Description

Technical Field

[0001] The invention relates to the technical field of door and window processing equipment, and in particular to an automatic feeding device for fixing sheets used in automatic screw fastening machines. Background Art

[0002] Automatic screw fastening machine (also called nailing machine) is the main equipment for fastening the fixing plate to the door and window profiles by screws. Figure 5 As shown, it includes a frame, two translation mechanisms are provided on the frame, support arms are provided on the two translation mechanisms, vertical plates are provided on the support arms, guide rails are provided vertically on the vertical plates, motor plates and chuck plates are provided on the guide rails, guide columns are provided between the motor plates and the chuck plates, reset springs are provided on the guide columns, motors for tightening screws are provided on the motor plates, chucks for clamping screws are provided on the chuck plates, and the chucks are directly connected to the automatic screw-on mechanism. The fixing plate (also called connecting plate or mounting plate or connecting piece) mainly plays the role of fixing doors and windows on the wall, such as Figure 7-8 As shown, the fixing plate is provided with nail holes, and the existing automatic screw fastening machine can realize automatic screw feeding, automatic fixing plate feeding and automatic screw fastening, which significantly improves the installation efficiency of the fixing plate.

[0003] In the past, research on automatic screw fastening machines mainly focused on how to realize automatic screw feeding and automatic screw fastening, while there was less research on the automatic loading of fixed plates. Although the existing automatic screw fastening machines can also realize the loading of fixed plates, there are still some problems. In the prior art, the fixed plates are mainly fed by the structure of lateral feeding (feeding along the length direction of the fixed plate). This feeding method can only feed straight fixed plates, but cannot realize feeding of curved fixed plates, or realize feeding of curved fixed plates by adding multiple kinematic pairs on the basis of lateral feeding (the structure is very complicated); the use of lateral feeding causes the lateral length of the entire structure to be too long, which is very inconvenient to use and the structure is not compact enough; the lateral feeding distance is long, the push plate is long, and it is easy to deform after long-term use, which eventually leads to jamming and even the problem of fixed plate popping out. Our company has solved the above problems and applied for relevant patents. The patent name is: material box and automatic feeding device, application number: 202022064092.3. For specific solutions, please refer to the specific content of the patent.

[0004] However, in the process of practical application, it was found that there are other deep-seated technical problems that need to be solved urgently. One of the more prominent problems is that most fixed plates have burrs on the edges. These burrs are very hard and sharp, which causes the fixed plate to be blocked at the discharge port. In severe cases, it causes the discharge to be stuck, or even the fixed plate cannot be pushed out longitudinally. Since fixed plates are generally processed by stamping or cutting, it is easy to produce burrs (burrs) on the edges of the fixed plates. In addition, since fixed plates belong to the low-end industry and there are no industry standards for burrs, most fixed plates are directly produced and sold without processing the burrs. Therefore, it is necessary to develop a new fixed plate feeding device that can not only solve the technical problems caused by the burrs, but also ensure efficient and accurate feeding.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0030] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0032] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0033] In the present invention, the terms "front", "rear", "left", "right", "A", "B", "vertical", and "longitudinal" are used for descriptive purposes only and shall not be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "provided with", "set", "connected", "connected" and the like should be understood in a broad sense. For example, "provided with" and "set" can be fixedly installed, detachably installed, or integrated; "connected" can be directly connected or connected through an intermediate medium. "Connected" in this application mainly refers to gas path communication. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, it should be noted that the "vertical plate" and the "chuck plate" are existing components in the existing automatic screw fastening machine, and this part belongs to common knowledge.

[0036] like Figure 1-5 As shown, the automatic feeding device for fixing sheets of an automatic screw fastening machine comprises:

[0037] The material box 1 is used to vertically place the fixing plate 2, the fixing plate 2 is a straight fixing plate 201 or a curved fixing plate 202, the material box 1 is connected to the vertical plate 3, and the upper end of the material box 1 is provided with an opening 111 for the fixing plate 2 to enter and exit;

[0038] Two translation feeding mechanisms 4 are used for cooperating with the material box 1 for feeding. The two translation feeding mechanisms 4 are arranged on the chuck plate 5. The ends of the two translation feeding mechanisms 4 are provided with a magnetic seat 6 for adsorbing the fixed sheet 2. The two translation feeding mechanisms 4 realize longitudinal movement and vertical movement. The vertical movement is used to vertically extract the fixed sheet 2 from the material box 1, and the longitudinal movement is used to send the extracted fixed sheet 2 to the bottom of the chuck 7, and the nailing hole 203 on the fixed sheet 2 is vertically aligned with the chuck 7. By setting the material box 1 on the vertical plate 3, and the nailing hole 203 on the fixed sheet 2 in the material box 1 is longitudinally aligned with the chuck 7, and the chuck plate 5 is used as the installation reference, the two translation mechanisms can be used to realize the precise and efficient vertical material taking and longitudinal feeding feeding method, the material taking is no longer affected by burrs, and the longitudinal feeding is still adopted. The overall structural design is simple and compact, and the feeding is efficient and precise.

[0039] The nailing holes 203 on the fixing plate 2 in the material box 1 are longitudinally aligned with the clamp 7. The longitudinal alignment of the nailing holes 203 and the clamp 7 can reduce the drive, thereby realizing that only two translations are required to accurately transport the fixing plate 2 to the bottom of the clamp 7.

[0040] The material box 1 is connected to the vertical plate 3 via a U-shaped frame 8. The U-shaped frame connection not only ensures a firm and reliable structure, but also avoids various components on the machine head.

