[0016] In summary, by applying the technical solution of the present invention, the following beneficial effects are achieved: The structure of the present invention is reasonably designed. (1) A first slide rail is further provided on the mounting plate. The first slide rail includes a fixed part fixed to the mounting plate and a sliding part that can slide back and forth relative to the fixed part. A baffle fixed to the mounting plate is provided behind the first slide rail, and a spring is connected between the sliding part and the baffle. A connecting rod and a dust-proof and explosion-proof servo motor are fixed on the sliding part. The grinding wheels on the front upper side, front lower side, and rear lower side are respectively rotatably arranged on the connecting rod. The output end of the dust-proof and explosion-proof servo motor is in transmission cooperation with the grinding wheel on the front upper side or front lower side through a transmission belt. Thus, by directly connecting the dust-proof and explosion-proof servo motor with the front grinding wheel, the direct connection increases the power. Compared with the market, it makes a front-wheel drive, which further increases the cutting force of the front grinding wheel and abrasive belt close to the product to be ground, resulting in a fast processing speed and the abrasive belt is not easily broken (because in these two cases of front-wheel drive and rear-wheel drive, although the tension of the abrasive belt remains unchanged, in the process of grinding the gate, when the cutting power is insufficient, it is easy to cut off the abrasive belt by strong pressure on the gate). (2) A spring is connected between the sliding part of the first slide rail and the baffle. When the manipulator grabs the product to be ground from the material conveying rack and places it on the abrasive belt of the front grinding wheel for polishing, the front grinding wheel drives the connecting rod and the sliding part of the first slide rail to move backward in sequence after being stressed. Then the spring is compressed. Subsequently, during the continuous process of grinding the gate, the spring gradually returns forward. Thus, by using the buffering effect of the spring, the load of the manipulator is small, which further protects the manipulator and avoids over-grinding of the workpiece.

[0030] Refer to Figures 1 to 10, this embodiment provides a fully automatic manipulator abrasive belt machine for grinding gate, which includes a manipulator body 1, a material conveying frame 2 and an abrasive belt machine body 3. The manipulator body 1 and the material conveying frame 2 are arranged in front of the abrasive belt machine body 3. The abrasive belt machine body 3 includes a frame 4 and an abrasive belt mechanism 5 arranged on the frame 4. The abrasive belt mechanism 5 includes a mounting plate 501 and a plurality of grinding wheels 502. The plurality of grinding wheels 502 are respectively rotatably arranged on the front upper side, front lower side, rear upper side and rear lower side of the mounting plate 501. An abrasive belt 503 is wound around the plurality of grinding wheels 502; a first slide rail 6 is further arranged on the mounting plate 501. The first slide rail 6 includes a fixed part 601 fixed on the mounting plate 501 and a sliding part 602 that can slide back and forth relative to the fixed part 601. A baffle 7 fixed on the mounting plate 501 is arranged behind the first slide rail 6. A spring 8 is connected between the sliding part 602 and the baffle 7; a connecting rod 603 and a dust-proof and explosion-proof servo motor 604 are fixed on the sliding part 602. The grinding wheels 502 on the front upper side, front lower side and rear lower side are respectively rotatably arranged on the connecting rod 603. The output end of the dust-proof and explosion-proof servo motor 604 is in transmission cooperation with the grinding wheel 502 on the front upper side or front lower side through a transmission belt; an abrasive belt tensioning cylinder 9 is further arranged on the mounting plate 501. The grinding wheel 502 on the rear upper side is rotatably arranged on the driving end of the abrasive belt tensioning cylinder 9. Explanation: The abrasive belt tension can be adjusted through the abrasive belt tensioning cylinder. Function: (1) Since a first slide rail is further arranged on the mounting plate, the first slide rail includes a fixed part fixed on the mounting plate and a sliding part that can slide back and forth relative to the fixed part, a baffle fixed on the mounting plate is arranged behind the first slide rail, and a spring is connected between the sliding part and the baffle; a connecting rod and a dust-proof and explosion-proof servo motor are fixed on the sliding part, and the grinding wheels on the front upper side, front lower side and rear lower side are respectively rotatably arranged on the connecting rod. The output end of the dust-proof and explosion-proof servo motor is in transmission cooperation with the grinding wheel on the front upper side or front lower side through a transmission belt; thus, the dust-proof and explosion-proof servo motor is directly connected to the front grinding wheel, the direct connection increases the power, and a front drive is made in comparison with the market, so that the front grinding wheel and the abrasive belt close to the product to be ground have increased cutting force, the processing speed is fast, and the abrasive belt is not easily broken (because in these two cases of front drive and rear drive, although the abrasive belt tension does not change, but in the process of grinding the gate, when the cutting power is insufficient, the gate is easily forced to cut off the abrasive belt). (2) Since a spring is connected between the sliding part of the first slide rail and the baffle, when the manipulator grabs the product to be ground from the material conveying frame and places it on the abrasive belt of the front grinding wheel for polishing, the front grinding wheel drives the connecting rod and the sliding part of the first slide rail to move backward in sequence after being stressed, then the spring is compressed, and then during the continuous process of grinding the gate, the spring gradually returns forward, so that the buffer effect of the spring is utilized to make the load of the manipulator small, thereby protecting the manipulator and avoiding over-grinding of the workpiece.
