Description

Technical Field

[0001] This invention belongs to the technical field of eyeglass manufacturing equipment, and relates to a stamping device, particularly an automatic stamping device for eyeglass temples. Background Technology

[0002] Eyeglasses consist of lenses, frames, temples, a bridge, nose posts, and nose pads, with temples at both ends of the frame for securing them. In current manufacturing processes, temples are typically hand-held by a person while a machine cuts or stamps them. However, these cutting and stamping operations are usually performed in steps: first, the temples are stamped, then the stamped temples are collected, stored, and transported before the scrap edges are cut off. This method requires significant manual labor, resulting in low production efficiency and making it impossible to complete the stamping, cutting, and forming of the temple ends in a single process. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a highly automated automatic stamping device for mirror temples.

[0004] The objective of this invention can be achieved through the following technical solution: An automatic stamping device for eyeglass temples includes a punch press, a table plate mounted on the punch press, a mounting top plate at the bottom of the die-casting head of the punch press, and a feeding mechanism, a length positioning mechanism, a first stamping mechanism, a second stamping mechanism, a waste edge cutting mechanism, a blanking mechanism, and a feeding mechanism provided between the table plate and the mounting top plate. The feeding mechanism is located at one end of the feeding mechanism, and a plurality of eyeglass temples are placed on the feeding mechanism. The feeding mechanism feeds the eyeglass temples onto the feeding mechanism, and the feeding mechanism moves the eyeglass temples to the length positioning mechanism. The length positioning mechanism positions the placement of the eyeglass temples, and the feeding mechanism then moves the eyeglass temples to the first stamping mechanism, the second stamping mechanism, and the waste edge cutting mechanism to form the eyeglass temples. The blanking mechanism blanks the formed eyeglass temples.

[0005] In the aforementioned automatic temple stamping equipment, the feeding mechanism is a first feeding mechanism, which includes an ejector cylinder, a feeding belt, a feeding motor, and a feeding step. The feeding step is inclined, and the ejector cylinder drives the temple to move onto the feeding step. The feeding belt is also inclined and contacts the feeding step. The feeding motor drives the feeding belt to move, and the feeding belt has several evenly distributed feeding grooves. During the movement of the feeding belt, the temple on the feeding step will be inserted into the feeding grooves.

[0006] The aforementioned automatic temple stamping equipment also includes several receiving blocks. Each receiving block has a receiving groove, and the side of the receiving block extends upward to form a receiving baffle. When the feeding belt drives the temple to move, the temple detaches from the feeding belt due to downward gravity and moves into the receiving groove.

[0007] The aforementioned automatic stamping equipment for mirror temples also includes a feeding base fixed to the end of the table. The feeding base is equipped with an inclined first storage plate and a second storage plate. A feeding block is provided between the first storage plate and the second storage plate. The top surface of the feeding block and the second storage plate form the feeding step. Several mirror temples waiting to be fed are stacked on the first storage plate. Several ejection cylinders are provided and installed at the bottom of the first storage plate. Several ejection holes are formed on the first storage plate. When the piston rod of the ejection cylinder is ejected, it exposes the ejection hole and contacts the mirror temple on the first storage plate. The ejection cylinder drives several mirror temples to move upward synchronously. During the upward movement, the mirror temples roll down onto the feeding step.

[0008] In the aforementioned automatic stamping equipment for mirror temples, a first feeding rotating shaft and a second feeding rotating shaft are installed on the feeding base.

[0041] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0042] like Figure 1-7 As shown, the automatic temple stamping equipment includes a punch press 10, a table 11 mounted on the punch press 10, and a mounting top plate at the bottom of the die-casting head of the punch press 10. Between the table 11 and the mounting top plate are a feeding mechanism, a length positioning mechanism 2, a first stamping mechanism 3, a second stamping mechanism 4, a scrap edge cutting mechanism 5, a unloading mechanism 6, and a feeding mechanism 7. The feeding mechanism is located at one end of the feeding mechanism 7, and several temples are placed on the feeding mechanism. The feeding mechanism 1 feeds the temples to the feeding mechanism 7. The feeding mechanism 7 moves the temples to the length positioning mechanism 2. The length positioning mechanism 2 positions the temples. The feeding mechanism 7 then moves the temples to the first stamping mechanism 3, the second stamping mechanism 4, and the scrap edge cutting mechanism 5 to form the temples. Finally, the unloading mechanism 6 unloads the formed temples.

