Description

Technical Field

[0001] This invention relates to the field of electromechanical technology, and in particular to a clamping mechanism. Background Technology

[0002] Common pallet opening and clamping mechanisms mainly consist of a positioning and clamping platform and an ejector pin opening and clamping mechanism. They are generally used in the process of automatically loading and unloading pallet components. The mechanism requires the extension and retraction of a cylinder to change the state of the ejector pin mechanism on the opening and clamping platform, thereby opening and closing the clamping bars around the pallet components and achieving the purpose of loading and unloading the components.

[0003] The existing technology has the following drawbacks:

[0004] Currently, most clamping mechanisms on the market require a positioning clamping platform and a positioning pallet. However, the design of the positioning clamping platform is relatively cumbersome, reducing the utilization rate of the machine's internal space. The complex mechanical structure can increase the error rate of the mechanism and affect the machine's production efficiency. At the same time, common clamping mechanisms are only suitable for ordinary pallets, and may touch the workpiece being produced during the clamping process, causing unnecessary contamination of the workpiece and reducing the yield rate of the workpiece. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides an opening and closing mechanism, comprising a pallet-tapping group, a pallet-supporting group, an opening and closing group, a barcode reader group, and a control mechanism. The pallet-tapping group, the pallet-supporting group, the opening and closing group, and the barcode reader group are respectively connected to the control mechanism. The control mechanism controls the movement of the pallet-tapping group, the pallet-supporting group, and the opening and closing group. The control mechanism also controls the barcode reader group to read and input pallet information. The pallet-tapping group is used to tap the pallet to the correct position, the pallet-supporting group is used to support the pallet, the opening and closing group is used to open the clamps on the pallet, and the barcode reader group is used to read the pallet information and input the read information into the machine.

[0006] As a further improvement of the present invention, the clamping mechanism further includes a left support and a right support, the left support and the right support being used to support the tray assembly, the pallet assembly, the clamping assembly and the barcode reader assembly.

[0007] As a further improvement of the present invention, the paddle tray assembly includes a paddle block, a first support plate, and a first cylinder. The paddle block is mounted on one end of the first support plate, and the other end of the first support plate is connected to the first cylinder. The first cylinder drives the first support plate to extend or retract through telescopic movement, thereby driving the paddle block to extend or retract.

[0008] As a further improvement of the present invention, the pallet assembly includes a second pallet and a second cylinder. A second support block is installed at one end of the second pallet, and the other end of the second pallet is connected to the second cylinder. The second cylinder drives the second pallet to extend or retract through telescopic movement, thereby driving the second support block to extend or retract.

[0009] As a further improvement of the present invention, the clamping assembly includes a third cylinder, a mounting block, a mounting base, a connecting plate, and a clamping arm. The clamping arm is movably connected to one end of the mounting block, and the other end of the mounting block is fixedly connected to the third cylinder. One end of the connecting plate is movably connected to the clamping arm, and the other end of the connecting plate is movably connected to the mounting base. The mounting base is fixedly mounted on the third cylinder. When the third cylinder extends or retracts the mounting block through its telescopic movement, it also drives the clamping arm to rotate clockwise or counterclockwise.

[0010] As a further improvement of the present invention, when the third cylinder extends, it drives the mounting block to extend forward, and the mounting block drives the opening clamp arm to move clockwise. When the third cylinder retracts, it drives the mounting block to retract backward, and the mounting block drives the opening clamp arm to move counterclockwise.

[0011] As a further improvement of the present invention, the barcode reader assembly includes a mounting frame and a barcode reader, wherein the barcode reader is mounted on the mounting frame.

[0012] As a further improvement of the present invention, the clamping mechanism also includes a through-beam sensor and a diffuse reflection sensor. The through-beam sensor is used to detect whether there is a plate in the tray, and the diffuse reflection sensor detects whether the tray has reached the designated position.

[0013] As a further improvement of the present invention, the number of each of the paddle tray group, the support tray group, and the clamping group is four. The left bracket and the right bracket are each equipped with two paddle tray groups, two support tray groups, and two clamping groups. The paddle blocks of the paddle tray groups on each bracket correspond to each other. The support tray group and the clamping group on the left bracket correspond to the support tray group and the clamping group on the right bracket.

[0020] Figure 6 This is a structural diagram of the code reader group of the present invention. Detailed Implementation

[0021] like Figure 1-2 As shown, the present invention discloses an opening clamping mechanism, which includes a tray-holding group 90, a tray-supporting group 91, an opening clamping group 92, a code reader group 95, and a control mechanism 1. The tray is clamped by the cooperation between the mechanisms and the tray is entered into the machine.

[0022] The pallet-tapping assembly 90, pallet-supporting assembly 91, clamp-opening assembly 92, and barcode reader assembly 95 are respectively connected to the control mechanism 1. The control mechanism 1 controls the movement of the pallet-tapping assembly 90, pallet-supporting assembly 91, and clamp-opening assembly 92, and controls the barcode reader assembly 95 to read and input pallet information. The pallet-tapping assembly 90 is used to tap the pallet, the pallet-supporting assembly 91 is used to support the pallet, the clamp-opening assembly 92 is used to open the clamps on the pallet, and the barcode reader assembly 95 is used to read the pallet information and input the read information into the machine. The control mechanism 1 is a PLC or a microcontroller.

[0023] The clamping mechanism also includes a left support and a right support, which are used to support the tray assembly 90, the pallet assembly 91, the clamping assembly 92, and the barcode reader assembly 95.

