Description

Technical Field

[0001] The utility model relates to the technical field of safety protection, in particular to a safety protection device based on photoelectric detection technology. Background Art

[0002] In the chip manufacturing industry, wafers undergo a series of production processes to become finished chips. Before shipping, the chips need to be vacuum-tapped and packaged before they can be shipped to customers. The mainstream vacuum tape packaging machines currently on the market are small, highly efficient, and stable. However, manual operation of the machine after frequently disabling the interlocking device can cause injuries to personnel when inspecting machine problems. In actual production, there have been cases of employees in the equipment management department being injured by the robotic arm of the tape machine.

[0003] Due to the current operation and maintenance management of the equipment, the opening of the safety protection door conflicts with the automatic operation and execution of all functions of the equipment. The safety door must be blocked to enable the equipment to operate and the equipment maintenance personnel to observe abnormal points in the equipment operation. After the safety door is blocked, the equipment management personnel can easily forget the safety risks when operating and observing the equipment, resulting in entering the dangerous area and getting injured. Therefore, it is necessary to design a new set of safety protection devices that can prevent workers from being injured even when the interlock device of the machine itself is frequently closed. Utility Model Content

[0004] The purpose of the utility model is to provide a safety protection device based on photoelectric detection technology, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a safety protection device based on photoelectric detection technology, comprising two end plates, the two end plates being symmetrically arranged;

[0006] Both sides of the side wall of the two end plates close to each other are connected with clamping blocks, the outer wall of the end plate is fixedly connected to the fixing plate, the outer wall of the fixing plate is fixedly connected to the bracket, the tail end of the bracket is fixedly connected to the connecting plate, the bottom of the connecting plate is fixedly connected to the mounting plate, and a photoelectric detector is arranged between the two end plates, the photoelectric detector includes a transmitting end and a receiving end, the transmitting end and the receiving end are clamped between the corresponding two clamping blocks, and the inner side walls of the transmitting end and the receiving end are movably connected with a plurality of evenly distributed photoelectric transmitters and photoelectric receivers.

[0007] By adopting the above technical solution, the photoelectric detector and the equipment master controller are interconnected by signal, and multiple photoelectric emitters and photoelectric receivers are used to form a fence-type optical path, so that equipment management personnel can observe the operating status of the equipment without stopping the machine and shielding the safety door, and detect abnormalities in time. At the same time, during the inspection of the equipment by personnel, if the limbs or other parts of the personnel touch the optical path, the photoelectric detector will feedback the signal to the equipment master controller, so that the equipment will stop running immediately to prevent the equipment operation mechanism from causing harm to personnel. By installing the photoelectric emitter and photoelectric receiver on the carrying platform at different angles and different spacings, a safety protection net with a special photoelectric detection network is formed. By adjusting the optical path angle, optical path spacing and the overall photoelectric detector up and down, as well as increasing or decreasing the detection optical path, the range of the protection area can be adjusted, thereby improving adaptability.

[0008] As a preferred embodiment of the present invention, a first bolt column is fixed to one end of the clamping block, and a strip hole is opened on the outer wall of the end plate corresponding to the first bolt column. The first bolt column passes through the strip hole and engages with the first nut.

[0009] By adopting the above technical solution, the clamping block and the first bolt column can be moved along the strip hole by loosening the first nut, thereby adjusting the distance between the clamping blocks on both sides, so as to adapt to transmitters and receivers of different sizes, thereby improving adaptability.

[0010] As a preferred embodiment of the present invention, the two side walls of the clamping block on the same side are both provided with through holes, second bolt columns pass through the two through holes, and the outer walls at both ends of the second bolt columns are engaged with matching second nuts.

[0011] By adopting the above technical solution, the two clamping blocks can be locked and positioned again by using the second nut in conjunction with the second bolt column, thereby further improving the stability of clamping the transmitting end and the receiving end.

[0012] As a preferred embodiment of the present invention, a clamping groove is provided on the inner side wall of the clamping block, and an adaptive rubber pad is glued into the clamping groove.

[0013] By adopting the above technical solution and setting the clamping groove and rubber pad, a high degree of fit is achieved when clamping the transmitter and the receiver, thereby improving the clamping stability.

[0014] As a preferred embodiment of the present invention, mounting holes are provided on both sides of the top of the mounting plate.

[0015] By adopting the above technical solution and setting the mounting holes, it is convenient to install and fix the entire device.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The technical solution of the present application is a safety protection device based on photoelectric detection technology. A plurality of photoelectric emitters and photoelectric receivers are respectively distributed at the transmitting end and the receiving end of the photoelectric detector, thereby forming a photoelectric detection protection. Once an unsafe signal is generated, the equipment can be quickly shut down to prevent people from accidentally entering the unsafe area with their fingers, palms or other body parts when observing the operating status of the equipment through the shielded safety door and getting injured. By installing the photoelectric emitters and photoelectric receivers at different angles and different spacings on the carrying platform, a safety protection net with a special photoelectric detection net is formed. By adjusting the optical path angle, optical path spacing and the overall photoelectric detection device up and down, as well as increasing or decreasing the detection optical path, the range of the protection area can be adjusted, thereby improving adaptability.