[0041] The material box 1 includes a bottom plate 101, on which a front plate 102 and a rear plate 103 are spaced apart along the width direction of the fixing plate 2, and a left plate 104 and a right plate 105 are spaced apart along the length direction of the fixing plate 2, and the distance between the left plate 104 and the right plate 105 is adjustable.

[0042] The front plate 102 is provided with a left adjustment hole 106 and a right adjustment hole 108, the left plate 104 is arranged between the front plate 102 and the rear plate 103 and can be adjusted left and right, the left plate 104 is provided with a left fastening bolt 107, and the left fastening bolt 107 is arranged in the left adjustment hole 106, the right plate 105 is arranged between the front plate 102 and the rear plate 103 and can be adjusted left and right, the right plate 105 is provided with a right fastening bolt 109, and the right fastening bolt 109 is arranged in the right adjustment hole 108. By designing the material box 1 into a structural form in which the left plate 104 and the right plate 105 can be adjusted left and right, it can ensure that the nailing hole 203 of the fixing plate 2 is longitudinally aligned with the clamping head 7, and it is suitable for various fixing plates 2.

[0043] The bottom plate 101 is provided with a hollow 110, and the bending section of the bent fixing sheet 202 is arranged at the hollow 110 to achieve horizontal placement of the bent fixing sheet 202. By designing the hollow 110 on the bottom plate 101 of the material box 1, the tilt problem caused by the bent fixing sheet 202 can be solved, so that the bent fixing sheet 202 can also be arranged horizontally, which is convenient for the magnetic base 6 to adsorb, and the material is taken more accurately and quickly.

[0044] The two translation feeding mechanisms 4 include a cylinder seat A401 disposed on a chuck plate 5, a cylinder A402 is longitudinally disposed on the cylinder seat A401, a cylinder seat B403 is disposed on the piston rod of the cylinder A402, a cylinder B404 is vertically disposed on the cylinder seat B403, a material picking rod 405 is disposed on the piston rod of the cylinder B404, and the magnetic seat 6 is disposed at the end of the material picking rod 405. The cylinder drive is adopted to realize the serial drive of two translations, and the structure is simple and reliable.

[0045] The material taking rod 405 is configured in an L-shaped structure so that the material taking rod 405 can go deep into the material box 1 to take materials, making the material taking more convenient and quick.

[0046] A longitudinal guide mechanism 9 is provided between the cylinder seat B403 and the chuck plate 5, and the longitudinal guide mechanism 9 includes a longitudinal slider 901 longitudinally arranged on one side of the chuck plate 5 and a longitudinal guide rail 902 longitudinally arranged on the cylinder seat B403, and the longitudinal guide rail 902 is arranged on the longitudinal slider 901. A vertical guide mechanism 10 is provided between the material picking rod 405 and the cylinder seat B403, and the vertical guide mechanism 10 includes a vertical slider 1001 vertically arranged on one side of the cylinder seat B403 and a vertical guide rail 1002 vertically arranged on the material picking rod 405, and the vertical guide rail 1002 is arranged in the vertical slider 1001. Designing the longitudinal guide mechanism 9 and the vertical guide mechanism 10 in the two translation feeding mechanisms 4 further improves the accuracy of the movement and ensures accurate and reliable feeding.

[0047] The cylinder B404 is connected to the cylinder seat B403 through a buffer mechanism 11, and the buffer mechanism 11 includes a buffer guide rail 1101 arranged on the cylinder seat B403, and the cylinder B404 is arranged on the buffer guide rail 1101 through a buffer slider 1102. A buffer spring 1103 is arranged between the cylinder B404 and the cylinder seat B403, and a limit plate 1104 is arranged on the cylinder seat B403 to vertically limit the cylinder B404. By designing the buffer mechanism 11, the reverse force caused by the cylinder B404 when taking materials can be effectively reduced, and the service life of the cylinder B404 can be extended.

[0048] The working process of the automatic feeding device for fixed sheets of the present invention is as follows:

[0049] When working, first place the fixing plate 2 in the material box 1, and adjust the position of the fixing plate 2 through the left plate 104 and the right plate 105, so that the nailing hole 203 on the fixing plate 2 is aligned with the clamp 7 in the longitudinal direction. When nailing, the cylinder B404 is activated first, and the cylinder B404 drives the material taking rod 405 and the magnetic seat 6 on it to move downward. When the magnetic seat 6 contacts the fixing plate 2 at the top of the material box 1, the fixing plate 2 is adsorbed on the magnetic seat 6. At the same time, due to the action of the fixing plate 2, the cylinder B404 (the stroke of the cylinder B must be greater than or equal to the depth of the material box, and the stroke of the cylinder B can be designed by time, generally set at about 0.5S) will no longer continue to move downward. At this time, the fixing plate 2 will give the cylinder B404 an upward reaction force (this force is small, generally the cylinder B 404 can withstand, and it is better to add a buffer mechanism 11 to reduce the impact), the cylinder B404 resets after the downward movement is completed, and the magnetic seat 6 extracts the fixed plate 2, and then the cylinder A402 moves, and the cylinder seat B403 and the cylinder B404, the material taking rod 405, the magnetic seat 6 and the fixed plate 2 are driven to move longitudinally together until the fixed plate 2 is transported to the bottom of the chuck 7, at this time, the nail hole 203 on the fixed plate 2 is vertically aligned with the chuck 7, and then the automatic screw fastening machine fastens the fixed plate 2 to the door and window profile with screws. According to the above actions, efficient and accurate cyclic feeding of the fixed plate 2 can be achieved.

[0050] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0051] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
