Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading machines, in particular to a self-adaptive loading and unloading machine device and a working method. Background Art

[0002] At present, the existing processing technology of metal foil products still mainly relies on manual work to complete each process. The manufacturing process is: place a metal sheet calculated according to the size of the black gold paper at the center of the black gold paper of any size, and then place a piece of black gold paper on the metal sheet, and then place another piece of metal sheet, and repeat this process. When the number of metal sheets placed reaches the set number, pack and hammer them to make the metal sheets into foil, then peel off the black gold paper, take out the metal foil, and the black gold paper can be reused.

[0003] The current equipment has the following defects:

[0004] 1. Due to the design of the mechanical structure, the working efficiency of this machine is low and it is impossible to achieve fast and continuous production.

[0005] 2. The length of the cut metal sheet cannot be adjusted and cannot be applied to various size requirements;

[0006] 3. The existing equipment has a complex and large mechanical structure, is not easy to maintain and consumes a lot of power.

[0007] An invention patent with application number CN202010191646.8 proposed a solution, namely, a loading machine consisting of an assembly mechanism, a metal sheet platform, a slicing mechanism and a metal belt. This device simplifies the structure of the loading machine, making it easier for general staff to maintain, and at the same time, it is a light-load device with reduced power consumption. However, this technology still has the following problems:

[0008] 1. This device has many moving parts, and the operations of loading black gold paper and making gold foil are too cumbersome. The equipment is prone to deviation, resulting in shutdown for correction.

[0009] 2. The placement of black gold paper and metal foil is often offset. The current equipment uses the same motor to drive the trays of two boxes to rise and fall. Since the finished product box contains both black gold paper and metal foil, and the black gold carton only takes out the black gold paper, the objects in the two boxes are not on the same level. In order for the suction nozzle to suck up the black gold paper, the black gold paper side is always controlled on the same level. However, the finished product box is loaded with black gold paper and metal foil at the same time, so the finished product in the finished product box is higher than the black gold paper in the black gold carton. This causes the black gold paper on the finished product side to be rubbed by the metal foil suction cup and deviated to the black gold carton side, and the metal foil will be rubbed by the black gold paper suction cup and deviated to the metal foil cutting machine side, which will cause the previously stacked metal foil to be misplaced, the metal foil is not in the middle of the black gold paper, and the black gold paper is not neat. When the finished product is hammered later, the black gold paper will be damaged and the quality of the gold foil will be affected.

[0010] In view of the shortcomings of the above-mentioned technology, a self-adaptive loading and unloading device and a working method are urgently needed. Summary of the invention

[0011] The technical problem to be solved by the present invention is to provide an adaptive loading machine device and a working method in view of the deficiencies of the above-mentioned prior art. The moving parts of the device are simplified and precise, which solves the problems of the offset of the black gold paper and the metal sheet not being placed in the middle of the black gold paper, greatly improves the utilization times of the black gold paper and the quality of the copper foil, and at the same time speeds up the operation speed and improves work efficiency.

[0012] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0013] An adaptive loading device is characterized by comprising a control mechanism, a feeding mechanism, an assembly mechanism and a controller arranged on a device support platform.

[0014] The equipment support platform includes a horizontal support frame and a vertical support frame.

[0015] The control mechanism comprises a rotating motor, a swing arm, a black gold paper suction cup and a metal sheet suction cup.

[0016] The feeding mechanism comprises a metal disc, a cutting machine and a conveying motor.

[0017] The assembly mechanism includes a black gold paper box, a finished product box, and a metal sheet box.

[0018] The rotating motor is fixed on the vertical support frame, and the rotating shaft of the rotating motor passes through the vertical support frame and is connected to the swing arm arranged on the other side of the vertical support frame.

[0019] The swing arm is fixed on the vertical support frame; the swing arm includes a pair of transverse swing arms and a pair of oblique swing arms; one end of the transverse swing arm is connected to the rotating shaft of the rotating motor, and the other end is hinged to the oblique swing arm; one end of the pair of oblique swing arms is connected to each other, and the other end is respectively connected to the transverse swing arm; the transverse swing arm and the oblique swing arm form a triangular stable structure.

