened, and the overall production efficiency is improved, which is particularly suitable for mass production.
[0026] The device simplifies the complex mechanical and electrical control systems of traditional wire bonding transmission equipment, significantly reducing overall costs. The equipment maintenance and fault diagnosis are relatively simple, which helps to reduce the company's operating costs. It is particularly suitable for small and medium-sized enterprises to carry out mass production and enhances market competitiveness.
[0027] As a preferred embodiment of the above, Figure 2 , 3 As shown, each pushing assembly 4 further includes a first transmission wheel 43, a first synchronous belt 44, a pressure sensor 45 and a first driving member 46; The first driving member 46 is disposed on the vertical plate 12, the two first transmission wheels 43 are spaced apart along the length direction of the first guide rod 13, the first synchronous belt 44 is used to connect the two first transmission wheels 43, and the first driving member 46 drives the first transmission wheels 43 and the first synchronous belt 44 to rotate; The inner wall of the vertical plate 12 is parallel to the length direction of the first guide rod 13 and is provided with a first slide rail 121. The top of the pressure sensor 45 is provided with a first push rod 41 or a second push rod 42. The bottom of the pressure sensor 45 is provided on the first synchronous belt 44. The side wall is provided with a first slider 451. The first slider 451 slides along the first slide rail 121, so that the pressure sensor 45 reciprocates along the length direction of the first slide rail 121, thereby driving the first push rod 41 or the second push rod 42 to move along the length direction of the first guide rod 13. Specifically, the pressure sensor 45 is fixed on the first synchronous belt 44. 4, the sensor is driven to move by the movement of the first synchronous belt 44, and the first push rod 41 and the second push rod 42 are driven to move along the direction of the first guide rod 13 through this movement, so as to realize the function of pushing the chip; at the same time, the combined design of the first slide rail 121 and the first slider 451 improves the precision of the push rod movement, so that the first push rod 41 and the second push rod 42 can move more accurately along the length direction of the first guide rod 13, and this precise control can avoid the chip position deviation caused by inaccurate movement, thereby improving the working efficiency and welding precision of the overall system.
[0028] In this embodiment, when the applied pressure increases, the output end of the pressure sensor 45 will generate a corresponding signal, and the signal drives the first push rod 41 or the second push rod 42 to rise and engage with the fixed position on the chip. At the same time, the signal is transmitted to the first driving member 46 to drive the first push rod 41 or the second push rod 42 to the set position, and the pressure sensor 45 sends a contraction signal to make the first push rod 41 or the second push rod 42 descend, drive the first push rod 41 or the second push rod 42 to rise and disconnect from the fixed position on the chip, thereby ensuring reliable engagement and release of the chip. Specifically, the set position is the position where the first push rod 41 moves the chip to the heating platform 2, and the position where the second push rod 42 moves to the next process; through the precise linkage between the pressure sensor 45 and the push rod, the change can be sensed in time when the pressure is applied and the push rod can be accurately driven to rise or fall through the output signal. This precise control helps to ensure that the push rod will not deviate or malfunction during the engagement and disconnection process of the chip fixed position, and can effectively achieve precise loosening or engagement action, thereby ensuring reliable fixation and release of the chip.
[0029] Among them, Figure 4 As shown, the first push rod 41 and the second push rod 42 respectively include a first claw 411 and a second claw 412, the second claw 412 is arranged on one side of the first claw 411, and the first claw 411 and the second claw 412 are fixed by a locking piece 413, and the ends of the first claw 411 and the second claw 412 are jointly spliced into a dovetail groove 411d structure. Specifically, the locking piece 413 can be a bolt, which passes through the head of the first claw 411 and is locked with the threaded hole on the second claw 412. The locking piece 413 can also be other parts that adjust the distance by rotation. Due to the high precision requirement of chip clamping, the overall dovetail groove 411d structure is processed by wire cutting, and the precision of the dovetail groove 411d does not meet the requirement, so the dovetail groove 411d is made into a spliced structure, and the first claw 411 and the second claw 412 processed by a grinder are combined and spliced into a dovetail groove 411d, which is used to meet the high precision requirement of chip clamping and reduce the processing requirements.
[0030] As a preferred embodiment of the above, continue to refer to Figure 4The second claw 412 is provided with a first straight surface 412a, a second straight surface 412b, and a first inclined surface 412c connecting the first straight surface 412a and the second straight surface 412b on one side close to the first claw 411. The first claw 411 is correspondingly provided with a third straight surface 411a, a fourth straight surface 411b, and a second inclined surface 411c connecting the third straight surface 411a and the fourth straight surface 411b. The distance between the first claw 411 and the second claw 412 is controlled by adjusting the locking member 413, so as to control the size of the dovetail groove 411d, so as to realize the engagement and positioning of chips of different specifications, and increase the applicability of the first claw 411 and the second claw 412. In a production environment with diverse chip types and sizes, traditional fixed-size claws may not be able to adapt to all chip types, while the adjustable design provides greater flexibility for the system, can support the positioning and fixation of multiple chips, and avoids the problem of designing multiple sets of different claws for different chip types.
