Description

Technical Field

[0001] This invention belongs to the field of combined processing machinery technology, and in particular relates to a chiseling device for electronic component mounting plates. Background Technology

[0002] In the processing of electronic component mounting boards, cutting equipment is used to precisely process various mounting holes, wire grooves and positioning grooves, providing a basic structure for component fixing, circuit layout and structural assembly. It is a key processing equipment to achieve a stable connection between the mounting board and electronic components, such as the electronic component mounting board cutting equipment disclosed in patent publication number CN113894548B.

[0003] Currently, when drilling holes in electronic component mounting boards, the drilling tool exerts continuous pressure on the mounting board as it moves downward. Although a support structure is usually set at the bottom of the mounting board, a clearance hole needs to be reserved at the corresponding position of the support to avoid collision damage when the tool drills through the mounting hole and comes into contact with the support structure. However, the existence of this clearance hole means that the support force in the center area drilled by the tool is still insufficient, and the mounting board is still prone to slight deformation at the drilling position, which may affect the stable installation of subsequent electronic components. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] like Figures 1-6 As shown, an electronic component mounting plate chiseling device includes a support frame 1 and an industrial control box 2 fixedly installed at one end of the support frame 1. A fixing unit 3 is installed on the support frame 1 and is used to fix the mounting plate. It also includes a movable frame 4, which is sleeved on the outside of the support frame 1. The support frame 1 is equipped with a lead screw drive mechanism 5, which is used to drive the movable frame 4 to move horizontally along the support frame 1. The lead screw drive mechanism 5 includes two reciprocating lead screws, a lead screw nut, a pulley assembly, a bearing, a drive motor, a moving block, and other components. The drive motor drives the two reciprocating lead screws to rotate through the pulley assembly, and the two reciprocating lead screws drive the movable frame 4 to move through the lead screw nut and the moving block.

[0020] The drilling unit 6 is located inside the upper side of the movable frame 4 and is used to drill holes in the mounting plate. The support column 7 is located inside the support frame 1 and is coaxial with the drilling unit 6. The movable frame 4 is equipped with a support unit 8, which provides support force to the support column 7. The drive unit 9 is located on the end face of the movable frame 4 and is used to drive the support unit 8 and the drilling unit 6 to move. The grinding unit 10 is located inside the movable frame 4 and is used to grind the mounting plate.

[0021] The fixing unit 3 includes two clamping frames 31 that are slidably disposed on the top of the support frame 1. Two pressure plates 32 are slidably connected to the inner side of each clamping frame 31, and clamping screws 33 are rotatably connected to the end face of each pressure plate 32. Both clamping screws 33 are threadedly connected to the end face of the support frame 1 on the same side, which can facilitate stable clamping and fixing of the mounting plate.

[0022] The drilling unit 6 includes a rotary drive mechanism 61, on the drive end of which a detachable drill bit 62 is mounted. A hydraulic cylinder 63 is mounted above the rotary drive mechanism 61, and the movable end of the hydraulic cylinder 63 is fixedly connected to the mounting end of the rotary drive mechanism 61. Both the rotary drive mechanism 61 and the hydraulic cylinder 63 are electrically connected to the industrial control box 2. The support column 7 has the same diameter as the drill bit 62. The rotary drive mechanism 61 includes components such as a motor, shaft, bearing, and mounting box. The motor drives the drill bit 62 to rotate through the shaft.

[0023] The support unit 8 includes a support base 81, a support column 7 is fixedly installed on the top of the support base 81, and an elastic telescopic rod 82 is provided below the support base 81. The movable end of the elastic telescopic rod 82 is rotatably connected to the support base 81. The elastic telescopic rod 82 includes components such as a telescopic rod, a cylinder, a limiting slider, and an elastic element.

[0024] The drive unit 9 includes two movable blocks 91. The upper and lower ends of the movable frame 4 are provided with strip holes 92 that match the movable blocks 91. The elastic telescopic rod 82 and the hydraulic cylinder 63 are fixedly inserted into the movable blocks 91 on the same side. Electric push rods 93 are fixedly inserted into the hole walls of the two strip holes 92, and the movable ends of the two electric push rods 93 are fixedly connected to the movable blocks 91 on the same side. The two electric push rods 93 are electrically connected to the industrial control box 2, which can facilitate the adjustment of the drilling and support positions.