[0043] First embodiment: The feeding mechanism is a first feeding mechanism 1, which includes an ejector cylinder 101, a feeding belt 102, a feeding motor, and a feeding base 104 fixed to the end of the platform 11. An inclined first storage plate 105 and a second storage plate 106 are mounted on the feeding base 104. A feeding block 107 is provided between the first and second storage plates 105 and 106. A feeding step 108 is formed between the top surface of the feeding block 107 and the second storage plate 106, and the feeding step 108 is inclined. Several temples awaiting feeding are stacked on the first storage plate 105, and due to the inclined arrangement of the first storage plate 105, the temples are located at the end of the first storage plate 105 and contact the side of the feeding block 107. Several ejector cylinders 101 are provided and installed at the bottom of the first storage plate 105. The first storage plate 105 has several ejection holes. When the piston rod of the ejector cylinder 101 ejects, it protrudes from the ejection hole and contacts the temple on the first storage plate 105. The ejector cylinder 101 drives several temples to move upward synchronously. During the upward movement, the temples roll onto the loading step 108. Due to the inclined setting of the loading step 108, the temples move to the end of the loading step 108 that contacts the second storage plate 107. In this embodiment, three sets of ejector cylinders 101 are provided to make the ejection of each part of the temple more uniform and ensure the stability of the temple ejection.

[0044] In the above technical solution: a first feeding rotating shaft and a second feeding rotating shaft are installed on the feeding base 104. Several synchronous pulleys are fitted onto the first feeding rotating shaft, with shims between adjacent synchronous pulleys. A rotating shaft cylinder is fitted onto the second feeding rotating shaft. Several feeding belts 102 are provided, with both ends of the feeding belts 102 respectively fitted onto the synchronous pulleys and the rotating shaft cylinders. The feeding belts 102 are inclined. A planetary reducer 110 is also provided on the feeding base 104. The feeding motor drives the first feeding rotating shaft to rotate through the planetary reducer, thereby driving the feeding belts 102 to move. Several evenly distributed feeding grooves 117 are formed on the feeding belts 102. During the movement of the feeding belts 102, the temples on the feeding steps 108 will be inserted into the feeding grooves 117. Only one temple can be accommodated in each feeding groove 117.

[0045] In the above technical solution: an arc-shaped connecting plate 111 is installed at the end of the second storage plate 106, and an inclined receiving plate 112 is installed at the end of the connecting plate 111. The receiving plate 112 has a receiving notch 113 and two mounting grooves 114 at its end, with the two mounting grooves 114 located on both sides of the receiving notch 113. Several receiving blocks 115 are installed in the mounting grooves 114, and each receiving block 115 has a receiving groove. The side of the receiving block 115 extends upward to form a receiving baffle 116. A feeding belt 102 is also fitted onto the second storage plate 106 and the connecting plate 111, with part of the feeding belt 102 located on the second storage plate 106 and the connecting plate 111, and the inclination angle of the feeding belt 102 is the same as the inclination angle of the second storage plate 106. A belt groove is formed on the connecting plate 111 for the feeding belt 102 to pass through.

[0046] In the above technical solution: the feeding base 104 is also equipped with a feeding motor and a feeding brush roller 103. A feeding bracket 118 is installed on the side of the feeding base 104. Both the feeding motor and the feeding brush roller 103 are mounted on the feeding bracket 118. The feeding motor drives the feeding brush roller 103 to rotate. A detection sensor 109 is also installed on the feeding bracket 118. When the detection sensor 109 senses that the feeding belt 102 is moving, the detection sensor 109 transmits a signal to make the feeding motor run. The feeding motor drives the feeding brush roller 103 to rotate. Since the feeding groove 117 can only accommodate one temple, the excess temple in the feeding groove 117 will protrude from the feeding belt 102. When the feeding brush roller 103 rotates, it can brush down the excess temple in the feeding groove 117, ensuring that there is only one temple in the feeding groove 117 and preventing overloading. When the detection sensor 109 senses that the feeding belt 102 has stopped moving, the detection sensor 109 transmits a signal to stop the feeding motor.