[0031] Specifically, a movable hole 701 is provided in the middle of the baffle 7, and the middle of the rear end of the sliding part 602 is threadedly connected and fixed with the front end of the first screw rod 605. The rear end of the first screw rod 605 passes through the movable hole 701 and is provided with a first screw head 6051. The outer diameter of the first screw head 6051 is larger than the inner diameter of the movable hole 701. Function: The manipulator grabs the product to be ground on the material conveying rack and moves it to the sanding belt on the front grinding wheel for grinding gate treatment. After the front grinding wheel is subjected to force, it drives the connecting rod and the sliding part of the first slide rail to move backward in turn, and then the rear end of the first screw rod moves through the movable hole. In the process of the spring gradually returning forward, the first screw head limits the forward movement of the first screw rod, thereby limiting the forward movement of the sliding part of the first slide rail.
[0032] Specifically, the upper and lower sides of the baffle 7 are respectively provided with guide holes 702 that penetrate the front and back, and the upper and lower sides of the rear end of the sliding part 602 are respectively fixed with guide rods 801 extending backwards, and the guide rods 801 pass through the guide holes 702 of the baffle 7 backwards; the guide rods 801 on the upper and lower sides are respectively sleeved with springs 8, and the outer diameter of the spring 8 is larger than the inner diameter of the guide holes 702 of the baffle 7. Function: The manipulator grabs the product to be ground on the material conveying rack and moves it to the sanding belt on the front grinding wheel for grinding gate processing. After the front grinding wheel is subjected to force, it drives the connecting rod and the sliding part of the first slide rail to move backward in turn, and then the guide rod moves in the guide hole, the spring is compressed, and the baffle limits the amplitude of the sliding part of the first slide rail to move backward, and then in the process of continuing the grinding gate, the spring gradually resets forward. Therefore, due to the guiding effect of the guide rod and the guide hole, a large deviation in the movement direction of the spring can be avoided; and the upper and lower springs can better make the force distribution of the sliding part of the first slide rail more balanced.
[0033] Specifically, the first slide rail 6 is arranged on the inner side of the sanding belt 503, the connecting rod 603 is fixed to the side of the sliding part 602 close to the mounting plate 501, and the dustproof and explosion-proof servo motor 604 is fixed to the side of the sliding part 602 away from the mounting plate 501. Function: This makes it easier for the dustproof and explosion-proof servo to cooperate with the front grinding wheel on the connecting rod through the transmission belt. Preferably, the diameter of the grinding wheel that cooperates with the dustproof and explosion-proof servo through the transmission belt is larger than the diameter of other grinding wheels, so as to better drive the sanding belt.
[0034] Specifically, the abrasive belt tensioning cylinder 9 is arranged inside the abrasive belt 503, the driving end of the abrasive belt tensioning cylinder 9 faces backward, and a U-shaped block 901 is arranged behind the driving end of the abrasive belt tensioning cylinder 9; the U-shaped block 901 includes a connecting arm 9011 and two supporting arms 9012, and the two supporting arms 9012 are respectively arranged on the left and right sides of the rear end of the connecting arm 9011. The driving end of the abrasive belt tensioning cylinder 9 is connected to the connecting arm 9011, and the left and right ends of the upper rear grinding wheel 502 are respectively rotatably connected to the left and right connecting arms 9011. Function: By arranging the U-shaped block, the driving end of the abrasive belt tensioning cylinder can drive the upper rear grinding wheel to move back and forth better.
[0035] Specifically, an adjusting block 902 fixed to the mounting plate 501 is arranged behind the driving end of the abrasive belt tensioning cylinder 9. An adjusting opening 9021 penetrating through the front and rear is arranged on the adjusting block 902, and the connecting arm 9011 is arranged in the adjusting opening 9021; the driving end of the abrasive belt tensioning cylinder 9 is rotatably connected to the connecting arm 9011. Second screw rods 9022 are vertically arranged on the upper left side, upper right side, lower left side, and lower right side of the adjusting block 902 respectively. One end of the second screw rod 9022 can extend into the adjusting opening 9021 to abut against the U-shaped block 901, and a second screw head 9023 is arranged at the other end of the second screw rod 9022. Function: Since the driving end of the abrasive belt tensioning cylinder is rotatably connected to the connecting arm and the U-shaped block can rotate, when the second screw rods on the upper left side, upper right side, lower left side, and lower right side are adjusted differently, the U-shaped block will be driven to rotate to realize the up and down rotation adjustment of the U-shaped block, so as to realize the up and down balance adjustment of the abrasive belt. Preferably, the driving end of the abrasive belt tensioning cylinder is set as a rectangular parallelepiped driving plate 900, the long side of the driving plate 900 is in the up and down direction, the short side is in the left and right direction, and the width of the long side of the driving plate 900 is greater than the up and down width of the adjusting opening to limit the backward movement amplitude of the driving end of the abrasive belt tensioning cylinder.