[0025] The grinding unit 10 includes a support ring 101 sleeved on the outside of the elastic telescopic rod 82, and a rotating plate 102 rotatably connected to the outer wall of the support ring 101. Multiple support rods 103 are provided on the end face of the rotating plate 102, and a lower grinding ring 104 is fixedly connected to the end of each support rod 103. The lower grinding ring 104 is slidably sleeved on the outside of the support column 7. An upper grinding ring 105 is fixedly sleeved on the drill bit 62. A detachable annular grinding pad 106 is installed on the opposite end of the upper grinding ring 105 and the lower grinding ring 104. Friction plates 107 are fixedly connected to the end face of the rotating plate 102 and the bottom of the support seat 81. A lifting assembly 11 is installed on the end face of the rotating plate 102, and the rotating plate 102 is connected to each support rod 103 through the lifting assembly 11. The friction plates 107 can increase the friction between the rotating plate 102 and the support seat 81, ensuring that the support seat 81 can drive the rotating plate 102 to rotate smoothly.

[0026] The lifting assembly 11 includes multiple passive cylinders 111 and multiple active cylinders 112 fixedly inserted into the end face of the rotating plate 102. Pistons 113 are slidably connected inside both the active and passive cylinders 111, and support springs 114 are fixedly installed between the active and passive cylinders 112 and the pistons 113 on the same side. A pressing rod 115 is slidably connected to the top of the active cylinder 112, and the pressing rod 115 is located below the support base 81. A lifting rod 116 is slidably connected to the top of the passive cylinders 111, and the lifting rod 116... 6 is fixedly connected to the support rod 103 on the same side. The lifting rod 116 and the pressing rod 115 are both fixedly connected to the end face of the piston 113 on the same side. A connecting pipe 117 is fixedly inserted between the active cylinder 112 and the passive cylinder 111 on the same side. The connecting pipe 117 is located on the lower side of the two pistons 113 on the same side. The interior of the active cylinder 112 and the passive cylinder 111 is filled with hydraulic oil in the position below the piston 113. This allows the annular grinding pad 106 on the top of the lower grinding ring 104 to abut against the bottom of the mounting plate, ensuring sufficient grinding pressure.

[0027] An encoder 12 is fixedly installed on the movable end of the elastic telescopic rod 82, and the rotating end of the encoder 12 is fixedly connected to the bottom of the support base 81. When the support base 81 rotates once, the encoder 12 will send an electrical signal back to the industrial control box 2. This can roughly estimate the wear condition of the drill bit 62 and promptly remind the staff to replace the drill bit 62 when it is excessively worn.