[0047] During loading, the ejector cylinder 101 first moves the temples on the first storage plate 105 upwards, causing them to move into the loading trough 117 on the feeding belt 102. Specifically, when the piston rod of the ejector cylinder 101 ejects, it exposes the ejector hole and contacts the temples on the first storage plate 105. The ejector cylinder 101 then moves several temples upwards synchronously. During this upward movement, the temples roll onto the loading step 108. Due to the inclined design of the loading step 108, the temples move to the end of the loading step 108 that contacts the feeding belt 102. As the feeding belt 102 moves, the temples on the loading step 108 are engaged in the loading trough 117, and the feeding belt 102 moves the temples synchronously. As the temple moves with the feeding belt 102, the detection sensor 109 transmits a signal to make the feeding motor run. The feeding motor drives the feeding brush roller 103 to rotate. The feeding brush roller 103 brushes down the excess temple in the feeding trough 117, ensuring that there is only one temple in the feeding trough 117, and preventing the overloading of the temple.

[0048] Next, the feeding belt 102 moves the temple upwards onto the connecting plate 111. As the feeding belt 102 continues to move the temple, the temple detaches from the feeding belt 102 due to downward gravity. The temple moves along the inclined receiving plate 112 into the receiving groove on the receiving stop 115. The receiving stop 116 prevents the temple from falling off the receiving plate 112. The temple in the receiving groove awaits feeding from the feeding mechanism 7. At this time, the feeding belt 102 stops moving. Only after the temple in the receiving groove is removed by the feeding mechanism 7 does the feeding belt 102 begin to move and pull the next temple into the receiving groove. This prevents more than one temple from existing in the receiving groove, thus preventing overloading and affecting subsequent steps.

[0049] In the above technical solution: the feeding mechanism 7 includes several feeding grippers 71, a lifting cylinder, and a transverse cylinder. The lifting cylinder is fixed on the platform 11, and its piston rod extends vertically upward and is fixedly connected to a vertical plate. The several feeding grippers 71 are fixed on a movable frame, which is located on a track on the vertical plate. A transverse cylinder is fixedly connected to the vertical plate, and its piston rod extends horizontally and connects to the movable frame. The transverse cylinder can drive the movable frame to move horizontally relative to the vertical plate. The lifting cylinder and the transverse cylinder respectively drive the feeding grippers 71 to move vertically and horizontally. The several feeding grippers 71 are sequentially designated as a first feeding gripper, a second feeding gripper, a third feeding gripper, a fourth feeding gripper, a fifth feeding gripper, a sixth feeding gripper, etc., and the number of feeding grippers 71 is the same as the number of mechanisms that need to feed or receive materials.

[0050] The above technical solution also includes several positioning grippers 72, including a first positioning gripper, a second positioning gripper, a third positioning gripper, a fourth positioning gripper, etc. The first positioning gripper is used to grip the temple of the mirror that is fed to the length positioning mechanism 2, the second positioning gripper is used to grip the temple of the mirror that is fed to the first stamping mechanism 3, the third positioning gripper is used to grip the temple of the mirror that is fed to the second stamping mechanism 4, and the fourth positioning gripper is used to grip the temple of the mirror that is fed to the waste edge cutting mechanism 5.

[0051] The feeding process of the feeding mechanism 7 is as follows: The lifting cylinder drives the feeding gripper 71 to move down, so that the feeding gripper 71 is below the temple. The lateral movement cylinder drives the feeding gripper 71 to move towards the loading mechanism 1. The first feeding gripper enters the receiving notch 113. At this time, the lifting cylinder drives the feeding gripper 71 to move up, so that the first feeding gripper can grab the temple in the receiving groove. Then the lifting cylinder continues to drive the feeding gripper 71 to move up, so that the temple is separated from the receiving groove and is above the receiving baffle 116. The lateral movement cylinder drives the first feeding gripper to move to the length positioning mechanism 2. The lifting cylinder drives the feeding gripper 71 to move down, so that the temple is placed on the length positioning mechanism 2. Then the first positioning gripper grabs the temple and positions the temple on the length positioning mechanism 2. The first feeding gripper releases the temple. At this time, the feeding mechanism 7 completes the process of transporting the temple from the loading mechanism 1 to the length positioning mechanism 2. Repeating the above steps, the second feeding gripper picks up the temple that has been positioned on the length positioning mechanism 2 and moves it to the first stamping mechanism 3. At the same time, the first feeding gripper continues to pick up the temple on the loading mechanism 1 and move it to the length positioning mechanism 2. By continuously repeating the above steps, the feeding mechanism completes the product transfer between each station.