[0020] The black gold paper suction cup and the metal sheet suction cup are connected by a fixing rod; the end of one end of the mutually connected oblique swing arm is connected and fixed to the fixing rod.

[0021] The metal coil is connected to the metal sheet box through a conveying motor; a cutting machine is also arranged between the metal coil and the metal sheet box.

[0022] The black gold paper box, finished product box and metal sheet box are arranged in sequence on a horizontal support table; the bottoms of the black gold paper box and the finished product box are respectively fixed to the equipment support platform through elastic parts.

[0023] The rotating motor, the conveying motor and the cutting machine are all connected to the controller.

[0024] As a further preferred embodiment of the present invention, the number of the black gold paper suction cups is two.

[0025] As a further preferred embodiment of the present invention, a vacuum solenoid valve is provided on the black gold paper suction cup and the metal sheet suction cup.

[0026] As a further preferred embodiment of the present invention, a black gold paper baffle is provided on the top of the black gold paper box.

[0027] As a further preferred embodiment of the present invention, a finished product baffle is provided on the top of the finished product box.

[0028] As a further preferred embodiment of the present invention, the elastic member is a compression spring.

[0029] As a further preferred embodiment of the present invention, the distances among the black gold paper box, the finished product box and the metal sheet box are equal and equal to the length of the fixing rod arranged between the black gold paper suction cup and the metal sheet suction cup.

[0030] As a further preferred embodiment of the present invention, a distance sensor is arranged between the metal coil and the cutting machine; the distance sensor is connected to the controller.

[0031] A working method of an adaptive loading device comprises the following steps:

[0032] Step 1: The conveying motor feeds the metal coil into the cutting machine according to the controller instruction to cut out the metal sheet. The size of the metal sheet is preset by the distance sensor according to the controller;

[0033] Step 2, put the black gold paper into the black gold paper box, connect the metal belt and the conveying motor; start the rotating motor, and the rotating motor drives the swing arm to move according to the control command of the controller, so as to move the black gold paper suction cup to the top of the black gold paper box; at the same time, since the black gold paper suction cup and the metal sheet suction cup are fixed by a fixing rod, and the length of the fixing rod is equal to the distance between the black gold paper box and the finished product box, the metal sheet suction cup is thus moved to the top of the finished product box at the same time;

[0034] Step 3, the vacuum solenoid valve on the black gold paper suction cup is energized to absorb the black gold paper; the vacuum solenoid valve on the metal sheet suction cup loses power to release the metal sheet; there is a black gold paper compression spring under the black gold paper box, and a black gold paper baffle above the black gold paper box; as the black gold paper is taken into the finished product box, there is less and less black gold paper in the black gold paper box, but under the action of the black gold paper compression spring, the black gold paper is always under the black gold paper baffle and kept on the same horizontal plane;

[0035] Step 4: The rotating motor transports the black gold paper sucked up by the black gold paper suction cup to the top of the finished product box according to the control instruction of the controller, and the metal sheet suction cup moves to the top of the metal sheet box;

[0036] Step 5: The vacuum solenoid valve on the black gold paper suction cup loses power, releasing the black gold paper; the vacuum solenoid valve on the metal sheet suction cup gains power, sucking the metal sheet in the metal sheet box;

[0037] Step 6, the swing arm drives the black gold paper suction cup and the metal sheet suction cup back to the initial position, and repeats the above steps; there is a finished product compression spring under the finished product box, and a finished product baffle plate above the finished product box. As the black gold paper and metal sheets are taken into the finished product box, more and more finished products are in the finished product box, but since the stroke of the metal sheet suction cup for each descent is fixed, that is, the metal sheet suction cup presses the finished product compression spring downward, the finished product is always under the finished product baffle plate and maintained on the same horizontal plane;

[0038] Step 7. When the number of stacked metal sheets reaches the set number, pack and hammer them into foil, then peel off the black gold paper and take out the metal foil. The black gold paper can be reused.

[0039] The present invention has the following beneficial effects:

[0040] 1. The present invention improves the operation control method of the control mechanism, connects and fixes the black gold paper suction cup and the finished product suction cup, and simultaneously moves the black gold paper suction cup and the finished product suction cup through the operating mechanism, thereby avoiding the relative position offset of the two suction cups; at the same time, the distance between the black gold paper box, the finished product box and the metal sheet box is set to the same length as the length of the fixed rod, thereby ensuring that the suction cup and the material box are accurately docked.

