Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a chip welding device for sensor processing. Background Technology

[0002] Sensor chips are core components in industrial automation, used to convert physical signals into electrical signals for precise monitoring and control. For example, in the production of temperature sensors, the sensor chip needs to be soldered. Existing soldering equipment has a simple structure, cumbersome material positioning and clamping, poor stability, and is difficult to install and disassemble, thus affecting soldering efficiency.

[0003] Those skilled in the art have researched and improved upon this, as exemplified by an automatic chip insertion and welding device for temperature sensors (application number CN202321400578.7). This technical solution, combined with an auxiliary insertion bracket structure installed simultaneously with a connecting plate and welded welding heads, enables simultaneous chip insertion and welding operations. However, this solution still has shortcomings: manual unloading is required after welding, and the stability of the mounting plate during movement cannot be guaranteed, affecting the overall performance. Therefore, we propose a chip welding device for sensor processing. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention has a reasonable structural design.

It can automatically complete the unloading of another set of sensor chips while one set of sensor chips is being welded, which is convenient and fast.

[0017] 2. In this invention, the guide sleeve slides along the guide rod, and the C-shaped slider slides along the horizontal part of the T-shaped rail.

[0018] 3. In this invention, when the positioning platform abuts against the press switch, the screw motor starts; when the welding frame is lowered to the low position, the welding head completes chip welding; after the conductive terminal is separated from the conductive metal strip, the electromagnet is de-energized; after the deflection bar rotates, the push plate pushes the material out of the mold groove; then, the spur gear is meshed with the spur gear, and the flipping shaft can drive the positioning platform to flip; after the mold groove opening faces downward, the material falls into the buffer cloth for unloading and transfer.

[0019] In summary, this device, with its dual-station setup, can complete one set of unloading operations while one set of welding operations is being performed. During the longitudinal translation of the positioning table, the electromagnet is energized to generate magnetism, which can position and press the material to prevent displacement and ensure welding accuracy. When the positioning table is above the unloading port, it flips over, and the push plate can automatically push the material out of the mold groove, making unloading more convenient and faster.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] Please see Figure 1-9As shown, this embodiment is a chip welding device for sensor processing, including a workbench 1. Lifting rings 2 are connected to the four corners of the top of the workbench 1 for hoisting and transferring the device as a whole. Guide rods 3 are connected to the left and right sides of the top of the workbench 1. A T-rail 4 is connected to the middle section of the top of the workbench 1. A sliding sleeve assembly 5 is fitted around the guide rods 3. Sliding slider assemblies 6 are slidably connected to the left and right ends of the T-rail 4. A positioning platform 7 is installed between the sliding sleeve assembly 5 and the sliding slider assembly 6. The positioning platform 7's position changes back and forth, facilitating material loading and unloading and welding operations. A docking platform 8 is connected to the rear top of the workbench 1. Welding seats 9 are connected to the left and right sides of the top of the docking platform 8, facilitating welding processing of materials on the positioning platform 7. A PLC controller 10 is connected to the outer wall of the workbench 1.

[0034] The top of the positioning platform 7 is provided with a groove 701 to facilitate the installation of the sensor chip. The bottom of the groove 701 is connected to a power cavity 702. A central shaft 703 is fixedly connected inside the power cavity 702. A deflection bar 704 is rotatably connected to the outside of the central shaft 703. Slide rails 705 are provided on both the left and right sides of the deflection bar 704. I-beam blocks 706 are slidably connected inside the slide rails 705. Vertical rods 707 are hinged to the outer wall of the I-beam blocks 706 by a pin. A push plate 708 is fixedly connected to the upper end of one set of vertical rods 707 to push out the material. A free telescopic rod 709 is connected between the push plate 708 and the bottom wall of the groove 701 to ensure that the push plate 708 moves linearly. A magnetic metal plate 710 is fixedly connected to the lower end of the other set of vertical rods 707.

[0035] The top left and right sides of the positioning platform 7 have rectangular holes 711, and a square rod 712 is movably inserted into the rectangular holes 711. The lower end of the square rod 712 is fixed to a magnetic metal plate 710. The square rod 712 moves vertically up and down with the magnetic metal plate 710. A vertical toothed groove 713 is opened on the side of the square rod 712 near the groove 701. The top left and right sides of the positioning platform 7 are connected to side brackets 714. A drive shaft 715 is rotatably connected in the side brackets 714. A driven gear 716 is connected to the outer wall of the drive shaft 715. Wheel 716 meshes with vertical toothed groove 713. A pressure arm 717 is connected to the end of drive shaft 715. A silicone pressure block 718 is installed at the lower end of pressure arm 717. Pressure arm 717 deflects with drive shaft 715. Silicone pressure block 718 can position and press materials. An electromagnet 719 is embedded at the bottom of positioning table 7. When energized, it can attract magnetic metal plate 710. Two compression springs 720 are connected between magnetic metal plate 710 and positioning table 7. Compression springs 720 are sleeved on the outside of square rod 712.