Figure 6 , 7 As shown, the second feeding mechanism 14 includes a third storage plate 141, a lifting cylinder 143, a feeding bracket 144, several receiving steps 142, and several lifting plates 145. The feeding bracket 144 is fixed on the platform 11, the receiving steps 142 are installed on the side of the feeding bracket 144, the third storage plate 141 is inclined at the bottom of the receiving steps 142, and several temples are stacked on the third storage plate 141. The lifting plate 145 is also provided with lifting steps 146 of the same number as the receiving step 142. The end of the third storage plate 141 is provided with several first lifting holes 1416, and the receiving step 142 is provided with several second lifting holes 1417. The lifting plate 145 is located below the receiving step 142 and is staggered from it, so that the lowest lifting step 146 of the lifting plate 145 is located below the third storage plate 141 and corresponds to the first lifting holes 1416. The other lifting steps 146 on the lifting plate 145 are located below the receiving step 142 and correspond to the second lifting holes 1417. The end of the lifting step 146 is located near the upward-extending side of the lifting step 146, and the end of the lifting step 146 is also provided with a lifting protrusion 147. Both the receiving step 142 and the lifting step 146 are inclined. Several lifting plates 145 are fixedly connected to each other by connecting rods, and the piston rod of the lifting cylinder 143 is connected to the connecting rods. The lifting cylinder 143 drives the connecting rods and lifting plates 145 to move upward. The lifting step 146 passes through the first lifting hole 1416 and the second lifting hole 1417. The lifting step 146 drives the temple on the third storage plate 141 to move upward to the first receiving step 142. Due to gravity and the guide of the inclined lifting step 146 and receiving step 142, the temple rolls down to the end of the receiving step 142. The temple is fed from the third storage plate 141 to the first receiving step 142. The above steps are repeated to move the temple to the last receiving step 142.

[0067] In the above technical solution, the second feeding mechanism 14 further includes a rotary motor 148 and a turntable 149. The rotary motor 148 is fixed to the side of the feeding bracket 144, and a rotating shaft is connected to the output shaft of the rotary motor 148.

Several feeding grooves 1410 are formed on the feeding annular block 1411, and only one temple can be placed in each feeding groove 1410. The feeding annular block 1411 contacts the last receiving step 142 to prevent the temple on the last receiving step 142 from falling off.

[0068] In the above technical solution: the second feeding mechanism 14 also includes a mounting crossbar 1412 installed on the feeding bracket 144 and a receiving guide block 1413 located on the mounting crossbar 1412. The receiving guide block 1413 is provided with a guide slope 1414 and a receiving groove 1415. The guide slope 1414 extends from the side of the feeding ring block 1411 to the receiving groove 1415.

[0069] The rotary motor 148 drives the turntable 149 and the feeding ring block 1411 to rotate. When the feeding groove 1410 on the feeding ring block 1411 is at the same height as the last receiving step 142, the temple on the last receiving step 142 rolls into the feeding groove 1410. The feeding ring block 1411 drives the temple to rotate. When the temple comes into contact with the guide slope 1414, the temple is removed from the feeding groove 1410 due to gravity and rolls into the receiving groove 1415 under the guidance of the guide slope 1414, thus completing the feeding of the temple.

[0070] This automatic temple stamping equipment can automatically complete the feeding, initial stamping, stamping forming, waste edge cutting, and unloading of eyeglass temples in one go. It boasts a high degree of automation, meeting the automated production needs of enterprises, reducing manual intervention, and greatly improving production efficiency. The first feeding mechanism 1 transfers the temples on the feeding step 108 to the receiving groove via the feeding belt 102, and uses a rotating brush roller 103 to brush off excess temples from the feeding trough 117, ensuring that only one temple is in the feeding trough 117 and preventing overloading. The second feeding mechanism 14... The lifting step 146 and the feeding groove 1410 on the feeding ring block 1411 transfer the temple to the receiving groove 1415. The structure is ingenious and simple, ensuring stable feeding. A length positioning mechanism 2 is set in front of the first stamping mechanism 3 to ensure that the length and position of the temple are consistent during feeding, and to ensure that the subsequent stamping on the temple is consistent, thus ensuring the aesthetics and production consistency of the temple. According to production needs, an annealing mechanism 8, a tail needle stamping mechanism 9, a head and tail cutting mechanism 12, and a tip mechanism 13 can also be set to meet the production needs of various types of temples, with a wide range of applications and more flexible use.