[0041] 2. The present invention arranges compression springs at the bottom of the black gold paper box and the finished product box, and uses the elastic force to make the black gold paper box and the finished product box automatically float up and move down according to the material level in the box, so that the top of the black gold paper box and the finished product box continues to dock with the suction cup to ensure the continuity of work.

[0062] The black gold paper suction cup 23 and the metal sheet suction cup 24 are connected by a fixing rod 25; the end of the oblique swing arm connected to each other is connected and fixed to the fixing rod 25; thus, the lateral swing arm 221 and the oblique swing arm 222 are connected to the black gold paper suction cup 23 and the metal sheet suction cup 24 through the fixing rod 25, and the lifting and movement of the swing arm 22 can be controlled by the rotating motor 21, thereby controlling the movement and placement of the black gold paper suction cup 23 and the metal sheet suction cup 24.

[0063] The black gold paper suction cup 23 is provided with two. The black gold paper suction cup 23 and the metal sheet suction cup 24 are provided with a vacuum solenoid valve, which is used to suck the black gold paper box metal sheet.

[0064] The metal coil 31 is connected to the metal sheet box 43 via a conveying motor 33 ; a cutting machine 32 is also arranged between the metal coil 31 and the metal sheet box 43 .

[0065] The black gold paper box 41 , the finished product box 42 and the metal sheet box 43 are arranged in sequence on the horizontal support platform 12 ; a black gold paper baffle 45 is arranged on the top of the black gold paper box 41 ; and a finished product baffle 46 is arranged on the top of the finished product box 42 .

[0066] The distances between the black gold paper box 41 , the finished product box 42 and the metal sheet box 43 are equal, and are equal to the length of the fixing rod 25 arranged between the black gold paper suction cup 23 and the metal sheet suction cup 24 .

[0067] The bottoms of the black gold paper box 41 and the finished product box 42 are respectively fixed to the equipment support platform 10 through elastic members 44. The elastic members 44 can be selected as compression springs or other elastic members that can automatically expand and contract.

[0068] A distance sensor 34 is disposed between the metal coil 31 and the cutting machine 32 ; the distance sensor 34 is connected to the controller 50 .

[0069] The rotating motor 21 , the conveying motor 33 , and the cutting machine 32 are all connected to the controller 50 , and the rotating motor 21 is controlled by the controller 50 , thereby controlling the position of the suction cup.

[0070] A working method of an adaptive loading device comprises the following steps:

[0071] Step 1: The conveying motor 33 feeds the metal coil 31 into the cutting machine 32 according to the controller instruction to cut out the metal sheet. The size of the metal sheet is preset by the distance sensor 34 according to the controller;

[0072] Step 2, put the black gold paper into the black gold paper box 41, connect the metal coil 31 and the conveying motor 33; start the rotating motor 21, and the rotating motor 21 drives the swing arm 22 to move according to the control instruction of the controller 50, and moves the black gold paper suction cup 23 to the top of the black gold paper box 41; at the same time, since the black gold paper suction cup 23 and the metal sheet suction cup 24 are fixed by the fixing rod 25, and the length of the fixing rod 25 is equal to the distance between the black gold paper box 41 and the finished product box 42, the metal sheet suction cup 24 is thus moved to the top of the finished product box 42 at the same time;

[0073] Step 3, the vacuum solenoid valve on the black gold paper suction cup 23 is energized to suck the black gold paper; the vacuum solenoid valve on the metal sheet suction cup 24 is de-energized to release the metal sheet; there is a black gold paper compression spring under the black gold paper box 41, and a black gold paper baffle 45 above the black gold paper box 41; as the black gold paper is taken into the finished product box 42, the black gold paper in the black gold paper box 41 becomes less and less, but under the action of the black gold paper compression spring, the black gold paper is always under the black gold paper baffle 45 and maintained on the same horizontal plane;

[0074] Step 4, the rotating motor 21 transports the black gold paper sucked by the black gold paper suction cup 23 to the top of the finished product box 42 according to the control instruction of the controller 50, and the metal sheet suction cup 24 moves to the top of the metal sheet box 43;