[0024] A tray assembly 90 is installed at each end of the left and right supports, and the tray assembly 90 and the support tray assembly 91 jointly position the tray.

[0025] like Figure 3 As shown, the slapping tray assembly 90 includes a slapping block 901, a first support plate 902, and a first cylinder 903. The slapping block 901 is mounted on one end of the first support plate 902, and the other end of the first support plate 902 is connected to the first cylinder 903. The first cylinder 903 drives the first support plate 902 to extend or retract through telescopic movement, thereby driving the slapping block 901 to extend or retract. When the first cylinder 903 pushes the first support plate 902 to extend, it drives the L-shaped slapping block 901 at the end of the first support plate 902 to extend. When the first cylinder 903 retracts, it pulls the first support plate 902 to retract, and the slapping block 901 also retracts.

[0026] like Figure 4As shown, the pallet assembly 91 includes a second pallet 910 and a second cylinder 911. A second support block 912 is installed at the front end of the second pallet 910, and the other end of the second pallet 910 is connected to the second cylinder 911. The second cylinder 911 drives the second pallet 910 to extend or retract through telescopic movement. When the second cylinder 911 extends, it pushes the second pallet 910 to extend, and the second pallet 910 drives the second support block 912 to extend. When the second cylinder 911 retracts, it pulls the second pallet 910 to retract, and the second pallet 910 drives the second support block 912 to retract.

[0027] like Figure 5 As shown, the clamping assembly 92 includes a third cylinder 921, a mounting block 922, a mounting base 923, a connecting plate 924, and an opening clamping arm 925. The opening clamping arm 925 is movably connected to one end of the mounting block 922, and the other end of the mounting block 922 is fixedly connected to the third cylinder 921. One end of the connecting plate 924 is movably connected to the opening clamping arm 925, and the other end of the connecting plate 924 is movably connected to the mounting base 923. The mounting base 923 is fixedly mounted on the third cylinder 921. When the third cylinder 921 extends or retracts the mounting block 922 through its telescopic movement, it will also cause the opening clamping arm 925 to rotate clockwise or counterclockwise. When the third cylinder 921 extends, it pushes the mounting block 922 forward. The mounting block 922 drives the opening clamp arm 925 to move clockwise. At this time, the opening clamp arm 925 rotates downward and presses down on the tray clamp (the tray clamp is mainly used to hold the circuit board), opening the tray clamp. Simultaneously, the opening clamp arm 925 also serves to position the tray together with the pallet-pressing assembly 90 and the pallet-supporting assembly 91. When the third cylinder retracts, it pulls the mounting block 922 backward. The mounting block 922 drives the opening clamp arm 925 to move counterclockwise, releasing the tray clamp. In this invention, the opening clamp assembly 92 is installed behind the pallet-supporting assembly 91.

[0028] The number of paddle tray assembly 90, support tray assembly 91, and clamping assembly 92 can be multiple, preferably four. Two paddle tray assemblies 90, two support tray assemblies 91, and two clamping assemblies 92 are installed on the left and right supports respectively. The paddle blocks 901 of the paddle tray assembly 90 on each support correspond to each other. The support tray assembly 91 and clamping assembly 92 on the left support correspond to the support tray assembly 91 and clamping assembly 92 on the right support. The clamping arms 925 on the clamping assembly 92 are set to correspond to the tray clamps.

[0029] like Figure 6 As shown, the barcode reader group 93 includes a mounting bracket 931 and a barcode reader 932. The barcode reader 932 is mounted on the mounting bracket 931, and the mounting bracket 931 is mounted on one of the supports (left support or right support).

[0030] The clamping mechanism also includes a through-beam sensor 93 and a diffuse reflection sensor 94. The through-beam sensor 93 is used to detect whether there is a plate in the tray, and the diffuse reflection sensor 94 detects whether the tray has reached the designated position. The through-beam sensor 93 and the diffuse reflection sensor 94 are respectively mounted on the left and right supports.

[0031] The clamping mechanism of the present invention can be used alone or installed in a pallet take-up and take-down machine suitable for touchless trays; touchless tray: non-contact tray.

[0032] Working process of the clamping mechanism:

[0033] Step 1: When the sensor detects the presence of a tray, the cylinder of the tray-tapping assembly 90 extends, causing the tapping block 901 to extend, and the cylinder of the tray-supporting assembly 91 extends, causing the second support block 912 to extend. The two work simultaneously to position the tray.

[0034] Step 2: After positioning, the barcode reader 932 starts up, automatically enters and summarizes the information of the produced board into the information processing terminal;

[0035] Step 3: After input, the cylinder of the clamping assembly 92 extends to rotate the clamping arm 925 downward (the clamping arm 925 rotates clockwise, and one clamping arm 925 corresponds to opening one clamp on the tray that holds the circuit board), pressing on the clamp on the tray. The tray clamp is opened by the clamping arm 925. When feeding the board, the board on the tray can be removed. When collecting the board, the circuit board corresponding to the tray can be placed on the tray.

[0036] Step 4: After the pallet is supported by other mechanisms, the cylinder of the clamping assembly 92 retracts, and the clamping arm 925 retracts backward (rotates counterclockwise) to release the clamp on the pallet.

[0037] The beneficial effects of the present invention are: 1. The clamping mechanism of the present invention is suitable for touchless trays, does not require a platform to assist in clamping the tray, and occupies less space; 2. The clamping mechanism of the present invention is equipped with a barcode reader, which can automatically input and summarize the information of the produced board to the information processing terminal to realize the automation of board production.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