[0036] The specific method of this embodiment is as follows:

[0037] When using this device, the workbench 1 is placed in the work area and connected to an external power source. The PLC controller 10 controls the operation of each electrical component. After the chip is installed into the sensor, it is placed in the slot 701 and supported by the push plate 708. The guide rod 3 and the T-rail 4 are used for limiting and guiding. The sliding sleeve assembly 5 and the slider assembly 6 can move in the front and back direction, thereby adjusting the longitudinal position of the positioning table 7. When the rear end of the positioning table 7 abuts against the docking table 8, it reaches the welding station. The chip is welded and packaged using the welding seat 9.

[0038] During the movement of the positioning platform 7, the electromagnet 719 is energized and magnetized, and guided by the rectangular hole 711, the magnetic metal plate 710 is attracted and drives the square rod 712 and a set of vertical rods 707 to move upward. The I-beam block 706 can slide along the slide rail 705, so that the deflection bar 704 rotates around the central axis 703. Another set of vertical rods 707 pulls the push plate 708 into the groove 701. After the square rod 712 moves upward, the vertical tooth groove 713 meshes with the driven gear 716. The transmission shaft 715 can drive the pressure arm 717 to deflect downward. The silicone pressure block 718 presses and positions the material to ensure that the welding work can be carried out stably.

[0039] Example 2

[0040] Based on Embodiment 1, the sliding sleeve assembly 5 includes a guide sliding sleeve 501 sleeved on the outside of the guide rod 3. A linkage rod 107 is fixedly connected to the side of the guide sliding sleeve 501 away from the positioning table 7. An L-shaped frame 502 is connected to the side of the guide sliding sleeve 501 close to the positioning table 7. A reinforcing rib 503 is welded between the horizontal part of the L-shaped frame 502 and the guide sliding sleeve 501 to enhance the structural strength. A flipping shaft 504 is rotatably connected to the vertical part of the L-shaped frame 502. One end of the flipping shaft 504 is fixedly connected to the outer wall of the positioning table 7 to facilitate the flipping of the positioning table 7 for unloading. A spur gear 505 is fixedly connected to the other end of the flipping shaft 504. A torsion spring 506 is connected between the vertical part of the L-shaped frame 502 and the positioning table 7. The torsion spring 506 is sleeved on the outside of the flipping shaft 504 to provide elastic reset after the positioning table 7 flips. Limiting strips 507 are connected to the left and right sides of the inner wall of the guide sliding sleeve 501 to ensure stable forward and backward operation.

[0041] The slider assembly 6 includes a C-shaped slider 601 sleeved on the horizontal part of the T-shaped rail 4. A second flip shaft 602 is rotatably connected to the outer wall of the C-shaped slider 601. A positioning platform 7 is fixedly connected to the end of the second flip shaft 602. The second flip shaft 602 and the first flip shaft 504 are arranged coaxially to facilitate the control of the positioning platform 7 flipping. A second torsion spring 603 is connected between the C-shaped slider 601 and the positioning platform 7. The second torsion spring 603 is sleeved on the outside of the second flip shaft 602. The inner wall of the C-shaped slider 601 has upper and lower receiving openings 604. Metal balls 605 are installed in the receiving openings 604. The ends of the metal balls 605 abut against the T-shaped rail 4 to reduce friction. A fixing frame 606 is connected to the bottom of the C-shaped slider 601. Two conductive terminals 607 are installed in the fixing frame 606. The two conductive terminals 607 are connected in series in the working circuit of the electromagnet 719 through wires.

[0042] The guide rod 3 has limit grooves 301 on the left and right sides of its outer wall that cooperate with the limit strip 507 to ensure that the guide sleeve 501 moves stably in the front and back direction. The bottom front side of the guide rod 3 is connected to a rack 302, which meshes with a spur gear 505. The flip shaft 504 drives the positioning table 7 to flip and unload. The vertical part of the T-rail 4 is connected to a conductive metal strip 401. The end of the conductive terminal 607 abuts against the conductive metal strip 401, so that the electromagnet 719 remains energized and magnetized during the movement of the positioning table 7. The conductive metal strip 401 is located behind the rack 302.

