Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper bar detection, in particular to a copper bar production surface detection equipment. BACKGROUND

[0002] As a key conductive connecting piece in power systems and electrical equipment, the surface flatness of the copper bar directly affects the conductivity, connection reliability and service life. If there are protrusions, depressions, scratches and other uneven defects on the surface, when connected with other components, it will cause the contact area to decrease and the contact resistance to increase, resulting in local heating, and in severe cases, it may cause circuit failure or even safety hazards, so the surface needs to be detected.

[0003] The existing copper bar surface detection equipment relies on external driving sources such as motors and air cylinders to realize the transmission of the copper bar and the movement of the detection assembly, which not only increases the energy consumption and manufacturing cost of the equipment, but also easily affects the continuity of detection due to the failure of the driving components. At the same time, the detection assembly is mostly fixed position detection or single direction movement, the detection range is limited, it is difficult to cover all areas of the copper bar surface, there is a detection blind area, resulting in some surface defects being missed, and it cannot meet the high-precision detection requirement. SUMMARY

[0006] Preferably, the buffer assembly comprises a fixed frame fixedly connected on both sides of the outer wall of the material guide groove, a rotating shaft is rotatably connected to the end of the fixed frame, a buffer frame is fixedly connected to the end of the rotating shaft, a torsional spring is installed between the fixed frame and the buffer frame, the torsional spring is used to resist the downward deflection of the buffer frame, and rubber wheels are rotatably connected to the bottom of both sides of the buffer frame.

[0007] Preferably, the detection assembly comprises a sliding block slidingly connected inside the fixed plate, one side of the outer wall of the sliding block is fixedly connected with a connecting plate, the outer portion of the connecting plate is slidingly connected with a mounting shell, the inner portion of the mounting shell is installed with an electronic dial gauge, and the outer wall of the connecting plate and the compensation plate is installed with a sensing assembly.

[0008] Preferably, the sensing assembly comprises a photoelectric sensor fixedly connected to the other side of the bottom end of the compensation plate and an electromagnet fixedly connected to the outer wall of the connecting plate, the outer wall of the mounting shell is fixedly connected with an iron block at the position corresponding to the electromagnet, and the inner portion of the mounting shell is installed with a spring sheet between the electromagnet and the iron block.

[0009] Preferably, the sensing assembly further comprises a control unit installed on the equipment, and the photoelectric sensor is used to realize electrical connection with the electromagnet in combination with the control unit.

[0010] Preferably, the transmission assembly comprises a gear rotatingly connected to the inner wall of the top of the bearing frame on both sides, the outer wall of the gear is respectively meshingly connected with the corresponding toothed plate, one side of the end face of the gear is rotatingly connected with a connecting rod, the distal end of the connecting rod is rotatingly connected with a sliding block, and the outer wall of the sliding block is slidingly connected inside the fixed plate.

[0011] Preferably, the inner wall of the material guide groove is fixedly connected with a sponge layer, and the sponge layer is in full contact with the surface of the copper bar through extrusion deformation.

[0012] Preferably, the bottom end of the sliding rod is fixedly connected with a receiving plate, the top of the receiving plate is provided with a receiving groove for preventing the copper bar from toppling, and the bottom end of the bearing frame is fixedly connected with a sponge pad for reducing impact receiving.

[0013] Working principle: the copper bar to be detected is put into the material guide groove on the top of the bearing frame, and slides downward along the material guide groove under the action of gravity. The sponge layer on the inner wall of the material guide groove is in full contact with the surface of the copper bar through extrusion deformation to clean the surface or reduce scratches during sliding. The copper bar contacts the rubber wheel at the bottom of the buffer frame during the downward sliding process, which pushes the buffer frame to deflect downward around the rotating shaft at the end of the fixed frame. The torsional spring between the fixed frame and the buffer frame generates a reverse elastic force to resist the deflection. The downward speed of the copper bar is reduced through the contact friction between the rubber wheel and the copper bar and the buffering force of the torsional spring. The stopper rod descends at the same time as the copper bar descends, which pushes the sliding rod to slide downward along the guide rail on the outer wall of the compensation plate. The toothed plates on both sides of the outer wall of the sliding rod move downward synchronously with the sliding rod and engage with the gears on both sides of the inner wall of the top of the bearing frame, which drives the gears to rotate. The connecting rod on one side of the end face of the gear swings, which pushes the sliding block to slide back and forth inside the fixed plate. The sliding block brings the connecting plate to move synchronously when it slides, and the electronic dial gauge moves back and forth with the connecting plate. When the copper bar descends until the photoelectric sensor on the other side of the bottom end of the compensation plate detects the position of the copper bar, the electromagnet on the outer wall of the connecting plate is powered off by the control unit on the equipment, the iron block at the corresponding position on the outer wall of the mounting shell is separated from the adsorption of the electromagnet, and the spring sheet between the electromagnet and the iron block provides an elastic force to make the detection needle of the electronic dial gauge tightly adhere to the surface of the copper bar. The detection of the flatness of the surface of the copper bar is realized through the back-and-forth movement of the electronic dial gauge. After the detection is completed, the copper bar continues to slide downward and falls onto the receiving plate at the bottom end of the sliding rod. The receiving groove above the receiving plate prevents the copper bar from falling over, and the sponge pad at the bottom end of the bearing frame reduces the impact when the copper bar falls into the receiving plate. The whole detection process is completed. After the detection is completed, the copper bar in the receiving groove can be taken out, and the sliding rod can be reset to repeat the above process to detect the subsequent copper bar.

[0014] The present application provides a copper bar production surface detection equipment. It has the following advantages: 1. The present application uses the gravity of the copper bar itself as the transmission power, without the need for additional driving sources to realize the downward sliding transmission of the copper bar in the material guide groove. The copper bar relies on gravity to push the stopper rod to move the sliding rod, and then the detection assembly works through the linkage of toothed plates, gears and other structures, greatly reducing the use of driving components such as motors and air cylinders, reducing the energy consumption, manufacturing cost and failure probability of the equipment, and simplifying the structure of the equipment, improving the operation stability.

[0015] 2. The present application significantly increases the detection area through multiple linkage structures. The downward sliding of the copper bar drives the movement of the sliding rod and the toothed plate. The engagement of the toothed plate and the gear makes the connecting rod push the sliding block to slide back and forth inside the fixed plate, and then drives the electronic dial gauge to move horizontally along the surface of the copper bar. Combined with the longitudinal downward sliding of the copper bar itself, a back-and-forth scanning detection of the surface of the copper bar is formed, ensuring that the detection of the flatness of the surface of the copper bar covers a wider range, and improving the reliability of the detection results.