[0018] The photoelectric detection device mounting device designed in the present invention can support the increase in the size of the photoelectric detection device mounting platform. By increasing the size of the photoelectric detection device, the protection range can be further increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-3 , the utility model provides a technical solution: a safety protection device based on photoelectric detection technology, comprising an end plate 1, the number of the end plates 1 is two, and the two end plates 1 are symmetrically arranged;

[0028] A clamping block 14 is connected to both sides of a side wall of the two end plates 1 that are close to each other. A fixing plate 15 is fixedly connected to the outer wall of the end plate 1. A bracket 16 is fixedly connected to the outer wall of the fixing plate 15. A connecting plate 17 is fixedly connected to the tail end of the bracket 16. A mounting plate 18 is fixedly connected to the bottom of the connecting plate 17. A photoelectric detector 2 is provided between the two end plates 1. The photoelectric detector 2 includes a transmitting end 21 and a receiving end 22. The transmitting end 21 and the receiving end 22 are both clamped between the corresponding two clamping blocks 14. The inner side walls of the transmitting end 21 and the receiving end 22 are movably connected to a plurality of evenly distributed photoelectric transmitters and photoelectric receivers.

[0029] It should be noted that the photoelectric transmitter and the photoelectric receiver are movably connected to the transmitting end 21 and the receiving end 22 respectively, so that the angles of the photoelectric transmitter and the photoelectric receiver can be adjusted;

[0030] In actual use, the photoelectric detector 2 and the equipment master controller are interconnected by signal, and multiple photoelectric emitters and photoelectric receivers are used to form a fence-type optical path, so that equipment management personnel can observe the operating status of the equipment without stopping the machine and shielding the safety door, and detect abnormalities in time. At the same time, during the inspection of the equipment by personnel, if the limbs or other parts of the personnel touch the optical path, the photoelectric detector 2 will feedback the signal to the equipment master controller, so that the equipment will stop running immediately to prevent the equipment operation mechanism from causing harm to personnel. By installing the photoelectric emitters and photoelectric receivers on the carrying platform at different angles and different spacings, a safety protection net with a special photoelectric detection network is formed. By adjusting the optical path angle, optical path spacing and the overall photoelectric detector 2 up and down, as well as increasing or decreasing the detection optical path, the range of the protection area can be adjusted, thereby improving adaptability.

[0031] Furthermore, mounting holes are provided on both sides of the top of the mounting plate 18. The provision of the mounting holes facilitates the installation and fixation of the entire device.

[0032] Furthermore, a clamping groove 19 is provided on the inner side wall of the clamping block 14, and a matching rubber pad is glued into the clamping groove 19. The arrangement of the clamping groove 19 and the rubber pad ensures a high degree of fit when clamping the transmitting end 21 and the receiving end 22, thereby improving the clamping stability.

[0033] like Figure 1 and 3 As shown; a first bolt column 12 is fixed to one end of the clamping block 14, and a strip hole 11 is provided on the outer wall of the end plate 1 corresponding to the first bolt column 12, and the first bolt column 12 passes through the strip hole 11 and engages with the first nut 13;

[0034] By loosening the first nut 13 , the clamping block 14 and the first bolt column 12 can be moved along the strip hole 11 , thereby adjusting the distance between the clamping blocks 14 on both sides, thereby adapting to transmitters 21 and receivers 22 of different sizes, thereby improving adaptability.

[0035] Furthermore, through holes are formed on the side walls of the two clamping blocks 14 on the same side, and second bolt columns 3 pass through the two through holes. The outer walls of both ends of the second bolt columns 3 are engaged with matching second nuts 31.

[0036] The second nut 31 cooperates with the second bolt column 3 to lock and position the two clamping blocks 14 again, thereby further improving the stability of clamping the transmitting end 21 and the receiving end 22.

[0037] The implementation principle of the safety protection device based on photoelectric detection technology in the present application is: first install the mounting plate 18 at the specified position, then loosen the first nut 13 and the second nut 31, then loosen the clamps 14 on both sides, and then install the transmitting end 21 and the receiving end 22 of the photoelectric detector 2 in place respectively, and then lock it again. During use, the multiple photoelectric transmitters and photoelectric receivers on the transmitting end 21 and the receiving end 22 form a fence-type optical path, so that the equipment management personnel can observe the operating status of the equipment without stopping the machine and shielding the safety door, and detect abnormalities in time. At the same time, during the personnel inspection of the equipment, if the limbs or other parts of the personnel touch the optical path, the photoelectric detector 2 will feedback the signal to the equipment main controller, so that the equipment will stop running immediately to prevent the equipment operation mechanism from causing harm to personnel.