[0043] The specific method of this embodiment is as follows:

[0044] In this embodiment, after the positioning platform 7 completes the material loading, it moves toward the docking platform 8. The guide sleeve 501 is movably sleeved on the outside of the guide rod 3. The limiting strip 507 and the limiting groove 301 are configured to ensure the stable movement of the guide sleeve 501. The C-shaped slider 601 is sleeved on the horizontal part of the T-shaped rail 4. Metal balls 605 are installed in the receiving opening 604. The end of the metal balls 605 abuts against the T-shaped rail 4 to reduce friction. The fixing frame 606 moves synchronously with the C-shaped slider 601. During the movement, the two conductive terminals 607 will contact the conductive metal strip 401 at the same time. At this time, the electromagnet 719 connected in series with the conductive terminals 607 remains energized and generates magnetism, which can attract the magnetic metal plate 710.

[0045] After the chip soldering is completed, the positioning stage 7 is moved to the front of the guide rod 3. At this time, the rack 302 meshes with the spur gear 505, and the first flip shaft 504 drives the positioning stage 7 to flip so that the opening of the groove 701 faces downward. At this time, the conductive terminal 607 disengages from the conductive metal strip 401. After the electromagnet 719 is de-energized, the compression spring 720 drives the magnetic metal plate 710 to reset. The vertical rod 707 can pull the I-block 706 to slide. After the deflection bar 704 rotates, the push plate 708 pushes the material out of the groove 701 for unloading. When the spur gear 505 disengages from the rack 302, the first torsion spring 506 and the second torsion spring 603 perform elastic reset, so that the positioning stage 7 flips again so that the opening of the groove 701 faces upward.

[0046] Example 3

[0047] Based on Embodiment 2, the worktable 1 has stroke grooves 101 at both ends. A longitudinal screw 102 is rotatably connected in the stroke groove 101. The two longitudinal screws 102 are arranged in opposite directions. The rear end of the longitudinal screw 102 is connected to a synchronous pulley 103. A transmission belt 104 is sleeved between the outer walls of the two synchronous pulleys 103. The front end of the worktable 1 is connected to a forward and reverse motor 105. The output end of the forward and reverse motor 105 is fixedly connected to the longitudinal screw 102 through a coupling. A nut seat 106 is screwed onto the outer wall of the longitudinal screw 102. A linkage rod 107 is connected between the nut seat 106 and the sliding sleeve assembly 5 to facilitate the longitudinal movement of the sliding sleeve assembly 5.

[0048] The front end face of the welding seat 9 has a vertical groove 901. The top of the vertical groove 901 is connected to a lead screw motor 902. The bottom output end of the lead screw motor 902 is connected to a bidirectional reciprocating lead screw 903. A lifting block 904 is screwed to the outer wall of the bidirectional reciprocating lead screw 903. The front end of the lifting block 904 is connected to a welding frame 905. A welding head 906 is installed at the bottom of the welding frame 905. Two push switches 801 are installed on the front end face of the docking platform 8. The push switches 801 are located directly behind the positioning platform 7. The push switches 801 are electrically connected to the corresponding lead screw motor 902. After the lead screw motor 902 is started, the bidirectional reciprocating lead screw 903 rotates, and pushes the lifting block 904 placed in the spiral groove to make axial reciprocating motion through the side of its spiral groove.

[0049] The bottom of the workbench 1 is connected to the four corners of the support legs 111. The front end of the workbench 1 has two unloading ports 112. The bottom left and right sides of the unloading ports 112 are connected to triangular plates 113. The bottom walls of the two triangular plates 113 are connected to a buffer cloth 114 to facilitate the transfer of the welded sensor. The unloading ports 112 are located between two straight racks 302.

[0050] The specific method of this embodiment is as follows:

[0051] In this embodiment, the longitudinal screw 102 is rotated by the forward and reverse motor 105. The two longitudinal screws 102 are set in opposite directions of rotation. The synchronous pulley 103 and the transmission belt 104 are used for transmission, so that the two longitudinal screws 102 rotate in opposite directions. The nut seat 106 can move longitudinally along the stroke groove 101, thereby controlling the two positioning tables 7 to move in opposite directions. This allows the unloading of one set of sensor chips while one set of sensor chips is being welded.

[0052] When the positioning platform 7 moves below the welding frame 905, it abuts against the push switch 801. At this time, the docking platform 8 is close to the positioning platform 7 for limit, to prevent the positioning platform 7 from shaking during welding. The lead screw motor 902 drives the bidirectional reciprocating lead screw 903 to rotate, and pushes the lifting block 904 placed in the spiral groove to make axial reciprocating motion through the side of its spiral groove. This can control the vertical lifting and lowering of the welding frame 905. When the welding frame 905 is in the low position, the welding head 906 performs welding on the sensor and chip mounting location. At this time, another set of positioning platforms 7 is located directly above the unloading port 112 and is flipped to facilitate the unloading operation.