[0031] In this embodiment, if Figure 5 , Figure 8 As shown, the lifting assembly 3 includes a fixed seat 31, a cam 32, a second transmission wheel 33, a third transmission wheel 34, a second synchronous belt 35, a transmission shaft 36 and a second driving member 37; The second transmission wheel 33 and the third transmission wheel 34 are arranged at intervals, the second synchronous belt 35 is arranged on the second transmission wheel 33 and the third transmission wheel 34, the transmission shaft 36 passes through the fixed seat 31, and the third transmission wheel 34 and the cam 32 are arranged on the transmission shaft 36, the heating platform 2 is arranged in the fixed seat 31, and the cam 32 is arranged at the bottom of the heating platform 2. The second driving member 37 rotates to drive the second transmission wheel 33, the third transmission wheel 34 and the cam 32 to rotate, thereby driving the heating platform 2 to rise. Specifically, the application of the cam 32 mechanism can provide precise displacement control; by rotating the cam 32, the precise lifting and lowering adjustment of the heating platform 2 can be achieved, ensuring the stability and accuracy of the heating platform 2 during the lifting process, avoiding inaccurate positioning caused by mechanical errors, and ensuring the stability of the chip during the welding process; the movement generated by the rotation of the cam 32 can be effectively converted into the up and down displacement of the heating platform 2, ensuring that the rising and falling movements of the heating platform 2 are smooth and controllable, thereby ensuring the precise progress of the welding process.
[0032] Among them, continue to refer to Figure 5Guide blocks 311 are provided on both sides of the fixed seat 31, and second sliders 311a are provided on the side walls of the guide blocks 311. Second slide rails 21 are provided on the corresponding sides of the heating platform 2. The second sliders 311a move along the second slide rails 21, effectively guiding the movement trajectory of the heating platform 2, preventing the platform from tilting or offsetting during the lifting process, and ensuring that the movement of the platform is more stable and smooth; the cooperation between the second slide rails 21 and the second slider 311a reduces the friction problem that may exist in the traditional mechanical connection method when the heating platform 2 moves up and down, reduces the wear on the guide system and the heating platform 2 during long-term use, and extends the service life of the equipment.
[0033] As a preferred embodiment of the above embodiment, a tension spring 38 is provided between the four sides of the heating platform 2 and the bottom of the fixed seat 31, which is used to pull and reset the heating platform 2. The tension spring 38 provides a reverse force through elastic recovery, ensuring that the heating platform 2 can be accurately reset to the set position after the lifting is completed, which can reduce the deviation caused by mechanical errors or external interference, ensure that the heating platform 2 is always in the correct position, and avoid welding errors caused by the platform deviating from the position.
[0034] In this embodiment, if Figure 6 , Figure 7 As shown, a limiting groove 341 is provided on the third transmission wheel 34, and a limiting block 312 is provided on the fixing seat 31. The limiting block 312 is arranged in the limiting groove 341, and is used to control the rotation angle of the third transmission wheel 34, thereby controlling the rotation angle of the cam 32. The design of the limiting groove 341 and the limiting block 312 can accurately limit the rotation angle of the third transmission wheel 34, thereby realizing precise control of the rotation angle of the cam 32. Since the rotation angle of the cam 32 directly determines the lifting process of the heating platform 2, by limiting the rotation angle, the lifting accuracy of the heating platform 2 can be ensured, and operational errors caused by angle deviation can be avoided; the cooperation of the limiting groove 341 and the limiting block 312 provides physical structural restrictions, prevents excessive rotation of the third transmission wheel 34 and the cam 32, and reduces overload or malfunction that may occur in the equipment during operation.
[0035] The present invention also includes a working method of the welding transmission device for wire bonding as described above, comprising: S10: The first push rod 41 drives the chip to the heating platform 2 area; S20: The lifting assembly 3 drives the heating platform 2 to rise, and the positioning holes 22 and the air intake holes 23 position the chip to perform wire bonding welding operations; S30: After the welding is completed, the lifting assembly 3 drives the heating platform 2 to descend; S40: The second push rod 42 drives the chip to the next process.
[0036] At the same time, the first push rod 41 and the second push rod 42 are reset to prepare for the wire bonding welding of the next chip; since the push rod system can operate accurately and quickly, the waiting time is reduced and the assembly line speed of the production line is improved; the lifting component 3 drives the heating platform 2 to rise, and the positioning hole 22 and the air suction hole 23 accurately position the chip. This precise positioning can ensure the correct alignment of the chip during the welding process, avoid poor welding problems caused by chip offset, and thus improve the welding quality.
[0037] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