[0028] The operating principle of the present invention is explained as follows: The mounting plate to be processed is inserted into the two clamping frames 31, and then the clamping screw 33 is turned to make the clamping plate 32 move down, thereby clamping and fixing the mounting plate (the position of the mounting plate can be accurately installed by installing positioning columns or measuring dimensions, etc.). Then the industrial control box 2 is started to start the chiseling work. The industrial control box 2 first controls the screw drive mechanism 5 to work (the screw drive mechanism 5 includes two reciprocating screws, a screw nut, a pulley assembly, bearings, a drive motor, a moving block, etc. The drive motor drives the two reciprocating screws to rotate through the pulley assembly, and the two reciprocating screws drive the movable frame 4 to move through the screw nut and the moving block), so that the screw drive mechanism 5 drives the movable frame 4 to move to the designated drilling position according to the preset program. Subsequently, the industrial control box 2 controls the hydraulic cylinder 63 and the rotary drive mechanism 61 to work (the rotary drive mechanism 61 includes a motor, a shaft, bearings, a mounting box, etc., and the motor drives the hydraulic cylinder 63 through the shaft). (The drill bit 62 rotates), and the hydraulic cylinder 63 can drive the rotary drive mechanism 61 and the drill bit 62 to move downwards. The rotary drive mechanism 61 can drive the drill bit 62 to rotate, so that the drill bit 62 moves to the position to be drilled on the mounting plate. At this time, the drill bit 62 can drill a hole in the mounting plate. Initially, the support column 7 is in contact with the bottom of the mounting plate, so that the support column 7 can support the drilling position of the mounting plate from the bottom of the mounting plate. Since the support column 7 and the drill bit 62 are coaxial, the support column 7 can support the mounting plate from the center axis of the hole, resulting in higher support strength and making the mounting plate less prone to deformation. As the drill bit 62 moves downwards and penetrates the mounting plate, it will abut against the top of the support column 7. At this time, the drill bit 62 will press down on the support column 7, causing the support column 7 and the support seat 81 to move downwards synchronously, thereby compressing the elastic element inside the elastic telescopic rod 82. Since the support seat 81 is rotatably connected to the movable end of the elastic telescopic rod 82, the support column 7 and the support seat 81 can rotate synchronously with the drill bit 62. Therefore, the support column 7 will not obstruct the drill bit 62, thus preventing damage to the drill bit 62. Secondly, as the drill bit 62 descends deeper, the annular grinding pad 106 at the bottom of the upper grinding ring 105 fitted on the drill bit 62 abuts against the top of the mounting plate. Simultaneously, during the downward movement of the support base 81, it first pushes the extrusion rod 115 downward, causing the piston 113 on the same side as the extrusion rod 115 to descend. This allows the hydraulic oil inside the active cylinder 112 to be extruded into the passive cylinder 111 on the same side through the connecting pipe 117, causing the piston 113 inside the passive cylinder 111 to rise. Then, through the lifting rod 116 and the support rod 103, the annular grinding pads 106 at the top of each lower grinding ring 104 abut against the lower end of the mounting plate. At the same time, the friction plate 107 at the bottom of the support base 81 and the friction plate 107 at the top of the rotating plate 102 abut against each other (the friction plate 107 can increase the height of the rotating plate 102 and the support base 81). (Roughness of the end face of support 81) When the drill bit 62 rotates, it will drive the upper grinding ring 105 to rotate. The drill bit 62, through the support column 7, support 81, and friction plate 107, can drive the rotating plate 102 to drive the lower grinding ring 104 to rotate synchronously. Thus, after the drill bit 62 penetrates the mounting plate, the annular grinding pads 106 on both sides can grind the upper and lower edges of the drilled hole, thereby removing the burrs on the hole edges. By integrating edge grinding and drilling together, and the drill bit 62 can complete the edge grinding design in one drilling operation, the processing efficiency can be effectively improved. (Among them, a limit switch is installed at the hydraulic cylinder 63. The industrial control box 2 can control the extension distance of the hydraulic cylinder 63 through the electrical signal fed back by the limit switch, ensuring that the hydraulic cylinder 63 can stop working in time when the upper grinding ring 105 moves to the designated position.) Simultaneously, after the drill bit 62 penetrates the mounting plate, the industrial control box 2 controls the encoder 12 to work immediately. After the upper grinding ring 105 moves to the designated position, the industrial control box 2 controls the encoder 12 to stop working (the industrial control box 2 controls the encoder 12 based on the travel distance of the hydraulic cylinder 63 fed back by the limit switch at the hydraulic cylinder 63). During this period (i.e., from after the drill bit 62 penetrates the mounting plate until the upper grinding ring 105 moves to the designated position), the encoder 12 sends an electrical signal to the industrial control box 2 for each revolution of the support base 81 as the drill bit 62 rotates. At this time, the counting module of the industrial control box 2 counts. If the wear on the drill bit 62 is small and the drilling of the mounting plate is minimal... With high efficiency and a smooth inner wall of the hole, the drill bit 62 can rotate smoothly after penetrating the mounting plate. Therefore, the number of electrical signals received by the industrial control box 2 is relatively stable and within the threshold range. Conversely, when the drill bit 62 is excessively worn, the hole becomes rough due to wear, and the contact area between the drill bit 62 and the hole is large. Under the same power of the rotary drive mechanism 61, the number of rotations of the drill bit 62 decreases, so the number of electrical signals measured by the industrial control box 2 is relatively low. When the count is lower than the threshold, the industrial control box 2 will immediately issue a voice alarm to remind personnel to check and replace the drill bit 62 (the threshold is set based on parameters such as the material of the drill bit 62 and the material of the mounting plate).