[0036] Specifically, rotation holes 9013 penetrating left and right are respectively provided on the connecting arms 9011 on the left and right sides. The width of the rotation hole 9013 in the front-back direction is greater than the width in the up-down direction. The left and right ends of the central axis 5021 of the grinding wheel 502 on the upper rear side are respectively rotationally connected to the rotation holes 9013 on the left and right sides; a support block 9014 is provided on the support arm 9012 on the side of the U-shaped block 901 away from the mounting plate 501. The support block 9014 is arranged in front of the rotation hole 9013. A third screw rod 9015 is provided on the support block 9014. A third screw head 9016 is provided at the front end of the third screw rod 9015. The rear end of the third screw rod 9015 abuts against one end of the central axis 5021 away from the mounting plate 501; a vertical mounting hole 9017 is provided on the support arm 9012 on the side of the U-shaped block 901 close to the mounting plate 501. A fulcrum shaft passing through the rotation hole 9013 is provided in the vertical mounting hole 9017. The fulcrum shaft is arranged in front of or behind the central axis 5021. Function: When the fulcrum shaft is arranged in front of or behind one end of the central axis, the rear end of the third screw rod abuts against the other end of the central axis, so that the fulcrum shaft serves as the fulcrum for the front-back adjustment of the central axis. Through the front-back movement of the third screw rod, the front-back adjustment of the central axis driving the grinding wheel is realized, so as to realize the front-back balance adjustment of the abrasive belt.
[0037] Specifically, the number of the abrasive belt mechanisms 5 is set to two or more groups. The abrasive belt 503 of at least one group of the abrasive belt mechanisms 5 is set as a coarse grinding abrasive belt, and the abrasive belt 503 of at least one group of the abrasive belt mechanisms 5 is set as a fine grinding abrasive belt. Function: By setting the coarse grinding abrasive belt and the fine grinding abrasive belt, the manipulator can complete two processes of coarse grinding and fine grinding on a single abrasive belt machine with the product to be ground, improving work efficiency.
[0038] Specifically, the number of the abrasive belt mechanisms 5 is set to four groups. The four groups of abrasive belt mechanisms 5 are respectively arranged on the upper left side, lower left side, upper right side, and lower right side of the machine frame 4; among the abrasive belt mechanisms 5 on the left and right sides, the abrasive belts 503 of two groups of the abrasive belt mechanisms 5 on one side are set as fine grinding abrasive belts, and the abrasive belts 503 of two groups of the abrasive belt mechanisms 5 on the other side are set as coarse grinding abrasive belts. Function: Setting four groups of abrasive belts is to reduce the frequency of abrasive belt replacement; two abrasive belts can be installed for coarse grinding and fine grinding according to product requirements; when the abrasive belt is worn out, the next group of abrasive belts can be automatically switched to perform processing, reducing the waiting time in the process, improving the mechanical utilization rate, and at the same time reducing the number of mechanical care personnel, enabling one person to operate multiple machines. Two waste material recovery plates 401 are provided at the front end of the machine frame 4. One waste material recovery plate 401 is arranged between the abrasive belt mechanisms 5 on the upper and lower sides, and the other waste material recovery plate 401 is arranged below the abrasive belt mechanism 5 on the lower side. Function: The waste material recovery plate can on the one hand collect the waste materials generated during the grinding of the gate, and on the other hand can also prevent interference between the upper and lower groups of abrasive belt mechanisms.
[0039] Specifically, the manipulator body 1 is a six-axis manipulator. A finger cylinder is provided at the movable end of the manipulator body 1. Function: By using the motion principle of the six-axis manipulator, a standard motion trajectory can be formulated to replace the manual grinding of the gate. By adding a finger cylinder in the manipulator to horizontally grab the tooling, the cylinder can open and close horizontally to grab the product. The material conveying rack 2 is arranged on the left or right side of the manipulator body 1. Two second slide rails 201 with lengths extending left and right and a driving cylinder are provided on the material conveying rack 2. The two second slide rails 201 and the driving cylinder are distributed front and back. The driving cylinder is arranged between the two second slide rails 201. The two second slide rails 201 are respectively slidably connected to the front and rear ends of the tooling tray 202. The driving end of the driving cylinder is fixedly connected to the middle of the tooling tray 202. The tooling tray 202 is a profiling tooling made of cushion wood. During actual operation: The tooling tray is balanced by the two second slide rails, and then the driving cylinder is used to drive the tooling tray to move left and right. Since the tooling tray can position the product, it can cooperate with the manipulator to automatically pick up parts on the tooling tray. When switching products, replace the fixed tooling tray, replace the finger cylinder on the manipulator, and adjust the program. The manipulator can be used for processing by executing according to the link, and different product switching can be applied. Function: The operator only needs to randomly inspect the surface of the tooling tray / the workpiece product on the tray; the operator is isolated from the dust by a dust suction room and does not come into contact with the dust; one person can operate multiple devices to grind the gate. By using the profiling tooling made of cushion wood to position the product, since the installation position shape has good adaptability to the shape of the product, the grasping direction of the finger cylinder is accurately consistent with the product positioning.
[0040] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