[0075] Step 5: The vacuum solenoid valve on the black gold paper suction cup 23 loses power, releasing the black gold paper; the vacuum solenoid valve on the metal sheet suction cup 24 gains power, sucking the metal sheet in the metal sheet box 43;

[0076] Step 6, the swing arm 22 drives the black gold paper suction cup 23 and the metal sheet suction cup 24 back to the initial position, and repeats the above steps; there is a finished product compression spring under the finished product box 42, and a finished product baffle 46 above the finished product box 42. As the black gold paper and metal sheets are taken into the finished product box 42, more and more finished products are in the finished product box 42, but since the stroke of the metal sheet suction cup 24 falling each time is fixed, that is, the metal sheet suction cup 24 presses the finished product compression spring downward, so that the finished product is always under the finished product baffle 46 and maintained on the same horizontal plane;

[0077] Step 7. When the number of stacked metal sheets reaches the set number, pack and hammer them into foil, then peel off the black gold paper and take out the metal foil. The black gold paper can be reused.

[0078] The working principle and method of this device are:

[0079] The conveying motor 33 conveys the metal coil 31 to the cutting machine 32 according to the controller instruction to cut out the metal sheet. The size of the metal sheet is preset by the distance sensor 34 according to the controller.

[0080] Put the black gold paper into the black gold paper box 41, and connect the metal coil 31 and the conveying motor 33. Start the rotating motor 21, which drives the swing arm 22 to move according to the control instruction of the controller 50, and moves the black gold paper suction cup 23 to the top of the black gold paper box 41. At the same time, since the black gold paper suction cup 23 and the metal sheet suction cup 24 are fixed by the fixing rod 25, and the length of the fixing rod 25 is equal to the distance between the black gold paper box 41 and the finished product box 42, the metal sheet suction cup 24 moves to the top of the finished product box 42 at the same time.

[0081] The vacuum solenoid valve on the black gold paper suction cup 23 is energized to absorb the black gold paper; the vacuum solenoid valve on the metal sheet suction cup 24 is de-energized to release the metal sheet.

[0082] The rotating motor 21 transports the black gold paper sucked up by the black gold paper suction cup 23 to above the finished product box 42 according to the control instruction of the controller 50, and the metal sheet suction cup 24 moves to above the metal sheet box 43 at the same time.

[0083] The vacuum solenoid valve on the black gold paper sucker 23 loses power, releasing the black gold paper; the vacuum solenoid valve on the metal sheet sucker 24 is energized, sucking the metal sheet in the metal sheet box 43. The swing arm 22 drives the black gold paper sucker 23 and the metal sheet sucker 24 back to the initial position, and repeats the above steps.

[0084] There is a black gold paper compression spring below the black gold paper box 41, and a black gold paper baffle 45 above the black gold paper box 41. As the black gold paper is taken into the finished product box 42, there is less and less black gold paper in the black gold paper box 41, but under the action of the black gold paper compression spring, the black gold paper is always below the black gold paper baffle 45 and remains on the same horizontal plane.

[0085] There is a finished product compression spring under the finished product box 42, and a finished product baffle 46 above the finished product box 42. As the black gold paper and metal sheets are taken into the finished product box 42, more and more finished products are in the finished product box 42. However, since the stroke of the metal sheet suction cup 24 for each descent is fixed, that is, the metal sheet suction cup 24 presses the finished product compression spring downward, the finished product is always below the finished product baffle 46 and maintained on the same horizontal plane.

[0086] The present invention improves the operation control method of the control mechanism, connects and fixes the black gold paper suction cup and the finished product suction cup, and simultaneously moves the black gold paper suction cup and the finished product suction cup through the operating mechanism, thereby avoiding the relative position offset of the two suction cups; at the same time, the distance between the black gold paper box, the finished product box and the metal sheet box is set to the same length as the length of the fixed rod, thereby ensuring that the suction cup and the material box are accurately docked.

[0087] When the number of stacked metal sheets reaches the set number, they are packaged and hammered to make the metal sheets into foil. Then the black gold paper is peeled off and the metal foil is taken out. The black gold paper can be reused.

[0088] The preferred embodiments of the present invention are described in detail above; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
