Description

Technical Field

[0001] This utility model relates to the field of teach pendant technology, and specifically to a robotic teach pendant that can be held by both hands. Background Technology

[0002] A teach pendant is a handheld device used for manual operation, programming, parameter configuration, and monitoring of robots or robotic arms. Currently available dual-handheld industrial robot teach pendants are mainly Japanese brands, and typically include a display screen, an emergency stop switch, a mode switch, a safety switch, and a handwheel. The safety switch is located at the bottom of the teach pendant in the left-hand position, and the handwheel is located above the right thumb. During teaching operations, the left palm is used to press the safety switch, while both thumbs operate the buttons on the teach pendant panel.

[0003] Chinese patent application CN 115519562 A discloses a teach pendant and motion control system. The teach pendant includes a display, a touchscreen, buttons, and adjustment knobs (handwheels). The display is in portrait orientation, which reduces the overall size of the teach pendant and shortens the lever arm in the left-right direction, alleviating hand fatigue caused by prolonged use. The housing includes a first side plate and a second side plate, with adjustment knobs on either side plate for easy access by pressing buttons and rotating knobs.

[0004] Existing two-handed teach pendants have a button width of 140mm and a grip width of 50mm, resulting in limited thumb movement when held with both hands. Prolonged use can easily lead to hand and thumb fatigue. The unsuitable button layout, determined by the handwheel design and software, fails to provide optimal ergonomics based on the typical hand size and habits of Chinese users. Utility Model Content

[0005] Due to the aforementioned deficiencies in the existing technology, this application provides a two-handed robotic teaching pendant that can reduce grip fatigue and improve human-computer interaction efficiency.

[0006] To achieve the above objectives, this utility model provides a two-handed robot teach pendant, including a housing and a circuit board disposed inside it; an emergency stop adjustment area is provided on the top of the housing on the operating front; a touch display screen, a button grip area, and a wiring area are arranged sequentially below the emergency stop adjustment area on the operating front of the teach pendant.

[0009] This invention reduces the size of the teach pendant by eliminating the handwheel, thereby reducing its thickness and width. The eliminated handwheel function allows for quick interface switching and selection via a human-machine interface and directional buttons. The function keys that account for more than 8% of the operation during the teaching process are concentrated in the area covered by the thumb when holding the pendant with both hands, reducing the frequency of hand movement during operation and reducing fatigue during long-term operation.

[0010] In some embodiments, the grip portion is ergonomically designed, with a spline-curved contour conforming to the anatomical features of the hand. This design ensures a comfortable and stable grip, reducing fatigue.

[0011] In some embodiments, a mode switch and an emergency stop button are respectively provided on both sides of the emergency stop gear adjustment area.

[0012] In some embodiments, the ABC and XYZ directional keys are respectively located in different thumb-covering areas on both sides, and the up, down, left, right, and select keys are also located in different thumb-covering areas on both sides. This optimized button layout makes the user interface clearer, reduces the error rate, and improves human-computer interaction efficiency.

[0013] In some embodiments, a raised ridge is provided on the outer shell of the operating back and on the outer side of the grip portion; a groove is provided in the middle of the outer shell of the operating back to facilitate hand gripping in conjunction with the raised ridge.

[0014] In some embodiments, the surface or side of the protruding ridge is provided with a safety switch button, which allows the user to press it quickly when necessary to ensure safety.

[0015] In some embodiments, a hanging loop is provided at the top of the operating back of the housing for suspending the teach pendant.

[0016] In some embodiments, a protruding protective plate is provided above the emergency stop gear shift area and on the outer casing to protect the main body of the teaching pendant.

[0017] In some embodiments, at least one side of the grip portion and the outer casing are provided with threading grooves for assembling wristbands.

[0018] Compared with the prior art, the present invention has the following technical effects, including but not limited to:

[0019] This invention eliminates the handwheel assembly, reducing the thickness of the teach pendant and the width of the grip. The grip area features an ergonomic curved design that fits the palm. The button layout is optimized, and combined with the human-machine interface design, it reduces operator fatigue during long-term use of the teach pendant, improves human-machine efficiency, and promotes debugging efficiency, while also reducing the weight of the teach pendant.

[0033] The teaching pendant features a touch display screen 200, a button grip area 400, and a wiring area 500, arranged sequentially below the emergency stop adjustment area 300 on its operating front. Each area is secured via holes in the housing 100. The touch display screen 200 can be in any orientation, either landscape or portrait.

[0034] The width of the button grip area 400 is no greater than 135mm, and the thickness is no greater than 40mm. Its sides are the hand grip sections 410, and the center of the front is the button section 420. The ABC directional keys, XYZ directional keys, up, down, left, and right keys, selection keys, and commonly used programming process command keys are located within the thumb-covered area of ​​the button section 420. Based on the frequency of daily operation, concentrating the function keys that account for more than 8% of the operations during teaching operations within the thumb-covered area when holding the button with both hands effectively reduces the frequency of hand movement during operation and reduces fatigue during long-term operation.

[0035] Better yet, see Figure 6 The ABC and XYZ directional keys are positioned on opposite sides of the user's thumb area, as are the up, down, left, right, and select keys. This optimized button layout makes the user interface clearer, reduces error rates, and improves human-computer interaction efficiency.

[0036] The teaching pendant is used as follows: the operator holds the pendant with both hands on the outside of the hand grips 410 on both sides of the lower part of the pendant, and manually operates the robot, writes programs, configures parameters and monitors them by operating the functional components of the emergency stop gear adjustment area 300, the buttons of the button section 420 and the touch display screen 200.

[0037] See some preferred examples. Figure 1 and Figure 2 The grip 410 features an ergonomic design, with a spline-curved contour that conforms to the anatomical features of the hand. This design ensures a comfortable and stable grip, reducing fatigue.

[0038] See some preferred examples. Figure 2 and Figure 4 The outer casing 100 on the back of the operating device has a raised ridge 110 on the outer side of the grip portion 410; a groove 150 is formed in the middle of the outer casing 100 on the back of the operating device, which, together with the raised ridge 110, facilitates hand gripping. When holding the device, the hand can stably grasp the teaching pendant through the groove 150, the raised ridge 110, and the grip portion 410. See also Figure 4 and Figure 5 According to the needs of the teach pendant user, a safety switch button 600 can also be installed on the surface or side of the protruding ridge 110.

[0039] See some preferred examples. Figure 2 and Figure 3 The top of the back of the housing 100 is provided with a hanging ring 120 for suspending the teach pendant.

[0040] In some preferred examples, a protruding guard plate 130 is provided above the emergency stop adjustment area 300 and on the housing 100 to prevent impacts from causing an emergency stop and damage to the switch button.

[0041] In some preferred examples, at least one side of the grip portion 410 has a threading groove 140 on the upper and lower sides and the outer casing 100 for attaching a wristband (not shown in the figure).

[0042] As described above, this invention effectively reduces the thickness and width of the teach pendant by eliminating the handwheel, thus reducing its overall size and making it more suitable for Chinese users. The grip area features an ergonomic design, with a spline-curve contour that conforms to the anatomical features of the hand. The eliminated handwheel function allows for quick interface switching and selection via a human-machine interface combined with directional buttons. Through extensive practical operation verification and research, the function keys, which account for more than 8% of the operations during teaching, are concentrated within the thumb coverage area when holding the pendant with both hands, reducing the frequency of hand movement during operation and minimizing fatigue during long-term use.
